Published: April 2024

AbstractCloud storage adoption has increased over the years given the high demand for fast processing, low access latency, and ever-increasing amount of data being generated by, e.g., Internet of Things applications. In order to meet the users’ demands and provide a cost-effective solution, cloud service providers offer tiered storage; however, keeping the data in one tier is not cost-effective. In this respect, cloud storage tier optimization involves aligning data storage needs with the most suitable and cost-effective storage tier, thus reducing costs while ensuring data availability and meeting performance requirements. Ideally, this process considers the trade-off between performance and cost, as different storage tiers offer different levels of performance and durability. It also encompasses data lifecycle management, where data is automatically moved between tiers based on access patterns, which in turn impacts the storage cost. In this respect, this article explores two novel classification approaches, rule-based and game theory-based, to optimize cloud storage cost by reassigning data between different storage tiers. Four distinct storage tiers are considered: premium, hot, cold, and archive. The viability and potential of the proposed approaches are demonstrated by comparing cost savings and analyzing the computational cost using both fully-synthetic and semi-synthetic datasets with static and dynamic access patterns. The results indicate that the proposed approaches have the potential to significantly reduce cloud storage cost, while being computationally feasible for practical applications. Both approaches are lightweight and industry- and platform-independent.

Published: April 2024

AbstractSatellite-based precipitation estimates and global reanalysis products bear the promise of supporting the development of accurate and timely climate information for end users in sub-Sharan Africa. The accuracy of these global models, however, may be reduced in data-scarce regions and should be carefully evaluated. This study evaluates the performance of ERA5 reanalysis data and CHIRPS precipitation data against ground-based measurements from 167 rain gauges in Ethiopia, a region with complex topography and diverse climates. Focusing over a 38-year period (1981–2018), our study utilizes a point-to-pixel analysis to compare daily, monthly, seasonal, and annual precipitation data, conducting an evaluation based on continuous and categorical metrics. Our findings indicate that over Ethiopia CHIRPS generally outperforms ERA5, particularly in high-altitude areas, demonstrating a better capability in detecting high-intensity rainfall events. Both datasets, however, exhibit lower performance in Ethiopia's lowland regions, possibly the influence of sparse rain gauge networks informing gridded datasets. Notably, both CHIRPS and ERA5 were found to underestimate rainfall variability, with CHIRPS displaying a slight advantage in representing the erratic nature of Ethiopian rainfall. The study’s results highlight considerable performance differences between CHIRPS and ERA5 across varying Ethiopian landscapes and climatic conditions. CHIRPS’ effectiveness in high-altitude regions, especially for daily rainfall estimation, emphasizes its suitability in similar geographic contexts. Conversely, the lesser performance of ERA5 in these areas suggests a need for refined calibration and validation processes, particularly for complex terrains. These insights are essential for the application of satellite-based and reanalysis of rainfall data in meteorological, agricultural, and hydrological contexts, particularly in topographically and climatically diverse regions.
Predictors for long-term relapse of orthodontic treatment in patients with cleft lip and palate. A clinical follow-up study
Authors: Achterrath Sarah , Graf Isabelle , Guevara Romeo , Braumann Bert , Kruse Teresa 
Published: April 2024

Abstract
Objectives
To identify predictors for long-term relapse of orthodontic therapy in patients with cleft lip and palate (CLP).

Materials and methods
Patients with uni- and bilateral non-syndromal CLP were followed up at least two years after completion of their orthodontic therapy. Plaster casts of the start of treatment (T1), after completion of treatment (T2), and at follow-up (T3) were measured using the modified Huddart Bodenham Index. Characteristics of multidisciplinary therapy were taken from the patient files. Potentially influencing factors of relapse were investigated using logistic regression analyses and Spearman correlations.

Results
In total 58.07% of the included 31 patients showed a stable treatment outcome at follow-up after an average of 6.9 years. Even if relapse occurred, 61.54% of these patients still showed improvement regarding their occlusion compared to baseline. Predictors for the occurrence of relapse were the severity of dysgnathia at baseline (p = 0.039) and the extent of therapeutic change (p = 0.041). The extent of therapeutic change was additionally a predictor for the extent of post-therapeutic relapse (ρ = 0.425; p = 0.019).

Conclusions
Patients with CLP benefit from their orthodontic therapy in the long term despite an increased tendency to relapse.

Clinical relevance
Results of this long-term study could be used to adapt the treatment concept for patients with CLP and reinforce the significance of a patient-centered orthodontic treatment concept for affected patients.
Paleolimnological evidence for primary producer change linked to hydrologic connectivity and human impacts in Lake Carlton, Florida, USA
Authors: Clift Troy L. , Waters Matthew N. 
Published: April 2024

AbstractHypereutrophic conditions in lake ecosystems are generally associated with nutrient inputs from surrounding terrestrial landscapes. However, some systems can receive primary nutrient inputs through hydrologic connections such as rivers or canals. Lake Carlton, Florida, USA is a small, shallow, polymictic lake that ends a hydrologically connected string of lacustrine systems with hypereutrophic lakes Beauclair and Apopka. Lake Beauclair and Lake Apopka were connected hydrologically when a system of canals was constructed beginning in 1893 CE. These lakes have maintained hypereutrophic conditions despite extensive management to reduce nutrient inputs. Here, we collected a sediment core from Lake Carlton to accomplish two primary research objectives: 1) reconstruct the nutrient input for Lake Carlton throughout the last ~ 150 years to conduct source assessment, and 2) link primary producer changes with management actions between lakes Apopka, Beauclair, and Carlton. Paleolimnological tools were applied to a 165-cm sediment core and analyzed for bulk density, organic matter content, nutrients (C, N, P), photosynthetic pigments, and total microcystins. Sediments were dated using 210Pb and results indicate that the core represents over 150 years of sediment accumulation. Sedimentary nutrient concentrations show that the primary driver of nutrient inputs resulted from canal construction, beginning in 1893 CE, which corresponded to increased nutrient deposition. Photosynthetic pigment data indicate dramatic increases in most primary producer groups coinciding with the hydrologic modification. However, around ~ 1970 CE, primary producer communities shifted from diatom dominance to cyanobacterial dominance, which appeared to be linked to internal nutrient dynamics and competition among phytoplankters within the lake ecosystem. Cyanotoxin production records show a significant lag between cyanobacterial dominance and peak cyanotoxin production with toxins increasing in the last 30 years. These data demonstrate that local nutrient inputs do not govern all phytoplankton dynamics in shallow lake systems but must be interpreted considering hydrologic alterations and management practices.

Abstract
Purpose
To evaluate the efficacy and safety of oral ibrexafungerp (HS-10366) versus placebo in Chinese patients with vulvovaginal candidiasis (VVC).

Methods
A double-blind, placebo-controlled, randomized, multicenter phase III study was conducted in symptomatic VVC patients. Patients received (2:1) twice-daily oral ibrexafungerp 300 mg or matching placebo for 1 day. The primary endpoint was clinical cure (vulvovaginal signs and symptoms [VSS] score = 0) at test-of-cure (TOC) on day 11 ± 3. The secondary endpoints included mycological eradication, overall response, and clinical improvement (VSS score ≤ 1) at TOC, and vulvovaginal symptom resolution at follow-up on day 25 ± 4.

Results
In total, 360 patients were included in the modified intention-to-treat set (defined as positive Candida cultured and receiving at least one study drug; 239 for ibrexafungerp, 121 for placebo). Compared with placebo, patients receiving ibrexafungerp had a significantly higher proportion of clinical cure (51.0% vs. 25.6%), mycological eradication (55.6% vs. 18.2%), overall response (33.9%, vs. 8.3%) at TOC and complete symptom resolution (74.5% vs. 39.7%, all P < 0.001) at follow-up. Subgroup analysis of clinical cure indicated that patients with C. albicans could benefit from ibrexafungerp over placebo. A similar benefit trend was also observed in those with non-albicans Candida by post-hoc analysis. Further analyses revealed similar efficacy of ibrexafungerp between patients with fluconazole non-susceptible C. albicans and fluconazole susceptible C. albicans regarding clinical cure and mycological eradication. Ibrexafungerp was generally well tolerated. Adverse events were primarily gastrointestinal and were mainly mild in severity.

Conclusions
As a first-in-class antifungal agent, ibrexafungerp demonstrated promising efficacy and favorable safety for VVC treatment in Chinese patients.

Nutrition Evaluation and Counseling for Potential Living Kidney Donors: An Opportunity for Lifelong Change
Authors: Friedman Golnaz Ghomeshi , Perez Richard , Chen Ling-Xin 
Published: April 2024

Abstract
Purpose of Review
In this review, we discuss the importance of nutrition evaluation and counseling for living kidney donor candidates (LKDCs) and the roles of the dietitian and transplant physician.

Recent Findings
In the past decades, living kidney donors are becoming older and have higher rates of obesity and glucose intolerance. Like all adult populations, living kidney donors are at risk for developing diabetes, obesity, hypertension, and kidney disease post-donation, and risks may rise as these chronic diseases rise in the general population. Further, implications may be more serious for individuals living with one kidney. However, involvement of the dietitian in the evaluation of LKDCs may vary across transplant centers. Current US policies do not absolutely require a Registered (Transplant) Dietitian to be involved in the care of LKDCs during the various phases of donation.

Summary
Dietitians should be involved in the evaluation of all LKDCs. Individualized lifestyle-focused, sustainable nutrition counseling should be provided to all LKDCs. Transplant clinicians should engage in nutrition counseling of LKDCs as this can increase the impact of the intervention. Nutrition evaluation and counseling can lead to life-long change for the LKDC.
Urban water bodies mitigate heat waves, the case of the Chinese city Kunming

Published: April 2024

AbstractWith the continuous deepening of global warming and urbanization processes, the frequency and intensity of extreme weather events are increasing. Additionally, the increase in energy usage exacerbates climate change. The water cold island (WCI) effect of urban water bodies plays a vital role in mitigating urban heatwaves. This paper focuses on the main urban area of Kunming as the research area. Using the lansat8-OLI image data as the data source, surface radiant temperature is inversely derived through atmospheric correction, resulting in a temperature grading map. Based on the high-resolution imagery from Google Earth, 16 water bodies in Kunming were visually interpreted. By establishing buffer zones and extracting landscape indices, methods were used to quantitatively analyze the average internal temperature of the water bodies, water cold island intensity (WCI), and the maximum cooling distance (LMAX) of the water bodies. The results show that: (1) The overall pattern of the Cool Island in the main urban area of Kunming City shows a trend of being weak inside and strong outside. (2) Riparian green space area is a key factor influencing the average temperature of water bodies, and it is significantly nonlinearly correlated with the average temperature of water bodies. (3) Multiple factors influence WCI. It is significantly positively correlated with the area of water bodies and the dispersion of green spaces, indicating that riparian green spaces promote the cooling of water bodies.

Abstract
To overcome Yb lasing, a kilowatt-level 1535 nm fiber laser is utilized to in-band pump an Er:Yb co-doped fiber (EYDF) amplifier. The output power of a 301 W narrow-linewidth EYDF amplifier operating at 1585 nm, with 3 dB bandwidth of 150 pm and

${M}^2$

< 1.4, is experimentally demonstrated. To the best of our knowledge, it is the highest output power achieved in L-band narrow-linewidth fiber amplifiers with good beam quality. Theoretically, a new ion transition behavior among energy levels for in-band pumping EYDF is uncovered, and a spatial-mode-resolved nonlinearity-assisted theoretical model is developed to understand its internal dynamics. Numerical simulations reveal that the reduction in slope efficiency is significantly related to excited-state absorption (ESA). ESA has a nonlinear hindering effect on power scaling. It can drastically lower the pump absorption and slope efficiency with increasing pump power for in-band pumped EYDF amplifiers. Meanwhile, optimized approaches are proposed to improve its power to the kilowatt level via in-band pumping.

Published: April 2024

AbstractThe norms of labor law that regulate the relevant relationship between the employee and the employer are constantly evolving under the influence of various factors, including society and the State. Labor law trends have become especially prominent over the past several years, particularly during the COVID-19 pandemic. Lockdown restrictions have dealt a serious blow to the labor field and have required urgent action from both companies and governments. In view of this, a number of relevant subtopics have been formed in labor relations, the study of which is of interest to the entire scientific community. The purpose of the research paper is to study the main trends that have emerged in modern labor law and their impact on the formation of the labor legislation system in Ukraine and the European Union (EU) from a comparative perspective. The article analyzes the main directions that the authors have identified as especially relevant in the development of labor relations and the legal regulation of such issues. Considering that some trends have arisen spontaneously under the influence of the COVID-19 pandemic, and many States were not ready for them, we have analyzed how the legislator settled such issues. The laws of Ukraine, the EU, and individual EU member States are examined here in a comparative perspective to draw upon and understand a complete picture of the modern development of labor relations in Europe and to identify the most beneficial approaches to regulating topical issues of labor law. The information obtained as a result of the study can be used to improve Ukraine's national legislation, bring it in line with European standards, further study the issue of the modern development of labor relations, and teach and develop methodological support for educational disciplines related to labor law and social security law.
The Late Miocene Talpidae (Eulipotyphla, Mammalia) from the Pannonian Region, Slovakia
Authors: Cailleux Florentin , van den Hoek Ostende Lars W. , Joniak Peter 
Published: April 2024

AbstractCentral Europe is an area of high diversity for the Talpidae (Eulipotyphla, Mammalia) during the Late Miocene. The assemblages from Slovakia (Borský Svätý Jur, Krásno, Pezinok, Šalgovce, Studienka, Triblavina) are no exception with their abundant material representing eleven species. The uropsiline Desmanella is represented by D. rietscheli and D. dubia. Desmanini fossils are attributed to Archaeodesmana vinea, Archaeodesmana dissona new species, Gerhardstorchia biradicata, and Gerhardstorchia sp. The scalopines Proscapanus minor and P. austriacus are well recorded in the Vallesian localities and support the emergence of P. austriacus before the MN9/10 transition. Talpini and Urotrichini are especially rare and only represented by Talpa cf. T. minuta and Urotrichini gen. sp. indet. Finally, we identified the youngest occurrence of Desmanodon in Europe, D. cf. D. fluegeli, at the MN9 locality of Borský Svätý Jur. The high diversity in the Late Miocene Central European is partly explained by the co-occurrence of the competing Scalopini and Talpini during the Vallesian, indicating high resource environments. The decline of these tribes, followed by the success of the desmans during the Turolian, appears as a consequence of regional environmental changes.UUID: http://zoobank.org/a3eb532b-c341-489a-b0ff-ecf3f9466a76
CANTOR’S THEOREM MAY FAIL FOR FINITARY PARTITIONS
Authors: SHEN GUOZHEN 
Published: April 2024

Abstract
A partition is finitary if all its members are finite. For a set A,

$\mathscr {B}(A)$

denotes the set of all finitary partitions of A. It is shown consistent with

$\mathsf {ZF}$

(without the axiom of choice) that there exist an infinite set A and a surjection from A onto

$\mathscr {B}(A)$

. On the other hand, we prove in

$\mathsf {ZF}$

some theorems concerning

$\mathscr {B}(A)$

for infinite sets A, among which are the following:

(1)
If there is a finitary partition of A without singleton blocks, then there are no surjections from A onto

$\mathscr {B}(A)$

and no finite-to-one functions from

$\mathscr {B}(A)$

to A.

(2)
For all

$n\in \omega $

,

$|A^n|<|\mathscr {B}(A)|$

.

(3)

$|\mathscr {B}(A)|\neq |\mathrm {seq}(A)|$

, where

$\mathrm {seq}(A)$

is the set of all finite sequences of elements of A.
Five years in: a case study of an Australian early-career secondary school music teacher
Authors: Robinson Jennifer Anne 
Published: April 2024

AbstractEarly-career secondary school music teachers navigate many challenges as they settle into the profession. These include consolidating their knowledge of subject content, gaining classroom confidence and honing skills in classroom management. In addition, their sense of belonging can be enhanced by working at collegial relationships within their faculty, across the school and feeling a part of the wider school community. These factors can elicit a ‘make or break’ response for continuing in the profession.This paper reports on a case study of an Australian early-career secondary school music teacher, in her fifth year in the profession. The case study, as a part of a larger study, sequenced quantitative and qualitative research methods, allowing insight into the music teacher’s working life and enabled the researcher to understand factors that impact daily practice. Themes explored in the study include motivation, perception of value, stress and the difficulties of securing permanent employment. The music teacher presented a positive approach to her work through her development of resilience and shared her future goals and dreams.This research offers suggestions on how schools and education authorities can best support early-career secondary school music teachers to enable them to become resilient, confident and valued practitioners for the future.
Centripetal integration of past events in hippocampal astrocytes regulated by locus coeruleus

Published: April 2024

AbstractAn essential feature of neurons is their ability to centrally integrate information from their dendrites. The activity of astrocytes, in contrast, has been described as mostly uncoordinated across cellular compartments without clear central integration. Here we report conditional integration of calcium signals in astrocytic distal processes at their soma. In the hippocampus of adult mice of both sexes, we found that global astrocytic activity, as recorded with population calcium imaging, reflected past neuronal and behavioral events on a timescale of seconds. Salient past events, indicated by pupil dilations, facilitated the propagation of calcium signals from distal processes to the soma. Centripetal propagation to the soma was reproduced by optogenetic activation of the locus coeruleus, a key regulator of arousal, and reduced by pharmacological inhibition of α1-adrenergic receptors. Together, our results suggest that astrocytes are computational units of the brain that slowly and conditionally integrate calcium signals upon behaviorally relevant events.
