ENDOGENOUS DIGITALIS-LIKE NATRIURETIC FACTORS (1987)

There is increasing evidence for endogenous, circulating compounds that interact with the digitalis receptor of [Na,K]ATPase and with antidigoxin antisera. Circulating levels of these digitalis-like compounds increase in response to fluid or salt loading and appear to play a role in diseases characterized by fluid and salt retention, e.g. renal failure, liver disease, acromegaly, experimental and human hypertension, and preeclampsia. Because of assay nonspecificity, many diverse substances are being measured. Of the few compounds currently identified as having "digitalis-like" activity, none appears to be the natural ligand of the digitalis receptor and none appears linked with hypertension. Nevertheless, research still suggests that digitalis-like factors may have a central role in essential hypertension and related disorders.
Mesothelial cell-mediated gene therapy: feasibility of an ex vivo strategy. (1995)

We have developed a model system in the rat to test the feasibility of recombinant protein expression by genetically modified peritoneal mesothelial cells following autologous peritoneal implantation. Rat primary peritoneal mesothelial cells, isolated from parietal peritoneum by enzymatic digestion, were stably transduced (using a Moloney murine leukemia virus (MoMLV)-derived retroviral vector, BAG, expressing the Escherichia coli lacZ gene) to mark the cells with a reporter protein (beta-galactosidase, beta-gal). Such transduced mesothelial cells, tagged with DiO, a fluorescent lipophilic dye used for long-term tracing of transplanted cells, were then reseeded on the denuded peritoneal surface of syngeneic recipients. DiO-labeled, BAG-transduced mesothelial cells were observed to repopulate the denuded areas and remain attached there for > 90 days. Moreover, these genetically modified mesothelial cells continued to express the reporter gene product in vivo (ie beta-gal activity was present for at least 1 month). Our results demonstrate the feasibility of ex vivo gene therapy using peritoneal mesothelial cells.
Toward automated exploration of interactive systems (2002)

The ease with which a user interface can be navigated strongly contributes to its usability. In this paper we describe preliminary results of a project aimed at making the evaluation of user interfaces from this perspective more routine. We have designed a system to carry out an autonomous, exploratory navigation through the graphical user interface of interactive, off-the-shelf software applications. The system is not a robust tool, but rather a proof of concept that can exhibit interesting behaviors. The traversal process generates a representation of the connectivity of the user interface, as well as navigational paths to specific commands. The reasoning component of the system is based on the ACT-R architecture, while the perceptual and motor components of the system are built on top of the SegMan perception/action substrate. We present the design of the system and its use in exploring a simple user interface.
StreamCache: Popularity-based caching for adaptive streaming over information-centric networks (2016)

The growing demand for video streaming is straining the current Internet, and mandating a novel approach to future Internet paradigms. The advent of Information-Centric Networks (ICN) promises a novel architecture for addressing this exponential growth in data traffic, with ubiquitous caching to facilitate video delivery. In this paper, we present a novel in-network video caching policy in ICN, named StreamCache, catering to variable video contents with different sizes and bit rates. Our objective is improving the average throughput of users which consequently enhances the Quality of Experience (QoE), under the heterogeneity of users' devices and network conditions. StreamCache is a popularity-based policy, which operates distributively at routers, designed for the online processing in order to narrow the gap between the offline theoretical optimal solution and the real-world application. StreamCache operates in rounds, making caching decisions based on video request statistics and minimal cache coordination. We show that, StreamCache achieves near-optimal performance compared with the offline benchmark scheme, DASCache and outperforms current state-of-the-art protocols, such as ProbCache by presenting an elaborate evaluation carried out on ndnSIM, over NS-3.
Contra os dogmáticos: uma opinião cética sobre as bibliotecas (1974)

Medo e odio da palavra, e, por extensao, dos livros e das bibliotecas, sao paixoes das quais os filosofos, professores e bibliotecarios nao estao totalmente isentos. Mc Luhan nada mais e do que um exemplo recente do homem culto que despreza os livros. O proprio Platao era abertamente hostil a liberdade intelectual. Os filosofos nao sao, necessariamente, os melhores aliados dos bibliotecarios, e os filosofos sao, provavelmente, seus piores inimigos. O filosofo espanhol Jose Ortega y Gasset, em seu famoso discurso A Missao do Bibliotecario, defende para o bibliotecario a funcao de policia do livro, porem a missao do bibliotecario consiste, fundamentalmente, em criar bibliotecas. O bibliotecario precisa da formula cetica - ´a suspensao de julgamento´ - a fim de se orientar em sua missao profissional. Um universo repleto de problemas exige bibliotecas repletas de problemas que contenham muitos livros que talvez sejam ofensivos. A filosofia do ceticismo pode justificar a posicao do bibliotecario quando alguem se sentir ofendido.

Work Function Engineering With Linearly Graded Binary Metal Alloy Gate Electrode for Short-Channel SOI MOSFET (2011)

Over the last few decades, silicon-on-insulator (SOI) technology has been identified as one possible solution for enhancing the performance of CMOS because of its numerous advantages over conventional bulk CMOS technology. One of the primary drawbacks of short-channel SOI MOSFET is the degradation of device threshold voltage with decreasing channel length. Drain-induced barrier-lowering (DIBL) effect, generated from high drain bias, is the main cause behind this length-dependent nature of threshold voltage. This “instability” in threshold voltage is responsible for making SOI device design very challenging. The instability that is known as the threshold voltage rolloff restricts further scaling of SOI devices. In this paper, an idea of work function engineering with continuous horizontal mole fraction variation in a binary alloy gate has been proposed and implemented theoretically. Analytical model-based simulation verified that performance of proposed SOI MOSFET is improved as it has higher immunity to DIBL effect.

An efficient single receiver high resolution DOA estimation algorithm for modulated signals (2015)

Direction finding techniques can be applied to a number of military and civilian systems, such as radar, sonar, and radio communications. It aims at finding the Direction of Arrival of an electromagnetic source for positioning purposes. Direction finding systems can be primarily classified as multiple or single channel. The single-channel solution, investigated herein, is based on a switched antenna associated to a special Phase Locked Loop (PLL) receiver architecture that allows tracking the phase of each antenna. The PLL output is processed by a signal processing block that removes the ambiguity inherent to the PLL and estimates the angle of arrival of the source. This procedure is usually linked to high computational complexity that increases with the number of antennas and with the modulation level. This article proposes a technique to decrease the computational burden of the PLL-based single receiver DOA estimation scheme and to use the super resolution algorithm Multiple Emitter Location and Signal Parameter Estimation to obtain azimuth and zenith angles with improved accuracy. The simulated results using the novel algorithm are shown and its performance compared to the traditional solution in different scenarios.
On Equivalent Sphere Illumination (1978)

Under the present equivalent sphere illumination (ESI) system, the actual visibility of a visual task is not known. The author recommends that for every different task and viewing angle, the maximum contrast sensitivity of the task be published; thus, one can determine the ESI required for any given task in order to achieve a certain visibility, or one can obtain task visibility by knowing its ESI value. This broadens the application of the ESI system by enabling conversion between ESI and visibility for a specific task and also conversions among different tasks and viewing angles. Moreover, differences in individual contrast sensitivity response may result in different ESI and visibility from the same task, with the same viewing angle, at the same location under the same luminous environment.
Going global, locally: the socio-technical influences on performance in distributed collaborative learning teams (2002)

With the increasing use of distributed knowledge work in a range of industrial, scientific, and organizational environments, understanding how to support such work has become increasingly important. From previous field and laboratory studies, we know that a range of socio-technical factors influence performance and satisfaction in distributed teams. Among the most important of these factors are trust, leadership and the level of media richness in the computer-mediated communications environment. We also know that specific socio-technical interventions can help to build trust in CMC environments. However, many of these studies have not taken into consideration sufficiently the impact of cross-national cultural factors on distributed teams. This paper reports the preliminary analysis of a thirteen week qualitative and quantitative quasi-experimental field study of distributed collaborative learning teams, consisting of 35 post-graduate students from four research universities, two in the United States and two in South Africa. These teams completed a series of unstructured strategy and decision-making tasks, using a suite of rich-media CMC tools. Data are reported from participant surveys, narrative evaluation essays, and observations.
PMMA Microspheres (Artecoll) for Skin and Soft-Tissue Augmentation. Part II (1995)

Artecoll is an injectable implant for long-lasting correction of wrinkles and other skin defects. Artecoll consists of fine polymethyl-methacrylate (PMMA) microspheres suspended 1:3 in a 3.5% collagen solution. The microspheres are characterized by exceptional surface smoothness, homogenicity, and purity. The size of the microspheres of 30-40 microns diameter is small enough to allow subdermal implantation using a 27-gauge needle. Phagocytosis and dislocation of the implant is prevented by fast encapsulation of each single microsphere with connective tissue. Increased scarring but no granuloma formation has been detected as is common with other injectable implants with irregular surfaces. The experience from more than 600 patients and a prospective study in 118 patients with 200 implantation sites were evaluated. The good early results have continued for 5 years. Of the patients evaluated, 89.5 percent were satisfied and would ask for the treatment again. The overall complication rate is very low, and prolonged redness or visible granules are due to implantations that are too superficial. Other applications in soft-tissue augmentation are discussed.

Conformation and aggregation of melittin: dependence of pH and concentration (1982)

Melittin, a 26-residue peptide from bee venom, is transformed from a largely random to a largely alpha-helical conformation at elevated pH. At 3 x 10(-5) M melittin, circular dichroism spectra show a transition with a pK near 9.6. At 8 x 10(-5) M, two approximately equal transitions occur with pKs at 7.2 and 9.6. At 6 x 10(-4) M, a single transition is seen with a pK of 6.8, followed by a more gradual increase to at least pH 11. The transitions near pH 7 presumably arise from deprotonation of the alpha-amino group. When the amino groups are acetylated or succinylated, a 60% alpha-helical conformation is adopted at neutral or low pH. The acylated melittins form more stable oligomers than does native melittin.

Representation and extraction of volumetric attributes using trivariate splines (2001)

Our goal in this paper is to leverage traditional strengths from the geometric design and scientific visualization communities to produce a tool valuable to both. We present a method for representing and specifying attribute data across a trivariate NURBS volume. Some relevant attribute quantities include material composition and density, optical indices of refraction and dispersion, and data from medical imaging. The method is independent of the granularity of the physical geometry, allowing for a decoupling of the resolution of the carried data from that of the volume. Volume attributes can be modeled or fit to data.
The Power of Power (2017)

Power is a major explanatory concept in the study of social choice. It is used in studies of relations among nations, of community decision making, of business behavior, and of small-group discussion. In order to explore the power of power in empirical theories of social choice, this chapter proposes to do two things: First, it identifies three different variations in this basic approach to power as an intervening variable to suggest the kinds of uses of power. Second, the chapter examines six different classes of models of social choice that are generally consistent with what at least one substantial group of students means by social power. It asks what empirical and technical problems are there in the use of the concept of power and in the use of alternative concepts, and under what circumstances the concept of power does, or can, contribute to the effective prediction of social choice.
Foundations of the Seventh-day Adventist Message and Mission [review] / Damsteegt, P. Gerard. (1979)

This day helps us to find time for others -another almost forgotten art.Yet, the day of rest also takes man beyond the past and present, for it invites one to have "an audience with the future" (p.119).This book offers profound insights, but it is written in a deceptively simple style.It is enhanced by its felicity of expression and sobriety of judgment and will be a wholesome complement to the more technical and occasionally less skillfully executed polemical treatments regarding the day of rest.The Christian Use of Time is sprinkled with refreshing aphorisms and metaphors (e.g., the Sabbath "comes like an unexpected surprise, like a bouquet of flowers when there is no anniversary, birthday, or Mother's Day" [p.281, or again, "It is like a traffic island in the rush of time " [p.391).The work appears to be free from errors in typography and content and comes complete with endnotes and a bibliographical list for further reading.I recommend these reflections to laymen and [especially?J scholars.

Preparation and Properties of Superconducting Glass Ceramics Based on the Bi-Sr-Ca-Cu-O System (1989)

We prepared many bulk glasses in compositions around BiSrCaCu2Ox using the conventional melt quenching method and examined superconducting properties of the glass ceramics obtained. It was found that the compositions in the Bi-Sr-Ca-Cu-O system had a great tendency to form a glass and Bi2O3 played an important role in the glass formation. The glass transition and crystallization temperatures for the glasses of BixSrCaCu2Ow (x=1.2-3) were in the range between 425° and 370°C and in the range between 450° and 430°C, respectively and both values tended to decrease with increasing Bi2O3 content. The ratio of SrO and CaO was also important for the glass formation and the coexistence of SrO and CaO was needed to form a glass. Many glasses became superconducting glass ceramics with the Tc values of around 75K by annealing at 820°C for 40h air.
Information retrieval and spectrum based bug localization: better together (2015)

Debugging often takes much effort and resources. To help developers debug, numerous information retrieval (IR)-based and spectrum-based bug localization techniques have been proposed. IR-based techniques process textual information in bug reports, while spectrum-based techniques process program spectra (i.e., a record of which program elements are executed for each test case). Both eventually generate a ranked list of program elements that are likely to contain the bug. However, these techniques only consider one source of information, either bug reports or program spectra, which is not optimal. To deal with the limitation of existing techniques, in this work, we propose a new multi-modal technique that considers both bug reports and program spectra to localize bugs. Our approach adaptively creates a bug-specific model to map a particular bug to its possible location, and introduces a novel idea of suspicious words that are highly associated to a bug. We evaluate our approach on 157 real bugs from four software systems, and compare it with a state-of-the-art IR-based bug localization method, a state-of-the-art spectrum-based bug localization method, and three state-of-the-art multi-modal feature location methods that are adapted for bug localization. Experiments show that our approach can outperform the baselines by at least 47.62%, 31.48%, 27.78%, and 28.80% in terms of number of bugs successfully localized when a developer inspects 1, 5, and 10 program elements (i.e., Top 1, Top 5, and Top 10), and Mean Average Precision (MAP) respectively.
Synergistic action of MLL, a TRX protein with template activating factor‐I, a histone chaperone (2005)

MLL is involved in the process of gene activity maintenance. It is shown that the amino-terminal region of MLL (MLLN) interacts with TAF-Ibeta/SET. In this study, using yeast two-hybrid assays, we have found that the acidic region of TAF-Ibeta is essential for its binding to MLLN. Pull-down assays using GST-MLLN demonstrated that TAF-Ibeta and histones interact with GST-MLLN. MLLN and TAF-Ibeta synergistically upregulated the transcription level of Hoxa9 and co-immunoprecipitated in chromatin containing the Hoxa9 promoter region. These results suggest that TAF-Ibeta plays an important role in MLL-mediated transcription and possibly chromatin maintenance.
