description: Beneath the fusion-encrusted surfaces of the most primitive stony meteorites lies not homogeneous rock, but a profusion of millimeter-sized igneous spheres. These chondrules, and their centimeter-sized counterparts, the calcium-aluminum-rich inclusions, comprise more than half of the volume fraction of chondritic meteorites. They are the oldest creations of the solar system. Their chemical composition matches that of the solar photosphere in all but the most volatile of elements, reflecting their condensation from the same pristine gas that formed the sun. In this invited editorial, we review the nebular shock wave model of Desch and Connolly (Meteoritics and Planetary Science 2002, 37, 183) that seeks to explain their origin. While the model succeeds in reproducing the unique petrological signatures of chondrules, the origin of the required shock waves in protoplanetary disks remains a mystery. Outstanding questions are summarized, with attention paid briefly to competing models.

description: Operator-theoretic analysis of nonlinear dynamical systems has attracted much attention in a variety of engineering and scientific fields, endowed with practical estimation methods using data such as dynamic mode decomposition. In this paper, we address a lifted representation of nonlinear dynamical systems with random noise based on transfer operators, and develop a novel Krylov subspace method for estimating the operators using finite data, with consideration of the unboundedness of operators. For this purpose, we first consider Perron-Frobenius operators with kernel-mean embeddings for such systems. We then extend the Arnoldi method, which is the most classical type of Kryov subspace method, so that it can be applied to the current case. Meanwhile, the Arnoldi method requires the assumption that the operator is bounded, which is not necessarily satisfied for transfer operators on nonlinear systems. We accordingly develop the shift-invert Arnoldi method for Perron-Frobenius operators to avoid this problem. Also, we describe an approach of evaluating predictive accuracy by estimated operators on the basis of the maximum mean discrepancy, which is applicable, for example, to anomaly detection in complex systems. The empirical performance of our methods is investigated using synthetic and real-world healthcare data.

description: We empirically demonstrate that graphical models can be a valuable tool in the identification of mediating variables in causal pathways. We make use of graphical models to elucidate the causal pathway through which the treatment influences the levels of fatigue and weakness in people living with HIV (PLHIV) based on a secondary analysis of a categorical dataset collected in a behavioral clinical trial: is weakness a mediator for the treatment and fatigue, or is fatigue a mediator for the treatment and weakness? Causal mediation analysis could not offer any definite answers to these questions.

description: In this article, we report on the development of a time-of-flight based electron energy analyzer capable of measuring the 3-D momentum and energy distributions of very low energy (meV-scale) photoemitted electrons. This analyzer is capable of measuring energy and 3-D momentum distributions of electrons with energies down to 1 meV with a sub-meV energy resolution. This analyzer is an ideal tool for studying photoemission processes very close to the photoemission threshold and also for studying the physics of photoemission based electron sources.

Subjects: Corporate governance, Risk management committee, Board of directors' independence and Bankruptcy risk

description: This study determined the effect of corporate governance on bankruptcy risk in commercial banks in Nigeria, using risk management committee and board of directors’ independence. Ex Post Facto research design was adopted for the study. A sample of eight deposit money banks was used for the study. Data were obtained from the annual reports and audited accounts of the banks under assessment. Altman's original model for public companies was used to extract data and the formulated hypotheses were tested with regression analysis with aid of E-View 9.0.  The analysis and hypotheses tested shows that risk management committee has no significant effect on bankruptcy risk commercial banks in Nigeria. However, the study revealed that board of directors’ independence has a positive significant effect on bankruptcy risk commercial banks in Nigeria. Based on the results, the study recommended among others that risk management committee should be encouraged, since the committee can influence the capacity for problem-solving as the variety of perspectives that identifying the weakness of internal control and risk source that can easily use in checkmating bankruptcy

 Priocnemis ursula Banks, 1944, Bulletin of the Museum of Comparative Zoology, vol. 94, p. 184–185 [Holotype: ♀, DOMINICAN REPUBLIC, Villa Altagracia (MCZC)].
 Diagnosis. This species can be separated from other Ageniella species in the Dominican Republic by having the integument black; the antenna is brown, orange beneath; the pubescence on the body is long and golden, longer and more abundant on the propodeum (Fig. 4J); the clypeus is trapezoidal and orange (Fig. 1G); the pronotum has the collar differentiated from the disc; the first metasomal segment is not carinate; the dorsal face of hind tibia has small and thin spines; the mid tibia has spines; and the fore and hind wings are subtranslucent. The male of this species remains unknown.
 Material examined. DOMINICAN REPUBLIC: Pedernales, Sierra de Baoruco, Aceitillar, 25.2 km ENE Pedernales, 18–05–29N, 71–31–16W, 1271 m, dense broadleaf forest, pine, yellow pan trap, sample 42262, C.

VII–4.VIII.1995, (EMUS).
 Distribution. Dominican Republic.
 Host. Unknown.
 Remarks. This species is morphologically similar to A. salti (Banks); A. salti also is found in the Caribbean (Cuba). Ageniella ursula differs from A. salti in having the face black, contrasting with clypeus and mandibles, which are reddish-orange. Individuals of A. salti from Cuba and USA are blackish, with the face, clypeus, and mouthparts reddish-black, as noted by Alayo (1969) and Townes (1957). Ageniella salti has the metasoma as reddish-black as the face (Alayo 1969), while A. ursula has legs and metasoma black, with almost inconspicuous reddish-black reflections. Males of A. salti are known and A. ursula males may prove to be similar to this species. Ageniella ursula is endemic to the Dominican Republic (Perez-Gelabert 2008).

description: This paper models producers’ interdependent incentives to participate in a voluntary livestock disease control program. Under strategic complementarity among participation decisions, after a slow start momentum can build such that market premium for participation and participation rate increase sequentially. Non-participation, partial participation and full participation can all be Nash equilibria while participation cost heterogeneity will dispose the outcome toward incomplete participation. We find plausible conditions under which temporary government subsidies to the least cost-effective producers causes tipping toward full participation. Applying parameters from the literature on Johnes’ disease, we illustrate factors that may affect participation. These include cost heterogeneity and program effectiveness.
A generalization of Filliman duality
Creators: name: Kuperberg, Greg
Publisher: name: arXiv
Year: 2001
Subjects: subject: Metric Geometry (math.MG)

subject: FOS: Mathematics

description: Filliman duality expresses (the characteristic measure of) a convex polytope P containing the origin as an alternating sum of simplices that share supporting hyperplanes with P. The terms in the alternating sum are given by a triangulation of the polar body P^o. The duality can lead to useful formulas for the volume of P. A limiting case called Lawrence's algorithm can be used to compute the Fourier transform of P. In this note we extend Filliman duality to an involution on the space of polytopal measures on a finite-dimensional vector space, excluding polytopes that have a supporting hyperplane coplanar with the origin. As a special case, if P is a convex polytope containing the origin, any realization of P^o as a linear combination of simplices leads to a dual realization of P.

description: Thermally emitting X-ray isolated neutron stars represent excellent targets for testing cooling surface emission and atmosphere models, which are used to infer physical parameters of the neutron star. Among the seven known members of this class, RX J1605.3+3249 is the only one that still lacks confirmation of its spin period. Here we analyze NICER and XMM-Newton observations of RX J1605.3+3249, in order to address its timing and spectral behavior. Contrary to a previous tentative detection, but in agreement with the recent work by Pires et al. (2019), we find no significant pulsation with pulsed fraction higher than 1.3% (3σ) for periods above 150 ms. We also find a limit of 2.6% for periods above 2 ms, despite searches in different energy bands. The X-ray spectrum can be fit by either a double-blackbody model or by a single-temperature magnetized atmosphere model, both modified by a Gaussian absorption line at ~0.44 keV. The origin of the absorption feature as a proton cyclotron line or as an atomic transition in the neutron star atmosphere is discussed. The predictions of the best-fit X-ray models extended to IR, optical and UV bands are compared with archival data. Our results are interpreted in the framework of a fallback disk scenario.

description: Persons 60 years and older are much more likely than younger people to rate their health as fair or poor and to have difficulties with daily activities. Among the elderly, nonmetro residents are more likely to have poor health status than their metro counterparts. Larger proportions of the nonmetro elderly have less than a high school education and income below $20,000—factors that contribute to their higher incidence of poor health.

description: The Bahamas has made tourism the country’s primary economic force. Tourism comprises approximately half of gross domestic product while agriculture comprises approximately three percent. The Bahamas has a lack of development in other sectors of the economy, (e.g. agriculture), putting the country at a global disadvantage. In order for The Bahamas to compete globally there has to be some level of food security and a larger share of alternative venues of economic activity. The lack of connection between the local farming community and the hospitality industry has been identified as one of the main areas that can potentially ease the over reliance on foreign foodstuffs. This paper is based on data from tourist surveys, interviews and personal observation. A classification model of agritourism enterprises is introduced and important linkages between agriculture and tourism are examined. This research investigated three varying agritourism enterprises as modern developments in agriculture and prospects for developing an economic diversification strategy for The Bahamas, utilizing agritourism. The research observed that the greatest barriers to agritourism were on the supply side. Issues such as: lack of government interest, policy, farming labor and funding were key barriers for the farmers’ perspective whereas elites touted low production and limited farmer reliability as barriers. Bureaucrats and academics found lack of policy, limited amount of farmers and lack of resources (technical, financial, infrastructure) as obstacles. This research has revealed that agritourism can be a success with careful planning, market determination and strong marketing coupled with the will to adapt and remain flexible.

description: Climate change is projected to affect the flow regime in urban waterways adversely. This study investigates the climate change impacts on the flow regime in the Lucas Creek catchment under three Representative Concentration Pathways (RCPs): RCP 2.6, RCP 4.5 and RCP 8.5. Flow Duration Curves (FDCs) and Indicators of Hydrological Alteration (IHA) methods are used to assess flow regime variations. Results of FDCs show a maximum rise of 370% in peak flow under RCP 4.5 however, low flow increases by 40%. Monthly streamflow increases up to 380% except for October and December. Similarly, the majority of the IHA parameters also show at least a 10% increase in their magnitudes under RCP 8.5. However, some parameters such as high pulse duration and rise rate decrease by 50% under RCP 4.5. The catchment would mainly suffer severe impact variations under RCP 4.5 and RCP 8.5 in the future.

description: As e-commerce platforms continue to expand, understanding consumer behavior has become crucial for enhancing customer satisfaction and driving business success. Recommendation systems play a pivotal role in predicting consumer preferences and delivering personalized product suggestions. This paper presents an extensive literature review on recommendation techniques, including collaborative filtering, content-based approaches, and hybrid models. Notable advancements, such as the use of deep learning, trust-based filtering, and context-aware models, are highlighted. Building on these foundations, we propose a novel model that integrates advanced machine learning algorithms with consumer behavior analysis to predict preferences more accurately. The expected results suggest that this model will improve the precision of recommendations, effectively addressing challenges like data sparsity and evolving user preferences and enhancing overall customer engagement in e-commerce environments

description: T-cell activation plays a critical role in the initiation and propagation of HIV-1 infection and yet transient activation of the immune system is a normal response to immunization. In this study we extend a simple of model of HIV infection to include T cell activation by vaccination. We then show that the model can reproduce many but not all of the features of the post-tetanus immunization rise in viral load observed and reported on by Stanley et al., [N. Engl. J. Med., 334:1222--1230 (1996)]. Amplitudes and approximate timing of post-immunization maximum viremia were matched in nine of twelve cases; in patients with double peaks of nearly equal amplitude the later peaks were matched. Patients with single early peaks in their viremia were best fit with relatively high antigen clearance rate constants, while patients with early and late peaks in viremia of equal or nearly equal amplitude were best-fit with much lower clearance rates. The rate of clearance may depend on the level of pre-existing antibody, which in turn would be expected to depend on the time since the individual under study received a previous tetanus vaccination.

description: Following on our purpose of developing a unified pipeline for large-scale structure data analysis with angular (i.e. harmonic-space) power spectra, we now include the weak lensing effect of magnification bias on galaxy clustering in a publicly available, modular parameter estimation code. We thus forecast constraints on the parameters of the concordance cosmological model, dark energy, and modified gravity theories from galaxy clustering tomographic angular power spectra. We find that a correct modelling of magnification is crucial in order not to bias the estimation of cosmological parameters, especially in the case of deep galaxy surveys. Our case study adopts specifications of the Evolutionary Map of the Universe (EMU), which is a full-sky, deep radio-continuum survey, and is expected to probe the Universe up to redshift $z\sim6$. We assume the Limber approximation, and include magnification bias on top of density fluctuations and redshift-space distortions. By restricting our analysis to the regime where the Limber approximation holds true, we significantly minimise the computational time needed, compared to that of the exact calculation. We also show that there is a trend for more biased parameter estimates from neglecting magnification when the redshift bins are very wide. We conclude that this result implies a strong dependence on the lensing contribution, which is an integrated effect and becomes dominant when wide redshift bins are considered. Finally, we note that instead of being considered a contaminant, magnification bias encodes important cosmological information, and its inclusion leads to an alleviation of the degeneracy between the galaxy bias and the amplitude normalisation of the matter fluctuations.

description: Pulsar studies in the recent years have shown, more than others, to have benefited from a multi-wavelength approach. The INAF - Astronomical Observatory in Cagliari (INAF-OAC) is a growing facility with a young group devoted to pulsar and fast transients studies across the electromagnetic spectrum. Taking advantage of this expertise we have worked to provide a suite of multi-wavelength software and databases for the observations of pulsars and compact Galactic objects at the Sardinia Radio Telescope (SRT). In turn, radio pulsar observations at SRT will be made available, in a processed format, to gamma-ray searches using AGILE and Fermi gamma-ray satellite and, in a near future, they will be complementary to polarimetric X-ray observations with IXPE.

Taking the case of micro-credit of China Foundation for Poverty Alleviation, we measure the current situation of sustainable development of micro-credit. As far as we are concerned, the composite index of sustainable development of micro-credit shows the growth trend on the whole. Finally, in order to further improve the sustainable development of micro-credit, provide farmers with better financial services and enable more farmers to benefit from micro-credit, we put forth the following recommendations: strengthening technological innovation to reduce costs and improve operating efficiency and profitability of the micro-credit; strengthening risk control to improve the quality of loans; providing all-around non-financial services to lay the foundation for the sustainable development of micro-credit; setting an appropriate level of interest rates to improve the profitability of the institutions.

description: We propose an exact quantization of two-dimensional Jackiw-Teitelboim (JT) gravity by formulating the JT gravity theory as a 2D gauge theory placed in the presence of a loop defect. The gauge group is a certain central extension of $PSL(2, \mathbb{R})$ by $\mathbb{R}$. We find that the exact partition function of our theory when placed on a Euclidean disk matches precisely the finite temperature partition function of the Schwarzian theory. We show that observables on both sides are also precisely matched: correlation functions of boundary-anchored Wilson lines in the bulk are given by those of bi-local operators in the Schwarzian theory. In the gravitational context, the Wilson lines are shown to be equivalent to the world-lines of massive particles in the metric formulation of JT gravity.

description: Most of the papers published in Agricultural Economics Research originate either within the Bureau of Agricultural Economics itself or in projects carried on cooperatively with the State Agricultural Colleges. This is not an inviolable rule, however, and this issue contains two exceptions to it: the present article and another, farther on, by Messrs. Todd and Zirkle of the Forest Service. In both cases, of course, the subject matter appears to be of especial interest to workers within the Bureau. This article summarizes a study which was planned and carried forward by Messrs. Baker and Paarlberg as a part of Baker's graduate work at Purdue. Several of us in the Bureau were acquainted with the fact that the study was under way and we not only supplied Mr. Baker with some of his Agricultural Situation references which were used as the source of the forecasts but also had some opportunity to discuss concepts and methods. The subject matter is of such a direct and immediate interest to all those interested in agricultural outlook work that we believed it warranted an invitation too Messrs. Baker and Paarlberg to prepare this article. As was indicated in the forward to James P. Cavin's "Forecasting the Demand for Agricultural Products" in the July issue, we need more appraisal and criticism of our forecasting results rather than less; and this is in effect a companion to Cavin's analysis, as this article evaluates the accuracy of our forecasting results while Mr. Cavin's article dealt chiefly with methods by which the forecasts are derived.

Ageniella violaceipes

description: Ageniella (Ageniella) violaceipes (Cresson, 1865)
(Fig. 4I)
 Pompilus violaceipes Cresson, 1865, Entomological Society of Philadelphia, vol. 4, p. 129 [Holotype: ♀, CUBA (ANSP)].
 Diagnosis. This species can be separated from other Ageniella species in the Dominican Republic by having the integument black on the head and pleura, orange on the dorsum of mesosoma and metasoma, and purplish reflections on the legs and pronotum (Fig. 4I). Additionally, the antenna is brown with purplish reflections on the first segments; the pubescence on the body is short and reddish, with sparse long setae; the clypeus is trapezoidal; the first metasomal segment is not carinate; the dorsal face of hind tibia has small spines; the mid tibia has spines; and the fore and hind wings are darkened with slight purple reflections. The male of this species remains unknown.
 Material examined. DOMINICAN REPUBLIC: 1 ♀, Pedernales, La Abeja, 38 km NNW Cabo Rojo, (18–09N, 71–38W), 1250 m, J Rawlins and R. Davidson col., 15.VII.1987 (CMNH).
 Distribution. Cuba, Dominican Republic.
 Host. Unknown.
 Remarks. This is the first record of A. violaceipes being collected from other than the type locality of Cuba. This is a rare species (Alayo 1969), easily identified by the orange-reddish integument with purple iridescence. Although males are unknown, it is possible that A. purpuripes Banks is a junior synonym of A. violaceipes, as first discussed by Alayo (1969). Only males of A. purpuripes are known, and this species, as currently known, is restricted to Cuba. Further studies are needed to associate the sexes of these species. The specimen we studied here differs from Cuban specimens in being not as stout.

description: Recent theoretical considerations have demonstrated that freestanding graphene doped with alkali metals (AC x ) supports strong Dirac and weak acoustic plasmons. Here we show that when AC x is deposited on a metallic surface, the intense Coulomb screening completely washes out these collective modes. However, even small increase of separation between AC x and metallic surface causes recovery of AC x plasmonic properties and especially the enhancement of acoustic plasmons intensities not present in the freestanding case. We further provide the physical background of these intriguing phenomena. The studied systems consist of lithium- and cesium-doped graphene deposited on Ir(111) surface.

description: From the origin and connotation of the under-forest economy, this paper analyzed plight of the development of under-forest economy in Guangdong mountain areas. It discussed benefits of under-forest economy, favorable conditions and development path of under-forest economy in Guangdong mountain areas. Results indicate that developing under-forest economy is an essential path for realizing green growth and coordinated development of Guangdong mountain areas. However, due to terrain, market, management and technology reasons, the under-forest economy is still not fully developed in Guangdong mountain areas. The development path of under-forest economy suitable for Guangdong mountain areas should be based on ecological protection and oriented towards maximizing ecological, economic and social benefits. Guangdong mountain areas have in-born natural and resource advantages, economic pull of development mode and market demand change, and favorable condition of policy encouragement for development of under-forest economy. Finally, it came up with recommendations for development of under-forest economy in Guangdong mountain areas from development mode, industrial distribution and development direction.
On fast-slow consensus networks with a dynamic weight

description: We study dynamic networks under an undirected consensus communication protocol and with one state-dependent weighted edge. We assume that the aforementioned dynamic edge can take values over the whole real numbers, and that its behaviour depends on the nodes it connects and on an extrinsic slow variable. We show that, under mild conditions on the weight, there exists a reduction such that the dynamics of the network are organized by a transcritical singularity. As such, we detail a slow passage through a transcritical singularity for a simple network, and we observe that an exchange between consensus and clustering of the nodes is possible. In contrast to the classical planar fast-slow transcritical singularity, the network structure of the system under consideration induces the presence of a maximal canard. Our main tool of analysis is the blow-up method. Thus, we also focus on tracking the effects of the blow-up transformation on the network's structure. We show that on each blow-up chart one recovers a particular dynamic network related to the original one. We further indicate a numerical issue produced by the slow passage through the transcritical singularity.

description: Unmanned Aerial vehicles (UAV) are a promising technology for smart farming related applications. Aerial monitoring of agriculture farms with UAV enables key decision-making pertaining to crop monitoring. Advancements in deep learning techniques have further enhanced the precision and reliability of aerial imagery based analysis. The capabilities to mount various kinds of sensors (RGB, spectral cameras) on UAV allows remote crop analysis applications such as vegetation classification and segmentation, crop counting, yield monitoring and prediction, crop mapping, weed detection, disease and nutrient deficiency detection and others. A significant amount of studies are found in the literature that explores UAV for smart farming applications. In this paper, a review of studies applying deep learning on UAV imagery for smart farming is presented. Based on the application, we have classified these studies into five major groups including: vegetation identification, classification and segmentation, crop counting and yield predictions, crop mapping, weed detection and crop disease and nutrient deficiency detection. An in depth critical analysis of each study is provided.

description: Sperner's bound on the size of an antichain in the lattice P(S) of subsets of a finite set S has been generalized in three different directions: by Erdos to subsets of P(S) in which chains contain at most r elements; by Meshalkin to certain classes of compositions of S; by Griggs, Stahl, and Trotter through replacing the antichains by certain sets of pairs of disjoint elements of P(S). We unify Erdos's, Meshalkin's, and Griggs-Stahl-Trotter's inequalities with a common generalization. We similarly unify their accompanying LYM inequalities. Our bounds do not in general appear to be the best possible.

description: We propose a new explanation for the origin of angular momentum in galaxies and their dark halos, in which the halos obtain their spin through the cumulative acquisition of angular momentum from satellite accretion. In our model, the build-up of angular momentum is a random walk process associated with the mass assembly history of the halo's major progenitor. We assume no correlation between the angular momenta of accreted objects. Using the extended Press-Schechter approximation, we calculate the growth of mass, angular momentum, and spin parameter $λ$ for many halos. Our random walk model reproduces the key features of the angular momentum of halos found in N-body simulations: a lognormal distribution in $λ$ with an average of $ \approx 0.04$, independent of mass and redshift. The evolution of the spin parameter in individual halos in this model is quite different from the steady increase with time of angular momentum in the tidal torque picture. We find both in N-body simulations and in our random walk model that the value of $λ$ changes significantly with time for a halo's major progenitor. It typically has a sharp increase due to major mergers, and a steady decline during periods of gradual accretion of small satellites. The model predicts that on average the $λ$ of halos which had major mergers after redshift $z=2$ should be substantially larger than the $λ$ of those which did not. Perhaps surprisingly, this suggests that halos that host late-forming elliptical galaxies should rotate faster than halos of spiral galaxies.
