Photoportals (2014)

Photoportals build on digital photography as a unifying metaphor for reference-based interaction in 3D virtual environments. Virtual photos and videos serve as threedimensional references to objects, places, moments in time and activities of users. Our Photoportals also provide access to intermediate or alternative versions of a scenario and allow the review of recorded task sequences that include life-size representations of the captured users. We propose to exploit such references to structure collaborative activities of collocated and remote users. Photoportals offer additional access points for multiple users and encourage mutual support through the preparation and provision of references for manipulation and navigation tasks. They support the pattern of territoriality with configurable space representations that can be used for private interaction, as well as be shared and exchanged with others.
LALNVIEW: a graphical viewer for pairwise sequence alignments (1996)

LALNVIEW is a graphical program for visualising local alignments between two sequences (protein or nucleic acids). Sequences are represented by coloured rectangles to give an overall picture of their similarities. LALNVIEW can display sequence features (exon, intron, active site, domain, propeptide, etc.) along with the alignment. When using LALNVIEW through our Web servers, sequence features are automatically extracted from database annotations (SWISS-PROT, GenBank, EMBL or HOVERGEN) and displayed with the alignment. LALNVIEW is a useful tool for analysing pairwise sequence alignments and for making the link between sequence homology and what is known about the structure or function of sequences. LALNVIEW executables for UNIX, Macintosh and PC computers are freely available from our server (http:// expasy.hcuge.ch/sprot/lalnview.html).
Prime: Byzantine Replication under Attack (2010)

Existing Byzantine-resilient replication protocols satisfy two standard correctness criteria, safety and liveness, even in the presence of Byzantine faults. The runtime performance of these protocols is most commonly assessed in the absence of processor faults and is usually good in that case. However, faulty processors can significantly degrade the performance of some protocols, limiting their practical utility in adversarial environments. This paper demonstrates the extent of performance degradation possible in some existing protocols that do satisfy liveness and that do perform well absent Byzantine faults. We propose a new performance-oriented correctness criterion that requires a consistent level of performance, even with Byzantine faults. We present a new Byzantine fault-tolerant replication protocol that meets the new correctness criterion and evaluate its performance in fault-free executions and when under attack.

Hypobetalipoproteinemia Due to an Apolipoprotein B Gene Exon 21 Deletion Derived by Alu-Alu Recombination (1989)

We report the molecular defect in an individual with homozygous hypobetalipoproteinemia. A unique TaqI restriction fragment length polymorphism was found in the midportion of the apolipoprotein B (apoB) gene using the genomic probe, pB51. The probe, which identifies TaqI fragments of 8.4 and 2.8 kilobases (kb) in normal individuals, hybridized to a single 11-kb fragment in the proband. The parents of the proband showed all three TaqI fragments, implying that they are heterozygotes for the mutant apoB allele. In this family, the mutant allele cosegregated with low total cholesterol levels and formal linkage analysis gave a decimal logarithm of the ratio score of 3.3 at a recombination frequency of 0. The polymorphic TaqI site was localized to an EcoRI fragment of 4 kb in normal individuals. The corresponding fragment in the proband was 3.4 kb, suggesting a 0.6-kb deletion in the mutant allele. Both the normal 4-kb EcoRI fragment and the mutant 3.4-kb EcoRI fragment were cloned and sequenced. In the normal allele, the 4-kb EcoRI fragment extends from intron 20 to 23. Exon 21 is flanked by Alu sequences that are in the same orientation. The mutant allele had a 694-bp deletion in this region which included a small part of the Alu sequence in intron 20, the entire exon 21, and most of the Alu sequence in intron 21. The polymorphic TaqI site, which lies within the Alu sequence in intron 21, was absent in the proband as a result of the deletion. The deletion of exon 21 results in a frame shift mutation and the introduction of a stop codon. Translation of the encoded mRNA would yield a prematurely terminated protein. This mutant apoB protein would be 1085 amino acids long with the 73 carboxyl-terminal residues out of frame. We postulate that the deletion of exon 21 is the consequence of a crossover event between the Alu sequences in introns 20 and 21 resulting in nonreciprocal exchange between two chromosomes.
Switched-source-impedance CMOS circuit for low standby subthreshold current giga-scale LSI's (1993)

A switched-source-impedance (SSI) CMOS circuit is proposed as a means of reducing the exponential increase of subthreshold current with threshold-voltage scaling. Inserting a switched impedance at the source of a MOS transistor reduces the standby subthreshold current of giga-scale LSI's operating at room temperature by three to four orders of magnitude and suppresses the current variation caused by threshold-voltage and temperature fluctuations. The scheme is applicable to any combinational and sequential CMOS logic circuits as long as their standby node voltages are predictable. The standby current of a 16-Gb DRAM is expected to be reduced from 1.1 A to 0.29 mA using this scheme. Hence, battery backup of giga-scale LSI's will be possible even at room temperature and above.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effects of Axial Weight Loading on Gait for Subjects with Cerebellar Ataxia (2003)

Background and Purpose: Weighting the axial skeleton has been recommended to improve gait for patients with ataxia. In this study the effect of axial loading on gait of individuals with cerebellar ataxia was examined. Subjects and Methods: Five subjects with ataxic gait ambulated 9.76 meters for 5 trials in each of 4 conditions: an initial unweighted phase, with weight at the shoulders, with weight at the waist, and a final unweighted phase in a repeated ABCA single-subject design. Footfall characteristics were recorded for 3.66 meters of each trial using a GAITRite® mat. The two standard deviation band method was used to analyze 6 gait parameters: velocity, cadence, standard deviation of step time, standard deviation of step length, width of the base of support, and double stance time. Results: Gait characteristics changed unpredictably in the 4 conditions, worsening more often than improving. Discussion: Effects of axial loading on gait were inconsistent. Conclusion: Using axial weights to improve gait for patients with ataxia was not supported.
Evaluation of Mass Spectrometric Methods Applicable to the Direct Analysis of Non-Peptide Bead-Bound Combinatorial Libraries (1996)

Electrospray, matrix-assisted laser desorption, and time-of-flight secondary ion mass spectrometry have been explored as possible methods for the identification of active members of molecular combinatorial libraries. All three methods are found to yield accurate molecular weight information about a target molecule angiotensin II antagonist synthesized on a 40-microns polystyrene bead. Structural identification is also possible by accurate mass measurements to eliminate candidate structures with the same nominal mass and by analysis of the fragmentation patterns. In addition, the secondary ion mass spectrometry measurements yield spatially resolved spectra from a single bead after exposure to a suitable gas which clips the covalent bond at the linking position. All three approaches appear to offer a viable screening strategy of non-peptide libraries without the use of additional molecular tags.
Minnesota 4-H Science of Agriculture Challenge: Infusing Agricultural Science and Engineering Concepts into 4-H Youth Development (2016)

Youth involved in 4-H projects have been engaged in science-related endeavors for years. Since 2006, 4-H has invested considerable resources in the advancement of science learning. The new Minnesota 4-H Science of Agriculture Challenge program challenges 4-H youth to work together to identify agriculture-related issues in their communities and to work with local experts, using scientific and engineering principles, to devise real solutions for those issues. The Minnesota 4-H Science of Agriculture Challenge program has the potential to change the way scientific and engineering principles are integrated into 4-H youth development programming.

Abstract:- A new approach for contour data approximation and compression algorithm is presented in the paper. Cartesian co-ordinates of an input contour are processed in such a manner that finally contours is presented by selected vertices of the edge of the contour. In the paper the main idea of the proposed procedure and compression of analysed method with the Ramer and the Tangent methods of contour approximation are performed. To compare the results, the mean square error and signal-to-noise ratio criterions were used. Number of operations that is necessary to perform approximation and compression procedures is also presented. The simplicity and the small number of operations are the main advantages of the proposed algorithm. Key-Words:- contour representation, contour compression, polygonal approximation, Ramer and Tangent methods. 1
What can computer programs do to facilitate negotiation processes? (1991)

Recently, there has been considerable interest in the development of computer systems for use in negotiations.However, these systems are exclusively focussed on joint problem solving in cooperative settings.This paper concentrates on negotiation situations that are marked by conflict.Using a social-theoretic framework we identify the scope of computer assistance for negotiation in non-cooperative situations.We focus on the descriptive part of Raiffa's asymmetric descriptive/prescriptive strategy for competitive decision-making.An outline of a software system is presented.Such a system can help build a database of negotiation case histories that can be represented graphically.We explore its use in competitive bargaining situations where the system can provide a descriptive model of the opponents' bargaining behavior and help classify a negotiator in terms of negotiation strategies he is inclined to use.This allows the user to adopt a prescriptive approach in t~.process of concession-making in negotiations.The principles of a computer program -FACILITATOR -to facilitate the process of negotiation are also presented.
Differential patterns of anti‐tumour drug responses and mechanisms of resistance in a series of independently‐derived VP‐16‐resistant human tumour cell lines (1988)

Resistance to etoposide, which was expressed following exposure of a human tumour cell line (HN-I) to fractionated X-irradiation (II fractions to a total dose of 50Gy), was found to be exhibited after delivery of only 5 fractions (total dose of 22.5Gy). In addition, 2 new etoposide-resistant sublines of these HN-I cells have been developed by continuous exposure in vitro to sublethal drug concentrations. No significant differences in growth characteristics were shown between all these resistant sublines and the parental line. The drug-treated line, HN-I/VP-2, expressed cross resistance to vincristine, adriamycin and daunomycin, and marginal cross resistance to vinblastine and cisplatin. The X-irradiation-treated subline (HN-I/DXR-II) also proved cross-resistant to vincristine and marginally cross-resistant to vinblastine, but showed unaltered responses to adriamycin and daunomycin, and expressed marginal collateral sensitivity to cisplatin. Comparisons of drug-uptake characteristics showed that only the HN-I/VP2 cells and not the HN-I/DXR-II cells had reduced uptake of vincristine, vinblastine and daunomycin. However, etoposide uptake was not altered in either resistant subline. Further investigations have shown that the approximately 4-fold level of resistance to etoposide in these HN-I/VP-2 and HN-I/DXR-II cells was associated with a reduction in etoposide-induced DNA single-strand breakage. However, repair of these lesions, after drug removal, was rapid and similar in the parental and drug-resistant sublines, with 50% having resealed within 20-26 min. Resistance to etoposide was also associated with significantly elevated (p less than 0.01) glutathione peroxidase activity in both sublines, whilst glutathione S-transferase activity was marginally elevated (117%) only in the HN-I/DXR-II cells. There were no significant alterations in total glutathione levels. These results suggest that not only do patterns of response to anti-tumour drugs differ depending upon the agent employed to "induce" resistance, but that multiple mechanisms appear to be associated with these altered responses.
Unusual Regioselectivity of the Dipolar Cycloaddition Reactions of Nitrile Oxides and Tertiary Cinnamides and Crotonamides<sup>1</sup> (1998)

Benzonitrile oxides undergo 1,3-dipolar cycloaddition reactions with methyl cinnamate to produce the 5-phenyl and 4-phenyl regioisomers in approximately an 80:20 ratio. However, use of N,N-diethylcinnamide as the dipolarophile unexpectedly resulted in the formation of the 5-phenyl and 4-phenyl regioisomers in a 23:77 ratio. Studies have shown that this phenomena occurs only for tertiary cinnamides. In addition, it has been demonstrated that the phenyl group of tertiary cinnamides is not essential for the reversal of regioselectivity since crotonamides produce the same results and trends as the cinnamides. However, since acrylates and acrylamides both produce the 5-carbonyl regioisomers, it can be concluded that the beta-substituent is playing a key role for the unexpected results by possibly increasing steric interactions between the dipole and dipolarophile in the transition state. Transition state energies were calculated for the regioisomeric cycloadduct pairs derived from several crotonamides as well as methyl crotonate. These calculations indicate that steric factors are indeed responsible for the reversal of regioselectivity.
Enhanced adhesion of silica for epoxy molding compounds (EMCs) by plasma polymer coatings (2002)

Abstract Silica for epoxy molding compounds (EMCs) was coated via plasma polymerization using an RF plasma (13.56 MHz) as a function of the plasma power, gas pressure, and treatment time. The monomers utilized for the plasma polymer coatings were 1,3-diaminopropane, allylamine, pyrrole, 1,2-epoxy-5-hexene, allyl mercaptan, and allyl alcohol. The EMC samples were prepared from biphenyl epoxy resin, phenol novolac, triphenyl phosphine, and plasma polymer-coated silica, and the loading of silica was controlled to 60 wt%. The EMC samples were cured at 175°C for 4 h and subjected to Tg, CTE, and water absorption measurements. The adhesion of silica to epoxy resin was evaluated by measuring the flexural strength of EMC samples and the fracture surfaces were analyzed by SEM. Plasma polymer coatings were also characterized by FT-IR and coating thickness measurements. The plasma polymer coating of silica with 1,3-diaminopropane and allylamine enhanced the flexural strength of EMC samples (167 and 165 MPa), compared with the control sample (140 MPa), and exhibited a higher Tg, a lower CTE, and lower water absorption. The enhanced properties with 1,3-diaminopropane and allylamine plasma polymer coatings can be attributed to the amine functional groups in the plasma polymer coatings.

Removal of Cadmium, Lead, Mercury, Tin, Antimony, and Arsenic from Drinking and Seawaters by Colloid Precipitate Flotation (1995)

Abstract The removal of Cd(II), Pb(II), Hg(II), Sn(II), Sn(IV), Sb(III), Sb(V), As(III), and As(V) from aqueous solutions by colloid precipitate flotation using sodium sulfide as the coagulent and oleic acid (HOL) as the surfactant has been investigated. The complete flotation (about 100%) of these elements was attained at pH values of 5.5–6.5, 3–6.5, ≤1, 1–4, 0.5–3, and ≤2, respectively. The effects of some other factors, such as surfactant and coagulent concentrations, sequence of adding reagents, some selected foreign ions, ionic strength, and temperature, on the floatability of these elements have been studied. It was found that both temperature and ionic strength have no appreciable effect on the flotation efficiency of the metal ions investigated. The method was successfully applied to remove completely these metal ions added to 1 L samples of drinking and seawaters at the optimum conditions for each element. Moreover, the mechanism of flotation is proposed.
The influence of pH, temperature and hydrolyzate concentration on the removal of volatile and nonvolatile compounds from sugarcane bagasse hemicellulosic hydrolyzate treated with activated charcoal before or after vacuum evaporation (2001)

This paper analyzes the influence of pH, temperature and degree of hydrolyzate concentration on the removal of volatile and nonvolatile compounds from sugarcane bagasse hemicellulosic hydrolyzate treated with activated charcoal before or after the vacuum evaporation process. Furfural and 5-Hydroxymethylfurfural were almost totally removed in all the experiments, irrespective of pH and temperature and whether the charcoal was added before or after the vacuum evaporation process. Adding activated charcoal before the vacuum evaporation process favored the removal of phenolic compounds for all values of pH. Acetic acid, on the contrary, was most effectively removed when the activated charcoal was added after the vacuum evaporation process at an acid pH (0.92) and at the highest degree of hydrolyzate concentration (f=4). However, addition of activated charcoal before or after vacuum evaporation at an acid pH (0.92) and at the highest degree of hydrolyzate concentration (f=4) favored the removal of both acetic acid and phenolic compounds.
A survey of X protocol multiplexors (1993)

An X multiplexor allows a single X Window System client to be displayed and interacted with on several X servers simultaneously. Such a service is necessary for the construction of a computer-supported cooperative work (CSCW) environment such as JVTOS (Joint Viewing and Tele-Operation Service) which is being implemented within RACE II project CIO 1 . This paper describes several existing X multiplexors and evaluates their usefulness for JVTOS.
The TNO Gastro-Intestinal Model (TIM) (2015)

The TNO Gastro-Intestinal Model (TIM) is a multi-compartmental model, designed to realistically simulate conditions in the lumen of the gastro-intestinal tract. TIM is successfully used to study the gastro-intestinal behavior of a wide variety of feed, food and pharmaceutical products. Experiments in TIM are based on a computer simulation of the digestive conditions in the lumen of the gut during transit and digestion of a meal in vivo. These conditions include controlled parameters such as gastric and small intestinal transit, flow rates and composition of digestive fluids, pH values, and removal of water and metabolites. Simulation protocols have been developed for young, adult and elderly humans, dogs, pigs and calves after ingestion of various meals. The typical end point from results obtained with TIM is the availability of a compound for absorption through the gut wall (bio-accessibility). Results from TIM—with or without additional intestinal cell assays and in silico modeling—show a high predictability as compared to in vivo data (Marteau et al., J Dairy Sci 80:1031–1037, 1997; Verwei et al., J Nutr 136:3074–2078, 2006; Bellmann et al., TIM-carbo: a rapid, cost-efficient and reliable in vitro method for glycaemic response after carbohydrate ingestion.

Automated Prediction of the Apnea-Hypopnea Index from Nocturnal Oximetry Recordings (2011)

Nocturnal polysomnography (PSG) is the gold-standard for sleep apnea-hypopnea syndrome (SAHS) diagnosis. It provides the value of the apnea-hypopnea index (AHI), which is used to evaluate SAHS severity. However, PSG is costly, complex, and time-consuming. We present a novel approach for automatic estimation of the AHI from nocturnal oxygen saturation (SaO(2)) recordings and the results of an assessment study designed to characterize its performance. A set of 240 SaO(2) signals was available for the assessment study. The data were divided into training (96 signals) and test (144 signals) sets for model optimization and validation, respectively. Fourteen time-domain and frequency-domain features were used to quantify the effect of SAHS on SaO(2) recordings. Regression analysis was performed to estimate the functional relationship between the extracted features and the AHI. Multiple linear regression (MLR) and multilayer perceptron (MLP) neural networks were evaluated. The MLP algorithm achieved the highest performance with an intraclass correlation coefficient (ICC) of 0.91. The proposed MLP-based method could be used as an accurate and cost-effective procedure for SAHS diagnosis in the absence of PSG.
