Performance Comparisons of Wireless Mesh IP Video Surveillance Models (2015)

This paper investigates the wireless mesh IP video surveillance models and evaluates their performance in terms of throughput, End-to-End delay and jitter. Wireless Mesh Network consists of either a wireless or wired backbone network from which Mesh Gateways (MGs), Access Points (APs), wireless Mesh Routers (MRs) and Mesh Client (MCs) are linked together through carefully designed topologies. WMN networks have the advantage of high reliability, scalability and low capital outlay. The H.264/AVC standard is a joint standard for video compression promoted by the International Telecommunication Union Telecom Sector and the ISO/IEC. The H.264/AVC standard specifies four video formats: Common Intermediate Format (CIF), Quarter CIF (QCIF), Sub Quarter CIF (SQCIF) and 4CIF. Results in this work show that flow throughput is half the network throughput when the hop count for a given topology is two. Additionally, at fixed number of nodes, the Tree Mesh topology outperformed the Fork Mesh and Cross Mesh topology by a factor of 2.8 and 7 in End-to-end and jitter terms respectively.
"Quantum Supremacy" and the Complexity of Random Circuit Sampling (2018)

A critical milestone on the path to useful quantum computers is quantum supremacy - a demonstration of a quantum computation that is prohibitively hard for classical computers. A leading near-term candidate, put forth by the Google/UCSB team, is sampling from the probability distributions of randomly chosen quantum circuits, which we call Random Circuit Sampling (RCS). In this paper we study both the hardness and verification of RCS. While RCS was defined with experimental realization in mind, we show complexity theoretic evidence of hardness that is on par with the strongest theoretical proposals for supremacy. Specifically, we show that RCS satisfies an average-case hardness condition - computing output probabilities of typical quantum circuits is as hard as computing them in the worst-case, and therefore #P-hard. Our reduction exploits the polynomial structure in the output amplitudes of random quantum circuits, enabled by the Feynman path integral. In addition, it follows from known results that RCS satisfies an anti-concentration property, making it the first supremacy proposal with both average-case hardness and anti-concentration.

The growth of high-quality epitaxial ${\mathrm{CaSi}}_{2}$ films on Si(111) is described along with a determination of the silicide atomic structure and the structure of the ${\mathrm{CaSi}}_{2}$/Si interface. These films constitute the first example of an epitaxial non-transition-metal silicide. The lack of d electrons and the large difference in electronegativity between Ca and Si promise to endow epitaxial calcium silicide and the silicide-silicon interface with intriguingly different electronic properties from the thoroughly studied transition-metal silicides.

Applying hand gesture recognition and joint tracking to a TV controller using CNN and Convolutional Pose Machine (2018)

This paper introduces a novel TV control simulation system that recognizes hand gestures and track hand joints based on Convolutional Neural Networks (CNN) and Convolutional Pose Machines (CPM). The system provides users with an intuitive means of controlling television functions through hand gestures. Moreover, based on relative position and angle of fingers, users can manipulate an onscreen cursor and continuously modify volume & channels at varying speed. We achieved 95.8 percent testing accuracy in 19 gestures with 4 subjects, and average 11 & 45 fps while conducting CPM and CNN respectively.
Electron trapping in oxide grown from polycrystalline silicon (1979)

This paper presents a method of characterizing the N-σ (density -- "capture-cross-section") distribution of electron traps in insulators. Requiring only voltage-time measurements made at constant currents, this method has found for oxides grown from poly-Si N ∝ σ <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1.16</sup> . The previously reported absence of saturation in electron trapping in these oxides is explained by the high density of traps with small cross-sections. The trap density and cross-section are insensitive to the oxidation condition. The observed trapping characteristics is consistent with this density-cross-section distribution, first order rate dynamics of trapping, and unnoticeable new trap generation by field or current stressing under the test conditions.
Histamine H<sub>3</sub> receptor‐mediated impairment of contextual fear conditioning and <i>in‐vivo</i> inhibition of cholinergic transmission in the rat basolateral amygdala (2001)

We investigated the effects of agents acting at histamine receptors on both, spontaneous release of ACh from the basolateral amygdala (BLA) of freely moving rats, and fear conditioning. Extensive evidence suggests that the effects of histamine on cognition might be explained by the modulation of cholinergic systems. Using the microdialysis technique in freely moving rats, we demonstrated that perfusion of the BLA with histaminergic compounds modulates the spontaneous release of ACh. The addition of 100 mm KCl to the perfusion medium strongly stimulated ACh release, whereas, 0.5 microm tetrodotoxin (TTX) inhibited spontaneous ACh release by more than 50%. Histaminergic H3 antagonists (ciproxifan, clobenpropit and thioperamide), directly administered to the BLA, decreased ACh spontaneous release, an effect fully antagonized by the simultaneous perfusion of the BLA with cimetidine, an H2 antagonist. Local administration of cimetidine alone increased ACh spontaneous release slightly, but significantly. Conversely, the administration of H1 antagonists failed to alter ACh spontaneous release. Rats receiving intra-BLA, bilateral injections of the H3 antagonists at doses similar to those inhibiting ACh spontaneous release, immediately after contextual fear conditioning, showed memory consolidation impairment of contextual fear conditioning. Post-training, bilateral injections of 50 microg scopolamine also had an adverse effect on memory retention. These observations provide the first evidence that histamine receptors are involved in the modulation of cholinergic tone in the amygdala and in the consolidation of fear conditioning.

Static Backward Demand-Driven Slicing (2014)

Program slicing identifies the program parts that may affect certain properties of the program, such as the outcomes of conditions affecting the program flow. Ottenstein's Program Dependence Graph (PDG) based algorithm is the state-of-practice for static slicing today: it is well-suited in applications where many slices are computed, since the cost of building the PDG then can be amortized over the slices. But there are applications that require few slices of a given program, and where computing all the dependencies may be unnecessary. We present a light-weight interprocedural algorithm for backward static slicing where the data dependence analysis is done using a variant of the Strongly Live Variables (SLV) analysis. This allows us to avoid building the Data Dependence Graph, and to slice program statements "on-the-fly'' during the SLV analysis which is potentially faster for computing few slices. Furthermore we use an abstract interpretation-based value analysis to extend our slicing algorithm to slice low-level code, where data dependencies are not evident due to dynamically calculated addresses. Our algorithm computes slices as sets of Control Flow Graph nodes: we show how to adapt existing techniques to generate executable slices that correspond to semantically correct code, where jump statements have been inserted at appropriate places. We have implemented our slicing algorithms, and made an experimental evaluation comparing them with the standard PDG-based algorithm for a number of example programs. We obtain the same accuracy as for PDG-based slicing, sometimes with substantial improvements in performance.
The Magnetoelectric Dipole—A Wideband Antenna for Base Stations in Mobile Communications (2012)

In this paper, stringent requirements imposed on the design of base station antennas for mobile communications are summarized. Conventional techniques for implementing base station antennas are reviewed. The complementary antenna concept of combining an electric dipole with a magnetic dipole is reconsidered. Recently, this kind of antenna has been commonly called a “Huygen's source.” The purpose is to develop wideband unidirectional antennas with stable frequency characteristics and low back radiation. Based on this concept, the magnetoelectric dipole was invented by integrating an electric dipole with an -probe fed shorted quarter-wave patch antenna. A number of magnetoelectric dipoles with different radiation patterns and different polarizations have been developed in recent years. An overview of the characteristics of this new class of complementary antennas is presented. Major design challenges are explained. Finally, a new magnetoelectric dipole that is low in profile and robust in structure is presented. The magnetic dipole part of this antenna is realized by a triangular-shaped loop antenna. The antenna is inherently direct current (dc) grounded, which satisfies the requirement for outdoor applications.
Quantification of quaternary mixtures of alcohols: a comparison of reflectometric interference spectroscopy and surface plasmon resonance spectroscopy (2004)

In this paper the quantification of quaternary mixtures of the homologous series of the alcohols methanol to n-butanol in the gaseous phase is presented. Time-resolved reflectometric interference spectroscopy (RIfS) and surface plasmon resonance spectroscopy (SPR) are used. An array consisting of two layers of a size-selective microporous polymer (Makrolon®) plus the polar polymer polyetherurethan (PUT) is used for RIfS measurements. The time-dependent kinetics of sorption and desorption of the analytes is evaluated by the use of neural networks. As the time-dependent sensor signals differ significantly for each analyte, quantifications with only a single microporous layer are possible. Thus, measurements using a thinner microporous layer for the SPR set-up are also performed, showing faster sorption and desorption. Therefore, measurements can be performed much faster by using the SPR set-up.
Adaptive beamforming using the multistage Wiener filter with a soft stop (2001)

To use adaptive beamforming in underwater acoustics, this paper considers processing data in short rank-deficient blocks so the moving interferers will not move as far per block. As a baseline algorithm, we consider the traditional minimum variance distortionless response (MVDR) formula using a data sample covariance matrix inversion (SMI) with diagonal loading added to limit the downward bias and signal cancellation associated with rank deficiency. As a new algorithm, we use the multistage Wiener filter (MWF) terminated with a "soft stop" to limit the downward bias and signal cancellation. The soft stop approach also applies to other adaptive filtering problems where the target signals are present in the training data.
<title>Three-dimensional profile measurement by using an artificial neural network</title> (1998)

This paper introduces 3D profiles noncontact measurement method by using a kind of artificial neural network- backpropagation network. It makes a detail discussion on optical system, data acquisition, and how to train the BP network. An object is projected by a laser stripe light, and the lien image of the object is captured by a CCD camera. The input data of BP network is given from a series of image on CCD by certain image processing technology. Once a mapping relationship of coordinates between CCD camera image plane and related position in object's space is set up by sing BP network, the image plane coordinates of any objects are used as the input data of BP network it will immediately obtain the corresponding coordinates in space according to the output. Thus the profile can be easily established by these coordinates. This method reduces the requirement for system accuracy, and no need to test and a light the whole system in advance accurately.
Inter-domain networking innovation on steroids: empowering ixps with SDN capabilities (2016)

While innovation in inter-domain routing has remained stagnant for over a decade, Internet exchange points (IXPs) are consolidating their role as economically advantageous interconnection points for reducing path latencies and exchanging ever increasing amounts of traffic. As such, IXPs appear as a natural place to foster network innovation and assess the benefits of SDN, a recent technological trend that has already boosted innovation within data center networks. In this article, we give a comprehensive overview of use cases for SDN at IXPs, which leverage the superior vantage point of an IXP to introduce advanced features like load balancing and DDoS mitigation. We discuss the benefits of SDN solutions by analyzing real-world data from one of the largest IXPs. We also leverage insights into IXP operations to shape benefits not only for members but also for operators.
Compressive Volume Rendering (2015)

Abstract Compressive rendering refers to the process of reconstructing a full image from a small subset of the rendered pixels, thereby expediting the rendering task. In this paper, we empirically investigate three image order techniques for compressive rendering that are suitable for direct volume rendering. The first technique is based on the theory of compressed sensing and leverages the sparsity of the image gradient in the Fourier domain. The latter techniques exploit smoothness properties of the rendered image; the second technique recovers the missing pixels via a total variation minimization procedure while the third technique incorporates a smoothness prior in a variational reconstruction framework employing interpolating cubic B‐splines. We compare and contrast the three techniques in terms of quality, efficiency and sensitivity to the distribution of pixels. Our results show that smoothness‐based techniques significantly outperform techniques that are based on compressed sensing and are also robust in the presence of highly incomplete information. We achieve high quality recovery with as little as 20% of the pixels distributed uniformly in screen space.
Single-Trial Regression Elucidates the Role of Prefrontal Theta Oscillations in Response Conflict (2011)

In most cognitive neuroscience experiments there are many behavioral and experimental dynamics, and many indices of brain activity, that vary from trial to trial. For example, in studies of response conflict, conflict is usually treated as a binary variable (i.e., response conflict exists or does not in any given trial), whereas some evidence and intuition suggests that conflict may vary in intensity from trial to trial. Here we demonstrate that single-trial multiple regression of time-frequency electrophysiological activity reveals neural mechanisms of cognitive control that are not apparent in cross-trial averages. We also introduce a novel extension to oscillation phase coherence and synchronization analyses, based on "weighted" phase modulation, that has advantages over standard coherence measures in terms of linking electrophysiological dynamics to trial-varying behavior and experimental variables. After replicating previous response conflict findings using trial-averaged data, we extend these findings using single-trial analytic methods to provide novel evidence for the role of medial frontal-lateral prefrontal theta-band synchronization in conflict-induced response time dynamics, including a role for lateral prefrontal theta-band activity in biasing response times according to perceptual conflict. Given that these methods shed new light on the prefrontal mechanisms of response conflict, they are also likely to be useful for investigating other neurocognitive processes.
Self-starting 65-fs pulses from a Ti:sapphire laser (1997)

We demonstrate self-starting 6.5-fs pulses from a Kerr-lens mode-locked Ti:sapphire laser with 200-mW average output power at a pulse repetition rate of ~86 M Hz. This is to our knowledge the shortest pulse ever generated directly from a laser. For dispersion compensation we used a prism pair in combination with double-chirped mirrors, which balances the higher-order dispersion of the prism pair and therefore flattens the average total group-delay dispersion in the laser cavity. For self-starting mode locking we used a broadband semiconductor saturable-absorber mirror.
Fast and Effective Subgroup Mining for Continuous Target Variables. (2009)

Subgroup mining is a flexible data mining method that considers a given target variable and aims to discover interesting subgroups with re-spect to this property of interest. In this paper, we especially focus on the handling of continuous target variables: We propose novel formaliza-tions of effective pruning strategies for reducing the search space, and we present the SD-Map* algorithm that enables fast subgroup mining for continuous target variables. Furthermore, we present effective visualization techniques that are seamlessly integrated in the semi-automatic sub-group mining process. The evaluation demon-strates the efficiency and effectiveness of the pre-sented approaches. 1
HUMAN CLASS II ANTIGENS (1986)

Several monoclonal antibodies (McAbs) to human class II antigens are described; three of these recognize monomorphic epitopes, and two are polymorphic. The biochemical nature of the reactive epitopes was investigated by determining the binding ability of the McAbs to protease- or glycosidase-treated antigen preparations. Both of the polymorphic McAbs recognized protein-defined epitopes. However, for one of the antibodies F5C9, carbohydrate residues were also implicated. The extent of carbohydrate involvement varied with class II antigens of different DR specificity, suggesting that the proximity of the F5C9 epitope to carbohydrate side chains can vary. One of the three monomorphic McAbs recognized a protein-defined epitope, while the other two antibodies detected epitopes in which carbohydrates were involved. These results indicate that both protein and carbohydrate residues of the human class II antigens can influence the epitopes recognized by murine McAbs. This could explain some of the apparent complexities of the anti-human class II McAbs.
Phorbol esters stimulate macropinocytosis and solute flow through macrophages (1989)

The morphology and kinetics of pinocytosis by bone marrow-derived macrophages were studied to determine how stimulation by phorbol esters increases net solute accumulation. Application of phorbol myristate acetate (PMA) increased both the abundance of macropinosomes and the rate of solute flow through the endocytic compartment. The large pinosomes originated as ruffles at the cell margins that folded back on themselves, internalizing extracellular medium and solutes. I examined how stimulation affects the kinetics of pinocytic influx, accumulation, and subsequent efflux of the fluorescent dye Lucifer Yellow (LY) in macrophages. Both the accumulation of LY and its subsequent efflux were temperature-dependent and directly proportional to the concentration of LY in the extracellular medium. Macrophages incubated in PMA and LY for 2 h accumulated four to six times more LY than did macrophages in LY alone. If after pinocytosis the macrophages were washed and reincubated in unlabeled medium for a 1 h chase period, some of the internalized LY was regurgitated from the cells. Inclusion of PMA in the chase medium increased efflux of LY. In contrast, a smaller percentage of LY was regurgitated from macrophages which were both loaded and chased in the presence of PMA. This indicates that although efflux is increased by PMA, influx increases more, and therefore more of the LY entering by pinocytosis is retained within the cell. I suggest that macropinocytosis increases the size difference between pinosomes and efflux vesicles, and that that difference increases greatly both solute accumulation and membrane flow through the endocytic compartment.
