PTS Technique for MIMO-OFDM Paper Reduction

— Non linearity of High Power Amplifier will increase the bit error rate and hence it is necessary to perform back off from nonlinear region to linear region OFDM technology is widely used in current 4G standard. While Performing IFFT there is a possibility that some signals may be added with same phase and hence increasing peak power of signal which cease to increase peak to average power ratio (PAPR). MIMO-OFDM technology uses multiple transmitter and multiple receiver in combination to OFDM technology which leads to same problem of PAPR on different paths from multiple transmitter to multiple receiver. In this paper we discussed PTS technique for PAPR reduction OFDM technology, simulation of theoretical Complementary Cumulative Distributive Function (CCDF) of MIMO-OFDM technology is given in paper
Intellectual and Social Capitals Development A Case in Malaysian ’ s ICT Companies

Intellectual capital is said to be a source of competitive advantage and there is evidence that business success can be partly explained by its intellectual capital. It is argued that the main dimensions of social capital of relevance to intellectual capital are structural, cognitive, and relational capitals because these, among other things, foster the exchange of knowledge and resources among the organization members. The objective of this paper is to investigate the importance of social capital in fostering the development of intellectual capital among the engineers. This study used case study method and data were collected through interviews. Data were analysed using within-case and cross-case analysis. The analysis shows that the most important dimension for intellectual capital development is structural capital. The findings also suggest that structural capital is a prerequisite of relational capital among engineers in an organizational project. The findings also demonstrate that frequent meetings and interactions, relationship, hierarchy or status, and shared language are among the factors that foster the sharing of knowledge among engineers. This study also elucidated that structural and relational capitals play important role in knowledge sharing and hence intellectual capital development.
The Burden of the Draft: The Vietnam Years

This study explores the draft during the Vietnam era. Using a natronal longitudinal sample of young men who were draft vulnerable over the period, it estimates rhe likelihood of being drafted for whites and blacks. Unlike other studies, it uses pre-service traits in the analysis. The burden of the draft did not fall evenly upon young men ojtheperiod. Individuals who unfortunately possessed combinations of draft vulnerable personal characteristics-fsr example, black high school graduates-paid a higher than avergge price. The strength of the draft pressure variable, however, demonstrates the overriding importance of military demand. Men who were draft eligible during periods of high draft calls were least able to use the many deferment avenues. Hence, the fortunes of war or the luck of the draw was an important f~ctor In determining who was drafted. The spectre of the draft once again hangs over young men 19 and 20 years of age. Indeed, with the advent of draft registration in the summer (of 1980, the possibility of a return to conscription seems closer than at any time in the last 8 years. Not since the Selective Service System was dismantled and the All Volunteer Forces (AVF) established has the issue of conscription been so debated. President Carter raspanded to the Afghanistan Crisis by renewing draft registration. After heated debate, Congress agreed to fund registration for men only. Debate over the draf is not new. During the late 15160's, social scientists joined other groups advocating an end lo the draft. The political decision to end the draft was based in part upon the analysis of social scientists. This paper reviews the equity arg~tments surroundir~g conscripti~~n. In addition, the likelihood of a yaeang man being drafted is empir~cally tested. The results of this study should provide new insight lox the current debate. CONS@RI[PTkOPd AND THE BABY BOOM Young rnen of the Vietnam era were born and reached maturity during a period characterized by ini-ernational crisis (WW 11, Korea, Berlin, Cuba). The
Description of new species of Pterygorhabditis Timm, 1957 and Aspidonema (Sachs, 1949) Andrássy, 1958 (Nematoda: Bunonematoidea) in aquatic habitats from India

Abstract The paper contains descriptions of two new species of the genera Pterygorhabditis Timm, 1957 and Aspidonema (Sachs, 1949) Andrássy, 1958 belonging to the families Pterygorhabditidae Goodey 1963 and Bunonematidae Micoletzky 1922, respectively. Species were procured from fixed samples, collected earlier from aquatic habitats. Pterygorhabditis punctata n. sp. is characterized by a cuticle with flattened hexagonal blocks arranged in eight longitudinal rows in both sexes; each metastegostomal plate with a minute denticle, and males with long, slender, fused spicules and nine pairs of post-cloacal, prominently setose genital papillae. Aspidonema formosa n. sp. is the first report of the genus from India. The species is characterized by the right side provided with 35–48 pairs of warts flanking a row of smooth membranous shields and surrounded by a well-developed network and an anisomorphic metastegostom without discernible armature. Species are compared with other congeners, together with the diagnoses of amended genera, and keys to the identification of species are provided.
Non-invasive Glaucoma Screening Using Ocular Thermal Image Classification

Ocular thermography is an important, emerging modality in the diagnosis and management of diseases related to eye. It is a non-invasive procedure to evaluate the presence of eye diseases and monitor the response to treatments. In this paper, we propose and evaluate a system designed using infrared thermal image processing that detects glaucoma. Euclidean distance based segmentation technique is used to threshold the IR image to obtain the region of interest, where the manifestation of glaucoma is predominant. Features are extracted using statistical moments from the temperature mapped IR image and Gray Level Co-Occurrence Matrix of the IR image. Two significant attributes, namely the homogeneity and area of region of interest are the inputs to a Support Vector Machine classifier to classify a given input ocular thermal image as a normal or diseased image. In our simulation study, one hundred ocular thermal images with even number of normal and diseased subjects were analysed. The classifier has achieved a maximum accuracy of 96% when homogeneity and area of region of interest are used as attributes, indicating the potential use of proposed method for screening patients even at early stages of glaucoma.
Barriers to Follow-up for Women with a History of Gestational Diabetes

Women with gestational diabetes (GDM) are at increased risk for type 2 diabetes (T2DM), but many do not receive recommended follow-up. We sought to identify barriers to follow-up screening. We surveyed primary care providers (PCPs) and obstetric and gynecology care providers (OBCPs) in a large health system. We also assessed documentation of GDM history in the health care system's electronic medical record. Four hundred seventy-eight clinicians were surveyed, among whom 207 responded. Most participants (81.1%) gave an accurate estimate of risk of progression to T2DM. PCPs were less likely than OBCPs to ask patients about history of GDM (odds ratio [OR] 0.43, 95% confidence interval [CI] 0.20 to 0.90), but they were far more likely to indicate that they order glucose screening for women with a known history (OR 4.31, 95% CI 2.01 to 9.26). Providers identified poor communication between OBCPs and PCPs as a major barrier to screening. Fewer than half (45.8%) of 450 women with GDM by glucose tolerance test criteria had that history documented on their electronic problem list. Clinicians are aware that women with GDM are at high risk of developing type 2 diabetes, but they do not routinely assess and screen patients, and communication between OBCPs and PCPs can be improved.
IMPROVED INJECTION MOLDING OF ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE USING SUPERCRITICAL NITROGEN

Ultra-high molecular weight polyethylene (UHMWPE) was injection molded using a microcellular injection molding (MIM) process to introduce supercritical nitrogen (SC-N2) into the melt to decrease the viscosity of the polymer and improve processability while reducing degradation. Solid and foamed parts were produced. Rheological tests indicated that a viscosity reduction during processing decreased the material’s tendency to degrade during injection molding. Although the SC-N2 processing did not improve the tensile strength of the molded parts, it significantly improved the processability of UHMW-PE via injection molding. Micro-computed tomography (μCT) images illustrated the internal structures of the parts and revealed sink marks in the solid formed SC-N2 processed samples, even when packing pressure was applied.
Image Mosaic

We employ Convolutional Neural Networks with the VGG16 and VGG19 architecture to classify photographs that span four decades of professional photographic work by Mário Cabrita Gil. For each photograph, the 4096 dimension feature vector is reduced to two-dimensions by employing distributed Stochast Neighbor Embedding (t-SNE). Finally, the photographs are arranged according to their similarity value in a mosaic display.
Small cell carcinoma of the cervix: a clinicopathologic and immunohistochemical study of 23 cases.

Twenty-three patients with primary small cell carcinoma of the uterine cervix are presented. Their ages ranged between 23 and 63 years (average, 43 years). Blood spotting or vaginal bleeding was the most common clinical presentation. Histologically, the tumors were densely cellular and showed trabecular nesting or a sheet-like pattern. The neoplastic cells had scant cytoplasm, round nuclei, absence of nucleoli, and finely dispersed chromatin. Nuclear molding, single cell necrosis, and high mitotic activity were found in all tumors. There was a minor component of large cell neuroendocrine carcinoma in three cases, while foci of adenocarcinoma were identified in two cases. Immunohistochemical studies were performed in all 23 tumors which showed immunoreactivity for cytokeratin. Ten small cell carcinomas were immunoreactive for chromogranin, 13 for synaptophysin, and 10 expressed p53 protein. Treatment modalities included hysterectomy alone or combined with chemotherapy and/or radiation therapy. A few patients received chemotherapy and/or radiation alone. Follow-up information was obtained in 22 cases; 15 patients died of tumor between 6 and 43 months, while seven patients have remained alive 12 to 273 months. One patient was lost to follow-up. Small cell carcinoma of the cervix is a highly aggressive neoplasm. However, early diagnosis and combined therapeutic modalities may lead to longer survival in some patients. Although the use of immunohistochemistry may be helpful in the diagnosis, small cell carcinoma still remains a morphologic diagnosis.
[Quality of clinical trials published in Spain on asthma in comparison to trials in English language journals].

OBJECTIVES To evaluate the quality of clinical trials on asthma published in Spanish journals in comparison with those published in European or North American English-language journals. METHOD Clinical trials were identified by searching MEDLINE and the Spanish Medical Index (Indice Médico Español), and by manual searches for trials mentioned in the bibliographies of the previously identified trials. Quality was assessed by the method proposed by Detsky and colleagues in their 1992 article in Journal of Clinical Epidemiology. RESULTS The articles published in Spanish journals had lower mean quality scores than those in European or North American English-language journals. Trials published in Spain were less likely to give certain details of methodology, including ethics committee approval, details of randomization or patient enrollment and blinding. Among trials published in Spain, those with non-Spanish authors had lower mean quality scores. CONCLUSION Clinical trials published in Spain on asthma treatments are of poorer quality than those published in English-language journals. Editors should consider using clinical trial quality checklists during the peer review process to raise the standards for published articles.
Effect of flaxseed on blood lipid level in hyperlipidemic patients.

INTRODUCTION Hyperlipidemia is one of the most important risk factors of ischemic heart disease. Previous studies showed that flaxseed has the potential to improve lipid profiles. In this study we investigated the effects of flaxseed powder intake on lipid profiles of patients with hyperlipidemia. MATERIALS AND METHODS This study was a randomized controlled clinical trial. Seventy patients with hyperlipidemia participated in the research. After detailed diet and lifestyle education, blood samples were collected from the participants. Patients with hyperlipidemia were randomly divided in to two intervention and control groups. The intervention group received 30 g of raw flaxseed powder every day for 40 days. Serum lipids were measured again in two groups after that time. Activity and food intakes of two groups were recorded. RESULTS In the intervention group, weight and body mass index were considerably reduced. Total cholesterol was reduced in the intervention group and increased in the control group, both of which were significant. Low density lipoprotein significantly increased in the control group and reduced in intervention group; also, triglyceride was increased in the control group and reduced in the intervention group, which were significant Table 1. CONCLUSION Based on the findings obtained in this research, flaxseed powder intake desirably reduced serum lipids. The differences between two groups on the basis of analysis of covariance test were significant. In all cases except for the HDL-c, this is an effective intervention. Therefore, flaxseed may be regarded as a useful therapeutic food for reducing hyperlipidemia.
Methodology for quantitative determination of the carbohydrate composition of brown seaweeds (Laminariaceae)

The monosaccharide composition of four different samples of brown seaweeds Laminaria digitata and Saccharina latissima were compared by different high performance anion exchange chromatography (HPAEC) methods after different acid hydrolysis treatments or a cellulase treatment. A two-step treatment of 72% (w/w) H2SO4 + 4% (w/w) H2SO4 performed best, but cellulase treatment released more glucose than acid treatments. HPAEC with pulsed amperometric detection (PAD) allowed quantification of all present neutral sugars and the sugar alcohol mannitol. Furthermore, the use of guluronic, glucuronic, and galacturonic acid as standards enabled quantification of the uronic acids. A complete map of amino acids, fatty compounds, minerals, and ash was also achieved. L. digitata and S. latissima harvested in Denmark April (Baltic Sea, 2012) were dominated by alginic acid and ash (each ∼30% by weight (w/w) of the dry matter) and 10% (w/w) protein. In contrast, the dominant compound of L. digitata harvested in August (North Sea, 2012) was glucose constituting 51% w/w of the dry matter, and with 16% w/w alginic acid. Washing prior to analysis mainly removed salts.
Ames Waltzer deaf mice have reduced electroretinogram amplitudes and complex alternative splicing of Pcdh15 transcripts.

PURPOSE Mutations of PCDH15, the gene encoding protocadherin 15, cause either nonsyndromic deafness DFNB23 or Usher syndrome type 1F (USH1F) in humans and deafness with balance problems in Ames waltzer (av) mice. Persons with USH1 usually begin to exhibit signs of retinitis pigmentosa (RP) in early adolescence, but av mice are reported to have functional retinas. In this study, the auditory, visual and molecular biological phenotype of Pcdh15av-5J and Pcdh15av-Jfb mice is characterized, and their usefulness as animal models of USH1 is evaluated. METHODS Hearing thresholds of mice between 6 and 10 weeks of age were measured by auditory brain stem response (ABR). Immunohistochemistry and histology were used to examine the effect of homozygosity of Pcdh15av-5J on stereocilia bundles of inner ear hair cells and on the photoreceptor cells of the retina. Scotopic and photopic Ganzfeld ERGs were recorded from homozygous Pcdh15av-5J and Pcdh15av-Jfb mice at different ages. Heterozygous littermates served as control subjects. Measurements of the width of the outer nuclear layer (ONL) and the length of rod photoreceptor outer segment (ROS) were made. RESULTS Homozygous Pcdh15av-5J mice have profound hearing loss and disorganized stereocilia bundles of inner ear hair cells. Compared with heterozygous littermates, homozygous Pcdh15av-5J and Pcdh15av-Jfb mutant mice had scotopic ERG amplitudes consistently reduced by approximately 40% at all light intensities. The b-to-a-wave ratio confirmed that the a- and b-waves were reduced proportionally in homozygous mutant mice. Histologic measurements of retinal sections revealed no significant differences in either the ONL width or the ROS length as a function of genotype. The protocadherin 15 labeling pattern with antisera PB303 in the retina of both heterozygous and homozygous Pcdh15av-5J mice was indistinguishable from the wild type. Wild-type Pcdh15 have many alternatively spliced isoforms. A novel isoform was found in the retina of homozygous Pcdh15av-5J mice, which appears to circumvent the effect of the mutant allele (IVS14-2A-->G), which causes skipping of exon 14, a shift in the translation reading frame and a premature stop codon in exon 15. CONCLUSIONS Pcdh15(av-5J) and Pcdh15(av-Jfb) mice do not faithfully mimic the RP found in USH1 due to mutations of PCDH15, but have significantly attenuated ERG function in the absence of histologic change. The decline in ERG amplitude with a preserved b-to-a-wave ratio suggests a role for Pcdh15 in retinal function and/or generation of the ERG potentials. Understanding the molecular mechanism by which av mice circumvent degeneration of the retina might offer insights into potential therapies for USH1.
GEOMETRICAL SOLUTIONS OF HAMILTON-JACOBI EQUATIONS

The concept of the geometrical solution of Hamilton-Jacobi equations in arbitrary space dimension is introduced. The characterization of such solution is based on the intersection of several invariant hyper-surfaces in the space of 1-jets. This solution notion allows not only for the smooth evolution beyond the usual singularity formation but also for superposition of underlying geometrical solutions. The need to consider such solutions occurs, for example, when the underlying Hamilton-Jacobi equation arises in the high frequency wave approximation problems. Classical characteristic analysis is limited to the local considerations owing to the crossing of characteristics. The notion of the classical viscosity solution leads to the global well-posedness, but excludes possible multi-valued solutions. The notion of the geometrical solution advocated here serves as an intrinsic identification for possible multivalued solutions. The geometrical solution is first described for general first-order PDEs followed by illustrations on Hamilton-Jacobi equations and quasi-linear hyperbolic equations. The consistency, existence and uniqueness results are all established. Furthermore, we clarify the relations of the geometrical solution to the entropy shock solution of scalar conservation laws as well as the viscosity solution of Hamilton-Jacobi equations. It is shown that the entropy shock in one dimensional space can be realized by compressing geometrical solution branches following an equal area principle; and the viscosity solution determined by the Lax-Hopf formula is just the smallest of branches of the geometrical solution.
An Additional LDL-Lowering Effect of Amlodipine; Not Only an Antihypertensive?

Hypertension is a modifiable risk factor for cardiovascular diseases and is associated with several metabolic disorders like dyslipidemia. Higher levels of triglyceride and low-density lipoprotein (LDL) are quite strong factors for the development of cardiovascular diseases. In this study, we investigated the effects of valsartan and amlodipine on the lipid profile in patients with newly diagnosed essential hypertension. We observed a beneficial effect of amlodipine on the lipid profile with a significant reduction of LDL compared to valsartan. In the treatment of hypertension, prior knowledge of the plasma cholesterol levels can be important in antihypertensive drug choice.
Digital signal regeneration with side-injection-light-controlled bistable laser diode as a wavelength converter

Digital optical signal regeneration with a SILC-BLD markedly improves the bit error rate of degraded optical signals. The extinction improved from 3 dB to 17 dB and intensity fluctuation was suppressed from 3 dB to 0 dB. This diode can not only regenerate the signal but also converts the signal wavelength at the same time without wavelength filters or isolators. <<ETX>>
Daily usage and efficiency of remote home monitoring in hypertensive patients over a one-year period

We evaluated daily self-monitored blood pressure (BP) data collected over one year using remote home monitoring. Fifty treated, moderately hypertensive subjects (26 males, mean age 50 years; 17 females, mean age 54 years; seven exclusions) were recruited for the study in which semi-automatic arm-cuff BP measurement devices were used. The daily self-monitoring regimen had two phases of usage: one of initial enthusiasm (the first one to two months) followed by a phase of lower usage (89% versus 64%, P<0.01). Monitoring was missed more often (P<0.01) during weekends (7.3 instances per patient) compared with workdays (5.0). Lack of motivation was not considered to be a major barrier. Approximately half of the study population was willing to continue the trial at the end of the one-year study. The occurrence of extreme BP values dropped significantly after the initial study month (P=0.02). In conclusion, routine remote BP monitoring is capable of collecting consistent and accurate data, with sufficient sensitivity to reveal trends.
Research challenges for 5G cellular architecture

Due to the centralized architecture of current cellular networks, the wireless link capacity as well as the bandwidth of the radio access and backhaul networks cannot practically cope with the exponential growth of mobile traffic. In order to meet this challenge, researches on the fifth generation (5G) cellular systems are highly anticipated in the next decade. Advanced technologies such as massive antennas and millimeter-wave systems, as well as direct communications will have significant impact on design of new heterogeneous network architecture. Cloud computing has emerged as a promising solution for providing high energy and spectral efficiency across software defined radio networks, in which the virtualization of communication hardware and software elements place stress on architecture and protocols. This paper analyses the main challenges raised by the new vision of cellular architecture, particularly focusing on issues related to the key emerging radio technologies, direct communications, cloud computing, as well as support of massive access.
