Geometric Constructions Using Origami
Authors: Ben-Ari Mordechai 
Published: September 2022

AbstractThis chapter shows that constructions with origami are more powerful than constructions with a straightedge and compass. We give two constructions for trisecting an angle, one by HisashiAbe (Sect. 12.1) and the other by George E. Martin (Sect. 12.2), two constructions for doubling a cube, one by Peter Messer (Sect. 12.3) and the other by Marghareta P. Beloch (Sect. 12.4), and the construction of a nonagon, a regular polynomial with nine sides (Sect. 12.5).
Are Triangles with Equal Areas and Perimeters Congruent?
Authors: Ben-Ari Mordechai 
Published: September 2022

AbstractAre two triangles with the same area and the same perimeter congruent? Not necessarily: the triangles with sides (17, 25, 28) and (20, 21, 29) both have perimeter 70 and area 210 but they are not congruent (Fig. 15.1).
Trisection of an Angle
Authors: Ben-Ari Mordechai 
Published: September 2022

AbstractIt is impossible to trisect an arbitrary angle (divide the angle into three equal parts) using only a straightedge and compass. Trisection requires the construction of cube roots, but a straightedge and compass can only construct lengths that are expressions built from integers, the four arithmetic operators and square roots. This was proved by Pierre Wantzel in 1837. Nevertheless, innumerable amateurs continue to attempt to trisect an angle. Their constructions are approximations though they are convinced that the constructions are correct. Section 2.1 presents two such constructions, develops formulas for the angles and shows the errors in the approximations.
Squaring the Circle
Authors: Ben-Ari Mordechai 
Published: September 2022

AbstractSquaring the circle, the construction of a square with the same area as a given circle, is one of the three construction problems that the Greeks posed but were unable to solve. Unlike trisecting the angle and doubling the cube, where the impossibility follows from properties of the roots of polynomials, the impossibility of squaring the circle follows from the transcendentality of 𝜋: it is not the root of any polynomial with rational coefficients. This is a difficult theorem that was proved in 1882 by Carl von Lindemann.
Solving Quadratic Equations
Authors: Ben-Ari Mordechai 
Published: September 2022

AbstractPoh-Shen Loh proposed a method for solving quadratic equations that is based on a relation between the coefficients of the quadratic polynomial and its roots. Section 7.1 reviews the traditional methods for solving quadratic equations. Section 7.2 tries to convince the reader that Loh’s method makes sense and then explains howto compute the roots. In Sect. 7.3 the computation is carried out for two quadratic polynomials and a similar computation for a quartic polynomial. Section 7.4 derives the traditional formula for the roots from Loh’s formulas.
M2-branes wrapped on a topological disk
Authors: Suh Minwoo 
Published: September 2022

Abstract
Employing the method applied to M5-branes recently by Bah, Bonetti, Minasian and Nardoni, we study M2-branes on a disk with non-trivial holonomies at the boundary. In four-dimensional U(1)4-gauged $$ \mathcal{N} $$
N
= 2 supergravity, we find supersymmetric AdS2 solutions from M2-branes wrapped on a topological disk in Calabi-Yau two-, three- and four-folds. We uplift the solutions to eleven-dimensional supergravity. For the solutions from topological disk in Calabi-Yau four-folds, the Bekenstein-Hawking entropy is finite and well-defined. On the other hand, from the topological disk in Calabi-Yau two- and three-folds, we could not find solutions with finite Bekenstein-Hawking entropy.
Symplectic Grassmannians, dual conformal symmetry and 4-point amplitudes in 6D
Authors: Bering Klaus , Pazderka Michal 
Published: September 2022

Abstract
We investigate a new algebra-based approach of finding Grassmannian formulas for scattering amplitudes. Our prime motivation is massive amplitudes of 4D $$ \mathcal{N} $$
N
= 4 SYM, and therefore we consider a 6D Grassmannian formula, where we can take advantage of massless kinematics. We next use symmetry arguments, and in particular, 6D dual conformal symmetry generalized to arbitrary dual conformal weights. Assuming a rational ansatz in terms of Plücker coordinates (i.e. minors) for the integrand, this approach leads to a set of algebraic equations. As an example, we explicitly find the solution for 4-point scattering amplitudes up to proportionality constants.
Search for Milli-Charged particles from the Sun at IceCube
Authors: Xu Ye 
Published: September 2022

Abstract
It is assumed that heavy dark matter particles ϕ with O(TeV) mass captured by the Sun may decay to relativistic light milli-charged particles (MCPs). These MCPs could be measured by the IceCube detector. The massless hidden photon model was taken for MCPs to interact with nuclei, so that the numbers and fluxes of expected MCPs and neutrinos may be evaluated at IceCube. Based on the assumption that no events are observed at IceCube in 6 years, the corresponding upper limits on MCP fluxes were calculated at 90% C. L. These results indicated that MCPs could be directly detected in the secondaries’ energy range O(100GeV)-O(10TeV) at IceCube, when ϵ2 ≳ 10−10. And a new region of 0.6 MeV < mMCP < 10 MeV and 6 × 10−6 < ϵ ≲ 10−4 is ruled out in the mMCP-ϵ plane with 6 years of IceCube data.

Abstract
Background
The British Police Service and Armed Forces are male-dominated occupations, characterised by frequent trauma exposure and intensive demands. Female police employees and military personnel may have unique experiences and face additional strains to their male counterparts. This analysis compared the levels of post-traumatic stress disorder (PTSD), hazardous/harmful alcohol consumption, and comorbidity in female police employees and military personnel.

Methods
Police data were obtained from the Airwave Health Monitoring Study (N = 14,145; 2007–2015) and military data from the Health and Wellbeing Cohort Study (N = 928; phase 2: 2007–2009 and phase 3: 2014–2016). Multinomial/logistic regressions analysed sample differences in probable PTSD, hazardous (14–35 units per week) and harmful (35 + units per week) alcohol consumption, and comorbid problems. We compared covariate adjustment and entropy balancing (reweighting method controlling for the same covariates) approaches.

Results
There were no significant differences in probable PTSD (police: 3.74% vs military: 4.47%) or hazardous drinking (police: 19.20% vs military: 16.32%). Female military personnel showed significantly higher levels of harmful drinking (4.71%) than police employees (2.42%; Adjusted Odds Ratios [AOR] = 2.26, 95% Confidence Intervals [CIs] = 1.60–3.21), and comorbidity (1.87%) than police employees (1.00%, AOR = 2.07, 95% CI = 1.21–3.54). Entropy balancing and covariate-adjustments obtained the same results.

Conclusions
Comparable levels of probable PTSD were observed, which are slightly lower than estimates observed in the female general population. Future research should explore the reasons for this. However, female military personnel showed higher levels of harmful drinking than police employees, emphasising the need for alcohol interventions in military settings.
A specific slip length model for the Maxwell slip boundary conditions in the Navier–Stokes solution of flow around a microparticle in the no-slip and slip flow regimes
Authors: Wedel Jana , Štrakl Mitja , Ravnik Jure , Steinmann Paul , Hriberšek Matjaž 
Published: September 2022

Abstract
In the case of microscopic particles, the momentum exchange between the particle and the gas flow starts to deviate from the standard macroscopic particle case, i.e. the no-slip case, with slip flow occurring in the case of low to moderate particle Knudsen numbers. In order to derive new drag force models that are valid also in the slip flow regime for the case of non-spherical particles of arbitrary shapes using computational fluid dynamics, the no-slip conditions at the particle surface have to be modified in order to account for the velocity slip at the surface, mostly in the form of the Maxwell’s slip model. To allow a continuous transition in the boundary condition at the wall from the no-slip case to the slip cases for various Knudsen (Kn) number value flow regimes, a novel specific slip length model for the use with the Maxwell boundary conditions is proposed. The model is derived based on the data from the published experimental studies on spherical microparticle drag force correlations and Cunningham-based slip correction factors at standard conditions and uses a detailed CFD study on microparticle fluid dynamics to determine the correct values of the specific slip length at selected Kn number conditions. The obtained data on specific slip length are correlated using a polynomial function, resulting in the specific slip length model for the no-slip and slip flow regimes that can be applied to arbitrary convex particle shapes.

A skill- and feature-based approach to planning process monitoring in assembly planning

Published: September 2022

AbstractFrequent changes in customer needs and large product variety are forcing manufacturing companies to move from mass production to mass customization. Customized production can be achieved by introducing reconfigurable production systems (RMS). The customized flexibility and several characteristics of RMSs provide many opportunities in terms of process and production planning. However, those characteristics greatly increase the complexity of the design and planning of production systems. This paper presents a decision support system relying on a skill-based approach to design a reconfigurable assembly line considering the planning of assembly processes and monitoring. The proposed decision aid system is modular in design and is composed of four modules. The main input data is a CAD model of a new product variant for the identification of the assembly and monitoring requirements. Besides, a current assembly system layout with its resource descriptions exists. In the first developed module, assembly-by-disassembly and a skill-based approach are used to generate different assembly plans. In the second module, feature recognition and skill-based approaches generate process monitoring alternatives. The third module uses a linear program (LP) that aims to minimize the total cost of workstation activation and reconfiguration, as well as cycle time, and to maximize the process quality of the assembly tasks. A user-based generative model design approach is applied to optimize the values of three objective functions. In the fourth and final module, a simulation of the optimized assembly plan allows either the validation of the assembly plan and process monitoring plan or initiates a new iteration due to their infeasibility. To further demonstrate how the proposed methodology works, some computational experiments are provided for two use cases.

Published: September 2022

AbstractIntroductionThere are unique technical and management challenges associated with living donor liver transplantation (LDLT) for Budd‐Chiari Syndrome (BCS). The outcomes of LDLT for BCS in comparison to other indications remain unclear and warrant elucidation.MethodsData of 24 BCS patients who underwent LDLT between January 2012 and June 2019 were analyzed. There were 20 adults and 4 children. The early and long‐term outcomes of adult LDLT BCS patients were compared to a control group of LDLT patients for other indications and matched using propensity scoring methodology.ResultsPrimary BCS was observed in 18 (90%) patients. Caval replacement was performed in 7 (35%) patients. Early and late hepatic venous outflow tract (HVOT) complications were seen in 1 (5%) and 3 (15%) patients. Preoperative acute kidney injury was identified as a risk factor for mortality in the BCS cohort (p = 0.013). On comparison, BCS recipients were younger with fewer comorbidities, more large volume ascites and higher rates of PVT. They also had longer cold ischemia time, increased blood loss and transfusion requirements, increased hospital stay, and higher late outflow complications. The 1‐year and 3‐year survivals were similar to non‐BCS cohort (84.2% vs. 94% and 71.3% vs. 91.9%, respectively, log rank test p = 0.09).ConclusionLDLT is a good option for symptomatic BCS who have failed non‐transplant interventions. The clinical and risk factor profile of BCS recipients is distinct from non‐BCS recipients. By following an algorithmic management protocol, we show on propensity‐score matched analysis that outcomes of LDLT for BCS are similar to non‐BCS indications.
Design und feldtheoretische Analyse einer Hochfeldspule
Authors: Beigelbeck Roman , Keplinger Franz 
Published: September 2022

ZusammenfassungDie Entwicklung einer Hochfeldspule für magnetische Flussdichten bis an die 40 Tesla gestaltet sich als sehr anspruchsvolle Aufgabe. Um die angestrebten hohen Magnetfelder erreichen zu können, muss die Spule nämlich im Grenzbereich ihrer maximalen mechanischen, thermischen und elektrischen Belastbarkeit betrieben werden. Im ersten Teil dieses Artikels werden der grundlegende Spulenaufbau beschrieben und konstruktions- und betriebstechnische Maßnahmen umrissen, die einen sicheren Betrieb bezüglich mechanischer und thermischer Belastungen gewährleisten. Der zweite Teil (Hauptteil) widmet sich einem feldtheoretischen, analytischen Modell, über das sämtliche elektromagnetische Feldgrößen im Spulenbereich sowie entscheidende elektrische Spulenparameter und Spuleneigenschaften im Vorfeld effizient abgeschätzt werden können. Mithilfe dieses erstmalig präsentierten Modells kann gezeigt werden, dass innerhalb der Spule elektrische Resonanzen auftreten können. Dieser Effekt ist besonders gefährlich, da er nicht unmittelbar ersichtlich bzw. erwartbar ist und bei Anregung durch die Spulenspeisung zum elektrischen Durchbruch und damit zur Zerstörung der Spule führen kann.

Published: September 2022

Abstract
Aims
To investigate the impact of SARS-COV-2 vaccination on the glycaemic control in children and adolescents with T1DM wearing continuous glucose monitoring (CGM).

Methods
Caregivers of children and adolescents with T1DM were questioned regarding SARS-CoV-2 vaccination during their regular visits at the Pediatric Diabetes Outpatient Clinic. Data regarding Time in Range (TIR) (glucose levels: 70–180 mg/dl) 7 days prior and 7 days after a vaccination dose were collected in patients wearing CGM and data regarding insulin daily doses were also obtained for the insulin pump users.

Results
From a total of 135 patients eligible for SARS-CoV-2 vaccination, 70 (51.9%) children (37 boys, 52.9%) were vaccinated with at least one dose. Seven patients received only one dose, whereas two children received a third booster shot. No statistically significant difference was observed in either TIR (64.19% post vs. 65.53% pre, p = 0.158) or total daily insulin dose (40.08 U/day post vs. 39.32 U/day pre, p = 0,282). Additionally, in ten patients on Hybrid Closed-Loop System the percentage of the automated insulin boluses given post-vaccination was not statistically significant different compared to the boluses given pre-vaccination (15.80% vs. 16.90%, p = 0,491).

Conclusions
Vaccination against SARS-CoV-2 in children and adolescents with T1DM is safe and is not associated with immediate glucose imbalance.

Published: September 2022

AbstractParkinson’s disease (PD) is characterized by motor symptoms often experienced in concomitance with non-motor symptoms (NMS), such as depression, apathy, pain, sleep disorders, and urinary dysfunction. The present study aimed to explore the effect of safinamide treatment on NMS and quality of life in motor-fluctuating PD patients. VALE-SAFI is an observational single-centre study performed in fluctuating PD patients starting safinamide treatment and followed for 6 months. The effects of safinamide on NMS, sleep, fatigue, depression and pain were assessed through validated sales. Changes in the scales from baseline to the 6-month follow-up visit were analysed. 60 PD patients (66.67% males) were enrolled at baseline, and 45 patients completed the 6-month follow-up. PD patients improved motor symptoms at follow-up, with the significant reduction of motor fluctuations. The global score of the NMS Scale significantly decreased between baseline and the follow-up. Regarding pain domains, patients reported a significant improvement in discolouration and oedema/swelling. Further, a significant improvement was observed from baseline to follow-up in sleep quality measured through the Pittsburgh Sleep Quality Index, while no changes were documented in daytime sleepiness. No differences were found in depression and fatigue between baseline and follow-up. Finally, the patient’s perception of the impact of PD on functioning and well-being decreased from baseline to follow-up. The present findings confirmed the beneficial effect of safinamide on both motor and non-motor symptoms, also improving the quality of life of PD patients. Furthermore, these data support the positive effects of safinamide on pain and mood, as well as on sleep quality and continuity.
Deep learning for compressive sensing: a ubiquitous systems perspective
Authors: Machidon Alina L. , Pejović Veljko 
Published: September 2022

AbstractCompressive sensing (CS) is a mathematically elegant tool for reducing the sensor sampling rate, potentially bringing context-awareness to a wider range of devices. Nevertheless, practical issues with the sampling and reconstruction algorithms prevent further proliferation of CS in real world domains, especially among heterogeneous ubiquitous devices. Deep learning (DL) naturally complements CS for adapting the sampling matrix, reconstructing the signal, and learning from the compressed samples. While the CS–DL integration has received substantial research interest recently, it has not yet been thoroughly surveyed, nor has any light been shed on practical issues towards bringing the CS–DL to real world implementations in the ubiquitous computing domain. In this paper we identify main possible ways in which CS and DL can interplay, extract key ideas for making CS–DL efficient, outline major trends in the CS–DL research space, and derive guidelines for the future evolution of CS–DL within the ubiquitous computing domain.
The Persistent Interlocutor
Authors: Grefte Job de 
Published: September 2022

AbstractA Persistent Interlocutor (PI) is someone who, in argumentative contexts, does not cease to question her opponent’s premises. The epistemic relevance of the PI has been debated throughout the history of philosophy. Pyrrhonians famously claim that our inability to dialectically vindicate our claims against a PI implies scepticism. Adam Leite disagrees (2005). Michael Resorla argues that the debate is based on a false premise (2009). In this paper, I argue that these views all fail to accurately account for the epistemic relevance of the PI. I then briefly present an account that aims to do better in this regard, based on the modal notion of safety. On the account proposed, the PI does not violate epistemic or dialectical norms. Rather, her behaviour tends to be epistemically perverse in the sense that it wastes cognitive resources. Perhaps surprisingly, this defect turns out not to be unique to the PI.
The Emotional Machiavellian: Interactions Between Leaders and Employees
Authors: Liyanagamage Nilupulee , Fernando Mario , Gibbons Belinda 
Published: September 2022

AbstractThis paper examines the emotional processes in Machiavellian leadership. The leadership literature portrays Machiavellians as ‘dark’ individuals that engage in unethical actions, causing employee dissatisfaction, distress, emotional exhaustion and high turnover. However, research has seldom questioned the processes behind these unethical and negative outcomes. This study explores Machiavellian emotional processes at multiple levels—within-persons and relational levels (between-persons and interpersonal interactions in organisations). In this study, emotions and leadership are not explored in isolation but as social processes that occur in relationships between leaders and employees in evolving organisational settings. This study draws on 20 participants from four large multi-national construction firms in Sri Lanka. Open-ended semi-structured interviews were conducted to explore the emotions of Machiavellians in organisations. The findings suggest that Machiavellianism influences leader and employee emotional processes. Furthermore, the emotional processes, influenced by Machiavellianism, appear to facilitate the development of leader and employee relationships and emotional experiences at within-persons and relational levels in organisations.
Problematic Internet Use Among Adolescent Male and Female Psychiatric Inpatients: A Gender Perspective
Authors: Winds Kornelius , Aebi Marcel , Plattner Belinda 
Published: September 2022

AbstractProblematic internet use (PIU) is of treatment interest in adolescent clinical samples. Gender specific differences in terms of personality traits and psychopathological symptoms remain unclear. In an adolescent clinical sample (n = 104; 69 girls) PIU, psychopathology, temperament and character traits as well as emotional and behavioral problems were assessed. 62% of the sample showed subthreshold PIU and 34% full PIU (fPIU). Boys reported more gaming whereas girls social networking. Sex specific analyses revealed gender differences: Girls with fPIU scored significantly higher on internalizing/externalizing problems/behavior, novelty seeking and transcendence, and lower on persistence, self-directedness, and cooperativeness than girls without fPIU. Boys with fPIU scored significantly higher on internalizing problems and self-transcendence and lower on harm avoidance than boys without fPIU. Gender plays an important role in PIU. Gender specific differences in both application use as well as symptomatic, temperament and character traits call for a gender specific approach in prevention and treatment integration.
Gravitomagnetic induction in the field of a gravitational wave
Authors: Ruggiero Matteo Luca 
Published: September 2022

AbstractThe interaction of a plane gravitational wave with test masses can be described in the proper detector frame, using Fermi coordinates, in terms of a gravitoelectric and a gravitomagnetic field. We use this approach to calculate the displacements produced by gravitational waves up to second order in the distance parameter and, in doing so, we emphasize the relevance of the gravitomagnetic contribution related to gravitational induction. In addition, we show how this approach can be generalized to calculate displacements up to arbitrary order.
