FIR photoconductivity at filamentary current flow in n-GaAs in a magnetic field
Creators: name: Golubev, V. G.

Publisher: name: Universität Regensburg
Year: 1991
Subjects: subject: 530 Physik

description: A large number of spectral structures are observed by far infrared magneto-photo-conductivity in n-GaAs at 4.2K biased above impurity breakdown in a regime where current flow is filamentary. Phase changes are found in the center of the 1s−2p+1 line and new structures are observed which shift to higher magnetic fields with increasing bias voltage. The large strength and the intensity dependence of the photosignals indicate that the observed phenomena are due to self-organizing effects of the filament. Small variations of the electron population by infrared irradiation may cause substantial rearrangements of the spatial current distribution.

Publisher: name: Universität Regensburg
Year: 1991
Subjects: subject: 530 Physik

description: The optical saturation of nonresonant photoionization of shallow acceptors in p-Ge was investigated at low temperatures using a high-power FIR molecular laser. The experimental results were analyzed in terms of a rate equation model. Very small saturation intensities in the order of 10 mW/cm−2 and long free hole recombination times in the range of 10 μs were observed.

description: The steady‐state photoconductance and the transient photoresponse of boron‐doped polycrystalline silicon films have been measured as a function of intensity at photon energies above and below the band gap applying several semiconductor lasers. The intensity dependence of the dc photosignal and the transient behavior are distinctly different for interband and subgap excitation. A kinetic model taking into account grain boundary as well as bulk carrier generation and recombination has been developed describing the observed nonlinear and transient effects consistently. The experimental results yield the density of occupied and unoccupied trap states, absolute values for the optical absorption cross section and thermal capture cross sections and relaxation time constants.

description: The far-infrared magneto-photoconductivity due to optical transitions from the acceptor ground state into quasi-bound Coulomb states in p-Ge has been investigated at low temperatures as a function of intensity applying a high-power cw molecular laser. For intensities above about 1 mW/cm2 the photoconductive signal shows a square root dependence on intensity, which is attributed to nonlinear free carrier capture in the low compensated material. The experimental results are analyzed in terms of a rate equation model yielding the kinetic parameters of the carrier generation- and recombination process involved.

description: A Nernst effect has been observed in a high temperature superconductor for the first time. Irradiating superconducting Tl–Ba–Ca–Cu–O thin films by short pulses of a TEA-CO2 laser, a photovoltaic signal is detected perpendicular to a magnetic field applied parallel to the film surface. The signal is attributed to magnetic flux line depinning and flux line transport driven by the laser induced temperature gradient. The results are described by thermal flux line activation leading to a calculated distribution of pinning energies from 100 K to 4000 K.

Exercise-induced bronchoconstriction – the effect of inhaled ß₂-agonists on athletic performance in humans
Creators: name: Koch, Sarah
Publisher: name: University of British Columbia
Year: 2017

description: The purpose of this thesis was to investigate the ergogenic potential of inhaled ß₂-agonists (IBAs) in athletes with and without exercise-induced bronchoconstriction (EIB) from multiple angles: by assessing the effect of 400 µg of salbutamol, a commonly used IBA, in female athletes (Chapter 2); and by analyzing athletic performance after the inhalation of the maximal daily dose of salbutamol, i.e. 1600 µg, by taking dose per kg of body mass into consideration (Chapter 3). Furthermore, four methods to calculate the fall index (FI) in the eucapnic voluntary hyperpnea (EVH) challenge were evaluated (Chapter 4). Female (Chapter 2) and male (Chapter 3) cyclists were screened for EIB using the EVH challenge. On two subsequent visits, athletes performed one 10-km time trial per visit. In a randomized order, athletes inhaled either salbutamol or placebo before completing the time trials. Athletic performance was assessed using mean power output. In Chapter 4, the FI of the EVH challenges from Chapters 2 and 3 were calculated using four methods and compared to the pulmonary response to the placebo time trial. Additionally, the intensity of the EVH target ventilation, calculated as 30 x forced expiratory volume in 1 second (FEV1), was evaluated by comparing it to the highest generated ventilations in a graded maximal exercise test (GXT). Despite significant increases in FEV1 after IBA use, athletic performance was not improved in female (Chapter 2) or male (Chapter 3) athletes, regardless of EVH status. In women, power output was decreased, despite a significant increase in oxygen consumption, suggestive of an increased stimulation of women’s adrenergic ß₂-system. Similarly, in male athletes, significant increases in heart rate, ventilation, and leg discomfort could indicate an upregulation of the adrenergic nervous system, independent of relative IBA dose. Lastly, there were significant differences between the four FI calculations (Chapter 4), influencing the EVH interpretations. Normalizing FIs by the ventilations achieved during voluntary hyperpnea was not supported in athletes with high percent predicted values for FEV1 due to an increased risk of false-positives. The intensity of the EVH target ventilation ranged between 67% - 135% when normalized to the GXT ventilations.

description: The fragmentation of neutron-rich 132Sn nuclei produced in the fission of 238U projectiles at 950 MeV/u has been investigated at the FRagment Separator (FRS) at GSI. This work represents the first investigation of fragmentation of medium-mass radioactive projectiles with a large neutron excess. The measured production cross sections of the residual nuclei are relevant for the possible use of a two-stage reaction scheme (fission+fragmentation) for the production of extremely neutron-rich medium-mass nuclei in future rare-ion-beam facilities. Moreover, the new data will provide a better understanding of the "memory" effect in fragmentation reactions.

description: The "ALFA Ultra Deep Survey" (AUDS) is an ongoing 21-cm spectral survey with the Arecibo 305m telescope. AUDS will be the most sensitive blind survey undertaken with Arecibo's 300 MHz Mock spectrometer. The survey searches for 21-cm HI line emission at redshifts between 0 and 0.16. The main goals of the survey are to investigate the HI content and probe the evolution of HI gas within that redshift region. In this paper, we report on a set of precursor observations with a total integration time of 53 hours. The survey detected a total of eighteen 21-cm emission lines at redshifts between 0.07 and 0.15 in a region centered around ra~0:00h, dec= 15:42deg. The rate of detection is consistent with the one expected from the local HI mass function. The derived relative HI density at the median redshift of the survey is rho_HI[z=0.125]=(1.0+/-0.3)*rho_0, where rho_0 is the HI density at zero redshift.

description: The dependence of the long-term optical/UV variability on the spectral and the fundamental physical parameters for radio-quiet active galactic nuclei (AGNs) is investigated. The multi-epoch repeated photometric scanning data in the Stripe-82 region of the Sloan Digital Sky Survey (SDSS) are exploited for two comparative AGN samples (mostly quasars) selected therein, a broad-line Seyfert\,1 (BLS1) type sample and a narrow-line Seyfert\,1 (NLS1) type AGN sample within redshifts 0.3--0.8. Their spectral parameters are derived from the SDSS spectroscopic data. It is found that on rest-frame timescales of several years the NLS1-type AGNs show systematically smaller variability compared to the BLS1-type. In fact, the variability amplitude is found to correlate, though only moderately, with the Eigenvector\,1 parameters, i.e., the smaller the \hb\ linewidth, the weaker the [O\,III] and the stronger the \feii\ emission, the smaller the variability amplitude is. Moreover, an interesting inverse correlation is found between the variability and the Eddington ratio, which is perhaps more fundamental. The previously known dependence of the variability on luminosity is not significant, and that on black hole mass---as claimed in recent papers and also present in our data---fades out when controlling for the Eddington ratio in the correlation analysis, though these may be partly due to the limited ranges of luminosity and black hole mass of our samples. Our result strongly supports that an accretion disk is likely to play a major role in producing the opitcal/UV variability.

description: The origin of subdwarf B (sdB) stars is not fully understood yet since it requires high mass loss at the red giant stage. SdBs in close binary systems are formed via common envelope ejection, but the origin of apparently single sdB stars remains unclear. Substellar companions may be able to trigger common envelope ejection and help forming sdBs that appear to be single. Using a sample of high resolution spectra we aim at detecting small radial velocity (RV) shifts caused by such low mass (sub-)stellar companions. The RVs are measured with high accuracy using sharp metal lines. Our goal is to test the theoretical predictions and put constraints on the population of the lowest mass companions to sdB stars.

description: The exact non-Markovian dynamics of a microcavity strongly coupled to a general reservoir at arbitrary temperature is studied. With the exact master equation for the reduced density operator of the cavity system, we analytically solve the time evolution of the cavity state and the associated physical observables. We show that the non-Markovian dynamics is completely determined by the propagating (retarded) and correlation Green functions. Compare the non-Markovian behavior at finite temperature with those at zero-temperature limit or Born-Markov limit, we find that the non-Markovian memory effect can dramatically change the coherent and thermal dynamics of the cavity. We also numerically study the dissipation dynamics of the cavity through the mean mode amplitude decay and the average photon number decay in the microwave regime. It is shown that the strong coupling between the cavity and the reservoir results in a long-time dissipationless evolution to the cavity field amplitude, and its noise dynamics undergoes a critical transition from the weak to strong coupling due to the non-Markovian memory effect.

description: Experimental investigations of the Hall effect at the occurrence of autonomous current fluctuations in high-purity n-GaAs epitaxial layers at low temperatures show that the transition to chaos is accompanied by intermittent collapses in the Hall voltage. This may represent the significant third mechanism for a transition into chaos according to the Ruelle-Takens-Newhouse scenario. Basically, space charges accumulated in the filament boundaries yield different impact ionization probabilities at opposite sides of the filament destabilizing the current flow and causing multimodal oscillation phenomena originating at the filament borders.

description: Experiments are reported which show that temperature gradients perpendicular to the surface of epitaxial normal conducting YBa2Cu3O7−δ films give rise to large transversal voltages between contacts on the film surface. The temperature gradients have been produced by pulsed laser irradiation and by continuous heating of the films by heater wires. To explain the large lateral voltages, an atomic layer thermopile is proposed, which may be formed by the layered structure of the material.

description: The resistance response of polycrystalline Tl2Ba2CaCu2O8 films to short laser pulses has been investigated for a wide range of far-infrared frequencies. For temperatures T ll Tc a drastic change in response time is observed at a critical frequency νc simeq 4 THz. The time constant increases from about 1 ns at ν < νc to 1 μs at ν > νc. The critical frequency is attributed to a superconducting energy gap with 2Δ(0)/kB Tc simeq 2.

description: The location of fluctuations occurring in a filamentary current flow is detected by spatially resolved photocurrent measurements using optical interband excitation in n-GaAs at low temperatures. Current fluctuations are only observed in the filament boundaries. In the presence of an external magnetic field, characteristics like the frequency and amplitude of the spontaneous current oscillations are different for opposite edges of the filament pattern. The observed phenomena are discussed in terms of electron generation-recombination kinetics.

The effect of an education seminar on support persons of individuals with cancer on knowledge and decision making related to complementary and alternative medicine
Creators: name: Allen Searson, Nancy
Publisher: name: University of British Columbia
Year: 2017

description: Complementary and alternative medicine (CAM) use is prevalent among cancer patients; thus, patients require information about the efficacy and safety of these therapies. Some cancer patients struggle to make informed decisions, highlighting the need for education and decisional support. Patients often look to support persons for assistance in treatment decision making; recognizing the social context of decision making, a patient education seminar focused on CAM therapies was developed to include support persons. This study examines the effect of an education seminar for adult cancer patients and their support persons on support persons’ use of CAM, knowledge about CAM and CAM decision making, CAM information-seeking behaviour, and decision-making experience pertaining to CAM. This research idea was developed following a number of projects completed as part of the Complementary Medicine Education and Outcomes (CAMEO) research program. The data presented for the first time in this thesis were collected from support persons as part of an initial study of the CAMEO research program. Surveys completed before and after the education seminar were used to examine the impact of the education seminar on support persons. Six measurement scales comprised the baseline and follow-up surveys: a CAM use survey, a CAM knowledge scale, two decisional outcomes scales (i.e., decision self-efficacy and decision conflict), a distress scale, and a demographic form. The conceptual frameworks providing the foundation for the CAMEO program, as well as data collection and analysis, were the Shared Decision Making and Ottawa Decision Support Framework. The Supportive Care Framework informed how decision support interventions were developed and offered by the CAMEO program, including the patient and support person education intervention. ii There was no significant difference in support persons’ CAM use following the seminar. After the seminar, most people continued to find information about CAM using the Internet; however, there was a significant increase in the use of the CAMEO website. In addition, significant increases in support persons’ CAM knowledge were observed, as well as improved confidence in four key areas of CAM decision making. A significant decrease in support persons’ decisional conflict was also found. No significant changes in decision- making distress were found.

The effect of a low-carbohydrate high-fat breakfast on glycemic control in type 2 diabetes
Creators: name: Chang, Courtney Rochelle
Publisher: name: University of British Columbia
Year: 2018

description: Improving overall glycemia by targeting postprandial glucose spikes, particularly at the breakfast meal when insulin resistance is the highest in type 2 diabetes (T2D), may help to prevent diabetes complications. The purpose of this thesis was to determine whether consuming a low- carbohydrate high-fat breakfast was superior to a breakfast with the dietary guidelines recommended nutrient profile for improving postprandial and 24-hour blood glucose responses to mixed meals in individuals with T2D. Adults with physician diagnosed T2D (N=23, 59 ± 11y, A1c: 6.7 ± 0.6%, BMI: 31 ± 7kg/m2) completed two 24-h isocaloric intervention periods, in a random order. Participants consumed either i) a low-carbohydrate high-fat breakfast [LC-BF; <10% energy from carbohydrate (CHO), 85% energy from fat (FAT), and 15% energy from protein (PRO)], or ii) a breakfast with the dietary guidelines recommended nutrient profile (GL- BF; 55%CHO/30%FAT/15%PRO), with the same lunch and dinner provided (both 55%CHO/30%FAT/15%PRO). Continuous glucose monitoring assessed postprandial glucose responses to each meal (incremental area under the curve; iAUC) and the mean 24-h glucose during each intervention. The postprandial glucose excursion (3h iAUC) after the LC-BF was ~80% lower than the GL-BF (p<0.01). Overall postprandial hyperglycemia (measured as the sum of the 3h iAUC of breakfast, lunch and dinner), and glycemic variability (mean amplitude of glycemic excursions [MAGE]) were significantly reduced with the LC-BF compared to the GL- BF (3h iAUC: -100 ± 116 mmol/L•9h, p<0.01; MAGE: -0.4 ± 0.8 mmol/L•24h, p=0.03). However, the mean 24-h blood glucose was not significantly reduced (LC-BF: 7.2 ± 1.1 mmol/L vs. GL-BF: 7.5 ± 1.5 mmol/L, p=0.09). Restricting carbohydrate at breakfast reduces postprandial hyperglycemia in individuals with T2D. A low-carbohydrate high-fat breakfast may be a simple and effective strategy to reduce the development of diabetes complications in T2D and long-term interventions are warranted.

description: The response of a polycrystalline thin‐film Bi2Sr2CaCu2O8 superconducting stripe to short‐pulse far‐infrared (λ=447 μm) radiation is reported. Under constant current bias, a photosignal is generated when the maximum zero voltage current is exceeded. Measurements of the sensitivity as a function of temperature, bias current, and intensity reveal the signal source to be nonbolometric. The response is found to obey a (power)1/2 law over more than 2 orders of magnitude. We believe the detection mechanism arises from the interaction of grain boundary Josephson junctions with radiation induced screening currents.

description: The experimental data of the COSY-GEM Collaboration for the recoil-free transfer reaction p (27Al, 3He) π- p' X, leading to the formation of bound state of eta (η) meson in 25Mg nucleus, is reanalyzed in this paper. In particular, predicted values of binding energy and half-width of the η-mesic nucleus 25Mgη, given by different theoretical approaches, are compared with the ones obtained from the experimental missing mass spectrum. It is found that the spectrum can be explained reasonably well if interference effect of another process, where ηis not bound in 25Mg but is scattered by the nucleus and emerge as a pion, is taken into account. The data also indicate that the interaction between N*(1535) and a nucleus is attractive in nature.

Our initial results reproduce past findings. According to our study the mass-loss during the red giant branch does not significantly affect the semi major axis of the planet and for a 1.5 M star the capture radius is approximately 300 R or 1.4 AU.

description: A method of making high-pass waveguide filters for the far infrared is described. The filters are formed from arrays of tightly packed narrow-bore metal tubes. Such filters feature sharp cut-off transitions in the region between 20 cm-1 and 40 cm-1. Transmission above cut-off is comparable to that in similar filters produced by drilling holes in thin metal sheets. Typically the transmissions just above cut-off are about 5% while that just below was measured as less than 0.1%.

description: Our goal is to investigate the X-ray timing and spectral variability of the high-mass X-ray binary 1A 1118-615 during a type-II outburst. We performed a detailed color, spectral and timing analysis of a giant outburst from 1A 1118-615, using RXTE data. Results. We report the discovery of a variable quasi-periodic oscillation (QPO) in the power spectral density of 1A 1118-615, with a centroid frequency of ~0.08 Hz. The centroid frequency of the QPO correlates with the X-ray flux, as expected according to the most accredited models for QPO production. For energies above ~4 keV, the QPO rms variability decreases as the energy increases. Pulse profiles display energy dependence, with a two-peak profile at lower energies, and a single peak at higher energies. From spectral analysis, we confirm the presence of a cyclotron absorption feature at ~60 keV, the highest value measured for an X-ray pulsar. We find that the spectral parameters (photon index, cutoff energy, iron fluorescence line strength) display a marked dependence with flux. We detect two different levels of neutral hydrogen column density, possibly due to the Be companion activity. We report for the first time a correlation between the timing and spectral parameters in an X-ray pulsar. All the correlations found between spectral/timing parameters and X-ray flux are present up to a flux of ~6x10^-9 erg cm^-2 s^-1, when a saturation level is reached. We propose that the saturation observed corresponds to the minimum extent of the neutron star magnetosphere. We estimate the magnetic field of the neutron star from two independent ways, using results from spectral (cyclotron line energy) and timing (QPO frequency) analysis, obtaining consistent values, of ~7-8x10^12 G. Results from the comprehensive spectral and timing analysis are discussed in comparison with other X-ray pulsars.

description: Computer-aided surgery intensively uses the concept of navigation: after having collected CT data from a patient and transferred them to the operating room coordinate system, the surgical instrument (a puncture needle for instance) is localized and its position is visualized with respect to the patient organs which are not directly visible. This approach is very similar to the GPS paradigm. Traditionally, three orthogonal slices in the patient data are presented on a distant screen. Sometimes a 3D representation is also added. In this study we evaluated the potential of adding a smart phone as a man-machine interaction device. Different experiments involving operators puncturing a phantom are reported in this paper.

Chiral nematic mesoporous organosilica materials templated with cellulose nanocrystals
Creators: name: Terpstra, Andrea Susanne
Publisher: name: University of British Columbia
Year: 2019

description: The synthesis and characterization of new mesoporous organosilica materials with twisted porous networks and defined nanostructures was explored. Spindle-shaped cellulose nanocrystals (CNCs) with nanoscale dimensions can be isolated through the acid-catalyzed hydrolysis of wood pulp. These CNCs behave as chiral nematic lyotropic liquid crystals and are advantageous for the soft-templating of mesoporous materials as they can produce helically arranged pores. As such, CNCs show promise as inexpensive and renewable precursors for the development of nanomaterials. In this thesis, CNCs were used to template chiral nematic mesoporous organosilica (CNMO) materials through the co-condensation of bridged alkoxysilanes, R(Si(OR′)₃)₂, with aqueous CNC suspensions. Removal of the CNCs produced free-standing organosilica films that have interconnected pore structures and long-range chiral order imparted by the CNC template. Organic functionality was introduced as an integral component of the organosilica structure by varying the alkoxysilane precursors. The syntheses of alkylene-bridged (C₁-C₆), aromatic-bridged, ethenylene-bridged, and sulfur-containing CNMO films are reported. It was determined that phase separation between the alkoxysilanes and CNC suspension could be minimized by using mixed solvent systems of water and DMF during self-assembly. The new CNMO films display tunable photonic properties resulting from the repeating helical structure as well as thermal stabilities and pore connectivity that depend on the organic linker used. The combination of chirality and mesoporosity in these organosilica films suggests applications in hard templating, chiral catalysis, and sensing. CNMO films were investigated as support materials by functionalizing them with spiropyran molecules for sensing or manganese salphen complexes for catalysis. Spiropyran-bound CNMO films were used for photopatterning and behaved as reversible divalent metals sensors. Heterogeneous manganese salphen/CNMO films displayed similar catalytic conversion to the homogeneous catalyst, however, a small enantiomeric excess (5%) was observed suggesting that the chiral environment of the films may affect catalysis. Finally, metal ferrites [MFe₂O₄ (M = Ni, Cu, Zn, Co)] with chiral nematic nanostructures were prepared through hard templating with chiral nematic mesoporous silica. These materials beautifully replicated the three-dimensional structure of the CNCs liquid crystalline phase and their crystallinity and pore sizes were controlled by altering the calcination temperatures.

description: A novel nonlinear model is presented for the occurrence of current fluctuations at low temperatures in extrinsic semiconductors. It is based on impact ionization of shallow impurities and structure-forming processes leading to a current filament. Numerical investigations reproduce the current-voltage characteristics and reveal regular, quasiperiodic, and frequency-locked spontaneous current oscillations and a Ruelle-Takens-Newhouse transition to chaos in agreement with experimental observations in n-type GaAs.

description: We introduce an event-based corpuscular simulation model that reproduces the wave mechanical results of single-photon double slit and two-beam interference experiments and (of a one-to-one copy of an experimental realization) of a single-photon interference experiment with a Fresnel biprism. The simulation comprises models that capture the essential features of the apparatuses used in the experiment, including the single-photon detectors recording individual detector clicks. We demonstrate that incorporating in the detector model, simple and minimalistic processes mimicking the memory and threshold behavior of single-photon detectors is sufficient to produce multipath interference patterns. These multipath interference patterns are built up by individual particles taking one single path to the detector where they arrive one-by-one. The particles in our model are not corpuscular in the standard, classical physics sense in that they are information carriers that exchange information with the apparatuses of the experimental set-up. The interference pattern is the final, collective outcome of the information exchanges of many particles with these apparatuses. The interference patterns are produced without making reference to the solution of a wave equation and without introducing signalling or non-local interactions between the particles or between different detection points on the detector screen.

description: Photoproduction of ηmesons off light nuclei (d, 3He, 7Li) has been measured at the tagged photon beam of the Mainz MAMI accelerator with the combined Crystal Ball/TAPS detection system. Special attention was given to the threshold behavior of the reactions in view of possible indications for the formation of (quasi-) bound η-nucleus states, so-called η-mesic nuclei. A very strong threshold enhancement of coherent ηphotoproduction off 3He was found and coherent ηphotoproduction off 7Li was observed for the first time. Preliminary results will be discussed.

Connections between Tilted Accretion Disks around White Dwarfs and Substellar Companions

description: Accretion disks in white dwarf systems are believed to be tilted. In a recent publication, the lift force has been suggested to be a source to disk tilt, a source that is likely relevant to all accretion disk systems. Lift is generated by slightly different supersonic gas stream speeds flowing over and under the disk at the bright spot. In this conference proceeding, we focus on whether a brown dwarf donor star accreting onto a white dwarf primary has enough mass to contribute to disk tilt. We also would like to obtain whether a white dwarf - brown dwarf close binary system has enough mass to induce and maintain a disk tilt of four degrees. We adopt SDSS 103533.03+055158.4 as our model system which has a mass transfer rate of (10 \pm 2) x 10-12 M* yr-1. We find that the brown dwarf in SDSS 1035 does not have enough mass to contribute to disk tilt. We find a gross magnitude of the minimum mass transfer rate to be - 10-10 M* yr-1 . We conclude that SDSS 1035 does not seem to have a high enough mass transfer rate to induce and maintain an observable disk tilt. Hence one reason why brown dwarf donor systems may be so difficult to find could be due to their low mass transfer rates which do not induce observable dynamical effects that is typical in white dwarf-red dwarf CVs.
