Daleu, C. L. (author), Plant, R. S. (author), Woolnough, S. J. (author), Sessions, S. (author), Herman, M. J. (author), Sobel, A. (author), Wang, S. (author), Kim, D. (author), Cheng, A. (author), Bellon, G. (author), Peyrille, P. (author), Ferry, F. (author), Siebesma, A.P. (author), Van Ulft, L. (author)

As part of an international intercomparison project, a set of single-column models (SCMs) and cloud-resolving models (CRMs) are run under the weak-temperature gradient (WTG) method and the damped gravity wave (DGW) method. For each model, the implementation of the WTG or DGW method involves a simulated column which is coupled to a reference...

Temperature dependence of atomic vibrations in mono-layer graphene

Allen, C.S. (author), Liberti, E. (author), Kim, J.S. (author), Xu, Q. (author), Fan, Y. (author), He, K. (author), Robertson, A.W. (author), Zandbergen, H.W. (author), Warner, J.H. (author), Kirkland, A.I. (author)

We have measured the mean square amplitude of both in- and out-of-plane lattice vibrations for mono-layer graphene at temperatures ranging from ?100 K to 1300?K. The amplitude of lattice vibrations was calculated from data extracted from selected area electron diffraction patterns recorded across a known temperature range with over 80...

TUT7 controls the fate of precursor microRNAs by using three different uridylation mechanisms

Kim, B. (author), Ha, M. (author), Loeff, L. (author), Chang, H. (author), Simanshu, D.K. (author), Li, S. (author), Fareh, M. (author), Patel, D.J. (author), Joo, C. (author), Kim, V.N. (author)

Terminal uridylyl transferases (TUTs) function as integral regulators of microRNA (miRNA) biogenesis. Using biochemistry, single-molecule, and deep sequencing techniques, we here investigate the mechanism by which human TUT7 (also known as ZCCHC6) recognizes and uridylates precursor miRNAs (pre-miRNAs) in the absence of Lin28. We find that the...

Distinct mechanisms regulating mechanical force-induced Ca2+ signals at the plasma membrane and the ER in human MSCs

Kim, T.J. (author), Joo, C. (author), Seong, J. (author), Vafabakhsh, R. (author), Botvinick, E.L. (author), Berns, M.W. (author), Palmer, A.E. (author), Wang, N. (author), Ha, T. (author), Jakobsson, E. (author), Sun, J. (author), Wang, Y. (author)

It is unclear that how subcellular organelles respond to external mechanical stimuli. Here, we investigated the molecular mechanisms by which mechanical force regulates Ca2+ signaling at endoplasmic reticulum (ER) in human mesenchymal stem cells. Without extracellular Ca2+, ER Ca2+ release is the source of intracellular Ca2+ oscillations induced...

Dynamic Growth and Shrinkage Govern the pH Dependence of RecA Filament Stability

Kim, S.H. (author), Park, J. (author), Joo, C. (author), Kim, D. (author), Ha, T. (author)

RecA proteins form a long stable filament on a single-stranded DNA and catalyze strand exchange reaction. The stability of RecA filament changes dramatically with pH, yet its detailed mechanism is not known. Here, using a single molecule assay, we determined the binding and dissociation rates of RecA monomers at the filament ends at various pH....

Moving droplets: The measurement of contact lines

Poelma, C. (author), Franken, M.J.Z. (author), Kim, H. (author), Westerweel, J. (author)

Contact lines are the locations where a gas, liquid and a solid meet. From everyday experience we know that such contact lines can be mobile, for example in the case of a water droplet sliding over a glass surface. However, the continuum description of the flow towards or away from a contact line implies that the forces diverge as one approaches...

Velocity and temperature fields measurement of natural circulation flow inside a pool using PIV and PLIF technique

Kim, S. (author), Kim, D.E. (author), Euh, D.J. (author)

Thermal stratification is encountered in large pool of water increasingly being used as heat sink in new generation of advanced reactors. These large pools at near atmospheric pressure provide a heat sink for heat removal from the reactor or steam generator, and the containment by natural circulation as well as a source of water for core cooling...

Tomographic PIV measurement of flow in a complex geometry of nasal cavity

Im, S. (author), Heo, G.E. (author), Sung, H.J. (author), Kim, S.K. (author)

Flow inside a scaled model of nasal cavity was measured by tomographic PIV. The model was constructed with transparent silicon. A refractive index of working fluid was matched to the model index by mixing glycerol and water. Four cameras and double pulse laser system were used for tomographic PIV. To obtain high SNR, red fluorescence particles...

Lee, C.H. (author), Kim, D.Y. (author), Kim, H.D. (author), Kim, K.C. (author)

Dynamic behaviour and heat transfer characteristics of impinging droplets on a hot surface were studied experimentally. De-ionized water droplet was made through a 31G injection needle and the droplet size was 2 mm. A sapphire plate was heated up to 300ºC by a hotplate. A high speed camera was used for visualization, and the frame rate was 4000...
