From aggregation-induced emission to organic room temperature phosphorescence through suppression of molecular vibration

open access: yesCell Reports Physical Science, 2022
Summary: With the rapid development of aggregation-induced emission (AIE), the principles of AIE have also been shown to stimulate the design of organic room temperature phosphorescence (RTP). Without reverting to heavy covalent synthesis, suppression of

Application-driven network management with ProtoRINA [PDF]

open access: yes, 2015
Traditional network management is tied to the TCP/IP architecture, thus it inherits its many limitations, e.g., static management and one-size-fits-all structure.

Automatic Segmentation of Anatomical Structures from CT Scans of Thorax for RTP

open access: yesComput. Math. Methods Medicine, 2014
Modern radiotherapy techniques are vulnerable to delineation inaccuracies owing to the steep dose gradient around the target. In this aspect, accurate contouring comprises an indispensable part of optimal radiation treatment planning (RTP).

Effects of Varying Deposition Rates of a Carbazole and Triazine Derivative on Its Tunable Emission and Charge‐Transporting Properties Beneficial for Efficient Red Electroluminescent Devices

open access: yesAdvanced Optical Materials, EarlyView.
The highly efficient and ultrafast thermally activated delayed fluorescence (TADF) behavior of the bipolar derivative of carbazole and triazine stems from the high‐lying triplet states (hot TADF), which has a direct impact on the overall triplet harvesting of guest‐host mixtures.

Congestion Control using FEC for Conversational Multimedia Communication

open access: yes, 2013
In this paper, we propose a new rate control algorithm for conversational multimedia flows. In our approach, along with Real-time Transport Protocol (RTP) media packets, we propose sending redundant packets to probe for available bandwidth.

Building self-optimized communication systems based on applicative cross-layer information [PDF]

open access: yes, 2008
This article proposes the Implicit Packet Meta Header(IPMH) as a standard method to compute and represent common QoS properties of the Application Data Units (ADU) of multimedia streams using legacy and proprietary streams’ headers (e.g.

LC-RTP (loss collection RTP): reliability for video caching in the Internet [PDF]

open access: yesProceedings Seventh International Conference on Parallel and Distributed Systems: Workshops, 2000
The increasing amount of audio-visual (AV) content that is offered by web sites leads to a network bandwidth and storage capacity problem. Caching is one of the techniques that can ease this problem. But even in a caching system the distribution of data (i.e. the AV content) should be bandwidth-efficient.

Coupled congestion control for RTP media

open access: yesCSWS@SIGCOMM, 2014
Congestion occurs at a bottleneck along an Internet path; multiple flows between the same sender and receiver pairs can benefit from using only a single congestion control instance when they share the same bottleneck.

Butterfly‐Shaped Guest Molecules Enable Tunable Room‐Temperature Phosphorescence in Host‐Guest Doped Systems

open access: yesAdvanced Science, EarlyView.
Butterfly‐shaped triphenylamine‐based guest molecules (DBDBD) doped into rigid host matrices (TPP, CA) achieve efficient, multicolor‐tunable room‐temperature phosphorescence (RTP). The host‐guest synergy enables ultralong afterglow (up to 4 s) and quantum yields (Φp = 3.42%), with applications in dynamic anti‐counterfeiting and information encryption ...
