Sentiment Lexicon Expansion Based on Neural PU Learning, Double Dictionary Lookup, and Polarity Association

Although many sentiment lexicons in different languages exist, most are not comprehensive. In a recent sentiment analysis application, we used a large Chinese sentiment lexicon and found that it missed a large number of sentiment words in social media. This prompted us to make a new attempt to study sentiment lexicon expansion. This paper first poses the problem as a PU learning problem, which is a new formulation. It then proposes a new PU learning method suitable for our problem using a neural network. The results are enhanced further with a new dictionary-based technique and a novel polarity classification technique. Experimental results show that the proposed approach outperforms baseline methods greatly.
Ieee Transactions on Aerospace and Electronic Systems 1 Quasi-orthogonal Wideband Radar Waveforms Based on Chaotic Systems *

Many radar applications, such as those involving multiple-input, multiple-output (MIMO) radar, require sets of waveforms that are orthogonal, or nearly orthogonal. As shown in this paper, a set of nearly orthogonal waveforms with a high cardinality can be generated using chaotic systems, and this set performs comparably to other waveform sets used in pulse compression radar systems. Specifically, the nearly orthogonal waveforms from chaotic systems are shown to possess many desirable radar properties including a compact spectrum, low range sidelobes, and an average transmit power within a few dB of peak power. Moreover, these waveforms can be generated at essentially any practical time length and bandwidth. Since these waveforms are generated from a deterministic process, each waveform can be represented with a small number of system parameters. Additionally, assuming these waveforms possess a large time-bandwidth product, a high number of nearly-orthogonal chaotic waveforms exist for a given time and bandwidth. Thus, the proposed generation procedure can potentially be used to generate a new transmit waveform on each pulse.

Synthesis, Anticancer and Radioprotective Activities of Some New Pyrazolo[3,4-d]pyrimidines Containing Amino Acid Moieties

Abstract Various isomeric structural purine analogues possessing the pyrazolo[3,4-d]pyrimidine nucleus bearing amino acid moieties have been synthesized. The structures of the synthesized compounds were elucidated by spectral data. Preliminary testing for in vitro anticancer activity of the synthesized compounds against Ehrlich ascites carcinoma cells was carried out. 2-(1-Phenyl-1H-pyrazolo[3,4-d]pyrimidin-4-ylamino)-propanoic acid (3b), 4-methyl-2-(1-phenyl-1H-pyrazolo[3,4-d] pyrimidin-4-ylamino)-pentanoic acid (3d), 4-methylthio-2-( 1-phenyl- 1H-pyra-zolo[3,4-d] pyrimidin-4-ylamino)-butanoic acid (3e) and phenyl-2-(1-phenyl-1H-pyrazolo[3,4-d] pyrimidin-4-ylamino)-propanoic acid (3f) were the most active compounds. Moreover, compounds 3e and 1-( 1-phenyl-1H-pyrazolo[3,4-d] pyrimidin-4-yl)-pyrrolidine-2-carboxylic acid (4) exhibited significant in vivo radioprotective activity.
Neural-network-based adaptive hybrid-reflectance model for 3-D surface reconstruction

This paper proposes a novel neural-network-based adaptive hybrid-reflectance three-dimensional (3-D) surface reconstruction model. The neural network automatically combines the diffuse and specular components into a hybrid model. The proposed model considers the characteristics of each point and the variant albedo to prevent the reconstructed surface from being distorted. The neural network inputs are the pixel values of the two-dimensional images to be reconstructed. The normal vectors of the surface can then be obtained from the output of the neural network after supervised learning, where the illuminant direction does not have to be known in advance. Finally, the obtained normal vectors are applied to enforce integrability when reconstructing 3-D objects. Facial images and images of other general objects were used to test the proposed approach. The experimental results demonstrate that the proposed neural-network-based adaptive hybrid-reflectance model can be successfully applied to objects generally, and perform 3-D surface reconstruction better than some existing approaches.
The short half-life of glucagon-like peptide-1 in plasma does not reflect its long-lasting beneficial effects.

The incretin hormone glucagon-like peptide-1 (GLP-1) is capable of ameliorating glucose-dependent insulin secretion in subjects with diabetes. However, its very short half-life (1.5-5 min) in plasma represents a major limitation for its use in the clinical setting. The present study was designed to characterize the duration of the effect of GLP-1 in the Zucker diabetic fatty (ZDF) rat. ZDF rats were subjected to a 48 h infusion of human GLP-1 (30 pmol/kg per min), followed by an i.p. glucose tolerance test (IPGTT) (1 g/kg body weight), 2 h after removing the infusion pump. At 15 min from the beginning of the test, GLP-1-treated animals had lower plasma glucose levels (442+/-38 mg/dl) than saline-infused controls (583+/-63 mg/dl, P<0.01). This was reflected in the higher insulin levels attained in the GLP-1-treated animals (1999+/-163 vs 1250+/-51 pmol/l, GLP-1 vs saline respectively, P<0.01). Repetition of the IPGTT on day 3, 9 and 16 from the removal of the infusion pump revealed a surprising lasting 'memory' of the exposure to GLP-1. Indeed, the best insulin secretory response was observed approximately 1 week after discontinuation of the GLP-1 infusion, and lasted up to 3 weeks from the early exposure to GLP-1. Detection of fasting plasma levels of GLP-1 during the 3 weeks of the experiment showed a very rapid decline, consistent with the data reported by others. Our findings provide evidence for a long-lasting beneficial effect of GLP-1 that persists for weeks even when the circulating levels of GLP-1 are back to normal.
Multiaxial mechanical behaviour of the passive ureteral wall: experimental study and mathematical characterisation

There is a scarcity of data regarding the mechanical properties of the ureter, although this would facilitate our understanding of its physiology and pathophysiology, and the development of suitable biomaterials for replacement. There is hence an urgent need for multiaxial experimental data and methodical constitutive formulations, which we aim at presenting through this report. The zero-stress state of wall tissue, serving as the starting geometry for biomechanical analyses, was accordingly determined and the 3D passive behaviour of ureteral specimens, isolated from healthy rabbits, was studied under a physiologic range of finite inflation and longitudinal extension. Two most-commonly employed descriptors of soft tissue behaviour were chosen to fit the material response: the Fung-type strain–energy function (SEF) and its combination with a quadratic function. Both SEFs were tested in the thick-walled setting, with incompressibility enforced explicitly or via a Lagrange multiplier. The deformational response of the ureter exhibited an exponential and not the sigmoidal dependency on pressure that requests implementation of two-term SEFs. Indeed, the four-parameter Fung-type SEF resulted in reasonable fit of both the external radius and longitudinal force vs. lumen pressure data, and fitting accuracy was not improved when attempting the seven-parameter Fung-type or biphasic SEFs. There were also serious over-parameterisation problems with those models, favouring the implementation of the SEF with the smallest number of parameters. The material parameters optimised revealed significant mechanical anisotropy, with longitudinal properties being stiffer than circumferential ones under equibiaxial stress states. We conclude that ureter displays a nonlinear anisotropic mechanical response that is well-characterised by the four-parameter Fung-type SEF.
Experimental Testing of a Method for On-Line Identification of the Cerebrospinal Fluid System

Accurate estimates of the compliance and outflow resistance of the human cerebrospinal fluid system are important for diagnosis of a medical condition known as hydrocephalus. In this paper we present a system which provides simultaneous on-line estimates of the outflow resistance and compliance. It's performance is experimentally verified using the same apparatus used to perform actual patient diagnoses and a specially designed physical model of the human cerebrospinal fluid system.
Urban Heat Island

We are all familiar with the fact that cities are generally warmer than the surrounding, more rural areas. We see it referenced most nights in our television weather reports. It is especially significant on nights with clear skies and light winds which favor radiational cooling. This is most significant in the rural areas but in the city, the excess heat absorbed during the day and the local heat sources maintain higher nighttime readings. During the days or nights with strong winds and clouds the differences are minimized due to mixing and the advective cooling of the city by the winds.
Planning and fast re-planning of safe motions for humanoid robots: Application to a kicking motion

Optimal motions are usually used as joint reference trajectories for repetitive or complex motions. In the case of soccer robots, the kicking motion is usually a benchmark motion, computed off-line, without taking into account the current position of the robot or the direction of the goal. Moreover, robots must react quickly to any situation, even if not expected, and cannot spend time to generate a new optimal motion by the classical way. Therefore, we propose a new method for fast motion re-planning based on an off-line computation of a feasible sub-set of the motion parameters, using Interval Analysis.
Constraints on galaxy bias, matter density, and primordial non-Gaussianity from the PSCz galaxy redshift survey.

We compute the bispectrum for the IRAS PSCz catalog and find that the galaxy distribution displays the characteristic signature of gravity. Assuming Gaussian initial conditions, we obtain galaxy biasing parameters 1/b(1) = 1.20(+0.18)(-0.19) and b(2)/b(2)(1) = -0.42+/-0.19, with no sign of scale-dependent bias for k < or = 0.3h Mpc(-1). These results impose stringent constraints on non-Gaussian initial conditions. For dimensional scaling models with chi(2)(N) statistics, we find N > 49, which implies a constraint on primordial skewness B3 < 0.35.
Protein secondary structure detection based on unsupervised word segmentation

Unsupervised word segmentation methods were applied to predict protein secondary structures. Protein sequences, such as 'MTMDKSELVQKA', were used as input to these methods. Segmented 'protein word' sequences, such as 'MTM DKSE LVQKA', were then obtained. The protein sequence can also be 'divided' into segments, such as 'MTMD KSE LVQKA', according to its secondary structure. The boundaries of the 'protein words' produced by unsupervised segmentation show the accordance with the boundary of the secondary structure. This work may spark some more new ideas to develop novel protein structure prediction methods. Our experiment also suggests there may be much more protein sequences in current noncoding regions. For example, we infer 16% area of human genome could be regarded as coding regions.
Effect of Diclofenac with B Vitamins on the Treatment of Acute Pain Originated by Lower-Limb Fracture and Surgery

The aim of this study was to compare the efficacy of diclofenac, for the treatment of acute pain originated by lower-limb fracture and surgery, with that of diclofenac plus B vitamins. This was a single-center, prospective, randomized, and double-blinded clinical trial. Patients with lower-limb closed fractures rated their pain on a 10 cm visual analog scale (VAS). Patients were then randomized to receive diclofenac or diclofenac plus B vitamins (thiamine, pyridoxine, and cyanocobalamin) intramuscularly twice daily. Patient evaluations of pain intensity were recorded throughout two periods: twenty-four hours presurgery and twenty-four hours postsurgical. One hundred twenty-two patients completed the study. The subjects' assessments of limb pain on the VAS showed a significant reduction from baseline values regardless of the treatment group. Diclofenac plus B vitamins combination was more effective to reduce the pain than diclofenac alone. The results showed that the addition of B vitamins to diclofenac increased its analgesic effect. The novelty of this paper consists in that diclofenac and diclofenac plus B vitamins were useful for treatment of acute pain originated by lower-limb fracture and surgery.
A basic circuit for asynchronous superconductive logic using RSFQ gates

This paper presents a basic circuit concept for pulse-driven asynchronous circuits using superconducting rapid single-flux-quantum (RSFQ) logic gates. Today's computer systems perform using a synchronous clock distributed over the whole system. The distribution of the clock signal becomes more difficult as the clock frequency increases because the wavelength of the clock signal becomes shorter than the system size. One way to solve this problem is to use asynchronous circuits in which all circuits perform their functions only under the law of cause and effect. We propose an implementation of the basic asynchronous circuit performing OR/AND logic operations between SFQ pulses. The operations are confirmed by SPICE simulation. We will show a design method for combinational circuits using the proposed basic circuits.
Efficient parallel global garbage collection on massively parallel computers

On distributed-memory high-performance massively parallel computers (MPPs) where processors are interconnected by an asynchronous network, efficient garbage collection (GC) becomes difficult, due to inter-node references and references within pending, unprocessed messages. Our parallel global GC algorithm (1) takes advantage of reference locality, (2) efficiently traverses references over nodes, (3) admits a minimum pause time for the ongoing computations, and (4) has been shown to scale up to 1024-node MPPs. The algorithm employs a global weight counting scheme to substantially reduce message traffic. Two methods for confirming the arrival of pending messages are used: one counts the number of messages and the other uses network 'bulldozing'. Performance evaluations in actual implementations on a multicomputer with from 32 to 1024 nodes, the Fujitsu AP1000, reveals various favorable properties of the algorithm. <<ETX>>
A SURVEY OF ORAL AND MAXILLOFACIAL BIOPSIES IN CHILDREN. A SINGLE-CENTER RETROSPECTIVE STUDY OF 20 YEARS IN PELOTAS-BRAZIL

Despite the large number of published cases about oral and maxillofacial pediatric lesions, the literature is scarce on epidemiological studies regarding the prevalence of these entities. This study retrieved oral and maxillofacial pediatric lesions from the Center of Diagnosis of Oral Diseases (CDDB) at the Dental School of the Federal University of Pelotas (UFPEL), comprising a 20-year period (1983-2002). From the total of 9,465 biopsies received in this period, 625 (6.6%) were from children aged 0 to 14 years. Regardless of the histopathological diagnosis, patient data referring to lesion location, sex and age were collected. Diagnoses were grouped in 13 categories. As much as 89% of the cases occurred in patients aged 7 to 14 years (53% in females and 47% in males). Mucocele (17.2%) was the most common type of lesion, followed by dentigerous cyst (8.6%). In the category of odontogenic tumors, odontoma was the most frequent lesion (64.2%). Malignant lesions were observed in a small section of the sample (1.2%). Generally, the results of the present study are in line with those reported in the literature concerning the most prevalent lesions in the pediatric population. Most lesions were benign, and malignant lesions were diagnosed in a very small part of the sample.
Partial Evaluation for Higher-Order Languages with State

We have designed and implemented an o(cid:15)ine partial evaluator for a higher-order language with (cid:12)rst-class references. Its distinguishing feature over other partial evaluators is its ability to perform assignments to local and global references at specialization time for a higher-order language. The partial evaluator consists of a region-based monovariant binding-time analysis and a specializer in essentially continuation-passing store-passing style, thus generalizing type-based binding-time analysis and continuation-based partial evaluation. The partial evaluator yields good results for realistic problems such as object-oriented programming, uni(cid:12)cation
Activity-Dependent and Activity-Independent Development of the Axon Initial Segment

The axon initial segment (AIS) is the site of spike initiation in neurons. Previous studies revealed that spatial distribution of the AIS varies greatly among neurons to meet their specific needs. However, when and how this differentiation arises is unknown. Neurons in the avian nucleus laminaris (NL) are binaural coincidence detectors for sound localization and show differentiation in the distribution of the AIS, with shorter length and a more distal position from the soma with an increase in tuning frequency. We studied these characteristics of the AIS in NL neurons of the chicken during development and found that the AIS differentiates in its distribution after initial formation, and this is driven by activity-dependent and activity-independent mechanisms that differentially regulate distal and proximal boundaries of the AIS. Before hearing onset, the ankyrinG-positive AIS existed at a wide stretch of proximal axon regardless of tuning frequency, but Na+ channels were only partially distributed within the AIS. Shortly after hearing onset, Na+ channels accumulated along the entire AIS, which started shortening and relocating distally to a larger extent in neurons with higher tuning frequencies. Ablation of inner ears abolished the shortening of the AIS without affecting the position of its proximal boundary, indicating that both distal and proximal AIS boundaries are disassembled during development, and the former is dependent on afferent activity. Thus, interaction of these activity-dependent and activity-independent mechanisms determines the cell-specific distribution of the AIS in NL neurons and plays a critical role in establishing the function of sound localization circuit.
Effects of Decomposition on Gunshot Wound Characteristics: Under Moderate Temperatures with Insect Activity

Abstract: Previous studies document characteristics of gunshot wounds shortly after they were inflicted. This study was conducted to determine if the early stages of decomposition obscure or alter the physical surface characteristics of gunshot wounds, thereby affecting the quantity and quality of information retrievable from such evidence. The study was conducted in August and September, 2005 in Nova Scotia, Canada in forested and exposed environments. Recently killed pigs were used as research models and were shot six times each at three different ranges (contact, 2.5 cm, and 1.5 m). Under these test conditions, the gunshot wounds maintained the characteristics unique to each gunshot range and changes that occurred during decomposition were not critical to the interpretation of the evidence. It was concluded that changes due to decomposition under the conditions tested would not affect the collection and interpretation of gunshot wound evidence until the skin was degraded in the late active or advanced decay stage of decomposition.
Frequency splitting patterns in wireless power relay transfer

Frequency splitting patterns in low-order wireless power relay transfer systems are analysed by the coupled-mode theory. In addition to the V-type splitting pattern reported widely, two new patterns, I-type and W-type, are introduced. Specifically, it is found that a 0-relay system shows a V-type or I-type splitting; a symmetrical 1-relay system shows an I-type or W-type splitting; and a symmetrical 2-relay system usually shows a V-type or W-type splitting. The criteria for different frequency splitting patterns are given, and the theoretical results are validated finally by 1-relay and 2-relay wireless power transfer experimental systems.
The Interaction Between Head-Tracker Latency, Source Duration, and Response Time in the Localization of Virtual Sound Sources

One of the fundamental limitations on the fidelity of interactive virtual audio display systems is the delay that occurs between the time a listener changes his or her head position and the the time the display changes its audio output to reflect the corresponding change in the relative location of the sound source. In this experiment, we examined the impact that six difference headtracker latency values (12, 20, 38, 73, 145 and 243 ms) had on the localization of broadband sound sources in the horizontal plane. In the first part of the experiment, listeners were allowed to take all the time they needed to point their heads in the direction of a continuous sound source and press a response switch. In the second part of the experiment, the stimuli were gated to one of eight different durations (64, 125, 250, 375, 500, 750, 1000 and 2000 ms) and the listeners were required to make their head-pointing responses within two seconds after the onset of the stimulus. In the openended response condition, the results showed that latencies as long as 243 ms had no impact on localization accuracy, but that there was an increase in response time when then latency was longer than 73 ms. In contrast, the data from the time-limited response conditions showed that latencies that exceeded 73 ms had no impact on response time but that they significantly increased the angular localization error and the number of front back confusions. Together with the results of earlier studies, these results suggest that headtracker latency values of less than 70 ms are adequate to obtain acceptable levels of localization accuracy in virtual audio displays.
Estimation of Word Net-Based Lexical Semantic Similarity Measure for Telugu Documents

The estimation of lexical semantic relatedness has numerous applications in NLP. Several measures are available for the evaluation of lexical semantic relatedness. This paper presents two approaches for measuring semantic similarity/distance between words and concepts with the help of WordNet-Telugu. The edge-based approach of the edge counting scheme and the node-based approach of the information content calculation have been explored. In the field of concepts, the measure of Wu and Palmer has the advantage of being simple to implement and have good performances compared to the other similarity measures. The obtained results show that the Wu and Palmer approach presents a better performance in terms of relevance.
In vivo characterization of a versatile 8-channel digital biopotential recording system with sub-μVRMS input noise

This work presents the design and testing of an integrated 8-channel CMOS biopotential recording chip, consisting of low-noise input stages, tunable second stage, a multiplexer, and two analog-to-digital converters (ADC). Through its variable supply concept, the integrated input-referred noise of the first stage is selectable from 1.5 down to 0.63 μVRMS (ISS = 200 μA), which is superior to standard laboratory recording systems. The device features variable lower and upper corner frequencies, and outputs two digital 16-bit data streams at 62.5 kS/s. The chip die was fabricated in X-Fab 0.35 μm CMOS technology and has an area of 10 mm2.
