D-brane Solitons in Supersymmetric Sigma-Models [PDF]
, 2000 Massive D=4 N=2 supersymmetric sigma models typically admit domain wall (Q-kink) solutions and string (Q-lump) solutions, both preserving 1/2 supersymmetry. We exhibit a new static 1/4 supersymmetric `kink-lump' solution in which a string ends on a wall,

A Case of Juvenile Giant Fibroadenoma of Breast: A Diagnostic Dilemma
International Journal of Anatomy Radiology and Surgery, 2023 Fibroadenomas are the most common type of breast tumours diagnosed in young women. Fibroadenomas found in children and adolescents are termed as juvenile fibroadenomas of which giant fibroadenomas are rare account for 0.5%-2% of all fibroadenomas, that ...

Invasive Cystic Hypersecretory Carcinoma of Breast: A Rare and Under Diagnosed Variant of Ductal Carcinoma [PDF]
Journal of Clinical and Diagnostic Research, 2017 Handful cases of invasive Cystic Hypersecretory Ductal Carcinoma (CHC) have been reported so far in literature. Cystic hypersecretory lesions of breast have a spectrum of morphological features ranging from Cystic Hypersecretory Hyperplasia (CHH), CHH ...

Moduli Spaces of Lumps on Real Projective Space [PDF]
, 2015 Harmonic maps that minimize the Dirichlet energy in their homotopy classes are known as lumps. Lump solutions on real projective space are explicitly given by rational maps subject to a certain symmetry requirement.

Field theory models for tachyon and gauge field string dynamics [PDF]
, 2000 In hep-th/0008227, the unstable lump solution of \phi^3 theory was shown to have a spectrum governed by the solvable Schroedinger equation with the \ell=3 reflectionless potential and was used as a model for tachyon condensation in string theory. In this

Development of a Transient Model of a Stirling-Based CHP System
Energies, 2013 Although the Stirling engine was invented in 1816, this heat engine still continues to be investigated due to the variety of energy sources that can be used to power it (e.g., solar energy, fossil fuels, biomass, and geothermal energy).

Abundant lump-type solutions for the extended (3+1)-dimensional Jimbo–Miwa equation
Results in Physics, 2021 In this work, we research the mixed lump–kink solutions and their dynamic properties of the extended (3+1)-dimensional Jimbo–Miwa equation. Mixed lump–kink solutions are triggered by the interaction between lump soliton and exponential function, the ...
