Effective disaster recovery for edge computing against large-scale natural disasters (2020)

With the spread of the Internet of Things (IoT), edge computing (EC) has attracted renewed attention. EC places resources such as CPU and storage closer to the user than cloud computing (CC) to realize low-latency services and/or mitigate network congestion to a cloud. In a telecommunications carrier, resources are placed at telephone central offices (TCOs). At the same time, EC requires disaster recovery for large-scale natural disasters such as earthquakes and tsunami, as TCOs have been damaged by natural disasters in the past. In disaster recovery of CC, data stored in a cloud is backed up to another geographically separated cloud location to prevent data loss due to natural disasters. However, as video IoT which is one of the most popular use cases of EC contains a large amount of data, backing up all data to a cloud causes network congestion to the cloud. Therefore, one way to mitigate network congestion is to back up data utilizing edges (i.e., distributed TCOs). In this paper, we propose disaster recovery for data backup by selecting a data backup location from as many distributed TCOs as possible to mitigate network congestion in EC against large-scale natural disasters. Our proposed method efficiently utilizes resources to prevent data loss due to natural disasters.
Function of cGMP-Dependent Protein Kinases as Revealed by Gene Deletion (2005)

Over the past few years, a wealth of biochemical and functional data have been gathered on mammalian cGMP-dependent protein kinases (cGKs). In mammals, three different kinases are encoded by two genes. Mutant and chimeric cGK proteins generated by molecular biology techniques yielded important biochemical knowledge, such as the function of the NH(2)-terminal domains of cGKI and cGKII, the identity of the cGMP-binding sites of cGKI, and the substrate specificity of the enzymes. Genetic approaches have proven especially useful for the analysis of the biological functions of cGKs. Recently, some of the in vivo targets and mechanisms leading to changes in neuronal adaptation, smooth muscle relaxation and growth, intestinal water secretion, bone growth, renin secretion, and other important functions have been identified. These data show that cGKs are signaling molecules involved in many biological functions.

NOOSE - Networked Object-Oriented Security Examiner (2000)

NOOSE (Networked Object-Oriented Security Examiner) is a distributed vulnerability analysis system based on object modeling. It merges the functionality of host-based and network-based scanners, storing the results into several object classes. The remote agents are implemented as dynamically extended PERL agents. NOOSE is able to collect vulnerabilities from a variety of sources, including outputs from other vulnerability analysis programs (e.g., Muffet's CRACK), collecting information from systems that may or may not have cooperative agents on them. Communication is based on a secure, reliable datagram protocol implemented as a set of PERL object classes. Unlike some vulnerability systems, NOOSE presents the vulnerability information as an integrated database, showing how vulnerabilities may be combined into chains across multiple accounts and systems. It understands unconditional vulnerabilities (i.e., stack-overflow, password guessing) along with conditional (Trojan horse, rlogin, and NFS access). Conditional vulnerabilities gain limited or privileges if conditions exist, such as access to specific accounts. The information is presented as an object-oriented spreadsheet format, allowing the security manager to explore vulnerabilities at whim. Once complete, the vulnerability analysis can move both forwards and backwards interactively, showing both what a selected account can attack, as well as showing who can attack a selected account. Besides vulnerability analysis, the system can intelligently verify the installation of security patches, dynamically installing missing patches. NOOSE is therefore a flexible prototype, able to provide a subset of the functionality of COPS, SATAN and TRIPWIRE, yet because of the object model, be used for developing new paradigms, such as reacting to intrusions, information warfare, and survivability management systems.
Ion beam deposition of special film structures (1981)

The structure and properties of thin solid films deposited in vacuum can be influenced substantially if additional energy and momentum is provided to the growing layers by energetic, inert or film-forming species. Various ion beam configurations for investigating these effects are discussed. Recent results are presented in conjunction with the following special film structures: (1) epitaxial, graphoepitaxial, and hydrogenated amorphous silicon deposits; (2) hard and unusual films of carbon and of boron nitride. Though the basic structure of the latter films is quasi-amorphous, microcrystals of high-pressure phases could be detected. Further trends are outlined.
Cooperative source number estimation for cognitive radio networks (2014)

In this paper, we consider a cognitive radio (CR) network operating on a spectrum reserved for licensed primary user (PU) by employing spatial spectrum sharing (SS). When the secondary users (SUs) are equipped with multiple antennas, they can perform SS without interfering with the PU by orthogonalizing the secondary transmission with the interference channel . In order to avoid interference and to maximize the capacity of the secondary transmissions, it is essential that the SUs determine the dimension of the orthogonal transmission space. In CR networks where no cooperation is provided by the PU, this information can be obtained by estimating the number of primary transmit streams at the secondary terminals. We study this issue when the secondary network performs cooperative estimation by using the minimum description length (MDL) algorithm to obtain the independent estimates and propose a decision fusion rule which takes into account the estimation bias of MDL. We will show that the proposed method can outperform conventional decision fusion rule and that it provides additional protection for the PU in the case of estimation error.
An efficient design of embedded memories and their testability analysis using Markov chains (2003)

A design strategy for efficient and comprehensive random testing of embedded random-access memory (RAM), where the address, read/write, and data input lines are not directly controllable and the data output lines are not externally observable, is presented. Unlike conventional approaches which use a linear feedback shift register (LFSR) to generate a signature and a register to store the reference fault-free signature, this technique uses a testable design which both accelerates the test by a factor of 0.5 square root n in an n-bit RAM and improves the test reliability by eliminating the LFSR. The problem of memory initialization has been elegantly circumvented by using word-line flag registers. An in-depth and comprehensive analysis of the functional faults, such as stuck-at, coupling, and pattern-sensitive, is performed. The analysis shows that, in order to test a 1-Mb RAM for common functional faults, the technique needs only 1 s, as opposed to about an hour needed by the conventional random testing.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High performance digital multimeter with 'internal calibration' (2003)

An approach that allows a digital multimeter to be calibrated using a minimum number of external reference standards is described. The approach centers around an extremely linear and flexible A/D converter. The linearity of the converter gives the instrument the ability to accurately measure the ratio of two DC voltages, while the speed of the converter allows for an accurate internal DC to AC transfer. In addition to reduced calibration cost and complexity, the approach allows for correction of time and temperature changes of all but a few very stable reference components. The end result is a digital multimeter able to perform DC and low-frequency AC measurements with high accuracy, precision, and speed and without the usual high cost of maintaining such an instrument.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Mechanically Initiated Bark Growth in Celtis (1939)

While engaged during the spring of 1938 in making a vegetational survey of the Pere Marquette Wildlife Study Area for the Illinois State Natural History Survey, the author chanced to observe several examples of an odd growth phenomenon. The Pere Marquette Area is located on a point of land in Calhoun County, Illinois, at the juncture of the Illinois and Mississippi Rivers and consists entirely of river-bottom land which is for the most part wooded with typical river-bottom forest.
Color balancing for change detection in multitemporal images (2012)

Automatic color balancing approaches for different applications have been studied by different research communities in the past decade. However, in this paper we address color balancing for the purpose of change detection. Images of a scene taken at different times may have variations in lighting and structural content. For such multitemporal images, an ideal color correction approach should be effective at transferring the color palette of the source image to the target image for the unchanged areas while being able to transfer the global color characteristics for the changed area without creating visual artifacts. Towards this goal, we propose a new local color balancing approach that uses adaptive windowing. We evaluated the proposed method against other state-of-the-art ones using a database consisting of aerial image pairs. The test image pairs were taken at different times, under different lighting conditions, and with different scene geometries and camera positions. On this database, our proposed approach outperformed other state-of-the-art algorithms.
FANET: Smart city mobility off to a flying start with self‐organized drone‐based networks (2021)

Abstract Due to recent advancements in smart city traffic and transport monitoring industry 4.0 applications. Flying Ad‐Hoc Networks (FANETs) ability to cover geographically large areas, makes it a suitable technology to address the challenges faced during remote areas traffic monitoring. The implementation of drone based FANETs have several advantages in remote traffic monitoring, including free air‐to‐air drone assisted communication zone and smart surveillance and security. The drone‐based FANETs can be deployed within minutes without requiring physical infrastructure, making it suitable for mission critical applications in several areas of interests. Here a drone‐based FANETs application for smart city remote traffic monitoring is presented while addressing several challenges including coverage of larger geographical area and data communication links between FANETs nodes. A FANET‐inspired enhanced ACO algorithm that easily coped with drone assisted technology of FANETs is proposed to cover the large areas. Simulation results are presented to compare the proposed technique against different network lifetime and number of received packets. The presented results show that the proposed technique perform better compared to other state‐of‐the‐art techniques.

Postgenomic taxonomy of human ureaplasmas – a case study based on multiple gene sequences (2004)

In 2000, the full genome sequence of Ureaplasma parvum (previously known as Ureaplasma urealyticum) serovar 3 was released. In 2002, after prolonged debate, it was agreed that the former U. urealyticum should be divided into two species -- U. parvum and U. urealyticum. To provide additional support for this decision and improve our understanding of the relationship between these two species, the authors studied four 'core' genes or gene clusters in ATCC reference strains of all 14 serovars of U. parvum and U. urealyticum. These 'core' regions were the rRNA gene clusters, the EF-Tu genes (tuf), urease gene clusters and multiple-banded antigen genes (mba). The known U. parvum genome sequences (GenBank accession no. NC_002162) were used as reference. DNA insertions and deletions (indels) were found in all of the gene regions studied, except tuf, but they were found only between, not within, the two species. An incidental finding was that there was inter-copy heterogeneity for rRNA gene cluster sequences. Sequence analysis (sequence heterogeneity and especially indels) of all four selected targets consistently supported the separation of human ureaplasmas into two species. Except for multiple-banded antigen, there was less heterogeneity in amino acid sequences of proteins, between species, than in the nucleic acid sequences of the corresponding genes. The degrees of heterogeneity at the 5' end of the species-specific regions of multiple-banded antigen were almost identical for both amino acid and nucleotide sequences. Analysis of the authors' results provided an interesting case study to help resolve some common problems in the use of sequence data to infer phylogenetic relationships and support taxonomic changes. It is recommended that, to avoid confusion, the new nomenclature be used for human ureaplasmas in future publications.
An 8-Channel Transmit 32-Channel Receive 7T Head Coil for 1Tx and pTx Scanner Modes (2019)

In this work, a nested array of 8-transmit elements was developed and combined with a 32-channel receive array for imaging the human brain at 7T. This setup can be used in the single channel and parallel transmit mode of the Siemens 7T scanner. The transmit array was designed to make the setup less claustrophobic and provide an open feel, benefitting fMRI and patient studies. The transmit performance of this setup is presented here.

Resolution improvement in x-ray imaging with an energy-resolving detector (2017)

In x-ray imaging, improving spatial resolution is an important goal, but developing detectors with smaller pixels is technically challenging. We demonstrate a technique for improving the spatial resolution by utilizing the fact that linear attenuation coefficients of all substances within the human body can be expressed, to a good approximation, as a linear combination of two basis functions, or three if there is iodine contrast present in the image. When the x rays pass an interface parallel to the beam direction, the exponential attenuation law makes the linear attenuation coefficient measured by the detector a nonlinear combination of the linear attenuation coefficients on each side of the interface. This so-called nonlinear partial volume effect causes the spectral response to be dependent on the steepness of interfaces in the imaged volume. In this work, we show how this effect can be used to improve the spatial resolution in spectral projection x-ray imaging and quantify the achievable resolution improvement. We simulate x-ray transmission imaging of sharp and gradual changes in the projected path length of iodine contrast with an ideal energy-resolving photon-counting detector and demonstrate that the slope of the transition can be determined from the registered spectrum. We simulate piecewise-linear transitions and show that the algorithm is able to reproduce the transition profile on a subpixel scale. The FWHM resolution of the method is 5-30 % of the pixel width. The results show that an energy-resolving detector can be used to improve spatial resolution when imaging interfaces of highly attenuating objects.
Selection, biological properties and fitness of resistance‐breaking strains of <i>Tomato spotted wilt virus</i> in pepper (2003)

Summary In glasshouse tests, infective sap from plants infected with 17 different isolates of Tomato spotted wilt virus (TSWV) from four Australian states was inoculated to three Capsicum chinense accessions (PI 152225, PI 159236 and C00943) carrying single genes that confer hypersensitive resistance to TSWV. The normal response to inoculation was development of necrotic (hypersensitive) local lesions in inoculated leaves without systemic invasion, but 3/1386 infected plants also developed systemic susceptible reactions in addition to hypersensitive ones. Similarly when two isolates were inoculated to C. chinense backcross progeny plants, 1/72 developed systemic susceptible reactions in addition to localised hypersensitive ones. Using cultures from the four plants with susceptible reactions and following three to five further cycles of serial subculture in TSWV‐resistant C. chinense plants, four isolates were obtained that gave systemic susceptible type reactions in the three TSWV‐resistant accessions, and in TSWV‐resistant cultivated pepper ( C. annuum ). When three of these isolates were inoculated to tomato ( Lycopersicon esculentum ) breeding lines with single gene resistance to TSWV, resistance was not overcome. Similarly, none of the four isolates overcame partial resistance to TSWV in Lactuca virosa . When TSWV isolates were inoculated to tomato breeding lines carrying partial resistance from L. chilense , systemic infection developed which was sometimes followed by ‘recovery’. After four successive cycles of serial passage in susceptible cultivated pepper of a mixed culture of a resistance‐breaking isolate with the non resistance‐breaking isolate from which it came, the resistance‐breaking isolate remained competitive as both were still found. However, when the same resistance‐ breaking isolate was cultured alone, evidence of partial reversion to wild‐type behaviour was eventually obtained after five but not four cycles of long term serial subculture in susceptible pepper, as by then the culture had become a mixture of both types of strain. This work suggests that resistance‐breaking strains of TSWV that overcome single gene hypersensitive resistance in pepper are relatively stable. The findings have important implications for situations where resistant pepper cultivars are deployed widely in the field without taking other control measures as part of an integrated TSWV management strategy.
SAWFAST - A SAW diffraction channelizer (1986)

One important aspect of modern electronic warfare systems is the ability to sort signals according to their frequency. This paper describes a novel surface acoustic wave channelizer to perform this sorting at IF frequencies. The operating principles are analogous to an optical diffraction grating. Prototype devices that cover a 260 MHz bandwidth with a sidelobe rejection to about 40 dB are described.
New metabolites of the drug 5-aminosalicylic acid. I:<i>N</i>-β-D-glucopyranosyl-5-aminosalicylic acid (1989)

1. A new unstable metabolite of 5-aminosalicylic acid (5-ASA) was found in plasma from healthy volunteers dosed with 5-ASA i.v. 2. The metabolite was prepared by incubation of 5-ASA with rat liver homogenate, and isolated using preparative h.p.l.c. 3. The metabolite was identified as N-beta-D-glucopyranosyl-5-aminosalicylic acid by n.m.r. spectroscopy and by FAB mass spectrometry. 4. N-beta-D-Glucopyranosyl-5-ASA was formed non-enzymically from 5-ASA and glucose in phosphate buffer pH 7.4, and was unstable under weakly acidic conditions, decomposition increasing with temperature, i.e. decomposition was complete after 30 min at pH 5.0 and 23 degrees C.
