On Sequences of J. P. King‐Type Operators

Journal of Function Spaces, Volume 2019, Issue 1, 2019., 2019
This survey is devoted to a series of investigations developed in the last fifteen years, starting from the introduction of a sequence of positive linear operators which modify the classical Bernstein operators in order to reproduce constant functions and x2 on [0,1]. Nowadays, these operators are known as King operators, in honor of J. P.

Unravelling the Spatiotemporal Exciton Dynamics in Electrically Pumped Organic Laser Diodes

Laser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.
High‐speed OLED measurements combined with advanced simulations reveal how singlet, triplet, and polaron dynamics drive key loss channels that hinder organic semiconductor lasing, while presenting strategies to overcome them. Abstract Organic materials offer wide‐band emission covering regions of the spectrum unachievable by conventional semiconductors.

Weighted Korovkin‐Type Theorem and Some Properties of Szász–Mirakjan Operators Preserving Exponential Functions via Power Series Statistical Convergence

Journal of Function Spaces, Volume 2026, Issue 1, 2026.
In this article, we establish a weighted Korovkin‐type approximation theorem within the framework of power series statistical convergence and provide a systematic extension of classical Korovkin theory to weighted function spaces. Furthermore, we investigate the approximation properties of the Szász–Mirakjan operators preserving exponential functions ...

Primary Ovarian Malignant Mixed Mullerian Tumour: A Case Report and Brief Review of Literature [PDF]

Journal of Clinical and Diagnostic Research, 2016
Malignant Mixed Mullerian Tumour of the Ovary (OMMMT), also referred to as carcinosarcoma is a very rare tumour accounting for less than 1% of all ovarian cancers. Due to the rarity of OMMMT, little is known about the disease course and outcome of women

A New Approach for Calculating Texture Coefficients of Different Rocks With Image Segmentation and Image Processing Techniques

Microscopy Research and Technique, Volume 88, Issue 10, Page 2612-2629, October 2025.
This study calculated the texture coefficient (TC) values of 20 different rock textures with magmatic, metamorphic, and sedimentary origins, which underwent image segmentation using a novel approach. ABSTRACT The texture coefficient (TC) is a critical parameter used to analyze the microstructural characteristics of rocks and predict their mechanical ...

Recurrence of Primary Vascular Leiomyosarcoma Five Years after Initial Diagnosis in the Lower Extremity

Case Reports in Oncological Medicine, Volume 2018, Issue 1, 2018., 2018
Primary leiomyosarcomas of vascular origin are rare tumors. They frequently arise within the inferior vena cava; however, the peripheral vein was also affected. To date, only a few hundred cases have been reported in the world literature. Although it is an extremely aggressive tumor, the symptoms may be unspecific, especially in the lower extremities ...
