Some complications of the transitive society in the sphere of legal education
Authors: Kovaleva Anastasia , Rodina Victoria , Volkonskaya Olga
Published: November 2019

A transitive society is a special stage of its development, which is influenced by various factors that ultimately affect the direction of development of the society, whether it is positive or negative, will move to a new higher stage of development or an irreversible process of degradation will begin. The transition period in Russia has its own peculiarities, largely due to the original historical path and profound transformations that took place one after another for a long period. However, the formation of these institutions is impossible without legal education, the highest degree of which provides access to higher legal education. The aim of this research is to make an objective assessment of the situation in the system of higher legal education, to analyse its problem areas and to assess their impact without overcoming the transitional period of State development.
Problems of legal regulation of grant support for fundamental research in the Russian Federation
Authors: Sapozhnikova Ekaterina , Sivolapenko Elena
Published: November 2019

The development of science-intensive industry and the availability of a system to support scientific activities today occupy a key place in the policy of any strong and independent state. In recent years, grants have become a priority in the formation of sources of funding for research and innovation in various fields. In accordance with the strategy of innovative development for the period up to 2020 the procedure of improvement of the legislation of the Russian Federation providing legal regulation of grant support of scientific activity is carried out in Russia. However, the process of improving Russian legislation in the field of research funding has not yet been completed. The main problems today are the uncertainty of the legal regime of the grant in the Russian legislation, the lack of a clear mechanism governing the relationship of grant-givers, grantees and procedures for the provision of scientific grants, as well as the imperfection of tax legislation on the taxation of grants.

Authors: Fegert Joerg , Freyberger Harald Jürgen
Published: November 2019

Der vorliegende Text betrachtet Posttraumatische Belastungsstörungen und Traumafolgestörungen in der Adoleszenz und geht dabei insbesondere auf die Transitionsproblematik ein. Zum einen bilden sich auf der diagnostischen Ebene die Traumatisierungen häufig nicht PTBS-spezifisch, sondern in Selbsthilfe und Selbstmedikationsmaßnahmen sowie Alkohol- und Drogenabhängigkeit und Dissozialität ab, die im erwachsenenpsychiatrischen System oft nicht ausreichend hinterfragt werden. Zum anderen geht es um die Weiterentwicklung und Implementierung traumapädagogischer Ansätze insbesondere für Jugendliche, die in kritischen Hochrisikokonstellationen aufwachsen oder sich bereits Institutionen der Jugendhilfe oder der Eingliederungshilfe befinden. Hier wird nicht nur ein eklatanter Mangel in der Aus-, Fort- und Weiterbildung der beteiligten Berufsgruppen, sondern auch im Hinblick auf empirische Therapiestudien festgestellt.

Published: November 2019

The purpose of this study was to compare measures of bilateral shoulder and hip range of motion (ROM) between youth softball pitchers and position players. Fifty-two youth softball athletes (12.7±2.1 yrs.; 160.28±10.98 cm; 59.31±15.07 kg) participated. Bilateral hip and shoulder ROM were measured among pitchers (n=29) and position players (n=23). A 2 (pitcher/position player) × 2 (dominant/non-dominant) ANOVA was performed for both internal and external rotation ROM for the shoulder and hip. Paired sample t-tests were also conducted to examine side-to-side differences in total ROM. Data revealed a significant interaction between position and side dominance. Specifically, position players have significantly more non-dominant shoulder external rotation ROM (106.92°± 9.14°) than pitchers (100.12°± 11.21°). There were no significant differences between throwing and non-throwing sides. It is important that coaches and clinicians are aware of these adaptations between overhand and underhand throwing in order to properly develop conditioning and rehabilitation programs to alleviate injury susceptibility and cater to position-specific demands. Additionally, the current data suggest many of the functional adaptations seen within older populations are not fully developed until after youth.
Hormontherapie bei Hodenhochstand
Authors: Reschke Felix
Published: November 2019

Der Hodenhochstand stellt eine sehr häufige angeborene Normvariante des Urogenitaltrakts dar. Dabei ist bekannt, dass infolge der Fehllage des Hodens seine normale Entwicklung eingeschränkt sein kann. Eine Folge daraus ist ein erhöhtes Entartungsrisiko sowie eine verminderte Spermiogenese und Fertilität. Zwischen den verschiedenen Fachrichtungen besteht internationaler Konsens darüber, dass die Behandlung des maldeszendierten Hodens spätestens zum ersten Geburtstag abgeschlossen sein sollte. Gemäß der deutschen AWMF-Leitlinie soll die hormonelle Therapie Patienten mit beidseitigem Hodenhochstand angeboten werden. Der nachfolgende Artikel wird die Rationale hinter dieser Empfehlung unter Einbezug der aktuellen Literatur erörtern.
Das Licht am Ende des Tunnels
Authors: Hardinghaus Christian
Published: November 2019

Den meisten Menschen, die in der Notfallmedizin arbeiten, wird der Begriff Nahtoderfahrungen irgendwann schon einmal untergekommen sein. Die Wahrscheinlichkeit, dass ein klinisch toter Patient, der wieder zurückgeholt wurde, dem Operateur von wissenschaftlich nicht erklärbaren Phänomenen erzählt, ist hoch. So berichten etwa 20 % aller Menschen, die einen Herzstillstand überlebt haben, von Nahtoderlebnissen. Während die Neurowissenschaften um Erklärungen bemüht sind und eine nachgewiesene, bleibende Hirnaktivität nach dem Herzstillstand dafür für verantwortlich sehen, so ist damit nicht erklärbar, warum sich all die vielen Nahtoderfahrungen so ähneln. Fast alle Betroffenen berichten von außerkörperlichen Erfahrungen, während dieser ihre Seele den toten Körper verlässt, sie und ihre Umwelt aber dennoch mit allen Sinnen weiter erleben können. Mehr als die Hälfte schildert ein helles, weißen Licht, auf das sie sich, oft durch einen Tunnel, zubewegt und bis zu ein Drittel erzählt von Kontakt mit dem Jenseits, beispielsweise von Treffen oder Gespräche mit bereits verstorbenen Verwandten oder Freunden.

Authors: Thomas Sonali , Sinha DN , Singh AK , Deopa Deepa , Niranjan Richa
Published: November 2019

Background and Aims: Spleen is the largest secondary lymphatic organ. It acts as a graveyard for RBCs, is essential for immune responses, performs lymphopoiesis in adults and haemopoiesis in fetuses. The present study was conducted to assess the histogenesis of spleen in human fetuses in view of existing literature. Material and Methods: The study was carried out on 34 formalin preserved human fetuses procured from Dr Sushila Tiwari Government Hospital, Haldwani with due clearance from ethical committee. The 6 pm sections of the spleen were stained with Haematoxylin and Eosin and observed under light microscope. Results: At 14 tol5 weeks, spleen had extensive sinusoids filled with RBCs and few lymphocytes. At 16-18 weeks, trabecular arteries were noticed more towards centre along with extensive haemopoietic cells in the venous sinusoids. By 20th week lymphocytic aggregation had started around arterioles. By 24 weeks periarteriolar lymphatic sheath was clearly observed. At term (37-40 weeks), classical primary lymphoid follicle was present but germinal centers were not observed. Conclusion: During earlier differentiation, spleen symbolizes the function of haemopoietic activities and gradually during subsequent gestation; it establishes its identity as a principle lymphoid tissue.

Published: November 2019

Epilepsy is often associated with psychosocial comorbidity and this can be more disabling than the seizure activity. Still, these associated conditions are often underdiagnosed and therefore not sufficiently treated. We studied a large pediatric cohort of 371 patients with epilepsy to identify factors associated with negative outcome. We found that patients with early-onset epilepsy, epilepsy of known etiology, and polypharmacy were the most likely to display cognitive impairment. Behavioral problems were particularly prevalent in patients with an epilepsy duration ≥ 5 years. Similarly, early-onset epilepsy, long illness duration, epilepsy of known etiology, and polypharmacy had an adverse effect on school placement and/or social contact. With polypharmacy being the only potentially modifiable factor, it is important to balance between benefits and adverse effects of antiepileptic drugs and consider alternative therapy options in selected patients such as epilepsy surgery, vagal nerve stimulation, and ketogenic diet early-on.

Authors: Smith Michele E. , Wilson Patrick T.
Published: November 2019

The role of human rhinovirus/enterovirus (HRV/HEV) in severe lower respiratory tract infections remains unclear. We characterized the respiratory status of children admitted to a large academic pediatric intensive care unit (PICU) who tested positive for only HRV/HEV. One hundred and fifty-five children met inclusion criteria with 62% requiring positive pressure respiratory support of 5 cm of water pressure or more within the first 24 hours of admission. Among them, 34% had SaO2 to FiO2 ratios of 264 or less with 22 patients (14%) meeting criteria for pediatric acute respiratory distress syndrome. HRV/HEV is associated with significant respiratory disease in children admitted to the PICU.
Structural relaxation of nanocrystalline PdAu alloy: Probing the spectrum of potential barriers
Authors: Deckarm Michael Johannes , Braun Christian , Birringer Rainer
Published: November 2019

A commonality between nanocrystalline metals and metallic glasses is their dependence of structure and properties upon preparation history and postprocessing. Depending on preparation conditions, stored excess enthalpy and volume—relative to the crystalline ground state—can vary significantly. Annealing of material states of elevated enthalpy or volume induces structural relaxation and concomitant depletion of excess energy and volume. We analyzed the kinetics of volume relaxation in nanocrystalline PdAu alloys by partitioning the overall process into a set of independent and parallel reactions for arbitrary time-temperature protocols. The obtained spectra of kinetic parameters imply a complex relaxation behavior that violates time-temperature superposition and time aging-time superposition. The analysis will enable to reconstruct the effective energy landscape underlying the relaxation dynamics.

Published: November 2019

Acoustic metasurfaces have largely been explored for acoustic field modulation, but because of their structural complexity, they are mainly implemented for airborne low frequency sound and generally located in the transmission medium, acting as a “passive acoustic field modulator.” In this work, we present numerically the acoustic field modulation in water with a metasurface lens which consists of typical space-coiling structure units at high frequency (≥1 MHz). Four kinds of materials with different physical properties were utilized as lens materials, and the lens was set at the front surface of the ultrasonic transducers, acting as an “active acoustic field modulator.” The proposed investigation could be extended to allow the metasurface lens for numerous waterborne high frequency ultrasound applications.

Published: November 2019

It has been increasingly recognized that preservation and public accessibility of primary experimental data are cornerstones necessary for the reproducibility of empirical sciences. In the field of molecular crystallography, many journals now recommend that authors of manuscripts presenting a new crystal structure should deposit their primary experimental data (X-ray diffraction images) to one of the dedicated resources created in recent years. Here, we describe our experiences developing the Integrated Resource for Reproducibility in Molecular Crystallography (IRRMC) and describe several examples of a crucial role that diffraction data can play in improving previously determined protein structures. In its first four years, several hundred crystallographers have deposited data from over 5200 diffraction experiments performed at over 60 different synchrotron beamlines or home sources all over the world. In addition to improving the resource and curating submitted data, we have been building a pipeline for extraction or, in some cases, reconstruction of the metadata necessary for seamless automated processing. Preliminary analysis indicates that about 95% of the archived data can be automatically reprocessed. A high rate of reprocessing success shows the feasibility of using the automated metadata extraction and automated processing as a validation step for the deposition of raw diffraction images. The IRRMC is guided by the Findable, Accessible, Interoperable, and Reusable data management principles.

Neutrophil dysregulation is implicated in the pathogenesis of systemic lupus erythematosus (SLE). SLE is characterized by elevated levels of a pathogenic neutrophil subset known as low-density granulocytes (LDGs). The origin and phenotypic, functional, and pathogenic heterogeneity of LDGs remain to be systematically determined. Transcriptomics and epigenetic assessment of lupus LDGs, autologous normal-density neutrophils, and healthy control neutrophils was performed by bulk and single-cell RNA sequencing and assay for transposase-accessible chromatin sequencing. Functional readouts were compared among neutrophil subsets. SLE LDGs display significant transcriptional and epigenetic heterogeneity and comprise 2 subpopulations of intermediate-mature and immature neutrophils, with different degrees of chromatin accessibility and differences in transcription factor motif analysis. Differences in neutrophil extracellular trap (NET) formation, oxidized mitochondrial DNA release, chemotaxis, phagocytosis, degranulation, ability to harm the endothelium, and responses to type I interferon (IFN) stimulation are evident among LDG subsets. Compared with other immune cell subsets, LDGs display the highest expression of IFN-inducible genes. Distinct LDG subsets correlate with specific clinical features of lupus and with the presence and severity of coronary artery disease. Phenotypic, functional, and pathogenic neutrophil heterogeneity are prevalent in SLE and may promote immune dysregulation and prominent vascular damage characteristic of this disease.
Geometrical reorganization of Dectin-1 and TLR2 on single phagosomes alters their synergistic immune signaling
Authors: Li Wenqian , Yan Jun , Yu Yan
Published: November 2019

Receptors of innate immune cells function synergistically to detect pathogens and elicit appropriate immune responses. Many receptor pairs also appear “colocalized” on the membranes of phagosomes, the intracellular compartments for pathogen ingestion. However, the nature of the seemingly receptor colocalization and the role it plays in immune regulation are unclear, due to the inaccessibility of intracellular phagocytic receptors. Here, we report a geometric manipulation technique to directly probe the role of phagocytic receptor “colocalization” in innate immune regulation. Using particles with spatially patterned ligands as phagocytic targets, we can decouple the receptor pair, Dectin-1 and Toll-like receptor (TLR)2, to opposite sides on a single phagosome or bring them into nanoscale proximity without changing the overall membrane composition. We show that Dectin-1 enhances immune responses triggered predominantly by TLR2 when their centroid-to-centroid proximity is <500 nm, but this signaling synergy diminishes upon receptor segregation beyond this threshold distance. Our results demonstrate that nanoscale proximity, not necessarily colocalization, between Dectin-1 and TLR2 is required for their synergistic regulation of macrophage immune responses. This study elucidates the relationship between the spatial organization of phagocytic receptors and innate immune responses. It showcases a technique that allows spatial manipulation of receptors and their signal cross-talk on phagosomes inside living cells.
The socialisation of interactional rituals
Authors: Kádár Dániel Z. , Szalai Andrea
Published: November 2019

The present paper examines the ways in which ritual cursing operates as a form of teasing in (Gabor) Roma communities. By ‘ritual cursing’ we mean forms of curse that are believed to cause harm to the cursed person or people related to them, i.e. cursing studied here differs from swearing and ‘cussing’, as it embodies supernatural beliefs to a degree. While cursing is an archetype of ritual, to date little pragmatic research has been done on this phenomenon, supposedly due to the scarcity of interactional data collected in cultures where cursing is actively practised; thus, the present paper fills a knowledge gap in the field. We examine cursing in interactions where it is used as teasing in order to socialise young children. Since ritual is a means through which social structures are re-created (Durkheim 1912 [1954/2001]), aiding young language users to acquire rituals is a key aspect of community life. However, little research has been done on the ways in which ritual practices are socialised in communities at the level of interaction, which validates our focus on teasing curses. The phenomenon studied is also relevant to previous sociopragmatic research on teasing: whilst in other (non-ritual) sociocultural settings socialising teasing implies aiding young language users to distinguish between humour and offence, due to the potential harm attributed to ritual cursing its socialisation is centred both on harm and the offence in the conventional sense of the word.
Critical Scaling Behaviors of Entanglement Spectra*
Authors: Tang Qi-Cheng , Zhu Wei
Published: November 2019

We investigate the evolution of entanglement spectra under a global quantum quench from a short-range correlated state to the quantum critical point. Motivated by the conformal mapping, we find that the dynamical entanglement spectra demonstrate distinct finite-size scaling behaviors from the static case. As a prototypical example, we compute real-time dynamics of the entanglement spectra of a one-dimensional transverse-field Ising chain. Numerical simulation confirms that the entanglement spectra scale with the subsystem size l as ∼l
−1 for the dynamical equilibrium state, much faster than ∝ ln−1
l for the critical ground state. In particular, as a byproduct, the entanglement spectra at the long time limit faithfully gives universal tower structure of underlying Ising criticality, which shows the emergence of operator-state correspondence in the quantum dynamics.
Controllable high-speed polariton waves in a PT-symmetric lattice
Authors: Ma Xuekai , Kartashov Yaroslav Y , Gao Tingge , Schumacher Stefan
Published: November 2019

Parity-time (PT) symmetry gives rise to unusual phenomena in many physical systems, presently attracting a lot of attention. One essential and non-trivial task is the fabrication and design of the PT-symmetric lattices in different systems. Here we introduce a method to realize such a lattice in an exciton-polariton condensate in a planar semiconductor microcavity. We theoretically demonstrate that in the regime, where lattice profile is nearly PT-symmetric, a polariton wave can propagate at very high velocity resulting from the beating of a ground state condensate created in the lowest energy band at very small momentum and a condensate simultaneously created in higher energy states with large momentum. The spontaneous excitation of these two states in the nonlinear regime due to competition between multiple eigenmodes becomes possible since the spectrum of nearly PT-symmetric structure reveals practically identical amplification for Bloch waves from the entire Brillouin zone. There exists a wide velocity range for the resulting polariton wave. This velocity can be controlled by an additional coherent pulse carrying a specific momentum. We also discuss the breakup of the PT-symmetry when the polariton lifetime exceeds a certain threshold value.
Ultrafast dynamics of 4f electron spins in TbFeCo film driven by inter-atomic 3d–5d–4f exchange coupling
Authors: Chen Zhifeng , Li Shufa , Zhou Shiming , Lai Tianshu
Published: November 2019

The ultrafast demagnetization dynamics of 3d and 4f spins, respectively, in FeCo and Tb of TbFeCo alloy film are studied independently by employing a dual-color time-resolved magneto-optical Kerr spectroscopy. The demagnetization dynamics of 3d and 4f spins are independently probed, respectively, by 800 and 400 nm light. Two-step demagnetization dynamics are observed for both the 3d and 4f spins under the excitation of 800 nm laser. In particular, the onset of 4f spin dynamics presents a delayed time with respect to the one of 3d spin dynamics. Those results clearly reveal a strong inter-atomic 3d–5d–4f exchange coupling which drives the first-step subpicosecond ultrafast demagnetization process of 4f spins, and a spin(4f)-lattice coupling which drives the second-step slower demagnetization process of 4f spins. A numerical calculation based on four temperature model reproduces the coupling characteristics in the demagnetization dynamics, and reveals the energy evolution dynamics among the different subsystems. These results provide a direct demonstration of strong coupling dynamics between the two spin subsystems in rare earth-transition metal alloy occurring within subpicosecond timescale, and show a new approach for ultrafast control of 4f spins via an indirect excitation.
Spin-valley system in a gated MoS2-monolayer quantum dot
Authors: Pawłowski J
Published: November 2019

The aim of presented research is to design a nanodevice based on a gate-defined quantum dot within a MoS2 monolayer in which we confine a single electron. By applying control voltages to the device gates we modulate the confinement potential and force intervalley transitions. The present Rashba spin–orbit coupling additionally allows for spin operations. Moreover, both effects enable the spin-valley SWAP. The device structure is modeled realistically, taking into account feasible dot-forming potential and electric field that controls the Rasha coupling. Therefore, by performing reliable numerical simulations, we show how by electrically controlling the state of the electron in the device, we can obtain single- and two-qubit gates in a spin-valley two-qubit system. Through simulations we investigate possibility of implementation of two qubits locally, based on single electron, with an intriguing feature that two-qubit gates are easier to realize than single ones.

In this study, we compared the effect of the isospin asymmetry of proton and neutron density distributions in the neutron skin-type (NST) case and in the Hartree-Fock formalism (HF) on the half-life of alpha emitters with the atomic number in the range of

. The NST case and HF formalism based on the Skyrme-SLy4 effective interaction reveal different isospin asymmetries for selected alpha emitters. Furthermore, the obtained results reveal an increase in the α-decay widths of about 30% for the NST case in comparison with the equivalent values obtained by HF formalism. The standard deviations for calculated half-lives within the NST case and HF formalism are about 0.438 and 0.391, respectively.

Published: November 2019

This study aims to investigate the effect of UV C irradiation on the secondary metabolites profile and the antioxidant activity of brown rice during two days germination. The change on the metabolite profile was identified using UPLC-ESI-QTOF, while antioxidant activity was performed using DPPH assay. The UPLC-ESI-QTOF chromatogram showed that three new peaks were found only in the germinated brown rice (GBR) that was irradiated by UV C. Based on the mass spectroscopy data, one of those three compounds was tentatively identified as glycosylated flavonoid, while the rest remained undetermined. The antioxidant activity of brown rice increased after two days germination, whilst there were no differences between antioxidant activities of germinated brown rice with UV C irradiation and that of without UV C irradiation.

An andesite rock sample was taken from potential geothermal area on Lili-Sepporaki, west Sulawesi. The sample is an impermeable cap rock with a high silica mineral at alteration zone around a manifestation. Its Three-dimensional rock structure was analyzed to see its deformation due to temperature change. Change of temperature from 24˚C to 100˚C, 150˚C, 200˚C, and 250˚C was applied to the sample. Subsequent to each change of temperature, the sample was scanned using a micro-Computed Tomography Scan (μ-CT Scan). From the scanning process, a sub-volume 300 pixels were reconstructed, and its 3D pore and mineral structure were characterized. It is found that porosity {φ (T)}, specific surface area {SsA (T)} decrease polynomial for pore structure and increase polynomial as temperature increases. This result show that as temperature increases the volume of mineral is bigger make the pore volume smaller. The Fractal dimension for pore structure (2.65 ± 0.02) and for mineral structure (2.89 ± 0.015).

The natural resources of oil and gas potential in the West Papua waters constitute a significant expansion of oil and gas investments in Indonesia’s maritime specifically the eastern region. South Aru is located at the eastern edge of the basin trough Aru and includes one of the most potential oil and gas basins. Complex geological structures such as the case of large dip make seismic cross section results do not represent the subsurface structure of the earth nearing the actual subsurface geological conditions. The working principle of Kirchhoff prestack time migration is looking for reflector positions using delay time of wave energy reflection to get a better seismic section on the tilted reflector with less diffraction effect and have little effect arch (smiling effect) which generates seismic section that can represent the subsurface structure of the earth. Reflectivity cross section of generally more clearly observed after the migration process is carried out so that the resolution of cross section seismic better, which can be useful as the data is ready to be interpreted as the purposes of determination prospects of natural resources, especially regarding the hydrocarbon potential of the South Aru, West Papua waters.

The Shift is the displacement of the object’s position from its initial state to its final state. Shifting phenomena can be found in landslides, cracks in building construction, or bridges. One of the sensors used to detect deflection is the GMR sensor. The GMR sensor is a sensor that can detect changes in magnetic fields. The configuration of permanent magnets and GMR sensors can be used to detect micro-order shifts. This research was conducted in several stages, namely making a bridge model, making a sensor circuit, signal conditioning circuit and testing characteristics. The research method is to place a permanent magnet on the static and GMR sensors on the part that is easily shifted on the bridge. The test results show that the GMR sensor can detect shifts in the 10micro order and the sensitivity of the GMR sensor can be obtained at 0.0131 Volt / mm. The voltage response of the GMR sensor to shift distance is exponential. The maximum shift test is obtained at half the bridge span. This research can be used for monitoring bridge shifts.
