An Area Theorem for Joint Harmonic Functions on the Product of Homogeneous Trees
Authors: Atanasi Laura , Picardello Massimo A. 
Published: September 2021

AbstractFor harmonic functions v on the disc, it has been known for a long time that non-tangential boundedness a.e.is equivalent to finiteness a.e. of the integral of the area function of v (Lusin area theorem). This result also hold for functions that are non-tangentially bounded only in a measurable subset of the boundary, and has been extended to rank-one hyperbolic spaces, and also to infinite trees (homogeneous or not). No equivalent of the Lusin area theorem is known on higher rank symmetric spaces, with the exception of the degenerate higher rank case given by the cartesian product of rank-one hyperbolic spaces. Indeed, for products of two discs, an area theorem for jointly harmonic functions was proved by M.P. and P. Malliavin, who introduced a new area function; non-tangential boundedness a.e. is a sufficient condition, but not necessary, for the finiteness of this area integral. Their result was later extended to general products of rank-one hyperbolic spaces by Korányi and Putz. Here we prove an area theorem for jointly harmonic functions on the product of a finite number of infinite homogeneous trees; for the sake of simplicity, we give the proofs for the product of two trees. This could be the first step to an area theorem for Bruhat–Tits affine buildings, thereby shedding light on the higher rank continuous set-up.
Vertical integration vs. specialization: a nonparametric conditional efficiency estimate for the global semiconductor industry
Authors: Qiao Guangshun , Wang Zhan-ao 
Published: September 2021

AbstractThis paper applies a two-stage nonparametric approach to compare companies operating in different business models in the global semiconductor industry. Using panel data over 1999–2018 on 470 companies in the global semiconductor industry, we explore the operating performance of the semiconductor companies conditional on capital investment and between the integrated device manufacturers and the fabless-foundry business model. We find that vertically integrated device manufacturers are constrained heavily by capital investment. Disentangling the effects of capital investment and business model by a second-stage nonparametric regression, this paper identifies that the vertically specialized fabless-foundry business model helps to improve pure efficiency and mitigate the impact of business-cycle in the global semiconductor industry.
Morphological processing in developmental handwriting production: evidence from kinematics
Authors: Hess Stefan , Mousikou Petroula , Schroeder Sascha 
Published: September 2021

AbstractIn this study, we investigated effects of morphological processing on handwriting production in beginning writers of German. Children from Grades 3 and 4 were asked to copy words from a computer screen onto a pen tablet, while we recorded their handwriting with high spatiotemporal resolution. Words involved a syllable-congruent visual disruption (e.g., “Golfer”), a morpheme-congruent visual disruption (e.g., “Golfer”), or had no disruption (e.g., “Golfer”). We analyzed productions in terms of Writing Onset Duration and Letter Duration at the onset of the second syllable (“f” in “Gol.fer”) and the onset of the suffix (“e” in “Golf_er”). Results showed that durations were longer at word-writing onset only for words with a morpheme-congruent visual disruption. Also, letter durations were longer at the onset of the second syllable (i.e., “-fer”) and shorter at the onset of the suffix (i.e., “-er”) only for words with a syllable-congruent visual disruption. We interpret these findings within extant theories of handwriting production and offer an explanation for the observed effects before and during trajectory formation.
A future for seafood point-of-origin testing using DNA and stable isotope signatures

Published: September 2021

AbstractDemand for seafood products is increasing worldwide, contributing to ever more complex supply chains and posing challenges to trace their origin and guarantee legal, well-managed, sustainable sources from confirmed locations. While DNA-based methods have proven to be reliable in verifying seafood authenticity at the species level, the verification of geographic origin remains inherently more complex. Both genetic and stable isotope analyses have been employed for determining point-of-origin with varying degrees of success, highlighting that their application can be effective when the right tool is selected for a given application. Developing an a priori prediction of their discrimination power for different applications can help avoid the financial cost of developing inappropriate reference datasets. Here, we reviewed the application of both techniques to seafood point-of-origin for 63 commercial finfish species certified by the Marine Stewardship Council, and showed that, even for those species where baseline data exist, real applications are scarce. To fill these gaps, we synthesised current knowledge on biological and biogeochemical mechanisms that underpin spatial variations in genetic and isotopic signatures. We describe which species’ biological and distribution traits are most helpful in predicting effectiveness of each tool. Building on this, we applied a mechanistic approach to predicting the potential for successful validation of origin to three case study fisheries, using combined genetic and isotopic methodologies to distinguish individuals from certified versus non-certified regions. Beyond ecolabelling applications, the framework we describe could be reproduced by governments and industries to select the most cost-effective techniques.

Significance of forms and foci of metacognitive regulation in collaborative science learning of less and more successful outcome groups in diverse contexts
Authors: Iiskala Tuike , Volet Simone , Jones Cheryl , Koretsky Milo , Vauras Marja 
Published: September 2021

AbstractThis study investigated how metacognitive regulation (MR), especially its forms and foci, was manifested in less and more successful outcome groups’ collaborative science learning in diverse learning contexts. Whilst previous research has shown that different forms and foci of MR exist in collaborative learning, their role in groups’ learning outcomes remains unexplored. Drawing conclusions from different studies has been difficult because these have used different conceptualisations and analytic methods. In the present study, the learning processes of less and more successful outcome groups from three diverse collaborative science learning contexts were scrutinised. The contexts differed in academic level, disciplinary subject, and national culture. The same theory-based conceptualisations, coding systems, coders, and analyses were used across contexts. In addition, the tasks studied were designed using the same guiding principles. Transcribed video and audio recordings of the groups’ verbal interactions for two distinct interaction segments from these tasks formed the basis of the analyses. Manifestation of forms and foci of MR were quantitatively and qualitatively illustrated in each context. The main findings show that the manifestation of MR of less and more successful outcome groups demonstrated similarities and differences in the three different learning contexts. This study contributes to a contextualised understanding of MR in collaborative science learning, and highlights the importance of using similar, rigorous analytical tools across diverse contexts.

Abstract
Purpose
To assess the percentage of computed tomography pulmonary angiography (CTPA) procedures that could have been avoided by methodical application of the Revised Geneva Score (RGS) coupled with age-adjusted D-dimer cut-offs rather than only clinical judgment in Emergency Department patients with suspected pulmonary embolism (PE).

Material and methods
Between November 2019 and May 2020, 437 patients with suspected PE based on symptoms and D-dimer test were included in this study. All patients underwent to CTPA. For each patient, we retrospectively calculated the age-adjusted D-dimer cut-offs and the RGS in the original version. Finally, CT images were retrospectively reviewed, and the presence of PE was recorded.

Results
In total, 43 (9.84%) CTPA could have been avoided by use of RGS coupled with age-adjusted D-dimer cut-offs. Prevalence of PE was 14.87%. From the analysis of 43 inappropriate CTPA, 24 (55.81%) of patients did not show any thoracic signs, two (4.65%) of patients had PE, and the remaining patients had alternative thoracic findings.

Conclusion
The study showed good prevalence of PE diagnoses in our department using only physician assessment, although 9.84% CTPA could have been avoided by methodical application of RGS coupled with age-adjusted D-dimer cut-offs.

Published: September 2021

AbstractOn June 24, 2021, a 40-year-old reinforced concrete flat plate structure building in Miami suffered a sudden partial collapse. This study analyzed the overall performance and key components of the collapsed building based on the building design codes (ACI-318 and GB 50010). Punching shear and post-punching performances of typical slab-column joints are also studied through the refined finite element analysis. The collapse process was simulated and visualized using a physics engine. By way of these analyses, weak design points of the collapsed building are highlighted. The differences between the reinforcement detailing of the collapsed building and the requirements of the current Chinese code are discussed, together with a comparison of the punching shear and post-punching performances. The simulated collapse procedure and debris distribution are compared with the actual collapse scenes.
An improved method of anchoring chest drain and suture technique for Uni-portal VATS incision
Authors: Sun Zhiyong , Zheng Jiajie , Cao Ziang , Zhao Xiaojing 
Published: September 2021

AbstractUni-portal video-assisted thoracoscopic approach is currently a popular surgical technique in general thoracic surgery. After operation, a chest tube is usually placed through the incision to drain the effusion and gas from the thoracic cavity. In the conventional method, the retaining stitches should be taken out ten days after removing chest drain. To get better would-healing and avoid unsightly scar, we explored a method of anchoring chest drain and two-layer suture for Uni-portal incision without removing stitches post operation.
Predicting physical activity change in cancer survivors: an application of the Health Action Process Approach
Authors: Hardcastle Sarah J. , Maxwell-Smith Chloe , Hagger Martin S. 
Published: September 2021

Abstract
Purpose
Previous research has not examined the utility of the Health Action Process Approach (HAPA) to predict physical activity (PA) change in cancer survivors. The aim of the study was to investigate the efficacy of a HAPA-based model in predicting temporal change in moderate-to-vigorous physical activity (MVPA) in cancer survivors.

Methods
Participants enrolled in the Wearable Activity Technology and Action Planning (WATAAP) trial completed validated questionnaires (n = 64) to assess HAPA constructs (action and maintenance self-efficacy, outcome expectancies, action planning, risk perceptions, and intention) and wore an ActiGraph to measure PA at baseline, 12 weeks, and 24 weeks later. Data were analyzed using variance-based structural equation modeling with residualized change scores for model variables.

Results
Consistent with predictions, changes in action self-efficacy (β = 0.490, p < 0.001, ES = 0.258) and risk perceptions (β = 0.312, p = 0.003, ES = 0.099) were statistically significant predictors of intention change over time. Changes in intention (β = 0.217, p = 0.029, ES = 0.040) and action planning (β = 0.234, p = 0.068, ES = 0.068) predicted changes in MVPA. Overall, the model accounted for significant variance in intention (R2 = 0.380) and MVPA (R2 = 0.228) change.

Conclusions
Changes in intention and action planning were important correlates of MVPA change over 24 weeks. Further, changes in action self-efficacy and risk perceptions predicted changes in intention. Implications for cancer survivors: interventions that foster risk perceptions and self-efficacy, strengthen intentions, and promote action planning may be effective in promoting sustained PA change in cancer survivors.
Upper extremity deep venous thrombosis prevalence in the NHS Grampian Medical Ambulatory clinic: diagnostic, therapeutic, and prognostic considerations in oncology patients
Authors: Kastora Stavroula Lila , Oduyoye Olusegun , Mahmood Shafaq 
Published: September 2021

Abstract
Introduction
Whilst upper extremity deep vein thromboses (UEDVT) account for approximately 5 to 10% of all cases of DVT, rigorous guidelines regarding diagnosis and management of presenting patients remain to be developed. The association of UEDVT with concurrent asymptomatic pulmonary embolism as well as the first presentation of malignancy deems essential rigorous research and clinical guideline development to ensure optimal patient care.

Methods
This retrospective audit study is the first to provide estimates of UEDVT prevalence in the North-East Deanery main hospital centre, Aberdeen Royal Infirmary (ARI).

Results
Of the 605 patients attending the ARI Ambulatory Emergency Care (AEC) clinic with clinical suspicion of UEDVT, 38 (6.2%) had a confirmatory diagnosis. Underlying malignancy, presence of PICC line, and cardiovascular co-morbidities were identified as common confounding factors. Subclavian vein with concurrent extension to primarily the cephalic vein thrombosis was identified as the most commonly thrombosed venous territories. Importantly, oncology patients were found to have poorer survival outcomes following an UEDVT, in comparison to patients with other significant co-morbidities (cardiovascular, chronic renal disease, inflammatory bowel disease): HR 5.814 (95%CI 1.15, 29.25), p 0.012. Lastly, genetic associations were drawn between patient genetic status as tested for other co-morbidities and prothrombotic cellular cascades, suggesting rigorous VTE assessment in patients identified with congenital or acquired mutations, namely, in CALR, JAK, MSH 2/6, MYC, and FXN.

Conclusions
Overall, this study offers the first report of UEDVT presentations in the UK with no restrictions of patient performance status or underlying co-morbidities and provides a rounded clinical picture of patient characteristics, diagnosis, management, and prognostic associations in view of rigorous guideline development.
Mathematics textbooks and curriculum resources as instruments for change
Authors: Rezat Sebastian , Fan Lianghuo , Pepin Birgit 
Published: September 2021

AbstractIn this survey paper we aim to provide an overview of research on mathematics textbooks and, more broadly, curriculum resources as instruments for change related to mathematical content, instructional goals and practices, and student learning of mathematics. In particular, we elaborate on the following themes: (1) The role of curriculum resources as instruments for change from a theoretical perspective; (2) The design of curriculum resources to mediate the implementation of reform ideas and innovative practice; (3) Teachers’ influence on the implementation of change through curriculum resources; (4) Students’ influence on the implementation of change through curriculum resources; and (5) Evidence of curriculum resources yielding changes in student-related factors or variables. We claim that, whilst textbooks and curriculum resources are influential, they alone cannot change teachers’ teaching nor students’ learning practices in times of curricular change. Moreover, more knowledge is needed about features of curriculum resources that support the implementation of change. We contend that curriculum innovations are likely to be successful, if teachers and students are supported to co- and re-design the relevant curriculum trajectories and materials in line with the reform efforts and their own individual needs.

Published: September 2021

AbstractFirst two decades of the twenty-first century are characterised by epidemics of non-communicable diseases such as many hundreds of millions of patients diagnosed with cardiovascular diseases and the type 2 diabetes mellitus, breast, lung, liver and prostate malignancies, neurological, sleep, mood and eye disorders, amongst others. Consequent socio-economic burden is tremendous. Unprecedented decrease in age of maladaptive individuals has been reported. The absolute majority of expanding non-communicable disorders carry a chronic character, over a couple of years progressing from reversible suboptimal health conditions to irreversible severe pathologies and cascading collateral complications. The time-frame between onset of SHS and clinical manifestation of associated disorders is the operational area for an application of reliable risk assessment tools and predictive diagnostics followed by the cost-effective targeted prevention and treatments tailored to the person.This article demonstrates advanced strategies in bio/medical sciences and healthcare focused on suboptimal health conditions in the frame-work of Predictive, Preventive and Personalised Medicine (3PM/PPPM). Potential benefits in healthcare systems and for society at large include but are not restricted to an improved life-quality of major populations and socio-economical groups, advanced professionalism of healthcare-givers and sustainable healthcare economy. Amongst others, following medical areas are proposed to strongly benefit from PPPM strategies applied to the identification and treatment of suboptimal health conditions:Stress overload associated pathologiesMale and female healthPlanned pregnanciesPeriodontal healthEye disordersInflammatory disorders, wound healing and pain management with associated complicationsMetabolic disorders and suboptimal body weightCardiovascular pathologiesCancersStroke, particularly of unknown aetiology and in young individualsSleep medicineSports medicineImproved individual outcomes under pandemic conditions such as COVID-19.
Engineering the Structure of Multi-thread Fancy Bouclé Yarn: Individual Effects of the Number of Wraps and the Overfeed Ratio
Authors: Alshukur Malek , Macintyre Lisa 
Published: September 2021

AbstractThis study is about the influence of the number of wraps and the overfeed ratio on the fancy bouclé yarn structure. The bouclé yarns of this study were made on a hollow-spindle spinning system. The number of wraps and the overfeed ratio were increased incrementally and individually in two different experiments. It was found that there were significant linear relationships between increasing the overfeed ratio and increasing the number and size of fancy bouclé profiles, but at the expense of decreasing their circularity ratio and changing the bouclé yarn morphology. However, increasing the number of wraps made a significant linear reduction to the size of fancy bouclé profile but without affecting their number. This study aids bouclé yarn manufacturers to increase their understanding of the structure and aesthetics of bouclé yarns. It also shows them how the morphology of bouclé profiles may change when the overfeed ratio or the number of wraps is changed. In particular, variants of bouclé profiles may appear, which can increase the potential for those variants to attract the attention of designers and consumers. It also can strengthen the manufacturers’ capabilities to satisfy the needs of a wide range of consumers, by creating a wider range of novelty clothing.
Improvement in mechanical properties in AlN-h-BN composites with high thermal conductivity
Authors: Liu Zetan , Zhao Shiqiang , Yang Tian , Zhou Ji 
Published: September 2021

AbstractIt is possible to improve the machinability of aluminum nitride-hexagonal boron nitride (AlN-h-BN) ceramics while maintaining high strength and high thermal conductivity. The composite ceramics with 0–30 wt% BN as secondary phase were prepared by hot pressed sintering, using yttrium oxide (Y2O3) as sintering aid. The phase composition, density, microstructure, mechanical properties, thermal conductivity, and dielectric properties were investigated. The sintering additives were favorable to purify the grain boundaries and improve densification, reacting with oxide impurities on the surface of raw material powder particles. The optimum BN content improved the flexural strength and fracture toughness of composite ceramics with 475 MPa and 4.86 MPa·m1/2, respectively. With increasing the amount of BN, the thermal conductivity and hardness of composites gradually decreased, but the minimum value of thermal conductivity was still 85.6 W·m−1·K−1. The relative dielectric constant and dielectric loss tangent of the samples ranged from 6.8 to 8.3 and from 2.4 × 10−3 to 6.4 × 10−3, respectively, in 22–26 GHz.
