Note-pad computers and the concept of Electronic Paper (1991)

Computers have become extremely important in most functions of modern business activity. Their optimal exploitation, however, can currently be achieved only if the staff who operate them are prepared to adapt to the machines. Human Computer Interface (HCI) research aims to reduce this human adaptat ion and produce a more “user natural” environment. One approach particularly relevant to business and management staff is Electronic Paper (EP) since it enables untutored staff to utilise powerful computer facilities without the need for specialised computer training and understanding. This paper describes the concept of EP and some typical applications that are practical now and in the future. The historical development and current state of the technology required to produce successful EP devices are also discussed. A list of key commercial systems is provided. Computer technology is continually improving and is at the stage where a practical EP system is now achievable. This will eventually combine with intelligent applications software and cursive script recognition (CSR) to give a comprehensive EP system.

Yeast ASF1 Protein Is Required for Cell Cycle Regulation of Histone Gene Transcription (2001)

Transcription of the four yeast histone gene pairs (HTA1-HTB1, HTA2-HTB2, HHT1-HHF1, and HHT2-HHF2) is repressed during G1, G2, and M. For all except HTA2-HTB2, this repression requires several trans-acting factors, including the products of the HIR genes, HIR1, HIR2, and HIR3. ASF1 is a highly conserved protein that has been implicated in transcriptional silencing and chromatin assembly. In this analysis, we show that HIR1 interacts with ASF1 in a two-hybrid analysis. Further, asf1 mutants, like hir mutants, are defective in repression of histone gene transcription during the cell cycle and in cells arrested in early S phase in response to hydroxyurea. asf1 and hir1 mutations also show very similar synergistic interactions with mutations in cac2, a subunit of the yeast chromatin assembly factor CAF-I. The results suggest that ASF1 and HIR1 function in the same pathway to create a repressive chromatin structure in the histone genes during the cell cycle.
Leaky-wave multiple dichroic beam formers (1989)

The beamforming action of three planar frequency-selective surfaces (FSSs) placed in front of a waveguide aperture in a ground plane is demonstrated experimentally, together with the application to printed antennas. A simple ray theory illustrates the leaky-wave action for one FSS in position and the advantages and disadvantages of this beamforming technique are noted.
Acceleration of real-life stencil codes on GPUs (2011)

Among the compute intensive applications, the FDTD (Finite-Difference-Time-Domain) allows to solve time-dependent differential equations. This method is commonly used in electromagnetism to find solutions to Maxwell equations. Although considered as powerful and flexible, the FDTD algorithm has the disadvantage of having a huge numerical dispersion due to nested loops, which are loops inside other loops in the same program. Therefore, the execution time required for such methods is often prohibitive, particularly when the number of loop iterations is large, or when coupled with global optimization algorithms such as genetic algorithms \cite{genetic}. Nevertheless, there exist some program transformations techniques, such as loop tiling, that can be applied on code, precisely on nested loops, in order to improve its execution time on parallel architectures. This is done by dividing computations into independent blocks, then assigning each block to a processor within a parallel machine. Loop tiling transformation is particularly appropriate for GPUs, because they are massively parallel and powerful. During our internship, we have focused on how to optimize the execution of a FDTD-based application developed by Rolland et al. on GPUs, by applying such transformation. In this report, Section 2 describes the context of the internship by presenting, in general, our target application and reviews the CUDA programming model and loop tiling transformation. Section 3 deals with the recent works related to FDTD on GPUs. Section 4 describes in detail the FDTD algorithm of the target application, and presents the different approaches of loop tiling transformation that can be applied on it.
Retinoic acid response element in the human alcohol dehydrogenase gene ADH3: implications for regulation of retinoic acid synthesis. (1991)

Retinoic acid regulation of one member of the human class I alcohol dehydrogenase (ADH) gene family was demonstrated, suggesting that the retinol dehydrogenase function of ADH may play a regulatory role in the biosynthetic pathway for retinoic acid. Promoter activity of human ADH3, but not ADH1 or ADH2, was shown to be activated by retinoic acid in transient transfection assays of Hep3B human hepatoma cells. Deletion mapping experiments identified a region in the ADH3 promoter located between -328 and -272 bp which confers retinoic acid activation. This region was also demonstrated to confer retinoic acid responsiveness on the ADH1 and ADH2 genes in heterologous promoter fusions. Within a 34-bp stretch, the ADH3 retinoic acid response element (RARE) contains two TGACC motifs and one TGAAC motif, both of which exist in RAREs controlling other genes. A block mutation of the TGACC sequence located at -289 to -285 bp eliminated the retinoic acid response. As assayed by gel shift DNA binding studies, the RARE region (-328 to -272 bp) of ADH3 bound the human retinoic acid receptor beta (RAR beta) and was competed for by DNA containing a RARE present in the gene encoding RAR beta. Since ADH catalyzes the conversion of retinol to retinal, which can be further converted to retinoic acid by aldehyde dehydrogenase, these results suggest that retinoic acid activation of ADH3 constitutes a positive feedback loop regulating retinoic acid synthesis.
Zonal-Isolation Barriers Meet Valhall Waterflooding, Fracturing Demands (2009)

Technology Update The Valhall field, operated by BP Norge in the Norwegian North Sea, is undergoing a massive redevelopment that will allow the field to keep producing until approximately 2050. With the field undergoing waterflooding, the operator is investigating strategies to prevent formation damage that could result from a waterflood and to minimize costs as the redevelopment program progresses. The reservoir-management plan relies on multiple-zone water injection, with management of offset water in the producing wells controlled by heavy-duty sliding sleeves. Proppant fracture stimulation of the production wells requires high-differential-pressure isolation between zones. Cementing of the reservoir liner normally provides this isolation between the producing zones, but the presence of cement can render the sliding sleeves inoperable. The use of zonal-isolation-barrier (ZIB) devices that were developed by READ Well Services was identified as a potential solution for meeting the isolation requirements of the producing wells and was implemented, marking the industry's first use of this, specific ZIB technology (Fig. 1). This alternative approach was deemed necessary to limit the risk of damaging the sliding sleeves and reduce other operating risks, when compared with the established practice of running and cementing the reservoir liner. ZIB devices possess the advantages of both cement and mechanical barriers, such as packers, in executing zonal isolations, but without the operational risks associated with these traditional technologies. The basic principle of the ZIB technology is that when pressure is applied to the inside of the liner, the metal outer sleeve will inflate and conform to the profile of the formation. If required, the ZIB can also be expanded in the future—for example, should a washout or water breakthrough occur. The ZIB can be activated by applying pressure from the surface to the entire completion or by deploying a hydraulic-expandable-tubular-system tool by means of wireline, coiled tubing, or drillpipe (Fig. 2). Nine ZIB devices have now been deployed at Valhall with 65/8-in. liners, providing open-hole zonal isolation during fracturing and production operations.
PERFORMANCE OF A MULTISTAGE CENTRIFUGAL CONTACTOR (1963)

A five-stage centrifugal contactor with 10-inch-diameter stages processed natural or enriched uranium solutions by solvent extraction. High mass transfer efficiencies for uranium were attained at total flow rates of at least 40 and 60 gpm, respectively. The unit had a hydraulic capacity in excess of 60 gpm with undiluted tri-n-butyl phosphate as the solvent, provided the aqueous phase contained at least 3M HNO/sub 3/. (auth)
High Frequency Electric Glass Welding (1941)

The use of redox flow batteries (RFBs) has become popular for preserving renewable energy. For widespread commercialization, the appropriate selection of redox-active species and ion exchange membranes (IEM) is essential. Herein, we synthesized a robust PVA-Silica (PVA-SiO2) composite membrane and demonstrated its essential use in an aqueous hybrid RFB. A proton-conducting, chemically and physically stable membrane was created by combining the traditional hydrophilicity of PVA with well-defined interconnecting ion-conducting channels produced by uniformly distributed silica particles. We believe that thermal crosslinking ensured substantial dimensional and chemical durability, whereas silica permitted good ionic conductivity. The utility of the membrane was proved in a hybrid redox flow battery consisting of newly synthesized 1,4-phenoxy bis-propane sulfonic acid (PPS) and vanadium (III) salt in 2 M H2SO4. A detailed battery analysis was carried out with a rate performance study, cycling test, polarization curve, and OCV. Over 100 charge/discharge cycles, it demonstrated 95% coulombic efficiency, 61% voltage efficiency, and 57% energy efficiency at a current density of 50 mA cm-2, indicating the best utility of an oxidatively susceptible functional group-free robust proton conducting membrane.
Spoken Conversational AI in Video Games (2018)

In a traditional role-playing game (RPG) conversing with a Non-Playable Character (NPC) typically appears somewhat unrealistic and can break immersion and user engagement. In commercial games, the player usually selects one of several possible predefined conversation options which are displayed as text or labels on the screen, to progress the conversation. In contrast, we first present a spoken conversational interface, built using a state-of-the-art open-domain social conversational AI developed for the Amazon Alexa Challenge, which was modified for use in a video game. This system is designed to keep users engaged in the conversation -- which we measure by time taken speaking with the character. In particular, we use emotion detection and emotional dialogue management to enhance the conversational experience. We then evaluate the contribution of emotion detection and conversational responses in a spoken dialogue system for a role-playing video game. In order to do this, two prototypes of the same game were created: one system using sentiment analysis and emotional modelling and the other system that does not detect or react to emotions. Both systems use a spoken conversational AI system where the user can freely talk to a Non-Playable-Character using unconstrained speech input.
Development of the Semi-Active Suspension System Based on the Sky-Hook Damper Theory (1994)

<div class="htmlview paragraph">A semi-active suspension system is a system in which the damping coefficient of the suspension damper is controlled actively. This type of system exhibits high performance while having low system cost, light system weight, and low energy consumption. From this viewpoint, the semi-active suspension system is greatly expected to be in the mainstream of future suspension control systems.</div> <div class="htmlview paragraph">In this paper, several important points for realizing a semi-active suspension system based on the Sky-hook damper theory will be explained. At the same time, an example of the system developed by us, where the Sky-hook damper has been realized by a simple system configuration, will be shown.</div>

Autonomous Underwater Vehicles for Port Protection (2006)

NATO’s present capability to deal with a terrorist threat to our ports is slow, dangerous, and inefficient. Ports are a challenging area within which to conduct MCM operations due to several factors: shipping movements, very shallow water, turbidity, confined space, mine burial due to muddy/silty conditions, and high clutter density. The shortfall in NATO’s ability to deal with this problem has been recognised by NATO Strategic Commanders who gave the highest priority to MCM for Force Protection and Counter-Terrorism. Recent progress in underwater robotics has been aimed at developing small, rapidly deployable Autonomous Underwater Vehicles (AUV) to achieve a large spatial sampling for both acoustic and non-acoustic measurements. The vehicles that are now commercially available, have great potential to work in conjunction with existing MCM assets and have several advantages: significantly faster search rate, reduced danger to divers, rapid deployability, and ability to carry out surveys in confined areas. The NATO Undersea Research Centre studies the performance of AUVs equipped with COTS sensors and working in conjunction with conventional assets (Mine Hunters and divers) to carry out MCM operations in ports and port approaches. To measure the effectiveness of this new technology in comparison to current practice, several experiments have been conducted in the ports of La Spezia (Italy), Strenraer (Scotland), Rotterdam (Netherlands) and Olpenitz (Germany). The paper summarizes the results and discusses the lessons learnt from the trials.
High-Dose Etoposide, Cyclophosphamide and Total Body Irradiation with Allogeneic Bone Marrow Transplantation for Resistant Acute Myeloid Leukemia: A Study by the North American Marrow Transplant Group (1996)

We evaluated the toxicity and efficacy of high-dose etoposide, cyclophosphamide and total body irradiation (TBI) followed by allogeneic bone marrow transplantation (BMT) for patients with resistant, acute myeloid leukemia (AML). Between 9/84 and 11/92 we treated 70 patients with etoposide (900-1800 mg/m2), cyclophosphamide (120-180 mg/kg) and TBI (1000-1200 cGy) followed by allogeneic BMT from histocompatible siblings. Forty patients were in untreated first relapse. Median time from diagnosis to transplant was 10 months. Toxicity was similar to that observed with cyclophosphamide/TBI with the median duration of neutropenia (ANC < 500/microliters) being 19 days (range 10-27) and the median duration of thrombocytopenia being 23 days (range 13-173). Twenty-three patients remain in continuous complete remission at a median of 56 months after transplant (range 36-132 months). Probabilities of disease-free survival, persistent/recurrent disease and transplant related mortality are .32, .47, and .37 respectively. Multivariate analysis indicated that grade > or = 2 acute graft-vs-host disease and transplant in untreated first relapse were associated with increased DFS due to reduced relapse risk. We conclude that high-dose etoposide with cyclophosphamide and TBI followed by allogeneic BMT is effective therapy for resistant AML, producing durable remission in approximately one-third of those treated. Disease persistence or recurrence was the major cause of treatment failure. Further improvement in DFS following allogeneic BMT for resistant AML might be achieved by using less intensive GVHD prophylaxis or through infusion of donor peripheral blood cells in patients who fail to develop significant acute GVHD.
Coping with derivation in a morphological component (1993)

In this paper a morphological component with a limited capability to automatically interpret (and generate) derived words is presented. The system combines an extended two-level morphology [Trost, 1991a; Trost, 1991b] with a feature-based word grammar building on a hierarchical lexicon. Polymorphemic stems not explicitly stored in the lexicon are given a compositional interpretation. That way the system allows to minimize redundancy in the lexicon because derived words that are transparent need note to be stored explicitly. Also, words formed ad-hoc can be recognized correctly. The system is implemented in CommonLisp and has been tested on examples from German derivation.

Degradable poly(amido amine)s as gene delivery carriers (2011)

The future of gene-based therapy needs to identify approaches to develop new carriers, depending on the properties of the biological membranes they face, and their physicochemical properties, in order to successfully deliver the genes to the target sites. With the emergence of a variety of non-viral vectors, such as biodegradable polymers, it may not take long before non-viral vectors are observed that are not just safe and tissue-specific, but even more efficient than viral vectors.
Parametric imaging using digital subtraction angiography (1986)

Digital subtraction angiography following an injection of iodinated contrast material can regularly produce good quality images. In addition to the conventional anatomical information, the timed sequence of digital images also contains useful temporal information which hitherto has been largely ignored. A simple method of image processing is described which utilises this timing information and presents it as a colour-coded set of functional images. Three parameters MAX, T-MAX and T-1/2 MAX are extracted from time-density curves, analogous to the time-activity curves of Nuclear Medicine, on a pixel-by-pixel basis. These parameters are used as a measure of overall organ perfusion, blood transit time between different vascular compartments, and as an indication of the initial delivery of contrast material to an organ. They have found use in the analysis of myocardial perfusion, before and after pharmacological intervention, and in the examination of the cerebral and renal circulations. The potential advantages of this technique derive from its superior spatial, temporal and contrast resolution.

New insights into the mechanisms of signal formation in RF‐spoiled gradient echo sequences (2005)

RF spoiling is a well established method to produce T(1)-weighted images with short repetition-time gradient-echo sequences, by eliminating coherent transverse magnetization with appropriate RF phase modulation. This paper presents 2 novel approaches to describe signal formation in such sequences. Both methods rely on the formulation of RF spoiling as a linear increase of the precession angle between RF pulses, which is an alternative to the commonly used quadratic pulse phase scheme. The first technique demonstrates that a steady state signal can be obtained by integrating over all precession angles within the voxel, in spite of the lack of a genuine steady-state for separate isochromats. This clear mathematical framework allows a straightforward incorporation of off-resonance effects and detector phase settings. Moreover, it naturally introduces the need for a large net gradient area per repetition interval. In the second step, a modified partition method including RF spoiling is developed to obtain explicit expressions for all signal components. This provides a physical interpretation of the deviations from ideal spoiling behavior in FLASH and echo-shifted sequences. The results of the partition method in the small flip angle regime are compared with numerical simulations based on a Fourier decomposition of magnetization states. Measurements performed with in vitro solutions were in good agreement with numerical simulations at short relaxation times (T(1)/TR = 32 and T(2)/TR = 4); larger deviations occurred at long relaxation times (T(1)/TR = 114 and T(2)/TR = 82).
The Gastric Lipase in Man (1946)

Summary. A reexamination has been carried out of the problems concerned with the gastric lipase in man, mainly with pure triglycerides as substrates. Both in vitro and in vivo experiments were undertaken. The optimum pH for gastric lipase towards tripropionin, tributyrin and tricaproin in systems without the addition of CaCl 2 is found to be between 5.5 and 5.8. With an increasing number of C‐atoms in the fatty acids there is an evident displacement of the optimum pH to the alkaline side, the optimum pH for tricaprin, trilaurin and tristearin being 7.2, 7.3 and 7.9 respectively. Addition of CaCl 2 to the enzyme‐substrate systems causes definite activation of the hydrolysis of trilaurin and tristearin at pH lower than 7, and the optimum pH is shifted 1.5 to 2 pH units to the acid side. The relative activities of gastric lipase towards different triglycerides have been computed. Tributyrin is split with the greatest initial velocity, whereas the relative activities towards the solid triglycerides are very small. Experiments on the stability of gastric lipase at 40° C at different pH values show that gastric lipase is a very stable enzyme in the acid medium. The lipolysis stated in our experiments in vivo is according to our opinion due to a specific gastric lipase and not to a regurgitated pancreatic lipase. Experiments in vivo with test meals containing pure triglycerides show that only the lower triglycerides are split to an appreciable extent during the experimental period of 25 min. Under similar experimental conditions there seems to be hardly any difference between the degrees of hydrolysis of fatty substances in the stomach by means of the gastric lipase in adults and in children. Under similar experimental conditions in children there is a tendency to a higher splitting in the stomach of cow‐butter fat than of woman's milk fat when these fats are given in test meals.
