Joint estimation and detection method based on turbo equalization framework and VAMP [PDF]

open access: yesITM Web of Conferences, 2022
In this letter, we consider the single-carrier frequency domain equalization (SC-FDE) system, and propose a low-complexity joint symbol detection and channel estimation algorithm based on the recently proposed vector approximate message passing (VAMP ...

Performance Analysis and Improvement for VAMP Soft Frequency-Domain Equalizers

open access: yesIEEE Access, 2019
The vector approximate message passing (VAMP) soft frequency-domain equalizer (SFDE) has been proposed for turbo equalization. It consists of an inner soft equalizer (ISE) and an inner soft slicer (ISS), which iteratively exchange block-wise extrinsic ...

Loss of AP-3 function affects spontaneous and evoked release at hippocampal mossy fiber synapses [PDF]

open access: yes, 2006
Synaptic vesicle (SV) exocytosis mediating neurotransmitter release occurs spontaneously at low intraterminal calcium concentrations and is stimulated by a rise in intracellular calcium.

Identification of the SNARE complex that mediates the fusion of multivesicular bodies with the plasma membrane in exosome secretion

open access: yesJournal of Extracellular Vesicles, 2023
Exosomes play crucial roles in local and distant cellular communication and are involved in various physiological and pathological processes. Tumour‐derived exosomes are pivotal to tumorigenesis, but the precise mechanisms underlying their secretion ...

Sposobnost biohidrogenacije linolne kisline pri vampni bakteriji Pseudobutyrivibrio xylanivorans Mz5T

open access: yesActa Agriculturae Slovenica, 2006
Konjugirane linolne kisline (CLA) so skupina pozicijskih in geometrijskih izomer oktadekadienojske kisline (18:2) in imajo vrsto ugodnih učinkov pri ljudeh in ûivalih. Glavni tvorci CLA so vampne bakterije, predvsem iz rodu Butyrivibrio.

Potek fermentacije škroba ob dodatku različnih vrst taninov

open access: yesActa Agriculturae Slovenica, 2007
Proučevali smo vpliv vrste in koncentracije različnih taninskih izvlečkov na kinetiko in vitro fermentacije škroba v vampnem soku. K škrobu smo dodali tri taninske izvlečke: kostanjev tanin (F75), kebračo tanin (QUE) in taninsko kislino (TAK) v različnih

Razgradnja ksilana z različnimi ksilanazami vampne bakterije Pseudobutyrivibrio xylanivorans Mz5T

open access: yesActa Agriculturae Slovenica, 2004
Uporaba ksilanaz kot krmnih dodatkov je pri monogastričnih živalih zelo obetavna, saj so njihov ugoden učinek na zdravstveno stanje in prirast živali potrdile številne raziskave. Pred kratkim je bila opisana nova vrsta vampne bakterije P.

Osamitev in opis vampnih spirohet

open access: yesActa Agriculturae Slovenica, 2000
Iz vzorca vampne vsebine smo osamili tri seve vampnih spirohet. Morfologijo osamljenih sevov smo opazovali s fazno kontrastno in epifluorescentno mikroskopijo ter jih opisali s hitrimi biokemijskimi preskusi (API 50CH) in molekulsko biološkimi ...

Minimally Invasive Monitoring of Chronic Central Venous Catheter Patency in Mice Using Digital Subtraction Angiography (DSA). [PDF]

open access: yesPLoS ONE, 2015
Repetitive administration of medication or contrast agents is frequently performed in mice. The introduction of vascular access mini-ports (VAMP) for mice allows long-term vascular catheterization, hereby eliminating the need for repeated vessel puncture.
