Lisserpeton bairdi

description: Lisserpeton bairdi Estes, 1965
The material collected from the Judith River Formation and referable to Lisserpeton consists of a number of atlas and dorsal vertebrae and a fragmentary exoccipital. The Campanian specimens are indistinguishable from those of the Maestrichtian recovered from the Lance Formation, Wyoming, and the Hell Creek Formation, Montana.
DIsCUSSION: The genera Scapherpeton and Lisserpeton are common in the fauna, although the former is more frequent. The Schapherpeton material from the Judith River Formation is identical to that from the large collections obtained from the Lance and Hell Creek formations of Wyoming and Montana. The presence of Lisserpeton in the Judith River Formation extends its geologic range downward and increases its geographic distribution. To date it has been reported from the Lance Formation of Wyoming; from a number of localities near the Fort Peck Reservoir, eastern Montana; and from the late Paleocene of the same region.

description: The goal of the Financial Independence policy conference held on September 16 and 17, 2024 in Washington, D.C. was to bring together experts from the asset and income fields to share theory, evidence, and best practices. The conference was divided into four sessions. The first two sessions were on Children’s Savings Accounts and Baby Bonds, the asset arm of the conference. The third session focused on the income arm. More specifically, it focused on Unconditional Cash Transfers, the Child Tax Credit, and Child Allowances. The final session focused on why solving poverty requires both asset and income proponents to come together. This policy brief is part of the Unconditional Cash Transfers, the Child Tax Credit, and Child Allowances session.
description: It may be hidden in plain sight, but the tax treatment of direct cash transfers can have a critically important impact on the entire field. While this paper is helpful in some respects, what is critically needed is clear guidanceclear guidance is critically needed. The reality is that the nationwide platform of direct cash transfer programs cannot and will not reach its full potential until the Treasury Department and the Internal Revenue ServiceIRS issue the guidance referenced above—guidance that properly states current law in ways that meet the needs of numerous stakeholders and increases the efficacy and scope of programs that address the real-life needs of the millions of recipients and the communities where they live.

description: The spin-orbit coupling may generate spin transverse force on moving electron spin, which gives a heuristic picture for the quantum transverse transport of electron. A relation between the spin and anomalous Hall conductance and spin force was established, and applied to several systems. It was predicted that the sign change of anomalous Hall conductance can occur in diluted magnetic semiconductors of narrow band and can be applied to identify intrinsic mechanism experimentally.

description: Bruchidius raddianae (Anton & Delobel 2003), a species of seed beetle spread in Northern Africa, was detected for the first time in Europe in some localities of the Southern Iberian Peninsula in 2007. In Spain this coleopteran lives on the shrubs of the South African acacia tree, Vachellia karroo (Hayne) Banfi & Galasso, currently present in the Southern Iberian Peninsula. From seeds of V. karroo collected in October 2015, in Lampedusa island, Italy, where this plant is widely spread, 45 specimens of this coleopteran emerged. This observation represents the first record of B. raddianae in Italy and the second one for Europe.

description: We consider a decentralized learning setting in which data is distributed over nodes in a graph. The goal is to learn a global model on the distributed data without involving any central entity that needs to be trusted. While gossip-based stochastic gradient descent (SGD) can be used to achieve this learning objective, it incurs high communication and computation costs, since it has to wait for all the local models at all the nodes to converge. To speed up the convergence, we propose instead to study random walk based SGD in which a global model is updated based on a random walk on the graph. We propose two algorithms based on two types of random walks that achieve, in a decentralized way, uniform sampling and importance sampling of the data. We provide a non-asymptotic analysis on the rate of convergence, taking into account the constants related to the data and the graph. Our numerical results show that the weighted random walk based algorithm has a better performance for high-variance data. Moreover, we propose a privacy-preserving random walk algorithm that achieves local differential privacy based on a Gamma noise mechanism that we propose. We also give numerical results on the convergence of this algorithm and show that it outperforms additive Laplace-based privacy mechanisms.
A Tutorial on Stream-Based Monitoring

Publisher: name: CISPA
Year: 2024

description: Stream-based runtime monitoring frameworks are safety assurance tools that check the runtime behavior of a system against a formal specification. This tutorial provides a hands-on introduction to RTLola, a real-time monitoring toolkit for cyber-physical systems and networks. RTLola processes, evaluates, and aggregates streams of input data, such as sensor readings, and provides a real-time analysis in the form of comprehensive statistics and logical assessments of the system’s health. RTLola has been applied successfully in monitoring autonomous systems such as unmanned aircraft. The tutorial guides the reader through the development of a stream-based specification for an autonomous drone observing other flying objects in its flight path. Each tutorial section provides an intuitive introduction, highlighting useful language features and specification patterns, and gives a more in-depth explanation of technical details for the advanced reader. Finally, we discuss how runtime monitors generated from RTLola specifications can be integrated into a variety of systems and discuss different monitoring applications.
Finite-size scaling analysis of localization transitions in the disordered two-dimensional Bose-Hubbard model within the fluctuation operator expansion method

description: The disordered Bose-Hubbard model in two dimensions at non-integer filling admits a superfluid to Bose-glass transition at weak disorder. Less understood are the properties of this system at strong disorder and energy densities corresponding to excited states. In this work we study the Bose-glass transition of the ground state and the related finite energy localization transition, the mobility edge of the quasiparticle spectrum, a critical energy separating extended from localized quasiparticle excitations. To study these the fluctuation operator expansion is used. The level spacing statistics of the quasiparticle excitations, the fractal dimension and decay of the corresponding wave functions are consistent with a many-body mobility edge. The finite-size scaling of the lowest gaps yields a correction to the mean-field prediction of the superfluid to Bose-glass transition. In its vicinity we discuss spectral properties of the ground state in terms of the dynamic structure factor and the spectral function which also shows distinct behavior above and below the mobility edge.

description: Meligethes (Odontogethes) inexpectatus sp. n. is described from China, Sichuan Province. The new species is based on a female specimen previously incorrectly referred to as Meligethes scrobescens Chen, Lin, Huang & Yang, 2015, which was recently described from a series of male specimens collected in the same area. Both species belong to the taxonomically difficult species-group related to M. chinensis Kirejtshuk, 1979, including a dozen closely related species distributed throughout Nepal and SW and Central China. The true female of Meligethes scrobescens is also described, based on recently collected material from China (Hubei and Chongqing), including a series of male and female specimens. Diagnostic characters distinguishing the new species from all other known members of the M. chinensis species-group and species-complex are discussed, and their overall range distribution are depicted. Additional data on geographic distribution and larval ecology of some of the closely related species are also reported.

description: Communities of the canopy of temperate forests are still relatively unexplored. Furthermore, very little is known on how vertical stratification for some insect groups is related to biological strategies. In this study, we investigated the community composition of both canopy and understory of the families Ampulicidae, Crabronidae and Sphecidae (Hymenoptera) of the Natural Reserve of “Bosco della Fontana”, a remnant lowland forest in northeastern Italy. Observed patterns in vertical stratification have been related to species foraging habits. Our study reveals that the bulk of the community of Spheciformes of the understory consists of species predating dipterans and spiders, while species associated with the canopy are mainly predators of sap-sucking honeydew producers and epiphyte grazers, like aphids, thrips, and barkflies. Comparing the communities of canopy and understory may lead to a better understanding of species ecology and provides useful information to forest managers.

description: Dynamics of a quantum system can be described by coupled Heisenberg equations. In a generic many-body system these equations form an exponentially large hierarchy that is intractable without approximations. In contrast, in an integrable system a small subset of operators can be closed with respect to commutation with the Hamiltonian. As a result, the Heisenberg equations for these operators can form a smaller closed system amenable to an analytical treatment. We demonstrate that this indeed happens in a class of integrable models where the Hamiltonian is an element of the Onsager algebra. We explicitly solve the system of Heisenberg equations for operators from this algebra. Two specific models are considered as examples: the transverse field Ising model and the superintegrable chiral 3-state Potts model.

description: The islands of Tinos and Syros in the Cyclades Archipelago, Greece, have a hilly terrain, a mild Mediterranean climate and vegetation adapted to drought conditions. Caper (Capparis spinosa L.) is highly adapted to arid environments and grows successfully during the Mediterranean summer. In August 2015, we detected serious infestations on wild caper by Eurydema eckerleini (Pentatomidae), which was formerly considered a species endemic to Crete and the Peloponnese, with an isolated report in Turkey. This is the first record of the presence of E. eckerleini in the Cyclades.

description: Quantum state tomography is a powerful, but resource-intensive, general solution for numerous quantum information processing tasks. This motivates the design of robust tomography procedures that use relevant resources as sparingly as possible. Important cost factors include the number of state copies and measurement settings, as well as classical postprocessing time and memory. In this work, we present and analyze an online tomography algorithm designed to optimize all the aforementioned resources at the cost of a worse dependence on accuracy. The protocol is the first to give provably optimal performance in terms of rank and dimension for state copies, measurement settings and memory. Classical runtime is also reduced substantially and numerical experiments demonstrate a favorable comparison with other state-of-the-art techniques. Further improvements are possible by executing the algorithm on a quantum computer, giving a quantum speedup for quantum state tomography.

description: The resonance production of new chiral spin-1 bosons and their detection through the Drell--Yan process at the CERN LHC is considered. Quantitative evaluations of various differential cross-sections of the chiral bosons production are made within the CalcHEP package. The new neutral chiral bosons can be observed as a Breit--Wigner resonance peak in the invariant dilepton mass distribution, as usual. However, unique new signatures of the chiral bosons exist. First, there is no Jacobian peak in the lepton transverse momentum distribution. Second, the lepton angular distribution in the Collins-Soper frame for the high on-peak invariant masses of the lepton pairs has a peculiar "swallowtail" shape.

description: By routing traffic through a random combination of servers worldwide, the darknet obfuscates the identity of its users, making it an attractive medium for journalists, dissidents, and individuals committing crimes. Since 2008, access to the darknet has been facilitated by the The Onion Router (TOR) browser, bringing the darknet within reach of an increasingly wider audience. Tens of thousands of darknet forums serve the criminal needs of millions of users each day and hundreds of these darknet forums are especially dedicated to the exchange of child sexual abuse materials (CSAM). Practitioners who work with men with sexual offences may therefore face individuals whose sexual offences occurred partly or wholly in the darknet. In the current review article, we summarize both the scientific literature and evidence obtained from CSAM forum “take-downs,” to describe the organization of darknet CSAM forums and the activities of their members. These forums report large and international memberships of individuals who, much like mainstream social media, interact online on a regular basis, creating large, online communities in which like-minded individuals can socialize and barter CSAM with minimal risk of discovery. Not all forum members contribute equally to the community, and especially administrators appear indispensable for the proper functioning of the CSAM forum. Implications for future research and law enforcement are discussed.
Traumatic myiasis in farmed animals caused by Wohlfahrtia magnifica in southern Italy (Diptera: Sarcophagidae)

description: Ten herds of sheep and goats (455 heads) were inspected for the presence of traumatic myiasis between May and September 2013 in the province of Cosenza, Calabria, southern Italy. Nine cases were discovered in sheep, goats and a sheepdog. Infested body sites included external genitalia, wounds (sheep and sheepdog) and hooves (goats). Larvae were removed from the infested body areas and reared to adult stage in the laboratory. Both the larvae and the adults were identified as belonging to the Mediterranean screwworm fly Wohlfahrtia magnifica (Schiner, 1862) (Diptera: Sarcophagidae), an obligatory parasite of humans and warm-blooded vertebrates. To our knowledge, these are the first cases of wohlfahrtiosis in sheep and goats to be reported from Calabria. The infested animals were living outdoors in spring and summer, and enclosed in sheds during the autumn and winter months. Observed effects of the myiases included severely impeded walking and tissue damage. Wohlfahrtiosis can cause significant economic loss to farmers. Data about the local distribution, seasonality and types of infestation caused by W. magnifica are useful to farmers and vets to improve control systems, in Calabria as elsewhere within the distributional range of the species

description: For linear Hamiltonian $2n\times 2n$ systems $J y'(x) = (λW(x)+H(x))y(x)$ we investigate the problem how the eigenvalues $λ$ depend on the entries of the coefficient matrix $H$. This question turns into a deformation equation for $H$ and a partial differential equation for the eigenvalues $λ$. We apply our results to various examples, including generalizations of the confluent Heun equation and the Chandrasekhar-Page angular equation. We are mainly concerned with the $2\times 2$ case, and in order to reduce the degrees of freedom in $H$ as much as possible, we will first convert such systems into a complementary triangular form, which is a canonical form with a minimum number of free parameters. Furthermore, we discuss relations to monodromy preserving deformations and to matrix Lax pairs.

Phylogeography and sister group of Lupangus, a new genus for three new flightless allopatric forest litter weevils endemic to the Eastern Arc Mountains, Tanzania (Coleoptera: Curculionidae, Molytinae)
Creators: name: Grebennikov, Vasily V.
Publisher: name: Fragmenta Entomologica

description: This paper reports discovery of a new genus Lupangus gen. n. with three new flightless weevils endemic to the forests of the Eastern Arc Mountains in Tanzania: L. asterius sp. n. (East Usambara; the type species), L. jason sp. n. (Uluguru) and L. orpheus sp. n. (Udzungwa). Maximum Likelihood phylogenetic analyses using parts of mitochondrial (COI), nuclear ribosomal (28S) genes, as well as the nuclear spacer region (ITS2) from 46 terminals grouped together the reciprocally monophyletic Lupangus (3 terminals) and Typoderus (3 terminals), with all three clades strongly supported. Phylogenetic analysis of 32 COI-5’ sequences recovered Lupangus species as reciprocally monophyletic, with L. orpheus being the sister to the rest. Internal phylogeny within both L. jason and L. orpheus are geographically structured, while that of L. asterius is not. Temporal analysis of Lupangus evolution using COI-5’ data assessed under slow and fast substitution rate schemes estimated separation of mitochondrial lineages leading to three Lupangus species at about 7–8 Ma and about 1.9–2.1 Ma, respectively. Temporal analyses consistently failed to suggest correlation between the timing of Lupangus evolution and the late Pleistocene climatic fluctuations, thus rejecting the hypothesis of faunal interchanges during the wettest periods of the last million years. Applicability of flightless weevils for dispersal-vicariance analysis is reviewed, and their mostly undocumented and taxonomically entangled diversity in the Tanzanian Eastern Arc Mountains is briefly highlighted.

Dancing in the "eye of the world" : voyeurism, performance, and the public text in Jane Austen’s scenes of dance
Creators: name: Bjarnason, Palma
Publisher: name: University of British Columbia
Year: 2009

description: Life in Jane Austen's fictional world is carried on under the constant public scrutiny of the "eye of the world." The consciousness of being watched reaches its most intense for Austen's heroines during social dances, one of the only societally sanctioned opportunities for the sexes to intermingle openly. Austen is thereby enabled to use the dance scenario for an investigation of female response to a "surveillance society." In exploring aspects of the dancing-watching relationship (voyeurism; performance; public text), I have grouped the novels into three pairs, according to the aspect which seems to predominate. In Chapter I, I look at voyeuristic acts of observing dance in Sense and Sensibility and Persuasion. Marianne Dashwood, an avid dancer, represents the passive watched object; the other, "active" alternative for women is to watch -- both Elinor Dashwood and Anne Elliot relinquish dance, and thereby preserve themselves from the threats of the performative space. In Chapter II, I focus on performance in Northanger Abbey and Emma: for both Catherine Norland and Emma Woodhouse, awareness of audience becomes a requisite feature of relation to a spectator society, as Austen illustrates the responses of the innocent and the experienced female, respectively, to a performative environment. In Chapter III, I look at Pride and Prejudice and Mansfield Park, where a close examination of Austen's construction of the dance scenes reveals clearly that she emphasises the powerlessness of watched females within the ballroom, and by extension within society. Austen uses the ballroom as a microcosm of a voyeuristic and performative society: the actions of her heroines during scenes of dance are therefore illustrative of the various ways in which a female may negotiate dancing -- and living -- in the eye of the world.

Solving Bethe ansatz equations numerically, we calculate the dependence of the ground state energy on the total magnetic flux through the ring, and the resulting persistent current. Motivated by recent development of quantum entanglement theory, we study the properties of the ground state concurrence under the influence of the flux through the anisotropic Heisenberg ring. We also include an external magnetic field and discuss the properties of the persistent current and the concurrence in the presence of the magnetic field.

GATE: How to Keep Out Intrusive Neighbors
Creators: name: Mustafa, Nimrah

Publisher: name: CISPA
Year: 2024

description: Graph Attention Networks (GATs) are designed to provide flexible neighborhood aggregation that assigns weights to neighbors according to their importance. In practice, however, GATs are often unable to switch off task-irrelevant neighborhood aggregation, as we show experimentally and analytically. To address this challenge, we propose GATE, a GAT extension that holds three major advantages: i) It alleviates over-smoothing by addressing its root cause of unnecessary neighborhood aggregation. ii) Similarly to perceptrons, it benefits from higher depth as it can still utilize additional layers for (non-)linear feature transformations in case of (nearly) switched-off neighborhood aggregation. iii) By down-weighting connections to unrelated neighbors, it often outperforms GATs on real-world heterophilic datasets. To further validate our claims, we construct a synthetic test bed to analyze a model’s ability to utilize the appropriate amount of neighborhood aggregation, which could be of independent interest.

description: Growing demand for corn due to the expansion of ethanol has increased concerns that environmentally sensitive lands retired from agricultural production into the Conservation Reserve Program (CRP) will be cropped again. Iowa produces more ethanol than any other state in the United States, and it also produces the most corn. Thus, an examination of the impacts of higher crop prices on CRP land in Iowa can give insight into what we might expect nationally in the years ahead if crop prices remain high. We construct CRP land supply curves for various corn prices and then estimate the environmental impacts of cropping CRP land through the Environmental Policy Integrated Climate (EPIC) model. EPIC provides edge-of-field estimates of soil erosion, nutrient loss, and carbon sequestration. We find that incremental impacts increase dramatically as higher corn prices bring into production more and more environmentally fragile land. Maintaining current levels of environmental quality will require substantially higher spending levels. Even allowing for the cost savings that would accrue as CRP land leaves the program, a change in targeting strategies will likely be required to ensure that the most sensitive land does not leave the program.

A Primer on US Sugar in the 2007 US Farm Bill

description: This background paper is devoted to US sugar policy. A first section describes the features and economics of the US sugar program; a second section is devoted to the welfare and trade effects of the US sugar program; and a final section reports on potential emerging reforms, their expected effects, and implications. Beyond well-established findings on the social cost and inefficiency of the US sugar program, the main findings of this paper are as follows. The current sugar program is becoming unsustainable because sugar imports are progressively creeping into the US market through regional trade agreements, eventually inducing large sugar inventories, or contracting domestic production to unpalatable low levels in order to maintain high internal prices. The sugar program in its current form is also a potential target for reform because of likely reductions in amber box limits under a potential Doha Agreement of the World Trade Organization (WTO). The current support accounting for sugar under the WTO favors abandoning the current program. A possible outcome would be to change the current sugar program into a standard program, removing the domestic supply controls (allotments), lowering the loan rate, implementing countercyclical, and direct payments, but keeping the current trade protection nearly intact thanks to the high bound-tariff on sugar. Slightly lower consumer prices would result. Payment limitations would penalize large growers. The paper also looks at the cost and implications of a buy-out. The recent resolution of the sweetener dispute (sugar, and corn syrup) between the US and Mexico removes much uncertainty from these markets. Long-term expansion of Mexican sugar exports into the US remains a possibility in 2008. A standard crop program with a lower loan rate would reduce incentives for Mexican producers to export sugar to the US market.

description: Baby Bonds have the potential to play a key role in reducing the racial wealth gap and creating a more equitable future for New Jersey. The racial wealth gap was created by generations of discriminatory policies and practices, and closing it will require a range of policy solutions working together. The establishment of a Baby Bonds program in New Jersey is a critical move toward achieving equity for future generations in one of the most unequal states. Investing in Baby Bonds will empower young people across the state to reach their full potential while addressing wealth disparities. It is time for New Jersey to both design and invest in a new system that connects the next generation of Black and other people of color to its vast prosperity. New Jersey owes it to future generations to be as intentional in connecting them to wealth as it was about separating them from it at its founding.

description: The welfare implications of intellectual property protection (IPP) for private sector agricultural research are analyzed, focusing on the realistic cases in which countries provide different IPP levels, technology spills over across countries, and the public sector is involved in research. A model is developed to determine who benefits from, and who should pay for, the associated research. The paper contains some interesting results on the implications of a harmonization of IPP policies through multilateral agreements or via technology that allows research firms to prevent the copying of plants and animals that express traits that have emerged from their research.

description: The two-dimensional Active Brownian Particles system is meant to be composed of hard disks, that show excluded volume interactions, usually simulated via molecular dynamics using pure repulsive potentials. We show that the softness of the chosen potential plays a role in the result of the simulation, focusing on the case of the emergence of Motility Induced Phase Separation. In a pure hard-sphere system with no traslational diffusion,the phase diagram should be completely determined by their density and Péclet number. However, we have found two additional effects that affect the phase diagram in the ABP model we simulate: the relative strength of the traslational diffusion compared to the propulsion term and the overlapping of the particles. As we show, the second effect can be strongly mitigated if we use, instead of the standard Weeks-Chandler- Andersen potential, a harder one, the pseudo-hard spheres potential. Moreover, in determining the boundary of our phase space, we have tried different approaches to detect MIPS and concluded that observing dynamical features, via the non-Gaussian parameter, is more efficient than observing structural ones, via the local density distribution function. We also demonstrate that the Vogel-Fulcher equation successfully reproduces the decay of the diffusion as a function of density, except for very high density cases. Thus, the ABP system behaves similarly to a fragile glass in this regard.
Long Type I X-ray Bursts and Neutron Star Interior Physics

description: Superbursts are very energetic Type I X-ray bursts discovered in recent years by long term monitoring of X-ray bursters, believed to be due to unstable ignition of carbon in the deep ocean of the neutron star. A number of "intermediate duration" bursts have also been observed, probably associated with ignition of a thick helium layer. We investigate the sensitivity of these long X-ray bursts to the thermal profile of the neutron star crust and core. We first compare cooling models of superburst lightcurves with observations, and derive constraints on the ignition mass and energy release, and then calculate ignition models for superbursts and pure helium bursts, and compare to observations. The superburst lightcurves and ignition models imply that the carbon mass fraction is approximately 20% or greater in the fuel layer, constraining models of carbon production. However, the most important result is that when Cooper pairing neutrino emission is included in the crust, the temperature is too low to support unstable carbon ignition at the observed column depths. Some additional heating mechanism is required in the accumulating fuel layer to explain the observed properties of superbursts. If Cooper pair emission is less efficient than currently thought, the observed ignition depths for superbursts imply that the crust is a poor conductor, and the core neutrino emission is not more efficient than modified URCA. The observed properties of helium bursts support these conclusions, requiring inefficient crust conductivity and core neutrino emission.

Year: 2017

description: Here we present a synthesis on the current knowledge of sphodrine carabids of the southern Levant (Israel, areas under Palestinian control, Lebanon, Jordan, Egypt east of Suez Channel: Sinai). A key for the identification of genera, subgenera and species is provided. Two new species are described: Taphoxenus (Lychnifugus) ziegleri sp. n. is described from Jordan (Type locality: Madaba), close to T. (L.) meridionalis Casale, 1988 (valid species), but markedly distinct for several characters both in external features and male genitalia. Laemostenus (Laemostenus) sinaiticus sp. n. is described from southern Sinai (Type locality: St. Catharina Monastery). This species belongs to the L. quadricollis species group (in the sense of Casale, 1988), and is close to L. aegyptiacus Schatzmayr, 1936. An updated key for the identification of the species of this group known so far in that area, which includes both epigean and subterranean species, is provided. The diagnostic features of all species newly described are illustrated, and their possible relationships are discussed. Furthermore, the features of male genitalia of Laemostenus (Laemostenus) aegyptiacus Schatzmayr, 1936 and Laemostenus (Laemostenus) libanensis (Piochard de la Brûlerie, 1876) are illustrated for the first time. The latter, known so far from the remains of the holotype specimen, is redescribed from material recently sampled in Lebanon.

Four new species, DNA barcode library and pre-Pliocene speciation of the euedaphic Afromontane Clivinini genera Trilophidius and Antireicheia (Coleoptera: Carabidae, Scaritinae)

description: We describe and extensively illustrate four new species of euedaphic (= dwelling in the soil) Clivinini ground beetles: Trilophidius acastus sp. nov. and T. argus sp. nov. (both from Bioko, Equatorial Guinea), as well as Antireicheia calais sp. nov. and A. zetes sp. nov. (both from the South Pare Mountains, Tanzania). We generate and report all currently available DNA barcode (= cytochrome oxidase subunit I) data for euedaphic Afromontane Clivinini of the genera Trilophidius (2 species, four records) and Antireicheia (13 species, 43 records). We infer a phylogeny for these beetles using a Maximum Likelihood approach based upon a matrix of 53 sequenced specimens (dx.doi.org/10.5883/DS-ANTIREI) with 658 aligned positions. All nominative species represented by two or more sequences are recovered as monophyletic. Both new species of Trilophidius form a weakly supported clade, while all seven species of South African Antireicheia form a moderately supported clade. The genus Antireicheia and the geographical assemblage of its six Tanzanian species are not monophyletic. We perform divergence time estimation in Afrotropical Antireicheia, and our analysis indicates that these lineages diverged predominantly in the middle or late Miocene. We highlight the notable lack of phylogenetic hypothesis linked with the vaguely and variably defined taxon “subfamily Scaritinae” and its subordinated taxa.

description: In the months following the reopening of the Japanese market to imports of U.S. beef on July 26, 2006, Japanese importers were unable to procure adequate supplies. This paper discusses reasons for early supply shortages and some of the policy and trade issues that will affect demand for U.S. beef in the short to medium term. The paper also discusses current marketing efforts for domestic and imported beef, new marketing technologies, and general consumer trends. The information presented in this paper includes on-site observations and data from meetings with Japanese importers and retailers and industry experts during market research in Tokyo and Osaka in November 2006.

description: The non-Markovianity of an arbitrary open quantum system is analyzed in reference to the multi-time statistics given by its monitoring at discrete times. On the one hand, we exploit the hierarchy of inhomogeneous transfer tensors, which provides us with relevant information about the role of correlations between the system and the environment in the dynamics. The connection between the transfer-tensor hierarchy and the CP-divisibility property is then investigated, by showing to what extent quantum Markovianity can be linked to a description of the open-system dynamics by means of the composition of 1-step transfer tensors only. On the other hand, we introduce the set of stochastic transfer tensor transformations associated with local measurements on the open system at different times and conditioned on the measurement outcomes. The use of the transfer-tensor formalism accounts for different kinds of memory effects in the multi-time statistics and allows us to compare them on a similar footing with the memory effects present in non-monitored non-Markovian dynamics, as we illustrate on a spin-boson case study.

description: Three old specimens of Stephanopachys linearis (Kugelann, 1792) from NE Italy, Udine Province (Friuli-Venezia Giulia Region) are recorded. This is the first certain record of this species for Italy since the only previous records, from South Tyrol, were doubtful. This new record is of high conservation value, since this species is protected by the Habitats Directive in the European Union. Distributional and biological data on S. linearis are summarized and it is documented that the previous, doubtful literature records from South Tyrol are erroneous.
