ABSTRACTPurposeFew studies have investigated recovery between sexes using objective outcome measures. Our purpose was to examine the independent association between biological sex and recovery of postconcussion gait among collegiate athletes.MethodsWe evaluated participants with a diagnosed concussion <7 d postinjury, and approximately 1.5 months and 3.5 months postinjury. Participants completed a single/dual-task gait evaluation and symptom inventory. During dual-task trials, they completed a mental task (backward subtraction, spelling, or month recitation). The primary outcome measure was height-adjusted gait velocity recovery, defined as achieving normal gait velocity using established values: >0.56 and >0.50 gait velocity (m·s−1)/height (m) under single and dual-task conditions, respectively. We used a multivariable Cox proportional hazard model to identify associations between sex and dual-task recovery, controlling for age, concussion history, symptom severity, and loss of consciousness at the time of injury.ResultsNinety-four individuals participated in the study: 47 (50%) were female athletes (mean age = 20.1, SD = 1.3 yr) and 47 (50%) were male athletes (mean age = 20.3, SD = 1.3 yr). Sex was not independently associated with height-adjusted single-task gait velocity recovery after controlling for potential confounders (hazard ratio = 1.62, 95% confidence interval = 0.87–3.01). However, male sex was independently associated with longer dual-task gait recovery time after controlling for potential confounders (hazard ratio = 2.43, 95% confidence interval = 1.11–5.35).ConclusionMale athletes required a longer duration of time after concussion to achieve dual-task gait recovery than female athletes. Thus, functional dual-task abilities after concussion may be affected differentially by sex and should be accounted for within individualized concussion management strategies.

ABSTRACT
The degree to which standard laboratory gait assessments accurately reflect impact loading in an outdoor running environment is currently unknown.

Purpose
To compare tibial shock between treadmill and road marathon conditions.

Methods
One hundred ninety-two runners (men/women, 105/87; age, 44.9 ± 10.8 yr) completed a treadmill gait assessment while wearing a tibial-mounted inertial measurement unit, several days before completing a marathon race. Participants ran at 90% of their projected race speed and 30 s of tibial shock data were collected. Participants then wore the sensors during the race and tibial shock was averaged over the 12th, 23rd, and 40th kilometers. One-way analysis of covariance and correlation coefficients were used to compare vertical/resultant tibial shock between treadmill and marathon conditions. Analyses were adjusted for differences in running speed between conditions.

Results
A significant main effect of condition was found for mean vertical and resultant tibial shock (P < 0.001). Early in the marathon (12-km point), runners demonstrated higher mean tibial shock adjusted for speed compared with the treadmill data (vertical = +24.3% and resultant = +30.3%). Mean differences decreased across the course of the marathon. Vertical tibial shock at the 40th kilometer of the race was similar to treadmill data, and resultant shock remained higher. Vertical and resultant tibial shock were significantly correlated between treadmill and the 12th kilometer of the race (r
s = 0.64–0.65, P < 0.001), with only 40% to 42% of the variance in outdoor tibial shock explained by treadmill measures. Correlations for tibial shock showed minimal changes across stages of the marathon.

Conclusions
These results demonstrate that measures of impact loading in an outdoor running environment are not fully captured on a treadmill.

Published: January 2020

In this paper, an ultra-wideband terahertz absorber is designed utilizing a graphene-based metasurface. The absorber is composed of three layers including the graphene metasurface, Topas-cyclic olefin copolymer dielectric substrate, and a gold ground layer. The particle swarm optimization algorithm and interpolate quasi-Newton optimization are utilized to find an optimized structure with the widest bandwidth. Full-wave simulations verify achieving absorbance of more than 90% in an extremely wide frequency band within the range of 1 THz to 3.5 THz (fractional bandwidth = 111%) under illumination of a normal incident wave. The proposed structure is polarization insensitive up to a polarization angle of 75°, while the performance of the absorber (absorbance level and bandwidth) is almost fixed for incident angles

up to 60°. Moreover, the switching capability of the structure from reflection (

Published: January 2020

Silicon nitride (Si3N4) waveguides offer low-loss wave propagation over a wide spectral range including visible wavelengths and lend themselves to photonic integrated circuits for bio-photonic applications. The Si3N4 device portfolio, however, is so far limited to passive devices that need to be fed by external light sources. This often requires delicate and costly fiber-chip coupling schemes that are subject to stringent alignment tolerances. In this paper, we present and investigate a class of lasers that combine Si3N4 waveguides with light-emitting organic cladding materials in a hybrid approach. These Si3N4-organic hybrid (SiNOH) lasers are operated by optical pumping from the top with low alignment precision. We theoretically and experimentally investigate different SiNOH laser concepts based on spiral-shaped ring resonators and distributed feedback (DFB) resonators. While our devices are designed for an emission wavelength of approximately 600 nm, the SiNOH laser concept can be transferred to a large range of wavelengths in the visible spectrum. The devices are amenable to cost-efficient mass production and have the potential to address a wide range of applications in bio-photonics and point-of-care diagnostics.

Published: January 2020

At the level of peak powers needed for a Kerr-lens mode-locked operation of solid-state soliton short-pulse lasers, a periodic perturbation induced by spatially localized pulse amplification in a laser cavity can induce soliton instability with respect to resonant dispersive-wave radiation, eventually leading to soliton blowup and pulse splitting of the laser output. Here, we present an experimental study of a high-peak-power self-mode-locking Cr:forsterite laser, showing that, despite its complex, explosion-like buildup dynamics, this soliton blowup can be captured and quantitatively characterized via an accurate cavity-dispersion- and gain-resolved analysis of the laser output. We demonstrate that, with a suitable cavity design and finely tailored balance of gain, dispersion, and nonlinearity, such a laser can be operated in a subcritical mode, right beneath the soliton blowup threshold, providing an efficient source of sub-100-fs 15–20 MHz repetition-rate pulses with energies as high as 33 nJ.

Este estudo investiga a relação entre o disclosure e os níveis de internacionalização das empresas brasileiras listadas em bolsa no período de 2015 a 2017. O trabalho envolveu a construção de um índice de disclosure voluntário (IDV) com base em orientações da Organização das Nações Unidas (ONU) e da United Nations Conference on Trade and Development (UNCTAD) direcionadas ao mercado brasileiro. O IDV envolveu oito aspectos, tais como estimativas contábeis críticas; conflitos de interesse no conselho de administração; e, disponibilização de relatório anual, enquanto o nível de internacionalização das firmas foi mensurado de três formas (emissões de ADRs, receitas com exportações e participação estrangeira no capital social). O método de análise envolveu regressão com dados em painel visando identificar o impacto da internacionalização sobre o IDV, sendo que tal modelo foi investigado em três momentos distintos: usando toda a amostra e também para duas sub-amostras, uma de empresas internacionalizadas e outra de empresas não internacionalizadas. Como principais resultados, considerando a amostra geral, observou-se que empresas com maior nível de internacionalização apresentam maior nível de disclosure voluntário. Para a sub-amostra de empresas internacionalizadas, encontrou-se uma relação positiva e significativa entre emissão de ADRs, exportações e participação de estrangeiros no capital social com o índice de disclosure construído no trabalho. A partir deste estudo, infere-se que as organizações, sejam nacionais ou multinacionais, deveriam usar as estratégias e mecanismos de disclosure para estruturar e delinear adequadamente seu sistema de informações antes de buscarem consolidar suas estratégias de internacionalização.

As he neared 80 Russell was more financially secure than he had been for decades. But to remain so he needed to maintain his prodigious output as a writer, broadcaster and lecturer (see Papers 26, forthcoming). Meanwhile, the breakdown of his third marriage threatened to undermine his much-improved financial position. The monetary concerns addressed in both the text prepared by Russell and the related commentary hint at a lifetime’s scrupulous regard for his personal finances.
Análisis y regulación del lobby en la Unión Europea
Authors: Oliver González Ana Belén 
Published: January 2020

Actualmente hay miles de grupos de lobbies registrados en Bruselas. El registro de lobbies en la UE es voluntario, no establece sanciones para aquellos grupos que decidan no hacerlo. Factor determinante en la política de transparencia y ética en el proceso de toma de decisiones. El lobby es una actividad opaca por su propia naturaleza, que aunque necesaria para el ejercicio de la democracia, está mediada por el manejo de información –algunas veces de forma privilegiada– que reducen la maniobrabilidad democrática de actores que de por sí no han sido electos para el cargo que ocupan y son más susceptibles a presiones. El objetivo general de este estudio es analizar la regulación del lobby en la UE. Los objetivos específicos son describir las principales características de los lobbies en las instituciones comunitarias, identificar el marco regulatorio comunitario para el ejercicio de lobbies en dichas instituciones. La regulación del lobby ha sido más una respuesta política a la desafección ciudadana que una medida de coerción institucional. No existe un marco homogéneo ni de evaluación ni de sujeción que no sea susceptible de vulneración por parte del ejército lobista permanente en Bruselas, como tampoco hay un marco único en cada Estado. Se trata en general de mecanismos novedosos para regular un oficio que hasta no emerger como parte de la crisis de 2008 no constituyó un problema; muy por el contrario, sigue siendo visto como parte fundamental.

Published: January 2020

Neural stem cells (NSCs) persist throughout life in the subventricular zone (SVZ) neurogenic niche of the lateral ventricles as Type B1 cells in adult mice. Maintaining this population of NSCs depends on the balance between quiescence and self-renewing or self-depleting cell divisions. Interactions between B1 cells and the surrounding niche are important in regulating this balance, but the mechanisms governing these processes have not been fully elucidated. The cytoplasmic FMRP-interacting protein (Cyfip1) regulates apical-basal polarity in the embryonic brain. Loss of Cyfip1 during embryonic development in mice disrupts the embryonic niche and affects cortical neurogenesis. However, a direct role for Cyfip1 in the regulation of adult NSCs has not been established. Here, we demonstrate that Cyfip1 expression is preferentially localized to B1 cells in the adult mouse SVZ. Loss ofCyfip1in the embryonic mouse brain results in altered adult SVZ architecture and expansion of the adult B1 cell population at the ventricular surface. Furthermore, acute deletion ofCyfip1in adult NSCs results in a rapid change in adherens junction proteins as well as increased proliferation and number of B1 cells at the ventricular surface. Together, these data indicate that Cyfip1 plays a critical role in the formation and maintenance of the adult SVZ niche; furthermore, deletion ofCyfip1unleashes the capacity of adult B1 cells for symmetric renewal to increase the adult NSC pool.SIGNIFICANCE STATEMENTNeural stem cells (NSCs) persist in the subventricular zone of the lateral ventricles in adult mammals, and the size of this population is determined by the balance between quiescence and self-depleting or renewing cell division. The mechanisms regulating these processes are not fully understood. This study establishes that the cytoplasmic FMRP interacting protein 1 (Cyfip1) regulates NSC fate decisions in the adult subventricular zone and adult NSCs that are quiescent or typically undergo self-depleting divisions retain the ability to self-renew. These results contribute to our understanding of how adult NSCs are regulated throughout life and has potential implications for human brain disorders.
Urinary steroid profiling in diagnostic evaluation of an unusual adrenal mass
Authors: Lenders N F , Greenfield J R 
Published: January 2020

Summary
Adrenal oncocytomas are rare tumours, with only approximately 160 cases reported in the literature. We report the use of urinary steroid profiling as part of their diagnostic evaluation and prognostication. A 45-year-old woman presented with clinical features of hyperandrogenism. Serum biochemistry confirmed androgen excess and computed tomography (CT) demonstrated a 3.2 cm adrenal tumour with density 39 HU pre-contrast. Urine steroid profiling showed elevated tetrahydro-11 deoxycortisol (THS), which is associated with adrenal malignancy. Laparoscopic adrenalectomy was performed, and histopathology diagnosed adrenal oncocytoma. Serum and urinary biochemistry resolved post-operatively and remained normal at 1-year follow-up.

Learning points:

Differential diagnosis of adrenal masses is challenging. Current techniques for differentiating between tumour types lack sensitivity and specificity.

24-h urinary steroid profiling is a useful tool for reflecting steroid output from adrenal glands. Gas chromatography-mass spectrometry (GC-MS) of urinary steroid metabolites has sensitivity and specificity of 90% for diagnosing adrenocortical carcinoma.

Adrenal oncocytoma are rare tumours. Differentiating between benign and malignant types is difficult. Data guiding prognostication and management are sparse.
