Summary
In theory, there is a trade‐off between hydraulic efficiency and safety. However, the strength and direction of this trade‐off at the leaf level are not consistent across studies, and habitat climate may impact this trade‐off.
We compiled a leaf hydraulic efficiency and safety dataset for 362 species from 81 sites world‐wide, with 280 paired observations of both traits, and tested whether climate was associated with departure from the proposed trade‐off.
The leaf hydraulic efficiency–safety trade‐off was weak (R2 = 0.144) at the global scale. Mean annual precipitation and solar radiation (SR) modified the trade‐off. Species from dry and high SR habitats (e.g. desert and tropical savanna) were generally located above the trade‐off line, indicating that these species tended to have higher leaf hydraulic safety and efficiency than species from wet habitats with low SR (e.g. subtropical monsoon forest and montane rainforest), which were located below the trade‐off line. Leaves with high vein density, dry leaf mass per area, and osmotic regulation enhanced safety without compromising hydraulic efficiency.
Variation in the hydraulic efficiency–safety trade‐off at the leaf level likely facilitates plant survival in specific habitats and allows for a more nuanced view of leaf hydraulic adaption strategies at the global scale.

Published: October 2024

ABSTRACTObjectiveCurrent surgical strategies for thoracic ossification of the ligamentum flavum (TOLF) are denounced by thoracic kyphosis, loss of spinal motion range, etc. A new surgical technique, laminoplasty and in‐site regrafting (LPIR), was modified to address the problems. This study aimed to report the safety and feasibility of LPIR for TOLF treatment.MethodsThis retrospective study reported the outcome of eight consecutive patients (3 males and 5 females, mean age 52.87 years) with TOLF who underwent LPIR surgery from January 2019 to March 2024. Pre‐ and post‐operative data including x‐ray, computerized tomography (CT), magnetic resonance imaging (MRI), the modified Japanese Orthopedic Association score (mJOA), the visual analog scale (VAS), and complications were collected to evaluate the outcome.ResultsAll surgeries were performed successfully, significantly alleviating symptoms postoperatively. During an average follow‐up period of 28.63 months, the VAS score reduced from 4.50 ± 1.00 pre‐operatively to 1.63 ± 0.48 on the third post‐operative day and further reduced to 0.50 ± 0.70 during the last follow‐up. The mJOA score increased from 3.63 ± 0.70 pre‐operatively to 6.13 ± 0.78 on the third postoperative day and further increased to 8.88 ± 1.27 during the last follow‐up. No severe complications were observed.ConclusionsLPIR exhibited significant safety and feasibility for treating TOLF, offering a novel strategy for managing this problem.

Published: October 2024

ABSTRACTSperm cryopreservation in small ruminant is an efficient strategy to distribute spermatozoa for reproductive programmes, but this process reduces the fertility potential of frozen–thawed spermatozoa. The aim of the current research was to evaluate the impact of different concentrations of cysteamine (CYS) in soybean lecithin (SL)‐based medium on postthawed buck semen quality and fertility potential. Semen samples were collected from five bucks, twice a week, then diluted in the SL‐based extender containing different concentrations of CYS as follows: extender containing 0 mM (control, C0), 1 mM (C1), 2 mM (C2), 4 mM (C4) and 8 mM (C8) CYS. Motility characteristics, membrane integrity, abnormal morphology, mitochondrial activity, acrosome integrity, viability, apoptotic‐like changes, lipid peroxidation, DNA fragmentation, ROS concentration, pregnancy rate and kidding rate were evaluated after freeze–thaw process. In results, C1 resulted in greater (p ≤ 0.05) total motility, progressive motility, average path velocity, membrane integrity, mitochondrial activity, acrosome integrity, viability, pregnancy rate and kidding rate compared to the other groups. Furthermore, supplementation of freezing medium with 1 mM of CYS presented lower (p ≤ 0.05) apoptotic‐like changes, lipid peroxidation, DNA fragmentation and ROS concentration compared to the other groups. On the other hand, C8 presented the least (p ≤ 0.05) total motility, progressive motility, average path velocity, membrane integrity, mitochondrial activity, acrosome integrity and viability as well as the highest (p ≤ 0.05) apoptotic‐like changes, lipid peroxidation, DNA fragmentation and ROS concentration compared to the other groups. Therefore, supplementation of freezing medium with 1 mM CYS could be a helpful strategy to protect buck's spermatozoa quality and fertility potential during cryopreservation process.
Attitudes toward statistics among business students: Do majors, mathematical background, sex, and field of secondary education matter?
Authors: Chu Patrick Kuok Kun 
Published: October 2024

AbstractStatistics knowledge, literacy, and skills are vital to undergraduates' academic and professional careers. Students' attitudes toward statistics play a vital role in their understanding of the importance of statistics. Therefore, it is important to examine their attitude toward statistics. This study investigated the attitude of 153 business students toward statistics and the factors that affect this attitude using the Survey Attitudes Toward Statistics (SATS‐36) scale. It also investigated the relationship between attitudinal components and students' demographic and academic characteristics. Five components underlying students' attitudes toward statistics were identified using exploratory factor analysis. Further, a background in quantitative subjects and demographic characteristics was found to affect students' attitudes toward statistics. The results suggested that statistics should be taught in a more practical way to relate it to students' lives, and teachers must adopt active learning methods in which students work with data and real‐life examples.
AXIAL DEFORMATION OF SPINEBIO-TENSEGRITY MODELAT DIFFERENT DEPLOYABLE SCHEMES

Published: October 2024

The study presents the axial deformation of a spine bio-tensegrity model through a shape change strategy with different deployment schemes. The spine bio-tensegrity model mimics the total height, tapered form and natural curvature of a human spine. Three deployable schemes S1-S3 with a different combination of cables at alterable and fixed lengths (at the lower, middle and upper part of the model, respectively) were investigated to achieve a series of axial displacements at 200 mm, 400 mm and 600 mm in the z-direction. The shape change algorithm was developed to optimise the forced elongation of cables, incorporating an objective function designed for monitored nodes in the system to reach their prescribed targets during the optimisation process. Sequential quadratic programming was employed to solve a nonlinear optimisation problem in the shape change analysis involving inequality constraints. The efficiency of the deployable schemes was evaluated based on the deformed shapes, convergence curve and axial forces of the spine bio-tensegrity model. The finding shows in addition to axial deformation, the model in deployment scheme S1 preserves the slenderness characteristic of the spine. In contrast, the model exhibits excessive expansion in the thoracic region in schemes S2 and S3. Greater total computational steps in deployment scheme S3, followed by S2 and S1, reveal that the active cables set near the monitored nodes allow the model to sense and act faster to reach their targets. The study contributes to understanding the structural behaviour and deployment strategy for a structure mimicking a biological system.
The Turán number of surfaces
Authors: Sankar Maya 
Published: October 2024

AbstractWe show that there is a constant such that any 3‐uniform hypergraph with vertices and at least edges contains a triangulation of the real projective plane as a subgraph. This resolves a conjecture of Kupavskii, Polyanskii, Tomon and Zakharov. Furthermore, our work, combined with prior results, asymptotically determines the Turán number of all surfaces.

Published: October 2024

Abstract
With advances in additive manufacturing (AM), the technology has significantly increased the applications in a wide range of industrial sectors. For example, stereolithography (SLA) has become a promising candidate for the mass production of energy absorption architected cellular materials due to its capability to fabricate complex material designs with advantageous characteristics. As stereolithography is being applied in different industrial settings, uncertainties become a critical factor that influences the performance of the products. As a solution, uncertainty quantification (UQ) is needed to understand the impact of uncertainties on the overall performance variability of the design and inform decision-makers to enhance system robustness and reliability better. This paper presented a novel framework for accelerated uncertainty quantification based on integrating physics-based computational modeling and data-driven surrogate models. The high-fidelity finite element model can be built and validated based on experimental tests. With an adaptive sampling technique, the surrogate model can be built with fewer expensive simulation runs while achieving a desirable modeling accuracy, saving the computational cost. Then, uncertainty quantification can be conducted accordingly using the developed surrogate model, which provides insights for the design and manufacturing decision-making processes of the architected cellular materials utilizing the additive manufacturing technology.

Published: October 2024

AbstractWe study the prospect of heavy singlet neutrinos as a dark matter (DM) candidate within a neutrinophilic U(1) model, where the Standard Model (SM) is extended with a U(1) gauge symmetry, and neutrino mass and oscillation parameters are explained through an inverse see-saw mechanism. The lightest of the heavy neutrinos plays the role of the DM, while the newly introduced scalars and the extra gauge boson $$Z'$$

act as mediators between the dark sector and the SM sector. We show the range of model parameters where this DM candidate can be accommodated in the Weakly Interacting Massive Particle (WIMP) or Feebly Interacting Massive Particle (FIMP) scenario. The observed DM relic density (DMRD) is achieved via the new gauge boson and singlet scalar portals in the WIMP scenario, whereas within the FIMP scenario, these two particles assume a distinct yet pivotal role in generating the observed DMRD.
Global, Regional, and National Burden of Nonrheumatic Valvular Heart Disease and Its Attributable Risk Factors in 204 Countries and Territories, 1990 to 2019: Results From the Global Burden of Disease Study 2019

Published: October 2024

Background
Nonrheumatic valvular heart disease (NRVD) is increasingly becoming a significant public health concern, particularly among older people. In the context of population aging, a detailed report on the epidemiological trends of NRVD is crucial for policymakers to effectively allocate health care resources. This study aimed to explore these trends using data from the GBD (Global Burden of Disease) 2019 study.

Methods and Results
We assessed the changing trends of the incidence, mortality, and disability‐adjusted life years rates for NRVD by calculating the estimated annual percentage change for each. Additionally, we examined the impact of a region's level of social development on NRVD epidemiological trends and identified key risk factors contributing to NRVD‐related deaths. Between 1990 and 2019, the global incidence of NRVD showed a gradual increase, with an estimated annual percentage change of 0.39 (95% CI, 0.30–0.48). The data revealed that women and older people are more likely to develop NRVD. High‐sociodemographic index countries exhibited higher age‐standardized incidence and mortality rates compared with low‐ and middle‐sociodemographic index countries. The most significant risk factor for NRVD‐related mortality was identified as high systolic blood pressure.

Conclusions
Over the past 3 decades, the burden of NRVD has intensified, indicating a need for more health care resources to address this issue, which is closely associated with an aging population. Currently, high‐sociodemographic index countries report the highest incidences and deaths due to NRVD. However, low‐ and middle‐sociodemographic index countries should also implement measures to manage the rapidly increasing burden of NRVD.
The Translating Subject: Self-Assertion and Edges of Mediation in Ali Ufkî’s Bilingual Dialogues
Authors: Yıldırım Duygu 
Published: October 2024

Abstract
Why did translation matter for early modern translators themselves? Approaching Ottoman court translator and religious convert to Islam, Ali Ufkî’s (né Wojciech Bobowski, ca. 1610–1677) intellectual endeavors, this article explores the multilayered relationship among translation, commensurability, and transmission of cultural knowledge by focusing on the translating subject. It argues that translation was an epistemic posture taken on by translators operating in complex cultural landscapes to navigate their self-assertion within the contours of cultural mediation in late seventeenth-century Istanbul. In so doing, it suggests reading translations beyond imperial logics and their concomitant historiographical terms.
The Two-Tier Problem
Authors: Wilkinson Dominic JC 
Published: October 2024

Abstract
A number of philosophers argue for a Two-Tier View: that there is some difference between individual-affecting and non-individual-affecting choices. But it is challenging to know the degree of moral difference, and to determine for some cases into which category they fall. I refer to this as the “Two Tier Problem.”
In this paper, I develop and defend a “Two-Tier Deontic View.” On that view, the higher tier applies to a subset of individual-affecting cases. We have stronger reason to bring about an individual-affecting rather than a non-individual-affecting benefit, but only in cases where we have agent-relative duties to the individuals so affected. In other cases (and I argue that this applies to most policy decisions affecting reproduction) there is no moral difference between individual- and non-individual-affecting choices.
Cyberspace and the Responsibility to Protect Populations from Atrocity Crimes
Authors: Neilsen Rhiannon 
Published: October 2024

Abstract
This article has two principal aims. First, it seeks to frame this special issue examining the intersection of cyberspace, digital platforms, and atrocity prevention frameworks – including the Responsibility to Protect (r2p). It does so by defining and scoping cyberspace, highlighting the limited extant research on cyber and atrocity prevention, and providing a brief overview of each article within this special section. By bringing together distinct perspectives – international law, political science, international relations, and policy – this special section hopes to ignite a timely, rich debate on 21st century technologies and atrocity prevention. Second, after setting the scene for the issue, this article offers its own novel contribution. In countering (continued) accusations of r2p’s irrelevance into the 2020s, this article argues that the norm’s three pillars must be re-examined in light of cyberspace. This is especially vital, as perpetrators of atrocities continue to employ cyber-enabled technologies and as r2p approaches its 20th anniversary.
Biographies and Revisionist Histories in Modern China
Authors: Chan Ying-kit 
Published: October 2024

Abstract
Born and raised in the British Caribbean island colony of Trinidad, Eugene Chen was one of China’s foremost foreign ministers during the early twentieth century, defending his nation’s interests despite its military weakness and political disunity. Relying primarily on newspapers and what he calls the “Eugene Chen Papers,” sourced from Eugene Chen’s grandson in Hong Kong, Walton Look Lai reveals Eugene Chen’s multiple identities, first as “Sun Yat-sen’s personal representative and spokesman in Shanghai,” then as “the global face and voice of the Wuhan regime,” and ultimately as “China’s ‘dynamite’ diplomat [who] challenged the British lion over the Hankow concession and won.” For many, Eugene Chen, for all his political accomplishments and connections to the most illustrious personalities in Republican Chinese history, cut a relatively obscure figure. Eugene Chen’s obscurity points to an old problem in Chinese historiography, or any historiography, for that matter. The privileging or canonization of certain historical figures at the expense of attention to others stems partly from the binary of reform and revolution held by historians when investigating the transformations of twentieth-century China or its transition from empire to nation. Walton Look Lai’s book on Eugene Chen is thus a contribution to our broader historiographical attempt to dismantle the obsolete paradigms that caricature complex historical personalities as one-dimensional persons of their times.
‘You should not be that good in week three:’ what can Strictly Come Dancing tell us about feedback and performativity in UK education policy?
Authors: Elbra-Ramsay Caroline 
Published: October 2024

The past decades have seen a plethora of TV reality talent shows emerge. The viewing population likes nothing more than seeing a ‘class’ of bakers, sewers, potters or dancers develop their skills and face the scrutiny of judges before being whittled down to a winner. The popularity of these shows says something about the national psyche but, aside from the entertainment value, may also carry conceptions of teaching, learning, assessment and feedback. By applying a metalinguistic thematic analysis to judges’ feedback, this paper seeks to examine how one UK show in particular, ‘ Strictly Come Dancing,’ presents feedback and, using a feedback framework, how this is understood. This feedback framework is notable for the links made to self-regulation, an area that continues to influence UK education policy. This paper will argue that when popular TV shows such as Strictly Come Dancing are viewed through a pedagogical lens, they reveal models of feedback which are not necessarily valued. Furthermore, analysis reveals the spectacle of normalised and broader educational neoliberalism policy reflected back at us.
Air Pollution and Energy Poverty: Evidence From Chinese Households
Authors: Li Xue , Smyth Russell , Yao Yao 
Published: October 2024

We estimate the causal effect of air pollution on energy poverty using Chinese panel data. Exploiting exogeneous variations in PM2.5 concentrations due to atmospheric thermal inversions to proxy air pollution, we find that poor air quality increases energy poverty at both the intensive and extensive margins. Specifically, we find that a one-standard-deviation increase in PM2.5 concentrations (22.06 μg/m3) increases the share of income spent on energy by 1.01 percentage points, accounting for 15.71 percent of the income share that a representative Chinese household spends on energy. The probability of being into energy poverty, in response to the same change, increases by 4.19 to 8.38 percentage points, which corresponds to a 22.57 to 34.01 percent increase in the proportion of households in energy poverty evaluated at the mean. Our results are robust to numerous checks. We find that the channels through which air pollution causes energy poverty are via people spending more time indoors, air pollution impairing health, and air pollution having an adverse effect on household income. Back-of-the-envelope calculations suggest that reducing PM2.5 emissions to the annual standard of 35 μg/m3, which is mandated by the central government, would lift 9.30 to 18.59 million households out of energy poverty.
