Mapping Urban Impervious Surface by Fusing Optical and SAR Data at the Decision Level
Authors: Shao Zhenfeng , Fu Huyan , Fu Peng , Yin Li
Published: November 2016

The proliferation of impervious surfaces results in a series of environmental issues, such as the decrease of vegetated areas and the aggravation of the urban heat island effects. The mapping of impervious surface and its spatial distributions is of significance for the ecological study of urban environment. Currently, the integration of optical and synthetic aperture radar (SAR) data has shown advantages in accurately characterizing impervious surface. However, the fusion mainly occurs at the pixel and feature levels which are subject to influences of data noises and feature selections, respectively. In this paper, an innovative and effective method was developed to extract urban impervious surface by synergistically utilizing optical and SAR images at the decision level. The objective of this paper was to obtain an accurate urban impervious surface map based on the random forest classifier and the evidence theory and to provide a detailed uncertainty analysis accompanying the fused impervious surface maps. In this study, both the GaoFen (GF-1) and Sentinel-1A imagery were first used as independent data sources for mapping urban impervious surfaces. Then additional spectral features and texture features were extracted and integrated with the original GF-1 and Sentinel-1A images in generating impervious surfaces. Finally, based on the Dempster-Shafer (D-S) theory, impervious surfaces were produced by fusing the previously estimated impervious surfaces from different datasets at the decision level. Results showed that impervious surfaces estimated from the combined use of original images and features yielded a higher accuracy than those from the original optical or SAR data. Further validations suggested that optical data was better than SAR data in separating impervious surfaces from non-impervious surfaces. The fused impervious surfaces at the decision level had a higher overall accuracy than those produced independently by optical or SAR data. It was also highlighted that the fusion of GF-1 and Sentinel-1A images reduced the amount of confusions among the low reflectance of impervious surface and water, as well as for low reflectance of bare land. An overall accuracy of 95.33% was achieved for extracting urban impervious surfaces by fused datasets. The spatial distributions of uncertainties provided by the evidence theory displayed a confidence level of at least 75% for the impervious surfaces derived from the fused datasets.

Published: November 2016

The production of a nanomaterial with enhanced and desirable electrocatalytic properties is of prime importance, and the commercialization of devices containing these materials is a challenging task. In this study, unique cupric oxide (CuO) nanostructures were synthesized using lysine as a soft template for the evolution of morphology via a rapid and boiled hydrothermal method. The morphology and structure of the synthesized CuO nanomaterial were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD), respectively. The prepared CuO nanostructures showed high potential for use in the electrocatalytic oxidation of glucose in an alkaline medium. The proposed enzyme-free glucose sensor demonstrated a robust response to glucose with a wide linear range and high sensitivity, selectivity, stability, and reproducibility. To explore its practical feasibility, the glucose content of serum samples was successfully determined using the enzyme-free sensor. An analytical recovery method was used to measure the actual glucose from the serum samples, and the results were satisfactory. Moreover, the presented glucose sensor has high chemical stability and can be reused for repetitive measurements. This study introduces an enzyme-free glucose sensor as an alternative tool for clinical glucose quantification.
Secure Multiuser Communications in Wireless Sensor Networks with TAS and Cooperative Jamming

Published: November 2016

In this paper, we investigate the secure transmission in wireless sensor networks (WSNs) consisting of one multiple-antenna base station (BS), multiple single-antenna legitimate users, one single-antenna eavesdropper and one multiple-antenna cooperative jammer. In an effort to reduce the scheduling complexity and extend the battery lifetime of the sensor nodes, the switch-and-stay combining (SSC) scheduling scheme is exploited over the sensor nodes. Meanwhile, transmit antenna selection (TAS) is employed at the BS and cooperative jamming (CJ) is adopted at the jammer node, aiming at achieving a satisfactory secrecy performance. Moreover, depending on whether the jammer node has the global channel state information (CSI) of both the legitimate channel and the eavesdropper’s channel, it explores a zero-forcing beamforming (ZFB) scheme or a null-space artificial noise (NAN) scheme to confound the eavesdropper while avoiding the interference to the legitimate user. Building on this, we propose two novel hybrid secure transmission schemes, termed TAS-SSC-ZFB and TAS-SSC-NAN, for WSNs. We then derive the exact closed-form expressions for the secrecy outage probability and the effective secrecy throughput of both schemes to characterize the secrecy performance. Using these closed-form expressions, we further determine the optimal switching threshold and obtain the optimal power allocation factor between the BS and jammer node for both schemes to minimize the secrecy outage probability, while the optimal secrecy rate is decided to maximize the effective secrecy throughput for both schemes. Numerical results are provided to verify the theoretical analysis and illustrate the impact of key system parameters on the secrecy performance.
On the Acceptance and Sustainability of Renewable Energy Projects—A Systems Thinking Perspective
Authors: González Ana , Sandoval Harrison , Acosta Pilar , Henao Felipe
Published: November 2016

Rapid population growth and increasing concern related to improving the living standards in impoverished communities without damaging the natural environment have drawn attention to the adoption of renewable energy systems (RES) around the world. Despite this global trend, the implementation of these projects has not succeeded completely in rural poor communities due to several factors, including social barriers faced at the time of their execution. These social barriers lead to poor acceptance of the projects and their consequent abandonment. Acceptance is a social construct that is influenced by several factors that need to be understood to achieve successful and sustainable results in the future. In this paper, we develop a conceptual model, based on principles of sustainability and systems thinking, to understand the interrelationships among the main factors that have been reported in the literature as key to determining the sustainability and community acceptance of RES projects. To do so, we review the existing literature on sustainability and social acceptance of RES and then construct a causal-loop diagram of their driving factors. While doing so, we also view the problem through the lens of the sustainable livelihoods framework, aiming to maintain the perspective of rural communities and observing the impacts of RES on their contextual reality. The resulting model helps to understand the multiple interactions that RES projects have with rural communities as well as identify potential intervention points for future projects. We end the paper with a discussion of the implications of the model and how can it be used to inform future rural energy decision making.

Published: November 2016

Ochratoxin A (OTA) contamination has been established as a world-wide problem. In this study, the strains with the ability of OTA production were screened by analyzing the green fluorescence of the isolates colonies from the grapes in Zhenjiang with 365 nm UV light and confirmed by HPLC with fluorescent detection (HPLC-FLD). The results showed that seven isolates acquired the characteristic of the fluorescence, of which only five showed the ability of OTA production as confirmed by HPLC-FLD analysis. The five OTA-producing strains were identified based on comparative sequence analysis of three conserved genes (ITS, BenA and RPB2) of the strains, and they are Talaromyces rugulosus (O1 and Q3), Penicillium commune (V5-1), Penicillium rubens (MQ-5) and Aspergillus aculeatus (MB1-1). There are two Penicillium species of the five OTA-producing strains and our study is the first to report that P. rubens, T. rugulosus and A. aculeatus can produce OTA. This work would contribute to comprehensively understanding the fungi with an OTA-producing ability in grapes before harvest and then take effective measures to prevent OTA production.
The Impact of Chemotherapy, Radiation and Epigenetic Modifiers in Cancer Cell Expression of Immune Inhibitory and Stimulatory Molecules and Anti-Tumor Efficacy
Authors: Chacon Jessica , Schutsky Keith , Powell Daniel
Published: November 2016

Genomic destabilizers, such as radiation and chemotherapy, and epigenetic modifiers are used for the treatment of cancer due to their apoptotic effects on the aberrant cells. However, these therapies may also induce widespread changes within the immune system and cancer cells, which may enable tumors to avoid immune surveillance and escape from host anti-tumor immunity. Genomic destabilizers can induce immunogenic death of tumor cells, but also induce upregulation of immune inhibitory ligands on drug-resistant cells, resulting in tumor progression. While administration of immunomodulatory antibodies that block the interactions between inhibitory receptors on immune cells and their ligands on tumor cells can mediate cancer regression in a subset of treated patients, it is crucial to understand how genomic destabilizers alter the immune system and malignant cells, including which inhibitory molecules, receptors and/or ligands are upregulated in response to genotoxic stress. Knowledge gained in this area will aid in the rational design of trials that combine genomic destabilizers, epigenetic modifiers and immunotherapeutic agents that may be synergized to improve clinical responses and prevent tumor escape from the immune system. Our review article describes the impact genomic destabilizers, such as radiation and chemotherapy, and epigenetic modifiers have on anti-tumor immunity and the tumor microenvironment. Although genomic destabilizers cause DNA damage on cancer cells, these therapies can also have diverse effects on the immune system, promote immunogenic cell death or survival and alter the cancer cell expression of immune inhibitor molecules.
Effect of Slope, Rainfall Intensity and Mulch on Erosion and Infiltration under Simulated Rain on Purple Soil of South-Western Sichuan Province, China

Published: November 2016

Purple soil is widely distributed in the hilly areas of the Sichuan basin, southwest China, and is highly susceptible to water erosion. The triggering of this process is related to slope, rainfall intensity and surface cover. Therefore, this study assesses the effects of different simulated rainfall intensities with different slopes on hydrological and erosional processes in un-mulched and mulched purple soils. Results show that the sediment and water losses increased with an increase of rainfall intensity and slope steepness. Generally, the slope contribution (Sc) on water and sediment losses decreased with increasing rainfall intensity and slope steepness under both un-mulched and mulched soil. In un-mulched conditions, water losses were independent of slope steepness (Sc < 50%) during the highest rainfall intensity. However, in mulched soil, the higher contributions of slope (Sc) and rainfall (Rc) were found for water and sediment losses, respectively, i.e., >50%, except during the increase in slope steepness from 15° to 25° under the highest rainfall intensity (120 mm·h−1). The effectiveness of mulch was more pronounced in reducing sediment losses (81%–100%) compared with water losses (14%–100%). The conservation effectiveness of mulch both decreased and increased with slope steepness for water and sediment losses, respectively, under higher rainfall intensities. Water infiltration and recharge coefficient (RC) decreased with an increase of slope steepness, while with an increase in rainfall intensity, the water infiltration and RC were increased and decreased, respectively, in both un-mulched and mulched soil. On the other hand, mulched soil maintained a significantly (α = 0.05) higher infiltration capacity and RC compared to that of the un-mulched soil.
THE IMPACT OF UNRESOLVED TURBULENCE ON THE ESCAPE FRACTION OF LYMAN CONTINUUM PHOTONS

Published: November 2016

We investigate the relation between the turbulent Mach number (

. At a fixed Mach number, the correction factor for escape fraction relative to a constant column density case scales exponentially with the opacity in the cell, which has a large impact for simulated star-forming regions. Furthermore, in simulations of isotropic turbulence with full atomic/ionic cooling and chemistry, the fraction of HI drops by a factor of

at Mach numbers above 10. Such Mach numbers are common at high redshifts where vigorous turbulence is driven by supernovae, gravitational instabilities, and merger activity, as shown both by numerical simulations and observations. These results, if implemented in the current hydrodynamical cosmological simulations to account for unresolved turbulence, can boost the theoretical predictions of the Lyman Continuum photon escape fraction and further constrain the sources of reionization.

Published: November 2016

The authors reviewed the files of all patients with chordomas who were admitted and treated at their institutions from 1975 to 2012. Patients were categorized by early local recurrence and metastasis. Aggressive clinical behavior was defined as local recurrence and metastasis within 24 months of diagnosis and adequate treatment (wide en bloc resection with microscopically negative tumor margins). According to these criteria, 13 patients (14.3%) had aggressive chordomas, including 7 men and 6 women, with mean age of 54 years (range, 37–65 years) at diagnosis and treatment. All patients had preoperative tumor biopsy, followed by resection with partial (7 patients) or total sacrectomy (6 patients). In all cases, biopsy and histologic analysis of resected tumor specimens showed conventional chordomas. Resection margins were wide (grossly negative) in 6 patients and wide contaminated in 7 patients. Mean maximum tumor diameter was 11.8 cm (range, 5–21 cm). Mean follow-up was 43 months (range, 8–131 months). Rates of local recurrence, metastasis, and death were evaluated. At the last follow-up, all patients had local recurrence at a mean of 13 months (range, 5–22 months). Histologic examination of recurrent tumors showed a dedifferentiated chordoma with a fibrosarcoma component in 2 patients and no histologic change in the remaining patients. In addition, 8 patients had metastases at a mean of 13 months (range, 4–24 months) and died of their disease. All histologic findings of metastatic lesions were similar to those of primary tumors. Early diagnosis of aggressive tumors requires close follow-up of patients with chordomas. Metastasis is common, with resultant poor survival. [

Published: November 2016

Accurate sagittal alignment of the femoral component in total knee arthroplasty is crucial for prosthesis longevity, improved function, and patient satisfaction. However, there is variation in the techniques used to attain optimal sagittal femoral component placement in total knee arthroplasty. Femoral component flexion in imageless navigation is based on the mechanical axis rather than the distal femoral anatomy, and there is significant variability in the anatomy of the distal femur. The purpose of this study was to accurately determine the mean distal femoral flexion angle of a representative population and whether variability of the distal femoral flexion angle correlates with race, femur length, or radius of curvature. The mean degree of distal femoral flexion was determined by assessing distal femoral anatomy on computed tomography scans of paired femurs of 1235 patients without evidence of previous fracture, deformity, or surgical implants. The mean±SD distal femoral flexion angle was 2.90°±1.52°, with 80.2% of knees within 3°±2°. Therefore, placing the component in 3° of flexion from the mechanical axis would attain a satisfactory position in most cases. However, further analysis of the patient data revealed 11.4% of Asians, 7.3% of African Americans, and 8.3% of whites had a distal femoral flexion angle greater than 5°. Additionally, the data revealed a moderately strong negative correlation between the distal femoral flexion and the overall radius of curvature of the femur. This preliminary study highlights the need for improved methods for selecting femoral component position in the sagittal plane when using navigation for total knee arthroplasty.

Emergency Department Triage of the “Incessantly Crying” Baby
Authors: Chua Caroline , Setlik Jennifer , Niklas Victoria
Published: November 2016

Incessant crying is one of the most common caregiver complaints during emergency department (ED) visits in the first few months of the child's life. Although the majority of cases are attributed to normal infant behavior, the differential diagnosis remains broad. Moreover, the potential for the negative impact of incessant crying on the mental well-being of caregivers as well as the infants necessitates that complaints be taken seriously and that “red flags” for underlying organic causes be ruled out and caregiver anxiety quelled. In addition, the apparent triviality of incessant crying in the face of the life-threatening illnesses or injuries that confront practitioners in the ED necessitates a high level of due diligence in the evaluation of these infants and their families. Ensuring the availability of family support is essential in the discharge planning. Families should also perceive the empathy of the physician and feel reassured about their safe discharge home. Although it is a challenge to examine an incessantly crying infant in all care settings, the failure to recognize the small percentage of infants that present with incessant crying as a manifestation of an underlying organic illness may have grave consequences.

Difficulties in the Diagnosis and Management of Functional or Recurrent Abdominal Pain in Children
Authors: Gomez-Suarez Roberto
Published: November 2016

Recurrent abdominal pain is a frequent pathology seen in the pediatric gastroenterology practice. In fact, most children with abdominal pain symptoms have functional disorders of the gastrointestinal tract. A focused medical history, comprehensive physical examination, and minimal testing are often enough to establish the diagnosis. The presence of red flags such as rectal bleeding, bilious vomiting, fever, and arthralgia should alert providers as well as direct further diagnostic and therapeutic plans. When patients show no red flags after a complete physical examination, providing the family with information about the pathophysiology and explaining the psychosocial model of pain can help to decrease anxiety around the pain symptoms. This article discusses the challenges in diagnosing and managing abdominal pain in children.

Fundus Autofluorescence Patterns of Submacular Fluid Resolution Following Repair of Macula-Involving Rhegmatogenous Retinal Detachments
Authors: Simonett Joseph M. , Grewal Dilraj S. , Fawzi Amani A. , Lyon Alice T. , Gill Manjot K.
Published: November 2016

BACKGROUND AND OBJECTIVE:

Submacular fluid (SMF) can persist for months to years following rhegmatogenous retinal detachment (RD) repair. The authors' objective was to describe fundus autofluorescence (FAF) and optical coherence tomography (OCT) findings associated with the absorption of persistent submacular fluid (SMF) following RD repair.

PATIENTS AND METHODS:

Retrospective review of clinical data and FAF and OCT imaging from sequential postoperative visits in a cohort of patients with persistent SMF following RD repair.

RESULTS:

In 11 of 13 eyes with persistent SMF, patches of decreased FAF signal corresponded to SMF on OCT. In eight eyes, there was a hypo- to hyperautofluorescence transition at the time of SMF resolution. These areas of increased FAF signal correlated with inner segment/outer segment (IS/OS) junction loss on OCT.

CONCLUSION:

FAF imaging can be informative when following SMF after RD repair; a hypo- to hyper-FAF signal transition correlates with SMF resolution and photoreceptor loss.

Optical Coherence Tomography Angiography Characteristics of Fovea in Residual Subfoveal Perfluorocarbon Liquid Eye
Authors: Wang Haiyan , Chen Fenge , Cao Hui
Published: November 2016

The authors report a case of optical coherence tomography angiography (OCTA) features of retina and choriocapillaris before and after the surgical removal of a subfoveal perfluorocarbon liquid (PFCL) bubble. Before the surgery, the fovea avascular zone (FAZ) of both superficial and deep inner retinal layers (SRL/DRL) dramatically enlarged. However, after the removal, the FAZ continually decreased in both layers, even becoming close to normal in size. The abnormal choriocapillaris dark areas were also undetectable. Before and after surgery, the angle of the maximum FAZ diameter constantly remained horizontal and within normal limit in the SRL, forming an oval-shaped FAZ.

Mizuo-Nakamura Phenomena
Authors: Mittal Kanhaiya , Chawla Rohan
Published: November 2016

A 21-year-old male presented with a chief complaint of night blindness since early childhood. The patient had no history of hemeralopia or photophobia, and no family history of such illness or use of glasses. On examination, his visual acuity was 6/6 in both eyes. Pupils were reacting normally. Dilated fundus examination revealed diffuse golden-yellow sheen throughout the fundus with prominent retinal vasculature, but arteries and veins were less distinguishable. Choroidal vessels were not visible. The patient was then patched and dark adapted for 6 hours. The dark-adapted fundus showed the disappearance of the golden sheen with normal visible choroidal and retinal vasculature. This characteristic phenomenon observed on fundus examination from dark-adapted state to light adaptation is known as Mizuo-Nakamura phenomenon. Although this phenomenon is classical of Oguchi disease, it is also seen in X-linked cone dystrophy and X-linked retinoschisis.

Las evidencias arqueológicas datan la expansión del cultivo de la vid en el territorio de Kelin durante los siglos V-III a. C., aunque los primeros indicios se fechan ya en el siglo VII a. C. Una de las singularidades de este territorio es la existencia de estructuras de piedra al aire libre para la producción de vino y aceite. Todas ellas se localizan en una zona concreta del territorio (Ramblas de la Alcantarilla y de los Morenos) (Requena, Valencia) y aparecen asociadas a materiales arqueológicos que permiten datarlas como ibéricas. En este artículo abordamos cómo se organiza el poblamiento en la rambla de la Alcantarilla y presentamos en detalle los yacimientos de la Rambla de la Alcantarilla y Solana de Cantos 2.

Del oppidum de Burriac a las termas de Ca l’Arnau. Una aproximación a la lengua y a la identidad de los habitantes de Ilduro (Cabrera de Mar, Barcelona)
Authors: Sinner Alejandro G. , Ferrer i Jané Joan
Published: November 2016

El análisis de los testimonios epigráficos de los yacimientos del valle de Cabrera de Mar muestra un dominio absoluto de la escritura ibérica sobre la latina, no sólo en el oppidum de Burriac, sino también en el asentamiento tardo-republicano situado en el actual casco urbano de Cabrera de Mar, ambos probablemente identificados con el topónimo ibérico Ilduro. Aunque la presencia en el asentamiento tardo-republicano de edificios públicos y privados de estilo itálico indican que su población se encuentra fuertemente influenciada por el estilo de vida y la cultura itálica, la presencia de inhumaciones de fetos humanos documentadas en niveles fundacionales y, especialmente, los documentos epigráficos, apuntan que incluso en el asentamiento tardo-republicano, el valle de Cabrera de Mar mantenía durante el s. II a. C. y hasta la primera mitad del s. I a. C. un marcado carácter ibérico.

Diode Laser Versus Scalpel in the Treatment of Hereditary Gingival Fibromatosis in a 6-Year Old Boy
Authors: Aboujaoude Samia , Cassia Antoine , Moukarzel Carla
Published: November 2016

Hereditary gingival fibromatosis (HGF) is a rare disease characterized by a benign enlargement of the gingiva involving both the mandible and the maxilla. This case is about a 6-year-old child with non syndromic HGF showing a severe gingival enlargement covering almost all surfaces of the teeth, in both arches, hence causing major aesthetic, phonetic and masticatory problems. The aim of the present article is to compare the outcomes of two therapeutical approaches: (i) classical surgical removal with scalpel; and (ii) diode laser resection. Compared to the surgical approach, the clinical results show that the main advantages of the diode laser technique are a better visibility during the intervention, minimal postoperative discomfort combined to a better gingival recontouring. However, the time consumption and the high cost of the laser equipment remain the main disadvantages of the systematic use of this technique.
Groundwater in Canada
Authors: Brown I C ,   Geological Survey of Canada
Published: November 2016

This report is the first detailed account of the occurrences, flow systems, and chemistry of groundwater in Canada. It relates the groundwater to the geological materials through which it flows and to the hydrologic cycle, and discusses comprehensively the
principles and methods of hydrogeology and the methods, techniques, and formulae required for aquifer exploration and development.
Canada contains six major hydrogeological regions. Much groundwater data are available for the Interior Plains and St. Lawrence Lowlands hydrogeological regions, where groundwater is used extensively. Less data are available for the Appalachian, Canadian Shield, and Cordilleran hydrogeological
regions, where surface waters are adequate to provide present demands. Little data are available for the northern region, where the population is sparsely distributed and permafrost influences the role of the groundwater.
Spruce tree chemistry to assist in geological mapping of an overburden-covered extensional fault, central British Columbia
Authors: Chan D , Struik L C
Published: November 2016

Biogeochemical surveys were conducted over a 150 km2 area near Weedon Lake during late spring of 1988 and 1989. Twigs of black spruce (Picea mariana) were collected in an area covered by glacial material and overlying a fault zone - the Weedon Fault - which
juxtaposes Triassic basalt with Mesozoic and Tertiary gneiss and granite. Twig ash was analyzed for 35 elements by instrumental neutron activation.
Results indicate that certain elements - namely Fe, Co, U, and rare-earth elements - found in spruce trees could reflect the chemical contrast between the two bedrock types on either side of Weedon Fault, despite the presence of glacial overburden. For some transects, concentration contrasts are
quite sharp and appear to clearly delineate the fault, while others are much less noticeable and are subtle contrasts. For elements such as Ca and Zn, concentrations were controlled by the growth characteristics of spruce trees rather than the bedrock composition.
High Au concentrations in twigs were found scattered throughout the study area and have no obvious relationship with the fault. In several areas, anomalous Au concentrations were accompanied by enrichment of Ba and As. Whereas data analysis revealed no significant statistical correlation between Au
and any other element, spatial relationships were noted.
A review of NBCC 2005 seismic hazard results for Canada - the interface to the ground and prognosis for urban risk mitigation
Authors: Adam J , Halchuk S
Published: November 2016

We summarize the methods being used for the new seismic hazard maps of Canada and estimate median ground motion on firm soil sites for a probability of exceedence of 2% in 50 years. Spectral acceleration at 0.2, 0.5, 1.0 and 2.0 second periods and peak
acceleration will form the basis of the seismic provisions of the 2005 National Building Code of Canada. New soil factors will convert these firm soil values to other foundation conditions. The factors act to reduce design ground motions on rock and increase them on soft soils, and account for
non-linear behaviour of soils under strong shaking. We discuss implications for geotechnical design, microzonation, and urban risk.
Experiences of women who reported sexual assault at a provincial hospital, South Africa
Authors: Sebaeng Jeanette M. , Davhana- Maselesele Mashudu , Manyedi Eva
Published: November 2016

Background: Sexual assault poses a serious health problem to both the survivor and the health system. Experiencing sexual assault requires women to seek medical and psychological assistance as part of their journey towards recovery. This study examined the experiences of women who received post-sexual assault services from a specialised care centre within a provincial hospital.Methods: A qualitative, exploratory and contextual design was used to explore and describe experiences of women. Data were obtained through individual in-depth interviews from a total of 18 women aged between 18 and 55 years. Interviews were supplemented by the researcher’s field notes and audiotape recordings.Results: Findings yielded two main themes: Women expressed their lived experiences of sexual assault characterised by different forms of trauma. The second theme was an expression of a need for safety and support.Conclusion: Women who experience sexual assault are left with devastating effects such as physical and psychological harm and social victimisation. There is also a need for safety and support towards the recovery of these women. This study recommends that professional practitioners involved in the management of sexual assault be sensitised regarding the ordeal experienced by women and stop perceiving survivors as crime scene ‘clients’ from whom only medico-legal evidence has to be collected. Professional practitioners and family members must be supportive, non-judgemental and considerate of the dignity of survivors. The establishment of sexual assault response teams (SART) is also recommended. There should also be inter-professional education for better coordination of services rendered to sexually assaulted women.
Mishti Copes with diabetes: Yoga
Authors: Kanungo Alok , Chugh Shuchy
Published: November 2016

Type 1 diabetes is a lifelong disorder and its diagnosis usually comes as a shock not only for the child but for the whole family. It has a huge psychosocial impact as children with diabetes face discrimination and sometimes also limited social relationships. This stress and shock not only has ill effect on overall health but all disturbs daily routine and discipline which is essential for managing diabetes. Yoga is a traditional Indian practice which is not only a great way to relax and unwind, but also to get fit. It provides discipline, physical strength, flexibility and also emotional wellbeing and thus helps in coping with diabetes.
QUIC Transport and Dispersion Modeling of Vehicle Emissions in Cities for Better Public Health Assessments
Authors: Brown Michael J. , Williams Michael D. , Nelson Matthew A. , Werley Kenneth A.
Published: November 2016

The Quick Urban and Industrial Complex (QUIC) plume modeling system is used to explore how the transport and dispersion of vehicle emissions in cities are impacted by the presence of buildings. Using downtown Philadelphia as a test case, notional vehicle emissions of gases and particles are specified as line source releases on a subset of the east–west and north–south streets. Cases were run in flat terrain and with 3D buildings present in order to show the differences in the model-computed outdoor concentration fields with and without buildings present. The QUIC calculations show that buildings result in regions with much higher concentrations and other areas with much lower concentrations when compared to the flat-earth case. On the roads with vehicle emissions, street-level concentrations were up to a factor of 10 higher when buildings were on either side of the street as compared to the flat-earth case due to trapping of pollutants between buildings. However, on roads without vehicle emissions and in other open areas, the concentrations were up to a factor of 100 times smaller as compared to the flat earth case because of vertical mixing of the vehicle emissions to building height in the cavity circulation that develops on the downwind side of unsheltered buildings. QUIC was also used to calculate infiltration of the contaminant into the buildings. Indoor concentration levels were found to be much lower than outdoor concentrations because of deposition onto indoor surfaces and particulate capture for buildings with filtration systems. Large differences in indoor concentrations from building to building resulted from differences in leakiness, air handling unit volume exchange rates, and filter type and for naturally ventilated buildings, whether or not the building was sheltered from the prevailing wind by a building immediately upwind.
A Non-trivial Ghost Kernel for Complex Projective Spaces with Symmetries
Authors: Szymik Markus
Published: November 2016

It is shown that the ghost kernel for certain equivariant stable cohomotopy groups of projective spaces is non-trivial. The proof is based on the Borel cohomology Adams spectral sequence and the calculations with the Steenrod algebra afforded by it.

Authors: Yousofzadeh Malihe
Published: November 2016

We introduce the notion of extended affine Lie superalgebras and investigate the properties of their root systems. Extended affine Lie algebras, invariant affine reflection algebras, finite-dimensional basic classical simple Lie superalgebras and affine Lie superalgebras are examples of extended affine Lie superalgebras.
Factores influyentes en el éxito de la comunicación hospitalaria vía redes sociales
Authors: Rando Cueto Dolores , Paniagua Rojano Francisco Javier , De las Heras Pedrosa Carlos
Published: November 2016

El objeto de estudio del presente artículo es la comunicación online en corporaciones hospitalarias españolas, en concreto, de los centros más influyentes en Twitter. Hipótesis y objetivos. Partimos de la hipótesis de que existe una baja participación de los hospitales en los medios sociales, a pesar del interés de los usuarios. El objetivo principal es definir las características y la estrategia para proponer ideas para optimizar la relación entre hospitales y ciudadanos a través de las redes sociales. Metodología. La metodología empleada se basa, fundamentalmente, en el análisis  cuantitativo y cualitativo de la actividad en Twitter de aquellos centros sanitarios especializados con mayor interacción. Resultados. Se observa el interés de los pacientes por la información y la actividad que los centros sanitarios comparten en las redes sociales, cuyos mensajes se pueden clasificar en: de ámbito no sanitario o relacionados con cuestiones extrínsecas a la actividad asistencial también suscitan un destacado interés, seguidos por aquellos sobre promoción y prevención sanitaria y de reconocimiento a protagonistas de alguna intervención en el entorno hospitalario. En la misma línea, se puede afirmar que se usa, en general, un tono cercano. Conclusiones. A partir de este trabajo, se proponen algunas estrategias encaminadas a mejorar la comunicación entre el hospital y sus diferentes stakeholders y, por ende, situaciones que rodean a los usuarios de los sistemas sanitarios, centradas en la relación entre atención sanitaria y el bienestar de la ciudadanía.

Authors: Rúas-Araújo José , Campos-Freire Francisco , Puentes-Rivera Iván
Published: November 2016

Se analiza el conocimiento, uso, valoración e impacto de las redes sociales Facebook y Twitter y los buscadores bibliográficos por parte del Personal Docente e Investigador (PDI) de las tres universidades gallegas. Metodología: Se realizó una encuesta sobre el universo de los 5.498 docentes e investigadores, obteniendo una muestra de 463 respuestas, con un margen de error inferior al 5% y un intervalo de confianza del 95%. Resultados: El 50,2% del PDI considera la idoneidad de Facebook y Twitter para la docencia y la investigación frente al 49,8% que no. Scopus y Google Scholar son los buscadores más conocidos, con porcentajes superiores al 80% y una utilización superior al 60%, y EBSCO y EMBASE los menos. Discusión y conclusiones: Existe un estimable conocimiento y utilización de buscadores y opiniones enfrentadas entre quienes consideran la idoneidad de Facebook y Twitter para la docencia y la investigación y quienes no, lo cual sugiere un debate.
Вероятностное представление решения задачи Коши для эволюционного уравнения с оператором Римана-Лиувилля
Authors: Platonova Mariya V
Published: November 2016

В работе изучаются возможности вероятностной аппроксимации решения задачи Коши для эволюционных уравнений с оператором дробного дифференцирования порядка больше двух. С этой целью строятся аналоги односторонних $\alpha$-устойчивых распределений при нецелых $\alpha>2$. Хотя плотности таких распределений являются уже знакопеременными функциями, тем не менее, пользуясь методами теории обобщенных функций, удается придать им точный вероятностный смысл.
Неравенства концентрации для выборок без возвращений
Authors: Tolstikhin Ilya O
Published: November 2016

В работе рассматривается явление концентрации значений функций случайных величин, выбранных без возвращений из фиксированного конечного множества, вблизи их математических ожиданий - задача, актуальная в ряде приложений, включая трансдуктивную постановку теории статистического обучения. Помимо
обзора известных результатов, активно применяющихся в литературе, в работе изучается два общих подхода, ведущих во многих случаях к достаточно точным неравенствам концентрации. Первый основан на субгауссовском неравенстве С. Г. Бобкова [8] для функций, определенных на срезе булева куба. Второй подход, предложенный в известной работе В. Хефдинга [17], сводит задачу к рассмотрению выборки независимых случайных величин. На их основе получен ряд неравенств концентрации, включая два новых неравенства для супремумов эмпирических процессов для выборок без возвращений.
From moment explosion to the asymptotic behavior of the cumulative distribution for a random variable
Authors: Aly S M
Published: November 2016

В статье изучается связь тауберова типа между порождающей функцией моментов и дополнительной кумулятивной функцией распределения случайной величины, чья порождающая функция моментов конечна только на части действительной оси. Мы связываем поведение правого хвоста кумулятивной функции распределения такой случайной величины с поведением ее порождающей функции моментов вблизи критического значения. Эти результаты применяются к произвольной суперпозиции процесса Кокса-Ингерсолла-Росса и интеграла по времени от этого процесса.
Binomial-$\chi^2$ vector random fields
Authors: Ma Chunsheng
Published: November 2016

В статье вводится новый класс негауссовских векторных случайных полей с пространственными, временными или пространственно-временными индексами, называемый $\chi^2$-биномиальными векторными случайными полями и включающий в себя как частный случай векторные случайные $\chi^2$-поля. Мы определяем $\chi^2$-биномиальное векторное случайное поле как сумму биномиального числа квадратов независимых гуассовских векторных случайных полей с индексами из пространственной, временной или пространственно-временной области. Оно является векторным случайным полем второго порядка и обладает тем интересным свойством, что его конечномерные преобразования Лапласа определяются не его собственными матрицами ковариаций, а матрицами ковариаций исходного гауссовского поля. Мы изучаем основные свойства $\chi^2$-биномиальных векторных случайных полей и, используя двумерное нормальное распределение и его плотность, а также связанные с ними функции, описываем некоторые прямые/перекрестные ковариации для эллиптически контурированных (сферически инвариантных) и $\chi^2$-биномиальных векторных случайных полей.
