MDG (2007)

Dense deployments of WLANs suffer from increased interference and as a result, reduced capacity. There are three main functions used to improve the overall network capacity: a) intelligent frequency allocation across APs, b) load-balancing of user affiliations across APs, and c) adaptive power-control for each AP. Several algorithms have been proposed in each category, but so far, their evaluation has been limited to: (a) each approach in isolation and, (b)simulations or small-scale testbeds. In this paper, we ask the question: what is the best way to combine these different functions? Our focus is to fully explore the interdependencies between the three functions in order to understand when and how to deploy them on a network. We follow a measurement-driven study to quantify the effects of three previously proposed optimization schemes (one for each category) on a relatively large testbed and in many different scenarios. Surprisingly, we find that blindly applying all the three optimization schemes is not always preferable; it can sometimes degrade the performance by as much as 24% compared to using only two of the schemes. We discover that there are explicit conditions that are conducive for applying specific combinations of the optimization schemes. We capture those conditions within a comprehensive framework, which we call MDG (Measurement-Driven Guidelines). While we derive suchguidelines based on measurements on one experimental testbed, we test their applicability and efficacy on a second testbed in a different location. We show that our framework improves network capacity consistently acrossboth testbeds, with improvements ranging from 22% to 142% with 802.11a, and 103% to 274% with 802.11g.

Activation of MMPs and possible ECM disruption represent novel mechanisms of FOXO3a-mediated apoptosis in ECs.
Mathematical Model for a Parabolic Cylinder Reflector (1972)

A mathematical model is developed for an ideal parabolic cylinder reflector driven by a line source coincident with its focal line. The parabolic cylinder is assumed to be infinite in length but of finite width. This two-dimensional model enables one to quickly ascertain the major features of the farfield when given only the acoustic size of the aperture, the focal length, and the type of reflector (rigid or pressure release). The model, which utilizes a quasigeometrlcal acoustics approach, is based on the following two assumptions: (1) there exists a definite shadow zone behind the reflector, and (2) the field “within” the reflector depends primarily on the boundary conditions on the inside surface of the reflector. By means of these assumptions the problem is reduced to solving a boundary value problem where the radiating surface is an infinite circular cylinder. The reduced problem is then solved using the fast Fourier transform algorithm. The results are compared with available experimental data.
Efficient on-chip global interconnects (2004)

We present circuits for a high-efficiency low-swing interconnect scheme suitable for the Smart Memories reconfigurable architecture. By using a separate supply, global clocking, and differential signaling, we reduce design complexity; and by using overdrive circuits, equalization techniques, and sense-amplifiers we retain high performance. A testchip built in a 1.8 V 0.18-/spl mu/m technology consumed <1pJ/bit for a 10 mm bus at 1 GHz, a power savings over full-swing signaling of up to 10 x, and demonstrated amplifier input offset voltages of under 100 mV.
Realization of 2D Crystalline Metal Nitrides via Selective Atomic Substitution (2019)

Two-dimensional (2D) transition metal nitrides (TMNs) are new members in the 2D materials family with a wide range of applications. Particularly, highly crystalline and large area thin films of TMNs are potentially promising for applications in electronic and optoelectronic devices; however, the synthesis of such TMNs has not yet been achieved. Here, we report the synthesis of few-nanometer thin Mo5N6 crystals with large area and high quality via in situ chemical conversion of layered MoS2 crystals. The structure and quality of the ultrathin Mo5N6 crystal are confirmed using transmission electron microscopy, Raman spectroscopy and X-ray photoelectron spectroscopy. The large lateral dimensions of Mo5N6 crystals are inherited from the MoS2 crystals that are used for the conversion. Atomic force microscopy characterization reveals the thickness of Mo5N6 crystals is reduced to about 1/3 of the MoS2 crystal. Electrical measurements show the obtained Mo5N6 samples are metallic with high electrical conductivity (~ 100 Ω sq-1), which is comparable to graphene. The versatility of this general approach is demonstrated by expanding the method to synthesize W5N6 and TiN. Our strategy offers a new direction for preparing 2D TMNs with desirable characteristics, opening a door for studying fundamental physics and facilitating the development of next generation electronics.
Transcriptional control by two interacting regulatory proteins: identification of the PtxS binding site at PtxR (2013)

The PtxS and PtxR regulators control the expression of the glucose dehydrogenase genes from the Pgad promoter in Pseudomonas aeruginosa. These regulators bind to their cognate operators, that are separated by ∼50 nt, within the promoter region and interact with each other creating a DNA-loop that prevents RNA polymerase promoter access. Binding of the 2-ketogluconate effector to PtxS caused PtxS/PtxR complex dissociation and led to the dissolution of the repression loop facilitating the entry of the RNA polymerase and enabling the transcription of the gad gene. We have identified a hydrophobic surface patch on the PtxR putative surface that was hypothesized to correspond to the binding site for PtxS. Two surface-exposed residues in this patch, V173 and W269, were replaced by alanine. Isothermal titration calorimetry assays showed that PtxS does not interact with the mutant variants of PtxR. Electrophoretic mobility shift assay and DNAase I footprinting assays proved that both regulators bind to their target operators and that failure to interact with each other prevented the formation of the DNA-loop. In vitro transcription showed that PtxS per se is sufficient to inhibit transcription from the Pgad promoter, but that affinity of PtxS for its effector is modulated by PtxR.
Miniaturization and Optimization of RF SAW Filter Using Wafer Level Packaging Technology (2007)

In this paper, we describes the wafer level surface acoustic wave (SAW) filter package, 1.0times0.8 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> , which is applicable for radio frequency (RF) stage in mobile phones. The SAW filter is reduced in size and thickness by using a 4" wafer level package process technique. The technique uses interconnection via and LiTaO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> (LT)-LiTaO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> (LT) wafer bonding structure. The interconnection via is formed through LT wafer by using sand blasting or laser drilling method. The AuSn eutectic bonding enables the connection of the signal pad on the SAW chip, with gold metallized LT wafer package. This eutectic bonding ensures that the SAW chip is protected mechanically and connected electrically, with the package. In order to simulate and optimize the structure and characteristics of wafer level SAW filter package, we used HFSS and ADS software. Frequency responses of measurement and simulation are compared with wafer level SAW filter package. The results of reliability tests for wafer level SAW filter package will be discussed.
Cellular and Molecular Consequences of Calcineurin Aα Gene Deletion (2007)

Here we briefly review our studies that have unraveled an important role for the calcium- and calmodulin-sensitive enzyme calcineurin (CN) in bone remodeling. We find that the genetic deletion of the calcineurin Aalpha isoform results in osteoporosis, which is recapitulated in humans following calcineurin inhibitor therapy widely used after solid organ transplantation. Mechanistically, however, while both calcineurin inhibitors cyclosporine and tacrolimus initially stimulate osteoclastic bone resorption in humans, the predominant feature in the CNAalpha null mouse is a profound reduction in bone formation. We speculate that the so-called "calcineurin inhibitors" may interact with molecules other than calcineurin. The clinical relevance of these observations is explored.
A grid voltage sensor-less operational approach of interconnecting distributed generating source based inverter to unbalanced generalized three-phase grid together with local load at PCC (2012)

In this paper, a novel grid voltage sensor-less operation of the generalized three-phase grid connected distributed generating source based inverter operation is proposed. The method also takes into consideration the presence of a local load at the point of common coupling (PCC). In the proposed method, the same inverter current controller is used to estimate the grid voltages and to control the inverter to achieve the control on grid active and reactive power flow along with the sinusoidal grid currents. The proposed system is implemented directly in the a-b-c frame and Spatial Repetitive Controller (SRC) is used as the main control algorithm of the proposed scheme. Experimental results are provided to show the efficacy of the proposed sensorless control methodology.

A Framework for Automatic Debugging of Functional and Degradation Failures (2016)

Software diagnosis is a particularly challenging problem for modern systems, which may consist of dozens, if not hundreds, of components computing on concurrent and potentially distributed platforms, and using infrastructure and services built by many organizations. We propose a framework that generalizes state-of-the-art classical reasoning-based fault diagnosis which tolerates observation uncertainty and addresses degradation of quality of service. Empirical evaluation involving 27000 highly realistic synthetic scenarios demonstrates an average accuracy improvement of 20% (with 99% statistical significance) which is considerable in the domain of Software Fault Localization (SFL). We measure the improvement in accuracy on well-established SFL performance metrics.
Graphenic Carbon-Silicon Contacts for Reliability Improvement of\n Metal-Silicon Junctions (2016)

Contact resistance and thermal degradation of metal-silicon contacts are\nchallenges in nanoscale CMOS as well as in power device applications. Titanium\nsilicide (TiSi) contacts are commonly used metal-silicon contacts, but are\nknown to diffuse into the active region under high current stress. In this\npaper we show that a graphenic carbon (C) contact deposited on n-type silicon\n(C-Si) by CVD, has the same low Schottky barrier height of 0.45 eV as TiSi, but\na much improved reliability against high current stress. The C-Si contact is\nover 100 million times more stable against high current stress pulses than the\nconventionally used TiSi junction. The C-Si contact properties even show\npromise to establish an ultra-low, high temperature stable contact resistance.\nThe finding has important consequences for the enhancement of reliability in\npower devices as well as in Schottky-diodes and electrical contacts to silicon\nin general.\n

Analysis of common-mode noise on on-chip differential lines through stochastic modeling of parameter variability (2012)

In this contribution a novel stochastic modeling strategy to analyze the influence of parameter variability on differential signaling over on-chip interconnects is presented. The method starts from an accurate computation of the differential line's per unit of length transmission line parameters, adopts a parameterized macromodeling scheme, and invokes the so-called stochastic Galerkin method (SGM). Parameter variability of the line itself and of the terminations are studied and compared to a traditional Monte Carlo (MC) approach, as such demonstrating excellent accuracy and efficiency of the proposed new technique. For the first time, an SGM is constructed for and applied to differential on-chip interconnects, and it is illustrated that this novel stochastic modeling strategy is very well suited to analyze common-mode noise induced by random imbalance of the line's terminations.
Photophysics of GaN single-photon emitters in the visible spectral range (2018)

© 2018 American Physical Society. In this work, we present a detailed photophysical analysis of recently discovered, optically stable single-photon emitters (SPEs) in gallium nitride (GaN). Temperature-resolved photoluminescence measurements reveal that the emission lines at 4 K are three orders of magnitude broader than the transform-limited width expected from excited-state lifetime measurements. The broadening is ascribed to ultrafast spectral diffusion. The photophysical study on several emitters at room temperature (RT) reveals an average brightness of (427±215)kCounts/s. Finally, polarization measurements from 14 emitters are used to determine visibility as well as dipole orientation of defect systems within the GaN crystal. Our results underpin some of the fundamental properties of SPEs in GaN both at cryogenic and RT, and define the benchmark for future work in GaN-based single-photon technologies.

ON-state retention of Atom Switch eNVM for IoT/AI Inference Solution (2020)

An ON-state retention of a 40nm-node atom switch embedded nonvolatile memory (eNVM) has been carefully investigated for IoT/AI inference solution. Based on ON-conductance (G <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> ) tuning model of atom switch, one order of magnitude lower programming power is achieved while keeping the same G <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">on</sub> .

Safety of multiple, submucosal inoculations of a live attenuated strangles vaccine in pregnant mares (2009)

Summary A live attenuated vaccine against Streptococcus equi was administered submucosally in the upper lip to 224 pregnant and healthy mares to evaluate its safety. After a primary immunisation the mares were inoculated every 3 months until foaling. As control group, 206 mares of the same breeding farm were administered the solvent of the vaccine submucosally. None of the 430 mares presented any clinical evidence of strangles and neither local nor systemic reactions to vaccination were noticed. There was no association between abortion and vaccination. Furthermore no case of S. equi infection was revealed at post mortem examinations of aborted foals.
Preparation of YBa/sub 2/Cu/sub 3/O/sub 7/ powders by molten salt route (1989)

Superconducting YBa/sub 2/Cu/sub 3/O/sub 7/ powders were prepared by using a molten-salt process. Superconducting powders were obtained by heating the molten salt to first solidify, and then to decompose into oxide form. The precursor from copper acetate salt underwent a pyrophoric reaction upon heating while that from copper nitrate required external heating for decomposition. Powders from copper acetate were large ( approximately 10 mu m) and highly porous.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Retro-modelling of a dual resonant applicator and accurate dielectric properties of liquid water from −20 °C to +100 °C (2007)

A critical analysis is made of literature reports on the dielectric properties of pure water from liquid water supercooled at −20 ◦C, to +100 ◦C, in principle in the frequency range 0 to 3 GHz. Measurements using completemulti-step numerical modelling of a dual resonant cavity at about 920 MHz and 2230 MHz are presented. The measured data at about +20 ◦C are used as reference for the calculation of data at other temperatures. Due to the high resolution and considerations of various error sources, the resultingaccuracy becomes high and allows the construction of improved empiricalformulae for the Debye relaxation behaviour.
Privacy-preserving search for chemical compound databases (2015)

Abstract Background Searching for similar compounds in a database is the most important process for in-silico drug screening. Since a query compound is an important starting point for the new drug, a query holder, who is afraid of the query being monitored by the database server, usually downloads all the records in the database and uses them in a closed network. However, a serious dilemma arises when the database holder also wants to output no information except for the search results, and such a dilemma prevents the use of many important data resources. Results In order to overcome this dilemma, we developed a novel cryptographic protocol that enables database searching while keeping both the query holder’s privacy and database holder’s privacy. Generally, the application of cryptographic techniques to practical problems is difficult because versatile techniques are computationally expensive while computationally inexpensive techniques can perform only trivial computation tasks. In this study, our protocol is successfully built only from an additive-homomorphic cryptosystem, which allows only addition performed on encrypted values but is computationally efficient compared with versatile techniques such as general purpose multi-party computation. In an experiment searching ChEMBL, which consists of more than 1,200,000 compounds, the proposed method was 36,900 times faster in CPU time and 12,000 times as efficient in communication size compared with general purpose multi-party computation. Conclusion We proposed a novel privacy-preserving protocol for searching chemical compound databases. The proposed method, easily scaling for large-scale databases, may help to accelerate drug discovery research by making full use of unused but valuable data that includes sensitive information.
Semimonolithic Nd:YAG ring resonator for generating cw single-frequency output at 106 μm (1995)

We report 2.1 W of unidirectional single-frequency laser output from a novel Nd:YAG ring laser longitudinally pumped by a laser diode bar. The resonator requires only a single discrete optic and magnet, in addition to the laser medium, for stable multiwatt single-frequency operation. Undoped YAG is diffusion bonded to the Nd:YAG laser crystal at the pump face to eliminate residual spatial hole burning and improve thermal conductivity. This new laser design can be scaled to higher powers through more facile diode access and is useful for cw intracavity doubling.
Two-Dimensional Sum-Frequency Generation Reveals Structure and Dynamics of a Surface-Bound Peptide (2013)

Surface-bound polypeptides and proteins are increasingly used to functionalize inorganic interfaces such as electrodes, but their structural characterization is exceedingly difficult with standard technologies. In this paper, we report the first two-dimensional sum-frequency generation (2D SFG) spectra of a peptide monolayer, which are collected by adding a mid-IR pulse shaper to a standard femtosecond SFG spectrometer. On a gold surface, standard FTIR spectroscopy is inconclusive about the peptide structure because of solvation-induced frequency shifts, but the 2D line shapes, anharmonic shifts, and lifetimes obtained from 2D SFG reveal that the peptide is largely α-helical and upright. Random coil residues are also observed, which do not themselves appear in SFG spectra due to their isotropic structural distribution, but which still absorb infrared light and so can be detected by cross-peaks in 2D SFG spectra. We discuss these results in the context of peptide design. Because of the similar way in which the spectra are collected, these 2D SFG spectra can be directly compared to 2D IR spectra, thereby enabling structural interpretations of surface-bound peptides and biomolecules based on the well-studied structure/2D IR spectra relationships established from soluble proteins.
Automatic Mining of Human Activity Attributes from Weblogs (2010)

In this paper, we define an activity by five basic attributes: actor, action, object, time and location. The goal of this paper is to describe a method to automatically extract all attributes in each sentence retrieved from Japanese weblogs. Previous work had some limitations, such as high setup cost, inability of extracting all attributes, limitation on the types of sentences that can be handled, and insufficient consideration of interdependency among attributes. To resolve these problems, this paper proposes a novel approach that uses conditional random fields and self-supervised learning. This approach treats the activity extraction as a sequence labeling problem, and has advantages such as domain-independence, scalability, and does not require any hand-tagged data. Since it is unnecessary to fix the positions and the number of the attributes in activity sentences, this approach can extract all attributes by making only a single pass over its corpus. Additionally, by converting to simpler sentences, the proposed approach can deal with complex sentences retrieved from Japanese weblogs. In an experiment, this approach achieves high precision (activity: 88.87%, attributes: over 90%).
