Despite the important hydrological and ecological implications of the snowpack, its real time monitoring remains challenging. This is particularly relevant in relation to the Snow Water Equivalent ...(SWE), as the available technologies which measure it, exhibit a number of limitations that hinder their operational implementation. In this work, we explore the potential of a new technology, Muon Scattering Radiography, to infer the SWE. We coupled snowpack simulations generated by the SNOWPACK model, with a muon scattering simulation program based on GEANT4. The SWE is modeled as a function of the muon scattering distributions. Predictions of the SWE along the year are provided showing a root‐mean‐square error of 12 mm for 5 hr continuous measurements. We also performed laboratory measurements using ice samples, confirming the SWE estimation capabilities and the potential of the technique to operate as a SWE monitoring tool.
Plain Language Summary
The monitoring of the seasonal snowpack is important to understand and predict the dynamics of the hydrological and ecological processes, but its continuous monitoring is still a scientific challenge. Particularly in relation to the Snow Water Equivalent (SWE). The available technologies to monitor the SWE exhibit a number of limitations that prevent its use in many real world cases. Here we explore the potential of a new technology, Muon Scattering Radiography (MSR), to quantify the SWE. MSR is a technique based in the detection of the natural and innocuous radiation of muon particles. The technique consists in the measurement of muon deviations, which are larger when the muons cross very large or dense materials. In this analysis, we simulated the snowpack evolution itself and its measurement process. Then, we determined the relation between muon deviations and SWE. Finally, we estimated the precision in the determination of SWE comparing the predictions to the ground truth in simulation. The results yielded a precision of about 12 mm. We also performed laboratory measurements with ice samples, using a 4 layer muon detector based on multiwire proportional chambers, confirming the potential of the technique to operate as a SWE monitoring tool.
Key Points
We test the suitability of Muon Scattering Radiography to infer the Snow Water Equivalent (SWE)
Numerical simulations show the technique can estimate the SWE with a precision of around 12 mm
Laboratory measurements confirm the results obtained with simulation
La sociología de las plataformas ha señalado que la consolidación de los modelos de negocio online se apoya en el establecimiento de un vínculo específico entre una cultura de consumo cada vez más ...individualizada, y una actividad laboral configurada y gestionada por las plataformas en su propio beneficio. Esta tesis, sin embargo, no tiene en cuenta el papel de los sistemas de valoración por ratings y rankings en la relación entre consumo y trabajo. En este artículo mostramos que ratings y rankings median el vínculo entre consumo y trabajo, estableciendo específicas asimetrías de información y relaciones de poder y dependencia entre ellos y con la plataforma. Además, en determinadas condiciones, el sistema de rating y rankings permite a los trabajadores elaborar estrategias de resistencia al algoritmo y rediseñar su relación con el consumidor.
Extra virgin olive oil (EVOO) is a cornerstone of the Mediterranean diet (MedD). In this narrative review, we synthesize and illustrate the various characteristics and clinical applications of EVOO ...and its components-such as oleic acid, hydroxytyrosol, and oleuropein-in the field of clinical nutrition and dietetics. The evidence is split into diet therapy, oleic acid-based enteral nutrition formulations and oral supplementation formulations, oleic acid-based parenteral nutrition, and nutraceutical supplementation of minor components of EVOO. EVOO has diverse beneficial health properties, and current evidence supports the use of whole EVOO in diet therapy and the supplementation of its minor components to improve cardiovascular health, lipoprotein metabolism, and diabetes mellitus in clinical nutrition. Nevertheless, more intervention studies in humans are needed to chisel specific recommendations for its therapeutic use through different formulations in other specific diseases and clinical populations.

Abstract
Conversation about the current and potential effects of digital technologies on the nature of work is raging within scholarly and practitioner communities. Artificial intelligence, robotics, ...data analytics, digital platforms, and automation, among other technologies, are prompting a swift and profound transformation of work. Building on Pierpaolo Donati's relational sociology, we examine the changes these technologies are likely to bring about in work as a human relation. Despite the very real threats of unemployment, job insecurity, precariousness, and surveillance, technology may also encourage the emergence of a work culture that shifts the scales toward a relational realm rather than a transactional one. To this end, we argue that work should be understood as a social relation with four dimensions: exchange value, intrinsic extra‐economic purpose, communication for reciprocal services, and correspondence with primary human needs according to use values. Understanding the digital transformation of work from this point of view requires comprehending the differentiation and integration of these four dimensions.
We aimed to describe and compare the complications associated with different percutaneous radiologic gastrostomy (PRG) techniques.
A retrospective and prospective observational study was conducted. ...Patients who underwent a PRG between 1995-2020 were included.
A pigtail catheter was used until 2003, a balloon catheter without pexy was used between 2003-2009 and a balloon catheter with gastropexy was used between 2015-2021. For the comparison of proportions, X
tests or Fisher's test were used when necessary. Univariate analysis was performed to study the risk factors for PRG-associated complications.
= 330 (pigtail = 114, balloon-type without pexy = 28, balloon-type with pexy = 188). The most frequent indication was head and neck cancer. The number of patients with complications was 44 (38.5%), 11 (39.2%) and 54 (28,7%), respectively. There were seven (25%) cases of peritonitis in the balloon-type without-pexy group and 1 (0.5%) in the balloon-type with-pexy group, the latter being the only patient who died in the total number of patients (0.3%). Two (1%) patients of the balloon-type with-pexy group presented with gastrocolic fistula. The rest of the complications were minor.
The most frequent complications associated with the administration of enteral nutrition through PRG were minor and the implementation of the balloon-type technique with pexy has led to a decrease in them.
Aim
The aim of this paper is to describe the strategies used by nurses and midwives to cope with experiences of dealing with perinatal death and maintain their satisfaction at work.
Design
Systematic ...literature review, in accordance with the PRISMA Declaration.
Data Sources

Review Methods
The outcome of the review was the perceptions of nurses and midwives who have cared for people in a situation of perinatal loss.
Results
Thirteen studies were identified that evaluated the attitudes, experiences and needs of these healthcare professionals. The combined size of all samples was 2196 participants.
Conclusions
The negative effects on these professionals' satisfaction with their situation at work could be mitigated by covering their needs for knowledge, experience, and emotional and technical skills to deal with such events.
Impact
As potential protective factors against dissatisfaction in nurses and midwives during perinatal death experiences, we identified older age and experience in perinatal care and coping strategies based on communicating one's feelings to peers, empathetic listening to the families cared for, training and institutional support.

Camera pose estimation is vital in fields like robotics, medical imaging, and augmented reality. Fiducial markers, specifically ArUco and Apriltag, are preferred for their efficiency. However, their ...accuracy and viewing angle are limited when used as single markers. Custom fiducial objects have been developed to address these limitations by attaching markers to 3D objects, enhancing visibility from multiple viewpoints and improving precision. Existing methods mainly use square markers on non-square object faces, leading to inefficient space use. This paper introduces a novel approach for creating fiducial objects with custom-shaped markers that optimize face coverage, enhancing space utilization and marker detectability at greater distances. Furthermore, we present a technique for the precise configuration estimation of these objects using multiviewpoint images. We provide the research community with our code, tutorials, and an application to facilitate the building and calibration of these objects. Our empirical analysis assesses the effectiveness of various fiducial objects for pose estimation across different conditions, such as noise levels, blur, and scale variations. The results suggest that our customized markers significantly outperform traditional square markers, marking a positive advancement in fiducial marker-based pose estimation methods.
Sustained virological response (SVR) improves survival in post‐liver transplant (LT) recurrent hepatitis C. However, the impact of SVR on fibrosis regression is not well defined. In addition, the ...performance of noninvasive methods to evaluate the presence of fibrosis and portal hypertension (PH) post‐SVR has been scarcely evaluated. We aimed to investigate the degree of fibrosis regression (decrease ≥1 METAVIR stage) after‐SVR and its associated factors in recurrent hepatitis C, as well as the diagnostic capacity of noninvasive methods in the assessment of liver fibrosis and PH after viral clearance. We evaluated 112 hepatitis C virus–infected LT recipients who achieved SVR between 2001 and 2015. A liver biopsy was performed before treatment and 12 months post‐SVR. Hepatic venous pressure gradient (HVPG), liver stiffness measurement (LSM), and Enhanced Liver Fibrosis (ELF) score were also determined at the same time points. Sixty‐seven percent of the cohort presented fibrosis regression: 43% in recipients with cirrhosis and 72%‐85% in the remaining stages (P = 0.002). HVPG, LSM, and ELF significantly decreased post‐SVR. Liver function significantly improved, and survival was significantly better in patients achieving fibrosis regression. Baseline HVPG and LSM as well as decompensations before therapy were independent predictors of fibrosis regression. One year post‐SVR, LSM had a high diagnostic accuracy to discard the presence of advanced fibrosis (AF) and clinically significant PH (AUROC, 0.902 and 0.888). Conclusion: In conclusion, SVR post‐LT induces fibrosis regression in most patients, leading to significant clinical benefits. Pretreatment HVPG and LSM are significant determinants of the likelihood of fibrosis regression. Finally, LSM accurately predicts the presence of AF and PH 1 year after SVR and thus can be used to determine monitoring strategies. (Hepatology 2018;67:1683‐1694).
