Magnetic resonance imaging findings in adnexial torsion [PDF]

Einstein (São Paulo), 2010
Adnexial torsion is an unusual event, but a major cause of abdominal pain in women. It is often associated with ovarian tumor or cyst, but can occur in normal ovaries, especially in children.

Infarcted accessory liver lobe in a pediatric patient: A case report

Journal of Pediatric Surgery Case Reports, 2023
Introduction: Accessory liver lobe (ALL) is a rare abnormality of the liver that occurs during the third week of pregnancy due to the division of the hepatic bud and distortion of the endodermal caudal foregut. ALLs are typically asymptomatic.

Deformation and Degradation in 18650 Li‐Ion Cells Under Freeze‐Thaw Cycling

Advanced Functional Materials, EarlyView.
This study investigates the impact of freezethaw degradation of 18650 cells via combined electrochemical and x‐ray imaging studies. High‐resolution synchrotron X‐ray tomography reveals deformation of the jelly‐roll structure and delamination of electrode active materials in cells cycled at 1C and 4C. These structural changes are quantitatively assessed

MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

Advanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.

Compression‐Tension‐Asymmetry and Stiffness Nonlinearity of Collagen‐Matrigel Composite Hydrogels

Advanced Healthcare Materials, EarlyView.
Self‐assembled collagen hydrogel matrices are widely used in tissue engineering applications. These matrices stiffen and contract laterally under tension due to fiber alignment and soften and collapse under compression due to fiber buckling. It is demonstrated that filler materials, such as Matrigel, linearize the mechanical behavior of collagen ...
