Vehicle Ego-Motion Estimation and Moving Object Detection using a Monocular Camera (2006)

This paper proposes a method for estimating the ego-motion of the vehicle and for detecting moving objects on roads by using a vehicle mounted monocular camera. There are two problems in ego-motion estimation. Firstly, a typical road scene contains moving objects such as other vehicles. Secondly, roads display fewer feature points compared to the number associated with background structures. In our approach, ego-motion is estimated from the correspondences of feature points extracted from various regions other than those in which objects are moving. After estimating the ego-motion, the three dimensional structure of the scene is reconstructed and any moving objects are detected. In our experiments, it has been shown that the proposed method is able to detect moving objects such as vehicles and pedestrians
Recognition of chain-coded handwrittencharacter images with scanning <i>n</i> -tuplemethod (1995)

A method of applying n-tuple recognition techniques to handwritten OCR, which involves scanning an n-tuple classifier over a chain-code of the image, is described. The traditional advantages of n-tuple recognition, i.e. training and recognition speed, are retained, while offering superior recognition accuracy, as demonstrated by results on three widely used data sets.
Self-assembly of β-d glucose-stabilized Pt nanocrystals into nanowire-like structures (2005)

In this work we demonstrate the self-assembly of beta-D glucose-protected Pt nanocrystals (average particle size = 4.1 nm) into nanowire-like assemblies under ambient conditions.
Lazy XSL transformations (2003)

We introduce a lazy XSLT interpreter that provides random access to the transformation result. This allows efficient pipelining of transformation sequences. Nodes of the result tree are computed only upon initial access. As these computations have limited fan-in, sparse output coverage propagates backwards through the pipeline.In comparative measurements with traditional eager implementations, our approach is on par for complete coverage and excels as coverage becomes sparser. In contrast to eager evaluation, lazy evaluation also admits infinite intermediate results, thus extending the design space for transformation sequences.To demonstrate that lazy evaluation preserves the semantics of XSLT, we reduce XSLT to the lambda calculus via a functional language. While this is possible for all languages, most imperative languages cannot profit from the confluence of lambda as only one reduction applies at a time.
Stochastic simulation of laminar and electroosmotic convection in capillary electrophoresis and electrochromatography (2001)

A stochastic (Monte Carlo) simulation has been utilized to study the combination of laminar and electroosmotic convection under typical conditions for capillary electrophoresis and electrochromatography. The radial velocity profiles are determined for varying proportions of laminar and electroosmotic flow at a constant linear velocity. In addition, the molecular zone profiles and the corresponding statistical moments are established for nonretained and retained solutes. It is found that the radial velocity profile has significant influence for solutes that are not retained by a stationary phase, including those separated by electrophoresis alone. However, this effect is rapidly diminished such that retained solutes with an absorption coefficient as small as 0.1 show little influence if their diffusion coefficients in the mobile phase are on the order of 1.0 x 10(-5) cm2/s. Larger solutes with diffusion coefficients of 1.0 x 10(-6) cm2/s or less show slightly greater variance and asymmetry. In most cases, however, slow kinetics and resistance to mass transfer in the stationary phase exceed that in the mobile phase. As a consequence, there is little effect of the radial velocity profile for retained solutes.
Patterns and Practices of Women's Leadership in the Yorkshire Quaker Community, 1760-1820 (2006)

By the second half of the eighteenth century, women ministers had become the principal upholders of the spiritual life of Quakerism in Yorkshire. Drawing on a range of sources including the institutional records of Quaker Meetings, personal correspondence and spiritual journals and autobiographies, this paper aims to shed light on the precise nature of female leadership in the Religious Society of Friends and to contribute to greater understanding of the conditions under which it became dominant. It suggests that the growing tendency for women to outnumber men as ministers was closely linked to wider social and economic trends within contemporary Quakerism, and highlights the importance of family ties and support networks of kinship and friendship in underpinning women's exercise of ministering responsibilities.

A 50 GHz broad-band monolithic GaAs/AlAs resonant tunneling diode trigger circuit (1994)

This paper describes the design, circuit simulation, fabrication and testing of a 50 GHz trigger circuit using GaAs/AlAs resonant tunneling diodes. A new trigger circuit was designed to eliminate the 180/spl deg/ phase splitter used in a previous complementary input trigger circuit. Our monolithic approach, integrated GaAs/AlAs resonant tunneling diodes (in a back-to-back configuration) and a 50 /spl Omega/ coplanar waveguide, minimized the parasitic circuit elements and internal reflections from the package thus achieving high frequency operation. The circuit was able to trigger on input sinusoidal waves of input powers of -3 dBm up to 50 GHz with time jitter of less than 1 ps rms over the entire measured frequency range from 5 to 50 GHz. The upper limit of 50 GHz was imposed by our measurement system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Soluble amphiphilic tannin-stabilized Pd(0) nanoparticles: a highly active and selective homogeneous catalyst used in a biphasic catalytic system (2009)

Homogeneous BT-stabilized Pd(0) nanoparticles are highly active for the biphasic hydrogenation of hydrophobic substrates because BT is an amphiphilic polymer that can form hydrophobic bonds with the organic phase, thus increasing the possibility of catalytic species to contact with hydrophobic substrates.
Clinical Use of Neuromuscular Electrical Stimulation for Children With Cerebral Palsy, Part 1: Lower Extremity (1993)

This report, part 2 of a two-part case report on the clinical use of neuromuscular electrical stimulation (NMES) for children with cerebral palsy, documents the functional changes that occurred with the application of NMES to the upper extremity of two children, 1.6 and 6.7 years of age, with hemiplegia due to cerebral palsy. The NMES was used as an adjunct to a dynamic-systems, task-oriented physical therapy program. The youngest child showed immediate improvement in the ability to crawl and use both hands together. The older child demonstrated increased sensory awareness and use of the nonfunctional hand. Preliminary findings suggest that NMES may be a useful physical therapy tool for enhancing muscle strength increasing sensory awareness, and assisting motor learning and coordination.
Biologic markers and antidepressant response. (1983)

The use of biologic markers to predict antidepressant treatment response may lead to more rational selection of specific drugs for individual patients. Several biologic markers being developed as potential predictors of antidepressant treatment response are reviewed. Although research in this area is primarily concerned with predicting response to drug treatment, it may also prove useful in predicting which depressed patients may respond best to psychological treatments or combinations of biologic and psychologic treatments.
Semiconductor laser in the 21st century (2001)

The semiconductor laser has been taking an important role in optoelectronics and IT backbones and will be keeping its position for the coming at least 10 years. There would still be a lot of chances to meet really novel subjects in research and development, e.g. the coverage of full spectral ranges, temperature insensitive operation, ultra-high power capability, frequency control, large scale integration, and so on. In this paper, we like to discuss of the semiconductor laser for tomorrow based upon the experience of founding research of vertical cavity surface emitting laser.
Effect of extracellular pH on thermotolerance and recovery of hyperthermic damage in vitro. (1979)

The aim of the present study was to investigate the effect of varying extracellular pH on the recovery of hyperthermic damage and the development of thermotolerance in L1A2 cells following heating at 42°.

When two hyperthermic treatments of 1.5 hr at 42° each were separated, the cell survival increased and reached a maximum at the end of a 10-hr interval at 37° (recovery ratio, 12.8). The recovery of the capacity to accumulate sublethal damage as measured by the return of the extrapolation number was complete and occurred within the first 4 hr, while the additional increase in survival for a fractionation interval of 4 to 10 hr resulted from the development of thermotolerance evidenced by an increase in D . The D of the hyperthermic cell survival curve increased from 30 to 124 min, and at the end of a 24-hr interval D was 50 min.

If the cells were treated in a modified Krebs-Ringer-phosphate buffer instead of Eagle's basal medium at various pH's, no difference was found at pH 7.2. A decrease of the extracellular pH from 7.2 to 6.3 resulted in a decreased cell survival at 42°. This was due to a change in the shoulder of the cell survival curve (altered capacity to accumulate sublethal heat damage) reflected by decreased extrapolation numbers. However, there was no change in sensitivity. Fractionation of two equal heat treatments each of 1.5 hr indicated that survival was maximally enhanced at the end of a 10-hr interval both at pH 7.2 and at pH 6.5. However, at pH 6.5, this enhancement was reduced by approximately 55% compared to that at pH 7.2.

At pH 6.8 and 6.5, the development of thermotolerance was partially inhibited, and at the end of a 10-hr interval, the D 's were 94 and 72 min, respectively. Furthermore, thermotolerant cells were not sensitized at the lower pH. In contrast, lowering the pH to 6.5 either during the interval separating the heat treatments or during the interval as well as during the second heat treatment resulted in a reduced development of thermotolerance similar to that observed in cells treated at pH 6.5 for the entire treatment.

The above-mentioned data indicate that reducing the extracellular pH partially inhibits the development of thermotolerance, and it seemed that a low pH in the interval was particularly responsible for the observed inhibition of thermotolerance development. As pH in tumors seems to be lower than that of the surrounding normal tissue, the results in this study may indicate the use of fractionated hyperthermia as a way of increasing the therapeutic ratio.
Spectral corrections based on optical air mass (2003)

The measurement of the photovoltaic (PV) performance with respect to reference conditions requires measuring the performance with respect to a reference spectrum. Procedures were developed in the mid 1980s to correct measurements for errors relating to the spectral irradiance of the light source being different from the standard and the responsivity of the irradiance detector being different from the device under test. In principle, these procedures are exact, but require the measurement of the spectral irradiance of the light source and responsivity of the test device. This is problematic for most facilities that measure module performance. It has been suggested that a polynomial fit of the short-circuit current (I/sub sc/) measured under natural sunlight divided by the total broadband irradiance as a function of air mass provides an accurate spectral correction factor. The polynomial correction factor is normalized to unity at an absolute air mass of 1.5. The polynomial correction factor is compared with the spectral correction factor for a variety of devices at two locations.
Chemoenzymatic synthesis and biological evaluation of enantiomerically enriched 1-(β-hydroxypropyl)imidazolium- and triazolium-based ionic liquids (2013)

Racemic 1-(β-hydroxypropyl)azoles were prepared by solvent-free direct regioselective ring opening of 1,2-propylene oxide with imidazole or 1,2,4-triazole. Lipase-catalyzed transesterification of alcohols with vinyl acetate resulted in kinetic enantiomers resolution. Separated (S)-enantiomers of (+)-1-(1H-imidazol-1-yl)propan-2-ol and (+)-1-(1H-1,2,4-triazol-1-yl)propan-2-ol were quaternized with alkyl bromides or iodides, yielding novel optically active ionic liquids. Racemic salts were tested against a wide range of microorganisms.
Metagenomic sequencing of clinical samples reveals a single widespread clone of Lawsonia intracellularis responsible for porcine proliferative enteropathy (2020)

<i>Lawsonia intracellularis</i> is a Gram-negative obligate intracellular bacterium that is the aetiological agent of proliferative enteropathy (PE), a common intestinal disease of major economic importance in pigs and other animal species. To date, progress in understanding the biology of <i>L. intracellularis</i> for improved disease control has been hampered by the inability to culture the organism <i>in vitro</i>. In particular, our understanding of the genomic diversity and population structure of clinical <i>L. intercellularis</i> is very limited. Here, we utilized a metagenomic shotgun approach to directly sequence and assemble 21 <i>L</i>. <i>intracellularis</i> genomes from faecal and ileum samples of infected pigs and horses across three continents. Phylogenetic analysis revealed a genetically monomorphic clonal lineage responsible for infections in pigs, with distinct subtypes associated with infections in horses. The genome was highly conserved, with 94 % of genes shared by all isolates and a very small accessory genome made up of only 84 genes across all sequenced strains. In part, the accessory genome was represented by regions with a high density of SNPs, indicative of recombination events importing novel gene alleles. In summary, our analysis provides the first view of the population structure for <i>L. intracellularis</i>, revealing a single major lineage associated with disease of pigs. The limited diversity and broad geographical distribution suggest the recent emergence and clonal expansion of an important livestock pathogen.
Children as webmakers (2013)

In this short paper, we describe the design of a new web editor for beginners called openHTML and our initial evaluation with children aged 10 and 11 in an after-school web-building workshop. Drawing on data from verbally administered surveys and participant observation, we identified three kinds of engagement with the workshop tasks: a homework orientation, an artistic orientation, and a social orientation. We describe the kinds of scaffolding that the children needed to complete their web pages, the places where they struggled, and translate these observations into implications for the design of a web editor for children.
Semantic search over encrypted data (2013)

Searchable encryption is a promising primitive in the context of outsourced data storage and in particular cloud computing. Current constructions lack searching capabilities beyond exact search on keywords and are thus less efficient than plaintext algorithm that take into account the meaning and return results corresponding to semantically close keywords. We thus advocate for the need of semantic search over encrypted data. We study the state of the art in stemming algorithms and in searchable encryption and propose the first semantic symmetric searchable encryption constructions. This improvement over searchable encryption has similar security as the prior work of Curtmola et al. on symmetric searchable encryption.

Commensal bacteria trigger a full dendritic cell maturation program that promotes the expansion of non-Tr1 suppressor T cells (2008)

Dendritic cells (DCs) orchestrate the immune response establishing immunity versus tolerance. These two opposite functions may be dictated by DC maturation status with maturity linked to immunogenicity. DCs directly interact with trillions of noninvasive intestinal bacteria in vivo, a process that contributes to gut homeostasis. We here evaluated the maturation program elicited in human DCs by direct exposure to commensal-related bacteria (CB) in the absence of inflammatory signals. We showed that eight gram(+) and gram(-) CB strains up-regulated costimulatory molecule expression in DCs and provoked a chemokine receptor switch similar to that activated by gram(+) pathogens. CB strains may be classified into three groups according to DC cytokine release: high IL-12 and low IL-10; low IL-12 and high IL-10; and low IL-12 and IL-10. All CB-treated DCs produced IL-1beta and IL-6 and almost no TGF-beta. Yet, CB instructed DCs to convert naive CD4+ T cells into hyporesponsive T cells that secreted low or no IFN-gamma, IL-10, and IL-17 and instead, displayed suppressor function. These data demonstrate that phenotypic DC maturation combined to an appropriate cytokine profile is insufficient to warrant Th1, IL-10-secreting T regulatory Type 1 (Tr1), or Th17 polarization. We propose that commensal flora and as such, probiotics manipulate DCs by a yet-unidentified pathway to enforce gut tolerance.
Increase in Terminal Restriction Fragments of <i>Bacteroidetes</i> -Derived 16S rRNA Genes after Administration of Short-Chain Fructooligosaccharides (2006)

It is well known that short chain fructooligosaccharides (scFOS) modify intestinal microbiota in animals as well as in humans. Since most murine intestinal bacteria are still uncultured, it is difficult for a culturing method to detect changes in intestinal microbiota after scFOS administration in a mouse model. In this study, we sought markers of positive change in murine intestinal microbiota after scFOS administration using terminal restriction fragment length polymorphism (T-RFLP) analysis, which is a culture-independent method. The T-RFLP profiles showed that six terminal restriction fragments (T-RFs) were significantly increased after scFOS administration. Phylogenetic analysis of the 16S rRNA partial gene sequences of murine fecal bacteria suggested that four of six T-RFs that increased after scFOS administration were derived from the 16S rRNA genes of the class Bacteroidetes. Preliminary quantification of Bacteroidetes by real-time PCR suggests that the 16S rRNA genes derived from Bacteroidetes were increased by scFOS administration. Therefore, the T-RFs derived from Bacteroidetes are good markers of change of murine intestinal microbiota after scFOS administration.
New Analogues of (<i>E</i>)-β-Farnesene with Insecticidal Activity and Binding Affinity to Aphid Odorant-Binding Proteins (2011)

(E)-β-farnesene is a strong and efficient alarm pheromone in most aphid species. However, applications in agriculture are prevented by its relatively high volatility, its susceptibility to oxidation and its complex and expensive synthesis. To develop novel compounds for aphid control, we have designed and synthesized analogues of (E)-β-farnesene, containing a pyrazole moiety present in several insecticides. Their structures have been confirmed by 1H NMR, elemental analysis, high-resolution mass spectroscopy and IR. Binding activities to three odorant-binding proteins (OBPs) of the pea aphid Acythosiphon pisum have been evaluated and correlated with their structures with reference to (E)-β-farnesene. Several derivatives were shown both to bind to A. pisum OBPs with a specificity similar to that of (E)-β-farnesene and to have aphicidal activity comparable to that of thiacloprid, a commercial insecticide. The compounds synthesized in this work represent new potential agents for aphid population control and provide guidelines to design analogues of (E)-β-farnesene endowed with both insecticidal and repellent activity for aphids.
Dynamic system characterization of enterprise servers via nonparametric identification (2005)

Dynamic characterization and fault detection are carried out in enterprise servers using nonparametric identification techniques based on sinusoidal excitation. The introduction of subtle sinusoidal perturbations in computer load variables or physical variables allows us to obtain a dynamic input-output characterization in the frequency domain. The input-output relationship is described in terms of coupling coefficients between a wide variety of physical and performance variables at different selected frequencies. This innovative approach in the field of computer science, based on a well-known system identification technique, has been demonstrated in empirical studies to provide valuable dynamic system characterization information that can be indispensable to datacenter operations personnel for the functions of performance management, capacity planning, quality-of-service (QoS) assurance, dynamic resource provisioning, and root cause analyses.
Co-channel interference cancellation techniques for antenna array assisted multiuser OFDM systems (2000)

Minimum mean square error (MMSE)-based multiple-antenna assisted co-channel interference suppression/space division multiple access (SDMA) schemes designed for OFDM have drawn wide interest. In this article, parallel interference cancellation (PIC) is proposed and studied in comparison to maximum likelihood sequence estimation (MLSE) based schemes. The best design trade-off was constituted by the successive interference cancellation (SIC) schemes.

Syntheseversuche in der Emetinreihe 10. Mitteilung [1] Zur Oxydation von 2‐Dehydro‐emetin‐Verbindungen mit Quecksilber(II)‐acetat (1964)

Abstract Trisdehydro‐emetinium salts of type IVa were prepared from rac. 2‐Dehydroisoemetine (IIa) by oxidation with mercury(II)‐acetate. IVa was reduced with sodium borohydride to a mixture of rac. 2‐dehydro‐emetine (IIIa) and IIa. The same sequence of reactions was carried out with the N‐acetyl derivatives IIc, IVc and IIIc. Under basic conditions or on heating, IVa breaks down to V and VI.
