Prolongations of tensor fields and connections to tangent bundles I -- General theory -- [PDF]

open access: yesJournal of the Mathematical Society of Japan, 1966
Publisher Summary Using the notion of complete lift it is shown that G structures as a pseudo-Riemannian structure, an almost complex structure and a symplectic structure on M induce similar structures on the tangent bundle T(M). An unexpected but perhaps more interesting result is that each pseudo-Riemannian (resp.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Common neighbours and the local-community-paradigm for topological link prediction in bipartite networks

open access: yesNew Journal of Physics, 2015
Bipartite networks are powerful descriptions of complex systems characterized by two different classes of nodes and connections allowed only across but not within the two classes.

Analytical studies of the behaviour of semi-rigid non-sway frames with tubular columns. [PDF]

open access: yes, 1999
This thesis reports the research investigation on the behaviour of non-sway frames with SHS columns taking into consideration the influence of semi-rigid flowdrill connections.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

The image of society in the theory of Islamic literature

open access: yesآداب الكوفة, 2011
One of the important principles in the theory of Islamic literature is to look at any social phenomenon through its true location in the context of the social system that is subject to the divine laws that govern the movement of history and ...

A connection between gravitational scalar-tensor theories and generalized hybrid theories

open access: yesPhysics Letters B
We establish a correspondence between higher-derivative gravitational scalar-tensor theories of the form $Ψ(R,(\nabla R)^2,\Box R)$ and generalized hybrid metric-Palatini models $f(R,\mathcal{R})$. Restricting to the physically relevant case of linear dependence on $\Box R$, we make explicit that both frameworks can be reformulated in the Einstein ...

Connections between the Sznajd model with general confidence rules and graph theory [PDF]

open access: yesPhysical Review E, 2012
The Sznajd model is a sociophysics model, that is used to model opinion propagation and consensus formation in societies. Its main feature is that its rules favour bigger groups of agreeing people. In a previous work, we generalized the bounded confidence rule in order to model biases and prejudices in discrete opinion models.

Artificial Intelligence and Mental Well‐Being in Adult Education: Implications for Practice and Professional Responsibility

open access: yesNew Directions for Adult and Continuing Education, EarlyView.
ABSTRACT Mental well‐being is central to adult learner success, yet many adult education institutions lack capacity to provide timely and accessible support. This article examines how artificial intelligence (AI) can strengthen mental health–adjacent supports in adult and continuing higher education, with attention to professional practice and ...
