Transitioning to Independent Nursing Practice during COVID-19: A Mixed Methods Study

The COVID-19 pandemic presented challenges to onboard and support new graduate nurses (NGNs). This study sought to explore the perceptions of nurses entering clinical practice during the COVID-19 pandemic. Using mixed methods, we investigated the experiences of NGNs entering the field during the pandemic and how a nurse residency program (NRP) adapted to meet their needs. Newly graduated nurses entering practice in November 2019 described their transition through nurse experience surveys and focus group discussions. Results from the quantitative data reported on compassion satisfaction, burnout, and exposure to secondary traumatic stress. The qualitative data mirrored these findings with the discovery of the following five themes: transitioning through an NRP, impact to nursing care, value of coworkers, coping, and professional growth. These findings illustrate the need to better support future practice transitions in times of disruption and change.
The Latest Evidence of Erythropoietin in the Treatment of Glaucoma

Erythropoietin (EPO) is a circulating hormone conventionally considered to be responsible for erythropoiesis. In addition to facilitating red blood cell production, EPO has pluripotent potential, such as for cognition improvement, neurogenesis, and anti-fibrotic, anti-apoptotic, anti-oxidative, and anti-inflammatory effects. In human retinal tissues, EPO receptors (EPORs) are expressed in the photoreceptor cells, retinal pigment epithelium, and retinal ganglion cell layer. Studies have suggested its potential therapeutic effects in many neurodegenerative diseases, including glaucoma. In this review, we discuss the correlation between glaucoma and EPO, physiology and potential neuroprotective function of the EPO/EPOR system, and latest evidence for the treatment of glaucoma with EPO.
Hydrostatic compression of four corundum‐type compounds: α‐Al2O3, V2O3, Cr2O3, and α‐Fe2O3

Accurate x‐ray diffraction experiments for hydrostatic compression of corundum α‐Al2O3 and transition‐metal sesquioxides with the corundum structure, V2O3, Cr2O3, and α‐Fe2O3, were performed using a cubic‐anvil type of high‐pressure apparatus at room temperature up to about 120 kbar. An isotropic compression of the unit cell was found in α‐Al2O3 and Cr2O3. In V2O3 and α‐Fe2O3, anisotropic behaviors of compression were observed: The ratio c/a in the hexagonal cell increases in V2O3 and decreases in α‐Fe2O3 with increasing pressure. The isothermal bulk modulus KT=1.75±0.03 Mbar of V2O3 is unusually small among the studied compounds with the corundum structure. Values of 2.39±0.04 Mbar and 2.31±0.05 Mbar were calculated for KT of α‐Al2O3 and Cr2O3, and a value of 2.31±0.10 Mbar for KT of α‐Fe2O3 in the pressure range below 30 kbar.
The Operational Significance of the Continuum Hypothesis in the Theory of Water Movement Through Soils and Aquifers

The operational meaning of the representative elementary volume (REV) concept, on which current foundational theories of water movement through porous media are based, is analyzed critically. It is concluded that the REV concept as applied to real porous media is both unnecessarily restrictive and experimentally unverifiable. In its place a relativist concept is proposed in which macroscopic physical variables are defined as convolution products of microscopic properties of a porous medium with weighting functions that represent the appropriate measuring instruments. The effects of resolution and precision differences among experimental measuring devices, now recognized as critical in the assessment of spatial variability in the properties of soils and aquifers, can be incorporated naturally within the relativist concept but are excluded a priori in the REV concept. The relativist point of view, unlike the REV concept, has a clear operational meaning and, in principle, extends theoretical validity to all local measurements made on porous media. It is sufficient mathematically to derive conventional macroscopic balance equations for mass and linear momentum as well as a differential equation for the isothermal transport of water through an unsaturated, anisotropic, deformable soil or aquifer.
PRECISE ESTIMATES OF THE SYNTHETIC SPECTRAL DISTANCES TO DA WHITE DWARFS

Using recent photometric calibrations, we develop greatly improved distance estimates for DA white dwarfs using multi-band synthetic photometry based on spectroscopic temperatures and gravities. Very good correlations are shown to exist between our spectroscopically based photometric distance estimates and those derived from trigonometric parallaxes. We investigate the uncertainties involved in our distance estimates, as well as discuss the circumstances where such techniques are most likely to fail. We apply our techniques to the large sample of Sloan Digital Sky Survey DA white dwarfs where automated fitting of H i Balmer profiles yields spectrometric temperatures and gravities. We determine simple empirical corrections to these temperatures and gravities with respect to published slit spectroscopy. After applying these Teff–log g corrections as well as appropriate interstellar extinction corrections, where necessary, we derive spectroscopically based photometric distances for 7062 DA stars from this sample.
Surface Modifications of High-Performance Polymer Polyetheretherketone (PEEK) to Improve Its Biological Performance in Dentistry

This comprehensive review focuses on polyetheretherketone (PEEK), a synthetic thermoplastic polymer, for applications in dentistry. As a high-performance polymer, PEEK is intrinsically robust yet biocompatible, making it an ideal substitute for titanium—the current gold standard in dentistry. PEEK, however, is also inert due to its low surface energy and brings challenges when employed in dentistry. Inert PEEK often falls short of achieving a few critical requirements of clinical dental materials, such as adhesiveness, osseoconductivity, antibacterial properties, and resistance to tribocorrosion. This study aims to review these properties and explore the various surface modification strategies that enhance the performance of PEEK. Literatures searches were conducted on Google Scholar, Research Gate, and PubMed databases using PEEK, polyetheretherketone, osseointegration of PEEK, PEEK in dentistry, tribology of PEEK, surface modifications, dental applications, bonding strength, surface topography, adhesive in dentistry, and dental implant as keywords. Literature on the topics of surface modification to increase adhesiveness, tribology, and osseointegration of PEEK were included in the review. The unavailability of full texts was considered when excluding literature. Surface modifications via chemical strategies (such as sulfonation, plasma treatment, UV treatment, surface coating, surface polymerization, etc.) and/or physical approaches (such as sandblasting, laser treatment, accelerated neutral atom beam, layer-by-layer assembly, particle leaching, etc.) discussed in the literature are summarized and compared. Further, approaches such as the incorporation of bioactive materials, e.g., osteogenic agents, antibacterial agents, etc., to enhance the abovementioned desired properties are explored. This review presents surface modification as a critical and essential approach to enhance the biological performance of PEEK in dentistry by retaining its mechanical robustness.
Critical Phenomena in the Phase Diagrams of QCD-like Theories

QCD is the well-established theory of strong interactions but of such a complex nature that outstanding open questions remain even after almost 40 years since its discovery. In this thesis we concentrate on aspects of finite density QCD and the deconfinement transition, which we study, however, not in QCD itself but in QCD-like theories that are obtained by deformations of the QCD Lagrangian. In particular, we study effective models for 2-color QCD, adjoint QCD and QCD with isospin chemical potential as the three prototypical examples for QCD-like theories without a fermion sign problem and investigate their corresponding phase diagrams. One main tool in our analysis is the Functional Renormalization Group, which allows to consistently include quantum and thermal fluctuations and to study critical phenomena. A particular focus lies on two-color QCD, which provides a transparent demonstration of the impact of baryonic degrees of freedom: without them its phase diagram resembles that of corresponding 3-color model calculations including a critical endpoint which vanishes, however, inside the diquark condensation phase once one properly includes the diquarks as lightest baryonic degrees of freedom. Interesting relations to effective models for the BEC-BCS crossover in (non-relativistic) ultracold atomic gases arise, which are most transparently demonstrated in the comparison between QCD with isospin chemical potential and imbalanced Fermi gases. In the second part we study the deconfinement transition in 2+1 dimensional pure SU(N) lattice gauge theories using universality methods.
Broad-Band Spectra Study of 213 VSOP 5-GHz Survey Sources

We present a statistical and model study of 1-22 GHz spectra and 5-GHz interpolated data for 213 of 230 sources with declinations 5 > —30°, selected for survey observations with the HALCA space radio telescope. The spectra of two subsamples were specially surveyed and monitored in 1997-2000 as a ground spectra support for the space VLBI survey in the framework of the VSOP Survey Programme. Every 1-22 GHz spectrum was measured with the RATAN-600 radio telescope at six wavelengths of 1.4, 2.7, 3.9, 7.7, 13, and 31 cm over a period of a few minutes (ten minutes or more near the pole). (25-30)% of the sources studied are outside of the VSOP selection criteria in 1997-2000 because of the variability of the VSOP sources, which were compiled from catalogs spanning a period between 1985 and 1996. About 60% of 186 VSOP/HALCA sources, monitored in 8 epochs, have amplitudes of variability greater than ±10% at 5 GHz over the three-year period. 45 new strong of 660 additionally surveyed sources have been found and can be added to the HALCA sample. 26 of 45 sources are new for the full VSOP list. Almost all VSOP sources are suggested to have continuous jets at milliarcsecond scales. This conclusion is supported by an analysis of the individual spectra for 213 objects, their mean statistical shape in the local frame, and the long-term variable spectra for 25 objects. Model and statistical analyses suggest a common physical origin of the radio sources of various types in the studied samples and in the majority of VSOP survey sources.
An Analysis of Consumer Willingness to Pay for Sorghum-Pigeon Pea Flakes: A Case of Makueni and Busia Counties, Kenya

Purpose: The study seeks to determine the level of awareness and the highest amount consumers were willing to pay by positioning the novel product ready-to eat-cereals for breakfast Sorghum-pigeon pea processed from locally grown crop. Methodology: Contingent Valuation Method (CVM) to assess consumer willingness to pay (WTP) for sorghum-pigeon pea flakes, which are Ready-to-Eat Cereals (RTEC). Three-stage sampling technique was used in selection of the two counties, and from each county three market places was identified. Glen sample size formula was used to obtain the total number of respondents, whereby a well semi-structured dichotomous questionnaire was used on 223 consumers from Makueni and Busia counties in Kenya. Double bounded logit model was employed in determining consumers' willingness to pay (WTP) for SPPF. Findings: Results from the WTP assessment showed that consumers in both counties were willing to pay for the Sorghum-Pigeon Pea Flakes. The average WTP value in Busia and Makueni Counties was 140 and 136 Kenya Shillings, respectively. Further, nearly half of the respondents in both counties were aware of the ready-to-eat breakfast cereal SPPF for nutritional improvement. According to the findings of the double-bounded logit regression, being male, marital status, awareness of SPPF, and living in Busia County all positively influenced WTP for SPP. Having formal employment and household expenditure, on the other hand, had a negative impact on the WTP for SPPF. Recommendations: The study recommends nutritional training to raise awareness of the benefits of consuming SPP. Furthermore, policies should focus on raising awareness of the nutritional benefits of SPPF among families, particularly those in Makueni.
Clinical Characteristics and Gene Mutations of Two Families with MODY 3 in Inner Mongolia

Objective This study aimed to analyze the clinical characteristics and gene mutations of two families with maturity-onset diabetes of the young 3 (MODY 3) in Inner Mongolia. Methods Fifty-three patients in Inner Mongolia suspected of having MODY 3 were enrolled in this study according to clinical manifestations. Blood samples were collected, and all exons of the HNF1α gene were analyzed; the second-generation DNA of the splicing regions of the gene was determined by direct sequencing. Results In Family 1, the proband, mother, and uncle all carried the missense heterozygous mutation on exon 2 of the HNF1α gene (c.512G>A, p.Arg171Gln), and both the proband and uncle had MODY 3. In Family 2, the proband, grandfather, father, uncle I, and uncle II all carried a missense mutation on exon 2 (c.391C>t, p.Arg131Trp), and all had MODY 3. The blood glucose control in these patients was stable while they were being treated with oral sulfonylurea hypoglycemic drugs alone or with insulin. Uncle II had serious macrovascular and microvascular complications. Conclusion Maturity-onset diabetes of the young 3 gene mutations (c.512G>A, p.Arg171Gln) and (c.391C>T, p.Arg131Trp) may be the main pathogenic genes of the two families with MODY 3. The two gene mutations found in this study have not been reported previously in China.
Stimulated interdiffusion and optical recording in amorphous chalcogenide nanomultilayers

Investigations of optical recording processes in amorphous chalcogenide layers were extended to the compositionally modulated amorphous nanomultilayers made of different pairs of chalcogenide glasses from As-S(Se) systems or pairs of chalcogenide glasses and metals, dielectrics. This type of recording is connected to the light-stimulated mass transport across the interfaces, possible phase transformations and correlated changes of optical parameters (absorption, refraction, reflection). The interconnections between the compositional modulation at nano-scale dimensions (~3-10 nm) and possible improvement of recording parameters (the rate and degree of optical bleaching, darkening, local changes of the thickness and of the refractive index, spatial resolution) were established.
Information in Streetscapes - Research on Visual Perception Information Quantity of Street Space Based on Information Entropy and Machine Learning

Urban street space is a critical reflection of a city’s vitality and image and a critical component of urban planning. While visual perceptual information about an urban street space can reflect the composition of place elements and spatial relationships, it lacks a unified and comprehensive quantification system. It is frequently presented in the form of element proportions without accounting for realistic factors, such as occlusion, light and shadow, and materials, making it difficult for the data to accurately describe the complex information found in real scenes. The conclusions of related studies are insufficiently focused to serve as a guide for designing solutions, remaining merely theoretical paradigms. As such, this study employed semantic segmentation and information entropy models to generate four visual perceptual information quantity (VPIQ) measures of street space: (1) form; (2) line; (3) texture; and (4) color. Then, at the macro level, the streetscape coefficient of variation (SCV) and K-means cluster entropy (HCK) were proposed to quantify the street’s spatial variation characteristics based on VPIQ. Additionally, we used geographically weighted regression (GWR) to investigate the relationship between VPIQ and street elements at the meso level as well as its practical application. This method can accurately and objectively describe and detect the current state of street spaces, assisting urban planners and decision-makers in making decisions about planning policies, urban regeneration schemes, and how to manage the street environment.
Systematic literature review on the utilization of theoretical underpinnings in virtual exchange research

Virtual Exchange (VE) research is a subset of the technology enhanced learning field that has grown exponentially in the last decade. A critical step in the growth of an emerging academic field is to reflect on past research to understand what has been done well and what can be improved. This Systematic Literature Review (SLR) contributes to this reflective process by examining if a common criticism of technology enhanced learning research in Higher Education (HE) – the under-utilization of theoretical underpinnings in research – extends to the niche field of VE research. Using a qualitative meta-synthesis methodology, 42 qualitative and mixed method articles on VE were analyzed for theoretical underpinning usage, application, and advancement. Almost half of the articles explicitly used theoretical underpinnings in the conceptualization, data collection and analysis, and discussion of results. About a third of the articles explicitly used theoretical underpinnings in the design of the VE, but not necessarily in the research design. No articles reported adding to or advancing current theoretical underpinnings nor creating new ones. The results of this study show VE research is maturing but is not yet fully mature in the application of theoretical underpinnings in research. Also, this study contributes to analysis of theoretical underpinning usage by demonstrating that theoretical underpinnings are utilized also in course design, not just research design.
Sasakian manifold with pseudo-Riemannian metric

Introduction. Sasakian manifold with Riemannian metric is defined by S. Sasaki [5]. In this paper, we want to define Sasakian manifold with pseudo-Riemannian metric, and discuss the classification of Sasakian manifolds. In section 1, we define a Sasakian manifold (with pseudo-Riemannian metric). In section 2, we define the model spaces of Sasakian manifolds which are used in section 4 for the classification of Sasakian manifolds of constant φ-sectional curvatures. In section 3, we discuss Z)-homothetic deformation which is defined by S. Tanno [9], and prove some fundamental lemmas concerning completeness of the deformed metric. In section 5, we prove that a Sasakian manifold, satisfying R(X, Y) R = 0 for all tangent vectors X and Y, is of constant curvature. In section 6, we discuss a Sasakian manifold M^ which is properly and isometrically immersed in £f.
Experimental Study on the Bending and Shear Behaviors of Chinese Paulownia Wood at Elevated Temperatures

Chinese Paulownia wood has been extensively used in the construction of timber buildings and lightweight sandwich structures. However, the bending and shear behaviors at elevated temperatures were not well understood. A total of 162 specimens were tested to investigate the bending, tangential shear, and radial shear performances of Chinese Paulownia wood under temperatures from 20 to 220 °C. It was found that the bending specimens exhibited ductile failure due to the progressive damage after reaching the peak load, while the tangential and radial shear specimens exhibited brittle shear failure along the shear plane. The elevated temperatures had limited effects on the failure modes. Under the same temperature, the retention rate of the modulus of elasticity is significantly higher than that of the modulus of rupture. Moreover, the bending strength, tangential shear strength, and radial shear strength generally and nonlinearly decreased with the increasing temperature. The EN 1995-1-2 design curve for the shear strength of wood at elevated temperatures is conservative for both the tangential and radial shear specimens. However, the design curve may not be adopted to estimate the tangential shear strength at temperatures higher than 220 °C.

The Effect of Breast Milk Microbiota on the Composition of Infant Gut Microbiota: A Cohort Study

Evidence shows that breast milk microbiota and an infant’s gut microbiota are related. This study aimed to compare the effects of breast milk microbiota on the construction and colonization of gut microbiota in newborns. In this study, 23 healthy infants were selected and divided into a breastfeeding group (13) and a mixed feeding group (10) based on the feeding method within one month of age. Infant fecal and breast milk samples were collected on the day of birth (0 day) and 30 days after birth (30 days) for 16S rRNA second-generation sequencing and SCFA detection. The results showed that Firmicutes and Actinobacteriota on day 0 and Firmicutes and Proteobacteria on 30 d dominated breast milk gut microbiota. There were correlations between the breast milk microbiota and the infant gut microbiota in each group (p < 0.05). Additionally, breast milk microbiota correlated more significantly with infants’ SCFAs in the breastfeeding group than in the mixed feeding group. This study showed that breast milk microbiota partially influences the construction of infant gut microbiota, with some key strains having a crucial influence, such as Lactobacillus, Bifidobacterium, and Enterobacter. However, the effect of breast milk microbiota on infant gut microbiota is not through direct strain transmission but has been indirectly influenced, which may be related to the cross-feeding effect mediated by SCFAs.
