An innovative method to assess specific charge, drilling and blasting costs considering critical factors of rock mass properties, fragment size and blasthole parameters

open access: yesResults in Engineering
The specific charge has been given as a function of the blastability index (BI) only in previous research, whereas fragment size is one of the attractive blasting results. The impacts of combination of the important factors such as fragment size, in-situ

Fragmentation of the 4He2 dimer with the emission of three or four electrons by fast highly charged projectiles

open access: yesFrontiers in Physics, 2023
We investigate the fragmentation of the helium dimer, 4He2, into He2+ + He+ and He2+ + He2+ ions in collisions with fast highly charged projectiles. We discuss the main physical mechanisms driving these processes.

Predictive Modeling of Ungulate–Vehicle Collision in the Republic of Korea

open access: yesBiology, 2023
Animal–vehicle collisions (AVC) threaten animals as well as human life and property. AVC with ungulates, called ungulate–vehicle collision (UVC), often seriously endangers human safety because of the considerable body size of ungulates.

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

open access: yesFEBS 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

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

open access: yesFEBS 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 ...
