On the Pragmatic Turn in Political Philosophy
Authors: Skoble Aeon J. 
Published: August 2020

Abstract
Imagine some policy P about which a scholar said “The best way to help people escape from poverty would be P.” Is this a claim about political philosophy or economics? On the one hand, it seems to be an empirical statement, but there is a normative component as well. Besides the obvious normativity of “best,” there is the tacit implication that poverty is bad and that this is at least some reason to endorse P. But the fact that one can easily imagine either a political philosopher or an economist making the claim points to one reason for the recent growth of programs in Philosophy, Politics, and Economics (PPE), programs of study which emphasize the interdisciplinary connection between political philosophy and the social sciences. Political philosophy is, of course, philosophy, which means it is a combination of analytic and normative tools, but since its subject matter involves human behavior and social institutions, empirical study of those seems like it should be relevant as well. Since political philosophy addresses questions about the social order, findings from the social sciences are surely relevant, chiefly from economics and political science. At first glance this seems directly analogous to the way philosophy of cognitive science would find relevance from work in neurology. But social scientists are themselves often beholden to normative priors which frame their methodology. The increased popularity of and growth of programs in PPE is therefore definitely beneficial both to the philosophers and to the social scientists who explore these issues. However, while the empirical is relevant, and, I would argue, essential, to good work in political philosophy, I would resist the suggestion that the empirical is exhaustive and that the philosophical is either superfluous or unwarranted.
Convergence analysis of a variational quasi-reversibility approach for an inverse hyperbolic heat conduction problem
Authors: Khoa Vo Anh , Dao Manh-Khang 
Published: August 2020

Abstract
We study a time-reversed hyperbolic heat conduction problem based upon the Maxwell–Cattaneo model of non-Fourier heat law. This heat and mass diffusion problem is a hyperbolic type equation for thermodynamics systems with thermal memory or with finite time-delayed heat flux, where the Fourier or Fick law is proven to be unsuccessful with experimental data. In this work, we show that our recent variational quasi-reversibility method for the classical time-reversed heat conduction problem, which obeys the Fourier or Fick law, can be adapted to cope with this hyperbolic scenario. We establish a generic regularization scheme in the sense that we perturb both spatial operators involved in the PDE. Driven by a Carleman weight function, we exploit the natural energy method to prove the well-posedness of this regularized scheme. Moreover, we prove the Hölder rate of convergence in the mixed

Published: August 2020

Abstract
Tennis is one of the most popular and widely played sports enjoyed by players of different age groups and genders as a profession as well as a mode of recreation. A novel method, PETTLEP imagery combines both conventional and non-conventional style of training of an athlete and improves one’s performance. This study aimed to analyze the tennis service performance of junior tennis players based on PETTLEP imagery training. Forty-four junior male tennis players (M
age=13.22 years, SD=0.42) were selected for the study. The investigator handed over the MIQ-R questionnaire to all the participants in which they scored 16 and above points as per previous research. The participants were equally divided (n=11) into three experimental groups (E1, E2, and E3) and a control group. The service performance outcomes of all the players were compared before and after a training session. The three experimental groups were assigned with service-specific training, service-specific training combined with PETTLEP imagery training, and PETTLEP imagery training alone, respectively, for three days per week for 12 weeks. They were tested on their service accuracy based on the International tennis number (ITN) manual on-court assessment test. The data were assessed for normality and analyzed using non-parametric methods to reveal main effects (each training method alone) as well as to calculate the combined effect of PETTLEP and service-specific training. Certain significant improvements in tennis service were observed with service-specific training alone. Though it marginally outperformed the PETTLEP imagery method, the most improved services were observed with both PETTLEP and service-specific training utilized together. This implies an additive effect when both methods are used together.
Effect of sintered electrode on microhardness and microstructure in electro discharge deposition of magnesium alloy
Authors: Elaiyarasan U. , Satheeshkumar V. , Senthilkumar C. 
Published: August 2020

Abstract
In this study, an endeavour have been made to depositing the electrode materials over the surface of the magnesium alloy using electrical discharge machining (EDM) with WC-Cu powder compacted sintered electrode. Various process parameters such as compaction load, discharge current and pulse on time are selected to carry out the experiment in order to attain the maximum material migration rate (MMR) or deposition rate and microhardness (MH). It was concluded that the MMR and MH increased with increase in discharge current and pulse on time at low compacted electrode but it is decreased at lower discharge current and pulse on time. Highest MMR and MH were attained successfully at partial sintered low compaction load electrode. Microstructure evaluation has been carried out on deposited surface using scanning electron microscopy (SEM) and presence of electrode element in the deposited surface was confirmed by energy dispersive spectroscopy (EDS). Defects mechanism such as globules and craters are formed during EDC with high current and pulse on time respectively, which diminishes the surface roughness. It was observed that the compaction load is the influence parameter on the MMR and MH.
Proactive link handover deploying coordinated transmission for indoor visible light communications (VLC) networks
Authors: Tran Cong-Nam , Hoang Trong-Minh , Nguyen Nam-Hoang 
Published: August 2020

Abstract
Visible Light Communications (VLC) is considered as an emerging technology for indoor wireless communications to achieve high-speed and secure data transmission. Instead of using radio frequency (RF) spectrum, VLC uses the visible light spectrum to perform lighting and communications functions simultaneously. Multiple access points VLC (multi-AP VLC) networks use ceiling access point (ceiling-AP) and desk access point (desk-AP) to provide both uniform and spot lighting in order to achieve full coverage and high spectral efficiency. Because mobile user equipment (UE) require seamless connectivity when moving, fast link handover between VLC access points (VLC-AP) has to be supported in the VLC networks. In this paper, we present a coordinated multi-channel transmission method (CMcT) used to improve quality of service (QoS) of cell-edge UEs and propose a novel proactive link handover scheme deploying the CMcT method for multi-AP VLC networks. Performance results obtained by computer simulation show that the proactive link handover scheme deploying the CMcT method can significantly improve user throughput and packet delay comparing with those of other link handover schemes.

Published: August 2020

Abstract
In this work, photonic crystal (PhC) based all-optical 1 × 2 demultiplexer is designed for optical computing and optical signal processing. The structure is implemented with two-dimensional PhCs using T-shaped waveguides with an optimized silicon rod radius of 0.2a. Performance of the proposed structure is verified and analyzed by using the finite-difference time-domain method. The design of all-optical demultiplexer is operated based on optical interference effect at a wavelength of 1550 nm. Proposed design occupies less area of 8.4 × 5.4 µm, provides a contrast ratio of 18.53 dB, 94.52% of minimum and 100% of maximum transmission ratio and it has less insertion loss of 0.017 dB; therefore, the proposed device is suitable for photonic integrated devices.
Analysis the flat gain/noise figure using RAMAN-Reflective Semiconductor Hybrid Optical Amplifier in C + L + U triple band for super dense wavelength division multiplexing system
Authors: Kumar Chakresh , Kumar Ghanendra 
Published: August 2020

Abstract
Nonlinearity, flat gain and noise figure are the prime concern for super dense wavelength division multiplexing (SD-WDM) systems which have been resolved from RAMAN-RSOA hybrid optical amplifier (HOA) for the first time in this paper. Channel capacity is taken up to 400 with data rate of 10 Gbps. Performances are evaluated with respect to C + L + U band for 1520–1680 nm and 1520 to 1640 nm. RSOA is operated at 40–120 mA bias current to attain best rating flat gain of 34.07 dB with variation of 3.5 dB than the others HOAs (RAMAN-EDFA, RAMAN-SOA and EDFA-SOA). Moreover, the impact of EDFA-SOA is not acceptable in terms of noise figure for SD-WDM optical communication system.

Published: August 2020

AbstractObjectivesTo determine whether there is a cut off value of serum C-reactive protein (CRP) associated with a higher risk of meningitis in suspected early onset sepsis (EOS) (onset birth to 7 days of life).MethodsA retrospective cohort study on neonates admitted in neonatal intensive care unit at McMaster Children’s Hospital from January 2010 to 2017 and had lumbar puncture (LP) and CRP for workup of EOS. Included subjects had either (a) non-traumatic LP or (b) traumatic LP with cerebral spinal fluid (CSF) polymerase chain reaction or gram stain or culture-positive or had received antimicrobials for 21 days. Excluded were CSF done for metabolic errors, before cytomegalovirus (CMV) treatment; from ventriculo-peritoneal (VP) shunts; missing data and contamination. Neonates were classified into definite and probable meningitis and on the range of CRP. We calculated sensitivity, specificity, and likelihood ratios for CRP values; and area under the receiver operating characteristic (AUROC) curve.ResultsOut of 609 CSF samples, 184 were eligible (28 cases of definite or probable meningitis and 156 controls). Sensitivity, specificity, predictive values, likelihood ratios, and AUROC were too low to be of clinical significance to predict meningitis in EOS.ConclusionsSerum CRP values have poor discriminatory power to distinguish between subjects with and without meningitis, in symptomatic EOS.
Furcate insertion of the umbilical cord: pathological and clinical characteristics in 132 cases
Authors: Kosian Philipp , Henrich Wolfgang , Entezami Michael , Weichert Alexander 
Published: August 2020

Abstract

Objectives
Furcate cord insertion is a rare abnormality affecting approximately 0.1% of all pregnancies. Macroscopically, the umbilical vessels separate before reaching the placenta, lose their Wharton’s jelly, and insert at the placenta centrally, eccentrically, or marginally. The aim of this retrospective study was to determine the prevalence of furcate cord insertion more accurately, the pathological characteristics, and clinical outcomes.

Methods
We conducted a retrospective study of 132 cases of furcate insertion of the umbilical cord using the pathological database of the Charité University Hospital Berlin, Germany, between 1993 and 2016. This included 99 cases, including one termination of pregnancy within our institution and 33 cases from external hospitals. An analysis of the pathological features of the 132 cases and the perinatal outcome of the 98 cases within our institution were performed.

Results
Furcate cord insertion occurred in 0.16% pregnancies. Of the 132 cases, seven cases of intrauterine fetal deaths were observed. Three of those could be linked to the furcate cord insertion. In two of those cases, single umbilical vessel rupture was identified as the cause of fetal death.

Conclusions
In most cases of furcate cord insertion, the outcome is good; however, intrauterine fetal death occurs in approximately 1.02% of cases.
Functional ratings in sports
Authors: Lowery Brad , Slater Abigail , Thies Kaison 
Published: August 2020

Abstract
In this paper, we present a new model for ranking sports teams. Our model uses all scoring data from all games to produce a functional rating by the method of least squares. The functional rating can be interpreted as a team average point differential adjusted for strength of schedule. Using two team’s functional ratings we can predict the expected point differential at any time in the game. We looked at three variations of our model accounting for home-court advantage in different ways. We use the 2018–2019 NCAA Division 1 men’s college basketball season to test the models and determined that home-court advantage is statistically important but does not differ between teams.

Authors: Martin Carina Rey , Rodriguez-Parada Concepción , Pacios Ana R. , Vianello Osti Maria , Bravo Blanca Rodriguez 
Published: August 2020

Abstract
Transparency in the management of 50 Spanish public university libraries was analysed using information available on their websites. The method consisted of checking the websites to identify a set of 18 evaluation indicators associated with the specific case of libraries and the Spanish Transparency Act, notably the chapter on active publishing. The indicators have been used in previous studies with the same objective. The results of the analysis revealed shortcomings, although there were also examples of good practises for each indicator, identified with libraries that have introduced quality systems for management. The indicators that were found most frequently in the sample were regulations, specific regulations for some services and service charters. However, the sample lacked some indicators that are vital to understand the reasons behind the development and management of information resources, such as the policy or programme of collection management. We found a need to review the quantity and quality of information that can be consulted on libraries’ websites, and the presentation and format of some types of information so that they can be reused.
Understanding population baselines: status of mountain ungulate populations in the Central Tien Shan Mountains, Kyrgyzstan
Authors: Khanyari Munib , Zhumabai uulu Kubanychbek , Luecke Suraiya , Mishra Charudutt , Suryawanshi Kulbhushansingh Ramesh 
Published: August 2020

AbstractWe assessed the density of argali (Ovis ammon) and ibex (Capra sibirica) in Sarychat-Ertash Nature Reserve and its neighbouring Koiluu valley. Sarychat is a protected area, while Koiluu is a human-use landscape which is a partly licenced hunting concession for mountain ungulates and has several livestock herders and their permanent residential structures. Population monitoring of mountain ungulates can help in setting measurable conservation targets such as appropriate trophy hunting quotas and to assess habitat suitability for predators like snow leopards (Panthera uncia). We employed the double-observer method to survey 573 km2of mountain ungulate habitat inside Sarychat and 407 km2inside Koiluu. The estimated densities of ibex and argali in Sarychat were 2.26 (95% CI 1.47–3.52) individuals km−2and 1.54 (95% CI 1.01–2.20) individuals km−2, respectively. Total ungulate density in Sarychat was 3.80 (95% CI 2.47–5.72) individuals km−2. We did not record argali in Koiluu, whereas the density of ibex was 0.75 (95% CI 0.50–1.27) individuals km−2. While strictly protected areas can achieve high densities of mountain ungulates, multi-use areas can harbour meaningful though suppressed populations. Conservation of mountain ungulates and their predators can be enhanced by maintaining Sarychat-like “pristine” areas interspersed within a matrix of multi-use areas like Koiluu.
Sequential change-point detection in a multinomial logistic regression model
Authors: Li Fuxiao , Chen Zhanshou , Xiao Yanting 
Published: August 2020

Abstract
Change-point detection in categorical time series has recently gained attention as statistical models incorporating change-points are common in practice, especially in the area of biomedicine. In this article, we propose a sequential change-point detection procedure based on the partial likelihood score process for the detection of changes in the coefficients of multinomial logistic regression model. The asymptotic results are presented under both the null of no change and the alternative of changes in coefficients. We carry out a Monte Carlo experiment to evaluate the empirical size of the proposed procedure as well as its average run length. We illustrate the method by using data on a DNA sequence. Monte Carlo experiments and real data analysis demonstrate the effectiveness of the proposed procedure.

Abstract
In this article, we study the nonlinear and nonsmooth interval-valued optimization problems in the face of data uncertainty, which are called interval-valued robust optimization problems (IVROPs). We introduce the concept of nondominated solutions for the IVROP. If the interval-valued objective function f and constraint functions

Estimating marginal likelihoods from the posterior draws through a geometric identity
Authors: Reichl Johannes 
Published: August 2020

Abstract
This article develops a new estimator of the marginal likelihood that requires only a sample of the posterior distribution as the input from the analyst. This sample may come from any sampling scheme, such as Gibbs sampling or Metropolis–Hastings sampling. The presented approach can be implemented generically in almost any application of Bayesian modeling and significantly decreases the computational burdens associated with marginal likelihood estimation compared to existing techniques. The functionality of this method is demonstrated in the context of probit and logit regressions, on two mixtures of normals models, and also on a high-dimensional random intercept probit. Simulation results show that the simple approach presented here achieves excellent stability in low-dimensional models, and also clearly outperforms existing methods when the number of coefficients in the model increases.
Constructing a confidence interval for the ratio of normal distribution quantiles
Authors: Malekzadeh Ahad , Mahmoudi Seyed Mahdi 
Published: August 2020

Abstract
In this paper, to construct a confidence interval (general and shortest) for quantiles of normal distribution in one population, we present a pivotal quantity that has non-central t distribution. In the case of two independent normal populations, we propose a confidence interval for the ratio of quantiles based on the generalized pivotal quantity, and we introduce a simple method for extracting its percentiles, based on which a shorter confidence interval can be created. Also, we provide general and shorter confidence intervals using the method of variance estimate recovery. The performance of five proposed methods will be examined by using simulation and examples.

Published: August 2020

Abstract
In December 2019, novel coronavirus pneumonia-19 (COVID-19) was discovered in the viral pneumonia cases that occurred in Wuhan, China, and then quickly spread around the world. This report described the clinical course of two COVID-19 patients and the purpose of the study was to discuss the combination of chest CT and clinical features for diagnosis of COVID-19. The first case was a typical COVID-19 case. A 66-year-old female presented to our hospital with a 3-day history of fever. She had contact with a COVID-19 patient. Chest CT showed a typical COVID-19 appearance. She was diagnosed with COVID-19 by a positive nucleic acid test. The second case was a 50-year-old male with a 2-day history of fever. He denied having been to Wuhan. Chest CT also showed typical features of COVID-19 pneumonia. COVID-19 nucleic acid tests were repeated up to seven times and the results remained controversial. Eventually, he was diagnosed with COVID-19. Our study shows that chest CT has high sensitivity for diagnosis of COVID-19 in clinical practice, particularly when the nucleic acid test is negative. The chest CT should be considered as a diagnostic tool for the COVID-19 screening, comprehensive evaluation, and follow-up and patients would benefit from effective treatments in time.
Hemoperitoneum caused by spontaneous rupture of hepatocellular carcinoma in noncirrhotic liver. A case report and systematic review

Published: August 2020

Abstract

Introduction
Hepatocellular carcinoma (HCC) is the sixth most common cancer. Spontaneous rupture of HCC is an acute complication with a high mortality rate. The HCC principally arises in the background of chronic liver disease and cirrhosis of the liver. In the last few years, the rising incidence of HCC in noncirrhotic liver suggests the presence of other factors that may play a role in liver carcinogenesis.

Methods
We reviewed all cases treated at the University Surgical Department of Ospedali Riuniti of Foggia from 2009 to 2018. Only a single case of hemoperitoneum caused by spontaneous rupture of HCC in noncirrhotic liver was found. An extensive search of the relevant literature was carried out using MEDLINE, and a total of 58 published studies were screened from the sources listed.

Conclusions
The management of this devastating emergency should be carefully analyzed, with stabilization of vital signs as soon as possible. Patient with ruptured HCC and hemoperitoneum without a prior history of cirrhosis and viral infections benefited from the role of transcatheter arterial embolization (TAE) as the preliminary treatment in order to have a more precise diagnosis and an optimal stabilization of the patient. Delayed or staged hepatectomy after TAE represents the definitive treatment.
