By combining nonlinear polarization rotation (NPR) and semiconductor saturable absorber, we report a hybrid mode-locked Er:ZBLAN fiber oscillator at 2.8 µm. Stable 325-fs mode-locked pulses with an average power of 131 mW and a record signal-to-noise ratio of 79 dB at the fundamental frequency of 55.4 MHz are generated. Numerical simulations are carried out based on the modified coupled nonlinear Schrödinger equations, and offer new insights into the underlying dynamics of pulse generation. The simulations indicate that compared with Er:ZBLAN fiber lasers mode-locked by NPR alone, the hybrid mode-locked Er:ZBLAN fiber oscillator allows a wider range and a lower threshold of the pump power while maintaining the ultrashort pulse width. Moreover, we numerically demonstrate that the hybrid mode-locked oscillator is less sensitive to the variation of polarization states, which will increase its robustness against environmental disturbance. This is the first time that the hybrid mode-locking technique is applied in the mid-infrared, opening up new opportunities for the development of stable ultrafast mid-infrared laser sources and practical applications outside the laboratory.

Published: January 2023

The design, fabrication, and characterization of a 16-element optical phased array (OPA) using a high index (n = 3.1) silicon-rich silicon nitride (SRN) is demonstrated. We present one-dimensional beam steering with end-fire facet antennas over a wide steering range of >115° at a fixed wavelength of 1525 nm. A beam width of 6.3° has been measured at boresight, consistent with theory. We demonstrate SRN as a viable material choice for chip-scale OPA applications due to its high thermo-optic coefficient, high optical power handling capacity [negligible two-photon absorption (TPA)], wide transparency window, and CMOS compatibility.

Published: January 2023

Quantum key distribution (QKD) is an effective solution to ensure the secure transmission of information. However, for the large-scale application of QKD, the interoperability and flexibility of the transmitter and receiver are urgent issues to be solved. Here, for the first time, to the best of our knowledge, we experimentally verify the feasibility of one continuous-variable (CV) QKD system to achieve multiple protocols and rates. The flexibility of the system comes from the modulator realizing multiple protocols and a broadband coherent detector realizing multiple symbol rates. The results show that this system can switch between different rates and protocols to generate the secure key, and reveal its similarity to classical optical communication. Therefore, It can be adjusted according to user needs and provides a system-level solution for building a flexible quantum network.
NFRHT modulation between graphene/SiC core-shell and hBN plate through strain
Authors: Zhang Kun , Zhang Bo , Song Jinlin , Luo Zixue , Cheng Qiang
Published: January 2023

We numerically investigate the near-field radiative heat transfer (NFRHT) between a graphene/SiC core-shell (GSCS) nanoparticle and a hexagonal boron nitride (hBN) plate. By applying a compressive strain to the hBN plate, its hyperbolic modes can be tuned. Consequently, the hyperbolic phonon polaritons (HPPs) of hBN and the high-frequency localized surface resonance (LSR) of GSCS nanoparticle can couple and decouple, thus allowing for the active control of NFRHT. Furthermore, we predict that, combining with the effect of the chemical potential of graphene shell on NFRHT, a thermal rectification ratio of up to 13.6 can be achieved. This work enriches the phonon-polariton coupling mechanism and also facilitates dynamic thermal management at the nanoscale.

Published: January 2023

We demonstrate a concept for the active manipulation of radiated fields by a magnetoplasmonic half-wave dipole nanoantenna. Our idea comprises a two arms nanoantenna, made of metallic ferromagnetic cobalt–silver alloy (Co6Ag94), inspired by the analogous radio frequency half-wave dipole antenna design. Numerical results, obtained under the magnetization saturation condition, indicate a tilting of the radiated beam depending on the magnitude and sense of the magnetization of the ferromagnetic material. Significantly, we obtained tilting angles as large as

Results in this work not only open up a new, to the best of our knowledge, way to dynamically manipulate the beam steering at the chip-scale, but also contribute to unveil novel magneto-optical effects at the nanoscale.
Secure turbulence-resistant coherent free-space optical communications via chaotic region-optimized probabilistic constellation shaping
Authors: Wu Tingwei , Zeng Wei , Liu Yejun , Song Song , Zhao Lun , Chen Chen , Zhang Chongfu , Guo Lei
Published: January 2023

We propose a chaotic region-optimized probabilistic constellation shaping (CRPCS) scheme to enhance the security and the resistance to turbulence for free-space optical (FSO) communications. For this approach, a four-dimensional hyperchaotic system generates a pseudorandom sequence to rotate and encrypt the constellation. Constellation distribution of short pseudorandom sequences behaves as the law of a non-uniform character. Grouping long pseudorandom sequences and counting the characteristics of constellation distribution can realize probabilistic constellation shaping with low and fixed redundant information. We demonstrate a 56 Gbyte/s coherent FSO communication system based on log-normal and Gamma–Gamma turbulence models with a key space of 1075. The results show that the optical receiver sensitivity is improved by 0.3–1.1 dB, and the transmission distance is also improved by 3.2%–7.0% in different shaping cases.
Soliton transformation between different potential wells
Authors: Wang Qing , Mihalache Dumitru , Belić Milivoj R. , Zeng Liangwei , Lin Ji
Published: January 2023

This paper presents a novel, to the best of our knowledge, method for realizing soliton transformation between different potential wells by gradually manipulating their depths in the propagation direction. The only requirements for such a transformation are that the gradient of the manipulated depth is smooth enough and the solitons in different potential wells are both in the regions of stability. The comparison of transformed solitons with the iterative ones obtained by the accelerated imaginary-time evolution method proves that our method is efficient and reliable. An interesting consequence is that in some complex potential wells in which it is difficult to find solitons by iterative numerical methods, stable solitons can be obtained by the transformation method. The controllable soliton transformation provides an excellent opportunity for all-optical switching, optical information processing, and other applications.

Published: January 2023

We report experimental results on the formation of microvoids in bulk sapphire produced through the single-shot illumination of the sample by near-infrared, simultaneously spatially and temporally focused (SSTF) laser beams. Compared with the cases of tightly focused femtosecond Gaussian and flattop beams, the SSTFs produce internal microvoids with significantly larger volumes and without cracks between the interaction sites, which may be beneficial for applications in volumetric data storage and for the studies of exotic, super-dense elemental phases contained in the densified shells surrounding the microvoids.
Laser-reduced graphene oxide for a flexible liquid sliding sensing surface
Authors: Han Xing-Chen , Wang Qiang , Chen Zhao-Di , Zhou Hao , Cai Qing , Han Dong-Dong
Published: January 2023

Flexible electronic skin is a flexible sensor system that imitates human skin. Recently, flexible sensors have been successfully developed. However, the droplet sliding sensing technology on a flexible electronic skin surface is still challenging. In this Letter, a flexible droplet sliding sensing surface is proposed and fabricated by laser-reduced graphene oxide (LRGO). The LRGO shows porous structures and low surface energy, which are beneficial for infusing lubricants and fabricating stable slippery surfaces. The slippery surface guarantees free sliding of droplets. The droplet sliding sensing mechanism is a combination of triboelectricity and electrostatic induction. After a NaCl droplet slides from lubricant-infused LRGO, a potential difference (∼0.2 mV) can be measured between two Ag electrodes. This study reveals considerable potential applications in intelligent robots and the medical field.

Published: January 2023

Dynamical models in the form of systems of ordinary differential equations have become a standard tool in systems biology. Many parameters of such models are usually unknown and have to be inferred from experimental data. Gradient-based optimization has proven to be effective for parameter estimation. However, computing gradients becomes increasingly costly for larger models, which are required for capturing the complex interactions of multiple biochemical pathways. Adjoint sensitivity analysis has been pivotal for working with such large models, but methods tailored for steady-state data are currently not available. We propose a new adjoint method for computing gradients, which is applicable if the experimental data include steady-state measurements. The method is based on a reformulation of the backward integration problem to a system of linear algebraic equations. The evaluation of the proposed method using real-world problems shows a speedup of total simulation time by a factor of up to 4.4. Our results demonstrate that the proposed approach can achieve a substantial improvement in computation time, in particular for large-scale models, where computational efficiency is critical.
Validation of Sepsis-3 using survival analysis and clinical evaluation of quick SOFA, SIRS, and burn-specific SIRS for sepsis in burn patients with suspected infection
Authors: Yoon Jaechul , Kym Dohern , Hur Jun , Cho Yong Suk , Chun Wook , Yoon Dogeon
Published: January 2023

Purpose

Sepsis-3 is a life-threatening organ dysfunction caused by dysregulated host responses to infection; and defined using the Sepsis-3 criteria, introduced in 2016, however, the criteria need to be validated in specific clinical fields. We investigated mortality prediction and compared the diagnostic performance of quick Sequential Organ Failure Assessment (qSOFA), systemic inflammatory response syndrome (SIRS), and burn-specific SIRS (bSIRS) in burn patients.

Methods

This single-center retrospective cohort study examined burn patients in Seoul, Korea during January 2010–December 2020. Overall, 1,391 patients with suspected infection were divided into four sepsis groups using SOFA, qSOFA, SIRS, and burn-specific SIRS.

Results

Hazard ratios (HRs) of all unadjusted models were statistically significant; however, the HR (0.726, p = 0.0080.001) in the SIRS ≥2 group is below 1. In the adjusted model, HRs of the SOFA ≥2 (2.426, <0.001), qSOFA ≥2 (7.198, p<0.001), and SIRS ≥2 (0.575, p<0.001) groups were significant. The diagnostic performance of dichotomized qSOFA, SIRS, and bSIRS for sepsis was defined by the Sepsis-3 criteria. The mean onset day was 4.13±2.97 according to Sepsis-3. The sensitivity of SIRS (0.989, 95% confidence interval [CI]: 0.982–0.994) was higher than that of qSOFA (0.841, 95% CI: 0.819–0.861) and bSIRS (0.803, 95% CI: 0.779–0.825). Specificities of qSOFA (0.929, 95% CI: 0.876–0.964) and bSIRS (0.922, 95% CI: 0.868–0.959) were higher than those of SIRS (0.461, 95% CI: 0.381–0.543).

Conclusion

Sepsis-3 is a good alternative diagnostic tool because it reflects sepsis severity without delaying diagnosis. SIRS showed higher sensitivity than qSOFA and bSIRS and may therefore more adequately diagnose sepsis.
Statistical and machine learning approaches to predict the necessity for computed tomography in children with mild traumatic brain injury
Authors: Miyagawa Tadashi , Saga Marina , Sasaki Minami , Shimizu Miyuki , Yamaura Akira
Published: January 2023

Background

Minor head trauma in children is a common reason for emergency department visits, but the risk of traumatic brain injury (TBI) in those children is very low. Therefore, physicians should consider the indication for computed tomography (CT) to avoid unnecessary radiation exposure to children. The purpose of this study was to statistically assess the differences between control and mild TBI (mTBI). In addition, we also investigate the feasibility of machine learning (ML) to predict the necessity of CT scans in children with mTBI.

Methods and findings

The study enrolled 1100 children under the age of 2 years to assess pre-verbal children. Other inclusion and exclusion criteria were per the PECARN study. Data such as demographics, injury details, medical history, and neurological assessment were used for statistical evaluation and creation of the ML algorithm. The number of children with clinically important TBI (ciTBI), mTBI on CT, and controls was 28, 30, and 1042, respectively. Statistical significance between the control group and clinically significant TBI requiring hospitalization (csTBI: ciTBI+mTBI on CT) was demonstrated for all nonparametric predictors except severity of the injury mechanism. The comparison between the three groups also showed significance for all predictors (p<0.05). This study showed that supervised ML for predicting the need for CT scan can be generated with 95% accuracy. It also revealed the significance of each predictor in the decision tree, especially the "days of life."

Conclusions

These results confirm the role and importance of each of the predictors mentioned in the PECARN study and show that ML could discriminate between children with csTBI and the control group.

The SARS-CoV-2 virus is currently causing a global pandemic. Infection may result in a systemic disease called COVID-19, affecting primarily the respiratory tract. Often the gastrointestinal tract and kidneys also become involved. Angiotensin converting enzyme 2 (ACE2) serves as the receptor for SARS-CoV-2. The membrane proteins, Transmembrane serine protease 2 (TMPRSS2) and Neuropilin 1 (NRP1) are accessory proteins facilitating the virus entry. In this study we show that the human proximal kidney tubules, express these factors. We hypothesized that cancers derived from proximal tubules as clear cell (CCRCC) and papillary renal cell carcinoma (PRCC), retain the expression of the SARS-CoV-2 entry factors making these cancers susceptible to SARS-CoV-2 infection. We used bioinformatics, western blotting, and assessment of tissue micro arrays (TMA) including 263 cases of CCRCC, 139 cases of PRCC and 18 cases of chromophobe RCC to demonstrate that the majority of CCRCC and PRCC cases retained the RNA and protein expression of the entry factors for SARS-CoV-2. We furthermore show that SARS-CoV-2 virus propagated robustly in primary cultures of CCRCC and PRCC cells with a visible virus cytopathogenic effect correlating with viral RNA expression levels. We also noted that the delta-variant of SARS-CoV-2 causes cancer cells to form syncytia in-vitro. This phenomenon was also identified histologically in CCRCC tissue from a patient that had been hospitalized for COVID-19, twelve months prior to nephrectomy. Our data provide insights into SARS-CoV-2 infectivity in renal cell carcinoma and that the virus causes a distinct cytopathogenic effect.
Suitability and user acceptance of the eResearch system “Prospective Monitoring and Management App (PIA)”—The example of an epidemiological study on infectious diseases

Published: January 2023

Background

The eResearch system “Prospective Monitoring and Management App (PIA)” allows researchers to implement questionnaires on any topic and to manage biosamples. Currently, we use PIA in the longitudinal study ZIFCO (Integrated DZIF Infection Cohort within the German National Cohort) in Hannover (Germany) to investigate e.g. associations of risk factors and infectious diseases. Our aim was to assess user acceptance and compliance to determine suitability of PIA for epidemiological research on transient infectious diseases.

Methods

ZIFCO participants used PIA to answer weekly questionnaires on health status and report spontaneous onset of symptoms. In case of symptoms of a respiratory infection, the app requested participants to self-sample a nasal swab for viral analysis. To assess user acceptance, we implemented the System Usability Scale (SUS) and fitted a linear regression model on the resulting score. For investigation of compliance with submitting the weekly health questionnaires, we used a logistic regression model with binomial response.

Results

We analyzed data of 313 participants (median age 52.5 years, 52.4% women). An average SUS of 72.0 reveals good acceptance of PIA. Participants with a higher technology readiness score at the beginning of study participation also reported higher user acceptance. Overall compliance with submitting the weekly health questionnaires showed a median of 55.7%. Being female, of younger age and being enrolled for a longer time decreased the odds to respond. However, women over 60 had a higher chance to respond than women under 60, while men under 40 had the highest chance to respond. Compliance with nasal swab self-sampling was 77.2%.

Discussion

Our findings show that PIA is suitable for the use in epidemiologic studies with regular short questionnaires. Still, we will focus on user engagement and gamification for the further development of PIA to help incentivize regular and long-term participation.
Game bird carcasses are less persistent than raptor carcasses, but can predict raptor persistence dynamics

Published: January 2023

Researchers conduct post-construction fatality monitoring (PCFM) to determine a wind energy facility’s direct impacts on wildlife. Results of PCFM can be used to evaluate compliance with permitted take, potentially triggering adaptive management measures or offsetting mitigation; reducing uncertainty in fatality rates benefits wind companies, wildlife agencies, and other stakeholders. As part of PCFM, investigators conduct carcass persistence trials to account for imperfect detection during carcass surveys. In most PCFM studies, pen-raised game birds and other non-raptor surrogates have been used to estimate persistence of all large birds, including raptors. However, there is a growing body of evidence showing carcass persistence varies by bird type; raptor fatality estimates based on game bird carcass persistence may therefore be biased high. We conducted raptor and game bird carcass persistence field trials for 1 year at 6 wind energy facilities. Raptor carcass persistence varied by habitat and season, whereas the best-supported game bird model only included habitat. Raptor persistence probabilities were higher than corresponding game bird persistence probabilities for 13 of the 16 habitat and season combinations. Analysis of a curated large bird persistence meta-dataset showed that raptor carcass persistence varied by season, habitat, and region. The probability of persisting through a 30-day search interval ranged from 0.44 to 0.99 for raptors and from 0.16 to 0.79 for game birds. Raptor persistence was significantly higher than game bird persistence for 95% of the sampled strata. We used these carcass persistence estimates to develop linear mixed-effects models that predict raptor persistence probabilities based on estimated game bird persistence probabilities. Our scaling model provides an important statistical method to address gaps in raptor persistence data at sites in a broad range of landscape contexts in the continental United States and should be used to inform fatality estimation when site-specific raptor persistence data are limited or absent.
Ironía y refutación: el elenchos de Calicles en el Gorgias de Platón
Authors: Forciniti Martín
Published: January 2023

En este trabajo tomo como eje el concepto de ironía para analizar el elenchos que Sócrates practica sobre las opiniones de Calicles en el diálogo Gorgias. Asumo como punto de partida que Sócrates aspira a que su interlocutor modifique su disposición anímica y adopte un modo de vida filosófico, abandonando el retórico. Para ello, desarrolla un elenchos irónico que posee tres momentos: una fingida aceptación por parte de Sócrates de la dicotomía presentada por Calicles entre la vida del político, digna de imitación, y la del filósofo, merecedora de reproche; una inversión de dicha dicotomía; y finalmente una puesta en cuestión de dicha inversión. Concluiré sosteniendo que este tercer momento constituye una nueva maniobra socrática para instar a Calicles a que suspenda sus actividades políticas y examine previamente con él, de manera filosófica, el camino para volverse virtuoso.
La influencia de la negación anaxagórica de la génesis en la física aristotélica
Authors: Díaz María Elena
Published: January 2023

Este trabajo ahonda en una de las estrategias básicas de Aristóteles en Physica I, la homogeneización de conceptos dispares de los primeros físicos, como parte del armado de su taxonomía de posiciones acerca de los principios. Esta estrategia propedéutica de la refutación consiste en el armado de una progresión y una genealogía de las posiciones de los físicos a partir del eleatismo. El objetivo principal de este trabajo es mostrar el sentido específico del concepto de separación en la física de Anaxágoras y las transformaciones que experimenta en la crítica aristotélica. En línea con trabajos recientes como los de Curd (2019) y Marmodoro (2017) que han llamado la atención sobre la especificidad del vocabulario físico de Anaxágoras, esta investigación muestra que las bases de su negación de la génesis y su reelaboración en términos de separación y mezcla reposan sobre tesis originales de su propia física. Tanto a nivel terminológico como conceptual, las nociones de separación y mezcla anaxagóricas no se pueden exportar a otra teoría física.

El presente trabajo toma como punto de partida el contexto de la Metafísica en el que Aristóteles cita el fr. 28B 16 DK de Parménides, el cual es analizado a la luz de otros pasajes paralelos dentro del Corpus Aristotelicum, así como de la confrontación con el comentario que Teofrasto hace de ese mismo fragmento parmenídeo en el De Sensibus, con la finalidad de presentar, con base en un exhaustivo examen léxico y semántico, una reconstrucción de la interpretación que el Estagirita dio a los planteamientos parmenídeos relativos a ciertas funciones psíquicas (percepción sensorial y/o cognición). En consonancia con este análisis, hemos intentado también hacer una valoración acerca de la objetividad de la crítica de Aristóteles hacia los planteamientos filosóficos vertidos en el poema de Parménides.
Deliberação coletiva nas Suplicantes de Eurípides
Authors: Werner Christian
Published: January 2023

Em Suplicantes, uma das mais políticas tragédias de Eurípides, é produzida uma aproximação surpreendente entre o mundo do mito e o do espectador. Embora Teseu, seu protagonista, seja representado como um “rei democrático”, nela não está presente uma cena que possa ser equiparada à experiência da mais típica instituição da democracia ateniense, a deliberação coletiva definidora da assembleia aberta a todos os cidadãos. Todavia, em diferentes momentos do primeiro episódio, chega-se bastante perto. Assim, o objetivo deste texto é discutir como essa tragédia representa formas de deliberação e consenso, para o que se investiga os meandros de dois cenários que levam a uma política de guerra de ataque desenvolvidos no drama, um em Argos, outro, em Atenas.

Published: January 2023

This article details the search for books from the Jewish Religious Community Library in Prague that were looted by the Nazis, and how the institution’s curators are working today to rebuild their original collection. It traces the history of the Prague Library, the Nazis’ policies of confiscating Jewish books for their proposed institutes on the ‘Jewish Question,’ and how some of these confiscated books ended up in the UCLA Library. Librarians at UCLA did not find any professional guidelines for the repatriating looted material from academic libraries, even though the museum and art worlds have dealt with these issues for decades. We share processes we developed and our quest to publicize this issue as broadly as possible. We also discuss methods that European librarians are currently using research provenance. Ours is a singular case, and institutions must understand that each question of repatriation must be considered within its own particular context. We offer some models for addressing repatriation questions and call for an organized English language forum where Judaica librarians in academic libraries and archives everywhere can discuss these issues in order to promote broader understanding, collaboration, and actions.

INTRODUCTION:

For the treatment of spontaneous bacterial peritonitis (SBP), cefotaxime, ceftriaxone, and ciprofloxacin were used as first-line agents. However, considering the increasing rate of antibiotic resistance, it is unclear which of these drugs can be initially recommended. This study aimed to compare the current efficacy of the 3 antibiotics, namely cefotaxime, ceftriaxone, and ciprofloxacin, for the treatment of SBP in patients with cirrhosis with ascites, when guided by therapeutic responses.

METHODS:

This study was a multicenter, prospective, randomized controlled trial. The inclusion criteria were 16- to 75-year-old patients with liver cirrhosis with ascites, having polymorphonuclear cell count of >250/mm3. We performed a follow-up paracentesis at 48 hours to decide continuing or changing the assigned antibiotics and then assessed the resolution rates at 120 and 168 hours of treatment.

RESULTS:

A total of 261 patients with cirrhosis who developed SBP were enrolled. Most of the patients were diagnosed as those with SBP within 48 hours of admission. The resolution rates at 120 hours, which is the primary endpoint, were 67.8%, 77.0%, and 73.6% in the cefotaxime, ceftriaxone, and ciprofloxacin groups, respectively (P = 0.388), by intension-to-treat analysis. The 1-month mortality was similar among the groups (P = 0.770). The model for end-stage liver disease score and the SBP resolution were significant factors for survival.

CONCLUSION:

The efficacy of empirical antibiotics, such as cefotaxime, ceftriaxone, and ciprofloxacin, against SBP was not significantly different. In addition, these antibiotics administered based on response-guided therapy were still efficacious as initial treatment for SBP, especially in those with community-acquired infections.

Authors: Zieliński Cezary
Published: January 2023

In order to assess the impact of robots on society, it is necessary to carefully analyze the state-of-the-art, and in particular the fundamental issues that have yet to be resolved, however having significant impact on the potential societal changes resulting from the development of robotics. The aforementioned impact depends on the level of intelligence of robots, so this aspect dominates in the presented analysis. The presentation has been divided into three parts: 1) analysis of technical factors affecting the intelligence and security of robots, 2) analysis of current capabilities of robots, 3) analysis of diverse predictions of how robotics will evolve, and thus the attitudes towards the influence of the result of this development on society. This part of the paper is devoted to the first of the above mentioned three issues.

O objetivo desta pesquisa é analisar a variação entre os termos tabus prostituta/puta e rapariga, descrevendo qual dos termos concorrentes é mais frequente na amostra analisada e quais variáveis linguísticas (recurso linguístico e nº de variantes usadas) e extralinguísticas (sexo, faixa etária, e localidade) favorecem ou inibem a aplicação da regra variável, a partir dos resultados estatísticos oferecidos pelo GoldVarb X. Constatamos que a variante prostituta/puta é a mais frequente, com 62,5%, em comparação com rapariga, com 37,5%, no entanto, 91,4% dos entrevistados usam o recurso linguístico para eufemizar sua fala. Além disso, o programa não apresentou grupos de fatores favorecedores ou inibidores da regra variável.

As one of the largest digital service providers in the world, YouTube certainly makes breakthroughs to maintain user interest in accessing videos through YouTube, one of which is by creating the YouTube Premium service. This research was conducted to determine the extent to which these services can provide a sense of satisfaction for its users, because as a digital service provider company, YouTube is very dependent on user satisfaction. User satisfaction is influenced by service quality and brand image. In this study, service quality, brand image, and service user satisfaction act as latent variables. To test the predictive relationship between indicator variables and variables that cannot be measured directly (latent variables) by seeing whether there is a relationship or influence between these variables using the obtained modeling can be done using the Partial Least Square method. Therefore, to determine the effect of service quality and brand image on YouTube Premium user satisfaction, an analysis was conducted using the Partial Least Square method. The research data was obtained by distributing questionnaires to 150 YouTube Premium users in Indonesia. The results of the analysis show that service quality and brand image have a significant effect on YouTube Premium user satisfaction.

The livestock sub-sector is one of the sub-sectors that contribute to the national economy and can significantly absorb labour so that it can be relied upon in efforts to improve the national economy. One of the steps used to increase livestock production in each region in Central Java Province is regional mapping. Cluster analysis is one of the regional mapping methods that can increase livestock production by grouping regencies/cities with characteristics of the same level of livestock production based on the type of livestock production. The k-error and k-medoids method is a non-hierarchical cluster analysis method, where the k-error is a method developed to overcome the problem of data measurement errors in classical cluster analysis, while the k-medoids is a method used to overcome the problem of outliers contained in the data. The validity test of the standard deviation ratio and the WB Index was used to determine the quality of the clustering results. The small validity value of the standard deviation ratio and the WB Index shows the best results of clustering and selecting method. Based on the results of the clustering, the optimal cluster was obtained at k=7 using the k-medoids algorithm, where the validation value of the standard deviation ratio=0.773 and WB Index=0.531.

The k-medoids algorithm is a partition-based clustering algorithm that groups n objects as much as k clusters. The algorithm uses medoids as the center point (partition) of the cluster. Medoids are actual objects that are randomly selected as the most centered object in a cluster so that the k-medoids algorithm is robust against outliers. Grouping objects in cluster analysis based on similarities between objects. Measurement of similarity between objects can use the euclidean and manhattan distances. The use of distance in cluster analysis can affect cluster results. Validation of cluster results using internal validation, namely the silhouette index. The Weighted-Length Recency Frequency Monetary (W-LRFM) model is a model that applies the relative importance (weight) of the LRFM model according to the importance of each variable in the LRFM model. LRFM model is a model used for customer segmentation based on customer behavior which consists of variables length, recency, frequency, and monetary. The relative importance (weight) of the W-LFRM model uses the Analytics Hierarchical Process (AHP) method. The W-LRFM model is used to calculate the Customer Lifetime Value (CLV) of each cluster. The implementation of k-medoids and the W-LFRM model in this study are used for customer segmentation based on the length, recency frequency, and monetary variable. The formation of these variables is the result of transformation of customer behavior data such as transaction id, date of purchase, and a total amount of 41,073 rows into variable length, recency, frequency, and monetary as much as 5,108 rows. The criteria of the best cluster formed are k = 2 using the manhattan distance with the average of coefficient values = 0.62. The weights on the W-LRFM model produced based on the AHP method are 0.16, 0.29, 0.47, and 0.08 for the variable length, recency, frequency, and monetary. CLV formed from two clusters, namely 0.158 and 0.499. CLV in the second cluster is bigger so that the second cluster becomes the main priority in the marketing strategy. The second cluster has the characteristics 0.29, 0.47, and 0.08 for the variable length, recency, frequency, and monetary. The second cluster has the characteristics  means a loyal customer group. The first cluster has characteristics  means a potential customer group. This research is assisted by using Graphical User Interface (GUI) R to facilitate analysis

The pharmaceutical sector has become a concern during the Covid-19 pandemic because of the large use of drugs. Companies need to improve financial performance to increase their share prices and investors need analysis to predict future stock prices. This study aims to analyze the influence of stock prices on 10 pharmaceutical companies on the Indonesia Stock Exchange during the third quarter of 2020 to the third quarter of 2021. Based on previous research, the factors that are thought to have an effect on changes in stock prices are internal financial ratios (ROA, ROE, NPM, GPM, EPS, PER, BV, PBV, DAR, DER, CR, QR, Cash Asset Ratio) and external inflation, exchange rates, interest rates. The method used in this research is dynamic panel factor regression analysis with GMM (Generalized Method of Moment) estimation. Factor analysis to reduce the independent variables to form a factor score which is then entered into the regression. The regression model was obtained from the comparison of Arellano-Bond GMM and Blundell-Bond System. The GMM system is the development of Arellano-Bond which will produce more efficient estimates when the sample time series is short. The results of the study were obtained 3 factor scores with a total variance of 81.757% from the elimination of 6 variables that had MSA <0.5. The best model is the Blundell-Bond Twostep System which fulfills the model assumptions with RMSE 803.276.
