description: Ultrafast phase transitions induced by femtosecond light pulses present a new opportunity for manipulating the properties of materials. Understanding how these transient states are different from, or similar to, their thermal counterparts is key to determining how materials can exhibit properties that are not found in equilibrium. In this paper, we reexamine the case of the light-induced insulator-metal phase transition in the prototypical, strongly correlated material VO$_2$, for which a nonthermal Mott-Hubbard transition has been claimed. Here, we show that heat, even on the ultrafast timescale, plays a key role in the phase transition. When heating is properly accounted for, we find a single phase-transition threshold corresponding to the thermodynamic structural insulator-metal phase transition, and we find no evidence of a hidden transient Mott-Hubbard nonthermal phase. The interplay between the initial thermal state and the ultrafast transition may have implications for other transient states of matter.

description: The antiviral potential of natural polysaccharide compounds has been demonstrated, especially against enveloped viruses and members of the Herpesviridae family. Two polysaccharide fractions obtained from Stevia rebaudiana (Bertoni) leaves, that were active against Herpes simplex virus type 1 (HSV-1) were studied to investigate their mode of action. Both polysaccharides - SFW (crude faction) and SSFK (homogeneous alkaline fraction) - exerted antiviral effects on the initial stages of HSV-1 infection by inhibiting viral adsorption and penetration. When added after virus internalization, both fractions decreased plaque size. The effect of the fractions was confirmed by investigating viral glycoprotein expression. Based on the mode of action of the polysaccharides demonstrated in the present work and on their selectivity index, the polysaccharides obtained from S. rebaudiana could be an alternative treatment of infections caused by HSV-1.

description: Rhaponticum acaule (L.) DC. is a medicinal plant commonly used for the treatment of some illnesses such as gastrointestinal infections. In this work, we report the composition of different parts of this plant on phenolic compounds, their quantification, and antioxidant activity. The obtained results reported that methanolic extracts of the three parts studied revealed high phenolic contents. For flavonoid contents, the highest contents were reported in organic extracts of leaf part. In addition, results obtained from the study of the antioxidant activity showed that methanolic extract of root presented the highest activity, in DPPH• scavenging ability test with an IC50 of 0.31 ± 0.04 mg/mL and in FRAP test with an EC50 of 1.06 ± 0.02 mg/mL. The RP-HPLC-PDA analysis revealed the presence of five phenolic acids (sinapic, caffeic, chlorogenic, ferulic and syringic acids), one flavanone (naringenin), one flavonol (rutin) and vanillin.

description: High-purity germanium (HPGe) detectors are widely used for the measurement of the low concentrated radioactivities. For the Super-Kamiokande-Gadolinium project, the concentration of radium in Gd$_2$(SO$_4$)$_3{\cdot}$8H$_2$O is determined by using HPGe detectors. The amount of the sample is generally limited by the size of the sample space of a HPGe detector. This leads the limitation of the detector efficiency. A new method of chemical extraction using the molecular recognition resin was developed to minimize this problem. Using the developed method, radium could be extracted from Gd$_2$(SO$_4$)$_3{\cdot}$8H$_2$O and concentrated to smaller amount of the resin at a recovery rate of 81$\pm$4\%, which was estimated by using barium as a recovery monitor. This made it possible to set the sample closer to an HPGe crystal and reduce self screening effect, resulting in increasing the detection efficiency of an HPGe detector. The developed method is reported on this letter.

description: This White Paper addresses this imbalance by proposing a paradigm shift - a new approach to valuing natural capital and to enabling its incorporation in the economic system. This document is a synthesis of a longer background report under preparation by the Nature- Based Economy Working Group of Task Force III of the European Commission. The recommendations of this document will be debated at a high level policy dialogue at the end of June 20211 following which they will be shared as part of an open consultation process running until mid September 2021. The outcome of this process will form the basis for an EC Expert Publication on the Nature-based Economy to be launched at the European Business Summit in November 2021. The recommendations of this White Paper provide a basis for dialogue with policy makers, at all levels of government and across all fields of policy implementation, and with wider stakeholders in business, society and the innovation ecosystem on the changes needed to shift towards a Nature-based Economy. It particularly aims at stimulating valuable cross-sectoral policy discussions between policy makers responsible for climate change and biodiversity policy and those responsible for sustainable economic growth policies within the context of rapidly depleting stocks of natural capital.

description: Toxicity of the pesticide carbofuran (CF) can be alleviated by curcumin, if not for its poor bioavailability. Hence, we investigated the effect of a bioavailable curcumin-galactomannan complex (CGM) on CF-induced neurotoxicity in rats in comparison to that of unformulated standard curcumin (CS). The CF (5 mg/kg b.wt/day) treatment for 90 days produced chronicity model which were treated with either CS or CGM (100 mg/kg b.wt and 250 mg/kg b.wt/day) for another 30 days. Improvement in CF-induced behaviour was evident in endurance, motor co-ordination and pain response on both CS (p

description: Evaluating the propagator by the usual time-sliced manner, we use it to compute the second virial coefficient of an anyon gas interacting through the repulsive potential of the form $g/r^2 (g > 0)$. All the cusps for the unpolarized spin-1/2 as well as spinless cases disappear in the $ω\to 0$ limit, where $ω$ is a frequency of harmonic oscillator which is introduced as a regularization method. As $g$ approaches to zero, the result reduces to the noninteracting hard-core limit.

Kondo Insulators Modeled by the One Dimensional Anderson Lattice: A Numerical Renormalization Group Study

Year: 1995
Subjects: subject: Condensed Matter (cond-mat)

description: In order to better understand Kondo insulators, we have studied both the symmetric and asymmetric Anderson lattices at half-filling in one dimension using the density matrix formulation of the numerical renormalization group. We have calculated the charge gap, spin gap and quasiparticle gap as a function of the repulsive interaction U using open boundary conditions for lattices as large as 24 sites. We find that the charge gap is larger than the spin gap for all U for both the symmetric and asymmetric cases. RKKY interactions are evident in the f-spin-f-spin correlation functions at large U in the symmetric case, but are suppressed in the asymmetric case as the f-level approaches the Fermi energy. This suppression can also be seen in the staggered susceptibility and it is consistent with neutron scattering measurements in CeNiSn.

Nuclear energy policy in the united states 1990-2010: A federal or state responsibility?
Creators: name: Heffron, Raphael J.
Publisher: name: Faculty of Economics
Year: 2013
Subjects: Nuclear energy, policy inaction, project management, public administration

description: This paper examines from a policy perspective nuclear energy policy in the United States (US) from 1990 to 2010 and questions whether it is or has become a Federal or State responsibility. The present study, as befits policy research, engages with many disciplines (for example, in particular, law and politics) and hence the contributions move beyond that of nuclear energy policy literature and in particular to that on nuclear new build and other assessments of large infrastructure projects. Several examples at the Federal level are identified that demonstrate that the nuclear industry has evolved to a stage where it requires a focus on the power of actions at a more localised (state) level in order to re-ignite the industry. The research concludes that there remains a misunderstanding of the issue of project management for complex construction projects, and it is highly arguable whether many of its issues have been resolved. Further, the research asserts that the economics of nuclear energy are not the most nfluential reason for no nuclear new build in the US.

description: We prove new bounds on the control cost for the abstract heat equation, assuming a spectral inequality or uncertainty relation for spectral projectors. In particular, we specify quantitatively how upper bounds on the control cost depend on the constants in the spectral inequality. This is then applied to the heat flow on bounded and unbounded domains modeled by a Schrödinger semigroup. This means that the heat evolution generator is allowed to contain a potential term. The observability/control set is assumed to obey an equidistribution or a thickness condition, depending on the context. Complementary lower bounds and examples show that our control cost estimates are sharp in certain asymptotic regimes. One of these is dubbed homogenization regime and corresponds to the situation that the control set becomes more and more evenly distributed throughout the domain while its density remains constant.

High Rate Neutrino Detectors for Neutrino Factories

Publisher: name: arXiv
Year: 2000
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: Three types of high rate neutrino detectors for neutrino interaction physics at neutrino factories are discussed. High performance general-purpose detectors might collect event samples on the order of a billion events or more. This could greatly improve on existing analyses of neutrino interactions and also lead to new and important analysis topics including, for example, precise determinations of the CKM matrix elements |Vub| and |Vcb|. The potential of such general purpose detectors is illustrated with reference to a detector, presented previously in reference hep-ex/9907033, that is structured around a novel and compact vertexing and tracking neutrino target comprising a stack of CCD pixel devices. Design ideas and prospects are also discussed for two types of specialized detectors: (i) polarized targets filled with polarized solid protium-deuterium (HD), for unique and powerful studies of the nucleon's spin structure, and (ii) Fully active liquid tracking targets with masses of several tonnes for precise determinations of the weak mixing angle, from the total cross-section for neutrino-electron scattering. All three detector types pose severe technical challenges but their utilization could add significantly to the physics motivation for neutrino factories.

description: A non-equilibrium statistical-thermodynamic approach to the study of a Fröhlich-Bose-Einstein condensation of magnons under radio-frequency radiation pumping is presented. Such a system displays a complex behavior consisting in steady-state conditions to the emergence of a synergetic dissipative structure resembling the Bose-Einstein condensation of systems in equilibium. A kind of "two fluid model" arises: the "normal" non-equilibrium structure and Fröhlich condensate or "non-equilibrium" one, which is shown to be an attractor to the system. We analyze some aspects of the irreversible thermodynamics of this dissipative complex system, namely, its informational entropy, expressions for the fluctuations in non-equilibrium conditions, the associated Maxwell relations and the formulation of a generalized $\mathscr{H}$-theorem. We also study the informational entropy production of the system, an order parameter is introduced and Glansdorff-Prigogine criteria for evolution and (in)stability are verified.

description: We theoretically investigate the interaction between the conductive graphene layer with the dual-spectral electromagnetically induced transparency (EIT) metamaterial and achieve independent amplitude modulation of the transmission peaks in terahertz (THz) regime. The dual-spectral EIT resonance results from the strong near field coupling effects between the bright cut wire resonator (CWR) in the middle and two dark double-split ring resonators (DSRRs) on the two sides. By integrating monolayer graphene under the dark mode resonators, the two transmission peaks of the EIT resonance can exhibit independent amplitude modulation via shifting the Fermi level of the corresponding graphene layer. The physical mechanism of the modulation can be attributed to the variation of damping factors of the dark mode resonators arising from the tunable conductivity of graphene. This work shows great prospects in designing multiple-spectral THz functional devices with highly flexible tunability and implies promising applications in multi-channel selective switching, modulation and slow light.
Ring Signatures: Logarithmic Size, No Setup -- from Standard Assumptions
Creators: name: Backes, Michael

name: Kluczniak, Kamil
Publisher: name: CISPA
Year: 2024

description: Ring signatures allow for creating signatures on behalf of an ad hoc group of signers,
hiding the true identity of the signer among the group. A natural goal is to
construct a ring signature scheme for which the signature size is short in the
number of ring members. Moreover, such a construction should not rely on a trusted setup and be proven secure under falsifiable standard assumptions. Despite many years of research this question is still open.

In this paper, we present the first construction of logarithmic-size ring signatures which do not rely on a trusted setup or the random oracle heuristic. Specifically, our scheme can be instantiated from standard assumptions and
the size of signatures grows only logarithmically in the number of ring members.

We also extend our techniques to the setting of linkable ring signatures, where signatures created using the same signing key can be linked.

description: It has been recently suggested by Arkani-Hamed, Dimopoulos and Dvali that gravity may become strong at energies not far above the electroweak scale and thus remove the hierarchy problem. Such a scenario can be tested at both present and future accelerators since towers of Kaluza-Klein gravitons and associated scalar fields now play an important phenomenological role. In this paper we examine several processes for their sensitivity to a low scale for quantum gravity including deep inelastic $ep$ scattering at HERA, high precision low energy $νN$ scattering, Bhabha and Moller scattering at linear colliders and both fermion and gluon pair production at $γγ$ colliders.

description: Four years after the gas supply crisis of January 2009, this paper looks at the market and policy changes that have changed the European gas situation, and their implications in terms of security of supply. Several positive developments are identified, including the byapssing of Ukraine by Gazprom-sponsored pipelines; the acceleration of import diversification in large markets of western Europe; the process of ‘commoditisation’ of natural gas in north-west Europe. The lack of meaningful progress in market integration between western and eastern-central Europe, however, leaves in place one of the main factors that made the 2009 crisis possible and conferred it its political significance. Overall, the European gas security situation has evolved in a positive direction mainly because of external forces, not EU policies.

description: Detecting faces and heads appearing in video feeds are challenging tasks in real-world video surveillance applications due to variations in appearance, occlusions and complex backgrounds. Recently, several CNN architectures have been proposed to increase the accuracy of detectors, although their computational complexity can be an issue, especially for real-time applications, where faces and heads must be detected live using high-resolution cameras. This paper compares the accuracy and complexity of state-of-the-art CNN architectures that are suitable for face and head detection. Single pass and region-based architectures are reviewed and compared empirically to baseline techniques according to accuracy and to time and memory complexity on images from several challenging datasets. The viability of these architectures is analyzed with real-time video surveillance applications in mind. Results suggest that, although CNN architectures can achieve a very high level of accuracy compared to traditional detectors, their computational cost can represent a limitation for many practical real-time applications.

description: The realization and study of arrays of interacting magnetic nanoislands, such as artificial spin ices, have reached mature levels of control that allow design and demonstration of exotic, collective behaviors not seen in natural materials. Advances in the direct manipulation of their local, binary moments also suggest a use as nanopatterned, interacting memory media, for computation {\it within} a magnetic memory. Recent experimental work has demonstrated the possibility of building logic gates from clusters of interacting magnetic domains, and yet the possibility of large scale integration of such gates can prove problematic even at the theoretical level. Here we introduce theoretically complete sets of logical gates, in principle realizable in an experiment, and we study the feasibility of their integration into tree-like circuits. By evaluating the fidelity control parameter between their collective behavior and their expected logic functionality we determine conditions for integration. Also, we test our numerical results against the presence of disorder in the couplings, showing that the design gate structure is robust to small coupling perturbations, and thus possibly to small imperfections in the fabrication of the islands.

Supersymmetry Breaking through Boundary Conditions Associated with the $U(1)_{R}$
Creators: name: Takenaga, Kazunori
Publisher: name: arXiv
Year: 1997
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The effects of boundary conditions of the fields for the compactified space directions on the supersymmetric theories are discussed. The boundary conditions can be taken to be periodic up to the degrees of freedom of localized $U(1)_{R}$ transformations. The boundary condition breaks the supersymmery to yield universal soft supersymmetry breaking terms. The 4-dimensional supersymmetric QED with one flavour and the pure supersymmetric QCD are studied as toy models when one of the space coordinates is compactified on $S^1$.

Inequality Constraints and Euler Equation Based Solution Methods
Creators: name: Rendahl, Pontus
Publisher: name: Faculty of Economics
Year: 2013
Subjects: Inequality constraints; Envelope theorem; Time iteration

description: Solving dynamic models with inequality constraints poses a challenging problem for two major reasons: dynamic programming techniques are reliable but often slow, while Euler equation based methods are fast but have problematic or unknown convergence properties. This paper attempts to bridge this gap. I show that a common iterative procedure on the Euler equation - usually referred to as time iteration - delivers a sequence of approximate policy functions that converges to the true solution under a wide range of circumstances. These circumstances extend to an arbitrarily large, but nite, set of endogenous and exogenous state-variables as well as a very broad spectrum of occasionally binding constraints.
Low energy atmospheric muon neutrinos in MACRO

description: We present the measurement of two event samples induced by atmospheric $ν_μ$ of average energy $ \bar {E}_ν\sim 4 GeV$. In the first sample, the neutrino interacts inside the MACRO detector producing an upward-going muon leaving the apparatus. The ratio of the number of observed to expected events is $ 0.57 \pm0.05_{stat} \pm0.06_{syst} \pm0.14_{theor}$ with an angular distribution similar to that expected from the Bartol atmospheric neutrino flux. The second is a mixed sample of internally produced downward-going muons and externally produced upward-going muons stopping inside the detector. These two subsamples are selected by topological criteria; the lack of timing information makes it impossible to distinguish stopping from downgoing muons. The ratio of the number of observed to expected events is $0.71 \pm 0.05_{stat} \pm0.07_{syst} \pm0.18_{theor}$ . Using the ratio of the two subsamples (for which most theoretical uncertainties cancel) we can test the pathlength dependence of the oscillation hypothesis. The probability of agreement with the no-oscillation hypothesis is 5% . The deviations of our observations from the expectations has a preferred interpretation in terms of $ν_μ$ oscillations with maximal mixing and $Δm^2 \sim 10^{-3} ÷10^{-2} eV^2$. These parameters are in agreement with our results from upward throughgoing muons, induced by $ν_μ$ of much higher energies.

Now Ailuroedus melanotis guttaticollis Stresemann, 1922. See Frith and Frith 2004: 237. In Mayr 1962a: 174 as Ailuroedus crassirostris guttaticollis, followed by Dickinson 2003: 427. Gilliard 1969: 266 pointed out why he considered A. melanotis and A. crassirostris to be separate species. HOLOTYPE: ZMB 49.295. Male. Loc.: Hunsteinspitze [Mt. Hunstein, middle reaches of the Sepik River, Papua New Guinea, 4°31' S, 142°40' E]. Date: 9 March 1913. Coll.: Bürgers No. 1436. Iris: reddish brown. Bill: greyish green. Feet: grey. [Skin; data on field and ZMB label]. PARATYPE: ZMB 2002.501 [new registration]. Male. Loc.: Hunsteinspitze, Sepik­range. Date: 26 February 1913. Coll.: Bürgers No. 1321. Iris: yellowish brown. Bill: whitish grey. Feet: grey. [Skin; data on field and ZMB label]. COMMENTS: Dr. Joseph Bürgers (1881–1954) participated as medical doctor and zoologist on the German Sepik­Expedition 1912–1913 (Gebhardt 1964: 56–57). A second male paratype, once at Berlin, was probably donated to the Zoological Museum Tring, and is now AMNH 679721 (Bürger's No. 1360, male, 1 March 1913, Huntsteinspitze). Most of Bürgers' specimens were not properly registered on arrival. It was only when Meise worked on the types of Berlin Museum that some of the types got formal registration. Frith and Frith (2004: 237) erred in citing the handwritten registration number of the holotype as ZMB 22.295 instead of ZMB 49.295.

title: Benefit Road: Short Stories
Creators: name: Stowe, Kathleen J.
Publisher: name: Old Dominion University
publisherIdentifier: https://ror.org/04zjtrb98
publisherIdentifierScheme: ROR
Year: 2012

description: Benefit Road is a work of realistic fiction composed of six short stories. Each protagonist is an individual in contemporary society, living an isolated existence, while struggling to connect with others and construct moral order out of chaos. A blind disabled child attended by his uncomplaining mother, geckos scrambling up a freshly painted wall to escape from a cat, a drowning boy, the revelry of a Fasching celebration, a toddler in a crib shrieking for his mother's attention, and an old dog on a wintry trail: A common thread linking these particular stories is the presence of an animal as a stand-in for absent or lacking human relationships. The predominant mood is one of resignation to the fact that life lived alone is a continuing struggle. Epiphanies highlight the recognition that connections and relationships present the only possibility of resolution.

description: The aim of this work is to apply the dynamical system approach to study the linear dynamics of the normal DGP brane-world model with agegraphic dark energy. The stability analysis of the model will be investigated and the phase plane portrait will be illustrated. The nature of critical points will be analyzed by evaluating the eigenvalues of a linearized Jacobi matrix. Also, the statefinder diagnostic procedure will be applied to show the slight deviation from the ΛCDM model. One of the most interesting results of this work is the great alleviation of the coincidence problem.
Efficiency and Environmental Factors in the US Electricity Transmission Industry
Creators: name: Llorca, Manuel

Publisher: name: Faculty of Economics
Year: 2013
Subjects: electricity transmission, heteroscedastic stochastic cost frontiers, inefficiency determinants

description: The electricity industry in most developed countries has been restructured over recent decades with the aim of improving both service quality and firms’ performance. Regulated segments (e.g. transmission) still provide the infrastructure for the competitive segments and represent a notable amount of the total price paid by final customers. However there is a lack of empirical studies that analyze firms’ performance in the electricity transmission sector. We conduct an empirical analysis of the US electricity transmission companies for the period 2001-2009. We use stochastic frontier models that allow us to identify determinants of firms’ inefficiency and to control for weather conditions, potentially one of the most decisive uncontrollable factors in electricity transportation. Our results suggest that there is room for improvement in the performance of the US electricity transmission system. Regulators should also take into account that more adverse conditions generate higher levels of inefficiency and that achieving long-term efficiency improvements tends to deteriorate firms’ short-term relative performance.

description: Hoplitis (Alcidamea) caularis (Morawitz, 1875)
 Distribution. Listed for Europe by Nieto et al. (2014). The species presumed occurrence in Europe was based on the erroneous synonymisation of Hoplitis (Alcidamea) turcestanica (Dalla Torre, 1896) with H. caularis by Warncke (1991) (Fateryga & Proshchalykin 2020). Confidently determined records of Hoplitis caularis are currently known only from Central Asia (M̧ller 2022).

Quark-Lepton Mass Matrices with $U(1)\times Z_2 \times Z_2'$ Flavor Symmetry
Creators: name: Tanimoto, Morimitsu
Publisher: name: arXiv
Year: 1999
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The U(1) flavor symmetry explains the large mixing of neutrinos while it leads to the unique texture for the quark mass matrices. It is remarked that U(1) symmetric mass matrices have the phenomenological defects. In the quark sector, the mixing $V_{ub}$ is predicted to be large compared with the expected value $ł^4$ at the GUT scale. In the lepton sector, U(1) charges, which give a large mixing in the neutrino sector, also lead to the large one in the charged lepton sector. In the viewpoint of the flavor symmetry, this is an unpleasant feature because the neutrino mass hierarchy is determined only by unknown coefficients of ${\cal O}(1)$, and the near-maximal flavor mixing is not guaranteed in the case of both large angle rotations. These defects disappear by introducing additional discrete symmetries $Z_2\times Z_2'$. The $U(1)\times Z_2\times Z_2'$ quark-lepton mass matrices are presented by taking account of the recent data of atmospheric neutrinos and solar neutrinos.

A System Dynamics Study of Uranium and the Nuclear Fuel Cycle
Creators: name: Rooney, Matthew

Subjects: System dynamics, uranium mining, nuclear fuel cycle, uranium market dynamics, sensitivity analysis

description: To advance current knowledge of the uranium market, a system dynamics model of the nuclear fuel cycle for the time period 1988 to 2048 has been developed. The proposed framework of analysis illustrates some of the key features of the market for this commodity, including the role that time lags play in the formation of price volatility. Various demand reduction and substitution strategies and technologies are explored, and potential external shocks are simulated to investigate how price and the associated industry respond. Sensitivity analysis performed by considering key model parameters indicates that the time constant related to the formation of traders’ expectations of future market prices embedded in the proposed price discovery mechanism has a strong influence on both the amplitude and frequency of price peaks. One particularly interesting and timely scenario simulated is the possibility of the ending of the “Megatons to Megawatts” program, in which the USA agreed to buy down-blended uranium from former Soviet nuclear warheads for use in power production. This agreement has not been formally renewed and we find that in the absence of new substitute sources this could cause a significant rise in uranium prices. Finally, our analysis leads us to believe that uranium resource scarcity will not pose any significant challenges until the second half of the twenty first century at the earliest, even if high uranium demand projections are realized.
