Designing optical square resonator based filter and stability analysis

Design of Optical double square resonator, with constituent waveguide material as Silicon-on-Insulator, based optical filter and its stability analysis has been stated in this work. The frequency response has been analyzed using delay line signal processing technique in z-domain and Mason's gain formula. On the basis of Vernier principle enhanced free spectral range has been obtained as much as 219.2 THz for drop port transmittance that is suited for THz communication in C-band. Here interstitial spurious transmission is around −100dB with negligible resonance loss. Round off noise power spectrum characteristics, depth of modulation, group delay are also determined for this architecture.

Complementary source based circularly polarized antenna arrays for millimeter-wave applications

Circularly-polarized 2-by-2 antenna arrays based on the complementary source concept are designed for millimeter-wave applications at 60 GHz. Each antenna element consists of a slot and an electric dipole. Energy is coupled from a microstrip feeding network to the slots. Each slot radiates and simultaneously excites the dipole, achieving a complementary source. Two arrays are presented to demonstrate the design methodology.
Diagnosis of goose circovirus infection in Hungarian geese samples using polymerase chain reaction and dot blot hybridization tests

A polymerase chain reaction (PCR) and dot blot hybridization (DBH) test have been developed for the diagnosis of infection by a novel circovirus of geese (GoCV). These tests were applied to samples of bursae of Fabricius from sick and dead birds from commercial goose farms in Hungary. In this second report of the occurrence of circovirus infection in diseased geese, 103 of 214 (48.1%) and 37 of 150 (24.6%) birds, and 49 of 76 (64.5%) and 18 of 76 (23.7%) flocks were positive by PCR and DBH respectively. The sensitivity of the PCR test was such that 0.10 fg of virus DNA was detectable. The DBH test was less sensitive, only detecting larger amounts (40 pg) of DNA, but was used as a semi-quantitative method for detecting the presence of virus. The incidence of infection was affected by factors such as the age of the birds and rearing methods.
Does stretching increase ankle dorsiflexion range of motion? A systematic review

Background: Many lower limb disorders are related to calf muscle tightness and reduced dorsiflexion of the ankle. To treat such disorders, stretches of the calf muscles are commonly prescribed to increase available dorsiflexion of the ankle joint. Hypothesis: To determine the effect of static calf muscle stretching on ankle joint dorsiflexion range of motion. Study design: A systematic review with meta-analyses. Methods: A systematic review of randomised trials examining static calf muscle stretches compared with no stretching. Trials were identified by searching Cinahl, Embase, Medline, SportDiscus, and Central and by recursive checking of bibliographies. Data were extracted from trial publications, and meta-analyses performed that calculated a weighted mean difference (WMD) for the continuous outcome of ankle dorsiflexion. Sensitivity analyses excluded poorer quality trials. Statistical heterogeneity was assessed using the quantity I2. Results: Five trials met inclusion criteria and reported sufficient data on ankle dorsiflexion to be included in the meta-analyses. The meta-analyses showed that calf muscle stretching increases ankle dorsiflexion after stretching for ⩽15 minutes (WMD 2.07°; 95% confidence interval 0.86 to 3.27), >15–30 minutes (WMD 3.03°; 95% confidence interval 0.31 to 5.75), and >30 minutes (WMD 2.49°; 95% confidence interval 0.16 to 4.82). There was a very low to moderate statistical heterogeneity between trials. The meta-analysis results for ⩽15 minutes and >15–30 minutes of stretching were considered robust when compared with sensitivity analyses that excluded lower quality trials. Conclusions: Calf muscle stretching provides a small and statistically significant increase in ankle dorsiflexion. However, it is unclear whether the change is clinically important.
Annotation of the Arabidopsis Genome1

The Arabidopsis Genome Sequencing Project was officially completed in late 2000, leading to the publication of a landmark paper describing, in broad outline, many salient features of the Arabidopsis genome ([Arabidopsis Genome Initiative [AGI], 2000][1]). However, the genome annotation, generated by
Direct adaptive control of faulty UAVs based on the paralleled integral and fuzzy control

In order to achieve the direct self-repairing control for faulty UAVs, a kind of direct adaptive control based on the paralleled integral and fuzzy control is proposed to the fault model of a UAV's flight control system. First, adopting the model reference adaptive control law based on fuzzy control, the control is realized by analyzing the flight control performance when some complex faults occur. Then, the method of a new direct self-repairing control is formulated by the paralleled integral and fuzzy control. Consequently, the stable error, the properties of response, and robustness are improved. The simulation results are given to illustrate that a good dynamic performance of the flight control system with large faults can be maintained with the proposed method.
Brain Regions Activated during an Auditory Discrimination Task in Insomniac Postmenopausal Patients before and after Hormone Replacement Therapy: Low-Resolution Brain Electromagnetic Tomography Applied to Event-Related Potentials

Electrical sources of auditory event-related potentials (ERPs) determined by means of low-resolution brain electromagnetic tomography (LORETA) in 48 unmedicated insomniac postmenopausal patients aged between 46 and 67 years were compared with those obtained in 48 age-matched normal female controls. Subsequently, the patients were included in a double-blind, placebo-controlled, comparative, randomized 3-arm trial phase – Climodien 2/3 [estradiol valerate (EV) 2 mg + the progestin dienogest 3 mg] was compared with EV 2 mg and placebo – followed by an open-label phase in which all of them received Climodien 2/2 (EV 2 mg + dienogest 2 mg). The double-blind and the open-label phase lasted 2 months. ERPs were recorded from 19 EEG leads in a two-tone oddball paradigm and electrical sources of standard N1 and P2 as well as target N2 and P300 components were estimated. In both patients and controls, LORETA revealed an activation of the superior temporal gyrus [auditory cortex, Brodmann areas (BA) 41, 42, 22] for all four components. For standard P2, an additional activation was observed medially parietally in the precuneus (BA 7, 5). For target N2, also a medial frontal source (BA 9, 10, 32) was identified. Finally, for the target P300 component – in addition to the aforementioned sources – activations in the prefrontal cortex (BA 9, 10, 46, 47), the inferior parietal cortex (supramarginal gyrus, BA 40, 39) and the posterior cingulum (BA 31) were found. Thus, patients and controls did not differ in the structural processes engaged in these fundamental aspects of information processing. However, patients demonstrated significantly reduced source strength – for standard ERP components predominantly in the temporal lobe and for target components predominantly in the frontal lobe, indicating reduced energetic resources available for perceptual and cognitive demands of the discrimination task. While, as compared with placebo, estrogen alone had only minor effects on ERP source strength, Climodien generally increased the impressed current density at the ERP peak latencies, predominantly in the temporal lobe, indicating an increased stimulus-induced cortical arousal in the primary and higher-order auditory cortex. Specifically, Climodien enhanced P300 source strength in the left middle temporal gyrus and in the left superior frontal gyrus, brain regions that on the one hand have been shown to be affected by hormone therapy in positron emission tomography and functional magnetic resonance neuroimaging studies and that on the other hand are among those critical for encoding and memory processes.
Extract segmentation lines of 3D model based on minima rule

This paper propose a novel algorithm pipeline to automatically extract the segmentation lines of 3D mesh accurately and efficiently. Our algorithm is based on the minima rule. The minima rule states that human perception usually divides a surface into parts along the concave discontinuity of the tangent plane. The algorithm pipeline has four steps. The first step is the estimate of discrete curvature . The extraction of concave regions of 3D mesh by discrete curvature is the second and critical step; the third step is the thinning algorithm which thin the concave region and eventually got the segmentation lines of 3D mesh; the last step is automatically form a closed loop based on the unclosed segmentation lines around the 3D model. In the end a series of experiments show its accuracy and efficiency.
Staircase Codes for High-Rate Wireless Transmission on Burst-Error Channels

We consider staircase codes, a class of high performance forward-error-correction codes for high-rate transmission, on channels with burst errors. Staircase codes with Reed-Solomon component codes and the baseline staircase code with binary Bose-Chaudhuri-Hochquenghem (BCH) component codes using block interleaving are implemented to combat burst errors. They are tested on burst-error channels with different burst lengths and bit-error probabilities. For both types of component codes, the software complexities and decoding latencies are compared to investigate, which codes have major impact on the decoding time of the staircase codes.
Public Support for Government Actions During a Flu Pandemic: Lessons Learned From a Statewide Survey

To better inform public health officials during a flu pandemic, this study analyzes a representative statewide telephone survey among 1,602 adults to examine knowledge and perceptions about a flu pandemic, trust in government, and support for government actions in a flu pandemic. The findings show citizens do not understand what avian/bird flu is and how it evolves into a pandemic. They also seem to have divergent perceptions regarding the susceptibility and severity of a flu pandemic. More than half of the respondents trust the government to handle a flu pandemic and show strong support for many proposed government actions in a pandemic, except for offering non—fully approved drugs. The findings suggest public health and risk communicators should reinforce support for controversial actions through trust building and personalization of risks rather than mere education or publicity. Public education and engagement should also begin pre-pandemic and continue throughout all phases of the event.

Rapid progression of NASH in childhood.

Nonalcoholic steatohepatitis (NASH) and nonalcoholic fatty liver disease (NAFLD) have been recognized entities in adult and pediatric medicine for more than 2 decades (1,2). Long-term follow-up studies of adults with NASH have confirmed that fibrosis can progress to cirrhosis (3). Individuals with NAFLD who have hepatic fibrosis and/or inflammation at presentation can progress to more severe fibrosis or cirrhosis and have a higher mortality when compared with individuals with steatosis alone (4–6). Nonalcoholic fatty liver disease is recognized as the most common cause of elevated liver enzymes in children. A recent autopsy series demonstrated that the estimated prevalence of NASH was 2.96% (22/742) in children. Furthermore, 23% of children with NAFLD in this study had NASH, whereas bridging fibrosis or cirrhosis was seen in 9% of children with NASH in this study (7). Long-term natural history data of pediatric NAFLD or NASH are not available. Certain components of routine laboratory tests may be predictive of NAFLD pattern and advanced fibrosis, but these serologic markers do not at present have adequate sensitivity or specificity to replace liver biopsy data to distinguish NASH from NAFLD (8). Serum alanine aminotransferase (ALT) and aspartate animotransferase (AST), for example, are not reliable measures of histological improvement in NASH (9). Thus, liver tissue histology becomes a critical requirement for accurate diagnosis and evaluation of fibrosis progression in patients with NAFLD or NASH. The invasive nature and inherent risk of percutaneous liver biopsy, coupled with the debatable benefit of liver biopsies in guiding therapy or changing clinical outcomes, have prevented gaining a full understanding of the natural history and progression rates of NASH in both children and adults. This report presents 2 children with NASH whose serial liver biopsies demonstrate progression of hepatic fibrosis in a short period of time. This report attempts to highlight that worsening of hepatic fibrosis can occur within childhood in patients with NASH.
Learning about Learning and Engineering: Engineers, Students, and Educa- tors Co-Design Challenges for a Science Center

We present two case studies of cross-community collaborations of museum educators, engineers from industry, and undergraduate engineering students tasked with co-designing engineering challenges for a science center’s drop-in engineering tinkering program. Each collaboration worked over a semester to research, brainstorm, design, develop, implement, and refine design challenges that represent authentic design practices of the collaboration’s industry engineers. The first collaboration involved engineering students from an education outreach club along with engineers from a software company, and the second collaboration involved engineering students from a product development course along with engineers from a sound reinforcement company. Qualitative methods were used to study the collaborations through preand post-surveys, observations via video-recording and field notes, and artifacts (e.g., notebooks, write-ups, and presentations). We find that the various members of the collaboration contributed in different ways to the design processes: the educators contributed educational accessibility and the industry engineers and engineering students contributed engineering authenticity, both shaping the criteria and ultimately the final design challenge. Using a human-centered design process and engagement with visitors at the science center, the multidisciplinary collaborators grew to appreciate co-design as a mutual learning experience involving interaction and contributions from the learners. This implies the importance of engaging curriculum designers with the learners in-situ. The student teams rated that, as a result, they had increased awareness of community needs and were able to make a difference as engineers. The student teams’ perceptions of engineering were reinforced, highlighting engineering as much more than a technical profession and stressing the accessibility and rewards of the engineering aspects of perseverence, curiosity, and creativity.

The main goal of this study is evaluating the feasibility of predicting the country, the age and the gender of a social network user, given his/her posts in one or several forums. The study was conducted with MySpace forums in Spanish language, aiming at classifying and extracting demographic information along with age and gender differences. The preliminary results presented and discussed here show some interesting conclusions about the possibility of inferring socio-demographic information from written material in the Web 2.0.
Efficient Estimation of Semiparametric Transformation Models for Two-Phase Cohort Studies

Under two-phase cohort designs, such as case–cohort and nested case–control sampling, information on observed event times, event indicators, and inexpensive covariates is collected in the first phase, and the first-phase information is used to select subjects for measurements of expensive covariates in the second phase; inexpensive covariates are also used in the data analysis to control for confounding and to evaluate interactions. This article provides efficient estimation of semiparametric transformation models for such designs, accommodating both discrete and continuous covariates, and allowing inexpensive and expensive covariates to be correlated. The estimation is based on the maximization of a modified nonparametric likelihood function through a generalization of the expectation–maximization algorithm. The resulting estimators are shown to be consistent, asymptotically normal and asymptotically efficient with easily estimated variances. Simulation studies demonstrate that the asymptotic approximations are accurate in practical situations. Empirical data from Wilms’ tumor studies and the Atherosclerosis Risk in Communities (ARIC) study are presented. Supplementary materials for this article are available online.
Cryopreservation of Xenopus transgenic lines

Xenopus laevis has been widely used for molecular, cellular, and developmental studies. With the development of the sperm‐mediated transgenic method, it is now possible to study gene function during vertebrate development by using this popular model. On the other hand, like other animal species, it is labor intensive, and the maintenance of transgenic lines is expensive. In this article, we investigated the possibility of using sperm‐cryopreservation as a means to preserve transgenic frog lines. We demonstrated that cryopreserved sperms are viable but not fertile under our in vitro fertilization (IVF) conditions. However, by microinjecting cryopreserved sperm nuclei, we successfully regenerated a transgenic line carrying a double promoter transgene construct, where the marker gene encoding the green fluorescent protein (GFP) is driven by the γ‐crystallin gene promoter and a gene of interest, encoding a fusion protein of GFP with the matrix metalloproteinase stromelysin‐3 (ST3‐GFP), is driven by a heat shock‐inducible promoter. We demonstrated the functional transmission of the ST3‐GFP transgene by analyzing the phenotype of the F1 animals after heat‐shock to induce its expression. Our method thus provides an inexpensive means to preserve transgenic frog lines and a convenient way for distribution of transgenic lines. Furthermore, the ease with which to microinject nuclei compared to the technically demanding transgenesis procedure with variable outcome should facilitate more laboratories to use transgenic Xenopus laevis for functional studies in vivo.

Examination of static and 50 Hz electric field effects on tissues by using a hybrid genetic algorithm and neural network

Abstract: The effects of electric fields on tissue are the main subject of many investigations. The importance of this subject comes from the electrical properties of the cell membrane and its sensitivity to changes in electrical conditions. Permeability of membranes to various ions can change by the effect of an electric field depending on their conductivity. The performances of cells and tissues change due to differences between the membrane's permeability to various ions and molecules. The aim of this study was to determine lipid peroxidation and superoxide dismutase (SOD) levels in spleen and testis tissues exposed to different intensities and exposure periods of static and 50 Hz alternating electric fields. The increase in SOD and thiobarbituric acid reactive substance levels of spleen and testis tissues was found to depend significantly on the type of electric field and the exposure period. The experimental results are applied to a hybrid genetic algorithm and neural network as learning data and the training of the feedforward neural network is realized. At the end of this training, without applying electric field to tissues, the determination of the effects of the electric field on tissues by using a computer is predicted by the neural network. After the experiments, the prediction of the hybrid genetic algorithm and neural network approach is on average 99.25%–99.99%.
Finite element modeling of radon distribution in natural soils of different geophysical regions

Abstract Radon migration from deep soil to the earth’s surface is investigated numerically using a developed Finite Element numerical model. The objectives of this study are: to predict the radon profile variation with the soil depth, the radon diffusion coefficients in multi-layer soils, the surface radon concentrations, and the soil–air radon fluxes. The flexibility of the Finite Element Method allows for accommodating varying diffusion coefficients in multi-layer soils and expressing convective-type boundary conditions. The convective-type boundary condition assumes that the surface radon flux is proportional to the difference between the radon concentration in the ambient air and the radon concentration at the soil surface. Radon concentration profiles with depth were collected from several geophysical locations such as Greece, Germany, South Africa, and Jordan. The numerical results show that the multi-layer profile of radon in natural soils is more descriptive than the one-layer one used traditionally, where each layer has its own diffusion coefficient. The effective diffusion coefficient, D, shows variation with the soil depth and its value differs from one geophysical location to another. A constant soil–air interface transfer coefficient is calculated and the soil–air radon flux is accordingly estimated. In addition, the surface radon concentrations at the soil–air interface are calculated from the model and compared against extrapolated field data.
Polarimetric weather radar simulator: Preliminary validation in rain case

One of the most important aspects regarding the design of a simulator is the validation of its outputs. This paper deals with the aspects connected to the validation of a weather polarimetric Doppler radar simulator through the analysis of the behavior of the polarimetric observables that it generates. Well established relationships commonly used in the meteorological community have been considered for the validation process, jointly with the way the microphysical parameters impact on reflectivity. Results show a good grade of reliability of the simulator in the realistic representation of the radar observations and its exploitability for further advancements in the sector.
