Abstract
We study the motion of charged dust grains at arbitrary distants from a rotating magnetic planet,we show that the model treated for dipole field is an excellent approximation in most cases for a generalized Stormer problem, But that fundamentally new physics arises with the inclusion of a quadrupolar magnetic term. In particular,the appearence of a new trajectories for different kind of charged dust grains,which are meaningful when the individual and a comparable impact of the co-rotational and gravitational fields is considered.Furthermore,a detailed mathematical treatment of equilibrium state for various phase spaces for charged components in prograde or retrograde rotation direction with analytical solutions for a non linear parametric system.
Lyra black holes and Hawking radiation
Authors: Bouhallouf Habiba 
Published: August 2019

Abstract
Sen and Dunn constructed a field equation which is analogous to Einstein’s field equations based on the Lyra’s geometry and gave series type solution to the static vacuum field equations which correspond to black holes. In this work, the Hawking radiation near the trapping horizon of Lyra black holes is derived and the obtained results are discussed.
Transport in exclusion processes with one-step memory: density dependence and optimal acceleration
Authors: Teomy Eial , Metzler Ralf 
Published: August 2019

Abstract
We study a lattice gas of persistent walkers, in which each site is occupied by at most one particle and the direction each particle attempts to move to depends on its last step. We analyse the mean squared displacement (MSD) of the particles as a function of the particle density and their persistence (the tendency to continue moving in the same direction). For positive persistence the MSD behaves as expected: it increases with the persistence and decreases with the density. However, for strong anti-persistence we find two different regimes, in which the dependence of the MSD on the density is non-monotonic. For very strong anti-persistence there is an optimal density at which the MSD reaches a maximum. In an intermediate regime, the MSD as a function of the density exhibits both a minimum and a maximum, a phenomenon which has not been observed before. We derive a mean-field theory which qualitatively explains this behaviour.
Public and Private Partnership for Sustainable Resource Use Initiative (Strategically Comprehensive Management To Back Up Formal Status of The ‘Cagar Biosfir Berbak-Sembilang’ as Another Targeting Site for The World Biosphere)
Authors: Sjarkowi Fachrurrozie 
Published: August 2019

Abstract
As clearly indicated in Lima Action Plan as adopted by MAB-ICC on March 19th 2016; UNESCO’s MAB will harness lessons learned by communicating and sharing information so that the WNBR (World Network of Biosphere Reserves) could develop appropriate but effectively functioning model of sustainable development for each site of World Biosphere. Appropriate management model for an ecosystem including its potential natural resources should get improved over time, “mainly in terms of governance, collaboration, and net working within the MAB and WNBR, by developing effective external partnership to ensure long term viability” (MAB-ICC, 2016). Clearly, a totally comprehensive ecosystem and multi-resource management must be prepared in order to fulfil the UNESCO’s expectation. Ecosystem management is more on-site oriented action, while multi-resource management is needed to control all socio-economic interests of the nearby people for the sake of their livelihoods. Of course the indigenous interests to those resource potentials must be fulfil selectively and directly connected with innovative roles of all other business actors as off-site economic beneficiaries. Hence, all activities (on-site and off-site CBBS-WB) have to come along with environmentally sound development strategies. There are 30 points of integrated management being offered herewith for effective execution.

Published: August 2019

AbstractThe origins of plasmacytoid dendritic cells (pDCs) have long been controversial and progenitors exclusively committed to this lineage have not been described. We show here that the fate of hematopoietic progenitors is determined in part by their surface levels of 9-O-acetyl sialic acid. Pro-pDCs were identified as lineage negative 9-O-acetyl sialic acid low progenitors that lack myeloid and lymphoid potential but differentiate into pre-pDCs. The latter cells are also lineage negative, 9-O-acetyl sialic acid low cells but are exclusively committed to the pDC lineage. Levels of 9-O-acetyl sialic acid provide a distinct way to define progenitors and thus facilitate the study of hematopoietic differentiation.

Abstract

Background
Since the identification of Zika virus (ZIKV) in Brazil in May 2015, the virus has spread throughout the Americas. However, ZIKV burden in the general population in affected countries remains unknown.

Methods
We conducted a general population survey in the different communities of French Guiana through individual interviews and serologic survey during June–October 2017. All serum samples were tested for anti-ZIKV immunoglobulin G antibodies using a recombinant antigen-based SGERPAxMap microsphere immunoassay, and some of them were further evaluated through anti-ZIKV microneutralization tests.

Results
The overall seroprevalence was estimated at 23.3% (95% confidence interval [CI], 20.9%–25.9%) among 2697 participants, varying from 0% to 45.6% according to municipalities. ZIKV circulated in a large majority of French Guiana but not in the most isolated forest areas. The proportion of reported symptomatic Zika infection was estimated at 25.5% (95% CI, 20.3%–31.4%) in individuals who tested positive for ZIKV.

Conclusions
This study described a large-scale representative ZIKV seroprevalence study in South America from the recent 2015–2016 Zika epidemic. Our findings reveal that the majority of the population remains susceptible to ZIKV, which could potentially allow future reintroductions of the virus.

Abstract

Objective
The purpose of this study was to evaluate the efficacy, late complications, and cosmetic outcomes of targeted intraoperative radiotherapy for the treatment of Chinese patients with early-stage breast cancer.

Methods
Between September 2014 and May 2017, breast cancer patients undergoing targeted intraoperative radiotherapy at our facility were retrospectively recruited for this study. Intraoperative radiotherapy was performed with a 50-kV X-ray source in an Intrabeam system (Carl Zeiss Meditec, Oberkochen, Germany). The one-time prescribed irradiation dose to the tumour bed was 20 Gy. Recurrence, death, late complications, and cosmetic outcomes were recorded. Late radiotoxicity was assessed based on the grading criteria of the Radiation Therapy Oncology Group.

Results
A total of 77 patients who were treated with targeted intraoperative radiotherapy only were recruited. The cohort had a mean age of 58 years; patients with T1, N0, and invasive ductal carcinoma accounted for 75.3, 89.6, and 84.4%, respectively; the median follow-up duration was 40 months; there were 2 patients of recurrence and 2 patients of death. There were no patients of cardiac toxicity or skin or lung radiotoxicity of grade 2 or above. The main complications were breast oedema (18.2%), seroma (15.6%), chromatosis (9.1%), induration (7.8%), pain (5.2%), skin depression (2.6%), mild dry cough (2.6%), delayed wound healing (1.3%), and wound infection (1.3%). Seventy-three patients participated in the cosmetic outcome evaluation, which yielded an excellent or good rate of 95.9%.

Conclusions
Due to its low recurrence rates, lack of high-grade late radiotoxicity, and excellent cosmetic outcomes, targeted intraoperative radiotherapy may be a suitable treatment for select early-stage breast cancer patients in China.
Refugees and Votes: The Impact of Refugee Influx and Internet on Voting Decisions
Authors: Karacuka Mehmet 
Published: August 2019

Abstract
The effects of refugee influx in recent years have been mostly analysed in terms of social and economic dimensions. However, the effects are especially important on the party system of the host countries that shape the political governance. In this study, we analyse the effects of massive refugee inflow from Syria to Turkey using regional data for the party votes in the 2015 parliamentary elections. The results show that the refugee crisis significantly increased the votes of the Nationalist Action Party (MHP) in the June election in the regions with higher refugee ratios. Due to the fact that public perceptions towards the refugees are shaped via media, and mostly new digital media, I also test whether Internet usage has an effect on the votes. I find a similar positive effect for the MHP when Internet and refugee variables are interacted. Furthermore, we find that the governing Justice and Development Party (AKP) did not lose many votes as voters appraised economic growth in the regions.
Setting research priorities for tackling climate change
Authors: Middendorf B Jan , Prasad P V Vara , Pierzynski Gary M 
Published: August 2019

Abstract
Addressing the complex issues related to climate change requires multiple innovative approaches to identify research priorities involving multidisciplinary research teams. Participatory approaches with a variety of perspectives were used to gain insights into critical issues such as defining and understanding sustainable intensification, climate smart agriculture, and soil fertility prioritization in sub-Saharan Africa. This analysis drew on the foundation principles of participatory research and fundamental facilitation skills, while grounded in scientific knowledge and understanding of these complex issues. This approach essentially incorporates the relevant principles of participatory learning and action, primarily designed for development projects, with a new set of players within the research and policy domain. The results of three case studies that utilized participatory techniques with a set of multidisciplinary research teams are presented. The case studies were: (i) Feed the Future Sustainable Intensification Innovation Lab (SIIL) proposal development grounded in country-led and national priorities in Bangladesh, Tanzania, and Cambodia; (ii) climate smart agriculture and sustainable intensification assessment and priority setting in Rwanda; and (iii) soil fertility prioritization in sub-Saharan Africa. We discuss how the future directions of such initiatives were shaped for improved outcomes.
Spiral instabilities: mechanism for recurrence
Authors: Sellwood J A , Carlberg Ray G 
Published: August 2019

ABSTRACT
We argue that self-excited instabilities are the cause of spiral patterns in simulations of unperturbed stellar discs. In previous papers, we have found that spiral patterns were caused by a few concurrent waves, which we claimed were modes. The superposition of a few steadily rotating waves inevitably causes the appearance of the disc to change continuously, and creates the kind of shearing spiral patterns that have been widely reported. Although we have found that individual modes last for relatively few rotations, spiral activity persists because fresh instabilities appear, which we suspected were excited by the changes to the disc caused by previous disturbances. Here we confirm our suspicion by demonstrating that scattering at either of the Lindblad resonances seeds a new groove-type instability. With this logical gap closed, our understanding of the behaviour in the simulations is almost complete. We believe that our robust mechanism is a major cause of spiral patterns in the old stellar discs of galaxies, including the Milky Way where we have previously reported evidence for resonance scattering in the recently released Gaia data.
Silica dust and sarcoidosis in Swedish construction workers
Authors: Jonsson E , Järvholm B , Andersson M 
Published: August 2019

Abstract

Background
The aetiology of sarcoidosis is not well established. In previous studies, smoking has been negatively associated with sarcoidosis and there are some indications of an association between exposure to silica dust and sarcoidosis.

Aims
To study the risk of sarcoidosis in relation to silica dust exposure.

Methods
A longitudinal cohort of construction workers linked with a registry of Swedish inpatient diagnoses. Workers were designated as exposed or unexposed to silica based on job titles in a job–exposure matrix. The relative risk (RR) was analysed with Poisson regression adjusting for age and smoking.

Results
We identified 371 cases of sarcoidosis among 297 917 male workers. There was an increased risk of sarcoidosis in the medium- to high-exposure group [RR 1.83 (95% confidence interval {CI} 1.14–2.95)]. A stratified analysis according to smoking showed that ever-smoking workers had an increased risk of sarcoidosis if highly exposed to silica dust [RR 2.44 (95% CI 1.37–4.33)] compared to non-exposed ever-smokers. The risk of non-smokers highly exposed to silica was not significantly increased [RR 1.07 (95% CI 0.72–1.58)] compared to non-exposed non-smokers.

Conclusion
The study indicates an increased risk of developing sarcoidosis in ever-smoking men exposed to silica.
Combined effects of elevated epilimnetic temperature and metalimnetic hypoxia on the predation rate of planktivorous fish

Published: August 2019

AbstractIncreased temperature in the epilimnion and hypoxia in the metalimnion of a lake would result in an increase of positive-size-selective fish predation on zooplankton and in turn in a decrease of mean body size in zooplankton populations and communities. We tested this hypothesis in four types of experiments with juvenile rudd (Scardinius erythrophthalmus) foraging on Daphnia longispina in an indoor twin column tank system. In each experiment of the first three types, one column contained one of three types of experimental treatments differing from the control treatment (in the other column) by the following: (i) elevated temperature in the epilimnion, (ii) hypoxia in the metalimnion and (iii) simultaneous elevated temperature in the epilimnion and hypoxia in the metalimnion. In the fourth type of experiment, the gradients of temperature and oxygen concentration in both columns were the same, but prior to the experiments, Daphnia and fish in the control treatment were acclimated to normoxia and, in the experimental treatment, to hypoxia. The results confirmed our hypothesis, since the predation rate of fish was greater in each of the first three experimental treatments than in the control. We did not detect an effect of the acclimation to hypoxia on the predation rate of the fish.
Developing an evaluation framework for university-driven technology-based, innovation for inclusive development (UTI4ID) projects
Authors: Botha L , Grobbelaar S S , Bam W G 
Published: August 2019

AbstractFrom the evaluation literature related to research and innovation policy, calls have long been made for improved evaluation processes especially where projects and programmes may be evaluated from a systems perspective. Drawing on the literature of innovation systems and innovation for inclusive development (I4ID) this research proposes a state-of-the-art analysis framework, which can be used to evaluate University-driven Technology-based Innovation for Inclusive Development (UTI4ID) projects. In particular, this framework draws on 16 exploratory case studies of UTI4ID that leads to the development of typologies that can be used in future UTI4ID evaluations to better guide such efforts. We thus not only show that advances in the I4ID literature provides an ideal starting point for complexity cognisant evaluations, but also contribute an end-to-end framework to support such evaluations and populate a detailed guide for future UTI4ID projects.
Global Political Uncertainty and Asset Prices
Authors: Brogaard Jonathan , Dai Lili , Ngo Phong T H , Zhang Bohui 
Published: August 2019

Abstract
We show that global political uncertainty, measured by the U.S. election cycle, on average, leads to a fall in equity returns in fifty non-U.S. countries. At the same time, market volatilities rise, local currencies depreciate, and sovereign bond returns increase. The effect of global political uncertainty on equity prices increases with the level of uncertainty in U.S. election outcomes and a country’s equity market exposure to foreign investors, but does not vary with the country’s international trade exposure. These findings suggest that global political uncertainty increases investors’ aggregate risk aversion, leading to a flight to safety.(JEL F30, F36, G12, G15, G18)

Published: August 2019

Abstract

Objectives
Expression of α4β7 integrin can identify gut-homing immune cells. This study aimed to determine the expression of Toll-like receptor 2 (TLR2) and TLR4 in α4β7-positive leukocytes of patients with axial SpA (axSpA).

Methods
We analysed the frequencies of α4β7-positive T cells, Tγδ cells and monocytes in 14 patients with axSpA and 14 healthy controls, together with the expression of TLR2 and TLR4 by flow cytometry. Also, the concentration of faecal calprotectin was measured in all patients and controls.

Results
We found significantly higher percentages of α4β7-positive T (P = 0.026) and Tγδ cells (P = 0.0118) in the patients with axSpA than in controls; these cells showed differential expression of TLR2 and TLR4 when compared with α4β7-negative cells. Such differences were not correlated with disease activity or faecal calprotectin concentration.

Conclusion
There is an increase in circulating α4β7-positive T and Tγδ cells in patients with axSpA. These cells differentially express TLR2 and TLR4.
Knockin’ on heaven’s door? Reframing the debate on temporary employment and wages: evidence from Europe
Authors: Bellani Daniela , Bosio Giulio 
Published: August 2019

AbstractThis article reframes the debate on the consequences of flexibilization in European labour markets focusing on the unexplored impact of temporary employment on occupational wages for permanent workers. Exploiting the variation in the temps’ density within occupation and age groups across European countries between 2003 and 2010, we find that temporary contracts negatively affect occupational average wages for insiders’ workers. These results are still robust using a dynamic system based on generalized method of moments (GMM-SYS) to account for potential endogeneity issues. We also explore the existence of heterogeneity across different occupational clusters and institutional settings. Our estimates indicate that the knock-on effect is large in countries with low employment protection legislation and it is driven by occupations characterized by untechnical work logics.

Authors: Hostetter Trisha A. , Hoffmire Claire A. , Forster Jeri E. , Adams Rachel Sayko , Stearns-Yoder Kelly A. , Brenner Lisa A. 
Published: August 2019

Objective:
Examine associations between traumatic brain injury (TBI) and (1) suicide and (2) suicide method among individuals receiving Veterans Health Administration (VHA) care.

Setting:
VHA, Fiscal Years 2006-2015.

Participants:
Veterans with a TBI diagnosis during/prior to the study window (n = 215 610), compared with a 20% random sample of those without TBI (n = 1 187 639).

Design:
Retrospective, cohort study. Cox proportional hazards models were fit accounting for time-dependent measures, chronic conditions, and demographics for those with TBI compared with those without. Additional models evaluated the impact of TBI severity on the association between TBI and suicide, and method.

Main Outcome Measures:
Death by and method of suicide.

Results:
The hazard of suicide was 2.19 times higher for those with TBI than for those without TBI (95% CI = 2.02-2.37), and was still significant after accounting for covariates (hazard ratio [HR] = 1.71; 95% confidence interval [CI] = 1.56-1.87). Considering severity, mild TBI compared with no TBI was significantly associated with an elevated hazard of suicide, after adjusting for covariates (HR = 1.62; 95% CI = 1.47-1.78). There was also a significant difference in death by suicide between moderate/severe TBI when compared with no TBI, after adjusting for covariates (HR = 2.45; 95% CI = 2.02-2.97). Moderate/severe TBI was significantly associated with an increase in the odds of suicide by firearm among decedents (odds ratio = 2.39; 95% CI = 1.48-3.87).

Conclusion:
Traumatic brain injury is associated with an elevated risk for suicide. Particular concern is warranted for those with moderate/severe TBI. Lethal means safety should be explored as an intervention.
Tear Proteases and Protease Inhibitors: Potential Biomarkers and Disease Drivers in Ocular Surface Disease
Authors: Fu Runzhong , Klinngam Wannita , Heur Martin , Edman Maria C. , Hamm-Alvarez Sarah F. 
Published: August 2019

Abstract:
Tears are highly concentrated in proteins relative to other biofluids, and a notable fraction of tear proteins are proteases and protease inhibitors. These components are present in a delicate equilibrium that maintains ocular surface homeostasis in response to physiological and temporal cues. Dysregulation of the activity of protease and protease inhibitors in tears occurs in ocular surface diseases including dry eye and infection, and ocular surface conditions including wound healing after refractive surgery and contact lens (CL) wear. Measurement of these changes can provide general information regarding ocular surface health and, increasingly, has the potential to give specific clues regarding disease diagnosis and guidance for treatment. Here, we review three major categories of tear proteases (matrix metalloproteinases, cathepsins, and plasminogen activators [PAs]) and their endogenous inhibitors (tissue inhibitors of metalloproteinases, cystatins, and PA inhibitors), and the changes in these factors associated with dry eye, infection and allergy, refractive surgery, and CLs. We highlight suggestions for development of these and other protease/protease inhibitor biomarkers in this promising field.
