title: Using Wavelets as a Computational and Theoretical Tool for Homogenization
Creators: name: Watkins, Laura Lee
Publisher: name: Utah State University
Year: 2005

description: Since the cost of petroleum fluctuates widely, it is advisable to optimize extraction of oil and other hydrocarbon products form existing oil reserves. Because of the costs involved in recovering oil from a reservoir, predicting reservoir performance can be a useful tool for determining whether continued extraction might be profitable. This can be done using computer simulations of the physical processes involved such as pressure/head, fluid velocities, and so forth. Fluid flow within a reservoir occurs at a very small scale relative to the size of the reservoir. This size difference makes performing simulations at the physically appropriate scale unfeasible. Homogenization is a technique used in reservoir simulation to upscale small scale dependent behavior, such as a permeability tensor, to make simulation feasible. To calculate a homogenized permeability tensor, the solution to a system of uncoupled elliptic partial differential equations must be found repeatedly throughout the reservoir. Generally, the solution to the system of differential equations is approximated numerically using finite element or finite difference methods. We explore using wavelets as a means of characterizing homogenization in reservoir simulations in the search for fast algorithms for computing equivalent tensors. In addition to the analogy developed between homogenization and wavelets, proofs of convergence results from homogenization within the wavelet characterization are considered.

description: The transverse-target single-spin asymmetry for inclusive deep-inelastic scattering with effectively unpolarized electron and positron beams off a transversely polarized hydrogen target was measured, with the goal of searching for a two-photon exchange signal in the kinematic range 0.007 < x_B < 0.9 and 0.25 GeV**2 < Q**2 < 20 GeV**2. In two separate regions Q**2 > 1 GeV**2 and Q**2 < 1 GeV**2, and for both electron and positron beams, the asymmetries are found to be consistent with zero within statistical and systematic uncertainties, which are of order 10**(-3) for the asymmetries integrated over x_B.

description: Many multi-planet systems have been discovered in recent years. Some of them are in mean-motion resonances (MMR). Planet formation theory was successful in explaining the formation of 2:1, 3:1 and other low resonances as a result of convergent migration. However, higher order resonances require high initial orbital eccentricities in order to be formed by this process and these are in general unexpected in a dissipative disk. We present a way of generating large initial eccentricities using additional planets. This procedure allows us to form high order MMRs and predict new planets using a genetic N-body code.

description: In line with the Open Research Data Pilot regulations of the Horizon 2020 programme (H2020) (Grant Agreement Number 101007990 - VITALISE, 2021), the purpose of this deliverable is to present the first version Data Management Plan (DMP) of the VITALISE project (Open Access - H2020 Online Manual, 2017). The document provides provisory information regarding the data to be collected during the project, as well as addresses the issue of data re-use for further exploitation by expanding on the manner in which the data will be made accessible and gives information on the data’s curation and preservation. According to the FAIR (Findable, Accessible, Interoperable and Reusable) Data Management guidelines in Horizon 2020 and in agreement with the General Data Protection Regulation (EU) 2016/679 (GDPR) (General Data Protection Regulation (EU GDPR) 2016/679 of the European Parliament and of the Council of 27 April 2016 on the Protection of Natural Persons with Regard to the Processing of Personal Data and on the Free Movement of Such Data and Repealing Directive 95/46/EC, 2016), all datasets to be produced and collected and shared amongst the partners during the project were identified and an first version of a list containing all relevant details was established. Currently the project is set to develop and share a collection of datasets related to patient rehabilitation supported by technology, transitional care and everyday living environments. These datasets will also be uploaded to the VITALISE platform that will facilitate open access data processing allowing for federated and harmonized living lab data access. Considering the fact that the VITALISE datasets will at their majority be produced and collected from human participants, the respective data (raw or processed) should be managed in total agreement to the guidelines and regulations in place regarding ethical and privacy issues related to datasets of this nature. This document is the first version of the VITALISE DMP submitted at month M06 of the project. Consequently, the datasets presented at this stage represent a preview of the data that may be collected. In the later stage of the project, we expect that there may be some changes regarding the content of the datasets. Important changes occurring due to the inclusion or exclusion of a dataset will be followed by changes in consortium policies or external factors and the creation of an updated version of the DMP. To ensure that the DMP will be implemented as expected regular checks on the status of the data will be carried out on a schedule. The main principals of the project, though, are expected to be maintained as is until the end, thus delineating the principal axes of the overall DMP. The final version of the DMP will be submitted at month M30 of the VITALISE project in deliverable D1.5 “Data Management Plan (final version)”.
title: Estimation, Testing, and Monitoring of Generalized Autoregressive Conditionally Heteroskedastic Time Series
Creators: name: Zhang, Aonan
Publisher: name: Utah State University
Year: 2005

description: We study in this dissertation Generalized Autoregressive Conditionally Heteroskedastic (GARCH) time series. The research focuses on squared GARCH sequences. Our main results are as follows:
1. We compare three methods of constructing confidence intervals for sample autocorrelations of squared returns modeled by models from the GARCH family. We compare the residual bootstrap, block bootstrap and subsampling methods. The residual bootstrap based on the standard GARCH(l,1) model is seen to perform best. Confidence intervals for cross-correlations of a bivariate GARCH model are also studied.
2. We study a test to discriminate between long memory and volatility changes in financial returns data. Finite sample performance of the test is examined and compared using various variance estimators. The Bartlett kernel estimator with truncation lag determined by a calibrated bandwidth selection procedure is seen to perform best. The testing procedure is robust to various GARCH-type models.
3. We propose several methods of on-line detection of a change in unconditional variance in a conditionally heteroskedastic time series. We follow a paradigm in which the first m observations are assumed to follow a stationary process and the monitoring scheme has asymptotically controlled probability of falsely rejecting the null hypothesis of no change. Our theory is applicable to broad classes of GARCH-type time series and relies on a strong invariance principle which holds for the squares of observations generated by such models. Practical implementation of the procedures is proposed and the performance of the methods is investigated by a simulation study.

description: A new class of exclusion type processes acting in continuum with synchronous updating is introduced and studied. Ergodic averages of particle velocities are obtained and their connections to other statistical quantities, in particular to the particle density (the so called Fundamental Diagram) is analyzed rigorously. The main technical tool is a "dynamical" coupling applied in a nonstandard fashion: we do not prove the existence of the successful coupling (which even might not hold) but instead use its presence/absence as an important diagnostic tool. Despite that this approach cannot be applied to lattice systems directly, it allows to obtain new results for the lattice systems embedding them to the systems in continuum. Applications to the traffic flows modelling are discussed as well.

Orion Bar as a window to the evolution of PAHs

description: We investigate the mid-infrared (IR) emission in the Orion Bar photodissociation region, using archival photometric and spectroscopic observations from UKIRT, Spitzer, ISO, and SOFIA telescopes. Specifically, we consider flux densities of the emission bands at 3.3, 3.4, 3.6, 6.6, 7.7, 11.2~$μ$m in several locations and a spectrum from 3 to 45~$μ$m in one location. We study the behaviour of band flux ratios, which are sensitive to external conditions, as revealed by their variations with the distance from an ionizing source. Assuming that the mid-IR emission arises mostly from polycyclic aromatic hydrocarbons (PAHs), and that a weak emission feature at 3.4~$μ$m is related to PAHs with extra hydrogen atoms (H-PAHs), we trace variations of the ratios using a model for PAH evolution. Namely, we estimate how populations of PAHs of different sizes, hydrogenation and ionization states change across the Orion Bar over a time interval approximately equal to its lifetime. The obtained ensembles of PAHs are further used to calculate the corresponding synthetic spectra and band flux densities. The model satisfactorily describes the main features of the ratios $I_{3.6}/I_{11.2}$, $I_{7.7}/I_{11.2}$, $I_{7.7}/I_{3.6}$ and $I_{3.3}/I_{3.4}$. We conclude that the best coincidence between modelling and observations is achieved if C loss of PAHs is limited by the number of carbon atoms $N_{\rm C}=60$, and the band at 3.4~$μ$m may indeed be attributed to H-PAHs. We confirm that large cations dominate at the surface of the PDR but small neutral PAHs and anions are abundant deeper in the molecular cloud.

description: The Expectation Maximization (EM) algorithm is the default algorithm for inference in latent variable models. As in any other field of machine learning, applications of latent variable models to very large datasets make the use of advanced parallel and distributed architectures mandatory. This paper introduces FedEM, which is the first extension of the EM algorithm to the federated learning context. FedEM is a new communication efficient method, which handles partial participation of local devices, and is robust to heterogeneous distributions of the datasets. To alleviate the communication bottleneck, FedEM compresses appropriately defined complete data sufficient statistics. We also develop and analyze an extension of FedEM to further incorporate a variance reduction scheme. In all cases, we derive finite-time complexity bounds for smooth non-convex problems. Numerical results are presented to support our theoretical findings, as well as an application to federated missing values imputation for biodiversity monitoring.

description: Abstract

The objective of this study is to determine the fungal flora present in the air and on the foliar parts of strawberry plants, varieties Festival and Camarosa, cultivated in the Moulay Bouselham region (North-ouest Morocco), and to highlight the influence of microclimate on their development. Surveys were carried out on three farms under irrigated shelter, where microclimatic conditions, such as temperature and relative humidity, were measured and analysed. The results reveal significant fungal diversity, influenced by microclimatic conditions. In fact, variations in temperature and relative humidity have a significant influence on the distribution of fungal species. Botrytis cinerea reached high levels of contamination, with 8712.7 CFU/m² in MV1 and 8492.6 CFU/m² in GV1. Cladosporium cladosporioides was also very present, with values reaching 17,802.9 CFU/m² in SV3 and 10,788.7 CFU/m² in MV1, while Fusarium oxysporum showed a more limited presence, with values of 440.3 CFU/m² in GV2 and 377.4 CFU/m² in GV3. Temperatures were ranged from 17.44°C to 28.26°C, and relative humidity between 50.96% and 61.26%. These climatic conditions favoured fungal contamination. Botrytis cinerea was very present in the leaves of GV1 (90%) and MV1 (82%), while Podosphaera aphanis was dominant in MV3 (56%) and GV3 (56%). Cladosporium cladosporioides was strongly present in MV3 (49%) and SV2 (45%). These results highlight the importance of microclimate management and agricultural practices in reducing losses due to fungal diseases in strawberry cultivation.

description: We propose an entanglement beam splitter (EBS) using a quantum-dot spin in a double-sided optical microcavity. In contrast to the conventional optical beam splitter, the EBS can directly split a photon-spin product state into two constituent entangled states via transmission and reflection with high fidelity and high efficiency (up to 100 percent). This device is based on giant optical circular birefringence induced by a single spin as a result of cavity quantum electrodynamics and the spin selection rule of trion transition (Pauli blocking). The EBS is robust and it is immune to the fine structure splitting in a realistic quantum dot. This quantum device can be used for deterministically creating photon-spin, photon-photon and spin-spin entanglement as well as a single-shot quantum non-demolition measurement of a single spin. Therefore, the EBS can find wide applications in quantum information science and technology.

title: Minimal Nodal Domains for Strictly Elliptic Partial Differential Equations with Homogeneous Boundary Conditions
Creators: name: Miller, Charles E.
Publisher: name: Utah State University
Year: 2006

description: This work presents a proof of the dependence of the first eigenvalue for uniformly elliptic partial differential equations on the domain in a less abstract setting than that of Ivo Babushka and Rudolf Vyborny in 1965. The proof contained here, under rather mild conditions on the boundary of the domain, �Ω, demonstrates that the first eigenvalue of elliptic partial differential equation
[ �� + �� = 0 �� Ω
[ � = 0 �� �Ω
depends continuously on the domain in the following sense. If a sequence of domains is such that, then the corresponding first eigenvalues satisfy is the first eigenvalue for
[ �� + �� = 0 �� Ω
[ � = 0 �� �Ω
The work also reviews and utilizes the Sturmian comparison results of John G. Heywood, E. S. Noussair, and Charles A. Swanson. For a continuously parameterized family of domains, say with μ ∈ = [a, b], the continuous dependence of the eigenvalue on the domain combined with the Sturmian comparison results provide a theorem that insures, under certain conditions, that the elliptic partial differential equation
[ �� = 0 �� Ω
[ � = 0 �� �Ω
has a solution which is positive on a nodal domain That is there is a least value of μ [a, b] so that a positive solution u exists for
[ �� = 0 �� Ωμ
[ � = 0 �� �Ωμ
Beyond these results the work contains a theorem that shows for certain types of domains, rectangles in , among them, that there is a critical dimension smaller than which, no solution to the problem
[ �� + �� = 0 �� Ω
[ � = 0 �� �Ω
exists when the eigenvalue is fixed.
During the investigations taken up in this work, certain observations were made regarding linear approximations to eigenvalue problems in R2 using a standard numerical approximation scheme. One such observation is that if a linear approximation to an eigenvalue problem contains an incorrect estimate for an eigenvalue, the resulting graphical approximation seems to betray whether or not the estimate was low or high. The observations made do not appear to exist in the literature.
SiO Outflow Signatures Toward Massive Young Stellar Objects with Linearly Distributed Methanol Masers

description: Methanol masers are often found in linear distributions, and it has been hypothesized that these masers are tracing circumstellar accretion disks around young massive stars. However, recent observations in H2 emission have shown what appear to be outflows at similar angles to the maser distribution angles, not perpendicular as expected in the maser-disk scenario. The main motivation behind the observations presented here is to determine from the presence and morphology of an independent outflow tracer, namely SiO, if there are indeed outflows present in these regions and if they are consistent or inconsistent with the maser-disk hypothesis. For ten sources with H2 emission we obtained JCMT single dish SiO (6-5) observations to search for the presence of this outflow indicator. We followed up those observations with ATCA interferometric mapping of the SiO emission in the (2-1) line in six sources. The JCMT observations yielded a detection in the SiO (6-5) line in nine of the ten sources. All of the sources with bright SiO lines display broad line wings indicative of outflow. A subset of the sources observed with the JCMT have methanol maser velocities significantly offset from their parent cloud velocities, supporting the idea that the masers in these sources are likely not associated with circumstellar disks. The ATCA maps of the SiO emission show five of the six sources do indeed have SiO outflows. The spatial orientations of the outflows are not consistent with the methanol masers delineating disk orientations. Overall, the observations presented here seem to provide further evidence against the hypothesis that linearly distributed methanol masers generally trace the orientations of circumstellar disks around massive young stars.

description: The recent associations of neutrinos with blazars require the efficient interaction of relativistic protons with ambient soft photon fields. However, along side the neutrinos gamma-ray photons are produced which interact with the same soft photon fields producing electron-positron pairs. The strength of this cascade has significant consequences on the photon spectrum in various energy bands and puts severe constraints on the pion and neutrino production. In this study, we discuss the influence of the external thermal photon fields (accretion disk, broad-line region, and dusty torus) on the proton-photon interactions employing a newly developed time-dependent one-zone hadro-leptonic code (OneHaLe). We present steady-state cases, as well as a time-dependent case, where the emission region moves through the jet. Within the limits of this toy study, the external fields can disrupt the ``usual'' double-humped blazar spectrum. Similarly, a moving region would cross significant portions of the jet without reaching the previously-found steady states.

description: Abstract

Prolactin receptor gene can influence the reproductive traits of chickens, such as broodiness and egg production. The aim of the study was to assess polymorphism and association of prolactin receptor genes with the reproductive traits of the Nigerian indigenous chicken ecotypes. A total of 100 chickens drawn from four different groups/populations of chickens were provided for the study. The chickens which comprised of laying hens only were tagged from Hen 1 to Hen 100. For further identification, hen 1 to hen 35 were tagged as population 1, and were drawn from Generation (G) 7, Heavy ecotype selected (35 hens). Hen 36 to hen 72 were tagged as population 2, and were drawn from G 8, Heavy ecotype selected (37 hens). Hen 73 to hen 90 were tagged as population 3, and were drawn from Light ecotype unselected (18 hens), and hen 91 to hen 100 were tagged as population 4, and were drawn from Heavy ecotype unselected (10 hens). Generations G7 and G8 are groups of the Nigerian heavy local chicken ecotype that have undergone seven and eight generations of selection using selection index. Two (2) blood samples were randomly collected from each population with the aid of sterile syringes and needles onto a Whatman FTA card and allowed to air dry for DNA extraction. The DNA was extracted using the GenoAid extraction protocol. PCR was conducted and the product was then viewed on 2% agarose gel. The sequence results showed that a total of 206 base pairs (bp) screened for prolactin receptor PRLR5a gene did not have any polymorphism across the samples studied. However, on prolactin receptor PRLR6 gene, 195 base pairs were screened and variation occurred at polymorphic site 47bp with nucleotide base “A” transcribed to “G”, and the possible genotypes were “AG” and “GG”. The phylogenetic tree analysis clustered the samples into two branches and showed that individuals with “GG” genotype performed better than those birds with AG genotype in the reproductive traits considered. It was therefore, concluded that prolactin receptor PRLR6 gene was polymorphic at site 47 bp and positively associated with the reproductive traits: body weight at first egg, body weight at 16th week of egg production, total egg number and average egg weight. The mutated genotype (GG) showed superior performance over the normal genotype (AG) of the Nigerian indigenous chicken ecotypes.

description: A quantum memory that can store quantum states faithfully and retrieve them on demand has wide applications in quantum information science. An efficient quantum memory in the microwave regime working alongside quantum processors based on superconducting quantum circuits may serve as an important architecture for quantum computers. Here we realize on-demand storage and retrieval of weak coherent microwave photon pulses at the single-photon level. We implement a superconducting multi-resonator quantum memory which is composed of a set of frequency-tunable coplanar transmission line (CPW) resonators. By dynamically tuning the resonant frequencies of the resonators, we achieve tunable memory bandwidth from 10 MHz to 55 MHz, with an overall storage efficiency up to 12 % with well preserved phase coherence. We further demonstrate on-demand storage and retrieval of a time-bin flying qubit. This result opens up a prospect to integrate our chip-based quantum memory with the state-of-the-art superconducting quantum circuit technology for quantum information processing.

description: Abstract

This study aims to investigate the strategy of issuing regional bonds as a potential financial instrument to support regional economic development through the capital market, focusing on the perspective of regional autonomy in Indonesia. Through an in-depth analysis of local bond issuance regulations and practices, this study will explore how local governments can leverage these instruments to strengthen local funding sources to support infrastructure development and other economic initiatives. In addition, the study will also identify the main challenges local governments face in using regional bonds as an alternative to financing, including complex regulations, institutional readiness, and risk factors such as moral hazard and potential corruption. In particular, this study will reconstruct the legal framework that regulates the issuance of regional bonds by highlighting aspects that need to be strengthened or adjusted to facilitate the effective use of regional bonds in accordance with the principle of regional autonomy. Thus, this research is expected to provide in-depth insights into public policy in facilitating the use of regional bonds to strengthen regional financial autonomy and encourage sustainable local economic growth.

Their high surface area (ca. 1000 m2/g), well-structured porosity, versatile possibilities for obtaining nanocarriers of different morphologies, pore diameters and surface characteristics, allow construction of different nanosystems for efficient cancer targeting. Methods: In this study, the potential of mesoporous silica nanoparticles for applications in targeted treatment of cancer is presented. Results: Our team focuses on construction and surface functionalization of MSN with different moieties for active cancer-targeting. The drug release process can be also controlled through different externally applicable stimuli (eg. light irradiation, magnetic field), or upon exposure to intratumoral conditions such as weakly acidic environment, the elevated concentration of glutathione or other cancer biomarkers. In addition, MSN can be decorated with specific moieties to enable imaging of cancer (eg. magnetic resonance imaging (MRI)), which would enable simultaneous cancer therapy and diagnostics (theranostics). Conclusions: Mesoporous silica nanoparticles have substantial potentials for enhancing the efficacy and precision of cancer treatment.

description: We derive semiclassical laser equations valid in all orders of nonlinearity. With the help of a diagrammatic representation, the perturbation series in powers of electric field can be resummed in terms of a certain class of diagrams. The resummation makes it possible to take into account a weak effect of population pulsations in a controlled way, while treating the nonlinearity exactly. The proposed laser theory reproduces the all-order nonlinear equations in the approximation of constant population inversion and the third-order equations with population-pulsation terms, as special cases. The theory can be applied to arbitrarily open and irregular lasers, such as random lasers.

description: It is known that massive black holes have a profound effect on the evolution of galaxies, and possibly on their formation by regulating the amount of gas available for the star formation. However,  how black hole and galaxies communicate is still an open problem, depending on how much of the energy released interacts with the circumnuclear matter. 
In the last years, most studies of feedback have primarily focused on AGN jet/cavity systems in the most massive galaxy clusters. This thesis intends to investigate  the feedback phenomena in radio--loud  AGNs  from a different perspective studying isolated radio galaxies, through high-resolution spectroscopy. In particular one NLRG and three BLRG are studied, searching for warm gas, both in emission and absorption, in the soft X-ray band. I show that the soft spectrum of 3C33  originates from gas photoionized by the central engine.  I found  for the first time WA in 3C382 and 3C390.3.  I show that the observed warm emitter/absorbers is  not uniform and probably located in the NLR. 
The detected WA is slow  implying a mass outflow rate and kinetic luminosity always well below 1% the L(acc) as well as the P(jet).
Finally the radio--loud properties are compared with those of type 1 RQ AGNs. 
A positive correlation is found between the mass outflow rate/kinetic luminosity, and the radio loudness. 
This seems to suggest that the presence of a radio source (the jet?)  affects the distribution of the absorbing gas. 
Alternatively,  if the gas distribution is similar in Seyferts and radio galaxies,  the M(out)  vs rl relation could simply indicate a major  ejection  of matter in the form of wind in powerful radio AGNs.

description: Recently, computational modelling became a very important research tool that enables us to study problems that for decades evaded scientific analysis. Evolutionary systems are certainly examples of such problems: they are composed of many units that might reproduce, diffuse, mutate, die, or in some cases for example communicate. These processes might be of some adaptive value, they influence each other and occur on various time scales. That is why such systems are so difficult to study. In this paper we briefly review some computational approaches, as well as our contributions, to the evolution of ecosystems and language. We start from Lotka-Volterra equations and the modelling of simple two-species prey-predator systems. Such systems are canonical example for studying oscillatory behaviour in competitive populations. Then we describe various approaches to study long-term evolution of multi-species ecosystems. We emphasize the need to use models that take into account both ecological and evolutionary processes. Finally, we address the problem of the emergence and development of language. It is becoming more and more evident that any theory of language origin and development must be consistent with darwinian principles of evolution. Consequently, a number of techniques developed for modelling evolution of complex ecosystems are being applied to the problem of language. We briefly review some of these approaches.

title: Structural Properties of Formal Polynomial Algebras in Noncommuting or Nonassociating Indeterminates
Creators: name: Ballif, Serge C.
Publisher: name: Utah State University
Year: 2007

description: In order to enlarge the class of equations provided by traditional polynomials over a binary algebra A to a more useful class of equations, we introduce polynomials in noncommuting or nonassociating indeterminates. We discuss algebraic properties of these formal polynomial algebras and their accompanying polynomial function algebras. We present certain basis results for polynomial algebras, which are used to address the question of zero divisors in a polynomial algebra. We give an analog of the remainder theorem and the factor theorem for polynomials. Particular emphasis is placed on showing the difference between polynomials and polynomial functions. We also provide a brief discussion of polynomial composition and formal derivatives.

description: Inclusive production cross sections of the possible exotic state X(3872) in proton-proton, pionp-roton and proton-antiproton collisions are calculated using a statistical based model, which is previously used to describe inclusive charmed and bottomed hadron production cross sections in the low energy region. With the extensions made here, the model is capable to include tetraquarks as well, using the diquark picture of tetraquarks. The evaluated cross section ratio of $Ψ(2S)$ and $X(3872)$ at $\sqrt{s}=7$ TeV agrees well with the measured value.

description: Abstract

Ship accidents are one of the main risks in shipping activities. Ship accidents can cause enormous material and non-material losses, including casualties. This study aims to analyze the factors that affect ship accidents and compile recommendations for prevention from the aspect of Navigation-Shipping Aids. The rate of passenger ship accidents in Indonesia is currently still relatively high. The research method in this study uses the normative legal research method, which examines laws and regulations and legal literature to answer legal problems. The results of this study show that in the case of ship accidents, legal responsibility can fall on the ship owner or other parties related to negligence or failure in maintaining navigation-shipping aids. This article provides an in-depth understanding of relevant legal procedures and the importance of applying navigation technology to prevent ship accidents. The conclusions of the analysis show that the factors affecting ship accidents and their prevention efforts from the aspects of navigation-navigation aids can be improved by ensuring the classification of navigational aids and the role of law in regulating their use.

description: The calculations of the alpha decay half-lives of some Polonium isotopes in the mass range 186 - 218 have been carried out using the Wentzel-Kramers-Brillouin (WKB) semiclassical approximation. The alpha-nucleus effective potential used contains the Coulomb potential, centrifugal potential, and the nuclear potential. The nuclear potential is obtained via the double folding model, with the microscopic NN effective interactions derived from relativistic mean field theory Lagrangian (termed R3Y). Different parametrizations of the R3Y interactions have been employed in the computation of the nuclear potentials. The results obtained using the R3Y NN interactions are compared with the ones obtained using the famous Michigan-3-Yukawa (M3Y) interactions. The use of density-dependent NN interaction is also considered. When compared to available experimental data, there are improvements in the results when density-dependent interaction potentials are used compared to when density-independent interactions are employed.

description: Digital sources are more prevalent than ever but effectively using them can be challenging. One core challenge is that digitized sources are often distributed, thus forcing researchers to spend time collecting, interpreting, and aligning different sources. A knowledge graph can accelerate research by providing a single connected source of truth that humans and machines can query. During two design-test cycles, we convert four data sets from the historical maritime domain into a knowledge graph. The focus during these cycles is on creating a sustainable and usable approach that can be adopted in other linked data conversion efforts. Furthermore, our knowledge graph is available for maritime historians and other interested users to investigate the daily business of the Dutch East India Company through a unified portal.

description: Conditional coding is an application of Markov Chain Monte Carlo methods for sampling from conditional distributions. It is applied here to the problem of estimating the parameters of a computer-simulated pattern of fractures in an isomorphic, homotropic material under plane strain. We investigate the theory and procedures of conditional coding and show the viability of the technique by its application.

description: Abstract

As the world witnesses the ongoing War on Gaza, characterized by mass displacement and widespread destruction that is never precedented in modern human history, this situation prompts urgent questions about the future mapping of reconstruction efforts. The challenges, timelines, key actors, and crucial elements for effective, human-centred recovery become complex, yet essential to be tackled with defined problem-solving techniques to avoid fatigue of donors.  The continued military campaign has resulted so far in over 38,387 Palestinian deaths, more than 92,058 injuries, and the destruction of over 60% of buildings, making the area virtually uninhabitable. While the extent of future destruction remains uncertain, planning for post-conflict reconstruction is vital. This involves learning from past efforts and challenges to shape effective future strategies. Taking into consideration that Gaza has been under prolonged occupation and wars in the last two decades that ended with multiple incomplete reconstruction attempts. The authors study the unprecedented destruction since October 7th, what type of radical recovery plan is needed for reconstruction to achieve tangible results, including the parallel quality of life needs. The study aims to contribute to identifying the new needs for the reconstruction of Gaza by examining its context after October 7th, 2023 and comparing the past strategies and other post-war rebuilding efforts. The implication of the study is s emphasises key factors that need to be taken into consideration when shaping Gaza's upcoming reconstruction strategies by all the concerned players.
