Short-length routes in low-cost networks via Poisson line patterns [PDF]

, 2008
In designing a network to link n points in a square of area n, we might be guided by the following two desiderata. First, the total network length should not be much greater than the length of the shortest network connecting all points.

Genomic Comparisons Reveal Microevolutionary Differences in Mycobacterium abscessus Subspecies

Frontiers in Microbiology, 2017
Mycobacterium abscessus, a rapid-growing non-tuberculous mycobacterium, has been the cause of sporadic and outbreak infections world-wide. The subspecies in M. abscessus complex (M. abscessus, M. massiliense, and M.

Graphs admitting antimagic labeling for arbitrary sets of positive integers [PDF]

, 2017
A connected graph G=(V,E) with m edges is called universal antimagic if for each set B of m positive integers there is an bijective function f:E→B such that the function f˜:V→N defined at each vertex v as the sum of all labels of edges incident to v is ...

On subsets of R-n spanning it via positive integers as multipliers

, 2021
In this article we investigate which subsets of R-n generate the whole R-n by the use of positive integers taken as multipliers, as well as a related question of which subsemigroups of R-n are generated by different subsets of R-n.

Expression of CD274 mRNA Measured by qRT-PCR Correlates With PD-L1 Immunohistochemistry in Gastric and Urothelial Carcinoma

Frontiers in Oncology, 2022
Programmed death-ligand 1 (PD-L1) immunohistochemistry (IHC) is widely used to predict the clinical responses to immune checkpoint inhibitors (ICIs). However, PD-L1 IHC suffers from the complexity of multiple testing platforms and different cutoff values

Hypomethylation mediates genetic association with the major histocompatibility complex genes in Sjögren's syndrome.

PLoS ONE, 2021
Differential methylation of immune genes has been a consistent theme observed in Sjögren's syndrome (SS) in CD4+ T cells, CD19+ B cells, whole blood, and labial salivary glands (LSGs).

Prediction of β-barrel membrane proteins by searching for restricted domains [PDF]

, 2005
BACKGROUND: The identification of beta-barrel membrane proteins out of a genomic/proteomic background is one of the rapidly developing fields in bioinformatics. Our main goal is the prediction of such proteins in genome/proteome wide analyses.

Explaining global increases in water use efficiency: why have we overestimated responses to rising atmospheric CO(2) in natural forest ecosystems? [PDF]

PLoS ONE, 2013
The analysis of tree-ring carbon isotope composition (δ(13)C) has been widely used to estimate spatio-temporal variations in intrinsic water use efficiency (iWUE) of tree species.

Signatures of Perseveration and Heuristic-Based Directed Exploration in Two-Step Sequential Decision Task Behaviour

Computational Psychiatry
Processes formalized in classic Reinforcement Learning (RL) theory, such as model-based (MB) control, habit formation, and exploration have proven fertile in cognitive and computational neuroscience, as well as computational psychiatry. Dysregulations in

Simplicial and Conical Decomposition of Positively Spanning Sets

, 2020
We investigate the decomposition of a set $X$, which positively spans the Euclidean space $\mathbb{R}^{d}$ into a set of minimal positive bases, we call simplices, and into maximal sets positively spanning pointed cones, i.e. cones with exactly one apex.
