Equilibrium of truss and beam structures of inelastic materials

open access: yesJournal of Civil Engineering and Management, 2017
A physically based method for the determination of equilibrium for structures with inelastic response is described. The method is based on minimisation of the potential energy.

Example of two different potentials which have practically the same fixed-energy phase shifts

open access: yes, 1999
It is shown that the Newton-Sabatier procedure for inverting the fixed-energy phase shifts for a potential is not an inversion method but a parameter-fitting procedure.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Embedded density functional theory for covalently bonded and strongly interacting subsystems [PDF]

open access: yes, 2011
Embedded density functional theory (e-DFT) is used to describe the electronic structure of strongly interacting molecular subsystems. We present a general implementation of the Exact Embedding (EE) method [J. Chem. Phys.

Thermal transport in the Falicov-Kimball model

open access: yes, 2001
We prove the Jonson-Mahan theorem for the thermopower of the Falicov-Kimball model by solving explicitly for the correlation functions in the large dimensional limit. We prove a similar result for the thermal conductivity.

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Development of anti-twist mechanism for continuum manipulator and modeling focusing on bending stiffness

open access: yesNihon Kikai Gakkai ronbunshu, 2018
This paper proposes a new mechanism and a modeling method for continuum manipulators. The new mechanism is an anti-twist mechanism. Continuum manipulators have the merit of flexibility. However flexibility causes unexpected motions such as twisting under

N=1* model and glueball superpotential from Renormalization-Group-improved perturbation theory

open access: yes, 2004
A method for computing the low-energy non-perturbative properties of SUSY GFT, starting from the microscopic lagrangian model, is presented. The method relies on covariant SUSY Feynman graph techniques, adapted to low energy, and Renormalization-Group ...
