This study explored the usefulness of genomic copy number variation sequencing (CNV-Seq) in the prenatal diagnosis of pregnant women.Based on prenatal diagnostic indications, CNV-Seq analysis was done in the samples from the 579 pregnant women of the 7 subgroups that included advanced maternal age (group A), high risk noninvasive prenatal test (NIPT) (group B), high risk Down's (Group C), abnormal ultrasound findings (Group D), adverse pregnancy history (Group E), chromosome abnormalities in couples (Group F), and the mixed group (Group G).A total of 57 (9.84%) cases have abnormal CNV-Seq results. Among them, 21 cases were aneuploid chromosomal number abnormalities (3.63%, 21/579), and 36 cases were CNV abnormalities (6.22%, 36/579), including 7 cases of pathogenic copy number alteration (pCNA) (1.21%, 7/579) and 29 cases variants of uncertain significance (VUS) (5.01%, 29/579). The total detection rates of abnormal CNV-Seq in Group G and Group B were 20.27% (15/74) and 15.91% (14/88), which were significantly higher than those in other groups (p0.05). Among 36 cases of abnormal CNV-Seq, 7 cases were chromosome fragment deletion or duplication, which were pathogenic CNV, and some rare chromosomal diseases were detected.Patients with a high risk of NIPT or multiple indications of prenatal diagnosis are highly suspected of chromosomal diseases. CNV-Seq is a useful tool for detecting chromosome abnormalities for prenatal diagnosis of pregnant women more accurately and provides more comprehensive information for prenatal diagnosis to reduce birth defects.

This study aimed to evaluate the use of high-throughput sequencing (HTS) technology to detect chromosomes in chorionic villus samples of missed abortion embryos and investigate its utility in the genetic diagnosis of missed abortion.HTS was used to assess chorionic villus samples obtained from 169 patients with missed abortions from August 2020 to March 2022, at the Second Affiliated Hospital of Guangxi Medical University. The test results were statistically analyzed. To investigate the impact of advanced age on the incidence of chromosomal abnormalities, the patients were divided into two groups: elderly (≥35 years) and nonelderly pregnant women (35 years).(1) Among the samples of 169 patients, 100 (59.17%) cases of chromosomal abnormalities were detected. Among these 100, 90 (90%) had chromosomal numerical abnormalities and 10 (10%) had chromosomal structural abnormalities. (2) Chromosomal numerical abnormality was abnormalities mainly included aneuploidy (92.22%, 83/90), with trisomy (62.22%, 56/90) and monosomy (22.22%, 20/90) accounting for the majority. The top three numerical abnormalities included 18 cases of Turner syndrome (monosomy X; 20%, 18/90), 10 cases of trisomy 16 (11.11%, 10/90), and 10 cases of trisomy 22 (11.11%, 10/90). (3) Villous chromosomal abnormalities were found in 48 (70.59%) elderly pregnant women, and 52 (51.48%) nonelderly pregnant women, with statistically significant differences (p0.05).(1) Chromosomal abnormality is an important cause of missed abortion, it majorly includes chromosomal numerical abnormality, of which most cases are of aneuploidy. (2) Advanced age may increase the risk of embryonic chromosomal abnormalities. (3) Villus chromosome detection using HTS has a positive value and can be used for analyzing and determining the causes of missed abortion.

Physics and Astronomy (miscellaneous) ,Instrumentation - Abstract
A passively mode-locked erbium-doped fiber laser with a saturable absorber (SA) based on a tapered graded-index multimode fiber with zinc oxide coating is proposed and demonstrated in this paper. The device is also a platform supporting various types of solitons outputs. The conventional solitons with center wavelength of 1558.86 nm, pulse width of 537 fs, and signal-to-noise ratio of 61.27 dB are generated at the repetition frequency of 18.37 MHz. By adjusting the polarization controller and increasing pump power, tightly and loosely bound solitons and two-fold solitons can be generated. The pulse trains of tightly bound solitons exhibit the separation of 1.91 ps, the pulse width of ∼707 fs, and centered at 1560 nm, whereas the pulse separation of loose bound solitons is 18.06 ps. Such a SA is easy in fabrication and highly stable in operation and can enrich the exploration of multi-soliton complexes.

The aim of the study was to analyze the pregnancy outcomes of patients with pulmonary arterial hypertension to provide a reference for clinical diagnosis and treatment.Clinical data of 94 patients with a pregnancy complicated by pulmonary hypertension were retrospectively analyzed. The means and percentages of the pregnancy outcomes were calculated, and the analysis of variance, Chi-square test, and Fisher's exact test were applied for comparison.The pregnancy outcomes were less favorable in the severe pulmonary arterial hypertension group compared to the mild and moderate groups. The more severe the pulmonary arterial hypertension, the worse the heart function. A poorer heart function was associated with a poorer prognosis across different pregnancy outcomes.A pregnancy with more severe pulmonary arterial hypertension and worse cardiac function has a poorer maternal and infant prognosis and pregnancy outcome. Cesarean section is the preferred delivery method for patients with severe pulmonary arterial hypertension, whereas vaginal delivery is preferred for patients with mild or moderate pulmonary arterial hypertension and good cardiac function.

The northwestern Pacific Ocean and South China Sea are where tropical cyclones occur most frequently. Many climatologists also study the formation of Pacific Ocean warm pools and typhoons in this region. This study collected data of paleotyphoons found in China's official historical records over the past 2000 years that contained known typhoon activity reports. The collected data are then subjected to statistical analyses focusing on typhoon activity in coastal regions of southeastern China to garner a better understanding of the long-term evolution of moving paths and occurrence frequency, especially regarding those typhoons making landfall in mainland China. We analyzed the data with the year and month of each typhoon event, as well as the number of events in a 10-year period. The result shows that (1) north–southward migration of typhoon paths corresponds to the north–southward migration of the Intertropical Convergence Zone (ITCZ) during the Medieval Warm Period (MWP) and Little Ice Age (LIA) and (2) paleotyphoons made landfall in mainland China 1 month earlier during the MWP than during the LIA. This implies a northward shift in ITCZ during the MWP. Typhoons tend to make landfall in Japan during El Niño-like periods and strike the southern coastal regions of China during La Niña-like stages. According to paleotyphoon records over the last 2000 years, typhoons made landfall in southeastern China frequently around 490–510, 700–850, and after 1500 CE The number of typhoons striking Guangdong Province peaked during the coldest period in 1660–1680 CE; however, after 1700 CE, landfall has migrated farther north. The track of tropical cyclones (TCs) in the northwestern Pacific Ocean is affected by the North Atlantic Oscillation (NAO) and the Pacific Decadal Oscillation (PDO), which shows a nearly 30-year and a 60-year cycle during the LIA.

- Abstract
The decay ψ′→π+π−π0 is analyzed using a sample of 14 million ψ′ events taken with the BESII detector at the BEPC, and the branching fraction is measured to be B(ψ′→π+π−π0)=(18.1±1.8±1.9)×10−5. A partial wave analysis is carried out using the helicity amplitude method. ψ′→ρ(770)π is observed, and the branching fraction is measured to be B(ψ′→ρ(770)π)=(5.1±0.7±1.1)×10−5, where the first error is statistical and the second one is systematic. A high mass enhancement with mass around 2.15 GeV/c2 is also observed. Attributing this enhancement to the ρ(2150) resonance, the branching fraction is measured to be B(ψ′→ρ(2150)π→π+π−π0)=(19.4±2.5−3.4+11.5)×10−5. The results will help in the understanding of the longstanding “ρπ puzzle” between J/ψ and ψ′ hadronic decays.

We report on the results of a radiation campaign with neutrons and protons of Low Gain Avalanche Detectors (LGAD) produced by Hamamatsu (HPK) as prototypes for the High-Granularity Timing Detector (HGTD) in ATLAS. Sensors with an active thickness of 50μm were irradiated in steps of roughly 2 × up to a fluence of 3 ×1015neqcm−2 . As a function of the fluence, the collected charge and time resolution of the irradiated sensors will be reported for operation at −30 °C. We report on the results of a radiation campaign with neutrons and protons of Low Gain Avalanche Detectors (LGAD) produced by Hamamatsu (HPK) as prototypes for the High-Granularity Timing Detector (HGTD) in ATLAS. Sensors with an active thickness of 50~$\mu$m were irradiated in steps of roughly 2$\times$ up to a fluence of $3\times10^{15}~\mathrm{n_{eq}cm^{-2}}$. As a function of the fluence, the collected charge and time resolution of the irradiated sensors will be reported for operation at $-30^{\circ}$.

Given that mobile phone photography has increased dramatically in popularity, people’s social networking behaviors are becoming more and more visual. Numerous image-based applications and social media are taking advantage of this growing popularity of visual content viewing, editing, and sharing, creating a new phenomenon, image-based social networking. Many image-based social apps are developed as multi-purpose systems, offering a variety of kinds of value to their users. This study proposes three kinds of mobile value – hedonic, utilitarian and sociability – to measure users’ perceptions of image-based apps, and explores how the three kinds of value impact user satisfaction and long-term behavioral intentions. The proposed model was empirically validated using a field survey of 500+ respondents. Both hedonic and sociability value can be provided by an image-based app, but not the utilitarian value, which can increase users’ willingness to pay. The resulting knowledge supports the understanding of various kinds of value by pointing out their different effects on continuance intention and willingness-to-pay. The results also indicate that men and women are affected by different kinds of mobile value when considering using an image-based app. The value that men perceive from an image-based app is generally lower than that perceived by women. Because the value configuration of an app will characterize its market position, the research findings provide implications for app vendors to develop their marketing strategy and to design the best monetization model based on the value configuration of their products.

The aim of this study was to investigate the role of miR-144-3p in the proliferation and metastasis capacity of pediatric Wilms' tumor (WT) cells and to explore the underlying mechanism.The quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) was performed to measure the expression level of miR-144-3p in pediatric WT tissues and cell lines (G401). A bioinformatics software was utilized to predict the interaction between miR-144-3p and Girdin. Subsequently, the interaction was further verified by dual luciferase reporter (DLR) gene assay and Western blot. The proliferation and colony formation ability of G401 cells were examined by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) and colony formation assay, respectively. Finally, the effect of miR-144-3p on cell invasion and migration was analyzed by transwell assay.In the current study, we found that the expression level of miR-144-3p was significantly reduced in pediatric WT tissues and cells, whereas Girdin expression was upregulated. On-line target gene prediction software was applied to screen Girdin, which was considered as a downstream target gene of miR-144-3p. The interaction between miR-144-3p and Girdin was further verified by dual Luciferase reporter gene assay and Western blot. Subsequent experiments demonstrated that the proliferation and metastasis ability of cells was remarkably suppressed after up-regulating the expression of miR-144-3p. However, an addition of Girdin could reverse the effect of miR-144-3p.MiR-144-3p, which was up-regulated in pediatric WT, might inhibit the proliferation and metastasis of the cells by directly targeting Girdin. This further indicated that miR-144-3p could be a potential therapeutic target for the treatment of pediatric WT.

Dihadron azimuthal correlations containing a high transverse momentum ( ) trigger particle are sensitive to the properties of the nuclear medium created at RHIC through the strong interactions occurring between the traversing parton and the medium, i.e. jet-quenching. Previous measurements revealed a strong modification to dihadron azimuthal correlations in Au+Au collisions with respect to p+p and d+Au collisions. The modification increases with the collision centrality, suggesting a path-length or energy density dependence to the jet-quenching effect. This paper reports STAR measurements of dihadron azimuthal correlations in mid-central (20%-60%) Au+Au collisions at GeV as a function of the trigger particle's azimuthal angle relative to the event plane, . The azimuthal correlation is studied as a function of both the trigger and associated particle . The subtractions of the combinatorial background and anisotropic flow, assuming Zero Yield At Minimum (ZYAM), are described. The correlation results are first discussed with subtraction of the even harmonic (elliptic and quadrangular) flow backgrounds. The away-side correlation is strongly modified, and the modification varies with , with a double-peak structure for out-of-plane trigger particles. The near-side ridge (long range pseudo-rapidity correlation) appears to drop with increasing while the jet-like component remains approximately constant. The correlation functions are further studied with the subtraction of odd harmonic triangular flow background arising from fluctuations. It is found that the triangular flow, while responsible for the majority of the amplitudes, is not sufficient to explain the -dependence of the ridge or the away-side double-peak structure. The dropping ridge with could be attributed to a -dependent elliptic anisotropy; however, the physics mechanism of the ridge remains an open question. Even with a -dependent elliptic flow, the away-side correlation structure is robust. These results, with extensive systematic studies of the dihadron correlations as a function of , trigger and associated particle , and the pseudo-rapidity range , should provide stringent inputs to help understand the underlying physics mechanisms of jet-medium interactions in high energy nuclear collisions.

Amines and amides are important atmospheric organic-nitrogen compounds but high time resolution, highly sensitive, and simultaneous ambient measurements of these species are rather sparse. Here, we present the development of a high-resolution time-of-flight chemical ionization mass spectrometer (HR-ToF-CIMS) method, utilizing protonated ethanol as reagent ions to simultaneously detect atmospheric gaseous amines (C1 to C6) and amides (C1 to C6). This method possesses sensitivities of 5.6–19.4 Hz pptv−1 for amines and 3.8–38.0 Hz pptv−1 for amides under total reagent ion signals of ∼ 0.32 MHz. Meanwhile, the detection limits were 0.10–0.50 pptv for amines and 0.29–1.95 pptv for amides at 3σ of the background signal for a 1 min integration time. Controlled characterization in the laboratory indicates that relative humidity has significant influences on the detection of amines and amides, whereas the presence of organics has no obvious effects. Ambient measurements of amines and amides utilizing this method were conducted from 25 July to 25 August 2015 in urban Shanghai, China. While the concentrations of amines ranged from a few parts per trillion by volume to hundreds of parts per trillion by volume, concentrations of amides varied from tens of parts per trillion by volume to a few parts per billion by volume. Among the C1- to C6-amines, the C2-amines were the dominant species with concentrations up to 130 pptv. For amides, the C3-amides (up to 8.7 ppb) were the most abundant species. The diurnal and backward trajectory analysis profiles of amides suggest that in addition to the secondary formation of amides in the atmosphere, industrial emissions could be important sources of amides in urban Shanghai. During the campaign, photo-oxidation of amines and amides might be a main loss pathway for them in daytime, and wet deposition was also an important sink.

Online social media is transforming the way customers communicate and exchange product information with others. Consumers increasingly rely on the opinions and recommendations from social media members when making purchasing decisions. However, information received from social media may have different meanings and social implications for consumers. Based on the theory of informational social influence and heuristic-systematic model (HSM), we develop a model to understand the relative importance of informational social influence, normative social influence, and perceived information quality on the consumer’s social shopping intention under different levels of product involvement. The results of the structural equation modeling (SEM) using a sample of 503 consumers in the Facebook brand fan pages indicate that social influences have a greater impact on the consumer’s social shopping intention than perceived information quality. Three social interactional factors (perceived similarity, familiarity, and expertise) have a positive effect on social shopping intention via the mediation of informational, normative social influence and perceive information quality. The multiple-group analysis suggests that high product-involved consumers are motivated to exert more cognitive effort to evaluate the product information. In contrast, low product-involved consumers are more susceptible to informational social influence. We draw on these findings to offer implications for researchers and practitioners.

Using Eu2O3 as raw material, anhydrous ethanol as solvent system, 1-(4-Methoxyphenyl)-3-(4-tert-butylphenyl)-1,3-propanedione (Avobenzone) as first ligands and triphenylphosphane oxide (TPPO) as second ligands, the rare earth complex Eu(Avobenzone)3TPPO has been successfully prepared by precipitation method. The Eu(Avobenzone)3TPPO were characterized by fluorescence spectrum analysis (FS), Fourier transform infrared spectroscopy(FT-IR) and color coordinate calculation. The thermal stability of Eu(Avobenzone)3TPPO was studied by thermogravimetry differential scanning calorimetry (TG-DSC). The results showed that Eu(Avobenzone)3TPPO emitted strong red characteristic fluorescence, the optimal excitation wavelength was 397nm, the characteristic emission wavelength was 612 nm, and the color coordinates were (0.66, 0.34). Eu(Avobenzone)3TPPO decomposes at about 200°C it shows good thermal stability.

In order to improve the particle identification capability, the Beijing Spectrometer (BESIII) collaboration has upgraded the End-cap Time-Of-Flight detector (ETOF) based on Multi-gap Resistive Plate Chamber (MRPC) technology. In this paper, the design and engineering development of each part of the project are reported. There are 72 MRPC modules, forming 2 rings. Adjacent modules are staggered placed to avoid dead regions. Each MRPC module contains 12-layer thin gaps to get fast signals with high efficiency and 12 strips to readout the induced signals from two ends, effectively reducing the timing uncertainties from the scattering and positioning. Also, the analog–digital conversion is done near the MRPC and only the digital signals are transferred through thin coax cables, ensuring good signal-to-noise ratio. The complex electromagnetic noises in the BESIII colliding area are well shielded to protect the tiny signals from the MRPC. After careful correction and calibration, the total time resolution of upgraded ETOF system is 65ps.

The key element providing hadron identification at incident energies between 2 and 11 AGeV in heavy-ion collisions at the SIS100 accelerator is a Time-of-Flight (TOF) wall covering the polar angular range from $2.5^0$ --$25^0$ and full azimuth. CBM is expected to be operational in the year 2024 at the Facility for Anti-proton and Ion Research (FAIR) in Darmstadt, Germany. The existing conceptual design foresees a 120 m^2 TOF-wall composed of Multi-gap Resistive Plate Chambers (MRPC) which is subdivided into a high rate region, a middle rate region and a low rate region. The MRPC3b Multistrip-MRPCs, foreseen to be integrated in the low rate region, have to cope with charged particle fluxes up to 1 kHz/cm2 and therefore will be constructed with thin float glass (0.28 mm thickness) as resistive electrode material. In the scope of the FAIR phase 0 program it is planned to install about 36 \% of the MRPC3b counters in the east endcap region of the STAR experiment at BNL as an upgrade for the Beam Energy Scan campaign (BESII) in 2019/2020., 9 pages, 11 figures, Proceedings for the XIV Workshop on Resistive Plate Chambers and related detectors

This research applied an investment model to investigate the career commitment of IT professionals. We explore why some unfavorable careers persist and why some favorable careers end. Self-reported data from MIS departments of Taiwan's top-1000 large-scale companies were collected to test our hypotheses. The results suggested that an IT professional's career commitment is primarily determined by career satisfaction. In addition, the threat of professional obsolescence exerted more influence on individuals with low professional self-efficacy. Finally, career satisfaction appeared the most important antecedent for individuals with positive valence. In contrast, the career commitment for individuals with negative valence was largely driven by non-voluntary dependence. The implications for practitioners and scholars are discussed.

A directional bend sensor based on selectively infiltrated photonic crystal fiber is demonstrated. The device is fabricated by use of femtosecond laser micromachining technique and fusion splicing of photonic crystal fiber with single-mode fiber. By infiltrating refractive index liquid into one of the air holes of the photonic crystal fiber, the core mode can be coupled into the higher order liquid rod mode, thus producing a resonant dip in the transmission spectrum of the device. Such a dip wavelength is sensitive to both the bending curvature and the direction, and has a linear response to curvature within a large range from 0 to 10.7 m $^{-1}$ .

In order to further enhance the particle identification capability of the Beijing Spectrometer (BESIII), it is proposed to upgrade the current end-cap time-of-flight (eTOF) detector with multi-gap resistive plate chamber (MRPC). The prototypes, together with the front end electronics (FEE) and time digitizer (TDIG) module have been tested at the E3 line of Beijing Electron Positron Collider (BEPCII) to study the difference between the single and double-end readout MRPC designs. The time resolutions (sigma) of the single-end readout MRPC are 47/53 ps obtained by 600 MeV/c proton/pion beam, while that of the double-end readout MRPC is 40 Ps (proton beam). The efficiencies of three MRPC modules tested by both proton and pion beam are better than 98%. For the double-end readout MRPC, no incident position dependence is observed. (C) 2014 Elsevier B.V.

We report the timing and spatial resolution from the Muon Telescope Detector (MTD) installed in the STAR experiment at RHIC. Cosmic ray muons traversing the STAR detector have an average transverse momentum of 6 GeV/c. Due to their very small multiple scattering, these cosmic muons provide an ideal tool to calibrate the detectors and measure their timing and spatial resolution. The values obtained were ~100 ps and ~1-2 cm, respectively. These values are comparable to those obtained from cosmic-ray bench tests and test beams., Comment: 15 pages, 10 figures

Aims To report the annual incidence rate and the socio-demographic and clinical characteristics of childhood Type 1 diabetes in Taiwan in the period 2003–2008. Methods A total of 1306 incident cases of childhood (0–14 years) Type 1 diabetes were identified from Taiwan's National Health Insurance claim datasets from the period 2003–2008. The temporal trend of the incidence rate of Type 1 diabetes and the features of hospitalizations in the first year after diagnosis were investigated. The associations of patient characteristics, child population density and the urbanization level of the residential areas with the risk of Type 1 diabetes were assessed using Poisson regression analysis. Results The annual incidence rate was stable, irrespective of age and gender, with a mean annual incidence rate of 5.3 per 100 000 children. Girls were more likely than boys to develop Type 1 diabetes (6.0 vs 4.7 per 100 000 children) and the incidence rate increased with age. There was no apparent geographic variation in the incidence rates. Despite the 60% decrease in the rate of admission (from 11.0 to 5.8%) over the study period, ketoacidosis remained the major diabetes complication leading to admission for childhood Type 1 diabetes. The multivariate analysis suggested that female gender and older age were significant predictors of the incidence of Type 1 diabetes, whereas the population density of children and the urbanization levels of the residential areas were not. Conclusions Girls and older children should receive particular attention when formulating preventive strategies targeting Type 1 diabetes. Additionally, clinicians should still carefully optimize the management of children with Type 1 diabetes to further reduce the occurrence of ketoacidosis.

Up till now, China has not enacted any legal mechanisms governing certification or supervision for ethics committees. This article analyses deficiencies in the protection of subjects in clinical drug trials under China's current laws and regulations; it emphasizes that investigators, as practitioners who have direct contact with subjects, play significant roles in protecting and safeguarding subjects' rights and interests. The paper compares the status quo in China in this area to that of other countries and discusses ways China might enhance the protection of rights and interests of trial subjects, such as enhancing the ethical awareness of investigators through training, improving laws and regulations, and strengthening the communication between investigators and ethics committees.

The Compressed Baryonic Matter spectrometer (CBM) is expected to be operational in the year 2024 at the Facility for Anti-proton and Ion Research (FAIR) in Darmstadt, Germany. CBM aims to study strongly interacting matter under extreme conditions. The key element providing hadron identification is the Time-Of-Flight (TOF) wall at incident energies between 2 and 10 AGeV . The TOF-wall covers the polar angular range from 2.5o–25o and full azimuth. According to the simulation results, the TOF system is required to reach a time resolution of better than 80 ps for the particle identification (PID) under high rate. The existing conceptual design foresees a 120 m2 TOF-wall composed of Multi-gap Resistive Plate Chambers (MRPC) which is subdivided into a high rate region, a middle rate region and a low rate region. The flux in the low rate region is around 1 kHz/cm2. For this region, we developed a Multistrip-MRPC using thin float glass as the resistive electrode. In this paper, we present the design of these MRPC prototypes and the results obtained during the beam test at the E3 line at Beijing Electron-Positron Collider (BEPC).

- Abstract
We report on the crystal growth, structural and spectroscopic investigation of a novel trigonal calcium vanadate crystal, Tm3+:Ca9La(VO4)(7). Polarized absorption, stimulated-emission and gain cross-section spectra are determined for this material. The maximum sigma(SE) corresponding to the F-3(4) -> H-3(6) transition amounts to 1.28 x 10(-20) cm(2) at 1854 nm for sigma-polarization. The measured lifetime of the Tm3+ ions in the F-3(4) state is 1.19 ms. The Judd-Ofelt analysis performed yielded intensity parameters of Omega(2) = 4.682, Omega(4) = 0.659 and Omega(6) = 0.475 [10(-20) cm(2)]. The polarized Raman spectra indicate a strong and broad band centered at 867 cm(-1). Owing to the disordered nature of Ca9La(VO4)(7), the Tm3+ ions exhibit a broad and smooth gain profile at similar to 2 mu m. The spectroscopic properties of Tm3+:Ca9La(VO4)(7) are very promising for broadly tunable and ultrashort pulse lasers near 2 mu m. (C) 2017 Optical Society of America

A search is performed for a Higgs boson produced in association with a Z boson and decaying into two photons, using the L3 data collected at LEP at a centre-of-mass energy of 189 GeV. All decay modes of the Z are considered. No signal is observed and limits on the branching fraction of the Higgs boson decay into two photons as a function of the Higgs mass are derived assuming a Standard Model production rate. A lower limit on the mass of a fermiophobic Higgs is set at 94.9 GeV at 95% confidence level., Facultad de Ciencias Exactas

The Standard Model Higgs boson is searched for in 233.2 pb−1 of data collected by the L3 detector at centre of mass energies from 192 GeV to 202 GeV. These data are consistent with the expectations of Standard Model processes and no evidence of a Higgs signal is observed. A lower limit on the mass of the Standard Model Higgs boson of 107.0 GeV is set at the 95% confidence level., Facultad de Ciencias Exactas

The S matrix ansatz is a rigorously model independent approach to describe the cross-sections and asymmetries in e+e- annihilation. Using the cross-sections and asymmetries measured with the L3 detector during the 1990 and 1991 running period, we determine the mass and the width of the Z boson, the contributions of the Z exchange and of the yZ interference. Including the polarization of the t lepton in the analysis, the leptonic helicity amplitudes of the scattering process are determined assuming lepton universality. The results are compared with other model independent ansatzes as realized in ZFITTER. A systematic bias of the Z mass due to the yZ interference term is detected, which leads to an underestimation of the error on mz for model independent determinations., Facultad de Ciencias Exactas

The process eqeyaWqWyg is analysed using the data collected with the L3 detector at LEP at a centre-of-mass energy of 188.6 GeV, corresponding to an integrated luminosity of 176.8 pby1 . Based on a sample of 42 selected WqWy candidates containing an isolated hard photon, the WqWyg cross section, defined within phase-space cuts, is measured to q y be: s WW s290"80"16 fb, consistent with the Standard Model expectation. Including the process e e anngg, limits g are derived on anomalous contributions to the Standard Model quartic vertices WqWygg and WqWyZg at 95% CL: y0.043 GeVy2-a rL2-0.043 GeVy2 , y0.08 GeVy2-a rL2-0.13 GeVy2 , y0.41 GeVy2-a rL2-0.37 GeVy2, Facultad de Ciencias Exactas

We present results obtained from a study of the structure of hadronic events recorded by the L3 detector at various centre-of-mass energies. The distributions of event shape variables and the energy dependence of their mean values are measured from 30 GeV to 189 GeV and compared with various QCD models. The energy dependence of the moments of event shape variables is used to test a power law ansatz for the non-perturbative component. We obtain a universal value of Ž 2 the non-perturbative parameter a s 0.537 ± 0.073. From a comparison with resummed O(αs2)QCD calculations, we 0 s determine the strong coupling constant at each of the selected energies. The measurements demonstrate the running of αs as expected in QCD with a value of αs(mZ) = 0.1215 ± 0.0012 (exp) ± 0.0061 (th)., Facultad de Ciencias Exactas
