Scrambled Soboĺ sequences via permutation (2009)

The Soboĺ sequence [USSR Comput. Math. and Phy. 7: 86–112, 1967, USSR Comput. Math. and Phy. 16: 236–242, 1976] is one of the standard quasirandom sequences, and is widely used in Q uasi- M onte C arlo (QMC) applications. QMC methods are a variant of ordinary M onte C arlo (MC) methods that employ highly uniform quasirandom numbers in place of the pseudorandom numbers used in ordinary M onte C arlo (MC) [Caflisch, Acta Numerica 7: 1–49, 1998]. The error of MC methods is asymptotically , where N is the number of samples, while QMC methods can have an error bound which behaves as well as O ((log N ) s N –1 ), for s -dimensional problems. The common practice in MC of using a predetermined error criterion as a deterministic termination condition, is almost impossible to achieve in QMC without extra technology. In order to provide such dynamic error estimates for QMC methods, several researchers [Owen, Randomly permuted (t, m, s)-nets and (t, s)-sequences, 1995, Tezuka, Uniform Random Numbers, Theory and Practice, Kluwer Academic Publishers, 1995] proposed the use of R andomized QMC (RQMC) methods, where randomness can be brought to bear on quasirandom sequences through scrambling and other related randomization techniques [Chi and Lorenzo, A Parallel Cellular Automata Model to Forecast the Effects of Urban Growth in North Florida, 2007, Chi and Mascagni, Efficient Generation of Parallel Quasirandom Sequences via Scrambling, 2007, Vandewoestyne, Chi, Mascagni and Cools, An Empirical Investigation of Different Scrambling Methods for Faure Sequences, 2007]. Besides providing practical error estimates, another byproduct of scrambled quasirandom numbers is that they furnish a natural way to generate quasirandom numbers in parallel and distributed applications. In this paper, we propose a new algorithm for scrambling the Soboĺ sequence based on the permutation (scrambling) of several groups of binary digits from the individual Soboĺ numbers. Most of the current scrambling methods either randomize a single digit at each iteration, or randomize a group of digits through linear operations. In contrast, our multiple-digit scrambling is efficient and fast because it permutes small groups of digits. We implemented this new Soboĺ scrambling algorithm in the software context of the well-known Scalable P arallel R andom N umber G enerators (SPRNG) library [Mascagni and Srinivasan, ACM Transactions on Mathematical Software 26: 436–461, 2000, Mascagni, Scalable Parallel Random Number Gernerators Library (SPRNG)] library.
Interleaved Resource Mapping for Autonomous Device-to-Device Discovery in Public Safety LTE (2017)

Device-to-device (D2D) discovery is an important function for public safety long term evolution (PS-LTE) to detect user equipment (UE) located in proximity. When many UEs are gathered at a disaster site or an incident command post, in-band emission (IBE) of discovery signals can cause significant interference resulting in discovery errors. In order to reduce the effect of IBE, a radio resource mapping method is proposed for autonomous D2D discovery in a PS-LTE system configured to repeatedly transmit discovery signals over different subframes. The proposed method interleaves discovery resources so that retransmission on resources with a certain frequency gap follows transmission on adjacent resources. Simulation results revealed that the proposed method takes 10% less time to detect UEs than a conventional method does.
Five New Oligostilbenes with One or Two Dihydrofurans from the Stem Bark of Vatica rassak (2001)

From the stem bark of Vatica rassak, five new stilbenoids (vaticanols E, F and vaticasides A-C) were isolated.The structures including the relative configuration were established on the basis of spectroscopic analysis.Plants belonging to the family Dipeterocarpaceae are known to abundant source of stilbenoids. 1, 2 Various biological effects such as chemopreventive, 3 anti-inflammatory activity, 4 and inhibitory activity of histamine release 5 and gastric ATPase 6 have been recently found in the stilbene derivatives.Stilbenoids are then regarded as useful candidates for drug development.In continuation of our phytochemical studies [7][8][9][10][11] of Dipterocarpaceous plants oriented to search for biological active principles, the structures of stilbenoids in some plants of Hopea, 7 Vatica, 8, 9 and Shorea 10, 11 were characterized and their distinctive cytotoxicty was disclosed. 12n our preceding papers dealt with oligostilenes in the stem bark of Vatica rassak, the structures of a stilbene trimer (vaticanol A), 8 two tetramers (vaticanols B and C) 8 and a hexamer (vaticanol D), 9 were described.They are commonly composed of a 3,5,4'-trihydroxystilbene (resveratrol).Further investigation of the acetone extract resulted in isolation of two new oligostilbenoids, vaticanols E (1) and F (2), together with three new O-glucosyl oligostilbenoids, vaticasides A-C (3-5).This paper deals with their structure elucidation including the relative configuration.Vaticanol E (1), a pale yellow amorphous powder, showed a positive reaction to the Gibbs test.The absorption band in the UV spectra showed the presence of aromatic rings (284 nm).The [M-H] -ion peak at m/z 679.1971 in the high-resolution (HR) FABMS corresponds to the molecular formula of C 42 H 32 O 9 .The 1 H NMR spectrum (Table ) showed the presence of three 4-hydroxyphenyl groups [δ 7.77,
Sculpting the multicarrier spectrum: a novel projection precoder (2009)

A novel spectrum-sculpting precoder flexibly suppresses emitted power in predefined parts of the spectrum by tens of decibels. The precoder is particularly suitable in cognitive OFDM systems where the emitted signal's spectrum is adapted to time-varying reigning radio circumstances.
An Ontology-based method and tool for cross-domain requirements visualization (2011)

The complexity associated with understanding the cross-domain scope of a requirement has always been a challenge. Requirement Analysts use their experience in determining the functional scope boundaries of requirements. However, chances of missing out key concepts in domains peripheral to the domain of interest are quite high. Ontologies are increasingly becoming the standard way of representing shared understanding of a domain and their use in understanding and visualizing the cross-domain scope of requirements can be a step towards improving the completeness of requirements. We present a method - based on ontology mapping technique, and an assisting tool that would help Requirement Analysts visualize - how requirements span across multiple domains.
Tailoring the Electrical Properties of Inverse Silicon Opals ‐ A Step Towards Optically Amplified Silicon Solar Cells (2008)

Inverse crystalline silicon opals (i-cSi-os) in the solid state and hydrogen-plasma passivated are studied, and charge-transport measurements reveal for the first time that their electrical properties are acceptable for device applications. The omnidirectional photonic band gap of i-cSi-os can be uniquely integrated with the semiconductivity of silicon, enhancing their photon-to-electron conversion efficiency.

System of phase oscillators with diagonalizable interaction (2003)

We consider a system of N phase oscillators having randomly distributed natural frequencies and diagonalizable interactions among the oscillators. We show that in the limit of N going to infinity, all solutions of such a system are incoherent with probability one for any strength of coupling, which implies that there is no sharp transition from incoherence to coherence as the coupling strength is increased, in striking contrast to Kuramoto's (special) oscillator system.
Delay-Doppler-Based Key Generation Using OTFS (2023)

Key generation for secure communication is challenging in high-mobility scenarios due to the low coherence time. This is further exacerbated in frequency-division duplex systems due to the non-reciprocal wireless channel in uplink and downlink. The current work leverages the symplectic Fourier transform to convert fast-varying time-frequency domain signals to slow-varying delay-Doppler (DD) domain and utilizes the wireless channel representation in the DD domain to generate shared keys. The proposed approach is evaluated in terms of key generation and mismatch rates considering correlated eavesdropper, as well as the various randomness criteria provided by the National Institute of Standards and Technology.

ELECTRICAL CHARACTERIZATION OF THIN-FILM ELECTROLUMINESCENT DEVICES (1997)

▪ Abstract Electrical characterization methods for the analysis of alternating current thin-film electroluminescent (ACTFEL) devices are reviewed. Particular emphasis is devoted to electrical characterization techniques because ACTFEL devices are electro-optic display devices whose performance is to a large extent determined by their electrical properties. A systematic procedure for ACTFEL electrical assessment is described. The utility of transient charge, voltage, current, and phosphor field analysis is explained. Steady-state electrical characterization methods discussed in this review include charge-voltage (Q-V), capacitance-voltage (C-V), internal charge-phosphor field (Q-F p ), and maximum charge-maximum applied voltage (Q max -V max ) analysis. These electrical characterization methods are illustrated by reviewing relevant results obtained from the analysis of evaporated ZnS:Mn and atomic layer epitaxy (ALE) SrS:Ce ACTFEL devices.
Dielectric Function of GaAs: a View Into Electron and Lattice Dynamics (1996)

Intense ultrafast optical excitation creates unique non-equilibrium conditions in a semiconductor, strongly modifies the bandstructure, and drives structural changes.1-3 Our previous results have shown that measuring fundamental optical properties, such as the dielectric constant1 and second-order susceptibility2 is a tremendous improvement over ordinary reflectivity and second-harmonic measurements, and yields results qualitatively different from previous assumptions. We now move beyond single-frequency measurements using a new broadband spectroscopic technique to simultaneously monitor the response of the dielectric function e(ω) of GaAs across the spectral range from 1.5 to 3.5 eV, with 100-fs temporal resolution.
Proprioceptive State Estimation of Legged Robots with Kinematic Chain Modeling (2022)

Legged robot locomotion is a challenging task due to a myriad of sub-problems, such as the hybrid dynamics of foot contact and the effects of the desired gait on the terrain. Accurate and efficient state estimation of the floating base and the feet joints can help alleviate much of these issues by providing feedback information to robot controllers. Current state estimation methods are highly reliant on a conjunction of visual and inertial measurements to provide real-time estimates, thus being handicapped in perceptually poor environments. In this work, we show that by leveraging the kinematic chain model of the robot via a factor graph formulation, we can perform state estimation of the base and the leg joints using primarily proprioceptive inertial data. We perform state estimation using a combination of preintegrated IMU measurements, forward kinematic computations, and contact detections in a factor-graph based framework, allowing our state estimate to be constrained by the robot model. Experimental results in simulation and on hardware show that our approach out-performs current proprioceptive state estimation methods by 27% on average, while being generalizable to a variety of legged robot platforms. We demonstrate our results both quantitatively and qualitatively on a wide variety of trajectories.
Reliable characterization of materials and nanostructured systems <<50nm using coherent EUV beams (2016)

Coherent extreme ultraviolet beams from tabletop high harmonic generation offer revolutionary capabilities for observing nanoscale systems on their intrinsic length and time scales. By launching and monitoring acoustic waves in such systems, we fully characterize sub-10nm films and find that the Poisson’s ratio of low-k dielectric materials does not stay constant as often assumed, but increases when bond coordination is bellow a critical value. Within the same measurement, by following the heat dissipation dynamics from nano-gratings of width 20-1000nm and different periodicities, we confirm the effects of the newly identified collectively-diffusive regime, where close-spaced nanowires cool faster than widely-spaced ones.
Line-harmonics reduction techniques for consumer electronics and low-power electronic equipment (2002)

This paper discusses line-harmonics reduction techniques for consumer electronics and the other low-power electronic equipment of less than several hundred watts. Among some single-phase and single-stage PFC converters, a parallel-structure converter, where only a single switch is used to reduce both the line harmonics and the output-voltage ripple, is described in detail. The experimental results have confirmed that this converter meets the IEC regulation of line harmonic distortion, and that it obtains the suppression of output-voltage ripple and a high efficiency.
A Recursive Least-squares Algorithm Based on the Nearest Kronecker Product Decomposition (2019)

The recursive least-squares (RLS) adaptive filter is an appealing choice in system identification problems, mainly due to its fast convergence rate. However, this algorithm is computationally very complex, which may make it useless for the identification of high length impulse responses, like in echo cancellation. In this paper, we focus on a new approach to improve the efficiency of the RLS algorithm. The basic idea is to exploit the impulse response decomposition based on the nearest Kronecker product and low-rank approximation. Thus, a high-dimension system identification problem is reformulated in terms of low-dimension problems, which are tensorized together. Simulations performed in the context of echo cancellation indicate the good performance of the RLS algorithm based on this approach.
Threshold Level Photoablation Of Metals: Ejected Ion Energy Distributions (1989)

Laser sources can create plasmas at metallic surfaces when radiation fluxes are above 106 W/cm2. These plasmas grow rapidly, absorbing the incident laser radiation and strongly influencing the laser coupling to the surface.

Portable surgery master station for mobile robotic telesurgery (2007)

We describe a system that provides a low-cost, portable control station for experimentation in mobile robotic telesurgery. The software and hardware implementation of our system are described in detail. The device mapping between the Haptic Interface Devices (HID) and the surgical robot that enable the surgeon to effectively teleoperate the surgical robot are explained along with our communication protocols for telesurgery. We have also provided our initial results from extensive field testing of our system in different hardware and software configurations and challenging locations. We focus on working under sub-optimal network conditions for field operation in remote environments, and the importance of interoperability and distribution among networked surgical technologies.
Alisiaquinones and Alisiaquinol, Dual Inhibitors of Plasmodium falciparum Enzyme Targets from a New Caledonian Deep Water Sponge (2008)

Four new meroterpenes, alisiaquinones A-C (1-3) and alisiaquinol (4), were isolated from a New Caledonian deep water sponge. Their structures and relative stereochemistry were elucidated by spectroscopic data analysis. They are related to xestoquinone, but showed unusual substitution on a tetrahydrofuran junction. They displayed micromolar range activity on two enzymatic targets of importance for the control of malaria, the plasmodial kinase Pfnek-1 and a protein farnesyl transferase, as well as on different chloroquine-sensitive and -resistant strains of Plasmodium falciparum. Alisiaquinone C displayed a submicromolar activity on P. falciparum and a competitive selectivity index on the different plasmodial strains.

Enhancing ascorbate in fruits and tubers through over‐expression of the l‐galactose pathway gene GDP‐l‐galactose phosphorylase (2011)

Ascorbate, or vitamin C, is obtained by humans mostly from plant sources. Various approaches have been made to increase ascorbate in plants by transgenic means. Most of these attempts have involved leaf material from model plants, with little success reported using genes from the generally accepted l-galactose pathway of ascorbate biosynthesis. We focused on increasing ascorbate in commercially significant edible plant organs using a gene, GDP-l-galactose phosphorylase (GGP or VTC2), that we had previously shown to increase ascorbate concentration in tobacco and Arabidopsis thaliana. The coding sequence of Actinidia chinensis GGP, under the control of the 35S promoter, was expressed in tomato and strawberry. Potato was transformed with potato or Arabidopsis GGP genes under the control of the 35S promoter or a polyubiquitin promoter (potato only). Five lines of tomato, up to nine lines of potato, and eight lines of strawberry were regenerated for each construct. Three lines of tomato had a threefold to sixfold increase in fruit ascorbate, and all lines of strawberry showed a twofold increase. All but one line of each potato construct also showed an increase in tuber ascorbate of up to threefold. Interestingly, in tomato fruit, increased ascorbate was associated with loss of seed and the jelly of locular tissue surrounding the seed which was not seen in strawberry. In both strawberry and tomato, an increase in polyphenolic content was associated with increased ascorbate. These results show that GGP can be used to raise significantly ascorbate concentration in commercially significant edible crops.
High reflectivity dielectric mirror deposition by reactive magnetron sputtering (1992)

We use room temperature reactive sputter deposition from a silicon target to deposit Si, Si3N4, and SiO2 layers. The resulting amorphous layers are grown to form highly reflecting dielectric mirrors and used for coating end facets of layers. Among the advantages of our computer controlled sputter deposition process are the reproducibly excellent optical quality, good adhesion properties together with high chemical and thermal stability of the deposited films. We use Si/SiO2 mirrors for broadband infrared distributed Bragg reflectors and Si3N4/SiO2 multilayers in the visible wavelength range. The high (≳99%) reflectivities which are obtained from these mirrors make them suitable for use in vertical-cavity surface emitting and low-threshold edge-emitting lasers.
Inversion Layer Mobility in High-k Dielectric MOSFETs - Intrinsic Mobility Degradation by Electric Dipoles at High-k/SiO2 Interface (2008)

An intrinsic mobility degradation mechanism in high-k gate stacks is proposed. Scattering, due to the electric dipole potential formed at the high-k/SiO2 interface, strongly affects the electron mobility in a metal/high-k gate stack. Comparison of the mobilities in HfO2 gate stacks with different optical phonon structures also revealed that the contribution of remote phonon scattering to mobility degradation is rather small.
The requirements for activation of an antigen specific T-cell clone via the CD3 complex. (1992)

We have studied the requirements for the activation of the haemagglutinin peptide specific cloned T-cell HA1.7 by anti-CD3 antibodies and the mechanism of modulation of the CD3 complex. Cross-linking of the complex either by a soluble antibody second layer or an immobilized matrix of antibody is necessary for induction of a proliferative response. This proliferative response is totally dependent on exogenously added IL-2. Modulation of the cross-linked CD3 complex is by patching, capping and internalization of the antigen and is not essential for the proliferative response.
Deciphering Teneurin Domains That Facilitate Cellular Recognition, Cell–Cell Adhesion, and Neurite Outgrowth Using Atomic Force Microscopy-Based Single-Cell Force Spectroscopy (2013)

Teneurins are evolutionarily conserved transmembrane receptors that function as axon guidance and target selection molecules in the developing nervous system. How teneurins recognize each other, whether they establish neuronal adhesion, and which teneurin specific interactions guide neurons remains to be determined. To reveal insight into these pertinent questions we combine atomic force microscopy-based single-cell force spectroscopy with genetic engineering and quantify the interactions teneurins establish between animal cells. Using a combinatorial approach of deletions and swaps of teneurin-1 and teneurin-2 domains, we unravel that teneurins use their NHL (NCL-1, HT2A, and Lin-41) domain to select homophilic teneurins from adjacent cells. This homophilic recognition of teneurins initiates cell-cell adhesion that, dependent on the intracellular domain, strengthens over time. Neurite outgrowth assays show that establishing and strengthening of teneurin-mediated homophilic cell-cell adhesion is required to stop outgrowth. On the basis of the results, we introduce a molecular model of teneurin domains that specify cellular recognition, adhesion strengthening, and neuronal pathfinding. The combined force spectroscopy and genetic approach can be applied to quantitatively decipher the contribution of any neuronal receptor domain and more generally of a given cell surface receptor domain to cell-cell recognition and adhesion.
SmartObjects (2015)

The increasing number of smart objects in our everyday life shapes how we interact beyond the desktop.
