Konferensbidrag (refereegranskat)abstract
- A ±45° dual-polarized antenna is designed based on the gap waveguide technology which offers a low loss and easy-to-manufacture solution at the mmWave frequencies. Dual-polarized antennas help to increase the capacity and coverage of a wireless system and also decrease the overall cost. Two parallel arrays of 8 slots each are employed to create the orthogonal polarizations. The antenna operates in the 24.25 - 27.25 GHz frequency band. The simulated average gain of each polarization is 14.5 dBi while achieving a cross-polarization isolation of at least 15 dB.

A New Calibration Kit for VNA Measurements of General Microstrip Line Devices Using Gap Waveguide Technology
- 2018
-
Ingår i: ISAP 2018 - 2018 International Symposium on Antennas and Propagation.
-
Konferensbidrag (refereegranskat)abstract
- A new calibration kit for VNA Measurements of general microstrip line devices is presented. The proposed calibration kit and test fixture is based on a gap waveguide to microstrip transition which can provide an interface for measurements on microstrip line devices with low influence on the DUT performance due to its compact size.

Sensory Stimulation and Oxytocin : Their Roles in Social Interaction and Health Promotion

- The aim of this call was to collect papers describing how oxytocin may be released by different kinds of sensory stimulation to induce wellbeing and restorative processes and to inhibit pain, stress and inflammation. A large number of interesting articles of very high quality were received and 19 papers were accepted for publication. All the included articles have contributed to expand the knowledge about oxytocin in a very substantial way both regarding its effect spectrum and regarding its association with sensory, somatosensory stimulation, in particular. In fact, the obtained data contribute to prove the hypothesis that the oxytocinergic system is a widespread integrative system, which is linked to social interaction, wellbeing, reduction of stress and pain as well as to reproductive, growth promoting and restorative effects. The activity of this archaic oxytocin system is under control of hormones and sensory nerves, which convey information regarding the state of the internal and the external environment. The oxytocin linked effects may be induced in the short-term as well as in the long-term perspective. All of the articles which were accepted and included in this issue, in their own unique way, contribute to describe oxytocin beyond its classical role in birth and milk ejection in accordance with the concept described above. We describe and discuss the data after having categorized the results presented in the articles according to certain subjects.

Vanilloid receptors on sensory nerves mediate the vasodilator action of anandamide

- The endogenous cannabinoid receptor agonist anandamide is a powerful vasodilator of isolated vascular preparations, but its mechanism of action is unclear. Here we show that the vasodilator response to anandamide in isolated arteries is capsaicin-sensitive and accompanied by release of calcitonin- gene-related peptide (CGRP). The selective CGRP-receptor antagonist 8-37 CGRP (ref. 5), but not the cannabinoid CB1 receptor blocker SR141716A (ref. 7), inhibited the vasodilator effect of anandamide. Other endogenous. (2- arachidonylglycerol, palmitylethanolamide) and synthetic (HU 210, WIN 55,212- 2, CP 55,940) CB1 and CB2 receptor agonists could not mimic the action of anandamide. The selective 'vanilloid receptor' antagonist capsazepine inhibited anandamide-induced vasodilation and release of CGRP. In patch-clamp experiments on cells expressing the cloned vanilloid receptor (VR1), anandamide induced a capsazepine-sensitive current in whole cells and isolated membrane patches. Our results indicate that anandamide induces vasodilation by activating vanilloid receptors on perivascular sensory nerves and causing release of CGRP. The vanilloid receptor may thus be another molecular target for endogenous anandamide, besides cannabinoid receptors, in the nervous and cardiovascular systems.
