Peter Bergmann on observables in Hamiltonian General Relativity: A historical-critical investigation.

Publication Type:Academic Journal

Source(s):Studies in history and philosophy of science [Stud Hist Philos Sci] 2022 Oct; Vol. 95, pp. 1-27. Date of Electronic Publication: 2022 Aug 02.

Abstract:The problem of observables and their supposed lack of change has been significant in Hamiltonian quantum gravity since the 1950s. This paper considers the unrecognized variety of ideas about observables in the thought of constrained Hamiltonian dynamic...

Force and electromyography reflections of sensory action-effect weighting during pinching.

Publication Type:Academic Journal

Source(s):Human movement science [Hum Mov Sci] 2022 Aug; Vol. 84, pp. 102969. Date of Electronic Publication: 2022 Jun 12.

Abstract:Ideomotor theories suggest that different action-effects are not equally important in goal-directed actions, and that task-relevant information are weighted stronger during the representation of actions. This stronger weighting of task-relevant action-...

Defense against Adversarial Swarms with Parameter Uncertainty.

Publication Type:Academic Journal

Source(s):Sensors (Basel, Switzerland) [Sensors (Basel)] 2022 Jun 24; Vol. 22 (13). Date of Electronic Publication: 2022 Jun 24.

Abstract:This paper addresses the problem of optimal defense of a high-value unit (HVU) against a large-scale swarm attack. We discuss multiple models for intra-swarm cooperation strategies and provide a framework for combining these cooperative models with HVU...
