Published in 2019 at "Advanced Optical Materials"

DOI: 10.1002/adom.201901048

Abstract: Organic light‐emitting devices (OLEDs) are widely used for mobile displays, but the relatively short lifetime of blue OLEDs remains a challenge in many applications. Typically, instability is viewed as a material‐specific chemical degradation problem. It… read more here.

Published in 2018 at "Journal of High Energy Physics"

DOI: 10.1007/jhep11(2018)014

Abstract: A bstractThe lifetimes of bottom and charmed hadrons are analyzed within the framework of the heavy quark expansion (HQE). Lifetime differences arise from the spectator effects such as weak W-annihilation and Pauli interference. Spectator effects… read more here.

Published in 2020 at "Statistical Papers"

DOI: 10.1007/s00362-017-0968-7

Abstract: We study a type of double truncation where units are observed if and only if their death event occurs within a specific timespan. The resulting missing data mechanism is nonignorable and thus has to be… read more here.

Published in 2018 at "Journal of Materials Science: Materials in Electronics"

DOI: 10.1007/s10854-018-0506-y

Abstract: Electromigration (EM) is the mass transport of atoms due to electron flow, which induces a disconnect in electronic packaging. Recently, EM has received growing attention because it occurs easily when the size of joints in… read more here.

Published in 2017 at "Mobile Networks and Applications"

DOI: 10.1007/s11036-017-0861-6

Abstract: Lifetime enhancement has been the major constraint of developing wireless sensor networks (WSNs). Most of previous related works separately considered dynamics and heterogeneity of WSNs, and did not consider energy-harvesting (EH) sensors, which can absorb… read more here.

Published in 2020 at "Ad Hoc Networks"

DOI: 10.1016/j.adhoc.2019.101994

Abstract: Abstract Wireless Sensor Networks (WSNs) consist of a set of devices with limited energy capacity, therefore the longevity of the network can be one of the decisive quality parameters of WSNs. We study the problem… read more here.
