On the Newtonian Anisotropic Configurations

In this paper we are concerned with the effects of anisotropic pressure on the boundary conditions of anisotropic Lane-Emden equation and homology theorem. Some new exact solutions of this equation are derived. Then some of the theorems governing the Newtonian perfect fluid star are extended taking the anisotropic pressure into account

Design of Adiabatic MTJ-CMOS Hybrid Circuits

Low-power designs are a necessity with the increasing demand of portable devices which are battery operated. In many of such devices the operational speed is not as important as battery life. Logic-in-memory structures using nano-devices and adiabatic designs are two methods to reduce the static and dynamic power consumption respectively. Magnetic tunnel junction (MTJ) is an emerging technology which has many advantages when used in logic-in-memory structures in conjunction with CMOS. In this paper, we introduce a novel adiabatic hybrid MTJ/CMOS structure which is used to design AND/NAND, XOR/XNOR and 1-bit full adder circuits. We simulate the designs using HSPICE with 32nm CMOS technology and compared it with a non-adiabatic hybrid MTJ/CMOS circuits. The proposed adiabatic MTJ/CMOS full adder design has more than 7 times lower power consumtion compared to the previous MTJ/CMOS full adder

Designing Precoding and Receive Matrices for Interference Alignment in MIMO Interference Channels

Interference is a key bottleneck in wireless communication systems. Interference alignment is a management technique that align interference from other transmitters in the least possibly dimension subspace at each receiver and provides the remaining dimensions for free interference signal. An uncoordinated interference is an example of interference which cannot be aligned coordinately with interference from coordinated part; consequently, the performance of interference alignment approaches are degraded. In this paper, we propose a rank minimization method to enhance the performance of interference alignment in the presence of uncoordinated interference sources. Firstly, to obtain higher multiplexing gain, a new rank minimization based optimization problem is proposed; then, a new class of convex relaxation is introduced which can reduce the optimal value of the problem and obtain lower rank solutions by expanding the feasibility set. Simulation results show that our proposed method can obtain considerably higher multiplexing gain and sum rate than other approaches in the interference alignment framework

Compressed sensing and robust recovery of low rank matrices

In this paper, we focus on compressed sensing and recovery schemes for low-rank matrices, asking under what conditions a low-rank matrix can be sensed and recovered from incomplete, inaccurate, and noisy observations. We consider three schemes, one based on a certain Restricted Isometry Property and two based on directly sensing the row and column space of the matrix. We study their properties in terms of exact recovery in the ideal case, and robustness issues for approximately low-rank matrices and for noisy measurements

Epidemiology of female reproductive cancers in Iran: Results of the gholestan population-based cancer registry

Background: Malignancies of the female reproductive tract are estimated to be the third most common group of cancers in women. Objectives: We here aimed to present their epidemiological features in Golestan provincelocated in Northeast of Iran. Materials and Methods: Data on primary female reproductive cancers diagnosed between 2004-2010 were obtained from Golestan Population-based Cancer Registry (GPCR). CanReg-4 and SPSS software were used for data entry and analysis. Age standardized incidence rates (ASR) (per 100,000 person-years) were calculated using the world standard population. Poisson regression analysis was used to compare incidence rates. P-values of less than 0.05 were considered as significant. Results: A total of 6,064 cancer cases were registered in Golestan females in the GPCR during 2004-2010, of which 652 cases (11%) were female reproductive cancers. Cancers of the ovary (ASR=6.03) and cervix (ASR=4.97) were the most common. We found significant higher rates in females living in cities than in villages. Our results showed a rapid increase in age specific incidence rates of female reproductive cancers at the age of 30 years. Conclusions: We found significant higher rates of female reproductive cancers among residents of cities than villages. Differences in the prevalence of risk factors including reproductive behavior between the two populations may partly explain such diversity. Our results also showed a rapid increase in incidence rates of these cancers in young age females. Further studies are warranted to determine risk factors of female reproductive cancers in our population

Epidemiology of Urban Traffic Accident Victims Hospitalized More Than 24 Hours in a Level III Trauma Center, Kashan County, Iran, During 2012-2013

Background: Posttraumatic Stress Disorder (PTSD) is a severe anxiety disorder occurred due to past adverse experiences. Several researches have demonstrated that PTSD is quite common among patients discharged from critical care unit. Objectives: This study aimed to investigate the prevalence of PTSD and its related factors among patients discharged from critical care units in Kashan, Iran, during 2014. Patients and Methods: A descriptive prospective study was performed on 332 patients admitted to critical care units of Kashan Shahid Beheshti Hospital using a convenience sampling method. Data were collected in wards during hospitalization and one month after their discharge from hospital using questionnaires on demographic, medical information and PTSD Checklist (PCL). The PCL scores of 45 or more were considered as PTSD. Data were analyzed using chi-square, t-test, Mann-Whitney U and logistic regression. Results: From a total of 332 patients, 160 cases (48.2%) had PTSD and the mean total PCL score in participants was 44.24 ± 19.89. There was a significant difference between the total score of PTSD and its domains in patients with and without PTSD. the univariate analysis showed a significant association between PTSD and increasing age, increased length of hospital stay, more children, having additional comorbidities, unemployed, use of mechanical ventilation (P < 0.001), drug abuse (P = 0.003) and single patients (P = 0.028). However, there was no significant association between PTSD and gender, type of the critical care unit, level of education and admission due to trauma. However, in multivariate analysis using logistic regression, factors associated with PTSD were older age of the participants, use of mechanical ventilation having additional comorbidities, unemployed (P<0.001) and being single (P=0.04) Conclusions: Prevalence of PTSD is high among patients discharged from ICUs and some medical individual factors such as elderly, unemployed, being single, using mechanical ventilation and pre-existing diseases are risk factors. Therefore, it is recommended to perform appropriative educational plan for these patients to reduce the risk of PTSD

It has been suggested that these populations do not access psychiatric treatment. The aim of this study was to establish rates of psychiatric in- and outpatient treatments prior to imprisonment in female prisoners and to explore reasons for discontinuation of such treatments.Methods150 consecutively admitted female prisoners were interviewed in Berlin, Germany. Socio-demographic characteristics, mental disorders, and previous psychiatric in- and outpatient treatments were assessed by trained researchers. Open questions were used to explore reasons for ending previous psychiatric treatment.ResultsA vast majority of 99 prisoners (66%; 95% CI: 58¿73) of the total sample reported that they had previously been in psychiatric treatment, 80 (53%; 95 CI: 45¿61) in inpatient treatment, 62 (41%; 95 CI: 34¿49) in outpatient treatment and 42 (29%; 21¿39) in both in- and outpatient treatments. All prisoners with psychosis and 72% of the ones with any lifetime mental health disorder had been in previous treatment. The number of inpatient treatments and imprisonments were positively correlated (rho¿=¿0.27; p¿<¿0.01). Inpatient treatment was described as successfully completed by 56% (N¿=¿41) of those having given reasons for ending such treatment, whilst various reasons were reported for prematurely ending outpatient treatments.ConclusionThe data do not support the notion of a general `mental health treatment gap¿ in female prisoners. Although inpatient care is often successfully completed, repeated inpatient treatments are not linked with fewer imprisonments. Improved transition from inpatient to outpatient treatment and services that engage female prisoners to sustained outpatient treatments are needed

Epidemiology of Home-Related Injuries During a Six-Year Period in Kashan, Iran

Background: Injury is one of the leading causes of morbidity and mortality in the world, and the home is one of the most common places for these types of injuries. Objectives: This study is designed to investigate the epidemiology of home-related injuries in Kashan, Iran. Patients and Methods: This investigation is a retrospective cross-sectional study on existing data from the data bank of the Trauma Research Center at Kashan University of Medical Sciences during a six-year period. Demographic data such as; sex, age, place of residence, educational and occupational status, injury mechanism, injured organs and injury outcomes, were analyzed using a chi-squared test and P < 0.05 was considered significant. Results: The number of home injuries was 10146 in total, that included about 25.2% of all injuries in Kashan City. Most of the injured people were men (58.3%), 87.4% lived in the city and 18.6% were aged more than 64 years. The majority (42.7%) had a primary or secondary school education and 27.2% were housewives. Falling from a height was the most common cause of injury (55.3%). Limbs were the most common body region that was injured (73.7%). Young men (under 15 years) and older women (over 65 years) had more injuries, especially from falls. There was a statistically significant difference between the sex and age of the injured people (P < 0.001), sex and injury mechanism (P < 0.001), and also between the injury mechanism and sex in the age groups (P < 0.001). Conclusions: The most common injury mechanism in regard to home accidents was falls; therefore fall-related injury prevention programs should be designed to make homes safer and education should focus on changes in lifestyle to reduce fall susceptibility
