The total least squares (TLS) techniques, also called orthogonal regression and errors-in-variables modeling, see [15, 16], have been developed independently in several areas. For a given linear (orthogonally invariant) approximation problem AX ≈ B, where A ∈ Rm×n, B ∈ Rm×d, X ∈ Rn×d, the TLS formulation aims at a solution of a modified problem (A + E)X = B + G such that min ‖[G,E]‖F . The alge...

The treatment of multiple myeloma is evolving rapidly. The development of immunomodulatory drugs (IMiDs) in the late 1990s and proteasome inhibitors (PIs) in the first decade of this century has dramatically changed the outlook for patients, as we began seeing response rates never before imagined. Today the so-called novel agents are no longer novel but standard of care, and are being joined by...

Coronary artery aneurysm is a rare congenital or acquired anomaly. The commonest location of coronary artery aneurysms is the right coronary artery and they are found slightly more often in males. We report an unusual case of multiple and extremely large aneurysms, therefore potentially at risk of rupture or thrombosis.

Most calculations in lattice Quantum Chromodynamics (QCD) involve the solution of a series of linear systems of equations with exceedingly large matrices and a large number of right hand sides. Iterative methods for these problems can be sped up significantly if we deflate approximations of appropriate invariant spaces from the initial guesses. Recently we have developed eigCG, a modification o...

we report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (sln) biopsy.  four peritumoral intradermal tc-99m phytate injection was performed and slns were detected in both axillary and right inguinal regions. on the biopsy only the right axillary sln was metastatic leading to right axilla...

background: a hemangioma is a rather common benign soft tissue tumor that rarely originates from both the pectoralis muscle and the breast. vascular tumors of the breast, such as benign hemangiomas, are rarely seen in men. case presentation: a 40-year-old man presented with a non-tender palpable right breast mass since 6 months ago. on physical examination, a hard lump was detected in the centr...

We report a young male with an initial excisional biopsy report of melanoma of the lower back, referred to our hospital for complete excision and sentinel lymph node (SLN) biopsy.  Four peritumoral intradermal Tc-99m phytate injection was performed and SLNs were detected in both axillary and right inguinal regions. On the biopsy only the right axillary SLN was metastatic leading to right axilla...

Dental anomalies are rare findings that may affect development of occlusion and early intervention may be required. Here, a case of multiple anomalies in primary and perma‌nent dentitions is reported. The patient referred to the dental center with the chief complaint of multiple tooth decay. In the oral examination, the rare case of triplica‌tion between the right geminated man-dibular A and...
