    Unveiling the Associative Mechanisms Underlying the Additive Bias: Using an Implicit Association Test to Gain Insight into People’s Preference for Additive Actions.
    (Wiley) Crilly, Nathaniel; Neroni, Maria Adriana; Brandimonte, Maria Antonella; Crilly, Nathan [0000-0003-0784-6802]
    When faced with the need to transform an object, idea, or situation, people have a tendency to favor adding new components rather than removing existing ones. This is called the additive bias. Previous research, along with historical and anecdotal examples, shows that this bias may significantly reduce problem-solving abilities and have a detrimental impact on the innovation process. In this study, our objective was to develop a novel tool, the additive bias implicit association test (ad-IAT), to investigate the reasons underlying people’s preference for additive actions. By using this tool, we empirically demonstrated that people displayed an inherent tendency to assign a positive valence to additive concepts and to perceive additive actions as safer and more functional than subtractive concepts. Importantly, we also found that implicit preference for addition resulted in participants favoring additive actions while neglecting subtractive alternatives when engaged in a problem-solving task. Collectively, our series of experiments substantiated the effectiveness of our ad-IAT in uncovering and quantifying the additive bias. This, in turn, provided a deeper comprehension of the underlying factors contributing to the bias and its impact on people’s behavior.

    The landscape and networks of southwest Samos: new evidence from surface-survey ceramics
    (Cambridge University Press) Loy, Michael; Huy, Sabine; Loy, Michael [0000-0001-9120-0515]
    This article uses the assemblage of surface-survey ceramics collected in the 2021 and 2022 WASAP field seasons to discuss the landscape structure and networking patterns (internal and external to the island) of Archaic through Byzantine southwest Samos. Collected in the basin of Marathokampos with intensive field pedestrian methods, a subset of a dataset of 2,106 ceramics is discussed alongside the environmental context of their findspots. Spatial analysis is used to identify 15 ‘Areas of Interest’ in the landscape, densely populated by surface ceramics, while detailed typological analysis of the ceramics helps to assign dates of activity across the region. The ceramic assemblage is compared to material from the Heraion Sanctuary of Samos, to local Ionian ceramics, and to ceramics from the broader Aegean and Mediterranean, to evaluate the network of contacts sustained by southwest Samos gradually expanded between the Archaic and Byzantine periods.

    Child health research is considered essential to paediatric training. However, due to service provision demands and workforce planning, research capacity within paediatric consultant contracts is declining[1]. This affects paediatric trainees who perceive lack of leadership in this domain. Considering these concerns, in 2021 the Royal College of Paediatrics and Child Health (RCPCH) established the Trainee Research Network (TRN) to support regional research. To broadly evaluate trainee participation in research as a marker of future UK research capacity, we conducted a national survey of trainees’ experiences to help identify the breadth of research involvement and to identify barriers and facilitators to participation.

    Tools for Measuring Photosynthesis at Different Scales.
    (Springer US) Walker, Berkley J; Driever, Steven M; Kromdijk, Johannes; Lawson, Tracy; Busch, Florian A; Sarah Covshoff; Kromdijk, Johannes [0000-0003-4423-4100]
    Measurements of in vivo photosynthesis are powerful tools that probe the largest fluxes of carbon and energy in an illuminated leaf, but often the specific techniques used are so varied and specialized that it is difficult for researchers outside the field to select and perform the most useful assays for their research questions. The goal of this chapter is to provide a broad overview of the current tools available for the study of photosynthesis, both in vivo and in vitro, so as to provide a foundation for selecting appropriate techniques, many of which are presented in detail in subsequent chapters. This chapter will also organize current methods into a comparative framework and provide examples of how they have been applied to research questions of broad agronomical, ecological, or biological importance. This chapter closes with an argument that the future of in vivo measurements of photosynthesis lies in the ability to use multiple methods simultaneously and discusses the benefits of this approach to currently open physiological questions. This chapter, combined with the relevant methods chapters, could serve as a laboratory course in methods in photosynthesis research or as part of a more comprehensive laboratory course in general plant physiology methods.

    The Role of Turbulence Transport in Mechanical Energy Budgets
    (ASME International, 2024-10-01) Przytarski, Pawel J; Lengani, Davide; Simoni, Daniele; Wheeler, Andrew PS
    Abstract In this article, we study the role of turbulence transport on loss prediction using high fidelity scale-resolving simulations. For this purpose, we use eight high-fidelity simulation datasets and compute flux of entropy and stagnation pressure transport equation budgets for all the cases. We find that under certain unsteady inflow conditions, the stagnation pressure coefficient is not a reliable loss metric even at low Mach number conditions. This is due to the turbulence transport terms. The impact of these terms, typically assumed to be negligible, made stagnation pressure loss coefficient underpredict loss from 0% to over 40% when compared to entropy loss coefficient for cases considered here. This effect was most pronounced for the cases with highly unsteady inflow conditions and at low Reynolds numbers.

    Polaronic Mass Enhancement and Polaronic Excitons in Metal Halide Perovskites
    Baranowski, Michal; Nowok, Andrzej; Galkowski, Krzysztof; Dyksik, Mateusz; Surrente, Alessandro; Maude, Duncan; Zacharias, Marios; Volonakis, George; Stranks, Samuel; Even, Jacky; Maczka, Miroslaw; Nicholas, Robin; Plochocka, Paulina; Stranks, Sam [0000-0002-8303-7292]
    In metal halide perovskites the complex dielectric screening together with low energy of phonon modes leads to non-negligible Fr¨ohlich coupling. While this feature of perovskites has been already used to explain some of the puzzling aspects of carrier transport in these materials, the possible impact of polaronic effects on the optical response, especially excitonic properties, is much less explored. Here with the use of magneto-optical spectroscopy, we revealed the non-hydrogenic character of the excitons in metal halide perovskites, resulting from the pronounced Fr¨ohlich coupling. Our results can be well described by the polaronic-exciton picture where electron and hole interaction are no longer described by a Coulomb potential. Furthermore, we show experimental evidence that the carrier-phonon interaction leads to the enhancement of the carrier’s effective mass. Notably, our measurements reveal a pronounced temperature dependence of the carrier’s effective mass, which we attribute to a band structure renormalization induced by the population of low-energy phonon modes. This interpretation finds support in our first-principles calculations.

    Ideas Behind the Tryptophan-Mediated Petasis Reaction (TMPR) Concept for Peptide Stapling.
    (Wiley) Krajcovicova, Sona
    This Concept short review offers an insightful analysis of pivotal research papers and explores the key synthetic ideas behind the intersection of two realms in peptide chemistry: using tryptophan and Petasis multicomponent reactions for macrocyclisation and labelling of peptides. The recently published tryptophan-mediated Petasis reaction (TMPR) concept represents a critical junction between these two worlds, highlighting how combining such methodologies leads to more effective and versatile synthetic strategies, setting a potentially new direction for future research in the field of peptide-drug conjugates.

    Hate-Speech Bans are at Odds with Central Principles of Liberalism
    (Springer) Kramer, Matthew
    In line with my 2021 book Freedom of Expression as Self-Restraint – albeit in a much shorter compass – this essay will argue against the moral defensibility of hate-speech laws like those in the United Kingdom and Canada and the Antipodes and most countries of western Europe. Such laws contravene the moral principle of freedom of expression, and therefore contravene one of the central principles of liberal democracy. After expounding the principle of freedom of expression, this essay explains why some hateful utterances can be prohibited in full compliance with that principle and without any hate-speech legislation. It then recounts how a system of governance should deal with hateful utterances that cannot properly be prohibited. Finally, the essay argues that hate-speech laws are profoundly degrading for any society in which they are adopted.

    Actually Existing Smart Forests: A Proposal for Pluralizing Eco-Technical Worlds
    (Sage) Gabrys, Jennifer; Westerlaken, Michelle; Fatimah, Yuti Ariani; Gabrys, Jennifer [0000-0001-5545-2459]
    The “actually existing smart city” is a familiar figure and concept within smart environments research. Usually, “actually existing” analyses challenge the often-hyperbolic proposals for smart cities by grounding research in built urban conditions. Cities are not exemplars of digital interconnectivity and seamless functioning, many smart cities researchers note. Instead, they are complicated sites of uneven urban development. Such research places speculative urban visions in contrast with empirical conditions to reflect upon and re-evaluate smart city proposals as they hit the ground. Building on this critical research, this article considers how smart environments are proliferating beyond cities to other milieus, including forests. By first reviewing “actually existing” smart cities literature along with “actually existing” references in social and political theory, we consider how to update and advance the “actually existing” analytic by revisiting the perceived rift between speculative and actual environments. Drawing on interviews with smart forest stakeholders, the second part of the article develops three examples of “actually existing” smart forests that demonstrate how inseparable the envisioning, making, and sustaining of smart environments can be. Even more than empirical conditions counteracting fantastical visions, we propose the “actually existing” analytic can be updated and mobilized to examine how plurality, contestation, and democratic participation are at stake not just in the lived conditions of smart environments but also in the abstract and provisional contours of computational technologies as they shape and transform milieus. We suggest that engagement with the plurality of speculations, material conditions, and practices is crucial for ensuring “actually existing” eco-technical worlds and relations are attuned to equity and environmental flourishing.

    3D Printed PEDOT:PSS-based Conducting and Patternable Eutectogel Electrodes for Machine Learning on Textiles
    (Elsevier) Malliaras, Georgios; Malliaras, George [0000-0002-4582-8501]
    The proliferation of medical wearables necessitates the development of novel electrodes for cutaneous electrophysiology. In this work, poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is combined with a deep eutectic solvent (DES) and polyethylene glycol acrylate (PEGDA) to develop printable and biocompatible electrodes for long-term cutaneous electrophysiology recordings. The impact of printing parameters on the conducting properties, morphological characteristics, mechanical stability and biocompatibility of the material were investigated. The optimised eutectogel formulations were fabricated in four different patterns —flat, pyramidal, striped and wavy— to explore the influence of electrode geometry on skin conformability and mechanical contact. These electrodes were employed for impedance and forearm EMG measurements. Furthermore, arrays of twenty electrodes were embedded into a textile and used to generate body surface potential maps (BSPMs) of the forearm, where different finger movements were recorded and analysed. Finally, BSPMs for three different letters (B, I, O) in sign-language were recorded and used to train a logistic regressor classifier able to reliably identify each letter. This novel cutaneous electrode fabrication approach offers new opportunities for long-term electrophysiological recordings, online sign-language translation and brain-machine interfaces.

    Single molecule characterisation of salivary protein aggregates from Parkinson's disease patients – a pilot study
    (Oxford University Press) Klenerman, David; Klenerman, David [0000-0001-7116-6954]
    Saliva is a convenient and accessible biofluid that has potential as a future diagnostic tool for Parkinson’s disease (PD). Candidate diagnostic tests for PD to date have predominantly focused on measurements of alpha-synuclein in cerebrospinal fluid (CSF), but there is a need for accurate tests utilising more easily accessible sample types. Prior studies utilising saliva have used bulk measurements of salivary α-synuclein to provide diagnostic insight. Aggregate structure may influence the contribution of α-synuclein to disease pathology. Single molecule approaches can characterise the structure of individual aggregates present in the biofluid and may therefore provide greater insight than bulk measurements. We have employed an antibody-based single-molecule pulldown (SiMPull) assay to quantify salivary α-synuclein and amyloid-β peptide (Aβ) aggregate number and subsequently super-resolved captured aggregates using direct Stochastic Optical Reconstruction Microscopy (dSTORM) to describe their morphological features. We show that the salivary α-synuclein aggregate/Aβ aggregate ratio is increased almost two-fold in PD patients (n = 20) compared to controls (n = 20, p <0.05). Morphological information also provides insight with PD saliva containing a greater proportion of larger and more fibrillar Aβ aggregates than control saliva (p <0.05). Furthermore, the combination of count and morphology data provides greater diagnostic value than either measure alone distinguishing between the people with PD (n = 17) and controls (n = 18) with a high degree of accuracy (AUC = 0.87, p <0.001) and a larger dynamic range. We therefore demonstrate for the first time the application of highly sensitive single molecule imaging techniques to saliva. In addition, we show that aggregates present within saliva retain relevant structural information further expanding the potential utility of saliva-based diagnostic methods.

    Digital Twins for Knowledge Management During Earthquake Emergency
    (2024-06-08) Ozturk, Gozde Basak; Brilakis, Ioannis; Ozen, Busra; Celenk, Ozlem; Soygazi, Fatih; Brilakis, Ioannis [0000-0003-1829-2083]
    The chaotic emergency environment can create obstacles that may complicate prompt and effective responses for a resilient emergency management. The provision of vital information related to health services, shelter, nutrition, and availability of infrastructure is of utmost importance. In the context of earthquake emergency, Knowledge Management (KM) encompasses various techniques and approaches for acquiring, storing, generating, assessing, and sharing knowledge for efficient and effective mobility of people, goods, and services. Digital Twins (DT) can serve as a platform for KM, addressing challenges in earthquake emergency action plans and facilitating information sharing during critical hours and in the aftermath of disasters, ensuring timely and informed decisions for the survival of victims. This paper presents an Earthquake Emergency Knowledge Management framework through DT, based on expert judgment, and the scientometric analysis and mapping to identify gaps in existing KM methods. The proposed conceptual framework aims to improve response time and facilitate KM during an earthquake emergency to meet the primary needs of victims for survival. However, it's important to recognize potential limitations, such as challenges in resource-constrained settings or areas lacking digital infrastructure. Future studies may further focus on the secondary emergency requirements for the days following the earthquake, addressing not only survival but also recovery needs.

    Linear stability prediction of vortex structures on high pressure turbine blades
    (MDPI AG, 2017-05-26) Zauner, M; Sandham, ND; Wheeler, APS; Sandberg, RD
    Velocity profiles are extracted from time- and span-averaged direct numerical simulation data, describing the flow over a high-pressure turbine vane linear cascade near engine-scale conditions with reduced inlet disturbance levels. Based on these velocity profiles, local as well as non-local linear stability analysis of the boundary-layer over the suction side of the vane is carried out in order to characterise a linearly unstable region close to the trailing edge. The largest growth rates are found for oblique modes, but those are only slightly more unstable than 2D modes, which describe the locations and frequencies of most unstable modes very well. The frequencies of the most unstable linear modes predict with good accuracy the predominant frequencies found in the direct numerical simulations (DNS) close to the trailing edge.

    (Institute of Electrical and Electronics Engineers (IEEE), 2024-05-15) Torres-Ferrera, P; Faruk, MS; Kovacs, IB; Savory, SJ; Torres-Ferrera, P [0000-0001-9374-4938]; Faruk, MS [0000-0002-6045-6291]; Kovacs, IB [0000-0002-6797-3507]; Savory, SJ [0000-0002-6803-718X]
    A simple single-polarization heterodyne optical network unit (ONU) receiver with Alamouti-coding based polarization diversity at the optical line terminal (OLT) side is a promising solution for passive optical networks (PON) beyond 50 Gbps. The special equalizer required for data recovery of such system has been demonstrated for 200 Gbps PON downstream using offline processing of serial data. In this letter, we extend such equalizer implementation with parallel processing that is required for real-time implementation. The proof-of-concept experiment for 200 Gbps downstream transmission is demonstrated to show the effectiveness of the proposed digital signal proccesing (DSP). The impact of phase noise and limitation of degree of parallelism are further investigated via numerical simulations.

    International consensus on mitotane treatment in pediatric patients with adrenal cortical tumors: indications, therapy, and management of adverse effects.
    (Oxford University Press (OUP), 2024-03-30) Riedmeier, Maria; Antonini, Sonir RR; Brandalise, Silvia; Costa, Tatiana El Jaick B; Daiggi, Camila M; de Figueiredo, Bonald C; de Krijger, Ronald R; De Sá Rodrigues, Karla Emília; Deal, Cheri; Del Rivero, Jaydira; Engstler, Gernot; Fassnacht, Martin; Fernandes Luiz Canali, Gabriela C; Molina, Carlos A Fernandes; Gonc, Elmas Nazli; Gültekin, Melis; Haak, Harm R; Guran, Tulay; Hendriks Allaird, Emile J; Idkowiak, Jan; Kuhlen, Michaela; Malkin, David; Meena, Jagdish Prasad; Pamporaki, Christina; Pinto, Emilia; Puglisi, Soraya; Ribeiro, Raul C; Thompson, Lester DR; Yalcin, Bilgehan; Van Noesel, Max; Wiegering, Verena; Riedmeier, Maria [0000-0002-3273-1794]; Del Rivero, Jaydira [0000-0001-9710-4030]; Fassnacht, Martin [0000-0001-6170-6398]; Guran, Tulay [0000-0003-2658-6866]; Kuhlen, Michaela [0000-0003-4577-0503]; Puglisi, Soraya [0000-0002-2883-6139]
    OBJECTIVE: Mitotane is an important cornerstone in the treatment of pediatric adrenal cortical tumors (pACC), but experience with the drug in the pediatric age group is still limited and current practice is not guided by robust evidence. Therefore, we have compiled international consensus statements from pACC experts on mitotane indications, therapy, and management of adverse effects. METHODS: A Delphi method with 3 rounds of questionnaires within the pACC expert consortium of the international network groups European Network for the Study of Adrenal Tumors pediatric working group (ENSAT-PACT) and International Consortium of pediatric adrenocortical tumors (ICPACT) was used to create 21 final consensus statements. RESULTS: We divided the statements into 4 groups: environment, indications, therapy, and adverse effects. We reached a clear consensus for mitotane treatment for advanced pACC with stages III and IV and with incomplete resection/tumor spillage. For stage II patients, mitotane is not generally indicated. The timing of initiating mitotane therapy depends on the clinical condition of the patient and the setting of the planned therapy. We recommend a starting dose of 50 mg/kg/d (1500 mg/m²/d) which can be increased up to 4000 mg/m2/d. Blood levels should range between 14 and 20 mg/L. Duration of mitotane treatment depends on the clinical risk profile and tolerability. Mitotane treatment causes adrenal insufficiency in virtually all patients requiring glucocorticoid replacement shortly after beginning. As the spectrum of adverse effects of mitotane is wide-ranging and can be life-threatening, frequent clinical and neurological examinations (every 2-4 weeks), along with evaluation and assessment of laboratory values, are required. CONCLUSIONS: The Delphi method enabled us to propose an expert consensus statement, which may guide clinicians, further adapted by local norms and the individual patient setting. In order to generate evidence, well-constructed studies should be the focus of future efforts.

    Environmental and genetic influence on the rate and spectrum of spontaneous mutations in Escherichia coli.
    (Microbiology Society, 2024-04) Gifford, Danna R; Bhattacharyya, Anish; Geim, Alexandra; Marshall, Eleanor; Krašovec, Rok; Knight, Christopher G
    Spontaneous mutations are the ultimate source of novel genetic variation on which evolution operates. Although mutation rate is often discussed as a single parameter in evolution, it comprises multiple distinct types of changes at the level of DNA. Moreover, the rates of these distinct changes can be independently influenced by genomic background and environmental conditions. Using fluctuation tests, we characterized the spectrum of spontaneous mutations in Escherichia coli grown in low and high glucose environments. These conditions are known to affect the rate of spontaneous mutation in wild-type MG1655, but not in a ΔluxS deletant strain - a gene with roles in both quorum sensing and the recycling of methylation products used in E. coli's DNA repair process. We find an increase in AT>GC transitions in the low glucose environment, suggesting that processes relating to the production or repair of this mutation could drive the response of overall mutation rate to glucose concentration. Interestingly, this increase in AT>GC transitions is maintained by the glucose non-responsive ΔluxS deletant. Instead, an elevated rate of GC>TA transversions, more common in a high glucose environment, leads to a net non-responsiveness of overall mutation rate for this strain. Our results show how relatively subtle changes, such as the concentration of a carbon substrate or loss of a regulatory gene, can substantially influence the amount and nature of genetic variation available to selection.

    Assessment of the Bearing Capacity of Double Shear-Bolted Connections in Structural Steel
    Kookalani, Soheila; Parn, Erika; Brilakis, Ioannis; Kookalani, Soheila [0000-0001-8731-4413]
    This research explored the accurate prediction of bearing capacity in double shear-bolted connections constructed from structural steel using the CatBoost machine learning (ML) algorithm. The study incorporates the Shapley additive explanations (SHAP) method to enhance interpretability, elucidating the significance of impact of each variable on predictions at both local and global scales. The results demonstrate that SHAP provides valuable insights into the decision-making process of the ML model. They identify pivotal variables for specific scenarios, enriching the comprehension of the predictions. Crucially, the alignment between feature importance derived from the ML model and SHAP underscores the criticality of certain factors in bearing capacity estimation. This study advances the precision of bearing capacity forecasts for double shear-bolted connections and underscores the advantages of employing interpretable ML approaches to unravel complex predictive models.

    Maturity of Digital Twins from an Artificial Intelligence Perspective
    (2024-06-08) Ozturk, Gozde Basak; Brilakis, Ioannis; Celenk, Ozlem; Brilakis, Ioannis [0000-0003-1829-2083]
    Due to its potential to elevate buildings as a system to a level where they turn into cognitive (self-reliant autonomous decision-making and acting) entities, the adoption of Digital Twins (DT) has been significantly increased. Therefore, maturity models have become essential for evaluating and enhancing the advancement in DT to assess the adoption of technology across various industries. The paper proposes a maturity model approach from an Artificial Intelligence (AI) perspective to gain insights into the adoption and implementation of DT in the AEC-FM industry, which distinguishes it from the existing maturity models. Additionally, making a comparison between the interpretation of the term 'cognition' in computer science and its understanding within the AEC-FM industry, presenting pre-classified levels of cognition in literature. In this regard, a literature review is conducted to figure-out the gaps in previous DT maturity model studies. The proposed perspective could cover the missing AI perspective in designing maturity models and provide insights into leveraging the semantics of the term ‘cognitive’ in the AEC-FM industry. Future research directions could further explore various dimensions of DT maturity models and cognition levels within the AEC-FM industry, considering practical challenges and potential applications of DT implementations in-depth.

    Decoding of compressive data pages for optical data storage utilizing FFDNet.
    (Optica Publishing Group, 2024-04-15) He, Zehao; Zhang, Yan; Chu, Daping; Cao, Liangcai; Chu, Daping [0000-0001-9989-6238]
    Coded aperture-based compression has proven to be an effective approach for high-density cold data storage. Nevertheless, its limited decoding speed represents a significant challenge for its broader application. We introduce a novel, to the best of our knowledge, decoding method leveraging the fast and flexible denoising network (FFDNet), capable of decoding a coded aperture-based compressive data page within 30.64 s. The practicality of the method has been confirmed in the decoding of monochromatic photo arrays, full-color photos, and dynamic videos. In experimental trials, the variance between decoded results obtained via the FFDNet-based method and the FFDNet-absent method in terms of average PSNR is less than 1 dB, while realizing a decoding speed enhancement of over 100-fold when employing the FFDNet-based method.
