SUMMARY Sorghum is an important crop for food, forage, wine and biofuel production. To enhance its transformation efficiency without negative developmental by‐effects, we investigated the impact of GRF4‐GIF1 chimaera GRF5 on sorghum transformation. Both effectively improved accelerated process to less than 2 months which was not observed when using BBM‐WUS. As agrobacterium effectors increase ability T‐DNA transfer into plant cells, checked whether ternary vector system can additively The...
A facile ECL immunosensor for the sensitive detection of prostate-specific antigen was constructed based on a co-reactant modulating strategy using Cu 2+ -modified NH 2 -metal–organic framework nanoprobes as units.
In magnetotelluric (MT) simulations, the enforcement of Dirichlet boundary condition (BC) necessitates padding a region extension (ROE) to core interest (ROI) in model. The ROE typically has size several skin depths and hence computational domain can easily be hundreds kilometers for broadband MT surveys. A large number cells are therefore required discretize ROE, wasting computing resources solving electric field ROE. To address this issue, we developed 3D nested finite element algorithm...
Abstract Ultralow frequency (ULF) waves have long been known to resonate with magnetospheric charged particles through their drift and bounce motions. Most research interest has focused on the resonance motion, which can accelerate at very high energies. The role of especially for lower energies, attracted less attention so far. Here we start from general theory wave‐particle interactions predict characteristic, observable signatures drift‐bounce resonance. Such be described in particle...
Abstract Short large‐amplitude magnetic structures (SLAMS) frequently appear near the bow shock. Inside steepening SLAMS, whistler‐mode waves are coherently generated at their leading edges. These crucial for electron dynamics, energy conversion and reconnection Nevertheless, characteristics generation of inside SLAMS still unclear. In this study, we conducted a statistical analysis within Earth's shock to investigate properties mechanisms. We found that these mainly excited by temperature...
Abstract Organic photodetectors (OPDs) have attracted immense interest as solution‐processable optical signal‐capturing devices due to their various advantages, such adjustable response range, excellent weak light response, lightweight, flexibility, and ease of processing on diverse substrates. Low dark current density ( J d ) high responsivity R are key requirements necessary for achieving a specific detectivity D *). Here, an effective strategy preparing high‐performance OPDs with...
Monitoring the succession of bacterial populations during corn stover ensiling is helpful for improving silage quality.Fermentation characteristics were assessed and communities described along with process. The ensiled exhibited chemical traits, such as low pH value (3·92 ± 0·02) high levels lactic acid (66·75 1·97 g kg-1 dry matter (DM)), which associated well-ensiled forages, well moderate concentrations acetic (19·69 1·51 DM) small amounts 1,2-propanediol (4·4 0·11 DM). In early stages...
A highly efficient extracavity Raman laser pumped by the infrared nanosecond pulses is presented utilizing recently recommended medium-strontium tungstate crystal (SrWO/sub 4/).

Abstract The role of whistler-mode waves in the solar wind and relationship between their electromagnetic fields charged particles is a fundamental question space physics. Using high-temporal-resolution field plasma data from Magnetospheric MultiScale spacecraft, we report observations low-frequency whistler associated particle behavior Earth’s foreshock. frequency these close to half lower-hybrid (∼2 Hz), with wavelength ion gyroradius. electron bulk flows are strongly modulated by waves,...
Abstract Using the high‐time‐resolution data from Magnetospheric Multiscale mission, precursor waves upstream of foreshock transient (FT) shocks are statistically investigated using four‐spacecraft timing method.

Combining with feature right‐hand polarization PRF, precursors identified as whistler‐mode around lower hybrid frequency. occurrence is independent...

Abstract A localized Pc4‐5 ultralow‐frequency (ULF) wave event associated with a plasmaspheric plume was observed by THEMIS‐E on the dawnside near L = 6, which identified as second harmonic poloidal wave. The sudden density enhancement during an outbound pass. charged particle populations in have variety of periodic modulation characteristics at different energies. First, there is antiphase relationship between magnetic field Br and flux across wide energy range both for ions electrons (~50...
In the present research, microstructural alteration and microhardness at near-surface of AISI H13 steel by hard milling under different cutting parameters with coated tools have been investigated. Very thin white layer forms or even no obvious appears near-surface. It is reasonable that formation very primarily due to mechanical effect (severe plastic deformation) rather than thermal (rapid heating quenching). The ‘hook’ shape profile indicates highest on top surface; while smallest occurs...
