    Identifikasi identitas individu melalui pengenalan wajah secara otomatis merupakan suatu persoalan besar yang menarik dan banyak sekali berbagai macam pendekatan untuk menyelesaikan persoalan ini. Apalagi di dalam skenario kehidupan nyata yang tidak terkontrol, wajah akan terlihat dari berbagai sisi dan tidak selalu menghadap ke depan yang membuat permasalahan klasifikasi menjadi lebih sulit diselesaikan. Dalam Tugas Akhir ini digunakan salah satu metode deep neural networks yaitu Convolutional Neural Networks (CNN) sebagai pengenalan wajah secara real-time yang sudah terbukti sangat efisien dalam klasifikasi wajah. Metode diimplementasikan dengan bantuan library OpenCV untuk deteksi multi wajah dan perangkat Web Cam M-Tech 5MP. Dalam penyusunan arsitekur model Convolutional Neural Networks dilakukan konfigurasi inisialisasi parameter untuk mempercepat proses training jaringan. Hasil uji coba dengan munggunakan konstruksi model Convolutional Neural Networks sampai kedalaman 7 lapisan dengan input dari hasil ekstraksi Extended Local Binary Pattern dengan radius 1 dan neighbor 15 menunjukkan kinerja pengenalan wajah meraih rata-rata tingkat akurasi lebih dari 89% dalam ∓ 2 frame per detik

    Funding Information: Development of this publication was funded by Novartis Pharma AG including medical writing and editorial assistance. The sponsor participated in data analysis, interpretation of the data, and review of the manuscript. Publisher Copyright: © 2022 The Author(s). Published by S. Karger AG, Basel.Introduction: This post hoc analysis applies a fixed dosing stratification approach to patient-level brolucizumab data from the phase III HAWK and HARRIER trials to determine the proportion of patients who would have been assigned to fixed dosing regimens with treatment intervals of 8, 12, or 16 weeks (q8w, q12w, or q16w) based on the presence/absence of disease activity (DA) following the loading phase. The analysis also simulates central subfield thickness (CSFT) data to estimate the anatomical outcomes if the patients had been thus assigned. Of note, the limitations of this analysis include the post hoc nature of the work and the inability to directly compare HAWK and HARRIER with TENAYA and LUCERNE due to the differences in design. Design: This study was a post hoc modelling analysis of patient-level data. Methods: Using patient-level data from HAWK and HARRIER, patients (n = 730) were allocated to a fixed q16w, q12w, or q8w regimen based on assessment of DA at weeks 16 and 20. Two definitions of DA were used: DA 1, based on a phase II study of faricimab, and DA 2, a definition derived from common clinical consideration including visual acuity and anatomical changes. CSFT simulations were performed using a pharmacokinetic/pharmacodynamic model describing CSFT response to anti-VEGF treatment. Outcome measures were modelled patient allocation to fixed regimens and mean CSFT reduction. Results: Using DA definitions 1 and 2, respectively, 78% and 76% of patients in the brolucizumab arm were allocated to a greater than or equal to q12w regimen, and 56% and 52% were allocated to a q16w regimen. Mean reduction in CSFT was similar between the two study drugs with both DA definition assumptions. Conclusions: This analysis demonstrates the potential durability of action and effectiveness of brolucizumab.publishersversionpublishe

    The article offers results of the archaeological study of fortifi cations on the Bilyar fortifi ed settlement – the capital of the Volga Bulgaria in pre-Mongol time. Its defensive structures represent complex systems of walls, ditches and wooden fortifi cations set in several lines. Two main lines of defense were studied: the external and the internal cities. The external belt of defense of the settlement consists of three parallel rows of walls and ditches and was erected in three construction periods. The internal line of defense consists of two rows of walls and ditches, and the study revealed traces of four stages of construction there. All stages of defense works in Bilyar chronologically fi t within the fi rst half of 10th – early 13th centuries

    Photocatalysts based on graphitic carbon nitride (g-C3N4) attracted considerable attention due to their efficiency in hydrogen production and decomposition of organic pollutants in aqueous solutions. In this work, a new approach to synthesis of g-C3N4-based heterostructures with improved photocatalytic properties was proposed. The properties of two different CdZnS/g-C3N4 and ZnIn2S4/g-C3N4 heterostructures synthesized and studied in the same conditions were compared. Pure g-C3N4 photocatalysts as well as CdZnS/g-C3N4 and ZnIn2S4/g-C3N4 heterostructures were synthesized using a one-pot method by calcining the mixture of the initial components. Photocatalytic properties of the synthesized substances were evaluated in a model reaction of rhodamine B decomposition induced by visible light. It was shown that ultrasonic treatment in the presence of a nonionic surfactant enhances the photocatalytic activity of g-C3N4 structures as a result of a higher photocatalyst dispersity. The electronic structures of the CdZnS/g-C3N4 and ZnIn2S4/g-C3N4 heterostructures were analyzed in detail. The photocatalytic activity of heterostructures was found to be 2–3-fold higher as compared with an unmodified g-C3N4 due to formation of a type II heterojunction and Z-scheme structures. Decomposition of rhodamine B occurred mostly via formation of active oxygen radicals by irradiation

    This work reports supercritical water oxidation (SCWO) of organic pollutants in industrial wastewater in the absence and presence of catalysts. To increase the efficiency of the oxidation process, the SCWO of organic compounds in industrial wastewater was performed in the presence of various iron- and manganese-containing heterogeneous catalysts (Fe-Ac, Fe-OH, and Mn-Al). The catalytic and non-catalytic SCWO of organic compounds in wastewater from PJSC “Nizhnekamskneftekhim”, generated from the epoxidation of propylene with ethylbenzene hydroperoxide in the process of producing propylene oxide and styrene (PO/SM), was performed. The effect of operational parameters (temperature, pressure, residence time, type of catalysts, oxygen excess ratio, etc.) on the efficiency of the process of oxidation of organic compounds in the wastewater was studied. SCWO was studied in a flow reactor with induction heating under different temperatures (between 673.15 and 873.15 K) and at a pressure of 22.5 MPa. The reaction time ranged from 1.8 to 4.83 min. Compressed air was used as an oxidizing agent (oxidant) with an oxidant ratio of two to four. A pseudo-first-order model expressed the kinetics of the SCWO processes, and the rate constants were evaluated. In the present work, in order to optimize the operation parameters of the SCWO process, we used the thermodynamic properties of near- and supercritical water by taking into account the asymmetric behavior of the liquid–vapor coexistence curve
