Published: February 2021

AbstractExploring shifts in the climatic niches of introduced species can provide significant insight into the mechanisms underlying the invasion process and the associated impacts on biodiversity. We aim to test the phylogenetic signal hypothesis in native and introduced species in Europe by examining climatic niche similarity. We examined data from 134 ant species commonly found in western Europe; 130 were native species, and 4 were introduced species. We characterized their distribution patterns using species records from different databases, determined their phylogenetic relatedness, and tested for a phylogenetic signal in their optimal climatic niches. We then compared the introduced species’ climatic niches in Europe with their climatic niches in their native ranges and with the climatic niches of their closest relative species in Europe. We found a strong phylogenetic signal in the optimal climatic niches of the most common ant species in Europe; however, this signal was weak for the main climatic variables that affect the distributions of introduced versus native species. Also, introduced species occupied different climatic niches in Europe than in their native ranges; furthermore, their European climatic niches did not resemble those of their closest relative species in Europe. We further discovered that there was not much concordance between the climatic niches of introduced species in their native ranges and climatic conditions in Europe. Our findings suggest that phylogenetics do indeed constrain shifts in the climatic niches of native European ant species. However, introduced species would not face such constraints and seemed to occupy relatively empty climatic niches.
Differences in clinical and imaging characteristics between p16-positive non-smokers and p16-positive smokers or p16-negative patients in oropharyngeal carcinoma

AbstractThe eighth edition of the TNM classifies oropharyngeal squamous cell carcinomas (OSCCs) depending on p16 status. Some imaging features are reportedly associated more frequently with p16-positive (P16+) OSCC than p16-negative (p16−) OSCC. However, classical risk factors such as tobacco use were not specifically considered when assessing these imaging features. We aimed to evaluate whether P16+ OSCCs have different epidemiological, clinical, prognostic and imaging features depending on smoking status, and to compare P16+ and p16− groups. A retrospective study of data from 85 patients with P16+ OSCC (41 non-smokers, 44 smokers) and 36 with p16− OSCC from 2011 to 2020 was carried out, assessing epidemiological data, clinical aspects of the tumour and presence of adenopathy. Staging was assessed according to the seventh and eighth editions of the TNM. Compared with P16+ OSCC non-smokers, P16+ OSCC smokers had tumours that were less well-defined (36.6% vs 77.8%, p < 0.001), more ulcerated (85.4% vs 44.4%, p < 0.001) and more necrotic (53.7% vs 25%, p = 0.012). There was also less downstaging from N2 or N3 of the seventh edition of the TNM to N1 of the eighth edition for smokers than non-smokers (22.7% vs 43.9%, p = 0.042). Compared with p16− tumours, more P16+ tumours had well-defined contours (55.8% vs 22.2%, p = 0.001), were exophytic (89.6% vs 72.2%, p = 0.023), less necrotic (40.3% vs 80.6%, p < 0.001), less ulcerated (97.2% vs 66.2%, p = 0.006) and involved less muscle tissue (26.0% vs 47.2%, p = 0.027).P16+ OSCCs of smokers show clinical, imaging and prognostic differences with P16+ OSCCs of non-smokers.
Insufficient transparency of statistical reporting in preclinical research: a scoping review
Authors: Gosselin Romain-Daniel 
Published: February 2021

AbstractNon-transparent statistical reporting contributes to the reproducibility crisis in life sciences, despite guidelines and educational articles regularly published. Envisioning more effective measures for ensuring transparency requires the detailed monitoring of incomplete reporting in the literature. In this study, a systematic approach was used to sample 16 periodicals from the ISI Journal Citation Report database and to collect 233 preclinical articles (including both in vitro and animal research) from online journal content published in 2019. Statistical items related to the use of location tests were quantified. Results revealed that a large proportion of articles insufficiently describe tests (median 44.8%, IQR [33.3–62.5%], k = 16 journals), software (31%, IQR [22.3–39.6%]) or sample sizes (44.2%, IQR [35.7–55.4%]). The results further point at contradictory information as a component of poor reporting (18.3%, IQR [6.79–26.7%]). No detectable correlation was found between journal impact factor and the quality of statistical reporting of any studied item. The under-representation of open-source software (4.50% of articles) suggests that the provision of code should remain restricted to articles that use such packages. Since mounting evidence indicates that transparency is key for reproducible science, this work highlights the need for a more rigorous enforcement of existing guidelines.

Authors: Takano Kenichi , Kaizaki Aya , Kimura Ayami , Nomura Kazuaki , Yamazaki Norikazu , Shintani Tomoko , Himi Tetsuo 
Published: February 2021

Purpose
This study aims to describe the recommended equipment and procedures required for successful telefitting, based on our experience, document and evaluate patient satisfaction with telefitting, and assess its clinical usefulness and address the existing issues.

Method
Twenty (seven children and 13 adults) individuals who lived far from cochlear implant (CI) centers and who were Nucleus CI users underwent conventional face-to-face fitting and telefitting. We examined the participants' subjective satisfaction and cost and time saved with the telefitting experience.

Results
The telefitting sessions lasted for an average of 16 min. Majority of the participants responded positively to the telefitting experience. Eighty percent (16/20) of the participants were satisfied with the new procedure, and 85% of them agreed to use telefitting again.

Conclusions
The results of our feasibility study suggest that telefitting was well received by CI users and is a viable alternative to local MAPping, even in young children with CIs. Although there are some limitations in terms of adaptability, telefitting could be an effective means of delivering CI service to remote locations.
Comparative Effects of Picture Symbol With Paired Text and Text-Only Augmentative and Alternative Communication Representations on Communication From Children With Autism Spectrum Disorder
Authors: Holyfield Christine 
Published: February 2021

Purpose
Technology features that maximize communicative benefit while minimizing learning demands must be identified and prioritized to amplify the efficiency and effectiveness of augmentative and alternative communication (AAC) intervention. Picture symbols with paired text are a common representation feature in AAC systems for children with autism spectrum disorder (ASD) who are preliterate, yet little research about their comparative benefit exists.

Method
Four school-age children with ASD and limited speech who were preliterate participated in two single-subject studies. In one study, communication of high imageability words (e.g., nouns) on an AAC app during a book-reading activity was compared across two representation conditions: picture symbols with paired text and text only. In the second study, communication of low imageability words (e.g., verbs) was compared. Both studies had baseline, intervention, generalization, and maintenance phases.

Results
Prior to intervention, participants communicated across both representation conditions at low rates except two participants who were relatively successful using picture symbol with paired text representations of high imageability words. In response to intervention, all participants demonstrated increases in communication across representation conditions and maintained the increases. Participants demonstrated generalization in the text-only representation condition.

Conclusions
Children with ASD who were preliterate acquired communication at comparable rates regardless of whether an AAC app utilized picture symbol with paired text or text-only representation. Therefore, while larger scale research is needed, clinicians and technology developers could consider increasing the use of text in AAC representation given the inherent value associated with learning to recognize written words.

Telehealth for Dysphagia Across the Life Span: Using Contemporary Evidence and Expertise to Guide Clinical Practice During and After COVID-19
Authors: Malandraki Georgia A. , Arkenberg Rachel Hahn , Mitchell Samantha S. , Malandraki Jaime Bauer 
Published: February 2021

Purpose
Our aim was to critically review recent literature on the use of telehealth for dysphagia during the COVID-19 pandemic and enhance this information in order to provide evidence- and practice-based clinical guidance during and after the pandemic.

Method
We conducted a rapid systematized review to identify telehealth adaptations during COVID-19, according to peer-reviewed articles published from January to August 2020. Of the 40 articles identified, 11 met the inclusion criteria. Full-text reviews were completed by three raters, followed by qualitative synthesis of the results and description of practical recommendations for the use of telehealth for dysphagia.

Results
Seven articles were guidelines articles, three were editorials, and one was a narrative review. One article focused on telehealth and dysphagia during COVID-19. The remaining 10 mentioned telehealth in varying degrees while focusing on dysphagia management during the pandemic. No articles discussed pediatrics in depth. The most common procedure for which telehealth was recommended was the clinical swallowing assessment (8/11), followed by therapy (7/11). Six articles characterized telehealth as a second-tier service delivery option. Only one article included brief guidance on telehealth-specific factors, such as legal safeguards, safety, privacy, infrastructure, and facilitators.

Conclusions
Literature published during the pandemic on telehealth for dysphagia is extremely limited and guarded in endorsing telehealth as an equivalent service delivery model. We have presented prepandemic and emerging current evidence for the safety and reliability of dysphagia telemanagement, in combination with practical guidelines to facilitate the safe adoption of telehealth during and after the pandemic.
Improving Dimensional Change Card Sort Performance of Preschoolers With Developmental Language Disorder: Effects of Two Task Variations
Authors: Kapa Leah L. 
Published: February 2021

Purpose
This research note addresses whether task administration variations can improve Dimensional Change Card Sort (DCCS) performance in preschoolers with developmental language disorder (DLD).

Method
Participants included preschoolers with DLD who failed the standard DCCS, which is characterized by inability to switch from one card sorting rule to a new rule. After an approximately 2.5-month delay, participants were retested on the DCCS in one of three conditions: repeating standard administration, participants labeling relevant card dimensions, or briefly removing target cards before the switch.

Results
Children in both the labeling and target removal conditions scored significantly higher on the second administration relative to the first. However, comparing across conditions, participants in the target removal condition scored higher on the second DCCS compared to participants in the standard and labeling conditions, which did not differ from each other.

Conclusions
DCCS performance of preschoolers with DLD can be improved by changing task administration. The most effective change is increasing the salience of the switch to the new sorting rule, as opposed to directing children's attention via their own labeling behavior.
Multi-wavelength observations and modelling of a quiescent cloud LDN1512
Authors: Saajasto Mika , Juvela Mika , Lefèvre Charlène , Pagani Laurent , Ysard Nathalie 
Published: February 2021

Context. Light scattering at near-infrared (NIR) wavelengths has been used to study the optical properties of the interstellar dust grains, but these studies are limited by the assumptions on the strength of the radiation field. On the other hand, thermal dust emission can be used to constrain the properties of the radiation field, although this is hampered by uncertainty about the dust emissivity.
Aims. Combining light scattering and emission studies allows us to probe the properties of the dust grains in detail. We wish to study if current dust models allow us to model a molecular cloud simultaneously in the NIR and far-infrared (FIR) wavelengths and compare the results with observations. Our aim is to place constraints on the properties of the dust grains and the strength of the radiation field.
Methods. We present computations of dust emission and scattered light of a quiescent molecular cloud LDN1512. We use NIR observations covering the J, H, and KS bands, and FIR observations between 250 and 500 μm from the Herschel space telescope. We constructed radiative transfer models for LDN1512 that include an anisotropic radiation field and a three-dimensional cloud model.
Results. We are able to reproduce the observed FIR observations, with a radiation field derived from the DIRBE observations, with all of the tested dust models. However, with the same density distribution and the assumed radiation field, the models fail to reproduce the observed NIR scattering in all cases except for models that take into account dust evolution via coagulation and mantle formation. The intensity from the diffuse interstellar medium like, dust models can be increased to match the observed one by reducing the derived density, increasing the intensity of the background sky and the strength of the radiation field between factors from two to three. We find that the column densities derived from our radiative transfer modelling can differ by a factor of up to two, compared to the column densities derived from the observations with modified blackbody fits. The discrepancy in the column densities is likely caused because of a temperature difference between a modified blackbody fit and the real spectra. The difference between the fitted temperature and the true temperature could be as high as ΔT = +1.5 K.
Conclusions. We show that the observed dust emission can be reproduced with several different assumptions about the properties of the dust grains. However, in order to reproduce the observed scattered surface brightness, dust evolution must be taken into account.
Chemical compositions of five Planck cold clumps

Published: February 2021

Aims. Interstellar molecules form early in the evolutionary sequence of interstellar material that eventually forms stars and planets. To understand this evolutionary sequence, it is important to characterize the chemical composition of its first steps.
Methods. In this paper, we present the result of a 2 and 3 mm survey of five cold clumps identified by the Planck mission. We carried out a radiative transfer analysis on the detected lines in order to put some constraints on the physical conditions within the cores and on the molecular column densities. We also performed chemical models to reproduce the observed abundances in each source using the gas-grain model Nautilus.
Results. Twelve molecules were detected: H2CO, CS, SO, NO, HNO, HCO+, HCN, HNC, CN, CCH, CH3OH, and CO. Here, CCH is the only carbon chain we detected in two sources. Radiative transfer analyses of HCN, SO, CS, and CO were performed to constrain the physical conditions of each cloud with limited success. The sources have a density larger than 104 cm−3 and a temperature lower than 15 K. The derived species column densities are not very sensitive to the uncertainties in the physical conditions, within a factor of 2. The different sources seem to present significant chemical differences with species abundances spreading over one order of magnitude. The chemical composition of these clumps is poorer than the one of Taurus Molecular Cloud 1 Cyanopolyyne Peak (TMC-1 CP) cold core. Our chemical model reproduces the observational abundances and upper limits for 79–83% of the species in our sources. The ‘best’ times for our sources seem to be smaller than those of TMC-1, indicating that our sources may be less evolved and explaining the smaller abundances and the numerous non-detections. Also, CS and HCN are always overestimated by our models.
A Matter of Caution: Coagulation Parameters in COVID-19 Do Not Differ from Patients with Ruled-Out SARS-CoV-2 Infection in the Emergency Department

Published: February 2021

AbstractCOVID-19 (coronavirus disease 2019) patients often show excessive activation of coagulation, associated with increased risk of thrombosis. However, the diagnostic value of coagulation at initial clinical evaluation is not clear. We present an in-depth analysis of coagulation in patients presenting to the emergency department (ED) with suspected COVID-19. N = 58 patients with clinically suspected COVID-19 in the ED were enrolled. N = 17 subsequently tested positive using SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) polymerase chain reaction (PCR) swabs, while in n = 41 COVID-19 was ruled-out. We analyzed both standard and extended coagulation parameters, including thromboplastin time (INR), activated partial thromboplastin time (aPTT), antithrombin, plasminogen, plasminogen activator inhibitor-1 (PAI-1), D-dimers, and fibrinogen at admission, as well as α2-antiplasmin, activated protein C -resistance, factor V, lupus anticoagulant, protein C, protein S, and von Willebrand diagnostics. These data, as well as mortality and further laboratory parameters, were compared across groups based on COVID-19 diagnosis and severity of disease. In patients with COVID-19, we detected frequent clotting abnormalities, including D-dimers. The comparison cohort in the ED, however, showed similarly altered coagulation. Furthermore, parameters previously shown to distinguish between severe and moderate COVID-19 courses, such as platelets, plasminogen, fibrinogen, aPTT, INR, and antithrombin, as well as multiple nonroutine coagulation analytes showed no significant differences between patients with and without COVID-19 when presenting to the ED. At admission to the ED the prevalence of coagulopathy in patients with COVID-19 is high, yet comparable to the non-COVID-19 cohort presenting with respiratory symptoms. Nevertheless, coagulopathy might worsen during disease progression with the need of subsequent risk stratification.
Neutral polar hybrid perovskites of [(CH3)2SO][RE(HCOO)3] (RE = Lu and Y): Phase transitions driven by transformation of weak C–H⋯O interactions
Authors: Xiong Li-Hui , Zhao Tian-Meng , Wang Bing-Wu , Wang Zhe-Ming , Gao Song 
Published: February 2021

Two iso-structural hybrid perovskites of [(CH3)2SO][RE(HCOO)3] for RE3+ = Lu3+ and Y3+ are polar and possess neutral rare earth formate frameworks incorporating dimethyl sulfoxide locating in the framework cavities and coordinating to the RE3+ ions. The materials display reversible phase transitions at 172 K and 138 K for Lu and Y, respectively. The phase transitions are driven by the transformations of weak C–H⋯O interactions and the gradual twists of the constituents in low temperature, which control the order–disorder states of dimethyl sulfoxide and account for different anisotropic thermal expansion behaviors for the two phases and the characters of dielectric responses.
Language over time
Authors: Couper-Kuhlen Elizabeth 
Published: February 2021

Abstract
This paper demonstrates how the tools of Interactional Linguistics can be applied to the study of change in
language use. It examines the particle OKAY as used in everyday American English interaction at two different points in time, the
1960s and the 1990s/early 2000s. The focus is on the remarkable increase of OKAY as a response in epistemically driven sequences.
Three uses of epistemic OKAY are identified in the newer data, one of which is unattested in the older data: OKAY in response to
information that has no implications for the recipient’s agenda or expressed beliefs. This novel use of OKAY appears in the newer
data where OH would have occurred earlier, although OH is still attested with displays of affect such as surprise and empathy. The
study concludes by arguing for an examination of ‘possibility spaces’, the set of options for filling a given sequential slot in
conversational structure, at different points in time as a means for identifying changes in language use.

Abstract
The photoproduction of the bottomonium-like states

and

via

scattering is studied within an effective Lagrangian approach and the vector-meson-dominance model. The Regge model is employed to calculate the photoproduction of

states via the t-channel with

exchange. The numerical results show that the values of the total cross-sections of

and

can reach 0.09 nb and 0.02 nb, respectively, near the center-of-mass energy of 22 GeV. Experimental measurements and studies of the photoproduction of

states near the energy region around

GeV are suggested. Moreover, with the help of eSTARlight and STARlight programs, we have obtained the cross-sections and numbers of events for

production in electron-ion collisions (EIC) and ultraperipheral collisions (UPCs). The results show that a considerable number of

events can be produced in the relevant experiments on EICs and UPCs. We have also calculated the rates and kinematic distributions for

in

and

collisions via EICs and UPCs. The results will provide an important reference for the RHIC, LHC, EIC-US, LHeC, and FCC experiments in searching for bottomonium-like

states.
Current status of an optically-segmented single-volume scatter camera for neutron imaging
Authors: Tellez-Galindo A. 
Published: February 2021

Abstract
The Single-Volume Scatter Camera (SVSC) approach to kinematic neutron imaging, in which an incident neutron’s direction is reconstructed via multiple neutron-proton scattering events, potentially offers much greater efficiency and portability than current systems. In our first design of an Optically-Segmented (OS) SVSC, the detector consists of an 8 × 8 array of 5 × 5 × 200 mm3 bars of EJ-204 scintillator wrapped in Teflon tape, optically coupled with SensL J-series 6 × 6 mm Silicon Photomultiplier (SiPM) arrays, all inside an aluminum frame that serves as a dark box. The SiPMs are read out using custom (multi-GSPS) waveform sampling electronics. In this work, construction, characterization, and electronics updates are reported. The position, time, and energy resolutions of individual bars were obtained by measuring different scintillators with different reflectors. This work was carried out in parallel at the University of Hawaii and at Sandia National Laboratories and resulted in the preliminary design of the camera. Monte-Carlo simulations using the Geant4 toolkit were carried out for individual scintillator bars, as well as the array setup. A custom analysis using ROOT libraries in C++ simulated the SiPM response from Geant4 photon hits. This analysis framework is under development and will allow for seamless comparisons between experimental and simulated data.
