A case of left distal forearm and wrist osteolipoma in a 56 year old female is reported. The patient presented with a 3 year history of nontender left wrist mass. Radiographs demonstrated a lobulated mass of mixed low density and calcifications, not adjacent to and with no connection to underlying bone.

Here, we present strong numerical evidence that stable knots and links such as trefoils and Hopf links do exist in simple, complex, and chaotic oscillatory systems if the coupling between the oscillators is neither too short ranged nor too long ranged. In this case, effective repulsive forces between vortex lines in knotted and linked structures stabilize curvature-driven shrinkage observed for single vortex rings.

However, its role in hepatocellular carcinoma (HCC) has not yet been illustrated. The present study aimed to investigate the expression and epigenetic regulation of PLZF as well as its clinical significance in HCC.

Recent studies have analyzed the bacterial composition in the respiratory tract of chronic obstructive pulmonary disease (COPD), influenza and tuberculosis patients, and have identified novel targets that may potentially lead to secondary infections. Certain bacteria have also been found to regulate the lung immune system and have unexpected connections with respiratory diseases.

We present numerical results for various information theoretic properties of the square lattice Ising model. First, using a bond propagation algorithm, we find the difference 2H(L)(w)-H(2L)(w) between entropies on cylinders of finite lengths L and 2L with open end cap boundaries, in the limit L→∞. This essentially quantifies how the finite length correction for the entropy scales with the cylinder circumference w.

Ordinary bond percolation (OP) can be viewed as a process where clusters grow by joining them pairwise, adding links chosen randomly one by one from a set of predefined virtual links. In contrast, in agglomerative percolation (AP) clusters grow by choosing randomly a target cluster and joining it with all its neighbors, as defined by the same set of virtual links. Previous studies showed that AP is in different universality classes from OP for several types of (virtual) networks (linear chains, trees, Erdös-Rényi networks), but most surprising were the results for two-dimensional (2D) lattices: While AP on the triangular lattice was found to be in the OP universality class, it behaved completely differently on the square lattice.
