Article Synopsis
  • Existing tensioning cable prestress is crucial for ensuring the safety of bridges, and the study introduces a micro-hole release technique for measuring the effective prestress in prestressed concrete bridges.
  • The research involved creating a strand drilling model using Solidworks and Abaqus, analyzing variables like drilling depth, diameter, and deflection angle on strand stress relief.
  • Results reveal that as hole diameter and depth increase, stress relief varies; specifically, larger holes lead to decreased alleviation, while increased deflection angles raise the error rate in stress release measurements.

Simultaneously optimizing elementary steps, such as water dissociation, hydroxyl transferring, and hydrogen combination, is crucial yet challenging for achieving efficient hydrogen evolution reaction (HER) in alkaline media. Herein, Ru single atom-doped WO nanoparticles with atomically dispersed Ru-W pair sites (Ru-W/WO -800) are developed using a crystalline lattice-confined strategy, aiming to gain efficient alkaline HER. It is found that Ru-W/WO -800 exhibits remarkable HER activity, characterized by a low overpotential (11 mV at 10 mA cm ), notable mass activity (5863 mA mg Ru at 50 mV), and robust stability (500 h at 250 mA cm ).

Further improvements to the yield potential of Chinese milk vetch seed are essential for the planting demand of green manure. Flower and pod development directly determines the number of seeds and the seed yield of Chinese milk vetch. However, the accumulation and translocation of dry matter and nitrogen between plant organs directly affects flower and pod development and morphological formation.

Article Synopsis
  • Single-atom catalysts (SACs) with adjustable structures can enhance the selectivity of the oxygen reduction reaction (ORR), although managing this process effectively remains a challenge.
  • Researchers developed niobium (Nb) SACs with specific oxygen configurations, achieving remarkable performance for the 2e ORR, showing an onset overpotential of just 9 mV and over 95% selectivity for hydrogen peroxide synthesis in a KOH solution.
  • Theoretical calculations reveal that the unique Nb-N and nearby oxygen structures improve the strength of crucial bonding interactions, which facilitates the 2e ORR pathway, paving the way for better-performing SACs.

Motivation: Protein structure can be severely disrupted by frameshift and non-sense mutations at specific positions in the protein sequence. Frameshift and non-sense mutation cases can also be found in healthy individuals. A method to distinguish neutral and potentially disease-associated frameshift and non-sense mutations is of practical and fundamental importance.

Clarifying the pattern of nitrogen absorption and utilization of rice under the treatments of combined with chemical fertilizer application and the pattern of absorption, utilization, distribution and residue of nitrogen in rice-soil system could provide basis to rational fertilization for rice planting area in southern Henan. In this study, undisturbed soil column simulation and isotope tracer technology of N were used to examine the differences of nitrogen uptake and utilization of rice, nitrogen nutrient balance of rice-soil system and nitrogen uptake, utilization, distribution and residue of nitrogen after mineralization and decomposition among seven treatments. The treatments involved 1) no fertilization (CK); 2) chemical fertilizer+22500 kg·hm (FM1); 3) chemical fertilizer+30000 kg·hm (FM2); 4) chemical fertilizer+37500 kg·hm (FM3); 5) chemical fertilizer+22500 kg·hm +lime (FM1+CaO); 6) chemical fertilizer+30000 kg·hm lime (FM2+CaO); 7) chemical fertilizer+37500 kg·hm +lime (FM3+CaO).

The control of the coordinated expression of genes is primarily regulated by the interactions between transcription factors (TFs) and their DNA binding sites, which are an integral part of transcriptional regulatory networks. There are many computational tools focused on determining TF binding or unbinding to a DNA sequence. However, other tools focused on further determining the relative preference of such binding are needed.
