Optics in a field of gravity [PDF]
American Journal of Physics, 2009 An observer at rest in a uniformly accelerated reference frame experiences a parallel gravitational field. As a result, rays of light are formed as circular arcs instead of being straight lines. We deduce how a sphere at rest in this frame and a freely falling sphere in this frame appear to an observer at rest.

Crustal structure of the spreading plate boundary in Iceland and the north Atlantic from gravity data [PDF]
, 1994 Gravity datasets from two geothermal areas in Iceland, an Iceland-wide gravity dataset, and marine gravity data from the Reykjanes Ridge at 58˚N, which can be seen as the submarine extension of the Icelandic accretionary system, have been studied in this

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Molecular Oncology, EarlyView.Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Versatile vector tools for efficient protein screening across multiple expression systems
FEBS Open Bio, EarlyView.A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Method of discrete approximations of gravity field on delineation of promising sections
Геофизический журнал, 2014 The theme considered in the article is connected with the numerical solution of Laplas equation while solving the problem of gravimetry. It is shown, that the use of a method of discrete approximations reduces a problem of restoration of values of a ...

Why gravity is not an entropic force [PDF]
, 2010 The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force.
