We investigate seismic discontinuities across the middle of Earth’s mantle beneath a large seismic array that spans the North American continent. We provide robust constraints on the depth distribution, sharpness, and spatial variation of seismic discontinuities by processing high-resolution Ps-converted seismic waves (~0.5 Hz) through a novel denoising filter called CRISP-RF (Clean Receiver function Imaging with Sparse Radon Filters). In the upper mantle, above the mantle transition zone (MTZ), we observe a sharp velocity decrease at depths that vary from ~290 km to ~390 km. In the lower mantle, below the MTZ, we observe another sharp velocity decrease at depths that vary from ~800 km to 1,200 km.  The lower-mantle discontinuities cluster at a depth of ~885 km, while deeper converters (> 1,000 km) are less likely. The spatial distribution of these seismic features appears stochastic, but we detect collocated upper-mantle and lower-mantle discontinuities only at 8% of observed locations. We interpret our results with a dehydration melting model, in which MTZ water is transported into either the upper or the lower mantle, but rarely simultaneously, during Earth’s long history of subduction and mantle upwelling. 

Efficacy and safety profile of animal dander immunotherapy: a multicentre UK studyTo the Editor,The prevalence of animal dander sensitisation has increased worldwide, with sensitisation rates in Europe as high as 26.3% to cat dander and 27.2% to dog dander.1 These aeroallergens can be found in environments such as schools, public transport or places of work, where the animals do not live and sensitisation may occur by direct or indirect contact.2 The recommended treatment for most patients in the UK is avoidance, which is not always practical or possible, particularly in public areas or places of work.Evidence for animal dander allergen specific immunotherapy (AIT) is limited, with cat dander AIT demonstrating the most consistent improvement after 12 months in a small study.3 Studies of dog dander AIT over the past 40 years have not confirmed statistically significant clinical efficacy.3,4 Other therapies described include horse dander and rat epithelium AIT.5,6In view of the limited data on animal AIT, we conducted a multi-centre review. Data on 35 patients aged 17 to 62 years (demographics in Table s1) treated with cat, dog and horse dander subcutaneous (SCIT) or sublingual (SLIT) AIT within five allergy services was analysed. All patients had confirmation of sensitisation by specific IgE or skin-prick testing. The commonest reason for AIT was workplace exposure, almost a third of which were veterinary workers (Supplementary Table s2). Efficacy was measured with different methods across different patients (Table 1). Side effects are reported in Table 2.Our data shows a higher compliance rate for SCIT patients, with 3-year completion rates at 60% compared with SLIT at 43%, accounting for 4 patients currently on treatment, which aligns with published data (Table 1). The most common reason for incomplete therapy was loss to follow-up and there were varied reasons for this (Supplementary table S3).For those who completed the full 3-year therapy, there were excellent efficacy rates for both SCIT and SLIT with 100% of patients achieving either complete or partial response (Table 2). Patient reported symptoms was the most used indicator of efficacy. A negative in-hospital cat challenge was performed in one patient and a negative home dog provocation in one patient. Efficacy was better in SCIT, with 100% complete response compared with 67% complete response in SLIT. All products established a complete response, except Oralvac cat and horse.The side effect profiles were acceptable with only one patient receiving cat dander SCIT reporting systemic side effects of rhinitis and wheeze during updosing. This patient completed updosing but did not complete maintenance therapy due to side effects. The majority of reported side effects were limited to localised reactions (Table 2). 3 SLIT patients withdrew from treatment due to undocumented side effects. Overall, 23/35 (66%) patients reported no side effects.Although numbers are small, our data demonstrates significant benefits from animal dander AIT with high efficacy rates, and side effects mainly limited to mild, localised reactions. The therapy may be most beneficial in those who are unable to avoid exposure, most commonly from workplace, or those suffering from systemic symptoms, such as asthma exacerbations when exposed to dander without the presence of the animal itself, making avoidance near impossible. Despite the benefits, animal dander AIT is used less than other inhalant allergens.One limitation of the study is that we do not have long-term follow-up data, so the durability of the response is uncertain. Adherence is also a significant issue and means to improve this should be considered.There is limited research on animal dander AIT compared with other aeroallergens, and our data has shown positive findings, although mostly with cat and dog dander. Larger cohorts are required to understand the full benefits of animal dander AIT.Table 1. Documented efficacy and compliance rates for those who completed 3 years AIT therapy.

Note:  Oligophenylene  vanillin  nanowires  have a structure that   has an amazing length-to-width ratio .  Nanowires are very thin - it is possible to create nanowires with a diameter of only one nanometer,  nanowires are used to create the smallest transistor (nanotransistors).Oligophenylene vanillin  nanowires can  have   insulating, semiconducting or metal properties . Insulators do not carry electrical charges, while metals carry very good electrical charges.  Semiconductors lie between the two and are charged under the right conditions.   By placing semiconductor wires in the right configuration, transistors can be made that either  act as switches  or  amplifiers  . Some of the interesting and anti-flexible properties of nanowires are due to their small scale.

Device-to-device (D2D) underlay networks help in improving the spectrum efficiency of cellular networks by enabling nearby devices to perform direct communication through sharing of network resources with the cellular devices. Such networks can therefore be used to offload cached popular contents (such as videos), thereby improving the quality-of-experience (QoE). However, offload probability largely depends on the availability of the desired contents in nearby UEs and the mode of UE viz., cellular user equipment (CUE) and D2D user equipment (DUE). We study the dynamics of a D2D network by modeling the states of UEs as queuing system and identify its steady-state that help in (i) finding the expected stall-ratio under the steadystate, and (ii) understanding the factors affecting QoE, such as device density.

For citrus trees cultivated by dwarf dense planting, the fruits are randomly distributed in space, which poses difficulties for mechanized picking. To improve picking efficiency, a citrus picking system based on dual robot collaboration is designed and a global scanning picking scheme that scans the entire fruit tree to achieve orderly fruit picking is proposed in this research. The dual-robot calibration with the iterative method and closed-form method is completed in the research. The picking problem is attributed to the single traveling salesman problem, and the trajectory planning and the picking task are completed with genetic algorithm in the research. The picking experiments are designed in the research. As a result, in the picking experiments, the average time for planning the picking sequence of citrus was 0.1184 seconds. In each group of citrus picking experiments, the total picking time averaged 158.9 seconds, the picking success rate is 82%. The picking results show that the built dual-machine system can effectively complete the picking task. The proposed dual-robot picking system can provide a reference for the establishment of other picking robot system.

The integration of artificial intelligence into commercial applications has revolutionized various industries, offering unprecedented capabilities and efficiencies. However, the vulnerabilities associated with large language models, particularly in the context of prompt extraction threats, present significant security challenges that must be addressed to protect sensitive information and maintain user trust.

An automated threat simulation was employed to systematically test the model's response to crafted prompts, and the results were analyzed using quantitative metrics to assess the severity and success of information extraction. The study's findings revealed substantial risks, with the highest extraction success rates observed in educational and content creation contexts. The implications for data privacy and model security are profound, emphasizing the need for advanced defensive strategies and continuous improvement in LLM deployment. This research offers a structured framework for evaluating LLM security and provides actionable insights for developing more resilient models, ultimately contributing to safer and more reliable AI applications.

Motivation is considered a crucial factor in determining emotion regulation choice (ER choice). Our previous study revealed that increased motivation led to a preference for distraction over reappraisal due to the narrowed attention, yet neural underpinnings supporting this phenomenon remain unclear. In this study, we used event-related potentials (ERPs) to investigate whether motivation influences ER choice by early attention processing (P2) or late resource engagement (LPP). EEG activities were recorded for the pictorial contexts varying in motivational intensity and direction, while participants (N=68) were required to decide which strategy from the two options they would use to regulate their emotions. Consistent with previous studies, the results indicated that individuals chose more distraction over reappraisal in high-withdrawal motivated contexts while a reversed pattern was observed in low-withdrawal motivated contexts. Moreover, high-intensity motivated emotional contexts result in enhanced P2 and LPP. Further analysis indicates that only frontal P2 and the early LPP mediate the effect of motivational intensity on ER choice. These findings suggest that heightened motivation leads to a preference for distraction over reappraisal during emotion regulation due to the greater occupation of attentional resources.

Background: Pediatric palliative care (PPC) is associated with improved end-of-life (EOL) outcomes. Inpatient and outpatient PPC have unique roles during the disease course. Yet, it is unknown whether the location of PPC receipt (inpatient vs outpatient) is associated with healthcare utilization and EOL outcomes for pediatric oncology patients. Procedure: A retrospective single-institution chart review of pediatric patients (age 0-28) with cancer who died between January 2015 – December 2022 was performed to compare EOL outcomes and healthcare utilization metrics among only inpatient PPC, any outpatient PPC, and non-PPC recipients. Demographics and clinical factors were analyzed by location of PPC receipt. Results: Among 450 patients, 292 (64.9%) received PPC (inpatient only (35%), any outpatient (65%)). The proportion of patients who died without receiving PPC dropped from 69% to 22% following development of an outpatient PPC clinic (p<0.001). In the last six months, one month and week of life, inpatient PPC recipients spent more days admitted to the hospital and intensive care unit (all p<0.001), and had more intensive medical interventions performed (p<0.01). Outpatient PPC recipients were less likely to receive IV chemotherapy (p<0.01) or intubation (p=0.05), and more likely to receive hospice, die at home, and have an outpatient Do-Not-Resuscitate order (all p<0.001). Conclusions: PPC receipt substantially increased after the creation of an outpatient PPC clinic, suggesting that outpatient PPC is critical in the provision of PPC to children with cancer. Outpatient PPC was associated with fewer hospital days, IV chemotherapy and intubation at EOL, while improving hospice enrollment and home death.

The availability of fresh water over land may become increasingly scarce under climate change, and natural and human-induced tree cover changes can further enhance or negate the water scarcity. Previous studies showed that global tree cover change can have large impacts on water availability under current climate conditions, but did not touch upon the implications of global tree cover change under climate change. Here, we study the hydrological impacts of large-scale tree cover change (climate-induced changes in combination with large-scale afforestation) in a future climate (SSP3-7.0) following an interdisciplinary approach. By combining data from five CMIP6 climate models with a future potential tree cover dataset, six Budyko models, and the UTrack moisture recycling dataset, we can disentangle the impacts of climate change and future tree cover change on evaporation, precipitation, and runoff. We quantify per grid cell and for five selected river basins (Yukon, Mississippi, Amazon, Danube, and Murray-Darling) if tree cover changes enhance or counteract the climate-driven changes in runoff due to their impact on evapotranspiration and moisture recycling. Globally averaged, the impacts of climate change and large-scale tree cover change on runoff are of similar magnitude with opposite signs. While climate change increases the global runoff, the changing tree cover reverses this effect which overall results in a limited net impact on runoff relative to the present climate and current tree cover. Nevertheless, locally the change in runoff due to tree cover change and climate change can be substantial with increases and decreases of more than 100 mm yr −1. We show that for approximately 16 % of the land surface, tree cover change can increase the water availability significantly. However, we also find that, for 14 % of the land surface, both tree cover change and climate change might decrease water availability with more than 5 mm yr −1. For each of the selected catchments, the direction and magnitude of the impacts of climate change and tree cover change vary, with dominating climate change impacts in all basins except the Mississippi River basin. Our results show that ecosystem restoration projects targeting an altered tree cover should consider the corresponding hydrological impacts to limit unwanted (non-)local reductions in water availability.

INTRODUCTIONDelirium is an acute and transient brain dysfunction characterized by attention disorders, disturbance of consciousness levels, and changes in cognitive function, often with noticeable fluctuations. Postoperative delirium (POD) typically occurs within 24 to 72 hours after surgery.1 The incidence of delirium after vascular surgery ranges from 5% to 39%.2 However, delirium with unilateral pupil dilation has never been reported. The appearance of pupil dilation in patients with delirium brings serious difficulties to clinical diagnosis. Here, we report an unusual case of severe delirium with unilateral reversible pupil dilation after interventional thrombectomy of the lower extremity.

Artificial intelligence has revolutionized various fields through its ability to process and generate human-like text, leading to significant advancements in tasks requiring language comprehension and generation. However, the evaluation of fundamental reasoning abilities within commercial LLMs, specifically in inductive and deductive reasoning, remains crucial for understanding their cognitive capabilities and limitations. This research provides a comprehensive assessment of ChatGPT, Gemini, and Claude, using a meticulously designed set of reasoning tasks to evaluate their performance. The methodology involved the selection of diverse datasets, the design of complex reasoning tasks, and the implementation of a robust automated testing framework. Statistical analyses, including ANOVA and regression techniques, were employed to rigorously compare the models' performance across different tasks. Results indicated that ChatGPT consistently outperformed the other models, particularly excelling in tasks requiring high precision and recall, while Gemini and Claude exhibited variability in their reasoning capabilities. The study highlights the strengths and weaknesses of each model, offering insights into their relative performance and potential areas for improvement. Implications for AI development are significant, emphasizing the need for tailored model designs and continued innovation in training techniques to enhance reasoning abilities. This research contributes to the broader understanding of AI reasoning, providing a foundation for future advancements in developing more capable and reliable intelligent systems.

Pinus brutia (pine) and Cupressus sempervirens (cypress) are two important forestry species in the Mediterranean region, with different strategies to cope with water stress. The overall goal of this study is to investigate ecohydrological processes of these two species. Specific objectives are: (i) to quantify their transpiration; (ii) to analyze relations between meteorological variables, soil moisture, sap flow, leaf conductance and twig water potential; and (iii) to assess differences in soil water balances and dynamics between three canopy cover conditions (under canopy, edge of canopy, open area). The study site is a plantation forest in Athalassa Forest Park, in Cyprus with a long-term average annual rainfall of 315 mm. The site was converted from rainfed agriculture in 2011. Observations of sap flow (12 trees for 20 months, 4 trees for 24 months) and soil moisture (66 sensors, 24 months) were made hourly. Soil moisture sensors were installed under the tree canopy, at the edge of the canopy and in the open area at 10-, 30- and 50-cm soil depths. Mid-day twig water potential ( Ψ) and leaf conductance ( gs) were measured monthly. The sap flow of cypress trees was double that of pine. Pine seems to regulate its stomata and shows less response to rainfall compared to cypress. Soil water balance computations showed that evapotranspiration from the 60-cm soil depth of the areas without tree canopy cover was higher than that of areas with canopy cover, likely due to preferential flows caused by the tree canopy and roots.

Soil water is a crucial factor for the growth of vegetation and sustainable development in water-limited areas. After large-scale vegetation restoration on the Chinese Loess Plateau, understanding the relationship between vegetation and deep soil moisture has become a crucial focus in current research. In this study, we selected artificial forest ( Pinus tabulaeformis, Robinia pseudoacacia, and Platycladus orientalis), apple orchard, secondary forest and farmland as the research objects, and native grassland as the control, using soil drilling techniques, we systematically monitored the soil water content of 0-10 m soil layer over two hydrological years, and explore the effects of different vegetation types on soil water deficiency. The results showed that: (1) The deep soil water various significantly among different vegetation types, which indicating the depth of the influence of vegetation on soil water has reached 10 m. (2) The mean deficit size values of P. tabulaeformis (0.14), R. pseudoacacia (0.17), P. orientalis (0.07), apple orchard (0.15) and secondary forest (0.10) and farmland (0.27) were positive in 0–1 m, indicating that surface soil water had accumulated during more than half of the sampling periods. In the 2–10 m soil layer, the mean deficit size was negative in all vegetation types except in farmland, leading to soil desiccation. The deficit size was found to fluctuate with soil depth. (3) Soil water deficit degree was affected by a combination of soil properties and vegetation growth. Altitude, soil bulk density and canopy density had a significant impact on soil water deficit. Our results indicate that the current afforestation model could lead to the deficiency of deep soil water. Therefore, in planning future vegetation allocation and management, it is imperative to make reasonable vegetation structure according to the available local soil and water resources.
