Determination of secondary metabolite in galls of some cynipid wasps (Hymenoptera: Cynipidae) and characterization of the phenolic compound

open access: yesInternational Journal of Secondary Metabolite, 2023
The galls of cynipid species (Hymenoptera: Cynipidae) have been used since ancient times as an important source of bioactive compounds. Many researchers have evaluated the medicinal potential of some cynipid galls and found that these galls have numerous

Stress and defense responses in plant secondary metabolites production

open access: yesBiological Research, 2019
In the growth condition(s) of plants, numerous secondary metabolites (SMs) are produced by them to serve variety of cellular functions essential for physiological processes, and recent increasing evidences have implicated stress and defense response ...

BeStSel: a web server for accurate protein secondary structure prediction and fold recognition from the circular dichroism spectra

open access: yesNucleic Acids Res., 2018
Circular dichroism (CD) spectroscopy is a widely used method to study the protein secondary structure. However, for decades, the general opinion was that the correct estimation of β-sheet content is challenging because of the large spectral and ...

A note on the Fourier coefficients of a Cohen-Eisenstein series

open access: yes, 2016
We prove a formula for the coefficients of a weight $3/2$ Cohen-Eisenstein series of square-free level $N$. This formula generalizes a result of Gross and in particular, it proves a conjecture of Quattrini. Let $l$ be an odd prime number.

Cleavage of DFNA5 by caspase-3 during apoptosis mediates progression to secondary necrotic/pyroptotic cell death

open access: yesNature Communications, 2017
Apoptosis is a genetically regulated cell suicide programme mediated by activation of the effector caspases 3, 6 and 7. If apoptotic cells are not scavenged, they progress to a lytic and inflammatory phase called secondary necrosis.

Irreducibility of Polynomials over Global Fields is Diophantine

open access: yes, 2017
Given a global field $K$ and a positive integer $n$, we present a diophantine criterion for a polynomial in one variable of degree $n$ over $K$ not to have any root in $K$.

Biodiversity recovery of Neotropical secondary forests

open access: yesScience Advances, 2019
Tropical secondary forests recover quickly (decades) in tree species richness but slowly (centuries) in species composition. Old-growth tropical forests harbor an immense diversity of tree species but are rapidly being cleared, while secondary forests ...

Deuring for the People: Supersingular Elliptic Curves with Prescribed Endomorphism Ring in General Characteristic [PDF]

open access: yes, 2023
Constructing a supersingular elliptic curve whose endomorphism ring is isomorphic to a given quaternion maximal order (one direction of the Deuring correspondence) is known to be polynomial-time assuming the generalized Riemann hypothesis [KLPT14; Wes21],

Anti-tori in square complex groups

open access: yes, 2004
An anti-torus is a subgroup $$ in the fundamental group of a compact non-positively curved space $X$, acting in a specific way on the universal covering space $\tilde{X}$ such that $a$ and $b$ do not have any commuting non-trivial powers.
