Protein crystallization and structure determination at room temperature in the CrystalChip
FEBS Open Bio, EarlyView.This protocol describes the implementation of a simple and user‐friendly microfluidic device called CrystalChip that allows the production of crystals by the counter‐diffusion method and their in situ analysis by serial crystallography. As an illustration, it is applied to determine the 3D structure of three proteins from data collected at room ...

Factorization in Phase-Space Finite Geometry and Weak Mutually Unbiased Bases
African Scientific Reports, 2023 A phase-space factorization of lines in finite geometry G(m) with variables in Zm and its correspondence in finite Hilbert space H(m) for m a non-prime was discussed. Using the method of Good [15], lines in G(m) were factorized as products of lines G(mi)

The first Alexander Z[Z]-modules of surface-links and of virtual links [PDF]
Geom. Topol. Monogr. 14 (2008) 353-371, 2009 We characterize the first Alexander Z[Z]-modules of ribbon surface-links in the 4-sphere fixing the number of components and the total genus, and then the first Alexander Z[Z]-modules of surface-links in the 4-sphere fixing the number of components. Using the result of ribbon torus-links, we also characterize the first Alexander Z[Z]-modules of virtual

Parametric shortest-path algorithms via tropical geometry
, 2021 We study parameterized versions of classical algorithms for computing shortest-path trees. This is most easily expressed in terms of tropical geometry.

FEBS Open Bio, EarlyView.We provide a step‐by‐step guide for producing E140 antigen fragments from Plasmodium berghei (Pb1) and Plasmodium vivax (Pv1). Pb1/Pv1 are expressed in E. coli, solubilized by freeze–thawing, refolded by slow dilution, purified by affinity chromatography (IMAC), then concentrated and subjected to quality control.

From Fractal Geometry to Statistical Fractal
Recoletos Multidisciplinary Research Journal, 2013 The development from fractal geometry to fractal statistics was established in this paper. Interesting features such as self similarity, scale invariance, and the spacefilling property of objects (fractal dimension) of fractal geometry provided an ...

Geometry of biperiodic alternating links [PDF]
J. London Math. Soc. (2) 99 (2019), 807-830, 2018 A biperiodic alternating link has an alternating quotient link in the thickened torus. In this paper, we focus on semi-regular links, a class of biperiodic alternating links whose hyperbolic structure can be immediately determined from a corresponding Euclidean tiling. Consequently, we determine the exact volumes of semi-regular links.

Evaluation of synaptotagmin‐1 action models by all‐atom molecular dynamics simulations
FEBS Open Bio, EarlyView.We used molecular dynamics simulations to test models proposing that synaptotagmin‐1 facilitates membrane fusion by perturbing lipid bilayers, inducing membrane curvature and/or bridging membranes. The simulations show that synaptotagmin‐1 C2‐domains placed near the site of fusion hinder the ability of SNARE complexes to bring the membranes together ...
