Cross-layer optimal policies for stochastic reliable transmission in Wireless Sensor Networks

In Wireless Sensor Networks (WSNs), stochastic reliable transmission protocols, which improve reliability of the delivery process by transmitting redundant packets, have been proved to have advantage of energy efficiency over the retransmission one. But the burst and deep fading characteristic of the error prone wireless links in WSNs reduces the practicability of this kind of protocols. To solve this problem, a Markov Decision Process (MDP) based optimal scheduling algorithm is exploited in our work. Perfect channel state information (CSI) and cross-layer designs are combined artfully in the sequential decision process to make the protocol channel-adaptive. The objective of the optimization is to minimize the average energy consumption of the delivery process with constrained of desired delivery probability. The optimal policy which is proved to be monotone in accumulative successful probability and buffer state is computationally efficient and inexpensive to implement. Numerical examples are presented to evaluate the performance of the proposed strategy. The results demonstrate the superiority of our optimal policies over original scheme.
Non-Linearities in Specialization and Growth

This paper investigates the link between overall specialization and growth, analyzing the shape of the relationship between the median of the sectoral distribution of the Balassa Index, our summary measure of overall specialization, and the level of per capita income. The median of the Balassa Index distribution has an inverse relation with overall specialization. We analyze the specialization pattern of different countries employing three nonparametric methods: Kernel smoothing, lowess, and rolling regressions procedures. The empirical evidence suggests a non-linear relationship between countries' level of overall specialization and per capita income. We interpret such a non-linear relationship as the result of the different influence that the level of per capita income on one hand, and the existence of country-specific effects on the other, may have on sectoral diversification, according to the stage of development of a country.
On-line Flagging of Anomalies and Adaptive Sequential Hypothesis Testing for Fine-feature Characterization of Geosynchronous Satellites

Abstract : The objective of on-line flagging in this paper is to perform an interactive assessment of geosynchronous satellites anomalies such as cross-tagging of satellites in a cluster, solar panel offset change, etc. This assessment will utilize a Bayesian belief propagation procedure and will include an automated update of the baseline signature data for the satellite, while accounting for the seasonal changes. Its purpose is to enable an ongoing, automated assessment of satellite behavior through its life cycle using the photometry data collected during the synoptic search performed by a ground or space-based sensor as a part of its metrics mission. The change in the satellite features will be reported along with the probabilities of type I and type II errors. The objective of adaptive sequential hypothesis testing in this paper is to define future sensor tasking for the purpose of characterization of fine features of the satellite. The tasking will be designed in order to maximize new information with the least number of photometry data points to be collected during the synoptic search by a ground or space-based sensor. Its calculation is based on the utilization of information entropy techniques. The tasking is defined by considering a sequence of hypotheses in regard to the fine features of the satellite. The optimal observation conditions are then ordered in order to maximize new information about a chosen fine feature. The combined objective of on-line flagging and adaptive sequential hypothesis testing is to progressively discover new information about the features of geosynchronous satellites by leveraging the regular but sparse cadence of data collection during the synoptic search performed by a ground or space-based sensor.
3-D face analysis and identification based on statistical shape modelling

This paper presents an effective method of statistical shape representation for automatic face analysis and identification in 3-D. The method combines statistical shape modelling techniques and the non-rigid deformation matching scheme. This work is distinguished by three key contributions. The first is the introduction of a new 3-D shape registration method using hierarchical landmark detection and multilevel B-spline warping technique, which allows accurate dense correspondence search for statistical model construction. The second is the shape representation approach, based on Laplacian Eigenmap, which provides a nonlinear submanifold that links underlying structure of facial data. The third contribution is a hybrid method for matching the statistical model and test dataset which controls the levels of the model’s deformation at different matching stages and so increases chance of the successful matching. The proposed method is tested on the public database, BU-3DFE. Results indicate that it can achieve extremely high verification rates in a series of tests, thus providing real-world practicality.

ITLinQ+: An improved spectrum sharing mechanism for device-to-device communications

Device-to-device (D2D) communication enables proximity-based applications by exchanging information directly between nearby devices without routing through the cellular infrastructure. In this work, we propose a low-complexity distributed link scheduling and power control mechanism (ITLinQ+) for spectrum sharing in D2D networks, inspired by recent findings showing that power control and treating interference as Gaussian noise achieves rates close to the information-theoretic capacity region of the underlying interference channel under some conditions on the channel strengths. We show that ITLinQ+ substantially improves the average sum-throughput over other state-of-the-art schemes, such as FlashLinQ and the recently proposed ITLinQ. In particular, the new scheme provides large gains in terms of power efficiency.
Real-time optimal power flow under wind energy penetration-Part I: Approach

Real-time optimal power flow (RT-OPF) under wind energy penetration is highly desired but extremely difficult to realize. This is basically due to the conflict between the fast changes in wind power generation and the slow response from the optimization computation. This paper (Part I) presents a prediction-updating approach to address this challenge. We consider essential scenarios around forecasted data of wind power that would probably happen during the computation time required for solving a large-scale complex optimal power flow problem. Parallel computing is used to solve the individual OPF problems corresponding to these scenarios. This provides for the forecasted time horizon probable reference operations in the form of a lookup-table. One of these operations will be selected based on the actual wind power and realized to the grid for the current time interval, thus leading to a RT-OPF framework. The proposed approach is implemented in Part II of this paper using a 41-bus medium-voltage distribution network as a case study.
LiteMWBAN: A lightweight middleware for wireless body area network

Healthcare is considered as one of the most important agenda to address by many countries worldwide. Thanks to the recent development in wireless sensor technology, a continuous medical monitoring of the patients under their natural physiological states has been made possible and this will certainly help to detect transient life threatening from daily activities. With the growing variety of healthcare sensor devices, it is of interest to deploy a middleware system that shields the underlying technology differences from the application layer. The aim of this paper is to propose LiteMWBAN, a lightweight middleware for wireless medical body area network. The main features of the proposed middleware include support on: (i) multiple sensors and applications, (ii) plug and play, (iii) resource management and alert, and (iv) mobile applications. The prototype of the middleware has been built and its effective uses when deployed with a mobile healthcare application are shown in this paper.
Mountain Pygmies of Western New Guinea: A Morphological and Molecular Approach

Abstract The presence of “pygmy” or pygmoid groups among New Guinea populations has been the object of scientific interest since the end of the nineteenth century. Morphological and molecular data are used here to study western New Guinea population variability, focusing in particular on two pygmoid groups living in the eastern fringe highlands of Papua: the Una and the Ketengban. Various kinds of anthropometric data are examined, as well as height, weight, and body mass index, to carry out comparisons with nearby ethnic groups living in the highland and lowland regions. The Ketengban data were also compared with other data recorded 20 years before. The results of previous research on the sequencing of the mitochondrial DNA hypervariable segment 1 region and nuclear DNA nonrecombining Y-chromosome polymorphisms are presented. Both morphological and molecular studies involve adult subjects of both genders, representative of the same ethnic groups and/ or geographic regions. The pygmoid groups turn out to be significantly different from all other study groups, due to their small size, as confirmed by analysis of variance, although significant height and weight increments are observed with respect to those previously recorded. However, putative neutral genetic variation estimated from mitochondrial DNA and Y-chromosome markers support a recent shared common history between these pygmoid populations and the other central Papua groups (except for the Dani-Lani). These findings suggest that the short-stature phenotype is an independent secondary adaptation, possibly driven by an iodine-deficient environment, which leaves the potential for further investigations.
A Labelled Corpus for Prepositional Phrase Attachment

This paper describes a labelled corpus intended for training learning algorithms to attach prepositional phrases (PPs). Taken from the PTB2, we believe it is the largest available resource for this purpose, especially as it contains many patterns in which PPs occur ambiguously (nearly all previous research has focused on just one pattern) and we present some results for the five most common patterns. Moreover, the corpus contains some features that, to our knowledge, have not been used before for attaching PPs.
A test structure for two-dimensional analysis of MOSFETs by hot-carrier-induced photoemission

A test structure and method for two-dimensional analysis of fabrication process and reliability of MOSFET using a photoemission microscope are presented. Arrays of 20/spl times/10(=200) MOSFETs were successfully measured at a time and evaluated the fluctuation of their characteristics. The fluctuation of hot-carrier-induced photoemission intensity was larger as gate length becomes smaller. Although the intensity fluctuation of photoemission in the same MOSFET was within small range, the fluctuation all over the MOSFET array was relatively large and independent of the position in the array.
Novel Peptidyl Aryl Vinyl Sulfones as Highly Potent and Selective Inhibitors of Cathepsins L and B

Herein we present the design, synthesis, and evaluation of a structurally novel library of 20 peptidyl 3‐aryl vinyl sulfones as inhibitors of cathepsins L and B. The building blocks, described here for the first time, were synthesized in a highly efficient and enantioselective manner, starting from 3‐aryl‐substituted allyl alcohols. The corresponding vinyl sulfones were prepared by a new approach, based on a combination of solid‐phase peptide synthesis using the Fmoc/tBu strategy, followed by solution‐phase coupling to the corresponding (R)‐3‐amino‐3‐aryl vinyl sulfones as trifluoroacetate salts. The inhibitory activity of the resulting compounds against cathepsins L and B was evaluated, and the compound exhibiting the best activity was selected for enzymatic characterization. Finally, docking studies were performed in order to identify key structural features of the aryl substituent.
Clinical outcome of patients with subcutaneous panniculitis-like T-cell lymphoma

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a rare form of cytotoxic T-cell lymphoma. The objective of this study was to characterize the clinical presentation, treatment, and prognosis of patients with SPTCL. Twenty-one patients with SPTCL were seen at Mayo Clinic (Rochester, Minnesota, USA) between July 1973 and June 2004. The median age at diagnosis was 42 years (range 23-80 years) and 15 (71%) were women. Constitutional symptoms occurred in 14 (67%) patients, including fever, serositis, arthralgias and myalgias. The Eastern Cooperative Oncology Group performance score was poor (3-4) in 3 (15%) patients. Liver enzymes (at least 2 enzymes, Aspartate aminotransferase (AST), alkaline phosphatase and/or lactate dehydrogenase) were elevated in 11 (52%) patients. Therapy consisted of chemotherapy in 13 (62%) patients, or other therapeutic interventions in 8 (38%) patients, including surgical excision, corticosteroids alone or in combination with either plaquenil, colchicine, hydroxychoroquine, or azathioprine. Bone marrow transplantation was performed in 5 (24%) patients, 3 autologous and 2 allogeneic. The median overall survival from diagnosis was 15 months (range 0.1-104 months). Two groups of patients were identified and categorized as having a favorable or unfavorable disease course. The factors associated with an unfavorable disease course were a low white blood cell count or elevated lactate dehydrogenase. Patients treated aggressively with stem cell transplantation appeared to have an improved overall survival.
Area Division Based Semi-auto DV-Hop Localization algorithm in IEEGS

Wireless sensor networks (WSNs) have been listed as one of the most influential technology in the 21st century. “Indoor Emergency-escape-guide System (IEEGS)” is an application system based on WSNs for fire monitoring and escapes guiding. Nodes' positions have significant meaning to IEEGS. We proposed a new localization algorithm for IEEGS which is based on DV-Hop and named as ADBSA DV-Hop. We used several ideas including semi-auto average size of per hop obtaining, area division, and sticking to border in ADBSA DV-Hop. Compared ADBSA DV-Hop with DV-Hop through simulation, the results we got indicated that ADBSA DV-Hop performed better than DV-Hop, and competently met the localization requirements of IEEGS.
Depression, Optimism, and Positive Health Practices in Young Adolescents

Correlations among depression, optimism, and positive health practices were studied in young adolescents. A sample of 131 boys and girls, aged 12 to 14 (M = 13.2, SD = .8) completed the Revised Personal Lifestyle Questionnaire, the Center for Epidemiological Studies–Depression Scale, and the Life Orientation Test. A negative correlation (–.47) was found between scores on Depression and Positive Health Practices, and the correlation for scores on Optimism and Positive Health Practices was . 52.
Severe Broca’s Aphasia without Broca’s Area Damage

Although sub-cortical aphasia is a common neurological disorder, its neural basis is not clear. Recent evidence suggests that hypoperfusion of the cortical language areas may be the primary culprit [1,2]. That is, the subcortical lesion – often including the left striatocapsular region – is associated with decreased cerebral blood flow in the cortex causing impaired language processing. Another account of sub-cortical aphasia suggests that the language impairment is caused by disconnection of the cortical language areas [3]. According to this account, the neurophysiological status of the language areas would be intact but the necessary communication between these areas would be disrupted. Here we present a case of sub-cortical aphasia which would support this latter explanation. This 32 year old patient suffered a subcortical hemorrhagic stroke during child birth (Fig. 1). Although fMRI showed increased activity in her Broca’s area and left middle temporal lobe during an overt picture naming task, it was clear from the tractography that the anterior and posterior language areas were disconnected as white matter tracts originating in Broca’s area were not reaching the posterior language areas via the arcuate fasciculus (Fig. 2). This was not the case for the contralateral hemisphere where increased brain activity was noted in the homologues of the anterior and posterior language areas. Although auditory comprehension was relatively intact, this patient presented with se-
A selective morpho-phonological deficit?

ABSTRACT We report on an English-speaking, aphasic individual (TB) who showed a striking dissociation in speaking with the different forms (allomorphs) that an inflection can take. Although very accurate in producing the consonantal inflections (-/s/, -/z/, -/d/, -/t/), TB consistently omitted syllabic inflections (-/əz/, -/əd/), therefore correctly saying “dogs” or “walked,” but “bench” for benches or “skate” for skated. Results from control tests ruled out that TB’s selective difficulties stemmed from problems in selecting the correct inflection for the syntactic context or problems related to phonological or articulatory mechanisms. TB’s selective difficulties appeared instead to concern morpho-phonological mechanisms responsible for adapting morphological elements to word phonology. These mechanisms determine whether the plural inflection surfaces in the noun bench as voiced (-/z/), unvoiced (-/s/) or syllabic (-/əz/). Our results have implications for understanding how morphological elements are encoded in the lexicon and the nature of morpho-phonological mechanisms involved in speech production.
Signal and noise separation in medical diagnostic system based on independent component analysis

The possibility to study graphic recording (PCG -Phonocardiography) of auscultator findings is a helpful diagnostic tool for the clinician and forms the basis of early detection of the heart problems. Due to its dispersed nature and overlapping with breathing sounds Heart Sound Signals (HSS) is difficult to detect and comprehend in conventional PCG. We present a Hardware system utilizing Frequency-Domain Independent Component Analysis (ICA) deploying Direction of Arrival (DOA) and Beamforming (BF) techniques for the suppression of noise which will enhance the quality of HSS and aid the physicians. Such techniques of HSS extraction have been rarely studied in the past.
Low density generator matrix codes for bit-interleaved coded modulation

A bit-interleaved coded modulation with iterative decoding (BICM-ID) is proposed using a serial concatenation of two low-density generator matrix (LDGM) codes. The performance of this scheme is analyzed via computer simulations over both AWGN and Rayleigh fading channels for various signaling methods. The results show the ability of the proposed scheme to perform near the Shannon capacity limits.

An LMI approach to design extended predictor feedback controllers for dynamical systems with input delay

ABSTRACT The stabilisation of dynamical systems with input delay by an extended predictor feedback controller is investigated. After considering a more general case of the predictor feedback controllers, the design procedure is transformed into the stabilisation problem of the system controlled by a dynamic output feedback controller. By proposing appropriate Lyapunov-Krasovskii functionals, the predictor feedback gains are then synthesised from the stability conditions which are obtained in form of linear matrix inequalities. Such design approach is more flexible and extendable in comparison to one used by the conventional predictor feedback control. As a simulation example, the designed extended predictor feedback controller is applied on an active suspension system and is used to stabilise an unstable system with input delays. The obtained results demonstrate the effectiveness of the design method.
Efficacy and Safety of Recombinant Human Thrombopoietin on Sepsis Patients With Thrombocytopenia: A Systematic Review and Meta-Analysis

Background The efficacy and safety of the administration of recombinant human thrombopoietin (rhTPO) in sepsis patients with thrombocytopenia were still inconclusive. Objectives To investigate whether rhTPO is a benefit for sepsis patients with thrombocytopenia. Methods PubMed, Cochrane library, Embase, China National Knowledge Infrastructure, and Wanfang Database were electronically searched to the randomized controlled trials (RCTs) from inception to March 4, 2020. The primary outcome was the level of platelet (PLT) on the 7th day of treatment, and secondary outcomes were 28-d mortality, the level of coagulation indicators, hepatic and renal function indicators, blood transfusion, and length of intensive care unit (ICU) stay. Results Ten RCTs involving 681 patients were included. For compared with conventional antibiotic therapy, rhTPO could significantly increase platelet counts (PCs) [standardized mean difference (SMD), 2.61; 95% confidence interval (CI), 1.28–3.94; P < 0.001], decreased 28-d mortality [relative risk (RR), 0.66; 95%CI, 0.46–0.97; P=0.03], transfusion volume of blood products and length of ICU stay. Additionally, for compared with conventional antibiotic therapy combined with intravenous immunoglobulin, the pooled results shown that rhTPO also associated with an improvement of PCs on 7th of treatment (SMD, 0.86; 95%CI, 0.54–1.17; P < 0.001), and a reduced transfusion volume of blood products. However, there were no differences in 28-d mortality and the length of ICU stay. Conclusions Current evidence shown that rhTPO could increase PCs on 7th day of treatment and reduce the transfusion volume of blood products in sepsis-related thrombocytopenia during hospitalization. The conclusions are needed to be verified indeed by more multicenter RCTs due to the limitation of the included studies.
