Threshold-based processing for continuous query in wireless sensor networks

This paper presents a threshold based query processing method for continuous data gathering in sensor networks. The method is based on the flexible setting of thresholds and the analysis on the content to be sent over the network. Thresholds represent the accuracy requirement of the application issuing the queries. Thus at each single sensor node, instead of direct delivery of each result data, data communication is needed only when the current data is out of the range constrained by the thresholds. A series of static and dynamic algorithms are proposed for the flexible setting of threshold values. The performance of the proposed algorithms shows that the proposed methods can achieve better performance than without performing the optimization.
Acute Q fever pneumonia: a review of 80 hospitalized patients.

STUDY OBJECTIVES To emphasize epidemiologic, clinical, or radiologic characteristics whose detection could lead to an early diagnosis and to enhance therapeutic efficacy. PATIENTS Eighty hospitalized patients from 1982 to 1996. DESIGN The diagnosis of Q fever infection was serologically confirmed in all the patients (phase II Coxiella burnetii antibody) using the complement fixation test and/or the indirect immunofluorescence antibody test. RESULTS Patients from rural and urban areas were noted in the same proportion; however, the usual epidemiologic factors such as contact with cats or farm animals were found in 40% of the patients. Mean age+/-SD was 49+/-20 years, and there was a higher sex ratio of male to female patients (1:3.44). We found a specific seasonal distribution since 80% of the cases occurred between February and May. Delay before referring to hospital was 8.2+/-7.8 days, while 69.3% of the patients received an antibiotic treatment that was mainly penicillin or cephalosporin. The dominant clinical features were dry cough and high fever, as the maximal temperature reached more then 40 degrees C in 58% of the patients. Digestive symptoms were rare. WBC count remained within normal range in 80% of the cases with a low proportion of lymphocytes in half of the patients, and the sedimentation rate was usually elevated (55+/-34 mm). Altered liver function consisted more frequently in an elevated level of alkaline phosphatase (70% of the cases) than transaminases, while hyponatremia was frequently mentioned (28.2% of the patients). We found radiologic evidence of unique lobar or segmental alveolar opacity involving more likely the lower lobes in 55 patients, and multiple or interstitial opacities in the others. Chest radiographs were considered normal in eight patients. The clinical response was favorable in all the patients with a reduction in fever 4.8+/-3.9 days after the start of treatment with the second antibiotic that included mainly erythromycin or quinolones, and chest radiographs returned to normal in 81% of the patients within the first month.
Optimal time-hopping scheme for CDMA air interface in broad-band wireless systems

Time-hopping techniques have been applied in direct sequence code division multiple access (DS-CDMA) to reduce the harmful effects of a sudden power surge in the received signals. The conventional approaches may result in either nonuniform distribution of transmitting users among time slots or uneven interference from the dominant interferers. For both cases, the bit-error rate (BER) increases significantly for the users suffering the worst case condition. We propose an optimal time-hopping scheme based on the theory of finite projective planes for DS-CDMA to distribute interference evenly among participating users. The performance evaluation is divided into four parts. We demonstrate that both the average BER, probability of outage, and bandwidth efficiency can be improved by using the proposed time hopping scheme in comparison to other time-hopping schemes, such as the fixed allocation scheme and random selection scheme for various modulation methods including frequency shift keying-coherent demodulation (FSK-CD), differential phase shift keying (DPSK), binary phase shift keying (BPSK), and FSK with noncoherent demodulation (FSK-NCD). We compare the proposed time hopping scheme with nontime-hopping DS-CDMA with identical signal bandwidth. We then prove that the proposed scheme is optimal in minimizing interference.
GUS fusions: beta‐glucuronidase as a sensitive and versatile gene fusion marker in higher plants.

We have used the Escherichia coli beta‐glucuronidase gene (GUS) as a gene fusion marker for analysis of gene expression in transformed plants. Higher plants tested lack intrinsic beta‐glucuronidase activity, thus enhancing the sensitivity with which measurements can be made. We have constructed gene fusions using the cauliflower mosaic virus (CaMV) 35S promoter or the promoter from a gene encoding the small subunit of ribulose bisphosphate carboxylase (rbcS) to direct the expression of beta‐glucuronidase in transformed plants. Expression of GUS can be measured accurately using fluorometric assays of very small amounts of transformed plant tissue. Plants expressing GUS are normal, healthy and fertile. GUS is very stable, and tissue extracts continue to show high levels of GUS activity after prolonged storage. Histochemical analysis has been used to demonstrate the localization of gene activity in cells and tissues of transformed plants.

Continuous Delivery of D-Luciferin by Implanted Micro-osmotic Pumps Enables True Real-Time Bioluminescence Imaging of Luciferase Activity in Vivo

Bioluminescence imaging (BLI) of luciferase reporters in small animal models offers an attractive approach to monitor regulation of gene expression, signal transduction, and protein-protein interactions, as well as following tumor progression, cell engraftment, infectious pathogens, and target-specific drug action. Conventional BLI can be repeated within the same animal after bolus reinjections of a bioluminescent substrate. However, intervals between image acquisitions are governed by substrate pharmacokinetics and excretion, therefore restricting temporal resolution of reinjection protocols to the order of hours, limiting analyses of processes in vivo with short time constants. To eliminate these constraints, we examined use of implanted micro-osmotic pumps for continuous, long-term delivery of bioluminescent substrates. Pump-assisted d-luciferin delivery enabled BLI for ⩾ 7 days from a variety of luciferase reporters. Pumps allowed direct repetitive imaging at < 5-minute intervals of the pharmacodynamics of proteasome- and IKK-inhibiting drugs in mice bearing tumors stably expressing ubiquitin-firefly luciferase or IκBα-firefly luciferase fusion reporters. Circadian oscillations in the olfactory bulbs of transgenic rats expressing firefly luciferase under the control of the period1 promoter also were temporally resolved over the course of several days. We conclude that implanted pumps provide reliable, prolonged substrate delivery for high temporal resolution BLI, traversing complications of repetitive substrate injections.
Depth dose determinations. I. Tissue-equivalent liquids for standard man and muscle.

Requirements for tissue-equivalent mixtures are discussed, and methods are described for formulating mixtures exact in elemental composition and density. Methods are also given for estimating the densities and vapour pressures of mixtures of known compounds, as well as a list of the properties of compounds useful in tissue-equivalent formulations. A density value of 1.066+or-0.003g cm-3 at 37 degrees C is obtained for lean mammalian muscle, from the literature and from experiments. A density of 1.063 g cm-3 at 37 degrees C is obtained from the literature, for Standard Man exclusive of air voids. Tissue- equivalent liquids and their properties are presented for Standard Man and for lean muscle.
Stabilization of a class of underactuated mechanical systems via interconnection and damping assignment

We consider the application of a formulation of passivity-based control (PBC), known as interconnection and damping assignment (IDA) to the problem of stabilization of underactuated mechanical systems, which requires the modification of both the potential and the kinetic energies. Our main contribution is the characterization of a class of systems for which IDA-PBC yields a smooth asymptotically stabilizing controller with a guaranteed domain of attraction. The class is given in terms of solvability of certain partial differential equations. One important feature of IDA-PBC, stemming from its Hamiltonian formulation, is that it provides new degrees of freedom for the solution of these equations. Using this additional freedom, we are able to show that the method of "controlled Lagrangians"-in its original formulation-may be viewed as a special case of our approach. As illustrations we design asymptotically stabilizing IDA-PBCs for the classical ball and beam system and a novel inertia wheel pendulum.
Adrenocortical zonation factor 1 is a novel matricellular protein promoting integrin‐mediated adhesion of adrenocortical and vascular smooth muscle cells

Expression of a previously cloned secretory protein named adrenocortical zonation factor 1 (AZ‐1, also called Tin‐ag‐RP or lipocalin 7) is tightly linked with the zonal differentiation of adrenocortical cells. It is also present in vascular smooth muscle (VSM), although its function has remained unknown. In this study, the location of AZ‐1 was specified to the basal laminae along adrenocortical sinusoidal capillaries and surrounding VSM cells in the arterial system, consistent with the fact that AZ‐1 was extractable under denaturing conditions as a 52 kDa polypeptide. Purified recombinant AZ‐1 exhibited abilities to bind to fibronectins via the first type III repeat (anastellin) and to collagens with affinities in submicromolar ranges. AZ‐1 immobilized on substratum or bound to collagens or anastellin promoted adhesion and spreading of adrenocortical cells. Although VSM cells spread on AZ‐1 slowly, AZ‐1 bound to anastellin facilitated the spreading. The adhesion activity of AZ‐1 was mediated by a subset of integrins, including α1β1, α2β1, and α5β1, in a cell type‐specific manner. Collectively with the putative role of AZ‐1 in the adrenocortical zonation, we propose that AZ‐1 potentially regulates functions of adrenocortical and VSM cells by modulating cell–matrix interactions.
Similarity Search in Animal Sound Databases

In the past, similarity search for audio data has largely been focused on music. Recent digitization efforts in some of the larger animal sound archives bring other types of audio recordings into the focus of interest. Although recordings in animal sound archives are usually very well annotated by metadata, it is almost impossible to manually annotate all sounds made by animals in each recording. Complementary to classical text-based querying of databases that exploit available annotations, algorithms capable of automatically finding sections of recordings similar to a given query fragment provide a promising approach for content-based navigation. In our work, we present algorithms for feature extraction, as well as indexing and retrieval of animal sound recordings. Making use of a concept from image processing, the structure tensor, our feature extraction algorithm is adapted to the typical curve-like spectral features that are characteristic for many types of animal sounds. We propose a method for similarity search in animal sound databases which is obtained by adding a novel ranking scheme to an existing inverted file based approach for multimedia retrieval. Evaluation of our methods is based on recordings from the Animal Sound Archive, Berlin.
Visual servoing of patient robot's face and eye-looking direction to moving human

We have presented a system of patient robot developed with the aim at improving abilities of nursing student's medical treatment, such as injection to vein. To make patient robot human-like behavior, we have applied chaotic motion to the patient robot's behavior. In this paper, we propose visual servoing to follow a human face by 3-D pose recognition and eye-looking direction to moving human. Moreover, to evaluate the effectiveness of visual servoing, we execute an experiment that patient robot make behaves like a human by visual servoing with camera image.
General quantitative genetic methods for comparative biology: phylogenies, taxonomies and multi‐trait models for continuous and categorical characters

Although many of the statistical techniques used in comparative biology were originally developed in quantitative genetics, subsequent development of comparative techniques has progressed in relative isolation. Consequently, many of the new and planned developments in comparative analysis already have well‐tested solutions in quantitative genetics. In this paper, we take three recent publications that develop phylogenetic meta‐analysis, either implicitly or explicitly, and show how they can be considered as quantitative genetic models. We highlight some of the difficulties with the proposed solutions, and demonstrate that standard quantitative genetic theory and software offer solutions. We also show how results from Bayesian quantitative genetics can be used to create efficient Markov chain Monte Carlo algorithms for phylogenetic mixed models, thereby extending their generality to non‐Gaussian data. Of particular utility is the development of multinomial models for analysing the evolution of discrete traits, and the development of multi‐trait models in which traits can follow different distributions. Meta‐analyses often include a nonrandom collection of species for which the full phylogenetic tree has only been partly resolved. Using missing data theory, we show how the presented models can be used to correct for nonrandom sampling and show how taxonomies and phylogenies can be combined to give a flexible framework with which to model dependence.
Slow periodic motions in variable structure systems

Singularly perturbed relay control systems (SPRCS) which have stable periodic motion in reduced systems are studied. The slow motions integral manifold of such systems consists of parts which correspond to different values of control and the solutions of SPRCS contain the jumps from one part of the slow manifold to the other. The theorems about existence and stability of the slow periodic solutions are proved. An algorithm of asymptotic representation for this periodic solutions using a boundary layer method is suggested.
Practical Data-Dependent Metric Compression with Provable Guarantees

We introduce a new distance-preserving compact representation of multi-dimensional point-sets. Given $n$ points in a $d$-dimensional space where each coordinate is represented using $B$ bits (i.e., $dB$ bits per point), it produces a representation of size $O( d \log(d B/\epsilon) + \log n)$ bits per point from which one can approximate the distances up to a factor of $1 \pm \epsilon$. Our algorithm almost matches the recent bound of~\cite{indyk2017near} while being much simpler. We compare our algorithm to Product Quantization (PQ)~\cite{jegou2011product}, a state of the art heuristic metric compression method. We evaluate both algorithms on several data sets: SIFT (used in \cite{jegou2011product}), MNIST~\cite{lecun1998mnist}, New York City taxi time series~\cite{guha2016robust} and a synthetic one-dimensional data set embedded in a high-dimensional space. With appropriately tuned parameters, our algorithm produces representations that are comparable to or better than those produced by PQ, while having provable guarantees on its performance.
Robust repetitive control for time delay systems with application to nano manipulations

In this paper, a robust repetitive control for time delay systems is investigated supporting high precision tracking of nano-manipulating systems. To handle the time delay of such systems, the repetitive control structure is reformulated and the design of q filter is converted to the mixed sensitivity optimization of infinite dimensional systems, where Skew-Toeplitz based approach is used for controller synthesis. Real time experiments on a nano-manipulator are also deployed, where various periodic tracking results demonstrate the effectiveness of the proposed algorithm. The proposed algorithm has good potentials for high speed scanning applications such as AFM (Atomic Force Microscope) and STM (Scanning Tunneling Microscopy).
Scalable NUMA-aware Blocking Synchronization Primitives

Application scalability is a critical aspect to efficiently use NUMA machines with many cores. To achieve that, various techniques ranging from task placement to data sharding are used in practice. However, from the perspective of an operating system, these techniques often do not work as expected because various subsystems in the OS interact and share data structures among themselves, resulting in scalability bottlenecks. Although current OSes attempt to tackle this problem by introducing a wide range of synchronization primitives such as spinlock and mu-tex, the widely used synchronization mechanisms are not designed to handle both under-and over-subscribed scenarios in a scalable fashion. In particular, the current blocking synchronization primitives that are designed to address both scenarios are NUMA oblivious, meaning that they suffer from cache-line contention in an under-subscribed situation, and even worse, inherently spur long scheduler intervention, which leads to sub-optimal performance in an over-subscribed situation. In this work, we present several design choices to implement scalable blocking synchronization primitives that can address both under-and over-subscribed scenarios. Such design decisions include memory-efficient NUMA-aware locks (favorable for deployment) and scheduling-aware, scalable parking and wake-up strategies. To validate our design choices, we implement two new blocking synchronization primitives, which are variants of mutex and read-write semaphore in the Linux kernel. Our evaluation shows that these locks can scale real-world applications by 1.2–1.6 × and some of the file system operations up to 4.7 × in both under-and over-subscribed scenarios. Moreover, they use 1.5–10 × less memory than the state-of-the-art NUMA-aware locks on a 120-core machine.
A Miniaturized Wideband Wilkinson Power Divider

A miniaturized wideband Wilkinson Power Divider realized using OMMIC ED02AH Technology is presented. Simulation and optimization are accomplished by Advanced Design System (ADS). The final optimization results shows that it has a bandwidth of 76.5% (8.4 - 18.8 GHz), 1 dB insertion loss and good isolation (< -12 dB) between the output ports. The layout of the presented power divider is given, which shows that compacted size (0.75 × 0.45 mm2) is achieved successfully.

Byggeriets organisation har i stadig stigende grad vaeret til debat i det seneste 10 ar. Udgangspunktet for en raekke danske analyser og forsogsordninger har vaeret, at der grundlaeggende er noget galt med den made branchen, virksomhederne og byggeprojekterne er organiseret pa. Men byggeriets organisation har samtidig vist sig at vaere meget stabil over tid. Og hverken byggeriets nuvaerende organisering eller de dertil knyttede formodede problemer synes at vaere unikke for Danmark Byggeriets nuvaerende organisering ma alle darligdommene til trods have en eller anden fornuft i sig. Selv om det skaber nogle problemer, sa ma det lose andre. Men hvilke? Publikationen besvarer ud fra en fagokonomisk vinkel og ved hjaelp af omfattende empiriske studier dette sporgsmal. Dermed skabes en analytisk ramme til ikke bare at forsta byggebranchen, men ogsa til at forandre den. Med afsaet i en forstaelse af bade byggeriets svagheder og styrker diskuteres en raekke igangvaerende udviklingstiltag, bl.a. partnering, inden for byggeriet. Det pavises, at uagtet mange af tiltagene er sympatiske, vil de naeppe have den tilsigtede effekt. Publikationen slutter med at skitsere en radikal, men mulig vej til at sikre udviklingen af byggebranchen. ’Oer af stabilitet’ i eftersporgslen opnaet blandt andet gennem rammeaftaler og langvarige samarbejdsrelationer er en afgorende drivkraft i denne sammenhaeng.
