description: Quantum interference of "clocks", namely of particles with time-evolving internal degrees of freedom (DOFs), is a promising avenue to test genuine general relativistic effects in quantum systems. The clock acquires which path information while experiencing different proper times on traversing the arms of the interferometer, leading to a drop in its path visibility. We consider scenarios where the clock is subject to environmental noise as it transits through the interferometer. In particular, we develop a generalized formulation of interferometric visibility affected by noise on the clock. We find that, for small noise and small proper time difference between the arms, the noise further reduces the visibility, while in more general situations it can either increase or reduce the visibility. As an example, we investigate the effect of a thermal environment constituted by a single field mode and show that the visibility drops further as the temperature is increased. Additionally, by considering noise models based on standard quantum channels, we show that interferometric visibility can increase or decrease depending on the type of noise and also the time scale and transition probabilities. The quantification of the effect of noise on the visibility -- particularly in the case of a thermal environment paves the way for a better estimate on the expected outcome in an actual experiment.

COMMENTS: In the original description, Stresemann designated as the type of sinica a female from Ching-Feng collected on 21 December 1897. This is the only specimen that came to AMNH from the Rothschild Collection with those data, and it bears a Rothschild type label. Stresemann did not mention other specimens.
Stresemann, finding Corvus sinensis Latham, 1790, to be unidentifiable and best considered a nomen oblitum and needing a name for Chinese birds, provided the name sinica, based on the Fujian specimen available to him.

description: The present sample of nearby bulgelike dwarf stars has kinematics and metallicities characteristic of a probable inner disk or bulge origin. Ages derived by using isochrones give 10-11 Gyr for these stars and metallicities are in the range -0.80< [Fe/H]< +0.40. We calculate stellar parameters from spectroscopic data, and chemical abundances of Mg, Si, Ca, Ti, La, Ba, Y, Zr and Eu are derived by using spectrum synthesis. We found that [alpha-elements/Fe] show different patterns depending on the element. Si, Ca and Ti-to-iron ratios decline smoothly for increasing metallicities, and follow essentially the disk pattern. O and Mg, products of massive supernovae, and also the r-process element Eu, are overabundant relative to disk stars, showing a steeper decline for metallicities [Fe/H] > -0.3 dex. [s-elements/Fe] roughly track the solar values with no apparent trend with metallicity for [Fe/H] < 0, showing subsolar values for the metal rich stars. Both kinematical and chemical properties of the bulgelike stars indicate a distinct identity of this population when compared to disk stars.

description: We estimate the upper and lower bounds of the Hewitt$\textbf{-}$Stromberg dimensions. In particular, these results give new proofs of theorems on the multifractal formalism which is based on the Hewitt$\textbf{-}$Stromberg measures and yield results even at points $q$ for which the upper and lower multifractal Hewitt$\textbf{-}$Stromberg dimension functions differ. Finally, concrete examples of a measure satisfying the above property are developed.

description: Designation of Stigmella purpurimaculae group
 Species groups in Nepticulidae are highly valuable for diagnostic purposes to make associations easier, especially in such large genera as Stigmella Schrank, with about 400 species described worldwide (also see Stonis et al. 2013a). In the present paper, we designated one more species group, the purpurimaculae group, for the species which possess remarkable genitalia characters: the partially reduced tube of the phallus (Figs 5, 6), the dentate cornuti (Figs 5, 6), and the strongly developed utriculus in the female genitalia, which can be equal or longer than the corpus bursae (Fig. 4). The later two characters are unique among Nepticulidae and hitherto were unknown in the family, while the partial reduction of the phallus is also shared with two other species described in the current paper but not attributed to the purpurimaculae group.
Characters of morphology: forewing often with an apical purple spot; androconial scales absent; frontal tuft varies from fuscous brown to orange (Fig. 3); in the male genitalia, gnathos often broadly U-shaped, anterior processes of gnathos short or absent, chitinization of phallus reduced on distal part (partial reduction of phallus), vesica with numerous small dentate cornuti, manica absent; in the female genitalia, accessory sac weakly defined, ductus spermathecae strongly chitinized; utriculus unusually developed (as a large sac, sometimes even longer than corpus bursae); unique short, thickened spines sometimes occur in distal part of corpus bursae, signa absent.
 Host-plant preferences unknown. More than 16 male and female adults of three species of the purpurimaculae group (S. purpurimaculae sp. nov., S. cana sp. nov., S. truncata sp. nov.) were collected around the Lenga beech – Nothofagus pumilio (Poepp. & Endl.) Krasser, Nothofagaceae, but there is insufficient evidence that Nothofagus is the host-plant.
Distribution and taxonomic diversity: the group currently comprises 7 species (all described as new in the current paper, and all occurring in the southern Andes.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Matter collineations of spherically Symmetric Lorentzian Manifolds are considered. These are investigated when the energy-momentum tensor is non-degenerate and also when it is degenerate. We have classified spacetimes admitting higher symmetries and spacetimes admitting SO(3) as the maximal isometry group. For the non-degenerate case, we obtain either {\it four}, {\it six}, {\it seven} or {\it ten} independent matter collineations in which {\it four} are isometries and the rest are proper. The results of the previous paper [1] are recovered as a special case. It is worth noting that we have also obtained two cases where the energy-momentum tensor is degenerate but the group of matter collineations is finite-dimensional, i.e. {\it four} or {\it ten}.

title: PETRONIUS: PROTEST OR SENSATIONALISM?
Creators: name: McLeish, Duncan Riddell Ruthven
Publisher: name: The Open University
Year: 2002

description: This thesis examines the questions surrounding the Roman novelist Petronius and his work. Scholarship has over his aims: ranging from an attack on the moral standards of the day to being purely for entertainment. The introduction explores some of these, along with the basic details of Petronius' life, and sets out the basis for the thesis. Much of Petronius' work seems affected by dissimulatio: the necessity to hide one's true aims and feelings in the time of Nero. The historical, social and political background of that situation is examined; particularly with regard to Petronius' possible relationship with the emperor and with society as a whole, and his protest thereat - both direct and indirect, serious and amusing. Then the literary background to the novel is examined, especially with regard to Petronius' possible relationship with, and protest at his literary contemporaries, Seneca the Younger and Lucan; along with the alleged educational and literary decline of that age. Petronius' place in the field of Roman satire is also explored. The historical and social background of the sensationalist nature of much of Petronius' work is next considered, mainly with regard to public entertainment. Its effect on other writers is noted along with its possible effect on Petronius and his audience. Consideration is given to the possible nature and extent of that audience. Special attention is paid to the effect of the theatre on Petronius' work. The mime is closely studied because of its marked effect on the content and nature of the work. The conclusion examines the problems that the above raises and summarises commentators' solutions to them. The final section balances the evidence and concludes that, while Petronius was a protester and, to a greater extent, a sensationalist, he was primarily an entertainer.

description: High resolution X-ray spectra of the Reflection Grating Spectrometer (RGS) on board the XMM satellite are used to resolve the oxygen K absorption edge. By combining spectra of low and high extinction sources, the observed absorption edge can be split in the true interstellar (ISM) extinction and the instrumental absorption. The detailed ISM edge structure closely follows the edge structure of neutral oxygen as derived by theoretical R-matrix calculations. However, the position of the theoretical edge requires a wavelength shift. In addition the detailed instrumental RGS absorption edge structure is presented. All results are verified by comparing to a subset of Chandra LETG-HRC observations.

LECTOTYPE: AMNH 676157, adult male, collected at Taibai Shan (= Tai-Pai-Shan), 33.57N, 107.45E (BirdLife International, 2001: 2575), Quinling (= Tsinling) Mountains, Shaanxi, China, on 20 November 1905, by collectors for Alan Owston, no. 20915. From the Rothschild Collection.
COMMENTS: In the original description, Hartert noted that he had 45 specimens from the Tsinling Mountains, one from Sungpan and one from Peking, and saw seven specimens from Korea in BMNH. From them he designated as the type of interposita a male collected at Tai-pai-shan, Tsinling Mountains on 20 November 1905. There were two male specimens collected at that locality on that date, and by subsequently listing the specimen bearing the number 20915 as the type, he (Hartert, 1919: 124) designated it the lectotype. This is apparently a number adapted by Hartert from the date and written by him on the Rothschild Museum label of the lectotype, as the Rothschild Collection was not cataloged. The specimen also bears an Owston label and a Rothschild type label.
The specimen from Sungpan and the one from Peking did not come to AMNH; 42 of the 45 Tai-Pai-Shan specimens were cataloged at AMNH. The 41 paralectotypes are: AMNH 676122–676156, 676158–676162, 454361, 19 males and 22 females, collected July-November 1905, by collectors for Alan Owston, a specimen dealer in Yokohama. The seven specimens from Korea that Hartert saw in BMNH are also paralectotypes.

description: A large scale dynamical simulation of the superfluid to Mott insulator transition in the gas of ultra cold atoms placed in an optical lattice is performed using the time dependent Gutzwiller mean field approach. This approximate treatment allows us to take into account most of the details of the recent experiment [Nature 415, 39 (2002)] where by changing the depth of the lattice potential an adiabatic transition from a superfluid to a Mott insulator state has been reported. Our simulations reveal a significant excitation of the system with a transition to insulator in restricted regions of the trap.

description: Generative models in molecular design tend to be richly parameterized, data-hungry neural models, as they must create complex structured objects as outputs. Estimating such models from data may be challenging due to the lack of sufficient training data. In this paper, we propose a surprisingly effective self-training approach for iteratively creating additional molecular targets. We first pre-train the generative model together with a simple property predictor. The property predictor is then used as a likelihood model for filtering candidate structures from the generative model. Additional targets are iteratively produced and used in the course of stochastic EM iterations to maximize the log-likelihood that the candidate structures are accepted. A simple rejection (re-weighting) sampler suffices to draw posterior samples since the generative model is already reasonable after pre-training. We demonstrate significant gains over strong baselines for both unconditional and conditional molecular design. In particular, our approach outperforms the previous state-of-the-art in conditional molecular design by over 10% in absolute gain. Finally, we show that our approach is useful in other domains as well, such as program synthesis.

description: The current generation of covariant mean-field models has had many successes in calculations of bulk observables for medium to heavy nuclei, but there remain many open questions. New challenges are confronted when trying to systematically extend these models to reliably address nuclear structure physics away from the line of stability. In this lecture, we discuss a framework for the next generation of relativistic models that can address these questions and challenges. We interpret nuclear mean-field approaches as approximate implementations of Kohn-Sham density functional theory (DFT), which is widely used in condensed matter and quantum chemistry applications. We look to effective field theory (EFT) for a systematic approach to low-energy nuclear physics that can provide the framework for nuclear DFT.

description: The sodium-glucose cotransporter type 2 inhibitors reduce mortality and heart failure (HF) hospitalizations. The underlying mechanisms remain unclear but seem to be irrespective of glucose-lowering properties. This study aims to evaluate the impact of empagliflozin on myocardial biomechanics and correlation with markers of adverse remodeling. Following myocardial infarct induction to create a model of HF, 14 pigs were randomly assigned in a 1:1 ratio to receive either empagliflozin 10 mg daily or placebo for 2 months. Speckle-tracking echocardiography (STE) and feature-tracking cardiac magnetic resonance (FTCMR) were performed at baseline and at the end of the study to analyze myocardial deformation. The results were correlated with markers of adverse cardiac remodeling. Empagliflozin significantly improved STE indices. These parameters significantly correlated with adverse cardiac remodeling. In contrast, FTCMR indices showed only a trend toward improved myocardial deformation and without significant correlation with adverse cardiac remodeling. The correlation between both techniques to assess myocardial deformation was low. Empagliflozin enhances myocardial deformation, assessed by STE techniques, in a non-diabetic porcine model of ischemic HF. This may be related to a mitigation of adverse cardiac remodeling following ischemia reperfusion injury. In contrast, FTCMR technique needs further development and validation.

Our construction uses a combinatorial statement called the diamond principle, which is known to be consistent with but not provable from the standard axioms of set theory (assuming those axioms are consistent). We prove that the statement ``there exists a counterexample to Naimark's problem which is generated by $\aleph_1$ elements'' is undecidable in standard set theory.

description: The days that precede Valentine's Day are characterized by extensive gift shopping activities all across the globe. In China, where much shopping takes place online, there has been an explosive growth in e-commerce sales during Valentine's Day over the recent years. This exploratory study investigates the extent to which each product category and each shopper group can exhibit romantic love within China's e-market throughout the 2 weeks leading up to 2019 Valentine's Day. Massive data from Alibaba, the biggest e-commerce retailer worldwide, are utilized to formulate an innovative romance index (RI) to quantitatively measure e-romantic values for products and shoppers. On this basis, millions of shoppers, along with their millions of products purchased around Valentine's Day, are analyzed as a case study to demonstrate their love consumption and romantic gift-giving. The results of the analysis are then illustrated to help understand Chinese e-romance based on the perspectives of different product categories and shopper groups. This empirical information visualization also contributes to improving the segmentation, targeting, and positioning of China's e-market for Valentine's Day.

description: We investigate the dynamics of peeling of an adhesive tape subjected to a constant pull speed. We derive the equations of motion for the angular speed of the roller tape, the peel angle and the pull force used in earlier investigations using a Lagrangian. Due to the constraint between the pull force, peel angle and the peel force, it falls into the category of differential-algebraic equations requiring an appropriate algorithm for its numerical solution. Using such a scheme, we show that stick-slip jumps emerge in a purely dynamical manner. Our detailed numerical study shows that these set of equations exhibit rich dynamics hitherto not reported. In particular, our analysis shows that inertia has considerable influence on the nature of the dynamics. Following studies in the Portevin-Le Chatelier effect, we suggest a phenomenological peel force function which includes the influence of the pull speed. This reproduces the decreasing nature of the rupture force with the pull speed observed in experiments. This rich dynamics is made transparent by using a set of approximations valid in different regimes of the parameter space. The approximate solutions capture major features of the exact numerical solutions and also produce reasonably accurate values for the various quantities of interest.

description: We analyze three years (1998-2000) of OGLE observations of microlensing events to place limits on the abundance of planets with a planet-to-star mass ratio $q=10^{-3}$ at distances $\sim 1-4$AU from their host stars, i.e. `cool Jupiters'. We fit a total of 145 events using a maximum likelihood fit that adjusts 6 parameters. Each data point on the lightcurve allows us to exclude planets close to the two images of the source appearing on opposite sides of the Einstein ring of the lens star. We proceed to compute detection probability maps for each event, using $Δχ^2$ threshold values of 25, 60, 100 and combine the results from all events to place global constraints. Our selection criteria returned 5 candidate events for a planet with mass ratio $q=10^{-3}$. Only two of these remained as plausible candidates after three were rejected due to poor data quality at the time of the anomalies. Our results suggest that less than 21 ($n$)% of the lens stars have Jupiter-mass planets orbiting them at an orbital radius of $1 < a < 4$ AU. $n \le 2$ is the number of planet anomaly candidates that are actually due to planets. The datasets presented here were obtained from the DoPhot analysis of the events available at the OGLE website. The main conclusion of this work is that observing time is more efficiently allocated by observing many events with sampling intervals that produce non-overlapping detection zones than using intensive sampling on a small number of events.

Analyzing Differentiable Fuzzy Logic Operators

description: The AI community is increasingly putting its attention towards combining symbolic and neural approaches, as it is often argued that the strengths and weaknesses of these approaches are complementary. One recent trend in the literature are weakly supervised learning techniques that employ operators from fuzzy logics. In particular, these use prior background knowledge described in such logics to help the training of a neural network from unlabeled and noisy data. By interpreting logical symbols using neural networks, this background knowledge can be added to regular loss functions, hence making reasoning a part of learning. We study, both formally and empirically, how a large collection of logical operators from the fuzzy logic literature behave in a differentiable learning setting. We find that many of these operators, including some of the most well-known, are highly unsuitable in this setting. A further finding concerns the treatment of implication in these fuzzy logics, and shows a strong imbalance between gradients driven by the antecedent and the consequent of the implication. Furthermore, we introduce a new family of fuzzy implications (called sigmoidal implications) to tackle this phenomenon. Finally, we empirically show that it is possible to use Differentiable Fuzzy Logics for semi-supervised learning, and compare how different operators behave in practice. We find that, to achieve the largest performance improvement over a supervised baseline, we have to resort to non-standard combinations of logical operators which perform well in learning, but no longer satisfy the usual logical laws.

description: Specifying a computational problem requires fixing encodings for input and output: encoding graphs as adjacency matrices, characters as integers, integers as bit strings, and vice versa. For such discrete data, the actual encoding is usually straightforward and/or complexity-theoretically inessential (up to polynomial time, say); but concerning continuous data, already real numbers naturally suggest various encodings (so-called REPRESENTATIONS) with very different properties, ranging from the computably 'unreasonable' binary expansion via qualitatively to polynomially and even linearly complexity-theoretically 'reasonable' signed-digit expansion. But how to distinguish between un/suitable encodings of other spaces common in Calculus and Numerics, such as Sobolev? With respect to qualitative computability, Kreitz and Weihrauch (1985) had identified ADMISSIBILITY as crucial criterion for a representation over the Cantor space of infinite binary sequences to be 'reasonable'; cmp. [doi:10.1007/11780342_48]. Refining computability over topological to complexity over metric spaces, we develop the theory of POLYNOMIAL/LINEAR ADMISSIBILITY as two quantitative refinements of qualitative admissibility. We also rephrase quantitative admissibility as quantitative continuity of both the representation and of its set-valued inverse, the latter adopting from [doi:10.4115/jla.2013.5.7] a new notion of 'sequential' continuity for multifunctions. By establishing a quantitative continuous selection theorem for multifunctions between compact ultrametric spaces, we can extend our above quantitative MAIN THEOREM from functions to multifunctions aka search problems. Higher-type complexity is captured by generalizing Cantor's (and Baire's) ground space for encodings to other (compact) ULRAmetric spaces.

On equationally Noetherian and residually finite groups

description: The aim of this paper is to compare and contrast the class of residually finite groups with the class of equationally Noetherian groups - groups over which every system of coefficient-free equations is equivalent to a finite subsystem. It is easy to construct groups that are residually finite but not equationally Noetherian (e.g. the direct sum of all finite groups) or vice versa (e.g. the additive group $(\mathbb{Q},+)$ of the rationals). However, no explicit examples that are finitely generated seem to appear in the literature. In this paper, we show that among finitely generated groups, the classes of residually finite and equationally Noetherian groups are similar, but neither of them contains the other. On one hand, we show that some classes of finitely generated groups which are known to be residually finite, such as abelian-by-polycyclic groups, are also equationally Noetherian (answering a question posed by R. Bryant). We also give analogous results stating sufficient conditions for a fundamental group of a graph of groups to be equationally Noetherian and to be residually finite. On the other hand, we produce examples of finitely generated non-(equationally Noetherian) groups which are either residually torsion-free nilpotent or conjugacy separable, as well as examples of finitely presented equationally Noetherian groups that are not residually finite.

Nudging the Tap Open

description: The present study was a two phased investigation, inspecting the gap in literacy that leads to a preference for bottled water over tap water on the UBC Vancouver Campus. The second phase of this study explored the impact of choice architecture; particularly visual nudges, on diverting this preference. Our findings suggest that a visual nudge employing a pre-commitment strategy was the most effective in increasing self-reported use of tap water. This was followed by a visual nudge employing the ease and convenience technique, which pointed out the closest tap water facility. However, the small sample sizes and self-reported nature of the methodology renders these findings highly rudimentary and subject to critique.
