트위스트가 있는 계층화된 그래핀은 2D에서 고유한 양자 구속 효과를 표시합니다.

Understanding how electrons move in 2-D layered material systems could lead to advances in quantum computing and communication. Scientists studying two different configurations of bilayer graphene—the two-dimensional (2-D), atom-thin form of carbon—have detected electronic and optical interlayer resonances. In these resonant states, electrons bounce back and forth between the two atomic planes in the 2-D…

TraCe-seq를 사용한 암 약물 반응의 기초가 되는 전사 프로그램 식별

AbstractGenetic and non-genetic heterogeneity within cancer cell populations represent major challenges to anticancer therapies. We currently lack robust methods to determine how preexisting and adaptive features affect cellular responses to therapies. Here, by conducting clonal fitness mapping and transcriptional characterization using expressed barcodes and single-cell RNA sequencing (scRNA-seq), we have developed tracking differential clonal response…

This dance, called dynamic voltage and frequency scaling (DVFS), happens continually in the processor, called a system-on-chip (SoC), that runs your phone and your laptop as well as in the servers that back them. It’s all done in an effort to balance computational performance with power consumption, something that’s particularly challenging for smartphones. The circuits…
