TL;DR: In this article, the authors present the final results obtained by the MACRO experiment in the search for GUT magnetic monopoles in the penetrating cosmic radiation, for the range 4×10 −5 <β < 1.
Abstract: We present the final results obtained by the MACRO experiment in the search for GUT magnetic monopoles in the penetrating cosmic radiation, for the range 4×10 −5 <β< 1. Several searches with all the MACRO sub-detectors (i.e. scintillation counters, limited streamer tubes and nuclear track detectors) were performed, both in stand alone and combined ways. No candidates were detected and a 90% Confidence Level (C.L.) upper limit to the local magnetic monopole flux was set at the level of 1.4 × 10 −16 cm −2 s −1 sr −1 . This result is the first experimental limit obtained in direct searches which is well below the Parker

TL;DR: In this paper, the authors studied the growth and development of "charged particle jets" produced in proton-antiproton collisions at 1.8 TeV over a transverse momentum range from 0.5 GeV/c to 50 GeV /c.
Abstract: The growth and development of "charged particle jets" produced in proton-antiproton collisions at 1.8 TeV are studied over a transverse momentum range from 0.5 GeV/c to 50 GeV/c. A variety of leading (highest transverse momentum) charged jet observables are compared with the QCD Monte Carlo models HERWIG, ISAJET, and PYTHIA. The models describe fairly well the multiplicity distribution of charged particles within the leading charged jet, the size of the leading charged jet, the radial distribution of charged particles and transverse momentum around the leading charged jet direction, and the momentum distribution of charged particles within the leading charged jet. The direction of the leading "charged particle jet" in each event is used to define three regions of eta-phi space. The "toward" region contains the leading "charged particle jet," while the "away" region, on the average, contains the away-side jet. The "transverse" region is perpendicular to the plane of the hard 2-to-2 scattering and is very sensitive to the "underlying event" component of the QCD Monte Carlo models. HERWIG, ISAJET, and PYTHIA with their default parameters do not describe correctly all the properties of the "transverse" region.

TL;DR: In this paper, a photonic high-frequency capacitance-voltage (HF C-V) response of metal-oxide semiconductor (MOS) capacitors is reported for the analysis of interface states in MOS systems.
Abstract: A new characterization method based on the photonic high-frequency capacitance-voltage (HF C-V) response of metal-oxide semiconductor (MOS) capacitors is reported for the analysis of interface states in MOS systems. An optical source with a photon energy less than the silicon band-gap (h/spl nu/ = 0.799 eV < E/sub g/ = 1.11 eV) is employed for the photonic characterization of interface states (Bit) distributed in the photoresponsive energy band (E/sub c/ h/spl nu/ < E/sub it/ < E/sub c/) in NMOS capacitors with a polysilicon gate. Assuming a uniform distribution of the trap levels, the density of interface states (D/sub it/) was observed to be D/sub it/ 1-5 /spl times/ 10/sup 11/ eV/sup -1/ cm/sup -2/ in the photoresponsive energy band.

TL;DR: In this paper, an advanced model to explain the current spreading phenomenon of a conventional GaN-based light-emitting diode is presented, and an equivalent circuit consisting of the two lateral resistance components of the p-transparent electrode and the n-type layer is proposed.
Abstract: An advanced model to explain the current spreading phenomenon of a conventional GaN-based light-emitting diode is presented. For this work, an equivalent circuit, consisting of the two lateral resistance components of the p-transparent electrode and the n-type layer is proposed. Theoretical calculations clearly reveal that the current density crowds near the n or p pads according to the device parameters and has an exponential behavior as a function of the lateral length. Based on these results, appropriate device parameters including the critical transparent-electrode thickness were determined, leading to a perfectly uniform current distribution. It was even possible to demonstrate the ideal device geometry without the need for a transparent electrode such as an interdigitated structure.

TL;DR: The measured angular distribution of the muons in the Upsilon(1S) rest frame is consistent with unpolarized meson production, as well as on the Upsilonian polarization in p p macro collisions at square root of s = 1.8 TeV.
Abstract: We report on measurements of the Y(1S), Y(2S), and Y(3S) differential cross sections (d(2)sigma/dp(T)dy)(\y\ collisions at roots = 1.8 TeV using a sample of 77+/-3 pb(-1) collected by the collider detector at Fermilab. The three resonances were reconstructed through the decay Y-->mu(+)mu(-) . The measured angular distribution of the muons in the Y(1S) rest frame is consistent with unpolarized meson production.

TL;DR: In this paper, a three-dimensional fluid code (FL3P) was developed to analyze the discharge characteristics of an alternating current plasma display panel (AC PDP) and optimize it further.
Abstract: In order to understand the discharge characteristics in an alternating current plasma display panel (ac PDP) and optimize it further, a three-dimensional fluid code (FL3P) has been developed. Using this simulator, various three-dimensional features of discharges are investigated in the sustain mode of PDP. First, the striations of wall charge are observed at both the anode and cathode side. Second, the local efficiency is obtained as a function of position. It is mainly divided into the anode region and the cathode region and highest near the anode center. Finally, the effects of various three-dimensional parameters are studied. As one of the examples showing the effect of electrode shaping, the discharge characteristics of a T-shaped electrode cell are compared with those of a conventional cell. The phosphor on barrier ribs contributes to over 44% of the total luminance, but barrier ribs themselves do not play an important role in the overall discharge efficiency. Address electrode width is not always pr...

TL;DR: Results suggest that COX-2 expression may play an important role in the evolution of colon carcinogenesis, however, further studies are needed to determine the prognostic relevance of COx-2.
Abstract: Background. Overexpression of cyclooxygenase-2 (COX-2) has been demonstrated in various human cancers, including colorectal cancer. Thus, overexpression of COX-2 may be involved in the growth and progression of cancer, and this may have prognostic significance. Aim. The aim of our study is to evaluate the expression of COX-2 in colorectal cancer tissue, and to examine the relationship of its expression to various clinicopathological parameters and patient survival. Methods. Formalin-fixed, paraffin-embedded tissue blocks were obtained from 60 patients who underwent surgery for colorectal carcinoma in 1995 at the Chonnam National University Hospital in Gwangju, Korea. We have used an immunohistochemical technique to localize COX-2 in colorectal carcinoma tissues. Results. Immunohistochemical staining of the colorectal cancer specimens demonstrated that COX-2 expression was localized to the carcinoma cells and was not detectable in the stromal compartment of the cancers. The COX-2 immunostaining pattern was predominantly homogenous, and perinuclear cytoplasmic within the tumors. Normal colonic epithelium adjacent to the tumor showed no staining for COX-2. The COX-2 protein was detected in 70% (42/60) of colorectal carcinoma tissues. However, no significant correlation was found between COX-2 expression and various clinicopathological parameters, including histologic grade, tumor size, depth of invasion, lymph node metastasis, distant metastasis, or stage. Furthermore, COX-2 expression did not correlate with patient survival (p=0.401). Conclusion. These results suggest that COX-2 expression may play an important role in the evolution of colon carcinogenesis. However, further studies are needed to determine the prognostic relevance of COX-2.

Abstract: A menu displaying method in a mobile terminal. When a user opens a menu function, a list of menu items is displayed on a display. Upon user selection of a menu item from the list, the selected menu item is perceivably displayed. It is determined whether a sub-menu of the menu item has been set as status information of the menu item. If the sub-menu has been set as the status information, a bubble window having the status information is displayed near the menu item.

TL;DR: In this article, the authors present a study of p (p) over bar collisions at roots=1800 and 630 GeV collected using a minimum bias trigger by the CDF experiment in which the data set is divided into two classes corresponding to "soft" and "hard" interactions.
Abstract: We present a study of p (p) over bar collisions at roots=1800 and 630 GeV collected using a minimum bias trigger by the CDF experiment in which the data set is divided into two classes corresponding to "soft" and "hard" interactions. For each subsample, the analysis includes measurements of the multiplicity, transverse momentum (p(T)) spectrum, and the average p(T) and event-by-event p(T) dispersion as a function of multiplicity. A comparison of results shows distinct differences in the behavior of the two samples as a function of the center of mass (c.m.) energy. We find evidence that the properties of the soft sample are invariant as a function of c.m. energy.

TL;DR: In this article, the authors measured the cross sections d(2)sigma/dP(T)deta for production of isolated direct photons in p (p) over bar collisions at two different center-of-mass energies, 1.8 TeV and 0.63 TeV.
Abstract: We have measured the cross sections d(2)sigma/dP(T)deta for production of isolated direct photons in p (p) over bar collisions at two different center-of-mass energies, 1.8 TeV and 0.63 TeV, using the Collider Detector at Fermilab. The normalization of both data sets agrees with the predictions of quantum chromodynamics for a photon transverse momentum (P-T) of 25 GeV/c, but the shapes versus photon P-T do not. These shape differences lead to a significant disagreement in the ratio of cross sections in the scaling variable x(T)(=2P(T)/roots). This disagreement in the x(T) ratio is difficult to explain with conventional theoretical uncertainties such as scale dependence and parton distribution parametrizations.

TL;DR: In this paper, the effects of a catalysis process in the MACRO detector were investigated using a dedicated analysis and the authors obtained new magnetic monopole flux upper limits at the level of ∼ 3 · 10 −16 cm −2 s −1 sr −1 for 1.1 · 10−4 ≤| β |≤ 5· 10 −3, based on the search for catalysis events.
Abstract: The interaction of a Grand Unification Magnetic Monopole with a nucleon can lead to a barion- number violating process in which the nucleon decays into a lepton and one or more mesons (catalysis of nucleon decay). In this paper we report an experimental study of the effects of a catalysis process in the MACRO detector. Using a dedicated analysis we obtain new magnetic monopole (MM) flux upper limits at the level of ∼ 3 · 10 −16 cm −2 s −1 sr −1 for 1.1 · 10 −4 ≤| β |≤ 5 · 10 −3 , based on the search for catalysis events in the MACRO data. We also analyze the dependence of the MM flux limit on the catalysis cross section.

TL;DR: In this paper, the growth of transparent conducting indium tin oxide (ITO) films on the porous silicon (PS) layers was investigated by atomic force microscopic (AFM), SEM and X-ray diffraction (XRD) techniques.
Abstract: Transparent conducting indium tin oxide (ITO) films are deposited by rf-sputtering at a constant power of 400 W in Ar atmosphere on the porous silicon (PS) layers anodized on p-type (100) Si wafers. At three successive stages of deposition for 10, 20 and 30 min, respectively, the growth of ITO on PS is thoroughly investigated by atomic force microscopic (AFM), SEM and X-ray diffraction (XRD) techniques. The features of growth on other substrates like single crystal p-type (100) silicon, quartz and glass are also taken into consideration. The influence of ITO microstructure on the PS interface is correlated with the electrical and luminescent behavior of the resulting heterojunction diode structure.

TL;DR: In this article, the authors used a neural network approach to reconstruct the muon energy for E μ GeV, which can be used further to obtain an estimate of the energy of muons crossing the detector.
Abstract: Muon energy measurement represents an important issue for any experiment addressing neutrino-induced up-going muon studies. Since the neutrino oscillation probability depends on the neutrino energy, a measurement of the muon energy adds an important piece of information concerning the neutrino system. We show in this paper how the MACRO limited streamer tube system can be operated in drift mode by using the TDCs included in the QTPs, an electronics designed for magnetic monopole search. An improvement of the space resolution is obtained, through an analysis of the multiple scattering of muon tracks as they pass through our detector. This information can be used further to obtain an estimate of the energy of muons crossing the detector. Here we present the results of two dedicated tests, performed at CERN PS-T9 and SPS-X7 beam lines, to provide a full check of the electronics and to exploit the feasibility of such a multiple scattering analysis. We show that by using a neural network approach, we are able to reconstruct the muon energy for E μ GeV . The test beam data provide an absolute energy calibration, which allows us to apply this method to MACRO data.

TL;DR: It is suggested that the association between small-bowel adenocarcinomas and neurofibromatosis may not be fortuitous, and that small- Bowel AdenOCarcinoma should be considered, in particular.
Abstract: It is well known that patients with neurofibromatosis have an increased incidence of various neoplasms, most of these being tumors of neural-crest origin, including neurofibromas, leiomyomas, ganglioneuromas, paragangliomas, and carcinoids. However, the occurrence of small-bowel adenocarcinoma is rare. In this article, we report a patient with small-bowel adenocarcinoma, the seventh such reported case. We include a review of the literature and a brief discussion of the implications of this association. We suggest that the association between small-bowel adenocarcinomas and neurofibromatosis may not be fortuitous, and that small-bowel adenocarcinoma should be considered, in particular, in the differential diagnosis of gastrointestinal symptoms in patients with neurofibromatosis. Also, a definite histologic diagnosis must be made, with the employment of special staining techniques, because of the differing prognoses for various cell types.

TL;DR: In this article, the proton radiation tolerance of a 035 /spl mu/m SOI technology on UNIBOND material was investigated and the radiation response was characterized by threshold-voltage shifts of the front-gate and back-gate transistors.
Abstract: We investigate the proton radiation tolerance of a 035 /spl mu/m SOI technology on UNIBOND material The radiation response is characterized by threshold-voltage shifts of the front-gate and back-gate transistors An increase of the front-gate threshold voltage is observed on the n-channel MOSFETs after irradiation and is attributed to radiation-induced interface states at the front-gate oxide/silicon interface A double g/sub m/ peak behavior is observed on the back-gate g/sub m/-V/sub GS/ curves for both n- and p-channel MOSFETs and is attributed to silicon/back-gate oxide interface traps with a delta-function-like distribution in the energy gap The results suggest this 035 /spl mu/m technology on UNIBOND material performs well in a proton-radiation environment

TL;DR: In this paper, the strange and flavor-singlet electric and magnetic form factors of the nucleon were investigated in the framework of the SU(3) chiral quark-soliton model.
Abstract: We investigate the strange and flavor-singlet electric and magnetic form factors of the nucleon within the framework of the SU(3) chiral quark-soliton model. Isospin symmetry is assumed and the symmetry-conserving SU(3) quantization is employed, rotational and strange quark mass corrections being included. For the experiments G0, A4, and HAPPEX-II we predict the quantities $G^{0}_E + \beta G^{0}_M$ and $G^{\rm s}_E + \beta G^{\rm s}_M$. The dependence of the results on the parameters of the model and the treatment of the Yukawa asymptotic behavior of the soliton are investigated.

TL;DR: A new technique using electric resection and electrovaporization of fibrotic tissue for implantation of penile prosthesis in a patient with severe corporeal fibrosis is introduced.
Abstract: Implantation of a penile prosthesis in men with complicated fibrosis of corpus cavernosum is very difficult and even impossible. Cavernosal dilation requires sharp intracavernosal dissection to implant prosthesis, however complete removal of the fibrotic tissue is often impossible. We introduce a new technique using electric resection and electrovaporization of fibrotic tissue for implantation of penile prosthesis in a patient with severe corporeal fibrosis.

TL;DR: In this article, a selfconsistent calculation of magnetic phase structure in modulation-doped dilute magnetic III-V semiconductor quantum wells is presented, where the spin-split subband structure is calculated at finite temperature and magnetic-field effects on the carrier-induced magnetism are examined in a weak-field regime.
Abstract: We present a self-consistent calculation of magnetic phase structure in modulation-doped dilute magnetic III-V semiconductor quantum wells. The spin-split subband structure is calculated at finite temperature and magnetic-field effects on the carrier-induced magnetism are examined in a weak-field regime. The exchange correlation of free carriers is shown to enhance the ferromagnetic tendency. And the temperature T t h , below which the system spontaneously becomes fully spin polarized, increases as the doping concentration N a in nonmagnetic barriers increases. Hysteresis loop of the magnetic quantum well predicts that the remnant magnetization is enhanced as one increases the modulation-doped acceptor impurity concentration.

TL;DR: In this article, the first investigation of low energy (1.75 MeV) proton irradiation in SiGe HBT's and discuss proton energy effects was presented.
Abstract: We present the first investigation of low energy (1.75 MeV) proton irradiation in SiGe HBT's and discuss proton energy effects in SiGe HBT technology. The results show that after 1.75 MeV 1 /spl times/ 10/sup 14/ p/cm/sup 2/, a semi-insulating substrate is obtained and the peak quality factor of the monolithic inductors is improved by about 18% at 1.6 GHz. Although large current gain degradation for the SiGe HBT's was observed in the RF bias region after 1 /spl times/ 10/sup 14/ p/cm/sup 2/, the degradation in peak f/sub T/ is only about 11%. Proton energy studies from 1.75 MeV to 200 MeV in SiGe HBT's suggest that the conventional damage factor can be used to estimate energy-dependent proton-induced radiation damage in this technology.

TL;DR: A patient is reported with an accessory bile duct draining into the stomach and the literature pertaining to this condition is reviewed.
Abstract: An accessory bile duct is found in up to 4% of necropsies and is usually a single thin-walled channel that drains a segment of the right lobe of the liver into the common bile duct or, rarely, into the gallbladder. However, accessory bile ducts draining into the gastrointestinal tract are extremely rare. We report a patient with an accessory bile duct draining into the stomach and review the literature pertaining to this condition.

TL;DR: In this paper, the emission characteristics of carbon nanotubes (CNTs) grown on Fe-coated glass using mixed gases of CO and NH 3 were investigated by varying the growth time and growth condition including in situ re-etching and/or re-growth of CNTs.
Abstract: Field emission characteristics of carbon nanotubes (CNTs) grown on Fe-coated glass using mixed gases of CO and NH 3 were investigated by varying the growth time and growth condition including in situ re-etching and/or re-growth of CNTs. An increase in growth time resulted in a reduction of a turn-on electric field. However, additional in situ re-etching and re-growth of CNTs after the initial growth yielded a decrease in the emission current from CNTs with a similar turn-on field to as-grown CNTs.
