Sampling, Mobility, and Anchoring in Small‐Body Sampling Robots: A Comprehensive Review

SmartBot, EarlyView.
Small‐body sampling robots are exploration systems that perform contact, sampling, and stable operations on microgravity bodies such as asteroids and comets. The authors review representative robot architectures and key technologies, focusing on the mechanisms, evolution, and coupling of sampling, mobility, and anchoring.

Critical shear crack shapes in slender reinforced concrete beams with and without shear reinforcement

Structural Concrete, EarlyView.
Abstract The accurate prediction of the shear capacity of reinforced concrete underpins the efficient and safe design of concrete buildings and infrastructure. Disagreement remains about shear mechanisms and the modeling of shear resistance. For slender beams without shear reinforcement, critical shear crack (CSC) models have attracted interest.

Processing Stabilization of Polyolefin Recyclates Using Alditols in Combination With α‐Tocopherol: A Sustainable Alternative to Phosphites

Journal of Vinyl and Additive Technology, EarlyView.
A novel bio‐based stabilizer system significantly improves the quality of polyolefin recyclates during multiple recycling cycles. ABSTRACT This study introduces a novel bio‐based stabilizer system for polyolefin recyclates that combines alditols with small amounts of α‐tocopherol as a sustainable alternative to conventional phosphite additives.

Managing micronutrients in metabolic and bariatric surgery: A mixed methods study of Australian dietitians' practice and perspectives

Nutrition &Dietetics, EarlyView.
Abstract Aims Dietitians play key roles in the care of patients undergoing metabolic and bariatric surgery, including micronutrient management. This study aimed to explore Australian dietitians' practices and perspectives on managing micronutrients in bariatric surgery.

Three Ventricular Assist Devices (True TriVAD) as Bridge to Durable Biventricular Support (BiVAD) in LVAD Patient With Severe Aortic Regurgitation

Artificial Organs, EarlyView.
An LVAD patient with severe aortic regurgitation (AR) developed right heart failure and multi‐organ dysfunction (MOD). tRVAD support caused LV overload and pulmonary edema. Impella 5.5 implantation successfully unloaded the LV and stabilized the patient, enabling durable RVAD implantation with surgical aortic valve replacement.
