description: The ongoing and rapidly accelerating integration of inverter-based resources (IBRs), such as solar panels, into power distribution systems has heightened the importance of computational tools that can be used to study the dynamics of such systems. IBRs use power electronics to interface the energy sources to the grid, thereby introducing faster dynamics than their electromechanical counterparts, which could lead to instabilities in distribution systems and microgrids. Hence, there is a need for conducting simulations of distribution systems containing large numbers of single- and three-phase inverters, which could be operating under either grid-following or grid-forming modes.
A key objective of this thesis is to derive detailed, high-fidelity models of inverters and their controls in the context of unbalanced distribution networks. In addition, a diesel synchronous generator model is derived, for the sake of completeness. The main contribution of this work is that these models are developed for use in a novel simulation toolbox called Dynamic Simulation Tool using a Sparse Tableau Approach in Python, DynaSTPy (pronounced dynasty). This thesis outlines how the components can be modeled in the sparse tableau framework as electrical networks with topology described using a node-branch incidence matrix. In addition, the thesis explains how controller dynamics and constraints can be handled within this framework. These models are tailored to seamlessly integrate into the DynaSTPy toolbox. The proposed approach can be readily extended to model other such components in the future.

description: We report on a class of gapped projected entangled pair states (PEPS) with non-trivial Euler topology motivated by recent progress in band geometry. In the non-interacting limit, these systems have optimal conditions relating to saturation of quantum geometrical bounds, allowing for parent Hamiltonians whose lowest bands are completely flat and which have the PEPS as unique ground states. Protected by crystalline symmetries, these states evade restrictions on capturing tenfold-way topological features with gapped PEPS. These PEPS thus form the first tensor network representative of a non-interacting, gapped two-dimensional topological phase, similar to the Kitaev chain in one dimension. Using unitary circuits, we then formulate interacting variants of these PEPS and corresponding gapped parent Hamiltonians. We reveal characteristic entanglement features shared between the free-fermionic and interacting states with Euler topology. Our results hence provide a rich platform of PEPS models that have, unexpectedly, a finite topological invariant, forming the basis for new spin liquids, quantum Hall physics, and quantum information pursuits.

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to examine how racial source cues influence public opinion on issues of racial equity. Respondents were randomly assigned to be presented with one of eight fictional statements from a New York Times article that varied by content (black men must take responsibility for blacks to get ahead in society vs. government must end discrimination for blacks to get ahead in society) and source (President Obama vs. Former President Bill Clinton vs. Former Secretary of State Colin Powell vs. anonymous). A total of 568 respondents participated. Respondents were asked to indicate their support of the statement and feelings of favorability/unfavourability toward President Obama, Former President Bill Clinton, Colin Powell, and the New York Times. All respondents were also asked to complete measures of racial bias. This allowed for comparison of statement support across conditions, respondent race, and levels of racial bias.

description: In order to assess the present biological state and to give some guidelines for the planned monitoring of Pihlajavesi, one of the most important habitats for the threatened endemic relict Saimaa ringed seal (Phoca hispida saimensis Nordq.), the main communities of phytoplankton, zooplankton and benthic invertebrates were described using multivariate statistical analyses. The composition of phytoplankton assemblages was mainly determined by the nutrient concentration and the colour of the water so that the phytoplankton community of a clear-water basin differed in this lake from those of the other basins. In contrast there were no such differences in zooplankton assemblages between the basins, but the distinct difference between the pelagic and littoral communities was evident. The water depth and related parameters, such as bottom quality, were the most important factors affecting on zoobenthic assemblages. Species composition changed gradually with increasing depth, the rate of the change being greatest in the littoral area. The following soft bottom communities were distinguished from the lake: vegetated littoral (1–3 m), sublittoral (3–10 m), upper profundal (10–20 m) and deep profundal communities. The deep profundal assemblage in the effluent-loaded basin differed from that in other basins to such an extent that it could be considered to form a distinct community of its own. Special features of the communities resulting from the high transparency of water are discussed.

Reissner-Nordström black holes surrounded by perfect fluid dark matter: testing the viability of weak gravity conjecture and weak cosmic censorship conjecture simultaneously

description: A possible violation of the weak gravity conjecture (WGC) by cosmic censorship is one of the major challenges in the field of general relativity. However, in this paper, we explore the possibility of reconciling the WGC and the WCCC by considering Reissner-Nordström (R-N) black holes embedded in perfect fluid dark matter (PFDM) in asymptotically flat spacetimes. These two conjectures are seemingly unrelated, but a recent proposal suggested that they are connected surprisingly. In particular, We argue a promising class of valid counterexamples to the WCCC in the four-dimensional Einstein-Maxwell theory, considering a charged black hole when WGC is present. We demonstrate that by imposing certain constraints on the parameters of the metric, the WGC and the WCCC can be compatible. Furthermore, we investigate the properties of the charged black hole in the presence of PFDM for $Q > M$ and present some intriguing figures to test the validity of the WGC and the WCCC simultaneously. When PFDM is absent ($γ=0$), the RN black hole either has two event horizons if $Q^2/M^2\leq 1$ or none if $Q^2/M^2> 1$. The second scenario results in a naked singularity, which contradicts the WCCC. But when PFDM is present ($γ\neq 0$), the RN black hole has event horizons with regard to Q and M. This implies that the singularity is always covered, and the WGC and the WCCC are fulfilled. Furthermore, we demonstrate that there is a critical value of $γ$, called $γ_{ext}$, that makes the RN black hole extremal when $γ=γ_{ext}$. In this situation, the black hole has an event horizon, and the WGC and the WCCC are still fulfilled. We infer that PFDM can make the WGC and the WCCC compatible with the RN black hole and that the WGC and the WCCC agree with each other when PFDM is present.

description: This paper presents an overview of the changes in ground-level ozone and vegetation exposure occurring in Finland, both as observed in the recent decade, and as estimated for the period 1900 to 2100. A trend analysis of ozone and total nitrate concentrations is carried out for the 1989–2001 period. Future and past concentrations are modelled based on chemistry-transport model simulations, the SRES (Special Report on Emissions Scenarios) scenarios of the Intergovernmental Panel on Climate Change and emission inventories. Measured summertime ozone shows no decreasing trend despite reported precursor emission reductions. In central Finland, AOT40 (accumulated exposure over a threshold of 40 ppb) over April–September is presently about 6300 ppb h and is estimated to decrease by 570 ppb h as a result of the agreed European emissions reductions by 2010. A similar but opposite change results from the enhanced biogenic emissions of volatile organic compounds due to increased temperatures by 2050. According to the SRES scenarios, the tropospheric background concentrations will increase considerably until about 2050. After this, exposures begin to decline in those scenarios which emphasise new technologies and environmental aspects (8100 ppb h by 2050 in the B1 scenario), but increase monotonically in the A scenarios driven by economic growth.

description: This paper briefly reviews the measurement of precipitation by radar, discusses factors affecting the accuracy of such measurements, and outlines how such factors may be dealt with to improve the quality of precipitation measurements by radar for the purposes of the Baltic Sea Experiment (BALTEX). Precipitation products from the BALTEX Radar Network (BALTRAD) are then briefly presented, along with descriptions of how their qualities are improved, as are some new results on their accuracies. Intelligent compositing of data from a heterogeneous network, combined with innovative quality control, is shown to give high quality high resolution information for monitoring relative precipitation variability simultaneously over land and sea in both time and space. Gauge adjustment of radar-derived accumulated precipitation is shown to efficiently minimize the radar data's bias with increasing distance, thus yielding quantitatively useful datasets for application by the BALTEX community.

description: Xylem diameters of living trees change diurnally. According to the cohesion-tension theory these changes result from changes in sapwood water content. A model based on the assumptions of that theory was used to predict diameter changes from the water vapour exchange in a boreal Scots pine forest. The total evapo-transpiration was measured with the eddy-covariance technique and the contribution of the understorey with open chambers together with the monitoring of the soil water content by the Time-Domain Reflectometry (TDR) method. Comparisons between measured and calculated xylem diameter changes are presented and discussed. The results reveal that diameter changes follow quite well the water vapour exchange in the cases when there was no rain.

description: Rates of Ca and Mg release by weathering were calculated for four soil profiles (Haplic Podzols) in a small forested catchment in eastern Finland (63°10´N, 30°43´E). Three of the profiles were developed on glacifluvial fine sand and one on till, and all derived from granodiorites. Soil weathering rates (mmolc m–2 a–1) were calculated using three methods: Zr depletion, Ca + Mg\temperature sum regression, and the PROFILE model. The first two methods give long-term average rates while the latter gives the current rate. According to the Zr depletion method, the weathering rate of Ca was 7–32 (mean = 19) and that of Mg, 3–16 (mean = 9). According to the regression method, the weathering rate of Ca was 14–19 (mean = 15) and that of Mg, 5–9 (mean = 7). The mean values using the PROFILE model were 10 (Ca) and 3 (Mg). Values were corrected for stone content. Catchment input-output budgets gave values of 18 (Ca) and 8 (Mg).

description: Transition-edge sensors (TESs) have found a wide range of applications in both space- and land-based astronomical photon measurement and are being used in the search for dark matter and neutrino mass measurements. A fundamental aspect of TES physics that has not been investigated is the sensitivity of TESs to strong DC electric fields (10kVm−1 and above). Understanding the resilience of TESs to DC electric fields is essential when considering their use as charged particle spectrometers, a field in which TESs could have an enormous impact. Techniques such as x-ray photoelectron spectroscopy produce a high number of low-energy electrons that are not of interest and can be screened from the detector using electrostatic deflection. The use of strong electric fields could also provide a mass-efficient route to prevent secondary electron measurements arising from cosmic radiation in space-based TES applications. Integrating electron optics into the TES membrane provides an elegant and compact means to control the interaction between charged particles and the sensor, whether by screening unwanted particles or enhancing the particle absorption efficiency but implementing such techniques requires understanding the sensitivity of the TES to the resulting electric fields. In this work, we applied a uniform DC electric field across a Mo/Au TES using a parallel pair of flat electrodes positioned above and below the TES. The electric field in the vicinity of the TES was enhanced by the presence of silicon backing plate directly beneath the TES. Using this arrangement, we were able to apply of electric fields up to 90kVm−1 across the TES. We observed no electric field sensitivity at any field strength demonstrating the capability to use TESs in environments of strong electric fields.

description: Interactions between organisms are mediated by an intricate network of physico-chemical substances and other organisms. Understanding the dynamics of mediators and how they shape the population spatial distribution is key to predict ecological outcomes and how they would be transformed by changes in environmental constraints. However, due to the inherent complexity involved, this task is often unfeasible, from the empirical and theoretical perspectives. In this paper, we make progress in addressing this central issue, creating a bridge that provides a two-way connection between the features of the ensemble of underlying mediators and the wrinkles in the population density induced by a landscape defect (or spatial perturbation). The bridge is constructed by applying the Feynman-Vernon decomposition, which disentangles the influences among the focal population and the mediators in a compact way. This is achieved though an interaction kernel, which effectively incorporates the mediators' degrees of freedom, explaining the emergence of nonlocal influence between individuals, an ad hoc assumption in modeling population dynamics. Concrete examples are worked out and reveal the complexity behind a possible top-down inference procedure.
Stable isotope analysis of chironomid larvae from some Finnish forest lakes indicates dietary contribution from biogenic methane
Creators: name: Jones, R. I.

Publisher: name: Boreal Environment Research Publishing Board
Year: 2004

description: Larval chironomids (mostly Chironomus tenuistylus) were collected from the sediments of five small forest lakes in southern Finland during summer 2002. Carbon and nitrogen isotope ratios of larvae were determined by isotope ratio mass spectrometry. Isotope ratio variability among 23 individuals from one lake was appreciable, with [ta13C showing a range spanning 1.6% and [ta15N values a range spanning 5.6%. Between the lakes, larvae showed considerable variation in [ta13C with values as low as –55%. [ta15N values were strongly correlated with [ta13C values. The 13C-depletion found in the benthic chironomid larvae correlated with that found previously in zooplankton from the same lakes. It is argued that the low [ta13C values are most likely attributable to incorporation of carbon from biogenic methane, and that methane production can therefore make an important contribution to benthic as well as to pelagic food webs in these small forest lakes.

Freshwater snail assemblages of semi-isolated brackish water bays on the Åland Islands, SW Finland
Creators: name: Carlsson, R.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2006

description: The aim of the study was to relate the distribution of freshwater snails in 21 semi-isolated bays (within a salinity range of 0.7–7.4 practical salinity units, PSU) to environmental variables of the Åland Islands, SW Finland. Altogether 16 species of freshwater snails were found when the bays were investigated by hand-picking and a rod sieve. Of these, six or seven species may be regarded as almost ubiquitous. The salinity limiting most freshwater snails is approximately 4–5 PSU. The marine snail Hydrobia ventrosa was found in only two of the bays. The highest number of snail species occurred in bays with large catchment areas, especially where there were freshwater lakes in the local area. The number of species increased with decreasing salinity (Spearman's [rho] = –0.513). The maximum number of species was found in a bay with almost freshwater-like conditions, inferring that tolerance to higher salinities in some species is restricted.

description: The introduction of generative artificial intelligence (GenAI) into educational practices has been transformative, yet it brings a crucial concern about the potential distortion of users' beliefs. Given the prevalence of GenAI among college students, examining the psychological mechanisms that lead to GenAI distortion from both technological factors and the individual's psychological processes is a critical priority. A mixed-methods approach is employed to test the proposed hypotheses. Study 1 (N = 10) revealed through qualitative analysis that GenAI's fluent outputs significantly engaged college students, eliciting positive emotional responses during an interaction. GenAI's tendency to conflate fact with fiction often led to presentations of unrealistic and exaggerated information, potentially distorting users' perceptions of reality-a phenomenon termed GenAI distortion. Following these insights, Study 2 (cross-sectional survey, N = 999) and Study 3 (experimental manipulation, N = 175) explored how GenAI fluency affects college students' GenAI distortion and examined the mediating effect of positive affect. The results indicated that GenAI fluency predicts GenAI distortion via the mediating role of positive affect. Our findings provide theoretical foundations and practical implications for understanding GenAI distortion among college students.

description: Aerosol formation and subsequent particle growth in the ambient air have been frequently observed at the boreal forest site (SMEAR II station), southern Finland. The EU funded project BIOFOR (Biogenic aerosol formation in the boreal forest) has focused on a) the determination of formation mechanisms of aerosol particles in the boreal forest site, and b) the verification of emissions of secondary organic aerosols from the boreal forest site, including the quantification of the amount of condensable vapours produced in photochemical reactions of biogenic volatile organic compounds (BVOC) leading to aerosol formation. Although the exact formation route for 3 nm particles is still unclear, the project results can be summarised as follows: (i) The most probable formation mechanism is ternary nucleation (water-sulphuric acid-ammonia) and the growth to observable sizes is mainly due to condensation of organic vapours. However, we do not have a direct proof of these phenomena, since it is impossible to determine the composition of 1 to 5-nm-size particles using the present state-of-art instrumentation; (ii) If nucleation takes place, it always occurs in cold-air advection in polar and Arctic air masses at low cloudiness, and the nucleation is closely connected to the onset of strong turbulence, convection, and entrainment in the morning-noon transition from a stable to an unstable stratified boundary layer; (iii) The emissions rates for several gaseous compounds have been verified. The model calculations showed that the amount of the condensable vapour needed for observed growth of aerosol particles is in the range 1–5 x 107 cm–3. The estimations for the vapour source rate are in the range 3–8 x 104 cm–3s–1.

Year: 2004

description: The aim of this article is to describe a model for evaluating Local Agenda 21 processes. The local level extension of Agenda 21, Local Agenda 21 (LA21), is a typical instrument for extensive governance. It is primarily a voluntary sustainability policy tool with a goal of activating existing local government and other local stakeholder organisations in order to meet the local level challenges for the local and global environment, and social and local economic conditions. It also aims to create new governance structures among political and non-political actors. In a European perspective, the introduction of LA21 to cities can be considered as a success-story, but these activities are not distributed equally in Europe. To compare these differences we use a quantitative database from 146 European cities, all of them active in a LA21 or similar policy process. The data presented here is collected within an international research project entitled \LASALA — Local authorities' self-assessment of local Agenda\, funded by European Commission, DG Research, 5th Framework Programme, 2000–2001.

description: A network of 30 ring-width chronologies of Scots pine (Pinus sylvestris L.) from various parts of the boreal forest belt in north Europe were calibrated against seasonal indices of the North Atlantic Oscillation (NAO). The northernmost pines, from the forest-limit region, proved to be sensitive to summertime variations of the NAO, while most southern pines respond to winter variations in the NAO index. Going from the north to the south, growth responses demonstrate that this drastic shift occurs directly south of the northern part of the boreal belt. The southern part of the pine network was used for building a transfer model of wintertime NAO between 1893 and 1981. Although the final model explains only one quarter of the variance of the predictand winter NAO index, the verification statistics show reasonable reconstruction skill. This preliminary work will complement the increasing number of proxy experimental reconstructions of the NAO.

description: A fluorometer and multispectral underwater photodetector was used in different parts of Lake Ladoga during a joint Russian-Finnish expedition in 1995 to measure in vivo fluorescence and the intensity of solar and sky radiation. The spectral distribution of radiation at various depths in the water column and penetration of photosynthetically active radiation (PAR) were measured using an underwater multispectral photodetector (420–670 nm). The results were compared with Secchi disk and temperature measurements. The fluorometer values were highest in the pelagic zone of the lake and smallest in areas close to the Burnaya River and in the Volkhov Bay. Light absorption by algae and other suspended matter effectively reduced light penetration especially in the Volkhov Bay. Deepest transmission of light in water and relatively low fluorometer values were found in the western areas of the lake, where light (at 1% level of surface radiation) was transmitted more than six metres. Pulp mill waste waters seemed to decrease the photosynthetic activity in the NE part of the lake.

description: Peat dust emissions and particle concentrations at different distances from a milled peat production field were studied for two different harvesting methods. The dust emissions were found to be sporadic. The momentary PM2.5 concentrations, which varied up to 5 mg m–3 near the operation area, depended on the operation and weather conditions as well as peat composition. By using the Fugitive Dust Model, PM2.5 emission rates were estimated to range from 0.3 to 43 g s–1. Wind erosion increased the PM2.5 concentrations remarkably at wind speeds over 4 m s–1. Using time activity data of the different operational phases the lowest fine particle emissions were observed from the milling phase and the highest in the harvesting phases, respectively. As compared with the present EU daily limit value, the concentrations further from the peat production field were estimated to be low. However, short term negative influences on living conditions in the neighbourhood of peat production areas may be possible under certain environmental conditions.

description: The long-term, 1961–1990, mean summertime surface energy balance components in Finland were estimated by making use of earlier published studies for the estimation of the global radiation, surface albedo and latent heat flux. The net long-wave radiation was estimated with the help of synoptic cloud observations, and the sensible heat flux was calculated as the remainder in the energy balance equation. The results are presented both on a 10 km x 10 km grid and as climate-zone averages. The lowest values of global radiation, about 170 W m–2, were found in north-eastern Lapland. There was also a local minimum of about 190 W m–2 over the Suomenselkä divide and southern Ostrobothnia. The maximum values of about 220 W m–2 were found along the coast of the Baltic Sea. The cooling of the surface due to net long-wave radiation was smallest in northern Lapland, about –35 W m–2, elsewhere the spatial variation was very small, and the net long-wave radiation was from –40 to –45 W m–2. The highest values of evaporation occured in southern Finland, where the latent heat flux was about –80 W m–2, and the minimum in Lapland with a value of about –35 W m–2. The highest sensible heat fluxes were located along the coast and in Lapland, and the smallest in the inland areas of southern Finland. The difference in the sensible heat flux between the climate zones was small.

description: Organic nitrates (ON) are known to be present in secondary organic aerosol and act as a reservoir of nitrogen oxides, regulating the local and regional ozone and hydroxyl radical budgets. This work reports observations of particulate ON in Finnish remote boreal forest at a site with dominant emissions from biogenic volatile organic compounds. High Resolution-Aerosol Mass Spectrometer data were analysed in a unique way to characterize the sources of inorganic and organic nitrates. ON were found to be related to local sources with semi-volatile properties. Also they were implying a nocturnal formation mechanism. Occasionally, local sawmill emissions contributed greatly to the organic nitrates. The observations indicated that in the remote boreal forest area the NO3 radicals are oxidizing biogenic VOCs producing ON. This work demonstrates the significant impact of anthropogenic-biogenic emissions interaction on the atmospheric organic nitrate aerosol mass concentration.

description: Over the past few years, ionic conductors have gained a lot of attention given the possibility to implement them in various applications such as supercapacitors, batteries or fuel cells as well as for resistive memories. Especially, layered two-dimensional (2D) crystals such as h-BN, graphene oxide and MoSe2 have shown to provide unique properties originating from the specific 2D confinement of moving ions. Two important parameters are the ion conductivity and the chemical stability over a wide range of operating conditions. In this vein, Rb2Ti2O5 has been recently found displaying remarkable properties such as superionic conduction and colossal equivalent dielectric constant. Here, a first approach to the study of the electrical properties of layered Rb2Ti2O5 at the 100-nanometer scale is presented. Characterizations by means of micro-Raman spectroscopy and atomic force microscope (AFM) measurements of mechanically exfoliated RTO nanocrystals via the so-called adhesive-tape technique are reported. Finally, the results of electrical measurements performed on an exfoliated RTO nanocrystals are presented, and are found to be consistent with the results obtained on macroscopic crystals. 4

description: This paper presents a novel approach in wildfire prediction through the integration of multisource spatiotemporal data, including satellite data, and the application of deep learning techniques. Specifically, we utilize an ensemble model built on transfer learning algorithms to forecast wildfires. The key focus is on understanding the significance of weather sequences, human activities, and specific weather parameters in wildfire prediction. The study encounters challenges in acquiring real-time data for training the network, especially in Moroccan wildlands. The future work intends to develop a global model capable of processing multichannel, multidimensional, and unformatted data sources to enhance our understanding of the future entropy of surface tiles.
