Ahn, Anne Catherine (author), Schuurmans, J. Merijn (author), Sorokin, Dimitry Y. (author), Muyzer, Gerard (author)Haloalkaliphilic chemolithoautotrophic sulfur-oxidizing bacteria belonging to the genus Thioalkalivibrio are highly abundant in microbial communities found in soda lakes and dominant in full-scale bioreactors removing sulfide from industrial waste gases. Despite certain soda lakes being remote and unaffected by anthropogenic activities,...journal article 2023

Sung Lee, Kee (author), Ahn, Hyeonji (author), Won Lee, Gye (author), Sloof, W.G. (author)Although the crack-healing capacity of Ti<sub>2</sub>AlC ceramics has been sufficiently studied, the ability of Ti<sub>2</sub>AlC to self-heal large-scale damage, such as foreign object damage (FOD), remains unknown. This paper investigates the self-healing ability of Ti<sub>2</sub>AlC ceramics with large-scale damage (∼1000 μm in diameter)....journal article 2023

Nagalur Subraveti, H.H.S. (author), Srivastava, Anupam (author), Ahn, Soyoung (author), Knoop, V.L. (author), van Arem, B. (author)This paper presents a novel approach to improve traffic throughput near diverge and weave bottlenecks in mixed traffic with human-driven vehicles (HDVs) and connected automated vehicles (CAVs). This is done by the strategic assignment of CAVs across lanes. The main principle is to induce strategic and necessary lane changes (LCs) (by CAVs and...journal article 2021

(author), Lee, Su Jin (author), Cho, Jee Eun (author), Patil, Vinod Vikas (author), Dumbrepatil, Arti Baban (author), Song, Hyung Nam (author), Ahn, Woo Chan (author), Joo, C. (author)The Pseudomonas putida phenol-responsive regulator DmpR is a bacterial enhancer binding protein (bEBP) from the AAA<sup>+</sup> ATPase family. Even though it was discovered more than two decades ago and has been widely used for aromatic hydrocarbon sensing, the activation mechanism of DmpR has remained elusive. Here, we show that phenol-bound...journal article 2020

(author), Muyzer, Gerard (author)The genus Thioalkalivibrio includes haloalkaliphilic chemolithoautotrophic sulfur-oxidizing bacteria isolated from various soda lakes worldwide. Some of these lakes possess in addition to their extreme haloalkaline environment also other harsh conditions, to which Thioalkalivibrio needs to adapt. An example is arsenic in soda lakes in eastern...journal article 2019

(author), Kim, Doseok (author)At the core of homologous DNA repair, RecA catalyzes the strand exchange reaction. This process is initiated by a RecA loading protein, which nucleates clusters of RecA proteins on single-stranded DNA. Each cluster grows to cover the single-stranded DNA but may leave 1- to 2-nucleotide (nt) gaps between the clusters due to three different...journal article 2017

Kim, K.J. (author), Blanter, Y.M. (author), Ahn, K.H. (author)We investigate electric and magnetic properties of graphene with rotationally symmetric strain. The strain generates a large pseudomagnetic field with alternating sign in space, which forms a strongly confined quantum dot connected to six chiral channels. The orbital magnetism, degeneracy, and channel opening can be understood from the interplay...journal article 2011

(author)We performed terahertz near-field experiments on single rectangular holes with various lengths grown on an electro-optic crystal substrate with ?/100 resolution. We find that the near-field amplitude becomes proportionally larger as the rectangle becomes narrower, strongly suggesting that a constant energy passes through even for a very narrow...journal article 2008
