Published: March 2020

Abstract
Redox flow batteries (RFBs) are an emerging electrochemical technology suitable for energy-intensive grid storage, but further cost reductions are needed for broad deployment. Overcoming cell performance limitations through improvements in the design and engineering of constituent components represent a promising pathway to lower system costs. Of particular relevance, but limited in study, are the porous carbon electrodes whose surface composition and microstructure impact multiple aspects of cell behavior. Here, we systematically investigate woven carbon cloth electrodes based on identical carbon fibers but arranged into different weave patterns (plain, 8-harness satin, 2 × 2 basket) of different thicknesses to identify structure–function relations and generalizable descriptors. We first evaluate the physical properties of the electrodes using a suite of analytical methods to quantify structural characteristics, accessible surface area, and permeability. We then study the electrochemical performance in a diagnostic flow cell configuration to elucidate resistive losses through polarization and impedance analysis and to estimate mass transfer coefficients through limiting current measurements. Finally, we combine these findings to develop power law relations between relevant dimensional and dimensionless quantities and to calculate extensive mass transfer coefficients. These studies reveal nuanced relationships between the physical morphology of the electrode and its electrochemical and hydraulic performance and suggest that the plain weave pattern offers the best combination of these attributes. More generally, this study provides physical data and experimental insights that support the development of purpose-built electrodes using a woven materials platform.
Do Members of a Winning Soccer Team Engage in More Communication Than a Losing Team? A Single-Game Study of Two Competing Teams
Authors: McLaren Colin D. , Spink Kevin S. 
Published: March 2020

Emerging evidence suggests that team success is associated with communication among group members. This study built on those findings by examining the degree to which members on a winning (n = 13) and a losing (n = 13) men’s soccer team exchanged task-related information during a single head-to-head game. Social network analysis was used to compute athlete information exchange at the individual and team levels by asking players to identify the specific members with whom they exchanged information during the game. As hypothesized, athletes on the winning team had higher average individual degree centrality and higher network-density scores than athletes on the losing team. This indicates that individual members on the winning team exchanged task-related information with more of their teammates and, as a result, engaged in more collective information exchange as a team. While replication is necessary to increase generalizability, this study suggests a possible link between the degree that team members exchange information (at the individual and team level) and team performance outcome (i.e., win or loss).
Jump-Rope Training: Improved 3-km Time-Trial Performance in Endurance Runners via Enhanced Lower-Limb Reactivity and Foot-Arch Stiffness
Authors: García-Pinillos Felipe , Lago-Fuentes Carlos , Latorre-Román Pedro A. , Pantoja-Vallejo Antonio , Ramirez-Campillo Rodrigo 
Published: March 2020

Context: Plyometric training promotes a highly effective neuromuscular stimulus to improve running performance. Jumping rope (JR) involves mainly foot muscles and joints, due to the quick rebounds, and it might be considered a type of plyometric training for improving power and stiffness, some of the key factors for endurance-running performance. Purpose: To determine the effectiveness of JR during the warm-up routine of amateur endurance runners on jumping performance, reactivity, arch stiffness, and 3-km time-trial performance. Methods: Athletes were randomly assigned to an experimental (n = 51) or control (n = 45) group. Those from the control group were asked to maintain their training routines, while athletes from the experimental group had to modify their warm-up routines, including JR (2–4 sessions/wk, with a total time of 10–20 min/wk) for 10 weeks. Physical tests were performed before (pretest) and after (posttest) the intervention period and included jumping performance (countermovement-jump, squat-jump, and drop-jump tests), foot-arch stiffness, and 3-km time-trial performance. Reactive strength index (RSI) was calculated from a 30-cm drop jump. Results: The 2 × 2 analysis of variance showed significant pre–post differences in all dependent variables (P < .001) for the experimental group. No significant changes were reported in the control group (all P ≥ .05). Pearson correlation analysis revealed a significant relationship between Δ3-km time trial and ΔRSI (r = −.481; P < .001) and ΔStiffness (r = −.336; P < .01). The linear-regression analysis showed that Δ3-km time trial was associated with ΔRSI and ΔStiffness (R2 = .394; P < .001). Conclusions: Compared with a control warm-up routine prior to endurance-running training, 10 weeks (2–4 times/wk) of JR training, in place of 5 minutes of regular warm-up activities, was effective in improving 3-km time-trial performance, jumping ability, RSI, and arch stiffness in amateur endurance runners. Improvements in RSI and arch stiffness were associated with improvements in 3-km time-trial performance.
Estimating misclassification error in a binary performance indicator: case study of low value care in Australian hospitals
Authors: Badgery-Parker Tim , Pearson Sallie-Anne , Elshaug Adam G 
Published: March 2020

ObjectiveIndicators based on hospital administrative data have potential for misclassification error, especially if they rely on clinical detail that may not be well recorded in the data. We applied an approach using modified logistic regression models to assess the misclassification (false-positive and false-negative) rates of low-value care indicators.Design and settingWe applied indicators involving 19 procedures to an extract from the New South Wales Admitted Patient Data Collection (1 January 2012 to 30 June 2015) to label episodes as low value. We fit four models (no misclassification, false-positive only, false-negative only, both false-positive and false-negative) for each indicator to estimate misclassification rates and used the posterior probabilities of the models to assess which model fit best.ResultsFalse-positive rates were low for most indicators—if the indicator labels care as low value, the care is most likely truly low value according to the relevant recommendation. False-negative rates were much higher but were poorly estimated (wide credible intervals). For most indicators, the models allowing no misclassification or allowing false-negatives but no false-positives had the highest posterior probability. The overall low-value care rate from the indicators was 12%. After adjusting for the estimated misclassification rates from the highest probability models, this increased to 35%.ConclusionBinary performance indicators have a potential for misclassification error, especially if they depend on clinical information extracted from administrative data. Indicators should be validated by chart review, but this is resource-intensive and costly. The modelling approach presented here can be used as an initial validation step to identify and revise indicators that may have issues before continuing to a full chart review validation.

Published: March 2020

ObjectiveDirect inhibition of acetylcholine receptor (AChR) function by autoantibodies (Abs) is considered a rare pathogenic mechanism in myasthenia gravis (MG), but is usually studied on AChRs expressed in cell lines, rather than tightly clustered by the intracellular scaffolding protein, rapsyn, as at the intact neuromuscular junction. We hypothesised that clustered AChRs would provide a better target for investigating the functional effects of AChR-Abs.MethodsAcetylcholine-induced currents were measured using whole-cell patch clamping and a fast perfusion system to assess fast (<2 min) functional effects of the serum samples. The sensitivity, specificity and rapidity of the system were first demonstrated by applying maternal AChR-Ab positive plasmas known to inhibit fetal AChR function in TE671 cells. Eleven previously untested AChR-Ab positive MG sera, 10 AChR-Ab negative MG sera and 5 healthy control sera were then applied to unclustered and rapsyn-clustered human adult AChRs in CN21 cells.ResultsThe maternal AChR-Ab positive plasmas reduced fetal AChR currents, but not adult AChR currents, by >80% within 100 s. Only 2/11 AChR-Ab positive sera inhibited AChR currents in unclustered AChRs, but 6/11 AChR-Ab positive sera compared with none of the 10 AChR-Ab negative sera (p=0.0020) inhibited rapsyn-clustered AChR currents, and current inhibition by the AChR-Ab positive sera was greater when the AChRs were clustered (p=0.0385). None of the sera had detectable effects on desensitisation or recovery from desensitisation.ConclusionThese results show that antibodies can inhibit AChR function rapidly and demonstrate the importance of clustering in exploring pathogenic disease mechanisms of MG Abs.
Comparison of the effectiveness of circumferential versus non-circumferential spread in median and ulnar nerve blocks. A double-blind randomized clinical trial

Published: March 2020

Background and objectivesCircumferential (C) spread of local anesthetic around the nerve is recommended for a successful nerve block. We tested the hypothesis that C spread produces a more complete block than non-circumferential (NC) spread.MethodsWe randomized 124 patients undergoing open carpal tunnel syndrome surgery to receive C or NC spread ultrasound-guided median and ulnar nerve blocks. The primary outcome was the proportion of patients who developed complete sensory block measured at 5, 15 and 30 min. The loss of cold sensation was graded as: 0 (complete block), 1 (incomplete block), or 2 (no block). Secondary outcomes included motor block, nerve swelling and adverse events.ResultsIn group C, complete sensory block at 5 min was 2.4 (95% CI 1.0 to 5.7; p=0.04) times more frequent in the median nerve and 3.0 (95% CI 1.2 to 7.2; p=0.01) times more frequent in the ulnar nerve compared with group C. However, at 15 and 30 min, it was similar between groups. Complete motor block was more frequent in group C than in group NC for both the median nerve: 1.5 (95% CI 1.1 to 2.2; p<0.01) at 15 min, 1.1 (95% CI 1.0 to 1.2; p=0.02) at 30 min, and the ulnar nerve: 1.7 (95% CI 1.2 to 2.6; p<0.01) at 15 min, 1.2 (95% CI 1.0 to 1.4; p<0.01) at 30 min. The incidence of nerve swelling and adverse effects was similar between groups.ConclusionsC spread around the median and ulnar nerves at the level of the antecubital fossa generates more complete sensory and motor blocks compared with NC spread.Trial registration numberEudraCT 2011-002608-34 andNCT01603680
New constraints on heavy neutral leptons from Super-Kamiokande data
Authors: Coloma P. , Hernández P. , Muñoz V. , Shoemaker I. M. 
Published: March 2020

AbstractHeavy neutral leptons are predicted in many extensions of the Standard Model with massive neutrinos. If kinematically accessible, they can be copiously produced from kaon and pion decays in atmospheric showers, and subsequently decay inside large neutrino detectors. We perform a search for these long-lived particles using Super-Kamiokande multi-GeV neutrino data and derive stringent limits on the mixing with electron, muon and tau neutrinos as a function of the long-lived particle mass. We also present the limits on the branching ratio versus lifetime plane, which are helpful in determining the constraints in non-minimal models where the heavy neutral leptons have new interactions with the Standard Model.
Oocyte Vitrification: A Comparative Analysis Between Fresh and Cryopreserved Oocytes in an Oocyte Donation Program
Authors: Talreja Deepa , Gupta Chirag , Pai Hrishikesh , Palshetkar Nandita 
Published: March 2020

Background: Oocyte Cryopreservation has become an important part of infertility treatment for various reasons such as fertility preservation in women going for oncological treatment; in oocyte donation cycles; in eliminating several religious, ethical, and legal concerns of embryo freezing and in women who wish to delay childbirth. The newer ”vitrification” technique for freezing has further improved the success rates for actual conception than the earlier method of slow freezing. A successful oocyte freezing program can help in establishment of oocyte banks, which would help to provide compatible oocytes immediately, thus would eliminate the several problems of fresh donor cycles. Methods: In this retrospective observational study, total 60 oocyte donation cycles were included (38 were fresh and 22 were vitrified oocytes cycle, respectively). After a thorough screening, controlled ovarian hyperstimulation for donors was performed using flexible antagonist protocol. All mature oocytes were allocated into “vitrified oocytes” and “fresh oocytes” groups. Vitrification technique using Cryotop method was used for oocyte freezing. Both clinical and laboratory outcomes of vitrified and fresh oocytes in donor cycles were compared. Results: A total of 600 oocytes (226 “vitrified oocytes” and 374 fresh oocytes), were studied. After warming 218 oocytes survived resulting in survival rate of 96.4%. Fertilization rate and embryo formation rate was 86.2% and 93.6%, respectively. Results of frozen-thawed oocyte donor cycles were compared with fresh donation cycles. For fresh oocyte group, fertilization rate and embryo formation rate was 83.4% and 92.6%, respectively. On comparing clinical outcomes, clinical pregnancy rate was 60.5% in fresh group and 63.6% in vitrified group. Conclusions: Both clinical and laboratory results obtained in the study suggest that oocyte cryopreservation can be performed with reproducible success, thus vitrification technique can be provided as a useful tool for achieving highly successful outcomes in an oocyte donor program.
‘BAKWATA is Like a Dead Spirit to Oppress Muslims’
Authors: Wijsen Frans , Mosha Peter Tumainimungu 
Published: March 2020

Abstract
During the 2015 general election campaigns in Tanzania, a controversy arose between the ruling party and the opposition coalition, concerning the proposed constitution draft and the position of Zanzibar within the Union. Beyond this controversy, there have existed the impacts of Islamic revivalism on the one hand, and a fear for the perpetuation of Islam in Tanzania on the other – issues which have played a significant role in the country since Independence. In this paper, we focus in particular upon popular Muslim preachers, such as Ponda Issa Ponda, who complain that the National Muslim Council of Tanzania [BAKWATA] is just an extension of the mainstream government – an organisation which is unsympathetic to Muslims’ interests, which violates Muslims’ rights, and which functions contrary to its own purpose. This complaint draws on long-term memory, reaching back even further than the 1968 banning of the East African Muslims Welfare Society [EAMWS]. Two interesting questions are addressed here concerning a central state’s involvement in religious affairs under multi-party rule: How has the Tanzanian government managed religious diversity? And how should its management style be evaluated, given the perspective that has developed with the shift in focus from ‘government’ to ‘governance’ in policy and management sciences?
Graduated Sovereignty and Tanzania’s Mineral Sector
Authors: Noe Christine 
Published: March 2020

Abstract
The process through which state sovereignty over natural resources is gained and lost serves as a precondition for other external actors to acquire rights and to appropriate wealth. These external institutions are multinational firms and non-governmental organizations that do not rely on sovereign entities. By building on the concept of graduated sovereignty, the example of Tanzania’s mineral resource demonstrates how ownership rights shift, creating different impacts on the ground. Analysis of historical and contemporary changes in Tanzania’s mineral laws serves as a basis for revealing the ways in which sovereignty is differentiated or graduated within a national territory, given current global relations. Since neither global resource governance nor market conditions are static or predictable, the government of Tanzania responds differently to external forces over time. Tanzania’s most recent national decisions follow the model of neoliberal flexibility and maximisation of profit from natural resources. Consequently, more complex issues of local resource rights have remained unattended over the years of policy and legal reform, resulting in discriminatory treatment and marginalization of different groups in Tanzanian society.
The Incorporation of the Kiswahili Names of Cereals and Tubers in the Non-Bantu Languages in Tanzania
Authors: Lusekelo Amani 
Published: March 2020

Abstract
I articulate the mechanisms for the incorporation of Kiswahili names of the New World cereals and tubers in the Afro-asiatic, Khoisan and Nilo-Saharan languages spoken in Tanzania. The penetration of pastoral-terms from non-Bantu societies into Bantu communities is extensively documented. But research on the impact of Kiswahili on non-Bantu languages has not been given prominence except in a few studies. Thus, specific investigation of the names of cereals and tubers into non-Bantu languages is incomplete. With regard to transference of the nomenclature of the farm-related products, I show that the major donor languages in this study include Iraqw and Kiswahili. This result illuminates the fact that agro-pastoral communities (e.g. Iraqw) influence the lexicon of languages spoken by pastoralists (e.g. Datooga) and foraging communities (e.g. Hadza). I show that Kiswahili is the main agent of names of agriculture in non-Bantu communities. Moreover, I highlight that the names of crops are integrated through assignment of gender-number markers primarily in Hadza, Iraqw and Maasai. In Datooga, I show that the number suffixes dominate as the strategy to incorporate Kiswahili words in the language.

Published: March 2020

Objective: To investigate the prevalence and risk factors associated with chronic pain and other symptoms related to breast cancer 6 months after surgery. Methods: In an observational study of 261 female breast cancer survivors treated between January 2017 and January 2018, patients were asked about their pain symptoms using a questionnaire that utilized the Numeric Rating Score (NRS) and the Douleur Neuropathique Score (DN4) for neuropathic pain; it also addressed phantom sensations and functional disorders on the ipsilateral shoulder. A total of 218 women completed the survey. Results: A total of 105 patients (48.17%) reported chronic pain. Of these, 64% rated the pain with an NRS of 1–3 and 35% with an NRS >3. Neuropathic pain was reported in 65% of the sample, phantom sensations in 12%, disorders of shoulder function in 16%, and web syndrome in 2%. Multivariable analyses showed that chronic pain (odds ratio [OR], 2.55; 95% confidence interval [CI], 1.094–5.942; p < 0.05) and neuropathic pain (OR, 2.988; 95% CI, 1.366–6.537; p < 0.05) were positively associated with surgical adverse events; phantom sensations were statistically associated with the weight of removed breast tissue (OR, 1.003; 95% CI, 1.001–1.005; p < 0.05). Conclusions: Our study highlights the need to employ specific tools capable of detecting different kinds of chronic pain after breast cancer surgery to improve pain prevention and treatment. Surgical complications and the weight of removed breast tissue emerged as 2 of the risk factors for chronic and neuropathic pain development in breast cancer survivors.

Published: March 2020

Objectives This work presents an ambient-assisted living application that encourages seniors during nocturnal wandering episodes to return to bed in calm and comfort reassurance. Methods Structuring knowledge by designing a software architecture capable of delivering high-level analysis and processing. A senior’s home has been upgraded into a smart home enabling the gathering of habits for two weeks and set up for personalized assistance over four weeks. Home automation devices associated with Actigraph monitors and self-reported sleep were used for more accuracy. Results The architectural model can be used in ambient-assisted living applications for which data collection is permanent and continuous. Its layered organization facilitates the management of specific and general activities of daily life. The results of the home experience show that the system gave a notification whenever the need arose. On the other hand, it allowed the caregiver to get more information about the lifestyle of the senior. Conclusions Future work should focus on providing more services to contextualize assistance. Ontology is used to structure all the ambient knowledge of the smart home. We also plan to do more home experiments.

Abstract
Background
Despite the high prevalence of fetal alcohol spectrum disorder (FASD), there are few interventions targeting its core neurocognitive and behavioral deficits. FASD is often conceptualized as static and permanent, but interventions that capitalize on brain plasticity and critical developmental windows are emerging. We present a long-term follow-up study evaluating the neurodevelopmental effects of choline supplementation in children with FASD 4 years after an initial efficacy trial.

Methods
The initial study was a randomized, double-blind, placebo-controlled trial of choline vs. placebo in 2–5-year-olds with FASD. Participants include 31 children (16 placebo; 15 choline) seen 4 years after trial completion. The mean age at follow-up was 8.6 years. Diagnoses were 12.9% fetal alcohol syndrome (FAS), 41.9% partial FAS, and 45.1% alcohol-related neurodevelopmental disorder. The follow-up included measures of intelligence, memory, executive functioning, and behavior.

Results
Children who received choline had higher non-verbal intelligence, higher visual-spatial skill, higher working memory ability, better verbal memory, and fewer behavioral symptoms of attention deficit hyperactivity disorder than the placebo group. No differences were seen for verbal intelligence, visual memory, or other executive functions.

Conclusions
These data support choline as a potential neurodevelopmental intervention for FASD and highlight the need for long-term follow-up to capture treatment effects on neurodevelopmental trajectories.
