Segmentation of speech into syllabic units (1974)

An algorithm has been designed to detect boundaries between syllabic segments of the speech signal, segments that contain but one peak or syllabic phoneme. A loudness function is defined, roughly corresponding to the short-time signal energy, and this function exhibits alternating sequence of points of relatively major maxima and minima. No absolute energy criteria appear adequate to decide whether a given maximum in the function is in fact a syllabic peak. However, minima can be characterized as significant with reference to the magnitudes of neighboring maxima. The algorithm uses the difference between the magnitude of the convex hull of the loudness function and the function itself as a measure of significance and recursively subsegments to the total signal until a given threshold of difference is nowhere exceeded. The algorithm is used as the first stage of a sequential procedure for segmentation and phonetic labeling of speech for recognition applications.

Colostomy plug devices (1992)

The authors report their experience in the use of the Conseal (Coloplast S.p.A., Bologna, Italy) Colostomy Plug, a new device for the regulation of continence in patients with colostomies. The devices were tested on 57 patients divided into two groups: Group A (36 patients) fit with a two-piece Conseal system and Group B (21 patients) fit with a one-piece Conseal system. All patients had the same colostomy type, and all were trained for self-irrigation. The objectives of this randomized, prospective study were to determine compliance with the different systems, to identify the advantages, and to verify the possible different applications among the population of irrigated patients. The following results were obtained. Regarding compliance: Group A's results were excellent in 22.2 percent and good in 52.7 percent of patients. Group B had better compliance than Group A (excellent in 66.6 percent and good in 19 percent of patients). Regarding controlled evacuation, continence time, and silent gas emission: in Group A, the device permitted controlled evacuations (23.8 percent of patients practicing daily washouts) with silent and odorless gas emission (100 percent of cases). In Group B, the results concerning improvement in continence were good (33.3 percent of patients) and excellent concerning the emission of flatus. Regarding the potential use of both systems in different groups of self-irrigated patients: the study has revealed the Conseal Uni-system as being ideal for patients with a well-constructed stoma, slight gas distention, and a better psychologic adaptability to larger-sized systems. In all other cases, the alternative two-piece system is more suitable, owing to the better safety it offers.

Bacterial ice nucleation: significance and molecular basis (1993)

Several bacterial species are able to catalyze ice formation at temperatures as warm as -2 degrees C. These microorganisms efficiently catalyze ice formation at temperatures much higher than most organic or inorganic substances. Because of their ubiquity on the surfaces of frost-sensitive plants, they are responsible for initiating ice formation, which results in frost injury. The high temperature of ice catalysis conferred by bacterial ice nuclei makes them useful in ice nucleation-limited processes such as artificial snow production, the freezing of some food products, and possibly in future whether modification schemes. The rarity of other ice nuclei active at high subfreezing temperature, and the ease and sensitivity with which ice nuclei can be quantified, have made the use of a promoterless bacterial ice nucleation gene valuable as a reporter of transcription. Target genes to which this promoter is fused can be used in cells in natural habitats. Warm-temperature ice nucleation sites have also been extensively studied at a molecular level. Nucleation sites active at high temperatures (above -5 degrees C) are probably composed of bacterial ice nucleation protein molecules that form functionally aligned aggregates. Models of ice nucleation proteins predict that they form a planar array of hydrogen binding groups that closely complement that of an ice crystal face. Moreover, interdigitation of these molecules may produce a large contiguous template for ice formation.
HIGH THROUGHPUT PHENOTYPING OF PHYSIOLOGICAL GROWTH DYNAMICS FROM UAS-BASED 3D MODELING IN SOYBEAN (2019)

Abstract. Nowadays, an essential tool to improve the efficiency of crop genetics is automated, precise and cost-effective phenotyping of the plants. The aim of this study is to generate a methodology for high throughput phenotyping the physiological growth dynamics of soybeans by UAS-based 3D modelling. During the 2018 growing season, a soybean experiment was performed at the Agronomy Center for Research and Education (ACRE) in West-Lafayette (Indiana, USA). Periodic images were acquired by G9X Canon compact digital camera on board senseFly eBee. The study area is reconstructed in 3D by Image-based modelling. Algorithms and techniques were combined to analyse growth dynamics of the crop via height variations and to quantify biomass. Results provide practical information for the selection of phenotypes for breeding.
On-Line Control in Wood and Paper Industries by means of Rapid Microwave Linear Sensors (1992)

This paper has two main-purposes. First of all, it presents recent technological developments of microwave linear sensors based on the Modulated Scattering Technique (MST). Secondly, it reports results of in-situ assessments conducted with such sensors on wood and paper materials. As a conclusion, the impact of the availability of such microwave multipoint sensors is analysed.
Complete amino acid sequence of chicken cartilage link protein deduced from cDNA clones. (1986)

cDNA clones coding for chicken cartilage link protein were isolated and sequenced. The DNA sequence for the entire core polypeptide of the mature link protein and the predicted signal peptide consists of 1065 nucleotides. The deduced primary translation product (355 amino acids) has a molecular mass of 40.7 kDa; the calculated molecular mass of the mature link protein core polypeptide (340 amino acids) is 39.06 kDa. The DNA sequence contains two tandemly arranged repeat sequences that may code for repeated functional domains of link protein involved in binding to hyaluronic acid. The mRNAs for chicken link protein are 6.0, 5.8, and 3.0 kilobase pairs, and the difference between the sizes of the RNA species lies in the 3' untranslated region.
μ-Opioid Agonists Stimulate Growth Hormone Secretion in Immature Rats (1996)

The purpose of the present study was to evaluate the opioid receptor subtype mediating opioid modulation of growth hormone (GH) secretion during ontogeny. The mu-agonist morphine and the kappa agonist U50,488 caused a stimulation and inhibition of GH secretion, respectively, on postnatal day 10. Studies on postnatal days 2, 5, 10, 15 and 20 showed that kappa-inhibition could be observed as early as day 2, but substantial mu-stimulation was not observed until postnatal day 10. Intracerebroventricular (i.c.v.) administration of the mu-selective peptide [D-Ala2-NMe-Phe4-Gly-ol]-enkephalin (DAMGO) elicited a marked rise in GH secretion, while administration of the delta-agonists [D-pen2D-pen5]-enkephalin (DPDPE) or deltorphin II caused only a minor and non-dose-related rise in GH secretion in neonatal rats. The relative importance of mu- and delta-receptors in stimulating GH secretion was also studied in older pups (day 20). i.c.v. administration of DAMGO stimulated GH secretion, while neither DPDPE nor deltorphin II consistently increased GH secretion. Furthermore, peripheral administration of either morphine or the highly selective mu-agonist sufentanil elicited marked GH secretion on postnatal day 20, but only combined administration of the mu-antagonist beta-funaltrexamine (beta-FNA) and the delta-antagonist naltrindole substantially diminished these responses. These results suggest that both mu- and kappa-opioid receptors are involved in the regulation of GH secretion in neonatal rats. While delta-receptors do not play a prominent independent role in this response, they may act synergistically with mu-receptors in producing stimulation.

One‐Step Fast Synthesis of <scp> <scp>Li</scp> </scp> <sub>4</sub> <scp> <scp>Ti</scp> </scp> <sub>5</sub> <scp> <scp>O</scp> </scp> <sub>12</sub> Particles Using an Atmospheric Pressure Plasma Jet (2013)

A one‐step process to fabricate crystalline Li 4 Ti 5 O 12 ( LTO ) particles directly from solution using an atmospheric pressure plasma jet ( APPJ ) is reported. This process uses Ti and Li ions‐containing salt solutions as the precursor, which is ultrasonically nebulized and then transported to the downstream of the APPJ using a carrier gas. With an extremely short contact time (<0.1 s) between the precursor droplets and the plasma jet, crystalline LTO can be fabricated in one step without additional rinse and postannealing steps. The LTO particle size can be effectively controlled using a preheater, the precursor solution composition and concentration, and the carrier gas flow rate. By properly adjusting the operating condition, particles of diameters from 100 nm to few μm with various morphologies can be obtained. When used as an electrode material, the resulting LTO powders fabricated under selected conditions show specific capacities over 100 mAh/g even at 50 C rate.
Semantic Model Vectors for Complex Video Event Recognition (2011)

We propose semantic model vectors, an intermediate level semantic representation, as a basis for modeling and detecting complex events in unconstrained real-world videos, such as those from YouTube. The semantic model vectors are extracted using a set of discriminative semantic classifiers, each being an ensemble of SVM models trained from thousands of labeled web images, for a total of 280 generic concepts. Our study reveals that the proposed semantic model vectors representation outperforms-and is complementary to-other low-level visual descriptors for video event modeling. We hence present an end-to-end video event detection system, which combines semantic model vectors with other static or dynamic visual descriptors, extracted at the frame, segment, or full clip level. We perform a comprehensive empirical study on the 2010 TRECVID Multimedia Event Detection task (http://www.nist.gov/itl/iad/mig/med10.cfm), which validates the semantic model vectors representation not only as the best individual descriptor, outperforming state-of-the-art global and local static features as well as spatio-temporal HOG and HOF descriptors, but also as the most compact. We also study early and late feature fusion across the various approaches, leading to a 15% performance boost and an overall system performance of 0.46 mean average precision. In order to promote further research in this direction, we made our semantic model vectors for the TRECVID MED 2010 set publicly available for the community to use (http://www1.cs.columbia.edu/~mmerler/SMV.html).
Prolonged electron emission as a method to fabricate a stable and bright dual ion/electron point source (2005)

A method based on prolonged (few hundreds of hours) electron emission has been developed to fabricate a stable dual ion/electron source with an electron emission current as high as 5μA, which is ∼100 times higher than that of any dual source reported previously. Once fabricated, the dual emitter can be switched interchangeably between ion and electron emission mode within a few minutes after changing the polarity of the extraction electrode. The achievement of such a stable and bright dual ion/electron point emitter is an important step towards the further development of single-column focused ion/electron beam systems.
Turbo codes on the fixed point DSP TMS320C55x (2002)

Turbo codes are introduced in 3rd generation wireless cellular standards for their superior coding gain. The MIPS requirements of turbo codes are however extremely high. This paper describes the implementation of a turbo-decoding algorithm on the TMS320C55x processor. The coding performance is evaluated with fixed-point arithmetic. A method to optimize the memory is also introduced to address the large data storage problem. The effect of finite word lengths is carefully examined to reduce the state metric normalization time and to achieve at the same time an acceptable bit error rate (BER). The coding gain of 5.8 dB for a BER of 10/sup -3/ in 6 iterations is achieved with a frame size of 1 K bits and 50 Hz frame rate. Total MIPS estimate when using the max Log-MAP algorithm is 46 MIPS.
Fractured Wellbore Stress Analysis: Sealing Cracks To Strengthen a Wellbore (2007)

Abstract Wellbore pressure containment, the maximum pressure that a wellbore can withstand before whole drilling mud begins to leak off into formations, defines the upper bound of the mud weight window. Drilling costs are heavily associated with this mud weight window in terms of expensive casing programs or nonproductive time because of narrow mud weight windows. Although various methods have been developed using different materials for curing mud losses, the performance has been poor as a result of the lack of engineering design for the materials and placement techniques. The commonly used "trial and error" approach reveals inadequate understanding of the challenge, although a number of advances have been accomplished in recent years. In this paper, results are reported from a fundamental study aimed at revealing the basic physics that control the success of treatments strengthening wellbores or widening the mud weight window. It first focuses on reviewing and identifying factors that can reduce the upper bound of this mud weight window, followed by analysis of wellbore strengthening that can increase this upper bound of mud weight window, especially by sealing hydraulically conductive cracks at the wellbore.
AutoDSS: A System Level KBE Tool for Vehicle Product Definition (2000)

<div class="htmlview paragraph">A key to shortening the design cycle is to shorten the initial or conceptual design phase. An enabling technology towards this goal is an architecture called the Design Support System (DSS), which is based on the virtual prototype concept. The DSS combines knowledge with hardware and software into a system that is a model for the design process. It produces a virtual prototype of the design and maintains an intelligent design document, which is automatically updated during the design process. A design domain dependent version for automotive design, known as “Automobile Design Support System” (AutoDSS) was developed in the CADTECH Research Lab at the University of Washington.</div>
Prevention of Residual Oil Combustion Problems by Use of Low Excess Air and Magnesium Additive (1965)

High-temperature corrosion from low melting ash deposits, low-temperature corrosion, and low-temperature deposits produced by condensed sulfuric acid are three potential problems associated with residual fuel oil firing in steam generators. This paper discusses test work carried out on a large unit type steam generator in an effort to alleviate these problems through low-excess air operation and the use of a magnesium additive. Results indicate that these two steps are of significant help.
Laboratory Study of Air Sparging: Air Flow Visualization (1993)

Abstract Laboratory flow visualization experiments, using glass beads as the porous medium, were conducted to study air sparging, an innovative technology for subsurface contaminant remediation. The purpose of these experiments was to observe how air flows through saturated porous media and to obtain a basic understanding of air plume formation and medium heterogeneity effects. The experiments indicate that air flow occurring in discrete, stable channels is the most probable flow behavior in medium to fine grained water saturated porous media and that medium heterogeneity plays an important role in the development of air channels. Several simulated scales of heterogeneities, from pore to field, have been studied. The results suggest that air channel formation is sensitive to the various scales of heterogeneities. Site‐specific hydrogeologic settings have to be carefully reviewed before air sparging is applied to remediate sites contaminated by volatile organic compounds.
The Role of MicroRNAs in Breast Cancer Stem Cells (2013)

The concept of the existence of a subset of cancer cells with stem cell-like properties, which are thought to play a significant role in tumor formation, metastasis, resistance to anticancer therapies and cancer recurrence, has gained tremendous attraction within the last decade. These cancer stem cells (CSCs) are relatively rare and have been described by different molecular markers and cellular features in different types of cancers. Ten years ago, a novel class of molecules, small non-protein-coding RNAs, was found to be involved in carcinogenesis. These small RNAs, which are called microRNAs (miRNAs), act as endogenous suppressors of gene expression that exert their effect by binding to the 3'-untranslated region (UTR) of large target messenger RNAs (mRNAs). MicroRNAs trigger either translational repression or mRNA cleavage of target mRNAs. Some studies have shown that putative breast cancer stem cells (BCSCs) exhibit a distinct miRNA expression profile compared to non-tumorigenic breast cancer cells. The deregulated miRNAs may contribute to carcinogenesis and self-renewal of BCSCs via several different pathways and can act either as oncomirs or as tumor suppressive miRNAs. It has also been demonstrated that certain miRNAs play an essential role in regulating the stem cell-like phenotype of BCSCs. Some miRNAs control clonal expansion or maintain the self-renewal and anti-apoptotic features of BCSCs. Others are targeting the specific mRNA of their target genes and thereby contribute to the formation and self-renewal process of BCSCs. Several miRNAs are involved in epithelial to mesenchymal transition, which is often implicated in the process of formation of CSCs. Other miRNAs were shown to be involved in the increased chemotherapeutic resistance of BCSCs. This review highlights the recent findings and crucial role of miRNAs in the maintenance, growth and behavior of BCSCs, thus indicating the potential for novel diagnostic, prognostic and therapeutic miRNA-based strategies.
Modifications of Human Growth Differentiation Factor 9 to Improve the Generation of Embryos From Low Competence Oocytes (2014)

Growth differentiation factor 9 (GDF9) is an oocyte-derived growth factor that plays a critical role in ovarian folliculogenesis and oocyte developmental competence and belongs to the TGF-β family of proteins. Recombinant human GDF9 (hGDF9) is secreted in a latent form, which in the case of the fully processed protein, has the proregion noncovalently associated with the mature region. In this study, we investigated a number of amino acid residues in the mature region of hGDF9 that are different from the corresponding residues in the mouse protein, which is not latent. We designed, expressed, and purified 4 forms of chimeric hGDF9 (M1-M4) that we found to be active in a granulosa cell bioassay. Using a porcine in vitro maturation model with inherent low developmental competence (yielding 10%-20% blastocysts), we tested the ability of the chimeric hGDF9 proteins to improve oocyte maturation and developmental competence. Interestingly, one of the chimeric proteins, M3, was able to significantly increase the level of embryo production using such low competence oocytes. Our molecular modeling studies suggest that in the case of hGDF9 the Gly(391)Arg mutation probably increases receptor binding affinity, thereby creating an active protein for granulosa cells in vitro. However, for an improvement in oocyte developmental competence, a second mutation (Ser(412)Pro), which potentially decreases the affinity of the mature region for the proregion, is also required.
