Human-Robot Interaction and especially Human-Robot Communication (HRC) is of primary importance for the development of robots that operate outside production lines and cooperate with humans. In this paper, we review the state of the art and discuss two complementary aspects of the role machine learning plays in HRC. First, we show how communication itself can bene t from learning, e.g. by build...

In this paper an estimation for the performance of QDIP as an element of FSO communication system is given and availiable solutions are compared against the requirements of FSO communication systems. A discussion of QDIP parameters has been presented through theoretical models and experimental data from literature. A relation is proposed for QDIP carrier capture limited modulation bandwith and ...

Background Host immunity is coordinated through a complex network of intercellular communication. Similar to the sculpting of tumor antigens during oncogenesis, a related hypothesis is that proteins secreted by malignant cells are shaped by somatic evolution. Malignant cells that then emerge secrete proteins that alter intercellular communication to promote tumor growth. As exosomes represent a...

We demonstrate for the first time an RFID tag antenna which itself is humidity sensor and also provides calibration functionality. The antenna is comprised of T-matching network and horizontally meandered lines for impedance matching and reliable near-field communication. The novel contour design provides humidity sensing, and calibration functions whilst concurrently acts as a radiating elemen...

In this paper, a large number of studies of the effect of the foliage on single or lines of trees on modern wireless communication systems are reviewed. The paper is focused on the experimental works mainly done for commercial applications such as cellular communication and high speed point-to-point fixed link at the microwave and millimeter wave frequencies. For this review study, the developm...

many characteristic furnace lines which the spark emits very faintly. An outstanding feature of these lines for the iron spectrum is a prevailing large separation and simple triplet structure. Lines of this class are often of special interest in the study of sun-spot spectra. The furnace offers unique facilities for the production of the inverse Zeeman effect when a plug is placed in the tube. ...

ÐGliomas are lethal because of local invasion into brain parenchyma. Glioma cells were isolated from di€erent regions (white matter, gray matter and tumor core) of a glioma-bearing dog brain. Individual clonal cell lines were established from each area, and characterized for growth, migration and gap junctions. The regional clonal cell lines di€ered in rates and preferred substrate for migratio...

we assessed the size and composition of the soil seed bank and above-ground vegetation in 52 relevés representing a range of habitats within an old- growth, temperate deciduous forest at hyrcanian region, northern iran. we identified 63 taxa in the seed bank, with an average density of 4202 seeds/spores per m2 by seedling emergence method. hypericum androsaemum, cardamine impatiens, and rub...

objective(s): artemisia is a genus of herbs and small shrubs forms an important part of natural vegetation in iran. it has been reported that several artemisia species possess anti-proliferative effects. considering the value of this genus in anti-cancer researches we have chosen artemisia biennis for cytotoxic and mechanistic studies. materials and methods:in this study we have investigated th...

Gap junctional intercellular communication (GJIC) regulates cellular homeostasis by propagating signaling molecules, exchanging cellular metabolites, and coupling electrical signals. In cancer, cells exhibit altered rates of GJIC which may play a role in neoplastic progression. K(ATP) channels help maintain membrane polarity and linkages between K(ATP) channel activity and rates of GJIC have be...
