A splicing factor that is inactivated during in vivo heat shock is functionally equivalent to the [U4/U6.U5] triple snRNP-specific proteins. (1992)

One of the consequences of the heat shock response is a shutdown of pre-mRNA splicing, a phenomenon that can be reproduced in extracts prepared from heat-shocked cells. The block in splicing occurs before the covalent modifications that generate spliced mRNA at the level of spliceosome formation. We have used extracts prepared from heat-shocked cells as a complementation system to characterize and partially purify a protein factor that is inactivated during the in vivo heat shock. The activity functions in the formation of the active spliceosome by assembling U4/U6 and U5 snRNPs into a triple snRNP particle. The factor appears to be different from previously isolated splicing factors and is functionally equivalent to several polypeptides that are specifically associated with the purified triple snRNP but not with individual U4/U6 or U5 snRNPs. Our data confirm the hypothesis that U4/U6 and U5 snRNPs enter the spliceosome as a triple snRNP complex and show for the first time a function of specific snRNP-associated polypeptides in the mammalian splicing pathway.
Region-based memory management for real-time Java (2002)

The paper addresses the issue of improving the performance of memory management for real time Java applications, building upon the Real-Time Specification for Java (RTSJ) from the Real-Time Java Expert Group. In a first step, a thorough analysis of the parameters influencing the performance of memory management together with ways of improvement are presented. The implementation of a memory management solution, which is compliant with the RTSJ and integrating the proposed improvements is then sketched.
INFUSING GERONTOLOGICAL CONTENT INTO CURRICULA: EFFECTIVE CHANGE STRATEGIES (2005)

Abstract This paper presents a review of curriculum-change literature with a special focus on curricular infusion and an analysis of curriculum-change strategies. These strategies were used by 62 social work education programs involved in the national gerontological infusion project supported by the John T. Hartford Foundation. Best practices to achieve gerontological infusion in foundation courses are identified. Curriculum-change strategies that focus on involving all faculty members appear to be strongly supported by the curriculum-change literature and positive outcomes, as shown by the results of the study reported in this paper. The training of faculty and field instructors, the involvement of the foundation faculty as a whole in changing foundation curriculum, and the encouragement of faculty by accepted academic leaders to complete the infusion process, all appear to be key in successfully achieving this kind of curriculum change.
STRUCTURAL BIOCHEMISTRY: II. SYNTHESIS OF 3β-HYDROXY-17β (<scp>L</scp>-PROLYL-<scp>L</scp>-PROLYL)AMINO-5α-ANDROSTANE (1966)

A practical synthetic route to 3β-hydroxy-17β-amino-5α-androstane (III) was developed and the configuration of the amine substituent established by proton magnetic resonance studies. Condensing amine III with carbobenzoxy-L-proline by means of Woodward's reagent K led to proline derivative IVa. Steroidal peptide Vb was readily prepared by first removing the protecting group from amide IVa by palladium-catalyzed hydrogenolysis and then repeating the peptide-forming and hydrogenation steps. Protection of the 3β-hydroxy group proved to be unnecessary, and the presently reported approach to steroidal peptides proved to be reliable and useful.
Fractionation of asphaltenes by gel permeation chromatography (1965)

Asphaltenes from three asphalts of very diverse service properties were fractionated by gel permeation chromatography (GPC) on crosslinked polystyrene gels. Broad molecular weight distributions were found spanning from 700 to more than 40,000. Each sample consisted of two portions of similar quantities, one peaking around 1000 molecular weight, the other around 14,000. The distribution of structural features measured by infrared spectroscopy is discussed briefly.
T-cell responses against tyrosinase 368-376(370D) peptide in HLA*A0201+ melanoma patients: randomized trial comparing incomplete Freund's adjuvant, granulocyte macrophage colony-stimulating factor, and QS-21 as immunological adjuvants. (2002)

We conducted a randomized trial in HLA*A0201+ patientswith American Joint Committee on Cancer stage III or IV melanoma immunized with tyrosinase 368-376(370D) peptide and gp100 209-217(210M) peptide to compare the potency of three different adjuvants. Patients received 3 monthly immunizations with 500 microg of each peptide either with incomplete Freund's adjuvant (IFA), QS-21, or granulocyte macrophage colony-stimulating factor (GM-CSF). The primary end point was induction of IFN-gamma release by CD8+ T cells against tyrosinase and gp100 peptides measured by enzyme-linked immunospot assays without in vitro prestimulation measured pretreatment, 2 and 8 weeks after the third vaccination. Four of 9 and 4 of 8 patients immunized using QS-21 and GM-CSF, respectively, developed increased frequencies of CD8+ T cells against tyrosinase 370D peptide compared with 0 of 9 patients immunized using IFA (P = 0.045). T-cell responses against a gp100-related peptide showed similar results, but their relevance to T-cell reactivity against native gp100 209-217 is uncertain. These results show that: (a) QS-21 and GM-CSF are superior to IFA as immunological adjuvants for vaccination against tyrosinase 370D peptide; and (b) with appropriate adjuvants, increased frequencies of peptide-specific T cells after vaccination can be detected by enzyme-linked immunospot without prolonged prestimulation in vitro.
A Self-Learning Solution for Torque Ripple Reduction for Nonsinusoidal Permanent-Magnet Motor Drives Based on Artificial Neural Networks (2013)

This paper presents an original method, based on artificial neural networks, to reduce the torque ripple in a permanent-magnet nonsinusoidal synchronous motor. Solutions for calculating optimal currents are deduced from geometrical considerations and without a calculation step, which is generally based on the Lagrange optimization. These optimal currents are obtained from two hyperplanes. This paper takes into account the presence of harmonics in the back-EMF and the cogging torque. New control schemes are thus proposed to derive the optimal stator currents giving exactly the desired electromagnetic torque (or speed) and minimizing the ohmic losses. The torque and the speed control scheme both integrate two neural blocks, one dedicated for optimal-current calculation and the other to ensure the generation of these currents via a voltage source inverter. Simulation and experimental results from a laboratory prototype are shown to confirm the validity of the proposed neural approach.

Promoting Higher Education (2001)

ABSTRACT Bibliographic instruction (BI) for high school students by college librarians is a viable form of collaboration between educators at the secondary and college levels. Several different goals for such instruction have been advanced, and a BI session can involve several of these goals simultaneously. The goal of promoting higher education during a BI session for visiting high school students involves discussing the specific resources demonstrated as examples of resources found in a college library and making the tacit assumption that all of the students will eventually pursue higher education. This article reviews the goals of instruction as presented in the literature and suggests that the promotion of higher education is a viable and valuable goal.
A comparative study of distributed resource sharing on multiprocessors (1983)

In this paper, we have studied the interconnection of resources to multiprocessors and the distributed scheduling of these resources. Three different classes of interconnection networks have been investigated; namely, single shared bus, multiple shared buses, and networks with logarithmic delays such as the cube and Omega networks. For a given network, the resource mapping problem entails the search of one (or more) of the free resources which can be connected to each requesting processor. To prevent the bottleneck of sequential scheduling, the type(s) and number(s) of resources desired by a processor are given to the network and it is the responsibility of the network to find the necessary resources and connect them to the processor. The addressing mechanism is, thus, distributed in the network. This is a generalization of conventional interconnection networks with routing tags in which all the resources are of different types.

[Heart surgery in Austria 1995]. (1996)

The European Heart Institute of the European Academy of Sciences and Arts compiles every year since 1990 an annual survey on open heart surgery, PTCA and heart catheterization. Those interventions are on the top of the parameter of cardiac care. These numbers can be used as an outside revision of a country. Within Europe enormous gaps are between incidences in open heart surgery and PTCA. Germany, Austria and Switzerland are in the upper area whereby Germany and Switzerland have near 1,000 operations per million inhabitants. Within the next years, there is a continuous increase in revascularisation by 10% to be expected as well in bypass-surgery and in PTCA. A specific impact is arising in stenting with 30% to 50% at PTCA cases.
Kinetics and mechanism of the anionic polymerization of cyclohexadienes initiated by naphthalene radical anions and dianions (1982)

Abstract The anionic polymerization of 1.3‐cyclohexadiene (1.3‐CHD) was investigated in temperatures that ranged from 25 to −77°C. Initiation by lithium naphthalene (N − ·,Li + ) in tetrahydrofuran at −20°C yields polymers with fairly narrow molecular weight distribution. The M̄ w of these polymers so prepared is ca. 20,000. Polymerization of 1.3‐CHD conducted at room temperature is accompanied by the dehydrogenation and disproportionation of the monomer, especially when N − ·,K + acts as initiator. Oligomers are formed when hexamethylphosphoramide is used as a solvent. The mechanism of the initiation of the polymerization of 1.3‐CHD by N − ·,Li + was elucidated and the rate constants at −20°C in tetrahydrofuran of the elementary reactions were determined. It was established that the dianions formed by disproportionation of N − ·,Li + act as effective initiators for 1.3‐CHD. The adducts formed constitute the cyclohexanyl and naphthyl carbanionic groups. The former carbanions (λ max ∼ 275 nm) propagate the polymerization. The initially formed dimeric adducts are stabilized by the separation of the carbanionic end groups by the additional monomer units. Chain transfer to the monomer limits the growth of the polymers. The isomerization of the cyclohexadienyl anions, formed as result of chain transfer, may be followed by the elimination of lithium hydride. The latter reaction represents a termination step. Addition of 1.4‐CHD to the reaction mixture enhances the chain transfer and the termination.
A novel broad-band Chebyshev-response rat-race ring coupler (1999)

A novel broad-band rat-race ring coupler with a unit element at each port and an ideal phase inverter at one of the ring arms is proposed and analyzed. Design equations based on Chebyshev equiripple functions are derived. The design curves of equal or unequal power division are also presented. Theoretical data show that the bandwidth of unequal power division with a specific return-loss value increases as the power division ratio increases or decreases from unity. For a 180/spl deg/ hybrid with equal power division (3 dB) and 15-dB return loss, the proposed rat-race ring may have a bandwidth of 4:1. Three circuits of this novel rat-race ring are realized using finite-ground-plane coplanar waveguide. The measured results match very well with the theory.
The Strengths of Fiber Reinforced Composite Bends (1986)

An analysis is presented for calculating the stresses and strains in bends made of fiber reinforced composites and for estimating the strengths of bends. The stress field is calculated by a finite element method. The strength is predicted using the Tsai-Hill criterion for inplane failure and the Chang-Springer criterion for out of plane failure. Results are presented which illustrate the effects of geometry and ply orientation on the strength and on the mode of failure.
Chemical Modification and Structure-activity Relationships of Pyripyropenes. 2. 1,11-Cyclic Analogs. (1996)

A series of 1,11-cyclic analogs of pyripyropene A were prepared. Replacement of the 1,11-acyl groups of pyripyropenes with 1,11-cyclic acetals effectively improved in vitro acyl CoA:cholesterol acyltransferase (ACAT) inhibitory activity. Especially noteworthy is benzylidene acetal analog 35, the most potent inhibitor (IC50 = 5.6 nM) among the derivatives prepared so far, which showed 16 times more potent inhibitory activity than pyripyropene A.
Anti-theft energy metering for smart electrical distribution system (2015)

Accurate metering and billing of actual energy consumed by consumers is integral to commercial management of an electric utility. An aggregate technical and commercial loss in India is around 27% and this is very high in spite of various reforms and measures by electricity boards across country. One of the significant components of these losses is Theft. Electricity theft is a grave problem across the globe. Improvement in aggregate technical and commercial losses in phased manner is very important for financial and technical viability of distribution companies in deregulated environment. The major challenge is to identify the location of the theft and estimate the amount of energy being stolen. Research to identify power pilferages and remedial measures to overcome them in electricity sector has been going on in recent years. The Paper proposes a conceptual approach to get both the approximate location and estimate of energy theft at that location. With both information available in real time, it will completely change the landscape of electrical sector across the nation.

Editorial (1986)

The life of Albert Speer should be a required study for aspiring technical specialists all over the world. For those unfamiliar with him, Speer was Adolf Hitler's confidant as well as chief architect and later Minister of Armaments for Nazi Germany during World War II. For his part in the war effort, Speer was sentenced to 20 years of imprisonment by the Allied Tribunal at Nuremburg. While serving time, he maintained a fascinating prison diary which has been published as Spandau: The Secret Diaries (New York: Macmillan, 1976). His autobiography, entitled Inside the Third Reich (New York: Macmillan, 1970), has been used by many to study the inner workings of Hitler's Germany.
The Effectiveness of Silane and Siloxane Treatments on the Superhydrophobicity and Icephobicity of Concrete Surfaces (2013)

Icy roads lead to treacherous driving conditions in regions of the U.S., leading to over 450 fatalities per year. De-icing chemicals, such as road salt, leave much to be desired. In this report, commercially available silane, siloxane, and related materials were evaluated as solutions, simple emulsions, and complex emulsions with incorporated particulates, for their effectiveness as superhydrophobic treatments. Through the development and use of a basic impact test, the ease of ice removal (icephobicity) was examined as an application of the targeted superhydrophobicity.\nA general correlation was found between icephobicity and hydrophobicity, with the amount of ice removed on impact increasing with increasing contact angle. However, the correlation was poor in the high performance region (high contact angle and high ice removal.)\nPolymethylhydrogensiloxane was a top performer and was more effective when used as a "shell" type emulsion with silica fume particulates. An aqueous sodium methyl siliconate solution showed good performance for ice loss and contact angle, as did a commercial proprietary emulsion using a diethoxyoctylsilyl trimethylsilyl ester of silicic acid. These materials have sterically available functional groups that can react or associate with the concrete surface and are potentially film-forming. Materials with less reactive functional groups and a lower propensity to film-form did not perform as well.
Clean Carbon Nanotube Field Emitters Aligned Horizontally (2006)

Horizontally aligned carbon nanotube (CNT) field emitters, which strongly adhere to the substrate and show good field emission properties, were fabricated by electrophoresis deposition and fissure formation techniques. A thin film of CNTs was deposited on a substrate, by electrophoresis, from an aqueous mixture of CNT and detergent, and then the detergent was deposited also by electropholysis. CNTs with a clean surface were exposed in the fissures produced by firing. The field emission was increased significantly due to the additional deposition of the detergent. When the CNTs were cut by increasing the firing time, the field emission increased significantly, while their stability decreased considerably. Our method does not require any further treatment for field emission.
CXCR3 Deficiency Exacerbates Liver Disease and Abrogates Tolerance in a Mouse Model of Immune-Mediated Hepatitis (2011)

The chemokine receptor CXCR3 is preferentially expressed by Th1 cells and critically involved in their recruitment to inflamed tissue. In a mouse model of immune-mediated liver injury inducible by Con A, we investigated the role of CXCR3 in acute IFN-γ-mediated hepatitis as well as in tolerance induction, which has been shown to depend on IL-10-producing CD4(+)CD25(+)Foxp3(+) regulatory T cells (Tregs). Induction of Con A hepatitis resulted in increased intrahepatic expression of the CXCR3 ligands CXCL9, CXCL10, and CXCL11. CXCR3(-/-) mice developed a more severe liver injury with higher plasma transaminase activities and a more pronounced Th1/Th17 response compared with wild-type (wt) animals upon Con A injection. Moreover, CXCR3(-/-) mice did not establish tolerance upon Con A restimulation, although Tregs from CXCR3(-/-) mice were still suppressive in an in vitro suppression assay. Instead, Tregs failed to accumulate in livers of CXCR3(-/-) mice upon Con A restimulation in contrast to those from wt animals. Con A-tolerant wt mice harbored significantly increased numbers of intrahepatic CXCR3(+)T-bet(+) Tregs that produced IL-10 compared with nontolerant animals. IFN-γ deficiency or anti-IFN-γ Ab treatment demonstrated that conversion to CXCR3(+)T-bet(+) Tregs depended on a Th1 response. Accordingly, in an immunotherapeutic approach, CD4(+)CD25(+)Foxp3(+) Tregs from Con A-pretreated CXCR3-deficient mice failed to protect against Con A-induced hepatitis, whereas Tregs from Con A-tolerant wt mice allowed CXCR3-deficient mice to recover from Con A hepatitis. In summary, CXCR3(+)T-bet(+)IL-10(+) Tregs are generated in the liver in dependence of IFN-γ, then disseminated into the organism and specifically migrate into the liver, where they limit immune-mediated liver damage.
