Low-Profile Double-Sided Metal-Backed H-Slot Folded-Patch Tag with Resonance Tuning Capability for On-Metal UHF RFID
Full text linkThis research article presents a miniature, simple in construction, low-profile, two-sided metal-backed folded patch antenna with a resonance tuning capability for on-metal UHF tag. A flexible single-layer polyethylene terephthalate (PET) substrate is wrapped around two pieces of polyethylene foam to support the fabrication of the designed tag. The top and bottom conductive layers are fully laminated with copper, enabling two sides of the tag to be placed against the metal surface without compromising its performance. An H-slot is etched in the middle patch, and the UCODE 8 flip chip is bonded across the center of the embedded patch. The middle patch and top conductive layers are shorted to the bottom conductive layer using inductive shorting stubs. The top conductive layer and the middle patch radiate effectively as a combined structure when the bottom conductive layer is mounted on a metal surface. Conversely, the bottom conductive layer and middle patch jointly radiate effectively when the top conductive layer is placed on the metal surface. Rigorous constrained optimization using the penalty function approach was employed to realize optimal performance with ideal impedance matching at the desired resonant frequency. Concurrent adjustment of all antenna parameters enabled the enhancement of operating parameters beyond what is possible using traditional means, especially in terms of miniaturization. The tag resonance can be tuned to the Lower European (LEu) band with minimal adjustment using single parameter tuning techniques: adjusting the horizontal parallel slots length (Tag-B) or adjusting the width of the shorting stubs (Tag-C). The tag’s volume and size are remarkably small (49.76 mm×18.14 mm×1.177 mm) while its high performance is sustained. The measured read performance on-metal surface is 9.5 m for 4 W EIRP in the NA spectra, whilst it is 7.36 m (Tag-B) and 6.79 m (Tag-C) for 3.24 W EIRP in the LEu spectra. The tag’s reading performance stays stable after being flipped on a metal surface
Vascular Disease as a Consequence of Impaired Endothelial Redox Adaptation
Full text linkEndothelial dysfunction plays a central role in cardiovascular and cerebrovascular disease, but its portrayal as a simple imbalance associated with oxidative stress and nitric oxide (NO) deficiency has somewhat hindered therapeutic progress over the years. Accumulating evidence supports a conceptual shift towards endothelial redox plasticity, the capacity of vascular endothelium to dynamically regulate NO synthase activity and reactive oxygen species (ROS) production during various physio-pathological processes, including growth, repair, and ageing. Experimental, genetic, and clinical data exhibit that ROS are required for physiological adaptation, and that pathology emerges from a regulatory imbalance rather than oxidative stress alone. Mechanistic studies have further exhibited that redox-sensitive signalling networks tightly coordinate endothelial survival, mitochondrial function, and inflammatory activation, reinforcing the concept that oxidative signalling is integral to vascular homeostasis rather than merely deleterious. Distinct vessel-specific redox profiles, microenvironmental factors, progenitor cell dysfunction, and cellular senescence further determine vascular resilience. Hence, restoration of redox adaptability offers a sound foundation for precision vascular therapies
CONSORT–Children and Adolescents (CONSORT-C) 2026 Extension Statement: Enhancing the Reporting and Impact of Pediatric Randomized Trials
Full text linkImportance Randomized controlled trials (RCTs) in children and adolescents provide evidence for patients, families, researchers, clinicians, regulators, funders, policymakers, and other interest holders to inform decisions about health care interventions and improve outcomes for young patients and their families. To critically evaluate, interpret, and apply trial results, readers require access to a complete and transparent report of what was planned, done, and found, taking unique considerations specific to children and adolescents into account. Harmonized guidance based on evidence and consensus is needed to optimize standardized reporting and reduce research waste in pediatric RCTs.Objective To develop a pediatric reporting guideline extension to the Consolidated Standards of Reporting Trials (CONSORT) 2025 guideline, CONSORT–Children and Adolescents (CONSORT-C) 2026, that supports comprehensive reporting and enhances the transparency, reproducibility, accuracy, and utility of published pediatric RCT reports.Evidence Review The Enhancing the Quality of Transparency of Health Research (EQUATOR) Network’s published framework primarily informed the development of CONSORT-C 2026. A literature review was conducted to generate a list of candidate reporting items. To obtain direct input from young people and family caregivers throughout the project, a Youth Advisory Group and a Family Caregiver Advisory Group were formed. An international Delphi study with a priori consensus thresholds, consensus meeting, group writing of the explanation and elaboration paper, and pilot testing were conducted.Main Outcomes and Measures Harmonized guidance based on evidence and consensus is needed to optimize standardized reporting and reduce research waste in pediatric RCTs. As an extension to the CONSORT 2025 statement, the CONSORT-C 2026 reporting guideline aims to improve the quality and completeness of reporting of pediatric RCTs that involve participants aged 0 to 19 years.Findings The new CONSORT-C 2026 guideline is an extension to the updated CONSORT 2025 statement and adds reporting items applicable to pediatric RCT reports involving children and adolescents aged 0 to 19 years. Developed in partnership with young people (aged 10-24 years) and family caregivers, CONSORT-C 2026 comprises 13 new items recommended to be reported in pediatric RCT reports in addition to the CONSORT 2025 items. The 13 new reporting items include 1 youth-generated and 6 youth-endorsed items. CONSORT-C 2026 can be considered a minimum set of reporting items applicable to pediatric RCT reports reflecting the priorities of clinicians, researchers, young people, family caregivers, and other interest holders.Conclusions and Relevance Widespread implementation and uptake of CONSORT-C 2026 should optimize the usability of trial results for these populations, improve the reproducibility of trial results, and reduce research waste

Unpacking adaptation lock-ins: Explaining the persistence of the adaptation gap
Full text linkClimate change adaptation is increasingly outpaced by accelerating climate risks, resulting in a persistent and widening adaptation gap. Many current interventions remain incremental and insufficient, failing to address the scale of transformation required. We argue that this shortfall is best understood through the concept of adaptation lock-ins—systemic constraints that both cause and result from maladaptation. These lock-ins generate self-reinforcing dynamics that trap institutions and policy systems in established trajectories, hindering more ambitious and forward-looking action. In this paper, we explore how a deeper understanding of lock-ins can help explain enduring adaptation deficits and structural barriers to sustainable change. We also discuss methodological approaches to identifying lock-in mechanisms and show how such insights can be mobilized to inform deliberate ‘unlocking’ strategies that enable more equitable and transformative adaptation pathways and sustainability transformations
m6A RNA Methylation Is Increased in Tumour Invasive Regions and Influences Invasive Capability and Chemotherapeutic Sensitivity in Adult Glioblastoma
Full text linkAdult glioblastoma multiforme (GBM) is the most common primary malignant brain tumour caused by multiple molecular factors. N6-methyl-adenosine (m6A) is an abundant RNA modification that governs cellular RNA metabolism. We hypothesise that changes in m6A-modified RNA and regulatory machinery such as the writer proteins, Methyltransferase 3 (METTL3) and WT1-associating protein (WTAP), the demethyltransferase protein, and Alpha-ketoglutarate dependent dioxygenase (FTO), are driving factors of GBM development and treatment resistance. Here, we investigated m6A-RNA spatial and quantitative abundance and expression of m6A effector proteins directly in GBM tissue and patient-derived low-passage primary adult GBM and low-grade glioma (LGG) cells, and explored the consequences of m6A-RNA disruption on GBM invasive capabilities, self-renewal and responsiveness to temozolomide (TMZ). We observed that METTL3, WTAP and FTO transcript and protein expression were significantly increased in cells derived from invasive regions of GBM tumours, and elevated WTAP and FTO expression significantly correlated with poor GBM patient survival. We further found that the abundance of m6A-modified RNA in GBM tumours was significant higher in rim and invasive tissue, as well as significantly higher in patient-derived cells from GBM tumour invasive regions. Functional depletion of these effector proteins significantly altered m6A levels on and the expression of the pluripotency stem cell marker SOX2 while also impairing self-renewal and cell invasion behaviour and increasing sensitivity to TMZ. The targeting of RNA modification regulatory mechanisms reveals novel therapeutic strategies aimed at improving clinical outcomes for GBM patients
Rapid transfer to specialist orthopaedic ward reduces mortality in hip fracture patients, but several factors reduce the ability to achieve the < 4-hour target
Full text linkPurpose: Hip fractures are one of the most common fracture types in adults. Rapid admission to orthopaedic wards from ED ( 4h), and then by 30-day mortality. Logistic regression analyses were performed to identify factors associated with delayed admission to specialist wards and to assess the independent effect of admission delay (over 4h) on 30-day mortality. Results: Out of 5937 patients for whom admission data were available, 19% (1131/5937) were admitted within 4h. Results showed that lower AMT score (OR 0.98, 95% CI: 0.96-1.00, p = 0.014), out-of-hours presentation (OR 1.27, 95% CI: 1.11–1.45, p < 0.001), and a higher Charlson Comorbidity Index (OR 1.05, 95% CI: 1.02–1.09, p = 0.003) were associated with an increased chance of admission delays exceeding 4h. Furthermore, admission delays of more than 4h (OR 1.44, 95% CI: 1.06–1.95, p = 0.02) were associated with increased 30-day mortality, controlling for the other risk factors. Conclusion: Timely admission of hip fracture patients over the age of 60 is critical to reduce 30-day mortality. Low AMT score, out-of-hours presentation, and multiple comorbidities impact the timeliness of admissions in our hospital, highlighting a need to address these factors to improve care for this population
Maximum residual strong monogamy inequality for multiqubit entanglement
Full text linkWe establish two inequalities, the weighted strong monogamy (WSM) and the maximum residual strong monogamy (MRSM), which sharpen the generalized Coffman-Kundu-Wootters inequality for multiqubit states. The WSM inequality distinguishes itself from the strong monogamy (SM) conjecture [B. Regula et al., Phys. Rev. Lett. 113, 110501 (2014)] by using coefficients rather than exponents to modulate the weight allocated to various -partite contributions. In contrast, the MRSM inequality is formulated using only the maximum -partite entanglement. We find that the residual entanglement of the MRSM inequality can effectively distinguish the separable states. We also compare the tightness of various SM inequalities and provide examples using a four-qubit mixed state and a five-qubit pure state to illustrate the MRSM inequality. These examples characterize the trade-off relations among entanglement components involving varying numbers of qubits. Our results provide a rigorous framework to characterize and quantify the monogamy of multipartite entanglement
Dynamics of AGN feedback in the X-ray bright East and Southwest 'arms' of M87, mapped by XRISM
No full textContext. AGN feedback plays a critical role in regulating gas cooling and star formation in massive galaxies and at the centres of galaxy clusters. As the central galaxy in the nearest cluster, M87 provides the best spatial resolution for disentangling the complex interactions between AGN jets and the surrounding environment. Aims. We investigate the velocity structure of the multitemperature X-ray gas in M87, particularly in the eastern and southwestern arms associated with past AGN outbursts, using high-resolution spectroscopy from XRISM/Resolve. Methods. We analyze a mosaic of XRISM/Resolve observations covering the core of M87, fitting single-and multi-temperature models to spectra extracted from different regions and energy bands. We assess the line-of-sight velocities and velocity dispersions of the hotter ambient and cooler uplifted gas phases, and evaluate systematic uncertainties related to instrumental gain calibration. Results. The hotter ICM phase, traced by Fe He-α emission, shows velocity dispersions below ∼ 100 km/s, and no significant velocity shifts between the arms and a relaxed offset region, suggesting limited dynamical impact from older AGN lobes. In contrast, the cooler gas phase appears to exhibit larger line of sight velocity gradients up to several hundred km/s as well as a higher velocity dispersion than the ambient hot phase, although these conclusions remain tentative pending improvements in the robustness of the gain calibration at lower energies. Conclusions. The first microcalorimeter-resolved map of gas dynamics in M87 supports the uplift scenario for the X-ray arms, with the cooler gas in the east and southwest seemingly moving in opposite directions along the line of sight. The kinetic energy is a small fraction of the gravitational potential energy associated with the gas uplift, and XRISM further suggests that AGN-driven motions may be short-lived in the hot ambient ICM. These constraints provide important input towards shaping future models of AGN feedback
A UK perspective on responsible education for responsible AI: a multidisciplinary review and evaluation framework
Full text linkResponsible Artificial Intelligence (RAI) education has emerged as a way of approaching the field of AI to address a host of concerns (Bentley et al., 2023). Many education providers have been releasing new RAI-related online courses, programmes, or toolkits. When combined with the issues emerging from the development, deployment, and use of AI, the expansion of RAI education and the proliferation of resources raise two critical questions. First, what can we learn about RAI from examining both the content and structure of publicly available RAI educational resources? Second, how might we understand the quality and impact of these RAI resources? We conducted a systematic search of UK RAI educational resources found online. We first present a descriptive analysis of 211 resources collected, including their type, format, cost, sector, audience, and type of provider. Furthermore, we describe our collaborative approach to analysing four pre-selected resources in-depth, from which we outlined an evaluation framework that we then employed for assessing the content of a subset of 47 resources. The five crucial areas of our framework could guide both learners and developers when approaching RAI resources
