Study on the synthesis of salicylaldimine nickel catalysts and their catalytic performance in ethylene oligomerization

A series of salicylaldimine ligands with different electronic effects and their corresponding nickel complexes were synthesized and characterized by FT-IR, UV-vis,1H NMR, TG, and MS. The ethylene oligomerization performances of the nickel catalysts were evaluated in cyclohexane....

A Salivary Conglomerate with a Substantial Organic Component Mimicking a Mineral Sialolith in the Mandibular–Sublingual Gland Complex of a Dog

Solid lesions of the mandibular–sublingual salivary gland complex are rare in dogs. We report the case of an 11-year-old, 5 kg, intact female Maltese dog that presented with a non-painful, 2–3 cm left cervical swelling, soft at the surface and firm in depth. Fine-needle aspiratio...

Problems of code: ethnographic encounters with the Amazon Forest as a computational model

As environmental issues become increasingly datafied, computer code is becoming more important to the quotidian work of earth system scientists. Not only has code become central to their knowledge practices, it has become a way in which social relations travel through global know...

Associations between methodological quality and representation in clinical trials of systemic lupus erythematosus therapies

Background Randomized clinical trials support drug development and uptake of new therapies for systemic lupus erythematosus (SLE). However, challenges to conducting high-quality clinical trials have been noted, including underrepresentation of minoritized populations. Currently,...

Star Wars at Fifty

This symposium celebrates the 50th anniversary of Star Wars (1977) with nineteen short essays from scholars who discuss its meaning, impact, and legacy. The essays examine the migrations and manifestations of the Star Wars universe across media, including animation, video games,...

Risk of early stroke recurrence and procedural stroke or death in carotid near occlusion patients scheduled for carotid endarterectomy

Abstract Background Carotid near occlusion (NO) refers to distal internal carotid artery (ICA) narrowing caused by proximal carotid stenosis (CS). Stroke risk and optimal management of NO remain controversial. Our aim was to determine the prevalence of NO severities, rates of pre...

The effect of topical glaucoma therapy on the corneal subepithelial layer

Glaucoma is one of the most common causes of vision loss worldwide. In Russia, more than 1 million patients with glaucoma were registered in 2022, including more than 100 000 patients with newly diagnosed glaucoma. Detection of early-stage glaucoma has improved in Russia thanks t...

Phytochemical Profiling and Biological Activities of Stachys cataonica Bhattacharjee et Hub.-Mor. Extracts: An LC–MS/MS-Based Approach

The genus Stachys L. genus is in the Lamiaceae family; comprises many numerous medicinally important taxa traditionally used in Anatolia for nutritional and therapeutic purposes. Many Stachys taxa Stachys species have been employed in folk medicine for respiratory, gastrointestin...

A qualitative typology of teachers’ orientations toward artificial intelligence integration in Lebanese schools

Abstract Artificial intelligence (AI) is increasingly reshaping educational practices, requiring teachers to develop new competencies while navigating complex ethical considerations. This qualitative study explores the perceptions, practices, and orientations of 28 Lebanese schoo...

Risk factors for syphilis among newly admitted prisoners: A case–control study

Background Syphilis remains a major global public health concern in various groups, including people in prisons, where the burden is substantial. This study aimed to identify factors associated with syphilis infection among newly admitted prisoners in a province of Thailand. Meth...

Changes in intravenous pantoprazole utilization following two sequential interventions in a tertiary referral hospital

Objectives Intravenous (IV) pantoprazole is an effective proton pump inhibitor (PPI) with certain evidence-based indications for acid-related disorders. However, many studies demonstrated the considerable inappropriate administration of IV pantoprazole, resulting in adverse drug...

Identifying Groups Using Animal Patterns: A Quantitative Comparison of Feature Extraction Methods

Many animal species have unique patterns on their body that allow for individual identification, and these patterns often have a genetic basis. This individual-level pattern variation can be leveraged in ecological applications in a number of ways, such as facilitating the identi...

Moving-target-enclosing control of nonholonomic MASs with bearing-only measurements and collision avoidance

This paper focuses on a moving-target-enclosing control problem for nonholonomic multi-agent systems with bearing-only measurements and collision avoidance. Due to the lack of distance measurements, a bearing-only observer is designed first to estimate the complete relative posit...

From Newton to Hamilton to Penrose: Emergent Structure in One Discreet Scaler Field

A single real scalar field, defined as energy density on a 64³ cubic lattice and advanced by one second-order rule in a causal tick, grows a soliton. We read it from the stored arrays of the Vyaptic Scalar Field (VSF) engine: one deterministic run, all 140,259 states kept, a seve...

A traffic safety resilience assessment incorporating conflict risk: application and comparison on two open roads with lateral interferences

Lateral interferences on open roads cause conflicts and delays that dissipate at varying rates, implying that open roads have different risk-absorption capacities. This study develops a traffic safety resilience (TSR) framework combining crossing time-to-collision (CTTC) with tim...

Recovery Processes and Delayed Density-Dependent Regulation Reduce Long-Term Insect Damage in Alder Stands

Long-term monitoring data provide an opportunity to distinguish between the prevalence of herbivorous insects and the ecological consequences of their activity. Using observations collected in alder stands within the Polish ICP Forests network during 2013–2025, we investigated te...

Chance-Constrained Autonomous Spacecraft Formation Reconfiguration and Rendezvous with Passive Abort Safety

This paper addresses fuel-efficient maneuver planning under uncertainty for spacecraft relative motion in low-Earth orbits with passive safety using relative orbital elements (ROE) framework. We adopt a chance-constrained optimal control formulation that explicitly incorporates o...

Well-being in digital-free tourism: A mixed-methods rhythmanalysis

Tourism research has largely treated well-being as a motivation or outcome, neglecting how it unfolds in-situ and relying on self-report data. Through a mixed-methods rhythmanalysis, this study examines how well-being emerges and evolves in digital-free tourism. Following 23 part...

Investigating Pedestrian Safety Near Transit Bus Stops

This research examined how road and bus stop design and characteristics influence pedestrian safety, shaping both user perceptions and behaviors, and affecting crash outcomes near transit stops. A three-stage methodology integrated quantitative analysis with empirical field resea...

INVESTIGATE FUNGAL EFFECTORS AND THEIR CONTRIBUTION TO FUSARIUM OXYSPORUM VIRULENCE FROM THE GENOME EVOLUTION, TRANSCRIPTION REGULATION, AND PROTEIN FUNCTION PERSPECTIVES

The Fusarium oxysporum species complex (FOSC) comprises more than 100 host-specific fungal pathogens and ranked as the top ten most destructive fungal plant pathogens worldwide, causing severe diseases and substantial agricultural losses. Although FOSC members share a largely con...
