A Class-F Power Amplifier With CMRC

This letter presents a novel harmonic control circuit (HCC) for class-F power amplifiers (PAs). A compact microstrip resonant cell (CMRC) is inserted between the transistor and the output fundamental matching network. Third harmonic open circuit condition and size reduction are achieved simultaneously. This scheme provides a straightforward and simple approach to design HCC. A class-F PA is designed and fabricated for demonstration. The measured maximum power-added efficiency (PAE) is 74% with 10 dB power gain near the 1 dB compression point.
Simple GUI Wireless Controller of Quadcopter

This paper presents the development of remotely operated Quadcopter system. The Quadcopter is controlled through a graphical user interface (GUI) where the communication between GUI and Quadcopter is constructed by using wireless communication system. The Quadcopter balancing condition is sensed by FY90 controller and IMU 5DOF sensor. For smooth landing, Quadcopter is equipped with ultrasonic sensor. All signals from sensors are processed by Arduino Uno microcontroller board and output from the Arduino Uno microcontroller board is implemented to control Quadcopter propellers. The GUI is designed using Visual Basic 2008 Express as interfacing communication between the Proportional, Integral and Derivative (PID) controller and the Quadcopter system. The experiment shows that the Quadcopter system can hover while maintain it balancing and the stability is guaranteed. Moreover, the developed system is able to cope with load disturbance up to 250 gduring the hover position. Maximum operated time of Quadcopter is six minutes using 2200 mAh Lipo battery and operate time can be increased by using largest battery capacity.
Sec61p mediates export of a misfolded secretory protein from the endoplasmic reticulum to the cytosol for degradation

Degradation of misfolded secretory proteins has long been assumed to occur in the lumen of the endoplasmic reticulum (ER). Recent evidence, however, suggests that such proteins are instead degraded by proteasomes in the cytosol, although it remains unclear how the proteins are transported out of the ER. Here we provide the first genetic evidence that Sec61p, the pore‐forming subunit of the protein translocation channel in the ER membrane, is directly involved in the export of misfolded secretory proteins. We describe two novel mutants in yeast Sec61p that are cold‐sensitive for import into the ER in both intact yeast cells and a cell‐free system. Microsomes derived from these mutants are defective in exporting misfolded secretory proteins. These proteins become trapped in the ER and are associated with Sec61p. We conclude that misfolded secretory proteins are exported for degradation from the ER to the cytosol via channels formed by Sec61p.

Evolution of GERD over 5 years

ileum) should be considered to be ‘extensive disease’ (L3 in the Montreal classification). The data concerning risk of surgery were presented as cumulative 5-year-risks and not in Kaplan–Meier curves due to lack of space. The follow-up periods were 5.2 and 5.0 years (medians) for CD and UC, respectively. Cox-regression analysis was used in the analysis of the cumulative surgery risk. All patients were censored at last follow-up, or at date of surgery, whichever came first. We feel this to be a statistically sound presentation of our results. We believe that our results contribute in an original, as well as valid, way to the so far sparse literature dealing with comparison of paediatric and adult IBD.
Concept-Driven Interaction Design Research

In this article, we explore a concept-driven approach to interaction design research with a specific focus on theoretical advancements. We introduce this approach as a complementary approach to more traditional, and well-known, user-centered interaction design approaches. A concept-driven approach aims at manifesting theoretical concepts in concrete designs. A good concept design is both conceptually and historically grounded, bearing signs of the intended theoretical considerations. In the area of human–computer interaction and interaction design research, this approach has been quite popular but not necessarily explicitly recognized and developed as a proper research methodology. In this article, we demonstrate how a concept-driven approach can coexist, and be integrated with, common user-centered approaches to interaction design through the development of a model that makes explicit the existing cycle of prototyping, theory development, and user studies. We also present a set of basic principles that could constitute a foundation for concept driven interaction research, and we have considered and described the methodological implications given these principles. For the field of interaction design research we find this as an important point of departure for taking the next step toward the construction and verification of theoretical constructs that can help inform and guide future design research projects on novel interaction technologies.
Serum Levels of Female Sex Hormones in Left-handed and Right-handed Menopausal Women

The study covered 25 left-handed and 27 right-handed clinically healthy females aged between 47 and 55 years during normal menopause. It was carried out in the third year from the beginning of amenorrhoea. The levels of the follicle-stimulating hormone, luteinising hormone, proclactin, estradiol, and progesterone were determined by means of enzyme-immunological methods with IMX (Abbott, USA) and Serozyme I (Biochem Immunosystem Diagnostica, USA) apparatuses. It was established that in left-handed women the serum concentrations both of the follicle-stimulating hormone and luteinising hormone were significantly higher (P <.001), and those of prolactin, estradiol, and progesterone much lower (P <.001), as compared to the right-handed women.
Investigating in-domain data requirements for PLDA training

This paper analyzes the limitations upon the amount of in- domain (NIST SREs) data required for training a probabilistic linear discriminant analysis (PLDA) speaker verification system based on out-domain (Switchboard) total variability subspaces. By limiting the number of speakers, the number of sessions per speaker and the length of active speech per session available in the target domain for PLDA training, we investigated the relative effect of these three parameters on PLDA speaker verification performance in the NIST 2008 and NIST 2010 speaker recognition evaluation datasets. Experimental results indicate that while these parameters depend highly on each other, to beat out-domain PLDA training, more than 10 seconds of active speech should be available for at least 4 sessions/speaker for a minimum of 800 speakers. If further data is available, considerable improvement can be made over solely out-domain PLDA training.
Hardware-oriented feature extraction based on compressive sensing

Feature extraction is used to reduce the amount of resources required to describe a large set of data. A given feature can be represented by a matrix having the same size as the original image but having relevant values only in some specific points. We can consider this sets as being sparse. Under this premise many algorithms have been generated to extract features from compressive samples. None of them though is easily described in hardware. We try to bridge the gap between compressive sensing and hardware design by presenting a sparsifying dictionary that allows compressive sensing reconstruction algorithms to recover features. The idea is to use this work as a starting point to the design of a smart imager capable of compressive feature extraction. To prove this concept we have devised a simulation by using the Harris corner detection and applied a standard reconstruction method, the Nesta algorithm, to retrieve corners instead of a full image.
Physics and chemistry of photocatalytic titanium dioxide: visualization of bactericidal activity using atomic force microscopy

When titanium dioxide (TiO 2 ) is exposed to near-ultraviolet light, it exhibits strong bactericidal activity. Anatase phase of TiO 2 film was prepared by anodizing pure titanium coupons (substrate). Atomic force microscopy (AFM) technique was used to image the transformation of titanium surface to TiO 2 surface on anodization. We observed wide distribution of TiO 2 particles ranging from submicron to nanometre sizes, fully covering the substrate forming a thin film on anodizing. With the formation of a thin film of TiO 2 , we observed strong bactericidal activity. Bactericidal activity was attributed to the well-known photocatalytic property of the semiconductor TiO 2 . Here we present some arguments for reasoning out why certain semiconducting metal oxides exhibit photocatalytic properties and some do not. We also present some of the important elementary reaction steps considering adsorbed oxygen and water molecule as necessary molecules for the photooxidation process. Other reactions involved in producing reactive oxygen species and hydroxyl radical are presented to understand the process involved in photocatalytic biocidal activity. Finally, we present visualization of photocatalytic bactericidal activity of TiO 2 using AFM.
Association of cross-cultural differences in psychiatric morbidity with cultural values: A secondary data analysis

Background: Associations were analyzed between cultural values/attitudes and psychiatric morbidity/health complaints in different cultures, drawing on data from two independent cross-cultural studies. It was assumed that cross-cultural differences in psychiatric disorders and health complaints could be related to differences in cultural values. Specifically, it was assumed that more traditional values are related to lower prevalences of psychiatric morbidity. Methods: Data from (1) a multi-center study on cultural values (Schwartz, 1994) and (2) the World Health Organization (WHO) Collaborative Study on Psychological Problems in General Health Care (Üstün & Sartorius, 1995) were jointly analyzed. Six cultural values (autonomy, conservatism, preference for hierarchy, self-mastery, egalitarian commitment, and harmony with nature) were related to regionally corresponding data on psychiatric morbidity (ICD-10 diagnoses) and types of symptoms presented (Üstün & Sartorius, 1995). Data of eleven countries constitute the unit of analysis. Results: By and large, values representative of traditional societies (conservatism, hierarchy, and selfmastery) were negatively correlated with psychiatric diagnoses and symptoms, whereas values typical of modern/postmodern societies (autonomy and egalitarian commitment) were positively correlated with psychiatric diagnoses and symptoms. Ordinal regression analysis explained moderate to high levels of cross-cultural variance by cultural values. Conclusions: The explorative study indicates that psychiatric morbidity and cultural values may be closely intertwined. Possible theoretical explanations and implications as well as limitations of the current analyses are discussed (German J Psychiatry 2001; 4:17-23) .
Modelling predation as a capped rate stochastic process, with applications to fish recruitment

Many mathematical models use functions the value of which cannot exceed some physically or biologically imposed maximum value. A model can be described as ‘capped-rate’ when the rate of change of a variable cannot exceed a maximum value. This presents no problem when the models are deterministic but, in many applications, results from deterministic models are at best misleading. The need to account for stochasticity, both demographic and environmental, in models is therefore important but, as this paper shows, incorporating stochasticity into capped-rate models is not trivial. A method using queueing theory is presented, which allows randomness and spatial heterogeneity to be incorporated rigorously into capped rate models. The method is applied to the feeding and growth of fish larvae.
A systematic review of stress-management interventions for multiple sclerosis patients.

BACKGROUND The objective of this study was to identify stress-management interventions used for people with multiple sclerosis (MS) and systematically evaluate the efficacy of these interventions. METHODS Several strategies were used to search for studies reported in articles published up to 2013. RESULTS Our initial search retrieved 117 publications, of which 8 met our criteria for review. Of the eight studies, one provided Class I evidence, five provided Class III evidence, and two provided Class IV evidence for the efficacy of stress-management interventions according to the evidence classification established by the American Academy of Neurology. Most studies showed positive changes in outcomes assessed; however, the range of methodological quality among the published studies made it difficult to draw conclusions. CONCLUSIONS The promising findings for stress-management interventions highlight the need for future studies. Additional large, prospective, multicenter studies will help to define the role of stress-management interventions in the treatment and course of MS. Furthermore, including outcome measures based on biological and clinical markers of disease will prove useful in understanding potential underlying mechanisms.
A Dual Reservation MAC Protocol based on CDMA for Ad hoc Networks

Multi-channel research in wireless ad hoc networks has drawn more attention in recent years. Several MAC protocols have been proposed for multi-channel access. However, they either suffer from additional hardware and algorithm cost or weak broadcast support. In this paper, a dual reservation MAC protocol based on CDMA (DRMC) is proposed to solve those problems. Code synchronization is dynamically implemented through RTS/CTS handshake. Once communication is set up, both sides can reserve resource through piggyback. And furthermore, broadcast messages are well supported by an out-of-band busy tone. According to simulation results, we have validated that DRMC performs significantly better than IEEE 802.11 standard which provides multiple channels while its MAC is still designed for a single channel
Frailty and Cognitive Function in Incident Hemodialysis Patients.

BACKGROUND AND OBJECTIVES Patients of all ages undergoing hemodialysis (HD) have a high prevalence of cognitive impairment and worse cognitive function than healthy controls, and those with dementia are at high risk of death. Frailty has been associated with poor cognitive function in older adults without kidney disease. We hypothesized that frailty might also be associated with poor cognitive function in adults of all ages undergoing HD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS At HD initiation, 324 adults enrolled (November 2008 to July 2012) in a longitudinal cohort study (Predictors of Arrhythmic and Cardiovascular Risk in ESRD) were classified into three groups (frail, intermediately frail, and nonfrail) based on the Fried frailty phenotype. Global cognitive function (3MS) and speed/attention (Trail Making Tests A and B [TMTA and TMTB, respectively]) were assessed at cohort entry and 1-year follow-up. Associations between frailty and cognitive function (at cohort entry and 1-year follow-up) were evaluated in adjusted (for sex, age, race, body mass index, education, depression and comorbidity at baseline) linear (3MS, TMTA) and Tobit (TMTB) regression models. RESULTS At cohort entry, the mean age was 54.8 years (SD 13.3), 56.5% were men, and 72.8% were black. The prevalence of frailty and intermediate frailty were 34.0% and 37.7%, respectively. The mean 3MS was 89.8 (SD 7.6), TMTA was 55.4 (SD 29), and TMTB was 161 (SD 83). Frailty was independently associated with lower cognitive function at cohort entry for all three measures (3MS: -2.4 points; 95% confidence interval [95% CI], -4.2 to -0.5; P=0.01; TMTA: 12.1 seconds; 95% CI, 4.7 to 19.4; P<0.001; and TMTB: 33.2 seconds; 95% CI, 9.9 to 56.4; P=0.01; all tests for trend, P<0.001) and with worse 3MS at 1-year follow-up (-2.8 points; 95% CI, -5.4 to -0.2; P=0.03). CONCLUSIONS In adult incident HD patients, frailty is associated with worse cognitive function, particularly global cognitive function (3MS).
Optimum multi-user detection in ultra-wideband (UWB) multiple-access communication systems

This paper investigates multi-user detection in multiple-access communication systems based on ultrawideband (UWB) technology. As user numbers increase and the bandwidth to pulse repetition frequency (PRF) decreases, multiple-access interference (MAI) is expected to adversely affect system capacity and performance. The paper presents a framework for the design of multi-user detectors and proposes the optimum multi-user detector for UWB. Numerical examples illustrate the performance of the optimum detector versus that of the conventional single-user UWB detector.
A novel procedure for protein extraction from formalin‐fixed paraffin‐embedded tissues

Most of the archived pathological specimens in hospitals are kept as formalin‐fixed paraffin‐embedded tissues (FFPE) for long‐term preservation. Up to now, these samples are only used for immunohistochemistry in a clinical routine as it is difficult to recover intact protein from these FFPE tissues. Here, we report a novel, short time‐consuming and cost‐effective method to extract full‐length, non‐degraded proteins from FFPE tissues. This procedure is combined with an effective and non‐toxic deparaffinisation process and an extraction method based on antigen‐retrieval, high concentration of SDS and high temperature. We have obtained enough intact protein to be detected by Western blotting analysis. This technique will allow utilising these stored FFPE tissues in several applications for protein analysis helping to advance the translational studies in cancer and other diseases.
Use of complementary and alternative medical therapies among racial and ethnic minority adults: results from the 2002 National Health Interview Survey.

PURPOSE Complementary and alternative medicine (CAM) use among ethnic minority populations is poorly understood. We sought to examine CAM use in Hispanics, non-Hispanic blacks and non-Hispanic whites. METHODS We analyzed data from the Alternative Health Supplement to the 2002 National Health Interview Survey (NHIS), including information on 19 different CAM therapies used in the past 12 months. RESULTS An estimated 34% of Hispanic, non-Hispanic black and non-Hispanic white adults in the United States used at least one CAM therapy (excluding prayer) during the prior 12 months (2002). CAM use was highest for non-Hispanic whites (36%), followed by Hispanics (27%) and non-Hispanic blacks (26%). Non-Hispanic whites were more likely to use herbal medicine, relaxation techniques and chiropractic more frequently than Hispanics and non-Hispanic blacks. After controlling for other sociodemographic factors, Hispanic and non-Hispanic black races/ethnicities were associated with less CAM use, with adjusted odds ratios (95% confidence intervals) of 0.78 (0.70, 0.87) and 0.71 (0.65, 0.78), respectively. Hispanics cited using CAM because conventional medical treatments were too expensive more frequently than non-Hispanic blacks or whites. Hispanics had the highest provider nondisclosure rates (68.5%), followed by non-Hispanic blacks (65.1%) and non-Hispanic whites (58.1%). CONCLUSIONS Excluding prayer, Hispanics and non-Hispanic blacks used CAM less frequently than non-Hispanic whites and were less likely to disclose their use to their healthcare provider. Further research is needed to improve our understanding of the disparities in CAM use.
Chemokine expression in Th 1 cell-induced lung injury : prominence of IFN-g-inducible chemokines

Dixon, Anne E. , Janis B. Mandac, David K. Madtes, Paul J. Martin, and Joan G. Clark. Chemokine expression in Th1 cell-induced lung injury: prominence of IFN-g-inducible chemokines. Am J Physiol Lung Cell Mol Physiol 279: L592–L599, 2000. —Proinflammatory responses generated by T helper type 1 (Th1) cells may contribute significantly to immune-mediated lung injury. We describe a murine model of Th1 cell-induced lung injury in which adoptive transfer of alloreactive Th1 cells produces pulmonary inflammation characterized by mononuclear cell vasculitis, alveolitis, and interstitial pneumonitis. To investigate the link between activation of Th1 cells in the lung and inflammatory cell recruitment, we characterized cytokine and chemokine mRNA expression in Th1 cells activated in vitro and in lung tissue after adoptive transfer of Th1 cells. Activated Th1 cells per se express mRNA for interferon (IFN)-g and several members of the tumor necrosis factor family as well as the C-C chemokine receptor-5 ligands regulated on activation normal T cells expressed and secreted and macrophage inflammatory protein-1a and -1b. Additional chemokine genes were induced in the lung after Th1 cell administration, most notably IFN-g-inducible protein (IP-10) and monokine induced by IFN-g (MIG). Remarkable increases in IP-10and MIG-immunoreactive proteins were present in inflammatory foci lung and identified in macrophages, endothelium, bronchial epithelium, and alveolar structures. The findings suggest that IFN-g-inducible chemokines are an important mechanism for amplifying inflammation initiated by Th1 cells in the lung.
A prosody inspired RNN approach for punctuation of machine produced speech transcripts to improve human readability

Speech communication human-machine interfaces exploit automatic speech recognition to implement speech-to-text conversion. Unfortunately, in the past, not much effort has been devoted to add punctuation marks to the recognized word chain after speech recognition. This affects human readability and makes interpretation hard. This paper presents an effort to restore punctuation marks by keeping low the latency resulting from this post-processing step. The approach exploits the prosodic structure and proposes a sequential modelling paradigm based on recurrent neural networks. Results show satisfying punctuation restoration abilities, especially taking into account that sentence boundaries are reliably detected. Even if the predicted punctuation sequence is not error free w.r. t. writing standards, human perception is expected to “repair” these errors more easily compared to the case when no punctuation is given at all and the reader is left in confusion regarding the basic segmentation of the word chain.
