Customized Itinerant Frequency Combs by Cascaded Nonlinear Effects

open access: yesAdvanced Science, EarlyView.
A cascaded third‐order nonlinear system generates an itinerant frequency comb with the comb center frequency decoupled from the cavity resonance. This enables arbitrary spectral scaling, flexible spacing adjustments, and real‐time central‐frequency engineering, allowing comb splicing and subdivision. The resulting versatility and reconfigurability open

Investigation on the Impact of Memristive Device Variability on Uncoupled Memristive Cellular Nonlinear Networks

open access: yesAdvanced Electronic Materials, EarlyView.
Memristors, nanoscale devices that compute and store data in the same place, promise compact, energy‐efficient image‐processing hardware, yet no two devices behave exactly alike. Simulations based on real device measurements show that a 256‐cell memristive cellular nonlinear network (M‐CellNN) detects image edges perfectly despite this variability and ...

Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

open access: yesAI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

A Rare Form of Microcephalic Primordial Dwarfism due to NSMCE2 Deficiency (Seckel Syndrome Type 10): A Report of Macular Involvement

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Biallelic variants in NSMCE2 (MMS21), which encodes the SUMO E3 ligase subunit of the SMC5/6 chromatin‐maintenance complex, have recently been implicated in microcephalic primordial dwarfism (MPD), corresponding to Seckel syndrome type 10 (OMIM #617246).

Combined orthodontic-surgical approach in the treatment of impacted upper canines [PDF]

open access: yesStomatološki glasnik Srbije, 2019
Impacted tooth is the tooth that failed to reach occlusal level, with a growth of 2/3 of the root completed. Etiological factors of the impacted teeth are various, but the main reason is the lack of space for their eruption.

Impact of Fluorosis is on Teeth

open access: yes, 2022
Teeth are the most studied body tissues to examine the impact of fluoride to human health. There are a few possible mechanisms that have been proposed. It is generally believed that the hypo mineralization of affected enamel is mainly due to in-situ toxic effects of the fluoride on the ameloblasts in the enamel formation, and not caused by the general ...
