Abstract Perovskite oxide-based heterostructures exhibit a range of exotic physical properties such as two-dimensional superconductivity, interface magnetism, tunable Kondo effect, and spin-orbit coupling. Here, the magnetotransport Al2O3/SrTiO3 Al2O3/KTaO3 are studied. Both effect coupling-induced weak antilocalization (WAL) observed at low temperatures. By analyzing WAL curves, spin relaxation time is extracted. Surprisingly, extracted unexpectedly decreases on increasing temperature in...
This research aims to design and validate a machine learning model predict the probability of urinary tract infections within 90 days post-urostomy in bladder cancer patients. Clinical follow-up information from 317 patients who had urostomy procedures at First Affiliated Hospital Shanxi Medical University (May 2018–May 2024) were analyzed. The dataset partitioned into training testing sets, feature selection was executed via Least Absolute Shrinkage Selection Operator regression technique....
We study the magnetotransport properties of monolayer graphene grown on SiC substrates. At low magnetic fields, a parabolic magnetoresistance (MR) is observed. With increasing field, however, this MR changed to linear field dependence that does not show signs saturation for fields up 9 T. fixed value decreases with temperature, its as large 80% under T at room temperature. Furthermore, Hall mobility found be suppressed when sample annealed 390 K helium atmosphere, suppression causing...
An unsaturated linear magnetoresistance (LMR) has attracted wide attention because of potential applications and fundamental interest. By controlling growth temperature, we realized a metal-to-insulator transition in ${\mathrm{Al}}_{2}{\mathrm{O}}_{3}$/$\mathrm{SrTi}{\mathrm{O}}_{3}$ heterostructures. The LMR is observed metallic samples with electron mobility varying over three orders magnitude. cannot be explained by the guiding center diffusion model even very high mobility. slope...
We report on the magnetotransport properties of 100 nm wide parabolic quantum wells and observe an enhancement Hall resistance in one sample but not other. This phenomenon is likely related to effective thickness electronic slab. also a negative magnetoresistance originating from electron-electron interactions when only subband occupied samples. The interaction correction Drude conductivity extracted using two methods. find that increases with increasing tilted angle, for which possible...

Layered transition metal chalcogenides have stimulated wide research interest due to their many exotic physical properties. In this paper, we study the magnetotransport properties of exfoliated nodal-line semimetal $\mathrm{TaNiT}{\mathrm{e}}_{5}$. A giant positive magnetoresistance (MR) is observed when current parallel crystallographic $c$ axis, while it strongly diminished flows along $a$ axis. The MR gradually suppressed either on reducing thickness nanoflake or increasing temperature....
