A Base Station DTX Scheme for OFDMA Cellular Networks Powered by the Smart Grid

Discontinuous transmission (DTX) is an efficient technology to improve the energy efficiency of the wireless cellular networks. DTX enables the deactivation of some components of the base station in sufficient short time, which can decrease the energy consumption without affecting the normal operation of the mobile networks. In addition, we consider distributed smart grid which can power the cellular networks using renewable and conventional energy. The distributed smart grid has many different energy retailers with variant energy resource, such as solar energy, wind energy, and conventional energy. Comparing with conventional energy, the renewable energy is more environmental friendly, but more expensive. As a result, it is necessary to obtain a good tradeoff between the operation cost and greenhouse gas (GHG) emission. In this paper, we jointly optimize the DTX, resource allocation, and smart grid energy procurement to maximize the profit of the network operators and minimize the GHG emission. We formulate the joint optimization problem as a mixed integer programming problem. By exploiting the structure of the coupled constraint of the problem, we propose a suboptimal distributed algorithm based on the Lagrangian dual method, and the algorithm can be performed at cellular network and smart grid alternately, which can significantly decrease the signaling and computational overhead. Simulation results illustrate that the proposed DTX scheme can significantly enhance the energy saving, and further improve the energy efficiency of the cellular networks.
Interpretable Semantic Textual Similarity for Indonesian Sentence

We develop iSTS (Interpretable Semantic Textual Similarity) model to Indonesian corpus. System of iSTS is not only to represent the STS (Semantic Textual Similarity) score but also to give an explanation of the semantic similarity of the pair of sentence. The term of explanation refers to a pair of chunks with type such as EQUI, OPPO, SPE1, SPE2, REL, SIMI, NOALI and score ranged 0 to 5. Nowadays, iSTS corpus has not existed in the Indonesian version yet, by that mean we build that corpus. We adapt two best iSTS techniques for English corpus: VRep and UWB. VRep uses WordNet to representing word semantic, while UWB uses word embedding. Both of the techniques use similar process, such as preprocess, feature extraction, and classification. The adaptation of VRep and UWB on this research is performed by changing English resources in Indonesia such as WordNet, word embedding, etc. We also use four classifier as well as decision tree, SVM, random forest, and multilayer perceptron. VRep becomes the best model on type aspect and score aspect, while UWB becomes the best model on type + score aspect.
Manipulator control with image-based visual servo

A visual feedback control scheme, called image-based visual servo, is proposed for manipulators with cameras on their hands. To accomplish specific tasks in unstructured environments, it is essential to have capabilities of recognizing the object position with respect to the manipulator hand. Using the Jacobian matrix relating the camera motion to the object position change in the acquired image, a state space formulation of a visual feedback system is established. On the basis of the task defined in the image plane, the desired motion of the hand is achieved by time-variant state feedback. The image-based scheme is applied to a task of tracking a moving object by the camera (and the hand). Simulations show that the control scheme is stable even under noisy conditions, while the conventional position-based servo tends to be unstable. Experiments on a PUMA 560 show the validity and the effectiveness of the image-based visual servo. <<ETX>>
New technologies for improving spatial resolution of satellite images

In this paper, the results of different image fusion schemes for pixel level fusion and image super-resolution reconstruction algorithm are presented. A new method that performs enhancements in the spatial resolution is employed. It has the following unique features: (a) higher ability of improving image spatial resolution (b) increased reduction of pixel uncertainties due to calibration errors through a new adaptive filtering technique, and (c) improved reduction of the blurring through a new blur estimation and super-resolution restoration that employs cross-validation for regularization. Tradeoff studies with other state of the art spatial resolution enhancement algorithms are presented.
Dual Push–Pull High-Speed Rail-to-Rail CMOS Buffer Amplifier for Flat-Panel Displays

This brief presents the experimental validation of a low-power, large output swing, class-AB buffer amplifier for column drivers of active-matrix flat-panel displays. By exploiting two complementary input amplifiers and a dual-path push–pull output stage, the proposed circuit achieves high-drive performance and rail-to-rail operation. In addition, two current boosters allow area optimization of the output diving transistors by dynamically lowering their threshold voltage. Implemented in a standard triple-well CMOS 0.35-<inline-formula> <tex-math notation="LaTeX">${\mu }{\text{m}}$ </tex-math></inline-formula> technology and supplied from a 3-V supply, the proposed buffer amplifier can drive a 1-nF column line load within a 1.11-<inline-formula> <tex-math notation="LaTeX">${\mu }\text{s}$ </tex-math></inline-formula> settling time under a full voltage swing, while drawing only 1.6 <inline-formula> <tex-math notation="LaTeX">${\mu }\text{A}$ </tex-math></inline-formula> quiescent current and occupying 5562 <inline-formula> <tex-math notation="LaTeX">${\mu }{\text{m}}^{{2}}$ </tex-math></inline-formula> of silicon area. As compared to the state of the art, the best figure of merit (pF/<inline-formula> <tex-math notation="LaTeX">${\mu }\text{s}{\cdot } {\mu }\text{A}$ </tex-math></inline-formula>) is found.
“Human Cock Fighting”: The Culturally Acceptable Ritual of Violence in Sports

As Eric Arthur Blair, a British author and journalist (known by his pen name, George Orwell), used to say: “serious sport has nothing to do with fair play, it is war without shooting”. Ancient Mesoamericans had their ball games, the Greeks had the Olympic Games, and the Romans had many spectator sports such as gladiatorial contests and chariot races. Economically speaking, US sports industry generated over $400 billion during 2010, with the big four US professional leagues generating almost $22 billion [1]. People watch sports for different reasons. For some spectators, sporting events simply provide entertainment, while for others it helps to attenuate the everyday tension. In addition, watching sports can be seen as a social activity, in which individuals of similar cultural or national backgrounds gather to have a community experience [2].
Klinische Ergebnisse mit Dronedaron (Multaq®) bei nicht-permanentem Vorhofflimmern - Resultate des DEMETER-Registers

Clinical Results with Dronedarone (MULTAQ) in non-permanent Atrial Fibrillation – Results of the DEMETER Registry. Introduction: Dronedarone (Multaq®, Sanofi) is a multi-channel blocker used for drug therapy in non-permanent atrial fibrillation (AF). In Austria this antiarrhythmic agent is available since 02/2010. We report the clinical results of the prospective DEMETER registry (02/2010– 12/2011). Methods: Six Austrian hospitals added 94 patients to the study (ambulatory or stationary). Inclusion criteria were first time AF (2.2%), paroxysmal AF (72.3%), persistent AF (24.4%) and longstanding persistent AF (1.1%). ECG parameters (rhythm, heart rate, PR, QTc), laboratory findings (renal and hepatic parameters), NYHA stages, CHADS2 scores and echocardiographic data (LVEF and atrial diameters) were recorded at baseline (BL) and reevaluated after 3 and 6 month including quality of life (QoL) concerning AF. Results: 55% of all patients were able to complete the study compliant to the protocol, 20% were lost to follow-up and discontinuation was documented in 15% of pts. Recurrent AF was the main reason for termination (75%). Proarrhythmic effects or deaths were not observed. Rehospitalisation rate was low (8.3%) and limited to recurrent AF. Over a period of 6 month there was no relevant progression of sinus rhythm (SR) into persistent AF, liver and renal function remained stable. Relevant changes in ECG parameters could not be observed, NYHA stages decreased from visit to visit and patients expressed a significant better QoL right from the first follow-up (FU1). Conclusions: Concerning symptoms, ECG, renal and hepatic parameters, Dronedarone seems to be safe and well tolerated with infrequent side effects, significantly decreasing clinical heart failure (p = 0.0001) and improving QoL (p = 0.013) in hemodynamically stable patients suffering from non-permanent AF. A high lost to follow-up proportion of 45% limits the explanatory power of the registry. J Kardiol 2015; 22 (Pre-Publishing Online)
Effects of Sequential Participation in Evidence-Based Health and Wellness Programs Among Older Adults

Abstract Background and Objectives Evidence suggests participation in evidence-based programs by older adults is effective, yet most studies focus on participation in a single evidence-based program, leaving repeated participation insufficiently understood. We aimed to compare participation in multiple evidence-based programs (repeaters) versus a single evidence-based program (nonrepeaters). Research Design and Methods Secondary data analysis was conducted on pre–post longitudinal data targeting older adults participating in evidence-based program(s) in Texas (2013–2016). Surveys included sociodemographic and health-related indicators (e.g., self-rated health, health behaviors, and falls-risks). Mixed-effects models examined pre–post changes in health-related indicators. Results Of the 734 study-eligible participants, 145 (20%) participated in two or more evidence-based programs. The participants’ average age was 74 years, and the majority was female (80%), non-Hispanic White (79%), or lived in urban or large rural cities/towns (79%). At baseline, repeaters reported less depressive symptomology (p = .049), fewer chronic conditions (p = .048), and less concern of falling (p = .030) than nonrepeaters. Repeaters had better workshop attendance and completion rates (p < .001). Compared to nonrepeaters, repeaters showed significantly-better improvements in communication with physicians (p = .013). Discussion and Implications Study findings suggest potential benefits of participation in multiple evidence-based program workshops, but repeaters may have different health profiles than nonrepeaters in natural settings. Future evaluations should consider participants’ past participations in evidence-based programs. Further research is needed to build more comprehensive evidence about the incremental benefits of participation in multiple evidence-based programs.
An Investigation of Heart Disease Prediction Techniques

Heart disease indicates the type of condition which leads to heart malfunction. Not all people with coronary artery disease have chest pain as a symptom. There are other factors such as R-Blood Pressure, S-Cholesterol, F-Blood Sugar, R-ECG, Thalach, Ex-Ang, Number of major Vessels blocked, Thallium Scan which also results in heart disease. At an initial stage the prediction of heart disease can save human lives. Data mining techniques such as Naive Bayes, Decision Tree, K-nearest neighbor, etc., are used in the Heart Disease prediction based on the parameters / factors. The objective of this research is to investigate about the various factors and its significance in identifying the heart disease. Further it also explores about the existing techniques and models used for prediction. This work concludes with the key challenges which are not yet explored.
Energy Efficient Channel Accessing Protocol for Wireless Sensor Network

Wireless Sensor Networks (WSNs) consist of large number of sensors that are deployed in the network with some initial amount of energy. During long run of network, as the energy of the sensor gets drained, recharging it frequently is a difficult task. Thus, there exists a need to efficiently utilize the energy of sensors. To address this challenge, a variety of channel accessing protocols have been proposed. But the effect of starvation of nodes and their need to access the channel is less emphasized in any of them. In this paper, an Energy Efficient Channel Accessing protocol (EECA protocol) is proposed to reduce collisions between the nodes and address the above issues. As a part of EECA protocol, an algorithm is proposed to elect a manager node to schedule other contending nodes according to their priorities. Moreover, there is a high chance of new node to enter into the network which can be malicious. Thus in EECA protocol, Listen and Detect (LnD) method is also proposed for detection of the malicious node. The analysis and comparisons show that the energy consumption and starvation of nodes is considerably reduced in EECA protocol.
Multidimensional Effects of Soy Isoflavone by Food or Supplements in Menopause Women: A Systematic Review and Bibliometric Analysis

Isoflavones can exert their action on various levels: on cardiovascular system, bone and muscle health, on cancer, on menopausal symptoms, on obesity, on thyroid and on cognitive function. The aim of this systematic review is to evaluate the multidimensional effects of phytoestrogens in postmenopausal woman, and specifically to explore the impact on scientific literature. A research strategy was planned on PubMed and Scopus by defining the following key words:: menopause, climacteric, soy, isoflavone, phytoestrogens, cardiovascular system, bone mineral density, muscle mass, cancer, thyroid, obesity, cognitive. A total of 43 studies (in humans) were retrieved. The majority (12) describe the applications of soy isoflavones on cardiovascular disease, followed by effects on bone and muscle health (9), and studies concerning their action on menopausal symptoms (7), on cancer (6), on obesity (4), on cognitive function (3) and on thyroid function (2). The citation analysis revealed a growing interest for this topic and the papers on thyroid function are the most cited. Citation trends of the articles regarding the action on cardiovascular disease and on obesity are growing in the last years. Concerning the research areas, this review has assessed the effectiveness of various activities of isoflavones on welfare of menopausal women. In particular, literature show that a specific dosage of isoflavones reduces cardiovascular disease (from 20 to 100 mg/die), may be protective in osteoporosis and muscular fatigue (from 20 to 80 mg/die), may be useful for cancer prevention on endometrium, mammary glands and liver (from 50 to 100 mg/die), might improve menopausal symptoms, particularly in reducing the frequency of hot flashes (from 50 to 120 mg/die), can reduce abdominal fat and circulating inflammatory markers (from 80 to 160 mg/die), may ameliorate the possible interaction between endogenous estrogen and thyroid function (75 mg/die) and improve visual memory (from 50 to 100 mg/die).
Obesity and metabolic disorders in adults with lower limb amputation.

Anthropometric and biochemical research was conducted on 94 subjects with various levels of lower limb amputation. The purpose of the work was to investigate the features of obesity progression and disorders of cholesterin metabolism, as well as to develop adequate training exercises. Anthropometric research was conducted by calipermetry; the biochemical research was done by various methods to determine exempt and total cholesterin and triglycerides in the blood serum. The research establishes the frequency of obesity progression relative to the level of amputation, as well as the features of the excessive body mass. Type 11 A hyperlipoproteidemia a was evident. It is characterized by rapid progress of atherosclerotic vascular disease and coronary disease (CD). Cyclic and acyclic exercises were developed for prophylaxis and therapy. Anthropometric research on the determination of body fat mass was conducted on 68 subjects with various levels of lower limb amputation. The nondirect method of measuring skin folds of several parts of the body was used to determine the extent of lipogenesis. Biochemical research of cholesterin metabolism was conducted on 26 subjects with lower limb amputation (a different group). Anthropometric research revealed an increase of body fat mass directly related to the level of amputation. The largest amount of fat in the body mass was noted for the subjects with bilateral transfemoral (above-knee) amputation or transfemoral plus transtibial (below-knee) amputation. Both groups averaged 25.9%. The body fat mass increased chiefly in the subcutaneous fat. Increase of the internal fat mass was less noticeable. The frequency of obesity progression in subjects with unilateral transtibial amputation equaled 37.9%; in subjects with transfemoral amputation, 48.0%; and in subjects with bilateral transfemoral or transfemoral plus transtibial amputation, 64.2%. Young subjects demonstrated obesity progression during the first year after amputation. Biochemical research revealed changes in the cholesterin fractions typical for type 11 A hyperlipoproteidemia. This type of hyperlipoproteidemia is often accompanied by atherosclerotic vascular diseases and CD. On the basis of the research and clinical observation, exercises were developed aimed at prophylaxis and treatment of the revealed changes. Exercises are described for subjects with various levels of lower limb amputation when using exercise machines and when swimming.

P4Visor: lightweight virtualization and composition primitives for building and testing modular programs

Programmable data planes, PDPs, enable an unprecedented level of flexibility and have emerged as a promising alternative to existing data planes. Despite the rapid development and prototyping cycles that PDPs promote, the existing PDP ecosystem lacks appropriate abstractions and algorithms to support these rapid testing and deployment life-cycles. In this paper, we propose P4Visor, a lightweight virtualization abstraction that provides testing primitives as a first-order citizen of the PDP ecosystem. P4Visor can efficiently support multiple PDP programs through a combination of compiler optimizations and program analysis-based algorithms. P4Visor s algorithm improves over state-of-the-art techniques by significantly reducing the resource overheads associated with embedding numerous versions of a PDP program into hardware. To demonstrate the efficiency and viability of P4Visor, we implemented and evaluated P4Visor on both a software switch and an FPGA-based hardware switch using fourteen different PDP programs. Our results demonstrate that P4Visor introduces minimal overheads (less than 1%) and is one order of magnitude more efficient than existing PDPs primitives for concurrently supporting multiple programs.
A Correcting Model for Preposition Error in English Essays of Chinese Student Based on Hybrid Features Classification

In this paper, we propose an automatic preposition correction method for Chinese learners of English. Our corpus comes from Chinese learners of English Corpus (CLEC). We use N-gram model to extract the semantic features based on the form of the word in context, part of speech tagging and syntactic parse tree. Meanwhile, this paper proposes a new method based on mutual information and improves the training and classification method. This method’s performance has been improved in terms of both effectiveness and efficiency, and the results show a significant improvement compared with the previous results.
Designing ASCY-compliant Concurrent Search Data Structures

This report details the design of two new concurrent data structures, a hash table, called CLHT, and a binary search tree (BST), called BST-TK. Both designs are based on asynchronized concurrency (ASCY), a paradigm consisting of four complementary programming patterns. ASCY calls for the design of concurrent search data structures to resemble that of their sequential counterparts. CLHT (cache-line hash table) uses cache-line-sized buckets and performs in-place updates. As a cache-line block is the granularity of the cache-coherence protocols, CLHT ensures that most operations are completed with at most one cache-line transfer. BST-TK reduces the number of cache-line transfers by acquiring less locks than existing BSTs.
Demonstration of a GaN-Based Vertical-Channel JFET Fabricated by Selective-Area Regrowth

One of the key challenges for vertical GaN power devices is their complex fabrication process. We present the first experimental realization of a GaN-based vertical-channel junction field-effect transistor. A selective-area regrowth process was developed to epitaxially form the lateral p-n junction used for current control in the channel. First devices fabricated show an ${R}_{\mathrm{ON}}=\textsf {2.36}\,\,\text {m}\Omega \text {cm}^{{2}}$ and demonstrate basic current modulation. We discuss the device characteristics and limitations. Based on a TCAD model fitted to the experimental data, we explore the design rules for future device implementation.
Estudio de campo sobre la eficacia de la aplicación de dos modalidades clásicas de triple terapia antirretroviral

BACKGROUND: To compare the temporal evolution of viral load and CD4 parameters in two cohorts of HIV infected patients enrolled in classical triple antiretroviral regimens. METHODS: Retrospective, observational, descriptive study of the proportions of patients reaching undetectable levels of viral load (VL) as well as the time necessary to get it. The two cohorts were as follows: 91 HIV patients on triple therapy with zidovudine plus lamivudine and indinavir (cohort A) versus 80 HIV patients with Stavudine plus Didanosine and Indinavir (cohort B). RESULTS: The evolution of the patients in terms of percentages who reach undetectable VL was similar in the two therapeutic cohorts (75.8%for cohort A vs 73.8% for cohort B) along the duration of the study (four years). However, the mean time period needed to reach undetectable VL was different, 209 days (IC 95% 175-243 days) for patients in zidovudine plus lamivudine and indinavir and 330 days (IC 95% 263-396 days) for stavudine plus didanosine and indinavir regimen. The immunological status observed in the patients when reaching his first undetectable VL was significantly different. The proportion of patients with CD4 cells counts >200/mm3 in cohort A was 83.1% while for patients from cohort B was 65.4% (p=0.032). CONCLUSIONS: This observational study from clinical settings seems demonstrate similar efficacy to reach undetectable VL with both classical triple antiretroviral therapies evaluated but a shorter delay of time to reach that virological situation for zidovudine plus lamivudine and indinavir regimen is reported.
