Malicious clouds coalition management for business processes deployment
Authors: Ahmed Nacer Amina , Abdmeziem Mohammed Riyadh , Aid Asma 
Published: March 2024

AbstractCloud computing has raised concerns about security, causing many companies to hesitate in adopting it. Despite these concerns, there are methods available to address the risks associated with implementing a business process (BP) in the cloud. One common approach involves breaking down the BP model into smaller fragments, allowing each cloud provider access to a specific part of the overall model. However, this method fails to protect against collaboration between malicious cloud providers, which, by pooling their knowledge, can exploit the logic of the process. To tackle this issue, our paper proposes an approach that effectively manages coalitions when they arise. To do this, we introduce observer and deceiver fragments, which play a crucial role in redirecting the process execution toward a fake task. This strategic redirection prevents access to important information. The obtained results demonstrate that our proposed solution enhances security, mitigates risks, and does not necessarily lead to higher costs compared to other methods based solely on splitting.
Cracking and failure mode behavior of hybrid FRP strengthened RC column members under flexural loading
Authors: Balla Taraka M. R. , Prakash S. Suriya 
Published: March 2024

AbstractStrengthening of reinforced concrete (RC) members in bridges and buildings is often required to improve flexural performance. Strengthening using fiber‐reinforced polymer (FRP) composites has become popular as FRPs offer multiple advantages compared with conventional strengthening practices like steel jacketing and concrete enlargement. External bonding (EB) using carbon FRP (CFRP) laminates/fabric has become a common strengthening practice. The effectiveness of the EB strengthened system is reduced due to possible debonding of FRP from concrete substrate. The near‐surface mounting (NSM) of FRP laminates is efficient in reducing the debonding failure, but it is not effective under dominant compression loading. Hybrid FRP (HYB) strengthening combines the advantages of both the NSM and EB techniques. HYB strengthening can enhance the performance of RC members under all loading combinations. The main objective of this study is to understand the flexural crack opening behavior of control and hybrid FRP strengthened RC column members under pure bending. The digital image correlation (DIC) analysis shows that the crack width and its propagation are significantly reduced due to hybrid FRP strengthening. The crack widths measured using the DIC are compared with the analytical predictions based on Eurocode 2 and fib bulletin 90. HYB FRP strengthening increased the strength and post‐cracking stiffness of RC elements under flexure without compromising the ductility. In addition, the HYB strengthening distributed the damage under flexural loading, unlike localized damage observed in control RC elements.

AbstractBackgroundRenal cysts are common in clinical practice, but some may harbor rare pathological entities such as mixed epithelial and stromal tumors (MEST). Imaging studies are crucial for accurate diagnosis. While laparoscopic deroofing is an established approach for symptomatic renal cysts, encountering MEST within a cyst is uncommon.Case PresentationWe present the case of a 37‐year‐old female who presented with persistent left flank pain. Imaging revealed a large renal cyst in the lower pole of the left kidney, classified as Bosniak 2. Despite analgesia, the patient's symptoms persisted, leading to a laparoscopic deroofing procedure. Histopathological examination postprocedure revealed a MEST. The patient reported complete resolution of symptoms at the 3‐month follow‐up.ConclusionThis unique case presents the successful identification and surgical management of a MEST masquerading as a lower pole renal cyst through laparoscopic deroofing. It also contributes to the existing literature by highlighting the importance of considering rare pathological entities in the evaluation of renal cysts and the value of laparoscopic techniques in their management.
Enabling policy environment for water operator partnerships in the Southern African Development Community

Published: March 2024

AbstractWater service provision has typically been primarily regarded as a government endeavor, especially in developing countries. Various concepts of partnerships have been promoted over the past five decades in the sector, primarily to improve service provision. Among these partnerships, water operator partnerships (WOPs) have been distinguished as a leading concept that promotes easy access to water supply and sanitation. Several WOPs exist worldwide with varying partnership types and characteristics. For WOPs to thrive effectively globally, an enabling environment has to be provided. More so for developing countries that are more susceptible to socio‐economic and climate change factors that affect water service delivery. This paper evaluates the enabling policy environment for WOPs in the Southern African Development Community (SADC) region. Data used for the study include literature from the Global Water Operator Partnerships Alliance (GWOPA) WOPs database, as well as other online resources, enabling a detailed understanding of different case studies in the SADC region on a North–South and South–South basis. It must, however, be noted that data availability on the database is dependent on the utilities engaged in the WOP recording and uploading it, and this affected the scope of the study. The database provided three in‐depth case studies from Mozambique, Tanzania, and Zimbabwe, and extensive literature review provided an additional in‐depth case study from Malawi. Strategies such as water reforms and multi‐stakeholder partnerships are highlighted in aiding the WOPs. Findings show that current policies in the region make provisions for partnerships but are not explicit or exhaustive on the different forms of partnerships. The lack of an intermediate third party in countries such as Malawi negatively affects the relationship between the utilities and, subsequently, the success of the WOP. Strategies such as capacity building and stakeholder participation can assist in creating a more enabling policy environment for WOPs.

AbstractNon‐Newtonian fluid plays a vital role in the field of manufacturing and engineering sector, because of its immense heat transfer rate. The two‐dimensional incompressible unsteady Maxwell nanofluid thin‐film flow with MHD and viscous dissipation over an inclined surface is investigated. One of the mechanisms in the second law of thermodynamics, that is irreversibility which also analyzed. The Maxwell nanofluid thin film energy and motion equations in the additional information have been turned into a coupled differential system of the third order. The transformed ODE equations are further evaluated by using the Homotopy Analysis Method (HAM). The variations of entropy rate, velocity, Bejan number and temperature field with the various emerging parameters are analyzed. This could potentially lead to the development of solar energy systems that are both affordable and highly efficient, so enabling the more efficient use of renewable energy sources and reducing our dependence on fossil fuels.
The ʻGlamorgan School of Translationʼ: A No Politics Phenomenon?
Authors: Parina Elena 
Published: March 2024

AbstractThis article endeavours to assess issues of politics and policies related to a particular group of texts said to have been produced in South Wales in the second half of the sixteenth century within the so-called Glamorgan school of translation. There are doubts that all of the texts listed by G. J. Williams are indeed products of a single “school” of translators. For three particular texts—the translations of The Voyage of the Wandering Knight, Dives et Pauper, and Gesta Romanorum—some generalizations about a late sixteenth century Glamorgan textual community might be attempted. It could be suggested that the selection mechanisms at work in this culture of translation were steered by the conservatism of the target audience. This is reflected in both the language and the style of the works, as well as by trends in the choice of source texts for translation. For originals of the two texts, Gesta Romanorum and Diues and Pauper were composed before the Reformation. How exactly their confessional fluidity should be interpreted remains a question. It is unlikely that what we see here is a sign of religious toleration in the modern sense. However, these examples of “simple and generally acceptable Christian piety” might be investigated further as landmarks in the complex dynamics of confessional identities in a peripheral region during a turbulent era in British history.

ZusammenfassungDas Mutterschutzgesetz soll die Mutter und das Kind vor Gefahren, Überforderung und Gesundheitsschädigung am Arbeitsplatz ebenso wie vor finanziellen Einbußen und dem Verlust des Arbeitsplatzes schützen. Allerdings werden die mit dem Mutterschutzgesetz definierten Ziele der Sicherheit und Gesundheit der schwangeren Mitarbeiterin einerseits und der Verhinderung von Benachteiligungen im Berufsleben andererseits derzeit auf der Intensivstation noch nicht ausreichend erfüllt. Es sollte eine für alle Beteiligten gewinnbringende Umsetzung des Mutterschutzgesetzes auch in den in der DIVI vertretenen Fachbereichen vorangetrieben werden, insbesondere das Arbeiten von Schwangeren im ärztlichen und Pflegefachpersonal sowie in weiteren Gesundheitsfachberufen (Atmungstherapie, Physiotherapie, Logopädie, Psychologie und Sozialdienst) auf Intensivstationen. Es soll dafür sensibilisiert werden, jede schwangere und stillende Mitarbeiterin individuell zu betrachten und gemeinsam eine persönliche Lösung für die Weiterbeschäftigung auch während der Schwangerschaft auf der Intensivstation zu erarbeiten. Es werden mögliche Wege und Lösungen zur Erreichung dieses Ziels skizziert und Praxisbeispiele zur Umsetzung im klinischen Alltag gegeben. Diese basieren auch auf einer umfangreichen Darstellung von Tätigkeiten nach einem Ampelsystem für alle Berufsgruppen. Aspekte, die gegen die Beschäftigung einer schwangeren Mitarbeiterin auf der Intensivstation sprechen oder diese einschränken, werden diskutiert und potenzielle Lösungsoptionen aufgezeigt.

Abstract

Background and objective
This study aims to define specific measurements on cranial high-resolution computed tomography (HRCT) images prior to surgery to prove the feasibility of the navigated transmastoid infralabyrinthine approach (TI-A) without rerouting of the facial nerve (FN) and decompression of the jugular bulb (JB) in accessing the extradural-intrapetrous part of petrous bone lesions located at the petrous apex and petroclival junction.

Materials and methods
Vertical and horizontal distances of the infralabyrinthine space were measured on cranial HRCT images prior to dissection. Subsequently, the area of access was measured on dissected human cadaveric specimens. Infralabyrinthine access to the extradural part of the petrous apex and petroclival junction was evaluated on dissected specimens by two independent raters. Finally, the vertical and horizontal distances were correlated with the area of access.

Results
Fourteen human cadaveric specimens were dissected bilaterally. In 54% of cases, the two independent raters determined appropriate access to the petrous apex and petroclival junction. A highly significant positive correlation (r = 0.99) was observed between the areas of access and the vertical distances. Vertical distances above 5.2 mm were considered to permit suitable infralabyrinthine access to the extradural area of the petrous apex and petroclival junction.

Conclusions
Prior to surgery, vertical infralabyrinthine distances on HRCT images above 5.2 mm provide suitable infralabyrinthine access to lesions located extradurally at the petrous apex and petroclival junction via the TI-A without rerouting of the FN and without decompression of the JB.

Published: March 2024

AbstractArchitectural parameters of skeletal muscle such as pennation angle provide valuable information on muscle function, since they can be related to the muscle force generating capacity, fiber packing, and contraction velocity. In this paper, we introduce a 3D ultrasound-based workflow for determining 3D fascicle orientations of skeletal muscles. We used a custom-designed automated motor driven 3D ultrasound scanning system for obtaining 3D ultrasound images. From these, we applied a custom-developed multiscale-vessel enhancement filter-based fascicle detection algorithm and determined muscle volume and pennation angle. We conducted trials on a phantom and on the human tibialis anterior (TA) muscle of 10 healthy subjects in plantarflexion (157 ± 7$$^\circ$$

∘

), neutral position (109 ± 7$$^\circ$$

∘

, corresponding to neutral standing), and one resting position in between (145 ± 6$$^\circ$$

∘

). The results of the phantom trials showed a high accuracy with a mean absolute error of 0.92 ± 0.59$$^\circ$$

∘

. TA pennation angles were significantly different between all positions for the deep muscle compartment; for the superficial compartment, angles are significantly increased for neutral position compared to plantarflexion and resting position. Pennation angles were also significantly different between superficial and deep compartment. The results of constant muscle volumes across the 3 ankle joint angles indicate the suitability of the method for capturing 3D muscle geometry. Absolute pennation angles in our study were slightly lower than recent literature. Decreased pennation angles during plantarflexion are consistent with previous studies. The presented method demonstrates the possibility of determining 3D fascicle orientations of the TA muscle in vivo.

AbstractThe Galileo high accuracy service (HAS) is a new capability of the European global navigation satellite system, currently providing satellite orbit and clock corrections and dispersive effects such as satellite instrumental biases for code and phase. In its full capability, Galileo HAS will also correct the ionospheric delay on a continental scale (initially over Europe). We analyze a real-time ionospheric correction system based on the fast precise point positioning (F-PPP), and its potential application to the Galileo HAS. The F-PPP ionospheric model is assessed through a 281-day campaign, confirming previously reported results, where the proof of concept was introduced. We introduce a novel real-time test that directly links the instantaneous position error with the error of the ionospheric corrections, a key point for a HAS. The test involved 15 GNSS receivers in Europe acting as user receivers at various latitudes, with distances to the nearest reference receivers ranging from tens to four hundred kilometers. In the position domain, the test results show that the 95th percentile of the instantaneous position error depends on the user-receiver distance, as expected, ranging in the horizontal and vertical components from 10 to 30 cm and from 20 to 50 cm, respectively. These figures not only meet Galileo HAS requirements but outperform them by achieving instantaneous positioning. Additionally, it is shown that formal errors of the ionospheric corrections, which are also transmitted, are typically at the decimeter level (1 sigma), protecting users against erroneous position by weighting its measurements in the navigation filter.

AbstractPurpose: The Prone positioning in addition to non invasive respiratory support is commonly used in patients with acute respiratory failure. The aim of this study was to assess the accuracy of an impedance-based non-invasive respiratory volume monitor (RVM) in supine and in prone position. Methods: In sedated, paralyzed and mechanically ventilated patients in volume-controlled mode with acute respiratory distress syndrome scheduled for prone positioning it was measured and compared non-invasively tidal volume and respiratory rate provided by the RVM in supine and, subsequently, in prone position, by maintaining unchanged the ventilatory setting. Results: Forty patients were enrolled. No significant difference was found between measurements in supine and in prone position either for tidal volume (p = 0.795; p = 0.302) nor for respiratory rate (p = 0.181; p = 0.604). Comparing supine vs. prone position, the bias and limits of agreements for respiratory rate were 0.12 bpm (-1.4 to 1.6) and 20 mL (-80 to 120) for tidal volume. Conclusions: The RVM is accurate in assessing tidal volume and respiratory rate in prone compared to supine position. Therefore, the RVM could be applied in non-intubated patients with acute respiratory failure receiving prone positioning to monitor respiratory function.

Published: March 2024

AbstractFutbol Club Barcelona operates the largest stadium in Europe (with a seating capacity of almost one hundred thousand people) and manages recurring sports events. These are influenced by multiple conditions (time and day of the week, weather, adversary) and affect city dynamics—e.g., peak demand for related services like public transport and stores. We study fine grain audience entrances at the stadium segregated by visitor type and gate to gain insights and predict the arrival behavior of future games, with a direct impact on the organizational performance and productivity of the business. We can forecast the timeline of arrivals at gate level 72 h prior to kickoff, facilitating operational and organizational decision-making by anticipating potential agglomerations and audience behavior. Furthermore, we can identify patterns for different types of visitors and understand how relevant factors affect them. These findings directly impact commercial and business interests and can alter operational logistics, venue management, and safety.
Structure discovery in PAC-learning by random projections
Authors: Kabán Ata , Reeve Henry 
Published: March 2024

AbstractHigh dimensional learning is data-hungry in general; however, many natural data sources and real-world learning problems posses some hidden low-complexity structure that permit effective learning from relatively small sample sizes. We are interested in the general question of how to discover and exploit such hidden benign traits when problem-specific prior knowledge is insufficient. In this work, we address this question through random projection’s ability to expose structure. We study both compressive learning and high dimensional learning from this angle by introducing the notions of compressive distortion and compressive complexity. We give user-friendly PAC bounds in the agnostic setting that are formulated in terms of these quantities, and we show that our bounds can be tight when these quantities are small. We then instantiate these quantities in several examples of particular learning problems, demonstrating their ability to discover interpretable structural characteristics that make high dimensional instances of these problems solvable to good approximation in a random linear subspace. In the examples considered, these turn out to resemble some familiar benign traits such as the margin, the margin distribution, the intrinsic dimension, the spectral decay of the data covariance, or the norms of parameters—while our general notions of compressive distortion and compressive complexity serve to unify these, and may be used to discover benign structural traits for other PAC-learnable problems.
