ICT Use and Children’s Self-reported Life Satisfaction
Authors: Ayllón Sara , Brugarolas Pablo , Lado Samuel 
Published: February 2024

AbstractIn this chapter, we use the Children’s Worlds database to investigate how ICT affects children’s subjective well-being in Europe, and whether its use crowds out other activities, which could have an impact on how satisfied children are with their own lives. The survey queries 8-, 10-, and 12-year-old children regarding their daily routine and activities, use of time, and the extent to which they agree with several statements. The questionnaire also includes information on their social, economic, and demographic background and, most importantly for our research, their self-assessed well-being and thoughts on ICT usage. First, we find that a higher frequency of playing electronic games, using social media, and having Internet access and/or a mobile phone is positively associated with overall subjective well-being. Second, we find no evidence of any crowd-out effects—that is children who spend more time with digital devices do not report that they devote any less time to other activities. Finally, we document the fact that the use of digital technologies is positively related to satisfaction with the amount of free time they have and with their use of time. These results are generally not consistent with the main takeaways from causal studies which highlight the importance of further research on this area.
An MQDT Model for the Description of Time Resolved Pump Probe Experiments
Authors: Alarcón Miguel , Greene Chris H. 
Published: February 2024

AbstractA method based on multichannel quantum defect theory (MQDT) for the treatment of perturbative and time resolved photoionization in pump probe experiments is presented. Following an introduction to the theory, examples in two regimes of argon are presented. The theory successfully describes the energy distribution and the dependence on probe delay of the photoionization spectrum. We finalize with a discussion about angular distributions and possible further applications of the method.

AbstractWe induce valley-control in MoS2 with a polarization-shaped mid-infrared light field. The trefoil-shaped pump field is characterized by high harmonic spectroscopy and valley polarization is read our by a probe field via second harmonic generation.
Controlling the Time Evolution of Electron-Nuclei Entanglement for Steering Vibronic Coherences Dynamics Induced by Short 1–2 fs Optical Pulses
Authors: Blavier Martin , Gelfand Natalia , Levine R. D. , Remacle F. 
Published: February 2024

AbstractAtto pulses allow controlling the charge migration and the spatio-temporal beating of the electronic density on a purely electronic time scale by tailoring the parameters of the pump pulse to excite specific electronic coherences. As the nuclei begin to move, the electronic and nuclear motions are entangled and the engineered electronic coherences can be usefully exploited for steering the vibronic density to specific products through the network of non adiabatic interactions. Three recent examples for which we demonstrate such a control by fully quantum dynamical computations are discussed. Two diatomic molecules, LiH and N2 excited by a 2 fs deep UV pulse and the ultrafast structural Jahn-Teller rearrangement in CH4+. The entanglement between electronic and nuclear degrees of freedom arises from the optical excitation and from non adiabatic coupling induced by the nuclear motion. We provide insight of the coherence control mechanism by analyzing the time evolution of the entanglement using a singular valued decomposition (SVD) of the matricized wave function.

Published: February 2024

AbstractThe role of astrocyte networks in brain volume homeostasis and waste clearance has not received enough attention from the neuroscience community. However, recent research efforts indicate that glial cells are crucial for fluid flow through brain tissue, contributing to clearance and maintenance of brain volume. We examine the role of various glial cotransporters in the spatial and temporal changes of the intra- and extracellular volume fractions and fluid dynamics via computational modelling. The model is incorporated within the Kirchhoff-Nernst- Planck electrodiffusive framework and takes into account ionic electrodiffusion and fluid dynamics. Our research shows that all model configurations demonstrate similar fluid fluxes, except those involving HCO− 3 dynamics. The model configuration that included the NBC cotransporter was observed to have the greatest intracellular total volume-weighted fluid velocity of 16 μm/s.
Reconstruction of a Pancreatic Beta Cell Network From Heterogeneous Functional Measurements

Published: February 2024

AbstractIntercellular heterogeneity is fundamental to most biological tissues. For some cell types, heterogeneity is thought to be responsible for distinct cellular phenotypes and functional roles. In the pancreatic islet, subsets of phenotypically distinct beta cells (hub and leader cells) are thought to coordinate electrical activity of the beta cell network. This hypothesis has been addressed by experimental and computational approaches, but none have attempted to reconstruct functional specialization directly from measured heterogeneity. To evaluate if electrophysiologic heterogeneity alone can explain these specialized functional roles, we created a population of human beta cell models (via genetic algorithm optimization) recapitulating the heterogeneity in an extensive patch clamp dataset (1021 pancreatic cells). Then we applied the simplified Kirchhoff network (SKNM) formalism to simulate activity of that population in a connected beta cell network. We could not immediately observe cells with obvious hub or leader phenotypes within the heterogeneous network. However, with this study we built the basis for further ”ground-up” investigation of relationships between beta cell heterogeneity and human islet function. Moreover, our workflow may be translated to other tissues where large electrophysiologic data sets become available, and heterogeneity is thought to influence tissue function e.g. human atria.
Transnational Capital and Paper Production
Authors: Ehrich Martha Emilie 
Published: February 2024

AbstractThis chapter examines the progression of the Dutch paper industry during the post-Fordist phase, starting from 1980 onward. By highlighting both active and passive government interventions and economic restructuring within the context of the Dutch paper industry, the chapter challenges the notion that the state withdraws from regulatory involvement in the post-Fordist accumulation regime. State strategies, including the deregulation of market structures to facilitate widespread transnational ownership, neoliberal re-regulative initiatives involving closer collaboration between the public and private sectors for research and development, privatization of public sectors, active and passive financial support for industry demands, and the flexibilization of labor, all aimed at enhancing the international competitiveness of Dutch industries. The chapter clarifies the tensions that arise from the convergence of conflicting class fraction interests, with a focus on industry sustainability, emerging forms of labor precarity, and heightened competition.

ZusammenfassungDas deutsche Bildungssystem, so wie es sich zu Beginn des 21. Jahrhunderts dem Betrachter darstellt, ist das Ergebnis einer Entwicklung, die sich im deutschsprachigen Raum insbesondere während der letzten dreihundert Jahre – vom 18. Jahrhundert bis in die Gegenwart hinein – vollzogen hat. Seine Darstellung bedarf daher, soll es richtig verstanden werden, einer historischen Rückerinnerung. Mit der historischen Perspektive wird eine Folie geboten, ohne die Besonderheiten dieses Bildungssystems über weite Strecken unverstanden bleiben müssen.

S-duality in the Cardy-like limit of the superconformal index
Authors: Amariti Antonio , Zanetti Andrea 
Published: February 2024

Abstract
We evaluate the superconformal index of 4d $$ \mathcal{N} $$
N
= 4 SYM with gauge algebra so(2Nc + 1) in the Cardy-like limit. We then study the relation with the results obtained for the S-dual usp(2Nc), discussing the fate of S-duality in different regions of charges. We find that S-duality is preserved thanks to a non-trivial integral identity that relates the three sphere partition functions of pure 3d Chern-Simons gauge theories.
Anomaly detection in the presence of irrelevant features
Authors: Freytsis Marat , Perelstein Maxim , San Yik Chuen 
Published: February 2024

Abstract
Experiments at particle colliders are the primary source of insight into physics at microscopic scales. Searches at these facilities often rely on optimization of analyses targeting specific models of new physics. Increasingly, however, data-driven model-agnostic approaches based on machine learning are also being explored. A major challenge is that such methods can be highly sensitive to the presence of many irrelevant features in the data. This paper presents Boosted Decision Tree (BDT)-based techniques to improve anomaly detection in the presence of many irrelevant features. First, a BDT classifier is shown to be more robust than neural networks for the Classification Without Labels approach to finding resonant excesses assuming independence of resonant and non-resonant observables. Next, a tree-based probability density estimator using copula transformations demonstrates significant stability and improved performance over normalizing flows as irrelevant features are added. The results make a compelling case for further development of tree-based algorithms for more robust resonant anomaly detection in high energy physics.
Transitional circulation patterns from full ice cover to ice-off in a seasonally ice-covered lake
Authors: Hughes Katie Stagl , Forrest Alexander L. , Cortés Alicia , Bombardelli Fabián A. 
Published: February 2024

AbstractThere is consensus that under-ice circulation presents multiple phases through the winter, and that different mechanisms dominate each period. In this work, measurements of temperature, water velocity, conductivity, and dissolved oxygen from Lake Massawippi, Quebec, Canada, obtained during the ice-covered season in 2019, were used to characterize the time scales of different winter regimes and transitions among dominating circulation mechanisms. Lake circulation during this period began with a single-cell convection induced by sediment flux pulses in early winter. The single-cell convection decayed into a brief quiescent period. Radiatively driven convection then formed a convectively mixed layer in late winter. The defined mixed layer and temperature structure provided the necessary conditions for the formation of a potential rotational feature, which briefly formed immediately prior to ice break-up. Ice break-up led to complex hydrodynamics that persisted for nearly 28 days following full ice-off. Dissolved oxygen was directly correlated with the varying circulation features throughout the field campaign. This work provides a quantitative measure to delineate the transitions between under-ice regimes and provides novel insights into the subsequent circulation during and after ice break-up.

AbstractThe objective of this study is to compare and contrast the quality statements and quality indicators across clinical care standards for low back pain. Searches were performed in Medline, guideline databases, and Google searches to identify clinical care standards for the management of low back pain targeting a multidisciplinary audience. Two independent reviewers reviewed the search results and extracted relevant information from the clinical care standards. We compared the quality statements and indicators of the clinical care standards to identify the consistent messages and the discrepancies between them. Three national clinical care standards from Australia, Canada, and the United Kingdom were included. They provided from 6 to 8 quality statements and from 12 to 18 quality indicators. The three standards provide consistent recommendations in the quality statements related to imaging, and patient education/advice and self-management. In addition, the Canadian and Australian standards also provide consistent recommendations regarding comprehensive assessment, psychological support, and review and patient referral. However, the three clinical care standards differ in the statements related to psychological assessment, opioid analgesics, non-opioid analgesics, and non-pharmacological therapies. The three national clinical care standards provide consistent recommendations on imaging and patient education/advice, self-management of the condition, and two standards (Canadian and Australian) agree on recommendations regarding comprehensive assessment, psychological support, and review and patient referral. The standards differ in the quality statements related to psychological assessment, opioid prescription, non-opioid analgesics, and non-pharmacological therapies.
Generating a full spherical view by modeling the relation between two fisheye images

Published: February 2024

AbstractFull spherical views provide advantages in many applications that use visual information. Dual back-to-back fisheye cameras are receiving much attention to obtain this type of view. However, obtaining a high-quality full spherical view is very challenging. In this paper, we propose a correction step that models the relation between the pixels of the pair of fisheye images in polar coordinates. This correction is implemented during the mapping from the unit sphere to the fisheye image using the equidistant fisheye projection. The objective is that the projections of the same point in the pair of images have the same position on the unit sphere after the correction. In this way, they will also have the same position on the equirectangular coordinate system. Consequently, the discontinuity between the spherical views for blending is minimized. Throughout the manuscript, we show that the angular polar coordinates of the same scene point in the fisheye images are related by a sine function and the radial distance coordinates by a linear function. Also, we propose employing a polynomial as a geometric transformation between the pair of spherical views during the image alignment since the relationship between the matching points of pairs of spherical views is not linear, especially in the top/bottom regions. Quantitative evaluations demonstrate that using the correction step improves the quality of the full spherical view, i.e. IQ MS-SSIM, up to 7%. Similarly, using a polynomial improves the IQ MS-SSIM up to 6.29% with respect to using an affine matrix.
A closer look to the timing of orchidopexy in undescended testes and adherence to the AWMF-guideline
Authors: Von Cube C. , Schmidt A. , Krönninger M. , Hrivatakis G. , Astfalk W. , Fuchs J. , Ellerkamp V. 
Published: February 2024

Abstract
Background
To lower the risk of testicular malignancies and subfertility, international guidelines recommend orchidopexy for undescended testis (UDT) before the age of 12–18 months. Previous studies reported low rates of 5–15% of timely surgery. Most of these studies are based on DRG and OPS code-based data from healthcare system institutions that do not distinguish between congenital and acquired UDT.

Methods
In a retrospective study data of all boys who underwent orchidopexy in a university hospital and two outpatient surgical departments from 2009 to 2022 were analyzed. The data differentiates congenital from acquired UDT.

Results
Out of 2694 patients, 1843 (68.4%) had congenital and 851 (31.6%) had acquired UDT. In 24.9% of congenital cases surgery was performed before the age of 12 months. The median age at surgery for congenital UDT was 16 months (range 7–202). Over the years there was an increased rate of boys operated on before the age of 2 (40% in 2009, 60% in 2022). The median age fluctuated over the years between 21 and 11 months without a trend to younger ages.. The covid pandemic did not lead to an increase of the median age at surgery. The median time between referral and surgery was 46 days (range 1–1836). Reasons for surgery after 12 months of age were a delayed referral to pediatric surgeries (51.2%), followed by relevant comorbidities (28.2%).

Conclusion
Compared to recent literature, out data show that a closer look at details enables a more realistic approach. Still, there is no trend towards the recommended age for surgical treatment observable, but the rate of timely operated boys with congenital UDT is significantly higher than stated in literature.
Different effects of inspiratory duration and expiratory duration on heart rate deceleration capacity and heart rate asymmetry
Authors: Wang Yong-Ping , Kuo Terry B. J. , Wang Guo-Zhi , Yang Cheryl C. H. 
Published: February 2024

Abstract
Purpose
Low values of heart rate deceleration capacity (DC) and heart rate asymmetry (HRA) are associated with cardiovascular risks. Slow respiration has been proven to enhance the magnitudes of these indexes, but individual inspiratory (TI) and expiratory (TE) durations were not controlled in most studies. This study aims to examine whether the effects of TI and TE on these indexes would be the same and, if not, how to adjust TI and TE to maximize the effect of slow respiration.

Methods
We evaluated 14 seated healthy young adults who randomly controlled their breathing to nine combinations of TI and TE, each chosen respectively from 2, 4, and 6 s. A 5-min R-R interval time series was obtained from each study period for further analysis.

Results
The magnitude of DC increased when TI or TE increased, while that of acceleration capacity (AC) remained almost unchanged by TI. We further defined a new index as 100 × DC2/(DC2 + AC2) and found it to be correlated with conventional Guzik’s (r = 0.94) and Porta's (r = 0.99) indexes of HRA during different combinations of TI and TE. Increasing TI and increasing TE both enhanced the magnitudes of HRA indexes, with TI taking effect when ≤ 4 s, and TE taking effect when > 4 s. DC and HRA indexes were maximized with a TI of 4 s and a TE of 6 s.

Conclusion
We suggest that a TI of 3–4 s with a TE of 7–6 s is an appropriate standard for slow respiration.
Short-term results of laparoscopic anti-reflux surgery with the RefluxStop device in patients with gastro-esophageal reflux disease and ineffective esophageal motility

Published: February 2024

Abstract
Purpose
In gastro-esophageal reflux disease (GERD) requiring surgical treatment, concomitant ineffective esophageal motility (IEM) is a decisive factor in surgical planning, due to concern regarding dysphagia. Anti-reflux surgery with the RefluxStop device is a promising technique. We assessed initial feasibility and clinical outcomes of RefluxStop surgery in patients with GERD and IEM.

Methods
Retrospective analysis of patients with GERD, hiatal hernia (HH), and IEM, who underwent surgery with RefluxStop at our institution and achieved 12-month follow-up. Technique feasibility was assessed, in addition to symptom resolution (GERD-HRQL questionnaire), adverse events, HH recurrence, dysphagia, and patient satisfaction. Placement of the device was confirmed by video fluoroscopy on postoperative day 1, and at 3 and 12 months.

Results
Between June 2020 and November 2022, 20 patients with IEM underwent surgery with RefluxStop and completed 12-month follow-up. All patients reported typical symptoms of GERD, and 12 had preoperative dysphagia. The median HH length was 4.5 cm (IQR, 3.75–5). The median operating time was 59.5 min (IQR, 50.25–64) with no implant-related intra- or postoperative complications. No HH recurrence was observed. One patient reported persistent left-sided thoracic pain at 11 months post-surgery, which required diagnostic laparoscopy and adhesiolysis. Three patients reported severe postoperative dysphagia: balloon dilatation was performed towards resolution. The mean GERD-HRQL scores improved (from 40.7 at baseline to 4.8 at 3 months and 5.7 at 12 months (p <0.001)).

Conclusion
RefluxStop surgery was feasible and offered effective treatment for this group of patients with GERD and IEM. All patients had complete resolution or significant improvement of GERD symptoms, and 90% of them were satisfied with their quality of life 1 year after surgery.
