Advancing Severe Plastic Deformation for Tubular Samples: Systematic Review and Machine Learning Optimization

open access: yesMetalMat, EarlyView.
This review highlights recent advancements in Severe Plastic Deformation (SPD) techniques tailored for tubular samples. The mechanisms of processing are critically discussed with emphasis on microstructural control and the governing process parameters that enable refinement to ultrafine‐ and nano‐grained structures. Comparative insights into equivalent

Exploring the Properties of Photosphere and Emission Lines for Tidal Disruption Events Based on the Global Solution of Slim Disk and Winds

open access: yesThe Astrophysical Journal
The theoretical debris supply rate from a tidal disruption of stars can exceed about 100 times of Eddington accretion rate for a 10 ^6−7 M _⊙ supermassive black hole.

Molecular phylogeny and morphological characterization revealed Candolleomyces mianwaliensis Psathyrellaceae, Agaricales, a new species from Punjab, Pakistan

open access: yesNordic Journal of Botany, EarlyView.
Candolleomyces mianwaliensis is described as a new species from Mianwali District, Punjab Pakistan. The species is characterized by spherical to plane pileus bearing pale orange irregular scales scattered over smooth dark orange surface when young, turning into off‐white scales over brown to dark brown surface towards maturity, and a double membranous ...

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study

open access: yesPolymer Composites, EarlyView.
Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts

Cryostratigraphy of Rhythmic Segregated Ice in Colluvium and Implications for Permafrost Slope Stability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Vegetal residue‐based formulation of Trichoderma ossianense, a new indigenous vineyard species adapted to alkaline pH with potential biocontrol ability against Black‐foot disease pathogens

open access: yesPest Management Science, EarlyView.
The study identifies Trichoderma ossianense, was can be isolated from grapevine roots, is capable of growing at alkaline pH and controls black‐foot pathogens, highlighting the vegetal residue‐based formulations that preserve its viability. Abstract BACKGROUND Fungi of the Trichoderma genus are used in vineyards as biological control agents mainly ...

JWST-TST High Contrast: JWST/NIRCam Observations of the Young Giant Planet β Pic b

open access: yesThe Astronomical Journal
We present the first JWST/NIRCam observations of the directly imaged gas giant exoplanet β Pic b. Observations in six filters using NIRCam's round coronagraphic masks provide a high-signal-to-noise-ratio detection of β Pic b and the archetypal debris ...
