Electrochemical biosensors are superior technologies that are used to detect or sense biologically and environmentally significant analytes in a laboratory environment, or even in the form of portable handheld or wearable electronics. Recently, imprinted and implantable biosensors are emerging as point-of-care devices, which monitor the target analytes in a continuous environment and alert the intended users to anomalies. The stability and performance of the developed biosensor depend on the nature and properties of the electrode material or the platform on which the biosensor is constructed. Therefore, the biosensor platform plays an integral role in the effectiveness of the developed biosensor. Enormous effort has been dedicated to the rational design of the electrode material and to fabrication strategies for improving the performance of developed biosensors. Every year, in the search for multifarious electrode materials, thousands of new biosensor platforms are reported. Moreover, in order to construct an effectual biosensor, the researcher should familiarize themself with the sensible strategies behind electrode fabrication. Thus, we intend to shed light on various strategies and methodologies utilized in the design and fabrication of electrochemical biosensors that facilitate sensitive and selective detection of significant analytes. Furthermore, this review highlights the advantages of various electrode materials and the correlation between immobilized biomolecules and modified surfaces.

ABSTRACT The central engine in long gamma-ray bursts (GRBs) is thought to be a compact object produced by the core collapse of massive stars, but its exact nature (black hole or millisecond magnetar) is still debatable. Although the central engine of GRB collapsars is hidden to direct observation, its properties may be imprinted on the accompanying electromagnetic signals. We aim to decipher the generic properties of central engines that are consistent with prompt observations of long GRBs detected by the Burst Alert Telescope (BAT) on board the Neil Gehrels Swift Observatory. Adopting a generic model for the central engine, in which the engine power and activity time-scale are independent of each other, we perform Monte Carlo simulations of long GRBs produced by jets that successfully breakout from the star. Our simulations consider the dependence of the jet breakout time-scale on the engine luminosity and the effects of the detector’s flux threshold. The two-dimensional (2D) distribution of simulated detectable bursts in the gamma-ray luminosity versus gamma-ray duration plane is consistent with the observed one for a range of parameter values describing the central engine. The intrinsic 2D distribution of simulated collapsar GRBs peaks at lower gamma-ray luminosities and longer durations than the observed one, a prediction that can be tested in the future with more sensitive detectors. Black hole accretors, whose power and activity time are set by the large-scale magnetic flux through the progenitor star and stellar structure, respectively, are compatible with the properties of the central engine inferred by our model.

A recent special issue of the Classical Receptions Journal marked the twentieth anniversary of the publication of Charles Martindale's Redeeming the Text. Latin Poetry and the Hermeneutics of Reception. Although the rich and various examples of classical reception scholarship that have appeared over the past two decades are by no means all cut from Martindale's cloth, the ‘seminal’ and ‘influential’ nature of his study is surely not in doubt. It is fitting, then, that this issue's round-up of reception publications focuses on a small cluster of recent studies that, like Redeeming the Text, explore the complex reception histories of Latin literature, and do so with a keen eye to the theoretical underpinnings of such scholarship; fitting, too, that our first title, Romans and Romantics, features Charles Martindale among its editors. The eighteen essays in this collection in fact range well beyond literature, with visual culture and the physical fabric of the city of Rome playing an important role; but encounters with Latin texts are a central component of the book, and the overarching theoretical and methodological framework for examining them bears the clear imprint of Martindale's reception manifesto. The introduction emphasizes the importance of remaining alert to the two-way dynamics of reception: not only do the contributors explore the ways in which Romanticism was shaped by antiquity, but they also examine the impact that Romanticism has had on subsequent views of antiquity. Although the idea of reception as a two-way process is often parroted, its implications are not always interrogated and explained so carefully as they are here. Most valuably, Romans and Romantics acknowledges and confronts the overly simple ‘myths’ that attach to our ideas of both the classical and the Romantic, showing how notions of what Romanticism ‘is’ are just as contingent and subject to distortion as those of the classical. So, for example, Timothy Saunders' fascinating chapter on ‘Originality’ successfully challenges the assumption that Romanticism was in some way antithetical or inimical to Roman studies, and that it was responsible for the lasting negative impression of Latin (literary) culture as imitative and inferior. Instead, he argues, ‘Romantic notions of originality’ (85) were more complex than we might assume, and could certainly find space for recognizing and celebrating Rome's creative use of its Greek heritage. Other chapters offer useful studies of the ‘varied, vital, and mutually sustaining’ (v) interactions between Romantics and Romans, including accessible accounts of key authors such as Shelley, Byron, and de Staël. Particularly worthwhile, though, is the final section, ‘Receptions’. By focusing on post-Romantic material, it lays bare our own modern preconceptions of the Romantic movement and encourages contemplation of how receptions of Romanticism are as important as receptions of Rome. Ralph Pite's excellent chapter on Thomas Hardy, for example, shows how this author, and many of his late nineteenth-century contemporaries, might be disappointed by visiting Rome: their expectations of the city, shaped by their own Romantic inheritance, could be undermined by the revelation of the modernized capital of a newly unified Italy, ‘threaten[ing] the post-Romantic traveller's cherished idea of ‘an eternal city frozen in time’’ (328).

AbstractWe examine the role of available information in imprinting processes and investigate how a significant environmental shock can have long‐lasting effects on the future decision‐making of corporate leaders. We argue that information about local infection rates of Severe Acute Respiratory Syndrome (SARS) in 2003 left a pandemic imprint on those who were young adults at that time. The more strongly imprinted corporate leaders would then be more alert to and respond faster to the COVID‐19 outbreak in 2020, a new but similar infectious disease. We study this connection by examining a sample of Chinese publicly traded firms’ initiation of personal protective equipment (PPE) production. We further argue that past informational factors, such as media sentiment regarding the SARS outbreak in 2003, and more recent contemporary informational factors, such as media sentiment about COVID‐19 and online‐reported population mobility from Wuhan, China, where the COVID‐19 outbreak started, influenced the strength of the imprinting effects. Results support our hypotheses, and we discuss contributions to imprinting theory as well as the literature on media in authoritarian regimes.
