(TUBITAK, 2019)We establish a characterization of the Lyapunov and Mittag-Leffler stability through (fractional) Lyapunov functions, by proving converse theorems for Caputo fractional order systems. A hierarchy for the Mittag-Leffler ...
-
(MDPI AG, 2019)In this paper, a deep learning (DL)-based physical (PHY) layer authentication framework is proposed to enhance the security of industrial wireless sensor networks (IWSNs). Three algorithms, the deep neural network (DNN)-based ...
-
(Elsevier Inc., 2019)Surface texturing is a promising approach to tailor friction and wear between rubbing surfaces in mechanical components. In this study, surface textures with different geometries and shapes were fabricated on hardened steel ...
-
(MDPI AG, 2019)Dehydration in rodents induces anorexia. In humans however, the role of dehydration in energy intake is controversial. This study investigated the effect of extreme fluid restriction on acute energy intake during and after ...
-
(Elsevier GmbH, 2019)Background: Dendritic cells (DCs) are usually immunogenic, but they are also capable of inducing tolerance under anti-inflammatory conditions. Immunotherapy based on autologous DCs loaded with an allogeneic melanoma cell ...
-
(Institute of Physics Publishing, 2019)The Cosmology Large Angular Scale Surveyor (CLASS) is mapping the polarization of the cosmic microwave background (CMB) at large angular scales (2 < ℓ ≲ 200) in search of a primordial gravitational wave B-mode signal ...
-
(Lippincott Williams and Wilkins, 2019)Background:Adaptive immunity is crucial in cardiovascular and renal inflammation/fibrosis upon hyperactivation of mineralocorticoid receptor. We have previously demonstrated that dendritic cells can respond to mineralocorticoid ...
-
