Geometric monitoring for CSI reduction in amplify-and-forward relay networks

This work studies the recently proposed geometric monitoring (GM) method in order to reduce the amount of necessary channel state information (CSI) in network (i.e., distributed) setups. Specifically, a network of amplify-and-forward (AF) relays is studied and the GM method is appropriately adapted. The basic idea is that GM could flag time instances where CSI exchange is unnecessary and, thus, the relay network could abstain from CSI exchange. It is found that, compared to alternative approaches, our GM approach can achieve significant CSI reduction in a variety of network setups.
Carcinoma of the lung in women

HE LITERATURE ABOUT CARCINOMA OF THE T lung contains many detailed studies of its pathology in men but few intensive studies of this neoplasm in women, probably because of its relatively infrequent occurrence in women. Mortality from lung cancer is 6.7 times more common among men than women in the white population of the United States.16 Most of the studies of cancer of the lung do not define specifically the criteria by which the original diagnoses were made; many consist of statistical or clinical data which have been collected from several hospitals. Histologic classification in these studies is of questionable validity because uniform histologic criteria were not used. More precise histologic classification is desirable, since Kreyberglo has related certain microscopic types of cancer of the lung to smoking, indicating a direct correlation between cigarette smoking and the frequency of Group I cancers of the lung. Group I tumors include squamous cell carcinoma and oat cell carcinoma. His Group I1 cancers are bronchiolar carcinoma, carcinoid tumors, salivary gland type tumors and adenocarcinomas. This study of pulmonary cancer defines the differences in the frequency of the various histological types in men and women. It includes all the cancers of the lung occurring in women at Barnes Hospital, St. Louis, Missouri, from 1947 to 1963.
Security Analysis of Industrial Test Compression Schemes

Test compression is widely used for reducing test time and cost of a very large scale integration circuit. It is also claimed to provide security against scan-based side-channel attacks. This paper pursues the legitimacy of this claim and presents scan attack vulnerabilities of test compression schemes used in commercial electronic design automation tools. A publicly available advanced encryption standard design is used and test compression structures provided by Synopsys, Cadence, and Mentor Graphics design for testability tools are inserted into the design. Experimental results of the differential scan attacks employed in this paper suggest that tools using X-masking and X-tolerance are vulnerable and leak information about the secret key. Differential scan attacks on these schemes have been demonstrated to have a best case success rate of 94.22% and 74.94%, respectively, for a random scan design. On the other hand, time compaction seems to be the strongest choice with the best case success rate of 3.55%. In addition, similar attacks are also performed on existing scan attack countermeasures proposed in the literature, thus experimentally evaluating their practical security. Finally, a suitable countermeasure is proposed and compared to the previously proposed countermeasures.
City Explorer: The Design and Evaluation of a Location-Based Community Information System

Many working professionals commute via public transit, yet they have limited tools for learning about their urban neighborhoods and fellow commuters. We designed a location-based game called City Explorer to investigate how transit commuters capture, share, and view community information that is specifically tied to locations. Through a four-week field study, we found that participants valued the increased awareness of their personal travel routines that they gained through City Explorer. When viewing community information, they preferred information that was factual rather than opinion-based and was presented at the start and end of their commutes. Participants found less value in connecting with other transit riders because transit rides were often seen as opportunities to disengage from others. We discuss how location-based technologies can be designed to display factual community information before, during, and at the end of transit commutes.
Emerging from the War : Current Accounts and the International Business Cycle 1885-1939 ∗

We study the dynamics of international business cycles and capital flows in the UK, the United States and the Emerging Periphery (Australia, Canada, Italy, Japan, Norway and Sweden) in the period 1885-1939. A simple intertemporal model of the current account with non-tradeable goods provides a surprisingly good characterization of the data under both the Classical Gold Standard and during the Interwar period. This holds true even though there are major changes in important business cycle moments between the two periods: i) output, current accounts and interest rates all become more volatile in the interwar period, ii) the standard deviation of current accounts declines relative to that of GDP and, iii) there are major shifts in the correlation between current accounts and output. We argue that these stylized facts are consistent with a model in which the transmission mechanism is fundamentally stable between the two periods but in which the underlying shocks become more persistent and more global: in the economies emerging from the war, global trend shocks are the main driver of output dynamics. Our results are robust to the exclusion of the Great Depression from the sample.

DSP based implementation of Sliding Mode Speed Controller for Vector Controlled Permanent Magnet Synchronous Motor drive

The paper deals with the performance analysis and hardware implementation of a sliding mode (SM) speed controller for vector controlled (VC) permanent magnet synchronous motor (PMSM) drive using a digital signal processor (DSP). The power circuit of the PMSM drive system consists of insulated gate bipolar transistor (IGBT) based voltage source inverter (VSI) and the gate driver circuit. The hardware of control circuit consists of current sensors and interfacing circuits. The reference speed, rotor speed estimation using sensed position signals, SM speed controller, reference frame transformation, vector controller and PWM current controller for the control of VSI feeding PMSM are implemented in assembly language of DSP-ADMC401. The simulation model of the PMSM drive system is developed in MATLAB environment with Simulink and PSB toolboxes to simulate the performance of the PMSM drive system. The simulated performance of the sliding mode controller (SMC) for speed control of PMSM drive is validated with test results for starting, speed reversal, load perturbation and steady-state running conditions.
Aortic reflecting distance and pulse wave velocity 1 Aortic Pulse Wave Velocity and Reflecting Distance Estimation from 1 Peripheral Waveforms in Humans : Detection of Age-and Exercise 2 Training-Related Differences 3 4

26 We hypothesized that demographic/anthropometric parameters can be used to estimate effective 27 reflecting distance (EfRD), required to derive aortic pulse wave velocity (APWV), a prognostic 28 marker of cardiovascular risk, from peripheral waveforms and that such estimates can 29 discriminate differences in APWV and EfRD with aging and habitual endurance exercise in 30 healthy adults. Ascending aortic pressure waveforms were derived from peripheral waveforms 31 (brachial artery pressure, n=25; and finger volume pulse, n=15) via a transfer function and then 32 used to determine the time delay between forwardand backward-traveling waves (Δtf-b). True 33 EfRDs were computed as directly measured carotid-femoral pulse wave velocity (CFPWV) x 34 1⁄2Δtf-b and then used in regression analysis to establish an equation for EfRD based on 35 demographic/anthropometric data (EfRD=0.173*age + 0.661*BMI + 34.548 cm; BMI: body 36 mass index). We found good agreement between true and estimated APWV (Pearson’s R=0.43; 37 intraclass correlation ICC=0.64; both P<0.05) and EfRD (R=0.24; ICC=0.40; both P<0.05). In 38 young sedentary (22±2 years, n=6), older sedentary (62±1 years, n=24), and older endurance39 trained (61±2 years, n=14) subjects, EfRD (from demographic/anthropometric parameters), 40 APWV, and 1⁄2Δtf-b (from brachial artery pressure waveforms) were 52.0±0.5, 61.8±0.4 and 41 60.6±0.5 cm; 6.4±0.3, 9.6±0.2, and 8.1±0.2 m/sec; and 82±3, 65±1 and 76±2 ms (all P<0.05), 42 respectively. Our results demonstrate that APWV derived from peripheral waveforms using age 43 and BMI to estimate EfRD correlates with CFPWV in healthy adults. This method can reliably 44 detect the distal shift of the reflecting site with age and the increase in APWV with sedentary 45 aging that is attenuated with habitual endurance exercise. 46
Evaluating a reactive semantics for robotics

A key part of programming a robotic system is specifying the responses to events that the robot may encounter. This is provided by a new language, RADAR. This paper proposes evaluating robot programming systems work by: a formalisation of the semantics, an evaluation in terms of criteria that determine a languagepsilas suitability for programming, and a small user study to test the readability of programs written using the semantics. The evaluation of the reactivity semantics found in the RADAR language shows clear benefits for programmers.
Word Alignment Based Parallel Corpora Evaluation and Cleaning Using Machine Learning Techniques

This paper presents a method for cleaning and evaluating parallel corpora using word alignments and machine learning algorithms. It is based on the assumption that parallel sentences have many word alignments while non-parallel sentences have few or none. We show that it is possible to build an automatic classifier, which identifies most of non-parallel sentences in a parallel corpus. This method allows us to do (1) automatic quality evaluation of parallel corpus, and (2) automatic parallel corpus cleaning. The method allows us to get cleaner parallel corpora, smaller statistical models, and faster MT training, but this does not always guarantee higher BLEU scores. An open-source implementation of the tool described in this paper is available from https://github.com/tilde-nlp/c-eval.
Fluxless bonding of Si chips to Ag-copper using electroplated indium and silver structures

In this study, we present fluxless bonding process between silicon and Ag-copper dual-layer substrate using electroplated In/Ag solder. We first study nucleation mechanism of electroplated In over Ag substrate. It is interesting to find that electroplated In reacts with underlying Ag to from AgIn2 IMC layer during electroplating. A novel laminating technique is developed on Cu substrate as cladding layer. The Ag cladding on the copper substrate is a buffer to deal with the large mismatch in coefficient of thermal expansion (CTE) between semiconductors such as Si (3ppm/°C) and Cu (17ppm/°C). To bond Si chips to the Ag layer on copper substrates, In-based alloy (InAg) is used. A fluxless bonding process is designed and developed between Si/Cr/Au/Ag and Cu/Ag/In/Ag. The bonding process is performed in 50-militorr vacuum atmosphere without any flux. The resulting joints consist of three distinct layers, i.e., Ag, Ag2In intermetallic compound and Ag layer. Microstructure and composition of the joints are studied using Scanning Electron Microscope (SEM) with energy dispersive X-ray spectroscopy (EDX). Annealing on the bonding samples is under way to change the three layer joint into two layers of (Ag) and Ag, which would have high re-melting temperature above 700°C. This technique presents our success in overcoming the very large mismatch in thermal expansion between silicon and copper. It can be applied to mounting numerous high power silicon devices to Cu substrate for various industry applications.
A High-Throughput Screening Assay for the Identification of Flavivirus NS5 Capping Enzyme GTP-Binding Inhibitors

There are no effective antivirals currently available for the treatment of flavivirus infection in humans. As such, the identification and characterization of novel drug target sites are critical to developing new classes of antiviral drugs. The flavivirus NS5 N-terminal capping enzyme (CE) is vital for the formation of the viral RNA cap structure, which directs viral polyprotein translation and stabilizes the 5′ end of the viral genome. The structure of the flavivirus CE has been solved, and a detailed understanding of the CE–guanosine triphosphate (GTP) and CE–RNA cap interactions is available. Because of the essential nature of the interaction for viral replication, disrupting CE–GTP binding is an attractive approach for drug development. The authors have previously developed a robust assay for monitoring CE–GTP binding in real time. They adapted this assay for high-throughput screening and performed a pilot screen of 46 323 commercially available compounds. A number of small-molecule inhibitors capable of displacing a fluorescently labeled GTP in vitro were identified, and a second functional assay was developed to identify false positives. The results presented indicate that the flavivirus CE cap-binding site is a valuable new target site for antiviral drug discovery and should be further exploited for broad-spectrum anti-flaviviral drug development.
HPV Type 6 and 18 Coinfection in a Case of Adult-Onset Laryngeal Papillomatosis: Immunization with Gardasil

Laryngeal papillomatosis (LP) is a rare human papillomavirus (HPV) related disease that often requires multiple surgical interventions and residual impairment of voice is almost inevitable. We report the case of a patient with adult onset recurrent LP, showing moderate dysplasia and coinfection with HPV types 6 and 18. The tetravalent HPV vaccine Gardasil was prescribed off label, with the aim of triggering an immunogenic response and consequently reducing the probability of further recurrences. The patient was followed for 9 months with no sign of relapse of his LP. The postexposure use of the anti-HPV vaccine could represent a promising therapeutic agent in established LP. Unfortunately, the potential efficacy of this new therapeutic option in this situation has been suggested only by isolated case reports. Further controlled studies, with a longer follow-up and a larger sample size, are needed to assess efficacy of Gardasil in LP.
Chronic playback of boat noise does not impact hatching success or post-hatching larval growth and survival in a cichlid fish

Anthropogenic (man-made) noise has been shown to have a negative impact on the behaviour and physiology of a range of terrestrial and aquatic animals. However, direct assessments of fitness consequences are rare. Here we examine the effect of additional noise on early life stages in the model cichlid fish, Neolamprologus pulcher. Many fishes use and produce sounds, they are crucial elements of aquatic ecosystems, and there is mounting evidence that they are vulnerable to anthropogenic noise; adult N. pulcher have recently been shown to change key behaviours during playback of motor boat noise. Using a split-brood design to eliminate potential genetic effects, we exposed half of the eggs and fry from each clutch to four weeks of playbacks of noise originally recorded from small motor boats with the other half acting as a control (receiving no noise playback). There was no significant effect of additional noise on hatching success or fry survival, length or weight at the end of the exposure period. Although care should be taken not to generalize these findings on a single species from a laboratory study, our data suggest that moderate noise increases do not necessarily have direct negative impacts on early-life survival and growth. Further studies on a range of species in natural conditions are urgently needed to inform conservation efforts and policy decisions about the consequences of anthropogenic noise.
Significance of expression of heat shock protein90alpha in human gastric cancer.

AIM To evaluate the significance of hsp90alpha expression in human gastric cancer tissues. METHODS Immunohistochemical staining was used in clinical specimens from 33 cases of gastric cancer and 33 cases of gastritis with rabbit anti-human hsp90alpha multi-clonal antibody in order to explore the relationship between the expression of hsp90alpha in gastric carcinoma tissue and gastritis tissue as well as in mucous membrane adjacent to cancer and lymph node metastasis. RESULTS Hsp90alpha was detected in 88% of gastric carcinoma cases and 55% of gastritis cases. The hsp90alpha positive rate in gastric cancer group was significantly higher than that in gastritis group (P<0.01, P=0.005). The hsp90alpha positive rate in gastric cancer and in mucous membrane adjacent to cancer was 88% and 55% respectively (P<0.01, P=0.005). The hsp90alpha positive rate in lymph node metastasis group and non-lymph node metastasis group was 100% and 60% respectively, and a significant correlation between hsp90alpha expression and lymph node metastasis was shown (P<0.01, P=0.005). CONCLUSION The hsp90alpha expression rate in gastric cancer group was significantly higher than that in gastritis group as well as that in the group of mucous membrane adjacent to cancer. The hsp90alpha expression in lymphatic node metastasis group was higher than that in non-lymphatic node metastasis group. The results indicate that increased hsp90alpha expression has a close relationship with occurrence and lymph node metastasis of gastric cancer.
DeepPurple: Estimating Sentence Semantic Similarity using N-gram Regression Models and Web Snippets

We estimate the semantic similarity between two sentences using regression models with features: 1) n-gram hit rates (lexical matches) between sentences, 2) lexical semantic similarity between non-matching words, and 3) sentence length. Lexical semantic similarity is computed via co-occurrence counts on a corpus harvested from the web using a modified mutual information metric. State-of-the-art results are obtained for semantic similarity computation at the word level, however, the fusion of this information at the sentence level provides only moderate improvement on Task 6 of SemEval'12. Despite the simple features used, regression models provide good performance, especially for shorter sentences, reaching correlation of 0.62 on the SemEval test set.
Electrophysiological Signature Reveals Laminar Structure of the Porcine Hippocampus

Visual Abstract The hippocampus is integral to working and episodic memory and is a central region of interest in diseases affecting these processes. Pig models are widely used in translational research and may provide an excellent bridge between rodents and nonhuman primates for CNS disease models because of their gyrencephalic neuroanatomy and significant white matter composition. However, the laminar structure of the pig hippocampus has not been well characterized. Therefore, we histologically characterized the dorsal hippocampus of Yucatan miniature pigs and quantified the cytoarchitecture of the hippocampal layers. We then utilized stereotaxis combined with single-unit electrophysiological mapping to precisely place multichannel laminar silicon probes into the dorsal hippocampus without the need for image guidance. We used in vivo electrophysiological recordings of simultaneous laminar field potentials and single-unit activity in multiple layers of the dorsal hippocampus to physiologically identify and quantify these layers under anesthesia. Consistent with previous reports, we found the porcine hippocampus to have the expected archicortical laminar structure, with some anatomical and histological features comparable to the rodent and others to the primate hippocampus. Importantly, we found these distinct features to be reflected in the laminar electrophysiology. This characterization, as well as our electrophysiology-based methodology targeting the porcine hippocampal lamina combined with high-channel-count silicon probes, will allow for analysis of spike-field interactions during normal and disease states in both anesthetized and future awake behaving neurophysiology in this large animal.
Locating Segments with Drums in Music Signals

A system is described which segments musical signals according to the presence or absence of drum instruments. Two different yet approximately equally accurate approaches were taken to solve the problem. The first is based on periodicity detection in the amplitude envelopes of the signal at subbands. The band-wise periodicity estimates are aggregated into a summary autocorrelation function, the characteristics of which reveal the drums. The other mechanism applies straightforward acoustic pattern recognition approach with mel-frequency cepstrum coefficients as features and a Gaussian mixture model classifier. The integrated system achieves 88 % correct segmentation over a database of 28 hours of music from different musical genres. For the both methods, errors occur for borderline cases with soft percussive-like drum accompaniment, or transient-like instrumentation without drums.
Phosphotyrosine-Dependent Coupling of Tim-3 to T-Cell Receptor Signaling Pathways

ABSTRACT The transmembrane protein Tim-3 has been shown to negatively regulate T-cell-dependent immune responses and was recently demonstrated to be associated with the phenomenon of immune exhaustion, which can occur as a consequence of chronic viral infection. Unlike other negative regulators of T-cell function (e.g., PD-1), Tim-3 does not contain any obvious inhibitory signaling motifs. We have found that ectopic expression of Tim-3 in T cells leads to enhancement of T-cell receptor (TCR)-dependent signaling pathways, which was observed at the level of transcriptional reporters and endogenous cytokine production. We have exploited this observation to dissect what elements within the cytoplasmic tail of Tim-3 are required for coupling to downstream signaling pathways. Here we have demonstrated that two of the more membrane-proximal cytoplasmic tail tyrosines are required for Tim-3 signaling to T-cell activation pathways in a redundant fashion. Furthermore, we show that Tim-3 can directly bind to the Src family tyrosine kinase Fyn and the p85 phosphatidylinositol 3-kinase (PI3K) adaptor. Thus, at least under conditions of short-term stimulation, Tim-3 can augment T-cell activation, although this effect can be blocked by the inclusion of an agonistic antibody to Tim-3. These findings should help further the study of Tim-3 function in other physiological settings, such as those that lead to immune exhaustion.
