Subjects: aspectual features; inception; progressivity; termination; begin; start; continue; keep; stop; finish

description: The six verbs BEGIN/START, CONTINUE/KEEP and STOP/FINISH are among J. R. Firth's (1968 : 122) 'verbs of aspect' and can be described in terms of three aspectual features (Lyons (1977: 707): Inception (begin, start), Progressivity (continue, keep ) and Termination (stop, finish). The difference between begin and start is subtle, but a study of a number of features indicates that begin suggests initiation only, while start suggests initiation with progressivity. Both continue and keep indicate progressivity, but continue suggests progressivity with resumption (of a situation already in progress), while keep suggests progressivity with iteration. Similarly, stop and finish both indicate termination , but stop suggests termination at any point in a situation, while finish relates to termination with completion (of the situation). There is a brief consideration of three more marginal verbs: commence, cease and quit.

Subjects: Pressures, impacts, conservation, and management

description: No abstracts are to be cited without prior reference to the author.In the last decade changes in the hydrological regime have been seen in the Gdańsk Basin (Baltic Sea). The qualitative and quantitative characteristics of the bathymetric distribution of macrozoobenthos have been analysed at depths more than 61 m. The material was collected at 10 stations during 2001–2007 and treated by standard methods. In 2001–2007, 14 macrozoobenthic species (8–10 in each year) were found at depths of 61–70 m. Abundance and biomass were 6681691 individuals m–2 and 66–210 g m–2. Five species (4 in 2001–2003, 2–3 in 2004–2007) at depths of 71–80 m were observed. In 2001–2003, abundance was 230–498 individuals m–2 and in 2004–2007 it was 25–92 individuals m–2. Biomass also decreased from 29–82 g m–2 in 2001–2003, 29 g m–2 in 2004 to 1–2 g m–2 in 2005–2007. Macrozoobenthos was found at depths of 81–90 m only in 2002–2005. These were single specimens of Bylgides sarsi and juvenile Macoma balthica. In 2004, the polychaete Scoloplos armiger was found after a strong inflow in winter 2002–2003. Abundance and biomass were 2.5 individuals m–2 and <1 g m–2. Bylgides sarsi was detected at depths more than 91 m in some years (2003 and 2006). Our results agree with earlier data. Previously, at depths of 71–80 m there had been low species diversity of macrofauna, but with high abundance and biomass. It is shown that in 2003–2007 conditions for the existence and quantitative development of macrozoobenthos in the depth range 71–80 m worsened and on the other bathymetric ranges remained the same.

description: A kinetic Ising model is analyzed where spin variables correspond to lattice cells with mobile or immobile particles. Introducing additional restrictions for the flip processes according to the n-spin facilitated kinetic Ising model and using Monte Carlo methods we study the freezing process under the influence of an additional nearest-neighbor interaction. The stretched exponential decay of the auto-correlation function is observed and the exponent $γ$ as well as the relaxation time are determined depending on the activation energy $h$ and the short range coupling $J$. The magnetization corresponding to the density of immobile particles is found to be the controlling parameter for the dynamic evolution.

Composite Fermions and the Fractional Quantum Hall Effect: Essential Role of the Pseudopotential

Publisher: name: arXiv
Year: 1999
Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: The mean field (MF) composite Fermion (CF) picture successfully predicts the band of low lying angular momentum multiplets of fractional quantum Hall systems for any value of the magnetic field. This success cannot be attributed to a cancellation between Coulomb and Chern--Simons interactions between fluctuations beyond the mean field. It results instead from the short range behavior of the Coulomb pseudopotential in the lowest Landau level (LL). The class of pseudopotentials for which the MFCF picture is successful can be defined, and used to explain the success or failure of the picture in different cases (e.g. excited LL's, charged magneto-excitons, and Laughlin quasiparticles in a CF hierarchy picture).

The regular-irregular dissociation in non-native English past tense
Creators: name: Agathopoulou, Eleni
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2009
Subjects: Dual Mechanism; English past tense; second language acquisition

description: The present article investigates Pinker’s (1991) Dual Mechanism model in non-native (and native) morphology. Adult Greek learners and English natives produced the past tense of English pseudo-verbs varying in their similarity to existing verbs. Results seem problematic for Dual Mechanism and indicate no qualitative difference between L1 and L2 regarding the representation of regular/irregular morphology.

description: We present an analysis of extensive large-scale Monte Carlo simulations of self-avoiding fixed-connectivity membranes for sizes (number of faces) ranging from 512 to 17672 (triangular) plaquettes. Self-avoidance is implemented via impenetrable plaquettes. We simulate the impenetrable plaquette model in both three and four bulk dimensions. In both cases we find the membrane to be flat for all temperatures: the size exponent in three dimensions is nu=0.95(5) (Hausdorff dimension d_H=2.1(1)). The single flat phase appears, furthermore, to be equivalent to the large bending rigidity phase of non-self-avoiding fixed-connectivity membranes - the roughness exponent in three dimensions is xi=0.63(4). This suggests that there is a unique universality class for flat fixed-connectivity membranes without attractive interactions. Finally we address some theoretical and experimental implications of our work.

Restoration of abandoned wood pasture
Creators: name: Varga, Anna
Publisher: name: Zenodo
Year: 2017
Subjects: Wood pastures
Shrub clearing

description: Wood pastures with high nature and cultural value (HNCV) have been present in Hungary for thousands of years. Currently, there are 33 318 hectares of HNCV wood pasture in Hungary: 28 % is in protected areas and 60 % in EU Natura 2000.

In the 1950s, 88 % of productive land was wood pasture. Today, many HNCV wood pastures are now forested and overgrown with shrubbery and trees, causing serious problems at farm level.

The restoration of abandoned wood pastures is a key issue for developing the natural and cultural value of the rural region, and also for the profitability of the livestock industry. If areas are left abandoned they could be registered as forest areas, after which silvopastoral activity (grazing and/or pasture clearing) would be forbidden.

description: We study the discrete energy spectrum of curved graphene sheets in the presence of a magnetic field. The shifting of the Landau levels is determined for complex and realistic geometries of curved graphene sheets. The energy levels follow a similar square root dependence on the energy quantum number as for rippled and flat graphene sheets. The Landau levels are shifted towards lower energies proportionally to the average deformation and the effect is larger compared to a simple uni-axially rippled geometry. Furthermore, the resistivity of wrinkled graphene sheets is calculated for different average space curvatures and shown to obey a linear relation. The study is carried out with a quantum lattice Boltzmann method, solving the Dirac equation on curved manifolds.

On the Acquisition of Prepositions*

Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2009
Subjects: Acquisition of Ps; se; apo; complex Ps; locatives

description: This work studies the acquisition of Greek Prepositional Phrases. We focus on locative prepositions, because they may combine a lexical and a functional element, hence, can offer insights for both the acquisition and the syntactic status of prepositions from this perspective. We found that both, se and apo, appear after the lexical part of complex prepositions, and fully develop after age three. We compare se and apo when part of complex prepositions and when conveying location/direction alone and conclude that the former may be acquired after the latter. Apo is also encountered much earlier alone, but only preceding locative adverbials.

Subjects: Technologies and data
Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Harvesting the energy of waves and tides is still the subject of research and development as an increasing number of ingenious devices are invented and subjected to test. It is unclear which, if any, of these will ultimately be chosen for commercial deployment but the capacity for research and testing has expanded rapidly into an active multi‐million pound sector. Preparations for a commercial phase are underway in Scotland with the allocation of seabed leases to developers in the seas around Orkney; just in advance of Scotland’s first statutory marine spatial plan (MSP) which is under preparation in the area. Anxiety to build confidence in a new and nationally important industrial sector conflicts with a plethora of uncertainties about technology and impacts on the natural environment and existing uses. MSPs will help to build a new governance structure for marine space but in the Pentland Firth and Orkney (PFOW) waters area it is struggling to catch up with events. The EU FP7‐funded MESMA programme is designed to create a generic framework and tools for MSPs tested through nine case studies across Europe, including one in the PFOW which is led by ICIT/Heriot‐Watt University. This paper examines the PFOW case study and the gaps in knowledge which must be filled to build MSPs and the development of a balanced and sustainable marine energy industry.

description: A new proposal is given to achieve high degree of magnetoresistance (MR) in a magnetic quantum device where two magnetic layers are separated by a non-magnetic (NM) quasiperiodic layer that acts as a spacer. The NM spacer is chosen in the form of well-known Aubry-André or Harper (AAH) model which essentially gives the non-trivial features in MR due to its gaped spectrum and yields the opportunities of controlling MR selectively by tuning the AAH phase externally. We also explore the role of dephasing on magnetotransport to make the model more realistic. Finally, we illustrate the experimental possibilities of our proposed quantum system.

description: There have been limited studies to show what junior level language learners are taught and why. Just how useful are the words that Greek young learners of about 7 to 8 years old have acquired by the end of their first 'junior' year? The present paper presents a qualitative and quantitative analysis concerning the vocabulary used in a number of recent coursebooks for Junior A level. More specifically, the degree to which these words overlap with the first two thousand most frequent words in English is ascertained, according to wordlists from the General Service List (GSL) and the British National Corpus (BNC). In addition it reveals the topic areas within which the vocabulary of these coursebooks falls.

Element sets for high-order Poincaré mapping of perturbed Keplerian motion

description: The propagation and Poincaré mapping of perturbed Keplerian motion is a key topic in celestial mechanics and astrodynamics, e.g. to study the stability of orbits or design bounded relative trajectories. The high-order transfer map (HOTM) method enables efficient mapping of perturbed Keplerian orbits over many revolutions. For this, the method uses the high-order Taylor expansion of a Poincaré or stroboscopic map, which is accurate close to the expansion point. In this paper, we investigate the performance of the HOTM method using different element sets for building the high-order map. The element sets investigated are the classical orbital elements, modified equinoctial elements, Hill variables, cylindrical coordinates and Deprit's ideal elements. The performances of the different coordinate sets are tested by comparing the accuracy and efficiency of mapping low-Earth and highly-elliptical orbits perturbed by $J_2$ with numerical propagation. The accuracy of HOTM depends strongly on the choice of elements and type of orbit. A new set of elements is introduced that enables extremely accurate mapping of the state, even for high eccentricities and higher-order zonal perturbations. Finally, the high-order map is shown to be very useful for the determination and study of fixed points and centre manifolds of Poincaré maps.

Reading comprehension as a function of a reading-strategy program in monolingual and bilingual students with Special Educational Needs: An experimental study
Creators: name: Antoniou, Faye
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2009
Subjects: Special Educational Needs; bilingual; reading strategies; intervention

description: In order to find out if students with a different language background would benefit evenly by a reading-strategy program, 43 native speakers, 49 bilingual, and 55 second language speaking students from the 5th to 7th grade with Special Educational Needs were trained in strategic reading. A pre-, post- and follow-up design was conducted during one academic year assessing reading comprehension and reading strategy knowledge. Results indicated that students that spoke a second language at home and not the language of instruction, profited more from the reading-strategy program than the bilingual and native speakers.

description: No abstracts are to be cited without prior reference to the author.Marine Scotland Science (MSS) has been tasked with contributing to planning for the emerging wave and tidal energy industries by providing regional datasets from selected areas around Scotland. One aspect of the work was to survey the bathymetry of the west of Lewis, which represents one of the best wave resource areas in the UK. Bathymetric data were collected using the FRV “Scotia” with a Reson Seabat 7125‐B multibeam echosounder system. Transect lines were spaced so as to ensure greater than 50% overlap of adjacent swathes for the majority of the survey area. In total, 260 km2 of predominantly hard ground were surveyed to the west of Lewis from 21 July to 6 August 2010. The data were post‐processed using industry‐standard software. A quantitative approach was applied to make the best use of the bathymetric dataset. Within Arc GIS, the bathymetric data were used to create shape files with 5‐m depth intervals and 3° gradient intervals. A separate shapefile was created with buffer zones running parallel with the coastline, extending offshore at 1‐km intervals. Each of the layers created was classified, clipped to the same size, and brought together into one shapefile in a geodatabase. This allows the data to be queried according to the seabed depth, seabed gradient, and distance offshore. Areas of the seabed suitable for demonstration through to full‐scale commercial deployments of wave power converters can be calculated, based on developers’ operating tolerances for depth, gradient, and distance offshore.

description: We examine the models with gauge group U(1)^{k-1}\times\prod_{i=1}^k SU(n_i), which are obtained from decomposing the supersymmetry breaking model of Affleck, Dine and Seiberg containing an antisymmetric tensor field. We note that all of these models are distinct vacua of a single SU(N) gauge theory with an adjoint superfield. The dynamics of this model may be analyzed using the duality of Kutasov and Schwimmer and the deconfinement trick of Berkooz. This analysis leads to a simple picture for supersymmetry breaking for k=2, complementing that of previous work. We examine the flat directions of these models, and give straightforward criteria for lifting them, explaining the requisite peculiar form of the superpotential. For all cases with k>2, the duality argument fails to give supersymmetry breaking dynamics, and we identify a class of problematic flat directions, which we term 2m-baryons. We study in some detail the requirements for lifting these directions, and uncover some surprising facts regarding the relationship between R-symmetry and supersymmetry breaking in models with several gauge groups.

We applied control criteria to four dialogues and identified 3 levels of discourse structure. We investigated the mechanism for changing control between these structures and found that utterance type and not cue words predicted shifts of control. Participants used certain types of signals when discourse goals were proceeding successfully but resorted to interruptions when they were not.

Subjects: question production; subextraction; extraction site; negation; copying

description: The aim of this paper is to examine Greek preschool-age children's production of questions. Studies in other early languages reveal four common deviation patterns: wh-subextraction, avoidance of wh-object extraction, non-target performance on negative questions, and wh-copying/ partial movement. To assess Greek children' s performance, six 4-to-6 year old children participated in elicited production tasks. All deviation patterns in question were attested. The empirical findings of this study suggest that the further a wh-expression moves, the more difficult it is for children to process movement. Also, the child grammar produces representations that mirror LF representations when it comes to non-target question production.

description: Dynamic relaxation of the XY model and fully frustrated XY model quenched from an initial ordered state to the critical temperature or below is investigated with Monte Carlo methods. Universal power law scaling behaviour is observed. The dynamic critical exponent $z$ and the static exponent $η$ are extracted from the time-dependent Binder cumulant and magnetization. The results are competitive to those measured with traditional methods.
Exploring the development of Greek (non)temporal connectives with a Story Retelling Production Task
Creators: name: Papakonstantinou, Maria
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2016
Subjects: ambiguous, (non)temporal, connectives, verbal aspect, prime

description: The study aims to investigate the acquisition of the Greek connectives enό (=while/even though), kaθόs (=while/since) and afu (=after/since), which are ambiguous between a temporal and a non-temporal interpretation, and compare them with the unambiguous temporal όtan (=when). A short-story retell task (i.e. elicited production) was incorporated to answer our research aims. Four child groups aged 5;6, 7;8, 9;10 and 11;6 and a group of adult controls participated in the task. The results showed that the temporal interpretation of the ambiguous connectives is reproduced more than the non-temporal one. Unambiguous όtan is most frequently primed in the younger ages.

Exploiting the partitioning constancy/inconstancy of Membership Categorization Devices: Evidence from age categorization
Creators: name: Poulios, Apostolos
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2016
Subjects: ethnomethodology, conversation analysis, membership categorization device, age identity, partitioning constancy/inconstancy

description: This paper explores the usefulness of Harvey Sacks’s notions of partitioning constancy and inconstancy of membership categorization devices (MCDs) for the study of age identity construction. Partitioning constancy and inconstancy were shown by Sacks (1992a, b) to be two properties of MCDs that establish members’ co-membership or cross-membership with other members. The relevance of these properties for age categorization is shown through the analysis of conversational fragments in which middle-aged or older people either distance themselves from the categories old or older person and their negative attributes or endorse these categories and their positive characteristics.

description: No abstracts are to be cited without prior reference to the author.Marine Scotland Science (MSS) has been tasked with contributing to planning for the emerging wave and tidal energy industries by providing regional datasets from selected potential development areas around Scotland. Sustainable development must take into account seabed conservation interests. Inshore waters to the west of the Isle of Lewis contain one of the best wave resource areas in the UK and have not previously been surveyed using multibeam systems. Bathymetric data were collected using the FRV “Scotia” with a Reson Seabat 7125‐B multibeam echosounder system together with ground‐truthing data collected using a drop‐frame TV. In total, 260 km2 of predominantly hard ground were surveyed, 36 seabed TV tows were completed and over 600 digital stills were collected to the west of Lewis from 21 July to 6 August 2010. The bathymetry and backscatter data were post‐processed using industry‐standard software. An integrated approach was applied in which bathymetric, backscatter, and derived datasets were used to identify changes in the seabed facies. Subsequent ground‐truthing of the seabed facies using the footage from a drop‐frame TV allowed the compilation of a regional seabed habitat map leading to an assessment of the conservation interests in the area.

description: We present a wavefunction-based approach to correlated ab initio calculations on crystalline insulators of infinite extent. It uses the representation of the occupied and the unoccupied (virtual) single-particle states of the infinite solid in terms of Wannier functions. Electron correlation effects are evaluated by considering virtual excitations from a small region in and around the reference cell, keeping the electrons of the rest of the infinite crystal frozen at the Hartree-Fock level. The method is applied to study the ground state properties of the LiH crystal, and is shown to yield rapidly convergent results.

description: We investigate triatomic molecules that consist of two ground state atoms and a highly excited Rydberg atom, bound at large internuclear distances of thousands of Ångstroms. In the molecular state the Rydberg electron is in a superposition of high angular momentum states whose probability densities resemble the form of trilobite fossils. The associated potential energy landscape has an oscillatory shape and supports a rich variety of stable geometries with different bond angles and bond lengths. Based on an electronic structure investigation we analyze the molecular geometry systematically and develop a simple building principle that predicts the triatomic equilibrium configurations. %based on the properties of diatomic trilobite molecules. As a representative example we focus on $^{87}$Rb trimers correlated to the $n=30$ Rydberg state. Using an exact diagonalization scheme we determine and characterize localized vibrational states in these potential minima with energy spacings on the order of 100 MHz$\times h$.

description: Technology-based non-pharmacological interventions are a fast-growing area of dementia care and are being applied in a variety of care settings. Due to the readily available nature of many technology-based interventions which often have high face validity and are perceived to have very minimal side effects, research can lag behind clinical applications. Current research suggests that these interventions may be beneficial people to with dementia, but the extent of their effectiveness in specific aspects of dementia care and the impact on the wider care system is still being determined. A systematic review of the literature was conducted to review the effectiveness of technology based non-pharmacological interventions on stress and distress in dementia care settings. The term ‘stress and distress’ encompasses behaviour, affect, perception or thought disturbance symptoms in dementia, such as depression, anxiety, agitation, poor sleep and high levels of distress. While there is evidence that technology-based non-pharmacological interventions can be effective in reducing for stress and distress for people with dementia, the findings of the studies included in the review are mixed, meaning that there is not yet a clear indication of which, if any interventions are most effective. These results are discussed in relation to findings from other studies, with recommendations for future research and clinical applications. Current research on technology-based non-pharmacological interventions in dementia care often fails to consider staff as a significant factor in the application of interventions. A mixed method multiple-baseline single-case study methodology was used to assess the impact of the Tovertafel, a technology-based non-pharmacological intervention, on factors related to staff burnout in an acute dementia care ward. The Tovertafel (meaning Magic Table in Dutch) is a digital projection device which provides an interactive and playful recreation activity for people with dementia. The results suggested that the majority of participants demonstrated improvement in factors related to burnout, and a meta-analysis suggested small to medium effect sizes across participants. The thematic analysis of a qualitative staff experience questionnaire established three themes: patient’s positive engagement and response to the Tovertafel; benefits to staff from using the Tovertafel; and opportunities to enhance care with no changes to the normal workload. These results suggest that the Tovertafel may have the potential to improve staff outcomes in relation to burnout factors. Potential directions for future research are discussed.

description: We investigate the clustering properties of radio sources in the Alternative Data Release 1 of the TIFR GMRT Sky Survey (TGSS), focusing on large angular scales, where previous analyses have detected a large clustering signal. After appropriate data selection, the TGSS sample we use contains ~110,000 sources selected at 150 MHz over ~70% of the sky. The survey footprint is largely superimposed on that of the NRAO VLA Sky Survey (NVSS) with the majority of TGSS sources having a counterpart in the NVSS sample. These characteristics make TGSS suitable for large-scale clustering analyses and facilitate the comparison with the results of previous studies. In this analysis we focus on the angular power spectrum, although the angular correlation function is also computed to quantify the contribution of multiple-component radio sources. We find that on large angular scales, corresponding to multipoles $2 \leq \ell \leq 30$, the amplitude of the TGSS angular power spectrum is significantly larger than that of the NVSS. We do not identify any observational systematic effects that may explain this mismatch. We have produced a number of physically motivated models for the TGSS angular power spectrum and found that all of them fail to match observations, even when taking into account observational and theoretical uncertainties. The same models provide a good fit to the angular spectrum of the NVSS sources. These results confirm the anomalous nature of the TGSS large-scale power, which has no obvious physical origin and seems to indicate that unknown systematic errors are present in the TGSS dataset.

Cost transparency for transformative agreements (or how to calculate equivalent APCs within the DEAL-Wiley agreement)
Creators: name: Broschinski, Christoph

Publisher: name: Zenodo
Year: 2019
Subjects: OpenAPC, DEAL-Wiley, cost transparency, hybrid journals, transformative agreements

description: So far, OpenAPC has recorded cost data on Open Access articles in gold OA and hybrid journals. In view of the complexity of cost models for institutions participating in transformation contracts and the scope of costs for institutions with high subscriptions and, in the future, for institutions with high publication volumes, the question arises as to how the institutional costs per OA article in hybrid journals can be reported transparently in the context of transformation contracts. In addition, transformation agreements with large publishers concern relevant quantities of journal articles. For example, the DEAL-Wiley treaty covers about 12% of the annual German publication output in scientific journals.
 As part of the DFG-funded "INTACT" project, OpenAPC has already gained experience in monitoring OA articles in hybrid journals from transformative contracts (Springer Compact). In the context of the current BMBF-funded project "Cost Transparency as a Contribution to Open Access Transformation - KOA", we would like to work together with the data-giving OpenAPC community in this workshop to develop a procedure for the recording and cost-transparent presentation of article-related costs from transformation contracts using the DEAL-Wiley contract as an example.

A no-scale-like Kähler potential, the superpotential, and the gauge kinetic function are obtained in this 4-dimensional $E_6\times E_8$ model. We also study the general phenomenological consequences of the resulting M-theory-inspired model, which may include very light gravitinos, axions and axinos.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.A wave energy test site is proposed for inshore waters off the west coast of County Mayo, Ireland. The test site has been selected for its high wave energy levels, due to full Atlantic exposure conditions. Some seabird data for the test site is available from past surveys of Irish waters. Detailed data are not available and baseline bird surveys as part of the environmental impact assessment began in 2009. Surveys at sea followed standard European Seabird at Sea survey methods. Eight surveys were completed between October 2009 and October 2010, excluding winter. A total of 8092 birds of 33 species were recorded. In March 2011 monitoring surveys began at the wave energy test site. The monitoring survey design has been adapted to detect the effects of wave energy‐related activities on bird densities within the immediate area surrounding each test berth. It is an experimental approach that uses test (berth) and control sites with pre‐ and postactivity monitoring. Because there are only two test berths, the ”treatment” sample size of any sampling design is limited to 2 in order to avoid pseudoreplication. This, coupled with natural variance in seabird numbers, means that the power to detect small differences in seabird densities will be rather limited. Large‐scale differences should, however, be detectable. The key challenge has been how to develop an effective sampling strategy within practical and budgetary limitations and for a novel development. Baseline survey work was financed by Tonne Energy Ltd.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.This paper deals with increasing marine environmental concerns stemming from existing and planned technical activities in the Baltic Sea. Some of these activities interfere with natural physical fields (such as acoustic, magnetic, salinity, temperature, etc.) as well as disturb different natural processes (such as natural coastal dynamics, sedimentation, migration patterns of mobile species, etc.). In order to illustrate this problem, the most recent large‐scale constructions in the Baltic Sea (Oeresund Bridge, SwePol Link power cable, Nord‐Sream pipeline, offshore wind farms, and coastal defence structures) were selected. Disturbances of natural physical fields and possible ecological consequences of such disturbances are analysed. Proposals related to necessary monitoring and research activities, as well as the mitigation measures, are presented.

description: The magnetic excitations of the square-lattice spin-1/2 antiferromagnet and high-Tc parent La2CuO4 are determined using high-resolution inelastic neutron scattering. Sharp spin waves with absolute intensities in agreement with theory including quantum corrections are found throughout the Brillouin zone. The observed dispersion relation shows evidence for substantial interactions beyond the nearest-neighbor Heisenberg term, which can be understood in terms of a cyclic or ring exchange due to the strong hybridization path around the Cu4O4 square plaquettes.
