1. FD MAC Protocol Design for Co-Existing WLANs in 5G Cellular Networks
Abstract In this paper, we design full-duplex (FD) medium access control (MAC) protocol for co-existing wireless local area networks (WLANs) in 5G cellular networks (WCFD-MAC). Our design considers some significant features of 5G networks, exceptionally, beamforming and FD capabilities at both, the base station and user equipment. FD communications may gener

2. Intrafollicular barriers and cellular interactions during ovarian follicle development
Abstract Follicles are composed of different interdependent cell types including oocytes, cumulus, granulosa, and theca cells. Follicular cells and oocytes exchange signaling molecules from the beginning of the development of the primordial follicles until the moment of ovulation. The follicular structure transforms during folliculogenesis; barriers form bet

3. On the design of nano-arm fractal antenna for UWB wireless applications
This paper presents the design of a nano-arm fractal antenna suitable for ultra wide band applications. The CPW-feed and fractal concept have been used to achieve the ultra wide bandwidth. The shape of the fractal geometry, the number of iterations and the number of nano-arms are the deciding factors for achieving wider impedance bandwidth. The experimental

6. Characterization of Lypopolyssacharide (LPS) effect on rat pinealocytes / Caracterização dos efeitos de LPS em pinealócitos de rato em cultura
Accumulating evidences put the pineal gland and the immune system reciprocally linked by bidirectional communication. Rat pineal gland constitutively activated NFkB, which plays a role on melatonin synthesis, is a preferential transduction pathway for cytokines and glucocorticoids (Ferreira et al., 2005; Fernandes et al., 2006). TNFα transiently inhibit

9. Gap junction modulation by extracellular signaling molecules: the thymus model
Gap junctions are intercellular channels which connect adjacent cells and allow direct exchange of molecules of low molecular weight between them. Such a communication has been described as fundamental in many systems due to its importance in coordination, proliferation and differentiation. Recently, it has been shown that gap junctional intercellular commun

10. Projeto e implementação em VLSI de uma rede neural auto-organizavel usando sintese automatica de auto nivel
: A Kohonen-based (SOFM - Self-Organizing Feature Map ) artificial neural network was simulated, modelated and hardware implemented in a VLSI circuit. A Top-Down methodological approach was used by using ANSI-C and VHDL (Very High Speed Circuits, Hardware Description Language). The original SOFM algorithm was lightly modified for customizing to the hardware

11. Bidirectional Signaling through EphrinA2-EphA2 Enhances Osteoclastogenesis and Suppresses Osteoblastogenesis*S⃞
Bone is remodeled constantly throughout life by bone-resorbing osteoclasts and bone-forming osteoblasts. To maintain bone volume and quality, differentiation of osteoclasts and osteoblasts is tightly regulated through communication between and within these two cell lineages. Previously we reported that cell-cell interaction mediated by ephrinB2 ligand on

12. Excitation–contraction coupling is unaffected by drastic alteration of the sequence surrounding residues L720–L764 of the α1S II-III loop
The II-III loop of the skeletal muscle dihydropyridine receptor (DHPR) α1S subunit is responsible for bidirectional-signaling interactions with the ryanodine receptor (RyR1): transmitting an orthograde, excitation–contraction (EC) coupling signal to RyR1 and receiving a retrograde, current-enhancing signal from RyR1. Previously, several reports argue
