Symmetric Hadamard matrices of order 116
and 172 exist

Abstract
We construct new symmetric Hadamard matrices of orders 92, 116, and 172. While the existence
of those of order 92 was known since 1978, the orders 116 and 172 are new. Our construction is based on
a recent new combinatorial array (GP array) discovered by N. A. Balonin and J. Seberry. For order 116 we
used an adaptation of an algorithm for parallel collision search. The adaptation pertains to the modification
of some aspects of the algorithm to make it suitable to solve a 3-way matching problem. We also point out
that a new infinite series of symmetric Hadamard matrices arises by plugging into the GP array the matrices
constructed by Xia, Xia, Seberry, and Wu in 2005.

Published: October 2015

AbstractCells must quickly respond and efficiently adapt to environmental changes. The yeast Saccharomyces cerevisiae has multiple pathways that respond to specific environmental insults, as well as a generic stress response program. The later is regulated by two transcription factors, Msn2 and Msn4, that integrate information from upstream pathways to produce fast, tunable, and robust response to different environmental changes. To understand this integration, we employed a systematic approach to genetically dissect the contribution of various cellular pathways to Msn2/4 regulation under a range of stress and growth conditions. We established a high‐throughput liquid handling and automated flow cytometry system and measured GFP levels in 68 single‐knockout and 1,566 double‐knockout strains that carry an HSP12‐GFP allele as a reporter for Msn2/4 activity. Based on the expression of this Msn2/4 reporter in five different conditions, we identified numerous genetic and epistatic interactions between different components in the network upstream to Msn2/4. Our analysis gains new insights into the functional specialization of the RAS paralogs in the repression of stress response and identifies a three‐way crosstalk between the Mediator complex, the HOG MAPK pathway, and the cAMP/PKA pathway.
Hysteresis of targeting civilians in armed conflicts
Authors: Lee Uih Ran 
Published: October 2015

This article explores warring groups’ intentional targeting behavior against civilians, a strictly prohibited war strategy by international norms. Using dynamic panel regressions run on a comprehensive dataset of contemporary warfare, which covers 22 years (1989-2010), I find that warring actors involved in prolonged armed (15-22 years) conflict target civilians more often than those involved in shorter-duration warfare. Also, for warring groups engaged in prolonged armed conflict, lethal behavior against civilians tends to be intensified if targeting is repeated over time, although this hysteresis effect appears to persist only for one year. It is hypothesized that the mounting war cost of prolonged conflict inclines warring groups toward the presumably cheaper targeting of noncombatant civilians rather than battling combatant military or other armed personnel.

Composite Nanocrystalline/Amorphous Thin Films for Particle Detector Applications
Authors: Razieli Zvie , Rusack Roger , Kakalios James 
Published: October 2015

ABSTRACTThin films of amorphous silicon with nanocrystalline silicon inclusions are fabricated using a dual plasma PECVD co-deposition system. Raman spectroscopy and X-ray diffraction confirmed the crystallinity of the embedded nanocrystals as well as their diameter, which is varied from 4.3 nm to 17.5 nm. The dark conductivity of the films is highly dependent on the crystal fraction, with a maximum room temperature conductivity found for a crystal concentration of 5.5%, well below the percolation threshold. Proton irradiation at energies of 217 MeV with a total fluence of 5 x1012 protons/cm2 caused no significant radiation damage. The enhancement of the conductivity, along with the absence of radiation damage suggests this material may be a candidate for use in the next generation of particle detectors in the Compact Muon Solenoid in the Large Hadron Collider at CERN.

ABSTRACTThis paper describes the characteristics of damage, introduced under different conditions of diamond wire sawing, on the Si wafer surfaces. The damage occurs in the form of frozen-in dislocations, phase changes, and microcracks. The in-depth damage was determined by conventional ways such as TEM, SEM and angle-polishing/defect-etching, which only provide local information. We have also applied a new technique based on sequential measurement of the minority carrier lifetime after etching thin layers from the surfaces to determine average damage depth and its in-depth distribution. The lateral spatial damage variations, which seem to be mainly related to wire reciprocation process, were observed by photoluminescence and lifetime mapping. Our results show a strong correlation of damage depth on the diamond grit size and wire usage.

A ação do laser arseneto de gálio alumínio (GaAlAs) nos comprimentos de onda 685nm e 830nm em cultura de Trichophyton rubrum, foi estudada visando obter os metabólitos secundários e avaliar a citotoxicidade dos mesmos em cultura de células. Foram utilizadas cepas do dermatófito T. rubrum provenientes do laboratório de Microbiologia da Universidade do Vale do Paraíba. O cultivo foi realizado em meio de cultura sólido de ágar Sabouraud (Merck, Alemanha) em placa de Petri. A colônia de T. rubrum foi irradiada com o laser (GaAlAs) a uma distância de 1cm da placa e incubadas em estufa 26ºC. Para o ensaio de citotoxicidade foi utilizada a linhagem ce-lular L929 (tecido conjuntivo de camundongo) proveniente do laboratório Adolf Lutz em São Paulo. As células foram plaqueadas e incubadas com o extrato fúngico em diferentes concentrações, por 1 h. Após esta incubação foi reali-zado o teste de Metil tiazol tetrazólio (MTT) para avaliação da citotoxicidade. Obteve-se uma diferença no cresci-mento das colônias controle e irradiadas a 685 nm estatisticamente significante (p<0,05). Na análise estatística com-parativa da citotoxicidade causada pelos extratos nas concentrações 2,5 mg/ml e 25x10-6 mg/ml, foi obtido p<0,05, o mesmo ocorreu entre as concentrações 25x10-2 mg/ml e 25x10-6 mg/ml. Na concentração de 25x10-2 mg/ml, observa-se uma elevação considerável (78,55%) na atividade mitocondrial dos grupos com tratamento em relação ao controle. O laser GaAlAs, nas condições metodológicas deste estudo, apresentou efeitos no metabolismo celular, alteração de morfologia e da taxa de crescimento da colônia in vitro. O extrato fúngico das colônias irradiadas apre-sentou efeito bioestimulador quando comparado ao extrato obtido do grupo controle e sem tratamento com laser.

Objectives. We examined factors associated with frequent hospitalizations and emergency department (ED) visits among Medicaid members who were homeless. Methods. We included 6494 Massachusetts Medicaid members who received services from a health care for the homeless program in 2010. We used negative binomial regression to examine variables associated with frequent utilization. Results. Approximately one third of the study population had at least 1 hospitalization and two thirds had 1 or more ED visits. More than 70% of hospitalizations and ED visits were incurred by only 12% and 21% of these members, respectively. Homeless individuals with co-occurring mental illness and substance use disorders were at greatest risk for frequent hospitalizations and ED visits (e.g., incidence rate ratios [IRRs] = 2.9–13.8 for hospitalizations). Individuals living on the streets also had significantly higher utilization (IRR = 1.5). Conclusions. Despite having insurance coverage, homeless Medicaid members experienced frequent hospitalizations and ED visits. States could consider provisions under the Patient Protection and Affordable Care Act (e.g., Medicaid expansion and Health Homes) jointly with housing programs to meet the needs of homeless individuals, which may improve the quality and cost effectiveness of care.

Published: October 2015

Objectives. We sought to describe changes in young adults’ routine care and usual sources of care (USCs), according to provider specialty, after implementation of extended dependent coverage under the Affordable Care Act (ACA) in 2010. Methods. We used Medical Expenditure Panel Survey data from 2006 to 2012 to examine young adults’ receipt of routine care in the preceding year, identification of a USC, and USC provider specialties (pediatrics, family medicine, internal medicine, and obstetrics and gynecology). Results. The percentage of young adults who sought routine care increased from 42.4% in 2006 to 49.5% in 2012 (P < .001). The percentage identifying a USC remained stable at approximately 60%. Among young adults with a USC, there was a trend between 2006 and 2012 toward increasing percentages with pediatric (7.6% vs 9.1%) and family medicine (75.9% vs 80.9%) providers and declining percentages with internal medicine (11.5% vs 7.6%) and obstetrics and gynecology (5.0% vs 2.5%) providers. Conclusions. Efforts under the ACA to increase health insurance coverage had favorable effects on young adults’ use of routine care. Monitoring routine care use and USC choices in this group can inform primary care workforce needs and graduate medical education priorities across specialties.

Published: October 2015

Objectives. We investigated how access to and continuity of care might be affected by transitions between health insurance coverage sources, including the Marketplace (also called the Exchange), Medicaid, and the Children’s Health Insurance Program (CHIP). Methods. From January to February 2014 and from August to September 2014, we searched provider directories for networks of primary care physicians and selected pediatric specialists participating in Marketplace, Medicaid, and CHIP in 6 market areas of the United States and calculated the degree to which networks overlapped. Results. Networks of physicians in Medicaid and CHIP were nearly identical, meaning transitions between those programs may not result in much physician disruption. This was not the case for Marketplace and Medicaid and CHIP networks. Conclusions. Transitions from the Marketplace to Medicaid or CHIP may result in different degrees of physician disruption for consumers depending on where they live and what type of Marketplace product they purchase.

Abstract
Over the last several years, the ability to perform accurate quantitative formation evaluation in high angle and horizontal wells has been recognized as high priority for major operators. The Logging While Drilling (LWD) has witnessed a revolution in technology in recent years. These new LWD tools have gained recognition in geosteering and well placement operations.
The need for advanced formation evaluation is more critical for carbonate reservoir where the complex pore structure will play a big role in fluid mobility. Formation mobility in carbonate reservoirs has been always an important output of any formation evaluation.
The South Fuwaris Field is located in the Partitioned Zone between Kuwait and Saudi Arabia. The Lower Cretaceous Ratawi reservoirs were discovered in 1961, and production commenced in 1963. There are two major reservoirs – the Ratawi Limestone, which is predominantly developed by vertical wells, and the Ratawi Oolite, which is exclusively developed by horizontal wells. The reservoirs comprise low-moderate permeability limestone. Interpretation is complicated by the existence of microporosity, mesoporosity and macroporosity. Understanding of pore type distribution would be of value is the placement of future Ratawi Oolite horizontal wells.
The LWD resistivity was used in this field as standard resistivity tool (Laterolog type) to determine the true formation resistivity. In addition, due to the fact that LWD tools measure while rotating, several resistivity images with different depth of investigation are also available in real time and recorded mode.
In this case, the LWD resistivity imaging was used to study azimuthal formation porosity distribution in order to quantify the different porosity portions (Primary / Secondary). Following that, an empirical equation was used to determine formation permeability profile. This profile can be further improved when calibrated with core data or formation pressure survey while drilling.

Abstract
The properties of the filter cake through maximum reservoir contact (MRC) and extended reach (ER) wells are not constant due to the presence of the drilled-cutting. The formation cuttings contamination in the drilling fluid during the drilling operation influences the drilling fluid properties as well as the filter cake properties.
This study focuses on assessing the effect of the sandstone formation drilled-cuttings on the filter cake sealing properties and the internal solid invasion depth in horizontal section. Three different drilling fluid samples were collected at different points of a horizontal section during drilling operation. The drilling fluid samples were collected at the flow line coming from the well after shale shaker. High pressure high temperature (HPHT) fluid loss test was conducted to form the filter cake on top of 0.25 inch ceramic disc (35 micron). The composition of filter cake was evaluated using SEM and XRD. CT scan technique was used to evaluate the internal solids invasion of the different drilling fluid samples.
The results from this study showed that the internal invasion is directly affected by the changes of sand contents in the filter cake. The internal drilling fluid solids invasion depth reached 3-4 mm when the sand content was lower than 25 wt % of the filter cake solids. Increasing the sand content more than 30 wt % in the filter cake solids allowed the drilling fluid to invade up to more than 6 mm with high concentration due to the degradation in the cake permeability.
The result of this work will be useful to investigate diversion process to remove the formation damage from maximum reservoir contact and extended reach wells in sandstone reservoirs.
