Published: November 2020

AbstractPupil dilation is known to be affected by a variety of factors, including physical (e.g., light) and cognitive sources of influence (e.g., mental load due to working memory demands, stimulus/response competition etc.). In the present experiment, we tested the extent to which vocal demands (speaking) can affect pupil dilation. Based on corresponding preliminary evidence found in a reanalysis of an existing data set from our lab, we setup a new experiment that systematically investigated vocal response‐related effects compared to mere jaw/lip movement and button press responses. Conditions changed on a trial‐by‐trial basis while participants were instructed to keep fixating a central cross on a screen throughout. In line with our prediction (and previous observation), speaking caused the pupils to dilate strongest, followed by nonvocal movements and finally a baseline condition without any vocal or muscular demands. An additional analysis of blink rates showed no difference in blink frequency between vocal and baseline conditions, but different blink dynamics. Finally, simultaneously recorded electromyographic activity showed that muscle activity may contribute to some (but not all) aspects of the observed effects on pupil size. The results are discussed in the context of other recent research indicating effects of perceived (instead of executed) vocal action on pupil dynamics.

Published: November 2020

AbstractEmotion regulation is a multi‐modal construct, that includes both adaptive and maladaptive cognitive‐behavioral processes. However, many classifications of regulation strategies do not take this multi‐modality into account. In this study, two classification systems were integrated. Participants were 336 adolescents (56% boys, Mage = 15.41, SD = 1.45). Anger regulation strategies were measured with a questionnaire that assessed general strategies, and a vignette measure that assessed contextual strategies. Confirmatory factor analyses supported a 4‐factor classification that consisted of cognitive maladaptive, behavioral maladaptive, cognitive adaptive, and behavioral adaptive strategies. The four categories of regulation strategies were differentially associated with age, and gender and psychological problem differences were found. Adolescents with internalizing problems reported using a cognitive regulation style, adolescents with externalizing problems a behavioral regulation style, and adolescents with comorbid internalizing and externalizing problems a maladaptive regulation style. These findings highlight the multi‐modal nature of emotion regulation and may provide opportunities for treatment modifications.

Abstract
Single-phase liquid cooling in microchannels and microgaps has been successfully demonstrated for heat fluxes of ∼1 kW/cm2 for silicon chips with maximum temperature below 100 °C. However, effectively managing localized hotspots in heterogeneous integration, which refers to the integration of various components that achieve multiple functionalities, entails further thermal challenges. To address these, we use a nonuniform pin-fin array. Single phase liquid-cooling performance of four silicon test chips, thermal design vehicles (TDVs), each with a nonuniform pin-fin array, are experimentally examined. We evaluate multiple combinations of hotspot and background heat fluxes using four background heaters aligned upstream to downstream, and one additional hotspot heater located in the center. We examine the thermal performance of cylindrical fin-enhanced TDVs and hydrofoil fin-enhanced TDVs, both with two designs: one with increased fin density around the hotspot only, and another with increased fin density spanning the entire width of the channel. The resulting heat flux ratio of the localized hotspot to background heaters varies from 1 to 5. TDVs with spanwise increased hydrofoil fin density (spanwise hydrofoil) exhibit the best thermal performance with 6% to 14% lower hotspot temperature than others. TDVs with spanwise increased cylindrical fin (cylindrical spanwise) maintain a balance between hotspot cooling performance and pressure drops. In general, as the temperature of the hotspot remains around 70 °C with a heat flux of 625 W/cm2, the nonuniform fin-enhanced microgaps appears to be a promising hotspot thermal management approach. The pressure drop of hydrofoil spanwise chip is highest among all the cases.
Rewetting Analysis of a Pressurized Water Reactor Fuel Slab Using Improved Lumped Models
Authors: Pereira Gustavo D. , Su Jian 
Published: November 2020

Abstract
This work analyzes the rewetting of a pressurized water reactor (PWR) fuel slab using improved lumped parameter formulations based on Hermite approximations for integrals. The time-dependent two-dimensional rewetting problem is transformed into a quasi-steady heat conduction problem in a reference system moving with the rewetting front by assuming a constant rewetting velocity. The lumped parameter formulations are applied in the slab thickness direction, reducing the two-dimensional problem into a one-dimensional heat conduction equation in the longitudinal direction. The rewetting velocity is obtained by combining the analytical solutions of the average temperature distributions in the reflooded wet region and the liquid deficient dry region at the rewetting front. The Peclet number is obtained as a function of the Biot numbers, dimensionless internal heat generation rate, and dimensionless initial temperatures. The obtained solutions compare favorably with available solutions in the literature.

Authors: Vogrin Matjaž , Kalc Miloš , Ličen Teja 
Published: November 2020

Context: It has been recently demonstrated that tissue flossing around the ankle joint can be effectively used to improve ankle range of motion, jump, and sprint ability. However, there is a lack of studies investigating the acute effects of tissue flossing applied using different wrapping pressures. Objective: To investigate the acute effects of tissue flossing and the degree of floss band pressure, around the upper thigh on knee range of motion, strength, and muscle contractile characteristics. Design: Crossover design in 3 distinct sessions. Setting: University laboratory. Participants: A total of 19 recreationally trained volunteers (age 23.8[4.8] y) participated in this study. Intervention: Active knee extension and flexion performed for 3 sets of 2 minutes (2-min rest between sets with wrapped upper thigh). Individualized wrapping pressures were applied to create conditions of high and moderate vascular occlusion, while a loose band application served as a control condition. Main Outcome Measures: Participants were assessed for active straight leg raise test; tensiomyography displacement and contraction time for rectus femoris, vastus medialis, and biceps femoris muscles; and maximum voluntary contractions for knee extensors and flexors for pre, after, and 30 minutes after applying the floss band. Results: There was a statistically significant increase in maximum voluntary contractions for knee extensors and a significant shortening in rectus femoris contraction time for the moderate condition, which was associated with small to medium effects in favor of the moderate condition. There were no statistically significant changes observed between control and high conditions. The active straight leg raise test was unaffected regardless of intervention. Conclusions: The results of this study suggest that tissue flossing around the upper thigh might have a localized as well as pressure-sensitive response, thereby improving neuromuscular function of the knee extensors.
Controls on eroded rock volume, a proxy for river incision, in Africa
Authors: Paul Jonathan D. 
Published: November 2020

AbstractA database of 3023 river basins in Africa was assembled to investigate the relative effects of uplift and erosion on landscape development. The volume of rock eroded from each basin was calculated by integrating the difference between a topographic summit envelope fit across drainage divides and interfluves, and present-day topography over basin area. Africa is an excellent natural laboratory for this procedure because drainage patterns reflect the Neogene development of topographic basins and swells, themselves surficial manifestations of sub-lithospheric mantle convection. As a result, the loci of major offshore deltas and drainage divides have remained largely static, while epeirogenic (vertical) surface motions are more important than shortening. Eroded rock volume is presented as a proxy for fluvial incision and correlates strongly with long-wavelength gravity anomalies across Africa, but not with mean precipitation, which was calculated by merging satellite estimates with rain gauge data. This finding implies that spatial variations in epeirogenic uplift govern landscape evolution across the continent. Other variables that alter drainage basin geometry and the magnitude of eroded rock volumes, such as varying climate, bedrock erodibility, and drainage capture, are likely subordinate to these variations. First-order estimates of eroded rock volume onshore are potentially the most accurate indicator of offshore sedimentation because they implicitly include information pertaining to basin area and relief, which together control sediment load.

Abstract
Mechanical twins form by the simple shear of the crystal lattice during deformation. In order to test the potential of narrow twins in monazite to record the timing of their formation, we investigated a ca. 1700 Ma monazite grain (from the Sandmata Complex, Rajasthan, India) deformed at ca. 980 Ma, by electron backscattered diffraction (EBSD), transmission electron microscopy (TEM), and atom probe tomography (APT). APT 208Pb/232Th ages indicate that the twin was entirely reset by radiogenic Pb loss during its formation at conditions far below the monazite closure temperature. The results are consistent with a model where Pb is liberated during rupture of rare earth element–oxygen (REE-O) bonds in the large [REE]O9 polyhedra during twinning. Liberated Pb likely migrated along fast diffusion pathways such as crystal defects. The combination of a quantitative microstructural investigation and nanogeochronology provides a new approach for understanding the history of accessory phases.

ObjectiveTo identify interventions being used to manage attention-deficit/hyperactivity disorder (ADHD) in the UK.DesignA survey within the Sheffield Treatments for ADHD Research project. A convenience sample of participants in the UK who consented to join an observational cohort were asked closed questions about medication, behavioural change programmes and service use, and an open-ended question about what else they used.SettingA broad variety of non-National Health Service, non-treatment seeking settings throughout the UK, including local authority organisations, schools, ADHD and autism spectrum condition support groups and social media.ParticipantsFamilies of children aged 5–18 with carer reported ADHD and Conners Global Index (CGI) T scores of 55+.ResultsResponses from 175 families were analysed. The mean age of the children was 10.21 (2.44), and two-thirds (n=114) had additional diagnoses. The majority used medications to manage ADHD (n=120) and had participated in a parenting class (n=130). Just over a quarter (28%, n=49) did not use ADHD medications, and used sleep medications. Just under half had consulted psychologists (n=83), and 32 had participated in other talking therapies such as psychotherapy, counselling and cognitive–behavioural therapy. A few used aids such as reward charts or fiddle toys (n=17) and participated in activities (mostly physical) (n=14). A substantial minority (78/175) had used non-mainstream treatments, the most popular being homoeopathy (n=32), nutritional interventions (n=21) and bodywork such as massage or cranial osteopathy (n=9).ConclusionsFamilies reported use of a wide variety of treatments to help with management of their children with ADHD in addition to their use of mainstream treatments.

AbstractThe challenges faced in a comparison of measuring the detection efficiency of free-running InGaAs/InP single-photon avalanche detectors (InGaAs/InP SPAD) were studied by four European National Metrology Institutes (NMIs) meeting at a single laboratory. The main purpose of this study is to develop a trustable measurement technique and to provide a snapshot of the methods used by the four NMIs for measuring such photon-counting detectors at telecom wavelengths in order to establish proper procedures for characterising such devices. The detection efficiency measurements were performed using different experimental setups and reference standards with independent traceability chains at the wavelength of 1550 nm. A dedicated model to correct the dead time and dark count effects on the SPAD’s free-running counting process was developed, allowing the correct value of the photon rate impinging on the detector to be recovered from simple ratemeter measurements. The detection efficiency was measured for mean photon number per pulse between 0.01 and 2.4, corresponding to photon rates between approximately 1100 photon/s and 193,000 photon/s, respectively. We found that the measured values reported by the participants are all consistent within the stated uncertainties, proving the consistency of the measurement approach developed.
Neutralization of radionuclides

Published: November 2020

Three cases are reviewed of radioactive material with anomalous decay after ultrasound irradiation. In the pure element thorium-228 in distilled water, the radioactivity decreased faster after cavitation than the natural decay. The more complex molecule of Nickel Nitrate, made of radioactive nickel-63, in solution of nitric acid and distilled water was investigated before and after ultrasound irradiation. The X-rays produced by Bremsstrahlung of the electrons from the beta decay of Ni-63 were recorded and a 13% decrease of intensity was measured after 100 s of sonication. A decrease of nickel and an increase of other elements was detected by mass spectrometry in the sonicated sample. The Cobalt-57 decay was investigated by detecting the gamma and X-ray intensity from the Iron-57 resulting after its beta emission. In this third case too, an anomalous decay was observed after sonication. These three cases of anomalous behavior can be explained at the light of the Deformed Space–Time theory. It assumes that a suitable sudden variation of energy density can induce a local deformation of space–time, thus violating the Local Lorentz Invariance. This variation can be created by the ultrasounds in the matter, thus, allowing reactions that cannot occur in a flat (Minkowskian) space–time. The “neutralization” of a radionuclide occurs when it undergoes a DST transformation changing the radionuclide into non-radioactive nuclides.

Aim. To evaluate the effect of an inhibitor of sodium-glucose cotransporter 2 (SGLT-2 inhibitor, dapagliflozin) on glycemic variability in type 2 diabetes mellitus (T2D) under insulin glargine combined with oral hypoglycemic drugs, using a continuous glucose monitoring system (CGMS). Methods. This prospective, self-controlled, single-center clinical trial recruited 36 patients with T2D under combined insulin glargine and oral hypoglycemic drugs. General clinical data were collected. Fasting blood glucose (FBG), postprandial blood glucose (PBG), glycosylated hemoglobin (HbA1c), and C-peptide levels were assessed before and four weeks of dapagliflozin (10 mg per day) treatment. Blood glucose was monitored for 72 hours before and after treatment using CGMS. Results. After treatment with dapagliflozin, FBG decreased from

). CGMS data showed reduction of the 24 h MBG, MAGE, time-above-range (TAR, >10 mmol/L), high blood glucose index (HBGI), glucose management indicator (GMI), and incremental area under the curve of the glucose level more than 10 mmol/L (

AUC

), and fewer insulin doses were required after the treatment, without increasing in hypoglycemia and urinary tract infection. Further, a stratified analysis showed that patients with higher pretreatment HbA1c and waist-to-hip ratio (WHR) had greater improvement in glycemic control. Conclusion. Dapagliflozin may reduce blood glucose levels, ameliorate glycemic variability, and improve pancreatic beta-cell function in patients with T2D under insulin glargine combined with other oral hypoglycemic drugs, especially in those with poor glucose control and abdominal obesity.
Simple Diagnostic Tools May Guide Transcatheter Closure of Superior Sinus Venosus Defects Without Advanced Imaging Techniques
Authors: Sivakumar Kothandam , Qureshi Shakeel , Pavithran Sreeja , Vaidyanathan Sunitha , Rajendran Monica 
Published: November 2020

Background:
There is a recent interest in nonsurgical correction of superior sinus venosus defects. Patient selection is currently based on advanced imaging and printing technologies. Simple clinical tools to select patients will expand its applicability in developing countries.

Methods:
Defects caudally extending toward the oval fossa and right upper pulmonary veins draining beyond the cavoatrial junction on transesophageal echocardiography were excluded. Balloon interrogation of cavoatrial junction confirmed complete occlusion of the defect with unobstructed pulmonary venous drainage to left atrium. Single long covered stents or overlapping covered stents were used to exclude sinus venosus defects. Closure of left-to-right interatrial shunt without causing pulmonary vein occlusion was confirmed on follow-up imaging.

Results:
Forty-four patients selected after transesophageal echocardiography underwent balloon interrogation with monitoring of right upper pulmonary vein. Eighteen out of 44 patients were ineligible. Twenty-four eligible patients with closure of left-to-right interatrial shunt without pulmonary vein occlusion underwent covered stent exclusion using single long stents in 15 and overlapping stents in the rest, while 2 patients are awaiting the procedure. Four patients aged 6 to 16 years received stents that were 18 mm or larger. Three patients had stent embolization that required surgical correction in 2 but in the last patient was managed nonsurgically with an overlapping covered stent with good final outcomes. Procedure was successful in 22 patients. At a median follow-up of 20 months (range, 3–54 months), there were no adverse events. Follow-up imaging showed trivial left-to-right shunt in 4 and unobstructed pulmonary veins in all patients.

Conclusions:
Transesophageal echocardiography and balloon interrogation identified 60% of the patients with sinus venosus defects to be eligible for catheter closure. Overlapping stents are an alternative to custom-made long stents. Transesophageal echocardiography confirms procedural success on follow-up. Advanced imaging and printing technologies are not essential for successful outcomes and thus simple tests increase the feasibility in developing countries.
Impacts of Lockdown Policies on International Trade*

Published: November 2020

AbstractThe aim of this study is to quantify how lockdown policies implemented in response to the COVID-19 pandemic affected international trade in the first half of 2020. We examine monthly world trade data between January and June in both 2019 and 2020. Our findings can be summarized as follows. Stay-at-home orders did not have significant and robust effects on trade. Negative effects were found in only some industries, including those producing durable products and essential products. However, workplace closures had significant negative effects on trade, except for intra-Asian trade. These effects of workplace closures can be found in most industries.
International Relations’ Critical Turn in the Humanitarian Space: Opportunities for Christian Engagement
Authors: Moore Alana 
Published: November 2020

Abstract
International Relations scholars routinely credit Christian actors with helping to create the modern international humanitarian order by institutionalizing principles of care and assistance within global governance. As this humanitarian order has become more secularized, however, faith-based reflections have been sidelined in secular academic work on humanitarian issues. This article reflects on the opportunities for dialogue and mutual engagement following the critical turn in International Relations scholarship over recent years. It highlights the development of International Relations thinking on the normative dimensions of the international humanitarian order and shows how their critiques of a secular order have created a window for engagement with the intellectual resources of the Christian traditions. Developing meeting places for engaging on deeper questions of ontologies of practice provides an opportunity to pursue a richer vision of global humanitarian endeavours, to the benefit of all.
