Optimization of Parameters for Electrospinning of Polyacrylonitrile Nanofibers by the Taguchi Method
Authors: Celep G. K. , Dincer K. 
Published: August 2017

Abstract
This study empirically examined the influences of electrospinning process factors (applied voltage, feed rate of the polymer solution and tip-to-collector distance) and the polymer solution concentration on the diameters of electrospun polyacrylonitrile (PAN) nanofibers. To examine this, the polymer solution concentration, applied voltage, feed rate of the polymer solution and tip-to-collector distance were specified as parameters with four levels. In order to optimize these parameters, Taguchi's L16 orthogonal design (4 parameters, 4 levels) was applied to the experiential design. In order to describe the optimum production conditions for electrospun PAN nanofibers, the signal-to-noise (S/N) ratio was used, which was calculated from the diameters of electrospun PAN nanofibers using the “smaller-the-better” approach. By using the S/N ratio response results, the most influential parameter determining the nanofiber diameter was identified as the polymer solution concentration. The nanofiber diameter at the optimum conditions was 163.6 nm. In addition, homogeneous nanofibers with no observed beads were obtained by means of the newly designed adjustable rotary plate collector. In conclusion, the Taguchi technique was seen to be an efficient technique to optimise the crucial electrospinning process factors used in nanofiber production.

Abstract
Herein, we describe the synthesis of polyfuran, polyaniline, and their copolymer nanocomposites by in-situ oxidative polymerisation of corresponding monomers in the presence of montmorillonite, using ammonium persulfate as an oxidant. The obtained nanocomposites were characterised by Fourier-transform infrared spectroscopy, X-ray diffraction analysis, and UV-vis spectroscopy.

Published: August 2017

Background: As master regulator of embryonic morphogenesis, homeodomain-containing gene 10 (HOXC10) has been found to promote progression of human cancers and indicates poor survival outcome. However, the role of HOXC10 in lung adenocarcinoma still unclear.Methods: HOXC10 expression was evaluated in 63 primary lung adenocarcinoma tissues from our local hospital, and further systematically confirmed in lung cancer tissues from six GEO datasets (GSE19188, GSE31210, GSE10072, GSE7670, GSE32863, GSE30219), and Kaplan-Meier plotter database. The role of HOXC10 in lung cancer metastasis was further validated by cellular and molecular studies.Results: The expression of HOXC10 was significantly increased in human lung adenocarcinoma samples from Wuhu No.2 People's Hospital, about 4.219 times compared with normal tissues, and significantly correlated with TNM stage, lymph node, and distal metastasis. Upregulation of HOXC10 indicated a poor overall/relapse free survival of lung cancer patients from Wuhu No.2 People's Hospital, GEO datasets, and Kaplan-Meier plotter database, especially in patients with lung adenocarcinoma. Knockdown or ectopic expression assays confirmed that HOXC10 enhanced the phosphorylation of PI3K, regulated the expression of epithelial-to-mesenchymal transition (EMT) markers: MMP2/9, VCAM-1, vimentin and E-cadherin. Cellular study further confirmed that HOXC10 was required for migration, invasion and adhesion of lung cancer cells.Conclusion: These findings suggest that HOXC10 plays a pivotal role in the metastasis of human lung cancer and highlight its usefulness as a potential prognostic marker or therapeutic target in human lung adenocarcinoma.

Background Simple and low-cost tools to monitor the risk profile of patients on peritoneal dialysis (PD) at high risk of complications and mortality are scarce. One of the tools available to monitor the variation in vitality and dependence levels is the Karnofsky performance status (KPS). This study analyzed the average trends and variation of KPS during the 12 months before death and its independent value in predicting patients’ survival. Methods The data were compiled from the BRAZPD II multi-center study, performed in Brazil between 2004 and 2011. For the analysis of KPS dynamics, we included patients with at least 12 months of follow-up on PD and who had a fatal event during the follow-up. The following covariables were evaluated: age, gender, ethnicity, educational level, and presence of diabetes. We used the linear regression model to present the results: the log (time) before death was represented by the regression variable and KPS was the response. We also analyzed the independent impact of baseline KPS on patients’ survival. Results From the population of 9,905 patients enrolled in the BRAZPD study, 4,133 survived 12 months on PD and were included in the analysis. There was a gradual decline in the KPS scores, which accelerated in the last 2 months before death. These changes were similar irrespective of age, race, family income, gender, diabetes, PD modality, and education level. We observed 989 fatal events in this population during the observation period, and the KPS score was identified as an independent predictor for mortality in this cohort. Conclusions This study demonstrates for the first time the dynamics of KPS before death in PD patients, indicating a progressive and accelerated decline of KPS in the 12 months before patients died. In addition, KPS was an independent predictor of mortality in this population.

Background Bone is known to be impaired in chronic kidney disease and dialysis patients. Recent studies have shown that body composition (fat mass and lean mass) may impact bone health. Some of these effects may be related to mediators that are secreted by adipose tissue. Methods The aim of this study was to evaluate the association between body composition (dual x-ray absorptiometry [DEXA]) and adipokines (leptin, adiponectin), with bone density and microarchitecture assessed with high-resolution peripheral quantitative computed tomography (HR-pQCT) in chronic peritoneal dialysis (PD) patients in a single-center prospective study. Results Twenty-three patients with a median age of 61 years and body mass index (BMI) of 27 kg/m2 were recruited. On univariate analysis, age was negatively associated with total volumetric bone mineral density (vBMD) ( r = -0.75, p < 0.01), cortical vBMD ( r = -0.85, p < 0.01), and cortical thickness ( r = -0.71, p < 0.01). There was a negative association between leptin and cortical thickness ( r = -0.48, p = 0.021). Fat mass (FM) was negatively correlated with cortical thickness ( r = -0.52, p = 0.012). No association was found between bone parameters and dialysis duration, serum insulin, intact parathyroid hormone, osteocalcin, and adiponectin. The short dialysis vintage could in part explain the lack of correlation with bone parameters. In multivariate analysis, FM was significantly and negatively correlated with total vBMD, cortical and trabecular thickness. Conclusions These data suggest that FM is negatively associated with bone quality in PD patients, supporting a relation between body composition and bone that is independent from other dialysis-associated complications. The relative contribution of the different fat deposits (visceral versus subcutaneous) needs to be assessed in future studies.

Background Worldwide, approximately 11% of patients on dialysis receive peritoneal dialysis (PD). Whilst PD may offer more autonomy to patients compared with hemodialysis, patient and caregiver burnout, technique failure, and peritonitis remain major challenges to the success of PD. Improvements in care and outcomes are likely to be mediated by randomized trials of innovative therapies, but will be limited if the outcomes measured and reported are not important for patients and clinicians. The aim of the Standardised Outcomes in Nephrology-Peritoneal Dialysis (SONG-PD) study is to establish a set of core outcomes for trials in patients on PD based on the shared priorities of all stakeholders, so that outcomes of most relevance for decision-making can be evaluated, and that interventions can be compared reliably. Methods The 5 phases in the SONG-PD project are: a systematic review to identify outcomes and outcome measures that have been reported in randomized trials involving patients on PD; focus groups using nominal group technique with patients and caregivers to identify, rank, and describe reasons for their choice of outcomes; semi-structured key informant interviews with health professionals; a 3-round international Delphi survey involving a multi-stakeholder panel; and a consensus workshop to review and endorse the proposed set of core outcome domains for PD trials. Discussion The establishment of 3 to 5 high-priority core outcomes, to be measured and reported consistently in all trials in PD, will enable patients and clinicians to make informed decisions about the relative effectiveness of interventions, based upon outcomes of common importance.
To Epenthesize or Not? Adaptations of English Coda [m] in Standard Mandarin Loanwords
Authors: Huang Ho-Hsin , Lin Yen-Hwei 
Published: August 2017

This study investigates how English coda [m] is adapted into Standard Mandarin (SM) loanwords both in the existing corpora and in perceptual similarity adaptation data from monolingual SM and bilingual SM-English speakers. The nasal [m] in coda position is prohibited in SM. Deletion, nasal place change ([m]-->[n]/[ŋ]) and vowel epenthesis are the possible repair strategies. The generalizations identified in the corpora indicate that deletion never occurs (cf. Preservation Principle from Paradis 1996, Paradis & Lacharité 1997). Vowel epenthesis appears in SM when English coda [m] is in word-medial and word final positions. Nasal place change appears when English coda [m] is followed by a labial obstruent. Variable adaptations happen when English coda [m] is followed by an obstruent. The experimental results show that (i) the bilingual experimental strategies for nonce word adaptations are similar to the patterns observed in the SM loanwords corpora and (ii) monolinguals’ adaptation patterns are more variable due to greater dependence on perceptual cues. The fact that monolinguals and bilinguals differ in the extent to which they employ perceptual cues and phonological features/constraints for loanword adaptations challenges a pure perception-based account of loanword adaptation.
No More Conflicting Directionality:Metrical Conditions on Tianjin Chinese Trisyllabic Tone Sandhi
Authors: Wang Xiaomei , Lin Yen-Hwei 
Published: August 2017

Abstract Tianjin Chinese (hereafter Tianjin) exhibits complex interactions among its disyllabic tone sandhi rules, leading to both left-to-right and right-to-left rule applications in trisyllabic sequences (e.g. Chen 1986, X. Wang 2003, Lin 2008). Which directionality to adopt for each particular sequence is arbitrary and cannot be accounted for by any known principles. In addition, some disyllabic tone sandhi rules do not always apply in trisyllabic sequences. Based on the results of a multi-speaker acoustic study, we propose that both issues can be attributed to interactions of metrical structures, sandhi rules, and tonal complexity. We claim that Tianjin tone sandhi applies when both metrical and tonal complexity conditions are satisfied, thereby removing the need for conflicting directionality.
Phonological Trends in Seoul Korean Compound Tensification
Authors: Kim Seoyoung 
Published: August 2017

This study investigates Seoul Korean compound tensification. Based on the data collected through a survey, it shows that various phonological factors contribute to the overall tensification probability. The tendencies caused by these factors are follows: (i) tensification is more likely with high frequency items; (ii) tensification is more likely when WA ends with an obstruent, followed by a nasal, liquid and a vowel in order; (iii) tensification is less likely when WB contains a laryngeally marked consonant; (iv) tensification is more likely when WB ends with a liquid and WA also begins with a coronal consonant. This study also provides a formal analysis of this phenomenon, using OT constraints. The specific weights of each constraint are evaluated through Maxent Grammar Tool. This weighted set of the constraints was highly successful in predicting the applicability of compound tensification. Thus, the grammar suggested for Seoul Korean compound tensification can be learned from the actual native speakers’ pronunciation data, and also that this learned grammar can capture the various tendencies observed in this phenomenon.
Looking into Segments
Authors: Inkelas Sharon , Shih Stephanie S 
Published: August 2017

This paper outlines Q theory, in which the traditional segment (consonant, vowel) is decomposed into a string of three ordered subsegments, or q, representing the onset, target, and offset of the segment. The postulation of subsegmental structure permits the representation of complex (contour) segments as well as subtle contrasts in segment-internal changes of state. Q Theory synthesizes insights from Autosegmental Phonology, Aperture Theory, and Articulatory Phonology in a representation that standard phonological constraints can refer to. Q theory is supported by arguments that subsegments act independently and need to be independently referenced by the phonological grammar. Embedded into Agreement by Correspondence Theory, Q theory permits the analysis of contour assimilation as well as contour formation, both in the tonal and segmental domains.
Alternatives to Stricture-Driven Assimilation
Authors: Brown Jason 
Published: August 2017

Sequences of nasals followed by fricatives have proven to be a special case of marked structures, triggering repairs that are not enforced with other sequences, such as nasals followed by stops. Most analyses of nasal+fricative sequences assume stops and nasals share the value [-cont], and nasals and fricatives are mismatched for the value of the feature. This mismatch is thought to be the source of the markedness of this configuration. This short paper engages the possibility that nasals in some languages have the opposite value for the feature continuant, which predicts that they are in conflict with the value for stops in these languages. The further prediction is that in these languages, fricatives should exhibit assimilation, but stops will trigger other repairs. A case study from Finnish indicates that this is not the case: as normally happens, stops undergo place assimilation, but fricatives either resist assimilation, or undergo other repairs.
Vowel Length in Nuer
Authors: Monich Irina Vitta 
Published: August 2017

Here we examine newly collected Nuer data to show that Western Nilotic language Nuer distinguishes three degrees of vowel length. A minimal triplet cak ‘tick.SG.NOM” ~ ca:k “milk.PL.NOM” ~ ca::k “milk.PL.GEN” provides an example of this contrast. Since vowel length plays a crucial role in nominal inflection, we examine distribution of the three degrees of vowel length in the nominal paradigm. Our preliminary conclusion is that Nuer vowels are lexically specified for two degrees of vowel length only – short and long, and that overlong vowels emerge only as an outcome of a morphological operation which lengthens short and long vowels. Since we conclude that the three degrees of vowel length do not have equal status in the Nuer grammar, our findings therefore are in line with the reported typological markedness of the three-way contrast in vowel length.

Abstract
We report new dynamical masses for five pre-main sequence (PMS) stars in the L1495 region of the Taurus star-forming region (SFR) and six in the L1688 region of the Ophiuchus SFR. Since these regions have VLBA parallaxes, these are absolute measurements of the stars’ masses and are independent of their effective temperatures and luminosities. Seven of the stars have masses

, thus providing data in a mass range with little data, and of these, six are measured to precision

. We find eight stars with masses in the range 0.09–1.1

that agree well with the current generation of PMS evolutionary models. The ages of the stars we measured in the Taurus SFR are in the range 1–3 Myr, and

Myr for those in L1688. We also measured the dynamical masses of 14 stars in the ALMA archival data for Akeson & Jensen’s Cycle 0 project on binaries in the Taurus SFR. We find that the masses of seven of the targets are so large that they cannot be reconciled with reported values of their luminosity and effective temperature. We suggest that these targets are themselves binaries or triples.
Detection of a Large Population of Ultradiffuse Galaxies in Massive Galaxy Clusters: Abell S1063 and Abell 2744

Published: August 2017

Abstract
We present the detection of a large population of ultradiffuse galaxies (UDGs) in two massive galaxy clusters, Abell S1063 at z = 0.348 and Abell 2744 at z = 0.308, based on F814W and F105W images in the Hubble Frontier Fields Program. We find 47 and 40 UDGs in Abell S1063 and Abell 2744, respectively. Color–magnitude diagrams of the UDGs show that they are mostly located at the faint end of the red sequence. From the comparison with simple stellar population models, we estimate their stellar mass to range from 108 to 109

From Neutron Star Observables to the Equation of State. II. Bayesian Inference of Equation of State Pressures
Authors: Raithel Carolyn A. , Özel Feryal , Psaltis Dimitrios 
Published: August 2017

Abstract
One of the key goals of observing neutron stars is to infer the equation of state (EoS) of the cold, ultradense matter in their interiors. Here, we present a Bayesian statistical method of inferring the pressures at five fixed densities, from a sample of mock neutron star masses and radii. We show that while five polytropic segments are needed for maximum flexibility in the absence of any prior knowledge of the EoS, regularizers are also necessary to ensure that simple underlying EoS are not over-parameterized. For ideal data with small measurement uncertainties, we show that the pressure at roughly twice the nuclear saturation density,

, can be inferred to within 0.3 dex for many realizations of potential sources of uncertainties. The pressures of more complicated EoS with significant phase transitions can also be inferred to within ∼30%. We also find that marginalizing the multi-dimensional parameter space of pressure to infer a mass–radius relation can lead to biases of nearly 1 km in radius, toward larger radii. Using the full, five-dimensional posterior likelihoods avoids this bias.

Abstract
We present a new upper limit on cosmic microwave background (CMB) circular polarization from the 2015 flight of Spider, a balloon-borne telescope designed to search for B-mode linear polarization from cosmic inflation. Although the level of circular polarization in the CMB is predicted to be very small, experimental limits provide a valuable test of the underlying models. By exploiting the nonzero circular-to-linear polarization coupling of the half-wave plate polarization modulators, data from Spider's 2015 Antarctic flight provide a constraint on Stokes V at 95 and 150 GHz in the range
