Complex Arterial Pathology of Angiomyolipomas of Tuberous Sclerosis
Authors: Yeisley Christopher D. , Tafreshi Shima , Moirano Joseph , Gandras Eric , Siegel David 
Published: April 2022

AbstractBased on observations at angiography, it was hypothesized that angiomyolipomas (AMLs) associated with tuberous sclerosis complex (TSC) have a more robust parasitic blood supply and require more complex embolization involving lower order vessels compared with the non-TSC patients' AMLs. This was a retrospective review of 71 patients who underwent angiography and embolization for renal AML at multiple centers within a single health system. All of the patients with TSC (11/11) were found to have “complex” tumor vascular supply. Of the patients with sporadic AML, 51/60 (85%) had “simple” tumor vascular supply. Sporadic cases with a complex tumor blood supply were larger tumors, with an average size of 11.5 cm. This study supports our hypothesis that AMLs associated with TSC have more complex tumor vascularity compared with sporadic lesions, and aims to better prepare interventionalists to deal with the complex cases.

Published: April 2022

Abstract
Background Inpatient portals are recognized to provide benefits for both patients and providers, yet the process of provisioning tablets to patients by staff has been difficult for many hospitals.
Objective Our study aimed to identify and describe practices important for provisioning an inpatient portal from the perspectives of nursing staff and provide insight to enable hospitals to address challenges related to provisioning workflow for the inpatient portal accessible on a tablet.
Methods Qualitative interviews were conducted with 210 nursing staff members across 26 inpatient units in six hospitals within The Ohio State University Wexner Medical Center (OSUWMC) following the introduction of tablets providing access to an inpatient portal, MyChart Bedside (MCB). Interviews asked questions focused on nursing staffs' experiences relative to MCB tablet provisioning. Verbatim interview transcripts were coded using thematic analysis to identify factors associated with tablet provisioning. Unit provisioning performance was established using data stored in the OSUWMC electronic health record about provisioning status. Provisioning rates were divided into tertiles to create three levels of provisioning performance: (1) higher; (2) average; and (3) lower.
Results Three themes emerged as critical strategies contributing to MCB tablet provisioning success on higher-performing units: (1) establishing a feasible process for MCB provisioning; (2) having persistent unit-level MCB tablet champions; and (3) having unit managers actively promote MCB tablets. These strategies were described differently by staff from the higher-performing units when compared with characterizations of the provisioning process by staff from lower-performing units.
Conclusion As inpatient portals are recognized as a powerful tool that can increase patients' access to information and enhance their care experience, implementing the strategies we identified may help hospitals' efforts to improve provisioning and increase their patients' engagement in their health care.

Development and Standardization of SCAN-C Test for Auditory Processing Disorders in Children
Authors: Keith Robert W. 
Published: April 2022

AbstractThis paper reports on the development and standardization of SCAN-C: Test for Auditory Processing Disorders in Children-Revised. The revisions include new test instructions that have been reworded to make them easier for young children, aural stimuli presented on a compact disc, a revision of the Competing Words subtest, and the addition of a Competing Sentences subtest. Normative data on the new test were obtained on 650 children age 5 years, 0 months, to 11 years, 11 months. Analysis of new standardization data revealed systematic improvement in performance with increasing age. A new method of calculating the composite standard score gives equal weighting to each subtest of SCAN-C. Subtest test-retest reliability was substantially improved over the original SCAN, with SCAN-C correlations ranging from .65 to .82 for 5 to 7 year olds. Concurrent validity tests found that SCAN-C test results can be viewed with the same confidence as SCAN.

A Case of Susac Syndrome
Authors: Yellin M. Wende , Johnson Thomas W. 
Published: April 2022

AbstractSusac syndrome is a readily recognized but often misdiagnosed disorder almost exclusively affecting women in the 20- to 40–year age range. Characterized by the clinical triad of encephalopathy, branch retinal artery occlusions, and sensorineural hearing loss, patients with Susac syndrome are often misdiagnosed with multiple sclerosis (MS). Unlike MS, however, the disease process extends over a 1- to 2–year period and then goes into remission. This presentation describes the progression of symptoms of a patient eventually diagnosed with Susac syndrome.

A button switch inspired duplex hydrogel sensor based on both triboelectric and piezoresistive effects for detecting dynamic and static pressure

Published: April 2022

The capability to sense complex pressure variations comprehensively is vital for wearable electronics and flexible human–machine interfaces. In this paper, inspired by button switches, a duplex tactile sensor based on the combination of triboelectric and piezoresistive effects is designed and fabricated. Because of its excellent mechanical strength and electrical stability, a double-networked ionic hydrogel is used as both the conductive electrode and elastic current regulator. In addition, micro-pyramidal patterned polydimethylsiloxane (PDMS) acts as both the friction layer and the encapsulation elastomer, thereby boosting the triboelectric output performance significantly. The duplex hydrogel sensor demonstrates comprehensive sensing ability in detecting the whole stimulation process including the dynamic and static pressures. The dynamic stress intensity (10–300 Pa), the action time, and the static variations (increase and decrease) of the pressure can be identified precisely from the dual-channel signals. Combined with a signal processing module, an intelligent visible door lamp is achieved for monitoring the entire “contact–hold–release–separation” state of the external stimulation, which shows great application potential for future smart robot e-skin and flexible electronics.

Published: April 2022

Abstract
Safety analyses for nuclear power plants were carried out in the past using a conservative approach. With the increase of the phenomenological knowledge, through experimental data, and computational power, it became possible to adopt best estimate thermal- hydraulic system codes to perform deterministic safety analyses. However, some uncertainties are still present in the models, correlations, initial and boundary conditions, etc. Therefore, it is fundamental to quantify the uncertainty of calculation. This approach is called “Best Estimate Plus Uncertainty” (BEPU). Among the available uncertainty analysis methodologies, the probabilistic method to propagate input uncertainty is widely adopted. In the present study, an uncertainty analysis of a cold leg large break loss of coolant accident in a generic PWR-900 MWe has been developed and it has been carried out coupling the best estimate thermal- hydraulic system code TRACE and the uncertainty quantification tool DAKOTA in the SNAP environment/architecture.
Characterization of Cs-free negative ion production in the ion source SPIDER by cavity ring-down spectroscopy

Published: April 2022

AbstractThe neutral beam injectors of the ITER experiment will be based on negative ion sources for the generation of beams composed by 1 MeV H/D particles. The prototype of these sources is currently under testing in the SPIDER experiment, part of the Neutral Beam Test Facility of Consorzio RFX, Padua, Italy. Among the targets of the experimentation in SPIDER, it is of foremost importance to maximize the beam current density produced by the accelerator. The SPIDER operating conditions can be optimized thanks to a cavity ring-down spectroscopy diagnostic, which provides line-integrated measurements of negative ion density in proximity of the accelerator apertures. The specific implementation in SPIDER shows a drift in ring down time measurements, which develops in a time scale of few hours, thus possibly affecting the negative ion density estimates in plasma pulses of 1 h duration, as required by ITER. Possible causes and solutions are discussed. Regarding the source performance, this paper presents how negative ion density is influenced by the RF power used to sustain the plasma, and by the magnetic filter field present in SPIDER to limit the amount of co-extracted electrons. In this study, SPIDER was operated in hydrogen and deuterium, in Cs-free conditions.
Unconventional optical properties of 2D Janus SMoSe induced by structural asymmetry
Authors: Zhang Jing , Wen Xiewen , Zhai Tianshu , Wiederrecht Gary P , Lou Jun 
Published: April 2022

Abstract
The Janus SMoSe monolayer that is best-known for its structural asymmetry is found to exhibit unconventional optical properties compared with its counterpart MoSe2. Optical transmittance measurements on monolayers that are directly synthesized on sapphire substrates reveal that the transmittance, as well as the real and imaginary parts of the optical dielectric constants of Janus SMoSe obtained from the Kramers–Kronig constrained analysis, show strong dependence on the polarization direction of the incident light. Meanwhile, the transmittance of the unpolarized light of Janus SMoSe becomes insensitive to light at incident angles up to 30°. The intrinsic dipoles induced by the structural asymmetry of Janus SMoSe are believed to produce these distinct optical properties. By estimating the optical absorption of the intrinsic dipoles and tracing their dependence on the light incident angles, we speculate that the dipoles are not perpendicularly aligned to the in-plane direction of the monolayer, but rather tilted by a small angle between 0° and 10°.

Abstract
Fully internal and motional state controlled and individually manipulable polar molecules are desirable for many quantum science applications leveraging the rich state space and intrinsic interactions of molecules. While prior efforts at assembling molecules from their constituent atoms individually trapped in optical tweezers achieved such a goal for exactly one molecule (Zhang J T et al 2020 Phys. Rev. Lett.

370 331–5), here we extend the technique to an array of five molecules, unlocking the ability to study molecular interactions. We detail the technical challenges and solutions inherent in scaling this system up. With parallel preparation and control of multiple molecules in hand, this platform now serves as a starting point to harness the vast resources and long-range dipolar interactions of molecules.

Published: April 2022

Abstract
Auxetic materials showing a negative Poisson’s ratio can offer unusual sensing capabilities due to drastic percolation changes. This study presents the capacitive response of wet-fractured carbon nanotube paper composites in exposure to humidity. A strained composite strip is fractured to produce numerous cantilevers consisting of cellulose fibers coated with carbon nanotubes. During stretching, the thin composite buckles in the out-of-plane direction, which causes auxetic behavior to generate the radially structured electrodes. The crossbar junctions forming among the fractured electrodes significantly increase capacitance and its response to humidity as a function of sensor widths. The molecular junctions switch electric characteristics between predominantly resistive- and capacitive elements. The resulting capacitive response is characterized for humidity sensing without the need for an additional absorption medium. The normalized capacitance change (ΔC/C0) exhibits a sensitivity of 0.225 within the range of 40 ∼ 80% relative humidity. The novel auxetic behavior of a water-printed paper-based nanocomposite paves the way for inexpensive humidity and sweat sensors.

Abstract
In insects, insulin signaling plays a pivotal role in the regulation of growth, metabolism, reproduction, and aging. Revealing the regulatory roles of insulin signaling in natural enemy insects is helpful for developing artificial approaches to promote reproduction. In this study, the expression of four insulin-like peptides (ILPs) in female adults of the natural predator Chrysopa pallens was analyzed by quantitative real-time-polymerase chain reaction (qRT-PCR) and their functions were investigated by RNA interference (RNAi). C. pallens ILP1 (CpILP1) and C. pallens ILP4 (CpILP4) showed a gradual increase in mRNA levels from early adult stages to later stages. However, C. pallens ILP2 (CpILP2) and C. pallens ILP3 (CpILP3) had an opposite expression curve with a high transcript level at the beginning of the adult stage and a gradual reduction thereafter. All four CpILPs showed high expression levels in the ovary, but CpILP2 transcripts were also abundant in fat bodies. Disruption of CpILP1 and CpILP2 expression by RNAi-mediated knockdown strikingly suppressed ovarian development and reduced C. pallens vitellogenin gene 1 (CpVg1) transcripts. Depletion of CpILP3 transcripts did not significantly decrease ovariole number but drastically reduced CpVg1 expression. Interference with the expression of CpILP4 significantly inhibited ovarian development but did not suppress CpVg1 expression. All gene knockdowns failed to dramatically impair total fecundity and egg quality. These data suggest that the four C. pallens ILPs are involved in reproductive signaling at different degrees.
Total Energy Intake: Implications for Epidemiologic Analyses
Authors: McCullough Lauren E , Byrd Doratha A 
Published: April 2022

Abstract
In 1986, Willett and Stampfer (Am J Epidemiol. 1986;124(1):17–27) propelled the nutritional epidemiology field forward by publishing a commentary emphasizing the importance of analyzing diet in relation to total energy intake in epidemiologic analyses of diet and disease, detailing the value of accounting for body size, physical activity, and metabolic efficiency in diet-disease analyses via energy intake adjustment. Their publication has since been cited over 2,886 times and has inarguably advanced methodology for studying diet-disease associations, with most nutritional epidemiology studies standardly including some form of energy adjustment. However, there remains debate regarding the best scenarios and methods for energy adjustment. The goals of this commentary are to provide an updated review on factors that account for interindividual differences in energy intake, provide a balanced discussion regarding the considerations for or against adjustment for energy intake, and provide an updated examination of the commonly employed methods for the analysis of nutrient-disease associations. The principles of energy adjustment continue to be relevant nearly 25 years later, as it remains a critical method to account for potentially confounding interindividual variations in body size and physical activity.

Published: April 2022

AbstractChronic traumatic encephalopathy (CTE) is a neurodegenerative disease associated with exposure to repetitive head impacts such as those from American football. Our understanding of this association is based on research in autopsied brains, since CTE can only be diagnosed postmortem. Such studies are susceptible to selection bias, which needs to be accounted for to ensure a generalizable estimate of the association between repetitive head impacts and CTE. We evaluated the relationship between level of American football playing and CTE diagnosis after adjusting for selection bias. The sample included 290 deceased male former American football players who donated their brains to the Veterans Affairs–Boston University–Concussion Legacy Foundation (VA-BU-CLF) Brain Bank between 2008 and 2019. After adjustment for selection bias, college-level and professional football players had 2.38 (95% simulation interval (SI): 1.16, 5.94) and 2.47 (95% SI: 1.46, 4.79) times the risk of being diagnosed with CTE as high-school–level players, respectively; these estimates are larger than estimates with no selection bias adjustment. Since CTE is currently diagnosed only postmortem, we additionally provide plausible scenarios for CTE risk ratios for each level of play during the former players’ lifetime. This study provides further evidence to support a dose-response relationship between American football playing and CTE.
Indemnification, Monitoring, and Competition: Evidence from R&D Contracts
Authors: Guo Di , Hua Xinyu , Jiang Kun 
Published: April 2022

Abstract
This article examines the adoption of indemnification clauses in research and development (R&D) contracts, in which a firm commits to reimbursing its agent against liabilities and legal costs. Indemnification achieves efficient risk sharing but dilutes the agent’s incentives to take precautions. Such incentives may be restored if the firm offers contingent indemnification and monitors the agent’s activities. Additionally, tougher competition can motivate the firm and agent to take more aggressive R&D activities, which leads to higher liability risks. We show that the optimal contract is more likely to include an indemnification clause when monitoring is more effective and market competition is tougher. By investigating R&D agreements between pharmaceutical firms and biotech agents, we find relevant empirical observations. We also observe a positive correlation between the use of indemnification clauses and the use of termination rights that allow firms to terminate projects without cause.
Gig Economy Teaching: On the Importance and Dangers of Self-branding in Online Markets
Authors: Curran Nathaniel Ming , Jenks Christopher 
Published: April 2022

Abstract
The gig economy is rapidly transforming service-based industries, including online teaching. Even before the COVID-19 pandemic forced millions of people worldwide to work remotely, gig economy teaching generated billions of dollars in revenue and was responsible for millions of lessons per month. Although the global labor market is currently experiencing a major shift because of the gig economy, applied linguists have paid little attention to gig-based work and its implications. The current study narrows this research gap by using self-branding theories to understand the ways in which gig economy teachers market themselves to potential students. The findings, which are based on 100 teacher profiles, reveal that teachers adopt four self-branding discourses when marketing their teaching services. These self-branding discourses may vary according to the teacher’s country of origin, professional qualifications, and first language background. The study argues that self-branding discourses reflect a larger, and perhaps more problematic, global trend in which individual workers directly compete against each other in a race to lower earnings and job security.
