Investigation of Systematic Bias in Radiometric Diameter Determination of Near-Earth Asteroids: the Night Emission Simulated Thermal Model (NESTM)

description: The Near-Earth Asteroid Thermal Model (NEATM, Harris, 1998) has proven to be a reliable simple thermal model for radiometric diameter determination. However NEATM assumes zero thermal emission on the night side of an asteroid. We investigate how this assumption affects the best-fit beaming parameter, overestimates the effective diameter and underestimates the albedo at large phase angles, by testing NEATM on thermal IR fluxes generated from simulated asteroid surfaces with different thermal inertia. We compare NEATM to radar diameters and find that NEATM overestimates the diameter when the beaming parameter is fitted to multi-wavelength observations and underestimates the diameter when the default beaming parameter is used. The Night Emission Simulated Thermal Model (NESTM) is introduced. NESTM models the night side temperature as an iso-latitudinal fraction (f) of the maximum day side temperature (Maximum temperature calculated for NEATM with beaming parameter = 1). A range of f is found for different thermal parameters, which depend on the thermal inertia. NESTM diameters are compared with NEATM and radar diameters, and it is shown that NESTM may reduce the systematic bias in overestimating diameters. It is suggested that a version of the NESTM which assumes the thermal inertia = 200 S.I. units is adopted as a default model when the solar phase angle is greater than 45 degrees.

Guided resonances in photonic crystals with point-defected aperiodically-ordered supercells

description: In this paper, we study the excitation of guided resonances (GRs) in photonic-crystal slabs based on point-defected aperiodically-ordered supercells. With specific reference to perforated-slab structures and the Ammann-Beenker octagonal lattice geometry, we carry out full-wave numerical studies of the plane-wave responses and of the underlying modal structures, which illustrate the representative effects induced by the introduction of symmetry-preserving and symmetry-breaking defects. Our results demonstrate that breaking the supercell mirror symmetries via the judicious introduction of point-defects enables for the excitation of otherwise uncoupled GRs, with control on the symmetry properties of their field distributions, thereby constituting an attractive alternative to those GR-engineering approaches based on the asymmetrization of the hole shape. In this framework, aperiodically-ordered supercells seem to be inherently suited, in view of the variety of inequivalent defect sites that they can offer.

Air Shower Measurements with the LOPES Radio Antenna Array

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: LOPES is set up at the location of the KASCADE-Grande extensive air shower experiment in Karlsruhe, Germany and aims to measure and investigate radio pulses from Extensive Air Showers. Since radio waves suffer very little attenuation, radio measurements allow the detection of very distant or highly inclined showers. These waves can be recorded day and night, and provide a bolometric measure of the leptonic shower component. LOPES is designed as a digital radio interferometer using high bandwidths and fast data processing and profits from the reconstructed air shower observables of KASCADE-Grande. The LOPES antennas are absolutely amplitude calibrated allowing to reconstruct the electric field strength which can be compared with predictions from detailed Monte Carlo simulations. We report about the analysis of correlations present in the radio signals measured by the LOPES 30 antenna array. Additionally, LOPES operates antennas of a different type (LOPES-STAR) which are optimized for an application at the Pierre Auger Observatory. Status, recent results of the data analysis and further perspectives of LOPES and the possible large scale application of this new detection technique are discussed.

description: This paper presents a methodology to quantify the convective heat losses in a full-scale compartment fire
experiment, and presents an analysis of the key uncertainties in the experimental procedure, with the
purpose of reducing uncertainty, and establishing robust error bars to the methodology. Uncertainties in
the experimental flow measurements were assessed through a wind tunnel study of the bi-directional
probe-transducer assembly at a range of Reynolds numbers. It was shown that at low Reynolds numbers,
the probe-transducer assembly gains Reynolds dependence, for which the correction factor can be
described as a piecewise function over the voltage of the differential pressure transducer used, with a
minimum correction factor of 0.60. Numerical modelling in FDS is used to validate the assumptions
driving the proposed methodology, and to provide the upper bound to the methodology. Due to the
limited resolution of bi-directional probes in the experiment, the flow profile was mapped using a high
resolution of thermocouples positioned near the opening, which allowed for the definition of the thermal
interface height within the range (0.51-0.56)H0, which was in proximity to the numerically determined
neutral plane height within the range (0.61-0.64)H0. Based on the numerical study and the literature, static
inflows are assumed, and thus the convective heat losses through the opening are calculated. Similar to
the underpinning work of the Compartment Fire Framework for well-ventilated fires, convective heat
losses through the opening are calculated to account for 80% of the input fire. Sensitivity analyses of the
hot layer temperatures and the interface height reveal a key dependency of the total convective heat losses
to an accurate estimation of the interface height. The work presented herein will be utilised to characterise
the fire dynamics of a set of full-scale experiments in order provide an accurate representation of thermal
boundary conditions, either to the structure or out of the compartment, into adjacent spaces or windows.

Attesissima, anticipatissima, declamatissima – le aspettative per la prima “fotografia” di un buco nero erano ormai tali che alto era il rischio di restare delusi. Invece è un autentico capolavoro, una conquista dell’umanità che per essere apprezzata va posta a fianco non di rappresentazioni artistiche e simulazioni bensì di un’altra “fotografia”: quella di Nicéphore Niépce del 1826

Indistinguishability and Interference in the Coherent Control of Atomic and Molecular Processes

description: The subtle and fundamental issue of indistinguishability and interference between independent pathways to the same target state is examined in the context of coherent control of atomic and molecular processes, with emphasis placed on possible "which-way" information due to quantum entanglement established in the quantum dynamics. Because quantum interference between independent pathways to the same target state occurs only when the independent pathways are indistinguishable, it is first shown that creating useful coherence (as defined in the paper) between nondegenerate states of a molecule for subsequent quantum interference manipulation cannot be achieved by collisions between atoms or molecules that are prepared in momentum and energy eigenstates. Coherence can, however, be transferred from light fields to atoms or molecules. Using a particular coherent control scenario, it is shown that this coherence transfer and the subsequent coherent phase control can be readily realized by the most classical states of light, i.e., coherent states of light. It is further demonstrated that quantum states of light may suppress the extent of phase-sensitive coherent control by leaking out some which-way information while "incoherent interference control" scenarios proposed in the literature have automatically ensured the indistinguishability of multiple excitation pathways. The possibility of quantum coherence in photodissociation product states is also understood in terms of the disentanglement between photodissociation fragments. Results offer deeper insights into quantum coherence generation in atomic and molecular processes.

Representations of discrete symmetry operators in quantum field theory
Creators: name: Mariwalla, Kishin Hariram
Publisher: name: University of British Columbia
Year: 2012

description: The object of the work reported in this thesis was to construct and study the explicit representations of discrete symmetry operators (D.S.O.'s) in quantum field theory. In spite of the considerable importance of the D.S.O.'s in present day physics, not much has been reported in the systematic study of such representations. Furthermore, in the work reported hitherto, only incomplete representations for the operators of space inversion (⊓) particle conjugation (⌐) and time reversal ( T ) have been given. Starting from general considerations on invariance principles and infinitesimal transformations, with the associated conservation laws, a systematic procedure for constructing the representations of the D.S.O.'s has been formulated. The procedure consists in enumerating the bilinears in creation and annihilation operators. It is shown that eight symmetries are the only possible ones. In view of the TCP - theorem and the so called non-conservation of parity in weak interactions, the product operators, such as reflection ( ⋀ = ⊓ ⌐ ) and strong reflection (S = ⊓ ⌐ T), in addition to time reversal, should be considered as the most basic symmetries. Working in linear momentum representation, the unitary operators ⋀, ⊓, ⌐, E ( = identity) and the unitary factors of the antiunitary operators: S, I = ⊓ T, J = T ⌐ and T are constructed for the following free fields: (I) The non-hermitian scalar field representing, for example, kaons. (II) The electromagnetic field. (III) The four-component spinor field. The operators for the scalar field have also been worked out in the angular momentum representation. Using the anti-commutation relations for C.O.’s and A.O.’s, an alternate construction of D.S.O.'s of the Dirac field is exhibited. More than one representation has been given in each case. In addition a two dimensional matrix representation has been given. It is shown that by an appropriate unitary transformation these can be reduced to the ordinary form.

description: This paper describes the Maryland-Magellan Tunable Filter (MMTF) on the Magellan-Baade 6.5-meter telescope. MMTF is based on a 150-mm clear aperture Fabry-Perot (FP) etalon that operates in low orders and provides transmission bandpass and central wavelength adjustable from ~5 to ~15 A and from ~5000 to over ~9200 A, respectively. It is installed in the Inamori Magellan Areal Camera and Spectrograph (IMACS) and delivers an image quality of ~0.5" over a field of view of 27' in diameter (monochromatic over ~10'). This versatile and easy-to-operate instrument has been used over the past three years for a wide variety of projects. This paper first reviews the basic principles of FP tunable filters, then provides a detailed description of the hardware and software associated with MMTF and the techniques developed to observe with this instrument and reduce the data. The main lessons learned in the course of the commissioning and implementation of MMTF are highlighted next, before concluding with a brief outlook on the future of MMTF and of similar facilities which are soon coming on line.

description: Hypoxia plays a crucial role in malignant progression of solid tumors, including breast cancer, since neoplastic cells adapt to low oxygen availability by modulating the expression of genes involved in survival, proliferation, metabolic reprogramming, stem cell maintenance, EMT, angiogenesis, invasion and metastasis (1). Among the signaling molecules deregulated in breast tumors, the beta2 isoform of the phosphoi- nositide-dependent phospholipase C (PLC-β2) is expressed in the large majority of primary invasive tumors from all histological subtypes in which it strongly correlates with malignancy and with a poor prognosis (2). PLC-β2 is also expressed in breast tumor- derived cells, in which it improves proliferation and motility and sustains invasion capability (3). A decreased PLC-β2 expression is induced by hypoxia in the BT-474 and MCF7 cell lines, that is correlated with the hypoxia-induced modulation of the EMT markers E-cadherin and Vimentin, as well as of the stem cell marker CD133. In contrast, hypoxia induced the increase of PLC-β2 levels in MDA-MB-231 cells, in which it supports the hypoxia-related reorganization of actin cytoskeleton. In all examined cell lines, the prevention of the effects of hypoxia on PLC-β2 also reduced the recovery of HIF-1α, in turn able to exert a phenotype-related role in modulating EMT and expression of CD133 during the cell response to low oxygen. Our data highlighted a peculiar effect of low oxygen availability on PLC-β2 expression in breast tumor cells with different phenotypes and allocate PLC-β2 in the complex and interconnected transcriptional activity induced by hypoxia. Our results also suggest that the forced modulation of PLC-β2 programmed on the basis of the tumor phenotype may prevent malignant progression of breast neoplasia as a consequence of intra-tumoral hypoxia.

The electric potential in the neighbourhood of a thin slit
Creators: name: Allard, Jean-Louis
Publisher: name: University of British Columbia
Year: 2011

description: When a slit opening is made in a plane electrode forming the boundary between two unequal electric fields, a distortion of the fields occurs. This paper studies the influence of the slit opening on the electrical potential distribution on both sides of the slit. A theory is developed for calculating the potential at any point, and from it two methods are derived for finding curves of equal potential disturbance. Several computed curves are presented for each method. The curves suggest a simple graphical construction for approximating the potential disturbance at points not too near the slit. Because the potential disturbance is the same at image points on either side of the slit, it is found that all the important formulas can be expressed in terms of distances, without regard to sign. To facilitate the reproduction or extension of this work, a computer program in the widely used Fortran language is given for the simpler of the two methods.

description: Osteogenic differentiation process consists of integration of several signaling pathways such as TGF-β, BMP, Wnt/β-catenin (1,2) and Notch which orchestrate to regulate differentiation of mesenchymal stem cells. To date, the role of Notch signaling pathway, which is known to regulate cell fate decision and differentiation in several cell types is still poorly understood in osteogenic differentiation, as controversial results have been described. Notch signaling is initiated by binding a Notch ligand (JAGGED and Delta-Like) to a cell surface Notch receptor (NOTCH 1–4), resulting in a multistep cleavage of receptor and releasing Notch intracellular domain (NICD) which translocates to the nucleus and activates transcription of downstream Notch target genes, such as the Hes/Hey family (3). The aim of this study was to investigate the involvement of Notch signaling in the osteogenic dif- ferentiation. To this purpose, we stimulated human immature osteoblast cell line (MG-63) with osteogenic medium for 28 days, in the absence and in the presence of DAPT, a gamma-secretase inhibitor used to block Notch signaling. At different days during differentia- tion, we investigated biochemical osteogenic markers such as Alkaline phosphatase (ALP) activity, osteocalcin (OC) levels, mineralization as well as gene expression of osteogenic transcription factors including Runx2, DLX5, Osterix and the gene Collagen I (CollI). Further, the gene expression of Notch receptors (Notch1-4), their ligands (Jagged1 and DLL4) and nuclear target genes (Hey1, Hey2, hes1, Hes5) was evaluated. As expected, our results showed that during osteogenic differentiation of MG63, osteogenic markers and transcription factors were upregulated. In addition, Notch2, Notch4 and Hey1 were overexpressed in different stages of differentiation. Differently, Notch1, Notch3 and Hes5 were down-regulated. No differences were observed about Notch ligands. Treatment of cells with DAPT, impaired osteogenic differentiation by reducing the main osteogenic markers such as ALP, OC, Coll I, , Runx2, DLX5 and Osterix as well as Hey1 nuclear gene. These results appear to confirm a significant role of Notch signaling during osteogenic differentiation by the activation of the canonical pathway with the main involvement of Notch 2 and Notch 4 receptors and Hey1 as nuclear target gene. In clinics these data may be relevant as they propose that Notch pathway can be used as a therapeutic target during bone defects and pathologies.

description: We have recently characterized and differentiated towards endodermal and mesoder- mal lineages progenitor cells of the adult rat thyroid, expressing multipotency markers [1]. We have now assessed their clonogenicity, extent of side population, consistency of stem cell marker expression, and commitment to either follicular or hepatocyte-like lineages when in monolayer (2D), and suspension or Matrigel (3D). Colony forming unit (CFU)-like cultures were obtained by long-term subcultures of primary rat thyroid cells, under starvation conditions. CFU-like cultures seeded in Petri dishes by limiting dilution (1 cell / cm2) were observed to give rise to toluidine blue-positive, individual clones. In these cultures, quantitative densitometric analysis of immunoblotted Oct-3/4, Sca1, and GATA4 revealed an increase in stem cell markers ranging from 95% to 270% with respect to standard, primary thyroid cultures. In addition, using three different analytical techniques including DyeCycle Violet staining by flow cytometry, ABCG2 immunocytochemistry, and Hoechst 33342 histochemistry + the ABCG2 inhibitor, verapamil a side population involving 1-2% of CFU-like cultures was detected. Then, CFU-like cultures were differentiated using TSH, either in 2D or in 3D. Differentiated adherent cells resulted immunopositive for thyrocyte markers including thyroglobulin (TG), sodium-iodide symporter (NIS), and thyroperoxidase (TPO). Differentiation in suspension and in Matrigel gave rise to follicles with cells having ultrastructural features consistent with thyrocytes, and immunoreactivity (IR) for TG, NIS, and TPO. Finally, CFU-like cultures were differentiated in adherence to hepatocyte-like cells, resulting in pre-hepatocyte morphology, high periodic acid-Schiff reaction, and IR for α-fetoprotein and albumin. We conclude that our CFU-like thyroid cultures are enriched with a multipotent, stem cell population whose hepatic differentiation capacity has been revealed for the first time.

description: Supermassive black hole binaries (SMBHBs) with masses in the range 10^4-10^7 M_sun/(1+z), produced in galaxy mergers, are thought to complete their coalescence due to the emission of gravitational waves (GWs). The anticipated detection of the GWs by the LISA will constitute a milestone for fundamental physics and astrophysics. While the GW signatures themselves will provide a treasure trove of information, if the source can be securely identified in electromagnetic (EM) bands, this would open up entirely new scientific opportunities, to probe fundamental physics, astrophysics, and cosmology. We discuss several ideas, involving wide-field telescopes, that may be useful in locating electromagnetic counterparts to SMBHBs detected by LISA. In particular, the binary may produce a variable electromagnetic flux, such as a roughly periodic signal due to the orbital motion prior to coalescence, or a prompt transient signal caused by shocks in the circumbinary disk when the SMBHB recoils and "shakes" the disk. We discuss whether these time-variable EM signatures may be detectable, and how they can help in identifying a unique counterpart within the localization errors provided by LISA. We also discuss a possibility of identifying a population of coalescing SMBHBs statistically, in a deep optical survey for periodically variable sources, before LISA detects the GWs directly. The discovery of such sources would confirm that gas is present in the vicinity and is being perturbed by the SMBHB - serving as a proof of concept for eventually finding actual LISA counterparts.

description: One solution to the so-called problem of time is to construct certain Dirac observables, sometimes called evolving constants of motion. There has been some discussion in the literature about the interpretation of such observables, and in particular whether single Dirac observables can be measured. Here we clarify the situation by describing a class of interactions that can be said to implement measurements of such observables. Along the way, we describe a useful notion of perturbation theory for the rigging map eta of group averaging (sometimes loosely called the physical state "projector"), which maps states from the auxiliary Hilbert space to the physical Hilbert space.
