Semiconductor Enhanced rGO/Ag0/ZnO Ternary Hybrid Revealing Charge Transfer Enhancement in SERS Detection of Raman Reporter Molecules
Authors: Chundekatt Ummer Fadeela , Kalarikkal Nandakumar 
Published: January 2024

AbstractIn this work, we have investigated the role of the chemical enhancement mechanism in SERS detection on a ternary hybrid substrate fabricated by incorporating ZnO nanostructures into an in situ synthesized reduced graphene oxide/silver composite. The sensing performance of the ternary substrate at various ZnO concentrations is investigated using Raman reporter molecules (RRM) such as Rhodamine 6G and 4‐Mercaptobenzoic acid. The SERS signals show enhancement by adding varied amounts of ZnO, revealing a new way of SERS enhancement by incorporating semiconductor nanostructures rather than conventional hotspot engineering. To probe chemical enhancement, we kept the electromagnetic contribution constant by keeping the same concentration of Ag in all the substrates investigated in this study. The obtained enhanced SERS signals of the probe molecules reveal the contribution from the chemical enhancement mechanism with the addition of ZnO. This vital observation reveals a new gateway in the field of SERS detection for developing a semiconductor‐enhanced, economical, and sustainable SERS substrate.

Published: January 2024

AbstractWe present an innovative Z‐scheme photocatalytic system, TiO2/Ag−Pd/Cd0.8Zn0.2S, exhibiting remarkable stability in aqueous solutions containing benzyl alcohol/acetic acid. Its performance rivals that of the benchmark Z‐scheme catalyst, ZnO/Pt/Cd0.8Zn0.2S. Thorough characterizations were performed using XRD, XPS, TEM, and UV‐Vis techniques, examining both the entire Z‐scheme system and its individual components, namely Ag−Pd/TiO2 and Cd0.8Zn0.2S. The standout performer, TiO2/Ag−Pd/Cd0.8Zn0.2S, demonstrated an apparent quantum yield (AQE) of 7 % within the 350–650 nm range. In contrast, AQEs for Ag−Pd/TiO2 and Cd0.8Zn0.2S were 0.6 % and 2.1 %, respectively, under identical conditions. Furthermore, we propose a charge transfer mechanism supported by femtosecond transient absorption spectroscopy (FTAS). This investigation not only introduces a stable Z‐scheme system with superior photocatalytic hydrogen production capabilities but also advances the FTAS technique for mechanistic exploration. In essence, our research paves the way for more efficient metal oxide/metal/Cd(Zn)S hybrid systems in the realm of photocatalysis.

Published: January 2024

AbstractIn this study, p(CTP‐co‐MMCA) microparticles, a novel cyclomatrix polyphosphazene, were synthesized. Among the p(CTP‐co‐MMCA) polymeric structures, p(CTP‐co‐MMCA) (1 : 3) with a high surface amine group was found to be in the form of microparticles after detailed structural and morphological characterization. These microparticles were modified with Au0 and Ag0 nanoparticles using two different green reductants. The antimicrobial activities of p(CTP‐co‐MMCA) microparticles and their Au0 and Ag0 composites against P.Aeruginosa ATCC 27853, S.Aureus ATCC 6538 and C.Albicans were investigated. Metal composites were found to have better antimicrobial activity. Cyclomatrix p(CTP‐co‐MMCA) microparticles with antimicrobial properties and their Au0 and Ag0 composites were also used for the release of Ceftriaxone sodium and RNA. Cyclomatrix p(CTP‐co‐MMCA) microparticles and its Au0 and Ag0 composites retained 48.21±5.34 mg/g, 49.36±6.95 mg/g and 23.95±6.45 mg/g ceftriaxone sodium, respectively, while they retained 79.15±6.85 mg/g, 47.49±6.24 mg/g and 57.47±9.48 mg/g RNA, respectively. Release studies revealed that the presence of Au0 and Ag0 nanoparticles imparted a slower release behavior to p(CTP‐co‐MMCA) microparticles. The release studies revealed that the presence of Au0 and Ag0 nanoparticles imparted a slower release behavior to the p(CTP‐co‐MMCA) microparticles.

AbstractThe Buchwald–Hartwig cross‐coupling reaction of 3‐bromo‐4‐indolylmaleimide with various anilines, aminopyridines and amides is described. A wide variety of 3‐amino‐4‐indolylmaleimides and 3‐amido‐4‐indolylmaleimides was prepared in good to excellent yields.

Authors: Borowicz Richardson Anja , Papuc Oana Teodora 
Published: January 2024

AbstractThis chapter explores the practice of neuroaesthetics research, highlighting its collaborative nature and its applications in both artistic and academic settings. It proposes problem-based learning (PBL) as a suitable technique for neuroaesthetics research, emphasising its value in transforming researchers' perspectives and interactions. The benefits and challenges of using PBL are examined in the context of collaborative artistic projects, as well as in the classroom and Humanities research. The chapter also addresses emerging issues concerning copyrights, ethics, and permissions in PBL collaborations.Overall, the authors provide general considerations on PBL usage that will appeal to both specialists and non-specialists in the field. They present the technique of problem-based learning as essentially suited for neuroaesthetics research and point out the value of PBL principles in terms of lifestyles and social habits.
Deep Mining Authorship
Authors: Manninger Sandra , del Campo Matias 
Published: January 2024

AbstractConsidering the emerging field of architecture and artificial intelligence, it might be necessary to contemplate the remodeling of the concept of authorship entirely. The invention of authorship is a complex historical process that can be traced back to the emergence of print culture in Europe in the 15th century. Prior to this period, most literary and artistic works were created anonymously or attributed to collective or anonymous sources, such as folklore or religious traditions. However, with the rise of printing, texts became more easily reproducible and marketable, and there emerged a need for individual authors to take credit for their works. The notion of authorship was closely tied to the idea of originality and ownership, as authors sought to assert their exclusive rights to their works and to distinguish themselves from other writers. This was supported by the development of copyright law, which granted legal protection to authors and their works, and helped to establish a market for literary and artistic works. The idea of the author as a singular, autonomous figure gained further prominence in the 18th and 19th centuries, with the emergence of romanticism and the cult of the individual. This period saw the rise of the idea of the artist as a genius, whose works were the product of their own unique creativity and imagination. This idea was further reinforced by the rise of literary criticism, which focused on the interpretation and analysis of individual works and their authors. However, as Michel Foucault and other scholars have argued, the notion of authorship is not a universal or timeless concept, but rather a historically contingent and culturally specific one. Different societies ad cultures have different understandings of authorship, and these have shifted over time in response to changes in technology, culture, and social values. As it stands now, authorship in its traditional form can hardly be applied in a context where automated collaborations provide more than 50% of the generated material. This is true for multiple art fields. Visual Arts (Mario Klingemann, Sofia Crespo, Memo Atken, Ooouch, etc.), Music (Dadabots, YACHT, Holly Herndon), Literature, etc. Very soon this will also be true for Architecture. The consequence is also an entire rethinking of the concept of the sole genius. This notion, developed by German Romanticists in the early 19th century, is, in the current context of AI-assisted creativity, completely obsolete, as we are drawing from the genius of hundreds of thousands of artists and artworks in order to interrogate the latent space for unseen artistic opportunities. More akin to an archeological dig leading to the discovery of a next-generation jet fighter plane.
Efficiently evaluating loop integrals in the EFTofLSS using QFT integrals with massive propagators

Published: January 2024

Abstract
We develop a new way to analytically calculate loop integrals in the Effective Field Theory of Large Scale-Structure. Previous available methods show severe limitations beyond the one-loop power spectrum due to analytical challenges and computational and memory costs. Our new method is based on fitting the linear power spectrum with cosmology-independent functions that resemble integer powers of quantum field theory massive propagators with complex masses. A remarkably small number of them is sufficient to reach enough accuracy. Similarly to former approaches, the cosmology dependence is encoded in the coordinate vector of the expansion of the linear power spectrum in our basis. We first produce cosmology-independent tensors where each entry is the loop integral evaluated on a given combination of basis vectors. For each cosmology, the evaluation of a loop integral amounts to contracting this tensor with the coordinate vector of the linear power spectrum. The 3-dimensional loop integrals for our basis functions can be evaluated using techniques familiar to particle physics, such as recursion relations and Feynman parametrization. We apply our formalism to evaluate the one-loop bispectrum of galaxies in redshift space. The final analytical expressions are quite simple and can be evaluated with little computational and memory cost. We show that the same expressions resolve the integration of all one-loop N-point function in the EFTofLSS. This method, which is originally presented here, has already been applied in the first one-loop bispectrum analysis of the BOSS data to constraint ΛCDM parameters and primordial non-Gaussianities [1, 2].
Depth and Spatial Variation of the Shear Wave Attenuation Parameters in the Shallow Crust and Lower Crust/Upper Mantle of Mt. Etna (Italy)

Published: January 2024

AbstractSeismic wave attenuation is a key feature of seismic wave propagation that provides constraints on the composition and physical state of the medium within the Earth. We separated intrinsic and scattering attenuation coefficients for the shallow crust and lower crust/upper mantle in the Mt. Etna area. For this purpose, the Multiple Lapse Time Window Analysis (MLTWA) was applied to two groups of earthquakes, well separated in depth. We also studied the spatial variation of the attenuation parameters by dividing the study area into four sectors around Etna. The results show an effective homogeneity of the propagation characteristics inside Etna and, in particular, some lateral variations and minor variations with depth. We observe that structural discontinuities and lithology control scattering losses at all frequencies, with higher scattering in the shallow crust. The intrinsic absorption shows no sensitivity to the presence of these main geological structures and is quite uniform for different depths. Furthermore, compared to the northern sector of the volcano, the southern one shows stronger scattering attenuation at low frequencies. This pattern correlates well with the high seismic activity along most of Etna’s active tectonic structures and ascending magmatic fluids that characterize this sector of the volcano. Although we only discuss the differences in the "average" scattering and inelastic properties of the investigated volumes, the results of this study are very informative about the characteristics of each region. Moreover, they suggest that a future study is necessary, providing a more detailed picture of the spatial distribution of seismic attenuation in the study area, through a 3D inversion of the attenuation parameters estimated along the single source-receiver paths.

Abstract
Due to increasing demand for high and stable crop production, human populations are highly dependent on pesticide use for growing and storing food. Environmental monitoring of these agrochemicals is therefore of utmost importance, because of their collateral effects on ecosystem and human health. Even though most current-use analytical methods achieve low detection limits, they require procedures that are too complex and costly for routine monitoring. As such, there has been an increased interest in biosensors as alternative or complementary tools to streamline detection and quantification of environmental contaminants. In this work, we developed a biosensor for environmental monitoring of tebuconazole (TEB), a common agrochemical fungicide. For that purpose, we engineered S. cerevisiae cells with a reporter gene downstream of specific promoters that are expressed after exposure to TEB and characterized the sensitivity and specificity of this model system. After optimization, we found that this easy-to-use biosensor consistently detects TEB at concentrations above 5 μg L−1 and does not respond to realistic environmental concentrations of other tested azoles, suggesting it is specific. We propose the use of this system as a complementary tool in environmental monitoring programs, namely, in high throughput scenarios requiring screening of numerous samples.

Key points
• A yeast-based biosensor was developed for environmental monitoring of tebuconazole.
•The biosensor offers a rapid and easy method for tebuconazole detection ≥ 5 μg L−1.
•The biosensor is specific to tebuconazole at environmentally relevant concentrations.
Glycoprotein 2 as a gut gate keeper for mucosal equilibrium between inflammation and immunity
Authors: Zhang Zhongwei , Tanaka Izumi , Nakahashi-Ouchida Rika , Ernst Peter B. , Kiyono Hiroshi , Kurashima Yosuke 
Published: January 2024

AbstractGlycoprotein 2 (GP2) is a widely distributed protein in the digestive tract, contributing to mucosal barrier maintenance, immune homeostasis, and antigen-specific immune response, while also being linked to inflammatory bowel disease (IBD) pathogenesis. This review sheds light on the extensive distribution of GP2 within the gastrointestinal tract and its intricate interplay with the immune system. Furthermore, the significance of GP2 autoantibodies in diagnosing and categorizing IBD is underscored, alongside the promising therapeutic avenues for modulating GP2 to regulate immunity and maintain mucosal balance.

Published: January 2024

Abstract
Objectives
To compare functional outcomes and complication rates of anterolateral advancement pharyngoplasty (ALA) versus barbed reposition pharyngoplasty (BRP) in the treatment of obstructive sleep apnea patients with palatal and lateral pharyngeal wall collapse.

Study design
Prospective study.

Setting
University hospitals.

Subjects and methods
Forty-six patients were included in this study. Patients were divided into two groups randomly, group 1 (23 cases) underwent anterolateral advancement pharyngoplasty and group 2 (23 cases) underwent barbed relocation pharyngoplasty. According to the following criteria: both sex, age between 18 and 65 years, body mass index ≤ 32 kg/m2, Friedman stage II or III, type I Fujita, nocturnal polysomnography study diagnostic for OSA, retropalatal and lateral pharyngeal wall collapse, diagnosis with flexible nasoendoscopy during a Muller’s maneuver based on a 5-point scale and drug-induced sleep endoscopy. Patients who suffered from retroglossal airway collapse were rolled out.

Results
Apnea–hypopnea index decreased from 27.50 ± 11.56 to 11.22 ± 7.63 (P ≤ .001) in group 1 and from 33.18 ± 10.94 to 12.38 ± 6.77 (P ≤ .001) in group 2. Retropalatal posterior airway space increased from 9.84 ± 1.29 mm to 21.48 ± 2.8 mm (P ≤ .001) in group 1 and increased from 10.26 ± 1.2 mm to 22.86 ± 2.62 mm (P ≤ .001) in group 2. Retropalatal space volume increased from 1.9 ± 0.68 cm3 to 2.75 ± 0.7 cm3 (P ≤ .001) in group 1 and increased from 1.96 ± 0.88 cm3 to 2.82 ± 0.83 cm3 (P ≤ .001) in group 2. Surgical success was 86.95% in group 1 compared to 82.6% in group 2.

Conclusions
Both techniques appear to be effective with a high surgical success rate in the treatment of OSA patients with retropalatal and lateral pharyngeal wall collapse.

AbstractPost-acute sequelae of COVID-19 can present as multi-organ pathology, with neuropsychiatric symptoms being the most common symptom complex, characterizing long COVID as a syndrome with a significant disease burden for affected individuals. Several typical symptoms of long COVID, such as fatigue, depressive symptoms and cognitive impairment, are also key features of other psychiatric disorders such as myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and major depressive disorder (MDD). However, clinically successful treatment strategies are still lacking and are often inspired by treatment options for diseases with similar clinical presentations, such as ME/CFS. Acetylcarnitine, the shortest metabolite of a class of fatty acid metabolites called acylcarnitines and one of the most abundant blood metabolites in humans can be used as a dietary/nutritional supplement with proven clinical efficacy in the treatment of MDD, ME/CFS and other neuropsychiatric disorders. Basic research in recent decades has established acylcarnitines in general, and acetylcarnitine in particular, as important regulators and indicators of mitochondrial function and other physiological processes such as neuroinflammation and energy production pathways. In this review, we will compare the clinical basis of neuropsychiatric long COVID with other fatigue-associated diseases. We will also review common molecular disease mechanisms associated with altered acetylcarnitine metabolism and the potential of acetylcarnitine to interfere with these as a therapeutic agent. Finally, we will review the current evidence for acetylcarnitine as a supplement in the treatment of fatigue-associated diseases and propose future research strategies to investigate the potential of acetylcarnitine as a treatment option for long COVID.
Twisted Ways to Find Plane Structures in Simple Drawings of Complete Graphs
Authors: Aichholzer Oswin , García Alfredo , Tejel Javier , Vogtenhuber Birgit , Weinberger Alexandra 
Published: January 2024

AbstractSimple drawings are drawings of graphs in which the edges are Jordan arcs and each pair of edges share at most one point (a proper crossing or a common endpoint). A simple drawing is c-monotone if there is a point O such that each ray emanating from O crosses each edge of the drawing at most once. We introduce a special kind of c-monotone drawings that we call generalized twisted drawings. A c-monotone drawing is generalized twisted if there is a ray emanating from O that crosses all the edges of the drawing. Via this class of drawings, we show that every simple drawing of the complete graph with n vertices contains $$\Omega (n^{\frac{1}{2}})$$

Ω

pairwise disjoint edges and a plane cycle (and hence path) of length $$\Omega (\frac{\log n }{\log \log n})$$

Ω

. Both results improve over best previously published lower bounds. On the way we show several structural results and properties of generalized twisted and c-monotone drawings, some of which we believe to be of independent interest. For example, we show that a drawing D is c-monotone if there exists a point O such that no edge of D is crossed more than once by any ray that emanates from O and passes through a vertex of D.
