A Preliminary Investigation of Social Justice Perceptions Among U.S. Speech-Language Pathologists: Clinical Implications
Authors: Unger Julia P. , DeBonis David A. , Amitrano Anthony R. 
Published: September 2021

Purpose
The purpose of this survey research is to provide preliminary data regarding speech-language pathologists' (SLPs') perceptions of the role that social justice (SJ) plays in their work. As our professional organizations call us to advocate and communicate with regulatory agencies and legislative bodies to promote quality care for all individuals, this topic has become particularly important at this time. At present, there is a lack of data in peer-reviewed publications within the discipline of communication disorders on SJ and even less regarding the perceptions of SLPs on SJ.

Method
The survey was sent to American Speech-Language-Hearing Association (ASHA)-certified SLPs, identified by the ASHA ProFind database, across six U.S. geographic regions, including both urban and rural communities. Four themes were explored through the survey: (a) importance of SJ, (b) awareness of SJ, (c) current practices related to SJ, and (d) barriers to SJ implementation.

Results
The majority of respondents view SJ as important to the profession (91.2%) and value the work of creating equality among groups (96.0%). Many SLPs are actively involved in implementing SJ principles in their own practice by accepting Medicaid (40.7%), engaging in political outreach (55.0%), and providing transdisciplinary educational outreach (77.9%). Identified barriers to incorporating SJ include time (62.7%), resources (65.6%), and finances (70.0%).

Conclusions
Working for SJ is important to a majority of the respondents, and various efforts are implemented to create equal opportunities for service to clients. Barriers continue to exist that limit the degree to which SLPs can work toward SJ. A list of actions to be considered in order to promote SJ in the field is provided.

Distribution network hosting capacity assessment: Incorporating probabilistic harmonic distortion limits using chance constrained optimal power flow
Authors: Sun Wei , Harrison Gareth P. 
Published: September 2021

AbstractThe capacity of renewable distributed generation (DG) connected in distribution networks is increasing. Use of power electronic interfaces means DG can inject harmonic currents through the point of common coupling into upstream networks. The limits stipulated in harmonic emission standards may create challenges for accommodating DG. To explore the impact of harmonic regulations on the ability of distribution networks to host DG, this work incorporates harmonic voltage constraints into a network hosting capacity assessment. A novel hosting capacity assessment approach is presented, incorporating percentile‐based harmonic compliance levels as chance constraints over multiple periods into AC optimal power flow. The case study shows that network hosting capacity for DG could be evidently lower under rigorous compliance with harmonic distortion limits, but that relaxation of the risk constraints has significant value. Furthermore, the complex inter‐connectivity between DG sites means that voltage, thermal and harmonic constraints all influence the locational feasibility for DG capacity.

Published: September 2021

Context. TOI-849b is one of the few planets populating the hot-Neptune desert and it is the densest Neptune-sized one discovered so far. Its extraordinary proximity to the host star, together with the absence of a massive H/He envelope on top of the 40.8 M⊕ rocky core, calls into question the role played by the host star in the evolution of the system.
Aims. We aim to study the impact of the host star’s rotational history on the evolution of TOI-849b, particularly focussing on the planetary migration due to dynamical tides dissipated in the stellar convective envelope, and on the high-energy stellar emission.
Methods. Rotating stellar models of TOI-849 are coupled to our orbital evolution code to study the evolution of the planetary orbit. The evolution of the planetary atmosphere is studied by means of the JADE code, which uses realistic X-ray and extreme-ultraviolet (XUV) fluxes provided by our rotating stellar models.
Results. Assuming that the planet was at its present-day position (ain = 0.01598 AU) at the protoplanetary disc dispersal, with mass 40.8 M⊕, and considering a broad range of host star initial surface rotation rates (Ωin ∈ [3.2, 18] Ω⊙), we find that only for Ωin ≤ 5 Ω⊙ do we reproduce the current position of the planet, given that for Ωin >  5 Ω⊙ its orbit is efficiently deflected by dynamical tides within the first ∼40 Myr of evolution. We also simulated the evolution of the orbit for values of ain ≠ 0.01598 AU for each of the considered rotational histories, confirming that the only combination suited to reproduce the current position of the planet is given by ain = 0.01598 AU and Ωin ≤ 5 Ω⊙. We tested the impact of increasing the initial mass of the planet on the efficiency of tides, finding that a higher initial mass (Min = 1 MJup) does not change the results reported above. Based on these results we computed the evolution of the planetary atmospheres with the JADE code for a large range of initial masses above a core mass of 40.8 M⊕, finding that the strong XUV-flux received by the planet is able to remove the entirety of the envelope within the first 50 Myr, even if it formed as a Jupiter-mass planet.
Theaflavin-3’-O-gallate a Black-tea Constituent Blocked SARS
CoV-2 RNA dependant RNA Polymerase Active-site with Better Docking Results than
Remdesivir
Authors: Banerjee Amrita , Kanwar Mehak , Maiti Smarajit 
Published: September 2021

Abstract
Background Replication of SARS-CoV-2 depends on viral RNA-dependent
RNA-polymerase (RdRp). Remdesivir, the broad-spectrum RdRp inhibitor acts as
nucleoside-analogues (NAs). Remdesivir has initially been repurposed as a
promising drug against SARS-CoV-2 infection with some health hazards like liver
damage, allergic reaction, low blood-pressure, and breathing-shortness,
throat-swelling. In comparison, theaflavin-3’-O-gallate (TFMG),
the abundant black tea component has gained importance in controlling viral
infection. TFMG is a non-toxic, non-invasive, antioxidant, anticancer and
antiviral molecule.
Results Here, we analyzed the inhibitory effect of
theaflavin-3’-O-gallate on SARS CoV-2 RdRp in comparison with
remdesivir by molecular-docking study. TFMG has been shown more potent in terms
of lower Atomic-Contact-Energy (ACE) and higher occupancy of surface area;
−393.97 Kcal/mol and 771.90 respectively, favoured with lower
desolvation-energy; −9.2 Kcal/mol. TFMG forms
more rigid electrostatic and H-bond than remdesivir. TFMG showed strong affinity
to RNA primer and template and RNA passage-site of RdRp.
Conclusions TFMG can block the catalytic residue, NTP entry site, cation
binding site, nsp7-nsp12 junction with binding energy of −6. 72
Kcal/mol with Ki value of 11.79, and interface domain with binding
energy of −7.72 and −6.16 Kcal/mol with Ki value of 2.21
and 30.71 µM. And most importantly, TFMG shows
antioxidant/anti-inflammatory/antiviral effect on human
studies.
Sexual Disorders in Women with Overactive Bladder and Urinary Stress Incontinence Compared to Controls: A Prospective Study

Published: September 2021

AbstractIntroduction and Hypothesis Female urinary incontinence (UI) has a negative impact on sexual function and sexual quality of life (QoL) in women. But there is still no consensus on the type of UI or the prevalence of sexual dysfunction (SD). The aim of the study was to evaluate sexual disorders in women with overactive bladder (OAB) compared to patients with urinary stress incontinence (SUI) and healthy controls.Materials and Methods 106 women presenting to a urogynecological outpatient clinic (referral clinic) were investigated using standardized questionnaires and the Female Sexual Function Index (FSFI-d). All 65 incontinent women underwent a full urodynamic examination; the controls (31) were non-incontinent women in the same age range who came for routine check-ups or minor disorders not involving micturition or pelvic floor function. Women with mixed urinary incontinence, a history of previous medical or surgical treatment for UI, recurrent urinary tract infections, previous radiation therapy or pelvic organ prolapse of more than stage 2 on the Pelvic Organ Prolapse Quantification (POP-Q) system were excluded.Results 100 questionnaires could be evaluated (94.3%). Thirty-four women had urinary stress incontinence, 35 had OAB, 31 were controls. Mean age was 56 years, with no significant differences between groups. The scores of the questionnaire ranged from 2 to 35.1 points. The median score of OAB patients was significantly lower (17.6) than the median score of the controls (26.5; p = 0,004). The stress-incontinent women had a score of 21.95, which was lower than that of the controls but statistically non-significant (p = 0.051). In all subdomains, the OAB patients had lower scores than the stress-incontinent women and significantly lower values than the control group. Most striking was the impairment of “sexual interest in the last 4 weeks”. The figure for “none or almost no sexual activity” was 80% for the OAB group, 64.7% for the group of stress-incontinent women and 48% for the control group. Incontinence during intercourse was reported by one OAB patient and 4 stress-incontinent women but did not occur in the control group.Conclusions There is a high prevalence of SD in women with urinary incontinence. Patients with OAB reported a greater negative impact on sexual function and had significantly lower scores for the FSFI questionnaire than patients with stress incontinence or controls.

AbstractThe clinical characteristics of patients with postoperative hypoparathyroidism who recover parathyroid function more than 12 months after surgery have not been studied. We aimed to evaluate whether the intensity of replacement therapy with calcium and calcitriol is related to the late recovery of parathyroid function. We compared the demographic, surgical, pathological, and analytical features of two groups of patients: cases, i. e., late recovery patients (those who recover parathyroid function>1 year after thyroidectomy, n=40), and controls, i. e., patients with permanent hypoparathyroidism (n=260). Replacement therapy with calcium and calcitriol was evaluated at discharge of surgery, 3–6 months, 12 months, and last visit. No significant differences were found in clinical, surgical, pathological, or analytical characteristics between cases and controls. The proportion of cases who required treatment with calcium plus calcitriol at 12 months was significantly lower than that found in controls (p<0.001). Furthermore, daily calcium and calcitriol doses in controls were significantly higher than those in cases at 3–6 months (p=0.014 and p=0.004, respectively) and at 12 months (p<0.001 and p=0.043, respectively). In several models of logistic regression analysis therapy with calcium and calcitriol at 12 months was negatively related to late recovery of parathyroid function. Although delayed recuperation of parathyroid function after total thyroidectomy is uncommon (13%), follow-up beyond 12 months is necessary in patients with postoperative hypoparathyroidism, especially in those whose needs of treatment with Ca and calcitriol are reducing over time.
Enantioselective Transfer Hydrogenation of Oxocarbenium Ions Enables Asymmetric Access to α-Substituted 1,3-Dihydroisobenzofurans
Authors: Liu Xigong , Liu Lei , Zhou Likai , Jia Kuiyong 
Published: September 2021

AbstractReported here is an efficient enantioselective transfer hydrogenation of cyclic oxocarbenium ions generated in situ through collapse of the corresponding acetal substrates. The asymmetric approach provides straightforward access to a variety of chiral α-aryl substituted 1,3-dihydroisobenzofurans in high yields with excellent enantioselectivities. α-Alkynyl substituted 1,3-dihydroisobenzofurans were also proved to be suitable substrates. In addition, when the reaction was performed at gram scale, the desired product was obtained in good yields with excellent enantioselectivity.
Transmediatisation of the Covid-19 crisis in Brazil: The emergence of (bio-/geo-)political repertoires of (re-)interpretation
Authors: de Souza Júnior Jaime 
Published: September 2021

AbstractThis paper focuses on the centrality of media practices to discuss in a transdisciplinary way how the Covid-19 crisis has been framed and communicated in Brazil across different media spaces, whereas the country became the second in the world with most deaths due to the spread of the Covid-19 infection. This discussion mobilises Foucauldian genealogical and critical discursive perspectives (Foucault, [1970]1981, p. 73) to create intelligibility about how domains of media power-knowledge, such as professional journalism and social media, generate textual trajectories, discursive-semiotic and epistemic disputes through (re-)framings. Based on oligoptic decisions (Latour, 2005, p. 182; Souza Júnior, 2020, pp. 59–64), the article explores a multimodal corpus of transmedia texts. 11 posts have been selected for discussion, since they pave the way for tracing a set of interconnected and (in-)visible elements about the corona crisis. In turn, this paper seeks to: (i) give visibility and qualitatively discuss some of the perspectives that have circulated across media spaces along with their related repertoires of biopolitical and geopolitical (re-)interpretation and (ii) expose the dynamics of power and resistance that emerge through pandemic frames, and how the latter communicate a social event like the Covid-19 crisis.
Gauge freedom in magnetostatics and the effect on helicity in toroidal volumes
Authors: Pfefferlé David , Noakes Lyle , Perrella David 
Published: September 2021

Magnetostatics defines a class of boundary value problems in which the topology of the domain plays a subtle role. For example, representability of a divergence-free field as the curl of a vector potential comes about because of homological considerations. With this in mind, we study gauge freedom in magnetostatics and its effect on the comparison between magnetic configurations through key quantities such as the magnetic helicity. For this, we apply the Hodge decomposition of k-forms on compact orientable Riemaniann manifolds with smooth boundary, as well as de Rham cohomology, to the representation of magnetic fields through potential one-forms in toroidal volumes. An advantage of the homological approach is the recovery of classical results without explicit coordinates and assumptions about the fields on the exterior of the domain. In particular, a detailed construction of minimal gauges and a formal proof of relative helicity formulas are presented.
Full spectrum 2D IR spectroscopy reveals below-gap absorption and phonon dynamics in the mid-IR bandgap semiconductor InAs
Authors: Stingel Ashley M. , Petersen Poul B. 
Published: September 2021

While the mid-infrared spectral region spans more than 3000 cm−1, ultrafast mid-IR spectroscopies are normally limited to the spectral bandwidth that can be generated in optical parametric amplifiers—typically a few hundred cm−1. As such, the spectral coverage in conventional two dimensional infrared (2D IR) spectroscopy captures only about 1% of the full potential 2D mid-IR spectrum. Here, we present 2D IR spectra using a continuum source as both the excitation and probe pulses, thus capturing close to the full 2D IR spectrum. While the continuum pulses span the entire mid-IR range, they are currently too weak to efficiently excite molecular vibrational modes but strong enough to induce electronic responses and excite phonons in semiconductors. We demonstrate the full spectrum 2D IR spectroscopy of the mid-IR bandgap semiconductor indium arsenide with a bandgap at 2855 cm−1. The measured response extends far below the bandgap and is due to field-induced band-shifting, causing probe absorption below the bandgap. While the band-shifting induces an instantaneous response that exists only during pulse overlap, the 2D IR spectra reveal additional off-diagonal features that decay on longer timescales. These longer-lived off-diagonal features result from coherent phonons excited via a Raman-like process at specific excitation frequencies. This study illustrates that the full spectrum 2D IR spectroscopy of electronic states in the mid-IR is possible with current continuum pulse technology and is effective in characterizing semiconductor properties.
Millikelvin scanning tunneling microscope at 20/22 T with a graphite enabled stick–slip approach and an energy resolution below 8 μeV: Application to conductance quantization at 20 T in single atom point contacts of Al and Au and to the charge density wave of 2H–NbSe2

We describe a scanning tunneling microscope (STM) that operates at magnetic fields up to 22 T and temperatures down to 80 mK. We discuss the design of the STM head, with an improved coarse approach, the vibration isolation system, and efforts to improve the energy resolution using compact filters for multiple lines. We measure the superconducting gap and Josephson effect in aluminum and show that we can resolve features in the density of states as small as 8 μeV. We measure the quantization of conductance in atomic size contacts and make atomic resolution and density of states images in the layered material 2H–NbSe2. The latter experiments are performed by continuously operating the STM at magnetic fields of 20 T in periods of several days without interruption.

Main text
This report gives the result of a bilateral comparison of resistance between the NSAI-NML (Ireland) and the BIPM carried out from November 2020 to March 2021. Two 1 Ω and two 10 kΩ travelling standards belonging to the BIPM were used. The comparison was carried out with an 'A-B-A' pattern of measurements; the standards were measured first at the BIPM for a period of about one month, then for a period of about one month at the NSAI-NML, and finally again at the BIPM. The measurand was the 4 terminal dc resistance at low power. The BIPM was the pilot laboratory, and the comparison forms part of the ongoing BIPM key comparisons BIPM.EM-K13.a (for 1 Ω) and BIPM.EM-K13b (for 10 kΩ).
The results from the NSAI-NML and the BIPM were found to be in good agreement, with a difference D smaller than the relative expanded uncertainty U
c (95% confidence, k = 2) giving D = - 0.081 × 10-6, U
c = 0.180 × 10-6 for 1 Ω and D = 0.069 × 10-6, U
c = 0.424 × 10-6 for 10 kΩ.

Abstract
We report on the development and extensive characterization of co-sputtered tantala–zirconia (Ta2O5-ZrO2) thin films, with the goal to decrease coating Brownian noise in present and future gravitational-wave detectors. We tested a variety of sputtering processes of different energies and deposition rates, and we considered the effect of different values of cation ratio η = Zr/(Zr + Ta) and of post-deposition heat treatment temperature T
a on the optical and mechanical properties of the films. Co-sputtered zirconia proved to be an efficient way to frustrate crystallization in tantala thin films, allowing for a substantial increase of the maximum annealing temperature and hence for a decrease of coating mechanical loss φ
c. The lowest average coating loss was observed for an ion-beam sputtered sample with η = 0.485 ± 0.004 annealed at 800 °C, yielding

rad. All coating samples showed cracks after annealing. Although in principle our measurements are sensitive to such defects, we found no evidence that our results were affected. The issue could be solved, at least for ion-beam sputtered coatings, by decreasing heating and cooling rates down to 7 °C h−1. While we observed as little optical absorption as in the coatings of current gravitational-wave interferometers (0.5 parts per million), further development will be needed to decrease light scattering and avoid the formation of defects upon annealing.
An augmented reality approach to learning about the force of gravity

Published: September 2021

Abstract
The experimental investigation of Newton’s law of universal gravitation requires expensive and sensitive equipment. Therefore, it is often not possible to conduct such an experiment within a typical physics class. An alternative is to investigate the universal gravitation law by using simulations. In this paper, we are presenting such an augmented reality simulation (GravityAR). The simulation has been developed for mobile devices and runs on an Android operating system, making it very accessible for students and teachers at all educational levels. It allows the user to investigate how the gravitational force between two spherical bodies depends on their masses and mutual distance. Additionally, the simulation can be used to determine the value of the gravitational constant (G).
