Authors: Casallas Jhoan S. , Parra-Peñuela Hector Guillermo , Gaona Elvis E. 
Published: March 2023

Context: Wind energy sources utilize renewable, free, and environmentally friendly resources, so there are projects focused on the design of wind turbines to increase their efficiency. Simulations using computational fluid dynamics techniques allow designs to be analyzed. which, are then validated through experimentation and wind tunnel measurements.
Method: Data acquisition is performed by using Wind Sensor Rev.P sensors to measure wind velocity, and MMA7361 accelerometer to measure the vibrations generated by the wind in the turbine. Additionally, an ESP32 is required to process and transmit the data via Bluetooth, thus facilitating the installation of the real-time monitoring module inside the wind tunnel.
Results: A monitoring module with a sampling rate of 5 ms was obtained, thus allowing real-time data acquisition, with a resolution of 12 bits for good data capturing accuracy and a transmission rate of approximately 74000 bps. An application capable of plotting 3D acceleration and 2D wind speed signals was also created.
Conclusions: The device developed serves as a support for future wind turbine design projects since it is wireless, its installation is simple, it facilitates data collection inside a wind tunnel, and it allows visualizing the turbine’s behavior in real time by means of a graphic interface.

Published: March 2023

AbstractPreclinical research remains the essential platform in the development and optimization of medical therapies and advancements in translational medicines. However, specifically to animal research, federal laws, and institutional policies require investigators to apply the principles of the 3R's (replacement, reduction, and refinement). The concept of benchtop models utilizing isolated organs, in which multiple variables can be controlled to recreate human function, has been innovative advancements in preclinical research models that adhere to these principles. More specifically, isolated perfused kidney (IPK) models have been invaluable preclinical tools that have led to numerous advancements over the decades, including understanding renal physiology, pharmacologic therapies, and improvements in renal transplantation. However, pre‐existing IPK models are not without their own limitations, leaving areas for improvement. An isolated perfused kidney apparatus was designed to best recreate human use conditions as a preclinical tool. Porcine renal blocks were chosen over the more commonly used rodent models, due to their greater similarities to human anatomies. Sixteen porcine kidney pairs obtained en bloc were extracted and placed onto an apparatus where aortic flows, pressures, and overall systemic temperatures were controlled. Organ viability was assessed in 10 renal blocks (n = 8 fresh and n = 2 previously frozen specimens) via both urinary flows and compositions at timepoints up to 180 min. Multimodality imaging, which included fluoroscopy, ultrasound, optical coherence tomography (OCT), and video scopes, was also employed to capture internal and external images to determine renal artery orientations and dimensions. Anatomical measurements and viability assessments of porcine renal blocks were successfully achieved in our perfusion model. Renal main artery diameters averaged smaller in our sample size than in human anatomy while also having more superior takeoff angles. Yet, the average lengths of each main segment were comparable to human anatomy: 32.09 ± 7.97 mm and 42.23 ± 7.33 mm in the left and right renal main artery, respectively. Urine production and urine composition of the fresh renal blocks, when compared to the frozen blocks and baseline perfusate, showed kidney viabilities of up to 3 h via excretion and retention of various metabolites. In this paper, we described a protocol for an isolated perfused kidney apparatus using large mammalian renal blocks. We believe this protocol to be an improvement from similar pre‐existing models in better representing human physiologic function while allowing for multimodal imaging. The resulting Visible Kidney™ preclinical model, which has shown viability after isolation and reperfusion, can be a fast and reliable tool for the development of medical devices while also reducing the unnecessary use of animals for research.

Published: March 2023

Abstract
Primary thyroid adenoid cystic carcinoma (PTACC) is an extremely rare type of mucin-secreting adenocarcinoma. Currently, it is difficult to diagnose, and it lacks standard treatment protocols. We report the case of a 53-year-old female patient with PTACC who underwent additional intensity-modulated radiotherapy 1 month after surgical treatment with an uneventful course. No invasion or distant metastasis was detected at the 7-month follow-up after radiotherapy, and the prognosis was favorable. In this case, herein, we have summarized the diagnostic features of the disease and proposed that postoperative adjuvant radiotherapy can significantly improve the patient’s prognosis. Finally, we further confirmed the important role of radiotherapy in PTACC by reviewing relevant literature, which may provide clinicians with valuable treatment experience.
Ageing bodies and beauty in selected Polish women’s magazines
Authors: Kociołek Katarzyna 
Published: March 2023

Abstract
The aim of the article is to examine the representation of ageing in selected issues of the Polish women’s magazine Twój Styl. With reference to Wolf’s concept of the “beauty myth,” the article argues that ageing is presented as a threat to women’s psychological integrity. Although the theme of old age is rarely directly addressed in the magazines, its presence is implied in the advertised anti-age beauty products. Based on semiotic theory and Cognitive Metaphor Theory, the paper demonstrates that the advertising of anti-ageing beauty products serves the function of controlling ageing female bodies, which are positioned outside of the mainstream concept of femininity.
Paint Pigment on Epigraphic Squeezes: A Case-Study from the Etruscological Collections of Olof August Danielsson
Authors: Burman Annie 
Published: March 2023

Abstract
The practice of wet squeezing as a means of creating epigraphic facsimiles was widespread during the 19th and 20th centuries, but often negatively impacted the original inscriptions, particularly in cases where paint pigment was present. Depending on the precise method used, the pigment may transfer from the original to the squeeze. This article presents a case-study of four such squeezes made by Swedish Etruscologist Olof August Danielsson in 1886 of a funerary tile from Chiusi, as part of the preparatory work for Corpus Inscriptionum Etruscarum. This material makes it possible to study epigraphic polychromy in cases where pigment on the original has been damaged through squeezing. In addition, it illustrates how squeezes can give insight into the history of individual objects, as the squeezes, which show both the carving and the paint, cast light on the various proposed readings of the tile’s Etruscan inscription (CIE 1973/ET Cl 1.1478).
California Hospitals’ Rapidly Declining Traditional Medicare Operating Margins
Authors: Gaudette Étienne , Bhattacharya Jay 
Published: March 2023

Abstract
In recent years, Medicare margins of U.S. short-term acute care hospitals participating in the inpatient prospective payment system (IPPS) have declined nationally by over 10 percentage points, from 2.2% in 2002 to −8.7% in 2019. This trend conceals critical regional variations, with recent studies documenting particularly low and negative margins in metropolitan areas with higher labor costs despite geographic adjustments by the Centers for Medicare & Medicaid Services (CMS). In this article, we describe recent trends in California hospitals’ traditional fee-for-service Medicare operating margins compared to hospital operating margins across payers and changes in the CMS hospital wage index (HWI) used to adjust Medicare payments. We conduct an observational study of audited financial reports of IPPS-participating California hospitals using California Department of Health Care Access and Information and CMS data for years 2005–2020 (n = 4429 reports included in the analysis). We describe trends in financial measures by payer and investigate associations between HWI and traditional Medicare margins, focusing on the pre-COVID period of 2005 through 2019. During that period, California hospitals’ statewide traditional Medicare operating margin declined from −27 to −40%, and financial shortfalls in caring for fee-for-service Medicare patients more than doubled ($4.1 billion in 2005 to $8.5 billion in 2019, both values in 2019 dollars). Meanwhile, operating margins from commercial managed care patients increased from 21% in 2005 to 38% in 2019. There was a stable negative association between HWI and traditional Medicare operating margins throughout the period (p = 0.000 in 2005; p < 0.0001 in 2006–2020), indicating that areas of California with higher health care wages had persistently worse traditional Medicare operating margins than areas with lower wages.
Using imagery to build confidence in esports
Authors: Vealey Robin , Wright Emily 
Published: March 2023

Abstract
The purpose of this article is to provide strategies for using imagery to build confidence in esport athletes. Because confidence is a belief and strongly influenced by success and failure, mental training using imagery should be designed to create and sustain an agile mindset to accept events that shake confidence and enable athletes to respond productively to adapt and restore self-belief. Esport athletes should start small with short but frequent sessions of polysensory imagery practice of simple skills and strategies to build imagery skill and confidence. Imagery practice should be similar to competition, in terms of physical posture, setting, and equipment. Confidence-building imagery strategies include creating and rehearsing optimal performance plans as well creating imagery scripts for productive responses to mistakes, losing, tilting, and worrying about the skills and decision-making of teammates. Uses of imagery can be periodized to optimally develop confident performance and responses, prepare for specific opponents or tournaments, and assess prior performances using a growth mindset to enhance self-belief.
Temporally Local Maximum Likelihood with Application to SIS Model
Authors: Gourieroux Christian , Jasiak Joann 
Published: March 2023

AbstractThe parametric estimators applied by rolling are commonly used for the analysis of time series with nonlinear patterns, including time varying parameters and local trends. This paper examines the properties of rolling estimators in the class of temporally local maximum likelihood (TLML) estimators. We consider the TLML estimators of (a) constant parameters, (b) stochastic, stationary parameters and (c) parameters with the ultra-long run (ULR) dynamics bridging the gap between the constant and stochastic parameters. We show that the weights used in the TLML estimators have a strong impact on the inference. For illustration, we provide a simulation study of the epidemiological susceptible–infected–susceptible (SIS) model, which explores the finite sample performance of TLML estimators of a time varying contagion parameter.
Engineering isospectrality in multidimensional photonic systems
Authors: Lee Dayeong , Park Hyungchul , Yu Sunkyu 
Published: March 2023

Abstract
Selective manipulation of energy levels plays an essential role in realizing multichannel wave devices. One of the representative examples is to utilize the concept of quasi-isospectrality: a family of wave systems with an almost identical spectrum except for a part of energy levels. Most approaches toward quasi-isospectrality have employed analytical methods based on symmetry or tridiagonalization, such as supersymmetry, Householder, or Lanczos transformations. Although such analytical approaches provide deterministic and stable designs based on operator factorizations, the mathematical strictness in the factorizations, at the same time, hinders isospectral engineering in a given multidimension. Here we develop the semi-analytical method for engineering isospectrality in multidimensional photonic systems. The method provides the systematic perturbation for the target energy level shifts by decomposing the allowed form of system changes into the perturbation basis. We demonstrate the isospectrality of lower-, higher-, and random-order states while imposing the designed shifts on the other states. The stability analysis shows that the accuracy of the method is determined by the ranges of isospectral state numbers and perturbation strength. The systematic, free-form, and multidimensional natures of the proposed method show great potential for the platform-transparent design of multichannel devices.

Development of variotherm extrusion blow molding technology to produce high-gloss automotive spoilers
Authors: Xiao Cheng-Long , Hopmann Christian , Kahve Cemi E. 
Published: March 2023

Abstract
The surface quality of plastic parts produced by the conventional extrusion blow molding (EBM) process is usually poor, especially for those made of engineering thermoplastics. To achieve a high-gloss appearance, some costly and pollutive post-treatments (e.g., painting, polishing, etc.) have to be employed to hide or eliminate surface defects. Herein, a variable mold temperature EBM (i.e., variotherm EBM) technology with electric heating and water cooling, which has the potential to directly yield high-gloss parts, was developed. First, the process principle was designed and presented. Then, an complex industrial plastic part, i.e., automotive spoiler, was selected as a molding case to be studied, in which the variotherm blow mold of the spoiler was designed and especially the design rationality of the mold electric-heating and cooling systems was then examined by numerically evaluating the mold thermal response in the respect of cavity surface heating/cooling efficiencies and uniformity. Finally, the variotherm EBM experiments based on the manufactured prototype spoiler mold were conducted. The results showed that the developed technology can realize high-temperature blow molding with both the molding cycle time and energy consumption in an acceptable range compared with the conventional EBM. Moreover, the surface quality of the molded spoilers is largely improved and the surface defects that are generally appearing in the conventional EBM process can be fully eliminated. Thus, the feasibility and effectiveness of developed technology in yielding high-gloss blow-molded parts are demonstrated.
The Mobility of Neurofilaments in Mature Myelinated Axons of Adult Mice
Authors: Fenn J. Daniel , Li Yinyun , Julien Jean-Pierre , Jung Peter , Brown Anthony 
Published: March 2023

AbstractStudies in cultured neurons have shown that neurofilaments are cargoes of axonal transport that move rapidly but intermittently along microtubule tracks. However, the extent to which axonal neurofilaments movein vivohas been controversial. Some researchers have proposed that most axonally transported neurofilaments are deposited into a persistently stationary network and that only a small proportion of axonal neurofilaments are transported in mature axons. Here we use the fluorescence photoactivation pulse-escape technique to test this hypothesis in intact peripheral nerves of adult malehThy1-paGFP-NFMmice, which express low levels of mouse neurofilament protein M tagged with photoactivatable GFP. Neurofilaments were photoactivated in short segments of large, myelinated axons, and the mobility of these fluorescently tagged polymers was determined by analyzing the kinetics of their departure. Our results show that >80% of the fluorescence departed the window within 3 h after activation, indicating a highly mobile neurofilament population. The movement was blocked by glycolytic inhibitors, confirming that it was an active transport process. Thus, we find no evidence for a substantial stationary neurofilament population. By extrapolation of the decay kinetics, we predict that 99% of the neurofilaments would have exited the activation window after 10 h. These data support a dynamic view of the neuronal cytoskeleton in which neurofilaments cycle repeatedly between moving and pausing states throughout their journey along the axon, even in mature myelinated axons. The filaments spend a large proportion of their time pausing, but on a timescale of hours, most of them move.

Aproximaciones temáticas de los estudios ambientales sobre la actividad artesanal: argumentos para su estudio en México
Authors: Farfán Escalera Ricardo , Pérez-Ramírez Carlos Alberto , Romero Aguilar Mariana 
Published: March 2023

Introducción: Las diferentes vertientes que puede tomar el estudio de la actividad artesanal y su relación con el medio natural han representado un importante reto debido a la diversidad de pensamientos expresados, lo que conlleva un esfuerzo heurístico para identificar elementos explicativos que tuviesen puntos de encuentro suficientes y permitieran establecer una clasificación pertinente.
Objetivo: La investigación tuvo como objetivo documentar las orientaciones temáticas que enmarcan los estudios ambientales de la actividad artesanal, esto mediante la revisión de distintas investigaciones que han abordado la relación entre artesanía y naturaleza.
Método: Para ello, se llevó a cabo un análisis crítico del acervo bibliográfico identificando las orientaciones temáticas. La indagación se realizó tras el estudio de artículos científicos publicados en revistas indizadas, durante el periodo 2007 a 2022 y disponibles en acceso abierto en idioma español, inglés y portugués; además se consideraron los siguientes criterios: tipo de investigación, objetivo de la contribución, enfoque metodológico, ámbito territorial, orientación temática y disciplinaria.
Resultados: Se identificaron cuatro grupos de aproximaciones temáticas: a) proceso de producción, acceso a materias primas, transformación y tecnologías; b) impacto de la producción sobre los recursos naturales; c) formas de organización social en el contexto local; d) comercialización y consumo en el mercado actual.
Conclusiones: Si bien es posible establecer una propuesta de clasificación de los estudios ambientales de las artesanías, se requiere una visión ampliada de la realidad que supere las perspectivas parcelarias, y se consideren los paradigmas propios de la complejidad como argumentos para su estudio en México.
