House dust and soil are major sources of Pb exposure. Historically\, soil has been attributed as a major driver of house dust Pb. Understanding the phases o f house dust Pb is essential to elucidating potential sources of contamin ation and subsequent exposure. Additionally\, development of remediation techniques is of similar concern due to significant economical and ecolog ical consequences of soil excavation. Here\, we explore the Pb speciation and bioavailability of house dusts for a subset of US homes while also s howcasing a newly developed\, bioavailability-reducing Pb remediation tec hnique. Bulk and spatially-resolved X-ray absorption spectroscopy results are paired with bioaccessibility and relative bioavailability measuremen ts to explore Pb in house dust and Pb contaminated soils pre- and post-re mediation.

For instance\, direct solar desal ination exhibits considerable potential for alleviating the global freshw ater crisis. In this talk\, I will first go through our recent research e fforts to develop inexpensive solar-driven evaporation architectures usin g photothermal materials and systems. Its potential applications for zero -liquid-discharge water treatment using evaporation ponds will also be di scussed. However\, if the evaporated moisture cannot be collected\, they can only be considered as a "pollution" to the atmosphere. As the entropy sink\, the cold source is an integral part of a complete thermodynamic c ycle in all heat-producing technologies. The unique challenge is to obtai n coldness from renewable and sustainable sources. In the second part of this talk\, I will discuss our recent efforts on radiative cooling in wat er and energy sustainability. In particular\, the potential to recycle at mospheric water using passive cooling technology will be discussed.\nBiog raphy: \nDr. Qiaoqiang Gan is a Professor in Physical Science and Enginee ring Division\, KAUST.

Useful concepts such as surface tension and disjoining pressure\, however\, has seldomly been linked to the mechanics and physics of porous materials de spite their enormous internal surface area (one gram of some porous media can contain surface area as large as a football field).\nThis presentati on will demonstrate how the consideration of solid-fluid interface can ex plain several characteristic mechanical behaviors of porous geomaterials\ , including adsorption-induced deformation\, water-assisted grain crushin g\, and environment-enhanced fracture propagation.

The technological bottleneck impeding their implementation resides not with the material itself but in their reliable\, controlled synthesi s. Precision control over parameters such as CNT placement\, diameter\, c hirality\, growth rate\, and wall structure has yet to be demonstrated fo r isolated CNTs or for dense\, vertically oriented CNT films\, known as C NT forests. Chemical vapor deposition (CVD) techniques facilitate the syn thesis of CNT forests over large areas\; however\, the resulting CNT fore st ensemble properties often fall short of those predicted from volumetri c scaling. The reduction is believed to originate from the wavy\, interco nnected CNT morphology induced by self-assembly. We seek to understand CN T forest self-assembly kinetics and mechanics using in-situ SEM CVD synth esis\, complementary numerical simulation\, and machine learning tools. T his talk will provide our preliminary results with these tools and an out look for their integration to better understand and control the assembly of CNT forests.\n\nBiography: \nMatt Maschmann is an Associate Professor in the Mechanical & Aerospace Engineering Department at University of Mis souri Department and is co-director of the MU Materials Science and Engin eering Institute\, founded in 2022.

Curv ature as a design parameter is first investigated in the context of perio dic minimal surfaces\, which provide a platform for topological mechanica l metamaterials. We specifically illustrate configurations of 1D and 2D l attices dimerized through parametrizations that systematically break spat ial symmetries\, and that form the bases for opening non-trivial band gap s and for introducing interfaces that support topological valley modes. T heir existence is illustrated through vibration and wave propagation expe riments conducted on additively manufactured minimal surface samples\, wh ich illustrate the confinement of topologically protected edge states alo ng engineered interfaces and confirm the lack of significant backscatteri ng at sharp corners. This study supports the vision of minimal surfaces a s a general framework where geometrical modulations and symmetries can be introduced to achieve novel and unusual mechanical and acoustic function alities. \nIn the second part of the talk\, curvature is explored as a me an to induce spatial variations of the effective refractive index of wave guides. Graded refractive index distributions usually requires the use of metamaterials\, which pose manufacturing challenges\, and introduce band width limitations. It is here shown that the effect of a variable refract ive index is equivalently achieved by warping the waveguide in space. We specifically illustrate how elastic waves can be manipulated through curv ed surfaces characterized by generic Gaussian curvature distributions. By operating within the short wavelength limit\, we show that homogeneous c urved waveguides can be designed by relating the refractive index to the Gaussian curvature. Consequently\, the wave trajectories can be predicted by means of geodesic analysis of the surface followed by a classical ray tracing approach. Our theoretical predictions are validated by experimen ts conducted on additively printed curved waveguides which demonstrate ho w spatial curvature can be used for wave guiding and focusing using simpl e\, and possible reconfigurable\, structural configurations.

The parts affect each o ther leading to unique displays of their collective behavior at mesoscopi c or macroscopic scales. A typical example is the result of electromagnet ic fields interacting with inhomogeneous\, strongly scattering media. \nI t was a long-time belief that\, with increasing disorder\, the transport of light gradually slows down and\, eventually\, comes to a halt correspo nding to a localized state. However\, our experiments demonstrate that\, in fact\, different stages emerge in this evolution\, which cannot be des cribed by conventional scaling arguments. Strong evanescent-field couplin gs hinder the localization of wave resonances and impede the slowing down of diffusion . The emerging out-of-equilibrium process resembles the di ffusion of classical particles in spatially correlated random potentials and the thermalization of matter waves due to atomic collisions.\n\nThe s trong electromagnetic interaction between the discrete scattering element s leads to nonlocal space-time fingerprints in the emitted radiation. I w ill show how\, even in nonstationary conditions\, the cooperativity of ef fective\, non-resonant emitters leads to subradiant states that are prote cted from inherent disorder. The evolving spatio-temporal properties of r adiation maintain reciprocity and depend on the system's microstructure . \nAside from fundamental interest\, these paradigms could offer means fo r controlling the storage and release of energy in random media\, for mem ory or enhanced coupling applications. \n\nBiography: \nAristide Dogariu is University Trustee Chair and Pegasus Professor at CREOL\, the College of Optics and Photonics\, University of Central Florida.

They encode an embedding of an actual problem of interest within a family of problems and lead to broad insights and computational possibi lities. We introduce Rockafellians and illustrate their application in st ochastic optimization and machine learning\, especially to cases with lab el noise\, outliers\, and low-prevalence classes. Through Rockafellian re laxation\, we are able to explore a decision space broadly and discover s olutions that remain hidden for more conservative approaches to decision making under uncertainty such as distributional robust optimization.\n\nB iography: \nDr. Johannes O.

These changes have had and will continue to impact our numerical scientific software significantly. A new generation of software libraries and algorithms are needed for the effective and reliable use of (wide area) dynamic\, distributed\, and pa rallel environments. Some of the software and algorithm challenges have a lready been encountered\, such as management of communication and memory hierarchies through a combination of compile-time and run-time techniques \, but the increased scale of computation\, depth of memory hierarchies\, range of latencies\, and increased run-time environment variability will make these problems much harder.

Instead\, multiscali ng approaches have been developed that break the cycle into elementary st eps for which kinetic and equilibrium parameters can be obtained from MD. These parameters are combined in a stochastic kinetic model whose master equation is solved under varying external conditions such as ion concent rations and membrane potential.

Analytic methods for de tecting glyphosate at concentrations that are potentially hazardous are s parse. Due to climate change and unpredictable storm events\, understandi ng the transport patterns and risk exposures to glyphosate in hydrologica l and geological pathways are a challenging task. Additionally\, climate change disproportionately affects underserved people and has detrimental effects on their health due to exposure and vulnerabilities. With minimum access and/or adoption to sustainable technologies\, underserved communi ties are at the forefront of the global climate change crisis. This talk discusses a straightforward method for quantifying glyphosate-based herb icides via 9-fluorenylmethylcholoroformate (FMOC-Cl) pre-column derivatiz ation and analysis by liquid chromatography with tandem mass spectrometry (LC-MS/MS). Furthermore\, this talk will discuss developed models to qua ntify the exposure risks to glyphosate. Lastly\, this seminar will explor e how Hobbs' research groups incorporates fundamental and applications fo r adaptive management techniques for co-creating with historically and in tentionally marginalized communities.\n\n\nBio\nDr. Hobbs develops waste management techniques for anthropogenic waste\, models glyphosate transpo rt in water systems\, converts waste to energy and investigates early ado ption of sustainable technologies.

Jones Distinguished Professor of Mechanical Engineering at Duke University. AB STRACT: You may be familiar with the saying "The best is the enemy of the good" (Voltaire)\, or "Perfection is the enemy of progress" (Churchill). It sounds counterintuitive. Most of us tend to associate the better perf orming with the more perfect. Is the saying true? This is a question of p hysics\, not opinion. I address it in terms of the physics of evolution ( constructal law). I predict in simple terms the 'enemy' relationship betw een performance and perfection (access to movement\, space\, and time). I t is natural. Everywhere we see it\, in human movement (life) in the city \, animal life\, athletics evolution\, vascular designs\, business\, and human diversity on the globe and in universities. From cause to effect\, nature 'happens' in this direction\, not the other way around: \n Freedom to change --> evolution --> performance (access) --> diversity.\ n\nADRIAN BEJAN (MIT SB 1971\, SM 1972\, PhD 1975) is the J.A. Jones Dist inguished Professor of Mechanical Engineering at Duke University. His res earch covers thermodynamics and design & evolution in nature. \n He w as awarded the Benjamin Franklin Medal 2018 ""For his pioneering interdis ciplinary contributions in thermodynamics and constructal theory\, which predicts natural design and its evolution in engineering\, scientific\, a nd social systems."\n Professor Bejan is the author of more than 30 b ooks and 700 peer-referred articles. His h-index is 110 with 90\,000 cita tions on Google Scholar. He received 18 honorary doctorates from universi ties in 11 countries\, such as ETH Zurich\, and The Sapienza University o f Rome.\n In the world impact rankings\, Adrian Bejan is ranked among the top 0.01% of world scientists\, specifically\, 11th in all Engineeri ng disciplines\, 1st in Pratt\, and 5th at Duke\, cf.\, "Updated science- wide author databases of standardized citation indicators\," 19 October 2 021\, DOI:10.17632/btchxktzyw.3\, by John P.A.

However\, it remains a per sistent challenge in large-scale weather and climate modeling systems to represent these transport processes. In the first part of the talk\, we d iscuss the transport of heat in the context of mixed convection for an id ealized coastal-rural-urban setting by conducting large-eddy simulations. To further understand the impact of urban canopy\, a model based on the mean momentum and energy transport equations is proposed to explain the d ifferent mechanisms that urban canopy\, thermal heterogeneity\, and mean advection contribute to the canopy urban heat island effect. In the secon d part of the talk\, we focus on the implications of anthropogenic source s of microplastic particles\, especially fibers in global atmospheric lon g-range transport. We develop a semi-analytical model based on the slende r body theory and parameterization of the rotational dynamics. The model is applied to field measurement data of airborne microplastic fibers coll ected in the US national parks and implications of the results will be di scussed.

When materials beco me anisotropic\, refraction and often reflection are anomalous: the direc tions of the beams depend on anisotropy and on orientation of the interfa ce\, in addition to direction of the incident beam. In some geometries th e angle of incidence is not equal to the angle of reflection\, opening th e possibilities to significant reshaping of light. In this talk we discus s the implications of anomalous refraction and reflection that accompany hyperbolic dispersion in metamaterials for confining light to the nanosca le and for extracting light from highly confined areas. \nWe show that in planar structures high confinement (and high Purcell effect) is often ac companied by weak coupling efficiency. In non-planar structures\, such as in conical waveguides with hyperbolic cores (photonic funnels)\, anomalo us reflection enables simultaneous enhancement and confinement of the ele ctromagnetic fields\, by directing light that originally propagates along the optical axis towards the tip of the properly designed structures. An omalous reflection can be further utilized to out-couple the emission fro m lossy (but high-optical-density) modes propagating along critical angle directions\, towards low-loss diffraction-limited beams. The latter proc ess may alleviate the trade-off between high Purcell factors and high emi ssion efficiency DURATION:PT1H DTSTAMP:20230822T140742Z DTSTART;TZID=America/New_York:20230927T120000 LAST-MODIFIED:20230822T140742Z LOCATION;X-BEDEWORK-UID=18832e99-20476e5b-0120-58864347-000000be:Fitzpatri ck Center Schiciano Auditorium Side A\, room 1464 STATUS:CONFIRMED SUMMARY:DMI/MEMS Seminar Presented by Prof. Viktor A.

This regime includes abundant natural and waste heat sources\, but there is currently no reasonable method to harvest the energy. We are pursuing an idea \nbased on the use of first order phase transformations with either an abrupt change of magnetization or \npolar ization at the transformation. In the ferromagnetic case the electricity is harvested by induction\; in the ferroelectric case\, by capacitance. It is a "direct" method in the sense that there is no separate electrica l \ngenerator. We survey the theory of this method\, the design of the m aterials and devices\, and the analysis of various cycles. We compare th eoretical predictions and the behavior of a prototype under cyclic heatin g/cooling. \nThese devices provide interesting possible ways to recover the vast amounts of energy stored on earth at small temperature differenc e. They move heat produced by natural and man-made sources from higher to lower temperature and therefore contribute negatively to global warming.

This t alk will introduce the concept of distributed sensing using technologies such as digital image correlation (DIC) and distributed fiber optic sensi ng (DFOS). A series of infrastructure monitoring case studies involving b oth reinforced concrete and steel structures will be used to illustrate h ow these distributed sensing technologies can provide insights into struc tural behavior that have never before been possible. Three case studies w ill be used to demonstrate how these new insights can be used in the desi gn of new structures and the assessment of existing structures to keep th em in service longer thus reducing their carbon footprint. In the first c ase study\, the use of distributed data to analyze the behavior of reinfo rced concrete beams in a way that has never before been possible will be introduced. The second case study will look at how distributed sensors mi ght be used to detect thermal buckling in rail tracks while at the same t ime illustrating that there are also challenges that come with having suc h robust data sets that must be overcome. The final case study will bring together field monitoring and lab data to better understand the performa nce of buried corrugated steel culverts under vehicle load and highlight how current design procedures do not capture this behavior.

Key to the succe ss of these techniques is the availability of very large sets of images a nd text along with models that are able to digest such large datasets. Un fortunately\, we have not been able to replicate the success of generativ e AI models in the context of robotics. An important problem is the lack of data suitable to train powerful\, general models for robot decision ma king and control. \nIn this talk\, I will discuss our ongoing efforts to ward developing the models and generating the kind of data that might lea d to foundational manipulation skills for robotics. To generate large am ounts of data\, we sample many object rearrangement tasks in physically r ealistic simulation environments and apply task and motion planning to ge nerate high quality solutions for them. We will then train manipulation skills so that they can be used across a broad range of object rearrangem ent tasks in unknown\, real-world environments. We believe that such ski lls could provide the glue between generative AI reasoning and robust exe cution in the real world.\n \nDIETER FOX is Senior Director of Robotics R esearch at NVIDIA and Professor in the Paul G.

Smalyukh\, Profe ssor of Physics\, University of Colorado Boulder. Professor Smalyukh will give a talk on "Knotted Chiral Meta Matter." ABSTRACT: Topological order and phases represent an exciting research frontier\, but knots in fields were postulated to behave like particles already starting from Gauss and Kelvin. Experimentally knots in order parameter fields were found only a s transient features and could not self-assemble into three-dimensional c rystals. I will describe energetically stable solitonic knots and knotted vortices that emerge in the physical fields of chiral liquid crystals an d magnets. While spatially localized and freely diffusing in all directio ns\, they behave like colloidal particles and atoms\, self-assembling int o crystalline lattices with open and closed structures\, as well as formi ng low-symmetry mesophases and gas- or liquid-like states. A combination of energy-minimizing numerical modeling and nonlinear optical imaging unc overs the internal structure and topology of individual solitonic knots a nd the various hierarchical crystalline and other organizations that they form. These solitonic knots are robust and topologically distinct from t he host medium\, though they can be morphed and reconfigured by weak stim uli like electric or magnetic fields. I will discuss their stability in m olecular and colloidal liquid crystals of different symmetries and will s how how low-voltage electric fields can switch between the heliknoton and hopfion embodiments of such knot solitons while preserving their topolog y. Finally\, I will discuss how this emergent paradigm of knotted soliton ic matter could allow for imparting new designable material properties an d for realizing phases of matter that so far could not be found in natura lly occurring materials.\n\nIVAN I.

Compellingly\, these techniques have become invaluable tools for applica tions ranging from topology optimization\, to uncertainty quantification\ , to real-time prediction\, to multi-scale modeling and beyond. Typically \, researchers take either a "problem-centric" or "model-centric" approac h to this work. Namely\, they focus on either an overarching engineering challenge\, or they focus on developing machine learning methods and mode l architectures. In this talk\, we will present a "data-centric" approach to data driven modeling of mechanical systems. Specifically\, we will di scuss work where we focus on defining and curating datasets as our top pr iority [1]. First\, we will share our work in developing and disseminatin g benchmark datasets for engineering mechanics problems [2\, 3]. In addit ion to describing these datasets\, we will also discuss our recent work i n investigating deep learning model calibration [4]. Then\, we will share our work in defining an open science based methodological foundation for data driven modeling of (bio)mechanical systems. In brief\, we envision a methodological framework with three essential components: (1) open acce ss datasets\, (2) open source software to extract interpretable quantitie s of interest from these data\, and (3) combined mechanistic and statisti cal models of (bio)mechanical behavior informed by these data. As an illu strative example\, we will discuss our recent collaborative work in cardi ac tissue engineering [5\, 6]. Overall\, the goal of this talk is to spar k discussion and inspire future work on "data-centric" approaches to mech anical modeling. \n\n[1] https://imechanica.org/node/25935 \n[2] https:// open.bu.edu/handle/2144/39371\n[3] https://elejeune11.github.io/\n[4] htt ps://doi.org/10.1016/j.mechmat.2023.104749\n[5] https://joss.theoj.org/pa pers/10.21105/joss.05322\n[6] https://arxiv.org/abs/2308.04610 DURATION:PT1H DTSTAMP:20231009T150555Z DTSTART;TZID=America/New_York:20231106T120000 LAST-MODIFIED:20231009T150555Z LOCATION;X-BEDEWORK-UID=18832e99-20476e5b-0120-58864347-000000be:Fitzpatri ck Center Schiciano Auditorium Side A\, room 1464 STATUS:CONFIRMED SUMMARY:CEE Seminar - Data driven modeling of mechanical systems UID:CAL-8a03932d-8a96243a-018b-14f92cd9-00001729demobedework@mysite.edu URL:http://cee.duke.edu X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Main:/user/public-user/Utili ties/Main X-BEDEWORK-ALIAS;X-BEDEWORK-PARAM-DISPLAYNAME=Panel_Seminar_Colloquium:/us er/public-user/Lectures_Conferences/Panel_Seminar_Colloquium X-BEDEWORK-SPEAKER:Emma Lejeune\, Boston University\, Assistant Professor in the Mechanical Engineering Department X-BEDEWORK-DUKE-SERIES:CEE Fall Seminar Series 2023 X-BEDEWORK-IMAGE-X1:0 X-BEDEWORK-IMAGE-Y1:32 X-BEDEWORK-IMAGE-X2:758 X-BEDEWORK-IMAGE-Y2:537.3333333333333 X-BEDEWORK-IMAGE-CROP-WIDTH:758 X-BEDEWORK-IMAGE-CROP-HEIGHT:505.33333333333326 X-BEDEWORK-IMAGE-ALT-TEXT:Emma Lejeune X-BEDEWORK-SUBMITTEDBY:nh143 for Civil and Environmental Engineering (CEE) (agrp_PrattSchool_CEE) X-BEDEWORK-IMAGE:/public/Images/Lejeune_headshot[47]_20231009030555PM.jpg X-BEDEWORK-THUMB-IMAGE:/public/Images/Lejeune_headshot[47]_20231009030555P M-thumb.png END:VEVENT BEGIN:VEVENT CATEGORIES:Engineering CATEGORIES:Lectures/Conferences CATEGORIES:Other CATEGORIES:Utilities CATEGORIES:Lecture/Talk CATEGORIES:Meeting CATEGORIES:Main CONTACT;X-BEDEWORK-UID=8a0290b4-860465b2-0186-32feb568-0000477d:Spaulding\ , Amy CREATED:20230508T143737Z DESCRIPTION:Thomas Lord Department of Mechanical Engineering & Materials S cience\nFall 2023 Seminar Series with Brian Holm-Hansen\, Program Officer \, Flight Dynamics & Control\, Office of Naval Research. \n\nTitle: "Nava l Flight Dynamics & Control Research"\n\nAbstract: The Office of Naval Re search (ONR) funds academia\, industry and government to advance scientif ic research and technology for the U.S. Navy and Marine Corps.

However\, pinpointing the speci fic impacts of design features proves to be challenging. While significan t advancements have been made using sensing\, feedback\, and control in " smart buildings"\, outcomes have focused primarily on energy savings\, th ermal comfort\, and security. Buildings of the future should go beyond th is to infer and support the mental and physical well-being of the occupan ts. A scientific approach to designing buildings for wellbeing can both c reate knowledge as well as improve the physical and mental health of larg e populations. Our team with expertise in architecture\, structural and m aterials engineering\, human-computer interaction\, psychology\, environm ental behavior\, and security\, privacy\, and law is examining how interi or features (e.g.\, materials\, lighting\, and artwork representing diver se identities) relate to multifaceted dimensions of well-being. Through o nline studies\, controlled laboratory experiments\, and virtual reality s tudies\, we have been exploring the effects of these varied features on b iopsychosocial indicators of well-being including belonging\, stress\, cr eativity\, and pro-environmental concern\, measured through physiological sensors and self-reported assessments. The results of several related st udies and their implications will be presented\, as well as methodologica l challenges surrounding the design\, experimentation\, and operation of human-centered built environments.

These materials exhibit phase transitions\, changes in solubility\, and nanoscale mechanical alterations triggered by extern al stimuli\, particularly light\, through molecular-level structural chan ges. While the photo-switching of molecules has primarily been studied in dilute solutions\, understanding this process in condensed liquid or sol id environments is crucial for successful real-world applications. Curren tly\, there is a lack of fundamental knowledge regarding the interaction between light and molecules in condensed phases\, as well as the impact o f photomechanical switching on intermolecular interactions.\n\nThis prese ntation aims to elucidate the design principles behind optically-controll able materials that integrate organic photoswitches\, ranging from azoben zenes to hydrazones. Extensive exploration of various photochromic core s tructures and functional groups has been conducted to gain insights into the structure-property relationship of these stimuli-responsive material systems. Additionally\, the talk will delve into the application of photo -controlled materials in solar photon and thermal energy storage\, as wel l as sustainable catalysis.

CPSs have even expanded to include human-in -the-loop control\, where humans serve as operators or supervisors. Whil e these paradigms have been wildly successful for the design and operatio n of physical systems decoupled from-or weakly coupled to-human social co ntexts\, there are entirely unexplored human benefits derived from infras tructure that have yet to be scientifically understood and exploited. Th is is based on the hypothesis that the design and management of infrastru cture plays a role in shaping human behavior\, which has been more qualit atively explored in urban design and social science settings. For instan ce\, social infrastructure (i.e.\, infrastructure supporting social inter action) is not social capital itself\, but rather the physical space and infrastructure that determines whether social capital develops. There is an urgent need to reimagine current CPS theory\, tools\, and frameworks to even make it possible to address systems where human behavior is centr al. This talk proposes that the existing CPS paradigm be radically alter ed such that physical infrastructure is controlled to meet social\, or hu man-centered objectives. This work deviates from existing-and highly lim iting-agent-based modeling (ABM) approaches by proposing the use of data- driven\, intelligent agents to mimic human behavior\, including human-hum an and human-infrastructure interactions. We advocate for a hybrid appro ach\, hierarchical imitation and reinforcement learning (HILRL)\, that be tter reflects human decision-making processes. HILRL leverages reinforce ment learning's capacity to mirror human decision-making behavior while b enefiting from imitation learning's capacity to incorporate real-world da ta. We demonstrate the effectiveness of this hybrid approach through a s imulated conference room case study\, illustrating the cooperative intera ctions of human agents in a social setting and offering insights into the ir collaborative behaviors.

Rao\, PhD\, Professor of M echanical and Aerospace Engineering\, University of Florida. Title: "A No vel Computational Framework for the Numerical Solution of Complex Constra ined Optimal Control Problems." Abstract: A novel computational framework is described for solving complex constrained nonlinear optimal control p roblems. The framework has a wide variety of applications in aerospace an d mechanical engineering. The basis of the framework is the new class of hp-adaptive Gaussian quadrature methods that transcribe the continuous op timal control problem to a finite-dimensional nonlinear optimization prob lem. The hp-adaptive methods have the feature that high accuracy can be o btained with a significantly smaller mesh when compared with traditional fixed-order methods while accurately capturing nonsmoothness or rapidly c hanging behavior. The hp-adaptive methods employed using advanced sparse nonlinear programming (NLP) solvers. The derivatives required by the NLP solvers are obtained using a new approach to algorithmic differentiation where efficient derivative source code is produced through a method that combines operator overloading with source transformation. The mathematica l foundation of the framework is provided and examples are given that dem onstrate the improvement over previously developed approaches. Finally\, future directions of the approach are discussed.\n\nANIL V.

How is such longevity possible? What is the molecular basis of such longe vity? The physiology of fast-growing bacteria is well characterized\, but relatively little is understood about how bacteria stay alive when they are not growing. We have been studying this crucial phase of the bacteri al life cycle. This is not just an academic exercise\; non-growing bacter ia can be useful. For example\, they are excellent biocatalysts because t hey can convert substrates that might be used for growth to value-added p roducts. Our work is with a phototrophic bacterium that is an excellent b iocatalyst for biofuel production when in growth arrest. I will describe our work on molecular mechanisms of longevity in this bacterium\, which i s named Rhodopseudomonas palustris.

Our solution to this problem i s "Engineered Living Materials"\, materials in which biological organisms are embedded within traditional plastic materials. The biological compon ent is programmed to carry out a complex function\, in this case\, enviro nmental remediation. Two projects will be described here: 1) using cyanob acteria as a source for pollutant decontamination and 2) embedding bacter ial spores in plastics as a catalyst for biodegradation. In the first pro ject\, we program the cyanobacteria to express a laccase enzyme that is a degrader of common organic pollutants. The cyanobacteria are then embedd ed in a hydrogel allowing them to filter and clean the water from the pol lutant. The second project uses evolution to make spore forming bacteria amenable to polymer melt processing for incorporation into thermoplastic polyurethanes. These bacteria can germinate and then biodegrade the polym er at of the plastics' life cycle. These two projects demonstrate the bea uty of repackaging natural biosynthetic functions to improve the environm ent.

A phenomenon is called a rare event when the amount of time that elapses before its o ccurrence is orders of magnitude longer than the time needed for its comp letion. Rare events are ubiquitous in nature and span a wide range of phe nomena such as earthquakes\, telecommunication and power grid failures\, protein folding\, genetic mutations\, and crystallization. Capturing the statistical nature of such events is key in many applications\, including materials synthesis\, climate modeling\, bioengineering and medicine. Un fortunately\, achieving this with conventional experiments or simulations is inefficient at best as the waiting times for observing a single rare event can surpass the experimentally or computationally accessible timesc ales by several orders of magnitude. This becomes an almost impossible un dertaking when the rate of occurrence of a rare event is astronomically s mall. Under such circumstances\, specialized sampling techniques are nece ssary for capturing the statistical features of the corresponding rare ev ent.\n\nThis presentation will be dedicated to showcasing our work on cha racterizing rare events using an advance sampling technique known as forw ard flux sampling (FFS)\, alongside a brief discussion of a novel variant of FFS recently developed in my group suited for studying aggregation ph enomena such as nucleation. I will\, in particular\, discuss our applicat ion of FFS to probe the kinetics and microscopic mechanism of two scienti fically and practically important rare events\, namely heterogeneous crys tal nucleation\, and ion and solute transport through semipermeable nanop orous membranes.

Instead\, their integral effect on the mean flow and turbulence statistics near the surface is imposed through universal functions. However\, these universa l functions were initially developed for atmospheric flows over flat and homogenous conditions with the goal to characterize the so-called inertia l sublayer. It is only later that they were adjusted to include the repre sentation of vegetated canopies through changes in the so-called surface roughness parameter and displacement height. While this approach had the advantage of being computationally efficient and provided a simple recipe for representing near-surface flows over all types of land surface cover s\, it was later shown to underestimate the turbulent exchanges taking pl ace within and above the vegetated canopies. This is because it neglects the more complex turbulence mixing induced by the vegetated cover\, chara cteristic of the so-called roughness sublayer. To better capture the enh anced momentum\, energy\, and mass exchanges characteristic of vegetated canopies\, additional correction functions for implementation in ESMs had to be developed that would therefore better represent the hand-sake betw een the near-surface and canopy process with the inertial sublayer above. In this work we further explore the characteristics of the flow within t he roughness sublayer where these new roughness sublayer correction funct ions have been defined. For this purpose\, we study the flow over a serie s of vegetated canopies with different degrees of cover heterogeneity and forcing conditions. For the analysis\, we leverage some recent developme nts where the metric of turbulence anisotropy has been introduced as an a dditional non-dimensional parameter in traditional atmospheric surface la yer scaling relations as a means to generate new insight on the turbulenc e mixing processes immediately above the forested canopies. Results illu strate that while some type of turbulence exhibit the traditional roughne ss sublayer structure\, other types of turbulence exhibit a departure fro m it.

It studies artificial \n"materials" that take advantage of "mechanisms" (that is\, nontrivial \nenergy-free deformations) to achieve interesting macroscopic behavior. \nThe relevant mechanics is nonlinear\, since mechanisms invol ve large \nrotations. While there have been insightful studies of specifi c \nexamples\, some fundamental issues remain poorly understood. This tal k \nwill address two of them\, namely (a) how to analyze a metamaterial's \nmacroscopic behavior\, and (b) whether linear elastic calculations can \nstill be of use in the analysis of such systems\, despite the fact tha t \ntheir mechanisms involve large rotations? My talk will start with a \ nbroad introduction to this area\; then I'll discuss some recent work wit h \nXuenan Li\, which focuses on a particular (very rich) example -- the \nKagome metamaterial. This system is interesting because it has \ninfini tely many mechanisms\, yet it behaves macroscopically as a \nnonlinear el astic material whose stress-free states are compressive \nconformal maps.

Nevertheless\, the re remains confusion about their validity\, with past studies conflicting ly arguing that the same estimates can be either conservative or un-conse rvative. In this seminar\, a combination of centrifuge and numerical mode ling is used to explore the dynamic response of simple and complex earth retaining systems. \n\nThe complex case of dual row retaining walls is in itially studied to investigate their potential use as tsunami defence aga inst multi-hazard events\, e.g.\, combined earthquake and tsunami loading and liquefaction of the foundation soil. The combination of dynamic cent rifuge modeling and numerical analyses informed the different mechanisms governing the dynamic response when the system was founded in dry and liq uefiable soils. Insights made into the dynamic response of the retained s oil highlighted the importance of soil rocking under horizontal shaking. This hinted at a solution to the past confusion surrounding the seismic l imit state of retained soil.\n\nA simpler case of a level bed of retained soil is used to generalize the findings from the dual row walls. The com bination of dynamic centrifuge modeling and numerical analyses exposes th e importance of dynamic normal vertical effective stresses. This allows f or a more fundamental interpretation of the limiting dynamic stress state of geomaterials. Finally\, simplified analytical methods to estimate the limiting distribution and time histories of stresses in retained soil ar e proposed. Validation of these against the numerical predictions illustr ates a path forward to estimate the limiting horizontal stresses\, and th us forces\, for the improved seismic limit state design of earth retainin g structures.

The combination of nano-optics with computational approaches and active platforms will be discussed. These examples demonstrate the potent ial of nano-optics in enabling the next generation of smart sensors and d isplays\, particularly for small\, low-power platforms such as augmented reality devices\, internet of things (IoT)\, and more.\nBio: Zhujun Shi i s currently an optical research scientist at Reality Labs at Meta.
