Current state-of-the art review of footwear-ground friction
Authors: Rebenda David , Sáha Tomáš 
Published: August 2024

AbstractThe most important role of footwear is to ensure safe, functional walking, and foot protection. For the proper functionality of not only the work shoes, the anti-slip behavior of the shoe under various conditions and environments plays an important role in the prevention of slips, trips, falls, and consequent injuries. This article is intended to review the current understanding of the frictional mechanisms between shoe outsoles and various counterfaces that impact the evaluation of outsole slipperiness. Current research focuses on the mechanisms driving outsole friction on different ground surfaces or the definition and description of parameters that influence outsole friction. Subsequently, the review discusses the effect of various surface contaminants on footwear friction. Lastly, challenges and outlooks in the field of footwear outsoles are briefly mentioned.
Influence of water evaporation on elastohydrodynamic lubrication with water-containing polyalkylene glycols

Published: August 2024

AbstractThe reduction of frictional power losses in power transmitting gears takes a crucial role in the design of energy- and resource-efficient drivetrains. Water-containing lubricants like glycerol and polyalkylene glycols have shown great potential in achieving friction within the superlubricity regime with coefficients of friction lower than 0.01 under elastohydrodynamic lubrication. Additionally, a bio-based production of the base stocks can lead to the development of green lubricants. However, one challenge associated with the application of water-containing lubricants to gearboxes is the evaporation of water and its impact on the lubricant properties. In this study, the influence of water evaporation on elastohydrodynamic friction and film thickness was investigated for three water-containing polyalkylene glycols. Two nominal water contents of 20 wt% and 40 wt% and two viscosities were considered. The results show that the friction increases continuously with higher evaporated water content, while the overall friction level remains low in nearly water-free states. A similar trend is observed for film thickness, where the strong increase in viscosity results in a notable increase in film thickness. Nevertheless, the sensitivity of friction and film thickness to water evaporation is low for small amounts of evaporated water. This allows generous thresholds for permissible variations in water content.
Revisiting Teacher-Family Partnerships: A Critical Policy Analysis of Pacific Education Policy 2009–2030

Published: August 2024

AbstractStrong teacher-family partnerships are vital for children’s educational success. Educational policies influence how teachers perceive and engage in these significant relationships. Critical policy analysis focuses on the language, and underlying meanings and beliefs that reify certain understandings and positions in policy. We trace changes in positioning teacher-family relationships in three versions of policy, illustrating the prioritisation of dominant non-Pacific cultures over Pacific languages, cultures, and identities. We propose embracing Samoan concepts like va tapuia (sacred relationships) and teu le va (looking after relationships) as ethical imperatives for teachers to value and nurture respectful relationships with Pacific peoples. We recommend an open-minded approach, including strengths-based visits to Pacific children’s family homes. Drawing from successful projects in Aotearoa New Zealand, we urge policymakers and educational leaders to ensure teachers have the time and resources for the dialogue and reflective activities before and following visits that are needed to transform practice.
Focused, Flourishing, but Not in Flow: Achievement Strivers’ Experiences of Competence, Flow, and Well-Being During Personally Expressive Activities
Authors: Hill Taylor G. , Loock Johanna V. , Mackinnon Sean P. 
Published: August 2024

AbstractOne effective route to increasing well-being is through the pursuit of activities which suit a person’s personality strengths (i.e., person-activity fit). People who strive for achievement tend to organize their behaviors in ways that promote goal attainment and well-being. We tested the hypothesized process that achievement striving would lead to increased well-being over time through feelings of competence and flow. A secondary aim was to describe the types of personally valued activities and whether activity type facilitates competence and flow. Undergraduate students (N = 346 at Time 1; N = 244 at Time 2) completed an online survey measuring personality, personally expressive activities, basic psychological need satisfaction, flow, and well-being at two timepoints ~ 4 months apart. Two coders thematically coded activities into seven types (e.g., reading and writing, hobbies). We used cross-sectional and longitudinal serial mediation models to test our hypothesis with eudaimonic (life worth) and hedonic (life satisfaction) well-being, controlling for sample characteristics (recruitment source and term). Achievement striving was positively correlated to competence and well-being, but the indirect effects did not show that well-being is boosted by feeling competent and in flow during in personally expressive activities, cross-sectionally or longitudinally. Perceived competence was comparable across activity types, although flow was highest in reading and writing activities. While achievement strivers tended to feel happy and competent at personally expressive activities, the mechanistic pathway to well-being is not yet clear. Future studies might recruit larger sample sizes and utilize smaller time lags (e.g., ecological momentary assessment).
Two Approaches of ‘Proactive Consultation’: Towards Well-Functioning Clinical Ethics Consultation
Authors: Kogetsu Atsushi , Koimizu Jungen 
Published: August 2024

Abstract
In recent years, the global need for clinical ethics consultation services (CECS) has increased to address ethical challenges, dilemmas, and moral distress in clinical environments. In Japan, many hospitals have introduced CECS over the past decade, but few such services work effectively because of the small number of consultations. To address this, we propose two proactive ethics consultation methods: inter-professional ethics rounds and patient note reviews. This paper provides a detailed explanation of these methods, complete with scenarios based on actual cases. These methods can make CECS ‘well-functioning’ by shifting the starting points of consultation from consultees to CECS providers. We then examine the impact and value of proactive ethics consultation as well as four critical factors for its success including attitude, positioning, and competency of proactive consultation teams. We believe our suggestions will provide valuable insights for future clinical ethics consultations and stimulate academic debate about what constitutes a ‘well-functioning’ CECS.

Published: August 2024

AbstractThe aquatic plant Nymphaea, a model genus of the early flowering plant lineage Nymphaeales and family Nymphaeaceae, has been extensively studied. However, the availability of chloroplast genome data for this genus is incomplete, and phylogenetic relationships within the order Nymphaeales remain controversial. In this study, 12 chloroplast genomes of Nymphaea were assembled and analyzed for the first time. These genomes were 158,290–160,042 bp in size and contained 113 non-repeat genes, including 79 protein-coding genes, 30 tRNA genes, and four rRNA genes. We also report on codon usage, RNA editing sites, microsatellite structures, and new repetitive sequences in this genus. Comparative genomics revealed that expansion and contraction of IR regions can lead to changes in the gene numbers. Additionally, it was observed that the highly variable regions of the chloroplast genome were mainly located in intergenic regions. Furthermore, the phylogenetic tree showed the order Nymphaeales was divided into three families, and the genus Nymphaea can be divided into five (or three) subgenera, with the subgenus Nymphaea being the oldest. The divergence times of nymphaealean taxa were analyzed, with origins of the order Nymphaeales and family Nymphaeaceae being about 194 and 131 million years, respectively. The results of the phylogenetic analysis and estimated divergence times will be useful for future evolutionary studies of basal angiosperm lineages.
Prognosticating accelerated deterioration in skeletally mature adolescent idiopathic scoliosis curves of 40–50° using uniplanar radiographic measures of axial rotation

Published: August 2024

Abstract
Purpose
The management of adolescent idiopathic scoliosis (AIS) curves between 40 and 50° is controversial. Here, we investigated the prognostic significance of simple radiographic rotational parameters to identify curves of this magnitude with accelerated deterioration following skeletal maturity.

Methods
Seventy-three patients were identified with AIS and Cobb angles of the major curve between 40 and 50° at skeletal maturity. We defined fast progressive curves as those increasing by ≥ 2° per year after skeletal maturity. From the apical vertebra of the major curve upon presentation and skeletal maturity, we determined the modified Nash–Moe index (×100), and from thoracic major curves, the Rib Index. T tests were performed to compare fast-progressive curves with those that deteriorated by < 2° per year. Receiver operator characteristic (ROC) curves were plotted to establish optimal cutoffs, sensitivity, and specificity measures for rotational parameters.

Results
The average duration of follow-up post was 11.8 ± 7.3 years. Thirteen out of seventy-three patients were fast progressors. The modified Nash–Moe index was similar between groups at presentation (p = 0.477) but significantly higher in fast progressors than non-fast progressors at maturity for major thoracic curves (25.40 ± 6.60 vs. 19.20 ± 4.40, p < 0.001). Rib Index values were also higher among fast progressors at skeletal maturity (2.50 ± 0.90 vs. 1.80 ± 0.60, p = 0.026). An ROC curve for a modified Nash–Moe index of 0.235 for thoracic curves achieved an area under the curve (AUC) of 0.76 for discriminating fast progressors. A threshold of 1.915 for Rib Index at maturity achieved an AUC of 0.72 for discriminating fast progressors. In combining both rotational parameters, an AUC of 0.81 was achieved.

Conclusion
These simple rotational parameters may be useful to predict fast progression in 40–50° AIS curves following skeletal maturity indicated for early fusion, but further validation upon larger cohorts and non-thoracic major curves is required.
Rethinking Consumer Empowerment: New Directions for Sustainable Food Law in an Era of EU Discontent
Authors: Delhomme Vincent 
Published: August 2024

AbstractEU food law is built on two paradigms – food safety and consumer choice. Consumers should have access to any food they like, provided that it is safe for consumption and that consumers are made aware of the products’ characteristics through adequate information. Growing emphasis on sustainability has not challenged these foundations. On the contrary, the law is intended as a tool to further empower consumers to make a healthy and environmentally responsible choice. However, it will be argued that this information centric approach is no longer a tenable position. The regulatory solutions characteristic of the consumer empowerment logic are of limited effectiveness and do not challenge the biggest obstacles to the sustainable transition of food systems – the commodification of food and the lack of regulation of the food environment. This contribution sketches out some far-reaching yet realistic food law reforms to genuinely address sustainability issues. Mindful of the special status of food and the growing discontent towards the EU and the green transition, this contribution also argues for some changes in the making and design of EU food law, leading towards greater involvement of citizens and local communities, and, ultimately, for truer empowerment of individuals.
Quality of legislation and compliance: a natural language processing approach
Authors: Osnabrügge Moritz , Vannoni Matia 
Published: August 2024

Abstract
Several disciplines, such as economics, law, and political science, emphasize the importance of legislative quality, namely well-written legislation. Low-quality legislation cannot be easily implemented because the texts create interpretation problems. To measure the quality of legal texts, we use information from the syntactic and lexical features of their language and apply these measures to a dataset of European Union legislation that contains detailed information on its transposition and decision-making process. We find that syntactic complexity and vagueness are negatively related to member states’ compliance with legislation. The finding on vagueness is robust to controlling for member states’ preferences, administrative resources, length of texts, and discretion. However, the results for syntactic complexity are less robust.
Resilience of DNA chains to molecular fracture after PCR heating cycles and implications on PCR reliability
Authors: Serpieri Roberto , Franchi Fabio 
Published: August 2024

Abstract
Soon after its introduction in 1987, polymerase chain reaction (PCR) has become a technique widely employed in diagnostic medical devices and forensic science with the intention of amplifying genetic information. PCR prescribes that each of its cycles must include a heating subprocess at 95 °C or more (denominated DNA denaturation and provided for allowing a claimed orderly separation of the two complementary nucleotides strands), which can produce significant damage to DNA, caused by high-speed collisions with surrounding molecules. Since such disruption should be prevented in order to reliably employ PCR, a study of the mechanics of such loss of structural integrity is herein presented, preceded by a review of the fundamental literature which has elucidated the effects of molecular agitation on DNA fragmentation. The main conclusion of this retrospective survey is that the body of examined theoretical and experimental evidence consistently and redundantly confirms scarce resilience and significant loss of structural integrity when DNA is heated at temperatures above 90 °C, even for 1 minute. Such conclusion contradicts the claimed paradigm of PCR fidelity and raises the concern that, at least for long sequences, if PCR can amplify some information, such amplified information may be unreliable for diagnostic or forensic applications, since it originates from sequences of nucleotides subjected to random fragmentation and reaggregation. Such a low-reliability scenario should be preventively considered in the various fields where DNA amplification methodologies are employed which provide for high-temperature heating under conditions equal to or similar to those prescribed by the PCR protocols reviewed in this study.

AbstractExpendable Bathythermographs (XBTs) are oceanographic instruments that fall through the ocean's water column and measure ocean temperature with depth. In many instances, however, XBTs continue to record temperature after they impact the seabed. Here we show evidence that XBTs produce unique temperature responses when they impact the seabed that depend directly on seabed physical properties. Specifically, standard‐use XBTs (e.g., T‐4s and T‐5s), when deployed above a mud‐rich seabed, require significant time (tens of minutes) to equilibrate to steady‐state seafloor temperatures after seabed impact. In contrast, XBTs deployed above sand‐rich sediments equilibrate to seabed temperatures rapidly (<5 min) after seafloor impact. One explanation for this difference in temperature response is that XBTs deployed above mud‐rich sediment penetrate into low permeability marine muds that jacket the XBT, where diffusive heat flow dominates. Both observations and numerical modeling results support the hypothesis that XBTs impacting muddy seafloors exhibit slow, diffusion‐dominated heat flow, while XBTs impacting harder, sand‐rich seabed sites exhibit rapid seafloor temperature equilibration, consistent with advection‐driven heat flow and little if any XBT seabed penetration. Given that >644k XBT measurements exist publicly (via the National Oceanographic and Atmospheric Administration website), and >74,000 XBTs record temperatures post seabed impact, we suggest that XBT data represents a large, low‐cost, and currently untapped data set for characterizing seabed physical properties globally.
Impacts of Topography‐Based Subgrid Scheme and Downscaling of Atmospheric Forcing on Modeling Land Surface Processes in the Conterminous US

Published: August 2024

AbstractThe effects of small‐scale topography‐induced land surface heterogeneity are not well represented in current Earth System Models (ESMs). In this study, a new topography‐based subgrid structure referred to as topographic units (TGU) designed to better capture subgrid topographic effects, and methods to downscale atmospheric forcing to the land TGUs have been implemented in the Energy Exascale Earth System Model (E3SM) Land Model (ELM). Effects of the subgrid scheme and downscaling methods on ELM simulated land surface processes are evaluated over the conterminous United States (CONUS). For this purpose, ELM simulations are performed using two configurations without (NoD ELM) and with (D ELM) downscaling, both using TGUs derived for the 0.5‐degree grids and the same land surface parameters. Simulations using the two ELM configurations are compared over the CONUS domain, regional levels, and at observational sites (e.g., SNOTEL). The CONUS‐level results suggest that D ELM simulates more snowfall and snow water equivalent (SWE), higher runoff, and less ET during spring and summer. Regional‐level results suggest more pronounced impacts of downscaling over regions dominated by higher elevation TGUs and regions with maximum precipitation occurring during cool seasons. Results at the SNOTEL sites suggest that D ELM has superior capability of reproducing the observed SWE at 83% of the sites, with more pronounced performance over topographically heterogeneous TGUs with their maximum precipitation occurring during cool seasons. The results highlight the importance of improving representation of small‐scale surface heterogeneity in ESMs and motivate future research to understand their effects on land‐atmosphere interactions, streamflow, and water resources management over mountainous regions.
Historical Trends in Cold‐Season Mid‐Latitude Cyclones in the Great Lakes Region
Authors: Hutson Abby , Fujisaki‐Manome Ayumi , Glassman Ryan 
Published: August 2024

AbstractThe Great Lakes Region (GLR) of North America is at the intersection of multiple extratropical cyclone (ETC) tracks, and the region's cold‐season climate is heavily influenced by the large temperature gradients and intense precipitation associated with these cyclones. The goal of this study is to understand how ETCs are changing within a warming climate. Historical GLR cyclone characteristics from 1959 to 2021 are examined using a storm tracking algorithm and the ERA‐5 atmospheric reanalysis. Of the 886 cyclones identified, half are the large long‐track cyclones that are typically included in ETC studies, and half are smaller short‐track cyclones that, while not always considered in ETC studies, still have an important impact on the GLR with significant precipitation trends. While all cyclones exhibit strong interannual variability, storm trajectories appear to be migrating northward and, most notably, the cyclones are becoming warmer and wetter at a rate faster than the background climate.
Spatial Distribution of Tremor Episodes From Long‐Term Monitoring in the Northern Cascadia Subduction Zone

Published: August 2024

AbstractLarge bursts of non‐volcanic tremor (“major” tremor episodes) correlated with geodetic deformation recur regularly in the Cascadia subduction zone and are often called episodic tremor and slip (ETS). Minor episodes of tremor between ETS are ubiquitous but have been understudied. This paper assesses time‐invariant characteristics of tremor episodes of all sizes within northern Cascadia. We derive a catalog of tremor episodes ranging in size from 10 to >13,000 tremor events using the results of 17 years of tremor monitoring. Minor episodes represent ∼96% of all 896 tremor episodes and their occurrence varies on 10‐km scales. Using estimates for the depth of the forearc Moho and subducting slab, we observe an association between the location of the forearc mantle corner (FMC) and tremor occurrence that leads to along‐dip modality. Bimodality, present in southern Washington and Vancouver Island, represents the segmentation of major and minor episodes up‐dip and down‐dip of the FMC, respectively. Unimodality, present in Puget Sound, results when the FMC is located near the down‐dip edge of the ETS zone and no segmentation occurs. We also use our extensive tremor episode catalog alongside three‐dimensional regional tomographic velocity models to reassess the relationship between tremor activity and low Vp/Vs signatures in the forearc. We do not find a correlation between tremor episode recurrence intervals and Vp/Vs, contrary to some previous work, suggesting that controls on silica precipitation in the forearc crust are not dominant controls of tremor episode recurrence, or that the association is not widely observable.
