Comparison of clinical outcomes of 2 platforms for topography-guided LASIK in primary eyes

Corneal topography-guided LASIK of WaveLight and SCHWIND platforms are comparable in visual and refractive outcomes. The EX500 Contoura LASIK may ablate less corneal tissue due to smaller effective optical zone. Purpose: To compare differences in visual, refractive, and ablating outcomes between corneal topography-guided laser in situ keratomileusis (LASIK) by SCHWIND AMARIS and WaveLight Contoura for myopia and myopic astigmatism correction. Setting: Department of Refractive Surgery, Guangzhou Aier Eye Hospital, Guangzhou, China. Design: Prospective nonrandomized study. Methods: Patients treated with LASIK to correct ametropia and corneal higher-order aberrations (HOAs) with 6.5 mm of plan optical zone were recruited. In the AMARIS platform, there were 2 centration strategies: the symmetric (AA) and asymmetric (AS) offset modes. In the WaveLight platform, there was only symmetric offset (ES) mode. HOAs, contrast sensitivity, effective optical zone (EOZ), ablation depth, and ablating center were evaluated 3 months after the operation. Results: The study included 138 eyes. At 3 months after operation, the postoperative manifest refractive spherical equivalent was 0.04 ± 0.34 diopters (D), 0.06 ± 0.25 D, and −0.09 ± 0.21 D in AS, AA, and ES groups, respectively (P = .018). The EOZs of the AS and AA groups were 5.01 mm and 4.96 mm, and both were larger than 4.88 mm in the ES group (P = .04 and .03, respectively). The ablation depth of the AS group was 103.6 μm, which were larger than 86.6 μm in the AA group and 91.2 μm in the ES group. Conclusions: The SCHWIND AMARIS and WaveLight EX500 corneal topography-guided LASIK achieved comparable and excellent visual and refractive outcomes. The EX500 Contoura LASIK ablated less corneal tissue because of the smaller EOZ compared with the AMARIS, with a similar plan optical zone.
An integrative review of studies of condom use among Korean college students

Purpose The purpose of this study was (a) to synthesize studies of condom use among South Korean college students, and (b) to appraise the quality of each article using Gough’s weight of evidence. Methods Studies published in English and Korean were searched in electronic databases using the terms “student or college student or university student or undergraduate”, “condom”, and “Korea*”. Results Twenty studies met the inclusion criteria, showed appropriate quality, and were therefore selected for review. The variables related to condom use were measured in terms of condom-related factors, factors related to non-condom-related knowledge and attitudes, and other factors. Knowledge, attitudes, and self-efficacy were associated with condom use, and there were differences in condom-related factors among men and women. Conclusion Based on these findings, it was confirmed that sexual education is needed for both men and women to promote condom use. Education on condom use should not only focus directly on condoms, but should also address other aspects of knowledge and attitudes to influence health beliefs. In addition, developing educational programs targeting adolescents and parents will have a positive effect on college students’ condom use.
Ionospheric D Region Disturbances due to FAC and LEP Associated With Three Severe Geomagnetic Storms as Observed by VLF Signals

The effects of one super and two intense storms on three European very low frequency (VLF) transmitter signals received at Algiers (Algeria) station, are presented. Two VLF transmitters (DHO and GQD) are located almost at the same mid‐latitude and third transmitter (NRK) at a high latitude, allowing us to study the latitudinal dependence of the storm effect on the VLF propagation. Two kind of ionospheric disturbances were considered: Direct effect of the field aligned currents (FACs) and the second concerning with the lightning‐induced electron precipitation (LEP) events. The FACs effect was clearly evident on the recorded signal amplitude during the daytime and nighttime. Our analysis of the short‐duration VLF perturbations due to LEP events showed that the ducted and non‐ducted LEPs are the majority of VLF perturbations and a small fraction of LEP events was associated with magnetospherically reflected waves on the high latitude transmitter path (NRK–Algiers). The coincident observation of LEP on the mid‐latitude transmitters (DHO and GQD) signals implies that the disturbance was large as much as the distance between the two transmitters (728 km). The modeling using Long‐Wave Propagation Capability (LWPC) code of LEP associated VLF perturbations considering Gaussian distribution of electron density enhancements, showed a decrease in the D‐region reference height from its usual value 87 km to 83.3 km for ducted LEP and 80.3 km for non‐ducted LEP event and that the non‐ducted event exhibited a wider disturbed region.

Irradiation Effects on The Sensitivity of ZnO Thin Films Synthesized on Glass Substrate by Sol-gel Method

This work investigates the structural, optical, and surface properties of ZnO thin films prepared by sol-gel method. The effect on waveguide sensor was examined at different irradiation durations of alpha particles. The X-ray diffraction (XRD) measurements revealed that the crystalline phase of ZnO thin films does not change after irradiation and showed a hexagonal structure of wurtzite type with an orientation toward (002). Moreover, ZnO thin films absorbance was increased with increasing irradiation time, whereas the transmittance was decreased. Additionally, increasing the irradiation time of alpha particles caused an increase in the extinction coefficient and the imaginary part, while the optical energy gap of the ZnO samples was decreased. Finally, the maximum value of sensitivity was 42%, found at 6 min of irradiation duration.
Fault-Source-Based Probabilistic Seismic Hazard and Risk Analysis for Victoria, British Columbia, Canada: A Case of the Leech River Valley Fault and Devil’s Mountain Fault System

This study develops a fault-source-based seismic hazard model for the Leech River Valley Fault (LRVF) and the Devil’s Mountain Fault (DMF) in southern Vancouver Island, British Columbia, Canada. These faults pose significant risks to the provincial capital, Victoria, due to their proximity and potentially large earthquake magnitudes. To evaluate the effects of including these faults in probabilistic seismic hazard analysis and city-wide seismic loss estimation for Victoria, a comprehensive sensitivity analysis is conducted by considering different fault rupture patterns and different earthquake magnitude models, as well as variations in their parameters. The aim is to assess the relative contributions of the LRVF-DMF system to the overall seismic hazard and risk in Victoria at different return periods. The consideration of the LRVF-DMF system as a potential seismic source increases the seismic risk assessment results by 10 to 30%, especially at the high return period levels. The sensitivity analysis results highlight the importance of determining the slip rate for the fault deformation zone and of specifying the earthquake magnitude models (e.g., characteristic versus truncated exponential models). From urban seismic risk management perspectives, these nearby faults should be considered critical earthquake scenarios.

Contributions of Isoprene, Monoterpenes, ss-caryophyllene, and Toluene to Secondary Organic Aerosol in Hong Kong during the Summer of 2006

[1] Isoprene, monoterpenes, β-caryophyllene, and toluene are known to be important secondary organic aerosol (SOA) precursors. In this study, characteristic SOA tracers of these precursors were quantified in ambient samples of PM2.5 taken in Hong Kong and their contributions to SOA were estimated using a tracer-based method. Samples were collected every other day from four sampling sites during a field measurement campaign in the summer of 2006. Fourteen SOA tracers, along with 24 other polar oxygenated compounds, were identified and quantified using gas chromatography/ion trap mass spectrometry with prior trimethylsilylation. Concentrations of the individual tracers ranged from a few tenths to a few hundreds ng m−3. The tracer concentrations were found to be 1 order of magnitude higher on days under regional transport influences due to elevated oxidant levels than on days under mainly local emissions influences. Using the measured SOA tracer concentrations in the ambient aerosols and laboratory-derived tracer mass fractions reported by Kleindienst et al. (2007), we estimated that the average SOA attributable to isoprene, monoterpenes, β-caryophyllene, and toluene was 8.83 μg m−3 on days under regional transport influences versus 0.99 μg m−3 on days under mainly local emissions influences, accounting for approximately 49% and 21%, respectively, of the ambient OC concentrations. The tracer-based estimates indicate that monoterpenes and β-caryophyllene are significant contributors to ambient PM2.5 in the summer, which may be due to the high emissions of these biogenic hydrocarbons in Hong Kong.

Cu-Sn binary metal particle generation by spray pyrolysis

ABSTRACT Cu-Sn binary particles were generated via spray pyrolysis from metal salt precursors with ethylene glycol as the co-solvent and reducing agent. The morphology, crystallinity, and elemental distribution of particles were tunable by changing the reaction temperature, residence time, and quench gas flow rate. Hollow porous particles were fabricated with a higher Sn concentration on the particle surface when the furnace set point was 500°C, while solid particles with a lower surface Sn concentration were generated when the furnace set point was 1000°C. Particles with spherical morphologies were obtained at long residence time conditions (4.5 s). Cu-Sn binary particles with irregular structures (e.g., pores on the particle surface, fragmented spherical particles, and lamellar fragments) were formed at short residence time conditions (0.92 s). A possible spray pyrolysis mechanism was proposed that incorporates chemical reaction steps and structural progression. By this mechanism, the metal salts are believed to sequentially undergo hydrolysis to metal hydroxides, decomposition to metal oxides, reduction to metals, and finally diffusion of Sn into the Cu matrix to generate the Cu-Sn solid solution.

The Continuum of Northeast Pacific Marine Heatwaves and Their Relationship to the Tropical Pacific

Some questions remain concerning the record‐breaking 2013–2015 Northeast Pacific marine heatwave (MHW) event: was it exceptional or merely the most pronounced of a group of similar events, and was its intensity and multiyear duration driven by internal extratropical processes or did the tropics play an important role? By analyzing the statistical behavior of the historical MHWs within the ERSST.v3 data set over the 1950–2019 period, we find that Northeast Pacific MHWs occurred over a continuum of intensities and durations, suggesting that these events are a recurrent Pacific phenomenon. These statistics and corresponding composite evolution are dynamically reproduced by a large ensemble simulation of a Pacific Linear Inverse Model, thereby providing a greater range of MHW expressions than the short observational record alone. Consistent with the 2013–2015 event's evolution, we find that overall the tropics influence MHWs primarily by increasing their duration, while MHW intensity is related to the initial extratropical anomalies.
Effect of Subglottic Stenosis on Vocal Fold Vibration and Voice Production Using Fluid–Structure–Acoustics Interaction Simulation

An in-house 3D fluid–structure–acoustic interaction numerical solver was employed to investigate the effect of subglottic stenosis (SGS) on dynamics of glottal flow, vocal fold vibration and acoustics during voice production. The investigation focused on two SGS properties, including severity defined as the percentage of area reduction and location. The results show that SGS affects voice production only when its severity is beyond a threshold, which is at 75% for the glottal flow rate and acoustics, and at 90% for the vocal fold vibrations. Beyond the threshold, the flow rate, vocal fold vibration amplitude and vocal efficiency decrease rapidly with SGS severity, while the skewness quotient, vibration frequency, signal-to-noise ratio and vocal intensity decrease slightly, and the open quotient increases slightly. Changing the location of SGS shows no effect on the dynamics. Further analysis reveals that the effect of SGS on the dynamics is primarily due to its effect on the flow resistance in the entire airway, which is found to be related to the area ratio of glottis to SGS. Below the SGS severity of 75%, which corresponds to an area ratio of glottis to SGS of 0.1, changing the SGS severity only causes very small changes in the area ratio; therefore, its effect on the flow resistance and dynamics is very small. Beyond the SGS severity of 75%, increasing the SGS severity, leads to rapid increases of the area ratio, resulting in rapid changes in the flow resistance and dynamics.
Active fault tolerant control based on adaptive interval observer for uncertain systems with sensor faults

In this article, we present an active fault tolerant control scheme based on fault detection and isolation (FDI) for a class of uncertain systems subject to sensor faults. The FDI unit consists of a fault detection (FD) module and a fault isolation (FI) module, to determine when and where the sensor fault happens. It is noted that the FD module is based on a proposed adaptive interval observer where adaptive parameters instead of conservative uncertainty bounds are used, as a result, the sensitivity to faults is improved. When the FD module detects a fault, a compensation controller (CC) and an FI module are activated. The CC is designed to maintain some level of performance assuming all sensors are faulty. After the FI module determines the location of the fault, a reconfigured controller is activated to give improved performance with reduced conservatism. Importantly, the unmeasurable states and faulty output are approximated as a linear combination of their upper and lower bounds, and linear parameter are determined by adaptive laws. Finally, a simulation example is utilized to verify the effectiveness of the proposed scheme.
Lignin as an Active Biomaterial: A Review

Lignin is the second most naturally abundant biopolymer in the cell wall of lignocellulosic compound (15-35%) a fter cellulose. Lignin can be generated in massive amounts as by-products in biorefineries and pulp and paper industries through differing processes. Most lignin is utilized as generating energy and has always been treated as waste. Due to the high amount of phenolic compounds in lignin , it is considered as a potential material for various polymers, building blocks, and biomaterials production. Even though lignin can be utilized in the form of isolated lignin directly, the modification of lignin can increase the wide range of lignin applications. Lignin-based copolymers and modified lignin show better miscibility with another polymeric matrix, outstanding to the enhanced performance of such lignin -based polymer composites. T his article summarizes the properly updated information of lignin ’ s potential applications , such as bio - surfactant, active packaging, antimicrobial agent, and supercapacitor. Keywords: active packaging, antimicrobial agent, bio-surfactant, lignin, supercapacitor
Shoulder Tip Pain in Laparoscopic Cholecystectomy with Active vs Passive Evacuation of Pneumoperitoneum

Objective: The objective of the study was to compare the frequency of severity of shoulder tip pain after active (gas suctioning) and passive removal of pneumoperitoneum among patient undergoing laparoscopic cholecystectomy. Methods: This Observational comparative study was directed in general surgery department of DOW university hospital beginning from February 2016 to February 2017. Two hundred and six patients undergoing standard 4 port laparoscopic cholecystectomy were enrolled equally in either groups. The surgeon evacuated the abdomen by using a multiporous suction tube limiting the negative suction pressure to - 40 mmHg for 2-5 minutes under direct vision in active aspiration group, while in control group, CO2 was removed passively. Pain scores were recorded using visual analog score at 16 hours post-operatively by residents of surgery blinded to the study. Results: Mean VAS pain score at 16 hours in intervention group was much inferior than control group 1.00 ±2.09 vs. 3.06 ± 2.58 ( p < 0.001). Conclusion: Active aspiration of CO2 is an effective method that removes most if not all gas from the abdominal cavity. This will cause statistically significant decrease post-operative discomfort, pain and decrease need of rescue analgesics.

Role of Project Planning and Project Manager Competencies on Public Sector Project Success

Even though the world has progressed exponentially, the core reasons for the failure of many public sector projects remain the same, i.e., the poor planning and competency of a project manager. Therefore, it becomes essential even in the contemporary world to assess and evaluate a model that determines the effect of planning and the project manager’s competency on the success of public sector projects. Moreover, the present study aims to assess the role of project planning and the project manager’s competency in project success in the context of project management methodology defined by the Project Management Institute. In the current survey-based study, a sample of 260 project engineers, from the public sector organizations operating in Balochistan, that were engaged in projects was taken in order to understand the relationship between the constructs. Quantitative data were collected to address the proposed hypotheses using the partial least squares structural equation modeling technique. It was inferred from the findings that planning and competency have a significant positive impact on the success of public sector projects. Among the two, it was determined that planning for public sector projects has a greater role in the success of projects. Therefore, it is concluded based on the results of the study that in future, due consideration should be given to planning and the abilities of a project manager.
