Using the Beacon Eechnology on Improvement of Inventory and Logistics Curriculum Training (2018)

The purpose of this study is to use beacon technology to develop an active data feedback system. Manufacturers are cooperators who can continue to share realistic data about inventories and logistics with colleges, and colleges can improve the inventory and logistics curriculum training based on these realistic data. The system involved three parts, including the tag of Bluetooth low energy (BLE) technology, a smartphone APP as a reader, and a cloud database. When the tag is installed on a shelf of a warehouse or logistics facility, it can continue to actively collect all of the changing data about inventories and logistics and feed it back to the cloud database. The system focuses on active data feedback. Therefore, it is impossible to cause a heavy loading on manufacturers. When students access the cloud database, they can use these real data to learn how establish a fit inventory management approach and logistics decision. Thus, the system could help colleges to train students on practical abilities in inventory and logistics curriculum. Therefore, the system could improve the lack of existing inventory and logistics curriculum training.
Digital identity applied to telematic voting involving European citizens. Social and legal implications (2010)

This paper describes the characteristics of systems of electronic voting in which both the vote itself and the authorization to vote circulate through computer networks (telematic voting), with a focus on the problems arising from the need to ensure correct identification of citizens seeking to access the voting system in a Europe-wide environment. The advantages offered by such a system are discussed, as are the major social and legal implications these solutions may entail.

The coating mechanics that describes high-speed coating application in terms of process variables is explained. Finally, recent achievements with fibers coated at high speeds are presented.
Previous Angina Alters In-Hospital Outcome in TIMI 4 (1995)

Previous angina confers a beneficial effect on in-hospital outcome after acute myocardial infarction. The reasons for this benefit are uncertain, but one potential mechanism for this observation may be ischemic preconditioning.
Mite populations on grapes: Effect of sulfur dust treatments on predatory mites and red spider mite (1950)

The annual rise and fall of populations of the Pacific mite—Tetranychus pacificus McG—and the Willamette mite— Tetranychus willamettei McG—on grapes has puzzled growers and entomologists for years. In the fall of 1949 the last explanatory link was supplied.
Antisense Oligonucleotides in the Study of Central Mechanisms of the Cardiovascular Regulation (2000)

In the past several years, the progress in the development of molecular biology and the elucidation of gene sequences has created new approaches for studying biological functions and developing new diagnostic and therapeutic strategies. One of the most exciting advances has been the development of antisense technology, which represents a new strategy allowing modulation of protein synthesis with high specificity by preventing protein expression at the level of RNA or DNA. Many classical pharmacological approaches in neurobiological research are often based on the inhibition of biologically active proteins, such as receptors for neurotransmitters, or enzymes involved in neurotransmitter synthesis or degradation. The use of antisense oligodeoxynucleotides offers an alternative tool to manipulate selectively the expression of neurotransmitters or their receptors in neuronal tissue. This approach is especially useful when selective, high-affinity antagonists are not available. As a result, this technology has gained acceptance in the study of cell signalling mechanisms and the molecular basis of neuronal function. This paper provides a brief background to the antisense technique and explores methodological aspects, particularly in the whole animal. The use of the antisense technology in studies focused on central mechanisms regulating the cardiovascular system is then discussed.
Effects of growth factors and cytokines on osteoblast differentiation (2006)

In summary, the osteoblast lineage consists of mesenchymal stem cells which exhibit self-renewal and may include both multipotent cells and those of more restricted potentials. Commitment of these cells to the osteoblast lineage is likely to be mediated by the transcription factor TAZ, resulting in committed monopotent osteoprogenitor cells with extensive proliferative capacity. Differentiation of the mature osteoblast is ultimately regulated by transcription factors, including Cbfa-1/Runx-2 and osterix. A diagramatic schema of the osteoblast lineage and its features is shown in Fig. 2.
Evaluation of CA 125 as a serum marker of hepatocellular carcinoma (1990)

Serum CA 125 concentrations were raised in 90.4% of 115 southern African black patients with hepatocellular carcinoma. Seventy-four percent of 62 patients with amebic hepatic abscess, 60% of 40 patients with chronic hepatic parenchymal disease (chronic hepatitis or cirrhosis), and 60.9% of 41 patients with acute viral hepatitis also had raised values. The median serum CA 125 concentration for patients with hepatocellular carcinoma differed significantly from the benign hepatic disease groups analysed (p less than 0.0002). Serum alpha-fetoprotein levels were raised in 90.4% of the 115 hepatocellular carcinoma patients. CA 125 is thus a highly sensitive marker for hepatocellular carcinoma, but lacks specificity.
Quantification of Nitrate−π Interactions and Selective Transport of Nitrate Using Calix[4]pyrroles with Two Aromatic Walls (2013)

Herein we disclose the results of our investigations regarding the interactions between the biologically relevant nitrate oxoanion and several "two-wall" aryl-extended calix[4]pyrroles. There exists a clear relationship between the electronic nature of the aromatic walls of the calix[4]pyrroles and the stability of the nitrate⊂calix[4]pyrrole complex. This suggests that NO3(-)-π interactions have an important electrostatic component. We provide energetic estimates for the interaction of nitrate with several phenyl derivatives. Additionally, we report solid-state evidence for a preferred binding geometry of the nitrate anion included in the calix[4]pyrroles. Finally, the "two-wall" aryl-extended calix[4]pyrroles show excellent activity in ion transport through lipid-based lamellar membranes. Notably the best anion transporters are highly selective for transport of nitrate over other anions.
Fly ash and coal conversion by-products (1989)

This book includes in papers concerned with the by-products of SO{sub 2} control technologies - for example, wet scrubbing, sorbent injection, FBC, LIM, coal beneficiation, etc. With world-wide efforts to control acid precipitation, the amounts of these materials are steadily increasing. Characterization shows them to be easily as complex as coal ash, with indications of undesirable sulphide reported for the first time. These products do not adapt easily to existing ash utilization schemes, but promising applications of FBC ash to Portland cement-free concrete and other structural products were discussed. In another promising utilization option, it is shown that soon-to-be-commercialized foamed glass can be made from fly ash. Materials design and processing for this large-scale application are reported to be dependent only on ash composition rather than physical properties. The authors present knowledge of the microstructure, mineralogy and properties of fly ashes. In particular, XRD and TEM studies of the NISTs fly ash standard reference materials have led to quantification of the crystalline phases and a nanostructure-level look at phase separation and crystallization in the glass phases.

Review of rare earth doped fibre lasers and amplifiers (1988)

Recent developments in rare earth doped fibre lasers and amplifiers are reviewed. Fibre lasers have been made to operate at a variety of wavelengths, including the important 1.3 μm, 1.55 μm and the 2 to 3 μm regions in the infrared. The spectra of the rare earth ions and the nature of the host materials that make such lasing wavelengths possible are discussed. Methods for the manufacture of rare earth doped fibres are reviewed. A number of cavity designs for fibre lasers have been demonstrated, which have facilitated low loss coupling to transmission fibres, single longitudinal mode operation, Q-switching and mode locking. The performance of these systems is described. The operation of rare earth doped fibre amplifiers is also discussed.
A novel LMNA mutation (R189W) in familial dilated cardiomyopathy: evidence for a 'hot spot' region at exon 3: a case report (2010)

We describe a case of a patient with idiopathic dilated cardiomyopathy and cardiac conduction abnormalities who presented a strong family history of sudden cardiac death. Genetic screening of lamin A/C gene revealed in proband the presence of a novel missense mutation (R189W), near the most prevalent lamin A/C mutation (R190W), suggesting a "hot spot" region at exon 3.
Antihypertensive Effects of a Mixed Endothelin-A- and -B-Receptor Antagonist, J-104132, Were Augmented in the Presence of an AT1-Receptor Antagonist, MK-954 (2000)

Summary: The single oral administration of a mixed endothelin-A-and -B- (ETA/ETB) receptor antagonist, J-104132 (L-753,037) decreased the blood pressure in conscious spontaneously hypertensive rats (SHR), stroke-prone SHR (SHRSP) and Dahl salt-sensitive hypertensive rats fed high-salt diet (DS-H) at doses of 3 and 10 mg/kg, with a duration of approximately 24 h. The magnitude of the antihypertensive effects was greater in DS-H than in SHR and SHRSP. Preproendothelin-1 mRNA expression in the kidney and aorta was greater (about twofold) in DS-H than that in normotensive Dahl salt-resistant rats fed high-salt diet (DR-H), while there was no difference in preproendothelin-1 mRNA expression between SHR and Wistar Kyoto rats (WKY). An AT1-receptor antagonist, MK-954 (Losartan), also attenuated hypertension in SHR and SHRSP at oral doses of 3 and 10 mg/kg, but had no effect in DS-H. The concomitant treatment with MK-954 and J-104132 showed additive antihypertensive effects in SHR and SHRSP. In DS-H, MK-954 potentiated the antihypertensive effects of J-104132. From these results, we suggest that: (1) the contribution of endothelin (ET) to the maintenance of hypertension is greater in salt-sensitive hypertensive models than in SHR and SHRSP; (2) the antihypertensive efficacy of ETA/ETB blockade is augmented by AT1-receptor blockade; (3) ET blockers alone or in combination with AT1 antagonists could be useful in the treatment of hypertension for patients who do not respond adequately to renin-angiotensin system inhibitors alone.

Allotype-defined mRNA for rabbit immunoglobulin H and L chains isolated from rabbit-mouse hybridomas. (1983)

Improved procedures have expedited the formation and propagation of stable rabbit-mouse hybridomas (RMH) that secrete rabbit immunoglobulin (Ig) chains and that serve as sources for allotype-defined mRNA, specifying both constant and variable regions of rabbit Ig. The Ig-secreting hybridomas were stabilized by multiple recloning steps and eventually attained a 90% frequency of cells secreting rabbit Ig chains. Stabilized RMH were propagated in vivo in nude (athymic) and in some instances in conventional BALB/c mice. Rabbit Ig products secreted by these RMH cell lines were isolated and were shown to have amino acid sequence characteristics of rabbit Ig chains and that are distinct from those of the mouse. Preparative amounts of polyadenylated RNA-(poly(A) RNA) encoding allotype-defined rabbit Ig chains were isolated from RMH grown as solid tumors. Poly(A) RNA encoding a b4 L chain from one RMH (12F2) and an a3 H chain from another (7D2) were purified 10-fold by sucrose density gradient centrifugation and were characterized in an in vitro translation system. The mRNA encoding the b4 allotype had an S value of 12 and directed the synthesis of a rabbit precursor L chain with m.w. 27,500. Radiochemical amino acid sequence analysis of the L chain precursor has shown it to include a 22 residue leader sequence with a leucine profile similar to that of murine L chain precursors. Analysis of the mRNA encoding the a3 H chain revealed it has an S value of 16 and directed the synthesis of an Ig chain with a m.w. identical to that of the rabbit H chain secreted by the RMH.
Lactone; XIII.<sup>1</sup>Phasentransfer-Oxidation nach Grignardierung: Eine einfache Synthese γ,γ-disubstituierter γ-Butyrolactone aus γ-Butyrolacton (1987)

Lactones; XIII. Grignard Reaction Followed by Phase-Transfer Oxidation: A Convenient Synthesis of γ,γ-Disubstituted γ-Butyrolactones from γ-Butyrolactone Grignard Reaction of γ-butyrolactones, followed by oxidation of the resulting reaction mixture produces symmetrically γ,γ-dialkylared diarylated γ-butyrolactones. Phase transfer oxidation with potassium permanganate in benzene/water proves to be the best out of twelve examined oxidation methods. The synthesis is unsuccessful with sterically hindered or oxidizable Grignard reagents.
Connection rerouting in general-topology connection-oriented mobile networks (2002)

Connection rerouting is an important function for handoff processing in connection-oriented mobile communication networks. Several methods have been proposed for the connection rerouting, but they are lacking in generality and flexibility. We propose a general model of connection rerouting based on connection information. The generality and flexibility of the proposed method essentially come from the connection information.
Basiswissen Maschinenelemente (2014)

Nonetheless, the book covers all aspects of machine elements and tests the reader’s understanding with extensive exercises.
Submicron Structures, Electrospinning and Filters (2007)

Electrospun fibers have been used in high efficiency filters for over two decades.The electrospun fibers are responsible for better performance of the filters.In this work, experiments were done in which electrospun nanofibers were exposed to a stream of oil fog.The growth rate of drops, by coalescence of oil droplets on a single fiber, was followed using optical microscopy.Different mechanisms by which the aerosol droplets can be captured include: interception, Brownian motion of droplets, inertial impaction and vapor deposition by diffusion.A quantitative model for predicting the growth rate by coalescence was developed and tested.The drop growth mechanism on a nanofiber can be attributed to both interception and Brownian diffusion mechanism in the creeping flow conditions.The relative contribution by the individual mechanisms was estimated.Merging of growing drops on the fiber was modeled and experimentally observed.The experimental merging time for drops is close to that predicted.We have discovered a novel technique of forming polymer nanostructures on various substrates, which involves vaporizing cyanoacrylate monomer.Cyanoacrylate monomer vapor was collected on a solid surface and polymerized to form nanofibers. Tiny spots of initiator on the surface of a substrate and small monomer droplets in the monomer vapor appear to be required for the growth of the polycyanoacrylate nanofibers.Morphology and size of the structures can be controlled by varying temperature, amount of monomer, amount of initiator and setup parameters.The polycyanoacrylate nanofibers CHAPTER I
GPCR expression in tissues and cells: Are the optimal receptors being used as drug targets? (2011)

G-protein-coupled receptors [GPCRs, also known as 7-transmembrane (7-TM) receptors] comprise the largest family of membrane receptors in humans and other species and, in addition, represent the greatest number of current drug targets. In this article, we review methods to define GPCR expression and data indicating that individual cells express >100 different GPCRs. Results from studies that have quantified expression of these receptors lead us to conclude that the optimal GPCRs may not be currently used as therapeutic targets. We propose that studies of GPCR expression in individual cells will likely reveal new insights regarding cellular physiology and therapeutic approaches. Findings that define and characterize the most highly expressed GPCRs thus have important potential in terms of identifying new drug targets and novel therapies directed at a wide range of clinical disorders.
Architecture for an open source network tester (2013)

To make networks more reliable, enormous resources are poured into all phases of the network-equipment lifecycle. The process starts early in the design phase when simulation is used to verify the correctness of a design, and continues through manufacturing and perhaps months of rigorously trials. With over 7,000 Internet RFCs and hundreds of IEEE standards, a typical piece of networking equipment undergoes hundreds of conformance tests before being deployed. Finally, when deployed in a production network, the equipment is tested regularly. Throughout the process, a relentless battery of tests and measurement help ensure the correct operation of the equipment.
Kinetics of three lymphoscintigraphic agents in patients with cutaneous melanoma. (1998)

All three agents are acceptable for cutaneous lymphoscintigraphy, but reliable identification of sentinel nodes and their afferent lymph channels requires early imaging. Delayed imaging or localization alone is unreliable and may lead to incorrect identification of the sentinel node.
Laboratory formation of a scaled protostellar jet by coaligned poloidal magnetic field (2014)

Although bipolar jets are seen emerging from a wide variety of astrophysical systems, the issue of their formation and morphology beyond their launching is still under study. Our scaled laboratory experiments, representative of young stellar object outflows, reveal that stable and narrow collimation of the entire flow can result from the presence of a poloidal magnetic field whose strength is consistent with observations. The laboratory plasma becomes focused with an interior cavity. This gives rise to a standing conical shock from which the jet emerges. Following simulations of the process at the full astrophysical scale, we conclude that it can also explain recently discovered x-ray emission features observed in low-density regions at the base of protostellar jets, such as the well-studied jet HH 154.
An Enhanced Fuzzy Clustering and Expectation Maximization Framework based Matching Semantically Similar Sentences (2015)

Statistical measure of finding Similar Sentences using a novel Fuzzy clustering algorithm framework is developed which organizes text from one or more documents into different clusters. The traditional fuzzy clustering approaches are not applicable to sentence clustering because most sentence similarity measures do not represent sentences in a common metric space. An enhanced Fuzzy clustering algorithm is applied in the sentence of datasets to group the related sentences. Page Rank algorithm highlights the more relevant inter clusters which interprets the Page-Rank score of an object. Expectation- Maximization (EM) framework has been developed in order to predict the overlapping clusters of semantically related sentences. Quotations dataset and News article dataset empirically implies the Similarity measure of matching Semantically Similar Sentences in which our system out performs the baseline method and projection methods. Our proposed method performs 34% higher in similarity scoring of related sentences. It also analyzes the clustering performance in terms of Entropy and Purity which yields more Purity and less Entropy. Our Experimental results demonstrates that our method is capable of identifying the overlapping clusters of semantically related sentences, and can be used in a variety of text mining tasks.
Noise in measurements obtained by sampling (1992)

Simple signal processing tools are used to describe noise in sampled measurements. Particular attention is paid to aliasing and the modification of noise spectra by the sampling process. The principles discussed are applied to near-optimal measurements of DC and AC signals in noise, and to the measurement of noise power. Specific problems have been chosen to demonstrate novel approaches and to clarify situations where confusion has arisen. Examples include alternative definitions of equivalent noise bandwidth, the bandpass sampling theorem, quantization and dither, the variance in the mean of correlated measurements, the exploitation of anticorrelation in resonant transducers, the ideal averaging filter, the resolution of synchronous demodulators, and sampling demodulators.
Quantifying and mitigating turnover-induced knowledge loss (2016)

The utility of source code, as of other knowledge artifacts, is predicated on the existence of individuals skilled enough to derive value by using or improving it. Developers leaving a software project deprive the project of the knowledge of the decisions they have made. Previous research shows that the survivors and newcomers maintaining abandoned code have reduced productivity and are more likely to make mistakes. We focus on quantifying the extent of abandoned source files and adapt methods from financial risk analysis to assess the susceptibility of the project to developer turnover. In particular, we measure the historical loss distribution and find (1) that projects are susceptible to losses that are more than three times larger than the expected loss. Using historical simulations we find (2) that projects are susceptible to large losses that are over five times larger than the expected loss. We use Monte Carlo simulations of disaster loss scenarios and find (3) that simplistic estimates of the 'truck factor' exaggerate the potential for loss. To mitigate loss from developer turnover, we modify Cataldo et al.'s coordination requirements matrices. We find (4) that we can recommend the correct successor 34% to 48% of the time. We also find that having successors reduces the expected loss by as much as 15%. Our approach helps large projects assess the risk of turnover thereby making risk more transparent and manageable.
