Add-on therapy with different non-steroidal anti-inflammatory agents in the management of non-infectious, non-necrotizing episcleritis

Background: Episcleritis is a common ocular inflammatory disease that can cause red eye. It is usually managed using single or combined topical corticosteroids and topical or oral non-steroidal anti-inflammatory drugs (NSAIDs) as directed by clinical response. However, recurrence is possible. This study aimed to compare the effects of add-on therapies using different topical NSAIDs in the management of treatment-naive, non-infectious, non-necrotizing episcleritis. Methods: Seventy-five eyes of 75 patients with non-infectious, non-necrotizing unilateral episcleritis were included in this study. Patients were allocated to one of three groups based on the NSAID used as add-on therapy: topical diclofenac sodium 0.1% (group D), topical nepafenac 0.1% (group N1), and topical nepafenac 0.3% (group N3). The time to symptom disappearance was defined as the recovery time. Results: There were no statistically significant differences in age, sex, initial best-corrected distance visual acuity, and intraocular pressure between groups (all P > 0.05). The mean recovery times of groups D and N1 were comparable (12.86 ± 5.35 days and 11.45 ± 5.42 days, respectively) (P > 0.05). However, the mean recovery time of group N3 was significantly shorter (9.70 ± 3.80 days, P < 0.05). Recurrence was observed in only one patient in group N1 at 3 months, and symptoms resolved when the same medication was reinstituted. Furthermore, we noted no side effects during the follow-up period for any of the treatment modalities. Conclusions: All three topical NSAIDs were effective add-on therapies in the management of non-infectious, non-necrotizing unilateral episcleritis. However, once-daily administration of topical nepafenac 0.3% had a shorter recovery time than topical diclofenac 0.1% and topical nepafenac 0.1%.
EVALUATION OF VOLUMETRIC MAINTENANCE AFTER SINGLE AND MULTIPLE DENTAL EXTRACTION USING LAMINATED TITTANIUM SHEET -

The post-extraction border preservation is a fundamental procedure to the maintenance of alveolar volume prioritizing an aesthetical and functional improvement in the im- plant’s positioning. This thesis’s objective was to evaluate the titanium membrane (Sur- gitime Titânio Seal® – Bionnovation, Brasil) covered post extraction alveolar bone di- mensional alterations, while comparing areas to unitary and multiple exodontias. 20 pre and post-operation tomographical exams were evaluated, from areas where unitary den- tal extractions (G1) and multiple dental extractions (G2) occurred. In every case, using the Titanium Seal post extraction alveolar preservation treatment, with no alveolus fil- ling. Measurements were obtained from the central region of the axial and area sections previous to the proceadure at the most cervical zones of bone peaks, plus two more me- asurements from 2 and 4 mm under the first point. Following, those measurements were transfered from the previously obtained absolute refurbishment length. Measurements were taken from the new total border length – at the central virtually representative re- gion of the extracted dental element. In both groups, differences among baseline and 6 months in height: -0,95mm ±0,89 (G1) and -1,95mm ±1,04 (G2) and 2mm volume: -1,10mm ±0,48 (G1) and -2,48mm ±1,08 (G2) were statistically representative. In any cases, the 4mm volume presented differences. Statistically, the bone loss was higher in Group 2. The present study have shown that the titanium-laminated sheet was effective when it comes to post-extraction alveolar preservation, in both unitary and multiple ex- tractions.
Microstructural and Mechanical Characteristics of Pure-Cu/brass Dissimilar Joints Welded by Friction Stir Welding Using Various Process Parameters

FSW (friction stir welding) is a solid-state joining method that attracts interest from all industries. The influence of various tool rotational speeds on the microstructure and mechanical characteristics of dissimilar pure Cu-brass joints has been investigated. The travel speed and vertical load were kept constant in the welding trials, at 40 mm/min and 10 kN, respectively, while the tool rotational speed varied from 1000 to 1400 rpm. The increase of the rotational speed to 1400 rpm resulted in degradation of the mechanical properties. The stir zone grain structure was refined; however, the grain size was irregular. Grain refining occurs due to a continuous and discontinuous dynamic recrystallization mechanism. In the grain interior, there were many large dislocations, identifying that incomplete recrystallization took part within the SZ. Instead, the lower rotational speed, i.e., 1000 rpm, led to more uniform grain refinement in the SZ. Moreover, in contrast to the welded zone where very fine grains exist, the base metal and thermomechanically heat-affected zone display coarser grains. Because of the microstructural modification, the stir zone’s mechanical characteristics were higher than the base materials, and the mechanical strength and plasticity were simultaneously upgraded. These results indicate that the size of the grains is independent of rotational speed. And mechanical properties like hardness and impact strength decreased as the rotational speed increased.
Optimal energy management in smart grid with internet of things using hybrid technique

This paper proposes an energy management system (EMS) in smart grid based on Internet of Things (IoT) configuration using hybrid approach. The proposed approach is joint execution of Multi-fidelity meta-optimization and Turbulent Flow of water based optimization (TFWO), hence it is known as M2FWO technique. The main objective of this proposed EMS is to better manage power with the resources of Smart Grid by constantly monitoring data from the IoT-based communication framework. Here, each home device is connected to data acquisition module is utilized to facilitate the demand response (DR) growth for energy management system in smart grid. The framework collects DR from every smart home device and then transmits the data to the centralized server. The transmitting data is enabled by M2FWO method. The smart grid IoT framework enhances the feasibility of these networks makes better use of obtainable resources. The proposed system is in charge to satisfy the total supply with energy requirement. Finally, the proposed model is stimulated on MATLAB/Simulink site, then the efficiency is examined with existing methods.
Avaliação de Modelos de Acesso à Memória de Dados em Arquiteturas Super Escalares

The execution of data memory access instructions is an important issue for processor performance, due to the high frequency of such instructions. This work focus on the execution of memory access instructions in superscalar architectures. Several different memory access models are evaluated, ranging from a simple mechanism in which memory access instructions are executed sequentially in order, to a mechanism which executes memory access instructions in pipeline, out of order and speculatively.
Fine classification of the emission-line spectra of active galaxies

We refine the classification of galaxies by activity types based on a number of samples of objects having homogeneous optical medium resolution spectra from SDSS. SDSS spectra provide many spectral features and details that were not available before. Three diagnostic diagrams and eye examination have been used and the combined activity types have been derived. A fine classification scheme was developed, where QSOs have subtypes like Seyferts, Narrow Line QSOs are introduced, subclasses for Narrow Line Seyfert 1s are used and Composite spectrum objects have their subtypes. This classification scheme much better describes all fine details in the optical spectra and allows further study of active galaxies by the subtypes for better understanding the Unified model and the physical properties of AGN and Starbursts.
A Design Methodology for Achieving Near Nyquist Continuous Time Pipelined ADCs

Continuous-time pipelined (CTP) ADCs have shown the potential to alleviate the challenges of discrete-time (DT) pipelined converters with Multi-GHz bandwidth, but have so far required an oversampling ratio (OSR) of at least 4. After elucidating the factors that limit CTP bandwidth, this paper presents a design methodology for near-Nyquist CTP ADCs. The delay circuit is optimized to match the ADC/DAC path in both its broadband magnitude response and phase. The residue filter response is optimized to prevent image signals from overloading the subsequent stage. We show that practical circuits can realize these optimized responses and extend the bandwidth of the CTP architecture to OSRs of 1.5-2.0, essentially equivalent to the OSR of DT converters when allowing for practical anti-aliasing. The direct path (i.e. delay) and the residue-amplifying filter circuits required for 3 GHz bandwidth are incorporated into a complete 4-bit 10 GS/s CTP ADC stage in a 28nm CMOS prototype. Simulation and measurement results confirm that CTP ADCs can operate at a near-Nyquist sampling rate with an OSR of 1.7.
A General Digital Predistortion Linearization Scheme for Hybrid Beamforming System

Hybrid beamforming multiple-input multiple-output (MIMO) system has attracted a lot of attention in recent years since it significantly reduces the hardware cost compared to the fully digital beamforming system. However, with hybrid beamforming, the one-to-one mapping between the radio frequency (RF) chain and the nonlinear power amplifier (PA) is destroyed. The PA nonlinearity cannot be compensated by conventional digital predistortion (DPD) algorithms. In this article, we propose a novel multiple-input DPD model for hybrid beamforming MIMO systems. An extra digital compensation block is introduced in the feedback path. With the feedback compensation block, the proposed DPD can linearize the PA output signal as well as the aggregated far-field signal. What is more, we propose a DPD estimation algorithm with much reduced complexity. Comparing to existing solutions, the proposed scheme achieves satisfactory performance for hybrid beamforming system. It does not rely on the measurement of the channel or the assumption of massive antennas. Simulation results demonstrate the effectiveness of the proposed DPD scheme.
Current Progress in Natural Degradation and Enhanced Removal Techniques of Antibiotics in the Environment: A Review

Antibiotics are used extensively throughout the world and their presence in the environment has caused serious pollution. This review summarizes natural methods and enhanced technologies that have been developed for antibiotic degradation. In the natural environment, antibiotics can be degraded by photolysis, hydrolysis, and biodegradation, but the rate and extent of degradation are limited. Recently, developed enhanced techniques utilize biological, chemical, or physicochemical principles for antibiotic removal. These techniques include traditional biological methods, adsorption methods, membrane treatment, advanced oxidation processes (AOPs), constructed wetlands (CWs), microalgae treatment, and microbial electrochemical systems (such as microbial fuel cells, MFCs). These techniques have both advantages and disadvantages and, to overcome disadvantages associated with individual techniques, hybrid techniques have been developed and have shown significant potential for antibiotic removal. Hybrids include combinations of the electrochemical method with AOPs, CWs with MFCs, microalgal treatment with activated sludge, and AOPs with MFCs. Considering the complexity of antibiotic pollution and the characteristics of currently used removal technologies, it is apparent that hybrid methods are better choices for dealing with antibiotic contaminants.
Understanding 2D-IR Spectra of Hydrogenases: A Descriptive and Predictive Computational Study

[NiFe] hydrogenases are metalloenzymes that catalyze the reversible cleavage of dihydrogen (), a clean future fuel. Understanding the mechanism of these biocatalysts requires spectroscopic techniques that yield insights into the structure and dynamics of the [NiFe] active site. Due to the presence of CO and ligands at this cofactor, infrared (IR) spectroscopy represents an ideal technique for studying these aspects, but molecular information from linear IR absorption experiments is limited. More detailed insights can be obtained from ultrafast nonlinear IR techniques like IRpump−IRprobe and two-dimensional (2D-)IR spectroscopy. However, fully exploiting these advanced techniques requires an in-depth understanding of experimental observables and the encoded molecular information. To address this challenge, we present a descriptive and predictive computational approach for the simulation and analysis of static 2D-IR spectra of [NiFe] hydrogenases and similar organometallic systems. Accurate reproduction of experimental spectra from a first-coordination-sphere model suggests a decisive role of the [NiFe] core in shaping the enzymatic potential energy surface. We also reveal spectrally encoded molecular information that is not accessible by experiments, thereby helping to understand the catalytic role of the diatomic ligands, structural differences between [NiFe] intermediates, and possible energy transfer mechanisms. Our studies demonstrate the feasibility and benefits of computational spectroscopy in the 2D-IR investigation of hydrogenases, thereby further strengthening the potential of this nonlinear IR technique as a powerful research tool for the investigation of complex bioinorganic molecules.
A Study of the Jacobi Stability of the Rosenzweig-MacArthur Predator-Prey System through the KCC Geometric Theory

In this paper, we consider an autonomous two-dimensional ODE Kolmogorov-type system with three parameters, which is a particular system of the general predator–prey systems with a Holling type II. By reformulating this system as a set of two second-order differential equations, we investigate the nonlinear dynamics of the system from the Jacobi stability point of view using the Kosambi–Cartan–Chern (KCC) geometric theory. We then determine the nonlinear connection, the Berwald connection, and the five KCC invariants which express the intrinsic geometric properties of the system, including the deviation curvature tensor. Furthermore, we obtain the necessary and sufficient conditions for the parameters of the system in order to have the Jacobi stability near the equilibrium points, and we point these out on a few illustrative examples.
Clustering of the European Union member states based on money laundering measuring indices

The number of enforcement actions and fines for non-compliance with anti-money laundering (AML) regulations continues climbing year after year, and the year 2021 was no exception to this tendency. Globally, authorities remain harsh, and AML fines in Europe, the United States, and the United Kingdom have been increasing (Global Anti-Money Laundering Regulations, 2021). According to the UN estimations, the amount of money annually laundered worldwide amounts to 2–5% of the world’s Gross Domestic Product (GDP), or in absolute numbers - to 800 billion-2 trillion US dollars. Such high figures indicate that national governments are indeed facing a serious problem of money laundering. In this article, clustering is employed to group the EU member states by their money laundering measuring indices in order to assess the EU legal framework in terms of money laundering prevention. State clustering could help the relevant EU institutions, such as Financial Intelligence Units (FIUs), Europol, International Monetary Fund (IMF), national governments and others, to develop the most effective measures to diminish the problem of money laundering and to complement their regulatory framework. Money laundering is usually associated with criminal activities that generate large amounts of illegal financial resources. In the most general sense, money laundering refers to the process of disguising the true origin, ownership, disposal and movement of particular proceeds, property or property rights. The results of the empirical research propose that money laundering reduction calls for a higher number of suspicious transaction reports (STRs), lower levels of corruption and improvement of the legal framework in terms of money laundering prevention in the EU. The research methods cover comparative and systematic literature analysis, and hierarchical cluster analysis. The cluster analysis of the EU member states (28 countries) uses the number of reports filled with FIU between 2006-2014, the 2012-2020 Basel AML Index and the 1998-2018 CPI data.
A genetic and molecular study of pollen tube growth in Arabidopsis

Sexual plant reproduction involves the deposition of pollen on top of the stigma, followed by pollen germination, pollen tube growth within the pistil and leading to delivery of the sperm cells to the embryo sac for fertilisation. One approach to study genes essential for this unique intercellular processes involves the screening of Arabidopsis T-DNA tagged populations and searching for lines with a non-Mendelian segregation of marker genes, due to reduced T-DNA transmission. The main focus of this thesis is the genetic, molecular and cellular characterization of a male gametophytic mutant, found in such a mutant population by segregation distortion analysis. The hemizygous mutant line TJ995 showed a severe defect in male T-DNA transmission efficiency, with only 2% of the mutant pollen tubes being able to achieve fertilization. No defect through the female gametophyte was found. TJ995 showed bursting of the mutant pollen during pollen germination and pollen tube growth in vitro, and the mutant was called bursting pollen (bup/+). Molecular and genetic studies showed that the male gametophytic defect of bup/+ was due to the T-DNA insertional mutation of gene At5g04480 (BURSTING POLLEN). BUP encodes a golgi-resident type II transmembrane protein showing similarity with family 1 glycosyl transferases, and appears to be strongly conserved through evolution. BUP and its Arabidopsis homologue BUP like (BPL) are both constitutively expressed at low levels in pollen and in vegetative tissues, but appear to have different functions within the male gametophyte. We hypothesize that BUP is involved in the synthesis of pectin present in the intine layer of the pollen (tube) wall and in sporophytic cell walls, and as such is important for the pollen wall and cell wall plasticity and strength.
Stars at high resolution: a library of synthetic spectra from 850 to 7000

We present a new theoretical library of about 2500 high-resolution spectra of stars covering a wide wavelength range from 850 to 7000 Å. The set consists of an ultraviolet grid (1690 spectra), at an inverse resolution R=50 000, and an optical grid (832 spectra), at R=500 000, and spans a large volume in the fundamental parameters space (i.e. Teff , log g, [M/H]). The synthetic spectra, based on the ATLAS 9 model atmospheres, have been computed with the SYNTHE code developed by R.L. Kurucz. These properties make the library an updated tool, especially suitable to match high-quality observing data from the new-generation telescopes.
Light transmittance of mahogany wood treated with 20% hydrogen peroxide solution

There is an increased research interest in methods for transparent wood production and its use. Wood transparency could be achieved by its delignification followed by an impregnation process with polymers having proper optical properties. However, delignification processes are mainly time consuming and not environmentally friendly. The possibility of treating mahogany wood (Swietenia macrophylla King) with 20% hydrogen peroxide for 70, 100, 135, and 170 min at 103 °C is presented in this research. According to the treatment duration, lignin content decreased 40 to 94% relative to its initial content in the control samples, whilst the cell structure remained intact. Due to the light scatter effect, caused mainly by wood tissue structure, the direct optical transmittance of treated samples in the visible light spectrum (400 to 800 nm) was less than 40%. Simultaneously, the total optical transmittance of samples treated for 100 and 135 min reached values between 70 to 80% with high values of the haze at approximately 30 and 60%. Optical transmittance in the visible spectrum area of the samples treated for 170 min was from 45 to 80% and the haze from 25 to 45%.
Mottness induced superfluid phase fluctuation with increased density

Recent observation of diminishing superfluid phase stiffness upon increasing carrier density in cuprate high-temperature superconductors is unexpected from the quantum density-phase conjugation of superfluidity. Here, through analytic estimation and verified via variational Monte Carlo calculation of an emergent Bose liquid, we point out that Mottness of the underlying carriers can cause a stronger phase fluctuation of the superfluid with increasing carrier density. This effect turns the expected density-increased phase stiffness into a dome shape, in good agreement with the recent observation. Specifically, the effective mass divergence due to ‘jamming’ of the low-energy bosons reproduces the observed nonlinear relation between phase stiffness and transition temperature. Our results suggest a new paradigm, in which unconventional superconductivity in some strongly correlated materials is described by physics of bosonic superfluidity, as opposed to pairing-strength limited Cooper pairing.
University’s Factors Influencing the Entrepreneurial Drive of Business Students: Empirical Study in Vietnam

This study explores and examines the effects of the curriculum and content of entrepreneurship as well as perceived university support on the entrepreneurial drive of students who are majoring in business administration. The research was conducted with a sample of 156 senior students at the most popular universities in the business fields in Hanoi, the capital city of Vietnam. Based on a quantitative methodology using PLS-SEM, the study has revealed that the curriculum and content of entrepreneurship significantly affected the students’ entrepreneurial drive. However, this study has not found a relationship between perceived university support and entrepreneurial drive. Based on the discussion of the findings, the study has generated novel suggestions for universities and business faculties with similar characteristics in completion of their curriculum and content of entrepreneurship. Furthermore, this study also suggested further research directions to develop the appropriate approaches to university support.
