Local factors influence the wild bee functional community at the urban-forest interface

open access: yesFrontiers in Ecology and Evolution
IntroductionUrban forests provide necessary habitat for many forest-associated bee species amidst development and fragmentation. These forest fragments provide a variety of important floral and non-floral resources for bees that encompass a diversity of ...

Interplay between RNA‐protein interactions and RNA structures in gene regulation

open access: yesFEBS Open Bio, EarlyView.
Methodological advances in mapping transcriptome‐wide RNA‐protein interactions and RNA structures have started to uncover the potential of RNP conformations in gene regulation. Competing RNA–RNA, RNA‐protein and protein–protein interactions shape the compaction and function of RNPs throughout their lifetime and may provide novel therapeutic targets in ...

Control of acoustic tone formation using shape geometry modifications and jet blowing in a cavity experiencing supersonic flow

open access: yesInternational Journal of Thermofluids
Acoustics tones have caused significant damage to sensitive electronic equipment and aircraft respectively. The effects become severe in cavities experiencing turbulent flows and could lead to human fatalities.

The distinguishing number and the distinguishing index of line and graphoidal graph(s)

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The distinguishing number (index) () of a graph is the least integer such that has a vertex labeling (edge labeling) with labels that is preserved only by a trivial automorphism.

Edge density affects demography of an exploited grassland bird

open access: yesEcosphere, 2021
Humans modify landscapes for a variety of reasons including agriculture, urbanization, and to facilitate recreation. Landscape modifications can lead to complete loss of existing cover types and/or fragmentation of remaining cover types.

Decomposing 8-regular graphs into paths of length 4

open access: yes, 2016
A $T$-decomposition of a graph $G$ is a set of edge-disjoint copies of $T$ in $G$ that cover the edge set of $G$. Graham and H\"aggkvist (1989) conjectured that any $2\ell$-regular graph $G$ admits a $T$-decomposition if $T$ is a tree with $\ell$ edges ...

A general model for analysis of linear and hyperbolic enzyme inhibition mechanisms

open access: yesFEBS Open Bio, EarlyView.
We developed a general enzyme kinetic model that integrates these six basic inhibition mechanism onto a single one. From this model, we deduced a general enzyme kinetic equation that through modulation of simple parameters, γ (the relative inhibitor affinity for two binding sites) and β (the reactivity of the enzyme–substrate–inhibitor complex), is ...

Microhabitat partitioning of <em>Apodemus flavicollis</em> and <em>Myodes glareolus</em> in the sub-montane Alps: a preliminary assessment

open access: yesHystrix, the Italian Journal of Mammalogy, 2011
Interspecific competition can cause partitioning in habitat use by sympatric species. This study gives a preliminary contribution to the understanding of microhabitat partitioning of <em>Apodemus flavicollis</em> and <em>Myodes ...

Thrombolytic proteins profiling: High‐throughput activity, selectivity, and resistance assays

open access: yesFEBS Open Bio, EarlyView.
We present optimized biochemical protocols for evaluating thrombolytic proteins, enabling rapid and robust screening of enzymatic activity, inhibition resistance, and fibrin affinity, stimulation, and selectivity. The outcome translates to key clinical indicators such as biological half‐life and bleeding risk. These assays streamline the development of

Estimating Percent Residue Cover Using the Line-Transect Method [PDF]

open access: yes, 2009
Leaving crop residue on the soil surface is one of the easiest and most cost-effective methods of reducing soil erosion. Research in Nebraska and other midwestern states has shown that leaving as little as 20 percent of the soil surface covered with crop
