SAR Ship Detection via Knowledge Transfer: From Optical Image
Pubblicazione 2025-01-01TestoKnowledge transfer technique was widely studied in target detection. Yet most of the preceding works were devoted to the transfer between the homologous domain. They were not effective to the knowledge transfer from optical image and synthetic aperture radar (SAR) data. To solve the problem, a new S...

The diffusion characteristics of Fe-Ti during shear-extrusion solid-state bonding and the influence of the level of deformation
Pubblicazione 2025-09-01TestoThis study investigates the applicability of shear-extrusion bonding (SEB) for joining pure iron (DT4a) and pure titanium (TA2) dissimilar metals at 950 °C across varying deformation levels from 112.9 % to 144.4 %. Microstructural analysis confirmed effective metallurgical bonding achieved above 112...

Effects of dietary supplementation of grape seed extract in comparison with excessive level of vitamin E on growth performance and antioxidant function of broilers
Pubblicazione 2024-12-01TestoThe present study was carried out to evaluate the effects of dietary vitamin E (VE) or grape seed extract (GSE) on the growth performance and antioxidant function of broilers. Two hundred sixteen broiler chicks were randomly assigned to 3 diets: diet supplemented with oxidized rice bran oil (CN grou...

Hypertension mediates the association between weight-adjusted waist index and new onset stroke risk in middle-aged and older Chinese adults: evidence from the CHARLS study
Pubblicazione 2025-07-01TestoBackgroundThe weight-adjusted waist index (WWI) serves as a novel body metric for evaluating abdominal adiposity. However, the association between WWI and stroke risk across varying blood pressure statuses remains poorly understood.MethodsThis study included 12,580 individuals aged 45 and above with...

Study on the Evolution of Overlying Strata Fractures and Gas Control Technology of High Gas-Drainage Roadways Under Gob-Side Entry Retaining with Roadside Filling
Pubblicazione 2025-07-01TestoIn order to examine the fracture development law of overlying strata in goafs and to reasonably lay out a high gas-drainage roadway under gob-side entry retaining with roadside filling, the 91–105 working face of the Wangzhuang Coal Mine was selected as the engineering case study. The failure laws a...

Revisiting the model for austenite grain size of M50 steel coupled with the carbide dissolution behavior
Pubblicazione 2025-07-01TestoThis study investigates the effects of time, temperature, and granular M2C carbides on the evolution of the average grain size of M50 steel. Based on classical theoretical models, it develops a predictive model for the average austenite grain size distribution. The research encompasses a temperature...

Tailoring heat-resistant phases with strengthening effects by compound additions of zirconium, yttrium and silicon in dilute Al-Sc-(Zr)-(Y)-(Si) alloys
Pubblicazione 2025-07-01TestoHeat resistance aluminum alloys serving within 300–400 °C temperature range are prominently required due to lightweight design and extreme serve condition in aerospace and military fields. Dispersoid particles precipitated in Al–Sc system alloys possess preferential thermal stability, however, unsat...
