Describing the natural history of endemic and endangered species is useful for developing effective conservation plans. Two important pieces of natural history are the timing of reproduction and morphometrics. In this study, we estimate the reproductive season of Antioquia Brushfinch (Atlapetes blancae) based on a large database of observations and captures. We also provide the most extensive morphometric database of males, females, and juvenile individuals for this species. Taking advantage of ecological modeling techniques, we estimated that the reproductive season of A. blancae most likely spans from February through August with peak reproductive activity during May. The reproductive activity is highly correlated to day length (r=0.68 95% CI = 0.2 – 0.9; t=2.9, df=10, p = 0.01) and precipitation during the first rainy season of the year (r= 0.88 95% CI = 0.3 – 1; t=3.9, df=4, p=0.02). Furthermore, it is also highly correlated with the reproductive activity of many other species in the genus Atlapetes (r=0.81 95% CI = 0.4 – 0.9; t=4.4, df=10, p = 0.001). We also found that juveniles are smaller than adults and females are smaller than males providing evidence for both, age and sex size dimorphism. This study is the first attempt to provide important missing information about A. blancae that could help with understanding population viability. With this study, we now can focus conservation actions on periods of reproduction which are important bottlenecks of bird populations.

Objective Spontaneous vaginal births are often the presumed choice and represent 45% of UK births. However, information is inconsistently given about benefits and risks. This impacts decision-making and experience. A Core Information Set (CIS) is an agreed set of information points discussed prior to a decision. We aimed to develop a CIS for vaginal birth. Design Information points were identified from a literature search, patient information leaflets, interviews, and a survey. These informed a two-round Delphi survey, where stakeholders voted on the importance of items for inclusion. Items supported by >80% of participants were discussed by 28 parents and professionals at consensus meetings. The final CIS was populated with an engagement group ensuring accessibility. Setting The study took place in the UK, with participants recruited online. Population Pregnant and postnatal women, birth partners, healthcare professionals, medico-legal professionals and people working for interested/relevant organisations. Main outcome A CIS for vaginal birth. Results 77 information items were identified. In round 1 (631 participants) of the Delphi Survey, 84.5% were from the patient group and 15.5% from the professional group; in round 2 (228 participants), 74.3% were from the patient group and 25.7% from the professional group. 28 items met the criteria for consensus discussion. The final CIS includes 19 information points addressing: labour process, pain relief, labour complications, procedures or interventions during labour, experiences after birth, outcomes for the baby and environment during labour. Conclusions This CIS can be used to facilitate discussions and support informed decision-making about vaginal birth.

Background: Post-partum haemorrhage (PPH) is a common complication of labour. Objective: To assess the effectiveness of oxytocin in comparison to no treatment for the prevention of PPH. Selection criteria: Published and unpublished randomised controlled trials (RCTs) comparing systemic oxytocin to placebo or no intervention for the prevention of PPH were included. We did not apply language restrictions. Search Strategy: We identified RCTs from the Cochrane network meta-analysis on uterotonics for the prevention of PPH and updated the search via: Ovid MEDLINE, Embase via Ovid, Web of Science, CENTRAL, CINAHL Plus and clinicaltrials.gov. Data collection and analysis: An Individual participant data (IPD) meta-analysis. Main results: Of 14 eligible RCTs, four provided IPD (n=4,304; 51.7% received oxytocin and 48.4% received placebo or no intervention). Meta-analysis of IPD showed that oxytocin decreased the risk of PPH≥500 mL (aOR 0.59; 95% CI 0.46 to 0.74) and PPH≥1000 mL (aOR 0.51; 95%CI 0.32 to 0.80). Of ten RCTs that did not share data, seven met trustworthiness criteria while three did not. Trustworthy IPD and aggregate data from RCTs meeting trustworthiness criteria (n=6,003) showed that oxytocin significantly reduced the rate of PPH≥500 mL (aOR 0.53; 95%CI 0.45 to 0.62) and PPH≥1000 mL (aOR 0.59; 95%CI 0.48 to 0.71). Three RCTs not meeting trustworthiness criteria (n=1,027) reported a larger risk reduction of oxytocin for PPH≥500mL (aOR 0.37; 95%CI 0.03 to 4.03) and PPH≥1000mL (aOR 0.13; 95%CI 0.01 to 1.45). Conclusions : Prophylactic oxytocin reduces the risk of PPH≥500mL and PPH≥1000mL compared to no treatment. Studies not meeting trustworthiness criteria reported a larger effect, underlining the importance of integrity assessment in MA.

Objectives: To describe changes by time, and to analyse the current use of hormone therapy (HT) according age, geography, urbanisation, education, and occupational groups. Design: A historical descriptive study based on National Registry data. Setting: Denmark, January 2000 through September 2023 Population: All 1,703,162 female citizens 45-69 years old through the study period. Methods:. All figures were calculated as defined daily doses per 100 person-days. Outcomes: Use of different HT regimens and routes of administration. Results: Among females 45-69 years, use of systemic HT declined from 17% in 2000 to 3% in 2015 and onwards. Among users of combined regimens, oral administration accounted for 90% of the use until 2010. Since then, parenteral routes increased their share to 50% at end of study period. Systemic HT was most frequently used in the capital region, and more frequent in cities than in countryside, whereas local vaginal estrogen was evenly distributed according to urbanisation. In 2020-23 among females 50-59 years, systemic HT increased about 50% with increasing length of education. The percentage use was 4% in the general population, threefold higher (12%) among general practitioners, fivefold higher (20%) in spouses of male gynaecologists and nine-fold higher (35%) in female gynaecologists. Conclusion: Use of HT increases with urbanisation, with length of education, and is several folds higher among general practitioners, gynaecologists and in their spouses. Parenteral routes of HT have through last decade increased their share of HT.

Background: Global human migration has highlighted the need to provide culturally-appropriate maternity care, delivered in accordance with the recipient’s beliefs and practices. Objectives: This review aims to examine the impact of culture on access, utilisation, and care delivery of care for Muslim women during pregnancy, and postpartum, through the experiences of women, families, and maternity care-providers. Search Strategy: Six electronic databases were searched for published qualitative and mixed-methods studies, in English (01/January/2003-12/October/2023). Selection criteria: Studies undertaken in high-income countries reporting the experiences of either Muslim women accessing and utilising maternity services, or care-providers delivering those services. Data collection and analysis: Meta-ethnography was used to develop new concepts from included studies. Main results: Of 23,428 articles identified, 24 met inclusion criteria. Four themes were identified: ‘ Religious influences’, ‘Sociocultural interactions’, ‘Healthcare as a culture’, and ‘Disrupted communication’. Women’s negative experiences highlighted cultural insensitivity, providers’ unconscious bias, inflexible care models (and the conflict between expectations of services and those offered), and cultural stereotyping in addition to indifferent and uniform care. Care-providers’ experiences highlighted challenges with miscommunication and Muslim women’s reliance on information (and sometimes, misinformation) from their communities. Conclusions: Our findings highlight the challenges involved in delivering culturally-sensitive care to Muslim women; issues that extend beyond the confines of culture-specific awareness of religion and ethnicity, to the universal concept of personalisation. This is reflected in the theory, ‘ Recognise our differences, embrace our diversity, and care for me as an individual’.

COMMENTARY

Specific phenotype, comorbidities and unique CLA+ T-cell responses in atopic dermatitis patients with high serum LDHTo the Editor,Lactate dehydrogenase (LDH) is a reliable serum biomarker that correlates with disease severity in non-treated adult patients with atopic dermatitis (AD).1 However, the impact of high or low serum LDH levels on clinical manifestations and immune-mediated mechanisms in patients with AD has not been characterized. We stratified 47 non-treated moderate-to-severe adult AD subjects into LDHhigh (≥ 206 kU/L, n = 24) and LDHlow (< 206 kU/L, n = 23) based on the median levels of serum LDH (Figure 1A) and evaluated whether these two groups were clinically and functionally distinct.Our results showed that serum LDH levels were significantly higher in LDHhigh patients compared to control individuals, while similar levels were found in LDHlow and controls (Figure 1B). Clinically, LDHhigh individuals were younger, exhibited increased disease severity and eosinophil count in blood, as well as elevated house dust mite- (HDM), staphylococcal enterotoxin B (SEB)-specific and total IgE levels in plasma than the LDHlow subgroup (Figure 1C-H). No differences in gender nor pruritus intensity were observed between groups (data not shown). Consistent with previous reports, we observed a positive correlation between serum LDH levels and both EASI and eosinophilia.1,2 Nevertheless, our analysis extended beyond these findings by considering the influence of high or low levels of LDH and demonstrated that these correlations only occurred in LDHhigh and not LDHlow patients (Figure 1I,J). By contrast, serum LDH levels were indirectly correlated with age in the latter, rather than the former group (Figure 1K). Interestingly, we observed a significantly higher prevalence of allergic rhinitis and conjunctivitis, but not asthma nor food allergy, among LDHhigh patients compared to LDHlow(Figure 1L).Next, to assess the effector function of cutaneous immune responses in LDHhigh/low patients, we used a coculture previously stablished by our group,3 made of circulating skin-homing CLA+ or systemic CLA–memory T cells cultured with autologous lesional epidermal cells activated with either HDM extract or SEB. We compared the in vitro response to HDM between groups and found that only CLA+ memory T cells, rather than CLA–, produced significantly higher levels of IL-13, IL-5 and IL-9 in LDHhigh in contrast to LDHlow patients and controls (Figure 2). These results are consistent with the high percentage of AD patients with rhinitis and conjunctivitis, since type 2 cytokines contribute to the development of allergic comorbidities. Additionally, these findings also align with previous data from our group reporting high LDH levels in patients with IL-9 production.4 The amount of IL-4, IL-31, IL-22, IL-17A and IFN-γ produced by HDM-activated CLA+/Epi cocultures was similar among AD groups. Interestingly, no differences in cytokine production were found when using SEB to activate the cocultures in the same cohort of patients, except for CLA+T-cell-derived IL-31 levels (Figure S1).This is the first report showing that serum LDH levels distinguish patients with AD in terms of clinical features and in vitro T-cell responses. In conclusion, we consider that assessing serum LDH levels may be beneficial to stratify patients for therapeutic selection, given the complex heterogeneity of AD and the recently suggested capacity of LDH to predict treatment response in Asian populations.5,6WORD COUNT: 514

The green synthesis of nanoparticles using plant extracts has garnered significant attention as a reliable and sustainable method for producing functional nanomaterials. Among these, zinc oxide (ZnO) nanoparticles are extensively studied for their potential biological applications. In this study, ZnO nanoparticles were synthesized through a green synthesis approach using an aqueous extract of Musa acuminata leaves and zinc acetate as precursors. The resulting nanoparticles were characterized using Ultraviolet–Visible spectroscopy (UV–Vis), Fourier Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction analysis (XRD), Energy-Dispersive X-ray analysis (EDX), and Scanning Electron Microscopy (SEM). The UV–Vis spectra revealed characteristic absorption peaks around 350 nm, attributed to the nanoparticles’ large excitation binding energy at room temperature. FT-IR analyses confirmed the formation of zinc oxide chemical bonds, while XRD results indicated a hexagonal wurtzite crystal structure. SEM analysis showed that the nanoparticles had a nearly cuboid shape, and EDX analysis confirmed their high purity. The minimum inhibitory concentrations (MIC) of the synthesized ZnO nanoparticles were evaluated against Staphylococcus aureus and E. coli cultures. Cotton wound bandages impregnated with ZnO nanoparticles at concentrations near the calculated MIC demonstrated significant antibacterial activity in vitro. These antimicrobial bandages show potential for use in treating and protecting infection-prone wounds, such as diabetic or burn-related injuries.

Focused Ion Beam – Scanning Electron Microscopy (FIB-SEM) is a microscopy technique which can be used to investigate the quality and structural properties of industrial materials such as polyolefins. An understudied aspect and possible drawback of the technique could be the implantation of the impinging ions under the sample surface and damage to the molecular structure, hindering its use as a sample preparation tool for surface sensitive techniques. We systematically investigated the damaging effects of gallium liquid metal focused ion beam under grazing incident beam angle and various accelerating voltages on polyethylene. Changes in molecular structure and ion implantation depth were analyzed with Time-of-Flight Secondary Ion Mass Spectrometry depth profiling (ToF-SIMS) and optical profilometry. Our results show that the gallium ion beam causes significant damage to the polyolefin structure, which is especially observed as dehydrogenation of the molecular structure of the (sub)surface. These molecular products are concentrated in distinct sub-surface zones, where damage is coupled to the presence of implanted gallium from the FIB etching.

Key clinical message:While large segmental hemangiomas on the face are the hallmark of PHACE syndrome, the condition’s hidden threats lie in the often-overlooked abnormalities of the brain, aorta, and cervical arteries. These vascular anomalies, which are not detectable through a simple clinical examination, carry significant risks for morbidity. Early imaging studies are therefore critical.

The Canadian wildfires of 2023 highlight the severe threat to public health from smoke exposure. This study investigates the future distribution of wildfires and their smoke impacts under the SSP585 climate scenario. Utilizing the Canadian National Fire Database, we analyze historical wildfire ignition frequency and size distribution. We correlate wildfire with vapor pressure deficit (VPD), using historical and projected VPD data derived from CMIP6. We simulate about 1 million synthetic events, each with calculated smoke impacts. Our preliminary findings indicate a significant increase (35%-78%) in public exposure to wildfire smoke (PM > 50 μg/m³), with Eastern Canada being particularly affected as well as a few major cities in the US. This intensifies the public health threat from future wildfire smoke, necessitating urgent mitigation and adaptation strategies.

Introduction Atrial fibrillation (AF) is a common arrhythmia with significant health implications. Identifying modifiable lifestyle triggers is important in mitigating recurrence and improving patient outcomes. A subset of AF patients has reported cold drinks or foods as triggers, a phenomenon termed “Cold Drink Heart” (CDH). Literature on CDH is scarce and primarily limited to case studies. We sought to characterize patient experiences with CDH and assess the effectiveness of cold trigger avoidance in reducing AF recurrence among affected patients. Methods and Results This was a mixed methods study employing a patient survey enhanced by chart review among patients who self-reported CDH. Participants were recruited during emergency department visits for AF or by contacting the principal investigator directly. The survey addressed demographics and clinical features. We compared those with CDH only and those with both CDH and non-CDH AF episodes. The cohort included 101 respondents (75% male). Median age of CDH onset was 44.5 years. Most respondents (96.8%) reported that cold ingestion did not consistently trigger AF. Rapid onset after ingestion was common, and many reported an association with recent physical exertion. Avoidance of cold ingestion was effective in reducing or eliminating AF episodes in 86.4% of cases, with greater success in CDH-only patients (100.0%). Physician awareness was low, with 52.4% of respondents reporting dismissive attitudes from one or more healthcare providers. Conclusion CDH is poorly understood and has significant implications for AF prevention. Avoidance strategies may be highly effective, especially for CDH-only patients. Further research is needed to validate these findings and increase provider awareness.

Mafic magmatic enclaves, common to many silicic magmatic systems, are often interpreted as evidence for recharge of shallowly stored magma with basaltic magma from depth. They are linked to the triggering of volcanic eruptions and the necessary thermal input to sustain shallow magma systems. What happens to mafic-magmatic enclaves after their formation remains mostly unknown. They may settle due to buoyancy, be part of erupting magma, or stay in the mobile part of the magma storage region. Textures such as glassy rims resulting from rapid cooling and their high crystallinity are evidence for their rheological response to flow and mixing as a solid. The solid boundary surface between the two magmas can be disrupted by convective motion in the host magma and over time, the entire magma body may undergo hybridization through chemical diffusion and mechanical disintegration.

This study delves into the present-day seismotectonic conditions beneath the intracontinental High Atlas Mountains, Morocco, with a focus on the region of the significant Al Haouz earthquake on September 8, 2023. the analysis encompasses over twenty moderate seismic events recorded since 2009, utilizing a database of high-resolution seismic recordings (magnitudes ranging from 3.5 to 7) collected by networks established between 2008 and 2024. The primary objective is to refine preliminary earthquake relocation, initially based on P-wave arrival times, by incorporating residual travel-time data from each hypocenter pair to seismic stations. Results from these methods are nearly identical, with the double-difference method yielding the most accurate outcomes. Seismic activity in the region, with depths not exceeding 30 km, appears Skin-Deep, consistent with observations from the latesst Al Haouz earthquake, occurring at a depth of 31 km. The present-day tectonic regimes along the High Atlas system (western and central parts) are determined through inversion of regional seismic moment and tectonic stress tensors. Focal mechanism solutions for well-located earthquakes are calculated using P-wave first motion polarities and regional moment tensor inversion. Subsequently, tectonic stress tensor properties are derived through inversion of focal mechanism parameters. Most seismic events analyzed exhibit focal mechanisms characterized by pure reverse faulting or reverse faulting with a strike-slip faulting component. The orientation of P, B & T axes is 16/189, 39/036, and 08/104 respectively. Estimated stress tensor parameters suggest σ1 axes trend N-S in the Western High Atlas and NW-SE to NNW-NNE in the Central High Atlas. These tectonic regimes align well with GPS velocities and neotectonic data, elucidating the tectonic deformation process observed in the High Atlas, particularly in concordance with characteristics of the Al Haouz earthquake beneath the Western High Atlas area. Keywords: Double Difference Location, First Motion Polarity, Focal Mechanism, Tectonic Stress, Inversion, Western High Atlas, Central High Atlas, Morocco.

This article develops existence results for non-linear partial differential equations in superconductivity. Specifically for the parabolic model, the method of proof comprises a variational approach for establishing a concerning solution existence at each instant of time, related to a model discretized in time. Moreover, as a novelty, we have modeled the Ginzburg-Landau system in superconductivity as a two phase one, with a wave function for a super-conducting phase and another for a normal phase.

This study used environmental DNA(eDNA) metabarcoding to monitor fish communities at 14 sites along the upper Yangtze River across four seasons, aiming to understand seasonal variations in community structure. This study reflects on the current status of fish community structure in the region by leveraging an analytical discussion on the composition of fish species and functional groups, the application of 16 multidimensional diversity indices, and the relationships between fish communities and environmental variables. A total of 120 fish species were detected. The communities predominantly consisted of species that produce sticky eggs, are sedentary, and have omnivorous diets. However, the relative abundance of species producing drifting eggs, migratory, and carnivore fish groups was higher in autumn and winter compared to spring and summer. Except for the functional evenness index(FEve), all other functional diversity indices, as well as α diversity, taxonomic diversity, and phylogenetic diversity indices, were higher in spring and summer compared to autumn and winter. This suggests that fish diversity is greater in spring and summer; however, ecological niche overlap is more pronounced during these seasons. Multiple diversity indices demonstrated a high degree of correlation among them. This study provides practical experience for fish monitoring based on eDNA metabarcoding technology.

A 14-year-old female miniature horse presented with mild colic signs. The owner reported a history of colic secondary to presumed gastric ulceration, treated with flunixin meglumine and omeprazole. On admission, physical examination demonstrated a normal TPR with reduced intestinal motility. Abdominal ultrasonography revealed distended, thickened small intestine loops (14 mm) in the right paralumbar fossa (Fig. [1](#fig-cap-0001)). Radiographs confirmed multiple enteroliths and sand accumulation. Routine bloodwork indicated dehydration (PCV 54%) and mild hyperlactatemia (3.79 mmol/L). As a results of abdominal ultrasound findings, an exploratory celiotomy was performed, revealing a strangulation obstruction of the distal jejunum and ileum due to epiploic foramen entrapment, along with multiple enteroliths. Approximately two feet of nonviable small intestine were resected, and a jejunocecostomy was created. Two enterotomies were performed to remove enteroliths and sand. Postoperatively, the miniature horse received IV fluids with lidocaine, NSAIDs, antibiotics, and omeprazole. By day seven, the miniature horse resumed a normal diet and was discharged on day ten. At an 18-month follow-up, the miniature horse remained healthy and fully active. This case represents the first reported instance of epiploic foramen entrapment in a miniature horse.

This study investigated forest edge areas adjacent to a residential road in a hilly area of Nagano Prefecture, Japan, to examine the impact of Cervus nippon (hereafter referred to as “deer”) movements on physical erosion and changes in infiltration capacity of forest soils. The survey area included the edges of cypress and larch forests bordering a residential road west of the Mochizuki Highland Ranch in Mochizuki-machi, Saku City, Nagano Prefecture. Soil erosion was assessed by measuring the height and direction of exposed roots at multiple points. Analysis of root system exposure height ( Rh) revealed higher values in the larch forest than in the Japanese cypress forest. Furthermore, the polar coordinate distribution of exposed roots indicated predominant exposure in the steepest slope direction, with some deviations, suggesting that slope angle influences deer movement patterns. Comparisons of cumulative infiltration capacity showed lower values in the cypress forest compared to the larch forest. Soil with clear deer hoof prints exhibited lower infiltration capacity in both areas. The unsaturated hydraulic conductivity ( K) for disturbed soil along the deer migration route was approximately half that for natural soil, and in soil with clear deer hoof prints, it decreased to about 1/10 that for natural soil. These findings demonstrate that deer traffic significantly reduces soil infiltration capacity. The results indicated that in forested areas with high levels of deer traffic, K may decrease to 1/2 to 1/10 of normal levels, highlighting the substantial impact of deer activity on forest soil properties.

Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS) is characterized by sudden neuropsychiatric symptoms, such as obsessive-compulsive disorder (OCD) and tics, following streptococcal infections. Among the treatments explored, corticosteroids like prednisone have been used for their immunosuppressive effects to reduce inflammation and autoimmune responses. However, the comparison between corticosteroids and other steroid treatments in PANDAS management is still a subject of clinical debate. Corticosteroids tend to provide short-term relief in managing acute flares but are often associated with symptom recurrence post-treatment, making them a less favorable long-term solution. This review evaluates the effectiveness of corticosteroids versus regular steroids, analyzing their role in reducing symptom severity, flare duration, and relapse rates in PANDAS patients. While corticosteroids are widely used for their ability to control inflammation during acute episodes, other steroids may offer varied efficacy and side-effect profiles. The need for further research remains crucial to establishing clearer, long-term treatment guidelines.

A current challenge in ecology is to understand and predict how species abundance and diversity change with rapidly shifting temperature regimes. Temperature affects the local and regional dynamics underlying community structure in predictable ways, but whether this translates to predictable community-level outcomes with warming remains an open question. We address this gap with a framework that draws from metabolic theory to model temperature-dependent metacommunity processes—density-independent population growth, density-dependent biotic interactions, and dispersal—and their effects on diversity patterns. We simulated metacommunity dynamics to show how species richness, relative abundance, and beta diversity respond to up to 10°C warming, exploring effects of variation in thermal response curves for different metacommunity processes. We demonstrate how factors such as thermal safety margins and thermal asymmetries among metacommunity processes mediate the magnitude of this change. Our framework highlights the importance of incorporating dispersal and species interactions, as well as accurately identifying their thermal response curves, in predictive models of diversity change.

There has been an increasing interest in using GNNs to build recommender systems as they enable the representation of complex relationships between users and items through knowledge graph embeddings. However, most of the knowledge-graph based systems focus only on ratings or reviews to build relationships. This prevents comprehensive understanding of structural and positional information within graph data as well as user preferences that can change in time, as well. In order to address these issues, this paper aims to propose an advanced end-to-end Graph Neural Network architecture that significantly enhances recommendation system capabilities through the integration of state-of-the-art embedding techniques, knowledge graph frameworks, and transfer learning strategies. Incorporating positional encoding and topological feature extraction, the proposed model captures intricate user-item relationships and offers a robust representation that surpasses current approaches. A pre-trained encoder facilitates knowledge transfer, effectively bridging domain gaps and amplifying the prediction accuracy. Comprehensive evaluations against established baseline models reveal that our architecture has demonstrated enhanced accuracy, precision, and overall robustness. These results highlight the efficacy of combining knowledge graphs, sophisticated embedding strategies, and cross-domain transfer learning in building next-generation recommender systems, providing valuable insights for future advancements in the field.

Recent work on time-series models has leveraged self-supervised training to learn meaningful features and patterns in order to improve performance on downstream tasks and generalize to unseen modalities. While these pretraining methods have shown great promise in one-to-many scenarios, where a model is pre-trained on one dataset and fine-tuned on a downstream dataset, they have struggled to generalize to new datasets when more datasets are added during pre-training. This is a fundamental challenge in building foundation models for time-series data, as it limits the ability to develop models that can learn from a large variety of diverse datasets available. To address this challenge, we present a new pre-training paradigm for time-series data called ADAPT, which can efficiently align the physical properties of data in the time-series domain, enabling mixed-batch pre-training despite the extreme discrepancies in the input sizes and channel dimensions of pre-training data. We trained on 162 time-series classification datasets and set new state-of-the-art performance for classification benchmarks. We successfully train a model within the time-series domain on a wide range of datasets simultaneously, which is a major building block for building generalist foundation models in time-series domains.
