Robotic transtibial prosthesis with biomechanical energy regeneration

Purpose – The purpose of this paper is to describe a project which seeks to develop a new generation of powered prostheses based on lightweight, uniquely tuned, energy‐storing elastic elements in series with optimal actuator systems that will significantly reduce the peak power requirement of the motor and the total system energy requirement while providing the amputee 100 percent of required “push‐off” power and ankle sagittal plane range‐of‐motion comparable to able‐bodied gait.Design/methodology/approach – This paper presents the design, power, and energy‐efficiency analyses, and the results of a five‐month trial with one trans‐tibial amputee subject as part of the first phase of the Spring Ankle with Regenerative Kinetics project.Findings – The data show that by leveraging uniquely tuned springs and transmission mechanisms, motor power is easily amplified more than four fold and the electric energy requirement is cut in half compared with traditional approaches.Originality/value – This paper describes.
A physics-based compact model for FETs from diffusive to ballistic carrier transport regimes

This paper discusses a new emission-diffusion-based compact model for FETs to describe carrier transport in both short and long channel devices. The new model provides a description of the current at any drain bias without empirical fitting and predicts the injection velocity (device on-current). The new model is fully consistent with the widely used virtual-source model for describing transport in quasi-ballistic transistors. The accuracy of the new model is demonstrated by comparison with measured I-V data of III-V HEMTs and ETSOI silicon MOSFETs.
Signatures of a staggered-flux phase in the t − J model with two holes on a 32-site lattice

We study the relevance of the staggered-flux phase in the $t\ensuremath{-}J$ model using a system with two holes on a 32-site lattice with periodic boundary conditions. We find a staggered-flux pattern in the current-current correlation in the lowest energy d-wave state where there is mutual attraction between the holes. This staggered correlation decays faster with distance when the hole binding becomes stronger. This is in complete agreement with a recent study by Ivanov, Lee, and Wen [Phys. Rev. Lett. 84, 3958 (2000)] based on the SU(2) theory, and strongly suggests that the staggered-flux phase is a key ingredient in the $t\ensuremath{-}J$ model. We further show that this staggered-flux pattern does not exist in a state where the holes repel each other. Correlations of the chirality operator ${\mathbf{S}}_{1}\ensuremath{\cdot}({\mathbf{S}}_{2}\ifmmode\times\else\texttimes\fi{}{\mathbf{S}}_{3})$ show that the staggered pattern of the chirality is closely tied to the holes.
Statistical Machine Translation for Depassivizing German Part-of-speech Sequences

We aim to use statistical machine translation technology to correct grammar errors and style issues in monolingual text. Here, as a feasibility test, we focus on depassivization in German and we abstract from surface forms to parts of speech. Our results are not yet satisfactory but yield useful insights into directions for improvement.
Raman spectra of misoriented bilayer graphene

We compare the main feature of the measured Raman scattering spectra from single layer graphene with a bilayer in which the two layers are arbitrarily misoriented. The profiles of the 2D bands are very similar having only one component, contrary to the four found for commensurate Bernal bilayers. These results agree with recent theoretical calculations and point to the similarity of the electronic structures of single layer graphene and misoriented bilayer graphene. Another new aspect is that the dependance of the 2D frequency on the laser excitation energy is different in these two latter systems.
Sexuality and romantic relationships in young adult cancer survivors: satisfaction and supportive care needs

In recent years, psycho‐oncology has focused more and more on adolescents and young adults with cancer (AYA). Many studies have concentrated on fertility issues in AYAs, but romantic relationships and sexuality have only been researched to a limited extent. This cross‐sectional study examined AYAs' quality of relationships and sexuality satisfaction thereby identifying sex differences.
A simple and efficient MAC-routing integrated algorithm for sensor network

In sensor network the minimization of the power consumption is a fundamental key. Considering network with a number of wireless sensor spanning from hundreds to thousands, the complexity of the communication algorithm drives both the hardware requirement and the whole network cost. This paper is devoted to present a new communication algorithm able to merge the MAC and the routing mechanisms into a single layer. In such an algorithm each node has knowledge of its location and it uses this information in order to take decision on the path to reach the destination. The nodes has a sleeping capability to save energy, and an active node with pending packet selects, from the listening nodes in its coverage area, the best relay with respect to a given merit factor based on the distance to the destination and the remaining energy in such a relay. All the nodes are not coordinated and possible collisions during the relay selection may force to have a suboptimal relay use. In the paper this algorithm is described, analyzed and some simulation are performed in order to show its effectiveness. This system uses a single radio resource while a similar method proposed in Literature uses a busy tone approach with two radios and a different relay selection algorithm. Some comparisons with this more complex method is reported showing that the performance are very close in practical environment configuration, even if the complexity of our proposal is less.
Sparse Signal Aloha: A Compressive Sensing-Based Method for Uncoordinated Multiple Access

We investigate the problem of sparse signal medium access control in the wireless sensor networks. The proposed sparse signal Aloha (SSA) transmits sampled compressive data to the fusion center using Aloha random access protocol. In order to maximize the overall data transmission rate in the presence of packet collision, redundant data are randomly subsampled at individual sensor nodes according to an optimal subsampling rate before transmission. Data loss due to random subsampling and collision in the wireless channel are compensated using compressive sensing recovery method at the fusion center. Simulation results verify the theoretical analysis and show the significant improvement of SSA compared with existing CS-based random access method.
Increasing Coverage and Efficiency of Measles, Mumps, and Rubella Vaccine and Introducing Universal Varicella Vaccination in Europe: A Role for the Combined Vaccine

Universal mass vaccination according to a 2-dose measles-mumps-rubella (MMR) vaccine schedule is recommended by the World Health Organization and is fundamental to the control of these important diseases. Very high coverage (first dose, ≥95%; second dose, ≥80%) is necessary to achieve and sustain high population immunity, and eventually interrupt indigenous transmission of these diseases. In 2006, the Advisory Committee on Immunization Practices issued a recommendation for 2 doses of varicella vaccine to be given universally to children. Coadministration of MMR and varicella vaccines, though efficacious and well tolerated, can be difficult because of the 2 separate injections and associated compliance issues. In addition to the general advantages of a combined vaccine, recently registered measles-mumps-rubella-varicella (MMRV) vaccines could facilitate introduction of varicella universal mass vaccination by simplifying administration and providing the potential to achieve high coverage rates for these 4 diseases.
TEX template Evaluation of Support Vector Machines and Minimax Probability Machines for Weather Prediction

The paper evaluates two kernel-based methods on the problem of predicting precipitation based on observable variables. The support vector machine (SVM) method finds the two parallel hyperplanes that provide maximal separation of two subsets, excepting outliers. The minimax probability machine (MPM) method finds an optimal separating hyperplane that minimizes the probability of misclassification. Both SVM and MPM are binary classification methods that can be extended easily to multiclass problems. Both make use of the “kernel trick” to transform a linearly inseparable problem into a higher dimensional space where the problem may be linearly separable. The paper also investigates the accuracy and Peirce Skill Score (PSS, also known as the Hanssen and Kuipers discriminant) measures resulting from adding derived variables and removing variables. Using cross validation on the training data the accuracy was 70% and PSS 47%. On the final testing data the PSS was 35%.
Liver transplantation for alcoholic hepatitis: A systematic review with meta-analysis

Background The rate of alcohol relapse among patients who underwent liver transplantation for alcoholic hepatitis (AH) is not precisely known. Aim Synthesize the available evidence on liver transplantation for AH to assess alcohol relapse and 6-month survival. Methods Meta-analysis of trials evaluating liver transplantation for AH, either clinically severe or diagnosed on the explant. Results Eleven studies were included. The pooled estimate rate for alcohol relapse was 0.22 (95% CI = 0.12–0.36) in overall analysis with high heterogeneity between studies (I2 = 76%), 0.20 (95% CI = 0.07–0.43) in the subgroup analysis including patients with clinically severe AH (I2 = 84%), 0.14 (95% CI = 0.08–0.23) among patients with clinically severe AH in sensitivity analysis excluding the discrepant studies that did not use stringent selection criteria for liver transplantation (I2 = 0%), and 0.15 (95% CI = 0.07–0.27) for recurrent harmful alcohol consumption among patients with clinically severe AH (I2 = 3%). The risk of alcohol relapse was not different between AH transplanted patients and patients with alcoholic cirrhosis who underwent elective liver transplantation in sensitivity analysis excluding the discrepant studies (OR = 1.68, 95%CI = 0.79–3.58, p = 0.2, I2 = 16%). The pooled estimate rate for 6-month survival was 0.85 (95% CI = 0.77–0.91, I2 = 49%), and 0.80 among patients transplanted for clinically severe AH (95% CI = 0.69–0.88, I2 = 30%). AH transplanted patients had similar 6-month survival to patients with alcoholic cirrhosis who underwent elective liver transplantation (OR = 2.00, 95% CI = 0.95–4.23, p = 0.07, I2 = 0%). Conclusion Using stringent selection criteria, 14% of patients with clinically severe AH have alcohol relapse after liver transplantation. The percentage of alcohol relapse of AH transplanted patients is similar than that of patients who underwent elective liver transplantation.
Salivary function in patients with reflux esophagitis: effect of cisapride.

UNLABELLED Saliva plays an important role in esophageal acid clearance. Reduction in salivary function has been considered in the pathogenesis of reflux esophagitis. Cisapride, a prokinetic agent, has been reported effective for treating mild-to-moderate grade gastroesophageal reflux disease. Some studies have shown that cisapride increases saliva volume and acid-buffering capacity. The aim of this study was to evaluate the effect of cisapride on salivary gland function by means of dynamic salivary scintigraphy. METHODS Fifty-five patients with endoscopic reflux esophagitis (Savary-Miller Grades I-II) were enrolled in this study. In Group 1 (n = 29), patients were evaluated during the fasting state, both before and after cisapride treatment (5 mg, 3 times/day, before meals, for 2 wk). In Group 2 (n = 26), patients were evaluated during the postprandial state, both before and after cisapride treatment. Uptake ratio (UR) and excretion ratio (ER) of the salivary gland in each group were compared using the paired Student's t-test. RESULTS In Group 1, no significant differences were found in UR or ER after cisapride treatment. However, in Group 2, ER increased significantly after treatment (p < 0.01), but UR did not show any significant change. CONCLUSION Cisapride can increase the secretion function of salivary glands during the postprandial phase but not the fasting phase.
The Economic Consequences of Organized Crime: Evidence from Southern Italy

I examine the post-war economic growth of two regions in southern Italy exposed to the presence of maa organizations after the 1970s and apply synthetic control methods to estimate their counterfactual growth performance in the absence of organized crime. The synthetic control is a weighted average of Italian regions less aected by maa activity that mimics the economic structure and outcomes of the regions of interest several years before the presence of criminal organizations. The comparison of actual and counterfactual development shows that the presence of maa lowers regional GDP per capita by 16%, at the same time as murders increase sharply relative to the synthetic control. Historical series of electricity consumption suggest that lower GDP reects a net loss of economic activity, rather than a mere reallocation from the ocial to the unocial sector. Growth accounting attributes the slowdown to the substitution of private capital with less productive public investment after the advent of organized crime.

Last, the CANDISC variable reduction method with ANN classification model utilized in the study is applied.Findings – The supplier selection model designed with ANN classification model and fuzzy scales will be more effective than with the traditional statistics analysis.Research limitations/implications – The new paradigm for decision making includes a combination of several effect.
Thin-film composite resonators on crystalline substrates

Telecommunications systems depend on high stability frequency sources. For mobile uses such as cell phones, size and cost are severe additional constraints. We describe a class of composite piezoresonators that are comprised of piezoelectric thin films deposited on crystalline plate substrates [1] oriented to obtain very low temperature coefficients of frequency (TCFs) for the composite structure. Specifically described are highfrequency bulk acoustic wave resonators (HBARs) comprised of piezoelectric thin films on ATand BT-cut quartz substrates. An example design for a 2.1 GHz composite resonator is provided.
Next Generation More-Electric Aircraft: A Potential Application for HTS Superconductors

Sustainability in the aviation industry calls for aircraft that are significantly quieter and more fuel efficient than today's fleet. Achieving this will require revolutionary new concepts, in particular, electric propulsion. Superconducting machines offer the only viable path to achieve the power densities needed in airborne applications. This paper outlines the main issues involved in using superconductors for aeropropulsion. We review our investigation of the feasibility of superconducting electric propulsion, which integrate for the first time, the multiple disciplines and areas of expertise needed to design electric aircraft. It is shown that superconductivity is clearly the enabling technology for the more efficient turbo-electric aircraft of the future.
Managing Late Measurements in Data Warehouses

Though in most data warehousing applications no relevance is given to the time when events are recorded, some domains call for a different behavior. In particular, whenever late measurements of events take place, and particularly when the events registered are subject to further updates, the traditional design solutions fail in preserving accountability and query consistency. In this article, we discuss the alternative design solutions that can be adopted, in presence of late measurements, to support different types of queries that enable meaningful historical analysis. These solutions are based on the enforcement of the distinction between transaction time and valid time within the schema that represents the fact of interest. Besides, we provide a qualitative and quantitative comparison of the solutions proposed, aimed at enabling wellinformed design decisions.
Colorectal Adenomas.

Since the last review of colorectal adenomas in the Journal,1 a wealth of new data has emerged that is improving our understanding of their clinical significance. In the past 10 years, several large studies, performed predominantly in the United States, have evaluated persons at average risk for colorectal adenomas. The new evidence that these studies have provided regarding the biology of adenomas, their prevalence and incidence, the relevance of risk profiles, and controversies in screening and surveillance is germane to clinical decisions and identifies potential targets for the improved management of these important premalignant lesions.
Hormonal Effects on Epilepsy in Women

Summary: Some female gonadal and adrenal steroid hor‐mones and their related pituitary peptides have neuroactive effects that can influence seizures. These effects may play a significant role in the pathophysiology of epilepsy, the pattern of seizure occurrence, therapeutic interventions using naturally occurring hormones, and the development of hormone‐based neuroactive synthetic analogues with potent antiepileptic properties.
A Re-router for Reducing Wire Length in Multi- Layer No-Dogleg Channel Routing

— The minimization of total wire length is one of the most key issue in VLSI physical design automation, as it reduces the cost of physical wiring required along with the electrical hazards of having long wires in the interconnection, power consumption, and signal propagation delay. So, it is still important as cost as well as high performance issue. The problem of reduced wire length routing solutions in no-dogleg reserved two-layer (VH) and multi-layer (V i H i , 2 ≤ i < d max and V i H i+1 , 2 ≤ i < d max − 1) channel routing is NP-hard, so, it is interesting to develop heuristic algorithms that compute routing solutions of as minimum total (vertical) wire length as possible. Here we propose two algorithms to reduce the total (vertical) wire length in channel routing problem. First we develop an efficient re-router Further_Reduced_Wire_Length (FRWL) to optimize the wire length in the reserved two-layer (VH) no-dogleg channel routing model and then we develop an algorithm Multi-Layer_Reduced_Wire_Length (MLRWL) to minimize the total (vertical) wire length in channel routing problem in the reserved multi-layer (V i H i , 2 ≤ i < d max and V i H i+1 , 2 ≤ i < d max − 1) no-dogleg Manhattan routing models, where vertical and horizontal layers of interconnect alternate. Experimental results computed for available benchmark instances indicate that the algorithms perform well.

Apolipoprotein A‐I deficiency does not affect biliary lipid secretion and gallstone formation in mice

Background/Aims: Apolipoprotein A‐I (apo A‐I) is the main protein component of plasma high‐density lipoproteins (HDL) and a key determinant of HDL cholesterol levels and metabolism. The relevance of HDL in controlling the traffic of cholesterol from plasma into bile has been partially addressed. The aim of this study was to evaluate the role of apo A‐I expression in controlling the secretion of biliary lipids as well as the risk of gallstone disease in vivo.
Exploring the effect of customers' perceptions of electronic retailer ethics on revisit and purchase intention of retailer website

By advances in technology and the advent of the Age of Communication and Information, observed that physical stores are replaced by electronic stores. Of course, this is more evident in the case of some products and industry so that some products than can be obtained from their physical stores, can provide from electronics stores and via the Internet now. Electronic retail expansion has been accompanied by discussions and new issues and Customers have special attention to these issues; one of the items discussed are ethics. Because customer and electronic seller don't have Face to face contacts, Ethics are very important. It is better to focus on ethics and trust of customers, encouraged them to revisit the website and repurchase. This research proposed model about customer perception of electronic retailer' ethics and its impact on revisit and repurchase intention from retailer's website and tested it among the customers who purchase products electronically from some websites.

Apparitional Experiences of New Faces and Dissociation of Self-Identity during Mirror Gazing

Apparitional experiences during mirror gazing were studied. Under low levels of illumination, individuals gazed at their own reflected faces in a mirror for a duration of 10 min. Face illumination was relatively uniform, via a nonvisible light source. After about a minute of mirror gazing, individuals reported perceiving strange faces — archetypical and often unknown, human or animal, living or departed parents with traits changed, and fantastical monstrous beings — instead of their own faces in the mirror. During these apparitions, the observers reported feeling that a strange person was watching them from within or beyond the mirror, while the observer maintained consciousness of himself looking at the strange “other. ” Three psychophysical experiments were conducted on 42 naïve normal individuals. At an illumination of the face around 0.8 lux, the mean frequency of apparitions was 1.8 min.−1 and mean duration was 7 sec. per apparition. At higher illumination, the frequency of apparitional experiences decreased while the duration of mirror gazing needed for the phenomenon to occur increased. This effect may be termed “conscious dissociation of self-identity” to distinguish it from pathological unconscious dissociative identity disorder.
