A Fourth-Order Block-Grid Method for Solving Laplace's Equation on a Staircase Polygon with Boundary Functions in

open access: yesAbstract and Applied Analysis, 2013
The integral representations of the solution around the vertices of the interior reentered angles (on the “singular” parts) are approximated by the composite midpoint rule when the boundary functions are from These approximations are connected with the ...

Heat Transfer Enhancement Characteristics of Pin‐Fin Liquid Cooling Plate for Pouch Lithium‐Ion Battery

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Addressing issues such as low heat transfer intensity, high system power consumption, and poor temperature uniformity in liquid cooling plates for lithium‐ion batteries (LIBs) in electric vehicles (EVs), a pin‐fin liquid cooling plate was designed to enhance comprehensive heat transfer performance.

Study on the Fragmentation Characteristics and Dust Generation Mechanism of Coal Cutting by Pick

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT During underground excavation, coal dust generation threatens miners' health and damages ecosystems. Its generation is directly influenced by cutting pick performance and inherent coal properties. This study investigates the effects of coal properties and cutting parameters on coal fragmentation characteristics from a mesoscopic perspective ...

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint

open access: yesThe Anatomical Record, EarlyView.
Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

open access: yesThe Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...
