Reimagining the future of peer review
Authors: Nixon Aimee 
Published: January 2024

Abstract
The scholarly publishing landscape is in a period of unprecedented transformation. Against the backdrop of international unrest and concerns around sustainability and climate change, publishing is facing its own set of unique challenges. The accelerated transition towards open science, the increasingly interdisciplinary nature of research and the emergence and rapid improvement of new technologies such as Artificial Intelligence (AI) are transforming the way that we discover, consume and perceive research outputs. Peer review remains a critical process at the very heart of the publishing process, and our most powerful tool for evaluating the rigor, credibility, and interest of scholarly research [1]. The first record of an editorial pre-publication peer review dates back to 1665 and to the journal “Philosophical Transactions” [2]. With a history of more than 350 years, the concept of peer review has remained relatively unchanged, but with so many significant changes within the wider publishing industry, visible signs of strain are starting to emerge in the peer review workflow.
A deep reinforcement learning framework to modify LQR for an active vibration control applied to 2D building models
Authors: Gheni Emad Zuhair , Al-Khafaji Hussein M. H. , Alwan Hassan M. 
Published: January 2024

Abstract
Deep reinforcement learning (DRL) has emerged as a promising approach for optimizing control policies in various fields. In this article, we explore the use of DRL for controlling vibrations in building structures. Specifically, we focus on the problem of reducing vibrations induced by external sources such as wind or earthquakes. We propose a DRL-based control framework that learns to adjust the control signal of a classical adaptive linear quadratic regulator (LQR)-based model to mitigate the vibration of building structures in real-time. The framework combines the proximal policy optimization method and a deep neural network that is trained using a simulation environment. The network takes input sensor readings from the building and outputs signals that work as a corrector to the signals from the LQR model. It demonstrates the approach’s effectiveness by simulating a 3-story building structure. The results show that our DRL-based control approach outperforms the classical LQR model in reducing building vibrations. Moreover, we show that the approach is robust for learning the system’s dynamics. Overall, the work highlights the potential of DRL for improving the performance of building structures in the face of external disturbances. The framework can be easily integrated into existing building control systems and extended to other control problems in structural engineering.

Abstract
Decentralized cryptocurrencies have received much attention over the last few years. Bitcoin (BTC) has enabled straight online expenditures without the need for centralized financial institutions. Cryptocurrencies are used not only for online payments but are also increasingly used as financial assets. With the rise in the number of cryptocurrencies, including BTC, Ethereum (ETH), and Ripple (XRP), and the millions of daily trades through different exchange services, cryptocurrency trading is prone to challenges similar to those seen in the traditional financial industry, such as price and trend forecasting, volatility forecasting, portfolio building, and fraud detection. This study examines the use of Recurrent neural networks (RNNs) for predicting BTC, ETH, and XRP prices. Accurate price prediction is essential for investors and traders in this volatile market. Machine learning techniques, including RNNs, Long-Short-Term Memory (LSTM), and convolutional neural networks, have been employed to forecast cryptocurrency prices with varying degrees of success. The aim of this study is to evaluate the effectiveness of RNNs in predicting cryptocurrency prices and compare their performance with other established methods. The results indicate that RNNs, particularly LSTMs and Gated Recurrent Units, demonstrate excellent capabilities in accurately predicting currency prices and providing insights to investors and traders in the cryptocurrency market.

Abstract
In this paper, we explore the spectral properties of unbounded generalized Fredholm operators acting on a non-reflexive Banach space X. The results are formulated in terms of some topological conditions made on X or on its dual

. In addition, we introduce the concept of the so-called g-g-Riesz linear operators as an extension of Riesz operators. The obtained results are used to discuss the incidence of the behavior of generalized essential spectra. Furthermore, a relation between the generalized essential spectrum and the left (resp. the right) essential spectrum by means of g-Riesz perturbation is provided.
On bias reduction in parametric estimation in stage structured development models
Authors: Pham Hoa , Pham Huong T. T. , Yow Kai Siong 
Published: January 2024

Abstract
Multi-stage models for cohort data are popular statistical models in several fields such as disease progressions, biological development of plants and animals, and laboratory studies of life cycle development.
A Bayesian approach on adopting deterministic transformations in the Metropolis–Hastings (MH) algorithm was used to estimate parameters for these stage structured models.
However, the biases in later stages are limitations of this methodology, especially the accuracy of estimates for the models having more than three stages.
The main aim of this paper is to reduce these biases in parameter estimation.
In particular, we conjoin insignificant previous stages or negligible later stages to estimate parameters of a desired stage, while an adjusted MH algorithm based on deterministic transformations is applied for the non-hazard rate models.
This means that current stage parameters are estimated separately from the information of its later stages.
This proposed method is validated in simulation studies and applied for a case study of the incubation period of COVID-19.
The results show that the proposed methods could reduce the biases in later stages for estimates in stage structured models, and the results of the case study can be regarded as a valuable continuation of pandemic prevention.
Spatial signature of the photoelastic effect in the acoustic–plasmonic coupling revealed by space responsivity induced by polarized optical excitation

Published: January 2024

Abstract
Acoustic–plasmonic coupling in metallic nanoparticles can significantly alter their optical absorption and scattering characteristics. However, almost all previous investigations on acoustic–plasmonic coupling so far have been focused on the spectral response of particles in a vacuum. In this report, a spatial photon scattering mode taking count in the acoustic–plasmonic coupling of individual gold nanoparticle (GN) on a silicon substrate under ultrasonic influence was presented. The acoustic–plasmonic is visualized with parametric images with spatial scattering patterns of the particle under the excitation of polarized light along the Poincare’s equatorial trajectory. The ultrasonic sources can be sensitively extracted from the parametric sinδ images, providing clear evidence of the extremely weak influence of ultrasound wave directivity on the spatial characteristics of the scattering of the particle through acoustic–plasmonic coupling. Experiment and simulation results reveal that, in general, the coupling is the strongest, when the maximum electric field (plasmon vibration mode) aligns with the ultrasonic propagation direction. This study provides a new angle to observe and deepen the understanding of the acoustic–plasmonic effect of nanoparticles, in addition to the conventional manner of investigation on their scattering spectra. It emphasizes the possibility of determining the spatial distribution of nanoparticles via photon state scattering when they are in a weakly oscillating environment, providing valuable guidance for future potential applications exploiting the acoustic–plasmonic effect of nanostructures.
Melting-free integrated photonic memory with layered polymorphs
Authors: Ullah Kaleem , Li Qiu , Li Tiantian , Gu Tingyi 
Published: January 2024

Abstract
Chalcogenide-based nonvolatile phase change materials (PCMs) have a long history of usage, from bulk disk memory to all-optic neuromorphic computing circuits. Being able to perform uniform phase transitions over a subwavelength scale makes PCMs particularly suitable for photonic applications. For switching between nonvolatile states, the conventional chalcogenide phase change materials are brought to a melting temperature to break the covalent bonds. The cooling rate determines the final state. Reversible polymorphic layered materials provide an alternative atomic transition mechanism for low-energy electronic (small domain size) and photonic nonvolatile memories (which require a large effective tuning area). The small energy barrier of breaking van der Waals force facilitates low energy, fast-reset, and melting-free phase transitions, which reduces the chance of element segregation-associated device failure. The search for such material families starts with polymorphic In2Se3, which has two layered structures that are topologically similar and stable at room temperature. In this perspective, we first review the history of different memory schemes, compare the thermal dynamics of phase transitions in amorphous-crystalline and In2Se3, detail the device implementations for all-optical memory, and discuss the challenges and opportunities associated with polymorphic memory.
Boris Pahor’s Urban Miniature: Conducting the City as an Open-Ended Score
Authors: Solioz Christophe 
Published: January 2024

Abstract
Against the background of an introductory note on Boris Pahor’s writings, this contribution focuses on one particular example of his work. It is an urban miniature that blurs the boundaries between literary, musical, and architectural writing—and from mutually antagonistic positions it converges towards some measure of coherence. Pahor explores the urban space by conceiving it as an open-ended musical score, but combining poetry, music, film, and architecture to pave the way for a new kind of investigation of the urban space. Removed from centralized and object-defined urbanism, the action and context-related city is experienced differently, as a space of possibility, as if it were itself a creative process amounting to a performance. That viewpoint corresponds to a shift from the ontological “what” to the performance of “how”, and demands acknowledgement of the city’s state of constant change, shaped by its users’ agency.

Authors: Yarahuan Julia K.W. , Kisvarday Susannah , Kim Eugene , Yan Adam P. , Nakamura Mari M. , Jones Sarah B. , Hron Jonathan D. 
Published: January 2024

BACKGROUND AND OBJECTIVE:
This study aimed to develop and evaluate an algorithm to reduce the chart review burden of improvement efforts by automatically labeling antibiotic selection as either guideline-concordant or -discordant based on electronic health record data for patients with community-acquired pneumonia (CAP).

METHODS:
We developed a 3-part algorithm using structured and unstructured data to assess adherence to an institutional CAP clinical practice guideline. The algorithm was applied to retrospective data for patients seen with CAP from 2017 to 2019 at a tertiary children’s hospital. Performance metrics included positive predictive value (precision), sensitivity (recall), and F1 score (harmonized mean), with macro-weighted averages. Two physician reviewers independently assigned “actual” labels based on manual chart review.

RESULTS:
Of 1345 patients with CAP, 893 were included in the training cohort and 452 in the validation cohort. Overall, the model correctly labeled 435 of 452 (96%) patients. Of the 286 patients who met guideline inclusion criteria, 193 (68%) were labeled as having received guideline-concordant antibiotics, 48 (17%) were labeled as likely in a scenario in which deviation from the clinical practice guideline was appropriate, and 45 (16%) were given the final label of “possibly discordant, needs review.” The sensitivity was 0.96, the positive predictive value was 0.97, and the F1 was 0.96.

CONCLUSIONS:
An automated algorithm that uses structured and unstructured electronic health record data can accurately assess the guideline concordance of antibiotic selection for CAP. This tool has the potential to improve the efficiency of improvement efforts by reducing the manual chart review needed for quality measurement.

Authors: Yoo Changmin 
Published: January 2024

AbstractBackground and aimsThe current research aimed to discover classification concerning problematic smartphone use in children. Furthermore, to investigate their longitudinal trajectories, as well as to discover the connection concerning problematic smartphone usage by individual, parental, and school factors.MethodsA total of 2,399 South Korean children who were in the 4th grade (female 1,206 (50.3%), age 10–13 years) at baseline. Latent class growth analysis was utilized to discover typologies in problematic smartphone use and their longitudinal trajectories. Multinomial logistic regression analysis was used to find various associations among problematic smartphone use and individual, parental, as well as school factors.ResultsThe results identified three distinct trajectories of problematic smartphone use: (1) a high-level group (7.7%), (2) a mid-increasing group (62.5%), and (3) a low-increasing group (29.8%). The increasing group showed the highest level of problematic smartphone use. Gender, self-esteem, social withdrawal, exercise, parental inconsistency, monthly income, and teacher support were significant predictors.Discussion and ConclusionsThe findings suggest that there are distinct developmental trajectories concerning problematic smartphone usage of childhood. The results show that the early discovery of children in danger of problematic smartphone use and targeted interventions aimed at reducing parental inconsistency and social withdrawal, improving self-esteem, exercise, and teacher support may be effective strategies for preventing problematic smartphone usage during childhood.

Authors: Da Silva Muniz Marilia , Amoedo Celestino amorim 
Published: January 2024

Resumo
Os idosos precisam de assistência social e prioridade médica. É importante monitorar a independência dos idosos no seu dia a dia e respeitá-los como seres humanos. O objetivo foi analisar o nível de independência nas atividades de vida diária (AVD) de um grupo de idosos residentes em ILPI (Instituições de Longa Permanência para Idosos). Participaram deste estudo onze idosos com 60 anos ou mais. Trata-se de um estudo quantitativo descritivo que estabelece associações entre variáveis como sexo, idade, atividades recreativas e de lazer, problemas de saúde e autopercepção. Dados obtidos do questionário e estatística descritiva foram utilizados para os cálculos. Descobrimos que a condição de independência dos idosos nas atividades de lazer não afeta a sua capacidade de estabilizar ou reverter o declínio da atividade física relacionado com a idade. Sabemos que problemas de saúde podem influenciar o mau desempenho nas AVD. No entanto, os idosos portadores de patologias possuem autonomia em realizar algumas das AVD’s, de forma independente, porém, os homens mais velhos apresentam maior independência em comparação com as mulheres, e aqueles com idade entre 80 e 89 anos são mais independentes do que aqueles com idade entre 70 e 79 anos. Idosos de ambos os sexos apresentam percepção de sua independência e habilidades motoras reduzidas na realização de determinadas AVD, principalmente entre aqueles com idade entre 80 e 89 anos.
