description: A simple analytical model is developed to analyze and explain the complex dynamics of the multi-peak modulation instability spectrum observed in dispersion oscillating optical fibers [M. Droques et al., 37, 4832-4834 Opt. Lett., (2012)]. We provide a simple expression for the local parametric gain which shows that each of the multiple spectral components grows thanks to a quasi-phase-matching mechanism due to the periodicity of the waveguide parameters, in good agreement with numerical simulations and experiments. This simplified model is also successfully used to tailor the multi-peak modulation instability spectrum shape. These theoretical predictions are confirmed by experiments.

description: Recently the teleparallel Lagrangian density described by the torsion scalar T has been extended to a function of T. The $f(T)$ modified teleparallel gravity has been proposed as the natural gravitational alternative for dark energy to explain the late time acceleration of the universe. In order to reconstruct the function $f(T)$ by demanding a background $Λ$CDM cosmology we assume that, (i) the background cosmic history provided by the flat $Λ$CDM (the radiation ere with $ω_{eff}=1/3$, matter and de Sitter eras with $ω_{eff}=0$ and $ω_{eff}=-1$, respectively) (ii) the radiation dominate in the radiation era with $Ω_{0r}=1$ and the matter dominate during the matter phases when $Ω_{0m}=1$. We find the cosmological dynamical system which can obey the $Λ$CDM cosmic history. In each era, we find a critical lines that, the radiation dominated and the matter dominated are one points of them in the radiation and matter phases, respectively. Also, we drive the cosmologically viability condition for these models. We investigate the stability condition with respect to the homogeneous scalar perturbations in each era and we obtain the stability conditions for the fixed points in each eras. Finally, we reconstruct the function $f(T)$ which mimics cosmic expansion history.

description: Aerogels can bridge the nanoscopic to the macroscopic world. One physical phenomenon typically limited to the nanoscopic world is the occurrence of localized surface plasmon resonances (LSPRs), which are observed in conductive nanoparticles. Once brought into close contact, assemblies or superstructures of these nanoparticles often lose their plasmonic properties in the transition stage towards the bulk material. Therefore, LSPRs are typically not observed in macroscopic objects. The present work aims at voluminous nanoparticle-based aerogels with optical properties close to that of the initial colloidal solution and the possibility to manipulate the final plasmonic properties by bringing the particles into defined distances. In detail, Ag nanocrystals with silica shells ranging from 0 to 12 nm are employed as building blocks, which are assembled from their solution into macroscopic three-dimensional superstructures by freezing and subsequent lyophilization. These cryogelated aerogels are synthesized as monoliths and thin films in which the Ag nanocrystals are arranged in defined distances according to their silica shell. The resulting aerogels exhibit plasmonic properties ranging from a behavior similar to that of the building blocks for the thickest shell to a heavily distorted behavior for bare Ag nanocrystals.

description: In order to investigate the coupling between the degrees of alignment of elongated particles in binary nematic dispersions, surfactant stabilized single-wall carbon nanotubes (CNTs) have been added to nematic suspensions of colloidal rodlike viruses in aqueous solution.We have independently measured the orientational order parameter of both components of the guest-host system by means of polarized Raman spectroscopy and by optical birefringence, respectively. Our system allows us therefore to probe the regime where the guest particles (CNTs) are shorter and thinner than the fd virus host particles. We show that the degree of order of the CNTs is systematically smaller than that of the fd virus particles for the whole nematic range. These measurements are in good agreement with predictions of an Onsager-type second-viral theory, which explicitly includes the flexibility of the virus particles, and the polydispersity of the CNTs.

The temperature dependence of the upper critical magnetic field Hc2(T) relevant to EFKA is accounted for by the Pauli model including an anisotropic Pauli paramagnetic contribution (μ_BHp=114 T for H//ab and 86 T for H//c). This is also the case of KFS1 and KFS2 for H//ab whereas a significant upward curvature, accounted for by a two-gap model, is observed for H//c. Despite the presence of antiferromagnetic lattice order within the superconducting state of the studied compounds, no influence of magnetic ordering on the temperature dependence of Hc2(T) is observed.

description: Glacial dynamics are a critically important processes that needs to be studied in order to accurately predict changes in sea level rise as future climate forcing becomes more prominent. In this study, five glacial outlets were measured in a thirty-year time series analysis from 1990 to 2022 in the Sulzberger Ice Shelf located in West Antarctica. While this ice sheet is located in a highly fluctuating region of Antarctic experiencing high mass loss, the Sulzberger Ice Shelf is found to be relatively stable, experiencing both advancing and retreating events, however since 2016, all glacial outlets in the region have been experiencing a retreat of the terminus position. When comparing two ice velocity datasets; NASA’s ITS_LIVE using optical satellite imagery and NASA’s MEaSUREs using a collection of satellite radar and laser altimeters, found that while both measurements followed similar patterns, the optical dataset using feature tracking algorithms consistently measured velocities at higher magnitudes. When analysing the ice velocity from 2001 to 2018, the Sulzberger Ice Shelf appears relatively stable. In a thirty year time series analysis of ice thickness from 1992 to 2020, five out of the seven locations studied within the ice sheet appear to be thinning.

description: In this work we perform an ab-initio study of an ideal two-dimensional sample of 4He atoms, a model for 4He films adsorbed on several kinds of substrates. Starting from a realistic hamiltonian we face the microscopic study of the excitation phonon-roton spectrum of the system at zero temperature. Our approach relies on Path Integral Ground State Monte Carlo projection methods, allowing to evaluate exactly the dynamical density correlation functions in imaginary time, and this gives access to the dynamical structure factor of the system S(q,omega), containing information about the excitation spectrum E(q), resulting in sharp peaks in S(q,omega). The actual evaluation of S(q,omega) requires the inversion of the Laplace transform in ill-posed conditions, which we face via the Genetic Inversion via Falsification of Theories technique. We explore the full density range from the region of spinodal decomposition to the freezing density, i.e. 0.0321 A^-2 - 0.0658 A^-2. In particular we follow the density dependence of the excitation spectrum, focusing on the low wave--vector behavior of E(q), the roton dispersion, the strength of single quasi--particle peak, Z(q), and the static density response function, chi(q). As the density increases, the dispersion E(q) at low wave--vector changes from a super-linear (anomalous dispersion) trend to a sub-linear (normal dispersion) one, anticipating the crystallization of the system; at the same time the maxon-roton structure, which is barely visible at low density, becomes well developed at high densities and the roton wave vector has a strong density dependence. Connection is made with recent inelastic neutron scattering results from highly ordered silica nanopores partially filled with 4He.

description: Along a long-term ecosystem development gradient, soil nutrient contents and mineralogical properties change, therefore probably altering soil microbial communities. However, knowledge about the dynamics of soil microbial communities during long-term ecosystem development including progressive and retrogressive stages is limited, especially in mineral soils. Therefore, microbial abundances (quantitative PCR) and community composition (pyrosequencing) as well as their controlling soil properties were investigated in soil depth profiles along the 120,000 years old Franz Josef chronosequence (New Zealand). Additionally, in a microcosm incubation experiment the effects of particular soil properties, i.e., soil age, soil organic matter fraction (mineral-associated vs. particulate), O2 status, and carbon and phosphorus additions, on microbial abundances (quantitative PCR) and community patterns (T-RFLP) were analyzed. The archaeal to bacterial abundance ratio not only increased with soil depth but also with soil age along the chronosequence, coinciding with mineralogical changes and increasing phosphorus limitation. Results of the incubation experiment indicated that archaeal abundances were less impacted by the tested soil parameters compared to Bacteria suggesting that Archaea may better cope with mineral-induced substrate restrictions in subsoils and older soils. Instead, archaeal communities showed a soil age-related compositional shift with the Bathyarchaeota, that were frequently detected in nutrient-poor, low-energy environments, being dominant at the oldest site. However, bacterial communities remained stable with ongoing soil development. In contrast to the abundances, the archaeal compositional shift was associated with the mineralogical gradient. Our study revealed, that archaeal and bacterial communities in whole soil profiles are differently affected by long-term soil development with archaeal communities probably being better adapted to subsoil conditions, especially in nutrient-depleted old soils.

description: Aluminium (Al) toxicity and drought are two major factors limiting common bean (Phaseolus vulgaris) production in the tropics. Short-term effects of Al toxicity and drought stress on root growth in acid, Al-toxic soil were studied, with special emphasis on Al-drought interaction in the root apex. Root elongation was inhibited by both Al and drought. Combined stresses resulted in a more severe inhibition of root elongation than either stress alone. This result was different from the alleviation of Al toxicity by osmotic stress (-0.60 MPa polyethylene glycol) in hydroponics. However, drought reduced the impact of Al on the root tip, as indicated by the reduction of Al-induced callose formation and MATE expression. Combined Al and drought stress enhanced up-regulation of ACCO expression and synthesis of zeatin riboside, reduced drought-enhanced abscisic acid (ABA) concentration, and expression of NCED involved in ABA biosynthesis and the transcription factors bZIP and MYB, thus affecting the regulation of ABA-dependent genes (SUS, PvLEA18, KS-DHN, and LTP) in root tips. The results provide circumstantial evidence that in soil, drought alleviates Al injury, but Al renders the root apex more drought-sensitive, particularly by impacting the gene regulatory network involved in ABA signal transduction and cross-talk with other phytohormones necessary for maintaining root growth under drought.
A GIS study to determine the potential for Lined Hard Rock Cavern Hydrogen Storage in Northwest Scotland

description: The geological storage of hydrogen in lined rock caverns is a relatively novel concept which has been tested and demonstrated successfully through projects in Sweden like Skallen and HYBRIT. This project investigates suitable locations in the Northwest of Scotland to construct LRCs for hydrogen storage, along with integrating the storage with nearby wind farms with high energy curtailment output to reduce wastage of energy and utilise it effectively. An area with competent rock was studied to demonstrate how a hydrogen storage facility in an LRC would be planned through various screening methods using ArcGIS Pro. The values of the hydrogen capacity estimates of the facility were 37843 m3(single cavern), 49195900 m3(cavern system), 692754 kg (overall system mass) and 27.29 GWh (energy capacity of the system). This methodology can be applied to other areas in Scotland where salt and porous formations are absent, taking into account the curtailed renewable energy in the country, and storing energy in enormous amounts to minimise the impact of energy generation and help achieve Scotland and the UK its net zero targets sooner.

description: China has experienced rapid economic growth and monumental social transition. Meanwhile, mental health issues are troubling Chinese citizens in recent decades, and individual anxiety has become universal that lead to societal anxiety, while several risk factors at individual level are known to cause depression or anxiety disorder, whether and how socioecological factors have impacted on depression or anxiety need to be further verified. This study established a Depression and Anxiety Index scraped by the Baidu Search Index platform to assess the mental well-being across prefecture-level cities in China in 2011, 2015, and 2019, and explored city income-related mental health inequality measured by slope indices of inequality (SII), then examined the socioeconomic and environmental factors of depression and anxiety at regional level examined by multilevel model. The result showed that Depression and Anxiety Index showed an increasing trend from 2011 to 2019. Urban disposable income leads to mental health inequality across China. Furthermore, economic development level concerning GDP, urbanization rate, housing price would exacerbate mental health at the city level.

Our method can therefore serve to measure the quantum efficiency of fluorophores. Application of our technique to NV defects in diamond nanocrystals shows that their quantum yield can significantly differ from unity. Relying on a lateral scanning mechanism with shear-force probe-sample distance control our technique is straightforwardly implemented in most state-of-the-art near-field microscopes.

description: Analysis of gene expression is one of the major ways to better understand plant reactions to changes in environmental conditions. The comparison of many different factors influencing plant growth challenges the gene expression analysis for specific gene-targeted experiments, especially with regard to the choice of suitable reference genes. The aim of this study is to compare expression results obtained by Northern blot, semi-quantitative PCR and RT-qPCR, and to identify a reliable set of reference genes for oilseed rape (Brassica napus L.) suitable for comparing gene expression under complex experimental conditions. We investigated the influence of several factors such as sulfur deficiency, different time points during the day, varying light conditions, and their interaction on gene expression in oilseed rape plants. The expression of selected reference genes was indeed influenced under these conditions in different ways. Therefore, a recently developed algorithm, called GrayNorm, was applied to validate a set of reference genes for normalizing results obtained by Northern blot analysis. After careful comparison of the three methods mentioned above, Northern blot analysis seems to be a reliable and cost-effective alternative for gene expression analysis under a complex growth regime. For using this method in a quantitative way a number of references was validated revealing that for our experiment a set of three references provides an appropriate normalization. Semi-quantitative PCR was prone to many handling errors and difficult to control while RT-qPCR was very sensitive to expression fluctuations of the reference genes.

description: We consider an extension of the standard model in which a singlet fermionic particle, to serve as cold dark matter, and a singlet Higgs are added. We perform a reanalysis on the free parameters. In particular, demanding a correct relic abundance of dark matter, we derive and plot the coupling of the singlet fermion with the singlet Higgs, $g_s$, versus the dark matter mass. We analytically compute the pair annihilation cross section of singlet fermionic dark matter into two photons. The thermally averaged of this cross section is calculated for wide range of energies and plotted versus dark matter mass using $g_s$ consistent with the relic abundance condition. We also compare our results with the Fermi-Lat observations.

Functional characterization of ClC-K/barttin complexes of different stoichiometries

description: ClC-K chloride channels contribute to salt reabsorption in the kidney and to potassium secretion into the endolymph in the inner ear. They build homodimers with each α-subunit possessing its own conducting protopore. Each protopore is regulated by an individual fast gate, while a common slow gate opens and closes both protopores together. Barttin is the accessory β-subunit of ClC-K channels and affects their expression, subcellular localization and gating properties. Co-immunoprecipitations indicate binding of barttin to B- and J-helices of ClC-K α-subunits assuming a 1:2 α:β-subunit stoichiometry for one protopore. However, functional consequences of varying stoichiometry between both subunits are still unknown. To investigate effects of different subunit stoichiometries on channel function, barttin molecules were covalently linked to hClC-Ka or rClC-K1 in a 1:1, 1:2 and 2:1 α:β-subunit ratio. These concatamers were expressed in HEK293T and MDCKII cells and the impact of these compositions on expression, trafficking and channel gating was analyzed using biochemical methods, confocal microscopy and patch clamp technique. We found that one β- per one α-subunit is sufficient for i) proper transport of the channel to the plasma membrane, ii) hClC-Ka channel activation and iii) constitutive slow gate opening of hClC-Ka and rClC-K1. Two β-subunits per one α-subunit additionally open the fast gate of both orthologous channels constitutively. Therefore, a 1:2 α:β-subunit stoichiometry per protopore allows a complete, functional activation of ClC-K channels. Furthermore, palmitoylation-deficient barttin mutants were incorporated in concatamers with different α:β-subunit ratios to study the impact of barttin palmitoylation on channel properties. We here confirm that barttin palmitoylation is not necessary for channel trafficking but for hClC-Ka activation. Co-expression of WT barttin opens the channel, indicating a dynamic exchange of barttin molecules at their binding sites. Palmitoylation is not necessary for barttin to open the rClC-K1 slow gate constitutively but it is essential for constitutive opening of the rClC-K1 fast gate. In further approaches such concatamers might be used to elucidate functional stoichiometries and consequences of disease causing mutations not only for ClC-K/barttin complexes but also for other protein interaction partners.

description: Based on the non-relativistic Coulomb model within which the matter is a system of interacting electrons and nuclei, using the quantum field theory and linear response theory methods, opportunity for the existence of the second critical point in expanded metals, which is directly related to the metal--nonmetal transition, predicted by Landau and Zeldovitch, is theoretically justified. It is shown that the matter at the second critical point is in the state of true dielectric with zero static conductivity. The results obtained are in agreement with recent experiments for expanded metals. The existence of the second critical point is caused by the initial multi-component nature of the matter consisting of electrons and nuclei and the long-range character of the Coulomb interaction.

description: To respond to site-specific coastal flooding concerns, it is important to understand sediment movement in addition to overall shoreline change. This report applies GIS data to MIKE modelling software to observe sand transport in Golspie, Scotland, following predicted flooding scenarios made by the Dynamic Coast project. A combination of openly sourced data was adapted for modelling inputs for the MIKE 21/3 Coupled Model and one year of simulated hydrodynamic processes. The shoreline profiles outside of Golspie’s town and beach showed high levels of erosion while the areas outside of Golspie golf course and Loch Fleet nature reserve remained steady, indicating a need for flood mitigation solutions centred around the town and its infrastructure. Sand erosion along Golspie’s coast in model results suggests that sand nourishment could directly benefit Golspie beach, though high wave velocity could remove added sediment more quickly than at other shoreline segments. Open-source data created a functioning model but verification with fieldwork is recommended for future MIKE use. Additionally, wave action recordings and bathymetry data were integral to MIKE model and module creation, and improvements to the quality of either would lead to more accurate model results.

description: This paper extends the consensus framework, widely studied in the literature on distributed computing and control algorithms, to networks of quantum systems. We define consensus situations on the basis of invariance and symmetry properties, finding four different probabilistic generalizations of classical consensus states. We then extend the gossip consensus algorithm to the quantum setting and prove its convergence properties, showing how it converges to symmetric states while preserving the expectation of permutation-invariant global observables.

Generation of DEMs for Channel Change of the River Feshie, Scotland
Creators: name: Liu, Xiaoyang
Publisher: name: The University of Edinburgh
Year: 2023
Subjects: UAV-SfM, Refraction Correction, Sediment Budget, DoD

description: This paper analyzed changes in the morphology of the River Feshie before and after the September 2022 flood using high-resolution DEMs. The DEM of the river channel in June and November 2022 was established by the UAV-SfM method, and the water depth of the submerged area of the channel was corrected by the refraction correction method based on the small angle approximation correction. Corrected DEMs of the two periods were compared to obtain the DEM of Difference (DoD). This DoD was used to monitor the change in the river channel. The results showed that the UAV-SfM method can perform high-resolution and high-precision topography reconstruction of the river channel at the middle scale, and the small-angle approximate refraction correction method can improve the water depth accuracy. The DoD result indicated that the River Feshie has sediment deposited in the channel after the flood, and the outcome of this study can feed the flood model for the River Feshie in the future.

description: A Ginzburg-Landau model is used to demonstrate how depletion layers give rise to thickness-dependent ferroelectric properties in thin films. It is shown that free charge layers at the film-electrode interface can result in an internal electric field in the bulk of the film even when no external voltage is applied. At high values of the donor dopant density and small thicknesses, this internal electric field can be strong enough to lead to the formation of a domain pattern. This causes a drop in the remnant polarization; a direct demonstration of the important role free charge plays in thin ferroelectric films.

Assessing ICESat-2’s ability to estimate vertical foliage profile in comparison with ALS derived waveform LiDAR for forest management
Creators: name: Nalawade, Rutuja
Publisher: name: The University of Edinburgh
Year: 2023
Subjects: ICESat-2, Canopy Gap Probability, Plant Area Volume Density, Vertical Foliage Profile, GediSimulator

description: One-third of Earth’s land is covered by forest ecosystems, it immensely contributes to the global carbon budget. The functions and internal physiological processes of 3D structure of canopy also plays a key role in carbon dynamic. To increase the understanding of these processes and their contribution, the accurate measurements are needs to be produced. With The Spaceborne platform like ICESat-2 (The Ice, Cloud, and land Elevation Satellite-2) it is now possible to take the measurements of the three-dimensional structure and on the large landscape scales. Here, we evaluate the ability pf ICEsat-2 in deriving vertical foliage profile, in comparison with vertical foliage profile derived from simulated waveforms using ALS. This study uses (GORT) model to calculate PAVD, using gap fraction. The waveforms from ALS are simulated using Gedisimulator.The study further compares the PAVD from both using error matrix. The results do not show a great agreement between the PAVD values, but it gives the insights into the further parameters that needs to be studies and quantified for the increasing the accuracy in PAVD measurements from spaceborne Lidar. The one parameter, canopy and ground reflectance ratio that affects estimates of PAVD have been used in variation to understand the sensitivity of PAVD to the canopy and ground reflectance ratio. Canopy and ground reflectance ratio does affect the PAVD estimates but it cannot alone explain the error in the estimates. This research concludes with suggestions for further research of the PAVD estimation on different landscapes, terrain and vegetation could provide a valuable information and the variability of essential parameters of the PAVD estimation model, and this might increase the accuracy of PAVD estimation from ATL08 product of ICEsat-2.
title: Imagineering America: Disney's View of the USA in its Theme Parks
Creators: name: Weaver, Emily Michelle

description: One of the largest, and most influential entertainment companies, the Walt Disney Company has effectively created its own 'Disney's America' which is represented through its theme parks by producing an immersive experience for guests in both the past and future. With the influential power of the Disney company, they are able to form and present their own vision of America, through the various attractions and architectural designs which create an immersive experience. What began as simply Walt Disney's visions of America through his fascination with the past and promise of the future, has become corporate controlled, with Disney controlling the perceptions of America through the theme parks through the use and presentation of a Disney history and future within the parks. Through the Disney theme parks, a 'Disney's America' of both the past and future is created. These representations of both American history and the future are typically Disneyfied, representing the Disney vision of both the past and future by altering perceptions of America to fit the typical Disney image of family-friendly fun and happiness. A sense of Disney history is created through Disney's representations of the past which is found within both three lands at The Magic Kingdom: Main Street USA, Frontierland and Liberty Square, and the failed planned Disney history theme park. With the company providing representations and recreations of history which are edited, solely positive and idealised versions, history is altered within this vision of America. The darker, less appealing aspects of American history are typically excluded from this Disney vision to ensure only a positive version of America's past is represented. The vision of the Disney future is presented through Tomorrowland, Walt Disney's original plan for a new community of tomorrow and the Disney theme park, Epcot. These present a future filled with optimism and advancements, working towards creating a better, improved future. There are multiple visions of the Disney future: the fantasy future of Tomorrowland, Walt Disney's personal vision and the vision of the Disney company itself. These are similar in that they represent a future of advancement and optimism with negativity removed, still fitting with the Disney image. The 'Disney's America' is created through the immersive experiences provided throughout the Disney theme parks where guests first-hand experience the Disney vision of the past and future, entering the world of a Disney's America. Disney creates these experiences through the attractions and architectural design of the parks which effectively result in enjoyable, unforgettable guest experiences. Disney has become an integral part of American culture and America has become Disney.

Subjects: CryoSat-2; Swath Processing; Interferometry; Grounding Line; Grounding Zone; Amundsen Sea Embayment; Thwaites; Surface Elevation Change; Cryosphere; Antarctica

description: Ongoing loss of ice mass in the Amundsen Sea Embayment of West Antarctica has the potential to contribute significantly to sea level rise. Ice grounding lines are important in understanding the glacial dynamics driving these changes, and satellite remote sensing methods have provided information about grounding line location. However, limitations of existing methods for identifying grounding zone features include difficulty mapping in regions with fast-moving ice, where grounding line retreat has been most pronounced. This study aimed to demonstrate a novel approach for mapping grounding zone features that is effective for fast flowing ice where thinning is present. Elevation changes from CryoSat-2 swath-processed interferometric mode data from April 2010-January 2022 were examined to explore grounding zone dynamics in the Amundsen Sea Embayment. Grounding zone boundaries mapped using 10-year elevation change data were in general agreement with existing grounding zone datasets, and grounding zones mapped from 5-year elevation change data provided insights about grounding zone retreat that guided further analyses. Pixel-scale timeseries analyses of monthly elevation revealed two main periods in which ice transitioned from grounded to floating, January to April 2014 and July to October 2016, suggesting grounding line retreat. The spatial patterns of this transition match those of existing grounding zone datasets. Onset of accelerated ice thinning was also identified in two periods: October 2012-January 2014 and January 2017-January 2018. These investigations demonstrate that rate of elevation change from swath-processed CryoSat-2 data provides useful information in contribution to grounding zone investigations, and provide a foundation for further refinement.
