Designed and fabricated in 65nm CMOS, the transceiver achieves a 2.0-Gb/s data link with BER <; 10-9 while consuming a total power of 265mW.
Intestinal Parasitic Infection among Primary School Pupils in Osogbo Nigeria.

Parasitic infestation caused by intestinal parasites continues to take their roll on mankind. The symptoms commonly associated with parasitic infestation can be severe, acute or chronic. The prevalence of intestinal parasitic infestation was carried out over a period of three months ( January to March 2008) among 505 primary school children between 6-12 years of age in AUD Primary School A and B Sabo, St. Michael School A and B Ago-wande and L.A. Adenle Primary School Ayetoro in Olorunda Local Government with headquarter in Osogbo.Direct smear was used for analyzing faecalsamples for the parasites. Diagnosis was based on identification of the characteristic protozoan cysts and helminthes ova with a compound microscope. The prevalence for Ascarislumbricoides, Entamoebahistolytica,Hookworm, Trichuristrichuria were 68.9%, 8.3% and 5.5% respectively.Parasiticinfections between the male and female showed a significant different in both sexes ( P< 0.01). The percentage prevalence ofAscarislumbricoides was high in between 6-7years and ≥ 12 years. No specific age relationship was established for other intestinal parasites among the pupils. From the findings of this study, it is hereby recommended that deworming and health education should necessarily be a component of the primary health care programme with a focus on school children.This study showed low standard of sanitation among the pupils.
Repetition improves memory by strengthening existing traces: Evidence from paired-associate learning under midazolam

Here, we examined how repetition under midazolam, a benzodiazepine that prevents the storage of novel associations, affects cued-recall performance of paired-associates. We contrasted word pairs that were initially studied and tested repeatedly without any successful recall prior to the midazolam injection, with other pairs that were studied for the first time after the injection of midazolam. According to our SAC (Source of Activation Confusion) memory model, repetition leads to strengthening existing memory traces rather than creating multiple traces for each repetition. As such, it predicts that repetition under midazolam should benefit only pairs that were originally studied prior to the midazolam injection. This prediction was confirmed. The results suggest that memory traces for pairs studied prior to the midazolam injection were strengthened under midazolam. However, word pairs that had not been studied prior to the injection were not bound in long-term memory because midazolam prevents the formation of new associations.
Orthogonal frequency-division multiple access and its application to CATV networks

We introduce the concept of orthogonal frequency-division multiple access (OFDMA) and investigate its application to send upstream information from subscriber premises to the cable head-end in cable TV (CATV) networks. The carrier and timing synchronizations needed to ensure orthogonality between different subscriber signals are achieved by sending common pilot signals from the head-end. Whereas N demodulators are required to accommodate N simultaneous users in conventional FDMA systems, OFDMA only requires a single demodulator followed by an N-point discrete Fourier transform (DFT). We analyze the performance of this technique and compare it to time-division multiple access (TDMA) which appears in several international standards. Our results indicate that OFDMA is an attractive multiple access technique which offers increased robustness to narrowband interference, impulse noise, and other signal impairments which characterize typical CATV networks.
Nonsense-mediated decay as the molecular cause for autosomal recessive bestrophinopathy in two unrelated families.

PURPOSE To characterize the molecular basis of two novel BEST1 mutations causing autosomal recessive bestrophinopathy (ARB). Strong evidence argues in favor of the dominant negative effects of most autosomal dominantly inherited mutations, whereas there is only weak support for the molecular basis of the ARB phenotype. METHODS Patients underwent ophthalmic examination, color and autofluorescence fundus imaging, optical coherence tomography (OCT), electrooculogram, and full-field electroretinogram (ERG). BEST1 was directly screened for mutations in two ARB unrelated patients. The pathogenicity of the new BEST1 variants was assessed in silico and in vivo. RESULTS Two unrelated patients with diagnoses of ARB showed retinal pigment epithelial disturbances and abnormal ERGs. Each patient was homozygous for a novel BEST1 mutation, c. 521_522del and c.1100+1G>A. A carrier sibling (WT/c.521_522del) was unaffected. Both mutations generate a frameshift and a premature stop codon that, if translated, would seriously compromise bestrophin-1 function. However, the in vivo quantitative RT-PCR assays showed that most of the mutated transcripts were eliminated before translation because the mRNA-BEST1 levels were dramatically diminished the controls. CONCLUSIONS In truncating BEST1 mutations, the null phenotype associated with ARB is attributed to a substantial decrease of BEST1 expression promoted by the nonsense-mediated decay (NMD) surveillance mechanism. Moreover, the severity of the phenotype increases with the preserved amount of altered transcript, suggesting that the clinical outcome reflects the combined null and dominant negative effects of the two mutations over the patient's genetic background.
Staphylococcus aureus Cell Extract Transcription-Translation Assay: Firefly Luciferase Reporter System for Evaluating Protein Translation Inhibitors

ABSTRACT The promoter for the Staphylococcus aureus capsule polysaccharide synthesis gene (cap1A) was cloned in front of the firefly luciferase gene for use in a cell extractS. aureus transcription-translation system. The assay is rapid, reproducible, and sensitive and has a lower background level than the radiolabeled amino acid incorporation translation assays. We present data evaluating a transcription inhibitor and a number of protein translation inhibitors in this system.
Appropriate Patient Selection for Carotid Revascularization Procedures is Urgently Needed

The identification/selection of appropriate patient subgroups with asymptomatic carotid artery stenosis and the performance of prophylactic carotid endarterectomy (CEA)/carotid artery stenting (CAS) exclusively on these asymptomatic patient subgroups is currently one of the “hottest” topics in vascular surgery. It is now clear that offering CEA/CAS to asymptomatic carotid patients based only on the degree of carotid stenosis is unjustified and scientifically flawed. On the other hand, offering only best medical therapy to every asymptomatic patient, irrespective of certain high-risk criteria (such as the detection of microemboli by transcranial Doppler, intraplaque hemorrhage, silent embolic infarcts on brain computed tomography/magnetic resonance imaging, elevated biomarkers, family history), is equally wrong. The validation of specific measures to identify those asymptomatic patients at high risk for developing symptoms is crucial to achieve optimal use of carotid interventions and avoid wasting stroke prevention resources.
Wideband Microstrip Comb-Line Linear Array Antenna Using Stubbed-Element Technique for High Sidelobe Suppression

This paper presents a novel wideband microstrip comb-line linear array antenna using end feeding developed in the millimeter-wave. The proposed antenna is designed for 28 GHz and has 12 elements. The reflection-canceling slit structure technique is adopted to develop a broadside beam with low reflections at the input. The proposed array is designed using stub-studded radiating elements that create more resonances to broaden the impedance bandwidth. The structure is a novel comb-line linear array antenna with stub-studded radiating elements and was developed by applying stubs to eight of the radiating elements of the array to increase the input impedance bandwidth. This helps to attain a wideband linear array antenna on a single dielectric substrate, which conventionally has a narrow bandwidth. The input impedance bandwidth is from 23.5 to 33.11 GHz, which is equivalent to a bandwidth of 33.95%. The radiation pattern bandwidth is from 27.5 to 29.25 GHz for sidelobe levels of below −20 dB equivalent to a bandwidth of 6.167%. The proposed antenna array presents features such as a simple structure with low fabrication cost and an enhanced impedance bandwidth with high sidelobe suppression. The feasibility of the proposed antenna array was evaluated by simulation and measurement in the millimeter-wave band.
Contrast and Spatial Frequency Components in Visual Preferences of Newborns

A preferential-looking procedure was used to investigate newborns' responses to square-wave gratings varying in spatial frequency and contrast. A preliminary study confirmed that the gratings used in the experiment were suprathreshold. In the experiment newborns' preference for a grating of 0.1 cycle deg−1 within the peak contrast sensitivity range was examined. Reduction in the contrast of this grating led to a transfer of the preference to a high-contrast grating of the same space-averaged luminance with a spatial frequency outside this range (0.42 cycle deg−1). The findings are discussed with reference to the role of the contrast sensitivity function in pattern preferences of newborns: it is suggested that contrast and spatial frequency interact in determining pattern preferences.
Gender and ethnic differences in the control of hyperlipidaemia and other vascular risk factors: insights from the CEntralised Pan-South African survey on tHE Under-treatment of hypercholeSterolaemia (CEPHEUS SA) study

Aim The aim of the CEntralised Pan-South African survey on tHE Under-treatment of hypercholeSterolaemia (CEPHEUS SA) was to evaluate the current use and efficacy of lipid-lowering drugs (LLDs) in urban patients of different ethnicity with hyperlipidaemia, and to identify possible patient characteristics associated with failure to achieve low-density lipoprotein cholesterol (LDL-C) targets. There is little published data on LDL-C attainment from developing countries. Methods The survey was conducted in 69 study centres in South Africa and recruited consecutive patients who had been prescribed LLDs for at least three months with no dose adjustment for six weeks. All patients provided written consent. One visit was scheduled for data collection, including fasting lipid and glucose, and HbA1c levels. Results Of the 3 001 patients recruited, 2 996 were included in the final analyses; 1 385 subjects were of Caucasian origin (818 male), 510 of African ancestry (168 male), 481 of mixed ancestry (222 male) and 620 of Asian origin (364 male). Only 60.5% of patients on LLDs for at least three months achieved the LDL-C targets recommended by the NCEP ATP III/2004 updated NCEP ATP III guidelines and 52.3% the fourth JETF/South African guidelines. African females were on average younger than females of other ethnic origins, and had the lowest smoking rates but the highest prevalence of obesity, hypertension, the metabolic syndrome and diabetes mellitus (DM), with the worst glycaemic control. Although women were less likely than men to reach goal [OR 0.65 (CI 0.54–0.77), p < 0.001 for NCEP ATP III guidelines and OR 0.76 (CI 0.64–0.91), p < 0.003 for fourth JETF guidelines], women of African ancestry were just as likely not to reach goal as their Caucasian counterparts. Conclusion The results of this survey highlight the sub-optimal lipid control achieved in many South African patients, and profile important gender and ethnic differences. Control of cardiovascular disease risk factors across gender and ethnic groups remains poor.
Satellites of the Broucke-Hadjidemetriou-H\'{e}non family of periodic unequal-mass three-body orbits

The Broucke-Hadjidemetriou-Henon's (BHH) orbits are a family of periodic orbits of the three-body system with the simplest topological free group word $a$, while the BHH satellites have free group words $a^k$ ($k>1$), where $k$ is the topological exponent. Jankovic and Dmitrasinovic [Phy. Rev. Lett. 116, 064301 (2016)] reported 57 new BHH satellites with equal mass and found that at a fixed energy the relationship between the angular momentum ($L$) and the topologically rescaled period ($T/k$) is the same for both of the BHH orbits ($k=1$) and the BHH satellites ($k>1$). In this letter, we report 419,743 new BHH orbits ($k=1$) and 179,253 new BHH satellites ($k>1$) of the three-body system with unequal mass, which have never been reported, to the best of our knowledge. Among these newly-found 598,996 BBH orbits and satellites, about 33.5 % (i.e., 200,686) are linearly stable and thus many among them might be observed in practice. Besides, we discover that, for the three-body system with unequal mass at a fixed energy, relationship between the angular momentum ($L$) and topologically rescaled period ($T/k$) of the BHH satellites ($k>1$) is different from that of the BHH orbits ($k=1$).

Floating Solar Chimney versus Concrete Solar Chimney Power Plants

A solar chimney power plant has three major components: (1) A circular solar collector (Greenhouse) (2) A tall cylinder in the center of the solar collector ( Solar Chimney) (3) A set of air turbines geared to electric generators around the bottom of the solar chimney The air warms up inside the greenhouse by the solar irradiation and, due to its buoyancy, tends to escape through the Solar Chimney. This warm stream of air is leaving part of its thermodynamic energy to the air turbines placed in the path of the airflow. The solar chimney power stations were named Solar Aero-Electric Power Plants (SAEPPs) due to their similarity to Hydro Electric Power Plants. The efficiency of the SAEPPs is roughly proportional to the height of their solar chimneys. Solar Chimneys can be made as reinforced concrete structures (Concrete Solar Chimneys, CFCs), or as lighter than air inflated structures (Floating Solar Chimneys FSCs). These floating solar chimneys are made by successive balloon tubes, filled with a lighter than air gas. This permits to the FSCs to float in the air and thus to have heights 1.5divide3 Km giving to their SAEPPs higher efficiencies than Concrete Solar Chimney SAEPPs. Using ground thermal storage, or artificial thermal storage in the form of water in closed plastic tubes, it can be proved that the SAEPPs can operate 24 hours per day 365 days per year with a minimum guaranteed power production. This means that the SAEPPs, although renewable by nature, can have a similar operation to conventional power stations and thus can replace them. In the present paper a comparison for construction cost of SAEPPs with Floating Solar Chimneys and Concrete Solar Chimneys is given. It is shown that FSC Technology Power Plants is 5 to 6 times cheaper than CFC Technology Power Plants.
Extended Single Particle Model of Li-Ion Batteries Towards High Current Applications

Single particle models (SPM) are usually limited to low currents, which is a serious constrain for the usage of such models into vehicular battery management systems. The present study develops a physics-based ordinary differential equation (ODE) model, which is called extended single particle model (ESPM). In order to maintain the physical significance of the ODE model, a first-principle electrochemical partial differential equations (PDE) model is directly converted into an ODE model using volume-average method. The simulation results show that the ESPM model achieves an accuracy improvement of at least 14% when compared to the standard SPM for various levels of current inputs with only slight increase in computation time. The developed model paves the way for further improvements towards high-current, electrochemical ODE models with high physical significance and low computation burden.
PedStr Software for Cutting Large Pedigrees for Haplotyping, IBD Computation and Multipoint Linkage Analysis

We propose an automatic heuristic algorithm for splitting large pedigrees into fragments of no more than a user‐specified bit size. The algorithm specifically aims to split large pedigrees where many close relatives are genotyped and to produce a set of sub‐pedigrees for haplotype reconstruction, IBD computation or multipoint linkage analysis with the help of the Lander‐Green‐Kruglyak algorithm. We demonstrate that a set of overlapping pedigree fragments constructed with the help of our algorithm allows fast and effective haplotype reconstruction and detection of an allele's parental origin. Moreover, we compared pedigree fragments constructed with the help of our algorithm and existing programs PedCut and Jenti for multipoint linkage analysis. Our algorithm demonstrated significantly higher linkage power than the algorithm of Jenti and significantly shorter running time than the algorithm of PedCut. The software package PedStr implementing our algorithms is available at http://mga.bionet. nsc.ru/soft/index.html.
Cluster Governance and Institutional Dynamics A Comparative Analysis of French Regional Clusters of Innovation

Governance is an issue often neglected by studies on clusters even though recent empirical studies point out the potential role of cluster governance in the creation and integration of innovation networks within cluster. However, no insight is provided as to how, concretely, cluster governance manages to sustain innovation. Drawing on the concept of institutional work, we develop an integrative framework of institutional practices that cluster governance can implement to create a specific environment conducive to institutional dynamics and enhanced collaboration for innovation. Three levers – political, normative and cognitive – and 8 sets of institutional innovation practices are suggested. We apply this conceptual grid to the comparative analysis of three French clusters of innovation: one technopole and two competitiveness clusters. The findings show that 1) the three cluster governances activate all institutional levers but with a high variation of intensity, and 2) this intensity differences match the innovative performance of the clusters.
Efficient probabilistic reasoning in BNs with mutual exclusion and context‐specific independence

Prior work has shown that context‐specific independence (CSI) in Bayes networks can be exploited to speed up belief updating. We examine how networks with variables exhibiting mutual exclusion (e.g., “selector variables”), as well as CSI, can be efficiently updated. In particular, directed‐path singly connected and polytree networks that have an additional common selector variable can be updated in linear time (given null and general conjunctive evidence, respectively), where quadratic time would be needed without the mutual exclusion requirement. The above results have direct applications, as such network topologies can be used in predicting the ramifications of user selection in some multimedia data browsing systems. © 2004 Wiley Periodicals, Inc.

Placement of Piezoelectric Laminate Actuator for Active Structural Acoustic Control

The aim of this work is to investigate the problem of piezoelectric laminate placement. This problem is addressed in the case of modal identification and active control of plate like structures using piezoelectric laminates. The placement technique is based on the inspection of the controllability Grammian of the system expressed in a modal state-space coordinates. The controllability Grammian is able to quantify how structural modes are controllable with a set of predefined actuators. An initial finite element model or an experimental modal identification of the structure is required at the initial step. The procedure consists in making a selection of the smallest subset of actuators which gives a norm of the system transfer function as close as possible to the norm of the original full set. As the study context consists in noise reduction in buildings, the second part of this paper describes an application of this technique on a wooden shutter box in order to reduce the acoustic transmission towards the inner room.
Matlab tool for cardiovascular disease risk prediction

Several risk score tools are available in literature to predict the risk of death/myocardial infarction for coronary artery disease (CAD) patients, within a short period of time. However, these tools present some weaknesses. This work describes a Matlab tool implemented to address this problem. The physician can calculate the CVD risk of a patient as well as perform a set of configurations to adjust the parameters of the global model to a specific population. Therefore it can be a valuable framework in the decision support process. This software was validated through the combination of three well known current risk score tools (GRACE, TIMI, PURSUIT) applied to two real patient datasets (Santa Cruz hospital 460 patients; Leiria-Pombal hospital centre 99 patients).
Effects of limit feeding a high-grain diet on puberty and reproductive performance of ewes.

In Exp. 1, 39 ewe lambs (initial BW 29 +/- .1 kg) were used in a 2 x 2 factorial arrangement with two breeds (Polypay and Targhee) and two diets (high-forage and high-grain) to examine the effects of restricting intake of a high-grain diet on onset of puberty and lamb performance. The experimental diets were fed from 13 to 40 wk of age. The high-forage diet was composed of 80% alfalfa cubes and 20% supplement. The high-grain diet was 90% concentrate and 10% alfalfa cubes. Feed intake of the diets was controlled so that lambs fed the high-grain diet had the same growth rate as those fed the high-forage diet. Plasma insulin concentration was higher (P < .001) for lambs fed the high-grain diet than for those fed the high-forage diet. However, no diet effect on age at puberty was observed. In Exp. 2, 88 mature Targhee ewes were used to determine the effects of limiting intake of a high-grain diet on pregnancy and number of lambs born per ewe. Intake of the high-grain diet was restricted to achieve similar ME intake between diets. There were no diet effects on number of lambs born per ewe or subsequent lamb performance. Ewes fed the high-forage diet had a lower (P < .001) weight gain than those fed the high-grain diet. It was concluded that restricting intake of high-grain diets is an effective alternative to feeding high-forage diets for meeting the nutrient requirements of ewe lambs and gestating ewes; however, no improvements on reproductive performance were observed.
