title: Influence Of The Environment On The Sole (Solea Solea) Recruitment In The Kattegat. Preliminary Results
Creators: name: Nielsen, Else
Publisher: name: ASC 1997 - EE
Year: 2024
Subjects: Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.I-group sole abundance (yearclass index) along the Danish Kattegat coast is high in years where wind conditions are moderate during the larval development period (May-August) and low in years where wind conditions are strong. The relationship between wind conditions and recruitment is dome shaped. A significant correlation is also seen between nitrogen in the months where larval development takes place (July) and the yearclass index of I-group sole. These findings suggest that the wind may be food limited in years where the wind is too strong. This paper discusses the wind effect on sole, both the drift from the spawning grnund to the nursery ground, and the effect on nitrogen flux and primary production (sole food). We find that the abundance of I-group sole has increased significantly in the period 1960-1994. The associated increase in primary production appears to be related to the increase in sole recruitment. The I-group sole abundance data are derived from annual (1961-1994; 9 year missing)juvenile fish survey conducted by the Danish Institute for Fisheries Research.

description: No abstracts are to be cited without prior reference to the author.This paper investigates the effects of climatic variation on the distribution of North Seaherring along the shelf edge in the northeastern North Sea. Catch statistics and resultsfrom echo surveys show an unusual northern distribution of North Sea herring in thesummers of 1988-90. In these years the herring must have extended their northwardspring migration along the western slope of the Norwegian Trench. The summers of1988-90 were preceded by exceptionally mild winters. During winter, the herring isdistributed along the western edge of the Norwegian Trench. It can only maintain itsposition by steadily swimming against the inflowing Trench Current. It is speculated thathigh water temperatures during winter incite the herring to swim faster against thecurrent. This would result in a northern distribution in spring.

We prove that the extension is maximal, globally hyperbolic, and unique within a natural class of extensions. The key to those results is the proof that causal geodesics are either complete, or approach a singular boundary in finite affine time. Alternative maximal analytic extensions are also constructed.

The core-corona nanoparticles formed at pH = 3.00, were characterized. Their molecular weight and radius of gyration were determined by SLS, while their hydrodynamic radius was determined by dynamic light scattering. Small angle neutron scattering measurements were used to determine the radius of the insoluble complexes, comprising the core of the particles. The values obtained indicated that their size and aggregation number of the nanoparticles, were smaller when the content of the graft copolymers in neutral PDMAM side chains was higher. Such particles should be interesting drug delivery candidates, if the gastrointestinal tract was to be used.

description: No abstracts are to be cited without prior reference to the author.Observations obtained at standard sections and stations maintained by members of the ICES Oceanic Hydrography Working Group have been employed to examine present ocean climate conditions in the North Atlantic region. In the northwest Atlantic, increased air temperatures, reduced incidence of sea ice and warmer sea temperatures have been observed throughout the area since 1991-94. In Icelandic waters again moderate conditions have been experienced with relatively warm temperatures, despite generally lower salinities being observed. A moderating climate has also been observed in waters west of Greenland. Faroese standard sections have revealed that the freshening observed in water originating from the North Atlantic Current since the late 1980s has now stabilised.

description: Chemical gas sensors based on nanowires can find a wide range of applications in clinical assaying, environmental emission control, explosive detection, agricultural storage and shipping, and workplace hazard monitoring. Sensors in the forms of nanowires are expected to have significantly enhanced performance due to high surface-volume ratio and quasi-one-dimensional confinement in nanowires. Indeed, chemical gas sensors based on nanowires with a ppb level sensitivity have been demonstrated. In this review, the fundamental aspects on (i) methods of nanowire synthesis (ii) performance of nanowire sensors, (iii) chemiresistors, transistor sensors, and their sensing mechanism, and (iv) assembly technologies will be summarized and discussed. The prospects of the future research on chemical gas sensors based on nanowires will be also addressed.

description: The aim of this study is identification, isolation, structural characterization and qualification of degradation products DP-1, DP-2, DP-3 and DP-4. These impurities are major acid hydrolysis degradation products identified i n Osimertinib M esylate ( OSM) Tablets. T he O SM i s o bserved s table u nder thermal, photolytic and neutral conditions. The degradation of drug is observed under acidic, basic and oxidative conditions. Basic and oxidative degradation products already been reported, however, four novel degradation products are formed in acid hydrolysis which are not reported in the literature. Therefore, Using HPLC/PDA gradient program with waters X-bridge (250 mm × 4.6 mm, 5 µm) C18 column, the four acid hydrolysis degradants were identified and further characterized using UHPLC-IMS-QTOF-MS (ion mobility quadrupole time-of-flight m ass spectrometer) a nd N MR. T he s tructures o f D P-1, D P-2, D P-3 a nd D P-4 w ere further elucidated as hydroxy OSM Impurity, Des-acryl OSM impurity, Chloro OSM impurity and OSM dimer impurity, respectively. The structural characterization was followed by qualification of Impurities DP-1, DP-2, DP-3 and DP-4 using several different in-silico methodologies. From the results obtained, it can be concluded that no new structural alerts have been generated for DP-1 and DP-4 relative to the parent compound OSM. However, the degradation products, DP-2 and DP-3 shows structural alert positive for genotoxicity, which were both potential genotoxic substances. The current study presents separation, isolation, characterization and in-silico toxicity study for major acid degradants of OSM. The OSM generates DP-1 around 3.1%, DP-2 around 14.1%, DP-3 around 18.3% and DP-4 around 2.8% under acid hydrolysis on HPLC. The stress study was carried out in order to properly define the quality specifications for OSM drug products.

description: The increasing relevance of areas such as real-time and embedded systems, pervasive computing, hybrid systems control, and biological and social systems modeling is bringing a growing attention to the temporal aspects of computing, not only in the computer science domain, but also in more traditional fields of engineering. This article surveys various approaches to the formal modeling and analysis of the temporal features of computer-based systems, with a level of detail that is suitable also for non-specialists. In doing so, it provides a unifying framework, rather than just a comprehensive list of formalisms. The paper first lays out some key dimensions along which the various formalisms can be evaluated and compared. Then, a significant sample of formalisms for time modeling in computing are presented and discussed according to these dimensions. The adopted perspective is, to some extent, historical, going from "traditional" models and formalisms to more modern ones.

description: We present density functional calculations on the molecule based S=1/2 antiferromagnetic chain compound Cu PM(NO3)2 (H2O)2; PM = pyrimidine. The properties of the ferro- and antiferromagnetic state are investigated at the level of the local density approximation and with the hybrid functional B3LYP. Spin density maps illustrate the exchange path via the pyrimidine molecule which mediates the magnetism in the one-dimensional chain. The computed exchange coupling is antiferromagnetic and in reasonable agreement with the experiment. It is suggested that the antiferromagnetic coupling is due to the possibility of stronger delocalization of the charges on the nitrogen atoms, compared to the ferromagnetic case. In addition, computed isotropic and anisotropic hyperfine interaction parameters are compared with recent NMR experiments.

description: The ferromagnetic state of an Ising chain can represent a two-fold degenerate subspace or equivalently a logical qubit which is protected from excitations by an energy gap. We study a a braiding-like exchange operation through the movement of the state in the qubit subspace which resembles that of the localized edge modes in a Kitaev chain. The system consists of two Ising chains in a 1D geometry where the operation is simulated through the adiabatic time evolution of the ground state. The time evolution is implemented via the Suzuki-Trotter expansion on basic single- and two-qubit quantum gates using IBM's Aer QASM simulator. The fidelity of the system is investigated as a function of the evolution and system parameters to obtain optimum efficiency and accuracy for different system sizes. Various aspects of the implementation including the circuit depth, Trotterization error, and quantum gate errors pertaining to the Noisy Intermediate-Scale Quantum (NISQ) hardware are discussed as well. We show that the quantum gate errors, i.e. bit-flip, phase errors, are the dominating factor in determining the fidelity of the system as the Trotter error and the adiabatic condition are less restrictive even for modest values of Trotter time steps. We reach an optimum fidelity $>99\%$ on systems of up to $11$ sites per Ising chain and find that the most efficient implementation of a single braiding-like operation for a fidelity above $90\%$ requires a circuit depth of the order of $\sim 10^{3}$ restricting the individual gate errors to be less than $\sim 10^{-6}$ which is prohibited in current NISQ hardware.

description: A convenient methodology has been disclosed for the synthesis of 1,5-benzodiazepin-2-one and amino chromene-2-one analogues. The synthesized compounds act as biologically potent compared to 4-hydroxycoumarins. The reaction was carried out using 4-hydroxy coumarin and aniline derivatives containing both electron donating and electron withdrawing groups in toluene under reflux at 120°C. A library of compounds has been synthesized using different derivatives of aniline. The product formation has been achieved at stipulated time of 6 hours. The required compounds were obtained using column chromatographic technique and were characterized by 1HNMR, 13C-NMR and mass spectrometry. The products were obtained in high yield with good anticancer activity and significant antibacterial effects. Out of the synthesised derivatives, compound-2a, 2b, 4b, 4e, 4g, 4k displayed selective and potent cytotoxic effects against different cell lines as compared to that of parent compound. Among all the compounds, 4g and 4f were found to be highly active in inhibiting bacterial growth to the significant extent. Simple reaction procedure, better product yield and high biological activity are some outstanding features of the disclosed protocol.

Controlled redox potential microbiological leaching of chalcopyrite
Creators: name: Blancarte-Zurita, Martha Alicia
Publisher: name: University of British Columbia
Year: 2010

description: Leaching of chalcopyrite by Thiobacillus ferrooxidans under standard microbiological leaching conditions resulted in simultaneous solubilization of copper, iron and sulfur. The sulfide portion was oxidized preferentially over iron in solution suggesting a direct attack mechanism by the bacteria on the mineral particles. Copper extractions were low, 29-44%, with maximum specific copper extraction rates of the order of 0.001-0.006 h⁻¹ and cell yields per unit of copper released 4-43mg TOC/mg Cu. Leaching under redox-controlled conditions required a minimum pulp density, ca. 200 g/1, to result in elemental sulfur production. Some unknown factor, resulting from biological leaching activity under standard conditions and transferred with the liquid phase of the inoculum, was needed for the leach to occur under redox-controlled conditions. Copper extractions of 44-100% were achieved. Maximum specific copper extraction rates were of the order of 0.002-0.007 h⁻¹ with cell yield per unit of copper released of the order of 0.12-3.32mg TOC/g Cu for batch cultures. Ferrous iron in solution appeared to be the energy source for cell growth under redox-controlled conditions. The cells' sulfide oxidizing capacity seemed to be inhibited at the metabolic regulation level and not at the enzyme synthesis level. Cells growing under the standard conditions underwent a lag phase, upon transfer to the redox-controlled medium. During this lag phase low metal solubilization rates and low S⁰ production occurred, but when cell growth started, the leaching rates increased and the mineral dissolved rapidly. Electron diffraction X-ray analyses were carried out to investigate the role of silver in the controlled-redox leaching. No silver was observed to be on the surface of the chalcopyrite particles before or after the initial activation stage of the controlled-redox process. Silver deposits were observed after many hours of leaching. A mathematical model to describe the kinetics of microbial leaching, using a shrinking particle concept as its basis, was developed. When tested against data from the literature for leaching of Zinc from ZnS concentrate it was able to predict particle size as a function of leach time. It also gave reasonable predictions of particle size as a function of leach time for standard leaching of chalcopyrite but failed to predict accurate values for particle size as a function of leach time for the controlled-redox process.

Spectroscopic and photometric analysis of 21 chromospherically active variables: activity cycles and differential rotation

Year: 2021
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We investigate magnetic activity properties of 21 stars via medium resolution optical spectra and long-term photometry. Applying synthetic spectrum fitting method, we find that all targets are cool giant or sub-giant stars possessing overall [M/H] abundances between $0$ and $-0.5$. We find that six of these targets exhibit only linear trend in mean brightness while eight of them clearly shows cyclic mean brightness variation. Remaining seven target appear to exhibit cyclic mean brightness variation but this can not be confirmed due to the long time scales of the predicted cycle compared to the current time range of the photometric data. We further determine seasonal photometric periods and compute average photometric period of each target. Analysed sample in this study provides a quantitative representation of a positive linear correlation between the inverse of the rotation period and the cycle period normalized to the rotation period, on the log-log scale. We also observe no correlation between the activity cycle length and the relative surface shear, indicating that the activity cycle must be driven by a parameter rather than the differential rotation. Our analyses show that the relative surface shear is positively correlated with the rotation period and there is a noticeable separation between main sequence stars and our sample. Compared to our sample, the relative surface shear of a main sequence star is larger for a given rotation period. However, dependence of the relative surface shear on the rotation period appears stronger for our sample. Analysis of the current photometric data indicates that the photometric properties of the observed activity cycles in 8 targets seem dissimilar to the sunspot cycle.

description: In this note, we will discuss two aspects of brane-antibrane forces. In one aspect, we generalize the force calculation of D0-${\bar {\rm D}}$0 of Banks and Susskind to Dp-${\bar {\rm D}}p$ for $1\le p \leq 8$. In particular, we find that the force is also divergent for p = 1 while for the other cases ($p \ge 2$) the forces are in general finite when $Z \to 0^+$, where $Z = \frac{Y^2}{2π^2α'} - 1$ with Y, the brane-antibrane separation. However, the forces are divergent for all cases when Z < 0, signalling the occurrence of open string tachyon condensation in this regime. The other deals with the puzzling static nature of the supergravity brane-antibrane configurations. We will show that the force on a brane probe due to a brane-antibrane background vanishes when the probe is placed at the location of the coincident brane-antibranes, thereby providing a direct evidence for the existence of general static brane-antibrane configuration in the supergravity approximation.

The large number of data points in each of the BV(RI)_c bands and the ~0.01 magnitude accuracy of the individual measurements allow us a high precision analysis of the properties of the combination frequencies due to nonlinear coupling. Through the combination of the frequency spectra in different colors we show that except for the components corresponding to the linear combinations of the two pulsation modes, there are no other components present above the millimagnitude amplitude level.

description: This essay analyses a few references to the Punic Wars in the last months of the First World War and in the aftermath. Starting from a page from Hitler’s Mein Kampf, the exploitation of this historical analogy is traced in different types of texts by J.M. Keynes, H. Lloyd Jones, G. Stresemann and, finally, U. von Wilamowitz-Moellendorff. From the analysis of these sources, two lines of re-actualization of the Punic Wars emerge, one ‘liberal’ (Keynes and Lloyd Jones) and one nationalist (Wilamowitz, Hitler and, partially, Stresemann), which saw the Third Punic War as foreshadowing the ‘legend of the stab in the back’.

Sparse Spike Coding : applications of Neuroscience to the processing of natural images

Subjects: subject: Neurons and Cognition (q-bio.NC)

description: If modern computers are sometimes superior to humans in some specialized tasks such as playing chess or browsing a large database, they can't beat the efficiency of biological vision for such simple tasks as recognizing and following an object in a complex cluttered background. We present in this paper our attempt at outlining the dynamical, parallel and event-based representation for vision in the architecture of the central nervous system. We will illustrate this on static natural images by showing that in a signal matching framework, a L/LN (linear/non-linear) cascade may efficiently transform a sensory signal into a neural spiking signal and we will apply this framework to a model retina. However, this code gets redundant when using an over-complete basis as is necessary for modeling the primary visual cortex: we therefore optimize the efficiency cost by increasing the sparseness of the code. This is implemented by propagating and canceling redundant information using lateral interactions. We compare the efficiency of this representation in terms of compression as the reconstruction quality as a function of the coding length. This will correspond to a modification of the Matching Pursuit algorithm where the ArgMax function is optimized for competition, or Competition Optimized Matching Pursuit (COMP). We will in particular focus on bridging neuroscience and image processing and on the advantages of such an interdisciplinary approach.

description: In this work we study the issue of geodesic extendibility on complete and locally compact metric length spaces. We focus on the geometric structure of the space $(Σ(X),d_H)$ of compact balls endowed with the Hausdorff distance and give an explicit isometry between $(Σ(X),d_H)$ and the closed half-space $ X\times \mathbb{R}_{\ge 0}$ endowed with a taxicab metric. Among the applications we establish a group isometry between $\mbox{Iso} (X,d)$ and $\mbox{Iso} (Σ(X),d_H)$ when $(X,d)$ is a Hadamard space.

description: Spitzer observations of extended dust in two optically normal elliptical galaxies provide a new confirmation of buoyant feedback outflow in the hot gas atmospheres around these galaxies. AGN feedback energy is required to prevent wholesale cooling and star formation in these group-centered galaxies. In NGC 5044 we observe interstellar (presumably PAH) emission at 8 microns out to about 5 kpc. Both NGC 5044 and 4636 have extended 70 microns emission from cold dust exceeding that expected from stellar mass loss. The sputtering lifetime of this extended dust in the ~1keV interstellar gas, ~10^7 yrs, establishes the time when the dust first entered the hot gas. Evidently the extended dust originated in dusty disks or clouds, commonly observed in elliptical galaxy cores, that were disrupted, heated and buoyantly transported outward. The surviving central dust in NGC 5044 and 4636 has been disrupted into many small filaments. It is remarkable that the asymmetrically extended 8 micron emission in NGC 5044 is spatially coincident with Halpha+[NII] emission from warm gas. A calculation shows that dust-assisted cooling in buoyant hot gas moving out from the galactic core can cool within a few kpc in about ~10^7 yrs, explaining the optical line emission observed. The X-ray images of both galaxies are disturbed. All timescales for transient activity - restoration of equilibrium and buoyant transport in the hot gas, dynamics of surviving dust fragments, and dust sputtering - are consistent with a central release of feedback energy in both galaxies about 10^7 yrs ago.

Non posse suaviter vivi secundum Horatium: Bertolt Brecht e la propaganda augustea
Creators: name: Petorella, Fabrizio
Publisher: name: FuturoClassico FCl
Year: 2019
Subjects: Bertolt Brecht; Horace; First World War; Propaganda; Nazionalism; School

description: In a Bavarian Gymnasium, in an essay, a student harshly criticises a Horatian verse. It is not simply the outburst of a listless adolescent: it is 1916 and the young Bertolt Brecht, already author of poems imbued with nationalist rhetoric, can no longer tolerate the sententia according to which dulce et decorum est pro patria mori. After twenty centuries, the Augustan propaganda is still active, rearranged by the supporters of an intense patriotism. Calling into question Horace is a revolutionary act. However, this stance will not prevent Brecht from confronting himself with Horatian poetics. The Epicurean Horace remains an illustrious model, an emblem for that love for life which is at the core of many works of the German poet. This paper deals with the double fil rouge which links Brecht to Horace. In particular, It analyses the presence of Horatian echoes in the early works of the German poet, during the Great War and the immediately following years.

Un incubo di guerra, tra Virgilio e Pascoli: la chiusa del Pueri ludentes di Camillo Morelli (1915)
Creators: name: Luceri, Angelo
Publisher: name: FuturoClassico FCl
Year: 2019
Subjects: Camillo Morelli; Vergil; Giovanni Pascoli; Neo-Latin Poetry

description: Camillo Morelli (1885-1916), philologist and teacher of Latin Literature at the Military College of Rome, was poet and soldier, died fighting during the Great War. One of his Latin poems, the Pueri ludentes, written at the end of 1914 and awarded with the magna laus at the certamen Hoeufftianum 1915, shows Morelli’s skills in adapting the classical hexametric forms (especially of Vergil) to the representation of social and political passions of his age. Looking at Pa­scoli’s Latin Poetry as a model too, the writer reveals, especially in the final verses (vv. 182-217), the brutality of the conflict, showing a feeling of dislike and distrust towards Men, destined once again to succumb to their most violent instincts through the War.

The Deviation of the Broad-line Region Size Between Reverberation Mapping and Spectroastrometry

description: The combination of the linear size from reverberation mapping (RM) and the angular distance of the broad line region (BLR) from spectroastrometry (SA) in active galactic nuclei (AGNs) can be used to measure the Hubble constant $H_0$. Recently, Wang et al. (2020) successfully employed this approach and estimated $H_0$ from 3C 273. However, there may be a systematic deviation between the response-weighted radius (RM measurement) and luminosity-weighted radius (SA measurement), especially when different broad lines are adopted for size indicators (e.g., \hb\ for RM and \pa\ for SA). Here we evaluate the size deviations measured by six pairs of hydrogen lines (e.g., \hb, \ha\ and \pa) via the locally optimally emitting cloud (LOC) models of BLR. We find that the radius ratios $K$(=$R_{\rm SA}$/$R_{\rm RM}$) of the same line deviated systematically from 1 (0.85-0.88) with dispersions between 0.063-0.083. Surprisingly, the $K$ values from the \pa(SA)/\hb(RM) and \ha(SA)/\hb(RM) pairs not only are closest to 1 but also have considerably smaller uncertainty. Considering the current infrared interferometry technology, the \pa(SA)/\hb(RM) pair is the ideal choice for the low redshift objects in the SARM project. In the future, the \ha(SA)/\hb(RM) pair could be used for the high redshift luminous quasars. These theoretical estimations of the SA/RM radius pave the way for the future SARM measurements to further constrain the standard cosmological model.

description: With the possible detection of the fastest spinning nuclear-powered pulsar XTE J1739-285 of frequency 1122 Hz (0.8913 ms), it arouses us to constrain the mass and radius of its central compact object and to imply the stellar matter compositions: neutrons or quarks. Spun-up by the accreting materials to such a high rotating speed, the compact star should have either a small radius or short innermost stable circular orbit. By the empirical relation between the upper kHz quasi-periodic oscillation frequency and star spin frequency, a strong constraint on mass and radius is obtained as 1.51 solar masses and 10.9 km, which excludes most equations of states (EOSs) of normal neutrons and strongly hints the star promisingly to be a strange quark star. Furthermore, the star magnetic field is estimated to be about $4\times10^{7} (G) < B < 10^{9} (G) $, which reconciles with those of millisecond radio pulsars, revealing the clues of the evolution linkage of two types of astrophysical objects.

Individual schools were tracked for up to one hour.
Neutralization dynamics of slow highly charged ions passing through graphene nanoflakes--an embedding self-energy approach

description: We study the time-dependent neutralization of a slow highly charged ion that penetrates a hexagonal hollow-centred graphene nanoflake. To compute the ultrafast charge transfer dynamics, we apply an effective Hubbard nanocluster model and use the method of nonequilibrium Green functions (NEGF) in conjunction with an embedding self-energy scheme which allows one to follow the temporal changes of the number of electrons in the nanoflake. We perform extensive simulations of the charge transfer dynamics for a broad range of ion charge states and impact velocities. The results are used to put forward a simple semi-analytical model of the neutralization dynamics that is in very good agreement with transmission experiments, in which highly charged xenon ions pass through sheets of single-layer graphene.

description: No abstracts are to be cited without prior reference to the author.In July 1996 during an international echo-integrating survey in the southeastern North Sea, identification hauls were made in order to estimate the abundance of young herring. In additi­on, CTD profiles were taken for sound speed calibration purposes. Results show depth sepa­rated echoes to be either large quantities of young herring (mean length: 7.5 cm and 15 cm) or 0-group-cod (mean length: 5 cm). The occurrence of young herring was strictly concentrated to the warm upper layer (t > 12 °C) whereas young cod were exclusively found in the cold deeper layer (t < 8 °C).Juvenile herring was concentrated in an area where the vertically nearly homogeneous coastal water mixes with the stratified off-shore water masses, a zone of high plankton production. In order to identify the origin of the young cod concentrated in the cold waters, back calculations of the drift of this water mass were made by a hydro-dynamic model. Results show with high probability that during the cod spawning season a larger part of the water has been located at grounds in the southwestern North Sea.
