Recently researchers have identified several short, α-helical peptide sequences that are capable of transporting large protein cargo or hydrophilic molecules such as dyes or drugs through the lipid bilayer into cells. These peptides, known as cellpermeable peptides or transduction peptides, have found applications in both basic research and therapeutic purposes. However, peptides are expensive ...

The deployment of a high speed, wide area ATM network introduces a “backwards compatibility” dilemma. While emerging ATM networks must be capable of transporting traffic sources such as digital voice and video, many of the design choices that optimize ATM for voice and video make the transport of traditional connectionless data traffic difficult. This paper proposes the overlay of a virtual dat...

Background Transporting critically ill patients between hospitals may be hazardous. Treatment of medical emergencies is paramount, and delivery of drugs during a medical emergency on patient transport may be lifesaving. Currently, there is no standardized crash cart and no guidelines on which drugs physicians should bring when escorting patients. There is increasing evidence that system differe...

In this paper, we consider the problem of controlling multiple quadrotor robots that cooperatively grasp and transport a payload in three dimensions. We model the quadrotors both individually and as a group rigidly attached to a payload. We propose individual robot control laws defined with respect to the payload that stabilize the payload along three-dimensional trajectories. We detail the des...

An analog fiber-optic link transporting the wireless code-division multiple-access (CDMA) signals requires the minimum dynamic range of only about 30 dB. Motivated by this relaxed requirement, we have recently proposed a passive optical network for CDMA-based microcellular communication systems. In this paper, we reviewed the basic design rules and demonstrated various networks using double-sta...

Household manipulation presents a challenge to robots because it requires perceiving a variety of objects, planning multi-step motions, and recovering from failure. This paper presents practical techniques that improve performance in these areas by considering the complete system in the context of this specific domain. We validate these techniques on a table-clearing task that involves loading ...

The growth of Asynchronous Transfer Mode (ATM) technology and the maturity of coding standards have made the large-scale deployment of high-quality audiovisual services possible. In this article, we discuss the principal issues involved in transporting MPEG-2 streams over ATM networks for both constant bit-rate (CBR) and variable bit-rate (VBR) MPEG-2 Transport Streams. We review existing and p...

A novel ambipolar spiro-configured D-A blue-light emitter bearing hole-transporting diphenylamino groups and electron-transporting phenylbenzimidazole groups was synthesized, characterized, and incorporated into an efficient single-layer organic light-emitting diode (OLED) device exhibiting blue-emission Commission International d'Eclairage (CIE) coordinates of 0.15 and 0.14, a turn-on potentia...

the selection of optimum support system is a key step in the successful design operation of tunneling, rock mass stabilization and minimization of plastic zone extension around a tunnel. in this context, it is not sufficient to rely only on the experiences of design engineers, but taking all effective measures and parameters is necessary to do a proper choice. in this paper, multi attribute dec...
