Improved Staggered Through Silicon Via Inductors for RF and Power Applications (2018)

Inductors are important components for RF and power applications, in which high quality factors and large inductances with minimum footprints are critical. Compared to conventional 2D spiral inductors, 3D TSV inductors can achieve higher inductance values with smaller footprints. This paper focuses on the optimization of high-Q and high-density TSV inductors on lossy Si substrates. In a first step, technology aspects of the optimization will be discussed. Subsequently, a novel concept to improve the TSV inductor performance, based on a polymer wall as the shielding technique for the 3D TSV inductor will be introduced. Furthermore, to minimize the footprint and increase the inductor density, staggered TSV inductor configurations will be assessed. Finally, inductors with magnetic cores and air gaps show promising results for power application in the MHz frequency range.
Topological Mapping with Multiple Visual Manifolds (2005)

We address the problem of building topological maps in visual space for robot navigation. The nodes of our topological maps consist of clusters along manifolds, and we propose an unsupervised learning algorithm that automatically constructs these manifolds -the user need only specify the desired number of clusters and the minimum number of images per cluster. This spectral clustering like framework allows each cluster to optimize a separate set of clustering parameters, and we demonstrate empirically that this flexibility can significantly improve clustering results. We further propose a framework for servoing the robot in our manifold space, which would allow the robot to navigate from any point on one manifold (topological node) to any specified point on a second manifold. Finally, we present experimental results on indoor and outdoor image sequences demonstrating the efficacy of the proposed algorithm.
Inverse Emulsion Polymerization of Acrylamide in Near-Critical and Supercritical Continuous Phases (1989)

The inverse microemulsion polymerization of water-soluble acrylamide monomers within near-critical and supercritical alkane continuous phase provides a potential route for production of polymers with novel physical properties and at high reaction rates. In order to define conditions for a model polymerization process, the phase behavior of a nonionic surfactant/acrylamide/water system in near- and supercritical mixtures of ethane and propane was examined. Results show that in mixtures of ethane and propane the continuous-phase density determines the phase behavior. Results also show that acrylamide acts as a co-surfactant with C16E2/C12E4 (Brij) surfactant blend used for these experiments. Surprisingly, increasing the total dispersed-phase volume fraction lowers the density (and consequently pressure) required to form a stable microemulsion. Dynamic light scattering results suggest the presence of strong micelle-micelle interactions, or clustering, the extent of which increases rapidly as the phase boundary is approached. Initial polymerization results indicate possible dependencies of both the polymerization rate and the molecular weight on continuous-phase density and/or the degree of micelle-micelle clustering, suggesting that the monomer may not be as accessible to a growing chain as in a classical emulsion polymerization.
Conversions in Laparoscopic Renal Surgery: Causes and Outcomes (2011)

Rate of conversion to an open procedure is significantly impacted by surgical indication, specimen size, and surgical technique. Any conversion is associated with an increased perioperative morbidity.
Status of the NASA/Virginia Tech Benchmark Experiments for CFD Validation (2020)

A new study of low Mach number, high Reynolds number flow of a plane turbulent boundary layer over wall-mounted bumps is underway. The goal is to produce detailed experimental data sets of smooth wall flows with various levels of separation that, for the first time, meet the most exacting requirements of CFD validation as per Oberkamp and Smith \cite{oberkampf2017assessment}. To attain this goal, an intensive research program, collaborative with NASA Langley Research Center, is underway that brings together experts in experiments, computations and CFD validation. This effort involves detailed measurements and calculations needed for full uncertainty quantification, experimental configuration design, and extensive documentation of the flow boundary conditions and boundary condition sensitivities. In this paper, an overview of the status of the project is presented, including details of the experimental configuration and key findings that establish the configuration as well suited for the needs of turbulence modeling validation for smooth body separation.
Controllable Dynamic Multi-Task Architectures (2022)

Multi-task learning commonly encounters competition for resources among tasks, specifically when model capac-ity is limited. This challenge motivates models which al-low control over the relative importance of tasks and total compute cost during inference time. In this work, we pro-pose such a controllable multi-task network that dynami-cally adjusts its architecture and weights to match the de-sired task preference as well as the resource constraints. In contrast to the existing dynamic multi-task approaches that adjust only the weights within a fixed architecture, our approach affords the flexibility to dynamically control the total computational cost and match the user-preferred task importance better. We propose a disentangled training of two hype rnetwo rks, by exploiting task affinity and a novel branching regularized loss, to take input prefer-ences and accordingly predict tree-structured models with adapted weights. Experiments on three multi-task bench-marks, namely PASCAL-Context, NYU-v2, and CIFAR-100, show the efficacy of our approach. Project page is available at https://www.nec-labs.com/-mas/DYMU.
Kinetics of formation of a macroscale binary Coulombic material (2023)

This paper describes the formation kinetics of a two-dimensional, binary Coulombic material. The material is formed by mechanically agitating millimeter-sized nylon and polytetrafluoroethylene (PTFE) beads that tribocharge positively and negatively, respectively. The authors alter the relative number of nylon and PTFE beads, without changing their combined total. They discover a common transient structure that does not depend on the relative ratio of nylon and PTFE beads, reveal a structure transition driven by the minimization of Coulombic energy, and provide insights for the rational design of materials.
In vitro sensitivity of antifungal agents. (1989)

In vitro sensitivity tests indicated econazole to be the best drug against all 30 isolates of Trichophyton species followed by miconazole, clotrimazole and tolnaftate. Econazole inhibited the growth of all isolates of Trichophyton species in low concentrations of 2-4 micrograms/ml except one isolate of T. rubrum which was inhibited by a concentration of 8 micrograms/ml. Miconazole was also able to inhibit growth of 73.3 per cent isolates of Trichophyton species in low concentrations of 2-4 micrograms/ml. On the other hand, only 13.3 per cent isolates were found sensitive at 2-4 micrograms/ml concentration to tolnaftate and clotrimazole. Relative resistance was encountered by 7 isolates (23.3%) to tolnaftate and 2 isolates (6.6%) to clotrimazole. Isolates of T. tonsurans were resistant to tolnaftate, whereas, the isolate of T. mentagrophytes was sensitive to all the drugs in low concentrations.
Structural and Pharmacological Characterization of Novel Potent and Selective Monoclonal Antibody Antagonists of Glucose-dependent Insulinotropic Polypeptide Receptor (2013)

Glucose-dependent insulinotropic polypeptide (GIP) is an endogenous hormonal factor (incretin) that, upon binding to its receptor (GIPr; a class B G-protein-coupled receptor), stimulates insulin secretion by beta cells in the pancreas. There has been a lack of potent inhibitors of the GIPr with prolonged in vivo exposure to support studies on GIP biology. Here we describe the generation of an antagonizing antibody to the GIPr, using phage and ribosome display libraries. Gipg013 is a specific competitive antagonist with equally high potencies to mouse, rat, dog, and human GIP receptors with a Ki of 7 nm for the human GIPr. Gipg013 antagonizes the GIP receptor and inhibits GIP-induced insulin secretion in vitro and in vivo. A crystal structure of Gipg013 Fab in complex with the human GIPr extracellular domain (ECD) shows that the antibody binds through a series of hydrogen bonds from the complementarity-determining regions of Gipg013 Fab to the N-terminal α-helix of GIPr ECD as well as to residues around its highly conserved glucagon receptor subfamily recognition fold. The antibody epitope overlaps with the GIP binding site on the GIPr ECD, ensuring competitive antagonism of the receptor. This well characterized antagonizing antibody to the GIPr will be useful as a tool to further understand the biological roles of GIP.
Anisotropic Correction of Beam-induced Motion for Improved Single-particle Electron Cryo-microscopy (2016)

Abstract Correction of electron beam-induced sample motion is one of the major factors contributing to the recent resolution breakthroughs in cryo-electron microscopy. Improving the accuracy and efficiency of motion correction can lead to further resolution improvement. Based on observations that the electron beam induces doming of the thin vitreous ice layer, we developed an algorithm to correct anisotropic image motion at the single pixel level across the whole frame, suitable for both single particle and tomographic images. Iterative, patch-based motion detection is combined with spatial and temporal constraints and dose weighting. The multi-GPU accelerated program, MotionCor2, is sufficiently fast to keep up with automated data collection. The result is an exceptionally robust strategy that can work on a wide range of data sets, including those very close to focus or with very short integration times, obviating the need for particle polishing. Application significantly improves Thon ring quality and 3D reconstruction resolution.
Unclassified renal cell carcinoma: clinical features and prognostic impact of a new histological subtype. (2002)

Unclassified renal cell carcinoma is associated with distinct and highly aggressive biological behavior, and poor clinical outcome. Whenever feasible, immunotherapy with nephrectomy is warranted.
Stability of transmitter cooperation over a multiple access channel (2012)

Cooperation between nodes has become increasingly necessary to mitigate interference in modern wireless networks. The question of whether cooperation is fair and stable and whether all rational nodes have a sufficiently large incentive to cooperate is unknown even for simple networks. This paper addresses the stability of cooperation between rational transmitters (TXs) signaling over a multiple access channel (MAC) using the framework of cooperation game theory. Using the sum rate as the utility of each coalition of TXs, the stability of the grand coalition is examined by evaluating the core of the TX game cooperation game in partition form, a game model in which the utility of a coalition depends on TXs external to the coalition. The non-emptiness of the core implies that there exists a feasible division of utility such that no smaller coalition of TXs has an incentive to deviate from the grand coalition. For a single user decoding (SUD) receiver, the cooperation is shown to be stable in the high SNR and low SNR regimes while for a successive interference cancelling (SIC) receiver with fixed decoding order, cooperation is stable only in the low SNR regime.
Interpolation for nonlinear Retinex-type algorithms (2007)

In this paper we propose a method to speed up Retinex-type algorithms, consisting of a computationally intensive nonlinear
illumination estimation module followed by a relatively simple manipulation module. Speed up is obtained by way
of computing the illumination on a sub-sampled image. The challenge is to interpolate a piece-wise smooth low
resolution image. We present and analyze the trade of between two types of interpolation methods. On one hand, regular
illumination interpolation, which preserves the Retinex-type output quality, however may result in artifacts. On the other
hand a detail preserving interpolation which removes artifacts, however may compromise the output quality.
Understanding Process Impact of Hole Traps and NBTI in HKMG p-MOSFETs Using Measurements and Atomistic Simulations (2013)

The impact of the gate insulator process on interlayer (IL) hole traps in IL/high-K dual-layer p-MOSFET gate-stack is studied by physical and electrical measurements along with atomistic simulations. Processes that lead to higher concentrations of Hf and N in IL, measured by angle-resolved X-ray photoelectron spectroscopy, result in higher IL hole traps measured by flicker noise in prestress and verified by atomistic simulations. The influence of these process induced preexisting IL hole traps on parametric degradation of p-MOSFETs during Negative bias temperature instability (NBTI) stress is studied. The mechanism responsible for superior NBTI of thermal IL stack, having lower Hf and N content in the IL as compared with Chem-Ox IL stack, is explained.
Hydrothermal Synthesis of Delafossite-Type Oxides (2005)

The syntheses of copper and silver delafossite-type oxides from their constituent binary metal oxides, oxide hydroxides and hydroxides, by low temperature (<210 °C) and low pressure (<20 atm) hydrothermal reactions are described. Particular emphasis is placed on how the acid−base character of a constituent oxide determines its solubility and therefore whether a particular delafossite-type oxide can be synthesized, a strategy utilized by geologists and mineralogists to understand the conditions necessary for the synthesis of various minerals. Thus, the geochemical and corrosion science literature are shown to be useful in understanding the reaction conditions required for the syntheses of delafossite-type oxides and the relationship between reactant metal oxide acid−base character, solubility, aqueous speciation, and product formation. Manipulation of the key parameters, temperature, pressure, pH, and reactant solubility, results in broad families of phase-pure delafossite-type oxides in moderate to high yields for copper, CuBO2 (B = Al, Sc, Cr, Mn, Fe, Co, Ga, and Rh), and silver, AgBO2 (B = Al, Sc, Fe, Co, Ni, Ga, Rh, In, and Tl).
Morphotypic analysis and classification of bacteria and bacterial colonies using laser light-scattering, pattern recognition, and machine-learning system (2009)

Light scattering is one of the most fundamental optical processes whereby electromagnetic waves are forced to deviate from a straight trajectory by non-uniformities in the medium that they traverse. This presentation summarizes our recent research on application of light-scatter measurements paired with machine learning and pattern recognition methodologies for label-free classification of bioparticles. Two separate examples of light scatter-based techniques are discussed: forward-scatter measurements of bacterial colonies in an imaging system, and flow cytometry measurements of scatter signals formed by individual bacterial particles. Recently, we have reported a first practical implementation of a system capable of label-free classification and recognition of pathogenic species of <i>Listeria</i>, <i>Salmonella, Vibrio, Staphylococcus, </i>and <i>E. coli</i> using forward-scatter patterns produced by bacterial colonies irradiated with laser light. Individual bacteria in flow also form complex patterns dependent on particle size, shape, refraction index, density, and morphology. Although commercial flow cytometers allow scatter measurement at two angles this rudimentary approach cannot be used to separate populations of bioparticles of similar shape, size, or structure. The custom-built system used in the presented work collects axial light-loss and scatter signals at five carefully chosen angles. Experimental results obtained from colony scanner, as well from the extended cytometry instrument, were used to train the pattern-recognition algorithm. The results demonstrate that information provided by scatter alone may be sufficient to recognize various bioparticles with 90-99% success rate, both in flow and in imaging systems.
Optimizing Antigen Cocktails for Detection ofMycobacterium bovisin Herds with Different Prevalences of Bovine Tuberculosis: ESAT6-CFP10 Mixture Shows Optimal Sensitivity and Specificity (2006)

Bovine tuberculosis is a major problem in many countries; hence, new and better diagnostic tools are urgently needed. In this work, we have tested ESAT6, CFP10, PE13, PE5, MPB70, TB10.4, and TB27.4 for their potentials as diagnostic markers in field animals from Northern Ireland, Mexico, and Argentina, regions with low, medium, and high prevalences of bovine tuberculosis, respectively. At all three sites, ESAT6 and CFP10 were superior diagnostic antigens, while their combination performed even better at the two sites where the combination was tested, providing the best coverage for the detection of diseased populations. The high sensitivity in the skin test reactor groups, combined with the high specificity in the tuberculosis-free groups, indicated that a diagnosis could correctly be made for 85% of the infected animals, based on their responses to these two antigens. Furthermore, TB10.4, PE13, and PE5 have the potential to supplement ESAT6 and CFP10 in a future five-component diagnostic cocktail.

Statistical measurement of random telegraph noise and its impact in scaled-down high-&#x03BA;/metal-gate MOSFETs (2012)

This paper presents results of statistical analysis of RTN in highly scaled HKMG FETs. A robust algorithm to extract multiple-trap RTN is proposed and applied to show that RTN can cause serious variation even when HKMG and undoped channel are introduced. We further focus on hysteretic behavior caused by RTN with time constants much longer than the circuit timescale. This reveals that RTN also induces novel instabilities such as short-term BTI and logic delay uncertainty. Extraction of RTN in SRAM arrays is also presented to discuss its impact on operational stability.
Plasma facilitated delivery of DNA to skin (2009)

Non-viral delivery of cell-impermeant drugs and DNA in vivo has traditionally relied upon either chemical or physical stress applied directly to target tissues. Physical methods typically use contact between an applicator, or electrode, and the target tissue and may involve patient discomfort. To overcome contact-dependent limitations of such delivery methodologies, an atmospheric helium plasma source was developed to deposit plasma products onto localized treatment sites. Experiments performed in murine skin showed that samples injected with plasmid DNA encoding luciferase and treated with plasma demonstrated increased levels of expression relative to skin samples that received injections of DNA alone. Increased response relative to injection alone was observed when either positive or negative voltage was used to generate the helium plasma. Quantitative results over a 26-day follow-up period showed that luciferase levels as high as 19-fold greater than the levels obtained by DNA injection alone could be achieved. These findings indicate that plasmas may compete with other physical delivery methodologies when skin is the target tissue.

Effect of Additives on the Direct Synthesis of L10-FePt Nanoparticles by Polyol Process (2005)

Partially ordered L10-FePt nanoparticles synthesized in tetraethylene glycol by using polyol process is mostly polycrystalline in nature. In this paper, we attempted the preparation of single crystal L10-FePt nanoparticles by introducing nucleating and complexing agents during the synthesis. Though the synthesis of L10-FePt particles with constant physical properties was possible by using hexachloroplatinate (H2PtCl6) as the nucleating agent, particles remained polycrystalline in nature. However, when carboxylic acid was used along with H2PtCl6 FePt nanoparticles with more than 50 % ordering was realized under the optimum experimental conditions of Fe:Pt initial mole ratio of 52.5:47.5, 1 at% H2PtCl6 and five equivalent weight of Fe of carboxylic acid. The superlattice reflection lines of (001) and (110) in XRD pattern and the sextets from the Mossbauer spectroscopy at room temperature confirmed the presence of L10 phase. The coercivity and anisotropy field of these particles were 5. 6 kOe and more than 40 kOe, respectively.
