Un diplomático en la guerra: las percepciones de Augusto de Vasconcelos en las legaciones portuguesas de Madrid y Londres y en la Conferencia de Paz, entre la neutralidad y la participación portuguesa en el conflicto (1914-1920)
Authors: Carvalho Soraia Milene
Published: July 2023

A presente análise centra-se nas leituras do ex-Ministro Plenipotenciário português, Augusto de Vasconcelos – Ministro português que se voltou para o republicanismo no final do século XIX, tornando-se posteriormente um forte apoiante da Liga das Nações, lutando pela Organização até ao seu fim na cena internacional no pós-Segunda Guerra Mundial -, e que nas Legações de Portugal em Madrid e Londres observou e teceu considerações sobre a participação do país no conflito nas diferentes ocasiões do seu aparecimento: na cena bélica desde 1916 e no momento anterior que dividia Portugal entre a neutralidade e a necessidade de assegurar a presença da República na Grande Guerra como oportunidade de participar nas negociações que se seguiriam na Conferência de Paz, ideia que não escapou às percepções de o Ministro.

Assim, com o objetivo de apresentar a noção de guerra do ponto de vista diplomático, pelos bastidores do conflito, destacamos o pensamento e a ação de uma das faces da diplomacia internacional do século XX: por meio da troca de correspondência. Entre legações e consulados, Portugal em Madrid, através de Augusto de Vasconcelos, configurou a sua presença na guerra com características de aproximação a Espanha, entendendo o conflito na linha dos portugueses, como um momento relevante para estreitar os laços multilaterais com vista ao para a conjuntura posterior, onde a América Latina, em sua opinião, teria um papel central.

Authors: عمر عبد الله عطا
Published: July 2023

يُعدُّ موضوع السُّنن الإلهية من أكثر الموضوعات التي اهتمَّ بها المعهد العالمي للفكر الإسلامي في مجلة الفكر الإسلامي المعاصر (إسلامية المعرفة سابقاً)؛ إذ ناقش هذه المسألة في أكثر من عدد، وتحت عناوين مختلفة، ومن زوايا متعددة، دراسةً ووصفاً وتحليلاً.
ولا غرابة في هذا إنْ علمنا أن موضوع السُّنن الإلهية هو من أكثر الموضوعات التي حفل بها القرآن الكريم، ووجّه إلى أهميته وضرورته القصوى في فهم حركة الوجود، وقوانين الكون، وطبائع الحياة، وسنن العمران، والتاريخ ومناهج الاستخلاف، وسُبُل التحضُّر، كما دلّت عليه هدايات الرسالة النبوية الخاتمة من خلال توجيهات الرسول r وأقواله وأفعاله وسائر أنشطته التي تصبُّ في إطار رسالة الوحي وتبيينها للأمة، وتقديم النموذج الحضاري الشمولي القدوة للرسالة الاستخلافية والوظيفة الشهودية، التي أنيطت بالإنسان المسلم وأُمّته التي وصفها القرآن الكريم بالخيرية والوسطية.

Authors: Souza Sérgio Domiciano Gomes de , Souza Anny Catarina Nobre de , Sousa Maria Losângela Martins de
Published: July 2023

A bacia hidrográfica é uma unidade territorial natural delimitada pelo relevo, configurando a rede de drenagem e sendo a principal fonte de recursos hídricos na Terra. Dada essa importância, o trabalho objetiva examinar como a bacia hidrográfica é colocada em relação ao planejamento e/ou gestão na literatura e nas leis ambientais do Brasil. Para tanto, realizou-se os seguintes procedimentos metodológicos: I. revisão integrativa da literatura na plataforma Gale primary sources com os descritores: “Bacia hidrográfica” AND unidade de planejamento; “Bacia hidrográfica” AND unidade de gestão, para o período de 2012 a 2022; revisão narrativa nos 28 trabalhos analisados; e II. coleta e consulta das principais leis ambientais do Brasil, cujos resultados estão apresentados e discutidos nas seções 1 e 2. Assim, vê-se que há uma disposição da literatura em estender a importância e contribuição da bacia hidrográfica para o planejamento e gestão dos recursos hídricos que ela produz, no sentido de integrar estes aos demais componentes da natureza de que fazem parte e possui relação sistêmica e dinâmica, para fins de gestão ambiental. Por outro lado, no campo das leis ambientais verifica-se que somente na Política Nacional de Recursos Hídricos, a bacia hidrográfica é adotada oficialmente como unidade de gestão dos recursos hídricos, entretanto do ponto de vista da gestão do território enfrenta-se desafios.

Authors: Mantilla Escobar Liliana Hilda , Murga Prieto María Judith , Huancas Donayre Ursula Idalina , Esteban Espinoza David
Published: July 2023

Sustainable development is a topic of particular interest in different nations around the world. In 2015, the United Nations designed the 2030 Agenda with 17 goals, including the eradication of poverty, combating climate change, and fostering sustainable cities and communities, among others. Therefore, it is essential to promote integration among various social actors, as well as public and private spheres, in order to consolidate these objectives. In line with this purpose, various educational institutions have adopted strategies that promote environmental awareness and understanding of sustainability among students. It is of interest to delve into the impact that volunteering activities have on strengthening environmental commitment among higher education students, considering the implications of these actions at both personal and professional levels. For this purpose, a survey was conducted among a sample of 63 students from the School of Global Business Administration at Ricardo Palma University in Peru. The survey aimed to explore the students' engagement with environmental causes and their perceptions of volunteering activities. The results suggest that these students are committed to environmental causes primarily due to their previous experiences. However, it is necessary to strengthen the connections established during volunteering programs beyond their completion, in order to promote the sustainability of these actions over time.
La funcionalidad de los elementos del arte folklórico y la mitificación del poder socio-cultural del indio en la narrativa de José María Arguedas
Authors: Príncipe Cotillo Guillermo
Published: July 2023

El objetivo del estudio consistió en analizar la función del arte folclórico -la música, el canto, la danza e instrumentos musicales- y el poder socio-cultural del indio en la producción narrativa de José María Arguedas. El enfoque -dentro del argot de tipificación de investigación que se viene utilizando- correspondió al análisis cualitativo de las fuentes de información. Para su desarrollo se utilizó los prepuestos teóricos de la metodológica hermenéutica literaria (Galván, l. 2008: 11), en sus niveles de análisis, interpretación y explicación crítica. Como resultado, se ha comprobado que la realidad andina es un contesto heterogéneo y contradictorio, personalizada por una alarmante desigualdad social entre dos fuerzas manifiestamente opuestas: la del patrón y la resistencia legendaria del indio. Los dos conviven en el mismo escenario, pero, marcados por una relación social antagónica: el patrón como dominante y el indio como dominado o subyugado. Frente a esta situación el indio posee como contrapartida una fortaleza tanto o más poderosa que la del patrón: su ancestral y milenaria cultura artística, encarnada en la práctica apasionada de la música, el canto, la danza, los instrumentos musicales, así como de sus ejecutantes que, impregnados de las fuerzas míticas de la naturaleza -los cerros,  las lagunas, los ríos, las aves, el cosmos u objetos simples, como el zumbayllu- se asocian metafóricamente en el poder, también mítico del indio, como para imponerse al patrón.

Siendo así, la función de la música o arte folklórico es pues rescatar, prospectivamente, el poder “escondido”, mítico que posee el indio no solo como para imponerse al patrón sino también acaso apostar por la ruptura de la barrera diferenciadora que los separa.
La educación biocéntrica, propuesta de una visión humanista
Authors: Llanos Zuloaga Martha
Published: July 2023

El presente ensayo representa un análisis crítico y reflexivo de los sistemas educativos antropocéntricos y la propuesta de una educación biocéntrica cuyo centro es la vida y en donde los seres humanos establecen interacciones significativas y horizontales con sus pares y con la naturaleza. El contexto actual con sistemas educativos condicionados por las economías y enmarques sociopolíticos de la economía neoliberal y en donde se prioriza la competitividad, limita el pensamiento crítico y el diálogo. Es necesario un repensar de la educación que ayude a las personas a aprender a vivir y convivir, como ya lo había señalado Delors, siendo el respeto a la vida y la convivencia armónica y afectiva con un enfoque reflexivo y vivencial en la práctica pedagógica, en que valoremos la integración de lo afectivo y lo intelectual. Proponemos una inteligencia afectiva y una percepción única de la sacralidad de la vida.

Convergencia incondicional en el sector manufacturero mexicano (1988-2018)
Authors:   , Rivadeneira Alex
Published: July 2023

In this paper, I document the existence of unconditional convergence in labor productivity across Mexican states in three-digit manufacturing industries. The rate of convergence for the period 1988-2018 is 1.18% per year. However, this result does not hold at the aggregate level: I find no unconditional convergence in manufacturing-wide labor productivity across states. Shift-sharing analysis reveals that the primary reason for this is the lack of labor reallocation towards more productive industries, and the underperformance of some of the largest ones. Unconditional convergence at all levels only occurred during 1988-1998. Afterward, the convergence process broke down and was only observed at disaggregated levels. I provide evidence that one possible cause of this breakdown is the socalled ''China shock". Additionally, I show that the convergence process, when it happened, has tended to exhibit a catching-down feature, where past-leaders have seen their labor productivity decline

A New Perspective: Electromagnetic Theory is the Fundamental Foundation for all Mechanical Principles of Newton's Laws
Authors: Das Nirod
Published: July 2023

The basic principles of Newton’s laws, and related concepts of momentum and energy and their conservation, are derived from the electromagnetic theory. The electric and magnetic fields produced by an electric charge in uniform motion, as derived from Maxwell’s equations, are used to find the forces the charge would exert on another charge, as measured in two inertial frames. These force transformation relations in the two frames are extended to apply to any general physical problem involving force. The force transformation relations are then used, together with the space-time relations of special relativity, to derive Newton’s laws of motion applicable for velocity much smaller than the speed of light c(v << c), as well as to derive general expressions for mass, momentum and energy, applicable for any velocity v≤c. Further, the momentum or energy as expressed in one inertial frame, are linearly related to the momentum and the energy expressed in another inertial frame. This result, when applied to a closed system with no external interaction, proves the momentum and the energy to be conserved, based on the required force-transformation relations. Fundamental and philosophical implications of the results and derivations are discussed. The basic principles of invariant electric and magnetic charge, upon which all electromagnetic concepts of Maxwell’s equations are founded, are recognized to be complete, general and the fundamental origin of Newton’s laws, making mechanical or material principles theoretically secondary.

Network slicing (NS) is becoming an essential element of service management and orchestration in communication networks, starting from mobile cellular networks and extending to a global initiative. NS can reshape the deployment and operation of traditional services, support the introduction of new ones, vastly advance how resource allocation performs in networks, and notably change the user experience. Most of these promises still need to reach the real world, but they have already demonstrated their capabilities in many experimental infrastructures. However, complexity, scale, and dynamism are pressuring for a Machine Learning (ML)-enabled NS approach in which autonomy and efficiency are critical features. This trend is relatively new but growing fast and attracting much attention. This article surveys Artificial Intelligence-enabled NS and its potential use in current and future infrastructures. We have covered state-of-the-art ML-enabled NS for all network segments and organized the literature according to the phases of the NS life cycle. We also discuss challenges and opportunities in research on this topic.
A single image based spectacle problem removal for improved ocular feature detection under spectacles
Authors: Mayaluri Zefree Lazarus , Gupta Supratim , Panda Nidhi , Thomas Nygel
Published: July 2023

Ocular image processing is an important step in applications like face recognition, driver fatigue detection, iris recognition, and gaze tracking etc. Secondary reflections and glare formed on the spectacles results in poor detection and localization of ocular features. Separating the reflection components accurately is a relevant and important challenge in enhancing eye feature quality under spectacles. Direct application of Dichromatic reflection model (DRM) based reflection removal algorithms on real-time facial images under spectacles—results in loss of ocular feature information in the diffuse component—as the DRM approaches fails to separate the chromatic and achromatic part of diffuse reflection. In this manuscript, we solve the problem of hue-saturation ambiguity by extending the DRM to Hue-Saturation-Value (HSV) colour space, and propose a new single image-based spectacle problem removal approach. Experiments on three set of databases demonstrate that the proposed approach achieves better solution with minimum execution time compared to the state-of-the-art.

Low Complexity Digital Quadrature Oscillators for Variable Frequency Applications
Authors: Sengupta Arkadeb , shahu vihan , Kundu Utsab , John Vinod
Published: July 2023

Switching frequency is utilized as a degree of freedom in digital control strategies for power converters. In addition to carrier-based schemes, quadrature oscillators offer an alternative method for the generation of variable frequency switching pulses. In this paper, amplitude instability in a computationally simple digital quadrature oscillator is analyzed. Algorithms for stabilizing the oscillator are developed based on this. Further implementation issues arising are addressed and a systematic comparison to carrier-based schemes is executed. It is shown that the proposed approach can be implemented with only 4 additions and 4 comparison steps without resorting to multiplication. The studies are validated in system simulation and experiments on a commercial FPGA board.

Published: July 2023

In this study, an EEG-based investigation of different levels of executive function activation (e.g., inhibition and working memory) during walking is performed in order to understand the executive funcions specifically involved during walking. Subjects were asked to perform the cognitive tasks by holding a wireless controller with their right hand. The wireless controller was chosen over the voice response to minimise muscle artefacts. The experimental protocol was composed by two part. In the first part, the subjects were required to execute the cognitive tasks by sitting on a chair; in the second part, the tasks were executed during walking. EEG data were collected with the wireless device ab medica Helmate composed by 10 dry electrodes positioned according to the international notation 10-20: AFz (ref), Fpz (ground), Fp1, Fp2, Fz, Cz, O1, O2, C5, and Cz. Quantitative gait assessment was performed with a 3D optoelectronic system consisting of eight Smart-D cameras at frequency of 100 Hz (BTS Bioengineering, Milan, Italy), for the calculation of spatial-temporal and kinematic parameters. 3D- stereophotogrammetric analysis was conducted using Helen Hayes M.M. markers set protocol, including 22 markers placed on the following body landmarks: spinous processes of C7 and S2, acromioclavicular joint, anterior superior iliac spine, greater trochanter, medial and lateral epicondylus femoris, fibular head, medial and lateral malleoli, I metatarsal heads and heel bilaterally.
Using ChatGPT to Annotate a Dataset: A Case Study in Intelligent Tutoring Systems
Authors: Vujinović Aleksandar , Luburić Nikola , Slivka Jelena , Kovačević Aleksandar
Published: July 2023

 Large language models like ChatGPT can learn in-context (ICL) from examples. Studies showed that, due to ICL, ChatGPT achieves impressive performance in various natural language processing tasks. However, to the best of our knowledge, this is the first study that assesses ChatGPT’s effectiveness in annotating a dataset for training instructor models in intelligent tutoring systems (ITSs). The task of an ITS’s instructor model is to mimic the human instructor by providing an effective tutoring action for a given student’s state. The instructor models are typically implemented as hardcoded rules, limiting their ability to personalize instruction. This problem could be mitigated by utilizing machine learning (ML). However, training supervised ML models requires a large dataset of student states annotated by corresponding tutoring actions. Using human experts to annotate such datasets is expensive, time-consuming, and requires pedagogical expertise. Thus, this study explores ChatGPT’s potential to act as a pedagogy expert annotator. Using prompt engineering, we created a list of actions a tutor could recommend to a student. We manually filtered this list and instructed ChatGPT to select the appropriate action from the list for the given student’s state. We manually analyzed ChatGPT’s responses that could be considered incorrect labels. Our results indicate that using ChatGPT as an annotator is an effective alternative to human experts. The contributions of our work are (1) a novel dataset annotation methodology for the ITS context, (2) a publicly available dataset of student states annotated with tutoring advice, and (3) a list of possible pedagogical actions.

This project aims to showcase a comprehensive set of models for predicting stock prices, including time series, econometric, statistical, and machine learning-based approaches. The dataset includes ten industry leaders from different sectors and NIFTY50, spanning from January 2017 to December 2022.

The models' performance was evaluated to determine which approach performs best for different sectors. The time series models employed include Holt's Linear Trend and Holt-Winters Exponential Smoothing, while the econometric model utilized is ARIMA. Additionally, the statistical model adopted is OLS, while several machine learning and deep learning models incorporated a range of techniques such as Random Forest, KNN, CNN, LSTM, etc. Besides predicting stock prices, the models were also designed to determine the direction of stock price movements. This project aims to provide insights into the best methods for predicting stock prices and direction across different industries by combining different models and approaches.
AmBC Symbiotic Intelligent Transportation Systems Covertness Performance Analysis and Optimization

Published: July 2023

With the continuous integration of wireless communication and intelligent information Technologies, the Internet of Vehicles (IoV) technology has been widely used in Intelligent Transportation Systems (ITS), which has greatly promoted the development of society in the direction of intelligence and information technology. Unfortunately, it is still facing the challenges of spectrum scarcity, ultra-low latency, large-scale connectivity and secure transmission. To this end, we study the covertness performance of multi-antenna assisted ambient backscatter communication (AmBC) Symbiotic ITS. To improve energy efficiency and reduce interference, the optimal antenna of the radio frequency (RF) source is selected to send covert information to covert receiving vehicle via both direct and reflected links with the help of public vehicle, while a monitor vehicle nearby the RF source covertly detects the potential communication behavior between the RF source and covert receiving vehicle. In addition, the RF source transmits a random power signals to interfere with the monitor vehicle’s detection. Specifically, the analytical expressions for the optimal detection threshold and the detection error probability (DEP) of the monitor vehicle are first derived, and then, the closed-form solutions for the outage probability (OP) of the covert receiving vehicle and public vehicle are computed. Then, an optimization scheme based on the maximize effective covert rate (ECR) under covertness and reliability constraints is proposed. Furthermore, the progressivity of OP at high signal-to-noise ratio (SNR) is investigated. The simulation results verify the analysis and prove that: i) the monitor vehicle’s detection performance can be reduced by lowering the power allocated to covert receiving vehicle within a certain range; ii) the OP of covert receiving vehicle is enhanced with the number of antennas; iii) as the RF source’s maximum transmit power increases, the ECR of the considered system increases and converges to a constant; iv) the multi-antenna selection scheme can significantly improve the covertness performance of the considered system.
Distributed UAV Swarm Augmented Wideband Spectrum Sensing Using Nyquist Folding Receiver
Authors: Jiang Kaili
Published: July 2023

Distributed unmanned aerial vehicle (UAV) swarms are formed by multiple UAVs with increased portability, higher levels of sensing capabilities, and more powerful autonomy. These features make them attractive for many recent applications, potentially increasing the shortage of spectrum resources. In this paper, wideband spectrum sensing augmented technology is discussed for distributed UAV swarms to improve the utilization of spectrum. However, the sub-Nyquist sampling applied in existing schemes has high hardware complexity, power consumption, and low recovery efficiency for non-strictly sparse conditions. Thus, the Nyquist folding receiver (NYFR) is considered for the distributed UAV swarms, which can theoretically achieve full-band spectrum detection and reception using a single analog-to-digital converter (ADC) at low speed for all circuit components. There is a focus on the sensing model of two multichannel scenarios for the distributed UAV swarms, one with a complete functional receiver for the UAV swarm with RIS, and another with a decentralized UAV swarm equipped with a complete functional receiver for each UAV element. The key issue is to consider whether the application of RIS technology will bring advantages to spectrum sensing and the data fusion problem of decentralized UAV swarms based on the NYFR architecture. Therefore, the property for multiple pulse reconstruction is analyzed through the Gershgorin circle theorem, especially for very short pulses. Further, the block sparse recovery property is analyzed for wide bandwidth signals. The proposed technology can improve the processing capability for multiple signals and wide bandwidth signals while reducing interference from folded noise and subsampled harmonics. Experiment results show augmented spectrum sensing efficiency under non-strictly sparse conditions. 
Performance, analysis and design of microwave photonic spectral domain filters using optical microcombs
Authors: Moss David
Published: July 2023

Microwave transversal filters, which are implemented based on the transversal filter structure in digital signal processing, offer a high reconfigurability for achieving a variety of signal processing functions without changing hardware. When implemented using microwave photonic (MWP) technologies, also known as MWP transversal filters, they provide competitive advantages over their electrical counterparts, such as low loss, large operation bandwidth, and strong immunity to electromagnetic interference. Recent advances in high-performance optical microcombs provide compact and powerful multi-wavelength sources for MWP transversal filters that require a larger number of wavelength channels to achieve high performance, allowing for the demonstration of a diverse range of filter functions with improved performance and new features. Here, we present a comprehensive performance analysis for microcomb-based MWP spectral filters based on the transversal filter approach. First, we investigate the theoretical limitations in the filter spectral response induced by finite tap numbers. Next, we analyze the distortions in the filter spectral response resulting from experimental error sources. Finally, we assess the influence of input signal’s bandwidth on the filtering errors. These results provide a valuable guide for the design and optimization of microcomb-based MWP transversal filters for a variety of applications.

Taxel-based Tactile Pattern Super Resolution
Authors: Wu Bing , Liu Qian
Published: July 2023

The past decade has witnessed the development of tactile sensors, which have been increasingly considered as an essential equipment in robotics, especially the dexterous manipulation and collaborative human-robot interactions. There are two major types of tactile sensors, i.e., the vision-based and taxel-based sensors. The latter is capable of achieving lower integration complexity with existing robotic systems, but unable to provide high-resolution (HR) tactile information as that of the vision-based counterpart due to the manufacturing limitations. Therefore, we propose a novel tactile pattern super-resolution (SR) scheme for taxel-based sensors, which is a generic scheme enabling customized selection on the number of applied "tapping" actions to achieve improvable performance from single tapping SR (STSR) to the multi-tapping SR (MTSR). In addition, we develop a new dataset for the proposed tactile SR scheme. In order to obtain scalable resolutions (e.g. $\times$4, $\times$10, $\times$20, etc.) of ground-truth HR tactile patterns, we propose a novel tactile point spread function (PSF) scheme to generate HR tactile patterns by leveraging the low-resolution (LR) data gathered directly from the taxel-based sensor and the depth information of contact surfaces. This is in strong contrast to the conventional ground-truth generation approach with overlapped multi-sampling and registration strategy, which can only provide a fixed resolution. Experimental results confirm the efficiency of the proposed scheme.

Published: July 2023

In this work, a holistic energy management methodology comprising forecasting and scheduling algorithms was developed. The algorithms aim at maximizing the customer benefits during normal operation as well as supplying critical infrastructure during grid events. Four separate real-world trials were conducted over a period of three months in the context of a demonstration in an MV customer with results showing that energy costs may be reduced to up to 27.3% while also dropping the system’s peak load demand by up to 16.7%. In terms of islanding capabilities, the trials demonstrate the system's ability to support the local network during blackouts and suggested the need for a formalization and standardization of the sizing process of any equipment with blackout capabilities within the planning of LV/MV systems. Additional use cases that aim at unveiling the flexibility offered to aggregators were examined and results showed that the proposed scheme can support flexibility services during Demand Response (DR) events.

Published: July 2023

This paper proposes the computation of three-level optimized pulse patterns (OPPs) that achieve not only load-friendly but also converter-friendly operation. To this end, the conduction and switching losses are modeled as a function of the OPP switching angles and the amplitude and phase of the converter current. By minimizing the current harmonics subject to an inequality constraint on the semiconductor losses, OPPs are derived that achieve minimal current distortions with a guaranteed upper bound on the semiconductor losses, thus ensuring the safe operation of the semiconductor switches within their thermal limits. Results for a neutral-point-clamped converter verify the benefits of this approach.

Advances in Artificial Intelligence play an important role in the development of modern Computer-Aided Diagnosis (CAD) systems. CAD software has greatly benefited from deep learning advances in disease detection. Nonetheless, these tasks remain challenging when it comes to the early stage of the disease where imaging atrophy is usually underrepresented in imaging data and annotated data are limited for efficient model training.  Indeed,  early disease diagnosis often requires discrimination between patients at the sub-category level, which is considered a fine-grained classification problem. The latter is a challenging task due to the subtle disease-specific patterns, clinically overlapping sub-categories (small variance), and hence the difficulty in learning medical clinically discriminant features. In this paper, we propose a  transformer-based framework that optimally learns a clinically meaningful disease representation for fine-grained classification of early Alzheimer's disease conditions using 18F FluoroDeoxyGlucose Positron Emission Tomography (18F-FDG PET) images.  The proposed method captures both local and global contextual clinical information from the whole image and learns a latent representation through a regularized objective function. The network training function is boosted using the Contrastive Learning (CL) paradigm. Yet, adversarial augmentation has been proposed for effective pairs mining for the optimization of the CL. The proposed method has been evaluated on six fine-grained classification tasks for AD detection and prediction on the ADNI dataset. Obtained results outperform recent  state-of-the-art approaches.
Feasibility of Battery-Powered Propulsion Systems for All-Electric Short-Haul Commuter Aircraft
Authors: Anker Markus Aasen , Hartmann Christian , Nøland Jonas Kristiansen
Published: July 2023

All-electric battery-powered aircraft have, over the last couple of years, had a clear path toward commercialization by the end of this decade. However, the development of smaller all-electric commuter aircraft has recently stagnated due to inherent technical limitations. To gain deeper insights into these challenges, this paper provides a detailed powertrain analysis of 9- and 19-seat all-electric commuter aircraft. Real-world mission profile data, obtained from 1500 flights in the Norwegian short-haul commuter network, are used as inputs. Regression analysis reveals that the cruising power needed is only about \SI{43}{\%} of the power needed for takeoff and climb. This work presents a comprehensive component-level weight distribution analysis of the all-electric powertrains investigated, and the required weight is shown to exceed the manufacturers' reported maximum takeoff weight (MTOW) of the two reference aircraft studied. However, small improvements in component performances could make electrification of the short-haul commuter network feasible, which is highlighted in a sensitivity study of the most critical electrical components. Additionally, our study highlights that the shortest missions are actually dimensioned by power rating rather than energy storage, adding an extra constraint on battery sizing for the shortest trips. 
Vysikaylo’ cumulative plasma cannon on the protection of the Earth from meteorites
Authors: Vysikaylo Philipp
Published: July 2023

 De Broglie reported that particles behave like waves. The author proves that de Broglie waves of free electrons in the plasma tail of a meteoroid behave like electromagnetic waves in a quantum resonator (laser) and form a beam (jet) of high-energy electrons directed into the meteoroid. A jet of high-energy electrons formed in the plasma tail behind the meteoroid sprays the meteoroid with the help of a Coulomb explosion (or a series of them).   Based on this idea, we proposed and investigated a new 4D inertial-polarization-quantum cumulative-dissipative Vysikaylo’s mechanism for the fragmentation of meteoroids and small comets (self-protection of the Earth from meteoroids) into simple ions and electrons.  
Acid rain and its environmental risks
Authors: الأسدي كفاح صالح
Published: July 2023

Acid rain is formed from the reaction of sulfur-containing gases, the most important of which is sulfur dioxide, in the presence of ultraviolet radiation.And the acidity of rain began to increase with the beginning of the industrial revolution, as a result of the huge emissions of sulfur oxides, nitrogen and carbon that are released into the atmosphere, as a result of burning fuels such as oil and coal.Acidic weather precipitation is not necessarily in the form of rain, snow, or fog. Acid compounds may arrive in dry form.

Published: July 2023

Introduction: A harmful pregnancy condition that harms both the mother and the fetus is perinatal asphyxia. It frequently happens as a result of challenges during labour, including protracted or challenging delivery, concerns with the umbilical cord, placental abnormalities, or maternal health conditions. Topiramate, an anticonvulsant, works through a variety of different methods. Topiramate looks to be effective as a neuroprotective agent as well as an anti-seizure medication in animal models of newborn brain injury. Angiogenesis, neurogenesis, and neuronal anti-apoptotic pathways are all stimulated and regulated by topiramate. In light of this, this observational study was conducted to ascertain Topiramate's negative consequences in kids with mild to moderate neonatal hypoxia. Methods: This observational case-control study was carried out in the Neonatal ward and ICU of Dhaka Shishu Hospital from April 2015 to March 2016. A total of 64 neonates were enrolled in this study and were assigned Group A -the interventional group (n=32) received topiramate and standard treatment protocol, and Group B or the control group (n=32) received only standard treatment protocol. The data were analyzed according to standard procedure. Results: Among the study neonates, based on sex in case and control groups, respectively, seventeen (17,53%) and twenty-one (21,66%) neonates were male, and fifteen (15,47%) and eleven (11,44%) neonates were female. Statistically, the sex distribution between groups was not significant (p=0.44). USG finding of the neonates after treatment was normal in 12 (48%) and 13(41%), and abnormal in 20(32%) and 19 (59%) neonates in the control and case groups, respectively. Out of 27 neonates in the control group, 11 (41%) were neurologically normal, and 16 (59%) had abnormal neurological findings. Out of 29 neonates in the case group, 24 (73%) were neurologically normal, and 5(17%) showed abnormal neurological findings. Statistically, significant variation ..
