The value of the scholarly-led, non-profit business model to achieve Open Access and scholarly publishing beyond APC
Authors: Becerril-García Arianna 
Published: September 2019

Keynote presentation.
The prevailing science communication system has showed little success in making science a global, participatory and equitable conversation. At the same time, a very robust ecosystem of science communication has been built in the Latin-American region, one that is intrinsically open, non-commercial and academy-owned. However, this “regional” approach has remained outside the legitimated channels of scholarly communication.
In Latin America, more than 2000 universities are publishing journals under the principle of science as a common and public good. Around half of them are public institutions which means that public budget is being heavily invested in sustaining non-commercial Open Access.
AmeliCA, a multi-institutional community-driven initiative supported by UNESCO and led by Redalyc and CLACSO, seeks a cooperative, sustainable, protected and non-commercial solution for Open Knowledge. AmeliCA is taking the 16-year experience and technological resources from Redalyc to strengthen non-profit publishing beyond the region.
AmeliCA’s and Redalyc’s approach is based on the fact that scholarly communication in control of the academy is a strategy much healthier and sustainable for the development of science and society. Why is it that commercial publishers are a pivotal actor in science communication – in many parts of the world – if the biggest part of activities concerning the generation of knowledge is in the academy?
Academy owned publishing seems not to exist in the mainstream databases (Web of Science and Scopus). So, it is strategic for the research community and libraries to join forces, as well as share and connect individual efforts to build a cooperative infrastructure, in order to guarantee that publishing is led by the scholarly community and that its openness is sustainable. The research community and libraries should also work together in the reshaping of how research is assessed, in order to give the non-profit academy-owned scholarly communications their place. All must be leveraged with technology to find more effective methods of communication and deployment of the knowledge generated by different regions, disciplinary fields or languages.
The State of Proteins not with Standing, Translational Velocity is Vital for their Function
Authors: Udema Ikechukwu Iloh , Onigbinde Abraham Olalere 
Published: September 2019

Background: Targeting of macromolecules by means of translational diffusion for therapeutic reason is generally of interest. But translational velocity that enables directional delivery of any molecule on target is given less attention.
Objectives: The objectives of this research are to: 1) determine the value of the cohesion factor affecting solutes, 2) determine the translational velocity of porcine pancreatic (PPAA) - and human salivary (HSAA) – alpha amylase and ions, 3) rederive the effective kinetic energy (K.E.) of solutes, 4) determine the thermodynamic parameters for a folded to an unfolded transition and 5) give reasons why the velocity of solution components is generally very important.
Methods: A theoretical research and experimentation using Bernfeld method.
Results and Discussion: The K.E. of solution components as re-derived is « 3kBT / 2 (where kB and T are Boltzmann constant and Kelvin temperature respectively.). The velocities of hydrolysis of the substrate with the sucrose-treated PPAA were generally higher than those of HSAA. The values of conformational entropy change (∆Sconf) for PPAA were generally higher than those of HSAA. Expectedly the values of ∆Sconf were positive.
Conclusion: In conclusion, the square root of the cohesion factor is larger than 22.4 exp (+3) 310.15 K / 273.15 K / 18, accounting for the translational velocity (u) in solution being « gas phase velocity (U). The translational diffusion D and u remain respectively, a function of the hydrodynamic radius of the solutes in particular and the magnitude of D; unfolding of proteins decreases the values of the parameters. Overall, unfolding is entropy driven. Without the mobility of solution components at desired velocity directional delivery of small molecules to site of need such as intrinsically disordered proteins etc may remain impossible.

Published: September 2019

AbstractDeveloping electrochemical energy storage devices with high energy–power densities, long cycling life, as well as low cost is of great significance. Sodium‐ion capacitors (NICs), with Na+ as carriers, are composed of a high capacity battery‐type electrode and a high rate capacitive electrode. However, unlike their lithium‐ion analogues, the research on NICs is still in its infancy. Rational material designs still need to be developed to meet the increasing requirements for NICs with superior energy–power performance and low cost. In the past few years, various materials have been explored to develop NICs with the merits of superior electrochemical performance, low cost, good stability, and environmental friendliness. Here, the material design strategies for sodium‐ion capacitors are summarized, with focus on cathode materials, anode materials, and electrolytes. The challenges and opportunities ahead for the future research on materials for NICs are also proposed.
Bands of E-Inversive Unipotent Semigroups
Authors: Gigoń Roman S. 
Published: September 2019

AbstractWe study some special types of bands ofE-inversive unipotent semigroups. It has been proved that in anyR-semigroupS, which is a band ofE-inversive unipotent semigroups, the set of its regular elements is a retract ofS. Also, some characterizations ofE-inversive rectangular bands of unipotent semigroups are given. This theorem extends nearly 40-old results from the theory of epigroups. In fact, a more general result is valid in some special subclass of the class ofE-inversive semigroups; this result seems to be (partially) new for all epigroups.

Published: September 2019

AbstractIntroductionQuestions remain about whether apolipoprotein E (APOE)‐ε4 effects on cognitive decline are similar in men and women and how APOE‐ε4 and age interact to influence decline in different cognitive domains.MethodsIn sex‐stratified analyses, baseline age‐dependent associations between APOE‐ε4 status and longitudinal cognitive trajectories were examined in cognitively normal Caucasian older adults (631 men, 561 women, baseline age range: 50–93, 6733 assessments).ResultsIn men, older baseline age was associated with greater effects of APOE‐ε4 on longitudinal decline in memory and executive function, detectible from baseline age of 64 and 68, respectively. In women, older baseline age was associated with greater APOE‐ε4 effects on longitudinal decline in attention, detectible at baseline age of 66. No significant APOE‐ε4 effects were found for language, visual‐spatial ability, or processing speed.DiscussionResults highlight the importance of considering sex and age when assessing APOE‐ε4–associated vulnerability to cognitive decline.
Meter, prosody and performance: evidence from the Faroese ballads
Authors: Galbraith Daniel 
Published: September 2019

AbstractIn this paper, I argue that the folk ballad tradition of the Faroe Islands, to date never examined in detail by metrists, offers substantial empirical support for the necessity of maintaining the classic metrical template, as well as the distinction between metrical and prosodic structure: meter is an abstraction which can neither be collapsed into phonology, nor fundamentally detached from it (Kiparsky 2006, Blumenfeld 2015,paceHayes & MacEachern 1998, Fabb & Halle 2008). The ballad performances also reveal a unidirectional correspondence from strong metrical positions to strong dance steps and strong musical beats, indicating that metrical prominence plays a significant role in determining rhythm. The Faroese tradition thus provides a window into the relation between metrical structure and performance. In support of my conclusions I draw upon both the ballad texts and audio-visual recordings of sections of sample ballads I made on the Faroe Islands.

Published: September 2019

AbstractBiofilm-dispersal is a key determinant for further dissemination of biofilm-embedded bacteria. Recent evidence indicates that biofilm-dispersed bacteria have transcriptional features different from those of both biofilm and planktonic bacteria. In this study, the in vitro and in vivo phenotypic properties of Klebsiella pneumoniae cells spontaneously dispersed from biofilm were compared with those of planktonic and sessile cells. Biofilm-dispersed cells, whose growth rate was the same as that of exponential planktonic bacteria but significantly higher than those of sessile and stationary planktonic forms, colonized both abiotic and biotic surfaces more efficiently than their planktonic counterparts regardless of their initial adhesion capabilities. Microscopy studies suggested that dispersed bacteria initiate formation of microcolonies more rapidly than planktonic bacteria. In addition, dispersed cells have both a higher engulfment rate and better survival/multiplication inside macrophages than planktonic cells and sessile cells. In an in vivo murine pneumonia model, the bacterial load in mice lungs infected with biofilm-dispersed bacteria was similar at 6, 24 and 48 h after infection to that of mice lungs infected with planktonic or sessile bacteria. However, biofilm-dispersed and sessile bacteria trend to elicit innate immune response in lungs to a lesser extent than planktonic bacteria. Collectively, the findings from this study suggest that the greater ability of K. pneumoniae biofilm-dispersed cells to efficiently achieve surface colonization and to subvert the host immune response confers them substantial advantages in the first steps of the infection process over planktonic bacteria.
Hydrostatic equilibrium preservation in MHD numerical simulation with stratified atmospheres
Authors: Krause G. 
Published: September 2019

Context. Many astrophysical processes involving plasma flows are produced in the context of a gravitationally stratified atmosphere in hydrostatic equilibrium, in which strong gradients can exist with gas properties that vary in small regions by several orders of magnitude. The standard Godunov-type schemes with polynomial reconstruction used to numerically solve these problems fail to preserve the hydrostatic equilibrium owing to the appearance of spurious fluxes generated by the numerical unbalance between gravitational forces and pressure gradients.
Aims. The aim of this work is to present local hydrostatic reconstruction techniques that can be implemented in existing codes with Godunov-type methods to obtain well-balanced schemes that numerically satisfy the hydrostatic equilibrium for various conditions.
Methods. The proposed numerical scheme is based on the Godunov method with second order MUSCL-type reconstruction, as is extensively used in astrophysical applications. The difference between the scheme and the standard formulations is only given by calculating the pressure and density Riemann states on each intercell face and by computing the gravitational source term on each cell.
Results. The local hydrostatic reconstruction scheme is implemented in the FLASH code to verify the well-balanced property for hydrostatic equilibrium with constant or linearly variable temperature and constant or variable gravity. In addition, the behavior of the scheme for hydrostatic equilibrium with arbitrary temperature distributions is also analyzed together with the ability to propagate low-amplitude waves and to capture shock waves.
Conclusions. The scheme is demonstrated to be robust and relatively simple to implement in existing codes. This approach produces good results in hydrostatic equilibrium preservation, satisfying the well-balanced property for the preset conditions and strongly reducing the spurious fluxes for extreme configurations.

Objective This study aimed to provide the correlation of circadian rhythms of night shift workers with blood glucose levels, saliva, and dental caries.
Materials and Methods This study was conducted on night shift and nonshift workers to measure fasting blood glucose (FBG), 2-hour postprandial blood glucose (2-PP BG), saliva flow rate, pH saliva, and caries with the decay-missing-filled total (DMF-T) index. Data analysis was done using independent t-test and correlation test with Pearson correlation.
Results There were significant differences in night shift and nonshift workers in FBG (p = 0.000), 2-PP BG (p = 0.000), flow rate saliva (p = 0.000), and DMF-T index (p = 0.001). Correlation test showed positive correlation between FBG and pH saliva (r = 0.42, p = 0.029) and DMF-T index (r = 0.521, p = 0.005) of night shift workers. The 2-PP BG also showed positive correlation with pH saliva (r = 0.493, p = 0.009) and DMF-T index (r = 0.743, p = 0.000). The DMF-T index showed negative correlation with flow rate saliva (r = –0.398, p = 0.04). In the nonshift workers, correlation test showed a correlation between FBG and DMF-T index (r = 0.384, p = 0.048). The DMF-T index showed correlation with flow rate saliva (r = 0.6, p = 0.001).
Conclusion There is a circadian rhythm correlation between night shift workers to blood glucose levels, flow rate saliva, pH saliva, and dental caries.

Published: September 2019

Abstract
Introduction Antiepileptic drug (AED) therapy has been used prophylactically in various centers in patients with chronic subdural hematoma (CSDH) after surgical evacuation, although the benefit is unclear.
Materials and Methods In this randomized controlled trial, patients with CSDH undergoing burr hole drainage were enrolled into two groups—one which received prophylactic phenytoin and the other without the drug use. Their clinical presentation, imaging findings and postoperative complications were analyzed. Primary objective of the study was to assess the efficacy of phenytoin in the reduction of early postoperative seizure.
Results A total of 54 patients were enrolled in the study and randomized into two groups. Twenty-seven patients were assigned into the phenytoin group while another 27 patients to the “no phenytoin” group. Analysis of all patients in the no phenytoin group and those in the phenytoin group with therapeutic serum phenytoin levels were done. The incidence of postoperative seizure was 5.7%; and all patients who had seizures were in the no phenytoin group. This, however, was not statistically significant (p = 0.262). Two out of 25 patients on phenytoin (8%) developed adverse drug reactions.
Conclusion Incidence of postoperative seizure in patients undergoing burr hole drainage for CSDH was low. Routine prophylactic use of AED, did not reduce seizure in early postoperative period.
The development of verb constructions in spoken learner English
Authors: Römer Ute , Garner Jamie 
Published: September 2019

AbstractBased on datasets of L1 Italian and Spanish learner language culled from the Trinity Lancaster Corpus Sample, this paper investigates how verb-argument constructions (VACs) develop in the spoken English of L2 learners across proficiency levels. In addition to proficiency and L1 effects, we focus on the potential influence of native English usage on learner VAC production. Insights into learners’ productive knowledge of five target VACs and the verbs used in those VACs are gained through (1) comparisons of normalized entropy scores for verbs in VACs; (2) correlation analyses comparing for each VAC the verbs produced by groups of learners and by native English speakers; and (3) regression analyses comparing learner verb-VAC associations against indices of VAC usage, including verb-VAC frequency, VAC-verb association strength and contingency. Results indicate that, across L1 backgrounds, more proficient learners are more productive in their VAC use and closer to patterns in L1 English usage than less proficient learners.

Abstract

Background
Maternal human immunodeficiency virus (HIV) infection is associated with lower placental transfer of antibodies specific to several childhood pathogens. Our objective for this study was to evaluate the effect of maternal HIV infection on the placental transfer of respiratory syncytial virus (RSV)-neutralizing antibodies.

Methods
We conducted a cross-sectional study of mothers and their newborn infants at a tertiary hospital in Gaborone, Botswana, between March 2015 and December 2015. We measured serum RSV antibody levels by using a microneutralization assay. We used multivariable linear regression to evaluate the effect of maternal HIV infection on maternal RSV antibody levels, placental transfer of RSV antibodies, and newborn RSV antibody levels.

Results
Of 316 mothers, 154 (49%) were infected with HIV. The placental transfer ratios for RSV antibodies to HIV-exposed, uninfected (HEU) and HIV-unexposed, uninfected infants were 1.02 and 1.15, respectively. The geometric mean titer (95% confidence interval) of RSV-neutralizing antibodies was 2657 (2251–3136) among HEU newborns and 2911 (2543–3331) among HIV-unexposed, uninfected newborns. In multivariable analyses, maternal HIV infection was associated with lower placental transfer of RSV antibodies (P = .02) and a lower level of RSV antibodies among newborns (P = .002). Among HEU newborns, higher birth weight (P = .004) and an undetectable maternal antenatal viral load (P = .01) were associated with more effective placental transfer of RSV antibodies.

Conclusions
Maternal human immunodeficiency virus (HIV) infection is associated with lower mother-to-fetus transfer of serum RSV-neutralizing antibodies. HEU infants should be prioritized for preventive interventions for RSV. Maternal viral suppression through combination antiretroviral therapy has the potential to improve immunity to RSV among HIV-exposed infants.

Abstract

Background
The impact of immunosuppression on outcomes in influenza is insufficiently understood. We analyzed the morbidity and mortality of immunocompetent (IC) vs immunosuppressed (IS) patients with influenza A and B in the 2017/2018 season.

Methods
Patients with proven influenza in a German tertiary care hospital were analyzed for hospitalization, intensive care unit (ICU) admission, and mortality. Causes for IS were organ and bone marrow transplantation, AIDS, chemotherapy, and medical immunosuppression.

Results
In total, 227 patients were included in this analysis (IC, n = 118 [52%]; IS, n = 109 [48%]). Hospitalization (71% vs 91%; P &lt; .001) and ICU admission (7% vs 23%; P = .001) were less frequent in the IS compared with the IC group. IC patients had a higher need for invasive ventilation (20% vs 5%; P = .001), vasopressors (19% vs 4%; P &lt; .001), and renal replacement therapy (15% vs 3%; P = .002). Influenza-associated cardiomyopathy was found in 18% of IC vs 2% of IS patients (P &lt; .001). The 30-day in-hospital mortality was 6.6%, 10.2% in the IC group and 2.8% in the IS group (hazard ratio IS group, 0.259; 95% confidence interval [CI], 0.113–0.855; P = .023). Immunosuppression was associated with reduced mortality (odds ratio, 0.25; 95% CI, 0.07–0.91; P = .036).

Conclusions
We observed that IS was not associated with a worse outcome in this influenza cohort. Due to the presence of both confounding and referral and selection bias, the conclusion that immunosuppression reduces mortality cannot be drawn. Prospective studies investigating the influence of baseline immunosuppression on severity of influenza infection are desirable.

Published: September 2019

Purpose:
To evaluate the effect of plantar flexor strengthening associated with conventional physical therapy treatment in participants with idiopathic toe walking.

Methods:
Thirty participants, of both sexes diagnosed with idiopathic toe walking, aged 5 and 11 years, will be recruited and randomized into 2 groups: the control group, who will undergo gait training, triceps surae muscle stretching, anterior tibial muscle strengthening, and motor sensory training, and the intervention group, who will undergo the same training as the control group and, additionally, triceps surae muscle strengthening. The intervention will be performed twice a week for 8 weeks. The participants will undergo a 3-dimensional gait kinematic analysis, passive amplitude of dorsiflexion movement, isometric dynamometry of the anterior tibial and triceps surae muscles, motor coordination, quality of life, and perception of the parents regarding the equinus gait at baseline and at the end of treatment. Quality of life will be reevaluated during a 24-week follow-up.
