description: Methodology that recently lead us to predict to an amazing accuracy the date (July 11, 2008) of reverse of the oil price up trend is briefly summarized and some further aspects of the related oil price dynamics elaborated. This methodology is based on the concept of discrete scale invariance whose finance-prediction-oriented variant involves such elements as log-periodic self-similarity, the universal preferred scaling factor lambda=2, and allows a phenomenon of the "super-bubble". From this perspective the present (as of August 22, 2008) violent - but still log-periodically decelerating - decrease of the oil prices is associated with the decay of such a "super- bubble" that has started developing about one year ago on top of the longer-term oil price increasing phase (normal bubble) whose ultimate termination is evaluated to occur in around mid 2010.

NOTE
L’holotype porte une mention de la main de Reichenbach, l’isotype provient de l’herbier de Caen que Reichenbach n’a semble-t-il pas visité.
Goodyera scripta a les entrenoeuds du rhizome plutôt courts et robustes, le limbe des feuilles n’est pas tesselé, mais les écailles basales, les gaines et les bractées comportent des dessins nervurés, les feuilles ne sont ni basales, ni étalées, mais plutôt regroupées au sommet de la tige, les sépales latéraux récurvés ou dirigés vers le bas et le labelle est scrotiforme (Tableau 1). Ces caractères s’appliquent à la définition de Goodyera s.s. de Pace (2020).
Par ailleurs, le nouveau Goodyera décrit dans ce travail et qui est morphologiquement proche de G. scripta, présente des sépales latéraux à peine recourbés à l’extrémité. C’est pourquoi, nous préférons maintenir G. scripta dans le genre Goodyera R.Br., en attendant des études complémentaires qui permettront d’assigner aux deux taxons leur place définitive au sein de la sous-tribu Goodyerinae Klotzsch.

Star Clusters, the Milky Way, and the Gaia Revolution
Creators: name: Cantat-Gaudin, Tristan
Publisher: name: Zenodo

description: The census of stellar structures and star clusters in the Milky Way has been vastly improved in the recent years, largely owing to the Gaia mission. On a large scale, our ability to estimate more reliable ages and distances to clusters allows us to refine our understanding of the structure of our Galaxy and the mechanisms that drive its evolution. The study of young aggregates in the Solar neighbourhood and their internal kinematics has given us important insight on the conditions of star formation. Despite its paradigm-changing impact, Gaia leaves us with many open questions which will be tackled in combination with observations from asteroseismology and ground-base spectroscopy.

description: The variance reduction established by importance sampling strongly depends on the choice of the importance sampling distribution. A good choice is often hard to achieve especially for high-dimensional integration problems. Nonparametric estimation of the optimal importance sampling distribution (known as nonparametric importance sampling) is a reasonable alternative to parametric approaches.In this article nonparametric variants of both the self-normalized and the unnormalized importance sampling estimator are proposed and investigated. A common critique on nonparametric importance sampling is the increased computational burden compared to parametric methods. We solve this problem to a large degree by utilizing the linear blend frequency polygon estimator instead of a kernel estimator. Mean square error convergence properties are investigated leading to recommendations for the efficient application of nonparametric importance sampling. Particularly, we show that nonparametric importance sampling asymptotically attains optimal importance sampling variance. The efficiency of nonparametric importance sampling algorithms heavily relies on the computational efficiency of the employed nonparametric estimator. The linear blend frequency polygon outperforms kernel estimators in terms of certain criteria such as efficient sampling and evaluation. Furthermore, it is compatible with the inversion method for sample generation. This allows to combine our algorithms with other variance reduction techniques such as stratified sampling. Empirical evidence for the usefulness of the suggested algorithms is obtained by means of three benchmark integration problems. As an application we estimate the distribution of the queue length of a spam filter queueing system based on real data.

description: Functionalization of nanoparticles or colloids is increasingly being used to develop customizable "atoms". Functionalization by attaching single strands of DNA allows for direct control of the binding between nanoparticles, since hybridization of double strands will only occur if the base sequences of single strands are complementary. Nanoparticles and colloids functionalized by four single strands of DNA can be thought of as designed analogs to tetrahedral network forming atoms and molecules, with a difference that the attached DNA strands allow for control of the length scale of bonding relative to the core size. We explore the behavior of an experimentally realized model for a nanoparticles functionalized by four single strands of DNA (a tetramer), and show that this single-component model exhibits a rich phase diagram with at least three critical points and four thermodynamically distinct amorphous phases. We demonstrate that the additional critical points are part of the Ising universality class, like the ordinary liquid-gas critical point. The dense phases consist of a hierarchy of interpenetrating networks, reminiscent of a woven cloth. Thus bonding specificity of DNA provides an effective route to generate new nano-networked materials with polyamorphic behavior. The concept of network interpenetration helps to explain the generation of multiple liquid phases in single-component systems, suggested to occur in some atomic and molecular network forming fluids, including water and silica.

The behaviour of small moored vessels in surge and sway
Creators: name: Taylor, Paul Steven
Publisher: name: University of British Columbia
Year: 2010

description: The behaviour of small moored vessels in motions of surge and sway when subjected to a regular incident wave train has been examined. Model tests were performed in a partially standing wave system and experimental results compared to those generated by a computer model. Variables in the analysis include wave height, wave length, wave period, position in a partial standing wave, moorage material stiffness, method of moorage, existence of protection fender, and amount of line slackness. Results indicate a frequency dependence with strong opportunity for resonance for soft moorage systems. Vessel response is affected significantly by wave height, wave frequency and degree of reflection. It is recommended that criteria for marina design should include consideration of all three wave characteristics and suggested design values are presented. Also, to minimize the opportunity for resonant amplification, stiff moorage systems should be adopted by using stiff moorage material, short lines and minimal slackness.

Bringing them together by using van der Waals force to form a heterogeneous structure is new and worth to investigate. In this work, density functional theory (DFT) study of SLGO/graphene has been conducted through varying the interlayer distance. Standard procedures of calculating double-layer heterostructures using DFT has been followed, and several interesting phenomena have been unveiled, for example, band opening in conduction bands of the SLGO and graphene and switching effect of the in-plane optical absorption.

description: Rapeseed is the largest source of China’s edible vegetable oil and plays a pivotal role in China's edible oil market. With global warming and frequent occurrence of various extreme climates, traditional hybrid breeding has been unable to meet the production requirements for rape yield and stress resistance. In recent years, the rapid development and maturity of molecular marker technologies have opened up new ways for stress resistance breeding in rape. This article mainly discusses several types of molecular marker technologies commonly used in rapeseed breeding, such as RFLP, SSR, and SNP, the advantages of molecular marker technologies over conventional breeding and other genetic marker technologies, as well as the application of molecular marker technologies in rapeseed disease resistance, drought resistance, cold resistance and lodging resistance breeding, the current problems and development prospects in breeding.

= Aphaniotis ornata (Lidth De Jeude, 1893)
Paratypes: ZMA. RENA.10989-90, Sabah, North Borneo, coll. Mohari 1912
Type locality: North Borneo [North Kalimantan according to Iskandar & Mumpini (2002)]
Remarks: Japalura nasuta de Jong, 1930 was synonymized with Aphaniotis ornata (van Lidth de Jeude, 1893) by Ota & Hikida (2000). De Jong (1930) stated that the type series of Japalura nasuta comprised six specimens (two males and four females) deposited in the Buitenzorg Museum (now Museum Zoologicum Bogoriense) at the time of the original description. Ota & Hikida (2000) reported that a holotype “was not detected in our survey of various museum collections” and examined a paratype that is deposited in Frankfurt (SMF 78702, adult female, formerly in Mus.[eum] [zoologicum] Bog.[oriense]). Interestingly Daan & Hillenius (1966: 131) and van Tuijl (1995: 131) had already stated that there were two paratypes in the ZMA collection and that the holotype and three further paratypes were in the MZB. This was corroborated by Iskandar & Mumpuni (2002) who stated that the holotype (MZB Lace. 175a, male, North Kalimantan, coll. Mohari 1912) and three paratypes (MZB Lace. 175b, sex undetermined, same data as for the holotype) are present in the Museum Zoologicum Bogoriense. With one paratype too many we reexamined the Naturalis specimens in order to corroborate their type status. De Jong (1930) provided measurements for all specimens he had to hand. A comparison shows that ZMA.RENA.10989 and ZMA.RENA.10990 agree well with the data provided for the female paratypes sp. 3 and sp. 4, respectively (see Table 1). We therefore conclude that the Naturalis specimens represent two of the paratypes. We can further report that the paratype from the Senckenberg collection (SMF 78702) is in very good agreement with sp. 5 in de Jong (1930).

description: First-principles particle-in-cell (PIC) simulation is a powerful tool for understanding plasma behavior, but this power often comes at great computational expense. Artificially reducing the ion/electron mass ratio is a time-honored practice to reduce simulation costs. Usually, this is a severe approximation. However, for steady-state collisionless, electrostatic (Vlasov-Poisson) systems, the solution with reduced mass ratio can be scaled to the solution for the real mass ratio, with no approximation. This 'scaled mass' method, which works with already-existing PIC codes, can reduce the computation time for a large class of electrostatic PIC simulations by the square root of the mass ratio. The particle distributions of the resulting steady state must be trivially rescaled to yield the true distributions, but the self-consistent electrostatic field is independent of the mass ratio. This method is equivalent to 'numerical timestepping,' an approach that evolves electron and ion populations with different timesteps. Numerical timestepping can be viewed as a special case of the speed-limited PIC (SLPIC) method, which is not restricted to steady-state phenomena. Although the scaled-mass approach is simplest, numerical timestepping and SLPIC more easily generalize to include other effects, such as collisions. The equivalence of these new approaches is demonstrated by applying them to simulate a cylindrical Langmuir probe in electron-argon plasma, speeding up simulation by two orders of magnitude. Methods such as SLPIC can therefore play an invaluable role in interpreting probe measurements by including geometric effects, collisions, secondary emission, and non-Maxwellian distributions.

Low energy theory of the t-t'-t''-U Hubbard Model at half-filling: interaction strengths in cuprate superconductors and an effective spin-only description of La_2CuO_4

description: Spin-only descriptions of the half-filled one-band Hubbard model are relevant for a wide range of Mott insulators. In addition to the usual Heisenberg exchange, many new types of interactions, including ring exchange, appear in the effective Hamiltonian in the intermediate coupling regime. In order to improve on the quantitative description of magnetic excitations in the insulating antiferromagnetic phase of copper-oxide (cuprate) materials, and to be consistent with band structure calculations and photoemission experiments on these systems, we include second and third neighbor hopping parameters, t' and t'', into the Hubbard Hamiltonian. A unitary transformation method is used to find systematically the effective Hamiltonian and any operator in the spin-only representation. The results include all closed, four hop electronic pathways in the canonical transformation. The method generates many ring exchange terms that play an important role in the comparison with experiments on La2CuO4. Performing a spin wave analysis, we calculate the magnon dispersion as a function of U,t,t' and t''. The four parameters are estimated by fitting the magnon dispersion to the experimental results of Coldea et al. [Phys. Rev. Lett. 86, 5377, {2001}] for La2CuO4. The ring exchange terms are found essential, in particular to determine the relative sign of t' and t'', with the values found in good agreement with independent theoretical and experimental estimates for other members of the cuprate family. The zero temperature sublattice magnetization is calculated using these parameters and also found to be in good agreement with the experimental value estimated by Lee et al. [Phys. Rev. B 60, 3643 (1999)]. We find a value of the interaction strength U~8t consistent with Mott insulating behavior.

description: Specific heat, electrical resistivity, and magnetic susceptibility measurements on a high quality sample of Mg10Ir19B16 provide a self-consistent determination of its superconducting properties. They indicate that Mg10Ir19B16 is a type-II superconductor (Tc=4.45K, k(0)=20), with an electron-phonon coupling constant l_ep=0.66. An analysis of the T-dependent specific heat shows that superconducting properties are dominated by an s-wave gap (D=0.7 meV). Point contact tunneling data provide evidence for multiple superconducting gaps, as expected from strong asymmetric spin-orbit coupling.

description: Group synchronization arises when two or more synchronization patterns coexist in a network formed of oscillators of different types, with the systems in each group synchronizing on the same time-evolution, but systems in different groups synchronizing on distinct time-evolutions. Group synchronization has been observed and characterized when the systems in each group are identical and the couplings between the systems satisfy specific conditions. By relaxing these constraints and allowing them to be satisfied in an approximate rather than exact way, we observe that stable group synchronization may still occur in the presence of small deviations of the parameters of the individual systems and of the couplings from their nominal values. We analyze this case and provide necessary and sufficient conditions for stability through a master stability function approach, {which also allows us to quantify the synchronization error}. We also investigate the stability of group synchronization in the presence of intra group connections and for this case, extend some of the existing results in the literature. Our analysis points out a broader class of matrices describing intra group connections for which the stability problem can be reduced in a low-dimensional form.
An experimental investigation of a precast concrete connection
Creators: name: Saxena, Rajiv Prakash
Publisher: name: University of British Columbia
Year: 2010

description: Tests on discrete connections for precast concrete panel buildings have shown that it is very difficult to design a ductile embedded connection. Typical connections use studs or reinforcing bars embedded in the edge of the panel and connected to the connection in an adjacent panel with a weld plate or ribbed bar. This is welded either to an exposed length of the embedded steel or to an angle or plate which is welded to the embedded steel. Under earthquake loading the crushing of concrete around the embedment usually leads to premature loss of strength and stiffness of the connection before any significant ductility can occur. If the connections of the precast concrete buildings cannot develop adequate ductility either the whole structure must be designed to remain elastic during an earthquake, or the connections must be stronger than other elements in the structure which can develop the necessary ductility. In practice both of these alternatives may be difficult to achieve. An alternative approach is to use a yielding connector between embedments in adjacent precast panels, in place of a rigid weld plate or bar. One way to do this is to use a mild steel tube with a longitudinal slit to permit shear distortion under earthquake loading. This detail will also accommodate relative movement between panels due to shrinkage and temperature changes. Twenty five split pipe connection specimens, made from four different types of pipe, were tested under cyclic shear loading. Results obtained for the strength, stiffness and ductility of these connections are presented and discussed. A simple formula for calculating the shear strength of these connections is proposed.

description: Minimal, open quantum systems that are governed by non-Hermitian Hamiltonians have been realized across multiple platforms in the past two years. Here we investigate the dynamics of open systems with Hermitian or anti-Hermitian Hamiltonians, both of which can be implemented in such platforms. For a single system subject to unitary and thermal dynamics in a periodic manner, we show that the corresponding Floquet Hamiltonian has a rich phase diagram with numerous exceptional-point (EP) degeneracy contours. This protocol can be used to realize a quantum Hatano-Nelson model that is characterized by asymmetric tunneling. For one unitary and one thermal qubit, we show that the concurrence is maximized at the EP that is controlled by the strength of Hermitian coupling between them. Surprisingly, the entropy of each qubit is also maximized at the EP. Our results point to the multifarious phenomenology of systems undergoing unitary and thermal dynamics.

description: We assume that the initial hydrodynamic environment is a Quark Gluon Plasma (QGP) phase where merely u and d quarks are considered when adding a magnetic field. When considering the chiral magnetic effect in relativistic heavy ion collisions, an anomalous current will be formed in the QGP environment. The chiral magnetic current formed by these u and d quarks has an impact on the heavy quarkonium. By using fluid/gravity duality, the metric with anomalous flow is established by using fluid/gravity duality, so as to introduce the magnetic field effect into the corresponding metric. And then we use heavy quarkonium as a probe to study phase transition, and utilize the effective string tension of the heavy quarkonium to study phase transition by AdS/QCD theory. The characteristics of reporting inverse magnetic catalysis for the confinement-deconfinement transition with anomalous flow are in qualitative agreement with lattice QCD findings. The heavy-quarkonium asymptotic entropy distributions with different magnetic field around the confinement-deconfinement transition temperature are given in the paper.

description: Dynamical chiral symmetry breaking in a QCD-like hidden sector is used to generate the Planck mass and the electroweak scale including the heavy right-handed neutrino mass. A real scalar field transmits the energy scale of the hidden sector to the visible sectors, playing besides a role of inflaton in the early Universe while realizing a Higgs-inflation-like model. Our dark matter candidates are hidden pions that raise due to dynamical chiral symmetry breaking. They are produced from the decay of inflaton. Unfortunately, it will be impossible to directly detect them, because they are super heavy ($10^{9\,\sim\,12}$ GeV), and moreover the interaction with the visible sector is extremely suppressed.

description: Quantum spin Hall (QSH) systems hold promises of low-power-consuming spintronic devices, yet their practical applications are extremely impeded by the small energy gaps. Fabricating QSH materials with large gaps, especially under the guidance of design principles, is essential for both scientific research and practical applications. Here, we demonstrate that large on-site atomic spin-orbit coupling can be directly exploited via the intriguing substrate-orbital-filtering effect to generate large-gap QSH systems and experimentally realized on the epitaxially synthesized ultraflat bismuthene on Ag(111). Theoretical calculations reveal that the underlying substrate selectively filters Bi pz orbitals away from the Fermi level, leading pxy orbitals with nonzero magnetic quantum numbers, resulting in large topological gap of ~1 eV at the K point. The corresponding topological edge states are identified through scanning tunneling spectroscopy combined with density functional theory calculations. Our findings provide general strategies to design large-gap QSH systems and further explore their topology-related physics.

description: Recently, Mike and Farmer have constructed a very powerful and realistic behavioral model to mimick the dynamic process of stock price formation based on the empirical regularities of order placement and cancelation in a purely order-driven market, which can successfully reproduce the whole distribution of returns, not only the well-known power-law tails, together with several other important stylized facts. There are three key ingredients in the Mike-Farmer (MF) model: the long memory of order signs characterized by the Hurst index $H_s$, the distribution of relative order prices $x$ in reference to the same best price described by a Student distribution (or Tsallis' $q$-Gaussian), and the dynamics of order cancelation. They showed that different values of the Hurst index $H_s$ and the freedom degree $α_x$ of the Student distribution can always produce power-law tails in the return distribution $f(r)$ with different tail exponent $α_r$. In this paper, we study the origin of the power-law tails of the return distribution $f(r)$ in the MF model, based on extensive simulations with different combinations of the left part $f_L(x)$ for $x<0$ and the right part $f_R(x)$ for $x>0$ of $f(x)$. We find that power-law tails appear only when $f_L(x)$ has a power-law tail, no matter $f_R(x)$ has a power-law tail or not. In addition, we find that the distributions of returns in the MF model at different timescales can be well modeled by the Student distributions, whose tail exponents are close to the well-known cubic law and increase with the timescale.

description: Observations of the shark-directed bottom longline fishery in the Atlantic Ocean and Gulf of Mexico have been conducted since 1994 (Morgan et al. 2009, Mathers et al. 2020 and references therein). The Southeast Gillnet Observer Program, in its continuing efforts to adapt to the fishery, currently covers anchored (sink and stab), strike, or drift gillnet fishing, regardless of target, by vessels that fish year-round from the east coast of Florida to the Gulf of Mexico. Herein, we summarize fishing effort, catch, and bycatch in these fisheries from 2019 to 2023.
Lexical sophistication measures and writing proficiency: The case of Indonesian learners of Japanese

description: The present study tests two measures of lexical sophistication in writingproficiency (moving-average morphological richness and moving-average mean size ofparadigm for testing the lexical diversity) and mean word length for testing writing form(plain, humble, honorification). The findings suggest that the three metrics work reliably.Regarding lexical diversity, moving-average of morphological richness (MAMR) and movingaverage mean size of paradigm (MAMSP) of Indonesian Japanese learners-written texts areclose to native Japanese-written data. Lexical complexity measured by word length byIndonesian Japanese learners is characterised by slightly less richness than native Japanesedata but remains very close. Word length-frequency relationship in the Indonesian-writtendata presents outstanding fitting results to nine models, including the Poisson Model families and Binomial Model families, with 0.9918 as the lowest and 0.9987 as the highestdetermination coefficient R2. It is hoped that this study’s outcome may help develop anautomatic evaluation of the writing proficiency of agglutinative languages with diversewriting forms.

description: We introduce and solvev a special family of integrable interacting vertex models that generalizes the well known six-vertex model. In addition to the usual nearest-neighbor interactions among the vertices, there exist extra hard-core interactions among pair of vertices at larger distances.The associated row-to-row transfer matrices are diagonalized by using the recently introduced matrix product {\it ansatz}. Similarly as the relation of the six-vertex model with the XXZ quantum chain, the row-to-row transfer matrices of these new models are also the generating functions of an infinite set of commuting conserved charges. Among these charges we identify the integrable generalization of the XXZ chain that contains hard-core exclusion interactions among the spins. These quantum chains already appeared in the literature. The present paper explains their integrability.

description: This article presents the results of experimental research conducted as part of a project concerning a didactical tool named “Design/Gender/Design” which is to be used to introduce gender issues into the training of young designers. The article describes the experimental set-up and students’ results. The intention is to stimulate a discussion about how design should integrate a gender perspective in theory and practice. By observing design as a process of exchange of values and meanings, we aim to understand its responsibility in the diffusion of gender stereotypes, how these gender stereotypes are incorporated into design projects and how they act within and through them, as well as through the sensitivities of designers. Students were asked to respond to design questions concerning gender in order to compile categories of signs targeted at her, him and everybody and covering different aspects (e.g. shapes and sizes, colours, patterns and textures, and typographic elements). Being typical of action research, the experiment allowed students to reflect on the use of gender codes in design and it provided data for researchers to verify assumptions regarding those associations which are implicit when gender is a variable in the design process.
Unusual wave-packet spreading and entanglement dynamics in non-Hermitian disordered many-body systems

description: Non-Hermiticity and dephasing, collaborating in an unusual wave packet dynamics, realizes unconventional entanglement evolution in a disordered, interacting and asymmetric (non-reciprocal) quantum medium. Taking the Hatano-Nelson model as a concrete example, we first consider how wave packet spreads in a non-Hermitian disordered system for demonstraing that it is very different from the Hermitian case. Interestingly, a cascade like wave packet spreading as in the Hermitian case is suppressed in the clean limit and at weak disorder, while it revives in the vicinity of the localization-delocalization transition. Based on this observation, we then analyze how the entanglement entropy of the system evolves in the interacting non-Hermitian model, revealing its non-monotonic evolution in time. We clarify the different roles of dephasing in the time evolution of entanglement entropy in Hermitian and non-Hermitian systems, and show that the many-body dynamics is governed by a principle different from the Hermitian case. The size dependence of the results suggests with the increase of disorder, a unusual area-volume-area law crossover of the maximal entanglement entropy. To analyze the effects of disorder on a firm basis, using the Hermitian limit as a benchmark, we employ a quasi-periodic disorder (Aubry-André model) in the analyses.

Gauge fields, quantized fluxes and monopole confinement of the honeycomb lattice

description: Electron hopping models on the honeycomb lattice are studied. The lattice consists of two triangular sublattices, and it is non-Bravais. The dual space has non-trivial topology. The gauge fields of Bloch electrons have the U(1) symmetry and thus represent superconducting states in the dual space. Two quantized Abrikosov fluxes exist at the Dirac points and have fluxes $2pi$ and $-2pi$, respectively. We define the non-Abelian SO(3) gauge theory in the extended 3$d$ dual space and it is shown that a monopole and anti-monoplole solution is stable. The SO(3) gauge group is broken down to U(1) at the 2$d$ boundary.The Abrikosov fluxes are related to quantized Hall conductance by the topological expression. Based on this, monopole confinement and deconfinement are discussed in relation to time reversal symmetry and QHE. The Jahn-Teller effect is briefly discussed.
