description: The recent electron recoil excess observed by XENON1T has a possible interpretation in terms of solar axions coupled to electrons. If such axions are still relativistic at recombination they would also leave a cosmic imprint in the form of an additional radiation component, parameterized by an effective neutrino number $ΔN_\text{eff}$. We explore minimal scenarios with a detectable signal in future CMB surveys: axions coupled democratically to all fermions, axion-electron coupling generated radiatively, the DFSZ framework for the QCD axion. The predicted $ΔN_\text{eff}$ is larger than $0.03-0.04$ for all cases, close to the $2σ$ forecasted sensitivity of CMB-S4 experiments. This opens the possibility of testing with cosmological observations the solar axion interpretation of the XENON1T excess.

description: The economic competitiveness of biobased industries is discussed by comparing the South relative to other regions of the United States and biomass as a feedstock source relative to fossil fuels such as coal and petroleum. An estimate of the biomass resource base is provided. Estimated changes in the agricultural sector over time resulting from the development of a large-scale biobased industry are reported, and a study on the potential to produce electricity from biomass compared with coal in the southern United States is reviewed. A biobased industry can increase net farm income and enhance economics development and job creation.

description: Before pandemic the world economy had a pre-crisis situation which was characterized by unprecedented imbalances in the global financial and economic system, the lack of growth in world GDP, which posed a real threat to the world economic order. Almost all global analysts predicted a global economic crisis at the end of 2019. For the first time since time immemorial, bank interest rates in all countries have dropped to unprecedented low levels. Often interest rates were 0% or even negative. The EU’s financial system has been so disfigured by the VAT tax that fraud with this tax has reached a scale far exceeding hundreds of billions EUR and in fact got out of control of the authorities.

description: Highly turbulent environments require firms to act entrepreneurially. The returns to entrepreneurial activities are known as entrepreneurial rents. Following the payments perspective, these rents are allocated to the entrepreneurial resources of the firm as factor payments. However, unlike other factor payments, little is known about how to value these types of rents. An analysis of the economics and management literature reveals that entrepreneurial rents are a return to alertness, subjective judgment, asset control, and uncertainty bearing. Furthermore, entrepreneurial rents are noncontractible and temporary. This paper introduces two complementary valuation models that capture these characteristics and that explicitly impute value to various entrepreneurial activities.

description: Cross sections from low-energy neutron-nucleus scattering have been evaluated using a coupled channel theory of scattering. Both a coordinate-space and a momentum-space formalism of that coupled-channel theory are considered.A simple rotational model of the channel interaction potentials is used to find results using two relevant codes, ECIS97 and MCAS, so that they may be compared. The very same model is then used in the MCAS approach to quantify the changes that occur when allowance is made for effects of the Pauli principle.

Electronic and magnetic properties of diiron in extended carbon networks Fe2C6 and Fe2C12 from first principles

Publisher: name: arXiv
Year: 2020
Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: From density functional DFT investigations helped with crystal chemistry rationale, diiron (pairs of Fe), mostly known in molecular diiron nona-carbonyl Fe2(CO)9 and diiron-mono-carbide Fe2C carbide, are embedded in hexagonal C6 substructures. Generated Fe2C6 and Fe2C12 are shown to be more cohesive than the mono-carbide on one hand, and increasingly cohesive from hexa- C6 to dodeca- C12 on the other hand. From energy differences, the ground state is spin-polarized SP, versus a non-spin-polarized NSP configuration, and identified as ferromagnetic versus a higher energy anti-ferromagnetic hypothesis. The projection of the magnetic charge density on Fe and C, shows that only Fe carries the magnetic moment, while carbon receives charges from Fe as illustrated by the electron localization function ELF 3D and 2D mapping. SP configuration induces an enlarged c/a hexagonal ratio, versus NSP, while a(hex.) remains constant thanks to the rigid C6 carbon substructure network, resulting in an anisotropic magneto-volume response. This feature, essentially due to in-plane diiron, is discussed from the energy-volume (E, V) NSP and SP equations of state EOS and derived quantities like volume- and d(Fe-Fe)- changes of the magnetization.

description: This paper introduces and defines the concept of collective entrepreneurship. A review of the defensive single-level rent-seeking objective of traditional agricultural cooperatives is introduced followed by an analysis of recent studies documenting a shift in the objective functions of producers jointly integrating toward more multiple-level rent-seeking entities. This process of shifting from market failure-ameliorating collective action mechanisms toward rent-seeking group action organizations is labeled collective entrepreneurship. The justification for introducing this concept is based on the Olsonian premise that rational, self-interested individuals will not act to achieve their common or group interests without coercion or selective incentives.
Model-Independent Perspectives on Coupled Dark Energy and the Swampland

description: We present a general model-independent approach to study the coupled dark energy and the string Swampland criteria. We show how the dark sector interaction is degenerated with the equation of state of dark energy in the context of the expansion of the Universe. With priors for either of them, the dynamics of dark energy and the dark sector interactions can be reconstructed together with the bounds of the Swampland criteria. Combining cosmic chronometers, baryon acoustic oscillation (BAO), and Type Ia supernovae our results suggest a mild $1 σ$ significance of dark sector interactions at low redshift for the coupled quintessence. The Lyman-$α$ BAO at $z=2.34$ leads a $2 σ$ signal of nonzero interactions at high redshift. The implications for coupled quintessence are discussed.

Why is the $3\times 3$ neutrino mixing matrix almost unitary in realistic seesaw models?

description: A simple extension of the standard model is to introduce $n$ heavy right-handed Majorana neutrinos and preserve its $\rm SU(2)^{}_L \times U(1)^{}_Y$ gauge symmetry. Diagonalizing the $(3+n) \times (3+n)$ neutrino mass matrix, we obtain an exact analytical expression for the effective mass matrix of $ν^{}_e$, $ν^{}_μ$ and $ν^{}_τ$. It turns out that the $3\times 3$ neutrino mixing matrix $V$, which appears in the leptonic charged-current weak interactions, must not be exactly unitary. The unitarity violation of $V$ is negligibly tiny, however, if the canonical seesaw mechanism works to reproduce the correct mass scale of light Majorana neutrinos. A similar conclusion can be drawn in the realistic Type-II seesaw models.

Experiential knowledge, moral agency and genetic testing for hereditary breast/ovarian cancer
Creators: name: D’Agincourt-Canning, Lorraine
Publisher: name: University of British Columbia
Year: 2009

description: This study examined the influence of genetic testing for hereditary breast/ovarian cancer on individuals' understandings of self and moral agency. Using an ethnographic design, the investigator conducted in-depth interviews with 53 individuals (45 female, eight male) from families at high-risk for hereditary breast/ovarian cancer. Working closely with genetic counsellors and geneticists at the Hereditary Cancer Program (HCP), BC Cancer Agency, she also undertook approximately 50 hours of fieldwork as an observer in genetic counselling sessions. In addition, she regularly attended clinical review and steering meetings of the HCP. The research focused primarily on the accounts of at-risk individuals who underwent testing and those who were eligible but declined testing. The impact of genetic information was examined through three interrelated aspects of self: the embodied, relational and social self. Most participants linked their positive results to becoming more aware of their embodied selves. The information was generally viewed as enabling; it allowed participants to take measures (surveillance or prophylactic surgery) to confront the disease. However, for a small minority of women knowledge about their genetic risk had a profound and limiting effect on their agency. Rather than giving them a sense control, they saw little opportunity to fight the disease. They were overcome by thoughts of their embodied risk and a dire future from which they could not escape. A few others were thrust into a state of uncertainty. These participants did not view themselves as risk-free, yet neither did they perceive themselves as unhealthy. While worrisome at times, knowledge of their mutation status became part of their awareness, part of their routine lives and ultimately part of who they were.

description: To understand the factors that influence farm direct marketing, a linear regression model is estimated to test the relationships between county-level direct market sales and socioeconomic, agricultural production, and location characteristics for West Virginia. The results show that higher median housing value, increased population density, a younger population, a greater number of direct market farms, more diversity of fruit and vegetable production and closer proximity to Washington, D.C., increase direct market sales. The results have implications for other states with a large proportion of small and part-time farmers, many of whom are located in close proximity to metropolitan areas.

description: We elaborate on the proposal of [Phys. Rev.

We build a differential equation ruling the time evolution of $\langle K\rangle$, the spatial average of the expansion scalar. Supposing that the solution $\langle K\rangle = 0$ exists despite the presence of a large cosmological constant $Λ$, we show that such solution seems to be unstable.

description: We show that very large nonlocal nonlinear interactions between pairs of colliding slow-light pulses can be realized in atomic vapors in the regime of electromagnetically induced transparency. These nonlinearities are mediated by strong, long-range dipole--dipole interactions between Rydberg states of the multi-level atoms in a ladder configuration. In contrast to previously studied schemes, this mechanism can yield a homogeneous conditional phase shift of pi even for weakly focused single-photon pulses, thereby allowing a deterministic realization of the photonic phase gate.

description: The growth of abnormal cells in the brain's tissue causes brain tumors. Brain tumors are considered one of the most dangerous disorders in children and adults. It develops quickly, and the patient's survival prospects are slim if not appropriately treated. Proper treatment planning and precise diagnoses are essential to improving a patient's life expectancy. Brain tumors are mainly diagnosed using magnetic resonance imaging (MRI). As part of a convolution neural network (CNN)-based illustration, an architecture containing five convolution layers, five max-pooling layers, a Flatten layer, and two dense layers has been proposed for detecting brain tumors from MRI images. The proposed model includes an automatic feature extractor, modified hidden layer architecture, and activation function. Several test cases were performed, and the proposed model achieved 98.6% accuracy and 97.8% precision score with a low cross-entropy rate. Compared with other approaches such as adjacent feature propagation network (AFPNet), mask region-based CNN (mask RCNN), YOLOv5, and Fourier CNN (FCNN), the proposed model has performed better in detecting brain tumors.

description: Is entrepreneurship an innate ability or an acquired skill? Can entrepreneurship acumen be achieved and enhanced through education and training, or are certain people “born” to be entrepreneurs or to act entrepreneurially? Economists and management theorists give widely divergent answers to these questions. This paper reviews the major approaches to teaching entrepreneurship, primarily at the undergraduate level, and relates them to economic theories of entrepreneurship. Surprisingly, we find little connection between the leading approaches to entrepreneurship education and economists’ understanding of the entrepreneurial function. We assess likely explanations for the lack of contact between these two groups of scholars and suggest possible improvements.

description: Tri-gate ferroelectric FETs with Hf0.5Zr0.5O2 gate insulator for memory and neuromorphic applications are fabricated and characterized for multi-level operation. The conductance and threshold voltage exhibit highly linear and symmetric characteristics. A compact analytical model is developed to accurately capture FET transfer characteristics, including series resistance, coulombic scattering, and vertical field dependent mobility degradation effects, as well as the evolvement of threshold voltage and mobility with ferroelectric polarization switching. The model covers both sub-threshold and strong inversion operation. Additional measurements confirm ferroelectric switching as opposed to carrier-trapping-based memory operation. The compact model is implemented in a simulation platform for online training of deep neural networks.

description: We study creation of entanglement and quantum steering in a parity-time- (PT -) symmetric cavity magnomechanical system. There is magnetic dipole interaction between the cavity and photon-magnon, and there is also magnetostrictive interaction which is induced by the phononmagnon coupling in this system. By introducing blue-detuned driving microwave field to the system, the bipartite entanglement of the system with PT -symmetry is significantly enhanced versus the case in the conventional cavity magnomechanical systems (loss-loss systems). Moreover, the one-way quantum steering between magnon-phonon and photon-phonon modes can be obtained in the unbroken-PT -symmetric regime. The boundary of stability is demonstrated and this show that the steady-state solutions are more stable in the gain and loss systems. This work opens up a route to explore the characteristics of quantum entanglement and steering in magnomechanical systems, which might have potential applications in quantum state engineering and quantum information.

description: The purpose of this study was to identify the factors influencing productive activities of the Korean rural elderly. Utilizing data from the 2004 survey "Living Profile and Welfare Service Needs of Older Persons in Korea," this study predicted the productive activities of the rural elderly. All of the ten predicting variables selected from the survey and literature review (age, gender, education, activity limitation, personal income, health, organization, family status, socio-economic status, and job) were found to have significant partial effects on such productive activities as paid work, care-giving and volunteer work. The following are major conclusions: The rural elderly women had more care-giving, whereas men had more volunteer work. Participation in religious or social organizations was a good predictor for participation in a volunteer work. Single-family status was a negative factor for care-giving. Being a farmer or not could explain the paid working time most effectively. The rural elderly with a relatively high socio-economic status have more inclination to participate in a volunteer work. Aging reduces the possibility of sharing the experiences of paid work or care-giving. Activity limitation had a negative partial effect on care-giving. Good health was the only valuable predictor for all kinds of productive activities. Personal income was positively related with paid work and care-giving. The highly educated were more likely to do unpaid productive work.

description: Ultrafast laser excitation can trigger multiplex coherent dynamics in molecules. Here, we report attosecond transient absorption experiments addressing simultaneous probing of electronic and vibrational dynamics in a prototype molecule, deuterium bromide (DBr), following its strong-field ionization. Electronic and vibrational coherences in the ionic X$^2Π_{3/2}$ and X$^2Π_{1/2}$ states are characterized in the Br-$3d$ core-level absorption spectra via quantum beats with 12.6-fs and 19.9-fs periodicities, respectively. Polarization scans reveal that the phase of the electronic quantum beats depends on the probe direction, experimentally showing that the coherent electronic motion corresponds to the oscillation of the hole density along the ionization-field direction. The vibrational quantum beats are found to maintain a relatively constant amplitude, whereas the electronic quantum beats exhibit a partial decrease in time. Quantum wave-packet simulations show that the decoherence effect from the vibrational motion is insignificant because of the parallel relation between the X$^2Π_{3/2}$ and X$^2Π_{1/2}$ potentials. A comparison between the DBr and HBr results suggests that rotation motion is responsible for the decoherence since it leads to initial alignment prepared by the strong-field ionization.

description: Military nursing encompasses complex roles such as leadership, management, and supervision, requiring a specific set of competencies. This descriptive study aims to analyze the competency levels of Nurse Corps Officers within the Armed Forces of the Philippines (AFP). Using the 2020 Competencies Assessment Tool developed by the American College of Healthcare Executives (ACHE), this study evaluates five core competency domains at the Victoriano Luna Medical Center. The study aims to assess the skills and performance of AFP Nurse Corps Officers in Nursing Service Management. Specific objectives include profiling the officers’ education level, rank, and service tenure; evaluating competencies in communication, leadership, professionalism, healthcare environment knowledge, and administrative skills; identifying competency gaps; and proposing strategies for improvement. This descriptive research utilizes a quantitative approach, surveying 50 Nurse Corps Officers at VLMC. A Likert scale questionnaire assessed competency levels in various domains, with responses categorized from highly competent to not competent. Findings indicate that most respondents are moderately proficient in communication and relationship management, essential for effective teamwork and adaptation. However, service introduction and innovation scored lowest. The study highlights the importance of continuous management training to enhance skills and competencies. Nurse Corps Officers exhibit strong adaptability and adherence to standards but require further development in innovation and research. Continuous education and cross-sector collaboration are essential for improving nursing management competencies.

description: This paper aims to review the role of farm households and the agro-food sector in the economy of rural areas in Korea. It discusses definition of rural area, share of agricultural and agro-food sectors in Korean economy, the income situation of farm households and non-farming activities, and multiplier effects of agriculture in Korea. Rural areas mean Eup and Myeon, whereas Dong means urban area. Rural population in Korea has continued to decrease over the years. In 2005, 18.3% of total land area, or 1,824thousand ha, was used for paddy and dry fields. The share of GRDP of agricultural, forestry, and fishing sectors was about 10% in 1985, but dropped to slightly over 3% in 2005. Thirty seven percent of farmers have a second employment in the non-farm sector and 67.2% of part-time farmers are more devoted to their non-farm activities than farming for farm household income. Rural tourism provides diverse opportunities for rural and urban residents to exchange products, services, information, and culture. New demands are arising toward rural areas: leisure and relaxation spaces, rural tourism, nature and ecology, rural amenity, and safe and fresh local foods.

description: Users’ experiences in mental health assessment are multifaceted, including their emotional experiences. Yet, studies of mobile apps for psychiatric assessment have centered on diagnostic accuracy and perceived usability, with little consideration of the impact of user emotional experiences. In this study, we focused on users’ perceived usability and emotions and compared the user experience of a paper-and-pencil and an app-based collection of mental health screening questionnaires: EarlyDetect. The System Usability Scale (SUS) and modality-directed emotion questionnaires were administered using paper-and-pencil or iPad. Modality was assigned pseudo-randomly on patients’ first visit at a referral-based mental health clinic. We found that patients assigned to the iPad app reported a significantly higher SUS score than patients assigned to paper-and-pencil, qualified by a modality-by-gender interaction where modality effects were significant for men but not for women. Moreover, enjoyment was positively linked to perceived usability, whereas boredom, frustration, and anxiety were negatively linked to usability. Our findings illustrate the added value of studying user experience applied to psychiatric assessments, where both emotions and gender-specific user experience should be taken into consideration. We further discuss the implications for psychiatric assessments via app versus traditional data collection.

description: This study estimates farmers' risk attitudes in Missouri using a non-structural approach over time. The non-structural approach proposed by Antle (1989) allows for multiple outputs and various types of risk faced by farmers and doesn't require specific functional forms for utility or production. This approach can also provide farmers' risk attitudes over time. The results show that farmers' risk attitudes are risk loving and change over time, while farmers' risk attitude is generally assumed to be risk averse and very stable over time. Since this approach has the different definition of risk attitude, the results of this study may be a bit different from previous studies.

description: The study explores a long memory conditional volatility model on international grain markets, demonstrating importance of modeling both temporal effects of volatility and long memory process. This study adopts six different volatility models, nested in an ARMA(p,q)- FIGARCH(P,D,Q), to capture dependence of grain cash price volatility and compares the performance of the six models. It also visits a related question about non-normal behaviors of grain prices and adopts the student-t density intended to account for fat-tailed properties of the data. We find suitability of the FIGARCH type models under the student-t distribution and competitiveness of the parsimonious FIGARCH(1,d,0) for modeling long memory volatility.

description: We study top quark pair productions at a polarized photon collider from an e(+)e(-) linear collider (LC) in various improved technicolor model, namely, the one-family walking technicolor model, the top-color-assisted technicolor model, and the top-color-assisted multiscale technicolor model. Recent constraint on the top-pion mass from the precision data of R(b) is considered. It is shown that, considering only the statistical errors, a polarized photon collider from a 500 GeV LC with an integrated luminosity of 500 inverse fb is sufficient for distinguishing the three improved technicolor models experimentally.

Ordering for Communication-Efficient Quickest Change Detection in a Decomposable Graphical Model

description: A quickest change detection problem is considered in a sensor network with observations whose statistical dependency structure across the sensors before and after the change is described by a decomposable graphical model (DGM). Distributed computation methods for this problem are proposed that are capable of producing the optimum centralized test statistic. The DGM leads to the proper way to collect nodes into local groups equivalent to cliques in the graph, such that a clique statistic which summarizes all the clique sensor data can be computed within each clique. The clique statistics are transmitted to a decision maker to produce the optimum centralized test statistic. In order to further improve communication efficiency, an ordered transmission approach is proposed where transmissions of the clique statistics to the fusion center are ordered and then adaptively halted when sufficient information is accumulated. This procedure is always guaranteed to provide the optimal change detection performance, despite not transmitting all the statistics from all the cliques. A lower bound on the average number of transmissions saved by ordered transmissions is provided and for the case where the change seldom occurs the lower bound approaches approximately half the number of cliques provided a well behaved distance measure between the distributions of the sensor observations before and after the change is sufficiently large. We also extend the approach to the case when the graph structure is different under each hypothesis. Numerical results show significant savings using the ordered transmission approach and validate the theoretical findings.
Energy Crop Production Costs and Breakeven Prices Under Minnesota Conditions

description: Production costs and breakeven prices were calculated for four energy crops plus corn stover. The energy crop breakeven prices were calculated under two different scenarios regarding land costs and the opportunity costs of not utilizing the land for some other competing land use. One scenario is that the competing land use is pasture. The other is that the energy crops would compete with grain crops on more expensive land, and would need to provide a return over land costs equal to returns on the grain crops. Corn stover would be the cheapest of the energy biomass sources considered, at $50/ton to cover the additional machinery costs to shred, rake, bale, and transport 25 miles to a processing plant. Aside from stover, a grassland crop under high fertilization with a 4-ton yield has the lowest cost at $77/ton of dry matter. A grassland crop under low fertilization with a 2-ton yield but a longer stand life has the highest cost at $110/ton. Hybrid poplar comes in at $81/ton. Willow is at an early stage of development in Minnesota, but it would be the cheapest energy crop at $72/ton if it achieves a 5-ton yield with a 23-year stand life that has been reported in New York. These costs are based on the pasture land rental rate of $40/acre. The more expensive grain crop land translates directly into higher energy crop breakeven prices which are also presented in the paper.

description: Given a distribution of pebbles on the vertices of a graph G, a {\it pebbling move} takes two pebbles from one vertex and puts one on a neighboring vertex. The {\it pebbling number} Π(G) is the minimum k such that for every distribution of k pebbles and every vertex r, it is possible to move a pebble to r. The {\it optimal pebbling number} Π_{OPT}(G) is the minimum k such that some distribution of k pebbles permits reaching each vertex. We give short proofs of prior results on these parameters for paths, cycles, trees, and hypercubes, a new linear-time algorithm for computing Π(G) on trees, and new results on Π_{OPT}(G). If G is a connected n-vertex graph, then Π_{OPT}(G)\le\ceiling{2n/3}, with equality for paths and cycles. If \bf{G} is the family of n-vertex connected graphs with minimum degree k, then 2.4\le \max_{G\in \bf{G}} Π_{OPT}(G) \frac{k+1}{n}\le 4 when k>15 and k is a multiple of 3. Finally, Π_{OPT}(G)\le 4^tn/((k-1)^t+4^t) when G is a connected n-vertex graph with minimum degree k and girth at least 2t+1. For t=2, a more precise version of this last bound is Π_{OPT}(G)\le 16n/(k^2+17).

Neu für Burgenland. Fehlt in FRANZ (1989). Die grosswüchsige Art gehört nach POVOLNY & al. (2003) zu den karpato-endemischen Fleischfliegenarten. Der einzige bislang bekannte Fundort ausserhalb der Karpaten lag bislang am Eichkogel in NÖ. Offenbar scheint die Art auch im Leithagebirge eine kräftige Kolonie zu besitzen, wie die zahlreichen Funde in Hornstein beweisen.

description: As a first effort at modeling nonalcoholic beverage demand in a systemwide framework that includes bottled water, this article examines the impact of advertising on the demand for nonalcoholic beverages in the United States. We employed an AIDS (almost ideal demand system) model of five jointly estimated equations that included advertising expenditures as explanatory variables to evaluate annual U.S. consumption of nonalcoholic beverages for 1974 through 2005. Results suggest that advertising increases demand for fluid milk, soft drinks, and coffee and tea, but not for juice or bottled water. Advertising spillover effects occur in over 50 percent of the cases considered, and such effects can be substantial, particularly for advertising of soft drinks, and coffee and tea. We find that a large increase in the retail price of fluid milk, an increasing trend towards dining out, and positive spillover effects from soft drink advertising made significant contributions to bottled water’s success in recent years.

description: Follow-up serves an important role in the management of pulmonary nodules for lung cancer. Imaging diagnostic guidelines with expert consensus have been made to help radiologists make clinical decision for each patient. However, tumor growth is such a complicated process that it is difficult to stratify high-risk nodules from low-risk ones based on morphologic characteristics. On the other hand, recent deep learning studies using convolutional neural networks (CNNs) to predict the malignancy score of nodules, only provides clinicians with black-box predictions. To this end, we propose a unified framework, named Nodule Follow-Up Prediction Network (NoFoNet), which predicts the growth of pulmonary nodules with high-quality visual appearances and accurate quantitative results, given any time interval from baseline observations. It is achieved by predicting future displacement field of each voxel with a WarpNet. A TextureNet is further developed to refine textural details of WarpNet outputs. We also introduce techniques including Temporal Encoding Module and Warp Segmentation Loss to encourage time-aware and shape-aware representation learning. We build an in-house follow-up dataset from two medical centers to validate the effectiveness of the proposed method. NoFoNet significantly outperforms direct prediction by a U-Net in terms of visual quality; more importantly, it demonstrates accurate differentiating performance between high- and low-risk nodules. Our promising results suggest the potentials in computer aided intervention for lung nodule management.
