RAM function is dependent on Kapβ2-mediated nuclear entry
No full textEukaryotic gene expression is dependent on the modification of the first transcribed nucleotide of pre-mRNA by the addition of the 7-methylguanosine cap. The cap protects transcripts from exonucleases and recruits complexes which mediate transcription elongation, processing and translation initiation. The cap is synthesised by a series of reactions which link 7-methylguanosine to the first transcribed nucleotide via a 5' to 5' triphosphate bridge. In mammals, cap synthesis is catalysed by the sequential action of RNGTT (RNA guanylyltransferase and 5'-phosphatase) and RNMT (RNA guanine-7 methyltransferase), enzymes recruited to RNA pol II during the early stages of transcription. We recently discovered that the mammalian cap methyltransferase is a heterodimer consisting of RNMT and the RNMT-activating subunit, RAM (RNMT-activating mini-protein). RAM activates and stabilises RNMT and thus is critical for cellular cap methylation and cell viability. Here we report that RNMT interacts with the N-terminal 45 amino acids of RAM, a domain necessary and sufficient for maximal RNMT activation. In contrast, smaller components of this RAM domain are sufficient to stabilise RNMT. RAM functions in the nucleus and we report that nuclear import of RAM is dependent on PY nuclear localisation signals and Kapß2 nuclear transport protein

Numerical simulation of ram extrusion in short-fiber-reinforced fresh cementitious composites
No full textThis is the author's accepted manuscript. The final published article is available from the link below. First published in JoMMS in 4(10), 2009, published by Mathematical Sciences Publishers.A series of ram extrusion tests was carried out on a short-fiber-reinforced, semisolid, fresh cementitious composite. An elastoviscoplastic constitutive model is proposed for the extrudable fresh cementitious composite. It features the associative flow rule, a nonlinear strain rate-hardening law, and the von Mises yield criterion. The model is then implemented in ANSYS/LS-DYNA explicit finite element code.
Various ram extrusion processes of the fresh cementitious composite were simulated. It has been found that the extrusion load versus imposed displacement predictions agree well with the experimental results. The fresh paste flow, through the die entry and the die-land, is then interpreted in light of the evolution of the deformation and distribution of state variables, mainly based on numerical results and the ram extrusion mechanism.
The effects of extrusion ratio and extrusion velocity on extrusion load are also investigated, based on the mechanical properties of the fresh cementitious composite. The study indicates that the numerical procedure established, together with the constitutive model proposed, is applicable for describing ram extrusion of short-fiber-reinforced fresh cementitious composites, which might provide a numerical rheometric tool from which ram extrusion of elastoviscoplastic paste-like materials can be examined and quantified.Hong Kong Research Grant Council and China Ministry of Science and Technology
Two degree of freedom motion control of an energy optimized aircraft ram air inlet actuators
No full textA high accurate position control structure for energy optimal actuation of an aircraft ram air inlet actuator is presented in this paper. The structure comprises a feedforward planning of the energy optimal reference motion profile, and a feedback position control with an inner loop for speed tracking control using a robust two degree of freedom (inverse disturbance observer) controller. The motion control structure is validated by simulation and experimental results under different load conditions
Design of NML Circuits based on M-RAM
No full textNanoMagnet Logic (NML) is an emerging technol- ogy that allows to design digital circuits using nanomagnets. Each magnet has only two possible states and encodes digital informa- tion without the need for currents or voltages. This behavior differentiates NML circuits from charge based technologies. The advantages provided by NML circuits are a possible very low power consumption, and the ability to mix logic and memory in the same device. While a rich experimental activity on NML circuits can be found in literature, the feasibility of a complete NML system remains to be demonstrated yet. In this work we explore the possibility of implementing NML logic circuits based on the physical structure of Magnetic RAM (M-RAM). The advantages are twofold: First, M-RAM is a well developed technology, ready for the commercial stage, second it intrinsically provides an interface toward the CMOS world. To demonstrate the feasibility of NML circuits based on M-RAM we have designed a 3-input Ex-OR gate, using two different physical layouts for control signals. The first solution is strictly based on the M-RAM structure; the second solution requires a more complex fabrication process but leads to a smaller area. Circuits are simulated using VHDL language, with the aid of a tool that we have developed which automatically generates the VHDL code starting from the circuit layout. Overall, the solution here presented is a considerable step-forward toward the development of a complete magnetic circui
The Athlit Ram: Classical and Hellenistic bronze casting technology
No full textDue to the character of the original source materials and the nature of batch digitization, quality control issues may be present in this document. Please report any quality issues you encounter to [email protected], referencing the URI of the item.Includes bibliographical references (leaves 95-103).Issued also on microfiche from Lange Micrographics.In 1980 a warship ram of bronze was discovered at Athlit Bay, south of Haifa, Israel. The subsequent study of the ram added significantly to the knowledge concerning Classical and Hellenistic large-scale bronzes. The Athlit ram far exceeds other existing rams in size and is one of the largest bronzes to have survived intact from the ancient Mediterranean world. Initial metallographic and metallurgical analyses of the ram, made shortly after its recovery, led to the conclusion that it was cast horizontally as a single piece in a two-part sandbox. However, the use of this casting method, commonly referred to as sand-casting, has not been documented prior to the late Medieval period. Such a conclusion is therefore inconsistent with existing knowledge of Classical and Hellenistic bronze casting technology. Through the use of advanced analytical techniques and careful visual examination, the current study re-evaluates the technology employed in casting the Athlit ram. Newly gathered data, complemented with archaeological evidence from foundry remains and other surviving bronzes, indicate a close technical correlation between the methods used to produce the ram and the techniques used to create contemporary bronze sculptures. With reference to ancient literary sources and modern technical studies, the current work attempts to reconstruct the casting sequence used. The conclusions place the Athlit ram comfortably within the known parameters of Classical and Hellenistic foundry practices. This study suggests that the ram was cast using the lost-wax technique and speculates about the adaptation of this casting method in order to use the bow timbers of the ship as a temporary core on which to build the wax model, thereby more efficiently fulfilling the design requirements of the ram
A One Transistor RAM for MPC Projects
No full textMany MPC projects, such as video frame buffers, need a large memory subsystem. A one transistor per bit dynamic memory using Mead-Conway design rules is being designed with this purpose in mind. The memory cell size is 16.5 λ by 8λ (about the same size as a 1975 4K RAM cell with λ = 2.5 microns).
While a complete high density memory subsystem has not been designed, two chips have been designed to test its major components. One chip is a 1K memory array that tests the sense amplifier, column decoder/driver, and read/write logic. This chip lacks a timing generator and clock drivers. The second chip tests some low power bootstrapped clock drivers. These test chips are currently being fabricated
