A method for personal query based on role preference ontology (2009)

To meet the needs of personal semantic query in information integrated systems, this paper applied role preference ontologies to express the preferences information belonged to different roles. Especially, we focused on self-maintenance of the role preference ontologies. It analyzed the query history of the registered user and calculated the preference weight value of the role preference ontology by using the formula of TF×IDF. The role preference ontology composed of a series of conceptions, sub-conceptions, attributions, instances and their preference weight values. Consequently, the system could return the personal semantic query results according to the preference information of the role preference ontologies.

Haploinsufficiency of Kruppel-Like Factor 4 Promotes Adenomatous Polyposis Coli–Dependent Intestinal Tumorigenesis (2007)

The zinc finger transcription factor Krüppel-like factor 4 (KLF4) is frequently down-regulated in colorectal cancer. Previous studies showed that the expression of KLF4 was activated by the colorectal cancer tumor suppressor adenomatous polyposis coli (APC) and that KLF4 repressed the Wnt/beta-catenin pathway. Here, we examined whether KLF4 plays a role in modulating intestinal tumorigenesis by comparing the tumor burdens in mice heterozygous for the Apc(Min) allele (Apc(Min/+)) and those heterozygous for both the Apc(Min) and Klf4 alleles (Klf4(+/-)/Apc(Min/+)). Between 10 and 20 weeks of age, Klf4(+/-)/Apc(Min/+) mice developed, on average, 59% more intestinal adenomas than Apc(Min/+) mice (P < 0.0001). Immunohistochemical staining showed that Klf4 protein levels were lower in the normal-appearing intestinal tissues of Klf4(+/-)/Apc(Min/+) mice compared with wild-type, Klf4(+/-), or Apc(Min/+) mice. In contrast, the levels of beta-catenin and cyclin D1 were higher in the normal-appearing intestinal tissues of Klf4(+/-)/Apc(Min/+) mice compared with the other three genotypes. Klf4 levels were further decreased in adenomas from both Apc(Min/+) and Klf4(+/-)/Apc(Min/+) mice compared with their corresponding normal-appearing tissues. Reverse transcription-PCR showed an inverse correlation between adenoma size and Klf4 mRNA levels in both Klf4(+/-)/Apc(Min/+) and Apc(Min/+) mice. There was also a progressive loss of heterozygosity of the wild-type Apc allele in adenomas with increasing size from Klf4(+/-)/Apc(Min/+) and Apc(Min/+) mice. Results from this study show that KLF4 plays an important role in promoting the development of intestinal adenomas in the presence of Apc(Min) mutation.
Fast implementations of LMS adaptive filters (1980)

A frequency domain implementation of the LMS adaptive transversal filter is proposed. This fast LMS (FLMS) adaptive filter requires less computation than the conventional LMS adaptive filter when the filter length equals or exceeds 64 sample points.
Melanotic odontogenic lesions (2012)

Melanin is rarely found in odontogenic tumors and cysts; but since the neural crest interacts in the development of teeth, it is not surprising that Melanocytes can occur in truly odontogenic tissue.
Social Networks (2017)

Many primates live in social groups because, on average, it pays to do so. While being in a group can increase competition for resources or the likelihood of contracting a disease, group living also provides more pairs of eyes for locating food sources and identifying potential threats. To evaluate the importance of social relationships requires an understanding of the different interactions that link all group members. Studying a variety of different social interactions that link all group members is hard because neither the interactions among individuals nor the different ways individuals interact are independent. Social network analysis is the study of social groups as networks of nodes connected by social ties. Using a social network approach provides a standardized and flexible framework to study social behavior, enabling primatologists to investigate the acquisition of information, novel behaviors, or even the transmission of pathogens and parasites both within and between social groups.
Survival and Causes of Mortality of Relocated and Resident Northern Bobwhites in East Texas (2017)

We estimated survival of 3 groups of northern bobwhites (Colinus virginianus) on a 563-ha intensively managed study area in eastern Texas. During the 3-year study, 155 bobwhites from South Texas and 136 bobwhites from East Texas were captured, radio-marked, and relocated to the study area; 139 bobwhites that were resident on the study area were also captured, radio-marked, and released at the point of capture. There were no differences (P > 0.05) in survival among the 3 groups of bobwhites. However, survival of bobwhites from South Texas were consistently lower than those of the other 2 groups during each year; both bobwhites from East Texas and resident bobwhites survived better than bobwhites relocated from South Texas. Avian predation claimed 57.6% of 243 known-fate birds, mammalian predation and apparent capture stress each caused 9.1 % mortality, while 1.2% of the birds died of snake predation and 14.0% were lost to unidentifiable causes.
Role of the Insulin-Like Growth Factor I Decline in the Induction of Atrogin-1/MAFbx during Fasting and Diabetes (2004)

In catabolic conditions, atrogin-1/MAFbx, a muscle-specific ubiquitin-ligase required for muscle atrophy, is increased, and concentrations of IGF-I, a growth factor known to have antiproteolytic action, are reduced. To define the relationship between the decline in IGF-I and the induction of atrogin-1/MAFbx, we studied the effect of IGF-I replacement on atrogin-1/MAFbx mRNA in rats fasted for 51 h and in rats made diabetic with streptozotocin (STZ). Fasting produced a 5.8-fold increase in atrogin-1/MAFbx (P < 0.001). This was attenuated to a 2.5-fold increase by injections of IGF-I (P < 0.05 vs. fasting). Animals with STZ-induced diabetes experienced a 15.1-fold increase in atrogin-1/MAFbx (P < 0.001). Normalization of their circulating IGF-I concentrations by IGF-I infusion blunted the induction of atrogin-1/MAFbx to 6.3-fold (P < 0.05 vs. STZ diabetes without IGF-I). To further delineate the regulation of atrogin-1/MAFbx by IGF-I, we studied a model of cultured muscle cells. We observed that IGF-I produced a time- and dose-dependent reduction of atrogin-1/MAFbx mRNA, with a 50% effective dose of 5 nm IGF-I, a physiological concentration. The degradation rate of atrogin-1/MAFbx mRNA was not affected by IGF-I, suggesting that the reduction of atrogin-1/MAFbx mRNA by IGF-I is a transcriptional effect. Exposure of muscle cells in culture to dexamethasone increased atrogin-1/MAFbx mRNA with a 50% effective dose of 10 nm, a pharmacological concentration. In the presence of dexamethasone, IGF-I at physiological concentrations retained its full inhibitory effect on atrogin-1/MAFbx mRNA. We conclude that IGF-I inhibits atrogin-1/MAFbx expression and speculate that this effect might contribute to the antiproteolytic action of IGF-I in muscle.
A new analysis of matched filter pseudo-noise code acquisition for direct sequence spread spectrum system (2002)

Rapid pseudo-noise (PN) code acquisition with matched filter correlators has been very popular in direct-sequence spread spectrum systems. Conventionally, the analysis of this acquisition method is based on the assumption that the detections between cells are independent. However, there may be strong correlations between cell detections for the case that the cell size is less than a chip duration. In this paper, the mean acquisition time performance of the acquisition method is analyzed with the cell correlations being taken into account. Numerical results show that depending on the threshold value and other system parameters the effect of cell correlations may be over 20% of the mean acquisition time for signal to noise ratios of practical interest. The analytical results are substantiated by using computer simulations.
Purification and Properties of Inosinic Acid Dehydrogenase from Escherichia coli (1969)

Abstract Inosinic acid dehydrogenase was prepared from a derepressed mutant of Escherichia coli. Although the reaction catalyzed formally resembles those catalyzed by chicken liver xanthine dehydrogenase and related enzymes, this enzyme is devoid of any flavin, iron complex, or molybdenum component, and the kinetics indicate necessity for concomitant binding of substrate and DPN. The enzyme is absolutely dependent on K+ or NH4+, which are competitive with the inhibitor Mg++. A series of purine nucleotides inhibits competitively with substrate with no evidence of cooperative interactions. The enzyme is quite unstable and can be separated into several distinct but enzymatically equivalent fractions by centrifugation or electrophoresis.
CO<sub>2</sub> partial pressure controls the calcification rate of a coral community (2000)

Summary Previous studies have demonstrated that coral and algal calcification is tightly regulated by the calcium carbonate saturation state of seawater. This parameter is likely to decrease in response to the increase of dissolved CO 2 resulting from the global increase of the partial pressure of atmospheric CO 2 . We have investigated the response of a coral reef community dominated by scleractinian corals, but also including other calcifying organisms such as calcareous algae, crustaceans, gastropods and echinoderms, and kept in an open‐top mesocosm. Seawater p CO 2 was modified by manipulating the p CO 2 of air used to bubble the mesocosm. The aragonite saturation state ( Ω arag ) of the seawater in the mesocosm varied between 1.3 and 5.4. Community calcification decreased as a function of increasing p CO 2 and decreasing Ω arag . This result is in agreement with previous data collected on scleractinian corals, coralline algae and in a reef mesocosm, even though some of these studies did not manipulate CO 2 directly. Our data suggest that the rate of calcification during the last glacial maximum might have been 114% of the preindustrial rate. Moreover, using the average emission scenario (IS92a) of the Intergovernmental Panel on Climate Change, we predict that the calcification rate of scleractinian‐dominated communities may decrease by 21% between the pre‐industrial period (year 1880) and the time at which p CO 2 will double (year 2065).
Building ontologies for different natural languages (2014)

Ontology construction of a certain domain is an important step in applying the Semantic web. A number of software tools adapted for building domain ontologies of most wide-spread natural languages are available, but accomplishing that for any given natural language presents a challenge. Here we propose a semi-automatic procedure to create ontologies for different natural languages. Our approach utilizes various software tools available on the Internet most notably DODDLE-OWL - a domain ontology development tool implemented for English and Japanese languages. By using this tool, WordNet, Prot?g? and XSLT transformations, we propose a general procedure to construct domain ontology for any natural language.
Optional and responsive fine-grain locking in Internet-based collaborative systems (2002)

Locking is a standard technique used in distributed computing and database systems to ensure data integrity by prohibiting concurrent conflicting updates on shared data objects. Internet-based collaborative systems are a special class of distributed applications which support human-to-human interaction and collaboration over the Internet. In this paper, a novel optional and responsive fine-grain locking scheme is proposed for consistency maintenance in Internet-based collaborative editors. In the proposed scheme, locking is made optional in the sense that a user may update any part of the document without necessarily requesting a lock. In the face of high communication latency in the Internet environment, responsive locking is achieved by granting the permit to the user for updating the data region immediately after issuing a locking request. Moreover, multiple fine-grain locks can be placed on different regions inside a document to allow concurrent and mutually exclusive editing on the same document. Protocols and algorithms for locking conflict resolution and consistency maintenance are devised to address special technical issues involved in optional and responsive fine-grain locking. The proposed locking scheme and supporting techniques were implemented in an Internet-based collaborative editor to demonstrate its feasibility and usability.
A new CMOS analog multiplier with improved input linearity (2002)

A new CMOS four-quadrant analog multiplier is presented. By means of an unique nonlinear compensation technique, the linear input range of the multiplier is extended significantly. The simulation results show that, when V/sub y/=/spl plusmn/3V, the nonlinear error is less than 0.94% over the /spl plusmn/3V input range of V/sub x/ and when V/sub x/=/spl plusmn/3V, the nonlinear error is less than 0.25% over the /spl plusmn/3V input range of V/sub y/, with a power supply of /spl plusmn/5V.
The deconvolution of phase-shifted wavelets (1982)

Abstract The assumption that a seismogram can be represented as a convolution of a source wavelet with a set of real impulses breaks down when the wavelet is phase shifted upon reflection from a boundary. For plane waves and plane layers, this effect occurs only for wide-angle supercritical reflections, but it may also occur in normal incidence seismograms when either the impinging wavefront or the reflective boundary is curved. We show that seismograms containing time-displaced, phase-shifted replications of the source wavelet can be deconvolved to recover both the amplitude and phase of the reflectivity coefficients. The method begins by writing the analytic seismogram as the convolution of a complex reflectivity function with an analytic source wavelet; linear inverse theory is then used to carry out the deconvolution.
Propranolol for the Control of Disruptive Behavior in Senile Dementia (1988)

Six patients with senile dementia, exhibiting severe, disruptive behavior were effectively treated with propranolol in doses ranging from 80 mg per day to 560 mg per day. All six patients were given a trial of propranolol after conventional therapy had failed, and in all patients, the agitated behavior significantly improved. There were no adverse side effects requiring the discontinuation of the propranolol, and in all cases, the agitated behavior was controlled without inducing general sedation. Both the nursing home staff and the families were pleased with the therapeutic effects. Propranolol represents a possible alternative way of addressing the severe problem of agitated behavior in senile dementia patients.
Two monoclonal antibodies specific for different epitopes within the amino-terminal region of F pilin (1986)

Two murine monoclonal antibodies (JEL 92 and 93) specific for adjacent epitopes on F pilin were purified and characterized. JEL 93 immunoglobulin G (IgG) and its Fab fragments were specific for the amino-terminal region and were completely reactive with a synthetic peptide representing the first eight amino acids of F pilin. The acetyl group was demonstrated to be an important part of the epitope, since an unacetylated version of the amino-terminal peptide was 100-fold less reactive with JEL 93 IgG. JEL 92 IgG reacted with the region of F pilin surrounding Met-9, represented by a tryptic peptide derived from the first 17 amino acids. This reactivity was completely abolished by cleavage of the peptide with cyanogen bromide. As shown by electron microscopy, both monoclonal antibodies bound to a vesiclelike structure at one end of purified free pili and did not bind to the sides of the pili, nor did they appear to bind to the tip. When sonication was used to break pili into shorter fragments, the number of binding sites for JEL 92 but not JEL 93 IgG increased as measured by a competitive enzyme-linked immunosorbent assay.

The <i>Saccharomyces cerevisiae LYS7</i> gene is involved in oxidative stress protection (1998)

Saccharomyces cerevisiae Lys7p was proposed to be the enzyme catalyzing the dehydratation of homocitrate to cis-homoaconitate, the second step of the lysine biosynthetic pathway. In this communication we provide evidence that Lys7p is involved in oxidative stress protection. Cells deleted for the LYS7 gene displayed, in addition to lysine auxotrophy, methionine auxotrophy, sensitivity to superoxide generating drugs and light irradiation, and diminution of calcineurin activity. The SOD1 gene encoding the Cu/Zn-superoxide dismutase was expressed in strains lacking Lys7p, and although Sodlp was produced in normal amounts no detectable enzyme activity was found. In contrast, the mitochondrial Mn-superoxide dismutase activity did not seem to be impaired. lys7 cells exhibited a normal uptake of Cu from growth medium. The Cu/Zn-superoxide dismutase activity was restored by addition of Cu (but not by addition of other metallic cations) to the growth medium or to cellular extracts, suggesting a lack of Cu2+ at the active site. These results render it necessary to reconsider the role of the Lys7p. Its involvement in Cu metabolism and oxidative-stress protection, and the possibility of a human equivalent in amyotrophic lateral sclerosis are discussed.
The Haemophilus somnus disease complex (Hemophilosis): A review. (1989)

Haemophilus somnus has long been associated with thrombotic meningoencephalomyelitis but has also been identified as the agent responsible for other clinical diseases including respiratory disease, reproductive problems, myocarditis, otitis, conjunctivitis, mastitis, and polyarthritis. Exposure to the bacteria is widespread and infection may occur via the respiratory tract from urogenital excretions and secretions.Diagnosis and treatment of hemophilosis may be easy or difficult depending on the manifestation presented, and special procedures must be taken to facilitate isolation of the organism. Satisfactory control measures are not available; vaccination is the only preventive measure demonstrating a beneficial effect.
Overlay Topology Based Inter-domain Qos Paths Building (2008)

The transport of multimedia flows over the internet needs to manage and control end to end quality of services (QoS) at transport level. Open issues still exist related to finding and maintaining QoS enabled paths through one or several independently administered domains. Among others, two tasks need to be solved: QoS routing or QoS enabled path finding and then maintaining these paths during data transfer. This paper deals with the problem of establishing QoS enabled aggregated multi-domain paths, to be later used for many individual streams. It is proposed a simple but extendable procedure, running at management overlay level, to find through communication between domain managers, several potential inter-domain end to end paths. Then, through resource negotiation process performed also in the management plane, QoS enabled aggregated pipes are established.
A Polynomial Time Algorithm That Learns Two Hidden Unit Nets (1990)

Let N be the class of functions realizable by feedforward linear threshold nets with n input units, two hidden units each of zero threshold, and an output unit. This class is also essentially equivalent to the class of intersections of two open half spaces that are bounded by planes through the origin. We give an algorithm that probably almost correctly (PAC) learns this class from examples and membership queries. The algorithm runs in time polynomial in n, ∊ (the accuracy parameter), and δ (the confidence parameter). If only examples are allowed, but not membership queries, we give an algorithm that learns N in polynomial time provided that the probability distribution D from which examples are chosen satisfies D(x) = D(−x) ∀x. The algorithm yields a hypothesis net with two hidden units, one linear threshold and the other quadratic threshold.
A Reliable Wireless Sensor System for Monitoring Mechanical Wear-Out of Parts (2014)

A ball screw is a typical mechanical part that experiences wear-out and is widely used in computer numerical control machine tools to control the movement of processing targets and spindles. These types of parts need frequent checks so that they are replaced before excessive wear occurs. Until now, there was no simple way to measure directly the state of wear quantitatively. An indirect approach is logging the signals (vibration, temperature, and preload change) during the operation of mechanical parts. This information can be used to construct a wear model for estimating its remaining lifetime. For embedding sensors into mechanical devices, wireless sensors bring advantages in that they may be installed freely without constraints from data or power cables. However, wireless transmission is subjected to interference. To make wireless sensors that can be used practically within an industrial environment, we propose a wireless sensor system that: 1) emphasizes low-power and low cost in hardware design; 2) logs the signals during the operation of a mechanical part that could experience wear; and 3) guarantees that all the logged data can be wirelessly delivered to the data server. To our knowledge, this is the first wireless sensor system for measurement of mechanical operation signals that guarantees complete data delivery and correctness. We designed, implemented, and evaluated this system in real environments. This ensures that the design is practical. We envision that a miniature version of our design could be embedded in the ball screw shaft and gearbox reducer for logging signals to enable the building of a wear model to estimate the part's lifetime.
