A simple through-only de-embedding method for on-wafer S-parameter measurements up to 110 GHz

The present paper proposes the simple deembedding method for 110-GHz on-wafer S-parameter measurements. While conventional de-embedding methods require two or more dummy patterns, our method only uses a through pattern and can perform accurate de-embedding up to 110 GHz. Differences among the proposed method and previous through-only de-embedding methods are that our method is available for various device under tests and higher frequencies.
Multi-Aspect Feature Based Neural Network Model in Detecting Fake Reviews

With the development of network technology and e-commerce, online-purchasing has become a fashion which takes a significant ratio of the whole market. Product reviews in e-market platform have a lot of information, and buyers tend to rely on the product'information and the reviews to determine the exactly quality of the product. However, the existence of fake reviews will mislead the consumers and result in property losses and unsatisfactory transaction experience, and even the failure of the e-market platform in the long run. Therefore, it is significant to detect the fake reviews effectively. In this paper we propose a multi-aspect based neural network model to identify fake reviews, where the review features in the three aspects: metadata, similarity, and sentiment, are considered. We further establish the supervisory model and use the neural network training classifier to identify the fake reviews. Our experimental results show that this method has a great recognition rate and recall rate.
THE EFFECTS OF CORTISONE AND ADRENOCORTICOTROPHIC HORMONE ON POLIOMYELITIS AND ON OTHER VIRUS INFECTIONS

Number of mice THERE is growing evidence that under certain circumstances cortisone reduces the resistance of animals to bacterial infections ; thus the infection becomes more intense after cortisone in experimental tuberculosis, syphilis, and pneumococcal septicaemia. There is also evidence that cortisone has a similar action in some virus infections. Schwartzmannl found that cortisone had an accelerating action on poliomyelitis in mice when the virus was inoculated intracerebrally. In addition, golden hamsters, Mesocricetus auratus, which normally are highly resistant to intracerebral inoculation with Lansing types of poliomyelitis virus, were found to become highly susceptible to this route of infection when MEFl poliomyelitis virus was injected intracerebrally.
Visualizations for Software Development Process Management

Software development projects have increasingly been adopting new practices, such as continuous delivery and deployment to enable rapid delivery of new features to end users. Tools that are commonly utilized with these practices generate a vast amount of data concerning various development events. Analysis of the data provides a lightweight data driven view on the software process. We present an efficient way of visualizing software process data to provide a good overall view on the features and potential problems of the process. We use the visualization in a case project that has become more agile by applying continuous integration and delivery together with development and infrastructure automation. We compare data visualizations with information gathered from the development team and describe how the evolution can be understood through our visualizations. The case project is a good example of how a change from a traditional long cycle development to a rapid cycle DevOps culture can actually be made in a few years. However, the results show that the team has to focus on the process improvement continuously in order to maintain continuous delivery all the time. As the main contribution, we present a lightweight way to software process visualization. Moreover, we discuss how such a heuristic can be used to track the characteristics of the target process.
Observation of gate-tunable coherent perfect absorption of terahertz radiation in graphene

We report experimental observation of electrically-tunable coherent perfect absorption (CPA) of terahertz (THz) radiation in graphene. We develop a reflection-type tunable THz cavity formed by a large-area graphene layer, a metallic reflective electrode and an electrolytic medium in between. Ionic gating in the THz cavity allows us to tune the Fermi energy of graphene up to 1eV and to achieve critical coupling condition at 2.8 THz with absorption of 99%. With the enhanced THz absorption, we were able to measure the Fermi energy dependence of the transport scattering time of highly doped graphene. Furthermore, we demonstrate flexible active THz surfaces that yield large modulation in the THz reflectivity with low insertion losses. We anticipate that the gate-tunable CPA will lead efficient active THz optoelectronics applications.
MRI extrahippocampal volumes and visual memory: Correlations independent of MRI hippocampal volumes in temporal lobe epilepsy patients

Limbic system atrophy and memory dysfunction are common in patients with temporal lobe epilepsy (TLE). However, the relationship between extrahippocampal limbic structures and memory functioning within TLE has received little attention. The present study examined associations of MRI volumetric measurements of the mammillary body, fornix, amygdala, and hippocampus to measures of episodic verbal and visual memory. The Logical Memory and Visual Reproduction subtests from the Wechsler Memory Scale were administered to 47 unilateral TLE patients (25 right, 22 left). Normalized right and left MRI volumes were determined for each patient by cursor tracing 1.5 mm slices from 3D-MRI. Significant associations were found between left hippocampal volume and the immediate, delayed, and percent retention scores of the Logical Memory Test; between the left mammillary body volume and the Logical Memory Test delayed and percent retention scores; immediate Visual Reproduction performance was significantly related to the right and left amygdala volumes, and right mammillary body volume; only the right amygdala and right mammillary body volume were associated with the delayed Visual Reproduction trial. However, neither right nor left hippocampal volumes were related to visual memory performance. Multiple limbic system structural volumes were independently associated with verbal and nonverbal memory performance. Results suggest that visual memory, as measured by the Visual Reproduction Test, may be uniquely associated with extrahippocampal volumes in patients with TLE. (JINS, 1999, 5, 540–548.)
Shp-2 tyrosine phosphatase: signaling one cell or many.

Shp-2, a widely expressed cytoplasmic tyrosine phosphatase with two src-homology 2 (SH2) domains, has received much attention in the signal transduction field recently. Significant progress has been made in understanding the structure and function of this phosphatase, together with its Drosophila homologue, Corkscrew, as well as the close relative Shp-1 tyrosine phosphatase. The crystal structure of Shp-2 revealed an autoinhibitory mechanism of the catalytic activity by the N-terminal SH2 domain. Shp-2 apparently participates in signaling events downstream of receptors for growth factors, cytokines, hormones, antigens, and extracellular matrixes in the control of cell growth, differentiation, migration, and death. Shp-2 is an important molecule that integrates signals among various cytoplasmic pathways and may also couple intracellular and intercellular information flow.
Temperature Acclimation: Influence on Transient Outward and Inward Currents in an Identified Neurone of Helix Pomatia

1. To gain insight into the mechanisms underlying compensatory changes in excitability induced by thermal acclimation we examined the effects of short-term and long-term temperature transition on a transient outward potassium current (A-current) and the transient inward current in an identified neurone (Br) of the land snail Helix pomatia . 2. The A-current in neurones from snails acclimated to 20°C was suppressed by cooling to 3°C, with a Q 10 of 4.5 between 10°C and 20°C. This is consistent with suppression of the ability of these neurones to fire repetitively at low temperatures. 3. Neurones acclimated to low temperature (5°C) partially recovered their ability to fire repetitively, but exhibited no A-current, at this temperature. 4. Neither the equilibrium potential for the A-current (E A ), the steady-state inactivation parameters of the A-current (B o ), nor the ratio of the time constants of A-current activation and inactivation (τA/τB) were affected by cooling, leading to the conclusion that the reduction of the A-current by cooling was due to a decrease in the A-current activation parameters (G A A∞). 5. Cooling reduced the maximum peak inward current, with a Q 10 of 2, in neurones from warm-acclimated animals. After acclimation to 5°C, maximum peak inward current partially recovered. 6. Cooling neurones from warm-acclimated animals slowed the time course of the recovery of inward current from inactivation. Acclimation to the cold caused a partial, compensatory shortening of the inactivation removal process.
Why do Clawback Provisions Affect Financial Reporting Quality ?-An Analysis of Trigger Effects

We identify clawback triggers from firms’ proxy statements (Form DEF 14A) and use the likelihood of restatements to proxy for financial reporting quality. Based on a sample of 578 U.S. firms that voluntarily adopt clawback provisions during 2003-2009, when restatement-based triggers could be decomposed into two types: fraud and unintentional error, and we do observe the evidence that using fraud triggers is associated with high financial reporting quality. The findings support that fraud triggers can enhance deterrent effect of clawback provision by establishing a viable disincentive against fraud, misconduct, and otherwise harmful acts. These results are robust to controlling for the compensation components, to different sample specifications and to a number of sensitivity.

Trypanosoma brucei: constitutive activity of the VSG and procyclin gene promoters.

The variant surface glycoprotein (VSG) and procyclin are the major surface proteins of the bloodstream and procyclic stages, respectively, of Trypanosoma brucei. The promoter regions of the VSG and procyclin gene transcription units could be mapped thanks to the specific enrichment of initial transcripts that occurs following UV irradiation. Whereas the VSG gene is 45 kb distant from its promoter, procyclin genes are located immediately downstream. We show, by run‐on assays on isolated nuclei and by cDNA analysis, that transcription occurs from both promoters in bloodstream as well as in procyclic forms. It is inferred that the control of the stage‐specific expression of VSG and procyclin genes is not effected at the level of transcription initiation, but most probably by interfering with the elongation and stability of the specific transcripts.
Isolated Mandarin base-syllable recognition based upon the segmental probability model

A segmental probability model (SPM) is proposed for fast and accurate recognition of the highly confusing isolated Mandarin base-syllables by deleting the state transition probabilities of continuous density hidden Markov models (CHMM), abandoning the dynamic programming process, letting the states equally segment the base-syllables deterministically, and using several special approaches to improve the accuracy and speed. This is achieved by considering the special characteristics of the target vocabulary.
Ultra-Low-Voltage 20-GHz Frequency Dividers Using Transformer Feedback in 0.18-$\mu$ m CMOS Process

This paper presents the design and analysis of ultra- low-voltage (ULV) high-frequency dividers using transformer feedback. Specifically, a differential-input differential-output injection-locked (IL) divider topology with transformer feedback and a wideband transformer-coupled (TC) divider with quadrature outputs are demonstrated, both of which can operate well at supply voltages as low as the device's threshold voltages. Fabricated in a standard 0.18-mum CMOS process, the ULV-IL divider measures an input frequency range from 16.1 GHz to 20 GHz while consuming a total power from 2.75 mW to 4.35 mW at 0.5 V supply, and the TC-divider measures an input frequency range of 27.8% from 15.1 GHz to 20 GHz with IQ sideband rejection of - 31&nbsp;dBc while consuming power from 11.4 mW to 13.6 mW at 0.6 V supply.
Interference between concurrent tasks of driving and telephoning.

224 men were given the task of judging whether to drive through gaps which might be larger or smaller than the car, and a telephoning task of checking the accuracy of short sentences. Interference between the concurrently performed tasks was investigated. Telephoning mainly impaired judgments of "impossible" gaps. The control skills employed in steering through "possible" gaps were not reliably degraded, although speed of driving was reduced. Driving increased errors and prolonged RTs on the sentence-checking task. It is concluded that telephoning has a minimal effect on the more automatized driving skills, but that perception and decision-making may be critically impaired by switching between visual and auditory inputs.

Point pattern matching in the analysis of two‐dimensional gel electropherograms

In the automation of proteome analysis, matching of two‐dimensional (2‐D) electropherograms represents a bottleneck in the process. Here we present a point pattern recognition approach to the matching of spots in 2‐D electropherograms. The algorithm is based on a comparison of spot neighborhoods, converted to point patterns between reference and compared gels. The neighborhood was characterized by a syntactic descriptor which minimized the influence of spot displacements. A combined criterion utilizing the similarity of point patterns and a metric definition of position similarity was derived. The efficiency and accuracy of the algorithm was tested on a set of 69 gels with different levels of similarity. For a typical gel the accuracy of matching was higher than 98% and the number of correctly identified spots was higher than 95%.
The effect of surgical trauma on rat tunica albuginea.

PURPOSE Increased TGF-beta1 protein expression in tunica albuginea has been found to be associated with Peyronie's disease. The present study is designed to investigate whether surgical trauma induces TGF-beta up-regulation and histological changes in rat penis. MATERIALS AND METHODS Thirty-two adult male Sprague-Dawley rats were divided into two groups. The first group (n=24) underwent incision and suture repair of the tunica albuginea of the penis. The second group (n=8) received sham surgery (incision of the penile skin and underlying fascia) as the control group. The trauma-induced group was divided into four subgroups in which the rats were euthanized at 6 hours (n=6), 1 day (n=6), 3 days (n=6), and 8 weeks (n=6). Two sham-operated (control) animals were also euthanized at each of the above time points. All tunical tissues from the trauma-induced and sham-operated rats were collected and examined histologically using Trichrome and Hart elastic fiber stain. Electron microscopy was used to study the ultrastructural changes of both trauma induced and control specimens. Western blotting technique was performed to study TGF-beta protein expression in both experimental and sham-operated groups. RESULTS Tissue edema and hemorrhage between collagen bundles are noted in the experimental groups after 6 hours, 1 day and 3 days. At 8 weeks the most prominent changes observed were inflammatory cellular infiltration and disorganization of the collagen bundles. In the control group the tunica albuginea retains normal wavy regular appearance in all rats. This histological analysis is similar to the reported description of histological features of the acute phase of Peyronie's disease. Electron microscopy showed packed collagen bundles in the trauma-induced group with normal appearing elastic fibers. No abnormal change was detected in the control group. Immunoblot results revealed remarkable TGF-beta1 protein expression in 1, 5, 3, and 0 rats of trauma induced subgroups after 6 hours, 1 day, 3 days, and 8 weeks respectively. No TGF-beta1 protein expression in any rats in the control group was detected. No significant TGF-beta2 or TGF-beta3 protein expression was observed either in the trauma induced group or in the control group. CONCLUSION Trauma can induce histological changes similar to the acute phase of Peyronie's disease but not the overt picture of the chronic phase of Peyronie's disease. It can also result in an early but transient up-regulation of TGF-beta1 protein expression in the rat penis. We conclude that surgical incisional trauma does not result in Peyronie's disease-like changes in the tunica.
FPGA Implementation of Computer Vision Algorithm

Computer vision algorithms, which play an significant role in vision processing, is widely applied in many aspects such as geology survey, traffic management and medical care, etc. Most of the situations require the process to be real-timed, in other words, as fast as possible. Field Programmable Gate Arrays (FPGAs) have a advantage of parallelism fabric in programming, comparing to the serial communications of CPUs, which makes FPGA a perfect platform for implementing vision algorithms. These algorithms usually have a very high computation power because the objects, a large amount of pixels of a single picture, have to be proceeded not once, but many times. This project reconfigured onto the FPGA board, Terasic DE2i-150, a partial of a algorithm that has multiplexing computations. The algorithm of Harris corner detection is chosen, which contains an important step in many vision processing and is of good performance. The reconfiguration of the most time-consuming portion has synthesized onto the board and a result is presented to demonstrate the performance and the capacity of the FPGA. It shows that even a low-cost FPGA in 50MHz can achieve a faster speed than that of some CPUs due to the parallelism, which is the specialization of FPGAs and is unfeasible to apply to software.
Contribution of a color space selection to a flaw detection vision system

Abstract. We present a line scan color vision system that detects aspect flaws occurring on the color surfaces of drinking glasses decorated due to an industrial silk-screen process. For this purpose, we have designed a specific image acquisition device based on a color line-scan camera. As the pattern printed on glasses slightly varies between two glasses successively produced, flaw detection by color image analysis is a challenging problem. In order to overcome this problem, the aspect flaws detection is based on an original color image segmentation scheme that iteratively constructs pixel classes. Since the results of segmentation scheme are known to depend on the choice of the color space, the main originality of our approach is to automatically determine the most discriminant color space for each class to be constructed. Experimental results show that the selection of the well-suited color spaces contributes to improve the segmentation accuracy and the aspect flaw detection.
Value of Pre‐Hospital Discharge Defibrillation Testing in Recipients of Implanted Cardioverter Defibrillators

Opinions vary regarding the need to perform defibrillation testing prior to hospital discharge in recipients of state‐of‐the‐art cardioverter defibrillators (ICDs). Our protocol is to perform predischarge ICD testing 1 day after implant. This report includes 682 consecutive implants. Adverse observations at testing were grouped into (1) risk of defibrillation failure, (2) surgical complications, (3) sensing/pacing issues or narrow defibrillation margin warranting closer follow‐up, or (4) findings correctable by device reprogramming. Among the 682 patients, 63% had single‐chamber and 37% dual‐chamber or biventricular ICDs. In 48 patients (7%) there were 69 concerns and/or interventions, with overlaps among the four categories, including one failure to defibrillate (0.15%), and six other patients at risk. Surgical complications included 11 hematomas (1.6%), and six lead dysfunctions. Closer follow‐up was indicated in 19 patients (2.7%), for high pacing thresholds in seven, sensing issues in seven, and <10 J defibrillation margin in five. Device reprogramming was needed in 31 patients (4.5%), for tachycardia detection and therapy settings in 12, and for pacing/sensing functions in 22 patients. In eight patients ventricular fibrillation could not be induced. There was no morbidity or mortality due to testing. The state‐of‐the‐art ICDs delivering biphasic shocks are remarkably reliable. The routine pre‐hospital discharge defibrillation testing of such ICDs may be optional and left to the physicians’ discretion.
Ankle Trauma Significantly Impairs Posture Control -A Study in Basketball Players and Controls

Both ankle and hip movements are used to maintain balance in strategies defined as bottom up and top down models. This suggests that pathological impairment of either of these articulations could modify the parameters of balance control. In order to appreciate the bearing of ankle damage on the proper control of equilibrium, posturographic recordings were compared, in a static and two dynamic tests, between 15 professional national basketball players, with histories of 10 to 15 ankle sprains, and 50 controls. In statokinesigrams obtained with eyes open or closed, center of foot pressure displacements were of similar length (way) between controls and players, while the area covered was increased for the latter and related to the history of ankle trauma. In a toes-up dynamic test (4 degrees, 50 degrees/s) coupled with electromyographic recordings, the short latency response (myotatic reflex in the triceps surae muscle) normalized to one meter body height, was shorter in players without relationship to histories of ankle damage. In a prolonged sinusoidal dynamic test, players with the largest number of ankle trauma showed greater difficulties in maintaining posture control. These data pinpoint the role of ankles in the control of both static and dynamic balance and demonstrate that the role of the hip joints becomes more important (top down strategy) in the case of damaged ankles.
