cytes. Immunostaining with melan-A antibody confirmed a moderate augmentation in the number of basal melanocytes with branching dendrites extending into the suprabasal layers of the epidermis, sometimes resembling the spreading branches of a tree ( fig. 1 e). Case 2. A 60-year-old man presented with a long-standing history of a pigmented macule of the lower lip. Clinical examination showed a br...

This paper focuses on the provision of QoS in a Multi-hop Wireless Network (MHWN) environment. The approach proposed here is based on the introduction of the Wireless Adaptation Layer (WAL), an intermediate layer between the IP layer and the DLC/PHY layers at each communication node within the MHWN. The scope of the WAL is to cope with the wireless channel impairments and provide improved QoS s...

The coupled interaction of long standing hydrodynamic waves with a deformable non-Newtonian seabed is examined using a two-layer model for which the upper layer fluid is inviscid and the lower layer is bi-viscous. The two-dimensional response of the system to forcing by a predominantly longitudinal (cross-shore) standing wave perturbed by a small transverse (along-shore) component is determined...

We report thickness-dependent morphologies of a Pd film on n-layer graphenes. Via Raman spectroscopy-based technique, obvious charge transfer has been observed among Pd and graphenes, which is also dependent on the layer number. With the increase of the layer number, the Pd film becomes coarser, and the electron transfer becomes lower.

We show that the magnetic kink waves generated by the motions of the photospheric footpoints of the coronal ux tubes can supply adequate energy for heating the quiet corona. We model the solar corona as two-layer isothermal atmosphere, with the lower layer having chromospheric thickness and the temperature and the upper layer having coronal temperature.

We generalize the methods of two-dimensional contour dynamics to study a twolayer rotating fluid that obeys the quasi-geostrophic equations. We consider here only the case of a constant-potential-vorticity lower layer. We derive equilibrium solutions for monopolar (rotating) and dipolar (translating) geostrophic vortices in the upper layer, and compare them with the Euler case. We show that the...

Interneuronal networks in neocortex underlie feedforward and feedback inhibition and control the temporal organization of pyramidal cell activity. We previously found that lower layer neocortical interneurones can reach action potential threshold in response to the stimulation of a single presynaptic cell. To better understand this phenomenon and the circuit roles of lower layer neocortical int...
