Dual band inkjet printed bow-tie slot antenna on leather

A new dual band CPW fed bow-tie slot antenna on leather substrate is presented. The antenna is fabricated using inkjet printing directly on leather substrate. The dual band operation is achieved by loading the bow-tie slot antenna with bend slot stubs on the edges. The antenna operates at around 1.7 GHz and 2.9 GHz. The measured impedance bandwidth of the antenna in the two bands is 13.8% and 16.6%. It is the first ever antenna fabricated using inkjet printing on leather. The proposed antenna design is attractive for wearable and flexible electronic systems. A new concept of shoe radar for antipersonnel mine detection is presented which can utilize the proposed antenna.
The effects of Internet-based home training on upper limb function in adults with cerebral palsy.

BACKGROUND
While adults with hemiplegic cerebral palsy (CP) can have significant upper limb dysfunction, the effects of movement-based training has not been investigated.


OBJECTIVE
This uncontrolled trial assessed the effects of a home and internet-based upper limb intervention program targeting motor and sensory function.


METHODS
Twelve adults, aged 21 to 57 yrs, GMFCS levels I-III with asymmetric upper limb involvement participated in the Upper Limb Training and Assessment (ULTrA) program. Clinical and functional measures included the Motor Activity Log (MAL), the Nine-Hole Peg test, and grip strength. An upper limb training system consisting of a laptop, webcam, target light board, and hand manipulation/ discrimination devices was installed in each participant's home. Training occurred 40 min/day, 5 days/wk for 8 wks and included both unilateral and bilateral reach movements as well as a series of hand sensorimotor tasks such as card turning, stereognosis, and tactile discrimination. Data generated during each session were transmitted to the laboratory via the Internet.


MAIN OUTCOME MEASURES
were movement time, interlimb delay time, and performance on hand sensorimotor tasks.


RESULTS
Following training, affected limb reach movement time decreased significantly for unilateral and bilateral tasks. Interlimb delay during sequential reaching also decreased. Significant improvement in hand manipulation tasks was also seen. Compliance was excellent and there were no adverse effects.


CONCLUSION
The ULTrA program had beneficial effects for adults with CP and is safe and convenient to use. This system contrasts sharply with programs with similar intent that require participant travel and hours of therapist-based intervention.

The impact of cognitive absorption on perceived usefulness and perceived ease of use in on-line learning: an extension of the technology acceptance model

Internet-based learning systems are being used in many universities and firms but their adoption requires a solid understanding of the user acceptance processes. Our effort used an extended version of the technology acceptance model (TAM), including cognitive absorption, in a formal empirical study to explain the acceptance of such systems. It was intended to provide insight for improving the assessment of on-line learning systems and for enhancing the underlying system itself. The work involved the examination of the proposed model variables for Internet-based learning systems acceptance. Using an on-line learning system as the target technology, assessment of the psychometric properties of the scales proved acceptable and confirmatory factor analysis supported the proposed model structure. A partial-least-squares structural modeling approach was used to evaluate the explanatory power and causal links of the model. Overall, the results provided support for the model as explaining acceptance of an on-line learning system and for cognitive absorption as a variable that influences TAM variables. # 2004 Elsevier B.V.

ClariNet: Parallel Wave Generation in End-to-End Text-to-Speech

In this work, we propose an alternative solution for parallel wave generation by WaveNet. In contrast to parallel WaveNet (Oord et al., 2018), we distill a Gaussian inverse autoregressive flow from the autoregressive WaveNet by minimizing a novel regularized KL divergence between their highly-peaked output distributions. Our method computes the KL divergence in closed-form, which simplifies the training algorithm and provides very efficient distillation. In addition, we propose the first text-to-wave neural architecture for speech synthesis, which is fully convolutional and enables fast end-to-end training from scratch. It significantly outperforms the previous pipeline that connects a text-to-spectrogram model to a separately trained WaveNet (Ping et al., 2018). We also successfully distill a parallel waveform synthesizer conditioned on the hidden representation in this end-to-end model. 2
Recruitment and retention in obesity prevention and treatment trials targeting minority or low-income children: a review of the clinical trials registration database.

BACKGROUND
Efforts to recruit and retain participants in clinical trials are challenging, especially in studies that include minority or low-income children. To date, no studies have systematically examined recruitment and retention strategies and their effectiveness in working successfully with this population. We examined strategies employed to recruit or retain minority or low-income children in trials that included an obesity-related behavior modification component.


METHODS
First, completed home-, community-, and school-based trials involving minority or low-income children aged 2-17 years were identified in a search of the ClinicalTrials.gov registry. Second, a PubMed search of identified trials was conducted to locate publications pertinent to identified trials. Recruitment and retention rates were calculated for studies that included relevant information.


RESULTS
Our final analytic sample included 43 studies. Of these, 25 studies reported recruitment or retention strategies, with the amount of information varying from a single comment to several pages; 4 published no specific information on recruitment or retention; and 14 had no publications listed in PubMed. The vast majority (92 %) of the 25 studies reported retention rates of, on average, 86 %. Retention rates were lower in studies that: targeted solely Hispanics or African Americans (vs. mixed races of African Americans, whites, and others); involved children and parents (vs. children only); focused on overweight or obese children (vs. general children), lasted ≥1 year (vs. <1 year), were home or community-based (vs. school-based), included nutrition and physical activity intervention (vs. either intervention alone), had body mass index or other anthropometrics as primary outcome measures (vs. obesity-related behavior, insulin sensitivity, etc.). Retention rates did not vary based on child age, number of intervention sessions, or sample size.


CONCLUSIONS
Variable amounts of information were provided on recruitment and retention strategies in obesity-related trials involving minority or low-income children. Although reported retention rates were fairly high, a lack of reporting limited the available information. More and consistent reporting and systematic cataloging of recruitment and retention methods are needed. In addition, qualitative and quantitative studies to inform evidence-based decisions in the selection of effective recruitment and retention strategies for trials including minority or low-income children are warranted.
Expectations for discourse genre identification: a prosodic study

Speech can be divided into discourse genres based on the contextual environment it occurs in (e.g. political speech, sport commentary speech, etc.). The present study investigated whether listeners can distinguish between speech from different discourse genres on the basis of acoustic prosodic cues only 1. In a perception experiment with delexicalized speech 70 listeners with varying experience in French (native speakers, nonnative speakers, and non-speakers) were asked to identify four different types of discourse genres (church service, political, journal, and sport commentary). Results revealed a fair identification ability with a significant increase in performance with increasing experience in French. Identification confusion was used to cluster discourse genres according to their perceptual similarity.

Selective visual attention enables learning and recognition of multiple objects in cluttered scenes

A key problem in learning representations of multiple objects from unlabeled images is that it is a priori impossible to tell which part of the image corresponds to each individual object, and which part is irrelevant clutter. Distinguishing individual objects in a scene would allow unsupervised learning of multiple objects from unlabeled images. There is psychophysical and neurophysiological evidence that the brain employs visual attention to select relevant parts of the image and to serialize the perception of individual objects. We propose a method for the selection of salient regions likely to contain objects, based on bottom-up visual attention. By comparing the performance of David Lowe s recognition algorithm with and without attention, we demonstrate in our experiments that the proposed approach can enable one-shot learning of multiple objects from complex scenes, and that it can strongly improve learning and recognition performance in the presence of large amounts of clutter. 2005 Elsevier Inc.

On the Howe duality conjecture in classical theta correspondence

We give a proof of the Howe duality conjecture for the (almost) equal rank dual pairs in full generality. For arbitrary dual pairs, we prove the irreducibility of the (small) theta lifts for all tempered representations. Our proof works for any nonarchimedean local field of characteristic not 2 and in arbitrary residual characteristic.
A Methodology for Decompilation

A proposed methodology for decompilation of binary programs is presented, along with a description of a particular implementation of this methodology, dcc. dcc is a decompiler for the Intel 80x86 architecture, which takes as input a binary program from a DOS environment and produces C programs as output. The decompiler has been divided into three separate modules which resemble the structure of the compiler. The front-end module is machine dependent and performs the loading and parsing of the program, as well as the generation of an intermediate representation. The universal decompiling machine module is machine and language independent, and performs all the ow analysis of the program. Finally, the back-end module is language dependent and deals with the details of the target high level language. Even though the problem of decompilation is insoluble in general, a partial solution can be found, which gives information about the binary program. This paper describes some of the results found so far. [
Endoscopic gastritis, serum pepsinogen assay, and Helicobacter pylori infection

Endoscopic findings of the background gastric mucosa are important in the Helicobacter pylori-seroprevalent population. It is strongly correlated not only with the risk of gastric cancer, but also with the excretion ability of gastric mucosa cells. In noninfected subjects, common endoscopic findings are regular arrangement of collecting venules, chronic superficial gastritis, and erosive gastritis. In cases of active H. pylori infection, nodularity on the antrum, hemorrhagic spots on the fundus, and thickened gastric folds are common endoscopic findings. The secreting ability of the gastric mucosa cells is usually intact in both noninfected and actively infected stomachs, and the intragastric condition becomes hyperacidic upon inflammation. Increased serum pepsinogen II concentration correlates well with active H. pylori infection, and also indicates an increased risk of diffuse-type gastric cancer. In chronic inactive H. pylori infection, metaplastic gastritis and atrophic gastritis extending from the antrum (closed-type chronic atrophic gastritis) toward the corpus (open-type chronic atrophic gastritis) are common endoscopic findings. The intragastric environment is hypoacidic and the risk of intestinal-type gastric cancer is increased in such conditions. Furthermore, there is a decrease in serum pepsinogen I concentration when the secreting ability of the gastric mucosa cells is damaged. Serologic and endoscopic changes that occur upon H. pylori infection are important findings for estimating the secreting ability of the gastric mucosa cells, and could be applied for the secondary prevention of gastric cancer.
Efficacy, tolerability and safety in the treatment of chronic hepatitis C with combination of PEG-Interferon - Ribavirin in daily practice.

BACKGROUND
Efficacy and safety of Pegylated Interferon alfa (PegIFN)-Ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) in routine clinical practice seems to be comparable with results of randomized-controlled trials.


AIMS
To evaluate the efficacy, tolerability and safety of CHC treatment with PegIFN + RBV in .real world. patients in Argentina and to analyze factors associated with SVR.


METHODS
Medical records of patients treated according to current guidelines from 2001 to 2008 were reviewed.


RESULTS
235 patients were included and 80.8% completed treatment. Discontinuation occurred in 7.6% due to adverse events (AE), and 1.2% dropped-out treatment. Overall SVR was 60.8%. Multivariate analysis demonstrated that being naive (p 0.031) and low basal viral load (p 0.006) were associated with SVR, whereas F3-F4 (p 0.001) and elevated ALT (p 0.023) were associated with non-response. 80% of planned doses completed was associated with 74% SVR (p <0.001). At least one AE was reported in 93.6% of the patients: neutropenia in 27.6%, thrombocytopenia in 15.3%, anemia in 38.7%, psychiatric symptoms in 63.4%, thyroid dysfunction in 10.2%.


CONCLUSION
Efficacy, tolerability and safety of treatment of CHC in daily practice in Argentina are similar to those reported in randomized controlled trials.
Involvement of Abscisic Acid in Regulating Water Status in Phaseolus vulgaris L. during Chilling.

During the first hours of chilling, bean (Phaseolus vulgaris L., cv Mondragone) seedlings suffer severe water stress and wilt without any significant increase in leaf abscisic acid (ABA) content (P. Vernieri, A. Pardossi, F. Tognoni [1991] Aust J Plant Physiol 18: 25-35). Plants regain turgor after 30 to 40 h. We hypothesized that inability to rapidly synthesize ABA at low temperatures contributes to chilling-induced water stress and that turgor recovery after 30 to 40 h is mediated by changes in endogenous ABA content. Entire bean seedlings were subjected to long-term (up to 6 d) chilling (3 degrees C, 0.2-0.4 kPa vapor pressure deficit, 100 mumol.m(-2).s(-1) photosynthetic photon flux density, continuous fluorescent light). During the first 24 h, stomata remained open, and plants rapidly wilted as leaf transpiration exceeded root water absorption. During this phase, ABA did not accumulate in leaves or in roots. After 24 h, ABA content increased in both tissues, leaf diffusion resistance increased, and plants rehydrated and regained turgor. No osmotic adjustment was associated with turgor recovery. Following turgor recovery, stomata remained closed, and ABA levels in both roots and leaves were elevated compared with controls. The application of ABA (0.1 mm) to the root system of the plants throughout exposure to 3 degrees C prevented the chilling-induced water stress. Excised leaves fed 0.1 mm ABA via the transpiration stream had greater leaf diffusion resistance at 20 and 3 degrees C compared with non-ABA fed controls, but the amount of ABA needed to elicit a given degree of stomatal closure was higher at 3 degrees C compared with 20 degrees C. These findings suggest that endogenous ABA may play a role in ameliorating plant water status during chilling.
Absorption of calcium and magnesium in patients with intestinal resections treated with medium chain fatty acids.

BACKGROUND
Steatorrhoea is associated with increased faecal loss of calcium and magnesium. Medium chain C8-C10 triglycerides (MCTs) improve fat absorption in patients with small bowel resections but the effects on intestinal absorption of divalent cations are not clear.


AIM
To assess the effect of dietary replacement of long chain triglycerides (LCTs) with MCTs on calcium and magnesium absorption in patients with small bowel resections.


PATIENTS
Nineteen adult patients with a remaining small intestine averaging 171 cm (range 50-300).


METHODS
In a crossover design, patients were randomised to two high fat diets (10 MJ/day, 50% as fat) for four days each separated by one day of washout. Diets were prepared in duplicate and were based on either LCT (LCT period) or equal quantities of LCT and MCT (L/MCT period). Metabolic balances were calculated during the last three days of each period.


RESULTS
Mean stool volume increased significantly with the L/MCT diet and was 336 ml more than that with the LCT diet (95% confidence interval of mean difference, 26-649 ml). There was no significant change in the net absorption of calcium and magnesium between the two diets. On average, percentage calcium absorption was 8.6% with the LCT diet and 12.5% with the L/MCT diet. Mean percentage magnesium absorption was 5.4% with the LCT diet and 2.9% with the L/MCT diet.


CONCLUSIONS
Dietary replacement of 50% long chain triglycerides with medium chain triglycerides in small bowel resected patients increased faecal volume significantly. No changes in the intestinal net absorption of calcium and magnesium were demonstrated.
Why Respecting Physical Integrity Rights Reduces Terrorism

Does respect for human rights check or promote terrorism? This question is hotly debated within policy circles. Some hold that restricting human rights is a necessary if unfortunate cost of preventing terrorism. Others conclude that such abuses aggravate political grievances that contribute to terror. The authors demonstrate that theory and data support the latter position. They hypothesize that abuse of the subset of rights known as physical integrity rights fuels terrorism by making it more difficult for government authorities to collect intelligence on terrorists and by undermining domestic and international support for their counterterrorism efforts. They test this hypothesis using a data set that includes measures of both domestic and transnational terrorist attacks and find that respect for physical integrity rights is consistently associated with fewer terrorist attacks. This suggests that those interested in curtailing terrorism should press governments to more carefully respect physical integrity rights.
Cholesterol Metabolism in CKD.

Patients with chronic kidney disease (CKD) have a substantial risk of developing coronary artery disease. Traditional cardiovascular disease (CVD) risk factors such as hypertension and hyperlipidemia do not adequately explain the high prevalence of CVD in CKD. Both CVD and CKD are inflammatory states and inflammation adversely affects lipid balance. Dyslipidemia in CKD is characterized by elevated triglyceride levels and high-density lipoprotein levels that are both decreased and dysfunctional. This dysfunctional high-density lipoprotein becomes proinflammatory and loses its atheroprotective ability to promote cholesterol efflux from cells, including lipid-overloaded macrophages in the arterial wall. Elevated triglyceride levels result primarily from defective clearance. The weak association between low-density lipoprotein cholesterol level and coronary risk in CKD has led to controversy over the usefulness of statin therapy. This review examines disrupted cholesterol transport in CKD, presenting both clinical and preclinical evidence of the effect of the uremic environment on vascular lipid accumulation. Preventative and treatment strategies are explored.
