Authors: Vukovic Miodrag , Stojkovic Goran , Zeljic Katarina
Published: October 2024

This study aimed to analyze the diagnostic and prognostic significance of miR-146a-5p in oral cancer and the association of the rs2910164 gene variant with miR-146a-5p expression. Thirty-five oral cancer patients participated in the study. Expression of miR-146a-5p in oral cancer, adjacent non-cancerous tissue, and the rs2910164 genotype variant were examined by real-time PCR. No difference was observed in miR-146a-5p expression between cancerous and non-cancerous tissues (P=0.272). It was concluded that miR-146a-5p is not a good diagnostic biomarker. There was no difference in miR- 146a-5p expression depending on the rs2910164 genotype. The rs2910164 variant was associated with tumor histological grade (P=0.037), stage (P=0.036), and lymph node status (P=0.025). There was a difference in survival between oral cancer patients with high and low miR-146a-5p expression (P=0.026), but not between patients with the GG and GC genotypes (P=0.400). Oral cancer patients with the wild-type GG genotype and high miR-146a-5p expression had significantly shorter survival when compared to patients with miR-146a-5p expression below the optimal cut-off and the wild-type genotype (P=0.035). A high miR-146a-5p level could be considered a potential biomarker of poor survival in patients with oral cancer, especially in those with the wild-type GG genotype of the rs2910164 variant.
Women Accountants and Wellbeing
Authors: Ghio Alessandro , Moulang Carly
Published: October 2024

SYNOPSIS

Women accountants continue to face numerous gendered barriers that challenge their ability to thrive. This study operationalizes a theoretical model grounded in conservation of resources theory to investigate the mechanisms through which women accountants’ psychological resources (wellbeing) are enhanced through informal organizational practices (role autonomy, psychological safety, supervisory support, organizational culture) and their relationship with organizational outcomes (engagement, burnout). Our survey findings highlight the crucial roles of supervisory support and psychological safety in boosting wellbeing. An organizational culture that fosters interpersonal trust also contributes positively. We emphasize the importance of wellbeing in reducing burnout and increasing engagement for women accountants. Our study identifies higher risk dimensions for women’s wellbeing, such as working in Big 4, having children, or being over 35. This research enhances our understanding of how psychological resources influence organizational outcomes, and stresses the significance of informal practices in supporting women accountants to thrive in a gendered profession.

Polarization maintaining fiber beam delivery for direct laser interference patterning
Authors: Froemel Paul , Baumann Robert , Lasagni Andrés Fabián , Eilzer Sebastian
Published: October 2024

Microstructured hollow-core fibers enable a flexible integration of high-power ultrafast lasers, offering the advantages of fiber-based beam delivery to ultrafast laser applications. For widespread industrial utilization of this technology, ever-increasing demands need to be fulfilled by adapting the beam delivery to new laser systems and process parameters. We demonstrate, for the first time ever, fiber-based beam delivery of high-power picosecond pulses with high polarization contrast in combination with direct laser interference patterning. By using an ultrashort pulse, high-power, near-infrared laser emitting a fundamental wavelength 1064 nm and pulse energy of 175 μJ at repetition rates up to 500 kHz, an interference pattern with a spatial period of 3.8 μm is produced and applied in stainless steel, illustrating the proof of principle. The fiber-based delivery system represents a versatile tool for 3D microtexturing processes using ultrashort pulse laser systems. The demonstrated results pave the way for high-quality microstructuring of large surface areas by employing fiber-based beam delivery systems.

Authors: Śmiarowska Joanna , Pawlik Natalia , Pisarska Joanna , Pisarski Wojciech A.
Published: October 2024

In this work, the oxyfluoride glass-ceramic materials containing LaF3 nanocrystals, prepared by using the sol-gel method, were described. The influence of fluoride nanocrystals on the photoluminescence properties of selected lanthanide ions was determined. The experimental results obtained for nano-glass-ceramics were compared to the precursor xerogels. Those Ln3+-doped sol-gel materials with dispersed LaF3 nanocrystals exhibit several visible emission bands. It was observed that heat-treatment process caused the elongation of the lifetimes of the 5D0 state from τ = 0.22 ms to τ1 = 0.79 ms, τ2 = 9.76 ms (for Eu3+-doped materials) and of the 4F9/2 state from τ = 0.027 ms to τ1 = 0.034 ms, τ2 = 1.731 ms (for Dy3+‑doped materials). The performed studies clearly revealed that luminescence behaviour also depends on an activator concentration and a distribution of energy levels of lanthanide ions.

Authors: Shopa Mykola , Ftomyn Nazar , Shopa Yaroslav
Published: October 2024

A dual-wavelength high-accuracy universal polarimeter was applied to the circular birefringence and optical activity measurement in potassium titanyl phosphate (KTP) nonlinear crystal. The experimental setup used two single-mode He-Ne lasers with close wavelengths of 594 and 633 nm as light sources. Measurement has been carried out for two crystal settings in directions of a 45-degree relative angle to the [100] and [010] crystallographic axes. Multiple light reflections inside the crystal sample were considered when processing the results of the polarimetric measurements. The results have been analysed using the optical transmission function for the polariser-sample-analyser system, and 2D intensity contour maps made it possible to determine the phase parameters, systematic errors, and eigenwaves ellipticity. It was found that the gyration tensor component of the KTP crystal is equal to g12 = 1.4 ⋅ 10−5 which in terms of optical rotatory power corresponds to the very small magnitude of the rotation value of 2.3 deg/mm.
Novel Insight into Inflammatory Pathways in Acute Pulmonary Embolism in Humans
Authors: Imiela Anna M. , Mikołajczyk Tomasz P. , Pruszczyk Piotr
Published: October 2024

Accumulating data have shown a pathophysiological association between inflammatory pathways and thrombosis. Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and acute pulmonary embolism (APE), is a significant health burden. It involves not only hemodynamic disturbances due to the emboli occluding the pulmonary arteries, but also platelet activation, endothelial dysfunction, and “firing up” of the inflammatory cascade. In humans, the systemic inflammatory state can also be evaluated using plasma levels of C-reactive protein (CRP) and interleukin (IL)-6, which correlate with venous obstruction, thrombus extension, and clinical VTE complications such as postthrombotic syndrome, recurrent thromboembolism, worse quality of life, and functional impairment. The exaggerated inflammatory state during postthrombotic syndrome aligns with severe alterations in endothelial function, such as activation of intercellular adhesion molecule (ICAM)-1 and E-selectin, as well as vascular proteolysis and fibrinolysis. Moreover, a hypercoagulable state, indicated by higher levels of von Willebrand factor (vWF) and factor VIII, is closely associated with the inflammatory response. We aimed to describe the role of basic inflammatory markers in daily clinical practice as well as the most important cytokines (IL-1β, IL-6, IL-8, tumor necrosis factor-a [TNF-α], growth differentiation factor-15 [GDF-15]). These markers could provide valuable insight into the interplay between thrombosis and inflammation, helping inform better management and treatment strategies.

Efficacy and safety of ACE inhibitors versus calcium channel blockers in the management of hypertension in adults: a systematic review
Authors: Bhutto Fahad , Alhazza Sultan , Alkadhi Badr , Alshehri Fahad , Alshehri Dhafer , Alghamdi Naif
Published: October 2024

Hypertension (HTN) is a prevalent cardiovascular condition managed with various antihypertensive agents, including angiotensin-converting enzyme (ACE) inhibitors and calcium channel blockers (CCBs). This study aimed to compare the effectiveness and safety of these two classes of medications in reducing blood pressure (BP) and achieving target BP. A comprehensive literature search was conducted evaluating ACE inhibitors (e.g., Enalapril, Captopril, and Lisinopril) and CCBs (e.g., Amlodipine, Diltiazem, and Nifedipine) for HTN management. The inclusion criteria were randomized controlled trials, observational studies, and comparative studies reporting on BP reduction, achievement of target BP, and adverse events. Data were extracted on study design, interventions, participant demographics, and outcomes. Study quality was assessed using the Cochrane Risk of Bias Tool and the Newcastle-Ottawa Scale. CCBs generally showed superior efficacy in BP reduction compared to ACE inhibitors. In terms of safety, ACE inhibitors were more frequently associated with cough and renal issues, while CCBs, particularly Amlodipine, were more prone to causing peripheral edema. CCBs, especially Amlodipine, generally offer greater BP reduction and a higher target achievement rate than ACE inhibitors. Despite the robust efficacy of ACE inhibitors like Enalapril, the overall safety profiles indicate that CCBs may provide a more effective approach for many patients. However, side effects such as peripheral edema need to be managed. This comparison underscores the need for individualized treatment strategies in HTN management, considering both the effectiveness and side effect profiles of antihypertensive medications.

From practical challenges to vocational training in small companies through knowledge pills
Authors:   University of Padua, BOLISANI Ettore , KASSANEH Tomas Cherkos , SCARSO Enrico
Published: October 2024

The paper focuses on vocational training of essential knowledge management (KM) practices for managers and employees of small and medium-sized KIBS (KnowledgeIntensive Business Services). For these companies, KM is critical, but employees need to be trained to implement KM practices effectively. Especially in small and medium-sized KIBS, there is a lack of resources and competence, and the implementation of KM is generally based on informal and unstructured methods. The paper illustrates the steps and the main outcomes of an EU Erasmus+-funded project aimed at implementing an elearning course targeted to KIBS. An international team, including Tallinn Technology University, Gdansk University of Technology, National University of Political Studies and Public Administration, University of Padova, Estonian Chamber of Commerce, and the Polish company 4Experience, carried out the project. The main outcome consists of a web-based platform where training content for KIBS professionals, managers, and employees was uploaded as “knowledge pills,” i.e., small batches of training content focusing each on a specific topic, issue, or practical problem. The development of the elearning platform is based on a sort of action-research approach. In fact, the course content and the training methodology approach were developed by implementing strict and continuous interactions between the research team and the companies. This modality proved effective because it effectively links the practical KM needs of companies with the KM experience of researchers.

Published: October 2024

This work is situated at the intersection between the knowmad and knowledge dynamics research domains, aiming to expand and develop the knowledge in the first segment of literature by drawing on the ideas and concepts of the latter. Furthermore, the paper focuses on the importance of reflection and enables the grounded theory principles as the execution framework of two-tailed qualitative research. The scholarly discourse around knowmads has usually focused on their talents, geographical context, and personality traits, as well as professional skills and competencies. However, there has been a lack of research conducted about knowmads from the knowledge dynamics perspective. The study employed qualitative research methods, including debates and interviews. The researcher enabled the grounded theory technique and prompted the participants to reflect on their decision-making process when becoming knowmads. In our investigation, we started by identifying as many intellectual, emotional, and spiritual factors as possible within a group debate, and we followed up with in-depth, one-on-one, semi-structured interviews. Upon interpretation and analysis of collated data, we successfully identified three prototypes of knowmads. The first portrait is of the pragmatic knowmad, driven by practical and materialistic considerations; the second one is instinctual, aware of their intuition and emotions, and led by a sixth sense. The third type, the ethical knowmad, is predominantly motivated by identifying their ideals in the reality of professional collaborations. By employing a qualitative research methodology focused on knowledge dynamics, we facilitated reflection processes and gave meaning to the experiences of eleven knowmads, developing state of the art in the field.

Using a quantitative approach featuring surveys and statistical analyses, it scrutinizes how employees perceive their immediate bosses' leadership and decision-making qualities and their potential links to transformational leadership. The key findings underscore statistically significant connections between socio-demographic variables and positive perceptions of transformational leadership, further reinforced by insights gained from real-life examples showcasing the successful application of transformational leadership within the Ministry. The study also illuminated the organizational impact of knowledge strategies, providing tangible evidence of enhanced performance through effectively applying these strategies. These findings emphasize the necessity for tailored leadership development programs, adaptability, and self-awareness among leaders to cater to a diverse workforce and the specific needs of various departments in alignment with the transformative principles of real-life examples. While not establishing causation, this research enriches our understanding of how transformational leadership is perceived within intricate organizations, shedding light on its multifaceted nature and capacity to drive organizational success, as exemplified by the practical illustrations from real-life cases.

Insufficient financial education initiatives, economic shortcomings, and limited expansion of the Romanian financial system create an endless loop of challenges: the Romanian economy does not benefit from the characteristics of an advanced financial system, and the financial system does not take full advantage of the growth and opportunities offered by the Romanian economy. Despite increasing income convergence, Romania has a shallow level of financial education. The research shows the main determinants of low financial literacy and the individual socio-economic characteristics that influence low levels of financial literacy. The results provide a solid framework for policy-making and private initiatives to increase financial literacy and well-being.

Numerical Analysis of Small Caliber Spinning Projectile with Variety Boattail Configurations
Authors: Khormi Hassan , Alfifi Salman
Published: October 2024

Range extension has received great interest in the field of artillery and spinning projectiles. Reducing base drag is an effective way for rang extension, because it is a major component in transonic and supersonic Mach numbers. Boattailing is considered as one of the most implemented techniques to reduce base drag. This work uses variety of passive drag reduction techniques over M33 .50cal projectile. Multiple design variations on projectile boattail are considered. This includes varying boattail angle, use of riblets, and use of arced boattail. Computations are conducted using computational fluid dynamics by solving RANS equations. Simulations are performed over Mach numbers from 0.6 to 2.5. The aim of the simulations is to calculate most affecting aerodynamic forces and moments which include drag force, lift force, Magnus force, Magnus moment, overturning moment, and spin damping moment. Then these coefficients are compared for all design variations. Results are validated by comparing with experimental and numerical results from the literature. Furthermore, a mesh independence study is done for verification. It was found that every configuration has good performance at a certain speed range with regard to zero yaw drag and significant yaw drag reduction for riblets boattail for low supersonic speeds.
Optimal Agile Satellite Target Scheduling with Learned Dynamics
Authors: Stephenson Mark A. , Schaub Hanspeter
Published: October 2024

Target sequencing is an important aspect of agile Earth-observing satellite scheduling. The objective of the problem is to find a feasible imaging sequence that maximizes the cumulative value of unique heterogeneously valued requests; no expendable resource constraints (power and data storage) are considered. Two challenges are encountered: transition times between targets are dictated by dynamics of an arbitrary controller, and the solution space is combinatorial with respect to request count. To find dynamically accurate time-dependent attitude maneuver transition times, a neural network is trained on simulated slew data; this allows for the generation of more physically accurate, and thus better performing, schedules than when using the traditional approach of lower-order models for slew feasibility. Next, slews between requests are represented by a sparsified graph, and a mixed-integer linear program is formulated to solve them; the sparse formulation keeps the problem tractable over longer planning horizons and larger numbers of requests when compared to the standard approach. The solutions are optimal up to the quality of the transition time estimator and a time discretization. Finally, the solutions are verified in a high-fidelity simulation, demonstrating validity when deployed on a lifelike system. Time-dependent request values and multiple satellites are also considered.
End-to-End Differentiable Model for Optimization of Rocket-Powered Vehicles Including Plume Radiant Emission
Authors: Mathesius Kelly J. , Sharpe Peter D. , Hansman R. John
Published: October 2024

This paper proposes an end-to-end differentiable model for infrared radiant emission for low-altitude exhaust plumes. Considering plume radiant emission during the design phase is important for ensuring vehicle design constraints and objectives can be met while accounting for the coupling of plume radiant emission with other aspects of vehicle design. The model is suitable for computational frameworks using automatic differentiation or gradient-based optimizers—such as CasADi and AeroSandbox—which enable direct optimization of solid rocket-powered vehicle design with constraints on plume radiant emission. It consists of six submodels of different coupled physical phenomena: chamber thermodynamic equilibrium, motor internal ballistics, isentropic nozzle flow, plume flow field, afterburning kinetics, and radiative transfer. The combined model shows reasonable agreement for several different rocket-powered vehicles. The use of the model is demonstrated in an example case study for optimizing a low-thrust, transonic, rocket-powered aircraft concept.
