description: Model-Driven Software Engineering is one way to deal with the increasing complexity of software being developed. The size and complexity of the software is also visible in the models, which are becoming larger and more complex as a result. This trend also affects the performance of model transformations, which are an important operation on these models. In the past, research has mainly focused on improving the performance of transformation engines, so there are currently no studies on how transformation developers deal with performance issues. Consequently, we conducted an exploratory mixed method study consisting of a quantitative online survey and a qualitative interview study to further investigate how developers deal with performance issues. The data set published here was generated during our study and consists of an interview guide, a code book, 13 transcribed and coded interviews and the data from the questionnaire that we collected on the interviewees.

description: Background: Geriatric patients are affected by a range of skin conditions and dermatological diseases, functional limitations and chronic diseases. Skin problems are highly prevalent in elderly populations. Aim of this study was to investigate possible associations between health, functional and cutaneous variables in aged long-term care residents. Methods: This observational, cross-sectional, descriptive prevalence study was conducted in a random sample of 10 institutional long-term care facilities in Berlin. In total, n = 223 residents were included. Demographic and functional characteristics, xerosis cutis, incontinence associated dermatitis, pressure ulcers and skin tears were assessed. Stratum corneum hydration, transepidermal water loss, skin surface pH and skin temperature were measured. Data analysis was descriptive and explorative. To explore possible bivariate associations, a correlation matrix was created. The correlation matrix was also used to detect possible collinearity in the subsequent regression analyses. Results: Mean age (n = 223) was 83.6 years, 67.7% were female. Most residents were affected by xerosis cutis (99.1%; 95% CI: 97.7% - 100.0%). The prevalence of pressure ulcers was 9.0% (95% CI: 5.0% - 13.0%), of incontinence associated dermatitis 35.4% (95% CI: 29.9% - 42.2%) and of skin tears 6.3% (95% CI: 3.2% - 9.5%). Biophysical skin parameters were not associated with overall care dependency, but with age and skin dryness. In general, skin dryness and measured skin barrier parameters were associated between arms and legs indicating similar overall skin characteristics of the residents. Conclusion: Prevalence of xerosis cutis, pressure ulcers and skin tears were high, indicating the load of these adverse skin conditions in this population. Only few associations of demographic characteristics, skin barrier impairments and the occurrence of dry skin, pressure ulcers, skin tears and incontinence-associated dermatitis have been detected, that might limit the diagnostic value of skin barrier parameters in this population. Overall, the measured skin barrier parameters seem to have limited diagnostic value for the reported skin conditions except xerosis cutis.

description: Purpose. To assess the accuracy of different methods of combining published survival curves into a summary curve that can be used in disease models or to make treatment comparisons in meta-analysis. Methods. Five methods for combining survival curves were identified: (1) iterative generalized least-squares (IGLS, Dear 94), (2) meta-analysis (MA) of failure-time data with adjustment for covariates (MFD, Hunink 94), (3) non-linear regression (NLR, Shore 90), (4) log relative risk (LRR, Voest 89), and (5) weighted LRR (w-LRR). Published survival curves were scanned into a graphical package, coordinates along each curve were identified, and required data elements were extracted semi-automatically. Two separate analyses were done: (1) each method was used to combine the survival curves from eight single arm Phase II trials of chemotherapy in 918 patients with advanced non-small cell lung cancer (NSCLC); (2) each method was used to combine the survival curves from seven randomized trials in order to reproduce a MA of chemotherapy in advanced NSCLC. I compared the resulting summary curves using the Kolmogorov-Smirnoff goodness of fit test to a "gold standard" curve calculated from the corresponding individual patient data (IPD).

description: Cyclocarya paliurus has been widely used as an ingredient in functional foods in China. However, the antioxidant properties of phenolic compounds and the effect of the plant origin remain unclear. The present study evaluated the geographical variation of this plant in term of its phenolic composition and antioxidant activities based on leaf materials collected from five regions. high-performance liquid chromatography (HPLC) analysis showed that there are three major components, quercetin-3-O-glucuronide, kaempferol-3-O-glucuronide, and kaempferol-3-O-rhamnoside, and their contents varied significantly among sampling locations. The investigated phenolic compounds showed substantial antioxidant activities, both in vitro and in vivo, with the highest capacity observed from Wufeng and Jinzhongshan. Correlation analysis revealed that quercetin and kaempferol glycosides might be responsible for the antioxidant activities. Our results indicate the importance of geographic origin, with sunny hours and temperature as the main drivers affecting the accumulation of C. paliurus phenolics and their antioxidant properties.

description: Mycobacteriophages are viruses that prey on bacteria and exploit the host's biological resources to proliferate. They have evolved extensively and are among the most common and genetically varied species on Earth. The increasing incidence of antimicrobial resistance (AMR) and the slow discovery of novel antibacterials have recently sparked a renewed interest in phage therapy.Cells can interact with one another and with their external environment as well as with other components of the cell via signal transduction pathways, which are frequently connected to changes in protein phosphorylation. The two-component system (TCS), made up of the cytosolic transcriptional response regulator (RR) and the membrane-bound sensor histidine kinase (HK) is essential for mycobacteria to identify and react to external cues. It has been demonstrated that mycobacteria's post translational modifications (PTMs) control and promote essential biological functions, including as central metabolism, and pathogenicity, but their role is not always well understood. Current mycobacteria phosphoproteomic applications have been focused on qualitative data without quantitative research. This research utilized the YemiJoy2021 lytic cluster C1 phage to infect Mycobacterium smegmatis during its mid-stationary growth phase. The study is groundbreaking in its approach, as it introduces a novel mass spectrometry (MS) protocol specifically designed for analyzing phage phosphoproteomics over time. The identification of specific phosphosites and temporal changes in phosphorylation patterns will provide valuable insights to biological mechanisms behind the anti-mycobacterial activities of mycobacteriophages. The findings of this study may influence the creation of innovative preventative techniques for mycobacterial infections and advancing precision medicine approaches in infectious disease management.

description: Nb–Mo low-alloyed steels are promising advanced high strength steels (AHSS) because of the highly dislocated bainitic ferrite microstructure conferring an excellent combination of strength and toughness. In this study, the potential of precipitation strengthening during coiling for hot-strip Nb–Mo-bearing low-carbon steels has been investigated using hot-torsion and aging tests to simulate the hot-rolling process including coiling. The obtained microstructures were characterized using electron backscatter diffraction (EBSD), highlighting the effects of Nb and Mo additions on formation and tempering of the bainitic ferrite microstructures. Further, the evolution of nanometer-sized precipitates was quantified with high-resolution transmission electron microscopy (HR-TEM). The resulting age hardening kinetics have been modelled by combining a phenomenological precipitation strengthening model with a tempering model. Analysis of the model suggests a narrower coiling temperature window to maximize the precipitation strengthening potential in bainite/ferrite high strength low-alloyed (HSLA) steels than that for conventional HSLA steels with polygonal ferrite/pearlite microstructures.

description: We explore observational and theoretical constraints on how galaxies might transition between the 'star-forming main sequence' (SFMS) and varying 'degrees of quiescence' out to z = 3. Our analysis is focused on galaxies with stellar mass M-* > 10(10) M-circle dot, and is enabled by GAMA and CANDELS observations, a semi-analytic model (SAM) of galaxy formation, and a cosmological hydrodynamical 'zoom in' simulation with momentum-driven AGN feedback. In both the observations and the SAM, transition galaxies tend to have intermediate Sersic indices, half-light radii, and surface stellar mass densities compared to star-forming and quiescent galaxies out to z = 3. We place an observational upper limit on the average population transition time-scale as a function of redshift, finding that the average high-redshift galaxy is on a 'fast track' for quenching whereas the average low-redshift galaxy is on a 'slow track' for quenching. We qualitatively identify four physical origin scenarios for transition galaxies in the SAM: oscillations on the SFMS, slow quenching, fast quenching, and rejuvenation. Quenching time-scales in both the SAM and the hydrodynamical simulation are not fast enough to reproduce the quiescent population that we observe at z similar to 3. In the SAM, we do not find a clear-cut morphological dependence of quenching time-scales, but we do predict that the mean stellar ages, cold gas fractions, SMBH (supermassive black hole) masses and halo masses of transition galaxies tend to be intermediate relative to those of star-forming and quiescent galaxies at z < 3.

description: Introduction Obliterative vasculopathy and fibrosis are hallmarks of systemic sclerosis (SSc), a severe systemic autoimmune disease. Bone marrow-derived mesenchymal stromal cells (MSCs) from SSc patients may harbor disease-specific abnormalities. We hypothesized disturbed vascular smooth muscle cell (VSMC) differentiation with increased propensity towards myofibroblast differentiation in response to SSc-microenvironment defining growth factors and determined responsible mechanisms. Methods We studied responses of multipotent MSCs from SSc-patients (SSc-MSCs) and healthy controls (H-MSCs) to long-term exposure to CTGF, b-FGF, PDGF-BB or TGF-β1. Differentiation towards VSMC and myofibroblast lineages was analyzed on phenotypic, biochemical, and functional levels. Intracellular signaling studies included analysis of TGF-β receptor regulation, SMAD, AKT, ERK1/2 and autocrine loops. Results VSMC differentiation towards both, contractile and synthetic VSMC phenotypes in response to CTGF and b-FGF was disturbed in SSc-MSCs. H-MSCs and SSc-MSCs responded equally to PDGF-BB with prototypic fibroblastic differentiation. TGF-β1 initiated myofibroblast differentiation in both cell types, yet with striking phenotypic and functional differences: In relation to H-MSC-derived myofibroblasts induced by TGF-β1, those obtained from SSc-MSCs expressed more contractile proteins, migrated towards TGF-β1, had low proliferative capacity, and secreted higher amounts of collagen paralleled by reduced MMP expression. Higher levels of TGF-β receptor 1 and enhanced canonical and noncanonical TGF-β signaling in SSc-MSCs accompanied aberrant differentiation response of SSc-MSCs in comparison to H-MSCs. Conclusions Deregulated VSMC differentiation with a shift towards myofibroblast differentiation expands the concept of disturbed endogenous regenerative capacity of MSCs from SSc patients. Disease related intrinsic hyperresponsiveness to TGF-β1 with increased collagen production may represent one responsible mechanism. Better understanding of repair barriers and harnessing beneficial differentiation processes in MSCs could widen options of autologous MSC application in SSc patients.

description: Feature modeling is widely used to systematically model features of variantrich software systems and their dependencies. By translating feature models into propositional formulas and analyzing them with solvers, a wide range of automated analyses across all phases of the software development process become possible. Most solvers only accept formulas in conjunctive normal form (CNF), so an additional transformation of feature models is often necessary. However, it is unclear whether this transformation has a noticeable impact on analyses. In this paper, we compare three transformations (i.e., distributive, Tseitin, and Plaisted-Greenbaum) for bringing feature- model formulas into CNF. We analyze which transformation can be used to correctly perform featuremodel analyses and evaluate three CNF transformation tools (i.e., FeatureIDE, KConfigReader, and Z3) on a corpus of 22 real-world feature models. Our empirical evaluation illustrates that some CNF transformations do not scale to complex feature models or even lead to wrong results for modelcounting analyses. Further, the choice of the CNF transformation can substantially influence the performance of subsequent analyses.

description: Allergene Pollen sind natürliche, biologische luftgetragene Partikel und der Hauptauslöser allergischer Atemwegserkrankungen. Die Messung allergener Pollen ist Voraussetzung für die gesundheitliche Vorsorge und zeigt Veränderungen im Pollenspektrum an, wie sie zum Beispiel im Rahmen des Klimawandels zu erwarten sind. Das in Deutschland einzige bundesweite Pollenmessnetz wird durch die Stiftung Deutscher Polleninformationsdienst (PID) betrieben. Fortbestand und Weiterentwicklung (u. a. Hybrid-System aus manuellen und automatischen Pollenfallen) dieses Messnetzes sind finanziell jedoch nicht gesichert. Im Sommer 2017 formierte sich daher der fachübergreifende Arbeitskreis "Bundesweites Pollenmonitoring", um sich über diesbezügliche Perspektiven für Deutschland auszutauschen. Für den Austausch kam der Arbeitskreis zwischen November 2017 und Juni 2018 zu drei Gesprächstagen mit jeweils unterschiedlichen Themenschwerpunkten zusammen. Die internen Protokolle zu den Gesprächstagen bildeten anschließend die Grundlage für die Erstellung des vorliegenden Positionspapiers, mit dem der Arbeitskreis seine Arbeit abschließt. Aufgrund der Bedeutung allergener Pollen für die menschliche Gesundheit und allergischer Erkrankungen für das Gesundheitssystem spricht sich der Arbeitskreis dafür aus, das bundesweite Pollenmonitoring in den Katalog staatlicher Aufgaben aufzunehmen, die der grundlegenden Versorgung der Bevölkerung mit wesentlichen Gütern und Dienstleistungen dienen (öffentliche Daseinsvorsorge). Hinsichtlich möglicher Zuständigkeiten im Rahmen der öffentlichen Daseinsvorsorge wurden im Arbeitskreis mehrere Lösungsansätze diskutiert. Unabhängig von der zukünftigen Zuständigkeit kommt der Kooperation von messtechnischen, klinischen und wissenschaftlichen Einrichtungen eine grundsätzliche Bedeutung für die adäquate gesundheitliche Vorsorge zu.

description: To find out the feasibility of different neural networks in sEMG-based force estimation, in this paper, three types of networks, namely convolutional neural network (CNN), long short-term memory (LSTM) network and their combination (C-LSTM) were applied to predict muscle force generated in static isometric elbow flexion across three different circumstances (multi-subject, subject-dependent and subject-independent). Eight healthy men were recruited for the experiments, and the results demonstrated that all the three models were applicable for force estimation, and LSTM and C-LSTM achieved better performances. Even under subject-independent situation, they maintained mean RMSE% of as low as 9.07 ± 1.29 and 8.67 ± 1.14. CNN turned out to be a worse choice, yielding a mean RMSE% of 12.13 ± 1.98. To our knowledge, this work was the first to employ CNN, LSTM and C-LSTM in sEMG-based force estimation, and the results not only prove the strength of the proposed networks, but also pointed out a potential way of achieving high accuracy in real-time, subject-independent force estimation.

description: The effect of a saturable absorber (SA) on the performance of 40 GHz optical clock signal recovered from a monolithic semiconductor laser was investigated. Optical clock recovery is the key requirement of all optical generators which are used for reducing the impairments in ultra long haul high capacity dense wavelength division multiplexing (DWDM) transmissions. It was shown that the saturable absorption in the laser cavity increases the extinction ratio and suppresses timing jitter and increases sensitivity to the data mark ratio.

description: Phthalate esters (PAEs), commonly used in food packaging materials, pose a potential health risk due to their migration into food matrices. Propolis, a resinous bee product widely consumed for its health benefits, is often packaged in plastics, raising concerns about PAE contamination. However, the occurrence of PAEs within propolis has been scarcely investigated. This study quantified PAE contamination profiles in propolis ethanolic extracts (PE) and propolis capsules (PCs) from China. The GC–MS/MS analysis of 20 PAEs demonstrated high linearity, indicating the reliability of the method. The limits of quantification (LOQ) ranged from 1.3 to 26.2 µg/kg, and the limits of detection (LOD) ranged from 0.4 to 8.6 µg/kg. Matrix effects ranged between 9% and 33%. Five PAEs were detected in PE samples: dimethyl phthalate (DMP), diethyl phthalate (DEP), diisobutyl phthalate (DiBP), dibutyl phthalate (DBP) and bis(2-ethylhexyl)phthalate (DEHP). Seventeen PAEs were detected in PC samples, with 15 consistently present in all samples (100% positivity). Diallyl phthalate (DAP), dipropyl phthalate (DPrP) and di-n-octyl phthalate (DNOP) were not detected in any sample. The total mean concentration of the 17 detected PAEs (∑17 PAEs) in the capsules ranged from 0.87 mg/kg to 23.71 mg/kg. This study found that PE and PC had the highest DBP (0.24 mg/kg) and di-heptyl phthalate (DHP: 2.29 mg/kg) levels on average, respectively. While PC showed higher PAE levels than PE. Therefore, this study provides insight into PAE contamination of raw propolis extract and encapsulated propolis.

description: Ethnic broadcasting is a unique phenomenon of multiethnic countries that could reflect and influence a country's ethnic relations. This study examines the ethnic broadcasting policies and practices in Canada and China, to determine existing issues, and reflect on the countries' ethnic relations and ethnic policies. This thesis analyzes the ethnic broadcasting operations in the two countries comparatively through interpreting with critical lenses the data collected from government and university databases. This analysis is especially interested in the relationship between ethnic relations and the broadcasting media, between ethnic policies and broadcasting policies, and between ethnic politics and ethnic broadcasting content. Several issues in the two countries' ethnic policies and ethnic broadcasting operations are revealed through the comparative analysis, particularly the insufficiency of public broadcasting presence and governmental involvement in Canadian ethnic broadcasting, and the politicization of ethnic relations and ethnic broadcasting operations in China.

description: Objective The analysis of the MR phase provides additional information on the tissue microstructure. In multiple sclerosis (MS) lesions phase alterations may reflect different stages of inflammatory activity. Here we investigated lesion morphology in MS patients with short and long disease duration on T2* weighted, phase, magnitude and susceptibility weighted imaging (SWI) at 7 Tesla (T). Methods 17 MS or clinically isolated syndrome patients with short (<60 months) and 11 with long (>60 months) disease duration underwent 7T MRI. Lesions were subsequently analyzed side-by-side with regard to morphology and visibility on T2* weighted, SWI, magnitude and SWI-filtered phase images. Results 126 of 192 T2* weighted lesions (65.6%) were characterized by a phase alteration pattern, and hence could be differentiated on phase images. In detail, a significantly reduced proportion of lesions showing phase alterations was detectable in patients with longer disease duration (mean±SD 51±37%, range 0–100%) compared to patients with short disease duration (mean±SD 90±19.5%, range 50–100%, p = 0.003). Conclusion This cross-sectional study identified different patterns of phase changes in lesions of MS patients with short and long standing disease. Longitudinal studies are warranted to prove that MR phase imaging is useful in determining the activity and the developmental stage of individual MS plaques.

description: A titanium dioxide/graphitic carbon nitride composite (TiO2/g-C3N4; TOCN) was utilized for the degradation of patulin (PAT). The introduction of carbon nitride into TOCN narrowed the band gap of titanium dioxide (TiO2), thereby enhancing the utilization of the composite with visible light. Patulin at a concentration of 250 μg/kg in aqueous solution and apple juice was degraded respectively by 100% and 85.4% under visible light. The superoxide ion (·O2-) and hydroxyl radical (·OH) play significant roles in the photocatalytic degradation of PAT, and a new degradation product was identified by ultra-high performance liquid chromatography tandem quadrupole orbitrap mass spectrometry (UPLC-Q-Orbitrap MS). In addition, photocatalytic degradation has a minor impact on the quality and nutrition of apple juice. The results of Ames and zebrafish experiments demonstrated that the toxicities of the degradation products were significantly reduced. These results indicate the TOCN photocatalyst can effectively eliminate patulin from aqueous solutions and apple juice, offering a new strategy for removing patulin from food samples.

description: Acne-like skin reactions frequently occur in patients undergoing treatment with drugs inhibiting the epidermal growth factor receptor. Recently, the effects of vitamin K1 containing cream (Reconval K1) as prophylactic skin treatment in addition to doxycycline were explored in a double-blind randomized phase II trial (EVITA) in patients with metastatic colorectal cancer receiving cetuximab. EVITA demonstrated a trend towards less severe skin rash in Reconval K1-treated patients using the tripartite WoMo skin reaction grading score as a thorough tool for quantification of drug related skin reactions. This gender-specific analysis of the EVITA trial evaluated the application of the WoMo score for assessment of epidermal growth factor receptor (EGFR)-related skin toxicities according to treatment arm and gender. To show the robustness of results parametric and non-parametric statistical analyses were conducted. All three parts of the WoMo score independently demonstrated the superiority of the treatment arm (Reconval K1) regarding a significant reduction in acneiform skin reactions in women. Men did not benefit from Reconval K1 cream at any time point in none of the WoMo score analyses. The treatment effect in women was confirmed by the use of skin rash categories based on the final WoMo overall score and mixed effect longitudinal multiple linear regression analysis. The WoMo score represents a sensitive tool for studies exploiting treatments against EGFR mediated acne-like skin rash. Part C of the WoMo score seems to be sufficient for quantification of drug related skin toxicities in further studies. Standard WoMo skin reaction score values for future studies are provided.

description: Experimental verification of the far-field radiation characteristic of reflectarrays (RAs) in the upper millimeter-wave range is challenging due to the required alignment precision given the small array dimensions. In this work, a measurement setup allowing flexible adjustment of incidence angle and distance between feed antenna and RA is presented. By means of an RA demonstrator operating at 245 GHz, the influence of alignment errors and parasitic effects, such as undesired reflections and clutter, is investigated. The resulting measured radiation pattern recorded in both principal planes exhibits excellent agreement with full-wave simulations of the corresponding RA design.

description: Today's multimedia communication has been greatly shaped by the coexistence of a number of complementary as well as competing access, delivery, and consumption technologies. Rich media are now accessible via numerous multimedia enabled devices through a wide variety of network types. "What is missing" is so far a mechanism to ensure that multimedia users can receive different qualities of video proportional to their device capabilities and network conditions. In this thesis, we propose an online adaptive video streaming concept which takes into account different issues related to the Peer-to-Peer (P2P) content distribution paradigm such as peers' unreliability, as well as pragmatic aspects like receivers' heterogeneity. Our proposal also envelops compressed-domain video adaptation, watermarking, and perceptual encryption schemes where we utilize the MPEG-21 generic Bitstream Syntax Description (gBSD) as a content metadata. The proposed architecture aims at online video adaptation with streaming in the Application Layer Multicast (ALM) overlays to serve heterogeneous devices including small handhelds. In this proposed design, participating peers act as the stream source, adaptation engine, and perform the streaming tasks. We implemented a 3-in-1 adaptation-watermarking-encryption system to evaluate the compressed-domain adaptation performance. For the adaptive streaming, simulation is used to manifest that our design is robust, reliable, and suitable for multi-participant real-time collaboration and real-life deployment. The adaptive streaming system performance is also validated with the results found from an analytical model.
On the nature of expertise in family therapy

description: Background: While family therapy has been demonstrated to be an effective intervention, practitioners in the field face a number of challenges that provide the impetus for this project. Therapists commonly report feeling confused by the theoretical debates and the demands placed on them by empirically supported treatments, and there is also significant variability between clinicians in quality of practice and within their individual practice. While the therapist variable is consistently recognised as the most robust predictor of outcomes, there is a paucity of research on how this variable exemplifies skilled performance and expertise, and gaps in understanding of the therapist's contribution to therapeutic change. Method: This investigation examines elite practice to develop an understanding of the perceptual-affective-cognitive mechanisms underpinning the habits of mind, which mediate expertise in the naturalistic practice of family therapy. Two in-depth studies were used; the first investigating procedural knowledge and the second focusing on the dynamic thinking process. Six novice and seven elite family therapists contributed narratives of complex and straightforward cases in Study 1, and narratives of in-themoment mental events while conducting family therapy (using video assisted recall) in Study 2. The case narratives were analysed using modified grounded theory and open coding, with each study generating four categories of mental events associated with good practice. A novice and elite practitioner comparison of these categories was then conducted to find patterns of convergence within and divergence between the groups. Results: The study of procedural knowledge identified four categories of habits of mind mediating expertise; a) Mental preparation; b) Deliberate monitoring; c) Quality of engagements; d) Using emotions and managing the emotional climate. The study of dynamic thinking processes generated four categories of in-the-moment perceptualaffective- cognitive mental activity; a) Therapy as a balancing act; b) Sensing relationships; c) Noticing and promoting micro-changes; d) Engaging in reflection and evaluation. Elite practitioners demonstrated high convergence in all these categories, while novices exhibited higher variability and less consistency. Conclusion: Relational-emotional expertise, clinical expertise and reflective practices emerged as over-arching features of expertise in family therapy. Some novices demonstrated some of the elite-like mental processes and, like elite practitioners, engaged in high levels of self-reflection and meta reflective practices, generated family specific mental models that linked the relational process with clinical symptoms, and established an emotional place in the matrix of relationships. The elite practitioners developed an emotional-intuitive understanding, and used relational-clinical practices to facilitate changes in collaboration with their client-family.

description: The intake of seven sweeteners (acesulfame K, aspartame, cyclamates, saccharins, steviol glycosides, sucralose (all chronic intake) and erythritol (acute intake)) via foods and beverages by the Dutch population was assessed in a refined assessment using branded data (product labels, use levels and consumption shares of brands) and scenarios for brand-loyalty. In general, the intake of these sweeteners was below their respective health-based guidance values (HBGVs). Only for toddlers high intakes of acesulfame K, cyclamates and erythritol were around or slightly above the HBGV in the most conservative scenario ('full brand-loyalty, consumers only'). However, intake of all sweeteners was likely overestimated due to conservative assumptions when data on the presence of sweeteners were absent. Improved information, particularly on products with a high contribution to the sweetener intake in toddlers, is needed to further refine the intake assessment. In conclusion, the intake of all sweeteners via foods and beverages is most likely of no concern for the Dutch population.
