Review of key technologies and applications of snake-like robots for underground coal mine operations

Meitan kexue jishu
Driven by the urgent demand for intelligent development in coal mining, snake-like robots were considered as key equipment for addressing operational challenges in complex underground environments due to their bio-inspired mechanical structures and ...

Neuroanatomical and functional correlates in borderline personality disorder: A narrative review

Ibrain, Volume 11, Issue 1, Page 19-31, Spring 2025.
Borderline personality disorder (BPD) is considered a dysfunctional, stable, and pervasive alteration in personality functioning with the inability to adapt to the environment, mental rigidity, and ego‐syntonic, and like all personality disorders is a consistent pattern of inner experience and behavior that deviates markedly from the expectations of ...

Navigating Acceptability: A Think‐Aloud Study of Subjective and Contextual Factors in Radiographic Image Rejection

Journal of Medical Radiation Sciences, EarlyView.
This study investigated how radiographers assess radiographic image quality using the think‐aloud technique. It reveals that image quality assessment is shaped by both technical standards and subjective, contextual factors, including patient condition and interprofessional dynamics. This highlights the importance of balancing standardised criteria with

Computing forward statics from tendon-length in flexible-joint hyper-redundant manipulators

Hyper-redundant tendon-driven manipulators offer greater flexibility and compliance over traditional manipulators. A common way of controlling such manipulators relies on adjusting tendon lengths, which is an accessible control parameter.

The rise and fall of a volcanic plateau: Landscape evolution at the fringes of the former Patagonian Ice Sheet, Meseta Chile Chico, central Patagonian Andes

Journal of Quaternary Science, EarlyView.
ABSTRACT Understanding Earth‐surface processes along the fringes of large ice sheets is integral to deciphering cold‐region environmental variability and anticipating slope instability under climate change. We investigate the Meseta Chile Chico, a volcanic plateau in the central Patagonian Andes, located at the eastern margin of the former Patagonian ...

Inverse Kinematics of Discretely Actuated Hyper-Redundant Manipulators Using Workspace Densities

, 1996
Hyper-redundant manipulators present an alternative to conventional 6 DOF manipulators for inspection, space, and medical applications. The additional degrees of freedom facilitate obstacle avoidance and allow tasks to be performed even if some of the ...

Styrene and its natural analogues: accumulation and sustainable production methods

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

Hepatic Adenomas in Men: Diagnostic Considerations and Management in the Modern Era

Journal of Surgical Oncology, EarlyView.
ABSTRACT Hepatic adenomas (HAs) are rare benign liver tumors traditionally associated with young women, yet contemporary epidemiologic trends reveal increasing recognition among men. Historically, universal resection in males has been recommended because of a nearly tenfold increased risk of malignant transformation as reported by Farges et al.
