description: As undoubtedly heard, being a single parent was already a handful. Then what more if that single parent who is raising her child is a part of the LGBTQ+ community? Many people will probably judge and give them a look of disgust for being a parent and, society might be shocked and perplexed on why homosexual parents have a kid. There is a high tendency that these homosexual parents will be doubted in parenting their child. An extensive amount of the bigger world tells us that an average family consists of a straight mother and father. However, these LGBTQ+ families are also considered brave, tough, and independent warriors for raising their children in this critical society. Those flexible characteristics of homosexual parents can be a rich and robust foundation for raising a child. On the other hand, it can also bring additional difficulties and hindrances than to those heterosexual single parent, especially in our society who thinks that this kind of situation does not fit in our norms. This study aims to describe the lived experiences of the lesbian parents. Moreover, the implications of the study were discussed, and recommendations were suggested.

description: The solving of least square systems is a useful operation in neurocomputational modeling of learning, pattern matching, and pattern recognition. In these last two cases, the solution must be obtained on-line, thus the time required to solve a system in a plausible neural architecture is critical. This paper presents a recurrent network of Sigma-Pi neurons, whose solving time increases at most like the logarithm of the system size, and of its condition number, which provides plausible computation times for biological systems.

description: This paper presents a state estimation approach for an uncertain linear equation with a non-invertible operator in Hilbert space. The approach addresses linear equations with uncertain deterministic input and noise in the measurements, which belong to a given convex closed bounded set. A new notion of a minimax observable subspace is introduced. By means of the presented approach, new equations describing the dynamics of a minimax recursive estimator for discrete-time non-causal differential-algebraic equations (DAEs) are presented. For the case of regular DAEs it is proved that the estimator's equation coincides with the equation describing the seminal Kalman filter. The properties of the estimator are illustrated by a numerical example.

Disownment of Indo-Canadian women
Creators: name: Jheeta, Swinder Kaur
Publisher: name: University of British Columbia
Year: 2010

description: This study explores the psychological and social aspects of the experience of being disowned. Disownment can arise at two levels. At the intrapersonal level disownment is characterized by: the repression of emotions, needs, and aspects of one's personality. At the interpersonal level, disownment involves the complete break in social, emotional, economic, familial support and community relations. This paper examines the relationship between the two. Ten Indo-Canadian women who had experienced an aspect of disownment were interviewed. Results revealed that a variety of factors can precipitate this stressful event. How these women cope with the experience was determined by factors which either facilitated or hindered the adjustment process. From the analysis of the data, disownment not only resulted as a consequence of a life transition but it also emerged as a transitional process. The disownment model is presented to provide a framework for understanding this underlying process. The three stage model of disownment describes the: 1) anticipation of shift, 2) adjustment and 3) re-integration. Implications of the model for counseling and research are also discussed.

description: We consider the realization of a quantum computer in a chain of nuclear spins coupled by an Ising interaction. Quantum algorithms can be performed with the help of appropriate radio-frequency pulses. In addition to the standard nearest-neighbor Ising coupling, we also allow for a second neighbor coupling. It is shown, how to apply the 2πk method in this more general setting, where the additional coupling eventually allows to save a few pulses. We illustrate our results with two numerical simulations: the Shor prime factorization of the number 4 and the teleportation of a qubit along a chain of 3 qubits. In both cases, the optimal Rabi frequency (to suppress non-resonant effects) depends primarily on the strength of the second neighbor interaction.

description: Quantum key distribution (QKD) network has recently attracted growing attentions. Due to the special characteristics of quantum information, to build a full-connectivity QKD network without trusted relays is a stimulating challenge. In this letter, we report on the first realization of QKD network without trusted relays which covers metropolis in the commercial backbone optical fiber networks. The star topology four-user QKD network automatically addresses the quantum signal with a quantum router (QR) and every user in the network can receive and distribute quantum keys to any others simultaneously. The longest and the shortest length of fibers between two geographically separated nodes are 42.6km and 32km respectively, and the maximum average quantum bit error rate (QBER) is below 8%. This result opens a new possibility for the use of QKD into existing network.

description: Observations in the lowest MWA band between $75-100$ MHz have the potential to constrain the distribution of neutral hydrogen in the intergalactic medium at redshift $\sim 13-17$. Using 15 hours of MWA data, we analyse systematics in this band such as radio-frequency interference (RFI), ionospheric and wide field effects. By updating the position of point sources, we mitigate the direction independent calibration error due to ionospheric offsets. Our calibration strategy is optimized for the lowest frequency bands by reducing the number of direction dependent calibrators and taking into account radio sources within a wider field of view. We remove data polluted by systematics based on the RFI occupancy and ionospheric conditions, finally selecting 5.5 hours of the cleanest data. Using these data, we obtain two sigma upper limits on the 21 cm power spectrum in the range of $0.1\lessapprox k \lessapprox 1 ~\rm ~h~Mpc^{-1}$ and at $z$=14.2, 15.2 and 16.5, with the lowest limit being $6.3\times 10^6 ~\rm mK^2$ at $\rm k=0.14 \rm ~h~Mpc^{-1}$ and at $z=15.2$ with a possibility of a few \% of signal loss due to direction independent calibration.

Fast Computation of Moore-Penrose Inverse Matrices

description: Many neural learning algorithms require to solve large least square systems in order to obtain synaptic weights. Moore-Penrose inverse matrices allow for solving such systems, even with rank deficiency, and they provide minimum-norm vectors of synaptic weights, which contribute to the regularization of the input-output mapping. It is thus of interest to develop fast and accurate algorithms for computing Moore-Penrose inverse matrices. In this paper, an algorithm based on a full rank Cholesky factorization is proposed. The resulting pseudoinverse matrices are similar to those provided by other algorithms. However the computation time is substantially shorter, particularly for large systems.

description: We are in the middle of a remarkable paradigm shift in particle physics, a shift of opinion that occurred so slowly that some even try to deny that they changed their minds at all. It concerns a very basic question: can we expect to derive the laws of particle physics from a fundamental theory? The Standard Model of particle physics as well as the 1984 string theory revolution provided ample food for thought about this. The reason this was ignored for so long can be traced back to an old fallacy: a misguided idea about our own importance.

description: A dynamical system on the total space of the fibre bundle of second order accelerations, $T^2M$, is defined as a third order vector field $S$ on $T^2M$, called semispray, which is mapped by the second order tangent structure into one of the Liouville vector field. For a regular Lagrangian of second order we prove that this semispray is uniquely determined by two associated Cartan-Poincaré one-forms. To study the geometry of this semispray we construct a nonlinear connection, which is a Lagrangian subbundle for the presymplectic structure. Using this semispray and the associated nonlinear connection we define covariant derivatives of first and second order. With respect to this, the second order dynamical derivative of the Lagrangian metric tensor vanishes.

description: A set of grating couplers that convert plane waves into odd pairs of plasmons supported by extremely thin layers of doped indium tin oxide is designed. The inverse design approach is implemented to improve the efficiency of ordinary periodical couplers significantly. The optimization code based on the gradient descent method and direct Maxwell solver is designed in Matlab. Three models with different optimization levels are compared and discussed. The results of calculations are prepared for subsequent experimental verification. Considered odd plasmonic pairs represent an example of high quality modes tunable using a field effect. They are potentially applicable for the implementation in various active electro-optical devices and lead the way to fully semiconductor based plasmonics.

description: We have searched for nearby dwarf galaxies in 27 northern groups with characteristic distances 8-15 Mpc based on the Second Palomar Sky Survey prints. In a total area of about 2000 square degrees, we have found 90 low-surface-brightness objects, more than 60% of which are absent from known catalogs and lists. We have classified most of these objects (~80%) as irregular dwarf systems. The first 21-cm line observations of the new objects with the 100-m Effelsberg radio telescope showed that the typical linear diameters (1-2 kpc), internal motions (30 km/s), and hydrogen masses (~2*10^7M_sun) galaxies correspond to those expected for the dwarf population of nearby groups.

MIG Median Detectors with Manifold Filter

Publisher: name: arXiv

Subjects: subject: Signal Processing (eess.SP)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: In this paper, we propose a class of median-based matrix information geometry (MIG) detectors with a manifold filter and apply them to signal detection in nonhomogeneous environments. As customary, the sample data is assumed to be modeled as Hermitian positive-definite (HPD) matrices, and the geometric median of a set of HPD matrices is interpreted as an estimate of the clutter covariance matrix (CCM). Then, the problem of signal detection can be reformulated as discriminating two points on the manifold of HPD matrices, one of which is the HPD matrix in the cell under test while the other represents the CCM. By manifold filter, we map a set of HPD matrices to another set of HPD matrices by weighting them, that consequently improves the discriminative power by reducing the intra-class distances while increasing the inter-class distances. Three MIG median detectors are designed by resorting to three geometric measures on the matrix manifold, and the corresponding geometric medians are shown to be robust to outliers. Numerical simulations show the advantage of the proposed MIG median detectors in comparison with their state-of-the-art counterparts as well as the conventional detectors in nonhomogeneous environments.

Self-esteem components in eating disordered women : body-image disturbance, body dissatisfaction, and cultural and individual body shape ideals
Creators: name: McLagan, Beverley May
Publisher: name: University of British Columbia
Year: 2010

description: This study examined the differences between eating disordered and non-eating disordered women on self-deficits, specifically self-esteem, body-image disturbance, and body dissatisfaction. In addition, the existence of a cultural and individual ideal body shape was investigated. It was expected that eating disordered women, compared to non-eating disordered women would exhibit lower self-esteem, higher body dissatisfaction and a greater degree of body overestimation (as measured by the waist). Furthermore, it was expected that eating disordered women would choose a thinner cultural and individual ideal shape than the non-eating disordered women. The subjects were 82 females aged 19 to 40 years. The eating disordered group was recruited from a local support group and subjects met either the DSM-III (1980) criteria for anorexia nervosa, or Russell's (1979) criteria for bulimia nervosa. None of these subjects were hospitalized at the time of testing. Non-eating disordered subjects were nursing students recruited from a local college. The Eating Attitudes Test was administered to these subjects as a screening device to ensure that no subjects were included who had a mild eating disorder. All subjects completed a test package: The Eating Attitudes Test; The Adult Self-Perception Profile; The Eating Disorder Inventory; and a demographic sheet. At a second interview, subjects completed a body-image estimation procedure (Askevold, 1975), the cultural and individual ideal questions (Perceived Body Image Scale, Manley & LePage, 1986), and were weighed and measured for height. A one-way multivariate analysis of variance was computed for measures of self-esteem, body dissatisfaction and body-image disturbance, examining differences between the two groups. Significant differences were found for self-esteem and body dissatisfaction (p < .001), with body-image disturbance approaching significance (p < .06). An investigation of the means revealed that eating.disordered women showed less self-worth, more ineffectiveness and experienced greater body dissatisfaction, than did non-eating disordered women. While body-image disturbance was present in both groups, the eating disordered group showed a slightly greater tendency to overestimate their waist area than did the non-eating disordered group. A Chi square analysis computed for the cultural and individual ideals revealed the eating disordered group chose a significantly thinner cultural ideal shape (p < .05) and individual ideal shape (p < .001) than the non-eating disordered group. Both groups chose a very narrow range of acceptable female shapes to represent the cultural and individual ideal body shapes. Implications for these results and suggestions for future research are discussed.

description: No abstracts are to be cited without prior reference to the author.By combining data collected in 1990-1996 on harp seal Phoca groenlandilica diet compositions from various areas arid seasons in the Barents Sea, with information on the energy density of various prey species, it was possible, under certain assumptions, to estimate the total consumption of various prey items required by the harp seals in order to cover their energy demands. All diet composition data were based on reconstructed prey biomass, and it was adjusted for differences in digestability of crustaceans and fish. The number of seals belonging to different age and sex groups was calculated, and then their rricinthly food requirements were modelled.

description: A large fraction of observed protoplanetary disks in nearby Star-Forming Regions (SFRs) are fainter than expected in CO isotopologue emission. Disks not detected in 13CO line emission are also faint and often unresolved in the continuum emission at an angular resolution of around 0.2 arcseconds. Focusing on the Lupus SFR, the aim of this work is to investigate whether the population of CO-faint disks comprises radially extended and low mass disks - as commonly assumed so far - or if it is of intrinsically radially compact disks, an interpretation that we propose in this paper. The latter scenario was already proposed for individual sources or small samples of disks, while this work targets a large population of disks in a single SFR for which statistical arguments can be made. A new grid of physical-chemical models of compact disks has been run with DALI in order to cover a region of the parameter space that had not been explored before with this code. Such models have been compared with 12CO and 13CO ALMA observations of faint disks in Lupus. Disks that are not detected in 13CO emission and with faint or undetected 12CO emission are consistent with compact disk models. For radially compact disk, the emission of CO isotopologues is mostly optically thick and it scales with the surface area: i.e., it is fainter for smaller objects. The fraction of compact disks is potentially between roughly 50% and 60% of the entire Lupus sample. Deeper observations of 12CO and 13CO at a moderate angular resolution will allow us to distinguish whether faint disks are intrinsically compact, or if they are extended but faint, without the need of resolving them. If the fainter end of the disk population observed by ALMA disk surveys is consistent with such objects being very compact, this will either create a tension with viscous spreading or require MHD winds or external processes to truncate the disks.

description: Ferroelectric field-effect transistors (Fe-FETs) with ferroelectric hafnium oxide (FE HfO2) as gate insulator are being extensively explored as a promising device candidate for three-dimensional (3D) NAND memory application. FE HfO2 exhibits long retention over 10 years, high endurance over 1012 cycles, high speed with sub-ns polarization switching, and high remnant polarization of 10-30 μC/cm2. However, the performance of Fe-FETs is known to be much worse than FE HfO2 capacitors, which is not completely understood. In this work, we developed a comprehensive Fe-FET model based on a charge balance framework. The role of charge balance and the impact of leakage-assist-switching mechanism on the memory characteristics of Fe-FETs with M/FE/DE/S (Metal/Ferroelectric/Dielectric/Semiconductor) gate stack is studied. It is found that the FE/DE interface and DE layer instead of FE layer is critical to determine the memory characteristics of Fe-FETs, and experimental Fe-FETs can be well explained by this model, where the discrepancy between FE capacitors and Fe-FETs are successfully understood.

For J2 = 0 we find a spin-density-wave phase for all positive values of the Hubbard interaction U and the Heisenberg exchange J1. A frustrating spin exchange J2 induces a bond-order-wave phase. For some values of J1, J2 and U, we observe a spin-gapped metallic Luther-Emery phase.

description: We investigate the ground state of the one-dimensional fermionic system enclosed in a hard-wall trap with attractive contact p-wave interactions. Based on the Bethe ansatz method, the explicit wave function is derived by numerically solving the Bethe ansatz equations for the full physical regimes ($-\infty \leq c_F\leq 0$). With the exact wave function some quantities which are important in many-body physics are obtained, including the one-body density matrix and the momentum distribution of the ground state for finite system. It is shown that the shell structure of the density profiles disappears with the increase of the interaction and in the fermionic Tonks-Girardeau (FTG) limit the density distribution shows the same behavior as that of an ideal Bose gas. However the one-body density matrix and the momentum distribution exhibit completely different structures compared with their bosonic counterparts.

description: We study an adaptation to the logarithmic case of the Kobayashi-Eisenman pseudo-volume form, or rather an adaptation of its variant defined by Claire Voisin, for which she replaces holomorphic maps by holomorphic K-correspondences. We define an intrinsic logarithmic pseudo-volume form Φ_{X,D} for every pair (X,D) consisting of a complex manifold X and a normal crossing Weil divisor, the positive part of which is reduced. We then prove that Φ_{X,D} is generically non-degenerate when X is projective and K_X+D is ample. This result is analogous to the classical Kobayashi-Ochiai theorem. We also show the vanishing of Φ_{X,D} for a large class of log-K-trivial pairs, which is an important step in the direction of the Kobayashi conjecture about infinitesimal measure hyperbolicity in the logarithmic case.

description: Search trees are commonly used to implement access operations to a set of stored keys. If this set is static and the probabilities of membership queries are known in advance, then one can precompute an optimal search tree, namely one that minimizes the expected access cost. For a non-key query, a search tree can determine its approximate location by returning the inter-key interval containing the query. This is in contrast to other dictionary data structures, like hash tables, that only report a failed search. We address the question "what is the additional cost of determining approximate locations for non-key queries"? We prove that for two-way comparison trees this additional cost is at most 1. Our proof is based on a novel probabilistic argument that involves converting a search tree that does not identify non-key queries into a random tree that does.

description: We measure the non-axisymmetry in the luminosity distribution in the central few kpc of a sample of advanced mergers of galaxies, by analyzing their 2MASS images. All mergers show a high central asymmetry: the centres of isophotes show a striking sloshing pattern with a spatial variation of upto 30 % within the central 1 kpc; and the Fourier amplitude for lopsidedness (m=1) shows high values upto 0.2 within the central 5 kpc. The central asymmetry is estimated to be long-lived, lasting for ~ a few Gyr or ~ 100 local dynamical timescales. This will significantly affect the dynamical evolution of this region, by helping fuel the central active galactic nucleus, and also by causing the secular growth of the bulge driven by lopsidedness.

description: No abstracts are to be cited without prior reference to the author.Our understanding of the seasonal distribution and migratory behaviour of harp seals is based primarily on surveys of whelping and moulting concentrations, catch data, tag returns and anecdotal observations which may be biased by the location of the observer. To determine the seasonal distribution of harp seals in detail, satellite transmitters were deployed on 22 newly moulted, adult harp seals captured in 1995 (n= l l) and 1996 (n= IO) along the coast of Newfoundland and southern Labrador. Seals were tracked for periods of 22 - 356 days and provided a total of 13,309 transmissions. Locations were obtained on an average of34.6_% (SE=4.7, range 4.3 -90.6%) of the days. Seasonal movements varied greatly among individuals and between years; there were no differences between males and females. Harp seals ranged from the northern Scotian Shelf and Grand Banks of Newfoundland in the spring and winter, north to Baffin Bay, southeastern Greenland and Hudson Strait in the summer. The Grand Banks appeared to be an important wintering area in both years. Much of their time was spent in offshore areas where they are rarely observed using traditional techniques. The occurrence of seals on the southern Grand Banks, Flemish Cap and Scotian Shelf may indicate a southern shift in distribution in recent years. The timing of the annual migrations in 1996 was similar to those reported previously. Both the northward and southward migrations occurred earlier in 1995 than in 1996, but the differences were not significant. TI1is study illustrates the complexity of movements in a wide-ranging pelagic species such as the harp seal.

description: No abstracts are to be cited without prior reference to the author.It is generally reported that polar fish species produce relatively few, large eggs comapred with that of fish species at lower latitudes. However, egg size and fecundity (I. e. the total number of eggs to be spawned) in fish is thought also to be linked to their mode of oviposition.
Hypnosis : an effective intervention for migraine headaches
Creators: name: Munch, Rod J.
Publisher: name: University of British Columbia
Year: 2010

description: The general distribution of the headache worldwide, its widespread occurrence, and its frequency of incidence is well documented. It is a disorder that often goes unreported with pharmaceutical intervention being the most commonly applied remedy. The National Migraine Foundation estimates that 42 million Americans suffer from headaches. Of these 8 to 12 million Americans are afflicted by the migraine headache. This study examined the effectiveness of hypnotherapy as an intervention for migraines. It was a single case holistic study in which a 23 year old female migraineur provided the single unit of analysis. Assessments of self concept; stress; headache frequency, duration, and intensity; and consumption of pharmacological substances were made prior to treatment, during treatment, and following treatment. The therapy consisted of eight sessions over 2 1/2 weeks and consisted of a relaxation induction and guided imagery of control of physiological responses. An audiotape of the hypnotherapy intervention was also used on a dally basis by the client. Results from post therapy and follow-up tests confirmed the treatment was effective. This was maintained at the one and two month follow-ups.

description: A new type of ensemble filter is proposed, which combines an ensemble Kalman filter (EnKF) with the ideas of morphing and registration from image processing. This results in filters suitable for nonlinear problems whose solutions exhibit moving coherent features, such as thin interfaces in wildfire modeling. The ensemble members are represented as the composition of one common state with a spatial transformation, called registration mapping, plus a residual. A fully automatic registration method is used that requires only gridded data, so the features in the model state do not need to be identified by the user. The morphing EnKF operates on a transformed state consisting of the registration mapping and the residual. Essentially, the morphing EnKF uses intermediate states obtained by morphing instead of linear combinations of the states.

description: At any epoch, particle physics must be open to completely unexpected discoveries, and that is reason enough to extend the reach of searches for ultra-high energy (UHE) photons. The observation of a population of photons with energies $E \gtrsim 100$ EeV would for example imply the existence of either a completely new physical phenomena, or particle acceleration mechanisms heretofore never seen or imagined. But as we outline in this Letter of Interest, there are also good arguments for super-heavy dark matter (SHDM) in a parameter range such that it could be discovered via its decays to, in particular, UHE photons. Only ultra-high energy cosmic ray observatories have capabilities to detect UHE photons. We first investigate how current and future observations can probe and constrain SHDM models in important directions, and then outline some of the scenarios that motivate such searches. We also discuss connections between constraints on SHDM and on the parameter values of cosmological models.

Subsetting

description: The Blue Cloud Data Discovery and Access Service (DD&AS) is one of the
components of the Blue-Cloud technical framework. It serves federated
discovery and access to Blue Data Infrastructures (BDIs) for external users
and also interacts with the Blue-Cloud Virtual Research Environment (the
component federating computing platforms and analytical services) for
populating the VRE data pool. Within the framework of the H2020 pilot
Blue-Cloud project, the first operational release of the Blue-Cloud DD&AS
was deployed. This service is federating in total 8 BDIs and with 9 data
services. The implementation of the Blue Cloud DD&AS largely depends on
machine-to-machine interactions between central components of the DD&AS and
web services / APIs as managed and operated by the BDIs. In practice, the
development has been quite challenging as each of the BDIs is offering web
services for discovery and access which are different in functionality and
not always straightforward. In the Blue- Cloud 2026 project it is strived
for further optimisation of the DD&AS, in particular, where possible, by
improving the FAIRness of the services and contents as provided by the
federated BDIs. In addition, it is explored how the overall functionality
of the DD&AS might be expanded. In this Deliverable, first of all, an
overview is given of the current architecture and functionality of the
Blue-Cloud DD&AS to provide good insight in the DD&AS conceptual
principles. Then per BDI an overview is given of their current federation,
followed by an assessment of possible improvements, which should be
undertaken by and/or with each BDI. These analyses and assessment have been
made via a continuous dialogue between MARIS and CNR-IIA as core DD&AS
developers with each of the BDIs and associated technical providers. This
started at the Project Kick-Off meeting, 13–15 February 2023 in Pisa –
Italy, during a dedicated WP2 session, and the first Technical and
Scientific Committee (TSC) meeting, organised on 28-29 March 2023 in
Amsterdam – Netherlands. At these meetings the common principles for
optimisation of the DD&AS were discussed and agreed. Since then, the core
developers have been reviewing the current deployments, supported by email
exchanges with BDIs, where needed. This has been followed by bilateral web
conferences with managers of each of the BDIs between August and October
2023 to discuss findings and ideas. Finally, this has resulted in a series
of proposed improvements for each of the BDIs and the central DD&AS core
service. These will be worked out and taken into development in the coming
period as part of WP2 activities.

description: In this paper we will study the homological properties of various natural modules associated to the Fourier algebra of a locally compact group. In particular, we will focus on the question of identifying when such modules will be projective in the category of operator spaces. We will show that projectivity often implies that the underlying group is discrete and give evidence to show that amenability also plays an important role.
