AbstractAimThis study aimed to explore the effect of training on organizational commitment, the mediating effect of employability and the moderating role of person–organization fit.DesignA correctional cross‐sectional research design was adopted for this study.MethodsA questionnaire‐based survey of 859 nurses in a public hospital in Western China was conducted to identify their perceptions of training, employability, organizational commitment and person–organization fit. Hierarchical linear regression and conditional process analysis on moderated mediation were performed.ResultsTraining had a positive effect on organizational commitment (p < .01). Internal and external employability mediated the relationship between training and organizational commitment (p < .01). Person–organization fit enhanced the indirect effect of training on organizational commitment through external employability (p < .05).

Published: August 2022

AbstractBackgroundFocussed Ultrasound (FUS) combined with microbubbles (MBs) was proven a promising modality for non‐invasive blood brain barrier disruption (BBBD). Herein, two devices for FUS‐mediated BBBD in rodents are presented.MethodsA two‐axes robotic device was manufactured for navigating a single element FUS transducer of 1 MHz relative to the brain of rodents. A second more compact device featuring a single motorized vertical axis was also developed. Their performance was assessed in terms of motion accuracy, MRI compatibility and trans‐skull BBBD in wild type mice using MBs in synergy with pulsed FUS.ResultsSuccessful BBBD was evidenced by the Evans Blue dye method, as well as by Fibronectin and Fibrinogen immunostaining. BBB permeability was enhanced when the applied acoustic intensity was increased.ConclusionsThe proposed devices constitute a cost‐effective and ergonomic solution for FUS‐mediated BBBD in small animal models. Further experimentation is needed to examine the repeatability of results and optimise the therapeutic protocol.
High‐performance quadrotor slung load transportation with damped oscillations
Authors: Reis Joel , Yu Gan , Cabecinhas David , Silvestre Carlos 
Published: August 2022

AbstractThis paper presents a control solution for the problem of slung load transportation, with simultaneous damping of oscillations, using an underactuated autonomous quadrotor vehicle in the presence of external disturbances. The strategy put forward is divided into two parts: (i) resorting to an error definition that encompasses the pendular motion of the suspended load, a controller inspired in sliding‐mode theory is developed to compute a vectored thrust actuation that actively damps out the system's oscillations; (ii) two different approaches are illustrated for the stage of attitude tracking: one stemming from the conventional backstepping technique, which controls the vehicle in angular velocity commands; and another, also based on sliding‐mode theory, and built intrinsically in , that produces torque commands. The overall control scheme is proved to be robust and stable, with the load oscillations shown to be damped out in the process. Simulation and experimental results are presented in a trajectory tracking scenario to validate and assess the robustness and efficiency of the proposed technique.

AbstractCadmium (Cd) is detrimental to animals, but nephrotoxic effects of Cd on duck have not been fully elucidated. To evaluate the impacts of Cd on Ca homeostasis and autophagy via PLC‐IP3‐IP3R pathway, primary duck renal tubular epithelial cells were exposed to 2.5 μM and 5.0 μM Cd, and combination of 5.0 μM Cd and 10.0 μM 2‐APB or 0.125 μM U‐73122 for 12 h (U‐73122 pretreated for 1 h). These results evidenced that Cd induced [Ca2+]c overload mainly came from intracellular Ca store. Cd caused [Ca2+]mit and [Ca2+]c overload with [Ca2+]ER decrease, elevated Ca homeostasis related factors (GRP78, GRP94, CRT, CaN, CaMKII, and CaMKKβ) expression, PLC and IP3 activities and IP3R expression, but subcellular Ca2+ redistribution was reversed by 2‐APB. PLC inhibitor U‐73122 dramatically relieved the changes of the above indicators induced by Cd. Additionally, U‐73122 obviously reduced the number of autophagosomes and LC3 accumulation spots, Atg5, LC3A, LC3B mRNA levels and LC3II/LC3I, Beclin‐1 protein levels induced by Cd, and markedly elevated p62 mRNA and protein levels. Overall, the results verified that Cd induced [Ca2+]c overload mainly originated from ER Ca2+ release mediated by PLC‐IP3‐IP3R pathway, then triggered autophagy in duck renal tubular epithelial cells.
Zinc supplementation improves antioxidant status, and organic zinc is more efficient than inorganic zinc in improving the bone strength of aged laying hens

AbstractBackgroundThere have been some reports indicating that supplementation of zinc could alleviate the negative effects of age on egg quality in laying hens. However, information regarding these positive effects on health and zinc deposition in the body is limited.ObjectivesThe aim of the present study was to investigate the effect of organic and inorganic sources of zinc on the antioxidant activity, bone strength, and zinc deposition in the tissues of older laying hens.MethodsIn a completely randomized design, 175 Leghorn laying hens (w36) aged 80 weeks were allocated into seven treatment groups and five replications: control (without zinc supplementation), zinc sulphate treatments (15, 30, and 45 mg/kg), and organic zinc treatments (15, 30, and 45 mg/kg).ResultsThere was a significant increase in feed intake in the zinc sulphate and organic zinc treatments compared to the control treatment (p < 0.05). The egg mass in organic and sulphate zinc showed a significant increase. The feed conversion ratio was decreased significantly in the organic zinc treatments (p < 0.05). Both organic and sulphate zinc supplements enhanced serum superoxide dismutase activity as an antioxidant index (p < 0.05). The cortical thickness of the tibia was improved in laying hens receiving 30 mg/kg organic zinc. Supplementation of zinc could lead to an increase in zinc deposition in tissues, and organic zinc boosts bone strength.ConclusionZinc supplementation can improve antioxidant activity, feed intake, and feed conversion ratio and enhance egg mass and optimal absorption of zinc in tissues. The use of 30 mg/kg organic zinc is recommended for improving the cortical thickness of the tibia in aged laying hens.
Synthesis and crystal structures of rhodium acetate paddle‐wheel complexes with anchor group‐functionalised and hydrogen bond‐supported axial ligands
Authors: Mang André , Linseis Michael , Winter Rainer F. 
Published: August 2022

AbstractWe report the synthesis and X‐ray structures of four Rh2(OAc)4(LAx)2 (OAc=acetate, CH3COO−) paddle‐wheel complexes (C1−C4) with methylthio‐modified axial ligands LAx derived from benzamidine (L1), anilinopyrimidine (L2) or isothiourea (L3, L4) that are capable of forming N−H⋅⋅⋅O hydrogen bonds to the equatorially bridging acetate ligands. This was done with the aim to suppress dissociation of the axial ligands and to make the complexes amenable to single‐molecule conductance measurements in a scanning tunneling microscope break‐junction (STM‐BJ) setup. The characteristic spectroscopic features (NMR, IR, vis), crystal structures, the hydrogen‐bonding motifs and a DFT‐based screening of their frontier molecular orbitals are presented. Our calculations suggest that hydrogen‐bonding stabilises axial ligand binding by 15 kJ/mol to 30 kJ/mol and that the HOMO of the rhodium paddle‐wheels is closer to the Au work function than the LUMO, so that the rhodium paddle‐wheels are expected to constitute hole conductors.
Large charges on the Wilson loop in $$ \mathcal{N} $$ = 4 SYM. Part II. Quantum fluctuations, OPE, and spectral curve
Authors: Giombi Simone , Komatsu Shota , Offertaler Bendeguz

Abstract
We continue our study of large charge limits of the defect CFT defined by the half-BPS Wilson loop in planar $$ \mathcal{N} $$
N
= 4 supersymmetric Yang-Mills theory. In this paper, we compute 1/J corrections to the correlation function of two heavy insertions of charge J and two light insertions, in the double scaling limit where the charge J and the ’t Hooft coupling λ are sent to infinity with the ratio J/$$ \sqrt{\lambda } $$

λ

fixed. Holographically, they correspond to quantum fluctuations around a classical string solution with large angular momentum, and can be computed by evaluating Green’s functions on the worldsheet. We derive a representation of the Green’s functions in terms of a sum over residues in the complexified Fourier space, and show that it gives rise to the conformal block expansion in the heavy-light channel. This allows us to extract the scaling dimensions and structure constants for an infinite tower of non-protected dCFT operators. We also find a close connection between our results and the semi-classical integrability of the string sigma model. The series of poles of the Green’s functions in Fourier space corresponds to points on the spectral curve where the so-called quasi-momentum satisfies a quantization condition, and both the scaling dimensions and the structure constants in the heavy-light channel take simple forms when written in terms of the spectral curve. These observations suggest extensions of the results by Gromov, Schafer-Nameki and Vieira on the semiclassical energy of closed strings, and in particular hint at the possibility of determining the structure constants directly from the spectral curve.
Lepton flavor violation, lepton (g − 2)μ, e and electron EDM in the modular symmetry
Authors: Kobayashi Tatsuo , Otsuka Hajime , Tanimoto Morimitsu , Yamamoto Kei 
Published: August 2022

Abstract
We study the lepton flavor violation (LFV), the leptonic magnetic moments (g − 2)μ, e and the electric dipole moment (EDM) of the electron in the Standard-Model Effective Field Theory with the ΓN modular flavor symmetry. We employ the stringy Ansatz on coupling structure that 4-point couplings of matter fields are written by a product of 3-point couplings of matter fields. We take the level 3 finite modular group, Γ3 for the flavor symmetry, and discuss the dipole operators at nearby fixed point τ = i, where observed lepton masses and mixing angles are well reproduced. Suppose the anomaly of the anomalous magnetic moment of the muon to be evidence of the new physics (NP), we have related it with (g − 2)e, LFV decays, and the electron EDM. It is found that the NP contribution to (g − 2)e is proportional to the lepton masses squared likewise the naive scaling. We also discuss the correlations among the LFV processes μ → eγ, τ → μγ and τ → eγ, which are testable in the future. The electron EDM requires the tiny imaginary part of the relevant Wilson coefficient in the basis of real positive charged lepton masses, which is related to the μ → eγ transition in our framework.
Anatomy of scalar mediated proton decays in SO(10) models

Abstract

Explicitly computing their couplings with the standard model fermions, we derive the effective operators including the possibility of mixing between the scalars stemming from a given representation. We find that such interactions at d = 6 are mediated by only three sets of scalars: T(3, 1, −1/3), $$ \mathcal{T} $$

Three additional colour triplets and their conjugates can mediate nucleon decay via d = 7 operators which violate also the B − L. We give general expressions for partial widths of proton in terms of the fundamental Yukawa couplings and use these results to explicitly compute the proton lifetime and branching ratios for the minimal non-supersymmetric SO(10) model based on 10 and $$ \overline{\mathbf{126}} $$

Quantization of the zigzag model
Authors: Donahue John C. , Dubovsky Sergei 
Published: August 2022

Abstract
The zigzag model is a relativistic integrable N-body system describing the leading high-energy semiclassical dynamics on the worldsheet of long confining strings in massive adjoint two-dimensional QCD. We discuss quantization of this model. We demonstrate that to achieve a consistent quantization of the model it is necessary to account for the non-trivial geometry of phase space. The resulting Poincaré invariant integrable quantum theory is a close cousin of $$ T\overline{T} $$

Going beyond ER=EPR in the SYK model
Authors: Berkooz Micha , Brukner Nadav , Ross Simon F. , Watanabe Masataka 
Published: August 2022

Abstract
We discuss generalizations of the TFD to a density matrix on the doubled Hilbert space. We suggest that a semiclassical wormhole corresponds to a certain class of such density matrices, and specify how they are constructed. Different semi-classical profiles correspond to different non-overlapping density matrices. We show that this language allows for a finer criteria for when the wormhole is semiclassical, which goes beyond entanglement. Our main tool is the SYK model. We focus on the simplest class of such density matrices, in a scaling limit where the ER bridge is captured by chords going from one space to another, encoding correlations in the microscopic Hamiltonian. The length of the wormhole simply encodes the extent these correlations are eroded when flowing from one side to the other.
One-dimensional sectors from the squashed three-sphere
Authors: Bomans Pieter , Pufu Silviu S. 
Published: August 2022

Abstract
Three-dimensional $$ \mathcal{N} $$
N
= 4 superconformal field theories contain 1d topological sectors consisting of twisted linear combinations of half-BPS local operators that can be inserted anywhere along a line. After a conformal mapping to a round three-sphere, the 1d sectors are now defined on a great circle of S3. We show that the 1d topological sectors are preserved under the squashing of the sphere. For gauge theories with matter hypermultiplets, we use supersymmetric localization to derive an explicit description of the topological sector associated with the Higgs branch. Furthermore, we find that the dependence of the 1d correlation functions on the squashing parameter b can be removed after appropriate rescalings. One can introduce real mass and Fayet-Iliopolous parameters that, after appropriate rescalings, modify the 1d theory on the squashed sphere precisely as they do on the round sphere. In addition, we also show that when a generic 3d $$ \mathcal{N} $$
N
= 4 theory is deformed by real mass parameters, this deformation translates into a universal deformation of the corresponding 1d theory.
CFD of roughness effects on laminar heat transfer applied to additive manufactured minichannels
Authors: Kadivar Mohammadreza , Tormey David , McGranaghan Gerard 
Published: August 2022

AbstractAdditive manufacturing has received significant interest in the fabrication of functional channels for heat transfer; however, the inherent rough surface finish of the additively manufactured channels can influence thermal performance. This study investigates the impact of roughness on the thermo-fluid characteristics of laminar forced convection in rough minichannels. A numerical model was developed to create 3D Gaussian roughness with specified root-mean-square height. The finite volume method was used to solve the conjugate heat transfer of developed laminar flow in square minichannels. For Reynolds numbers ranging from 200 to 1600, the simulation results indicated enhanced heat transfer and increased flow resistance as Reynolds number increases, compared to a smooth minichannel, where effects on heat transfer and flow friction were negligible. For channels with relative roughness (root-mean-square height to channel hydraulic diameter) of 0.0068, 0.0113, and 0.0167, increasing the Reynolds number led to increased friction factor by 1.56, 1.71, and 2.91%, while the Nusselt number was enhanced up to 0.03%, 32.74%, and 46.05%, respectively. Heat transfer reduced in roughness valleys due to the presence of local low-velocity fluid in these regions; however, recirculation regions can occur in deep valleys of high roughness, increasing heat transfer and flow friction. Heat transfer was enhanced over roughness peaks due to flow impingement on the windward face of roughness as well as intensified energy transfer to the channel wall from roughness. Moreover, surfaces with higher roughness have a greater number of high peaks providing a thermal-flow path of a larger area and a thermal conductivity greater than that of the fluid.

Abstract
Objective
To investigate the performance of quantitative CT analysis in predicting the prognosis of patients with locally advanced oesophageal squamous cell carcinoma (ESCC) after two cycles of induction chemotherapy before definitive chemoradiotherapy/radiotherapy.

Methods
A total of 110 patients with locally advanced ESCC were retrospectively analysed. Baseline chest CT and CT after two cycles of induction chemotherapy were analysed. A multivariate Cox proportional-hazard regression model was used to identify independent prognostic markers for survival analysis. Then, a CT scoring system was established. Time-dependent receiver operating characteristic (ROC) curve analysis and the Kaplan-Meier method were employed for analysing the prognostic value of the CT scoring system.

Results
Body mass index, treatment strategy, change ratios of thickness (ΔTHmax), CT value of the primary tumour (ΔCTVaxial) and the short diameter (ΔSD-LN), and the presence of an enlarged small lymph node (ESLN) after two cycles of chemotherapy were noted as independent factors for predicting overall survival (OS). The specificity of the presence of ESLN for death after 12 months was up to 100%. Areas under the curve value of the CT scoring system for predicting OS and progression-free survival (PFS) were higher than that of the RECIST (p < 0.05). Responders had significantly longer OS and PFS than non-responders.

Conclusion
Quantitative CT analysis after two cycles of induction chemotherapy could predict the outcome of locally advanced ESCC patients treated with definitive chemoradiotherapy/radiotherapy. The CT scoring system could contribute to the development of an appropriate strategy for patients with locally advanced ESCC.

Key Points
• Quantitative CT evaluation after two cycles of induction chemotherapy can predict the long-term outcome of locally advanced oesophageal cancer treated with definitive chemoradiotherapy/radiotherapy.
• A CT scoring system provides valuable imaging support for indicating the prognosis at the early stage of therapy.
• Quantitative CT evaluation can assist clinicians in personalising treatment plans.
Effects of carbon nanotubes addition on the superconducting properties and critical current density of NdBa2Cu3O7−δ
Authors: Chong Tet Vui , Loh Shin King , Liow Chiew Han , Abd-Shukor Roslan 
Published: August 2022

AbstractPolycrystalline NdBa2Cu3O7−δ samples with 0 to 1.5 wt% carbon nanotubes (CNTs) addition have been synthesized via the solid-state reaction method. The samples were examined by the four-point probe temperature-dependent electrical resistance, critical current density and AC susceptibility measurements. X-ray diffraction (XRD) patterns showed that the addition of CNTs did not change the orthorhombic structure of the samples and there was no systematic variation in the lattice parameters. CNTs addition increased the transition temperature with the highest onset transition temperature, Tc onset = 96 K for the 1 wt% added sample. The critical current density increased from 2600 mA/cm2 for the pure NdBa2Cu3O7−δ to 4960 mA/cm2 for the 1.0 wt% CNTs added sample. It is suggested that the grain boundaries improved with CNTs addition, and this plays an important role in the electrical transport properties. Addition of CNTs enhanced the flux pinning and improved the grain boundaries of high-temperature superconductors. The effect of CNTs on other cuprate high-temperature superconductors has also been compared with these NdBa2Cu3O7−δ samples.
