Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Enumeration of dissociation sets in grid graphs

open access: yesAIMS Mathematics
A dissociation set of a graph $ G $ refers to a set of vertices inducing a subgraph with maximum degree at most 1 and serves as a generalization of two fundamental concepts in graph theory: Independent sets and induced matchings.

Parameterised Enumeration for Modification Problems

open access: yesAlgorithms, 2019
Recently, Creignou et al. (Theory Comput. Syst. 2017), introduced the class DelayFPT into parameterised complexity theory in order to capture the notion of efficiently solvable parameterised enumeration problems. In this paper, we propose a framework for

Families of prudent self-avoiding walks [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
A self-avoiding walk on the square lattice is $\textit{prudent}$, if it never takes a step towards a vertex it has already visited. Préa was the first to address the enumeration of these walks, in 1997.

Induction by Enumeration

open access: yesInformation and Computation, 2001
AbstractInduction by enumeration has a clear interpretation within the numerical paradigm of inductive discovery (i.e., the one pioneered by E. M. Gold (1967, Inform. and Control10, 447–474)). The concept is less easily interpreted within the first-order paradigm discussed by K. T. Kelly (1996, “The Logic of Reliable Inquiry,” Oxford Univ.

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

open access: yesPopulation Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

Methods currently applied to study the prevalence of Clostridioides difficile in foods

open access: yesAIMS Agriculture and Food, 2020
Clostridioides difficile is responsible for most cases of antibiotic- and hospital-associated diarrhoea. Several studies have demonstrated the presence of C.

Dendritic cells steering antigen and leukocyte traffic in lymph nodes

open access: yesFEBS Letters, EarlyView.
Dendritic cells are key players in the activation of T cells and their commitment to effector function. In this In a Nutshell Review, we will discuss how dendritic cells guide the trafficking of antigen and leukocytes in the lymph node, thus influencing T‐cell activation processes. Dendritic cells (DCs) play a central role in initiating and shaping the

Enumeration of Hypergraphs

open access: yesEuropean Journal of Combinatorics, 2001
AbstractIn this paper, we will study enumeration of hypergraphs. Let Spbe a symmetric group acting on ap-setX. It induces the permutation group Sp*acting on the set of all subsets ofX. Our problem is reduced to finding a good formula for the cycle index ofSp* .
