Isolation of a novel macrophage-specific gene by differential cDNA analysis (1995)

To analyze myelomonocytic differentiation we have used the approach of differential cDNA analysis to isolate novel genes that are preferentially expressed in mature macrophages. Differential screening of a macrophage cDNA library led to the identification of a novel cDNA that showed macrophage lineage- and differentiation stage-specific expression. Transcripts from the gene, which we have termed Mpg-1, are found at a high level in mature human and murine macrophages and at a moderate level in certain myelomonocytic cell lines. The expression of Mpg-1 was found to increase when murine fetal liver hematopoietic progenitor cells were induced to differentiate into macrophages. An Mpg-1-specific transcript was not detected in a wide variety of other tissues and cell lines. The DNA sequence of Mpg-1 (4,214 bp) was obtained from a series of overlapping cDNA, 3' rapid amplification of cDNA ends (RACE), and genomic clones. Primer extension analysis predicted the existence of multiple transcription start sites, ranging from 26 to 117 bp upstream of the 5' proximal ATG of the open reading frame. The predicted 669-amino acid, Mpg-1-encoded protein has potential glycosylation and phosphorylation sites in addition to a signal sequence. The core protein is predicted to have a molecular weight of 71 to 74 kD. Computer-assisted local similarity searches indicate that Mpg-1 is a novel gene that may share a distant ancestry to perforin, a lytic protein found in cytotoxic T lymphocytes and natural killer cells.
Using Image Processing and A new SAFT Algorithm for Ultrasonic Flaw Imaging in Concrete (2000)

The Synthetic Aperture Focusing Technique (SAFT) is well established for ultrasonic imaging purposes, for example in nondestructive testing (NDT) of materials. The ultrasonic inspection of concrete is notoriously difficult however, due to its combined attenuating and scattering characteristics, especially at high frequencies. Since low frequency transducers must be used, inspection has traditionally been limited to rather simple measurements conducted in the time domain, such as the ultrasonic pulse velocity. Since the propagation velocity is related to the modulus and density, and hence indirectly to the strength of concrete, the pulse-velocity method has been established as possibly the only standard technique of nondestructive testing of concrete. It is of limited value when attempting to establish the internal condition of the material. For cases where the interrogation frequency is very low (below 250kHz), normally the transducers do not have a broadband frequency response, which causes prolonged ringing in the time domain. Recently however, advances in transducer technology and signal processing have enabled the direct visualization of internal defects both by using pulse-echo systems and SAFT the development and application of an enhanced time-domain SAFT algorithm that uses a correlation technique to perform the coherence summation. Not only is this method faster, by an order of magnitude, than equivalent time-domain SAFT algorithms, it produces images of defects within the concrete that are unobtainable by other means of processing the ultrasonic signals.
Synthesis and characterization of the biodegradable copolymers from succinic acid and adipic acid with 1,4‐butanediol (2001)

Biodegradable homopolyesters such as poly(butylene succinate) (PBSU) and poly(butylene adipate) (PBAD) and copolyesters such as poly(butylene succinate-co-butylene adipate) (PBSA) were synthesized, respectively, from succinic acid (SA) and adipic acid (AA) with 1,4-butanediol through a two-step process of esterification and deglycolization. The polyester compositions and physical properties of both homopolyesters and copolyesters were investigated by 1H– and 13C–NMR, DSC, GPC, WAXD, and optical polarizing microscopy. The melting point (Tm) of these copolyesters decreased gradually as the contents of butylene adipate increased and the glass-transition temperature (Tg) of these copolyesters decreased linearly as the contents of the adipoyl unit increased. PBSA copolyesters showed two types of XRD patterns of PBSU and PBAD homopolyesters. Furthermore, the biodegradation and hydrolytic degradation of the high molecular weight PBSU homopolyester, PBAD homopolyester, and PBSA copolyesters were investigated in the composting soil and NH4Cl aqueous solutions at a pH level of 10.6. © 2001 John Wiley & Sons, Inc.

The paper discusses the history behind the study of anatomy and how the study of anatomy can be used a foil to discuss religious, social, and cultural implications.
Automatically generating tutorials to enable middle school children to learn programming independently (2013)

Enabling middle school children to learn from code shared on the internet may provide computer science learning opportunities to those who would not otherwise have them. We augmented a programming environment designed for middle school children to automatically generate tutorials from code snippets in order to help users learn new programming skills. In our new system, users select code snippets from a program shared on the web and then complete an automatically generated tutorial in order to re-create that snippet within their own program. To evaluate the potential learning gains from our generated tutorials, we conducted a between-subjects study in which we evaluated the performance of children introduced to new programming constructs through automatically generated tutorials. Participants who used the automatically generated tutorials performed 64% better on a near transfer task compared to participants without generated tutorials.
The Chair: Rethinking Culture, Body, and Design (1998)

Perhaps no other object of our daily environment has had the enduring cultural significance of the ever-present chair, unconsciously yet forcefully shaping the physical and social dimensions of our lives. With over ninety illustrations, this book traces the history of the chair as we know it from its crudest beginnings up through the modern office variety. Drawing on anecdotes, literary references, and famous designs, documents our ongoing love affair with the chair and how its evolution has been governed not by a quest for comfort or practicality, but by the designation of status.Relating much of the modern era's rampant back pain to an increasingly sedentary lifestyle spent in traditional seating, goes beyond traditional ergonomic theory to formulate new design principles that challenge the way we think and live. A farsighted and innovative approach to our most intimate habitat, this book offers guidelines that will assist readers in choosing a chair-and designing a lifestyle-that truly suits our bodies. Praise for The Chair: [A] concise, multidisciplinary gem.-Publishers Weekly Cranz is no sedentary historian. The Chair is a call to action. -Jonathan Levi, Los Angeles Times Galen has written a provocative book. Pull up a comfortable chair-if you can find one-and read it.-Witold Rybczynski
A relational view of the data independent accessing model (1976)

Efficiency is of paramount importance in very large databases. A principal technique for increasing efficiency is to define the user's view of the data independently of the storage structure so that the storage structure can be varied at will to improve performance. A widely accepted user view for this purpose is the relational model [3] and substantial progress has been made since its introduction. Far less research has been devoted to fundamental models of storage structures and the only comprehensive treatment is the Data Independent Accessing Model (DIAM) [1]. The DIAM, however, has seen limited application due, at least in part, to its use of the (less popular) entity set view of data. And despite the close correspondence between the relational and entity set views [2], little has been done to exploit their similarities. This paper attempts to show that the DIAM's relevance to contemporary research in database systems can be enhanced by viewing it through n-ary relations. To accomplish this, the paper first develops a redefinition of the DIAM String Level in terms of n-ary relations. It then appeals to the remaining levels of the DIAM to describe various relational implementation alternatives. The paper concludes that the utility of both the DIAM and the relational model is enhanced by this approach.
Waiting for Marina: Generosity and shared time in Marina Abramovic's 512 Hours (2018)

This presentation examines Marina Abramović’s performance, 512 Hours (Serpentine Gallery, London, 2014) as a catalyst for thinking about forms of criticality needed to respond to contemporary conditions of neoliberal culture. I ask what kind of criticality, if any, is generated by the project and how this is informed by the artist’s history of ‘endurance performances’, which test the limits of her bodily and emotional strength. In this pared down performance Abramović was present in the gallery between 10am-6pm, six days a week between 11 June and 25 August. Building on her critically acclaimed 2010 performance at the Museum of Modern Art, New York, The Artist Is Present, much was made in the weeks preceding 512 Hours of the idea of doing nothing with Abramović. However, as with many performances in which it appears that nothing is happening, 512 Hours was replete with expectation and reminded participants that not being busy is not the same as doing nothing. In this presentation, I examine what this realization can offer as a critique of neo-liberal imperatives to produce tangible outcomes, act in a purposeful way and measure productivity. \n\n512 Hours is an intensely affective performance. It invited participants to slow down and dispense with the pressures of everyday life. Drawing on Jennifer Doyle’s brilliant critique of art criticism’s derogatory attitude towards ‘feelings’, my intention here is to fold argument into experience of the performance and to suggest that the emotional aspect of 512 Hours is not detached from its critical potential. By focussing on one performance in detail, my aim is to explore Abramović’s use of slowness as a medium with which to engage affectively with others. My hypothesis is that this slowness opens up a new approach to criticality, which takes generosity and shared time as its key drivers.
Isolation of a sulfate-reducing bacterium growing with methanol (1986)

The possible role of sulfate-reducing bacteria in the anaerobic mineralization of methanol is discussed.
SYNTHESIS AND<sup>31</sup>P AND<sup>13</sup>C NMR STUDIES OF PYROPHOSPHONIC ACIDS (1992)

Abstract Pyrophosphonic acids were prepared by partial hydrolysis of phosphonic acid dichlorides and by de-hydration of phosphonic acids, respectively. The pyrophosphonic acids as well as their ammonium salts were characterized by NMR spectroscopy. The geminal coupling constant 2JPOP was obtained from spectral analysis and its sign was determined by spin tickling experiments. Furthermore, semiempirical quantum chemical calculations of 2JPOP were carried out.
Compilation of tRNA sequences and sequences of tRNA genes (2004)

Maintained at the Universitat Bayreuth, Bayreuth, Germany, the Compilation of tRNA Sequences and Sequences of tRNA Genes is accessible at the URL http://www.tRNA.uni-bayreuth.de with mirror site located at the Institute of Protein Research, Pushchino, Russia (http://alpha.protres.ru/trnadbase). The compilation is a searchable, periodically updated database of currently available tRNA sequences. The present version of the database contains a new Genomic tRNA Compilation including the sequences of tRNA genes from genomic sequences published up to July 2003. It consists of about 5800 tRNA gene sequences from 111 organisms covering archaea, bacteria, higher and lower eukarya. The former Compilation of tRNA Genes (up to the end of 1998) and the updated Compilation tRNA Sequences (561 entries) are also supported by the new software. The database can be explored by using multiple search criteria and sequence templates. The database provides a service that allows to obtain statistical information on the occurrences of certain bases at given positions of the tRNA sequences. This allows phylogenic studies and search for identity elements in respect to interactions of tRNAs with various enzymes.
Performance analysis of high‐performance file‐transfer systems for Grid applications (2005)

Abstract Data‐intensive Grid applications require the availability of tools able to transfer very large files in the shortest amount of time. Many file‐transfer tools, based on solutions aimed at overcoming the limitations imposed by the TCP protocol, have recently been developed. In this paper we experimentally compare the performance of some of these tools in various network scenarios by running experiments on PlanetLab, an open platform for the development, deployment, and access of planetary‐scale services, that comprises hundreds of hosts scattered across the globe. Our results show that solutions based on UDP and adopting rate‐based algorithms result in better performance than other alternatives in most cases, while solutions based on TCP achieve similar performance only under specific circumstances.

Synthesis of Quinolizine Derivatives. VI (1959)

As a part of studies on the syntheses of substances with sparteine-like activity, quinolizidine derivatives possessing a basic side-chain at 3-position were prepared. Following the separation of ethyl 3-quinolizidinecarboxylate and ethyl 3-epi-quinoli-zidinecarboxylate, and determination of their configuration, respective hydrazides were prepared and their Curtius degradation afforded 3-aminoquinolizidine (VIa) and 3-epi-aminoquinolizidine. It was found during the course of this reaction that there was a difference in the mode of reaction to Curtius degradation according to the configuration of the hydrazide. 3-Benzylaminoquinolizidine was prepared by a difference route and formation of 3-epi-benzylamino compound was observed.

Theoretical foundation and the characteristics of these crypto ciphers and other asymmetric once are analyzed. The considered metrics of cryptographic schemes include cryptographic strength, performance, public key size and length of ciphertext. The binary Goppa codes and their role in ensuring the cryptanalytic resistance of these systems are described. The main advantages and drawbacks of these cryptosystems are analyzed. Outlines the possible application of these ciphers to the network security protocols are discussed including the search for ways to reduce the public key sizes of these cryptographic schemes and improve their energy efficiency.
Considerations in the choice of surgical needles. (1979)

Bodily tissues of varying consistency, thickness, penetrability, location and weave are encountered by the surgeon. Correspondingly, he should choose surgical needles that will introduce sutures through these tissues in the most precise and rapid manner, ideally creating a wound just large enough to draw the suture material into and through the tissue. Manipulation of the needle is aided by selecting one appropriate to the specific wound site and by the choice of a needle holder that is most ideally suited to the particular needle. Although the primary reason for appropriate choice of needle and needle holder is better patient care, an extremely important secondary reason is greater comfort and satisfaction for the surgeon in using ideal instruments.
Temperature Behavior of the Electrical Conductivity of Emim-Based Ionic Liquids in Liquid and Solid States (2007)

In this paper we present experimental measurements of the temperature dependence of the electrical conductivity, , in four ionic liquid compounds (ILs) in both the liquid and solid states and at atmospheric pressure. The chemicals measured are composed by the 1-ethyl-3-methyl-imidazolium (EMIM + ) cation, which has been combined with four different anions: Cl -, Br -, BF 4 -and ethyl sulfate (ES -). In the liquid state, the temperature dependence of , for the four ILs follows the Vogel-Tamman-Fulcher (VTF) equation with high precision. Around the transition between the solid and liquid states, the electrical conductivity of the three ILs with lighter anions presents an hysteresis loop, that can be explained as the apparition of supercooled liquid. In contrast, the EMIM-ES presents a smooth transition, without any jump in the , value or any hysteresis loop (probably because its melting point is reported to be below the minimum temperature measured by us). Finally, the jump in , is not related with the glass transition because its temperature value is well below the minimum temperature measured, and at that glass transition temperature the , value is below the resolution of our conductivity meter (2 nS/cm).
Glutaraldehyde-Treated Carrier Erythrocytes for Organ Targeting of Methotrexate in Dogs (1981)

Chemotherapeutic doses of methotrexate (MTX) were encapsulated in as little as 1 ml of canine carrier erythrocytes. Carrier erythrocytes prepared by a dialysis technique contained more than 3.0 mg of MTX/ml of cells. In vivo pharmacokinetic studies indicated that most of the drug leaked from the circulating MTX-loaded erythrocytes. In dogs, glutaraldehyde treatment of MTX-loaded erythrocytes prevented drug leakage and targeted more than 50% of the drug to the liver.
[Conformation transformation of lead in rhizosphere]. (2002)

With rhizoboxes, this study dealt with the distribution and conformation transformation of lead in the rhizosphere and non-rhizosphere of wheat and rice grown on red soil. The results showed that the predominant forms of lead were acid dissolved and Carb-Pb (bound to carbonates), Exch-Pb (exchangeable-Pb), and FeMnO-Pb (boud to iron and manganese oxides). Exch-Pb in the rhizosphere of both rice and wheat was much higher than those in the non-rhizosphere, which means that the activation process in the rhizosphere was very strong, and bio-available Pb greatly increased. Various levels of Pb treatment and Pb-Cd interaction also had certain effects on the distribution of lead. In treatment of low Pb concentration, FeMnO-Pb was higher than Exch-Pb, but the contrary result was observed in treatment of high Pb concentration. Both Exch-Pb and FeMnO-Pb in wheat rhizosphere decreased with an increase of Cd. Exch-Pb in rice rhizosphere was correlative to the Cd content in soil. Compared with the treatment in the absence of Cd, the activation of Exch-Pb in rice rhizosphere was weaker in 5 mg Cd.kg-1 treatment, but stronger in 10 mg Cd.kg-1 treatment.
Structural Behavior of Flexurally Reinforced FRP-Concrete Composite Compression Member with FRP (2010)

In construction industries, new construction materials are needed to overcome some problems associated with the use of conventional construction materials due to the change of environmental and social requirements. Accordingly, the requirements to be satisfied in the design of civil engineering structures are diversified. As a new construction material in the civil engineering industries, fiber reinforced polymeric plastic (FRP) has a superior corrosion resistance, high specific strength/stiffness, etc. Therefore, such properties can be used to mitigate the problems associated with the use of conventional construction materials. Nowadays, new types of bridge piers and marine piles are being studied for new construction. They are usually made of concrete filled fiber reinforced polymeric plastic tubes (CFFT). In this paper, a new type of FRP-concrete composite pile which is composed of reinforced concrete filled FRP tube (RCFFT) is proposed to improve compressive strength as well as flexural strength. The load carrying capacity of proposed RCFFT compression member is discussed based on the result of experimental and analytical investigations.
A 6-DOF force-reflecting hand controller using the fivebar parallel mechanism (2002)

A force-reflecting hand controller can provide the kinesthetic information obtained from a slave manipulator to the operator of a telerobotic system. Our goal is to construct a compact hand controller that can provide large workspace and good force-reflecting capability. This paper presents the design and the analysis of a 6-DOF force-reflecting hand controller using fivebar parallel mechanisms. The forward kinematics of the fivebar parallel mechanism has been calculated in real-time using three pin-joint sensors in addition to six actuator position sensors. A force decomposition approach is used to compute the Jacobian. To evaluate the characteristics of the fivebar parallel mechanism, it has been compared with the other three parallel mechanisms in terms of workspace and manipulability measure. The hand controller using the fivebar parallel mechanism has been constructed and tested to verify the feasibility of the design concept and the force reflecting control schemes.
Treatment of neuroleptic induced akathisia with the 5-HT2 antagonist ritanserin. (1990)

Akathisia is a frequent and distressing side effect of antipsychotic medication. Little is known about its pathophysiology. Treatment trials of serotonin antagonists in Parkinson's disease and neuroleptic-induced Parkinsonism have been disappointing, with the possible exception of akathisia which has been reported to respond favorably to ritanserin. We report first results of a single-blind trial of ritanserin in the treatment of neuroleptic-induced akathisia. Ten patients received a mean dose of 13.5 mg/day (SD +/- 5.8) ritanserin for 2 to 4 days. Treatment response was assessed by the Hillside Akathisia Scale (HAS). HAS baseline ratings were 16.4 (+/- 6). After 3 days of treatment, these values dropped to 7.4 (+/- 5.2). This amelioration was statistically significant (p = .0069 matched-pairs signed rank test). Two patients did not respond. These results, although preliminary in nature, are encouraging and warrant further studies.
Spin relaxation effects in the perpendicular magnetoresistance of magnetic multilayers (1995)

The spin-diffusion length is the scaling length of the perpendicular giant magnetoresistance in magnetic multilayers and, according to recent experiments, the magnetoresistance ratio can be significantly reduced by enhancing the spin relaxation and thus shortening the spin-diffusion length. We present a theoretical picture of these spin-diffusion-length effects on the magnetoresistance. We also calculate the contribution from several mechanisms (spin-orbit scattering, exchange scattering by paramagnetic impurities, electron-magnon scattering) to the spin relaxation and spin-diffusion length.
Optically active biological particle distinguishing apparatus (2013)

The disclosure is directed to organic particle sorting and identification. High frequency pulses of circularly polarized light, alternating between left and right, intersect a fast moving stream of organic particles. Circular intensity differential scattering and linear intensity differential scattering are monitored to uniquely identify a variety of organic particles.
Acyclovir treatment for linear endotheliitis on grafted corneas (1996)

Two patients with previous corneal transplants developed unusual rejection-like episodes of the grafted cornea. Both had a migrating line of keratic precipitates and stromal edema involving both the donor and recipient corneas. Intensive steroid treatment attained little effect, but oral acyclovir treatment dramatically suppressed the disease process. The facts suggest that a virus-related immune mechanism against both the donor and recipient endothelia, rather than simple allograft rejection, may have been responsible for the clinical presentations. Oral acyclovir therapy might be considered in patients with steroid-nonresponsive corneal endotheliitis mimicking allograft rejection.
