Modulating Enzyme–Ligand Binding with External Fields

open access: yesBiophysica
Protein enzymes are highly efficient catalysts that exhibit adaptability and selectivity under diverse biological conditions. In some organisms, such as bacteria, structurally similar enzymes, for instance, shikimate kinase (SK) and adenylate kinase (AK),

Experience of Virtual Help in a Simulated BCI Stroke Rehabilitation Serious Game and How to Measure It

open access: yesSensors
Designers of digital rehabilitation experiences can accommodate error-prone input devices like brain–computer interfaces (BCIs) by incorporating virtual help mechanisms to adjust the difficulty, but it is unclear on what grounds users are willing to ...

Importance of the doctrines of frustration and force majeure in light of COVID-19

open access: yes, 2021
The ongoing COVID-19 pandemic, and the measures to contain its spread, significantly impact contractual relationships in many ways. Unforeseen and uncontrollable events could be legitimate defences for being unable to execute obligations undertaken ...

Spin delta-chain with competing exchange interactions

open access: yesИзвестия высших учебных заведений. Поволжский регион: Физико-математические науки
Background. Low-dimensional quantum magnets based on geometrically frustrated lattices are of considerable interest last time. As a typical example of such systems is the delta-chain which is a linear chain of triangles with spins on vertices.
