Parton distributions from LHC, HERA, Tevatron and fixed target data: MSHT20 PDFs
Authors: Bailey S. , Cridge T. , Harland-Lang L. A. , Martin A. D. , Thorne R. S. 
Published: April 2021

AbstractWe present the new MSHT20 set of parton distribution functions (PDFs) of the proton, determined from global analyses of the available hard scattering data. The PDFs are made available at NNLO, NLO, and LO, and supersede the MMHT14 sets. They are obtained using the same basic framework, but the parameterisation is now adapted and extended, and there are 32 pairs of eigenvector PDFs. We also include a large number of new data sets: from the final HERA combined data on total and heavy flavour structure functions, to final Tevatron data, and in particular a significant number of new LHC 7 and 8 TeV data sets on vector boson production, inclusive jets and top quark distributions. We include up to NNLO QCD corrections for all data sets that play a major role in the fit, and NLO EW corrections where relevant. We find that these updates have an important impact on the PDFs, and for the first time the NNLO fit is strongly favoured over the NLO, reflecting the wider range and in particular increased precision of data included in the fit. There are some changes to central values and a significant reduction in the uncertainties of the PDFs in many, though not all, cases. Nonetheless, the PDFs and the resulting predictions are generally within one standard deviation of the MMHT14 results. The major changes are the$$u-d$$u-dvalence quark difference at smallx, due to the improved parameterisation and new precise data, the$${\bar{d}}, {\bar{u}}$$d¯,u¯difference at smallx, due to a much improved parameterisation, and the strange quark PDF due to the effect of LHCW, Zdata and inclusion of new NNLO corrections for dimuon production in neutrino DIS. We discuss the phenomenological impact of our results, and in general find reduced uncertainties in predictions for processes such as Higgs, top quark pair andW, Zproduction at post LHC Run-II energies.
Accurate modeling of the strong and weak lensing profiles for the galaxy clusters Abell 1689 and 1835

Published: April 2021

AbstractAn accurate, spherically symmetric description of the mass distribution is presented for two quite virialized galaxy clusters, Abell 1689 and Abell 1835. A suitable regularization of the small eigenvalues of the covariance matrices is introduced. A stretched exponential profile is assumed for the brightest cluster galaxy. A similar stretched exponential for the dark matter and halo galaxies combined, functions well, as do thermal fermions for the dark matter and a standard profile for the halo galaxies. To discriminate between them, sensitive tests have been identified and applied. A definite verdict can follow from sharp data near the cluster centers and beyond 1 Mpc.
Fast estimation on the pressure of detonation products of cyclotetramethylene tetranitramine through molecular dynamics simulations
Authors: Song Linlin , Huo Xiangyu , Zhang Li , Xie Yujuan , Yang Mingli 
Published: April 2021

The equation of states (EOS) that correlates the pressure, volume and temperature (PVT) of detonation products is indispensable in the numerical modeling of blasting performances of energetic materials. Based on extensive molecular dynamics simulations on the mixtures of CO2, H2O, N2, CO and H2, which are the main components of detonation products of cyclotetramethylene tetranitramine (HMX), the relation of pressure with density, temperature and composition is derived in the range of 1.4–2.2 g/cm3 for density, 3000–4400 K for temperature and 8–40 GPa for pressure. The proposed EOS exhibits good general applicability under the studied conditions and reasonable agreement with the experimentally established Becker–Kistiakowsky–Wilson (BKW) equation. Although several approximations are applied in the computations and some deviations remains, it suggests an effective and feasible approach to establish the EOS for detonation products of energetic materials by means of molecular modeling.
Is There a Place for Spinal Cord Stimulation in the Management of Patients with Multiple Sclerosis? A Systematic Review of the Literature
Authors: Rapisarda Alessandro , Ioannoni Eleonora , Izzo Alessandro , D’Ercole Manuela , Montano Nicola 
Published: April 2021

Objective. Spinal cord stimulation (SCS) is a minimally invasive technique mainly used to treat neuropathic pain associated with failed back surgery syndrome. However, this therapy has been utilized to treat other chronic painful conditions, such as pain associated with multiple sclerosis (MS). Nonetheless, the efficacy of SCS in MS patients has not been fully established. In fact, in most of SCS series, MS patients represent only a subset of a bigger cohort which comprises different causes of pain, motor disorder, and other functional limitations. The aim of our study was to systematically review the literature to evaluate the effectiveness of SCS in MS patients. Methods. A literature search was performed through different databases (PubMed, Scopus, and Embase) using the following terms: “multiple sclerosis,” “spinal cord stimulation,” and “dorsal column stimulation,” according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. Results. A total of 452 articles were reviewed, and 7 studies were included in the present analysis. 373 MS patients were submitted to a stimulation trial, and 82 MS patients underwent a de novo implantation. 285/373 (76.4%) of cases submitted to the SCS trial were enrolled for permanent stimulation. We found a long-lasting improvement in 193/346 (55.8%) MS patients with motor disorders, in 90/134 (67.13%) MS patients with urinary dysfunction, and in 28/34 (82.35%) MS patients with neuropathic pain. The efficacy of SCS was higher for urinary dysfunction (

p

= 0.0144) and neuropathic pain (

p

= 0.0030) compared with motor disorders. Conclusions. Our systematic review evidences that SCS is effective in MS patients. Urinary dysfunction and pain symptoms seem to be most responsive to SCS. Further studies are needed to improve the patient selection and clarify the best timing to perform SCS in these patients.
Alternate without alternative: neither preference nor learning explains behaviour of C57BL/6J mice in the T-maze
Authors: Habedank Anne , Kahnau Pia , Lewejohann Lars 
Published: April 2021

Abstract
In rodents, the T-maze is commonly used to investigate spontaneous alternating behaviour, but it can also be used to investigate preference between goods. However, for T-maze preference tests with mice there is no recommended protocol and researchers frequently report reproduction difficulties. Here, we tried to develop an efficient protocol with female C57BL/6J CrL mice for preference tests. We used two different designs, adapting habituation, cues and trial timing. However, in both experiments mice did not show any preference, although we used goods which we knew mice find rewarding. Instead, they alternated choices indicating that exploratory behaviour overruled preference. We argue that this behavioural strategy has evolved as an adaptive trait in saturated conditions where there is no need to take the reward immediately. Therefore, we deem the T-maze unsuitable for preference testing with the procedures we used here.
Second Wife, Second Life: Polygyny among Migrants from Central Asia in Moscow
Authors: Cieślewska Anna 
Published: April 2021

Abstract
This article focuses on transnational polygamous marriages of migrants in Russia and how transnational polygynous practices influence people’s understanding of marriage, love and family. The paper shows how polygamous migrant marriages are negotiated between families, by presenting the perspective of individuals involved in such relationships in Russia. It argues that transborder relationships contribute to the transformation of social interactions. People function in two or sometimes more countries, creating opportunities for parallel partnering or other options that influence family networks in the migrants’ countries of origin.
Incorporating features from the Stochastic Time-Inverted Lagrangian Transport (STILT) model into the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model: a unified dispersion model for time-forward and time-reversed applications

Published: April 2021

AbstractThe Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model is a state-of-the-science atmospheric dispersion model that is developed and maintained at the National Oceanic Atmospheric Administration’s (NOAA) Air Resources Laboratory (ARL). In the early 2000s, HYSPLIT served as the starting point for development of the Stochastic Time-Inverted Lagrangian Transport (STILT) model that emphasizes backward-in-time dispersion simulations to determine source regions of receptors. STILT continued its separate development and gained a wide user base. Since STILT was built on a now outdated version of HYSPLIT and lacks long-term institutional support to maintain the model, incorporating STILT features into HYSPLIT allows these features to stay up to date. This paper describes the STILT features incorporated into HYSPLIT, which include: a new vertical interpolation algorithm for WRF derived meteorological input files, a detailed algorithm for estimating boundary layer height, a new turbulence parameterization, a vertical Lagrangian timescale that varies in time and space, a complex dispersion algorithm, and two new convection schemes. An evaluation of these new features was performed using tracer release data from the Cross Appalachian Tracer Experiment and the Across North America Tracer Experiment. Results show the dispersion module from STILT, which takes up to double the amount of time to run, is less dispersive in the vertical and in better agreement with observations than the existing HYSPLIT option. The other new modeling features from STILT were not consistently statistically different than existing HYSPLIT options. Forward-time simulations from the new model were also compared against backward-time equivalents and found to be statistically comparable to one another.

Published: April 2021

Objective: Complications associated with intracranial vault compromise can be neurologically and systemically devastating. Primary and secondary repair of these deficits require an air and watertight barrier between the intracranial and extracranial environments. This study evaluated the outcomes and utility of using intracranial free tissue transfer as both primary and salvage surgical repair of reconstruction. Methods: A retrospective review was performed of all subjects who underwent intracranial free tissue transfer as primary or salvage repair. Results: A total of 13 intracranial free tissue transfers were performed on 11 subjects: osteocutaneous radial forearm free flaps (n = 6), partial myofascial rectus abdominis flaps (n = 5), temporoparietal fascia flap (n = 1), and serratus anterior myofascial flap (n = 1). Primary reconstruction was performed on 4 subjects with the remaining being salvage repair. Indications for surgery included neoplasm (n = 6 of 11), ballistic trauma (n = 3 of 11), motor vehicle accident (n = 1 of 11), and infection (n = 1 of 11). Three subjects required additional surgical repair for CSF leak and pneumocephalus, with 2 subjects requiring an additional free tissue transfer at a different site. Conclusion: In our experience, free tissue transfer is an effective primary and salvage surgical technique in the reconstruction of complex intracranial problems.
Knowledge and attitude towards home treatment among referring healthcare professionals and self-referring patients to a psychiatric hospital: Better information is needed
Authors: Mötteli Sonja , Risch Ladina , Hotzy Florian , Vetter Stefan 
Published: April 2021

Background: Home treatment (HT) is a patient-centred and cost-effective alternative to acute psychiatric inpatient care. However, the progress of its implementation and utilisation in routine care is slow. Aims: The aim of this study was to examine the knowledge and attitude towards HT among healthcare professionals. Method: This observational study included telephone-based semi-structured interviews of 140 referring healthcare professionals including 35 self-referring patients to a large psychiatric hospital in Switzerland during 6 months in 2020. We assessed their knowledge, attitude and experience with HT along with sociodemographic characteristics, professional background and the intention for the referral. We completed the interviews with routine medical data of the referred patients such as diagnoses or symptom severity. Results: Regarding referrals for inpatient treatment (involuntary and voluntary), half of the referring healthcare professionals and 80% of the self-referring patients had no prior experience or knowledge of HT. Knowledge of HT differed in the order of the participants’ working places. We found that most participants were uncertain about the inclusion/exclusion criteria for HT. Despite the low levels of knowledge, attitudes towards HT were overall positive. Conclusions: Our results indicate that a proportion of the patients referred for inpatient treatment might have been eligible for HT too. The referring healthcare professionals’ and patients’ unfamiliarity and uncertainty with HT seems to be an important reason that home-based treatment approaches are still underused, although they are viewed very positively. Besides providing more information to potential referring health professionals, psychiatric hospitals should always carry out a standardized evaluation if HT is an option in patients who are referred for inpatient treatment.

To investigate the sociological, environmental, and economic impact of hormonally active contraceptives, a series of comprehensive literature surveys were employed. Sociological effects are discussed including abortion, exploitation of women, a weakening of marriage, and an increase in divorce with deleterious effects on children such as child poverty, poorer health, lower educational achievement, suicide risks, drug and alcohol abuse, criminality, and incarceration, among others. The environmental impact is discussed briefly and includes the feminization and trans-gendering of male fish downstream from the effluent of city wastewater treatment plants with declining fish populations. The potential economic impact of most of these side effects is estimated based on epidemiologic data and published estimates of costs of caring for the diseases which are linked to the use of hormonally active contraceptives. Hormonally active contraceptives appear to have a deleterious impact on multiple aspects of women’s health as well as negative economic and environmental impacts. These risks can be avoided through the use of nonhormonal methods and need to be more clearly conveyed to the public. Summary: Hormonal contraceptives have wide-ranging effects. The potential economic impact of the medical side effects is estimated. Sociological effects are discussed including abortion, exploitation of women, a weakening of marriage and an increase in divorce with negative effects on children such as child poverty, poorer health, lower educational achievement, suicide risks, drug and alcohol abuse, criminality and incarceration among others. The environmental impact includes hormonal effects on fish with declining fish populations. Women seeking birth control have a right to know about how to avoid these risks by using effective hormone-free methods like Fertility Awareness Methods.
A Head-to-Head Comparison of Three Self-Help Techniques to Reduce Body-Focused Repetitive Behaviors
Authors: Moritz Steffen , Penney Danielle , Ahmed Kaser , Schmotz Stella 
Published: April 2021

Body-focused repetitive behaviors (BFRBs) include skin picking, trichotillomania, nail biting and cavitadaxia/lip-cheek biting, among other behaviors. For the first time, we compared three different self-help techniques aimed at reducing BFRBs. We explored the acceptance and preliminary efficacy of the approaches and whether the techniques exerted differential effects depending on BFRB-type. A total of 113 participants with at least one BFRB were randomly allocated to either habit reversal training (HRT; active elements: awareness and competing response training), decoupling (DC) or decoupling in sensu (DC-is). Reassessment was conducted 4 weeks later. The Generic Body-Focused Repetitive Behavior Scale (GBS) served as the primary outcome. The completion rate was best for DC-is (68.6%) as compared to HRT (57.1%) and DC (53.5%). A total of 34.8% of completers in the DC group showed an improvement of at least 35% on the GBS compared to 10.0% in the HRT and 23.3% in the DC-is group. In accordance with previous work, moderator analyses showed that improvement under DC is best for non-skin-pickers. A dose-effect relationship emerged, particularly for HRT. Subjective appraisal ratings were more favorable for DC-is and HRT than for DC. With respect to completion rate, subjective appraisal and symptom improvement, DC-is yielded consistently satisfactory results, whereas HRT showed good subjective but rather poor objective improvement. Those who performed DC, especially non-skin-pickers, showed good improvement but overall completion and subjective efficacy were low. Future studies should investigate whether the three techniques exert add-on effects when combined and whether demonstration via new media (e.g., video) will augment comprehensibility and thus efficacy of the techniques.
Nasal Septal Swell Body: A Distinctive Structure in the Nasal Cavity
Authors: Meng Xiangming , Zhu Guochen 
Published: April 2021

Objectives: The nasal septal swell body (NSB), also known as the nasal septal turbinate, is located in the anterior part of the nasal septum. This study is a narrative review of the existing knowledge on recent developments in NSB. Methods: A literature search was performed using PubMed, Embase, Web of Science, Ovid, and Cochrane Library databases. Google Scholar was used to access more extensive literature. The inclusion criteria were human studies published in English. The exclusion criteria were non-English language and animal studies. Results: Of the 345 articles that were initially obtained from 5 databases and Google Scholar, 28 were included in this review. There have been many names for NSBs in the past, which still have no unified terminology recognized by professionals. Pathological investigations revealed that NSB contains a certain amount of sinusoidal blood components. Nasal septal swell body is closely related to the internal nasal valve. Imaging studies have found that the size of NSB is associated with nasal diseases, and NSB hypertrophy can cause anatomic obstruction. In recent years, several procedures for NSB have been reported, and preliminary effectiveness has been achieved. However, the long-term outcomes of volume reduction techniques remain unproven. Conclusions: The NSB is a distinct anatomic structure that may contribute to nasal obstruction and may be reduced surgically with unclear long-term results. Although being investigated for over a century, the unique physiological roles of NSB are not yet fully understood. More evidence is needed to elucidate its physiological effects.
Olfactory Cleft Opacification in COVID-19 Related Smell Loss: CT Findings and Correlation With Objective Testing
Authors: Yıldız Erkan , Balcı Aydın , Selendili Okan , Kuzu Selçuk 
Published: April 2021

Objectives: Besides the common symptoms of the coronavirus disease 2019 (COVID-19) including fever, shortness of breath, and cough, a “sudden loss of smell” has recently been added as a diagnostic symptom. The relationship between paranasal sinus computed tomography (PNS CT) and sudden loss of smell in COVID-19 was examined. Materials and Methods: Two groups were selected for the study, the COVID-19 and the control groups. The control group consisted of 40 patients who applied to our clinic with headache and therefore underwent PNS CT. The other group consisted of 40 patients with COVID-19 who were diagnosed with sudden loss of smell with the Connecticut Chemosensory Clinical Research Center (CCCRC) olfactory test. Clinical and demographic characteristics, tomography results, and olfactory test scores of patients with COVID-19 loss of smell and control group patients were recorded. The relationship between CT changes in the olfactory cleft and the degree of loss of smell was evaluated. The “Opacification in the olfactory cleft” was accepted as a positive CT finding. Results: Comparison of patients with COVID-19 who had a loss of smell and the control group indicated that a significant difference was observed in terms of CT findings ( P = .022). When we evaluated the paranasal CTs obtained from our patients with loss of smell, the CT of 13 patients showed pathological findings ( P < .05). As the COVID-19 progressed (pneumonia and respiratory failure), the degree of loss of smell increased ( P < .05). A statistically significant relationship was found between the CCCRC score and the presence of PNS CT findings ( P = .0012). Conclusion: The PNS CT findings are significant in patients with COVID-19 with a loss of smell and were significantly associated with the degree of loss of smell. In patients with olfactory loss due to COVID-19, PNS CT can help in diagnosis. However, for this imaging to be diagnostic, a larger patient series is needed.

Published: April 2021

ObjectiveWe performed a systematic review and meta‐analysis of deep lobe parotid tumors to evaluate their unique characteristics.Data SourcesPubMed/Medline, Embase, Web of Sciences, and Cochrane Library databases were queried for relevant literature.Review MethodsStudies were individually assessed by 2 independent reviewers. Risk of bias was assessed with the Cochrane bias tool, GRADE criteria, and MINORS criteria. Results were reported according to the PRISMA guidelines. Statistical analysis was performed by comparing rates of malignancy between deep and superficial lobe tumors.ResultsIn total, 8 studies including 379 deep lobe parotid tumors met inclusion criteria. Mean age at diagnosis was 44.9 years. Computed tomography scan was the most common imaging modality. Preoperative diagnostic fine‐needle aspiration was utilized in 39.4% of patients and demonstrated high sensitivity for malignant disease. The most common approach was subtotal parotidectomy with facial nerve preservation (58.9%). The rate of malignancy was 26.6%, which was significantly higher than that of the superficial lobe tumors in this study (risk ratio, 1.25; 95% CI, 1.01‐1.56). The rate of temporary postoperative facial nerve weakness between deep and superficial lobe tumors was 32.5% and 11.7%, respectively.ConclusionDeep lobe parotid tumors had a 26.6% rate of malignancy. On meta‐analysis, deep lobe tumors appeared to have higher rates of malignancy than superficial lobe tumors. Surgical excision of deep lobe tumors showed increased rates of temporary facial nerve paresis as compared with superficial lobe tumors. Computed tomography scan was the most common imaging modality. There were limited data regarding the utility of fine‐needle aspiration.
