Advanced welding automation: Intelligent systems for multipass welding in Butt Double V-Groove and Tee Double Bevel configurations.

The paper addresses the imperative shift towards automation in welding processes, leveraging advanced technologies such as industrial robotic systems. Focusing on the reconstruction and classification of weld joints, it introduces a methodology for automatic trajectory determination. Utilizing a laser profilometer mounted on the robot, weld joints are reconstructed in three dimensions, and spurious data is filtered out through signal processing.

Nonreciprocity in CHIKV and MAYV Vaccine-Elicited Protection.

Chikungunya virus (CHIKV) is a pathogenic arthritogenic alphavirus responsible for large-scale human epidemics for which a vaccine was recently approved for use. Mayaro virus (MAYV) is a related emerging alphavirus with epidemic potential with circulation overlap potential with CHIKV. We previously reported the ability of a non-replicating human adenovirus (AdV)-vectored vaccine expressing the MAYV structural polyprotein to protect against disease in mice following challenge with MAYV, CHIKV and UNAV.

"Prepectoral tissue expanders without mesh as a bridge to delayed autologous breast reconstruction: Experience at a single academic center".

Acellular dermal matrix (ADM) is a useful adjunct in implant-based breast reconstruction. The benefits of using ADM with an expander as a temporary bridge to delayed autologous reconstruction are unknown. Placing prepectoral tissue expanders, without ADM, as a bridge to delayed autologous reconstruction could yield cost savings, shorten operating time and decrease complications.

Mucosal adenovirus vaccine boosting elicits IgA and durably prevents XBB.1.16 infection in nonhuman primates.

A mucosal route of vaccination could prevent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) replication at the site of infection and limit transmission. We compared protection against heterologous XBB.1.
