Analysis of Hydraulic Characteristics According to the Cross-Section Changes in Submerged Rigid Vegetation

open access: yes한국해양공학회지, 2022
Recently, not only Korea but also the world has been suffering from problems related to coastal erosion. The hard defense method has been primarily used as a countermeasure against erosion.

A basic lock-in amplifier experiment for the undergraduate laboratory [PDF]

open access: yes, 2003
We describe a basic experiment for the undergraduate laboratory that demonstrates aspects of both, the science and the art of precision electronic measurements. The essence of the experiment is to measure the resistance of a small length of brass-wire to

Research note on an experimental approach to the intrinsic motivations of corruption [PDF]

open access: yesThe Journal of Philosophical Economics, 2013
Even though most of the causes of corruption are easily identifiable at the macro level, there is considerable disagreement when it comes to the intrinsic motivations leading people to engage in this activity. The present paper tries to shed light on the

Proteomic profiling of the human amniotic stem cell-highly abundant secreted proteins [PDF]

open access: yesPeerJ
Amnion-derived stem cells exhibit several significant advantages, including low immunogenicity, anti-inflammatory, anti-fibrotic, and angiogenic properties, which have garnered considerable attention as a potential source for cell therapy.

Interferometric measurement of the resonant absorption and refractive index in rubidium gas [PDF]

open access: yes, 2006
We present a laboratory demonstration of the Kramers-Kronig relation between the resonant absorption and refractive index in rubidium gas. Our experiment uses a rubidium vapor cell in one arm of a simple Mach-Zehnder interferometer.

Core Payload of the Space Gravitational Wave Observatory: Inertial Sensor and Its Critical Technologies

open access: yesSensors
Since Einstein’s prediction regarding the existence of gravitational waves was directly verified by the ground-based detector Advanced LIGO, research on gravitational wave detection has garnered increasing attention.

Impact of Thin-Walled Projectiles with Concrete Targets

open access: yesShock and Vibration, 1995
An experimental program to determine the response of thin-walled steel projectiles to the impact with concrete targets was recently conducted. The projectiles were fired against 41-MPa concrete targets at an impact velocity of 290 m/s.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Does Party Polarization Affect the Electoral Prospects of a New Centrist Candidate?

open access: yesGames, 2022
Does party polarization affect the electoral prospects of a new centrist candidate? The paper investigates this question in the context of a laboratory experiment where a centrist candidate is added to the race between a left candidate and a right ...

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
