Ulnar nerve lesions at the elbow can usually be recognized by a characteristic combination of physical signs. In the hand, there is wasting and weakness of ulnar-innervated muscles with or without sensory loss of appropriate distribution; in the forearm there is often weakness of the ulnarinnervated portion of the flexor digitorum profundus and sometimes of the flexor carpi ulnaris. Further con...

Polyoxometalates (POMs) equipped with vanadium centers offer outstanding opportunities for the development of switchable molecularly functionalized surfaces non-binary, beyond-CMOS memory chips. In article number 2200461, Maria Glöß, Silvia Karthäuser, Kirill Yu. Monakhov, and co-workers report a room-temperature, multistate resistive switch based on V3-substituted Wells-Dawson-type POM structu...

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with symptom onset prior to age 3. Although there is great variability in symptom severity and intellectual functioning, ASD is defined by a triad of symptoms, including impairments in social functioning and interaction, impairments in communication, and restricted, repetitive, and stereotyped behaviors, interests, and activities (...

Quantifying the flows generated by the pulsations of jellyfish bells is crucial for understanding the mechanics and efficiency of their swimming and feeding. Recent experimental and theoretical work has focused on the dynamics of vortices in the wakes of swimming jellyfish with relatively simple oral arms and tentacles. The significance of bell pulsations for generating feeding currents through...

The development of a rowing jellyfish biomimetic robot termed as "Robojelly", has led to the discovery of a passive flexible flap located between the flexion point and bell margin on the Aurelia aurita. A comparative analysis of biomimetic robots showed that the presence of a passive flexible flap results in a significant increase in the swimming performance. In this work we further investigate...
