description: Despite much anticipation of valleytronics as a candidate to replace the ageing CMOS-based information processing, its progress is severely hindered by the lack of practical ways to manipulate valley polarization all-electrically in an electrostatic setting. Here we propose a class of all-electric-controlled valley filter, valve and logic gate based on the valley-contrasting transport in a merging Dirac cones system. The central mechanism of these devices lies on the pseudospin-assisted quantum tunneling which effectively quenches the transport of one valley when its pseudospin configuration mismatches that of a gate-controlled scattering region. The valley polarization can be abruptly switched into different states and remains stable over semi-infinite gate-voltage windows. Colossal tunneling valley-pseudo-magnetoresistance ratio of over 10,000\% can be achieved in a valley-valve setup. We further propose a valleytronic-based logic gate capable of covering all 16 types of two-input Boolean logics. Remarkably, the valley degree of freedom can be harnessed to resurrect logical-reversibility in two-input universal Boolean gate. The (2+1) polarization states -- two distinct valleys plus a null polarization -- re-establish one-to-one input-to-output mapping, a crucial requirement for logical-reversibility, and significantly reduce the complexity of reversible circuits due to the built-in nature of valley degree of freedom. Our results suggest that the synergy of valleytronics and digital logics may provide new paradigms for valleytronic-based information processing and reversible computing.

description: We present in this letter a high resolution (22'' FWHM) extended map at 2.1mm of the Sunyaev-Zel'dovich effect toward the most luminous X-ray cluster, RXJ1347-1145. These observations have been performed with the DIABOLO photometer working at the focus of the 30m IRAM radiotelescope. We have derived a projected gas mass of $(1.1 \pm 0.1)\times 10^{14} h_{50}^{-5/2}$M$_{\odot}$ within an angular radius of $θ=74''$ (ie: projected radius of 0.6Mpc, $H_{0}=50$km/s/Mpc, $Ω_m=0.3$, $Ω_Λ=0.7$). This result matches very well the expected gas mass from the cluster models of X-ray data. With an unprecedented sensitivity level our measurement does not show significant departure from a spherical distribution. The data analysis also allows us to characterize the 2.1mm flux of a well known radio source lying in the center of the cluster: $F_{RS}(2.1\textrm{mm})=5.7\pm 1.6$mJy.

description: During the last decade there has been a huge interest in Grid technologies, and numerous Grid projects have been initiated with various visions of the Grid. While all these visions have the same goal of resource sharing, they differ in the functionality that a Grid supports, characterization, programming environments, etc. We present a new Grid system dedicated to dealing with data issues, called DGET (Data Grid Environment and Tools). DGET is characterized by its peerto- peer communication system and entity-based architecture, therefore, taking advantage of the main functionality of both systems; P2P and Grid. DGET is currently under development and a prototype implementing the main components is in its first phase of testing. In this paper we limit our description to the system architectural features and to the main differences with other systems. Keywords: Grid Computing, Peer to Peer, Peer to Peer Grid

description: Herein we report the reversible activation of CO2 by the dearomatized complex [(tBuPNP*)Ir(COE)] (1) and by the aromatized complex [(tBuPNP)Ir(C6H5)] (2) via metal-ligand cooperation (MLC) (tBuPN = 2,6-bis-(di-tert-butylphosphinomethyl)pyridine; tBuPNP* = deprotonated PNP; COE = cyclooctadiene). The [1,3]-addition of CO2 to 1 and 2 is reversible at ambient temperature. While the dearomatized complex 1 reacts readily at ambient temperature with CO2 in THF or benzene, complex 2 reacts with CO2 upon heating in benzene at 80 °C or at ambient temperature in THF. The novel aromatized complex [(tBuPNP)IrCl] (10) does not react with CO2. Based on the reactivity patterns of 1, 2, and 10 with CO2, we suggest that CO2 activation via MLC takes place only via the dearomatized species, and that in the case of 2 THF plays a role as a polar solvent in facilitating formation of the dearomatized hydrido phenyl complex intermediate (complex II).

description: We discuss heating and decoherence in traps for ions and neutral particles close to metallic surfaces. We focus on simple trap geometries and compute noise spectra of thermally excited electromagnetic fields. If the trap is located in the near field of the substrate, the field fluctuations are largely increased compared to the level of the blackbody field, leading to much shorter coherence and life times of the trapped atoms. The corresponding time constants are computed for ion traps and magnetic traps. Analytical estimates for the size dependence of the noise spectrum are given. We finally discuss prospects for the coherent transport of matter waves in integrated surface waveguides.

description: During wakefulness and deep sleep brain states, cortical neural networks show a different behavior, with the second characterized by transients of high network activity. To investigate their impact on neuronal behavior, we apply a pairwise Ising model analysis by inferring the maximum entropy model that reproduces single and pairwise moments of the neuron's spiking activity. In this work we first review the inference algorithm introduced in Ferrari,Phys. Rev. E (2016). We then succeed in applying the algorithm to infer the model from a large ensemble of neurons recorded by multi-electrode array in human temporal cortex. We compare the Ising model performance in capturing the statistical properties of the network activity during wakefulness and deep sleep. For the latter, the pairwise model misses relevant transients of high network activity, suggesting that additional constraints are necessary to accurately model the data.

description: No abstracts are to be cited without prior reference to the author.The NORWECOM ocean model system implemented with the ROMS ocean circulation model has been run to simulate conditions over the last 25 years for the North Atlantic. Modelled time series of volume fluxes, primary production and drift of cod larvae through their modelled ambient temperature have been analysed in conjunction with observational based VPA estimated time series of 3-year old cod recruits in the Barents Sea. Individual time series account for less than 50% of the recruitment variability, however a combination of simulated inflow of Atlantic water and primary production accounts for 70% of the variability with a 3-year lead. The prediction indicates an increased recruitment from 2007 to 2008 from about 450 to 700 million individuals with a standard error of near 150 million.

description: No abstracts are to be cited without prior reference to the author.The MERSEA project is funded by the European Com-mission to develop ocean and marine applications for GMES (Global Monitoring for Environment and Security). The MERSEA system is based on the assimilation of remote sensing (altimetry, sea surface temperature, sea ice, ocean colour) and in situ obser-vations (ARGO and XBT profiles) into high resolution ocean models. The system will contribute to the development of int e-grated core ocean services in Europe. Its design includes a global, as well as four regional components (Nordic, Baltic / North sea, North East Atlantic, and Mediterranean seas) which provide ocean analyses and forecasts in real time through data assimila-tion. The essential climate variables are temperature, salinity, sea level, sea ice and velocity fields, but research efforts are under-way to include bio-geochemical and ecosystem variables. The input data and forcing fields are provided by dedicated Centres. The whole system is linked through an Information Management System to guarantee easy access to users. The target delivery of the initial service is 2008, but a preliminary version of the system is in place. The Marine Core Service is delivering data, informa-tion and products on the physical environment. Such information is necessary to produce indicators on the state of the oceans, it is also a contribution and a support to agencies in charge of envi-ronmental monitoring and reporting. Integrated data products, including remote sensed and in situ data are also a useful contri-bution to ocean, climate, and fisheries research.

description: We present an ASCA discovery of diffuse hard X-ray emission from the Sgr C complex with its peak in the vicinity of the molecular cloud core. The X-ray spectrum is characterized by a strong 6.4-keV line and large absorption. These properties suggest that Sgr C is a new X-ray reflection nebula which emits fluorescent and scattered X-rays via irradiation from an external X-ray source. We found no adequately bright source in the immediate Sgr C vicinity to fully account for the fluorescence. The irradiating source may be the Galactic nucleus Sgr A*, which was brighter in the past than it is now as is suggested from observations of the first X-ray reflection nebula Sgr B2.

description: No abstracts are to be cited without prior reference to the author.The semi-enclosed NE part of the Gulf of Riga (Pärnu Bay) is a unique reproduction area for a number of marine and freshwater fishes. Relatively limited area and similar timing of spawning cause the spatial and temporal overlap of larval phase of several species. However, the Baltic herring, gobies and perch larvae dominate in that ichtyoplankton community. The study of feeding of perch and herring larvae was performed in May – July 2004 and 2005. Perch larvae started active external feeding at length of 4 mm, i.e. prior to complete utilization of yolk sack (at app.7 mm). The ingested food consisted mainly of different stages of copepod Eurytemora affinis, but included also cladocerans and pelagic larvae of benthic invertebrates. With increasing of length, the share of copepod nauplii in the food decrease gradually and after yolk utilization, the prey consisted mostly of copepod juvenile stages and adults of copepods. Herring larvae started external feeding at 6.5 mm, but never prior to complete utilization of yolk sac, when the prey consisted mostly copepod nauplii. The general trend of decreasing of small-sized food during the larval growth was similar in both cases. However, the perch tend to switch on bigger (and more diverse) food items much earlier and faster - almost at 5 mm. Also, the average fullness of stomachs was essentially higher in perch (app. 60% in perch vs. 30% in herring). That may indicate that the feeding strategy of perch and herring larvae might be somewhat different: the perch larvae tend to be more opportunistic with respect to prey that herring larvae whose prey composition largely depends on prey size, i.e. adult feeding strategy seem to develop already in early life stages. The temporally shorter dependence on spatially patchy and highly versatile prey as copepod nauplii may provide perch larvae the advantage in larval food competition

description: We model X-ray reflection from white dwarfs (WD) in magnetic cataclysmic variables (mCVs) with a Monte Carlo simulation. A point source with a power-law spectrum or a realistic post-shock accretion column (PSAC) source irradiates a cool and spherical WD. The PSAC source emits thermal spectra of various temperatures stratified along the column according to the PSAC model. In the point source simulation, we confirm (1) a source harder and nearer to the WD enhances the reflection, (2) higher iron abundance enhances the equivalent widths (EWs) of fluorescent iron K$α_{1,2}$ lines and their Compton shoulder, and increases cut-off energy of a Compton hump, and (3) significant reflection appears from an area that is more than 90 deg apart from the position right under the point X-ray source because of the WD curvature. The PSAC simulation reveals that (1) a more massive WD basically enhances the intensities of the fluorescent iron K$α_{1,2}$ lines and the Compton hump, except for some specific accretion rate, because the more massive WD makes the hotter PSAC from which higher energy X-rays are preferentially emitted, (2) a larger specific accretion rate monotonically enhances the reflection because it makes the hotter and shorter PSAC, and (3) the intrinsic thermal component hardens by occultation of the cool base of the PSAC by the WD. We quantitatively evaluate influences of the parameters on the EWs and the Compton hump with both types of sources. We also calculate X-ray modulation profiles brought about by the WD spin. They depend on angles of the spin axis from the line of sight and from the PSAC, and whether the two PSACs can be seen. The reflection spectral model and the modulation model involve the fluorescent lines and the Compton hump and can directly be compared to the data which allow us to evaluate these geometrical parameters with unprecedented accuracy.

description: Grid environments have recently been developed with low stretch and overheads that increase with the logarithm of the number of nodes in the system. Getting and sending data to/from a large numbers of nodes is gaining importance due to an increasing number of independent data providers and the heterogeneity of the network/Grid. One of the key challenges is to achieve a balance between low bandwidth consumption and good reliability. In this paper we present an implementation of a reliable multicast protocol over a fault tolerant MPI: MPICHV2. It can provide one way to solve the problem of transferring large chunks of data between applications running on a grid with limited network links. We first show that we can achieve similar performance as the MPICH-P4 implementation by using multicast with data compression in a cluster. Next, we provide a theoretical cluster organization and GRID network architecture to harness the performance provided by using multicast. Finally, we present the conclusion and future work.

description: No abstracts are to be cited without prior reference to the author.The Vistula Lagoon plays a very important role as a spawning ground for herring (Clupea harengus) in the southern Baltic Sea. First-feeding herring larvae depend on rotifers, Eurytemora affinis nauplii, and younger copepodites. Subsequently, within two or three weeks, E. affinis copepodites 4-5 and adults become the main food for fast-growing larvae. During this time the mean biomass of food items increases rapidly. Then, during late spring, herring larvae start to feed on less favourable groups, e.g. rotifers, and the mean biomass of food items decreases; this is the consequence of considerable change in zooplankton composition, i.e. a decrease in larger copepod species and an increase in rotifers abundances. Chesson’s index was used to calculate larval prey selectivity. The change in preferences was particularly clear in the case of 1998; the first-feeding larvae searched for E. affinis copepodite stages 1-3 but very quickly switched to E. affinis older stages. Later in May, cladoceran Diaphanosoma brachyurum and Cyclopoida older stages also began to be selected positively. There were some differences in the relative importance of particular food items when the data from the two years were compared. Rotifers were the most important group for first-feeding larvae in 1998; by contrast, in 2004 the key role was played by copepod nauplii. After this short period, in both cases the most important food consisted of E. affinis copepodite stages 1-3 and especially E. affinis older stages. Later in May other groups started to be important as well: Diaphanosoma brachyurum and Cyclopoida older stages in 1998 and rotifers and Leptodora kindtii in 2004. The comparison of water temperatures recorded during the two years indicated that in 2004 herring experienced much more favourable conditions during egg incubation and the first-feeding periods (higher temperature and food availability). This resulted in extremely high hatching success and a high growth rate. However, such enormous abundances of predators caused considerable top-down pressure on prey organisms, which potentially led to starvation, slower growth rate, and high mortality.

description: The possibility of hybridizing collective electronic motion with mid-infrared (mid-IR) light to form surface polaritons has made van der Waals layered materials a versatile platform for extreme light confinement and tailored nanophotonics. Graphene and its heterostructures have attracted particular attention because the absence of an energy gap allows for plasmon polaritons to be continuously tuned. Here, we introduce black phosphorus (BP) as a promising new material in surface polaritonics that features key advantages for ultrafast switching. Unlike graphene, BP is a van der Waals bonded semiconductor, which enables high-contrast interband excitation of electron-hole pairs by ultrashort near-infrared (near-IR) pulses. We design a SiO$_2$/BP/SiO$_2$ heterostructure in which the surface phonon modes of the SiO$_2$ layers hybridize with surface plasmon modes in BP that can be activated by photo-induced interband excitation. Within the Reststrahlen band of SiO$_2$, the hybrid interface polariton assumes surface-phonon-like properties, with a well-defined frequency and momentum and excellent coherence. During the lifetime of the photogenerated electron-hole plasma, coherent polariton waves can be launched by a broadband mid-IR pulse coupled to the tip of a scattering-type scanning near-field optical microscopy (s-SNOM) setup. The scattered radiation allows us to trace the new hybrid mode in time, energy, and space. We find that the surface mode can be activated within ~50 fs and disappears within 5 ps, as the electron-hole pairs in BP recombine. The excellent switching contrast and switching speed, the coherence properties, and the constant wavelength of this transient mode make it a promising candidate for ultrafast nanophotonic devices.

description: No abstracts are to be cited without prior reference to the author.Long-term data on capelin feeding are used to study the dependence of capelin feeding on stock size and structure, distribution pattern and food supply in the cold (1976-1982) and warm (2001-2004) periods. Special attention is paid to size- and age-related features of capelin feeding associated with food abundance and availability, duration of feeding and food competition. It is shown that capelin prefer larger food objects which do not always dominate in plankton. It is concluded that capelin feed most efficiently (reaching up to 12-18% fatness) on the abundant, especially in warm years, food resources of the northern Barents Sea, including Arctic species of larger copepods (Calanus glacialis, Calanus hyperboreus) which are characterised by a high content of lipids.

description: We investigate the origin, the shape, the scatter, and the cosmic evolution in the observed relationship between specific angular momentum $j_\star$ and the stellar mass $M_\star$ in early-type (ETGs) and late-type galaxies (LTGs). Specifically, we exploit the observed star-formation efficiency and chemical abundance to infer the fraction $f_{\rm inf}$ of baryons that infall toward the central regions of galaxies where star formation can occur. We find $f_{\rm inf}\approx 1$ for LTGs and $\approx 0.4$ for ETGs with an uncertainty of about $0.25$ dex, consistent with a biased collapse. By comparing with the locally observed $j_\star$ vs. $M_\star$ relations for LTGs and ETGs we estimate the fraction $f_j$ of the initial specific angular momentum associated to the infalling gas that is retained in the stellar component: for LTGs we find $f_j\approx 1.11^{+0.75}_{-0.44}$, in line with the classic disc formation picture; for ETGs we infer $f_j\approx 0.64^{+0.20}_{-0.16}$, that can be traced back to a $z<1$ evolution via dry mergers. We also show that the observed scatter in the $j_{\star}$ vs. $M_{\star}$ relation for both galaxy types is mainly contributed by the intrinsic dispersion in the spin parameters of the host dark matter halo. The biased collapse plus mergers scenario implies that the specific angular momentum in the stellar components of ETG progenitors at $z\sim 2$ is already close to the local values, in pleasing agreement with observations. All in all, we argue such a behavior to be imprinted by nature and not nurtured substantially by the environment.

description: We present a new method to derive low-lying N-dimensional quantum wave functions by quadrature along a single trajectory. The N-dimensional Schroedinger equation is cast into a series of readily integrable first order ordinary differential equations. Our approach resembles the familiar W.K.B. approximation in one dimension, but is designed to explore the classically forbidden region and has a much wider applicability than W.K.B.. The method also provides a perturbation series expansion and the Green's functions of the wave equation in N-dimension, all by quadratures along a single trajectory. A number of examples are given for illustration, including a simple algorithm to evaluate the Stark effect in closed form to any finite order of the electric field.

Diffraction-free space-time beams

Publisher: name: arXiv
Year: 2017
Subjects: subject: Optics (physics.optics)

description: Diffraction-free optical beams propagate freely without change in shape and scale. Monochromatic beams that avoid diffractive spreading require two-dimensional transverse profiles, and there are no corresponding solutions for profiles restricted to one transverse dimension. Here, we demonstrate that the temporal degree of freedom can be exploited to efficiently synthesize one-dimensional pulsed optical sheets that propagate self-similarly in free space. By introducing programmable conical (hyperbolic, parabolic, or elliptical) spectral correlations between the beam's spatio-temporal degrees of freedom, a continuum of families of axially invariant pulsed localized beams is generated. The spectral loci of such beams are the reduced-dimensionality trajectories at the intersection of the light-cone with spatio-temporal spectral planes. Far from being exceptional, self-similar axial propagation is a generic feature of fields whose spatial and temporal degrees of freedom are tightly correlated. These one-dimensional `space-time' beams can be useful in optical sheet microscopy, nonlinear spectroscopy, and non-contact measurements.

description: We report the discovery of two well-defined tidal tails emerging from the sparse remote globular cluster Palomar 5. These tails stretch out symmetrically to both sides of the cluster in the direction of constant Galactic latitude and subtend an angle of 2.6 degrees on the sky. The tails have been detected in commissioning data of the Sloan Digital Sky Survey (SDSS), providing deep five-color photometry in a 2.5 degrees wide band along the equator. The stars in the tails make up a substantial part (~1/3) of the current total population of cluster stars in the magnitude interval 19.5 < i* < 22.0. This reveals that the cluster is subject to heavy mass loss. The orientation of the tails provides an important key for the determination of the cluster's Galactic orbit.

description: Following the previous paper in which quantum teleportation is rig orously discussed with coherent entangled states given by beam splittings, we further discuss two types of models, perfect teleportation model and non-perfect teleportation model, in general scheme. Then the difference among several models, i.e., the perfect models and the non-perfect models, is studied. Our teleportation models are constructed by means of coherent states in some Fock space with counting measures, so that our model can be treated in the frame of usual optical communication.

description: Grid computing has enabled pooling a very large number of heterogeneous resource administered by different security domains. Applications are dynamically deployed on the resources available at the time. Dynamic nature of the resources and applications requirements makes needs the grid middleware to support the ability of migrating a running application to a different resource. Especially, Grid applications are typically long running and thus stoping them and starting them from scratch is not a feasible option. This paper presents an overview of migration support in a java based grid middleware called DGET. Migration support in DGET includes multi-threaded migration and asynchronous migration as well.

description: This paper assesses the levels and trends in living standards across regions in Organisation for Economic Co-operation and Development (OECD) countries from the early 2000s to 2012. It applies a measure of welfare called multidimensional living standards (MDLS) at the regional level. The MDLS builds on the equivalent-income approach by combining monetary income with non-monetary (health and jobs) outcomes and taking into account how such outcomes are distributed amongst individuals. Results highlight that regional disparities are amplified when observed through an MDLS lens, as opposed to purely income-based regional disparities. The paper also shows that metropolitan residents experience, on average, higher levels of the MDLS and income than those in other regions.

Mon Révérend Père,

Je reçus jeudi dernier des mains du Père Salelles, prieur des augustins de cette ville, la planche de cuivre de l'honesta missio de Gordien Pie qu'il vous a plu de m'envoyer. Je l'ai vue avec toute la satisfaction possible. J'en aurai beaucoup de soin et elle vous sera retour (sic.) par une voie sûre. J'en connais tout le prix et la rareté. Je souhaite que ma santé qui n'est pas encore bien rétablie me permette de m'occuper de ce que vous désirez. Lorsque la personne à qui vous la confiâtes arriva ici, j'étais extrêmement malade et hors d'état de conférer de la moindre chose qui eut rapport à la littérature. Peu de jours après, on m'administra, un mois à peine a suffi pour me redonner des forces nécessaires pour me relever du fâcheux état où je me suis trouvé. Le Seigneur a bien voulu me conserver. Je me trouve mieux à présent. Je souhaite qu'elle me permette bientôt de revoir mes notes que je vous envoyais et en leur donnant plus d'étendueet vous marquez tout ce que je pense de ce précieux monument. Je l'avais presque perdu de vue. Je pensais que vous aviez pris le parti de l'envoyer à l'abbé du Ternay qui a des connaissances supérieures aux miennes. Il peut fixer mes doutes et les résoudre. Nous n'avons point ici de graveur capable de rendre l'originalité de cette planche, mais Monsieur d'Ennery en découvrira quelqu'un dans la capitale qui abonde en artistes de tout genre. Je ne vous en dis pas davantage. L'état où je me trouve s refuse à mon désir. Je suis & c.

SiO Maser Survey towards off-plane O-rich AGBs around the orbital plane of the Sagittarius Stellar Stream

description: We conducted an SiO maser survey towards 221 O-rich AGB stars with the aim of identifying maser emission associated with the Sagittarius stellar stream. In this survey, maser emission was detected in 44 targets, of which 35 were new detections. All of these masers are within 5 kpc of the Sun. We also compiled a Galactic SiO maser catalogue including ~2300 SiO masers from the literature. The distribution of these SiO masers give a scale height of 0.40 kpc, while 42 sources deviate from the Galactic plane by more than 1.2 kpc, half of which were found in this survey. Regarding SiO masers in the disc, we found both the rotational speeds and the velocity dispersions vary with the Galactic plane distance. Assuming Galactic rotational speed $Θ$0 = 240 km/s , we derived the velocity lags are 15 km/s and 55 km/s for disc and off-plane SiO masers respectively. Moreover, we identified three groups with significant peculiar motions (with 70% confidence). The most significant group is in the thick disc that might trace stream/peculiar motion of the Perseus arm. The other two groups are mainly made up of off-plane sources. The northern and southern off-plane sources were found to be moving at ~33 km/s and 54 km/s away from the Galactic plane, respectively. Causes of these peculiar motions are still unclear. For the two off-plane groups, we suspect they are thick disc stars whose kinematics affected by the Sgr stellar stream or very old Sgr stream debris.

ALMA and high redshift dusty starburst mergers

Year: 2000
Subjects: subject: Astrophysics (astro-ph)

description: By using a new numerical code for deriving the spectral energy distributions of galaxies, we have investigated the time evolution of morphological properties, the star formation rate, and the submillimeter flux at 850 $μ$m in high-redshift ($z$) dusty starburst mergers with mass ratio ($m_{2}$) of two disks ranging from 0.1 (minor merger) to 1.0 (major one). We found that the maximum star-formation rate, the degree of dust extinction, and the 850 $μ$m flux are larger for mergers with larger $m_{2}$. The 850 $μ$m flux from mergers at 1.5 $\le z \le$ 3.0 in the observer frame is found to be a few mJy for major merger cases, and at most $\sim$ 100 $μ$Jy for minor ones. This result suggests that only high-redshift major mergers are now detected by SCUBA with the current 850 $μm$ detection limit of a few mJy. These results imply that LMSA (ALMA) with the expected detection limit of the order of 10 $μ$Jy at 850 $μm$ can be used to study high-redshift mergers with variously different $m_2$, and thus provide an important clue to the formation of galaxies in a high-redshift universe.

description: No abstracts are to be cited without prior reference to the author.0-group herring was sampled in the Barents Sea in August-September 2002-2005 during the 0-group survey and trawl acoustic survey of pelagic fish, as well as during the trawl acoustic survey of demersal fish in November-December 2003. Diet of 0-group herring was found to consist of 28 food organisms of 9 phyla. The most frequently occurring food of juvenile herring in August-September were Copepoda, Cladocera, larvae of Bivalvia and Cirripedia, while adult and larval euphausiids and Calanus finmarchicus were predominant by weight. In November-December, juvenile herring fed mainly on adult euphausiids, pteropods and Metridia longa, but the portion of euphausiids by weight was the greatest. A dependence of food composition on fish length was revealed. C. finmarchicus dominated in the diet of herring smaller than 60 mm, while fish larger than 60 mm consumed mainly euphausiids. Prevalence of certain food in the diet of herring, in particular, of smaller fish, indicates the plankton species predominating in that period.

description: We study the local unitary equivalence for two and three-qubit mixed states by investigating the invariants under local unitary transformations. For two-qubit system, we prove that the determination of the local unitary equivalence of 2-qubits states only needs 14 or less invariants for arbitrary two-qubit states. Using the same method, we construct invariants for three-qubit mixed states. We prove that these invariants are sufficient to guarantee the LU equivalence of certain kind of three-qubit states. Also, we make a comparison with earlier works.
