Toolkit Support for Integrating Physical and Digital Interactions (2009)

ABSTRACT There is great potential in enabling users to interact with digital information by integrating it with everyday physical objects. However, developing these interfaces requires programmers to acquire and abstract physical input. This is difficult, is time-consuming, and requires a high level of technical expertise in fields very different from user interface development—especially in the case of computer vision. Based on structured interviews with researchers, a literature review, and our own experience building physical interfaces, we created Papier-Mâché, a toolkit for integrating physical and digital interactions. Its library supports computer vision, electronic tags, and barcodes. Papier-Mâché introduces high-level abstractions for working with these input technologies that facilitate technology portability. We evaluated this toolkit through a laboratory study and longitudinal use in course and research projects, finding the input abstractions, technology portability, and monitoring facilities to be highly effective.
Perspectives on Using <i>Physcomitrella</i> Patens as an Alternative Production Platform for Thapsigargin and Other Terpenoid Drug Candidates (2009)

To overcome the potential future demand for terpenoids used as drugs, a new production platform is currently being established in our laboratory. The moss Physcomitrella has been chosen as the candidate organism for production of drug candidates based on terpenoids derived from plants, with a primary focus on the sesquiterpene lactone, thapsigargin. This drug candidate and other candidates/drugs with sesquiterpene skeleton are difficult to obtain by chemical synthesis due to their large number of chiral centers. Furthermore, they are not available in sufficient amounts from their original plant. The requirement for a new production system to meet the potential market demand for these compounds is not only obvious, but also essential if sufficient quantities of the drug candidates are to be available for the potential therapeutic use.
Effects of Congestive Heart Failure on Ca <sup>2+</sup> Handling in Skeletal Muscle During Fatigue (2006)

Skeletal muscle weakness and decreased exercise capacity are major symptoms reported by patients with congestive heart failure (CHF). Intriguingly, these skeletal muscle symptoms do not correlate with the decreased heart function. This suggests that CHF leads to maladaptive changes in skeletal muscles, and as reported most markedly in slow-twitch muscles. We used rats at 6 weeks after infarction to measure expression of key proteins involved in SR Ca(2+) release and uptake in slow-twitch soleus muscles. We also measured force and myoplasmic free [Ca(2+)] ([Ca(2+)](i)) in intact single fibers of soleus muscles. CHF rats showed clear signs of severe cardiac dysfunction with marked increases in heart weight and left ventricular end-diastolic pressure compared with sham operated rats (Sham). There were small, but significant, changes in the content of proteins involved in cellular Ca(2+) handling in CHF muscles: slight increases in SR Ca(2+) release channels (ie, the ryanodine receptors) and in SR Ca(2+)-ATPase. Tetanic force and [Ca(2+)](i) were not significantly different between CHF and Sham soleus fibers under resting conditions. However, during the stimulation period there was a decrease in tetanic force without changes in [Ca(2+)](i) in CHF fibers that was not observed in Sham fibers. The fatigue-induced changes recovered rapidly. We conclude that CHF soleus fibers fatigue more rapidly than Sham fibers because of a reversible fatigue-induced decrease in myofibrillar function.

Induction of Asymmetry by Amino Acids (1982)

Abstract Since the stereoisomers of molecules with one or more asymmetric centers often exhibit different biological activities ( e.g. thalidomide, pheromones), stereoselective synthesis as a method of preparative chemistry is rapidly attaining importance. Of the numerous drugs prepared by total synthesis that contain at least one asymmetric center, only about 20% have so far been used in sterically pure form. Amino acids constitute the greatest “chiral pool” of compounds whose enantiomers can be obtained commercially in large amounts; they are gradually being used more and more frequently as auxiliary agents or educts in asymmetric syntheses.
Some Studies in Machine Learning Using the Game of Checkers. II—Recent Progress (1967)

A new signature table technique is described together with an improved book learning procedure which is thought to be much superior to the linear polynomial method described earlier. Full use is made of the so called “alpha-beta” pruning and several forms of forward pruning to restrict the spread of the move tree and to permit the program to look ahead to a much greater depth than it otherwise could do. While still unable to outplay checker masters, the program's playing ability has been greatly improved.
Printed document authentication using two level or code (2016)

The availability of high quality copy machines provides a large amount of printed document counterfeits. Numerous authentication techniques based on security printing, graphical codes, hashing or local hashing have been suggested earlier. In this paper, we propose a novel printed document authentication system based on sensitivity of a new two level QR (2LQR) code to copying process. This 2LQR code contains specific textured patterns, which are sensitive to printing and copying processes. Therefore, it can be used to detect unauthorized document duplication. Experimental results show the efficiency of this 2LQR code for copy detection.

Facile and Selective Alkylation of 3,3,3-Trifluoropropene Oxide (TFPO) with Organoaluminum Reagents via Pentacoordinate Trialkylaluminum Complexes (1998)

Abstract A new organoaluminum-promoted selective alkylation of 3,3,3-trifluoropropene oxide (TFPO) with several nucleophiles has been developed which involves the chelation-activated addition to fluoro epoxides via pentacoordinate trialkylaluminum complexes.
Synthesis and redox behaviour of highly conjugated bis(benzo-1,3-dithiole) and bis(benzothiazole) systems containing aromatic linking groups: model systems for organic metals (1990)

The synthesis and electrochemical redox properties of a series of symmetrical, highly conjugated bis(benzo-1,3-dithiole) and bis(benzothiazole) derivatives (8)–(24) are described. The heterocyclic end-groups are linked by a conjugated framework that incorporates the following groups: (a) phenyl, (b) naphthyl, (c) thienyl, (d) biphenyl, (e) anthracenyl, and (f) benzanthracenyl. Compounds (13) and (16)–(19) display two, single-electron redox waves in the cyclic voltammogram, while compounds (8)–(12), (14), (15), (20), (21), (23), and (24) display a single, two-electron redox wave. The redox potentials of these molecules can be correlated with the increased stability of the redox state of the system in which the central, bridging ring is aromatic.
Dual-scale topology optoelectronic processor (1991)

The dual-scale topology optoelectronic processor (D-STOP) is a parallel optoelectronic architecture for matrix algebraic processing. The architecture can be used for matrix-vector multiplication and two types of vector outer product. The computations are performed electronically, which allows multiplication and summation concepts in linear algebra to be generalized to various nonlinear or symbolic operations. This generalization permits the application of D-STOP to many computational problems. The architecture uses a minimum number of optical transmitters, which thereby reduces fabrication requirements while maintaining area-efficient electronics. The necessary optical interconnections are space invariant, minimizing space-bandwidth requirements.

Vehicle Localization in Outdoor Mountainous Forested Paths and Extension of Two-Dimensional Road Centerline Maps to Three-Dimensional Maps (2010)

This paper presents an approach for vehicle three-dimensional (3-D) localization in outdoor woodland environments where a previously available two-dimensional road centerline map is used in combination with a loosely coupled multi-sensor system to estimate the vehicle position in mountainous forested paths. The localization system is composed of a wheel encoder, an inertial measurement unit, a DGPS, a laser sensor and a barometer. An extended Kalman filter is used for sensor data fusion and pose estimation. When available, DGPS is used for 3-D dead reckoning accumulated error correction. During DGPS blackouts, the laser sensor is used for road extraction and measurement of the displacement of the vehicle to the road centerline, then the position is corrected towards the map. Moreover, the barometer that measures the height difference towards a reference is used to correct the estimated height in absence of DGPS 3-D data. The estimated height is added to the available road map to obtain a 3-D road centerline map that includes the road width measured with the laser sensor. Experimental results in large-scale real mountainous woodland environments show the robustness and simplicity of the proposed approach for vehicle localization and 3-D map extension.

Combinatorial signals from the neural tube, floor plate and notochord induce myogenic bHLH gene expression in the somite (1995)

The neural tube, floor plate and notochord are axial tissues in the vertebrate embryo which have been demonstrated to play a role in somite morphogenesis. Using in vitro coculture of tissue explants, we have monitored inductive interactions of these axial tissues with the adjacent somitic mesoderm in chick embryos. We have found that signals from the neural tube and floor plate/notochord are necessary for expression of the myogenic bHLH regulators MyoD, Myf5 and myogenin in the somite. Eventually somitic expression of the myogenic bHLH genes is maintained in the absence of the axial tissues. In organ culture, at early developmental stages (HH 11-), induction of myogenesis in the three most recently formed somites can be mediated by the neural tube together with the floor plate/notochord, while in more rostral somites (stages IV-IX) the neural tube without the floor plate/notochord is sufficient. By recombining somites and neural tubes from different axial levels of the embryo, we have found that a second signal is necessary to promote competence of the somite to respond to inducing signals from the neural tube. Thus, we propose that at least two signals from axial tissues work in combination to induce myogenic bHLH gene expression; one signal derives from the floor plate/notochord and the other signal derives from regions of the neural tube other than the floor plate.

Reduced c-Myc signaling triggers telomere-independent senescence by regulating Bmi-1 and p16 <sup>INK4a</sup> (2006)

Increased mitogenic signaling by positive effectors such as Ras or Myc can trigger senescence in normal cells, a response believed to function as a tumor-suppressive mechanism. We report here the existence of a checkpoint that monitors hypoproliferative signaling imbalances. Normal human fibroblasts with one copy of the c-myc gene inactivated by targeted homologous recombination switched with an increased frequency to a telomere-independent senescent state mediated by the cyclin-dependent kinase inhibitor p16(INK4a). p16(INK4a) expression was regulated by the Polycomb group repressor Bmi-1, which we show is a direct transcriptional target of c-Myc. The Myc-Bmi circuit provides a mechanism for the conversion of environmental inputs that converge on c-Myc into discrete cell-fate decisions coupled to cell-cycle recruitment. A mechanism for limiting the proliferation of damaged or otherwise physiologically compromised cells would be expected to have important consequences on the generation of replicatively senescent cells during organismal aging.
Inductive bandwidth enhancement of sub-μm InAlAs-InGaAs MSM photodetectors (1995)

We report on the inductive bandwidth enhancement of InGaAs metal-semiconductor-metal photodetectors with finger spacings in the sub-μm range. For optimized circuit design, the calculated frequency response predicts an improvement of the 3-dB bandwidth by more than a factor of two. A first implementation using InAlAs-InGaAs:Fe MSM detectors with 0.7-μm finger spacing results in a 28-GHz bandwidth demonstrating the feasibility of the approach.

Query Processing in Encrypted Cloud Databases (2013)

With the increasing popularity of cloud computing, a new model known as Database-asa-service (DAAS) model has emerged in recent years. In this model a service provider provides the database as a service to its clients over internet. One of the biggest problem in DAAS is “How to execute queries efficiently at the cloud resident server while maintaining data security”. In this work we present PhantomDB, which is a new framework for solving this problem. PhantomDB maintains data security by encrypting the data before storing it on the server. Each data item is encrypted under multiple encryption schemes. The Encryption schemes used by PhantomDB are carefully chosen to allow efficient query processing at the server. PhantomDB introduces the concept of Arithmetic Engine and Round Communication, which allow it to support all the standard SQL constructs with the exception of similarity operators. PhantomDB is able to support 16 out of 22 TPCH Benchmark queries. We also present a new hybrid storage model which takes unique features of PhantomDB into consideration while deciding the layout of relational data on disk. It helps in improving the performance of PhantomDB as compared to other current storage models.
The use of encryption to ensure the integrity of reusable software components (2002)

Several efforts are currently underway to foster a marketplace for reusable software components based upon interoperating electronic libraries containing managed collections of components. In such a marketplace, it is necessary for potential users to be able to verify the origin of candidate components and to assure that they have not been modified by third parties. This paper proposes a method for providing the assurance through the application of modern encryption techniques.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effect of 9-(1,3-dihydroxy-2-propoxymethyl)guanine on human cytomegalovirus replication in vitro (1983)

We studied the effect of a novel purine acyclic nucleoside, 9-(1,3-dihydroxy-2-propoxymethyl)guanine (DHPG), on human cytomegalovirus (HCMV) replication. The susceptibility of HCMV to this drug was monitored in cell culture by plaque reduction assay. HCMV replication of various strains was inhibited to the extent of 50% by 1 to 5 microM DHPG. DHPG was highly specific in its anti-HCMV activity, since at concentrations as high as 100 microM it did not exert any detectable inhibitory effect on uninfected cell macromolecular synthesis and cell growth. At concentrations of 2 to 4 microM, the drug inhibited the synthesis of six virus-specific polypeptides with molecular weights of 200,000 (VP200), 150,000 (VP150), 67,000 (VP67), 54,000 (VP54), 32,000 (VP32), and 27,000 (VP27) up to 96 h after infection. HCMV DNA synthesis was also considerably suppressed at concentrations of 2 to 4 microM DHPG. Upon removal of the inhibitor, however, viral DNA synthesis resumed and infectious virus reappeared, indicating that this inhibition was a virostatic reversible-type inhibition.
