Estimated Incidence of Ophthalmic Conditions Associated with Optic Nerve Disease in Middle Tennessee [PDF]

open access: yesarXiv, 2017
Aims. The objective of this paper is to determine the incidence of ophthalmic disease potentially leading to optic nerve disease in Middle Tennessee. Methods. We use a retrospective population-based incidence study design focusing on the population of middle Tennessee and its nearby suburbs (N=3 397 515). The electronic medical records for all patients

Bifurcation analysis of waning-boosting epidemiological models with repeat infections and varying immunity periods [PDF]

open access: yesarXiv, 2023
We consider the SIRWJS epidemiological model that includes the waning and boosting of immunity via secondary infections. We carry out combined analytical and numerical investigations of the dynamics. The formulae describing the existence and stability of equilibria are derived.

Rational Design of Metal–Organic Frameworks for Pancreatic Cancer Therapy: from Machine Learning Screening to In Vivo Efficacy

open access: yesAdvanced Materials, EarlyView.
This work explores the MOF landscape to select a single, optimal candidate for successfully delivering cancer drugs (gemcitabine, paclitaxel, SN‐38) into tough pancreatic tumors. Machine learning and simulations guide this search, demonstrating colloidal stability, excellent biocompatibility, cellular uptake, and sustained release.

Existence of periodic solutions of a periodic SEIRS model with general incidence [PDF]

open access: yesarXiv, 2015
For a family of periodic SEIRS models with general incidence, we prove the existence of at least one endemic periodic orbit when R_0>1. Additionally, we prove the existence of a unique disease-free periodic orbit, that is globally asymptotically stable when R_0<1.

Codimension-Two Bifurcations of an SIR-Type Model for COVID-19 and Their Epidemiological Implications [PDF]

open access: yesarXiv, 2023
We study the codimension-two bifurcations exhibited by a recently-developed SIR-type mathematical model for the spread of COVID-19, as its two main parameters -- the susceptible individuals' cautiousness level and the hospitals' bed-occupancy rate -- vary over their domains.

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.
