Pilonidal Sinus Over Nasal Dorsum: Incidental Finding

open access: yesNational Board of Examinations Journal of Medical Sciences
Pilonidal refers to a collection of hair. The pilonidal sinus is a subcutaneous track containing hairs or their microscopic fragments. The sinus penetrates into the subcutaneous layers as a bulbous diverticulum with or without branching side channels ...

Exfoliated‐MoS2 Gradual Resistive Switching Devices as Artificial Synapses

open access: yesAdvanced Electronic Materials, EarlyView.
A vertical memristor based on untreated, exfoliated MoS2 is presented, revealing gradual resistive switching governed by Schottky barrier modulation at the MoS2/metal interface from the trapping/detrapping of charges. Furthermore, the device emulates synaptic‐like plasticity functions, including: potentiation, depression, and spike‐amplitude‐dependent ...

Millisecond‐Scale Relaxation in Metastable HZO Ferroelectric Capacitors for Bio‐Inspired Temporal Computing

open access: yesAdvanced Electronic Materials, EarlyView.
Through the introduction of a niobium oxide layer into a hafnia ferroelectric capacitor stack, we build a memory device with a strong imprint effect. This imprint leads to a millisecond retention loss that can be tuned by the programming conditions that can be utilized as a scalable, analog hardware time constant for bio‐inspired temporal computing ...

A Novel Parameter Estimation Method for Pneumatic Soft Hand Control Applying Logarithmic Decrement for Pseudo‐Rigid Body Modeling

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
In this research, a paradigm of parameter estimation method for pneumatic soft hand control is proposed. The method includes the following: 1) sampling harmonic damping waves, 2) applying pseudo‐rigid body modeling and the logarithmic decrement method, and 3) deriving position and force control.

Adaptive Collision Sensitivity for Efficient and Safe Human–Robot Collaboration

open access: yesAdvanced Intelligent Systems, EarlyView.
An adaptive collision‐sensitivity framework uses each robot link's effective mass to estimate contact forces online and decide when collaborative robots should stop or continue. Tested on simulated and real UR10e and simulated KUKA arms, it maintains conservative force estimates while reducing unnecessary stops and increasing task productivity. What is

Over-rotated Rieger flap for a large lateral nasal tip defect reconstruction

open access: yesDermatology Reports
A 65-year-old man presented with a Melanoma in situ of the nasal tip. Complete excision was achieved after 2 “Slow Mohs” stages, resulting in a circular 2.7 X 2.4 cm defect involving the right lateral nasal tip, dorsum and sidewall and extending to the ...
