description: We present an overview on relational observables in gravity mainly from a loop quantum gravity perspective. The gauge group of general relativity is the diffeomorphism group of the underlying manifold. Consequently, general relativity is a totally constrained theory with vanishing canonical Hamiltonian. This fact, often referred to as the problem of time, provides the main conceptual difficulty towards the construction of gauge-invariant local observables. Nevertheless, within the framework of complete observables, that encode relations between dynamical fields, progress has been made during the last 20 years. Although analytic control over observables for full gravity is still lacking, perturbative calculations have been performed and within de-parameterizable toy models it was possible for the first time to construct a full set of gauge invariant observables for a background independent field theory. We review these developments and comment on their implications for quantum gravity.

description: We study the effect of a magnetic field on the pairing dynamics in two-flavor color superconducting dense quark matter. The study is performed in the weakly coupled regime of QCD at asymptotically high density, using the framework of the Schwinger-Dyson equation in the improved rainbow approximation. We show that the superconducting gap function develops a directional dependence in momentum space. Quasiparticles with momenta perpendicular to the direction of the magnetic field have the largest gaps, while quasiparticles with momenta parallel to the field have the smallest gaps. We argue that the directional dependence is a consequence of a long-range interaction in QCD. The quantitative measure of the ellipticity of the gap function is determined by a dimensionless ratio, proportional to the square of the magnetic field and inversely proportional to the fourth power of the quark chemical potential. For magnetic fields in stars, $B\lesssim 10^{18} G$, the corresponding ratio is estimated to be less than about $10^{-2}$, justifying the use of the weak magnetic field limit in all stellar applications.

description: Background
                Cholera is a highly infectious diarrheal disease spread via fecal contamination of water and food sources; it is endemic in parts of Africa and Asia and recent outbreaks have been reported in Haiti, the Zambia and Democratic Republic of the Congo. If left untreated, the disease can be fatal in less than 24 h and result in case fatality ratios of 30–50%.
                Cholera disproportionately affects those living in areas with poor access to water and sanitation: the long-term public health response is focused on improving water and hygiene facilities and access. Short-term measures for infection prevention and control, and disease characterization and surveillance, are impaired by diagnostic delays: culture methods are slow and rely on the availability of infrastructure and specialist equipment. Rapid diagnostic tests have shown promise under field conditions and further innovations in this area have been proposed.

                Methods
                This paper is the protocol for a systematic review focused on identifying current technologies and methods used for cholera diagnosis in stool, and detection in water. We will synthesize and appraise information on product technical specifications, accuracy and design features in order to inform infection prevention and control and innovation development.
                Embase, MEDLINE, CINAHL, Proquest, IndMed and the WHO and Campbell libraries will be searched. We will include studies reporting on field evaluations, including within-study comparisons against a reference standard, and laboratory evaluations reporting on product validation against field stool or water samples. We will extract data according to protocol and attempt meta-analyses if appropriate given data availability and quality.

                Discussion
                The systematic review builds on a previous scoping review in this field and expands upon this by synthesising data on both product technical characteristics and design features. The review will be of particular value to stakeholders engaged in diagnostic procurement and manufacturers interested in developing cholera or diarrheal disease diagnostics.

description: Recent observation of several microwave transitions in H2O2 from the interstellar medium [Astron. Astrophys., 531, L8 (2011)] raised interest to this molecule as yet another sensitive probe of the tentative variation of the electron-to-proton mass ratio mu. We estimate sensitivity coefficients of the microwave transitions in H2O2 to mu-variation. The largest coefficient for 14.8 GHz transition is equal to 37, which is comparable to highest sensitivities in methanol and an order of magnitude higher than sensitivity of the tunneling transition in ammonia.

Physical and computational models of Marangoni and buoyancy flow during dissolution
Creators: name: Chatterjee, Aniruddha
Publisher: name: University of British Columbia
Year: 2012

description: During the production of titanium products, the presence of aluminum-rich regions can cause Type II alpha stabilized defects which are deleterious to down-stream performance. Al-rich material can enter the melt via ballistic transfer from the melting hearth at various stages during electron beam cold hearth re-melting (EBCHR) of Ti-6Al-4V (Ti-6wt%Al-4wt%V) alloy. If this material is not fully dissolved and homogenized when solidification occurs, the ingot will contain Al-rich regions. Thus, in order to produce high-performance components for aerospace applications, titanium producers must understand the dissolution process for alloying elements entering the melt. To study and characterize the phenomena associated with the dissolution and homogenization of alloying elements during EBCHR processing of Ti-6Al-4V, a water-ethanol physical analogue model has been developed to simulate the thermal, compositional and fluid flow behavior that are active in the dissolution process. The physical model consists of a hot water solvent contained in a transparent cell (beaker) in which solidified ethanol or ice solute is dipped. The data generated from the physical model was used to validate a coupled thermal- fluid flow-composition model (developed in the commercial CFD code ANSYS CFX). The analogue model focuses on characterizing the effects of thermal and compositional variations on surface tension driven fluid flow (Marangoni flow) and buoyancy driven flow during the dissolution of a low density, low surface tension and low melting point solid material (frozen ethanol) in a high density, high surface tension and high melting point liquid (water), which was found to be analogous to the dissolution of solid Al in liquid Ti. In addition, the analogue model was also capable to predict the dissolution behavior when there was no compositional difference between the solute and the solvent. Based on a comparison of fluid flow pattern and interface shape, and temperature data obtained at discrete locations in the experimental and computational results, the numerical model has been shown to quantitatively and qualitatively predict the dissolution behavior observed in the physical process.

description: Background
                Simultaneous consideration of two neuropathological traits related to Alzheimer’s disease (AD) has not been attempted in a genome-wide association study.

                Methods
                We conducted genome-wide pleiotropy analyses using association summary statistics from the Beecham et al. study (PLoS Genet 10:e1004606, 2014) for AD-related neuropathological traits, including neuritic plaque (NP), neurofibrillary tangle (NFT), and cerebral amyloid angiopathy (CAA). Significant findings were further examined by expression quantitative trait locus and differentially expressed gene analyses in AD vs. control brains using gene expression data.

                Results
                Genome-wide significant pleiotropic associations were observed for the joint model of NP and NFT (NP + NFT) with the single-nucleotide polymorphism (SNP) rs34487851 upstream of C2orf40 (alias ECRG4, P = 2.4 × 10−8) and for the joint model of NFT and CAA (NFT + CAA) with the HDAC9 SNP rs79524815 (P = 1.1 × 10−8). Gene-based testing revealed study-wide significant associations (P ≤ 2.0 × 10−6) for the NFT + CAA outcome with adjacent genes TRAPPC12, TRAPPC12-AS1, and ADI1. Risk alleles of proxy SNPs for rs79524815 were associated with significantly lower expression of HDAC9 in the brain (P = 3.0 × 10−3), and HDAC9 was significantly downregulated in subjects with AD compared with control subjects in the prefrontal (P = 7.9 × 10−3) and visual (P = 5.6 × 10−4) cortices.

                Conclusions
                Our findings suggest that pleiotropy analysis is a useful approach to identifying novel genetic associations with complex diseases and their endophenotypes. Functional studies are needed to determine whether ECRG4 or HDAC9 is plausible as a therapeutic target.

description: A phase transition indicates a sudden change in the properties of a large system. For temperature-driven phase transitions this is related to non-analytic behavior of the free energy density at the critical temperature: The knowledge of the free energy density in one phase is insufficient to predict the properties of the other phase. In this paper we show that a close analogue of this behavior can occur in the real time evolution of quantum systems, namely non-analytic behavior at a critical time. We denote such behavior a dynamical phase transition and explore its properties in the transverse field Ising model. Specifically, we show that the equilibrium quantum phase transition and the dynamical phase transition in this model are intimately related.

description: Excavation along a gas pipeline route through central Lancashire has revealed a previously unknown pottery production site of 13th to 15th century date. The site, which lies south of the river Ribble, comprised oval gullies, representing possible truncated clamp kiln bases, together with associated ditches and pits and over 10,000 sherds of pottery. Three distinct areas produced evidence of pottery production, over a distance of nearly half a kilometre and suggesting a widespread industry. Most of the recovered pottery was utilitarian, but examples of this material have been recognised in Wigan and Lancaster, while parallels are seen in an area stretching from Lancashire to north Wales. Excavated kilns and associated pottery assemblages are rare both in Lancashire and north� west England as a whole. This makes the excavations at Potter Lane of particular importance, given the date range, the area over which the finds were made, and the possibility of contemporary settlement adjacent to the remains.
Measurements of B to J/psi pi0 and other CPV modes at Belle

description: We report the recent measurements of B0->J/psi pi0 and other CP violation modes at Belle. The CP asymmetry parameters for the decay B0 -> J/psi pi0 have previously been measured by BaBar and Belle experiments, but the results of mixing induced CP asymmetry (S=-nsin(2phi_1)) were not in good agreement with each other. Furthermore, the BaBar result lies outside the physically allowed region. Previous Belle measurements were based on 535M BB-bar pairs. We updated the measurements using the final Belle data set of 772M BB-bar pairs. The CP asymmetry parameters from a charmless B0-> Ks pi0 pi0 decay using final Belle data set and measurement of cos(2phi_1) in B0->D^(*)h0 using joint BaBar+Belle analysis will also be discussed.

description: Background
                Universities are increasingly implementing programs to effectively respond to and manage sport-related concussions (SRCs). One such effort is to develop common data elements (CDEs) and standardize data collection methods. The objectives of this study were to describe CDEs currently collected by Big Ten and Ivy League universities for SRC studies, and to compare the data collected with the core CDEs recommended by the National Institute of Neurological Disorders and Stroke (NINDS).

                Methods
                We conducted an anonymous cross-sectional online survey among medical staff at the 14 Big Ten and 8 Ivy League universities (one per university) between September and October 2015. The survey instrument, including 9 questions corresponding to the concussion data collected before, during, and after a concussion, was developed and pilot-tested before field use. We analyzed patterns of the concussion CDEs being collected, including when, what, and how the data were collected and stored, and compared them with the NINDS' recommended core CDEs.

                Results
                A total of 19 out of 22 universities were included, with 13 from Big Ten and 6 from Ivy-League universities. All 19 participating universities currently collected concussion data with athletes before, during, and after a concussion. Great similarities in data collection were observed at baseline and acutely post-concussion across participating universities. All 19 universities collected at least one of the ten recommended acute symptoms checklists, and 18 universities collected one of the four recommended core neuropsychological function cognitive measures. However, CDEs in the sub-acute and chronic timeframes were limited, with only 9 (47%) universities collecting post-concussion short to long term outcome data. While over 60% of universities collected and stored concussion data electronically, only 17% to 42% of data collected were readily available for research.

                Conclusions
                Significant inter-institutional similarities in acute concussion CDEs were found. Further efforts should focus on collecting sub-acute and chronic timeframe core CDEs and creating data access protocols to facilitate evidence-based concussion prevention and treatment for all collegiate athletes.

description: We studied the electric current induced in a two-dimensional electron gas by the spin current, in the presence of Rashba and cubic Dresselhaus spin-orbit interactions. We found out that the factor relating these currents is not universal, but rather depends on the origin of the spin current. Drastic distinction has been found between two cases: the spin current created by diffusion of an inhomogeneous spin density, and the pure homogeneous spin current. We found out that in the former case the ISHE electric current is finite, while it turns to zero in the latter case, if the spin-orbit coupling is represented by Rashba interaction.

description: Compact Galactic binaries where at least one member is a white dwarf or neutron star constitute the majority of individually detectable sources for future low-frequency space-based gravitational-wave (GW) observatories; they also form an unresolved continuum, the dominant Galactic foreground at frequencies below a few mHz. Due to the paucity of electromagnetic observations, the majority of studies of Galactic-binary populations so far have been based on population-synthesis simulations. However, recent surveys have reported several new detections of white-dwarf binaries, providing new constraints for population estimates. In this article, we evaluate the impact of revised local densities of interacting white-dwarf binaries on future GW observations. Specifically: we consider five scenarios that explain these densities with different assumptions on the formation of interacting systems; we simulate corresponding populations of detached and interacting white-dwarf binaries; we estimate the number of individually detectable GW sources and the magnitude of the confusion-noise foreground, as observed by space-based detectors with 5- and 1-Mkm arms. We confirm earlier estimates of thousands of detached-binary detections, but project only few ten to few hundred detections of interacting systems. This reduction is partly due to our assessment of detection prospects, based on the iterative identification and subtraction of bright sources with respect to both instrument and confusion noise. We also confirm earlier estimates for the confusion-noise foreground, except in one scenario that explains smaller local densities of interacting systems with smaller numbers of progenitor detached systems.

description: Background
                There are numerous challenges in including patients in a core outcome set (COS) study, these can vary depending on the patient group. This study describes current efforts to include patients in the development of COS, with the aim of identifying areas for further improvement and study.

                Methods
                Using the COMET database, corresponding authors of COS projects registered or published from 1 January 2013 to 2 February 2017 were invited via a personalised email to participate in a short online survey. The survey and emails were constructed to maximise the response rate by following the academic literature on enhancing survey responses. Personalised reminder emails were sent to non-responders. This survey explored the frequency of patient input in COS studies, who was involved, what methods were used and whether or not the COS development was international.

                Results
                One hundred and ninety-two COS developers were sent the survey. Responses were collected from 21 February 2017 until 7 May 2017. One hundred and forty-six unique developers responded, yielding a 76% response rate and data in relation to 195 unique COSs (as some developers had worked on multiple COSs). Of focus here are their responses regarding 162 COSs at the published, completed or ongoing stages of development. Inclusion of patient participants was indicated in 87% (141/162) of COSs in the published completed or ongoing stages and over 94% (65/69) of ongoing COS projects. Nearly half (65/135) of COSs included patient participants from two or more countries and 22% (30/135) included patient participants from five or more countries. The Delphi survey was reported as being used singularly or in combination with other methods in 85% (119/140) of projects. Almost a quarter (16/65) of ongoing studies reported using a combination of qualitative interviews, Delphi survey and consensus meeting.

                Conclusions
                These findings indicated that the Delphi survey is the most popular method of facilitating patient participation, while the combination of qualitative interviews, Delphi survey and consensus meetings is the most popular combination of methods. The increased inclusion of patient participants in the development of COSs is encouraging, as is the international approach to COS development that some developers are adopting.

description: Die vorliegende Arbeit beschäftigt sich mit der Auswertung zweier Umfragen, wel-che die Auswirkungen der neuen Gebührenordnung für Tierärzte (GOT) auf die Pferdehaltung in Deutschland analysieren. Die Umfragen richteten sich an Pferde-halter und Tierärzte und wurden online durchgeführt. Insgesamt nahmen 14.021 Pferdehalter und 250 Tierärzte an der Befragung teil. Die Ergebnisse lassen darauf schließen, dass die Anpassung der GOT zu einer erhöhten finanziellen Belastung für Pferdehalter beitragen. Auffallend ist, dass einige Pferdehalter berichten, sie nehmen aufgrund der gestiegenen Gebühren seltener tierärztliche Leistungen in Anspruch. Besonders kritisch wird die neue Hausbesuchsgebühr gesehen, welche für jeden behandelte Pferd anfällt und von vielen Pferdehaltern als unrecht emp-funden wird. Auf der anderen Seite berichten die befragten Tierärzte von gestiege-nen Einnahmen seit GOT-Novellierung, wodurch die wirtschaftliche Situation vieler Praxen verbessert wird. Gleichzeitig kommt es jedoch zu einer höheren Arbeitsbe-lastung durch den erhöhten sozialen Druck von Seiten der Kunden. Die Anpas-sung der Gebühren hat dazu beigetragen, das Berufsbild des Tierarztes attraktiver zu machen, was langfristig dem Fachkräftemangel entgegenwirken könnte. Trotz-dem gibt es auch unter den Tierätzen Bedenken hinsichtlich der Angemessenheit einiger neuen Gebühren und der möglichen negativen Folgen auf das Tierwohl, wenn Tierhalter aus Kostengründen notwendige Behandlungen hinauszögern oder ganz darauf verzichten. 

Die Ergebnisse der Umfragen werden ausführlich dargestellt und mit der bestehen-den Literatur in Zusammenhang gebracht. Es wird deutlich, dass die finanziellen Auswirkungen der GOT-Anpassung auf die Pferdehaltung groß sind und einer wei-teren Beobachtung bedürfen. Klar wird, dass die Anpassung der Gebühren not-wendig war, um das wirtschaftliche Handeln der Tierärzte zu ermöglichen. Möglich-erweise sind erneute Anpassungen notwendig, um zu ermöglichen, dass sowohl die wirtschaftliche Stabilität der Tierarztpraxen als auch das Wohl der Tiere gewähr-leistet bleiben.

Insgesamt liefert die Arbeit wertvolle Einblicke in die komplexen Zusammenhänge zwischen tierärztlichen Gebühren und der Pferdehaltung in Deutschland. Sie bietet eine fundierte Grundlage für weitere Forschungen und Diskussionen, um eine nachhaltige und faire Regelung der tierärztlichen Gebühren zu erreichen.

description: The wreck of a small boat found in the Ligurian sea (north west of Italy), known as 'Leudo del Mercante', and its cargo of pottery represent a unique case study of ceramic provenance and dating that can help in providing further insight about the coastal trade performed by minor ships in the Mediterranean regions. In this paper we review archaeological investigations on pottery and present results of instrumental analyses both on the cargo and on parts of the wooden hull. Our aim is to confirm the origin of the pottery and to try to solve the fundamental issue of dating. Elemental analysis of pottery was performed using PIXE (Particle Induced X-ray Emission); dating of wood samples from the hull was performed by radiocarbon Accelerator Mass Spectrometry (AMS). Both kinds of measurements were performed at the LABEC laboratory in Florence. The elemental composition of ceramic bodies shows that the pottery could have been produced in the area of Savona or Albisola, not far from the shipwreck site. With the detailed archaeological study of the cargo and using radiocarbon data, we can deduce that the boat was built, sailed and sunk most probably during the first half of the 16th century.

description: We consider information dissemination in a large $n$-user wireless network in which $k$ users wish to share a unique message with all other users. Each of the $n$ users only has knowledge of its own contents and state information; this corresponds to a one-sided push-only scenario. The goal is to disseminate all messages efficiently, hopefully achieving an order-optimal spreading rate over unicast wireless random networks. First, we show that a random-push strategy -- where a user sends its own or a received packet at random -- is order-wise suboptimal in a random geometric graph: specifically, $Ω(\sqrt{n})$ times slower than optimal spreading. It is known that this gap can be closed if each user has "full" mobility, since this effectively creates a complete graph. We instead consider velocity-constrained mobility where at each time slot the user moves locally using a discrete random walk with velocity $v(n)$ that is much lower than full mobility. We propose a simple two-stage dissemination strategy that alternates between individual message flooding ("self promotion") and random gossiping. We prove that this scheme achieves a close to optimal spreading rate (within only a logarithmic gap) as long as the velocity is at least $v(n)=ω(\sqrt{\log n/k})$. The key insight is that the mixing property introduced by the partial mobility helps users to spread in space within a relatively short period compared to the optimal spreading time, which macroscopically mimics message dissemination over a complete graph.

description: We study the effects of Cu substitution in Fe1.1Te, the non-superconducting parent compound of the iron-based superconductor, Fe1+yTe1-xSex, utilizing neutron scattering techniques. It is found that the structural and magnetic transitions, which occur at \sim 60 K without Cu, are monotonically depressed with increasing Cu content. By 10% Cu for Fe, the structural transition is hardly detectable, and the system becomes a spin glass below 22 K, with a slightly incommensurate ordering wave vector of (0.5-d, 0, 0.5) with d being the incommensurability of 0.02, and correlation length of 12 angstrom along the a axis and 9 angstrom along the c axis. With 4% Cu, both transition temperatures are at 41 K, though short-range incommensurate order at (0.42, 0, 0.5) is present at 60 K. With further cooling, the incommensurability decreases linearly with temperature down to 37 K, below which there is a first order transition to a long-range almost-commensurate antiferromagnetic structure. A spin anisotropy gap of 4.5 meV is also observed in this compound. Our results show that the weakly magnetic Cu has large effects on the magnetic correlations; it is suggested that this is caused by the frustration of the exchange interactions between the coupled Fe spins.

description: We introduce the Gauge Vector-Tensor (GVT) theory by extending the AQUAL's approach to the GravitoElectroMagnetism (GEM) approximation of gravity. GVT is a generally covariant theory of gravity composed of a pseudo Riemannian metric and two U(1) gauge connections that reproduces MOND in the limit of very weak gravitational fields while remains consistent with the Einstein-Hilbert gravity in the limit of strong and Newtonian gravitational fields. GVT also provides a simple framework to study the GEM approximation to gravity. We illustrate that the gravitomagnetic force at the edge of a galaxy can be in accord with either GVT or ΛCDM but not both. We also study the physics of the GVT theory around the gravitational saddle point of the Sun and Jupiter system. We notice that the conclusive refusal of the GVT theory demands measuring either both of the gravitoelectric and gravitomagnetic fields inside the Sun-Jupiter MOND window, or the gravitoelectric field inside two different solar GVT MOND windows. The GVT theory, however, will be favored by observing an anomaly in the gravitoelectric field inside a single MOND window.

Results from NA62/KOTO
Creators: name: Koval, Michal
Publisher: name: Zenodo
Year: 2019

description: A review of present experimental status of the K -> pi nu nubar decays is given in the talk. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the K+ -> pi+ nu nubar using a novel kaon decay-in-flight technique, while the KOTO experiment at JPARC aims to study the KL -> pi0 nu nubar decay. Both experiments produced new results in 2018. The NA62 experiment observed one candidate event, compatible with the Standard Model prediction. The KOTO experiment improved the existing upper limits on the branching ratio of the neutral kaon decay by an order of magnitude.
Analysis of multiple exceptional points related to three interacting eigenmodes in a non-Hermitian Hamiltonian

description: We have investigated the exceptional points (EPs) which are degeneracies of a non-Hermitian Hamiltonian, in the case that three modes are interacting with each other. Even though the parametric evolution of the modes cannot be uniquely determined when encircling more than two EPs once, we can recover the initial configuration of the modes by encircling two EPs three times or three EPs twice. We confirm our expectation by numerically calculating the modes of an open quantum system, two dielectric microdisks, and 3$\times$3 matrix model.

description: We consider steady-state current activity statistics for the one-dimensional totally asymmetric simple exclusion process (TASEP). With the help of the known operator algebra (for general open boundary conditions), as well as general probabilistic concepts (for the periodic case), we derive and evaluate closed-form expressions for the lowest three moments of the probability distribution function. These are confirmed, to excellent degree of accuracy, by numerical simulations. Further exact expressions and asymptotic approximations are provided for probability distributions and generating functions.

Maternal health literacy and physical fitness in early motherhood, child motor development, and home affordances
Creators: name: Dickson, Danika Brooke
Publisher: name: University of British Columbia
Year: 2012

description: Health literacy and health-related physical fitness are important variables affecting health across one’s lifespan. Importantly, certain lifespan periods are more vulnerable to changes in health behaviour than others. Due to lifestyle changes and the perception of increased barriers to exercise, regaining pre-pregnancy fitness levels is often difficult. To-date, little is known regarding health literacy and physical fitness in the early years of motherhood. Therefore, the first purpose was to examine differences in health-related physical fitness of health literate mothers with children between the ages of 18 to 36 months compared to health literate non-mothers. In addition, little is known about the influence of health literacy and the home affordances that mothers may provide. As such, the second purpose was to examine whether health literate mothers provide environments with greater opportunities for child development (vs. mothers with low literacy). Sixteen mothers (31.9±3.8y) with a child between the age of 18 and 36 mo and 15 childless women (28.6±5.1y) completed a health literacy battery (Newest Vital Sign (NVS), Rapid Estimate of Adult Literacy in Medicine (REALM), Test of Functional Health Literacy in Adults (TOFHLA)), the Canadian Physical Activity, Fitness, and Lifestyle Approach (CPAFLA), and a physical activity questionnaire. Mothers also completed an Affordances of the Home Environment Motor Development (AHEMD) assessment. Sixteen toddlers (31±6mo) were assessed for motor development using the Peabody Developmental Motor Scales, 2nd Edition (PDMS-2). Results showed that all women demonstrated high health literacy levels. Non-mothers demonstrated greater health related physical fitness for push-ups (p=.009), partial curl-ups (p=.007), and vertical jump (p=.033) vs. mothers. In contrast, mothers performed significantly better on grip strength (p=.043). There was a trend between higher reading scores (REALM) with greater total variety of stimulation (r(15)=0.73, p=0.060) in the home environment. Increased variety of stimulation was positively correlated with locomotion (r(15)=0.88, p=0.008), object manipulation (r(15)=0.95, p=0.001), and visual-motor integration (r(15)=0.85, p=0.015) scores (PDMS-2). Despite similar health literacy levels, non-mothers demonstrated greater physical fitness; while mothers exhibited fitness levels associated with suboptimal health. Health literate mothers are more likely to expose their children to an environment that leads to greater proficiency on motor development tests.

description: The (over)completeness of even and odd nonlinear charge coherent states is proved and their generation explored. They are demonstrated to be generalized entangled nonlinear coherent states. A $D$-algebra realization of the SU$_f$(1,1) generators is given in terms of them. They are shown to exhibit SU$_f$(1,1) squeezing and two-mode $f$-antibunching for some particular types of $f$-nonlinearity, but neither one-mode nor two-mode $f$-squeezing.
