Upconversion-Assisted Dual-Band Luminescent Solar Concentrator Coupled for High Power Conversion Efficiency Photovoltaic Systems

A luminescent solar concentrator (LSC)-based photovoltaic (PV) system, consisting of an LSC panel that harvests light and an edge-mounted solar cell that produces electricity using the photoluminescent light, is promising for semitransparent building-integrated photovoltaics (BIPVs). Here, we demonstrate a highly efficient and highly semitransparent LSC-PVs capable of harvesting dual wavelength bands. We used a triplet–triplet annihilation-based photon upconversion (UC) LSC that luminesce high energy green light by absorbing low energy red light, as well as downshift LSC that luminesce green light by absorbing ultraviolet light. The luminescent light concentrated from the two LSCs is absorbed by a dye-sensitized solar cell (DSSC) having a high extinction coefficient at this wavelength. Our optimized dual band LSC-PV exhibited 27% higher power conversion efficiency than the LSC-PV that absorb a single wavelength band. With respect to practical applications, the dual band LSC-DSSCs were fabricated in the fo.
Native-Valve Aspergillus Endocarditis: Case Report and Literature Review

Aspergillus endocarditis represents the second etiological cause of prosthetic endocarditis following Candida spp. On the other hand, native-valve endocarditis due to Aspergillus are anecdotally reported with increasing numbers in the last decade due to new diagnostic technologies such as polymerase chain reaction (PCR) on samples like valve tissue or entire blood. We performed a review of the literature presenting one case report observed at Pisa University Hospital. Seventy-four case reports have been included in a period between 1950–2022. Immunocompromised status (patients with solid tumor/oncohematological cancer or transplanted patients) was confirmed to be the main risk factor for this rare opportunistic infection with a high rate of metastatic infection (above all, central nervous system) and mortality. Diagnosis relies on serum galactomannan and culture with PCR on valve tissue or whole blood. Cardiac surgery was revealed to be a life-saving priority as well as appropriate antifungal therapy including b-liposomal amphotericin or new triazoles (isavuconazole). The endocarditis team, facing negative blood culture endocarditis affecting an immunocompromised patient, should investigate this difficult-to-treat pathogen.
Reliable and Energy-Efficient IoT Systems: Design Considerations in Coexistence Deployments

Currently, there is a plethora of low-power wide-area IoT networking solutions available, each targeting a specific niche of use-cases and deployment scenarios. Existing studies on reliability evaluations of IoT solutions rely on the assumption that a single technology is deployed in the service area, or different IoT technologies operate over dedicated spectrum bands. Here, we investigate the reliability performance of IoT communications in coexisting scenarios, where multiple competing radio-access technologies share spectrum resources. Our focus is on solutions exploiting grant-free communications, which are gaining traction due to their potential to lower the energy consumption, and have been adopted in recent IoT technologies like SigFox and LoRa. We first derive an analytical model of the interference, comprising both inter- and intra-technology interference sources. We then leverage the Poisson Cluster Process for modeling distribution of devices in the service area, and derive expressions for the communication reliability, energy consumption, and battery lifetime of IoT devices. Exploiting these expressions, we study the energy-reliability trade-offs and investigate strategies to maintain or improve communication reliability, while minimizing energy consumption in coexisting scenarios by proper adjustment of communications parameters at the device side and provisioning resources at the network side. We verify the analytical results via numerical evaluations, confirming their accuracy and performing optimization in some example networking setups.
Analysis of the Influence of Digital Banks on Bank Profitability

This article aims to present an analysis of the influence of digital banks on bank profitability in Indonesia in 2013–2021. The research method used is a comparative causal method with secondary data from annual reports of sample banks taken purposively from banks in Indonesia that have provided digital bank transaction services and have gone public from 2013–2021. The results show that the number of digital bank transactions in the form of mobile banking (MB) has a positive effect on bank profitability by controlling liquidity (LDR). This happens because MB transactions are emergency and simple with smaller transaction limits so that the number of MB transactions is large and in line with increasing operational efficiency and bank profitability, and the number of digital bank transactions in the form of Internet banking does not affect bank profitability even though it has controlled liquidity (LDR). ). This is because IB transactions are complex with a nominal limit per transaction that is larger than MB, so the number of IB transactions is smaller than the number of MB transactions. Keywords: Digital Bank; Mobile Banking; Internet Banking; Liquidity; Profitability Abstrak Artikel ini bertujuan menyajikan analisis pengaruh dari bank digital terhadap profitabilitas bank di Indonesia pada tahun 2013–2021. Metode penelitian yang digunakan adalah metode kausal komparatif dengan data sekunder dari laporan tahunan bank sampel yang diambil secara purposive pada bank di Indonesia yang telah memberikan layanan transaksi bank digital dan telah go public dari tahun 2013–2021. Hasil penelitian menunjukkan jumlah transaksi bank digital berupa mobile-banking (MB) berpengaruh positif terhadap profitabilitas bank dengan mengontrol likuiditas (LDR). Hal ini terjadi karena transaksi MB bersifat darurat dan simpel dengan limit pertransaksi yang lebih kecil sehingga jumlah transaksi MB banyak dan selaras dengan peningkatan efisiensi operasional dan profitabilitas bank, dan jumlah transaksi bank digital berupa internet banking tidak berpengaruh terhadap profitabilitas bank walaupun sudah mengontrol likuiditas (LDR). Hal ini karena transaksi IB bersifat kompleks dengan limit nominal pertransaksi yang lebih besar dari MB, sehingga jumlah transaksi IB lebih kecil dari jumlah transaksi MB.

An MM algorithm for estimation of a two component semiparametric density mixture with a known component

: We consider a semiparametric mixture of two univariate den- sity functions where one of them is known while the weight and the other function are unknown. We do not assume any additional structure on the unknown density function. For this mixture model, we derive a new suﬃcient identiﬁability condition and pinpoint a speciﬁc class of distributions describing the unknown component for which this condition is mostly sat-isﬁed. We also suggest a novel approach to estimation of this model that is based on an idea of applying a maximum smoothed likelihood to what would otherwise have been an ill-posed problem. We introduce an iterative MM (Majorization-Minimization) algorithm that estimates all of the model parameters. We establish that the algorithm possesses a descent property with respect to a log-likelihood objective functional and prove that the algorithm, indeed, converges. Finally, we also illustrate the performance of our algorithm in a simulation study and apply it to a real dataset.
An optimal iterative solver for symmetric indefinite linearsystems with PDE origins: Balanced black-box stopping tests

This work discusses the design of efficient algorithms for solving symmetric indefinite linear systems arising from FEM approximation of PDEs. The distinctive feature of the preconditioned MINRES solver that is used here is the incorporation of error control in the ‘natural norm’ in combination with an effective a posteriori estimator for the PDE approximation error. This leads to a robust and optimal blackbox stopping criterion: the iteration is terminated as soon as the algebraic error is insignificant compared to the approximation error.

Effect of Drilling Parameters and Tool Geometry on the Thrust Force and Surface Roughness of Aerospace Grade Laminate Composites

Carbon fiber-reinforced plastics (CFRPs) have been specially developed to enhance the performance of commercial and military aircraft because of their strength, high stiffness-to-density ratios, and superior physical properties. On the other hand, fasteners and joints of CFRP materials may be weak due to occurring surface roughness and delamination problems during drilling operations. This study’s aim is to investigate the drilling characterization of CFRPs with different drilling parameters and cutting tools. Drilling tests were performed with the Taguchi orthogonal array design (L18: 2^1 3^3). Tests were conducted with three levels of cutting speed (15, 30, 45 m/min), three levels of feed rate (0.05, 0.1, 0.2 mm/rev), two levels of drill diameter (3 and 5 mm), and three different types of drills (two twist drills with a point angle of 138° and 120° and one brad drill). Thrust forces were recorded during drilling tests, and afterwards surface roughness and hole delamination were measured. Obtained results were analyzed with Taguchi and two-way ANOVA. The general tendency was that low cutting speed, high feed rate, and small diameter drill caused an increase in thrust force. Surface roughness decreases with increasing tool diameter, decreasing feed, and cutting speed. Delamination factors of the samples dropped depending on decreasing thrust force levels. Remarkably, it is possible to control the delamination factor values via better surface quality. The brad drill and larger point angle have a negative effect on the drilling quality of CFRPs. According to all results, the cutting speed of 45 m/min and feed rate of 0.05 mm/rev using a type II drill having a 120° point angle and 5 mm diameter (12th trial) and the cutting speed of 30 m/min and feed rate of 0.05 mm/rev using a type II drill having a 120° point angle and 3 mm diameter (2nd trial) were determined as optimum drilling conditions.
Systematic Literature Review of the Epidemiological Characteristics of Pneumococcal Disease Caused by the Additional Serotypes Covered by the 20-Valent Pneumococcal Conjugate Vaccine

Higher valency pneumococcal conjugate vaccines (PCV15 and PCV20) have been developed to address the disease burden of current non-vaccine serotypes. This review describes the epidemiological characteristics of serotypes beyond PCV13 (serotypes 8, 10A, 11A, 12F, 15B/C, 22F, and 33F; PCV20nonPCV13 serotypes). Peer-reviewed studies published between 1 January 2010 (the year PCV13 became available) and 18 August 2020 were systematically reviewed (PROSPERO number: CRD42021212875). Data describing serotype-specific outcomes on disease proportions, incidence, severity, and antimicrobial non-susceptibility were summarized for individual and aggregate PCV20nonPCV13 serotypes by age group and by type and duration of pediatric PCV immunization program. Of 1168 studies, 127 (11%) were included in the analysis. PCV20nonPCV13 serotypes accounted for 28% of invasive pneumococcal disease (IPD), although the most frequent serotypes differed between children (10A, 15B/C) and adults (8, 12F, 22F). In children, serotype 15B/C tended to be more frequently associated with pneumococcal meningitis and acute otitis media; in adults, serotype 8 was more frequently associated with pneumonia and serotype 12F with meningitis. Serotypes 10A and 15B/C in children and 11A and 15B/C in adults were often associated with severe IPD. Serotype 15B/C was also among the most frequently identified penicillin/macrolide non-susceptible PCV20nonPCV13 serotypes. These results could inform decision making about higher valency PCV choice and use.
Molecular Characterization and Immunological Approaches Associated with Yellow Grub Trematode (Clinostomid) Infecting Nile Tilapia

Yellow grub disease is caused by clinostomid metacercariae (CM) infecting freshwater fish and has a potential impact on human health by causing Halzoun disease. This study aimed to combine both molecular and immunological approaches to characterize CM naturally infecting Nile tilapia. Two hundred and fifty Nile tilapia, Oreochromis niloticus, were collected from Giza Governorate and screened for the presence of CM. Samples were collected from buccal cavities and blood of 20 highly infected fish (≥10 cysts/fish) under aseptic conditions. Partial sequencing of the ITS rRNA region was performed to identify and distinguish the causative agents from closely related species. The cellular immune response between infected and noninfected O. niloticus was investigated by quantitative real-time-PCR targeting tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Results showed significant increases in the levels of both TNF-α and IL-1β ( p < 0.01 ) in fish infected with Clinostomum phalacrocoracis when compared to those infected with Clinstomum complanatum and negative controls (3.6 ± 0.2). Furthermore, the assessment of the levels of lysozyme activity in infected fish sera showed high levels versus noninfected ones.
Percutaneous nephrolithotomy in supine position with less than 24-hour hospital stay; a single-center experience

ABSTRACT Objectives To report our initial experience of day care percutaneous nephrolithotomy (PCNL) with early hospital discharge within less than 24 hours of the procedure. Patients and Methods The files of patients treated with PCNL between 1st January 2020 till 31st December 2022 were retrospectively reviewed. Day care PCNL was defined as the discharge of patients either on the same day or within 24 hours after surgery. Patient age, ASA score, body mass index, stone diameter, laterality, stone burden, Hounsfield unit, and Guy’s score were analyzed. Operative time, size of the access tract, method of lithotripsy, estimated blood loss, and length of hospital stay were also recorded. Postoperative complications were stratified according to the Dindo-Clavien classification. The primary outcome was to evaluate the feasibility and safety of early discharge within 24 hours after PCNL compared to the in-patients who were kept in hospital for at least 2 days after surgery. Results A total of 85 patients underwent PCNL at our center of whom 36 patients were discharged within 24 hours (day care PCNL) of the procedure and 49 patients were kept for at least 2 days (in-patient PCNL). In the day care group, median stone burden was 465 mm2 (360-980) and 18 patients (50%) had Guy’s stone score ≥ III. The median tract size was 24 (13-30) and endoscopic combined intrarenal surgery (ECIRS) was performed in 7 cases in the day care group. Tubeless PCNL was carried out in 88.8% of the day care surgery group compared to 37.5% in the in-patient group (p < 0.0001). The postoperative complication rate was comparable between both groups (13.8% vs 22.4% for day care vs in-patient group, respectively, p = 0.08). Conclusions Day care PCNL is feasible and safe for selected patients including those having large stone burden without increasing the risk of complications or readmission rate.
Bound by history, culture, religion and kinship

ABSTRACT Most studies of Indonesia-Malaysia relations focus on conflict. This study analyses the depictions of Malaya in a renowned bi-weekly Islamic magazine in Indonesia in 1960, Pandji Masjarakat. The findings indicate that the magazine constructed positive perceptions of Malaya and encouraged its readers to adopt them. It promoted an understanding that Indonesia and Malaya had a long common history, and in the past were tied by religious, kinship and cultural bonds. It emphasised that Islam played an important role as a unifying factor among regions in the Malay world before the colonial era. It saw Malay culture, especially the Malay language, as a shared legacy of both countries that had been marginalised by European colonialism. The magazine motivated linguists and people from both countries to rejuvenate the language for modern use. Of no less importance was the key actor in the magazine’s constructive approach to Malaya, its chief editor, Hamka, who was personally connected to the Malay world. This research sheds light on the Indonesian press’ attempts to promote similarities and cooperation rather than differences and dispute between the two countries in the context of postcolonial Southeast Asia.
Exploring the impact of childhood maltreatment and BPD on impulsivity in crimes of passion

Background Crimes of passion, characterized as unpremeditated impulsive aggression, have garnered increasing attention in recent years. Impulsivity, a major factor in crimes of passion, is also a common feature of various health conditions, including Borderline Personality Disorder (BPD). Childhood maltreatment is considered a significant precursor to BPD and is closely related to impulsivity. Although prior research has affirmed the relationship between impulsivity, childhood maltreatment, BPD, and criminal behavior, few studies have examined these variables’ interconnections within the context of crimes of passion. This study seeks to explore the relationship between childhood maltreatment, BPD, and impulsivity in crimes of passion, assessing the former’s impact on the latter. Method Our research examined 133 crimes of passion offenders and 149 other offenders from the Shenzhen male prison in China. All 282 participants completed The Abbreviated Version of The Barratt Impulsiveness Scale (ABIS), The UPPS Impulsivity Scale (Urgency, Premeditation, Perseverance, Sensation Seeking), The McLean Screening Instrument for Borderline Personality Disorder (MSI-BPD), and The Childhood Trauma Questionnaire (CTQ). Results Our findings indicated that (1) crimes of passion offenders scored significantly higher in emotional neglect, physical neglect, and overall childhood maltreatment than did other offenders, and childhood maltreatment scores were notably higher in the high BPD trait group. (2) Crimes of passion offenders demonstrated significantly elevated impulsivity in attention and nonplanning scales compared to other offenders. Impulsivity scores across all scales were also significantly higher in the high BPD trait group. (3) Emotional neglect was found to significantly influence the urgency scale in crimes of passion offenders. An interaction effect was noted between physical abuse and high BPD traits, leading to increased impulsivity in crimes of passion offenders. Conclusion This study underscores the predictive roles of childhood maltreatment and BPD in determining impulsivity within the context of crimes of passion.
ICT and the UN’s Sustainable Development Goal for Education: Using ICT to Boost the Math Performance of Immigrant Youths in the US

In the context of the United Nations’ Sustainable Development Goal for education, this study examines the potential of information, communication, and technology (ICT) as a way to provide quality education for all, with a focus on immigrant youth in the United States. The study uses structural equation models (SEM) to analyze data from a nationally representative data set, Trends in International Mathematics and Science Study (TIMSS)-USA. Focusing on mathematics achievement among immigrant youth (with non-immigrant youth as a reference group), this study explores the effects of ICT access and two types of ICT use for educational purposes: generic and specific. The results indicate that ICT access and specific ICT use both have positive direct, indirect, and total effects on math performance for immigrant youths, while generic ICT use has only a nonsignificant negative effect. In nonimmigrant youths, these ICT variables showed a different pattern, with the effects of ICT access and specific ICT use being less pronounced, but generic ICT use exhibiting a significant negative effect. These findings show the potential role of ICT-mediated education in narrowing the achievement gap between immigrant and nonimmigrant students, thereby helping immigrants better integrate into their destination countries.
Frequency and risk factors for Hepatitis C virus seropositivity in blood transfusion-dependent thalassemic patients in Qena hospitals

Background: Beta-thalassemia major (BTM) is still mostly treated with routine blood transfusions. One of the most prevalent transfusion-transmitted infections (TTI) of clinical significance is the hepatitis C virus (HCV). Objectives: To estimate the prevalence of HCV infection among thalassemic patients in Qena hospitals, and to identify the possible risk factors associated with HCV infection. Patients and methods: a cross-sectional study involving 400 thalassemic patients with an age ranging from 1.5 to 29 years, a mean age of 12.8 ±7.3 years, 176 (44%) were male and 224 (56%) were female, and 75.5% were from rural areas. All are reviewed by a structured questionnaire . Results: The study revealed that the prevalence of HCV infection in the studied thalassemic patients was 9.5%. The most important risk factors were the duration of blood transfusion for more than 15 years, previous surgery, dental procedure, and splenectomy (P<0.001), followed by patient age of more than 18 years (P = 0.001), urban population, and a positive family history of thalassemia (P = 0.001), and frequency of blood transfusion (P = 0.054). Conclusion: The most important risk factors were the duration of blood transfusion for more than 15 years, previous surgery, dental procedure, and splenectomy. Thalassemic patients with older age were at higher risk for HCV infection. The risk increased with patients aged more than 18 years old. A family history of thalassemia was a risk factor for HCV infection.
Comparative analysis of three MCMC methods for estimating GARCH models

GARCH model have been considered as an important and widely employed tool to analyse and forecast variance of the financial market. This study develops three MCMC methods, namely adaptive random walk Metropolis, Hamiltonian Monte Carlo, and Independence Chain Metropolis–Hastings algorithms. It is used to estimate GARCH (1,1) under Normal and Student-t distributions for conditional return distribution. Results on real financial market data indicate that the best method is the approach based on the Independence Chain Metropolis–Hastings algorithm.
