Published: March 2021

Objectives: This study aimed to assess how menstrual cycle phase and extended menstrual cycle length influence the incidence of injuries in international footballers.Methods: Over a 4-year period, injuries from England international footballers at training camps or matches were recorded, alongside self-reported information on menstrual cycle characteristics at the point of injury. Injuries in eumenorrheic players were categorized into early follicular, late follicular, or luteal phase. Frequencies were also compared between injuries recorded during the typical cycle and those that occurred after the cycle would be expected to have finished. Injury incidence rates (per 1,000 person days) and injury incidence rate ratios were calculated for each phase for all injuries and injuries stratified by type.Results: One hundred fifty-six injuries from 113 players were eligible for analysis. Injury incidence rates per 1,000 person-days were 31.9 in the follicular, 46.8 in the late follicular, and 35.4 in the luteal phase, resulting in injury incidence rate ratios of 1.47 (Late follicular:Follicular), 1.11 (Luteal:Follicular), and 0.76 (Luteal:Late follicular). Injury incident rate ratios showed that muscle and tendon injury rates were 88% greater in the late follicular phase compared to the follicular phase, with muscle rupture/tear/strain/cramps and tendon injuries/ruptures occurring over twice as often during the late follicular phase compared to other phases 20% of injuries were reported as occurring when athletes were “overdue” menses.Conclusion: Muscle and tendon injuries occurred almost twice as often in the late follicular phase compared to the early follicular or luteal phase. Injury risk may be elevated in typically eumenorrheic women in the days after their next menstruation was expected to start.

Authors: Mori Kentaro , Yamashita Soichi , Sekiguchi Masahiro 
Published: March 2021

Abstract
An innovative 3D packaging and integration technology with a newly developed photosensitive mold material was successfully demonstrated. This technology needs neither a tall Cu pillar electroplating nor a laser drilling. A test die was mounted face up on a substrate, then a more than 100 μm thick photosensitive mold film was laminated on the whole substrate. The lithography process on the mold film was executed to make openings with depth of 10 μm on the embedded die, and with depth of 110 μm on the substrate. The Cu redistribution layer formed the electrical contacts between the die and the substrate through the photosensitive vias with different diameters and depths. The developed 3D package passed 1000 thermal cycles at −55/125 °C. This work disclosed future capability of a fan-out process using a photosensitive mold, thereby realizing a rapid growth of 3D integrated modules.

Published: March 2021

Abstract
This paper presents a self-bias NAND (SBNAND) gate and its application to a non-overlapping (NOL) clock generator for extremely low-voltage CMOS LSIs. The SBNAND, consisting of a main NAND gate and feedback inverter, improves the output performance at extremely low supply voltage V
DD by controlling the body-bias voltages V
BS of the main NAND gate. Measurements of a proof-of-concept chip demonstrated that our proposed NOL clock generator using SBNANDs can operate at the extremely low V
DD of 60 mV.

Runaway Stars as Possible Sources of the Elliptical Ring Structures in NGC 7538
Authors: Fenske Josephine , Arakawa Jason , Fallscheer Cassandra , Francesco James Di 
Published: March 2021

Abstract
Two large, ∼500 M
☉ elliptical ring structures have been identified in the high-mass star-forming region NGC 7538. The origin of these ring structures is unknown, so we investigate the possibility that a runaway O- or B-type star may have originated in or passed through the region and created either or both of the ring structures via stellar wind. In testing this hypothesis, we identify one candidate star, BD +61 2408, that may have formed the northern ring. It is a B3e star with a mass of ∼8 M
☉ and a surface temperature of ∼20,000 K. Its position, motion, timescale, and spectral type are all consistent with the star being a candidate for having formed one of the ring structures in NGC 7538.
Charging and Electromagnetic Radiation during the Inspiral of a Black Hole–Neutron Star Binary
Authors: Chen K. , Dai Z. G. 
Published: March 2021

Abstract
Because mergers of black hole–neutron star (BH–NS) binaries are widely argued to produce both gravitational and electromagnetic waves, these binaries are among the most attractive systems in the era of multi-messenger astronomy. In this paper we explore the charging processes of a moving BH in two types of charged surroundings and propose a new charging scenario differing from the elegant mechanism of Wald. During the inspiral of such a binary, the NS is strongly magnetized and the BH is moving inward. By considering this moving BH charging scenario, we find that the BH will increasingly accumulate enough net charge to light up the binary system at the inspiral stage. This charging process is universal no matter whether the BH spins or not. We show that our BH charging scenario can physically explain the BH’s unipolar inductor mechanism in a BH–NS binary system. We calculate electromagnetic emission luminosities due to various energy dissipation mechanisms and find that the electric dipole radiation of the BH makes a dominant contribution to electromagnetic emission at the final stage of inspiral if the BH spins slowly.
A Theoretical Framework for the Mass Distribution of Gas Giant Planets Forming through the Core Accretion Paradigm
Authors: Adams Fred C. , Meyer Michael R. , Adams Arthur D. 
Published: March 2021

Abstract
This paper constructs a theoretical framework for calculating the distribution of masses for gas giant planets forming via the core accretion paradigm. Starting with known properties of circumstellar disks, we present models for the planetary mass distribution over the range 0.1M
J ≤ M
p < 10M
J. If the circumstellar disk lifetime is solely responsible for the end of planetary mass accretion, the observed (nearly) exponential distribution of disk lifetime would imprint an exponential falloff in the planetary mass function. This result is in apparent conflict with observations, which suggest that the mass distribution has a (nearly) power-law form of

, with an index of p ≈ 1.3, over the relevant planetary mass range (and for stellar masses ∼0.5–2M
⊙). The mass accretion rate onto the planet depends on the fraction of the (circumstellar) disk accretion flow that enters the Hill sphere, and on the efficiency with which the planet captures the incoming material. Models for the planetary mass function that include distributions for these efficiencies, with uninformed priors, can produce nearly power-law behavior, consistent with current observations. The disk lifetimes, accretion rates, and other input parameters depend on the mass of the host star. We show how these variations lead to different forms for the planetary mass function for different stellar masses. Compared to stars with masses M
* = 0.5–2M
⊙, stars with smaller masses are predicted to have a steeper planetary mass function (fewer large planets).

Thunbergia grandiflorabelongs to the family Acanthaceae and is a widely distributed dicotyledonous plant in tropical and subtropical regions. Three isolates ofAllophoma(Dothideomycetes, Pleosporales, Didymellaceae) were collected from leaves ofT. grandiflorain Guangxi Province, China.Phylogenetic analyses of a combined ITS–LSU–rpb2–tub2dataset indicate that one of our three strains represents an undescribed species with close affinity toA. minorand the other two strains clustered amongst other isolates ofA. pterospermicola. Evidence from morphology and sequence analysis indicates that GUCC 2070.7 is a new species that we introduce here asA. thunbergiae. This is the first report about taxa ofAllophomafrom this host plant.
High Grade Glioma Surgery - Clinical Aspects and Prognosis
Authors: Mladenovsk Milan , Valkov Iliya , Ovcharov Mladen , Vasilev Nikolay , Duhlenski Iliya 
Published: March 2021

Introduction: High grade gliomas (HGG) are a group of tumors with infiltrative nature in general. Surgery is the first step in their treatment. It can be beneficial in two aspects: firstly, in establishing normal intracranial pressure and, secondly, in reducing the tumour volume. The choice of method depends on the location of the lesion, the expected grade of malignancy, and the general condition of the patient. Despite constant development of neuro-oncology and microsurgical techniques, the 5-year survival rate in patients with HGG remains less than 10% and the median survival is still less than 2 years.&nbsp;
Aim: At present, there is no final therapeutic &ldquo;segment&rdquo; to provide a better outcome than the complex treatment of HGG. Moreover, the treatment&rsquo;s relative efficacy and recurrence of these tumours carry an additional problem. The aim of this study was to estimate the overall survival of patients with HGG operated in our clinic and compare it with literature data.&nbsp;
Materials and methods: One hundred twenty-one cranial operations for HGG were reviewed (conducted between 2014 and 2019). Summary characteristics of the various parameters were presented in respect to the radical nature of the operative intervention using Kaplan-Meier analysis and chi square tests. All patients were followed up at regular check-ups.
Results: HGGs were 103 or 85.12% of all gliomas operated for the 2014-2019 period. The most common cases were in the 51 to 60 age group. The cases in men were twice as common. The most common localization of the neoplasm is in the temporal region (36.36%) and the rarest was found in the occipital region (3.30%). It was estimated that our operated patients with HGG had 12.23 months over-all survival. Gross total resected patients had a median survival (OS) of 14.53 months, while subtotal resected patients had a median survival (OS) of 10.44 months. It is estimated 7.97 months free tumor survival period (time to relapse - FTS) for our operated patients with HGG. Gross total resected patients had a median FTS of 10.88 months, while subtotal resected patients had median FTS of 5.70 months. We noticed permanent new neurological deficit (NND) in 20 patients (19.45%) operated with GTR, and in 5 patients (4.85%) operated with STR.&nbsp;
Conclusions: Median survival - OS, free tumor survival period - FTS and new neurological deficit - NND were statistically significant (p<0.05) with extent of resection &ndash; GTR or STR in our study. Maximal safe radical (total) or supratotal resection is preferred in treating HGG.&nbsp;

People with disabilities and the elderly face difficulties to fulfill their accessibility needs in their daily life routines, mainly when they have an emergency demanding speedy and specific assistance. This article proposes the SafeFollowing, a collaborative model to help people with disabilities and the elderly in smart assistive cities. The main contribution of this work is the specification of a decentralized model of ubiquitous accessibility, which involves public agents and volunteers to attend the users’ requests. SafeFollowing also allows the use of police vehicles mapping, in order to provide a specific follow-up in adverse situations of daily life. The model was validated through experiments in real case scenarios by 14 public agents and 11 elderly and people with disabilities. The results showed that 100% of evaluators (users and agents) stated that the model was useful and 82% of users and 100% of agents considered that SafeFollowing was easy to use. The experiments also allowed the learning of 5 relevant lessons on technological and usability aspects of SafeFollowing that are recorded in this article.

ObjectiveIn rheumatoid arthritis (RA), evidence regarding the effectiveness of a second biologic disease-modifying antirheumatic drug (bDMARD) in patients whose first-ever bDMARD was a non–tumor necrosis factor inhibitor (TNFi) bDMARD is limited. The objective of this study was therefore to assess the outcome of a second bDMARD (non-TNFi: rituximab [RTX], abatacept [ABA], or tocilizumab [TCZ], separately; and TNFi) after failure of a non-TNFi bDMARD as first bDMARD.MethodsWe identified patients with RA from the 5 Nordic biologics registers who started treatment with a non-TNFi as first-ever bDMARD but switched to a second bDMARD. For the second bDMARD, we assessed drug survival (at 6 and 12 months) and primary response (at 6 months).ResultsWe included 620 patients starting a second bDMARD (ABA 86, RTX 40, TCZ 67, and TNFi 427) following failure of a first non-TNFi bDMARD. At 6 and 12 months after start of their second bDMARD, approximately 70% and 60%, respectively, remained on treatment, and at 6 months, less than one-third of patients were still on their second bDMARD and had reached low disease activity or remission according to the Disease Activity Score in 28 joints. For those patients whose second bMDARD was a TNFi, the corresponding proportion was slightly higher (40%).ConclusionThe drug survival and primary response of a second bDMARD in patients with RA switching due to failure of a non-TNFi bDMARD as first bDMARD is modest. Some patients may benefit from TNFi when used after failure of a non-TNFi as first bDMARD.
