description: Based on the superconducting quantum interference device (SQUID) equations described by the resistively- and capacitively-shunted junction model coupled to the equation of motion of a damped harmonic oscillator, we provide simulations to quantitatively describe the interaction between a dc SQUID and an integrated doubly clamped cantilever. We have chosen to investigate an existing experimental configuration and have explored the motion of the cantilever and the reaction of the SQUID as a function of the voltage-flux $V(Φ)$ characteristics. We clearly observe the Lorentz force back-action interaction and demonstrate how a sharp transition state drives the system into a nonlinear-like regime, and modulates the cantilever displacement amplitude, simply by tuning the SQUID parameters.

description: We present optical and ultraviolet observations of nearby type Ic supernova SN 2017ein as well as detailed analysis of its progenitor properties from both the early-time observations and the prediscovery Hubble Space Telescope (HST) images. The optical light curves started from within one day to $\sim$275 days after explosion, and optical spectra range from $\sim$2 days to $\sim$90 days after explosion. Compared to other normal SNe Ic like SN 2007gr and SN 2013ge, \mbox{SN 2017ein} seems to have more prominent C{\footnotesize II} absorption and higher expansion velocities in early phases, suggestive of relatively lower ejecta mass. The earliest photometry obtained for \mbox{SN 2017ein} show indications of shock cooling. The best-fit obtained by including a shock cooling component gives an estimate of the envelope mass as $\sim$0.02 M$_{\odot}$ and stellar radius as 8$\pm$4 R$_{\odot}$. Examining the pre-explosion images taken with the HST WFPC2, we find that the SN position coincides with a luminous and blue point-like source, with an extinction-corrected absolute magnitude of M$_V$$\sim$$-$8.2 mag and M$_I$$\sim$$-$7.7 mag.Comparisons of the observations to the theoretical models indicate that the counterpart source was either a single WR star or a binary with whose members had high initial masses, or a young compact star cluster. To further distinguish between different scenarios requires revisiting the site of the progenitor with HST after the SN fades away.

description: The dynamics of spatiotemporal patterns in oscillatory reaction-diffusion systems subject to periodic forcing with a spatially random forcing amplitude field are investigated. Quenched disorder is studied using the resonantly forced complex Ginzburg-Landau equation in the 3:1 resonance regime. Front roughening and spontaneous nucleation of target patterns are observed and characterized. Time dependent spatially varying forcing fields are studied in the 3:1 forced FitzHugh-Nagumo system. The periodic variation of the spatially random forcing amplitude breaks the symmetry among the three quasi-homogeneous states of the system, making the three types of fronts separating phases inequivalent. The resulting inequality in the front velocities leads to the formation of ``compound fronts'' with velocities lying between those of the individual component fronts, and ``pulses'' which are analogous structures arising from the combination of three fronts. Spiral wave dynamics is studied in systems with compound fronts.

description: The infrared (IR) emission of polycyclic aromatic hydrocarbons (PAHs) permeates our universe; astronomers have detected the IR signatures of PAHs around many interstellar objects. The IR emission of interstellar PAHs differs from their emission as seen under conditions on Earth, as they emit through a collisionless cascade down through their excited vibrational states from high internal energies. The difficulty in reproducing interstellar conditions in the laboratory results in a reliance on theoretical techniques. However, the size and complexity of PAHs requires careful consideration when producing the theoretical spectra. In this work we outline the theoretical methods necessary to lead to a fully theoretical IR cascade spectra of PAHs including: an anharmonic second order vibrational perturbation theory (VPT2) treatment; the inclusion of Fermi resonances through polyads; and the calculation of anharmonic temperature band shifts and broadenings (including resonances) through a Wang--Landau approach. We also suggest a simplified scheme to calculate vibrational emission spectra that retains the essential characteristics of the full IR cascade treatment and can directly transform low temperature absorption spectra in IR cascade spectra. Additionally we show that past astronomical models were in error in assuming a 15 cm$^{-1}$ correction was needed to account for anharmonic emission effects.

description: The aim of this paper is to analyse the current situation and potential for the development of organic agriculture in Serbia. Despite the favourable agri-ecological conditions for the development of organic agriculture, this branch of agriculture in Serbia significantly lags behind the world and European average in terms of the percentage of agricultural land under organic production. The motive for the conducted analysis within this paper stems from the fact that the demand for organic products in the EU has been increasing at a rate of about 10% annually in recent years, which represents a chance for Serbian agriculture. Data sources used are from the Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia (MAFWM), Statistical Office of the Republic of Serbia (SORS) and Research Institute of Organic Agriculture (FIBL) while the basic research method is interview ith experts and participants in organic agriculture. The results of the analysis show that the main limiting factors for the development of Serbian organic agriculture are dominance of small and economically weak producers and insufficient consumer confidence in organic products. The path to the development of organic agriculture is in the increased cooperatives activity and the improvement of consumer confidence in organic products.

description: Multi-wavelength campaigns have been carried out to study the correlation between the very high energy (VHE) $γ$-ray and the X-ray emissions in blazars but, no conclusive results have been achieved yet. In this paper, we add Milagro data to the existing VHE $γ$-ray data from HEGRA-CT1 and Whipple and test the consistency and robustness of the reported correlation between VHE $γ$-ray and X-ray fluxes in Mrk 421. We found that at monthly time scale the correlation is robust, consistent between instruments and described as a linear function. Furthermore, most of the fluxes on shorter time scales are consistent with the correlation within 3 $σ_A$ even, where $σ_A$ is an estimated intrinsic scatter. However, a break-down of the correlation becomes clearly evident at high states of activity with fluxes $\rm \gtrsim 2.5\times 10^{-10}\, cm^{-2}s^{-1}$ at energies above 400 GeV independently of the time scale, observational period or instrument, even for single flares, the X-ray and VHE $γ$-ray emissions lie on the correlation until the VHE $γ$-ray flux reaches values higher than the one mentioned above. We have interpreted our results within the one-zone synchrotron self-Compton model. We found that describing a single and unique $γ$-ray/X-ray correlation strongly narrows the range of possible values of the magnetic field $B$ when a constant value of the spectral index along the correlation is assumed.

We suposse that dark matter is a scalar field endowed with a scalar potential. We obtain that a) the effective energy density goes like $1/(r^2+r_{c}^{2})$ and b) the resulting circular velocity profile of tests particles is in good agreement with the observed one.

Operators for quantized directions

Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Inspired by the spin geometry theorem, two operators are defined which measure angles in the quantum theory of geometry. One operator assigns a discrete angle to every pair of surfaces passing through a single vertex of a spin network. This operator, which is effectively the cosine of an angle, is defined via a scalar product density operator and the area operator. The second operator assigns an angle to two ``bundles'' of edges incident to a single vertex. While somewhat more complicated than the earlier geometric operators, there are a number of properties that are investigated including the full spectrum of several operators and, using results of the spin geometry theorem, conditions to ensure that semiclassical geometry states replicate classical angles.

description: Within the framework of the Lee model, we analyze in detail the difference between the energy derivative of the phase shift and the standard spectral function of the unstable state. The fact that the model is exactly solvable allows us to demonstrate the construction of these observables from various exact Green functions. The connection to a formula due to Krein, Friedal, and Lloyd is also examined. We also directly demonstrate how the derivative of the phase shift correctly identifies the relevant interaction contributions for consistently including an unstable state in describing the thermodynamics.

A semidiscrete finite element approximation of a time-fractional Fokker-Planck equation with nonsmooth initial data

description: We present a new stability and convergence analysis for the spatial discretization of a time-fractional Fokker--Planck equation in a convex polyhedral domain, using continuous, piecewise-linear, finite elements. The forcing may depend on time as well as on the spatial variables, and the initial data may have low regularity. Our analysis uses a novel sequence of energy arguments in combination with a generalized Gronwall inequality. Although this theory covers only the spatial discretization, we present numerical experiments with a fully discrete scheme employing a very small time step, and observe results consistent with the predicted convergence behavior.
Natural Attack for Pre-trained Models of Code

description: Pre-trained models of code have achieved success in many important software engineering tasks. However, these powerful models are vulnerable to adversarial attacks that slightly perturb model inputs to make a victim model produce wrong outputs. Current works mainly attack models of code with examples that preserve operational program semantics but ignore a fundamental requirement for adversarial example generation: perturbations should be natural to human judges, which we refer to as naturalness requirement. In this paper, we propose ALERT (nAturaLnEss AwaRe ATtack), a black-box attack that adversarially transforms inputs to make victim models produce wrong outputs. Different from prior works, this paper considers the natural semantic of generated examples at the same time as preserving the operational semantic of original inputs. Our user study demonstrates that human developers consistently consider that adversarial examples generated by ALERT are more natural than those generated by the state-of-the-art work by Zhang et al. that ignores the naturalness requirement. On attacking CodeBERT, our approach can achieve attack success rates of 53.62%, 27.79%, and 35.78% across three downstream tasks: vulnerability prediction, clone detection and code authorship attribution. On GraphCodeBERT, our approach can achieve average success rates of 76.95%, 7.96% and 61.47% on the three tasks. The above outperforms the baseline by 14.07% and 18.56% on the two pre-trained models on average. Finally, we investigated the value of the generated adversarial examples to harden victim models through an adversarial fine-tuning procedure and demonstrated the accuracy of CodeBERT and GraphCodeBERT against ALERT-generated adversarial examples increased by 87.59% and 92.32%, respectively.

The performed measurements cover a wide parameter range of driving frequencies and sample viscosities. In the capillary wave regime the bifurcation diagrams exhibit a frequency independent scaling proportional to the wavelength. We also provide numerical simulations of the full Navier-Stokes equations, which are in quantitative agreement up to supercritical drive amplitudes of 20%. The validity of an existing perturbation analysis is found to be limited to 2.5% overcriticaly.

description: For an arbitrary Tolman wormhole, unconstrained by symmetry, we shall define the bounce in terms of a three-dimensional edgeless achronal spacelike hypersurface of minimal volume. (Zero trace for the extrinsic curvature plus a "flare-out" condition.) This enables us to severely constrain the geometry of spacetime at and near the bounce and to derive general theorems regarding violations of the energy conditions--theorems that do not involve geodesic averaging but nevertheless apply to situations much more general than the highly symmetric FRW-based subclass of Tolman wormholes. [For example: even under the mildest of hypotheses, the strong energy condition (SEC) must be violated.] Alternatively, one can dispense with the minimal volume condition and define a generic bounce entirely in terms of the motion of test particles (future-pointing timelike geodesics), by looking at the expansion of their timelike geodesic congruences. One re-confirms that the SEC must be violated at or near the bounce. In contrast, it is easy to arrange for all the other standard energy conditions to be satisfied.

description: Spin networks, essentially labeled graphs, are ``good quantum numbers'' for the quantum theory of geometry. These structures encompass a diverse range of techniques which may be used in the quantum mechanics of finite dimensional systems, gauge theory, and knot theory. Though accessible to undergraduates, spin network techniques are buried in more complicated formulations. In this paper a diagrammatic method, simple but rich, is introduced through an association of 2 by 2 matrices to diagrams. This spin network diagrammatic method offers new perspectives on the quantum mechanics of angular momentum, group theory, knot theory, and even quantum geometry. Examples in each of these areas are discussed.

External Energy Paradigm For Black Holes

Publisher: name: arXiv
Year: 2018

description: A new paradigm for black holes is introduced. It is known as the External Energy Paradigm. The paradigm asserts that all energies of a black hole are external quantities; they are absent inside the horizon. These energies include constituent mass, gravitational energy, electrostatic energy, rotational energy, heat energy, etc. As a result, quantum particles with charges and spins cannot exist inside the black hole. To validate the conclusion, we derive the moment of inertia of a Schwarzschild black hole and find that it is exactly equal to $mass \times (Schwarzschild \,\,\, radius)^{2}$, indicating that all mass of the black hole is located at the horizon. This remarkable result can resolve several long-standing paradoxes in black hole theory; such as why entropy is proportional to area and not to volume, the singularity problem, the information loss problem, and the perplexing firewall controversy.

description: Random Dirac fermions in a two-dimensional space are studied numerically. We realize them on a square lattice using the $π$-flux model with random hopping. The system preserves two symmetries, the time-reversal symmetry and the symmetry denoted by ${{\cal H},γ}=0$ with a $4\times 4$ matrix $γ$ in an effective field theory. Although it belongs to the orthogonal ensemble, the zero-energy states do not localize and become critical. The density of states vanishes at zero energy as $\sim E^α$ and the exponent $α$ changes with strength of the randomness, which implies the existence of the critical line. Rapid growth of the localization length near zero energy is suggested and the eigenstates near zero energy exhibit anomalous behaviour which can be interpreted as a critical slowing down in the available finite-size system. The level-spacing distributions close to zero energy deviate from both the Wigner surmise and the Poissonian, and exhibit critical behaviour which reflects the existence of critical states at zero energy.

description: Misfit strain is inevitable in various heterostructures like the graphene/MoS 2 van der Waals heterostructure. Although the misfit strain effect on electronic and other physical properties have been well studied, it is still unclear how will the misfit strain affect the performance of the nanomechanical resonator based on the graphene/MoS 2 heterostructure. By performing molecular dynamics simulations, we disclose a misfit strain-induced decoupling phenomenon between the graphene layer and the MoS 2 layer during the resonant oscillation of the heterostructure. A direct relationship between the misfit strain and the decoupling mechanism is successfully established through the retraction force analysis. We further suggest to use the graphene/MoS 2 /graphene sandwich heterostructure for the nanomechanical resonator application, which is able to prevent the misfit strain-related decoupling phenomenon. These results provide valuable information for the future application of the graphene/MoS 2 heterostructure in the nanomechanical resonator field.

description: As a production system, organic agriculture is linked to less intensive practices. Therefore, its main mission is to produce much more ecological products and services than conventional agriculture. It does not use potentially harmful technologies technological approaches and inputs of intensive agriculture, as are pesticides, synthetic nitrogen fertilizers, GMO crops or veterinary and anthelmintic antibiotics, thus reducing environmental and health risks. Consumption of organic products has been increased in last couple decades in Romania. The main paper goal is to analyse the consumers’ attitudes toward the organic products, primarily agri-food products, as well as their buying motives and satisfaction with the existing offer in the national market. Used methodological framework contains an online survey conducted in the first half of 2020. Among achieved results next has been underlined that majority of respondents consume organic products so often. Their first choice is organic vegetable products, followed by organic animal products and in some cases organic cosmetics.

description: We have studied the quantum and classical solutions of a particle constrained to move inside a sector circular billiard with angle $θ_w$ and its pacman complement with angle $2π-θ_w$. In these billiards rotational invariance is broken and angular momentum is no longer a conserved quantum number. The "fractional" angular momentum quantum solutions are given in terms of Bessel functions of fractional order, with indices $λ_p={pπ\over {θ_w}}$, $p=1,2,...$ for the sector and $μ_q={qπ\over {2π- θ_w}}$, $q=1,2...$ for the pacman. We derive a ``duality'' relation between both fractional indices given by $λ_p={{pμ_q} \over {2μ_q - q}}$ and $μ_q = {{qλ_p} \over {2λ_p - p}}$. We find that the average of the angular momentum $\hat L_z$ is zero but the average of $\hat L^2_z$ has as eigenvalues $λ_p^2$ and $μ_q^2$. We also make a connection of some classical solutions to their quantum wave eigenfunction counterparts.

Deliverable 4.1

EXECUTIVE SUMMARY

The document comprehensively reviews the clinical applications and future potential of alpha-emitting radionuclides in cancer treatment. It highlights the advantages of alpha particles in targeting cancer cells with minimal radiation to normal tissue, emphasising the need for high specificity and stability in delivery mechanisms.

The approval of radium-223 (223Ra) therapy in 2013 marked a significant advancement in alpha-emitting therapeutic radiopharmaceuticals, primarily used in prostate cancer treatment. However, the document suggests that the full clinical potential of alpha particle therapy remains unexplored.

The SECURE project is introduced as a major initiative aimed at enhancing the sustainability and safety of medical isotope production in Europe. It focuses on the development of irradiation targets and production routes for both existing and new isotopes, particularly alpha emitters and beta-emitting theragnostic radionuclides. The project's ambition is to optimize the use of current resources to create new opportunitiesin healthcare and economics.

The document also outlines the methodology for a literature review conducted on selected radionuclides, including actinium-225 (225Ac), bismuth-213 (213Bi), astatine-211 (211At), lead-212 (212Pb), terbium-149 (149Tb), radium-223 (223Ra), and thorium-227 (227Th). These were chosen based on their clinical significance as identified in the PRISMAP report and further literature searches. The review process involved searching major databases using specific keywords related to alpha-emitter therapy and was limited to articles in English. In particular, for each selected radionuclide the physical characteristics, the radiochemistry, and the pre-clinical and clinical study are explored. 

In conclusion, the document serves as a literature review of current and potential clinical applications of new alpha-emitting radionuclides, sharing insights from the SECURE consortium's experiences and providing recommendations for future clinical trials to establish the therapeutic efficacy of these radionuclides

description: In this report, we examine the landscape of food retailers across the contiguous United States, with a focus on rural America and grocery stores. Changes in food retailers have raised concerns about food access and have led Federal policymakers to introduce several pieces of legislation to improve access to healthy foods, such as the Healthy Food Financing Initiative. We use the National Establishment Time Series (NETS) dataset to create a more complete picture of food retailers, while using store-level information to examine sales and employment, and to distinguish between national, regional, and local chains and single location stores. We find that in rural and urban nonmetro counties, grocery stores outnumbered other forms of food retailers, but that grocery stores declined from 1990 to 2015 while dollar stores and supercenters increased steadily. We also found that although single location grocery stores outnumbered chains in 2015, they have been decreasing throughout this period, resulting in single location grocery stores as a share of food retailers decreasing from 87 to 82 percent.

In the process, we relate, on-shell, the usual superpotential basis for classifying pseudo-tensors with one spanned by polynomials in the curvature.

description: IUCAA Digital Sampling Array Controller (IDSAC) is a flexible and generic yet powerful CCD controller which can handle a wide range of scientific detectors. Based on an easily scalable modular backplane architecture consisting of Single Board Controllers (SBC), IDSAC can control large detector arrays and mosaics. Each of the SBCs offers the full functionality required to control a CCD independently. The SBCs can be cold swapped without the need to reconfigure them. Each SBC can handle data from up to four video channels with or without dummy outputs at speeds up to 500 kilo Pixels Per Second (kPPS) Per Channel with a resolution of 16 bits. Communication with Linux based host computer is through a USB3.0 interface, with the option of using copper or optical fibers. A Field Programmable Gate Array (FPGA) is used as the master controller in each SBC which allows great flexibility in optimizing performance by adjusting gain, timing signals, bias levels, etc. using user-editable configuration files without altering the circuit topology. Elimination of thermal kTC noise is achieved via Digital Correlated Double Sampling (DCDS). We present the results of noise performance characterization of IDSAC through simulation, theoretical modeling, and actual measurements. The contribution of different types of noise sources is modeled using a tool to predict noise of a generic DCDS signal chain analytically. The analytical model predicts the net input referenced noise of the signal chain to be 5 electrons for 200k pixels per second per channel readout rate with 3 samples per pixel. Using a cryogenic test set up in the lab, the noise is measured to be 5.4 e (24.3 \muV), for the same readout configuration.
