Abstract Background High temperatures, particularly at night, decrease rice yield and quality. As high nighttime temperatures (HNTs) become increasingly frequent due to climate change, it is imperative develop crops that tolerate HNTs. DNA methylation may represent a potential avenue for HNT-tolerant strain development, as this mechanism regulates gene activity cellular phenotype in response adverse environmental conditions without changing the nucleotide sequence.

This brief presents a 54–68 GHz two-stage power amplifier (PA) with linearity and efficiency enhancement in 40 nm CMOS process. The first stage adopts current reuse cascaded common-source (CS) structure shunt RC feedback to maximize the gain minimize DC consumption boost efficiency, while second is cascode two built-in linearizers enhance much further. Based on proposed structure, fabricated PA exhibits measured output of 1-dB compression point, saturated power, added (PAE) AM-PM distortion...
This paper presents a low power injection-locked oscillator (ILO)-type clock and data recovery (CDR) in 40 nm CMOS. An efficient "phase reset" scheme is proposed to periodically realign the phase rising edge of data. The frequency information extracted by comparing after aligning using bang-bang detector (BBPD). Additionally, two-stage ring digitally controlled (ILDCO) employed provide four-phase quadrature significantly reduce consumption. Based on architecture, fabricated CDR consumes only...
This paper presents a dual-coupled single-ended (SE) receiver with crosstalk cancellation and signal reutilization (XTCR) technique in 28 nm CMOS process. The asymmetric-inductor SE to differential converter (S2D) is proposed eliminate the mismatch at its pseudo-differential outputs. conventional active extraction (AXTE) techniques are adopted one of two lanes, respectively. Compared one, AXTE can compensate for higher insertion loss without extra power consumption, improve measured...
