Granular materials by design: new approaches for mapping desired properties of the aggregate to properties of individual particles (2016)

When we think of materials &amp;ldquo;by design&amp;rdquo;, we are envisioning a process that gets us from a design target, namely certain desired overall materials properties, to requirements for the constituent components. This is challenging because it requires us to invert the typical modeling approach in physics and material science, which starts from microscale components in order to predict macroscale behavior. How can one tackle this inverse problem for granular materials that are inherently disordered and far from equilibrium, and for which the target is not a thermodynamically favored &amp;lsquo;ground state&amp;rsquo;? I will discuss how concepts from artificial evolution make it possible to find with high efficiency particle-scale parameters best adapted to given target properties. In particular, I will show how one can find particle shapes that are optimized for specific desired outcomes, such as low aggregate porosity or high stiffness under compression. This approach uses large numbers of parallel molecular dynamics simulations together with optimization techniques based on artificial evolution. Optimized shapes are then validated by physical measurements that test large aggregates of 3D-printed versions of the particles. This approach has general applicability and opens up new opportunities for granular materials design as well as discovery.
Reduced‐bandwidth method for F‐19 imaging of perflubron (1992)

A reduced-bandwidth imaging method has been developed to eliminate the chemical shift artifacts in magnetic resonance (MR) imaging of the blood substitute perflubron (PFB) and simultaneously enhance the signal-to-noise ratio (SNR). The two strongest spectral peaks, which have relatively long T2 values (247 and 471 msec), were used. When the receiver bandwidth is reduced substantially by increasing the data acquisition time Ts, the bandwidth across the object becomes less than the chemical shift frequency. The reduced bandwidth eliminates misregistration by displaying the images corresponding to multiple spectral peaks on the same image plane simultaneously. An additional gain due to the reduced bandwidth is the reduced thermal Gaussian noise. Unfortunately, the increased Ts results in an increased TE, which causes the signal to be attenuated by T2 relaxation. The optimum measured Ts (and TE) values for successful image separation and maximum SNR were 120 and 144 msec for the two spectral peaks, respectively. The long TE also suppresses the rest of the downfield spectral peak cluster of PFB. The degree of magnetic field inhomogeneity and tissue susceptibility across the object may cause some limitations in the application of this technique; however, a composite radio-frequency pulse that will allow use of additional spectral lines and/or localized volume imaging techniques may be incorporated to overcome these limitations.
Nonlinear characterization of near infrared Polymethine, Squaraine and Tetraone dyes (2007)

Excited state absorption spectra for a series of near IR symmetric polymethine, squaraine and tetraone dyes were measured by the femtosecond pump - white light continuum probe technique. Structure-property relationships were revealed and explained with quantum- chemical analysis.
NCHRP Report 350 Compliance Testing of the Beam-Eating Steel Terminal System (1998)

An energy-absorbing guardrail terminal was developed at the Midwest Roadside Safety Facility in 1994 that met the safety criteria set forth in NCHRP Report 230. This terminal, known as the beam-eating steel terminal, or BEST, relies on the cutting of steel W-beams to absorb the energy of impacting vehicles. Since that time, a new set of safety standards has been developed to replace those set forth in NCHRP Report 230. These new criteria are published in NCHRP Report 350, with the most significant change being the replacement of the 2041-kg (4,500-lb) sedan test vehicle with a 2000-kg (0.75-ton) pickup. To ensure that the BEST system would perform well under these new, and more stringent, criteria, the system was subjected to the matrix of full-scale vehicle crash tests required by NCHRP Report 350. Several design changes were made to the terminal system during this development to improve the performance of the system. The results of this successful program are reported.
Experimental Demonstration of Turbulence-Resilient Object Reconstruction by Optoelectronic Mixing of Sequentially Transmitted Pairs of Laguerre-Gaussian Modes (2021)

We experimentally demonstrate turbulence-resilient object reconstruction by optoelectronic mixing of sequentially transmitted pairs of Laguerre-Gaussian (LG) modes to measure the object’s LG modal signature. The reconstructed object exhibits resilience to turbulence with D / r 0 up to 4.5.
Study of Pulse Laser Assisted Metalorganic Vapor Phase Epitaxy of InGaN with Large Indium Mole Fraction (2004)

The indium composition of the InGaN film increases with decreasing growth temperature; however, the crystalline quality of the film is poor when it is grown at low temperatures. To form a high-quality InGaN film with a large indium mole fraction, Nd: YAG pulse laser assisted metalorganic vapor phase epitaxy (MOVPE) was carried out at low temperatures. The results suggest that film quality can be improved by pulse laser irradiation on the surface of the film.
Hypermethylation of the calcitonin gene in the myelodysplastic syndromes. (1993)

It is well documented that the calcitonin gene area in the short arm of chromosome 11 is hypermethylated in most acute leukemias as well as in chronic lymphatic leukemia. In contrast, the gene is normally methylated during the chronic phase of the chronic myeloid leukemia but turns hypermethylated as the disease escalates. As the methylation of the calcitonin gene correlates with the disease activity in chronic myeloid leukemia, it seemed worthwhile to study the gene methylation in other premalignant hematologic conditions with a potential to terminate in fulminant acute leukemia. We report here on the calcitonin gene methylation in patients with myelodysplastic syndromes (MDS) using a methylation sensitive restriction enzyme HpaII and standard Southern blotting techniques. Bone marrow aspirates from a total of 26 MDS patients were studied. In 24 of these patients, the calcitonin gene was hypermethylated. There was no correlation between the methylation status and the morphological stage of the disease. All six patients with a blast count < 5% had a hypermethylated gene. Of the 19 patients with a blast count > 5%, 17 were hypermethylated only two having normal methylation status of the gene. It appears that the hypermethylation of the calcitonin gene area in the short arm of chromosome 11 may be an early event in the pathogenesis of the myelodysplastic syndromes. The methylation analysis may thus be of value as a diagnostic tool in MDS but an abnormal methylation pattern does not seem to have a direct relation with the degree of blast infiltration.
Supramolekulare Metallopolymere: Von linearen Materialien zu infiniten Netzwerken (2018)

Abstract Koordinationspolymere (coordination polymers, CPs) und supramolekulare Metallopolymere (supramolecular metallopolymers, SMPs) sind seit Jahrzehnten Gegenstand ausgiebiger Forschung. Spektakuläre Fortschritte in beiden Feldern haben neue Verbindungen hervorgebracht, die an der Grenze zwischen diesen beiden organisch‐anorganischen Gebieten liegen. An dieser Schnittstelle wurden Materialien entwickelt auf Basis unterschiedlicher Konzepte wie molekularem Flechten, supramolekularen Clustern und Hybriden aus Metall‐organischen Gerüstverbindungen und Polymeren. Dieser Kurzaufsatz gewährt einen Einblick in die intellektuelle Entstehung sowie die Verbindungen zwischen verschiedenen supramolekularen Konstrukten und den Stand der Wissenschaft bezüglich neuer Materialien an dieser Schnittstelle.
Measurements of Decompression Wave Speed in Binary Mixtures of Carbon Dioxide and Impurities (2016)

Shock tube tests were conducted on a number of binary CO2 mixtures with N2, O2, CH4, H2, CO, and Ar impurities, from a range of initial pressures and temperatures. This paper provides examples of results from these tests. The resulting decompression wave speeds are compared with predictions made utilizing different equations of state (EOS). It was found that, for the most part (except for binaries with H2), the GERG-2008 EOS shows much better performance than the Peng–Robinson (PR) EOS. All binaries showed a very long plateau in the decompression wave speed curves. It was also shown that tangency of the fracture propagation speed curve would normally occur on the pressure plateau, and hence, the accuracy of the calculated arrest toughness for pipelines transporting these binary mixtures is highly dependent on the accuracy of the predicted plateau pressure. Again, for the most part, GERG-2008 predictions of the plateau are in good agreement with the measurements in binary mixtures with N2, O2, and CH4. An example of the determination of pipeline material toughness required to arrest ductile fracture is presented, which shows that prediction by GERG-2008 is generally more conservative and is therefore recommended. However, both GERG-2008 and PR EOS show much worse performance for the other three binaries: CO2 + H2, CO2 + CO, and CO2 + Ar, with CO2 + H2 being the worst. This is likely due to the lack of experimental data for these three binary mixtures that were used in the development of these EOS.
On the Equivalence of MMSE and IRC Receiver in MU-MIMO Systems (2011)

In order to combat the residual interference in multiuser multiple-input and multiple-output systems (MU-MIMO), a number of low-complexity interference aware type of receivers have been considered. In this letter, single layer Minimum Mean Square Error (MMSE) and Interference Rejection Combiner (IRC) are applied in MU-MIMO transmission. Based on some very simple but extremely useful matrix manipulations, their equivalence is proven analytically and demonstrated via Monte Carlo simulations.
Comparison of 1D and 2D Model Results for Selective Emitter and Interdigitated Back Contact Cells (2012)

PC2D is a circular-reference spreadsheet method to be used in conjunction with PC1D for simulating two-dimensional effects in solar cells. Both 1D and 2D models are approximate and do not perfectly describe all aspects of the cell. It is up to the user to determine what level of modeling accuracy is desired and how many resources (time, effort, and capital investment) should be expended. This paper evaluates whether or not the increased complexity of a 2D model, specifically PC2D, is merited for two different cell structures, one with only slight twodimensionality and the other with clear two-dimensional aspects – namely the Selective Emitter (SE) and Interdigitated Back Contact (IBC) cells, respectively. In the case of the SE solar cell, it is relatively simple to construct a representative 1D model. The differences between the 1D and 2D model are shown to be negligible. In the case of the IBC cell, it is more difficult to construct a representative 1D model and there are significant differences in estimated performance between the two models. Thus, for the IBC cell it is more appropriate to model the cell in 2D.
<title>Lifetime of fiber Bragg gratings under cyclic fatigue</title> (1999)

We present results on optical and mechanical stability of single-layered acrylate coated fiber Bragg gratings produced on a draw tower, and exposed to high temperature annealing and to cyclic loading. Optical stability was assessed in terms of strain response and reflectivity changes with annealing temperatures up to 400 degree(s)C. Cyclic loading of Bragg gratings with mean stresses between 2.4 GPa and 3.0 GPa was compared with predictions made by using power-law based crack growth theory with parameters obtained by dynamic tensile tests. Comparison with theory confirms predicted strength decrease and lifetime reduction.

Metasurface synthesis through multi-objective optimization aided inverse-design (2019)

Advances in design and nanofabrication are enabling the ability to realize nanophotonic structures that achieve optical functionalities not possible with conventional devices. Some of the most interesting structures being developed are based on metasurfaces comprised of sub-wavelength unit cells intelligently patterned to locally manipulate an electromagnetic wavefront in a desired way. However, designing a metasurface to achieve a specific set of desired functionalities is extremely challenging especially in the presence of coupling between unit cells, which can affect system performance and lead to unexpected optical aberrations. To overcome this challenge, designers typically employ only canonical structures (e.g., loaded-dipoles, v-antennas, split-ring resonators) to synthesize a metasurface to achieve their desired functionality. However, metadevices based on these canonical structures do not always achieve optimal performance especially when broadband and/or wide-field-of-view functionality is desired. Additionally, different material combinations as well as fabrication effects and tolerances can make the optimal unit cell topology selection difficult. Therefore, the ability to generate a diverse set of unintuitive metasurface unit cells and evaluate their electromagnetic behaviors for achieving a specific functionality is highly desirable. Moreover, doing so in an efficient and intelligent manner is extremely important in order to maintain a tractable inverse design process. To this end, we employ a custom nanoantenna unit cell topology generation routine in conjunction with robust state-of-the-art multi-objective and surrogate-assisted optimization algorithms to find optimal designs that achieve an arbitrary number of user-specified performance criteria. Finally, when paired with advanced full-wave forward solvers these design and optimization algorithms enable an efficient inverse design toolkit for high performance metasurface synthesis.

EAACI Molecular Allergology User's Guide (2016)

The availability of allergen molecules ('components') from several protein families has advanced our understanding of immunoglobulin E (IgE)-mediated responses and enabled 'component-resolved diagnosis' (CRD). The European Academy of Allergy and Clinical Immunology (EAACI) Molecular Allergology User's Guide (MAUG) provides comprehensive information on important allergens and describes the diagnostic options using CRD. Part A of the EAACI MAUG introduces allergen molecules, families, composition of extracts, databases, and diagnostic IgE, skin, and basophil tests. Singleplex and multiplex IgE assays with components improve both sensitivity for low-abundance allergens and analytical specificity; IgE to individual allergens can yield information on clinical risks and distinguish cross-reactivity from true primary sensitization. Part B discusses the clinical and molecular aspects of IgE-mediated allergies to foods (including nuts, seeds, legumes, fruits, vegetables, cereal grains, milk, egg, meat, fish, and shellfish), inhalants (pollen, mold spores, mites, and animal dander), and Hymenoptera venom. Diagnostic algorithms and short case histories provide useful information for the clinical workup of allergic individuals targeted for CRD. Part C covers protein families containing ubiquitous, highly cross-reactive panallergens from plant (lipid transfer proteins, polcalcins, PR-10, profilins) and animal sources (lipocalins, parvalbumins, serum albumins, tropomyosins) and explains their diagnostic and clinical utility. Part D lists 100 important allergen molecules. In conclusion, IgE-mediated reactions and allergic diseases, including allergic rhinoconjunctivitis, asthma, food reactions, and insect sting reactions, are discussed from a novel molecular perspective. The EAACI MAUG documents the rapid progression of molecular allergology from basic research to its integration into clinical practice, a quantum leap in the management of allergic patients.

LIE operators for compressive sensing (2014)

We consider the efficient acquisition, parameter estimation, and recovery of signal ensembles that lie on a low-dimensional manifold in a high-dimensional ambient signal space. Our particular focus is on randomized, compressive acquisition of signals from the manifold generated by the transformation of a base signal by operators from a Lie group. Such manifolds factor prominently in a number of applications, including radar and sonar array processing, camera arrays, and video processing. Leveraging the fact that Lie group manifolds admit a convenient analytical characterization, we develop new theory and algorithms for: (1) estimating the Lie operator parameters from compressive measurements, and (2) recovering the base signal from compressive measurements. We validate our approach with several of numerical simulations, including the reconstruction of an affine-transformed video sequence from compressive measurements.
Investigations Into the Application of NMS Tools to Modeling the Global Information Grid (GIG) (2005)

Abstract : This report documents our work in support of transition of the capabilities and tools developed within the Defense Advanced Research Project Agency (DARPA) Information Program Technology Office (IPTO) Network Modeling and Simulation (NMS) Program to the greater Department of Defense (DoD) community. We chose to use the efforts to design and architect the Global Information Grid (GIG) as a test case. We then identified a set of performance studies of interest to GIG engineers and architects, compared the set of tools and capabilities derived within the DARPA NMS program against the needs of these performance studies, and identified a software architecture (based upon these and related tools) for a reusable GIG simulation platform. In the process we identified a set of gaps in tool sets that require further work, i.e., capabilities software development and integration.

Generalized bounds on the crest-factor distribution of OFDM signals with applications to code design (2006)

In this paper generalized bounds on the crest-factor (CF) distribution in orthogonal frequency-division multiplexing (OFDM) transmission for both independent and dependent subcarriers are derived. Here, the latter situation represents the coded case. For independent subcarriers, a general path for bounding practical constellations is provided. Moreover, a complete characterization of their asymptotic behavior is devised and discussed. The results are shown to carry over to the spherical constellations improving on recent results. For dependent subcarriers, the focus is mainly on binary codes where bounds on the CF distribution are obtained in terms of the distance distributions and their duals. The asymptotic behavior of codes is analyzed and it is shown that the upper bound on the effective crest-factor of a large class of Bose-Chaudhuri-Hocquenghem (BCH) codes behaves asymptotically as radiclogN. Finally, two applications of the results to code design are presented: first, fixed phase shifts on the subcarriers for all codewords are used and an algorithm to calculate the phase shifts is designed. That way, it is proved that the effective CF of any binary code can be scaled to be of order radiclogN for large N without sacrificing on rate. Furthermore, the same approach is applied to calculation of the phases of redundant subcarriers for each codeword. It is shown by simulations that the values can be effectively chosen so that the CF is significantly reduced with nonexponential complexity
Tilted bilayer membranes as simple transmission quarter-wave retardation plates (2001)

A tilted bilayer membrane, which consists of two thin films of transparent optically isotropic materials of different refractive indices, can function as a transmission quarter-wave retarder (QWR) at a high angle of incidence. A specific design using a cryolite-Si membrane in the infrared is presented, and its tolerances to small shifts of wavelength, incidence angle, and film thickness errors are discussed. Some designs provide a dual QWR in transmission and reflection. Such devices provide simple linear-to-circular (and circular-to-linear) polarization transformers. Bilayer eighth-wave retarders without diattenuation are also introduced.
