Abstract: Provided is a recombinant polypeptide containing at least one immunogenic fragment of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-COV-2) spike glycoprotein, and pharmaceutical compositions containing the same.

Abstract: Provided is a recombinant polypeptide containing at least one immunogenic fragment of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) spike glycoprotein. Also provided are a method for preventing, inhibiting, reducing, eliminating, protecting, or delaying the onset of an infection or an infectious clinical condition caused by a coronavirus in a subject which includes administering to the subject the recombinant polypeptide, and a method for inducing an immune response against a coronavirus in a subject, which includes administering to the subject the recombinant polypeptide.

Abstract: An artificial neuron includes an aggregator that combines a plurality of input signals. The value state of each of the input signals is encoded in a phase thereof. The artificial neuron also includes an actuator in communication with the aggregator. The actuator is configured to provide an output signal having a value state encoded in a phase thereof. The value state of the output signal may be selected on the basis of the value states of the input signals. The value state of each of the input signals and/or the output signal may be a logical state.
