Signal and noise characteristics of photovoltaic P-N junction diodes
Creators: name: Galbraith, Donald Stewart
Publisher: name: University of British Columbia
Year: 2012

description: The noise characteristics of ideal photovoltaic p-n junction diodes are discussed and investigated. The hypothesis is advanced that the open-circuit noise from an illuminated ideal diode is entirely due to the shot noise of the various current contributions. Theoretical justification for this theory is developed and the parameter t, the effective noise temperature ratio, is introduced. The possible reasons for excess noise in p-n photo-diodes observed in earlier experiments are suggested. The dc and ac behavior of a real diode chosen to be very nearly ideal in its dc characteristic is found to be consistent with existing diode theory. The various parameters appropriate to the device are evaluated. Equipment for noise measurement is selected and a comparison technique adopted. This method avoids many of the possible errors inherent in an absolute measurement and allows an equivalent noise resistance resolution of about 200 ohms at room temperature in the 200 cs bandwidth measured. The open-circuit noise of the selected diode is measured at 20 and 30 kc as a function of illumination and the results interpreted in terms of the equivalent resistance in thermal equilibrium which would give the same noise. Comparison of this set of values with the real part of the junction impedance in each case indicates that the theory advanced is adequate to predict noise under these circumstances. The signal-to-noise ratio for a photo-diode used as an open-circuit radiation detector is developed, and several recommendations are made regarding the design of a photo-diode to display the most favourable signal-to-noise ratio under illumination.

Non-DMS related ferromagnetism in transition metal doped zinc oxide
Creators: name: Potzger, Kay

Year: 2009
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: We review pitfalls in recent efforts to make a conventional semiconductor, namely ZnO, ferromagnetic by means of doping with transition metal ions. Since the solubility of those elements is rather low, formation of secondary phases and the creation of defects upon low temperature processing can lead to unwanted magnetic effects. Among others, ion implantation is a method of doping, which is highly suited for the investigation of those effects. By focussing mainly on Fe, Co or Ni implanted ZnO single crystals we show that there are manifold sources for ferromagnetism in this material which can easily be confused with the formation of a ferromagnetic diluted magnetic semiconductor (DMS). We will focus on metallic as well as oxide precipitates and the difficulties of their identification.

description: We discuss nonlocal symmetries and nonlocal conservation laws that follow from the systematic potentialisation of evolution equations. Those are the Lie point symmetries of the auxiliary systems, also known as potential symmetries. We define higher-degree potential symmetries which then lead to nonlocal conservation laws and nonlocal transformations for the equations. We demonstrate our approach by the Burgers' hierarchy and the Calogero-Degasperis-Ibragimov-Shabat hierarchy.

description: The superfluid transition of a three-dimensional gas of hard-sphere bosons in a disordered medium is studied using quantum Monte Carlo methods. Simulations are performed in continuous space both in the canonical and in the grand-canonical ensemble. At fixed density we calculate the shift of the transition temperature as a function of the disorder strength, while at fixed temperature we determine both the critical chemical potential and the critical density separating normal and superfluid phases. In the regime of strong disorder the normal phase extends up to large values of the degeneracy parameter and the critical chemical potential exhibits a linear dependence in the intensity of the random potential. The role of interactions and disorder correlations is also discussed.

description: Background: Connectivity mapping is a process to recognize novel pharmacological and toxicological properties in small molecules by comparing their gene expression signatures with others in a database. A simple and robust method for connectivity mapping with increased specificity and sensitivity was recently developed, and its utility demonstrated using experimentally derived gene signatures. Results: This paper introduces sscMap (statistically significant connections' map), a Java application designed to undertake connectivity mapping tasks using the recently published method. The software is bundled with a default collection of reference gene-expression profiles based on the publicly available dataset from the Broad Institute Connectivity Map 02, which includes data from over 7000 Affymetrix microarrays, for over 1000 small-molecule compounds, and 6100 treatment instances in 5 human cell lines. In addition, the application allows users to add their custom collections of reference profiles and is applicable to a wide range of other 'omics technologies. Conclusions: The utility of sscMap is two fold. First, it serves to make statistically significant connections between a user-supplied gene signature and the 6100 core reference profiles based on the Broad Institute expanded dataset. Second, it allows users to apply the same improved method to custom-built reference profiles which can be added to the database for future referencing.

description: A hydro-acoustic imaging system was tested in a pilot study on distant localization of elements of the Baikal underwater neutrino telescope. For this innovative approach, based on broad band acoustic echo signals and strictly avoiding any active acoustic elements on the telescope, the imaging system was temporarily installed just below the ice surface, while the telescope stayed in its standard position at 1100 m depth. The system comprised an antenna with four acoustic projectors positioned at the corners of a 50 meter square; acoustic pulses were "linear sweep-spread signals" - multiple-modulated wide-band signals (10-22 kHz) of 51.2 s duration. Three large objects (two string buoys and the central electronics module) were localized by the 3D acoustic imaging, with a accuracy of ~0.2 m (along the beam) and ~1.0 m (transverse). We discuss signal forms and parameters necessary for improved 3D acoustic imaging of the telescope, and suggest a layout of a possible stationary bottom based 3D imaging setup. The presented technique may be of interest for neutrino telescopes of km3-scale and beyond, as a flexible temporary or as a stationary tool to localize basic telescope elements, while these are completely passive.

Un gruppo di scienziati russi ha analizzato tre cicli di attività solare dal 1976 al 2009, prevedendo l'inizio di un periodo di attività minima proprio in questi anni. Si potrebbe affermare che man mano che le macchie solari diminuiscono, le temperature sulla Terra si abbassano. L'attività solare è fondamentale per la vita sul nostro pianeta

La fisica che ha prodotto i superflare su KIC 9655129 è la stessa che governa l'attività del nostro Sole: secondo i ricercatori della Warwick la nostra stella ha le potenzialità giuste per produrre una bomba da un miliardo di megatoni che potrebbe causare un gigantesco blackout, qui, a Terra. Ma fortunatamente le probabilità che si verifichi un evento simile sono molto basse

description: The dynamics of an inhomogeneous universe is studied with the methods of Loop Quantum Cosmology as an example of the quantization of vacuum cosmological spacetimes containing gravitational waves (Gowdy spacetimes). The analysis performed at the effective level shows that: (i) The initial Big Bang singularity is replaced (as in the case of homogeneous cosmological models) by a Big Bounce, joining deterministically two large universes, (ii) the universe size at the bounce is at least of the same order of magnitude as that of the background homogeneous universe, (iii) for each gravitational wave mode, the difference in amplitude at very early and very late times has a vanishing statistical average when the bounce dynamics is strongly dominated by the inhomogeneities, whereas this average is positive when the dynamics is in a near-vacuum regime, so that statistically the inhomogeneities are amplified.

description: The synaptic GTPase-activating protein SynGAP is an important constituent of the postsynaptic compartment. Haploinsufficiency of the SYNGAP1 gene is associated with a neurodevelopmental disorder characterized by mental retardation, moderate to severe intellectual disability, global developmental delay, and a generalized form of epilepsy. Most of the studies on SYNGAP1 syndrome were performed in Syngap1 +/- and -/- mouse models. Although animal-based experiments have made significant contributions to understanding disease mechanisms, these models are limited when it comes to human conditions, primarily due to major disparities in physiology and development. Here, we set out to model this disorder using isogenic engineered SYNGAP1 haploinsufficient human pluripotent stem cells and forward programmed them into neurons for disease modeling. SYNGAP1 +/- glutamatergic neurons (iGlutNs) showed increased Ras-GTP and phospho-Erk concentration, alterations in pathways downstream of SynGAP. These pathway alterations may contribute to increased neural complexity, as evidenced by the longer and more intricate dendritic structures observed in our model. At the synaptic level, we noted a general increase in spine surface area and length. Moreover, there was a rise in the proportion of mature, mushroom-shaped spines, suggesting enhanced differentiation. Electrophysiologically, at the network level, the SYNGAP1 +/- neurons showed a higher network burst frequency with concurrently shorter network bursts and fewer spikes per network burst, with overall lower synchrony. Additionally, SYNGAP1 +/- neurons demonstrated elevated expression of AMPA receptors, potentially leading to postsynaptic saturation. This saturation could result in the occlusion of long-term potentiation (LTP), a phenomenon that was confirmed through patch-clamp experiments. The increased network burst frequency and duration might be a phenotype originating from glutamatergic neurons, while the decreased number of spikes might evolve from GABAergic neurons, suggesting that SYNGAP1 also plays a role in inhibitory neurons. The pathoelectrophysiological network pattern might resemble the phenotypes to those found in primary neurons from mouse epilepsy models. Overall, these findings indicate that SynGAP, through alterations in RasGTP and Erk concentration may promote spine growth and synaptic strength through multiple pathways, including actin polymerization and AMPAR insertion. This ultimately may lead to impaired LTP resulting in altered neuronal activity.

description: Multirotor aerial robots are becoming widely used for the inspection of powerlines. To enable continuous, robust inspection without human intervention, the robots must be able to perch on the powerlines to recharge their batteries. Highly versatile perching capabilities are necessary to adapt to the variety of configurations and constraints that are present in real powerline systems. This paper presents a novel perching trajectory generation framework that computes perception-aware, collision-free, and dynamically-feasible maneuvers to guide the robot to the desired final state. Trajectory generation is achieved via solving a Nonlinear Programming problem using the Primal-Dual Interior Point method. The problem considers the full dynamic model of the robot down to its single rotor thrusts and minimizes the final pose and velocity errors while avoiding collisions and maximizing the visibility of the powerline during the maneuver. The generated maneuvers consider both the perching and the posterior recovery trajectories. The framework adopts costs and constraints defined by efficient mathematical representations of powerlines, enabling online onboard execution in resource-constrained hardware. The method is validated on-board an agile quadrotor conducting powerline inspection and various perching maneuvers with final pitch values of up to 180 degrees.

description: How particular bonds form in quantum materials has been a long-standing puzzle. Two key concepts dealing with charge degrees of freedom are dimerization (forming metal-metal bonds) and charge ordering (CO). Since the 1930s, these two concepts have been frequently invoked to explain numerous exciting quantum materials, typically insulators. Here we report dimerization and CO within the dimers coexisting in metallic NaRu$_2$O$_4$. By combining high-resolution x-ray diffraction studies and theoretical calculations, we demonstrate that this unique phenomenon occurs through a new type of bonding, which we call Z-type ordering. The low-temperature superstructure has strong dimerization in legs of zigzag ladders, with short dimers in legs connected by short zigzag bonds, forming Z-shape clusters: simultaneously, site-centered charge ordering also appears. Our results demonstrate the yet unknown flexibility of quantum materials with the intricate interplay among orbital, charge, and lattice degrees of freedom.

description: Diagnosing errors in spaceborne oceanic precipitation estimates is difficult due tocomplicated multi-satellite algorithms and limited surface-based measurements. The Global Precipitation Measurement (GPM) mission helps to alleviate these challenges with NASA’s Integrated Multi-satellitE Retrievals for GPM (IMERG) product, which is transparently designed to encourage community validation activities, and the GPM Validation Network, which collects observations across global precipitation regimes from over 100 ground-based weather radars to serve as reference datasets for the GPM precipitation products. This study uses the GPM Validation Network’s oceanic precipitation observations from 32 island and coastal radars to diagnose the performance of IMERG V06B & V07B Final Run products during GPM Microwave Imager (GMI) overpasses (i.e., IMERG-GMI) in the period June 2014 – September 2021. Errors are traced from the input Level-2 (satellite footprint) Goddard Profiling Algorithm climate (GPROF-CLIM) GMI product through the successive gridding, calibration and precipitation distribution restoration steps of IMERG’s Level-3 (gridded) algorithm. Results highlight that IMERG-GMI V07B outperforms V06B in detecting and quantifying oceanic precipitation, with a significant improvement over high-latitude ocean (V06B: +143%; V07B: +50%). Furthermore, there is a clear oceanic latitudinal trend in the mean relative bias of IMERG-GMI V07B (high-latitude: +50%; mid-latitude: +10%; tropical: ?41%), which largely traces back to GPROF-CLIM V07 (high-latitude: +22%; mid-latitude: ?8%; tropical: ?44%), with bias differences driven by IMERG’s passive microwave calibration scheme. This error tracing approach supports future IMERG algorithm developments by disentangling how algorithm steps enhance or mitigate errors.

description: (Abridged) We carried out an extensive search to identify the counterparts of all the sources listed in the WMAP 3-yr catalogue using literature and archival data. Our work led to the identification of 309 WMAP sources, 98% of which are blazars, radio quasars or radio galaxies. At present, 15 objects still remain without identification due to the lack of optical spectroscopic data or a clear radio counterpart. Our results allow us to define a flux limited sample of 203 high Galactic latitude microwave sources ($f_{41GHz} \ge 1$ Jy, $|b_{\rm II}| > 15^\circ$) which is virtually completely identified (99%). The microwave band is ideally suited for blazar statistical studies since this is the part of the em spectrum that is least affected by the superposition of spectral components of different origin. Using this data-set we derived number counts, luminosity functions and cosmological evolution of blazars and radio galaxies at microwave frequencies. Our results are in good agreement with those found at radio frequencies. The 5 GHz bivariate blazar luminosity functions are similar to those derived from the DXRBS survey, which shows that this sample is representative of the blazar population at 41 GHz. Microwave selected broad- lined quasars are about 6 times more abundant than BL Lacs, a ratio that is similar to, or larger than, that seen at radio and gamma-ray frequencies, once spectral selection effects are taken into account. This strongly suggests that the mechanism responsible for the generation of gamma-rays is, at first order, the same in all blazar types. Our results confirm the findings of Giommi & Colafrancesco (2004, 2006) that blazars and radio galaxies are the largest contaminants of the CMB anisotropy maps. We predict that these sources are also bright gamma-ray sources, most of which will be detected by AGILE and FERMI.

description: Using the techniques of radio-frequency resonance spectroscopy, experimental studies of the nuclear spin resonance spectrum of Al²⁷ in single crystals of spodumene (LiAl(SiO₃)₂) have been carried out over a wide-range of externally applied magnetic field. In spodumene, interactions of the magnetic dipole moment with an external magnetic field, and also interactions of the electric quadrupole moment with the crystalline electrostatic field gradient can affect the energies of Al²⁷ nuclei. We define R as the ratio of magnetic to electrostatic interaction energies. The object of this thesis has been to measure experimentally a nuclear resonance spectrum over a wide enough range of magnetic field to link the regions where R is much greater than or much less than unity. Much experimental data is available in the literature for crystals where R differs appreciably from unity, but no experimental results have been given before for the intermediate region where R is of the order of unity and where the spectrum is more complex. Using data obtained from high field measurements in spodumene by Petch and Cranna, Lamarche has calculated energy levels by exact diagonalization of the Hamiltonian over a wide range of R values for a particular orientation of the spodumene crystal in a magnetic field. Calculations for other orientations have been made using electronic computers at the University of Toronto and at the University of British Columbia. Several of the predicted resonances have been observed. One transition has been observed over a range of magnetic field covering the region from R much less than unity to R much greater than unity. Resonance frequencies observed have been in good agreement with calculated transition frequencies. A new method of using a knowledge of the spin eigenstates to predict signal voltage for an induction spectrometer has been checked at values for R of the order of unity. It gives good agreement with experimental signal voltage measurements. Pure quadrupole transitions have been observed in spodumene at 751.5 kc and 793.5 kc with an estimated probable error of 2 kc, using an induction spectrometer with Zeeman modulation. These measurements are the lowest frequency pure quadrupole resonances reported to date.
