Advancing Healthcare Networks: Optimizing Multi-Objective RPL for Diverse Traffic in Low-Power, Lossy Environments
Authors: Animesh Giri
Published: May 2024

RPL: Powering modern healthcare IoT Networks. The Routing Protocol for Low Power and Lossy Networks(RPL) is a protocol specifically designed for routing in networks characterized by low power and lossy connections built on IPv6. It is specifically designed for the growing use of Instantaneous IoT (Internet of Things) applications. These networks cater to the specialized requirements of Low Power (resource-constrained) and Lossy Networks(unstable networks), also known as LLNs, where routing data smoothly and prioritizing traffic types are the significant challenges. Studies have shown that standard RPL, which makes use of a set of routing rules, struggles to provide the level of performance that many IoT applications in modern-day healthcare demand. This limits RPL’s potential in scenarios where we have a mix of data traffic, which is very common in healthcare settings. To handle the diverse data traffic found in healthcare settings, our method involves distributing several instances of RPL settings throughout the network. The main objective of this strategy is to improve the effectiveness of important and critical healthcare applications.
We have developed and thoroughly tested our system using Contiki, which is an open-source IoT operating system. We have three instances in our MultiInstance RPL setup, each of which is intended to handle different kinds of network traffic and provide varying Quality of Service (QoS) measures. Different sets of Objective Function (OF) rules are used by each instance to decide which route is optimal for the data it processes. We have made use of OF0 (Objective Function 0) and MRHOF (Minimum Rank with Hysteresis Objective Function). We have rigorously tested our solution. Our focus has been on metrics like delay, average energy consumption and Packet Delivery Ratio (PDR). Compared to standard RPL, our approach improved packet delivery rates and significantly reduced delays for high priority data packets. This research shows how to better address the complex data traffic needs of real-time healthcare IoT networks.

A problemática do ser, do não-ser e do devir no Sofista e no Timeu de Platão
Authors: Alves Thiago Staibano
Published: May 2024

Este artigo realiza um estudo de como a problemática do Ser, o Não-ser e o devir foi abordada na obra Platônica (especificadamente no Sofista e no Timeu), e em como a herança de pensadores como Heráclito e Parmênides se fizeram sentir nos rumos e soluções que Platão deu a esta questão. Conclui-se que há uma certa tentativa de harmonização, ora dando razão a teoria do devir de Heráclito e ora dando-se razão à teoria da impossibilidade do Não-ser (mesmo que reinterpretada) e da imobilidade do Ser de Parmênides. Por fim, percebe-se que no Timeu houve a necessidade da apresentação explícita de dois mundos para que o Ser, o Não-Ser e o devir pudessem coexistir, enquanto que no Sofista a separação do mundo não é citada como condição à existência destas categorias em um único e mesmo campo da realidade.

Authors: Halasi Nóra , Nábrádi András
Published: May 2024

A magyar fogyasztóknak nagyon erős a nemzeti öntudatuk, amely hatással van termékválasztásaikra is, valamint árérzékenységük mellett legtöbbször érzelmi alapon döntenek. Az etnocentrikus fogyasztók a külföldről származó termékek vásárlását nem tartják helyesnek, mert véleményük szerint ez negatívan hat a hazai gazdaság teljesítményére és növeli a munkanélküliség mértékét. A tanulmány az Észak-alföldi régió lakosainak hagyományos és tájjellegű élelmiszerekkel kapcsolatos ismereteit és fogyasztói szokásait vizsgálja. A kutatás eredményei alapján a termékek magyarságához leginkább a női fogyasztók ragaszkodnak, illetve azok a lakosok, akiknek a családjukban jellemzően az egy főre jutó jövedelem összege 51–75 ezer Ft. A termékek hagyományos jellege iránt azok a fogyasztók a legkevésbé elkötelezettek, akik maximum nyolc általános iskolai végzettséggel rendelkeznek. Az eredmények alapján azok a régióbeli lakosok tartanak ki kevésbé a hazafiasság mellett, akiknek a családjukban az egy főre jutó jövedelem összege 100 ezer Ft feletti, illetve felsőfokú végzettséggel rendelkeznek. A hazafiasság mértéke szignifikánsan a 18–29 éves korosztályban a legalacsonyabb. A hazafiassággal összefüggésben leginkább a 40–49 éves korosztály elkötelezett, továbbá a maximum nyolc általános iskolai végzettséggel, valamint szakmunkásképző vagy szakiskolai végzettséggel rendelkező fogyasztók körében magasabb szignifikánsan a hazafiasság mértéke.

Authors: Morales Vega Yamili , Rojas-Granados Adelina , Arellano-Rivera Esteban , Martínez-Díazaa Aurelia , Lescas Méndez Octavio , Angeles-Castellanos Manuel
Published: May 2024

Introduction: During childhood these sutures close, forming the characteristic sutures of the skull, one of these is the frontal suture, which joins the two frontal bones perfectly, simulating a single frontal bone. However, this suture can persist into adulthood, giving an anatomical variant known as metopism.

Case Report: A 19-year-old Mexican male presented with high-energy trauma related to a traffic accident while riding a motorcycle without wearing a safety helmet. A simple skull computed tomography (CT) was considered due to moderate risk factors for traumatic brain injury (TBI), based on the Master’s classification, progressive headache, presence of hematoma, facial injuries. When performing the simple skull tomography, persistence of the metopic suture was observed.

Conclusion: Metopism has generally been reported as a postmortem finding in population studies aimed at its search. This report has special attention because it was identified as a differential diagnosis of a skull fracture following a traumatic brain injury. The important finding that differentiates metopic suture from a fracture is the presence of serrated and sclerotic edges. A persistent metopic suture can be easily diagnosed by an anteriorposterior radiograph.
The Effect of Rational Drug Usage on Disease Adaptation and Quality of Life in Geriatric Patients with Cardiac Insufficiency
Authors: Akarsu Taner , Akgüllü Çağdaş
Published: May 2024

Aim: Due to chronic diseases that occur with advancing age, the number of medications used in geriatric individuals increases dramatically. This increment necessitates the rational use of drugs within a proper program. Reasonable drug use can affect individuals' adaptation to the diseases and their quality of life. This research was undertaken to explore the impact of rational drug use on disease adaptation and life Quality in geriatric patients with heart failure.
Materials and Method: The research involved a cohort of 322 individuals aged 65 and above. Participants completed a patient information form, including the Rational Drug Use Scale, the Chronic Disease Adjustment Scale, and the Elderly Quality of Life Scale (CASP-19). Statistical comparisons utilized t-tests, Mann-Whitney U tests, and ANOVA tests, while Pearson correlation analysis was employed to assess the associations between scale scores. Significance was determined for conditions with p-values less than 0.05.
Results: The study revealed a notable correlation between the patients' levels of rational drug use and their adaptation to the disease (r=0.226; p0.05). However, only in the group with polypharmacy was the total score of the physical adaptation sub-dimension of the ACIS significantly lower (p=0.011).
Conclusion and Suggestions: The research findings indicated that rational drug use among geriatric individuals positively influenced their ability to adapt to the disease, albeit resulting in a comparatively modest impact on the sub-dimensions of quality of life. Further studies are needed to evaluate rational drug use and to investigate its effect on symptom control, patient satisfaction, and quality of life in patients with heart failure.

Published: May 2024

Artificial Intelligence and its intersection with the law have garnered significant attention in recent literature. However, delving into what AI truly entails and its relevance to legal application and management is essential. This article aims to provide a comprehensive yet accessible overview of artificial intelligence (AI) and its legal implications. It strives to strike a balance between sophistication and clarity for non-technical readers. Initially, the discussion encompasses AI in a broader context before delving into its specific applications within the legal profession, for individuals and businesses navigating legal frameworks, and for government entities responsible for law enforcement. This distinguishes it from discussions that predominantly speculate on the future implications of AI in law. While such speculative dialogues have merit, it's crucial to acknowledge that they often rely on assumptions about the trajectory of technology, some of which may be unfounded. Amidst these futuristic discussions, the present-day legal and policy challenges posed by AI technology tend to be overshadowed.

Authors: Nehari Mohamed , Derhab Mohammed
Published: May 2024

This work is conserned with the construction of minimal and maximal solution for some equation quasilinear differentials with nonlocal boundary condition with nonlinearity is continuous function dependent on the first derivate in the time scale. In a previous study, see[11] it was found that there exists the extrimals solutions of a quasilinear elliptic system with intergral boundary conditions in the continuous case, and from here we asked the following question using the upper and lower solutions method coupled with monotone iterative technique and we asked the following question: do we have the existence of  extrimals solutions for certain classes of systems of differential equations with nonlocal boundary conditions in time scales by same method. We can classify the problem following the monotonicity of the two functions  and  in the true types.Type 1: Increasing qasimonotonic systems.Type 2: Decreasing qasimonotonic systems. Type 3: Mexed qasimonotonic systems. In this paper we show the existence minimuls-maximuls solutions if the problem is of the type 1. If the problem is of the type 2 , we show the existence of maximuls-minimuls solutions. If the problem is of the type 3 , we show existence of least quasilear-solution. In the end, we gave examples of the results presented in this work to prove their validity through two cases: the continuous case, represented by the set of real numbers, and the discontinuous case, represented by the set of integers.
Medium office energy consumption optimization using EnergyPlus
Authors: Liu Shu
Published: May 2024

This research paper studies the impacts of HVAC system scheduling and building envelope material properties on the building energy efficiency in the downtown New York City, metropolitan area, that is highly associated with Urban Heat Island. By utilizing EnergyPlus for whole energy building simulation, the research compares two HVAC operational cases: a baseline case with constant temperature setpoints, and an occupancy-based temperature setpoint schedule. The study also investigated the influence of thermal conductivity variations in stucco exterior wall materials, with three cases, the default baseline thermal conductivity and a 15% variance, respectively. Results indicate that occupancy-driven scheduling significantly reduces energy consumption by approximately 16% annually compared to baseline. Conversely, the influence of thermal conductivity on energy consumption is minimal, with only a 0.35% deviation noted in response to a 15% variation in thermal conductivity. This suggests that both optimizing HVAC scheduling and the thermal conductivity of building envelope materials can save building energy consumption while optimizing HVAC scheduling has a relatively stronger impact than optimizing the thermal conductivity with a 15% variance in downtown New York City.

Intelligent monitoring of surface evapotranspiration in the Heihe River Basin based on dual-source modelling
Authors: Pang Zijie , Su Kehao
Published: May 2024

[Objective] The Heihe River Basin, located in northwestern China, is the second largest inland basin in China, and its water resources play a crucial role in the ecology, agriculture and human life of the region. The aim of this study is to investigate the spatial and temporal variations of surface evapotranspiration in the Heihe River Basin and the potential impacts of these variations on water resource management. [Methods] To achieve this goal, we applied the PM-based dual-source model, a meteorological model for estimating global surface ET, which takes into account a variety of factors such as temperature, humidity, wind speed and downward solar shortwave radiation. By analysing the meteorological data and remote sensing data of the Black River Basin, we first investigated the spatial and temporal distribution of surface evapotranspiration. [Conclusion] The results show that surface evapotranspiration shows obvious seasonal and regional variations and is significantly affected by meteorological conditions. The inversion of surface ET in the Heihe River Basin by this dual-source model needs to be improved, and the trend of ET values calculated by the model is relatively small compared with the actual values.
Analysis of large-scale high-quality graphene production and applications
Authors: Li Sijia
Published: May 2024

Graphene, a single-atom-thick layer of carbon atoms arranged in a hexagonal lattice, is the thinnest and strongest material known to mankind. It has excellent electrical, thermal, and mechanical properties, making it a promising material for a wide range of applications in electronics, optoelectronics, energy storage, and more. With the increasing demand for graphene in various applications, large-scale and high-quality graphene production has become a significant challenge. While early methods of graphene production involved mechanical exfoliation, this method is limited in terms of scalability and yield. To meet the increasing demand for large-scale production of graphene, various methods have been developed in recent years, including chemical vapor precipitation, epitaxial crystal growth, graphene oxide reduction and solvent exfoliation and so on. This study aims to introduce several existing methods for the mass production of graphene with high quality and analyzes the advantages and disadvantage involve thereof. The findings in this paper may provide a valuable reference for the industrial-scale production of graphene.

Published: May 2024

Aqueous zinc-ion hybrid supercapacitors (ZISCs) known for their affordability, stability, and high energy density represent innovative energy storage devices. Porous carbon is usually used as the cathode material of ZISCs, and its structure significantly affects the dual performance of high power density and energy density of ZISCs. Herein, a one-pot carbonization strategy is proposed, eliminating the need for templates, additional heteroatom compounds, and activation processes. By precisely controlling the temperature to optimize the structure and electrochemical performance of carbon materials, we successfully synthesized hierarchical porous carbon materials (NOPC-800) with a high specific surface area of 1545.7 mg, featuring dual doping of 12.3 at% nitrogen and 13.35 at% oxygen. The self-doping of abundant nitrogen and oxygen atoms facilitates the chemical adsorption of ions and accelerates pseudocapacitive reaction kinetics. Leveraging these advantages, ZISCs were assembled using NOPC-800 as the positive electrode and zinc as the negative electrode, showcasing remarkable performance: a specific capacity of up to 121.9 mAh g, an energy density of 97.5 Wh kg, and a power density of up to 16000 W kg. Remarkably, NOPC-800 maintained an excellent capacity retention of 94.9% after 10,000 cycles at a current density of 10 A g. This research paves an innovative and feasible path for the design and advancement of novel heteroatom-rich carbon cathodes.

Published: May 2024

The study of particle deposition in ventilation ducts is crucial as it can have a significant impact on indoor air quality (IAQ) and human health. However, little research has been done on bends in ducts with different cross-sections. This study employs the Eulerian - Lagrange method to investigate particle deposition in a 90 elbow with gradually increasing and decreasing cross-sectional areas. The turbulence model used is based on the RNG k-, and the particulate phase is modelled by the discrete phase model (DPM). The study aims to discuss the effect of the cross-sectional asymptotic coefficient (K) and the Stokes number on particle deposition. The study found that as K increased, the particle deposition efficiency of the 90-degree bends decreased. Additionally, particles were primarily deposited on the outer curved surface of the bends. Specifically, when the particle size was 2 m, the pipe with K=0.75 had a particle deposition efficiency five times greater than that of K=1.25.

This publication presents a comparative analysis of the Local and Regional Government (LRG) sector workforce in five European countries: Croatia, Germany, Greece, Spain, and Sweden. Despite variations in governance models and industrial relations, commonalities emerge, such as the LRG sector's significance in the national public sector, a predominant female workforce, and strong organization within social dialogue and collective bargaining systems. Governance structures influence LRG workforce size, with Croatia and Greece displaying highly centralized administrations, while Spain, Sweden, and Germany showcase stronger LRG-level administrations. Notably, LRG workers constitute a substantial portion of public sector employment across all five countries. The gender pay gap is lower in the public sector than the private sector, declining over time. Diverging historical trends in LRG sector size are observed, with increases in Germany, Spain, and Sweden, while Greece experienced a decline linked to austerity measures. The study highlights variations in labour regimes. Training rights for LRG workers lack legal provisions in all countries except Spain, where it is included in collective bargaining. LRG workers benefit from a strong right to association, union representation, social dialogue traditions, and extensive collective bargaining coverage. Trade union presence is higher in the LRG sector compared to the private sector. Legal rights to strike exist for LRG workers in all countries except for German civil servants in the sector. While the ratification of the ILO Violence and Harassment Convention (No.190) is limited, all five countries have enacted national and EU legislation against workplace discrimination and harassment.

Исследовано поведение электрона в коллоидной нанопластинке CdSe, со-держащей примесные центры, при наличии аксиального магнитного поля. Вычисления проведены с учётом существенного скачка диэлектрической проницаемости в аксиальном направлении. Получено двумерное уравнение Шрё-дингера с эффективным потенциалом взаимодействия электрона с примесными центрами, локализованными в центральной плоскости нанопластинки. Показано, что с увеличением числа примесей, влияние магнитного поля на уровни энергии электрона ослабевает.

In the presence of the axial magnetic field, the behavior of the electron in the colloidal CdSe nanoplatelet containing multi-impurity centers has been investigated. The calculations have been carried out considering the essential jump of the dielectric constant in the axial direction. The two-dimensional Schrodinger equation with the effective potential of the interaction of electron and impurity centers, localized in the central plane of the nanoplatelet has been obtained. It has been shown that the magnetic field influence on the electron energy levels weakens with increasing the number of impurities.
Повышение разрешающей способности отображения рентгеновского фазового контраста в устройстве основанном на трехблочном лауэвском интерферометре

Рассматривается возможность повышения разрешающей способности отображения рентгеновского фазового контраста с использованием трехблоч-ного лауэвского интерферометра. Для устранения одного из недостатков указан-ной схемы – искажения интерференционной картины при дифракции предметной волны на анализаторе интерферометра – предлагается анализатор заменить двумя кристаллическими блоками равной толщины, которые являются дифрак-ционной линзой, подавляющей указанные искажения. Методом численного мо-делирования показано, что низкая когерентность исходного излучения повышает качество отображения фазового контраста предлагаемым методом.

The possibility of increasing the resolution of X-ray phase-contrast imaging on a device based on a triple Laue-case interferometer is considered. To address one of the drawbacks of this scheme – the distortion of the interference pattern during the diffraction of the object wave on the interferometer analyzer – it is proposed to replace the analyzer with two crystalline blocks of equal thickness. These blocks act as a diffraction lens, suppressing the mentioned distortions. Numerical simulations demonstrate that the low coherence of the initial radiation increases the quality of phase-contrast imaging using this method.

In this study, we have performed investigations on the structural stability, elec-tronic band structures, magnetic exchange couplings, and half-metallic performance of CrxCa1-xSe materials using computational methods of density functional theory via GGA-WC, GGA-PBE and, TB-mBJ exchange-correlation potentials. The CrxCa1–xSe compounds are thermodynamically stable and synthesizable owing to their negative formation energies. The structural parameters of CrxCa1–xSe with GGA-WC and GGA-PBE approximations appear to be in excellent concordance compared to the experi-mental data and recent theoretical calculations. According to GGA-PBE and TB-mBJ calculations, the CrxCa1–xSe compounds revealed integral magnetic moments and a half-metallic behavior with better half-metallic gaps, and spin-polarization of 100%. The CrxCa1–xSe alloys appear to be better materials for use in spintronic devices.
