Collision-free motion of an articulated kinematic chain in a dynamic environment (1989)

A method for the collision avoidance of an articulated kinematic chain in a dynamic environment is presented. The inverse kinematic solution is used to get the configuration of the chain for a given position of any part of the chain. The calculation of collision-free motion is based on the local information about the motion. Intermediate positions are used to get the new motion path of the chain. The movement of environmental objects during the collision detection and the generation of new motions are considered. This generalizes the method for arbitrarily configured kinematic chains and for a dynamic environment. Its implementation for the motion planning of robot manipulators in an offline programming system is briefly described.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Using Spreadsheets to Learn Numerical Methods (2006)

The common spreadsheet is an excellent tool for students in a first course in numerical methods. It makes it easy to construct illustrative examples, to experiment with them, and to plot results in graphi-cal form. For the students in a class in numerical methods who are majoring in a subject other than computer science (e.g., physics, engineering, or economics, spreadsheets offer an attractive alternative to conventional programming that allows ready experimentation with numerical algorithms. All stu-dents, in fact, no matter what their major, seem to appreciate the immediate display of results that spreadsheets allow.
MODELED IMPACTS OF DEVELOPMENT TYPE ON RUNOFF VOLUME AND INFILTRATION PERFORMANCE<sup>1</sup> (2004)

ABSTRACT: Development type has emerged as an important focal point for addressing a wide range of social, cultural, and environmental concerns related to urban growth. Low impact development techniques that rely heavily on infiltration practices are increasingly being used to manage storm water. In this study, four development types (conventional curvilinear, urban cluster, coving, and new urbanism) were modeled both with and without infiltration practices to determine their relative effects on urban runoff. Modeling was performed with a modified version of the Natural Resources Conservation Service (NRCS) runoff method that enables evaluation of infiltration practices. Model results indicate that urban cluster developments produce the smallest volume of runoff due to the large portion of land kept in a natural condition. Infiltration practices are most effective for small storms and in developments with Hydrologic Group A soils. Significant reductions in runoff can be achieved in all four development types if infiltration practices treat many impervious surfaces. As more infiltration practices are implemented, the differences in runoff among development types diminish. With a strategic combination of site layout and infiltration design, any development type can reduce hydrologic impacts, allowing developers to consider other factors, such as convenience, marketability, community needs, and aesthetics.

RobustTAD: Robust Time Series Anomaly Detection via Decomposition and Convolutional Neural Networks (2020)

The monitoring and management of numerous and diverse time series data at Alibaba Group calls for an effective and scalable time series anomaly detection service. In this paper, we propose RobustTAD, a Robust Time series Anomaly Detection framework by integrating robust seasonal-trend decomposition and convolutional neural network for time series data. The seasonal-trend decomposition can effectively handle complicated patterns in time series, and meanwhile significantly simplifies the architecture of the neural network, which is an encoder-decoder architecture with skip connections. This architecture can effectively capture the multi-scale information from time series, which is very useful in anomaly detection. Due to the limited labeled data in time series anomaly detection, we systematically investigate data augmentation methods in both time and frequency domains. We also introduce label-based weight and value-based weight in the loss function by utilizing the unbalanced nature of the time series anomaly detection problem. Compared with the widely used forecasting-based anomaly detection algorithms, decomposition-based algorithms, traditional statistical algorithms, as well as recent neural network based algorithms, RobustTAD performs significantly better on public benchmark datasets. It is deployed as a public online service and widely adopted in different business scenarios at Alibaba Group.
Cross-Reactions between Tryptic Polypeptides of Staphylococcal Enterotoxins B and C (1979)

The strong cross-reactions demonstrated for staphylococcal enterotoxins B (SEB) and C1 (SEC1) by measurement of antigen-binding capacity were reflected in well defined polypeptides obtained by limited tryptic digestion from SEB and SEC1. Two antigenic determinants on each enterotoxin were capable of reacting with heterologous antibody, one on the first 57 amino acids and one on the last 150 residues of the polypeptide backbone. The larger, carboxyl terminal polypeptides bound efficiently to homologous antiserum but about two orders of magnitude less efficiently to heterologous antibody. The amino terminal peptides showed only weak homologous binding but nearly comparable heterologous binding. It is proposed that the determinant on the amino terminal polypeptides is largely responsible for the strong reciprocal binding of the intact enterotoxins and that their low antigen-binding capacity is due to a random or a structurally distorted conformation in solution.
The Wound Healing Action of Kakawati Gel from Gliricidia sepium (Jacques) Steudel (Family Fabaceae) (2015)

Objective: Gliricidia sepium, locally known as kakawati is recognized for its wound healing property. The study aimed to determine the wound healing action of a safe, stable, low cost formulation from the lyophilized sap of G sepium. Methods: The organoleptic, physical, and chemical properties were determined. Short term stability testing, as well as compatibility study with common excipients was performed. Wound healing property was determined by three methods: (1) measurement of the rate of wound contraction, (2) tensile strength of the healed tissue using a tensiometer and (3) histological examination of collagen deposition. The 7.5% gel formulation was also tested for its efficacy with wound healing-impaired rats.
Results: The pilot-scale manufacture of a gel-based formulation using water extract of G sepium was feasible. The extract was compatible with glycerin, sodium CMC, sodium
benzoate and sodium citrate. Stability testing with common excipients showed that the gel formulation was stable at a temperature of 30oC. It was stable at pH values of 5 to10 and in natural and artificial light. The formulated product is a green gel of moderate consistency possessing a natural fragrance with faint fetid odor. The gel formulation was found to be effective at 7.5% concentration as a wound healing agent.
Conclusion: The gel formulation has been proven to have wound healing properties and was found to be safe, effective, stable and low cost.
Cloning of the <i>rfb</i> gene cluster of a group C2 <i>Salmonella</i> strain: comparison with the <i>rfb</i> regions of groups B and D (1991)

We report the cloning and mapping of the entire rfb gene cluster of a group C2 Salmonella strain. Comparison with the rfb region of group B strain LT2 and group D strain Ty2 reveals an 11.8 kb central region of limited similarity flanked by regions of high similarity. The genes from the central region confer a group C2 O-antigen structure on a Salmonella LT2 partial delete strain. The significance of this region in relation to function and evolutionary origin is discussed. We also report evidence for the existence of an O-antigen chain-length determinant in Escherichia coli K12 and propose a model for a possible mechanism by which a preferred chain length is determined.

Radiographic measurement of bone mineral: reviewing dual energy x-ray absorptiometry. (1995)

Features of the three major brands of DEXA equipment available in Australasia have been summarised. Radiation hazard is small with patient effective doses of the order of a few microSieverts. In vivo measurement precision of the order of 1% is achievable for PA scans of the lumbar spine. Lateral scans can achieve measurement precision of the order of 4%. Recent technological developments using X-ray fan beams and multi element detector arrays on C-arm devices have resulted in faster scan times, higher resolution images, and an ability to perform PA and lateral scanning without the need to reposition the patient. Accuracy of DEXA is dependent upon specific instrumentation and data reduction algorithms, but results generally correlate well with ashed bone measurements. Major sources of inaccuracy include inhomogeneous distributions of fat, and machine specific factors such as edge detection algorithms. Lack of absolute inter unit comparability may cause difficulties in clinical practice.
Cloning and expression of the murine gene and chromosomal location of the human gene encoding <i>N</i>-acetylglucosaminyltransferase I (1992)

A mouse cDNA clone previously isolated from an F9 teratocarcinoma cell library and shown to confer N-acetylglucosaminyltransferase I (GlcNAc-TI) activity on Lec1 Chinese hamster ovary (CHO) cell transfectants [Kumar, R., Yang,J., Larsen,R.D. and Stanley,P. (1990) Proc. Natl. Acad Sci. USA, 87, 9948-9952] has been sequenced. The nucleotide and deduced amino acid sequences are highly homologous to previously described human and rabbit GlcNAc-TI cDNAs. A 1250 bp portion of the mouse cDNA encoding all but the first 34 amino acids of the deduced protein sequence was inducibly expressed in Escherichia coli and gave rise to a prominent fusion protein of mol. wt approximately 45 kDa whose presence correlated with high levels of GlcNAc-TI activity in cell lysates. Probes generated from the cDNA were used to show that the GlcNAc-TI gene is present in a single copy in mammals and that a homologous gene was not detectable (under low-stringency hybridization conditions) in DNA from yeast, sea urchin, Drosophila or Chaenorhaditis elegans. Genomic DNA clones that hybridized to probes generated from the GlcNAc-TI cDNA were isolated from a mouse liver library. Restriction analyses, Southern hybridization and DNA sequence analyses of subcloned genomic DNA fragments and a polymerase chain reaction (PCR) product provided evidence that the coding and 3' untranslated regions of the cDNA reside in a single exon. However, the mouse GlcNAc-TI gene (Mgat-1) includes at least one additional exon 5' of the coding region. Southern analyses of DNA from mouse-human somatic cell hybrids and in situ hybridization were used to locate the human GlcNAc-TI gene (MGAT-1) between positions q31.2 and q31.3 on chromosome 5, a region of chromosome 5 that is syntenic with a region of mouse chromosome 11. Northern analyses of adult mouse tissues revealed two GlcNAc-TI gene transcripts that are differentially expressed in different tissues.
Fast calculation of the number of minimum-weight words of CRC codes (2001)

We investigate the most important parameter of the function of undetected error probability for shortened binary cyclic codes. This parameter is A/sub d/, the number of minimum-weight words. A fast method for calculation of A/sub d/ is presented. Our approach does not require calculation of the distance distribution of dual codes as most of the known methods do.
Internet connected FPGAs (2002)

There is a growing demand for small, low cost, low power, and flexible computing devices or appliances that attach directly to the Internet. For example, there are forecasts that non-PC devices will account for almost 50 percent of Internet devices by 2002 and that sales of such appliances will likely exceed the number of PCs sold by 2005. In this paper, we describe a platform that connects an FPGA directly to any Internet. We built this platform to investigate hardware and software implementations of an increasingly important function: Internet connectivity. The platform hardware consists of an FPGA; an interface device; storage for static and dynamic configuration; and nonvolatile configuration logic. Our design allows us to eliminate the need for a microprocessor and operating system.
Lymphocyte:Monocyte Ratio At The Start Of Conditioning Regimen Is Associated With Survival Post-Autologous Stem Cell Transplantation (ASCT) For Lymphoma and Myeloma (2013)

Abstract Introduction Several studies have suggested that an increased peripheral blood absolute lymphocyte count (ALC) at day 15 after ASCT is associated with improved survival and decreased relapse rate. Recently, the ratio of ALC to the absolute monocyte count (AMC) (Lymphocyte:Monocyte Ratio; LMR) has been described as a strong prognostic factor at time of diagnosis in patients with various lymphoid malignancies. In most reports, a LMR cut-off value of less than 1.1 indicates patients who have a worse outcome. Objective To evaluate the prognostic impact of the LMR at start of conditioning regimen and at day 15 post ASCT in patients with a diagnosis of lymphoma and myeloma Methods We retrospectively reviewed the medical records of 121 adult patients with a diagnosis of lymphoma or myeloma who underwent ASCT at Hospital Israelita Albert Einstein from January, 2005 to July, 2012. Lymphocyte count was registered at the 15th day after SCT and lymphopenia was defined as an ALC< 500 at this time point. The LMR was calculated considering the ALC and AMC at baseline (start of conditioning regimen) and at day 15 post-ASCT. Overall survival (OS) was estimated from the time of transplant until death, with surviving patients censored at last follow-up. Variables entered into the multivariate Cox analysis were those with a p-value <0.10 in the univariate analysis. Statistical analysis was performed with STATA (v11.0) and alfa error was defined as 5%. Results The majority of patients were male (69%) and the median age was 58 years old (range: 3–76). Peripheral stem cell harvest was the main source of cells (61%). Diagnosis included multiple myeloma (49%), non-Hodgkin’s lymphoma (45%) and Hodgkin’s lymphoma (6%). The median LMR at start of conditioning regimen was 0.60, while at day 15 it was 1.75. Seventy-three percent of patients at start of conditioning had a LMR <1.1, while the same percentage at day 15 was 25%. Considering LMR cut-off at 1.1, an increased LMR value at baseline was associated with improved survival (HR 0.44; p=0.03), while it was not predictive at day 15 (HR=0.99; p=0.99). At 2 years, the OS was 48% for patients with a LMR<1.1 at start of conditioning regimen versus 76% for those patients with a LMR ≥1.1 (p=0.03 by logrank). In a multivariate Cox analysis considering age, sex, diagnosis, day 15 lymphopenia and baseline LMR, baseline LMR remained an independent variable associated with survival (HR=0.40, p=0.044), while day15 lymphopenia had no prognostic value (HR=0.80. p=0.56). Conclusion In our cohort of patients, the presence of an increased LMR at baseline before start of conditioning regimen identified a subgroup of patients who had a very good outcome. These results should be validated in other cohorts. Strategies to improve outcome for patients who present with decreased LMR and a better understanding of the role of LMR should be the focus of future studies.

Comparative Analysis of Varios Diversity Techniques for Ofdm Systems (2013)

In this paper, three transmit diversity techniques are proposed that use extra transmit antennas to obtain additional diversity. An analytical expression for the signal-to-noise ratio (SNR) and bit-error-rate at the output of a three-branch maximal ratio combining, equal gain combining and selection diversity system is given. The three branches are assumed to be Rayleigh fading, correlated with the BPSK modulation. Measurements of the signal-to-noise ratio and bit-error-rate after selection, equal gain combining and maximal ratio combining were made in Rayleigh fading channels and compared with the analytical results. Also presented are the exact analytical average probabilities of bit error for coherent binary phase-shift keying for three-branch maximal ratio combining, equal gain combining and selective diversity for Rayleigh fading channel. All these three branches is compared on the basis of signal to noise ratio and bit error rate with the increasing no. of receiver. This work confirms the benefits of choosing the maximal ratio combining instead of equal gain combining and selection diversity by measuring the performances of these three branches for SNR and BER.
Characterization of the catalase antioxidant defense gene <i>Cat1</i> of maize, and its developmentally regulated expression in transgenic tobacco (1993)

A genomic clone containing the maize Cat1 gene has been isolated and its complete DNA sequence determined. The start of transcription has been mapped by primer extension. Six introns were identified in the Cat1 coding region. In order to determine the tissue-specific expression pattern of the Cat1 gene, promoter-reporter gene fusion constructs were made consisting of 2.5 kb and 0.8 kb of the 5' Cat1 sequence fused to the coding region of the beta-glucuronidase (GUS) gene. These fusion constructs were introduced into Nicotiana tabacum cv. Burley 21 and the expression of Cat1-GUS in various tissues was examined. In transgenic tobacco, the Cat1 promoter can drive GUS expression at relatively high levels in mature seeds. GUS activity starts to accumulate at about 10 days after flowering, reaching a maximum at about 22 days after flowering, and decreases thereafter, but persists until after seed desiccation through early germination. Low levels of GUS activity can be detected in pollen. This corresponds to the Cat1 expression pattern observed in maize.
Treatment Guidelines for Alzheimer's Disease (2007)

The expanding literature on AD medications suggests that treatment guidelines need to be reexamined. Recent data emphasize preservation of abilities and delay of adverse outcomes in AD patients rather than short-term improvements in cognitive test scores. Treatment appears to provide the greatest benefit when it is initiated early in the course of the disease and maintained over the long term. Revised treatment guidelines should address newer medications and more recent outcomes considerations, as well as provide guidance on how long to continue and when to discontinue pharmacotherapy for AD.
Cell Separation (2005)

Various physical methods for separating different cell types are discussed from simple low technology methods, like density centrifugation, to high technology methods, like centrifugal elutriation and fluorescence-activated cell sorting (FACS). Particular emphasis is given to magnetic sorting, which is highly effective but not dependent on major capital investment. Protocols are provided for both density centrifugation and magnetic sorting (MACS). Cloning and selective media are dealt with in Chapter 14.
Intrinsic regulation of substrate fluxes and energy conservation in Ca<sup>2+</sup>‐ATPase (1985)

The Ca2+-ATPase of sarcoplasmic reticulum was utilized to demonstrate an intrinsic regulation of enzyme catalysis, whereby the ratio of forward and reverse flow is altered by the binding of Ca2+ and Pi to the enzyme. This is related to displacement of internal equilibria among intermediate enzyme ligand complexes, independent of the overall equilibrium of the ATP in equilibrium ADP + Pi transformation. A very high energy conservation with a velocity of reverse flow approaching that of forward flow, was obtained by increasing the enzyme affinity for Pi in the presence of Me2SO.
