Sibianor tantulus

description: Sibianor tantulus (Simon, 1868)
M a t e r i a l. 1 Ơ, 1 ♀, Chernyhiv Area, Novgorod-Siverskyi Town, 52°00'27'' N, 33°17'57'' E, on the sloping right bank of the Desna River, pitfall, 5.06.1989 (Evtushenko).
 Salticid species S. tantulus has a Trans-Palearctic temperate range; from France, through C. Europe, the middle Urals and C. Siberia, east to Magadan Area, south to Tuva and C. Mongolia (Logunov, 2000). In N. Osetiya S. tantulus specimens habitats are in steppe and young oak forests and steppe meadows (Logunov, 2000). Our specimens were collected in dry birch forest with meadow grasses. As in case of S. larae, distribution of S. tantulus is very wide but its finds in Palearctic are small in numbers (Logunov, 2000).
 In the fauna of Ukraine S. larae and S. tantulus can be characterized as very rare species, therefore further research is needed for their finding and protection. I support Joost Vogels’ (2012) recommendation for arachnologists to verify their own and/or museum collections for clarification of S. aurocinctus, S. larae and S. tantulus distribution.

description: The legacy of mining activities has typically been land "returned to wildlife", or, in some locales, degraded to such an extent that it is unsuitable for any alternate use. Progress towards sustainability is made when value is added to the local environment in terms of the ecological, social and economic well being of the community. In keeping with the principles of sustainable development, the innovative end land use of flooded open pits and tailings impoundments for aquaculture should be explored as it could make a significant contribution to the social equity, economic vitality and environmental integrity of mining communities. As flooding open pits and tailings after mining is a recommended measure for metal mines to inhibit the generation of acid rock drainage (ARD), practicing aquaculture within those pits and tailings impoundments will be in line with government policies for reclamation. In addition, aquaculture in a controlled closed environment may be more acceptable to critics of fish farming who are concerned about fish escapes and viral transmissions to wild populations. The main objective of this venture is to demonstrate that deactivated open pits and tailing ponds from metal and industrial mineral mines in Canada can be used as commercial, recreational or ornamental fish farms. The benefits derived from mining and aquaculture and some of the logistics associated with this venture have spin-off effects. The main concerns about metal bioaccumulation are discussed, as well as ways to mitigate this issue.

description: It is well known that knots are countable in ordinary knot theory. Recently, knots {\it with intersections} have raised a certain interest, and have been found to have physical applications. We point out that such knots --equivalence classes of loops in $R^3$ under diffeomorphisms-- are not countable; rather, they exhibit a moduli-space structure. We characterize these spaces of moduli and study their dimension. We derive a lower bound (which we conjecture being actually attained) on the dimension of the (non-degenerate components) of the moduli spaces, as a function of the valence of the intersection.

description: This article discusses the evolution of the judicial control over discretionary administrative acts, especially the syndicability of the "merit" of these acts, crossing the different theories that have emerged since the consolidation of the idea of ​​the rule of law. After discussing this judicial control in face of the rule of law, the admission of judicial control on the elements of the act is analyzed, and then, this control from implicit parameters of the law. Subsequently, there is a discussion of the theory of direct linkage to principles and "bound" acts by indeterminate legal concepts. Finally, it is discussed the theory of the legal-functional approach, and then, conclude that there is a tendency to systematize, in order to point out some parameters for the jurisdictional control of administrative discretion. The deductive method is used, through research conducted in legislation, doctrine and jurisprudence of the Superior Courts.
Nonlinear Physics: Integrability, Chaos and Beyond

subject: FOS: Physical sciences

description: Integrability and chaos are two of the main concepts associated with nonlinear physical systems which have revolutionized our understanding of them. Highly stable exponentially localized solitons are often associated with many of the important integrable nonlinear systems while motions which are sensitively dependent on initial conditions are associated with chaotic systems. Besides dramatically raising our perception of many natural phenomena, these concepts are opening up new vistas of applications and unfolding technologies: Optical soliton based information technology, magnetoelectronics, controlling and synchronization of chaos and secure communications, to name a few. These developments have raised further new interesting questions and potentialities. We present a particular view of some of the challenging problems and payoffs ahead in the next few decades by tracing the early historical events, summarizing the revolutionary era of 1950-70 when many important new ideas including solitons and chaos were realized and reviewing the current status. Important open problems both at the basic and applied levels are discussed.

description: A model is presented for the high field phase diagram of (TMTSF)$_2$ClO$_4$, taking into account the anion ordering, which splits the Fermi surface in two bands. For strong enough field, the largest metal-SDW critical temperature corresponds to the N=0 phase, which originates from two intraband nesting processes. At lower temperature, the competition between these processes puts at disadvantage the N=0 phase vs. the N=1 phase, which is due to interband nesting. A first order transition takes then place from the N=0 to N=1 phase. We ascribe to this effect the experimentally observed phase diagrams.

Fully resonant scalars on asymptotically AdS wormholes

description: In this work we show the existence of asymptotically AdS wormhole geometries where the scalar probe has an equispaced, fully resonant spectrum, as that of a scalar on AdS spacetime, and explore its dynamics when non-linearities are included. The spacetime is a solution of Einstein-Gauss-Bonnet theory with a single maximally symmetric vacuum. Introducing a non-minimal coupling between the scalar probe and the Ricci scalar remarkably leads to a fully resonant spectrum for a scalar field fulfilling reflective boundary conditions at both infinities. Applying perturbative methods, which are particularly useful for unveiling the dynamics at time scales of order $\varepsilon^{-2}$ (where $\varepsilon$ characterizes the amplitude of the initial perturbation), we observe both direct and inverse energy cascades between modes. This motivates us to explore the energy returns in the case in which the dynamics is dominated by a single mode. We find numerical and perturbative evidence that near exact returns do exist in this regime. We also provide some comments on the fully backreracting case and provide a proof of the universality of the weakly non-linear dynamics around AdS, in the context of Lovelock theories with generic couplings, up to times of order $\varepsilon^{-2}$.

description: The most dramatic phases of terrestrial planet formation are thought to be oligarchic and chaotic growth, on timescales of up to 100-200 Myr, when violent impacts occur between large planetesimals of sizes up to proto-planets. Such events are marked by the production of large amounts of debris as has been observed in some exceptionally bright and young debris disks (termed extreme debris disks). Here we report five years of Spitzer measurements of such systems around two young solar-type stars: ID8 and P1121. The short-term (weekly to monthly) and long-term (yearly) disk variability is consistent with the aftermaths of large impacts involving large asteroid-size bodies. We demonstrate that an impact-produced clump of optically thick dust, under the influence of the dynamical and viewing geometry effects, can produce short-term modulation in the disk light curves. The long-term disk flux variation is related to the collisional evolution within the impact-produced fragments once released into a circumstellar orbit. The time-variable behavior observed in the P1121 system is consistent with a hypervelocity impact prior to 2012 that produced vapor condensates as the dominant impact product. Two distinct short-term modulations in the ID8 system argue for two violent impacts at different times and locations. Its long-term variation is consistent with the collisional evolution of two different populations of impact-produced debris dominated by either vapor condensates or escaping boulders. The bright, variable emission from the dust produced in large impacts from extreme debris disks provides a unique opportunity to study violent events during the era of terrestrial planet formation.

The Roman roads of the Portslade/Aldrington area in relation to a possible Roman port at Copperas Gap.

description: Sussex Archaeological Collections, 143, 135-149
description: From a re-examination of the possible courses of the London to Brighton Roman road through the South Downs it is concluded that it passed to Copperas Gap, on the Portslade/Aldrington coast. Other proposed Roman roads of the Portslade/Aldrington area are also found to have probably ended there. The existence of a Roman port at Copperas Gap is therefore suggested, and some evidence in support of this is presented, from the pattern of Roman remains about the Gap, and the apparent significance of the locality in Saxon times. The region's Roman roads generally are discussed in the light of the port's supposed existence. The question of whether the area might be important for the Saxon conquest of Sussex is raised. Copperas Gap was also found to be the probable site of the recent lost maritime centre of West Aldrington, and a brief account of this is given, including the observation that it could be the place from which Charles II sailed in his escape to France in 1651.

description: There has been increasing interest in emerging implantable medical devices (IMDs) for continuous in vivo sensing of physiological signals, including temperature, PH, pressure, oxygen, and glucose, directly at the target locations. Many of these applications can benefit from wireless, miniaturized IMDs that eliminate the percutaneous power cords and facilitate the implantation procedures. This thesis describes such a device for real-time in vivo monitoring of physiological temperature, such as the monitoring of core body temperature and temperature evaluation during thermal-related therapeutic procedures. Featuring a custom temperature sensor chip with a micron-scale piezoelectric transducer fabricated on top of the chip, the monolithic device, in the form of a mote, measures only 380 μm × 300 μm × 570 μm and weighs only 0.3 mg. The device utilizes ultrasound for wireless powering and communication through the on-chip transducer and achieves aggressive miniaturization through “chip-as-system” integration. The proposed motes were successfully validated in both in vitro experiments with animal tissues and in vivo settings with a mouse model. Compared to the state-of-the-art and equivalent commercial devices, the motes performed comparably or better in a fully-wireless manner while presenting a more compact form factor. Such extreme miniaturization through monolithic integration enables multiple of these motes to be implanted/injected using minimally invasive surgeries with improved biocompatibility and reduced subject discomfort. This offers new approaches for localized in vivo monitoring of spatially-fine-grained temperature distributions and also provides a platform for sensing other types of physiological parameters.

description: "Der amerikanische Elektronikkonzern Apple Inc. will den Markt für Lehrbücher an Schulen aufmischen". Meldungen wie diese bestimmen die aktuelle Diskussion um iPad, iBooks und Co. Dabei wird vernachlässigt, dass eine alleinige Übertragung der Schulbuchinhalte in digitale Form noch nicht zur Revolution des Schulunterrichts beiträgt. Auch wird die Hoffnung vieler Fachdidaktiker und Pädagogen, einen interaktiveren und aktuelleren Unterricht durchführen zu können, bisher durch die existierenden Apps (für den Bildungsbereich existieren bislang über 15.000 iPad-Apps, allerdings für den Bereich der Ökonomischen Bildung bisher nur Quiz-Apps oder aber E-Books) nicht bzw. nur eingeschränkt eingelöst. Apple erhofft sich durch den Einzug von iPads in den Schulunterricht die Erschließung eines neuen, großen Marktsegmentes, aber inwieweit aus fachdidaktischer Perspektive eine Verbesserung von Unterricht mit dem Einsatz solcher Endgeräte erreicht werden kann, ist bisher ungeklärt. Der nachfolgende Beitrag diskutiert am Beispiel der Domäne Wirtschaftswissenschaften und dem Inhaltsfeld "Marktwirtschaft" eine exemplarische Umsetzung schulischer Inhalte in einem interaktiven Schulbuch. Deshalb wird in einem ersten Schritt das Inhaltsfeld kurz umschrieben. In Kapitel 2 werden die auftretenden Vermittlungsprobleme, exemplarisch an der Umsetzung in Schulbüchern diskutiert, um dann Lösungsansätze zu präsentieren. In Kapitel 3 wird das Projekt beschrieben und u.a. auch die verschiedenen technischen Lösungsmöglichkeiten diskutiert, bevor in Kapitel 4 die Umsetzung, exemplarisch an der App "Pit Market" diskutiert werden soll. Abschließend fast ein Fazit die Ergebnisse der Arbeit zusammen.

description: Nowadays, different development methodologies with different degree of agility are followed when building sophisticated software systems. Even when applying these methods, non-functional requirements (NFRs) are often considered too late in the development process and tension that may arise between users' and developers' needs remains mostly neglected. Furthermore, there is a conceptual lack of guidance and support for efficiently fulfilling NFRs in terms of software architecture in general. This paper aims at introducing the AFFINE framework simultaneously addressing these needs with (1) conceptually considering NFRs early in the development process, (2) explicitly balancing end-users' with developers' needs, and (3) a reference architecture providing support for NFRs.

The Born-Oppenheimer approach to the matter-gravity system is illustrated in a simple minisuperspace model and the corrections to quantum field theory on a semiclassical background exhibited. Within such a context the unitary evolution for matter, in the absence of phenomena such as tunnelling or other instabilities, is verified and compared with the results of other approaches. Lastly the simplifications associated with the use of adiabatic invariants to obtain the solution of the explicitly time dependent evolution equation for matter are evidenced.

description: Metasurfaces based on resonant subwavelength photonic structures enable novel ways of wavefront control and light focusing, underpinning a new generation of flat-optics devices. Recently emerged all-dielectric metasurfaces exhibit high-quality resonances underpinned by the physics of bound states in the continuum that drives many interesting concepts in photonics. Here we suggest a novel approach to explain the physics of bound photonic states embedded into the radiation continuum. We study dielectric metasurfaces composed of planar periodic arrays of Mie-resonant nanoparticles ("meta-atoms") which support both symmetry protected and accidental bound states in the continuum and employ the multipole decomposition approach to reveal the physical mechanism of the formation of such nonradiating states in terms of multipolar modes generated by isolated meta-atoms. Based on the symmetry of the vector spherical harmonics, we identify the conditions for the existence of bound states in the continuum originating from the symmetries of both the lattice and the unit cell. Using this formalism we predict that metasurfaces with strongly suppressed spatial dispersion can support the bound states in the continuum with the wavevectors forming a line in the reciprocal space. Our results provide a new way of designing high-quality resonant photonic systems based on the physics of bound states in the continuum.

description: It is shown that a class of important integrable nonlinear evolution equations in (2+1) dimensions can be associated with the motion of space curves endowed with an extra spatial variable or equivalently, moving surfaces. Geometrical invariants then define topological conserved quantities. Underlying evolution equations are shown to be associated with a triad of linear equations. Our examples include Ishimori equation and Myrzakulov equations which are shown to be geometrically equivalent to Davey-Stewartson and Zakharov -Strachan (2+1) dimensional nonlinear Schrödinger equations respectively.

description: In this study we present a data-driven method called false negative control (FNC) screening to address the challenge of detecting weak signals in underpowered genome-wide association studies (GWASs), where true signals are often obscured by a large amount of noise. Our approach focuses on controlling false negatives and efficiently regulates the proportion of false negatives at a user-specified level in realistic settings with arbitrary covariance dependence between variables. We calibrate overall dependence using a parameter that aligns with the existing phase diagram in high-dimensional sparse inference, allowing us to asymptotically explicate the joint effect of covariance dependence, signal sparsity, and signal intensity on the proposed method. Our new phase diagram shows that FNC screening can efficiently select a set of candidate variables to retain a high proportion of signals, even when the signals are not individually separable from noise. We compare the performance of FNC screening to several existing methods in simulation studies, and the proposed method outperforms the others in adapting to a user-specified false negative control level. Moreover, we apply FNC screening to 145 GWAS datasets, obtained from the UK Biobank, and demonstrate a substantial increase in power to retain true signals for downstream analyses.

description: "There is a most profound and beautiful question associated with the observed coupling constant, e - the amplitude for a real electron to emit or absorb a real photon. It is a simple number that has been experimentally determined to be close to 0.08542455. (My physicist friends won't recognize this number, because they like to remember it as the inverse of its square: about 137.03597 with about an uncertainty of about 2 in the last decimal place. It has been a mystery ever since it was discovered more than fifty years ago, and all good theoretical physicists put this number up on their wall and worry about it.) Immediately you would like to know where this number for a coupling comes from: is it related to pi or perhaps to the base of natural logarithms? Nobody knows. It's one of the greatest damn mysteries of physics: a magic number that comes to us with no understanding by man. You might say the "hand of G-d" wrote that number, and "we don't know how He pushed his pencil." We know what kind of a dance to do experimentally to measure this number very accurately, but we don't know what kind of dance to do on the computer to make this number come out, without putting it in secretly!" Not to be put too fine a point on it, I know exactly what kind of dance to do on the computer to makes this number come out, without putting it in secretly...

description: It is well known that there is a bijective correspondence between metric ribbon graphs and compact Riemann surfaces with meromorphic Strebel differentials. In this article, it is proved that Grothendieck's correspondence between dessins d'enfants and Belyi morphisms is a special case of this correspondence. For a metric ribbon graph with edge length 1, an algebraic curve over $\bar Q$ and a Strebel differential on it is constructed. It is also shown that the critical trajectories of the measured foliation that is determined by the Strebel differential recover the original metric ribbon graph. Conversely, for every Belyi morphism, a unique Strebel differential is constructed such that the critical leaves of the measured foliation it determines form a metric ribbon graph of edge length 1, which coincides with the corresponding dessin d'enfant.

description: We have observed localized spin-wave modes in individual thin-film ferromagnetic wires using time-resolved Kerr microscopy as a micron-scale spectroscopic probe. The localization is due to the partial demagnetization of a wire when an external field is applied in the plane of the film and perpendicular to the long axis of the wire. Spatially-resolved spectra demonstrate the existence of distinct modes at the edges of a rectangular wire. Spectral images clearly show the crossover of the two edge modes into a single mode in low applied fields, in agreement with the results of micromagnetic simulations.

description: In the consistent histories formulation of quantum theory, the probabilistic predictions and retrodictions made from observed data depend on the choice of a consistent set. We show that this freedom allows the formalism to retrodict contrary propositions which correspond to orthogonal commuting projections and which each have probability one. We also show that the formalism makes contrary probability one predictions when applied to Gell-Mann and Hartle's generalised time-neutral quantum mechanics.

description: This thesis describes the development and application of microscopically-defined theories of excitons in a wide range of semiconducting materials. In Part I, I consider the topic of singlet exciton fission, an organic photophysical process which generates two spin-triplet excitons from one photoexcited spin-singlet exciton. I construct a theoretical framework that couples a realistic treatment of the static electronic structure with finite-temperature quantum relaxation techniques. This framework is applied separately, but consistently, to the problems of singlet fission in pentacene dimers, crystalline pentacene, and crystalline hexacene. Through this program, I am able to rationalize observed behaviors and make non-trivial predictions, some of which have been confirmed by experiment. In Part II, I present theoretical developments on the properties of neutral excitons and charged excitons (trions) in atomically thin transition metal dichalcogenides. This work includes an examination of material trends in exciton binding energies via an effective mass approach. I also present an experimental and theoretical collaboration, which links the unconventional disposition of excitons in the Rydberg series to the peculiar screening properties of atomically thin materials. The light-matter coupling in these materials is examined within low-energy models and is shown to give rise to bright and dark exciton states, which can be qualitatively labeled in analogy with the hydrogen series. In Part III, I explore theories of relaxation dynamics in condensed phase environments, with a focus on methodology development. This work is aimed towards biological processes, including resonant energy transfer in chromophore complexes and electron transfer in donor-bridge-acceptor systems. Specifically, I present a collaborative development of a numerically efficient but highly accurate hybrid approach to reduced dynamics, which exploits a partitioning of environmental degrees of freedom into those that evolve "fast" and "slow," as compared to the internal system dynamics. This method is tested and applied to the spin-boson model, a two-site Frenkel exciton model, and the seven-site Fenna-Matthews-Olson complex. I conclude with a collaborative analysis of a recently developed polaron-transformed quantum master equation, which is shown to accurately interpolate between the well-known Redfield and Forster theories, even in challenging donor-bridge-acceptor arrangements.
Supplementary Information from Cooperation beyond consanguinity: post-marital residence, delineations of kin and social support among South Indian Tamils

description: Evolutionary ecologists have shown that relatives are important providers of support across many species. Among humans, cultural reckonings of kinship are more than just relatedness, as they interact with systems of descent, inheritance, marriage and residence. These cultural aspects of kinship may be particularly important when a person is determining which kin, if any, to call upon for help. Here, we explore the relationship between kinship and cooperation by drawing upon social support network data from two villages in South India. While these Tamil villages have a nominally male-biased kinship system (being patrilocal and patrilineal), matrilateral kin play essential social roles and many women reside in their natal villages, letting us tease apart the relative importance of genetic relatedness, kinship and residence in accessing social support. We find that people often name both their consanguineal and affinal kin as providing them with support, and we see some weakening of support with lesser relatedness. Matrilateral and patrilateral relatives are roughly equally likely to be named, and the greatest distinction instead is in their availability, which is highly contingent on post-marital residence patterns. People residing in their natal village have many more consanguineal relatives present than those who have relocated. Still, relocation has only a small effect on an individual’s network size, as non-natal residents are more reliant on the few kin that they have present, most of whom are affines. In sum, marriage patterns have an important impact on kin availability, but the flexibility offered by the broadening of the concept of kin helps people develop the cooperative relationships that they rely upon, even in the absence of genetic relatives.This article is part of the theme issue ‘The evolution of female-biased kinship in humans and other mammals’.

description: A map is presented that associates with each element of a loop group a solution of an equation related by a simple change of coordinates to the Camassa-Holm (CH) Equation. Certain simple automorphisms of the loop group give rise to Backlund transformations of the equation. These are used to find 2-soliton solutions of the CH equation, as well as some novel singular solutions.

description: Wave maps (i.e. nonlinear sigma models) with torsion are considered in 2+1 dimensions. Global existence of smooth solutions to the Cauchy problem is proven for certain reductions under a translation group action: invariant wave maps into general targets, and equivariant wave maps into Lie group targets. In the case of Lie group targets (i.e. chiral models), a geometrical characterization of invariant and equivariant wave maps is given in terms of a formulation using frames.

description: The scattering phase, defined as log detSλ/2π i where Sλ is the (unitary) scattering
matrix, is the analogue of the counting function for eigenvalues when dealing with exterior
domains and is closely related to Krein's spectral shift function. We revisit classical results on asymptotics
of the scattering phase and point out that it is never monotone in the case of strong trapping
of waves. Perhaps more importantly, we provide the first numerical calculations of scattering phases
for nonradial scatterers. They show that the asymptotic Weyl law is accurate even at low frequencies
and reveal effects of trapping such as lack of monotonicity. This is achieved by using the recent high
level multiphysics finite element software FreeFEM.

description: Western constitutionalism is characterized by the presence of three main paradigms. The oldest, known as the Liberal State, arising from the constitutional documents of the eighteenth century in the United States and France, was preceded by the pioneering British constitutionalism, of customary, case law, parliamentary origins, since the seventeenth century. In Brazil, it influenced the Constitution of 1891. The Social State paradigm originated in the constitutional documents of the second decade of the twentieth century, such as the Mexican Constitution of 1917 and the German Constitution of 1919. In Brazil, this paradigm emerged in the Constitution of 1934 as well as in the Constitution of 1946. Finally, the Democratic State paradigm, also called Humanist and Social Constitutionalism, was designed in Western Europe from 1945/46 onwards, shortly after the end of the Second World War. These three paradigms are studied in this text in order to better understand the inherent characteristics of the Democratic State paradigm. This paradigm, incidentally, only reached Brazil through the Constitution of the Republic of 1988. The present study also analyzes the adversities and challenges faced by the new constitutional paradigm over the past decades in the West.

description: Ten cycloart-7-ene triterpenoid glycosides, including three new compounds (1–3), were isolated from the roots of Cimicifuga dahurica. Their structures were elucidated on the basis of extensive spectroscopic analyses, chemical methods and comparison with literatures. In addition, the isolates were evaluated for their inhibitory effects on the production of NO, as well as the expressions of iNOS and COX-2 in LPS-stimulated RAW 264.7 macrophages. The results showed that compounds 3, 5, 6, 7 and 8 can reduce the release of NO in a dose-dependent manner. Mechanistically, Western blot analysis indicated that the NO inhibitory effects relied on down-regulating the expression of iNOS, and partially associated with lowering the expression of COX-2.
