Variations on Minimal Gauge Mediated Supersymmetry Breaking

We study various modifications to the minimal models of gauge-mediated supersymmetry breaking. We argue that, under reasonable assumptions, the structure of the messenger sector is rather restricted. We investigate the effects of possible mixing between messenger and ordinary squark and slepton fields and, in particular, violation of universality. We show that acceptable values for the {mu} and B parameters can naturally arise from discrete, possibly horizontal, symmetries. We claim that in models where the supersymmetry-breaking parameters A and B vanish at the tree level, tan{beta} could be large without fine-tuning. We explain how the supersymmetric CP problem is solved in such models. {copyright} {ital 1997} {ital The American Physical Society}
Code excited linear prediction codec for electrocardiogram

In This work we propose a CELP ECG codec for medical telemetry. The encoding algorithm is based on code-excited linear prediction (CELP). The general framework proposed is: QRS detection, calculation of LPC parameter, generation of residual error signal, codebook generation, MSE (mean square error) search. The codebook is generated for residual error. The indices of the codebook and corresponding LPC parameters are transmitted where the minimum MSE occurs. A replica of the transmitter codebook is present at the receiver. Corresponding to the received index value residual error coefficients are retrieved from the receiver codebook. The ECG signal is reconstructed from the retrieved code word.
Mechanisms and Management of Diabetic Painful Distal Symmetrical Polyneuropathy

Although a number of the diabetic neuropathies may result in painful symptomatology, this review focuses on the most common: chronic sensorimotor distal symmetrical polyneuropathy (DSPN). It is estimated that 15–20% of diabetic patients may have painful DSPN, but not all of these will require therapy. In practice, the diagnosis of DSPN is a clinical one, whereas for longitudinal studies and clinical trials, quantitative sensory testing and electrophysiological assessment are usually necessary. A number of simple numeric rating scales are available to assess the frequency and severity of neuropathic pain. Although the exact pathophysiological processes that result in diabetic neuropathic pain remain enigmatic, both peripheral and central mechanisms have been implicated, and extend from altered channel function in peripheral nerve through enhanced spinal processing and changes in many higher centers. A number of pharmacological agents have proven efficacy in painful DSPN, but all are prone to side effects, and none impact the underlying pathophysiological abnormalities because they are only symptomatic therapy. The two first-line therapies approved by regulatory authorities for painful neuropathy are duloxetine and pregabalin. α-Lipoic acid, an antioxidant and pathogenic therapy, has evidence of efficacy but is not licensed in the U.S. and several European countries. All patients with DSPN are at increased risk of foot ulceration and require foot care, education, and if possible, regular podiatry assessment.
Path Curvature Discrimination: Dependence on Gaze Direction and Optical Flow Speed

Many experimental approaches to the control of steering rely on the tangent point (TP) as major source of information. The TP is a good candidate to control self-motion. It corresponds to a singular and salient point in the subject's visual field, and its location depends on the road geometry, the direction of self-motion relative to the road and the position of the driver on the road. However, the particular status of the TP in the optical flow, as a local minimum of flow speed, has often been left aside. We therefore assume that the TP is actually an optimal location in the dynamic optical array to perceive a change in the trajectory curvature. In this study, we evaluated the ability of human observers to detect variations in their path curvature from optical flow patterns, as a function of their gaze direction in a virtual environment. We simulated curvilinear self-motion parallel to a ground plane. Using random-dot optic flow stimuli of brief duration and a two-alternative forced-choice adaptive procedure, we determined path curvature discrimination thresholds, as a function of gaze direction. The discrimination thresholds are minimal for a gaze directed toward a local minimum of optical flow speed. A model based on Weber fraction of the foveal velocities () correctly predicts the relationship between experimental thresholds and local flow velocities. This model was also tested for an optical flow computation integrating larger circular areas in central vision. Averaging the flow over five degrees leads to an even better fit of the model to experimental thresholds. We also found that the minimal optical flow speed direction corresponds to a maximal sensitivity of the visual system, as predicted by our model. The spontaneous gazing strategies observed during driving might thus correspond to an optimal selection of relevant information in the optical flow field.
The Perception of Creaminess in Sour Cream

Creaminess is a consumer attribute that is frequently used to describe sour cream; however, creaminess is difficult to define or describe and is poorly understood because the mechanism or modality(s) for its perception remain uncertain. The objective of this study was to determine what sensory modality, or combination thereof, was responsible for the perception of creaminess in sour cream. Consumers (n = 274 baseline control, n = 100 each modality study) evaluated creaminess and overall liking of 12 samples representing the sensory space of commercial sour creams. Subsequently, in separate sessions, the effect of each sensory modality was evaluated: visual only, stirring, blindfolded stirring, blindfolded tasting, blindfolded tasting with nose clips and tasting with nose clips. An 11-point creaminess rating scale was used to evaluate creaminess perception, and overall liking was evaluated using the 9-point hedonic scale. The effect of session type (modality), panelist and fat content on creaminess and overall liking was evaluated using a mixed-model analysis of variance. Flavor had the greatest impact on creaminess perception (P < 0.05) followed by visual assessment of sour cream while stirring. Creaminess perception of sour cream is assessed by an olfaction-related mechanism and also by flow characteristics while stirring. Practical Applications In the wake of the health and wellness trend as well as the adult and childhood obesity epidemic, low-fat and fat-free dairy products are poised to fill a healthy diet niche. These products have historically performed poorly in comparison with their full-fat counterparts. Creaminess is associated with dairy product liking. It is also an attribute that is difficult to measure due to the complexity of how it is perceived by consumers. This study established that flavor is the most important sensing modality when assessing the creaminess of sour cream orally, but that textural components also exist.

Approximation and small depth Frege proofs

M. Ajtai (1988) recently proved that if, for some fixed d, every formula in a Frege proof of the propositional pigeonhole principle PHP/sub n/ has depth at most d, then the proof size is not less than any polynomial in n. By introducing the notion of an approximate proof the authors demonstrate how to eliminate the nonstandard model theory, including the nonconstructive use of the compactness theorem, from Ajtai's lower bound. An approximate proof is one in which each inference is sound on a subset of the possible truth assignments-possibly a different subset for each inference. The authors also improve the lower bound, giving a specific superpolynomial function bounding the proof size from below. <<ETX>>

Cadmium affects microtubule organization and post-translational modifications of tubulin in seedlings of soybean (Glycine max L.)

Cadmium (Cd) is a non-essential heavy metal, toxic to all living organisms. The microtubule (MT) cytoskeleton appears to be one of the main targets of Cd action. In this study we present, with the use of various immunological approaches, the effect of Cd at moderate (85 μM) and high (170 μM) concentrations on the structure and functioning of the MT cytoskeleton in the root cells of soybean seedlings. As the result of heavy metal action, root growth was significantly diminished and was accompanied by a reduction in mitotic activity and disturbance in the structure of the MT arrays, including randomization of the cortical MT arrangement, distorted mitotic arrays and complete depolymerization of the MTs. Biochemical analysis revealed decreased levels of various α- and β-tubulin isoforms with a parallel down-regulation of most examined α-tubulin genes. Simultaneously, Cd treatment led to differentiated changes in the level of tubulin post-translational modifications, including tyrosination, detyrosination, acetylation, and polyglutamylation. Decreased tyrosination and polyglutamylation of particular tubulin isoforms accompanied by increase in the level of specific detyrosinated and acetylated isoforms implies augmented stability and reduced turnover of the MTs during stress conditions. Taken together, the obtained results indicate the significant impact of Cd on gene expression levels and subsequent post-translational processing of tubulin, which may be related to the impairment of MT cytoskeleton functioning in root cells.
QoS control to handle long-duration large flows and its performance evaluation

A method of controlling the rate of long-duration large flows and its performance evaluation is described in this paper. Most conventional QoS controls allocate a fair-share bandwidth to each flow regardless of its duration. Thus, a long-duration large flow (such as a P2P flow) is allocated the same bandwidth as a short-duration flow (such as data from a Web page) in which the user is more sensitive to response time. As a result, long-duration flows will occupy the bandwidth over the long period and worsen response times of short-duration flows, and the conventional QoS methods do nothing to prevent this. We have, therefore, proposed a new form of QoS control that takes flow duration into account and assigns higher priority to the acceptance of shorter-duration flows. In this paper, we show through simulation that our method achieves high performance for short-duration flows without degrading the performance of long-duration flows. We also explain how to set parameters used in our method. Furthermore, we discuss the applicability of a packet-sampling technique to improve the method's scalability.

Optimal Reconstruction with a Small Number of Views

Estimating positions of world points from features observed in images is a key problem in 3D reconstruction, image mosaicking, simultaneous localization and mapping and structure from motion. We consider a special instance in which there is a dominant ground plane $\mathcal{G}$ viewed from a parallel viewing plane $\mathcal{S}$ above it. Such instances commonly arise, for example, in aerial photography. Consider a world point $g \in \mathcal{G}$ and its worst case reconstruction uncertainty $\varepsilon(g,\mathcal{S})$ obtained by merging \emph{all} possible views of $g$ chosen from $\mathcal{S}$. We first show that one can pick two views $s_p$ and $s_q$ such that the uncertainty $\varepsilon(g,\{s_p,s_q\})$ obtained using only these two views is almost as good as (i.e. within a small constant factor of) $\varepsilon(g,\mathcal{S})$. Next, we extend the result to the entire ground plane $\mathcal{G}$ and show that one can pick a small subset of $\mathcal{S'} \subseteq \mathcal{S}$ (which grows only linearly with the area of $\mathcal{G}$) and still obtain a constant factor approximation, for every point $g \in \mathcal{G}$, to the minimum worst case estimate obtained by merging all views in $\mathcal{S}$. Our results provide a view selection mechanism with provable performance guarantees which can drastically increase the speed of scene reconstruction algorithms. In addition to theoretical results, we demonstrate their effectiveness in an application where aerial imagery is used for monitoring farms and orchards.
Conservation of allelic richness in wild crop relatives is aided by assessment of genetic markers.

Wild crop relatives are an important source of genetic variation for improving domesticated species. Given limited resources, methods for maximizing the genetic diversity of collections of wild relatives are needed to help spread protection over a larger number of populations and species. Simulations were conducted to investigate the optimal strategy of sampling materials from populations of wild relatives, with the objective of maximizing the number of alleles (allelic richness) in collections of fixed size. Two methods, based on assessing populations for variation at marker loci (e.g., allozymes, restriction fragment length polymorphisms), were developed and compared with several methods that are not dependent on markers. Marker-assisted methods yielded higher overall allelic richness in the simulated collections, and they were particularly effective in conserving geographically localized alleles, the class of alleles that is most subject to loss.
Interpreting traffic dynamics using ubiquitous urban data

Given a large collection of urban datasets, how can we find their hidden correlations? For example, New York City (NYC) provides open access to taxi data from year 2012 to 2015 with about half million taxi trips generated per day. In the meantime, we have a rich set of urban data in NYC including points-of-interest (POIs), geo-tagged tweets, weather, vehicle collisions, etc. Is it possible that these ubiquitous datasets can be used to explain the city traffic? Understanding the hidden correlation between external data and traffic data would allow us to answer many important questions in urban computing such as: If we observe a high traffic volume at Madison Square Garden (MSG) in NYC, is it because of the regular peak hour or a big event being held at MSG? If a disaster weather such as a hurricane or a snow storm hits the city, how would the traffic be affected? Most of existing studies on traffic dynamics focus only on traffic data itself and do not seek for external datasets to explain traffic. In this paper, we present our results in attempts to understand taxi traffic dynamics in NYC from multiple external data sources. We use four real-world ubiquitous urban datasets, including POIs, weather, geo-tagged tweets, and collision records. To address the heterogeneity of ubiquitous urban data, we present carefully-designed feature representations for these datasets. Our analysis suggests that POIs can well describe the regular traffic patterns. In addition, geo-tagged tweets can be used to explain irregular traffic caused by big events, and weather may account for abnormal traffic drops.

El presente estudio tuvo como proposito conocer el apoyo social que reciben las mujeres de familias monoparentales y compararlo con el de las mujeres que tienen conyuge (familias biparentales). La hipotesis fue que las primeras tienen menor apoyo social que las segundas. En un muestreo no probabilistico, la muestra se constituyo por 140 mujeres con hijos, 107 de familias biparentales y 33 de monoparentales, con un diseno transversal. Para medir apoyo social, se utilizo el cuestionario de Sherbourne y Stewart. La diferencia del apoyo de acuerdo al tipo de familia fue significativo, comprobandose la hipotesis inicial.
Multiple Access Class Barring Factors Algorithm for M2M Communications in LTE-advanced Networks

The forecast dramatic growth, of the number of Machine-to-Machine (M2M) communications, challenges the traditional networks of Mobile Network Operators (MNO). In fact, a large number of devices may attempt simultaneously to access the base station, which may result in severe congestions at the random-access channel (RACH) level. To alleviate such congestion while regulating the M2M devices' opportunities to transmit, the Access Class Barring (ACB) process was proposed. In this article, we proposed a novel implementation of the ACB mechanism in the context of multiple M2M traffic classes. Based on a scheduling algorithm, we have applied a PID controller to adjust dynamically multiple ACB factors related to each class category, guaranteeing a number of devices around an optimal value that maximizes the Random Access (RA) success probability. The obtained results demonstrate the efficiency of the proposed mechanism by increasing the success probability and minimizing radio resources' underutilization with respect to each class priority.
A Flexible Transparent Touch Panel Based on Ionic Liquid Channel

A flexible transparent touch panel based on conductive liquid channels is developed. The channel structures are monolithically produced in the transparent silicone resin by sacrificial etching. The height, width, and length of the flow channel are 0.017, 1.0, and 55 mm, respectively. The pitch of the channels is 10 mm. Ionic liquid as a conductive solution is introduced into the channels. The channel structures become almost invisible by filling the channel with the ionic liquid. Fabricated flexible transparent touch panels are mounted on both the flat and round surfaces, and the touch force detection is evaluated. The electrical resistances in both cases increases with increasing applied load until 6 N when a metal rod with a diameter of 5.0 mm is pushed against the surface of the touch panel.
Case finding for hepatitis C in primary care: a cost utility analysis.

BACKGROUND Hepatitis C is an important public health problem. The need for more intensified action to identify those infected with the virus has been recognized. Primary care is an important setting for case finding. OBJECTIVES To estimate the cost utility of case finding for hepatitis C in primary care, specifically amongst former injecting drug users (IDUs). METHODS A Markov model was developed to investigate the impact of case finding and treatment on progression of hepatitis C (HCV) in a hypothetical cohort of 1000 former IDUs. Comparison was made with a similar cohort in which no systematic case finding was implemented but spontaneous presentation for testing was allowed. Two scenarios were explored. The testing protocol utilized ELISA and PCR tests. Those eligible for treatment received combination therapy with pegylated interferon and ribavirin. Parameter estimates were obtained from literature searches and experts in the field. RESULTS Few estimates of the uptake of HCV testing in primary care are available. Cost utility was estimated at around 16,000 pounds sterling/QALY for both scenarios. At a willingness to pay of 30,000 pounds sterling/QALY, there is approximately a 75% probability that the initiatives would be cost-effective. Choices regarding the utility data, discounting and the rates of spontaneous/re-presentation outside of a case-finding programme appear to be important areas of uncertainty in this model. CONCLUSION Case finding for HCV in primary care is likely to be considered cost-effective but substantial uncertainties remain. Further research is needed on different approaches to case finding in primary care.
Meander line-based high impedance surface with high angular stability of resonant frequency

In this paper several kinds of high impedance surfaces (HISs) such as mushroom, Jerusalem cross-shaped HIS, spiral-shaped HIS and meander line-based HIS are analyzed. The sensitivity of reflection phases with respect to incident angles for TE and TM-polarized wave are compared. A meander line-based HIS has the least sensitivity to variation of the incident angles and operates at lower resonant frequency. The simulations show that the designed meander line based-HIS has a bandgap region between 4.83 to 6.82 GHz for TE and TM surface waves.
