description: We describe synthesis of submicron Y3Fe5O12 (YIG) films sputtered on GaAs-based substrates and present results of the investigation of ferromagnetic resonance (FMR), spin wave propagation and interaction between spin excitations and 2D electrons in interface layer in YIG / AlOx / GaAs-heterostructures. It is found that the contribution of the relaxation process to the FMR linewidth is about 2 % of the linewidth ΔH. At the same time, for all samples FMR linewidths are high. Sputtered YIG films have magnetic inhomogeneity, which gives the main contribution to the FMR linewidth. Transistor structures with two-dimensional electron gas (2DEG) channels in AlOx / GaAs interface governed by YIG-film spin excitations are designed. An effective influence of spin excitations on the current flowing through the GaAs 2DEG channel is observed. Light illumination results in essential changes in the FMR spectrum. It is found that an increase of the 2DEG current leads to an inverse effect, which represents essential changes in the FMR spectrum.

description: We analyze how string theory dualities may be described in M theory. T dualities arise from scalar-vector dualities in the worldvolume of the membrane of M theory. ``Electric-magnetic'' dualities arise from a duality transformation in M theory compactified on a 3-torus, which takes the membrane into a fivebrane wrapped around the 3-torus.

Возможная гипотеза соответствия фундаментальным понятиям науки определенных множеств чисел — от целых до мнимых

description: Отрезок числовой прямой можно поставить во взаимно-однозначное соответствие с отрезком реального пространства, так как оба отрезка непрерывны. Однако множество элементов времени счетно, ибо в противном случае исключается течение самого времени. При этом основная проблема заключается в следующем. Мы имеем: а) счетные множества элементов времени и элементов физических взаимодействий; б) несчетные множества элементов реального пространства и среды, его заполняющей; в) недостаток элементов времени у квантовой частицы, чтобы двигаться темпорально, и избыток элементов пространства, чтобы двигаться траекторно. Решение проблемы движения в пространстве, по нашему мнению, заключается в постулировании мнимости элементарного перемещения микрообъекта с учетом того, что между двумя соседними элементами пространства всегда существуют элементы пространства. Предложен онтологический проект гипотезы соответствия фундаментальным понятиям определенных множеств чисел.

description: No abstracts are to be cited without prior reference to the author.Size or ecosystem biomass energy based spectral ecosystem models can help us understand the efficiency of the ecosystems. In this work, we examine how the nutrient donor and acceptor interaction govern the efficiency of the ecosystem. Following earlier size based models we pose a minimal model which will allow a study the difference in efficiency of two models which only differ in the size-dependent predator-prey interaction characteristics. We first present a hierarchy of simple spectral biomass energy models starting with local interactions, ande leading up to a new non-local but linear spectral ecosystem model. It is shown that predator-prey interaction characteristics make the ecosystem more efficient. They also introduce inherent intrinsic time variability, particularly when the size-spectra of an ecosystem gets perturbed. A local perturbation at very small sizes is shown to introduce variability at larger sizes.

description: Unitary group branchings appropriate to the calculation of local invariants of density matrices of composite quantum systems are formulated using the method of $S$-function plethysms. From this, the generating function for the number of invariants at each degree in the density matrix can be computed. For the case of two two-level systems the generating function is $F(q) = 1 + q + 4q^{2} + 6 q^{3} + 16 q^{4} + 23 q^{5} + 52 q^{6} + 77 q^{7} + 150 q^{8} + 224 q^{9} + 396 q^{10} + 583 q^{11}+ O(q^{12})$. Factorisation of such series leads in principle to the identification of an integrity basis of algebraically independent invariants. This note replaces Appendix B of our paper\cite{us} J Phys {\bf A33} (2000) 1895-1914 (\texttt{quant-ph/0001076}) which is incorrect.

description: No abstracts are to be cited without prior reference to the author.European fisheries management is already strongly influenced by a spatial approach: (1) output/input restrictions like setting the total allowable catches (TACs) or effort quotas (days at sea) by spatial management units, (2) setting closed areas to protect commercial species at vulnerable stages in their life cycles, (3) technical conservation measures like gear regulations - especially mesh sizes – that are varied regionally to take account of differing conditions. One of the ways of approaching the fisheries as a spatial resource could be based on the concept of Essential Fish Habitat (EFH) which is described as a subset of all habitats occupied by a species, and is defined as those waters and substrate necessary to fish for spawning, breeding, feeding, or growth to maturity. The aim of this paper is to discuss some problems related to practical implementation of EFH in relation to the Baltic fisheries management. Attempt was made to visualize the spatial distribution of the Baltic herring’s potential spawning and nursery habitats along the Estonian coast of the Gulf of Finland. In addition to that the spatial visualization of the hydroacoustic data on the Central Baltic herring was done to gain better insight into dynamics of the fishable stock distribution and variation within its large stock unit (ICES SD 25-29, 32; excluding the Gulf of Riga herring).

Although a number of coincidences and similarities emerge between them and certain algebraic curves related to triangular billiards, their meaning remains obscure. In an attempt to go beyond the su(3) case, we show that any rational conformal field theory determines canonically a Riemann surface.

description: Logical formalisms for reasoning about relations between spatial regions play a fundamental role in geographical information systems, spatial and constraint databases, and spatial reasoning in AI. In analogy with Halpern and Shoham's modal logic of time intervals based on the Allen relations, we introduce a family of modal logics equipped with eight modal operators that are interpreted by the Egenhofer-Franzosa (or RCC8) relations between regions in topological spaces such as the real plane. We investigate the expressive power and computational complexity of logics obtained in this way. It turns out that our modal logics have the same expressive power as the two-variable fragment of first-order logic, but are exponentially less succinct. The complexity ranges from (undecidable and) recursively enumerable to highly undecidable, where the recursively enumerable logics are obtained by considering substructures of structures induced by topological spaces. As our undecidability results also capture logics based on the real line, they improve upon undecidability results for interval temporal logics by Halpern and Shoham. We also analyze modal logics based on the five RCC5 relations, with similar results regarding the expressive power, but weaker results regarding the complexity.

Why Are There Dwarf Spheroidal Galaxies?
Creators: name: Cen, Renyue
Publisher: name: arXiv
Year: 2000
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: There appears to exist a conflict between the standard structure formation theory and the existence of the faint dwarf spheroidal galaxies in the Local Group. Theoretical considerations suggest that a cold dark matter universe has been a very hostile place for the formation of small galaxies. In particular, gas would not have been able to cool and condense to form stars inside dark matter halos with a velocity dispersion <10km/s since before the cosmological reionization epoch. In other words, one should not expect to see any major star formation activities in dwarf galaxies with a velocity dispersion <10km/s during the past 12Gyr, according to the current structure formation theory. The real universe, on the other hand, shows that all dwarf spheroidal galaxies in the Local Group have velocity dispersions <10km/s and extended and recent star formation activities are quite common in them. This apparent conflict between cold dark matter models and local observations can be resolved, if one allows the cold dark matter particles to decay relatively recently. The resolution comes about in that the dwarf spheroidal galaxies with a velocity dispersion of \~10km/s seen today were born, in this picture, in a small fraction of halos with a velocity dispersion of ~20km/s, where gas can be retained and is able to cool and contract to form stars. The presently observed lower velocity dispersion ~10km/s of these dwarf spheroidal galaxies is a consequence of the decay of one half of the dark matter in and subsequent expansion of the halos since redshift z~2.

description: The aim of this paper is to address the question: Can an artificial neural network (ANN) model be used as a possible characterization of the power of the human mind? We will discuss what might be the relationship between such a model and its natural counterpart. A possible characterization of the different power capabilities of the mind is suggested in terms of the information contained (in its computational complexity) or achievable by it. Such characterization takes advantage of recent results based on natural neural networks (NNN) and the computational power of arbitrary artificial neural networks (ANN). The possible acceptance of neural networks as the model of the human mind's operation makes the aforementioned quite relevant.

description: Grain boundaries in graphene are inherent in wafer-scale samples prepared by chemical vapor deposition. They can strongly influence the mechanical properties and electronic and heat transport in graphene. In this work, we employ extensive molecular dynamics simulations to study thermal transport in large suspended polycrystalline graphene samples. Samples of different controlled grain sizes are prepared by a recently developed efficient multiscale approach based on the phase field crystal model. In contrast to previous works, our results show that the scaling of the thermal conductivity with the grain size implies bimodal behaviour with two effective Kapitza lengths. The scaling is dominated by the out-of-plane (flexural) phonons with a Kapitza length that is an order of magnitude larger than that of the in-plane phonons. We also show that in order to get quantitative agreement with the most recent experiments, quantum corrections need to be applied to both the Kapitza conductance of grain boundaries and the thermal conductivity of pristine graphene and the corresponding Kapitza lengths must be renormalized accordingly.

description: No abstracts are to be cited without prior reference to the author.The marine environment of the Eastern English Channel is a significant economic resource that supports a number of human-based activities, such as tourism and recreation, international ports and shipping, and the extraction of both living and non-living resources. In addition to human use, the region supports a number of important marine biological features. Responsible and integrated management aided by information systems and tools capable of assisting decision-making is essential for the construction of policies to ensure the sustainable exploitation of these marine resources. MARXAN and Zonation are two computer programmes that deliver decision support for reserve system design. They find reasonably efficient solutions to the problem ofselecting a system of spatially cohesive sites that meet a suite of biodiversity targets. The aim ofthis study is to develop a tentative conservation plan for the eastern English Channel using both MARXAN/CLUZ and ZONATION. These will be used to identify important sites for conserving biodiversity, whilst using anthropological, economic and legal data to minimise potential opportunity costs. Different scenarios with varying target thresholds will be explored. A comparison between the two programmes will be made, both in terms of ease of use and results obtained

description: Objective: Treatment intensification with additional anti-diabetic agents is recommended in type 2 diabetes (T2D) for patients inadequately controlled on metformin monotherapy. The present network meta-analysis (NMA) evaluated comparative efficacy and safety of once-weekly semaglutide and sodium-glucose co-transporter 2 inhibitors (SGLT-2is) in T2D patients inadequately controlled with metformin. Methods: Randomized controlled trials with ≥20 weeks duration were searched in EMBASE, MEDLINE, and CENTRAL. Primary efficacy outcomes were: change from baseline in HbA1c, weight, systolic blood pressure (SBP), post-prandial blood glucose (PPG), and fasting blood glucose (FPG). Treatment effects at 26 (±4) weeks were compared using Bayesian NMAs. Meta-regression and sensitivity analysis were used to address the trial heterogeneity. Results: Eight trials were found eligible for this NMA. Statistically significant reductions in HbA1c were observed with both 1.0 mg and 0.5 mg doses of once-weekly semaglutide when compared to SGLT-2is. The mean differences in change from baseline in HbA1c for once-weekly semaglutide 1.0 mg vs SGLT-2is ranged from −0.66% for canagliflozin 300 mg (95% Credible Intervals [CrI]: −0.82, −0.50%) to −1.11% for dapagliflozin 5 mg (95% CrI: −1.37, −0.85%). Once-weekly semaglutide 1.0 mg performed significantly better than all SGLT-2is of interest in reducing weight and improving FPG levels: however, SBP reduction was not statistically differentiable. Results of sensitivity analysis and meta-regressions aligned with base-case results. NMAs were not possible for PPG and safety outcomes, due to lack of data. Conclusion: Once-weekly semaglutide treatment is significantly better compared to SGLT-2is in achieving adequate glycemic control in T2D patients inadequately controlled with metformin monotherapy.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We present an alternative scheme for the generation of a 2-qubit quantum gate interaction between laser-cooled trapped ions. The scheme is based on the AC Stark shift (lightshift) induced by laser light resonant with the ionic transition frequency. At {\it specific} laser intensities, the shift of the ionic levels allows the resonant excitation of transitions involving the exchange of motional quanta. We compare the performance of this scheme with respect to that of related ion-trap proposals and find that, for an experimental realisation using travelling-wave radiation and working in the Lamb-Dicke regime, an improvement of over an order of magnitude in the gate switching rate is possible.

description: The electric field gradient (EFG) tensor at the $^{75}$As site couples to the orbital occupations of the As p-orbitals and is a sensitive probe of local nematicity in BaFe$_2$As$_2$. We use nuclear magnetic resonance to measure the nuclear quadrupolar splittings and find that the EFG asymmetry responds linearly to the presence of a strain field in the paramagnetic phase. We extract the nematic susceptibility from the slope of this linear response as a function of temperature and find that it diverges near the structural transition in agreement with other measures of the bulk nematic susceptibility. Our work establishes an alternative method to extract the nematic susceptibility which, in contrast to transport methods, can be extended inside the superconducting state.

description: No abstracts are to be cited without prior reference to the author.The trophic-level based ecosystem modelling approach is articulated around the idea that an ecosystem can be represented by its biomass distribution across trophic levels (TL). Thus, trophic ecosystem functioning can be modelled as a continuous flow of biomass surging up the food web, from lower to higher trophic levels, because of predation and ontogenetic processes. Such an approach, wherein species as such disappear, may be regarded as constituting the ultimate stage in the use of the trophic level metric for ecosystem modelling, providing a simplified, but potentially useful caricature of ecosystem functioning and impact of fishing. First, we propose the EcoTroph model, based on simple assumptions and equations, as a theoretical extension of the Ecopath with Ecosim (EwE) approach. We simulate fishing impact on a virtual ecosystem and show that the model is able to mimic the effects of various exploitation patterns on ecosystem biomass expected from theory. Particularly, the model provides consistent relationships between catches or biomass and fishing mortalities; it may exhibit complex patterns, e.g., cascading effects and 'fishing down the food web'; and it provides the theoretical basis to explain the effect of strong top-down controls and fast flow kinetics on ecosystem resilience. Using an inverse form of the EcoTroph model, we also present the Catch Trophic Spectrum Analysis (CTSA), as a method for estimating biomass and fishing mortalities at the ecosystem scale. We show that such a method may be seen as the 'VPA' (Virtual Population Analysis) of ecosystem approaches and provides robust estimates when catches per trophic level and primary or secondary production are known. We illustrate the usefulness of the trophic-level based approach through the Guinean ecosystem as a case study, where a fast and strong increase in the fishing pressure occurred over the past 25 years. Biomass estimates from CTSA appear consistent with results of an independent EwE model. Using the diagnostic tools of EcoTroph, we show that increasing fishing efforts led to a three-fold decrease in the biomass of the higher trophic levels, inducing an over-exploitation for these levels and a significant decrease in the mean TL of biomass and catches, which confirm and generalize previous single species assessments. Forecasting suggests that higher yields might be obtained in exploiting lower trophic levels, but this would induce a higher impact on the ecosystem and a degradation of its health.

description: We investigate different strategies suitable to generate pure heralded single photons through spontaneous parametric down-conversion, comparing the counter-propagating geometry studied in [1] with more conventional co-propagating configurations which enhance the purity of the heralded photon state through the technique of group-velocity matching. Our analysis is based on the correlation of twin photons in the temporal domain,a non-standard approach that provides a physical view of the mechanisms that permit to eliminate the temporal entanglement of the state and to generate high-purity heralded photons. The Schmidt number associated to the temporal modes, which provides a more quantitative estimate of the purity, is then calculated. The efficiency of the various strategies and the individual properties of the heralded photons thereby generated are also compared.

description: We present Sunyaev-Zel'dovich Effect (SZE) imaging observations of three distant (z > 0.8) and highly X-ray luminous clusters of galaxies, Cl1226+33, Cl0152-13 and MS1054-03. Two of the clusters, Cl1226+33 and Cl0152-13, were recently discovered in deep ROSAT x-ray images. Their high X-ray luminosity suggests that they are massive systems which, if confirmed, would provide strong constraints on the cosmological parameters of structure formation models. Our Sunyaev-Zel'dovich Effect data provide confirmation that they are massive clusters similar to the well studied cluster MS1054-03. Assuming the clusters have the same gas mass fraction as that derived from SZE measurements of eighteen known massive clusters, we are able to infer their mass and electron temperature from the SZE data. The derived electron temperatures are 9.8, 8.7, and 10.4 keV, respectively, and we infer total masses of ~2 x 10^14 h^-1 Msun within a radius of 65 arcsec (340 h^{-1} kpc) for all three clusters. For Cl0152-13 and MS1054-03 we find good agreement between our SZE derived temperatures and those inferred from X-ray spectroscopy. No X-ray derived temperatures are available for Cl1226+33, and thus the SZE data provide the first confirmation that it is indeed a massive system. The demonstrated ability to determine cluster temperatures and masses from SZE observations without access to X-ray data illustrates the power of using deep SZE surveys to probe the distant universe.

description: No abstracts are to be cited without prior reference to the author.Thornback ray Raja clavata is the dominant skate species in the southern North Sea (with the stock extending into the eastern English Channel) and is an important target and bycatch species for inshore fisheries in the Greater Thames Estuary. Preliminary assessments, using survey data collected during the International Bottom Trawl Survey (IBTS), indicated that the distribution and abundance of thornback ray had declined markedly in the North Sea as a whole. Although it became apparent that some of the IBTS data were compromised by confusion between thornback ray and thorny skate Amblyraja radiata, more recent studies still indicate a decline in the distribution of thornback ray. Despite this longer-term decline in geographical extent, survey catches in the south-western North Sea have increased in recent years. Given the general concern over the status of the stock, and subsequent management measures brought in during 2007, a one-year Fishery Science Partnership (FSP) project was initiated to collect further data on this stock, using commercial inshore vessels. The objectives were: to examine discard survival of skates caught in gillnet, longline and trawl fisheries, to determine size and species compositions of skates, and to collect other biological information. These data, including tag returns collected to date, are presented and contrasted with data from annual stock monitoring surveys (using beam trawl and GOV trawl), and from young fish surveys (undertaken on inshore vessels in the same area as our study). The benefits of dedicated inshore surveys in this area are discussed.

description: We prove the uncertainty relation $T_{\triangle V}\triangle m\stackrel{>}{\sim }2π\hbar /c^2,$ which is realized on a statistical mechanical level for an ensemble of events in $(1+D)$-dimensional spacetime with motion parametrized by an invariant ``proper time'' $τ,$ where $T_{\triangle V}$ is the average passage interval in $τ$ for the events which pass through a small (typical) $(1+D)$-volume $\triangle V,$ and $\triangle m$ is the dispersion of mass around its on-shell value in such an ensemble. We show that a linear mass spectrum is a completely general property of a $(1+D)$-dimensional off-shell theory.

description: This article presents a novel class of control policies for networked control of Lyapunov-stable linear systems with bounded inputs. The control channel is assumed to have i.i.d. Bernoulli packet dropouts and the system is assumed to be affected by additive stochastic noise. Our proposed class of policies is affine in the past dropouts and saturated values of the past disturbances. We further consider a regularization term in a quadratic performance index to promote sparsity in control. We demonstrate how to augment the underlying optimization problem with a constant negative drift constraint to ensure mean-square boundedness of the closed-loop states, yielding a convex quadratic program to be solved periodically online. The states of the closed-loop plant under the receding horizon implementation of the proposed class of policies are mean square bounded for any positive bound on the control and any non-zero probability of successful transmission.

description: In this article it is presented an FPGA based $M$ulti-$V$oltage $T$hreshold (MVT) system which allows of sampling fast signals ($1-2$ ns rising and falling edge) in both voltage and time domain. It is possible to achieve a precision of time measurement of $20$ ps RMS and reconstruct charge of signals, using a simple approach, with deviation from real value smaller than 10$\%$. Utilization of the differential inputs of an FPGA chip as comparators together with an implementation of a TDC inside an FPGA allowed us to achieve a compact multi-channel system characterized by low power consumption and low production costs. This paper describes realization and functioning of the system comprising 192-channel TDC board and a four mezzanine cards which split incoming signals and discriminate them. The boards have been used to validate a newly developed Time-of-Flight Positron Emission Tomography system based on plastic scintillators. The achieved full system time resolution of $σ$(TOF) $\approx 68$ ps is by factor of two better with respect to the current TOF-PET systems.

description: Cooperative effects in the fluorescence of two dipole-interacting atoms, with macroscopic quantum jumps (light and dark periods), are investigated. The transition rates between different intensity periods are calculated in closed form and are used to determine the rates of double jumps between periods of double intensity and dark periods, the mean duration of the three intensity periods and the mean rate of their occurrence. We predict, to our knowledge for the first time, cooperative effects for double jumps, for atomic distances from one and to ten wave lengths of the strong transition. The double jump rate, as a function of the atomic distance, can show oscillations of up to 30% at distances of about a wave length, and oscillations are still noticeable at a distance of ten wave lengths. The cooperative effects of the quantities and their characteristic behavior turn out to be strongly dependent on the laser detuning.

description: A fundamental problem faced in the design of almost all packet networks is that of efficient operation--of reliably communicating given messages among nodes at minimum cost in resource usage. We present a solution to the efficient operation problem for coded packet networks, i.e., packet networks where the contents of outgoing packets are arbitrary, causal functions of the contents of received packets. Such networks are in contrast to conventional, routed packet networks, where outgoing packets are restricted to being copies of received packets and where reliability is provided by the use of retransmissions. This thesis introduces four considerations to coded packet networks: 1. efficiency, 2. the lack of synchronization in packet networks, 3. the possibility of broadcast links, and 4. packet loss. We take these considerations and give a prescription for operation that is novel and general, yet simple, useful, and extensible.

description: Мы стоим перед фактом пересмотра полноты физического бытия вещей и явлений в физической картине мира. Опыт создания квантовой механики показал, что нельзя создать логически последовательную квантовую теорию микромира без апелляции к сознанию «наблюдателя». В философском плане проблема наблюдателя (с его сознанием) предстаёт как проблема отношения между субъектом и объектом. До поры до времени можно было как-то отмахиваться от этой проблематики, но как только физики приступили к созданию квантовых компьютеров, встал вопрос о сознательно избираемой цели таких вычислений. Целеполагание вычислительного процесса связано, в свою очередь, с вероятностной оценкой получаемого числового результата. Мы видим, как цель, представленная в будущем времени, мотивирует деятельность субъекта и вместе с тем детерминирует, с той или иной долей вероятности, квантовый процесс. Вывод, который делается в статье, состоит в том, что приходится отказываться от традиционной гносеологической установки на каузальную замкнутость физического бытия вещей и явлений.

description: We show that the open membrane action on $T^3\times S^1/Z^2$ is equivalent to the closed membrane action on K3. The main difference between the two actions is that one generates the KK modes in the worldvolume action which is the strong coupling limit of \IIA\ while the other action generates the KK modes in a worldsheet action. Thus explaining membrane-string duality in D=7, which naturally leads to string-string duality in D=6.
