Subwavelength Optical Engineering with Metasurface Waves

As artificial 2D materials made of subwavelength inclusions, metasurfaces bear exotic optical and electromagnetic properties not obtainable in naturally occurring materials. Based on unique wave behaviors such as short effective wavelength and local field enhancement that stem from the strongly local light–matter interaction, metasurfaces have the ability to overcome many tough problems faced by traditional optical engineers. Here, the history, basic principles, practical applications, and recent advancements of metasurfaces are reviewed in three main aspects: the breaking of the diffraction limit, the generalized laws of refraction and reflection, as well as the localized enhancement of light absorption. These landmark achievements could open a door for the optical engineering at the subwavelength scale, i.e., for Engineering Optics 2.0, and provide alternatives to traditional approaches based on bulky optical components. Moreover, multifunctional metasurfaces have also been introduced which could simultaneously achieve several different functionalities with a single device. As a concluding remark, the major challenges faced by this developing field are discussed.
Interobserver Reliability of the Kellgren-Lawrence Classification of Degenerative Knee Osteoarthritis among Resident Physicians from the University of the Philippines – Philippine General Hospital

Objectives. To determine the interobserver reliability of the Kellgren-Lawrence classification among selected residents from departments forming the University of the Philippines – Philippine General Hospital (UP-PGH) Osteoarthritis Multidisciplinary Clinic (OAMDC). Methods. From each department, 3 resident physicians (n = 9) were randomly chosen and tasked to categorize 20 knee anteroposterior and lateral radiographs into KLC grades. Inter-observer reliability was assessed using Fleiss’s kappa coefficient (κ). Results. Results show that there was 31.90% (κ = 0.3190 ± 0.0228, p-value < 0.05) agreement beyond chance in KLC grading of the radiograph series among all participating residents. Sub-group analyses of interobserver reliability in terms of departmental affiliation noted a range of agreement beyond chance in KLC grading, from 10.52% (κ = 0.1052 ± 0.0779, p-value < 0.05) to 56.38% (κ = 0.5638 ± 0.0844, p-value < 0.05). Conclusion. The findings reveal significant variability of agreement beyond chance in KLC grading, both within and among residents of UP-PGH OAMDC-participating clinical departments, which may reflect differences in training or competency and/or the documented limitations of the KLC system. Further investigation to improve diagnostic and severity assessment accuracy and uniformity in the institution is therefore warranted.
Quantitative Evaluation of Parafoveal Microvasculature Changes in Eyes with Exudative Circumscribed Choroidal Haemangioma : An Optical Coherence Tomography Angiography Study

Background: To quantitative evaluation of parafoveal microvasculature changes in eyes with exudative circumscribed choroidal haemangioma (CCH) compared with age- and gender-controlled healthy eyes.Methods: This was a cross-sectional, case-control study. 82 eyes of eighty-two subjects including 41 eyes of forty-one subjects in the exudative CCH group and 41 eyes of forty-one subjects in the age- and gender-controlled healthy eye group were enrolled in this study. Optical coherence tomography angiography (OCTA) was performed in each subject, and the capillary density (CD) of superficial plexus, deep capillary plexus, and the choriocapillaris as well as the area of foveal avascular zone (FAZ) were noted and analyzed between two groups.Results: The CD of the superficial plexus (44.51 ± 3.58 % vs 47.93 ± 2.94%) and deep plexus (47.75 ± 5.60% vs 52.66 ± 5.04%) of retina as well as the vessel density of choriocapillaris (54.42 ± 6.36% vs 61.83 ± 3.65%) significantly decreased in eyes with exudative CCH compared with age- and gender-controlled healthy eyes (all P < 0.001). Although we found that the FAZ areas in the exudative CCH group was larger than that of the healthy eye control group (0.30 ± 0.11mm2 vs 0.27 ± 0.87mm2), however, no statistical significance was found between two groups (P = 0.164). Conclusions: OCTA is a rapid, non-invasive, high-resolution procedure with which could monitor the parafoveal microvasculature changes in eyes with exudative CCH. We found that not only the CD of the superficial plexus and deep plexus but also the CD of choriocapillaris significantly decreased in eyes with exudative CCH compared with age- and gender-controlled healthy eye group.Trial registration: This study was registered on the https://www.clinicaltrials. gov (trial registration number: NCT04449900)
Non-stationary radar precipitation ensembles: a stochastic nested generator and orographic precipitation growth and decay trends

An ensemble of precipitation fields can be generated by multifractal simulation following the principle of linear generalized scale invariance. However, the statistical properties of real precipitation fields are usually not the outcome of a single global process, but depend on the spatial location (e.g. Lovejoy and Schertzer, 2013). Nerini el al. (2017) developed a non-stationary stochastic generator based on the Short-Space Fourier transform to account for the spatial heterogeneity of the statistical structure of precipitation fields. The stochastic generator is based on the local Fourier-filtering of a white noise field, where localization is achieved by applying a Hanning window on the precipitation field.
Experimental study of the diffusion-controlled corrosion of copper in the bottom of a jet stirred reactor

Jet stirred tank reactors are usually preferred to mechanically stirred tank reactors in the case of high pressure stirred tank reactors in order to avoid the mechanical problems inherent with mechanically agitated reactors. Owing to the impact force exercised by the fluid jet on the tank bottom, the tank bottom is subjected to severe corrosion. The aim of the present work is to address this problem using an accelerated system which simulates natural diffusioncontrolled corrosion of metals. Diffusion-controlled corrosion of a fixed copper disc, at the bottom of a cylindrical tank, under a single phase forced jet flow of acidified dichromate solution was investigated. Variables studied were: physical properties of the solution, solution velocity through different diameters of jet nozzle, distance between the jet outlet nozzle and the copper disc surface; and the effect of using a drag reducing polymer. An overall correlation was obtained: Sh = 0.579 Sc0.33 Re0.975 (h/d) 0.049 valid for 850 < Sc < 1322, 1852 < Re < 5000 and 0.3 < h/d < 1.2. Addition of polyethylene oxide as a drag reducing polymer was found to diminish the rate of corrosion under single phase forced jet flow by an amount depending on the operation conditions.
Fungal mycoflora dysbiosis in gastric cancer

Background: Bacterial infection is associated with gastric carcinogenesis. However, the relationship between nonbacterial components and gastric cancer (GC) has not been fully explored. We aimed to characterize the fungal mycobiome in GC.Results: We observed significant gastric fungal dysbiosis in GC. Principal component analysis revealed separate clusters for the GC and control groups, and Venn diagram analysis indicated that the GC group showed a lower OTU abundance than the control. At the genus level, the abundances of 15 fungal biomarkers distinguished the GC group from the control, of which Candida (p = 0.000246) and Alternaria (p = 0.00341) were enriched in GC, while Saitozyma (p = 0.002324) and Thermomyces (p = 0.009158) were decreased. Combining the results of Welch’s t test and Wilcoxon rank sum test, C. albicans was significantly elevated in GC. The species richness Krona pie chart further revealed that C. albicans occupied 22% and classified GC from the control with an area under the receiver operating curve (AUC) of 0.743. Random forest analysis also confirmed that C. albicans could serve as a biomarker with a certain degree of accuracy. Moreover, compared with that of the control, the alpha diversity index was significantly reduced in the GC group. The Jaccard distance index and the Bray abundance index of the PCoA clarified separate clusters between the GC and control groups at the species level (p = 0.00051). Adonis (PERMANOVA) analysis and ANOVA showed that there were significant differences in fungal structure among groups (p = 0.001). Finally, FUNGuild functional classification predicted that saprotrophs were the most abundant taxa in the GC group.Conclusions: This study revealed GC-associated mycobiome dysbiosis characterized by an altered fungal composition and ecology and demonstrated that C. albicans can be a fungal biomarker for GC. In addition, C. albicans may mediate GC by reducing the diversity and richness of fungi in the stomach, contributing to the pathogenesis of GC.

Classification of mammograms based on features extraction techniques using support vector machine

Now mammography is the most reliable method for early detection of breast cancer. The main objective of this research is to design a Computer-aided detection (CAD) system to help radiologists to provide a second view to diagnose mammograms. In the proposed system the medium filter and binary image with a global threshold will be applied to remove noise and small artifacts in the pre-processing phase. Secondly, In the segmentation stage, the Hybrid Bounding Box and Region Growing (HBBRG) algorithm will be used to remove the pectoral muscles, and then a geometric method has been utilized to cut the largest possible square that can be obtained from a mammogram which represents the ROI. In the feature extraction stage, three methods use to prepare a robust feature vector that represents a suitable input to the classification process are first Order (statistical features), Local Binary Patterns (LBP), and Gray-Level Co-Occurrence Matrix (GLCM). Finally, SVM has been applied in two-level to classify mammogram images in the first level to normal or abnormal, and then the classification of abnormal once in the second level to the benign or malignant image. The system was tested on the MAIS the Mammogram image analysis Society (MIAS) database, in addition to image from the Teaching Oncology Hospital, Medical City in Baghdad, where the results showed achieving an accuracy of 95.454% for the first level and 97.260% for the second level, also, the results of applying the proposed system to the MIAS database alone were achieving an accuracy of 93.105% for the first level and 94.59 for the second level.
Altered processing of communication signals in the subcortical auditory sensory pathway in autism

Autism spectrum disorder (ASD) is characterised by social communication difficulties. These difficulties have been mainly explained by cognitive, motivational, and emotional alterations in ASD. The communication difficulties could, however, also be associated with altered sensory processing of communication signals. Here, we assessed the functional integrity of auditory sensory pathway nuclei in ASD in three independent functional magnetic resonance imaging experiments. We focused on two aspects of auditory communication that are impaired in ASD: voice identity perception, and recognising speech‐in‐noise. We found reduced processing in adults with ASD as compared to typically developed control groups (pairwise matched on sex, age, and full‐scale IQ) in the central midbrain structure of the auditory pathway (inferior colliculus [IC]). The right IC responded less in the ASD as compared to the control group for voice identity, in contrast to speech recognition. The right IC also responded less in the ASD as compared to the control group when passively listening to vocal in contrast to non‐vocal sounds. Within the control group, the left and right IC responded more when recognising speech‐in‐noise as compared to when recognising speech without additional noise. In the ASD group, this was only the case in the left, but not the right IC. The results show that communication signal processing in ASD is associated with reduced subcortical sensory functioning in the midbrain. The results highlight the importance of considering sensory processing alterations in explaining communication difficulties, which are at the core of ASD.
Bulk-Heterojunction Thin-Film Solar Cells Utilizing Miscible Binary Donor Materials of Liquid Crystalline Phthalocyanine and its Analogue

Small-molecule bulk-heterojunction solar cells utilizing a binary-blended donor material composed of a liquid crystalline phthalocyanine and its analogue have been studied. The short-circuit current density (Jsc) and power conversion efficiency (PCE) of the solar cells utilizing the blended donor material with an optimized blend ratio reached 11.6 mA/cm2 and 4.8%, respectively, which were superior to those of organic solar cells utilizing each donor material. The improvement of Jsc and PCE has been discussed from the viewpoints of the crystal structure, optical and carrier transport properties of the blended donor material.
Gas sensing capability of spray deposited Al-doped ZnO thin films

Aluminium-doped zinc oxide thin films were deposited from zinc acetylacetonate and aluminium acetylacetonate at various aluminium concentrations and deposition temperatures by ultrasonic spray pyrolysis. The structural and morphological properties and elemental composition of these films were studied by X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray spectroscopy, respectively. The gas sensing properties were studied by a two-point probe in O2/99% N2 and H2/97% Ar at operating temperatures of 60, 80, and 100 °C. The films were composed of hexagonal wurtzite-type zinc oxide. The surface morphology of the films depends on the amount of aluminium doping. The hydrogen sensing capability of aluminiumdoped zinc oxide thin films deposited from 5 at% Al/Zn solution decreased from 11% to 5.5% as deposition temperature was increased from 280 to 400 °C, but the stability improved by an order of magnitude. The highest sensor response (8%) to 3 vol% H2 in Ar was observed at an operating temperature of 100 °C in the film deposited at a substrate temperature of 400 °C from the solution containing 2 at% Al/Zn. Aluminium doping above 2 at% Al/Zn in the solution reduced film resistance by up to two orders of magnitude and sensor response decreased to 3% at 100 °C. Response times as low as 3 s were observed when detecting hydrogen at operating temperatures 60–100 °C.
Antimicrobial properties and detection of crude extract derived from Magnolia garrettii inhabiting fungi

One hundred and fifty three isolates of endophytic and saprobic fungi were isolated from healthy-living and decayed-fallen branches of Montha Pa ( Magnolia garrettii (Craib) V.S. Kumar) in order to examine their antimicrobial potentials. Each fungal isolate was grown in five different culture media (F1, F3, F4, F5 and PDB) and incubated at room temperature for 6 days with shaking (130 rpm). Antimicrobial activity of each isolate was determined using paper disc diffusion assay of culture filtrate against Bacillus cereus , Candida albicans , Escherichia coli, Staphylococcus aureus and Pectobacterium carotovorum . The results showed that 19 culture filtrates exhibited an inhibitory activity towards at least one of the pathogens although none was found to suppress P. carotovorum . Further analysis of culture filtrate crude extract and mycelial crude extract from isolate MG5/2.4-1 and Chaetomium sp. 1MG9001 using thin layer chromatography showed the culture filtrate crude extract contained flavonoids, steroids, terpenoids, aldehydes, ketones, unsaturated compounds and alcohols, while the mycelial crude extracts was made largely of terpenoids, unsaturated compounds and alcohols. Evaluation of the two extracts against B. cereus , E. coli and S. aureus showed higher antimicrobial efficiency of the culture filtrates than that of the mycelial extracts and even greater than chloramphenicol in the case of S. aureus . Further studies on purification and characterization of the compounds in all crude extract are ongoing. Results from morphological and molecular studies suggested that Chaetomium sp. 1MG9001 is Chaetomium bostrychodes and the fungal isolate MG5/2.4-1 is the species belongs to the genus Diaporthe .
Evidence based pain assessment protocol for non-verbal patients

Purpose: Pain assessment practice in the nonverbal patient is incredibly challenging for the nurse and as such, evidence has shown that a protocolized approach to pain assessments has shown to be effective. Therefore, the purpose of this project was the education, implementation, and evaluation of an evidence based pain assessment protocol for the comprehensive assessment of pain in the nonverbal patient. Methodology: This Quality Improvement project included the Critical Care Pain Observation Tool (CPOT) as part of an evidence based pain assessment protocol. A three-month implementation phase utilizing the evidence based protocol was initiated following nursing education with a post implementation nursing survey to evaluate its effectiveness. Results: It was discovered that the majority of nurses rated the CPOT components as positive in pain assessment in the nonverbal patient, however, additional feedback showed that not all nurses understood how to utilize the tool. Implications for Practice: Effective pain assessment and management has been shown to decrease ICU length of stay, mechanical ventilation days, immobility, and negative hospital outcomes, however, based on nursing feedback, additional education and expert training may be beneficial for practice.
