Bats have the ability to fly without eye application in the darkness. In this study, we aimed to characterize the functional and structural acclimations of the lenses of two common bats with a various lifestyle in the Egyptian environment: the insectivorous bat (IB) (Pipistrellus kuhlii) and Egyptian fruit bat (FB) (Rousettus aegyptiacus). From each species, seven lenses were extracted from adult eyes.

Article Synopsis
- - Eosinophilic pustular folliculitis (EPF) is a rare skin condition, often misdiagnosed, where lesions appear primarily on the upper limbs, face, and trunk, but can initially show up on palms and soles.
- - A male patient, misdiagnosed with eczema for ten years, experienced recurring skin issues and had a biopsy that confirmed EPF due to eosinophilic infiltrates in hair follicles.
- - Treatment with 75mg/day of oral indomethacin led to complete resolution of his skin lesions, with no recurrence noted after three months.
Bumps and Dents are Not Perceptually Opposite When Exploring With Lateral Force Cues.

March 2024
Virtual tactile bumps and dents are presented by controlling frictional forces on a surface tactile display, a flat touch screen with tactile feedback functions. This technology enables users to touch and feel three-dimensional objects. The resistive force against a sliding finger is increased and then decreased compared to a base level to present a bump.

September 2024
Skin-slip provides crucial cues about the interaction state and surface properties. Currently, most skin-slip devices focus on two-dimensional tactile slip display and have limitations when displaying surface properties like bumps and contours. In this article, a wearable fingertip device with a simple, effective, and low-cost design for three-dimensional skin-slip display is proposed.

We consider spatially localized spiking activity patterns, so-called bumps, in ensembles of bistable spiking oscillators. The bistability consists in the coexistence of self-sustained spiking dynamics and a quiescent steady-state regime. We show numerically that the processes of growth or contraction of such patterns can be controlled by varying the intensity of multiplicative noise.
