A Personal Perspective on Daily Occupations to Counteract Cancer Related Fatigue: A Case Study

Background: This case study aimed to identify and describe meaningful physical occupations used by a cancer survivor to increase or maintain levels of participation during active chemotherapy and subsequent cancer related fatigue. Method: A case study approach was used to develop an in-depth description and analysis based on one participant’s experience with breast cancer and associated treatments. A semi-structured interview was conducted. The data were analyzed through description of the case, categories, and themes. It also included categorical aggregation in efforts to seek a collection of instances from the data to explore any issue-relevant meanings. Results: Following data analysis, one overarching theme, return to normalcy, was identified with three subthemes: (a) prioritization of meaningful activities, (b) modifications to activities or routines, (c) lack of referral for immediate needs. Conclusion: Personal knowledge of occupational therapy practice provided support for enhancing engagement in daily meaningful occupations. Lessons learned from this experience could be applied to clients experiencing cancer related side effects to improve engagement in daily occupations

Local triple derivations on real C*-algebras and JB*-triples

We study when a local triple derivation on a real JB*-triple is a triple derivation. We find an example of a (real linear) local triple derivation on a rank-one Cartan factor of type I which is not a triple derivation. On the other hand, we find sufficient conditions on a real JB*-triple E to guarantee that every local triple derivation on E is a triple derivation

Single atom edge-like states via quantum interference

We demonstrate how quantum interference may lead to the appearance of robust edge-like states of a single ultracold atom in a two-dimensional optical ribbon. We show that these states can be engineered either within the manifold of local ground states of the sites forming the ribbon, or of states carrying one unit of angular momentum. In the former case, we show that the implementation of edge-like states can be extended to other geometries, such as tilted square lattices. In the latter case, we suggest to use the winding number associated to the angular momentum as a synthetic dimension.Comment: 5 pages, 5 figure

2-local triple homomorphisms on von Neumann algebras and JBW∗^*-triples

We prove that every (not necessarily linear nor continuous) 2-local triple homomorphism from a JBW$^*$-triple into a JB$^*$-triple is linear and a triple homomorphism. Consequently, every 2-local triple homomorphism from a von Neumann algebra (respectively, from a JBW$^*$-algebra) into a C$^*$-algebra (respectively, into a JB$^*$-algebra) is linear and a triple homomorphism

Local triple derivations on C*-algebras

We prove that every bounded local triple derivation on a unital C*-algebra is a triple derivation. A similar statement is established in the category of unital JB*-algebras.Comment: 12 pages, submitte

The Indubitable Nature of Temporality in Perception

The flow of time is vital for perception. While philosophers disagree as to the nature of how time is represented, i.e. that the passage of time is that of mere tense or belonging to the nature of the experience, it is generally accepted that the represented somehow tells us about the future, present and past. My contention is that this temporal character is indubitable for perception. I will begin by providing a temporal model of how percepts are represented. After giving a detailed presentation of the model, some problems will be considered, namely that the temporal model is doomed by the reversal of causal relata or no different than an unsuccessful perceptual experience. My contention will be that what is being represented in perception possesses fundamental temporal qualities that are indubitable for the experience, regardless of metaphysical worries or perceptual worries. If such temporal qualities belonging to the represented go without say, then a question remains as to the status of the temporal character of perception. After contrasting Kant’s position with Husserl’s position on the status of temporality in perception, I will argue that Kant’s position on perceptual temporality as manifesting from a cognitive faculty is more plausible
