description: Spin qubits are contenders for scalable quantum computation because of their long coherence times demonstrated in a variety of materials, but individual control by frequency-selective addressing using pulsed spin resonance creates severe technical challenges for scaling up to many qubits. This individual resonance control strategy requires each spin to have a distinguishable frequency, imposing a maximum number of spins that can be individually driven before qubit crosstalk becomes unavoidable. Here we describe a complete strategy for controlling a large array of spins in quantum dots dressed by an on-resonance global field, namely a field that is constantly driving the spin qubits, to dynamically decouple from the effects of background magnetic field fluctuations. This approach -- previously implemented for the control of single electron spins bound to electrons in impurities -- is here harmonized with all other operations necessary for universal quantum computing with spins in quantum dots. We define the logical states as the dressed qubit states and discuss initialization and readout utilizing Pauli spin blockade, as well as single- and two-qubit control in the new basis. Finally, we critically analyze the limitations imposed by qubit variability and potential strategies to improve performance.

For timelike surfaces both Willmore and isothermic, we obtain a description by minimal surfaces similar to the classical results of Thomsen.

description: The ESA's Mars Express solar corona experiments were performed at two solar conjunctions in the years 2015 and 2017 by a number of radio telescopes in the European VLBI Network. This paper presents the methods to measure the frequency and phase fluctuations of the spacecraft radio signal, and the applications to study the characteristics of the plasma turbulence effects on the signal at a single station and at multiple stations via cross-correlation. The power spectra of the frequency fluctuations observed between 4.9 and 76.3 $\rm R_{s}$ have a power-law shape close to a Kolmogorov spectrum over the frequency interval $ ν_{lo}< ν700$ $\rm{km~s^{-1}}$ are derived from the cross-correlation of frequency fluctuations at $ν< 0.01$ Hz. The fast flow speeds of solar wind correspond to the high heliolatitude of the coronal region that the radio rays passed. The VLBI observations and analysis methods can be used to study the electron column density fluctuations and the turbulence at multiple spatial points in the inner solar wind by providing multiple lines of sight between the Earth and the spacecraft.
Area photometry with a multi-diode array
Creators: name: Mochnacki, Stefan Wladyslaw
Publisher: name: University of British Columbia
Year: 2010

description: An area photometer using a RETICON RA50x50 multi-diode array as the detector has been developed and used to observe the central regions of stellar systems. Computer programmes have been written to handle the recording of data and the subseguent analysis of images. A seguential image processing language called FIRM was developed for use with an IBM 370 under MTS. A theoretical analysis of the response of diode arrays to Gaussian star images shows that the light from a star can be integrated if the seeing diameter is greater than 2.0 times the diode centre to centre spacing. Aliasing at all freguencies is insignificant for any seeing diameter greater than about 2.5 diode spacings. Technigues for avoiding aliasing are discussed. Images of an area approximately 40" x 40" in the centre of the Sb galaxy NGC 4736(=M94) have been obtained through blue, visual and red filters. Subtraction of a simple, circularly symmetric model with King core radius 6".0 ± 0".5 reveals a small, bar-like central structure about 20" across. This central structure is aligned perpendicularly to the major axis of the galaxy and melds into previously photographed spiral structure. A bright point-like nucleus is also seen, but it does not stand out in the colour maps. ft sharp colour gradient exists at 10" radius. The reddest areas of the central region coincide roughly with patches of negative resi duals after model subtraction. A simple dynamical model is constructed for the inner region of NGC 4736, and it is proposed that two spiral systems exist in this galaxy, one inside the other with the inner system rotating more rapidly if it is a two-armed spiral. This model may also apply to other galaxies. A central mass to blue luminosity ratio of 2.4 to 3.6 is obtained for a range of model parameters. Observations of the X-ray emitting globular cluster NGC 7078 (=1115) reveal a number of red giants within 15" of the centre. A map of b-^-r instrumental colour shows that the nuclear cusp appears to be only a little redder than the main unresolved "background" population of the cluster, but the poor seeing does not allow resolution of the cusp within 2" of the cluster centre. The colour map confirms published spectroscopic results. There is very little radial colour variation when centred circular apertures are simulated.
The Agricultural Outlook for 1924

description: Excerpts from the report: The following statement of the agricultural outlook for 1924 based upon current information and upon reports from 43,000 farmers, representing every agricultural county in the country, stating their intentions regarding the planting of spring crops, has been prepared by the Bureau of Agricultural Economics of the United States Department of Agriculture to provide a basis upon which producers may make readjustments to meet economic changes. The general agricultural outlook for 1924 indicates that farmers are undertaking a normal production program. It is apparent, however, that agricultural production this year will still be attended by the difficulties arising from high wages and other costs, loss of farm workers, and the general disparity between prices of farm and urban products. Domestic demand for agricultural products is at a high level. Urban prosperity is reflected in a heavy current consumption of fibers and high quality foods, and this may be expected to continue into the summer. Foreign markets, on the whole, seem likely to maintain about the present level of demand for our cotton, pork, wheat, and tobacco. The situation this season with respect to labor, machinery, fertilizer, credit, and other cost items is not such as to favor any expansion in production.
What drives bitcoin? An approach from continuous local transfer entropy and deep learning classification models

description: Bitcoin has attracted attention from different market participants due to unpredictable price patterns. Sometimes, the price has exhibited big jumps. Bitcoin prices have also had extreme, unexpected crashes. We test the predictive power of a wide range of determinants on bitcoins' price direction under the continuous transfer entropy approach as a feature selection criterion. Accordingly, the statistically significant assets in the sense of permutation test on the nearest neighbour estimation of local transfer entropy are used as features or explanatory variables in a deep learning classification model to predict the price direction of bitcoin. The proposed variable selection methodology excludes the NASDAQ index and Tesla as drivers. Under different scenarios and metrics, the best results are obtained using the significant drivers during the pandemic as validation. In the test, the accuracy increased in the post-pandemic scenario of July 2020 to January 2021 without drivers. In other words, our results indicate that in times of high volatility, Bitcoin seems to autoregulate and does not need additional drivers to improve the accuracy of the price direction.

description: Parametric down-conversion (PDC) offers the possibility to control the fabrication of non-Gaussian states such as Fock states. However, in conventional PDC sources energy and momentum conservation introduce strict frequency and photon number correlations, which impact the fidelity of the prepared state. In our work we optimize the preparation of single-photon Fock states from the emission of waveguided PDC via spectral filtering. We study the effect of correlations via photon number resolving detection and quantum interference. Our measurements show how the reduction of mixedness due to filtering can be evaluated. Interfering the prepared photon with a coherent state we establish an experimentally measured fidelity of the produced target state of 78%.

description: Quality of Work Life (QWL) is a crucial factor influencing employee satisfaction, productivity, and retention. This study examines the quality of work life among employees at Raha Oil Mill, focusing on key aspects such as job security, work environment, compensation, work-life balance, and career growth opportunities. Using a combination of qualitative and quantitative methods, including surveys and interviews, the research analyzes how QWL affects employee engagement and overall organizational performance. The findings suggest that a positive work environment enhances employee commitment, whereas poor QWL leads to dissatisfaction and higher turnover. The study concludes with recommendations to improve QWL for better employee satisfaction and efficiency.

description: Understanding the kinetic selectivity of carbon nanotube growth at the scale of individual nanotubes is essential for the development of high chiral selectivity growth methods. Here we demonstrate that homodyne polarization microscopy can be used for high-throughput imaging of long individual carbon nanotubes under real growth conditions (at ambient pressure, on a substrate), and with sub-second time resolution. Our in situ observations on hundreds of individual nanotubes reveal that about half of them grow at a constant rate all along their lifetime while the other half exhibits stochastic changes in growth rates, and switches between growth, pause and shrinkage. Statistical analysis shows that the growth rate of a given nanotube essentially varies between two values, with similar average ratio (~1.7) regardless of whether the rate change is accompanied by a change in chirality. These switches indicate that the nanotube edge or the catalyst nanoparticle fluctuates between different configurations during growth.
Development Aid to Water Management in Mali: The Actors, ‘Global’ Paradigms, and ‘Local’ Translations
Creators: name: Cherlet, Jan Louisa Herman <1981>

Year: 2012
Subjects: SPS/08 Sociologia dei processi culturali e comunicativi

description: Development aid involves a complex network of numerous and extremely heterogeneous actors. Nevertheless, all actors seem to speak the same ‘development jargon’ and to display a congruence that extends from the donor over the professional consultant to the village chief. And although the ideas about what counts as ‘good’ and ‘bad’ aid have constantly changed over time —with new paradigms and policies sprouting every few years— the apparent congruence between actors more or less remains unchanged. How can this be explained? Is it a strategy of all actors to get into the pocket of the donor, or are the social dynamics in development aid more complex? When a new development paradigm appears, where does it come from and how does it gain support? Is this support really homogeneous?
To answer the questions, a multi-sited ethnography was conducted in the sector of water-related development aid, with a focus on 3 paradigms that are currently hegemonic in this sector: Integrated Water Resources Management, Capacity Building, and Adaptation to Climate Change. The sites of inquiry were: the headquarters of a multilateral organization, the headquarters of a development NGO, and the Inner Niger Delta in Mali.

The research shows that paradigm shifts do not happen overnight but that new paradigms have long lines of descent. Moreover, they require a lot of work from actors in order to become hegemonic; the actors need to create a tight network of support. Each actor, however, interprets the paradigms in a slightly different way, depending on the position in the network. They implant their own interests in their interpretation of the paradigm (the actors ‘translate’ their interests), regardless of whether they constitute the donor, a mediator, or the aid recipient. These translations are necessary to cement and reproduce the network.
Linear Relations Among Poincare Series via Harmonic Weak Maass Forms

description: We discuss the problem of the vanishing of Poincaré series. This problem is known to be related to the existence of weakly holomorphic forms with prescribed principal part. The obstruction to the existence is related to the pseudomodularity of Ramanujan's mock theta functions. We embed the space of weakly holomorphic modular forms into the larger space of harmonic weak Maass forms. From this perspective we discuss the linear relations between Poincaré series and the connection to Ramanujan's mock theta functions.
A Skyrme-type proposal for baryonic matter

description: The Skyrme model is a low-energy effective field theory for QCD, where the baryons emerge as soliton solutions. It is, however, not so easy within the standard Skyrme model to reproduce the almost exact linear growth of the nuclear masses with the baryon number (topological charge), due to the lack of Bogomolny solutions in this model, which has also hindered analytical progress. Here we identify a submodel within the Skyrme-type low energy effective action which does have a Bogomolny bound and exact Bogomolny solutions, and therefore, at least at the classical level, reproduces the nuclear masses by construction. Due to its high symmetry, this model qualitatively reproduces the main features of the liquid droplet model of nuclei. Finally, we discuss under which circumstances the proposed sextic term, which is of an essentially geometric and topological nature, can be expected to give a reasonable description of properties of nuclei.

description: Abstract

The transition from linear to circular economy requires the development of frameworks supporting the implementation of circular economy principles. This study's aim is to propose an approach to incorporate circular economy into the process of project environmental impact assessment through the inclusion of a life cycle thinking perspective. At the operational level, these objectives concern the implementation of life cycle thinking principles in waste and resources reuse evaluation, by adapting the steps already comprehended in the Environmental Impact Assessment procedure. A practical example shows the application of the proposed approach to a qualitative case study, specialized in the used natural cork stopper industry. This sector has an ambitious environmental sustainability objective: the preventive management of cork stopper waste is intended to create a virtuous context of increased cork stopper recycling, so as to avoid the disposal of this product in obsolete landfills. The identified criticalities show that life cycle thinking is a valuable paradigm to guide evaluation activities on waste management systems, in order to facilitate the movement of the analyzed waste up the waste hierarchy.

description: In the last few years, the concept of data lake has become trendy for data storage and analysis. Thus, several design alternatives have been proposed to build data lake systems. However, these proposals are difficult to evaluate as there are no commonly shared criteria for comparing data lake systems. Thus, we introduce DLBench, a benchmark to evaluate and compare data lake implementations that support textual and/or tabular contents. More concretely, we propose a data model made of both textual and raw tabular documents, a workload model composed of a set of various tasks, as well as a set of performance-based metrics, all relevant to the context of data lakes. As a proof of concept, we use DLBench to evaluate an open source data lake system we previously developed.

description: The Zero Degree Calorimeter (ZDC) of the ATLAS experiment at CERN is placed in the TAN of the LHC collider, covering the pseudorapidity region higher than 8.3. It is composed by 2 calorimeters, each one longitudinally segmented in 4 modules, located at 140 m from the IP exactly on the beam axis. The ZDC can detect neutral particles during pp collisions and it is a tool for diffractive physics. Here we present results on the forward photon energy distribution obtained using p-p collision data at sqrt{s} = 7 TeV. First the pi0 reconstruction will be used for the detector calibration with photons, then we will show results on the forward photon energy distribution in p-p collisions and the same distribution, but obtained using MC generators. Finally a comparison between data and MC will be shown.

description: Missing values occur commonly in the multidimensional data warehouses. They may generate problems of usefulness of data since the analysis performed on a multidimensional data warehouse is through different dimensions with hierarchies where we can roll up or drill down to the different parameters of analysis. Therefore, it's essential to complete these missing values in order to carry out a better analysis. There are existing data imputation methods which are suitable for numeric data, so they can be applied for fact tables but not for dimension tables. Some other data imputation methods need extra time and effort costs. As consequence, we propose in this article an internal data imputation method for multidimensional data warehouse based on the existing data and considering the intra-dimension and inter-dimension relationships.
A solid state detector head for astronomical applications
Creators: name: Lester, Timothy Paul
Publisher: name: University of British Columbia
Year: 2010

description: A detector head for housing self scanned silicon photo-detector arrays has been constructed for use in astronomy. It employs a unique frozen methanol cooling-"system and, although built specifically for the linear Reticon devices, it is capable of housing other linear or two dimensional monolithic arrays. This detector head is used with a control and data acquisition system that was developed at the University of British Columbia by the Institute of Astronomy and Space Science. A previous detector head, used with the above control system had incorporated a dry ice cooled 256A/17 Reticon array in a housing constructed, specifically for use on an F/1 concentric mirror spectrograph camera. This older device had many problems associated with it which made it difficult to operate and unreliable. With the 256A/17 Reticon mounted in the new camera head these problems have been eliminated. In particular, frosting no longer occurs, dark current has been reduced to a negligible level, and the readout noise has been reduced by a factor of two. As a result of this success, a 1024C/17 Reticon has been substituted for the 256 element array and there are plans for mounting a 100 x100 two dimensional array in this detector head.

description: We present the first near all-sky yield of oscillating red giants from the prime mission data of NASA's Transiting Exoplanet Survey Satellite (TESS). We apply machine learning towards long-cadence TESS photometry from the first data release by the MIT Quick-Look Pipeline to automatically detect the presence of red giant oscillations in frequency power spectra. The detected targets are conservatively vetted to produce a total of 158,505 oscillating red giants, which is an order of magnitude increase over the yield from Kepler and K2 and a lower limit to the possible yield of oscillating giants across TESS's nominal mission. For each detected target, we report effective temperatures and radii derived from colors and Gaia parallaxes, as well as estimates of their frequency at maximum oscillation power. Using our measurements, we present the first near all-sky Gaia-asteroseismology mass map, which shows global structures consistent with the expected stellar populations of our Galaxy. To demonstrate the strong potential of TESS asteroseismology for Galactic archeology even with only one month of observations, we identify 354 new candidates for oscillating giants in the Galactic halo, display the vertical mass gradient of the Milky Way disk, and visualize correlations of stellar masses with kinematic phase space substructures, velocity dispersions, and $α$-abundances.

Essays On CEO Compensation: New Evidence On The Managerial-Power
Vs. Optimal Contracting Debate
Creators: name: Bianchi, Giuliano <1981>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2013
Subjects: SECS-P/06 Economia applicata

description: This dissertation analyzes the effect of market analysts’ expectations of share prices (price targets) on executive compensation. It examines how well the estimated effects of price targets on compensation fit with two competing views on determining executive compensation: the arm’s length bargaining model, which assumes that a board seeks to maximize shareholders’ interests, and the managerial power model, which assumes that a board seeks to maximize managers’ compensation (Bebchuk et al. 2005). The first chapter documents the pattern of CEO pay from fiscal year 1996 to 2010. The second chapter analyzes the Institutional Broker Estimate System Detail History Price Target data file, which that reports analysts’ price targets for firms. I show that the number of price target announcements is positively associated with company share price’s volatility, that price targets are predictive of changes in the value of stocks, and that when analysts announce positive (negative) expectations of future stock price, share prices change in the same direction in the short run. The third chapter analyzes the effect of price targets on executive compensation. I find that analysts' price targets alter the composition of executive pay between cash-based compensation and stock-based compensation. When analysts forecast a rise (fall) in the share price for a firm, the compensation package tilts toward stock-based (cash-based) compensation. The substitution effect is stronger in companies that have weaker corporate governance. The fourth chapter explores the effect of the introduction of the Sarbanes-Oxley Act (SOX) in 2002 and its reinforcement in 2006 on the options granting process. I show that the introduction of SOX and its reinforcement eliminated the practice of backdating options but increased “spring-loading” of option grants around price targets announcements. Overall, the dissertation shows that price targets provide insights into the determinants of executive pay in favor of the managerial power model.
The Agricultural Outlook for 1925

description: Excerpts from the report: The general outlook for American agriculture is fairly encouraging this year as compared with recent years, although there may be a slackening in domestic demand for farm products next winter. Producers of the major farm products should follow a program of balanced and economical production about the same as last year. In general, the higher prices realized for 1924 products were due to reduced production, here or abroad, rather than to any marked improvement in demand. Farmers should continue to devote available resources to the reduction of existing indebtedness rather than to general expansion of production which might result in another period of low returns to farming. In making plans for 1925, farmers in each section should consider the outlook for all the commodities that they produce or can produce. Though in general, marked shifts in production do not seem advisable, yet each farmer may possibly add to his net income for the year by modifying the acreage of his crop or the numbers of his livestock in the light of the outlook for each of the products he can grow. From present indications ample credit for farming purposes will be available in most regions of the United States on more favorable terms. Interest rates are now somewhat lower than in recent years and needed credit should be arranged for early in the season. The present tendency in industry points to stronger competition for farm labor during the spring and summer of 1925 than prevailed during 1924. From present indications little change in farm equipment and upkeep costs are to be expected.
Laying the foundations: Building systems of support for OA books

description: This talk will outline the support systems that we see as vital for a flourishing OA books ecology as well as examining the challenges that are involved in both building and fostering engagement with such systems. In doing so, we will draw throughout on our experiences as part of the COPIM (Community-led Publication Infrastructures for Monographs) project, a partnership of researchers, librarians, publishers, and infrastructure providers that is in the process of building open and community-led infrastructures to support the funding, creation, dissemination, and preservation of long-form academic content. Books are only recently becoming prominent in conversations (and policies) about Open Access. The relative immaturity of the OA books landscape creates both opportunities and challenges: opportunities, in that much remains unsettled and there is the potential for motivated groups to have significant influence on the future funding, creation, sharing, and preservation of OA books; and challenges in building the infrastructures and creating the support networks among researchers, publishers, and librarians that will be required to make a successful transition to OA. Our talk will address three major challenges that we and our colleagues are grappling with: how to foster researcher engagement with, and enthusiasm for, OA books, in an environment when change is often driven by policy mandates and authors see very mixed levels of publisher support for OA; how to make it easier for institutions to offer forms of support to OA books focused initiatives in the face of scepticism from some colleagues and increasing degrees financial constraint; and how to build infrastructures to strengthen and improve the funding and dissemination of OA books, in the face of an increasing diversity of OA initiatives looking for support and a landscape dominated by infrastructures designed to promote the circulation of non-OA content.

description: We present a computer algebra approach to proving identities on Bernoulli polynomials and Euler polynomials by using the extended Zeilberger's algorithm given by Chen, Hou and Mu. The key idea is to use the contour integral definitions of the Bernoulli and Euler numbers to establish recurrence relations on the integrands. Such recurrence relations have certain parameter free properties which lead to the required identities without computing the integrals.

description: We introduce a statistical method to detect nonlinearity and nonstationarity in time series, that works even for short sequences and in presence of noise. The method has a discrimination power similar to that of the most advanced estimators on the market, yet it depends only on one parameter, is easier to implement and faster. Applications to real data sets reject the null hypothesis of an underlying stationary linear stochastic process with a higher confidence interval than the best known nonlinear discriminators up to date.

ANIMA D2.5 - Critical review of Balanced Approach Implementation across EU Member States

Case Studies

description: This report presents an assessment of Balanced-Approach implementation by airports across European Member States. The main aim is to identify the range of operational improvements, land-use planning interventions and operational restrictions introduced by airports to address specific noise management challenges.

The research was conducted via in-depth case studies across 12 airports and one community organisation, using publicly available documentation and stakeholder interviews at each organisation. The result is 13 thorough case studies on the adoption of Balanced Approach at each airport, and specifically the implementation of a noise abatement intervention relating to the three Balanced Approach pillars of Land-Use Planning, Operational Procedures, and Operating Restrictions.

The case studies address the processes through which interventions are implemented, namely:

	Identification of the need for change.
	Design of intervention options.
	Selection of implemented intervention.
	Implementation of the intervention.
	Post-Implementation Evaluation.

By focusing on these processes, it has be possible to identify Best Practice elements that lead to successful implementation of an intervention, which may be transposable to other airports, and thus inform on the Best Practice Portal being developed in ANIMA Task 5.5. Moreover, this approach allows for tools, metrics, monitoring and modelling, and communication strategies used in each case to be identified and to inform on ANIMA Sub-Tasks 2.3.2 and 2.3.3.

The work has found that communication and engagement play a large and significant role in the implementation of noise abatement interventions across different Balanced Approach interventions, and throughout the entire process of implementation. Communication and engagement should therefore be made a more integral component of the Balanced Approach.

Land-Use Planning was found to be of particular importance to rapidly growing airports, for which pro-active engagement in the Balanced Approach can lead to avoidance of operating restrictions as the airport grows. Integration of different Balanced Approach elements in the same instance was found to be lacking in the case studies – with interventions typically being implemented as one-off actions independent. Considering interdependencies was found to be relatively lacking in intervention – noise being the primary driver behind the majority of case studies. A range of modelling and monitoring protocols were identified, disseminated through a range of metrics.

description: Magneto-optical sensors including spin noise spectroscopies and magneto-optical Kerr effect microscopies are now ubiquitous tools for materials characterization that can provide new understanding of spin dynamics, hyperfine interactions, spin-orbit interactions, and charge-carrier g-factors. Both interferometric and intensity-difference measurements can provide photon shot-noise limited sensitivity, but further improvements in sensitivity with classical resources require either increased laser power that can induce unwanted heating and electronic perturbations or increased measurement times that can obscure out-of-equilibrium dynamics and radically slow experimental throughput. Proof-of-principle measurements have already demonstrated quantum enhanced spin noise measurements with a squeezed readout field that are likely to be critical to the non-perturbative characterization of spin excitations in quantum materials that emerge at low temperatures. Here, we propose a truncated nonlinear interferometric readout for low-temperature magneto-optical Kerr effect measurements that is accessible with today's quantum optical resources. We show that 10 $\text{nrad}/\sqrt{\text{Hz}}$ sensitivity is achievable with optical power as small as 1 $μ$W such that a realistic $T$ = 83 mK can be maintained in commercially available dilution refrigerators. The quantum advantage for the proposed measurements persists even in the limit of large loss and small squeezing parameters.
