description: Forests are important in sequestering CO2 and therefore play a significant role in climate change. However, the CO2 cycle is conditioned by drought events that alter the rate of photosynthesis, which is the principal physiological action of plants in transforming CO2 into biological energy. This study applied recurrence quantification analysis (RQA) to describe the evolution of photosynthesis-related indices to highlight disturbance alterations produced by the Atlantic Multidecadal Oscillation (AMO, years 2005 and 2010) and the El Niño-Southern Oscillation (ENSO, year 2015) in the Amazon forest. The analysis was carried out using Moderate Resolution Imaging Spectroradiometer (MODIS) images to build time series of the enhanced vegetation index (EVI), the normalized difference water index (NDWI), and the land surface temperature (LST) covering the period 2001–2018. The results did not show significant variations produced by AMO throughout the study area, while a disruption due to the global warming phase linked to the extreme ENSO event occurred, and the forest was able to recover. In addition, spatial differences in the response of the forest to the ENSO event were found. These findings show that the application of RQA to the time series of vegetation indices supports the evaluation of the forest ecosystem response to disruptive events. This approach provides information on the capacity of the forest to recover after a disruptive event and, therefore is useful to estimate the resilience of this particular ecosystem.

description: Abstract

Objective: The study aimed to measure the transient axial length (AXL) changes after short-term exposure to blue light before and after hyperopic defocus. Methodology: An interventional study design (quasi-experimental pre and post-interventional design) was conducted at Al-Shifa Trust Eye Hospital among optometry students using a non-probability judgmental sampling technique. Visual acuity was measured with LogMAR, and refractive status was determined with a Retinoscope. Blue light exposure was administered using a Blue Laser Pointer emitting a 405nm wavelength. Hyperopic defocus was induced using a -3.00DS lens in a trial frame. The IOL Master Zeiss 700 was used to measure the AXL. Data were entered and analyzed through online web-based software, Data tab. Results: A total of 30 subjects, including 06 (20%) males and 24 (80%) females, with a mean age of 20.67 ± 0.96, participated in the study. Comparing Pre-defocus Axial length (PDAXL) and After Defocus Axial length (ADAXL) following 30 seconds (23.2 ± 0.69, 23.19 ± 0.68, p 0.006), 60 seconds (23.2 ± 0.68, 23.2 ± 0.68, p 0.056), and 90 seconds (23.2 ± 0.69, 23.2 ± 0.69, p 0.002) of exposure to blue light, a statistically significant difference was observed among the 30-second and 90-second exposure groups (p 0.006 and p 0.002, respectively), but not among the 60-second group (p 0.056). Conclusion: The study concludes that short-wavelength exposure and hyperopic defocus together cause axial length shortening, which could be employed to manage myopia progression.

description: We present an analysis of Li abundances in low mass stars (LMS) during the Red Giant Branch (RGB) and Asymptotic Giant Branch (AGB) stages, based on a new determination of their luminosities and evolutionary status. By applying recently suggested models for extra-mixing, induced by magnetic buoyancy, we show that both Li-rich and Li-poor stars can be accounted for. The simplest scenario implies the development of fast instabilities on the RGB, where Li is produced. When the fields increase in strength, buoyancy slows down and Li is destroyed. 3He is consumed, at variable rates. The process continues on the AGB, where however moderate mass circulation rates have little effect on Li due to the short time available. O-rich and C-rich stars show different histories of Li production/destruction, possibly indicative of different masses. More complex transport schemes are allowed by magnetic buoyancy, with larger effects on Li, but most normal LMS seem to show only the range of Li variation discussed here.

Props for social discourse

Publisher: name: University Of Tasmania
Year: 2023

description: This research project investigates the role of seating in rural and urban public spaces. It incorporates references to both past and contemporary societies and has been developed as a series of Props for Social Discourse. The result has been the development of pieces of furniture that began with a narrative response to thinking about my life, growing up and living on the North West Coast of Tasmania. On one level, the resulting works tell a story about how country folk or city folk converse with one another in relatively relaxed social situations. The narrative depicts this Australian discourse both with humour and with a more serious cultural intention, one which is focussed upon how furniture might influence social intercourse. Running parallel to this investigation, on a formal level, I have explored the integration of metals and leather. I have woven these two materials together to create a unity. The works challenge the traditional use of these materials, especially in the manner that they have been utilised jointly to date. The starting point for these Props for Social Discourse was my observation of the manner in which rural people from my district placed their bodies in particular positions when participating in social discourse. This led me to develop the theme of the Leaning Post which, in its various manifestations, is intended to be introduced into public social spaces. These works are directed towards bars, cafes, clubs and meeting places. The public spaces are specific to people who rest and have social discourse whilst their body is in a vertical, semi-standing position. Another body of work in these Props for Social Discourse is a range of seating which has been formulated through my investigations of the positions strangers place themselves in while sitting in public spaces. I have developed seating where the sitting positions are separated in order to create a comfortable personal resting place. The seating also addresses the direction that people need to face whilst sitting. This directional position changes constantly as strangers rest together within public spaces. It is my intention that these Props for Social Discourse have an immediate tactile response with the body. This feeling is visually enhanced where I have integrated metals and leather. I have paralleled these responses with the sexual ones we encounter when relating body skin with sheer fabric or with see-through metal fabric that is presently evident within contemporary body adornment. The outcome has been the melding of these responses within the Props. This development has allowed me to produce larger scale pieces for public spaces which give people the opportunity to respond to the tactility of the form, in both a sensual and sensory way. It is intended that their regional source is also emphasized. By drawing upon my past regional imagery and transforming them into usable contemporary Props, this thesis addresses social interaction in public spaces.

description: Disorder modifies the sound-wave excitation spectrum of Bose-Einstein condensates. We consider the classical hydrodynamic limit, where the disorder correlation length is much longer than the condensate healing length. By perturbation theory, we compute the phonon lifetime and correction to the speed of sound. This correction is found to be negative in all dimensions, with universal asymptotics for smooth correlations. Considering in detail optical speckle potentials, we find a quite rich intermediate structure. This has consequences for the average density of states, particularly in one dimension, where we find a "boson dip" next to a sharp "boson peak" as function of frequency. In one dimension, our prediction is verified in detail by a numerical integration of the Gross-Pitaevskii equation.

description: The tripartite motif (TRIM) protein family members have been implicated in a multitude of physiologies and pathologies in different tissues. With diverse functions in cellular processes including regulation of signaling pathways, protein degradation, and transcriptional control, the impact of TRIM dysregulation can be multifaceted and complex. Here, we focus on the cellular and molecular roles of TRIMs identified in the brain in the context of a selection of pathologies including cancer and neurodegeneration. By examining each disease in parallel with described roles in brain development, we aim to highlight fundamental common mechanisms employed by TRIM proteins and identify opportunities for therapeutic intervention.

description: Fifty archival radio observations of the supergiant binary Cyg OB2 #5 using the Very Large Array over 20 years are re-examined to determine the location and character of the previously detected variable radio emission. The radio emission from the system consists of a primary component that is associated with the binary, and a non-thermal source (NE) that has been ascribed to a wind-collision region (WCR) between the stellar winds of the binary and that of a B-type star (Star D) to the NE. NE shows no evidence of variation in 23 epochs where it is resolved separately from the primary radio component, demonstrating that the variable emission arises in the primary. Since NE is non-variable, the radio flux from the primary can now be well determined for the first time, most especially in observations that do not resolve both the primary and NE components. The variable radio emission from the primary has a period of 6.7+/-0.3 years which is described by a simple model of a non-thermal source orbiting within the stellar wind envelope of the binary. Such a model implies the presence of a third, unresolved stellar companion (Star C) orbiting the 6.6-day binary with a period of 6.7 years. The variable non-thermal emission arises from either a WCR between Star C and the binary system, or possibly from Star C directly. The model gives a mass-loss rate of 3.4 x 10^{-5} solar mass/yr for Cyg OB2 #5, unusually high for an Of supergiant and comparable to that of WR stars, and consistent with an unusually strong He I 1.083-micron emission line, also redolent of WR stars. An examination of radial velocity observations suggests reflex motion of the binary due to Star C. The natures of NE and Star D are also examined. (abridged)

description: In the current document we present the integration strategy of TheFSM Platform which includes the development, testing and deployment strategy for TheFSM technical solution. We focus the on methodology on both component and platform level. Unit testing is utilized to automate testing as much as possible, while we carefully follow well-established industry standards and methodologies in our approach. We provide examples of unit tests which test the internal functionality of components and their compliance with the specifications. Additionally, integration tests are provisioned in order to assure the interoperability between components. As more use cases are covered by the platform, these tests will evolve, adapt and carefully cover the newly added functionality. Moreover, we describe issue tracking and the dockerization process we follow during development. The current document provides a) the approach we follow in development regarding both the overall project and within component level, b) the technical verification of our pipeline. We define how verification is guaranteed via unit and integration testing, thoroughly describing the unit testing process and c) the technical evaluation, where we define metrics and KPIs relevant to the project and we provide analytical tables which include our performance against the relevant metrics.

description: The absolute visual magnitude as function of the observed colour (B-V), also named Hertzsprung-Russell diagram can be described through five equations; that in presence of calibrated stars means eight constants. The developed framework allows to deduce the remaining physical parameters that are mass, radius and luminosity. This new technique is applied to the first 10 pc, the first 50 pc, the Hyades and to the determination of the distance of a cluster. The case of the white dwarfs is analysed assuming the absence of calibrated data: our equation produces a smaller $χ^2$ in respect to the standard colour-magnitude calibration when applied to the Villanova Catalog of Spectroscopically Identified White Dwarfs. The theoretical basis of the formulae for the colours and the bolometric correction of the stars are clarified through a Taylor expansion in the temperature of the Planck distribution.

description: With the advent of global climate change, heat-tolerance is becoming more and more important to the sustainability of animal husbandry production systems. Previous studies have shown that MYO1A gene associated with pigmentation may be closely related to heat-tolerance in cattle. In this study, a novel missense mutation (NC_037332.1 g.56390345 A > G) was first detected in MYO1A in 891 individuals of 35 cattle breeds, which transformed the amino acid isoleucine into valine. The purpose of this study was to determine the allele frequencies distribution of this locus in Chinese indigenous cattle and to analyze the relationship between this locus and heat-tolerance. Further analysis showed that frequency of wild allele A decreased gradually from northern cattle to southern cattle, whereas frequency of mutant type allele G showed the opposite pattern, which was consistent with the distribution of various climatic conditions of China. Additionally, association analysis was carried out between genotypes and four climatic conditions (annual mean temperature (T), relative humidity (H), temperature-humidity index (THI) and average annual sunshine hours (100-cloudiness) (SR)). Analysis results showed that genotypes were significantly correlated with climatic conditions. Therefore, our results suggest that the novel SNP (rs209559414) is related to heat-tolerance trait of Chinese indigenous cattle.

description: Cold atmospheric plasmas (CAPs) are promising medical tools and are currently applied in dermatology and epithelial cancers. While understanding of the biomedical effects is already substantial, knowledge on the contribution of individual ROS and RNS and the mode of activation of biochemical pathways is insufficient. Especially the formation and transport of short-lived reactive species in liquids remain elusive, a situation shared with other approaches involving redox processes such as photodynamic therapy. Here, the contribution of plasma-generated reactive oxygen species (ROS) in plasma liquid chemistry was determined by labeling these via admixing heavy oxygen 18O2 to the feed gas or by using heavy water H218O as a solvent for the bait molecule. The inclusion of heavy or light oxygen atoms by the labeled ROS into the different cysteine products was determined by mass spectrometry. While products like cysteine sulfonic acid incorporated nearly exclusively gas phase-derived oxygen species (atomic oxygen and/or singlet oxygen), a significant contribution of liquid phase-derived species (OH radicals) was observed for cysteine-S-sulfonate. The role, origin, and reaction mechanisms of short-lived species, namely hydroxyl radicals, singlet oxygen, and atomic oxygen, are discussed. Interactions of these species both with the target cysteine molecule as well as the interphase and the liquid bulk are taken into consideration to shed light onto several reaction pathways resulting in observed isotopic oxygen incorporation. These studies give valuable insight into underlying plasma–liquid interaction processes and are a first step to understand these interaction processes between the gas and liquid phase on a molecular level.
Selective excitations of trasverse vibrational modes of a carbon nanotube through a "shuttle-like" electromechanical instability

description: We study the dynamics of transverse oscillations of a suspended carbon nanotube into which current is injected from the tip of a scanning tunneling microscope (STM). In this case the correlations between the displacement of the nanotube and its charge state, determined by the position-dependent electron tunneling rate, can lead to a "shuttle-like" instability for the transverse vibrational modes. We find that selective excitation of a specific mode can be achieved by an accurate positioning of the STM tip. This result suggests a feasible way to control the dynamics of this nano-electromechanical system (NEMS) based on the "shuttle instability".

description: Noble metal catalysts possess outstanding catalytic behaviors in organic reactions, photocatalysis, electrocatalysis and many other applications. Peptide fibrils are used for the controllable nanostructuring of metal nanoparticles with specific sizes, shapes and high-surface area structures. The degradation of these fibrils with O2-plasma yields interconnected networks of nanoparticles, similar to metallic nanowires. Herein, platinum nanoparticles (Pt-NPs) were synthesized by reduction using VUV excimer radiation. The particle size was characterized by dynamic light scattering (DLS). Due to agglomeration, the metal nanoparticles were stabilized using poly(vinyl pyrrolidone) (PVP) and the same synthesis procedure. The influence of the polymer PVP molecular weight (Mwt), PVP concentration (Cp) and VUV irradiation time on platinum nanoparticle size was investigated. Small (2–3 nm) Pt-NPs are formed in the case of PVP with Mwt = 10 000 g mol−1. With increasing PVP Mwt, decreasing PVP concentration and shorter irradiation times, larger sized nanoparticles appear. The applicability of templated platinum nanoparticles, both the PVP-stabilized and non-stabilized Pt-NPs, immobilized via electrostatic interactions on the solid phase-synthesized aniline-GGAAKLVFF (AFP) peptide fibrils was investigated to serve as possible electrode material. The plasma treatment of the nanoparticle-fibril-assemblies was also studied as a novel technique. The Pt-NPs-AFP fibrils and the PVP-stabilized-Pt-NPs-AFP fibrils nanohybrids were employed to modify electrodes and then subjected to O2-plasma treatment. These O2-plasma treated/modified electrodes exhibited high electrocatalytic activities towards oxygen reduction in cyclic voltammetry measurements. Thus, the aforementioned nanocomposites hold great potential for polymer electrolyte fuel cells and other electrochemical applications in miniature devices and microfluidic chips.

description: We present the results of a systematic search for large-scale spectroscopic variability in apparently single Wolf-Rayet stars brighter than ~12.5. In this first paper we characterize the various forms of variability detected and distinguish several separate groups. For each star in our sample, we obtained 4-5 high-resolution spectra with a signal-to-noise ratio ~100. Our ultimate goal is to identify new candidates presenting variability that potentially comes from Co-rotating Interaction Regions (CIR). Out of a sample of 25 stars, 10 were found to display large-scale changes of which 4 are of CIR-type (WR1, WR115, WR120 and WR134). The star WR134 was already known to show such changes from previous studies. Three WN8 stars present a different type of large-scale variability and we believe deserve a group of their own. Also, all three WC9d stars in our sample present large-scale variability, but it remains to be checked if these are binaries, as many dust-making WR stars are double. Finally, of the remaining stars, 10 were found to show small-amplitude spectral changes which we attribute to normal line-profile variability due to inhomogeneities in the wind, and 5 were found to show no spectral variability, as far as can be concluded from the data in hand. Follow-up studies are required to identify potential periods for our candidates showing CIR-type changes and eventually estimate a rotation rate for these WR stars.

description: Quantitative Biology at Community Colleges (QB@CC) is a National Science Foundation (NSF) supported project that received funding in 2019. The long-term goal of QB@CC is to drive the disciplinary expectation that all biology courses should significantly enhance student's quantitative skills. QB@CC does this by providing educational materials and professional development for faculty. The network will generate a large collection of Open Education Resources (OERs) that may be used by anyone, and professional development programming will be designed to address many of the challenges in teaching quantitative skills. Although this network focuses on community college faculty, most of the materials generated will be appropriate for lower level biology courses in four-year institutions.

description: Interpretations of indirect searches for dark matter (DM) require theoretical predictions for the annihilation or decay rates of DM into stable particles of the standard model. These predictions include usually only final states accessible as lowest order tree-level processes, with electromagnetic bremsstrahlung and the loop-suppressed two gamma-ray line as exceptions. We show that this restriction may lead to severely biased results for DM tailored to produce only leptons in final states and with mass in the TeV range. For such models, unavoidable electroweak bremsstrahlung of Z and W-bosons has a significant influence both on the branching ratio and the spectral shape of the final state particles. We work out the consequences for two situations: Firstly, the idealized case where DM annihilates at tree level with 100% branching ratio into neutrinos. For a given cross section, this leads eventually to "minimal yields" of photons, electrons, positrons and antiprotons. Secondly, the case where the only allowed two-body final states are electrons. The latter case is typical of models aimed at fitting cosmic ray e^- and e^+ data. We find that the multimessenger signatures of such models can be significantly modified with respect to results presented in the literature.

The interaction of non-metallic superalkalis such as F2H3, O2H5, and N2H7 with CO2 has been systematically explored using ab initio MP2/6-311++G(d,p) method. We have studied the structural isomers of the resulting superalkali-CO2 complexes and their relative stabilities. We have analyzed their partial charge, spin density, and singly-occupied molecular orbitals’ energy, which reveal the relative strength and charge transfer due to the interaction of CO2 with superalkalis. We notice that this interaction leads to the reduction of CO2, as the structure of CO2 moiety in superalkali-CO2 complexes is bent due to electron transfer from superalkalis. Thus, this study should provide some interesting results on the single-electron reduction of CO2 by non-metallic compounds.

description: Photoexcitation of internal proton transfer in the tinuvin molecule causes the excitation of some low frequency vibrational modes which oscillate with high amplitudes in a coherent manner over 700 fs. Such effect is observed for the first time applying two color pump/probe measurement with 25 fs pulses. Based on resonance Raman spectra a normal coordinate analysis of the modes is performed. It is shown that the nuclear movement given by the normal vibration of one of the modes serves to open up a barrierfree proton transfer path.

Correlation of microstructure with tensile deformation behaviour in dispersion strengthened aluminum
Creators: name: Surana, Narendra Singh
Publisher: name: University of British Columbia
Year: 2011

description: The tensile behaviour of an A1-1OSb alloy, containing a dispersion of the intermetallic compound A1Sb, has been compared with that of an overaged A1-4Cu alloy in the temperature range of -100 to 200°C. As an aid to the interpretation of the alloy results, pure aluminum has also been examined, over the range of grain size represented by the two alloys. A coarse dispersion of A1Sb was not found to increase the yield strength of aluminum for a given initial grain for subgrain) size. However, the dispersion markedly increased the resistance of aluminum to recovery and recrystallisation, at the same time increasing the true ultimate strength and the uniform elongation. The observed tensile properties of pure aluminum have been explained by a cell formation and migration argument. The tensile deformation behaviour of A1-1OSb and A1-4Cu has been explained in the light of current theories and as an extension of the interpretation of the behaviour of pure aluminum.

description: In this paper, we address the issue of the generation of non-degenerate cross-polarization-entangled photon pairs using type-II periodically poled lithium niobate. We show that, by an appropriate engineering of the quasi-phase-matching grating, it is possible to simultaneously satisfy the conditions for two spontaneous parametric down-conversion processes, namely ordinary pump photon down-conversion to either extraordinary signal and ordinary idler paired photons, or to ordinary signal and extraordinary idler paired photons. In contrast to single type-II phase-matching, these two processes, when enabled together, can lead to the direct production of cross-polarization-entangled state for non degenerate signal and idler wavelengths. Such a scheme should be of great interest in applications requiring polarization-entangled non degenerate paired photons with, for instance, one of the entangled photons at an appropriate wavelength being used for local operation or for quantum storage in an atomic ensemble, and the other one at the typical wavelength of 1550 nm for propagation through an optical fiber.

On correlation functions of operators dual to classical spinning string states

description: We explore how to compute, classically at strong coupling, correlation functions of local operators corresponding to classical spinning string states. The picture we obtain is of `fattened' Witten diagrams, the evaluation of which turns out to be surprisingly subtle and requires a modification of the naive classical action due to a necessary projection onto appropriate wave functions. We examine string solutions which compute the simplest case of a two-point function and reproduce the right scaling with the anomalous dimensions corresponding to the energies of the associated spinning string solutions. We also describe, under some simplifying assumptions, how the spacetime dependence of a conformal three-point correlation function arises in this setup.

description: The photon-neutrino processes $γe^{\pm} \to e^{\pm} ν\bar ν$, $γ\to ν\bar ν$ and $γγ\to ν\bar ν$ are investigated in the presence of a strongly magnetized and dense electron-positron plasma. The amplitudes of the reactions $γe^{\pm} \to e^{\pm} ν\bar ν$ and $γγ\to ν\bar ν$ are obtained. In the case of a cold degenerate plasma contributions of the considering processes to neutrino emissivity are calculated. It is shown that contribution of the process $γγ\to ν\bar ν$ to neutrino emissivity is supressed in comparision with the contributions of the processes $γe^{\pm} \to e^{\pm} ν\bar ν$ and $γ\to ν\bar ν$. The constraint on the magnetic field strength in the magnetar outer crust is obtained.

description: We extract the positron and electron fluxes in the energy range 10 - 100 GeV by combining the recent data from PAMELA and Fermi LAT. The {\it absolute positron and electron} fluxes thus obtained are found to obey the power laws: $E^{-2.65}$ and $E^{-3.06}$ respectively, which can be confirmed by the upcoming data from PAMELA. The positron flux appears to indicate an excess at energies $E\gsim 50$ GeV even if the uncertainty in the secondary positron flux is added to the Galactic positron background. This leaves enough motivation for considering new physics, such as annihilation or decay of dark matter, as the origin of positron excess in the cosmic rays.

Zero-error communication via quantum channels, non-commutative graphs and a quantum Lovasz theta function

description: We study the quantum channel version of Shannon's zero-error capacity problem. Motivated by recent progress on this question, we propose to consider a certain operator space as the quantum generalisation of the adjacency matrix, in terms of which the plain, quantum and entanglement-assisted capacity can be formulated, and for which we show some new basic properties. Most importantly, we define a quantum version of Lovasz' famous theta function, as the norm-completion (or stabilisation) of a "naive" generalisation of theta. We go on to show that this function upper bounds the number of entanglement-assisted zero-error messages, that it is given by a semidefinite programme, whose dual we write down explicitly, and that it is multiplicative with respect to the natural (strong) graph product. We explore various other properties of the new quantity, which reduces to Lovasz' original theta in the classical case, give several applications, and propose to study the operator spaces associated to channels as "non-commutative graphs", using the language of Hilbert modules.

description: It examines the linguistic nuances associated with the terms Cinema, film, movie ormotion picture and how they relate to the aesthetics, entertainment value, and economic aspectsof Chinese cinema. It also discusses the fascinating and tumultuous history of Chinese cinemafrom its inception in the late 19th century until the year 1949. Often considered in two distinct"golden ages," namely the 1930s and the late 1940s, this historical exploration seeks to analyzethe critical junctures and opportunities that shaped the trajectory of Chinese cinema during thisperiod. From its early days as a medium for recording daily events to its evolution into a complexand powerful art form, Chinese cinema mirrored the social, political, and cultural changes of itstime.

description: Neurodevelopmental disorders encompass a spectrum of different conditions with both genetic and environmental etiologies. Although rapid progress has been made in deciphering the genetic landscape of these disorders, in most cases, it remains unclear how mutations undermine neurodevelopmental mechanisms. However, increasing identification of risk genes suggests chromatin remodelling is frequently impacted. For instance, de novo variants encoding the chromatin remodeller CHD4 causes Sifrim-Hitz-Weiss syndrome, which manifests as an overgrowth-intellectual disability syndrome. To further understand Chd4’s role during cortical development, we excised the ATPase domain of Chd4 in the germline or specifically in the developing telencephalon, creating three mouse models. Germline heterozygotes presented a slight decrease in brain weight, cortex area and Ctip2+ cells, with females displaying more overt impairments in learning and memory. Telencephalon-specific conditional heterozygotes exhibited slight changes in white matter, increased repetitive movements and altered social behaviours. Telencephalon-specific conditional knockouts presented with decreased brain size, brain weight, and cortex thickness due to decreased upper layer neurons, and anxiety phenotypes. These data reveal an unexpected complexity in the impacts of Chd4 mutations on neurodevelopmental processes and behaviour.
