Design of Droop-based Control for Power Management in Islanded RL-type Microgrids
Authors: Imran Azim Mohammad , Hossain Jahangir , Pota Hemanshu 
Published: March 2017

Abstract
This paper proposes a new type of generalized droop-based proportional power sharing scheme during load change for parallel inverter-interfaced islanded microgrids, which is an automatic strategy and is independent of any particular nature of transmission lines, i.e., resistive or inductive. Real and reactive powers are shared in proportion to the droop gains by implementing the voltage control law proposed in this paper; in which the inverter-interfaced voltage-sources are kept at equal reference values. The control gains are chosen based on eigenvalue analysis in a way that the system stability is ascertained. The performance of the designed controller is simulated under different microgrid structures such as load variation and various types of transmission lines; in which the results show superior dynamic performance in comparison to the conventional droop-based control strategy.
Effects of peripherally and centrally applied ghrelin on the oxidative stress induced by renin angiotensin system in a rat model of renovascular hypertension
Authors: Boshra Vivian , Abbas Amr M. 
Published: March 2017

Abstract

Background:
Renovascular hypertension (RVH) is a result of renal artery stenosis, which is commonly due to astherosclerosis. In this study, we aimed to clarify the central and peripheral effects of ghrelin on the renin-angiotensin system (RAS) in a rat model of RVH.

Methods:
RVH was induced in rats by partial subdiaphragmatic aortic constriction. Experiment A was designed to assess the central effect of ghrelin via the intracerebroventricular (ICV) injection of ghrelin (5 μg/kg) or losartan (0.01 mg/kg) in RVH rats. Experiment B was designed to assess the peripheral effect of ghrelin via the subcutaneous (SC) injection of ghrelin (150 μg/kg) or losartan (10 mg/kg) for 7 consecutive days. Mean arterial blood pressure (MAP), heart rate, plasma renin activity (PRA), and oxidative stress markers were measured in all rats. In addition, angiotensin II receptor type 1 (AT1R) concentration was measured in the hypothalamus of rats in Experiment B.

Results:
RVH significantly increased brain AT1R, PRA, as well as the brain and plasma oxidative stress. Either SC or ICV ghrelin or losartan caused a significant decrease in MAP with no change in the heart rate. Central ghrelin or losartan caused a significant decrease in brain AT1R with significant alleviation of the brain oxidative stress. Central ghrelin caused a significant decrease in PRA, whereas central losartan caused a significant increase in PRA. SC ghrelin significantly decreased PRA and plasma oxidative stress, whereas SC losartan significantly increased PRA and decreased plasma oxidative stress.

Conclusions:
The hypotensive effect of ghrelin is mediated through the amelioration of oxidative stress, which is induced by RAS centrally and peripherally.

AbstractBackground:Excess weight, unhealthy lifestyle habits and their sequelae have become a well-recognized public health problem in most countries. The objective of the study was to examine the relationship of adolescent overweight/obesity with behavioral habits and their association with blood pressure (BP) and lipid profile.Methods:Anthropometric parameters, lifestyle, BP and lipid profile of 736 adolescents were evaluated cross-sectionally. The classifications of normal weight, overweight and obese were based on BMI z-scores.Results:About 42.1% of adolescents were overweight/obese, 11.3% were smokers, 33.2% consumed alcohol and 34% reported low activity. Males began smoking earlier, consumed alcohol more often, exercised less and spent more screen time than females. Alcohol consumption was more prevalent among smokers and was associated with higher BP and dyslipidemia. Smokers exercised less intensely and had lower high density lipoprotein-cholesterol (HDL-C) than non-smokers. Obesity was a risk factor for higher BP and dyslipidemia. Longer screen time was associated with higher triglycerides, while intense physical activity with lower systolic BP.Conclusions:Obesity is related to an adverse lipid and BP profile during adolescence. Clustering of hazardous habits was observed, which is known to aggravate the cardiovascular risk.

AbstractThis research evaluates habitat and forage use by a reintroduced population of endangered banteng (Bos javanicusd’Alton, 1823) in Khao Khieo-Khao Chomphu Wildlife Sanctuary, Thailand based on fieldwork conducted between November 2007 and September 2009. Thirteen banteng bred in Khao Kheow Open Zoo were accidentally introduced into the Khao Khieo-Khao Chomphu Wildlife Sanctuary in 1988. Forage species were identified by fecal analysis. The results from field study of showed that the population structure ratio among adults, juveniles and calves was 1:0.5:0.3, respectively. A multiple logistic regression habitat suitability model classified banteng as associated with mixed deciduous forest and agricultural areas (cassava and coconut), at low elevation, distant from human settlements. The kernel density estimate of area use for agriculture was 0.32 km2, and for mixed deciduous forest the estimate was 10.75 km2and 6.2 km2in the dry and wet seasons, respectively. When the wet and dry seasons are combined, the total area use for agriculture was 0.35 km2and for mixed deciduous forest, it was 11.40 km2. Twenty-three forage species were identified using a combination of fecal analysis and direct observation. Fecal specimens contained high levels of moisture and protein. Major risks to the feral banteng population are low genetic diversity, habitat destruction and poaching. These findings are important for possible translocations elsewhere.
Counting the Particles: Entity and Identity in the Philosophy of Physics
Authors: Berto Francesco 
Published: March 2017

AbstractI would like to attack a certain view: the view that the concept of identity can fail to apply to some things although, for some positive integern, we havenof them. The idea of entities without self-identity is seriously entertained in the philosophy of quantum mechanics (QM). It is so pervasive that it has been labelled the Received View (French and Krause 2006.Identity in Physics: A Historical, Philosophical, and Formal Analysis. Oxford: Oxford UP: 105). I introduce the Received View in Section 1. In Section 2 I explain what I mean by “entity” (synonymously, by “object” and “thing”), and I argue that supporters of the Received View should agree with my characterization of the corresponding notion ofentity(object, thing). I also explain what I mean by “identity”, and I show that supporters of the Received View agree with my characterization of that notion. In Section 3 I argue that the concept of identity, so characterized, is one with the concept of oneness. Thus, it cannot but apply to what belongs to a collection withnelements,nbeing a positive integer. In Section 4 I add some considerations on the primitiveness of identity or unity and the status of the Identity of Indiscernibles. In Section 5 I address the problem of how reference to indiscernible objects with identity can be achieved.
Managing complaints in multilingual care encounters

Published: March 2017

AbstractTroubles-telling and complaints are common in contexts of care for older people and need to be managed by care staff in a respectful manner. This paper examines the handling of an older person’s complaints in multilingual care encounters that involve participants who do not share a common language. The data consist of video-recordings and ethnographic fieldwork in a residential home for older people in Sweden that is characterised by a variety of languages and backgrounds. The findings are based on analyses of multi-party interactions involving an Arabic-speaking resident and caregivers with different levels of knowledge in different languages. We focus on complaint sequences when the resident expresses a negative stance (displeasure, anger, etc.) towards some difficult circumstance. Using the methodology of conversation analysis, we analyse the affect-regulating work through which the caregivers attempt to turn a pressing situation into a moment of cheerfulness and intimacy. The analyses bring to light the multilingual practices that the caregivers draw upon in pursuing this work, such as translating and giving voice to the resident’s complaining.

Mechanical properties of natural fibre polymer composites
Authors: Sinha Agnivesh Kumar , Narang Harendra K. , Bhattacharya Somnath 
Published: March 2017

Abstract
Extensive efforts have been made in the last decade for the development of natural fibre composites. This development paved the way for engineers and researchers to come up with natural fibre composites (NFCs) that exhibit better mechanical properties. The present review is based on the mechanical properties of jute, abaca, coconut, kenaf, sisal, and bamboo fibre-reinforced composites. Before selecting any NFC for a particular application, it becomes necessary to understand its compatibility for the same, which can be decided by knowing its mechanical properties such as tensile, flexural, and impact strengths. This review paper emphasises on the factors influencing the mechanical properties of NFCs like the type of matrix and fibre, interfacial adhesion, and compatibility between matrix and fibre. Efforts are also made to unveil the research gaps from the past literatures, as a result of which it is inferred that there is very limited work published in the field of vibration incorporating potential fillers such as red mud and fly ash with NFCs.

Abstract
In this work, an amino-functionalized graphene oxide (AFGO) was synthesized by graphene oxide (GO) and ethylene diamine. A novel amino-functionalized graphene oxide/azobenzene polyimide (AFGO/ACPI) was synthesized with AFGO, azobenzene chromophore and pyromellitic dianhydride (PMDA). The structure, mechanical and thermal property of AFGO/ACPI were characterized and measured by fourier transform infrared, UV-visible spectroscopy, near-infrared spectrum, thermogravimetric analysis and differential scanning calorimetry. To obtain the refractive index of AFGO/ACPI at different temperature and wavelength (532 nm, 650 nm and 850 nm), the attenuated total reflection (ATR) method was used to measure, and thermo optic coefficients (dn/dT) were −7.22×10−4 (532 nm), −6.20×10−4 (650 nm) and −5.84×10−4 (850 nm) °C−1, respectively. The transmission loss of AFGO/ACPI thin film was surveyed using the CCD digital imaging devices and the value was 0.167 dB/cm. According to the thermo-optic effect of AFGO/ACPI film, the 1×2 Y-branch and 2×2 Mach-Zehnder optical switches were simulated. The results showed that the power consumptions of the 1×2 Y-branch and 2×2 Mach-Zehnder optical switches were only 0.63 mW and 1.45 mW. The response time was about 0.5 ms, and compared to the normal polymeric thermo-optic switch, it can improve the response time and contribute to researches of optical switches.

Postinjury epilepsy (PIE) is a devastating sequela of various brain insults. While recent studies offer novel insights into the mechanisms underlying epileptogenesis and discover potential preventive treatments, the lack of PIE biomarkers hinders the clinical implementation of such treatments. Here we explored the biomarker potential of different electrographic features in five models of PIE. Electrocorticographic or intrahippocampal recordings of epileptogenesis (from the insult to the first spontaneous seizure) from two laboratories were analyzed in three mouse and two rat PIE models. Time, frequency, and fractal and nonlinear properties of the signals were examined, in addition to the daily rate of epileptiform spikes, the relative power of five frequency bands (theta, alpha, beta, low gamma, and high gamma) and the dynamics of these features over time. During the latent pre-seizure period, epileptiform spikes were more frequent in epileptic compared with nonepileptic rodents; however, this feature showed limited predictive power due to high inter- and intra-animal variability. While nondynamic rhythmic representation failed to predict epilepsy, the dynamics of the theta band were found to predict PIE with a sensitivity and specificity of >90%. Moreover, theta dynamics were found to be inversely correlated with the latency period (and thus predict the onset of seizures) and with the power change of the high-gamma rhythm. In addition, changes in theta band power during epileptogenesis were associated with altered locomotor activity and distorted circadian rhythm. These results suggest that changes in theta band during the epileptogenic period may serve as a diagnostic biomarker for epileptogenesis, able to predict the future onset of spontaneous seizures.SIGNIFICANCE STATEMENTPostinjury epilepsy is an unpreventable and devastating disorder that develops following brain injuries, such as traumatic brain injury and stroke, and is often associated with neuropsychiatric comorbidities. As PIE affects as many as 20% of brain-injured patients, reliable biomarkers are imperative before any preclinical therapeutics can find clinical translation. We demonstrate the capacity to predict the epileptic outcome in five different models of PIE, highlighting theta rhythm dynamics as a promising biomarker for epilepsy. Our findings prompt the exploration of theta dynamics (using repeated electroencephalographic recordings) as an epilepsy biomarker in brain injury patients.

AbstractMeiotic crossover frequencies show wide variation among organisms. But most organisms maintain at least one crossover per homolog pair (obligate crossover). In Saccharomyces cerevisiae, previous studies have shown crossover frequencies are reduced in the mismatch repair related mutant mlh3Δ and enhanced in a meiotic checkpoint mutant pch2Δ by up to twofold at specific chromosomal loci, but both mutants maintain high spore viability. We analyzed meiotic recombination events genome-wide in mlh3Δ, pch2Δ, and mlh3Δ pch2Δ mutants to test the effect of variation in crossover frequency on obligate crossovers. mlh3Δ showed ∼30% genome-wide reduction in crossovers (64 crossovers per meiosis) and loss of the obligate crossover, but nonexchange chromosomes were efficiently segregated. pch2Δ showed ∼50% genome-wide increase in crossover frequency (137 crossovers per meiosis), elevated noncrossovers as well as loss of chromosome size dependent double-strand break formation. Meiotic defects associated with pch2∆ did not cause significant increase in nonexchange chromosome frequency. Crossovers were restored to wild-type frequency in the double mutant mlh3Δ pch2Δ (100 crossovers per meiosis), but obligate crossovers were compromised. Genetic interference was reduced in mlh3Δ, pch2Δ, and mlh3Δ pch2Δ. Triple mutant analysis of mlh3Δ pch2Δ with other resolvase mutants showed that most of the crossovers in mlh3Δ pch2Δ are made through the Mus81-Mms4 pathway. These results are consistent with a requirement for increased crossover frequencies in the absence of genetic interference for obligate crossovers. In conclusion, these data suggest crossover frequencies and the strength of genetic interference in an organism are mutually optimized to ensure obligate crossovers.
A Phylogenetic Codon Substitution Model for Antibody Lineages
Authors: Hoehn Kenneth B , Lunter Gerton , Pybus Oliver G 
Published: March 2017

AbstractPhylogenetic methods have shown promise in understanding the development of broadly neutralizing antibody lineages (bNAbs). However, the mutational process that generates these lineages, somatic hypermutation, is biased by hotspot motifs which violates important assumptions in most phylogenetic substitution models. Here, we develop a modified GY94-type substitution model that partially accounts for this context dependency while preserving independence of sites during calculation. This model shows a substantially better fit to three well-characterized bNAb lineages than the standard GY94 model. We also demonstrate how our model can be used to test hypotheses concerning the roles of different hotspot and coldspot motifs in the evolution of B-cell lineages. Further, we explore the consequences of the idea that the number of hotspot motifs, and perhaps the mutation rate in general, is expected to decay over time in individual bNAb lineages.
Germline Proliferation Is Regulated by Somatic Endocytic Genes via JNK and BMP Signaling in Drosophila

Published: March 2017

Abstract
Signals derived from the microenvironment contribute greatly to tumorigenesis . The underlying mechanism requires thorough investigation. Here, we use Drosophila testis as a model system to address this question, taking the advantage of the ease to distinguish germline and somatic cells and to track the cell numbers. In an EMS mutagenesis screen, we identified Rab5, a key factor in endocytosis, for its nonautonomous role in germline proliferation. The disruption of Rab5 in somatic cyst cells, which escort the development of germline lineage, induced the overproliferation of underdifferentiated but genetically wild-type germ cells. We demonstrated that this nonautonomous effect was mediated by the transcriptional activation of Dpp [the fly homolog of bone morphogenetic protein (BMP)] by examining the Dpp-reporter expression and knocking down Dpp to block germline overgrowth. Consistently, the protein levels of Bam, the germline prodifferentiation factor normally accumulated in the absence of BMP/Dpp signaling, decreased in the overproliferating germ cells. Further, we discovered that the JNK signaling pathway operated between Rab5 and Dpp, because simultaneously inhibiting the JNK pathway and Rab5 in cyst cells prevented both dpp transcription and germline tumor growth. Additionally, we found that multiple endocytic genes, such as avl, TSG101, Vps25, or Cdc42, were required in the somatic cyst cells to restrict germline amplification. These findings indicate that when the endocytic state of the surrounding cells is impaired, genetically wild-type germ cells overgrow. This nonautonomous model of tumorigenesis provides a simple system to dissect the relation between tumor and its niche.
A Search for Genes Mediating the Growth-Promoting Function of TGFβ in the Drosophila melanogaster Wing Disc

Published: March 2017

Abstract
Transforming Growth Factor β (TGFβ) signaling has a complex influence on cell proliferation, acting to stop cell division in differentiating cells, but also promoting cell division in immature cells. The activity of the pathway in Drosophila is mostly required to stimulate the proliferation of neural and epithelial tissues. Most interestingly, this function is not absolutely required for cell division, but it is needed for these tissues to reach their correct size. It is not known how TGFβ signaling promotes cell division in imaginal discs, or what the interactions between TGFβ activity and other signaling pathways regulating cell proliferation are. In this work, we have explored the disc autonomous function of TGFβ that promotes wing imaginal disc growth. We have studied the genetic interactions between TGFβ signaling and other pathways regulating wing disc growth, such as the Insulin and Hippo/Salvador/Warts pathways, as well as cell cycle regulators. We have also identified a collection of TGFβ candidate target genes affecting imaginal growth using expression profiles. These candidates correspond to genes participating in the regulation of a variety of biochemical processes, including different aspects of cell metabolism, suggesting that TGFβ could affect cell proliferation by regulating the metabolic fitness of imaginal cells.
Prophage Provide a Safe Haven for Adaptive Exploration in Temperate Viruses
Authors: Wahl Lindi M , Pattenden Tyler 
Published: March 2017

Abstract
Prophage sequences constitute a substantial fraction of the temperate virus gene pool. Although subject to mutational decay, prophage sequences can also be an important source of adaptive mutations for these viral populations. Here we develop a life-history model for temperate viruses, including both the virulent (lytic) and the temperate phases of the life cycle. We then examine the survival of mutations that increase fitness during the lytic phase (attachment rate, burst size), increase fitness in the temperate phase (increasing host survival), or affect transitions between the two phases (integration or induction probability). We find that beneficial mutations are much more likely to survive, ultimately, if they first occur in the prophage state. This conclusion applies even to traits that are only expressed during the lytic phase, and arises due to the substantially lower variance in the offspring distribution during the temperate cycle. This observation, however, is balanced by the fact that many more mutations can be generated during lytic replication. Overall we predict that the prophage state provides a refuge, relatively shielded from genetic drift, in which temperate viruses can explore possible adaptive steps.
