Heating of Quiescent Coronal Loops Caused by Nearby Eruptions Observed with the Solar Dynamics Observatory and the Solar Upper Transition Region Imager

open access: yesThe Astrophysical Journal, 2023
How structures, e.g., magnetic loops, in the upper atmosphere, i.e., the transition region and corona, are heated and sustained is one of the major unresolved issues in solar and stellar physics.

Watching Genes Loop the Loop

open access: yesPLoS Biology, 2013
Most cells of a given species contain essentially the same complement of genes, yet individual genetically identical cells can assume dramatically different appearances and behaviours. This is achieved largely by the regulation of the transcription of individual genes, orchestrated by the specific binding of proteins to nearby sites in the genome—a ...

Un paseo por los anillos de bucles

open access: yesRevista Integración, 2012
La teoría de anillos de bucles no es solamente una generalización de los anillos de grupos: es una teoría en sí misma, con origen y aún en movimiento. El concepto de anillo de bucles surge en 1944 en los trabajos de R.H.

DNA loops after cell lysis resemble chromatin loops in an intact nucleus

open access: yesThe Ukrainian Biochemical Journal, 2018
The comet assay has proved itself to be not only a method of detection of DNA damages at the level of individual cells but also an approach for investigation of spatial organization of DNA loop domains in nucleoids.

Classifying BPS bosonic Wilson loops in 3d N $$ \mathcal{N} $$ = 4 Chern-Simons-matter theories

open access: yesJournal of High Energy Physics, 2022
We study the possible BPS Wilson loops in three-dimensional N $$ \mathcal{N} $$ = 4 Chern-Simons-matter theory which involve only the gauge field and bilinears of the scalars.

Closing the loops: chromatin loop dynamics after DNA damage

open access: yesNucleus
Chromatin is a dynamic polymer in constant motion. These motions are heterogeneous between cells and within individual cell nuclei and are profoundly altered in response to DNA damage.

Loop-check free sequent calculi for unary fragment of temporal logic

open access: yesLietuvos Matematikos Rinkinys
This paper explores the construction of an efficient sequent calculus for a selected fragment of porpositional linear temporal logic (PLTL), extending the ideas of classical calculi discussed in [1], and builds upon previous investigations into the ...

The Horizons of Observability in PT-symmetric Four-site Quantum Lattices

open access: yesActa Polytechnica, 2011
One of the key merits of PT-symmetric (i.e., parity times time reversal symmetric) quantum Hamiltonians H lies in the existence of a horizon of the stability of the system. Mathematically speaking, this horizon is formed by the boundary of the domain D(H)

Novel BPS Wilson loops in three-dimensional quiver Chern–Simons-matter theories

open access: yesPhysics Letters B, 2016
We show that generic three-dimensional N=2 quiver super Chern–Simons-matter theories admit Bogomol'nyi–Prasad–Sommerfield (BPS) Drukker–Trancanelli (DT) type Wilson loops.
