On-line safe path planning in unknown environments

s For the on-line safe path planning of a mobile robot in unknown environments, the paper proposes a simple Hopfield Neural Network ( HNN ) planner. Without learning process, the HNN plans a safe path with consideration of “ too close” or “ too far” . For obstacles of arbitrary shape, we prove that the HNN has no unexpected local attractive point and can find a steepest climbing path, if a feasible path(s) exists. To effectively simulate the HNN on sequential processor, we discuss algorithms with O(N) time complexity, and propose the constrained distance transformation-based Gauss-Seidel iteration method to solve the HNN. Simulations and experiments demonstrate the method has high real-time ability and adaptability to complex environments.
Marital Satisfaction in Refereed Women to Gorgan Health ‎Centers

Objective: One of the most important goals of marriage is the will to attain marital satisfaction. Marital ‎satisfaction is of prime importance and has the highest effect on the stability and failure of the ‎marriage. This study aimed to investigate marital satisfaction in the women who referred to ‎Gorgan Health centers. ‎ Method: This was a descriptive-analytical study conducted in Gorgan. Two hundred seventy married ‎women who referred to health centers were selected using multi stage sampling method. ‎Data were collected using a reliable and valid questionnaire and analyzed using SPSS 18. ‎ Results: The mean age of the participants was 33.39 ± 9.25 years. Marital satisfaction was in semi-desirable and desirable level in 66.3% and 33.7% of the participants, respectively. A significant ‎relationship was found between marital satisfaction and educational level of the participants (P<0.0001 χ2 = 32.09), educational level of the husband (P = 0.002 χ2 = 19.44), and occupation ‎of the husband (P<0.0001 χ2 = 19.17. ‎ Conclusion: Marital satisfaction of the participants was in desirable level. We recommend offering an ‎appropriate intervention to promote marital satisfaction particularly based on the mentioned ‎variables. ‎
Brain Signature Characterizing the Body-Brain-Mind Axis of Transsexuals

Individuals with gender identity disorder (GID), who are commonly referred to as transsexuals (TXs), are afflicted by negative psychosocial stressors. Central to the psychological complex of TXs is the conviction of belonging to the opposite sex. Neuroanatomical and functional brain imaging studies have demonstrated that the GID is associated with brain alterations. In this study, we found that TXs identify, when viewing male-female couples in erotic or non-erotic (“neutral”) interactions, with the couple member of the desired gender in both situations. By means of functional magnetic resonance imaging, we found that the TXs, as opposed to controls (CONs), displayed an increased functional connectivity between the ventral tegmental area, which is associated with dimorphic genital representation, and anterior cingulate cortex subregions, which play a key role in social exclusion, conflict monitoring and punishment adjustment. The neural connectivity pattern suggests a brain signature of the psychosocial distress for the gender-sex incongruity of TXs.
Rotational period of WD 1953 - 011- A magnetic white dwarf with a star-spot

WD 1953-011 is an isolated, cool (7920 +/- 200K) magnetic white dwarf (MWD) with a low average field strength (~70kG), and a higher than average mass (~0.74M solar ). Spectroscopic observations taken by Maxted et al. showed variations of equivalent width in the Balmer lines, unusual in a low-field white dwarf. Here we present V-band photometry of WD 1953-011 taken at seven epochs over a total of 22 months. All of the data sets show a sinusoidal variation of approximately 2 per cent peak-to-peak amplitude. We propose that these variations are due to a star-spot on the MWD, analogous to a sunspot, which is affecting the temperature at the surface, and therefore its photometric magnitude. The variations have a best-fitting period over the entire 22 months of 1.4418 d, which we interpret as the rotational period of the white dwarf.
Mesovarian leiomyomas in the rat.

Prolonged treatment with two chemically distinct beta-stimulants, Salbutamol and Terbutaline, resulted in mesovarian leiomyomas in Sprague-Dawley rats. Development of these tumors induced by Salbutamol was prevented by concurrent administration of the beta-blocker Propranolol. Mesovarian leiomyomas induced by Salbutomol did not show any regression or progression during a 44-week postdosing recovery period. This report also gives the first recorded incidence of spontaneous mesovarian leiomyomas in the rat. ImagesPLATE 1.PLATE 2.PLATE 3.PLATE 4.PLATE 5.PLATE 6.PLATE 7.PLATE 8.
The Asymptotic Giant Branch of NGC 205: The Characteristics of Carbon Stars and M Giants Identified from JHK' Images

J, H, and K' images are used to investigate the asymptotic giant branch (AGB) content of the Local Group dwarf elliptical galaxy NGC 205. The AGB on the (K, H-K) and (K, J-K) color-magnitude diagrams consists of two sequences: a near-vertical plume of giants with spectral types K and M and a red arm containing C stars. There are 320 C stars with Mbol < -4.1 and J-K > 1.5 within 2' of the nucleus. C stars account for 10% of the integrated luminosity of AGB stars brighter than Mbol = -3.75 near the center of NGC 205, and this is in excellent agreement with what is measured in intermediate-age clusters in the LMC. The most luminous AGB star has Mbol = -6.5, although variability introduces an uncertainty of a few tenths of a magnitude when using this as an estimate of the AGB tip brightness. Comparisons with models suggest that the brightest AGB stars formed within the past 0.1 Gyr and that the previous episode of star formation occurred a few tenths of a Gyr earlier. These results are consistent with star formation in NGC 205 being triggered by interactions with M31. These data also demonstrate that near-infrared imaging provides an efficient means of identifying C stars in nearby galaxies. The techniques used here to identify C stars and probe the AGB are well suited to studies of galaxies outside of the Local Group using data obtained with adaptive optics systems on large ground-based telescopes.
[Human eating: the scientific study of the obvious].

El objetivo de este número monográfico es presentar una serie de trabajos seleccionados entre aquellos que fueron enviados como respuesta a una convocatoria realizada a principios de 2015, que abordan la alimentación en su complejidad, no como producto del metabolismo, o la economía, o los valores que le dan sentido, sino como producto y, a la vez, productora de relaciones sociales. Especialmente, se presentan aquellos trabajos que tratan la alimentación en su múltiple vinculación con la salud y las políticas públicas. A través de la alimentación podemos estudiar de manera privilegiada la sociedad de los comensales, entendiendo que el evento alimentario siempre es situado (en un tiempo, en un espacio, en una sociedad determinada). Es por eso que a través de ella pueden ser analizados gran parte de los problemas económico-políticos e ideológico-culturales con mayor transparencia y menores sesgos que cuando se estudian en forma directa. Incluso, podemos leer con criterio alimentario-nutricional los estudios específicos (ecológicos, económicos, políticos, etc.), generando otras preguntas y descubriendo otros condicionamientos que pasan por alto los especialistas. Un enfoque relacional, en y desde la complejidad, nos permite ampliar nuestra comprensión y, al hacerlo, entendemos que no analizamos la alimentación sino –implícita o explícitamente– a la sociedad de la que es producto y a los comensales que la padecerán. Cuando se leen las relaciones sociales a través de la alimentación, descubrimos las paradojas que esta encierra. Porque se la ve tan explícita y repetida, que todos tenemos opinión, todos nos creemos expertos porque comemos todos los días, es tan obvia y evidente que no necesita explicación. Solo pasa a ser “la” problemática cuando falta pero, ante la suficiencia, se la olvida, se la secundariza y se la margina, hasta llegar a ser tan irrelevante que no se la ve si no se la problematiza especialmente, tal como ocurre con la mayoría de los aspectos de la cotidianeidad. Y esa es la situación actual, en un mundo que logró la suficiencia y, aparentemente, la comida dejó de ser un problema social para pasar a ser un placer individual. Es aquí y ahora, problematizando lo obvio, lo que está frente a nuestras narices pero extiende sus raíces más allá del continente y del tiempo que, a través del estudio de la alimentación, podemos comprender algo de la realidad compleja que nos toca enfrentar.

A dutch prison officer's work: balancing between prison policy, organizational structure and professional autonomy

L'etude de la situation des guardiens de prisons a la fin des annees 1980 montre que les difficultes auxquelles les guardiens ont a faire face et le stress de la profession ne sont pas autant connectes aux elements supposes conflictuels de leur role professionnel (controler, prendre soin et rehabiliter), mais davantage a leur position au sein de l'organisation penitentiaire. Aux Pays-Bas, apres la seconde Guerre Mondiale, alors que le systeme carceral s'est developpe selon une orientation plus humaine, laissant aux prisonniers une plus grande autonomie, le role professionnel des gardiens est devenu (de ce fait) plus important alors que leur position professionnelle devenait moins centrale au sein de l'organisation hierarchique.
Evaluating Cross-National Variations in Under-Declared Wages in the European Union: An Exploratory Study

In recent years, there has been a growing recognition that some employers illegitimately under-declare employees’ salaries by paying an undeclared (‘envelope’) wage in addition to their official declared salary. The aim of this paper is to evaluate critically the competing perspectives that variously explain the cross-national variations in the propensity of employers to under-declare wages to be: simply a legacy of under-development (modernisation perspective); due to high taxes, state corruption and burdensome regulations and controls (neo-liberal perspective), or a result of inadequate state intervention in work and welfare arrangements which leaves workers less than fully protected (structuralist perspective). Reporting the results of a 2007 Eurobarometer involving 26,659 face-to-face interviews across the 27 member states of the European Union (EU-27) to evaluate the prevalence, size and nature of envelope wage arrangements across the EU-27, this exploratory study reveals that envelope wages are more common, larger and more likely to be for regular work in poorer, more corrupt and less equal nations with lower levels of taxation, state intervention in the labor market, social protection and redistribution via social transfers. The paper concludes by discussing both the theoretical and policy implications.
Hopes and Fears: Community Cohesion and the ‘White Working Class’ in One of the ‘Failed Spaces’ of Multiculturalism

Since 2001, community cohesion has been an English policy concern, with accompanying media discourse portraying a supposed failure by Muslims to integrate. Latterly, academia has foregrounded White majority attitudes towards ethnic diversity, particularly those of the ‘White working class’. While questioning this categorisation, we present data on attitudes towards diversity from low income, mainly White areas within Dewsbury, West Yorkshire, a town portrayed in media discourse as one of the ‘failed spaces’ of multiculturalism. Drawing on mixed methods research, we present and discuss data that provide a complex message, seemingly confirming pessimistic analyses around ethnic diversity and predominantly White neighbourhoods but also highlighting an appetite within the same communities for greater and more productive inter-ethnic contact. Furthermore, anxieties about diversity and integration have largely failed to coalesce into broad support for organised anti-minority politics manifest in groups such as the English Defence League.
The rate of the founder Jewish mutations in BRCA1 and BRCA2 in prostate cancer patients in Israel

Inherited predisposition occurs in 5–10% of all prostate cancer (CaP) patients, but the genes involved in conferring genetic susceptibility remain largely unknown. Several lines of evidence indicate that germline mutations in BRCA1 and BRCA2 might be associated with an increased risk for CaP. Three mutations in these two genes (185delAG and 5382InsC (BRCA1) and 6174delT (BRCA2) occur in about 2.5% of the general Ashkenazi population, and the 185delAG BRCA1 mutation, in up to 1% of non-Ashkenazi Jews. In order to assess the contribution of these germline mutations to prostate cancer in Jewish Israeli patients, we tested 174 unselected prostate cancer patients (95 of Ashkenazi origin) for these mutations by PCR amplification and modified restriction enzyme digests. Patient's age range was 45–81 years (median 66), and in 24 (14.4%) the disease was diagnosed prior to 55 years of age. Nineteen (11%) and 12 (6.9%) patients had a first or second degree relative with CaP or breast cancer, respectively. Overall, five mutation carriers were detected: 2/152 (1.3%) 185delAG, 2/104 (2%) 5382InsC, and 1/158 (0.6%) 6174delT. In all carriers, the disease was diagnosed after the age of 55, and only one of them had a family history of breast and CaP. In addition, no allelic losses at the BRCA1 locus were demonstrated in 17 patients with a family history of CaP, using seven microsatellite markers. We conclude that the rate of the predominant Jewish BRCA1 and BRCA2 mutations in CaP patients does not significantly differ from that of the general population, and that mutational inactivation of the BRCA1 is rare in familial CaP. Thus, germline BRCA1 and BRCA2 mutations probably contribute little to CaP occurrence, to inherited predisposition, and to early onset disease in Jewish individuals. © 2000 Cancer Research Campaign
Magnesium Sulfate in Aneurysmal Subarachnoid Hemorrhage: A Randomized Controlled Trial

Background and Purpose— Magnesium reverses cerebral vasospasm and reduces infarct volume after experimental subarachnoid hemorrhage (SAH) in rats. We aimed to assess whether magnesium reduces the frequency of delayed cerebral ischemia (DCI) in patients with aneurysmal SAH. Methods— Patients were randomized within 4 days after SAH. Magnesium sulfate therapy consisted of a continuous intravenous dose of 64 mmol/L per day, to be started within 4 days after SAH and continued until 14 days after occlusion of the aneurysm. The primary outcome DCI (defined as the occurrence of a new hypodense lesion on computed tomography compatible with clinical features of DCI) was analyzed according to the “on-treatment” principle. For the secondary outcome measures “poor outcome” (Rankin >3) and “excellent outcome” (Rankin 0), we used the “intention-to-treat” principle. Results— A total of 283 patients were randomized. Magnesium treatment reduced the risk of DCI by 34% (hazard ratio, 0.66; 95% CI, 0.38 to 1.14). After 3 months, the risk reduction for poor outcome was 23% (risk ratio, 0.77; 95% CI, 0.54 to 1.09). At that time, 18 patients in the treatment group and 6 in the placebo group had an excellent outcome (risk ratio, 3.4; 95% CI, 1.3 to 8.9). Conclusions— This study suggests that magnesium reduces DCI and subsequent poor outcome, but the results are not yet definitive. A next step should be a phase III trial to confirm the beneficial effect of magnesium therapy, with poor outcome as primary outcome.
UC San Francisco UC San Francisco Previously Published Works Title Genetic CJD with a novel E 200 G mutation in the prion protein gene and comparison with E 200 K mutation cases

A novel point mutation resulting in a glutamate-to-glycine substitution in PRNP at codon 200, E200G with codon 129 MV polymorphism (cis valine) and type 2 PrP was identified in a patient with a prolonged disease course leading to pathology-proven Jakob-Creutzfeldt disease. Despite the same codon as the most common genetic form of human PRNP mutation, E200K, this novel mutation (E200G) presented with a different clinical and pathological phenotype, including prolonged duration, large vacuoles, no vacuolation in the hippocampus, severe neuronal loss in the thalamus, mild cerebellar involvement, and abundant punctate linear and curvilinear deposition of PrP in synaptic boutons and axonal terminals along the dendrites.
The Association of Calf Circumference with Resting Pulse Rate in Community-dwelling Healthy Elderly Women —Pilot Study—

[Purpose] High resting blood pressure and heart rate are associated with the risk of cardiovascular events. In patients with decreasing amounts of slow twitch muscle fiber, hypertension may develop and resting heart rate may increase. Measurement of the amount of slow twitch muscle fiber and capillary density using muscle biopsy is inconvenient and expensive. Therefore, a better screening test is required to determine these parameters for prevention of cardiovascular events. In this study, relationships among calf circumference, resting blood pressure, and pulse rate in the soleus muscle were investigated. [Subjects] Healthy elderly women (n= 19, 61–84 years of age) living in the community were the subjects of this study. [Methods] Blood pressure was measured using an automatic hemodynamometer on the left arm. The calf circumference was measured, and pulse rate was measured on the left radial artery for 1 min by palpation. [Results] No correlations were observed between calf circumference, resting systolic or diastolic pressure, pulse pressure, or mean blood pressure. However, an inverse correlation was observed between calf circumference and resting pulse rate. [Conclusion] Calf circumference measurement may be used as a screening test for resting pulse rate. This test may be useful for the prevention of cardiovascular events.
The ALPS project release 2.0: open source software for strongly correlated systems

We present release 2.0 of the ALPS (Algorithms and Libraries for Physics Simulations) project, an open source software project to develop libraries and application programs for the simulation of strongly correlated quantum lattice models such as quantum magnets, lattice bosons, and strongly correlated fermion systems. The code development is centered on common XML and HDF5 data formats, libraries to simplify and speed up code development, common evaluation and plotting tools, and simulation programs. The programs enable non-experts to start carrying out serial or parallel numerical simulations by providing basic implementations of the important algorithms for quantum lattice models: classical and quantum Monte Carlo (QMC) using non-local updates, extended ensemble simulations, exact and full diagonalization (ED), the density matrix renormalization group (DMRG) both in a static version and a dynamic time-evolving block decimation (TEBD) code, and quantum Monte Carlo solvers for dynamical mean field theory (DMFT). The ALPS libraries provide a powerful framework for programmers to develop their own applications, which, for instance, greatly simplify the steps of porting a serial code onto a parallel, distributed memory machine. Major changes in release 2.0 include the use of HDF5 for binary data, evaluation tools in Python, support for the Windows operating system, the use of CMake as build system and binary installation packages for Mac OS X and Windows, and integration with the VisTrails workflow provenance tool. The software is available from our web server at http://alps.comp-phys.org/.
The Perils and Promises of Praise The wrong kind of praise creates self-defeating behavior. The right kind motivates students to learn.

V J f t 0 e often hear these M m^L m days that we've ^L m ^L M produced a genera• # • # tion of young people ^M ^m who can't get through the day without an award. They expect success because they're special, not because they've worked hard. Is this true? Have we inadvertently done something to hold back our students? 1 think educators commonly hold two beliefs that do just that. Many believe that (1) praising students' intelligence builds their confidence and motivation to leam, and (2) students' inherent intelligence is the major eause of iheir achievement in school. Our research has shown that the first belief is false and that the second can be harmful—even for the most competent students. As a psychologist, I have studied student motivation for more than 35 years. My graduate students and I have looked at thousands of children, asking why some enjoy learning, even when it's hard, and why they are resilient in the face of obstacles. We have learned a great deal. Research shows us how to praise students in ways that yield motivation and resilience. In addition, specific interventions can reverse a student's slide into failure during the vulnerable period of adolescence.
Evaluation of repetitive transcranial magnetic stimulation for treatment-resistant major depression and the impact of anxiety symptoms on outcome

ABSTRACT Objective: The aim of this study was to evaluate the efficacy of repetitive transcranial magnetic stimulation (rTMS) in patients with treatment-resistant major depression and to explore the relationship between the outcome and comorbid anxiety symptoms. Methods: The study was performed on 36 patients with treatment-resistant major depression. Patients received 15 rTMS sessions to their left dorsolateral prefrontal cortex with 110% motor threshold intensity, 20 Hz frequency, and 1000 pulses per day over a three-week period with the same stimulation parameters. Patients were assessed using Sociodemographics Form, the Montgomery–Asberg Depression Rating Scale (MADRS), and the Hamilton Anxiety Rating Scale (HAM-A) at baseline both before initiating rTMS treatment and on the first day following their last rTMS treatment session. Results: Decreased scores in patients’ MADRS and HAM-A (including subscales) were statistically significant with large effect sizes (r > 0.5) after rTMS treatment. Pretreatment HAM-A total scores and HAM-A somatic subscale scores were significantly higher in those who responded to rTMS (p = .046, p = .048). There were negative correlations between post-treatment MADRS scores and pretreatment HAM-A somatic and psychic subscale scores. Conclusions: While the main limitations of the study are its design and small sample size, the findings suggested that comorbid anxiety symptoms, particularly somatic anxiety, could predict the response to rTMS in treatment-resistant major depressive disorder.
Active exploration using scheme of autonomous distribution for landmarks

This paper investigates the on-line autonomous distribution for landmarks and the active exploration in environment without or lack of landmarks/features, such as disaster conditions and polar region. In such situation, the robot enters the environment carrying some landmarks and distributes them according to the rules given in this paper. The utility of the landmark distribution is analyzed. Then, based on the extended Kalman filter (EKF), the active exploration is converted into a problem of multi-objective optimization, in which the objective function includes three aspects, i.e. the accuracy of localization and mapping, the predictive area of the unknown environment that will be explored in next step and the information gain provided by the distributed landmarks respectively. The robot chooses the control input that optimizes the objective function such that accurate localization, high-quality mapping and complete exploration will be realized. And then, the supplementation and the redundancy elimination for landmarks are implemented. At last, a set of simulations is presented to show the effectiveness of our approach.
