Fabrication and characterization of a dynamically flat high resolution micro-scanner

We present an ultra flat high frequency micro-scanner for high resolution laser projection applications. The scanner is fabricated in silicon-on-insulator wafers with a 30? m thick device layer. A backside island is constructed behind the mirror plate to improve the rigidity. The backside island is done with a deep reactive ion etching (DRIE)? tetramethylammonium hydroxide (TMAH) combination process to achieve a height of 86? m with good uniformity (4% within-wafer non-uniformity). The dynamic deformation is measured with a stroboscopic interferometer. The 1? mm diameter mirror plate has a root-mean-square deformation of less than 27? nm if operated at 30.84? kHz and a mechanical scan angle of ? 10? The dynamic flatness performance of the device exceeds the optical quality requirement of <? /10 deformation. The modulation transfer function of the scanner is calculated to demonstrate the resolution improvement from a scanner without backside reinforcement. With a diameter? scan angle product of 10 and a good dynamic flatness, the scanner is capable of performing the horizontal scanning (800? pixels) for an SVGA quality laser projection display.
VERY HIGH BREAKDOWN VOLTAGE AND LARGE TRANSCONDUCTANCE REALIZED ON GAN HETEROJUNCTION FIELD EFFECT TRANSISTORS

We report record high breakdown voltages up to 340 and 230 V realized on unintentionally doped (1.5 μm gate length) and Si doped (1 μm gate length) AlGaN/GaN modulation doped field effect transistors (MODFETs), respectively. The devices also have large transconductances up to 140 mS/mm and a full channel current of 150–400 mA/mm. The Si doped MODFET sample demonstrated a very high room temperature mobility of 1500 cm2/Vs. With these specifications, GaN field effect transistors as microwave power devices are practical.
Optimization of the growth conditions through response surface methodology and metabolomics for maximizing the auxin production by Pantoea agglomerans C1

Introduction The fermentative production of auxin/indole 3-acetate (IAA) using selected Pantoea agglomerans strains can be a promising approach to developing novel plant biostimulants for agriculture use. Methods By integrating metabolomics and fermentation technologies, this study aimed to define the optimal culture conditions to obtain auxin/IAA-enriched plant postbiotics using P. agglomerans strain C1. Metabolomics analysis allowed us to demonstrate that the production of a selected. Results and discussion: Array of compounds with plant growth-promoting- (IAA and hypoxanthine) and biocontrol activity (NS-5, cyclohexanone, homo-L-arginine, methyl hexadecenoic acid, and indole-3-carbinol) can be stimulated by cultivating this strain on minimal saline medium amended with sucrose as a carbon source. We applied a three-level-two-factor central composite design (CCD) based response surface methodology (RSM) to explore the impact of the independent variables (rotation speed and medium liquid-to-flask volume ratio) on the production of IAA and IAA precursors. The ANOVA component of the CCD indicated that all the process-independent variables investigated significantly impacted the auxin/IAA production by P. agglomerans strain C1. The optimum values of variables were a rotation speed of 180 rpm and a medium liquid-to-flask volume ratio of 1:10. Using the CCD-RSM method, we obtained a maximum indole auxin production of 208.3 ± 0.4 mg IAAequ/L, which was a 40% increase compared to the growth conditions used in previous studies. Targeted metabolomics allowed us to demonstrate that the IAA product selectivity and the accumulation of the IAA precursor indole-3-pyruvic acid were significantly affected by the increase in the rotation speed and the aeration efficiency.
Learning global spatial information for multi-view object-centric models

Recently, several studies have been working on multi-view object-centric models, which predict unobserved views of a scene and infer object-centric representations from several observation views. In general, multi-object scenes can be uniquely determined if both the properties of individual objects and the spatial arrangement of objects are specified; however, existing multi-view object-centric models only infer object-level representations and lack spatial information. This insufficient modeling can degrade novel-view synthesis quality and make it difficult to generate novel scenes. We can model both spatial information and object representations by introducing a hierarchical probabilistic model, which contains a global latent variable on top of object-level latent variables. However, how to execute inference and training with that hierarchical multi-view object-centric model is unclear. Therefore, we introduce several crucial components which help inference and training with the proposed model. We show that the proposed method achieves good inference quality and can also generate novel scenes properly. GRAPHICAL ABSTRACT
Exploring feelings of belonging and membership of CUNY noncitizen students

Abstract For young immigrants who are also college students, the sense of belonging impacts not only their integration in the host society, but their school community as well. Group membership has been associated with the sense of belonging, which in turn impacts the sense of self. Self-esteem, defined as a feeling of self-worth and self-respect, is considered to be fundamental to psychological well-being. This study explores feelings of belonging and membership of noncitizen students and the impact on their mental well-being. Data were drawn from 137 participants across multiple undergraduate campuses across the City University of New York (CUNY) system. Initial findings of the CUNY Belonging Study indicate that, consistent with existing research, noncitizen students’ immigration status impacts their ability to form a sense of belonging, and belonging and membership is related to the level of institutional support they receive.
Imaging the polariton relaxation bottleneck in strongly coupled organic semiconductor microcavities

We use angular-resolved photoluminescence excitation spectroscopy to probe energy relaxation towards the lowest lying states (k∥=0) on the lower polariton branch (LPB) of two different strong-coupled J-aggregate organic semiconductor microcavities. We find that states along the upper polariton branch (UPB) are able to undergo efficient relaxation to populate states around k∥=0 on the LPB; a process that occurs through the rapid relaxation of UPB polaritons to the exciton reservoir. In contrast, LPB states having a photon fraction >0.5 are not apparently able to undergo further relaxation towards k∥=0, constituting an effective relaxation bottleneck.
Differences in Soil Microbial Communities between Healthy and Diseased Lycium barbarum cv. Ningqi-5 Plants with Root Rot

For a long time, the development of the Lycium barbarum industry has been seriously restricted by root rot disease. In general, the occurrence of plant root rot is considered to be closely related to the composition and diversity of the soil microbial community. It is critical to understand the relationship between the occurrence of root rot in L. barbarum and the soil microbial composition. In this study, samples of the rhizosphere, rhizoplane, and root zone were collected from diseased and healthy plants. The V3–V4 region of bacterial 16S rDNA and the fungal ITS1 fragment of the collected samples were sequenced using Illumina MiSeq high-throughput sequencing technology. The sequencing results were first quality controlled and then aligned with the relevant databases for annotation and analysis. The richness of fungal communities in the rhizoplane and root zone of the healthy plants was significantly higher than that of the diseased plants (p < 0.05), and the community evenness and diversity of all the rhizoplane samples were significantly different from those of the rhizosphere and root zone. The richness of the bacterial communities in the rhizosphere and root zone of healthy plants was significantly greater than those of diseased plants (p < 0.05). The community composition of the rhizoplane was quite different from the other parts. The abundance of Fusarium in the rhizoplane and rhizosphere soil of diseased plants was higher than that in the corresponding parts of healthy plants. The abundances of Mortierella and Ilyonectria in the three parts of the healthy plants were correspondingly higher than those in the three parts of the diseased plants, and Plectosphaerella was the most abundant in the rhizoplane of diseased plants. There was little difference in the composition of the dominant bacteria at the phylum and genus levels between healthy plants and diseased plants, but the abundances of these dominant bacteria were different between healthy and diseased plants. Functional prediction showed that the bacterial community had the largest proportion of functional abundance belonging to metabolism. The functional abundances of the diseased plants, such as metabolism and genetic information processing, were lower than those of the healthy plants. The fungal community function prediction showed that the Animal Pathogen-Endophyte-Lichen Parasite-Plant Pathogen-Soil Saprotroph-Wood Saprotroph group had the largest functional abundance, and the corresponding fungi were Fusarium. In this study, we mainly discussed the differences in the soil microbial communities and their functions between the healthy and diseased L. barbarum cv. Ningqi-5, and predicted the functional composition of the microbial community, which is of great significance to understanding the root rot of L. barbarum.
Digital assessments of soil organic carbon storage using digital maps provided by static and dynamic environmental covariates

Understanding the vertical and lateral distribution of soil organic carbon (SOC) and soil organic carbon density (SOCD) is indispensable for soil use and environmental management because of their vital role in soil quality assessments. Primarily, they are needed in calculating soil organic carbon storage (SOCS). The objective of this research was to provide digital maps of SOC and SOCD variation as well as their uncertainties at multiple standardized depths (H1: 0–5, H2: 5–15, H3: 15–30, H4: 30–60 and H5: 60–100 cm) using a parsimonious model with optimized terrain‐related attributes and satellite‐derived data. SOCS were evaluated at soil subgroup levels. An area of about 808 km2 with varying elevation, plant cover and lithology from the Miandoab region, West Azerbaijan Province, Iran was selected as a case study area. A total of 386 soil samples were collected from 104 profiles comprising various soil genetic horizons. A continuous spline function was then fitted to the target properties in advance of creating a dataset at five standard depth intervals (following the GlobalSoilMap project). These were then grouped into three classes including top (H1), middle (H2, H3 and H4) and bottom (H5) depths to ease interpretation. Static and dynamic covariates (30‐m resolution) were derived from a digital elevation model (DEM) and a suite of Landsat‐8 spectral imageries, respectively. Four candidate models including stepwise multiple linear regression (SMLR), random forest (RF), cubist (CU) and extreme gradient boosting (XGBoost) Tree were tested in this study. Finally, the digital maps at 30‐m resolution of SOC and SOCD and their uncertainties were prepared using the best‐fit model and the bootstrapping method, respectively. Four soil subgroups (Gypsic Haploxerepts, Typic Calcixerepts, Typic Haploxerepts and Xeric Haplocalcids) were identified across the study area. The covariates had variable contributions on the evaluated models. The XGBoost Tree model generally outperformed other models for prediction of SOC and SOCD (R2 = 0.60, on average). Regardless of soil subgroups, the uncertainty analysis showed that the SOCD map had a low prediction interval range value indicating high accuracy. Additionally, the highest SOCS and SOCD was observed at the top followed by middle and bottom depths in the study area. All subgroups exhibited a decreasing trend of SOCD with increasing depth. A similar trend was also observed for SOCS. The highest SOCD (on average) was observed in Gypsic Haploxerepts (4.71 kg C/m2) followed by Typic Calcixerepts (4.46 kg C/m2), Typic Haploxerepts (4.45 kg C/m2) and Xeric Haplocalcids (4.40 kg C/m2). Overall, the SOCS normalized by area within soil order boundaries was greater in Inceptisols than Aridisols across the study area. The findings of this study provide critical information for sustainable management of soil resources in the area for agricultural production and environmental health in the Miandoab region of Iran.
Emotion regulation and mental health among professionals of long-term care institutions for older adults: the mediating role of work engagement

BACKGROUND This study examined whether work engagement mediated the association between emotion regulation and mental health of professionals working in long-term care institutions for older adults in Brazil. PARTICIPANTS AND PROCEDURE A cross-sectional study with a total of 104 professionals working in 13 long-term care facilities for the elderly in Brazil was conducted. Emotion regulation (expressive suppression and cognitive reappraisal), work engagement (vigor, dedication, and absorption), and mental health (depression, anxiety, and stress) were measured using self-report scales. Multiple mediation models were used to test the mediating role of engagement. RESULTS Expressive suppression was associated with more vigor, which in turn was associated with less anxiety and stress; cognitive reappraisal was associated with more vigor, which in turn was associated with less anxiety and stress. No indirect effects were found for depression. CONCLUSIONS Expressive suppression and cognitive reappraisal strategies to regulate emotions seem to be associated with more vigor in terms of resilience and persistence to deal with work demands in these professionals. These results seem to suggest that workers who are more capable of regulating their emotions (using both expressive suppression and cognitive reappraisal in a flexible way according to work demands) are more likely to be resilient, invest in their profession, and be persistent in the face of difficulties. This, in turn, contributes to protecting them from experiencing anxiety and stress.

Virtual Hartmann-shack image applied in laser beam wavefront correction and numerical simulation method

In adaptive optics,Hartmann-shack wavefront sensor and image acquired from camera has been widely used to detect incident wavefront and the application of laser wavefront correction. A numerical simulation method of generating high resolution virtual camera image, which is based on Fourier optics and realized by FFT algorithm, is mentioned in this paper. In the condition of incident laser beam wavefront with only tilt phase aberration, calculating deviation of centroid offset between the result from virtual camera image and theoretical value, is compared to verify the accuracy of this numerical simulation method and virtual Hartmann-shack image generation model.
Degree of $L_p$ Approximation by Monotone Splines

Using elementary techniques, we obtain Jackson type estimates for the approximation of monotone nondecreasing functions by monotone nondecreasing splines with equally spaced knots in $L_p [0,1],\, 1 \leqq p \leqq \infty $. Our method, which works for all p, is different from that of De Vore.
Finite element simulation of three‐dimensional free‐surface flow problems with dynamic contact lines

An arbitrary Lagrangian–Eulerian (ALE) finite element method is described for the solution of three‐dimensional free‐surface flow problems. The focus of this work is on extending the algorithm to include a dynamic contact line model allowing the fluid free surface, in the steady case, to form a prespecified static contact angle with a solid boundary and, in the transient case, to move along the solid boundary. This widens the applicability of the algorithm to important industrial applications such as forced spreading of fluids and gravity‐driven flow on inclined surfaces.

Assessing Alternative Pre-Treatment Methods to Promote Essential Oil Fixation into Cotton and Polyethylene Terephthalate Fiber: A Comparative Study

This study aims to develop a new refreshing feeling, ecological, and antimicrobial fabrics for medicinal applications. The geranium essential oils (GEO) are incorporated into polyester and cotton fabrics by different methods, such as ultrasound, diffusion, and padding. The effect of solvent, nature of fibers, and treatment processes were evaluated via the thermal properties, the color strength, the odor intensity, the wash fastness, and the antibacterial activities of the fabrics. It was found that the ultrasound method was the most efficient process for incorporation of GEO. Ultrasound produced a great effect on the color strength of the treated fabrics, suggesting the absorption of geranium oil in fiber surface. The color strength (K/S) increased from 0.22 for the original fabric to 0.91 for the modified counterpart. In addition, the treated fibers showed appreciable antibacterial capacity against Gram-positive (Staphylococcus epidermidis) and Gram-negative (Escherichia coli) bacteria strains. Moreover, the ultrasound process can effectively guarantee the stability of geranium oil in fabrics without decreasing the significant odor intensity and antibacterial character. Based on the interesting properties like ecofriendliness, reusability, antibacterial, and a refreshing feeling, it was suggested that textile impregnated with geranium essential oil might be used as a potential material in cosmetic applications.

Aerodynamic computations for the X-33 vehicle were performed using two  nite volume, Navier–Stokes solvers and an inviscid Euler code. Computations were made for a range of wind-tunnel test conditions from Mach 4.63 to 10.0 with angles of attack from 10 to 48 deg and body  ap de ections of 0,+10, and+20 deg. Additionalcomputationswere performed over a parametric range of freestream conditions with Mach numbers of 4–10 and angles of attack of 10–50 deg. Computational results and comparisons with wind-tunnel aerodynamic data are presented.
Perceived Occupational Noise Exposure and Depression in Young Finnish Adults

We investigated the association between perceived occupational noise exposure and depressive symptoms in young Finnish adults and whether noise sensitivity moderates this association. This study was based on an ongoing longitudinal twin study. We included those who had been working daily (n = 521) or weekly (n = 245) during the past 12 months (mean age 22.4, SD 0.7, 53% female). We asked about occupational noise exposure at age 22 and assessed depressive symptoms using the General Behavior Inventory (GBI) at age 17 and 22. Noise sensitivity and covariates were used in linear regression models. Perceived daily occupational noise exposure was associated, as a statistically independent main effect with depressive symptoms at age 22 (beta 1.19; 95% CI 0.09, 2.29) among all, and separately for females (beta 2.22; 95% CI 0.34, 4.09) but not males (beta 0.22; 95% CI −1.08, 1.52). Noise sensitivity was independently associated with depressive symptoms among all (beta 1.35; 95% CI 0.54, 2.17), and separately for males (beta 1.96; 95% CI 0.68, 3.24) but not females (beta 1.05; 95 % CI −0.04, 2.13). Noise sensitivity was independent of perceived occupational noise exposure. Pre-existing depressive symptoms at age 17 were predictive of perceived occupational noise exposure, suggesting complex interactions of noise and depression.
Performance evaluation of TCP over OBS networks with multiple TCP input flows

In this paper, TCP performance over OBS networks with multiple TCP input flows is evaluated. A new burst assembly method is put forward to improve TCP performance on OBS networks. Normally, TCP packets are assembled by only one assembly queue, increasing the number of the burst assembly queues will affect the TCP performance. Simulation results show that when using time and burst-length threshold, according to burst-length threshold, different number of burst assembly queues should be chosen to get better TCP performance.
Retinal vein changes after treatment with aflibercept and PRP in high-risk proliferative diabetic retinopathy

Objective The objective of the study was to investigate the effectiveness of aflibercept and panretinal photocoagulation (PRP) in the treatment of proliferative diabetic retinopathy (PDR). Methods A retrospective analysis was performed on 59 patients (59 eyes) with high-risk PDR who were treated with aflibercept and PRP between January 2018 and December 2019. The best corrected visual acuity (BCVA), central foveal thickness (CFT), and retinal vein diameter post-treatment were compared to those before the treatment. Results The best corrected visual acuity (BCVA) at 6 months (0.49 ± 0.14 logMAR), 12 months (0.54 ± 0.15 logMAR), 18 months (0.48 ± 0.15 logMAR), and 24 months (0.51 ± 0.15 logMAR) post-treatment were superior to the pre-treatment measurement (0.65 ± 0.18 logMAR). The central foveal thickness (CFT) at 6 months (310.67 ± 52.53 μm), 12 months (295.98 ± 45.65 μm), 18 months (282.56 ± 43.57 μm), and 24 months (281.53 ± 51.16 μm) post-treatment were lower than the pre-treatment measurement (456.53 ± 51.49 μm); the retinal vein diameter at 12 months (310.13 ± 24.60 μm), 18 months (309.50 ± 31.58 μm), and 24 months (317.00 ± 27.54 μm) post-treatment were lower than the pre-treatment measurement (361.81 ± 30.26 μm). Conclusion Aflibercept intravitreal injection and panretinal photocoagulation may morphologically reverse retinal vein diameter and venous beading in high-risk proliferative diabetic retinopathy.
Radio identifications of UGC galaxies - starbursts and monsters

New and previously published observational data on galaxies with declination less than +82 deg from the Uppsala General Catalog (Nilson, 1973) are compiled in extensive tables and characterized in detail. Optical positions are confirmed by measurement of Palomar Sky Survey O prints, and radio identifications for 176 galaxies are made on the basis of 1.4-GHz Green Bank sky maps or 1.49-GHz observations obtained with the C configuration of the VLA in November-December 1986; contour maps based on the latter observations are provided. Radio-selected and IR-selected galaxy populations are found to be similar (and distinct from optically selected populations), and three radio/IR criteria are developed to distinguish galaxies powered by starbursts from those with supermassive black holes or other monster energy sources. 197 references.
THIS PAGE IS NOT PART OF THE THESIS, BUT SHOULD BE TURNED IN TO THE PROOFREADER!

by Feride Tığlay In this work, we study the periodic Cauchy problem for two nonlinear evolution equations: The modified Hunter-Saxton equation and the Euler-Poisson equation. Modifying the techniques developed for Euler equations of hydrodynamics, we prove local well-posedness results in Sobolev spaces. We also investigate the analytic regularity of solutions to these equations and prove Cauchy-Kowalevski type results. Finally we describe the Hamiltonian structure of the Euler-Poisson equation on a semidirect product space.
