Multivariate one-sided tests for multivariate normal and mixed effects regression models with missing data, semi-continuous data and censored data
Creators: name: Zhou, Guohai
Publisher: name: University of British Columbia
Year: 2017

description: In many applications, statistical models for real data often have natural constraints or restrictions on some model parameters. For example, the growth rate of a child is expected to be positive, and patients receiving anti-HIV treatments are expected to exhibit a decline in their viral loads. Hypothesis testing for certain model parameters incorporating the natural constraints is expected to be more powerful than testing ignoring the constraints. Although constrained statistical inference, especially multi-parameter order-restricted hypothesis testing, has been studied in the literature for several decades, methods for models for complex longitudinal data are still very limited. In this thesis, we develop innovative multi-parameter orderrestricted (or one-sided) hypothesis testing methods for modelling the following complex data: (1) multivariate normal data with non-ignorable missing values; (2) semi-continuous longitudinal data; and (3) left censored or truncated longitudinal data due to detection limits. We focus on testing mean parameters in the models, and the approaches are based on the likelihood methods. Some asymptotic results are obtained, and some computational challenges are discussed. Simulation studies are conducted to evaluate the proposed methods. Several real datasets are analyzed to illustrate the power advantages of proposed new tests.

description: A natural dye for dyeing textiles was extracted from Kalanchoe-pinnata leaf powder using aqueous extraction and characterized by determining the radical scavenging activity (%), tannin content, flavonoid and phenolic content, FTIR, and UV-visible absorption analysis. Protein fabrics, i.e., wool, silk, soya, and milk were dyed by optimizing dyeing time, temperature, pH and MLR conditions with and without mordants. The dyed fabrics were assessed for their color strength, fastness properties, ultraviolet protection factor, and antibacterial properties. The result of the study shows that obtained Kalanchoe-pinnata leaf extract has good anti-oxidant properties being 84.92% of radical scavenging activity, possesses good coloration, affinity for textile material and functional properties being high content of tannin, flavonoid, and phenolic compounds. Wool and silk showed very good affinity for the dye extract and fastness behavior followed by soya and milk fabrics. Wool shows ultraviolet protection factor while there is no significant effect on silk, soya, and milk fabrics as these fabrics are very thin in structure. The aqueous extract as well as all the dyed samples also exhibit excellent anti-bacterial activity against S-aurous and E-coli. Thus, Kalanchoe-pinnata leaf extract can be a better sustainable substitute to synthetic dyes for dyeing of protein fabrics.
Magnetic field study for a new generation high resolution mass separator
Creators: name: Marchetto, Marco
Publisher: name: University of British Columbia
Year: 2017

description: The work presented in this thesis is part of the design of the high resolution mass separator for the ARIEL facility under construction at TRIUMF, located in the UBC campus. This new facility, together with the existing ISAC facility, will produce rare isotope beams for nuclear physics experiments and nuclear medicine. The delivery of such beams requires a stage of separation after production to select the isotope of interest. The required separation is expressed in terms of resolving power defined as the inverse of the relative mass difference between two isotopes that need to be separated. The higher the mass the greater the resolving power required. The challenge is the separation of two isobars rather than two isotopes that by definition require a much lower resolving power. A resolving power of twenty thousand is the minimum required to achieve isobaric separation up to the uranium mass. The state of the art for existing heavy ion mass separators is a resolving power in the order of ten thousand for a transmitted emittance of less than three micrometers. The more typical long term operational value is well below ten thousand for larger emittances. The main goal of this project is to develop a mass separator that maintains an operational resolving power of twenty thousand. Different aspects influence the performance of the mass separator; the two main ones are the optics design and the field quality of the magnetic dipole(s) that provides the core functionality of the mass separator. In this thesis we worked from the hypothesis that minimizing the magnetic field integral variation with respect to the design mass resolution is equivalent to minimizing the aberration of the optical system. During this work we investigated how certain geometric parameters influence the field quality, as for example the dependency of the field flatness on the magnet pole gap. We also developed a new technique to control the mesh in the finite element analysis to facilitate particle tracking calculations. Beyond demonstrating our hypothesis, we ultimately produced a final magnet design where the field integral variation is less than one part in one hundred thousand.
Non-collinear Magnetic Order in the Double Perovskites: Double Exchange on a Geometrically Frustrated Lattice

description: Double perovskites of the form A_2BB'O_6 usually involve a transition metal ion, B, with a large magnetic moment, and a non magnetic ion B'. While many double perovskites are ferromagnetic, studies on the underlying model reveal the possibility of antiferromagnetic phases as well driven by electron delocalisation. In this paper we present a comprehensive study of the magnetic ground state and T_c scales of the minimal double perovskite model in three dimensions using a combination of spin-fermion Monte Carlo and variational calculations. In contrast to two dimensions, where the effective magnetic lattice is bipartite, three dimensions involves a geometrically frustrated face centered cubic (FCC) lattice. This promotes non-collinear spiral states and `flux' like phases in addition to collinear anti-ferromagnetic order. We map out the possible magnetic phases for varying electron density, `level separation' epsilon_B - epsilon_B', and the crucial B'-B' (next neighbour) hopping t'.

description: The nuclear states of \bar K and ηare bound by a similar mechanism - the excitations of nucleons to Λ(1405) and N*(1535) resonant states. The observed large differences in binding energies are understood in terms of separation of the involved energies and the resonance positions. The other experimental findings: broad \bar K-mesic and narrow η-mesic states are more difficult to understand. A phenomenological model for η-N interactions is used to explain the suppression of the ηabsorption in light nuclei.

description: The formation of hot subdwarf stars (sdBs), which are core helium-burning stars located on the extended horizontal branch, is still not understood. Many of the known hot subdwarf stars reside in close binary systems with short orbital periods between a few hours and a few days with either M star or white dwarf companions. Common envelope ejection is the most probable formation channel. Among these, eclipsing systems are of special importance because it is possible to constrain the parameters of both components tightly by combining spectroscopic and light curve analyses. We report the discovery of two eclipsing binaries with a brown dwarf (< 0.07 M*) and a 0.15 M* late main sequence star companion in close orbits around sdB stars.

description: The neutron-rich nucleus 74Ni was studied with inverse-kinematics inelastic proton scattering using a 74Ni radioactive beam incident on a liquid hydrogen targetat a center-of-mass energy of 80 MeV. From the measured de-excitation gamma-rays, the population of the first 2+ state was quantified. The angle-integrated excitation cross section was determined to be 14(4) mb. A deformation length of delta = 1.04(16) fm was extracted in comparison with distorted wave theory, which suggests that the enhancement of collectivity established for 70Ni continues up to 74Ni. A comparison with results of shell model and quasi-particle random phase approximation calculations indicates that the magic character of Z = 28 or N = 50 is weakened in 74Ni.

description: Optical imaging is a cornerstone in biological and biomedical sciences. It is imperative to not only obtain high-resolution images but also provide real-time quantification of biological measurement using automated non-invasive imaging solutions. In recent years, the advent of volumetric microscopes, especially laser scanning microscopy (LSM) and quantitative phase microscopy (QPM), has opened up new powerful imaging tools for biological studies. One of the primary biological activities that require volumetric imaging is blood dynamics. Blood is an essential component in the circulatory system, which transports nutrients, oxygen, and waste for the entire body. Anucleate blood cells, red blood cells (RBCs) and platelets, are majority contributors in homeostasis, the state of steady internal conditions, and hemostasis, the process of bleeding control. Any morphological anomalies of RBCs and platelets could result in mortality. For examples, poor deformability of RBCs influenced by blood-borne diseases (e.g. malaria, sickle) can result in poor delivery of nutrients and oxygen to major visceral organs. And excessive or insufficient blood coagulation due to kinds of platelet disorders can lead to thrombosis or abnormal bleeding. This thesis presents the development of volumetric imaging systems and tailored microfluidics platform for the study of diseased anucleate blood cells. Using a custom-built automated QPM system, quantitative deformability measurement of parasites infected RBCs was conducted using an adhesion assay. Furthermore, real-time QPM imaging of platelets aggregation was achieved for studying thrombus dynamic. Then, a hybrid image system, Holographic inverted Single Plane Illumination Microscopy (H+iSPIM), was developed to retrieve both structural and molecular information, providing multidimensional images at the same time. The first chapter introduces the aims and the structure of the thesis. The second, third and fourth chapters presents background of the techniques used in the thesis; volumetric microscopy techniques, biomechanics of anucleate blood cells, and microfluidic respectively. Chapter five elaborates the hardware and software development for an automated DHM system. This chapter is meant to extend the usage of DHM by automated image processing and data analysis. The next following two chapters (six and seven) describe the deformability studies of infected RBC and dynamics of platelet-platelet aggregate. Chapter eight proposes a hybrid imaging system, H+iSPIM, for multidimensional studies of cells in microfluidic systems. Conclusions, future works, and limitations of the developed system are discussed in the final chapter. In summary, this thesis presents the pursuit of versatile imaging systems for non-invasive imaging quantification of dynamic cellular studies using microfluidic devices for blood-related diseases.

description: We report the detection of a planetary companion around HIP 13044, a metal-poor star on the red Horizontal Branch. The detection is based on radial velocity observations with FEROS, a high-resolution spectrograph at the 2.2-m MPG/ESO telescope, located at ESO La Silla observatory in Chile. The periodic radial velocity variation of P = 16.2 days can be distinguished from the periods of the stellar activity indicators. We computed a minimum planetary mass of 1.25 MJup and an orbital semi-major axis of 0.116 AU for the planet. This discovery is unique in three aspects: First, it is the first planet detection around a star with a metallicity much lower than few percent of the solar value; second, the planet host star resides in a stellar evolutionary stage that is still unexplored in the exoplanet surveys; third, the star HIP 13044 belongs to one of the most significant stellar halo streams in the solar neighborhood, implying an extragalactic origin of the planetary system HIP 13044 in a disrupted former satellite of the Milky Way.

description: With the early afterglow localizations of gamma-ray burst positions made by Swift, the clear delimitation of the prompt phase and the afterglow is not so obvious any more. It is important to see weather the two phases have the same origin or they stem from different parts of the progenitor system. We will combine the two kinds of gamma-ray burst data from the Swift-XRT instrument (windowed timing and photon counting modes) and from BAT. A thorough desription of the applied procedure is given. We apply various binning techniques to the different data: Bayes blocks, exponential binning and signal-to-noise type of binning. We present a handful of flux curves and some possible applications.

description: The dynamic behaviour of compressed CH3F and CF3H has been studied between 150 and 400 K and to pressures of 200 MPa by measuring the spin-lattice relaxation times (T1) of the proton and fluor nuclei. Also the deuteron T1 of CD3F and CF3D were obtained in the whole p, T range. Both substances reveal a significant non-Arrhenian behaviour when the whole temperature range is studied. In addition the self-diffusion coefficients of these compounds and of their analogues CH3Cl, CH2Cl2 and CHCl3 have been investigated. The data obtained can be described best by the rough hard sphere model. It is found, that the rough hard sphere diameter (dRHS) of all compounds is almost independent of temperature (CF3H dRHS=0.39nm, CH3F dRHS=0.35nm, CH3Cl: 0.40nm, CH2Cl2: 0.44nm, CHCl3; 0.48 nm).

A periodical for a science : Xinli and psychological knowledge in Republican China 1922-1927
Creators: name: Yu, Jia
Publisher: name: University of British Columbia
Year: 2017

description: In the summer of 1921, a specialized periodical devoted to a new scientific discipline, modern psychology, was established synchronously with the founding of the Chinese Psychological Society in Nanjing. In the following six years, this serial scientific periodical, Xinli (心理), was engaged in promoting the professionalization of the psychologist community in Republican China, and constructing the earliest communications of psychological knowledge with Chinese laymen readers. This thesis underscores the historical agency of Xinli in shaping the growing field of modern psychology and in interweaving psychological knowledge with Chinese society during the early years of Republican China. By analyzing three aspects of Xinli, including its social and intellectual management, three psychologists’ elaborations on psychology testing, and one of Xinli’s columns that involved intensive participation of laymen readers, I argue that, in the case study of Xinli, the supposed gap between scientists and the public did not actually appear in the 1920s Republican China. This case study exemplifies that the professionalization of Chinese psychological scientists was mutually progressing with the popularization of the field; both took place mainly through the circulation of a scientific periodical, Xinli.

description: In our Spitzer 24 μm survey of hot white dwarfs (WDs) and archival Spitzer study of pre-WDs, i.e., central stars of planetary nebulae (CSPNs), we found mid-IR excesses for -15 WDs/pre-WDs. These mid-IR excesses are indicative of the presence of circumstellar dust that could be produced by sub-planetary objects. To further assess the nature of these IR-excesses, we have obtained Spitzer IRS, Gemini NIRI and Michelle, and KPNO 4m echelle spectra of these objects. In this paper we present the analysis of these spectroscopic observations and discuss the nature of these IR excesses.

The self-diffusion coefficients of CHF3 are determined between 142 K and 250 K. The activation energies derived from the data are [EaD]p = const = (6·1 ± 0·4) kJ mol-1, [EaD]V = const = (3·5 ± 0·4) kJ mol-1. Except for the lowest temperatures, compressed CHF3 appears to behave as a normal, rough hard-sphere fluid.

description: Nuclear magnetic relaxation time measurements are well suited to monitor orientational and positional fluctuations of water molecules in solutions. Hence the dependence of deuteron spin-lattice relaxation rates on pressure (pless-than-or-equals, slant225 MPa), temperature (180less-than-or-equals, slantTless-than-or-equals, slant283 K) and composition (NaCl: cless-than-or-equals, slant5 m, NaI: cless-than-or-equals, slant9.5 m) are reported in undercooled NaCl/D2O and NaI/D2O solutions over wide ranges of the external variables. The anomalous increase of molecular mobility upon compression, observed in neat undercooled water becomes less pronounced with increasing salt concentration until the pressure dependence reverts to normal behaviour at the edge of the glass forming composition range. This behaviour is qualitatively different from the recently studied systems LiCl- and MgCl2-D2O. In the presence of network breaking agents like hydrostatic pressure and/or ionic solutes molecular motions can be slowed down upon cooling sufficiently for the relaxation rates to exhibit a maximum and to become frequency dependent. Within a recently developed motional model a detailed account of orientational fluctuations of water molecules can be given and conclusions are drawn regarding the influence of structure and composition on molecular motions.

description: We calculate the magnetization torque due to the spin polarization of the itinerant electrons by deriving the kinetic spin Bloch equations based on the $s$-$d$ model. We find that the first-order gradient of the magnetization inhomogeneity gives rise to the current-induced torques, which are consistent to the previous works. At the second-order gradient, we find an effective magnetic field perpendicular to the spin stiffness filed. This field is proportional to the nonadiabatic parameter $β$. We show that this vertical spin stiffness term can significantly modify the domain-wall structure in ferromagnetic semiconductors and hence should be included in the Landau-Lifshitz-Gilbert equation in studying the magnetization dynamics.

title: The effect of comparison on the perceived similarity of complex visual stimuli
Creators: name: Engelbrecht, Paula Christiane
Publisher: name: Goldsmiths, University of London
Year: 2018

description: Comparison has been shown to decrease the perceived similarity of artificial face stimuli that are difficult to discriminate (Mundy, Honey, & Dwyer, 2007). This thesis presents seven experiments that examined the effect of comparison on the perceived similarity of a wider range of unfamiliar face stimuli. Participants were asked to compare two faces before either rating their perceived similarity, or deciding whether they are the same person. In the first five experiments participants were shown face pairs that ranged in phenotypic similarity—the degree to which the two faces look alike. With the exception of highly similar face morphs comparison was found to increase the perceived similarity of both phenotypically similar and dissimilar face pairs, relative to a no-comparison control. This finding suggests that for most naturally occurring face stimuli, comparison results in an increase in perceived similarity. In the last two experiments the quality of one of the stimuli in each pair was degraded to simulate the effects of poor quality video footage. A comparison-related decrease in perceived similarity was found in both experiments. This finding suggests that pictorial differences between face stimuli—including differences in image quality, camera distance and lighting, variations in pose and facial expression, and the presence of disguises such as hats and sunglasses—play an important role in mediating the effect of comparison on perceived similarity.

description: Measurements of the self-diffusion coefficient in supercooled water to 300 MPa are reported. Translational diffusion in liquid water at 243 K is enhanced by 60% when the pressure is increased from 0.1 to 150 MPa, and rotational diffusion is enhanced by almost 250% between 0.1 and 250 MPa. These striking anomalies are interpreted in terms of the proximity of a conjectured line of spinodallike stability limits in the supercooled liquid.

description: Brown dwarf companions to white dwarfs are rare, but recent infra-red surveys are slowly reveal- ing examples. We present new observations of the post-common envelope binary WD0137-349, which reveals the effects of irradiation on the ~ 0.05M* secondary, and new observations of GD 1400 which show that it too is a close, post-comon envelope system. We also present the lat- est results in a near-infrared photometric search for unresolved ultracool companions and to white dwarfs with UKIDSS. Twenty five DA white dwarfs were identified as having photometric excesses indicative of a low mass companion, with 8-10 of these having a predicted mass in the range asso- ciated with brown dwarfs. The results of this survey show that the unresolved (< 2") brown dwarf companion fraction to DA white dwarfs is 0.3 \leq fWD+BD \leq 1.3%.

description: Spin‐lattice (T1) and spin–spin (T2) relaxation times of the deuterons in supercooled D2O at 225 MPa, measured at two frequencies: 55.54 and 39.14 MHz down to 188 K are reported. The results show that T1 and T2 become frequency dependent in supercooled liquid water under high hydrostatic pressure at temperatures below ∼220 K. Theoretical expressions for the relaxation rates are deduced under the assumption that the orientational fluctuations of the water molecules are composed of fast librational oscillations and slower diffusional motions. The effect of the librations is to reduce the size of the deuterium quadrupole coupling constant. The diffusional motions are nearly isotropic and dominate the T dependence of the relaxation times. The autocorrelation function of the slow orientational fluctuations was assumed to be exponential at long times with a single time constant, the orientational correlation time τ2. The T dependence of the latter is well described by the VTF equation. The parameters obtained by least squares fitting the experimental spin‐lattice relaxation times to an isotropic motional model correctly predict the temperature and frequency dependence of the spin–spin relaxation times.
Free‐electron laser study of the nonlinear magnetophotoconductivity in n‐GaAs

description: The University of California at Santa Barbara free‐electron laser was used to investigate the kinetics of electrons bound to shallow donors in n‐GaAs by saturation spectroscopy. The resonant photothermal conductivity arising from 1s–2p+ shallow donor excitations in a magnetic field was measured at intensities greatly exceeding that of earlier investigations and saturation of bound‐to‐free photoionization transitions was achieved. The impurity resonance photoconductive signal shows a distinct intensity dependence caused by competing bound‐to‐free transitions which saturate differently. This permits a more detailed evaluation of the electron recombination kinetics than was previously possible, yielding the ionization probability of the 2p+ state, the transition time of electrons from the 2p+ level to the gound state, and the recombination time of free carriers.
An examination of influences on prescription drug use amongst older adults with and without chronic illness in two Canadian provinces
Creators: name: Chan, Fiona Ka Ieng
Publisher: name: University of British Columbia
Year: 2018

description: Background - Prescription medications, which are a critical component of modern medicine, are not covered under the Canada Health Act. Canadian prescriptions are financed through a combination of public financing, private insurance, and out-of-pocket payments. This leaves potential coverage gaps amongst different segments of the population. There are current discussions of a national pharmacare strategy to address this issue. It remains unclear how such a policy, particularly for seniors, should be financed. Methods – We first studied British Columbia’s publicly-funded pharmacare program to examine the impact of income-based deductibles on older adults with chronic obstructive pulmonary disease (COPD) in regards to prescription drug utilization and other health services. This was analyzed utilizing a regression discontinuity design with administrative datasets. The second study used logistic regression to examine the trend in employer-sponsored health insurance (EHI) availability amongst Ontario’s retirees from 2005 to 2014 using data from the Canadian Community Health Survey. Results - Deductibles had no effect on prescription utilization amongst a cohort of older adults living with COPD in BC. However, over 40% of the eligible person-years analyzed did not obtain a prescription for COPD treatment, suggesting severe under-treatment in this population. Results also suggest an increased use of inhaled corticosteroids, which may be due to a special authority process and may not be appropriate for COPD. A decline in EHI availability was apparent for Ontario’s retirees between 2005 and 2013-2014. EHI availability is strongly linked to household income, with those of a lower income-decile having the lowest odds of having EHI. Conclusion - Imposing a modest income-based deductible was not found to impact prescription utilization or utilization of other health services, even amongst a population with a chronic condition facing comparatively high prescription costs. In contrast, supplemental help in making prescriptions more affordable for the older adult population may be diminishing. A small but statistically significant decrease was observed in EHI – the main source of aid in prescription affordability apart from the public system. These results suggest that a comprehensive strategy to address medication adherence is warranted to minimize future health system burden.

A two-step fusion process for multi-criteria decision applied to natural hazards in mountains

Year: 2010

description: Mountain river torrents and snow avalanches generate human and material damages with dramatic consequences. Knowledge about natural phenomenona is often lacking and expertise is required for decision and risk management purposes using multi-disciplinary quantitative or qualitative approaches. Expertise is considered as a decision process based on imperfect information coming from more or less reliable and conflicting sources. A methodology mixing the Analytic Hierarchy Process (AHP), a multi-criteria aid-decision method, and information fusion using Belief Function Theory is described. Fuzzy Sets and Possibilities theories allow to transform quantitative and qualitative criteria into a common frame of discernment for decision in Dempster-Shafer Theory (DST ) and Dezert-Smarandache Theory (DSmT) contexts. Main issues consist in basic belief assignments elicitation, conflict identification and management, fusion rule choices, results validation but also in specific needs to make a difference between importance and reliability and uncertainty in the fusion process.

Metastable shallow donor states of n-GaAs in a magnetic field
Creators: name: Wagner, H. P.
name: Prettl, Wilhelm
Publisher: name: Universität Regensburg
Year: 1988
Subjects: subject: 530 Physik

description: The photothermal spectrum of shallow donors in n-GaAs has been investigated at various magnetic field strengths up to 4T at different temperatures between 1.4 and 12K. Weak spectral structures observed at frequencies above the dominant 1s → 2p +1 line are attributed to optical excitations into metastable states which arise in a magnetic field. The final states of these transitions can be unambigously assigned by using high field quantum numbers.

The targum (1878:May)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1878

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: The photothermal spectrum of shallow acceptors in p-Ge has been investigated at various magnetic field strengths up to 5.6 T at a temperature of 7.5 K by FIR-Fourier-spectroscopy. From the observed Zeeman splittings of the excited states of the boron acceptor the coefficients of the linear and quadratic field dependence have been evaluated andg-factors of theD-,C- and theG-transitions have been determined based on a standard group theoretical approach.
Z'_{B-L} discovery potential at the LHC for \sqrt{s}=7 TeV

description: We present the Large Hadron Collider (LHC) discovery potential in the Z' sector of a U(1)_{B-L} enlarged Standard Model also encompassing three heavy Majorana neutrinos, for \sqrt{s}=7 centre-of-mass energy, considering both the Z'_{B-L}\rightarrow e^+e^- and Z'_{B-L}\rightarrow μ^+μ^- decay channels. Electrons provide a higher sensitivity to smaller couplings at small Z'_{B-L} boson masses than do muons. The run of the LHC at \sqrt{s}=7 TeV, assuming at most \int \mathcal{L} \sim 1 fb^{-1}, will be able to give similar results to those that will be available soon at the Tevatron in the lower mass region, and to extend them for a heavier M_{Z'}. A 5σdiscovery could be possible up to M_{Z'}=1.2(0.9) TeV at the LHC(Tevatron), while a 2σexclusion at the LHC could be possible up to M_{Z'}=1.6 TeV. The new gauge coupling g'_1 can been probed, at 5σ, down to \sim (3 ÷4) \cdot 10^{-2} with electrons and down to \sim (4 ÷5) \cdot 10^{-2} with muons, both at the LHC and at the Tevatron, for M_{Z'}=600 GeV. The Z' boson in this model exhibits novel signatures at the LHC, as multi-lepton and multi-jet decays via heavy neutrinos, that allow one to measure the heavy neutrino masses involved. Lastly, the simultaneous measurement of both the heavy neutrino mass and decay length (over a large region of parameter space, the heavy neutrinos are rather long-lived particles) enables an estimate of the absolute mass of the parent light neutrino.

description: The photoconductance of polycrystalline silicon films at photon energies smaller than the band gap has been measured as a function of intensity applying a 1.3 μm wavelength semiconductor laser. The observed photosignal increases superlinearly at low intensities and saturates above about 1.5 W/cm−2. This distinct nonlinearity is caused by a significant energy dependence of optical to thermal cross sections of trap states in the band gap. Assuming a three‐level‐rate equation model, grain boundary trap densities were evaluated.
