description: We discuss collective excitations of a trapped dilute Fermi gas within a hydrodynamic approximation. Analytical results are derived for both high- and low-temperature limits and are applied to $^{40}$K and $^6$Li systems of current experimental interest. We identify spectral signatures which can be used to detect the onset of Fermi degeneracy. Also, we find an interesting class of internal excitations with an unusual spectrum. Some of our results are relevant to the case of trapped bosons as well. Our analysis suggests several experiments which address fundamental problems of collective motion in quantum fluids.

description: No abstracts are to be cited without prior reference to the author.Ionic liquids are gaining attention as a new class of solvents in different chemical processes. Although their physical and chemical properties are promising for industry, however, because of their high stability and solubility in water, they can become persistent pollutants. The role of algae in aquatic environment is fundamental. In addition, primary producers are very sensitive to chemical compounds. In this study we investigated whether or not anions of imidazolium‐based ionic liquids have a toxic effect on algae strains. Three species were tested: a green alga (Chlorella vulgaris), a diatom (Skeletonema marinoi), and a cyanobacterium (Synechococcus sp.). Measurements of growth in different concentration of toxicants were made. The results demonstrate that all the analysed ionic liquids are toxic below 100 mg l–1. The EC50 values were estimated. The most sensitive were the diatom and cyanobacterium species. This indicates that the ionic liquids tested are potentially dangerous to aquatic organisms.

description: We calculate the cross section for $e^+ e^-$ annihilation into three jets for massive quarks at next-to-leading order in perturbative QCD, both on and off the $Z$ resonance. Our computation allows the implementation of any jet clustering algorithm. We give results for the three-jet cross section involving $b$ quarks for the JADE and Durham algorithm at c.m. energies $\sqrt s = m_Z$. We also discuss a three-jet observable that is sensitive to the mass of the $b$ quark.

description: No abstracts are to be cited without prior reference to the author.Experiments were carried out on three different picocyanobacterial strains from the genus Synechococcus: BA‐120, BA‐132, and BA‐124. The strains were isolated from the coastal part of the Gulf of Gdańsk (southern Baltic) and are maintained as unialgal cultures in the Culture Collection of Baltic Algae at the Institute of Oceanography in Gdynia (http://ocean.ug.edu.pl/~ccba/). The Synechococcus strains were exposed to light from different parts of the spectrum: red, green, blue, and white. To determine the capacity of the investigated strains for chromatic adaptation the concentration of photosynthetic pigments and photosynthetic activity were analysed. Chlorophyll a, carotenoid, and phycobilin concentrations were determined spectrophotometrically and the composition of carotenoids was analysed by HPLC. The measurements of photosynthesis rate were conducted using a Clark oxygen electrode, and chlorophyll fluorescence was measured using pulse amplitude modulation (PAM). Photosynthetic activity was characterized by the course of photosynthetic light–response curves (P–E), which produce the compensation (Pc) and saturation irradiances (Ek), the initial slope of photosynthetic curves (), maximum rate of photosynthesis (Pmax), and dark respiration (R). The values of the chosen fluorescence parameters were also analysed. Fv/Fm (maximum PSII quantum efficiency) and ΦPSII (effective PSII quantum efficiency) provide additional information concerning the photosynthetic apparatus. Each of the strains indicated the best growth and the best photosynthetic activity in full spectrum light. However, when different ranges of the light spectrum were compared, BA‐120 and BA‐132 (both phycoerythrin‐rich) strains exhibited favourable growth in green light, whereas for BA‐124 (phycocyanin‐rich) red light was better for growth.

description: In this work, we present a theoretical study for the collective oscillation modes, i.e. quadrupole, radial and axial mode, of a mixture of Bose and Fermi superfluids in the crossover from a Bardeen-Cooper-Schrieffer (BCS) superfluid to a molecular Bose-Einstein condensate (BEC) in harmonic trapping potentials with cylindrical symmetry of experimental interest. To this end, we start from the coupled superfluid hydrodynamic equations for the dynamics of Bose-Fermi superfluid mixtures and use the scaling theory that has been developed for a coupled system. The collective oscillation modes of Bose-Fermi superfluid mixtures are found to crucially depend on the overlap integrals of the spatial derivations of density profiles of the Bose and Fermi superfluids at equilibrium. We not only present the explicit expressions for the overlap density integrals, as well as the frequencies of the collective modes provided that the effective Bose-Fermi coupling is weak, but also test the valid regimes of the analytical approximations by numerical calculations in realistic experimental conditions. In the presence of a repulsive Bose-Fermi interaction, we find that the frequencies of the three collective modes of the Bose and Fermi superfluids are all upshifted, and the change speeds of the frequency shifts in the BCS-BEC crossover can characterize the different groundstate phases of the Bose-Fermi superfluid mixtures for different trap geometries.

description: We develop an microscopic model of the M-theory Schwarzschild black hole using the Banks-Fischler-Shenker-Susskind Matrix formulation of quantum gravity. The underlying dynamics is known to be chaotic, which allows us to use methods from Random Matrix Theory and non-equilibrium statistical mechanics to propose a coarse-grained bottom-up picture of the event horizon -- and the associated Hawking evaporation phenomenon. The analysis is possible due to a hierarchy between the various timescales at work. Event horizon physics is found to be non-local at the Planck scale, and we demonstrate how non-unitary physics and information loss arise from the process of averaging over the chaotic unitary dynamics. Most interestingly, we correlate the onset of non-unitarity with the emergence of spacetime geometry outside the horizon. We also write a mean field action for the evolution of qubits -- represented by polarization states of supergravity modes. This evolution is shown to have similarities to a recent toy model of black hole evaporation proposed by Osuga and Page -- a model aimed at developing a plausible no-firewall scenario.

description: We construct sequences of axially symmetric multisphaleron solutions in SU(2) Yang-Mills-dilaton theory. The sequences are labelled by a winding number $n>1$. For $n=1$ the known sequence of spherically symmetric sphaleron solutions is obtained. The solutions within each sequence are labelled by the number of nodes $k$ of the gauge field functions. The limiting solutions of the sequences correspond to abelian magnetic monopoles with $n$ units of charge and energy $E \propto n$.

description: Machine learning regression can predict macroscopic fault properties such as shear stress, friction, and time to failure using continuous records of fault zone acoustic emissions. Here we show that a similar approach is successful using event catalogs derived from the continuous data. Our methods are applicable to catalogs of arbitrary scale and magnitude of completeness. We investigate how machine learning regression from an event catalog of laboratory earthquakes performs as a function of the catalog magnitude of completeness. We find that strong model performance requires a sufficiently low magnitude of completeness, and below this magnitude of completeness model performance saturates.
title: Self-propulsion of Janus Particles near Polymer-Functionalized Substrates
Creators: name: Heidari, Mojdeh
Publisher: name: UNSPECIFIED
Year: 2021

description: This thesis presents the self-propulsion of Janus particles near the substrates functionalized with polymer brushes. The self-propulsion is based on self-thermophoresis which is a common mechanism to drive the autonomous motion of particles. Despite recent efforts to understand the mechanism governing the self-propulsion of thermophoretic particles, the interaction of particles with the substrate underneath the particle has remained unclear. However, the interfacial properties of the substrate/fluid interface might influence the interaction between the substrate and the particle, hence altering the particle velocity, orientation, etc. Therefore, it is crucial to achieve in-depth knowledge about the characteristics of the entire system to optimize the active motion of the particle.

description: The ultra-diffuse galaxy NGC1052-DF2 has a very low velocity dispersion, indicating that it has little or no dark matter. Here we report the discovery of a second galaxy in this class, residing in the same group. NGC1052-DF4 closely resembles NGC1052-DF2 in terms of its size, surface brightness, and morphology; has a similar distance of $D=19.9\pm 2.8$ Mpc; and also has a population of luminous globular clusters extending out to 7 kpc from the center of the galaxy. Accurate radial velocities of the diffuse galaxy light and seven of the globular clusters were obtained with the Low Resolution Imaging Spectrograph on the Keck I telescope. The velocity of the diffuse light is identical to the median velocity of the clusters, $v_{\rm sys}=\langle v_{\rm gc} \rangle=1445$ km/s, and close to the central velocity of the NGC1052 group. The rms spread of the observed velocities is very small at $σ_{\rm obs}=5.8$ km/s. Taking observational uncertainties into account we determine an intrinsic velocity dispersion of $σ_{\rm intr}=4.2^{+4.4}_{-2.2}$ km/s, consistent with the expected value from the stars alone ($σ_{\rm stars}\approx 7$ km/s) and lower than expected from a standard NFW halo ($σ_{\rm halo}\sim 30$ km/s). We conclude that NGC1052-DF2 is not an isolated case but that a class of such objects exists. The origin of these large, faint galaxies with an excess of luminous globular clusters and an apparent lack of dark matter is, at present, not understood.
description: ApJ Letters, in press. The revised version has a new figure and an expanded table with the sizes, axis ratios, and luminosities of the globular clusters. Thanks to an insightful comment of the referee it also includes a velocity measurement of the diffuse stellar light of the galaxy.

description: Distantly-supervised Relation Extraction (RE) methods train an extractor by automatically aligning relation instances in a Knowledge Base (KB) with unstructured text. In addition to relation instances, KBs often contain other relevant side information, such as aliases of relations (e.g., founded and co-founded are aliases for the relation founderOfCompany). RE models usually ignore such readily available side information. In this paper, we propose RESIDE, a distantly-supervised neural relation extraction method which utilizes additional side information from KBs for improved relation extraction. It uses entity type and relation alias information for imposing soft constraints while predicting relations. RESIDE employs Graph Convolution Networks (GCN) to encode syntactic information from text and improves performance even when limited side information is available. Through extensive experiments on benchmark datasets, we demonstrate RESIDE's effectiveness. We have made RESIDE's source code available to encourage reproducible research.

description: This paper presents a human-robot trust integrated task allocation and motion planning framework for multi-robot systems (MRS) in performing a set of tasks concurrently. A set of task specifications in parallel are conjuncted with MRS to synthesize a task allocation automaton. Each transition of the task allocation automaton is associated with the total trust value of human in corresponding robots. Here, the human-robot trust model is constructed with a dynamic Bayesian network (DBN) by considering individual robot performance, safety coefficient, human cognitive workload and overall evaluation of task allocation. Hence, a task allocation path with maximum encoded human-robot trust can be searched based on the current trust value of each robot in the task allocation automaton. Symbolic motion planning (SMP) is implemented for each robot after they obtain the sequence of actions. The task allocation path can be intermittently updated with this DBN based trust model. The overall strategy is demonstrated by a simulation with 5 robots and 3 parallel subtask automata.

description: In this paper, we investigate light bending in the spacetime of regular black holes with cosmic strings in weak field limits. To do so, we apply the Gauss-Bonnet theorem to the optical geometry of the black hole; and, using the Gibbons-Werner method, we obtain the deflection angle of light in the weak field limits which shows that the bending of light is a global and topological effect. Afterwards, we demonstrate the effect of a plasma medium on the deflection of light by RBCS. We discuss that increasing cosmic string parameter $μ$ and mass $M_0$ will increase the bending angle.

description: Double-peaked narrow emission lines in active galactic nucleus (AGN) spectra can be produced by AGN outflows, rotation, or dual AGNs, which are AGN pairs in ongoing galaxy mergers. Consequently, double-peaked narrow AGN emission lines are useful tracers of the coevolution of galaxies and their supermassive black holes, as driven by AGN feedback and AGN fueling. We investigate this concept further with follow-up optical longslit observations of a sample of 95 Sloan Digital Sky Survey (SDSS) galaxies that have double-peaked narrow AGN emission lines. Based on a kinematic analysis of the longslit spectra, we confirm previous work that finds that the majority of double-peaked narrow AGN emission lines are associated with outflows. We also find that eight of the galaxies have companion galaxies with line-of-sight velocity separations < 500 km/s and physical separations <30 kpc. Since we find evidence of AGNs in both galaxies, all eight of these systems are compelling dual AGN candidates. Galaxies with double-peaked narrow AGN emission lines occur in such galaxy mergers at least twice as often as typical active galaxies. Finally, we conclude that at least 3% of SDSS galaxies with double-peaked narrow AGN emission lines are found in galaxy mergers where both galaxies are resolved in SDSS imaging.

description: We present the abundances analysis for a sample of 11 red giant branch stars in the metal-poor globular cluster NGC 6809 based on high-resolution spectra. Our main goals are to characterize its chemical composition and analyze this cluster's behavior associated with the Multiple Population (MPs) phenomenon. In our work we obtained the stellar parameters and chemical abundances of 24 elements (O, Na, Mg, Al, Si, Ca, Ti, V, Cr, Mn, Fe, Co, Sc, Ni, Cu, Zn, Y, Zr, Ba, La, Ce, Eu, Nd and Dy). We found a radial velocity of 174.7 $\pm$ 3.2 km $s^{-1}$ and a mean iron content of [Fe/H]=-2.01 $\pm$ 0.02 in good agreement with other studies. Moreover, we found a large spread in the abundances of the light elements O, Na and Al confirming the presence of a Na-O anti-correlation a Na-Al correlation. The Mg-Al anti-correlation is also present in our cluster. The $α$ and iron-peak elements show good agreement with the halo field star trend. The heavy elements are dominated by the r-process.

description: Bioactive therapeutic molecules are generally impermeable to the cell membrane, hindering their utility and efficacy. A group of peptides called cell-penetrating peptides (CPPs) were found to have the capability of transporting different types of cargo molecules across the cell membrane. Here, we identified a short peptide named P2, which has a higher proportion of basic residues than the CDN1 (cyclin-dependent kinase inhibitor 1) protein it is derived from, and we used bioinformatic analysis and experimental validation to confirm the penetration property of peptide P2. We found that peptide P2 can efficiently enter different cell lines in a concentration-dependent manner. The endocytosis pathway, especially receptor-related endocytosis, may be involved in the process of P2 penetration. Our data also showed that peptide P2 is safe in cultured cell lines and red blood cells. Lastly, peptide P2 can efficiently deliver self-labeling protein HaloTag into cells for imaging. Our study illustrates that peptide P2 is a promising imaging agent delivery vehicle for future applications.

description: No abstracts are to be cited without prior reference to the author.The Curonian Lagoon is the largest freshwater coastal lagoon in the Baltic Sea. Phytoplankton and zooplankton samples were taken every month from March till November at 5–6 stations in 20072010. To distinguish between live and dead organisms zooplankton samples were stained using aniline blue. Dead organisms have been found in populations of all dominating zooplankton species. Both during the period of mass development of harmful cyanobacteria and subsequently, in July–October 2008–2010, the percentage of dead organisms from abundance and biomass measurements of zooplankton increased 5–13 times (up to 8.3–19.4%) compared with the percentage of dead organisms in July–October 2007 (1.5–1.8%), when the biomass of cyanobacteria was very low. The sensitivity of zooplankton taxonomic groups to “blooms” of cyanobacteria and the influence of toxins (according to the increasing proportion of dead organisms in periods of mass developing cyanobacteria) increased in the following order: Cyclopoida→Calanoida→Rotifera→Cladocera. The lowest percentage of dead organisms was observed at the station in which organic pollution, eutrophication, and biomass of harmful cyanobacteria (especially Microcystis spp.) were at lower levels. One of the main possible reasons for the increasing proportion of dead organisms in the zooplankton is the influence of toxins from Microcystis spp. We obtained a significant correlation between the proportion of dead organisms in the zooplankton and the biomass of toxic Microcystis spp. (r = 0.62–0.81). Green algae can presumably compensate for the negative effect of cyanobacteria, because the correlation between the proportion of Chlorophyta in the total biomass of phytoplankton and the proportion of dead organisms in the zooplankton was negative (r = –0.51–0.60). Thus, the proportion of dead organisms in the zooplankton is a sensitive indicator to determine the influence of harmful algae.
The Gender of άνθρωπος: An Excercise in False Generics
Creators: name: Makri-Tsilipakou, Marianthi

Year: 1989

description: Greek has been described as a language which possesses grammatical gender that is a syntactic category which classifies nouns into three classes (masculine/feminine/neuter) for the sole purpose of agreement. As gender assignment is generally believed to be arbitrary, no direct correlation seems to hold between biological gender or sex and grammatical gender, with the exception of animates or more strictly humans since as a rule, males are referred to by masculine nouns and females by feminine nouns. Additionally, nouns marked for masculinity may be used generically, i.e. refer to both males and females, on the ground that the masculine is “semantically unmarked” when referring to persons. This paper looks into the use of “generic” άνθρωπος in real life situations i.e. in addressing and/or referencing real human beings rather than in grammar book representations, with the intent to reveal its true sexual identity which more often than not – in 80% of the cases examined as a matter of fact - bears the mark of maleness and so excludes women from their fair share in humanity.

description: After an introduction on Subject-prominent and Topic-prominent languages, two different cases of Greek After-Thought Topics (Tails) are presented: • when the rightmost full-fledged NP is a personal name and • when it is an adjective. In either cases the AT (rail) has to be co-referential - through case agreement - with one of the arguments of the preceding verbs. When the AT (Tail) is a personal name, it seems that it has to conform to some syntactically controlled rules and principles. However, when it is an adjective, the AT (Tail) displays more characteristically its pragmatically controlled functional role conforming to the sense of the preceding passage rather than to syntactically controlled rules or principles.

description: In the area of online communication, commerce and transactions, analyzing sentiment polarity of texts written in various natural languages has become crucial. While there have been a lot of contributions in resources and studies for the English language, "smaller" languages like Czech have not received much attention. In this survey, we explore the effectiveness of many existing machine learning algorithms for sentiment analysis of Czech Facebook posts and product reviews. We report the sets of optimal parameter values for each algorithm and the scores in both datasets. We finally observe that support vector machines are the best classifier and efforts to increase performance even more with bagging, boosting or voting ensemble schemes fail to do so.

description: No abstracts are to be cited without prior reference to the author.In this study, cyanobacteria structure and abundance in the Gulf of Gdańsk and the Baltic Proper were examined. The diversity of toxin‐producing Nodularia spumigena was determined based on the profile of peptides produced by the cyanobacterium. In addition, nodularin concentrations in water, seston, fish, and soft tissues of blue mussels were measured by LCMS/MS. The results of the studies conducted in 2008–2010 were compared with the data collected in previous years. Our studies revealed the presence of different N. spumigena chemotypes in the Baltic Sea. In general, in the past three years N. spumigena biomass has decreased. In the Baltic Proper its maximal value dropped from 1782.86 μg l–1 in 2008 to 160 μg l–1 in 2010. The biomass of Synechococcus spp. started to decline before the peak of N. spumigena development, which in turn was followed by the increase in nutrient concentrations. This observation is contradictory to earlier findings indicating a stimulatory effect of N‐fixing N. spumigena on picocyanobacterium growth. As a consequence of the lesser abundance of N. spumigena, nodularin concentrations in all analysed samples were also lower than in previous years. In phytoplankton samples from the Baltic Proper nodularin never exceeded 4 μg l–1. The concentration of the toxin in soft tissues of Mytilus edulis was correlated with N. spumigena biomass and during cyanobacteria bloom it reached a maximum value of ca. 150 ng g1 dry weight.

description: In this paper we argue that enough is now known about the processes of translation for such insights to become an integral part and openly recognized part of foreign language education and for translation theory to take its proper place as major element in a broadly-based applied linguistics. It is further argued that both the two century-old paradigm of subjective, anecdotal and narrative evaluation of texts within which translation theory has operated and the century-old concentration on speech which has typified linguistics – both ‘pure’ and ‘applied’ – must both give way to a wider view of language as written text as well as spoken discourse; a view which must encompass, above all else, the study of translation. Specifically, the paper offers an initial model of the translation process; a sine qua non both for the development of an adequate theory of translation and for the application of insights from applied linguistics to translator training.

Publisher: name: arXiv

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: A sudden drop in mechanical friction, between an adsorbed nitrogen monolayer and a lead substrate, occurs when the lead passes through the superconducting transition temperature. We attribute this effect to a sudden drop at the superconducting transition temperature of the substrate Ohmic heating. The Ohmic heating is due to the electronic screening current that results from the sliding adsorbed film.

Is the Cabibbo-Kobayashi-Maskawa Matrix Symmetric at the GUT Scale?
Creators: name: Xing, Zhi-zhong
Publisher: name: arXiv
Year: 1997
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: By use of the one-loop renormalization group equations and current experimental data, we study the off-diagonal asymmetries of the Cabibbo-Kobayashi-Maskawa (CKM) matrix at the GUT scale in the framework of the standard model as well as its two Higgs and supersymmetric extensions. It is concluded that the possibility of a symmetric CKM matrix at the GUT scale has almost been ruled out.

On a New Conception of the Metrical Structure of Greece
Creators: name: Arvaniti, Amalia
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1989

description: Recent descriptions of the metrical structure of Greek postulate the existence of rhythmic stresses which are added at the surface level to preserve an even rhythm. No phonological evidence is presented in support of this claim and sometimes there is disagreement between the analyses about the location of the rhythmic stresses. It is claimed here that Greek does not exhibit rhythmic stress, a possible exception being cases that violate the Stress Well Formedness Condition (SWFC) of Greek i.e., words stressed on the (ante)penultimate followed by one or two clitics. For example, /simetoxitu/ his co-participants. Results of a perceptual experiment and acoustical analyses of natural speech support this claim as: (a) words like /simetoxitu/ his co-participants and /simetoxitu/ his participation, heard in segmentally identical contexts, are correctly disambiguated by Greek native speakers in 99.5% of the cases, although proponents of rhythmic stress claim that such pairs are metrically as well as segmentally identical and thus indistinguishable; (b) such word pairs are also acoustically distinct as far as the presence of stress on the host’s antepenult is concerned (/me/ in our example). It is concluded that Greek speakers do not impose stresses for purely rhythmic purposes; secondary stress is triggered only by the SWFC. Since Greek does not have rhythmic stress, it follows that, unlike English, it does not normally exhibit an even alternation of strong and weak syllables. It is suggested that Greek is best described metrically without reference to the foot level and using n-ary instead of binary branching. “Enclitic stress” is explained by the SWFC only. Clitics are metrically presented as forming compound Stress Groups with their host.

Local BRST cohomology in minimal D=4, N=1 supergravity
Creators: name: Brandt, Friedemann
Publisher: name: arXiv
Year: 1996
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The local BRST cohomology is computed in old and new minimal supergravity, including the coupling to Yang-Mills gauge multiplets. This covers the determination of all gauge invariant local actions for these models, the classification of all the possible counterterms that are invariant on-shell, of all candidate gauge anomalies, and of the possible nontrivial (continuous) deformations of the standard actions and gauge transformations. Among others it is proved that in old minimal supergravity the most general gauge invariant action can indeed be constructed from well-known superspace integrals, whereas in new minimal supergravity there are only a few additional (but important) contributions which cannot be constructed in this way without further ado. Furthermore the results indicate that supersymmetry itself is not anomalous in minimal supergravity and show that the gauge transformations are extremely stable under consistent deformations of the models. There is however an unusual deformation converting new into old minimal supergravity with local R-invariance which is reminiscent of a duality transformation.

Quantum computer with cold ions in the Aubry pinned phase

Publisher: name: arXiv

Subjects: subject: Quantum Physics (quant-ph)

description: It is proposed to modify the Cirac-Zoller proposal of quantum computer with cold ions in a global oscillator trap potential by adding a periodic potential with an incommensurate average ratio of number of ions to number of periods being order of unity. With the increase of the periodic potential amplitude the system enters in the Aubry pinned phase characterized by quasi-frozen positions of ions and a gap of their first phonon excitations becomes independent of number of ions. This gives hopes that this quantum computer will be really scalable. It is argued that the usual single- and two-qubit gates can be realized between the nearby ions in the Aubry phase. The possibilities of experimental realizations of a periodic potential with microtrap arrays or optical lattices are discussed. It is pointed that the disorder of distances between microtraps with one ion per trap can lead to the Anderson localization of phonon modes with interesting possibilities for ion quantum computing.

Factors Influencing the Interpretation of the Present Perfect and Past Tense Opposition
Creators: name: Psaltou-Joycey, Angeliki
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1989

description: The treatment of the present perfect and its contrast with the past tense in English has been one of the most problematic areas of linguistic analysis. In this paper I discuss the opposition of the two verb forms in some environments in which particular linguistic and contextual elements are present and the role these elements play in the interpretation of the situation and the choice between present perfect and past tense. I also examine briefly whether or not similar co-occurrence restrictions apply to the Modern Greek respective verb forms and, if not, what alternative linguistic forms are used for the interpretation of such situations.

Pressures, impacts, conservation, and management

description: No abstracts are to be cited without prior reference to the author.A catastrophic flood event occurred in the Vistula River catchment area in spring 2010. The flood water discharged in several crests into the Gulf of Gdañsk in late May and June. The impact of the flood on the environment of the Gulf of Gdañsk was scrutinized to a very limited extent in the routine monitoring activities of the Institute of Meteorology and Water Management (IMWM), but observations from the FerryBox system operating (since 2007) on a Stena Line ferry commuting daily between Gdynia (Poland) and Karlskrona (Sweden) provided a large amount of information on the response of the phytoplankton community to the additional supply of nutrients. The measurements carried out online by Blue Box revealed a rapid increase in seawater fluorescence/chlorophyll a around the beginning of June after the first flood crest discharged on 25 May. In addition to Blue Box autonomous measurements, discrete water samples were collected at predefined geographical locations along the ferry route. Discrete samples were subject to determination of various chemical (nutrients) and biological (chlorophyll a) constituents, including phytoplankton species structure (abundance and biomass) and algal toxins (hepatotoxins—nodularin, microcystin, and neurotoxins (BMMA and anatoxin‐a)). Community structure analyses revealed the presence of the potentially toxic species Aphanizomenon flos‐aquae, Nodularia spumigena, and Anabaena cf. torulosa, though the dominating phytoplankton group was non‐def. Unicell and regarding the species—Eutreptiella sp. (Euglenophyceae) within the Gulf of Gdañsk whereas diatoms, especially Chaetoceros simplex, were abundant in the offshore area along the ferry route. Nodularin concentrations of 0.1–0.2 μl l–1 were detected in the Gulf of Gdañsk on 8 and 22 June 2010.
