ZusammenfassungEinleitung Alkoholkonsum in der Schwangerschaft birgt viele Risiken für das ungeborene Kind. Trotz präventiver Maßnahmen konsumieren manche Schwangere Alkohol. Diese Untersuchung zielt darauf ab, mögliche Gründe für den Konsum in der Schwangerschaft zu identifizieren und die Zuschreibung der Expert:innenrolle an medizinisches Fachpersonal durch die Betroffenen zu beleuchten.Material und Methoden In dieser Untersuchung wurden 9 Diskussionsthreads aus Onlineforen zum Thema Alkoholkonsum in der Schwangerschaft mit insgesamt 115 Diskussionsteilnehmern mittels Grounded Theory analysiert. Die diskursive Validierung der Ergebnisse erfolgte im Forschungsteam.Ergebnisse Es zeigte sich, dass die persönliche Definition der Mutterrolle Einfluss auf das Konsumverhalten hat. Frauen, die sehr um das Kindeswohl besorgt waren, konsumierten gelegentlich in Stresssituationen oder bei sozialen Anlässen, berichteten aber häufig über ein nach dem Konsum auftretendes schlechtes Gewissen. Frauen, die eigene Bedürfnisse stärker gewichteten, konsumierten eher aus Genuss oder weil sie sich durch Verbote bevormundet fühlten. Als förderliche Faktoren für die Zuschreibung der Expert:innenrolle an Gynäkolog:innen wurden eine Arzt-Patientenbeziehung auf Augenhöhe sowie eine ausführliche, non-direktive Aufklärung identifiziert. Als hinderlich zeigte sich dagegen eine paternalistische Haltung und das Aussprechen von Verboten.Diskussion Bei allen Frauen zeigte sich ein hoher Informationsbedarf zum Thema Alkoholkonsum in der Schwangerschaft. Die Arzt-Patienten-Beziehung scheint in der Informationsvermittlung eine wichtige Rolle zu spielen. Zudem wurde deutlich, dass der Unterstützungswunsch bei Frauen, die eine Abstinenz anstreben, nicht ausreichend erfüllt wird.Schlussfolgerung Der Alkoholkonsum in der Schwangerschaft sollte in der Betreuung aller Schwangeren regelmäßig angesprochen werden. Neben einer Aufklärung über die Risiken des Konsums sind Informationen zu Unterstützungsangeboten relevant.

Published: November 2020

AbstractEven though traumatic dissection of cervical arterial vessels is the major cause of stroke among adults, it is still an underdiagnosed disease in neurosurgical emergencies, since most patients do not have or present subtle clinical signs in the acute phase. The authors report two interesting cases of cervical artery dissection with different traumatic mechanisms and present a broad literature review about this subject.

Published: November 2020

Abstract
Pasteurella multocida, a zoonotic infectious pathogen, is a rare cause of mycotic aneurysms in human hosts. A 76-year-old man was admitted at our emergency unit for a superinfection of his right limb. The patient was initially treated for a knee arthritis. After a first-line antibiotherapy, the patient was referred to the vascular department for the management of a right acute limb ischemia. The work-up revealed a ruptured pseudoaneurysm of the popliteal artery. The ruptured artery was surgically explanted, and a femoropopliteal bypass was then performed. Pasteurella multocida was detected after bacterial analysis of the aneurysm. The postoperative course was uneventful. This case is the first reported case, to our knowledge, of a popliteal artery pseudoaneurysm due to Pasteurella multocida infection.

Abstract
Objectives The aim of this study was to evaluate psychological distress caused by the novel coronavirus disease 2019 (COVID-19) pandemic among the adult population residing in Pakistan.
Materials and Methods This cross-sectional survey-based study comprised 1,000 adults residing in Pakistan. A questionnaire was formulated and circulated among adult population of Pakistan, the depression and anxiety symptoms using Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) scales were assessed.
Statistical Analysis Independent t-test, cross tabulation, and regression analysis were used to identify variables having impact on PHQ-9 and GAD-7 scores. A p-value of ≤ 0.05 was considered statistically significant.
Results Among 1,000 participants, 573 were males and 427 were females who completed the survey. Majority were restricted to home for more than 40 days. Considerable number of participants reported depressive (540, 54%) and anxiety (480, 48%) symptoms. Gender, age, earnings, and occupation have significant relation with psychological distress, although similar was not found with education levels.
Conclusion Psychological distress, a concerning yet addressable issue was found among adults arising amid COVID-19 outbreak. Currently, physical health effects of COVID-19 are being looked, while mental health effects being under-addressed. This issue should be addressed to avoid any psychological impact in future.

Abstract
Objective Primary repair of posteriorly located anterior skull base (ASB) dural defects following cranial trauma is made difficult by narrow operative corridors and adherent dura mater. Inadequate closure may result in continued cerebrospinal fluid (CSF) leak and infectious sequelae. Here, we report surgical outcomes following the use of nonpenetrating titanium microclips as an adjunctive repair technique in traumatic anterior skull base dural defects extending from the olfactory groove to the tuberculum sellae.
Methods All trauma patients who underwent a bifrontal craniotomy from January 2013 to October 2019 were retrospectively reviewed. Patients with ASB defects located at posterior to the olfactory groove were analyzed. Patients with isolated frontal sinus fractures were excluded. All patients presented with CSF leak or radiographic signs of dural compromise. Patients were divided according to posterior extent of injury. Patient characteristics, imaging, surgical technique, and outcomes are reported.
Results A total of 19 patients who underwent a bifrontal craniotomy for repair of posteriorly located ASB dural defects using nonpenetrating titanium microclips were included. Defects were divided by location: olfactory groove (10/19), planum sphenoidale (6/19), and tuberculum sellae (3/19). No patients demonstrated a postoperative CSF leak. No complications related to the microclip technique was observed. Clip artifact did not compromise postoperative imaging interpretation.
Conclusion Primary repair of posteriorly located ASB dural defects is challenging due to narrow working angles and thin dura mater. Use of nonpenetrating titanium microclips for primary repair of posteriorly located dural defects is a reasonable adjunctive repair technique and was associated with no postoperative CSF leaks in this cohort.
Brain Abscess Caused by Nocardia: Case Report and Literature Review
Authors: Finger Guilherme , Gripa Maria Eduarda Conte , Cecchini Tiago Paczko Bozko , Nascimento Tobias Ludwig do 
Published: November 2020

AbstractNocardia brain abscess is a rare clinical entity, accounting for 2% of all brain abscesses, associated with high morbidity and a mortality rate 3 times higher than brain abscesses caused by other bacteria. Proper investigation and treatment, characterized by a long-term antibiotic therapy, play an important role on the outcome of the patient. The authors describe a case of a patient without neurological comorbidities who developed clinical signs of right occipital lobe impairment and seizures, whose investigation demonstrated brain abscess caused by Nocardia spp. The patient was treated surgically followed by antibiotic therapy with a great outcome after 1 year of follow-up.

Published: November 2020

AbstractThe incidence of anterior cruciate ligament (ACL) reconstruction is increasing in the United States, particularly in the older athlete. Patients who undergo ACL reconstruction are at higher risk for undergoing total knee arthroplasty (TKA) later in life. TKA in patients with prior ACL reconstruction has been associated with longer operative time due in-part to difficulty with exposure and retained hardware. Outcomes after TKA in patients with prior ACL reconstruction are not well defined, with some reports showing increased rate of complications and higher risk of reoperation compared with routine primary TKA, but these results are based on small and nonrandomized cohorts. Future research is needed to determine whether graft choice or fixation technique for ACL reconstruction influences outcomes after subsequent TKA. Furthermore, whether outcomes are affected by choice of TKA implant design for patients with prior ACL reconstruction warrants further study. This review analyzes the epidemiology, operative considerations, and outcomes of TKA following ACL reconstruction.
Peer-interaction patterns in a Chinese as a foreign language pair writing task
Authors: Zhai Mengying 
Published: November 2020

AbstractResearch on peer interaction patterns over the past three decades has provided insights regarding how relationships formed among peers can influence task performance. Six pairs of intermediate Chinese learners participating in a collaborative writing task were recruited, and their pair-interaction patterns were investigated for detailed evidence of how such patterns were constructed through their co-participation measured by two indices proposed byStorch (2002a), equality and mutuality. Furthermore, taking a Conversation Analytical (CA) perspective, this study also examined the fine-grained detail of several interactional practices displaying participants’ orientation to the peer relationship. This revealed that each pair displayed a distinctive interaction pattern that was constructed through diverse participatory practices which are contingent upon the ongoing interaction as it unfolds. The findings shed new light into analyzing pair interactions in collaborative writing from a CA perspective in CFL settings and have important implications for studying interaction patterns and implementing collaborative writing tasks.

Published: November 2020

Abstract
As part of the upgrade program of the advanced Virgo interferometer, the installation of new instrumented baffles surrounding the main test masses is foreseen. As a demonstrator, and to validate the technology, the existing baffle in the area of the input mode cleaner end-mirror will be first replaced by a baffle equipped with photodiodes. This paper presents detailed simulations of the light distribution on the input mode cleaner baffle. They served to validate the proposed layout of the sensors in the baffle, and determine the light exposure of the photodiodes under different scenarios of the interferometer operations, in order to define mitigation strategies for preserving the detector integrity.
Relativity and radiation balance for the classical hydrogen atom in classical electromagnetic zero-point radiation
Authors: Boyer Timothy H 
Published: November 2020

Abstract
When teaching modern physics, every instructor must deal with the apparent failure of classical physics to prevent the radiation collapse of the nuclear atom. Here we review the understanding of the classical hydrogen atom in classical electromagnetic zero-point radiation, and emphasize the importance of special relativity. The crucial missing ingredient in earlier calculational attempts (both numerical and analytic) is the use of valid approximations to the full relativistic analysis. It is pointed out that the nonrelativistic time Fourier expansion coefficients given by Landau and Lifshitz are in error as the electromagnetic description of a charged particle in a Coulomb potential, and, because of this error, Marshall and Claverie’s conclusion regarding the failure of radiation balance is invalid. Rather, using Marshall and Claverie’s calculations, but restricted to lowest nonvanishing order in the orbital eccentricity (where the nonrelativistic orbit is a valid approximation to the fully relativistic electromagnetic orbit) radiation balance for classical electromagnetic zero-point radiation is shown to hold at the fundamental frequencies and associated first overtones.
A direct method for solving inverse Sturm–Liouville problems*
Authors: Kravchenko Vladislav V. , Torba Sergii M. 
Published: November 2020

Abstract
We consider two main inverse Sturm–Liouville problems: the problem of recovery of the potential and the boundary conditions from two spectra or from a spectral density function. A simple method for practical solution of such problems is developed, based on the transmutation operator approach, new Neumann series of Bessel functions representations for solutions and the Gelfand–Levitan equation. The method allows one to reduce the inverse Sturm–Liouville problem directly to a system of linear algebraic equations, such that the potential is recovered from the first element of the solution vector. We prove the stability of the method and show its numerical efficiency with several numerical examples.
Higgs decay to light (pseudo)scalars in the semi-constrained NMSSM *
Authors: Ma Shiquan , Wang Kun , Zhu Jingya 
Published: November 2020

Abstract
The next-to minimal supersymmetric standard model (NMSSM) with non-universal Higgs masses, i.e., the semi-constrained NMSSM (scNMSSM), extends the minimal supersymmetric standard model (MSSM) by a singlet superfield and assumes universal conditions, except for the Higgs sector. It can not only maintain the simplicity and grace of the fully constrained MSSM and NMSSM and relieve the tension they have been facing since the discovery of the 125-GeV Higgs boson but also allow for an exotic phenomenon wherein the Higgs decay into a pair of light (

) singlet-dominated (pseudo)scalars (hereafter, in this paper, we use "scalar" for both scalars and pseudoscalars, considering pseudoscalars can also be called CP-odd scalars). This condition can be classified into three scenarios according to the identitiesof the SM-like Higgs and the light scalar: (i) the light scalar is CP-odd, and the SM-like Higgs is

; (ii) the light scalar is CP-odd, and the SM-like Higgs is

; and (iii) the light scalar is CP-even, and the SM-like Higgs is

. In this work, we compare the three scenarios, checking the interesting parameter regions that lead to the scenarios, the mixing levels of the doublets and singlets, the tri-scalar coupling between the SM-like Higgs and a pair of light scalars, the branching ratio of Higgs decay to the light scalars, and sensitivities in the detection of the exotic decay at the HL-LHC and future lepton colliders such as CEPC, FCC-ee, and ILC. Finally, several interesting conclusions are drawn, which are useful for understanding the different delicate mechanisms of the exotic decay and designing colliders in future.
Slowly rotating Einstein-bumblebee black hole solution and its greybody factor in a Lorentz violation model *
Authors: Ding Chikun , Chen Xiongwen 
Published: November 2020

Abstract
We obtain an exact slowly rotating Einstein-bumblebee black hole solution by solving the corresponding

and

components of the gravitational field equations for both cases: A)

and B)

. Then, we check the other gravitational field equations and the bumblebee field motion equations using this solution. We find that for case A, there indeed exists a slowly rotating black hole solution for an arbitrary LV (Lorentz violation) coupling constant

; however, for case B, this slowly rotating solution exists if and only if coupling constant

is as small as or smaller than angular momentum a. Thus far, no full rotating black hole solution has been published; hence, the Newman-Janis algorithm cannot be used to generate a rotating solution in the Einstein-bumblebee theory. This is similar to the Einstein-aether theory, wherein only some slowly rotating black hole solutions exist. To study the effects of this broken Lorentz symmetry, we consider the black hole greybody factor and find that, for angular index

, LV constant

decreases the effective potential and enhances the absorption probability, which is similar to the results for the non-minimal derivative coupling theory.
Probing the universality of acceleration scale in modified Newtonian dynamics with SPARC galaxies *
Authors: Li Xin , Zhao Su-Ping , Lin Hai-Nan , Zhou Yong 
Published: November 2020

Abstract
We probe the universality of acceleration scale

in Milgrom's modified Newtonian dynamics (MOND) using the recently released rotation curve data from SPARC galaxies. We divide the SPARC data into different subsamples according to the morphological types of galaxies, and fit the rotation curve data of each subsample with the theoretical prediction of MOND. MOND involves an arbitrary interpolation function which connects the Newtonian region and the MOND region. Here we consider five different interpolation functions that are widely discussed in the literature. It is shown that the best-fitting

significantly depends on the interpolation functions. For a specific interpolation function,

also depends on the morphological types of galaxies, implying that

may be not a universal constant. Introducing a dipole correction to

can significantly improve the fits. The dipole directions for four of the five interpolation functions point towards an approximately consistent direction, but

still varies for different interpolation functions.
Modeling the parameters of hot radioactivity release as a result of an accident at Chernobyl nuclear power plant
Authors: Mehdi M , Panin M P , Pripachkin D A , Mohemmedi B 
Published: November 2020

Abstract
A three-dimensional Computational Fluid Dynamics (CFD) model is used to simulate the dispersion of radioactive gas from the Chernobyl accident. The most important features of the model are a totally 3-dimensional advection–diffusion equation. Computing the rise of the plume from an accident is an important point for estimating the release of radioactive gas into the atmosphere. The analysis of the plume rise at the time of the Chernobyl accident presents some special circumstances. This is caused by the very high temperature resulting from the burning of graphite. The modeling was performed using Reynolds-Averaged Navier-Stokes RANS method using the k-ε model delivered by the commercial code ANSYS-Fluent. The results of the simulation were verified against the measurements taken by aircraft.

Authors: Momot O A , Nguyen T P , Synzynys B I 
Published: November 2020

Abstract
For the generalized population of Vietnam and the cities of Dalat and Hanoi, a risk assessment is carried out for exposure to radioactive substances present in the environment. The impact of radionuclides of both natural and man-made origin, as well as various routes of their impact, are considered. The assessed results show the values of the radiological risk for the population of Vietnam, Dalat and Hanoi amount to 1.58·10−6, 1.96·10−6 and 7.19·10−5, respectively. The greatest contribution to radiological risk is made by the consumption of foods that contain natural radionuclides. The radiological risk in Vietnam from technogenic radionuclides doesn’t exceed acceptable value (5·10−5) and is much lower (14-1125 times) than that from natural radionuclides.

Authors: Nushtaeva V E , Spiridonov S I , Karpenko E I , Nushtaev S N , Kurbakov D N 
Published: November 2020

Abstract
The article presents a long-term prediction of radiation doses to members of the public and reference organisms of biota from planned radioactive atmospheric releases by the Baltic nuclear power plant with VVER-1200. The calculation of atmospheric dispersion and radiation dose to the population have performed on the basis of general models presented in the IAEA Safety Report Series No. 19. The radiation doses to non-human biota have calculated using the ERICA Tool. Annual effective dose to the population near the Baltic NPP are expected to be below 2.1 μSv. The dose rate of reference organisms will not exceed 0.6 nGy/h. The main contribution to the irradiation of both population and non-human biota will be made by 14C and 3H. It has recommended to include these radionuclides in the radioecological monitoring program of natural and agricultural ecosystems in the area where the Baltic NPP is located.
The long-term effects of combined chronic exposure to low-intensity radiofrequency electromagnetic fields and different food quantity on crustaceans Daphnia magna
Authors: Zhalnina A A , Uskalova D V , Ustenko K V , Savina N B 
Published: November 2020

Abstract
The long-term effects of chronic exposure to low-intensity radiofrequency electromagnetic fields (EMF) and different food quantity on crustaceans Daphnia magna were studied. The changes in growth, survival and fecundity of daphnia were analyzed. EMF (1 GHz; 100 mW/cm2) does not affect the growth and survival of D. magna, which is chronically exposed in the early period of ontogenesis. However, EMR reduces the fertility of irradiated daphnia and their offspring. Food conditions affect these parameters of crustaceans independently.
