Background/objectives

Adults with attention-deficit/hyperactivity disorder (ADHD) have more maladaptive cognitions, emotional problems and a poorer quality of life (QoL). A verification of the psychological model in clinical samples is needed for a better understanding of the mechanisms of ADHD diagnosis on QoL via maladaptive cognitions, emotional symptoms, and their interactions.

Methods

299 ADHD participants and 122 healthy controls were recruited. ADHD core symptoms, maladaptive cognitions, emotional symptoms and psychological QoL were rated. Pearson’s correlation and structural equation modeling were analyzed to explore the relationship and influence of ADHD diagnosis on QoL.

Results

More maladaptive cognitions, emotional symptoms, and poorer QoL were found in the ADHD group, and the dysfunctional attitudes were on par between ADHD with or without medication (p = 0.368). Moderate to strong correlations were found between emotional symptoms, maladaptive cognitions and QoL, and ADHD core symptoms presented correlations among the above scores (r = 0.157 ~ 0.416, p < 0.01) in ADHD participants. The influence of ADHD diagnosis on QoL was mediated through maladaptive cognitions, emotional symptoms, and their bidirectional interactions (p < 0.05), especially those with stable medication.

Conclusion

Our study is the first to verify the psychological model in adults with ADHD in China. The findings determined the direct influence of ADHD diagnosis on QoL and the indirect influence through maladaptive cognitions, emotional symptoms, and their interactions, emphasizing the importance of interventions for emotional symptoms and maladaptive cognitions for ADHD patients both with or without medication for a better QoL outcome.

Holiday heart syndrome: frequency and mechanism of development
Authors:   SBHI RR Kerch City Children's Hospital, Rybachok O. A.
Published: July 2023

Holiday heart syndrome is a heart rhythm disorder (usually atrial fibrillation) resulting from alcohol consumption by people who are generally healthy. As a rule, holiday heart syndrome is associated with binge alcohol consumption, while chronic alcoholism is characterized by a slightly different picture of cardiac disorders. The main symptom is palpitations - an irregular heartbeat that feels like skipped or extra heartbeats. Other symptoms are chest pain or pressure, shortness of breath, and fainting. Typically, symptoms resolve spontaneously within 24 hours. An irregular heartbeat can be serious. If the heart palpitations continue for more than a few hours, the patient should seek medical care. Some heart rhythm disorders (arrhythmias) associated with binge holiday heart syndrome can lead to sudden death, which may explain some of the sudden deaths commonly reported in alcoholics. Atrial fibrillation is the most frequent kind of arrhythmia in holiday heart syndrome.

The article presents a numerical study of the gas hydrate dissociation model in a reservoir under the action of microwave electromagnetic radiation at 400 MHz, 1 000 MHz, and 2 450 MHz. The decompo-sition of gas hydrate under this influence is faster at lower values of the reservoir’s initial hydrate saturation. The effects of 1 000 MHz and 2 450 MHz frequencies are much stronger than those of 400 MHz. The study shows that during heating times higher than 400 hours, 1 000 MHz frequency radiation electromagnetic heating is more efficient than that of 2 450 MHz frequency. Using the proposed mathematical model, it is possible to determine the optimal frequencies of the radiation source at a given time of heating the reservoir of a particular field. Moreover, the resulting calculation of energy efficiency (EROI ≥ 10) of this method for gas hydrate-extracted gas proves its competitiveness when compared to traditional methods of thermal impact on the reservoir.

Published: July 2023

The article presents a frame of a systematic approach to assessment, control, and formation of dynamic states based on the concept of level ties of elements of technical objects subjected to connected vibrational loadings. The methodological basis of the study comprises structural mathematical modeling that allows for a comparison of mechanical oscillatory systems, which are used as computational models for tech-nical objects, with structural schemes of automated operating systems that are equivalent to dynamic relations. A level interpretation of total generalized dynamic states is designed for mechanical oscillatory systems created with solid body with three degrees of freedom. Their significant features are reflected in the number of reso-nances, modes of oscillation amplitude setting to zero, and definite form of dynamic interactions. Based on the level ties, a system of general concepts is developed to depict the role of connection of vibrational loadings in creating border dynamic states of mechanical oscillatory systems. The results consist of analytical equations, graphical images, and numerical experiments.

Published: July 2023

During the COVID-19 pandemic, antenatal care (ANC) clinics monitored pregnant women for HIV testing as part of a surveillance program for the virus, especially in the lockdown period (2020–2021) worldwide. To guide community-wide HIV interventions and prevent mother-to-child transmission, studies on the demographics of expectant mothers who test positive for HIV can be used as proxies. During the COVID-19 epidemic, we planned to examine HIV testing among pregnant women receiving antenatal. Overall, no demographic factors were discovered to be significantly linked to HIV prevalence. However, studies on demographic traits, past HIV testing, and the COVID-19 pandemic found that young, less educated, primigravida, rural, and low socioeconomic level women comprised most of those who underwent tests. During the COVID-19 pandemic, there was a correlation between age, education level, employment position, parity, and HIV testing among pregnant women.

Published: July 2023

The high degree of uncertainty of market conditions, sanctions pressure and the high need for accelerated import substitution of high-tech products requires government authorities to develop solutions aimed at sustainable development of regions in the long term, taking into account national economic interests. It is impossible to ensure sustainable development without creating and regulating a system of state priorities. The consistency of the goals and actions of state governing bodies will allow us to enter a qualitatively new stage of development, preserving national identity. The key tasks facing the domestic economy during the transition to a new technological order are to increase the competitiveness of products, increase the share of high-tech goods and services in gross output, import substitution in all sectors of the economy. The national policy aimed at the implementation of the above-mentioned tasks requires large-scale investments in all areas of production, in increasing innovation activity and professionalism of personnel. For regions acting as independent economic entities, it is particularly relevant to build up innovation potential, attract investment in the process of capitalization of assets, growth of fixed capital, which become indicators of the attractiveness of the region for potential investors. The sustainable development of individual regions, taking into account their industry specifics, territorial features, the state of material, financial, production and human resources, requires detailed approaches to assessing the factors influencing the formation and use of innovative potential. Innovative potential becomes the foundation of sustainable development in conditions of high environmental volatility and a shortage of investment and financial resources caused by geopolitical crises and transformational processes in the global economy. The need to assess the innovative potential of the region as an economic system is due to the requirements of substantiating managerial decisions aimed at its socio-economic development. The result of investment activity is an increase in the economic and social indicators of the region, which is why it is important to comprehensively and comprehensively study the constituent elements of innovation potential, which will create prerequisites for sustainable development of not only regional, but also national policy. In the conditions of technological transition, innovative projects focused on environmental friendliness and reducing the negative impact on nature deserve special attention – green projects, the success of which requires control.

Published: July 2023

This chapter aims to deconstruct the conceptualisation and use of transformative assessment approaches for evaluating students in the post-COVID-19, digitalised learning era. Transformative assessment is underpinned by notions of multiple and inclusive ways of assessment, which are informed by the different learning approaches. To make a case for transformative assessment during this time of educational crises, the authors discussed the conceptual/theoretical basis of transformative assessment, transformative assessment strategies, the role of teachers in transformative assessment in the post-COVID-19 era, and the role of transformative assessment in teaching/learning in the post-COVID-19 era. The authors also explained the implications of COVID-19 for higher education teachers and made recommendations for further studies.

The financial stability of millions of older adults around the world rests on the shoulders of well-functioning pension systems. For this reason, the sustainability of such systems is one of the most important challenges facing states, especially in the face of low birth rates and increased life expectancy. Hence the growing importance of the debate over taxation and economic policy. This study presents the historical backgrounds of the pension system in Ecuador to give an all-encompassing view of its present configuration, and examines the relevant data of the factors that affect the pension system with the purpose of evaluating the sustainability of the Ecuadorian pension system in the long term. Both the historical and evaluative aspects of the study lead to an analysis of fiscal policies, the political relationships of the system and numerous exogenous processes that reveal aspects of the system that lack the expected solidarity.

Published: July 2023

In order to maximize range, a substantial portion of the interior volume of aircraft is allocated for fuel containment. To ensure the safety of aircrew and passengers, these systems must contain fuel and retain critical structural integrity in the event of a crash, self-seal and retain structural capability in the event of penetration, and suppress fire in the event of proximate ignition. Traditionally, light weight aircraft such as rotorcraft have accomplished these functions with heavy self-sealing bladder offset and isolated from primary structure. Boeing and the US Army Combat Capabilities Development Command Aviation & Missile Center's Aviation Development Directorate (ADD), together with the Joint Aircraft Survivability Program Office, have developed and demonstrated a structurally integrated fuel containment system that efficiently tolerates crash, self-seals, and suppresses fire at a lower weight and volume than traditional systems, thus maximizing space and weight capacity for fuel and payload.
An Alternative Forcing Function for Identifying Pilot Frequency Response Using a Series of Mesas
Authors:   San Jose State University Research Foundation, Bachelder Edward
Published: July 2023

The command inputs selected for system identification (SYSID) are dictated by numerous factors, some of which include: 1) The frequency range of interest; 2) The capability of the system to sustain the inputs; 3) The capability of the system to remain 'agnostic' to future inputs. When the elements comprising, the system being identified are all electro-mechanical, frequency sweeps, sum-of-sines, and impulsive inputs are standard identification techniques. However, when human manual control becomes an element of the system, the second and third factors are key considerations. Sum-of-sines (SOS) has been used extensively for identifying human control dynamics as it provides an input that is perceived by the pilot as random and focuses power at discrete frequencies. A disadvantage of SOS is the attentional demand it requires from the human operator, which limits the duration of an identification run to typically around one minute. This in turn constrains the lowest frequencies that can be identified, and multiple consecutive runs can lead to operator fatigue and performance degradation. Discrete inputs such as ramps have been employed with human-in-loop testing, but only with regard to Handling Qualities and performance testing. This work examines discrete inputs as a method for human-in-loop SYSID. An experiment was conducted using two terrain profiles: 1) Pop-up (POP), where four mesas (hills) of varying height, slope, and plateau length were unevenly spaced on flat terrain; 2) Sum-of-sines (SOS), where the terrain was comprised of the sum of eleven non-harmonically-related sine waves, so that the contour was perceived as varying randomly. The task for both terrain types was to maintain 20 feet above the ground using pitch (airspeed was fixed at 35 knots) for each run. Bedford workload ratings were collected after each run. Both terrain profiles produced approximately the same open-loop frequency responses, and their coherences were not significantly different. However, the Bedford ratings showed the POP profile was significantly easier to execute than SOS. The POP technique thus presents a less demanding, more appealing, and potentially more consistent way for eliciting frequency information relating to pilot gain, stability, and time delay.
Dynamic Stall modeling using Viscous Vortex Particle Method for Coaxial Rotors
Authors:   University of Michigan, Singh Puneet , Friedmann Peretz
Published: July 2023

Dynamic stall is an important source of vibrations on a rotor at high advance ratios. Dynamic stall loads are induced by periodic flow separation and reattachment. In this study, the flow separation is modeled as the shedding of concentrated vorticity, known as a vortex particle, from the leading edge of the airfoil. The rotor wake is obtained from the generation of vortex particles over the rotor blade using the Viscous Vortex Particle Method. Blade loads are calculated using a reduced order model obtained from CFD, and dynamic stall loads are calculated using the ONERA dynamic stall model. Results are presented for isolated and coaxial rotors at advance ratios of m = 0:3 and m = 0:4. The results indicate that the separated wake modifies the vibratory hub loads by 15%-30% for an isolated rotor at m = 0:3. The vibratory hub loads for the coaxial rotor are modified by 10%-65% at m = 0:4. The separated wake modifies the angle of attack distribution on the rotor and hence influences the loads. The upper and lower rotor tip path planes are tilted such that the blade and wake interaction increases on the retreating side of the upper rotor, and decreases on the advancing side.
H160 Dynamics Development: Setting New Standards
Authors:   Airbus Helicopters, Skladanek Yan , Hocquette Julien , Cranga Paul
Published: July 2023

In May 2015, Airbus Helicopters performed the first flight of H160 introducing its next generation of 6 ton helicopters. The dynamic behavior of the aircraft was set at a high priority from the beginning of this program. Comfort - including noise and vibrations- is for modern aircrafts not just a specification to which one seeks to comply with at the end of the development but a key driver of the design. The H160 development has been conducted in this manner and with the simple but challenging "guideline": setting new standards for vibrations at a minimum design cost. This paper reviews the challenges of this brand new helicopter development from the early design stage to the final in-flight assessment. With the successful flight testing of the pre-serial aircraft, the confirmed very low vibratory levels of H160 could be called to be as distinctive as its emblematic double swept Blue Edge™ blade.
Wind Tunnel Test on a Slowed Mach-Scaled Hingeless Rotor at High Advance Ratios
Authors:   University of Maryland, Wang Xing , Bauknecht Andre , Maurya Shashank , Chopra Inderjit
Published: July 2023

Slowing down the rotor in forward flight is a viable means of extending the cruise speed of a rotorcraft by alleviating compressibility effects at the advancing side blade tip. It was shown by previous wind tunnel tests that an articulated rotor trimmed to zero hub moment generates limited thrust at high advance ratios, because the advancing side of the rotor needs to be trimmed against the retreating side in the reverse flow state, where the rotor is ineffective in generating thrust. Therefore, a hingeless rotor that allows the advancing side to generate more thrust can be rewarding in overall thrust potential. At the University of Maryland, a rotor test stand was modified for hingeless rotors and two wind tunnel tests were conducted to investigate the behavior of hingeless rotors at high advance ratios. The experimental results, including performance and control, hub vibratory loads and blade structural loads, are presented in this paper and compared with predictions of the in-house comprehensive analysis, UMARC. The performance results demonstrate that a hingeless rotor with lift offset is capable in generating more thrust at high advance ratios, and the blade structural load results reveal that the predominant structural constraint on the rotor is in 2/rev flap bending moment, combined with 1/rev flap bending moment from the lift offset.
Research on Image Detection Algorithm of Rail Traffic Congestion
Degree Based on Convolutional Neural Networks
Authors: Lin Xin , Wu Shuang
Published: July 2023

With the sustainable development of the social economy and the continuous
maturity of science and technology, urban rail transit has developed rapidly. It
solved the problems of urban road load and people’s travel and brought about the
problem of rail transit passenger congestion. The image detection algorithm for
rail transit congestion is established based on the convolutional neural
networks (CNN) structure to realize intelligent video image monitoring. The CNN
structure is optimized through the backpropagation (BP) algorithm so that the
model can detect and analyze the riding environment through the monitoring
camera and extract the relevant motion characteristics of passengers from the
image. Furthermore, the crowding situation of the riding environment is analyzed
to warn the rail transit operators. In practical application, the detection
accuracy of the algorithm reached 91.73%, and the image processing speed met the
second-level processing. In the performance test, the proposed algorithm had the
lowest mean absolute error (MAE) and mean square error (MSE). In Part B, the MAE
and MSE values of the model were 16.3 and 24.9, respectively. The error values
were small, so the performance was excellent. The purpose of this study is to
reduce the possibility of abnormal crowd accidents at stations and provide new
ideas for intelligent management of rail transit.

Tras reconstruir cómo ha sido enmarcada desde su creación por el discurso de la memoria y de la JusticiaTransicional, toma distancia de este para explorar su impacto desde otro enfoque: el histórico-materialista. Para esto, parte de la tradición lukacsiana del análisis de la forma estética como algo que puede ofrecernos conciencia histórica, y de las ideas benjaminianas del tiempo histórico y del arte como técnica. Desde esta perspectiva, echa luz sobre dos dimensiones sociopolíticas hasta ahora poco estudiadas de la exposición. Por un lado, discute cómo esta construye una noción no-histórica de tiempo, en cuanto presenta un pasado desconectado del presente, y a la vez asocia los sectores sociales menos favorecidos con ese pasado. Por otro, explora cómo, en cuanto rescate archivístico y repertorio de fotografías, Yuyanapaq anima, aún 20 años después, a retrabajar sus imágenes para darles nuevos sentidos históricos.
Los trabajos de la memoria
Authors: Pajuelo Ramón
Published: July 2023

La reciente publicación de una nueva edición del libro de Elizabeth Jelin, Los trabajos de la memoria, es un acontecimiento editorial que no puede pasar desapercibido. Se trata de un libro que puede ser considerado un clásico del pensamiento social latinoamericano de las últimas décadas, y, al mismo tiempo, justamente por ello, es además un escrito abierto a la posibilidad de nuevas lecturas, preguntas e interpretaciones. Sin duda, gracias a la iniciativa del Fondo de Cultura Económica, es una buena noticia contar después de dos décadas de su aparición, con una edición pulcra que podemos considerar definitiva. Por eso cabe destacar, desde el inicio, que el libro sigue ofreciendo un modelo del ejercicio de la imaginación crítica rigurosa -aquella que enseñó ejemplarmente Wright Mills, y que tanto inspiró a la propia Jelin-, como vía para producir conocimiento acorde a la necesidad de renovados debates e interrogantes.

Stromal inflammation, fibrosis and cancer: An old intuition with promising potential
Authors: Oey Oliver , Sunjaya Angela Felicia , Khan Yasir , Redfern Andrew
Published: July 2023

It is now well established that the biology of cancer is influenced by not only malignant cells but also other components of the tumour microenvironment. Chronic inflammation and fibrosis have long been postulated to be involved in carcinogenesis. Chronic inflammation can promote tumorigenesis via growth factor/cytokine-mediated cellular proliferation, apoptotic resistance, immunosuppression; and free-radical-induced oxidative deoxyribonucleic acid damage. Fibrosis could cause a perturbation in the dynamics of the tumour microenvironment, potentially damaging the genome surveillance machinery of normal epithelial cells. In this review, we will provide an in-depth discussion of various diseases characterised by inflammation and fibrosis that have been associated with an increased risk of malignancy. In particular, we will present a comprehensive overview of the impact of alterations in stromal composition on tumorigenesis, induced as a consequence of inflammation and/or fibrosis. Strategies including the application of various therapeutic agents with stromal manipulation potential and targeted cancer screening for certain inflammatory diseases which can reduce the risk of cancer will also be discussed.

Exploring the dissemination of world-level intangible cultural heritage Guqin culture in Xiamen, Zhangquan
Authors: Yang HuiBing , Deng Guang , Lai Xueye , Li Xiang , Zhang Naijia
Published: July 2023

In recent years, the Chinese guqin culture has received more and more attention. And whether the target group of guqin culture dissemination is willing to carry out guqin culture dissemination is the result of a variety of factors, so this paper establishes a binary choice model and uses appropriate methods to filter variables to determine the base characteristics of the general group that is more willing to carry out guqin culture dissemination. The groups that are inclined to guqin cultural transmission among the general population have certain foundational characteristics. To this end, an in-depth investigation was conducted to examine the influencing factors that affect the dissemination of guqin culture among the general population. Based on the results of structural equation modeling, the model of influencing factors of Guqin culture dissemination is further fitted and practically used for potential groups of Guqin culture promotion.
A szervezeti kommuniáció fontosságának bizonyítása szervezeti diagnózisokkal
Authors: Ferenczné Szarvas Anikó
Published: July 2023

A szervezet strukturális és funkcionális jellemzői fontos meghatározói a kommunikációs lehetőségeknek, ugyanakkor a kommunikáció minősége jelentősen meghatározza a szervezet működésének jellemzőit. A szervezet kommunikációs hálójának diszfunkcionális működése feszültséget okoz, ami hosszú távon a szervezet  működésének egyéb tényezőiben is komoly problémákat okoz, ami nagymértékben csökkenti a hatékonyságot. Jelen tanulmány két szervezet szervezeti diagnózisának rövid bemutatásával próbálja bizonytani, hogy a szervezetek „tüneti” problémáinak hátterében a gyökérokok között elsődleges fontossága van a nem megfelelő kommunikációnak. A diagnózisokat a szerző készítette 2022-2023 között.

Tow Thomas Biquad Filter Based On State Variables Universal Design
Authors: bano Najbeen
Published: July 2023

Electrical engineers build a wide variety of systems that use filters, particularly analog filters. Indeed, even numerous computerized signal handling frameworks oftentimes incorporate at least one simple nonstop time channel, either inside or as a point of interaction with the simple continuous climate. In this examination, we center around state variable channels involving two Thomas Biquad channels in 180nm CMOS innovation. "State variable channels" treat the sign and its subsidiaries as factors. Although it requires numerous additional circuit components, this configuration provides the most precise implementation. There are simultaneous low-pass, high-pass, and band-pass outputs, and each of the three key parameters (gain, Q, and 0) can be changed separately. Keywords: Low Pass, High Pass, Gain Thomas Biquad filter

Several inequalities for an integral transform of positive operators in Hilbert spaces with applications
Authors: Dragomir S. S.
Published: July 2023

For a continuous and positive function \(w\left( \lambda \right) ,\) \(\lambda>0\) and \(\mu \) a positive measure on \((0,\infty )\) we consider the following Integral Transform \[ \begin{equation*} \mathcal{D}\left( w,\mu \right) \left( T\right) :=\int_{0}^{\infty }w\left(\lambda \right) \left( \lambda +T\right)^{-1}d\mu \left( \lambda \right) , \end{equation*} \] where the integral is assumed to exist for \(T\) a postive operator on a complex Hilbert space \(H\). We show among others that, if \( \beta \geq A \geq \alpha > 0, \, B > 0 \) with \( M \geq B-A \geq m > 0 \) for some constants \( \alpha,  \beta,  m,  M \), then \[ \begin{align*} 0 & \leq \frac{m^{2}}{M^{2}}\left[ \mathcal{D}\left( w,\mu \right) \left(\beta\right) - \mathcal{D}\left( w,\mu \right) \left(M+\beta\right) \right] \\ & \leq \frac{m^{2}}{M}\left[ \mathcal{D}\left( w,\mu \right) \left(\beta\right) - \mathcal{D}\left( w,\mu \right) \left(M+\beta\right) \right] \left( B-A\right)^{-1} \\ & \leq \mathcal{D}\left( w,\mu \right) \left(A\right) - \mathcal{D}\left(w,\mu\right) \left(B\right) \\ & \leq \frac{M^{2}}{m}\left[ \mathcal{D}\left( w,\mu \right) \left(\alpha\right) - \mathcal{D}\left( w,\mu \right) \left(m+\alpha\right) \right] \left(B-A\right)^{-1} \\ & \leq \frac{M^{2}}{m^{2}}\left[ \mathcal{D}\left( w,\mu \right) \left(\alpha\right) - \mathcal{D}\left( w,\mu \right) \left(m+\alpha\right) \right]. \end{align*} \] Some examples for operator monotone and operator convex functions as well as for integral transforms \(\mathcal{D}\left( \cdot ,\cdot \right) \) related to the exponential and logarithmic functions are also provided.
