Nano-ridge plasmonic structural colors fabricated by roll-to-roll hot-embossing
Authors: Wu Peijin , Chen Shenghua , Lin Weiqiang , Zheng Jun , Sheng Zhengming , Ye Zhicheng
Published: November 2024

Structural colors are now applied in many areas, like traceable anti-counterfeiting and wearable technologies, due to their durability and wide color gamut. However, the large-scale deployment of structural colors has been limited by the complexity of device structures and, subsequently, the realization of cost-effective fabrication. In this work, we introduce a plasmonic structural color based on periodical nano-ridges, which can be nano-imprinted on an aluminum-polyurethane-polyethylene terephthalate film. These aluminum nano-ridges can excite metal and dielectric hybrid waveguide modes with surface plasmonic resonance for transverse magnetic (TM) lights, resulting in broad dips in the reflection spectrum. The design and key optical features of the proposed device structures are presented. The fabricated structures show desirable features, including angle-dependent and polarization-dependent chromatic reflections. This structure could be mass-produced using a conventional roll-to-roll hot-embossing nano-imprinting process on pre-prepared films, making it suitable for low-cost anti-counterfeiting applications.

Authors: Liu Xiaojuan , Jiang Xiwen , Liu Tianrun , Xu Yan , Zhang Wenfei
Published: November 2024

Taking advantage of both the saturable absorption and high third-order nonlinear properties of the carbon quantum dots (CQDs) saturable absorber (SA), conventional soliton (CS) mode-locking, fundamental mode-locking, and 20th harmonic mode-locking of an erbium-doped fiber (EDF) laser are achieved. First, CQDs are prepared by solvothermal method. Then, taper-fiber-structured CQDs-SA and sandwich-structured CQDs-SA are fabricated. Investigated by a balanced twin-detector measurement scheme, the SA devices exhibit excellent nonlinear saturable absorption properties (NSAP) at the wavelength of 1.55 µm. Second, mode-locked by the as-prepared taper-fiber-structured CQDs-SA, CS mode-locking with central wavelength and pulse width of 1561.5 nm and 675 fs is achieved. When sandwich-structured CQDs-SA is integrated, a fundamental mode-locking as well as 20th harmonic mode-locking (HML) are realized. The fundamental repetition rate is 4.93 MHz with a pulse duration of 1.18 ps. In the 20th HML operation, the repetition rate is 98.6 MHz and the pulse duration is 1.33 ps. The results provide the first demonstration of the simultaneous applications of both high nonlinear and saturable absorption effects of the CQDs, as well as broaden new avenues and opportunities for extending the methods of realizing ultrafast photonic devices.
Evaluation of fluorometrically-derived Chlorophyll a as a satellite ocean color validation product using statistical metrics
Authors: Neeley Aimee , Cetinic Ivona , Thomas Crystal
Published: November 2024

The fluorescence of Chlorophyll a (Chla) has long been considered a reliable estimate of phytoplankton biomass in aquatic environments. The in vitro fluorometric method for measuring Chla is a simple, fast, and cost-effective way to estimate phytoplankton biomass. High performance liquid chromatography (HPLC) measurements of Chla have been used historically for ocean color validation. The applicability of fluorometrically - derived Chla (FChla) to satellite ocean color validation has not been fully evaluated. To this end, we developed statistical metrics to evaluate the uncertainty of fluorometric estimates of Chla by comparing to coincident measurements made by HPLC. Further analyses on the distribution of uncertainties demonstrates occasional trends in the discrepancies between FChla and HChla, enabled the development of a set of recommendations for future collection and validation efforts.

Authors: Costa Eudes Antônio , De Carvalho Fernando Soares
Published: November 2024

Neste trabalho, definimos uma sequência de polinômios associada à sequência numérica repunidade. Isto envolve estender o conceito de sequência repunidade, uma sequência do tipo Horadam, representada pela sequência de números repunidades, em que rₙ  representa o n-ésima repunidade, e a relação de recorrência: rₙ₊₁ = 11rₙ-10rₙ₋₁, com r₀ = 0, r₁ = 1, para n ≥ 1. Neste artigo, investigamos esta nova sequência polinomial em detalhe e apresentamos alguns resultados e aplicações derivados desta investigação. Por exemplo, estudamos a equação caraterística e derivamos a função geradora correspondente. Adicionalmente, analisamos a relação de recorrência associada à soma de n polinômios repunidades.

„Zwierciadło i zwierzyniec pana Mikołaja Reja”, czyli słów kilka o japońskim odkrywaniu literatury polskiej
Authors: Splisgart Tomomi
Published: November 2024

Despite the rise in availability, Polish literature is viewed in Japan as exotic and unavailable. An attempt to fill this gap is being undertaken by Tokimasa Sekiguchi who familiarises the Japanese readers with selected aspects of Mikołaj Rej’s writing in an original work entitled Zwierciadło i zwierzyniec pana Mikołaja Reja (Mirror and Preserve by Mr. Mikołaj Rej), published in 2021 in Tokyo. In the course of the book, the author presents carefully selected works by the Polish poet and prose writer of the Renaissance period, complementing the respective fragments with commentary and references to both the history of Poland and the Japanese context. Tokimasa Sekiguchi’s text constitutes a significant contribution to the understanding of Polish culture and history in the land of cherry blossoms.
„Przeczuwał o wiele późniejszą teorię Hipolita Taine’a…”? Piotr Chmielowski o postawie krytycznoliterackiej Maurycego Mochnackiego
Authors: Krysowski Olaf
Published: November 2024

Piotr Chmielowski considered Maurycy Mochnacki’s attitude in literary criticism as an expression of the 19th-century culture viewed as a diverse, dynamic and ever-changing whole which had a number of consistent characteristics that helped define it. Mochnacki was incorporated into the discourse concerning the 19th century, so in a sense on modernity as well, because the experience of modernity was what characterised the rapidly-developing civilisation of the 19th century. For Chmielowski, this modernity was personified by Hippolyte Taine, a positivist and philosopher, whose theory was supposedly predicted in one way or another by Mochnacki. The point is not about the correctness of Chmielowski’s diagnosis as it can be questioned, discussed and rejected. It is about the fact that Mochnacki, especially from the point of view of his domestic activity (before the November Uprising) could have been perceived in the 19th century and could still be today, as a literary critic and opinion journalist who was thoroughly modern in his own time.
O Bałtyku, polskiej wsi oraz edukacji na dwa głosy: Stanisław Pigoń i Bernard Chrzanowski
Authors: Nowicka Elżbieta
Published: November 2024

The article constitutes a commentary on the “common spaces” in the writings of Stanisław Pigoń and Bernard Chrzanowski (Chrzanowski: a social and education activist living in Greater Poland at the turn of the 20th century). They represented different generations and came from different social environments. Pigoń and Chrzanowski most likely met during Pigoń’s stay in Poznań; before that, they knew each other’s texts, which expressed similar conviction on the significance of the Baltic Sea for Polish culture and the future Polish state. Since the regaining of independence, they devoted significant attention to the rural areas and the education of their inhabitants. The tasks they set in this area for the intelligentsia can be placed on the axis of the so-called “intelligentsia’s revision literature” which spanned a few generations in Poland.
The work organization in teleoperated driving – a human reliability and socio-technical systems perspective
Authors: Grabbe Niklas , Brettschneider Stefan , Bengler Klaus
Published: November 2024

Very high levels of automation in road traffic are accompanied by the need for teleoperation. If the driverless autonomous vehicle is not able to solve a complex driving situation, then the problem should be solved by a teleoperated intervention by getting a human into the loop. Such a system is highly complex, interacting in a socio-technical system. Therefore, in addition to the empirical research of user-centered development of teleoperated driving, an analytical and systemic approach is crucial in the first place to understand the interrelationships between the subsystems and to optimize a teleoperated driving system. This work provides a base for the systemic consideration by taking two different perspectives focusing on the work organization and vehicle operation dealing with how many vehicles can be monitored and serviced by one operator. First, a brief analytical perspective of human reliability is taken, emphasizing the appropriate definition of the operational design domain and knowledge of its variability. Second, a comprehensive systemic, socio-technical perspective is applied using the functional resonance analysis method (FRAM) for a reflexive and computational purpose highlighting effects on operator workload and traffic performance. Finally, the implications of the research results are discussed and integrated into socio-technical interactions in everyday teleoperated driving between blunt- and sharp-end factors from a safety and reliability perspective to demonstrate the complex leverage of the work organization. Overall, the insights contribute to an enhanced understanding of the complex socio-technical interactions in teleoperated driving.

Published: November 2024

Systemic lupus erythematosus (SLE) poses a diagnostic challenge due to its heterogeneity. This study examines the cardiac complications of SLE comprehensively, covering pericarditis, myocarditis, pleural effusion, valvular disease, atherosclerosis, and cardiac arrhythmias. Nearly one-third of SLE-related deaths are attributed to cardiovascular diseases, necessitating a deeper understanding of cardiac pathophysiology. The impact of SLE on the cardiovascular system manifests in various ways, including recurrent and resistant pericarditis, severe myocarditis, and pleural effusion. Valvular diseases, atherosclerosis, and cardiac arrhythmias are prevalent, with immune complex deposition playing a role in atherosclerosis. Diagnostic criteria involve clinical features, laboratory findings, and autoantibodies, emphasizing the need for early diagnosis and a multidisciplinary diagnostic approach. The review explores pharmacological and non-pharmacological modalities for managing cardiac manifestations in SLE. Recommendations include NSAIDs, colchicine, and proton pump inhibitors for acute pericarditis, while selective immunosuppressive therapy is emerging for myocarditis. Valvular diseases require individualized treatment approaches, and careful corticosteroid management is crucial to avoid increased cardiovascular events. Anti-malarial therapy, particularly hydroxychloroquine, shows promise in mitigating cardiovascular risk factors. Non-pharmacological modifications, such as diet, exercise, and smoke cessation, significantly contribute to cardiovascular health in SLE patients. Adjuvant therapies involving glutathione and glutathione peroxidase focus on redox balance, offering potential interventions. This integrated approach combines diagnostic insights with diverse treatment modalities, providing a holistic strategy for managing cardiac complications in SLE. Ongoing research is essential to refine these strategies and optimize individualized treatment plans for improved patient outcomes.
Performance evaluation of enzymatic total bile acid (TBA) routine assays: systematic comparison of five fifth-generation TBA cycling methods and their individual bile acid recovery from HPLC-MS/MS reference
Authors: Grimmler Matthias , Frömel Tobias , Masetto Angelique , Müller Holger , Leber Tina , Peter Christoph
Published: November 2024

Objectives

Serum total bile acid (TBA) levels are frequently assessed in clinical routine for the early detection of hepatobiliary dysfunction. However, the comparability of current 5th-generation TBA cycle assays based on 3α-hydroxysteroid dehydrogenase (3α-HSD) and their ability to quantify individual bile acids has not been systematically addressed.

Methods

Patient serum samples (n=60) across the diagnostically relevant TBA range (1–200 μmol/L) were analyzed using five TBA routine assays from Abbott, DiaSys, Diazyme, Beijing Strong (BSBE) and Randox on the same analyzer (BioMajesty® JCA-BM6010/C). The assays were compared using Passing-Bablok regression and the recovery of 11 individual BAs was evaluated against RP-HPLC-MS/MS as non-enzymatic reference method.

Results

Despite excellent correlation (Spearman r ≥0.99), the assays showed proportional differences (slope) ranging from 0.99 (BSBE/Randox) to 1.24 (Abbott/DiaSys). The assays showed considerable deviation in the recovery of competitor’s calibrators and controls, and large heterogeneity in the recovery of individual BAs, with mean deviations from reference value between 13 % (DiaSys) and 42 % (Abbott). CA and TCA were measured most accurately and consistently, whereas GCA, CDCA, DCA, UDCA, and conjugates were over- or undermeasured to varying degrees.

Conclusions

The linear relationship and constant proportional bias between all five routine assays enable the harmonization of TBA measurements up to 60 μmol/L. However, for patient samples with high TBA levels and disease-specific overrepresentation of individual BAs, harmonization will require: i) optimized reaction conditions to equalize substrate specificity, and ii) calibration to a common, commutable reference material with well-defined BA composition instead of internal standards spiked with different BAs.

Authors: Maharjan Anu S. , Amjadi Sogol S. , Jaskowski Troy D. , La’ulu Sonia L. , Lebiedz-Odrobina Dorota , Frech Tracy M. , Tebo Anne E.
Published: November 2024

Objectives

This study aimed to determine the clinical significance of Krebs von den Lungen-6 (KL-6), surfactant proteins A (SP-A) and D (SP-D) in the evaluation and management of interstitial lung disease (ILD).

Methods

Serum KL-6, SP-A, SP-D levels were measured in 122 unique consecutive patients referred for connective tissue disease (CTD) associated ILD (CTD-ILD) autoantibodies and 120 “healthy” controls. Patients’ charts were retrospectively reviewed and categorized as ILD and non-ILD or CTD-ILD and other ILD. All biomarkers were evaluated for diagnosis and moderate vs. severe ILD based on high-resolution computed tomography (HRCT).

Results

ILD was diagnosed in 52 % (n=64) and non-ILD in 48 % (n=58). ILD patients were categorized as other ILD (61 %, n=39) or CTD-ILD (39 %, n=25). Patients with ILD had significantly elevated levels of SP-A (p<0.02), KL-6 or SP-D (both p<0.0001) when compared to those with non-ILD. The mean levels of all biomarkers were significantly elevated levels in the ILD compared to non-ILD group (p<0.0001). No significant difference in biomarker levels between CTD-ILD and other ILD groups (p≥0.900). Biomarkers had comparable specificities (89–93 %) however; sensitivities were variable at 75 , 77 and 17 % for KL-6, SP-D and SP-A, respectively. Combination of KL-6 and SP-D yielded comparable diagnostic accuracy to all biomarkers with median levels significantly higher in patients with severe vs. mild disease.

Conclusions

KL-6 and SP-D levels are elevated in ILD and therefore contribute to the diagnosis and risk stratification for patient management.
Solving the crisis with “do-it-yourself heroes”? The media coverage on pioneer communities, Covid-19, and technological solutionism
Authors: Asmuss Jeanette , Hepp Andreas , Lüpkes Julie , Schmitz Anne
Published: November 2024

Protective shields and medical devices produced in Makerspaces as well as the early detection of disease through self-measurement have been widely publicized in the media coverage of the Covid-19 pandemic. This article systematically examines this phenomenon by analyzing the coverage of the Maker and Quantified Self movements in Germany and the UK. Through a discourse analysis of (online) newspapers, the article demonstrates that during the pandemic the coverage of both pioneer communities was markedly positive. Makers were often portrayed as problem solvers, while Quantified Self members were depicted as seismographs of the pandemic. Overall, our analysis reveals an overarching narrative that constructs members of these groups as “do-it-yourself heroes” who respond to the Covid-19 pandemic through their experimental practices, promoting a form of technological solutionism.
A Schmidt–Nochka theorem for closed subschemes in subgeneral position
Authors: Heier Gordon , Levin Aaron
Published: November 2024

In previous work, the authors established a generalized version of Schmidt’s subspace theorem for closed subschemes in general position in terms of Seshadri constants.
We extend our theorem to weighted sums involving closed subschemes in subgeneral position, providing a joint generalization of Schmidt’s theorem with seminal inequalities of Nochka.
A key aspect of the proof is the use of a lower bound for Seshadri constants of intersections from algebraic geometry, as well as a generalized Chebyshev inequality.
As an application, we extend inequalities of Nochka and Ru–Wong from hyperplanes in 𝑚-subgeneral position to hypersurfaces in 𝑚-subgeneral position in projective space, proving a sharp result in dimensions 2 and 3, and coming within a factor of

of a sharp inequality in all dimensions.
We state analogous results in Nevanlinna theory generalizing the second main theorem and Nochka’s theorem (Cartan’s conjecture).

Comparison between thermal models across the Middle Magdalena Valley, Eastern Cordillera, and Eastern Llanos basins in Colombia
Authors: Bermúdez Mauricio A. , Moreno Gleubis Belén Silveira , Fernández Andrea Gómez , González Natalia Urrea , Chaparro Lady Alejandra Barrera
Published: November 2024

In this research, we compared thermochronological and traditional one-dimensional thermal models across the Middle Magdalena Valley (MMV), Eastern Cordillera, and Eastern Llanos Basins in Colombia. These models allow us to relate cooling/heating histories to exhumation events, subsidence, fault activities, and fluid flow. The Eastern Cordillera and Eastern Llanos Basins are discriminated as prospective zones for hydrocarbon (HC) generation. The De Armas Syncline at the MMV basin shows high thermal maturity (127°C), describing rocks completely depleted in terms of HC generation. The eastern zone of this syncline is buried until it reaches temperatures above 150°C. The contrast between thermal models in the Eastern Cordillera basin suggests a possible sediment supply scenario from the west to the east of the Soapaga Fault. In the Eastern Llanos basin, the thermal histories between both models explain the latest uplift and sediment supply processes from the hinterland zone of the Eastern Cordillera to the foothill zone of the Eastern Llanos basin. In terms of thermal evolution, the three basins are different, reaching different levels of burial and HC maturity. However, in terms of cooling events related to exhumation, the basins have similarities as they are controlled by the mountain building of the Eastern Cordillera of Colombia.
Thermal conductivity evaluation of magnetized non-Newtonian nanofluid and dusty particles with thermal radiation
Authors: Hussain Syed Modassir , Khan Umair , Obalalu Adebowale Martins , Zaib Aurang
Published: November 2024

The thermal conductivity of nanofluids (NFs) has emerged as a critical area of research due to its potential to enhance heat transfer in various industrial applications. Non-Newtonian NFs, in particular, exhibit unique flow characteristics under the influence of magnetic fields, making them suitable for systems requiring precise control of fluid dynamics, such as cooling systems in electronics and energy sectors. Owing to its usage, this article presents the magneto-Marangoni convective flow for fluid (phase-I), particle (phase-II), and propagation in tangent hyperbolic NF (copper–ethanol) containing maximum cell swimming speed. This study aims to evaluate the thermal conductivity of magnetized non-Newtonian NFs mixed with dusty particles in the presence of thermal radiation, exploring how magnetic fields and particle interactions affect overall thermal performance. The Gegenbauer wavelet collocation-based scheme was utilized to solve the model and investigate physical attributes such as plate friction, Nusselt number, Sherwood number, and mass flux. The results indicate that the species reaction field is increased by activation energy, whereas it is reduced by chemical reaction. Also, increasing values of thermal radiation tend to improve the heat distribution.
40 Gb/s RoFSO communication system under turbulent channel link for 5G applications
Authors: Mohammed Tahani J. , Ali Mazin Ali A.
Published: November 2024

The present study involves an examination of a communication system known as radio over free space optics (RoFSO), which was designed using Optisystem ver. 20. The main purpose of this inquiry is to analyze the transmission of data at a rate of 40 Gb/s over a link distance of 2 km. The achievement was attained by the utilization of four transmission channels, each of which has the capability to send data at a rate of 10 Gb/s. The system under consideration was evaluated through varying degrees of turbulence. Two scintillation models, log-normal and gamma–gamma, were used to evaluate the proposed communication performance and include evaluating the behavior of specific wavelengths (193.1, 193.2, 193.3, and 193.4 THz) in transmitting data. This evaluation is achieved by the metrics Q-factor, bit error rate (BER), and log BER. The suggested system’s data-transfer performance improved up to a distance of 1.75 km when the scintillation (L-N) model was applied, whereas it was limited to 0.75 km when the (G-G) model was imposed. Furthermore, it is noticed that the wavelength (193.1 THz) is distinct in data transfer across the two models, followed by the wavelength (193.4 THz). RoFSO is an emerging network architecture that holds significant potential for fulfilling the envisioned requirements for the advancement of 5G systems.

Elbow injuries in overhead throwing athletes: clinical evaluation, treatment, and osteopathic considerations
Authors: King Benjamin W. , Raum George M. , De Luigi Arthur J. , Bowers Robert L.
Published: November 2024

Injury to the elbow is very common in the throwing athlete and can potentially lead to long absences from play and, in the most severe scenarios, medical retirement. The throwing motion is a highly complex series of movements through the entire kinetic chain that results in very high angular velocities and valgus forces at the elbow joint. The repetitive nature of overhead throwing in combination with the high levels of accumulated force at the elbow puts both pediatric and adult athletes at risk of both acute and chronic overuse injuries of the elbow. This review provides an update on common injuries in the throwing athlete and covers clinical presentation, diagnosis, and treatment of these injuries.

Authors: Magdy Rofaida M. , Dolins Karen Reznik , Nagdy Hanan , Ali Tasneem Mohammed , Elabd Heba S. , Hassan Mohammad Ahmad
Published: November 2024

Objectives

Maple syrup urine disease (MSUD) is considered one of the intoxication-type inborn errors of metabolism (IT-IEM). Patients with MSUD are afflicted with a chronic illness, and the disease and its management have both physical and psychological consequences for the patients and their families. The aim of this study was to assess the quality of life (QoL) and its main determining factors for patients with MSUD and their families under follow-up in Sohag University Hospital.

Methods

Parents of 36 patients with MSUD participated in a questionnaire translated into Arabic to assess their QoL. Subsequently, a file review was conducted to identify any key factors that could potentially influence the parents’ QoL.

Results

The results of the study indicated that 27 (75 %) of the MSUD patients exhibited poor QoL, while only 9 (25 %) patients reported good QoL across all studied aspects. Significant differences were observed between the two groups in terms of the disease onset, whether acute or asymptomatic (diagnosed before acute metabolic decompensation) (p=0.001) and the type of screening employed (p=0.007).

Conclusions

There is a paucity of data on the QoL of pediatric patients with IT-IEM, including MSUD. The methodological approaches and assessment instruments utilized in existing studies are inconsistent. Identifying the factors that affect QoL would be beneficial for improving patient care, evaluating outcomes and treatments, and planning effective social and psychological interventions to enhance the patients’ QoL.
Prevalence of fragile X syndrome in South Asia, and importance of diagnosis
Authors: Fazna Aminath , Hagerman Randi Jenssen
Published: November 2024

Fragile X syndrome (FXS) is a genetic disorder caused by a mutation in the FMR1 gene on the X chromosome, leading to a range of developmental and intellectual disabilities. FXS is characterized by intellectual disability, behavior challenges, and distinct physical features such as an elongated face, large ears, and hyperflexible joints; FXS remains the most common inherited cause of intellectual disability. Behavioral manifestations often include attention deficits, hyperactivity, anxiety, and features of autism spectrum disorder. The prevalence of FXS in the South Asian population is not well-documented, but existing studies suggest it may be comparable to global prevalence rates, which are approximately 1 in 4,000 males and 1 in 8,000 females. Accurate diagnosis of FXS in South Asians is crucial due to the implications for early intervention and treatment, which can significantly improve the quality of life and developmental outcomes for affected individuals. Early diagnosis also facilitates genetic counselling and family planning, helping to reduce the risk of recurrence in families. Increased awareness and screening in South Asian communities are essential to address the diagnostic gap and ensure timely support for individuals with FXS or disorders associated with the premutation of FMR1.
Considerations for electromagnetic simulations for a quantitative correlation of optical spectroscopy and electron tomography of plasmonic nanoparticles

Published: November 2024

The optical cross sections of plasmonic nanoparticles are intricately linked to their morphologies. Accurately capturing this link could allow determination of particles’ shapes from their optical cross sections alone. Electromagnetic simulations bridge morphology and optical properties, provided they are sufficiently accurate. This study examines key factors affecting simulation precision, comparing common methods and detailing the impacts of meshing accuracy, dielectric function selection, and substrate inclusion within the boundary element method. To support the method’s complex parameterization, we develop a workflow incorporating reconstruction, meshing, and mesh simplification, to enable the use of electron tomography data. We analyze how choices of reconstruction algorithm and image segmentation affect simulated optical cross sections, relating these to shape errors minimized during data processing. Optimal results are obtained using the total variation minimization (TVM) reconstruction method with Otsu thresholding and light smoothing, ensuring reliable, watertight surface meshes through the marching cubes algorithm, even for complex shapes.

Comparing classic time series models and state-of-the-art time series neural networks for forecasting as-fired liquor properties
Authors: Ng Jerry , Lawryshyn Yuri , DeMartini Nikolai
Published: November 2024

The properties of as-fired black liquor dictate kraft recovery boiler operation. If these properties could be forecasted, operations could be adjusted to optimize boiler performance. Here, we compare the performances of classic time series models and two state-of-the-art time series neural networks for forecasting as-fired liquor heating value, viscosity, and boiling point rise at a Canadian mill. Additionally, we show that, like classic time series models, autoregressive neural networks can be regarded as functions of unknown disturbances, which is useful in comparing model complexities. Our results show that classic time series models can accurately forecast as-fired liquor properties and that classic time series models perform comparably to state-of-the-art time series neural networks. We suspect this is due to the high autocorrelation of mill data that results from frequent measurements relative to long residence times. This autocorrelation is suspected to attenuate the cross-correlations between upstream disturbances and as-fired liquor properties. As a result, neural networks, which are useful for accommodating non-linear cross-correlations and dynamics, struggle to outperform classic time series models and may not always be appropriate for forecasting chemical process parameters.
Zur Bedeutung der Leitlinienerstellung für den Öffentlichen Gesundheitsdienst zur effizienten Überwachung der Trinkwasserversorgung für die Bevölkerung

Published: November 2024

Die Trinkwasserüberwachung ist eine originäre Aufgabe des Öffentlichen Gesundheitsdienst (ÖGD). Sie dient dem Schutz der öffentlichen Gesundheit. Für diese Aufgabe sind internationale und nationale Normen und Handlungsempfehlungen etabliert. Zugleich bestehen Ausgestaltungslücken und es fehlen Überwachungskapazitäten im ÖGD. Lücken zu schließen, und Kompetenzen und Kapazitäten für die Trinkwasserüberwachung im ÖGD zu stärken ist in Anbetracht aktueller ökologischer und geopolitischer Herausforderungen besonders dringend.
Evidenzbasierung im Infektionsschutz
Authors: Harder Thomas , Bornhofen Bernhard , Rexroth Ute
Published: November 2024

Wie das Beispiel der STIKO-Empfehlungen zeigt, sichert ein evidenzbasiertes, transparentes und partizipatives Vorgehen bei der Entwicklung von Empfehlungen die Qualität der Maßnahmen im Infektionsschutz und erhöht deren Akzeptanz bei den Zielgruppen. Neben zeit- und ressourcensparenden Methoden wie Rapid Reviews und KI-Anwendungen braucht der ÖGD jedoch strukturelle Ertüchtigung, um im Infektionsschutz sein wissenschaftliches Selbstverständnis und Evidenzbasierung noch breiter umzusetzen.

The green and eco-friendly synthesis of gold nanoparticles (AuNPs) from renewable resources such as plants, algae, fungi, and bacteria has recently gained interest due to its use of sustainable feedstocks. This review presents an in-depth exploration of AuNP synthesis methods and their applications in cancer imaging and therapy. We examine the mechanisms behind various physical and chemical techniques used to synthesize AuNPs, with a special focus on the unique biomedical applications of green-synthesized AuNPs in diagnostic and therapeutic platforms, such as imaging and targeted therapy. Although promising, green synthesis of AuNPs faces challenges, including variability in particle size, limitations in morphology control, and scalability issues, which need to be addressed to fully harness their potential. This review also demonstrates that AuNPs can be loaded with anticancer agents to create targeted drug delivery vehicles for tumor treatment. As nanotechnology drives revolutionary advances in healthcare, AuNPs offer a promising toolkit for medical progress. However, a fundamental understanding of AuNPs and rigorous risk assessments in diagnostics, imaging, and therapeutic applications are essential to enable their safe and effective use in clinical settings.
