The concept of pure optical photoacoustic microscopy(POPAM) was proposed based on optical rastering of a focused excitation beam and optically sensing the photoacoustic signal using a microring resonator fabricated by a nanoimprinting technique. After the refinements of the microring's working wavelength and in the resonator structure and mold fabrication, an ultrahigh Q factor of 3.0×10(5) was...

The pure-injective R-modules are defined easily enough: as those modules which are injective over all pure embeddings, where an embedding A → B is said to be pure if every finite system of R-linear equations with constants from A and a solution in B has a solution in A. But the definition itself gives no indication of the rich theory around purity and pure-injectivity. The purpose of this surve...

The correspondence between the integrability of classical mechanical systems and their quantum counterparts is not a 1-1, although some close correspondencies exist. If a classical mechanical system is integrable with invariants that are polynomial in momenta one can construct a corresponding commuting set of differential operators. Here we discuss some 2or 3-dimensional purely quantum integrab...

Mucinous carcinoma of the breast is a well differentiated, rare histological type of invasive ductal carcinoma, seen in oldest median age (69 years). We describe a case of a 60 yr old female with large right breast mass of 10 years duration with no nodal involvement. The reasons to present this case are 1) Because of its rarity. 2) Despite having a large tumour size, the axillary lymph node ...

Leprosy is a chronic infectious disease endemic in Iran that mainly involves skin and peripheral nerves. Leprosy has several clinical forms. One of them is “Pure neural leprosy”. The diagnosis of this form is delayed due to lack of clinical signs in other tissues and can lead to permanent deformity. I will discuss my experience for 20 years in the diagnosis and treatment of this form of leprosy...
