Non-operative management of rectal cancer: understanding tumor biology [PDF]

open access: yesMinerva Chirurgica, 2018
The management of locally-advanced rectal cancer involves a combination of chemotherapy, chemoradiation, and surgical resection to provide excellent local tumor control and overall survival. However, aspects of this multimodality approach are associated with significant morbidity and long-term sequelae.

On ξ(s)-Quadratic Stochastic Operators on Two-Dimensional Simplex and Their Behavior

open access: yesAbstract and Applied Analysis, 2013
A quadratic stochastic operator (in short QSO) is usually used to present the time evolution of differing species in biology. Some quadratic stochastic operators have been studied by Lotka and Volterra.

A homotopy perturbation method with Elzaki transformation for solving the fractional Biswas–Milovic model

open access: yesOpen Physics, 2023
In this research, we use the homotopy perturbation method (HPM) combined with the Elzaki transform to investigate the fractional Biswas–Milovic equation (BME) within the framework of the Caputo operator.

Development and Validation of a Novel Prognostic Model for Acute Myeloid Leukemia Based on Immune-Related Genes

open access: yesFrontiers in Immunology, 2021
The prognosis of acute myeloid leukemia (AML) is closely related to immune response changes. Further exploration of the pathobiology of AML focusing on immune-related genes would contribute to the development of more advanced evaluation and treatment ...

Improved gravitation field algorithm and its application in hierarchical clustering. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Gravitation field algorithm (GFA) is a new optimization algorithm which is based on an imitation of natural phenomena. GFA can do well both for searching global minimum and multi-minima in computational biology.

An Optimal Control Formulation of Pulse-Based Control Using Koopman Operator [PDF]

open access: yes, 2018
In many applications, and in systems/synthetic biology, in particular, it is desirable to compute control policies that force the trajectory of a bistable system from one equilibrium (the initial point) to another equilibrium (the target point), or in ...
