Substantive scientific letter writing is a cost-effective mode of complementing observational and experimental research. The value of such philosophically uncommitted and unsponsored well-balanced scientific activity has been relegated. Critical letter writing entails the abilities to: maintain rational scepticism; refuse to conform in order to explain data; persist in keeping common sense centre-stage; exercise logic to evaluate the biological significance of mathematical figures, including statistics, and the ability to sustain the will to share insights regarding disease mechanisms on an ostensibly lower (...) research platform. During peer review, innovative letter writing may share the occasionally unfortunate fate of innovative research. Rejected scientific letters do not automatically lose copyright. Periodicals with high letter loads will see some valuable contributions wasted, but that is the price for maintaining autonomy in scientific publication. The scientific community is an integrated whole that must respect the rights of authors at all levels. Unauthorised forwarding of rejected letters sets the dangerous precedent of justifying unjust means. (shrink)

Regulation of microtubule (MT) dynamics is essential for many cellular processes, but the machinery that controls MT dynamics remains poorly understood. MT plus‐end tracking proteins (+TIPs) are a set of MT‐associated proteins that dynamically track growing MT ends and are uniquely positioned to govern MT dynamics. +TIPs associate with each other in a complex array of inter‐ and intra‐molecular interactions known as the “+TIP network.” Why do so many +TIPs bind to other +TIPs? Typical answers include the ideas that these (...) interactions localize proteins where they are needed, deliver proteins to the cortex, and/or create regulatory pathways. We propose an additional and more mechanistic hypothesis: that +TIPs bind each other to create a superstructure that promotes MT assembly by constraining the structural fluctuations of the MT tip, thus acting as a polymerization chaperone.

The Yogārṇava is a Sanskrit compendium on yoga that has not been published, translated or even mentioned in secondary literature on yoga. Citations attributed to it occur in several premodern commentaries and compendiums on yoga, and a few published library catalogues report manuscripts of a work on yoga called the Yogārṇava. This article presents the results of the first academic study of the text. It has attempted to answer basic questions, such as the work’s provenance and textual sources. The authors (...) then discuss the importance of the Yogārṇava within the broader history of yoga based on their identification of citations and parallel verses in other Sanskrit texts and a detailed analysis of the Yogārṇava’s content.

Книга является едва ли не первой попыткой отрефлектировать, как происходило становление философского самосознания в России.

In this letter we demonstrate that the fermionic zero modes on a superconducting domain wall can be associated to an one dimensional \ supersymmetry that contains non-trivial topological charges. In addition, the system also possesses three distinct \ supersymmetries with non-trivial topological charges and we also study some duality transformations of the supersymmetric algebras.

The volume presents a set of invited papers based on analyses of legal discourse drawn from a number of international contexts where often the English language ...
