Harmonizing sound and light: X-ray imaging unveils acoustic signatures of stochastic inter-regime instabilities during laser melting

open access: yesNature Communications, 2023
Laser powder bed fusion (LPBF) is a metal additive manufacturing technique involving complex interplays between vapor, liquid, and solid phases. Despite LPBF’s advantageous capabilities compared to conventional manufacturing methods, the underlying ...

Effect of Oil Prices on Exchange Rate Movements in Korea and Japan Using Markov Regime-Switching Models

open access: yesEnergies, 2020
We examined the effects of oil prices along with fundamental economic variables on exchange rate movements in the Korean and Japanese foreign exchange markets, using two-regime Markov Regime Switching Models (MRSMs) over the period from January 1991 to ...

Extended theory of the Taylor problem in the plasmoid-unstable regime [PDF]

open access: yesPhysics of Plasmas, 2015
A fundamental problem of forced magnetic reconnection has been solved taking into account the plasmoid instability of thin reconnecting current sheets. In this problem, the reconnection is driven by a small amplitude boundary perturbation in a tearing-stable slab plasma equilibrium.

Unified Friction Formulation from Laminar to Fully Rough Turbulent Flow

open access: yesApplied Sciences, 2018
This paper provides a new unified formula for Newtonian fluids valid for all pipe flow regimes from laminar to fully rough turbulent flow. This includes laminar flow; the unstable sharp jump from laminar to turbulent flow; and all types of turbulent ...

Complex dynamics near extinction in a predator-prey model with ratio dependence and Holling type III functional response

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
In this paper, we analyze a recently proposed predator-prey model with ratio dependence and Holling type III functional response, with particular emphasis on the dynamics close to extinction.

The stable and unstable accretion regimes: Implications for the stellar rotation

open access: yes, 2023
In this talk, I will present the outcome of three-dimensional simulations studying the interaction between a magnetized solar-mass protostar and its surrounding accretion disk. The standard picture of magnetospheric accretion suggests that the disk gas reaches the stellar surface through accretion funnels or curtains, the so-called stable accretion ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Trends in Deforestation as a Response to Management Regimes and Policy Intervention in the Hindu Kush Himalaya of Pakistan

open access: yesFrontiers in Environmental Science, 2022
Based on the annual rate of deforestation as a forest conservation outcome, this study evaluated how effective is the existing forest management regime in controlling deforestation in the study area.
