Physics Letters B, 1991 Abstract Several infinite sets of models of random surfaces, defined by means of integrals over matrix ensembles, are solved in a double-scaling limit. These models are exactly soluble in at least two distinct large N limits. The triangulated surfaces are complicated due to the existence of two distinct kinds of vertices in the triangulations. In one

Surface Complexation Modeling of Biomolecule Adsorptions onto Titania
Colloids and Interfaces, 2019 The adsorption of nucleic acid components on the surface of nanocrystalline titanium dioxide (anatase, pHpzc = 6.5) in NaCl solutions was investigated using potentiometric titrations and multibatch adsorption experiments over a wide range of pH and ionic

Mathematische Annalen, 1984 The content of this paper is a classification of all two dimensional complex manifolds which are homogeneous under the action of a real Lie group of holomorphic automorphisms. The problem of classifying homogeneous surfaces has been considered in various different settings and of these results we note the following.

Computational complexity of combinatorial surfaces [PDF]
Proceedings of the sixth annual symposium on Computational geometry - SCG '90, 1990 We investigate the computational problems associated with combinatorial surfaces. Specifically, we present an algorithm (based on the Brahana-Dehn-Heegaard approach) for transforming the polygonal schema of a closed triangulated surface into its canonical form in O(n log n) time, where n is the total number of vertices, edges and faces. We also give an

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.

Surface Reactions in Natural Aqueous Colloidal Systems
CHIMIA, 1989 Natural colloids are mixtures of inorganic and organic polymers resulting from weathering processes. These materials include layer-type aluminosilicates, hydrous oxides, and biodegraded organic matter.

Robustness surfaces of complex networks [PDF]
Scientific Reports, 2014 Despite the robustness of complex networks has been extensively studied in the last decade, there still lacks a unifying framework able to embrace all the proposed metrics. In the literature there are two open issues related to this gap: (a) how to dimension several metrics to allow their summation and (b) how to weight each of the metrics.

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)
