THE SPATIALLY RESOLVED NUV–r COLOR OF LOCAL STAR-FORMING GALAXIES AND CLUES FOR QUENCHING

Using a sample of ∼6000 local face-on star-forming galaxies (SFGs) we examine the correlations between the NUV–r colors both inside and outside the half-light radius, stellar mass M*, and Sérsic index n to understand how the quenching of star formation is linked to galaxy structure. For these less dust-attenuated galaxies, NUV–r is found to be linearly correlated with D n 4000 ? > , supporting NUV–r as a good photometric indicator of stellar age (or specific star formation rate). First, we find that at M * < 10 10.2 M ⊙ ? > the central NUV–r is on average only ∼0.25 mag redder than the outer NUV–r; the intrinsic value would be even smaller after accounting for dust correction. However, the central NUV–r becomes systematically much redder than the outer NUV–r for more massive galaxies at M * > 10 10.2 M ⊙ ? > . Second, the central NUV–r shows no dependence on Sérsic index n at M * < 10 10.2 M ⊙ ? > , while above this mass galaxies with a higher n tend to be redder in the central NUV–r color. These results suggest that galaxies with M * < 10 10.2 M ⊙ ? > exhibit similar star formation activity from the inner R < R 50 ? > region to the R > R 50 ? > region. In contrast, a considerable fraction of the M * > 10 10.2 M ⊙ ? > galaxies, especially those with a high n, have harbored a relatively inactive bulge component.
An integrative review exploring the impact of Electronic Health Records (EHR) on the quality of nurse–patient interactions and communication

Abstract Aim To explore how nurses' use of electronic health records impacts on the quality of nurse–patient interactions and communication. Design An integrative review. Data sources MEDLINE®, CINAHL®, PscyINFO, PubMed, BNI and Cochrane Library databases were searched for papers published between January 2005 and April 2022. Review methods Following a comprehensive search, the studies were appraised using a tool appropriate to the study design. Data were extracted from the studies that met the inclusion criteria relating to sample characteristics, methods and the strength of evidence. Included empirical studies had to examine interactions or communication between a nurse and patient while electronic health records were being used in any healthcare setting. Findings were synthesized using a thematic approach. Results One thousand nine hundred and twenty articles were initially identified but only eight met the inclusion criteria of this review. Thematic analysis revealed four key themes, indicating that EHR: impedes on face‐to‐face communication, promotes task‐orientated and formulaic communication and impacts on types of communication patterns. Conclusion Research examining nurse–patient interactions and communication when nurses' use electronic health records is limited but evidence suggests that closed nurse–patient communications, reflecting a task‐driven approach, were predominantly used when nurses used electronic health records, although some nurses were able to overcome logistical barriers and communicate more openly. Nurses' use of electronic health records impacts on the flow, nature and quality of communication between a nurse and patient. Impact The move to electronic health records has taken place largely without consideration of the impact that this might have on nurse–patient interaction and communication. There is evidence of impact but also evidence of how this might be mitigated. Nurses must focus future research on examining the impact that these systems have, and to develop strategies and practice that continue to promote the importance of nurse–patient interactions and communication. Patient or Public contribution Studies examined within this review included patient participants that informed the analysis and interpretation of data.
The existence and concentration of positive ground state solutions for a class of fractional Schrödinger-Poisson systems with steep potential wells

The present study is concerned with the following fractional Schrodinger-Poisson system with steep potential well: $$ \left\{% \begin{array}{ll} (-\Delta)^s u+ \la V(x)u+K(x)\phi u= f(u), & x\in\R^3, (-\Delta)^t \phi=K(x)u^2, & x\in\R^3, \end{array}% \right. $$ where $s,t\in(0,1)$ with $4s+2t>3$, and $\la>0$ is a parameter. Under certain assumptions on $V(x)$, $K(x)$ and $f(u)$ behaving like $|u|^{q-2}u$ with $2<q<2_s^*=\frac{6}{3-2s}$, the existence of positive ground state solutions and concentration results are obtained via some new analytical skills and Nehair-Pohožaev identity. In particular, the monotonicity assumption on the nonlinearity is not necessary.
THE MERGER-DRIVEN EVOLUTION OF MASSIVE GALAXIES

We explore the rate and impact of galaxy mergers on the massive galaxy population using the amplitude of the two-point correlation function on small scales for M* > 5 × 1010 M☉ galaxies from the COSMOS and COMBO-17 surveys. Using a pair fraction derived from the Sloan Digital Sky Survey as a low-redshift benchmark, the large survey area at intermediate redshifts allows us to determine the evolution of the close-pair fraction with unprecedented accuracy for a mass-selected sample: we find that the fraction of galaxies more massive than 5 × 1010 M☉ in pairs separated by less than 30 kpc in three-dimensional space evolves as F(z) = (0.0130 ± 0.0019) × (1 + z)1.21± 0.25 between z = 0 and z = 1.2. Assuming a merger timescale of 0.5 Gyr, the inferred merger rate is such that galaxies with mass in excess of 1011 M☉ have undergone, on average, 0.5 (0.7) mergers involving progenitor galaxies both more massive than 5 × 1010 M☉ since z = 0.6 (1.2). We also study the number density evolution of massive red sequence galaxies using published luminosity functions and constraints on the M/LB evolution from the fundamental plane. Moreover, we demonstrate that the measured merger rate of massive galaxies is sufficient to explain this observed number density evolution in massive red sequence galaxies since z = 1.
BARS DO DRIVE SPIRAL DENSITY WAVES

Recently, Buta et al. examined the question “Do Bars Drive Spiral Density Waves? ”, an idea supported by theoretical studies and also from a preliminary observational analysis. They estimated maximum bar strengths Qb, maximum spiral strengths Qs, and maximum m = 2 arm contrasts A2s for 23 galaxies with deep Anglo-Australian Telescope (AAT) Ks-band images. These were combined with previously published Qb and Qs values for 147 galaxies from the Ohio State University Bright Spiral Galaxy Survey (OSUBSGS) sample and with the 12 galaxies from Block et al. Weak correlation between Qb and Qs was confirmed for the combined sample, whereas the AAT subset alone showed no significant correlations between Qb and Qs, nor between Qb and A2s. A similar negative result was obtained in Durbala et al. for 46 galaxies. Based on these studies, the answer to the above question remains uncertain. Here we use a novel approach, and show that although the correlation between the maximum bar and spiral parameters is weak, these parameters do correlate when compared locally. For the OSUBSGS sample, a statistically significant correlation is found between the local spiral amplitude, and the forcing due to the bar's potential at the same distance, out to ≈1.6 bar radii (the typical bar perturbation is then of the order of a few percent). Also for the sample of 23 AAT galaxies of Buta et al., we find a significant correlation between local parameters out to ≈1.4 bar radii. Our new results confirm that, at least in a statistical sense, bars do indeed drive spiral density waves.
Nickel nanoparticles induce epithelial-mesenchymal transition in human bronchial epithelial cells via the HIF-1α/HDAC3 pathway

Abstract We and others have previously demonstrated that exposure to nickel nanoparticles (Nano-Ni) caused fibrogenic and carcinogenic effects; however, the underlying mechanisms are still not fully understood. This study aimed to investigate the effects of Nano-Ni on epithelial-mesenchymal transition (EMT) in human bronchial epithelial cells (BEAS-2B) and its underlying mechanisms since EMT is involved in both cancer pathogenesis and tissue fibrosis. Our results showed that exposure to Nano-Ni, compared to the control Nano-TiO2, caused a remarkable decrease in the expression of E-cadherin and an increase in the expression of vimentin and α-SMA, indicating an inducible role of Nano-Ni in EMT development in human bronchial epithelial cells. HIF-1α nuclear accumulation, HDAC3 upregulation, and decreased histone acetylation were also observed in the cells exposed to Nano-Ni, but not in those exposed to Nano-TiO2. Pretreatment of the cells with a specific HIF-1α inhibitor, CAY10585, or HIF-1α-specific siRNA transfection prior to Nano-Ni exposure resulted in the restoration of E-cadherin and abolished Nano-Ni-induced upregulation of vimentin and α-SMA, suggesting a crucial role of HIF-1α in Nano-Ni-induced EMT development. CAY10585 pretreatment also attenuated the HDAC3 upregulation and increased histone acetylation. Inhibition of HDAC3 with specific siRNA significantly restrained Nano-Ni-induced reduction in histone acetylation and restored EMT-related protein expression to near control levels. In summary, our findings suggest that exposure to Nano-Ni promotes the development of EMT in human bronchial epithelial cells by decreasing histone acetylation through HIF-1α-mediated HDAC3 upregulation. Our findings may provide information for further understanding of the molecular mechanisms of Nano-Ni-induced fibrosis and carcinogenesis.
Systematic Assessment of Prosthesis Stiffness on User Biomechanics Using the Lower Leg Trajectory Error Framework and its Implication for the Design and Evaluation of Ankle-Foot Prostheses.

Advances in understanding the effects the mechanical characteristics of prosthetic feet on user biomechanics have enabled passive prostheses to improve the walking pattern of people with lower limb amputation. However, there is no consensus on the design methodology and criteria required to maximize specific user outcomes and fully restore their mobility. The Lower Leg Trajectory Error (LLTE) framework is a novel design methodology based on the replication of lower leg dynamics. The LLTE value evaluates how closely a prosthetic foot replicates a target walking pattern. Designing a prosthesis that minimizes the LLTE value, optimizes its mechanical function to enable users to best replicate the target lower leg trajectory. Here, we conducted a systematic sensitivity investigation of LLTE-optimized prostheses. Five people with unilateral transtibial amputation walked overground at self-selected speeds using five prototype energy storage and return feet with varying LLTE values. The prototypes LLTE values were varied by changing the stiffness of the participant's LLTE-optimized design by 60%, 80%, 120% and 167%. Users most closely replicated the target able-bodied walking pattern with the LLTE-optimized stiffness, experimentally demonstrating that the predicted optimum was a true optimum. Additionally, the predicted LLTE values were correlated to the user's ability to replicate the target walking pattern, user preferences, and clinical outcomes including roll-over geometries, trunk sway, prosthetic energy return, and peak push-off power. This study further validates the use of the LLTE framework as a predictive and quantitative tool for designing and evaluating prosthetic feet.
Difference Nevanlinna theories with vanishing and infinite periods

By extending the idea of a difference operator with a fixed step to varying-steps difference operators, we have established a difference Nevanlinna theory for meromorphic functions with the steps tending to zero (vanishing period) and a difference Nevanlinna theory for finite order meromorphic functions with the steps tending to infinity (infinite period) in this paper. We can recover the classical little Picard theorem from the vanishing period theory, but we require additional finite order growth restriction for meromorphic functions from the infinite period theory. Then we give some applications of our theories to exhibit connections between discrete equations and and their continuous analogues.
Statistical properties of eigenvectors and eigenvalues of structured random matrices

We study the eigenvalues and the eigenvectors of N×N structured random matrices of the form H=WH~W+D with diagonal matrices D and W and H~ from the Gaussian Unitary Ensemble. Using the supersymmetry technique we derive general asymptotic expressions for the density of states and the moments of the eigenvectors. We find that the eigenvectors remain ergodic under very general assumptions, but a degree of their ergodicity depends strongly on a particular choice of W and D. For a special case of D = 0 and random W, we show that the eigenvectors can become critical and are characterized by non-trivial fractal dimensions.
Prevention of Dental Biofilm Formation with Polyphenols: A Systematic Review

Abstract Polyphenols are plant secondary products with health-promoting properties against various degenerative or infectious diseases, and thus may help in the prevention of oral diseases. The aim of the present systematic review was to investigate polyphenols as a possible adjuvant in inhibiting dental biofilm formation, which is an important precondition for the most prevalent oral disease – caries and periodontitis. A literature search was conducted using the databases PubMed, CENTRAL and Scopus. Only studies with oral healthy participants and plaque level as outcome were included. Data search and extraction was conducted by two authors independently. Of the 211 initially identified studies, only six met all inclusion criteria. Meta-analysis was performed with five studies using the random effect model. Treatment with polyphenols reduced the plaque level in comparison to a negative control, but not significantly. Strong evidence of heterogeneity was observed. The diversity and complexity of polyphenols and their preparation need to be considered. There is no clear evidence that clinical use of polyphenols can prevent dental biofilm formation. Additional research with more and larger randomized controlled trials are required.
Evaluation of physical activity calorie equivalent (PACE) labels’ impact on energy purchased in cafeterias: A stepped-wedge randomised controlled trial

Background A recent meta-analysis suggested that using physical activity calorie equivalent (PACE) labels results in people selecting and consuming less energy. However, the meta-analysis included only 1 study in a naturalistic setting, conducted in 4 convenience stores. We therefore aimed to estimate the effect of PACE labels on energy purchased in worksite cafeterias in the context of a randomised study design. Methods and findings A stepped-wedge randomised controlled trial (RCT) was conducted to investigate the effect of PACE labels (which include kcal content and minutes of walking required to expend the energy content of the labelled food) on energy purchased. The setting was 10 worksite cafeterias in England, which were randomised to the order in which they introduced PACE labels on selected food and drinks following a baseline period. There were approximately 19,000 workers employed at the sites, 72% male, with an average age of 40. The study ran for 12 weeks (06 April 2021 to 28 June 2021) with over 250,000 transactions recorded on electronic tills. The primary outcome was total energy (kcal) purchased from intervention items per day. The secondary outcomes were: energy purchased from non-intervention items per day, total energy purchased per day, and revenue. Regression models showed no evidence of an overall effect on energy purchased from intervention items, −1,934 kcals per site per day (95% CI −5,131 to 1,262), p = 0.236, during the intervention relative to baseline, equivalent to −5 kcals per transaction (95% CI −14 to 4). There was also no evidence for an effect on energy purchased from non-intervention items, −5 kcals per site per day (95% CI −513 to 504), p = 0.986, equivalent to 0 kcals per transaction (95% CI −1 to 1), and no clear evidence for total energy purchased −2,899 kcals per site (95% CI −5,810 to 11), p = 0.051, equivalent to −8 kcals per transaction (95% CI −16 to 0). Study limitations include using energy purchased and not energy consumed as the primary outcome and access only to transaction-level sales, rather than individual-level data. Conclusion Overall, the evidence was consistent with PACE labels not changing energy purchased in worksite cafeterias. There was considerable variation in effects between cafeterias, suggesting important unmeasured moderators. Trial registration The study was prospectively registered on ISRCTN (date: 30.03.21; ISRCTN31315776).
Satellite mapping of urban built-up heights reveals extreme infrastructure gaps and inequalities in the Global South

Significance Information on urban built-up heights globally is needed to evaluate the effects of urban form and infrastructure on the environment, the economy, and human well-being. This study provides a global atlas of urban built-up heights and shows large spatial variations in built-up heights at continental, country, and city levels. The results reveal extreme gaps in urban built-up infrastructure availability in the Global South and large inequality in built-up infrastructure in most countries, but largest in the Global South compared with the Global North. The atlas has the potential to improve our understanding of the effects of urbanization on raw material demand, embodied and operational energy use, and urban development intensity.
Sooner, later, or never: Changing fertility intentions due to Covid-19 in China’s Covid-19 epicentre

Using survey data collected from Hubei province, China’s Covid-19 epicentre, in August 2020, this study examines how fertility intentions of Chinese citizens changed during the Covid-19 pandemic. We consider not only whether people changed their fertility plans due to Covid-19 but also distinguish three types of change: bringing forward (‘sooner’), postponing (‘later’), and abandoning (‘never’) planned fertility. Over half of those who planned to have a child intended to change their fertility plans due to Covid-19. Younger individuals, those of non-Han ethnicities, urban residents, those with one child already, and those with ever-infected family members were more likely to change their fertility plans. While the effects of some characteristics seem to be short term, other characteristics such as age and number of children show more consequential influences. Older individuals and those planning their second child were particularly prone to abandoning their childbearing plans due to Covid-19. The pandemic may thus complicate China’s latest efforts to boost its low fertility.
Complex geodesics in convex domains and $\mathbb C$-convexity of semitube domains

In the paper the complex geodesics of a convex domain in $\mathbb C^n$ are studied. One of the main results of the paper provides certain necessary condition for a holomorphic map to be a complex geodesic for a convex domain in $\mathbb C^n$. The established condition is of geometric nature and it allows to find a formula for every complex geodesic. The $\mathbb C$-convexity of semitube domains is also discussed.
Antibody status following booster vaccination against SARS‐CoV‐2 virus in patients with haematologic malignancies

Antibody titres in 462 patients with haematological malignancies after the second (D2) and third (D3) SARS‐CoV‐2 vaccine were compared with those of healthy controls (HCs). Significant decay of antibody titre was observed pre D3, but titre surged post D3. The number of seronegative patients decreased from 79 (17.1%) to 44 (9.5%) from post D2 to post D3, and patients with adequate antibody titre increased from 204 (44.2%) to 358 (77.5%). Of the patients who received B‐cell‐targeted therapy, 80% were seronegative and 71% remained seronegative after D3. CD19+, CD4+, CD8+ cell counts, and immunoglobulin G (IgG) levels were identified as independent predictors for adequate serologic response.
The effectiveness of activity pacing interventions for people with chronic fatigue syndrome: a systematic review and meta-analysis

Abstract Purpose To investigate whether activity pacing interventions (alone or in conjunction with other evidence-based interventions) improve fatigue, physical function, psychological distress, depression, and anxiety in people with chronic fatigue syndrome (CFS). Materials and methods Seven databases were searched until 13 August 2022 for randomised controlled trials that included activity pacing interventions for CFS and a validated measure of fatigue. Secondary outcomes were physical function, psychological distress, depression, and anxiety. Two reviewers independently screened studies by title, abstract and full text. Methodological quality was evaluated using the PEDro scale. Random-effects meta-analyses were performed in R. Results 6390 articles were screened, with 14 included. Good overall study quality was supported by PEDro scale ratings. Activity pacing interventions were effective (Hedges’ g (95% CI)) at reducing fatigue (–0.52 (–0.73 to −0.32)), psychological distress (–0.37 (–0.51 to −0.24)) and depression (–0.29 (–0.49 to −0.09)) and improving physical function (mean difference 7.18 (3.17–11.18)) when compared to no treatment/usual care. The extent of improvement was greater for interventions that encouraged graded escalation of physical activities and cognitive activities. Conclusion Activity pacing interventions are effective in reducing fatigue and psychological distress and improving physical function in CFS, particularly when people are encouraged to gradually increase activities. Registration PROSPERO CRD42016036087. IMPLICATIONS FOR REHABILITATION A key feature of chronic fatigue syndrome (CFS) is a prolonged post-exertional exacerbation of symptoms following physical activities or cognitive activities. Activity pacing is a common strategy often embedded in multi-component management programs for CFS. Activity pacing interventions are effective in reducing fatigue and psychological distress and improving physical function in CFS, particularly when patients are encouraged to gradually increase their activities. Healthcare professionals embedding activity pacing as part of treatment should work collaboratively with patients to ensure successful, individualised self-management strategies.
Lattice Path Matroids: Negative Correlation and Fast Mixing

Catalan numbers arise in many enumerative contexts as the counting sequence of combinatorial structures. In this work, we consider natural Markov chains on some of the realizations of the Catalan sequence. While our main result is in deriving an O(n 2 log n) bound on the mixing time in L2 (and hence total variation) distance for the random transposition chain on Dyck paths, we raise several open questions, including the optimality of the above bound. The novelty in our proof is in establishing a certain negative correlation property among random bases of lattice path matroids, including the so-called Catalan matroid which can be defined using Dyck paths.
