Enhanced Diagnostic Accuracy for Dental Caries and Anomalies in Panoramic Radiographs Using a Custom Deep Learning Model.

Background  Dental caries is one of the most prevalent conditions in dentistry worldwide. Early identification and classification of dental caries are essential for effective prevention and treatment. Panoramic dental radiographs are commonly used to screen for overall oral health, including dental caries and tooth anomalies.

Modeling nonlinear fractional-order subdiffusive dynamics in nuclear reactor with artificial neural networks.

This paper presents the development and analysis of artificial neural network (ANN) models for the nonlinear fractional-order (FO) point reactor kinetics model, FO Nordheim-Fuchs model, inverse FO point reactor kinetics model and FO constant delayed neutron production rate approximation model. These models represent the dynamics of a nuclear reactor with neutron transport modeled as subdiffusion. These FO models are nonlinear in nature, are comprised of a system of coupled fractional differential equations and integral equations, and are considered to be difficult for solving both analytically and numerically.

Role of Conjunctival Ultraviolet Autofluorescence in Ocular Surface Squamous Neoplasia.

Objective: To evaluate the adjunctive role of conjunctival autofluorescence in the management of ocular surface squamous neoplasia (OSSN).

Materials And Methods: Seventeen patients with clinically diagnosed OSSN were included. Morphological characteristics, type of OSSN, and autofluorescence photographs of the lesion were captured.

Perceived difficulties and complications in learners of phacoemulsification: A principal component analysis model.

Purpose: To evaluate the difficulty perceived of each step of phacoemulsification and analyze the factors affecting them.

Methods: Overall, 12 trainee residents were allotted 10 cases of phacoemulsification of eyes with senile cataract, under a single observer, and the steps of each surgery were rated from very easy to very difficult with a questionnaire. The completion rates of steps and complications of each surgery were noted.

Pythium Keratitis Leading to Fatal Cavernous Sinus Thrombophlebitis.

Purpose: To report a case of Pythium insidiosum keratitis leading to fatal cavernous sinus thrombophlebitis.

Methods: Case report.

Results: A 70-year-old man presented with excruciating pain, redness, and diminution of vision in his left eye for 2 weeks after washing his hair with tap water.

Triple chamber: a clinical rarity after deep anterior lamellar keratoplasty and role of optical coherence tomography in management.

Purpose: To report a case demonstrating triple chamber following deep anterior lamellar keratoplasty (DALK) and its successful intra-operative optical coherence tomography-guided management.

Method: Case report of a young male with macular corneal dystrophy, who underwent DALK in his left eye by Big-Bubble technique. The surgery was uneventful.

Metastatic renal cell carcinoma presenting as one-and-a-half syndrome.

We report a case of 43-year-old male, presented with sudden onset binocular diplopia on lateral gazes. Ocular examination showed features of ipsilateral one-and-a-half syndrome. Comprehensive systemic work in conjunction with magnetic resonance imaging of the brain illustrated irregular mixed solid and cystic lesions in the brainstem, possibly indicative of brain metastases.

Descemet stripping automated endothelial keratoplasty.

Endothelial keratoplasty is at present the gold standard for surgical treatment of corneal endothelial pathologies not associated with significant corneal scar. Tremendous progress has been made in recent years in improving the technology of endothelial keratoplasty techniques, such as descemet stripping automated endothelial keratoplasty (DSAEK) and descemet membrane endothelial keratoplasty. In this review, we discuss the current techniques and outcomes of DSAEK.

A new and simple method to construct root locus of general fractional-order systems.

Recently fractional-order (FO) differential equations are widely used in the areas of modeling and control. They are multivalued in nature hence their stability is defined using Riemann surfaces. The stability analysis of FO linear systems using the technique of Root Locus is the main focus of this paper.
