Studies on soil permeability
Creators: name: Mante, Eugene Frederick Gyampo
Publisher: name: University of British Columbia
Year: 2011

description: Laboratory tests were performed to investigate the possibilities of using a modified form of Steinbrenner’s apparatus to estimate the intrinsic permeabilities of four different soils. Readings were taken on soils at the same moisture content but different void ratios; and on soils at the same void ratio but different moisture contents. Straight line graphs of positive slopes were obtained when the logarithm of intrinsic permeability was plotted against void ratio for peat, a sandy loam and synthetic soils. Results were extremely variable in the case of a clay soil. An attempt was made to relate the permeability estimated with the apparatus and using air as the permeant to the permeability estimated with water on core samples. Some correlation was observed between the two types of tests on the sandy loam and synthetic soils; but there was no correlation in the case of the peat and clay soils. Results, in general, were variable.

description: There is a long-standing discrepancy between galaxy cluster masses determined from X-ray and gravitational lensing observations of which Abell 1689 is a well-studied example. In this work we take advantage of 180 ks of Chandra X-ray observations and a new weak gravitational study based on a Hubble Space Telescope mosaic covering the central 1.8 Mpc x 1.4 Mpc to eliminate the mass discrepancy. In contrast to earlier X-ray analyses where the very circular surface brightness has been inferred as Abell 1689 being spherically symmetric and in hydrostatic equilibrium, a hardness ratio map analysis reveals a regular and symmetric appearing main clump with a cool core plus some substructure in the North Eastern part of the cluster. The gravitational lensing mass model supports the interpretation of Abell 1689 being composed of a main clump, which is possibly a virialized cluster, plus some substructure. In order to avoid complications and mis-interpretations due to X-ray emission from the substructure, we exclude it from the mass reconstruction. Comparing X-ray and lensing mass profiles of the regular main part only, shows no significant discrepancy between the two methods and the obtained mass profiles are consistent over the full range where the mass can be reconstructed from X-rays (out to approx. 1 Mpc). The obtained cluster mass within approx. 875 kpc derived from X-rays alone is 6.4 plus/minus 2.1 x 10^14 solar masses compared to a weak lensing mass of 8.6 plus/minus 3.0 x 10^14 solar masses within the same radius.

description: We present multi-molecular line maps obtained with the Mopra Telescope towards the southern giant molecular cloud (GMC) complex G333, associated with the HII region RCW 106. We have characterised the GMC by decomposing the 3D data cubes with GAUSSCLUMPS, and investigated spatial correlations among different molecules with principal component analysis (PCA). We find no correlation between clump size and line width, but a strong correlation between emission luminosity and line width. PCA classifies molecules into high and low density tracers, and reveals that HCO+ and N2H+ are anti-correlated.

description: Benchmark brown dwarfs are those objects for which fiducial constraints are available, including effective temperature, parallax, age, metallicity. We searched for new cool brown dwarfs in 186 sq.deg. of the new area covered by the data release DR5+ of the UKIDSS Large Area Survey. Follow-up optical and near-infrared broad-band photometry, and methane imaging of four promising candidates, revealed three objects with distinct methane absorption, typical of mid- to late-T dwarfs, and one possibly T4 dwarf. The latest-type object, classified as T8-9, shares its large proper motion with Ross 458 (BD+13o2618), an active M0.5 binary which is 102" away, forming a hierarchical low-mass star+brown dwarf system. Ross 458C has an absolute J-band magnitude of 16.4, and seems overluminous, particularly in the K band, compared to similar field brown dwarfs. We estimate the age of the system to be less than 1 Gyr, and its mass to be as low as 14 Jupiter masses for the age of 1 Gyr. At 11.4 pc, this new late T benchmark dwarf is a promising target to constrain the evolutionary and atmospheric models of very low-mass brown dwarfs. We present proper motion measurements for our targets and for 13 known brown dwarfs. Two brown dwarfs have velocities typical of the thick disk and may be old brown dwarfs.

description: Publicar instrumentos de gestão de documentos significa compartilhar e difundir conhecimentos próprios de processos burocráticos, controle de informações e preservação da memória institucional. Com a presente edição do Plano de Classificação e Tabela de Temporalidade de Documentos da Unesp: Atividades-Fim, chega-se ao 3.º volume da coleção destinada aos instrumentos de gestão de documentos na Unesp. Esse é um trabalho iniciado com a publicação do Manual de Normas Processuais da Unesp, em 2015, seguido pela publicação do Plano de Classificação e Tabela de Temporalidade de Documentos da Unesp: Atividades-Meio, em 2016, que agora tem continuidade neste livro. Foi percorrido um longo caminho para a concretude da ferramenta de gestão ora apresentada, entre o levantamento da produção documental de 34 unidades universitárias, pesquisas bibliográfica e legislativa, sistematização de dados, estudo e avaliação de documentos. Os desafios enfrentados para a contextualização de uma universidade de alta complexidade burocrática, estruturada em um modelo multicâmpus, podem ser comprovados nos resultados presentes neste livro. Aprovado pelo Conselho Universitário, instância decisória superior da Universidade, e publicado no Diário Oficial em forma da Resolução Unesp nº 09, de 08 de fevereiro de 2018, a entrada em vigor do Plano de Classificação e da Tabela de Temporalidade de Atividades-Fim foi imediata, pautando a partir desse momento grande parte do processo de avaliação documental na Unesp. Como resultado, a construção do Plano de Classificação e da Tabela de Temporalidade de Atividades-Fim, ao unir-se ao Plano de Classificação e Tabela de Temporalidade de Atividades-Meio, tornou-se uma das principais ferramentas administrativas a serviço da instituição. A avaliação e a destinação conscientes dos documentos trazem benefícios de distintas ordens: seja relativos à compreensão do papel da universidade e de como esta se organiza para cumprir sua missão; seja pela transparência burocrática que proporcionam; seja pelo resguardo de direitos individuais e coletivos – condição inerente à cidadania. Dessa forma, ambos os planos e tabelas, para além da racionalização e do controle dos atos administrativos, permitem a preservação consciente do patrimônio documental arquivístico público e, consequentemente, da memória da universidade.

description: The increasing demand on battery energy storage technologies that are sustainable and efficient makes it important to assess aproduct's entire life cycle, from the extraction of raw materials to end-of-life treatment. In the context of LFP batteries, whichare increasingly employed for their safety, longevity, and better environmental performance, a lab-scale LCA of a batteryserves as a crucial tool for identifying and mitigating potential environmental hotspots stemming from its cradle-to-gateimpacts.In this particular field, there is a research gap, given the distinctive differences between laboratory-scale manufacturing andlarger-scale production. These variations encompass unique energy consumption patterns, challenges in resource utilization,and technological limitations. This study aims to investigate the amount of energy, which is utilized by equipment in dry roomoperations, and during battery cell manufacturing.A cradle-to-gate life cycle assessment is carried out for the battery cell. The functional unit considered is battery storagecapacity measured in kilowatt-hours (kWh). Battery has a mass of 26g, average voltage 3.2V, and has an energy density of92Wh/kg. Primary data is from the pilot line and respective background database processes is from Ecoinvent 3.9.1. Twoscenarios were considered, where in real time scenario with 5 cells per day equal capacity 11.6. If the lab unit had a continuousscale of production, it could produce 16 cells per day with total capacity of 38.3Wh which would be the ideal case scenario.For the manufacture of 5 LFP battery cells, the highest unit process energy consumption comes from the dry and formationroom counting up to 86% of total consumption. Lab-scale operations may require more thorough testing, experimentation, andprototyping, potentially resulting in higher demands on the dry and formation room’s-controlled environment. The Life cycleimpact assessment showed that there is a reduction of GWP by 69% per cell manufactured if the laboratory unit was running infull capacity (ReCiPe 2016 midpoint-H).The study makes particular recommendations for future research, such as investigating lab-scale energy dynamics in moredetail, identifying potential hotspots along with a mitigation strategy, and also taking renewable energy integration intoaccount. These intended suggestions seek to close the noted research gap and advance the continuous advancement ofenvironmentally friendly manufacturing methods.

description: Die Auswertung großer Datenmengen ist wichtig für die moderne medizinische Forschung. Die Heterogenität medizinischer Dokumentation führt jedoch häufig zu inkompatiblen Daten. Ein Lösungsansatz stellen Metadaten-Repositories (MDR) dar, die standardisierte Dokumentationen enthalten. In dieser Arbeit schlagen wir das Konzept eines pragmatischen MDRs vor, das eine automatisierte Standardisierung von Metadaten durchführt. Wir implementierten einen Prototyp und importierten 15.306 medizinische Formulare. Unsere quantitative Analyse ergab, dass es möglich ist, für strukturierte medizinische Konzepte, wie Laborwerte oder Vitalzeichen, automatisiert Standards zu bestimmen. Unsere qualitative Analyse mit zwei medizinischen Dokumentaren zeigte eine gute Qualität dieser Standards. Das Konzept des pragmatischen MDRs kann eine sinnvolle Ergänzung zu bestehenden MDRs darstellen und einen Beitrag zur Harmonisierung der medizinischen Dokumentation leisten.

description: Scope: Despite their essentiality, several studies have shown that either manganese (Mn) or zinc (Zn) overexposure may lead to detrimental health effects. Although Mn is transported by some of the SLC family transporters that translocate Zn, the role of Zn in hepatocellular Mn transport and Mn‐induced toxicity have yet to be fully characterized. Methods and Results: The human hepatoma cell line, HepG2, is utilized. Total cellular Mn and Zn amounts are determined after cells are treated with Zn 2 or 24 h prior to Mn incubation for additional 24 h with inductively coupled plasma‐based spectrometry and labile Zn is assessed with the fluorescent probe FluoZin‐3. Furthermore, mRNA expression of genes involved in metal homeostasis, and mechanistic endpoints associated with Mn‐induced cytotoxicity are addressed. These results suggest that Zn protects against Mn‐induced cytotoxicity and impacts Mn bioavailability to a great extent when cells are preincubated with higher Zn concentrations for longer duration as characterized by decreased activation of caspase‐3 as well as lactate dehydrogenase (LDH) release. Conclusions: Zn protects against Mn‐induced cytotoxicity in HepG2 cells possibly due to decreased Mn bioavailability. Additionally, mRNA expression of metal homeostasis‐related genes indicates possible underlying pathways that should to be addressed in future studies.

description: In this introduction the editors showcase the papers by way of a structured project and seek to clarify the two key concepts cited in the title. We consider the history of the idea that knowledge is an economic factor, and discuss the question of whether regions provide the relevant system of reference for knowledge-based economic development. Current transformations in university-industry-government relations at various levels can be considered as a metamorphosis in industry organization. The concept of constructed advantage will be elaborated. The various papers arising from a conference on this subject hosted by Memorial University, Newfoundland, Canada are approached from this perspective.

A Shaper for Providing Long Laser Waveforms

Publisher: name: INFN Open Access Repository
Year: 2004

description: We discuss the features of a shaping device consisting of a spectral amplitude modulator followed by a pair of diffraction gratings arranged as a linear dispersive stretcher. The system is proposed in view of transforming input short pulses into much longer target pulses.  The shaper transfers a spectral amplitude profile into a temporal profile.  The device is interesting for its mechanical simplicity, its stability to perturbations of input pulse parameters and optical apparatus alignment and finally for its capability to provide long rectangular pulses with fast rise time as required by radiofrequency electron guns.
A Proposal For Cosmic Ray Studies Involving Collaborations Between Higher Education, Research Sites and Local Area High Schools

Publisher: name: INFN Open Access Repository
Year: 2004

description: This is a proposal for a collaboration between the INFN, the Department of Physics and Astronomy of the University of Catania, and local area high schools, aimed at carrying out experimental studies in cosmic ray physics. The purpose of the collaboration is to investigate the possible involvement of high schools sites in studies related to nuclear and high energy experimental physics, and the educational aspects of such involvement. According to the idea outlined in the present proposal, the INFN/University Department site will act as a central data collection and processing institution, managing an array of scintillator-based detectors. Each high school joining the project could handle its own detector for cosmic muons, with the overall set of detectors resulting in a large array allowing the study of both local properties of the cosmic muon flux and large area correlations as well. A basic introduction to the different physics items which could be investigated in this framework is given in the present document, together with some technical aspects on how to carry out such measurements. The role of the educational aspects of the proposal is also stressed.
The Expected Detection of Dust Emission from High-Redshift Lyman Alpha Galaxies

description: Recent results have shown that a substantial fraction of high-redshift Lyman alpha galaxies contain considerable amounts of dust. This implies that Lyman alpha galaxies are not primordial, as has been thought in the past. However, this dust has not been directly detected in emission; rather it has been inferred based on extinction estimates from rest-frame ultraviolet (UV) and optical observations. This can be tricky, as both dust and old stars redden galactic spectra at the wavelengths used to infer dust. Measuring dust emission directly from these galaxies is thus a more accurate way to estimate the total dust mass, giving us real physical information on the stellar populations and interstellar medium (ISM) enrichment. New generation instruments such as the Atacama Large Millimeter Array (ALMA) and Sub-Millimeter Array (SMA), should be able to detect dust emission from some of these galaxies in the sub-mm. Using measurements of the UV spectral slopes, we derive far-infrared flux predictions for of a sample of 23 z > 4 Lyman alpha galaxies. We find that in only a few hours, we can detect dust emission from 39 +/- 22% of our Lyman alpha galaxies. Comparing these results to those found from a sample of 21 Lyman break galaxies (LBGs), we find that LBGs are on average 60% more likely to be detected than Lyman alpha galaxies, implying that they are more dusty, and thus indicating an evolutionary difference between these objects. These observations will provide better constraints on dust in these galaxies than those derived from their UV and optical fluxes alone. Undeniable proof of dust in these galaxies could explain the larger than expected Lyman alpha equivalent widths seen in many Lyman alpha galaxies today.

description: We investigate the dynamics of homogeneous phase space for single-field models of inflation. Inflationary trajectories are formally attractors in phase space, but since in practice not all initial conditions lead to them, some degree of fine tuning is required for successful inflation. We explore how the dynamics of non-canonical inflation, which has additional kinetic terms that are powers of the kinetic energy, can play a role in ameliorating the initial conditions fine tuning problem. We present a qualitative analysis of inflationary phase space based on the dynamical behavior of the scalar field. This allows us to construct the flow of trajectories, finding that trajectories generically decay towards the inflationary solution at a steeper angle for non-canonical kinetic terms, in comparison to canonical kinetic terms, so that a larger fraction of the initial-conditions space leads to inflation. Thus, non-canonical kinetic terms can be important for removing the initial conditions fine-tuning problem of some small-field inflation models.

The spark spectra of zinc
Creators: name: Dick, Kenneth Anderson
Publisher: name: University of British Columbia
Year: 2011

description: The spark spectra of zinc have been photographed in the region between 990 Å and 2590 Å using a condensed spark in helium as source. Exposures were taken using a Hilger large quartz prism spectrograph and a 3 meter normal incidence vacuum grating spectrograph of local design. Of 1000 lines measured, some 228 were classified in the spectra Zn I, Zn II, and Zn III on the basis of square arrays constructed using energy levels from Moore's "Atomic Energy levels," volume II (1952). Also, 67 lines were classified in the third spark spectrum of zinc, Zn IV, enabling assignment of relative energies to 8 even levels belonging to the configuration 3d⁸ 4s and to 27 odd levels belonging to the configuration 3d⁸ 4p, In addition, use was made of 25 lines measured by Bloch and Bloch (1936) in the region below 500 Å in determination of the ground state 3d⁹²D.

description: Since the structure of space-time at very short distances is believed to get modified possibly due to noncommutativity effects and as the Dirac Quantization Condition (DQC), $μe = \frac{N}{2}\hbar c$, probes the magnetic field point singularity, a natural question arises whether the same condition will still survive. We show that the DQC on a noncommutative space in a model of dynamical noncommutative quantum mechanics remains the same as in the commutative case to first order in the noncommutativity parameter $θ$, leading to the conjecture that the condition will not alter in higher orders.

description: Computing for the Large Hadron Collider (LHC) at CERN arguably started shortly after the commencement of data taking at the previous machine – LEP[1] – some would argue it was even before. Without specifying an exact date, it was certainly prior to when today’s large(st) collaborations, namely ATLAS and CMS, had formed and been approved and before the LHC itself was given the official go-ahead at the 100th meeting of the CERN Council in 1995. Just as with LEP computing, the challenges looked at some (many) points both insurmountable and the costs unaffordable. At the time of writing, we have perhaps only reached a false summit but we are now joined by other disciplines facing similar issues. Thus, we can look forward to the future – both of the LHC and any eventual “successor” machines, with cautious optimism. [1] The story of computing for LEP is at least partially told in https://zenodo.org/record/4139583.

description: Since 2001, the radio quasar 3C 454.3 has undergone a period of high optical activity, culminating in the brightest optical state ever observed, during the 2004-2005 outburst. The Whole Earth Blazar Telescope (WEBT) consortium has carried out several multifrequency campaigns to follow the source behaviour. The GLAST-AGILE Support Program (GASP) was born from the WEBT to provide long-term continuous optical-to-radio monitoring of a sample of gamma-loud blazars, during the operation of the AGILE and GLAST (now known as Fermi GST) gamma-ray satellites. The main aim is to shed light on the mechanisms producing the high-energy radiation, through correlation analysis with the low-energy emission. Thus, since 2008 the monitoring task on 3C 454.3 passed from the WEBT to the GASP, while both AGILE and Fermi detected strong gamma-ray emission from the source. We present the main results obtained by the GASP at optical, mm, and radio frequencies in the 2008-2009 season, and compare them with the WEBT results from previous years. An optical outburst was observed to peak in mid July 2008, when Fermi detected the brightest gamma-ray levels. A contemporaneous mm outburst maintained its brightness for a longer time, until the cm emission also reached the maximum levels. The behaviour compared in the three bands suggests that the variable relative brightness of the different-frequency outbursts may be due to the changing orientation of a curved inhomogeneous jet. The optical light curve is very well sampled during the entire season, which is also well covered by the various AGILE and Fermi observing periods. The relevant cross-correlation studies will be very important in constraining high-energy emission models.

description: Debris discs - analogous to the Asteroid and Kuiper-Edgeworth belts in the Solar system - have so far mostly been identified and studied in thermal emission shortward of 100 um. The Herschel space observatory and the SCUBA-2 camera on the James Clerk Maxwell Telescope will allow efficient photometric surveying at 70 to 850 um, which allow for the detection of cooler discs not yet discovered, and the measurement of disc masses and temperatures when combined with shorter wavelength photometry. The SCUBA-2 Unbiased Nearby Stars (SUNS) survey and the DEBRIS Herschel Open Time Key Project are complimentary legacy surveys observing samples of ~500 nearby stellar systems. To maximise the legacy value of these surveys, great care has gone into the target selection process. This paper describes the target selection process and presents the target lists of these two surveys.

description: While there is significant potential for driving automation to increase traffic safety and enhance comfort, it is important that these systems are designed in such a way that drivers are supported in building a correct understanding of the system's capabilities and limitations. Hence, it is necessary to understand both the process by which drivers understand a driving automation system and the factors that influence their perception. During three workshops, six practitioners participated in a participatory action research study around a design use case, aiming to enhance mode awareness in a vehicle offering several levels of automation. This facilitated the development of a card deck, which supports practitioners to 1. explore possible solutions driven through a systematic approach, 2. identify areas of improvement through applying the lens of the user, 3. ideate and evaluate design decisions through a guided process.

description: Biological membranes mainly consist of lipids and proteins. While the proteins have many functions as single molecules, the membrane as a whole displays physical properties that cannot be explained on the single molecule level. For example, membranes show melting events, phase behavior, and elasticity. Biomembranes adapt their composition such that the physical properties are maintained when the external conditions change. This gives a role to changes in composition, to temperature and pressure. This article introduces into the physics of membranes as a whole and shows how phenomena as permeability, pulse propagation and the effect of anesthetics arise.

description: We calculate the running of the three coupling constants in cosmological, topologically massive 3d gravity. We find that ν, the dimensionless coefficient of the Chern-Simons term, has vanishing beta function. The flow of the cosmological constant and Newton's constant depends on ν, and for any positive νthere exist both a trivial and a nontrivial fixed point.

Stability of a Spherical Accretion Shock with Nuclear Dissociation

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We examine the stability of a standing shock wave within a spherical accretion flow onto a gravitating star, in the context of core-collapse supernova explosions. Our focus is on the effect of nuclear dissociation below the shock on the linear growth, and non-linear saturation, of non-radial oscillations of the shocked fluid. We combine two-dimensional, time-dependent hydrodynamic simulations using FLASH2.5 with a solution to the linear eigenvalue problem, and demonstrate the consistency of the two approaches. Previous studies of this `Standing Accretion Shock Instability' (SASI) have focused either on zero-energy accretion flows without nuclear dissociation, or made use of a detailed finite-temperature nuclear equation of state and included strong neutrino heating. Our main goal in this and subsequent papers is to introduce equations of state of increasing complexity, in order to isolate the various competing effects. In this work we employ an ideal gas equation of state with a constant rate of nuclear dissociation below the shock, and do not include neutrino heating. We find that a negative Bernoulli parameter below the shock significantly lowers the real frequency, growth rate, and saturation amplitude of the SASI. A decrease in the adiabatic index has similar effects. The non-linear development of the instability is characterized by an expansion of the shock driven by turbulent kinetic energy at nearly constant internal energy. Our results also provide further insight into the instability mechanism: the rate of growth of a particular mode is fastest when the radial advection time from the shock to the accretor overlaps with the period of a standing lateral sound wave. The fastest-growing mode can therefore be modified by nuclear dissociation.

THE EFFECTIVENESS OF GAMIFICATION IN ENGLISH GRAMMAR LESSONS
Creators: name: Quranbayeva, Mashhura

Publisher: name: Zenodo
Year: 2025

description: The general study of this research is situated at the intersection of educational technology and language acquisition, specifically examining how gamification can enhance English grammar instructions. Gamification is an educational strategy that uses game mechanics and components to enhance learning in order to increase motivation, engagement, and retention of information. It entails using games or activities that resemble games to reinforce and teach academic concepts and abilities. The ability to understand grammar is crucial for language fluency, yet many students find it difficult to grasp the intricate structures and rules that underpin grammatical ideas. Grammar issues among students constitute a major barrier to learning a language. The aim of this study is to determine, based on earlier research, the efficacy of game-based learning strategies in grammar acquisition. Key studies highlight that gamification, overcomes conventional barriers like nervousness and lack of confidence by including features like rewards, challenges, and interactive tasks into learning experiences.
Lead Assimilation and it's Variability in the Snail Helix aspersa
Creators: name: Richmond, Larry.
Publisher: name: London South Bank University
Year: 1994

description: Hel aspersa is known to accumulate Pb in its tissues during environmental exposure, and lose the metal when exposure ends. The effect of previous exposure to Pb on subsequent metal assimilation was investigated, together with the contribution of a range of factors to the variability in measured metal concentrations between individual snails. Snails from a number of sites, with a wide range of Pb pollution, were investigated. Assimilation of Pb from the diet was lower in He/&x aspersa from a grossly contaminated site (CP) than in animals from a ‘clean' control site (RD). High tissue Ca concentrations in the CP population were thought to be linked with an enhanced excretion efficiency for Pb, with rapid loss of Ca occuring after ingestion of Pb. Comparison of snails from several sites provided further evidence for differentiation by the CP snails in respect of Pb assimilation. Rates of uptake and the amount of variability were lower in the CP population. The main site of Pb storage, probably bound to Ca/Mg pyrophosphate granules, is in the hepatopancreas. Changes in Ca levels in the soft tissues, and possibly the shell, followed Pb exposure. The role of Ca in regulating assimilation of Pb was therefore investigated. There was no evidence of any direct correlation between dietary Ca concentrations and Pb assimilation. Genetic adaptation to high levels of environmental Pb by the CP snails was investigated in an experiment with laboratory-bred F, animals. No firm conclusions could be reached, due to high levels of variability in the data. Comparisons of data from both juveniles and adults showed similar patterns of Pb assimilation, indicating the possibility of a genetic adaptation by this population. Only CP juveniles showed any increase in fresh weight when fed on a Pb-dosed diet. The potential role of the microbial gut flora in metal assimilation was investigated in a series of experiments in which snails were fed antibiotic-dosed diets. There was no evidence that the gut flora had been altered by these treatments. Variability of metal concentrations within populations was a serious problem in all experiments. Sources of variability in the experimental work and methods of reducing their influence in future studies are examined. The implications to biological monitoring programmes and ecotoxicological studies are discussed. Modification of their Ca metabolism, together with increased rates of excretion, are thought to be the main mechanisms employed by the CP snails to reduce Pb concentrations in the tissues.

description: We study analytic descriptions of conformal immersions of the Riemann sphere S^2 into the CP^(N-1) sigma model. In particular, an explicit expression for two-dimensional (2-D) surfaces, obtained from the generalized Weierstrass formula, is given. It is also demonstrated that these surfaces coincide with the ones obtained from the Sym-Tafel formula. These two approaches correspond to parametrizations of one and the same surface in R^(N^2-1).

description: The existence of efficient ion acceleration regimes in collective laser-plasma interactions opens up the possibility to develop high-energy physics facilities in conjunction with projects for inertial confinement nuclear fusion (ICF) and neutron spallation sources. In this paper, we show that the pulse compression requests to make operative these acceleration mechanisms do not fall in contradiction with current technologies for high repetition rate ICF drivers. In particular, we discuss explicitly a solution that exploits optical parametric chirped pulse amplification and the intrinsic modularity of the lasers aimed at ICF.

description: We present a theoretical method to generate a highly accurate time-independent Hamiltonian governing the finite-time behavior of a time-periodic system. The method exploits infinitesimal unitary transformation steps, from which renormalization-group–like flow equations are derived to produce the effective Hamiltonian. Our tractable method has a range of validity reaching into frequency—and drive strength—regimes that are usually inaccessible via high-frequency ω expansions in the parameter h=ω, where h is the upper limit for the strength of local interactions. We demonstrate exact properties of our approach on a simple toy model and test an approximate version of it on both interacting and noninteracting many-body Hamiltonians, where it offers an improvement over the more well-known Magnus expansion and other high-frequency expansions. For the interacting models, we compare our approximate results to those found via exact diagonalization. While the approximation generally performs better globally than other high-frequency approximations, the improvement is especially pronounced in the regime of lower frequencies and strong external driving. This regime is of special interest because of its proximity to the resonant regime where the effect of a periodic drive is the most dramatic. Our results open a new route towards identifying novel nonequilibrium regimes and behaviors in driven quantum many-particle systems.
