Manuscripts, Articles, Book Chapters and Other Papers

Cell heterogeneity plays an important role in patient responses to drug treatments. In many cancers, it is associated with poor treatment outcomes. Many modern drug combination therapies aim to exploit cell heterogeneity, but determining how to optimise responses from heterogeneous cell populations while accounting for multi-drug synergies remains a challenge. In this work, we introduce and analyse a general optimal control framework that can be used to model the treatment response of multiple cell populations that are treated with multiple drugs that mutually interact. In this framework, we model the effect of multiple drugs on the cell populations using a …

International Arab Journal of Dentistry

Rehabilitating the maxilla in the patient who has had surgical resection for mucormycosis poses a distinctive set of anatomical, surgical, and prosthetic challenges. The extensive maxillary bone loss after aggressive debridement often makes traditional implant-supported prosthetic options impossible. In these circumstances, zygomatic implants have proven to be a predictable, graftless solution, especially in patients with extremely atrophic maxillae. Where the bone loss is severe, the quad zygoma procedure—two implants for each zygomatic arch—is possible to support full arch rehabilitation with a fixed prosthesis. This report presents the successful rehabilitation of oral function and appearance in a patient with post-mucormycosis edentulous …

These areas are often interdependent: for instance, clinker replacement, production efficiency, and structural optimisation are all influenced by the 16 – 18 hour production cycle typical of precast manufacturing. Unlike the readymix sector, precast operates on a fast-paced, …

Decalcification Of Calcium Silicate Hydrate By Sulfate Attack: Material Degradation By Heterogeneous Charges, Muhan Wang, Xiangming Zhou, Chengbo Liu, Pan Wang, Dongshuai Hou

International Conference on Durability of Concrete Structures

Sulfate attack is a key factor limiting the durability of concrete in aggressive environments, primarily through the degradation of calcium silicate hydrate (C–S–H), the main binding phase of cement. This study investigates the molecular mechanisms of C–S–H decalcification under sulfate exposure by combining semi-empirical Born–Oppenheimer molecular dynamics (BOMD) with density functional theory (DFT). A C–S–H model with a Ca/Si ratio of 1.5 was simulated in aqueous environments with and without sulfate ions. BOMD trajectories revealed that while C–S–H remained largely stable in pure water, sulfate ions rapidly promoted Ca²⁺ desorption, leading to silicate chain fragmentation and Q²→Q¹ transitions. Electronic structure …
