Neocotylidia gen. nov. (Hymenochaetales, Basidiomycota) Segregated from Cotylidia Based on Morphological, Phylogenetic, and Ecological Evidence

open access: yesJournal of Fungi
Taxonomic and phylogenetic studies of Cotylidia (Hymenochaetales, Basidiomycota) were performed. A phylogenetic estimate based on six genetic markers revealed that Cotylidia in the current sense includes species belonging to three distantly related ...

Taking creative license: It's not an easy thing meeting your maker [PDF]

open access: yes, 2001
Creators do not just 'create' or 'act' -- they are privileged agents, points of origin, sources of innovation and transformation. Within religious systems, creators can exist in an extra-discursive real beyond nature and culture, functioning as the ...

Resonance production in central pp collisions at the CERN Omega Spectrometer [PDF]

open access: yes, 2000
A study of resonance production in central pp collisions is presented as a function of several kinematical variables. In particular the difference in the transverse momentum (dPT) of the exchanged particles shows that undisputed qqbar mesons are ...

Phylogeny and species diversity of Armillaria in China based on morphological, mating test, and GCPSR criteria

open access: yesMycology
More than 600 Chinese specimens of Armillaria were identified by mating tests, Genealogical Concordance Phylogenetic Species Recognition (GCPSR), and comparison of morphological characteristics. Sixteen Chinese Biological Species (CBS) of Armillaria were

Determination of the Higgs boson spin with a linear e+e- collider [PDF]

open access: yes, 2001
The energy dependence of the production cross section of a light Higgs boson is studied at threshold and compared to the expectations of several spin assumptions.

Single $W_R$ Production in $e^-e^-$ Collisions at the NLC

open access: yes, 1994
Single $W_R$ production in $e^-e^-$ collisions at the NLC can be used to probe the Majorana nature of the heavy neutrinos present in the Left-Right Symmetric Model below the kinematic threshold for their direct production. For colliders in the $\sqrt {s}=

The Role of Crop Production in the Forest Landscape Restoration Approach—Assessing the Potential Benefits of Meeting the Bonn Challenge

open access: yesFrontiers in Sustainable Food Systems, 2020
Existing approaches and methodologies that investigate effects of land degradation on food security vary greatly. Although a relatively rich body of literature that investigates localized experiences, geophysical, and socioeconomic drivers of land ...

Intact Forest in Selective Logging Landscapes in the Tropics

open access: yesFrontiers in Forests and Global Change, 2019
The selective logging that characterizes most timber extraction operations in the tropics leaves large patches of logging blocks (i. e., areas allocated for harvesting) intact, with no direct impacts of the harvest.

Production Under Uncertainty: A Simulation Study [PDF]

open access: yes
In this article we model production technology in a state-contingent framework. Our model analyzes production under uncertainty without regard to the nature of producer risk preferences. In our model producers?

Quantifying Entanglement Production of Quantum Operations

open access: yes, 2003
The problem of entanglement produced by an arbitrary operator is formulated and a related measure of entanglement production is introduced. This measure of entanglement production satisfies all properties natural for such a characteristic.
