Blockchain-Based Data Sharing System for AI-Powered Network Operations (2018)

The explosive development of mobile communications and networking has led to the creation of an extremely complex system, which is difficult to manage. Hence, we propose an AI-powered network framework that uses AI technologies to operate the network automatically. However, due to the separation between different mobile network operators, data barriers between diverse operators become bottlenecks to exploit the full power of AI. In this paper, we establish a mutual trust data sharing framework to break these data barriers. The framework is based on the distributed and temper-proof attributes of blockchain. We implement a prototype based on Hyperledger Fabric. The proposed system combines supervision and fine-grained data access control based on smart contracts, which provides a secure and trustless environment for data sharing. We further compare our system with existing data sharing schemes, and we find that our system provides a better functionality.
Activation energy for thermal donor formation in silicon (1987)

Czochralski silicon samples have been heated for increasing periods of time at temperatures of 395, 415, 450, 475, and 490 °C. At each stage infrared spectra of the electronic absorption of thermal donors TD2–TD9 were obtained with the samples at 4.2 K. The data for all the thermal donor centers can be presented on one universal plot, provided the concentration and time axes are simply scaled by factors that depend only on the temperature of heating. It is implied that the rate of formation of each center is limited by the same mechanism. An activation energy of 1.7±0.1 eV is determined for these processes.
Adult neurogenesis modifies excitability of the dentate gyrus (2013)

Adult-born dentate granule neurons contribute to memory encoding functions of the dentate gyrus (DG) such as pattern separation. However, local circuit-mechanisms by which adult-born neurons partake in this process are poorly understood. Computational, neuroanatomical and electrophysiological studies suggest that sparseness of activation in the granule cell layer (GCL) is conducive for pattern separation. A sparse coding scheme is thought to facilitate the distribution of similar entorhinal inputs across the GCL to decorrelate overlapping representations and minimize interference. Here we used fast voltage-sensitive dye (VSD) imaging combined with laser photostimulation and electrical stimulation to examine how selectively increasing adult DG neurogenesis influences local circuit activity and excitability. We show that DG of mice with more adult-born neurons exhibits decreased strength of neuronal activation and more restricted excitation spread in GCL while maintaining effective output to CA3c. Conversely, blockade of adult hippocampal neurogenesis changed excitability of the DG in the opposite direction. Analysis of GABAergic inhibition onto mature dentate granule neurons in the DG of mice with more adult-born neurons shows a modest readjustment of perisomatic inhibitory synaptic gain without changes in overall inhibitory tone, presynaptic properties or GABAergic innervation pattern. Retroviral labeling of connectivity in mice with more adult-born neurons showed increased number of excitatory synaptic contacts of adult-born neurons onto hilar interneurons. Together, these studies demonstrate that adult hippocampal neurogenesis modifies excitability of mature dentate granule neurons and that this non-cell autonomous effect may be mediated by local circuit mechanisms such as excitatory drive onto hilar interneurons. Modulation of DG excitability by adult-born dentate granule neurons may enhance sparse coding in the GCL to influence pattern separation.
Skin irritancy from propylene glycol (1984)

Two sensitive methods for the assessment of skin irritancy reactions to propylene glycol (PG) have been used: laser Doppler flowmetry in man for erythema and skin fold thickness measurements in man, guinea pigs and rabbits for edema. Single (open and occlusive) and repeated (open) exposures were used. Trafuril was used as positive control for the flowmetric studies. In man an increased blood flow was recorded only when PG was applied under occlusion. A statistically significant increase in skin fold thickness was observed from day 7 in the guinea pig, but not in man (daily exposures for 36 days). It is concluded that occlusion seems to be a crucial factor and that skin fold thickness measurements in guinea pigs and rabbits is a useful, complementary method for the detection and prediction of marginal irritants.
Matrix-assisted laser desorption/ionization mass spectrometry of carbohydrates (1999)

This review describes the application of matrix-assisted laser desorption/ionization (MALDI) mass spectrometry to carbohydrate analysis and covers the period 1991-1998. The technique is particularly valuable for carbohydrates because it enables underivatised, as well as derivatised compounds to be examined. The various MALDI matrices that have been used for carbohydrate analysis are described, and the use of derivatization for improving mass spectral detection limits is also discussed. Methods for sample preparation and for extracting carbohydrates from biological media prior to mass spectrometric analysis are compared with emphasis on highly sensitive mass spectrometric methods. Quantitative aspects of MALDI are covered with respect to the relationship between signal strength and both mass and compound structure. The value of mass measurements by MALDI to provide a carbohydrate composition is stressed, together with the ability of the technique to provide fragmentation spectra. The use of in-source and post-source decay and collision-induced fragmentation in this context is described with emphasis on ions that provide information on the linkage and branching patterns of carbohydrates. The use of MALDI mass spectrometry, linked with exoglycosidase sequencing, is described for N-linked glycans derived from glycoproteins, and methods for the analysis of O-linked glycans are also covered. The review ends with a description of various applications of the technique to carbohydrates found as constituents of glycoproteins, bacterial glycolipids, sphingolipids, and glycolipid anchors.
Efficient Aromatization of 4,5-Dihydro-3(2<i>H</i>)-Pyridazinones Substituted at 5 Position by Using Anhydrous Copper (II) Chloride (2000)

Abstract An efficient conversion of 5-substituted-4,5-dihydro-3(2H)-pyridazinones into their corresponding dehydrogenated derivatives was achieved by treatment with anhydrous copper(II) chloride in acetonitrile.
Towards efficient search on unstructured data (2007)

Applications that create and consume unstructured data have grown both in scale of storage requirements and complexity of search primitives. We consider two such applications: exhaustive search and integration of structured and unstructured data. Current block-based storage systems are either incapable or inefficient to address the challenges bought forth by the above applications. We propose a storage framework to efficiently store and search unstructured and structured data while controlling storage management costs. Experimental results based on our prototype show that the proposed system can provide impressive performance and feature benefits.
Compact modeling for application-specific high-sigma worst case (2013)

A high-sigma corner model derived from Monte Carlo simulation with a novel sampling algorithm is presented. Compared with the traditional Monte Carlo simulation approach, the simulation effort and computational resource is greatly reduced. This methodology can be applied to create application-specific corner model for different design spec leading to more competitive designs.
De vuelta al laberinto: España y la cultura del Barroco, una propuesta de modernidad ampliada (2008)

Este estudio muestra la notable herencia del Barroco reverdecido en la actualidad en el movimiento neobarroco. El punto de partida de esta «vuelta al laberinto» es la constatacion de la permanencia de ciertos nucleos barrocos y neobarrocos en la cultura contemporanea, tanto en lo que refiere a sus discursos como en sus producciones y estilos de vida. Esta vinculacion de la cultura barroca con la tardomodernidad global se explora a traves del auge del cuerpo, de la imagen y de la representacion «encamada», asi como de la creacion arquitectonica. Se pretende promover una reflexion sobre lo barroco como herencia relevante para tener una vision mas profunda y comprensiva de la cultura espanola actual y, por extension, de como ambas culturas (la barroca y la tardomodema) pueden articularse en una propuesta de modernidad ampliada.
Urinary Kallikrein Excretion in Hypertensive Man (1974)

Urinary kallikrein excretion was measured by a radiochemical esterolytic assay in patients with essential hypertension or primary aldosteronism. Patients with essential hypertension excreted significantly less ( P < 0.001) kallikrein than did normal subjects when they were allowed an ad libitum sodium intake or given 259 mEq sodium/day. When sodium intake was changed from ad libitum to 9 mEq/day, kallikrein excretion increased in the majority of patients with essential hypertension, but it remained significantly less ( P < 0.001) than that in normal subjects; however, aldosterone excretion was similar in both groups. Fludrocortisone, 0.5 mg/day for 10 days, increased kallikrein excretion in three patients with essential hypertension. In patients with primary aldosteronism, mean kallikrein excretion was sevenfold higher ( P < 0.001) than that in patients with essential hypertension; kallikrein excretion remained unchanged when dietary sodium was altered, but it was decreased by treatment with spironolactone. Mean kallikrein excretion in patients with primary aldosteronism was also significantly higher ( P < 0.001) than that in a normotensive control population. The results show that kallikrein excretion reflects the effective level of circulating sodium-retaining steroid in patients with primary aldosteronism but suggest that it is relatively unresponsive to endogenous sodium-retaining steroid in patients with essential hypertension. The data raise the possibility that the kallikrein-kinin system is of pathogenetic significance in human hypertensive disease.
Frequency-tuned salient region detection (2009)

Detection of visually salient image regions is useful for applications like object segmentation, adaptive compression, and object recognition. In this paper, we introduce a method for salient region detection that outputs full resolution saliency maps with well-defined boundaries of salient objects. These boundaries are preserved by retaining substantially more frequency content from the original image than other existing techniques. Our method exploits features of color and luminance, is simple to implement, and is computationally efficient. We compare our algorithm to five state-of-the-art salient region detection methods with a frequency domain analysis, ground truth, and a salient object segmentation application. Our method outperforms the five algorithms both on the ground-truth evaluation and on the segmentation task by achieving both higher precision and better recall.
Solution Structure of [Me‐<scp>L</scp>‐Leu<sup>7</sup>]Didemnin B Determined by NMR Spectroscopy and Refined by MD Calculation (1990)

Abstract Several homo‐ and heteronuclear two‐dimensional NMR techniques were used to assign all H‐ and C‐resonances of the two conformers A and B of [7‐( N ‐methyl‐ L ‐leucine)]didemnin B. Didemnine is a biologically highly active cytostaticum and immunosuppressivum. The assignment of the aliphatic C‐atoms were done by the inverse H,C‐COSY with TOCSY transfer which connects complete proton spin systems and represents them on C‐atoms. The structure of both conformers ( A and B ) in (D 6 )DMSO solution was derived from homo‐ and heteronuclear couplings ( J ), temperature dependencies of NH protons, and NOE effects. Distances determined from the latter were used for refinements by restrained MD calculations using the GROMOS program. The solution structure of [Me‐ L ‐Leu 7 ]didemnin B ( A and B ) was compared to that of didemnin B. The backbone structure of the macrocyclic ring and of the linear side‐chain moiety are very similar in conformer A and didemnin B , though the Ist 1 ‐Hip 2 region of the ring is slightly ex tended in conformer A . This may be caused by the influence of the Me‐ L ‐Leu 7 residue in A and may be responsible for its reduced biological activity in comparison to didemnin B . The more weakly populated conformer B exhibits a βVI turn in the linear side‐chain moiety.

Design and implementation of a SMIL player (1999)

Synchronized Multimedia Integration Language (SMIL) is a recommendation developed by the Synchronized Multimedia Working Group in the World Wide Web Consortium (W3C). SMIL is a simple and standard way to specify a timeline based synchronized multimedia presentation over the Internet. It is a declarative authoring language based on Extensible Markup Language (XML) to define language-specific data types and tags. A SMIL player schedules presentation in a SMIL file, and retrieves media objects on the Web using URLs described in the file. The SMIL file is a plain text file and can be edited using a simple text editor. We present the approaches of implementing a SMIL player within the desktop system constraints. The reference implementation is a Java applet, which follows a platform-neutral programming paradigm and makes use of Java Media Framework (JMF), The applet can run in any main stream web browser.
Metal-Metal Oxide and Metal Oxide Electrodes as pH Sensors (1989)

The pH is one of the most important parameters for char-acterizing the chemical properties of an aqueous solution. The glass eiectrode is by far the most commonly used pH sensor. The determination of pH in special situations, e.g., in vivo applications where the fragility of the glass electrode is a draw-back, requires pH sensors that can easily be miniaturized and built into physically rugged sleeves. Also, for other applications where the volume of solution is very restricted miniaturization of pH sensors is very important. The glass electrode does not respond properly to pH in some corrosive environments (e.g., in hydrogen fluoride [HF] solutions). At present, among alternatives to the hydrogen-selective glass electrode group of sensors, potentiometric metal-metal oxide pH sensors respond to pH, ideally due to an equilibrium involving the metal and its oxide. In the case of metal oxide electrodes, the metal is not involved in the potential-determining reaction. This distinction is of course not clear in many cases because the mechanism giving the pH response is not always unequivocal.
V(D)J recombination: evidence that a replicative mechanism is not required. (1991)

We examined a series of extrachromosomal DNA substrates for V(D)J recombination under replicating and nonreplicating conditions. Complete and partial replications were examined by monitoring the loss of prokaryote-specific adenine methylation at 14 to 22 MboI-DpnI restriction sites (GATC) on the substrates. Some of these sites are within 2 bases of the signal sequence ends. We found that neither coding joint nor signal joint formation requires substrate replication. After ruling out replication as a substrate requirement, we determined whether replication had any effect on the efficiency of V(D)J recombination. Quantitation of V(D)J recombination efficiency on nonreplicating substrates requires some method of monitoring the entry of substrate molecules into the cells. We devised such a method by monitoring DNA repair of substrates into which we had substituted deoxyuridine for 10 to 20% of the thymidine nucleotides in the DNA. The substrates which enter the lymphoid cells were repaired efficiently in vivo by the eukaryotic uracil DNA repair system. Upon plasmid harvest, we distinguished repaired (entered) from unrepaired (not entered) plasmids by cleaving unrepaired molecules with uracil DNA glycoylase and Escherichia coli endonuclease IV in vitro. This method of monitoring DNA entry does not appear to underestimate or overestimate the amount of DNA entry. By using this method, we found no significant quantitative effect of DNA replication on V(D)J recombination efficiency.

γ-radiation-induced attenuation in photonic crystal fibre (2002)

Results are presented of what, to the knowledge of the authors, is the first study of the sensitivity of a photonic crystal fibre (PCF) under steady-state gamma irradiation. Radiation-induced attenuation of a PCF has been measured at 1.55 µm. This new type of fibre showed a higher attenuation level than a standard monomode fibre but had a fast kinetic of recovery after irradiation.
Degradation and induction specificity in actinomycetes that degrade p-nitrophenol (1993)

We have isolated two soil bacteria (identified as Arthrobacter aurescens TW17 and Nocardia sp. strain TW2) capable of degrading p-nitrophenol (PNP) and numerous other phenolic compounds. A. aurescens TW17 contains a large plasmid which correlated with the PNP degradation phenotype. Degradation of PNP by A. aurescens TW17 was induced by preexposure to PNP, 4-nitrocatechol, 3-methyl-4-nitrophenol, or m-nitrophenol, whereas PNP degradation by Nocardia sp. strain TW2 was induced by PNP, 4-nitrocatechol, phenol, p-cresol, or m-nitrophenol. A. aurescens TW17 initially degraded PNP to hydroquinone and nitrite. Nocardia sp. strain TW2 initially converted PNP to hydroquinone or 4-nitrocatechol, depending upon the inducing compound.
Aluminoborate Glass‐Ceramics with Low Thermal Expansivity (1990)

The synthesis and properties of calcium, strontium, and barium aluminoborate glass‐ceramics are described in this paper. Glass powder compacts near the RO‐Al 2 O 3 ‐B 2 O 3 stoichiometry were sintered and crystallized below 1000°C to form dense glass‐ceramics containing RAI 2 B 2 O 7 as the principal phase. Thermal expansion coefficients as low as 6 × 10 −7 /°C, 15 × 10 −7 /°C, and 23 × 10 −7 /°C were measured on SrAl 2 B 2 O 7 , CaAl 2 B 2 O 7 , and BaAl 2 B 2 O 7 glass‐ceramics, respectively. Two forms of the ultra‐low‐expansion SrAl 2 B 2 O 7 were not previously reported in the literature and were indexed as cubic and hexagonal crystals. The unique radial spherulitic interbladed microstructures and other important properties of these glass‐generated ceramics are also revealed.

Random mappings designed for commercial search engines (2015)

We give a practical random mapping that takes any set of documents represented as vectors in Euclidean space and then maps them to a sparse subset of the Hamming cube while retaining ordering of inter-vector inner products. Once represented in the sparse space, it is natural to index documents using commercial text-based search engines which are specialized to take advantage of this sparse and discrete structure for large-scale document retrieval. We give a theoretical analysis of the mapping scheme, characterizing exact asymptotic behavior and also giving non-asymptotic bounds which we verify through numerical simulations. We balance the theoretical treatment with several practical considerations; these allow substantial speed up of the method. We further illustrate the use of this method on search over two real data sets: a corpus of images represented by their color histograms, and a corpus of daily stock market index values.
Components development for plasma blasting technology (2002)

Plasma blasting technology (PBT), a method to generate explosions from electrical discharges, has been demonstrated to be a clean and well-controlled way to fracture rock and concrete. Laboratory systems and field prototypes were built for the purpose of proving the feasibility of the PBT process and for establishing energy requirements for various blasting applications. In order to further advance the state of the technology, a program was initiated by Noranda to develop and test long-lasting components for PBT with commercial applications in sight. A blasting test bench was built in order to allow repetitive testing (>200 shots/day) of critical components such as the blasting electrode, cables, and switch. The program led to successful testing of electrodes (>500 shots life) and flexible power-delivery cables (>1000 shots life). The next step of the development will focus on the adaptation of these components to various industrial platforms.
Spatiotemporal reservoir resampling for real-time ray tracing with dynamic direct lighting (2020)

Efficiently rendering direct lighting from millions of dynamic light sources using Monte Carlo integration remains a challenging problem, even for off-line rendering systems. We introduce a new algorithm---ReSTIR---that renders such lighting interactively, at high quality, and without needing to maintain complex data structures. We repeatedly resample a set of candidate light samples and apply further spatial and temporal resampling to leverage information from relevant nearby samples. We derive an unbiased Monte Carlo estimator for this approach, and show that it achieves equal-error 6×-60× faster than state-of-the-art methods. A biased estimator reduces noise further and is 35×-65× faster, at the cost of some energy loss. We implemented our approach on the GPU, rendering complex scenes containing up to 3.4 million dynamic, emissive triangles in under 50 ms per frame while tracing at most 8 rays per pixel.
The Occurrence of Rare Cancers in U.S. Adults, 1995–2004 (2010)

Collectively, rare tumors account for a sizable portion of adult cancers, and disproportionately affect some demographic groups. Maturing population-based cancer surveillance data can be an important source for research on rare cancers, potentially leading to a greater understanding of these cancers and eventually to improved treatment, control, and prevention.
Monoclonal Antibodies Against Human Haptoglobin (1989)

Three monoclonal antibodies: 2.36.71.41, 7.60.66.55, and 18.4.40. 80 to human haptoglobin 2-1 were produced, purified and characterized. The affinity constants ranged within 0.3-2.4 x 10(8) M-1. The monoclonal antibodies 7.60.66.55 and 18.4.40.80 reacted with beta subunit of haptoglobin, showed similar epitope affinities and epitope densities on main haptoglobin types. However, the epitope on the haptoglobin molecule for the monoclonal antibody 18.4.40.80 occupied somewhat more surface than that for the antibody 7.60.66.55. The monoclonal antibody 2.36.71.41 was able to bind both alpha and beta chains of haptoglobin. In ELISA affinity reactions this antibody achieved with haptoglobin 2-2 the plateau phase at absorbance values 15% higher than with haptoglobin 2-1, and 60% higher than with haptoglobin 1-1. End-point titration of the monoclonal antibody 2.36.71.41 against three haptoglobin types showed differences in titer, indicating distinct epitope densities.
