Trajectory generation for an on-road autonomous vehicle (2006)

We describe an algorithm that generates a smooth trajectory (position, velocity, and acceleration at uniformly sampled instants of time) for a car-like vehicle autonomously navigating within the constraints of lanes in a road. The technique models both vehicle paths and lane segments as straight line segments and circular arcs for mathematical simplicity and elegance, which we contrast with cubic spline approaches. We develop the path in an idealized space, warp the path into real space and compute path length, generate a one-dimensional trajectory along the path length that achieves target speeds and positions, and finally, warp, translate, and rotate the one-dimensional trajectory points onto the path in real space. The algorithm moves a vehicle in lane safely and efficiently within speed and acceleration maximums. The algorithm functions in the context of other autonomous driving functions within a carefully designed vehicle control hierarchy.

Calculation and Analysis of Sensitivity Field for Multiphase Flow Electromagnetic Tomography (EMT) In Well Logging (2003)

Abstract Using a numerical method, we calculate the sensitivity field, which is of great importance for the optimal design of the multiphase flow Electromagnetic Tomography (EMT) tools and image reconstruction in well logging computation in this paper. For the facility of analysis, the calculation is performed in 2 planes based on the symmetry of the sensor, though the sensitivity field is 3 dimensional. The analysis contains 2 connected steps. First, the potential distribution within the measure array is calculated using FEM (Finite Element Method). Secondly, the gradient of the potential is acquired according to the numerical computation. The result shows that the sensitivity field appears an arc‐shape within the region from the transmitting electrode to the measuring electrode, and it can be expressed approximately using an exponential function.
RESEARCH ARTICLE Building A Privacy-Preserving Benchmarking Enterprise System (2008)

Benchmarking is the process of comparing one’s own performance to the statistics of a group of competitors, named peer group. It is a common and important process in the business world for many important business metrics, called key performance indicators (KPI). Privacy is of the utmost importance, since these KPIs allow the inference of sensitive information. Therefore several secure multi-party computation (SMC) protocols for securely and privately computing statistics of KPIs have recently been developed. These protocols are the basic building block for a privacy-preserving benchmarking system, but in order to complete an enterprise system that offers a benchmarking service to its customers more problems need to be solved. This paper addresses two remaining problems: peer group formation and protocol orchestration. We first analyze how peer group participation impacts privacy and vice-versa. Given current network performance limitations we conclude that in order for KPIs to remain private one subscriber can participate in at most one peer group. Peer group formation is the process of forming sensible peer groups out of the set of subscribers. A sensible peer group is one that is useful for benchmarking, i.e. a group of
Effect of pyruvate kinase deficiency on L-lysine productivities of mutants with feedback-resistant aspartokinases. (1987)

The cultural conditions were investigated for a Brevibacteriumflavum mutant, No. 2-190, with a low level of citrate synthase (CS) and with feedback-resistant phosphoenoipyruvate (PEP) carboxylase and aspartokinase (AK). The productivity was increased from 28 to 38 g/l (as the HCl salt) with a medium containing 10% glucose. From this strain, pyruvate kinase (PK)-defective mutants were derived and selected as to the inability to grow on ribose. Among them, strain KL-18 showed higher lysine productivity than the parent under all cultural conditions tested, and produced 43 g/l of lysine, at maximum. A lysine-producing mutant, No. 536-4, with a feedback-resistant AK was derived from PK-defective strain KH-21 which had low CS activity and a feedback-resistant PEP carboxylase. The mutant was isolated by a new selection method, that is, on the basis of resistance to α-amino-β-hydroxyvaleric acid, a threonine analogue plus lysine. In this strain, HD had been altered so as to become feedback-resistant at the same time, resulting in the byproduction of threonine and isoleucine. The total amount of these aspartate family amino acids was higher on molar basis than that of lysine produced by strain No. 2-190.
Compound 3-D visualization of reconstructed coronary arteries, left ventricle and aorta from biplane X-ray angiograms (2003)

The authors describe 3-D reconstruction and display techniques to integrate various parts of the heart, such as the coronary arteries, the left ventricle, and the aorta in the same 3-D image space. 3-D shapes of the coronary arteries were reconstructed by using the arterial boundaries on biplane angiograms detected almost automatically. The 3-D shapes of the left ventricle and the aorta were also reconstructed, and these 3-D images of parts of the heart were displayed in the same 2-D image plane, which provides very useful visual information on the structure of the anatomy for coronary arteries. The original data used were conventional images from two sets of biplane X-ray angiography: left ventricular and coronary angiograms recorded on a videotape. The authors used commonly imaged parts on both angiograms such as the spine and the catheter to match the scaling and mutual position of organs on the two angiograms.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Short-term travel time prediction by deep learning: A comparison of different LSTM-DNN models (2017)

Predicting short-term travel time with considerable accuracy and reliability is critically important for advanced traffic management and route planning in Intelligent Transportation Systems (ITS). Short-term travel time prediction uses real travel time values within a sliding time window to predict travel time one or several time step(s) in future. However, the nonstationary properties and abrupt changes of travel time series make challenges in obtaining accurate and reliable predictions. Recent achievements of deep learning approaches in classification and regression shed a light on innovations of time series prediction. This study establishes a series of long short-term memory neural networks with deep neural layers (LSTM-DNN) using 16 settings of hyperparameters and investigates their performance on a 90-day travel time dataset from Caltrans Performance Measurement System (PeMS). Then competitive LSTM-DNN models are tested along with linear models such as linear regression, Ridge and Lasso regression, ARIMA and DNN models under 10 sets of sliding windows and predicting horizons via the same dataset. The results demonstrate the advantage of LSTM-DNN models while showing different characteristics of these deep learning models with different settings of hyperparameters, providing insights for optimizing the structures.
Genetic Analysis of the Maltose A Region in <i>Escherichia coli</i> (1969)

The genetic map of the maltose A locus of Escherichia coli contains at least three closely linked genes, malT, malP, and malQ. The order of these genes is established by deletion mapping. MalP and malQ, the presumed structural genes for maltodextrin phosphorylase and amylomaltase, belong to the same operon. MalT may be a regulator gene involved in the positive control of this operon.
Application of the NMR method to evaluate the oxidative deterioration of crude and stored fish oils. (1990)

In a previous paper,l) we described the possibility for estimating the oxidative deterioration of fish oils by measuring the nuclear magnetic resonance (NMR). However, the validity of the estimation was only proved for two kinds of purified fish oil, which were neutral lipids extracted from sardine and pollack, and their methyl esters. In this paper, a general and practical application of this NMRmethod to several kinds of crude fish oil is reported. The total lipids obtained from sardine, saury, and

<p class="HeadingRunIn"><strong>Structure and morphological types of the antennal olfactory sensilla in Phryganeidae and Limnephilidae (Insecta: Trichoptera)</strong></p> (2011)

Structure of the antennal segments and ultrastructure of the sensilla in representatives of Phryganeidae and Limnephilidae have been investigated using scanning electronic microscopy (SEM) and optical microscopy. Twelve types of antennal sensilla have been observed and their preliminary classification based on cuticular structures is discussed. All types of sensilla are unevenly distributed on the surface of the antennal flagellum. The most characteristic feature is the presence of specialized sensory fields on the antennal segments (flagellomeres). These are the depressed ventral areas in the apical parts of flagellomeres in all Phryganeidae and Dicosmoecinae (Limnephilidae) and the elongate ventrolateral areas in more advanced Limnephilidae from the subfamilies Stenophylacinae and Limnephilinae. In contrast to the lower Dicosmoecinae with a wide variety of pseudoplacoid sensilla, the antennal surfaces of both sexes in the subfamilies Limnephilinae and Stenophylacinae have only specialized, dentate, small pseudoplacoids. These data suggest internal heterogeneity in the family Limnephilidae, where Dicosmoecinae have very different antennal structures, and support an hypothesis of separate status for Dicosmoecinae. The families Phryganeidae, Plectrotarsidae and Goeridae have only the forked sensilla while Apataniidae and Brachycentridae only mushroom-like pseudoplacoids. Comparison to representatives of Rhyacophilidae, Molannidae, Hydropsychidae, and Leptoceridae indicates that there are significant variations in the sensory structures of Trichoptera antennae. Functional aspects of the antennal structures in relation to the behavior interaction with the air currents are discussed.
Skin ageing: clinical and histopathologic study of permanent and reducible wrinkles. (2002)

Wrinkles are modifications of the skin associated with cutaneous ageing and develop preferentially on sun-exposed skin. The aim of the study was to analyse the clinicopathological features of wrinkles, among the different types of skin relief modifications. Despite its importance in dermato-cosmetology and skin ageing, few studies have been specifically devoted to wrinkles. In the present study, we analyzed the histological features of the pre-auricular wrinkle compared to retro-auricular skin, obtained from sixteen patients undergoing facial surgery; skin samples were immediately processed for routine histology and histochemical staining. Four types of skin depressions could be defined according to their depth: folds, permanent wrinkles, reducible wrinkles and skin micro-relief. Two different types of pre-auricular wrinkles were observed: (i) permanent wrinkles which were conserved after sampling and, (ii) reducible wrinkles which required in vivo staining to be visible at histology. Histological analysis of the epidermis and dermis of the skin forming the pre-auricular wrinkle revealed a normal skin morphology, identical to that of the skin immediately adjacent to the wrinkle. This was particularly striking for the reducible wrinkles which could not be individualized in the absence of in vivo staining. Both types of wrinkles comprised skin modifications observed in sun-exposed skin, however, in the upper dermis, permanent wrinkles showed a more pronounced accumulation of basophilic fibers, i.e. actinic elastosis, than reducible wrinkles did. These data suggest that the development of wrinkles could be secondary to actinic elastosis and to the disappearance of microfibrils and collagen fibers at the dermal-epidermal junction.
Pluronic polyol: A potential alloplastic keratorefractive material (1988)

Pluronic polyol possesses a negative temperature coefficient of gelation; it is liquid at low temperatures and gelatinous at high temperatures. Pluronic F108 was evaluated as a potential material for alloplastic keratorefractive surgery: 0.3 ml of the material in a liquid state was injected into a surgically prepared axial 7 mm mid-stromal corneal bed in 17 rabbits; fellow eyes in the rabbits were sham-operated but not injected. Postoperatively, rabbits were clinically evaluated with biomicroscopy, keratometry, and pachymetry at regular intervals up to three months following surgery. Animals were periodically sacrificed and corneas were studied by light and electron microscopy. The material appeared to be well tolerated by the cornea. Both control and pluronic eyes showed an initial increase in corneal thickness peaking at one week postoperatively, with return to near normal levels by the end of the third week. Refractive flattening of approximately three diopters was noted in the experimental group, while no change was seen in the control group.
Driven Magnetic Particles on a Fluid Surface: Pattern Assisted Surface Flows (2007)

Magnetic microparticles suspended on the liquid-air interface and subjected to an alternating magnetic field exhibit spontaneous formation of dynamic localized snake patterns. These patterns are accompanied by four large-scale hydrodynamic vortices located at the opposite ends of the snake patterns. We report detailed studies of these large-scale vortices and their relationship to the collective response of magnetic particles in the presence of an alternating magnetic field. We present a model based on the amplitude equation for surface waves coupled to the large-scale hydrodynamic mean flow equation. The model describes both the formation of the dynamic snake patterns and the induced structure of the experimentally observed hydrodynamic flows.
Possibilities of scar treatment after thoracic surgery. (1995)

During a ten year observation period it was found that scar formation after thoracic surgery is influenced by various factors: metabolism, operative technique and factors of a general nature. On the basis of these findings, a study was carried out to investigate the effect of the scar-specific Contractubex gel (Merz+Co., D-Frankfurt/Main), containing 10% onion extract, 50 U sodium heparin per g of gel and 1% allantoin, in the treatment of children who underwent thoracic surgery and to evaluate its effect on scar development. Before and during the six-month treatment period, both macromorphology and scar colour were assessed; furthermore, a global evaluation of the therapeutic result was made. Additionally, the scars were characterized after a six-month treatment-free follow-up period. The results of 38 Contractubex-treated and 27 untreated patients were compared. In the treated scars, the global evaluation of the therapeutic result was better than in the untreated scars. In the Contractubex group, the rating was "good" and "very good" in 84% of cases, as compared to 59% of the untreated cases. In the treated group, the increase in scar size was markedly lower than in the untreated patients. The treated scars showed a tendency towards quicker paling than the untreated scars. In the treated group, the conversion of primary physiological scars to unphysiological scars (hypertrophic or keloidal scars) was less frequent than in the untreated group. The tolerability of the product was very good in 37 of the 38 treated patients, and good in one patient. All scar-specific effects of Contractubex continued to persist after the end of treatment.
On differential transformations between Cartesian and curvilinear (geodetic) coordinates (1976)

Differential transformations are developed between Cartesian and curvilinear orthogonal coordinates. Only matrix algebra is used for the presentation of the basic concepts. After defining the reference systems used the rotation (R), metric (H), and Jacobian (J) matrices of the transformations between cartesian and curvilinear coordinate systems are introduced. A value of R as a function of H and J is presented. Likewise an analytical expression for J(-1) as a function of H(-2) and R is obtained. Emphasis is placed on showing that differential equations are equivalent to conventional similarity transformations. Scaling methods are discussed along with ellipsoidal coordinates. Differential transformations between elipsoidal and geodetic coordinates are established.
Transcriptionally active DNA region that rearranges frequently in murine lymphoid tumors. (1982)

A DNA region not associated with conventional immunoglobulin gene rearrangement is rearranged in many lymphoid tumors. This region, designated here as lymphoid rearranging (LyR) DNA, was cloned from plasmacytoma J558 in which it had recombined 5' to a constant (C) region of the alpha heavy (H) chain gene, C alpha, within a switch (S) region, S alpha, involved in the switching of CH genes. Sequence determination established that LyR DNA had recombined within a S alpha recombination unit. LyR DNA does not originate from the H chain locus, and discordance between LyR DNA and CH copy number in certain lines suggests that LyR DNA probably derives from another chromosome. LyR DNA rearrangement is a characteristic of tumors of mature B cells; it was detected in 24 of 28 plasmacytomas and B-cell lymphomas, usually as LyR-S alpha, but not in 11 Abelson retrovirus-induced lymphomas of B-cell precursors nor detectably in normal B cells. In contrast, rearrangement was observed in only 3 of 18 T-cell lymphomas, and none of seven nonlymphoid lines. Most tumor lines (49 of 52), whether lymphoid or not, contained a low level of polyadenylylated LyR transcript(s), but several new RNA species with differences in their 5' regions appeared in B-cell lines in which LyR DNA was rearranged, suggesting that rearrangement may activate a new promoter or mode of splicing. The results suggest that the LyR-S alpha rearrangement represents a translocation to chromosome 12 that alters expression of LyR-encoded genes; hence, it may have participated in lymphoid tumor oncogenesis.
Efficiently Editing the Vaccinia Virus Genome by Using the CRISPR-Cas9 System (2015)

Vaccinia virus (VACV) continues to be used in immunotherapy for the prevention of infectious diseases and treatment of cancer since its use for the eradication of smallpox. However, the current method of editing the VACV genome is not efficient. Here, we demonstrate that the CRISPR-Cas9 system can be used to edit the VACV genome rapidly and efficiently. Additionally, a set of 8,964 computationally designed unique guide RNAs (gRNAs) targeting all VACV genes will be valuable for the study of VACV gene functions.
Towards a Reinforcement Learning-based Exploratory Search for Mashup Tag Recommendation (2021)

The rapid increase in the number of online mashups requires better management and organization to facilitate mashup discovery, selection and recommendation. Tagging is one of the widely known and efficient ways to better manage and organize web services. Existing tagging methods are typically manual and tedious processes. On the other hand, current automatic tagging methods are either not very effective in describing their associated mashups or omit vital keywords that would enrich the set of candidates for tag selection. This paper presents a reinforcement learning (RL) method to automatically recommend tags for mashups. Our proposed method carries out effective exploratory actions to automatically extract suitable combinations of tags for mashups, through word vector similarities. Using our proposed method in a RL setup, we carry out experiments in an online mashup platform and evaluate our method with a real-world dataset from ProgrammableWeb <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> .
