description: We study the effect of a many-body interaction on inter-band oscillations in a two-band Bose-Hubbard model with external Stark force. Weak and strong inter-band oscillations are observed, where the latter arise from a resonant coupling of the bands. These oscillations collapse and revive due to a weak two-body interaction between the atoms. Effective models for oscillations in and out of resonance are introduced that provide predictions for the system's behaviour, particularly for the time-scales for the collapse and revival of the resonant inter-band oscillations.

description: A collective electron transfer (ET) process was discovered by studying the current noise in a field effect transistor with light-sensitive gate formed by nanocrystals linked by organic molecules to its surface. Fluctuations in the ET through the organic linker are reflected in the fluctuations of the transistor conductivity. The current noise has an avalanche character. Critical exponents obtained from the noise power spectra, avalanche distributions, and the dependence of the average avalanche size on avalanche duration are consistent with each other. A plausible model is proposed for this phenomenon

description:
Background The duration and impact of the COVID-19 pandemic depends in a large part on individual and societal actions which is influenced by the quality and salience of the information to which they are exposed. Unfortunately, COVID-19 misinformation has proliferated. To date, no systematic efforts have been made to evaluate interventions that mitigate COVID-19-related misinformation. We plan to conduct a scoping review that seeks to fill several of the gaps in the current knowledge of interventions that mitigate COVID-19-related misinformation. Methods A scoping review focusing on interventions that mitigate COVID-19 misinformation will be conducted. We will search (from January 2020 onwards) MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science Core Collection, Africa-Wide Information, Global Health, WHO Global Literature on Coronavirus Disease Database, WHO Global Index Medicus, and Sociological Abstracts. Gray literature will be identified using Disaster Lit, Google Scholar, Open Science Framework, governmental websites, and preprint servers (e.g., EuropePMC, PsyArXiv, MedRxiv, JMIR Preprints). Study selection will conform to Joanna Briggs Institute Reviewers’ Manual 2020 Methodology for JBI Scoping Reviews. Only English language, original studies will be considered for inclusion. Two reviewers will independently screen all citations, full-text articles, and abstract data. A narrative summary of findings will be conducted. Data analysis will involve quantitative (e.g., frequencies) and qualitative (e.g., content and thematic analysis) methods. Discussion Original research is urgently needed to design interventions to mitigate COVID-19 misinformation. The planned scoping review will help to address this gap.

Vortices in chiral, spin-triplet superconductors and superfluids

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Superconductors exhibit unconventional electronic and magnetic properties if the Cooper pair wave function breaks additional symmetries of the normal phase. Rotational symmetries in spin- and orbital spaces, as well as discrete symmetries such as space and time inversion, may be spontaneously broken. When this occurs in conjunction with broken global U(1) gauge symmetry, new physical phenomena are exhibited below the superconducting transition that are characteristic of the broken symmetries of the pair condensate. This is particularly true of vortices and related defects. Superconductors with a multi-component order parameter exhibit a variety of different vortex structures and closely related defects that are not possible in condensates belonging to a one-dimensional representation. In this article we discuss the structure of vortices in Fermionic superfluids and superconductors which break chiral symmetry, i.e. combined broken time-inversion and 2D parity. In particular, we consider the structure of vortices and defects that might be realized in thin films of 3He-A and the layered superconductor Sr2RuO4, and identify some of the characteristic signatures of broken chiral symmetry that should be revealed by these defects.

Proximate causes of colour variation in Poecilia
Creators: name: Senghore, Alieu
Publisher: name: University of British Columbia
Year: 2023

description: The mechanisms driving colour variation in organisms have long fascinated scientists. The occurrence of novel phenotypes through random mutations and other factors has always opened new avenues of research to understand the genetic basis and inheritance patterns of these phenotypes. Studying colour asymmetry is an additional way to account for the diverse colour patterns present in nature. In this thesis, I present an investigation into the inheritance pattern and genetic basis of pigmentation in two related Poeciliid species: (Poecilia wingei and Poecilia picta). Additionally, I conducted an analysis of asymmetry in a third related Poeciliid species, the guppy (Poecilia reticulata). The study on P. wingei aimed to understand the heritability and genetic basis of a mutation affecting melanin pigment production. For P. picta, the focus was on understanding the inheritance pattern and genetic basis of a red phenotype referred to as 'blush'. Breeding experiments were conducted, for both P. picta and P. wingei. Subsequently, genotyping of all offspring was performed to determine the inheritance pattern of the mutation in P. wingei and the inheritance pattern of the blush phenotype in P. picta. The findings revealed that the mutation in P. wingei was autosomal recessive, and the blush phenotype in P. picta was not Y-linked, similar to a previous study. Next, an analysis of colour asymmetry was conducted in P. reticulata artificially selected for a high and low proportion of orange, aiming to better understand colour asymmetry present in orange and black guppy ornaments. Fluctuating asymmetry was found to be the main form of asymmetry present in the selection lines, and orange ornaments were more symmetric than black. Furthermore, I figured out that FA in orange ornaments were weakly correlated with FA in black ornaments, indicating that the traits are differentially sensitive to developmental instability. Moreover, the investigation determined the presence of a sizable, albeit insignificant, effect of FA in orange. Finally, heritability calculations for FA in orange and black ornaments were revealed to be quite low. Overall, this thesis contributes valuable insights into the genetic basis, inheritance patterns, and asymmetry in colour pigmentation in some Poeciliid species.

description: Purpose: To compare the cycle threshold (Ct) values of tears and nasopharyngeal (NP) swab in severe COVID-19 ICU patients with positive NP swabs. Procedure: A cross-sectional study for the detection of SARS-CoV-2 by real-time RT-PCR on simultaneously collected NP swabs and tears was performed. Detailed demographic profile, including comorbidities, ocular, and systemic features were analyzed. Results: In the 78 cases, the mean tear positivity was 26.92% (21/78), 2 tear samples being positive despite a negative NP swab. The mean Ct value of tears and NP were 28.17 ± 4.76 and 23.71 ± 6.19, respectively (p= .003). None of the cases had ocular findings or relationship between tear positivity and comorbidity. Conclusions: The viral load of tears is less than the NP secretions with the possibility of prolonged shedding in tears. Tears act as an additional source of contact transmission in ICU that can possibly be decreased by frequent hand hygiene by the patient.

description: In the present work we show that a special family of materials, the metal carboxylates, may have entangled states up to very high temperatures. From magnetic susceptibility measurements, we have estimated the critical temperature below which entanglement exists in the cooper carboxylate \{Cu$_2$(O$_2$CH)$_4$\}\{Cu(O$_2$CH)$_2$(2-methylpyridine)$_2$\}, and we have found this to be above room temperature ($T_e \sim 630$ K). Furthermore, the results show that the system remains maximally entangled until close to $\sim 100$ K and the Bell's inequality is violated up to nearly room temperature ($\sim 290$ K).

description: The Raman gain of a probe light in a three-state $Λ$-scheme placed into a defect of a one-dimensional photonic crystal is studied theoretically. We show that there exists a pump intensity range, where the transmission and reflection spectra of the probe field exhibit \textit{simultaneously} occurring narrow peaks (resonances) whose position is determined by the Raman resonance. Transmission and reflection coefficients can be larger than unity at pump intensities of order tens of $μ$W/cm$^{2}$. When the pump intensity is outside this region, the peak in the transmission spectrum turns into a narrow dip. The nature of narrow resonances is attributed to a drastic dispersion of the nonlinear refractive index in the vicinity of the Raman transition, which leads to a significant reduction of the group velocity of the probe wave.

description: Aims: The detached shells carry information on their formation process, as well as on the small-scale structure of the circumstellar medium around AGB stars due to the absence of significant line-of-sight confusion. Methods: The youngest detached shells, those around the carbon stars R Scl and U Cam, are studied here in great detail in scattered stellar light with the Advanced Survey Camera on the Hubble Space Telescope. Quantitative results are derived assuming optically thin dust scattering. Results: The detached dust shells around R Scl and U Cam are found to be consistent with an overall spherical symmetry. They have radii of 19.2" (corresponding to a linear size of 8x10^16 cm) and 7.7" (5x10^16 cm), widths of 1.2" (5x10^15 cm) and 0.6" (4x10^15 cm), and dust masses of 3x10^-6 and 3x10^-7 M(Sun), respectively. The dynamical ages of the R Scl and U Cam shells are estimated to be 1700 and 700 yr, respectively, and the shell widths correspond to time scales of 100 and 50 yr, respectively. Small-scale structure in the form of less than arcsec-sized clumps is clearly seen in the images of the R Scl shell. Average clump dust masses are estimated to be about 2x10^-9 M(Sun). Comparisons with CO line interferometer data show that the dust and gas shells coincide spatially, within the errors (<=1" for U Cam and approx. 2" for R Scl). Conclusions: The results are consistent with the interpretation of geometrically thin gas and dust shells formed by a mass-loss eruption during a He-shell flash, and where interaction with a previous wind plays a role as well. Clumpy structure is present in the R Scl shell, possibly as a consequence of the mass loss itself, but more likely as a consequence of instabilities in the expanding shell.

Creators: name: McPheat, Graham
Publisher: name: Strathprints - University of Strathclyde
Year: 2009

description: This book details research which aimed to identify the ways in which the managers of effective residential homes work. The research involved the collection of quantitative data from 45 homes in England and Wales, 30 homes from the local authority and 15 homes based in the independent sector. It looked at managers' roles, as well as providing a consideration of resource use and leadership style. The research was motivated in part by the fact that previous research into this area, whilst highlighting significant variation in standards of practice, did not identify clearly those characteristics of managers that contributed to effective leadership. As such, the research upon which the book is based outlines the relationship between structure, process and outcomes.

description: A phase-field model for the Hele-Shaw flow of non-Newtonian fluids is developed. It extends a previous model for Newtonian fluids to a wide range of shear-dependent fluids. The model is applied to perform simulations of viscous fingering in shear- thinning fluids, and it is found to be capable of describing the complete crossover from the Newtonian regime at low shear rate to the strongly shear-thinning regime at high shear rate. The width selection of a single steady-state finger is studied in detail for a 2-plateaux shear-thinning law (Carreau law) in both its weakly and strongly shear-thinning limits, and the results are related to previous analyses. In the strongly shear-thinning regime a rescaling is found for power-law (Ostwald-de-Waehle) fluids that allows for a direct comparison between simulations and experiments without any adjustable parameters, and good agreement is obtained.
Energy Efficient Location Aided Routing Protocol for Wireless MANETs

Subjects: subject: Networking and Internet Architecture (cs.NI)
subject: FOS: Computer and information sciences

description: A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. In this paper we introduce an Energy Efficient Location Aided Routing (EELAR) Protocol for MANETs that is based on the Location Aided Routing (LAR). EELAR makes significant reduction in the energy consumption of the mobile nodes batteries by limiting the area of discovering a new route to a smaller zone. Thus, control packets overhead is significantly reduced. In EELAR a reference wireless base station is used and the network's circular area centered at the base station is divided into six equal sub-areas. At route discovery instead of flooding control packets to the whole network area, they are flooded to only the sub-area of the destination mobile node. The base station stores locations of the mobile nodes in a position table. To show the efficiency of the proposed protocol we present simulations using NS-2. Simulation results show that EELAR protocol makes an improvement in control packet overhead and delivery ratio compared to AODV, LAR, and DSR protocols.

description: Autobiography of my dead brother portrays the life of teenage Jesse, living in the ganglands of Harlem, downtown New York. As Jesse matures into another anonymous black teenager, he finds his life divided. Childhood friendships, traditional family values and church on the one hand, clash with the demands of 'being in the 'hood', gang warfare, guns and drugs on the other. Walter Dean Myer's graphic novel highlights the daily realities of being a black teenager in the city, and the fear and danger that have to be overcome to stay alive.

Conclusions: Our findings suggest that patients with long-term existence of SARS-CoV-2 at low detectable levels may not have active intraocular viral shedding. This is of particular importance as ophthalmic surgical procedures may potentiate virus spread from patients infected with SARS-CoV-2.
Three Roman Telescope Science Cases for Local Volume Galaxies
Creators: name: GuhaThakurta, Raja
Publisher: name: Zenodo
Year: 2021
Subjects: Connecting the near-field and deep-field view of galaxy formation

description: I will discuss three sample Roman Telescope near-field cosmology science cases: (1) Milky Way (MW) halo proper motions, (2) the edge of M31's stellar halo, and (3) globular clusters (GCs) in the Virgo cluster of galaxies. The three science cases are about the dark matter content, accretion history, and chemical enrichment history of Local Volume galaxies. The MW science case involves using 6D stellar kinematics to study its accretion history and dark matter content. Proper motions can be measured for faint stars in the remote halo of the MW using multi-epoch Roman Telescope images or by combining astrometry from single-epoch Roman Telescope images with earlier epoch astrometry from Gaia and HST. This could extend the domain of precise astrometry by 2 mag compared to what Gaia alone is capable of. These proper motion measurements will be supplemented by radial velocities (and chemical abundances) from ground based spectroscopy. The M31 case involves mapping its stellar halo out to r ~ 300 kpc and characterizing the "edge" of the halo at the splashback radius. The Roman Telescope's wide field of view and point source depth makes this possible. The Virgo cluster science case involves the identification and study of GCs. Most of these GCs are satellites of Virgo cluster galaxies whose dynamics and chemical abundances shed light on the formation history of their host galaxies. Some of the GCss are intracluster GCs that have been stripped from their original host galaxies.

Creators: name: Smith, Mark
Publisher: name: Strathprints - University of Strathclyde
Year: 2009

description: This is a brave book in which Keith White puts the words love and God on the centre stage. The book sets out to connect theology and child development. It also discusses insights from sociology, anthropology, philosophy and travel. Most tellingly, though, White draws on he and his wife’s lived experience of running Mill Grove, a residential child care community in London. The book is motivated by ‘the desire to understand better the lives, struggles, growth and development of particular children and families’ (p.10). This quest is grounded firmly in the day-to-day experience of caring for children. Writing from such an experiential base can appear rather quaint these days and provides a welcome antidote to policy overload and the ‘what works’ zeitgeist.
Biochar and activated biochar in a temperate climate : implications for dissolved organic carbon retention and leaching
Creators: name: Lambrecht, Freya

Year: 2023

description: Conventional agricultural practices contribute to soil degradation and soil organic carbon (SOC) losses. To address the climate crisis and improve soil quality, increasing the soil carbon pool through alternative agricultural practices is of global interest. Biochar shows promise in positively influencing SOC and soil quality. However, the strength of these benefits varies, especially on dissolved organic carbon (DOC), a labile form of carbon. Additionally, studies examining DOC concentrations past the growing season are limited. The chemical characteristics of the DOC quality are important indicators impacts on soil microbes, soil carbon stabilization and aquatic systems. Understanding biochar’s impact on DOC concentrations, flux and chemical characteristics is crucial for comprehending its role in SOC and carbon sequestration. This thesis examines the effects of biochar and manure-activated biochar amendments applied to experimental plots at Totem Field Plant Science Station on DOC concentrations, characteristics, and flux from August 2022 to March 2023. Results indicate that seasonal DOC concentrations are correlated with soil temperature. The activated biochar increased the average DOC concentrations and flux in the topsoil, while the pristine biochar decreased DOC concentrations in the fall and decreased the flux from the topsoil. Spectral analysis of the soil solution suggested that the biochar likely decreased the DOC concentrations and flux due to its capacity to retain the high-weight humic-like components in the DOM. Notably, treatment effects were predominantly limited to the topsoil, suggesting that the DOC became stabilized in the subsoil, whereas the pristine biochar stabilized DOC levels in the topsoil. This research highlights that biochar effects on DOC are affected by biochar properties as well as soil and climate characteristics. Understanding the effects of these amendments on carbon losses and storage at depth is crucial for decisions on biochar’s role in sustainable soil management practices.

description: The concepts of heuristics and biases underlie the decision-making process both at intuitive and rational levels, which Daniel Kahneman refers to as System 1 and System 2 of thinking. This research seeks to explore the interplay between these cognitive mechanisms and students’ grading decisions, examining the extent to which heuristics and biases can influence evaluation in the everyday process of learning and teaching. A survey was conducted, containing four grading situations that combine the experiences of reading, evaluation, and decision-making in four stages of System 1 and System 2 of thinking. The hypotheses and sub-hypotheses were tested using a quantitative approach, through a 15-item self-administered questionnaire (SAQ) in English, which collected data about the heuristics influencing Romanian students’ grading decision in four evaluative situations based on a synopsis of The Book Thief by Markus Zusak. The self-constructed questionnaire was filled in by 108 Romanian students studying for a bachelor’s, master’s, or doctoral degree in public and private universities. The data set was analyzed, using descriptive, inferential, and path-analysis methods (frequencies, percentages, measures of central tendency, t-tests, ANOVA, simple and multiple linear regression, mediation, and moderation) and one statistical program (R Studio 4.3.4.). Grade 1 (the most intuitive) can predict Grade 4 for the synopsis of The Book Thief. However, the correlation between Grades 2 + 3 and Grade 4 is much stronger than the correlation between Grade 1 and Grade 4. Furthermore, the impact of Grade 1 on Grade 4 is mediated by Grade 3 while Grade 1 has no effect on the impact of Grade 3 on Grade 4. The rational model of heuristics involved in the grading process is much stronger than the intuitive model. The study sheds light on the intricate interplay between intuition and rationality in the grading process, offering novel insights into the cognitive mechanisms that underlie decision-making.

description: J. Harer and D. Zagier have found a strikingly simple generating function for exact (all-genera) 1-point correlators in the Gaussian Hermitian matrix model. In this paper we generalize their result to 2-point correlators, using Toda integrability of the model. Remarkably, this exact 2-point correlation function turns out to be an elementary function - arctangent. Relation to the standard 2-point resolvents is pointed out. Some attempts of generalization to 3-point and higher functions are described.

description: Water is a key species in many astrophysical environments, but it is particularly important in proto-planetary disks. So far,observations of water in these objects have been scarce, but the situation should soon change thanks to the Herschel satellite. We report here a theoretical study of the water line spectrum of a proto-planetary disk surrounding Ae stars. We show that several lines will be observable with the HIFI instrument onboard the Herschel Space Observatory. We predict that some maser lines could also be observable with ground telescopes and we discuss how the predictions depend not only on the adopted physical and chemical model but also on the set of collisional coefficients used and on the H2 ortho to para ratio through its effect on collisional excitation. This makes the water lines observations a powerful, but dangerous -if misused- diagnostic tool.

The Roman Space Telescope: A Pathway to Measuring Accurate Distances to Every Galaxy in the Nearby Universe
Creators: name: McQuinn, Kristen
Publisher: name: Zenodo
Year: 2021
Subjects: Connecting the near-field and deep-field view of galaxy formation

description: With the near-infrared (NIR) capabilities of the Roman Telescope and the large sky coverage of community surveys, we will have the ability to measure robust distances to nearly every galaxy with M_*>10^6 Msun within ~20 Mpc, enabling fundamental science such as (i) placing all distance-dependent properties of galaxies in the nearby universe on an absolute scale, (ii) unambiguously associating galaxies with their environments including determining satellite luminosity functions for central galaxies and mapping galaxy groups/clusters, and (iii) providing an improved local calibration of H_0. Such distances will be possible with Roman using the tip of the red giant branch (TRGB) method, the most accurate and least expensive distance indicator for nearby galaxies. TRGB distances are traditionally measured from I-band data where the luminosity of TRGB stars has little dependency on stellar age and metallicity. In the NIR the TRGB is ~2 mag brighter offering observational gains over optical wavelengths, however, the NIR TRGB has a greater dependency on both stellar age and metallicity. I will present results on modeling the TRGB luminosity as a function of wavelength and show that variations in the NIR TRGB can be reduced to a 1-2% accuracy in distance with careful calibration. I will also present a new effort to empirically calibrate the NIR TRGB using HST IR imaging, providing a stepping stone to using both JWST and Roman NIR imaging to measure accurate TRGB distances.

description: Purpose: The authors present a case of unilateral orbital myositis of new onset following COVID-19 without a severe course. Methods: The patient had been received topical treatment with a preliminary diagnosis of conjunctivitis but no recovery had been noticed. The history revealed that the ocular signs had started 1 week after the COVID-19. Results: The examination revealed sectoral hyperemia of the temporal region in the bulbar conjunctiva together with marked limitation of right inward gaze. MRI of the orbits demonstrated diffuse fusiform enhancing enlargement of the right lateral rectus and superior rectus. The results of the laboratory tests and examination findings were normal. Systemic corticosteroids were started for the orbital myositis. Conclusions: Although conjunctivitis is the more common ocular disease following COVID-19, the possibility of orbital myositis should be considered in cases with resistance to topical treatment and/or gaze limitation. The possible role of orbital myositis as a trigger for COVID-19 could be explained with an immune-mediated mechanism.

Stellar Streams from Globular Clusters in the Local Universe

description: From the vast population of stellar streams in the Milky Way, we know that the morphology of thin, stellar streams, in particular, can be used to test the distribution and nature of dark matter. In the course of the next decade, a wealth of extragalactic stellar streams observations will become available, and stellar streams will be observed in galaxies out to several hundred Mpc. How will we take full advantage of these observations and decipher the astrophysical information the data contain? In this talk, I review the current and future prospects of detecting stellar streams in external galaxies with a focus on globular cluster streams. I create mock-stellar streams and inject them to data from the PAndAS M31 survey to produce simulated M31 backgrounds mimicking what the Nancy Grace Roman Space Telescope (Roman) will observe in M31. Additionally, I estimate the distance limit to which globular cluster streams will be observable. Recent results demonstrate that for a 1 hour exposure Roman should detect globular cluster streams in resolved stars in galaxies out to distances beyond 3.5 Mpc. This volume contains at least 199 galaxies of which > 90% are dwarfs. If these external galaxies do not host spiral arms or galactic bars, gaps in their stellar streams provide an ideal test case for evidence of interactions with dark matter subhalos.

description: We obtained new Fabry-Perot data cubes and derived velocity fields, monochromatic and velocity dispersion maps for 28 galaxies in the Hickson compact groups 37, 40, 47, 49, 54, 56, 68, 79 and 93. We find that one third of the non-barred compact group galaxies have position angle misalignments between the stellar and gaseous components. This and the asymmetric rotation curves are clear signatures of kinematic perturbations, probably due to interactions among compact group galaxies. A comparison between the B-band Tully-Fisher relation for compact group galaxies and that for the GHASP field-galaxy sample shows that, despite the high fraction of compact group galaxies with asymmetric rotation curves, these lie on the Tully-Fisher relation defined by galaxies in less dense environments, although with more scatter. This is in agreement with previous results, but now confirmed for a larger sample of 41 galaxies. We confirm the tendency for compact group galaxies at the low-mass end of the Tully-Fisher relation (HCG 49b, 89d, 96c, 96d and 100c) to have either a magnitude that is too bright for its mass (suggesting brightening by star formation) and/or a low maximum rotational velocity for its luminosity (suggesting tidal stripping). These galaxies are outside the Tully Fisher relation, at the 1 sigma level, even when the minimum acceptable values of inclinations are used to compute their maximum velocities. The inclusion of such galaxies with v<100 km/s in the determination of the zero point and slope of the compact group B-band Tully-Fisher relation would strongly change the fit, making it different from the relation for field galaxies, a fact that has to be kept in mind when studying scaling relations of interacting galaxies, specially at high redshifts.
