DifFuzzAR: automatic repair of timing side-channel vulnerabilities via refactoring
Authors: Lima Rui , Ferreira João F. , Mendes Alexandra , Carreira Carolina 
Published: October 2023

AbstractVulnerability detection and repair is a demanding and expensive part of the software development process. As such, there has been an effort to develop new and better ways to automatically detect and repair vulnerabilities. DifFuzz is a state-of-the-art tool for automatic detection of timing side-channel vulnerabilities, a type of vulnerability that is particularly difficult to detect and correct. Despite recent progress made with tools such as DifFuzz, work on tools capable of automatically repairing timing side-channel vulnerabilities is scarce. In this paper, we propose DifFuzzAR, a tool for automatic repair of timing side-channel vulnerabilities in Java code. The tool works in conjunction with DifFuzz and it is able to repair 56% of the vulnerabilities identified in DifFuzz’s dataset. The results show that the tool can automatically correct timing side-channel vulnerabilities, being more effective with those that are control-flow based. In addition, the results of a user study show that users generally trust the refactorings produced by DifFuzzAR and that they see value in such a tool, in particular for more critical code.
A Comparative Study of the Human-Nature Relationship in The Fate of Fausto and I’ll Sow My Hands in the Garden
Authors: Zekavat Massih 
Published: October 2023

Abstract
This article contends that the representation of human-nature relationship in children’s literature can map onto its gender politics through a comparative study of multimodal dynamics of Irish and Persian picturebooks. It builds upon the premise that children’s literature can play a significant role in sustainable education and forming pro-environmental values in the process of socialization during childhood. Oliver Jeffers’ The Fate of Fausto: A Painted Fable (2019) and Hoda Hadadi’s I’ll Sow My Hands in the Garden (2020) are examined within the framework of environmental humanities for their verbal and pictorial depictions of the human-nature relationship. The findings convey that characters’ gender and sexual identities can impact their interactions with nature; at the same time, nature can clear a space for expressing and affirming underrepresented and historically marginalized gender and sexual identities in children’s literature through creative and dynamic multimodal interactions between the text and illustrations. A comparative analysis reveals that Jeffers challenges abstract, absolute masculinity and masculine arrogance and calls for reforming the notion of need in modern societies, while more playful and transgressive dynamics between the text and illustrations provide an effective tool for Hadadi who appropriates the poetry of Forugh Farrokhzad, a maverick female writer, to undermine the plots of male homo-sociality and erotic counterplotting with a subversive alternative to heteropatriarchy and anthropocentrism.
Multi-level control for multiple mobile robot systems

Published: October 2023

AbstractThis paper contributes with a multi-level, hierarchical control system for a fleet of mobile robots sharing a common 2D motion space. The system consists of three levels, with the top level being a supervisor based on a discrete representation of the Multiple Mobile Robot System (MMRS), in which robot motion processes are seen as sequences of stages. The supervisor controls centrally the changes of their stages by robots, ensuring their collision-, and deadlock-free concurrent movement. The intermediate control level supervises locally the execution of robot motion on individual stages in a manner consistent with the decisions of the top level. The lowest level, robot control, is responsible for motion execution as determined by the local supervisor. We capitalize on some earlier results concerning the supervisory control of MMRS and propose a common framework for three supervisory control models. Then we propose relevant solutions for the local supervisors, in particular, a DES-based robot-motion-mode control and application of the Artificial Potential Field model for ensuring collision-free motion of two robots sharing a space sector. Next we assume simple robot control and subject the system to simulation experiments aimed at comparing the impact of the different solutions on the performance of MMRS.
The Effect of Natural Disasters on Hotel Demand, Supply and Labour Markets: Evidence from the La Palma Volcano Eruption
Authors: Leoni Veronica , Boto-García David 
Published: October 2023

AbstractNatural disasters are an important deterrent factor for tourism activities from both supply and demand perspectives. This paper studies the short-term effect of a volcano eruption on hotel demand, supply and hospitality labour in La Palma (Spain), an island economy that is highly dependent on the tourism sector. Based on a monthly panel dataset, we employ seemingly unrelated difference-in-differences (SUR-DiD) to identify the distinct responses of these three outcomes both during and post eruption. We are particularly interested in examining the asymmetry in their elasticities to the shock, which serve as indicators of disaster resilience. Potential spillover effects on nearby islands are also examined. We find that the eruption resulted in significant yet asymmetrical drops in international demand, number of hotels opened, and hospitality workers hired. Our findings inform about the resilience of the tourism industry to natural disasters, offering relevant insights about heterogeneous effects depending on exposure to the event.
Dual-Band (28/38 GHz) Compact MIMO Antenna System for Millimeter-Wave Applications
Authors: Elsharkawy Rania R. , Hussein Khalid.F. A. , Farahat Asmaa E. 
Published: October 2023

AbstractThe present work proposes a novel design of a dual-band-printed antenna for operation at the millimeter-wave frequencies 28 and 38 GHz that are utilized for the modern and future generations of mobile communications. The antenna is composed of two radiating elements. The first element is the main patch that is fed through a microstrip line with inset feed, and the second element is a parasitic element that is fed through capacitive coupling with the main patch. The design parameters of the proposed antenna are optimized through a complete parametric study to give excellent impedance matching at 28 GHz over the band 27.7–28.3 GHz and at 38 GHz over the band 37.7–38.3 GHz. The surface current distributions at the two operational frequencies are investigated. The designed antenna is used to construct a four-port efficient multi–input–multi–output (MIMO) system. The MIMO system performance is investigated regarding the envelope correlation coefficient (ECC), diversity gain (DG), and the channel capacity loss (CCL) showing very good performance. The single-element antenna and the MIMO are fabricated and experimentally evaluated showing excellent impedance matching over the lower and higher frequency bands, which come in agreement with the simulation results. It is shown that the antenna produces maximum gain of 7.4 and 8.1 dBi at 28 and 38 GHz, respectively. The average radiation efficiencies of the proposed antenna are 88% and 88.8% over the lower and higher frequency bands, respectively. In addition, the coupling coefficients between the MIMO antenna systems are measured experimentally showing very low coupling values resulting in an efficient MIMO system that is suitable for future millimeter-wave (mm-wave) applications.

Published: October 2023

Abstract
Purpose
To describe the epidemiology, indications and surgical results of pars plana vitrectomy (PPV) in patients over 85 years of age.

Methods
A retrospective cohort study was performed including all consecutive patients aged 85 years or older who underwent PPV between September 2018 and March 2022 in a single hospital in Madrid, Spain. Data on diagnosis, comorbidities, surgical indication, surgical details, surgical complications and surgical outcomes were collected from medical records.

Results
A total of 124 eyes of 119 patients (56 males, 47.1%) underwent PPV. Median age was 87 years (range 85–96). The most common surgical indications were complications of cataract surgery in 34 patients (28.6%), macular epiretinal membrane in 32 (26.9%), and rhegmatogenous retinal detachment (RRD) in 12 (10.1%). Mean preoperative best corrected visual acuity (BCVA) was 13.33 ± 42.34 ETDRS letters and improved to 40.05 ± 41.04 letters at 3 months (p < 0.001). BCVA had improved in 68.82% of patients at 3 months. Patients with chronic kidney disease (CKD; p < 0.001), RRD (p = 0.003), ocular trauma (p = 0.001) and age-related macular degeneration (AMD; p = 0.002) showed worse BCVA at 3 months from surgery. Patients with better preoperative BCVA (p < 0.001), and those who underwent 25G PPV (p = 0.041) showed better visual outcomes.

Conclusions
PPV is an effective technique for improving visual acuity in patients aged 85 years and older with vitreoretinal diseases. Visual outcomes were better when patients had a better preoperative visual acuity and underwent 25G PPV. Patients with a previous diagnosis of AMD or CKD, and those undergoing surgery for ocular trauma or RRD had worse visual outcomes.
Measuring the mediating effect of satisfaction and compatibility on the relationship between podcast features and users’ intention of continuous usage and word of mouth

Published: October 2023

AbstractAmid the expanding podcast market, a myriad of podcasters and advertisers have ventured into hosting and endorsements. The paramount objective of this research was to ascertain the moderating roles of satisfaction (SAT) and Compatibility (COM) in the relationship between podcast characteristics and the Continued Use Intention (CUI) of users. To assess the ramifications of podcast attributes—technology affinity (TA), perceived playfulness (PP), multitasking (MT), social presence (SP), SAT, and COM—on Word of Mouth Intention (WOMI) and CUI, a questionnaire was disseminated among seasoned podcast users. From an aggregate of 250 returned questionnaires, 227 were adjudged as valid post invalidation scrutiny, yielding a 90% retention quotient. Employing the Structural Equation Modeling (SEM) approach for data analysis, the findings revealed the following: TA positively influenced both SAT and COM; PP favorably influenced SAT; MT cast a positive impact on COM; SP constructively affected both SAT and COM; COM positively influenced SAT; and WOMI constructively impacted CUI. This research propounds that podcast platforms might metamorphose into voice-anchored social platforms by curating compelling content, interweaving interactive constituents such as inducements or contests, and galvanizing listener engagement. We advocate for listeners’ indulgence in classical or ambient music during engagements, without requiring excessive focus on the host’s content.
When ‘Enough and as Good’ is Not Good Enough
Authors: Spafford Jesse 
Published: October 2023

AbstractUnder what circumstances can people convert natural resources into private property? John Locke famously answered this question by positing what has become known as the Lockean proviso: a person has the power to unilaterally appropriate natural resources ‘at least where there is enough and as good left in common for others’. This Lockean proviso has been widely embraced by right-libertarians who maintain that a relevant act appropriates only if others are not left worse off. However, this proviso is multiply ambiguous with there being various ways of specifying its distinct elements. Daniel Attas has argued that all proposed specifications render the proviso either implausible or unsatisfied. However, there are three seemingly plausible specifications that he either fails to consider or does not adequately address. This paper attempts to show that these specifications are either unacceptable, go unsatisfied, or fail to support right-libertarianism.
In the Eye of Transformer: Global–Local Correlation for Egocentric Gaze Estimation and Beyond

Published: October 2023

AbstractPredicting human’s gaze from egocentric videos serves as a critical role for human intention understanding in daily activities. In this paper, we present the first transformer-based model to address the challenging problem of egocentric gaze estimation. We observe that the connection between the global scene context and local visual information is vital for localizing the gaze fixation from egocentric video frames. To this end, we design the transformer encoder to embed the global context as one additional visual token and further propose a novel global–local correlation module to explicitly model the correlation of the global token and each local token. We validate our model on two egocentric video datasets – EGTEA Gaze + and Ego4D. Our detailed ablation studies demonstrate the benefits of our method. In addition, our approach exceeds the previous state-of-the-art model by a large margin. We also apply our model to a novel gaze saccade/fixation prediction task and the traditional action recognition problem. The consistent gains suggest the strong generalization capability of our model. We also provide additional visualizations to support our claim that global–local correlation serves a key representation for predicting gaze fixation from egocentric videos.

Published: October 2023

AbstractSince real-world training datasets cannot properly sample the long tail of the underlying data distribution, corner cases and rare out-of-domain samples can severely hinder the performance of state-of-the-art models. This problem becomes even more severe for dense tasks, such as 3D semantic segmentation, where points of non-standard objects can be confidently associated to the wrong class. In this work, we focus on improving the generalization to out-of-domain data. We achieve this by augmenting the training set with adversarial examples. First, we learn a set of vectors that deform the objects in an adversarial fashion. To prevent the adversarial examples from being too far from the existing data distribution, we preserve their plausibility through a series of constraints, ensuring sensor-awareness and shapes smoothness. Then, we perform adversarial augmentation by applying the learned sample-independent vectors to the available objects when training a model. We conduct extensive experiments across a variety of scenarios on data from KITTI, Waymo, and CrashD for 3D object detection, and on data from SemanticKITTI, Waymo, and nuScenes for 3D semantic segmentation. Despite training on a standard single dataset, our approach substantially improves the robustness and generalization of both 3D object detection and 3D semantic segmentation methods to out-of-domain data.

Published: October 2023

AbstractFunctional decline of physiological systems during ageing leads to age-related diseases. Dietary glycine increases healthy lifespan in model organisms and might decrease inflammation in humans, suggesting its geroprotective potential. This review summarises the evidence of glycine administration on the characteristics of eleven physiological systems in adult humans. Databases were searched using key search terms: ‘glycine’, ‘adult’, ‘supplementation’/ ‘administration’/ ‘ingestion’/ ‘treatment’. Glycine was administered to healthy and diseased populations (18 and 34 studies) for up to 14 days and 4 months, respectively. The nervous system demonstrated the most positive effects, including improved psychiatric symptoms from longer-term glycine administration in psychiatric populations. While longer-term glycine administration improved sleep in healthy populations, these studies had small sample sizes with a high risk of bias. Larger and long-term studies with more robust study designs in healthy populations to examine the effects of glycine administration on preventing, delaying or reversing the ageing process are warranted.

Published: October 2023

ZusammenfassungDie Einführung des 9‑Euro-Tickets (9ET) im Sommer 2022 stellte für Politik und Forschung ein aufschlussreiches Realexperiment dar. Wir untersuchen auf Basis von Daten aus einer bundesweiten Online-Befragung im Juli 2022 (1347 Befragte, quotiert), wer das Ticket nachgefragt und wie sich die Mobilität gruppenspezifisch verändert hat. Dabei legen wir den Fokus auf Einkommens- und Stadt-Land-Unterschiede: Wurden insbesondere niedrige Einkommensgruppen durch das 9ET finanziell entlastet? Welche regionalen Unterschiede sind in der Nutzung allgemein und für den Umstieg von motorisiertem Individualverkehr auf den ÖPNV zu beobachten? Inwieweit sind diese Unterschiede durch die in städtischen und ländlichen Regionen unterschiedliche ÖPNV-Infrastruktur bedingt? Unsere Daten zeigen, dass das 9ET von niedrigen Einkommensgruppen etwas und von Bewohnern von Großstädten deutlich häufiger genutzt wurde als von anderen Gruppen. Auch von der Umwandlung von ÖPNV-Zeitkarten in ein günstigeres 9ET und der entsprechenden Kostenerstattung profitierten diese beiden Bevölkerungsgruppen besonders. Der Effekt der Wohnlage bleibt unter statistischer Kontrolle soziodemografischer Variablen bestehen, schwächt sich aber mit Berücksichtigung der Qualität der ÖPNV-Infrastruktur deutlich ab. Neben zusätzlichen Fahrten kam es auch zur Substitution von Autofahrten: Etwa 10 % der Befragten in unserem Sample gaben an, die Pendelstrecke vom Auto (als Verkehrsmittel der Wahl im Mai) mit Gültigkeit des 9ET im Juni auf den ÖPNV umgestellt zu haben. Auch dies betrifft vornehmlich Stadtbewohner, während im ländlichen Raum der schlechtere Ausbau der ÖPNV-Infrastruktur eine Barriere darstellte.
Profile-based latent class distance association analyses for sparse tables:application to the attitude of European citizens towards sustainable tourism
Authors: Bassi Francesca , Vera José Fernando , Marmolejo Martín Juan Antonio 
Published: October 2023

AbstractSocial and behavioural sciences often deal with the analysis of associations for cross-classified data. This paper focuses on the study of the patterns observed on European citizens regarding their attitude towards sustainable tourism, specifically their willingness to change travel and tourism habits to be more sustainable. The data collected the intention to comply with nine sustainable actions; answers to these questions generated individual profiles; moreover, European country belonging is reported. Therefore, unlike a variable-oriented approach, here we are interested in a person-oriented approach through profiles. Some traditional methods are limited in their performance when using profiles, for example, by sparseness of the contingency table. We removed many of these limitations by using a latent class distance association model, clustering the row profiles into classes and representing these together with the categories of the response variable in a low-dimensional space. We showed, furthermore, that an easy interpretation of associations between clusters’ centres and categories of a response variable can be incorporated in this framework in an intuitive way using unfolding. Results of the analyses outlined that citizens mostly committed to an environmentally friendly behavior live in Sweden and Romania; citizens less willing to change their habits towards a more sustainable behavior live in Belgium, Cyprus, France, Lithuania and the Netherlands. Citizens preparedness to change habits however depends also on their socio-demographic characteristics such as gender, age, occupation, type of community where living, household size, and the frequency of travelling before the Covid-19 pandemic.

Published: October 2023

AbstractThis study assessed the effectiveness of using video cameras mounted on commercial trawls for a deep-sea lobster, the New Zealand scampi Metanephrops challengeri, for acquiring information on habitat associations of demersal species and fishing efficiency. Randomly selected frames from 1 h of recording replicated over 12 trawls and conducted over three fisheries management areas (FMA), were analysed for counts of visible scampi, scampi burrows, visible topographical features and visible epifauna and fish taxa. Poisson regression analysis indicated a positive relationship between the distribution of scampi burrows (a proxy of scampi abundance) and conical mounds (formed by bioturbators), but a negative relationship with smooth topography. Counts of scampi burrows were also positively associated with counts of visible scampi for four trawls, while significant relationships were seldom found between counts of scampi burrows and other commonly observed individual taxa. Scampi trawl efficiency was low, with only 56 of the 186 observed scampi (30%) passing over the footrope and into the trawl net. The results confirm the effectiveness of video sampling from commercial trawls to improve our understanding of habitats and fishing efficiency in deep-sea fisheries.
Reaction microkinetic model of xylose dehydration to furfural over beta zeolite catalyst

Published: October 2023

Abstract
In recent decades, there has been a growing interest in bio-refineries as a crucial element in transitioning to a low-carbon economy. One specific aspect of this interest is the conversion of carbohydrates into separate platform chemicals, such as furfural (FUR), which play a significant functional role in various daily life processes. This research paper focuses on investigating the use of a H-beta catalyst with SiO2/Al2O3 = 28 for producing furfural from xylose in water. Various conditions, such as temperature and initial solution concentration, are studied to determine their effect on FUR yield. The highest FUR yield (40 mol.%) is obtained when FUR is the only product species. We also report that about 90% yield from reaction with fresh catalyst can be achieved after catalyst regeneration. The activation energies for the reaction on the catalyst surface are found to be in the range of 38–75 kJ/mol. A mathematical kinetic model with three irreversible steps is derived to estimate the reaction sequence at 160, 180, and 200 °C. The model takes into account mechanisms such as adsorption, desorption, and transport (internal or external). Our results suggest that the H-beta catalyst shows high activity toward FUR yield and could be a promising alternative for mass-scale production of the latter.
