Wasserstein Distance Guided Representation Learning for Domain Adaptation
AAAI Conference on Artificial Intelligence, 2017 Domain adaptation aims at generalizing a high-performance learner on a target domain via utilizing the knowledge distilled from a source domain which has a different but related data distribution.

FEBS Letters, Volume 599, Issue 7, Page 971-988, April 2025.We present the first solution structure of the Ca2+‐depleted LETM1 F‐EF‐hand through a D676A/N678A Ca2+ binding‐deficient mutant, revealing a closed hydrophobic cleft caused by a unique F1‐helix pivot. The apo LETM1 F‐EF‐hand exhibits regiospecific hot and cold unfolding, sensitivity to physiological pH changes and potential for promiscuous heterotypic

QMEANDisCo—distance constraints applied on model quality estimation
Bioinform., 2019 Motivation Methods that estimate the quality of a 3D protein structure model in absence of an experimental reference structure are crucial to determine a model’s utility and potential applications.

FEBS Letters, EarlyView.α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

On Distance Spectral Radius and Distance Energy of Graphs [PDF]
MATCH Commun. Math. Comput. Chem. 64 (2010) 261-280, 2011 For a connected graph, the distance spectral radius is the largest eigenvalue of its distance matrix, and the distance energy is defined as the sum of the absolute values of the eigenvalues of its distance matrix. We establish lower and upper bounds for the distance spectral radius of graphs and bipartite graphs, lower bounds for the distance energy of

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

International Review of Research in Open and Distributed Learning, 2002 We know that significant organizational change must have roots both at the top of an organization and “in the trenches” amongst those who must implement the change.

International Review of Research in Open and Distributed Learning, 2017 Today the digital divide is measured not so much by access to the internet but by people's ability to interact in cyberspace, which calls for specific digital communication skills.

Information and Computation, 1990 AbstractA model of learning by distances is presented. In this model a concept is a point in a metric space. At each step of the learning process the student guesses a hypothesis and receives from the teacher an approximation of its distance to the target. A notion of a distance measuring the proximity of a hypothesis to the correct answer is common to
