Multilayer Antireflection Coatings for Cover Glass on Silicon Solar Modules

The cover glass on solar modules provides protection for the underlying solar cells but also leads to two forms of power loss: reflection losses and soiling losses. In this work, we report on the design of a broadband multilayer antireflection (MAR) coating designed for use with silicon modules and its advantages over commercial porous SiO<inline-formula><tex-math notation="LaTeX">$_{2}$</tex-math></inline-formula> sol-gel coatings. The six-layer antireflection coating comprising SiO<inline-formula><tex-math notation="LaTeX">$_{2}$</tex-math></inline-formula> and ZrO<inline-formula><tex-math notation="LaTeX">$_{2}$</tex-math></inline-formula> has then been deposited on glass using high-rate pulsed dc magnetron sputtering. The reflection losses are reduced by 2.4% absolute compared with uncoated glass, whereas commercial SiO<inline-formula><tex-math notation="LaTeX">$_{2}$</tex-math></inline-formula> coatings reduce reflection by 2.2%. The increased light reaching the solar cell improves the short-circuit current density (<italic>J</italic><inline-formula><tex-math notation="LaTeX">$_{{{sc}}}$</tex-math></inline-formula>) and spectral response, which increases the conversion efficiency from 17.1% to 17.5%, a relative increase of 2.34%. The coating is environmentally robust and abrasion resistant, whereas porous SiO<inline-formula><tex-math notation="LaTeX">$_{2}$</tex-math></inline-formula> AR coatings are susceptible to abrasion damage and water ingress. The sputtering process used to fabricate the MAR coating is used for high throughput applications by most major glass manufacturers. We also explore the addition of a thin hydrophobic layer of refractive index <italic>n</italic> = 1.35 to the outer surface of the MAR coating. Addition of the hydrophobic layer increases the water contact angle of the MAR coating from 7<inline-formula><tex-math notation="LaTeX">$^{\circ }$</tex-math></inline-formula> to 114<inline-formula><tex-math notation="LaTeX">$^{\circ }$</tex-math></inline-formula>, with a significant increase in antisoiling properties without compromising AR performance. MAR coatings offer improved light transmission and improved durability over commercial porous SiO<inline-formula><tex-math notation="LaTeX">$_{2}$</tex-math></inline-formula> sol-gel AR coatings.
Influence of service quality on customer satisfaction in Serbian logistics practice

Starting from the findings of other authors that logistic service quality indeed affects customer satisfaction, the author of this paper wanted to examine whether this relation existed in the context of Serbian logistics practice. The research was conducted in October 2021 on a sample of 234 respondents who used the services of shipping companies from Serbia. Send questionnaires consisted of three general questions about demographic variables and sixteen closed-ended questions about the perceived service quality based on the dimensions of the SERVPERF model. The researchers assessed the correlation between variables by regression analysis. The results of the research confirm a significant positive correlation between the logistic service quality and customer satisfaction. Responsibility has been shown to have the greatest impact on customer satisfaction, while other characteristics of service quality - reliability and tangibles show a medium, and assurance and empathy almost insignificant positive correlation with customer satisfaction.
Conduction noise attenuation by Fe3O4 thin films attached on microstrip line

Fe3O4 thin films are prepared by reactive sputtering and their magnetic, electric, and noise absorbing properties are investigated with the aim of thin film noise absorbers in gigahertz frequencies. Fe3O4 thin films were deposited on the glass substrate by reactive sputtering. It is found that the precise control of the oxygen partial pressure is the most critical to obtain the single-phase Fe3O4 thin film. The vibrating sample magnetometer measurement indicates that the saturation magnetization is 400emu∕cm3 and the coercive force is about 200Oe. A microstrip line (with a characteristic impedance of 50Ω) was used for the measurement of noise attenuation. Attaching the thin film on the microstrip line, the S11 parameter is increased from −60dB (without a film) to about −15dB (with a film). The S21 parameter is reduced to about −3dB (about 50% in power) in the frequency range of 1–6GHz, which is due to the magnetic loss of the Fe3O4 films. Power absorption (defined by the ratio of power loss to input power.
Linear stability of plane wakes and liquid jets: global and local approach

The global stability of a liquid sheet in gas is studied. The global 3D stability problem for a 2D base flow is formulated, including surface tension of the interface, and the viscosity and density of both phases. The implementational requirements are clarified, and met by using a parallel code for eigenvalue computations based on the mathematical software libraries PARPACK and ScaLAPACK. Preliminary eigenvalue spectra and eigenmodes are presented for the case of water jet surrounded by air.
Atherogenic Index Profiles as Predictor of Cardiovascular Risk in Premenopausal and Menopausal Women

Cardiovascular disease was a disease with impaired function of the heart and blood vessels. Cardiovascular disease was more common in women. Postmenopausal women have a higher risk of cardiovascular disease than premenopausal women. This is because postmenopausal women lack the hormone estrogenin regulating lipid metabolism factors. Decreased production of the hormone estrogen will cause changes in the lipid profile in the blood. Several studies have shown that assessment with the Atherogenic Index (IA) is a good predictor of cardiovascular disease. The atherogenic index was obtained by calculating the TG/HDL-C log. This assessment proved to be more sensitive in assessing the risk of cardiovascular disease compared to the respective lipid profile calculations. This study aimed to compare the profile of the Atherogenic Index in premenopausal women with menopause. This research used the Cross-Sectional Study research method which was presented in the form of data, tables, and narratives. The study results on each 40 menopausal and premenopausal women respectively showed that the comparison value of the atherogenic index in the two categories of subjects was <0.05 (0.00). This showed that there is a significant difference in the mean atherogenic index between postmenopausal and premenopausal women.
Reducing the False Negative Rate in Deep Learning Based Network Intrusion Detection Systems

Network Intrusion Detection Systems (NIDS) represent a crucial component in the security of a system, and their role is to continuously monitor the network and alert the user of any suspicious activity or event. In recent years, the complexity of networks has been rapidly increasing and network intrusions have become more frequent and less detectable. The increase in complexity pushed researchers to boost NIDS effectiveness by introducing machine learning (ML) and deep learning (DL) techniques. However, even with the addition of ML and DL, some issues still need to be addressed: high false negative rates and low attack predictability for minority classes. Aim of the study was to address these problems that have not been adequately addressed in the literature. Firstly, we have built a deep learning model for network intrusion detection that would be able to perform both binary and multiclass classification of network traffic. The goal of this base model was to achieve at least the same, if not better, performance than the models observed in the state-of-the-art research. Then, we proposed an effective refinement strategy and generated several models for lowering the FNR and increasing the predictability for the minority classes. The obtained results proved that using the proper parameters is possible to achieve a satisfying trade-off between FNR, accuracy, and detection of the minority classes.

Modified solid in oil nanodispersion containing vemurafenib-lipid complex- in vitro/ in vivo study

Background: Vemurafenib (VEM) was a licensed drug for the treatment of skin melanoma and is available only in the market as oral tablets prescribed in huge doses (1920 mg/day). One reason for the high dose is vemurafenib's low oral bioavailability. Methods: VEM-lipid complex (DLC) was predicted based on Conquest and Mercury programs and prepared using the solvent evaporation method using the lipid (phosphatidylethanolamine). DLC was subjected to characterization (FT-IR, Raman spectroscopy, DSC, TGA, P-XRD, and FESEM) to confirm complexation. DLC was used to prepare solid in oil nanodispersion (DLC-SON) and subjected to in vitro, ex vivo, and in vivo evaluation in comparison to our recently prepared conventional SON (VEM-SON) and DLC-control. Results: Conquest and Mercury predict the availability of intermolecular hydrogen bonding between VEM and phosphatidylethanolamine (PE). All characterization tests of DLC ensure the complexation of the drug with PE. Ex vivo studies showed that the drug in DLC-SON has significantly (P<0.05) higher skin permeation than DLC-control but lower drug permeation than conventional SON but it has a higher % skin deposition (P<0.05) than others. The half-maximal inhibitory concentration (IC50) of the prepared DLC-SON is significantly high (P<0.05) in comparison to the conventional SON and pure VEM. In vivo permeation using confocal laser scanning microscopy (on the rat) results indicated that both conventional SON and DLC-SON can cross the SC and infiltrate the dermis and epidermis but DLC-SON has a higher luminance/gray value after 24 h in the dermis in comparison to the conventional SON. Conclusion: The novel lipid complex for VEM prepared using PE as a lipid and enclosed in SON showed higher anticancer activity and topical permeation as well as sustained delivery and good retention time in the dermis that localize the drug in a sufficient concentration to eliminate early diagnosed skin melanoma.

How Ambidextrous Human Resource System Affect Employee Creativity? A Study in the Pakistani Context

Strategic human resource management scholars have devoted substantial research to determine the relationship between human resource management (HRM) and creativity. It has focused primarily on HRM architecture at the macro level: exploring the effect of the HRM system on performance related to capacity building, skills and competencies. In framing that HRM architecture, this macro focus informs organisations about how to promote creativity. However, literature on how a creativity-targeted HRM system, for instance, the ambidextrous HR system, influences employees’ perceptions and experiences to be more creative at the individual level is still limited. The multilevel perspective on how the HRM system can potentially promote the creativity of employees is still limited. The multilevel data from 100 HR heads and 400 faculty employees of public and private sector universities show that the top-down effect of the ambidextrous HR system on employee creativity is partially mediated by ambidextrous learning and organisation-based self-esteem. Based on the findings, the study offers practical and theoretical implications.
Event‐based Dynamic Graph Drawing without the Agonizing Pain

Temporal networks can naturally model real‐world complex phenomena such as contact networks, information dissemination and physical proximity. However, nodes and edges bear real‐time coordinates, making it difficult to organize them into discrete timeslices, without a loss of temporal information due to projection. Event‐based dynamic graph drawing rejects the notion of a timeslice and allows each node and edge to retain its own real‐valued time coordinate. While existing work has demonstrated clear advantages for this approach, they come at a running time cost. We investigate the problem of accelerating event‐based layout to make it more competitive with existing layout techniques. In this paper, we describe the design, implementation and experimental evaluation of MultiDynNoS, the first multi‐level event‐based graph layout algorithm. We consider three operators for coarsening and placement, inspired by Walshaw, GRIP and FM3, which we couple with an event‐based graph drawing algorithm. We also propose two extensions to the core algorithm: AutoTau and Bend Transfer. We perform two experiments: first, we compare MultiDynNoS variants to existing state‐of‐the‐art dynamic graph layout approaches; second, we investigate the impact of each of the proposed algorithm extensions. MultiDynNoS proves to be competitive with existing approaches, and the proposed extensions achieve their design goals and contribute in opening new research directions.
The story of a physical science curriculum: transformation or transmutation?

Abstract Recently Curriculum and Assessment Policy Statements (CAPS) were introduced in South Africa in response to confusion precipitated by previous curriculum documents. The purpose of this paper is to explore that confusion in the subject ‘Physical Sciences’ and consider the nature of the transformation from the previous curriculum by looking at curriculum documents and examination papers. We present a two phase curriculum change model which suggests that congruency between curriculum documents and examinations is critical for effective curriculum change. We analyse the pre-CAPS curriculum, the National Curriculum Statement (NCS), on its own terms by using the stated outcomes as our reference point. Our analysis reveals that the weighting and conceptualization of the outcomes shifted through successive documents, which undermined congruency between the documents and meant that content-oriented science masqueraded as inquiry-oriented science. This led to a retreat from the original vision of weighting skills and relevance equally with content. The examinations took this retreat a step further. Evidence of the retreat is that the nature of the questions asked in the 2008 examinations on the NCS was similar to that of the 2007 examinations on the previous curriculum which had not changed since apartheid. However, in the NCS examinations there was a small shift towards contextualisation and inquiry oriented science. The retreat means the vision of transformation which was the rationale for the NCS curriculum was eroded—instead of transformation, there was transmutation back to the old apartheid curriculum. The Physical Sciences CAPS cements the retreat and creates new confusion by changing the syllabus again without signposting the change.
Cultural Resources, Listening Comprehension of Intermediate Iranian EFL Learners and their Emotional Intelligence

The notion of emotional intelligence (EQ or EI) was provided to complement general intelligence. This study intended to study the influence of emotional intelligence on listening comprehension of junior high school EFL learners from both genders when using culture-based materials. In so doing, a number of 50 Iranian intermediate level EFL learners were selected using the Oxford Quick Placement Test (OQPT). In addition, Trait Emotional Intelligence Questionnaire was employed. The listening test was administered first. Participants were classified into an experimental and a control group. In the experimental group, students were exposed to listening materials such as special expressions, idioms, and conversations. After ten sessions, participants participated in the listening post-test. The results of an independent samples t-test showed that the performance of the participants in the two groups was significantly different. Moreover, one-way ANOVA and post-hoc analysis revealed that gender significantly affects the listening skills of EFL learners with varying degrees of emotional intelligence when using cultural material in listening lessons. The findings of this study can lead language teachers to include materials as listening pieces about cultural entities to improve the listening ability of language learners.
WIGHT: Wired Ghost Touch Attack on Capacitive Touchscreens

The security of capacitive touchscreens is crucial since they have become the primary human-machine interface on smart devices. To the best of our knowledge, this paper presents WIGHT, the first wired attack that creates ghost touches on capacitive touchscreens via charging cables, and can manipulate the victim devices with undesired consequences, e.g., allowing malicious Bluetooth connections, accepting files with viruses, etc. Our study calls for attention to a new threat vector against touchscreens that only requires connecting to a malicious charging port, which could be a public charging station, and is effective across various power adapters and even USB data blockers. Despite the fact that smartphones employ abundant noise reduction and voltage management techniques, we manage to inject carefully crafted signals that can induce ghost touches within a chosen range. The underlying principle is to inject common-mode noises over the power line to avoid being effectively filtered yet affect the touch measurement mechanism, and synchronize the malicious noise with the screen measurement scanning cycles to place the ghost touches at target locations. We achieve three types of attacks: injection attacks that create ghost touches without users touching the screen, alteration attacks that change the detected legitimate touch position, and Denial-of-Service attacks that prevent the device from identifying legitimate touches. Our evaluation on 6 smartphones, 1 tablet, 2 standalone touchscreen panels, 6 power adapters, and 13 charging cables demonstrates the feasibility of all three type attacks.
Spectral data for G-Higgs bundles

In particular, we consider the case of G a split real form, as well as G = SL(2,R), U(p,p), SU(p,p), and Sp(2p,2p). Further, we give some applications of our results, and discuss open questions.
Evaluation of Macrophage Activation Syndrome in Patients with Systemic Juvenile Idiopathic Arthritis: A Single Center Experience

Objectives Macrophage activation syndrome (MAS) is a severe complication of systemic juvenile arthritis (sJIA), and early diagnosis is critical for survival. The objective of this study was to evaluate the 2016 MAS classification criteria in a Danish sJIA cohort and to compare different sets of criteria for the early identification of MAS including the HLH-2004 diagnostic guidelines, MS score, and the ferritin/ESR ratio. Methods Data was extracted from medical charts of 32 patients with sJIA from a single Danish paediatric rheumatology center diagnosed between January 2014 and June 2021. Patients who met the 2016 MAS classification criteria were classified as having MAS. From a receiver operating characteristic (ROC) plot, the area under the curve (AUC) was calculated for the prediction of patients with MAS according to the 2016 MAS classification criteria using either MS score or the ferritin/ESR ratio. Results Of the cohort, eight (25%) patients were classified as having MAS according to the 2016 MAS classification criteria compared to only three (9.4%) patients fulfilling the HLH-2004 diagnostic guidelines, all of which had recurrent MAS. The ferritin/ESR ratio showed the highest sensitivity (100%) but the lowest specificity (72.2%). In comparison, the MS score had a higher specificity (90.9%) for the identification of MAS according to the 2016 classification criteria. In our cohort, the most optimal cut-off point for the ferritin/ESR ratio was ≥19.4 (sensitivity: 100%, specificity: 72.2%) and ≥ -1.5 for the MS score (sensitivity: 71.4%, specificity: 91.7%), respectively. Conclusion The 2016 MAS classification criteria were a valuable tool in the discrimination of sJIA with and without MAS. The HLH-2004 diagnostic guidelines showed the lowest sensitivity, ferritin/ESR ratio, and the lowest specificity compared to the MS score where an acceptable high sensitivity and specificity was found.
Investigation of interleukin-8 from patients infected Trichophyton rubrum

The most prevalent form of chronic dermatophytoses causing pathogenic fungus in humans is Trichophyton rubrum. Keratinocytes, the main epidermal cells, are crucial in local immune interactions because they represent the first line of defense against microbial assaults, skin In response to varied stimuli, keratinocytes express a wide range of receptors and create host defense peptides, cytokines, and chemokines, this immunological study's objective was to use an ELISA to determine the function of inflammatory interleukins (IL-8) in Trichophyton rubrum patients. The study included 30 patients with verified Trichophyton rubrum and 10individuals as a control group. Age, gender, the date of the surgery, the patient's occupation, their address, and the findings were all collected for every infected patient, the ELISA (Linked Immuno-sorbent Assay) technique was used to measure immune cells' cellular kinetics for secreting interleukin-8 were calculated And there was a significant increase in the level of significance for persons infected with interleukin-8 (p > 0.05), compared to control persons.
