Arrhythmia classification using the RR-interval duration signal (2003)

In this paper we explore the RR-interval duration signal in classifying arrhythmias. Initially the RR-interval duration signal is extracted from the ECGs. Each RR interval is characterized using the MIT-BIH arrhythmia database annotation. We use a 3 RR interval sliding window, centered in the middle RR interval, to classify each beat using a rule-based approach. The rules are obtained from cardiologists and are related to the tachogram morphology in arrhythmic events. Classification is performed for five categories of arrhythmic heats. The classification system is tested using selected beats from the MIT-BIH database (30,000 annotated heats were used). We present results in terms of sensitivity, positive prediction and system's performance. The scores achieved indicate high performance (95.85%) for the classification of the different categories of arrhythmic beats.
Storage codes: Managing big data with small overheads (2013)

Erasure coding provides a mechanism to store data redundantly for fault-tolerance in a cost-effective manner. Recently, there has been a renewed interest in designing new erasure coding techniques with different desirable properties, including good repairability and degraded read performance, or efficient redundancy generation processes. Very often, these novel techniques exploit the computational resources available `in the network', i.e., leverage on storage units which are not passive entities supporting only read/write of data, but also can carry out some computations. This article accompanies an identically titled tutorial at the IEEE International Symposium on Network Coding (NetCod 2013), and portrays a big picture of some of the important processes within distributed storage systems, where erasure codes designed by explicitly taking into account the nuances of distributed storage systems can provide significant performance boosts.
Effect of Annealing in High-Tc Superconducting Y-Ba-Cu Oxide (1987)

Effect of annealing under various gas flow atmosphere on the crystal structure and electrical resistivity for the high- T c superconducting single phase in Y-Ba-Cu oxide system is investigated. When a specimen is annealed under a nitrogen or argon atmosphere, the unit cell dimensions in an orthorhombic cell change remarkably, and the superconducting properties are degraded.
Pubovaginal Sling Procedure for Stress Incontinence (1978)

Urinary stress incontinence associated with poor urethral sphincter function and indicated by a urethral pressure of less than 10 cm. water was treated in 52 cases with a pubovaginal autogenous fascial sling. No urethral sphincter function could be measured in 7 patients. Of these 52 patients 42 had undergone a previous operation for stress incontinence. The uninhibited detrusor dysfunction that accompanied the stress incontinence in 29 cases ceased after operation in 20 but persisted in 9. Postoperative urethral pressure measurements indicated that while the sling increased urethral pressure it did not cause an obstruction during voiding, since there was a measurable decrease in urethral pressure during a detrusor contraction. Urodynamic determination were useful in patient selection, in the adjustment of sling tension at operation and in the assessment of reasons for failure. A satisfactory result with good urinary control was obtained in 50 cases and the procedure was a failure in 2.
Visual phenomena induced by cosmic rays and accelerated particles (1972)

Experiments, conducted at cyclotrons together with observations by Apollo astronauts, suggest with little doubt that cosmic nuclei interacting with the visual apparatus cause the phenomenon of light flashes seen on translunar and transearth coast over the past four Apollo missions. Other experiments with high and low energy neutrons and a helium ion beam suggest that slow protons and helium ions with a stopping power greater than 10 to the 8th power eV/gram sq cm can cause the phenomenon in the dark adapted eye. It was demonstrated that charged particles induced by neutrons and helium ions can stimulate the visual apparatus. Some approaches to understanding the long term mission effects of galactic cosmic nuclei interacting with man and his nervous system are outlined.

Interconnect-aware high-level synthesis for low power (2003)

Interconnects (wires, buffers, clock distribution networks, multiplexers and buses) consume a significant fraction of total circuit power. In this work, we demonstrate the importance of optimizing on-chip interconnects for power during high-level synthesis. We present a methodology to integrate interconnect power optimization into high-level synthesis. Our binding algorithm not only reduces power consumption in functional units and registers in the resultant register-transfer level (RTL) architecture, but also optimizes interconnects for power. We take physical design information into account for this purpose. To estimate interconnect power consumption accurately for deep sub-micron (DSM) technologies, wire coupling capacitance is taken into. consideration. We observed that there is significant spurious (i.e., unnecessary) switching activity in the interconnects and propose techniques to reduce it. Compared to interconnect-unaware power-optimized circuits, our experimental results show that interconnect power can be reduced by 53.1% on an average, while reducing overall power by an average of 26.8% with 0.5% area overhead. Compared to area-optimized circuits, the interconnect power reduction is 72.9% and overall power reduction is 56.0% with 44.4% area overhead.
Effect of Physical Properties and Emulsification Conditions on the Microsphere Size Prepared Using a Solvent Extraction Process (2012)

Microspheres were prepared using a hydrocarbon-perfluorocarbon solvent extraction process. The effect of the physical properties and the emulsification conditions on the mean microsphere size was investigated. The viscosity of the dispersed and the continuous phase greatly affected the microsphere size. Smaller microspheres were produced at the same mixing intensity when the viscosity of the dispersed phase decreased. Increased continuous phase viscosity reduced the coalescenceof the droplets and hence smaller microspheres were produced. The mean microsphere size first decreased as the volume ratio of the dispersed phase to the continuous phase increased but upon further increase the mean microsphere size increased. The effect of the volume ratio on the microsphere size was linked to the surfactant concentration. The stability of the studied hydrocarbon-in-fluorocarbon emulsion is poor. One reason for the poor stability is the high density difference between the phases. The emulsion droplets were solidified by siphoning part of the emulsion in the fresh continuous phase, which extracted the solvent from the dispersed phase. The effect of emulsion transfer time between the emulsification and solidification steps on the particle size was studied but no significant effect was observedduring the controlled time interval.
The Polyphenol Pterostilbene Ameliorates the Myopathic Phenotype of Collagen VI Deficient Mice via Autophagy Induction (2020)

The induction of autophagy, the catabolic pathway by which damaged or unnecessary cellular components are subjected to lysosome-mediated degradation and recycling, is impaired in Collagen VI (COL6) null mice and COL6-related myopathies. This autophagic impairment causes an accumulation of dysfunctional mitochondria, which in turn leads to myofiber degeneration. Our previous work showed that reactivation of autophagy in COL6-related myopathies is beneficial for muscle structure and function both in the animal model and in patients. Here we show that pterostilbene (Pt)-a non-toxic polyphenol, chemically similar to resveratrol but with a higher bioavailability and metabolic stability-strongly promotes <i>in vivo</i> autophagic flux in the skeletal muscle of both wild-type and COL6 null mice. Reactivation of autophagy in COL6-deficient muscles was also paralleled by several beneficial effects, including significantly decreased incidence of spontaneous apoptosis, recovery of ultrastructural defects and muscle remodeling. These findings point at Pt as an effective autophagy-inducing nutraceutical for skeletal muscle with great potential in counteracting the major pathogenic hallmarks of COL6-related myopathies, a valuable feature that may be also beneficial in other muscle pathologies characterized by defective regulation of the autophagic machinery.
Attractive telepresence communication with movable and touchable display robot (2015)

We propose an active display robot for tele-communication system combining 3-axis display arm manually controlled by touch input, and automatically controlled by human tracking. This system is designed to present distance change behavior between user and robot by implementing two types of user interaction during communication; 1) Providing robot's movement to follow the user who is far from or going to pass by the display robot, 2) providing touchable display to activate and manipulate the direction of the display during the user is sited in front of the display system. Both local and remote users use the same system to communicate, make user's attention to distanced user via the system. Manipulating the movable part of the display by the movement of the finger of the user's touch makes the display correspond to user's intention and attention. There are two advantages of the movable display by the operation of the user's touch. One is to enhance remote communication by making the display arm moving with touch operation. Second is to enable the transmission of non-verbal information through the operation of the display. We designed hardware and software associated with user behavior and user input via the display. It is expected that the system will solve that the problem of misunderstanding of remote device operation, then it contribute to intuitive operation. In order to evaluate how this system does contribute to intuitive operation, we conducted an assessment experiment by using Questionnaire of Likert scale and interview. We verified that the display can move in response to operator's touch input contribute to intuitive experience.

Improved Sensitivity and Resolution in 1H−13C NMR Experiments of RNA (1998)

NMR studies of the structure and dynamics in RNA are greatly facilitated by the use of 13C-labeled molecules and 1H−13C correlation experiments. We demonstrate here that spin-state selective 13C frequency editing yields greatly improved sensitivity and resolution in 1H−13C correlation spectra of RNA. A sensitivity enhanced version of the previously introduced TROSY sequence (Pervushin et al., Proc. Natl. Acad. Sci. U.S.A. 1997, 94, 12366−12371) is proposed, which offers a √2 signal enhancement. When compared to a sensitivity enhanced HSQC sequence an up to 3-fold increase in both the sensitivity and resolution is observed for the base carbons in a 15% 13C-labeled 33-mer RNA at a magnetic field strength of 14.1 T. This increase results from the relaxation interference between the 13C chemical shielding anisotropy (CSA) and the 1H−13C dipolar interaction, as well as the simultaneous detection of 1H and 13C steady-state polarizations. Simulations indicate that the enhancement effect is maximal at currently available magnetic field strengths (≤18.8 T). It is further shown that the recording of a pair of complementary TROSY experiments, denoted H(α)- and H(β)-TROSY allows the accurate measurement of 1H−13C one-bond coupling constants from the cross-peak positions in the two spectra. An extension of the TROSY sequence is presented for recording high resolution 3D 13C-edited NOESY spectra.
UV‐B irradiation differentially regulates terpene synthases and terpene content of peach (2017)

Plants generate protective molecules in response to ultraviolet (UV) light. In laboratory experiments, 48 h UV-B irradiation of peach fruits and leaves reduced the flavour-related monoterpene linalool by 60%. No isoprene was detected, but other terpenoids increased significantly, including a threefold accumulation of the sesquiterpene (E,E)-α-farnesene, which was also increased by jasmonic acid treatment. RNA sequencing revealed altered transcript levels for two terpene synthases (TPSs): PpTPS1, a TPS-g subfamily member, decreased by 86% and PpTPS2, a TPS-b subfamily member, increased 80-fold. Heterologous expression in Escherichia coli and transient overexpression in tobacco and peach fruits showed PpTPS1 was localized in plastids and associated with production of linalool, while PpTPS2 was responsible for (E,E)-α-farnesene biosynthesis in the cytoplasm. Candidate regulatory genes for these responses were identified. Commercial peach production in Asia involves fruit bagging to maintain marketable yield and quality. TPS gene expression and volatile terpenoid production in field experiments, using bags transmitting high UV-B radiation, showed similar effects on peach volatiles to those from laboratory experiments. Bags transmitting less UV-B light ameliorated the reduction in the flavour volatile linalool, indicating that flavour components of peach fruits can be modulated by selecting an appropriate source of environmental screening material.
All one needs to know about fog computing and related edge computing paradigms: A complete survey (2019)

With the Internet of Things (IoT) becoming part of our daily life and our environment, we expect rapid growth in the number of connected devices. IoT is expected to connect billions of devices and humans to bring promising advantages for us. With this growth, fog computing, along with its related edge computing paradigms, such as multi-access edge computing (MEC) and cloudlet, are seen as promising solutions for handling the large volume of security-critical and time-sensitive data that is being produced by the IoT. In this paper, we first provide a tutorial on fog computing and its related computing paradigms, including their similarities and differences. Next, we provide a taxonomy of research topics in fog computing, and through a comprehensive survey, we summarize and categorize the efforts on fog computing and its related computing paradigms. Finally, we provide challenges and future directions for research in fog computing.
Variable-Valued Logic: System VL1 (1974)

The paper defines the concept of a variable-valued logic (VL) system and discusses in detail one specific VL system called VL1. The main motivation for the development of the VL system concept is to construct a well-defined, general formal system unifying various combinatorial problems and adequate, in particular, for problems of 'learning from examples' (problems which are of special interest to areas of pattern recognition and machine intelligence).
An implementation of multichannel multi-interface MANET for fire engines and experiments with WINDS satellite mobile earth station (2016)

We propose a novel communication system for an emergency fire response team, which provides Internet service on the way to and in the disaster area. The system is composed of a multi-interface mobile ad-hoc network (MANET) router, a Global Positioning System (GPS) receiver, and two Wi-Fi interfaces with directional antennas, which can be easily attached to the roof of a vehicle. The front-side Wi-Fi interface of the vehicle is operated in the infrastructure mode, and the rear-side interface is operated in the access point mode. Different channels are assigned to each AP interface of the vehicles. Infrastructure-mode Wi-Fi interfaces automatically scan and connect to an appropriate AP interface and create MANET links. Some experiments using this wireless system with the WINDS satellite mobile earth station and nine fire engines were conducted in Ebetsu, Hokkaido. We measured the TCP throughput and confirmed that a throughput of more than 10 Mbps was able to be obtained by most of the node pairs. In addition, high-vision video streaming was able to be successfully transmitted to the streaming server on the Internet through MANET and satellite communication links while they were platooning.

Diagonal transformations in quadrangulations of surfaces (1996)

In this paper, it will be shown that any two bipartite quadrangulations of any closed surface are transformed into each other by two kinds of transformations, called the diagonal slide and the diagonal rotation, up to homeomorphism, if they have the same and sufficiently large number of vertices. © 1996 John Wiley & Sons, Inc.
Direct Imaging of Integer and Half-Integer Josephson Vortices in High-TcGrain Boundaries (1996)

We have used a high-resolution scanning SQUID microscope to directly image conventional ( $h/2e$) Josephson vortices trapped in grain boundaries, and half-integer ( $h/4e$) Josephson vortices trapped at the tricrystal point, of the high- ${T}_{c}$ superconductor ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{7\ensuremath{-}\ensuremath{\delta}}$ grown on tricrystal substrates of SrTi${\mathrm{O}}_{3}$. Our observation of the half-integer vortex at the tricrystal point is the first direct demonstration of the positive paramagnetic Meissner effect in a polycrystalline high- ${T}_{c}$ film. In addition, our images provide the first direct measurement of the Josephson penetration depth.

Compounds controlling the ethylene receptor (1999)

Many organic compounds interact with the ethylene receptor and diffuse free after different periods of time. Some are agonists and mimic ethylene, and some are antagonists, which prevent ethylene action by blocking the receptor. Some of the antagonists have proven useful in scientific studies, and some promise to be commercially important in protecting against ethylene. The times that different compounds remain bound may be important clues to how ethylene transmits its signal to the signal transduction pathway. Ethylene diffuses from the site with a t 1/2 of 2n10 minutes and is an active compound. For 2,5-Norbornadiene (2,5-NBD) and some other strained olefins that block ethylene action, the half diffusion time is 3n6 h. For other more strained compounds (cyclopropenes) the half diffusion time is estimated to be 7n12 days; they block ethylene action during this time. The time of diffusion from the receptor appears to be the major difference between compounds that block the receptor and those that are active. It is suggested that this time constant may be the controlling factor in ethylene action.
