AbstractCarbon dots (CDs) find widespread attention due to their remarkable fluorescent and electronic properties. However, aggregation‐caused quenching currently limits the application of CDs in colored displays. The construction of CDs with color‐tunable solid‐state fluorescence (SSF) is rarely reported, since the preparation of SSF CDs is technically challenging. Herein, through surface ligand modulation, SSF CDs with an emission‐color span of almost 300 nm (from blue to deep red) were obtained. In‐depth structure‐property studies reveal that intra‐ and inter‐molecular hydrogen‐bonding inside SSF CDs provokes the emission properties in the aggregated state. Photodynamic characterizations demonstrate emission wavelengths can be switched smoothly by deliberately altering conjugation ability between substituent ligands and CDs core. Three‐dimensional printing patterning is used to create a range of emissive objects, demonstrating the commercial potential for use in optical lamps.
Site‐Selective Acylation of Pyranosides with Immobilized Oligopeptide Catalysts in Flow
Authors: Seitz Alexander , Wende Raffael C. , Schreiner Peter R. 
Published: December 2022

AbstractWe report the site‐selective acetylation of partially protected monosaccharides using immobilized oligopeptide catalysts, which are readily accessible via solid‐phase peptide synthesis. The catalysts are able to invert the intrinsic selectivity, which was determined using N‐methylimidazole, for a variety of pyranosides. We demonstrate that the catalysts are stable for multiple reaction cycles and can be easily reused after separation from the reaction solution. The catalysts can also be used in flow without loss of reactivity and selectivity.
Near Infrared Light‐to‐Heat Conversion for Liquid‐Phase Oxidation Reactions by Antimony‐Doped Tin Oxide Nanocrystals
Authors: Tada Hiroaki , Naya Shin‐ichi , Sugime Hisashi 
Published: December 2022

AbstractEffective utilization of the sunlight for chemical reactions is pivotal for dealing with the growing energy and environmental issues. So far, much effort has been focused on the development of semiconductor photocatalysts responsive to UV and visible light. However, the near infrared and infrared (NIR‐IR) light occupying ∼50 % of the solar energy has usually been wasted because of the low photon energy insufficient for the band gap excitation. Antimony doping into SnO2 (ATO) induces strong absorption due to the conduction band electrons in the NIR region. The absorbed light energy is eventually converted to heat via the interaction between hot electrons and phonons. This Concept highlights the photothermal effect of ATO nanocrystals (NCs) on liquid‐phase oxidation reactions through the NIR light‐to‐heat conversion. Under NIR illumination even at an intensity of ∼0.5 sun, the reaction field temperature on the catalyst surface is raised 20–30 K above the bulk solution temperature, while the latter is maintained near the ambient temperature. In some reactions, this photothermal local heating engenders the enhancement of not only the catalytic activity and selectivity but also the regeneration of catalytically active sites. Further, the photocatalytic activity of semiconductors can be promoted. Finally, the conclusions and possible subjects in the future are summarized.
Accurate Geometry and Non‐Covalent Interactions in 1‐Phenylethanol and its Monohydrate: A Rotational Study

Published: December 2022

AbstractThe pure rotational spectra of 1‐phenylethanol and its monohydrate were measured by using a pulsed jet Fourier transform microwave spectrometer. One conformer of the 1‐phenylethanol monomer with the trans form was observed in the pulsed jet. The experimental values of rotational constants of ten isotopologues, including eight mono‐substituted 13C and one D isotopologues, allow an accurate structure determination of the skeleton of 1‐phenylethanol. For its monohydrate, only one isomer has been observed, of which 1‐phenylethanol adopts the trans form and binds with water through an O−H⋅⋅⋅Ow and an Ow−H⋅⋅⋅π hydrogen bond. Each rotational transition displays a doublet with a relative intensity ratio of 1 : 3, due to a hindered internal rotation of water around its C2 axis. This study provides the information on accurate geometry of 1‐phenylethanol (PE) and large amplitude motion of water in the PE monohydrate.

AbstractBackgroundAlthough chemotherapy, the most widely used systemic treatment in triple‐negative breast cancer (TNBC), markedly improved the patients’ outcome, chemoresistance always occurs. This study purposed to explore new therapeutic strategies for the treatment of chemoresistance.Methods and resultsThe expression and prognostic value of DAB2IP were investigated in TNBC tissues and cell lines. Low DAB2IP expression predicted high mortality risk in TNBC. Inhibition of DAB2IP expression conferred cancer stem cell capacity and chemoresistance in TNBC cell lines. Using murine breast cancer (BC) xenograft models, we evaluated the association with DAB2IP and chemoresistance. DAB2IP inhibited TNBC tumourigenesis and chemoresistance in vivo. Further, we revealed that DAB2IP inhibited β‐catenin nuclear transport through competitive interaction with RAC1 and decreased β‐catenin accumulation in the cell nucleus. Finally, we found that the DNA methylation level was negatively associated with DAB2IP expression in TNBC. Inhibition of DNA methylation restored the DAB2IP expression and attenuated chemoresistance in TNBC.ConclusionsWe revealed that DAB2IP attenuates chemoresistance of TNBC via inhibition of RAC1‐mediated β‐catenin nuclear accumulation. Decitabine treatment results in re‐expression of DAB2IP by inhibiting DNA methylation and could be a potential therapeutic strategy for chemoresistance in TNBC.
Design of single and two phase modeled nanofluid CPU cooler and their numerical analysis
Authors: Yapıcı Özdiler Ezgi , Yurddaş Ali 
Published: December 2022

AbstractThe heating problems in electronic devices have become even more significant with the development of technology and the rapid increase in areas of use. In cases where passive cooling and active cooling processes are not sufficient to improve overheating in electronic devices, high temperature generation is prevented by liquid cooling if convenient. The effect of nanofluid use on heat transfer to improve the thermal performance of liquid cooling systems was examined with computational fluid dynamics from numerical methods in this research. For different cooler designs, both single‐phase and multiphase modeling methods were utilized in fluid modeling in the research involving forced convection and heat transfer in laminar and turbulent flow. The mathematical models utilized were validated on different experimental and numerical researches. The single‐phase modeling was conducted for pure H2O, 1% Al2O3, 5% Al2O3 nanofluids at different Reynolds numbers. The analyzes were conducted at different Reynolds values and the increase in Reynolds value decreases the maximum temperature value at the output. In the multiphase modeling method, the nanofluid Al2O3 is defined and modelled as a separate phase suspended in different sizes into the base fluid H2O. The use of nanofluid increased the thermal conductivity in both methods compared to the use of pure H2O. At the same time, the use of nanofluids at 5% concentration gave better results than 1% concentration. As the temperature distributions are examined, the Mixture model, one of the single‐phase and multiphase modeling methods, presents very similar distributions. The effect of nanofluids on thermal performance varies depending on many parameters. A significant one is the size of the suspended nanoparticle. Different particle sizes, 20, 30, and 40 nm, were investigated in both Mixture and Eulerian modeling approaches in this research. Two different design coolers were utilized in the researches. In these designs, the flow is distributed in parallel and serpentine. The flow distribution and pressure drop also had an effect on thermal performance. The temperatures were read lower in the serpentine block, which provides a more regular flow distribution.

AbstractBACKGROUNDThis study evaluates the treatment of vegetable oil industry wastewater using dual‐chamber microbial fuel cells (MFCs) via modification and surface area expansion of cost‐effective electrodes. The modified electrodes were applied as both the anode and cathode to investigate their treatment capacity and electrochemical performance. Carbon paper anodes were modified using TiO2‐HX@MWCNT‐COOH‐Al2O3 composite. Activated carbon powders originating from Bambuseae were used as the low‐cost catalyst for the carbon felt cathode. The synthesized catalysts were characterized by Field‐Emission Scanning Electron Microscope (FE‐SEM), Energy Dispersive X‐ray Spectroscopy (EDX), and Brunauer–Emmett–Teller (BET) techniques. The electrochemical properties of the MFCs were investigated by Electrochemical Impedance Spectroscopy (EIS).RESULTSThe highest average removal efficiencies of COD (chemical oxygen demand), BOD5 (5‐day biochemical oxygen demand), NH4+ (ammonium), NH3− (nitrate), TSS (total suspended solids), and VSS (volatile suspended solids) were 94 ± 3% (33 kgCODrem/m3.d), 89 ± 1% (12 kgBODrem/m3.d), 87 ± 1% (0.24 kgNH4+‐Nrem/m3.d), 74 ± 3% (0.05 kgNO3−‐N/m3.d), 79 ± 2% (1 kgCODrem/m3.d), and 65 ± 3% (0.73 kgCODrem/m3.d), respectively. The highest average power density of 30 ± 5 W/m3 was obtained when treating vegetable oil industry wastewater. The highest average coulombic efficiency (CE) of 85 ± 3% and energy efficiency (EE) of 35 ± 2% were achieved. The EIS results showed that the high conductivity and large unique surface area significantly enhanced the charge transfer efficiency on the electrode surface.CONCLUSIONThe results indicated that the TiO2‐HX@MWCNT‐COOH‐Al2O3 composite can be used to reinforce the performance of MFCs. © 2022 Society of Chemical Industry (SCI).
‘The Machine Takes Our Jobs Away’: The problem of technological unemployment in the work of Chicago sociologist William F. Ogburn
Authors: Kim Emy , Solovey Mark 
Published: December 2022

AbstractThis paper examines the Chicago sociologist William F. Ogburn's (1886–1959) views about technological unemployment, which were intimately connected to his analysis of the social impacts of technological developments and resulting social problems due to cultural lag. We trace the development of his views as seen through his well‐known 1922 book, Social Change with Respect to Culture and Original Nature, his important contributions to the President's Research Committee on Social Trends (1933), and his lesser‐known pamphlets designed for a broader audience—Living with Machines (1933), You and Machines (1934), and Machines and Tomorrow's World (1938). He used these pamphlets to educate the public about the dangers of new machines and technological unemployment. In doing so, he drew upon sociological analysis in his professional scholarly writings and his long‐standing personal interests in social betterment and social reform. Our analysis also calls into question the adequacy of existing scholarship on Ogburn that has emphasized his commitment to a statistical, dispassionate, and “objectivist” approach to social science research. We call for a revised, richer, and more complex view of Ogburn's work and legacy as one of the nation's leading social scientists during the first half of the 20th century.
Morphological and histochemical characterization of the pectoral fin muscle of batoids
Authors: Gabler‐Smith Molly K. , Coughlin David J. , Fish Frank E. 
Published: December 2022

AbstractBatoids differ from other elasmobranch fishes in that they possess dorsoventrally flattened bodies with enlarged muscled pectoral fins. Most batoids also swim using either of two modes of locomotion: undulation or oscillation of the pectoral fins. In other elasmobranchs (e.g., sharks), the main locomotory muscle is located in the axial myotome; in contrast, the main locomotory muscle in batoids is found in the enlarged pectoral fins. The pectoral fin muscles of sharks have a simple structure, confined to the base of the fin; however, little to no data are available on the more complex musculature within the pectoral fins of batoids. Understanding the types of fibers and their arrangement within the pectoral fins may elucidate how batoid fishes are able to utilize such unique swimming modes. In the present study, histochemical methods including succinate dehydrogenase (SDH) and immunofluoresence were used to determine the different fiber types comprising these muscles in three batoid species: Atlantic stingray (Dasyatis sabina), ocellate river stingray (Potamotrygon motoro) and cownose ray (Rhinoptera bonasus). All three species had muscles comprised of two muscle fiber types (slow‐red and fast‐white). The undulatory species, D. sabina and P. motoro, had a larger proportion of fast‐white muscle fibers compared to the oscillatory species, R. bonasus. The muscle fiber sizes were similar between each species, though generally smaller compared to the axial musculature in other elasmobranch fishes. These results suggest that batoid locomotion can be distinguished using muscle fiber type proportions. Undulatory species are more benthic with fast‐white fibers allowing them to contract their muscles quickly, as a possible means of escape from potential predators. Oscillatory species are pelagic and are known to migrate long distances with muscles using slow‐red fibers to aid in sustained swimming.
Implementing voluntary assisted dying laws in healthcare: Exploring beliefs to identify implementation hurdles
Authors: Hewitt Jayne , Lawson Charles , Verrall Brodie , Grealish Laurie 
Published: December 2022

AbstractThe number of countries introducing voluntary assisted dying (VAD) laws is increasing. Actively taking steps to end a person's life is contentious so implementing these laws into healthcare services presents unique challenges. Theoretically underpinned by the Advocacy Coalition Framework, this study identified the beliefs of classes of stakeholders who engaged with the parliamentary process associated with the introduction of VAD laws in Queensland, Australia. Submissions about VAD made to a parliamentary inquiry were allocated to a class and qualitatively analysed to identify underlying beliefs. The data were then subjected to statistical analysis including nonmetric dimensional scaling and one‐way analysis of similarity. Data visualisation techniques were used to generate a chord map and heatmap, to identify the belief types, as well as similarities and differences between beliefs and among classes. Fourteen different beliefs were identified in the 91 reviewed submissions. Six were deep core beliefs and eight were policy core beliefs. Beliefs could be associated with a positive or negative sentiment toward VAD. In this study, the class of Health Services expressed more negative sentiments to VAD than neutral or positive sentiments. The sentiments expressed by the class of Health Professionals were equally divided between positive, neutral and negative. These findings provide important insights for implementors as laws become operational. In particular, for organisations that provide health services, clear articulation of their stance in relevant policy and guidance documents is recommended.

Published: December 2022

Analysis of structural and functional connectivity (FC) of human brains is of pivotal importance for diagnosis of cognitive ability. The Human Connectome Project (HCP) provides an excellent source of neural data across different regions of interest (ROIs) of the living human brain. Individual specific data were available in the form of time varying covariance matrices representing the brain activity as the subjects perform a specific task. As a preliminary objective of studying the heterogeneity of brain connectomics across the population, we develop a probabilistic model for a sample of covariance matrices using a scaled Wishart distribution. We stress here that our data units are available in the form of covariance matrices, and we use the Wishart distribution to create our likelihood function rather than its more common usage as a prior on covariance matrices. Based on empirical explorations suggesting the data matrices to have a low effective rank, we further model the center of the Wishart distribution using an orthogonal factor model type decomposition. We encourage shrinkage toward a low rank structure through a novel shrinkage prior and discuss strategies to sample from the posterior distribution using a combination of Gibbs and slice sampling. The efficacy of the approach is explored in various simulation settings and exemplified on several case studies including our motivating HCP data. We extend our modeling framework to a dynamic setting to detect change points.
Coupling Transition Metal Compound with Single‐Atom Site for Water Splitting Electrocatalysis

Published: December 2022

AbstractSingle‐atom site catalysts (SACs) provide an ideal platform to identify the active centers, explore the catalytic mechanism, and establish the structure‐property relationships, and thus have attracted increasing interests for electrocatalytic energy conversion. Substantial endeavors have been devoted to the construction of carbon‐supported SACs, and their progress have been comprehensively reviewed. Compared with carbon‐supported SACs, transition metal compounds (TMCs)‐supported SACs are still in their infancy in the field of electrocatalysis. However, they have also aroused ever‐increasing attention for driving electrocatalytic water splitting, and emerged as an indispensable class of SACs in recent years, predominately owing to their inherently structural features, such as rich anchoring sites, surface defects, and lattice vacancy. Herein, in this review, we have systematically summarized the recent advances of a variety of TMC supported SACs toward electrocatalytic water splitting. The advanced characterization techniques and theoretical analyses for identifying and monitoring the atomic structure of SACs are firstly manifested. Subsequently, the anchoring and stabilization mechanisms for TMC supported SACs are also highlighted. Thereafter, the advances of TMC supported SACs for driving water electrolysis are systematically unraveled.
The Unity of Robustness: Why Agreement Across Model Reports is Just as Valuable as Agreement Among Experiments
Authors: Dethier Corey 
Published: December 2022

AbstractA number of philosophers of science have argued that there are important differences between robustness in modeling and experimental contexts, and—in particular—many of them have claimed that the former is non-confirmatory. In this paper, I argue for the opposite conclusion: robust hypotheses are confirmed under conditions that do not depend on the differences between and models and experiments—that is, the degree to which the robust hypothesis is confirmed depends on precisely the same factors in both situations. The positive argument turns on the fact that confirmation theory doesn’t recognize a difference between different sources of evidence. Most of the paper is devoted to rebutting various objections designed to show that it should. I end by explaining why philosophers of science have (often) gone wrong on this point.
Canonical tessellations of decorated hyperbolic surfaces
Authors: Lutz Carl O. R. 
Published: December 2022

AbstractA decoration of a hyperbolic surface of finite type is a choice of circle, horocycle or hypercycle about each cone-point, cusp or flare of the surface, respectively. In this article we show that a decoration induces a unique canonical tessellation and dual decomposition of the underlying surface. They are analogues of the weighted Delaunay tessellation and Voronoi decomposition in the Euclidean plane. We develop a characterisation in terms of the hyperbolic geometric equivalents of Delaunay’s empty-discs and Laguerre’s tangent-distance, also known as power-distance. Furthermore, the relation between the tessellations and convex hulls in Minkowski space is presented, generalising the Epstein–Penner convex hull construction. This relation allows us to extend Weeks’ flip algorithm to the case of decorated finite type hyperbolic surfaces. Finally, we give a simple description of the configuration space of decorations and show that any fixed hyperbolic surface only admits a finite number of combinatorially different canonical tessellations.
On the weakness of short-range interactions in Fermi gases
Authors: Griesemer M. , Hofacker M. 
Published: December 2022

AbstractUltracold quantum gases of equal-spin fermions with short-range interactions are often considered free even in the presence of strongly binding spin-up–spin-down pairs. We describe a large class of many-particle Schrödinger operators with short-range pair interactions, where this approximation can be justified rigorously.
Resetting Prices: Estimating the Effect of Tuition Reset Policies on Institutional Finances and Enrollment
Authors: Ward James Dean , Corral Daniel 
Published: December 2022

AbstractPrivate nonprofit colleges are increasingly using tuition resets, or a decrease in sticker price by at least 5%, to attract new students and counter declining demand. While discounting tuition with institutional aid is a common practice to get accepted students to matriculate and to increase affordability, a tuition reset is a more transparent approach that moves colleges away from a high aid/high tuition model. The authors find minimal evidence that these policies increase student enrollment in the long run, but that there may be short-term impacts. As expected, institutional aid decreases and varies directly with the size of the sticker price reduction. The average net price students pay decreases, but this effect may be driven by changes in the estimated non-tuition elements of the total cost of attendance. Finally, net tuition revenue appears unrelated to tuition resets. These findings call into question the efficacy of this practice.
Ownership, ontology, and the contemporary dance commons
Authors: Blades Hetty 
Published: December 2022

AbstractThis article considers the “commons” in relationship to contemporary dance in the United Kingdom. I highlight the norms and expectations that shape the sharing of dance in this context by outlining four implicit rules that govern circulation and ownership. I go on to highlight how dance’s circulation outside of legal structures is in part due to its ontology through the examination of choreographer and visual artist Florence Peake’s work RITE (2018) and its relationship to choreographer Vaslav Nijinsky’s Le Sacre du printemps (The Rite of Spring) (1913).
