Perceived Supervisor Support for Health Affects Presenteeism
Authors: Mori Takahiro , Nagata Tomohisa , Nagata Masako , Odagami Kiminori , Mori Koji 
Published: September 2022

Objective
We investigated how perceived supervisor support for health (PSSH) affects the occurrence of presenteeism 1 year later.

Methods
A prospective cohort study was conducted using a questionnaire survey. In total, 10,718 nonmanagerial employees in seven companies in Japan were included in the analyses. We conducted multilevel logistic regression analyses nested by company to estimate the odds ratios (ORs) of the relationship between PSSH at baseline and high presenteeism at follow-up.

Results
The ORs for high presenteeism at follow-up were significantly higher for high (OR, 1.31; 95% confidence interval [CI], 1.14 to 1.51), low (OR, 1.63; 95% CI, 1.37 to 1.94), and very low PSSH (OR, 2.42; 95% CI, 1.88 to 3.12), compared with very high PSSH.

Conclusions
Lower PSSH can induce high presenteeism, suggesting that increasing PSSH is important to reduce the occurrence of presenteeism in companies.
Advanced imaging and theranostics in thyroid cancer
Authors: Roseland Molly E. , Dewaraja Yuni K. , Wong Ka Kit 
Published: September 2022

Purpose of review
Thyroid cancers are endocrine neoplasms with diverse gene expression and behavior, for which constantly evolving anatomic and functional imaging/theranostic agents have an essential role for diagnosis, staging, and treatment.

Recent findings
To achieve definitive diagnosis, neck ultrasound and associated risk stratification systems, notably Thyroid Imaging Reporting and Data System (TI-RADS), allow improved thyroid nodule characterization and management guidance. Radioactive iodine-131 (RAI) has long played a role in management of differentiated thyroid cancer (DTC), with recent literature emphasizing its effectiveness for intermediate-high risk cancers, exploring use of dosimetry for personalized medicine, and potential for retreatment with RAI following tumor redifferentiation. Iodine-124 positron emission tomography/computed tomography (PET/CT) has promising application for DTC staging and dosimetry. F18-fluorodeoxyglucose (FDG) PET/CT is used for staging of high risk DTC and identification of noniodine-avid disease recurrences, with metabolic uptake consistently portending poor prognosis. Poorly differentiated and anaplastic thyroid cancers are best assessed with anatomic imaging and F18-FDG PET/ CT, though recent studies show a potential theranostic role for Ga68/Lu177-prostate-specific membrane antigen. Medullary thyroid cancers are evaluated with ultrasound, CT, magnetic resonance imaging, and various positron-emitting radiotracers for PET imaging (F18-DOPA, F18-FDG, and recently Ga68-1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA)–octreotate (DOTATATE)); the latter may enable treatment with Lu177-DOTATATE.

Summary
Multidisciplinary collaboration is essential to streamline appropriate management, given the wide array of available imaging and new therapies for metabolic and genetically complex cancers.
Pilot Tone‐Triggered MRI for Quantitative Assessment of Cardiac Function, Motion, and Structure
Authors: Lin Kai , Sarnari Roberto , Speier Peter , Hayes Carmel , Davids Rachel , Carr James C. , Markl Michael 
Published: September 2022

Objective
The aim of this study was to test the hypothesis that there are good agreements between cardiac functional and structural indices derived from magnetic resonance imaging (MRI) sequences triggered with pilot tone (PT) and electrocardiogram (ECG).

Materials and Methods
Sixteen healthy volunteers (11 male, age 21–76 years) underwent a cardiac MRI scan. Cine MRI, T1, and T2 mapping were acquired by using PT and ECG triggering. Quantitative measurements, including left and right ventricular end-diastolic volume, end-systolic volume, stroke volume, ejection fraction, longitudinal strain, left ventricular T1 and T2 values, left and right atrial longitudinal strain, and maximal/minimal volumes, were measured. The interclass correlation coefficient, coefficient of variation, and Bland-Altman plots were used to evaluate the agreements between measurements derived by MRI sequences triggered with 2 methods.

Results
There were no significant differences among end-diastolic volume, end-systolic volume, stroke volume, ejection fraction, left ventricle mass, T1 and T2 values, or longitudinal strains acquired using PT and ECG. There were good agreements and low variations between the levels of these indices acquired with PT and ECG. Interclass correlation coefficients mainly ranged from 0.73 to 0.98. The coefficients of variation ranged from 1.4% to 22.6%.

Conclusions
Pilot tone‐triggered MRI provides comparable measurements of cardiac function, motion, and structure as ECG-triggered MRI. Pilot tone has the potential to become a backup of ECG gating in cardiovascular imaging.
System norm regularization methods for Koopman operator approximation
Authors: Dahdah Steven , Forbes James R. 
Published: September 2022

Approximating the Koopman operator from data is numerically challenging when many lifting functions are considered. Even low-dimensional systems can yield unstable or ill-conditioned results in a high-dimensional lifted space. In this paper, Extended Dynamic Mode Decomposition (DMD) and DMD with control, two methods for approximating the Koopman operator, are reformulated as convex optimization problems with linear matrix inequality constraints. Asymptotic stability constraints and system norm regularizers are then incorporated as methods to improve the numerical conditioning of the Koopman operator. Specifically, the

norm is used to penalize the input–output gain of the Koopman system. Weighting functions are then applied to penalize the system gain at specific frequencies. These constraints and regularizers introduce bilinear matrix inequality constraints to the regression problem, which are handled by solving a sequence of convex optimization problems. Experimental results using data from an aircraft fatigue structural test rig and a soft robot arm highlight the advantages of the proposed regression methods.
Costly incentives design from an institutional perspective: cooperation, sustainability and affluence
Authors: Zhou Xin , Belloum Adam , Lees Michael H. , van Engers Tom , de Laat Cees 
Published: September 2022

Incentives are usually introduced by the regulator entity (third-party), to promote cooperation in a market. The implementation of incentives is always costly and thus might fail to be enforced sustainably. This work aims at exploring the effects of incentives from an institutional perspective, while coping with the scenario where the third-party is part of the system but not composed by players. The evolutionary game theory (EGT) framework is applied to identify the incentives that lead to pure cooperation. In contrast to traditional EGT, this paper introduces an elimination mechanism that can reduce the market size. The incentives identified in the EGT analysis are further examined in simulation experiments which measure the market size, affluence and sustainability. The findings show: (1) light punishment leads to a reduction of the market size, yet heavier punishment is beneficial to the market size and wealth; (2) mixed incentives will generally lead to different wealth of the third party and of the participants. While under moderate strength, the wealth of both parties is the same and their overall wealth is maximal; (3) for sustainability, pure punishment (resp. reward) is sustainable (resp. unsustainable), the sustainability of mixed incentives depends on both their strength and agents’ rationality level.

AbstractCurrent organ-on-a-chip (OoC) systems mimic important aspects of specific organ and tissue functions, however, many commercial and academic devices are either too simple for advanced assays or require a complicated support set-up including external driving systems such as pumps and tubing that hamper scalability and robustness.We have developed a novel, pump-less directional flow recirculating organ-on-a-chip (rOoC) platform that creates continuous or pulsed directional gravity-driven flow by a combination of a 3D-tilting system and an optimized microfluidic layout.The rOoC platform allows growing and connecting tissue or organ representations on-chip with the possibility of incorporating barrier functions, gradients, and circulating cells. Using the rOoC platform we demonstrate simple and reproducible endothelialisation, hepatic organoid integration, and the first steps of vascularization of 3D organ representations on-chip.

ABSTRACTTHOC6 is the genetic basis of autosomal recessive THOC6 Intellectual Disability Syndrome (TIDS). THOC6 facilitates the formation of the Transcription Export complex (TREX) tetramer, composed of four THO monomers. The TREX tetramer supports mammalian mRNA processing that is distinct from yeast TREX dimer functions. Human and mouse TIDS model systems allow novel THOC6-dependent TREX tetramer functions to be investigated. Biallelic loss-of-function (LOF) THOC6 variants do not influence the expression and localization of TREX members in human cells, but our data suggests reduced binding affinity of ALYREF. Impairment of TREX nuclear export functions were not detected in cells with biallelic THOC6 LOF. Instead, mRNA mis-splicing was observed in human and mouse neural tissue, revealing novel insights into THOC6-mediated TREX coordination of mRNA processing. We demonstrate that THOC6 is required for regulation of key signaling pathways in human corticogenesis that dictate the transition from proliferative to neurogenic divisions that may inform TIDS neuropathology.

Published: September 2022

ABSTRACTPyramidal tract neurons (PTNs) are fundamental elements for motor control. However, it is largely unknown if PTNs are segregated into different subtypes with distinct roles in movement performance. Using anatomical, electrophysiological and optogenetics tools, we analyzed in both sexes’ mice motor cortex, PTNs projecting to red and pontine midbrain nuclei, which are important hubs connecting cerebral cortex and cerebellum playing a critical role in the regulation of movement. We reveal that vast majority of M1 neurons projecting to the red and pontine nuclei constitutes different populations. Corticopontine neurons have higher conduction velocities and morphologically, a most homogeneous dendritic and spine distributions along cortical layers. Optogenetically inhibiting either kind projection, differentially affects forelimb movement onset and execution in a lever press task, but only the activity of corticopontine neurons is significantly correlated with trial-by-trial variations in reaction time. The results indicate that cortical neurons projecting to the red and pontine nuclei constitute distinct functional and anatomical pathways and they contribute differently to sensorimotor integration, suggesting that layer 5 output neurons are functionally compartmentalized generating, in parallel, different downstream coding.
Y-type quadrotor radar cross-section analysis
Authors: Zhou Zeyang , Huang Jun 
Published: September 2022

PurposeThe purpose of his paper is to study the radar stealth performance of a Y-type quadrotor with coaxial rotors and parallel rotors.Design/methodology/approachThis Y-type quadrotor is designed as an aerodynamic layout with parallel twin rotors at the front and coaxial twin rotors at the rear. The multi-rotor scattering (MRS) method based on multi-rotor dynamic simulation (MRDS) and electromagnetic scattering module (ESM) is presented. MRDS is used to simulate the complex rotation of parallel rotors and coaxial rotors. ESM is used to calculate the instantaneous radar cross-section (RCS) of the quadrotor.FindingsFor a single rotor, the minimum period of the RCS curve at a given azimuth is equal to the basic passage time of the blade, where increasing the speed can shorten this minimum period. When the elevation angle increases, the forward RCS fluctuation of the quadrotor increases, while the average RCS decreases. The change of the roll angle will affect both the mean and the maximum difference of the RCS–time curve at the given lateral azimuth. The increase of the pitch angle will enhance the dynamic amplitude of the RCS–time curve under the forward azimuth.Practical implicationsThe research in this article can provide reference for the stealth design of the Y-type quadcopter in the future.Originality/valueThe originality is the establishment of the MRS method. This method could provide value for dealing with the electromagnetic scattering problem of coaxial rotors and parallel rotors.
Localized magnetic properties measurement of interlocking core laminations
Authors: Li Yongjian , Zhang Kai , Dou Yu , Lin Zhiwei , Fu Yu , Zhang Changgeng 
Published: September 2022

Purpose
In rotational alternating current machines, interlocking is a commonly used manufacturing method to fix laminated silicon steel cores. The purpose of this study is to measure the localized magnetic properties more comprehensively and to analyze the deteriorated magnetic properties caused by interlocking more accurately.

Design/methodology/approach
A movable B–H sensor is designed in this paper. The localized magnetic properties measurement was performed to investigate the magnetic properties around the interlocks with various sizes, various orientations and various numbers of laminations. Then, the damaged area caused by the interlocking was quantified, and the magnetic degradation of different degrees is layered.

Findings
The measurement results have shown that the interlocks with larger sizes, along the transverse direction and on 10-layer laminate, will lead to more serious magnetic degradation, and the maximum loss increment can reach up to 70%.

Originality/value
This work is an improvement and optimization based on the previous overall magnetic measurement of the interlock. The quantitative results of the localized magnetic measurement will have a certain significance for the accurate modeling and simulation of the electrical machines and provide valuable guidance for the optimization of the actual production process of the motor.
Strategic deviance and trade credit
Authors: Damle Harshali , Sinha Rajesh Kumar 
Published: September 2022

PurposeLiterature sparsely documents the association between the deviant behavior of a firm and its financial policies. Trade credit is one of the most critical financial policies of a firm. In this study, the authors examine the association between strategic deviance and trade credit.Design/methodology/approachThe authors explore a strategy-based explanation for trade credit by examining whether strategic deviance affects trade credit using a sample of 33 countries from 1996 to 2020. The authors test the hypothesis using static OLS regression models. To address autocorrelation and endogeneity issues, the authors use dynamic OLS models, lag models, and instrumental variable approach.FindingsThe authors find that an increase in strategic deviance reduces both demand and supply of trade credit, and the study’s results indicate that a one standard deviation increase in strategic deviance leads to a 1.34% decrease in the demand for trade credit. Also, a one standard deviation increase in strategic deviance leads to a 2.26% fall in the supply of trade credit.Practical implicationsThis study facilitates managers to formulate trade credit policies when choosing a deviant strategy.Originality/valueTo the best of the authors’ knowledge, this is the first study to explore the association between strategic deviance and trade credit policies.
International evidence on the relationship between corporate ethics and dividend policy
Authors: Farooq Omar , Ahmed Neveen 
Published: September 2022

PurposeThis paper aims is to document the relationship between corporate ethics prevailing in the country and the dividend policies adopted by firms.Design/methodology/approachThe paper uses the data of non-financial firms from 61 countries to test the arguments presented in this paper. The data cover the period between 2010 and 2017.FindingsThis paper shows that dividend policies adopted by firms are sensitive to corporate ethics prevailing in the country. The firms headquartered in countries with relatively strong corporate ethics are less likely to pay dividends than firms headquartered in countries with relatively weak corporate ethics. These findings are robust across various proxies of dividend policy and across various estimation procedures. The paper, however, also shows that the relationship between corporate ethics and dividend policies is confined only to countries with strong institutional environment. This relationship breaks down in countries with weak institutional environment. Lastly, the paper shows that the value of dividend policy is more pronounced in countries with relatively weak corporate ethics.Originality/valueUnlike the attempts to relate firm-level ethics and dividend policy, this paper focuses on the relationship between country-level indicator of corporate ethics and dividend policies. The benefit of using the country-level indicator of corporate ethics is that it highlights the general attitude of corporations with respect to ethics.
Research on wear performance of new type CL60 steel for metro wheel
Authors: Yidong Xie , Peiweni Sun , Qiang Li , Caozheng Fu , Zhu AiHua , Yang Jianwei , Ma Chaochao 
Published: September 2022

Purpose
The CL60 steel wheels of metro vehicles running on a specific line need frequent reprofiling due to rapid wear. Considering this problem, a new material for metro wheels was designed. The friction and wear properties of the new material were studied, to reduce the wear rate and extend the service life of metro wheels.

Design/methodology/approach
Wheel specimens made of the two steel materials were tested using a GPM-60 wear tester under laboratory conditions. A field test was conducted on a specific metro line to track the wear in wheels made of the new material and CL60 steel wheels.

Findings
Under the laboratory conditions, the wear loss in the new material was 24.44% lower than that in CL60 steel. The field test revealed that compared to CL60 steel wheels, the new CL60 steel wheels showed a 19.42% decrease in tread wear on average. The field measurements for the wheels made of the new material are consistent with the results of laboratory simulation, suggesting relatively high wear resistance of the new material.

Practical implications
The results of the study can provide guidance on how to properly select steel material for metro wheels to avoid rapid wear and frequent reprofiling and reduce operating costs.

Originality/value
A new material for metro wheels was designed and developed by optimizing the content of Cr, Si, Mn, V and other elements. This material proved to have better wear resistance in both laboratory and field testing.

Price and cooperation decisions in a cooperative R&D supply chain with different licensing models
Authors: Yan Fei , Chen Hong-Zhuan , Zhang Zhichao 
Published: September 2022

PurposeIndustry practice has shown that technology licensing has an important effect on the R&D cooperation between firms. Different licensing methods will significantly impact a supply chain member's cooperative and price R&D decisions. However, there is scant literature investigating the decision on technology licensing and its impact on a supply chain member's price and cooperative R&D decisions. To address this gap, the authors investigate the R&D cooperation and the technology licensing in a supply chain formed of an original equipment manufacturer (OEM), a contract manufacturer (CM), and a third-party manufacturer which will compete with the OEM when the technology licensing occurs.Design/methodology/approachThe authors investigate two licensing patterns, royalty licensing, fixed fee licensing together with the no licensing, within the R&D cooperative supply chain by developing two three-stage and a two-stage Stackelberg models.FindingsCompare to the no licensing strategy, technology licensing always benefits to the OEM and the society especially when the technology efficiency and the brand power of the third-party manufacturer are more significant; the royalty licensing benefits to the OEM more when the technology efficiency and the brand power of the third-party manufacturer are higher; the fixed fee licensing benefits to the OEM more when the technology efficiency and the brand power of the third-party manufacturer are lower.Practical implicationsThe royalty licensing is more effective for mitigating price competition intensity and helping firms to maintain higher sales margins; the fixed fee licensing induces firms' lower sales margins but increases the firms' sales quantities; in most cases, the fixed fee licensing is optimal from the perspectives of consumer and society, however, the CM's investment intention to the R&D technology with the fixed fee licensing is lower.Originality/valueSo far, different licensing models under the R&D cooperation have not been investigated, and the authors propose two three-stage Stackelberg models with considering the competition caused by technology licensing under the R&D cooperation to deal with the cooperative R&D and technology licensing issues.
