description: Spin transport property of polarization induced two-dimensional electron gas channel formed in the central vertical plane of a wedge-shaped \textit{c}-oriented GaN nanowall is investigated theoretically. Since the confining potential preserves the spatial symmetry between the conduction and valence band, the Rashba effect is suppressed in this system even when the shape of the wedge is asymmetric. It has been found that the relaxation of the electron spin oriented along the direction of the confinement via D'yakonov-Perel' (DP) mechanism, which is the dominant process of relaxation in this high mobility channel, is entirely switched off at low temperatures. Spin relaxation can be turned on by applying a suitable bias at the gate. Exploiting this remarkable effect, a novel all electrically driven spin-transistor has been proposed.

description: We investigate theoretically Fermionic superfluidity induced by Feshbach resonance in the orbital p-wave channel. We show that, due to the dipole interaction, the pairing is extremely anisotropic. When this dipole interaction is relatively strong, the pairing has symmetry $k_z$. When it is relatively weak, it is of symmetry $k_z + i βk_y$ (up to a rotation about $\hat z$, here $β< 1$). A phase transition between these two states can occur under a change in the magnetic field or the density of the gas.

Radiative leptonic decays of heavy mesons in heavy quark limit
Creators: name: Hwang, Chien-Wen
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study the radiative leptonic decays of heavy mesons within the covariant light-front model. Using this model, both the form factors F_V and F_A have the same form when the heavy quark limit is taken. In addition, the relation between the form factor F_V and the decay constant of heavy meson F_H is obtained. The hadronic parameter βcan be determine by the parameters appearing in the wave function of heavy meson. We find that the value of βis not only quite smaller than the one in the non-relativistic case, but also insensitive to the value of light quark mass m_q. These results mean that the relativistic effects are very important in this work. We also obtain the branching ratio of B\to lν_l γis about (1.40-1.67)\times 10^{-6}, in agreement with the general estimates in the literature.

description: This assessment of research and extension in conservation farming in northern NSW was done as part of a systematic process of evaluating the economic, social and environmental impacts of major research, extension and education programs. The conservation farming program was a key area of investment by NSW Agriculture and an evaluation process fulfils accountability and resource allocation requirements. This analysis evaluates the investments by the former NSW Agriculture in conservation farming and reduced tillage programs from the late 1970s to 2002. The benefit-cost ratios (BCR) for no till only and no till plus reduced tillage practices up to 2002 were 4.1:1 and 9:1, respectively. The net present values (NPV) of the benefits from these efforts up to 2002 were $78 and $205 million, respectively. When program activities are extended to 2020 the BCRs were 11.4:1 and 20.5:1 and the NPVs were $302 million and $568 million, respectively. There are likely to be other benefits such as environmental benefits of reduced soil erosion (and reduced infrastructure remediation costs) and improved soil structure. Without the RD&E programs of NSW Agriculture and other agencies the slower growth in productivity is likely to have retarded farm and industry profitability, with associated effects on industry and community strength.

description: We demonstrate high speed manipulation of a few-electron double quantum dot. In the one-electron regime, the double dot forms a charge qubit. Microwaves are used drive transitions between the (1,0) and (0,1) charge states of the double dot. A local quantum point contact charge detector measures the photon-induced change in occupancy of the charge states. Charge detection is used to measure T1~16 ns and also provides a lower bound estimate for T2* of 400 ps for the charge qubit. In the two-electron regime we use pulsed-gate techniques to measure the singlet-triplet relaxation time for nearly-degenerate spin states. These experiments demonstrate that the hyperfine interaction leads to fast spin relaxation at low magnetic fields. Finally, we discuss how two-electron spin states can be used to form a logical spin qubit.

The development of a utopian city? Comparing land- and skyscapes in Santa Cruz de Tenerife and San Cristobal de la Laguna

description: We discuss the peculiar planning of the city of San Cristobal de La Laguna, in the Canary Island of Tenerife (Spain), when compared to the nearby and essentially contemporary Santa Cruz de Tenerife, which served as a maritime port of the former city. For this we review our previous study of the exact spatial orientation of twenty-one historic Christian churches currently existing in the old part of La Laguna, which we compare with the analysis of six similar buildings located in Santa Cruz, and presented here for the first time. In both cities, we take the spatial orientation of historic churches as good indicators of the original layout of the respective urban lattices. Although we find a clear orientation pattern for La Laguna, which singles out an absolute-value astronomical declination slightly below 20 degrees, pointing to a preferred date close to the July 25th feast-day of San Cristobal de Licia, in the case of Santa Cruz this trend is not followed. On the contrary, the pattern we find for Santa Cruz, within the uncertainties due to the low statistics, and apart from one equinoctial and one solstitial oriented churches, is consistent with an orographic orientation within the canonic limits of sunrise. This result highlights the uniqueness of the city of La Laguna, and supports the idea suggesting its deliberate planning in the early 16th century.

description: The residual stress plays a vital role in determination of the device performance that uses thin films coating and thus the accurate determination of stress and its optimization with process parameters is an ongoing research work for many decades. In line with this, the microscopic origin of the stress at the atomic scale and its development during the thin film deposition is a matter of major scientific interests. The development of stress is a complex phenomenon and has a complex dependence to process parameters, film microstructure and its morphology. In this work, by utilizing a custom-designed cathodic arc deposition system and synchrotron radiation based 2D x-ray diffraction (XRD) technique, we determine the real-time evolution of stress, crystallite sizes and their preferential orientations of Aluminum-Titanium-Nitride (AlxTi1-xN) films with varied Al-content (x=0.0, 0.25, 0.50, and 0.67) on Si-100 substrate. The energies of incoming ions and hence stress in the films is tuned by applying different direct current substrate bias (Vs = floating potential, -20, -40, -60, -80, and -100 V). The instantaneous stress is evaluated by the well-known d vs. sin2ψ technique, while crystallite sizes are determined by analyzing line profiles of x-ray diffractograms. The evolution of stress and crystallite sizes are modelled with multiple numerical models from which kinetic parameters associated with the thin film depositions are extracted. The ex-situ microstructure characterizations of AlxTi1-xN coatings are carried out by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The formation of ex-situ microstructure of the films is discussed considering the results obtained from in-situ XRD data. Finally, we demonstrate that the method utilized here is a powerful approach towards estimation of the fracture toughness of thin film coatings.

description: We study the electronic and topological properties of fully relaxed twisted bilayer (TBG) and double bilayer (TDBG) graphene under perpendicular pressure. An approach has been proposed to obtain the equilibrium in-plane structural deformation and out-of-plane corrugation in moiré superlattices under pressure. We find that the in-plane relaxation becomes much stronger under higher pressure, while the corrugation height in each layer is maintained. The comparison between band structures of relaxed and rigid structures demonstrates that not only the gaps on the electron and hole sides ($Δ_e$ and $Δ_h$) are significantly underestimated without relaxation but also the detailed dispersions of the middle bands of rigid structures are rather different from those of relaxed systems. $Δ_e$ and $Δ_h$ in TBG reach maximum values around critical pressures with narrowest middle bands. Topological transitions occur in TDBG under pressure with the middle valence and conduction bands in one valley touching and their Chern numbers transferred to each other. The pressure can also tune the gap at the neutrality point of TDBG, which becomes closed for a pressure range and reopened under higher pressure. The behavior of electronic structure of supertlattices under pressure is sensitive to the twist angle $θ$ with the critical pressures generally increase with $θ$.

description: We present results from a 112 ks long look by XMM-Newton at the ultraluminous X-ray source (ULX) Holmberg II X-1, long thought to be the one of best candidates for the missing class of intermediate mass black holes (IMBHs). Our data comprises the first high quality XMM-Newton/RGS spectrum of an ULX, and an XMM-Newton/EPIC spectrum with unprecedented signal-to-noise. A detailed timing analysis shows that any variability on time-scales of minutes to hours is very weak (< few per cent fractional rms), though larger amplitude variations on much shorter time-scales could be hidden by photon counting statistics. This result suggests that if Ho II X-1 harbours an IMBH, then we are observing this source in a highly unusual and atypical state when compared with the known variability behaviour of other accreting systems of large mass. Moreover unlike Galactic X-ray binaries, our spectral analysis indicates the possible presence of an optically-thick low temperature corona. Taken together our timing and spectral analysis suggests that the compact companion is most-likely a high luminosity analogue of black hole binary systems similar to GRS 1915+105, the Galactic microquasar, harbouring a compact object of mass no greater than 100 solar masses.

description: Context. As recently demonstrated, high-z submillimetre galaxies (SMGs) are the perfect background sample for tracing the mass density profiles of galaxies and clusters (baryonic and dark matter) and their time-evolution through gravitational lensing. Their magnification bias, a weak gravitational lensing effect, is a powerful tool for constraining the free parameters of a halo occupation distribution (HOD) model and potentially also some of the main cosmological parameters. Aims. The aim of this work is to test the capability of the magnification bias produced on high-z SMGs as a cosmological probe. We exploit cross-correlation data to constrain not only astrophysical parameters ($M_{min}$, $M_1$, and $α$), but also some of the cosmological ones ($Ω_m$, $σ_8$, and $H_0$) for this proof of concept. Methods. The measured cross-correlation function between a foreground sample of GAMA galaxies with spectroscopic redshifts in the range 0.2 < z < 0.8 and a background sample of H-ATLAS galaxies with photometric redshifts >1.2 is modelled using the traditional halo model description that depends on HOD and cosmological parameters. These parameters are then estimated by performing a Markov chain Monte Carlo analysis using different sets of priors to test the robustness of the results and to study the performance of this novel observable with the current set of data Results. With our current results, $Ω_m$ and $H_0$ cannot be well constrained. However, we can set a lower limit of >0.24 at 95\% confidence level (CL) on $Ω_m$ and we see a slight trend towards $H_0>70$ values. For our constraints on $σ_8$ we obtain only a tentative peak around 0.75, but an interesting upper limit of $σ_8\lesssim 1$ at 95\% CL. We also study the possibility to derive better constraints by imposing more restrictive priors on the astrophysical parameters.

Discovering outstanding subgroup lists for numeric targets using MDL

description: The task of subgroup discovery (SD) is to find interpretable descriptions of subsets of a dataset that stand out with respect to a target attribute. To address the problem of mining large numbers of redundant subgroups, subgroup set discovery (SSD) has been proposed. State-of-the-art SSD methods have their limitations though, as they typically heavily rely on heuristics and/or user-chosen hyperparameters. We propose a dispersion-aware problem formulation for subgroup set discovery that is based on the minimum description length (MDL) principle and subgroup lists. We argue that the best subgroup list is the one that best summarizes the data given the overall distribution of the target. We restrict our focus to a single numeric target variable and show that our formalization coincides with an existing quality measure when finding a single subgroup, but that-in addition-it allows to trade off subgroup quality with the complexity of the subgroup. We next propose SSD++, a heuristic algorithm for which we empirically demonstrate that it returns outstanding subgroup lists: non-redundant sets of compact subgroups that stand out by having strongly deviating means and small spread.

description: Astronomical observation data require long-term preservation, and the rapid accumulation of observation data makes it necessary to consider the cost of long-term archive storage. In addition to low-speed disk-based online storage, optical disk or tape-based offline storage can be used to save costs. However, for astronomical research that requires historical data (particularly time-domain astronomy), the performance and energy consumption of data-accessing techniques cause problems because the requested data (which are organized according to observation time) may be located across multiple storage devices. In this study, we design and develop a tool referred to as AstroLayout to redistribute the observation data using spatial aggregation. The core algorithm uses graph partitioning to generate an optimized data placement according to the original observation data statistics and the target storage system. For the given observation data, AstroLayout can copy the long-term archive in the target storage system in accordance with this placement. An efficiency evaluation shows that AstroLayout can reduce the number of devices activated when responding to data-access requests in time-domain astronomy research. In addition to improving the performance of data-accessing techniques, AstroLayout can also reduce the storage systems power consumption. For enhanced adaptability, it supports storage systems of any media, including optical disks, tapes, and hard disks.

description: It was realized two decades ago that the two-dimensional diffusive Fermi liquid phase is unstable against arbitrarily weak electron-electron interactions. Recently, using the nonlinear sigma model developed by Finkelstein, several authors have shown that the instability leads to a ferromagnetic state. In this paper, we consider diffusing electrons interacting through a ferromagnetic exchange interaction. Using the Hartree-Fock approximation to directly calculate the electron self energy, we find that the total energy is minimized by a finite ferromagnetic moment for arbitrarily weak interactions in two dimensions and for interaction strengths exceeding a critical proportional to the conductivity in three dimensions. We discuss the relation between our results and previous ones.

description: The recently observed color suppressed B0bar to D0 pi0, D0 eta, D0 eta', Ds+ K-and D0 K0bar decay modes all have rates larger than expected, hinting at the presence of final state interactions. We study rescattering effects in Bbar to D P, D Kbar and Dbar Kbar modes in the quasi-elastic approach, which is extended to accommodate D0 eta' without using U(3) symmetry. The D0bar Kbar modes are of interest in the determination of the unitarity angle phi3/gamma. The updated DP data are used to extract the effective Wilson coefficients a_1^{eff} ~ 0.92, a_2^{eff} ~ 0.22, three strong phases delta ~ 62 deg., theta ~ 24 deg., sigma ~ 127 deg., and the mixing angle tau~2 deg. The values of delta and theta are close to our previous results. The smallness of tau implies small mixing of D0 eta1 with other modes. Predictions for D0 K-, D+ K- and D0 K0bar agree with data. The framework applies to Bbar to Dbar Kbar decays, and rates for D0bar K-, D- K0, Ds- pi0, Ds- eta and Ds- eta' modes are predicted. From B- to D0bar K- and D0 K- rates, we find r_B=0.09\pm 0.02.

description: Quantum key distribution (QKD) can help two distant peers to share secret key bits, whose security is guaranteed by the law of physics. In practice, the secret key rate of a QKD protocol is always lowered with the increasing of channel distance, which severely limits the applications of QKD. Recently, twin-field (TF) QKD has been proposed and intensively studied, since it can beat the rate-distance limit and greatly increase the achievable distance of QKD. Remarkalebly, K. Maeda et. al. proposed a simple finite-key analysis for TF-QKD based on operator dominance condition. Although they showed that their method is sufficient to beat the rate-distance limit, their operator dominance condition is not general, i.e. it can be only applied in three decoy states scenarios, which implies that its key rate cannot be increased by introducing more decoy states, and also cannot reach the asymptotic bound even in case of preparing infinite decoy states and optical pulses. Here, to bridge this gap, we propose an improved finite-key analysis of TF-QKD through devising new operator dominance condition. We show that by adding the number of decoy states, the secret key rate can be furtherly improved and approach the asymptotic bound. Our theory can be directly used in TF-QKD experiment to obtain higher secret key rate. Our results can be directly used in experiments to obtain higher key rates.

description: In this work, we make a theoretical study on the $p \bar p \rightarrow Λ\barΛη$ reaction for antiproton beam energy from threshold to 4GeV within an effective Lagrangian approach and isobar model. By assuming this reaction is dominated by the excitation of $Λ$ and $\bar Λ$ resonances in intermediate states, we calculate the total cross sections and give the predictions of the angular distribution and invariant mass spectrum of final particles. In particular, we discuss the possibility to verify the existence of a narrow $Λ$ resonance found in the process of $K^- p\to ηΛ$ in the present reaction. It shows that the $p \bar p \rightarrow \bar ΛΛη$ reaction can provide us with valuable information about the $Λ$ resonances having significant couplings to $\bar K N$ and $Λη$ channels. Thus the experimental data of this reaction will be a good supplement to the $\bar K N\toηΛ$ scattering data for studying $Λ$ resonances.

Otolithus (Pagelli) elegantulus Koken, 1888: 279.
Material examined
UNITED STATES OF AMERICA – Mississippi • 1 sagitta; Catahoula Formation; MMNS VP-12077.
Description
The outline of MMNS VP-12077 is essentially a square. The margins are primarily irregular with varying indications of lobation, sinuosity, and smoothness. The height/length ratio is about 0.65. The inner face tends to be slightly and fairly evenly convex (Fig. 29B). A prominent heterosulcoid-type sulcus extends across approximately 85% of the inner face (Fig. 29A). The sulcus, which is located slightly dorsal, is essentially horizontal except for a very small, downwardly flexed posterior of the cauda. The ostium opens on the anterior margin. The dorsal and ventral margins of the ostium are approximately parallel. The posteroventral portion of the ostium does not extend underneath the cauda. The ostium is approximately 40% of the length of the cauda. The height of the cauda is approximately 50–60% of the height of the ostium. Approximately 80% of the cauda is horizontal with about 20% downturned. The downturned portion is approximately 45° from horizontal. There is an irregularly shaped, dorsal depression above the cauda and a faint ventral furrow located away from the ventral margin. The outer face is slightly concave and may be slightly irregular.
Remarks
The single specimen was tentatively assigned to Sparus elegantulus due to its preservation. The species was originally identified by Koken (1888) in the Gulf Coast Plain of the USA. Sparus? elegantulus is known from the Eocene of Alabama, Georgia, Louisiana, and Mississippi (Nolf & Stringer 2003; Nolf 2013; Stringer et al. 2022a). Within Oligocene deposits, the species has previously been reported from the Rupelian Glendon Limestone (NP22/23) in Mississippi (Stringer et al. 2020c) and from the Glendon Limestone Member of the Byram Formation (NP23) of Alabama by Ebersole et al. (2021). In the latter occurrence, the species was relatively abundant and represented 12.06% of the total otolith sample.

description: Very little attention has been given to the modeling of yield distribution for crops and regions in which yields exhibit irregular behavior. We undertake a statistical case study of Texas upland cotton and propose an alternative mixture distribution based on regime-switching model in which the conditional distribution of yield depends upon an observable drought index. The results show that the mixture distribution model provides a better fit to the data than conventional parametric distributions and produces higher implied premium rates than the current published Group Risk Plan insurance rates in more than two-thirds of Texas counties examined.

They also provide important clues to study various interesting phenomena such as the gluon shadowing and color glass condensate. We report the latest results from PHENIX experiment on $J/ψ$ production in $p+p$ and $d+Au$ collisions at forward, backward and midrapidity.

description: This essay develops a new method to diagnose inconsistency in dichotomous choice contingent valuation with follow-up questions: in particular, downward bias in the mean WTP. It is shown that the previous methods aimed to explain this inconsistency in responses have ignored statistical inconsistency: non-perfect correlation between the initial and follow-up responses and thus have provided wrong predictions to explain respondents' inconsistency pattern. In addition, from an application of our method, it has been proven that one model can not encompass all other possible inconsistency patterns in responses. Test results show that the behavioral inconsistency patterns are different both within and between data sets

description: Tree fruits, including apples, pears, cherries, and other stone fruits, are economically important crops grown in temperate regions worldwide. These crops are vulnerable to various pests and vector-borne diseases that reduce productivity and profitability, leading to reliance on chemical controls. Some pests affect multiple tree fruit species, and their management is crucial for sustainable orchard production. Epigeic (living on or near soil surface) predatory arthropods, such as carabid beetles, harvestmen, centipedes, and spiders, are natural enemies that inhabit the orchard floor and play a vital role in pest suppression by preying on a range of species. This research identifies the epigeic predator taxa present in Washington State cherry orchards, and how ground cover management strategies may impact them.
description: In 2023, I conducted a survey across 13 sweet cherry orchards over a 300 km region of Washington State east of the Cascade mountains. Five of the orchards were certified organically managed, and eight were conventionally managed. Using pitfall traps, I sampled the epigeic predator community weekly from late April to early August, then at reduced frequency until September. The most abundant predators found were carabid beetles, harvestmen, centipedes, and spiders, all potential biological control agents of pests like spotted-wing drosophila, western cherry fruit fly, and leafhoppers, whose immature life stages occur in the soil or groundcover for a period of time ranging from days to months.
description: The second study assessed the effects of a reflective geotextile (Extenday®) on epigeic predator activity densities in post-harvest cherry orchards. In 2021 and 2022, pitfall traps compared predator activity densities in geotextile-treated, kaolin clay-treated (2021), herbicide-treated (2022), and untreated control plots. In 2021, significantly more carabid beetles and centipedes, but fewer harvestmen, were found in the geotextile-treated plots. In 2022, fewer harvestmen and spiders were observed in the geotextile-treated plots, but carabid beetle and centipede numbers showed no significant difference from the controls.
description: These findings suggest that reflective geotextiles may alter the groundcover environment, influencing predator composition and activity. Understanding these interactions can improve biological control integration and enhance sustainable pest management strategies in cherry orchards.
