Understanding a Strange Phenomenon: Lilliputian Hallucinations
Lilliputian hallucinations are infrequent but reported in a variety of states ranging from toxic metabolic states, medical, neurological and psychiatric conditions. We report three cases with different psychiatric diagnoses all presenting with vivid Lilliputian hallucinations. An attempt to apply the current biological mechanisms that explain complex visual hallucinations to Lilliputian halluci...
متن کاملA Strange Phenomenon for the Singular Values of Commutators with Rank One Matrices∗
The singular values of XY − Y X are the objects under investigation. Here, X and Y are square matrices with complex entries, and one of them has rank one. Hence, there are at most two non-trivial numbers among the commutator’s singular values, and the pairs of interest can be depicted in the plane. The emphasis will lie on the unexpectedly intriguing case in which both matrices are of rank one ...
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 کاملIn a Strange Land
Ignorance of the culture and traditions of immigrants leads to misunderstanding and is a factor in mental illness among people whose new home seems intimidating as Dr. Farrukh Hashmi, a psychiatrist and a member of the Midlands Race Relations Board, explains. an immigrant was taken to a mental hospital because he was said to have been aggressive, had been shouting at his family, and he had thre...
متن کاملA strange gait.
A 5-year-old afebrile girl presented to the office with an antalgic limp and left foot pain that lasted 3 weeks. On physical examination, swelling and redness were present and the top of the midfoot was painful to touch. Weight-bearing radiographs of the 2 feet were obtained (Figures 1-3; Figures 1 and 2 available at www.jpeds.com). The left foot navicular bone appears “wafer like”—flattened wi...
