Measurement of Λ_{b}^{0}, Λ_{c}^{+}, and Λ Decay Parameters Using Λ_{b}^{0}→Λ_{c}^{+}h^{-} Decays.

A comprehensive study of the angular distributions in the bottom-baryon decays Λ_{b}^{0}→Λ_{c}^{+}h^{-}(h=π,K), followed by Λ_{c}^{+}→Λh^{+} with Λ→pπ^{-} or Λ_{c}^{+}→pK_{S}^{0} decays, is performed using a data sample of proton-proton collisions corresponding to an integrated luminosity of 9  fb^{-1} collected by the LHCb experiment at center-of-mass energies of 7, 8, and 13 TeV. The decay parameters and the associated charge-parity (CP) asymmetries are measured, with no significant CP violation observed. For the first time, the Λ_{b}^{0}→Λ_{c}^{+}h^{-} decay parameters are measured.

Harmless and efficient nickel enrichment from nickel-containing waste slag using vitrification technology.

With the growing demand for nickel in the stainless steel and battery industries, conventional methods of extracting nickel from ores face challenges such as high production costs and environmental concerns. This study proposes a new process for the recovery of nickel metal and the production of nickel-iron alloys from nickel-bearing scrap. The reduction rates of nickel and iron oxides were investigated by optimizing the roasting temperature, time, and C/O ratio, and the process was optimized using response surface methodology (RSM).

Comparative transcriptome analysis reveals the key role of photosynthetic traits in the formation of differences in photothermal sensitivity in tobacco.

Background: The photothermal sensitivity of tobacco refers to how tobacco plants respond to variations in the photothermal conditions of their growth environment. The degree of this sensitivity is crucial for determining the optimal planting regions for specific varieties, as well as for improving the quality and yield of tobacco leaves. However, the precise mechanisms underlying the development of photothermal sensitivity in tobacco remain unclear.

Lift-CM: An integrated lift-heater centrifugal microfluidic platform for point-of-care pathogen nucleic acid detection using isothermal amplification and CRISPR/Cas12a.

Pathogen nucleic acid detection technology based on isothermal amplification and CRISPR/Cas12a system offers advantages in terms of high sensitivity, high specificity, and rapidity. However, this method has not been widely applied because of its shortcomings in utilizing conventional instruments, which cannot satisfy the requirements for Point of Care Testing (POCT), such as integration, convenience, and miniaturization. In this study, we developed an integrated lift-heater centrifugal microfluidic platform (Lift-CM) to automate the processes of isothermal amplification and CRISPR/Cas12a detection.
