Background and objective
To study the cumulative incidence and surgical treatment of midline incisional hernia (MIH) after cystectomy for bladder cancer.

Methods
In the nationwide Bladder Cancer Data Base Sweden (BladderBaSe), cystectomy was performed in 5646 individuals. Cumulative incidence MIH and surgery for MIH were investigated in relation to age, gender, comorbidity, previous laparotomy and/or inguinal hernia repair, operative technique, primary/secondary cystectomy, postoperative wound dehiscence, year of surgery, and period-specific mean annual hospital cystectomy volume (PSMAV).

Results
Three years after cystectomy the cumulative incidence of MIH and surgery for MIH was 8% and 4%, respectively. The cumulative incidence MIH was 12%, 9% and 7% in patients having urinary diversion with continent cutaneous pouch, orthotopic neobladder and ileal conduit. Patients with postoperative wound dehiscence had a higher three-year cumulative incidence MIH (20%) compared to 8% without. The corresponding cumulative incidence surgery for MIH three years after cystectomy was 9%, 6%, and 4% for continent cutaneous, neobladder, and conduit diversion, respectively, and 11% for individuals with postoperative wound dehiscence (vs 4% without). Using multivariable Cox regression, secondary cystectomy (HR 1.3 (1.0–1.7)), continent cutaneous diversion (HR 1.9 (1.1–2.4)), robot-assisted cystectomy (HR 1.8 (1–3.2)), wound dehiscence (HR 3.0 (2.0–4.7)), cystectomy in hospitals with PSMAV 10–25 (HR 1.4 (1.0–1.9)), as well as cystectomy during later years (HRs 2.5–3.1) were all independently associated with increased risk of MIH.

Conclusions
The cumulative incidence of MIH was 8% three years postoperatively, and increase over time. Avoiding postoperative wound dehiscence after midline closure is important to decrease the risk of MIH.

The Second Best City and its Laws in Plato’sStatesman
Authors: Sørensen Anders Dahl 
Published: February 2021

AbstractTaking up the controversial issue of the value of the laws of non-ideal cities in Plato’sStatesman, the paper argues for a modified version of the traditional interpretation, as defended against Christopher Rowe’s influential criticism. The paper agrees with the traditional view that the established laws of non-ideal cities are assumed to be good laws and that the Eleatic Stranger’s justification for this assumption can be found in 300b. But it also argues that this defence of the traditional interpretation must be based on a revised understanding of the role of legislation in the Stranger’s conception of ideal rule. The unique contribution of the expert to good government consists in his distinctive ability to judge what is appropriate in each case, not in his work as legislator, which, on closer inspection, turns out to be based on the very same ancestral traditions that the second best city must resort to.

Abstract

Objectives
Thrombin generation (TG) with and without thrombomodulin (TM) was evaluated in COVID-19 patients with different disease severity and thromboprophylaxis regimen, in order to understand the prothrombotic profile.

Methods
We enrolled consecutive patients with confirmed diagnosis of COVID-19 admitted to Medical Departments (MD) or Intensive Care Units (ICU), and 54 healthy controls.

Results
Eighty-nine patients were included (mean age 60.4±16.1 years, 68.5% male); 33.7% admitted to ICU. Twenty-four patients (26.9%) were enrolled before thromboprophylaxis administration; 45 patients (50.6%) received standard and 20 (22.5%) intermediate sub-therapeutic dose thromboprophylaxis. Overall, patients with COVID-19 showed a TG profile comparable to that of healthy subjects (i.e. comparable peak height, endogenous thrombin potential [ETP] with and without TM). The only exception was lag time and time to peak, prolonged in COVID-19 patients vs. controls. MD patients showed a similar TG profile to healthy controls, and ICU patients showed significantly decrease ETP (p=0.030) compared to MD. As for thromboprophylaxis, TG profile was significantly increased in COVID-19 patients without thromboprophylaxis vs. controls and vs. those with thromboprophylaxis. In this latter group, ETP inhibition was significantly decreased (p=0.0003) and positively correlated with anti-Xa activity (r=0.49, p=0.0017). However, patients with thromboprophylaxis had similar TG profile vs. controls. Intermediate dose thromboprophylaxis more effectively inhibited TG in severe COVID-19 patients by increasing ETP inhibition via ETP with TM reduction vs. standard dose.

Conclusions
COVID-19 patients showed increased TG at diagnosis. Standard thromboprophylaxis reduced TG to levels of healthy controls. Intermediate sub-therapeutic thromboprophylaxis more effectively inhibited TG by decreasing ETP with TM.
An evaluation of culture teaching and learning in a Uniwide Language Program: Teachers and students’ perspectives
Authors: Mohamed Salwa 
Published: February 2021

Abstract
It is generally accepted that culture is inseparable from language. However, the provision of culture in FL courses takes different forms. At Manchester Metropolitan University (MMU), minor route/30 credit language students in the Uniwide Language Programme are allocated 1 h for cultural studies (known as the project hour) in addition to a weekly 2 h language class. This study surveys teachers’ and students’ perceptions of the teaching of culture in MMU Uniwide language courses with the aim of discovering to what extent this promotes students’ intercultural competence (IC) based on Byram, Michael, Bella Gribkova & Hugh Starkey. 2002. Developing the intercultural dimension in language teaching: A practical introduction for teachers. Strasbourg: Council of Europe, model. Byram et al.’s model of IC involves three components: knowledge, skills and attitudes. Teachers and students’ questionnaires were used to collect their views about the project hour and were analyzed both qualitatively and quantitatively. The qualitative data, using thematic analysis showed that teachers and students’ perceptions of culture learning and teaching, in general, were in line with the recent literature on IC. However, the quantitative data did not prove that the project hour fully attends to the components of IC, even though the methods and activities used matched its requirements.
Désignation et représentation des éléments topographiques dans les dialectes de France: l’élévation de terrain
Authors: Giudice Philippe Del 
Published: February 2021

Abstract
The purpose of this article is to analyze the semantic patterns according to which rises of land are referred to in the Romance dialects of France. Using the motivational method, I examine the etymology and the semantic field of more than 80 lexical types (found in dialect atlases) and their corresponding word families, going from pre-Latin to current language. If we look at their original meanings, it appears that the words that bear the sense ‘rise of land’ first referred to the shape or the rocky/bushy/earthy nature of hills and mountains, when they did not simply represent these as borders, heaps, projections or even as blows, as bumps.
The main result of my research lies in the observation of semantic determinism. Any word that is related at one point of its history to the concept of ‘mountain’ is prone to develop (or to have developed) many – if not all – of the meanings listed above. This points out the highly probable existence of semantic laws that bind together sets of correlated notions. Using my results, I attempt to describe the global organization of meaning and its cyclical nature.
Grundzüge der sizilianischen Prosodie

Published: February 2021

AbstractThis article is concerned with basic intonational features of Sicilian, a Romance variety spoken in Sicily in Southern Italy. While there has been some research on the intonational features of the regional variety of Italian, Sicilian intonation remains undescribed. The first part of the article provides a historic overview of the dialectal configuration of Sicilian and the Sicilian-Italian diglossia. In the subsequent section we perform an intonational analysis on a Sicilian corpus containing acoustic data of 432 utterances (216 broad focus statements and 216 information-seeking yes-no questions). Once the basic intonational features of Sicilian are described and analyzed we use the informatic tool ProDis (Elvira-García et al. 2018) for a quantitative cluster analysis in order to define geoprosodic groups within Siciliy. Finally, we carry out another cluster analysis with the aim of modelling prosodic distances between Romance varieties spoken in different areas in Italy.
A graphical method for breaking logical loops based on multi-tree structure
Authors: Yang A. , Miao H. , Li N. 
Published: February 2021

Abstract
Logical loops or circular logics, interpreted as circular supporting relations among systems, remain a longstanding challenge in the probabilistic safety assessment (PSA). Logical loops are commonly found in complex industrial systems. Due to the existence of the logical loops, the minimal cut sets cannot be directly obtained. In order to solve this problem, the logical loops should be broken properly. This paper proposes a graphical method based on multi-tree structure. By constructing the simplified multi-tree, logical loops both in linearly and non-linearly interrelated systems are solved. To illustrate this method, examples of linearly interrelated systems and non-linearly interrelated systems are given in this paper. As a supplement, this method is applied to the well-known complex logical loops in the nuclear power plant. It shows that this method is highly intuitive and efficient by means of graphs.

Published: February 2021

Abstract

Background
Autologous stem cell transplantation (ASCT) is one of the standard treatments of choice for eligible multiple myeloma (MM) patients. Herein, we aimed to analyze MM patients at our center and compare the clinical outcomes of single and double ASCT patients.

Materials and methods
Patients who were diagnosed as having MM and had undergone single or double ASCT in our clinic between the years 2003 and 2020 were retrospectively examined.

Results
In this study, the median time of second ASCT is approximately 3.6 years from the first ASCT. Overall survival (OS) duration of the single and double transplanted groups was 4,011 ± 266 vs 3,526 ± 326 days, respectively (p: 0.33). Progression-free survival (PFS) duration of the single and double transplanted groups was 2,344 ± 228 vs 685 ± 120 days, respectively (p: 0.22). Disease assessment after ASCT stable or progressive disease, partial remission, and very good partial or complete remission (CR) in single and double ASCT groups was 62/44/105 and 8/4/5, respectively (p: 0.22).

Conclusion
The present study points out that the second ASCT treatment option for MM patients may not be effective as suggested, especially in the era of novel MM drugs, since our results come from the past data that novel drugs were not exist. In conclusion, we found no benefit with second ASCT in MM patients in terms of PFS and OS or CR rates, and the novel anti-myeloma drugs might decrease the need for a second transplant.
Outer and inner approximations in quantum spaces

Published: February 2021

AbstractThe present paper introduces and studies the concepts ofK-outer approximation andK-inner approximation for a monotone functionμdefined on aD-posetP, by a subfamilyKofP. Some desirable properties ofK-approximable functions are established and it is shown that the family of all elements ofPthat possessK-approximation, forms a lattice and is closed under orthosupplementation. We have proved that a submodular measure on a suitable subfamily ofPhavingK-outer approximation can be extended to a function that hasK-outer approximation, and a tight function that hasK-inner approximation can be extended to a function havingK-inner approximation.
Fatigue life performance of multi-material connections hybrid joined by self-piercing rivets and adhesive
Authors: Presse Jan , Michler Thorsten , Künkler Boris 
Published: February 2021

Abstract
The multi-material design presented contains EN AW-6016 aluminum and high strength CR330Y590T-DP steel. This dissimilar combination is an example of an affordable lightweight design solution, but it requires an adapted joining technology. Hybrid joining technologies such as selfpiercing riveting (SPR) in combination with a structural adhesive enables an assembly of such dissimilar material combinations. In addition to higher manufacturing costs for mechanical joining the design process still requires a great amount of effort. This study provides a simple approach for assessing hybrid joined multi-material connections. Therefore, tests for several combinations of the most relevant parameters on fatigue life (material properties, sheet thickness, load cases) were performed under quasi-static and cyclic loads. Based on the data acquired, it is shown that the fatigue life of hybrid joined connections can be estimated by superposing the contributing fatigue life of purely SPR and purely adhesive joints.
Effects of thread rolling processing parameters on mechanical properties and microstructures of high-strength bolts
Authors: Aktas Serkan , Kisioglu Yasin 
Published: February 2021

Abstract
Bolt production with a grade of 10.9 class quality made from AISI4140 material with a low thread rolling index is usually implemented in accordance with the thread rolling method (cold forming) in industrial applications. In this method, the effects of die revolutions and multiple passes are unknown in the thread forming process as the devices are usually operated with respect to geometrical dimensions but not the mechanical properties and microstructures of the material. In the literature there are few studies on microstructures of low-carbon steel having a higher thread rolling index in bolt production. This study experimentally examined the effects of the processing parameters on the mechanical properties and microstructures. Parameters such as forming speed and single or multi-pass influences were considered in the production of M12 × 1.75 and M20 × 2.5 fasteners widely used in industrial applications. The experiments identified the behavior of the mechanical properties, microstructures and micro-hardness of the AISI4140 material at two forming speeds (rpm) and three passes in the thread rolling process. Thus, significantly sensible outcomes as a function of processing parameters were obtained considering the thread strength viewpoints.

Do Spanish causal connectives vary in subjectivity? What crowdsourcing data reveal about native speakers’ preferences
Authors: Santana Andrea , Spooren Wilbert , Nieuwenhuijsen Dorien , Sanders Ted J.M. 
Published: February 2021

AbstractLanguage users have preferences for the connectives they choose to express causal relations. These choices may depend on the subjectivity involved in the relation. Dutch connectives illustrate this situation clearly:want(‘since/for’) is preferred typically for expressing subjective relations andomdat(‘because’) for objective ones. While various corpus-based studies have revealed a similar pattern in other languages, little attention has been paid to Spanish from this perspective. Recent corpus-based studies analyzed the connectivesporque(‘because’),ya que(‘since’) andpuesto que(‘given that’) using two different methods of analysis. Surprisingly, the findings did not coincide with the previous literature on Spanish connectives, and the semantic profile of such connectives in terms of subjectivity remained unclear. The current study again aims to investigate whether these connectives show systematic variation in terms of subjectivity, using crowdsourcing experimentation. Results show that Spanish native speakers preferpuesto queoverporqueto express subjective relations. However, no statistically significant difference was observed betweenporqueandya que. This study offers a better understanding of Spanish connectives in terms of subjectivity. Furthermore, it contributes to the assessment of the use of crowdsourcing as a useful and reliable method to elucidate the meaning and use of connectives.

Abstract

Background
Vitamin D is recognized to be an immune regulator. Also, it is known to have antiviral effects by several mechanisms, including reducing inflammatory cytokines.

Objectives
To examine the 25-hydroxyvitamin D (25(OH)D) status for assessing the severity of COVID-19.

Methods
This study consisted of 596 patients confirmed as SARS-CoV-2 infection and 59 healthy individuals. The cases separated into non-severe group, severe survival, and severe non-survival group. 25(OH)D and other laboratory parameters were evaluated retrospectively.

Results
In all COVID-19 groups 25(OH)D levels were low compared to controls (p<0.05). 25(OH)D concentrations were lowest in patients in severe non-survival groups than those in other SARS-CoV-2 infection groups (p<0.05). Multivariate regression analysis exhibited that decreasing 25(OH)D was associated with an increased likelihood of non-severe, severe survival and severe non-survival disease. There were significant associations between 25(OH)D and certain inflammatory and hemostatic parameters (p<0.05, for all).

Conclusions
25(OH)D deficiency was observed among patients with COVID-19. Declined steadily 25(OH)D levels make a huge contribution to the scale of the progression of the disease. Correlations support that 25(OH)D may be a substantial tool for utilizing the severity of the disease and estimating the survival. Also, supplementation of 25(OH)D might slow down the course of the COVID-19.

Abstract
The electron paramagnetic resonance (EPR) parameters (g factor g

, and hyperfine structure constants A

i
, with i = x, y, z) and local structures for Cu2+ centers in M2Zn(SO4)2·6H2O (M = NH4 and Rb) are theoretically investigated using the high order perturbation formulas of these EPR parameters for a 3d
9 ion under orthorhombically elongated octahedra. In the calculations, contribution to these EPR parameters due to the admixture of d-orbitals in the ground state wave function of the Cu2+ ion are taken into account based on the cluster approach, and the required crystal-field parameters are estimated from the superposition model which enables correlation of the crystal-field parameters and hence the studied EPR parameters with the local structures of the Cu2+ centers. Based on the calculations, the Cu–H2O bonds are found to suffer the axial elongation ratio δ of about 3 and 2.9% along the z-axis, meanwhile, the planar bond lengths may experience variation ratio τ (≈3.8 and 1%) along x- and y-axis for Cu2+ center in (NH4)2Zn(SO4)2·6H2O and Rb2Zn(SO4)2·6H2O, respectively. The theoretical results show good agreement with the observed values.
