Emergent Spinning and Orbital Motion in Clustered Wind‐Assisted Flyers
Advanced Science, EarlyView.Inspired by natural snowflake geometries, paper‐cut flyers exhibit geometry‐defined spinning and orbital motions during cluster formation in a wind tunnel. Collective flights of multiple paperflakes reveal dynamic clustering, fragmentation, and continuously evolving spin behaviors.

Visual snow syndrome - a clinical and phenotypical description of 1100 cases [PDF]
, 2019 Objective: To validate the current criteria of visual snow and to describe its common phenotype using a substantial clinical database. Methods: We performed a web-based survey of patients with self-assessed visual snow (n = 1,104), with either the ...

Disrupted connectivity within visual, attentional and salience networks in the visual snow syndrome [PDF]
, 2021 Here we investigate brain functional connectivity in patients with visual snow syndrome (VSS). Our main objective was to understand more about the underlying pathophysiology of this neurological syndrome. Twenty-four patients with VSS and an equal number

Advanced Science, EarlyView.Drop‐location sensitivity remains a key barrier to practical droplet‐based electricity generators (DEGs). Here, a polydimethylsiloxane slippery covalently attached liquid (PDMS‐SCAL)‐coated interface promotes droplet sliding instead of splitting or bouncing, allowing stable electricity generation from randomly falling raindrops. The resulting PDMS‐SCAL‐

Architected Load Paths Enable Stiffening and Motion Programming in Soft Pneumatic Actuators
Advanced Science, EarlyView.A single MARS template introduces an architected reinforcement strategy for programmable soft pneumatic actuators through internal structural organization and selective beam removal. This monolithic architecture enables deformation reconfiguration from continuous bending to joint‐like articulation and torsional motion, allowing one compliant platform ...

Metamorphopsia in neurological practice
Неврология, нейропсихиатрия, психосоматика, 2019 Metamorphopsia is distortion of the visual perception of environmental objects (shape, sizes, orientation, color, and/or motion parameters), but without affecting their essential characteristics.

Visual Snow-Like Symptoms and Posterior Uveitis following COVID-19 Infection
Case Reports in Ophthalmological Medicine, 2021 Visual snow (VS) is a neurologic condition consisting of a constant positive visual disturbance described as “static” with diagnosis requiring exclusion of competing neurologic and ophthalmologic disorders.
