DC-SIGN mediated internalisation of glycosylated extracellular vesicles from Schistosoma mansoni increases activation of monocyte-derived dendritic cells

open access: yesJournal of Extracellular Vesicles, 2020
Helminths like Schistosoma mansoni release excretory/secretory (E/S) products that modulate host immunity to enable infection. Extracellular vesicles (EVs) are among these E/S products, yet molecular mechanisms and functionality of S.

Purification of a fragment obtained by autolysis of a PIIIb-SVMP from Bothrops alternatus venom [PDF]

open access: yes, 2018
Snake Venom Metalloproteinases (SVMPs) represent 43.1% of the components in Bothrops alternatus venom and play an important role in envenomation. Disintegrins and disintegrin-like domains are released by proteolytic processing of PII and PIII classes of ...

A SVD based scheme for post processing of DCT coded images [PDF]

open access: yes, 2009
In block discrete cosine transform (DCT) based image compression the blocking artifacts are the main cause of degradation, especially at higher compression ratio.

Power loss investigation in HVDC for cascaded H-bridge multilevel inverters (CHB-MLI) [PDF]

open access: yes, 2015
In the last decade, the use of voltage-source multilevel inverters in industrial and utility power applications has been increased significantly mainly due to the many advantages of multilevel inverters, compared to conventional two level inverters ...

Programmable Gain Amplifiers with DC Suppression and Low Output Offset for Bioelectric Sensors

open access: yesSensors, 2013
DC-offset and DC-suppression are key parameters in bioelectric amplifiers. However, specific DC analyses are not often explained. Several factors influence the DC-budget: the programmable gain, the programmable cut-off frequencies for high pass filtering

Fault blocking converters for HVDC transmission : a transient behaviour comparison [PDF]

open access: yes, 2018
A thorough comparison of the transient behaviours of two state-of-the-art converters suitable for HVDC transmission is presented. The Alternate Arm and Mixed-Cell Modular Multilevel Converter topologies both have DC fault blocking capability and are ...

Improved Handover Through Dual Connectivity in 5G mmWave Mobile Networks

open access: yes, 2017
The millimeter wave (mmWave) bands offer the possibility of orders of magnitude greater throughput for fifth generation (5G) cellular systems. However, since mmWave signals are highly susceptible to blockage, channel quality on any one mmWave link can be

Converter non‐blocking DC fault ride‐through and system fast restoration arrangements in R‐L SFCL‐equipped MMC‐M2TDC system

open access: yesIET Generation, Transmission & Distribution
Equipping a DC‐type superconducting fault current limiter (SFCL) in a modular multilevel converter‐based multi‐terminal DC (MMC‐M2TDC) system has the potential to reorganize the protection control arrangements during the DC‐side short‐circuit fault. This

A new single-stage current source inverter for photovoltaic and fuel cell applications using reverse blocking IGBTs [PDF]

open access: yes
Renewable energy sources such as photovoltaics (PVs) or fuel cells (FCs) are not fitted for direct power grid connection because they deliver DC voltage and current. This is why a power electronic interface is needed, consisting usually of a current-mode
