Solitary fibrous tumour is an uncommon mesenchymal neoplasm previously thought to only originate from the pleura; it is seen only rarely in an extra-pleural location. We report the first case of pancreatic solitary fibrous tumour in an 87-year-old woman that has metastasized to the lungs and subcutaneous tissue. We have identified a solitary mass excised from the groin region, which is positive...

Plasmacytoma is a plasma cell neoplasm that locally infiltrates a bone or spreads to extramedullary areas. A new World Health Organization criterion defines solitary plasmacytoma of bone as a localized bone tumor consisting of plasma cells identical to those seen in plasma cell myeloma, which is manifested as a solitary osteolytic lesion in a radiological evaluation. Primary tumors of the stern...

The rarefactive KdV solitary waves in a dusty plasma have been extensively studied analytically and found experimentally in the previous works. Though the envelope solitary wave described by a nonlinear Schrödinger equation (NLSE) has been proposed by using the reductive perturbation method, it is first verified by using the particle-in-cell (PIC) numerical method in this paper. Surprisingly, t...

The excitation and propagation of finite-amplitude low-frequency solitary waves are investigated in an argon plasma impregnated with kaolin dust particles. A nonlinear longitudinal dust acoustic solitary wave is excited by pulse modulating the discharge voltage with a negative potential. It is found that the velocity of the solitary wave increases and the width decreases with the increase of th...

The objective of this paper is to study the existence of solitary wave solutions of a fifth order model equation for steady capillary-gravity waves over a bump with the Bond number near 1/3. We proved that there exist solitary wave solutions of the model equation for a sufficiently smooth compact bump. Key-Words: Steady capillary-gravity wave, Solitary wave solution, Compact bump.

Solitary metastasis of uveal melanoma to bone is extremely rare and usually associated with other organ involvement. We present a rare case of an ocular melanoma patient presenting with solitary metastasis to the clavicle two years after enucleation, without any other organ involvement. In this report, we tried to present our treatment strategy for the solitary metastasis of bone.

Solitary fibrous tumor is an uncommon mesenchymal neoplasm. Liver is a rare location of this tumor. We report a case of hepatic solitary fibrous tumor in a 56-year-old female, who presented with right upper abdominal pain. An extended right hepatectomy was performed. Histopathological and immunohistochemical examination revealed solitary fibrous tumor of the liver.

Neurofibromas are benign peripheral nerve sheath tumours, which are usually solitary and sporadic. Solitary neurofibromas of the breast are rare. The most common location of a breast neurofibroma is the nipple-areola complex. We report a rare case of a 56-year-old woman with a solitary neurofibroma of the right breast sulcus.

We study the behavior of solitary-wave solutions of some generalized nonlinear Schrödinger equations with an external potential. The equations have the feature that in the absence of the external potential, they have solutions describing inertial motions of stable solitary waves. We construct solutions of the equations with a non-vanishing external potential corresponding to initial conditions ...

In this paper, we propose a health and environment monitoring service for solitary seniors using semantic web technologies (ontology modeling, semantic annotation, and ontology-based context awareness). This service defines and logically deducts the environmental conditions which threaten the health of the solitary seniors. This service includes solitary senior, guardian, social workers, health...
