Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

Advanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

Immunological and periodontal benefits of prebiotic polydextrose in rats with induced periodontitis

Journal of Periodontology, EarlyView.
Abstract Background Prebiotic therapy is a promising approach for managing periodontitis due to its potential benefits in modulating the microbiome and the immune response. This study aimed to evaluate the effects of the prebiotic (PREB) polydextrose (PDX) on the development of experimental periodontitis (EP) in rats.

Dasatinib and quercetin prevent alveolar bone loss in aged mice

Journal of Periodontology, EarlyView.
Abstract Background Recent findings have associated alveolar bone loss (ABL) with the presence of senescent cells. Aging and the accumulation of senescent cells are associated with a pro‐inflammatory environment which may exacerbate tissue damage.

Receiver multiuser diversity aided multi-stage minimum mean-square error detection for heavily loaded DS-CDMA and SDMA systems [PDF]

, 2010
By investigating the conditions required for successive interference cancellation multiuser detectors (SIC-MUD) to achieve near-optimum BER performance, we propose and investigate a so-called receiver multiuser diversity aided multi-stage minimum mean ...

Antimicrobial Photodynamic Therapy Associated With Systemic Treatment in Osteoradionecrosis: An In Vivo Study

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objective To evaluate the effects of antimicrobial photodynamic therapy (aPDT), systemic pharmacological therapy, and their combination on irradiated mandibular post‐extraction bone repair relevant to osteoradionecrosis (ORN) development in a rat model. Methods Twenty‐six male Wistar rats were initially randomized into five experimental groups:

Capacity and Error Performance of Reduced-Rank Transmitter Multiuser Preprocessing Based on Minimum Power Distortionless Response

, 2008
In this contribution we first derive a transmitter multiuser preprocessing (TMP) scheme for a general multiuser multiple-input-multiple-output (MIMO) system based on the minimum power distortionless response (MPDR) criterion, which minimizes the power in

Performance of the Space-Time Block Coded DS-CDMA Uplink Employing Soft-Output ACO-Aided Multiuser Space-Time Detection and Iterative Decoding [PDF]

, 2010
In this treatise we propose a three-stage twin-transmit-antenna assisted MultiUser (MU) Direct Sequence Code-Division Multiple Access (DS-CDMA) system employing both a Unitary Rate Code (URC) and a Recursive Systematic Code (RSC) to carry out iterative ...

Assessing Clinical Competence of Postgraduate Dental Specialty Trainees: A Scoping Review

European Journal of Dental Education, EarlyView.
ABSTRACT Background Assessment is essential to ensure that trainees meet competency standards in delivering patient care. However, a comprehensive summary of the literature on clinical assessment in postgraduate dental education is largely absent. Filling this gap is essential for developing effective assessment processes to help support competency ...
