description: MANET is a kind of Ad hoc network with mobile, wireless nodes. Because of its special characteristics like dynamic topology, hop-by-hop communications and easy and quick setup, MANET faced lots of challenges allegorically routing, security and clustering. The security challenges arise due to MANETs self-configuration and self-maintenance capabilities. In this paper, we present an elaborate view of issues in MANET security. Based on MANETs special characteristics, we define three security parameters for MANET. In addition we divided MANET security into two different aspects and discussed each one in details. A comprehensive analysis in security aspects of MANET and defeating approaches is presented. In addition, defeating approaches against attacks have been evaluated in some important metrics. After analyses and evaluations, future scopes of work have been presented.

description: We exploit the recently developed software package LieART to show that SU(N) grand unified theories with chiral fermions in mixed tensor irreducible representations can lead to standard model chiral fermions without additional light exotic chiral fermions, i.e., only standard model fermions are light in these models. Results are tabulated which may be of use to model builders in the future. An SU(6) toy model is given and model searches are discussed.

description: PURPOSE. To characterize the chemokines and chemokine receptors that mediate the effect of proinflammatory cytokines, interleukin (IL)-1 and tumor necrosis factor (TNF)-α, on the recruitment of MHC class II+Langerhans cells (LCs) in the corneal epithelium. METHODS. A standard model for corneal LC recruitment, application of cautery to the central corneal surface was used, and the differential gene expression levels of a panel of chemokines and chemokine receptors were determined by RNase protection assay. Chemokine receptor-knockout mice were used to evaluate the recruitment of MHC class II+LCs to the corneal epithelium. To determine the sensitivity of selected chemokines to IL-1 and TNF-a stimulation, the chemokine gene expression pattern was analyzed after blockade of IL-1 and TNF receptors. RESULTS. CCR1, -2, and -5 were overexpressed in corneas after cauterization. Topical administration of soluble TNF receptor I and IL-1 receptor antagonist, which abrogated corneal LC recruitment, significantly suppressed the gene transcription levels of the ligands of CCR1 and/or -5, regulated on activation normal T-cell expressed and secreted (RANTES), macrophage inflammatory protein (MIP)-1α, and MIP-1β. The recruitment of major histocompatibility complex (MHC) class II+LC was significantly suppressed in CCR5-/-mice and blockade of RANTES and MIP-1β, but not in CCRI-/-, CCR2-/-/MIP-1α-/-, or MIP-1α-/-mice. The evaluation of epithelial CD11c+LC cells by confocal microscopy revealed coexpression for CCR5 primarily among B7-(CD80-/CD86 ) subsets of these LCs but not among the mature B7+subsets of CD1 1c+LCs. CONCLUSIONS. These data suggest that CCR5 plays a critical role in mediating recruitment and mobilization of MHC class II+LCs into the corneal epithelium. Targeting CCR5 and its ligands may be a new strategy for modulating immunity.

description: PURPOSE. To develop a sensitive psychophysical test for detecting visual defects such as microscotomas. METHODS. Frequency-of-seeing curves were measured with 0.75' and 7.5' spots. On each trial, from 0 to 4 stimuli were randomly presented at any of eight equally spaced loci 0.5° from fixation. By correcting the aberrations of the eye, adaptive optics produced retinal images of the 0.75' spot that were 3.0 μm wide at half height, small enough to be almost entirely confined within the typical cone diameter at this eccentricity. Data were collected from a patient with deuteranopia (AOS1) whose retina, imaged with adaptive optics, suggested that ≈30% of his cones were missing or abnormal. Patients with protanomalous trichromacy (1 subject), deuteranopia (1 subject), and trichromacy (5 subjects) served as controls (all had normal cone density and complete cone mosaics). Psychophysical results were modeled by a Monte Carlo simulation incorporating measured properties of the cone mosaic. RESULTS. Frequency-of-seeing curves for AOS1 obtained with 0.75' spots showed lower asymptote, slope, and sensitivity than for controls. The 7.5' results showed that these differences were the result of the small spot size, which on some trials was confined mostly to the locus of the putatively missing cones. A two-parameter model satisfactorily described the data and was highly sensitive to the proportion of missing cones simulated. CONCLUSIONS. Adaptive-optics microperimetry is a powerful psychophysical test for assessing the loss of neural elements, even in retinas that appear otherwise normal in standard clinical tests. This technique may prove useful in estimating the proportion of missing cones in different patients and in detecting other visual losses such as those associated with glaucoma.

description: Progress in urban climate science is severely restricted by the lack of useful information that describes aspects of the form and function of cities at a detailed spatial resolution. To overcome this shortcoming we are initiating an international effort to develop the World Urban Database and Access Portal Tools (WUDAPT) to gather and disseminate this information in a consistent manner for urban areas worldwide. The first step in developing WUDAPT is a description of cities based on the Local Climate Zone (LCZ) scheme, which classifies natural and urban landscapes into categories based on climate-relevant surface properties. This methodology provides a culturally-neutral framework for collecting information about the internal physical structure of cities. Moreover, studies have shown that remote sensing data can be used for supervised LCZ mapping. Mapping of LCZs is complicated because similar LCZs in different regions have dissimilar spectral properties due to differences in vegetation, building materials and other variations in cultural and physical environmental factors. The WUDAPT protocol developed here provides an easy to understand workflow; uses freely available data and software; and can be applied by someone without specialist knowledge in spatial analysis or urban climate science. The paper also provides an example use of the WUDAPT project results.

description: This paper explores how farmers self-select into irrigation farming ecosystem, and describe their characteristics and effects on Collective Actions (CA) management in irrigation systems. The study sampled seven irrigation schemes; both traditional improved and modern ones located in the Lake Victoria basin, namely Mahiga irrigation scheme (Ngudu), Igongwa (Misungwi), Nyida (Shinyanga rural), Maliwanda and Nyatwali (Bunda), Cheleche and Irienyi (Rorya). Cross sectional research design is employed to collect data from a total of 184 randomly sampled farm households involved in rice irrigation farming. Collected data are analyzed using Heckman two step procedures to identify self-selection factors. The inverse mills ratio result from the Heckman model is positive and significant at less than 5 % level, confirming the evidence for the presence of self-selection for the sampled farmers. Factors like large number of household labour force; non tangible benefits like reciprocated information sharing and use of CA association as a bridge to access support; good working rules in the group; net area sown; trust in group members and leaders; irrigation position; respect of public services provision /contributions; dodging contributions; violation of rules are important determinants of self-selection, each with specific implication that impact positively or negatively on CA survival. The study concludes that irrigation farming ecosystem choice is a non-random choice, and hence selection of members for organized CA establishment should base on factors described above, which significantly impacted positively self-selection into treatment (irrigation ecosystem type).

description: We use the Arepo moving mesh code to simulate the evolution of molecular clouds exposed to a harsh environment similar to that found in the galactic center (GC), in an effort to understand why the star formation efficiency (SFE) of clouds in this environment is so small. Our simulations include a simplified treatment of time-dependent chemistry and account for the highly non-isothermal nature of the gas and the dust. We model clouds with a total mass of 1.3x10^5 M_{sun} and explore the effects of varying the mean cloud density and the virial parameter, alpha = E_{kin}/|E_{pot}|. We vary the latter from alpha = 0.5 to alpha = 8.0, and so many of the clouds that we simulate are gravitationally unbound. We expose our model clouds to an interstellar radiation field (ISRF) and cosmic ray flux (CRF) that are both a factor of 1000 higher than the values found in the solar neighbourhood. As a reference, we also run simulations with local solar neighbourhood values of the ISRF and the CRF in order to better constrain the effects of the extreme conditions in the GC on the SFE. Despite the harsh environment and the large turbulent velocity dispersions adopted, we find that all of the simulated clouds form stars within less than a gravitational free-fall time. Increasing the virial parameter from alpha = 0.5 to alpha = 8.0 decreases the SFE by a factor ~4-10, while increasing the ISRF/CRF by a factor of 1000 decreases the SFE again by a factor ~2-6. However, even in our most unbound clouds, the SFE remains higher than that inferred for real GC clouds. We therefore conclude that high levels of turbulence and strong external heating are not enough by themselves to lead to a persistently low SFE at the center of the Galaxy.

description: IMPORTANCE: Isotretinoin is the most effective treatment for acne. The ideal dosing regimen is unknown.

OBJECTIVE: To determine the rates of relapse of acne vulgaris and retrial of isotretinoin after high cumulative-dose treatment and the changes to the adverse effect profile.

DESIGN, SETTING, AND PARTICIPANTS: A prospective, observational, intervention study was conducted from August 1, 2008, to August 31, 2010, in a single academic tertiary care center with multiple providers. A total of 180 patients with acne resistant to other treatments were enrolled. Of these, 116 participated in the 12-month follow-up survey, for a response rate of 64.4%.

EXPOSURE: Patients received isotretinoin, with dosing based on the providers' judgment. Patients were divided into 2 groups on the basis of cumulative dosing (<220 mg/kg and ≥ 220 mg/kg).

MAIN OUTCOMES AND MEASURES: Relapse (treatment with a prescription topical or oral acne medication after a course of isotretinoin) or retrial (retreatment with isotretinoin) at 12-month follow-up and adverse effects experienced during and after 12 months of treatment. RESULTS The mean age of the participants was 19.3 years, 51.9% were female, and 74.1% were white. At 12 months' follow-up, 97.4% of the patients reported that their acne was improved. Overall, acne in 32.7% of patients in the study relapsed at 12 months, and 1.72% of the patients required a retrial. In the lower-dose treatment group (<220 mg/kg), the relapse rate was 47.4% (95% CI, 32.3%-63.0%) compared with 26.9% (95% CI, 18.3%-37.8%) in the high-dose group (P = .03). Almost 100% of the patients in both treatment groups developed cheilitis and xerosis during treatment. Retinoid dermatitis was significantly more common in the high-dose treatment group (53.8% vs 31.6%; P = .02). None of the other adverse effects was significantly different between the 2 groups.

CONCLUSIONS AND RELEVANCE: The dosing regimen used in the present study is considerably higher than that used in previous studies of isotretinoin. At 1 year after completion of isotretinoin treatment, we found that patients receiving 220 mg/kg or more had a significantly decreased risk of relapse. Rash was the only adverse effect that was significantly more common in the high-dose group during treatment. This study suggests that significantly higher doses of isotretinoin are effective for treating acne and decreasing relapse rates without increasing adverse effects.

description: IMPORTANCE: The absence of data on the prevalence of pilomatricoma among patients with Turner syndrome served as the catalyst for this multicenter investigation.

OBJECTIVES: To ascertain the prevalence of pilomatricoma among patients with Turner syndrome and to determine any association between the development of pilomatricomas and the use of exogenous hormones in patients with Turner syndrome.

DESIGN: A retrospective medical record review from January 1, 2000, through January 1, 2010, was performed of all patients with Turner syndrome. Data on pilomatricomas and the use of hormone therapy were collected.

SETTING: University of California-Davis Medical Center, University of Nebraska Medical Center, and The University of North Carolina at Chapel Hill.

PARTICIPANTS: Patients with a diagnosis of Turner syndrome.

MAIN OUTCOME MEASURES: Prevalence of concomitant pilomatricoma and diagnosis of Turner syndrome. Secondary outcome measures included the use of the exogenous hormones estrogen or recombinant human growth hormone (rhGH).

RESULTS: In total, 311 patients with Turner syndrome were identified from these 3 institutions. Among them, 8 patients (2.6%) were diagnosed as having pilomatricomas. Before the development of pilomatricomas, 5 patients had been treated with rhGH but not estrogen, 1 patient had received estrogen but not rhGH, and 2 patients did not receive either therapy.

CONCLUSIONS AND RELEVANCE: Although the prevalence of pilomatricoma among the general population is unknown, this study demonstrates a high prevalence (2.6%) of pilomatricomas among patients with Turner syndrome. No apparent relationship was noted among our patients or in the literature between the use of rhGH and the development of pilomatricomas.

description: The success of topological insulators (TI) in creating devices with unique functionalities is directly connected to the ability of coupling their helical spin states to well defined perturbations. However, up to now, TI-based heterostructures always resulted in very disordered interfaces, characterized by strong mesoscopic fluctuations of the chemical potential which make the spin-momentum locking ill-defined over length scales of few nanometers or even completely destroy topological states. These limitations call for the ability to control topological interfaces with atomic precision. Here, we demonstrate that molecular self-assembly processes driven by inherent interactions among the constituents offer the opportunity to create well-defined networks at TIs surfaces. Even more remarkably, we show that the symmetry of the overlayer can be finely controlled by appropriate chemical modifications. By analyzing the influence of the molecules on the TI electronic properties, we rationalize our results in terms of the charge redistribution taking place at the interface. Overall, our approach offers a precise and fast way to produce tailor-made nanoscale surface landscapes. In particular, our findings make organic materials ideal TIs counterparts, since they offer the possibility to chemically tune both electronic and magnetic properties within the same family of molecules, thereby bringing us a significant step closer towards an application of this fascinating class of materials.

description: Kapteyn's star is an old M subdwarf believed to be a member of the Galactic halo population of stars. A recent study has claimed the existence of two super-Earth planets around the star based on radial velocity (RV) observations. The innermost of these candidate planets--Kapteyn b (P = 48 days)--resides within the circumstellar habitable zone. Given recent progress in understanding the impact of stellar activity in detecting planetary signals, we have analyzed the observed HARPS data for signatures of stellar activity. We find that while Kapteyn's star is photometrically very stable, a suite of spectral activity indices reveals a large-amplitude rotation signal, and we determine the stellar rotation period to be 143 days. The spectral activity tracers are strongly correlated with the purported RV signal of "planet b," and the 48-day period is an integer fraction (1/3) of the stellar rotation period. We conclude that Kapteyn b is not a planet in the Habitable Zone, but an artifact of stellar activity.

description: IMPORTANCE: Strong links between indoor tanning behavior and skin cancer have been demonstrated across several studies. Understanding the complex belief systems that underlie indoor tanning in young women is a crucial first step in developing interventions to deter this behavior.

OBJECTIVES: To develop and validate a comprehensive, multidimensional, theory-based outcome expectations measure to advance an understanding of the sets of beliefs that underlie indoor tanning behavior among young women.

DESIGN, SETTING, AND PARTICIPANTS: Cross-sectional study comprising a web-based survey of 11 sororities at a large university in the southeastern United States. Study participants (n = 706) were aged 18 to 25 years; 45.3% had tanned indoors in their lifetime and 30.3% in the past year.

MAIN OUTCOMES AND MEASURES: Intention to tan indoors, frequency of indoor tanning behavior in the past year, and indoor tanner type (nontanner, former tanner, or current tanner).

RESULTS: A comprehensive scale assessing indoor tanning outcome expectations was developed. In total, 6 positive outcome expectations factors and 5 negative outcome expectations factors were identified. These subscales were reliable (coefficient α range, 0.86-0.95) and were significantly (mostly at P < .001) correlated with a set of established measures, including appearance motivation, indoor tanning attitudes and norms, and intention to tan indoors. Examination of subscales across the 3 indoor tanning groups also revealed significant (P < .001) differences on all 11 subscales. Current tanners had the most positive and least negative perceptions about indoor tanning, while nontanners had the most negative and least positive perceptions. Former tanners tended to fall in between these 2 groups. The 2 subscales with the largest differences across the groups were mood enhancement (positive outcome expectation) and psychological/physical discomfort (negative outcome expectation). Multiple linear regression analyses demonstrated several outcome expectations subscales to be significantly associated with intention to tan indoors and frequency of indoor tanning behavior.

CONCLUSIONS AND RELEVANCE: Results suggest that the Comprehensive Indoor Tanning Expectations (CITE) Scale provides a reliable and valid assessment of the complex sets of beliefs that underlie indoor tanning, including positive (motivational) and negative (deterrent) beliefs. This new scale may further advance research on indoor tanning beliefs and can guide health communications to prevent and deter indoor tanning behavior.

Overview

Tras las paredes de un elegante rascacielos de cuarenta pisos a las afueras de Londres (el primero habitado de cinco edificios iguales) sus dos mil inquilinos se entregan a una orgía de destrucción.

description: IMPORTANCE The common practices used in the perioperative care of patients undergoing septorhinoplasty are diverse and controversial. A consensus statement on the preferred clinical pathway in the perioperative treatment of patients undergoing septorhinoplasty has yet to be approached formally. OBJECTIVES To investigate the perioperative treatment of patients undergoing septorhinoplasty and to identify common practice patterns based on the preferences of leading facial plastic surgeons. DESIGN, SETTING, AND PARTICIPANTS We distributed an online survey to members of the American Academy of Facial Plastic and Reconstructive Surgery. Specifically, fellowship directors and academic contact members were anonymously polled and stratified by the number of septorhinoplasties performed annually. MAIN OUTCOME AND MEASURE A cohesive clinical guide to perioperative treatment after rhinoplasty. RESULTS Of the 92 members surveyed, 67 (73%) successfully completed the survey. The distribution of respondents included 43 academicians (64%) and 24 physicians in private practice (36%). Twenty-eight surgeons (42%) performed fewer than 50 rhinoplasties a year and 39 (58%), more than 50, representing 3510 to 4549 septorhinoplasties in total among respondents. Forty-four surgeons (66%) refrained from using any packing, and 41 (61%) used intranasal splints, with polymeric silicone splints the most popular of these (n = 24 [59%]). Sixty-six surgeons (99%) used external nasal splints, including 49 (74%) who used a thermoplastic splint and 49 (74%) who left the external nasal splint in place for 7 days or longer. The most common postoperative interventions to reduce edema and ecchymosis were elevation of the head of bed by 62 (93%), ice packs by 50 (75%), and Arnica montana by 33 (49%). Only 12 surgeons (18%) used postoperative corticosteroids to reduce edema. Fifty-six respondents (84%) prohibited participation in contact sports until at least 6 weeks after surgery. CONCLUSIONS AND RELEVANCE Perioperative care and practices after nasal surgery vary among the most highly trained and leading rhinoplasty surgeons. No published communication or consensus on perioperative practices has been disseminated in this setting. Given the results from those surgeons performing the most rhinoplasties in our field, some surgeons may choose to vary their practices to coincide with those of experienced surgeons. These guidelines could facilitate future studies of patient outcomes.

description: We derive a general scaling relation for the anomalous Hall effect in ferromagnetic metals involving multiple competing scattering mechanisms, described by a quadratic hypersurface in the space spanned by the partial resistivities. We also present experimental findings, which show strong deviation from previously found scaling forms when different scattering mechanism compete in strength but can be nicely explained by our theory.

Overview

Pelea de gallos narra desde diferentes voces el hogar, ese espacio que construye ?odestruye? a las personas, aborda los vínculos familiares y sus códigos secretos, las relaciones de poder, el afecto, los silencios, la solidaridad, el abuso... Es decir, todos los horrores y maravillas que se encierran entre las cuatro paredes de una casa: el espanto y la gloria de nuestras vidas cotidianas.María Fernanda Ampuero ha reunido en su primer libro de cuentos a un buen número de seres inocentes que se corrompen, gente enferma de amor, de soledad, de pérdida?personas que luchan, a su manera, contra la nítida crueldad de estar vivos? y lo hace con un libro demoledor y apegado a Latinoamérica, en cuyas páginas se van desgranando elementos culturales, políticos y sociales que retratan a un continente en su complejidad, en sus radicales diferencias y semejanzas.

description: IMPORTANCE The transition from pediatric to adult health care is a vulnerable time for patients with chronic conditions. We need to better understand the factors affecting the health of kidney transplant recipients during this transition. OBJECTIVE To determine the age at which renal transplant recipients are at greatest risk for graft loss. DESIGN, SETTING, AND PARTICIPANTS We performed a retrospective analysis of 168 809 first kidney-only transplant events from October 1987 through October 2010, in recipients up to age 55 years as reported by the Organ Procurement Transplantation Network Standard Transplant Analysis and Research Database. Recipient age at transplant was the primary predictor studied. Confounder and effect modifier covariates were identified and studied using Cox proportional hazard models. EXPOSURE Kidney-only transplant. MAIN OUTCOMES AND MEASURES Patient and renal graft survival, along with death-censored and non―death-censored information. RESULTS A total of 168 809 renal transplant events met the inclusion criteria. Recipients who received their first kidney transplant at age 14 to 16 years were at the highest risk of graft loss, with inferior outcomes starting at 1 and amplifying at 3, 5, and 10 years after transplant. Black adolescents were at disproportionately high risk of graft failure. The variables that had significant interaction with recipient age were donor type (deceased vs living) and insurance type (government vs private). Among 14-year-old recipients, the risk of death was 175% greater in the deceased donor-government insurance group vs the living donor―private insurance group (hazard ratio, 0.92 [95% CI, 0.90-0.94] vs 0.34 [95% CI, 0.33-0.36]), whereas patient survival rates in the living donor―government insurance and deceased donor―private insurance groups were nearly identical (hazard ratio, 0.61 [95% CI, 0.58-0.63] vs 0.54 [95% CI, 0.51-0.56]). CONCLUSIONS AND RELEVANCE Recipients aged 14 to 16 years have the greatest risk of kidney allograft failure. Black adolescents and those with government insurance are at even higher risk. Private insurance reduces risk of death across all ages. Comprehensive programs are needed for adolescents, especially for those at greater risk, to reduce graft loss during the transition from adolescence to adulthood.

description: Randomly crumpled sheets have shape memory. In order to understand the basis of this form of memory, we simulate triangular lattices of springs whose lengths are altered to create a topography with multiple potential energy minima. We then deform these lattices into different shapes and investigate their ability to retain the imposed shape when the energy is relaxed. The lattices are able to retain a range of curvatures. Under moderate forcing from a state of local equilibrium, the lattices deform by several percent but return to their retained shape when the forces are removed. By increasing the forcing until an irreversible motion occurs, we find that the transitions between remembered shapes show co-operativity among several springs. For fixed lattice structures, the shape memory tends to decrease as the lattice is enlarged; we propose ways to counter this decrease by modifying the lattice geometry. We survey the energy landscape by displacing individual nodes. An extensive fraction of these nodes proves to be bistable; they retain their displaced position when the energy is relaxed. Bending the lattice to a stable curved state alters the pattern of bistable nodes. We discuss this shapeability in the context of other forms of material memory and contrast it with the shapeability of plastic deformation. We outline the prospects for making real materials based on these principles.

description: IMPORTANCE: Comparative effectiveness research of prostate cancer therapies is needed because of the development and rapid clinical adoption of newer and costlier treatments without proven clinical benefit. Radiotherapy is indicated after prostatectomy in select patients who have adverse pathologic features and in those with recurrent disease.

OBJECTIVES: To examine the patterns of use of intensity-modulated radiotherapy (IMRT), a newer, more expensive technology that may reduce radiation dose to adjacent organs compared with the older conformal radiotherapy (CRT) in the postprostatectomy setting, and to compare disease control and morbidity outcomes of these treatments.

DESIGN AND SETTING: Data from the Surveillance, Epidemiology, and End Results-Medicare-linked database were used to identify patients with a diagnosis of prostate cancer who had received radiotherapy within 3 years after prostatectomy.

PARTICIPANTS: Patients who received IMRT or CRT.

MAIN OUTCOMES AND MEASURES: The outcomes of 457 IMRT and 557 CRT patients who received radiotherapy between 2002 and 2007 were compared using their claims through 2009. We used propensity score methods to balance baseline characteristics and estimate adjusted incidence rate ratios (RRs) and their 95% CIs for measured outcomes.

RESULTS: Use of IMRT increased from zero in 2000 to 82.1% in 2009. Men who received IMRT vs CRT showed no significant difference in rates of long-term gastrointestinal morbidity (RR, 0.95; 95% CI, 0.66-1.37), urinary nonincontinent morbidity (0.93; 0.66-1.33), urinary incontinence (0.98; 0.71-1.35), or erectile dysfunction (0.85; 0.61-1.19). There was no significant difference in subsequent treatment for recurrent disease (RR, 1.31; 95% CI, 0.90-1.92).

CONCLUSIONS AND RELEVANCE: Postprostatectomy IMRT and CRT achieved similar morbidity and cancer control outcomes. The potential clinical benefit of IMRT in this setting is unclear. Given that IMRT is more expensive, its use for postprostatectomy radiotherapy may not be cost-effective compared with CRT, although formal analysis is needed.
