Subjects: irrigation development, investments, poverty, food security, agricultural productivity

description: Irrigation plays a vital role in increasing agricultural productivity. Several studies suggest that crop yields are consistently greater in irrigated areas than in rain-fed areas. Scholars have mostly studied one aspect of irrigation's effects on agricultural productivity, poverty, or food security. This study examines all three aspects simultaneously to fill the gap left by these scholars. Using quantitative methodology, previous research has established a relationship between irrigation investments and productivity in eighteen developing nations. Studies have found a positive link between investment and agricultural productivity using a non-parametric technique. This study used a mixed methods approach to gain an in-depth understanding of the phenomenon. The study observed that irrigation impacted livelihoods in a number of ways including employment creation, food and nutrition security. Group irrigation need to be organised into cooperative organizations so that they can have better access to inputs, financing, and markets.

Subjects: intangible assets, intellectual capital, smes, structured literature review, performance

description: In today’s knowledge-based society, intangibles are providing crucial resources for the firm’s survival and growth. In particular, intellectual capital (IC) should be properly managed to increase economic value. However, the conceptualization of this construct is mainly grounded on the features of large firms even if the relevance of SMEs in the economy at international level is growing. To answer to the call for more IC research in SMEs, this study adopts a structured literature review to understand how the concept of IC is conceived in SMEs, by analysing IC components that mainly impact SMEs’ performance. Results show that a core and diversified set of IC dimensions is supporting different areas of performance. IC in SMEs is conceived of as a wider concept compared to existing frameworks. Results show that intangibles play a fundamental role in SMEs, and, therefore, their proper measurement and management becomes of vital importance for SMEs. Results from this study enrich the literature on the conceptualization of IC by focusing on a specific typology of firm, which deserves specific research effort, it extends the knowledge of IC in practice, by focusing on the items of IC with a relevant role in affecting SMEs performance and it provides support to the role of IC management in SMEs.

description: We present structural parameters for 51 compact star clusters from the survey of star clusters conducted in the South-West field of the M31 disk by Kodaira et al. (2004). Structural parameters of the clusters were derived by fitting the 2-D King and EFF (Elson, Fall and Freeman 1987) models to the V-band cluster images. Structural parameters derived for two M31 clusters, which are in common with the study based on the HST data (Barmby et al. 2002), are consistent with earlier determination. The M31 star cluster structural parameters in general are compatible with the corresponding Milky Way galaxy and Magellanic Clouds cluster parameters.

Year: 2006
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: The time-convolutionless master equation for the electronic populations is derived for a generic electron-phonon Hamiltonian. The equation can be used in the regimes where the golden rule approach is not applicable. The equation is applied to study the electronic relaxation in several models with the finite number normal modes. For such mesoscopic systems the relaxation behavior differs substantially from the simple exponential relaxation. In particular, the equation shows the appearance of the recurrence phenomena on a time-scale determined by the slowest mode of the system. The formal results are quite general and can be used for a wide range of physical systems. Numerical results are presented for a two level system coupled to Ohmic and super-Ohmic baths, as well as for a model of charge-transfer dynamics between semiconducting organic polymers.

description: The long-time behavior of transport coefficients in a model for spatially heterogeneous media in two and three dimensions is investigated by Molecular Dynamics simulations. The behavior of the velocity auto-correlation function is rationalized in terms of a competition of the critical relaxation due to the underlying percolation transition and the hydrodynamic power-law anomalies. In two dimensions and in the absence of a diffusive mode, another power law anomaly due to trapping is found with an exponent -3 instead of -2. Further, the logarithmic divergence of the Burnett coefficient is corroborated in the dilute limit; at finite density, however, it is dominated by stronger divergences.

description: The gate bias dependency of conductivity is examined in two Si quantum wells with well thickness tw = 7 nm and tw = 14 nm. The conductivity of the thinner device behaves smoothly whereas the thicker device shows strong non-monotonic features as a function of gate voltages. We show that a strong minimum in conductivity occurs close to the threshold of second sub-band. Another minimum is seen at high electron density at symmetric well potential. This feature is addressed to sub-band wave function delocalization in the quantization direction.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present the formalism for a new generation of unquenched quark models in which quark-antiquark pair effects are taken into account in an explicit form via a microscopic QCD-inspired quark-antiquark creation mechanism. No truncation in the sum over all the big tower of states is necessary since these states are automatically generated by means of powerful group-theoretical techniques. An important check on the formalism and the numerical results is provided by the closure limit. As an application, the effect of quark-antiquark pairs on the strange content of the proton spin, $Δs$, is discussed. The contributions of the up and down quarks, $Δu$ and $Δd$, are also calculated. This has become possible after solving the difficult problem of permutational symmetry related to quark rearrangements. Finally, we present some preliminary results in the closure limit as well as an outlook for future applications.

description: We study the morphology of convergence maps by perturbatively reconstructing their Minkowski Functionals (MFs). We present a systematics study using a set of three generalised skew-spectra as a function of source redshift and smoothing angular scale. Using an approach based on pseudo-$S_{\ell}$s (PSL) we show how these spectra will allow reconstruction of MFs in the presence of an arbitrary mask and inhomogeneous noise in an unbiased way. Our theoretical predictions are based on a recently introduced fitting function to the bispectrum. We compare our results against state-of-the art numerical simulations and find an excellent agreement. The reconstruction can be carried out in a controlled manner as a function of angular harmonics $\ell$ and source redshift $z_s$ which allows for a greater handle on any possible sources of non-Gaussianity. Our method has the advantage of estimating the topology of convergence maps directly using shear data. We also study weak lensing convergence maps inferred from Cosmic Microwave Background (CMB) observations; and we find that, though less significant at low redshift, the post-Born corrections play an important role in any modelling of the non-Gaussianity of convergence maps at higher redshift. We also study the cross-correlations of estimates from different tomographic bins.

NFT in art business: real opportunity or short-term novelty? A theoretical approach

description: In recent years the blockchain and the digital innovation has caused paradigm shifts across very disparate sectors of our society (Rangone and Busolli, 2021). In such a context, the non-fungible tokens (NFT) more specifically have started to transform everything from finance to art (Kashevarova and Starikova, 2022; Qin et al., 2021). There’s good reason to suspect that, once their full potential is realized, almost no industry will be left untouched. Although the technology has been around for a while, NFTs took off in 2020 and have been growing in popularity ever since, particularly in the digital art world (Habrel, 2022; Dragos Popescu, 2021; Trautman, 2021). In that year, the rapid growth of the NFT sector and its numerous mentions in mainstream media surprised many in the crypto space. In 2021, many NFTs from the most popular NFT collections, such as crypto kittens, crypto punks, and Decentraland land plots, were sold for insanely high prices. According to DappRadar (2021), a service that records the buying and selling of NFTs, the trading volume of NFTs reached a record high of $22 billion in 2021. This success can be attributed to mainstream businesses entering the NFT industry. As today’s hottest digital assets, non-fungible tokens have taken the arts and investment worlds by storm. Some claim that NFTs are the future of artwork and that the next Vincent van Gogh will be a computer programmer. Many see NFTs as viable, profitable investments tailored for younger, digitally savvy buyers. Detractors wonder if NFTs are a short-term novelty. Through a theoretical approach, this paper investigates the scenarios and the possible criticalities of the NFTs’ spread in the specific sector of art business.

description: It has been suggested that the Crab pulsar's proper motion is well aligned with the symmetry axis of the pulsar wind nebula. We have re-visited this question, examining over 6 years of F547M WFPC2 chip 3 images to obtain a best-fit value of $μ_\ast = 14.9 \pm 0.8$mas/yr at PA $278\arcdeg \pm 3\arcdeg$. At $26\arcdeg\pm 3\arcdeg$ to the nebula axis, this substantially relaxes constraints on the birth kick of this pulsar. Such misalignment allows the momentum to be imparted over $\sim$1s timescales.

description: The lack of guided exercises and practical opportunities to learn about cybersecurity in a practical way makes it difficult for security experts to improve their proficiency. Capture the Flag events and Cyber Ranges are ideal for cybersecurity training. Thereby, the participants usually compete in teams against each other, or have to defend themselves in a specific scenario. As organizers of yearly events, we present a taxonomy for interactive cyber training and education. The proposed taxonomy includes different factors of the technical setup, audience, training environment, and training setup. By the comprehensive taxonomy, different aspects of interactive training are considered. This can help trainings to improve and to be established successfully. The provided taxonomy is extendable and can be used in further application areas as research on new security technologies.

We provide a recipe for identifying the maximal infinite virtually cyclic subgroups of Coxeter groups which are lattices in $O^+(n,1)= \iso(\mathbb H^n)$. We use the information we obtain to explicitly compute the lower algebraic K-theory of the Coxeter group $\gt$ (a non-uniform lattice in $O^+(3,1)$). Part of this computation involves calculating certain Waldhausen Nil-groups for $\mathbb Z[D_2]$, $\mathbb Z[D_3]$.

description: We consider an open manifold which is the interior of a compact manifold with boundary. Assuming gauge invariance, we classify magnetic fields with compact support into being trapping or non-trapping. We study spectral properties of the associated magnetic Laplacian for a class of Riemannian metrics which includes complete hyperbolic metrics of finite volume. When $B$ is non-trapping, the magnetic Laplacian has nonempty essential spectrum. Using Mourre theory, we show the absence of singular continuous spectrum and the local finiteness of the point spectrum. When $B$ is trapping, the spectrum is discrete and obeys the Weyl law. The existence of trapping magnetic fields with compact support depends on cohomological conditions, indicating a new and very strong long-range effect. In the non-gauge invariant case, we exhibit a strong Aharonov-Bohm effect. On hyperbolic surfaces with at least two cusps, we show that the magnetic Laplacian associated to every magnetic field with compact support has purely discrete spectrum for some choices of the vector potential, while other choices lead to a situation of limit absorption principle. We also study perturbations of the metric. We show that in the Mourre theory it is not necessary to require a decay of the derivatives of the perturbation. This very singular perturbation is then brought closer to the perturbation of a potential.

description: Recent work about synthetic indoor datasets from perspective views has shown significant improvements of object detection results with Convolutional Neural Networks(CNNs). In this paper, we introduce THEODORE: a novel, large-scale indoor dataset containing 100,000 high-resolution diversified fisheye images with 14 classes. To this end, we create 3D virtual environments of living rooms, different human characters and interior textures. Beside capturing fisheye images from virtual environments we create annotations for semantic segmentation, instance masks and bounding boxes for object detection tasks. We compare our synthetic dataset to state of the art real-world datasets for omnidirectional images. Based on MS COCO weights, we show that our dataset is well suited for fine-tuning CNNs for object detection. Through a high generalization of our models by means of image synthesis and domain randomization, we reach an AP up to 0.84 for class person on High-Definition Analytics dataset.

Subjects: Barcelona Declaration on Open Research Information

description: At the University of Groningen, an important driver of the transition to open research information has been our academic community. Engaging faculty and researchers alongside librarians, policy-makers and research support professionals has proven to be essential for advancing broad organizational buy-in and enabling the shift required to fulfill our commitments to open research information. In this talk, I will discuss the challenges we have encountered in our effort to build broad-based engagement and share some of the key strategies we have employed to overcome them.

A significant part of our approach has been to leverage internal interdisciplinary structures such as the Open Science Program, Open Science Community Groningen, Young Academy Groningen, CoARA faculty and staff network, and our Rewards and Recognition committee, among others. Engaging these in the drive to promote the openness of research information has helped foster cross-disciplinary collaboration and nurture a sense of ownership among academic staff.

Awareness of the benefits of open research information and the issues driving the transition motivates researchers to support and advocate for it. Their involvement in dialogue and policy-making helps ensure that policies meet their needs and also empowers us to navigate institutional resistance more effectively. The talk will provide attendees with practical insights into enhancing research community engagement, and highlight how this can help enable them in their efforts to implement the Barcelona Declaration. The short session aims to inspire and provide actionable ideas for fostering engagement and commitment to advancing the adoption of open research information.

The ratios of the decay times are discussed in terms of the number of transition channels determined by the excitonic fine structure and a specific transition time for each channel. The measured ratio for the neutral complexes is 1.7 deviating from the theoretically predicted value of 2. A ratio of 1.5 for the positively charged exciton and biexciton decay time is predicted and exactly matched by the measured ratio indicating identical specific transition times for the transition channels involved.

Year: 2020

description: Canonical instanton theory is known to overestimate the rate constant close to a system-dependent crossover temperature and is inapplicable above that temperature. We compare the accuracy of the reaction rate constants calculated using recent semi-classical rate expressions to those from canonical instanton theory. We show that rate constants calculated purely from solving the stability matrix for the action in degrees of freedom orthogonal to the instanton path is not applicable at arbitrarily low temperatures and employ two methods to overcome this. Furthermore, as a by-product of the developed methods, we derive a simple correction to canonical instanton theory that can alleviate this known overestimation of rate constants close to the crossover temperature. The combined methods accurately reproduce the rate constants of the canonical theory along the whole temperature range without the spurious overestimation near the crossover temperature. We calculate and compare rate constants on three different reactions: H in the Müller--Brown potential, methylhydroxycarbene $\to$ acetaldehyde and H$_2$ + OH $\to$ H + H$_2$O.
Spectral Characterization of Solid-State Photocathode Emission

Subjects: Uncategorized

description: The goal of this thesis work is to connect the electronic properties of a crystal (i.e. its band structure) to its photoemission properties and thereby provide a roadmap for the discovery (or development) of photocathode materials with low intrinsic emittance. I have introduced a new photoemission formalism that includes the triangular barrier generated by an applied surface acceleration field Eacc of the electron gun, transverse momentum conservation, and the properties of the bulk band and vacuum states involved in the photoemission process. The direct connection between the electronic band structure of a solid-state photocathode material and it’s experimentally determined spectral photoemission properties (the mean transverse energy (MTE) and quantum efficiency (QE)) is shown for a Rh(110) photocathode at 300K. In accordance with theoretical expectations, a low effective mass (i.e. high dispersion) of the bulk emission bands is shown to be the cause of the significant reduction in the MTE of photoemission from single-crystal Hf(0001) photocathode. Further, modification of the one-step photoemission formalism allowed for an explanation of the observed spectral dependence of the MTE from a Hf(0001)/HfO2 photocathode through the inclusion of defect state emission from the native oxide layer. In addition, a record low MTE value of 6meV was observed for Cu(001) at 35K and an excess photoemission energy E of 0.11eV.

description: The observation that phenotypic variability is ubiquitous in isogenic populations has led to a multitude of experimental and theoretical studies seeking to probe the causes and consequences of this variability. Whether it be in the context of antibiotic treatments or exponential growth in constant environments, non-genetic variability has shown to have significant effects on population dynamics. Here, we review research that elucidates the relationship between cell-to-cell variability and population dynamics. After summarizing the relevant experimental observations, we discuss models of bet-hedging and phenotypic switching. In the context of these models, we discuss how switching between phenotypes at the single-cell level can help populations survive in uncertain environments. Next, we review more fine-grained models of phenotypic variability where the relationship between single-cell growth rates, generation times and cell sizes is explicitly considered. Variability in these traits can have significant effects on the population dynamics, even in a constant environment. We show how these effects can be highly sensitive to the underlying model assumptions. We close by discussing a number of open questions, such as how environmental and intrinsic variability interact and what the role of non-genetic variability in evolutionary dynamics is.

description: Silicon and germanium are perhaps the two most well-understood semiconductor materials in the context of solid state device technologies and more recently micromachining and nanotechnology. Meanwhile, these two materials are also important in the field of infrared lens design. Optical instruments designed for the wavelength range where these two materials are transmissive achieve best performance when cooled to cryogenic temperatures to enhance signal from the scene over instrument background radiation. In order to enable high quality lens designs using silicon and germanium at cryogenic temperatures, we have measured the absolute refractive index of multiple prisms of these two materials using the Cryogenic, High-Accuracy Refraction Measuring System (CHARMS) at NASA Goddard Space Flight Center, as a function of both wavelength and temperature. For silicon, we report absolute refractive index and thermo-optic coefficient (dn/dT) at temperatures ranging from 20 to 300 K at wavelengths from 1.1 to 5.6 microns, while for germanium, we cover temperatures ranging from 20 to 300 K and wavelengths from 1.9 to 5.5 microns. We compare our measurements with others in the literature and provide temperature-dependent Sellmeier coefficients based on our data to allow accurate interpolation of index to other wavelengths and temperatures. Citing the wide variety of values for the refractive indices of these two materials found in the literature, we reiterate the importance of measuring the refractive index of a sample from the same batch of raw material from which final optical components are cut when absolute accuracy greater than +/-5 x 10^-3 is desired.

The FWF's approach to Open Research Information
Creators: name: Rieck, Katharina
Publisher: name: Zenodo
Year: 2024
Subjects: Barcelona Declaration on Open Research Information

description: The Austrian Science Fund (FWF) is strongly committed to the principles of Open Science, advocating for over two decades to ensure that research outputs are as openly accessible as possible. This includes ensuring that data on research funding and grants is openly available and interoperable. Central to this effort is the use of persistent identifiers in grant metadata. All FWF projects are assigned a grant DOI, which must be cited as the identifier of the approved project in any research output. Since 2016, ORCID has been mandatory for all researchers submitting proposals to the FWF, and ROR IDs are used in project metadata to ensure unique identification of research institutions. This accessibility and interoperability of grant metadata supports the efficient sharing of information of research projects globally. Beyond persistent identifiers, the FWF has supported open research infrastructures for over a decade and openly shares information on funded initiatives on its website.

This talk will specifically address how the FWF’s efforts align with and support the commitments outlined in the Barcelona Declaration on Open Research Information. By sharing the FWF’s strategies and practices, the aim is to provide other signatories with practical insights and actionable steps to enhance the openness and interoperability of grant information. Other funders might find this particularly useful in implementing similar frameworks within their organizations. Additionally, the talk will highlight FWF’s current projects in the field of open research information and outline future plans.

description: CCD BVI photometry is presented for 7 previously unstudied star clusters projected toward the inner side of the Galaxy: Trumpler 23, Lynga 3, Collinder 307, Ruprecht 134, ESO552SC16, AL 5 and Kronberger 3. Color magnitude diagrams of the cluster regions allow us to conclude that Lynga 3 and ESO552SC16, are not clusters, but groups of bright stars probably located in the Carina-Sagittarius spiral arm. AL 5 and Kronberger 3 are so embedded in a dense stellar field that we cannot confirm their nature. Trumpler~ 3 and Ruprecht 134 are two intermediate-age open clusters located well inside the solar ring which deserve further attention. Finally, Collinder 307 is an obscured younger cluster (250 Myr) located in the Carina-Sagittarius spiral arm. Our results emphasize the difficulty to search for open clusters in the inner regions of the Galaxy due to the richness of the field and the patchy nature of the interstellar absorption, but at the same time significantly contribute to a better understanding of this complicated regions of the Milky Way.

Competition of Fermi surface symmetry breaking and superconductivity

description: We analyze a mean-field model of electrons on a square lattice with two types of interaction: forward scattering favoring a d-wave Pomeranchuk instability and a BCS pairing interaction driving d-wave superconductivity. Tuning the interaction parameters a rich variety of phase diagrams is obtained. If the BCS interaction is not too strong, Fermi surface symmetry breaking is stabilized around van Hove filling, and coexists with superconductivity at low temperatures. For pure forward scattering Fermi surface symmetry breaking occurs typically via a first order transition at low temperatures. The presence of superconductivity reduces the first order character of this transition and, if strong enough, can turn it into a continuous one. This gives rise to a quantum critical point within the superconducting phase. The superconducting gap tends to suppress Fermi surface symmetry breaking. For a relatively strong BCS interaction, Fermi surface symmetry breaking can be limited to intermediate temperatures, or can be suppressed completely by pairing.

description: Quantum materials having Dirac fermions in conjunction with superconductivity is believed to be the candidate materials to realize exotic physics as well as advanced technology. Angle resolved photoemission spectroscopy (ARPES), a direct probe of the electronic structure, has been extensively used to study these materials. However, experiments often exhibit conflicting results on dimensionality and momentum of the Dirac Fermions (e.g. Dirac states in BiPd, a novel non-centrosymmetric superconductor), which is crucial for the determination of the symmetry, time-reversal invariant momenta and other emerging properties. Employing high-resolution ARPES at varied conditions, we demonstrated a methodology to identify the location of the Dirac node accurately and discover that the deviation from two-dimensionality of the Dirac states in BiPd proposed earlier is not a material property. These results helped to reveal the topology of the anisotropy of the Dirac states accurately. We have constructed a model Hamiltonian considering higher-order spin-orbit terms and demonstrate that this model provides an excellent description of the observed anisotropy. Intriguing features of the Dirac states in a non-centrosymmetric superconductor revealed in this study expected to have significant implication in the properties of topological superconductors.

description: La Non financial Information (DNF) introdotta sia dal Parlamento Europeo nel 2014 che in altri Stati del mondo trova ampio dibattito negli studi aziendalistici e una crescente attenzioni associata agli elementi di ESG definiti dalla Corporate Social Responsability. La CONSOB (2022) in Italia vede nell’obbligo di redazione della DNF un elemento chiave per il cambiamento aziendale orientato alla sostenibilità. Per questo motivo lo studio utilizza un duplice approccio metodologico. L’analisi bibliometrica è volta a confermare e indagare i trend della letteratura sulla DNF partendo dalle evidenze prodotte da Turzo ed al., (2022) attraverso l’analisi dell’ultimo periodo. La content analysis analizza variabili, approcci e contenuti che evidenzino la direzione e i gap nei report non finanziari prodotti in Italia nel 2022. I risultati confermano la continuità di tre filoni di ricerca associati a sviluppo ed elementi della DNF, analisi delle performance associate agli ESG nella reportistica e effetti e ricaduta della DNF sulle aziende. Si confermano inoltre approcci teorici orientati all’uso della legitimacy theory, della trasparenza e dell’accountability. La content analysis conferma alcuni temi evidenziati nella letteratura emergente. Analisi bibliometrica e content analysis individuano nuovi filoni di ricerca emergenti e gap nell’attuale letteratura che richiedono la futura attenzione degli accademici.

description: Adherence will have an impact on therapy because schizophrenia is a chronic mental disorder that requires long-term treatment. One strategy to improve adherence to medications is motivational interviewing (MI), although more study is needed to see how well it works and whether it has any other effects on schizophrenia. The study aimed to assess the effectiveness of motivational interviews in improving adherence to medications and other positive impacts on PwS. A literature review using PubMed, Science Direct, Springerlink, and google scholar databases from 2010-2023 focused on keywords adherence, schizophrenia, and motivational interviewing. The results showed that MI has inconsistencies in their effect on improving medication adherence in PwS, but some studies found evidence of an association between MI and other outcomes, such as improvement in psychotic symptoms and decreased hospitalisation rates. Differences in patient characteristics and MI interventions in each study, the to perform MI techniques, and the trusting relationship built by the counsellor with the patient will affect the impact of MI on adherence. MI showed inconsistencies in improving medication adherence in people with schizophrenia. Several factors will affect the effectiveness of MI. However, MI also has the potential to improve psychosis symptoms and reduce hospitalisation rates, although more research is needed.
Looking at the world through a windshield: a historical geography of the trucking industry in British Columbia
Creators: name: Evans, Rhys
Publisher: name: University of British Columbia

description: The trucking industry has been an extremely important part of the process of economic growth and cultural integration in British Columbia. The specific trajectories taken by both the provincial economy and the trucking industry are entwined, each shaping the other. The story of trucking in British Columbia is a story of constant change. Forced to respond to changing political and economic conditions, the industry has taken at least three different configurations. The state of the roads, the trucks and the industry form the three main axes of inquiry. This thesis explores the history of the industry in specific detail in order to understand the constraints the provincial economy, culture and landscape has brought to the creation of a viable trucking industry. It al examines the ways the industry has, in turn, affected the economy and culture of British Columbia.
