Can photo-evaporation trigger planetesimal formation?

description: We propose that UV radiation can stimulate the formation of planetesimals in externally-illuminated protoplanetary disks. We present a numerical model of disk evolution including vertical sedimentation and photo-evaporation by an external O or B star. As solid material grows and settles toward the disk midplane, the outer layers of the disk become dust depleted. When such a disk is exposed to UV radiation, heating drives photo-evaporative mass-loss from its surface, generating a dust-depleted outflow. The dust:gas surface density ratio in the disk interior grows until dust in the disk midplane becomes gravitationally unstable. Thus, UV radiation fields may induce the rapid formation of planetesimals in disks where sedimentation has occurred.

description: Recent incidents such as the Colonial Pipeline ransomware attack and the SolarWinds hack have shown that traditional defense techniques are becoming insufficient to deter adversaries of growing sophistication. Proactive and deceptive defenses are an emerging class of methods to defend against zero-day and advanced attacks. This work develops a new game-theoretic framework called the duplicity game to design deception mechanisms that consist of a generator, an incentive modulator, and a trust manipulator, referred to as the GMM mechanism. We formulate a mathematical programming problem to compute the optimal GMM mechanism, quantify the upper limit of enforceable security policies, and characterize conditions on user's identifiability and manageability for cyber attribution and user management. We develop a separation principle that decouples the design of the modulator from the GMM mechanism and an equivalence principle that turns the joint design of the generator and the manipulator into the single design of the manipulator. A case study of dynamic honeypot configurations is presented to mitigate insider threats. The numerical experiments corroborate the results that the optimal GMM mechanism can elicit desirable actions from both selfish and adversarial insiders and consequently improve the security posture of the insider network. In particular, a proper modulator can reduce the \textcolor{black}{incentive misalignment} between the players and achieve win-win situations for the selfish insider and the defender. Meanwhile, we observe that the defender always benefits from faking the percentage of honeypots when the optimal generator is presented.
Twistor inspired techniques for gauge theory amplitudes
Creators: name: Quigley, Callum
Publisher: name: University of British Columbia
Year: 2009

description: We examine recent developments in perturbative calculations of gauge theory amplitudes. Motivated by a twistor space analysis, Cachazo, Svrcek and Witten (CSW) formulated a new set of rules for computing scattering amplitudes, which have now been dubbed the CSW rules. We examine the origins of these rules, and apply them to supersymmetric and non-supersymmetric gauge theories. We review many of the recent calculations performed using this new prescription at both the tree and one-loop levels.

Implications of inhomogeneous metal mixing for stellar archaeology

description: The first supernovae enrich the previously pristine gas with metals, out of which the next generation of stars form. Based on hydrodynamical simulations, we develop a new stochastic model to predict the metallicity of star-forming gas in the first galaxies. On average, in internally enriched galaxies, the metals are well mixed with the pristine gas. However, in externally enriched galaxies, the metals can not easily penetrate into the dense gas, which yields a significant metallicity difference between the star-forming and average gas inside a halo. To study the consequences of this effect, we apply a semi-analytical model to Milky Way-like dark matter merger trees and follow stellar fossils from high redshift until the present day with a novel realistic metal mixing recipe. We calibrate the model to reproduce the metallicity distribution function (MDF) at low metallicities and find that a primordial IMF with slope of $\mathrm{d}N/\mathrm{d}M \propto M^{-0.5}$ from $2 Msun$ to $180 Msun$ best reproduces the MDF. Our improved model for inhomogeneous mixing can have a large impact for individual minihalos, but does not significantly influence the modelled MDF at [Fe/H]$\gtrsim -4$ or the best-fitting Pop~III IMF.

Configuration of Single Giant Planet Systems Generating `Oumuamua-Like Interstellar Asteroids

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The first discovered interstellar small object, `Oumuamua (1I/2017 U1), presents unique physical properties of extremely elongated geometric shape and dual characteristics of an asteroid and a comet. These properties suggest a possible origin through tidal fragmentation, which posits that `Oumuamua was produced through intensive tidal fragmentation during a close encounter with a star or a white dwarf, resulting in its shape and ejection from its natal system. According to this mechanism, a high initial orbit eccentricity and a small pericentre of the parent body are necessary to produce `Oumuamua-like objects. To verify whether this mechanism can occur in single giant planet systems, we conduct long-term numerical simulations of systems with a low-mass ($0.5M_\odot$) host star and a giant planet in this study. We determine that an eccentric orbit ($e_\mathrm{p}\sim0.2$) and a Jupiter-mass ($M_\mathrm{p}\sim M_\mathrm{J}$) of the planet appears to be optimal to generate sufficient perturbations for the production of `Oumuamua-like objects. When the planetary semi-major axis $a_\mathrm{p}$ increases, the proportion of planetesimals ejected beyond the system $P(\mathrm{ej})$ increases accordingly, while the possibilities of ejected planetesimals undergoing stellar tidal fragmentation $P(\mathrm{tidal}|\mathrm{ej})$ remains relatively constant at $\sim0.6\%$. Focusing on stellar tidal fragmentation alone, the ratio of extremely elongated interstellar objects to all interstellar objects is $P_\mathrm{e}\sim3\%$.

description: Organic food products are excellent candidates for contract production and marketing because they are produced using a distinct process and are in high demand. This report summarizes survey data on contracting in the organic sector, addressing the extent of contracting, the rationale for using contracts, and contract design for select commodities. The central survey data were collected from certified organic handlers (intermediaries)in the United States who marketed and procured organic products in 2004 and 2007. Contracting is widespread in the organic sector, and, in 2007, firms used contracts most frequently to secure organic products essential to their business and to source products in short supply. Large firms were more likely to use contracts for procurement, and these firms contracted for a larger share of their procurement needs. Nearly all contracts required suppliers to provide evidence of organic certification. Firms using contracts rarely assisted suppliers with obtaining organic certification or the transition to organic. Most contracts include provisions regarding quality, and quality verification was an essential component of these contracts. Prices were determined in a variety of ways and, in some cases, depended on delivered quality.

description: The U(5)-O(6) transitional behavior of the Interacting Boson Model in the large N limit is revisited. Some low-lying energy levels, overlaps of the ground state wavefunctions, B(E2) transition rate for the decay of the first excited energy level to the ground state, and the order parameters are calculated for different total numbers of bosons. The results show that critical behaviors of these quantities are greatly enhanced with increasing of the total number of bosons N, especially fractional occupation probability for d bosons in the ground state, the difference between the expectation value of n_d in the first excited 0^+ state and the ground state, and another quantity related to the isomer shift behave similarly in both the O(6)-U(5) large N and U(5)-SU(3) phase transitions.

description: Phishing attacks remain a significant threat in the digital age, yet organizations lack effective methods to tackle phishing attacks without leaking sensitive information. Phish bowl initiatives are a vital part of cybersecurity efforts against these attacks. However, traditional phish bowls require manual anonymization and are often limited to internal use. To overcome these limitations, we introduce AdaPhish, an AI-powered phish bowl platform that automatically anonymizes and analyzes phishing emails using large language models (LLMs) and vector databases. AdaPhish achieves real-time detection and adaptation to new phishing tactics while enabling long-term tracking of phishing trends. Through automated reporting, adaptive analysis, and real-time alerts, AdaPhish presents a scalable, collaborative solution for phishing detection and cybersecurity education.

description: Beef cow-calf production in the United States is widespread, occurring in every State. Nearly 765,000 farms, about 35 percent of the 2.2 million farms in the United States, had a beef cow inventory in 2007. Most of these were small, part-time operations. About a third of farms that raise beef animals had a beef cow inventory of less than 10 cows, more than half had fewer than 20 cows, and nearly 80 percent had fewer than 50 cows. In this study, ERS uses data from USDA’s 2008 Agricultural Resource Management Survey for U.S. beef cow-calf operations to examine the structure, costs, and characteristics of beef cow-calf producers. Many small operations are “rural residence farms” that specialize in beef cow-calf production, but their income from off-farm sources exceeds that from the farm. Most beef cow-calf production occurs on large farms, but cow-calf production is not the primary enterprise on many of these farms. Findings suggest that operators of beef cow-calf farms have a diverse set of goals for the cattle enterprise.

description: Recently it was highlighted that one-dimensional antiferromagnetic spin models with frustrated boundary conditions, i.e. periodic boundary conditions in a ring with an odd number of elements, may show very peculiar behavior. Indeed the presence of frustrated boundary conditions can destroy the local magnetic orders presented by the models when different boundary conditions are taken into account and induce novel phase transitions. Motivated by these results, we analyze the effects of the introduction of frustrated boundary conditions on several models supporting (symmetry protected) topological orders, and compare our results with the ones obtained with different boundary conditions. None of the topological order phases analyzed are altered by this change. This observation leads naturally to the conjecture that topological phases of one-dimensional systems are in general not affected by topological frustration.

Está fundamentado na aplicação da legislação específica e seus pré-requisitos frente às características peculiares da exploração do cultivo do Açaí no Estado do Pará. A produção foi “rankeada” através do Índice de Desempenho Competitivo – IDC, que serviu para classificar os 20 principais municípios produtores, a partir dos quais se realizam as análises. Os resultados indicam a necessidade de uma concertação interinstitucional e criação de mecanismos de gestão na cadeia produtiva, a fim de vencer os desafios impostos. This work, sustained on growth’s dynamic of natural juice’s consumption as a sportive drink associated mith an image of healthy product, suggest questions related to the application of PIF on production of Açaí, considering the enlargement of acceptation of this product on national’s and international’s market. It is purpose in front of unique caractters of Açaí cultivation on Pará State. The production was ranked by the Competitive Performance’s Index, which classified the 20 main municipal district’s productors that are analysed. The results indicate the necessity of an interinstitucional agreement and a creation of management’s mechanisms on production chain, in order to overcome the enforced challenge.

description: We study gravitational quantum corrections in supersymmetric theories with warped extra dimensions. We develop for this a superfield formalism for linearized gauged supergravity. We show that the 1-loop effective Kahler potential is a simple functional of the KK spectrum in the presence of generic localized kinetic terms at the two branes. We also present a simple understanding of our results by showing that the leading matter effects are equivalent to suitable displacements of the branes. We then apply this general result to compute the gravity-mediated universal soft mass $m_0^2$ in models where the visible and the hidden sectors are sequestered at the two branes. We find that the contributions coming from radion mediation and brane-to-brane mediation are both negative in the minimal set-up, but the former can become positive if the gravitational kinetic term localized at the hidden brane has a sizeable coefficient. We then compare the features of the two extreme cases of flat and very warped geometry, and give an outlook on the building of viable models.

description: In this paper we extend previous work on the relation between the complex structure moduli of the underlying Calabi-Yau manifold in five dimensional supergravity with the time evolution of an embedded 3-brane. We numerically solve the fields' equations for such a construction and focus on dust and radiation filled branes; with the possible application of modeling the universe as a brane-world. It is shown that in both cases the time evolution of the moduli causally connects to the expansion of the brane-world. We also find that in most cases considered there is an early short period of rapid accelerative expansion, indicating an inflationary epoch. We report on these results; leaving analysis of the underlying causes for future work.

description: A key characteristic of many active galactic nuclei (AGN) is their variability, but its origin is poorly understood, especially in the radio domain. Williams et al. (2017) reported a ~50 per cent increase in peak flux density of the AGN in the Seyfert galaxy NGC 4151 at 1.5 GHz with the e-MERLIN array. We present new high resolution e-MERLIN observations at 5 GHz and compare these to archival MERLIN observations to investigate the reported variability. Our new observations allow us to probe the nuclear region at a factor three times higher-resolution than the previous e-MERLIN study. We separate the core component, C4, into three separate components: C4W, C4E and X. The AGN is thought to reside in component C4W, but this component has remained constant between epochs within uncertainties. However, we find that the Eastern-most component, C4E, has increased in peak flux density from 19.35$\pm$1.10 to 37.09$\pm$1.86 mJy/beam, representing a 8.2 sigma increase on the MERLIN observations. We attribute this peak flux density increase to continued interaction between the jet and the emission line region (ELR), observed for the first time in a low-luminosity AGN such as NGC 4151. We identify discrete resolved components at 5 GHz along the jet axis, which we interpret as areas of jet-ELR interaction.

description: We present new observations in X-ray and optical/ultraviolet of the nucleus of NGC1097, known for the abrupt appearance of broad, double-peaked Balmer lines in its spectrum in 1991. These new observations are used to construct the spectral energy distribution (SED) of the central engine. From the SED we infer that this AGN is radio-loud and has a bolometric luminosity L_Bol ~ 10^42 erg/s, implying a low Eddington ratio of L_Bol/L_Edd ~ 10^{-4}. These results suggest that the central ionizing source is an advection-dominated accretion flow (ADAF) in the form of an ellevated structure which photoionizes an outer thin disk. We fit a simplified ADAF model to the SED and obtain limits on the values of the mass accretion rate Mdot and accretion efficiency η, namely Mdot/Mdot_Edd >= 10^{-3} and η<= 10^{-2}. We identify an energy budget problem: if the central photoionizing source is isotropic, the covering factor of the line-emitting portion of the thin accretion disk is ~ 6, i. e. the central source accounts for only 20% of the energy emitted in the double-peaked Balmer lines.

description: A agricultura familiar desempenha um importante papel socioeconômico na sociedade, proporcionando a permanência do homem no campo, conseqüentemente evitando o êxodo rural, e reduzindo o crescimento dos cinturões da pobreza em torno das cidades a procura de trabalho. O foco central do presente estudo concentra-se em discutir os motivos que levam as pequenas famílias rurais a buscar diferentes maneiras de se organizar, e de que maneira isso ocorre. Para isso utilizou-se de estudo de natureza descritiva e exploratória, através de 12 entrevistas semi-estruturadas com produtores rurais, representantes de cooperativas, agroindústrias familiares e com o presidente da Agroart na 30ª Expointer/Esteio, RS. Os resultados obtidos com a pesquisa levam a conclusão que a maioria dos produtores rurais e das agroindústrias está buscando se unir com intuito de organizar os processos produtivos, padronizar produtos, com qualidade e em maior escala, facilitando o acesso aos mercados e aumentando os poderes de barganha junto aos fornecedores de insumos e compradores do produto final. Observou-se que, para a maioria das pequenas famílias entrevistadas, há motivação para organizar a produção por meio de cooperativas. A análise dos dados foi feita qualitativamente utilizando como embasamento teórico agricultura familiar, agroindústrias e cooperativas. The family agriculture plays an important role in socioeconomic society. This fact provides that some people staying in the field and avoiding the rural exodus and poverty in the city. The objective of this study is the discussion about the reasons of the small rural families to look for different ways of organization, and the different ways that it happens. In this study was used the descriptive and exploratory method, through 12 semi-structured interviews with farmers, representatives of cooperatives, family and agricultural industries that were in the 30th Expointer, event that was in Esteio/RS. The results of this study permitted conclude that the majority of farmers and agricultural industries are uniting with the proposed to improve the production processes, furthermore, standardize products, and have quality products. With the increase of scale market the farmers and agricultural industries can bargain in the inputs purchase and with buyers of the final product. In the majority of interviews was said that they are motivated to organize production through cooperatives. Data analysis was performed using a theoretical qualitatively about family farming, agricultural industries and cooperatives.

description: Facilitating healthy eating among young people, particularly among minorities who are at high risk for gaining excess weight, is at the forefront of current policy discussions and food program reviews. We investigate the effects of social interactions and relative prices on fruit and vegetable consumption by African American youths using rich behavioral data from the Family and Community Health Study and area-specific food prices. We find the presence of endogenous effects between a youth and parent, but not between a youth and friend. Lower relative prices of fruits and vegetables tend to increase intakes. Results suggest that health interventions targeting a family member may be an effective way to increase fruit and vegetable intake by African Americans as a result of "spillover" consumption effects between the youths and parents.

Anomalous suppression of large-scale density fluctuations in classical and quantum spin liquids

description: Classical spin liquids (CSLs) are intriguing states of matter that do not exhibit long-range magnetic order and are characterized by an extensive ground-state degeneracy. Adding quantum fluctuations, which induce dynamics between these different classical ground states, can give rise to quantum spin liquids (QSLs). QSLs are highly entangled quantum phases of matter characterized by fascinating emergent properties, such as fractionalized excitations and topological order. One such exotic quantum liquid is the $\mathbb{Z}_2$ QSL, which can be regarded as a resonating valence bond (RVB) state formed from superpositions of dimer coverings of an underlying lattice. In this work, we unveil a \textit{hidden} large-scale structural property of archetypal CSLs and QSLs known as hyperuniformity, i.e., normalized infinite-wavelength density fluctuations are completely suppressed in these systems. In particular, we first demonstrate that classical ensembles of close-packed dimers and their corresponding quantum RVB states are perfectly hyperuniform in general. Subsequently, we focus on a ruby-lattice spin liquid that was recently realized in a Rydberg-atom quantum simulator, and show that the QSL remains effectively hyperuniform even in the presence of a finite density of spinon and vison excitations, as long as the dimer constraint is still largely preserved. Moreover, we demonstrate that metrics based on the framework of hyperuniformity can be used to distinguish the QSL from other proximate quantum phases. These metrics can help identify potential QSL candidates, which can then be further analyzed using more advanced, computationally-intensive quantum numerics to confirm their status as true QSLs.
On the stability of Bose-Fermi mixtures

description: We consider the stability of a mixture of degenerate Bose and Fermi gases. Even though the bosons effectively repel each other the mixture can still collapse provided the Bose and Fermi gases attract each other strongly enough. For a given number of atoms and the strengths of the interactions between them we find the geometry of a maximally compact trap that supports the stable mixture. We compare a simple analytical estimation for the critical axial frequency of the trap with results based on the numerical solution of hydrodynamic equations for Bose-Fermi mixture.

description: This paper develops and applies a methodology to assess the accuracy of historical loss-cost rating procedures, similar to those used by the U.S. Department of Agriculture’s Risk Management Agency (RMA), versus alternative parametric premium estimation methods. It finds that the accuracy of loss-cost procedures leaves much to be desired, but can be markedly improved through the use of alternative methods and increased farm-level yield sample sizes. Evidence suggests that the high degree of inaccuracy in crop insurance premium estimations through historical loss-cost procedures identified in the paper might be a major factor behind the need for substantial government subsidies to keep the program solvent.

description: Transport, magnetic and thermal properties at high magnetic fields (H) and low temperatures (T) of the heavy fermion compound CeAuSb_2 are reported. At H=0 this layered system exhibits antiferromagnetic order below T_N = 6 K. Applying B along the inter-plane direction, leads to a continuous suppression of T_N and a quantum critical point at H_c ~ 5.4 T. Although it exhibits Fermi liquid behavior within the Neel phase, in the paramagnetic state the fluctuations associated with H_c give rise to unconventional behavior in the resistivity (sub-linear in T) and to a TlnT dependence in the magnetic contribution to the specific heat. For H > H_c and low T the electrical resistivity exhibits an unusual T^3-dependence.

Water permeability of spider dragline silk by solid state NMR
Creators: name: Li, Xiang
Publisher: name: University of British Columbia

description: The remarkable mechanical properties of spider dragline silk can be radically altered by the addition of water. Unconstrained spider silk fibers contract to about half of their original length when immersed in water, a phenomenon named supercontraction. With an eye towards understanding supercontraction and facilitating the study of the permeability of other molecules into silk, we use solid-state NMR to investigate the penetration of deuterium oxide into spider dragline silk. The quadrupolar echo NMR experiments are used to examine the hydrogen-deuterium exchange process in a silk sample that has been soaked in deuterium oxide (D20) and then dried. 1 3C-D Rotational Echo Double Resonance (REDOR) NMR experiments are performed to quantify water permeability of silk's different structural regions. In contrast to the indications from previous studies by X-ray diffraction and NMR, our study reveals that the P-sheet crystalline regions of silk are accessible to water. We also show that the correlation between isotope exchange rate and molecular structure, usually found for proteins in solutions and crystal lattices, also holds true for the insoluble silk proteins; the exchange rate is smaller in the /3-sheet crystalline regions than in the rest of the silk. We further found that in the interphase regions of silk, which connect the /3-sheet with the amorphous regions, water permeation is restricted, a reflection of rigid molecular structure or strong hydrogen-bonding in those regions.
