Design for Reliability: The RF Power LDMOSFET

The design of lateral diffused MOSFETs operating under continuous peak power in RF communication applications is one of the most demanding among semiconductor applications. This paper discusses design parameters related to the optimum performance of the transistor and constraints introduced by the fabrication process in achieving them. Nonstandard processing steps include thick pad oxides, a sinker to connect source to the bottom substrate, metal silicided gates, a source shield over the drift region, and often gold metallization for improved electromigration. Additionally, the device requires careful optimization for control of hot-carrier-related bias drift. The impact of negative charge injection in the gate oxide is to degrade the power gain and at higher output power levels, the linearity. The difficulties in assessment of the true impact of hot carriers on these parameters via measurement are highlighted. The contribution of matching impedances and class of bias on hot-carrier degradation is extracted via modeling. A ldquodesign for reliabilityrdquo approach for this product is investigated with four designs of the drift region, evaluated in terms of transconductance, on-resistance, breakdown voltage, capacitance, and hot-carrier immunity. A second-generation source shield demonstrates a tradeoff via significant reduction of feedback capacitance at a cost to transconductance. A deep drift design shows optimization in terms of gain without compromise to the hot-carrier immunity. Recent advances made in terms of packaging and electromigration are reviewed.
Annotation and Classification of French Feedback Communicative Functions

Feedback utterances are among the most fre- quent in dialogue. Feedback is also a crucial aspect of all linguistic theories that take social interaction involving language into account. However, determining communicative func- tions is a notoriously difficult task both for human interpreters and systems. It involves an interpretative process that integrates vari- ous sources of information. Existing work on communicative function classification comes from either dialogue act tagging where it is generally coarse grained concerning the feed- back phenomena or it is token-based and does not address the variety of forms that feed- back utterances can take. This paper intro- duces an annotation framework, the dataset and the related annotation campaign (involv- ing 7 raters to annotate nearly 6000 utter- ances). We present its evaluation not merely in terms of inter-rater agreement but also in terms of usability of the resulting reference dataset both from a linguistic research per- spective and from a more applicative view- point.
Scan registration with multi-scale k-means normal distributions transform

The normal distributions transform (NDT) scan registration algorithm has been shown to produce good results, however, has a tendency to converge to a local minimum if the initial parameter error is large. In order to improve the convergence basin for NDT, a multi-scale k-means NDT (MSKM-NDT) variant is proposed. This approach divides the point cloud using k-means clustering and performs the optimization step at multiple scales of cluster sizes. The k-means clustering approach guarantees that the optimization will converge, as it resolves the issue of discontinuities in the cost function found in the standard NDT algorithm. The optimization step of the NDT algorithm is performed over a decreasing scale, which greatly improves the basin of convergence. Experiments show that this approach can be used to register partially overlapping scans with large initial transformation error.
Study of the Advance Payment Financing Model Based on E-Commerce Platform

Electronic information network technology is growing faster with the rapid development of information technology, the advance payment financing model based on e-commerce platform becoming mature step by step. We proceeded a discussion about the mechanism of the advance payment financing model based on e-commerce platform. Then we analysed the principal parts which participate in this financing procedure, and made the traditional advance payment compared with this new financing model. At last we concluded that advance payment financing model based on e-commerce platform can not only reduce the risk of relevant parties, but also can increase the financing efficiency.
Automatic Phonetization-based Statistical Linguistic Study of Standard Arabic

Statistical studies based on automatic phonetic transcription of Standard Arabic texts are rare, and even though studies have been performed, they have been done only on one level – phoneme or syllable – and the results cannot be generalized on the language as a whole. In this paper we automatically derived accurate statistical information about phonemes, allophones, syllables, and allosyllables in Standard Arabic. A corpus of more than 5 million words, including words and sentences from both Classical Arabic and Modern Standard Arabic, has been prepared and preprocessed. We developed a software package to accomplish a rule-based automatic transcription from written Standard Arabic text to the corresponding linguistic units at four levels: phoneme, allophone, syllable, and allosyllable. After testing the software on four corpora including more than 57000 vocabulary words, and achieving a very high accuracy (> 99 %) on the four levels, we used this software as a reliable tool for the automatic transcription of the corpus used in this paper and evaluated the following: 1) the vocabulary phonemes, allophones, syllables, and allosyllables with their specific percentages in Standard Arabic. 2) the best curve equation from the distribution of phonemes, allophones, syllables, and allosyllables normalized frequencies. 3) important statistical information, such as percentage of consonants and vowels, percentage of the consonants classified by the place and way of articulation, the transition probability matrix between phonemes, and percentages of syllables according to the type of syllable, etc. Fadi Sindran, Firas Mualla, Tino Haderlein, Khaled Daqrouq & Elmar Nöth International Journal of Computational Linguistics (IJCL), Volume (7) : Issue (2) : 2016 39
Ieee Transactions on Wireless Communications, Accepted for Publication Asymmetric Cooperative Communications Based Spectrum Leasing via Auctions in Cognitive Radio Networks

—Dynamic spectrum leasing (DSL) was proposed recently as a new paradigm for dynamic spectrum sharing (DSS) in cognitive radio networks (CRN's). In this paper, we propose a new way to encourage primary users to lease their spectrum: The secondary users (SU's) place bids indicating how much power they are willing to spend for relaying the primary signals to their destinations. In this formulation, the primary users achieve power savings due to asymmetric cooperation. We propose and analyze both a centralized and a distributed decision-making architecture for the secondary CRN. In the centralized architecture , a Secondary System Decision Center (SSDC) selects a bid for each primary channel based on optimal channel assignment for SU's. In the decentralized cognitive network architecture, we formulate an auction game-based protocol in which each SU independently places bids for each primary channel and receivers of each primary link pick the bid that will lead to the most power savings. A simple and robust distributed reinforcement learning mechanism is developed to allow the users to revise their bids and to increase their rewards. The performance results show the significant impact of reinforcement learning in both improving spectrum utilization and meeting individual SU performance requirements.
Induction of Cross-Tolerance by Lipopolysaccharide and Highly Purified Lipoteichoic Acid Via Different Toll-Like Receptors Independent of Paracrine Mediators1

Exposure of macrophages to LPS induces a state of hyporesponsiveness to subsequent stimulation with LPS termed LPS desensitization or tolerance. To date, it is not known whether similar mechanisms of macrophage refractoriness are induced on contact with components of Gram-positive bacteria. In the present study, we demonstrate that pretreatment with highly purified lipoteichoic acid (LTA) results in suppression of cytokine release on restimulation with LTA in vitro and in vivo in both C3H/HeN and C3H/HeJ mice, but not in macrophages from Toll-like receptor (TLR)-2-deficient mice. Furthermore, desensitization in response to LPS or LTA exposure also inhibits responses to the other stimulus (“cross-tolerance”), suggesting that signaling pathways shared by TLR2 and TLR4 are impaired during tolerance. Finally, we show that LPS- or LTA-induced cross-tolerance is not transferred to hyporesponsive cells cocultured with LPS/LTA-responsive macrophages, showing that soluble mediators do not suffice for tolerance induction in neighboring cells.
Cloud storage hub: Data management for IoT and industry 4.0 applications: Towards a consistent enterprise information management system

Since computers are used in industry the idea of Enterprise Data Management (EDM) and Enterprise Information Systems (EIS) is a never-ending discussion. However, the concepts, techniques, and products are complex and companies failed to implement an Enterprise Information Management System that provides real-time and consistent data. This contribution presents an approach for data management in the new era of IoT, cloud, and Industry 4.0. This so-called Cloud Storage Hub (CSH) integrates different data sources, e.g. IoT devices, RDBMS, XML, cloud apps, through a mapping and rule system, so that a consolidated and consistent view on enterprise data is possible enabling management apps, e.g. for Analytics / BI, to access this data easily and convenient through a single API.
The identification of parasites in fish tissue sections

The identification of parasites in tissue sections is often difficult and fresh specimens are always required for accurate taxonomical classification. However, histological sections are in many cases the only material available and the identification of parasites in sections the subject of the recent histopathology workshop held in Dublin. The group reviewed the characteristics of representative protozoan and metazoan parasites in sections and identified key features to aid identification. A CD from the workshop will be compiled as a reference source.
Climate Change Impacts on Environmental and Human Exposure to Mercury in the Arctic

This paper reviews information from the literature and the EU ArcRisk project to assess whether climate change results in an increase or decrease in exposure to mercury (Hg) in the Arctic, and if this in turn will impact the risks related to its harmful effects. It presents the state-of-the art of knowledge on atmospheric mercury emissions from anthropogenic sources worldwide, the long-range transport to the Arctic, and it discusses the likely environmental fate and exposure effects on population groups in the Arctic under climate change conditions. The paper also includes information about the likely synergy effects (co-benefits) current and new climate change polices and mitigation options might have on mercury emissions reductions in the future. The review concludes that reductions of mercury emission from anthropogenic sources worldwide would need to be introduced as soon as possible in order to assure lowering the adverse impact of climate change on human health. Scientific information currently available, however, is not in the position to clearly answer whether climate change will increase or decrease the risk of exposure to mercury in the Arctic. New research should therefore be undertaken to model the relationships between climate change and mercury exposure.
Electrostatic and nonpolar peptide-membrane interactions. Lipid binding and functional properties of somatostatin analogues of charge z = +1 to z = +3.

The interaction of four structurally related somatostatin analogues (effective electric charge +0.4 < or = < or = +3) with lipid membranes was studied with titration calorimetry and was compared with the functional activity of the peptides. Surface activity measurements provided average cross-sections of 70 or 135 A2, indicating that the cyclic molecules orient at the air-water interface with their ring system either parallel (z = +3) or perpendicular (z = +1) to the surface or switching between the two orientations according to the surface density (z = +2). The nonspecific binding of the peptides to sonified lipid vesicles was enthalpy-driven with a delta H of -4 to -7.5 kcal/mol. A consistent quantitative analysis of the binding isotherms was achieved by combining electrostatic attractions, calculated via the Gouy-Chapman theory, with a nonspecific surface partition equilibrium for the nonpolar interactions. The electrostatic attraction of the cationic peptides varied strongly according to the peptide charge. Due to the flat ring structure of the cyclic peptides, their true physical charge was sensed at the membrane surface, and no "charge screening" was observed. Peptide binding to the negative charged membrane was accompanied by a proton-uptake of the N-terminal amino group of 0.23-0.38 H+/peptide. Deviations from the theoretical prediction of 0.39 H+/peptide can be explained by a preferential binding of the nonprotonated species. The nonpolar interactions, as described by the surface partition coefficients of the four peptides, fell into a narrow range of K congruent to 50-230 M-1 whereas the apparent overall binding constants were between 200 and 5000 M-1.

Maternal mRNAs are regulated by diverse P body–related mRNP granules during early Caenorhabditis elegans development

Processing bodies (P bodies) are conserved mRNA–protein (mRNP) granules that are thought to be cytoplasmic centers for mRNA repression and degradation. However, their specific functions in vivo remain poorly understood. We find that repressed maternal mRNAs and their regulators localize to P body–like mRNP granules in the Caenorhabditis elegans germ line. Surprisingly, several distinct types of regulated granules form during oocyte and embryo development. 3′ untranslated region elements direct mRNA targeting to one of these granule classes. The P body factor CAR-1/Rap55 promotes association of repressed mRNA with granules and contributes to repression of Notch/glp-1 mRNA. However, CAR-1 controls Notch/glp-1 only during late oogenesis, where it functions with the RNA-binding regulators PUF-5, PUF-6, and PUF-7. The P body protein CGH-1/Rck/Dhh1 differs from CAR-1 in control of granule morphology and promotes mRNP stability in arrested oocytes. Therefore, a system of diverse and regulated RNP granules elicits stage-specific functions that ensure proper mRNA control during early development.
Channel division multiple access for MTC under frequency-selective fading

In this paper, we study random access for machinetype communications (MTC) based on a multiple access scheme that exploits different channel state information (CSI) from active devices under frequency-selective fading, which is called channel division multiple access (ChDMA). In ChDMA, in order to use a low-complexity compressive sensing (CS) algorithm for multiuser detection (MUD) with a high transmission rate, we employ index modulation. Since the CSI is used as a signature for MUD, the CSI estimation becomes crucial, but suffers from the pilot collision. In order to lower the probability of pilot collisions, multiple transmissions of randomly selected pilots are considered.
Single-branch multi-tuned filter for power harmonic suppression

Single-tuned filter is a cost-effective device for harmonic mitigation, but the detuning derived from the variation of filter elements seriously decreases the filter's performance and it only can resonate at one harmonic frequency. This paper propose a single-branch multi-tuned filter (SBMTF) which consists of a single LC series branch but can simultaneously resonate at multiple harmonics and also can accommodate the variation of element parameters. The key element is an active reactor with two coupled windings, one called main winding is in series with the filter capacitor to form a tuned filter, and the other called compensation winding is used to continuously adjust the inductance of the main winding at different harmonic frequencies by injecting selective harmonic magnetic flux compensation current. With an automatic tuning controller, the SBMTF not only can mitigate multi-harmonics, but also can eliminate filter's detuning. A simulation model and an experimental prototype of the proposed single-branch multi-tuned filter have been implemented to investigate the static and dynamic characteristic of the filter. The results show that this SBMTF can well suppress multiple harmonics.
Locking and Stability of 3D Woven Composite Reinforcements

3D woven composite reinforcements preforming simulations are an unavoidable step of composite part processing. The present paper deals with thick composite fabric behavior modelling and issues arising during the numerical simulation of preforming. After the description of the independent deformation modes of initially orthotropic reinforcements, a physically motivated and invariant based hyperelastic strain energy density is introduced. This constitutive law is used to show the limitations of a classical finite element formulation in 3D fabric simulations. Tension locking is highlighted in bias extension tests and a reduced integration hexahedral finite element with specific physical hourglass stabilization is proposed. Instabilities due to the highly anisotropic behavior law, witnessed in bending dominated situations, are exposed and a stabilization procedure is initiated.
Design and simulation of an antenna-coupled TES bolometer

We present a new design of an antenna-coupled superconducting transition-edge sensor (TES) bolometer. The incident radiation is coupled to a membrane-based twin-slot antenna and then transmitted through lossless microstrip lines to lossy meander-like microstrip lines in which a NbSi film is located between strip and dielectric layer. The NbSi film serves as both power absorber and temperature sensor (thermometer). With the help of the electromagnetic simulation software High Frequency Structure Simulator (HFSS), we have studied the performance of the twin-slot antenna. The simulation results for radiation pattern and return loss show promising prospects for this TES bolometer design. The power absorption in NbSi film is another important aspect which will be modeled in the future.
The Granularity of Dust Particles when Sanding Wood and Wood-Based Materials

The article presents results of the granulometric composition of chip particles when sanding wood (beech) and wood-based materials (particleboard and semi-hardboard) using different types of sanders – wide belt sander, narrow belt sander, and hand sander. On the basis of the carried out sieve analyses, the proportion of produced particles, which can be marked as dust with the particle size of ≤ 80 μm, is high at the interval from 89.21% - 96.29 %. The highest percentage of dust particles was reached at dust from the hand disk sander. At the end of the article we point to possible technical safety measures – additional dust exhausting, suction, to possibly reduce the dust getting to the working environment.
Social anxiety disorder exhibit impaired networks involved in self and theory of mind processing

Abstract Most previous studies regarding social anxiety disorder (SAD) have focused on the role of emotional dysfunction, while impairments in self- and theory of mind (ToM)-processing have relatively been neglected. This study utilised functional connectivity density (FCD), resting-state functional connectivity (RSFC) and discriminant analyses to investigate impairments in self- and ToM-related networks in patients with SAD. Patients with SAD exhibited decreased long-range FCD in the right rostral anterior cingulate cortex (rACC) and decreased short-range FCD in the right superior temporal gyrus (STG)—key nodes involved in self- and ToM-processing, respectively. Decreased RSFC of the right rACC and STG with widespread frontal, temporal, posteromedial, sensorimotor, and somatosensory, regions was also observed in patients with SAD. Altered RSFC between the right rACC and bilateral superior frontal gyrus, between the right rACC and right middle frontal gyrus, and within the right STG itself provided the greatest contribution to individual diagnoses of SAD, with an accuracy of 84.5%. These results suggest that a lack of cognitive inhibition on emotional self-referential processing as well as impairments in social information integration may play critical roles in the pathomechanism of SAD and highlight the importance of recognising such features in the diagnosis and treatment of SAD.
Merit Aid, College Quality and College Completion: Massachusetts’ Adams Scholarship as an In-Kind Subsidy

We analyze a Massachusetts merit aid program in which high-scoring students received tuition waivers at in-state public colleges with lower graduation rates than available alternative colleges. A regression discontinuity design comparing students just above and below the eligibility threshold finds that students are remarkably willing to forgo college quality for relatively little money and that marginal students lowered their college completion rates by using the scholarship. These results imply that college quality has a substantial impact on college completion rates and that students likely do not understand this fact well. The theoretical prediction that in-kind subsidies of public institutions can reduce consumption of the subsidized good is shown to be empirically important.
A 3.0 Gb/s clock data recovery circuits based on digital DLL for clock-embedded display interface

A fast locking 3.0 Gb/s clock data recovery circuit (CDR) based on the digital DLL is proposed for intra-panel clock-embedded display interface. The CDR uses 3-level sub-ranging delay control in digital DLL. Overlapping range selection, successive approximation, and highly-linear timing amplifier are used for most, intermediate, and least significant bits of control, respectively to improve both jitter immunity and dynamic range of digital DLL. The designed chip occupies 0.076 mm2 active area in 0. 13μm CMOS technology and consumes 6.72 mW at 3.0 Gb/s from a 1.2 V supply. The rms and pk-to-pk jitters of the recovered clock are as small as 4.8 ps and 30.8 ps, respectively.
APERTURE SYNTHESIS OBSERVATIONS OF THE NEARBY SPIRAL NGC 6503: MODELING THE THIN AND THICK H i DISKS

We present sensitive aperture synthesis observations of the nearby, late-type spiral galaxy NGC 6503, and produce H i maps of considerably higher quality than previous observations by van Moorsel and Wells. We find that the velocity field, while remarkably regular, contains clear evidence for irregularities. The H i is distributed over an area much larger than the optical image of the galaxy, with spiral features in the outer parts and localized holes within the H i distribution. The absence of absorption toward the nearby quasar 1748+700 yields an upper limit of 5 × 1017 cm−2 for the column density of cold H i gas along a line of sight which should intersect the disk at a radius of 29 kpc. This suggests that the radial extent of the H i disk is not much larger than that which we trace in H i emission (23 kpc). The observed H i distribution is inconsistent with models of a single thin or thick disk. Instead, the data require a model containing a thin disk plus a thicker low column-density H i layer that rotates more slowly than the thin disk and that extends only to approximately the optical radius. This suggests that the presence of extraplanar gas in this galaxy is largely the result of star formation in the disk rather than cold gas accretion. Improved techniques for interferometric imaging including multi-scale Clean that were used in this work are also described.
