High‐performance self‐healing epoxy by microencapsulated epoxy‐amine chemistry I: Properties of the adopted healant system
Authors: Zhu Mengzhang , Xiao Kaibin , Zhang He 
Published: September 2024

AbstractThe adopted healant has a significant impact on the final healing performance of self‐healing materials. Herein, the healant system, bisphenol‐F diglycidyl ether (BFDGE) and polytheramine JEFFAMINE T403, which possesses the capability of fully healing at room temperature (RT) for epoxy, was investigated in depth. The healing potential of this healant system and its healing benchmark after microencapsulation were systematically studied using a manual injecting method. It shows that the maximum and benchmark healing efficiencies respectively reach about 210% and 170% at RT for 48 h. The robustness of the cured healant was checked by studying the mechanical properties of BFDGE/T403. It verified that the tensile properties of the healant are stable after RT curing for 48 h. The curing degree of the healant was further characterized using differential scanning calorimetry by measuring the residual exotherm. It reaches 90% when the maximum healing performance is achieved and stabilizes at 95% thereafter. The results from the manually healing test, the tensile test, and the DSC test, are consistent with each other, which validate the robustness of BFDGE/T403 as healant for self‐healing epoxies.

AbstractPurposeIn children with acute respiratory distress syndrome receiving mechanical ventilation, the peak inspiratory pressure (PIP) is close to plateau pressure (PPLAT) when inspiratory flow approaches zero. We aimed to evaluate the reliability of PIP to estimate PPLAT in infants with severe respiratory viral infection (SRVI), characterized by increased airway resistance, and the accuracy of an equational model to estimates PPLAT (ePPLAT) based on PIP.MethodsThis was a retrospective observational study including mechanically ventilated children (1 to 24 month old) with SRVI, whose respiratory mechanics measurements were performed to evaluate PIP and PPLAT. The measured PPLAT was compared with the result of the equation: ePPLAT = PIP – [5.067 – (0.858 × static compliance) – (0.018 × inspiratory resistance) – (0.390 × pressure above positive‐end expiratory pressure) + (4.989 × inspiratory time)].ResultsThirty‐seven patients were included, with a median age of 3 (2–5) months. They presented a high inspiratory and expiratory resistance (136 ± 43 and 168 ± 66 cmH2O/L/s, respectively) and a moderate reduction in static compliance: 0.75 ± 0.3 mL/kg/cmH2O. PIP overestimated PPLAT (33 ± 3 and 26 ± 5 cmH2O, p = 0.01), with a mean difference of 7.3 ± 4 cmH2O. Moreover, the Bland‐Altman analysis demonstrated a mean difference between PPLAT and ePPLAT of 1.0 ± 4.0 cmH2O, with 95% limits of agreement of –6.9 and 8.8.ConclusionsA significant difference between PIP and PPLAT was observed in infants with SRVI. The equation model was inaccurate for estimating PPLAT based on PIP. Any estimation of PPLAT from PIP needs to consider the resistance component of the respiratory system.

AbstractObjectivesThe objective of the study was to compare the effectiveness of combined exercise training during different menstrual phases on pain, quality of life and menstrual symptoms.MethodsA total of 72 participants for the study were randomly assigned into three groups: Group 1 (N = 24), Group 2 (N = 24) and Group 3 (N = 24) which had undergone combined exercise training during the follicular, luteal and bleeding phases of their menstrual cycle, respectively. The treatment programme included combined exercise training involving deep breathing exercises, Kegel exercises, core strengthening exercises and stretching exercises. Exercises were repeated 5 times with hold duration of 15 s with total of 30–40 min session with 5–10 min of warm‐up and cooldown sessions. Demographic data and outcome measures (Visual Analogue Scale [VAS], Menstrual Symptom Questionnaire [MSQ], and Working ability, Location, Intensity, Days, Duration [WaLIDD]) were assessed at baseline and assessed again during the first menstrual cycle after the completion of the treatment programme. One‐way ANOVA was used for between‐group comparisons of the normally distributed data.ResultsWithin‐group comparison of the outcome variables except VAS in group 3 showed a statistically significant difference in all groups. Comparison of post‐intervention results of the outcome measures of all the groups revealed a statistically significant difference for the VAS, while there was no statistically significant difference for in between the comparison of the WaLIDD and MSQ scoring.ConclusionCombined exercise training is effective in reducing pain only when performed during follicular and luteal phases and significantly improve quality of life and menstrual symptoms in all phases of the menstrual cycle.

AbstractEffective suppression of gastric acid secretion promotes healing of erosive esophagitis. Treatment guidelines recommend proton pump inhibitors (PPIs) and histamine H2–receptor antagonists (H2RAs). Emerging evidence also supports potassium‐competitive acid blockers (P‐CABs). The aim was to construct a mathematical model to examine the relationship between pH holding time ratios (HTRs) and erosive esophagitis healing rates with H2RAs, PPIs and P‐CABs. By literature search, we identified studies of H2RAs, PPIs or P‐CABs that reported mean pH >4 HTRs at steady state (days 5–8) and erosive esophagitis healing rates after 4 and/or 8 weeks. We aggregated treatments by drug class and developed a non‐linear, mixed‐effects model to explore the relationship between pH >4 HTRs and healing rates. The pH dataset included 82 studies (4297 participants; 201 dosage arms); healing rate data came from 103 studies (43,417 patients; 196 treatment arms). P‐CABs achieved the longest periods with intragastric pH >4, and the highest healing rates after 4 and 8 weeks. The predicted probabilities of achieving ≥90% healing rates at 8 weeks were 74.1% for P‐CABs, 17.3% for PPIs and 0% for H2RAs. P‐CABs provide the longest duration with intragastric pH >4 and, accordingly, the highest healing rates of erosive esophagitis.

Published: September 2024

AbstractReliable forecasts of quasi‐stationary, recurrent, and persistent large‐scale atmospheric circulation patterns—so‐called weather regimes—are crucial for various socio‐economic sectors, including energy, health, and agriculture. Despite steady progress, probabilistic weather regime predictions still exhibit biases in the exact timing and amplitude of weather regimes. This study thus aims at advancing probabilistic weather regime predictions in the North Atlantic–European region through ensemble post‐processing. Here, we focus on the representation of seven year‐round weather regimes in sub‐seasonal to seasonal reforecasts of the European Centre for Medium‐Range Weather Forecasts (ECMWF). The manifestation of each of the seven regimes can be expressed by a continuous weather regime index, representing the projection of the instantaneous 500‐hPa geopotential height anomalies (A) onto the respective mean regime pattern. We apply a two‐step ensemble post‐processing involving first univariate ensemble model output statistics and second ensemble copula coupling, which restores the multivariate dependence structure. Compared with current forecast calibration practices, which rely on correcting the field by the lead‐time‐dependent mean bias, our approach extends the forecast skill horizon for daily/instantaneous regime forecasts moderately by 1 day (from 13.5 to 14.5 days). Additionally, to our knowledge our study is the first to evaluate the multivariate aspects of forecast quality systematically for weather regime forecasts. Our method outperforms current practices in the multivariate aspect, as measured by the energy and variogram score. Still, our study shows that, even with advanced post‐processing, weather regime prediction becomes difficult beyond 14 days, which likely points towards intrinsic limits of predictability for daily/instantaneous regime forecasts. The proposed method can easily be applied to operational weather regime forecasts, offering a neat alternative for cost‐ and time‐efficient post‐processing of real‐time weather regime forecasts.
Frontal effects on the rapid formation of a deep layer of marine fog and cloud in the NW Atlantic

Published: September 2024

AbstractRapid formation of a deep layer of fog and clouds extending to a height of 2 km was observed over Sable Island off Nova Scotia on 13–14 July 2019. This fog and cloud event was dominantly caused by the rapid intrusion of a trough from a cyclone over NE Canada. The trough quickly moved from SW–W to E–NE and encroached on the coastal waters of Nova Scotia. Due to the warm front in the trough, the air temperature increased up to 4 km in height with increased stability, while the sea‐level pressure at Sable Island dropped by 11 hPa within 12 hours. The moderate to strong winds turned counterclockwise from the N to the SE, converging with the SE winds maintained by the ridge located to the east. There was no indication of an advection‐type fog mechanism because the surface air temperature was not adjusted to the colder sea‐surface temperature that could have resulted in saturation of the surface air. The leading portion of a massive cloud band in the trough passing over Sable Island included precipitation before fog formation. The rain that evaporated in the unsaturated and warm subcloud layer effectively reduced the air temperature and significantly increased the wet‐bulb temperature in this layer. The cloud extended into the moist subcloud layer, while fog formed at 1400 UTC 13 July and lasted until 2327 UTC 13 July (with two brief periods of mist lasting less than two hours). The development of this deep layer of fog and cloud in the NW Atlantic was caused by evolving synoptic conditions through the simultaneous effects of a rapid trough intrusion over coastal waters with a massive cloud band, induced precipitation causing cloud deepening into the subcloud layer, and surface wind convergence forcing vertical mixing in a stable marine boundary layer.

Published: September 2024

AbstractScholars, practitioners, and policymakers are considering a circular economy (CE) to optimise resource utilisation and tackle issues linked to economic and environmental growth. This research investigates the association between entrepreneurial bricolage, frugal innovation (FI), technological turbulence, and the implementation of CE in Malaysia, an emerging market. The authors tested the hypothesised relationships using legged multi‐source data and analysed them using the Smart‐PLS‐SEM technique. Data revealed that entrepreneurial bricolage is important in encouraging FI and CE. Meanwhile, the mediating role of FI amplified the link between entrepreneurial bricolage and CE. Furthermore, the moderation of technological turbulence amplified the link between entrepreneurial bricolage, FI, and CE. The findings indicate that firms employing a bricolage approach, characterised by accessing, storing, combining, and utilising readily available resources, exhibit enhanced performance during periods of technological turbulence through the implementation of CE and FI.

Published: September 2024

Abstract2D Fe‐chalcogenides emerge with rich structures, magnetisms, and superconductivities, which spark the growing research interests in the torturous transition mechanism and tunable properties for their potential applications in nanoelectronics. Uniaxial strain can produce a lattice distortion to study symmetry breaking induced exotic properties in 2D magnets. Herein, the anomalous Raman spectrum of 2D tetragonal (t−) and hexagonal (h−) FeTe is systematically investigated via uniaxial strain engineering strategy. It is found that both t‐ and h‐FeTe keep the structural stability under different uniaxial tensile or compressive strain up to ± 0.4%. Intriguingly, the lattice vibrations along both in‐plane and out‐of‐plane directions exceptionally harden (softened) under tensile (compressive) strain, distinguished from the behaviors of many conventional 2D systems. Further, the difference in thickness‐dependent strain effect can be well explained by their structural discrepancy between two polymorphs of FeTe. These results can supply a unique platform to explore the vibrational properties of many novel 2D materials.
Conducting LixPOy Interface Generated From Insulating Residual Lithium Compounds on LiNi0.8Mn0.1Co0.1O2 Surface Improves Cycle Life and Assists in Fast Cycling

Published: September 2024

AbstractLiNi0.8Mn0.1Co0.1O2 (NMC811) is the most promising cathode material for future Li‐ion batteries (LIBs). However, the bulk and surface structural instabilities retard its commercial success. Surface chemical instability toward exposure to moisture (H2O and CO2) leads to the formation of residual lithium compounds (RLCs: Li2CO3, LiOH) on the surface. The alkaline RLCs form a resistive layer on the surface of NMC811 by undergoing parasitic side reactions with electrolytes. Herein, an “Adverse‐to‐Beneficial” approach is proposed to eliminate RLCs by chemically transforming them into a LixPOy (Li3PO4 and LiPO3) interface. The interface protects the NMC811 surface from moisture attack and unwanted side reactions with electrolytes. It enhances the cycle life by retaining 70% of the initial capacity after 300 cycles at a 0.5C rate and 60% after 500 cycles, even at a 5C rate in a voltage window of 3.0–4.3 V versus Li+/Li. The coexistence of two Li‐conducting phases lowers the voltage polarization of the kinetically sluggish H1 → M phase transition to unlock fast cycling, reduces cationic disorder, improves coulombic efficiency, enhances ion diffusion kinetics, and minimizes particle crack formation after long‐term cycling. Hence, the LixPOy interface yields multifaceted benefits in the storage, processing, and electrochemistry of NMC811.

Published: September 2024

AbstractA 10‐year‐old, neutered, male labrador retriever was referred for acute history of abdominal pain and distention, pyrexia and pelvic limb ataxia. Peritoneal free fluid with intracellular bacteria was confirmed, and subsequent abdominal computed tomography revealed a hypoattenuating and rim‐enhancing focal lesion in the cortex of the left kidney, with associated regional inflammation. The dog underwent fine‐needle aspiration of the lesion with ultrasound guidance confirming the presence of a renal abscess with growth of Escherichia coli on culture of the acquired purulent intralesional fluid. Medical management was commenced, and on repeat clinical examination and computed tomography imaging, the clinical signs and renal lesion had resolved. To the authors’ best knowledge, this is the first report of confirmation of complete resolution of a cortical renal abscess, treated with only medical management, using computed tomography examination.
Political entrepreneurs and interest groups in the CPTPP ratification process in Chile: A case of politicization?
Authors: López Dorotea , Dockendorff Andrés , Lodato Simón 
Published: September 2024

AbstractThis study examines the strategies employed by Chilean political parties and interest groups to politicize the Trans‐Pacific Partnership (CPTPP). To achieve this goal, political entrepreneurs and anti‐trade lobbies opposed the CPTPP are using a distinct strategy to shape the debate. The idea of trade politicization helps understand how these key actors expanded the scope of topics, mobilizing political action from various groups such as environmentalists, unions, indigenous activists, and advocates for gender equality. Furthermore, this strategy involves shifting the discourse away from the traditional dichotomy of free trade versus protectionism and redirecting the debate toward ideological and cultural dimensions such as legitimacy and sovereignty.
Enhancing Well-Being Education Through Innovative Management
Authors: Todorut Amalia Venera 
Published: September 2024

AbstractEducational well-being is an innovative, multidimensional, complex, inspirational, and fluid concept, which generates performance at the individual and the institutional level, with direct effects on the quality of life. It is also a challenge and a responsibility for the management and leadership of any organization since innovative techniques, tools, and practices have to be developed and applied in order for educational well-being to be successful in the increasingly hostile, turbulent, volatile, and ambiguous environments the modern world is facing with profound and rapid transformations on all levels of social life. For these reasons, well-being has become an important field of scientific research in education. It requires a social and emotional remodeling of all actors involved, so that learning is sustainable and effective, based on achieving motivation, satisfaction of one’s work and life. Thus, in the context of creating a culture of well-being in schools or universities, it is necessary to design the mechanisms, relationships, rules, resources, and managerial processes through which the activities generating well-being are well thought out and monitored, aiming for an optimal allocation of all categories of resources in order to achieve the objectives. The paper aims to develop an innovative management and leadership process, based on human values that favor the creation of an optimal social and psychological climate for the development of well-being in any school or university, as a premise that generates value, efficient learning, and sustainable development. Thus, during the work I highlighted the need to identify the objectives, priorities, and key stakeholders, leading to the development of a strategy and an implementation plan, as well as monitoring the progress regarding the improvement areas. In this respect, I developed a well-being model based on four pillars, i.e., learning, support, work, and life. The research methodology is based on scientific investigation of specialized literature, indexed in international databases, through the analysis of numerous articles, studies, and indexes related to this field, published between the years 2019 and 2022. The on-going, empirical investigation involved applying a questionnaire addressed to teachers from schools and universities in the South-West Oltenia region and analyzing the response data.
Take No Shortcuts! Stick to the Rubric: A Method for Building Trustworthy Short Answer Scoring Models

Published: September 2024

AbstractThis paper introduces a new strategy to enhance the trustworthiness of Short Answer Scoring (SAS) systems used in educational settings. Although the development of scoring models with high accuracy has become feasible due to advancements in machine learning methods, particularly recent Transformers, there is a risk of shortcut learning using superficial cues present in training data, leading to behaviors that contradict rubric standards and thus raising issues of model trustworthiness. To address this issue, we introduce an efficient strategy that aligns the features of responses with rubric criteria, mitigating shortcut learning and enhancing model trustworthiness. Our approach includes a detection method that employs a feature attribution method to identify superficial cues and a correction method that re-trains the model to align with annotations related to the rubric, thereby suppressing these superficial cues. Our quantitative experiments demonstrate the effectiveness of our method in consistently suppressing superficial cues, contributing to more trustworthy automated scoring of descriptive questions.
Self-dualities and Galois symmetries in Feynman integrals

Published: September 2024

Abstract
It is well-known that all Feynman integrals within a given family can be expressed as a finite linear combination of master integrals. The master integrals naturally group into sectors. Starting from two loops, there can exist sectors made up of more than one master integral. In this paper we show that such sectors may have additional symmetries. First of all, self-duality, which was first observed in Feynman integrals related to Calabi-Yau geometries, often carries over to non-Calabi-Yau Feynman integrals. Secondly, we show that in addition there can exist Galois symmetries relating integrals. In the simplest case of two master integrals within a sector, whose definition involves a square root r, we may choose a basis (I1, I2) such that I2 is obtained from I1 by the substitution r → −r. This pattern also persists in sectors, which a priori are not related to any square root with dependence on the kinematic variables. We show in several examples that in such cases a suitable redefinition of the integrals introduces constant square roots like $$ \sqrt{3} $$

. The new master integrals are then again related by a Galois symmetry, for example the substitution $$ \sqrt{3} $$

3

→ $$ -\sqrt{3} $$

. To handle the case where the argument of a square root would be a perfect square we introduce a limit Galois symmetry. Both self-duality and Galois symmetries constrain the differential equation.
