tobac v1.5: introducing fast 3D tracking, splits and mergers, and other enhancements for identifying and analysing meteorological phenomena by Sokolowsky, GA, Freeman, SW, Jones, WK, Kukulies, J, Senf, F, Marinescu, PJ, Heikenfeld, M, Brunner, KN, Bruning, EC, Collis, SM, Jackson, RC, Leung, GR, Pfeifer, N, Raut, BA, Saleeby, SM, Stier, P, van den Heever, SC

“…A number of scientific improvements (three spatial dimensions, splits and mergers of features, an internal spectral filtering tool) and procedural enhancements (increased computational efficiency, internal regridding of data, and treatments for periodic boundary conditions) have been included in tobac as a part of the tobac v1.5 update. These improvements have made tobac one of the most robust, powerful, and flexible identification and tracking tools in our field to date and expand its potential use in other fields. …”

Regulation of coronavirus gene expression by the 5'-untranslated region. by Guo, Huiling.

“…The regulatory properties of the 5’-untranslated region (5’-UTR) of the avian infectious bronchitis virus (IBV) were investigated through designing of plasmids which contained different mutations within the 5’-UTR: full-length (pUTR-wt), 362- nucleotides (nts) deleted (pUTR-362del) and stem-loop 1 (SL1) disrupted (pSL1- dsmut). …”

Spin-orbit torque magnetization switching in Co/Pt multilayers for multistate memory and logic devices by Lim, Gerard Joseph

“…It has proven to be a serious contender in emerging memory technology due to its intrinsic non-volatility, low power dissipation, and high speed. The spin degree of freedom further opens opportunities that exploit its ultrafast dynamics and spin transport. …”

Programmable spin–orbit-torque logic device with integrated bipolar bias field for chirality control by Lim, Gerard Joseph, Chua Daniel, Gan Weiliang, Murapaka Chandrasekhar, Lew Wen Siang

“…While several field-free spin–orbit torque (SOT)-driven logic devices have been proposed, their operation typically requires additional initialization or reset pulses, the exchange-coupled canted spins reduce both anomalous Hall sign-to-noise ratio as well as thermal stability of the ferromagnetic layer, and device-to-device variation in exchange coupling strength is expected. …”

Janus particle preparation through UV-induced partial photodegradation of spin-coated particle films by Tan, Jasmine Si Jia, Wong, Chong Hui, Chen, Zhong

“…Photocatalytic titanium dioxide particles prefunctionalized with a surface coating were assembled as particle films via spin-coating on a substrate. The particle films were placed directly under an ultraviolet light source, which induced the photodegradation of the surface coating only on the particle surfaces exposed to the light. …”
