An embarrassment of riches: What to do with a material 1 million times more nonlinear than silica
Authors: Boyd Robert W.
Published: October 2024

Research reported in 2016 [1] showed that materials such as indium tin oxide (ITO) display an unprecedentedly large nonlinear refractive index when excited at a frequency where the dielectric permittivity is nearly vanishing. The large nonlinear response of these epsilon-near-zero (ENZ) materials, some million times larger than that of silica glass, suggest that these materials would prove extremely useful in the development of new classes of photonic devices. In this contribution, we review the history of the understanding of nature of the nonlinear response of ENZ materials and the development of ENZ-based photonic devices. Specific investigations over the past eight years have led to increased under-standing of topics including (1) the origin of the enhancement of the nonlinear optical response, (2) the possibility of using nanofabrication methods to create ENZ behavior at any specified wavelength, and (3) the exploration of what interactions and devices are enabled through use of ENZ materials. In this contribution, we review the recent history of the development of the field of ENZ science and of the development of ENZ applications.
Closed-form formula for unequal channel allocation to reduce FWM crosstalk in DWDM long-haul networks
Authors: Fahd Chaoui , Abdellah Yassine El Harrak , Mounia Chakkour , Otman Aghzout
Published: October 2024

Dense wavelength division multiplexing (DWDM) is considered as a mainstream solution for 5G optical transmission networks to confront increasing bandwidth demand. In such a dense multiwavelength system, the four wave mixing (FWM) non-linear effect limits the achievable transmission distance and channel capacity. For this reason, and to the best of our knowledge, a new unequal channel allocation (UCA) has been introduced in this paper based on new closed-form equations to reduce the FWM crosstalk in the DWDM optical long-haul network. The proposed channel allocation has been investigated based on several design parameters that affect FWM nonlinear crosstalk, such as total transmission distance, channel frequency spacing, the number of WDM channels, and the input power per channel. The suggested technique has further been compared with a previous model proposed by other authors to prove the effectiveness of this work. The simulation results have been examined and validated by analysing the optical spectrum analyser and the power of the FWM spectral products. Results demonstrate the reliability and the efficiency of the developed method.
Evaluation and analysis of the electro-optic effect and the Stark effect in electro-optic polymers by the simple transmission measurement technique without an aperture
Authors: Yamada Toshiki , Otomo Akira
Published: October 2024

A simple and reliable transmission measurement technique without an aperture was utilized to evaluate both the electro-optic (EO) effect and the Stark effect of EO polymers. For some EO polymers, both the EO effect and the Stark effect were evaluated using laser light sources with various wavelengths of 1550 nm, 1308 nm, 980 nm, and 640 nm and the analysis method was also described. We showed that both the magnitude and the phase of the modulated light signal in lock-in detection at both the π/2 and 3π/2 points are very important for appropriate analysis.

Published: October 2024

Plasma is the optimal choice for acquiring and modulating the extremely
high visible and near-infrared light. However, few attempts have been
made to apply this strategy for the terahertz (THz) wave modulation in
an ex situ manner. Here, we show a
laser-driven plasma-based THz modulator (PTM) to ex situ control the incident THz waves. The presented PTM
allows for the amplification or extinction of the incident THz waves
covering 0.1–2.0 THz within a few picoseconds, simply by
adjusting its dipole phase. This modulation is a result of the
interaction between the PTM’s dipole and THz wave, which can be
accurately reproduced by the spectral analysis method. Our technique
offers promising opportunities to explore the plasma-based THz optics
and potential applications across different disciplines, such as
THz-sensing and near-field THz technology.

Dog–human vocal interactions match dogs’ sensory-motor tuning
Authors: Déaux Eloïse C. , Piette Théophane , Gaunet Florence , Legou Thierry , Arnal Luc , Giraud Anne-Lise
Published: October 2024

Within species, vocal and auditory systems presumably coevolved to converge on a critical temporal acoustic structure that can be best produced and perceived. While dogs cannot produce articulated sounds, they respond to speech, raising the question as to whether this heterospecific receptive ability could be shaped by exposure to speech or remains bounded by their own sensorimotor capacity. Using acoustic analyses of dog vocalisations, we show that their main production rhythm is slower than the dominant (syllabic) speech rate, and that human–dog-directed speech falls halfway in between. Comparative exploration of neural (electroencephalography) and behavioural responses to speech reveals that comprehension in dogs relies on a slower speech rhythm tracking (delta) than humans’ (theta), even though dogs are equally sensitive to speech content and prosody. Thus, the dog audio-motor tuning differs from humans’, and we hypothesise that humans may adjust their speech rate to this shared temporal channel as means to improve communication efficacy.
Experience-dependent serotonergic signaling in glia regulates targeted synapse elimination
Authors: Miller Vanessa Kay , Broadie Kendal
Published: October 2024

The optimization of brain circuit connectivity based on initial environmental input occurs during critical periods characterized by sensory experience-dependent, temporally restricted, and transiently reversible synapse elimination. This precise, targeted synaptic pruning mechanism is mediated by glial phagocytosis. Serotonin signaling has prominent, foundational roles in the brain, but functions in glia, or in experience-dependent brain circuit synaptic connectivity remodeling, have been relatively unknown. Here, we discover that serotonergic signaling between glia is essential for olfactory experience-dependent synaptic glomerulus pruning restricted to a well-defined Drosophila critical period. We find that experience-dependent serotonin signaling is restricted to the critical period, with both (1) serotonin production and (2) 5-HT2A receptors specifically in glia, but not neurons, absolutely required for targeted synaptic glomerulus pruning. We discover that glial 5-HT2A receptor signaling limits the experience-dependent synaptic connectivity pruning in the critical period and that conditional reexpression of 5-HT2A receptors within adult glia reestablishes “critical period-like” experience-dependent synaptic glomerulus pruning at maturity. These results reveal an essential requirement for glial serotonergic signaling mediated by 5-HT2A receptors for experience-dependent synapse elimination.

Published: October 2024

The continued scaling of genetic perturbation technologies combined with high-dimensional assays such as cellular microscopy and RNA-sequencing has enabled genome-scale reverse-genetics experiments that go beyond single-endpoint measurements of growth or lethality. Datasets emerging from these experiments can be combined to construct perturbative “maps of biology”, in which readouts from various manipulations (e.g., CRISPR-Cas9 knockout, CRISPRi knockdown, compound treatment) are placed in unified, relatable embedding spaces allowing for the generation of genome-scale sets of pairwise comparisons. These maps of biology capture known biological relationships and uncover new associations which can be used for downstream discovery tasks. Construction of these maps involves many technical choices in both experimental and computational protocols, motivating the design of benchmark procedures to evaluate map quality in a systematic, unbiased manner. Here, we (1) establish a standardized terminology for the steps involved in perturbative map building, (2) introduce key classes of benchmarks to assess the quality of such maps, (3) construct 18 maps from four genome-scale datasets employing different cell types, perturbation technologies, and data readout modalities, (4) generate benchmark metrics for the constructed maps and investigate the reasons for performance variations, and (5) demonstrate utility of these maps to discover new biology by suggesting roles for two largely uncharacterized genes.
Development of optimal indoor air disinfection and ventilation protocols for airborne infectious diseases
Authors: Park Jooyeon , Lee Kyoung Hwa , Song Young Goo , Park Hyungmin , Lee Kwang Suk
Published: October 2024

Since the COVID-19 pandemic, there has been persistent emphasis on the importance of indoor air disinfection and ventilation in isolation units in the hospital environment. Nevertheless, no optimal and concrete disinfection protocol has been proposed to inactivate the viruses as quickly as possible. In this study, we experimentally evaluated various ventilation and disinfection protocols based on the combination of negative-pressure ventilation, ultraviolet (UV) light illumination, and Hypochlorous acid (HOCl) spray against three active virus species in a 3.5 cubic meters isolation unit. This small-size unit has gained attention during the pandemic due to the high demand for compact mobile laboratory systems capable of rapid disease diagnosis. In accordance with the WHO laboratory biosafety guidance, which states that all enclosed units where diagnostic work is conducted must ensure proper ventilation and disinfection activities, we aim to propose virus removal protocols for units compact enough to be installed within a van or deployed outdoor. The results confirmed the superiority (in terms of virus removal rate and time required) of the virus removal methods in the order of UV light, ventilation, and HOCl spray. Ultimately, we propose two optimal protocols: (i) UV light alone for three minutes, and (ii) UV light with ventilation for three minutes, followed by one-minute ventilation only. The time span of three minutes in the latter protocol is based on the clinical practice such that the medical staffs have a sufficient time to process the samples taken in transition to next patient to care.
Stripe pattern differences can be used to distinguish individual adult zebrafish
Authors: Meguro Shinichi , Hasumura Takahiro
Published: October 2024

Adult zebrafish are commonly used as disease models in biomedical research, but unlike in other model organisms such as rodents, there is no simple method for distinguishing individuals, even though the importance of individual differences is recognized in such research. We developed a side viewing device that can be used to capture images of stripe patterns and identified eight distinct components of stripe patterns on the caudal and anal fins that allowed us to distinguish individual fish. We found that the stripe patterns were consistent for at least 8 weeks in males and females of two lines of wild-type zebrafish. These results suggest that individual adult zebrafish can be distinguished in an easy and non-invasive manner, allowing researchers to incorporate individual differences in biomedical research as in rodent models.

Published: October 2024

This study aimed to analyze the profile of hospitalizations sensitive to primary care in the elderly according to age and sex. This is an ecological study with description of sensitive hospitalizations of elderly residents in the city of Uberaba - MG from 2009 to 2018. The proportion of hospitalizations for sensitive conditions compared to the total number of hospitalizations and the rates of sensitive hospitalizations were analyzed. For the other analyzes, the causes of hospitalization by age and sex were analyzed, and descriptive analyzes were carried out in terms of frequency and percentage. The proportion of sensitive hospitalizations decreased in the period between 2009 and 2016, with the most expressive groups of causes related to the cardiovascular system (heart failure, angina, and cerebrovascular diseases), elderly people aged 80 years and over and male. Ecological studies with public domain data are of fundamental importance in the analysis of the health conditions of the populations and in the direction of the health actions undertaken, especially those carried out by Primary Health Care (PHC).

This study aimed to identify and evaluate the antimicrobial susceptibility profile of extended-spectrum β-lactamase (ESBL)-producing Enterobacterales isolated from blood cultures of patients with suspected sepsis. This retrospective cross-sectional epidemiological study was performed for four years (2015 to 2018) by accessing the medical records of patients diagnosed with bloodstream infections in two tertiary public hospitals in Brazil. Culture results and susceptibility tests of bacterial strains isolated from blood samples were analyzed. During four years, 2,263 blood culture exams were performed, and Enterobacterales were isolated in 694 (30.7%) samples. The disk approximation test detected ESBL production in 171 (24.6%) of the 694 isolated Enterobacterales (p<0.05), with 125 (73.1%) corresponding to Klebsiella spp., 28 (16.2%) to Escherichia coli, eight (4.6%) to Enterobacter spp., five (2.9%) to Serratia spp., three (1.7%) to Proteus spp., and two (1.2%) to Citrobacter spp. All tested antibiotics demonstrated low susceptibility (2.9% to 26.9%). The classes of monobactams, cephalosporins, and penicillin showed high resistance indices. The evaluated Enterobacterales isolates exhibited expressive antimicrobial resistance to drugs commonly used as empirical treatment in bloodstream infections. The findings reinforce the relevance of assessing the bacterial antimicrobial susceptibility profile, as it drives antibiotic therapy, potentially detecting multiresistance cases.
Evaluation of behavioral responses to restraint stress in the house mouse (Mus musculus musculus) of wild origin
Authors: Klyuchnikova Maria A.
Published: October 2024

Stress is a fundamental concept for many areas of animal research. In laboratory rodents, exposure to various stressors results in immediate and postponed behavioral changes that can be measured with standard tests. Less is known about how wild rodents that have not undergone domestication respond to stressors in laboratory settings. This study was aimed at evaluating behavioral responses to restraint stress in male and female wild-derived house mice (Mus musculus musculus). One week after the end of three daily restraint sessions, alterations in mouse behavior were assessed in two tests. In the open field test, stressed mice (n = 23) entered the unprotected central zone less frequently (P < 0.05) and showed increased duration of self-grooming (P < 0.05) compared to controls (n = 23), indicating elevated anxiety. In the forced swim test, most mice (44 out of 46) displayed episodes of behavioral despair, but the influence of stress was insignificant. To characterize baseline performance of wild-derived mice, their behavior was compared to that of a laboratory strain. As compared to C57BL/6 males (n = 10), M. m. musculus males (n = 14) showed significantly greater exploratory activity in the open field and longer latency of the first immobility episode in the forced swim test (P < 0.001). Overall, these findings confirm ecological validity of the widely used animal model of restraint stress and may serve as a basis for future studies.
Navigating Sharia and Institutional Conflict: The Case of Land Pawning Practices in Aceh
Authors: Afna Mauloeddin Afna
Published: October 2024

Sharia-based pawning practices in Aceh have long served as an important system for managing communal assets and fostering social cohesion. However, recent challenges, such as declining trust, rising gold prices, and misinterpretations of Sharia principles, have jeopardized the sustainability of this system. This study aims to explore the social, economic, and cultural dynamics that contribute to conflicts within Aceh’s pawning system, with a focus on how stakeholders address and resolve these conflicts. Employing a Participatory Action Research (PAR) approach, the study gathered data through literature reviews, interviews, and participant observation, involving local authorities, religious leaders, and community members. The research investigates how institutional logics—religious, cultural, and economic—shape conflict resolution strategies in the community. The findings indicate that while economic pressures and misapplications of Sharia principles drive these conflicts, successful resolution depends heavily on cooperation among stakeholders. The community’s role as mediator is critical in ensuring transparency, trust, and fairness. The study concludes that achieving a balance between Sharia compliance and local socio-economic realities is key to fostering sustainable reforms and ensuring the long-term stability of the pawning system in Aceh.

A High Performance Parallel Approach to Delay Sum Beamformer in a Homogeneous Multicore Environment
Authors: Narayanan M. Prakash , Gopal G. Vijay , Rajesh R.
Published: October 2024

A Cache-Aware Beamformer (CABF) algorithm for the DAS beamformer in a homogeneous multicore processor environment is presented. The context of the proposed algorithm is established by discussing the case for a refined multicore implementation of the beamformer algorithm for a sonar application. The algorithm is designed, implemented, and compared to a regular pthread multicore implementation and a standard OpenMP-based implementation, using arithmetic intensity as the metric. FMA implementations of the algorithms are carried out, and the CABF algorithm is shown to achieve a better arithmetic intensity. A 6000-element array is designed with a simultaneous forming of 200 beams to test the efficacy of cabf in a multicore platform. The results show a 73 % increase in GFLOPS for FMA operations. The performance of the beamformer algorithm for different data sizes is studied, and on average, a 36 % improvement in computational performance is achieved compared to the OpenMP-based implementation.
Conceptual Design Process of a Missile Model and Production Using Additive Manufacturing Method
Authors: AY Nisa , Bozdemir Mustafa
Published: October 2024

This study focuses on air-to-ground missile systems, which are widely used in Turkey and around the world and are becoming increasingly important. The development of missile systems takes into account various requirements defined by the end user. It is important to identify a system and its subcomponents that fully meet the requirements. This study analyzes an air-to-ground missile system and its main subcomponents identified through the conceptual design method based on the systematic design approach proposed by Pahl and Beitz. The aim is to determine the feasibility of obtaining an optimal solution that meets the requirements set by the conceptual design method. The missile design’s optimal solution was modeled using SolidWorks software. A three-dimensional (3D) printer with FDM production technology was used to produce a prototype of the computer-modeled design. ABS and ABS-plastic blend filaments were preferred due to their material properties in the FDM production process. During the printing stage, the filament and output settings of the model were determined using the 3D printer’s interface program. The filaments were then extruded through a nozzle, following the cross-sectional geometry of the part. The resulting model was printed in pieces and assembled with a tolerance of 0.1mm. This process resulted in a 3D model of the missile, which was created to represent the system structure in different colours. The study demonstrates that the conceptual design method can be used to develop innovative and meaningful missile models.

Published: October 2024

With the intensification of new classes of media such as Twitter, the Internet has become a primary route for individual and interpersonal messaging. Many individuals share their thoughts regarding news-related topics on Twitter, an established SNS network built on people’s relationships. It offers us with a Source of data from which we can dig people’s thoughts, which is useful for product reviews and community monitoring. A Hybrid Emotional Recognition Model (HERM) is proposed in this research. Hashtags are recognized as the tag for emotional cataloging based on gathered posts from Twitter. Meanwhile, emoji and the N-grams are dug and used to classify the gathered topic comments into four distinct sentiment groups using the distorted emotional models. Machine learning approaches are applied of categorizing the emotional information set, yielding an 92 % accuracy result. Furthermore, entities underlying emotions might be obtained using the deep learning model SENNA.
Investigations on Penta Band High Isolation MIMO Antenna for 5G NR Bands and HIPERLAN Applications Using TCMA
Authors: Himaja Makkapati , Yuvaraj S.
Published: October 2024

The present article proposes a penta band Multiple Input Multiple Output (MIMO) antenna for 5G New Radio (NR) bands and HIPERLAN applications using Characteristic Mode Analysis (CMA). The design is obtained and optimised in step-by-step procedure using novel CMA approach and by perturbing the conventional rectangular structure with slots on the patch (left and right sides) and the ground plane (wide slot + narrow slots) for enhancing the isolation at multi bands. The MIMO configuration has a total dimension of 0.58 l0 × 0.35 l0 × 0.01 l0 mm3 with an optimum element separation of 0.05 l0 (l0 is the lowest frequency operating wavelength). Multiband resonance is produced at 2.2, 4.2, 7.2, 16, 17.5 GHz. The radiating elements can excite various characteristic modes that support wider bandwidth. The -10 dB impedance bandwidth at working region are 0.2, 0.2, 0.38, 3.6, 2 GHz respectively. The suggested design yields a gain of 2.1, 5.7, 3.5, 3.5, 5.2 dBi and consistent radiation patterns at the working frequencies. The analysis of the diversity performance considers the Diversity Gain (DG) and Envelope Correlation Coefficient (ECC), whose values are near 9.9 dB and 0, respectively. Additionally, the assessed parameters are the CCL and TARC. The structure prototype has been developed, and the observed findings are highly coherent with the simulated results, making it appropriate for use in 5G NR bands, HIPERLAN, and IoT applications.
Falacia naturalista, falacia de composición en John Stuart Mill
Authors: Urueta Vladimir
Published: October 2024

El siguiente artículo aborda la crítica que manifiesta que John Stuart Mill incurrió en la falacia naturalista y en la falacia de composición. Esta temática se puede abordar de dos formas: una consistiría en analizar si Mill realmente desconoce la distinción entre lo deseado y lo deseable; otra sobre si su concepción de hedonismo, felicidad, conlleva la comisión de las falacias mencionadas. Esta última forma es el tema principal que se aborda; en otras palabras, se mencionará brevemente lo relativo a si Mill confunde deseado/deseable, es/debe, y se puntualiza en cómo el hedonismo y la idea de felicidad millianos no llevan a caer en la falacia naturalista ni en la falacia de composición. En todo esto la educación jugará un papel valioso.

The effects of posture on athletic performance have been the focus of attention of many researchers and the importance of body posture in achieving success has become undeniable. This study aimed to perform the postural evaluation of adolescent youth athletes who are trained in basketball, soccer, volleyball, and swimming branches. A total of 88 adolescent athletes (32 boys and 56 girls) with an average age of ±12.37 years, an average height of ±1.58 cm, an average body weight of ±48.2 kg, an average BMI of ±18.19 and an average training age of ±2.06 years from football, volleyball, and swimming branches actively active in Manisa and Bursa provinces participated in the study. Posture analysis of the athletes was performed using the Apecs-AI Posture Evaluation and Correction System® mobile posture application. The data obtained from the athletes were evaluated with the NewYork Posture Assessment Test (NYPD). The data obtained from the study were analyzed using the SPSS 22.0 package program.  One-way Analysis of Variance (ANOVA) was used for independent samples. According to the results of the analysis, there was a significant difference between training age and NYPD scores according to branches (p<.05).  Significance was found between NYPD and body axis scores in volleyball and soccer athletes (p<.05). There was no difference between NYPD and other variables in swimming and basketball. As a result, it is thought that the effect of the training age variable on posture structures differs specifically according to the branches, and posture is negatively affected as the training age increases in volleyball and soccer players.

Objective: Anamnesis, extraoral intraoral examination, radiographic examination, and other special examination methods are used to diagnose diseases in the oral and maxillofacial regions. The aim of this study was to establish the demographic, systemic, and radiographic characteristics of the patients by analyzing the records of patients who were treated at the Oral and Maxillofacial Radiology Clinic of the University Faculty of Dentistry. Methods: The anamnesis and diagnostic records of patients who were treated at the OMR clinic between 01.01.2013 and 31.12.2019 and the radiographic records of the patients referred to the X-ray department were retrospectively analyzed. The number of patients was analyzed according to demographic, systemic, and radiographic classifications, and tables were created according to years and total numbers. Results: The number of females who applied between 2013-2019 was statistically significantly higher than that of males. When the age distribution of all patients who applied to the OMR clinic was analyzed, it was observed that the patients who applied were 15 years of age and older, and 29.3% of these patients were in the 30-44 age group, with the highest proportion. When radiographic data were analyzed, it was observed that the most common radiograph obtained was a panoramic radiograph (90%). Conclusion: Anamnesis records revealed the systemic disease characteristics of the study area, which is helpful for diagnosis and treatment planning. The most requested radiographic types and clinics that requested the most radiographs were determined. This will help improve the functioning within and between departments. By determining the common diagnoses in panoramic radiographs, the issues to be considered in patients of certain age and sex groups have been clarified.
The Construction of Women As The Loving Subject In Curtis Sittenfield's Eligible
Authors: Asri Zietha Arlamanda
Published: October 2024

Women's presence as the dominant figure in the construction of patriarchal society is an emerging issue presented by Curtis Sittenfeld in her Novels. Liz is one of the female characters Curtis Sittenfeld displays in her novel Eligible. This figure of women who appear in her novel is very complex with many various dynamics. This study aims to examine the female main character as a loving subject in a male-dominated society. Applying Giddens's theory of loving subjects, the study's results revealed that Liz is described as the loving subject who seeks to build an intimate relationship with the man who became her choice. Through her behaviour and appearance, she was described as a loving subject who has a smooth character, sensitive and romantic. Liz is also shown as a private autonomous and has humanist and psychological dimensions, which are very complex inside. Curtis Sittenfeld as a writer presents the presence of women as the loving subject in a relationship of intimacy that is liquid and unrestricted.  In this research, women are presented as an autonomous entity that has the same rights in a male-dominated society.

Queen Charlotte: A Bridgerton Story is one of the popular Netflix series in 2023. This series is famous for being the aftermath of the two Bridgerton series that were released previously. The story, which is set in the British Empire at the end of the 18th century, attracts the attention of audiences. It is prominent to apply into the theory used because the various social factors and dimensions in the series can provide the samples of the five types of language styles according to Joos (1967), from frozen styles to intimate styles. The data used in this study are Charlotte’s utterances to the three main supporting characters. Data collection uses the observation method by analyzing the dialogues in the series. There are 373 data found with the style that appears most often is the casual style. This type of language style is usually used in informal situations, with intimate relationships between participants.
Komplex nadřazenosti. „Naše“ versus „cizí“ v českém užitém umění mezi světovými válkami
Authors: Knobloch Iva
Published: October 2024

André Gide described Soviet attitudes towards the outside world in the 1930s as a manifestation of a superiority complex. And it seems to me that the proclamations of representatives of architecture, applied arts and professional art education in the Czech lands between 1918 and 1925, when they created a “national” or “state” style, do not differ much from these attitudes in many ways.
In the texts of Pavel Janák, Otakar Novotný, Jaroslav Benda, V. V. Štech and others, the pronoun “our” occurs most often, which seems to have been generally accepted without further explanation; the opposite is “foreigners” who have nothing more to offer “us” – as the above-mentioned representatives of the Czechoslovak Werkbund, an organization that has set itself the goal of raising the level of housing culture and the environment of life in general, assure themselves. It manifestly promoted “domestic values and domestic spirit”, which are embodied in Slavic poetic, emotional, melodic works, suitable for the mood of “our people”, who were defined as a small, modest person, an ordinary descendant of farmers and village teachers. He is satisfied with the “provinciality”, the “obsolescence” of “our” art, because it reflects “our” conditions.
Although the textual programmes of the representatives of the state, national style come to terms with the position of Czech applied art and architecture on the world stage in an immature way, the actual results of their artistic work no longer have to be evaluated from the modernist perspective as a dead end, but as distinctive manifestations of international modern decorativism, despite the isolationist ideas of the creators at the time.
Nacionalismus vs. internacionalismus. Karel Hlaváček mezi Moderní revue a sokolstvím
Authors: Urban Otto M.
Published: October 2024

The paper deals with the concept of nation, or Czechness, in the views of the poet, theoretician and artist Karel Hlaváček (1874–1898). In the mid-nineties of the 19th century, Hlaváček belonged to the inner circle around the magazine Moderní revue. In this environment, issues related to national identity, especially in the field of art and culture, but also in the political and social context, were often discussed. At that time, however, Hlaváček was also active in the Sokol association, whose national, i.e. Czech, dimension was not negligible. The texts he published in the Sokol press often differed significantly from those in the pages of Moderní revue, even in terms of the concept of the nation. The difference between the well-known text Nacionalism a internationalism (Moderní revue, December 1896) and his extensive study of Sokol as a social movement, which he published a few months later in the magazine Sokol (October 1897), is absolutely crucial. Hlaváček’s views will be placed in the broader intellectual context of European decadent art.

Authors: Yadav Komal Singh , Sharan Bhagwat , Verma Ashish
Published: October 2024

We introduce new extension of the extended Pochhammer symbol and gamma function by using the extended Mittag-Leffler function. We also present extension of the generalized hypergeometric function as well as some of their special cases by using this extended Pochhammer symbol. Further, we define the extension of the τ-Gauss hypergeometric function. Integral and derivative formulas involving the Mellin transform and fractional calculus techniques associated with this extended τ-Gauss hypergeometric function are also given. Also, new extended τ-Gauss hypergeometric function also provides a few more interesting and well-known results. This enriches the theory of special functions. The obtained results are believed to be newly presented.
