Brazilian Mangroves: Blue Carbon Hotspots of National and Global Relevance to Natural Climate Solutions

open access: yesFrontiers in Forests and Global Change, 2022
Mangroves are known for large carbon stocks and high sequestration rates in biomass and soils, making these intertidal wetlands a cost-effective strategy for some nations to compensate for a portion of their carbon dioxide (CO2) emissions.

Vortex avalanches and magnetic flux fragmentation in superconductors

open access: yes, 2001
We report results of numerical simulations of non isothermal dendritic flux penetration in type-II superconductors. We propose a generic mechanism of dynamic branching of a propagating hotspot of a flux flow/normal state triggered by a local heat pulse ...

Collimation of extragalactic radio jets in compact steep spectrum and larger sources [PDF]

open access: yes, 1999
We study the collimation of radio jets in the high-luminosity Fanaroff-Riley class II sources by examining the dependence of the sizes of hotspots and knots in the radio jets on the overall size of the objects for a sample of compact steep-spectrum or ...

Hotspot advance speed - hotspot size/core-hotspot distance relation

open access: yesRwanda Journal, 2016
We examined the evolution of extragalactic radio sources using the observed corehotspot distance and hotspot size. Analysis indicates a fairly strong positive correlation in the ratio of core-hotspot distance to hotspot size between that of the approaching arm and the receding arm with a correlation coefficient of r ~ 0.7.

Hotspot Advance Speed - Hotspot Size/Core-Hotspot Length Relation

open access: yesInternational Letters of Chemistry, Physics and Astronomy, 2015
We examined the evolution of extragalactic radio sources using the observed core-hotspot length and hotspot size. Analysis indicates a fairly strong positive correlation in the ratio of core-hotspot length to hotspot size between that of the approaching arm and the receding arm with a correlation coefficient of r ~ 0.7.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

open access: yesFEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Epidemiological features and spatial-temporal clustering of visceral leishmaniasis in mainland China from 2019 to 2021

open access: yesFrontiers in Microbiology, 2022
BackgroundVisceral leishmaniasis (VL) is a serious vector-borne disease in central and western China. In recent years, the number of VL cases increased gradually, particularly the mountain-type zoonotic visceral leishmaniasis (MT-ZVL).

Dynamics Inside the Radio and X-ray Cluster Cavities of Cygnus A and Similar FRII Sources

open access: yes, 2012
We describe approximate axisymmetric computations of the dynamical evolution of material inside radio lobes and X-ray cluster gas cavities in Fanaroff-Riley II sources such as Cygnus A.
