Authors: Maß Reinhard 
Published: March 2022

ZusammenfassungEinleitung Die Übernahme von Selbstverantwortung gilt in allen Therapieschulen als eine wichtige Voraussetzung für den Erfolg einer Psychotherapie. Selbstverantwortung wird in der hier vorgelegten Arbeit als die Bereitschaft einer Person definiert, Verantwortung für das eigene Verhalten, die eigenen Entscheidungen und alle positiven oder negativen Konsequenzen, die sich daraus ergeben, zu akzeptieren.Forschungsziele In der hier vorgelegten Arbeit wird die Bedeutung der Selbstverantwortung für einige Aspekte der Lebensqualität untersucht, namentlich für die Zufriedenheit mit der Partnerschaft, der Sexualität, der eigenen Person und der Beziehung zu den eigenen Kindern.Methoden In einer Online-Studie wurde bei 215 gesunden Erwachsenen das „Selbstverantwortungs-Inventar“ (SV-I) eingesetzt, ein neuartiger Fragebogen mit den Unterskalen „Fremdbestimmung“, „Selbstbestimmung“ und „Orientierung an den Erwartungen anderer“. Zusätzlich wurde der „Fragebogen zur Lebenszufriedenheit“ (FLZ) verwendet.Ergebnisse Signifikante Korrelationen zeigten sich für alle drei SV-I-Unterskalen: Je höher die Selbstverantwortung, desto größer die Zufriedenheit in allen vier untersuchten Bereichen der Lebensqualität.Schlussfolgerung Diese Ergebnisse bestätigen die Relevanz von Selbstverantwortung für die erfolgreiche Gestaltung sozialer Beziehungen und partnerschaftlicher Sexualität. Implikationen für die Psychotherapie werden diskutiert.

Die Würdigung von Dynamiken der Selbstbildung ist anregend für Reflexionen zur eigenen Position und Haltung gerade in sexualpädagogischen Praxiszusammenhängen. Bezüge auf die sexuelle Bildung erweitern dort fachliches Know-how und das sexualpädagogische Spektrum insgesamt. Darin liegen einige Potenziale für die konzeptionelle Weiterentwicklung der Sexualpädagogik, insbesondere auch im institutionellen Kontext.
Adipokine ZAG Alters Depression-Like Behavior by Regulating Oxidative
Stress in Hippocampus
Authors: Sun Huangbing , Ma Fuli , Chen Wenjing , Yang Xiaojing 
Published: March 2022

AbstractZinc-α2-glycoprotein (ZAG) is an adipokine involved in body metabolism,
and now it has been shown to be present in the brain and play a role in some
neurological diseases such as epilepsy and Alzheimer’s disease. In the
present study, we employed ZAG knockout (KO) mice to investigate the effects of
ZAG on behaviors after fasting and in vitro used overexpression (OV) ZAG in
HT-22 cells to further clarify the possibly underlying mechanism. The results
showed that ZAG exists widely in the brain tissues of mice and significantly
increased during fasting. In ZAG KO group the depression-like behaviors were
significantly increased after fasting for 24 hours, meanwhile the
hippocampal reactive oxygen species (ROS) content was significantly increased.
In vitro, serum deprivation led to the increasing of neuronal death and ROS, the
reduced mitochondrial membrane potential and ATP levels, while ZAG
overexpression alleviated these negative effects. The β3 adrenoreceptor
(β3AR)/protein kinase A (PKA)/cAMP response
element-binding (CREB) pathway possibly mediated the effects of ZAG on
antioxidation. These results proposed a possible target for novel therapeutic
approaches to the treatment of depression and provide potential link between
adipose tissue and psychiatric disease.

Authors: Pineiro Marta , Brandão Pedro , Burke Anthony J. 
Published: March 2022

AbstractTryptanthrin is a golden-yellow, naturally occurring alkaloid that can be obtained from multiple sources and through different synthetic methodologies. This tetracyclic compound displays several relevant biological activities. The potential of this tetracyclic alkaloid has been widely explored, and several researchers have focused their attention on expanding the variety of tryptanthrin derivatives by using a range of synthetic strategies. In this short review, we aim to address recent developments in the synthesis of the tryptanthrin core, as well as the development of new strategies employed by synthetic organic chemists to obtain novel tryptanthrin derivatives with potential biological activity, using different tools from the chemists’ toolbox, such as photocatalysis, solvent-free approaches, and multicomponent reactions.
Influence of Periapical Lesion on Healing in Sinus after Endodontics
Authors: Migas Klaudia , Marchlewska Joanna 
Published: March 2022

Abstract
Objective The goal of primary and secondary endodontic treatment is to eliminate the cause of inflammation inside the tooth and in the surrounding tissues. When the inflammation from the root canal system of the tooth spreads beyond the apex of the root, periapical changes in the bone tissue and, in the case of upper premolars and molars, inflammatory changes in the Schneider membrane may occur.
Materials and Methods In a retrospective documentation analysis of root canal treatments, three-dimensional (3D) computed tomography images before and after endodontic treatment were assessed to measure the thickness of the Schneider membrane. Forty-five endodontically treated patients aged 21 to 62 years were enrolled in the study. Inflammation of the maxillary sinus was considered when the Schneider membrane was thicker than 2 mm. Statistical analyses were performed with Statistica 12 by StatSoft and StatXact by Cytel using the Shapiro–Wilk test, Student's t-test, and the Mann–Whitney test.
Results Out of 12 comparisons between variables, only 3 comparisons were significant. There was a relationship between the treatment effect (reduction in maxillary sinus inflammation 3 months after treatment) and the maximum height of the Schneider membrane (p = 0.004). There was a relationship between the presence of a periapical lesion and the minimum height of the Schneider diaphragm (p = 0.02), and there was a relationship between the presence of a periapical lesion and the maximum height of the Schneider diaphragm (p = 0.04).
Conclusion Primary and secondary root canal treatments of maxillary premolars and molars reduce the inflammation of the maxillary sinus 3 months after treatment.

Published: March 2022

ResumoA fratura de Hoffa (FH) é típica do côndilo femoral posterior no plano sagital, com incidência estimada de 0,65% nas fraturas do fêmur. De modo geral, a FH é observada no côndilo femoral lateral em traumatismos de alta energia, com força de carga axial sobre o terço distal do fêmur e o joelho em mais de 90° de flexão. O caso aqui relatado ocorreu em um paciente com FH medial complexa e luxação de joelho após um traumatismo de alta energia. Em dois anos de acompanhamento, a análise radiológica revelou consolidação óssea completa e integração do aloenxerto. O transplante de aloenxerto osteocondral deve ser considerado em casos de FH complexa, e visa restaurar a anatomia superfície articular para evitar o desenvolvimento de osteoartrose pós-traumática precoce em pacientes jovens.
Damsels in distress: gender and negative place branding
Authors: Durrani Sameera 
Published: March 2022

AbstractThis article provides a historical perspective on how institutionalized articulations of gender in visual news narratives may contribute towards the erosion of a country’s soft power potential. It analyses thirty years of photographic coverage given by an elite western publication, Time magazine to women from two countries with problematic place brands: Iran and Pakistan. This study documents how iterative longitudinal patterns of visual grammar contribute towards the layered marginalization of women within narratives. Women are much less visible in terms of image frequency, with selective value placed on certain kinds of female subjects across the decades, choices often shaped by stereotypes as well as foreign policy preferences. For Iranian women, the visual discourse empowers women resisting conservative forces, and valorizes trailblazers redefining the public space. For Pakistani women, a narrative showcasing political activism devolves into one highlighting victims/activists in the context of gender-based discrimination. The choice of ‘valuable’ bodies in both instances, expressed with the help of quantifiable semiotic trends in camera angles, shot and gaze, is imbued with indirect judgment of the political leadership and cultural and socio-political systems of the countries themselves. In both cases, the overall narrative is of a system pre-disposed to oppress women, thus negatively juxtaposing the ‘people’ aspect of the Anholt Nation Brand Index against the elements of governance, culture and heritage, to the overall detriment of both place brands.
RETRACTED ARTICLE: Procedural necessity in primary investigation work
Authors: Moussa Ahmad Fekry , Al Qatawneh Ibrahim Suleiman , Kandeel Moustafa Elmetwaly 
Published: March 2022

AbstractThis study focuses on the procedural necessity of primary investigations, since necessity is a common legal term and constitutes a theory in some branches of law. Procedural necessity has sparked controversy and debate about its legitimacy, and its subjectivity in the criminal procedure law in many Arab countries in the preliminary investigation work. Defining its scope, conditions, and nature can be especially challenging. This study shows the position of the Arab procedural legislation and judiciary systems regarding procedural necessity in the primary investigation work in various legal systems, especially in Egypt. Based on the assessment of the existing legislative regulation in Arab countries, the study gives grounds to talk about the inadmissibility of expanding the discretionary powers of the authorities associated with circumstances excluding the crime of an act, as this can create preconditions for abuse of officials and limit the existing individual rights and freedoms of citizens.
Morphophonological activation in Chinese word recognition
Authors: Tsang Yiu-Kei 
Published: March 2022

Abstract
The role of morphophonology during Chinese visual word recognition was investigated in three masked priming lexical decision experiments. The primes and targets were Cantonese Chinese bimorphemic words. In Chinese, most characters correspond to morphemes, but sometimes the mapping between character and morpheme is not one-to-one. Specifically, some characters are heteronymic, which had one visual form associated with multiple pronunciations and meanings (e.g., “長” is pronounced as /coeng4/ and /zoeng2/ in Cantonese, which means “long” and “senior”, respectively). In Experiment 1, facilitative priming was found when the primes and targets shared heteronymic characters of identical (e.g., “長遠-long term” /coeng4jyun5/ and “長短-length” /coeng4dyun2/), but not a different, pronunciation (e.g., “長官-senior official” /zoeng2gun1/). Sharing word-level phonology only (e.g., “場景-scene” /coeng4ging2/) had no effects. Experiment 2 replicated Experiment 1, and further indicated that the effects could not be attributed to sharing word-level meanings (e.g., “即時-immediate” /zik1si4/). Experiment 3 compared the priming effects produced by the two alternative pronunciations of the heteronymic characters. The results showed that the strength of priming was statistically comparable in the two pronunciation-congruent conditions. Together, this study provided evidence that morphophonology was activated to facilitate the ambiguity resolution of heteronymic characters. The lemma model was modified to accommodate the results.

Published: March 2022

Abstract
Since the successful isolation of graphene in 2004, two-dimensional (2D) materials have become one of the focuses in material science owing to their extraordinary physical and chemical properties. In particular, 2D group VA elemental materials exhibit fascinating thickness-dependent band structures. Unfortunately, the well-known instability issue hinders their fundamental researches and practical applications. In this review, we first discuss the degradation mechanism of black phosphorus (BP), a most studied group VA material. Next, we summarize the methods to enhance BP stability with the focus of multifunctional passivation. Finally, we briefly discuss the protection strategies of other emerging group VA materials in recent years. This review provides insight for the degradation mechanism and protecting strategy for 2D group VA elements materials, which will promote their potential applications in electronics, optoelectronics, and biomedicine.
A machine learning approach to determine bubble sizes in foam at a transparent wall
Authors: Knüpfer Leon , Heitkam Sascha 
Published: March 2022

Abstract
This article describes the use of a machine learning based technique to measure the bubble sizes of foam with polyhedral bubble shape in contact with a transparent wall. For two different experimental cases images are obtained of foam in a cylindrical column and labeled with a classical image processing algorithm. An available neural network based model, initially designed for cell image applications, is trained and validated to segment the images. When comparing the bubble size distribution in images found using the trained model with manually segmented images a good agreement over a large range of diameters can be found. The error of the mean diameter in both cases lies below

Published: March 2022

Abstract
Clean water is vital for healthy ecosystems, for human life and, in a broader sense, it is directly linked to our socio-economic development. Nevertheless, climate change, pollution and increasing world population will likely make clean water scarcer in the near future. Consequently, it becomes imperative to develop novel materials and more efficient ways of treating waste and contaminated water. Carbon nanotube (CNT) sponges, for example, are excellent in removing oleophilic contaminants; however, due to their super-hydrophobic nature, they are not as efficient when it comes to absorbing water-soluble substances. Here, by means of a scalable method consisting of simply treating CNT sponges at mild temperatures in air, we attach oxygen-containing functional groups to the CNT surface. The functionalized sponge becomes hydrophilic while preserving its micro- and macro-structure and can therefore be used to successfully remove toxic contaminants, such as pesticides, that are dissolved in water. This discovery expands the current range of applications of CNT sponges to those fields in which a hydrophilic character of the sponge is more suitable.
Tetrahedral W4 cluster confined in graphene-like C2N enables electrocatalytic nitrogen reduction from theoretical perspective
Authors: Zhang Jin , Fang Cong , Li Yang , An Wei 
Published: March 2022

Abstract
Exploring the format of active site is essential to further the understanding of an electrocatalyst working under ambient conditions. Herein, we present a DFT study of electrocatalytic nitrogen reduction (eNRR) on W4 tetrahedron embedded in graphene-like C2N (denoted as W4@C2N). Our results demonstrate that N-affinity of active sites on W4 dominate over single-atom site, rendering *NH2 + (H+ + e−) →*NH3 invariably the potential-determining step (PDS) of eNRR via consecutive or distal route (U
L = −0.68 V) to ammonia formation. However, *NHNH2 + (H+ + e−) →*NH2NH2 has become the PDS (U
L = −0.54 V) via enzymatic route towards NH2NH2 formation and thereafter desorption, making W4@C2N a potentially promising catalyst for hydrazine production from eNRR. Furthermore, eNRR is competitive with hydrogen evolution reaction (U
L = −0.78 V) on W4@C2N, which demonstrated sufficient thermal stability and electric property for electrode application.

Published: March 2022

Abstract
With the increasing applications of Lithium-ion batteries in heavy equipment and engineering machinery, the requirements of rate capability are continuously growing. The high-rate performance of Li4Ti5O12 (LTO) needs to be further improved. In this paper, we synthesized LTO microsphere-TiO2(B) nanosheets (LTO-TOB) composite by using a solvothermal method and subsequent calcination. LTO-TOB composite combines the merits of TiO2(B) and LTO, resulting in excellent high-rate capability (144.8, 139.3 and 124.4 mAh g−1 at 20 C, 30 C and 50 C) and superior cycling stability (98.9% capability retention after 500 cycles at 5 C). Its excellent electrochemical properties root in the large surface area, high grain-boundary density and pseudocapacitive effect of LTO-TOB. This work reveals that LTO-TOB composite can be a potential anode for high power and energy density lithium-ion batteries.
Understanding the electromagnetic topology during the ohmic breakdown in tokamaks considering self-generated electric fields
Authors: Yoo Min-Gu , Na Yong-Su 
Published: March 2022

Abstract
The physical mechanisms of the ohmic breakdown in a tokamak have been understood based on the classical Townsend avalanche theory. However, a new systematic theory (Yoo et al 2018 Nat. Commun.
9 3523) recently demonstrated that electron avalanches during the ohmic breakdown are completely different from the Townsend avalanche due to strong self-generated electric fields. In this study, we elucidate the multi-dimensional effects of the self-generated electric field on plasma dynamics during the ohmic breakdown. We also propose a novel electromagnetic topology analysis method that can easily predict the overall plasma behavior and where the main plasma is generated. The topology analysis method is validated by a state-of-art particle simulation for various magnetic configurations. New physical insights into the complex electromagnetic topology would facilitate designing more reliable and optimized ohmic breakdown scenarios in future tokamaks, such as ITER and beyond.
An ultra-thin flexible conformal four-band metamaterial absorber applied in S-/C-/X-band
Authors: Luo Zhiyou , Ji Shijun , Zhao Ji , Liu Zhenze , Dai Handa 
Published: March 2022

Abstract
In recent years, many kinds of multiband metamaterial absorbers (MMAs) have sprung up. However, most of their dielectric layers were filled with rigid dielectric materials, which has many limitations in practical application. In this paper, an ultra-thin flexible conformal four-band metamaterial absorber (FMMA) is presented based on the dielectric material of polyimide (PI), and its thickness is only 0.0047 of the wavelength at the lowest absorption frequency. The top resonator is adopted a hollow structure, which is different from the common strip and ring structure, providing a novel idea for multiband absorber design. The proposed FMMA achieved four absorption peaks with an absorptivity higher than 90% from S-band to X-band. Meanwhile, in both TE and TM modes, it is insensitive to polarized waves and maintains good absorption under a wide incident angle. The experiment is carried out to demonstrate that the FMMA has satisfactory absorption performance. Due to its flexible conformal characteristic and good absorption performance, the FMMA can be applied in electromagnetic shielding of a curved surface, meteorological satellite, and radar detection.
On the role of Zn doping on tuning the electronic and optical properties of MnCr2O4 spinel via Mn0.5Zn0.5Cr2O4 doping scheme: A first-principles quantum computational analysis

Abstract
Herein, we report on the impact of Zn doping on electronic and optical properties of manganese di-chromium oxide spinel MnCr2O4 via Mn0.5Zn0.5Cr2O4 doping scheme. For the quantum computational analysis on the targeted properties, we employed first-principles density functional theory approach within full-potential linearized augmented plane wave method by Modified Becke–Johnson potential. The calculated partial and total density of states revealed a strong hybridization among electronic orbitals of the constituent species while the asymmetric spin-polarized profiles of density of states showed magnetic nature of the spinels. The major interspecies spin interaction in the degenerate valence band is via (Mn

) from −7 eV to Fermi level for spin up polarization. Interestingly, we predict a reduction in band gap of MnCr2O4 to order 1eV subjected to the Zn doping, which considerably modified the electronic and optical properties of the doped spinels Mn0.5Zn0.5Cr2O4 in contrast to its undoped counterpart. In particular, we predict an enhancement in absorption coefficient, energy loss function, reflectivity, dielectric constant and refractive index for Mn0.5Zn0.5Cr2O4 spinels at some regions of ultraviolet energy spectrum. The calculated static refractive index of MnCr2O4 is 1.59 and for Mn0.5Zn0.5Cr2O4 it is 1.4. The optoelectronic properties indicate the promising prospects of the Zn-doped spinels for potential application in optoelectronic devices.
Magnetic correction to the anomalous magnetic moment of electrons
Authors: Lin Fan , Huang Mei 
Published: March 2022

Abstract
We investigate the leading order correction of anomalous magnetic moment (AMM) to electrons in a weak magnetic field and find that the magnetic correction is negative and magnetic field dependent, indicating a magnetic catalysis effect for the electron gas. In the laboratory, to measure the g − 2, the magnitude of the magnetic field B is several T, and correspondingly the magnetic correction to the AMM of electron/muon is around 10−34/10−42, therefore the magnetic correction can be safely neglected in the current measurement. However, when the magnitude of the magnetic field strength is comparable with the electron mass, the magnetic correction of the electron’s AMM will become considerable. This general magnetic correction to the charged fermion’s AMM can be extended to study quantum chromodynamic matter under a strong magnetic field.
