Eyelid bags
Eyelid bags are considered a sign of ageing, but they often appear prematurely due to the variety of causes that favor them. This brief report describes the case of a patient who was referred to us for the correction of a second degree bilateral palpebral ptosis that the patient had suffered from for several years and that in recent months had worsened to the point of interfering with vision an...
متن کاملMagnetic bags in hyperbolic space
A magnetic bag is an abelian approximation to a large number of coincident SU(2) BPS monopoles. In this paper we consider magnetic bags in hyperbolic space and derive their Nahm transform from the large charge limit of the discrete Nahm equation for hyperbolic monopoles. An advantage of studying magnetic bags in hyperbolic space, rather than Euclidean space, is that a range of exact charge N hy...
متن کاملVisualizing Bags of Vectors
The motivation of this paper is two-fold a) to compare between two different modes of visualizing data that exists in a bag of vectors format b) to propose a theoretical model that supports a new mode of visualizing data. Visualizing high dimensional data can be achieved using Minimum Volume Embedding, but the data has to exist in a format suitable for computing similarities while preserving lo...
متن کاملOn Ordering of Bags
The following propositions are true: (1) For all sets x, y, z such that z ∈ x and z ∈ y holds x \ {z} = y \ {z} iff x = y. (2) For all natural numbers n, k holds k ∈ Seg n iff k−1 is a natural number and k − 1 < n. Let f be a natural-yielding function and let X be a set. One can verify that f↾X is natural-yielding. Let f be a finite-support function and let X be a set. One can check that f↾X is...
متن کاملLiposomes: bags of challenge.
The major problem in chemotherapy is the targetting of drugs to restricted anatomical sites and specific target cells. Many drugs produce side effects, are toxic to normal tissues and are often prematurely inactivated or excreted. To overcome such difficulties, several forms of drug carriers have been described and tested in animals, and on some occasions in man (Ryman & Tyrrell, 1980; Gregoria...
