Respiratory Exposure to Highly Fluorinated Chemicals via Application of Ski Wax and Related Health Effects
Authors: Crawford Kathryn A. , Hartmann Nicola 
Published: January 2024

Abstract
Purpose
Waxes containing per- and polyfluoroalkyl substances (PFAS) are applied to the base of skis and snowboards (“skis”) to reduce friction with the snow surface and improve glide. PFAS exposure can adversely impact cardiometabolic, thyroid, liver, kidney, reproductive, and immune health and are associated with increased risk of certain cancers. In the present review, we summarize the state of the science on PFAS exposure from fluorinated ski wax use, including acute respiratory health effects and PFAS concentrations in biological and environmental media collected from ski waxing settings.

Recent Findings
Perfluoroalkyl carboxylic acid (PFCA) concentrations in serum and air collected from professional wax technicians and the rooms where waxes are applied are among the highest of any occupation investigated to date, including the fluorochemical industry. High airborne concentrations of fluorotelomer alcohols contribute to high body burdens of certain PFCAs among ski waxers.

Summary
Fluorinated ski waxes are a significant source of PFAS exposure for people waxing skis and/or spending time in areas where waxing occurs. We highlight recommendations for future research, policy, and technologies needed to address PFAS exposures from fluorinated wax use.
Between the dog and the wolf: an interpretative phenomenological analysis of bicultural, sexual minority people’s lived experiences
Authors: Miller Emelie Louise , Zakrisson Ingrid 
Published: January 2024

AbstractPrevious research has established that people with multiple-minority identities frequently wrestle with psychosocial dilemmas in ingroup and outgroup settings, which can impair health and impede a positive belonging. The present study explores the phenomenon of psychosocial implications found in the intersection of sexuality and ethnicity from the perspective of bicultural, sexual minority individuals in Sweden, a multiple-minority group that thus far has not received scientific consideration. In-depth interviews were conducted with eight non-heterosexual, second-generation immigrants in Sweden. Data was analyzed through a collaborative interpretative phenomenological analysis. Two overarching group experiential themes (GETs) were created: “A puzzle of identity struggles” and “Sources of empowerment.” The GETs detail experiences of bullying, misidentification, parental shortcomings, gender issues, and severe mental health challenges, as well as strengthening factors in the participants’ lived experiences, including pride in heritage, creative coping strategies and purpose in life. The lines between general stressors and minority-specific stressors were blurred, which problematizes simplified understandings of multiple-minorities. The authors advocate for advances in multiple-minority knowledge among professionals within the educational and mental health systems, to facilitate preventive and interventive work that could improve life conditions and sense of belonging among non-heterosexual, ethnic minorities.
Contract noncompliance in agricultural conservation programs: Panel evidence from Louisiana, USA
Authors: Pathak Santosh , Wang Hua , Adusumilli Naveen C. 
Published: January 2024

AbstractCost-share contracts, offered through working lands programs, are instrumental in addressing environmental externalities from agriculture and generating ecosystem services. However, the persistent trend of noncompliance with cost-share contractual terms has become a problem for funding agencies and policymakers. This paper aims to study noncompliance issues within the US working lands programs using historical county-level panel data (1997–2019) from Louisiana. The results show that noncompliance is attributed more to cancellations than terminations due to flexible provisions within the cancellation option. The significant incentive effect of payment obligations reveals that revisiting payment rates could reduce contract noncompliance and mitigate moral hazard.
Demystifying Autonomy: Tracing the International Law Origins of the EU Principle of Autonomy
Authors: Konstantinidis Mark 
Published: January 2024

AbstractCJEU case law has long emphasized the autonomy of the EU legal order, recently triggering the foreclosure of intra-EU investment arbitration. Though academic discourse has treated this as a European peculiarity, autonomy is not unfamiliar to international law as an inherent attribute of all international organizations (IOs). This Article traces how the CJEU employed this as the basis for the development of a legal principle of significant constitutional role in safeguarding the EU’s jurisdictional integrity. First, It considers the EU conception of autonomy on the basis of two identified dimensions of IOs’ autonomy under international law. Political autonomy characterizes the scope of an IO’s powers and its independent legal personality. Institutional autonomy denotes its (im)permeability to external norms. Second, the Article examines autonomy’s different normative status under international and EU law as a legal notion and a constitutional principle, respectively. Rather than viewing the latter as an EU invention, it amounts to a Pygmalian judicial creation—the CJEU drew inspiration from a notion of international law and adapted it within the Union framework. The Article justifies these adaptations by reference to international law in light of the EU’s institutional-judicial architecture and the intertwining of autonomy with, inter alia, Article 2 TEU values.

Abstract
This study aimed to complement the previous studies conducted within a short period of time by examining the long-term trends in depression levels of older adults through a longitudinal study that includes the period following the onset of COVID-19. For analysis, this study used the data from the 12th (2017) through 16th (2021) Korea Welfare Panel Study, and 2,716 data of older adults 65 years and older were included. Variables included gender, age, equalized annual income (USD $), education background, residential area, living alone and disability status. As a result, two types of changes in depression were identified: the ‘rapidly rising’ type and the ‘steadily increasing’. We found that the lower the equalized annual income, women, the lower the education, living in urban and living alone showed a higher likelihood of belonging to the ‘rapidly rising’ type. The result suggests that those at risk of depression are at much higher risk during and after the COVID-19 pandemic. It is also necessary to provide timely and effective guidelines to prevent depression in older adults when implementing policies in response to an outbreak of infectious diseases, such as COVID-19.
In vitro assessment of isopropanol leakage from antiseptic barrier caps into commonly used needleless connectors

Published: January 2024

AbstractBackground:Needleless connectors (NCs) can be disinfected using antiseptic barrier caps (ABCs) to reduce the risk of catheter-related bloodstream infections. However, recent evidence suggests that isopropanol can leak from the ABC into the NC, posing concern about their safe use. We sought to determine in vitro which ABC and NC parameters influence the leakage of isopropanol through the infusion circuit.Methods:We assessed 13 NCs and 4 ABCs available in the European market. In vitro circuits consisting of an isopropanol cap, a NC, and an 11-cm catheter line were created. The circuits were left in place for 1 to 7 days at room temperature to assess the kinetics of isopropanol leakage. Isopropanol content in ABC and in circuit flushing solutions (5 mL NaCl 0.9%) after exposure to the cap were measured using gas chromatography with a flame ionization detector.Results:The leakage of isopropanol from the cap to the NC was dependent on the NC, but not the cap. The NC mechanism did not predict the leakage of isopropanol. The Q-Syte NC exhibited the most isopropanol leakage (7.01±1.03 mg and 28.32±2.62 mg at 24 hours and 7 days, respectively), whereas the Caresite NC had the lowest isopropanol leakage at 7 days (1.69±0.01 mg).Conclusion:The use of isopropanol ABCs can cause isopropanol leakage into the catheter circuit according to NC parameters. Caution should be exercised when using these devices, especially in the pediatric and neonatal population.
The effect of diet restriction on raw milk stability: a meta-analytical approach

Published: January 2024

AbstractThis research communication was designed to evaluate the effects of different levels of diet restriction on the composition and ethanol stability (MES) of raw bovine milk. This research was carried out using three electronic databases: Scopus, Pubmed and Web of Science. The main inclusion criteria were: (i) original research, (ii) use of alcohol (ethanol) test as a method to assess milk stability, (iii) measure different levels of feed restriction and (iv) allow access to the raw data of articles. Of the nine publications that addressed the subject filtered by the systematic review, seven fitted the selection criteria and were selected to perform the meta-analysis. Feed restriction (reduction of 20, 30, 40 and 50% of the dietary dry matter offered) decreased (P < 0.01) milk yield (−18%), ethanol stability (−5%), acidity (−4%), protein (−3%) and lactose (−2%) concentrations, but did not affect the values of pH, density, fat and total solids concentrations, nor somatic cell count. The correlation between milk yield and MES was low but positive and numerically higher in the control group compared with the restriction group. The milk of cows fed the control diet presented greater ethanol stability (76.5%) compared with milk of cows fed the restrictive diet (72.8%). This decrease by up to 4 percentage units due to restriction levels ranging from 20 to 50% of diet intake may cause limitations in milk processing at the dairy industry, increasing milk rejection.
Gastrointestinal helminths of the Australasian harrier (Circus approximans Peale, 1848) in New Zealand, and description of a new species of nematode, Procyrnea fraseri n. sp. (Habronematidae)
Authors: Presswell Bronwen , Bennett Jerusha 
Published: January 2024

Abstract
The Australasian harrier Circus approximans, a native of Australia, New Zealand and the South Pacific, is an opportunistic hunter of small prey, although a large part of its diet consists of carrion, mainly from roadkill. Besides a record of a single, unnamed species of capillariid nematode there have been no investigations into the parasites of Australasian harriers in New Zealand. In this study, a helminthological survey of sixty-five deceased harriers from southern New Zealand uncovered a gastrointestinal helminth fauna consisting of six parasite species. Porrocaecum circinum (Nematoda) was previously described only from fragmented females, and a redescription is presented here. Procyrnea fraseri n. sp. (Nematoda) is described, and distinguished from its congeners by its slender body shape and shorter spicules. Strigea falconis (Trematoda) is reported for the first time in New Zealand. Cladotaenia anomalis (Cestoda) and Polymorphus circi (Acanthocephala) were previously described as new species elsewhere. An unnamed species of capillariid appears to be mainly confined to North Island and is rare in South Island. Prevalence and intensity metrics are given, and DNA sequences provided to accompany new re/descriptions. Potential intermediate hosts are discussed, and the origins of the helminths and their potential for pathogenicity are considered.
Active learning of the collision distance function for high-DOF multi-arm robot systems
Authors: Kim Jihwan , Park Frank Chongwoo 
Published: January 2024

AbstractMotion planning for high-DOF multi-arm systems operating in complex environments remains a challenging problem, with many motion planning algorithms requiring evaluation of the minimum collision distance and its derivative. Because of the computational complexity of calculating the collision distance, recent methods have attempted to leverage data-driven machine learning methods to learn the collision distance. Because of the significant training dataset requirements for high-DOF robots, existing kernel-based methods, which require$O(N^2)$memory and computation resources, where$N$denotes the number of dataset points, often perform poorly. This paper proposes a new active learning method for learning the collision distance function that overcomes the limitations of existing methods: (i) the size of the training dataset remains fixed, with the dataset containing more points near the collision boundary as learning proceeds, and (ii) calculating collision distances in the higher-dimensional link$SE(3)^n$configuration space – here$n$denotes the number of links – leads to more accurate and robust collision distance function learning. Performance evaluations with high-DOF multi-arm robot systems demonstrate the advantages of the proposed active learning-based strategy vis-$\grave{\text{a}}$-vis existing learning-based methods.
Drivers of Air‐Sea CO2 Flux in the Subantarctic Zone Revealed by Time Series Observations

Published: January 2024

AbstractThe subantarctic zone is an important region in the Southern Ocean with respect to its influence on air‐sea CO2 exchange and the global ocean carbon cycle. However, understanding of the magnitude and drivers of the flux are still being refined. Using observations from the Southern Ocean Time Series (SOTS) station (∼47°S, 142°E) and auxiliary data, we developed a multiple linear regression model to compute the sea surface partial pressure of CO2 (pCO2) over the past two decades. The mean amplitude of the pCO2 seasonal cycle between 2004 and 2021 was 44 μatm (range 30–54 μatm). Summer minima ranged from 310 to 370 μatm and winter maxima were near equilibrium with the atmosphere. The non‐thermal (i.e., biological processes and mixing) contribution to the seasonal variability in pCO2 was several times larger than the thermal contribution. The SOTS region acted as a net carbon sink at annual time scales, with mean magnitude of 6.0 mmol m−2 d−1. The positive phase of the Southern Annular Mode (SAM) increased ocean carbon uptake primarily through an increase in wind speed at zero time lag. Increased surface pCO2 was correlated with a positive SAM with a lag of 4 months, mainly due to reduced biological uptake and increased mixing. During the autotrophic season, pCO2 was predominantly impacted by primary productivity, whereas water mass movement, inferred by temperature and salinity anomalies, had a larger impact on the heterotrophic season. In general, mesoscale processes such as eddies and frontal movement impact the local biogeochemical features more than the SAM.

AbstractThe Kuroshio intrusion (KI) is a northwestward‐flowing branch of the Kuroshio Current, which enters the South China Sea (SCS) and regulates its temperature, salinity, and water mass exchanges. However, limited direct observations hinder our understanding of KI's mechanisms and responses to climate change. Here, we present a 60‐year bi‐monthly resolved coral oxygen isotope (δ18Oc) record from Dongsha Atoll, the northern SCS. The dry‐season (December–March) δ18Oc record reveals interannual to decadal variabilities of the KI. The impact of the East Asian winter monsoon (EAWM) on Dongsha δ18Oc was more pronounced during the 1970s and 1980s and after the early 2000s, while the influence of the El Niño‐Southern Oscillation (ENSO) on Dongsha δ18Oc was higher between the 1980s and 1990s. The Pacific Decadal Oscillation (PDO) may have a relatively minor effect on KI strength or may indirectly modulate KI strength through its influence on ENSO activities. Our Dongsha δ18Oc record highlight the importance of the EAWM, ENSO, and PDO in predicting future KI changes.

Published: January 2024

AbstractInvestigating polymer degradation mechanisms enables the establishment of controlled degradation techniques for the development of sustainable and recyclable materials. Hydration can play a crucial role in controlling the hydrolysis of polymers. Here, ether-functionalized aliphatic polycarbonates (APCs) susceptible to nonenzymatic hydrolysis were developed for application as biocompatible biomaterials. Among these polymers, those grafted with 2-methoxyethyl and 3-methoxypropyl side chains via an amide group were highly wettable, strongly interacted with water, and experienced almost complete hydrolysis in phosphate-buffered saline over 30 days, which was attributed to the hydrogen bonding between water and the amide/methoxy groups. In an alkaline medium, all amide-linked APCs were completely hydrolyzed within 30 days, regardless of the side-chain structure. In contrast, the nonamide-linked APCs and a representative aliphatic polycarbonate, poly(trimethylene carbonate), were minimally degraded in the buffer and experienced <31% degradation under alkaline conditions. The APC with the 3-methoxypropyl side chain exhibited platelet adhesion properties comparable to those of ether-functionalized APCs previously reported as blood-compatible polymers. Thus, our results demonstrate the effects of an amide linker on the hydration and hydrolytic properties of APCs and can help establish new design concepts for degradable polymers.
Reanalysis of genomic data, how do we do it now and what if we automate it? A qualitative study
Authors: Fehlberg Zoe , Stark Zornitza , Best Stephanie 
Published: January 2024

AbstractAutomating reanalysis of genomic data for undiagnosed rare disease patients presents a paradigm shift in how clinical genomics is delivered. We aimed to map the current manual and proposed automated approach to reanalysis and identify possible implementation strategies to address clinical and laboratory staff’s perceived challenges to automation. Fourteen semi-structured interviews guided by a simplified process map were conducted with clinical and laboratory staff across Australia. Individual process maps were integrated into an overview of the current process, noting variation in service delivery. Participants then mapped an automated approach and were invited to discuss perceived challenges and possible supports to automation. Responses were analysed using the Consolidated Framework for Implementation Research, linking to the Expert Recommendations for Implementing Change framework to identify theory-informed implementation strategies. Process mapping demonstrates how automation streamlines processes with eleven steps reduced to seven. Although participants welcomed automation, challenges were raised at six of the steps. Strategies to overcome challenges include embedding project champions, developing education materials, facilitating clinical innovation and quality monitoring tools, and altering reimbursement structures. Future work can build on these findings to develop context specific implementation strategies to guide translation of an automated approach to reanalysis to improve clinical care and patient outcomes.

Published: January 2024

AbstractThis paper focuses on the operational analysis of wireless power transfer (WPT) system, while the topology of the secondary side rectifier represents the main element, for which the properties of WPT system are being investigated. Initially the system description and technical specifications are given. Because WPT systems are designed for a certain type and value of the load (impedance matching) in order to achieve the highest possible efficiency, the definitions for those values are identified for individual topologies of the secondary side rectifiers. Consequently, the results are compared and discussed and followed by the simulation analysis to prove the operational behavior in time-domain for each of investigated alternative of rectifier. Several relationships have been identified in relation to secondary side electrical variables, and discussion for stress-optimization are given as well. The simulation results are verified by the experimental measurements, while individual solutions for secondary side rectifiers are evaluated from efficiency point of view followed by the recommendations of the operational conditions.

AbstractPlant materials are a rich source of polyphenolic compounds with interesting health-beneficial effects. The present study aimed to determine the optimized condition for maximum extraction of polyphenols from grape seeds through RSM (response surface methodology), ANFIS (adaptive neuro-fuzzy inference system), and machine learning (ML) algorithm models. Effect of five independent variables and their ranges, particle size (X1: 0.5–1 mm), methanol concentration (X2: 60–70% in distilled water), ultrasound exposure time (X3: 18–28 min), temperature (X4: 35–45 °C), and ultrasound intensity (X5: 65–75 W cm−2) at five levels (− 2, − 1, 0, + 1, and + 2) concerning dependent variables, total phenolic content (y1; TPC), total flavonoid content (y2; TFC), 2, 2-diphenyl-1-picrylhydrazyl free radicals scavenging (y3; %DPPH*sc), 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) free radicals scavenging (y4; %ABTS*sc) and Ferric ion reducing antioxidant potential (y5; FRAP) were selected. The optimized condition was observed at X1 = 0.155 mm, X2 = 65% methanol in water, X3 = 23 min ultrasound exposure time, X4 = 40 °C, and X5 = 70 W cm−2 ultrasound intensity. Under this situation, the optimal yields of TPC, TFC, and antioxidant scavenging potential were achieved to be 670.32 mg GAE/g, 451.45 mg RE/g, 81.23% DPPH*sc, 77.39% ABTS*sc and 71.55 μg mol (Fe(II))/g FRAP. This optimal condition yielded equal experimental and expected values. A well-fitted quadratic model was recommended. Furthermore, the validated extraction parameters were optimized and compared using the ANFIS and random forest regressor-ML algorithm. Gas chromatography-mass spectroscopy (GC–MS) and liquid chromatography–mass spectroscopy (LC–MS) analyses were performed to find the existence of the bioactive compounds in the optimized extract.
