Mathematical modeling can offer valuable insights into the behavior of biological systems upon treatment. Different mathematical models (empirical, semi-empirical, and mechanistic) have been designed to predict the efficacy of either hyperthermia (HT), radiotherapy (RT), or their combination. However, mathematical approaches capable of modeling cel...

Hyperthermia (HT) combined with irradiation is a well-known concept to improve the curative potential of radiotherapy. Technological progress has opened new avenues for thermoradiotherapy, even for recurrent head and neck squamous cell carcinomas (HNSCC). Preclinical evaluation of the curative radiosensitizing potential of various HT regimens remai...

Radiotherapy can effectively kill malignant cells, but the doses required to cure cancer patients may inflict severe collateral damage to adjacent healthy tissues. Recent technological advances in the clinical application has revitalized hyperthermia treatment (HT) as an option to improve radiotherapy (RT) outcomes. Understanding the synergistic ef...

Photosynthetic systems utilize adaptability to respond efficiently to fluctuations in their light environment. As a result, large photosynthetic yields can be achieved in conditions of low light intensity, while photoprotection mechanisms are activated in conditions of elevated light intensity. In sharp contrast with these observations, current the...

Radiotherapy can effectively kill malignant cells, but the doses required to cure cancer patients can often not be applied as they come at the cost of severe collateral damage to adjacent healthy tissues. Hyperthermia (HT) is a promising option to improve the outcome of radiation treatment (RT) and is increasingly applied in the clinics by incorpor...

Photon-excitation and exciton migration in photosynthetic light harvesting membranes is followed by a charge separation which initiates the reduction of several cofactors and eventually, sustains the charge gradient that drives the synthesis of Adenosine Triphosphate. Earlier, the interplay between charge dynamics and light intensity has been prove...

The promise of any small improvement in the performance of light-harvesting devices, is sufficient to drive enormous experimental efforts. However these efforts are almost exclusively focused on enhancing the power conversion efficiency with specific material properties and harvesting layers thickness, without exploiting the correlations present in...

Thermal light sources can produce photons with strong spatial correlations. We study the role that these correlations might potentially play in bacterial photosynthesis. Our findings show a relationship between the transversal distance between consecutive absorptions and the efficiency of the photosynthetic process. Furthermore, membranes where the...

Harvesting of sunlight underpins Life on Earth as well as driving novel energy device design. Though several experiments suggest that excitation energy transport and charge separation within a photosynthetic membrane may benefit from the quantum nature of their dynamics, the effects of spatial coherences in the incident light have been largely igno...

Clasicaly, the computational time required to calculate the energy of quantum systems escales exponentially with size, however, this calculation can be made in polinomial time using a recursive quantum algorithm termed phase estimation algorithm (PEA). This reduces the number of qubist required to read out a register from twenty to four approximate...

We present a thermodynamic model of mixtures in which the Helmholtz energy is computed from an extended corresponding states (ECS) method with a correction term. The ECS model is based upon the van der Waals one-fluid theory with pure-component shape factors represented as functions of reduced temperature and density. The correction term is given b...

We report an extended corresponding states model optimised for accurate prediction of the thermodynamic properties and vapour–liquid equilibria of natural gases and similar mixtures. The corresponding states model uses methane as the reference fluid and employs shape factors for pure components that were reported recently [Fluid Phase Equilib. 204...

We present a model for the calculation of mixture properties. This model is based on the mixture residual Helmholtz energy given by the sum of two terms: one is the residual Helmholtz energy calculated by an extended corresponding states (ECS) model while the other is a correction term. The ECS model is based on methane as the reference fluid and s...
