Diversity and Relative Abundance of Ichthyofauna in Manasbal Lake of the Kashmir Himalayas, India

open access: yesCroatian Journal of Fisheries, 2022
Diversity, abundance and distribution pattern of the fish fauna are important aspects that need to be considered in order to frame the conservation and management strategies in any water body.

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Mixed axion/neutralino cold dark matter in supersymmetric models

open access: yes, 2011
We consider supersymmetric (SUSY) models wherein the strong CP problem is solved by the Peccei-Quinn (PQ) mechanism with a concommitant axion/axino supermultiplet.

Exact theory of freeze out [PDF]

open access: yes, 2015
We show that the standard theory of thermal production and chemical decoupling of WIMPs is incomplete. The hypothesis that WIMPs are produced and decouple from a thermal bath implies that the rate equation the bath particles interacting with the WIMPs is

Archéologie de l’utopie

open access: yesKentron, 2008
The “Utopian propensity” by which men long for an ideal society where neither need nor struggle would occur, where even death is gentle, is noticeable in early Archaic Greek poetry.

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Non-perturbative Effect on Thermal Relic Abundance of Dark Matter

open access: yes, 2006
We point out that thermal relic abundance of the dark matter is strongly altered by a non-perturbative effect called the Sommerfeld enhancement, when constituent particles of the dark matter are non-singlet under the SU(2)_L gauge interaction and much ...

Recruitment, abundance, and predation on the blue mussel (Mytilus edulis) on northeastern estuarine rocky shores

open access: yesEcosphere, 2015
We report on patterns of abundance, recruitment, and predation on the blue mussel (Mytilus edulis) in three human‐dominated estuaries in the northeastern United States.

Predatory fish diets shift towards an invasive mullet in a traditional Hawaiian aquaculture system

open access: yesAquaculture, Fish and Fisheries, 2022
Traditional Hawaiian fishponds, called loko iʻa, are a low‐impact and culturally important aquaculture system that historically produced significant fish yields.

The Influence of Distance Between Oil Palm Plantations and Forest Ecosystems on Spider Diversity

open access: yesJournal of Applied Agricultural Science and Technology, 2023
Forest conversion to oil palm plantations forms a unique agroecosystem. Forests known as a source of biodiversity are bordered by oil palm plantations with low diversity.
