description: Polyacrylonitrile membranes (PAN) have high stability against chemical agents, making them suitable for a wide range of applications as such Ultrafiltration processes. Ultrafiltration membranes composed of PAN/Superfine powder activated carbon (S-PAC) mixtures can be a good research route, aiming the development of a new separation processes for water treatment. The association of materials to form a single product can have technological and economic advantages in separation processes. In this study, S-PAC impregnated into PAN membranes were prepared, characterized and used, as a case study, to remove diclofenac (DCF) from water. The membranes (PAN/S-PAC) were synthesized with different concentrations of S-PAC (0.2, 0.6, 1.0, 3.0 and 5.0 wt%) by a phase inversion process. The results of the TEM characterizations of the S-PAC indicated the presence of micro and nanoparticles (∼10 nm) and tending to form micrometric clusters. The infrared spectra of the membranes were characteristic of PAN; however, vibrational bands attributed to the S-PAC spectrum were also observed, which indicated an interaction between the materials. The case study showed an increase in the water flux and in the DCF rejection efficiency, for composite membranes (PAN/S-PAC) with higher concentration of S-PAC. The results of static adsorption tests indicated that the mechanism of DCF rejection occurred predominantly by adsorption. There were indications that the PAN/S-PAC membranes formed a composite material and the PAN/S-PAC (3.0) presented the best study composition given the results. Although the research is in its initial phase, the results indicated that the composition can improve many water treatment systems.
Nonequivalent Ensembles for the Mean-Field $ϕ^{6}$ Spin Model

description: We derive the thermodynamic entropy of the mean field $ϕ^{6}$ spin model in the framework of the micro-canonical ensemble as a function of the energy and magnetization. Using the theory of large deviations and Rugh's micro-canonical formalism we obtain the entropy and its derivatives and study the thermodynamic properties of $ϕ^{6}$ spin model. The interesting point we found is that like $ϕ^{4}$ model the entropy is a concave function of the energy for all values of the magnetization, but is non-concave as a function of the magnetization for some values of the energy. This means that the magnetic susceptibility of the model can be negative for some values of the energy and magnetization in the micro-canonical formalism. This leads to the inequivalence of the micro-canonical and canonical ensembles. It is also shown that this mean-field model displays a first-order phase transition due to the magnetic field. Finally we compare the results of the mean-field $ϕ^{6}$ and $ϕ^{4}$ spin models.

description: The present research investigates the effects of social exclusion on attitudes toward ethnic and religious minorities. Native-born German participants who were socially excluded rather than included reported greater approval for stricter legislation regarding the naturalization of immigrants (Study 1), reported greater prejudice against openly observant Muslims (Studies 2 and 3), and stronger agreement with the view that immigrants are financial burdens to the state (Study 4). Social exclusion threatens the sense of personal control, which in turn leads to stronger rejection of stigmatized outgroups (Study 3). When perceived control was experimentally enhanced, the social exclusion effect disappeared (Study 4). The theoretical and practical implications of these findings are discussed.

A hybrid modeling approach to simulating past-century understory solar irradiation in Alberta, Canada
Creators: name: Erickson, Adam Michael
Publisher: name: University of British Columbia
Year: 2017

description: In western Canada, the effects of warming and increasing human activity may alter the structure, composition, and function of forests, producing quantitatively and qualitatively different understory light conditions. While difficult to measure directly, process-based models may facilitate inference of historical forest states. Yet, existing models are limited in the dynamics they represent. A promising new approach in hybrid modeling, first demonstrated here, is the fusion of machine learning and process-based models to simulate pattern-based processes. The objective of this dissertation was to simulate the effects of past-century climate and fire conditions on understory global solar irradiation trajectories across a 25.2 million ha landscape in Alberta, Canada. The LANDIS-II forest landscape model was applied to simulate past-century changes to competition, fire, and regeneration. Simulated tree species and age maps were classified into landcover types. A regression model of canopy light transmission as a function of landcover and site index showed good fit with field observations (R2 = 0.94) and was applied to a classification of LANDIS-II outputs. Canopy light transmission was multiplied by mean annual bare-earth global solar irradiation to produce understory light maps. Empirical and semi- mechanistic fire models were also applied. A variant of stochastic gradient descent was applied for parameter optimization, improving fire model performance (R² = 0.96; ΔR²= +0.14). Simulations showed a mild decline in forested area across the 1923-2012 period, attributable to a velocity of warming three times faster than migration. Migration was primarily controlled by fire and secondarily by regeneration. Simulated understory light levels declined across the period due to reduced mortality rates, preceding a likely long-term increase in light attributable to reduced regeneration rates. The key innovations of this work are as follows: characterization of human-dominated fire regimes in western Alberta (Chapter 4); advancement of the TACA-GEM regeneration model (Chapter 5); development of an algorithm for fire model parameter optimization (Chapter 6); development of new LiDAR models of canopy light transmission (Chapter 7); demonstration of a new hybrid modeling approach to simulating pattern-based processes, applied to understory light (Chapter 8); demonstration of long-term climatic regulation of understory solar irradiation through forest regeneration (Chapter 8).

description: ExoMolHR is an empirical, high-resolution molecular spectrum calculator for the high-temperature molecular line lists available from the ExoMol molecular database. Uncertainties, where available, in recommended ExoMol datasets are used to select highly accurate spectral lines. These lines largely rely on empirical energy levels generated through the MARVEL (measured active rotation vibration energy levels) procedure, which is being systematically used to improve the energy and transition data provided by the ExoMol database. The freely accessible ExoMolHR database provides line positions with calculated intensities for a user-specified wavenumber/wavelength range and temperature. Spectra can be plotted on the ExoMolHR website (https://www.exomol.com/exomolhr/) or downloaded as a CSV file. Cross sections can be calculated using the Python program PyExoCross. The ExoMolHR database currently provides 24307135 spectral lines for 33 molecules and 58 isotopologues; these numbers will increase as the ExoMol database is updated.

Stochastic functional differential equations driven by Lévy processes and quasi-linear partial integro-differential equations

Subjects: subject: Probability (math.PR)

description: In this article we study a class of stochastic functional differential equations driven by Lévy processes (in particular, $α$-stable processes), and obtain the existence and uniqueness of Markov solutions in small time intervals. This corresponds to the local solvability to a class of quasi-linear partial integro-differential equations. Moreover, in the constant diffusion coefficient case, without any assumptions on the Lévy generator, we also show the existence of a unique maximal weak solution for a class of semi-linear partial integro-differential equation systems under bounded Lipschitz assumptions on the coefficients. Meanwhile, in the nondegenerate case (corresponding to $Δ^{α/2}$ with $α\in(1,2]$), based upon some gradient estimates, the existence of global solutions is established too. In particular, this provides a probabilistic treatment for the nonlinear partial integro-differential equations, such as the multi-dimensional fractal Burgers equations and the fractal scalar conservation law equations.

description: For more than two decades, capacitive sensing has played a prominent role in human-computer interaction research. Capacitive sensing has become ubiquitous on mobile, wearable, and stationary devices---enabling fundamentally new interaction techniques on, above, and around them. The research community has also enabled human position estimation and whole-body gestural interaction in instrumented environments. However, the broad field of capacitive sensing research has become fragmented by different approaches and terminology used across the various domains. This paper strives to unify the field by advocating consistent terminology and proposing a new taxonomy to classify capacitive sensing approaches. Our extensive survey provides an analysis and review of past research and identifies challenges for future work. We aim to create a common understanding within the field of human-computer interaction, for researchers and practitioners alike, and to stimulate and facilitate future research in capacitive sensing.

On the Achievability of Cramér-Rao Bound In Noisy Compressed Sensing

description: Recently, it has been proved in Babadi et al. that in noisy compressed sensing, a joint typical estimator can asymptotically achieve the Cramer-Rao lower bound of the problem.To prove this result, this paper used a lemma,which is provided in Akcakaya et al,that comprises the main building block of the proof. This lemma is based on the assumption of Gaussianity of the measurement matrix and its randomness in the domain of noise. In this correspondence, we generalize the results obtained in Babadi et al by dropping the Gaussianity assumption on the measurement matrix. In fact, by considering the measurement matrix as a deterministic matrix in our analysis, we find a theorem similar to the main theorem of Babadi et al for a family of randomly generated (but deterministic in the noise domain) measurement matrices that satisfy a generalized condition known as The Concentration of Measures Inequality. By this, we finally show that under our generalized assumptions, the Cramer-Rao bound of the estimation is achievable by using the typical estimator introduced in Babadi et al.

description: Objective: Type 2 diabetes is accompanied by increased mortality from coronary artery disease (CAD), but the mechanisms linking these conditions remain elusive. Hence, treatment of hyperglycaemia alone is not sufficient to avoid CAD in diabetes. Alternative views suggest that metabolic and vascular diseases share unifying cellular defects that could serve as targets for novel therapeutic strategies. Recently, a variant [single-nucleotide polymorphism (SNP); rs11212617] near the gene for ataxia telangiectasia mutated (ATM) has been associated with glycaemic response to metformin. Materials and methods: We determined rs11212617 in 240 male patients who underwent elective coronary angiography. Results: While the variant was not associated with glucose concentrations, the A allele was significantly associated with the presence of CAD (chi-square, p = 0.003), as well as with logarithmically transformed quantitative CAD indices [severe score (SS): 0.5 (0.4–0.6) vs 0.3 (0.2–0.5); extent score (ES): 2.63 (2.4–2.9) vs 1.94 (1.4–2.4), both p < 0.05, respectively]. Multivariate analysis revealed an independent association between the A allele with ES (β = 0.17, p < 0.01). Conclusion: Our data suggest that ATM-dependent signalling might play a role in the development of atherosclerotic vascular disease, but larger studies are necessary to substantiate such a hypothesis.

description: Given a Lipschitz domain $Ω$ in ${\mathbb R} ^N $ and a nonnegative potential $V$ in $Ω$ such that $V(x)\, d(x,\partial Ω)^2$ is bounded in $Ω$ we study the fine regularity of boundary points with respect to the Schrödinger operator $L_V:= Δ-V$ in $Ω$. Using potential theoretic methods, several conditions equivalent to the fine regularity of $z \in \partial Ω$ are established. The main result is a simple (explicit if $Ω$ is smooth) necessary and sufficient condition involving the size of $V$ for $z$ to be finely regular. An essential intermediate result consists in a majorization of $\int_A | {\frac {u} {d(.,\partial Ω)}} | ^2\, dx$ for $u$ positive harmonic in $Ω$ and $A \subset Ω$. Conditions for almost everywhere regularity in a subset $A $ of $ \partial Ω$ are also given as well as an extension of the main results to a notion of fine ${\mathcal L}_1 | {\mathcal L}_0$-regularity, if ${\mathcal L}_j={\mathcal L}-V_j$, $V_0,\, V_1$ being two potentials, with $V_0 \leq V_1$ and ${\mathcal L}$ a second order elliptic operator.

Psychological factors influencing women's postpartum mental health
Creators: name: Stansfield, Cat
Publisher: name: Lancaster University
Year: 2019

description: This thesis focuses on women’s mental health following childbirth. It
      contains two separate papers: a systematic literature review and an
      empirical paper.

      Section one, the paper titled “Psychosocial Factors and Severe Postpartum
      Mental Health Difficulties: A Systematic Literature Review” aimed to
      establish the psychosocial factors which may influence whether a woman
      experiences severe postpartum mental health difficulties. The paper
      synthesised fourteen quantitative studies. The articles used a variety of
      methods, included small sample sizes, and focused predominantly on
      demographic factors. With the exception of previous mental health
      difficulties, the results were conflicting and contradictory; therefore,
      no overall conclusion could be made as to which of these factors increased
      a woman’s risk of these experiences. The findings demonstrated that no
      psychosocial factors have been researched in relation to severe postpartum
      mental health difficulties. Future research is required to establish the
      interaction between various psychosocial factors in order to develop our
      understanding of how these factors make some women more vulnerable to
      these experiences than others.

      Section two, the empirical paper titled, “Factors Predicting the
      Occurrence of SubClinical Symptoms of Mania in New Mothers”, aimed to
      explore the relationship between postpartum (hypo)mania and psychological
      factors including: cognitive appraisal styles, rumination strategies,
      Behavioural Activation System (BAS) sensitivity, sleep deprivation and
      birth experience. Younger age, lower income, feeding method, greater
      normalising appraisal styles, hypomania-relevant experiences, dampening
      and emotion-focused rumination strategies were associated with higher
      levels of (hypo)mania. However, whether these factors significantly
      predicted higher scores was dependent on whether the Highs scale (Glover
      et al, 1994) or the Altman Self-Rating Mania Scale (Altman et al, 1994)
      was used to measure (hypo)mania. The paper concluded that the experience
      of (hypo)mania in the post-partum is likely to be the result of several,
      complex and interacting demographic and psychosocial factors. Future
      research is required to establish validated measures of (hypo)mania for
      the postpartum population.
Knotted strings and leptonic flavor structure

description: We propose a third idea for the explanation of the leptonic flavor structure in addition to the prominent approaches based on flavor symmetry and anarchy. Typical flavor patterns can be modeled by using mass spectra obtained from the discrete lengths spectrum of tight knots and links. We assume that a string theory model exists in which this idea can be incorporated via the Majorana mass structure of a type I seesaw model. It is shown by a scan over the parameter space that such a model is able to provide an excellent fit to current neutrino data and that it predicts a normal neutrino mass hierarchy as well as a small mixing angle θ_{13}. Startlingly, such scenarios could be related to the dimensionality of space time via an anthropic argument.

description: Background The growing social emergency represented by Alzheimer’s disease (AD) and the lack of medical treatments able to modify the disease course have kindled the interest in nonpharmacological therapies. Objective We introduced a novel nonpharmacological approach for people with AD (PWA) named Multidimensional Stimulation group Therapy (MST) to improve PWA condition in different disease domains: cognition, behavior, and motor functioning. Methods. Enrolling 60 PWA in a mild to moderate stage of the disease, we evaluated the efficacy of MST with a randomized-controlled study. Neuropsychological and neurobehavioral measures and functional magnetic resonance imaging (fMRI) data were considered as outcome measures. Results The following significant intervention-related changes were observed: reduction in Neuropsychiatric Inventory scale score, improvement in language and memory subscales of Alzheimer’s Disease Assessment Scale–Cognitive subscale, and increased fMRI activations in temporal brain areas, right insular cortex, and thalamus. Conclusions Cognitive-behavioral and fMRI results support the notion that MST has significant effects in improving PWA cognitive-behavioral status by restoring neural functioning.
Nonconventional limit theorems in discrete and continuous time via martingales

description: We obtain functional central limit theorems for both discrete time expressions of the form $1/\sqrt{N}\sum_{n=1}^{[Nt]}(F(X(q_1(n)),\ldots, X(q_{\ell}(n)))-\bar{F})$ and similar expressions in the continuous time where the sum is replaced by an integral. Here $X(n),n\geq0$ is a sufficiently fast mixing vector process with some moment conditions and stationarity properties, $F$ is a continuous function with polynomial growth and certain regularity properties, $\bar{F}=\int F\,d(μ\times\cdots\timesμ)$, $μ$ is the distribution of $X(0)$ and $q_i(n)=in$ for $i\le k\leq\ell$ while for $i>k$ they are positive functions taking on integer values on integers with some growth conditions which are satisfied, for instance, when $q_i$'s are polynomials of increasing degrees. These results decisively generalize [Probab. Theory Related Fields 148 (2010) 71-106], whose method was only applicable to the case $k=2$ under substantially more restrictive moment and mixing conditions and which could not be extended to convergence of processes and to the corresponding continuous time case. As in [Probab. Theory Related Fields 148 (2010) 71-106], our results hold true when $X_i(n)=T^nf_i$, where $T$ is a mixing subshift of finite type, a hyperbolic diffeomorphism or an expanding transformation taken with a Gibbs invariant measure, as well as in the case when $X_i(n)=f_i({Υ}_n)$, where ${Υ}_n$ is a Markov chain satisfying the Doeblin condition considered as a stationary process with respect to its invariant measure. Moreover, our relaxed mixing conditions yield applications to other types of dynamical systems and Markov processes, for instance, where a spectral gap can be established. The continuous time version holds true when, for instance, $X_i(t)=f_i(ξ_t)$, where $ξ_t$ is a nondegenerate continuous time Markov chain with a finite state space or a nondegenerate diffusion on a compact manifold. A partial motivation for such limit theorems is due to a series of papers dealing with nonconventional ergodic averages.

Study of scale effects of rock quality designation (RQD) measurements using a discrete fracture network approach
Creators: name: Wang, Rongzhen
Publisher: name: University of British Columbia
Year: 2017

description: RQD measurements are performed on the assumption that the drilling cores of the rock mass would be representative of in situ geological conditions. This thesis focuses on the use of Discrete Fracture Network (DFN) modelling to study the influence of core length on RQD measurements for synthetic “homogeneous” rock masses. An homogeneous rock mass is considered to have a measurable global volumetric intensity and representing a single geotechnical domain, without the occurrence of shear zones, fault zones and closely spaced weakness planes. For a given fracture intensity, the results show that the variability of RQD measurements decreases with increasing core length size, which is consistent with the concept of Representative Elementary Volume (REV). Furthermore, an attempt is made to demonstrate the link between DFN based fracture intensity indicators (i.e. Linear Intensity, P₁₀ and Volumetric Joint Count, P30) and RQD measurements. The analysis is repeated using field data collected at two different room-and-pillar mines, and the results further demonstrate the existence of a Representative Elementary Length (REL) for RQD measurements, analogue to the concept of REV. In this research, the REL of geometrical property P₂₁, which is the length of fracture traces per unit area of sampling plane, is compared to that of RQD. Using an implicit block search algorithm, the blockiness character of the synthetic rock masses is also studied with given fracture intensities used to measure RQD values.

description: We adapt existing statistical modeling techniques for social networks to study consumption data observed in trophic food webs. These data describe the feeding volume (non-negative) among organisms grouped into nodes, called trophic species, that form the food web. Model complexity arises due to the extensive amount of zeros in the data, as each node in the web is predator/prey to only a small number of other trophic species. Many of the zeros are regarded as structural (non-random) in the context of feeding behavior. The presence of basal prey and top predator nodes (those who never consume and those who are never consumed, with probability 1) creates additional complexity to the statistical modeling. We develop a special statistical social network model to account for such network features. The model is applied to two empirical food webs; focus is on the web for which the population size of seals is of concern to various commercial fisheries.

description: Cyclooxygenase (COX)-2 mediates ischemic pre- and postconditioning as well as anesthetic-induced preconditioning. However, the role of COX-1 and -2 in anesthetic-induced postconditioning has not been investigated. We evaluated the role of COX-1 and -2 in sevoflurane-induced postconditioning in vivo. Pentobarbital-anaesthetized male C57BL/6 mice were subjected to 45 minutes of coronary artery occlusion and 3 hours of reperfusion. Animals received either no intervention, the vehicle dimethyl sulfoxide (DMSO, 10 µL/g intraperitoneally), acetylsalicylic acid (ASA, 5 µg/g intraperitoneally), the selective COX-1 inhibitor SC-560 (10 µg/g intraperitoneally), or the selective COX-2 inhibitor NS-398 (5 µg/g intraperitoneally). 1.0 MAC (minimum alveolar concentration) sevoflurane was administered for 18 minutes during early reperfusion either alone or in combination with ASA, SC-560, and NS-398. Infarct size was determined with triphenyltetrazolium chloride. Statistical analysis was performed using 1-way and 2-way analyses of variance with post hoc Duncan testing. The infarct size in the control group was 44% ± 9%. DMSO (42% ± 7%), ASA (36% ± 6%), and NS-398 (44% ± 18%) had no effect on infarct size. Sevoflurane (17% ± 4%; P < .05) and SC-560 (26% ± 10%; P < .05) significantly reduced the infarct size compared with control condition. Sevoflurane-induced postconditioning was not abolished by ASA (16% ± 5%) and SC-560 (22% ± 4%). NS-398 abolished sevoflurane-induced postconditioning (33% ± 14%). It was concluded that sevoflurane induces postconditioning in mice. Inhibition of COX-1 elicits a myocardial infarct size reduction and does not abolish sevoflurane-induced postconditioning. Blockade of COX-2 abolishes sevoflurane-induced postconditioning. These results indicate that sevoflurane-induced postconditioning is mediated by COX-2.

description: The protection of assets, including IT resources, intellectual property and business processes, against security attacks has become a challenging task for organizations. From an economic perspective, firms need to minimize the probability of a successful security incident or attack while staying within the boundaries of their information security budget in order to optimize their investment strategy. In this paper, an optimization model to support information security investment decision-making in organizations is proposed considering the two convicting objectives (simultaneously minimizing the costs of countermeasures while maximizing the security level). Decision models that support the firms’ decisions considering the trade-off between the security level and the investment allocation are beneficial for organizations to facilitate and justify security investment choices.

description: Enthusiasm for minimally invasive thoracic surgery is increasing. Thoracoscopy plays a significant therapeutic role in the fibrinopurulent stage (stage II) of empyema, in which loculated fluid cannot often be adequately drained by chest tube alone. For some debilitated and septic patients, further procedures such as open-window thoracostomy (OWT) with daily wound care or vacuum-assisted closure (VAC) therapy are necessary. In the present article, we propose a new option of minimally invasive VAC therapy including a topical solution of the empyema without open-window thoracostomy (Mini-VAC-instill). Three patients who underwent surgery using this technique are also presented. The discussion is focused on the advantages and disadvantages of the approach.

description: We show that several important resource allocation problems in wireless networks fit within the common framework of Constraint Satisfaction Problems (CSPs). Inspired by the requirements of these applications, where variables are located at distinct network devices that may not be able to communicate but may interfere, we define natural criteria that a CSP solver must possess in order to be practical. We term these algorithms decentralized CSP solvers. The best known CSP solvers were designed for centralized problems and do not meet these criteria. We introduce a stochastic decentralized CSP solver and prove that it will find a solution in almost surely finite time, should one exist, also showing it has many practically desirable properties. We benchmark the algorithm's performance on a well-studied class of CSPs, random k-SAT, illustrating that the time the algorithm takes to find a satisfying assignment is competitive with stochastic centralized solvers on problems with order a thousand variables despite its decentralized nature. We demonstrate the solver's practical utility for the problems that motivated its introduction by using it to find a non-interfering channel allocation for a network formed from data from downtown Manhattan.
Polarization-sensitive optical coherence tomography imaging of articular cartilage

description: Articular cartilage is the connective tissue protecting the joints, which can be divided into four structural zones from shallow to deep: superficial zone, transitional zone, deep zone and calcified zone. Osteoarthritis, a common joint disease, is associated with the progressive degeneration of the cartilage structure. The destruction progressively develops from the superficial zone towards the deep zone as the disease progresses. Thus, visualization of articular cartilage structural zones would significantly facilitate cartilage disease diagnosis, repair, regeneration, and transplantation. Polarization sensitive optical coherence tomography (PS-OCT) is a powerful non-invasive imaging modality capable of evaluating the birefringent properties in biological tissue such as collagen. The second harmonic generation (SHG) imaging in multiphoton microscopy (MPM) can provide complementary high-resolution imaging of the microscopic structure of collagen fibers. In this thesis, we apply both PS-OCT and SHG imaging on articular cartilage. An automated 3-D segmentation method based on PS-OCT phase retardation measurement is developed to differentiate the structural zones of articular cartilage. Since the collagen fiber organization varies from the tissue surface to deep regions, the depth-resolved phase retardation measured by PS-OCT is utilized to distinguish and segment the depth-related structural zones of cartilage tissue. The segmentation results are validated by the high-resolution SHG imaging. This method offers a novel quantification and tissue segmentation approach based on the phase retardation measurement by PS-OCT. A comparison between PS-OCT and SHG imaging on articular cartilage is also carried out. Based on the multilayer architecture of articular cartilage, various features extracted from PS-OCT and SHG are compared along the tissue depth. The segmentation method is implemented to distinguish the tissue layers based on the birefringence property. The segmentation results match well with the different quantification results achieved from the top-view and side-view illumination PS-OCT, and some features extracted from SHG, such as the SHG intensity and the collagen fiber orientation. The results show reasonable association between the tissue birefringence detected by PS-OCT and the fiber organization detected by SHG microscopy. PS-OCT and SHG are capable to analyze both the macro and micro characteristics of collagen fibers in articular cartilage, showing great potential in detecting related disease progression.
Don’t Do It Again! Directed Forgetting of Habits

description: Most daily routines are determined by habits. However, the experienced ease and automaticity of habit formation and execution come at a cost when habits that are no longer appropriate must be overcome. So far, proactive and reactive control strategies that prevent inappropriate habit execution either by preparation or “on the fly” have been identified. Here, we present evidence for a third, retroactive control strategy. In two experiments using the list method of directed forgetting, the accessibility of newly learned and practiced stimulus-response rules was significantly reduced when participants were cued to forget the rules rather than to remember them. The results thus show that directed forgetting, so far observed and investigated only for episodic memory traces, can also be applied to habits. The findings further emphasize the adaptive value of forgetting and can be taken as evidence of a retroactive strategy of habit control.

description: Background: Fibroblast growth factor 19 (FGF19) is an enteric hormone regulating bile acid de novo synthesis by sensing ileal bile acid flux. However, the role of FGF19 in cholelithiasis has not yet been elucidated and therefore is investigated in the present study. Methods: Total mRNA and protein were isolated from ileal biopsies and used for tissue expression analysis. FGF19, 7α-hydroxycholesterol (7α-OH-Chol), 27-hydroxycholesterol (27-OH-Chol), and different bile acids were determined in the blood samples. Results: FGF19 serum levels did not differ between gallstone carriers and controls but were significantly decreased in the overweight individuals (−32%, p = 0.0002), irrespective of gallstone status (normalweight to overweight controls −29%, p = 0.0017; normalweight to overweight gallstone carriers −44%, p = 0.0338), and correlated inversely with bodyweight (p

description: We extract a nonnegative integer-valued invariant, which we call the "order of algebraic torsion", from the Symplectic Field Theory of a closed contact manifold, and show that its finiteness gives obstructions to the existence of symplectic fillings and exact symplectic cobordisms. A contact manifold has algebraic torsion of order zero if and only if it is algebraically overtwisted (i.e. has trivial contact homology), and any contact 3-manifold with positive Giroux torsion has algebraic torsion of order one (though the converse is not true). We also construct examples for each nonnegative k of contact 3-manifolds that have algebraic torsion of order k but not k - 1, and derive consequences for contact surgeries on such manifolds. The appendix by Michael Hutchings gives an alternative proof of our cobordism obstructions in dimension three using a refinement of the contact invariant in Embedded Contact Homology.

Contour Erasure and Filling-in: New Observations

description: Contour erasure is a newly established form of flicker adaptation that diminishes the saliency of object edges leading to their complete disappearance (Anstis, S. 2013. Journal of Vision, 13(2):25, 1–14). If these “disappeared” objects are then viewed on textured backgrounds, the observers experience filling-in, the illusory sense of background completion in the absence of physical input. In a series of observations, we demonstrate that contour erasure can greatly speed up the filling-in (or fading) of brightness. Based on these observations, we suggest that contour adaptation happens early in the magnocellular pathways.
