Fast RTP Detection and Codecs Classification in Internet Traffic

Journal of Digital Forensics, Security and Law, 2014
This paper presents a fast multi-stage method for on-line detection of RTP streams and codec identification of transmitted voice or video traffic. The method includes an RTP detector that filters packets based on specific values from UDP and RTP headers.

Excitation‐Dependent Quadruple‐Level Emission from an Isolated Molecule for Dynamic Information Encryption

Advanced Science, EarlyView.
By manipulating the quadruple decoupled radiative transitions of donor and acceptor units, dual‐phase excitation‐dependent afterglow emission is achieved for the first time in a single isolated molecule. The decoupled donor‐acceptor units precisely manipulate the electron transfer pathways in ACRSP, endowing it with intrinsic single‐molecule Ex‐De ...

Evaluation of the diphenyl herbicide, oxyfluorfen, for effects on thyroid hormones in the juvenile rat

Current Research in Toxicology
Recently, oxyfluorfen, a pre- and post-emergent diphenyl ether herbicide, was identified in our laboratory as an inhibitor of iodide uptake by the sodium iodide symporter (NIS), the first key step in the synthesis of thyroid hormones (THs).

Visible‐Light‐Activated Multi‐Color Tunable Time‐Dependent Afterglow Triggered by Variable Conjugation Effects via the Transformation of Matrix

Advanced Science, EarlyView.
Three carbon dots (CDs)‐based composites are synthesized via heat treatment of phenylenediamine derivatives with urea. These composites exhibit time‐dependent afterglow across most of the visible spectrum under visible‐light excitation. The matrix modulation strategy regulates the degree of conjugation in the composites, effectively tuning their ...

A COVERT CHANNEL IN RTP PROTOCOL

Computational Intelligence, 2010
A new covert channel over the RTP protocol is designed and implemented by modifying the timestamp value in the RTP header. Due to the high frequency of RTP packets, the covert channel has a high bit-rate, theoretically up to 350 bps. The broad use of RTP for multimedia applications such as VoIP, provides abundant opportunities to such a covert channel ...

Dendronized Encapsulation with Hierarchical Rigidification Enabling Robust Solution Room‐Temperature Phosphorescence, Efficient Electroluminescence and Ultralong Afterglow

Advanced Science, EarlyView.
The organic RTP's rigidity‐flexibility conflict via multiscale confinement is resolved. Dendronized donor‐acceptor with alkyl carbazoles enables intramolecular encapsulation and stability of triplet excitons, achieving 9 ms solution RTP. Combined with aggregation/PMMA doping, this suppresses nonradiative decay, achieving 72% film PLQY/17.2% OLED EQE ...

Rapid Thermal Processing and Improved Photocatalysis of Bi2O3-BaTiO3 Heterojunction

International Journal of Photoenergy
Bi2O3-BaTiO3 heterojunction with high photocatalysis efficiency was directly synthesized by rapid thermal processing (RTP). Bi2O3 and BaTiO3 were mixed in ratio and treated by RTP and conventional thermal processing (CTP), respectively.

O primeiro

Revista Comunicando, 2017
Éramos numerosos naquela manhã do princípio de junho de 2006 na sala de reuniões do 5o andar da sede da RTP, na Av. Marechal Gomes da Costa. Talvez faltassem dois ou três. Não mais.
