Study on manoeuverability and control of an autonomous Wave Adaptive Modular Vessel (WAM-V) for ocean observation

In this paper, we are proposing the use of a catamaran equipped with standard navigational sensors as an autonomous surface vehicle for in situ measurement of oceanographic data or as a complimentary observing system. In this research, we mainly focus on the maneuverability of the Wave Adaptive Modular Vessel (WAM-V). The WAM-V must have ability to cruise on the water with a robust propulsion system which determines its propulsion capability and maneuverability. Firstly, the paper describes the configuration of WAM-V. Secondly the paper deals with mathematical modeling, which describes well physics based dynamics of WAM-V. Demand for WAM-V catamaran is justified to a point for improved manoeuverability and because the motion of the boat is affected by hydrodynamics, so many hydrodynamic parameters including resistance force for Mono hull and twin hull are estimated by towing tank experiment. It is observed from the experiments that at higher velocity (Froud Number (fn) > 0.3) due to interference between the two hulls the hydrodynamic derivatives do not remain same as in the case of a single hull. With the help of the geometrical shape of WAM-V the design ratios are calculated. The Matlab simulation is intended to analyze the different parameters for the effect of changing the propeller revolution which replaces the rudder action. Finally, the paper delineates the simulation results for PID tracking control of WAM-V using the Nomoto's response model.
Mn-rich tourmaline from Austria: structure, chemistry, optical spectra, and relations to synthetic solid solutions

Abstract Yellow-brown to pink Mn-rich tourmalines with MnO contents in the range 8-9 wt% MnO (~0.1 wt% FeO) from a recently discovered locality in Austria, near Eibenstein an der Thaya (Lower Austria), have been characterized by crystal structure determination, by chemical analyses (EMPA, SIMS), and by optical absorption spectroscopy. Qualitatively, the optical spectra show that Mn2+ is present in all regions of the crystals, and that there is more Mn3+ in the pink regions (~8% of the total Mn is Mn3+) than in the yellow-brown regions. A gamma-ray irradiated crystal fragment is distinctly pink compared to the yellow-brown color of the sample before irradiation, but it still has hints of the yellow-brown color, which suggests that the natural pink color in Mn-rich tourmaline from this locality is due to natural irradiation of the initial Mn2+. For these Mn-rich and Li-bearing olenite samples, crystal structure refinements in combination with the chemical analyses give the optimized formulae X(Na0.80Ca0.01◻0.19)Y(Al1.28Mn2+1.21Li0.37Fe2+0.02◻0.12) ZAl6T(Si5.80Al0.20)B3O27 [(OH)3.25F0. 43O0.32], with a = 15.9466(3) Å, c = 7.1384(3) Å, and R = 0.036 for the sample with ~9 wt% MnO, and X(Na0.77Ca0.03◻0.20)Y(Al1.23Mn2+1.14Li0.48Fe2+0.02Ti0.01◻0.12)ZAl6T(Si5.83Al0.17)B3O27 [(OH)3.33F0.48O0.19] for a sample with a = 15.941(1) Å, c = 7.136(1) Å, R = 0.025 and ~8 wt% MnO. The refinements show 1.22-1.25 Al at the Y site. As the Mn content increases, the Li and the F contents decrease. The Li content (0.37-0.48 apfu) is similar to, or lower than, the Li content of olenite (rim-composition) from the type locality, but these Mn-rich tourmalines do not contain [4]B. Like the tourmaline from Eibenstein an der Thaya, synthetic Mn-rich tourmaline (in a Li + Mn-bearing system), containing up to ~0.9 apfu Mn (~6.4 wt% MnO), is aluminous but not Li-rich. This study demonstrates that although a positive correlation exists between Mn and Li (elbaite) in tourmaline samples from some localities, this coupling is not required to promote compatibility of Mn in tourmaline. The a parameter in Mn-rich tourmalines (MnO: ≥3 wt%) is largely a function of the cation occupancy of the Y site (r2 = 0.97)
Efficacy trial of a DNA/rAd5 HIV-1 preventive vaccine.

BACKGROUND A safe and effective vaccine for the prevention of human immunodeficiency virus type 1 (HIV-1) infection is a global priority. We tested the efficacy of a DNA prime-recombinant adenovirus type 5 boost (DNA/rAd5) vaccine regimen in persons at increased risk for HIV-1 infection in the United States. METHODS At 21 sites, we randomly assigned 2504 men or transgender women who have sex with men to receive the DNA/rAd5 vaccine (1253 participants) or placebo (1251 participants). We assessed HIV-1 acquisition from week 28 through month 24 (termed week 28+ infection), viral-load set point (mean plasma HIV-1 RNA level 10 to 20 weeks after diagnosis), and safety. The 6-plasmid DNA vaccine (expressing clade B Gag, Pol, and Nef and Env proteins from clades A, B, and C) was administered at weeks 0, 4, and 8. The rAd5 vector boost (expressing clade B Gag-Pol fusion protein and Env glycoproteins from clades A, B, and C) was administered at week 24. RESULTS In April 2013, the data and safety monitoring board recommended halting vaccinations for lack of efficacy. The primary analysis showed that week 28+ infection had been diagnosed in 27 participants in the vaccine group and 21 in the placebo group (vaccine efficacy, -25.0%; 95% confidence interval, -121.2 to 29.3; P=0.44), with mean viral-load set points of 4.46 and 4.47 HIV-1 RNA log10 copies per milliliter, respectively. Analysis of all infections during the study period (41 in the vaccine group and 31 in the placebo group) also showed lack of vaccine efficacy (P=0.28). The vaccine regimen had an acceptable side-effect profile. CONCLUSIONS The DNA/rAd5 vaccine regimen did not reduce either the rate of HIV-1 acquisition or the viral-load set point in the population studied.

A combined method for anti-islanding in PV inverters

This paper presents a combined method to detect islanding conditions. The method combines two approaches in a two stage process, and is based on the injection of reactive current as a disturbance to detect islanding. In the first stage, the method tests the voltage rate of change and the frequency rate of change. Once an islanding situation is presumed in the first stage, then in the second stage, a positive feedback scheme is enabled to confirm the islanding condition. This combined detection method is more effective and precise, avoids false tripping out by reducing the sensitivity to other perturbations, and avoids instabilities as the positive feedback is not connected all time. Simulations are presented to assess the performance of the proposed combined detection method.
Painful genital ulcers.

colleague came into the charting area and said he thought he had just seen his first case of chancroid. He asked me if I had a moment to see the patient, a 32-year-old African American man who noted the onset of painful sores on his penis 1 week ago. The patient consented to a second opinion. On further questioning, he remembered a tingling pain that started a few days prior to the sores. When asked about any previous outbreaks, he thought he may have had something like this 1 year ago. He did not remember seeing blisters before the sores appeared. The last time the patient had sexual relations was 2 months ago, with someone he met at a party. He claimed he used a condom. He did not have any lesions at that time and had never had a sexually transmitted disease before.
Modification of dose distribution in high-energy electron beam treatment.

A method to modify the dose distribution of high-energy electron beams of betatrons operating in the 4- to 31-MeV energy range was successfully applied to cases of carcinoma of the buccal mucosa, using 10- to 16-MeV energy. Marked radiation reaction occurred only in the area of the lesion. No visible reaction was seen in other parts of the oral cavity. Two of 3 lesions improved and showed no evidence of disease one and one-half years after completion of treatment.
Recent Trends in Emerging Technologies toward 5 G Networks

Considering current trends, the need for more sophisticated bandwidth-intensive services will further push the limits on future standards to provide integration between wireless technologies and higher speeds, requiring a new generation of mobile networks, the so-called fifth generation (5G). Advanced technologies such as massive MIMO and millimeter-wave systems will have significant impact on design of cellular architecture. Among the new features foreseen by 5G networks, device to device communication may have a prominent role. This paper seeks to provide a comprehensive survey of flagship research trends in the domain of emerging 5G technologies. Key-Words: 5G architecture, D2D communications, massive MIMO, mmWave, network densification.
Hybrid Low-Grade Geothermal-Biomass Systems for Direct-Use and Co-Generation : from Campus Demonstration to Nationwide Energy Player

The Climate Action Plan (CAP) at Cornell University in Ithaca, New York, USA proposes a set of actions to achieve a carbon-neutral campus by 2050 or sooner. These actions include energy conservation initiatives, upgrading the campus heat distribution system, as well as developing renewable and sustainable heat and electricity production from geothermal, biomass, wind, and solar resources at a scale to serve its campus of over 30,000 students, faculty and staff. The CAP envisions a hybrid co-generation system using an Enhanced Geothermal System (EGS) and biomass that could supply nearly 100% of the campus heating demand, a small fraction of the electricity demand, and cuts CO2 emissions by more than 40%. In this paper, the GEOPHIRES software was used to simulate a low-grade EGS site in Ithaca, although still with geothermal gradients above average for the Northeast, and was applied in combination with published regional data on biomass cultivation and gasification to explore the technical and economic potential of a hybridized geothermalbiomass system. With base case assumptions without any subsidies or incentives, an initial capital investment of $217M resulted in a levelized cost of heat (LCOH) of 15.9 $/MMBtu (5.4 ¢/kWhth). This system would provide 98% of the campus heating demand, 7% of the electricity demand, and would cut CO2 emissions by 94,000 metric tons (43%). Further, with the Cornell campus geothermalbiomass system serving as a community-scale demonstration plant, the potential of hybrid geothermal-biomass systems as major energy suppliers for heat and electricity on a regional and nationwide scale is considered in this study.
Morphometry as a Method of Studying Adaptive Regulation of Embryogenesis in Polluted Environments

Amphibiansone of the most convenient natural objects to study the effect of various pollutants (Dawson et al, 1985). They are very sensitive to changes in the environment. Larval and adult specimens have a high permeable skin and their life cycle takes place in water and in terrestrial ecosystems, depending on the stage of the life cycle; they have different types of food; their special reproduction allows monitoring of development and the quantity to conduct representative research (Cooke, 1974; Greenhouse, 1976; Sparling et al, 2001).
Outbreak of Poliomyelitis in Hispaniola Associated with Circulating Type 1 Vaccine-Derived Poliovirus

An outbreak of paralytic poliomyelitis occurred in the Dominican Republic (13 confirmed cases) and Haiti (8 confirmed cases, including 2 fatal cases) during 2000–2001. All but one of the patients were either unvaccinated or incompletely vaccinated children, and cases occurred in communities with very low (7 to 40%) rates of coverage with oral poliovirus vaccine (OPV). The outbreak was associated with the circulation of a derivative of the type 1 OPV strain, probably originating from a single OPV dose given in 1998–1999. The vaccine-derived poliovirus associated with the outbreak had biological properties indistinguishable from those of wild poliovirus.
HSP induction mediates selective clearance of tau phosphorylated at proline‐directed Ser/Thr sites but not KXGS (MARK) sites

Neurofibrillary tangles (NFTs) are a characteristic neuropathological feature of Alzheimer's disease (AD), and molecular chaperones appear to be involved in the removal of disease‐associated hyperphosphorylated tau, a primary component of NFTs. Here, novel HSP90 inhibitors were used to examine the impact of chaperone elevation on clearance of different tau species in transfected cells using a unique quantitative assay. The HSP90 inhibitors reduced levels of tau phosphorylated at proline‐directed Ser/Thr sites (pS202/T205, pS396/S404) and conformationally altered (MC‐1) tau species, an epitope that is immeasurable by standard Western blot techniques. The selective clearance of these phospho‐tau species and MC‐1 tau was mediated via the proteasome, while lysosomal‐mediated tau degradation seems to lack specificity for certain tau species, suggesting a more general role in total tau removal. Interestingly, tau phosphorylated at S262/S356 within the tau microtubule binding domain was minimally affected by chaperone induction. Overall, our data show that chaperone induction results in the selective clearance of specific phospho‐tau and conformationally altered tau species mediated by the proteasome; however, the apparent stability of pS262/S356 tau may also explain why MARK is able to regulate normal tau function yet still be linked to the initiation of pathogenic tau hyperphosphorylation in AD.
Classification and feature extraction of binucleate cells using Mahalanobis distance and Gabor wavelet analysis

A hybrid methodology of feature extraction and classification is proposed in this paper to classify binucleate and non-binucleate or normal cells. The proposed methodology consists of a Gabor filter-based feature extraction using two types of Gabor filters, namely circular Gabor and Gabor wavelet. Feature matrix considering mean and variance are calculated in sets of 50 for each of the filters. Thereafter, dimensionality reduction is done using a binary particle swarm optimisation (BPSO) technique to screen out the redundant features. Finally, Mahalanobis distance (MD) is used to classify the images into respective classes using the reduced set of features. To show the efficacy and robustness of the proposed hybrid technique using Gabor wavelets, the classification accuracy is calculated and compared with circular Gabor.
Automated Real Time Emotion Recognition Using Facial Expression Analysis

The focus of this study is on computer automated perception of human emotion. We explore the use of Fisherfaces for the recognition of human emotion in facial images. We train a multitude of Fisherface models and evaluate their performance against an independent test set. We build and test a compound hierarchical system that attempts to interpret human emotion in real time using face detection and tracking algorithms in conjunction with our facial expression analysis methodology. Our results indicate that Fisherfaces can be useful in predicting emotion based on content retrieved from facial images. We note that, with this approach, some emotions are more easily predicted than others. We also suggest that a compound hierarchical model is more effective than a single stand-alone Fisherface model.

A compact microstrip patch antenna with circular snipped slot for GSM, Wi-Fi and WiMAX applications

A rectangular microstrip patch antenna with probe feed is proposed in this paper. The patch of an antenna has a key circular slot which is auxiliary truncated in circular style resulting three narrow bands of the most worthy and in-use wireless technologies of the modern age, that are GSM, Wi-Fi and WiMAX. The resonating bandwidths of the presented antenna ranges from 1.79 to 1.83 GHz for GSM 1800, 2.40 to 2.48 GHz for Wi-Fi and from 3.32 to 3.42 GHz used for WiMAX. The design process has been carried out in HFSS (High Frequency Structure Simulator) and antenna is fabricated manually, to assess and evaluate the real characteristics.
Integrating smoking cessation into routine public prenatal care: the Smoking Cessation in Pregnancy project.

OBJECTIVES In 1986, the state health departments of Colorado, Maryland, and Missouri conducted a federally-funded demonstration project to increase smoking cessation among pregnant women receiving prenatal care and services from the Women, Infants, and Children (WIC) program in public clinics. METHODS Low-intensity interventions were designed to be integrated into routine prenatal care. Clinics were randomly assigned to intervention or control status; pregnant smokers filled out questionnaires and gave urine specimens at enrollment, in the eighth month of pregnancy, and postpartum. Urine cotinine concentrations were determined at CDC by enzyme-linked immunosorbent assay and were used to verify self-reported smoking status. RESULTS At the eighth month of pregnancy, self-reported quitting was higher for intervention clinics than control clinics in all three states. However, the cotinine-verified quit rates were not significantly different. CONCLUSIONS Biochemical verification of self-reported quitting is essential to the evaluation of smoking cessation interventions. Achieving changes in smoking behavior in pregnant women with low-intensity interventions is difficult.
A radar target for calibration and for codes validation

The electromagnetic scattering of a plane wave by a penetrable (e.g., dielectric) or impenetrable (e.g., metallic) sphere concentric with a thin metallic disk is considered, in the frequency domain. At low and intermediate frequencies, either separation of variables and mode matching with matrix truncation or a direct numerical approach such as the MoM is adopted, while at high frequencies a combination of GTD and physical optics is employed. The analytical and numerical results are compared to measurements made in an anechoic chamber.
Remifentanil With Thiopental for Tracheal Intubation Without Muscle Relaxants

Tracheal intubation may be accomplished with remifentanil and a non-opioid IV anesthetic without a muscle relaxant. In this study, we evaluated in double-blinded, prospective, randomized manner the dose requirements for remifentanil with thiopental without muscle relaxant administration to obtain clinically acceptable intubation conditions and cardiovascular responses. After premedication with midazolam 0.03 mg/kg IV, 105 patients were randomized equally to one of three study groups, each receiving the following: remifentanil 2 &mgr;g/kg (Group I), 3 &mgr;g/kg (Group II), and 4 &mgr;g/kg (Group III). Remifentanil was administered over 30 s, and anesthesia was induced with thiopental 5 mg/kg. Tracheal intubation conditions were assessed by the anesthesiologist performing the intubation as: (a) excellent, (b) satisfactory, (c) fair, and (d) unsatisfactory. There were no statistically significant differences among groups regarding to demographic data. Blood pressure and heart rate did not increase in any group after accomplishing intubation. There was a significant improvement in intubation conditions between Groups I and II, I and III, and II and III (P < 0.001). We conclude that remifentanil 4 &mgr;g/kg administered before thiopental 5 mg/kg provided excellent or satisfactory intubation conditions in 94% of patients and prevented cardiovascular responses to intubation.
Halogen bonding (X‐bonding): A biological perspective

The concept of the halogen bond (or X‐bond) has become recognized as contributing significantly to the specificity in recognition of a large class of halogenated compounds. The interaction is most easily understood as primarily an electrostatically driven molecular interaction, where an electropositive crown, or σ‐hole, serves as a Lewis acid to attract a variety of electron‐rich Lewis bases, in analogous fashion to a classic hydrogen bonding (H‐bond) interaction. We present here a broad overview of X‐bonds from the perspective of a biologist who may not be familiar with this recently rediscovered class of interactions and, consequently, may be interested in how they can be applied as a highly directional and specific component of the molecular toolbox. This overview includes a discussion for where X‐bonds are found in biomolecular structures, and how their structure–energy relationships are studied experimentally and modeled computationally. In total, our understanding of these basic concepts will allow X‐bonds to be incorporated into strategies for the rational design of new halogenated inhibitors against biomolecular targets or toward molecular engineering of new biological‐based materials.
Service class mapping based on integer programming algorithm in the third party agent

In this paper, we propose a novel approach to inter-provider service class mapping in third party (3P) negotiation model. The foundation for this mapping is laid on integer programming model enabling service class selection in domains on the end-to-end path so that performance requirements in terms of quality of service (QoS) parameters are fulfilled. This selection is based on two constraints, referring to performance fulfillment and minimal interconnection costs. Proposed approach is suitable for class mapping in inter-provider scenarios when service negotiation is deployed over 3P agent.
Pseudopapilledema of juvenile diabetes mellitus.

Optic disc edema with neovascularization, peripapillary hemorrhages, and exudates mimicking true papilledema occurred in three teen-aged patients with long-standing juvenile diabetes mellitus controlled by insulin. Despite the appearance of papilledema, the unusual signs, symptoms, and course of this syndrome suggest that it is an ischemic manifestation of diabetic microangiopathy within the optic papilla in the absence of adequate collateral circulation. This report confirms the existence of a diabetic optic neuropathy, and discusses its vascular pathogenesis and management.
