Serological assays capable of measuring antibody responses induced by previous infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been critical tools in the response to the COVID-19 pandemic.In this study, we use bead-based multiplex assays to measure IgG and IgA antibodies and IgG avidity to five SARS-CoV-2 antigens (
Danger is a fundamental aspect of the lives of most animals.Adaptive behavior therefore requires avoiding actions, objects, and environments associated with danger.Previous research has shown that humans and non-human animals can avoid such dangers through two types of behavioral adaptions, (i) genetic preparedness to avoid certain stimuli or actio
The paper considers the class of Hamiltonian systems with two degrees of freedom.Based on the classical normal form, according to the rules of Born-Jordan and Weyl-MacCoy, its quantum analogs are constructed for which the eigenvalue problem is solved and approximate formulas for the energy spectrum are sd11i found.For particular values of the param
Abstract Background The risk of injury is one of the major barriers to engaging in cycling.We investigated exposure-based rates and profiles of traffic injuries sustained by pedal cyclists that resulted in death or hospital inpatient treatment in New Zealand, one of the most car dependent countries.Methods Pedal cyclist traffic injuries were identi
The article deals with the problems of transformation of St.Petersburg industrial territories including the impressive number of monuments of industrial architecture.The work objective: to trace the application of various methods of transformation - reconstruction, restoration and new construction - by way of examples of St.Petersburg historic indu
