Multiple Key Hosts and Network Structure Shape Viral Prevalence Across Multispecies Communities of Bees

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
This study develops a quantitative framework that integrates field data, epidemiological models, simulations, and Bayesian inference to identify key viral hosts in multispecies bee communities. By estimating species‐specific R0 values from flower‐visitor networks and viral screening, we show that honeybees, as well as other wild bees, can drive the ...

Preparation and Characterization of Oil Palm Leaf Fiber/Polypropylene/Epolene® E-43 Composite

open access: yesBioResources, 2014
Oil palm leaf fiber was used as a reinforcement material for the preparation of polypropylene composite. First, the influence of fiber loading on the mechanical and thermal characteristics of the composite was investigated.

On the fundamental group of the complement of a complex hyperplane arrangement

open access: yes, 2015
We construct two combinatorially equivalent line arrangements in the complex projective plane such that the fundamental groups of their complements are not isomorphic.

Impact of Variation in APOE on Rheumatoid Arthritis, Psoriasis, and Psoriatic Arthritis: Sequencing and Genotyping in General Population Cohorts

open access: yesACR Open Rheumatology, Volume 8, Issue 1, January 2026.
Objective Emerging evidence suggests that apolipoprotein E (apoE) may be involved in the immune system and diseases driven by chronic inflammation. The impact of the full range of structural genetic variation in APOE for risk of rheumatoid arthritis, psoriasis, and psoriatic arthritis in the general population is not known.

Automatic Construction of Explicit R Matrices for the One-Parameter Families of Irreducible Typical Highest Weight (0|\alpha) Representations of U_q[gl(m|n)]

open access: yes, 2001
We detail the automatic construction of R matrices corresponding to (the tensor products of) the (0|\alpha) families of highest-weight representations of the quantum superalgebras U_q[gl(m|n)].

Semi-classical twists for sl(3) and sl(4) boundary r-matrices of Cremmer-Gervais type [PDF]

open access: yes, 2005
We obtain explicit formulas for the semi-classical twists deforming the coalgebraic structure of U(sl(3)) and U(sl(4)). In rank 2 and 3 the corresponding universal R-matrices quantize the boundary r-matrices of Cremmer-Gervais type defining Lie Frobenius
