Criterion for the resolvent set of nonsymmetric tridiagonal operators [PDF]

open access: yesProceedings of the American Mathematical Society, 1995
We study nonsymmetric tridiagonal operators acting in the Hilbert space ℓ 2 {\ell ^2} and describe the spectrum and the resolvent set of such operators in terms of a continued fraction related to the resolvent.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

On The Metric Dimension of Some Operation Graphs

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2018
Let  be a simple, finite, and connected graph. An ordered set of vertices of a nontrivial connected graph  is  and the -vector  represent vertex  that respect to , where  and  is the distance between vertex  and  for . The set  called a resolving set for

Symmetry breaking in tournaments [PDF]

open access: yes, 2013
We provide upper bounds for the determining number and the metric dimension of tournaments. A set of vertices S in V(T) is a determining set for a tournament T if every nontrivial automorphism of T moves at least one vertex of S, while S is a resolving ...

Prioritized Repairing and Consistent Query Answering in Relational Databases [PDF]

open access: yes, 2011
A consistent query answer in an inconsistent database is an answer obtained in every (minimal) repair. The repairs are obtained by resolving all conflicts in all possible ways.

The distance 2-resolving domination number of graphs

open access: yes, 2021
The distance 2-resolving dominating set is the combination of two concepts, the resolving set and the distance 2-dominating set. The distance 2-resolving dominating set is a set that is both a distance 2-dominating set and a resolving set. The distance 2-

RAD50 missense variants differentially affect the DNA damage response and mitotic progression

open access: yesFEBS Letters, EarlyView.
RAD50 incorporates into the MRN complex and initiates the DNA damage response. Furthermore, RAD50 promotes mitotic progression. RAD50 missense variants capable of forming an MRN complex supported the DNA damage response and mitotic features to different extents in complementation experiments, indicating these functions are separable and might impact ...

Resolvability of A-, CA- and PCA-sets in compacta

open access: yesTopology and its Applications, 1997
For a cardinal \(\kappa\), a space \(X=(X,{\mathcal T})\) is said to be \(\kappa\)-resolvable if \({\mathcal P}(X)\) contains \(\kappa\)-many pairwise disjoint \(\mathcal T\)-dense sets; in this terminology, \(X\) is resolvable if \(X\) is 2-resolvable, and \(X\) is maximally resolvable if \(X\) is \(\Delta(X)\)-resolvable, where \(\Delta(X)=\min\{|U|:\

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Uniquely identifying vertices and edges of a heptagonal snake graph using distance formulas

open access: yesAIMS Mathematics
Consider a city with a network of roads where surveillance cameras are positioned at key intersections. To uniquely determine the position of any car, the minimal number of cameras needed is determined by using the metric dimension of the network ...
