Approximation and analysis of transient responses of a reverberation chamber by pulsed excitation
Authors: Pasche Konstantin , Ossevorth Fabian , Jacobs Ralf T. 
Published: December 2020

Abstract. Reverberation chambers show transient behaviour when excited with a pulsed signal. The field intensities can in this case be significantly higher than in steady state, which implies that a transient field can exceed predefined limits and render test results uncertain. Effects of excessive field intensities of short duration may get covered and not be observable in a statistical analysis of the field characteristics. In order to ensure that the signal reaches steady state, the duration of the pulse used to excite the chamber needs to be longer than the time constant of the chamber. Initial computations have shown that the pulse width should be about twice as long as the time constant of the chamber to ensure that steady state is reached. The signal is sampled in the time domain with a sampling frequency according to the Nyquist theorem. The bandwidth of the input signal is determined using spectral analysis. For a fixed stirrer position, the reverberation chamber, wires, connectors, and antennas can jointly be considered as a linear time-invariant system. In this article, a procedure will be presented to extract characteristic signal properties such as rise-time, transient overshoot and the mean value in steady state from the system response. The signal properties are determined by first computing the envelope of the sampled data using a Hilbert transform. Subsequent noise reduction is achieved applying a Savitzky–Golay filter. The point where steady state is reached is then computed from the slope of the envelope by utilising a cumulative histogram. The spectral analysis is not suitable to examine the transient behaviour and determine the time constants of the system. These constants are computed applying the method of Prony, which is based on the estimation of a number of parameters in a sum of exponential functions. An alternative to the Prony Method is the Time-Domain Vector-Fit method. In contrast to the first mentioned variant, it is now also possible to determine the transfer function of the overall RC system. Differences and advantages of the methods will be discussed.
Utilization and Reimbursement Trends Based on Certificate of Need in Single-level Cervical Discectomy
Authors: Ziino Chason , Bala Abiram , Cheng Ivan 
Published: December 2020

Objective:
To compare utilization and reimbursement for cervical discectomy in certificate of need (CON) and non-CON states.

Summary of Background Data:
Cervical discectomy is a commonly performed procedure, but little is known about utilization and reimbursement patterns in the CON setting.

Introduction:
Cervical discectomy is increasingly used and remains effective. Increasing healthcare costs have led to decreased reimbursement and a push toward outpatient procedures. CON programs were established to ensure that expansion of medical facilities were within acceptable use; however, the literature on their impact in spine surgery is limited. The purpose of this study was to examine the impact of CON status on both reimbursement and utilization in cervical decompression in both inpatient and outpatient settings.

Methods:
We analyzed a private payer and Medicare database from 2007 to 2015. All single-level cervical discectomies were selected then split into CON and non-CON states. Each group was then further split into inpatient and outpatient. Utilization and reimbursement were analyzed using the compound annual growth rate (CAGR), with reimbursement adjusted by the US Bureau of Labor Statistics Consumer Price Index.

Results:
We identified 1,580 single level cervical decompressions in our study period: 888 were done in the inpatient setting, whereas 692 were done in the outpatient setting. Adjusted reimbursement only increased in the non-CON outpatient setting, with a CAGR of 2.0%. All other settings had decreased reimbursement. Utilization increased across all four settings, with the highest growth seen in the CON outpatient setting, with a CAGR of 12.7%. The highest average reimbursement was in the non-CON outpatient setting at $4,237.

Discussion:
Cervical discectomy is seeing increased utilization most rapidly in the outpatient setting, although reimbursement is declining with the exception of procedures done in the non-CON outpatient setting. Surgeons should be aware of these trends in the changing healthcare economic climate.

Study Design:

La empleabilidad a debate: ¿qué sabemos sobre la empleabilidad como estrategia de cambio social?
Authors: Llinares Insa Lucía , Córdoba-Iñesta Ana Isabel , González-Navarro Pilar 
Published: December 2020

Los cambios en mundo laboral derivados de la globalización y el neoliberalismo han puesto a la empleabilidad en el centro de atención del desarrollo económico y social. Sin embargo, la falta de consenso en las teorías y las dimensiones que la definen reclaman un análisis de la investigación que permita su uso como estrategia de cambio social. El objetivo de este trabajo es realizar una revisión sistemática de los marcos teóricos sobre empleabilidad. Se ha realizado un análisis de 239 artículos científicos atendiendo a dos áreas temáticas: la historia del concepto y las perspectivas teóricas. Los resultados de esta revisión han permitido sistematizar y comprender las orientaciones teóricas desde las que se ha analizado la empleabilidad, las premisas que toman las diferentes teorías como punto de partida y los indicadores propuestos. A partir de todo ello, se han abierto algunas cuestiones para la reflexión de los agentes sociales vinculados a la educación, la acción social y al empleo.
Fostering knowledge building in learning by teaching: A test of the drawing‐facilitates‐explaining hypothesis
Authors: Fiorella Logan 
Published: December 2020

SummaryLearning by teaching can be effective, yet many students fail to engage in knowledge building, in which they actively generate inferences and connect the material to their existing knowledge. Recent research suggests creating drawings while orally explaining to others fosters knowledge building and long‐term learning; however, the mechanisms underlying this effect—generation, visualization, or both—remain unclear. In the present study, college students will learn about the human respiratory system and then explain what they learned on video to a fictitious peer. Following a 2 × 2 between‐subjects design, students will either generate their own words or visuals on a whiteboard while explaining aloud, or they will view instructor‐provided words or visuals while explaining aloud. We expect access to visuals (generated or provided) will foster knowledge building and learning outcomes better than access to words. We will also test competing hypotheses regarding potential unique benefits of explaining instructor‐provided versus learner‐generated visuals.
Discriminating deceptive from truthful statements using the verifiability approach: A meta‐analysis
Authors: Verschuere Bruno , Bogaard Glynis , Meijer Ewout 
Published: December 2020

AbstractThe Verifiability Approach predicts that truth tellers will include details that can be verified by the interviewer, whereas liars will refrain from providing such details. A meta‐analysis revealed that truth tellers indeed provided more verifiable details (k = 28, d = 0.49, 95% CI [0.25; 0.74], BF10 = 93.28), and a higher proportion of verifiable details (k = 26, d = 0.49 95% CI: 0.25, 0.74, p < .001, BF10 = 81.49) than liars. We found no evidence that liars would include more unverifiable details than truth tellers (k = 20, d = −0.31, 95% CI [−0.02; 0.64], BF10 = 1.12) Moderator analysis revealed the verifiable detail effect was substantially larger when the statement is the suspect's alibi, but smaller when an incentive to appear credible was used. Our findings support the main prediction behind the Verifiability Approach, but also stress the need for larger sample sizes and independent replications.
Beyond the emergency department: Effects of COVID‐19 on emergency medicine resident education

Published: December 2020

AbstractBackgroundIn December 2019, a novel coronavirus (COVID‐19) caused widespread clinical disease, triggering limited in‐person gatherings and social‐distancing guidelines to minimize transmission. These regulations led most emergency medicine (EM) residency training programs to rapidly transition to virtual didactics. We sought to evaluate EM resident perceptions of the effects of COVID‐19 on their didactic and clinical education.MethodsWe performed a cross‐sectional survey study at seven EM residency programs using a mixed‐methods approach designed to understand resident perceptions regarding the impact of COVID‐19 on their educational experience. Quantitative data were presented as percentages with comparison of subgroups, while open‐ended responses were analyzed using qualitative methodology.ResultsWe achieved a 59% response rate (187/313). The majority of respondents (119/182, 65.4%) reported that the COVID‐19 pandemic had a negative impact on their residency education with junior residents disproportionately affected. A total of 81 of 182 (44.5%) participants reported that one or more of their clinical rotations were partially or completely canceled due to the pandemic. Additionally, we identified four themes and 34 subthemes highlighting the contextual effects of the pandemic, which were then divided into positive and negative influences on the residency experience. The four themes include systems experience, clinical experience, didactic experience, and wellness.ConclusionOur study examined the impact of COVID‐19 on residents’ educational experiences. We found overall mixed responses with a slightly negative impact on residency education, wellness, and clinical rotations, while satisfaction with EM as a career choice was increased. Factors influencing this included systems, clinical, and didactic experiences as well as overall wellness.

PremiseLarge disjunctions in species distributions provide excellent opportunities to study processes that shape biogeographic patterns. One such disjunction is the eastern Asia–eastern North America (EA‐ENA) floristic disjunction. For many genera with this disjunction, species richness is greater in EA than in ENA; this pattern has been attributed, in part, to higher rates of molecular evolution and speciation in EA. Longer branch lengths have been found in some EA clades, relative to their ENA sister clades, suggesting that the EA lineages have evolved at a higher rate, possibly due to environmental heterogeneity, potentially contributing to the species richness anomaly.MethodsTo evaluate whether rates of molecular evolution are elevated in EA relative to ENA, we used transcriptomes from species in 11 genera displaying this disjunction. Rates of molecular evolution were estimated for up to 385 orthologous nuclear loci per genus.ResultsNo statistically significant differences were identified in pairwise comparisons between EA and ENA sister species, suggesting equal rates of molecular evolution for both species; the data also suggest similar selection pressures in both regions. For larger genera, evidence likewise argues against more species‐rich clades having higher molecular evolutionary rates, regardless of region. Our results suggest that genes across multiple gene ontology categories are evolving at similar rates under purifying selection in species in both regions.ConclusionsOur data support the hypothesis that greater species richness in EA than ENA is due to factors other than an overall increase in rates of molecular evolution in EA.
Dangers in the dark: Calling for a safer practice of transvaginal ultrasonography
Authors: Collins Kelly , Hamlyn Tina , Bruxner George , Kothari Alka 
Published: December 2020

AbstractBackgroundThe intimate examination is an important component of the assessment of a patient presenting with obstetric or gynaecological concerns. Ultrasound practitioners, like any other medical practitioner, are in a unique and privileged position. During the examination, the sonographers engage in a very close and personal interaction with an individual whom they have likely never met. They are also most likely unfamiliar with their social situation, cultural background, previous experiences with the healthcare profession and more importantly, any history of sexual trauma. It is an extremely sensitive area of practice which places a great deal of responsibility on the clinician to ensure that they not only protect their patient from psychological distress, but also themselves, from the threat of litigation arising from such distress.AimsThis paper highlights the current governance requirements for sonographers and makes suggestions to support them in safeguarding their patients and themselves from allegations of unprofessional conduct, until such a regulatory body exists.Materials and MethodsA wide‐ranging review of the literature exploring the perceptions of female patients regarding intimate sonographic examination was performed using standard search engines. Additionally, grey literature was searched for policy statements and government regulatory documents for guidance on the topic.ResultsAlthough much research has been undertaken in this field across diverse cultures and knowledge in this area is ever increasing; however, the guidelines for sonographers appear to be site specific and variable. At present, there is no overarching governance for sonographers, as there is with practitioners registered with the Australian Health Practitioner Regulation Agency.DiscussionWhile there are practice standards for the purposes of Medicare set out by the Diagnostic Imaging Accreditation Scheme, there is no regulatory professional standard that sonographers are held accountable to. This is problematic and has the potential for inadvertent boundary transgression by the practitioner, as there is also no existing framework for management of such incidents in an equitable manner.ConclusionThe intimate examination is generally well tolerated; however, there is a subset of the population who are vulnerable to psychological distress arising from the examination. The sonographer must be astute to signs of distress and act in accordance with the intimate examination guidelines set out by AHPRA, for the dual purpose of protecting their patients against harm and also themselves from the threat of litigation.
Biofabricated 3D in vitro model of fibrosis‐induced abnormal hepatoblast/biliary progenitors' expansion of the developing liver

Published: December 2020

AbstractCongenital disorders of the biliary tract are the primary reason for pediatric liver failure and ultimately for pediatric liver transplant needs. Not all causes of these disorders are well understood, but it is known that liver fibrosis occurs in many of those afflicted. The goal of this study is to develop a simple yet robust model that recapitulates physico‐mechanical and cellular aspects of fibrosis mediated via hepatic stellate cells (HSCs) and their effects on biliary progenitor cells. Liver organoids were fabricated by embedding various HSCs, with distinctive abilities to generate mild to severe fibrotic environments, together with undifferentiated liver progenitor cell line, HepaRG, within a collagen I hydrogel. The fibrotic state of each organoid was characterized by examination of extracellular matrix (ECM) remodeling through quantitative image analysis, rheometry, and qPCR. In tandem, the phenotype of the liver progenitor cell and cluster formation was assessed through histology. Activated HSCs (aHSCs) created a more severe fibrotic state, exemplified by a more highly contracted and rigid ECM, as well higher relative expression of TGF‐β, TIMP‐1, LOXL2, and COL1A2 as compared to immortalized HSCs (LX‐2). Within the more severe fibrotic environment, generated by the aHSCs, higher Notch signaling was associated with an expansion of CK19+ cells as well as the formation of larger, more densely populated cell biliary like‐clusters as compared to mild and non‐fibrotic controls. The expansion of CK19+ cells, coupled with a severely fibrotic environment, are phenomena found within patients suffering from a variety of congenital liver disorders of the biliary tract. Thus, the model presented here can be utilized as a novel in vitro testing platform to test drugs and identify new targets that could benefit pediatric patients that suffer from the biliary dysgenesis associated with a multitude of congenital liver diseases.
