Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

The impact of land development on the distribution of road noise level on the surface of the upper wildlife crossings

Budownictwo i Architektura, 2014
The Environmental Protection concerns mainly the fauna, because the development of communication and the construction of new transport routes has been increasingly fragmenting the natural environment.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

New Approach to Determining Visibility Length on Passive Protected Level Railroad Crossings

Promet (Zagreb), 2012
The paper is based on the question whether the existing (legislation determined) method for determining the visibility length on passive protected level railroad crossings insures the relevant level of traffic safety. It has been recognised that using of

Object Detection at Level Crossing Using Deep Learning

Micromachines, 2020
Multiple projects within the rail industry across different regions have been initiated to address the issue of over-population. These expansion plans and upgrade of technologies increases the number of intersections, junctions, and level crossings.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Is it safe to cross? Identification of trains and their approach speed at level crossings [PDF]

, 2018
© 2017 Elsevier Ltd Improving the safety at passive rail crossings is an ongoing issue worldwide. These crossings have no active warning systems to assist drivers’ decision-making and are completely reliant on the road user perceiving the approach of a ...

Methodology for assessing the lighting of pedestrian crossings based on light intensity parameters

MATEC Web of Conferences, 2017
One of the possible preventive measures that could improve safety at crossings is to assess the state of illumination of the lighting installation located in the transition area for pedestrians. The City of Warsaw has undertaken to comprehensively assess

LEVEL CROSSING ACCIDENTS ANALYSIS IN ROMANIA [PDF]

Annals of the University of Petroşani. Mechanical Engineering, 2023
Level crossing accidents are one of the largest groups of fatal accidents and it is often useful to investigate them from a safety point of view in order to avoid their recurrence.
