description: Zusammenfassend kann gesagt werden, dass eine umfassende Untersuchung und Analyse eines Abwärtswandlers im Kontext eines Regelkreises wichtige Erkenntnisse über seine Leistungsfähigkeit, Stabilität und Zuverlässigkeit liefern kann. Die Auswahl der richtigen Komponenten wie Spulen, Kondensatoren und Widerstände sowie die optimale Einstellung der Regelparameter sind entscheidend, um die gewünschte Ausgangsspannung mit minimaler Welligkeit und hohem Wirkungsgrad zu erreichen.

Die Durchführung von AC-Analysen, insbesondere im Bode-Diagramm, ermöglicht eine genaue Abschätzung des Amplituden- und hasenverhaltens des Regelkreises. Dabei ist die Phasenreserve ein entscheidender Faktor für die Stabilität des Systems. Eine ausreichende Phasenreserve stellt sicher, dass der Regelkreis auf Änderungen reagieren kann, ohne in instabile Zustände zu geraten. Ein stabiler Regelkreis ist für eine zuverlässige Leistung und eine effektive Regelung unerlässlich. Insgesamt verdeutlicht die Analyse des Abwärtswandlers als Teil eines Regelkreises die komplexen Zusammenhänge zwischen den elektrischen Komponenten, den Regelparametern und der Systemstabilität. Durch eine sorgfältige Abstimmung und Optimierung dieser Parameter können robuste und zuverlässige Stromversorgungslösungen entwickelt werden, die den Anforderungen eines breiten Anwendungsspektrums gerecht werden.

Darüber hinaus bietet die stromgeführte Regelung im Vergleich zur spannungsgeführten Regelung mehrere Vorteile. Sie ermöglicht eine verbesserte Stabilität, eine bessere Dynamik und eine geringere Empfindlichkeit gegenüber Laständerungen. In einigen Anwendungen kann 
die stromgeführte Regelung auch einfacher zu implementieren sein.

description: After more than six years of build-up and basic research, the Baltic Sea Experiment (BALTEX) undergoes a transition into its second phase, where major attention is paid to provide a long-term data set, covering at least two complete seasonal cycles. This new phase called BRIDGE, is part of a world-wide effort to study energy and water cycles and also related fluxes of carbon and other constituents over continental-scale regions. Some of the major findings obtained during the first phase of BALTEX are summarized in this paper.
Wind wave breaking and aerodynamic roughness of the air-sea interface as seen from above and from below
Creators: name: Kitaigorodskii, S.A.
Publisher: name: Boreal Environment Research Publishing Board
Year: 1998

description: In this paper an attempt is made to explain some of the features of classical aerodynamic classification based on the effect of mobility of roughness elements (Kitaigorodskii 1968) for both sides of the air-sea interface by incorporating into such a classification the effect of breaking wind waves. Also the \fluctuating\ regime of the sea surface roughness discussed by Toba et al. (1991) is explained by taking into account the existence of the dissipation subrange (Kitaigorodskii 1983, 1986, 1992a, 1992b, 1997) and the inverse cascade of energy in the well developed wind wave field (Zaharoff and Zaslavskii 1982, and Kitaigorodskii 1983). In the last section of the paper a theory is proposed on how to incorporate the effect of wave breaking in the parametrization of the sea surface roughness as seen from below. It is shown that aerodynamically smooth conditions in the classical sense never exist below the sea surface, since effective turbulent viscosity due to shear free turbulence generated by wave breaking is much larger than molecular viscosity.

Publisher: name: Boreal Environment Research Publishing Board
Year: 2021

description: In this study, we apply an ice thermodynamic model to a shallow freshwater lagoon in the south-eastern part of the Baltic Sea — the Curonian Lagoon. The model results were compared with the measurement data from three near‑shore stations during the period of 2004–2017. The simulation data showed the model to be capable of replicating ice thickness dynamics rather well (mean R = 0.92, RMSE = 6 cm). Although the model overestimated the number of ice days (NID) on average by one month (ranging from 3 to 40 days), the overall pattern was very similar to observations (R = 0.95). We further assessed the ice thickness and NID projections in the near (2021–2040) and far (2081–2100) future under two climate change scenarios (RCP4.5 and RCP8.5). The results showed that the mean (max) ice thickness could decrease by 10–49% (6–34%) in the near and 41–75% (22–55%) in the far future under RCP4.5, and by 2–52% (2–30%) in the near and 75–88% (50–71%) in the far future under RCP8.5 compared to the baseline period of 1986–2005. The NID will shorten by 9–19% (9–22%) in the near and 15–36% (46–57%) in the far future under RCP4.5 (RCP8.5) scenarios, compared with the baseline period.

2D point vortex dynamics in bounded domains: global existence for almost every initial data
Creators: name: Donati, Martin
Publisher: name: arXiv

Subjects: subject: Analysis of PDEs (math.AP)

subject: FOS: Mathematics

description: In this paper, we prove that in bounded planar domains with $C^{2,α}$ boundary, for almost every initial condition in the sense of the Lebesgue measure, the point vortex system has a global solution, meaning that there is no collision between two point-vortices or with the boundary. This extends the work previously done in [13] for the unit disk. The proof requires the construction of a regularized dynamics that approximates the real dynamics and some strong inequalities for the Green's function of the domain. In this paper, we make extensive use of the estimates given in [7]. We establish our relevant inequalities first in simply connected domains using conformal maps, then in multiply connected domains.

title: The pricing of European non-performing real estate loan portfolios: evidence on stock market evaluation of complex asset sales
Creators: name: Manz, Florian
name: Müller, Birgit
name: Schiereck, Dirk
Publisher: name: Springer
Year: 2024

description: Recent empirical evidence raises doubt about the ability of financial market participants to generate information efficient valuations for capital market instruments whose cash flows are related to residual claims and dependent on real estate income. We contribute to this literature with the examination of value implications of non-performing loan (NPL) divestitures in the banking industry during the period 2012–2018. In a first step, we provide descriptive statistics of the European NPL market, which lacks transparency and publicly available basic information on portfolio size and components. We then analyze wealth effects of distressed loan sale announcements for a uniquely large transaction database with 317 NPL deals, which is largely driven by real estate collateral. Our results show positive stock market reactions for vendor banks following NPL divestitures that tend to be driven by real estate collateral and a size effect.
Monetary assessment of the impacts of forestry on water-based benefits in Finland
Creators: name: Matero, J.
name: Saastamoinen, O.
Publisher: name: Boreal Environment Research Publishing Board
Year: 1998

description: This paper identifies the major impacts of forestry on watercourses, introduces methods and calculation approaches for valuing these impacts in monetary terms and presents some preliminary estimates of the economic value (order of magnitude) of damages to different water-based values. Using a variety of calculation approaches, the range of aggregated damages was estimated to be 17–93 million FIM per year if even the more uncertain (guess-estimate type) figures of general recreation, biodiversity and crayfish fisheries were included. The main components in this estimate were the impacts on flood protection and water-based recreation. The range of aggregated damage estimates corresponds to 0.2–1.0% of the GDP of forestry in Finland in 1992. However, due to data and methodological problems in some specific impact estimations, and those related to individual valuation and summation procedure in general, even the total range remains tentative.

description: We analyzed size distributions measured continuously at a boreal forest measurement site at Hyytiälä, Finland between 1996 and 2003. From the eight-year data we identified days when new aerosol particle formation was taking place as well as days when no formation was detected, removing days with ambiguous status. The event days were then classified based on whether it was possible to determine formation and growth rates of new particles. These characteristics were then calculated. We found that new particle formation happens frequently in the boreal forest boundary layer, with at least 24% of days containing an event. Events are more probable during spring and autumn than during other times of the year. The average formation rate of particles larger than 3 nm was 0.8 cm–3 s–1, with enhanced rates during spring and autumn. The mean growth rate was 3.0 nm h–1, peaking in summer. The created event database is valuable for future studies of reasons leading to new particle formation in the atmosphere.

description: We show that there exists a natural analogue of the Yang-Mills equations using the Frölicher-Nijenhuis bracket between vector-valued differential forms. The gauge field is a rank-two tensor, and when one constrains it to be symmetric, then the system exhibits fractonic behaviours. In the linearised limit, the constrained equations of motion reduce to those of the covariant fracton model [Bertolini-Maggiore 2022].

Energy and water balance of the Baltic Sea derived from merchant ship observations
Creators: name: Lindau, R.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2002

description: Individual merchant ship observations from COADS (Comprehensive Ocean Atmosphere Data Set) were used to determine the energy and water budget of the Baltic Sea for the period 1980 to 1995. On a monthly time scale these ship reports provide reasonable estimates for the radiative and turbulent fluxes and the precipitation despite their concentration on narrow shipping routes, because of the large correlation lengths for monthly means. In order to take into account the effects of sea ice on evaporation and albedo, the ice-covered parts of the Baltic Sea are treated separately, where we applied a simple thermodynamic ice model using ice information from the GISST (Global sea Ice coverage and Sea Surface Temperature) data set. As the overall result we found a small surplus of rain compared to evaporation (5 mm per month) and a quasi-balanced energy budget (1 W m–2 energy loss of the sea surface).
Metals in sediments of inland waters of Latvia

Year: 2001

description: Multielement analysis (by means of instrumental neutron activation analysis — INAA) of sediments in streams and lakes in Latvia was conducted. Total element concentrations, their variability and their speciation forms in sediments (exchangeable, carbonate bound, iron-manganese oxide bound, organic matter bound and residual) were compared. Increased metal concentrations were found in the lower reaches of the largest rivers and locally around known industrial pollution sources. Metal concentrations in stations from different regions of Latvia were related to natural geochemical processes and contamination levels. Metal speciation analysis showed that the dominant metal species were residual metals and those bound to organic matter. Residual and carbonate-bound forms dominated only in rhitral regions of rivers. The concentrations of exchangeable metals increased below pollution sources. Metal concentrations were compared with their geochemical mean values.
Wet deposition efficiency of short-lived radon-222 progeny in central Finland

Publisher: name: Boreal Environment Research Publishing Board
Year: 1999

description: The washout efficiency of 214Pb, a short-lived daughter nuclide of 222Rn, was studied by measuring external gamma radiation at Tikkakoski, Central Finland, in 1995. A mean washout ratio (volume per volume) of 1.2 x 106 was obtained in this study. According to the results, rain removes airborne 214Pb more efficiently than snow, which is in agreement with earlier studies. Higher washout ratio values were encountered during afternoon hours than during early morning hours, a result which is associated with the better vertical mixing of the lower troposphere during afternoon hours. The observed inverse correlation between washout ratio and rain intensity supports the earlier results that below-cloud scavenging processes are less efficient removal mechanisms of airborne 214Pb compared to in-cloud processes. The highest washout ratios were measured during westerly winds, which are usually associated with cyclones travelling from the North Atlantic Ocean in an easterly direction. The results obtained in this study can also be applied to fallout estimates of wet-depositing chemical substances, e.g. airborne sulphate or heavy metals, for which equivalent remote-sensing methods, such as that involving gamma radiation in this case, may not be available.

description: We consider the effect of spin-orbit coupling on a two-dimensional Kondo Lattice model, in which conduction electrons are antiferromagnetically coupled to a Yao-Lee spin liquid. When a Rashba spin-orbit interaction and a nearest-neighbor Kondo interaction is introduced, the low-energy Majorana bands become gapped and develop Chern numbers, protecting unidirectionally propagating Majorana edge modes. Our model describes a chiral topological superconductor with fractionalized charge-$e$ order parameter and spontaneously broken time-reversal symmetry, which may be of interest for certain heavy fermion superconductors, such as UTe$_2$.

Resolving species-specific abundances of three cold-water dinoflagellates using a simple staining technique
Creators: name: Lipsewers, Tobias
Publisher: name: Boreal Environment Research Publishing Board
Year: 2023

description: The dinoflagellates Gymnodinium corollarium (Gc), Biecheleria baltica (Bb), and Apocalathium malmogiense (Am) are very difficult to separate using traditional light microscopy. Their dominance patterns may have ecosystem-wide consequences in terms of, e.g., the Baltic Sea carbon cycle. This study describes a protocol to separate them, determines their relative abundances, and suggests the adjustment of monitoring programs. A relatively simple staining technique was found to be suitable to identify Gc, Bb, and Am. Opposite trends were observed for Gc (increasing) and Bb (decreasing) along with the spring bloom, indicating different niches. Two clusters of sub-basins were identified: 1) almost absolute dominance of the usually grouped biomass by Gc; and 2) Bb also became dominant. Gc occasionally dominated even the overall microscopy-derived biomass, Bb clearly contributed, and Am contributed minor proportions. The proposed strategy can be implemented in monitoring protocols. This will facilitate the tracking of changes within Baltic Sea phytoplankton assemblages.

description: Decadal trends in regional climate are investigated for their possible influence on the shoreline changes at a number of Baltic Sea sites in Estonia. Between 1951 and 2020, the annual mean surface air temperature at coastal stations has increased by 2.2–2.6°C, with no clear trends detected in the number of storm days during 1966–2020. However, a period of increased storminess was observed in the 1980s and 1990s. Due to post-glacial land uplift, with geocentric values between 1.3–3.5 mm yr–1, the mean relative sea level has been nearly stable or slightly falling during the study period, while the annual maxima have increased everywhere along the Estonian coast. Changes in wind regime and sea ice climate have caused temporal variations in sea level and wave conditions and, ultimately, manifested themselves in shoreline trends. Along the depositional segments, a relatively low activity of shore processes with slow erosion of the seabed and limited progradation of the beaches occurred before the 1980s. Following a clear shift in climatic conditions since the end of the 1980s and diminishing ice cover conditions along the coast, frequent storms accompanied with high sea levels resulted in increased activity of shore processes and substantial changes in alongshore morphology and beach profiles, and following an intense storm Gudrun (2005), minor events have not had substantial impact on the shore processes, with majority of the beaches attaining a new equilibrium morphodynamic state.

Type locality.
“ Tam Sua Hill, Utong District, Supanburi Province, 14°34'27"N, 99°46'26"E, 80 meters elevation ”.
Differential diagnosis.
This species is similar to two Hypselostoma which share the completely (or almost completely) flat shell with strongly upturning last whorl (H. khaowongkot and H. tridentatum). From them, it most obviously differs by its hooked upper and lower palatal plicae which are blunt in the former.
Distribution.
This species is known from two provinces in Thailand, Supanburi (type locality) and Kanchanaburi (this study).
Remarks.
In some specimens, previous whorls are partly sunken into the last while in others completely.
2. Hypselostoma hungerfordianum group
Diagnosis. Hypselostoma hungerfordianum group is characterised by a peculiar shell surface sculpture, as if “ scaly, granulated ”. This surface sculpture is unique and we assume that all the species which share this trait are possibly more closely related.
Remarks. This group has representatives across Southeast Asia and includes 19 species. The distribution spans from Kayin State in Myanmar and eastwards to western Cambodia (Battambang Province). Southernmost localities are known in Peninsular Malaysia while northernmost come from Loei Province in Thailand.

The crop has comparative advantage as high yielding and fast-growing crop sand has frequently been used as crisis response crop following natural disasters in Africa. In the light of this, the paper reviewed the Sources of Information on Crop Production in Nigeria, Adoption of Sweetpotato Production and Processing Technologies in Nigerian and Constraints to Adoption of Sweetpotato Improved Technologies.

description: The study focused on 40 reaches of 29 short narrow shallow watercourses on Saaremaa Island. The floristic list covers 68 taxa of vascular plants, including 14 species of true or obligate water plants, 18 taxa of amphibious plants, and 36 taxa of terrestrial plants. The article presents differences in the frequency of vascular plants between the watercourses of Saaremaa and mainland Estonia. Three taxa of macroalgae were new to Estonia. Ranunculus aquatilis, Berula erecta, and Alisma plantago-aquatica preferred a higher content of nitrogen compounds. However, Lemna minor, Veronica anagallis-aquatica, and Agrostis stolonifera var. prorepens preferred a higher content of phosphorous compounds. Cladophora rivularis preferred both higher nitrogen and phosphorous compounds in water. Potamogeton natans and Equisetum fluviatile preferred softer sediments, and Ulothrix zonata preferred relatively low pH values.

description: We investigate generic inequalities of various contributions to the shear modulus $μ$ in ensembles of amorphous elastic bodies. We focus first on a simple elastic network model with connectivity matrices (CMs) which are either annealed or quenched, at or out of equilibrium. The stress-fluctuation formalism relation for $μ$ is rewritten as $μ= μ_1 + μ_a$ with $μ_1 \ge 0$ characterizing the variance of the quenched shear stresses and $μ_a$ being a simple average over all states and CMs. For equilibrium CM-distributions $μ_a$ becomes equivalent to the shear modulus of annealed systems, i.e. $μ_a \ge 0$, while more generally $μ_a$ may become strongly negative as shown by considering a temperature quench and a scalar active two-temperature model. Consistent relations are also found for glass-forming colloids where $μ-μ_1=μ_a=0$ for equilibrium ensembles, i.e. $μ$ is set by the quenched shear stresses, while $μ_a$ becomes again negative otherwise.

description: The expected Euler characteristic (EEC) curve of excursion sets of a Gaussian random field is used to approximate the distribution of its supremum for high thresholds. Viewed as a function of the excursion threshold, the EEC is expressed by the Gaussian kinematic formula (GKF) as a linear function of the Lipschitz-Killing curvatures (LKCs) of the field, which solely depend on the domain and covariance function of the field. So far its use for non-stationary Gaussian fields over non-trivial domains has been limited because in this case the LKCs are difficult to estimate. In this paper, consistent estimators of the LKCs are proposed as linear projections of "pinned" observed Euler characteristic curves and a linear parametric estimator of the EEC curve is obtained, which is more efficient than its nonparametric counterpart for repeated observations. A multiplier bootstrap modification reduces the variance of the estimator, and allows estimation of LKCs and EEC of the limiting field of non-Gaussian fields satisfying a functional CLT. The proposed methods are evaluated using simulations of 2D fields and illustrated in thresholding of 3D fMRI brain activation maps and cosmological simulations on the 2-sphere.
Rain observations with a vertically looking Micro Rain Radar (MRR)

description: Measurements of rain were obtained with a vertically pointing micro radar (MRR) with 1 min time resolution and 50(100) m height resolution at the German Baltic coast on the Zingst peninsula (54.43°N, 12.67°E). The comparison with a conventional rain gauge (30 min integration time) for a five months summer period show a correlation coefficient of [[rho][eta][omicron]] = 0.87 for the rainrate and agreement within 5% for the total rainfall integrated over the whole period. Single measurements with 30 min integration time showed deviations up to a factor of 2 between MRR and rain gauge. Classification of the measurements into rainrate intervals shows that rainrates around 0.2 mm h–1 provide the highest contribution per rainrate interval to the total rainfall. Typical distributions of number-concentration, liquid-water- concentration and rainrate versus drop size, retrieved with the MRR, are presented. Simultaneous estimates of rainrate and reflectivity factor with data of a C-band (frequency 6 GHz) weather radar suggest that the MRR may be used to support quantitative rainrate estimates with weather radars. The weather radar used for comparison is operated by the German Weather Service and is situated 51 km from the MRR.

description: In the boreal zone, surface waters mostly receive external organic matter (OM) from surrounding peatlands. The lake’s biological communities may respond to changes in OM inputs caused by anthropogenic activities in the catchment. Testate amoebae (TA) possess an outer shell that preserves well in lake sediments and are commonly used in paleo-environmental studies. Additionally, they fall into the size range of particles transported from peatlands to lakes, making them potential particle tracers. Here, we compared TA communities of current and pre-peat extraction sediments from lakes receiving OM only from peat extraction areas (impact lakes) with lakes receiving OM from peatlands under other uses (control lakes). We found no differences between control and impact lakes, neither between current and pre-peat extraction. In conclusion, there is either no significant increase in the amount of organic matter discharge from peatland areas, or dislodged testate amoeba are retained in areas upstream of the lakes.
Evaluation of different harvest strategies for a vendace population with highly variable recruitment: a simulation approach
Creators: name: Marjomäki, T. J.
Publisher: name: Boreal Environment Research Publishing Board
Year: 2005

description: In the auto-regulative commercial vendace fishery, the fishing effort is increased if stock decreases in order to reduce interannual variation in supply and revenue. When the revenue per unit effort reaches a profitability threshold, fishing ceases. The performance of this strategy was compared with constant effort and constant revenue strategies combined with different threshold levels of fishing shut-down. A simulation model of an age-structured vendace population was applied. Qualitatively the results were very similar for the Ricker and Cushing stock-recruitment curves with or without negative dependence between consecutive recruitments. The interannual variability of revenue increased with an increase in mean revenue when approaching maximum mean annual revenue. Given a low threshold, the constant effort strategy performed best and constant yield worst with respect to the objectives of maximum mean revenue, low mean effort, and low risk for spawning biomass. For the constant effort strategy, the revenue variation was already high at low revenue levels. For the strategy aiming at constant revenue, the variation was low at a low revenue level but increased rapidly with increasing revenue. At a moderate revenue level, the intermediate strategy produced good trade-offs of rather high mean revenue with reasonable variation and risk to reproduction. A tendency for two-year-cyclicity appeared at a low mean spawning stock level. When the threshold of fishery shut-down was increased, the variability in revenue increased for every strategy and differences in their performance decreased. Simultaneously, the risk of low spawning stock decreased. The threshold regulation increased the instability of stock in cases of high fishing effort. Means for regulating the access to fishing should be established in order to ensure the possibility of flexibility of fishing effort and tolerable revenue variation. Some threshold regulation to protect the spawning stock is also necessary.

description: Background In response to the healthcare needs of patients experiencing homelessness, there has been a growing interest in street medicine to provide healthcare services to this vulnerable population. However, formal education on high-quality healthcare for unhoused individuals remains limited in medical education. Actions, Methods, or Interventions A student-initiated street medicine organization developed and implemented a curriculum to leverages a combination of self-directed online learning and street-based education. Clinical students in their third and fourth years of medical school participated in this program, which encompassed self-paced online didactics, personal reflection exercises, clinical street experiences, and curriculum-based near-peer “car talks” (Table 1). The didactic elements of the curriculum are designed to benefit all learners (Table 2), and the clinical and precepting components complement the online experiences. Results Over a 24-month period, 12 students completed a 4-week elective. Among the 10 students who completed both pre- and post-course Health Professional’s Attitudes Toward the Homeless Inventory (HPATHI) surveys (Table 3), statistical analysis revealed significant improvements in personal advocacy (F=7.57, P<0.05), social advocacy (F=6.49, P<0.05), cynicism (F=6.23, P<0.05), and the total HPATHI score (F=11.79, P<0.01) (Table 4; Figure 1). Lessons Learned The combination of online modules and service-learning activities in the elective improved students' attitudes toward individuals experiencing homelessness. The success of this program demonstrates the potential for positive change in the perceptions and advocacy of future healthcare professionals. This approach also highlights the importance of addressing disparities in medicine and fostering empathy among medical students. Future Application and Next Steps The model developed in this study offers a promising framework for other medical schools seeking to establish their own street medicine electives in collaboration with their own community partners. By adapting and implementing similar programs, medical schools can contribute to changing the narrative around homelessness and promoting compassionate healthcare practices. Next steps involve refining and expanding this curriculum and evaluating its impact on a larger scale. This approach has the potential to help produce a generation of healthcare professionals with improved attitudes and advocacy for those experiencing homelessness.

description: We study the distribution of extensions of a number field $k$ with fixed abelian Galois group $G$, from which a given finite set of elements of $k$ are norms. In particular, we show the existence of such extensions. Along the way, we show that the Hasse norm principle holds for $100\%$ of $G$-extensions of $k$, when ordered by conductor. The appendix contains an alternative purely geometric proof of our existence result.
