Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Band Gap and Polarization Tuning of Ion-Doped XNbO₃ (X = Li, K, Na, Ag) for Photovoltaic and Energy Storage Applications

Molecules
Using a microscopic model and Green’s function theory, we have calculated the band gap energy and the polarization of LiNbO3, KNbO3, AgNbO3, and NaNbO3. The effects by substitution of different ions at A or/and B sites for doping concentration x = 0–0.1 ...

Macroscopic-microscopic model of nuclear potential energy

EPJ Web of Conferences, 2017
To improve the evaluation of nuclear observables, refined models are to be used more and more as underlying analysis tools. Fission is a complex process and is the less accurately described with current models. Standard evaluation models rely on the Hill-

PERFORMANCE EVALUATION OF ROUNDABOUTS USING A MICROSCOPIC SIMULATION MODEL [PDF]

Scientific Journal of Silesian University of Technology. Series Transport, 2019
Contemporary planning of the road network in cities assumes the use of transport models. The microscopic model allows provision of information and decision-making regarding, for example, emissions, traffic organisation, geometrics of the intersection and

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Coupling microscopic and mesoscopic models for crowd dynamics with emotional contagion

Frontiers in Physics
We are interested in modeling and simulating the dynamics of human crowds, where the spreading of an emotion (specifically fear) influences the pedestrians’ behavior.

S_{4} Symmetric Microscopic Model for Iron-Based Superconductors

Physical Review X, 2012
Although iron-based superconductors are multiorbital systems with complicated band structures, we demonstrate that the low-energy physics which is responsible for their high-T_{c} superconductivity is essentially governed by an effective two-orbital ...

Recursive simulation and experimental frame for multiscale simulation [PDF]

, 2009
In this paper, we present a formal and operational framework for multiscale modeling and simulation. We focus on scale transfer viewed as the coupling between two models of the same system, one at the microscopic scale and the other at the macroscopic ...

Microscopic models of hardness [PDF]

Journal of Superhard Materials, 2010
Recent developments in the field of microscopic hardness models have been reviewed. In these models, the theoretical hardness is described as a function of the bond density and bond strength. The bond strength may be characterized by energy gap, reference potential, electron-holding energy or Gibbs free energy, and different expressions of bond ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
