Object technology (2nd ed.): a manager's guide (1997)

The first edition of Object Technology: A Manager's Guide is widely viewed as the classic introduction to this powerful computing concept. Object technology offers increased agility, significant time-to-market reduction, and the opportunity to exploit the potential of the World Wide Web by deploying globally distributed business systems. At a time when many of the world's largest companies are making the transition to object technology, David Taylor has updated his book to address the important issues facing the growth of object technology and to provide a glimpse into the future of this evolving paradigm. In updating this seminal work, David Taylor has retained the signature conciseness and,clarity of discussion that made the first edition a best-seller.Object Technology: A Manager's Guide, Second Edition, covers the key terms, emerging concepts, and useful applications of objects. Managers, salespeople, engineers, software developers-anyone interested in understanding or implementing object technology-will find this a lucid introduction to the topic.Highlights of this new edition include: An explanation of how to use objects to create evolutionarysoftware that rapidly adapts to changing business conditions,eliminating the need for most new application development. An introduction to Java, and an explanation of how its useof message interfaces enables a new generation of portable, mix-and-match, Internet-enabled business objects. An update on the state of object databases and extended relationaldatabases, with guidelines for combining the two for optimal informationstorage. An introduction to the new generation of object engines andhow they combine storage and execution capabilities for maximumsoftware integration. 0201309947B09102001
Interactions of Phenolic Acids, Metallic Ions and Chelating Agents on Auxin-Induced Growth (1966)

By growth experiments in indoleacetic acid-1-(14)C (IAA), and determination of the (14)CO(2) evolved, it has been shown directly that polyphenols synergize IAA-induced growth by counteracting IAA decarboxylation. Sinapic and ferulic acids act like polyphenols. Endogenous polyphenols doubtless exert the same influence in intact plants. Monophenols stimulate the decarboxylation of IAA under conditions where they depress growth. When Mn(++) is present as well, this effect is enhanced. All these growth effects are paralleled by effects on the isolated IAA oxidizing enzyme of Avena.EDTA acts like the polyphenols in depressing the decarboxylation of IAA, and not synergizing with the growth induced by naphthalene-acetic acid (NAA) and 2,4-D. However, since EDTA synergizes with IAA for growth even at optimal IAA concentrations, its growth promotion probably involves an additional effect.DIECA inhibits powerfully the destruction of IAA, but without causing much growth promotion, apparently because its decomposition products inhibit respiration.Mn(++) aloné stimulates the decarboxylation of IAA, i.e. this ion promotes the IAA oxidase in vivo as it does in vitro. Nevertheless, it does not inhibit elongation, but at relatively high concentrations even stimulates it, both at low and high IAA levels. Since Mn(++) also promotes the growth induced by NAA and 2,4-D, its growth action cannot rest primarily on modifying the metabolism of the auxins.Cobalt somewhat decreases the decarboxylation of IAA, but this cannot explain its growth promotion, since Co(++), like Mn(++), stimulates elongation even at optimal IAA concentrations, and acts with NAA just as well as with IAA. Ferrous ion, on the other hand, acts like the polyphenols.Floating pea stem sections exude enough organic matter to support bacteria which after 7 hours cause considerable decarboxylation of IAA. Avena coleoptile sections have a comparable though smaller effect after 12 hours.The present experiments, with those of others, point to a major role for polyphenolase in controlling hormone balance, since the introduction into a phenolic molecule of a second, adjacent hydroxyl group changes the action from auxin-destroying to auxin-preserving. Thus the phenol oxidizing enzymes must act as general growth controllers.

Allicat Magnetoresistive Head Design And Performance (2005)

The general design features of the magnetoresistive (MR) merged head are described and compared to the earlier MR piggy-back head called Corsair. Examples of static, magnetic and error rate testing are given. Dual track profiles show the read-narrow feature of the MR head. Stability of the signal with write disturbance shows the effectiveness of the hard-bias longitudinal biasing. Error rate vs. off-track position indicates the robustness of the file design. >
The state problem for test generation in Simulink (2006)

Search based test-data generation has proved successful for code-level testing. In this paper we investigate the application of such approaches at the higher levels of abstraction offered by Matlab-Simulink models. The presence of persistent state has been shown to be problematic at the code level and such difficulties remain when Matlab-Simulink models are to be tested. In such cases, sequences of inputs that can put the model under test into particular states are needed to enable the underlying test goals to be achieved. Simple search guidance appears to be insufficient and results in a 'flat' cost function landscape. To address this problem, we introduce a technique called tracing and deducing, which helps provide better guidance to the search, allowing our developed tools to home in on the targeted test-data.
Static Scheduling of Synchronous Data Flow onto Multiprocessors for Embedded DSP Systems (2011)

A method of scheduling onto multiprocessors for embedded DSP system applications is proposed. This method basing on SDF (Synchronous Data Flow) performs all of the scheduling at compile time by methods of periodic schedules. And it uses a Hierarchical Priority Scheduling algorithm, which first schedules the module of highest priority, to solve the problem, static scheduling of SDF onto Multiprocessors. Compared to other algorithms, it has better Time and Space Complexity because the conversion from SDF to APG (Acyclic Precedence Graphs) is unnecessary. Experimental results prove the validity of the proposed method.
A Low Power Bioimpedance Module for Wearable Systems (2014)

A low power novel architecture for the measurement of module and phase of bioimpedance (electrical impedance of body or of a part of it) is suggested. It enables to reach good performances with reduced consumption. The circuit has been prototyped and characterized. First tests for breathing rate monitoring demonstrated good functionality of the circuit.
Spatially-Adaptive Reconstruction in Computed Tomography Using Neural Networks (2015)

We propose a supervised machine learning approach for boosting existing signal and image recovery methods and demonstrate its efficacy on example of image reconstruction in computed tomography. Our technique is based on a local nonlinear fusion of several image estimates, all obtained by applying a chosen reconstruction algorithm with different values of its control parameters. Usually such output images have different bias/variance trade-off. The fusion of the images is performed by feed-forward neural network trained on a set of known examples. Numerical experiments show an improvement in reconstruction quality relatively to existing direct and iterative reconstruction methods.
An Inexpensive, Nondisruptive Method of in Situ Dart Tagging for Visual Recognition of Fish Underwater (1995)

We describe two devices for the underwater application of external dart and anchor tags to fish. The general method appears useful for applying individual-specific marks to many relatively large-bodied, approachable species. We observed high tag retention rates, low incidence of fish injury, and minimal behavioral disruption when applying tags. In situ tagging eliminates the need to capture, handle, and anesthetize individuals and it is particularly valuable for behavioral studies, where temporary removal of individuals may affect their social status.
The reaction between dicumyl peroxide and butyl rubbers (1964)

Abstract The reaction between dicumyl peroxide and butyl rubbers has been followed by means of molecular weight measurements. In all cases except that of the rubber with highest unsaturation the molecular weight falls, and the scission efficiency of the peroxide is found to depend quite markedly upon the unsaturation. For the rubber of highest unsaturation a small overall crosslinking reaction was observed. The results are interpreted as showing that cumyloxy radicals react with isoprene units in the chain about 300 times as fast as with isobutylene units. The molecular weight depen dance upon time during the reaction has been investigated but has not been satisfactorily explained.
Enhanced error vector magnitude (EVM) measurements for testing WLAN transceivers (2006)

As wireless LAN devices become more prevalent in the consumer electronics market, there is an ever increasing pressure to reduce their overall cost. The test cost of such devices is an appreciable percentage of the overall cost, which typically results from the high number of specifications, the high number of distinct test set-ups and equipment pieces that need to be used, and the high cost of each test set-up. In this paper, we investigate the versatility of EVM measurements to test the variable-envelope WLAN (Wireless Local Area Networks) receiver and transmitter characteristics. The goal is to optimize EVM test parameters (input data and test limits) and to reduce the number of specification measurements that require high test times and/or expensive test equipment. Our analysis shows that enhanced EVM measurements(optimized data sequence and limits, use of RMS, scale, and phase error vector values) in conjunction with a set of simple path measurements (input-output impedances) can provide the desired fault coverage while eliminating lengthy spectrum mask and noise figure tests
19‐1: A Novel Electrowetting‐based Display for Future Smart Window Application (2011)

Abstract Smart window is an emerging application for display industry. It can control the sunlight penetration and display information. In this paper, we had made 6‐inch color smart window prototype by electrowetting‐based technique. The ink jet process is adopted to dose various colored oil into sub‐pixel to achieve color device. Without color filter, the transmittance of the device can be improved. Further, to evaluate the practicability of using the smart window device in the night, we had added luminescence substances into the colored oils and designed the cladding structure to achieve a luminous smart window.
Hard-less dead-time compensator for PWM voltage inverters (2002)

In this paper, a hard-less control method based on a low computation algorithm to minimise the effect of nonideal behaviour of inverters is presented. Some experimental results are shown to demonstrate the validity of the proposed method. The method is based on a space vector pulse-width modulation strategy, and consists in making equal the real and the calculated stator flux, neglecting the stator resistance. Unlike classical methods, that minimise the effect of the dead time, this approach does not require any extra hardware for implementation, because it can be accomplished without any extra sensors, and furthermore the compensation algorithm will not add any computation load to the inverter's controller. This algorithm simply minimises the difference between two simple adders containing the discrete times calculated and those actually sent to the inverter.
Gap Junctions in the Control of Vascular Function (2008)

Direct intercellular communication via gap junctions is critical in the control and coordination of vascular function. In the cardiovascular system, gap junctions are made up of one or more of four connexin proteins: Cx37, Cx40, Cx43, and Cx45. The expression of more than one gap-junction protein in the vasculature is not redundant. Rather, vascular connexins work in concert, first during the development of the cardiovascular system, and then in integrating smooth muscle and endothelial cell function, and in coordinating cell function along the length of the vessel wall. In addition, connexin-based channels have emerged as an important signaling pathway in the astrocyte-mediated neurovascular coupling. Direct electrical communication between endothelial cells and vascular smooth muscle cells via gap junctions is thought to play a relevant role in the control of vasomotor tone, providing the signaling pathway known as endothelium-derived hyperpolarizing factor (EDHF). Consistent with the importance of gap junctions in the regulation of vasomotor tone and arterial blood pressure, the expression of connexins is altered in diseases associated with vascular complications. In this review, we discuss the participation of connexin-based channels in the control of vascular function in physiologic and pathologic conditions, with a special emphasis on hypertension and diabetes.
Cell-free protein synthesis in hydrogel materials (2020)

We report a method for embedding cell-free protein synthesis reactions in macro-scale hydrogel materials without a free liquid phase. This paper focuses on methods of preparation for a variety of hydrogels and an investigation of the impact that the hydrogel material has on cell-free protein synthesis.
Algebraic point set surfaces (2007)

In this paper we present a new Point Set Surface (PSS) definition based on moving least squares (MLS) fitting of algebraic spheres. Our surface representation can be expressed by either a projection procedure or in implicit form. The central advantages of our approach compared to existing planar MLS include significantly improved stability of the projection under low sampling rates and in the presence of high curvature. The method can approximate or interpolate the input point set and naturally handles planar point clouds. In addition, our approach provides a reliable estimate of the mean curvature of the surface at no additional cost and allows for the robust handling of sharp features and boundaries. It processes a simple point set as input, but can also take significant advantage of surface normals to improve robustness, quality and performance. We also present an novel normal estimation procedure which exploits the properties of the spherical fit for both direction estimation and orientation propagation. Very efficient computational procedures enable us to compute the algebraic sphere fitting with up to 40 million points per second on latest generation GPUs.
Lasing mechanism of InGaN/GaN/AlGaN multiquantum well laser diode (1998)

We investigated the lasing mechanism of an InGaN/GaN/AlGaN multiquantum well (MQW) laser diode on SiC grown by low-pressure metalorganic vapor phase epitaxy. Surface emission and edge emission are compared by optical pumping on the laser chip for which electrical pumping was made. Excitation power dependence of photoluminescence (PL) and PL mapping are also taken on the same chip. From the results, we demonstrate that lasing phenomena in our laser are dominated by free carriers and that the observed various stimulated emission lines are caused by the inhomogeneity of the InGaN MQW.
Serum leptin and cholesterol levels in schizophrenic patients with and without suicide attempts (2003)

The results indicated that medication-free schizophrenic patients have statistically significant lower serum cholesterol and leptin levels compared with controls and the difference is obvious in suicide attempters compared with non-suicide attempters and in violent attempters than non-violent attempters.
Color conversion for a multi‐primary display using linear interpolation on equi‐luminance plane method (LIQUID) (2003)

Abstract— A color‐conversion method, which converts an XYZ tristimulus value to a set of display signals for a multi‐primary display, has been developed. It is necessary for a display‐device driver in a color‐management system to select an optimal set of display signals that presents a given colorimetric value on a display screen. A multi‐primary display, which has more than four primaries, has more than two sets of display signals that generate the same colorimetric value theoretically. A display‐device driver, therefore, has to be designed according to a certain rule in order to choose a unique set of display signals for one colorimetric value only. To meet the requirement, a linear interpolation method, which uses three points on an equi‐luminance plane in XYZ tristimulus value space, has been developed. The developed method assigns three points on an equi‐luminance plane in XYZ tristimulus value space to ensure smoothness of a continuous gradation of display signals. The colorimetric accuracy of the developed method was evaluated with a six‐primary DLP™ projector. Colorimetric error in CIELAB space between the targets and reproductions is about 0.8 on average and 2.9 at maximum.
A comparison of two network-based file servers (1982)

This paper compares two working network-based file servers, the Xerox Distributed File System (XDFS) implemented at the Xerox Palo Alto Research Center, and the Cambridge File Server (CFS) implemented at the Cambridge University Computer Laboratory. Both servers support concurrent random access to files using atomic transactions, both are connected to local area networks, and both have been in service long enough to enable us to draw lessons from them for future file servers. We compare the servers in terms of design goals, implementation issues, performance, and their relative successes and failures, and discuss what we would do differently next time.
Synthesis and Evaluation of a Triplex-Forming Oligonucleotide−Pyrrolobenzodiazepine Conjugate (2004)

In most cases, unmodified oligonucleotides designed as antigene molecules are incapable of binding to DNA with sufficient stability to prevent gene expression. To stabilize binding to a polypurine tract in the HER-2/neu promoter, a triplex forming oligonucleotide (TFO) was conjugated to a pyrrolo[1,4]benzodiazepine (PBD), desmethyltomaymycin, and site-specific DNA binding was evaluated. An activated ester of the PBD moiety was conjugated by an acylation reaction to a free primary amine on a 50-atom aliphatic linker at the 5' end of the TFO. This long aliphatic linker was designed to provide a bridge from the major groove binding site of the TFO to the minor groove binding site of the PBD. Triplex formation by the resulting TFO-PBD conjugate occurred more slowly and with a nearly 30-fold lower affinity compared to an unconjugated TFO. PBD binding to the triplex target was demonstrated by protection from restriction enzyme digestion, and covalent binding to the exocyclic amino group of guanine was inferred by substituting specific guanines with inosines. Although the binding of the TFO was less efficient, this report demonstrates that in principle, TFOs can be used to direct the binding of a PBD to specific location. Further optimization of TFO-PBD conjugate design, likely involving optimization of the linker and perhaps placing a PBD at both ends of the TFO, will be needed to make gene modification robust.

The Automatic Timing of the Ostwald Viscometer by Means of a Photoelectric Cell (1933)

A new method for the automatic measurement of the time of flow of a liquid in a viscometer of the Ostwald type by means of a photoelectric cell is described. The elimination of the psychological errors inherent in the older technique permits greater precision. Other sources of error in the use of the Ostwald viscometer are analyzed and the precautions necessary for precision viscometry are discussed.
Membrane Filter Technique for Enumeration of <i>Pseudomonas aeruginosa</i> (1972)

A membrane filter procedure for the quantitation of Pseudomonas aeruginosa (mPA procedure) has been developed. Through the use of inhibitors and an elevated incubation temperature, the level of background microbial flora was decreased approximately 10,000-fold. Using P. aeruginosa cells suspended in sea water and held for 24 hr, between 70 and 100% of the “viable” cells could be recovered by the mPA procedure. Assay variability was found to be insignificant. The recoveries of P. aeruginosa from surface (fresh and salt) waters, potable waters, and sewage by the mPA procedure exceeded those obtainable by current methods. Subsequent to its development and evaluation, the mPA procedure was used at three other laboratories for the enumeration of P. aeruginosa in potable and recreational waters and in sewage samples. It was found amenable to routine use, and confirmation of typical colonies approached 100%.
