Type locality.
“ Agricultural areas in Mueang Loei District, Loei Province, Thailand (17°34′43.020″N, 101°51′04.020″E) ”.
Differential diagnosis.
See under H. khaowongense.
Distribution.
This species is, apart from the type locality in Loei province, known from two more localities: one in Lampang and one in Chonburi province.
Remarks.
This species might be conspecific with H. khaowongense. The differences mentioned by Tanmuangpak and Dumrongrojwattana (2022) between this species and H. khaowongense (therein under Gyliotrachela saraburiensis) are only regarding the number of apertural barriers, which are very variable in H. khaowongense. We have noticed additionally that the shells of H. cultura are strongly shouldered when observed laterally (e. g., as in Tanmuangpak and Dumrongrojwattana 2022: Fig. 2 E, K) which is not typical for H. khaowongense. Due to the absence of relevant comparative material, we do not formally synonymise the two species. Specimens examined by us from Chonburi (Fig. 127) and Lampang provinces show very similar shell morphology as figured in Tanmuangpak and Dumrongrojwattana (2022), just with a wider umbilicus. We do not intend to describe this species as separate from H. cultura until more comparative material becomes available.

description: The relative importance of climate change, acidic deposition and forest harvesting/clearcutting on soil and streamwater chemistry of Rudbäcken, a small forested catchment in southern Finland, was evaluated by using a linked model system. The emphasis was on the assessment of long-term effects of different impact scenario combinations. The models were calibrated to measured values of soil and streamwater chemistry as well as forest biomass and growth increment. Deposition scenarios were based on atmospheric transport models. The effects of the three main driving forces (climate, deposition and forest harvesting) showed complex interactions, which were not always easy to interpret. Climate change (high change scenario), considerable emission reductions, and the clearcut scenario, were almost equally significant for parameters related to acidification effects. Considerable emission reductions resulted in either a slight improvement (streamwater pH) or steady-state (soil base saturation) compared with the current situation. The most negative response was predicted for the high climate change scenario, where high nitrogen immobilisation dependence on temperature was assumed. With the exception of the clearcut scenario, a clear increase in NO3 leaching in the long run was predicted for the site until the year 2050. Although the scenarios are hypothetical, they demonstrate the combined effects of elevated deposition inputs and climate change for the N leaching and accumulation processes.

description: We present the first step toward deriving cosmological constraints through the abundances of galaxy clusters selected in a $510\,\mathrm{deg}^2$ weak-lensing aperture mass map, constructed with the Year-Three shear catalog from the Hyper Suprime-Cam Subaru Strategic Program. We adopt a conservative source galaxy selection to construct a sample of $129$ weak-lensing peaks with a signal-to-noise ratio above $4.7$. We use semi-analytical injection simulations to derive the selection function and the mass--observable relation of our sample. These results take into account complicated uncertainties associated with weak-lensing measurements, such as the non-uniform survey depth and the complex survey geometry, projection effects from uncorrelated large-scale structures, and the intrinsic alignment of source galaxies. We also propose a novel modeling framework to make parts of the mass--observable relation insensitive to assumed cosmological parameters. Such a framework not only offers a great computational advantage to cosmological studies, but can also benefit future astrophysical studies using shear-selected clusters. Our results are an important step toward utilizing these cluster samples that are constructed nearly independent of any baryonic assumptions in upcoming deep-and-wide lensing surveys from the Vera Rubin Observatory, Euclid, and the Nancy Grace Roman Space Telescope.

description: In this paper Finnish fish market is described on the basis of the compiled official fisheries statistics and studies carried out by the Finnish Game and Fisheries Research Institute. The total fish consumption in Finland was about 320 000 tonnes in 1996, FIM 1 400 million in value. One half of the fish was used for human consumption and the other half as feed for fur animals. Baltic herring (Clupea harengus) and rainbow trout (Oncorynchus mykiss) are the most important species to Finnish consumers. In 1996, the Finns consumed 30.4 kg fish in ungutted weight per capita, of which these two species covered nearly one half. There are over 200 fish wholesale and processing companies in Finland, most of them are very small. In 1995, 30 000 tonnes of fish, mainly Baltic herring and rainbow trout, were used for processing. In 1992, there were some 250 specialized fish retail stores. However, nowadays the most important shopping places for fresh and processed fish are self-service shops and supermarkets.

Patterns of coherent dynamics within and between lake districts at local to intercontinental scales

description: Spatial patterns of coherent inter-annual dynamics between lakes occur within and between lake districts at regional, continental, and even intercontinental scales. Climatic variability and change are external drivers of lake dynamics but individual lake ecosystems differentially filter these signals and alter their expression. When related to landscape position spatial patterns in coherence can be uniform, unstructured, or structured. A structured pattern emerges for chemical responses to drought in a lake district dominated by groundwater while a more uniform pattern emerges in a stream-flow dominated lake district. Near-surface water temperatures and ice dates have a uniform pattern within and even between some lake districts; near-bottom water temperatures have an unstructured pattern; water levels have a complex pattern. Coherence in ice dates declines with latitudinal distance between lakes, but some coherence persists even at intercontinental scales that appears related to long-term climate change and common large-scale climate drivers.
Benthic diatom communities in Estonian rivers

Publisher: name: Boreal Environment Research Publishing Board
Year: 2001

description: Epilithic, epiphytic and epipelic (soft bottom) diatom communities were studied in three rivers (Ahja, Selja and Valgejõgi). Although the total number of recorded diatom taxa was 165, the studied diatom assemblages consisted of 32, 26, or 28 constant taxa in the three studied rivers, respectively. The dominating diatoms were Achnanthidium minutissimum, Cocconeis placentula, Amphora pediculus, Staurosirella pinnata, Planothidium lanceolatum, and Diatoma moniliformis. The cluster analysis of three different diatom communities yielded different results. The clustering of the composition and structure of the epilithic diatom community brought out three principal groups of river reaches differing in the trophic status of water. Hence the epilithic community of diatoms can be recommended for the monitoring of Estonian running waters.

description: Recently, multiple applications of machine learning have been introduced. They include various possibilities arising when image analysis methods are applied to, broadly understood, video streams. In this context, a novel tool, developed for academic educators to enhance the teaching process by automating, summarizing, and offering prompt feedback on conducting lectures, has been developed. The implemented prototype utilizes machine learning-based techniques to recognise selected didactic and behavioural teachers' features within lecture video recordings.
 Specifically, users (teachers) can upload their lecture videos, which are preprocessed and analysed using machine learning models. Next, users can view summaries of recognized didactic features through interactive charts and tables. Additionally, stored ML-based prediction results support comparisons between lectures based on their didactic content. In the developed application text-based models trained on lecture transcriptions, with enhancements to the transcription quality, by adopting an automatic speech recognition solution are applied. Furthermore, the system offers flexibility for (future) integration of new/additional machine-learning models and software modules for image and video analysis.

description: The interaction between waves and evolving media challenges traditional conservation laws. We experimentally investigate the behavior of elastic wave packets crossing a moving interface that separates two media with distinct propagation properties, observing the non-conservation of wavelength and frequency. Our experimental setup employs an elastic strip whose local stretching can be dynamically altered by pulling one end at a constant velocity. By demonstrating that this dynamic configuration creates a spatio-temporal interface traveling along the strip, we confirm theoretical predictions regarding observed shifts when a wave packet crosses this interface.

description: The concentrations, loads and speciation of rare earth elements (REEs) were studied in a 3.5 m thick mud depositional succession from an estuary in the Gulf of Bothnia. The uppermost 182.5 cm of the mud, estimated to have deposited from the early 1970s to 2011 (sampling year), had very high REE concentrations (596−1456 ppm) and accumulation rates (5.2−28 g m−2 year−1). This was explained by large REE export from acid sulfate soils after they became efficiently drained with modern drainage techniques. Geochemical and synchrotron-based spectroscopic (XANES) analyses showed that the REEs in the mud are relatively firmly bound in non-clastic phases, likely adsorbed by clay minerals and also to some extent by iron oxyhydroxides. Below 182.5 cm, the REE concentrations successively decreased down to background values at the base at 3.5 m, reflecting less efficient drainage and leaching of the acid sulfate soils in previous decades and centuries.

Natural factors influencing strontium concentrations in bulk and throughfall deposition, soil solution and litterfall in forest ecosystems on Olkiluoto Island, southwestern Finland

description: We studied the total concentrations of naturally occurring Sr in bulk deposition, stand throughfall, soil solution and litterfall in forest ecosystems located on Olkiluoto Island in southwestern Finland; in order to estimate the importance of sea water, soil chemical processes and plant and soil interactions on the Sr cycling in coastal areas of Baltic Sea. The area is specific because of the brackish sea water and land uplift from the sea. Bulk deposition samples were collected from two plots located in open areas and the other samples from four forest stands typical on Olkiluoto Island. The variation in the Sr concentrations in the stand throughfall and soil solution followed closely the variation in the base cations and anions. The highest individual Sr, base cation and anion concentrations were determined in the black alder-dominated forest stand close to the shore line of the Baltic Sea due to sea, high weathering input and nitrification. Nitrification on this plot led to nitrate leaching and increased buffering of acidity and weathering. All these processes promoted the presence of Sr in soil solution. Increased concentrations of naturally occurring Sr were reflected similarly in all sampled media, i.e., in stand throughfall, soil solution and litterfall.

description: Spatial distribution of brown trout (Salmo trutta) was studied on the Finnish coast of the northern Baltic Sea in 1998–2010 based on smolt tagging. The studied trout stocks were hatchery reared, and smolts were tagged with Carlin tags before release into the rivers. The distance between the release and recapture sites as well as location of the recapture site in relation to the release site (north, south, west, east) were analysed, taking the stock and sea age of the trout into account. The most important tag recovery areas at sea were the estuaries of the spawning rivers and coastal areas surrounding them. The natural direction of movement was along the coast line, north or south on the western coast and east or west in the Gulf of Finland. The release site and age affected migration direction. The distance of recoveries from the release sites varied for the same genetic stock released at different sites. The longest median recapture distances were recorded during the second sea year. The stocked brown trout (80%–95%) were mainly caught during their first two years in the sea before they become mature. Knowledge of spatial dispersal of sea trout is important for the management of the stocks and fisheries.

description: The geological and geomorphological settings of annually laminated sediments in Finnish boreal lakes in southern and central Finland were investigated. The purpose of the study was to identify the key sedimentary environmental factors of the morphometric features and catchment sediment types that control varve deposition in lakes. Altogether nearly 300 lakes were surveyed, of which 180 basins were cored. 35 of the cored lakes were found to contain partially laminated and 13 completely laminated sediments. Statistical analyses of the lake dataset, which also includes 15 previously located lakes composing varved sediments, show that two groups of lakes are more favourable for the formation of varves than others. The first group includes the majority of previously located varved lakes and is characterized by small-sized, relatively deep basins in glaciofluvial deposits. The second group is characterized by fairly equal proportions of till, bedrock and fine-grained sediment in the catchment, and it is more dependent on the shape of the catchment and basin itself than maximum depth and lake area. These lakes are located in the distal part of Younger Dryas end moraines or in the areas of ancient lake complexes or ice-lakes, and commonly comprise clastic-organic laminae couplets.
Should we further investigate the cascading effects of introduced fish on insectivorous birds?

description: We investigated whether the introduction of fish (brown trout, Salmo trutta) in previously fishless boreal lakes could alter the aquatic insect subsidy and affect the nesting population of insectivorous migratory birds, with a particular focus on the pied flycatcher, Ficedula hypoleuca, which is the most represented species. According to our paleolimnological data and bioenergetic model, introduced trout increased the adult midge biomass output from 18.6 to 28.7 kg (+54.6%), which was energetically significant and could have theoretically supported an increase in insectivorous birds nesting around the lake. While the long-term series of insectivorous birds nesting around the lake seemed to increase according to the modeled fish effects, we could not establish a clear link with changes in food availability. Our control (pied flycatchers) showed similar patterns as our treatment, suggesting that this species’ abundance was affected by factors other than fish presence in the lake. The demographic fluctuations and trends of the pied flycatcher at the regional scale seemed to override cascading effects linking introduced fish, emerging midges, and insectivorous birds. We conclude that further studies will be needed to investigate this topic and propose some areas for future research.

Year: 1999

description: An Arctic bottom ice algal community collected from a pack ice floe in the Greenland Sea in autumn 1995 was cultured at 10 salinities ranging from 4.0 to 90.8 PSU for 19 days. Growth of species was determined by microscopical analysis of samples taken every 3 to 5 days. During the experiment the abundance of the algae increased over a wide salinity range from 4.0 to 74.0 PSU, but decreased at the highest salinity (90.8). Maximum growth rates were 0.29 d–1 for the entire ice algal community and 0.42 d–1 for individual taxa. The final composition of the algal communities varied with salinities. Phytoflagellates and Chaetoceros spp. were most abundant at low salinities (<= 12.2), while pennate diatoms of the genus Nitzschia were the dominant algae at higher salinities.
Littoral oligochaete (Annelida: Oligochaeta) communities in neutral and acidic lakes in the Republic of Karelia, Russia
Creators: name: Ilyashuk, B.P.
Publisher: name: Boreal Environment Research Publishing Board
Year: 1999

description: The structure of littoral oligochaete communities in relation to pH was studied in five small lakes in South-western Karelia. Among the lakes, three were affected by acidification and characterized by low pH (mean pH = 4.2–5.9). Two lakes were neutral (mean pH = 6.9 and pH = 7.1, respectively). The oligochaete communities of the acidified lakes were poorer compared to the neutral ones. Taxa richness, total biomass of the oligochaetes, their relative density and relative biomass in macroinvertebrate communities were lower in the strongly acidified lakes. Changes of major taxon proportions in the total density and biomass of the oligochaetes were recorded with lowering of pH. For the analyses, the oligochaetes were separated into three functional feeding groups, as gatherers (S) that selectively ingest mainly on the sediment surface and other substrates, gatherers (T) that selectively ingest mainly in the sediments, and predators. Total density of gatherers (T) as well as their relative density in the oligochaete assemblage and macroinvertebrate communities were lower in the acidified lakes.

description: We present the design and validation of a variable temperature cryogenic blackbody source, hereinafter called a cold load, that will be used to characterize detectors to be deployed by CMB-S4, the next-generation ground-based cosmic microwave background (CMB) experiment. Although cold loads have been used for detector characterization by previous CMB experiments, this cold load has three novel design features: (1) the ability to operate from the 1 K stage of a dilution refrigerator (DR), (2) a 3He gas-gap heat switch to reduce cooling time, and (3) the ability to couple small external optical signals to measure detector optical time constants under low optical loading. The efficacy of this design was validated using a 150 GHz detector array previously deployed by the Spider experiment. Thermal tests showed that the cold load can be heated to temperatures required for characterizing CMB-S4's detectors without significantly impacting the temperatures of other cryogenic stages when mounted to the DR's 1 K stage. Additionally, optical tests demonstrated that external signals can be coupled to a detector array through the cold load without imparting a significant optical load on the detectors, which will enable measurements of the CMB-S4 detectors' optical time constants.

description: A regional coupled ocean-atmosphere-ice general circulation model for northern Europe is introduced for climate study purposes. The Baltic Sea is interactively coupled. The coupled model is validated in a 5-year hind-cast experiment with a focus on surface quantities and atmosphere-ocean heat fluxes. The coupled sea surface temperature matches observations well. The system is free of drift, does not need flux corrections and is suitable for multi-year climate runs. With flux forcing from the atmospheric model the regional ocean model gives sea surface temperatures statistically equivalent to the uncoupled ocean model forced by observations. Other oceanic surface quantities do not reach this quality in combination with the current atmosphere model. A strong dependence of sea ice extent on details of the atmospheric radiation scheme is found. Our standard scheme leads to an overestimation of ice, most likely due to a negative bias of long-wave radiation. There is indication that a latent heat flux bias in fall contributes to the ice problem. Other atmosphere-ocean heat fluxes are generally realistic in the long term mean.

Year: 1997

description: The ice pack is an important and highly sensitive component in the climatology of the Baltic Sea, which has been examined with a coupled ice-ocean model. The observed Baltic ice climate variability is well reproduced by the model. Future ice season are simulated as follows: in an average winter in 2050 ice is formed only in the Bay of Bothnia, the Archipelago Sea, the east of Gulf of Finland and on the Estonian west coast. The freezing date has been shifted about 20 days later and the break-up date 10 earlier. The ice thickness is 20 cm thinner. Locally such degrees of change could also be obtained using a simple analytic model. The coupled ice-ocean modeled 30 year’s ice statistics centered on 2050 gives a 30–65 cm range for the annual maximum ice thickness in the Bay of Bothnia. The length of the ice season varied from 3.5–6 months. The latest freezing occurred in January and the ice break-up happened at the earliest in April. Some ice would still be formed in 2100 at Kemi.

description: Trends in the frequencies, durations, mean and minimum sea level pressures, and cyclone formation point sea level pressures of relatively strong (mean sea level pressure < 1000 hPa) cyclones entering the Baltic Sea region between 1948 and 2010 were subject to analysis. Incoming cyclones were divided into ten clusters based on their formation points using the k-means clustering method. Changes in cyclone activity were compared with the North Atlantic Oscillation index. Although the incoming cyclone frequency did not change over the study period, over time the incoming cyclones became significantly stronger as they approached the region. There is no reason at present to assume that more cyclones have begun to form in some clusters. Only weak correlations were found between the number of incoming cyclones and the North Atlantic Oscillation index. Nevertheless, the overall tendency was for fewer but stronger incoming cyclones when the North Atlantic Oscillation index was positive.

Main upwelling regions in the Baltic Sea — a statistical analysis based on three-dimensional modelling

description: In the Baltic Sea upwelling is an important process, especially in the coastal areas, causing vertical mixing and displacement of the water body. During thermal stratification, when the surface layer of the water is depleted of nutrients, upwelling plays a key role in replenishing the euphotic zone with the nutritional components necessary for biological productivity. Up to now, only a few comprehensive investigations have been carried out to study the locations of the main upwelling areas in the Baltic and how commonly these upwellings take place. Here, three-dimensional high-resolution modelling is used as a tool to statistically estimate an index reflecting the persistency of upwellings (downwellings) in various parts of the Baltic. This estimate is made for the summer season over the ten-year period from 1979 to 1988. The new idea in this paper is to use the persistency (stability) of the vertical velocity to define an upwelling index, instead of calculating the frequency of upwelling on the basis of changes in the sea-surface temperature, as is usually done. The model results were compared with measurements of surface temperature and salinity in the Gulf of Finland in 1988, where several strong upwelling cases were observed. The fit between the model results and measurements was found to be good. The upwelling indexes were compared with corresponding upwelling frequencies in the Swedish coastal area based on an analysis of long-term sea-surface temperature measurements. The results, based on these two different approaches, correspond well with each other. Consequently, we can expect that the three-dimensional model can be used to good effect as a tool to describe the overall statistics of the main upwelling areas in the Baltic. The results of the ten-year simulation show that coastal-type upwellings (downwellings) dominate, with values of the index as high as 30%–50% (–30% to –50%), being typically between 10% and 30% (–10% to –30%). The width scale of upwellings (perpendicular to the coast) is typically only 5–20 km. The length scale is somewhat more variable, being typically between 30 and 150 km (alongshore).
Loop-induced masses for the first two generations with optimum flavour violation

description: A mechanism for the masses of third, second, and first generation charged fermions at the tree, 1-loop, and 2-loop levels, respectively, is proposed. The fermionic self-energy corrections that lead to this arrangement are induced through heavy vector bosons of a new gauged flavour symmetry group $G_F$. It is shown that a single Abelian group suffices as $G_F$. Moreover, the gauge charges are optimized to result in relatively smaller flavour violations in processes involving the first and second generation fermions. The scheme is explicitly implemented on the Standard Model fermions in an anomaly-free manner and is shown to be viable with observed charged fermion masses and quark mixings. Constraints from flavour violations dictate the lower limit on the new physics scale in these types of frameworks. Through optimal flavour violation, it is shown that nearly two orders of magnitude improvement can be achieved on the lower limit, leading to the new physics scale $\ge 10^3$ TeV in this case. Further improvements are possible at the cost of the down quark mass deviating more than $3 σ$ from its value extracted from lattice calculations. Options for inducing tiny masses for light neutrinos are also discussed.

Quantum noise induced nonreciprocity for single photon transport in parity-time symmetric systems

description: We show nonreciprocal light propagation for single-photon inputs due to quantum noise in coupled optical systems with gain and loss. We consider two parity-time ($\mathcal{PT}$) symmetric linear optical systems consisting of either two directly coupled resonators or two finite-length waveguides evanescently coupled in parallel. One resonator or waveguide is filled with an active gain medium and the other with a passive loss medium. The light propagation is reciprocal in such $\mathcal{PT}$ symmetric linear systems without quantum noise. We show here that light transmission becomes nonreciprocal when we include quantum noises in our modeling, which is essential for a proper physical description. The quantum nonreciprocity is especially pronounced in the $\mathcal{PT}$ broken phase. Transmitted light intensity in the waveguide of incidence is asymmetric for two waveguides even without noise. Quantum noise significantly enhances such asymmetry in the broken phase.

description: Climate change, as indicated by changes in air temperature, was simulated with the SILMU (the Finnish Research Programme on Climate Change) scenarios. The effects of air temperature change on the temperature regime of five lakes were studied with a temperature model using two approaches. The parameters describing the temperature regime were vertical temperature distribution, length of the stratification period, time of freezing and time of ice break-up. The surface areas of the lakes range from 0.25 km2 to 161 km2 and depths from 13 to 85 m. For one lake (Pääjärvi) the averages and the standard deviations of the temperature parameters in a changing climate were computed for the years 2036–2065. For the year 2050 (June-August) the surface temperature increases by 1.8deg.C, and the low and high estimates are 0.5deg.C and 2.6deg.C. For the other lakes a spatial approach was used. Representative values for air temperature in the years 2020, 2050 and 2090 were used to obtain a spatial description of the temperature regime of small lakes all over Finland. All the results showed significant changes in the temperature regime, e.g. changes of 30–60 days were predicted in the length of stratification and ice-covered period.
Environmental factors related to water level regulation — a comparative study in northern Finland
Creators: name: Hellsten, S.K.
Publisher: name: Boreal Environment Research Publishing Board
Year: 1997

description: The environmental conditions of the littoral zone were studied in the regulated Lake Ontojärvi and the unregulated Lake Lentua in northern Finland. The general aims of the study were to analyse the environmental factors related to water level regulation in the littoral zone and to produce information for assessing the effects of hydroelectric development in northern lakes. The study was basically carried out by comparing the littoral environments of the two study lakes. The most visible effects of water level regulation were related to the raised water level, which yielded erosion of sandy shores at the beginning of the regulation. Another effect of lake regulation was the altered fluctuation of the water level, which led to bottom instability and increased the size of the frozen and ice penetration zones. The effect of ice penetration was also easy to recognize on the shores of Lake Ontojärvi, where the surface sediment was frozen to a greater depth and across wider areas than in Lake Lentua. Below the freezing zone, the ice just pressed down on the sediment. The shores of Lake Ontojärvi were steeper than those of Lake Lentua, what affected the distribution of bottom types, with sandy bottoms being more common in Lake Lentua than in Lake Ontojärvi. The factors related to site exposure included effective fetch and the shape of the shoreline. The sedimentation level correlated only with the slope and was not predicted by the fetch or shape. The vertical reduction of light was estimated on the basis of water colour. The main environmental factors from the two lakes were used in a discriminant analysis to predict the bottom type distribution of the littoral (r2 = 0.41).
