Exploration of biological causes of psychological problems in polycystic ovary syndrome (PCOS)

Background: Polycystic ovary syndrome (PCOS) affects up to 10% of women, and is characterised by elevated testosterone (T) levels. Women with PCOS have higher scores than healthy women on a range of measures of psychological problems. Objective: To test the hypotheses that: 1/ The female fetus in a PCOS pregnancy experiences elevated T levels; 2/ T causes mood disturbance in women with PCOS. 3/ women with PCOS show more signs of mood disturbance typical of symptoms of reactive hypoglycaemia than healthy controls. Design: Mainly between-groups cross-sectional studies. Also two meta-analyses. Setting: The research took place mainly in two London gynaecology clinics, University College London Hospital (UCLH) and the Royal Free Hospital, Hampstead (RFH). Some of the research was conducted online, and at three other gynaecology and fertility clinics. Participants: Participants were recruited from hospital clinics, support groups for women with PCOS, or the internet. Most participants were women aged 18-40. Outcome Measures: Testosterone; psychometric measures of mood disturbance. Results: 1/ Elevated T was found in the umbilical cord blood of the female fetus in PCOS pregnancies; 2/ Mood problems in PCOS were not directly caused by T. 3/ Women with PCOS showed higher levels of mood problems typical of hypoglycaemia than controls. Conclusions: The findings suggest the female fetus in a PCOS pregnancy may be exposed to relatively high levels of T. Mood problems in adults with PCOS are possibly caused by the direct effects of low blood glucose and indirect effects of T (e.g. obesity) than direct effects of T. Further research using the gold-standard biochemical assessment methods is required for any replications of these findings.
CMS event reconstruction status in Run 2

LHC Run2 began in April 2015 with the restart of the collisions in the CERN Large Hadron Collider. In the perspective of the offline event reconstruction, the most relevant detector updates appeared in 2017: the upgrade of the Pixel Detector, with the insertion of an additional layer closer to the beams, and the improved photodetectors and readout chips for the Endcap Hadron Calorimeter, which allow a finer longitudinal segmentation. The long shutdown between Run1 and Run2 was instrumental in the optimization of the reconstruction code and for the introduction of new algorithms to mitigate sensitivity to increased pileup, especially to out-of-time contribution with the advent of 25 ns separation between collisions compared to 50 ns in Run1. Such an optimization continued in the following years, when the reconstruction code of CMS evolved together with the improving of the performance of the LHC. The current status of the reconstruction software of the CMS experiment is described here, with emphasis on some of the recently integrated developments.
A Review of CMOS Variable Gain Amplifiers and Programmable Gain Amplifiers

ABSTRACT CMOS implementations of variable gain amplifiers (VGAs) and programmable gain amplifiers (PGAs) are reviewed in this paper. They fall into two categories: Radio Frequency VGA/PGAs and Intermediate Frequency VGA/PGAs. Most approaches to realize gain tuning create linear VGAs and consequently exponential conversion are required. The CMOS circuit realizations of exponential converters are complex and are also reviewed. In contrast, PGAs benefit from their flexible gain control mode and hence have much simpler structures. However, lower distortions and higher gain accuracy can be achieved for PGAs. Therefore, PGAs are preferred in most scenarios. This paper also presents a CMOS Gilbert VGA and a novel high linearity constant bandwidth PGA with improved common mode rejection. The DC-offset cancellation methods are reviewed as well. Finally, trends of VGAs/PGAs in modern receivers are analysed.
Arbitrary Multiplexing Rates For Video Broadcasting In Broadband Wireless Transmission Systems

In mobile communication system, video streaming applications have been increased rapidly and it demands more bandwidth. The multiplexing-diversity tradeoff is a major problem for the case of video broadcasting systems. In the existing schemes, the transmission is possible only with the integer multiplexing rates. The proposed HCDD scheme is capable of transmitting the non-integer multiplexing rates too. On contrary to the existing system, representing the data transmission on spatial dimension , the proposed scheme provides the benefit of representing the same on subcarrier frequency dimension. In the existing MIMO-OFDM schemes, in which all subcarriers transmit at same rate, the proposed HCDD scheme can support different rates at each subcarrier or for a group of subcarriers. One of the major advantage of HCDD is that the rate of space-time codes can be adjusted flexibly according to the system requirements by assigning k r to different subcarriers. Also the number of transmitting antennas can also be adjusted flexibly. The proposed HCDD can be applied to systems with only two transmitting antennas. Moreover the proposed scheme has less stringent constraints on channel coherence and is less complex.
TESAURUS BIOTEKNOLOGI: SEBAGAI ALAT BANTU PENGINDEKSAN DOKUMEN

Thesauri contain words or terms that are used as a tool to identify a concept or an idea precisely and correctly. The advantage of thesauri is because they are considered as better tools to find out information or document with a high degree of invention and precision. Thesauri are invaluable tools for analysts in deciding descriptors as keywords of a document. In accordance with its structure or composition, thesaurus of biotechnology consists of three parts: a hierarchy, an alphabetic, and an index. The relationships of terms from specific (narrow terms) to general (broad terms) are shown in the structure of the hierarchy. The next structure is an alphabetic, which is a form-changed from hierarchical thesaurus that is re-arranged alphabetically. The relationship between one term and other terms is shown, based on specificity level of a term meaning. The last structure is index. It is made by a team to help users browse terms in thesaurus quickly. Each of the terms will appear in alphabetical sequence with different frequencies.
Rhéologie des pâtes granulaires

Cette these porte sur la rheologie des pâtes granulaires. L'image classique pour les pâtes granulaires est qu'il y a une transition d'un ecoulement frictionnel vers un ecoulement lubrifie lors de l'augmentation du taux de cisaillement. Nous montrons qu'il existe en realite une transition d'un ecoulement localise vers un ecoulement non-localise. Le parametre pertinent caracterisant cette transition est le nombre de Leighton, qui est le rapport entre les forces lubrifiee et frictionnelle. Ce nombre definit un taux de cisaillement critique au-dessous duquel aucun ecoulement stationnaire sans localisation ne peut exister. Par ailleurs, en menant a la fois des experiences en IRM et des experiences de rheologie classique, nous definissons une viscosite pour les pâtes granulaires. Il faut pour cela tenir compte de la migration des particules vers les zones faiblement cisaillees lors de l'ecoulement, migration qui engendre un profil de concentration des particules. La viscosite est donnee par une loi constitutive constituee de trois equations : l'equation de la courbe d'ecoulement, l'equation de Krieger-Dougherty, et le rapport entre contrainte de cisaillement et premiere difference de contraintes normales. Enfin, nous etudions des suspensions rheoepaississantes de fecule de mais qui presentent egalement une transition d'un regime localise vers un regime non-localise autour d'un seuil de rheoepaississement.
Online Self and Discrepancy:Who We Are Online, Offline, and Hoping To Be

Abstrak Pembentukan identitas sangatlah penting pada masa remaja. Namun, dengan teknologi yang berkembang semakin kompleks, satu aspek dalam kehidupan remaja menjadi sangat penting, yaitu diri dalam dunia maya. Dalam interaksi dunia maya, seperti interaksi sosial lainnya, setiap individu—dalam kasus ini remaja—ingin untuk dipandang dan juga berperilaku dengan cara-cara tertentu. Maka dari itu, remaja menciptakan sebuah set atribut yang unik dan berbeda dengan diri mereka di dunia nyata. Sebagai contohnya, sebuah individu bisa saja bersifat pemalu di dunia nyata, namun mereka bisa sangat aktif dan terbuka saat berada di dunia maya. Seringnya, perbedaan ini mengakibatkan banyak masalah, termasuk menghabiskan banyak waktu di dunia maya untuk mengembangkan diri dunia mayanya dan mengabaikan kewajiban dunia nyatanya. Penelitian ini bertujuan untuk menjelaskan fenomena ini. Gambaran diri ideal, dunia maya, dan dunia nyata ditanyakan kepada subjek. Peneitian ini akan menjelaskan tentang tiga masalah utama, yaitu: 1). Apakah diri dunia maya dan dunia nyata berbeda drastik? 2). Jika memang berbeda, sebagaimana berbedakah dan kenapa perbedaan ini dibutuhkan? 3). Diri manakah yang lebih disukai dan mirip dengan diri ideal? Kata kunci : Online and online self, identitas, ideal self.
Nonlinear-Free Surface Effects: Experiments and Theory

Abstract : The object of this report is to present the results of some simple two-dimensional experiments in which the surface of the water is displaced a good deal from its undisturbed position, and for which linear theory is likely to be in error. Particular attention is paid to the point of intersection of the free surface and a moving body, where the confluence of boundary conditions can cause singularities in the free surface displacements and velocities, as predicted by linear theory. These singularities appear to be avoided in the real fluid by the formation of jets, which at the scale of the experiments, quickly break up into spray under the action of surface tension. Nevertheless it is known that potential theory is adequate to describe the formation of jets and therefore some local model, valid around the intersection point and based on potential theory, is being sought for later matching to appropriate far field conditions. Such far field or outer solutions may be calculated with existing programs, and it is hoped that when complemented by an inner solution, they will provide a reasonably complete description of many extreme wave or extreme motion problems e.g., ship capsize and slamming. For the most part the experiments have been performed at high speed: this means that it is approximately correct to ignore gravity in the local region and this effects a considerable simplification to the theory.
Using the ARGO-YBJ experiment to determine the attenuation and the absorption lengths

Using the data taken by the ARGO-YBJ experiment (606 g/cm, Tibet, P.R.China) since July to December 2006, with the measurement of the EAS size spectrum, the attenuation length is calculated on the method of constant intensity cut, and the absorption length is also determined. By comparing with the result from the ARGO-YBJ test experiment, our preliminary results show a good consistency.
THE EFFECT OF SLOW STROKE BACK MASSAGES ON ANXIETY AMONG PRIMIGRAVID WOMEN

Received: Sep. 2009 Accepted: Mar. 2010 Corresponding author: Bazrafshan MR e-mail: Mrbazr@sums.ac. ir Background & Objective: Pregnancy is a situational crisis in women's lives that is potentially related to anxiety. Massage, a kind of relaxation technique, is a non-pharmacological intervention for anxiety relief. Slow stroke back massage is an independent nursing procedure that is closely associated with the caring nature of nursing. This study aimed to assess the effect of slow stroke back massages on anxiety level among primigravid women in two clinics in Shiraz in 2007. Methods & Materials: In this clinical trial, 80 primigravid women aged 1535 who were in the 3 trimester of pregnancy were enrolled in the study. The participants were randomly allocated in the intervention and control groups. The intervention group received slow stroke back massage for 10 minutes in three consecutive mornings. Anxiety level was measured before and immediately after the intervention in both groups. Data were gathered using the state anxiety Spielberger questionnaire and were analyzed using Chi-square test, Fisher's Exact test, Paired t-test, and Independent statistic test (t-test). Results: The means of the anxiety level were 51±6.6 and 49.90±6.6 at baseline in the intervention and control groups, respectively (P=0.460). After the intervention, the means of anxiety level were 48.18±6.52 and 51.50±7.39 in the intervention and control groups, respectively (P=0.036). Conclusion: According to the results, slow stroke back massage seems to be an effective nursing intervention for anxiety relief in primigravid women. It provides an opportunity for nurses to offer individualized and holistic patient care.
Object mobility in a distributed object-oriented system

This dissertation studies the movement of objects both large and small within a locally distributed system. We propose that object mobility at a fine granularity can be a powerful tool for simplifying the construction of distributed applications. The unit of mobility in previous systems has typically been an address space. We propose using data of any size as the unit of mobility. Our study of fine-grained mobility is based on a new programming language called Emerald for which we have implemented a run-time kernel. Emerald supports a single model of computation: the object. All objects are described using a uniform semantic model. They can move freely within the system to take advantage of distribution and respond to dynamically changing requirements. We say that Emerald has fine-grained mobility because all objects can move regardless of size. Process migration is supported; light-weight processes that are executing within a migrating object are also migrated on-the-fly. Our design of Emerald emphasizes efficiency, in particular, efficient communication between potentially distributed objects located on the same machine. By integrating distribution concepts into the programming language, the compiler is able to generate more efficient code for objects that do not require full generality. Emerald supports call-by-reference semantics--even for remote procedure calls. We introduce a special parameter passing mode, call-by-move which can be used to move parameters for efficiency reasons. We present a design for a distributed on-the-fly garbage collector. The design includes a novel faulting mechanism that allows user processes to proceed during collection. This dissertation discusses aspects of language design related to mobility and the design and implementation of an efficient Emerald kernel. Measurements of the system and of several small applications are presented.

The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, through international peer-review processes, as a prerequisite for the promotion of chemical safety, and to provide technical assistance in strengthening national capacities for the sound management of chemicals.
Phase retrieval from coded diffraction patterns

The classical iterative phase retrieval method has the disadvantages of poor anti-noise performance,and can not converge to the global optimal solution.The optimization of phase retrieval technology via PhaseCut(PC)transforms the phase retrieval problem into quadratic constrained convex programming problem,and gets the global optimal solution up to global phase.Some more structured and less random ternary masks and octonary masks are used to code the signal of interest to acquire diffraction patterns which can recover the missing phase information by solving PhaseCut.Simulations are firstly performed to test the one dimensional complex signal and compare the success rates of reconstruction using different masks.Secondly,the reconstruction results of two dimensional molecular images are compared for different masks.The results show that the method can obtain better reconstruction results than the traditional method which is based on binary masks.Moreover,the recovered phase distributions are loaded to the optical reconstruction system based on liquid crystal on silicon(LCOS). The diffraction pattern of real experiment proves the effectiveness of the proposed method.
Programming – Flow in the convergence of digital media platforms and television

This essay updates Raymond Williams’ flow by defining its contemporary logics – televisible and invisual. The televisible are both media content and visual digital media forms that shape – and are shaped by – interactions with media content through digital media platforms. The invisual are unseen operations of software, algorithms and other processes that configure and manifest the televisible. A case study of Netflix illuminates how this reconceived flow series functions as a framework for understanding the stakes of digital media platforms that both foster possibilities for user interactivity and attenuate users to industrial models for audienceship and programming.

THE VIEW OF FACULTIES AND MEDICAL STUDENTS ABOUT EVALUATION OF FACULTY TEACHING EXPERIENCES

Introduction: Using students' view for teacher evaluation is a common method. This study was designed to investigate the view of faculties and medical students about faculty teaching experiences. Materials and Methods: 100 medical students and 35 faculties from Jahrom University of Medical Sciences were participated in this study. Two separate questionnaires were designed for this purpose and after determining validity and reliability completed by teachers and students. Results: 70.9 percent of faculties reported that they are satisfied with evaluation by students. 48.6 percent of them reported that feedback from this evaluation improved their teaching. 48.8 percent of them thought that some students behave spitefully. 60 percent reported self assessments as a useful method for evaluation of their own teaching. The majority of medical students (76.6%) reported that teachers' communication skills are one of the important factors in teacher evaluation. 67.4 percent of them reported that they completed the teachers' evaluation forms carefully and 60.9 percent of them asserted that teachers, who take difficult examinations, have lower grades in evaluation forms. Conclusion: In general, most teachers are agreed with teacher evaluation. Since students' opinion about their teachers is influenced by some factors which have no close relationship with the evaluation subject and is merely related to other factors, using other evaluation methods such as self evaluation and peer evaluation seems to be necessary. In addition, we should establish a single national and standard method for teacher evaluation all over the country .
