description: We present a simple model where the effective cosmological constant appears from chameleon scalar fields. For a Kachru-Kallosh-Linde-Trivedi (KKLT)-inspired form of the potential and a particular chameleon coupling to the local density, patches of approximately constant scalar field potential cluster around regions of matter with density above a certain value, generating the effect of a cosmological constant on large scales. This construction addresses both the cosmological constant problem (why $Λ$ is so small, yet nonzero) and the coincidence problem (why $Λ$ is comparable to the matter density now).

description: Using the Dirac-mode expansion method, which keeps the gauge invariance, we analyze the Polyakov loop in terms of the Dirac modes in SU(3) quenched lattice QCD in both confined and deconfined phases. First, to investigate the direct correspondence between confinement and chiral symmetry breaking, we remove low-lying Dirac-modes from the confined vacuum generated by lattice QCD. In this system without low-lying Dirac modes, while the chiral condensate $\langle \bar{q} q\rangle$ is extremely reduced, we find that the Polyakov loop is almost zero and $Z_3$-center symmetry is unbroken, which indicates quark confinement. We also investigate the removal of ultraviolet (UV) Dirac-modes, and find that the Polyakov loop is almost zero. Second, we deal with the deconfined phase above $T_c$, and find that the behaviors of the Polyakov loop and $Z_3$-symmetry are not changed without low-lying or UV Dirac-modes. Finally, we develop a new method to remove low-lying Dirac modes from the Polyakov loop for a larger lattice of $12^3 \times 4$ at finite temperature, and find almost the same results. These results suggest that each eigenmode has the information of confinement, i.e., the "seed" of confinement is distributed in a wider region of the Dirac eigenmodes unlike chiral symmetry breaking, and there is no direct correspondence between confinement and chiral symmetry breaking through Dirac-eigenmodes.

Neutral and Stable Equilibria of Genetic Systems and The Hardy-Weinberg Principle: Limitations of the Chi-Square Test and Advantages of Auto-Correlation Functions of Allele Frequencies

description: Since the foundations of Population Genetics the notion of genetic equilibrium (in close analogy to Classical Mechanics) has been associated to the Hardy-Weinberg (HW) Principle and the identification of equilibrium is currently assumed by stating that the HW axioms are valid if appropriate values of Chi-Square (p<0.05) are observed in experiments. Here we show by numerical experiments with the genetic system of one locus/two alleles that considering large ensembles of populations the Chi-Square test is not decisive and may lead to false negatives in random mating populations and false positives in nonrandom mating populations. As a result we confirm the logical statement that statistical tests can not be used to deduce if the genetic population is under the HW conditions. Furthermore, we show that under the HW conditions populations of any finite size evolve in time according to what can be identified as neutral dynamics to which the very notion of equilibrium is unattainable for any practical purpose. Therefore, under the HW conditions equilibrium properties are not observable. We also show that by relaxing the condition of random mating the dynamics acquires all the characteristics of asymptotic stable equilibrium. As a consequence our results show that the question of equilibrium in genetic systems should be approached in close analogy to non-equilibrium statistical physics and its observability should be focused on dynamical quantities like the typical decay properties of the allelic auto correlation function in time. In this perspective one should abandon the classical notion of genetic equilibrium and its relation to the HW proportions and open investigations in the direction of searching for unifying general principles of population genetic transformations capable to take in consideration these systems in their full complexity.

title: Effectiveness of time-lapse videos as a method to teach rates of surface geological processes
Creators: name: Schierl, Zachary P.
Publisher: name: Western Washington University
Year: 2014

description:
Understanding the wide range of rates at which geological processes operate can be challenging for introductory geology students, and yet is crucial to understanding how the Earth’s landscapes evolve over time. Research has shown that student misconceptions in this area are common. Time-lapse videos can capture processes that cannot be observed by students in the field and offer promise as a way to improves student understanding of rates of landscape evolution on certain timescales. This thesis explores the effectiveness of using time-lapse videos to teach intro geology students about the rates of surficial geological processes compared to before/after photo pairs depicting the same processes. The effect of interactivity on the effectiveness of time-lapse is also explored. One hundred and thirty students enrolled in introductory geology classes at Western Washington University during Winter and Spring quarter 2014 participated in the study. Subjects took a pre-test where they made qualitative and quantitative predictions about how various landscapes would change over time before completing a series of computer based activities containing before/after photos or time-lapse videos and then a post-test allowing them to revisit their predictions. The performance of three treatment groups, one using before/after photo pairs, one using pre-made time-lapse videos, and one where students made their own custom time-lapse videos using an interactive online program, was compared. All three groups exhibited large and statistically significant gains in understanding of geologic rates as measured by score gain from pre-test to post-test although differences in gains between groups were small and not significant. A number of steps were taken during study design and data analysis to ensure construct and internal validity. Lack of significant differences in the performance of the three treatment groups on the assessments suggests that there may be cognitive barriers to processing the complex and rapid landscape changes presented in a time-lapse video. This may limit how much students, in particular novice geology students, can learn from time-lapse videos, even though they inherently present more information and a more complete picture of a given geological process as compared to before/after photo pairs. The results of the study suggest various ways to improve the implementation and effectiveness of time-lapse videos in the geology classroom, including decreasing frame rates, more guidance on what to focus on when viewing time-lapse videos, inclusion of annotation and/or narration in the videos themselves, more time to look at the videos, and better integration of the videos and assessment questions. Extra care is also needed to ensure that videos explicitly address pre-existing misconceptions held by viewers in order for them to be effective with a wide range of students.

description: Speciation is a multifaceted process that involves numerous aspects of the biological sciences and occurs for multiple reasons. Ecology plays a major role, including both abiotic and biotic factors. Whether populations experience similar or divergent ecological environments, they often adapt to local conditions through divergence in biomechanical traits. We investigate the role of biomechanics in speciation using fish predator-prey interactions, a primary driver of fitness for both predators and prey. We highlight specific groups of fishes, or specific species, that have been particularly valuable for understanding these dynamic interactions and offer the best opportunities for future studies that link genetic architecture to biomechanics and reproductive isolation. In addition to emphasizing the key biomechanical techniques that will be instrumental, we also propose that the movement towards linking biomechanics and speciation will include 1) establishing the genetic basis of biomechanical traits, 2) testing whether similar and divergent selection lead to biomechanical divergence, and 3) testing whether/how biomechanical traits affect reproductive isolation. Future investigations that examine speciation through the lens of biomechanics will propel our understanding of this key process.

description: The Cherenkov Telescope Array (CTA) is a future very high energy gamma-ray observatory. CTA will be comprised of small-, medium- and large-size telescopes covering an energy range from tens of GeV to hundreds of TeV and will surpass existing telescopes in sensitivity by an order of magnitude. The aim of our study is to find the optimal design for the medium-size telescopes (MSTs), which will determine the sensitivity in the key energy range between a few hundred GeV to about ten TeV. To study the effect of the telescope design parameters on the array performance, we simulated arrays of 61 MSTs with 120 m spacing and a variety of telescope configurations. We investigated the influence of the primary telescope characteristics including optical resolution, pixel size, and light collection area on the total array performance with a particular emphasis on telescope configurations with imaging performance similar to the proposed Davis-Cotton (DC) and Schwarzschild-Couder (SC) MST designs. We compare the performance of these telescope designs, especially the achieved gamma-ray angular resolution and differential point-source sensitivity.

description: Both dust and silica phytoliths have been shown to contribute to reducing tooth volume during chewing. However, the way and the extent to which they individually contribute to tooth wear in natural conditions is unknown. There is still debate as to whether dental microwear represents a dietary or an environmental signal, with far reaching implications on evolutionary mechanisms which promote dental phenotypes such as molar hypsodonty in ruminants, molar lengthening in suids or enamel thickening in human ancestors.By combining controlled-food trials simulating natural conditions and dental microwear textural analysis on sheep, we show that the presence of dust on food items does not overwhelm the dietary signal. Our dataset explores variations in dental microwear textures between ewes fed on dust-free and dust-laden grass or browse fodders. Browsing diets with a dust supplement simulating Harmattan windswept environments contain more silica than dust-free grazing diets. Yet, browsers given a dust supplement differ from dust-free grazers. Regardless of the presence or the absence of dust, sheep with different diets yield significantly different dental microwear textures. Dust appears a less significant determinant of dental microwear signatures than the intrinsic properties of ingested foods, implying that diet plays a critical role in driving the natural selection of dental innovations.

description: The J-Ks color distribution (CD) with a bin size of 0.05 magnitude for the entire Milky Way has been carried out by using the Two Micron All Sky Survey Point Source Catalog (2MASS PSC). The CDs are bimodal, which has a red peak at 0.8 < J-Ks < 0.85 and a blue peak at 0.3 < J-Ks < 0.4. The colors of the red peak are more or less the same for the whole sky, but that of the blue peak depend on Galactic latitude, (J-Ks ~ 0.35 at low Galactic latitudes and 0.35 < J-Ks < 0.4 for other sky areas). The blue peak dominates the bimodal CDs at low Galactic latitudes and becomes comparable with the red peak in other sky regions. In order to explain the bimodal distribution and the global trend shown by the all sky 2MASS CDs, we assemble an empirical HR diagram, which is composed by observational-based near infrared HR diagrams and color magnitude diagrams, and incorporate a Milky Way model. In the empirical HR diagram, the main sequence stars turnoff the thin disk is relatively bluer, (J-Ks)0 = 0.31, when we compare with the thick disk which is (J-Ks)0 = 0.39. The age of the thin/thick disk is roughly estimated to be around 4-5/8-9 Gyr according to the color-age relation of the main sequence turnoff. In general, the 2MASS CDs can be treated as a tool to census the age of stellar population of the Milky Way in a statistical manner and to our knowledge this is a first attempt to measure the age.

description: We consider smooth complete intersection Calabi-Yau 3-folds in minuscule Schubert varieties, and study their mirror symmetry by degenerating the ambient Schubert varieties to Hibi toric varieties. We list all possible Calabi-Yau 3-folds of this type up to deformation equivalences, and find a new example of smooth Calabi-Yau 3-folds of Picard number one; a complete intersection in a locally factorial Schubert variety ${\boldsymbolΣ}$ of the Cayley plane ${\mathbb{OP}}^2$. We calculate topological invariants and BPS numbers of this Calabi-Yau 3-fold and conjecture that it has a non-trivial Fourier-Mukai partner.
The future of ward rounds and how we can transform the way our learners learn from ward rounds
Creators: name: Weien  Chow
Publisher: name: F1000 Research Limited
Year: 2023

description: Background:
 Ward rounds is an extremely important learning experience in the medical educational journey.
 There had previously been many proposed approaches to the conduct of ward rounds and ward round
 structures published in the literature. The COVID-19 pandemic also challenged the way how ward
 rounds could be conducted efficiently and how learners could learn effectively.

 Summary of Work:
 We critically examined and compared the use of different approaches in the conduct of ward rounds before, during and post COVID-19 pandemic. This includes a comprehensive review of previous approaches to the conduct of ward rounds published in the literature and how ward rounds have
 changed over the years such as the important use of electronic medical records and chart recalls
 which works well to facilitate learning during ward rounds. It was also observed that the COVID-19
 pandemic posed new challenges such as reduction in the duration of ward rounds due to the need to
 reduce exposure time to patients, reduction in the number of healthcare workers to conduct the ward
 rounds due to COVID-19 infection, home quarantine or lack of personal protective equipment (PPE)
 supplies and restriction of students from inpatient rotations.

 Summary of Results:
 Based on the review, it is proposed that the sequential use of pre-ward round meeting followed by ward round and post-ward round meeting provides the most effective outcomes of learning before, during and post COVID-19 pandemic and may be considered best practice. The use of virtual ward
 rounds and robotic-assisted ward rounds during the COVID-19 pandemic also provided a novel
 technological approach to enable the continued conduct of ward rounds while at the same time
 reducing the risk of COVID-19 exposure to healthcare workers and students.

 Discussion and Conclusion:
 Ward rounds continue to be a critical component of a learner’s educational journey. With the end of the COVID-19 pandemic worldwide, lessons learnt from the COVID-19 pandemic challenges us to transform and reimagine the way we conduct our ward rounds in the “new normal” and in an innovative way so as to improve the learning value and outcomes for our learners.

description:
In the last decades, many trace elements that were hitherto only used as geochemical proxies gained societal and economic importance due to their increasing use in high-technology applications including medicine and renewable energies. The increasing application of such metals results in a tremendously growing and unconstrained input from anthropogenic sources into the environment. Knowledge of the environmental behavior and the toxicity of these compounds are for many of these elements still in their infancy. The minute concentrations in the natural environment and complex matrices pose additional analytical challenges.

This contribution presents results on the anthropogenic and geogenic inputs of gadolinium, a major component in MRI contrast agents, and other emerging contaminants into the southern North Sea from the Elbe, Ems and Weser estuaries. The water samples were collected during research cruise M169 “TRAM” (“Tracing geogenic and anthropogenic critical high-technology metals in the southern North Sea”) with R/V Meteor.

Using Seafast-QQQ-ICPMS, we provide evidence for the widespread anthropogenic input/distribution of the wastewater-derived contaminant Gd in the southern North Sea, including the Wadden Sea World Heritage. Complementary ultrafiltration and DGT passive sampling data show that the anthropogenic Gd exclusively occurs in the truly dissolved element pool (< 1KDa) of the discharged river waters and is bound in a highly stable, inert complex that is not bioavailable. Our results corroborate the notion that the Gd-based contrast agents used during MRI scans may pass wastewater treatment plants unhindered and show a very conservative behavior during estuarine mixing, enabling its transport to the open sea.

description: Damages are created in a sacrificial layer of silicon dioxide by ion implantation to enhance the etch rate of silicon-dioxide in liquid and vapor phase hydrofluoric acid. The etch rate ratio between implanted and unimplanted silicon dioxide is more than 150 in vapor hydrofluoric acid (VHF). This feature is of interest to greatly reduce the underetch of microelectromechanical systems anchors. Based on the experimentally extracted etch rate of unimplanted and implanted silicon dioxide, the patterning of the sacrificial layer can be predicted by simulation.

description: Most antigenically novel and evolutionarily successful strains of seasonal influenza A (H3N2) originate in East, South and Southeast Asia. To understand this pattern, we simulated the ecological and evolutionary dynamics of influenza in a host metapopulation representing the temperate north, tropics and temperate south. Although seasonality and air traffic are frequently used to explain global migratory patterns of influenza, we find that other factors may have a comparable or greater impact. Notably, a region's basic reproductive number (R0) strongly affects the antigenic evolution of its viral population and the probability that its strains will spread and fix globally: a 17–28% higher R0 in one region can explain the observed patterns. Seasonality, in contrast, increases the probability that a tropical (less seasonal) population will export evolutionarily successful strains but alone does not predict that these strains will be antigenically advanced. The relative sizes of different host populations, their birth and death rates, and the region in which H3N2 first appears affect influenza's phylogeography in different but relatively minor ways. These results suggest general principles that dictate the spatial dynamics of antigenically evolving pathogens and offer predictions for how changes in human ecology might affect influenza evolution.

description: We introduce the concept of a nanoradar based on the operation of a nonlinear plasmonic nanoantenna. The nanoradar action originates from modulational instability occurred in a dimer nanoantenna consisting of two subwavelength nonlinear nanoparticles. Modulation instability causes a dynamical energy exchange between the nanoantenna eigenmodes resulting in periodic scanning of the nanoantenna scattering pattern. Such nanoradar demonstrates a wide scanning sector, low operation threshold, and ultrafast time response being potentially useful for many applications in nanophotonics circuitry.

description: Previous investigations of vision and visual pigment evolution in aquatic predators have focused on fish and crustacean, generally ignoring the cephalopods. Since the first cephalopod opsin was sequenced in late 1980s, we now have data on over 50 cephalopod opsins, prompting this functional and phylogenetic examination. Much of this data does not specifically examine the visual pigment spectral absorbance position (λmax) relative to environment or lifestyle and cephalopod opsin functional adaptation and visual ecology remain largely unknown. Here we introduce a new protocol for photoreceptor microspectrophotometry (MSP) that overcomes the difficulty of bleaching the bistable visual pigment and that reveals eight coastal coleoid cephalopods to be monochromatic with λmax varying from 484 to 505 nm. A combination of current MSP results, the λmax values previously characterized using cephalopod retinal extracts (467–500 nm) and the corresponding opsin phylogenetic tree were used for systematic comparisons with an end goal of examining the adaptations of coleoid visual pigments to different light environments. Spectral tuning shifts are described in response to different modes of life and light conditions. A new spectral tuning model suggests that nine amino acid substitution sites may determine the direction and the magnitude of spectral shifts.
title: Tracing silicate weathering using lithium isotopes: from the lab, to the field and the past
Creators: name: Pogge von Strandmann, Philip
Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)
Year: 2022

description:
Silicate weathering is the primary mechanism by which atmospheric CO2 is removed and stored for long periods of time. It is therefore a key biogeochemical mechanism in controlling the present and past climate, and may also have a significant role in future carbon dioxide removal. However, tracing silicate weathering is difficult in the modern environment, and have proven particularly challenging during geological history.

Lithium isotopes appear to be a tracer with significant potential in this field, because they only trace silicate weathering, and are apparently unaffected by biological processes.

Here we will present the behaviour of Li isotopes during weathering experiments and in the field. We will then demonstrate how this relates to Li isotope excursions through climatic events in Earth history, and what Li isotope data tell us about the operation of the “weathering thermostat” – the purported temperature-dependent stabilisation mechanism of the climate.

To test for temporal changes in BEF relationships, I assembled the pools of aquatic bacterial strains isolated at different time points from leaves on the pitcher plant Darlingtonia californica in order to evaluate the strength, direction and drivers of the BEF relationship across a natural host-associated successional gradient. I constructed experimental communities using bacterial isolates from each time point and measured their respiration rates and competitive interactions. Communities assembled from mid-successional species pools showed the strongest positive relationships between community richness and respiration rates, driven primarily by linear additivity among isolates. Diffuse competition was common among all communities but greatest within mid-successional isolates. These results demonstrate the dependence of the BEF relationship on the temporal dynamics of the local species pool, implying that ecosystems may respond differently to the addition or removal of taxa at different points in time during succession.

description: Active quantum error correction using qubit stabilizer codes has emerged as a promising, but experimentally challenging, engineering program for building a universal quantum computer. In this review we consider the formalism of qubit stabilizer and subsystem stabilizer codes and their possible use in protecting quantum information in a quantum memory. We review the theory of fault-tolerance and quantum error-correction, discuss examples of various codes and code constructions, the general quantum error correction conditions, the noise threshold, the special role played by Clifford gates and the route towards fault-tolerant universal quantum computation. The second part of the review is focused on providing an overview of quantum error correction using two-dimensional (topological) codes, in particular the surface code architecture. We discuss the complexity of decoding and the notion of passive or self-correcting quantum memories. The review does not focus on a particular technology but discusses topics that will be relevant for various quantum technologies.

description: Superconducting and antiferroquadrupolar (AFQ) transitions in a Pr-based compound PrRh2Zn20 have been found to occur simultaneously at Tc=TQ=0.06 K. The superconducting transition manifests itself by zero resistance and large diamagnetic susceptibility. The specific heat exhibits a Schottky anomaly peaking at 14 K and magnetization curves measured at 2 K show anisotropic behaviors. The analysis of these data indicates that the crystalline electric field (CEF) ground state of the trivalent Pr ion is the non-Kramers Gamma3 doublet with the quadrupolar degrees of freedom. A sharp peak in the specific heat at 0.06 K has been attributed not to the superconducting transition but to the AFQ transition because the ordering temperature TQ decreases in B || [100] but increases in B || [110] and B || [111] with increasing B up to 6 T. This anisotropic behavior of TQ(B) can be well explained by a two-sublattice mean-field calculation, which corroborates the AFQ ordered state below TQ. The entropy release at TQ is only 10% of Rln2 expected for the Gamma3 doublet, suggesting possible interplay between the quadrupolar degrees of freedom and the superconductivity.

description: The expansion of pollinator-dependent crops, especially in the developing world, together with reports of worldwide pollinator declines, raises concern of possible yield gaps. Farmers directly reliant on pollination services for food supply often live in regions where our knowledge of pollination services is poor. In a manipulative experiment replicated at 23 sites across an Ethiopian agricultural landscape, we found poor pollination services and severe pollen limitation in a common oil crop. With supplementary pollination, the yield increased on average by 91%. Despite the heterogeneous agricultural matrix, we found a low bee abundance, which may explain poor pollination services. The variation in pollen limitation was unrelated to surrounding forest cover, local bee richness and bee abundance. While practices that commonly increase pollinators (restricted pesticide use, flower strips) are an integral part of the landscape, these elements are apparently insufficient. Management to increase pollination services is therefore in need of urgent investigation.

description: The pair production of squarks is one of the main search channels for supersymmetry at the LHC. We present a fully differential calculation of the next-to-leading order (NLO) SUSY-QCD corrections to the on-shell production of a pair of squarks in the Minimal Supersymmetric Standard Model (MSSM), supplemented by the leading-order decay of the squarks to the lightest neutralino and a quark. In addition, we use the Powheg method to match our NLO calculation with parton showers. To this end, the process was implemented in the Powheg-Box framework and interfaced with Pythia6 and Herwig++. We study the differential scale dependence and K-factors, and investigate the effects of the parton showers for a benchmark scenario in the constrained MSSM.
