FastRAQ: A Fast Approach to Range-Aggregate Queries in Big Data Environments (2014)

Range-aggregate queries are to apply a certain aggregate function on all tuples within given query ranges. Existing approaches to range-aggregate queries are insufficient to quickly provide accurate results in big data environments. In this paper, we propose FastRAQ-a fast approach to range-aggregate queries in big data environments. FastRAQ first divides big data into independent partitions with a balanced partitioning algorithm, and then generates a local estimation sketch for each partition. When a range-aggregate query request arrives, FastRAQ obtains the result directly by summarizing local estimates from all partitions. FastRAQ has O(1) time complexity for data updates and O(N/P×B) time complexity for range-aggregate queries, where N is the number of distinct tuples for all dimensions, P is the partition number, and B is the bucket number in the histogram. We implement the FastRAQ approach on the Linux platform, and evaluate its performance with about 10 billions data records. Experimental results demonstrate that FastRAQ provides range-aggregate query results within a time period two orders of magnitude lower than that of Hive, while the relative error is less than 3 percent within the given confidence interval.
Dolichol phosphate mannose synthase from the filamentous fungus Trichoderma reesei belongs to the human and Schizosaccharomyces pombe class of the enzyme (2000)

Dolichol phosphate mannose (DPM) synthase activity, which is required in N:-glycosylation, O-mannosylation, and glycosylphosphatidylinositol membrane anchoring of protein, has been postulated to regulate the Trichoderma reesei secretory pathway. We have cloned a T.reesei cDNA that encodes a 243 amino acid protein whose amino acid sequence shows 67% and 65% identity, respectively, to the Schizosaccharomyces pombe and human DPM synthases, and which lacks the COOH-terminal hydrophobic domain characteristic of the Saccharomyces cerevisiae class of synthase. The Trichoderma dpm1 (Trdpm1) gene complements a lethal null mutation in the S.pombe dpm1(+) gene, but neither restores viability of a S.cerevisiae dpm1-disruptant nor complements the temperature-sensitivity of the S. cerevisiae dpm1-6 mutant. The T.reesei DPM synthase is therefore a member of the "human" class of enzyme. Overexpression of Trdpm1 in a dpm1(+)::his7/dpm1(+) S.pombe diploid resulted in a 4-fold increase in specific DPM synthase activity. However, neither the wild type T. reesei DPM synthase, nor a chimera consisting of this protein and the hydrophobic COOH terminus of the S.cerevisiae DPM synthase, complemented an S.cerevisiae dpm1 null mutant or gave active enzyme when expressed in E.coli. The level of the Trdpm1 mRNA in T.reesei QM9414 strain was dependent on the composition of the culture medium. Expression levels of Trdpm1 were directly correlated with the protein secretory capacity of the fungus.
An Analysis of W-fibers and W-type Fiber Polarizers (2001)

Optical fibers provide the means for transmitting large amounts of data from one place to another and are used in high precision sensors. It is important to have a good understanding of the fundamental properties of these devices to continue to improve their applications. A specially type of optical fiber known as a W-fiber has some desirable properties and unique characteristics not found in matched-cladding fibers. A properly designed W- fiber supports a fundamental mode with a finite cutoff wavelength. At discrete wavelengths longer than cutoff, the fundamental mode experiences large amounts of loss. The mechanism for loss can be described in terms of interaction between the fiber's supermodes and the lossy interface at the fiber's surface. Experiments and computer simulations support this model of W-fibers. The property of a finite cutoff wavelength can be used to develop various fiber devices. Under consideration here is the fiber polarizer. The fiber polarizer produces an output that is linearly polarized along one of the fiber's principal axes. Some of the polarizer properties can be understood from the study of W-fibers.

A fully provisioned 238/spl times/238 beam-steering optical crossconnect constructed using surface micromachined mirrors is described. The mean fiber-to-fiber insertion loss of the fabric is 1.33dB and the maximum insertion loss is 2dB.
Metacarpophalangeal Joint Prostheses: A Review of past and Current Designs (1993)

The anatomy and biomechanics of the metacarpophalangeal (MCP) joint are briefly described. Hinge, flexible and surface designs of past and current MCP prosthetic joints are reviewed, outlining their respective advantages and disadvantages. Although existing prostheses can restore cosmetic appearance and relieve pain, none can equal the stability and versatility of the natural joint. Delayed reconstructive surgery may be partly responsible for the mediocre results experienced, since the later the surgery the worse will be the condition of the muscles and ligaments surrounding the joint. These are the structures responsible for strength, movement and stability of the joint. From a mechanical viewpoint it may be desirable to operate at an earlier stage of the disease than is currently indicated, but this is a clinical decision. Some design aspects, namely fixation and wear, require a different approach when designing an MCP prosthesis from that adopted in the case of prosthetic hips and knees.
Speaker-independent auditory attention decoding without access to clean speech sources (2019)

Speech perception in crowded environments is challenging for hearing-impaired listeners. Assistive hearing devices cannot lower interfering speakers without knowing which speaker the listener is focusing on. One possible solution is auditory attention decoding in which the brainwaves of listeners are compared with sound sources to determine the attended source, which can then be amplified to facilitate hearing. In realistic situations, however, only mixed audio is available. We utilize a novel speech separation algorithm to automatically separate speakers in mixed audio, with no need for the speakers to have prior training. Our results show that auditory attention decoding with automatically separated speakers is as accurate and fast as using clean speech sounds. The proposed method significantly improves the subjective and objective quality of the attended speaker. Our study addresses a major obstacle in actualization of auditory attention decoding that can assist hearing-impaired listeners and reduce listening effort for normal-hearing subjects.
Robust line tracking using a particle filter for camera pose estimation (2006)

This paper presents a robust line tracking approach for camera pose estimation which is based on particle filtering framework. Particle filters are sequential Monte Carlo methods based on point mass (or "particle") representations of probability densities, which can be applied to any state-space model. Their ability to deal with non-linearities and non-Gaussian statistics allows to improve robustness comparing to existing approaches, such as those based on the Kalman filter. We propose to use the particle filter to compute the posterior density for the camera 3D motion parameters. The experimental results indicate the effectiveness of our approach and demonstrate its robustness even when dealing with severe occlusion.

Calculation of photon dose distributions in an inhomogeneous medium using convolutions (1986)

A formulation of the single energy photon transport problem is cast in the form of a series of convolutions over the primary fluence distribution with invariant kernels. A method is developed for compensating for the variant intervoxel attenuation in the scattered dose distribution by means of an invariant correction kernel. Results of applying the formulation to 60Co distributions in the presence of slab and block inhomogeneities are presented.
Towards Achieving Personalized Privacy for Location-Based Services (2009)

With the growth of wireless and mobile technologies, we are witnessing an increase in location-based services (LBSs). Although LBSs provide enhanced functionalities, they open up new vulnerabilities that can be exploited to cause security and privacy breaches. Consequently, location data of individuals used by such services must be adequately protected. Such services will require new models for expressing privacy preferences for location data and mechanisms for enforcing them. We identify the factors on which location privacy depends and propose models for expressing privacy that can be used by LBSs. We discuss the architecture of a system that allows one to specify and enforce location privacy and that can be easily integrated with existing systems providing LBSs. We demonstrate the feasibility of our approach by developing a prototype.

AN ATTEMPT TO EVALUATE THE STEROIDOGENIC ACTIVITY OF SYNTHETIC ADRENOCORTICOTROPIC PEPTIDES: THE CIRCULATION METHOD (1966)

Apparent differences between the time curves (as determined by a method designated as the circulation method) of corticosterone concentration in the adrenal venous blood in hypophysectomized rats followed by the administration of natural ACTH and synthetic adrenocorticotropic peptides were demonstrated. When the areas under the curves obtained for 2 or 3 different doses of various adrenocorticotropic preparations were assumed as the responses, parallel dose-response regression lines were obtained for all the peptides tested. The relative potencies computed form this dose-response relationship somewhat differed from those by the established methods. It is suggested that the circulation method may be useful in evaluating the adrenal-stimulating potency of various preparations for therapeutic purposes.
[Effects of long-term preoperative administration of low-dose erythromycin on warm ischemia-reperfusion pulmonary injury]. (1998)

The effects of long-term preoperative administration of low-dose erythromycin (EM) were experimentally examined in relation to the treatment of reperfusion disorders following pulmonary thermal ischemia. EM was administered at a dose of 100 mg/day for 1 month to adult mongrel dogs with an average weight of about 12 kg (EM group). A control group that did not receive EM was also enrolled. Using a pulmonary autograft model, collapse-thermal ischemia of the lungs was performed on each animal for 60 minutes. In the early stage of reperfusion, the following measurements were assessed: gas-exchange potency in the left lung, hemodynamics, water content, adhesion of neutrophils to vascular endothelium, and concentration of blood eicosanoids. The results for the 2 groups were then compared. In the control group, the blood level of leukotriene B4 (LTB4) increased shortly after reperfusion, neutrophils migrated toward the vascular endothelium and adhered to it, and pulmonary edema developed after 1 hour. However in the EM group, the blood level of thromboxane B2 was significantly suppressed before and after hilar stripping, and the increase in the blood LTB4 level and the migration of neutrophils shortly after reperfusion in thermal ischemia were suppressed. Eventually alleviation of pulmonary edema was indicated and significantly improved gas exchange was maintained. In conclusion, pulmonary injury during detachment of the hilum of the lung, as well as warm ischemia-reperfusion pulmonary injury, may be alleviated by preoperative administration of low-dose EM on a long-term basis.
On the use of splitting vectors with zero components for constrained encoder design (2002)

The state-splitting algorithm is a method for designing an encoder for a constrained system of the type prevalent in digital recording system technology. Traditionally, the starting point of the state-splitting algorithm involves finding a "splitting vector", a vector with positive integer components whose component sum is an upper bound on the number of states of the encoder to be designed. We give a tutorial on the use of splitting vectors in which some of the components are allowed to be zero. This leads to an encoder with fewer states in some cases. The MATLAB code is given for generating such splitting vectors.
The cw electro-optical properties of (Al,Ga)As modified-strip buried-heterostructure lasers (1980)

This paper presents a detailed study of the cw propeties of a modified-strip buried-heterostructure (MSBH) laser. Included are studies of the electrical, electro-optical, and optical beam properties, together with spectral characteristics, and temperature dependence of thresholds. A variation of this type of laser, a passive-mirror modified-strip buried heterostructure is also described. The MSBH laser possesses many desirable properties including excellent linearity of the lasing emission consistent with a second-harmonic content more than 40 dB below the fundamental, constant proportionality between the light emitted from the two mirror facets, ’’kink-free’’ emission to the maximum cw power levels measured (35 mW/mirror facet), nearly round near-field intensity distribution with an ellipicity of 1.3 : 1, lasing emission in the lowest-order transverse mode, full angle half-power perpendicular to the junction plane of 27.3° (significantly smaller than any other practical cw DH laser structure), and narrow cw spectra (emission is typically in only a few longitudinal modes). MSBH lasers are nonastigmatic signal sources so that diffraction-limited spherical optics can be used. Pulsations are not observed if the active stripe is free of absorbing defects. cw operation of 10 mW/mirror facet was obtained at ambient temperatures to 90 °C with a T0 of 126 °K. For 380-μm-long lasers pulsed threshold currents of 78 mA dc, slope efficiencies of 63%, forward resistances of 2 Ω, and zero-biased capacitances of 15 pF have been measured. At the operating power of 3 mW/mirror facet, the optical power density at the mirror facet is low (?104 W/cm2) which may have positive reliability implications. The passive-mirror form of the MSBH laser (PM-MSBH laser), with the potential for avoiding surface effects which have been implicated as a cause of pulsations and laser degradation, have been measured with thresholds of 104 mA dc and slope efficiencies of 31%.
Design and implementation of a relational query language with teams (2002)

We introduce the concept "team" and incorporate the team query into the data language SQL. Existing relational query languages use tuple variables of tables to specify required data. Queries that are expressed by these languages are used to get all the data which satisfy the specified conditions. While a team variable represents a subset of a table, a team query is used to retrieve all the teams that meet certain constraints. We introduce team qualifications and briefly describe team query processing. The search space of a team query may be very large. Therefore, instead of using conventional breadth-first search method, we adopt a depth-first search method for query processing. Thus, users can always get a result if one exists.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Neural Network System for the Identification of Infrared Spectra (1992)

A neural network system has been developed on a personal computer to identify 1129 infrared spectra. The system is composed of two steps of networks. The first step classifies 1129 spectra into 40 categories, and each unit of the output layer is connected to one of the 40 networks in the second step, which identify each spectrum. Each network is composed of three layers. The input, intermediate, and output layers are composed of 250, 40, and 40 units, respectively. Intensity data at 250 wavenumber points between 1800 and 550 cm −1 of the infrared spectra are entered into the input layer of each network. The training of the networks was carried out with the spectral data of 1129 compounds stored in the SDBS system, and thus the networks were successfully constructed. On the basis of the results, the system has been developed by preparing pre- and post-processing programs. The system can identify each unknown spectrum within 0.1 s, and is quite efficient for identifying infrared spectra on a personal computer.
Optical residue arithmetic computer with programmable computation modules (1979)

The concept of a programmable multipurpose computation module for residue arithmetic is introduced. A possible design for the module is also presented. The application of the computation module in mathematical computation, coding, decoding, and scaling is demonstrated. Very high throughput rate is achieved by the use of parallel computation structures and pipelining of sequential operations.
Infections Caused by Propionibacterium Species (1991)

Eight hundred and sixteen isolates of Propionibacterium species (725 of which were Propionibacterium acnes) were isolated from 3,971 specimens submitted for the identification of anaerobic bacteria over the course of 10 years. A total of 94 Propionibacterium isolates (12%) identified in 92 patients were considered to cause infection. The rest of the isolates were determined to be contaminants or of uncertain pathogenic significance. Significant infections caused by Propionibacterium species were associated with the blood in 15 patients, central nervous system in 11, lymph glands in 10, abscesses in eight, joints in seven, wounds in seven, cysts in six, and sinuses in five. Predisposing or underlying conditions were noted in 66 patients (70%). The most common conditions were the presence of foreign bodies (29 patients), diabetes (12), previous surgery (10), trauma (seven), malignancy (seven), immunodeficiency (seven), and steroid therapy (four). Antimicrobial therapy was administered to 83 patients; for 47 patients this therapy was given in conjunction with surgical drainage or correction. Surgical drainage alone was performed in nine patients. Five patients (5%) died. These data illustrate that although Propionibacterium species are rarely associated with infections, these organisms can occasionally cause serious infections.

Nutritional and botanical interventions to assist with the adaptation to stress. (1999)

Prolonged stress, whether a result of mental/emotional upset or due to physical factors such as malnutrition, surgery, chemical exposure, excessive exercise, sleep deprivation, or a host of other environmental causes, results in predictable systemic effects. The systemic effects of stress include increased levels of stress hormones such as cortisol, a decline in certain aspects of immune system function such as natural killer cell cytotoxicity or secretory-IgA levels, and a disruption of gastrointestinal microflora balance. These systemic changes might be a substantial contributor to many of the stress-associated declines in health. Based on human and animal research, it appears a variety of nutritional and botanical substances - such as adaptogenic herbs, specific vitamins including ascorbic acid, vitamins B1 and B6, the coenzyme forms of vitamin B5 (pantethine) and B12 (methylcobalamin), the amino acid tyrosine, and other nutrients such as lipoic acid, phosphatidylserine, and plant sterol/sterolin combinations - may allow individuals to sustain an adaptive response and minimize some of the systemic effects of stress.
