Starspot rotation rates versus activity cycle phase: Butterfly diagrams ofKeplerstars are unlike that of the Sun
Authors: Nielsen M. B. , Gizon L. , Cameron R. H. , Miesch M. 
Published: January 2019

Context. During the solar magnetic activity cycle the emergence latitudes of sunspots change, leading to the well-known butterfly diagram. This phenomenon is poorly understood for other stars since starspot latitudes are generally unknown. The related changes in starspot rotation rates caused by latitudinal differential rotation can, however, be measured.Aims. Using the set of 3093Keplerstars with measured activity cycles, we aim to study the temporal change in starspot rotation rates over magnetic activity cycles, and how this relates to the activity level, the mean rotation rate of the star, and its effective temperature.Methods. We measured the photometric variability as a proxy for the magnetic activity and the spot rotation rate in each quarter over the duration of theKeplermission. We phase-folded these measurements with the cycle period. To reduce random errors, we performed averages over stars with comparable mean rotation rates and effective temperature at fixed activity-cycle phases.Results. We detect a clear correlation between the variation of activity level and the variation of the starspot rotation rate. The sign and amplitude of this correlation depends on the mean stellar rotation and – to a lesser extent – on the effective temperature. For slowly rotating stars (rotation periods between 15 − 28 days), the starspot rotation rates are clearly anti-correlated with the level of activity during the activity cycles. A transition is observed around rotation periods of 10 − 15 days, where stars with an effective temperature above 4200 K instead show positive correlation.Conclusions. Our measurements can be interpreted in terms of a stellar “butterfly diagram”, but these appear different from that of the Sun since the starspot rotation rates are either in phase or anti-phase with the activity level. Alternatively, the activity cycle periods observed byKeplerare short (around 2.5 years) and may therefore be secondary cycles, perhaps analogous to the solar quasi-biennial oscillations.
Finite-time stability analysis of fractional differential systems with variable coefficients
Authors: Zhang Fengrong , Qian Deliang , Li Changpin 
Published: January 2019

In this paper, we study finite-time stability of fractional differential systems with variable coefficients, which includes the homogeneous and nonhomogeneous delayed cases. Based on the theories of fractional differential equations, we obtain three theorems on the finite-time stability, which give some sufficient conditions on finite-time stability, respectively, for homogeneous systems without and with time delay and for the nonhomogeneous system with time delay.

Significance
Neutropenia presents an important clinical problem in patients with G6PC3 or G6PT deficiency, yet why neutropenia occurs is unclear. We discovered that G6PC3 and G6PT collaborate to dephosphorylate a noncanonical metabolite (1,5-anhydroglucitol-6-phosphate; 1,5AG6P) which is produced when glucose-phosphorylating enzymes erroneously act on 1,5-anhydroglucitol, a food-derived polyol present in blood. In patients or mice with G6PC3 or G6PT deficiency, 1,5AG6P accumulates and inhibits the first step of glycolysis. This is particularly detrimental in neutrophils, since their energy metabolism depends almost entirely on glycolysis. Consistent with our findings, we observed that treatment with a 1,5-anhydroglucitol-lowering drug treats neutropenia in G6PC3-deficient mice. Our findings highlight that the elimination of noncanonical side products by metabolite-repair enzymes makes an important contribution to mammalian physiology.
Impoliteness and the moral order in online gaming
Authors: Lambert Graham Sage 
Published: January 2019

AbstractIn recent years, eSports, online gaming, and live computer game streaming have grown into a global, multi-million dollar industry. In the context of online gaming, however, there is a prevailingmoral order(Kádár 2017) that allows and perhaps even encourages impoliteness against female gamers, positioning them as inferior, unwelcome, or peripheral. Drawing from a corpus of over 150 hours of live game streams and concurrent open-forum chat, this paper identifies rituals and tropes (such as spam and banter) that reinforce gendered practices as they relate to the moral order in the online gaming setting. It then explores strategies used by one female gamer to manipulate the expectations of the online gaming medium and its hegemonic notions of femininity. In this way, she can resist a moral order which positions her as disempowered, and thereby gain social capital within the community.
The meta-conventionalisation and moral order of e-practices
Authors: Kádár Dániel Z. , Fukushima Saeko 
Published: January 2019

AbstractThis paper overviews the phenomenon of the meta-conventionalisation of interpersonal practices in the context of computer-mediated communication. The term ‘meta-conventionalisation’ refers to the coding of the conventional interpersonal practices of a particular group, or various groups, in the form of entertainment as films and novels. The word ‘meta’ refers to the fact that such pieces of artwork narrate a set of conventional practices from a quasi-observer point of view, without involving their audience in these practices as language users – in this sense they are different from good practice guides (typically described as ‘netiquette, in the context of e-pragmatics), which assume that readers will internalise the practices they describe. Meta-conventionalisation has been an understudied phenomenon, in spite of representing an important aspect of our daily lives. We illustrate how this phenomenon operates by examining a Japanese case study: a popular novel which features the online interactions of a group of otaku, that is, asocial young people who lock themselves up and interact in highly specific ways.

This report gives the results of the APMP.M.F-K2.a and APMP.M.F-K2.b key comparison in 50 kN and 100 kN force range. This regional key comparison was conducted under the Asia Pacific Metrology Program (APMP) to establish a link to the global CCM.F-K2 (http://iopscience.iop.org/article/10.1088/0026-1394/49/1A/07002/meta) key comparison.
13 laboratories participated in this key comparison. The Korea Research Institute of Standards and Science (KRISS) served as the pilot laboratory. The National Metrology Institute of Japan (NMIJ/AIST) and the National Metrology Institute (NIM) of China together with KRISS provided links to the CCM.F-K2.a and CCM.F-K2.b key comparison. Two pairs of force transducers of 50 kN and 100 kN nominal capacities were circulated among the participants in a star formation.
The final results suggest that the nominal 50 kN force generated at one laboratory and 100 kN force at another laboratory may be different from the CCM.F-K2 key comparison reference value.

Nine NMI/DI participated in the CCQM Organic Analysis WG Track C Key Comparison CCQM-K138 Determination of aflatoxins (AFB1, AFB2, AFG1, AFG2 and Total AFs) in Dried Fig. Participants were requested to evaluate the mass fractions expressed in ng/g units, of aflatoxins B1, B2, G1, G2 and total aflatoxin in a dried fig. Aflatoxins are part of the mycotoxin family of contaminants which are a major issue for the food production industry internationally.
The CCQM-K138 results ranged from 5.17 to 7.27 ng/g with an %RSD of 10.47 for AFB1, ranging from 0.60 to 0.871 ng/g with an %RSD of 11.69 for AFB2, ranging from 1.98 to 2.6 ng/g with an %RSD of 10.36 for AFG1, ranging from 0.06 to 0.32 ng/g with an %RSD of 35.6 for AFG2, and ranging from 8.29 to 10.31 ng/g with an %RSD of 7.69 for Total AFs. All participants based their analyses on Liquid Chromatography, seven utilizing LC-MS/MS with labelled internal standards and two utilizing HPLC-FLD. Linear Pool estimators were used to assign the Key Comparison Reference Values (KCRVs) for B1, B2, G1, G2 and total aflatoxins.
Successful participation in CCQM-K138 demonstrates the following measurement capabilities in determining mass fraction of organic compounds, with molecular mass of 100 g/mol to 500 g/mol, having high polarity (pKow > -2), in mass fraction range from 0.05 ng/g to 500 ng/g in dried food matrices. It was noted that the results for CCQM-K138 represent a highly challenging set of measurands and involve very low level measurement of complex analytes in a situation where there is very limited availability of appropriate calibration materials. Due to the variability in results the degrees of equivalence for these analytes were reasonably large and this will need to be taken into consideration in the assessment of proposed CMCs.

Linking dose delivery accuracy and planning target margin in radiosurgery based on dose-volume histograms derived from measurement-guided dose reconstruction

Published: January 2019

Abstract
In radiosurgery (SRS), the geometric uncertainties of machine-related delivery including image-guidance and hence the planning target volume (PTV) are often evaluated by the end-to-end gamma (γ) comparison that carries no information about the clinical relevance of deviations of individual SRS plans during delivery quality assurance (DQA). A proof-of-concept method was proposed to derive the PTV against both the plan- and the machine-specific delivery errors directly from the clinically relevant dose-volume histograms (DVHs) using measured-guided dose reconstruction (MGDR) during DQA. A liquid-filled detector array and a rotating phantom were used to measure sixteen arc-based radiosurgery treatments with 1 and 2 mm gross tumor volume (GTV)-to-PTV margins, producing MGDR-3D dose distribution on both the phantom and the patient CT for γ index and clinical DVH evaluations, respectively. The PTV was considered optimal when the MGDR showed the desired prescription dose coverage (V

pres
) of the GTV (100% in this study). Associations of the binary V

pres
outcomes (<or  =100%) of the GTV with the acceptance level of percent γ pass rate (γPR%) at 90 versus 95% were assessed. Further receiver operator characteristic (ROC) analysis was performed to assess the distance-to-agreement (DTA) and local dose difference (ΔD) criteria that may be suitable for treatment acceptance. From the MGDR, 100% GTV V

pres
was achieved in 68.8% and 100% of plans with 1 and 2 mm PTV, respectively. V

pres
outcomes were neither associated with γPR% at 1–2 mm DTA and 1%–3% ΔD nor the acceptance level for MGDR in the patient CT. ROC analysis shows statistically significant AUC values from 0.78–0.84 and 0.79–0.80 for MGDR phantom and patient doses, respectively. DQA by MGDR-DVH objectives offers the unique opportunity of direct assessment of the dose delivery accuracy and hence the optimal PTV without subject to the statistical correlation between γPR% and clinical metrics. Based on multi-criteria DVH objectives, clinical decision can be instantly made to adjust the treatment plan prescription.

Published: January 2019

Abstract

Objectives
To investigate biotin interference on three cardiac troponin (cTn) assays and demonstrate a method to overcome biotin interference.

Methods
cTn levels were measured in (1) plasma from healthy volunteers on 10-mg daily biotin supplementation mixed with a plasma with known elevated troponin, (2) plasmas with known elevated cTn after mixing in reagent biotin to simulate supplementation, and (3) biotin-spiked plasma specimens pretreated with streptavidin-agarose beads.

Results
Daily biotin ingestion (10 mg) and studies simulating daily biotin use resulted in significant interference in the Gen5 cardiac troponin T (cTnT) assay; the contemporary Gen 4 cTnT and high-sensitivity cardiac troponin I (hs-cTnI) assays were unaffected. The biotin interference threshold was 31, 315, and more than 2,000 ng/mL for Gen5 cTnT, cTnT, and hs-cTnI assays, respectively. Streptavidin pretreatment blocked biotin interference in cTn assays.

Conclusions
Biotin interference is possible at plasma concentrations achievable by ingestion of over-the-counter supplements that may lead to delayed or missed diagnosis of myocardial injury with the Gen5 cTnT assay.
Race, Representation, and Diversity in the American Association for Applied Linguistics
Authors: Bhattacharya Usree , Jiang Lei , Canagarajah Suresh 
Published: January 2019

AbstractSince its inception, the American Association for Applied Linguistics (AAAL) has advocated for diversity within the organization and in the discipline. This culminated in the passing of the resolution, ‘Affirming Commitment to Promoting Diversity’ (2013), hailing racial and other kinds of diversity as ‘an asset within our community and a source of learning and opportunity’. Despite this resolution, AAAL faces continuing challenges in realizing diversity in practice. This study turns the spotlight on the uneven professional mobility and visibility of scholars of color (SOCs) within AAAL, examining historical trends in the representation of SOCs in structures of power within AAAL as well as in recognition of meritorious scholarship. The data were mined from annual conference programs and official websites, and analyzed using computer software. Our analysis reveals stark disparity in the representation of SOCs across both metrics. We finally argue that cultivating greater racial diversity within AAAL is imperative for highlighting issues of race and inequality in applied linguistics; in expanding our epistemological field; and, ultimately, sustaining our vibrancy and strength as a discipline.
Visual Object Perception in Premanifest and Early Manifest Huntington’s Disease

Published: January 2019

Abstract

Objective
In Huntington’s disease (HD), a hereditary neurodegenerative disorder, cognitive impairment in early disease stages mainly involves executive dysfunction. However, visual cognitive deficits have additionally been reported and are of clinical relevance given their influence on daily life and overall cognitive performance. This study aimed to assess visual perceptual skills in HD gene carriers.

Methods
Subtasks of the Visual Object and Space Perception battery and Groningen Intelligence Test were administered in 62 participants (18 healthy controls, 22 participants with a genetic confirmation of HD without symptoms, i.e., premanifest HD, and 22 participants with a genetic confirmation of HD with symptoms, i.e., manifest HD). Group differences in task performance were measured using analysis of covariance with and without correction for age. Receiver Operating Characteristics (ROC) analysis was performed to examine which task best discriminated between groups and cut-off scores were provided.

Results
Manifest HD performed significantly worse compared to both controls and premanifest HD on all visual perceptional tasks. Premanifest HD did not differ in task performance from controls. Besides the Shape Detection, all tasks were robust in discriminating between groups. The Animal Silhouettes test was most accurate in discriminating manifest HD from premanifest HD (AUC = 0.90, SE = 0.048, p &lt; .001).

Conclusion
Visual perceptual deficits are present in early manifest HD, especially an impaired recognition of animals and objects from sketched silhouettes, and not in premanifest HD. This suggests that decline in visual processing only occurs in clinical disease stages. The visual cognitive battery, especially the Silhouettes tasks used in this study is sensitive in discriminating manifest HD from premanifest HD and controls.
General Educational Development (GED) and Educational Attainment Equivalency for Demographically Adjusted Norms†
Authors: Hewitt Kelsey C , Cody Meghan W , Marker Craig D , Loring David W 
Published: January 2019

Abstract

Objective
To investigate whether the General Educational Development (GED) certificate should be considered equivalent to a standard 12-year high school education when performing demographic corrections on neuropsychological performance levels. If the GED certificate and high school diploma reflect comparable levels of educational achievement, then performance on the Test of Premorbid Function (TOPF) and selected WAIS-IV indices should not differ between groups.

Method
Archival neuropsychology data were reviewed to identify patients who either (1) did not complete high school and did not subsequently obtain a GED, (2) did not complete high school but subsequently obtained a GED, or (3) completed high school and did not obtain any further formal education. Most patients were programmatic referrals for epilepsy surgery evaluation, although referrals from the general neurology clinic were also included. The primary dependent measures were the TOPF and WAIS-IV Full Scale IQ (FSIQ).

Results
High school graduates obtained higher scores on the TOPF (p &lt; .01, partial η2 = 0.16) and FSIQ (p &lt; .01, partial η2 = 0.14) as compared to both GED subjects and subjects withdrawing from high school with no GED. The non-GED group and the GED group did not differ from each other.

Conclusions
These findings demonstrate that the GED is not equivalent to a standard 12-year high school education when characterizing educational background. Although these data do not address what the appropriate year equivalent should be for the GED when adjusting performance for educational background, using 12 years will likely identify more areas of neuropsychological weakness simply by suggesting higher levels of premorbid ability.
Microdermal Grafting for Color Regeneration of White Scars
Authors: Tsao Su-Ben , Yang Pei-jung , Lin Tsan-Shiun 
Published: January 2019

Abstract
White scars are defined in this study as mature hypopigmented surgical or traumatic scars whose color is much lighter than surrounding skin, to the extent that they appear white. These scars are often obvious and very difficult to treat or mask. This 3-year retrospective study reports the outcomes from 38 recipients of a new microdermal grafting surgery we developed, which introduces melanocytes into the white scar lesion to regenerate skin color. The study shares 18 years of experience with this procedure, describes the surgical steps, offers videos of the procedures, and presents 4 cases. Between September 2013 and December 2016, 38 patients (30 females; 8 males) underwent microdermal grafting for color regeneration of white scars in our plastic surgery clinic. Most patients, 78.9%, received 1 treatment, 15.8% received 2 treatments, and 5.3% received 3 treatments. Three lay judges were asked to assess percentage pigmentation recovery by comparing photographic images of patients’ preoperative and postoperative scars. Patients were also asked to assess, via a questionnaire, satisfaction and percentage improvement 1 year after surgical treatment. Lay judges found an average of 49% improvement after 1 session, 75% after 2 sessions, and 90% after 3 sessions. In total, 71.1% of the patients completed the questionnaire 1 year after the surgery. Average subjective improvement was 55% after 1 session, 88% after 2 sessions, and 95% after 3 sessions. The patient satisfaction rate was high. Microdermal grafting provides adequate treatment of white scars by regenerating melanocytes, although more than 1 session treatment may be needed.
The Tissue-Based Triad in Augmentation Mastopexy: Single-Stage Technical Refinements
Authors: Sanniec Kyle , Adams William P 
Published: January 2019

Abstract

Background
The number of patients seeking augmentation mastopexy has increased over the last several decades. The conflicting goals of augmentation (tissue expansion) and mastopexy (tissue reduction) have led to higher revision rates, decreased patient satisfaction, and pending litigation. Some have even argued for staging of all augmentation mastopexy procedures.

Objectives
The goal of this study was to review the senior author’s (W.P.A.) process-oriented approach to single-stage augmentation mastopexy and to detail the technical framework to produce reliable, reproducible, safe results in a 1-stage augmentation mastopexy.

Methods
A prospectively collected patient database from January 2007 until January 2018 was reviewed. All single-stage augmentation mastopexy patients were evaluated, including patient demographics, operative details, complications, and outcomes.

Results
A total of 251 patients were evaluated. Mean follow-up was 16.9 months, average patient age was 38.0 years, and average implant size was 285.8 cc. A total of 9 (3.6%) patients required reoperation and only 2 (0.8%) required explantation. Fourteen (5.6%) patients developed delayed wound healing that responded to local wound care alone.

Conclusions
Utilization of a safe and reliable processed approach to single-stage augmentation mastopexy is highly predictable with low reoperation rates. The technical refinements presented have led to increased consistency in delivering high-quality results to patients in a procedure fraught with challenges.
