In this paper, a novel multilink selection framework is developed for different applications with various quality of service (QoS) requirements in avionic systems, based on the multi-attribute decision-making model. Two metaheuristic algorithms are proposed to solve model while optimizing performances. Multilink configuration and multi-homing capabilities generally required aircrafts operating ...

In this paper, they study energy efficient resource allocation scheme for Orthogonal Frequency Division Multiple Access (OFDMA) systems with heterogeneous users. The trade-off between spectral and energy efficiencies is analyzed under the constraint of maintaining the fairness among users. They formulate the energy-efficient optimization problem as an integer fractional programming and present ...

I study two-sided markets where the platform is composed of components supplied by di¤erent producers. I examine a producer’s incentive to provide compatibility of its product with other suppliers’. Two models are considered. In the …rst model, I …nd that tying of a complementary product may be pro…table. In the second model, I …nd that a durable goods monopolist’s introduction of incompatibili...

As emphasised in a series of recent articles (2), the two(or multi-)sided nature of a market should explicitly be considered in evaluating the existence and magnitude of possible anti-competitive effects. However, the relevance of the two-sided nature of markets depends on at least two elements: (i) indirect network externalities and (ii) pattern of subscription (‘homing’) to the platform. Unde...

Distinct groups of innate lymphoid cells (ILCs) such as ILC1, ILC2, and ILC3 populate the intestine, but how these ILCs develop tissue tropism for this organ is unclear. We report that prior to migration to the intestine ILCs first undergo a "switch" in their expression of homing receptors from lymphoid to gut homing receptors. This process is regulated by mucosal dendritic cells and the gut-sp...

Tumor homing peptides are small peptides that home specifically to tumor and tumor associated microenvironment i.e. tumor vasculature, after systemic delivery. Keeping in mind the huge therapeutic importance of these peptides, we have made an attempt to analyze and predict tumor homing peptides. It was observed that certain types of residues are preferred in tumor homing peptides. Therefore, we...

Tissue-specific homing of effector and memory T cells to skin and small intestine requires the imprinting of specific combinations of adhesion molecules and chemokine receptors by dendritic cells in the draining lymph nodes. In this study, we demonstrate that CD8 T cells activated by Ag-pulsed bone marrow-derived dendritic cells were induced to express the small intestine homing receptors 4 7 i...

Homing pigeons (Columba livia f.d.) are well-known for their homing abilities, and their brains seem to be functionally adapted to homing as exemplified, e.g. by their larger hippocampi and olfactory bulbs. Their hippocampus size is influenced by navigational experience, and, as in other birds, functional specialisation of the left and right hemispheres ('lateralisation') occurs in homing pigeo...

Some features of SCTP provide opportunities for creating redundancies for signalling over IP networks. This paper presents the behaviour of SCTP in failover scenarios, based on literature review and simulations. Simulations were carried out using NS2 in a multi-homing environment. It was found, as expected, that when failover took place, the undelivered chunks were retransmitted to the secondar...

In this paper, a new SCTP congestion control mechanism is introduced in multi-homing mode. Congestion in each route can be avoided or can be controlled, based on an Active Queue Management (AQM) method. Also, routers compute probability of congestion for the sources on the paths and then notify them. Therefore, the sources can adjust their sending rates on each path effectively and if necessary...
