[Interpretation of key points from the "Expert Consensus on Diagnosis and Management of Neonatal Cow Milk Protein Allergy (2023)"].

The clinical manifestations of cow's milk protein allergy (CMPA) in neonates are non-specific and involve multiple organ systems. CMPA may also adversely affect physical growth and central nervous system development in neonates, lead to functional disorders, and increase anxiety and stress among family members. Due to the lack of specific clinical manifestations and diagnostic methods, the diagnosis and management of CMPA in neonates continue to pose significant clinical challenges.

Large-scale sub-5-nm vertical transistors by van der Waals integration.

Vertical field effect transistor (VFET), in which the semiconductor is sandwiched between source/drain electrodes and the channel length is simply determined by the semiconductor thickness, has demonstrated promising potential for short channel devices. However, despite extensive efforts over the past decade, scalable methods to fabricate ultra-short channel VFETs remain challenging. Here, we demonstrate a layer-by-layer transfer process of large-scale indium gallium zinc oxide (IGZO) semiconductor arrays and metal electrodes, and realize large-scale VFETs with ultra-short channel length and high device performance.

High-density vertical sidewall MoS transistors through T-shape vertical lamination.

Vertical transistors, in which the source and drain are aligned vertically and the current flow is normal to the wafer surface, have attracted considerable attention recently. However, the realization of high-density vertical transistors is challenging, and could be largely attributed to the incompatibility between vertical structures and conventional lateral fabrication processes. Here we report a T-shape lamination approach for realizing high-density vertical sidewall transistors, where lateral transistors could be pre-fabricated on planar substrates first and then laminated onto vertical substrates using T-shape stamps, hence overcoming the incompatibility between planar processes and vertical structures.
