Strategic human resource management in digital marketing and business: Birds eye from Indonesian enterprise
Authors: Soekiman Susanto
Published: June 2024

Human resources are considered an important resource for companies today because the knowledge that a person has can be used to become an organisation’s competitive advantage. In addition, digital marketing has an important role in determining the performance of business entities because we have now entered the digital era, which certainly cannot be separated from the influence of technology on marketing through social media. Therefore, this study aims to examine the effect of Strategic Human Resource Management (SHRM) in digital marketing on business entity performance, which is determined by digital marketing in a business entity. The data in this research was collected by distributing questionnaires to 455 Micro Small Medium Enterprises (MSMEs) in Indonesia. Data analysis used the Moderated Regression Analysis (MRA) method. The research results show that strategic human resource management variables influence business performance, and the support of digital marketing capabilities and activities strengthens this influence. Based on the results of this research, existing business entities must strengthen organizational performance by strengthening human resources in basic soft skills and hard skills and skills in digital marketing and improving marketing activities using digitalization.
Tobacco Consumption and Respiratory Consequences
Authors: Iorga Ana Luiza , Slabu Andreea-Dumitrita , Mihălţan Florin Dumitru
Published: June 2024

Tobacco is a substance used for recreational purposes that is frequently included as a risk factor with multiple implications in the pathophysiology of the main diseases with high mortality and morbidity. Smoking is a habit with increased prevalence at the population level and the burden given by it resides in the high latency time between the first exposure and the appearance of the first symptoms. This study aimed to quantify the effects of smoking and the impact of relatively short-term withdrawal on the main parameters that are measured in any pulmonology service.

Material and method. In the presented study, a group of 106 smokers was included, who applied their initiative to the STOP FUMAT program within the “Marius Nasta” Pneumology Institute Bucharest during 2022-2023.

Results. To study the impact of withdrawal in the relatively short term, the group that initially consisted entirely of smokers was divided after 6 months into group I - 41 smoking patients and group II - 54 weaned patients. A main characteristic of the group as a whole is represented by the main reason for quitting smoking represented by the ticking in the questionnaire by 93.4% of the concern about the impact on the health of smoking which correlates with the increased level of diagnosed respiratory pathologies (79.2% ) and comorbidities associated with smoking 28.3%. It was also demonstrated that although there was a slight tendency towards a reduction in FEV1 in patients from the smoking group at the 6-month assessment, it was still statistically significant among weaned patients.

Discussion. Tobacco use increases the risk of cardiovascular, respiratory, and neoplastic diseases, currently representing the main preventable risk factor for death.

Conclusion. Smoking remains a public health problem due to the multitude of long-term effects it has on health. The current study reinforces the consequences of tobacco consumption on patients and at the same time highlights the positive effects of withdrawal on the evolution of the case, which represents an additional argument for the repeated support and recommendation from the medical staff to go to STOP FUMAT centers.
The Impact on the Quality of Life of Patients with Drug-Resistant Tuberculosis – Brief Review
Authors: Butnaru Teodora , Mihălţan Florin Dumitru , Ancuţa Constantin
Published: June 2024

Drug-resistant tuberculosis (DR TB) is a major threat worldwide, despite the fact that the EndTB strategy involves early diagnosis and prompt treatment of all people of all ages with any form of sensitive or drug-resistant tubrculosis. Both forms of tuberculosis imply high morbidity and mortality, but drug-resistant TB accentuates these aspects due to problems arising from the nature of long and difficult to tolerate treatment, which can often lead to abandonment. The impact of tuberculosis is not limited only to clinical indicators, but also to the quality of life, directly reduced by the disease and treatment (weight loss, asthenia, medication side effects, distant sequelae, comorbidities), but also indirectly through the nature of the disease (social inclusion, job loss).

For this short review, the PubMed database was used, using key words such as quality of life, drug- resistant tuberculosis, physical, emotional impairment, treatment side effects. Patients with treatment-resistant tuberculosis face limitations in all areas of quality of life due to tuberculosis, both at initiation of treatment and at its completion. The impact of tuberculosis affects all areas of quality of life, both physically, emotionally, professionally and financially, both at initiation of treatment and post-treatment. The particular aspect of psychological impairment of DR-TB patients requires additional attention from the medical professionals involved in treating these patients and implementing additional support measures to help patients. The quality of life of patients with drug-resistant tuberculosis is an area that requires additional research, having an extremely important role in the success of antituberculosis treatment. Quality of life indicators could shape a more complete picture of TB’s impact on patients’ lives, both during and after treatment.
365 Days - Evolution and Rehabilitaton Strategy in a Uncemented Hip Replacement Prosthesis Case Study
Authors: Geambaşu Adina , Costache Raluca Maria , Constantin Ancuţa Alina
Published: June 2024

Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis.

A total hip replacement (total hip arthroplasty or THA) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is currently one of the most common orthopaedical operations, though patient satisfaction short- and long-term varies widely.

In this paper we present the case of a 75-year-old woman, with classic uncemented hip prosthesis intervention, from the preoperative preparation stage to 1 year after the intervention and the recovery phases and their evolution. Due to a quality management of the intervention and good hygiene and nutrition, the lack of osteoporosis and the absence of paleopathology, the patient recovered in a fast and correct manner, returning to a good functionality and state of health. Also, the cooperation between the patient, family, therapist, doctor and psychologist had a decisive role in the success of both the intervention and the postoperative period with optimal results for the age and possibilities of the patient.
Perspectives in Smoking Related Interstitial Lung Diseases
Authors: Constantin Ancuţa , Catrangiu Maria-Beatrice , Iorga Ana-Luiza
Published: June 2024

Interstitial lung disease is a generic term encompassing a wide range of unrelated conditions that have in common a tendency to cause shortness of breath and/or cough associated with bilateral abnormal opacity of various types on conventional chest X-rays or high-resolution computed tomography scans, symptoms including dyspnea, wheezing, cough, and/or sputum production. This study aimed to show that cigarette smoke is a powerful inducer of inflammation and the cause-effect relationship between cigarette smoking and interstitial diseases – respiratory bronchiolitis-associated interstitial lung disease (RB-ILD) and desquamative interstitial pneumonia (DIP). We bring to your attention the cases of two patients, heavy smokers with HRCT images suggestive for RB-ILD and DIP. The patients present to the on-call room with dry cough, exertional dyspnea and receive corticosteroid treatment with the recommendation to cease smoking. An approach would be to target high-risk populations, such as older adults with a history of smoking for early diagnosis of parenchymal lung diseases (e.g. ILD and chronic obstructive pulmonary disease) or lung cancer.
Wartanian glacial sediments: insights into deglaciation of Polish Lowlands and Highlands border for geotourism
Authors: Górska-Zabielska Maria , Wachecka-Kotkowska Lucyna
Published: June 2024

This paper presents five sites located in the marginal zone of the Wartanian stadial within the Odranian Glaciation (MIS6a) on the border of the Central Polish Uplands and Lowlands, representing different glacial forms and geological structures: terminal moraine hill, undulating moraine hill, sedimentary margin of the ice sheet, kame hill, and outwash plain. This differentiation is also reflected in the petrographic composition of the gravels and the interesting surface microstructures of the Scandinavian erratic boulders. This small study area, with its high geodiversity, which we have identified and investigated, has considerable potential for sustainable development. Geotourism is a tool for this development in a peripheral tourist region, providing both economic benefits for the local population and conservation services for the geoecosystem.
Influence of seasonal change and anthropogenic activities on the avifauna composition in a seasonal wetland of India
Authors: Debnath Rupam , Pal Sandip
Published: June 2024

Seasonal wetlands harbour a mosaic of habitats that support a variety of niches for bird species. When seasonal change and anthropogenic activities are coupled with the landscape, the species richness and species composition are presumably influenced by such factors. This study aimed to evaluate avifauna diversity, to investigate feeding guilds, and to determine the impact of seasonality and tourism pressure as anthropogenic disturbance on the avian community of a wetland. Comprehensive surveys were conducted to gather all necessary data, followed by the application of analytical methods to assess the hypotheses formulated in the current research. A total of 61 bird species belonging to 14 orders have been recorded during this year-round study, where Passeriformes was the most dominant order with 27 bird species. The species richness was highest in winter, and five feeding guilds were identified. This study revealed a significant role of seasonality, and tourism pressure on avian species richness of Bortir Bil. The outcomes of the present study could serve as an important baseline to adopt sustainable and bird-friendly management plan for this seasonal wetland.

Authors: Gyurácz József , Bánhidi Péter , Góczán József , Illés Péter , Kalmár Sándor , Koszorús Péter , Lukács Zoltán , Molnár Péter , Németh Csaba , Varga László
Published: June 2024

In this study, we detected and compared changes in the annual and daily captures of the Eurasian (Certhia familiaris) and Short-toed Treecreeper (C. brachydactyla) in the timing of their post-breeding movements, in the length of minimum stopover duration (MSD) in the area, and also in biometrics in western Hungary. The birds were captured and ringed, or recaptured from the end of July to the first weekend of November in all years from 2001 to 2023. The annual captures of both species indicated stable populations in this period, with milder February months having a positive effect on annual captures. There were similarities and differences in the movement strategies and habitat selection of the species. During the post-breeding season, the Eurasian Treecreeper was more strongly associated with the scrubland and forest edge than the Short-toed Treecreeper. There were two autumn capture waves in September and October for the Eurasian Treecreepers and just one in September for the Short-toed Treecreepers, which were primarily consisted of birds captured only once. There were no significant differences in wing length of the three capture intervals (July-August, September, October-November) in either species, which suggests that the dynamics of post-breeding movements cannot be explained on the bases of possible differences in the behavior of sexes, ages, or populations. The proportion of birds captured only once was about double of that of stopovers in both species each year. The average real length of stopover duration in the area for Eurasian Treecreepers was 94.25 days, and 84.31 days for Short-toed Treecreepers. The length of MSD in the area was not significantly associated with wing length and body mass in either species. Individuals of both species did not gain fat stores significantly during post-breeding season.

Authors: Molnár Márton , Gorman Gerard , Schmidt András
Published: June 2024

This paper summarizes a two-year (2021 and 2022) survey which sought to determine the breeding population of White-backed Woodpecker (Dendrocopos leucotos) in Hungary. The survey was initiated by the Hungarian Woodpecker Group of MME/BirdLife Hungary and was the first to be conducted nationwide on this species. All hill ranges where the species was historically known to occur were visited. A total of 31 observers were involved, and 102 UTM squares in which White-backed Woodpeckers were known to breed, or potentially breed, were visited. The results suggest that the Hungarian breeding population of this endangered species ranges between 480 and 800 pairs.
Additional data to the historical breeding of the Eurasian Woodcock in the Carpathian Basin
Authors: Bozó László , Bende Attila
Published: June 2024

The Eurasian Woodcock is a regular breeder in the wooded areas of the Carpathian Basin. In the past, several literature reviews on the distribution and breeding biology of the species in the Carpathian Basin have been published, but these have ignored the annual reports on spring returns collected between 1894 and 1926 under the coordination of the Hungarian Ornithological Centre. These included 379 nesting records from the present area of Austria, Croatia, Hungary, Romania, Serbia, Slovakia, Slovenia, and Ukraine. The majority of the data came from the Carpathians, with a smaller number from forested areas in the lower mountains and hills. It was particularly rare in lowland areas, with most of the records coming from floodplain forests. The spatial distribution of the data is somewhat at odds with that described in recent summary works. From the Northern Carpathians and the Eastern Alps, however, these sources report fewer nestings, and most of the data come from Transylvania. The temporal distribution of the data is consistent with previously published results. In some cases nestings were found in late February and early March. The peak of nesting was in April, with only a small number of nestings reported in the second half of May. Breeding occurred significantly later in areas at higher altitudes. Nevertheless, it can be concluded that knowledge of the species’ nesting in the Carpathian Basin is still incomplete.

Authors: Horváth Ida , Futó János , Eugen Kessler Jenő
Published: June 2024

We describe Phalacrocorax bakonyiensis n. sp. an extinct member of the cormorants (Phalacrocoracidae). The fossil was found in 2021 by geologist János Futó in the sediments of a small cave cavity on the side of Várhegy in Sümeg, a part of the Bakony Mountains of West Hungary, where Late Miocene (MN11–12) vertebrate fossils have been found in the past decades. The total number of bone fragments collected was 14, of which only three can be identified. Two of these belong to adults and one, due to its poor preservation and size, to a very young specimen.
Flow Simulation-Based Methodology for Reducing The Risk of Fuel Fire In An Aircraft’s Fuel System Enclosure
Authors: Sznajder Janusz
Published: June 2024

This study applies advanced computational fluid dynamics (CFD) simulations to enhance the safety of an aircraft’s fuel system by striving to minimize the risk of on-board fire hazards. Employing a detailed flow simulation model, this research assesses the efficacy of newly designed measures within a fuel system, designed for a modified radial engine on a test-bed AN 2 airplane. The model simulates internal airflow, droplet particle flow, the formation of Eulerian Wall Film, and the vaporization process from the fuel film within the enclosure of the aircraft’s equipment bay. By exploring both the original and modified geometries of this fuel system enclosure, the simulations provide insights into the flowpaths of leaking fuel, the spatial and temporal distribution of fuel vapor concentrations, and the overall effectiveness of design modifications aimed at rapid removal of hazardous substances. Structural improvements, including the addition of strategic ventilation inlets and outlets, are proposed based on the simulation results to ensure rapid dispersion of vapors and minimal residual fuel, effectively reducing the potential for vapor ignition. This study thus underscores the potential of precise CFD modelling in identifying risks and developing robust fire hazard mitigation strategies in aviation fuel systems.

PERCOLATION ON A TRIANGULAR LATTICE UNDER ANISOTROPIC CONDITIONS
Authors:   Faculty of Technical Sciences, University of Novi Sad, Budinski Petković Ljuba , Lončarević Ivana ,   Faculty of Technical Sciences, University of Novi Sad
Published: June 2024

The properties of percolation of objects of various shapes on a two-dimensional triangular lattice is studied by means of Monte Carlo simulations. Depositing objects of various shapes and sizes are made by directed self-avoiding walks on the lattice. Anisotropy is introduced by positing unequal probabilities for orientation of depositing objects along different directions of the lattice. This probability is equal p or (1−p)/2, depending on whether the randomly chosen orientation is horizontal or not, respectively. It is found that the percolation threshold θp increases with the degree of anisotropy, having the maximum values for fully oriented objects.

El necesario y complejo equilibrio entre los diversos sistemas de selección de funcionarios públicos
Authors: Sira-Santana Gabriel
Published: June 2024

Objetivos: estudiar la provisión por méritos y la designación política como sistemas de ingreso a la función pública, destacándose las ventajas y los retos que estos representan para la Administración en el marco de un Estado democrático de derecho y los principios que le resultan propios. Metodología: análisis de fuentes doctrinales y normativas nacionales e internacionales, así como comunicados de organizaciones internacionales que han estudiado la materia. Resultados: demuestran la relación que existe entre la Administración y la política como base de la evaluación de la legitimidad de los funcionarios públicos y sus roles de decisor o ejecutor de políticas públicas, lo que hace necesario un equilibrio en la implementación de ambos sistemas. Conclusiones: el sistema de méritos es un mecanismo que ha calado en la mayoría de las constituciones latinoamericanas al promover la objetividad, racionalidad e igualdad en el ingreso a los cargos públicos al evaluarse las cualidades de los candidatos y no a estos como sujetos allegados a quien designa. La designación política debe ser una excepción a la regla de la provisión por méritos, que lejos de promover la corrupción o el clientelismo debe utilizarse es para mejorar la gestión pública y el carácter democrático del Estado.

There is a vast literature on the occurrence of antibiotics and antibiotic resistant bacteria (ARB) of human or animal origin in natural aquatic ecosystems as result of anthropogenic activitie. Although hotspots for AR discharge in the environment were identified, that include: sewage and wastewater treatment plants (WWTP), industrial drug manufacurers, food and animal production, agriculture and aquaculture, and clinical settings such as hospitals, efficient current regulations to mitigate this pollution are lacking. The aim of this review is to provide insights regarding the spread of antibiotics and ARB from hotspots into aquatic environment and also an overview of current EU and UN regulations for combating AR pollution of our natural ecosystems.
Coverage Analysis and Proposed Cell Sizes to Enhance the Performance of the 5G Cellular System
Authors: Othman Bzhar Rahman , Alqaradaghi Thuraya Mahmood , Ameen Araz Sabir
Published: June 2024

The global demand for more digital data motivates the evolution of mobile communication systems from 2G and 3G to 4G and 5G to support high data rate applications. The International Mobile Telecommuication-2020 (IMT-2020) defined the minimum technical performance requirements and guidelines for evaluating the 5G mobile cellular system. The New Radio (NR) millimeter wave (mmWave) and massive Multiple Input Multiple Output (mMIMO) antenna systems are technologies used in the 5G cellular system. Therefore, this paper studies the performance of the mmWave system combined with the mMIMO antenna system using the IMT-2020 channel model in a dense urban microenvironment, considering different frequency bands and numbers of elements at the Base Station (BS) antenna array. The performance is evaluated through system-level simulation in terms of Signal power to Noise power Ratio (SNR), Spectral Efficiency (SE), and cell edge user SE. A cell size reduction technique is proposed to meet the target requirements set by IMT-2020. Simulation results showed that the sub. 6 GHz frequency bands achieve the target SE of IMT-2020, while in the mmWave frequency range, the target SE requirement can be achieved using a high number of antenna elements at the BS antenna for some frequency bands.
A leitura plataformizada na mídia digital: da sobrecarga informacional à perda do pensamento crítico
Authors: Hissa Débora Liberato Arruda
Published: June 2024

Neste artigo, partimos da hipótese de que o leitor de plataformas digitais como o Instagram constrói sentido por meio de frames organizados em metaenquadramentos visíveis na tela do celular. Cada frame se apresenta em porções textuais fragmentadas, ordenadas e alinhadas à barra de rolagem do feed presente na timeline de cada perfil. Examinamos o processo de agrupamento sequenciado por frames temáticos multissemióticos presentes em cada enquadramento retirado de prints da tela da plataforma pelo celular. Analisamos 120 postagens publicadas no Instagram, as quais foram divididas em seis grupos, cada um com vinte frames sequenciais. Os grupos foram separados em dois blocos: sessenta postagens de três contas pessoais; e sessenta postagens de três contas profissionais. Para descobrir padrões discursivos e relações lógico-semânticas nas plataformas, analisamos o material coletado a partir das categorias de referência, diálogo, estrutura da imagem, situação e intenção; e dos eixos especificidade da imagem, conexão, organização, referências visuais e interpretação. Vimos que cada frame é percebido pelo leitor como uma unidade autônoma de sentido, como se cada fatiamento encapsulado por um texto (notícia, propaganda, divulgação científica, meme) tivesse por si só a propriedade de significar com um alto grau de autonomia. A estratégia persuasiva de manutenção do leitor na plataforma é a constante ativação de novos referentes, além do alto teor de novidade e de imprevisibilidade de cada frames na plataforma. Esta combinação de novidade e imprevisibilidade promove um estado permanente de estimulação, o que pode gerar uma fragmentação da percepção, da memória e da compreensão leitora.
Deep brain stimulation for the heterogeneous pathophysiology of Parkinson’s disease
Authors: Dharnipragada Rajiv
Published: June 2024

Deep brain stimulation affects the pathophysiology of various motor disorders including essential tremor, Parkinson’s disease (PD) and dystonia. The motor deficits from PD have been explained by the firing rate and pattern models. However, due to the variability between patients’ electrophysiology, the pathophysiology for PD is difficult to sparse apart. Neither model can fully explain the spectrum of patient presentations. The localisation and stimulation of various structures including the subthalamic nucleus, globus pallidus internus and ventral intermediate nucleus lead to different effects on the patient’s motor symptoms. This group of targeted structures affects the models of PD in distinct ways. This review aims to explain the models of PD and the effects of stimulation in each structure.

The COVID-19 pandemic had influenced the global economy, including Indonesia’s tourism industry. The inability to mitigate these challenges had substantially jeopardized the sustainability of tourism, with social and economic consequences. This present study examines a case study of marine tourism in the eastern salient of Java, one of the most popular places in Java Island, to determine the relationship between fear of COVID-19, travel anxiety, and risk attitude toward travel intention. This study employed a quantitative method. The data was collected through surveys distributed online via google form and was analyzed using structural equation modeling – partial least square (SEM-PLS) in SmartPLS 3.0. The results show that the fear of COVID-19 has a positive impact on the travel anxiety, but not on the risk attitude; the travel anxiety has a positive impact on both the risk attitude and travel intention; the risk attitude has a positive impact on the travel intention, but the fear of COVID-19 does not.  The travel anxiety has a significant impact on the risk attitude and travel intention, while the travel anxiety has no significant impact on the risk attitude and travel intention. These findings suggest the Ministry of Tourism and Creative Economy of the Republic of Indonesia need to evaluate and monitor the operation of tourism destinations, as well as continuing to disseminate information about safe travel during the new normal era.JEL: Z33, M31.
First Principles Simulations of Optical Rotation of Chiral Molecular Crystals
Authors: Forson Emmanuel , Parsons Taylor , Caricato Marco
Published: June 2024

In this work, we present simulations of the optical rotation (OR) for five molecular crystals at density functional theory level with periodic boundary conditions (DFT-PBC). Calculations are compared with experimental measurements and show semi-quantitative agreement with experimental data for three of the crystals: tartatic acid, benzil, and pentaerythritol. For the other two crystals, aspartic acid and glutamic acid, the calculated data are in qualitative agreement with, but two orders of magnitude smaller than, the experimental data. We provide some arguments that support the theoretical predictions and suggest that the experiments should be revisited. We also find that the position of H centers provided in experimental X-ray data is not sufficiently reliable for simulating OR, and better results are obtained when H atoms are allowed to relax while keeping heavier elements fixed at the experimental positions. Comparison with molecular cluster calculations with a better functional and a larger basis set indicate that the role of intermolecular interactions (reproduced with the PBC technique) is as or more important than the choice of model chemistry. Despite the current limitations in the level of theory that can be employed, these simulations provide a promising avenue to investigate the effect of intermolecular interactions on this sensitive electronic property of molecules and materials.

Implementing inorganic filler particles is a powerful method for improving the mechanical properties of the formed composites. Fillers made of silicon dioxides can be found in countless polymeric materials. Because the interaction of the silica with the polymer determines the physical properties, factors like the surface-to-volume ratio (controlled via the particle size) and surface modification are important. Systems in which the particles are just physically dispersed in the polymer behave significantly differently to those for covalent anchoring of the fillers. Another possible functionality of the filler particles we focus on in the current publication is that they can bring stimuli-responsive properties to the system. Our concept is that photo-degradable organosilica nanoparticles can change the mechanical properties of a polymer/filler composite after it has been prepared. Because of the of the huge applicability of polysiloxanes ranging from building materials to medicine, silicones were selected as the center of interest for the current paper. After the synthesis of organosilica nanoparticles containing a bridging nitrobenzyl ether, and the investigation of the photochemical decomposition processes, the preparation of the composites is described. It is shown that vinyl groups attached to the surfaces are crucial for securing a homogeneous distribution of the filler particles inside the polymer matrix. Finally, the light-induced decomposition of the organosilica is executed and the mechanical properties are investigated by dynamic mechanical analysis. Other than expected, the material becomes stiffer. This effect is explained by a coupled increase of the surface-to-volume ratio of the silica particles accompanied by the emergence of hydroxy groups which interact with the polysiloxane backbone.

This study explores the application of computer-aided retrosynthesis (CAR) for developing greener and more efficient synthetic routes for the active pharmaceutical ingredient (API) IM-204, a helicase primase inhibitor with potential against Herpes simplex virus (HSV) infections. Using various CAR tools, several total synthetic routes were identified, evaluated, and experimentally validated, with the goal to maximize selectivity and yield and minimize the environmental impact. The selected route achieved a significant improvement in the overall yield of IM-204 synthesis from 8% to 35% while also enhancing GreenMotion metrics from 0 to 18 overall and reducing the cost of building blocks by 300-fold. This work demonstrates the potential of CAR in drug development, highlighting its capacity to streamline synthesis processes, reduce environmental footprint, and lower production costs, thereby advancing the field towards more efficient and sustainable practices.
Impacts of new printing technology on old conventional technologies
Authors: Mike FM Chungu
Published: June 2024

The movable type printing press was the signal innovation in early modern information technology, but economists have found no evidence of its impact on measures of aggregate productivity or income per person. This paper examines the impact technological advancement has brought to the printing industry. The printing industry has witnessed drastic changes in the machines used in this industry, such as automation and the elimination of other processes previously done. Additionally, it explores how the emergence of electronic media has affected the production of print media, leading to a decline in print media production. New technologies have benefited printing companies by reducing expenditures through the employment of fewer staff, but this also minimizes job opportunities in the printing industry. The paper also investigates whether printing companies and printers are satisfied with the new technologies being introduced.
Exact Analysis of MIMO Channel Estimation Based on Superimposed Training
Authors: Addad Mouad , Toaba Hanane Meriem , Djebbari Ali
Published: June 2024

In this paper, channel estimation capabilities of a multiple-input multiple-output (MIMO) system using superimposed training sequences are investigated. A new expression for estimation-error variance is derived. It is shown that the training sequences must be balanced and must have specific correlation properties. The latter are required only in a specific zone. Sequences that satisfy these criteria exist and are referred to as zero-correlation zone (ZCZ) solutions. Consequently, by using balanced ZCZ sequences, harmful direct current (DC) offset can be removed. Owing to their zero-cross correlation, interference from other transmitting antennas may be eliminated. Furthermore, a closed-form expression of the estimation-error variance can be obtained due to their impulse-like autocorrelation. To increase the number of antennas in the MIMO system, a new construction of ZCZ sequence set is proposed, in which all sequences are balanced
