description: The retention of spatial information in visual short-term memory was assessed by measuring spatial frequency discrimination thresholds with a two-interval forced-choice task varying the time interval between the two gratings to be compared. The memory of spatial frequency information was perfect across 10-sec interstimulus intervals. Presentation of a “memory masker” grating during the interstimulus interval may interfere with short-term memory. This interference depends on the relative spatial frequency of the test and masker gratings, with maximum interference at spatial frequency differences of 1–1.5 octaves and beyond. This range of interference with short-term memory is comparable to the bandwidth of sensory masking or adaptation. A change of the relative orientation of test and masker gratings does not produce interference with spatial frequency discrimination thresholds. These results suggest stimulus-specific interactions at higher-level representations of visual form.
title: Mental health workers' perceptions and perspectives on the right to health and a human rights-based approach to mental health: A case study of the Chitwan District in Nepal
Creators: name: Gunilla Backman, Ingrid
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2018

description: Over the last decade, there have been increasing calls for respecting and integrating human rights into health, including into mental health policies, plans, and programmes. The convergence of mental health and the right to health has implications for health workers, as they are the key translators of policy- and programme-related decisions into practice.
This thesis is a qualitative research study which follows a case-study approach situated in the Programme for Improving Mental Health Care in Nepal. It aims to explore the perceptions and perspectives of health workers in the Chitwan district in Nepal on the use of a human rights-based approach (HRBA) to mental health. The specific objectives are to (1) examine existing evidence on the use of an HRBA to advance health; (2) explore perspectives on the right to health among mental health workers in Nepal; (3) explore health workers’ perceptions of the application of an HRBA to mental health in planning and service provision; and (4) develop a conceptual framework regarding the use of an HRBA to mental health.
The literature review identified some plausible positive evidence on the use of an HRBA to advance health, but also highlighted the very limited quantity and quality of the evidence and the difficulty in determining with certainty the direct influence of an HRBA to health. No studies were identified that explored an HRBA to mental health in low- or middle-income countries. The qualitative research highlighted that participants were aware of human rights, but faced difficulty in understanding their meaning and application, including an HRBA.
An HRBA to health and related plans requires an understanding of both the health system context and involvement of health workers. A conceptual framework was developed of an HRBA to mental health to help guide the application of an HRBA in mental health planning and service provision. Recommendations are provided.

description: True atomic resolution of conductors and insulators is now routinely obtained in vacuum by frequency modulation atomic force microscopy. So far, the imaging parameters (i.e., eigenfrequency, stiffness and oscillation amplitude of the cantilever, frequency shift) which result in optimal spatial resolution for a given cantilever and sample have been found empirically. Here, we calculate the optimal set of parameters from first principles as a function of the tip–sample system. The result shows that the either the acquisition rate or the signal-to-noise ratio could be increased by up to two orders of magnitude by using stiffer cantilevers and smaller amplitudes than are in use today.

description: We consider localised states in a discrete bistable Allen-Cahn equation. This model equation combines bistability and local cell-to-cell coupling in the simplest possible way. The existence of stable localised states is made possible by pinning to the underlying lattice; they do not exist in the equivalent continuum equation. In particular we address the existence of 'isolas': closed curves of solutions in the bifurcation diagram. Isolas appear for some non-periodic boundary conditions in one spatial dimension but seem to appear generically in two dimensions. We point out how features of the bifurcation diagram in 1D help to explain some (unintuitive) features of the bifurcation diagram in 2D.

Sexual identity, minority stress, and the mental health of lesbian, gay, bisexual, and heterosexual Canadians
Creators: name: Pakula, Barbara (Basia) Joanna
Publisher: name: University of British Columbia
Year: 2017

description: Background: Addressing mental health has emerged as a priority in Canada. The mental illness burden is thought to disproportionately affect some subgroups, including those self-identifying as lesbian, gay, and bisexual (LGB). Yet, to date, no reliable population estimates are available to characterize the prevalence of common mental health disorders amongst LGB Canadians. Objectives: (1) Investigate the prevalence and correlates of anxiety, mood, and anxiety-mood disorders, heavy drinking, and co-occurring anxiety or mood disorders and heavy drinking among Canadians self-identified as LGB. (2) Examine whether life stress mediates and sense of community belonging moderates the relationship between sexual identity and the study outcomes. (3) Assess the heterogeneity in the prevalence of the study outcomes by sexual identity at intersections with other social positions (i.e., sex, age, income, education, and racialized minority status). Methods: Pooled data from the 2007–2012 cycles of the Canadian Community Health Survey (N = 222,548) were used to obtain a multi-year sample of Canadians aged 18–59 years, who self-identified as LGB or heterosexual. Analyses included a series of logistic regression models, stratified binary mediation models, and models with multiple interaction terms. Bootstrapping was used to obtain standard errors and confidence intervals. Results: LGB-identified Canadians reported substantially greater odds of mental health disorders compared with heterosexual peers: the odds of anxiety, mood, anxiety-mood, and co-occurring disorders were double for gay/lesbian-identified respondents, and more than triple for bisexual-identified respondents. Perceived life stress partially mediated the effects of sexual identity on the outcomes, and the greatest odds were observed for bisexual respondents. Combinations of disadvantaged positions of reporting a gay/lesbian or bisexual identity (vs. heterosexual) with vulnerabilities related to income, age and sex were found to have multiplicative effects on the rates of mood and anxiety disorders. Discussion: The results provide the first national estimates for common mental health disorders reported by LGB-identified Canadians. They suggest that universal interventions (thought to be applicable to all sexual identities) may ameliorate some, but not substantially diminish all, observed mental health disparities. Informed by these results, future interventions tailored to meet the specific needs of LGB people, particularly bisexual-identified, may hold promise.
A simplified but intuitive analytical model for intermittent-contact-mode force microscopy based on Hertzian mechanics

Subjects: subject: Atomic force microscopy; Intermittent contact; Tapping mode
subject: 530 Physik

description: The forces acting on the substrate in intermittent-contact-mode (IC mode, tapping mode) atomic force microscopy are not accessible to a direct measurement. For an estimation of these forces, a simple analytical model is developed by considering only the shift of the cantilever resonance frequency caused by Hertzian (contact) forces. Based on the relationship between frequency shift and tip–sample force for large-amplitude frequency-modulation atomic force microscopy, amplitude and phase versus distance curves are calculated for the intermittent contact mode, and the forces on the substrate are calculated. The results show a qualitative agreement with numerical calculations, yielding typical maximal forces of 50–150 nN. When working above the unperturbed resonance, forces are found to be significantly larger than below the resonance.

Spatial Frequency Discrimination of Band-limited Periodic Targets: Effects of Stimulus Contrast, Bandwidth and Retinal Eccentricity

Subjects: subject: Spatial frequency discrimination; Contrast; Bandwidth; Retinal eccentricity
subject: 150 Psychologie

description: Two experiments were conducted to explore the ability of human observers to discriminate the spatial frequency of briefly-presented, Gaussian-truncated sinewave gratings. In the first experiment, the influence of stimulus contrast and stimulus bandwidth on discrimination thresholds was measured after removing any position cues by randomizing the spatial phase of the gratings for each presentation. In a second experiment, the influence of retinal eccentricity on discrimination thresholds was explored for Gaussian-truncated gratings of constant spatial frequency bandwidth (0.5 octave) and suprathreshold contrast value (5 × detection threshold). The spatial frequency of the reference gratings varied from 1 to 8c/deg. The gratings were positioned centered at the fixation point or 1–20 deg eccentric of the point of fixation along the horizontal meridian. Two observers responded in a two-interval forced-choice paradigm, which of two gratings had a higher spatial frequency. A difference frequency was randomly added to or subtracted from the spatial frequency of either the first or second grating. Using a maximum-likelihood algorithm, the spatial-frequency discrimination threshold was computed from 40 trials, at which the observer responded with 75% accuracy. The results indicate that discrimination thresholds increase with (1) decreasing stimulus contrast, (2) increasing stimulus bandwidth, and (3) increasing retinal eccentricity. It is shown that spatial-frequency discrimination thresholds are only independent of contrast for narrow bandwidth stimuli having a contrast > 0.02. The eccentricity-dependent increase in discrimination thresholds varies with reference spatial frequency: with increasing retinal eccentricityΔf/f increases gradually for low spatial frequencies but rapidly for high spatial frequencies.
Preferential Belief Change Using Generalized Epistemic Entrenchment

Year: 1992
Subjects: subject: Belief revision, epistemic entrenchment, theory change
subject: 100 Philosophie

description: A sentence A is epistemically less entrenched in a belief state K than a sentence B if and only if a person in belief state K who is forced to give up either A or B will give up A and hold on to B. This is the fundamental idea of epistemic entrenchment as introduced by Gärdenfors (1988) and elaborated by Gärdenfors and Makinson (1988). Another distinguishing feature of relations of epistemic entrenchment is that they permit particularly simple and elegant construction recipes for minimal changes of belief states. These relations, however, are required to satisfy rather demanding conditions. In the present paper we liberalize the concept of epistemic entrenchment by removing connectivity, minimality and maximality conditions. Correspondingly, we achieve a liberalization of the concept of rational belief change that does no longer presuppose the postulates of success and rational monotony. We show that the central results of Gärdenfors and Makinson are preserved in our more flexible setting. Moreover, the generalized concept of epistemic entrenchment turns out to be applicable also to relational and iterated belief changes.

description: By requiring unambiguous symmetric quantization leading to the Dirac equation in a curved space, we obtain a special representation of the spin connections in terms of the Dirac gamma matrices and their space-time derivatives. We also require that squaring the equation give the Klein-Gordon equation in a curved space in its canonical from (without spinor components coupling and with no first order derivatives). These requirements result in matrix operator algebra for the Dirac gamma matrices that involves a universal curvature constant. We obtain exact solutions of the Dirac and Klein-Gordon equations in 1+1 space-time for a given static metric.

description: This article examines the (lack of) coherence between the legislative fields that govern the life cycle of materials and products and thus are relevant to the transition towards a circular economy in the EU: EU chemicals, product and waste legislation. After examining the notion of coherence in law, it provides insight into the role of coherence in EU chemicals, product and waste legislation in light of the transition towards a circular economy. The article examines the (possible) issues that exist at the interface between these three legislative fields by reviewing literature and EU policy documents and looks into the relation between these issues and the (lack of) coherence between EU chemicals, product and waste legislation. It is argued that, when looked at in light of the transition towards a circular economy, several issues might be related to a lack of coherence. Nonetheless, the aspiration to achieve full coherence should be looked at critically.

description: Interactions between size and orientation-specific mechanisms in the human visual system were investigated using a sequential adaptation technique. Subjects adapted to a vertical, 4c/deg high-contrast (0.7) sinewave grating that was interleaved at a rate of 0.5 Hz with another adapting grating differing either in (1) spatial frequency or (2) orientation. Before and after adaptation contrast thresholds were measured for a vertical 4c/deg sinewave test grating. The resultant elevation in contrast threshold was plotted as a function of the (1) spatial frequency or (2) orientation differences between the first and second adapting gratings. Maximum threshold elevation was found when both adapting gratings shared the same spatial frequency and orientation. Minimum elevations were found when the second grating's spatial frequency or orientation differed by approx. 1.5 octaves or 45 deg, respectively. Beyond these values threshold elevations reapproached the baseline value measured in a control condition, where the 4.0 c/deg adapting grating was interleaved with a blank. The minimum threshold elevations were 0.2–0.3 log units below the baseline level. The results suggest the existence of inhibitory interactions between neural mechanisms tuned to the size and orientation of retinal images.

This method involves a stochastic process formed from the stochastic energy estimates from Monte Carlo that can be averaged to find precise structural minima while using inexpensive calculations with moderate statistical uncertainty. We demonstrate the applicability of the algorithm by minimizing the energy of the H2O-OH- complex and showing that the structural minima from quantum Monte Carlo calculations affect the qualitative behavior of the potential energy surface substantially.

description: This article examines the effectiveness of various language teaching methods in enhancing the speaking skills of art students. While art students possess unique creative strengths, their linguistic expression can be hindered by a disconnect between visual and verbal communication. The analysis explores the benefits and limitations of traditional methods like the Direct Method and Traditional Method, alongside more contemporary approaches such as Scaffolding, Communicative Language Teaching (CLT), Content and Language Integrated Learning (CLIL), and innovative techniques like Total Physical Response (TPR). The article emphasizes the need for a multi-faceted approach that leverages artistic strengths and promotes authentic communication.

description: Entanglement plays a crucial role in quantum information protocols, thus the dynamical behavior of entangled states is of a great importance. In this paper we suggest a useful scheme that permits a direct measure of entanglement in a two-qubit cavity system. It is realized in the cavity-QED technology utilizing atoms as fying qubits. To quantify entanglement we use the concurrence. We derive the conditions, which assure that the state remains entangled in spite of the interaction with the reservoir. The phenomenon of sudden death entanglement (ESD) in a bipartite system subjected to squeezed vacuum reservoir is examined. We show that the sudden death time of the entangled states depends on the initial preparation of the entangled state and the parameters of the squeezed vacuum reservoir.

description: Chimeric Antigen Receptor T-cell therapy, commonly known as CAR T-cell therapy, stands at the forefront of immunotherapy by transforming a patient’s own immune cells into powerful cancer fighters. This innovative treatment involves extracting T-cells, which are vital immune system components, from a patient’s blood, modifying them genetically to detect cancer specific markers, and returning them to the patient’s body to attack malignant cells. Unlike broad acting treatments like chemotherapy, CAR T-cell therapy zeroes in on cancer with precision, amplifying the body’s natural defenses through advanced engineering.

Effect of Contrast and Adaptation on the Perception of the Direction and Speed of Drifting Gratings

Subjects: subject: Adaptation; Motion perception; Direction discrimination; Speed discrimination
subject: 150 Psychologie

description: Three experiments were conducted to analyse the effect of contrast and adaptation state on the ability of human observers to discriminate the motion of drifting gratings. In the first experiment, subjects judged the direction of briefly presented gratings, which slowly drifted leftward or rightward. The test gratings were enveloped in space by a raised cosine function and in time by a Gaussian. The centre of the spatial envelope was either 2 deg left or right of the fixation point. An adaptive staircase procedure was used to find the velocities, at which the observer judged the motion direction in 75% of the presentations as leftwards or rightwards, respectively. In the second experiment, subjects judged the relative speed of two simultaneously presented gratings. Stimulus contrast was varied in both experiments from 0.01 to 0.32. Discrimination threshold vs contrast functions were measured before and after adaptation to a high-contrast (0.4) grating drifting at rates between 2 and 32 Hz. In a third experiment, subjects matched, before and after adaptation, the relative speed of a test stimulus, which had a constant contrast (0.04 or 0.08) and a variable speed, to that of a reference stimulus having a variable contrast but a constant speed. The results indicate that, before adaptation, direction and speed discrimination thresholds are independent of test contrast, except when test contrast approaches the detection threshold level. Adaptation to a drifting grating increases the lower threshold of motion (LTM) and the speed discrimination threshold (ΔV/V) for low test contrasts. In addition, the point of subjective stationarity (PSS) shifts towards the adapted direction and this shift is more pronounced for low test contrasts. The perceived speed of a drifting grating increases with increasing contrast level. Adaptation to a drifting grating shifts the perceived speed vs log contrast function downwards and to the right (toward higher contrast levels) and this shift is greatest for adaptation frequencies between 8 and 16 Hz. We further explored the effects of adaptation contrast (0.04, 0.4 and 0.9) and adaptation drift direction (iso- or contra-directional) on the perceived speed versus contrast function. The effect of adaptation is greatest for iso-directional drift and increases with increasing adaptation contrast. The results are discussed in terms of a contrast gain control model of adaptation.

description: Sparse coding or sparse dictionary learning has been widely used to recover underlying structure in many kinds of natural data. Here, we provide conditions guaranteeing when this recovery is universal; that is, when sparse codes and dictionaries are unique (up to natural symmetries). Our main tool is a useful lemma in combinatorial matrix theory that allows us to derive bounds on the sample sizes guaranteeing such uniqueness under various assumptions for how training data are generated. Whenever the conditions to one of our theorems are met, any sparsity-constrained learning algorithm that succeeds in reconstructing the data recovers the original sparse codes and dictionary. We also discuss potential applications to neuroscience and data analysis.

Surface based fluid animation using integral equations : simulation and compression
Creators: name: Keeler, Todd
Publisher: name: University of British Columbia
Year: 2017

description: This dissertation looks at exploiting the mathematics of vorticity dynamics and potential flow using integral equations to reformulate critical parts of fully dynamic fluid animation methods into surface based problems. These reformulations enable more efficient calculation and data-structures due to the reduction of the simulation domain to the two dimensional fluid surface, rather than its volume. We also introduce a surface compression and real-time playback method for continuous time-dependent iso-surfaces. This compression method further increases the impact of our highly efficient surface-based simulation methods.

description: This paper aims to answer the following question: Given an adjunction between two categories, how is Quillen (co)homology in one category related to that in the other? We identify the induced comparison diagram, giving necessary and sufficient conditions for it to arise, and describe the various comparison maps. Examples are given. Along the way, we clarify some categorical assumptions underlying Quillen (co)homology: cocomplete categories with a set of small projective generators provide a convenient setup.

description: This paper dwells upon formal models of changes of beliefs, or theories, which are expressed in languages containing a binary conditional connective. After defining the basic concept of a (non-trivial) belief revision model. I present a simple proof of Gärdenfors''s (1986) triviality theorem. I claim that on a proper understanding of this theorem we must give up the thesis that consistent revisions (lsquoadditionsrsquo) are to be equated with logical expansions. If negated or lsquomightrsquo conditionals are interpreted on the basis of lsquoautoepistemic omnisciencersquo, or if autoepistemic modalities (Moore) are admitted, even more severe triviality results ensue. It is argued that additions cannot be philosophically construed as lsquoparasiticrsquo (Levi) on expansions. In conclusion I outline somed logical consequences of the fact that we must not expect lsquomonotonicrsquo revisions in languages including conditionals.

description: We find that the Hodge conjecture is an overdetermined system rather than an underdetermined system, thereby becoming homogenous and leading to overfitting. A product of normal spaces need not be normal thereby initiating and reinforcing the conjecture. A norm should be found through regularization. We find the Magic Star polygon to be a satisfying norm. The Torelli theorem also gives deep and technical proof. Analysis can be seen through a multiple regression technique. Automorphism is not obtainable with a contradiction in the trivial and integral.

description: Background: The prevalence of hypertension in children and adolescents is rising, with 13% having elevated blood pressure and 5% having hypertension. Sex differences play a role in cardiovascular diseases in adults but are not well defined in youth. The objective of this study is to identify sex differences in obesity-mediated cardiometabolic risk factors in adolescents. Methods: This is a pilot study of n=82 youth with obesity recruited from a High BMI Clinic. Clinical data and blood samples were collected at a single time point. Serum sterols were quantified via LC-MS/MS. Number of cardiometabolic risk factors were evaluated. Data are mean +/- standard deviation with analysis via t-tests. Results: Mean BMI was 34.8 in males and 35.8 kg/m2 in females. Diastolic blood pressure (DBP) was significantly higher in females compared to males ((69.4 +/- 8.9 versus 65.3 +/- 6.3 mmHG; P <0.05). It was statistically significant that more females
experienced elevated BP compared to males (p<0.05). There was a significant
interaction between sex and cortisol (p=0.023) for DBP.
Conclusions: There are sex differences in the relationship between plasma cortisol and
DBP in youth with obesity. Modulation of the cortisol pathway may be part of the
mechanism of obesity-associated hypertension in females.

description: It is well known that the bivariate polynomial interpolation problem at domain points of a triangle is correct. Thus the corresponding interpolation matrix $M$ is nonsingular. L.L. Schumaker stated the conjecture, that the determinant of $M$ is positive. Furthermore, all its principal minors are conjectured to be positive, too. This result would solve the constrained interpolation problem. In this paper, the basic conjecture for the matrix $M$, the conjecture on minors of polynomials for degree <=17 and for some particular configurations of domain points are confirmed.
Electroluminescence from Plasmonic Excitations in a Scanning Tunnelling Microscope

description: Die elektromagnetische Kopplung von Ladungsträgern in der Spitze eines Rastertunnelmikroskops and einer leitfähigen Probe führt zu einer plasmonischen Resonanz, die experimentell über ihren strahlenden Zerfall im optischen bis nah-infraroten Bereich zugänglich ist. Aufgrund der Verstärkung des elektrischen Feldes unmittelbar am Spitzenapex ist der optisch aktive Bereich dabei auf Abmessungen weit unterhalb der Wellenlänge des Lichts beschränkt, wobei der elektrisch stimulierte Bereich aufgrund der extremen Lokalisierung des Tunnelstroms noch kleiner ist. Dank der Möglichkeit, die Spitze auf Pikometer-Skala frei zu positionieren, eröffnet dies die einzigartige Möglichkeit, die plasmonische Kavität und ihre Resonanz sowohl hinsichtlich des Spitzen-Proben-Abstandes als auch hinsichtlich der involvierten Materialien und deren Geometrie abzustimmen, wenn die Probe lateral inhomogen ist.
Diese Arbeit stellt die Gestaltung und Inbetriebnahme eines neuen Tieftemperatur-Rastertunnelmikroskops vor, welches mit einer komfortablen und effizienten Lichtsammel-Optik ausgerüstet ist. Die Integration der Spitze und eines Sammelspiegels in ein einziges, mikroskopisches Bauteil ermöglicht den einfachen in-situ Wechsel von Spitze und Probe, und umgeht viele Herausforderungen, auf die andere Experimente in der Literatur bislang gestoßen sind. Testmessungen im Zuge der Inbetriebnahme demonstrieren die Fähigkeit des neuen Instruments, Langzeit-Messungen in nie dagewesenem Ausmaß durchzuführen, und reproduzieren bekannte Effekte aus der Literatur im Detail. Überdies wird in dieser Arbeit auch zum ersten Mal Plasmon-vermittelte Lichtemission von einer wohldefinierten, hetero-epitaktisch gewachsenen Oberfläche bestehend aus zwei verschiedenen Metallen vorgestellt, nämlich Kobalt-Nanoinseln auf einer Kupfer (111) Oberfläche. Dabei zeigt die Lichtemission von unterschiedlich terminierten Teilen der Oberfläche einen signifikanten Intensitätskontrast, der auf die Energie-Abhängigkeit des zugehörigen inelastischen Tunnelübergangs zurückgeführt wird.
Evaluating the feasibility of a novel approach to increasing physical activity levels in breast cancer survivors : a RE-AIM analysis

description: Translating research interventions into community practice is critical for improving population level health. Project MOVE, is an innovative real-world approach to increasing physical activity (PA) levels in breast cancer (BC) survivors. BC survivors were given the opportunity to develop and implement a PA program with the help of action grants (microgrants and financial incentives). Utilising action grants towards increasing PA in BC survivors is both innovative and unique to the BC related literature, thus evaluating this novel approach is warranted. This study evaluated the feasibility of Project MOVE in terms of acceptability, practicality and satisfaction utilising the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework. A mixed-methods design was used to inform each RE-AIM dimension, via questionnaires (n=87), focus groups (n=10) and interviews (n=10). Reach was evaluated by the proportion of targeted individuals recruited. Effectiveness was evaluated by objective and perceived changes in PA. Adoption was evaluated by participant’s perceptions of process and acceptability to uptaking the program. Implementation was examined by barriers and facilitators to implementing the program as intended. Lastly, Maintenance was evaluated by participant retention and maintenance of PA. Assessments occurred at baseline and six months. The current study revealed that Project MOVE was well received by BC survivors. In terms of Reach, 82% of participants were BC survivors; Effectiveness, participants significantly increased PA levels from baseline to six months (p<0.001) and 72.3% felt Project MOVE helped increase PA levels; Adoption, 92.2% reported Project MOVE was highly appropriate for the BC survivor population and was accepted by 95.6% of BC survivors; Implementation, program focused on fitness rather than disease was important for engagement, leaders with BC and exercise expertise was essential to accommodate population specific barriers, and including other health education resources is warranted; Maintenance, participant retention was 83% at six months, 47% of participants reported they still engaged in PA together as a group and 87.5% were confident they would continue to be regularly active post-intervention. The present findings suggest Project MOVE is an acceptable and practical strategy for increasing PA among inactive BC survivors, particularly when it is delivered in a safe and supportive group environment.
