During the ongoing COVID‐19 pandemic, an artifact with hyperintense signal was observed on the brain images of a number of patients or research subjects, particularly those with heavy body weight and/or increased respiratory rate. The artifact was primarily seen on 3D or 2D sagittal or coronal T2‐weighted images, although it occasionally also appeared ...

Condensed DNA: Condensing the concepts
Progress in Biophysics and Molecular Biology, 2011DNA is stored in vivo in a highly compact, so-called condensed phase, where gene regulatory processes are governed by the intricate interplay between different states of DNA compaction. These systems often have surprising properties, which one would not predict from classical concepts of dilute solutions.

With the recent advances in surface fabrication technologies, condensation heat transfer has seen a renaissance. Hydrophobic and superhydrophobic surfaces have all been employed as a means to enhance condensate shedding, enabling micrometric droplet departure length scales.

Many proteins, particularly those that are intrinsically disordered and carry charges have a tendency to undergo liquid liquid phase separation (LLPS). Phase separation is a widespread mechanism by which cells concentrate a set of proteins to perform molecular reactions, and appear to compartmentalize molecular functions.

AbstractAn integral domain D with identity is condensed (resp., strongly condensed) if for each pair of ideals I, J of D, IJ = {ij ; i ∈ I; j ∈ J} (resp., IJ = iJ for some i ∈ I or IJ = Ij for some j ∈ J). We show that for a Noetherian domain D, D is condensed if and only if Pic(D) = 0 and D is locally condensed, while a local domain is strongly ...

Recent progress in our understanding of DNA condensation includes the observation of the collapse of single DNA molecules, greater insights into the intermolecular forces driving condensation, the recognition of helix-structure perturbation in condensed DNA, and the increasing recognition of the likely biological consequences of condensation.

Condensed and Strongly Condensed Domains
Canadian Mathematical Bulletin, 2008AbstractThis paper deals with the concepts of condensed and strongly condensed domains. By definition, an integral domain R is condensed (resp. strongly condensed) if each pair of ideals I and J of R, I J = ﹛ab/a ∈ I, b ∈ J﹜ (resp. I J = a J for some a ∈ I or I J = Ib for some b ∈ J).

Multizone Condensers: Desuperheating, Condensing, Subcooling
Heat Transfer Engineering, 1981This article examines the design of multizone condensers. It also marks the first published discussion of the existence of a “wet desuperheating zon” in every multizone condenser with a “dry desuperheating zone. ’Considered in this discussion are only single component vapors in shell-and-tube heat exchangers with single shell-side ...
