Droplet deposition growth and coalescence

Processes involving the growth, motion and coalescence of fluid droplets have been studied for many years because of their scientific interest and practical importance. Interest in these processes has also been stimulated because they provide simple and often quite beautiful examples of pattern formation phenomena. In recent years it has been shown that a quite wide variety of processes in which droplet coalescence plays a major role exhibit simple asymptotic scaling behavior. These observations have stimulated renewed interest in experimental investigations, computer simulations and theoretical work. In many cases droplet growth and coalescence processes can be described in terms of quite simple models and this makes theoretical work and computer simulations quite attractive. One of the main examples is the condensation of water vapour on a cold surface (breath figures or dropwise condensation). All four stages in the breath figure process (1, droplet growth without coalescence, 2, droplet growth and coalescence without renucleation, 3, growth and coalescence with renucleation and 4, growth, coalescence and renucleation with large droplet removal) can be described in terms of simple computer models and scaling ideas. Recent advances in the study of breath figures and related phenomena is the main focus of this review. Other processes are described in less detail to illustrate the breadth of application of these approaches to phenomena involving droplet coalescence.
RF plasma cleaning of mirror surfaces: characterization, optimization, and surface physics aspects of plasma cleaning

In this study, we present the results from an analysis of the various aspects of the low pressure RF plasma cleaning process for the removal of graphitic carbon contamination layers deposited on different test objects. After determining the optimum parameters for a time-minimized cleaning process using an inductively coupled plasma source as well as oxygen/argon mixtures as feedstock gas, a special emphasis has been put on the characterization of the cleaned surface (Au, Ni, Rh) both in their pristine as well as in their cleaned state. This includes the physical as well as the chemical properties of the surfaces involved. Last but not least, an effort has been made to characterize/monitor the RF plasma during the cleaning procedure in order to allow for an improved process control.
Relationship between e-service quality dimensions and online banking customer satisfaction

Recently, the demand for internet banking has been gradually increasing the number of online banking customers, where the banking clients or customers do not need to visit a bank branch for their transactions. The principal focus of this inquiry is to ascertain how various aspects of e-service quality relate to online baking customers’ happiness, particularly with regard to Bangladeshi commercial banks. Data information was collected from three commercial banks in Bangladesh using an online survey questionnaire, and this study is quantitative and exploratory in nature. The study considered those bank customers who use frequently online/internet banking services. The sample size was n=200, and the study adopted a non-probability sampling approach. Five-point Likert scale was used to measure an item-wise question where “1” stands for “Highly Disagree” and “5” stands for “Highly Agree”. The consequences of this study demonstrate that e-service quality dimensions play a significant role in creating customer satisfaction for online banking customers. The study proposes four hypotheses, and the hypotheses are accepted in this research. Based on this study, bank management should have utilized e-service quality dimensions such as perceived security risk, perceived ease of use, perceived website quality, and perceived responsiveness to create the relationship between e-service quality dimensions and online banking customer satisfaction. Bank management will receive some guidance on developing policies and strategies to improve the satisfaction level of online customers.

The Protective Effect of Walnut Oligopeptides against Indomethacin-Induced Gastric Ulcer in Rats

The aim of this study was to investigate the potential protective effects of walnut oligopeptides (WOPs) on indomethacin-induced gastric ulcers in rats. The rats were divided into the following groups: normal group, model group, omeprazole group (0.02 g/kg), and WOPs groups (0.22, 0.44, and 0.88 g/kg, respectively). After receiving gavage once per day for 30 consecutive days, the rats were injected intraperitoneally with indomethacin 48 mg/kg to induce gastric ulcers. Then, the serum inflammatory cytokines and gastric prostaglandin E2 (PGE2), oxidative stress-related indicators, and the RNA expression of COX-1 and COX-2 were measured. The results revealed that WOPs confer significant gastroprotection on gastric ulcers caused by indomethacin, regulating inflammatory cytokines, oxidative stress, and prostaglandins synthesis, and enhancing the expression of COX-1 and COX-2 in gastric tissue, thus exerting its protective effect on gastric mucosa. The gastroprotective mechanism may be related to the involvement of the arachidonic acid metabolism and upregulation of tryptophan, phenylalanine, tyrosine, and alpha-Linolenic acid metabolism synthesis in vivo.
One-sided confidence bands for cumulative distribution functions

In an earlier article, a method of calculating two-sided confidence bands for cumulative distribution functions was suggested. In this article, the construction of one-sided confidence bands is described. The case of the genera1 location-scale parameter mode1 is discussed, and formulas for the normal and extreme-value models are given as illustrations. A simple numerical example is also included.
The estimation of environmental and genetic trends from records subject to culling.

A very common problem which arises in animal or plant breeding research is that of assessinig the gain which has resulted from a selection program carr'ied oIn ovei a number of years. To be specific, let us suppose that we have a closed dairy herd which has been maintained over a number of years with selection being practiced. The records available for assessing any genetic improvemient consist of production records of cows in the various years and can be represented by a twoway classification, cow by year. At first it might be thought that such a two-way classification could be analyzed by the method of fitting constants [Yates, 1934]. Applications of this technique have, however, led to the apparent conclusion that the environment gradually deteriorated over the period of years, as indicated by the fact that the constants fitted for years tend to decrease year by year. Heinderson [1949] pointed out that a least squares procedure in which the cow effects are regarded as fixed leads to biased estimates. Lush and Shrode [19501 gave a simple explanation of the biases arising in the estimation of age correction factors; similar considerations apply to the estimation of year effects. The present paper is the combined

Validation into Spanish of a Scale to Detect the Post-intensive Care Syndrome

Abstract Objective. This work sought to validate the Spanish version of the scale Healthy Aging Brain-Care Monitor (HABC-M) scale as clinical tool to detect the Post-intensive Care Syndrome. Methods. Psychometric study, conducted in adult intensive care units from two high-complexity university hospitals in Colombia. The sample was integrated by 135 survivors of critical diseases with mean age of 55 years. The translation of the HABC-M was carried out through transcultural adaptation, evaluating content, face, and construct validity and determining the scale’s reliability. Results. A replica was obtained of the HABC-M scale in its version into Spanish, semantically and conceptually equivalent to the original version. The construct was determined through confirmatory factor analysis (CFA), evidencing a three-factor model comprised of the subscales: cognitive (6 items), functional (11 items), and psychological (10 items), with a confirmatory factor index (CFI) of 0.99, a Tucker Lewis index (TLI) of 0.98, and an approximate root-mean-square error (RMSE) of 0.073 (90% CI: 0.063 - 0.084). Internal consistency was determined through Cronbach’s alpha coefficient, obtaining 0.94, (95% CI 0.93 - 0.96). Conclusion. The Spanish of the HABC-M scale is a tool with adequate psychometric properties, validated and reliable to detect the Post-intensive Care Syndrome.
The dynamics of contractions

We show that, providing a metric space $X$ has a boundary that is in some sense similar to the boundary of hyperbolic space, the iterates of a contraction $f:X\to X$ converge locally uniformly to a point in, or on the boundary of, $X$. This generalises the Denjoy–Wolff theorem for analytic self-maps of the unit disc in the complex plane, and also shows that if $D$ is a bounded strictly convex subdomain of ${\Bbb R}^n$, then any contraction of $D$ with respect to the Hilbert metric of $D$ converges to a point in the closure of $D$.
X-ray and optical observations of the Shapley supercluster in Hydra–Centaurus

X-ray and optical observations of the Shapley Supercluster, at redshifts between 0.037 and 0.053 in the region of Hydra and Centaurus, are presented. Six of the 46 X-ray brightest clusters at high galactic latitude belong to this supercluster. The Local Supercluster is less luminous in X-rays than the least-luminous cluster found here, and only the Centaurus cluster in the Hydra-Centaurus Supercluster is more luminous than the weakest cluster detected in the Shapley Supercluster. The optical and X-ray luminosity functions suggest that there are large deviations from the Hubble flow in the region and that clusters are merging at a high rate.
The queue GI/M/s with customers of different types or the queue GI/Hm/s

We study the queue GI/M/s with customers of m different types. An arriving customer is of type i with probability pi and the types of different customers are independent. A customer of type i requires a service time which is exponentially distributed with parameter bi. This model is equivalent to the queue GIIHm/s, where Hm denotes a mixture of m different exponential distributions. We are primarily interested in the distributions of waiting times and queue lengths. Using a probabilistic argument we reduce the problem to the solution of a system of Wiener-Hopf-type equations. This system is solved by a factorization method. Thus we obtain explicit results for the stationary distributions of waiting times and queue lengths.
Modeling of two-dimensional nanoscale Y-bent plasmonic waveguides with cavities for demultiplexing of the telecommunication wavelengths

Numerical simulations, based on a finite-difference-time-domain (FDTD) method, of infrared light propagation for add/drop filtering in two-dimensional (2D) metal–insulator–metal (Ag–SiO2–Ag) resonators are reported to design 2D Y-bent plasmonic waveguides with possible applications in telecommunication wavelength demultiplexing (WDM). First, we study optical transmission and reflection of a nanoscale SiO2 waveguide coupled to a nanocavity of the same insulator located either inside or on the side of a linear waveguide sandwiched between Ag. According to the inside or outside positioning of the nanocavity with respect to the waveguide, the transmission spectrum displays peaks or dips, respectively, which occur at the same central frequency. A fundamental study of the possible cavity modes in the near-infrared frequency band is also given. These filtering properties are then exploited to propose a nanoscale demultiplexer based on a Y-shaped plasmonic waveguide for separation of two different wavelengths, in selection or rejection, from an input broadband signal around 1550 nm. We detail coupling of the 2D add/drop Y connector to two cavities inserted on each of its branches. Selection or rejection of a pair of different wavelengths depends on the inside or outside locations (respectively) of each cavity in the Y plasmonic device.
Non-Invasive Sex Determination of Nestlings and Adult Bonelli’s Eagles Using Morphometrics

Simple Summary This study explores the use of biometric analysis to identify the sex of Bonelli’s eagles, a bird species with reverse sexual dimorphism where females are usually larger than males. By using linear discriminant analysis of biometric variables, we were able to obtain equations that accurately distinguished between male and female eagles, using just two measurements. The study included 137 Bonelli’s eagles, 82 nestlings and 55 adults, sampled in eastern Spain from 2015 to 2022. The validation procedure reduced the number of variables used, increasing the accuracy of sexing and saving time. Results showed that the lateral tarsus length and dorso-ventral tarsus length measurements were the most effective in distinguishing between male and female eagles of all age classes, while other variables showed some overlap between sexes. This non-invasive method has multiple applications, including estimation of sex ratio for further studies on population dynamics and extinction risk assessments, which could contribute to the conservation of this endangered species. Abstract Biometric analysis allows the sexing of most vertebrates, particularly birds. Birds of prey, and, especially, the Bonelli’s eagle (Aquila fasciata), show reverse sexual dimorphism (i.e., females are usually larger than males). In contrast to blood sampling, the use of morphometrics allows sex determination using a non-invasive method, and, therefore, it facilitates fieldwork. By means of a linear discriminant analysis of biometric variables, we obtained different equations that allow the sexing of nestlings and adult Bonelli’s eagles. We sampled 137 Bonelli’s eagles, 82 nestlings and 55 adults in eastern Spain during the period 2015–2022. The sexes obtained after linear discriminant analysis were compared with their molecular sexing. The validation procedure of the linear discriminant equations facilitated the reduction of the number of variables used and, consequently, optimised working time and sexing accuracy. After validation, some equations showed a 100% sexing efficiency for Bonelli’s eagles, particularly for adults. Our results showed that the variables with smaller overlap between the sexes were the lateral tarsus length and dorso-ventral tarsus length, particularly in nestlings. The rest of the variables showed some overlap between the sexes in both age classes. The results we obtained enable the sexing of juvenile and adult Bonelli’s eagles in the field using just these two measurements. Hence, this is an easy, accurate, quick and non-invasive method with multiple applications, including in studies on population dynamics, survival analysis or extinction risk assessments, which, ultimately, could contribute to the improvement of the conservation status of this endangered species.
Interaction of Terminal Oxidases with Amphipathic Molecules

The review focuses on recent advances regarding the effects of natural and artificial amphipathic compounds on terminal oxidases. Terminal oxidases are fascinating biomolecular devices which couple the oxidation of respiratory substrates with generation of a proton motive force used by the cell for ATP production and other needs. The role of endogenous lipids in the enzyme structure and function is highlighted. The main regularities of the interaction between the most popular detergents and terminal oxidases of various types are described. A hypothesis about the physiological regulation of mitochondrial-type enzymes by lipid-soluble ligands is considered.
Assessing the Impact of Business Model Innovation on Firm Performance: Insights from the China Growth Enterprise Market

This article explores the impact of business model innovation (BMI) on firm performance by analyzing 2,970 annual reports of firms in the China Growth Enterprise Market (GEM) from 2012 to 2017. The dependent variable bmi is constructed using crawler technology to reflect the business model innovation of the research sample. Four financial indicators, i.e. gross profit ratio total assets (GPA), earnings per share (EPS), return on total assets (ROA), and return on equity (ROE), are used to represent firm performance. The results suggest that BMI has a positive impact on a firm's performance in China, and the robustness test confirms the findings. This study provides empirical evidence of the impacts of BMI on firm performance in the China GEM and offers managerial implications for governments, firms, and entrepreneurs.
Revealing galactic scale bars with the help of Galaxy Zoo

Abstract We use visual classifications of the brightest 250,000 galaxies in the Sloan Digital Sky Survey Main Galaxy Sample provided by citizen scientists via the Galaxy Zoo project (www.galaxyzoo.org, Lintott et al. 2008) to identify a sample of local disc galaxies with reliable bar identifications. These data, combined with information on the atomic gas content from the ALFALFA survey (Haynes et al. 2011) show that disc galaxies with higher gas content have lower bar fractions. We use a gas deficiency parameter to show that disc galaxies with more/less gas than expected for their stellar mass are less/more likely to host bars. Furthermore, we see that at a fixed gas content there is no residual correlation between bar fraction and stellar mass. We argue that this suggests previously observed correlations between galaxy colour/stellar mass and (strong) bar fraction (e.g. from the sample in Masters et al. 2011, and also see Nair & Abraham 2010) could be driven by the interaction between bars and the gas content of the disc, since more massive, optically redder disc galaxies are observed to have lower gas contents. Furthermore we see evidence that at a fixed gas content the global colours of barred galaxies are redder than those of unbarred galaxies. We suggest that this could be due to the exchange of angular momentum beyond co-rotation which might stop a replenishment of gas from external sources, and act as a source of feedback to temporarily halt or reduce the star formation in the outer parts of barred discs. These results (published as Masters et al. 2012) combined with those of Skibba et al. (2012), who use the same sample to show a clear (but subtle and complicated) environmental dependence of the bar fraction in disc galaxies, suggest that bars are intimately linked to the evolution of disc galaxies.
A robust model reference adaptive control without strictly positive real condition

This paper considers the model reference adaptive control problem for the system (1) with unmodelled dynamics m n dominated by a small constant k multiplied by a quantity dependent on the input, output and noise. Using bounded external excitation and randomly varying truncation techniques, we give design method of a model reference adaptive controller which is similar to that in Meyn and Brown (1992). It is shown that the closed-loop system is globally stable, the estimation error for parameter contained in the modelled part is of order k, and the closed-loop system under the model reference adaptive control law is suboptimal in the sense of lim sup 1/n n (A m (z) y i+1 - B m (z)z* i - C m (z) w i+1 ) 2 h O( k 2 ) + n 2 b 1 2 while the SPR condition usually used in other papers is replaced by a stability condition.
Interferometric autocorrelation of an attosecond pulse train calculated using feasible formulae

The autocorrelation trace of an attosecond pulse train (APT) directly revealed the pulse envelope in our recent experiment on measuring the two-photon Coulomb explosion of a nitrogen molecule as a correlation signal. Although the spatial overlap of the two replicas of the APT in the correlation measurement was only achieved near the focal region owing to the spatial split of the measured APT field, which is a situation quite different from that of the correlation measurement using a Michelson interferometer, the interference fringes clearly appeared on the correlation envelope and provedthe odd symmetry of the electric field to the time translation with a half-period of the driving laser field. In this paper, we show a simple and practical analysis for the propagation and the nonlinear interaction of an APT to simulate the experimental result of the interferometric autocorrelation of the spatially split APT. The spatial convolution of the focused electric field is essential for obtaining the fringes. We also discuss how the autocorrelation should be described in the context of the second-order perturbation theory within a dipole approximation.
Population recovery and occurrence of the endemic Rhine sculpin (Cottus rhenanus)

The Rhine sculpin (Cottus rhenanus) is a benthic rheophilic fish species that is endemic to tributaries of the rivers Rhine and Meuse in North-western Europe. Little is known about its occurrence and individuals density in relation to habitat characteristics. A core population of C. rhenanus occurs in the River Geul in the Netherlands. Since the late 19th century, this river was heavily polluted by communal and industrial wastewater, causing a strong population decline. As the core population of C. rhenanus is recovering, the status, distribution, and habitat use could be studied to facilitate recovery in other locations. Cottus rhenanus density of individuals significantly increased over the period 2005–2015 and it became one of the most abundant fish species in assemblages. Negative relationships were observed between C. rhenanus densities and a high abundance of boulders (>200 mm), large structures such as woody debris, and water depth. The population increase and recolonization of C. rhenanus coincided with water quality improvement, which suggests that this fish species can be used to assess small streams ecosystem integrity. The recent range expansion of the Ponto-Caspian round goby (Neogobius melanostomus) poses a high risk of negative effects on C. rhenanus populations via food and shelter competition. Further water quality improvement, habitat conservation, and prevention of the spread of invasive gobies could favour C. rhenanus populations within their natural range.
