Blood-Brain Barrier Permeability Changes after Experimental Subarachnoid Hemorrhage (1992)

Basic mechanisms underlying cerebrovascular permeability responses to subarachnoid hemorrhage (SAH) are still to be defined in detail. Previous investigations examining the occurrence of blood-brain barrier (BBB) breakdown after SAH in the experimental setting have yielded conflicting results. In a rat model of SAH, we assessed BBB changes by means of the quantitative [14C]-alpha-aminoisobutyric acid technique. Experiments were carried out on the second day post-SAH. In blood-injected rats [14C]-alpha-aminoisobutyric acid transport across the BBB increased significantly in cerebral cortices and cerebellar gray matter, averaging 1.3 to 1.5 times control values. The present data indicate that SAH induces well-defined changes in BBB function, possibly involved in the pathogenesis of post-SAH cerebral dysfunction in humans. Results reported here have also potential clinical implications for the management of aneurysm patients.
High-Quality-Factor Active Capacitors for Millimeter-Wave Applications (2012)

This paper presents single-ended and differential configurations of active capacitors that exhibit high-quality ( <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</i> ) factor at millimeter-wave frequencies. Both structures provide a small tunable negative resistance that can be exploited to compensate for the loss of other components, such as inductors in millimeter-wave integrated circuits. Unlike passive capacitors, which exhibit increasing capacitance with frequency (due to the inductive parasitic), the proposed active capacitors display relatively frequency-independent values. Fabricated in 0.13-μm IBM CMOS, tunable <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Q</i> values of more than 20 are obtained at 60 GHz. A 40-GHz bandpass filter is designed and fabricated using the single-ended active capacitor cells in a 0.13-μm IBM CMOS process exhibiting 0-dB insertion loss.
Getting the picture (2007)

This article is about looking: looking at images and the problematics of seeing and interpretation that this activity entails; and looking for images, in the sense of searching for the pictures that one would like to see. A significant development of the age of digital reproduction, of a technological environment that allows access to more visual images than ever before, is that these two ‘looks’ have become entangled. For the user of digital archives and databases, there has to be a way of finding and retrieving relevant images from a corpus of hundreds, even thousands, of images, which can then be seen and interpreted; while for the developer of these digital repositories, the interpretative process has always already begun: one has to analyse the images in order to determine how they can, or should, be searched. This article, then, is literally about ‘getting the picture’, of the new possibilities of searching for, across and within pictures that is opened up by recent technologies. However, it is also about the problems raised by this process. In particular, it explores the implications of textually describing, or ‘marking up’ images so that they can be searched.
DEBUGGING OPTIMIZED CODE WITHOUT BEING MISLED: CURRENCY DETERMINATION (1993)

This paper describes a mapping between statements and breakpoint locations that ameliorates this problem. The mapping enables debugger behavior on optimized code that approximates debugger behavior on unoptimized code sufficiently closely for the user to use traditional debugging strategies. Optimization can also cause the value of a variable to be noncurrent --- to differ from the value that would be predicted by a close reading of the source code. This paper presents a method of determining when this has occurred, and shows how a debugger can describe the relevant effects of optimization. The determination method is more general than previously published methods; it handles global optimization and many flow graph transformations, and it is not tightly coupled to optimizations performed by a particular compiler. Necessary compiler support is also described.

X-Ray Diffraction Study of Aqueous Montmorillonite Emulsions (1984)

Abstract An X-ray diffraction study of aqueous emulsions of a Na-montmorillonite shows that: (1) At low water content, the d-spacings of the montmorillonite increased stepwise with increasing water content; (2) At high water content, sharp (001) peaks due to regular stacking of montmorillonite layers were not detectable, but broad, halo patterns were observed in the low-angle scattering region; and (3) The addition of Ca 2+ or H + to the aqueous emulsions caused Ca-montmorillonite or H-montmorillonite crystals to form. A zig-zag column model of montmorillonite layers fits the observed data for aqueous emulsions of Na-montmorillonite.
Opposite Face Sensitivity of CeO<sub>2</sub> in Hydrogenation and Oxidation Catalysis (2014)

The determination of structure-performance relationships of ceria in heterogeneous reactions is enabled by the control of the crystal shape and morphology. Whereas the (100) surface, predominantly exposed in nanocubes, is optimal for CO oxidation, the (111) surface, prevalent in conventional polyhedral CeO2 particles, dominates in C2H2 hydrogenation. This result is attributed to the different oxygen vacancy chemistry on these facets. In contrast to oxidations, hydrogenations on CeO2 are favored over low-vacancy surfaces owing to the key role of oxygen on the stabilization of reactive intermediates. The catalytic behavior after ageing at high temperature confirms the inverse face sensitivity of the two reaction families.

Cell Cycle and Genetic Requirements of Two Pathways of Nonhomologous End-Joining Repair of Double-Strand Breaks in <i>Saccharomyces cerevisiae</i> (1996)

In Saccharomyces cerevisiae, an HO endonuclease-induced double-strand break can be repaired by at least two pathways of nonhomologous end joining (NHEJ) that closely resemble events in mammalian cells. In one pathway the chromosome ends are degraded to yield deletions with different sizes whose endpoints have 1 to 6 bp of homology. Alternatively, the 4-bp overhanging 3' ends of HO-cut DNA (5'-AACA-3') are not degraded but can be base paired in misalignment to produce +CA and +ACA insertions. When HO was expressed throughout the cell cycle, the efficiency of NHEJ repair was 30 times higher than when HO was expressed only in G1. The types of repair events were also very different when HO was expressed throughout the cell cycle; 78% of survivors had small insertions, while almost none had large deletions. When HO expression was confined to the G1 phase, only 21% were insertions and 38% had large deletions. These results suggest that there are distinct mechanisms of NHEJ repair producing either insertions or deletions and that these two pathways are differently affected by the time in the cell cycle when HO is expressed. The frequency of NHEJ is unaltered in strains from which RAD1, RAD2, RAD51, RAD52, RAD54, or RAD57 is deleted; however, deletions of RAD50, XRS2, or MRE11 reduced NHEJ by more than 70-fold when HO was not cell cycle regulated. Moreover, mutations in these three genes markedly reduced +CA insertions, while significantly increasing the proportion of both small (-ACA) and larger deletion events. In contrast, the rad5O mutation had little effect on the viability of G1-induced cells but significantly reduced the frequency of both +CA insertions and -ACA deletions in favor of larger deletions. Thus, RAD50 (and by extension XRS2 and MRE11) exerts a much more important role in the insertion-producing pathway of NHEJ repair found in S and/or G2 than in the less frequent deletion events that predominate when HO is expressed only in G1.
A provably correct design of a fault-tolerant clock synchronization circuit (2003)

A prototype fault-tolerant clock synchronization system is designed to a proven correct formal specification. The specification is derived from F.B. Schneider's (1987) general paradigm for Byzantine resilient clock synchronization. One addition to the formal theory is a mechanism for proven recovery from a bounded, number of transient faults. A description of a four-clock implementation which satisfies the requirements of the formal theory is presented. In addition, the design provides options for initialization which permit recovery from some correlated transient failures. Extra logic is included to provide experimental control of these options. Simulation results are presented Scenarios studied include achieving initial synchronization between clocks, resynchronization of a lost clock, and general behavior during upset or in the presence of a faulty clock. The simulation estimates of the times required from power-on to achievement of initial synchronization and to resynchronize a lost clock corroborate the initial analysis of the algorithms and meet the performance criteria and constraints of the theory.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Smart Wireless Sensor Network Powered by Random Ambient Vibrations (2006)

Over the past years, there has been a lot of efforts on the development of wireless sensor networks. However, the major constraint on broad application of wireless sensor network is still the battery lifetime on the wireless sensor nodes. In this paper, a complete power efficient sensor network system will be presented, and energy harvesting from ambient vibrations to further extend battery lifetime will also be detailed. The consideration on the power efficient design will take all aspects from hardware to network protocols. A tunable resonant frequency power harvesting device in cantilever beam form which will shift its resonant frequency to match that of the external vibrations adapting to the random ambient vibrations will also be presented to gain high energy harvesting efficiency from random ambient vibrations. With all the power saving and the power harvesting features implemented in the wireless sensor network design, years of battery lifetime on the sensor node could be expected. The experiment verification of the system and also scenario analysis on battery lifetime will also be presented in this paper.

Recurrent nonimmune hydrops fetalis: a rare presentation of sialic acid storage disease. (1999)

A case of recurrent hydrops fetalis, diagnosed on second trimester's ultrasonography, has led to the diagnosis of sialic acid storage disease. No classic etiology was found after the first accident. The recurrence in subsequent pregnancy raised the possibility of a storage disease that was confirmed by amniocentesis. The diagnosis of Salla's disease was based on high levels of free sialic acid in amniotic fluid and fetal cells culture and by specific histologic features on fetopathologic examination. Diagnosis of inherited diseases is important because it implies a high risk of recurrence which makes mandatory genetic counseling and prenatal care in subsequent pregnancies.
Fluid Stabilization during Isoelectric Focusing in Cylindrical and Annular Columns (1987)

Abstract The interest in fluid stabilization of focusing columns results from the attractive prospect of preparative isoelectric focusing as an alternative to chromatographic separations for downstream processing of proteins and pep-tides. In isoelectric focusing there is a variation of buffer composition, pH, conductivity, and temperature along the separation axis. The disturbing effects of the latter two parameters can be minimized using solid support media or gels. However, gravity-dependent convection and gravity-independent electroosmosis hamper focusing in free fluids in a complex way that prevents the scaling up of this process while maintaining the exquisite resolution of the analytical scale. The present study discusses methods for minimizing these disturbing effects in annular and cylindrical focusing columns of varying cross-sectional areas and internal geometries.
Fine tuning selection semantics in a structure editor based programming environment: some experimental results (1988)

Structure editing holds much promise for improving the quality of introductory programming education. However early structure editors have often been clumsy and counter intuitive to use. This study reports the results of a laboratory experiment in which the user interface of a structure editing environment was modified in several ways to make its semantics more closely resemble what students seem naturally to expect. Analysis suggests that it is possible to improve students' editing performance, without getting bogged down in unnecessary details of language and environmental semantics.

Spectral IP studies of Finnish ore prospects (1992)

Abstract Spectral-induced polarization (IP) field measurements, both in the frequency domain and in the time domain, were made at six early Proterozoic sulfide, oxide, and graphitic-gneiss deposits in Finland. Core samples were also measured. The textures of the mineralizations were studied from thin and polished sections.Deposits with large differences in texture, such as graphitic gneiss and coarse-grained disseminated sulfide, can be separated on the basis of their phase-spectra time constants. A good correlation was found between the observed grain size in thin sections and the grain size calculated from the apparent, field-survey phase spectra in the case of homogeneous, disseminated textures.The measured frequency-domain phase spectra, and phase spectra calculated from the time-domain Cole-Cole parameters are very similar in a comparable frequency band. For both techniques, the phase maximum lies beyond the lowest measured frequency. The possibilities to expand the frequency band to levels low enough to reach the phase maximum seem to be restricted. However, the results indicate that contrasts between spectra from different ore-texture types also appear at higher frequencies.
Generative Speech Coding with Predictive Variance Regularization (2021)

The recent emergence of machine-learning based generative models for speech suggests a significant reduction in bit rate for speech codecs is possible. However, the performance of generative models deteriorates significantly with the distortions present in real-world input signals. We argue that this deterioration is due to the sensitivity of the maximum likelihood criterion to outliers and the ineffectiveness of modeling a sum of independent signals with a single autoregressive model. We introduce predictive-variance regularization to reduce the sensitivity to outliers, resulting in a significant increase in performance. We show that noise reduction to remove unwanted signals can significantly increase performance. We provide extensive subjective performance evaluations that show that our system based on generative modeling provides state-of-the-art coding performance at 3 kb/s for real-world speech signals at reasonable computational complexity.
Three-step PCR mutagenesis for 'linker scanning' (1993)

'Linker scanning' has been used as an efficient method for systematically surveying a segment of DNA for functional elements by mutagenesis. A three-step PCR method was developed to simplify this process. In this method, a set of 'mutation primers' was made with 6 to 8 base substitutions in the center of the primers. In the first PCR reaction, these 'mutation primers' are paired with an 3' primer from the opposite end of the analyzed sequences to form a 'ladder' of fragments containing the base pair substitutions. These are used as templates in the second PCR with the 3' primer as the only primer to generate single stranded sequences, which are used as primers in the third PCR paired with an 5' primer to complete the mutagenesis. We have tested the method in a mutation screen of the steroid sulfatase promoter. Its application to general site specific mutagenesis is discussed.
ISDN primary rate access maintenance (2003)

A maintenance plan for integrated services digital network (ISDN) primary rate access (PRA) is described. The maintenance plan relies on an in-service performance monitoring approach for the digital transmission aspects of ISDN PRAs. The plan also includes testing to supplement in-service performance monitoring. The maintenance operations environment is first reviewed. Network element (NE), customer-premises-located network terminal (NT), and operations system (OS) capabilities are then identified to support in-service performance monitoring of digital transmission quality on ISDN PRAs. The strategy also uses out-of-service testing for trouble isolation and repair verification. Also discussed are the possible directions for extending the strategy after some experience is gained from initial primary access deployment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Formulation Studies of Effervescent Suppositories. Part II. Effects of Bases and Additives on Release of Carbon Dioxide from Effervescent Suppositories. (1993)

For the formulation of effervescent containing sodium bicarbonate and anhydrous sodium dihydrogen phosphate, the effects of bases and additives on the release profile of carbon dioxide, CO2, from the suppositories were studied by an in vitro release test using a gas burette. The suppository bases employed were Witepsol H-15, W-35 and E-85, and the additives were Aerosil 200 and soybean lecithin. The melting points and viscosities of the suppositories were also measured to interpret the CO2 release profiles. The rate and amount of CO2 released from suppositories prepared with bases having different melting points and hydroxyl values decreased with increasing melting point and decreasing hydroxyl value. The addition of Aerosil 200 to the suppository bases considerably reduced the rate and amount of CO2 released owing to the increasing viscosity of the melted bases, while the addition of soybean lecithin to those bases increased the rate and amount of CO2 released because of the improved wettability. Thus, the release profiles of CO2 from the effervescent suppositories were considerably influenced by the hydroxyl values related to the contents of mono- and di-glycerides, the melting points of the bases, Aerosil 200 and soybean lecithin. This suggests that the rate and amount of CO2 released from the suppositories can be freely controlled by the combination of these various factors.
