description: We apply the K-correction to the black hole LMXB GX 339-4 which implies Mx > 6 Msun by only assuming that the companion is more massive than ~0.17 Msun, the lower limit allowed by applying a 'stripped-giant' model. This evolutionary model successfully reproduces the observed properties of the system. We obtain a maximum mass for the companion of M2 < 1.1 Msun and an upper limit to the mass ratio of q(=M2/Mx)< 0.125. The high X-ray activity displayed by the source suggests a relatively large mass transfer rate which, according to the model, results in M2 > 0.3 Msun and Mx > 7 Msun. We have also applied this scenario to the black hole binary XTE J1550-564, which has a similar orbital period but the donor is detected spectroscopically. The model successfully reproduces the observed stellar parameters.

description: Making use of the gauge/string duality, it is possible to study some aspects of the string breaking phenomenon in the three quark system. Our results point out that the string breaking distance is not universal and depends on quark geometry. The estimates of the ratio of the string breaking distance in the three quark system to that in the quark-antiquark system would range approximately from $\frac{2}{3}$ to $1$. In addition, it is shown that there are special geometries which allow more than one breaking distance.

description: We report on the time-resolved CCD photometry of a newly discovered variable star, TSS J022216.4+412259.9 during the outburst in 2005 November-December brightening. The obtained light curves unambiguously showed 0.2-0.3 mag modulations, which we confirmed to be the superhump observed among SU UMa-type dwarf novae. We also performed a period search for the data obtained during the outburst plateau phase, and revealed the existence of the two periodicities: 0.054868(98) days for the first two nights and 0.055544(26) days for the following plateau phase. This bi-periodicity is hardly observed in usual SU UMa-type dwarf novae, but characteristic of WZ Sge-type stars. We undoubtedly detected a rebrightening in the post-outburst stage, which is typical of short-period SU UMa-type dwarf novae including WZ Sge-type stars. These observations suggests that TSS J022216.4+412259.9 may be a new WZ Sge stars breaking the shortest superhump period of 0.05648 days for V592 Her among this class with a known superhump period so far.

description: We demonstrate dispersive readout of individual charge states in a gate-defined few-electron quantum dot in bilayer graphene. We employ a radio frequency reflectometry circuit, where an LC resonator with a resonance frequency close to 280 MHz is directly coupled to an ohmic contact of the quantum dot device. The detection scheme based on changes in the quantum capacitance operates over a wide gate-voltage range and allows to probe excited states down to the single-electron regime. Crucially, the presented sensing technique avoids the use of an additional, capacitively coupled quantum device such as a quantum point contact or single electron transistor, making dispersive sensing particularly interesting for gate-defined graphene quantum dots.

Reviewable transactions in insolvency : the recognition of creditors’ interests in "subjective" and "objective" insolvency regimes
Creators: name: Horne, Andrew J.
Publisher: name: University of British Columbia
Year: 2009

description: A person on the eve of bankruptcy may enter into transactions or arrangements that are intended to, or that have the effect of, preserving its property from being seized and distributed among creditors. Such transactions may provide a bankrupt with collateral benefits such as the continued use and enjoyment of property, or they may benefit third parties such as members of the bankrupt's family, or they may benefit selected creditors to the detriment of others. The effect of such transactions is to frustrate the legislative scheme which provides for the distribution of a bankrupt's residual property. This effect may be desired by a bankrupt or by a recipient of the bankrupt's property, or it may be unintended. Insolvency legislation confers wide powers upon a trustee in bankruptcy to "review" such transactions by bringing proceedings to reverse their effect and recover the value lost to the bankrupt's estate. Reviewable transactions comprise two main categories: dispositions or unequal transactions in which a debtor parts with property for no or insufficient consideration (such as a transfer of property to a spouse or a sale in which a bankrupt does not receive a fair price) and preferential repayments of debts owed to certain creditors to the detriment of others. Reviewable transaction laws in Canada and England have a subjective basis in that they focus upon the intent of a debtor to defeat creditors or prefer one creditor over others. In contrast, relevant Australian and New Zealand laws have an objective focus and provide remedies where the effect of a transaction, rather than the intent of a debtor, is to defeat the interests of creditors. This paper conducts a comparative critique of reviewable transaction regimes. It makes the argument that subjective regimes tend to reflect their historical origins in fraud law and a desire to punish and frustrate the fraudulent intent of a bankrupt; an inappropriate policy foundation that fails to address the competing interests and policy considerations which should form the basis of reviewable transaction law. Objective regimes, which focus upon the effect of impugned transactions, provide more appropriately for the balancing of creditors' and recipients' interests and the making of provision for policy considerations. This paper also considers collateral effects of reviewable transaction regimes upon creditors' interests (such as effects upon claims to property recovered by a trustee) in a variety of circumstances and concludes that the results are often inconsistent and undesirable. In this respect the relative positions of secured and unsecured creditors are described in detail and proposals for reform are ventured.

description: Combining the recent Piskulich-Thompson approach [Z. A. Piskulich and W. H. Thompson, {\it J. Chem. Phys.} {\bf 152}, 011102 (2020)] with isomorph theory, from a single simulation, the structure of a single-component Lennard-Jones (LJ) system is obtained at an arbitrary state point in almost the whole liquid region of the temperature-density phase diagram. The LJ system exhibits two temperature range where the van't Hoff's assumption that energetic and entropic forces are temperature independent is valid. A method to evaluate the structure at an arbitrary state point along an isochore from the knowledge of structures at two temperatures on the isochore is also discussed. We argue that, in general, the structure of any hidden scale-invariant system obeying the van't Hoff's assumption in the whole range of temperatures can be determined in the whole liquid region of the phase diagram from only a single simulation.

description: Fermi-surface deformations in strongly correlated metals, in comparison to results from band-structure calculations, are investigated. We show that correlation-induced interband charge transfers in multi-orbital systems may give rise to substantial modifications of the actual Fermi surface. Depending in particular on the relative strength of the crystal-field splitting and of the Hund's exchange coupling, correlations may either reinforce orbital polarization or tend to compensate differences in orbital occupancies, as demonstrated by investigating a 2-band Hubbard model in the framework of dynamical mean field theory (DMFT). The physical implications of such interorbital charge transfers are then explored in two case studies: BaVS$_3$ and Na$_x$CoO$_2$. By means of the DMFT in combination with the local density approximation (LDA) to density functional theory (DFT), new insights in the underlying mechanism of the metal-to-insulator transition (MIT) of BaVS$_3$ are obtained. A strong charge redistribution in comparison to LDA calculations, i.e., a depletion of the broader $A_{1g}$ band in favor of the narrower $E_g$ bands just above the MIT is found. In addition, the intriguing problem of determining the Fermi surface in the strongly correlated cobaltate system Na$_{x}$CoO$_2$ is discussed.

description: Fish swim by undulating their bodies. These propulsive motions require coordinated shape changes of a body that interacts with its fluid environment, but the specific shape coordination that leads to robust turning and swimming motions remains unclear. To address the problem of underwater motion planning, we propose a simple model of a three-link fish swimming in a potential flow environment and we use model-free reinforcement learning for shape control. We arrive at optimal shape changes for two swimming tasks: swimming in a desired direction and swimming towards a known target. This fish model belongs to a class of problems in geometric mechanics, known as driftless dynamical systems, which allow us to analyze the swimming behavior in terms of geometric phases over the shape space of the fish. These geometric methods are less intuitive in the presence of drift. Here, we use the shape space analysis as a tool for assessing, visualizing, and interpreting the control policies obtained via reinforcement learning in the absence of drift. We then examine the robustness of these policies to drift-related perturbations. Although the fish has no direct control over the drift itself, it learns to take advantage of the presence of moderate drift to reach its target.

description: Diagnostic characters of Clematis armandi
Clematis armandi is widely distributed in China, Myanmar, and Vietnam. In China, it occurs in Chongqing, southwestern and northern Fujian, southern Gansu, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangxi, southern Shaanxi, Sichuan, eastern Xizang, Yunnan, and southern Zhejiang (Huang et al. 2024b). Morphologically, this species is well characterized by being woody vines and by having ternate leaves, leaflets entire, ovate-lanceolate, oblong-ovate to ovate, glabrous on both surfaces, conspicuous scales of axillary buds often present at the base of cymes, pedicels not bracteolate, stamens glabrous, filaments not rugose, anthers narrowly oblong to linear (Chang 1980, Wang & Bartholomew 2001, Huang et al. 2024b). Moreover, C. armandi is a spring-flowering species, usually in full blossom from March to April. The type specimens of C. armandi and five non-type specimens from the type locality, i.e. Baoxing county in western Sichuan, are shown in Figures 22, 23. It is to be noted that although the presence of large scales at the base of cymes is one of the most important diagnostic characters of C. armandi, this character often does not occur or at least is not conspicuous on some branches, particularly on those of current year (Huang et al. 2024b; Fig. 22A–D).
All these diagnostic characters of Clematis armandi have been confirmed by our observations of living plants within the six populations we visited in 2024 (Table 1; Figs. 6–21). The plants are woody vines; leaves are ternate; leaflets are entire, ovate-lanceolate, oblong-ovate to ovate, glabrous on both surfaces; large scales of axillary buds are present at the base of cymes borne on branches of last years, but often absent on branches of current year; pedicels are not bracteolate; stamens are glabrous, with filaments not rugose, anthers narrowly oblong to linear. The plants are usually in full blossom from March to April.

description: The mechanical behaviour of Mg-Al alloys can be largely improved by the formation of an intermetallic Laves phase skeleton, in particular the creep strength. Recent nanomechanical studies revealed plasticity by dislocation glide in the (Mg,Al)$_2$Ca Laves phase, even at room temperature. As strengthening skeleton, this phase remains, however, brittle at low temperature. In this work, we present experimental evidence of slip transfer from the Mg matrix to the (Mg,Al)$_2$Ca skeleton at room temperature and explore associated mechanisms by means of atomistic simulations. We identify two possible mechanisms for transferring Mg basal slip into Laves phases depending on the crystallographic orientation: a direct and an indirect slip transfer triggered by full and partial dislocations, respectively. Our experimental and numerical observations also highlight the importance of interfacial sliding that can prevent the transfer of the plasticity from one phase to the other.

description: Visual Teach and Repeat has shown relative navigation is a robust and efficient solution for autonomous vision-based path following in difficult environments. Adding additional absolute sensors such as Global Navigation Satellite Systems (GNSS) has the potential to expand the domain of Visual Teach and Repeat to environments where the ability to visually localize is not guaranteed. Our method of lazy mapping and delaying estimation until a path-tracking error is needed avoids the need to estimate absolute states. As a result, map optimization is not required and paths can be driven immediately after being taught. We validate our approach on a real robot through an experiment in a joint indoor-outdoor environment comprising 3.5km of autonomous route repeating across a variety of lighting conditions. We achieve smooth error signals throughout the runs despite large sections of dropout for each sensor.

description: We present a method to accelerate global illumination computation in dynamic environments by taking advantage of limitations of the human visual system. A model of visual attention is used to locate regions of interest in a scene and to modulate spatiotemporal sensitivity. The method is applied in the form of a spatiotemporal error tolerance map. Perceptual acceleration combined with good sampling protocols provide a global illumination solution feasible for use in animation. Results indicate an order of magnitude improvement in computational speed. The method is adaptable and can also be used in image-based rendering, geometry level of detail selection, realistic image synthesis, video telephony and video compression.

description: The interference between Compton scattering and nonlinear Compton scattering from a two-color field in the X-ray regime is theoretically examined for bound electrons. The underlying phase shifts are analysed using a perturbative approach in the incoming classical field. The perturbative approach is bench marked with a non-perturbative approach in the classical field. The interference for different combinations of linear polarization of the two fields is examined when the Compton and the nonlinear Compton scattered waves have the same wave vector and polarization. Only two cases exhibit interference. When there is interference, the calculations reveal an intrinsic phase difference between the Compton scattered wave function and the nonlinear Compton scattered wave function of either 0 or $π$ depending on the scattering angle.

description: We present the results of an all-sky search for continuous gravitational wave signals with frequencies in the 1700-2000 Hz range from neutron stars with ellipticity of 1e-8. The search employs the Falcon analysis pipeline [citation 5] on LIGO O2 public data. Our results improve by a factor greater than 5 over [citation 11]. This is a huge leap forward: it takes an entirely new generation of gravitational wave detectors to achieve a 10-fold sensitivity increase over the previous generation [citation 12]. Within the probed frequency range and aside from the detected outliers, we can exclude neutron stars with ellipticity of 1e-8 within 65 pc of Earth. We set upper limits on the gravitational wave amplitude that hold even for worst-case signal parameters. New outliers are found, some of which we are unable to associate with any instrumental cause. If any were associated with a rotating neutron star, this would likely be the fastest neutron star today.

description: In individuals living with obesity, adipose tissue aids in reducing (H_loss) and also serves as a heat storage compartment. Moreover, lean body mass, which has a higher H_prod than adipose tissue plays a crucial role in energy production and thermoregulation. The extent of resistance to the cold remains underexplored in this population, and it is important to understand these responses given the global obesity rise and its health implications. This study aimed to quantify how various body anthropometric variations affected thermal responses in individuals living with obesity during acute compensable cold exposure. A liquid-conditioned suit, connected to a temperature-controlled water circulating bath set at 10°C, was used for 90 min to elicit a compensable cold response in these individuals. Validated methods regarding subjective thermal comfort and sensations, skin temperature (T_skin; °C), heat production (H_prod; kJ ⋅min⁻¹), metabolic fuel selection and shivering intensity were recorded to determine the effect of obesity (and muscle and fat mass) on thermogenic and thermal responses. Our study revealed that individuals with obesity, like their lean counterparts, manifest an increased H_prod during cold exposure by 1.7 ± 1.3 kJ ⋅min⁻¹. However, this increase was observed to be lesser in magnitude among individuals living with obesity compared to lean ones. We also explored the source of fuel during cold exposure and found that carbohydrate and lipid oxidation collectively accounted for a significant proportion of H_prod, with lipid oxidation dominating at 61%, and carbohydrates at 21%. Regarding muscle activity, it was observed that a decrease in T_skin incited an increase in shivering. However, similar to the metabolic responses, shivering in this cohort was much less pronounced than in lean individuals. The study opens avenues for further research, addressing the implications of repeated cold exposure and different lengths, temperatures, or modalities on individuals living with obesity.

description: Based on interaction potentials between a heavy quark and antiquark as extracted from recent QCD lattice calculations, we set up a Brueckner-type many-body scheme to study the properties of light (anti-) quarks in a Quark-Gluon Plasma at moderate temperatures, $T\simeq$ 1-2 $T_c$. The quark-antiquark $T$-matrix, including both color-singlet and -octet channels, and corresponding quark self-energies and spectral functions are calculated self-consistently. The repulsive octet potential induces quasiparticle masses of up to 150 MeV, whereas the attractive color-singlet part generates resonance structures in the $q$-$\bar q$ $T$-matrix, which in turn lead to quasiparticle widths of $\sim$200 MeV. This corresponds to scattering rates of $\sim$1 fm$^{-1}$ and may reflect liquid-like properties of the system.

description: The design of medium access control protocols for a cognitive user wishing to opportunistically exploit frequency bands within parts of the radio spectrum having multiple bands is considered. In the scenario under consideration, the availability probability of each channel is unknown a priori to the cognitive user. Hence efficient medium access strategies must strike a balance between exploring the availability of channels and exploiting the opportunities identified thus far. Using a sequential design approach, an optimal medium access strategy is derived. To avoid the prohibitive computational complexity of this optimal strategy, a low complexity asymptotically optimal strategy is also developed. The proposed strategy does not require any prior statistical knowledge about the traffic pattern on the different channels.

Considering such tasks in the context of AdS/CFT has led to novel constraints relating bulk geometry and boundary entanglement. In this article we consider tasks where inputs and outputs are encoded into extended spacetime regions, rather than the points previously considered. We show that this leads to stronger constraints than have been derived in the point based setting. In particular we improve the connected wedge theorem, appearing earlier in 1912.05649, by finding a larger bulk region whose existence implies large boundary correlation. As well, we show how considering extended input and output regions leads to non-trivial statements in Poincaré-AdS$_{2+1}$, a setting where the point-based connected wedge theorem is always trivial.

description: We study the localization properties of disordered semiconductor superlattices driven by ac-fields. The localization length of the electrons in the superlattice increases when the frequency of the driving field is smaller than the miniband width. We show that there is an optimal value of the amplitude of the driving field for which the localization length of the system is maximal. This maximum localization length increases with the inverse of the driving frequency.

description: Cracking of rocks and rock-like materials exhibits a rich variety of patterns where tensile (mode I) and shear (mode II) fractures are often interwoven. These mixed-mode fractures are usually cohesive (quasi-brittle) and frictional. Although phase-field modeling is increasingly used for rock fracture simulation, no phase-field formulation is available for cohesive and frictional mixed-mode fracture. To address this shortfall, here we develop a double-phase-field formulation that employs two different phase fields to describe cohesive tensile fracture and frictional shear fracture individually. The formulation rigorously combines the two phase fields through three approaches: (i) crack-direction-based decomposition of the strain energy into the tensile, shear, and pure compression parts, (ii) contact-dependent calculation of the potential energy, and (iii) energy-based determination of the dominant fracturing mode in each contact condition. We validate the proposed model, both qualitatively and quantitatively, with experimental data on mixed-mode fracture in rocks. The validation results demonstrate that the double-phase-field model -- a combination of two quasi-brittle phase-field models -- allows one to directly use material strengths measured from experiments, unlike brittle phase-field models for mixed-mode fracture in rocks. Another standout feature of the double-phase-field model is that it can simulate, and naturally distinguish between, tensile and shear fractures without complex algorithms.
Very Simple Chaitin Machines for Concrete AIT

description: In 1975, Chaitin introduced his celebrated Omega number, the halting probability of a universal Chaitin machine, a universal Turing machine with a prefix-free domain. The Omega number's bits are {\em algorithmically random}--there is no reason the bits should be the way they are, if we define ``reason'' to be a computable explanation smaller than the data itself. Since that time, only {\em two} explicit universal Chaitin machines have been proposed, both by Chaitin himself. Concrete algorithmic information theory involves the study of particular universal Turing machines, about which one can state theorems with specific numerical bounds, rather than include terms like O(1). We present several new tiny Chaitin machines (those with a prefix-free domain) suitable for the study of concrete algorithmic information theory. One of the machines, which we call Keraia, is a binary encoding of lambda calculus based on a curried lambda operator. Source code is included in the appendices. We also give an algorithm for restricting the domain of blank-endmarker machines to a prefix-free domain over an alphabet that does not include the endmarker; this allows one to take many universal Turing machines and construct universal Chaitin machines from them.

description: The topological Hochschild homology THH(R) of a commutative S-algebra (E_infty ring spectrum) R naturally has the structure of a commutative R-algebra in the strict sense, and of a Hopf algebra over R in the homotopy category. We show, under a flatness assumption, that this makes the Boekstedt spectral sequence converging to the mod p homology of THH(R) into a Hopf algebra spectral sequence. We then apply this additional structure to the study of some interesting examples, including the commutative S-algebras ku, ko, tmf, ju and j, and to calculate the homotopy groups of THH(ku) and THH(ko) after smashing with suitable finite complexes. This is part of a program to make systematic computations of the algebraic K-theory of S-algebras, by means of the cyclotomic trace map to topological cyclic homology.

description: The transit method of exoplanet discovery and characterization has enabled numerous breakthroughs in exoplanetary science. These include measurements of planetary radii, mass-radius relationships, stellar obliquities, bulk density constraints on interior models, and transmission spectroscopy as a means to study planetary atmospheres. The Transiting Exoplanet Survey Satellite (TESS) has added to the exoplanet inventory by observing a significant fraction of the celestial sphere, including many stars already known to host exoplanets. Here we describe the science extraction from TESS observations of known exoplanet hosts during the primary mission. These include transit detection of known exoplanets, discovery of additional exoplanets, detection of phase signatures and secondary eclipses, transit ephemeris refinement, and asteroseismology as a means to improve stellar and planetary parameters. We provide the statistics of TESS known host observations during Cycle 1 & 2, and present several examples of TESS photometry for known host stars observed with a long baseline. We outline the major discoveries from observations of known hosts during the primary mission. Finally, we describe the case for further observations of known exoplanet hosts during the TESS extended mission and the expected science yield.

description: We describe the structure of those graphs that have largest spectral radius in the class of all connected graphs with a given degree sequence. We show that in such a graph the degree sequence is non-increasing with respect to an ordering of the vertices induced by breadth-first search. For trees the resulting structure is uniquely determined up to isomorphism. We also show that the largest spectral radius in such classes of trees is strictly monotone with respect to majorization.
description: 12 pages, 4 figures; revised version. Important change: Theorem 3 (formely Theorem 7) now states (and correctly proofs) the majorization result only for "degree sequences of trees" (instead for general connected graphs). Bo Zhou from the South China Normal University in Guangzhou, P.R. China, has found a counter-example to the stronger result
Screening for psychological distress in newly diagnosed cancer patients

description: The present research explored screening for psychosocial distress in newly diagnosed cancer patients. In particular this research examined the use of the Distress Thermometer, the SPHERE-SF12, the DASS-42, and the SCNS in screening for psychosocial distress in this population. The utility of the Distress Thermometer was compared against the SPHERE-SF12, in terms of both instruments ability to detect psychological distress 'caseness'. The utility of the SPHERE-SF12 was also explored in terms of its ability to measure psychological morbidity in relation to participant scores for depression, anxiety, and stress on the DASS-42. Also examined was the acceptability of psychosocial screening to newly diagnosed cancer patients. Two studies were conducted as part of this research. Study 1 included 163 newly diagnosed cancer patients and sought to investigate the utility and feasibility of the introduction of a routine standardised psychosocial screening program for all newly diagnosed patients at participating oncology clinics within the ACT. The introduction of a psychological screening program explored rates of referral to psychosocial services, both prior to and following introduction of a screening program, as well as patient (participant) attitudes towards screening and acceptability of psychosocial screening by participants. The effectiveness of the Distress Thermometer, the DASS-42, and the SPHERE-SF12 as a screening tool for psychological distress was demonstrated. The use of the Distress Thermometer as a mechanism of referral to psychosocial services was demonstrated, with an increase in direct referrals to psychosocial services following its introduction. Participant responses indicated that psychosocial screening was acceptable, with participants reporting a positive attitude towards psychosocial screening. Study 2 included 118 participants from Study 1, and sought to investigate the level of unmet supportive care needs in newly diagnosed cancer patients, at six months following their initial visit to the oncology clinic, using the Supportive Care Needs Survey Short Form 34 (SCNS-SF34). Participant scores on the SCNS-SF34 revealed the highest areas of unmet were in the psychological and health system and information domains. These results are in line with other research into supportive care needs, which have also reported levels of unmet need in these areas. Statistical analysis also revealed significant correlations on all of the domains in the SCNS-SF34.
Analytic energy, gradient, and hessian of electrostatic embedding QM/MM based on electrostatic potential fitted atomic charges scaling linearly with the MM subsystem size

description: Electrostatic potential fitting method (ESPF) is a powerful way of defining atomic charges derived from quantum density matrices fitted to reproduce a quantum mechanical charge distribution in the presence of an external electrostatic potential. These can be used in the Hamiltonian to define a robust and efficient electrostatic embedding QM/MM method. The original formulation of ESPF QM/MM contained two main approximations, namely, the neglect of grid derivatives and the non-conservation of the total QM charge. Here, we present a new ESPF atomic charge operator which solves these drawbacks at virtually no extra computational cost. The new charge operators employ atom-centered grids and conserve the total charge when traced with the density matrix. We present an efficient and easy-to-implement analytic form for the energy, gradient, and hessian that scale linearly with the MM subsystem size. We show that grid derivatives and charge conservation are fundamental to preserve the translational invariance properties of energies and its derivatives and exact conditions to be satisfied by the atomic charge derivatives. As proof of concept, we compute the transition state that leads to the formation of hydrogen peroxide during cryptochrome's reoxidation reaction. Last, we show that the construction of the full QM/MM hessian scales linearly with the MM subsystem size.

description: Several methods are constructed for large-scale electronic structure calculations. Test calculations are carried out with up to 10^7 atoms. As an application, cleavage process of silicon is investigated by molecular dynamics simulation with 10-nm-scale systems. As well as the elementary formation process of the (111)-(2 x 1) surface, we obtain nanoscale defects, that is, step formation and bending of cleavage path into favorite (experimentally observed) planes. These results are consistent to experiments. Moreover, the simulation result predicts an explicit step structure on the cleaved surface, which shows a bias-dependent STM image.
