AbstractHandcrafting ceramic pottery in the traditional method or virtual reality (VR) with intricate surface details is still challenging for the ceramic and graphic artist. Free-form pottery modeling can be efficiently geometrically modeled with the right tools with detailed 3D print outputs, yet challenging to be manufactured using traditional art. The new advanced pottery VR simulation is a promising method to recreate the traditional pottery simulation for a better experience with some barriers. The challenges that arise from surface detail in pottery are a tedious task accomplished by mesh blending and retopology. This paper focuses on refining the VP application’s performance by adding unique sound resonance as a more likely infinite geometric phenomenon textures, blending it into the basic shapes. This paper combines creativity and visual computing technologies such as VR, mesh blending, fixing errors, and 3D printing to bring the ceramic artist’s imagination to life. We have used sound resonance with virtual pottery (VP) systems refinements to demonstrate several standard pottery methods from free form deformed pottery, retopology, mesh blended for surface details, and 3D printed pottery with materials including polymer and ceramic resins.

AbstractCognitive impairment is a common feature in schizophrenia and the strongest prognostic factor for long-term outcome. Identifying a trait associated with the genetic background for cognitive outcome in schizophrenia may aid in a deeper understanding of clinical disease subtypes. Fast sleep spindles may represent such a biomarker as they are strongly genetically determined, associated with cognitive functioning and impaired in schizophrenia and unaffected relatives. We measured fast sleep spindle density in 150 healthy adults and investigated its association with a genome-wide polygenic score for schizophrenia (SCZ-PGS). The association between SCZ-PGS and fast spindle density was further characterized by stratifying it to the genetic background of intelligence. SCZ-PGS was positively associated with fast spindle density. This association mainly depended on pro-cognitive genetic variants. Our results strengthen the evidence for a genetic background of spindle abnormalities in schizophrenia. Spindle density might represent an easily accessible marker for a favourable cognitive outcome which should be further investigated in clinical samples.

Summary
Background
Dermatitis linearis is a toxic skin lesion caused by contact with certain beetles of the genus Paederus (Coleoptera: Staphylinidae). Dermatitis linearis outbreaks have been described mainly in tropical and subtropical regions, but so far not in Central Europe, and are considered an emerging public health concern potentially associated with climate change.

Material and methods
Following diagnosis of dermatitis linearis in a cluster of six adults and one child with reported exposure to beetles with morphological characteristics of Paederus species at a recreational public open-air bath at Lake Neusiedl (Illmitz, Burgenland, Austria), we performed on-site inspection and installed light and pitfall traps. Collected beetle specimens of the genus Paederus were classified using morphological characteristics and DNA barcoding.

Results
A total of 32 Paederus beetles were collected using an aspirator (n = 2) and light traps (n = 30). No individuals of the genus Paederus were captured with the pitfall traps. Morphological analyses identified them as members of the Paederus balcanicus species, which was confirmed by genetic specification of four arbitrarily chosen individuals. Dermatitis linearis lesions were treated with topical steroids and healed but partly leaving scars and hyperpigmentation, over the course of a few weeks in all affected persons.

Conclusion
We report for the first time (a) an outbreak of dermatitis linearis associated with exposure to autochthonous Paederus species in Austria, and (b) that contact to the species Paederus balcanicus may cause dermatitis linearis in humans. Adequate measures should be taken to prevent dermatitis linearis outbreaks in areas with resident Paederus occurrence.
When and how teachers intervene in group discussions on experiences from practice in postgraduate medical education: an interactional analysis
Authors: van Braak Marije , Huiskes Mike , Veen Mario 
Published: June 2022

AbstractMedical educators constantly make decisions on when and how to intervene. Current literature provides general suggestions about types of teacher interventions. Our study aims to specify that knowledge by describing in detail the actions teachers do when intervening, the interactional consequences of those actions, and how these relate to teacher roles in group discussions. We collected all first teacher interventions (n = 142) in 41 videorecorded group discussions on experiences from practice at the Dutch postgraduate training for General Practice. We analyzed the interventions using Conversation Analysis. First, we described the timing, manner, actions, and interactional consequences of each intervention. Next, we inductively categorized actions into types of actions. Finally, we analyzed the distribution of these types of actions over the group discussion phases (telling, exploration, discussion, conclusion). First teacher interventions were done at observably critical moments. Actions done by these interventions could be categorized as moderating, expert, and evaluating actions. Moderating actions, commonly done during the telling and exploration phase, are least directive. Expert and evaluator actions, more common in the discussion phase, are normative and thus more directive. The placement and form of the actions done by teachers, as well as their accounts for doing those, may hint at a teacher orientation to intervene as late as possible. Since the interventions are occasioned by prior interaction and responded to in different ways by residents, they are a collaborative interactional accomplishment. Our detailed description of how, when and with what effect teachers intervene provides authentic material for teacher training.
The effect of ply properties in paperboard converting operations: a way to increase formability
Authors: Lindberg Gustav , Kulachenko Artem 
Published: June 2022

AbstractThis study addresses the question of how the difference in mechanical properties of the individual layers in a multi-ply commercial paperboard affects the outcome of the tray-forming operation. Two commercially produced paperboards with nearly identical mechanical properties when conventionally tensile tested were considered. These boards are produced on different machines with the same target grammage and density. Despite the similar mechanical properties, their performance in a given tray-forming operation was drastically different, with one of the boards showing an unacceptable failure rate. To investigate the difference seen during converting operations, a detailed multi-ply finite element model was built to simulate the converting operation. The present model considers a critical area of the paperboard known to exhibit failures. To derive the constitutive relations for each ply in the sub-model, both boards were split to single out individual plies which were then tensile tested. Including the properties of individual plies revealed large differences between the boards when it comes to the distribution of the properties in the thickness direction. In particular, the top plies differed to a large extent. This is attributed to the difference in refining energies for the plies. The results from the three-ply sub-model demonstrated the importance of including the multi-ply structure in the analysis. Weakening of the top ply facing the punch by using lower refining energy considerably increased the risk of failure of the entire board. These results suggest that there is room for optimizing the board performance by adjusting the refining energy at the ply level.Graphical abstract

For this we need the classification of the points, lines and planes in the projective three space under projectivities that leave the twisted cubic invariant. A line in three space determines a rational function of degree at most three and vice versa. Furthermore, the double point scheme of a rational function is studied. The pencil of a true passant of the twisted cubic, not in an osculation plane gives a curve of genus one as double point scheme. With the Hasse–Weil bound on $${\mathbb F}_q$$

AbstractThe aim of this review is to investigate the literature pertaining to the potential risks of low-dose ionizing radiation to Lynch syndrome patients by use of computed tomography (CT), either diagnostic CT colonography (CTC), standard staging CT or CT surveillance. Furthermore, this review explores the potential risks of using radiotherapy for treatment of rectal cancer in these patients. No data or longitudinal observational studies of the impact of radiation exposure on humans with Lynch syndrome were identified. Limited experimental studies utilizing cell lines and primary cells exposed to both low and high radiation doses have been carried out to help determine radio-sensitivity associated with DNA mismatch repair gene deficiency, the defining feature of Lynch syndrome. On balance, these studies suggest that mismatch repair deficient cells may be relatively radio-resistant (particularly for low dose rate exposures) with higher mutation rates, albeit no firm conclusions can be drawn. Mouse model studies, though, showed an increased risk of developing colorectal tumors in mismatch repair deficient mice exposed to radiation doses around 2 Gy. With appropriate ethical approval, further studies investigating radiation risks associated with CT imaging and radiotherapy relevant doses using cells/tissues derived from confirmed Lynch patients or genetically modified animal models are urgently required for future clinical guidance.
Teachers’ Error-handling Practices Within and Across Lesson Phases in the Mathematics Classroom
Authors: Kaufmann Odd Tore , Larsson Maria , Ryve Andreas 
Published: June 2022

AbstractMultiple studies have been conducted regarding teachers’ error-handling practices, and how errors can be treated as opportunities for learning, albeit in the context of whole-class discussions. The aim of the present research is to continue to investigate teachers’ error-handling practices as they occur in different phases of maths lessons: introduction of the task, when students are working alone, and when students are working in pairs and finally, as part of the whole-class discussion. The study included 51 lessons from twelve teachers. A cross-case analysis was made across the individual teacher cases to look for similarities and differences between different teachers’ error-handling practices across the lesson phases in order to create teaching profiles with similar handling of student errors across the lesson phases. Five error-handling teaching profiles were identified; correcting errors throughout all phases, correcting errors during students’ work while few errors are brought up in whole class, correcting errors during students’ work while using a variety of practices in whole class, ignoring errors while using some of them in whole class, and discussing and explaining errors.
Abrupt change from moderate positive to colossal negative thermal expansion caused by imidazolate composite formation

Published: June 2022

AbstractThis work describes temperature-induced crystallization processes and reaction mechanisms occurring in the borohydride-imidazolate system. In the course of thermal evolution, crystal structures of two novel bimetallic imidazolates AMnIm3 (A = Na, K) were solved using synchrotron radiation powder diffraction data. Both the alkali metal cation and the Mn cations exhibit distorted octahedral coordination while each imidazolate is surrounded by two alkali metal and two manganese atoms. Extensive study of the thermal expansion behaviour revealed that the expansion of the bimetallic imidazolates does not proceed uniformly over the entire temperature range but rather abruptly changes from a colossal negative to a moderate positive volume expansion. Such behaviour is caused by the coherent intergrowth of the coexisting phases which form a composite, a positive lattice mismatch and a tensile strain during the coexistence of NaMIm3 (M = Mg and Mn) and NaIm or HT-NaIm. Such coherent coalescence of two materials opens the possibility for targeted design of zero thermal expansion materials.

Enhancing the properties of PVDF/MFe2O4; (M: Co–Zn and Cu–Zn) nanocomposite for the piezoelectric optronic applications
Authors: El-Masry Mai M. , Ramadan Rania 
Published: June 2022

AbstractPolyvinylidene fluoride (PVDF) polymer is considered as an encouraging piezoelectric material whose optical properties need to be enhanced. Zinc ferrite is an excellent photoelectric material, in the present work it was doped separately by (cobalt and copper) ferrite. Co-ZnFe2O4 and Cu-ZnFe2O4 nanoparticles were synthesized using auto-combustion method and characterized using XRD, FTIR, FESEM and HRTEM. The crystallite size was (28.8, 35.8, 22 and 31) nm for the Co-ZnFe2O4 and Cu-ZnFe2O4 nanoparticles, while the estimated particle size from HRTEM were 55 nm for the Co-ZnFe2O4 nanoparticles and 75 nm for the Cu-ZnFe2O4. The obtained samples used as PVDF fillers, aiming to improve its optical properties. The optical properties as well as, the piezoelectric response of the prepared PVDF/(Co-ZnFe2O4 and Cu-ZnFe2O4) nanocomposites were investigated. The maximum value for refractive index was related to PVDF/Co-ZnFe2O4 nanocomposite. While, Cu-ZnFe2O4 nanoparticles have limited improvement of the PVDF optical properties. Co-ZnFe2O4 nanoparticles increases the PVDF optical conductivity σopt. four times its original value as well as the dielectric values was increased from 0.05 for neat PVDF to 2. The piezoelectric response of the PVDF polymer is clearly increased by the addition of both Co-ZnFe2O4 and Cu-ZnFe2O4 nanoparticles.
Default meanings: language’s logical connectives between comprehension and reasoning
Authors: Lobina David J. , Demestre Josep , García-Albea José E. , Guasch Marc 
Published: June 2022

AbstractLanguage employs various coordinators to connect propositions, a subset of which are “logical” in nature and thus analogous to the truth operators of formal logic. We here focus on two linguistic connectives and their negations: conjunctionandand (inclusive) disjunctionor. Linguistic connectives exhibit a truth-conditional component as part of their meaning (their semantics), but their use in context can give rise to various implicatures and presuppositions (the domain of pragmatics) as well as to inferences that go beyond semantic/pragmatic properties (the result of reasoning processes). We provide a comprehensive review of the role of the logical connectives in language and argue that three sets of factors—semantic, pragmatic, and those related to reasoning—are separate and separable, though some details may differ cross-linguistically. As a way to showcase the argument, we present two experiments in language comprehension in Spanish wherein pragmatic content was minimised and reasoning processes neutered, thus potentially highlighting what might be the default meanings of the connectives under study. In Experiment 1 we show that the conjunctive reading of inclusive disjunction is available in positive contexts other than in syntactically intricate cases such as downward entailing and free choice contexts, contrary to what has been claimed in the literature. In Experiment 2 we show that negated conjunctions and disjunctions in Spanish can easily receive the same interpretation when contrasted against the same context and, moreover, that these interpretations match those available in English, despite claims from the literature that linguistic connectives and local negation interact differently in English and Romance languages.
The effect of glucose dynamics on plasma copeptin levels upon glucagon, arginine, and macimorelin stimulation in healthy adults

Published: June 2022

Abstract
Purpose
Non-osmotic stimulation tests using glucagon, arginine, or macimorelin were recently evaluated for their ability to assess posterior pituitary function. Glucagon and arginine, but not macimorelin, stimulated copeptin secretion (a surrogate marker of vasopressin) and, therefore, provide novel tests to assess the posterior pituitary. The exact underlying mechanism behind their stimulatory effect remains elusive.

Methods
This analysis combined data from three diagnostic studies conducted at the University Hospital Basel, Switzerland. In total, 80 healthy adults underwent the glucagon (n = 22), arginine (n = 30), or macimorelin (n = 28) stimulation tests. The primary objective was to investigate glucose course upon glucagon, arginine, and macimorelin stimulation tests and its effect on plasma copeptin release.

Results
Upon glucagon stimulation, the median [IQR] glucose level at baseline was 5.0 [4.6, 5.2] mmol/l, peaked at 8.1 [7.2, 9.4] mmol/l after 30 min and decreased to a minimum of 3.8 [3.5, 4.5] mmol/l after 120 min. The median copeptin increase upon glucagon stimulation was 7.7 [2.6, 28.0] pmol/l. Upon arginine, the glucose level at baseline was 4.9 [4.8, 5.5] mmol/l, peaked at 6.0 [5.2, 6.4] mmol/l after 30 min and decreased to a minimum of 4.3 [3.8, 4.8] mmol/l after 60 min. The median copeptin increase upon arginine stimulation was 4.5 [2.9, 7.5] pmol/l. Upon macimorelin, glucose levels showed no notable dynamics over the 120 min, and no major change in copeptin was observed.
In the pooled dataset, a decrease in glucose levels was significantly correlated with copeptin increase (ρ = 0.53, p < 0.01).

Conclusion
A similar course in plasma glucose was observed in the copeptin-stimulating test, i.e., after glucagon and arginine, while macimorelin had no effect on glucose and copeptin levels. We hypothesize that a drop in glucose levels observed upon glucagon and arginine might stimulate copeptin.
Financial experts of top management teams and corporate social responsibility: evidence from China
Authors: Li Zhe , Wang Bo , Zhou Dan 
Published: June 2022

AbstractThis study examines how the financial experience of senior executives influences corporate social responsibility (CSR) performance and reporting activities. With a sample of Chinese listed companies over the period 2009–2018, we find that companies with senior executives with financial expertise are associated with higher CSR performance and tend to issue lengthier sustainability reports than companies without; in addition, the percentage of financial experts on the top management team (TMT) is positively related to CSR. We next find that such improvement in CSR is mainly driven by senior executives who have work experience in regulatory-oriented financial institutions. By examining the role of the TMT’s latitude of action, we find that the positive influence of senior executives’ financial experience on CSR is more pronounced in non-state-owned enterprises and in cash-abundant companies. Last, further analysis demonstrates that the enhancement in CSR driven by financially sophisticated executives drives firm value. The results are robust to alternative measures, sensitivity tests, and various controls for endogeneity concerns.
Scalable performance analysis method for SPMD applications
Authors: Tirado Felipe , Wong Alvaro , Rexachs Dolores , Luque Emilio 
Published: June 2022

AbstractThe analysis of parallel scientific applications allows us to understand their computational and communication behavior. One way of obtaining performance information is through performance tools. One such tool is parallel application signatures for performance prediction (PAS2P), based on parallel application repeatability, focusing on performance analysis and prediction. The same resources that execute the parallel application are used to perform its analysis, creating a machine independent model of the application and identifying its common patterns. However, the analysis is costly in terms of execution time due to the high number of synchronization communications performed by PAS2P, degrading performance as the number of processes increases. To solve this problem, we propose a model that reduces data dependency between processes, reducing the number of communications performed by PAS2P in the analysis stage and taking advantage of the characteristics of single program, multiple sata applications. Our analysis proposal allows us to decrease the analysis time by 29 times when the application scales to 256 processes, while keeping error levels below 11% in the runtime prediction. It is important to mention that the analysis time is not considerably affected by increasing the number of application processes.
