Temporal event clustering for digital photo collections (2005)

Organizing digital photograph collections according to events such as holiday gatherings or vacations is a common practice among photographers. To support photographers in this task, we present similarity-based methods to cluster digital photos by time and image content. The approach is general and unsupervised, and makes minimal assumptions regarding the structure or statistics of the photo collection. We present several variants of an automatic unsupervised algorithm to partition a collection of digital photographs based either on temporal similarity alone, or on temporal and content-based similarity. First, interphoto similarity is quantified at multiple temporal scales to identify likely event clusters. Second, the final clusters are determined according to one of three clustering goodness criteria. The clustering criteria trade off computational complexity and performance. We also describe a supervised clustering method based on learning vector quantization. Finally, we review the results of an experimental evaluation of the proposed algorithms and existing approaches on two test collections.
Improvement in Aging Characteristics by Zn Doping of Electron-Beam Evaporated SrS:Ce Thin-Film Electroluminescent Devices (1997)

Aging characteristics of electron-beam evaporated SrS:Ce thin film electroluminescent devices have been improved by using a SrS:Ce and ZnS mixture source pellet. For the Zn-doped device, luminance is maintained at more than 60% of the initial value and threshold voltage remains constant for more than 1000 hours of aging at 500 Hz drive. A rapid decrease in luminance corresponds to a decrease in dynamic space charge, and is reduced by Zn doping. In contrast, a slow decrease in luminance is attributed to a change in the electron emission characteristics of phosphor-insulator interfaces.
SLC4A4 function in vas deferens epithelial cells (2006)

Expression of pSLC4A4 variant NBCe1B (pancreatic form) is over 30 times larger than that of variant NBCe1A (kidney form) in primary cultures of porcine vas deferens epithelial cells or the PVD9902 cell line. PVD9902 cells constitutively expressing shRNA targeted to a specific 21‐bp segment of the common coding sequence shared by porcine SLC4A4 NBCe1A and e1B, revealed, by means of absolute quantitative RT‐PCR, a 5.65‐fold decrease in the levels of NBCe1B and a 2.55‐fold decrease of NBCe1A expression when compared to non‐transfected PVD9902 cells, as a clear indication of RNA interference – this cell population is here denominated as pSLC4A4‐ knockdown (pSLC4A4‐ kd ). HCO 3 − ‐dependent ion transport at the basolateral membrane of apical‐nystatin permeabilized cells revealed that anion transport in non‐transfected cells is 50% larger than in the pSLC4A4‐kd cells. Reduction of the HCO 3 − ‐dependent anion transport in the apical‐nystatin permeabilized model by DNDS is 54% in control cells and 27% in the pSLC4A4‐kd. These results indicate that primary and immortalized vas deferens epithelia secreted bicarbonate by an SLC4A4‐dependent mechanism that likely influences male fertility.

Prediction of radiation pressure force exerted on moving particles by the two-level skeletonization (2014)

A fast full-wave method for computing radiation pressure force (RPF) exerted by shaped light beams on moving particles is presented. The problem of evaluating RPF exerted on a moving particle by a single excitation beam is converted into that of computing RPF's exerted on a static particle by multiple beams. The discretization of different beams leads to distinct right hand sides (RHS's) for the matrix system. To avoid solving each RHS by the brute-force manner, the algorithm conducts low-rank decomposition on the excitation matrix consisting of all RHS's to figure out the so-called skeleton light beams by interpolative decomposition (ID). The peak memory requirement of the skeletonization is a bottle-neck if the particle is large. A two-level skeletonization scheme is proposed to solve this problem. Some numerical experiments on arbitrarily shaped homogeneous particles are performed to illustrate the performance and capability of the developed method.
Blind adaptive filtering for non-invasive extraction of the fetal electrocardiogram and its non-stationarities (2008)

The objective is to extract automatically a beat-to-beat fetal electrocardiogram (fECG) from a maternal electrocardiogram (mECG) using surface electrodes placed on the maternal abdomen and to derive fetal PR, QT, QTc, and QS durations to allow early diagnosis and monitoring treatment of certain fetal cardiac disorders. mECG and abdominal noise in abdominal maternal recordings can be orders of magnitude stronger than the fECG signal and the P and T waves that are embedded in them. A two-stage blind adaptive filtering algorithm was used for fECG extraction, the first stage using frequency-domain electrocardiogram features and the second considering time-domain features. Three channels of abdominal recordings were obtained from 12 patients at 20-40 weeks of gestation. In each case beat-to-beat unaveraged fECGs were isolated. The combined filter allowed identification of diagnostically important PR, QT, and RR durations. Comparison with synthetic data is also included.
Effect of Circumferential Location of Radial Injection on Rotordynamic Performance of Hybrid Air Foil Bearings (2018)

Air foil bearings (AFBs) are introduced as promising bearings for oil-free turbomachinery applications. AFBs provide reliable operation at high speed and high temperature with negligible power loss. Hybrid Air Foil Bearing (HAFB) technology utilizes the radial injection of externally pressurized air into the traditional hydrodynamic AFB’s film thickness through orifices attached to the top foil. Previous studies have reported enhancement in the rotordynamic stability of HAFBs compared to traditional hydrodynamic AFBs. HAFBs have several orifices distributed in the circumferential direction. In this study, the effect of the circumferential location of radial injection on the rotordynamic performance of the rotor-HAFB is studied. Analytical and experimental evaluations of the rotordynamic performance of a rotor supported by two single-pad HAFBs are presented. Parametric studies are conducted using three sets of single-pad HAFBs. The circumferential locations of orifices are different for each set. The presented simulation analyses consist of time-domain orbit simulation and frequency-domain modal analysis. Imbalance responses of rotor-HAFB were measured with various orifice locations and the results agree well with predictions. Comparison of the rotordynamic performance of HAFBs with different orifice configurations demonstrate substantial improvement in rotordynamic stability as well as enhancement in the stiffness and damping coefficients of HAFBs by choosing the best circumferential location for radial injection to control rotor eccentricity and attitude angle.
EVALUATION OF ECA GESTURE STRATEGIES FOR ROBUST HUMAN-MACHINE INTERACTION (2008)

Embodied Conversational Agents (ECAs) offer us the possibility to design pleasant and efficient human-machine interaction. In this paper we present an evaluation scheme to compare dialogue-based speaker authentication and information retrieval systems with and without ECAs on the interface. We used gestures and other visual cues to improve fluency and robustness of interaction with these systems. Our tests results suggest that when an ECA is present users perceive fewer system errors, their frustration levels are lower, turn-changing goes more smoothly, the interaction experience is more enjoyable, and system capabilities are generally perceived more positively than when no ECA is present. However, the ECA seems to intensify the users' privacy concerns.
Tetrasomic segregation in the naturally occurring autotetraploid Allium nevii (Alliaceae) (2008)

Allozyme markers were used to test for tetrasomic inheritance (versus monogenic-disomic or digenic-disomic inheritance) in a naturally occurring autotetraploid population of Allium nevii (Alliaceae). Twenty progenies representing both di-allelic and tri-allelic plants were studied for segregation at three loci (Adh1. Fe2. and Idh2). All the progenies segregated according to the expected ratios for tetrasomic inheritance of codominant genes, assuming chromosomal segregation. The monogenic-disomic model of inheritance was easily rejected by x2 tests. However, only by pooling progeny arrays from di-allelic symmetric heterozygous parents was it possible to statistically reject the digenic-disomic model of inheritance for the three loci analyzed. The present study therefore provides further evidence for an autotetraploid origin of tetraploid A. nevii and is an important addition to a growing body of literature suggesting autopolyploidy and polysomic inheritance may be more frequent in natural plant populations than has previously been hypothesized.

A case of maternal hyperparathyroidism presenting as neonatal tetany. (1975)

A three-week-old infant presented with tetany and with serum calcium and phosphate levels compatible with the diagnosis of hypoparathyroidism. Investigation of the asymptomatic mother revealed serum calcium and phosphate levels and urinary phosphate clearance values diagnostic of hyperparathyroidism. The maternal hyperparathyroidism was treated by removal of a parathyroid adenoma.
Hydrodynamic and thermal modelling of a high temperature spouted bed reactor with a draft tube (1990)

Abstract A new multi‐region, nonisothermal computer model of a spouted bed reactor with a draft tube has been developed. The model rigorously accounts for the mass, momentum, and energy interactions between the annulus and the spout both above and below the base of the draft tube. Additional reaction due to the residence time of the gases in the fountain region is also accounted for. Investigations involving the ultra‐rapid ultrapyrolysis of propane indicate that a spouted bed reactor with a draft tube is ideal for very fast reactions of this type as both high heating rates and short reactant gas residence times can be achieved within the reactor. Simulations indicate the reactor to be capable of heating the spout gases at maximum rates between 50 000 and 90 000 K/s. Gas residence times of 30 ms or less within the draft tube and 400 ms or less in the reactor were predicted by the model for conditions typical of those required for propane ultrapyrolysis.

Abstract 2502: Bioengineered-induced cancer-like stem cells: characterization and applications (2016)

Abstract Cancer stem cells (CSCs) are a small subset of tumor cells capable of self-renewal, tumor initiation, and growth. Isolation, expansion, and differentiation of CSCs in the proper stem niches remain a topic of great debate. To address some of the challenges, we developed bioengineered-induced cancer like stem cells (iCLSCs) through in vitro oncogenic reprograming of C57BL/6 mouse embryonic stem cells (mESCs). We constructed retroviral plasmids through integration of well-defined oncogenic elements such as SV40LTg and HrasV12 into a mouse stem virus long terminal repeat (MSCV-LTR) plasmid fused with either a GFP or RFP gene. We successfully acquired these bioengineered-iCLSCs through retroviral introduction alongside with FACS sorting of positively infected mESCs. We then cultured the bioengineered-iCLSCs on mouse embryonic fibroblast (mEF) feeder cells. Bioengineered-iCLSCs expressed the introduced oncogenic genes and showed enhanced proliferation similar to cancer cells. In addition, we ascertained the unhampered stem properties of the bioengineered-iCLSCs by examining the maintenance of alkaline phosphatase activity as well as the expression of mouse stem cell marker SSEA-1. Furthermore, the orthotopic inoculation of these bioengineered-iCLSCs into either the mammalian fat pad or the ovarian bursa of female C57BL/6 mice lead to the formation of teratomas in supportive niches. Interestingly, the teratomas formed in the ovarian bursa exhibited malignant and immature features, whereas the iCLSCs introduced to the mammary fat pad were not able to generate teratomas with similar features. These observations call for additional research to identify the dependency on a supportive niche and their role in metastasis based on a tumor-favorable microenvironment. Our study helped to establish the use of in vitro oncogenic reprograming to generate bioengineered-iCLSCs and suggests the potential application for the initiation of organ-specific, malignant tumor formation in an orthotopic small animal cancer model.

CHEMICAL AND ULTRASTRUCTURAL COMPARISON OF SYNTHETIC AND PATHOLOGIC MEMBRANE SYSTEM (1964)

Characteristic membranous bodies have been previously reported in the cytoplasm of the cerebral neurons in Tay-Sachs disease (1) (Fig. 1). Subsequently (2) these lamellated particles were isolated from homogenized autopsy tissue by differential and density gradient centrifugation and subjected to extensive chemical analysis. The membranous cytoplasmic bodies (MCB) were found to consist of about 50 per cent (dry weight) gangliosides and could account for the accumulation of this complex sphingolipid which characterizes this lipid-storage disease. The appearance and composition of the MCB suggested: (1) that they might arise from an alteration of cytoplasmic organelles, or (2) that they were formed spontaneously by interaction of the component lipids in a fashion analogous to myelin figure formation (3). Chemicals approximating the known composition of the MCB were combined in proper proportion in vitro as a test of this latter hypothesis. The resultant aggregates were examined with light and electron microscopy.
PatRICIA -- A Novel Programming Model for IoT Applications on Cloud Platforms (2013)

Cloud computing technologies have recently been intensively exploited for the development and management of large-scale IoT systems, due to their capability to integrate diverse types of IoT devices and to support big IoT data analytics in an elastic manner. However, due to the diversity, complexity and scale of IoT systems, the need to handle large volumes of IoT data in a nontrivial manner, and the plethora of domain-dependent IoT controls, programming IoT applications on cloud platforms still remains a great challenge. To date, existing work neglects high-level programming models and focuses on low-level IoT data and device integration. In this paper, we outline PatRICIA, which aims at providing an end-to-end solution for high-level programming and provisioning of IoT applications on cloud platforms. We present a novel programming model, based on the concept of intent and intent scope. Further, we introduce its runtime for dealing with the complexity, diversity and scale of IoT systems in the cloud. Our programming model defines abstractions to enable easier, efficient and more intuitive development of cloud-scale IoT applications. To illustrate our programming model, we present a case study with real-world applications for controlling and managing electric vehicles.
Induction of pathogen defence genes in parsley (Petroselinum crispum L.) plants by ozone (1994)

Synopsis Parsley ( Petroselinum crispum L.) is known to respond to pathogen attack by the synthesis of furanocoumarins and to UV-irradiation by the synthesis of flavone glycosides, whereas ozone treatment results in the induction of both pathways. Ozone treatment (200 nl 1 −1 , 10 h) of parsley seedlings results in an increased mRNA level of early genes within 3 h [pathogenesis related proteins PR1, PR2 and an elicitor-induced protein with unknown function (Eli 16)], of intermediate induced genes within 6 h [phenylalanine ammonia-lyase (PAL), 4-coumaroyl-CoA ligase (4CL), chalcone synthase (CHS)], and of late genes within 12 h [hydroxyproline-rich glycoprotein (HRGP), peroxidase (POD)]. 2D-PAGE of in vitro translated poly(A) + RNA isolated from ozone-treated parsley seedlings revealed about 20 induced and 10 repressed translation products. A cDNA library from parsley seedlings was differential screened, yielding several induced cDNA clones. One of the ozone-induced cDNA clones could be identified as coding for PR1-1 by hybrid-selected in vitro translation and by DNA sequence analysis.
Abstract 3207: Ratio of Microparticles To Endothelial Progenitor Cells Is Increased In A Diabetic Population (2008)

Diabetes Mellitus (DM) is strongly associated with a high incidence of cardiovascular disease (CVD) although often individuals show no symptoms or signs of disease. Therefore, quantitative measures are needed to distinguish those diabetic patients at higher risk for CV events. Cell derived microparticles (MPs), submicron membrane vesicles released from activated cells, and endothelial progenitor cells (EPCs) are mediators of cellular damage and endothelial reparative capacity respectively. Both are emerging biomarkers of vascular health and have been assessed individually in diabetic populations. To extend on this, we examined whether the relationship of MPs to EPCs could be used as a potential index of vascular pathology. Plasma samples were collected from patients with early-stage (ES, Diagnosis&lt;1yr, n=11, 51±4yrs, 7.2±0.5% HbA1c) and long-term (LT, Diagnosis&gt;5yrs, n=21, 64±3yrs, 7.1±0.3% HbA1c) with type 2 DM and compared to age related healthy volunteers (H, n=18, 57±3yrs, 5.3±0.7% HbA1c). EPCs positive for CD133 + /CD34 + and MP subtypes, AnnexinV + (AnnV + ), platelets (CD41 + ), monocytes (CD14 + ) and endothelial (CD144 + ) were measured by flow cytometry. Pro-coagulant microparticles and quantification of soluble proteins was measured using ELISA based methods. A significant relationship was found between MPs and EPCs which correlated with disease duration (H vs. ES vs. LT). Significant changes of pro-coagulant MPs ( P =0.02) and AnnV + MPs ( P =0.02) were noted. Of particular interest, the ratio of CD144 + MPs/EPC increased dramatically ( P =0.009) followed by ratios of AnnV + ( P =0.01), CD41 + ( P =0.01) and CD14 + ( P =0.03) MPs/EPCs. These indices of compromised vascular function were highest in the LT group despite intensive statin therapy (LDL mg/dL, 109±8 in H, vs. 80±7 in LT, P =0.01). Of note, the ratio of endothelial MPs/endothelial progenitor cells (CD144 + MPs/EPCs) was more informative than CRP and a range of inflammatory mediators. This is the first report of a relationship of MPs and EPCs in DM. This ratio provides a quantitative measurement of both pro-coagulant and endothelial injury and can identify DM patients with potentially increased risk of CV disease.
The removal of acetylene from hydrocarbon gases (1950)

Abstract The presence of acetylene in gas mixtures from vapour‐phase cracking of petroleum is a complication in the use of hydroxy‐alkylamine solutions of cuprous salts for concentration of ethylene. 1 Acetylene is frequently also a deleterious impurity in ethylene separated from such gases by other methods of gas separation. Two methods arc described for eliminating the acetylene from ethylene‐containing gases, one for ethylene fractions containing no more than traces of hydrogen, the other for mixtures containing hydrogen in substantial amounts. In the absence of hydrogen the acetylene impurity can be preferentially oxidized, using copper as catalyst, the small amount of residual excess oxygen which is necessarily added reacting with ethylene on the same catalyst and at the same temperature to give a gas free from both acetylene and oxygen. When hydrogen is present in amounts in excess of 4% (molar), small amounts of acetylene impurity, such as 0·5 to 1·0% (molar), can be preferentially hydrogenated without affecting the ethylene by the use of a reduced nickel‐chrome catalyst, the preparation of which is described. The efficiency of this catalyst is adversely affected by the presence of certain sulphur bodies.
Drilling Fluid Selection Methodology for Environmentally Sensitive Areas (2013)

Abstract When operating in areas of Africa which are particularly sensitive environmentally selection of drilling fluids should take into account both technical and environmental criteria in regards to the treatment and disposal of the cuttings and excess fluids. In this particular case the operator's choice of drilling fluid during its exploration and appraisal campaign was driven primarily by the need to use fluids with green credentials, and the fact that the exploration wells were not particularly demanding from a technical point of view. However, it was recognised that a system with improved technical performance woud be required when drilling the anticipated, more demanding, high angle and extended reach wells during the development drilling. When enough core and drill cuttings became available a thorough study was performed which comprised shale characterisation and inhibition testing. Seven drilling fluid compositions were tested, six water based and one synthetic based. A simple rating method was devised for ranking technical and environmental performance as well as treatment and disposal options for each fluid. The synthetic based mud was the strongest technically followed by an amine-modified high-performance water based system. It was shown that both can be combined with techno-economically feasible treatment and disposal options that minimise environmental impact.
Immunoradiometric assay of corticotropin with use of avidin-biotin separation. (1989)

We have developed a "sandwich"-type immunoradiometric assay for corticotropin (ACTH), with a detection limit of 2 ng/L. Two antibodies are used: a mouse monoclonal antibody directed against ACTH[1-17] and labeled with 125I; and a purified polyclonal goat antibody directed against ACTH[34-39] and conjugated to biotin. We could separate 125I-labeled antibody bound to ACTH from 125I-labeled antibody not bound to ACTH by using an avidin-biotin bridge, with avidin bound to a polystyrene ball. This assay reacts with ACTH[1-39] but shows no reaction with ACTH fragments [1-24], [1-17], or [34-39], or with melanotropin, endorphins, or lipotropin. This assay is sensitive enough to detect ACTH in plasma of all normal adults. Concentrations measured in 94 adults between 0800 and 1000 hours were normally distributed on a log scale, with a mean of 19.5 ng/L and a 95% range of 7.1 to 53.8 ng/L. Dexamethasone given at 2300 hours to 14 adults suppressed ACTH to less than 4 ng/L in 13 of the subjects and to 8 ng/L in the 14th. Metyrapone given to 13 adults at 2300 hours increased ACTH to 245.3 ng/L (95% range, 90.1 to 667.7 ng/L). This assay accurately classified patients with disorders of the adrenal system.
