Published: August 2022

Abstract
The article addresses Solution-Oriented Questions (SOQs) as an interactional practice
for relationship management in psychodiagnostic interviews. Therapeutic alliance results from the concordance of alignment, as
willingness to cooperate regarding common goals, and of affiliation, as relationship based upon trust. SOQs particularly allow
for both: They are situated at the end of a troublesome topic area, which is linked to low agency on the patient’s side, and
they reveal understanding of and interest in the patient. Following the paradigm of Conversation Analysis and German Gesprächsanalyse this paper analyzes the design and functions of SOQs as a means for securing and
enhancing the relationship in the process of therapy. Our data comprise 15 videotaped first interviews following the manual of
the Operationalized Psychodynamic Diagnostics. The analyses refer to all SOQs found but will be illustrated by means of a
single conversation.

Abstract
The hands of nuclear medicine (NM) personnel involved in radiopharmaceutical preparation and administration can receive significant radiation doses. The dose distribution across the hand is nonuniform and the Hp(0.07) doses obtained by an individual passive ring dosimeter do not always present a real situation. The aim of this study was to assess the extremity exposure of NM workers working with 99mTc-labelled radiopharmaceuticals and with an automatic IRIDE (COMECER, Italy) 18F-FDG injection system. Hp(0.07) doses were measured using calibrated thermoluminescent dosimeters-100 (TLD-100) and were read by a RIALTO TLD (NE Technology) reader. It was found that the most exposed parts of the hand during work with 18F and 99mTc radionuclides are the fingertips of the thumb, index finger and middle finger. The maximum fingertip doses were 1.3–2.4 times higher compared with the doses from the typical monitoring position (base of the middle finger of the dominant hand). When working with 99mTc, the average hand doses were relatively high, i.e. 0.17 ± 0.04 and 0.37 ± 0.13 mSv Gbq−1 for the left and the right hand, respectively, during preparation, and 58 ± 20 and 53 ± 13 µSv GBq−1 for the left and the right hand, respectively, during administration of 99mTc labelled radiopharmaceuticals. Meanwhile, the lowest doses were found for hands during administration of 18F-FDG (average hand dose 28 ± 13 µSv GBq−1 for the left hand and 28 ± 7 µSv GBq−1 for the right hand), which shows the advantages of automated injection/infusion systems, thus implementation of automatic infusion/injection in hospitals could be an expedient way to optimize Hp(0.07) doses to NM workers.
Improved analog performance of FDSOI based NCFET with a ferroelectric–paraelectric–dielectric gate stack

Abstract
With the superior analog/RF performance of planar device architectures such as fully depleted silicon-on-insulator (FDSOI) MOSFETs, it becomes important to investigate the impact of a ferroelectric material in the gate stack, resulting in negative capacitance (NC) behavior, on the device performance. In this work, through calibrating the FDSOI MOSFET (as the baseline device architecture) with experimental data, we compare the impact of ferroelectric–dielectric (FE–DE) and ferroelectric–paraelectric–dielectric (FE–PE–DE) gate stacks on the electrostatics of an NCFET device for a practically realisable metal–ferroelectric–insulator–semiconductor (MFIS) structure. A suitable thickness of the ferroelectric (FE) layer in the FE–DE stack and the maximum drain–source voltage (

V

s

) that can be applied (determining the power supply voltage), are identified so as to ensure that constraints such as no negative differential resistance (NDR) effects, threshold voltage (

), sub-threshold slope (SS) invariability with drain voltage variations and hysteresis-free behavior in transfer characteristics (

From the thickness of the FE layer in the FE–DE stack, the thickness of the FE layer in the FE–PE–DE stack (PE layer thickness is fixed at 1 nm) is determined where with a thicker FE layer, we obtain similar capacitance from the FE–PE–DE gate stack to that obtained from the FE–DE stack, while meeting all the constraints applied to the FE–DE stack based NCFET, enabling determination of the power supply voltage. Through showing good SSs with reduced output conductance (

Vortex-based aggregation of micron particles in liquid using low-frequency vibration of a piezoelectric actuator
Authors: Huang Jun , Yang Jinlan , Liu Jiaming , Zhang Quan , Wang Yuan 
Published: August 2022

Abstract
In this letter, we proposed a control method for microparticles aggregation by utilizing liquid vortices. The piezoelectric cantilever beam, equipped with a probe, caused fluid flow through low-frequency vibration and formed vortexes at the end of the probe to gather microparticles. The particle image velocimetry tests and the flow field simulation results revealed that the forming region of the liquid vortexes was consistent with the microparticle aggregation region. The control method proposed here has the merits of simple structures, no damage to the controlled objects and large control ranges.
Electron–phonon coupling and superconductivity in an alkaline earth hydride CaH6 at high pressures

Published: August 2022

Abstract
Recently, an alkaline earth hydride CaH6 having a sodalitelike clathrate structure has been experimentally synthesized at megabar pressures with a maximum T
c of 215 K, comparable to that of a rare earth hydride LaH10. Here, based on first-principles calculations, we find that CaH6 exhibits a huge peak in the Eliashberg spectral function α
2
F around the low-frequency region of H-derived phonon modes, in contrast to LaH10 having a widely spreading spectrum of α
2
F over the whole frequencies of H-derived phonon modes. It is revealed that the huge peak of α
2
F in CaH6 is associated with an effective electron–phonon coupling (EPC) between low-frequency optical phonons and hybridized H 1s and Ca 3d states near the Fermi energy. As pressure increases, the strengthened H–H covalent bonding not only induces a hardening of optical phonon modes but also reduces the electron–phonon matrix elements related to the low-frequency optical modes, thereby leading to a lowering of the EPC constant. It is thus demonstrated that H-derived low-frequency phonon modes play an important role in the pressure-induced variation of T
c in CaH6. Furthermore, unlike the presence of two distinct superconducting gaps in LaH10, CaH6 is found to exhibit a single isotropic superconducting gap.
Rational, semi-rational solution and self-consistent sources extension of the variable-coefficient extended modified Kadomtsev-Petviashvili equation
Authors: Hai Rihan , Gegen Hasi 
Published: August 2022

Abstract
In this paper, we apply Hirota bilinear method and determinant technique to derive the Nth-order rational solution expressed compactly in terms of Matsuno determinants for the variable-coefficient extended modified Kadomtsev-Petviashvili (mKP) equation. As a special case, we obtain the M-lump solution expressed in terms of 2M × 2M determinants for the mKPI equation and investigate the dynamical behaviors of 1- and 2-lump solutions. Furthermore, we present the Wronskian and Grammian solution for the variable-coefficient extended mKP equation. Based on the Grammian solution, we construct the line soliton, the line breather and the semi-rational solution on constant and periodic backgrounds for the mKPI equation. Through the asymptotic analysis, we show that the semi-rational solutions describe the fission and fusion of lumps and line solitons. In addition, we construct the variable-coefficient extended mKP equation with self-consistent sources via the source generation procedure and derive its N-soliton solution in the compact form of Grammian and Wronskian.

AbstractIn this paper, the first principle investigations are performed to compute the electronic, optical, magnetic and thermoelectric (TE) features of Ba1−xMnxS (x = 6.25%, 12.5% and 25%) alloys by using density functional theory (DFT). The semiconductor behavior of pure BaS and half metallic ferromagnetic (HMF) nature of Ba1−xMnxS (x = 6.25%, 12.5% and 25%) is confirmed by investigating electronic band structure (EBS) with spin-resolved density of states (DOS). The MTotis mainly originated from Mn atom due to the presence of 3d-orbitals. In addition, the optical constants including refractive index, absorption and optical spectrum, reflectivity and dielectric function are analyzed in the span of 0–10 eV. It is found that the studied alloy operate within visible to ultraviolet (UV) energy range. Moreover, the TE properties such as figure of merit (ZT), power factor (PF), electrical and thermal conductivity are also calculated by using the BoltzTrap package. The high values of ZTof Ba1−xMnxS (x = 6.25%, 12.5% and 25%) qualify it for use in TE applications.The outcomes revealed the application of Ba1−xMnxS in spintronic and TE gadgets.

Abstract
In a ΛCDM universe, most galaxies evolve by mergers and accretions, leaving faint and/or diffuse structures, such as tidal streams and stellar halos. Although these structures are a good indicator of galaxies’ recent mass assembly history, they have the disadvantage of being difficult to observe due to their low surface brightness (LSB). To recover these LSB features by minimizing the photometric uncertainties introduced by the optical system, we developed a new optimized telescope named K-DRIFT pathfinder, adopting a linear astigmatism free-three mirror system. Thanks to the off-axis design, it is expected to avoid the loss and scattering of light on the optical path within the telescope. To assess the performance of this prototype telescope, we investigate the photometric depth and capability to identify LSB features. We find that the surface brightness limit reaches down to μ

r,1σ
∼ 28.5 mag arcsec−2 in 10″ × 10″ boxes, enabling us to identify a single stellar stream to the east of NGC 5907. We also examine the characteristics of the point-spread function (PSF) and find that the PSF wing reaches a very low level. Still, however, some internal reflections appear within a radius of ∼6′ from the center of sources. Despite a relatively small aperture (0.3 m) and short integration time (2 hr), this result demonstrates that our telescope is highly efficient in LSB detection.

Published: August 2022

Abstract
Very long baseline interferometry (VLBI) is an important deep-space tracking technology from radio astronomy. A mission that uses VLBI, China’s lunar sample-return mission Chang’E-5 (CE-5) collects soil samples on the lunar surface, arrives at a rendezvous point, and docks in the lunar orbit through cooperation of the Orbiter and the Ascender. During rendezvous and docking, the Chinese VLBI network (CVN) used same beam VLBI (SBI) to observe two high-velocity probes simultaneously. However, before the launching of the CE-5, CVN lacked the capability to examine dynamic dual-target tracking ability of SBI mode because there were no similar space probes can be used in tests of upgraded VLBI data-processing system. This study proposes a method to simulate VLBI signals and acquire relevant data from the dual-target probe and calibration quasar signals recorded by each station according to the orbits and beacons of probes, station coordinates, etc. The real-time data-processing capability of the system is verified by processing the simulated data during rendezvous and docking. The consistency between simulation and VLBI data-processing was consistent to better than 0.05 ns. This method is universal and can also be used in VLBI simulation and orbital analysis of other deep-space probes.

Abstract
The constant search for protection the soldier during training and participation in hostilities led us to aspire to develop types of energetic materials of a special nature that qualify them to reach the maximum levels of safety during handling, transportation and uses. In this work, we focus on one of these compounds, which is the main component of the preparation of low sensitive compositions. DNAN is an explosive with low sensitivity. Preparation of DNAN in laboratory scale was performed; explosive characterization was presented. Impact and friction sensitivities of DNAN, heat of combustion and detonation velocity were specified. TGA and DSC were used to investigate the DNAN thermal behavior under specific conditions. It was concluded that sensitivity of DNAN is lower than TNT and the chosen cyclic nitramines. The detonation properties of DNAN are slightly lower than TNT however DNAN is candidate individually or with other explosives to replace TNT in low sensitive compositions to full fill the safety and security manipulation of ammunitions.

Abstract
The study area constitutes the Eastern flank of the Nile Delta between longitudes, 31° 39’ 9.2″–32° 20’ 9.6″ E and latitudes 31° 37′13″-31° 0′ 54″N, in the shoreline between Port-Said and Damietta. The radioelement contents were measured by gamma-spectrometry using NaI-detector and were studied mineralogically using binuclear and Environmental Scanning Electron microscopes after separation of heavy minerals by heavy liquids. eU, eTh, RaeU and K contents in the studied sediments and sabkhas are ranged from (1-2 ppm), (3-17 ppm), (1-4 ppm) and (0.45-1.25 wt.%) with averages 1.34, 7.18, 1.89 ppm and 0.77 wt.%, respectively. The average of radioelement contents is lower than the international averages, while the average of eTh/eU ratio is higher. High eTh/eU ratio reflects the poor weathering, rapid deposition of these sediments and the dominance of detrital radioactive minerals such as xenotime, monazite and zircon. eU/RaeU ratio average (0.9), is lower than unity and indicate the disequilibrium in the studied coastal sediments, suggesting disequilibrium and uranium migration out. The heavy minerals are represented meanly by magnetite, ilmenite, zircon, rutile, garnet, monazite, pyroxene and amphibole.

Published: August 2022

Abstract
Developing superconducting cable for railway power transmission should lead to increased regeneration efficiency, reduced power loss, equalization of load between substations. In order to realize a kilometer-class superconducting feeder cable, on-site joint technique between superconducting feeder cables is required. For joining superconducting cables at railway construction sites, we conducted solder joining of superconducting tapes and its evaluation in the laboratory. We performed electromagnetic analysis of the joints by the finite element method in order to obtain a prospect of the optimum conditions of the solder joining. The target value of the joint resistance to 10−7 Ω class will be achieved by the solder joining regardless of the solder thickness and the joint length. Referring to the analysis results, mechanical and electrical properties measurement of the joined superconducting tape was conducted. From the results of the tensile and bending test, it is found that the solder joined superconducting tape with the lap length of more than 20 mm achieve the mechanical and electrical targets. These results are being utilized for cable joining at railway construction sites.

Published: August 2022

Abstract
One of the unique applications of single-flux-quantum (SFQ) circuitry is a digital-to-analog converter (DAC) of which the output voltage is defined by the Josephson effect. Recently, we have designed and operated rapid single-flux-quantum (RSFQ) DACs with frequency modulation of SFQ pulse sequences. In this paper, we report our design and test results of a 4-bit RSFQ-DAC based on the configuration of the “sum of selected bits sequence (Σ-SBS)”. By adjusting the timing margins, in addition to the fabrication using the Nb integration process with the critical current density as high as 10 kA/cm2, the maximum output voltage up to 260 μV was demonstrated.

Abstract
The European Space Agency’s Gaia spacecraft was launched in 2013 and has been in operation ever since. It has a focal plane of 106 Charge-Coupled Devices (CCDs) which are of the CCD91-72 variant, custom designed by Teledyne e2v. The detectors have been making measurements of parallaxes, positions, velocities, and other physical properties of over one billion stars and other astronomical objects in the Milky Way. Whilst operating in space, CCDs undergo non-ionizing displacement damage from incoming radiation. This causes radiation induced trap defects to form in the silicon lattice which can trap electrons during readout and increase the charge transfer inefficiency (CTI) of the devices significantly. From analysis of in-flight charge calibration data, Gaia’s CTI values have been measured to be lower than what was expected based on the on-ground pre-flight tests. In this study, the CTI and trap landscape in both in-flight and irradiated on-ground devices are modelled to fit the new datasets. This was done thanks to the help of a detector simulation toolkit called Pyxel which implemented a version of a CTI model developed for Gaia called the Charge Distortion Model (CDM). These results provide more insights into the nature of radiation damage and the resulting trap landscapes, both in space and from on-ground irradiations.
A biomimetic three-layered fibrin gel/PLLA nanofibers composite as a potential scaffold for articular cartilage tissue engineering application

Published: August 2022

Abstract
Developing an engineered scaffold inspired by structural features of healthy articular cartilage (AC) has attracted much attention. In this study, the design and fabrication of a three-layered fiber/hydrogel scaffold in which each layer replicates the organization of a pertinent layer of AC tissue is aimed. To this end, electrospun poly-L-lactic acid (PLLA) nanofibers are prepared and fragmented into nano/micro cylinders via aminolysis. Three-layers of the scaffold, a fibrin coated fibrous layer, a fibrin gel (FG) layer incorporating chopped fibers and a FG embedding cylindrical aligned fibrous mat perpendicular to articulating surface, respectively served as an upper, middle and bottom layers, are prepared. The layers’ physicomechanical characteristics are comprehensively evaluated. Results show that optimized electrospinning set up results in the smallest fibers diameter of 367 ± 317 nm and successful aminolysis provides amine-functionalized chopped nanofibers with a mean length of 1.46 ± 0.9 µm. Static mechanical analysis of the layers demonstrates that tensile Young’s modulus of the upper layer is 152 ± 17 MPa while compressive moduli of the middle and bottom layers are 9.8 ± 3.8 and 25.3 ± 5.2 KPa, respectively and the compressive modulus of three-layered scaffold is 13.7 ± 2.5 KPa. Assessing mechanical parameters under dynamic loading also shows that adding fibrous part in the composite scaffold layers enhances viscoelastic behavior of FG. Also, incorporation of 0.25% chopped fibers into the fibrin matrix notably enhances the equilibrium water content; however, it increases in-vitro weigh loss rate from 6% to 10.5% during a seven-day period. Cytocompatibility analysis confirms that all layers possess acceptable cytocompatibility. In a conclusion, the designed three-layered composite structure successfully mimics the physicomechanical as well as microstructural features of AC and could be suggested as a potential scaffold for this tissue regeneration.
Preparation of α-MoO3 from H3PMo12O40 precursor: synthesis of 1,2-cyclohexanediol from cyclohexene over α-MoO3-TiO2 catalyst
Authors: AlGarni Tahani Saad , Abduh Naaser A Y , Kahtani Abdullah Al , Aouissi Ahmed 
Published: August 2022

Abstract
A series of α-MoO3-TiO2 mixed oxides were prepared by calcining a mixture of the heteropolyacid H3PMo12O40 and TiO2 at temperatures ranging from 350 °C to 600 °C. The mixed oxides thus prepared were characterized and tested for the oxidation of cyclohexene by the oxidizing mixture H2O2/CO2. FTIR and XRD characterizations showed that the Keggin structure of H3PMo12O40 was preserved for calcination temperatures below 400 °C. Above 450 °C, Keggin’s structure collapses. XRD analysis revealed that as the calcination temperature increased, more orthorhombic α-MoO3 was formed. Analysis of the reaction mixture by GC-MS showed that oxidation by the H2O2/CO2 mixture leads to 1,2-cyclohexanediol as the main product and to 2-cyclohexene-1-one and 2-cyclohexene-1-ol as minor products. Oxidation by H2O2/CO2 mixture proved to be more effective than H2O2 alone and CO2 alone. The conversion (69.4%) and the 1,2-cyclohexanediol selectivity (93.2%) obtained over α-MoO3-TiO2 mixed oxides, higher than that obtained with TiO2 monoxide and α-MoO3 monoxide, suggest a synergistic effect between TiO2 and α-MoO3. This efficient and stable catalyst after reuse can be developed for the synthesis of diols.
