AbstractThe leaching and recycling of valuable metals via environmentally benign solvents is important because of the ever‐increasing waste lithium‐ion batteries, but it remains a challenge. Herein, a multi‐functional deep eutectic solvent (DES) based on lactic acid (LA) and guanidine hydrochloride (GHC) was used to extract cobalt and lithium ions from LiCoO2. Due to the strong acidity (protons) and abundant chlorine coordinating ions of LA/GHC, the solubility of LiCoO2 in LA/GHC could reach as high as 19.9 mg g−1 (stirred at 80 °C for 24 h), and a little LiCoO2 powder even could be dissolved at room temperature without stirring. Oxalic acid was used to strip and separate the oxalates of cobalt and lithium. Furthermore, LA/GHC could be recycled with a similar dissolving performance. This work avoided using corrosive acids and could be realized at low temperature (80 °C), making it energy‐saving and cost‐effective. It shows DESs have great potential in extracting strategically important metals from LiCoO2 cathodes and provides an efficient and green alternative for sustainable recycling of spent lithium‐ion batteries.

AbstractIn this paper, a reconfigurable double‐sided inductor‐capacitor‐capacitor (LCC)‐based data transfer method for wireless power transfer (WPT) system is proposed. The power and the data are, respectively, transferred through the orthogonal decoupled inductive links, and thus, the interference between the power transfer link and the data transfer link can be eliminated. Dual‐resonant frequency is used to exchange data in the binary frequency‐shift keying (2FSK) modulation. The performance of the reconfigurable LCC compensation topology is explored, and the design method is presented to improve the data transfer rate and to guarantee the similar data transfer characteristics under the two different frequencies. Thus, a stable data transfer can be guaranteed irrespective of the data type. The power transfer link and data transfer link are, separately, analyzed. Together with the well‐designed parameters, 512 W power with 115.2 kbps transfer rate half‐duplex communication is obtained, and the direct current–direct current (DC–DC) efficiency reaches 80.44%.

AbstractIn this paper, a couple inductor‐based dc‐dc boost converter with extensible capability is presented. In the proposed converter, attaching extensions to input section alleviates input current ripple. Furthermore, the current sharing performance between different phases operates beneficially by expanding optimized boost converters, especially when a partial inequality exists among different switches' duty cycles and leakage inductances. The voltage conversion ratio of the proposed converter is also additionally optimized by a series of VMR's output capacitors. Meanwhile, not only the voltage stress upon the main switches is decreased but also the all switches are managed to be turned on with zero current switching technique. The voltage spikes across MOSFETs are eliminated by using the recycling energy of leakage inductances on the clamp capacitor. The topology of the proposed converter, steady‐state analysis, and design procedure is presented to indicate the merits of the suggested converter. A prototype circuit with a three‐phase interleaved boost converter, two number of diode‐capacitor in each VMR, and output power 660 W and 40–800 V conversion ratio is experimented to corroborate the validity of the presented structure.

Published: July 2022

SummaryHeterogeneous wireless sensor networks (HWSNs) have a wide range of application in the contemporary world particularly in sensing and hunting of events without human interference. Due to this limitation of network resources and energy of sensor nodes, the contention of available resources for transmission will increase the energy consumption in the network and degrade the performance of Quality of Service. During dense traffic conditions, sensor nodes in close proximity to base station (BS) faces severe bottleneck resulting in congestion and energy hole problem. The efficient utilization of energy and packet loss is due to link break and by traffic analysis attack is a primary threat in HWSN applications. To sustain maximum energy in the network, two important aspects are considered, namely, flawless selection of path and concise clustering. This paper describes about a multi‐objective‐based Hybrid Diffusion Clustering Scheme (HDCS) through Jellyfish routing protocol with Time Division Multiple Access (JRP‐TDMA)‐based routing method in HWSN. Cluster head is elected based on multiple objectives such as residual energy, cost, and distance. Once CH selection is done, JRP‐TDMA based on available timeslot handpicks the best path for transmitting to BS. The proposed protocol is analyzed, simulated, and performance results are correlated with existing protocols namely, diffusion clustered routing protocol (DCRP), efficient unequal clustering (EEUC), Markov chain model‐based optimal cluster head (MOCH), and genetic algorithm (GA). The number of alive sensor nodes of proposed method has increased by 24.4% when compared with other approaches.

AbstractObjectiveAnorexia nervosa (AN) is a serious condition characterized by undernutrition, complicated by endocrine dysregulation, and with few predictors of recovery. Urinary free cortisol (UFC) is a predictor of weight gain, but 24‐h urine samples are challenging to collect. We hypothesized that serum dehydroepiandrosterone sulfate (DHEAS), which like cortisol is regulated by adrenocorticotropic hormone (ACTH), would predict weight gain and increases in fat mass in women with AN.MethodsWe prospectively studied 34 women with AN and atypical AN, mean age 27.4 ± 7.7 years (mean ± SD), who received placebo in a 6‐month randomized trial. Baseline DHEAS and 24‐h UFC were measured by liquid chromatography with tandem mass spectrometry. Body composition was assessed at baseline and 6 months by DXA and cross‐sectional abdominal CT at L4.ResultsMean baseline DHEAS level was 173 ± 70 μg/dl (0.7 ± 0.3 times the mean normal range for age) and mean baseline UFC (n = 15) was 20 ± 18 μg/24 h (normal: 0–50 μg/24 h). Higher DHEAS levels predicted weight gain over 6 months (r = 0.61, p < .001). DHEAS levels also predicted increases in fat mass (r = 0.40, p = .03), appendicular lean mass (r = 0.38, p = .04), and abdominal adipose tissue (r = 0.60, p < .001). All associations remained significant after controlling for age, baseline BMI, OCP use, duration of AN, and SSRI/SNRI use. DHEAS levels correlated with UFC (r = 0.61, p = .02).DiscussionIn women with AN, higher serum DHEAS predicts weight gain and increases in fat and muscle mass. Additional studies are needed to confirm these findings and further elucidate the association between DHEAS and weight gain.Public SignificanceAnorexia nervosa is a severe psychiatric condition, and predictors of weight recovery are needed to improve prognostication and guide therapeutic decision making. While urinary cortisol is a predictor of weight gain, 24‐h urine collections are challenging to obtain. Like cortisol, dehydroepiandrosterone sulfate (DHEAS) is a hormone produced by the adrenal glands. As a readily available blood test, DHEAS holds promise as more practical biomarker of weight gain in anorexia nervosa.

AbstractBackgroundWhile negative affect (NA) typically increases risk for binge eating, the ultimate impact of NA may depend on a person's ability to regulate their emotions. In this daily, longitudinal study, we examined whether emotion regulation (ER) modified the strength of NA‐dysregulated eating associations.MethodsWomen (N = 311) from the Michigan State University Twin Registry first reported dimensional binge eating symptoms and broad ER difficulties (e.g., limited emotional awareness, difficulty controlling emotional impulses). Participants then rated use of adaptive (cognitive reappraisal, social sharing, situation modification, and acceptance) and maladaptive (rumination, expressive suppression, and self‐criticism) ER strategies, emotional eating (EE), objective binge eating (OBE), and NA once daily for 49 consecutive days.ResultsThere were several main effects of ER on binge‐eating pathology in both between‐person (i.e., comparing women who differed on average) and within‐person (i.e., examining fluctuations in variables day‐to‐day) analyses. Between‐person, greater broad ER difficulties, greater maladaptive strategy use, and lower adaptive strategy use were all associated with greater binge‐eating pathology. Within‐person, greater maladaptive strategy use was associated with greater odds of OBE on that day and on the following day. However, neither broad ER difficulties nor use of specific strategies moderated associations between NA and dysregulated eating in between‐ or within‐person analyses.ConclusionsWhile ER is independently associated with risk for dysregulated eating, it may not fully mitigate the impact of NA. Additional strategies (e.g., decreasing environmental stressors and increasing social support) may be needed to minimize NA and its impact on dysregulated eating.Public SignificanceNegative affect (NA; e.g., sadness, guilt) increases dysregulated eating risk. Because NA is sometimes unavoidable, we examined whether emotion regulation (ER; i.e., how a person responds to their emotions) might impact whether NA leads to dysregulated eating. Although more effective ER was associated with less dysregulated eating overall, ER did not impact the association between NA and dysregulated eating. Other approaches may therefore be needed to mitigate NA‐dysregulated eating associations.
Greater sage‐grouse habitat selection varies across the marginal habitat of its lagging range margin

Published: July 2022

AbstractStudying wildlife–habitat relationships at the edges of their range can provide valuable insights into the environmental factors limiting wildlife distributions and most likely to drive extirpations and range shifts in response to landscape change. Yet the relative impact of those factors is likely different along the range margin, so it is important to identify the limitations to suitable habitat at both regional and local scales. Some of the most drastic impacts of large‐scale landscape changes in North America have occurred and are forecasted in the sagebrush steppe ecosystems, where species unable to seek new habitat in the fragmented landscape will be vulnerable to climatic extremes, vegetation community shifts, and anthropogenic land use change. One of the species likely under major threat from landscape changes is the greater sage‐grouse (Centrocercus urophasianus), a sagebrush obligate with habitat constraints that make it susceptible to habitat loss impacts as sagebrush systems contract and fragment at their southern range margin, already naturally fragmented. In this study, we evaluated factors of topography and land cover directly impacting habitat selection by sage‐grouse in four study areas along their lagging range edge. We used >116,000 GPS locations from >90 grouse across four study areas in southern Utah and Nevada from 2014 to 2020 in habitat selection analyses using random forest models. Our results showed that sage‐grouse exploit topography and sagebrush cover, possibly to break predator sight lines and moderate the risk posed by avian predators using tree perches, complicating the effects of tree cover and conifer encroachment into sagebrush habitat. We found similar trends across all four study areas, suggesting sage‐grouse along the southern range margin face similar limitations. However, the effects were nonlinear and varied—models trained in one study area were only moderately successful at predicting selection in others. The local idiosyncrasies along this southern range margin indicate a need for place‐based conservation for sage‐grouse and other potentially imperiled species. Incorporating new understandings of local impacts will refine regional and range‐wide models and support efforts to effectively create habitat and plan for range shifts by vulnerable species in response to environmental change.

AbstractHuman altered landscapes have caused declines in the diversity of wildlife where behaviorally plastic species (i.e., mesocarnivores and invasive species) tend to monopolize these areas and consume predictable and readily accessible food resources, such as human food waste and carrion. Increased consumption of carrion by vertebrates and invasive invertebrate species can alter population dynamics of native necrophagous insects relying on these resources. We tested the hypothesis that vertebrate scavengers and invasive species reduce blow fly (1) ability to use carrion and (2) reproduction in human‐impacted environments in central Texas, USA, with season, habitat (field and wooded landscapes), and carrion type (species of carrion and coat color) acting synergistically. Vertebrate scavengers in this habitat, of which 75% of the documented species were mesocarnivores and obligate scavengers, consumed 100% of carrion during the winter and 62% during summer despite having low species richness (2–5 species). Of the remaining carcasses available for arthropod activity during summer, the invasive red imported fire ant, Solenopsis invicta (Hymenoptera: Formicidae), monopolized 34%, and blow flies (e.g., Lucilia eximia and Chrysomya rufifacies [Diptera: Calliphoridae]) were only able to colonize 25%. Approximately 90% of carrion that was utilized by blow flies was co‐colonized by fire ants, and subsequent production of adult blow flies experienced up to a ninefold reduction in production compared with carcasses that were not scavenged by vertebrates or fire ants. Our results demonstrate oviposition resources used by blow flies in environments altered by human activity are reduced significantly by vertebrate scavengers and an invasive ant species. Future research should determine whether competitive interactions between vertebrate and invasive ant competitors for access to carrion resources have population‐level impacts to blow flies in human‐mediated ecosystems, or whether blow flies are able to shift to other resources to maintain sustainable populations and continue providing ecosystem services, such as pollination.

AbstractAimsTo describe logistics and outcomes of the accreditation program of centres of excellence in heart failure (HF) developed in Spain by the Spanish Society of Cardiology (SEC) between 2016 and 2021.Methods and resultsA scientific committee created by the SEC defined three types of HF units (community, specialized, and advanced), depending on the characteristics of the hospital and their portfolio of services and equipment, as well as the quality standards required for the accreditation of excellence. The units were required to submit to the SEC a document certifying compliance with the requirements and quality standards. Once verified these, the unit received accreditation of excellence from the SEC. Between 2017 and October 2021, 78 HF units spread throughout Spain applied for accreditation. This represents 50.6% of all Spanish national health system centres with cardiology departments. Accreditation was definitive in 56.4% of the applicant centres and provisional in the remaining 43.6%. Of the 78 units, 19 were community units, 44 specialized, and 15 advanced. Of the 34 units that received provisional accreditation for failure to meet any of the required quality standards, all resolved these deficits within 6 months of the initial evaluation, subsequently receiving definitive accreditation.ConclusionsOur experience indicates that implementation of an accreditation programme for excellence and quality of care of HF units at the national level by a scientific society is feasible and sustainable over time, leading the majority of HF units in the country to apply for accreditation and to meet the required quality standards.

AimsPeripartum cardiomyopathy (PPCM) remains a major contributor to maternal morbidity and mortality worldwide. The disease is associated with various complications occurring mainly early during its course. Reported adverse outcomes include decompensated heart failure, thromboembolic complications, arrhythmias and death. We sought to systematically and comprehensively review published literature on the management and outcome of women with PPCM across different geographical regions and to identify possible predictors of adverse outcomes.Methods and resultsWe performed a comprehensive search of relevant literature (2000 to June 2021) across a number of electronic databases. Cohort, case‐control and cross‐sectional studies, as well as control arms of randomized controlled trials reporting on 6‐ and/or 12‐month outcomes of PPCM were considered eligible (PROSPERO registration: CRD42021255654). Forty‐seven studies (4875 patients across 60 countries) met the inclusion criteria. Haemodynamic and echocardiographic parameters were similar across all continents. All‐cause mortality was 8.0% (95% confidence interval [CI] 5.5–10.8, I2 = 79.1%) at 6 months and 9.8% (95% CI 6.2–14.0, I2 = 80.5%) at 12 months. All‐cause mortality was highest in Africa and Asia/Pacific. Overall, 44.1% (95% CI 36.1–52.2, I2 = 91.7%) of patients recovered their left ventricular (LV) function within 6 months and 58.7% (95% CI 48.1–68.9, I2 = 75.8%) within 12 months. Europe and North America reported the highest prevalence of LV recovery. Frequent prescription of beta‐blocker, angiotensin‐converting enzyme inhibitor/angiotensin receptor blocker and bromocriptine/cabergoline were associated with significantly lower all‐cause mortality and better LV recovery.ConclusionWe identified significant global differences in 6‐ and 12‐month outcomes in women with PPCM. Frequent prescription of guideline‐directed heart failure therapy was associated with better LV recovery and lower all‐cause mortality. Timely initiation and up‐titration of heart failure therapy should therefore be strongly encouraged to improve outcome in PPCM.

AimsTo investigate the association between catheter ablation for atrial fibrillation (AF) and mortality as well as hospitalization for heart failure (HF) in patients with HF across the ejection fraction (EF) spectrum.Methods and resultsPatients with first‐time catheter ablation for AF (ablation group) compared to only medical treated AF patients (no ablation group) were identified from the Swedish Heart Failure Registry between 2005 and 2019. The primary outcome (all‐cause mortality/first HF hospitalization) was assessed by Cox regression models in a 1:2 propensity score (PS) matched cohort and pre‐specified EF subgroups (preserved EF [≥50%], mildly reduced EF [40–49%], reduced EF [<40%]) of this cohort. A total of 452 patients in the ablation group and 43 766 patients in the no ablation group were identified. After PS matching, 434 patients in the ablation group were compared to 868 patients in the no ablation group. Over a median follow‐up of 2.6 years (0.0–14.1 years), catheter ablation was associated with a lower risk of the primary outcome (all‐cause mortality/first HF hospitalization) (hazard ratio [HR] 0.78, 95% confidence interval [CI] 0.65–0.94). Results were consistent across all EF subgroups. In HF with preserved EF (HFpEF), catheter ablation was also associated with a lower risk of recurrent HF hospitalization (incidence rate ratio 0.17, 95% CI 0.07–0.42).ConclusionIn HF patients across the EF spectrum, catheter ablation for AF was associated with lower risk of the primary outcome (all‐cause mortality/first HF hospitalization). This study supports catheter ablation as a treatment option for AF in HF patients, including those with HFpEF.
