Geometry and Proportions in Anne Tyng’s Architecture
Authors: Càndito Cristina , Meloni Alessandro 
Published: April 2022

AbstractAnne Tyng spent her long professional life devoted to architecture, mainly in its theoretical aspects linked with geometry and proportions. She is well known as one of Louis Kahn’s most important partners in her professional and private life, however a relevant degree of originality was found in her work, while exploring her architectural design through two unrealized projects. The aim of this paper is to investigate these projects by analysing the original drawings and also searching for possible geometries through three-dimensional virtual reconstructions. In this way, it is possible to detect Tyng’s propensity for complex three-dimensional geometry in her version of the project for Bryn Mawr College’s Erdman Hall (around 1960) made for Kahn’s firm, and the attention given to the relations between geometry, environment and perception in her independent project, the Four-Poster House (around 1975–1988). In both examples, Tyng paid special attention to issues related to proportion which link architecture and human beings, adopting dimensions that could fit different kinds of people.
Multi-view damage inspection using single-view damage projection
Authors: van Ruitenbeek R. E. , Bhulai S. 
Published: April 2022

AbstractSingle-view computer vision models for vehicle damage inspection often suffer from strong light reflections. To resolve this, multiple images under various viewpoints can be used. However, multiple views increase the complexity as multi-view training data, specialized models, and damage re-identification over different views are required. In addition, traditional point cloud applications require large computational power, being impractical for edge computing. Therefore, multi-view damage inspection has not yet found its way into practical applications. We present a novel approach that projects the results from widely available single-view computer vision models onto 3D representations, to combine the detections from various viewpoints. With this, we leverage all advantages of multi-view damage inspection, without the need for multi-view training data and specialized models or hardware. We conduct a practical evaluation using a drive-through camera setup, to show the applicability of the methods in practice. We show that our proposed method successfully combines similar damages across viewpoints, reducing the number of duplicate damages by almost 99%. In addition, we show that our approach reduces the number of false positives by 96%. The proposed method leverages the existing single-view training data and single-view deep learning models to make multi-view inspection more accessible for practical implementations.
How do dimensions of institutional quality improve Italian regional innovation system efficiency? The Knowledge production function using SFA
Authors: Barra Cristian , Ruggiero Nazzareno 
Published: April 2022

AbstractThis paper investigates the contribution of different dimensions of institutional quality on the efficiency of the Italian regional innovation system (RIS) through the application of a knowledge production function estimated within a Stochastic Frontier Analysis environment. Though most of the dimensions of institutional quality considered in the analysis are found to play no role in affecting RIS efficiency, we detect a positive and highly significant impact of government effectiveness on the variable of interest. This result is robust to different assumptions about the underlying technology, to alternative lag structures between R&D and patenting activities and to the application of different R&D inputs. Moreover, this evidence is confirmed once instead of the RIS efficiency, we appraise the impact of institutional quality on the amount of registered patents, through the application of a canonical knowledge production function. In terms of policy implications, our analysis indicates that measures that strengthen the endowment of regional socio-economic structures are highly recommended as they enhance the efficiency of the RIS and stimulate patenting activities. Finally, interventions for Southern regions should be designed to reduce the technological and efficiency gap with the most advanced regions in the country.

Abstract
Introduction and hypothesis
Conventional defecography and MRI defecography can be requested as an additional test for diagnosing and differentiating the type of posterior compartment prolapse and/or obstructive defecation disorders. The objective of this study was to determine the added value of conventional defecography, conventional defecography and MRI defecography for clinical decision-making on treatment for patients with posterior compartment prolapse.

Methods
Four gynecologists were asked to fill in their treatment plan per patient for 32 cases for three different steps. Step 1 consisted of information on the anamnesis and physical examination (POP-Q). Step 2 consisted of Step 1, including conventional defecography (group A) or MRI defecography (group B). In Step 3, all gynecologists received the information on Step 1 including both conventional defecography and MRI defecography. Data analysis solely focused on the assessment of changes in the gynecological treatment plan of the posterior compartment.

Results
After Step 2 a change in treatment plan occurred in 37% and 48% of the women in groups A and B, respectively. Accordingly, after Step 3 (including all imaging data), a change in treatment plan occurred in 19% and 52% of the women in groups A and B, respectively. A change within the surgery group (when a different type of surgery was selected) was seen for a total of 11 cases in group A and 20 in group B in all steps combined.

Conclusions
Both conventional defecography and MRI defecography had an large effect on the treatment plan for patients with posterior compartment prolapse. The dedicated added value of the imaging modality individually cannot be concluded yet.
Wealth inequality, systemic financial fragility and government intervention
Authors: Garcia Filomena , Panetti Ettore 
Published: April 2022

AbstractDoes wealth inequality make financial crises more likely? If so, how can a government intervene, and how does this affect the distribution of resources in the economy? To answer these questions, we study a banking model where strategic complementarities among wealth-heterogeneous depositors trigger systemic self-fulfilling runs. In equilibrium, higher wealth inequality increases directly the incentives to run of the poor, and indirectly those of the rich via higher bank liquidity insurance, thus increasing the probability of a systemic self-fulfilling run overall. A government intervention on illiquid but solvent banks redistributes resources towards the poor and makes systemic self-fulfilling runs less likely.
Exact discrete Lagrangian mechanics for nonholonomic mechanics
Authors: Simoes Alexandre Anahory , Marrero Juan Carlos , de Diego David Martín 
Published: April 2022

AbstractWe construct the exponential map associated to a nonholonomic system that allows us to define an exact discrete nonholonomic constraint submanifold. We reproduce the continuous nonholonomic flow as a discrete flow on this discrete constraint submanifold deriving an exact discrete version of the nonholonomic equations. Finally, we derive a general family of nonholonomic integrators that includes as a particular case the exact discrete nonholonomic trajectory.

Technical factors can impact on remote consultations in rheumatology: results from a service evaluation during the COVID-19 pandemic

Published: April 2022

AbstractSince the COVID-19 pandemic started, there have been changes in clinical practice to limit transmission, such as switching from face-to-face to remote consultations. We aimed to study the influence of technical factors on remote consultations in our experience during the pandemic. 12 clinicians completed data collection forms after consultations, recording the technology used (video vs phone); technical problems encountered; discharge or subsequent appointment status; and technical aspects of the consultation process using 0–10 numerical rating scales (NRS) (Time Adequate; Relevant History; Physical Exam; Management Plan; and Communication Quality). Data were collated on an MS Access 2016 database and transferred to SPSS version 25 for statistics. Of 285 forms valid for analysis, 48 (16.8%) had video consultations. Of 259 forms with technical problems data recorded, 48 (18.5%) had a technical problem. Video patients were significantly younger (mean 49.3 vs 61.3 years, p < 0.001), had higher scores on Physical Exam scale (mean 4.0 vs 2.6, p < 0.001), but had no significant difference on Management Plan scale (7.3 vs 7.2). Those with technical problems were more common among video consultations (33.3% vs 15.4%, p = 0.005), had lower scores on Time Adequate scale (7.7 vs 8.7, p < 0.001) and Communication Quality scale (7.1 vs 8.4, p < 0.001), but had no significant difference on Management Plan scale (7.3 vs 7.2). The strongest correlation of Management Plan scale was with Communication Quality scale (Rho = 0.64). Of the NRS, a 1-point reduction in scores on Management Plan scale was the strongest predictor of subsequent face-to-face appointment (Odds Ratio 1.88, 95% CI 1.58–2.24), and this remained an independent predictor in multivariate analysis (adjusted OR 1.90, 1.57–2.31). Having a technical problem was inversely associated with the outcome of a subsequent face-to-face appointment (OR 0.17, 0.04–0.74), and this remained significant after adjustment for Management Plan in multivariate analysis (adjusted OR 0.09, 0.12–0.54). Video patients were younger suggesting a preference for video amongst younger patients. Although technical problems were more common with video, having a video consultation or a technical problem had no significant impact on management plan. Scoring lower on the Management Plan scale was the strongest predictor of, and independently associated with, requesting a subsequent face-to-face appointment. The inverse relationship of technical problems with subsequent face-to-face appointment request will need validation in further studies.
Copper Toxicity in Maize: The Severity of the Stress is Reduced Depending on the Applied Fe-Chelating Agent

Published: April 2022

AbstractThe wide use of copper (Cu)-based fungicide has caused a stepwise accumulation of Cu in the environment increasing the occurrence of phytotoxicity in crops. To understand and alleviate this abiotic stress, maize seedlings were grown in hydroponic solution with different combinations of Cu and iron (Fe) forms. Results showed that maize Cu sensitivity is related to the nature of the form supplied and to the chelate-exchange processes that might involve other elements, such as Fe. The use of CuSO4 excess (100 µM) caused severe reduction of plant growth, over accumulation of Cu, high activity of antioxidant enzymes, and impairment of the acquisition of other nutrients. In presence of chelating agents (citrate and ethylenediaminetetraacetic acid, EDTA) the ability of plants to tolerate high Cu-levels depends on the Fe nutritional status. Copper phytotoxicity symptoms do not occur when Cu was supplied chelated by EDTA. The use of synthetic agent EDTA (as Cu-EDTA and Fe-EDTA) prevented the accumulation of toxic Cu-level in plants and allowed a better homeostasis among nutrients. In presence of citrate, high concentration of Cu occurred in plants but its phytotoxicity was limited when even EDTA was available in solution. Results suggest that maize plants can operate a good control of nutritional status when Cu-excess is present concomitantly with a synthetic chelator (as EDTA) even when supplied as a Fe-fertilizer. These results pave the way to provide guidelines for the fertilization managements on Cu-contaminated soils to alleviate phytotoxicity in crops.

Published: April 2022

Abstract
Purpose
To present our experience with a new microsurgical approach for treatment of the Reinke’s edema in suspension laryngoscopy–microdebridement. After a short review of existing literature we introduce speech therapy before and after the surgery into the protocol.

Methods
The authors compare the phonatory outcome, laryngostroboscopical results and subjective improvement of the voice of 30 patients with Reinke’s edema that were operated with either microdebridement or cold steel surgery techniques. “Sandwich” speech therapy strategy was applied for the vocal rehabilitation before and after surgery in both patient groups.

Results
After the microdebridement and the speech therapy the mucosal wave was regular, symmetric and periodic in all patients. No signs of abnormal scar tissue or anterior adhesions were observed. Significant improvement of vocal parameters was found after the surgery in both groups of patients: operated with the microdebridement technique and the cold steel technique. The subjective voice evaluated by Voice Handicap Index (VHI-10) was improved for both patient groups in a homogenous way.

Conclusions
Based on the similarity of the vocal outcome in the two groups, microdebridement of the vocal folds is an excellent method for removing the edema of the Reinke’s space. Careful suction at a low voltage protects the lamina propria during the microdebridement. The authors discuss the indication to this innovating procedure in patients with difficult laryngeal exposure and small operating field.
The current standing of autologous haematopoietic stem cell transplantation for the treatment of multiple sclerosis

Published: April 2022

AbstractAutologous haematopoietic stem cell transplantation (aHSCT) is gaining traction as a valuable treatment option for patients affected by severe multiple sclerosis (MS), particularly the relapsing–remitting form. We describe the current literature in terms of clinical trials, observational and retrospective studies, as well as immune reconstitution following transplantation, with a focus on the conditioning regimens used for transplantation. The evidence base predominantly consists of non-randomised, uncontrolled clinical trials or data from retrospective or observational cohorts, i.e. very few randomised or controlled trials. Most often, intermediate-intensity conditioning regimens are used, with promising results from both myeloablative and lymphoablative strategies, as well as from regimens that are low and high intensity. Efficacy of transplantation, which is likely secondary to immune reconstitution and restored immune tolerance, is, therefore, not clearly dependent on the intensity of the conditioning regimen. However, the conditioning regimen may well influence the immune response to transplantation. Heterogeneity of conditioning regimens among studies hinders synthesis of the articles assessing post-aHSCT immune system changes. Factors associated with better outcomes were lower Kurtzke Expanded Disability Status Scale, relapsing–remitting MS, younger age, and shorter disease duration at baseline, which supports the guidance for patient selection proposed by the European Society for Blood and Marrow Transplantation. Interestingly, promising outcomes were described for patients with secondary progressive MS by some studies, which may be worth taking into account when considering treatment options for patients with active, progressive disease. Of note, a significant proportion of patients develop autoimmune disease following transplantation, with alemtuzumab-containing regimens associated with the highest incidence.
A new linear combination method of haplogroup distribution central vectors to model population admixtures
Authors: Török Tibor , Maár Kitti , Varga István Gergely , Juhász Zoltán 
Published: April 2022

AbstractWe introduce a novel population genetic approach suitable to model the origin and relationships of populations, using new computation methods analyzing Hg frequency distributions. Hgs were selected into groups which show correlated frequencies in subsets of populations, based on the assumption that correlations were established in ancient separation, migration and admixture processes. Populations are defined with this universal Hg database, then using unsupervised artificial intelligence, central vectors (CVs) are determined from local condensations of the Hg-distribution vectors in the multidimensional point system. Populations are clustered according to their proximity to CVs. We show that CVs can be regarded as approximations of ancient populations and real populations can be modeled as weighted linear combinations of the CVs using a new linear combination algorithm based on a gradient search for the weights. The efficacy of the method is demonstrated by comparing Copper Age populations of the Carpathian Basin to Middle Age ones and modern Hungarians. Our analysis reveals significant population continuity since the Middle Ages, and the presence of a substrate component since the Copper Age.

We study the parameterized complexity of this problem and answer all questions by Kare and Reddy [IWOCA 2019] about the parameterized complexity of the problem. We show that the problem is W[2]-complete parameterized by k and that it does not admit a polynomial kernel parameterized by vertex cover number unless $$\mathrm {NP} \subseteq \mathrm {coNP/poly}$$

. We also show that the problem is fixed-parameter tractable parameterized by clique-width plus the maximum diameter among all connected components. This implies the fixed-parameter tractability parameterized by modular-width, by treedepth, and by distance to cographs. Using a different technique, we show that parameterization by distance to split graphs is also tractable. We finally show that the problem parameterized by max leaf number is XP.

Published: April 2022

AbstractBy using a jump transformation associated to the Romik map, we define a new continued fraction algorithm called odd-odd continued fraction, whose principal convergents are rational numbers of odd denominators and odd numerators. Among others, it is proved that all the best approximating rationals of odd denominators and odd numerators of an irrational number are given by the principal convergents of the odd-odd continued fraction algorithm and vice versa.

Published: April 2022

AbstractExtensive research has associated adolescent delinquent behavior with verbal deficits, yet for some subgroups of youth offenders better verbal ability has been associated with increased risk. This study examined associations between specific oral language skills and established markers of high-risk youth offending comprising callous and unemotional (CU) traits, early age of the first offence, and violent offending. Measures of language, CU traits, anxiety, as well as official youth justice data, were collected for adolescent male offenders and non-offenders (n = 130; aged 13–19 years; 62% youth offenders). Pragmatic language was found to be differentially associated with distinct variants of CU traits based on high/low levels of anxiety. Furthermore, among youth offenders with primary variant (low anxiety) CU traits, more violent offending was associated with better structural language skills, while earlier age of first offence was associated with better pragmatic language skills.

Published: April 2022

AbstractHyFlex termed as hybrid-flexibility is a teaching approach where teachers and students have the alternative to participate in planned courses either remotely or face-to-face. This study examines the effectiveness of the HyFlex pedagogical method to teach highly interactive digital and face-to-face cyber security training in Nigeria amidst the pandemic. Data was collected using a survey questionnaire from 113 participants to evaluate student’s perception towards the effectiveness of the Hyflex method using physical and Zoom teleconferencing which allow students to participate remotely in the cyber security training. The developed questionnaire comprising both open-ended and Likert-style questions was administered to purposely sampled participants. Findings from this study presents implementation details on how the HyFlex teaching model was implemented from a developing country context. Besides, findings present challenges and opportunities experienced with adopting the HyFlex pedagogical model, and also offers recommendations to other instructors for employing this teaching model. Findings also reveal that although there were challenges experienced by the students who attended via online such as connectivity issues, competency in using some features in Zoom-conferencing, etc. The students did appreciate the flexibility HyFlex teaching afforded, indicating that HyFlex is a promising teaching approach for fostering engagement of students especially in large-group cyber security courses.
