An energy, momentum, and angular momentum conserving scheme for a regularization model of incompressible flow
Authors: Ingimarson Sean 
Published: November 2021

Abstract
We introduce a new regularization model for incompressible fluid flow, which is a regularization of the EMAC (energy, momentum, and angular momentum conserving) formulation of the Navier–Stokes equations (NSE) that we call EMAC-Reg. The EMAC formulation has proved to be a useful formulation because it conserves energy, momentum, and angular momentum even when the divergence constraint is only weakly enforced. However, it is still a NSE formulation and so cannot resolve higher Reynolds number flows without very fine meshes. By carefully introducing regularization into the EMAC formulation, we create a model more suitable for coarser mesh computations but that still conserves the same quantities as EMAC, i.e., energy, momentum, and angular momentum. We show that EMAC-Reg, when semi-discretized with a finite element spatial discretization is well-posed and optimally accurate. Numerical results are provided that show EMAC-Reg is a robust coarse mesh model.

Abstract
We derive optimal reliability and efficiency of a posteriori error estimates for the steady Stokes problem, with a nonhomogeneous Dirichlet boundary condition, solved by a stable enriched Galerkin scheme (EG) of order one on triangular or quadrilateral meshes in ℝ2, and tetrahedral or hexahedral meshes in ℝ3.
Plato unmasks hidden limits of tele-education

Published: November 2021

Abstract
Plato’s powerful metaphor of the Cave, from Republic, further advances a critical assessment of the hidden limits of distance learning. In the Cave, individuals are restrained to see only straight ahead to the images projected from behind them onto the wall in front of them. As in the Cave, in tele-education the dynamism of learning is replaced by passive learning. Not only do learners become largely passive with respect to their teacher, but also to each other. These effects are masked from teacher and learner alike by the technical prowess of distance learning and teaching, a version of Plato’s Cave. Tele-education has at least three undeniably salient features: safety, convenience, and cost savings. Two and a half millennia after Plato gave us the concept of mimesis and the metaphor of the Cave, we can use these philosophical tools to unmask hidden limits of tele-education.
Coordination behavior of PPh2{C6H4[CH2N(CH2CH2)2O]-2}: Case study CdCl2[PPh2{C6H4[CH2N(CH2CH2)2O]-2}]

Abstract
The reaction between CdCl2 and PPh2{C6H4 [CH2N(CH2CH2)2O]-2} (1) in a 1:1 molar ratio resulted in the cadmium(II) complex CdCl2[PPh2{C6H4[CH2N(CH2CH2)2O]-2}] (2). The complex 2 was characterized in solution by NMR spectroscopy (1H, 13C, and 31P). Single-crystal X-ray diffraction studies revealed no intramolecular N→P interaction in 1. The phosphane ligand behaves as a P,N chelating moiety in the cadmium complex 2, thus resulting in a species containing distorted tetrahedral environments around cadmium and phosphorus. Short intermolecular interactions CH‧‧‧π aryl and CH‧‧‧O in 1 and CH‧‧‧π aryl and CH‧‧‧Cl in 2 resulted in supramolecular networks.

Abstract
Herein, the synthesis of silver nanoparticles using extracts of pistachio seed coat waste is investigated. The surface plasmon resonance peak at 443 nm was observed in the nanoparticles by using ultraviolet-visible spectroscopy (UV-Vis). To identify potential biomolecules involved in the bio-reduction of silver ions, Fourier-transform infrared spectroscopy (FTIR) was used. Scanning and transmission electron microscopy (SEM and TEM) show irregular shapes with an average size of ∼20 nm. The active surface determined by Brunauer, Emmett, and Teller analysis was 22 m2/g. The effect of silver nanoparticles on eggplants sprayed with a nanoparticle suspension of 75 mg/L led to increased plant growth and chlorophyll and carotenoid contents. The fly ash addition to the soil promoted plant growth. The highest increase in plant growth occurs when plants were sprayed with 75 ppm AgNPs in 20% fly ash amended soil.
The Role of Bias in Economic Models of Law
Authors: Miceli Thomas J. , Segerson Kathleen 
Published: November 2021

AbstractBehavioral economics has highlighted the impact of various biases on economic outcomes. This essay reviews how biases have been incorporated into economic models of the law and the resulting implications for the assessment of different legal rules and policies. It focuses on two contexts. The first concerns biases that affect consumer purchases of risky products. Using a standard accident model that incorporates various forms of consumer bias, we discuss how bias can affect the efficient assignment of liability for product-related accidents. The second context concerns biases that affect the administration of law, particularly regarding the adjudication of guilt, the lawmaking function of trials, and criminal sentencing. We examine procedural rules like precedent and sentencing guidelines, both of which are aimed at curtailing judicial bias.
Verlauf und Inhalt der religiösen Bewältigung einer lebensbedrohlichen Krankheit
Authors: Frick Eckhard , Seidl Otmar 
Published: November 2021

Zusammenfassung
Der Verlauf der religiösen Bewältigung bei einer lebensbedrohlichen Krankheit ist noch weitgehend unbekannt. Religiöse Phantasien bestimmen den Inhalt dieser Bewältigung. Modellhaft wird dies bei der HIV-Infektion vor Einführung der antiretroviralen Kombinationstherapie untersucht.
105 HIV-infizierte Männer und Frauen (55 Homosexuelle, 30 Hämophile und 20 Drogenkonsumenten) wurden in einem sozialpsychologisch-tiefenpsychologischen Interview über ihre Krankheitsbewältigung befragt. Von dieser Gruppe wurden 65 Teilnehmende nach durchschnittlich 21 Monaten einer zweiten Befragung unterzogen, um den Verlauf des religösen Copings zu erfassen. Das religiöse Coping wurde im Fremdrating mittels der Berner Bewältigungsformen nach Heim et al. (1985) und die religiösen Inhalte wurden inhaltsanalytisch bestimmt.
Religiöse Bewältigung fand fast nur bei Homosexuellen statt. Im Verlauf nahm sie hochsignifikant an Intensität ab, und zwar unabhängig von der Verschlechterung der Krankheit. Ein Drittel schöpfte Kraft und Hilfe aus den religiösen Vorstellungen, ein Fünftel sah hier die Möglickeit einer aktiven Einflussnahme oder ordnete sich dem Willen Gottes unter. Bei den Gottesbildern überwogen die des strafenden oder verzeihenden Gottes, wobei die schuldhaft erlebte Homosexualität eine wichtige Rolle spielte.
Die religiöse Bewältigung spielt vor allem zu Beginn einer lebensbedrohlichen Krankheit eine Rolle. Dabei geht es um das Verständnis der Krankheit in einem spirituellen Kontext. Die religiöse Verarbeitung von Schuldgefühlen verdient eine besondere Beachtung bei der psychosozialen Betreuung der Patienten.
Bismuth-rich bimetallic clusters (CuBi8)3+ and [MBi10]4+ (M = Pd, Pt) from ionothermal synthesis

Published: November 2021

Abstract
The reaction of Bi, BiBr3, and CuBr in the Lewis-acidic ionic liquid [BMIm]Br·4AlBr3 (BMIm = 1-n-butyl-3-limidazolium) at 180 °C yielded air-sensitive, shiny black crystals of (CuBi8)[AlBr4]2[Al2Br7]. Crystals of [MBi10][AlCl4]4 (M = Pd, Pt) were obtained by reacting Bi, BiCl3, and MCl2 under similar conditions. The structures have been determined by X-ray diffraction on single-crystals and were found to be very similar to that of the known analogues with other halogens, although not isostructural. In crystals of the complex salts, polyhedral bimetallic clusters (CuBi8)3+ or [MBi10]4+ are embedded in matrices of halogenidoaluminate anions. The heteroatomic nido-cluster (CuBi8)3+ consists of a (Bi8)2+ square antiprism η4-coordinating a copper(I) cation. In the cluster cation [MBi10]4+, the metal atoms M center a pentagonal antiprism of bismuth atoms.

Abstract
The use of independent component analysis (ICA) for the analysis of two-dimensional (2D) spin-alignment echo–T
1
7Li NMR correlation data with transient echo detection as a third dimension is demonstrated for the superionic conductor Li10GeP2S12 (LGPS). ICA was combined with Laplace inversion, or discrete inverse Laplace transform (ILT), to obtain spectrally resolved 2D correlation maps. Robust results were obtained with the spectra as well as the vectorized correlation maps as independent components. It was also shown that the order of ICA and ILT steps can be swapped. While performing the ILT step before ICA provided better contrast, a substantial data compression can be achieved if ICA is executed first. Thereby the overall computation time could be reduced by one to two orders of magnitude, since the number of computationally expensive ILT steps is limited to the number of retained independent components. For LGPS, it was demonstrated that physically meaningful independent components and mixing matrices are obtained, which could be correlated with previously investigated material properties yet provided a clearer, better separation of features in the data. LGPS from two different batches was investigated, which showed substantial differences in their spectral and relaxation behavior. While in both cases this could be attributed to ionic mobility, the presented analysis may also clear the way for a more in-depth theoretical analysis based on numerical simulations. The presented method appears to be particularly suitable for samples with at least partially resolved static quadrupolar spectra, such as alkali metal ions in superionic conductors. The good stability of the ICA analysis makes this a prospect algorithm for preprocessing of data for a subsequent automatized analysis using machine learning concepts.

Extreme 3D Image Navigation in Mobile Robotics
Authors: Noskov V. P. , Gubernatorov D. V. 
Published: November 2021

The actual problem of determining all six coordinates of the current position of a mobile robot (unmanned aerial vehicle) from 3D-range-finding images (point clouds) generated by an onboard 3D laser sensor when moving (flying) in an unknown environment is considered. An extreme navigation algorithm based on using multidimensional optimization methods is proposed. The rules for calculating the difference between 3D images of the external environment used for optimization of the functional are described. The form of the functional of the difference of 3D images for different environments (premises, industrial-urban environment, rugged and wooded areas) has been investigated. Requirements for the characteristics of the sensor and the geometry of the external environment are formulated, the fulfillment of which ensures the correct formulation and solution of the problem of extreme navigation. The optimal methods of scanning the surrounding space are described and the conditions are substantiated, the fulfillment of which ensures the solution of the navigation problem by the proposed algorithm in real time (at the rate of movement) when processing 3D images formed by modern 3D laser sensors. In particular, the dependence between the frequency of formation of 3D images and the angular and linear velocities of motion is described, which ensures that the functional of the difference of 3D images falls into the multidimensional interval of unimodality, which guarantees a direct search of global minimum in real time. Various methods of direct search for the global minimum of the functional are tested and the fastest for the case under consideration are selected. The accuracy of solving the navigation problem is estimated and a method is proposed to reduce the accumulated error, based on using an older 3D image for correcting the calculated value of the current coordinates, which has an intersection of the view area with the current view area. The proposed method, which is a modification of the reference image method, allows reduce the total error, which grows in proportion to the number of cycles of solving the extreme navigation problem, to values that ensure the autonomous functioning of transport robots and UAVs in previously unprepared and unknown environments. The effectiveness of the proposed algorithmic and developed software and hardware for extreme navigation is confirmed by field experiments carried out in real conditions of various environments.

Abstract
Background

With breast cancer becoming the most diagnosed cancer in the world, the number of breast cancer mothers with adolescent children is also rising. And for adolescent daughters, their mother server as a primary figure among the key processes of identification with their gender, femininity and sexuality. But breast cancer threats mother’s health including such a key symbol of her womanhood, the breast. Which may adversely affect the development of an adolescent daughter’s own sense of personal identity and womanhood. However, few researchers and practitioners on mother-daughter interactions in the context of breast cancer, therefor this study is aimed to reveal the nuances of interactive challenges with adolescent daughters faced by mother with breast cancer from mother’ perspective.
Methods

A qualitative study was conducted. With the sample saturation principle, data collected by semi-structured interviews with 21 breast cancer patients who are in line with breast conserving. Colaizzi’s method of phenomenology was used for data analysis and Foucauldian discourse approach was also partially integrated into the analysis for this research.
Results

Three major themes emerged from the data. The themes were the following: (1) Mothers are lost in chaos (unable to deal with the shock of cancer, powerlessness of the uncertainty about the life span, and confused about how to respond to daughter's curiosity); (2) Mothers struggle for balance (protect daughter or let her be independent, as a mother or a patient); and (3) Mothers are immersed in guilt (increasing risk of cancer for daughters, influencing the development of daughter, and bring burden to daughter).
Conclusions

Our findings explore the interaction experience of breast cancer mothers and adolescence daughters, and further reveal the nuances of mother–daughter interaction challenges faced by mother with breast cancer from mother’ perspective. To help mothers enhance interaction with their daughters and assist health practitioners to translate our findings into health interventions.

Abstract
Background: The study aimed to investigate the association between socioeconomic status and severity of oral epithelial dysplasia (OED) using current data from the Taiwanese Nationwide Oral Mucosal Screening Program (TNOMSP). Methods: This retrospective analysis was conducted in the Department of Oral and Maxillofacial Surgery at a general hospital in Taipei, Taiwan. A total of 134 participants were analysed from a previous study database of 150 patients. The inclusion criteria included age over 20 years and a history of either tobacco or betel nut use. Background information, including para-habits such as betel and tobacco use, was analysed using Pearson chi-square (χ2) test, furthermore, the correlation of background information with OED severity was investigated using logistic regression (mild or moderate/high).Results: High school education level (P<0.001), poor self-awareness (P=0.002), current betel use (P<0.001), and tobacco use (P=0.003) were highly correlated with moderate- and high-grade OED (P<0.05). The odds ratio (OR) of education status above senior high school was 0.03 (95% confidence interval [CI]: 0.01–0.15, P<0.001), while that of junior high school was 1. Current betel chewing (OR=6.57 [95% CI: 1.17–37.0], P=0.033) was significantly associated with OED severity compared with never or ex-use of betel.Conclusions: We found a strong correlation between the severity of OED and current betel use and low education status. The current study revealed the socioeconomic status, poor self-awareness, and para-habits history of the patients with OED should be evaluated to identify high-risk individuals using TNOMSP.
