Blow-up of the viscous heat-conducting compressible flow

We show the blow-up of smooth solution of viscous heat-conducting flow when the initial density is compactly supported. This is an extension of Z. Xin's result\cite{xin} to the case of positive heat conduction coefficient but we do not need any information for the lower bound of the entropy. We control the lower bound of second moment by total energy

Disentangling bulk polymers from adsorbed polymers using the quartz crystal microbalance

At sufficient adhesion energy, polymers may adsorb irreversibly at an interface, with many adhesion sites per polymer and significant changes in their conformation. In addition to irreversibly adsorbed polymers there may be reversibly adsorbed polymers, which are in dynamic equilibrium with bulk polymers, and which have fewer adhesion sites per polymer and less significant conformational changes. In this work, we simultaneously determine the viscoelasticity of irreversibly adsorbed polymers, reversibly adsorbed polymers, and bulk polymers. To this end, we combine hydrodynamic modelling with quartz crystal microbalance-dissipation (QCM-D) measurements involving an adsorbing target surface and a non-adsorbing, i.e., passivated surface. We apply the method to polyethylene glycol adsorption at the water–silica interface. The results demonstrate that the viscoelasticity of the reversibly adsorbed polymers is similar to that of the bulk polymers, whereas the irreversibly adsorbed polymers are less elastic. This is the first approach to decouple these viscoelastic contributions, which provides a new analytical tool to quantify the kinetics and conformation of reversibly adsorbed polymers, shedding light on polymer dynamics near interfaces

Joint Blind Motion Deblurring and Depth Estimation of Light Field

Removing camera motion blur from a single light field is a challenging task since it is highly ill-posed inverse problem. The problem becomes even worse when blur kernel varies spatially due to scene depth variation and high-order camera motion. In this paper, we propose a novel algorithm to estimate all blur model variables jointly, including latent sub-aperture image, camera motion, and scene depth from the blurred 4D light field. Exploiting multi-view nature of a light field relieves the inverse property of the optimization by utilizing strong depth cues and multi-view blur observation. The proposed joint estimation achieves high quality light field deblurring and depth estimation simultaneously under arbitrary 6-DOF camera motion and unconstrained scene depth. Intensive experiment on real and synthetic blurred light field confirms that the proposed algorithm outperforms the state-of-the-art light field deblurring and depth estimation methods

Chondrosarcoma: With Updates on Molecular Genetics

Chondrosarcoma (CHS) is a malignant cartilage-forming tumor and usually occurs within the medullary canal of long bones and pelvic bones. Based on the morphologic feature alone, a correct diangosis of CHS may be difficult, Therefore, correlation of radiological and clinicopathological features is mandatory in the diagnosis of CHS. The prognosis of CHS is closely related to histologic grading, however, histologic grading may be subjective with high inter-observer variability. In this paper, we present histologic grading system and clinicopathological and radiological findings of conventional CHS. Subtypes of CHSs, such as dedifferentiated, mesenchymal, and clear cell CHSs are also presented. In addition, we introduce updated cytogenetic and molecular genetic findings to expand our understanding of CHS biology. New markers of cell differentiation, proliferation, and cell signaling might offer important therapeutic and prognostic information in near future

Otologic Manifestation in IgG4-Related Systemic Disease

IgG4-related systemic disease, including autoimmune pancreatitis, is a multi-organ disorder characterized by elevated serum immunoglobulin G4 (IgG4) concentration and IgG4-positive plasma cell infiltration. We report a case of a 66-year-old woman with IgG4-related hearing disorder, presenting with fluctuating mixed hearing loss with middle ear effusion. The serum IgG4 level was elevated and pathological examination revealed dense infiltration of IgG4-positive lymphocyte in the renal parenchyma, lung tissue and lacrimal gland. With intravenous methylprednisolone at a dose of 60 mg daily, improvement of hearing loss were observed. No recurrence was observed for 6 months with mainternance of prednisolone and methotrexate
