On the K and KG fading channels [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2009
In this paper, the composite Rayleigh-Gamma and Nakagami-Gamma distributions are considered. Multipath short-term fading and long-term fading (shadowing) affect wireless channels.

High-speed braking properties of Cu-based powder metallurgy brake pads

open access: yesFenmo yejin jishu, 2023
Friction coefficients of the Cu-based powder metallurgical brake pads decline due to the high temperature during the high-speed braking, which will directly affect the train braking effectiveness.

Exploring types of individual unlearning by local health-care managers: an original empirical approach

open access: yesHealth Services and Delivery Research, 2013
Background: The ability of health-care managers or organisations to adapt and respond to change is vital if they are to succeed in the contemporary health-care environment. Change involves the learning of new behaviours and giving up, or abandoning, some

Development of Ag-Doped ZnO Thin Films and Thermoluminescence (TLD) Characteristics for Radiation Technology

open access: yesNanomaterials, 2022
This work examined the thermoluminescence dosimetry characteristics of Ag-doped ZnO thin films. The hydrothermal method was employed to synthesize Ag-doped ZnO thin films with variant molarity of Ag (0, 0.5, 1.0, 3.0, and 5.0 mol%).

Fading ergodicity

open access: yesPhysical Review B
Eigenstate thermalization hypothesis (ETH) represents a breakthrough in many-body physics since it allows us to link thermalization of physical observables with the applicability of random matrix theory (RMT). Recent years were also extremely fruitful in exploring possible counterexamples to thermalization, ranging, among others, from integrability ...

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

FEC-Assisted PAPR Reduction in OFDM System—Performance Analysis

open access: yesIEEE Access
As 6G standardization continues, Orthogonal Frequency Division Multiplexing (OFDM) continues to be the preferred waveform due to its spectral efficiency and robustness against multipath fading.
