Recapitulating In Vivo Pharmacokinetics and Size-Dependent Nanomedicine Delivery in a Microfluidic Platform. [PDF]

open access: yesAdv Sci (Weinh)
A microfluidic tumor platform integrates pharmacokinetic flow control, vascular‐like barriers, and 3D tumor spheroids to emulate in vivo drug exposure. The system reproduces dynamic concentration–time profiles and enables size‐dependent nanoparticle transport and efficacy evaluation, providing a predictive framework for assessing nanomedicine ...

Hederagenin Attenuates Morphine Addiction via GABAA1-Mediated Modulation of Ca<sup>2</sup> <sup>+</sup>-CaMK-CREB Signaling in Ventral Tegmental Dopaminergic Neurons. [PDF]

open access: yesAdv Sci (Weinh)
Hederagenin is identified as a GABAA1‐targeting natural compound that suppresses morphine‐associated reward by restraining Ca2+–CaMK–cAMP–CREB signaling in ventral tegmental dopaminergic neurons. RVG29‐modified liposomal delivery further enhances brain accumulation and behavioral efficacy, providing a mechanistically defined strategy for natural ...

COLLADA + MPEG-4 OR X3D + MPEG-4 [PDF]

open access: yesIEEE Vehicular Technology Magazine, 2010
The paper is an overview of 3D graphics assets and applications standards.The authors analyzed the three main open standards dealing with three-dimensional (3-D) graphics content and applications, X3D, COLLADA, and MPEG4, to clarify the role of each with respect to the following criteria: ability to describe only the graphics assets in a synthetic 3-D ...

Transcoding of MPEG bitstreams [PDF]

open access: yesSignal Processing: Image Communication, 1996
This paper discusses the problem of transcoding as it may occur in, for instance, the following situation. Suppose a satellite transmits an MPEG-compressed video signal at say 9 Mbit/s. This signal must be relayed at a cable head end. However, since the cable capacity is only limited, the cable head end will want to relay this incoming signal at a ...

Optimal packetisation of MPEG-4 using RTP over mobile networks [PDF]

open access: yes, 2001
The introduction of third-generation wireless networks should result in real-time mobile video communications becoming a reality. Delivery of such video is likely to be facilitated by the realtime transport protocol (RTP).

Enriching MPEG-7 user models with content metadata [PDF]

open access: yes, 2006
MPEG-7 is an XML-based standard that provides tools for creating rich and structured multimedia content metadata. However, only an extremely limited range of preferences can be specified for user models and multimedia content metadata created by other ...

MPEG-7 camera [PDF]

open access: yesProceedings 2001 International Conference on Image Processing (Cat. No.01CH37205), 2002
An MPEG-7 camera extends the capabilities of conventional cameras by analyzing its scene in order to generate a content-based description according to the recently approved MPEG-7 standard. This gives to the camera a large variety of current and potential applications, such as surveillance, augmented reality, and virtual display. This paper provides an

Aggregated feature retrieval for MPEG-7 [PDF]

open access: yes, 2003
In this paper we present an initial study on the use of both high and low level MPEG-7 descriptions for video retrieval. A brief survey of current XML indexing techniques shows that an IR-based retrieval method provides a better foundation for retrieval ...
