description: A simple economic graphite pencil electrode (GPE) was used for analysis of cardioselective, hydrophilic-adrenoreceptor blocking agent, acebutolol (ACBT) using the cyclic voltammetric, linear sweep voltammetric, differential pulse voltammetric (DPV), and square-wave voltammetric (SWV) techniques. The dependence of the current on pH, concentration, and scan rate was investigated to optimize the experimental condition for determination of ACBT. The electrochemical behavior of the ACBT at GPE was a diffusion-controlled process. A probable electro-redox mechanism was proposed. Under the optimal conditions, the anodic peak current was linearly proportional to the concentration of ACBT in the range from 1.00 to 15.0 μM with a limit of detection 1.26 × 10−8 M for DPV and 1.28 × 10−8 M for the SWV. This method was applied for quantitative determination of the ACBT levels in urine as real samples. The obtained recovery ranges for ACBT in urine were from 95.4 to101% as found by the standard addition technique. Further interference study was also carried with some common interfering substances.
Romeo and Juliet and its Intertexts

description: It sometimes happens that texts categorized as sources for a Shakespearean play are in fact more or less overtly invoked by the work itself, and should accordingly be regarded not only as genealogical antecedents or imaginative influences but as implicit intertexts in relation to which it elaborates its own meanings. Such is the case with some of the works inspiring Romeo and Juliet, and in particular with the story of Pyramus and Thisbe contained in Ovid’s Metamorphoses. This tragic little tale is frequently cited as being that from which Romeo and Juliet ultimately derives, and what is of considerable interest in this connection is that it is also explicitly referenced in A Midsummer Night’s Dream, a play that might in certain respects be read as a comic pendant to Shakespeare’s Veronese tragedy and indeed as a kind of intertext in its own right. The story of Pyramus and Thisbe is however one that has appeared in a variety of guises in the course of the centuries, and to the degree that these versions are also echoed in Romeo and Juliet they too might be considered to constitute intertexts in the broadest sense of the term.

description: One of the crucial steps in the design of an integrated circuit is the minimization of heating and temperature non-uniformity. Current temperature calculation methods, such as finite element analysis and resistor networks have considerable computation times, making them incompatible for use in routing and placement optimization algorithms. In an effort to reduce the computation time, we have developed a new method, deemed power blurring, for calculating temperature distributions using a matrix convolution technique in analogy with image blurring. For steady state analysis, power blurring was able to predict hot spot temperatures within 1 degree C with computation times 3 orders of magnitude faster than FEA. For transient analysis the computation times where enhanced by a factor of 1000 for a single pulse and around 100 for multiple frequency application, while predicting hot spot temperature within about 1 degree C. The main strength of the power blurring technique is that it exploits the dominant heat spreading in the silicon substrate and it uses superposition principle. With one or two finite element simulations, the temperature point spread function for a sophisticated package can be calculated. Additional simulations could be used to improve the accuracy of the point spread function in different locations on the chip. In this calculation, we considered the dominant heat transfer path through the back of the IC chip and the heat sink. Heat transfer from the top of the chip through metallization layers and the board is usually a small fraction of the total heat dissipation and it is neglected in this analysis.

description: Originally introduced in connection with general relativistic Coriolis forces, the term $\textit{frame-dragging}$ is associated today with a plethora of effects related to the off-diagonal element of the metric tensor. It is also frequently the subject of misconceptions leading to incorrect predictions, even of nonexistent effects. We show that there are three different levels of frame-dragging corresponding to three distinct gravitomagnetic objects: gravitomagnetic potential 1-form, field, and tidal tensor, whose effects are independent, and sometimes opposing. It is seen that, from the two analogies commonly employed, the analogy with magnetism holds strong where it applies, whereas the fluid-dragging analogy (albeit of some use, qualitatively, in the first level) is, in general, misleading. Common misconceptions (such as viscous-type "body-dragging") are debunked. Applications considered include rotating cylinders (Lewis-Weyl metrics), Kerr, Kerr-Newman and Kerr-dS spacetimes, black holes surrounded by disks/rings, and binary systems.

A Statistical Study on Solar Active Regions Producing Extremely Fast Coronal Mass Ejections

description: We present a statistical result on the properties of solar source regions that have produced 57 fastest front-side coronal mass ejections (CMEs) (speed 1500 km/s) occurred from 1996 June to 2007 January. The properties of these fast-CME-producing regions, 35 in total, are compared with those of all 1143 active regions (ARs) in the period studied. An automated method, based on SOHO/MDI magnetic synoptic charts, is used to select and characterize the ARs. For each AR, a set of parameters are derived including the areas (positive, negative and total, denoted by A_P, A_N and A_T respectively), the magnetic fluxes (positive, negative and total, F_P, F_N and F_T respectively), the average magnetic field strength (B_avg), quasi-elongation (e) characterizing the overall shape of the AR, the number and length of polarity inversion lines (PILs, or neutral lines, N_PIL and L_PIL respectively), and the average and maximum of magnetic gradient on the PILs (GOP_avg and GOP_max respectively). Our statistical analysis shows a general trend between the scales of an AR and the likelihood of producing a fast CME, i.e., the larger the geometric size (A_T), the larger the magnetic flux (F_T), the stronger the magnetic field (B_avg), and/or the more complex the magnetic configuration (N_PIL and L_PIL), then the higher the possibility of producing a fast CME. When all ARs are sorted into three equally-numbered groups with low, middle and high values of these parameters, we find that, for all these AR parameters, more than 60% of extremely fast CMEs are from the high-value group. The two PIL parameters are the best indicators of producing fast CMEs, with more than 80% from the high value group.

description: Given a knot K we may construct a group G_n(K) from the fundamental group of K by adjoining an nth root of the meridian that commutes with the corresponding longitude. These "generalised knot groups" were introduced independently by Wada and Kelly, and contain the fundamental group as a subgroup. The square knot SK and the granny knot GK are a well known example of a pair of distinct knots with isomorphic fundamental groups. We show that G_n(SK) and G_n(GK) are non-isomorphic for all n>1. This confirms a conjecture of Lin and Nelson, and shows that the isomorphism type of G_n(K), n>1, carries more information about K than the isomorphism type of the fundamental group. An appendix by David Savitt contains some results on representations of the trefoil group in PSL(2,p) that are needed for the proof.

description: The electrochemical oxidation of carbenicillin disodium salt (CDS) at gold electrode has been investigated for the first time using cyclic, linear sweep, and differential pulse voltammetric techniques. The dependence of the current on pH, concentration, and scan rate were investigated to optimize the experimental conditions for the determination of carbenicillin. The anodic peak was characterized and process was adsorption-controlled. The number of electrons transferred in the oxidation was calculated. A differential pulse voltammetry method with good precision and accuracy was developed for the determination of carbenicillin. The anodic peak current varied linearly with carbenicillin concentration in the range 1.0 × 10−4 M to 5.0 × 10−6 M with a limit of detection (LOD) of 6.859 × 10−7 M and limit of quantification (LOQ) of 2.286 × 10−6 M. This method can be employed in clinical analysis, quality control, and routine determination of drugs in pharmaceutical analysis.

description: Proton beam therapy can potentially offer improved treatment for cancers of the head and neck and in paediatric patients. There has been a sharp uptake of proton beam therapy in recent years as improved delivery techniques and patient benefits are observed. However, treatments are currently planned using conventional x-ray CT images due to the absence of devices able to perform high quality proton computed tomography (pCT) under realistic clinical conditions. A new plastic-scintillator-based range telescope concept, named ASTRA, is proposed here to measure the proton's energy loss in a pCT system. Simulations conducted using GEANT4 yield an expected energy resolution of 0.7\%. If calorimetric information is used the energy resolution could be further improved to about $0.5\%$. In addition, the ability of ASTRA to track multiple protons simultaneously is presented. Due to its fast components, ASTRA is expected to reach unprecedented data collection rates, similar to $10^8$ protons/s. The performance of ASTRA has also been tested by simulating the imaging of phantoms. The results show excellent image contrast and relative stopping power reconstruction.

description: This work builds on the previous introduction [1] of a coupled experimental-computational system devised to fully characterize the thermal behavior of complex 3D submicron electronic devices. The new system replaces the laser-based surface temperature scanning approach with a CCD camera-based approach. As before, the thermo-reflectance thermography system is used to non-invasively measure with submicron resolution the 2D surface temperature field of an activated device. The measured temperature field is then used as input for an ultra-fast inverse computational solution to fully characterize the thermal behavior of the complex three-dimensional device. For the purposes of this investigation, basic micro-heater devices were built, activated, and measured. In order to quantitatively validate the coupled experimental-computational system, the system was used to extract geometric features of a known device, thus assessing the system's ability to combine measured experimental results and computations to fully characterize complex 3D electronic devices.

title: Aural Architecture Practice: Creative Approaches for an Ecology of Affect
Creators: name: Martinho, Claudia
Publisher: name: Goldsmiths, University of London
Year: 2019

description: While the acoustic environment and urban soundscapes shape our everyday
life, architecture practice usually neglects the experience of acoustic space in its
design process. My research addressed the challenge of integrating spatial
acoustics and the experience of environmental sound in architecture practice.
Drawing from acoustic ecology, creative approaches embody the aural
experience of the environment into the design process of architecture. The
research was guided by my explorations of a site-oriented aural architecture
practice, to create unusual encounters and connections between human and
non-human beings, for their relationship through the acoustic space. It
experimented with the physical experience of vibrational forces in environmental
sound, enhanced by acoustic resonance.

The research was carried out by the creation of four artworks, employed as
practical case studies, to experiment with concepts such as: resonant
soundscape, space as resonator (Vibrational Fields), space as a dynamic
relation (Radio Sonores), soundscape for attunement (Shores) and space as
energetic geometry (Passage). The artworks were used to develop sets of
design methods to draw an aural architecture intervention. The first set guides
the experience of site through context analysis, participation, soundwalking,
field recording and sensory variation, for a transformation of the ambiance
dynamic, to accentuate differences and multiple relationships. The second set
offers different approaches in designing aural architecture through the
recomposition of urban soundscape and architectural agency based in
resonance, dynamic relation and energetic geometry, for an operation of
translation. The third set concerns the acoustic spatialisation of vibrational
forces, to open communication channels and symbiotic relationships, for an
operation of attunement. My research explored the enhancement of an innate
capacity of attunement (Morton 2014) to self and other beings (human, nonhuman).
It resulted in the creation of a diversity of experiences of environmental
sound, as a way to foster an ecology of affect.
Thermal Transient Multisource Simulation Using Cubic Spline Interpolation of Zth Functions

description: This paper presents a very straightforward method to compute the transient thermal response to arbitrary power dissipation profiles in electronic devices with multiple heat sources. Using cubic spline interpolation of simulated or measured unit power step response curves (Zth-functions), additional errors due to model reduction can be avoided. No effort has to be spent on the generation of compact models. The simple analytic form of the interpolating splines can be exploited to evaluate the convolution integral of the Zth-functions with arbitrary power profiles at low computational costs. An implementation of the algorithm in a spreadsheet program (EXCEL) is demonstrated. The results are in very good agreement with temperature profiles computed by transient Finite Element simulation but can be obtained in a fraction of the time.

description: A measurement of the cross section of the associated production of a single top quark and a W boson in final states with a muon or electron and jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV is presented. The data correspond to an integrated luminosity of 36 fb$^{-1}$ collected with the CMS detector at the CERN LHC in 2016. A boosted decision tree is used to separate the tW signal from the dominant $\mathrm{t\bar{t}}$ background, whilst the subleading W+jets and multijet backgrounds are constrained using data-based estimates. This result is the first observation of the tW process in final states containing a muon or electron and jets, with a significance exceeding 5 standard deviations. The cross section is determined to be 89 $\pm$ 4 (stat) $\pm$ 12 (syst) pb, consistent with the standard model.

description: Here we show that precise Gaia EDR3 proper motions have provided robust estimates of 3D velocities, angular momentum and total energy for 40 Milky Way dwarfs. The results are statistically robust and are independent of the Milky Way mass profile. Dwarfs do not behave like long-lived satellites of the Milky Way because of their excessively large velocities, angular momenta, and total energies. Comparing them to other MW halo population, we find that many are at first passage, $\le$ 2 Gyr ago, i.e., more recently than the passage of Sagittarius, $\sim$ 4-5 Gyr ago. We suggest that this is in agreement with the stellar populations of all dwarfs, for which we find that a small fraction of young stars cannot be excluded. We also find that dwarf radial velocities contribute too little to their kinetic energy when compared to satellite systems with motions only regulated by gravity, and some other mechanism must be at work such as ram pressure. The latter may have preferentially reduced radial velocities when dwarf progenitors entered the halo until they lost their gas. It could also explain why most dwarfs lie near their pericenter. We also discover a novel large scale structure perpendicular to the Milky Way disk, which is made by 20% of dwarfs orbiting or counter orbiting with the Sagittarius dwarf.

description: The local structure of V$_{2}$O$_{3}$, an archetypal strongly correlated electron system that displays a metal-insulator transition around 160 K, has been investigated via pair distribution function (PDF) analysis of neutron and x-ray total scattering data. The rhombohedral-to-monoclinic structural phase transition manifests as an abrupt change on all length scales in the observed PDF. No monoclinic distortions of the local structure are found above the transition, although coexisting regions of phase-separated rhombohedral and monoclinic symmetry are observed between 150 K and 160 K. This lack of structural fluctuations above the transition contrasts with the known presence of magnetic fluctuations in the high-temperature state, suggesting that the lattice degree of freedom plays a secondary role behind the spin degree of freedom in the transition mechanism.

We also observed that the average value of v, obtained under applied electric field (Eapp),showed creep behavior: i.e. ~ exp(-E0/Eapp)^$μ$ with an exponent $μ$ of 0.9 $\pm$ 0.1 and an activation field E0 of about 700 kV/cm.

description: L’objectif de ce papier est de voir l’influence du développement du secteur financier Congolais (Indice de la finance intermédiée et le crédit bancaire au secteur privé sur le PIB) dans l’efficacité de la politique monétaire (Inflation) menée par la Banque Centrale du Congo (BCC) afin de comprendre comment les politiques monétaires et les réformes du secteur financier peuvent contribuer à la croissance économique et à la stabilité financière de la RDC. Pour atteindre cet objectif, nous spécifions et estimons un modèle Autorégressif à retards échelonnés (ARDL) sur des données trimestrielles allant du premier trimestre 2002 au quatrième trimestre 2021. Les principaux résultats de cette recherche sont les suivants : Premièrement, le Test de causalité au sens de Toda-Yamamoto (1995) montre une causalité unidirectionnelle partant du Développement financier (CRDPIB) vers l’inflation. Aussi, ce même test atteste un effet feed-back entre le développement financier et la croissance économique. Deuxièmement, après estimation du modèle, les résultats attestent que le développement financier exerce un effet négatif sur l’efficacité de la politique monétaire, et ce dans une dynamique de court terme et de long terme. Une augmentation de l’importance relative de l’activité du secteur financier dans l’économie entraîne un refrènement du niveau de l’inflation. Cela démontre une relation importante entre le secteur financier développé et la stabilité des prix dans une économie. Une telle corrélation suggère que lorsque le système financier est bien développé, il peut mieux canaliser l'argent vers des investissements productifs et faciliter la transmission efficace de la politique monétaire. Cela permet à la banque centrale d'exercer un meilleur contrôle sur la masse monétaire en circulation, ce qui contribue à maîtriser l’inflation.

description: There is mounting evidence that neutrinos undergo fast flavor conversion (FFC) in core-collapse supernova (CCSN). In this letter, we investigate the roles of stellar rotation on the occurrence of FFC by carrying out axisymmetric CCSN simulations with full Boltzmann neutrino transport. Our result suggests that electron neutrino lepton number (ELN) angular crossings, which are the necessary and sufficient condition to trigger FFC, preferably occur in the equatorial region for rotating CCSNe. By scrutinizing the neutrino--matter interaction and neutrino radiation field, we find some pieces of evidence that the stellar rotation facilitates the occurrence of FFC. The low-electron-fraction region in the post-shock layer expands by centrifugal force, enhancing the disparity of neutrino absorption between electron-type neutrinos ($ν_{\rm e}$) and their anti-particles ($\barν_{\rm e}$). This has a significant impact on the angular distribution of neutrinos in momentum space, in which $ν_{\rm e}$ tends to be more isotropic than $\barν_{\rm e}$; consequently, ELN crossings emerge. The ELN crossing found in this study is clearly associated with rotation, which motivates further investigation on how the subsequent FFC influences explosion dynamics, nucleosynthesis, and neutrino signals in rotating CCSNe.

description: We report an experimental demonstration of entanglement swapping over two quantum stages. By successful realizations of two cascaded photonic entanglement swapping processes, entanglement is generated and distributed between two photons, that originate from independent sources and do not share any common past. In the experiment we use three pairs of polarization entangled photons and conduct two Bell-state measurements (BSMs) one between the first and second pair, and one between the second and third pair. This results in projecting the remaining two outgoing photons from pair 1 and 3 into an entangled state, as characterized by an entanglement witness. The experiment represents an important step towards a full quantum repeater where multiple entanglement swapping is a key ingredient.

description: We present maps of 7.78 square degrees of the Lupus molecular cloud complex at 24, 70, and $160\:μ$m. They were made with the Spitzer Space Telescope's Multiband Imaging Photometer for Spitzer (MIPS) instrument as part of the Spitzer Legacy Program, ``From Molecular Cores to Planet-Forming Disks'' (c2d). The maps cover three separate regions in Lupus, denoted I, III, and IV. We discuss the c2d pipeline and how our data processing differs from it. We compare source counts in the three regions with two other data sets and predicted star counts from the Wainscoat model. This comparison shows the contribution from background galaxies in Lupus I. We also create two color magnitude diagrams using the 2MASS and MIPS data. From these results, we can identify background galaxies and distinguish them from probable young stellar objects. The sources in our catalogs are classified based on their spectral energy distribution (SED) from 2MASS and Spitzer wavelengths to create a sample of young stellar object candidates. From 2MASS data, we create extinction maps for each region and note a strong corresponence between the extinction and the $160\:μ$m emission. The masses we derived in each Lupus cloud from our extinction maps are compared to masses estimated from $^{13}$CO and C$^{18}$O and found to be similar to our extinction masses in some regions, but significantly different in others. Finally, based on our color-magnitude diagrams, we selected 12 of our reddest candidate young stellar objects for individual discussion. Five of the 12 appear to be newly-discovered YSOs.

description: This work introduces a thermoreflectance-based system designed to measure the surface temperature field of activated microelectronic devices at submicron spatial resolution with either a laser or a CCD camera. The article describes the system, outlines the measurement methodology, and presents validation results. The thermo-reflectance thermography (TRTG) system is capable of acquiring device surface temperature fields at up to 512x512 points with 0.2 $μ$m resolution. The setup and measurement methodology are presented, along with details of the calibration process required to convert changes in measured surface reflectivity to absolute temperatures. To demonstrate the system's capabilities, standard gold micro-resistors are activated and their surface temperature fields are measured. The results of the CCD camera and our existing laser-based measurement approaches are compared and found to be in very good agreement. Finally, the system is validated by comparing the temperatures obtained with the TRTG method with those obtained from electrical resistance measurements.

SMA observations of Infrared Dark Clouds: A tale of two cores

description: We present high-angular resolution sub-millimeter continuum images and molecular line spectra obtained with the SMA toward two massive cores that lie within Infrared Dark Clouds; one actively star-forming (G034.43+00.24 MM1) and the other more quiescent (G028.53-00.25 MM1). The high-angular resolution sub-mm continuum image of G034.43+00.24 MM1 reveals a compact (~0.03 pc) and massive (~29 Msun) structure while the molecular line spectrum shows emission from numerous complex molecules. Such a rich molecular line spectrum from a compact region indicates that G034.43+00.24 MM1 contains a hot molecular core, an early stage in the formation of a high-mass protostar. Moreover, the velocity structure of its 13CO(3-2) emission indicates that this B0 protostar may be surrounded by a rotating circumstellar envelope. In contrast, the sub-mm continuum image of G028.53-00.25 MM1 reveals three compact (<0.06 pc), massive (9-21 Msun) condensations but with no lines detected in its spectrum. We suggest that the core G028.53-00.25 MM1 is in a very early stage in the high-mass star-formation process; its size and mass are sufficient to form at least one high-mass star, yet it shows no signs of localized heating. Because the combination of high velocity line wings with a large IR-mm bolometric luminosity (~100 Lsun) indicates that this core has already begun to form accreting protostars, we speculate that the condensations may be in the early phase of accretion and may eventually become high-mass protostars. We, therefore, have found the possible existence of two high-mass star-forming cores; one in a very early phase of star-formation and one in the later hot core phase. Together the properties of these two cores support the idea that the earliest stages of high-mass star-formation occur within IRDCs.

description: A simple Bayesian approach to nonparametric regression is described using fuzzy sets and membership functions. Membership functions are interpreted as likelihood functions for the unknown regression function, so that with the help of a reference prior they can be transformed to prior density functions. The unknown regression function is decomposed into wavelets and a hierarchical Bayesian approach is employed for making inferences on the resulting wavelet coefficients.

description: An efficient neutron detection system with good energy resolution is required to correctly characterize decays of neutron-rich nuclei where $β-$delayed neutron emission is a dominant decay mode. The Neutron dEtector with Xn Tracking (NEXT) has been designed to measure $β$-delayed neutron emitters. By segmenting the detector along the neutron flight path, NEXT reduces the associated uncertainties in neutron time-of-flight measurements, improving energy resolution while maintaining detection efficiency. Detector prototypes are comprised of optically separated segments of a neutron-gamma discriminating plastic scintillator coupled to position-sensitive photomultiplier tubes. The first performance studies of this detector showed that high intrinsic neutron detection efficiency could be achieved while retaining good energy resolution. The results from the efficiency measurements using neutrons from direct reactions are presented.

GRB 060218: The nature of the optical-UV component
Creators: name: Björnsson, C. -I.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The optical-UV component in GRB 060218 is assumed to be due to optically thick cyclotron emission. The key aspect of this model is the high temperature of the absorbing electrons. The heat input derives from nuclei accelerated in semi-relativistic internal shocks, like in ordinary gamma-ray bursts. Coulomb collisions transfer part of that energy to electrons. Inverse Compton cooling on the X-ray photons leads to electron temperatures around 100 keV. Such a high brightness temperature for the optical-UV emission implies an emitting area roughly equal to that of the thermal X-ray component. This suggests a model in which the radio, optical-UV and thermal X-ray emission are closely related: Although the optical-UV and thermal X-ray emission are two separate spectral components, it is argued that they both come from the photosphere of a quasi-spherical, continuous outflow, whose interaction with the circumstellar medium gives rise to the radio emission. The properties of GRB 060218, as measured in the co-moving frame, are similar to those of ordinary gamma-ray burst; i.e., the main difference is the much lower value of the bulk Lorentz factor in GRB 060218. The cyclotron absorption implies a magnetic field in rough equipartition with the matter energy density in the outflow. Hence, the magnetic field could have a dynamically important role, possibly with a magnetar as the central engine.

description: We demonstrate high-resolution modification of suspended multi-layer graphene sheets by controlled exposure to the focused electron beam of a transmission electron microscope. We show that this technique can be used to realize, on timescales of a few seconds, a variety of features, including nanometer-scale pores, slits, and gaps that are stable and do not evolve over time. Despite the extreme thinness of the suspended graphene sheets, extensive removal of material to produce the desired feature geometries is found to not introduce long-range distortion of the suspended sheet structure.
-55 degrees C to 170 degrees C High Linear Voltage References Circuitry in 0.18ìm Cmos Technology

description: High linear voltage references circuitry are designed and implemented in TSMC 0.18$μ$m CMOS technology. Previous research has proposed the use of MOS transistors operating in the weak inversion region to replace the bipolar devices in conventional PTAT(proportional to absolute temperature) circuits. However such solutions often have linearity problem in high temperature region due to the current leaking devices in modern deep sub micron and nano-scale CMOS technology. The proposed circuit utilized temperature complementation technique on two voltage references, PTAT and IOAT (independent of absolute temperature) references, to enhance the linearity and produce a more stable IOAT voltage reference. Base on the simulation results, the R-squares of both circuitries are better than 0.999 in a considerable wider temperature range from -55 degrees C to 170 degrees C. Thus, a fully integrated temperature sensor with wider temperature range is designed and easily to integrate to modern system-on-chip designs with minimal efforts.

A full parametrization of the $9\times 9$ active-sterile flavor mixing matrix in the inverse or linear seesaw scenario of massive neutrinos
Creators: name: Han, He-chong

Year: 2021

subject: FOS: Physical sciences

description: The inverse and linear seesaw scenarios are two typical extensions of the canonical seesaw mechanism, which contain much more sterile degrees of freedom but can naturally explain the smallness of three active neutrino masses at a sufficiently low energy scale (e.g., the TeV scale). To fully describe the mixing among three active neutrinos, three sterile neutrinos and three extra gauge-singlet neutral fermions in either of these two seesaw paradigms, we present the {\it first} full parametrization of the $9\times 9$ flavor mixing matrix in terms of 36 rotation angles and 36 CP-violating phases. The exact inverse and linear seesaw formulas are derived, respectively; and possible deviations of the $3\times 3$ active neutrino mixing matrix from its unitary limit are discussed by calculating the effective Jarlskog invariants and unitarity nonagons.

A study of the social and economic conditions of child in care families
Creators: name: Chan, Albert Wai-Yip
Publisher: name: University of British Columbia
Year: 2010

description: This study examined the social and economic conditions of child in care families in Regions 1 and 15 of the Ministry of Human Resources, Vancouver, British Columbia. The relationships between the social and economic conditions of the families and the legal status of the children in care were analyzed. In addition, the relationships between the changes of the social and economic conditions of the families and the changes of the legal status of the children in care were also examined. A total of sixty child in care cases were used, with twenty cases from each of the legal status groups - from temporary custody to discharge, temporary custody order extended, and from temporary custody order to permanent custody order. The findings illustrated that the vast majority of the child in care families were from low social and economic class. Among the families of the three legal status groups, families with extreme low social and economic position were more vulnerable to permanent removal of their children. In contrast, families to which the children were returned had better social and economic conditions than the temporary custody extended and permanent ward families.
