Application of Polypropylene Fibrillated Fibres for Reinforcement of Concrete and Cement Mortars (2016)

Polypropylene fibres have been applied for reinforcement of cement mortars and concrete for many years. The fibres restrict crack propagation and positively affect several concrete parameters. To improve the adhesion of polypropylene to cement matrix, geometrically deformed or modified fibres are commonly used. Good results are obtained by application of fibrillated fibres with the net-like structure obtained from the polypropylene types. The fibrillated polypropylene fibres were produced. The fibres were chopped to specified lengths and used for the reinforcement of concrete and cement mortars. The parameters of fresh concrete and mechanical parameters of reinforced concrete and mortar were determined. It was stated that the fibres do not affect the compressive strength of the reinforced concrete and mortar. The beneficial effect of fibres on the compressive strength of concrete is revealed after freezing and thawing cycles. The fibres influence the bending strength of the mortars. For mortars reinforced with fibrillated fibres a significant increase in the bending strength is observed. The increase in the bending strength results from enhanced interfacial adhesion and mechanical anchoring, which results from opening of the network structure and splitting of fibrillated fibres.
A family with an apparent HLA-DR triplet: evidence for exchange of functional HLA-DR beta-genes between different haplotypes. (1989)

Serological and protein analysis showed that HLA-DR1 and DR2 short (s) segregated together as one haplotype, resulting in a HLA-DR triplet as found in a family study. Both DR1 and DR2 molecules were coordinately expressed and were shown to function as restriction elements in antigen presentation assays. This unique HLA-DR1, 2s haplotype was further studied by Southern blot analysis. Based upon well-known restriction fragment length polymorphisms for the involved gene sets, i.e. DR1 and DR2 along with the DR type from the other haplotype, the genes as identified by restriction fragment length polymorphism of the triplet could be established. Pseudogenes, which are included in the previously described gene sets of HLA-DR1 and DR2 are apparently lacking in the triplet. We therefore postulate that during an unequal crossing-over event the DR beta-pseudogene of DR2 could be exchanged by a functional DR1 beta-gene.
The use of cytology to evaluate pericardial effusions. (1979)

Pericardial effusions from 27 patients were examined cytologically during the five-year period of 1973-1977. Malignant cells were found in eight cases (30 percent). In three of these patients malignancy was unsuspected clinically, and this was the first time the cancer was diagnosed. In addition, cytology often suggested the specific histological types and possible primary sites to be determined. Special stains were also found helpful. There were no false positive reports. Although the pericardial effusions from the remaining 19 patients were negative for tumor cells, metastatic carcinoma to the pericardium was discovered at autopsy in two of these cases. Thus, cytologic examination of pericardial fluid is an important tool in the diagnosis of malignancy, but false negative results may occur.
A Physiological Time Series Dynamics-Based Approach to Patient Monitoring and Outcome Prediction (2014)

Cardiovascular variables such as heart rate (HR) and blood pressure (BP) are regulated by an underlying control system, and therefore, the time series of these vital signs exhibit rich dynamical patterns of interaction in response to external perturbations (e.g., drug administration), as well as pathological states (e.g., onset of sepsis and hypotension). A question of interest is whether "similar" dynamical patterns can be identified across a heterogeneous patient cohort, and be used for prognosis of patients' health and progress. In this paper, we used a switching vector autoregressive framework to systematically learn and identify a collection of vital sign time series dynamics, which are possibly recurrent within the same patient and may be shared across the entire cohort. We show that these dynamical behaviors can be used to characterize the physiological "state" of a patient. We validate our technique using simulated time series of the cardiovascular system, and human recordings of HR and BP time series from an orthostatic stress study with known postural states. Using the HR and BP dynamics of an intensive care unit (ICU) cohort of over 450 patients from the MIMIC II database, we demonstrate that the discovered cardiovascular dynamics are significantly associated with hospital mortality (dynamic modes 3 and 9, p=0.001, p=0.006 from logistic regression after adjusting for the APACHE scores). Combining the dynamics of BP time series and SAPS-I or APACHE-III provided a more accurate assessment of patient survival/mortality in the hospital than using SAPS-I and APACHE-III alone (p=0.005 and p=0.045). Our results suggest that the discovered dynamics of vital sign time series may contain additional prognostic value beyond that of the baseline acuity measures, and can potentially be used as an independent predictor of outcomes in the ICU.
Monitoring packet traffic levels (2002)

Traffic levels in packet networks are currently monitored by measuring rates over time scales of the order of 15-30 minutes. Given the burstiness of packet traffic, such time scales are too coarse to accurately indicate resource usage. We relate the traffic monitoring problem to measurement results indicating the fractal nature of packet traffic. We consider the use of fractal statistics in developing accurate yet efficient descriptions of packet traffic. We consider several measurement alternatives, and on the basis of extensive simulation experiments with actual packet traces, we make the following conclusions: (i) the single parameter descriptions of burstiness considered, including the fractal correlation dimension, are inadequate and (ii) the peak-to-mean rates over carefully selected intervals can provide information on capacity exhaust. Useful engineering guidelines can be developed on the basis of a three parameter description, and the self-similarity of packet traffic can in principle be exploited to reduce measurement overhead.
Interaction of heparin with amphiphile assemblies and biocompatibility of the heparin complexes (1995)

Addition of heparin to preformed vesicles of a cationic surface-active compound, dioctadecyldimethylammonium bromide (DODAB), resulted in fast precipitation of the heparin/DODAB complex. On the other hand, heparin stabilized the vesicle composed of dipalmitoyl L-alpha-phosphatidylcholine (DPPC) which is a neutral lipid. However, DPPC precipitated with heparin by the addition of a small amount of stearylamine (SA), which is a cationic substance. Differential scanning calorimetry of the heparin/amphiphile mixtures showed that the heparin/DODAB complex possess a structure different from that of the original DODAB vesicle. The structure of the DPPC vesicle was unaffected by the addition of heparin, while the structure of the heparin/DPPC-SA complex was found to be different from that of the DPPC-SA vesicle. The interaction of heparin with vesicles depended on the nature of amphiphiles. Heparin was solubilized in organic solvent when complexed with DODAB or DPPC-SA vesicles. Polyurethaneurea membranes blended with heparin/DODAB or heparin/DPPC-SA complexes were highly nonthrombogenic, but somewhat cytotoxic.
Data Quality Assessment: A Case Study of PT JAS Using TDQM Framework (2019)

The success of a company in increasing profits and managing loss risk is largely determined by data. Good quality data can improve the quality of decision making at the top management level. PT JAS is a financial company that manages risk. Of course to support good risk management needs to be supported by good quality of data sources. The aim of this research is to identify data dimensions, analyze and measure the quality of data. So that, it can be used as a support for the company's strategy in managing risk and understanding the current conditions of data quality. In measuring this data quality, the writer uses a total data quality management (TDQM) framework. TDQM provides a common framework for facilitating understanding in data improv approach through data quality management. The steps taken in measuring data quality are identification of data to be measured, determining the dimensions of data quality used, measurement of data quality, and then analyze the measurement results. From the measurement results, obtained factors that cause data quality problems, for example the pattern of imports of debtor data in large numbers. In addition, there are no policies related to data quality management and from some validation function errors in the system. Therefore, by measuring the quality of data and analyzing the causes, companies can find out in advance the condition of the quality of company data and immediately formulate strategies and steps in order to improve and develop the quality of the data they have, so that data can be a useful and valuable asset.

It suggested that mifepristone is a more practical and hopeful drug in treating uterine leiomyoma.
Active hand tracking (2002)

This paper describes a system which uses multiple visual processes to detect and track hands for gesture recognition and human-computer interaction. This system is based on an architecture in which a supervisor selects and activates visual processes. Each process provides a confidence factor which makes it possible for the system to dynamically reconfigure itself in response to events in the scene. Visual processes for hand tracking are described using image differencing and normalized histogram matching. The result of hand detection is used by a recursive estimator (Kalman filter) to provide an estimate of the position and size of the hand. The resulting system provides robust and precise tracking which operates continuously at approximately 5 images per second on a 150 megahertz Silicon Graphics Indy.
Histological identification of <i>Helicobacter pylori</i>: comparison of staining methods (2000)

When H pylori are present, careful examination will almost always reveal them, whichever of these stains is used. However, the modified Giemsa stain is the method of choice because it is sensitive, cheap, easy to perform, and reproducible.
Modelling the business process to derive organisational requirements for information technology (1995)

Organisations today perceive information technology systems as vital to their success. The effective application of information from an organisational perspective can mean the difference between success or failure. The ORDIT (organisational requirements definition for information technology) approach was developed as a socio-technical systems based methodology, its purpose is to facilitate problem solvers and problem owners in developing the correct understanding of what is required, why it is required and when it is required, of the system. Within this paper we will present a case study in which the ORDIT methodology is applied to an information technology system for an accident and emergency department of an inner city hospital for the purpose of eliciting, representing and validating organisational requirements for information technology. The hospital recognizes that the introduction of an information system is vital and that its specification is fraught with danger. It was against this backdrop that the case study was performed.
Does Fundamental and Technical Analysis Reduce Investment Risk for Growth Stock? An Analysis of Taiwan Stock Market (2014)

In this paper, we implement methodology to empirically identify how individual trader can make profits by applying combined strategies of identifying fundamental and technical risk management. Our data is from Taiwan Economic Journal Database (TEJ), and covering information from 1991 to 2009. Proper risk management skills employed increase the momentum portfolio returns. We explore investment opportunity by examining firm level of financial factors, including profitability, operating efficiency, accounting conservatism and solvency. When investors obtain quotations and identify potential stocks, volume data of the key attributes of stocks usually goes overlooked as price-to-earnings ratio, market size, or even ex-dividend date even comes in priority. In order to justify the optimal timing of investment, we use the covariance between price and volume as a buying signal to filter portfolios for technical analysis. Result confirms selected portfolios earn significant excess returns which beat the market with long term holding period.
Object Detection, Tracking and Recognition for Multiple Smart Cameras (2008)

Video cameras are among the most commonly used sensors in a large number of applications, ranging from surveillance to smart rooms for videoconferencing. There is a need to develop algorithms for tasks such as detection, tracking, and recognition of objects, specifically using distributed networks of cameras. The projective nature of imaging sensors provides ample challenges for data association across cameras. We first discuss the nature of these challenges in the context of visual sensor networks. Then, we show how real-world constraints can be favorably exploited in order to tackle these challenges. Examples of real-world constraints are (a) the presence of a world plane, (b) the presence of a three-dimiensional scene model, (c) consistency of motion across cameras, and (d) color and texture properties. In this regard, the main focus of this paper is towards highlighting the efficient use of the geometric constraints induced by the imaging devices to derive distributed algorithms for target detection, tracking, and recognition. Our discussions are supported by several examples drawn from real applications. Lastly, we also describe several potential research problems that remain to be addressed.
Decoding how a soil bacterium extracts building blocks and metabolic energy from ligninolysis provides road map for lignin valorization (2016)

Sphingobium sp. SYK-6 is a soil bacterium boasting a well-studied ligninolytic pathway and the potential for development into a microbial chassis for lignin valorization. An improved understanding of its metabolism will help researchers in the engineering of SYK-6 for the production of value-added chemicals through lignin valorization. We used <sup>13</sup>C-fingerprinting, <sup>13</sup>C metabolic flux analysis (<sup>13</sup>C-MFA), and RNA-sequencing differential expression analysis to uncover the following metabolic traits: (i) SYK-6 prefers alkaline conditions, making it an efficient host for the consolidated bioprocessing of lignin, and it also lacks the ability to metabolize sugars or organic acids; (ii) the CO<sub>2</sub> release (i.e., carbon loss) from the ligninolysis-based metabolism of SYK-6 is significantly greater than the CO<sub>2</sub> release from the sugar-based metabolism of Escherichia coli; (iii) the vanillin catabolic pathway (which is the converging point of majority of the lignin catabolic pathways) is coupled with the tetrahydrofolate-dependent C1 pathway that is essential for the biosynthesis of serine, histidine, and methionine; (iv) catabolic end products of lignin (pyruvate and oxaloacetate) must enter the tricarboxylic acid (TCA) cycle first and then use phosphoenolpyruvate carboxykinase to initiate gluconeogenesis; and (v) <sup>13</sup>C-MFA together with RNA-sequencing differential expression analysis establishes the vanillin catabolic pathway as the major contributor of NAD(P)H synthesis. Therefore, the vanillin catabolic pathway is essential for SYK-6 to obtain sufficient reducing equivalents for its healthy growth; cosubstrate experiments support this finding. This unique energy feature of SYK-6 is particularly interesting because most heterotrophs rely on the transhydrogenase, the TCA cycle, and the oxidative pentose phosphate pathway to obtain NADPH.
Identifying spam in the iOS app store (2012)

Popular apps on the Apple iOS App Store can generate millions of dollars in profit and collect valuable personal user information. Fraudulent reviews could deceive users into downloading potentially harmful spam apps or unfairly ignoring apps that are victims of review spam. Thus, automatically identifying spam in the App Store is an important problem. This paper aims to introduce and characterize novel datasets acquired through crawling the iOS App Store, compare a baseline Decision Tree model with a novel Latent Class graphical model for classification of app spam, and analyze preliminary results for clustering reviews.
Helping students keep up with real-time captions by pausing and highlighting (2014)

We explore methods for improving the readability of real- time captions by allowing users to more easily switch their gaze between multiple visual information sources. Real-time captioning provides deaf and hard of hearing (DHH) users with access to spoken content during live events, and the web has allowed these services to be provided via remotely- located captioning services, and for web content itself. However, despite caption benefits, spoken language reading rates often result in DHH users falling behind spoken content, especially when the audio is paired with visual references. This is particularly true in classroom settings, where multi-modal content is the norm, and captions are often poorly positioned in the room, relative to speakers. Additionally, this accommodation can benefit other students who face temporary or "situational" disabilities such as listening to unfamiliar speech accents, or if a student is in a location with poor acoustics.
INVESTIGATION ON OPERATING CONDITIONS AND EFFICIENCY OPTIMIZATION OF RF-RF HYBRID PLASMA TORCHES (2023)

A numerical investigation on RF-RF hybrid plasma torches has been performed with the aim of selecting optimum operating conditions for different torch configurations, with or without intermediate injection of secondary gas. Results show the possibility of reducing considerably the sustaining power, while guaranteeing the required enthalpy content of the gas at the exit of the torch. Moreover, the existence of two separable sets of equilibrium configurations for the plasma has been found in some cases.
Pre‐treatment of peripheral blood progenitor cells with macrophage inflammatory protein‐1α induces prolonged survival of early progenitor cells over 6 weeks of long‐term culture (1998)

It has previously been shown that a combination of macrophage inflammatory protein-1alpha (MIP-1alpha) and interleukin (IL)-3 maintained human bone marrow (BM)-derived long-term culture-initiating cells (LTC-IC) for at least 8 weeks in vitro. We investigated colony- and cobblestone area-formation potential of peripheral blood progenitor cells (PBPC) at week 6 of long-term culture (LTC) in the absence of exogenous MIP-1alpha. but using cells which had been pre-incubated in the presence of MIP-1alpha for 40 h in liquid culture. The recovery of colony-forming cells (CFC) and cobblestone-area-forming cells (CAFC) after pre-incubation of PBPC with MIP-1alpha was up to threefold higher (P<0.05, n=5) than that of untreated controls. These results demonstrate that short-term pre-treatment of PBPC with MIP-1alpha induces long-lasting survival effects on early PBPC-derived progenitors in vitro.
System for loading slab-gel holders for electrophoresis separation (2023)

A slab-gel loading system includes a prismatic chamber for filling a plurality of slab-gel holders simultaneously. Each slab-gel holder comprises a pair of spaced apart plates defining an intermediate volume for gel containment. The holders are vertically positioned in the chamber with their major surfaces parallel to the chamber end walls. A liquid inlet is provided at the corner between the bottom and a side wall of the chamber for distributing a polymerizable monomer solution or a coagulable colloidal solution into each of the holders. The chamber is rotatably supported so that filling can begin with the corner having the liquid inlet directed downwardly such that the solution is gently funneled upwardly, without mixing, along the diverging side and bottom surfaces. As filling proceeds, the chamber is gradually rotated to position the bottom wall in a horizontal mode. The liquid filling means includes a plastic envelope with a septum dividing it into two compartments for intermixing two solutions of different density and thereby providing a liquid flow having a density gradient. The resulting gels have a density gradient between opposite edges for subsequent use in electrophoresis separations.
Acriflavine-Resistant Mutant of <i>Streptococcus cremoris</i> (1977)

Selection for resistance to acriflavine in Streptococcus cremoris resulted in cross-resistance to the drugs neomycin, streptomycin, ethidium bromide, mitomycin C, and proflavine. Furthermore, the mutants showed resistance to lytic bacteriophages to which the parental strain was sensitive, and, unlike the parent, the mutants grew well at higher temperatures (40 degrees C). Revertants selected independently either for temperature sensitivity or for acriflavine sensitivity lost resistance to all the drugs and dyes but retained the bacteriophage resistance phenotype. The acriflavine-resistant mutation resulted in an increase in resistance by the bacterial cells to sodium dodecyl sulfate, a potent solvent of lipopolysaccharide and lipoprotein. It is suggested that the acriflavine resistance mutation determines the synthesis of a membrane substance resistant to higher temperatures.
Review of Thermal Properties of Graphene and Few-Layer Graphene: Applications in Electronics (2015)

We review thermal properties of graphene and few-layer graphene, and discuss applications of these materials in thermal management of advanced electronics. The intrinsic thermal conductivity of graphene - among the highest of known materials - is dominated by phonons near the room temperature. The examples of thermal management applications include the few-layer graphene heat spreaders integrated near the heat generating areas of the high-power density transistors. It has been demonstrated that few-layer graphene heat spreaders can lower the hot-spot temperature during device operation resulting in improved performance and reliability of the devices.
Filtered Microaggregate‐Free Erythrocyte Concentrates with 35‐Day Shelf Life (1981)

Abstract. Packed erythrocytes which are white cell and microaggregate poor and virtually platelet free, with a long shelf life (35 days), can be prepared from a routinely used plastic pack system incorporating a cotton wool filter module. The filtered packed cells have improved physical and biochemical properties after prolonged storage, and with acceptable autologous erythrocytic survivals the system lends itself to routine clinical practice. It avoids the need for microaggregate filters at administration, at the same time reducing the immunogenicity of the transfused blood. Blood component harvesting is not compromised.
