description: The epithelial–mesenchymal transition (EMT) represents a pivotal frontier in oncology, playing a central role in the metastatic cascade of cancer—a leading global health challenge. This comprehensive review delves into the complexities of EMT, a process where cancer cells gain exceptional mobility, facilitating their invasion into distant organs and the establishment of secondary malignancies. We thoroughly examine the myriad of factors influencing EMT, encompassing transcription factors, signalling pathways, metabolic alterations, microRNAs, long non-coding RNAs, epigenetic changes, exosomal interactions and the intricate dynamics of the tumour microenvironment. Particularly, the review emphasises the advanced stages of EMT, crucial for the development of highly aggressive cancer phenotypes. During this phase, cancer cells penetrate the vascular barrier and exploit the bloodstream to propagate life-threatening metas-tases through the mesenchymal–epithelial transition. We also explore EM significant role in fostering tumour dormancy, senescence, the emergence of cancer stem cells and the formidable challenge of therapeutic resistance. Our review transcends a mere inventory of EMT-inducing elements; it critically assesses the current state of EMT-focused clinical trials, revealing both the hurdles and significant breakthroughs. Highlighting the potential of EMT research, we project its transformative impact on the future of cancer therapy. This exploration is aimed at paving the way towards an era of effectively managing this relentless disease, positioning EMT at the forefront of innovative cancer research strategies.

description: The theory of the orbital Hall effect (OHE), a transverse flow of orbital angular momentum in response to an electric field, has concentrated overwhelmingly on intrinsic mechanisms. Here, using a quantum kinetic formulation, we determine the full OHE in the presence of short-range disorder using 2D massive Dirac fermions as a prototype. We find that, in doped systems, extrinsic effects associated with the Fermi surface (skew scattering and side jump) provide $\approx 95\%$ of the OHE. This suggests that, at experimentally relevant transport densities, the OHE is primarily extrinsic.

Selection of representative stations by means of a cluster analysis for the BAMAR region in the PIDCAP period
Creators: name: Oesterle, H.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2002

description: A cluster analysis procedure is presented that allows to select stations that are typical for different meteorological conditions. The estimations of mean daily minimum and maximum air temperatures, and also mean daily precipitation were used as parameters of the classification procedure. The means are calculated using verified synoptic data which are collected in the course of interval from August to October 1995 at 950 synoptic sites allocated on the Baltex Model Area (BAMAR) region. As a result 83 representative stations are selected, and used for validation of the LM-model at PIK.

description: A flow-through experiment was conducted to study the effects of a simulated algal sedimentation (8.0 g C m-2) and the amphipod Monoporeia affinis (5000 ind. m-2) using well-oxidised sediment from the Gulf of Bothnia. Pore water nutrient profiles, nutrient fluxes, sediment denitrification and O2 consumption as well as NH4+ excretion of M. affinis were followed for 7 days. After the algal enrichment, the NO3- concentration fell to near zero in the pore water and a decrease in the denitrification rate was observed. This occurred since the concentration of NO3- in the flow-through water was low and coupled nitrification-denitrification formed the main denitrification pathway. The share of denitrification compared to other loss processes of N from the sediment reduced from 37% in the control cores to 0.7% in the algae treated cores. The efflux of NH4+ from the sediment formed 99% of the total loss of N in the algae treated cores. A massive efflux of NH4+ and PO43- was observed after the algal enrichment. The amphipods did not increase denitrification.

description: Aggravating the intensity and frequency of hazardous events and causing more threats to human lives, climate change has become a foremost environmental issue. With the emphasis of IPCC on the scientific understanding of vulnerability to climate change, the measurement of vulnerability is important not only to knowing to what extent an area is vulnerable to climate change, but also to the government of policy formulation in order to mitigate the extent of vulnerability. Till date, different methods have been developed using both econometric and index based approaches to measure vulnerability to climate change. This paper summarizes different approaches to measure vulnerability to climate change and the data related issues of these methods. The paper also presents the nexus between different methods and their applicability based on the available socioeconomic environment and the type of data concerned. The discussion on the use of different available methods by the later researchers in the succeeding section further enlarges the scope of use of these methods. Finally, we wind up the paper with some possible suggestions on the methods used to assess vulnerability to climate change for the later scholars.
The persistence of spatial patterns of beaching of current-driven pollution in a changing wind climate: a case study for the Gulf of Finland

description: We analyse long-term properties of current-driven transport of various items and substances to the nearshore from the vicinity of a fairway in the Gulf of Finland under the changing wind climate. The transport is replicated using semi-Lagrangian trajectories of parcels located at the sea surface. The trajectories are reconstructed with the TRACMASS model from surface velocity fields simulated by the Rossby Centre Ocean model for 1965–2004. The proportion of hits to the southern and northern nearshore varies in single years, but their long-term chances for being hit are equal. The number of hits to single nearshore sections greatly varies along the shore and in different years. The 5-year average spatial pattern of hits is highly persistent both qualitatively and quantitatively. Although the patterns of surface currents may have reacted to changes in the wind climate, the frequency and spatial patterns of beaching of current-driven pollution have remained unchanged over almost half century.

description: The observation of neutrinoless double-beta ($0νββ$) decay would offer proof of lepton number violation, demonstrating that neutrinos are Majorana particles, while also helping us understand why there is more matter than antimatter in the Universe. If the decay is driven by the exchange of the three known light neutrinos, a discovery would, in addition, link the observed decay rate to the neutrino mass scale through a theoretical quantity known as the nuclear matrix element (NME). Accurate values of the NMEs for all nuclei considered for use in $0νββ$ experiments are therefore crucial for designing and interpreting those experiments. Here, we report the first comprehensive ab initio uncertainty quantification of the $0νββ$-decay NME, in the key nucleus $^{76}$Ge. Our method employs nuclear strong and weak interactions derived within chiral effective field theory and recently developed many-body emulators. Our result, with a conservative treatment of uncertainty, is an NME of $2.60^{+1.28}_{-1.36}$, which, together with the best-existing half-life sensitivity and phase-space factor, sets an upper limit for effective neutrino mass of $187^{+205}_{-62}$ meV. The result is important for designing next-generation germanium detectors aiming to cover the entire inverted hierarchy region of neutrino masses.

description: The effect of boreal forest on the Earth's energy budget was estimated in field conditions in Hyytiälä, southern Finland. The indirect aerosol effect due to new particle formation, the effect of forest carbon sequestration and the effect of forestation- or deforestation-related albedo change were investigated. The young, fast-growing boreal forest was estimated to be a relatively significant carbon sink and an important aerosol source, and thus the effect on the Earth's energy budget was seen to be negative. The estimated values (reported as annually averaged energy budget perturbations per square meter of forest) were –36 W m–2 due to the carbon sink, +10 W m–2 due to the albedo effect and between –5 and –14 W m–2 due to the aerosol effect. However, the values are uncertain.

description: We analyzed the variability in diurnal xylem diameter in Scots pine (Pinus sylvestris) by comparing daily maximum, minimum and average diameters and daily amplitudes of variation with environmental variables related to transpiration and water uptake from the soil. The measurements were carried out during six summers, 1999–2004 at SMEAR II station in Hyytiälä, southern Finland. We found that the daily maximum, minimum and average diameters and amplitudes were closest related to daily average water vapor deficits (VPD) and soil water contents in A-horizon ([theta]A). However, the highest degree of determination was only 37%. That was found for daily minimum diameter by VPD. The degree of determination and correlation could be improved by making up variables that took into account the variation in factors related to transpiration and soil water availability. In that case the highest correlation (negative correlation) and coefficient of determination was found for daily minimum diameter by VPD scaled with [theta]A so that VPD was enhanced when soil water content was low (VPD* = VPD*([theta]Amin/[theta]A)). This could explain 50% of the variation in daily minimum diameters. The results emphasize the importance of both inflow- and outflow-related factors in explaining the water tension and water status of tree stems.

description: Building on scientific debates on the function of ethnically segregated urban neighbourhoods, this thesis spotlights newcomers’ arrival processes. Using the traditional arrival neighbourhood Dortmund-Nordstadt as an example, it analyses the everyday practices of newcomers and established migrants in accessing and sharing arrival-specific resources as well as the spaces in which encounters and resource exchanges take place. The thesis, which is based on three sub-studies, shows that certain arrival infrastructures and brokering practices located in arrival neighbourhoods can play a key role in facilitating newcomers’ access to resources. Alongside the many formal (municipal and civil society) advisory and support institutions, this study revealed that access to resources is often gained through social connections established in non-formal semi-public spaces, such as cafés, shops and service facilities or places of worship. Established migrants in these semi-public spaces often act as arrival brokers, significantly contributing to a newcomer’s arrival process. These findings demonstrate that traditional arrival neighbourhoods offer a variety of resource access opportunities for newcomers. These result from the existence of a vast range of knowledge and experience shared by a very diverse local population, as well as from a wide range of arrival-related infrastructures which, beyond their primary functions, offer opportunities for exchange and access to social networks. By highlighting the relevance of non-formal infrastructures and brokering practices at the local level, this thesis contributes to a better understanding of the role of place for migrant arrival.

We use quantum field theory at tree level to obtain the one-particle-emission amplitudes. We analyze and compare the energy spectrum and total energy released, which are calculated from these amplitudes, for particles with varying initial positions and for particles originating from infinity with varying kinetic energy. We also compare the results with those due to a falling charged "string" extended in the radial direction.

Distribution.
This species in known from Lesser Sunda islands, Java and Sulawesi islands, Indonesia.
Remarks.
Slightly variable smaller barriers. Some specimens of G. concreta had two and some three barriers between the lower palatal and columellar one. Interpalatal plica can be well developed or weaker.
We observed no differences between the type specimens of G. concreta and H. fruhstorferi. Van Benthem Jutting (1949 a) compared the newly described G. concreta with H. fruhstorferi but her decision was based on variable characters such as the level of detachment of the last whorl, broadness of the last whorl (which is, by us, not observed as different between the types) and level of keel development (namely slightly weaker in G. concreta, but this difference is very slight). We treat all these differences as intraspecific variability.

description: Globally, national regulatory authorities are both responsible and accountable for health and environmental decisions related to diverse products and risk decision contexts. These authorities provided regulatory oversight and expedited market authorizations of vaccines and other therapeutic products during the COVID-19 pandemic. Regulatory decisions regarding such products and situations depend upon well-established risk assessment and management steps. The underlying processes supporting such decisions were outlined in frameworks describing the complex interactions between factors including risk assessment and management steps as well as principles which help guide risk decision-making. In 2022, experts in risk science proposed a set of 10 guiding principles, further examining the intersection and utility of these principles using 10 diverse risk contexts, and inviting a broader discourse on the application of these principles in risk decision-making. To add to this information, Canadian regulatory practitioners responsible for evaluating health and environmental risks and establishing policies convened at a Health Canada workshop on Principles for Risk Decision-Making. This review reports the results derived from this interactive engagement and provides a first pragmatic analysis of the relevance, importance, and feasibility of such principles for health and environmental risk decision-making within the Canadian regulatory context.

description: We introduce the notion of refined unramified cohomology of algebraic schemes and prove comparison theorems that identify some of these groups with cycle groups. This generalizes to cycles of arbitrary codimension previous results of Bloch–Ogus, Colliot-Thélène–Voisin, Kahn, Voisin, and Ma. We combine our approach with the Bloch–Kato conjecture, proven by Voevodsky, to show that on a smooth complex projective variety, any homologically trivial torsion cycle with trivial Abel–Jacobi invariant has coniveau 1. This establishes a torsion version of a conjecture of Jannsen originally formulated ⊗Q. We further show that the group of homologically trivial torsion cycles modulo algebraic equivalence has a finite filtration (by coniveau) such that the graded quotients are determined by higher Abel–Jacobi invariants that we construct. This may be seen as a variant for torsion cycles modulo algebraic equivalence of a conjecture of Green. We also prove ℓ-adic analogues of these results over any field k which contains all ℓ-power roots of unity.
Meromixis as a part of lake evolution; observations and a revised classification of true meromictic lakes in Finland
Creators: name: Hakala, A.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2004

description: Based on Finnish lakes, meromixis is viewed from a paleolimnological perspective as a part of lake evolution. The study concludes that theoretical search of meromictic lakes is almost impossible, due to inconsistent and insufficient basic data and the complexity of meromixis as a phenomenon. An estimation of possible Finnish meromictic lakes turned out to be a few dozen. Meromictic lakes are more numerous than formerly expected, but still rare. Based on the present estimation, only one lake in 800 is truly meromictic. Their most probable geographical location, besides the coastal lakes, are the Salpausselkä end-moraine zone and the areas between the Salpausselkä zone, Ostrobothnia, the Kainuu Region, and the eastern border of Finland. Terminology concerning holomixis/meromixis is presently confusing and this study favors a strict use of the term meromictic and grouping complete and incomplete holomictic lakes as one group and true meromictic as another. The revised classification recognizes meromixis that has resulted from (1) flow/precipitation of saline water over freshwater or freshwater over saline water, (2) superficial diffuse nutrient load and/or turbidity currents from the catchment, (3) subsurface inflow of groundwater, (4) inadequate mixing due to the lake morphology and surrounding topography.

description: The article is focused on optical properties of nanostructures containing spherical gold nanoparticles of various radii. We explore correlation between the particle radius and the choice of permittivity model applied to describe optical absorption spectra of gold granules. The experiments show splitting of the absorption band of granular gold films to form a second absorption peak. The first peak is associated with the phenomenon of plasmon resonance, while the second one reflects quantum hybridization of energy levels in gold. Quantum effects are shown to prevail over size effects at a granule diameter of about 5-6 nm. The Mie theory gives a rigorous solution for the scattered electromagnetic field on a sphere taking into account optical properties of the latter, however, it does not specify the criteria for selecting a model to calculate dielectric permittivity. Both calculations and experiments confirm the limiting diameter of gold nanoparticles where the Hampe-Shklyarevsky model is applied. Meanwhile, this model is still unable to predict the splitting of the plasma absorption band. The data presented in the article can be used for a predetermined local field enhancement in composite media consisting of a biolayer and metal nanoparticles. The conducted research provides a deeper understanding of the influence of a terahertz high-intensity electromagnetic field localized in the space on quantum dots.

description: Generating bitmap graphics from text has gained considerable attention, yet for scientific figures, vector graphics are often preferred. Given that vector graphics are typically encoded using low-level graphics primitives, generating them directly is difficult. To address this, we propose the use of TikZ, a well-known abstract graphics language that can be compiled to vector graphics, as an intermediate representation of scientific figures. TikZ offers human-oriented, high-level commands, thereby facilitating conditional language modeling with any large language model. To this end, we introduce DaTikZ, the first large-scale TikZ dataset consisting of 120k TikZ drawings aligned with captions. We fine-tune LLaMA on DaTikZ, as well as our new model CLiMA, which augments LLaMA with multimodal CLIP embeddings. In both human and automatic evaluation, CLiMA and LLaMA outperform commercial GPT-4 and Claude 2 in terms of similarity to human-created figures, with CLiMA additionally improving text-image alignment. Our detailed analysis shows that all models generalize well and are not susceptible to memorization. GPT-4 and Claude 2, however, tend to generate more simplistic figures compared to both humans and our models. We make our framework, AutomaTikZ, along with model weights and datasets, publicly available.

description: It is very important to detect changes in forest productivity due to the global change on a large scale. In this work, the evolution of the vegetation in the Komi Republic (northwestern Russia) from 1982 to 2001 was analyzed using NOAA AVHRR PAL time series. A statistically significant correlation (adjusted r2 = 0.44–0.59) between Normalized Difference Vegetation Index (NDVI) data and tree ring width (261 living trees) was identified for the territory of the Komi Republic. The increased site productivity reflected an increase of integrated NDVI values from June to August. This allows NDVI to be used as a proxy for estimation of forest growth trends for the recent decades. A positive and significant trend in NDVI data was identified from 1982 to 2001, coinciding with an increase in site productivity in the study area. The decrease in precipitations coincided with an increase in site productivity (highest r2 was 0.71). The increase in productivity reflected in NDVI data is maximal on the sites with increased temperature and decreased precipitations. In the Komi Republic the distribution of the trends in NDVI data changes on the south-west to north-east gradient. NDVI data could be used to increase spatial resolution of tree ring width series. Taking into account the relatively small role of human activity in the Komi Republic compared with Europe, the site productivity during recent decades also increased in relatively untouched forests.

description: The aim of this study was to determine how accumulation of organic matter on the forest floor (logging residue piles) is reflected in the soil solution concentrations of dissolved organic C and N and other nutrients. The data were collected from a logging residue experiment 7 years after a clear-cut harvest of a Norway spruce stand growing on sandy soil. The solution retained in the soil matrix was extracted from soil samples by the centrifugation method. The study site was located in Paltamo, Finland. The logging residue levels were: (1) 40 kg m–2, (2) 10 kg m–2, and (3) 0 kg m–2 of fresh spruce branches. The DOC and DON concentrations were higher in the organic layer in the centrifuged soil solution due to organic matter accumulation on the forest floor as compared to the treatment where no accumulation had occurred, and these higher levels were persisting still seven years after the logging residues had been piled on the site. The NO3-N and NH4-N concentrations were generally very low. It was possible to accurately estimate the anion deficit based on the DOC concentration in the soil solution, and the increased concentration of DOC and organic anions strongly influenced the ionic balance of the centrifuged soil solution.

description: A range of observations points towards earlier onset of spring in northern high latitudes. However, despite the profound effects this may have on vegetation–atmosphere exchange of carbon (NEE), vegetation–atmosphere physical coupling, or the location of the tundra–taiga interface, the number of studies that investigate winter–spring transition fluxes in contrasting northern vegetation types is limited. Here, we examine spring ecosystem–atmosphere energy and carbon exchange in a Siberian pine forest and mire. Divergent surface albedo before and during snow-melt resulted in daytime net radiation (Rn) above the forest exceeding Rn above the mire by up to 10 MJ m–2. Until stomata could open, absorbed radiation by the green pine canopy caused substantial daytime sensible heat fluxes (H > 10MJ m–2). H above the mire was very low, even negative (< –2 MJ m–2), during that same period. Physiological activity in both ecosystems responded rapidly to warming temperatures and snow-melt, which is essential for survival in Siberia with its very short summers. On days with above-zero temperatures, before melt was complete, low rates of forest photosynthesis (1–2 umol m–2 s–1) were discernible. Forest and mire NEE became negative the same day, or shortly after, photosynthesis commenced. The mire lagged by about two weeks behind the forest and regained its full carbon uptake capacity at a slower rate. Our data provide empirical evidence for the importance the timing of spring and the relative proportion of forest vs. mire has for late winter/spring boundary-layer growth, and production and surface–atmosphere mixing of trace gases. Models that seek to investigate effects of increasingly earlier spring in high latitudes must correctly account for contrasting physical and biogeochemical ecosystem–atmosphere exchange in heterogeneous landscapes.

description: In this work, we delve into the realm of quantum chromodynamics (QCD) by calculating twist-4 chiral-even generalized parton distributions (GPDs), within the context of the light-front quark-diquark model (LFQDM), focusing specifically on the intriguing case of zero skewness. To shed light on the behavior of twist-4 chiral-even GPDs, we present comprehensive two-dimensional ($2$-D) and 3-dimensional ($3$-D) plots, mapping their dependence on the longitudinal momentum fraction ($x$) and the momentum transfer ($t$). Furthermore, our research looks into the profound connection between twist-4 chiral-even GPDs and other distribution functions (DFs), including parton distribution functions (PDFs), transverse momentum-dependent parton distributions (TMDs) and generalized transverse-momentum dependent parton distributions (GTMDs). Additionally, our investigation extends to the exploration of related higher twist form factors (FFs), which play a pivotal role in elucidating the internal structure of hadrons. To provide significant insights into the partons spatial distribution, we have also yielded impact parameter GPD plots.

description: We have investigated the pseudo-scalar meson structure in the form of transverse momentum-dependent parton distribution functions (TMDs) in the light-front based holographic model and quark model. Starting from leading order, we have calculated all the time-reversal even TMDs for pion and kaon up to twist-$4$ in these models. We have shown the 3-dimensional structure as well as the 2-dimensional structure of these particles along with their average quark transverse momenta. The parton distribution functions (PDFs) of pseudo-scalar mesons have been compared with the results of other models. The sum rules, TMD transverse dependence, inverse moments and Gaussian transverse dependence ratio in these models have also been studied. Further, the transverse quark densities have also been analyzed in the momentum space plane for these particles. The higher twist kaon properties in light-front dynamics have been predicted for the first time in this work.

description: Dry deposition of base cations, nitrate, as well as particulate ammonium, and sulphate in coniferous forests was measured using a surrogate surface in combination with net throughfall measurements at 11 sites in southern Sweden. The measurement technique involved monitoring gaseous pollutants with diffusive samplers and assuming common dry deposition rates on forest and the surrogate surface. The dry deposition of base cations was important as compared to the wet deposition at all coastal (windy) sites. Correlations of the internal fluxes of potassium and calcium were identified with regard to the deposition of reduced nitrogen compounds and sulphur dioxide respectively. In addition, the results outline the significance of dry deposition compared to wet deposition and trends relating to the net throughfall of nitrogen compounds. The net throughfall of nitrogen compounds was often negative, but approached the estimated dry deposition with increasing load.

description: On the basis of fifteen global model simulations of future climate, using the SRES emissions scenarios for greenhouse gases and aerosols, we have constructed national-scale seasonal and annual climate change scenarios for Finland during the 21st century. In approximate terms, the annual mean temperature is projected to rise by 1–3 °C and the annual mean precipitation by 0%–15% by the 2020s, relative to the baseline period 1961–1990. The corresponding increases by the 2050s are 2–5 °C (temperature) and 0%–30% (precipitation), while by the 2080s they are 2–7 °C and 5%–40%, respectively. The projected temperature trends are markedly stronger than that observed during the 20th century. The ranges in the climate change projections reflect the uncertainties arising from differences in model formulation and in emissions scenarios but are, to some extent, affected by the internal variability of climate as well. Seasonally, the projected precipitation changes and their statistical significance are largest in winter and smallest in summer. On the other hand, the projected rather small summertime warming is at least as statistically significant as the larger warming in the other seasons. Based on a literature review, it seems very likely that changes in mean climate are associated with changes in climate extremes as well.
Variability of pycnoclines in a three-layer, large estuary: the Gulf of Finland

description: Thirty-five surveys were conducted across the Gulf of Finland from 2006 to 2013 to study the characteristics and variability of the two pycnoclines in this stratified estuary. Easterly winds caused a shallower position of the upper pycnocline near the southern coast and the deeper pycnocline along the northern coast. Westerly winds had an opposite effect. Surfacing of the upper pycnocline (upwelling) was observed several times while the upper mixed layer was deeper than 40 m in the case of downwelling. The deeper pycnocline weakened and deepened significantly during the southwesterly wind bursts while it was observed at shallower depths than 50 m several times during the periods of easterly winds. The upper pycnocline was on average 3 m shallower near the southern coast while the deeper pycnocline was leveled. The inclination of the upper pycnocline corresponding to the average local wind forcing agrees well with the general cyclonic circulation of the upper layer in the Gulf of Finland and the water exchange estimates between the gulf and the Baltic Proper. An average seasonal inclination of the pycnoclines showed high inter-annual variability depending on the prevailing wind forcing. Easterly winds caused stronger vertical stratification and horizontal gradients across the gulf while in the case of westerly winds, horizontal and vertical gradients were weaker.
