Statues and Lumps: A Strange Coincidence?
This paper attacks various arguments for the impossibility of coinciding objects. Distinguishing a temporally relative from an absolute sense of ‘the same’, we see that the intuition, ‘this is only one thing’, and the dictum, ‘two things cannot occupy the same place at the same time’, are individuating things at a time rather than absolutely and are therefore compatible with coincidence.

متن کاملCoexistence of a pituitary macroadenoma and multicentric paraganglioma: a strange coincidence.
A 50-year-old woman was referred to our hospital for evaluation of a mass on the right side of the neck. She had a past medical history of multiple interventions of cosmetic surgery in her face and breasts. She also had a macroprolactinoma treated with transsphenoidal surgery in our clinic in 1993 because of intolerance to bromocriptine. The surgery confirmed the diagnosis of lactotroph adenoma...
متن کاملHow strange a non-strange heavy baryon?
We give some general arguments in favor of the large magnitude of matrix elements of an operator associated with nonvalence quarks in heavy hadrons. We estimate matrix element 1 2mΛb 〈Λb|s̄s|Λb〉 ≃ 1 ÷ 2 for Λb baryon whose valence content is b, u, d quarks. This magnitude corresponds to a noticeable contribution of the strange quark into the heavy baryon mass 1 2mΛb 〈Λb|mss̄s|Λb〉 ≃ 200 ÷ 300MeV ....
متن کاملOncogenic osteomalacia: strange tumours in strange places.
Two patients presented with hypophosphataemic osteomalacia and were subsequently found to have small tumours unusual histopathology and location causing the osteomalacia. Each tumour was found after an intensive search for occult masses. Studies of vitamin D metabolism and renal tubular function before and after surgery yielded further insight into the pathophysiology of oncogenic osteomalacia....
متن کاملStrange Carers
The present comment focuses on the distinction between attachment as bond formation and expectations of availability and responsiveness (security) within attachment relationships. We enumerate key components of bonding and functions of carer secure base support. Our analysis has implications for design and suggests that robots are unlikely to serve effectively as sole carers. Even with robots a...
