CCIoT-CMfg: Cloud Computing and Internet of Things-Based Cloud Manufacturing Service System (2014)

Recently, Internet of Things (IoT) and cloud computing (CC) have been widely studied and applied in many fields, as they can provide a new method for intelligent perception and connection from M2M (including man-to-man, man-to-machine, and machine-to-machine), and on-demand use and efficient sharing of resources, respectively. In order to realize the full sharing, free circulation, on-demand use, and optimal allocation of various manufacturing resources and capabilities, the applications of the technologies of IoT and CC in manufacturing are investigated in this paper first. Then, a CC- and IoT-based cloud manufacturing (CMfg) service system (i.e., CCIoT-CMfg) and its architecture are proposed, and the relationship among CMfg, IoT, and CC is analyzed. The technology system for realizing the CCIoT-CMfg is established. Finally, the advantages, challenges, and future works for the application and implementation of CCIoT-CMfg are discussed.
Superhydrophobic Covalent Organic Frameworks Prepared via Pore Surface Modifications for Functional Coatings under Harsh Conditions (2019)

Covalent organic frameworks (COFs) have been widely used in catalysis, energy storage, environmental protection, and separation. However, they require a long assembly period (∼3 days) and complex synthesis conditions; differences in water resistance have restricted their overall versatility. In this paper, the preparation of COF-DhaTab was optimized, and this process can be easily performed in air. Thus, it is feasible for the scale-up of COF-DhaTab in the near future. The superhydrophobic properties of COF-DhaTab (water contact angle, >150°) can be created by regulating the wettability of COF-DhaTab by grafting fluoride. When the grafting degree of fluoride increased to 4.32%, the water contact angle of COFs increased from 0° to more than 150°. The grafted COFs are termed COF-DhaTab fluoride (COF-DTF). The chemically modified COF-DhaTab maintains its original porosity and crystallinity. The superhydrophobic COF-DTF can be applied to various substrates, for example, foam, fabric, and glass. These all exhibit outstanding water repellency, self-healing, and excellent self-cleaning. Importantly, the coating maintains its original superhydrophobicity even under extremely acidic/basic conditions (pH = 1-14) and toward boiling water (100 °C). Furthermore, COF-DTF displays long-term stability and is easily scaled. It is a promising and practical candidate for hydrophobic modifications to various substrates.
Application of inertial navigation systems to geodetic postion and gravity vector survey (1978)

Inertial navigation systems are mechanized so as to measure the change in geodetic latitude and longitude and geometric height relative to a specified earth's reference spheroid or datum. Since this is the basic task of geodetic survey, conventional inertial navigation systems, which have been used for decades for missile and aircraft navigation, are in essence low-quality survey systems. Navigation errors result, in inertial systems, from the angular orientation error of the accelerometer-sensing axes relative to the reference surface, the scale factor error, and noise that exists in the measurements themselves. One of the principal noise sources contaminating the specific force measurements made by the accelerometers is the anomalous behavior of the gravity vector relative to the reference spheroid assumed that is not accounted for by a gravity model contained in the system computer, Errors induced in the system-computed velocity and position by the gravity disturbance, observed by the use of appropriate reference sensors, serve as one means for determining the anomalous behavior of the gravity vector along a survey vehicle's travel route. Additionally, if the inertial system is brought to rest, the deviation of the gravity vector from the computer gravity model can be directly determined from the accelerometer measurements. Stopping of a survey vehicle carrying an inertial navigation system also allows the error in the system-computed velocity to be observable to high precision. Stopping of the vehicle at points whose geodetic and astronomic positions and gravity value have been determined by independent means provides observations of the error in system-computed geodetic position and the system-estimated anomalous gravity vector. This tutorial paper discusses the manner in which the observations of the error in the systemcomputed velocity and position and the gravity vector are employed in realizing a practical inertial surveying system of high accuracy. System performance, assuming the application of optimal filtering and smoothing techniques is also indicated.
Sodium Acts as a Potassium Analog on Gastric H,K-ATPase (1995)

The effects of Na+ on gastric H,K-ATPase were investigated using leaky and ion-tight H,K-ATPase vesicles. Na+ activated the total ATPase activity in the absence of K+, reaching levels of 15% relative to those in the presence of K+. The Na+ activation, which takes place at the luminal side of the membrane, depended on the ATP concentration and the type of buffer used. The steady-state ATP phosphorylation level, studied with leaky vesicles, was reduced by Na+ due to both activation of the dephosphorylation reaction and a shift to E2 in the E1<==>E2 equilibrium. By studying this equilibrium in ion-tight H,K-ATPase vesicles, it was found that Na+ drives the enzyme via a cytosolic site to the nonphosphorylating E2 conformation. No H(+)-like properties of cytosolic Na+ could be detected. We therefore conclude that Na+ behaves like K+ rather than like H+ in the H,K-ATPase reaction.
Retinoic acid receptor- and retinoid X receptor-selective retinoids activate signaling pathways that converge on AP-1 and inhibit squamous differentiation in human bronchial epithelial cells. (1996)

Human bronchial epithelial (HBE) cells undergo squamous differentiation in response to a variety of conditions in tissue culture, and retinoid treatment has been shown to reverse this process. Retinoids mediate their effects through the retinoic acid and retinoid X nuclear receptors (RAR and RXR, respectively), which form RAR-RXR heterodimers, RXR homodimers, and heterodimers of RXR and certain orphan receptors. These receptor dimers bind to distinct response elements, activating separate pathways. In this study, we investigated the roles of RAR and RXR signaling pathways in the inhibition of HBE squamous differentiation. After induction of squamous differentiation by confluent growth, HBE cells were treated with retinoids that selectively activate RARs (E-4-[2-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthaienyl)-1- propenyl] benzoic acid), RXRs (4-[1-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydro-2-naphthyl)ethenyl]benzoic acid), or both RARs and RXRs (9-c/s retinoic acid). These retinoids inhibited the mRNA expression of the squamous differentiation markers transglutaminase type I, involucrin, keratin 5, and keratin 13, suggesting that inhibition of HBE squamous differentiation could be mediated by activation of either RAR or RXR signaling pathways. We examined the role of AP-1 as a potential effector of these retinoid pathways. AP-1 transcriptional activity was reduced markedly by these retinoids, and a concomitant, but proportionally smaller, reduction in AP-1 DNA binding was observed. Furthermore, treatment of squamous HBE cells with the retinoid SR11238, which inhibited AP-1 without activating retinoid receptor transcriptional properties, reduced the expression of transglutaminase type I and involucrin. These findings support the hypothesis that, in HBE cells, RAR and RXR signaling pathways inhibit AP-1 transcriptional activity, and this contributes to retinoid-induced reversal of HBE squamous differentiation.
Estimating Oceanic Mixed-Layer Depth from Internal Wave Evolution Observed from Radarsat-1 SAR (2000)

One Radarsat-1 SAR image acquired on 31 July 1998 was used to study internal wave characteristics off the northeastern coast of the United States. The image showed several trains of internal waves, with several wave packets in each train. By assuming that the local semidiurnal tide period is the generating source for these waves, and by measuring the distance between the wave packets, we were able to derive the group velocity of the internal waves from synthetic aperture radar (SAR) images directly. If we also assume that the ocean is a two-layer finite depth model, we can then derive the mixed-layer depth by matching the group velocity measured from the SAR image with that simulated by the model. Results show reasonably good agreement between in situ conductivity-temperature-depth data and expendable bathythermographic climatology measurements.
SUBCUTANEOUS AND INTRADERMAL VACCINATION WITH ASIAN INFLUENZA VACCINE (1957)

Since the isolation of the Asian influenza virus in May, 1957,<sup>1</sup>there has been a tremendous marshalling of public health services, research and laboratory teams, and production facilities. Further, as one of the phenomena of our times, we have seen in the lay press immediate and broad coverage of all aspects of an anticipated influenza epidemic, of vaccine production and distribution difficulties, and of the uncertainties of dosage schedules and efficacy of the vaccine. As is natural, an enlightened public has sought immunization at a time when supplies of the vaccine are insufficient to meet the demand and, indeed, at a time when the physician has only the most general statements for guidance in his immunization procedures. Under these circumstances it is understandable that, with previous experience with influenza vaccine of the ordinary type as precedent,<sup>2</sup>attempts have been made to stretch the limited supply of the Asian

ZIGZAG: an efficient peer-to-peer scheme for media streaming (2003)

A peer-to-peer technique called ZIGZAG for single-source media streaming is designed . ZIGZAG allows the media server to distribute content to many clients by organizing them into an appropriate tree rooted at the server. This application-layer multicast tree has a height logarithmic with the number of clients and a node degree bounded by a constant. This helps reduce the number of processing hops on the delivery path to a client while avoiding network bottleneck. Consequently, the end-to-end delay is kept small. Although one could build a tree satisfying such properties easily, an efficient control protocol between the nodes must be in place to maintain the tree under the effects of network dynamics and unpredictable client behaviors. ZIGZAG handles such situations gracefully requiring a constant amortized control overhead. Especially, failure recovery can be done regionally with little impact on the existing clients and mostly no burden on the server.
Nitric oxide mediates behavioral signs of neuropathic pain in an experimental rat model (1998)

This study was conducted to determine whether nitric oxide (NO) is involved in the maintenance of behavioral signs of neuropathic pain induced by tightly ligating the left L5 and L6 spinal nerves. Neuropathic rats showed behavioral signs representing mechanical allodynia, cold allodynia and cold-stress exacerbated ongoing pain. Mechanical allodynia was suppressed by Nomega-nitro-L-arginine methyl ester (L-NAME; 200, 100, 50, 10 microM/kg, i.p.), a nitric oxide synthase inhibitor, in a dose-dependent manner. Cold allodynia and cold-stress exacerbated ongoing pain was also attenuated by L-NAME. Neither Nomega-nitro-D-arginine methyl ester (D-NAME; 200 microM/kg) nor saline changed any of the neuropathic pain behaviors. These results suggested that NO plays an important role in the maintenance of the behavioral signs of neuropathic pain and is involved in common steps in the maintenance of the different modalities of pain such as mechanical allodynia and cold allodynia.
A MapReduce workflow system for architecting scientific data intensive applications (2011)

MapReduce is promising for developing both scalable business and scientific data intensive applications. However, there are few existing scientific workflow systems which can benefit from the MapReduce programming model. We propose a workflow system for integrating structure, and orchestrating MapReduce jobs for scientific data intensive workflows. The system consists of a simple workflow design C++ API, a job scheduler, and a runtime support system for Hadoop or Sector/Sphere frameworks. A climate satellite data intensive processing and analysis application is developed as a use case and an evaluation for the workflow system. The evaluation shows that it is possible to make the steps in the climate data intensive application automatically from data gridding to complex data analysis using the workflow system. The performance of the climate analysis application is significantly improved by the enabled MapReduce workflow system compared with the sequential embarrassing parallel methods. The overhead of the workflow system is negligible. However, the graphic user interface is still under development for the workflow system.
Scattering by an Inhomogeneous Solid. II. The Correlation Function and Its Application (1957)

Experiments on the angular intensity distribution of x-rays scattered by porous materials (hole structures) in the range of small angles are described. It is shown that the scattering can be characterized by an exponential correlation function in the case of a distribution of holes of random shape and size in solid; a theoretical derivation of the exponential function is given for this case. When the correlation function is an exponential, the rule holds that the reciprocal square root of the scattered intensity is a linear function of the square of the scattering angle. The specific surface of the material is determined by the slope of this straight line. Specific surfaces of a number of compositions are calculated from their experimental correlation functions and compared to surfaces based on adsorption measurements.
Cloning and characterization of PTPL1, a protein tyrosine phosphatase with similarities to cytoskeletal-associated proteins. (1994)

A novel cytoplasmic protein tyrosine phosphatase (PTP), PTPL1, was identified and cloned using a polymerase chain reaction-based approach. Overlapping cDNA clones encompass an open reading frame of 7398 base pairs, predicting a protein of 2466 amino acid residues with a molecular mass of 275 kDa. PTPL1 has a wide tissue distribution, a 9.5-kilobase transcript being expressed in most tissues. Peptide antisera against PTPL1 specifically precipitate a protein with an apparent mass of 250 kDa. PTPL1 has a PTP domain located in the COOH terminus, and the protein was shown to dephosphorylate 32P-labeled myelin basic protein. In the non-enzymatic part of PTPL1, three different structural motifs can be identified. Two of these are often found in proteins at the interface between the plasma membrane and the cytoskeleton, i.e. a 300-amino acid domain with similarity to the band 4.1 superfamily, and a region consisting of five GLGF repeats, an 80-amino acid repeat found in a variety of cytoskeleton-associated proteins. In addition to these structures PTPL1 has a region that fulfills the criteria for a leucine zipper motif. PTPL1 is the hitherto largest PTP identified and the only one known which contains a leucine zipper motif.
Determination of ionized calcium in serum by use of an lon-selective electrode. I. Determination of normal values under physiologic conditions, with comments on the effects of food ingestion and hyperventilation. (1972)

Ionized calcium was determined in serum from 84 normal individuals by using a flow-through calcium-selective electrode operated at 37°C. The mean value was 1.08 ± 0.06 (2 SD) mmol/liter. The relationship of serum ionized calcium concentration to other serum constituents was examined. The effects of hyperventilation and food ingestion on ionized calcium were studied. Respiratory alkalosis, induced by hyperventilation, caused a decrease in ionized calcium of 0.05 ± 0.02 (2 SD) mmol/liter per 0.1 unit increase in pH. In contrast, the metabolic alkalosis induced by food ingestion caused a decrease in ionized calcium of 0105 ± 0.025 (2 SD) mmol/liter per 0.1 unit increase in pH.
The Curvelet Transform (2010)

Multiresolution methods are deeply related to image processing, biological and computer vision, and scientific computing. The curvelet transform is a multiscale directional transform that allows an almost optimal nonadaptive sparse representation of objects with edges. It has generated increasing interest in the community of applied mathematics and signal processing over the years. In this article, we present a review on the curvelet transform, including its history beginning from wavelets, its logical relationship to other multiresolution multidirectional methods like contourlets and shearlets, its basic theory and discrete algorithm. Further, we consider recent applications in image/video processing, seismic exploration, fluid mechanics, simulation of partial different equations, and compressed sensing.
X-ray scattering as a probe for warm dense mixtures and high-pressure miscibility (2011)

We demonstrate the abilities of elastic x-ray scattering to yield information on dense matter with multiple ion species and on the microscopic mixing in dense materials. Based on partial structure factors from ab initio simulations, a novel approach for the elastic scattering feature is applied to dense hydrogen-beryllium and hydrogen-helium mixtures. The scattering signal differs significantly between single species, real microscopic mixtures, and two separate fluids in the scattering volume.
Protecting Your Software Updates (2012)

As described in many blog posts and the scientific literature, exploits for software vulnerabilities are often engineered on the basis of patches, which often involves the manual or automated identification of vulnerable code. The authors evaluate how this identification can be automated with the most frequently referenced diffing tools, demonstrating that for certain types of patches, these tools are indeed effective attacker tools. But they also demonstrate that by using binary code diversification, the effectiveness of the tools can be diminished severely, thus severely closing the attacker's window of opportunity.
Physicochemical and Microstructural Properties of Polymerized Whey Protein Encapsulated 3,3′-Diindolylmethane Nanoparticles (2019)

The fat-soluble antioxidant 3,3'-diindolylmethane (DIM), is a natural phytochemical found in <i>Brassica</i> vegetables, such as cabbage, broccoli, and Brussels sprouts. The stability of this compound is a major challenge for its applications. Polymerized whey protein (PWP)-based DIM nanoparticles were prepared at different mass ratios of protein and DIM by mixing PWP and DIM followed by ultrasound treatment for 4 min. All the nanoparticles were studied for particle size, zeta potential, rheological and microstructural properties, and storage stability. The mean particle size of the PWP-based nanoparticles was significantly increased (<i>p</i> < 0.05) by the addition of DIM at different mass ratios, ranging from 241.33 ± 14.82 to 270.57 ± 15.28 nm. Zeta potential values of all nanoparticles were highly negative (greater than ±30 mV), suggesting a stable solution due its electrostatic repulsive forces. All samples exhibited shear thinning behavior (<i>n</i> < 1), fitted with Sisko model (R² > 0.997). Fourier Transform Infrared (FTIR)spectra revealed that the secondary structure was changed and the absorption intensity for hydrogen bonding got stronger by further incorporating DIM into PWP. Transmission electronic microscopy (TEM) images showed spherical and smooth surface shape of the PWP-based nanoparticles. DIM encapsulated by PWP showed enhanced stability at 4, 37 and 55 °C for 15 days evidenced by changes in mean particle size and color (a*-value and b*-value) compared with control (DIM only). In conclusion, the polymerized whey protein based 3,3'-diindolylmethane nanoparticles are stable and the encapsulation may protect the core material from oxidation.
