Teknologi jaringan komunikasi merupakan serangkaian komponen teknologi yang saling berhubungan antara satu dengan yang lainnya. Salah satu di antaranya yang banyak di gunakan dalam kehidupan sehari-hari yaitu teknologi jaringan 4G. Dengan adanya jaringan tersebut akan mempermudah kebutuhan akan internet sehari-harinya. Namun perbedaan kecepatan dalam mengakses perlu akan adannya pengujian dan pembahasan suatu jaringan dalam layanan yang baik dan juga perlu adanya layanan Quality Of Service(QOS) yang baik pula. Dalam pengujian Teknologi jaringan 4G ini berfokus hanya pada lima parameter QOS saja yaitu : Throughput, Delay, Jitter, Packet loss dan Bandwidth. Dalam pengukuran performa teknologi jaringan 4G menggunakan layanan Quality Of Service (QOS), analisa dan pengujian yang di lakukan untuk mengetahui reperentasi pada kondisi jaringan pada saat ini. Dari hasil penelitian ini, didapatkan perbedaan yang tidak begitu signifikan antara masing-masing operator jaringan. Meski tidak begitu signifikan operator jaringan TELKOMSEL memiliki hasil yang lebih baik di banding operator XL maupun INDOSAT. Dari hasil penelitian ini dari ketiga operator jaringan tersebut dapan di gunakan sebagai pertimbangan bagi user dalam memilih penggunaan internet sesuai dengan kebutuhan masing-masing.

Communication network technology is a series of technological components that are interconnected with one another. One of them that is widely used in everyday life is 4G network technology. With this network, it will facilitate the need for daily internet. However, the difference in speed in accessing the need for testing and discussing a network in good service and also the need for good Quality Of Service (QOS) services as well. In testing 4G network technology, it focuses only on five QOS parameters, namely: Throughput, Delay, Jitter, Packet loss and Bandwidth. In measuring the performance of 4G network technology using Quality Of Service (QOS) services, analysis and testing are carried out to determine the representation of current network conditions. From the results of this study, it was found that the difference between each network operator was not so significant. Although not so significant, TELKOMSEL network operators have better results than XL and INDOSAT operators. From the results of this study of the three network operators can be used as a consideration for users in choosing internet usage according to their individual needs.

Estimating age-dependent performance in paired comparisons competitions: application to snooker
Authors: Baker Rose D. , McHale Ian G. 
Published: February 2024

Abstract
We first present a model for the outcome of snooker matches in which player strengths are allowed to vary deterministically with time. The results allow us to identify the greatest players of all time, and to examine the relationship between age and performance. Second, we present a random effects model which uses the estimated strengths from our first model, to forecast player performance, and to assess the extent to which early promise has been maintained. Ronnie O’Sullivan and Stephen Hendry are the two candidates for the title of the greatest of all time. We find that peak performance occurs between the ages of 25 and 30, younger than would be expected when compared to findings in other sports. Outside sport, these findings contribute to the general literature on variation of performance with age.

Abstract

Objectives
To evaluate the ovarian reserve (OR) in women with antiphospholipid syndrome (APS), systemic lupus erythematosus (SLE), especially SLE-associated APS, and to determine the association between OR and clinical and laboratory parameters.

Methods
We compared the antral follicle count (AFC), anticardiolipin antibody, and anti-Müllerian hormone (AMH), inhibin B (INHB), antiphospholipid (aPL) antibody, follicle-stimulating hormone (FSH), progesterone (P), testosterone (T), and estradiol (E2) among patients with primary APS (PAPS), SLE-APS, and SLE who were treated at Jinhua Central Hospital between 2017 and 2020. We conducted correlations and logistic regression analyses to identify the risk factors of OR failure in women with APS.

Results
Serum AMH were positively correlated with AFC and INHB in APS patients, and low AMH was independent risk factor for OR decline in APS patients. The ROC curve showed a high accuracy for AMH in the prediction of OR failure. Compared to healthy subjects (HS), patients with PAPS, SLE-APS, and SLE exhibited lower serum AMH, AFC, INHB, and E2 levels and higher FSH and levels (p<0.05). Of all the patients, those with SLE-APS manifested the lowest serum AMH, AFC, INHB, and E2 levels and the highest FSH levels (p<0.05).

Conclusions
APS and SLE patients showed lower indications of OR, including AFC and AMH, compared to HS. SLE-APS patients also appeared to have a lower OR than either SLE or PAPS patients.
Truthmaking. Are Facts Still Really Indispensable?
Authors: Mzyk Błażej 
Published: February 2024

Abstract
In recent years there has been a lot of skepticism about the existence of facts. It seems that one of the last places for their application is in truthmaking theory. In this paper I discuss two approaches to the use of facts in truthmaking. The first, categorial, holds that facts are entities that belong to one of three ontological categories (true propositions, truth of propositions, instantiations of universals). The second, deflationary, holds that a fact is merely a functional concept denoting any entity that performs a truthmaking function. I argue that in the face of significant criticism of categorial facts as truthmakers, a defender of facts may resort to the deflationary concept. Nevertheless, even in this case we can do without facts as truthmakers.
Theoretical model of passive mode-locking in terahertz quantum cascade lasers with distributed saturable absorbers

Published: February 2024

Abstract
In research and engineering, short laser pulses are fundamental for metrology and communication. The generation of pulses by passive mode-locking is especially desirable due to the compact setup dimensions, without the need for active modulation requiring dedicated external circuitry. However, well-established models do not cover regular self-pulsing in gain media that recover faster than the cavity round trip time. For quantum cascade lasers (QCLs), this marked a significant limitation in their operation, as they exhibit picosecond gain dynamics associated with intersubband transitions. We present a model that gives detailed insights into the pulse dynamics of the first passively mode-locked QCL that was recently demonstrated. The presence of an incoherent saturable absorber, exemplarily realized by multilayer graphene distributed along the cavity, drives the laser into a pulsed state by exhibiting a similarly fast recovery time as the gain medium. This previously unstudied state of laser operation reveals a remarkable response of the gain medium on unevenly distributed intracavity intensity. We show that in presence of strong spatial hole burning in the laser gain medium, the pulse stabilizes itself by suppressing counter-propagating light and getting shortened again at the cavity facets. Finally, we study the robustness of passive mode-locking with respect to the saturable absorber properties and identify strategies for generating even shorter pulses. The obtained results may also have implications for other nanostructured mode-locked laser sources, for example, based on quantum dots.
Advances in fundamentals and application of plasmon-assisted CO2 photoreduction

Published: February 2024

Abstract
Artificial photosynthesis of hydrocarbons from carbon dioxide (CO2) has the potential to provide renewable fuels at the scale needed to meet global decarbonization targets. However, CO2 is a notoriously inert molecule and converting it to energy dense hydrocarbons is a complex, multistep process, which can proceed through several intermediates. Recently, the ability of plasmonic nanoparticles to steer the reaction down specific pathways and enhance both reaction rate and selectivity has garnered significant attention due to its potential for sustainable energy production and environmental mitigation. The plasmonic excitation of strong and confined optical near-fields, energetic hot carriers and localized heating can be harnessed to control or enhance chemical reaction pathways. However, despite many seminal contributions, the anticipated transformative impact of plasmonics in selective CO2 photocatalysis has yet to materialize in practical applications. This is due to the lack of a complete theoretical framework on the plasmonic action mechanisms, as well as the challenge of finding efficient materials with high scalability potential. In this review, we aim to provide a comprehensive and critical discussion on recent advancements in plasmon-enhanced CO2 photoreduction, highlighting emerging trends and challenges in this field. We delve into the fundamental principles of plasmonics, discussing the seminal works that led to ongoing debates on the reaction mechanism, and we introduce the most recent ab initio advances, which could help disentangle these effects. We then synthesize experimental advances and in situ measurements on plasmon CO2 photoreduction before concluding with our perspective and outlook on the field of plasmon-enhanced photocatalysis.

BACKGROUND
Respiratory syncytial virus (RSV) is the leading cause of hospitalization in US infants. Accurate estimates of severe RSV disease inform policy decisions for RSV prevention.

METHODS
We conducted prospective surveillance for children &lt;5 years old with acute respiratory illness from 2016 to 2020 at 7 pediatric hospitals. We interviewed parents, reviewed medical records, and tested midturbinate nasal ± throat swabs by reverse transcription polymerase chain reaction for RSV and other respiratory viruses. We describe characteristics of children hospitalized with RSV, risk factors for ICU admission, and estimate RSV-associated hospitalization rates.

RESULTS
Among 13 524 acute respiratory illness inpatients &lt;5 years old, 4243 (31.4%) were RSV-positive; 2751 (64.8%) of RSV-positive children had no underlying condition or history of prematurity. The average annual RSV-associated hospitalization rate was 4.0 (95% confidence interval [CI]: 3.8–4.1) per 1000 children &lt;5 years, was highest among children 0 to 2 months old (23.8 [95% CI: 22.5–25.2] per 1000) and decreased with increasing age. Higher RSV-associated hospitalization rates were found in premature versus term children (rate ratio = 1.95 [95% CI: 1.76–2.11]). Risk factors for ICU admission among RSV-positive inpatients included: age 0 to 2 and 3 to 5 months (adjusted odds ratio [aOR] = 1.97 [95% CI: 1.54–2.52] and aOR = 1.56 [95% CI: 1.18–2.06], respectively, compared with 24–59 months), prematurity (aOR = 1.32 [95% CI: 1.08–1.60]) and comorbid conditions (aOR = 1.35 [95% CI: 1.10–1.66]).

CONCLUSIONS
Younger infants and premature children experienced the highest rates of RSV-associated hospitalization and had increased risk of ICU admission. RSV prevention products are needed to reduce RSV-associated morbidity in young infants.
“Some Sort of Machine without a Body”
Authors: Reisinger Elisabeth 
Published: February 2024

AbstractFrom the mid-1950s, Basel harpsichordist Antoinette Vischer (1909–1973) promoted the harpsichord as a modern instrument, commissioning numerous composers to contribute to a new repertoire. To this end, she turned to György Ligeti, who completed Continuum for her in 1968. The composer had already used the harpsichord in ensembles several times, but now he had to think about it in a soloistic function for the first time, starting from a specific performer with her specific instrument. In this paper, I focus on this relationship between composer, performer-commissioner, and instrument, drawing primarily on the correspondence between Ligeti and Vischer preserved at the Paul Sacher Foundation in Basel. These unpublished letters document their collaboration and how both negotiated their artistic positions and aesthetic concepts of the harpsichord as “some sort of machine.” An in-depth analysis of Ligeti and Vischer's exchange about the instrument's peculiarities and performance issues allows us to better understand their self-conception as artists and their ideas of “modernity.” Furthermore, this case study sheds light on a specific period in the history of an instrument that through the efforts of performers like Vischer was transformed from an artifact of the past to an emblem of the present.
Reports and Conjectures on Kylwiria
Authors: Zimmermann Heidy 
Published: February 2024

AbstractThe code word “Kylwiria” was mentioned by György Ligeti from time to time since the 1970s. At first, it functioned rather abstractly as a working title for the opera that had been in the making since the mid-1960s and eventually mutated into Le Grand Macabre. Later, Ligeti also shared details about the imaginary land of his childhood, providing glimpses of brightly colored maps of that land and underscoring the importance of his childlike fantasy world. This article explores the dimensions of this “private mythology” and its impact on the composer's creative thinking and work. Its documentary evidence – the description of the land of Kylwiria recorded in 1950 in a booklet of more than 70 pages – is presented in examples and examinated for its particularities. On the one hand, it seems that the pioneering exploration of geographical spaces is transferred as a model to the creative exploration of sound spaces. On the other hand, Ligeti's concept of a fantastic counterworld is to be seen in a literary and cultural-historical context, in which it is to be located somewhere between expedition report, travel guide and utopian design. Such an outline sharpens the meaning of Kylwiria as a cipher for creativity in a characteristic mixture of ratio and fantasy.

The Platinum Metals as Selective Hydrogenation Catalysts
Authors: Wells Peter B. 
Published: February 2024

At the present time the consumption of catalytic materials by industry is increasing rapidly, and the demand is growing for catalysts that are able to promote specific or selective reactions. In practice, however, the formulation of a catalyst for a particular function is frequently empirical, at least in part. We are not yet in the position of being able to design a catalyst “on the drawing-board” for a specific complex operation with any high degree of confidence, although this is a situation which we may reasonably hope to achieve at some time in the future.
Recent research at the University of Hull, most of which is unpublished as yet, has indicated that a considerable rationalisation may soon be possible in the field of the metal-catalysed hydrogenation of multiply unsaturated hydrocarbons and the hydroisomerisation of olefins. It is the purpose of this paper to present a preview of this work and to advance some of its tentative conclusions.

Abstract
The 2020 moment magnitude (Mw) 6.5 Stanley, Idaho, earthquake raised questions about the history and extent of complex faulting in the northwestern Centennial Tectonic Belt (CTB) and its relation to the Sawtooth normal fault and Eocene Trans-Challis fault system (TCFS). To explore faulting in this area, we excavated a paleoseismic trench across the Sawtooth fault along the western margin of the CTB, and compared an early Holocene (9.1 ± 2.1 ka, 1σ) rupture at the site with lacustrine paleoseismic data and fault mapping in the 2020 epicentral region. We find: (1) a history of partial to full rupture of the Sawtooth fault (Mw 6.8–7.4), (2) that shorter ruptures (Mw≤6.9) are likely along distributed and discontinuous faults in the epicentral region, (3) that this complex system that hosted the 2020 earthquake is not directly linked to the Sawtooth fault, (4) that the northeast-trending TCFS likely plays a role in controlling fault length and rupture continuity for adjacent faults, and (5) that parts of the TCFS may facilitate displacement transfer between normal faults that accommodate crustal extension and rotation. Our results help unravel complex faulting in the CTB and imply that relict structures can help inform regional seismic hazard assessments.

Allergic fungal rhinosinusitis (AFRS) is one of the most common form of fungal sinusitis. It is a hypersensitivity reaction to fungal infection. The patients are either atopic or immunocompetent. Such patients suffer from rhinosinusitis. The allergic mass is expanding in nature and this results in bony remodelling. It also involves the adjacent structures. Ophthalmological complications occur when the mass involves orbit. These complications include diplopia, telecanthus, proptosis, malar flattening, epiphora, asthenopia and even visual loss. The diagnosis can be made using radiological imaging. Histopathological examination is needed to confirm the diagnosis. The treatment of AFRS includes both surgical and medical therapy. This case report demonstrates a rare presentation of the non-invasive AFRS with bilateral proptosis with hypertelorism. The patient showed a drastic improvement after endoscopic sinus surgery, oral anti fungal medication, oral steroids and nasal saline irrigation.
individuo social frente a la modernidad: habitus como forma de acción
Authors: Sánchez Carballo Alfredo , Noda Ramírez Eder Jesús 
Published: February 2024

El objetivo de este trabajo está enfocado en una discusión del concepto y la noción de habitus, un mecanismo de acción dinámico frente a la condición de modernidad. El habitus parece algo innato, aunque se forma de esquemas de percepción y valoración de una estructura social. Hace referencia a un proceso de sociabilidad adquirido e incorporado en el cuerpo de forma duradera. Si el habitus tiene capacidad de injerencia y adaptación sobre el individuo además de construir una praxiología social y la sustancialidad de lo relacional como piedra angular de la construcción de la realidad, someterlo a prueba frente a los procesos de la modernidad es parte del ejercicio teórico de este trabajo.
Youth Heavy Metal Bands in Morocco: Resistance and the Struggle for Change
Authors: El Harrami Said , Yachoulti Mohammed 
Published: February 2024

In Morocco, Metal is a controversial genre of youth music that has usually been misinterpreted, marginalized and stigmatized by many individuals due to its transgressive sound, lyrical contents and visual codes. In this regard, the purpose of this paper is to explore the specific lyrical themes of Moroccan Metal bands concerning elements of symbolic transgression and musical activism. It also aims to the main motivations that push these bands to produce and sustain their musical discourse taking into account the conservative nature of the Moroccan context. Using both content analysis and semi-structured interviews, the paper concluded that despite the severe cultural challenges that surround their socio-cultural condition, the artistic participation of Moroccan Metal bands has not just allowed them to gain support from their subculture but also made them impose themselves as leaders of culture of courage. By tracing the Moroccan Metal bands’ artistic engagement and commitments, this paper will bring to light the cultural sociology and multi-dimensional nature of Metal narratives in Morocco and the challenges that shape its existence. It also provides an interesting account for students and academics concerned with cultural minorities, literature and arts-related topics about the nature of content produced by this minority as a reference.
