description: We have discovered a new domain of optical coherence, and show that it is the third and last member of a previously unreported fundamental triad of coherences. These are unified by our derivation of a parallel triad of coherence constraints that take the form of complementarity relations. We have been able to enter this new coherence domain experimentally and we describe the novel tomographic approach devised for that purpose.

description: According to the Einstein's theory of relativity, the passage of time changes in a gravitational field. On earth, raising a clock by one centimetre increases its tick rate by 1.1 parts in 10$^{18}$, enabling optical clocks to perform precision geodesy. Here, we demonstrate geopotentiometry by determining the height difference of master and slave clocks separated by 15 km with uncertainty of 5 cm. The subharmonic of the master clock is delivered through a telecom fibre to phase-lock and synchronously interrogate the slave clock. This protocol rejects laser noise in the comparison of two clocks, which improves the stability of measuring the gravitational red shift. Such phase-coherently operated clocks facilitate proposals for linking clocks and interferometers. Over half a year, 11 measurements determine the fractional frequency difference between the two clocks to be $1,652.9(5.9)\times 10^{-18}$, or a height difference of 1,516(5) cm, consistent with an independent measurement by levelling and gravimetry. Our system is as a building block of an internet of clocks, consisting of a master and a number of slave clocks, which will provide "quantum benchmarks" that are height references with dynamic response.

Operationalizing EBSA criteria
Good Environmental Status

description: A prerequisite for Planning Sites to develop scenarios and planning options is a robust science base for the prioritisation and zonation of MPA networks by measuring the spatial distribution of existing and newly developed EBSA criteria. MarinePlan will develop under WP2 (i) spatially explicit, quantitative metrics for EBSA criteria that are compatible with ecosystem-based, environmental state indicators (e.g., MSFD), (ii) guidance for the application of these metrics at various spatial scales, and (iii) the quantification of dispersal and movement corridors of different life stages (functional connectivity), biodiversity attributes, and species interactions. MarinePlan will expand on previous approaches to operationalize EBSA criteria to be compatible with biodiversity goals including the target of Good Environmental Status. Assessing the spatial connectivity between MPAs, WP2 will also propose spatially efficient zonation and avoiding competing sea uses where possible. Spatially explicit, quantitative measures of the seven EBSA criteria (uniqueness; special importance for life history stages of species; importance for threatened, endangered or declining species and/or habitats; vulnerability; fragility; sensitivity or slow recovery; biological productivity; biological diversity; naturalness) will be established and quantitatively linked to population- and ecosystem dynamics which, in turn, may affect the capacity to supply marine ecosystem services.

description: Unsustainable agriculture practices are undermining the world's future ability to reliably produce food. Assistance programmes, such as those offered by the Natural Resource Conservation Service (NRCS) of the United States, can increase the uptake of sustainable practices, yet implementation of these alternatives in the US remains discouragingly limited. In this context, we used an interdisciplinary approach involving quantitative and qualitative data to assess the current efficacy of NRCS assistance programmes and identify areas for improvement. To do so, we first analyzed national reports of NRCS expenditures and acres treated over the last 15 years and then distributed an explorative survey to farmers and ranchers throughout Utah state. Our NRCS programme analysis suggested that historical increases in expenditures have been ineffective at increasing the number of acres treated. The survey responses indicated that both financial and non-financial factors were influential in farmer decisions. Farmers that assigned a high importance to sustainable practices were motivated by public perception and environmental stewardship while those that assigned a moderate importance were motivated by the potential return on investment. Overall, participants in NRCS programs reported more positive outcomes than expected by non-participants. We hope the findings from this study can guide future research and inform efforts to improve NRCS assistance programmes in Utah and other regions in the US and elsewhere.

Secure and cost-effective operation of low carbon power systems under multiple uncertainties
Creators: name: O'Malley, Cormac
Publisher: name: Imperial College London
Year: 2023

description: Power system decarbonisation is driving the rapid deployment of renewable energy sources (RES) like wind and solar at the transmission and distribution level. Their differences from the synchronous thermal plants they are displacing make secure and efficient grid operation challenging. Frequency stability is of particular concern due to the current lack of provision of frequency ancillary services like inertia or response from RES generators. Furthermore, the weather dependency of RES generation coupled with the proliferation of distributed energy resources (DER) like small-scale solar or electric vehicles permeates future low-carbon systems with uncertainty under which legacy scheduling methods are inadequate. Overly cautious approaches to this uncertainty can lead to inefficient and expensive systems, whilst naive methods jeopardise system security. This thesis significantly advances the frequency-constrained scheduling literature by developing frameworks that explicitly account for multiple new uncertainties. This is in addition to RES forecast uncertainty which is the exclusive focus of most previous works. The frameworks take the form of convex constraints that are useful in many market and scheduling problems. The constraints equip system operators with tools to explicitly guarantee their preferred level of system security whilst unlocking substantial value from emerging and abundant DERs. A major contribution is to address the exclusion of DERs from the provision of ancillary services due to their intrinsic uncertainty from aggregation. This is done by incorporating the uncertainty into the system frequency dynamics, from which deterministic convex constraints are derived. In addition to managing uncertainty to facilitate emerging DERs to provide legacy frequency services, a novel frequency containment service is designed. The framework allows a small amount of load shedding to assist with frequency containment during high RES low inertia periods. The expected cost of this service is probabilistic as it is proportional to the probability of a contingency occurring. The framework optimally balances the potentially higher expected costs of an outage against the operational cost benefits of lower ancillary service requirements day-to-day. The developed frameworks are applied extensively to several case studies. These validate their security and demonstrate their significant economic and emission-saving benefits.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The study of factors determining the profitability of companies has been given special attention over time in the fields of business research. In this study, a time series data set of National Tobacco Enterprise (Ethiopia) S.C was used for examining the determinants of the Company's profitability employing Ordinary Least Square (OLS) method. For this purpose financial information covering years 1968 – 2015 were collected and analyzed. Return on asset, considered as a measure for profitability, is the dependent variable while firm size, sales growth, expense to revenue ratio, gross margin return on inventory, sales to current asset ratio, and inventory holding period are considered as independent variables. According to the findings, firm size and expense revenue ratio showed statistically significant negative effect on profitability. Whereas, sales growth, gross margin return on inventory and sales to current asset ratios have significant positive effect on profitability. Inventory holding period, however, has positive but insignificant effect on profitability. Key words: Profitability, profitability Determinants, time series data, manufacturing companies

description: We investigated the possibility of using a machine-learning scheme in conjunction with commercial wearable EEG-devices for translating listener's subjective experience of music into scores that can be used for the automated annotation of music in popular on-demand streaming services. Based on the established -neuroscientifically sound- concepts of brainwave frequency bands, activation asymmetry index and cross-frequency-coupling (CFC), we introduce a Brain Computer Interface (BCI) system that automatically assigns a rating score to the listened song. Our research operated in two distinct stages: i) a generic feature engineering stage, in which features from signal-analytics were ranked and selected based on their ability to associate music induced perturbations in brainwaves with listener's appraisal of music. ii) a personalization stage, during which the efficiency of ex- treme learning machines (ELMs) is exploited so as to translate the derived pat- terns into a listener's score. Encouraging experimental results, from a pragmatic use of the system, are presented.

description: When does a diffusing particle reach its target for the first time? This first-passage time (FPT) problem is central to the kinetics of molecular reactions in chemistry and molecular biology. Here we explain the behavior of smooth FPT densities, for which all moments are finite, and demonstrate universal yet generally non-Poissonian long-time asymptotics for a broad variety of transport processes. While Poisson-like asymptotics arise generically in the presence of an effective repulsion in the immediate vicinity of the target, a time-scale separation between direct and reflected indirect trajectories gives rise to a universal proximity effect: Direct paths, heading more or less straight from the point of release to the target, become typical and focused, with a narrow spread of the corresponding first passage times. Conversely, statistically dominant indirect paths exploring the system size tend to be massively dissimilar. The initial distance to the target particularly impacts gene regulatory or competitive stochastic processes, for which often few binding events determine the regulatory outcome. The proximity effect is independent of details of the transport, highlighting the robust character of the FPT features uncovered here.

description: In 4 dimensional Maxwell gauge theory, we study the changes of (Renyi) entangle-ment entropy which are defined by subtracting the entropy for the ground state from the one for the locally excited states generated by acting with the gauge invariant local operators on the state. The changes for the operators which we consider in this paper reflect the electric-magnetic duality. The late-time value of changes can be interpreted in terms of electromagnetic quasi-particles. When the operator constructed of both electric and magnetic fields acts on the ground state, it shows that the operator acts on the late-time structure of quantum entanglement differently from free scalar fields.

description: The Standard Model cannot explain the dominance of matter over anti-matter in our universe. This imbalance indicates undiscovered physics that violates combined CP symmetry. Many extensions to the Standard Model seek to explain the imbalance by predicting the existence of new particles. Vacuum fluctuations of the fields associated with these new particles can interact with known particles and make small modifications to their properties; for example, particles which violate CP symmetry will induce an electric dipole moment of the electron (eEDM). The size of the induced eEDM is dependent on the masses of the new particles and their coupling to the Standard Model. To date, no eEDM has been detected, but increasingly precise measurements probe new physics with higher masses and weaker couplings. Here we present the most precise measurement yet of the eEDM using electrons confined inside molecular ions, subjected to a huge intra-molecular electric field, and evolving coherently for up to 3 s. Our result is consistent with zero and improves on the previous best upper bound by a factor $\sim2.4$. Our sensitivity to $10^{-19}$ eV shifts in molecular ions provides constraints on broad classes of new physics above $10^{13}$ eV, well beyond the direct reach of the LHC or any other near- or medium-term particle collider.

The study of transcriptional regulation controlling anterior-posterior tissue fates in Drosophila
Creators: name: Stevens, Cody Aldous
Publisher: name: No Publisher Supplied
Year: 2022

description: The establishment of boundaries during tissue patterning is a fundamental requirement during organs’ morphogenesis. Tissue patterning is governed by a relatively small number of cells signaling pathways. These pathways ultimately give rise to transcription factors (TFs), elements that control the spatiotemporal induction, or repression, of genes. Given their complexity and fundamental necessity in correct tissue morphogenesis, understanding how TFs are regulated is a monumental task. Here, we elucidate the spatiotemporal coordination of TFs that regulate the anterior posterior axis of the model organism Drosophila melanogaster. We focus on three signaling pathways involved in the anterior-posterior axis, the epidermal growth factor receptor (EGFR), the bone morphogenetic protein (BMP) pathway, and the Janus-Kinase (JAK/STAT) signaling pathway. We show EGFR and JAK/STAT signaling results in a coordinated activation of the ETS-transcription factor pointed (PNT) which we found regulates the posterior fate determinant midline (MID). Remarkably, PNT was found to be sufficient in establishing a posterior fate through repression of the ligand for the BMP pathway, decapentaplegic (DPP). Traditionally, the posterior was understood to be patterned by MID and its paralog H15 (H15). Given their importance, how transcription of MID/H15 was controlled remained unknown. Here, we found MID to be regulated via two cis-regulatory modules (CRMs). Through CRISPR/Cas9 genome editing, we show a redundancy of the CRMs. Deleting one or the other CRM did not substantially change MID expression, while deletion of both resulted in 60% reduction of MID. In addition, we found that the deletion of the upstream enhancer of MID eliminated H15, though fascinatingly, this affect was only tied to expression in oogenesis. While here we show how MID and H15 are self-regulated through CRMs, the trans elements that control the CRM regulation remains unclear. Through a sequential analysis of CRM bashing through reporter constructs, we illustrate trans regulation of CRMs through known MID regulators PNT, the Iroquois transcription factor mirror (MIRR), and the BMP pathway through its activated receptor thickveins (TKV). Using genome engineering and computational tools, the research presented here aims to illustrate how axis and boundaries among domains are formed, and how CRMs are regulated and controlled by TFs.

description: Kernel machines have sustained continuous progress in the field of quantum chemistry. In particular, they have proven to be successful in the low-data regime of force field reconstruction. This is because many equivariances and invariances due to physical symmetries can be incorporated into the kernel function to compensate for much larger datasets. So far, the scalability of kernel machines has however been hindered by its quadratic memory and cubical runtime complexity in the number of training points. While it is known, that iterative Krylov subspace solvers can overcome these burdens, their convergence crucially relies on effective preconditioners, which are elusive in practice. Effective preconditioners need to partially pre-solve the learning problem in a computationally cheap and numerically robust manner. Here, we consider the broad class of Nyström-type methods to construct preconditioners based on successively more sophisticated low-rank approximations of the original kernel matrix, each of which provides a different set of computational trade-offs. All considered methods aim to identify a representative subset of inducing (kernel) columns to approximate the dominant kernel spectrum.

Year: 2017

description: The intense investments and other unexpected events to the airline tested the knowledge and proficiency of the SCM's on time delivery of the requested parts/services whenever the aircraft grounds. Theobjective of this study was to assess the impact of SCM in Ethiopian Airlines Maintenance, Repair and Overhaul (MRO) service performance. The study employed both qualitative and quantitative approach (descriptive and inferential) to investigate the problem under study. The researcher used probability (simple random) and non-probability (judgmental) sampling techniques to select sampling population. The data collection considered all the team leaders and some selected senior technicians from component, engine & landing gear shops and base & line maintenance. It also took the team leaders and managers from SCM (Procurement, Logistics, Warehouse, AOG Desk, Material Planning, and Strategic sourcing) into consideration. The data collected were analyzed by using IBM SPSS for statistics. The findings clearly indicated the importance of SCM in Ethiopian MRO's survival, existence and its future expansion plan to serve customers from the whole world. Despite the limitations, the study created awareness about the concept, principle and practices of SCM in Ethiopian Airlines MRO performance. Thus, the close working relationship of the SCM as a whole with different departments including maintenance, repair shops & other supporting departments including finance & engineering is supposed to positively impact the competing power of the MRO and is currently resulting in better cost saving, efficient & timely use of resources and developing skills of employees towards aviation market level. Finally, the respondents agreed that the MRO should organize continuous trainings, experience sharing and workshop visits to its employees. And the respondents also believe that the MRO should improve communication, relationship and partnership with suppliers and operator

A hot gaseous galaxy halo candidate with Mg X absorption

description: The hot gas in galaxy halos may account for a significant fraction of missing baryons in galaxies, and some of these gases can be traced by high ionization absorption systems in QSO UV spectra. Using high S/N ratio $ HST$/COS spectra, we discovered a high ionization state system at $z=1.1912$ in the sightline toward \object{LBQS 1435-0134}, and two-components absorption lines are matched for Mg X, Ne VIII, Ne VI, O VI, Ne V, O V, Ne IV, O IV, N IV, O III, and H I. Mg X, detected for the first time ($5.8 σ$), is a particularly direct tracer of hot galactic halos, as its peak ion fraction occurs near $10^{6.1}\rm~ K$, about the temperature of a virialized hot galaxy halo of mass $\sim 0.5 M^*$. With Mg X and NeVIII, a photoionization model cannot reproduce the observed column densities with path lengths of galaxy halos. For collisional ionization models, one or two temperature models do not produce acceptable fits, but a three temperature model or a power law model can produce the observed results. In the power law model, ${\rm d}N/{\rm d}T = 10^{4.4\pm 2.2-[Z/X]} T^{1.55\pm 0.41}$ with temperatures in the range $10^{4.39\pm0.13} {\rm~K} < T < 10^{6.04\pm0.05}~ {\rm K}$, the total hydrogen column density is $8.2 \times 10^{19} (0.3Z_{\odot}/Z) \rm~ cm^{-2}$ and the positive power law index indicates most of the mass is at the high temperature end. We suggest that this absorption system is a hot volume-filled galaxy halo rather than interaction layers between the hot halo and cool clouds. The temperature dependence of the column density is likely due to the local mixture of multiple phase gases.

description: The recent discovery of intrinsic supercurrent diode effect, and its prompt observation in a rich variety of systems, has shown that nonreciprocal supercurrents naturally emerge when both space- and time-inversion symmetries are broken. In Josephson junctions, nonreciprocal supercurrent can be conveniently described in terms of spin-split Andreev states. Here, we demonstrate a sign reversal of the supercurrent diode effect, in both its AC and DC manifestations. In particular, the AC diode effect -- i.e., the asymmetry of the Josephson inductance as a function of the supercurrent -- allows us to probe the current-phase relation near equilibrium. Using a minimal theoretical model, we can then link the sign reversal of the AC diode effect to the so-called 0-$π$-like transition, a predicted, but still elusive feature of multi-channel junctions. Our results demonstrate the potential of inductance measurements as sensitive probes of the fundamental properties of unconventional Josephson junctions.

description: Titanium dioxide, TiO$_2$, has multiple applications in catalysis, energy conversion and memristive devices because of its electronic structure. Most of these applications utilize the naturally existing phases: rutile, anatase and brookite. Despite the simple form of TiO$_2$ and its wide uses, there is long-standing disagreement between theory and experiment on the energetic ordering of these phases that has never been resolved. We present the first analysis of phase stability at zero temperature using the highly accurate many-body fixed node diffusion Quantum Monte Carlo (QMC) method. We also include the effects of temperature by calculating the Helmholtz free energy including both internal energy and vibrational contributions from density functional perturbation theory based quasi harmonic phonon calculations. Our QMC calculations find that anatase is the most stable phase at zero temperature, consistent with many previous mean-field calculations. However, at elevated temperatures, rutile becomes the most stable phase. For all finite temperatures, brookite is always the least stable phase.

description: This paper investigates the effectiveness of monetary policy transmission mechanism on macroeconomic objectives in cases of selected East African Countries using a Dynamic Panel ARDL model with Pooled Mean Group estimation method. It specifically examines the dynamic responses of exchange rate, real interest rate, domestic credit and broad money supply on economic growth rate, consumer price index and balance of payment by employing annual data from 1992 to 2017. To do so, three models (economic growth rate, consumer price index and balance of payment) and different tests (i.e. descriptive analysis, panel unit root test, Pedroni co integration test and pooled mean group estimation) were used. The empirical evidence for economic growth rate model suggests that exchange rate, real interest rate and broad money supply have a positive and significant long-run impact for economic growth rate, while domestic credit has a negative and significant impact for economic growth rate in both short-run and long run. Exchange rate and broad money supply have no significant impact for economic growth in the short run but real interest rate has positive and significant impact in the short run. Similarly, empirical result for consumer price index model shows that exchange rate and real interest rate have a significant and negative long-run impact for consumer price index whereas domestic credit and broad money supply have a significant and positive long-run impact for consumer price index. The short-run analysis suggests that real interest rate, domestic credit and broad money supply have a negative short-run impact for consumer price index while exchange rate has a positive and insignificant short-run impact. For balance of payment model, exchange rate and domestic credit have positive insignificant short run and significant long-run impact for balance of payment. However, real interest rate and broad money supply have negative short run and long-run impact for the balance of payment with insignificant impact of real interest rate both in short run and long run. Therefore, real interest rate and broad money supply have no significant impact for balance of payment in selected east African countries. The monetary authorities and policy makers should know the relationship between monetary policy transmission mechanisms and macroeconomic objectives with their central bank monetary policy.

description: We study lattice QCD with $N_f=2$ Wilson fermions at nonzero imaginary chemical potential and nonzero temperature. We relate the Roberge - Weiss phase transition to the properties of dyons which are constituents of the KvBLL calorons. We present numerical evidence that the characteristic features of the spectral gap of the overlap Dirac operator as function of an angle modifying the boundary condition are determined by the $Z_3$ sector of the respective imaginary chemical potential. We then demonstrate that dyon excitations in thermal configurations could be responsible (in line with perturbative excitations) for these phenomena.

Bayesian analysis for a class of $α$-attractor inflationary models

description: We perform a Bayesian study of a generalization of the basic $α$-attractor T model given by the potential $V(ϕ)=V_0\left[1-\text{sech}^{p}\left(ϕ/\sqrt{6α}M_{pl}\right)\right]$ where $ϕ$ is the inflaton field and the parameter $α$ corresponds to the inverse curvature of the scalar manifold in the conformal or superconformal realizations of the attractor models. Such generalization is characterized by the power $p$ which includes the basic or base model for $p=2$. Once the priors for the parameters of the $α$-attractor potential are set by numerical exploration, we perform the corresponding statistical analysis for the cases $p=1\, , 2\, , 3\, ,4$, and derive posteriors. Considering the original $α$-attractor potential as the base model, we calculate the evidence for our generalization, and conclude that the $p=4$ model is preferred by the CMB data. We also present constraints for the parameter $α$. Interestingly, all the cases studied prefer a specific value for the tensor-to-scalar ratio given by $r\simeq 0.0025$.

description: Recent results link relativistic runaway electron avalanches (RREA) accelerated by the electric field in thunderclouds to high-energy atmospheric phenomena such as the Terrestrial Gamma-Ray Flashes (TGF). Research shows that the mere existence of runaway electron avalanches is not sufficient to generate TGF. In an attempt to settle this issue, a model of a relativistic feedback mechanism was suggested. In this paper, an analytical kinetic revision of the relativistic feedback mechanism is provided. It was shown that positron and gamma feedback mechanisms arise naturally from dynamics equations of RREA initiated independently by positrons and gamma-quanta. Establishing both mechanisms turned out to be enough to evaluate complete relativistic feedback. The electron avalanche multiplication factor is obtained, followed by a study of the minimal conditions of self-sustainable relativistic feedback in homogeneous electric fields and a discussion of the role of this mechanism in TGF and lightning initiation problems.

description: National COVID Cohort Collaborative (N3C) en- clave provides health researchers with a rich dataset from 76 contributing clinical sites. However, the harmonized data lacks certain details available in sites’ local electronic health records (EHRs), such as the principal diagnosis code for reported emergency department (ED) and inpatient (IP) visits. This means a principal diagnosis of COVID-19 can only be inferred by applying a time relationship between the visit dates and the record of infection and diagnosis. The purpose of this study is to perform a single-site sensitivity analysis modeled after an N3C study examining potential race-ethnicity based bias in hospitalization decisions during COVID-19 related ED visits. The analytic pipeline was first run in N3C, then reproduced locally with N3C data fields from a single-site, and finally run a third time using the additional principal diagnosis data. We find the effects of patient comorbidities and race-ethnicity groups on direct IP admittance to be consistent among the three cohorts with varying levels of statistical significance due to different sample sizes.

description: The outer heliosphere is a dynamic region shaped largely by the interaction between the solar wind and the interstellar medium. While interplanetary magnetic field and plasma observations by the Voyager spacecraft have significantly improved our understanding of this vast region, modeling the outer heliosphere still remains a challenge. We simulate the three-dimensional, time-dependent solar wind flow from 1 to 80 astronomical units (AU), where the solar wind is assumed to be supersonic, using a two-fluid model in which protons and interstellar neutral hydrogen atoms are treated as separate fluids. We use 1-day averages of the solar wind parameters from the OMNI data set as inner boundary conditions to reproduce time-dependent effects in a simplified manner which involves interpolation in both space and time. Our model generally agrees with Ulysses data in the inner heliosphere and Voyager data in the outer heliosphere. Ultimately, we present the model solar wind parameters extracted along the trajectory of New Horizons spacecraft. We compare our results with in situ plasma data taken between 11 and 33 AU and at the closest approach to Pluto on July 14, 2015.
