Odonates (Odonata) as indicators of the natural potential of sand mine ponds (Central Europe): environmental drivers and implications for biodiversity conservation

Odonates (dragonflies and damselflies) are well-recognized indicators of freshwater ecosystems; therefore, they were used to describe the natural potential of man-made habitats, i.e. sand ponds, in terms of species, ecological patterns of the occurrence of both larval and adult a...

Integrating Ion Mobility-Resolved Tandem Mass Spectrometry and Microcrystal Electron Diffraction for Structural Elucidation

Abstract Determining the three-dimensional structures of small molecules in complex mixtures remains challenging as current approaches typically require physical isolation and quantities of material that are excessive for many components. Here we present a reciprocal structure-de...

Evolution mechanism of damage locations in drift region of SiC MOSFETs under heavy ion irradiation

This paper investigates the evolution mechanism of severe thermal damage locations in the drift region of the SiC MOSFETs under different applied drain voltages (VDS(irra)) during heavy ion irradiation using 587 MeV 36Kr ions. It is interesting to find from the post-irradiation b...

Green surveillance: the social implications of harnessing local communities for conservation law enforcement in Namibia

In response to the social injustice and counterproductivity attributed to militarised conservation, anti-poaching efforts increasingly focus on ‘inclusivity’ and surveillance. This shift can be explained with the emergence of ontopower, a new form of environmental power that focu...

Supine With Moderate Frog Leg Positioning Optimizes Femoral Vein Exposure and May Reduce Arterial Injury Risk During Femoral Venipuncture

The overlap between the femoral vein (FV) and femoral artery (FA) complicates FV cannulation. This study used ultrasonography to evaluate the combined effects of body position and passive knee bending on FV size and exposure. In 103 healthy participants, femoral vessels were imag...

C2 multi-agent factory: large-small model collaboration empowering a new command and control paradigm

Abstract Command and control (C2) is an agile crisis management architecture for highly uncertain emergencies, originating from military operations but now widely deployed in public safety emergency response, traffic and airspace management, industrial energy systems, urban gover...

Speed of Sound Measurements of n -Dodecane, 2,2,4,4,6,8,8-Heptamethylnonane, and Toluene

Abstract Speed of sound data measured using a dual-path pulse-echo instrument are reported for n-dodecane, 2,2,4,4,6,8,8-heptamethylnonane (isocetane), and toluene. These data are reported at temperatures ranging from 230 to 420 K and at pressures up to 49.7 MPa. The combined exp...

KEMATANGAN KARIER MAHASISWA TINGKAT AKHIR PROGRAM STUDI BIMBINGAN DAN KONSELING

Career maturity is an important aspect of students’ readiness to transition from higher education to the world of work. Final-year students in Guidance and Counseling programs are expected to possess adequate career maturity because they will enter professional roles that require...

Amino Acid Elicitation for Improved Hypocrellin A Biosynthesis in Shiraia bambusicola Under Elevated Fermentation Temperature

Hypocrellin A (HA) is a perylenequinone photosensitizer produced by Shiraia bambusicola during submerged fermentation, but its accumulation during submerged fermentation remains limited by low biosynthetic efficiency. Building on our previous finding that 32 °C increased HA accum...

Recurrent PDGFRB-Mutations in the Epithelioid Variant of Fibrous Papules

Fibrous papule (FP) is a common benign dermal mesenchymal lesion presenting as a solitary, dome-shaped papule mostly located on the nose. The morphologic spectrum is broad, and a number of variants have been described, including hypercellular, clear cell, pigmented, pleomorphic,...

Hybrid transformer and CNN for hyperspectral image classification with spectral band selection

Abstract Hyperspectral images (HSI) play a vital role in remote sensing applications such as surveillance and precision agriculture, yet they face challenges including limited labeled samples and class imbalance. This paper presents a new method for HSI classification by integrat...

The Unnoticed Freezes in the AI Era

In 2023, 18% of American adults said they had ever used ChatGPT. By early 2026, that number was 44%. AI adoption in the workplace has been even more remarkable. According to Microsoft's 2024 Work Trend Index, 75% of knowledge workers were already using AI at work, with nearly hal...

Root-Based Phytostabilization of Thorium and Uranium in Rare Earth Element-Rich Soils

The expansion of rare earth element (REE) mining has raised concerns about the environmental risks associated with radioactive elements, particularly thorium (Th) and uranium (U), which commonly occur alongside REE-bearing minerals. We investigated the uptake and distribution of...

Excitonic Physics in Emerging 2D Semiconductors: A First-Principles Many-Body Perspective from Photodetection to Solar Energy Conversion

Abstract Chemically and structurally diverse two-dimensional semiconductors exhibit a broad range of excitonic and optical phenomena that have direct implications for optoelectronic functionality. We examine these materials from a first-principles many-body perspective, emphasizi...

From the Conditions of Human Existence to Psychological Organisation: The Structural Derivation of the Relational Provision Model

This foundational paper develops the Relational Provision Model (RPM) as an axiomatic-deductive, conditions-based model of psychological organisation. Its point of departure consists of two axioms of human existence: lifelong provision dependence and voluntary provision as the in...

C-Pol: Point-Charge Perturbation Scheme for Mapping Tensor Moment Surfaces

Abstract Molecular polarizability tensors beyond the dipole–dipole level are key inputs to polarizable force fields, polarizable embedding, and machine-learned response models, yet routines to compute them exist in few quantum chemistry codes and are largely confined to atom-cent...

A phase 2, randomised, placebo-controlled study to evaluate once-daily oral Travelan for the prevention of Travellers’ diarrhoea

Abstract This study evaluated once-daily oral dosing of Travelan (IMM-124E), a bovine polyclonal antibody product, for prevention of Enterotoxigenic Escherichia coli (ETEC)-induced diarrhoea. In this randomised, double-blind, placebo-controlled trial using an ETEC-controlled huma...

The Voxel-Phase Universe

*The Voxel-Phase Universe* resolves the mathematical and physical singularities of continuous three-dimensional spacetime by introducing an error-correcting, discrete spatial lattice. Under Frobenius’s Theorem (1877) and Hurwitz’s Theorem (1898), continuous three-dimensional numb...

Revisiting thermorheological simplicity in crumb rubber modified bitumen using fractional Maxwell modelling

Abstract The linear viscoelastic behaviour of highly modified bitumen such as crumb rubber modified bitumen (CRMB) is commonly characterised using time-temperature superposition (TTSP), although its validity depends on the assumption of thermorheological simplicity. This assumpti...

Spatially Extensive Snapshot Sampling Reveals Regional Turnover and Complements Temporal Surveys of Drosophilidae in Southern Brazil

Sampling design strongly influences which components of biodiversity are recovered in regional inventories. We evaluated a spatially extensive snapshot survey of Drosophilidae assemblages in southern Brazil and compared it with temporally repeated datasets from the same broad reg...
