Can dogs help chickens? Pet owners’ willingness to pay for animal welfare-friendly pet food in the United States

Consumer concern about farmed animal welfare is growing but does not always translate into real-world purchasing behaviour of welfare-friendly animal products for human consumption. Possible reasons for this include unfamiliarity with farming practices and economic sensitivity. In contrast, the number and role of pets in the United States have grown measurably, and spending on pets is strong. The pet food market has many opportunity niches as pet owners navigate strong marketing trends and nutrition philosophies. We hypothesised that pet owners in the US would be willing to pay a premium for pet food containing welfare-friendly animal ingredients. Eight hundred and thirty-eight pet owners completed an online survey asking questions that measured their knowledge of and interest in farm animal welfare, and their willingness-to-pay for pet food labelled as farm animal welfare-friendly. Respondents overall displayed relatively low knowledge about farm animal welfare, but poor self-assessment of their own knowledge. They displayed interest in farm animal welfare and an overall positive mean willingness-to-pay (WTP) for welfare-friendly pet food. Younger respondents, women and cat owners displayed a higher WTP than older respondents, men and dog owners. Income level was not correlated to WTP. Creating pet food products that contain animal ingredients produced using welfare-friendly practices may enhance farm animal welfare via two primary avenues: by providing a sustainable and value-added outlet for the by-products of welfare-friendly human food products, and by providing an educational opportunity about farm animal production via pet food packaging and other advertising.
Forward-backward method for scattering from dielectric rough surfaces

The iterative forward-backward (FB) method is a recently proposed efficient technique for numerical evaluation of scattering from perfectly conducting rough surfaces. Extension of the method to include scattering from imperfect conducting surfaces, with a high imaginary part of the complex dielectric constant, has also been proposed. The FB method is further generalized to analyze scattering from dielectric rough surfaces with arbitrary complex dielectric constant. Electric and magnetic equivalent surface currents are split into forward and backward components and equations governing these current components are obtained. As a solution, an iterative scheme is proposed and its convergence rate is analyzed. Finally, the effectiveness of the method is assessed by comparing the obtained scattering results with "exact" ones, computed by employing the usual method of moments (MoM).
Accurate Numerical Prediction of Incompressible Fluid Flow in Lid-Driven Cavities

In this paper, we report an efficient numerical method to predict fluid flow behavior in a square and deep lid-driven cavities. The conventional continuity and momentum equations are transformed into stream-function and vorticity formulation to reduce the number of unknown spatial quantities. Numerical experiments were performed with different values of aspect ratio and Reynolds number to investigate the effect of these dimensionless parameters on the fluid flow behavior in the cavity. In the current study, we found that the dynamics and the structure of primary vortex are significantly affected by the Reynolds number and the aspect ratio of the cavity.
Genetic Characterization and Pathogenesis of Avian Influenza Virus H3N8 Isolated from Chinese pond heron in China in 2021

In October 2021, a wild bird-origin H3N8 influenza virus-A/Chinese pond heron/Jiangxi 5-1/2021 (H3N8)-was isolated from Chinese pond heron in China. Phylogenetic and molecular analyses were performed to characterize the genetic origin of the H3N8 strain. Phylogenetic analysis revealed that eight gene segments of this avian influenza virus H3N8 belong to Eurasian lineages. HA gene clustered with avian influenza viruses is circulating in poultry in southern China. The NA gene possibly originated from wild ducks in South Korea and has the highest homology (99.3%) with A/Wild duck/South Korea/KNU2020-104/2020 (H3N8), while other internal genes have a complex and wide range of origins. The HA cleavage site is PEKQTR↓GLF with one basic amino acid, Q226 and T228 at HA preferentially bind to the alpha-2,3-linked sialic acid receptor, non-deletion of the stalk region in the NA gene and no mutations at E627K and D701N of the PB2 protein, indicating that isolate A/Chinese pond heron/Jiangxi 5-1/2021 (H3N8) was a typical avian influenza with low pathogenicity. However, there are some mutations that may increase pathogenicity and transmission in mammals, such as N30D, T215A of M1 protein, and P42S of NS1 protein. In animal studies, A/Chinese pond heron/Jiangxi 5-1/2021 (H3N8) replicates inefficiently in the mouse lung and does not adapt well to the mammalian host. Overall, A/Chinese pond heron/Jiangxi 5-1/2021 (H3N8) is a novel wild bird-origin H3N8 influenza virus reassortant from influenza viruses of poultry and wild birds. This wild bird-origin avian influenza virus is associated with wild birds along the East Asian-Australasian flyway. Therefore, surveillance of avian influenza viruses in wild birds should be strengthened to assess their mutation and pandemic risk in advance.
Design of a 1-bit 256-element Reconfigurable Transmitarray at Ka-band

This paper presents the design and simulation procedure of a 1-bit 256-element linearly-polarized (LP) reconfigurable transmitarray antenna (RTA) in Ka-band. The RTA unit-cell (UC) size is $0.48 \lambda \times 0.48\lambda \times 0.11 \lambda$, where a pair of p-in diodes are integrated to realize an 180° phase shift and thus a 1-bit discrete phase quantization is made. 3-D beam scanning is then realized by certain discrete phase distribution calculated by ray tracing method (RTM). According to full wave simulation results, the peak gain is 21.3dBi/21.5dBi in E/H-plane at 28GHz, respectively. Moreover, it has good beam scanning performance with scanning range of 45° in both E-plane and H-plane.
Observations of Temperature in the Upper Troposphere and Lower Stratosphere of Tropical Weather Disturbances

AbstractMicrowave temperature profiler (MTP) data are analyzed to document temperature signatures in the upper troposphere and lower stratosphere that accompany Atlantic tropical weather disturbances. The MTP was deployed on the National Science Foundation–National Center for Atmospheric Research Gulfstream V (GV) aircraft during the Pre-Depression Investigation of Cloud-Systems in the Tropics (PREDICT) in August and September 2010.Temporal variations in cold-point temperature compared with infrared cloud-top temperature reveal that organized deep convection penetrated to near or beyond the cold point for each of the four disturbances that developed into a tropical cyclone. Relative to the lower-tropospheric circulation center, MTP and dropsonde data confirmed a stronger negative radial gradient of temperature in the upper troposphere (10–13 km) of developing disturbances prior to genesis compared with nondeveloping disturbances. The MTP data revealed a somewhat higher and shallower area of relative warmt.
Quantum flux operators and thermal rate constant: Collinear H+H2

The exact quantum formulation of the thermal rate constant, k(T), given by Miller et al. [W. H. Miller, J. Chem. Phys. 61, 1823 (1974); W. H. Miller, S. D. Schwartz, and J. W. Tromp, ibid. 79, 4889 (1983)] is evaluated in a localized L2 basis (distributed Gaussian basis) for two model problems. In considering the accuracy, feasibility, and computational efficiency of this approach, we demonstrate novel properties of the flux operator, namely the paucity of nonzero eigenvalues. This contributes greatly to the efficiency of the L2 approach. Finally, we show that Lanczos reduction can be used effectively for determining the thermal flux projectors and their time evolution as is required for evaluation of k(T).
Radiation from picosecond photoconductors in microstrip transmission lines

Signals radiated in the microstrip autocorrelation circuit are investigated using ion-bombarded InP photoconductors. A model and empirical data are presented which suggest that this circuit radiatively couples to itself, giving rise to what appears to be a "slow" signal in the autocorrelation data. It is demonstrated that with a judicious choice of electrode geometry, a subpicosecond signal radiated by the photoconducting gap can be separated from the slower signal radiated by the microstrip electrodes.
Properties of African squall lines inferred from time-lapse satellite imagery.

Abstract Analysis of 48 h of time-lapse satellite imagery of a family of squall lines in Africa links the phenomena with a characteristic cloud cluster and with a wind field perturbation which is enhanced in passing through an African easterly wave trough. A thin “are line” of low-level developing cumulus, a salient feature of the squall lines on the imagery, is shown to occur at the front boundary of the mesoscale/convective scale subsidence. Analysis of the wind field indicates that a squall line is associated with a vorticity center in the mid-level easterly flow which accompanies the mesoscale subsidence which, in turn, contributes to further forced ascent of subcloud air along the front of the squall line into convective towers which merge into an extensive anvil. The squall lines evolved through a life cycle of 6 to 12 h while the larger cloud cluster and wind perturbation lasted over 48 h. The magnitude of the vertical mass exchange suggests that squall-line families contribute significantly to the.
A Hybrid Electromagnetic Inversion Method Based on BI-GMM-GAMP and Convolutional Neural Network

Electromagnetic inverse scattering is a nonlinear and ill-posed problem. Some traditional algorithms have been proposed to solve it, but they cannot perform well in both terms of efficiency and accuracy. In order to reconstruct high quality images in real time, this paper presents a hybrid method which combines the Born iterative Gaussian mixture model generalized approximate message passing (BI-GMM-GAMP) algorithm with a convolutional neural network (CNN). To be specific, BI-GMM-GAMP is first used for obtaining the preliminary images. Subsequently, these pictures are used for training U-Net. Experiments show the validity of this method.
Overview in Technical Synthesis and Applications of Zr2AC (A= In, Sn, Pb, Al, S and Se) MAX phases: a brief review

oxidation resistance. The Zr 2 PbC MAX phases are elastic and electrically anisotropic in nature and appropriate for high temperature applications, optoelectronic devices, and coating materials. Studying the optical characteristics of the Zr 2 SeC has shown its potential for application as a shielding material in order to decrease the heating of solar. The Zr 2 SC is suitable for use in high-temperature technologies, such as thermal barrier coating material TBC. The Zr 2 AlC phase is the most attractive among all non-synthesizable ternary MAX phases, particularly for the nuclear industry. There are a lot of challenges during fabrication of the MAX phase, including synthesis temperature, the MAX phase purity, and the secondary phase (impurities). In harsh external conditions, the defect density has a substantial impact on the MAX phase's stability and thus, the methods of defect formation and migration have a considerable impact on the phases' radiation resistance and self-healing capabilities.
Financial Solidarity or Autonomy? How Gendered Wealth and Income Inequalities Influence Couples’ Money Management

It is well established that women have lower income and wealth levels than men. These inequalities are most pronounced within heterosexual couples and grow once partners get married and have children. Nevertheless, equality in controlling money within couples is highly valued and might ameliorate women’s disadvantages in income and wealth ownership. Previous research has focused on explaining gender wealth inequalities at the household level; less is known about the possible consequences of these inequalities on how couples manage their money. In this article, we investigate how income and wealth inequalities among couples are associated with joint or independent money management. In theoretical terms, we perceive money management systems as representing two different norms of reciprocity within couples for buffering income and wealth inequalities between partners, depending on the transferability of resources and their institutional regulation. We apply pooled logistic regression models to data from the German Socio‐Economic Panel Study. Our findings confirm that income and wealth are relevant but have opposite associations with couples’ money management strategies. While couples with unequal income constellations tend to pool their money, couples with unequal wealth constellations manage their money independently. Accordingly, couples seem to use labour income to buffer gender inequalities by sharing resources, thereby following the norm of partnership solidarity. In contrast, gender wealth inequalities are reproduced by keeping resources separate, thus representing the norm of financial autonomy.
Three-Dimensional Impression of Biomaterials for Alveolar Graft: Scoping Review

Craniofacial bone defects are one of the biggest clinical challenges in regenerative medicine, with secondary autologous bone grafting being the gold-standard technique. The development of new three-dimensional matrices intends to overcome the disadvantages of the gold-standard method. The aim of this paper is to put forth an in-depth review regarding the clinical efficiency of available 3D printed biomaterials for the correction of alveolar bone defects. A survey was carried out using the following databases: PubMed via Medline, Cochrane Library, Scopus, Web of Science, EMBASE, and gray literature. The inclusion criteria applied were the following: in vitro, in vivo, ex vivo, and clinical studies; and studies that assessed bone regeneration resorting to 3D printed biomaterials. The risk of bias of the in vitro and in vivo studies was performed using the guidelines for the reporting of pre-clinical studies on dental materials by Faggion Jr and the SYRCLE risk of bias tool, respectively. In total, 92 publications were included in the final sample. The most reported three-dimensional biomaterials were the PCL matrix, β-TCP matrix, and hydroxyapatite matrix. These biomaterials can be combined with different polymers and bioactive molecules such as rBMP-2. Most of the included studies had a high risk of bias. Despite the advances in the research on new three-dimensionally printed biomaterials in bone regeneration, the existing results are not sufficient to justify the application of these biomaterials in routine clinical practice.
A Robust Method for the Elaboration of SiO2-Based Colloidal Crystals as a Template for Inverse Opal Structures

Photonic crystals (PCs) are nanomaterials with photonic properties made up of periodically modulated dielectric materials that reflect light between a wavelength range located in the photonic band gap. Colloidal PCs (C-PC) have been proposed for several applications such as optical platforms for the formation of physical, chemical, and biological sensors based on a chromatic response to an external stimulus. In this work, a robust protocol for the elaboration of photonic crystals based on SiO2 particle (SP) deposition using the vertical lifting method was studied. A wide range of lifting speeds and particle suspension concentrations were investigated by evaluating the C-PC reflectance spectrum. Thinner and higher reflectance peaks were obtained with a decrease in the lifting speed and an increase in the SP concentrations up to certain values. Seven batches of twelve C-PCs employing a SP 3% suspension and a lifting speed of 0.28 µm/s were prepared to test the reproducibility of this method. Every C-PC fabricated in this assay has a wavelength peak in a range of 10 nm and a peak width lower than 90 nm. Inverse-opal polymeric films with a highly porous and interconnected morphology were obtained using the developed C-PC as a template. Overall, these results showed that reproducible colloidal crystals could be elaborated on a large scale with a simple apparatus in a short period, providing a step forward in the scale-up of the fabrication of photonic colloidal crystal and IO structures as those employed for the elaboration of photonic polymeric sensors.
Research on UWB Indoor Positioning System Based on TOF Combined Residual Weighting

The performance of TDOA positioning based on UWB is limited by the hyperbolic characteristics of TDOA, especially for tags away from the hyperbolic asymptote. Aiming at this problem, a new UWB indoor positioning system is proposed. Firstly, TOF ranging is adopted to build the positioning equations; then the weighted centroid algorithm of four base stations is presented to compute the initial rough position of the tag; and the residual weighting is introduced to optimize the initial tag position; then, the corresponding nonlinear positioning equations, which will be algebraically transformed to one distribution function, are solved, and the optimal tag coordinates can be obtained by the Newton iteration method. Simulation experiments have verified the positioning reliability of the proposed algorithm under different noise environments and for different tag positions.
Genome-Wide Characterization of the Mitogen-Activated Protein Kinase Gene Family and Their Expression Patterns in Response to Drought and Colletotrichum Gloeosporioides in Walnut (Juglans regia)

Mitogen-activated protein kinases (MAPKs) are a family of Ser/Thr (serine/threonine) protein kinases that play very important roles in plant responses to biotic and abiotic stressors. However, the MAPK gene family in the important crop walnut (Juglans regia L.) has been less well studied compared with other species. We discovered 25 JrMAPK members in the Juglans genome in this study. The JrMAPK gene family was separated into four subfamilies based on phylogenetic analysis, and members of the same subgroup had similar motifs and exons/introns. A variety of cis-acting elements, mainly related to the light response, growth and development, stress response, and hormone responses, were detected in the JrMAPK gene promoters. Collinearity analysis showed that purification selection was the main driving force in JrMAPK gene evolution, and segmental and tandem duplications played key roles in the expansion of the JrMAPK gene family. The RNA-Seq (RNA Sequencing) results indicated that many of the JrMAPK genes were expressed in response to different levels of Colletotrichum gloeosporioides infection. JrMAPK1, JrMAPK3, JrMAPK4, JrMAPK5, JrMAPK6, JrMAPK7, JrMAPK9, JrMAPK11, JrMAPK12, JrMAPK13, JrMAPK17, JrMAPK19, JrMAPK20, and JrMAPK21 were upregulated at the transcriptional level in response to the drought stress treatment. The results of this study will help in further investigations of the evolutionary history and biological functions of the MAPK gene family in walnut.
Second-harmonic generation from GaAs/AlAs vertical cavity

We have demonstrated second‐harmonic generation in a GaAs/AlAs vertical cavity grown on a (311)B GaAs substrate. Second‐harmonic light of 492 nm was observed and its efficiency was measured to be 1.4×10−4 %/W. The cavity confines high intensity of fundamental field, resulting in efficient second‐harmonic generation. Quasiphase matching was realized with the stacked GaAs/AlAs layers inside the cavity, which was designed taking into account the strong absorption of second‐harmonic power in GaAs layers. We show that conversion efficiency of the GaAs/AlAs vertical cavity could be more than 10%/W if the optimization is completed.
Fabrication of microcapsule arrays on chemically patterned surfaces via covalent linking

A method for fabricating arrays of microcapsules covalently immobilized onto chemically patterned substrates was developed. The core-shell microparticles with poly(allylamine hydrochloride) (PAH) as the outermost layer were obtained by layer-by-layer (LbL) assembly, which were further treated with glutaraldehyde to endow the particles with abundant aldehyde groups on their surfaces. The particles were then covalently coupled to the chemically patterned regions with amino groups created by microcontact printing (μCP). After dissolution of the core particles, arrays of the hollow microcapsules with unchanged structures were obtained. These arrays could stand rigorous environmental conditions of higher ionic strength, and lower and higher pH values. Thus, the technique could be possibly applied to exploiting chips of microcontainers or microreactors in sensing technology.
The nonstellar continuum of the Seyfert galaxy NGC 7213

The optical continuum of the nearby Seyfert galaxy NGC 7213 is decomposed into stellar and nonstellar components, and the spectrum at X-ray energies is derived from observations made with the Monitor Proportional Counter and the Imaging Proportional Counter aboard the Einstein Observatory. These results are used to obtain conclusions about the galaxy's column density and spectral index, covering fraction and visual extinction, and thermal emission. Ultraviolet, infrared, and radio observations published elsewhere are then combined with the new data to produce the overall continuum.
Onset of possible solitons in surface tension-driven convection

For a shallow liquid layer open to air, and subjected to a thermal gradient, threshold conditions are given for the onset of Korteweg-de Vries soliton excitation as the result of an instability triggered by the Marangoni effect, i.e., by the variation of the interfacial tension with temperature or, equivalently, concentration of a surfactant.
A comparison of several approximate algorithms for finding multiple (N-best) sentence hypotheses

The authors introduce a new, more efficient algorithm, the word-dependent N-best algorithm, for finding multiple sentence hypotheses. The proposed algorithm is based on the assumption that the beginning time of a word depends only on the preceding word. The authors compare this algorithm with two other algorithms for finding the N-best hypotheses: the exact sentence-dependent method and a computationally efficient lattice N-best method. Although the word-dependent algorithm is computationally much less expensive than the exact algorithm, it appears to result in the same accuracy. The lattice method, which is still more efficient, has a significantly higher error rate. It is demonstrated that algorithms that use Viterbi scoring have significantly higher error rates than those that use total likelihood scoring. <<ETX>>
