description: Liquid Argon (LAr) is one of the most widely used scintillators in particle detection, due to its low cost, high availability and excellent scintillation properties. A large number of experiments in the neutrino sector are based around using LAr in one or more Time Projection Chambers (TPCs), leading to high resolution three-dimensional particle reconstruction. In this paper, we review and summarise a number of these Liquid Argon Time Projection Chamber (LArTPC) experiments, and briefly describe the specific technologies that they currently employ. This includes single phase LAr experiments (ICARUS T600, MicroBooNE, SBND, LArIAT, DUNE-SP, ProtoDUNE-SP, ArgonCube and Vertical Drift) and dual phase LAr experiments (DUNE-DP, WA105, ProtoDUNE-DP and ARIADNE). We also discuss some new avenues of research in the field of LArTPC readout, which show potential for wide-scale use in the near future.

description: We present results of three-dimensional (3D), radiation-magnetohydrodynamics (MHD) simulations of core-collapse supernovae in full general relativity (GR) with spectral neutrino transport. In order to study the effects of the progenitor’s rotation and magnetic fields, we compute three models, where the precollapse rotation rate and magnetic fields are included parametrically to a 20 M⊙ star. While we find no shock revival in our two nonmagnetized models during our simulation times (∼500 ms after bounce), the magnetorotational (MR) driven shock expansion immediately initiates after bounce in our rapidly rotating and strongly magnetized model. We show that the expansion of the MR-driven flows toward the polar directions is predominantly driven by the magnetic pressure, whereas the shock expansion toward the equatorial direction is supported by neutrino heating. Our detailed analysis indicates that the growth of the so-called kink instability may hinder the collimation of jets, resulting in the formation of broader outflows. Furthermore, we find a dipole emission of lepton number, only in the MR explosion model, whose asymmetry is consistent with the explosion morphology. Although it is similar to the lepton number emission self-sustained asymmetry (LESA), our analysis shows that the dipole emission occurs not from the proto–neutron star convection zone but from above the neutrino sphere, indicating that it is not associated with the LESA. We also report several unique neutrino signatures, which are significantly dependent on both the time and the viewing angle, if observed, possibly providing rich information regarding the onset of the MR-driven explosion.

description: We theoretically investigate the out-of-equilibrium dynamics in a binary Bose-Einstein condensate confined within two-dimensional box potentials. One species of the condensate interacts with a pair of oppositely wound, but otherwise identical Laguerre-Gaussian laser pulses, while the other species is influenced only via the interspecies interaction. Starting from the Hamiltonian, we derive the equations of motion that accurately delineate the behavior of the condensates during and after the light-matter interaction. Depending on the number the helical windings (or the magnitude of topological charge), the species directly participating in the interaction with lasers is dynamically segmented into distinct parts which collide together as the pulses gradually diminish. This collision event generates nonlinear structures in the related species, coupled with the complementary structures produced in the other species, due to the interspecies interaction. The long-time dynamics of the optically perturbed species is found to develop the Kolmogorov-Saffman scaling law in the incompressible kinetic energy spectrum, a characteristic feature of the quantum turbulent state. However, the same scaling law is not definitively exhibited in the other species. This study warrants the usage of Laguerre-Gaussian beams for future experiments on quantum turbulence in Bose-Einstein condensates.

description: In this article we report on the experimental realization of dimensional crossover phenomena in the chain compound PrBa$_2$Cu$_4$O$_8$ using temperature, high magnetic fields and disorder as independent tuning parameters. In purer crystals of PrBa$_2$Cu$_4$O$_8$, a highly anisotropic three-dimensional Fermi-liquid state develops at low temperatures. This metallic state is extremely susceptible to disorder however and localization rapidly sets in. We show, through quantitative comparison of the relevant energy scales, that this metal/insulator crossover occurs precisely when the scattering rate within the chain exceeds the interchain hopping rate(s), i.e. once carriers become confined to a single conducting element.

description: In this note we investigate the last passage percolation model in the presence of macroscopic inhomogeneity. We analyze how this affects the scaling limit of the passage time, leading to a variational problem that provides an ODE for the deterministic limiting shape of the maximal path. We obtain a sufficient analytical condition for uniqueness of the solution for the variational problem. Consequences for the totally asymmetric simple exclusion process are discussed.

Total of 16 composite haplotypes were identified and the number of haplotypes per population ranged from 6 to 8. Three haplotypes were shared by all five populations and had similar frequencies ranging from 0.100 to 0.450. One haplotype was observed in 4 populations, two haplotypes in 3 populations and one haplotype was shared by 2 populations. Nine.rare.haplotypes were found in 4 populations, at frequencies ranging from 0.025 to 0.075. The highest number of rare haplotypes, three, was observed in the samples from the rivers Sl:upia and Pars(,_ta.. No rare haplotypes were detected in the river Wieprza. All populations were fixed at one morph for the ND-I segment digested with Hinfl.
Large Number, Dark Matter, Dark Energy, and the Superstructures in the Universe (with Extension)

description: Since there are dark matter particles (neutrino) with mass about 10^(-1)eV in the universe, the superstructures with a scale of 10^(19) solar mass [large number A is about 10^(19)] appeared around the era of the hydrogen recombination. The redshift z distributions of quasars support the existence of superstructures. Since there are superstructures in the universe, it is not necessary for the hypothesis of dark energy. While neutrino is related to electro-weak field, the fourth stable elementary particles (delta particle) with mass about 10^(0)eV to 10^(1)eV is related to gravitation-"strong" field, which suggests p + anti(p)--> n/anti(n) + anti(delta particle)/(delta particle) and that some new meta-stable baryons appeared near the TeV region. Therefore, a twofold standard model diagram is proposed, and related to many experiment phenomena: The new meta-stable baryons' decays produce delta particles, which are helpful to explain the Dijet asymmetry phenomena at LHC of CERN, the different results for the Fermilab's data peak, etc; However, according to the (B-L) invariance, the sterile "neutrino" from "the event excess in MiniBooNe" can not be the fourth neutrino but rather the delta particle; We think that the delta particles are related to the phenomenon about neutrinos FTL, and that anti-neutrinos are faster than neutrinos. FTL is also related to the cosmic inflation, singular point disappearance, and abnormal red shift of SN Ia. Some experiments and observations are suggested. In the Extension section, we clarify "mass tree", our finite universe, cosmic dual expansions, dual SM etc. And the LHC can look for new particles with decay products graviton/delta particle and new interaction indeed.

Quantum pathology of static internal imperfections in flawed quantum computers

Subjects: subject: Quantum Physics (quant-ph)

description: Even in the absence of external influences the operability of a quantum computer (QC) is not guaranteed because of the effects of residual one- and two-body imperfections. Here we investigate how these internal flaws affect the performance of a quantum controlled-NOT (CNOT) gate in an isolated flawed QC. First we find that the performance of the CNOT gate is considerably better when the two-body imperfections are strong. Secondly, we find that the largest source of error is due to a coherent shift rather than decoherence or dissipation. Our results suggest that the problem of internal imperfections should be given much more attention in designing scalable QC architectures.

description: The aim of this dissertation is to present the issues in the field of substantive incompetence οf a court, specifically under the scope of legal remedies. This study attempts to thoroughly investigate, profoundly analyze and record all the problems resulting from the referral of a case to a court without substantive competence, the way it used to apply and the way it currently applies. In this context, this thesis does not answer the question of under which court falls each crime, but aims to an overall understanding of the inextricably connection between the referral of a case to a court without substantive competence, the enforcement of procedural coercive measures, the remedies against this judgement and the results of them (remedies). The following issues are also set out and analyzed: 1) Which is the exact meaning of the case law assumption "The judjement of the court under the art. 120 par. 2 of Greek Criminal Procedure Code is in place of a referral bill of indictment 2) This judjement is an adjudication or an idictment 3) what legal remedies provide defence against that judjement. These multiannual issues obscure the judicial reasoning and highliht the necessity of the holistic study of this field.

description: There is a deep astrophysical interest in the structure of $^{19}$F states close to the alpha decay threshold. The nuclear structure of these states is important for understanding of the development of $α$ clustering in the $^{20}$Ne region. Emergence of clustered states and generally states that favor coupling to reaction channels near the corresponding decay thresholds is currently of special interest in theoretical physics. Excitation function for $^{15}$N($α$,$α$) elastic scattering was measured by the TTIK method. These new data together with old, high energy resolution data, were analyzed using the R matrix approach. $^{19}$F nuclear structure was calculated using configuration interaction methods with the recently developed effective interaction Hamiltonian. The parameters of broad low spin $\ell = 0$ and 1 relative partial wave resonances close to the $α$ decay threshold in $^{19}$F were identified. Detailed theoretical analysis was carried out identifying all states coupled to the $\ell = 0$ and 1 alpha cluster channels. Considering hierarchy of states with different harmonic oscillator shell excitations allows to evaluate coupling to the alpha channels with different number of nodes in the relative wave function and helps to explain the distribution of the clustering strength and emergence of broad clustering resonances. Comparison of clustering in $^{20}$Ne into $^{16}$O+$α$ and consideration of spin-orbit splitting of the $^{15}$N+$α$ channel provides additional evidence. Detailed analysis of new and old experimental data allows to identify a series of $α$ clustering resonances in $^{19}$F and to assess the distribution of the clustering strength which is of importance to questions of astrophysics and for theoretical understanding of many-body physics and emergence of clustering in loosely bound or unstable nuclei.

description: The present thesis constitutes a pioneering research that introduces automated methods in order to study of the protein network of the epidermal growth factor receptor (EGFR) pathway. EGFR pathway exhibits biological complexity with non-linear interactions of large numbers of proteins and extensive overlaps among them. This thesis aims to develop and utilize a computational model for the EGFR pathway, in order to automatically generate accurate time series that describe the variations of the concentrations of different proteins. An additional goal is to create a model (graph) that represents the original pathway with the utmost accuracy. Time series analysis and accurate graph representation of the original network could reveal its structure and dynamics, as well as other network details that are impossible to be discovered experimentally, and even predict network behavior under
In-pit crushing and conveying as an alternative to an all truck system in open pit mines
Creators: name: Radlowski, Jacek K.
Publisher: name: University of British Columbia
Year: 2010

description: The material transport system in an open pit mine significantly affects the capital and operating costs. All truck haulage is the most common and is a reliable and flexible transport system. On the other hand, this system is very expensive and can cost up to 50% of total mining costs. Its cost is continuously increasing due to the inflation of the fuel, tire, and labour expenditures. In-pit crushing and conveying is an alternative transport system which requires a higher initial investment but gives substantial savings in operating costs. An evaluation of the all truck system versus the in-pit crushing and conveying system has been performed by means of a simulation of both transport systems in the same mine model. Results of the simulation and the data obtained from the feasibility studies provided input for an economic comparison of the alternative transport systems. A cash flow analysis showed that the in-pit crushing and conveying system was competitive with the all truck system, giving a payback within four years and resulting in total costs over 30% lower than those of an all truck system. Three computer programs, written by the author, have been used to analyse the mine model: (1) Open Pit Simulation Program - to model a hypothetical mine and simulate its haulage operation over the mine life, (2) Off-Highway Truck Simulation Program - to simulate the truck haulage on average annual routes in terms of the operating time and fuel consumption for the estimation of the truck fleet size and the fuel cost, (3) Cash Flow Analysis Calculation Program - to compare costs of the alternative transport systems over the whole period of a mine life.

description: Many practical combustion systems such as those in rockets, gas turbines, and internal combustion engines operate under high pressures that surpass the thermodynamic critical limit of fuel-oxidizer mixtures. These conditions require the consideration of complex fluid behaviors that pose challenges for numerical simulations, casting doubts on the validity of existing subgrid-scale (SGS) models in large-eddy simulations of these systems. While data-driven methods have shown high accuracy as closure models in simulations of turbulent flames, these models are often criticized for lack of physical interpretability, wherein they provide answers but no insight into their underlying rationale. The objective of this study is to assess SGS stress models from conventional physics-driven approaches and an interpretable machine learning algorithm, i.e., the random forest regressor, in a turbulent transcritical non-premixed flame. To this end, direct numerical simulations (DNS) of transcritical liquid-oxygen/gaseous-methane (LOX/GCH4) inert and reacting flows are performed. Using this data, a priori analysis is performed on the Favre-filtered DNS data to examine the accuracy of physics-based and random forest SGS-models under these conditions. SGS stresses calculated with the gradient model show good agreement with the exact terms extracted from filtered DNS. The accuracy of the random-forest regressor decreased when physics-based constraints are applied to the feature set. Results demonstrate that random forests can perform as effectively as algebraic models when modeling subgrid stresses, only when trained on a sufficiently representative database. The employment of random forest feature importance score is shown to provide insight into discovering subgrid-scale stresses through sparse regression.

description: No abstracts are to be cited without prior reference to the author.Atlantic cod along and off the coast of northern Norway have over the last years been analyzed for variation at the scnDNA locus coding for synaptophysin, an integral synaptic vesicle membrane protein. After 60 subsamples and approximately 3000 specimens have been examined, a profound divergence between two groups of cod has been substantiated. There is reason to believe that these two groups represent what has been characterized as coastal versus Northeast Arctic cod, a suggestion that is supported by otolith readings. Both inshore and offshore there is in general great stability in allele frequencies among adults and fry in consecutive years, but always great divergence when offshore and inshore samples are compared. Fjords with direct access to open ocean water exhibit significant stratification in allele frequencies, both horizontally and vertically. This small scale geographic variation seems to be coupled to different settling strategies. In areas where both groups are found, 0-group individuals of the ·dominant coastal cod genotype seem to settle at shallow water, whereas fry of the dominant NE-arctic genotype is found pelagically or at deep water

description: In this work we study modifications in the Aharonov-Bohm effect for relativistic spin 1/2 particles due to the noncommutativity of spacetime in $2 + 1$ dimensions. The noncommutativity gives rise to a correction to the Aharonov-Bohm potential which is highly singular at the origin, producing divergences in a perturbative expansion around the usual solution of the free Dirac equation. This problem is surmounted by using a perturbative expansion around the exact solution of the \textit{commutative} Aharonov-Bohm problem. We calculate, in this setting, the scattering amplitude and the corrections to the differential and total cross sections for a spin 1/2 particle, in the small-flux limit.

Among other things, these polluters differ by the amount of helium they spread in the surrounding medium. In this study we investigate whether the present-day photometric method used to infer the helium content of multiple populations indeed gives the true value or underestimates it by missing very He-rich, but rare stars. We focus on the specific case of NGC6752. We compute atmosphere models and synthetic spectra along isochrones produced for this cluster for a very broad range of He abundances covering the predictions of different pollution scenarios, including the extreme case of the fast-rotating massive star (FRMS) scenario. We calculate synthetic photometry in HST filters best suited to study the helium content. We subsequently build synthetic clusters with various distributions of stars. We finally determine the maximum helium mass fraction of these synthetic clusters using a method similar to that applied to observational data. We build toy models of clusters with various distributions of multiple populations and ensure that we are able to recover the input maximum Y. We then build synthetic clusters with the populations predicted by the FRMS scenario and find that while we slightly underestimate the maximum Y value, we are still able to detect stars much more He-rich than the current observed maximum Y. It is easier to determine the maximum Y on main sequence stars than on red giant branch stars, but qualitatively the results are unaffected by the sample choice. We show that in NGC6752 it is unlikely that stars more He-rich than the current observational limit of about 0.3 are present.

description: No abstracts are to be cited without prior reference to the author.Allozymes were the first molecular markers to be used in aquaculture genetics. Low levels of variability and stringent sampling requirements restricted usage. With the isolation of DNA loci with large numbers of alleles (chiefly minisatellite and micro satellite loci), and also other nuclear DNA markers and mitochondrial DNA, many novel applications in aquaculture have become possible. In this paper the attributes of these markers are discussed and applications described, with consideration of the most appropriate marker/s for each application. Current applications include species and hybrid identification, and various uses at the sub-specific level, viz. recording genetic changes in aquaculture strains relative to their wild progenitors; identification as to family in farming or stocking situations; using molecular markers as genetic tags enabling individual identification (so-called genetic pedigreeing); walk-back selection and marker assisted selection, using quantitative trait loci

description: We report the detection for the first time in space of three new pure hydrocarbon cycles in TMC-1: c-C3HCCH (ethynyl cyclopropenylidene), c-C5H6 (cyclopentadiene) and c-C9H8 (indene). We derive a column density of 3.1e11 cm-2 for the former cycle and similar values, in the range (1-2)e13 cm-2, for the two latter molecules. This means that cyclopentadiene and indene, in spite of their large size, are exceptionally abundant, only a factor of five less abundant than the ubiquitous cyclic hydrocarbon c-C3H2. The high abundance found for these two hydrocarbon cycles, together with the high abundance previously found for the propargyl radical (CH2CCH) and other hydrocarbons like vinyl and allenyl acetylene (Agundez et al. 2021; Cernicharo et al. 2021a,b), start to allow us to quantify the abundant content of hydrocarbon rings in cold dark clouds and to identify the intermediate species that are probably behind the in situ bottom-up synthesis of aromatic cycles in these environments. While c-C3HCCH is most likely formed through the reaction between the radical CCH and c-C3H2, the high observed abundances of cyclopentadiene and indene are difficult to explain through currently proposed chemical mechanisms. Further studies are needed to identify how are five- and six-membered rings formed under the cold conditions of clouds like TMC-1.

description: This volume covers Leg 47, Part 2 of the cruises of the Drilling Vessel Glomar Challenger. On Leg 47B, the Glomar Challenger sailed from Vigo, Spain to Brest, France between April and May of 1976. Site 398 was drilled during Leg 47B of the Deep Sea Drilling Project 20 km south of Vigo Seamount which is on the southern end of the Galicia Banks on the western Iberian continental margin. Galicia Bank had the topographic appearance of a detached and isolated fragment of the Iberian Peninsula cut off from the mainland of Europe by a rather deep (-3000 m) trough. The location of Site 398 is within the axis of this trough approximately 160 km from the present-day coast of Portugal and immediately to the south of a major prominence known as Vigo Seamount. The JOIDES Passive Margin Advisory Panel considered the Galicia region as belonging to the continental margin province of the eastern North Atlantic. The attractiveness of the Galicia region for deep drilling in IPOD Phase I focused on the general absence of major offshore deltas (ancient and modern) along the western coast of Portugal, and hence, the likelihood of encountering a thinner blanket of Mesozoic and Cenozoic clastic sediments than exists on segments of the northwest African margin. From the earliest planning stage of IPOD Phase I, the location of Site 398 showed promise of permitting penetration with existing drilling technology into ancient marine sediments deposited on and transgressive across a continental edge during the rupture of southern Europe from North America.

description: For sufficiently strong magnetic fields and/or low temperatures, the neutron star surface may be in a condensed state with little gas or plasma above it. Such surface condensation can significantly affect the thermal emission from isolated neutron stars, and may lead to the formation of a charge-depleted acceleration zone ("vacuum gap") in the magnetosphere above the stellar polar cap. Using the latest results on the cohesive property of magnetic condensed matter, we quantitatively determine the conditions for surface condensation and vacuum gap formation in magnetic neutron stars. We find that condensation can occur if the thermal energy kT of the neutron star surface is less than about 8% of its cohesive energy Q_s, and that a vacuum gap can form if the neutron star's rotation axis and magnetic moment point in opposite directions and kT is less than about 4% of Q_s. Thus, vacuum gap accelerators may exist for some neutron stars. Motivated by this result, we also study the physics of pair cascades in the vacuum gap model for photon emission by accelerating electrons and positrons due to both curvature radiation and resonant/nonresonant inverse Compton scattering. Our calculations of the condition of cascade-induced vacuum breakdown and the related pulsar death line/boundary generalize previous works to the superstrong field regime. We find that inverse Compton scatterings do not produce a sufficient number of high energy photons in the gap and thus do not lead to pair cascades for most neutron star parameters. We discuss the implications of our results for the recent observations of neutron star thermal radiation as well as for the detection/non-detection of radio emission from high-B pulsars and magnetars.

description: No abstracts are to be cited without prior reference to the author.RAPD analysis was performed on 258 minke whales: 201 individuals from the North Atlantic (NA) and 57 from the Western North Pacific (WNP). Nine 10-mer primers generated 20 RAPD-markers. Of these, 2 were present only in individuals from the WNP and 1 was present only in individuals from the NA. Six other markers showed a 50% or higher difference in frequency between the two oceans. The •• matrix of absence/presence of the markers was submitted to principal component analysis (PCA) and to analysis of the molecular variance (AMOVA). The first factor of the PCA separated clearly the minke whales from the NA from those of the WNP. However, minke whales captured in different small areas of the NA (Northeastern: EN, North Sea; EC, Lofoten-Vesterfilen; EB; Finnmark and Barents Sea; ES, Bear Island and Spitsbergen; and Central: CM, Jan Mayen), or in_ the WNP (7, 8, 11) did not form separate clusters. AMOVA of the data allocated over 63% (p<0.00001) of the total genetic variability of the model to differences between the NA and the WNP, and over 36% to within ocean individual differences. 2.6% (p<0.005) and 2.42% (p

description: For reliable and efficient communications of aerial platforms, such as unmanned aerial vehicles (UAVs), the cellular network is envisioned to provide connectivity for the aerial and ground user equipment (GUE) simultaneously, which brings challenges to the existing pattern of the base station (BS) tailored for ground-level services. Thus, we focus on the coverage probability analysis to investigate the coexistence of aerial and terrestrial users, by employing realistic antenna and channel models reported in the 3rd Generation Partnership Project (3GPP). The homogeneous Poisson point process (PPP) is used to describe the BS distribution, and the BS antenna is adjustable in the down-tilted angle and the number of the antenna array. Meantime, omnidirectional antennas are used for cellular users. We first derive the approximation of coverage probability and then conduct numerous simulations to evaluate the impacts of antenna numbers, down-tilted angles, carrier frequencies, and user heights. One of the essential findings indicates that the coverage probabilities of high-altitude users become less sensitive to the down-tilted angle. Moreover, we found that the aerial user equipment (AUE) in a certain range of heights can achieve the same or better coverage probability than that of GUE, which provides an insight into the effective deployment of cellular-connected aerial communications.

Stable equivariant abelianization, its properties, and applications

description: Let $G$ be a finite group. For a based $G$-space $X$ and a Mackey functor $M$, a topological Mackey functor $X\widetilde\otimes M$ is constructed, which will be called the stable equivariant abelianization of $X$ with coefficients in $M$. When $X$ is a based $G$-CW complex, $X\widetilde\otimes M$ is shown to be an infinite loop space in the sense of $\mathcal{G}$-spaces. This gives a version of the $RO(G)$-graded equivariant Dold-Thom theorem. Applying a variant of Elmendorf's construction, we get a model for the Eilenberg-Mac Lane spectrum $HM$. The proof uses a structure theorem for Mackey functors and our previous results.
title: The standardization of biodiversity: how politicization changes standardization for corporate sustainability reporting
Creators: name: Zenglein, Florian
Publisher: name: Frontiers Media S.A.
Year: 2025

description: This article asks how politicization changes the standardization of biodiversity in the realm of corporate sustainable reporting (CSR) frameworks. The study encompasses three areas: First, the participatory processes in standardization; second, the substantive prioritization of conservation considerations over economic aspects within standards; and third, the interplay between private and public standard-setting bodies. It argues that the European Union (EU) is taking on a more assertive role, shaping corporate reporting practices and the standards established by private organizations. Additionally, the standard-setting process is evolving from a technical exercise to a more politicized undertaking. The introduction of the EU Green Deal (EUG) brought in new biodiversity regulations, CSR frameworks, and standards, resulting in a new dynamic in politicizing biodiversity standardization. As a result, the number of actors with opposing interests is increasing, thereby intensifying the contestation of the standardization of biodiversity. Therefore, political rather than technical considerations increasingly drive biodiversity standardization processes in the EU. The EU is progressively expanding its role in two distinct yet complementary ways. Firstly, it is implementing political objectives through targeted reporting. Secondly, it provides an arena in which various actors are included. To elaborate on this argument, a qualitative analysis in the European context is conducted, highlighting the dynamics in the development of standards in CSR frameworks. Accordingly, the analysis encompasses standards and frameworks proposed by the EU, as well as by private standard-setting bodies GRI, ISO, ISBB, and CDP.
