Managing Intellectual Property in a Music Fruition Environment (2015)

With the advent of the digital age and the spread of portable digital audio players, interest in software and hardware tools that can help producers and distributors enhance and revive their catalogue of music has progressively increased. One of the main concerns of major labels is how to prevent file sharing. An innovative approach that couples reviving catalogues with support for rights management could provide an experience of multimedia content in which users select multiple media streams on the fly in a fully synchronized environment. Because this kind of user experience can't be reconstructed from the single original streams, illegal copying would be intrinsically discouraged. In this article, the authors propose an approach to encode contents and build advanced multimodal interfaces that protect intellectual property. As a case study, they use the IEEE 1599--an international standard for music description.
Noninvasive magnetic detection of cardiac mechanical activity: Theory (1980)

Because the magnetic susceptibility of the heart and the intracardiac blood is substantially greater than that of the surrounding lung tissue, the periodic redistribution of blood and tissue during the cardiac cycle will alter an externally applied magnetic field. These magnetic field changes can be detected by a magnetometer outside the body and have been termed magnetic susceptibility plethysmography (MSPG) signals. This paper presents a theoretical analysis of the MSPG technique. A single moving sphere model is used to explain the susceptibility induced field changes and the detection of the MSPG signals. The susceptibility distribution within the thorax and a more detailed model of the heart are then used to predict the MSPG waveform. Several other contributions to the MSPG signal are analyzed. This model has demonstrated that the time dependence of certain MSPG components closely resembles that of the total heart volume while other components have waveforms similar to the displacement of the cardiac center of mass. The magnitude and direction of the MSPG field has been shown to depend on the location of the field point, the volume change of the heart, and the motion of the heart's center of mass. It has also been shown that 90% of more of the MSPG signal recorded near the heart but outside the body will be produced by cardiac volume changes. For these reasons, the MSPG technique may provide a noninvasive method of measuring changes both in total cardiac volume and in the position of the cardiac center of mass throughout the cardiac cycle.
Two-Dimensional Metal–Organic Surfaces for Efficient Hydrogen Evolution from Water (2014)

Hydrogen production through the reduction of water has emerged as an important strategy for the storage of renewable energy in chemical bonds. One attractive scenario for the construction of efficient devices for electrochemical splitting of water requires the attachment of stable and active hydrogen evolving catalysts to electrode surfaces, which remains a significant challenge. We demonstrate here the successful integration of cobalt dithiolene catalysts into a metal-organic surface to generate very active electrocatalytic cathode materials for hydrogen generation from water. These surfaces display high catalyst loadings and remarkable stability even under very acidic aqueous solutions.
Acetate Intolerance in Chronic Uremic Patients (1979)

The metabolic effects of an acute acetate load have been investigated in chronic uremic patients and in controls. The decay rate of blood acetate levels was significantly lower in patients than in controls. Higher levels of blood acetoacetate and 2-oxoglutarate and plasma triglycerides were observed in the patients after the load. No difference was detectable in plasma levels of unesterified fatty acids and cholesterol between the two groups of subjects. Acetate oxidation in citric acid cycle may be reduced in uremia owing to a lack of coenzyme A. These observations raise the possibility that chronic acetate administration with the dialysate induces hypertriglyceridemia and accelerates the development of atherosclerosis in hemodialysis patients.

The FMN to Heme Electron Transfer in Cytochrome P450BM-3 (1999)

The crystal structure of the complex between the heme and FMN-containing domains of Bacillus megaterium cytochrome P450BM-3 (Sevrioukova, I. F., Li, H., Zhang, H., Peterson, J. A., and Poulos, T. L. (1999) Proc. Natl. Acad. Sci. U. S. A. 96, 1863-1868) indicates that the proximal side of the heme domain molecule is the docking site for the FMN domain and that the Pro(382)-Gln(387) peptide may provide an electron transfer (ET) path from the FMN to the heme iron. In order to evaluate whether ET complexes formed in solution by the heme and FMN domains are structurally relevant to that seen in the crystal structure, we utilized site-directed mutagenesis to introduce Cys residues at positions 104 and 387, which are sites of close contact between the domains in the crystal structure and at position 372 as a control. Cys residues were modified with a bulky sulfhydryl reagent, 1-dimethylaminonaphthalene-5-sulfonate-L-cystine (dansylcystine (DC)), to prevent the FMN domain from binding at the site seen in the crystal structure. The DC modification of Cys(372) and Cys(387) resulted in a 2-fold decrease in the rates of interdomain ET in the reconstituted system consisting of the separate heme and FMN domains and had no effect on heme reduction in the intact heme/FMN-binding fragment of P450BM-3. DC modification of Cys(104) caused a 10-20-fold decrease in the interdomain ET reaction rate in both the reconstituted system and the intact heme/FMN domain. This indicates that the proximal side of the heme domain molecule represents the FMN domain binding site in both the crystallized and solution complexes, with the area around residue 104 being the most critical for the redox partner docking.
Hydrophobically Associating Polymers As Rheology Modifiers (1997)

Hydrophobically associating water-soluble polymers are essentially hydrophilic polymer chains containing a small number of strongly hydrophobic groups, distributed or located at some priviledged sites on the chains. In aqueous media, hydrophobic units tend to associate in order to minimize their exposure to water, leading to reversible intra- and intermolecular hydrophobic junction networks, at even very low polymer concentrations. Such temporary networks influence strongly the linear and nonlinear rheological properties of the solutions and make such polymers candidates as rheology modifiers in aqueous-based formulations such as drilling fluids. In this paper, we present the main rheological characteristics of hydrophobically associating water-soluble polymers, the influence of the presence of a surfactant on their rheological properties and the rheology of solutions containing a mixture of associating and non-associating water-soluble polymers.
Substrate Specificity and Mode of Action of the Lipase of Thermophilic Fungus<i>Humicola lanuginosa</i>S-38 (1973)

Substrate specificity of the lipase of thermophilic fungus, Humicola lanuginosa S–38, was investigated. It was found that the lipolytic activity was greatly influenced by the structure of both fatty acid and alcohol moieties of the substrate. It was concluded that the hydrolysis of both water soluble and water insoluble ester was catalyzed by the Humicola lipase itself. The Humicola lipase showed no positional specificity and split ester bonds on all positions of triolein at about the same rate. Both palmitic acid (α) and linoleic acid (β) ester bonds of phosphatidyl-ethanolamine were split indicating no positional specificity of fatty acid ester bonds. From above results, it was made clear that mode of action of Humicola lipase on triolein and on phosphatidyl-ethanolamine is identical. The Humicola lipase had no activity of lipoprotein lipase.

High-speed microfabricated silicon turbomachinery and fluid film bearings (2005)

A single-crystal silicon micromachined air turbine supported on gas-lubricated bearings has been operated in a controlled and sustained manner at rotational speeds greater than 1 million revolutions per minute, with mechanical power levels approaching 5 W. The device is formed from a fusion bonded stack of five silicon wafers individually patterned on both sides using deep reactive ion etching (DRIE). It consists of a single stage radial inflow turbine on a 4.2-mm diameter rotor that is supported on externally pressurized hydrostatic journal and thrust bearings. This work presents the design, fabrication, and testing of the first microfabricated rotors to operate at circumferential tip speeds up to 300 m/s, on the order of conventional high performance turbomachinery. Successful operation of this device motivates the use of silicon micromachined high-speed rotating machinery for power microelectromechanical systems (MEMS) applications such as portable energy conversion, micropropulsion, and microfluidic pumping and cooling.
The Current Study of Cyclo-tetrasaccharide Focused on the Synthesizing System from Starch. (2002)

酵素的に合成されたオリゴ糖は数多くあるが、澱粉から合成される非還元性グルコオリゴ糖は、かなり少数である。そのような糖質の例として、トレハロースやシクロデキストリンがある。環状四糖 (CTS; cyclo {→6)-α-D-glcp-(1→3)-α-D-glcp-(1→6)-α-D-glcp-(1→3)-α-D-glcp-(1→}) もまた、非還元性グルコオリゴ糖の一種である。この環状オリゴ糖の澱粉からの生成系が、最近、Bacillus globisporus C11株に見出され、二つの酵素が関与したCTS生成機構およびそれらの遺伝子構造が相次いで報告された。これらにより、CTSの工業的製造の可能性とCTSの合成および輸送に関与する遺伝子クラスターの存在が示された。本レビューでは、澱粉からの環状四糖の酵素的生成系を中心に、最新の研究結果について記述する。

A systolic parallel Laplacian pyramid image compression architecture (2015)

The Laplacian pyramid image compression (LPIC) algorithm can be used to preprocess an image for efficient compression, particularly for extraterrestrial exploration projects.LPIC involves a two-dimensional convolution which lends itself to a parallel architecture implementation..This thesis develops the design of a systolic parallel architecture for the algorithm.The LPIC algorithm is implemented in a special purpose integrated chip design.The archticture for the system is discussed, as well as the individual registers used for the multiplication.The registers are constructed with a single-clock multiplier/accumulator circuit.Simulations show that the bit level circuit could operate at 50 MHz and is logically correct.A 16-bit register has been completely designed and submitted for fabrication.The modules for the convolution have also been designed.
Some Improvements in Quartz Crystal Circuit Elements (1934)

The characteristics of the Y-cut quartz crystal plate are discussed. It is shown that by rotating a plate about the X axis special orientations are found for which the frequency spectrum is simplified, the temperature coefficient of frequency is reduced practically to zero and the amount of power that can be controlled without fracture of the crystal is increased. These improvements are obtained without sacrificing the advantages of the Y cut plate, i.e., activity and the possibility of rigid clamping in the holder.
Cylinder3D: An Effective 3D Framework for Driving-scene LiDAR Semantic Segmentation (2020)

State-of-the-art methods for large-scale driving-scene LiDAR semantic segmentation often project and process the point clouds in the 2D space. The projection methods includes spherical projection, bird-eye view projection, etc. Although this process makes the point cloud suitable for the 2D CNN-based networks, it inevitably alters and abandons the 3D topology and geometric relations. A straightforward solution to tackle the issue of 3D-to-2D projection is to keep the 3D representation and process the points in the 3D space. In this work, we first perform an in-depth analysis for different representations and backbones in 2D and 3D spaces, and reveal the effectiveness of 3D representations and networks on LiDAR segmentation. Then, we develop a 3D cylinder partition and a 3D cylinder convolution based framework, termed as Cylinder3D, which exploits the 3D topology relations and structures of driving-scene point clouds. Moreover, a dimension-decomposition based context modeling module is introduced to explore the high-rank context information in point clouds in a progressive manner. We evaluate the proposed model on a large-scale driving-scene dataset, i.e. SematicKITTI. Our method achieves state-of-the-art performance and outperforms existing methods by 6% in terms of mIoU.
Logistic applications with wireless sensor networks (2010)

Wireless Sensor Networks have been deployed for environmental monitoring, home automation, and advanced metering application fields among others. Only few examples of monitoring cargo transports by Wireless Sensor Networks have been reported on. The authors have deployed mobile Wireless Sensor Networks in a cargo container on a trans-atlantic cargo vessel as well as on a lorry to monitor the transport conditions inside the container. This submission reports on the experiences gained from those particular deployments and the open research issues for mobile Wireless Sensor Networks for logistics.
RSSI-Based Indoor Localization and Identification for ZigBee Wireless Sensor Networks in Smart Homes (2018)

Location-based services have increased in popularity in recent years and can be fruitfully exploited in the field of smart homes, opening the doors to a wide range of personalized services. In this context, radio technology can be widely employed since, other than connecting devices in the home system, it offers solutions for the user localization issue without the need of any extra device. Techniques based on received signal strength indicator (RSSI) are often used, relying on fingerprinting or proximity algorithms. In this paper, a novel RSSI-based fingerprinting approach for room-level localization is presented: it is a threshold algorithm based on receiver operating characteristic analysis. Moreover, the actual user location is estimated from his/her interaction with the home system devices deployed in the house: if the home environment is inhabited by more than one person, it becomes of utmost importance the identification of who is actually interacting with a given device. A proximity method is exploited for this purpose. Tests have been carried out to characterize the approach, particularly, the effects of RSSI samples, number and position, of the anchor nodes have been analyzed. Finally, some considerations about power consumption of the mobile node have been presented.
Membrane estrogen receptor-α levels predict estrogen-induced ERK1/2 activation in MCF-7 cells (2004)

Our results suggest that the levels of mER-alpha play a role in the temporal coordination of phosphorylation/dephosphorylation events for the ERKs in breast cancer cells, and that these signaling differences can be correlated to previously demonstrated differences in E2-induced cell proliferation outcomes in these cell types.
Treatment of hyperuricemia in gout: current therapeutic options, latest developments and clinical implications (2016)

Despite being the most common type of inflammatory arthritis, gout is often poorly managed. Except for febuxostat and pegloticase, research in new therapeutic agents for the management of hyperuricemia in gout remained insufficient for several decades. With emerging evidence of possible roles of hyperuricemia in cardiometabolic comorbidities, as well as more convincing evidence regarding poor outcomes (e.g. disability, recurrent hospital admissions) in patients with uncontrolled gout, several agents are current under development. Increasing knowledge regarding renal urate transporters has resulted in the development of new generation uricosurics such as lesinurad and arhalofenate. This review aims at discussing current therapeutic strategies for gout, as well as their limitations and the possible role of emerging agents in the chronic management of hyperuricemia in gout. Drugs in phases I and II of development will be discussed, along with new agents and therapeutic classes, such as purine nucleoside phosphorylase inhibitors and dual-action drugs. These new developments are encouraging, and will hopefully contribute to a more adequate management of hyperuricemia in gout.
Studies on the in vitro interactions of cimetidine with commercial antacid preparations and chemically pure components. (1984)

Studies of the in vitro binding of cimetidine to commercial antacid preparations such as colloidal aluminium hydroxide-magnesium hydroxide, aluminium hydroxide-calcium carbonate and the chemical pure components Al(OH)3, Mg(OH)2 or Al2O3 showed no adsorption of cimetidine at cimetidine to antacid ratios employed in clinical practice. Small degrees of binding were observed with two silicate containing antacids (21.4 +/- 0.5 mumol/g and 12.3 +/- 1.9 mumol/g).
A Trinocular Vision Probe for Sculptured Surface Measurements (2004)

Reverse engineering of free-form surfaces is one of the most challenging technologies in advanced manufactu- ring. The vision system with CCD cameras possesses many advantages. To avoid possible mismatch in binocular systems a line structured light trinocular vision probe for sculptured surface measurements is developed. It distinguishes itself by high efficiency, high accuracy and reliability, as well as applicability for on-line measurement of complicated sculptured surfaces. The working principle and problems related to system optimization, camera calibration, sampling strategy, feature extraction, image matching and data reconstruction are discussed in detail in the paper. Experiments show that the trinocular probe enhances both accuracy and reliability of measurement in comparison with binocular one. An accuracy of 0.02 mm was achieved in the first prototype developed.
Observations on overlap: findings and implications for automatic processing of multi-party conversation (2001)

We examine the distribution of overlapping speech in different corpora of natural multi-party conversations, including two types of meetings, and two corpora of telephone conversations. Analyses are based on forced alignment and speech recognition using an identical recognizer across tasks. Three results are discussed. First, all corpora show high overall rates of overlap, with similar rates for meetings and telephone conversations. Second, speech recognition performance in non-overlapped regions of meetings is no worse than that in single-channel telephone conversations, while recognition in overlap regions degrades considerably. Finally, interrupt locations are associated with endpoints of word-level events in a speaker’s turn, including backchannels, discourse markers, and disfluencies. Results suggest that overlap is an important inherent characteristic of conversational speech that should not be ignored; on the contrary, it should be jointly modeled with acoustic and language model information in machine processing of conversation.
A Family of Human RNA-binding Proteins Related to theDrosophila Bruno Translational Regulator (2000)

The post-transcriptional regulation of gene expression by RNA-binding proteins is an important element in controlling both normal cell functions and animal development. The diverse roles are demonstrated by the Elav family of RNA-binding proteins, where various members have been shown to regulate several processes involving mRNA. We have identified another family of RNA-binding proteins distantly related to the Elav family but closely related to Bruno, a translational regulator in Drosophila melanogaster. In humans, six Bruno-like genes have been identified, whereas other species such as Drosophila, Xenopus laevis, and Caenorhabditis elegans have at least two members of this family, and related genes have also been detected in plants and ascidians. The human BRUNOL2 and BRUNOL3 are 92% identical in the RNA-binding domains, although the BRUNOL2 gene is expressed ubiquitously whereas BRUNOL3 is expressed predominantly in the heart, muscle, and nervous system. Both of these proteins bind the same target RNA, the Bruno response element. The RNA-binding domain that recognizes the Bruno response element is composed of two consecutive RNA recognition motifs at the amino terminus of vertebrate Bruno protein. The possible involvement of the Bruno family of proteins in the CUG repeat expansion disease myotonic dystrophy is discussed.
Distribution of tissue factor pathway inhibitor in normal and malignant human tissues. (1993)

Specific antibodies to tissue factor pathway inhibitor (TFPI) were used in immunohistochemical procedures to determine the distribution of TFPI in normal and neoplastic human tissues. TFPI was restricted to megakaryocytes and the endothelium of the microvasculature in normal and abnormal tissues, but was not found in the endothelium of larger vessels or in hepatocytes. TFPI was also detected in macrophages in the villi of term placenta. Tumor-associated macrophages in several types of malignancy that we have shown previously to express a complete tissue factor-initiated pathway of coagulation and thrombin generation also manifested TFPI. By contrast, malignant cells in small cell carcinoma of the lung, renal cell carcinoma, and malignant melanoma that we have shown previously to express coagulation factors together with tumor cell-associated fibrin formation failed to stain for TFPI. We postulate that TFPI may be lacking from the latter malignancies because of the absence of the appropriately configured tissue factor-factor VIIa-factor Xa complex required for TFPI binding.
