Pattern recognition based on multi-agent (2010)

Traditional method of pattern recognition confuse difference tow procession of pattern memory (microcosmic layer) and pattern classifying (macroscopic layer), it is main cause which the pattern methods are difficulty applied to solve really problem. A new frame of APRF (Agent-based Pattern Recognition Frame) is proposed based on Agent theory. The study goal of APRF are cognizing pattern from integral view, erecting the bridge between microcosmic layer and macroscopic layer and uncovering perplex of pattern emerge.
Level-set method for microscale flows (2016)

This chapter focuses on presenting a numerical method for two-phase ows in microscale systems using the level-set (LS) method of Osher and Sethian (1988). The interface is characterized using an LS function that is modeled as an additional scalar equation as part of the ˆnite-volume method (Patankar, 1980) used to model various transport phenomena. The main elements of the calculation procedure were presented by Yap et al. (2006). This chapter presents much of the same material in a condensed form. As a result, at times, readers are directed to the above-mentioned study for more details. Nevertheless, this chapter is more or less self-contained.
Delivering Nanoparticles and Molecules to the Same Spot with a Superhydrophobic Bulls-eye for Surface-enhanced Raman Scattering (2014)

We present a superhydrophobic silicon bulls-eye. Water droplets remain centered as they dry, enabling delivery of nanoparticles or molecules to the center. SERS spectra of molecules (R6G) at very low concentrations (10−15 M) are demonstrated.
A Cardiovascular Disease Risk Score Model Based on High Contribution Characteristics (2023)

Cardiovascular disease (CVD) risk prediction shows great significance for disease diagnosis and treatment, especially early intervention for CVD, which has a direct impact on preventing and reducing adverse outcomes. In this paper, we collected clinical indicators and outcomes of 14,832 patients with cardiovascular disease in Shanxi, China, and proposed a cardiovascular disease risk prediction model, XGBH, based on key contributing characteristics to perform risk scoring of patients’ clinical outcomes. The XGBH risk prediction model had high accuracy, with a significant improvement compared to the baseline risk score (AUC = 0.80 vs. AUC = 0.65). At the same time, we found that with the addition of conventional biometric variables, the accuracy of the model’s CVD risk prediction would also be improved. Finally, we designed a simpler model to quantify disease risk based on only three questions answered by the patient, with only a modest reduction in accuracy (AUC = 0.79), and providing a valid risk assessment for CVD. Overall, our models may allow early-stage intervention in high-risk patients, as well as a cost-effective screening approach. Further prospective studies and studies in other populations are needed to assess the actual clinical effect of XGBH risk prediction models.
Enhancement of Nucleate Boiling Heat Transfer With Nanofiber Mat (2012)

Nucleate pool boiling heat transfer has been experimentally studied at ambient temperature, on a surface with a novel nanofiber mat coating. The nano-textured surface was made of alumina ceramic substrate covered by an electrospun polymer nanofiber mat with a thickness of about 30 μm and immersed in saturated HCFC-123. The surfaces of the individual polymer nanofibers in the mat were copper-plated. Significant enhancements in nucleate boiling heat transfer as well as reduction of surface temperature have been achieved for the copper nanofiber-coated surface compared to a bare surface.
TiO 2 pigment structure and kinetics of PVC weathering (2000)

Abstract The influences of doping the core of TiO 2 pigments with Al 2 O 3 and of various inorganic surface modifications on the rate of poly(vinyl chloride) (PVC) weathering are investigated. The kinetics of loss of gloss are transformed into photooxidation rates by using Weibull statistics of failure, and a scheme of two consecutive reactions is fitted to the intermediate losses of brightness observed for the most photoactive pigments. When Ca/Zn stabilizers in PVC are exchanged for Pb stabilizers, gloss degradation rate doubles, and the energetic spread of irradiation defects broadens. No indications for specific interactions between pigment and stabilizer are found.
Use of frequency domain analysis for signal-to-noise ratio enhancement in stacking (2003)

An algorithm is presented for the stacking of seismic CMP (common midpoint) gathers. It is characterized by improved signal-to-noise ratio over the conventional method. The procedure is based on the principle that Fourier coefficients that contain more noise than signal should be excluded from the stacked trace. This selective process is accomplished by means of coherency coefficients aimed at estimating the phase agreement among Fourier coefficients of traces in the gather. It is concluded that while this selective stacking procedure requires an excessive amount of computation in comparison with conventional stacking, in some situations it may be the only viable alternative to improving the signal-to-noise ratio. Synthetic seismic data are used to demonstrate the stacking scheme and its improved noise-reduction capability.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Studies of Aphthovirus Subunits and Synthetic Peptides Relevant to Their Use as Vaccines Against Foot and Mouth Disease. (1986)

Laboratory animals and cattle were vaccinated with the aphthovirus capsid protein VPl or with aphthovirus-specific synthetic peptides. The peptides used copied either the sequence of amino-acids 141-160 from the VPl of aphthovirus strains OlBFS 1860 and 01 Kaufbeuren (the 0 peptide) or the equivalent sequence from aphthovirus strain A24 Cruzeiro (the A peptide). VPl was isolated by chromatofocusing from aphthovirus strains OlBFS 1860, A24 Cruzeiro and Asia 1 Iran 1/73. The 0 peptide and the VPls were poorly immunogenic, even when coupled to keyhole limpet haemocyanin (KLH), and conferred little or no protection against challenge with infectious virus. In contrast KLH-A peptide had good immunogenicity and vaccinated guinea-pigs were protected from challenge. All animals vaccinated with KLH-peptide demonstrated considerable diversity in their responses, both between strains and between individuals of the same strain. These results may reflect differences between 0 and A serotype viruses and variations in the immune response genes of the animals studied. The immune responses were long-lasting. Guinea-pigs and rabbits possessed significant levels of antibody a year after vaccination, though the specificity of the antibody varied with species and peptide. In some species KLH-peptide stimulated an anamnestic immune response. However, in vitro experiments with mouse splenocytes showed that peptides were less effective than virus in this respect. KLH-peptide was less immunogenic, in terms of conferring protection and generating neutralizing antibodies, than virus. Sera from KLH-peptide-vaccinated guinea-pigs were relatively inefficient at forming immune complexes with virus and at neutralizing virus. Peptide-induced neutralizing antibodies appeared to correspond to a weakly-neutralizing sub-population of virus-induced neutralizing antibodies.

Radar target identification with relative amplitudes and unknown target aspect angles (2002)

An approach to radar target identification that uses a modified nearest neighbor algorithm and relative amplitude target features is proposed. It assumes that the aspect angles (elevation and azimuth) of the target to be identified are unknown. The relative amplitude features are the ratios of the target amplitude returns of two different frequencies, and they are two-dimensional functions of the target aspect angles. The features are also related to target geometry, wave polarization, and frequency, but are independent of target range and other radar system parameters. The database contains a finite number of samples of reference target features taken at certain target aspect angles. The differences between the aspect angles of the unknown target and those of the samples, called the aspect offsets, cause identification error. An unknown target is considered identified if its nearest neighbor in the feature space is in the set of feature samples from the same reference target in the database. A computer simulation was conducted to determine the misidentification percentage, due to the aspect offsets, as a function of the aspect angle sampling intervals and the number of frequencies, based on amplitude returns from multiple point scatters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
[Pediatric suspensions of amoxicillin and clavulanic acid in the treatment of bacterial infections of otorhinolaryngologic importance and the upper respiratory tract]. (1989)

Thirty children, 20 males and 10 females, aged 6.57 +/- 0.78 on the average (range: from 13 to 6 months), weighing 21.60 +/- 2.25 kg with bacterial infections of the upper respiratory tract and ear were admitted to the present trial. A chemotherapeutic agent based on amoxycillin and clavulanic acid in the suspension for children of 312.5 mg/5 ml (4:1 ratio) at the dosage of about 17 mg/kg in two daily administrations according to the weight of the patients was used. The therapy was prolonged for 8.87 +/- 0.30 days on the average, from a minimum of 3 to a maximum of 11 days. In the course of the treatment the symptom parameters and the objective signs progressively reduced until disappearance; the body temperature came promptly back to normal values, confirming the definite improvement and the regression of the infectious pictures. The microbiological data also fully confirmed the successful activity of the chemoantibiotic drug used. No side effects were found and, as regards local and general tolerance, no signs of an even slight impairment related to the administration of the drug were found. The final judgement expressed on the efficacy, on the basis of the more or less quick and complete symptom regression, evolution of the infectious picture and good tolerance were the following: excellent in 22 cases, good in 6, fair in 1 and not able to be evaluated in 1 case (a female patient who left off the trial).
The In Vitro and In Vivo Ocular Pharmacology of Olopatadine (AL-4943A), an Effective Anti-Allergic/Antihistaminic Agent (1996)

Olopatadine (AL-4943A; KW-4679) [(z)-11-[3-(dimethylamino)propylidene]-6, 11-dihydrodibenz[b,e]oxepine-2 acetic acid hydrochloride] is an anti-allergic agent which inhibits mast cell mediator release and possesses histamine H1 receptor antagonist activity. Studies were conducted to characterize the in vitro and in vivo pharmacological profile of this drug relevant to its topical ocular use. AL-4943A inhibits histamine release in a concentration-dependent fashion (IC50 = 559 microM) from human conjunctival mast cell preparations in vitro. Histamine release was not stimulated by AL-4943A at concentrations as high as 10 mM. In contrast, ketotifen stimulated histamine release at concentrations slightly higher than effective inhibitory concentrations. AL-4943A did not display any in vitro cyclooxygenase or 5-lipoxygenase inhibition. Topical ocular application of AL-4943A effectively inhibits antigen- and histamine-stimulated conjunctivitis in guinea pigs. Passive anaphylaxis in guinea pig conjunctiva was attenuated by AL-4943A applied 30 min prior to intravenous or topical ocular antigen challenge (ED50 values 0.0067% and 0.0170%, w/v, respectively). Antihistaminic activity in vivo was demonstrated using a model of histamine-induced vascular permeability in guinea pig conjunctiva. AL-4943A applied topically from 5 min to 24 hrs prior to histamine challenge effectively and concentration-dependently inhibited the vascular permeability response, indicating the compound has an acceptable onset and a long duration of action. Drug concentrations 5-fold greater than those effective against histamine-stimulated conjunctival responses failed to inhibit vascular permeability responses induced with either serotonin or Platelet-Activating-Factor. These data indicate that the anti-histaminic effect observed with AL-4943A is specific. These anti-allergic/antihistaminic activities of AL-4943A observed in preclinical model systems have been confirmed in clinical trials in allergic patients.
Development of Single Sign-On System with Hardware Token and Key Management Server (2007)

With the growth of the Internet, various types of services, such as World Wide Web (WWW), file transfer protocol (FTP), remote login, etc., are widely expanded. Consequently, it is difficult for users to manage all the authentication information, e.g., user ID/Password pairs, keys, and certificates, since the authentication information has been increased to use those services. Therefore, single sign-on (SSO) system, which makes all the services available for a user by only one-time authentication, has been developed. However, existing systems cannot provide all the SSO services for any kinds of services on the Internet even if the service provider deploys the SSO server. Therefore, in this paper, we propose a new SSO system with hardware token and key management server to improve the safety and the convenience. Furthermore, we implement the proposed system, and show its effectiveness through evaluation. In addition, adding any functions for this system provide various conveniences to us. As one example, we add high trust connection function for a Web server, and show its the effectiveness through evaluation by implementing it.
Play fuckin' loud: Zizek versus the left (2006)

Although adult ascidians have remarkable regenerative potency, the ascidian egg is considered a typical "mosaic" egg. A single blastomere isolated at the two-cell stage develops into a half tadpole with minor or major defects, and this rigidity of ascidian development is known to depend on the localization of cytoplasmic determinants. Between the egg and adult, the ascidian larva has a dual nature consisting of differentiated cells for larval activities and undifferentiated cells that later become differentiated and function in the adult. Although ascidian larvae derived from a hemiembryo are deficient, no one has yet investigated the possibility that the adult might have regulative powers not present in the embryo and might be able to form an entire adult ascidian. Using Styela plicata, we have approached this problem. We report here for the first time that ascidian half embryos can form tadpoles that have the potency to hatch, metamorphose, and develop into functional ascidians.
Quantitative analysis of γ–oryzanol content in cold pressed rice bran oil by TLC–image analysis method (2014)

The TLC-densitometric and TLC-image analysis methods provided a similar reproducibility, accuracy and selectivity for the quantitative determination of γ-oryzanol in cold pressed rice bran oil. A statistical comparison of the quantitative determinations of γ-oryzanol in samples did not show any statistically significant difference between TLC-densitometric and TLC-image analysis methods. As both methods were found to be equal, they therefore can be used for the determination of γ-oryzanol in cold pressed rice bran oil.
Cell responses in dorsal layers of macaque lateral geniculate nucleus as a function of intensity and wavelength (1983)

We studied the relationship between light intensity and cell response to various wavelengths and wavelength combinations in the dorsal, parvocellular layers of the macaque lateral geniculate nucleus. When response is plotted as a function of the logarithm of stimulus intensity, the slope and shape of curves depends on wavelength. For wavelengths near the crossover point between excitatory and suppressive responses, nonmonotonic curves are common. Consequently, the form of spectral-response functions depends on stimulus intensity. Responses to combined stimuli made up of wavelengths close together near one spectral extreme are approximately additive. If one wavelength is near the crossover point, responses are nonadditive so that a midspectral wavelength, only producing a weak excitatory response, is able to occlude more vigorous responses to wavelengths near the spectral ends. Responses of parvocellular layer cells are consistent with their being a result of linear interaction of opponent cone mechanisms, the response of each of which follows a modified hyperbolic tangent function (22). Responses to all wavelength combinations, even those showing strikingly nonadditive effects, could be predicted from the additive opponent model described above.
The Value of Urethral Sphincter Electromyography in the Differential Diagnosis of Parkinsonism (1989)

A series of 54 patients presenting with parkinsonism underwent clinical assessment and urethral sphincter electromyography (EMG). After clinical assessment, 26 were thought to be suffering from probable multiple system atrophy (MSA), 15 were thought to have possible MSA and 13 were diagnosed as having probable idiopathic Parkinson's disease (IPD). Of those with probable MSA, 16 were found to have an abnormal urethral sphincter EMG. In the group with possible MSA, only 5 patients had an abnormal EMG while in the group with probable IPD, only 1 patient had an abnormal EMG. It was concluded that urethral sphincter electromyography provides a useful method of distinguishing between idiopathic Parkinson's disease and multiple system atrophy. It also provides a means of identifying those patients with parkinsonism whose incontinence may well be worsened, or in whom incontinence may develop following lower urinary tract surgery.
Novel Alleles for Combined Drought and Heat Stress Tolerance in Wheat (2020)

Drought and heat waves commonly co-occur in many wheat-growing regions causing significant crop losses. The identification of stress associated quantitative trait loci, particularly those for yield, is problematic due to their association with plant phenology and the high genetic × environment interaction. Here we studied a panel of 315 diverse, spring type accessions of bread wheat (<i>Triticum aestivum</i>) in pots in a semi-controlled environment under combined drought and heat stress over 2 years. Importantly, we treated individual plants according to their flowering time. We found 134 out of the 145 identified loci for grain weight that were not associated with either plant phenology or plant height. The majority of loci uncovered here were novel, with favorable alleles widespread in Asian and African landraces providing opportunities for their incorporation into modern varieties through breeding. Using residual heterozygosity in lines from a nested association mapping population, we were able to rapidly develop near-isogenic lines for important target loci. One target locus on chromosome 6A contributed to higher grain weight, harvest index, thousand kernel weight, and grain number under drought and heat stress in field conditions consistent with allelic effects demonstrated in the genome-wide association study.
Mycoviromic Analysis Unveils Complex Virus Composition in a Hypovirulent Strain of Sclerotinia sclerotiorum (2022)

Mycoviruses are ubiquitous in pathogenic fungi including <i>Sclerotinia sclerotiorum</i>. Using RNA sequencing, more mycoviruses have been identified in individual strains, which were previously reported to be infected by a single mycovirus. A hypovirulent strain of <i>S. sclerotiorum</i>, HC025, was previously thought to harbor a single mitovirus, Sclerotinia sclerotiorum mitovirus 1 (SsMV1), based on the analysis of the conventional dsRNA extraction method. We found HC025 to be co-infected by five mycoviruses. In addition to SsMV1, four mycoviruses were identified: Sclerotinia sclerotiorum narnavirus 4 (SsNV4), Sclerotinia sclerotiorum negative-stranded RNA virus 1 (SsNSRV1), Sclerotinia sclerotiorum ourmia-like virus 14 (SsOLV14), and SsOLV22. Three mycoviruses including SsNV4, SsNSRV1, and SsOLV14 share high replicase identities (more than 95%) with the previously reported corresponding mycoviruses, and SsOLV22 shows lower identity to the known viruses. The complete genome of SsOLV22 is 3987 nt long and contains a single ORF-encoded RdRp, which shares 24.84% identity with the RNA-dependent RNA polymerase (RdRp) of Hubei narna-like virus 10 (query coverage: 26%; e-value: 8 × 10<sup>-19</sup>). The phylogenetic tree of RdRp suggests that SsOLV22 is a new member within the family <i>Botourmiaviridae</i>. All of the mycoviruses except for SsNSRV1 could horizontally co-transfer from HC025 to the virulent strain Ep-1PNA367 with hypovirulent phenotypes, and converted a later strain into a hypovirulent strain. In summary, we molecularly characterized the hypovirulent strain HC025 and identified five RNA mycoviruses including a new member within <i>Botourmiaviridae</i>.
