AbstractIsolation, contact tracing and restrictions on social movement are being globally implemented to prevent and control onward spread of SARS-CoV-2, even though the infection risk modelled on RNA detection by RT-qPCR remains biased as viral shedding and infectivity are not discerned. Thus, we aimed to develop a rapid viability RT-qPCR procedure to infer SARS-CoV-2 infectivity in clinical specimens and environmental samples. We screened monoazide dyes and platinum compounds as viability molecular markers on five SARS-CoV-2 RNA targets. A platinum chloride-based viability RT-qPCR was then optimized using genomic RNA, and inactivated SARS-CoV-2 particles inoculated in buffer, stool, and urine. Our results were finally validated in nasopharyngeal swabs from persons who tested positive for COVID-19 and in wastewater samples positive for SARS-CoV-2 RNA. We established a rapid viability RT-qPCR that selectively detects potentially infectious SARS-CoV-2 particles in complex matrices. In particular, the confirmed positivity of nasopharyngeal swabs following the viability procedure suggests their potential infectivity, while the complete prevention of amplification in wastewater indicated either non-infectious particles or free RNA. The viability RT-qPCR approach provides a more accurate ascertainment of the infectious viruses detection and it may complement analyses to foster risk-based investigations for the prevention and control of new or re-occurring outbreaks with a broad application spectrum.

AbstractWe develop an algorithmic framework for contracting tensor networks and demonstrate its power by classically simulating quantum computation of sizes previously deemed out of reach. Our main contribution, index slicing, is a method that efficiently parallelizes the contraction by breaking it down into much smaller and identically structured subtasks, which can then be executed in parallel without dependencies. We benchmark our algorithm on a class of random quantum circuits, achieving greater than 105 times acceleration over the original estimate of the simulation cost. We then demonstrate applications of the simulation framework for aiding the development of quantum algorithms and quantum error correction. As tensor networks are widely used in computational science, our simulation framework may find further applications.

Purpose
This project sought to develop consensus guidelines for clinically meaningful, comprehensive assessment procedures for people who stutter across the lifespan.

Method
Twelve expert clinicians and researchers who have written extensively about stuttering provided detailed descriptions of the type of data that they routinely collect during diagnostic evaluations of preschool children, school-age children, adolescents, and adults who stutter. Iterative content analysis, with repeated input from the respondents, was used to identify core areas that reflect common domains that these experts judge to be important for evaluating stuttering for varying age groups.

Results
Six core areas were identified as common components of a comprehensive evaluation of stuttering and people who stutter. These areas should be included to varying degrees depending upon the age and needs of the client or family. The core areas include the following: (a) stuttering-related background information; (b) speech, language, and temperament development (especially for younger clients); (c) speech fluency and stuttering behaviors; (d) reactions to stuttering by the speaker; (e) reactions to stuttering by people in the speaker's environment; and (f) adverse impact caused by stuttering.

Discussion
These consensus recommendations can help speech-language pathologists who are uncertain about appropriate stuttering assessment procedures to design and conduct more thorough evaluations, so that they will be better prepared to provide individualized and comprehensive treatment for people who stutter across the lifespan.
Orthographic Knowledge and Clue Word Facilitated Spelling in Children With Developmental Language Disorder
Authors: Williams Gareth J. , Larkin Rebecca F. , Rose Naomi V. , Whitaker Emily , Roeser Jens , Wood Clare 
Published: September 2021

Purpose
This study investigated the orthographic knowledge and how orthographic and phonological information could support children with developmental language disorder (DLD) to make more accurate spelling attempts.

Method

Children with DLD (
N
= 37) were matched with chronological age–matched (CAM) children and language age–matched children. These children completed specific and general orthographic knowledge tasks as well as spelling task conditions with either no clue word (pretest), a phonological clue word, or an orthographic clue word.

Results
Children with DLD were significantly less accurate in their specific orthographic knowledge, compared with CAM children, but had similar scores for general orthographic knowledge to CAM children. Children with DLD and both controls had significantly higher spelling scores in the orthographic clue word condition compared with a pretest pseudoword spelling task.

Conclusions
Children with DLD acquire the general knowledge of a written language's orthography but, possibly through less print exposure, have less well-represented word-specific orthographic knowledge. Moreover, children with DLD are able to extract the orthographic features of a clue word and employ these to produce more accurate spellings. These findings offer support for a spelling intervention approach based on orthography.
Situational Embarrassment and Its Relationship to Social Anxiety in Adults Who Stutter
Authors: Tran Yvonne , Blumgart Elaine , Craig Ashley 
Published: September 2021

Purpose
Adults who stutter (AWS) have increased risk of comorbid social anxiety about speaking in social contexts. AWS also report experiencing embarrassment in different social situations; however, research has rarely been conducted on embarrassment and its relationship to social anxiety in AWS.

Method

AWS (
N
= 200) reported their level of embarrassment on four 10-point Likert items when speaking in four situational contexts: at home, to an individual important to them, in social groups, and at work. Participants were also assessed for sociodemographic, stuttering, and anxiety variables. Construct validity for the four embarrassment items was examined, the extent of embarrassment established in the four contexts as a function of age and sex, and the relationship of embarrassment to social anxiety evaluated.

Results

Evidence of acceptable construct validity and reliability is presented for the four embarrassment Likert items. Sixty-five percent of the sample experienced high levels of embarrassment when speaking in groups or at work, while 35.5% experienced high levels when speaking at home or to an individual important to them. Participants were significantly more embarrassed (
p
< .01) when speaking at work or when socializing in groups. Embarrassment was lowest when speaking in the home. Younger females were significantly more embarrassed when speaking at work or when socializing in groups. Those with high embarrassment scores on all four items were more likely to have elevated social anxiety scores (
p
< .001).

Conclusion
These preliminary results suggest that the assessment of situational embarrassment could be an important clinical measure that may help improve stuttering treatment outcomes that also target social anxiety.

Published: September 2021

Purpose: This study aimed to evaluate whether there are any differences in outcomes and complication rates between condylar constrained knee (CCK) and rotating hinge knee (RHK) prostheses used for the first revision of total knee arthroplasty (rTKA) after mechanical failure. Methods: Sixty-three consecutive non-septic revisions of posterior stabilized implants using 33 CCK and 30 RHK prostheses were included. Clinical evaluation and revision rate were compared between the two groups at two years minimum follow-up. Results: The CCK group had significantly better clinical outcomes and satisfaction rates compared to patients with RHK (KSS-knee 70.5 versus 60.7 (p < 0.003) and KSS-function 74.9 versus 47.7 (p < 0.004) at 3.7 (2.0–9.4) years mean follow-up. Moreover, the clinical improvement was significantly higher for the CCK group concerning the KSS-Knee (+23.9 vs. +15.2 points, p = 0.03). The postoperative flexion was significantly better in the CCK group compared to the RHK group (115° vs. 103°, p = 0.01). The prosthesis-related complications and the re-revision rate were higher in the RHK group, especially due to patellofemoral complications and mechanical failures. Conclusions: CCK prostheses provided better clinical and functional outcomes and fewer complications than RHK prostheses when used for the first non-septic rTKA. CCK is a safe and effective implant for selected patients, while RHK should be used with caution as a salvage device for complex knee conditions, with particular attention to the balance of the extensor mechanism.

Zusammenfassung
Ziel der Studie Bei der Untersuchung von sozialer Ängstlichkeit
haben sich die Fragebögen Liebowitz Social Anxiety Scale (LSAS) und das
Social Phobia-Inventory (SPIN) etabliert. Außerdem wird zum Screening
sozialer Ängstlichkeit häufig die Subskala Unsicherheit im
Sozialkontakt des Brief Symptom Inventory (BSI-53) eingesetzt. Alle drei Skalen
geben vor dasselbe Konstrukt zu erfassen. Somit stellt sich die Frage der
Konvergenz dieser Skalen. Um Forschungsergebnisse zu sozialer
Ängstlichkeit, welche diese Instrumente nutzen, über einen
fragebogenübergreifenden Faktor (Common-Faktor) vergleichbar zu machen,
wird in der vorliegenden Studie ein Item Response Theorie (IRT) Linking Ansatz
verwendet.
Methodik 64 deutschsprachige psychiatrische Patienten und 295 Probanden
aus der deutschen Normalbevölkerung füllten die drei
Fragebögen aus. Verschiedene IRT-Modelle – darunter Graded
Response Modelle (GRM) – wurden an die Daten angepasst und verglichen.
Basierend auf dem Modell mit dem besten Fit wurden Regressionsanalysen
durchgeführt. Der Common-Faktor wurde dabei jeweils von den
Fragebogensummenwerten vorhergesagt.
Ergebnisse Der Zusammenhang zwischen den verschiedenen Skalen wird am
besten durch ein Bi-Faktor GRM erklärt (RMSEA=0,036;
CFI=0,977; WRMR=1,061). Anhand der Ergebnisse der
Regressionsanalysen lassen sich drei Gleichungen zur Transformation von
Fragebogensummenwerten ableiten.
Schlussfolgerung Durch den IRT Linking Ansatz konnte ein
fragebogenübergreifender genereller Faktor Sozialer
Ängstlichkeit abgeleitet werden. Gemeinsamkeiten und Unterschiede wurden
dabei berücksichtigt. Dies hat sowohl für die Forschung als auch
für die Praxis Vorteile. Eine Replikation dieser Studie sowie die
Implementierung weiterer Instrumente wird empfohlen, um die Gültigkeit
dieses Ansatzes zu überprüfen und die Ergebnisse zu
generalisieren.
Clinical Significance of Coexistence of Hashimoto Thyroiditis and Graves’ Disease with Differentiated and Medullary Thyroid Cancer
Authors: Machens Andreas , Lorenz Kerstin , Weber Frank , Dralle Henning 
Published: September 2021

AbstractThe association of Hashimoto thyroiditis and Graves’ disease with papillary, follicular, and medullary thyroid cancer has not been comprehensively investigated until now. This comparative clinicopathological study of consecutive patients thyroidectomized at a surgical referral center aimed to explore interdependencies between chronic autoimmune thyroiditis and thyroid cancer. Altogether, there were 852 (58.4%) patients with papillary thyroid cancer, 181 (12.4%) patients with follicular thyroid cancer, and 426 (29.2%) patients with sporadic medullary thyroid cancer, of whom 75 (5.1%) patients also had Hashimoto thyroiditis and 40 (2.7%) patients also had Graves’ disease. Patients with papillary (medians of 42 vs. 48 years; P =0.008) and follicular (medians of 33 vs. 63 years; P=0.022) thyroid cancer, unlike patients with medullary thyroid cancer (medians of 57.5 vs. 57 years; P=0.989), were younger at thyroidectomy when they had Hashimoto thyroiditis concomitantly. No such associations were seen with Graves’ disease. Primary thyroid cancers tended to be more localized in conjunction with Hashimoto thyroiditis, and less so with Graves’ disease, although patterns were not consistent across tumor types. In conclusion, Hashimoto thyroiditis, but not Graves’ disease, may be associated with differentiated (papillary and follicular) thyroid cancer but not with medullary thyroid cancer.
Unified Approach to ent-Eudesmane-Type Terpenoid Synthesis: Total Synthesis of Sinupol and Eutyscoparin A
Authors: Ota Koichiro , Miyaoka Hiroaki , Kamaike Kazuo 
Published: September 2021

Abstract
ent-Eudesmane-type terpenoids constitute a large class of natural products derived from plants, animals, and bacteria. We describe a synthetic approach to two ent-eudesmane-type terpenoids, sinupol and eutyscoparin A, that relies on a key π-facial- and endo/exo-selective intramolecular Diels–Alder reaction to set the C-5–C-10 stereotriads. Further key transformations of trans-fused decalin include conversion to methyl ketone via a versatile thioester intermediate and appropriate functionalization toward target compounds.
Use and effectiveness of policy briefs as a knowledge transfer tool: a scoping review
Authors: Arnautu Diana , Dagenais Christian 
Published: September 2021

AbstractThere is a significant gap between researchers’ production of evidence and its use by policymakers. Several knowledge transfer strategies have emerged in the past years to promote the use of research. One of those strategies is the policy brief; a short document synthesizing the results of one or multiple studies. This scoping study aims to identify the use and effectiveness of policy briefs as a knowledge transfer strategy. Twenty-two empirical articles were identified, spanning 35 countries. Results show that policy briefs are considered generally useful, credible and easy to understand. The type of audience is an essential component to consider when writing a policy brief. Introducing a policy brief sooner rather than later might have a bigger impact since it is more effective in creating a belief rather than changing one. The credibility of the policy brief’s author is also a factor taken into consideration by decision-makers. Further research needs to be done to evaluate the various forms of uses of policy briefs by decision-makers.
Uberization of translation
Authors: Fırat Gökhan 
Published: September 2021

Abstract
Digital labour platforms, encompassing on-demand translation work via apps and websites, have grown exponentially
in recent years and have significant consequences for translation workers. This study explores the critical literature on digital
labour platforms from a labour studies perspective and submits the findings of a quantitative survey of 70 translation workers
residing in Turkey and working on/for digital labour platforms. Our research suggests that the introduction of digital labour
platforms into translation production and business networks has not yet provided a significant contribution to the working
conditions of translation workers in Turkey. Instead, we argue that their working conditions have been rearranged and reorganized
in accordance with the uberization of (translation) work. According to the survey findings, engaging in such work on/for digital
labour platforms exposes translation workers to risks related to employment status, income level, work-life balance, social
protections, free agency, bargaining power, dependence on the platform, allocation of risks and rewards, and data collection,
protection and privacy.

Abstract
Finding new materials with antiferromagnetic (AFM) Kitaev interaction is an urgent issue for quantum magnetism research. We conclude that Na3Co2SbO6 and Na2Co2TeO6 are new honeycomb cobalt-based systems with AFM Kitaev interaction by carrying out inelastic neutron scattering experiments and subsequent analysis. The spin–orbit excitons observed at 20–28 meV in both compounds strongly support the idea that Co2+ ions of both compounds have a spin-orbital entangled J
eff = 1/2 state. Furthermore, we found that a generalized Kitaev–Heisenberg Hamiltonian can describe the spin-wave excitations of both compounds with additional 3rd nearest-neighbor interaction. Our best-fit parameters show significant AFM Kitaev terms and off-diagonal symmetric anisotropy terms of a similar magnitude in both compounds. We also found a strong magnon-damping effect at the higher energy part of the spin waves, entirely consistent with observations in other Kitaev magnets. Our work suggests Na3Co2SbO6 and Na2Co2TeO6 as rare examples of the AFM Kitaev magnets based on the systematic studies of the spin waves and analysis.

Abstract
Single-crystalline lead substituted M-type barium hexaferrites doped with different concentrations of Al3+, synthesized by flux technique are investigated at terahertz and infrared frequencies (8-8000 cm−1). The spectra of reflection coefficient (R), transmission coefficient (T), complex dielectric permittivity (ε` and ε``) were obtained using terahertz time-domain, and infrared Fourier transform spectrometers over a broadband frequency range 0.24-240 THz and at temperatures 5 K-300 K. The observed absorption lines are assigned to the electronic transitions within the fine-structured ground state of Fe2+ ions at terahertz frequencies and to optical phonon mode at far-infrared frequencies. To analyze the origin of terahertz excitations in the compounds, we provided a model that accounts for the second-order spin-orbit interactions, the triagonal distortion of the crystal field, and the selection rules of the (C3v) point group symmetry of tetrahedral site-position of Fe2+.

Abstract
Academics is a huge repository of research avenue. Students tend to behave and adapt to the classroom based on their peer influences. Peers help in the increase of communication skills. Research shows group study is more effective than individual study. Group formation is influenced by several factors, like friendships, demographically and linguistically similar. Toppers are more considerate but again based on comfort level friends are chosen. In this paper the changes in preferences of group mates are analyzed, and inferences are drawn over their reconciliations.
