description: Until now, researchers have proposed several novel heterogeneous defect prediction HDP methods with promising performance. To the best of our knowledge, whether HDP methods can perform significantly better than unsupervised methods has not yet been thoroughly investigated. In this article, we perform a replication study to have a holistic look in this issue. In particular, we compare state-of-the-art five HDP methods with five unsupervised methods. Final results surprisingly show that these HDP methods do not perform significantly better than some of unsupervised methods (especially the simple unsupervised methods proposed by Zhou et al.) in terms of two non-effort-aware performance measures and four effort-aware performance measures. Then, we perform diversity analysis on defective modules via McNemar's test and find the prediction diversity is more obvious when the comparison is performed between the HDP methods and the unsupervised methods than the comparisons only between the HDP methods or between the unsupervised methods. This shows the HDP methods and the unsupervised methods are complementary to each other in identifying defective models to some extent. Finally, we investigate the feasibility of five HDP methods by considering two satisfactory criteria recommended by previous CPDP studies and find the satisfactory ratio of these HDP methods is still pessimistic. The above empirical results implicate there is still a long way for heterogeneous defect prediction to go. More effective HDP methods need to be designed and the unsupervised methods should be considered as baselines.

description: The $ρ^0-ω$ interference has been studied in the dilepton invariant mass distribution spectra in the photonuclear reaction, but that is not done for the gamma-nucleon reaction. Recent past, the $e^+e^-$ invariant mass distribution spectrum in the $γp$ reaction, i.e., $γp \to pe^+e^-$ reaction, was measured at Jefferson Laboratory to look for the $ρ^0 -ω$ interference in the multi-GeV region. To study the mechanism of this reaction, the differential cross section of the $e^+e^-$ invariant mass distribution is calculated in the quoted energy region. The reaction is assumed to proceed as $γp \to Vp$; $V \to e^+e^-$, where $V$ denotes a vector meson, i.e., either $ρ^0$ or $ω$ meson. The photoproduction of the vector meson is described by the Vector Meson Dominance (VMD) model which consists of diagonal and off-diagonal processes. The diagonal process is described as $γ\to V; ~Vp \to Vp$. The low energy $ω$ meson photoproduction data is well described by the off-diagonal process which is illustrated as $γ\to ρ^0; ~ρ^0 p \to ωp$. The reaction $ρ^0p \to ωp$ proceeds due to one pion exchange interaction. The differential cross sections of the $γp \to pe^+e^-$ reaction due to the above processes of VMD model are compared, and the significance of the pion exchange interaction is investigated in the energy region of $γ$ beam available at Jefferson Laboratory.

description: We translate the action of local Clifford operations on graph states into transformations on their associated graphs - i.e. we provide transformation rules, stated in purely graph theoretical terms, which completely characterize the evolution of graph states under local Clifford operations. As we will show, there is essentially one basic rule, successive application of which generates the orbit of any graph state under local unitary operations within the Clifford group.

description: Spatial models for spread of an epidemic may be mapped onto bond percolation. We point out that with disorder in the strength of contacts between individuals patchiness in the spread of the epidemic is very likely, and the criterion for epidemic outbreak depends strongly on the disorder because the critical region of the corresponding percolation model is broadened. In some networks the percolation threshold is zero if another kind of disorder is present, namely divergent fluctuations in the number of contacts. We give an example, a network with a well defined geography, where this is not necessarily so, and discuss whether real infection networks are likely to have this property.

description: Results of the spectral analysis for the galaxy cluster IGR J17448-3232 are presented. The intracluster medium (ICM) in the central region (r<300", 320 kpc) has a high electron temperature plasma of kTe~13-15 keV and an ionization temperature estimated from an intensity ratio of Fe XXVI Ly alpha/Fe XXV He alpha lines is lower than the electron temperature, which suggests that the ICM is in the non-ionization equilibrium (NEI) state. The spectrum in the central region can be also fitted with a two-component model: a two-temperature plasma model in a collisional ionization equilibrium (CIE) with temperatures of 7.9 keV and >34 keV or a CIE+power law model with a temperature of 9.4 keV and a photon index of 1.1. The two component models can represent the intensity ratio of Fe XXVI Ly alpha/Fe XXV He alpha lines. On the other hand, the spectrum in the outer region (r>300'') can be explained by a single CIE plasma model with a temperature of 5-8 keV. Based on the spectral feature and its circular structure, we propose that the NEI plasma was produced by merging along the line-of-sight direction.

description: Recent experimental results in proton-proton and in proton-nucleus collisions at Large Hadron Collider energies show a strong similarity to those observed in nucleus-nucleus collisions, where the formation of a quark-gluon plasma is expected. We discuss the comparison between small colliding systems and nucleus-nucleus collisions, for: a)~the strangeness suppression factor $γ_s$ and yields of multi-strange hadrons; b)~the average transverse momentum, $p_t$, with particular attention to the low $p_t$ region where soft, non-perturbative effects are important; c)~the elliptic flow scaled by the participant eccentricity. The universal behavior in hadronic and nuclear high energy collisions emerges for all these observables in terms of a specific dynamical variable which corresponds to the entropy density of initial system in the collision and which takes into account the transverse size of the initial configuration and its fluctuations.

description: A series of novel 3-benzimidazolyl retrochalcones (6a–g) was synthesized and evaluated for their anticancer activities against breast (MDA-MB-231, MCF-7) and human colon (Caco-2, HCT-116) cancer cell lines. The compounds demonstrated significant anticancer potential, with compound 6d exhibiting the most potent activity (IC50 < 1.56 μM) across all tested cell lines. Most compounds were more active than Roscovitine but less potent than Paclitaxel (Taxol®). Notably, compound 6e was inactive against both Caco-2 and MDA-MB-231 cell lines. The presence of electron-donating methoxy groups enhanced anticancer efficacy, while electron-withdrawing nitro groups had a detrimental effect. The high amplitude values (70%–98%) observed for the compounds indicate effective targeting of cancer cells, while lower amplitudes in fibroblasts (27%–49%) suggest selective antimitotic effects. These findings highlight the potential of benzimidazole-supported retrochalcones as promising candidates for further development as broad anticancer agents.

Endrödi (1985) constitutes the most recent comprehensive taxonomic review of the Dynastinae, in which he provides the following morphological description of the Dynastini relative to the other tribes of the subfamily: “This tribe includes the biggest species of the whole family Melolonthidae. Most species display very strong sexual dimorphism. Horns of males often very long, head and pronotum [horns] in females usually almost absent. Fore legs of males mostly longer than in females. Also elytra in many species different: in male smooth, in female strongly sculptured. Mandibles mostly incised on apex, outer side straight or lobed. Antennae 10-jointed, club in both sexes short. Form of prosternal process highly variable. Propygidium either with or without a stridulatory area. Claw-joint of anterior tarsi strongly thickened only in Dynastes neptunus Quensel and D. satanas Moser; apex of basal-joint of hind tarsi rarely spiniformly produced.”

title: Futures Markets, Oil Prices and the Intertemporal Approach to the Current Account
Creators: name: Arbatli, Elif
Publisher: name: Bank of Canada
Year: 2008

description: The intertemporal approach to the current account suggests modeling movements in the current account in a forward-looking, dynamic framework. In this framework, the current account reflects consumption smoothing of agents that lend and borrow from the rest of the world in the face of transitory shocks to income. As in permanent income models of consumption, the marginal propensity to consume out of transitory shocks is predicted to be significantly smaller which implies that a permanent income shock has a smaller effect on the current account than a transitory income shock. I use the term structure of petroleum futures to identify permanent and transitory innovations to petroleum prices. Then, I formulate a test of the intertemporal approach to the current account based on how a group of nineteen small petroleum exporters respond to each type of income shock. This market-based identification of income shocks and their perceived persistence offers a transparent framework for investigating the empirical evidence for the intertemporal approach. As the theory predicts, petroleum exporters have a significantly higher marginal propensity to consume out of permanent oil price shocks than out of transitory oil price shocks.
description: L'approche intertemporelle de la balance des paiements courants propose de modéliser les mouvements de cette balance dans un cadre dynamique prospectif. Dans un tel cadre, l'évolution de la balance courante reflète le fait que les agents amortissent l'incidence des chocs temporaires de revenu sur leur consommation en prêtant ou en empruntant des fonds à l'étranger. À l'instar des modèles de consommation inspirés de la théorie du revenu permanent, le modèle intertemporel prédit que la propension marginale à consommer un dollar supplémentaire de revenu est nettement plus faible si le choc est transitoire : une variation permanente du revenu aurait ainsi moins d'effet sur la balance courante qu'une variation temporaire. L'auteure se sert de la structure par échéance des prix des contrats à terme du pétrole pour distinguer les chocs permanents et transitoires des prix de l'or noir. Elle élabore ensuite un test de l'approche intertemporelle qui consiste à étudier la réaction d'un groupe de dix-neuf petits exportateurs de pétrole aux deux types de chocs de revenu. L'identification des chocs de revenu et de leur degré de persistance aux yeux du marché fournit un cadre transparent d'analyse des résultats empiriques. Comme le prévoit la théorie, la propension marginale à consommer des exportateurs de pétrole est bien plus élevée quand le choc pétrolier est permanent.
Nuclear incompressibility using the density dependent M3Y effective interaction

description: A density dependent M3Y effective nucleon-nucleon (NN) interaction which was based on the G-matrix elements of the Reid-Elliott NN potential has been used to determine the incompressibity of infinite nuclear matter. The nuclear interaction potential obtained by folding in the density distribution functions of two interacting nuclei with this density dependent M3Y effective interaction had been shown earlier to provide excellent descriptions for medium and high energy $α$ and heavy ion elastic scatterings as well as $α$ and heavy cluster radioactivities. The density dependent parameters have been chosen to reproduce the saturation energy per nucleon and the saturation density of spin and isospin symmetric cold infinite nuclear matter. The result of such calculations for nuclear incompressibility using the density dependent M3Y effective interaction based on the G-matrix elements of Reid-Elliott NN potential predicts a value of about 300 MeV for nuclear incompressibility.

description: Context. The study of linear waves and instabilities is necessary to understand the physical evolution of an atmosphere, and can provide physical interpretation of the complex flows found in simulations performed using Global Circulation Models (GCM). In particular, the acceleration of superrotating flow at the equator of hot Jupiters has mostly been studied under several simplifying assumptions, the relaxing of which may impact final results. Aims. We develop and benchmark a publicly available algorithm to identify the eigenmodes of an atmosphere around any initial steady state. We also solve for linear steady states. Methods. We linearise the hydrodynamical equations of a planetary atmosphere in a steady state with arbitrary velocities and thermal profile. We then discretise the linearised equations on an appropriate staggered grid, and solve for eigenvectors and linear steady solutions with the use of a parallel library for linear algebra: ScaLAPACK. We also implement a posteriori calculation of an energy equation in order to obtain more information on the underlying physics of the mode. Results. Our code is benchmarked against classical wave and instability test cases in multiple geometries. The steady linear circulation calculations also reproduce expected results for the atmosphere of hot Jupiters. We finally show the robustness of our energy equation, and its power to obtain physical insight into the modes. Conclusions. We have developed and benchmarked a code for the study of linear processes in planetary atmospheres, with an arbitrary steady state. The calculation of an a posteriori energy equation provides both increased robustness and physical meaning to the obtained eigenmodes. This code can be applied to various problems, and notably to further study the initial spin up of superrotation of GCM simulations of hot Jupiter.

description: In the pursuit of sustainable methodologies in organic synthesis, the application of renewable and biodegradable catalysts has received significant attention. This work processes the synthesizing of 3,4-dihydropyrimidin-2(1H)-ones/thiones using L-arabinose, an environment-friendly catalyst via the Biginelli reaction in a solvent-free environment is reported herein. L-arabinose, a naturally occurring sugar, efficiently catalyzes the condensation reaction between β-ketoesters and aldehyde with urea or thiourea to form DHPMs with high yields and excellent atom economy. The reaction proceeds efficiently at mild temperatures, and the catalyst is easily regenerated, enabling multiple catalytic cycles. The use of L-arabinose avoids not only toxic solvents and metal catalysts but also processes green chemistry due to the exploitation of renewable resources. It is a significant step forward in the domain of sustainable catalysis and provides an environmentally benign and operationally simple procedure for the synthesis of DHPMs.

Publisher: name: Bank of Canada
Year: 2008

description: This paper develops a search-theoretic model to study the interaction between banking and monetary policy and how this interaction affects the allocation and welfare. Regarding how banking affects the welfare costs of inflation: First, we find that, with banking, inflation generates smaller welfare costs. Second, we show that, lowering inflation improves welfare not just by reducing consumption/production distortions, but also by avoiding intermediation costs. Therefore, understanding the nature of intermediation cost is critical for accurately assessing the welfare gain of lowering the inflation target. Regarding how monetary policy affects the welfare effects of banking: First, banking always improves efficiency of production, but the banking technology has to be efficient to improve welfare (especially in low inflation economy). Second, welfare effects of banking depend on monetary policy. For low inflation, banking is not active. For high inflation, banking is active and improves welfare. For moderate inflation, banking is active but reduces welfare. Owing to general equilibrium feedback, banking is supported in equilibrium even though welfare is higher without banking.
description: Les auteurs élaborent un modèle théorique de recherche afin d'étudier l'interaction entre l'activité bancaire et la politique monétaire, tout comme l'incidence de cette interaction sur l'allocation des ressources et le bien-être. L'activité bancaire est un facteur d'atténuation : c'est la première conclusion que les auteurs tirent de l'analyse du rôle de l'activité bancaire au regard des coûts de l'inflation sur le plan du bien-être. Ils montrent en second lieu qu'abaisser l'inflation accentue le bien-être, non seulement parce que cette action réduit les distorsions de la consommation et de la production, mais encore parce qu'elle permet d'éviter les coûts d'intermédiation. Saisir, par conséquent, la nature du coût d'intermédiation est capital si l'on veut évaluer au plus près le gain de bien-être attendu d'une cible d'inflation moins élevée. S'agissant de la façon dont la politique monétaire modifie les effets de l'activité bancaire sur le bien-être, les auteurs font deux constats. D'abord, si l'intermédiation bancaire améliore toujours l'efficience productive, le bien-être n'augmente cependant qu'à condition que les banques disposent d'une technologie efficiente (surtout au sein d'une économie à basse inflation). Ensuite, les effets de l'activité bancaire sur le bien-être dépendent de la politique monétaire. Ainsi, l'intermédiation est limitée en régime de basse inflation mais s'accroît et favorise le bien-être quand l'inflation est forte; à un taux d'inflation modéré, elle est dynamique mais diminue le bien-être. L'enchaînement d'effets, révélé à l'équilibre général, explique que l'activité bancaire soit soutenue à l'équilibre même si, sans elle, le bien-être progresserait.

description: Turbulence plays a major role in shaping marine community structure as it affects organism dispersal and guides fundamental ecological interactions. Below oceanographic mesoscale dynamics, turbulence also impinges on subtle physical-biological coupling at the single cell level, setting a sea of chemical gradients and determining microbial interactions with profound effects on scales much larger than the organisms themselves. It has been only recently that we have started to disentangle details of this coupling for swimming microorganisms. However, for non-motile species, which comprise some of the most abundant phytoplankton groups on Earth, a similar level of mechanistic understanding is still missing. Here, we explore by means of extensive numerical simulations the interplay between buoyancy regulation in non-motile phytoplankton and cellular responses to turbulent mechanical cues. Using a minimal mechano-response model, we show how such a mechanism would contribute to spatial heterogeneity and affect vertical fluxes and trigger community segregation.

This species was recently described from Cambodia and Malaysia. In Vietnam, it grows along a valley in damp tropical forests as lithophytes and is frequently submerged in water.
Specimens examined.

Note.
Morphologically, this species closely resembles Lindsaea ensifolia. Although L. kohkongensis is usually a much smaller species than L. ensifolia, we did not identify any qualitative trait to distinguish them. Currently, subaquatic habitat preference appears to be the most reliable characteristic for differentiating this species from L. ensifolia. Yun et al. (2023) described L. kohkongensis as having free venation, in contrast to the anastomosing venation found in L. ensifolia. However, this is not true. As demonstrated in Fig. 3 G of their paper and Fig. 2 F of the current study, the veins of L. kohkongensis are connected near the lamina margin, forming areoles in fertile fronds.

description: In this paper we develop a quantitative model of entrepreneurial activity (risk-taking) and consumer bankruptcy choices and use the model to study the effects of bankruptcy regulations on entrepreneurial activity, bankruptcy rate and welfare. We show that eliminating bankruptcy exemptions leads to a modest increase in the fraction of entrepreneurs, a large decrease in the overall bankruptcy rate and a significant welfare gain. In contrast, eliminating the whole consumer bankruptcy system leads to a large fall in the fraction of entrepreneurs and a substantial welfare loss. These two findings suggest that the consumer bankruptcy system is desirable but it must be well-designed with regard to bankruptcy asset exemptions. In particular, excessive bankruptcy exemptions can be counter-productive. Finally, we argue that entrepreneurial activity is important when studying different bankruptcy rules or regulations.

Ils montrent que l'abandon des dérogations prévues aux mesures de liquidation donne lieu à une légère hausse de la proportion d'entrepreneurs, à une chute notable du taux global de faillite et à un accroissement sensible du bien-être. À l'inverse, l'abolition de toute possibilité de recours à la faillite personnelle réduit beaucoup la proportion d'entrepreneurs et le bien-être. Il ressort de ces deux résultats que la procédure de faillite est un dispositif législatif utile, qui doit toutefois être bien conçu en ce qui concerne les biens exemptés de saisie. En effet, des dérogations trop généreuses peuvent être contre-productives. En conclusion, les auteurs soutiennent que l'étude des lois et règlements relatifs à la faillite doit tenir compte du rôle important de l'entrepreneuriat.

description: We investigate vortex-antivortex pair creation in a supersonically expanding and contracting quasi-2D Bose-Einstein condensate at zero temperature. For sufficiently large amplitude condensate oscillations, pair production provides the leading dissipation mechanism. The condensate oscillations decay in a nonexponential fashion, and the dissipation rate depends strongly on the oscillation amplitude. These features allow to distinguish the decay due to pair creation from other possible damping mechanisms. Experimental observation of the predicted oscillation behavior of the superfluid gas provides a direct confirmation of the hydrodynamical analogy of quantum electrodynamics and quantum vortex dynamics in two spatial dimensions.

title: Inflation Targeting and Price-Level-Path Targeting in the GEM: Some Open Economy Considerations

description: This paper compares the performance of simple inflation targeting (IT) and price-level path targeting (PLPT) rules to stabilize the macroeconomy, in response to a series of shocks, similar to those seen in Canada and the United States over the 1983 to 2004 period. The analysis is conducted in a two-country (Canada and the United States), two-sector (tradables and nontradables) version of the International Monetary Fund’s Global Economy Model (GEM). The authors conclude that PLPT is slightly preferred to IT for delivering macroeconomic stability, as it delivers a reduction in inflation and nominal interest rate volatility, at the expense of slightly higher output gap variability. When the analysis is restricted to the shocks that have been most important for explaining movements in Canada’s terms of trade over this period, PLPT is still preferred to IT. The authors also show that their results are sensitive to the interaction between the relative importance of the different types of macroeconomic shocks that hit the economy, and the extent to which price and wage setting is forward looking. Lastly, the authors demonstrate that the choice of monetary policy framework in the United States does not affect the relative merits of PLPT versus IT in Canada.
description: Les auteurs comparent la capacité de règles simples, comportant soit une cible d’inflation soit une cible de niveau des prix, à stabiliser l’économie dans son ensemble à la suite de chocs similaires à ceux survenus au Canada et aux États Unis entre 1983 et 2004. Pour ce faire, ils utilisent une version de GEM – le modèle de l’économie mondiale élaboré par le Fonds monétaire international – qui met en scène deux pays (le Canada et les États Unis)et deux secteurs (celui des biens échangeables et celui des biens non échangeables). Ils concluent que les régimes prenant pour cible le niveau des prix parviennent un peu mieux que les régimes de cibles d’inflation à stabiliser l’économie, atténuant la volatilité de l’inflation et des taux d’intérêt nominaux au prix d’une légère accentuation de la variabilité de l’écart de production. La conclusion reste la même lorsque l’analyse est limitée aux chocs jugés les plus déterminants pour l’évolution des termes de l’échange de 1983 à 2004. Les auteurs montrent également que leurs résultats sont sensibles à l’interaction entre l’importance relative des différents types de chocs macroéconomiques et le degré de prospectivité du processus d’établissement des prix et des salaires. Enfin, ils démontrent que le cadre adopté aux États-Unis en matière de politique monétaire n’influence pas les mérites relatifs des régimes ciblant le niveau des prix et des régimes de cibles d’inflation au Canada.

description: The 3 X 3 Majorana neutrino mass matrix is written as a sum of 3 terms, i.e. M_nu = M_A + M_B + M_C, where M_A is proportional to the identity matrix and M_B and M_C are invariant under different Z_3 transformations. This M_nu is very suitable for understanding atmospheric and solar neutrino oscillations, with sin^2 (2 theta_atm) and tan^2 (theta_sol) fixed at 1 and 0.5 respectively, in excellent agreement with present data. It has in fact been proposed before, but only as an ansatz. This paper uncovers its underlying symmetry, thus allowing a complete theory of leptons and quarks to be constructed.

title: Markups in Canada: Have They Changed and Why?
Creators: name: Leung, Danny
Publisher: name: Bank of Canada
Year: 2008

description: Many empirical studies have examined the cyclical nature of the markup ratio. Until recently, few have attempted to ascertain the changes in the markup over a longer time horizon. These changes are of no less interest in view of the posited effects of increasing import competition and lower inflation on the markup. This paper offers evidence on the evolution of the markups for the Canadian business sector and 33 disaggregate industries over the 1961–2004 period. It is found that the business sector markup has declined since the mid-1980s, and that import competition has made a statistically significant but small contribution to this decline.
description: De nombreuses études empiriques ont examiné la nature cyclique du taux de marge. Jusqu'à récemment, peu de chercheurs ont tenté de déterminer comment les marges variaient en longue période. Or, cette question n'est pas sans intérêt étant donné les effets présumés de la concurrence croissante des importations et de la baisse de l'inflation sur les marges. L'auteur présente des données sur l'évolution des marges au Canada entre 1961 et 2004, dans l'ensemble du secteur des entreprises et 33 branches d'activité différentes. Il constate que les marges régressent depuis le milieu des années 1980 dans le secteur des entreprises et qu'une part statistiquement significative mais modeste de ce recul est imputable à la concurrence des importations.
Theory of out-of-equilibrium electron and phonon dynamics in metals after ultrafast laser excitation

description: The out-of-equilibrium dynamics of electrons and phonons upon laser excitation are often described by the two-temperature model, which assumes that both subsystems are separately in thermal equilibrium. However, recent experiments show that this description is not sufficient to describe the out-of-equilibrium dynamics on ultrashort timescales. Here, we extend and apply a parameter-free microscopic out-of-equilibrium model to describe the ultrafast laser-induced system dynamics of archetypical metallic systems such as gold, aluminum, iron, nickel, and cobalt. We report strong deviations from the two-temperature model on the picosecond timescale for all the materials studied, even for those where the assumption of separate thermal equilibriums seemed less restrictive, like in gold. Furthermore, we demonstrate the importance of the phonon-mode dependent electron-phonon coupling for the relaxation process and reveal the significance of this channel in the lattice equilibration through an indirect coupling between phonons via the electronic system.

description: A novel method is developed for the synthesis of amine-substituted indole [3,4-b] azepine derivatives. In-situ chlorination, followed by nucleophilic substitution of 1,5-dichloro azepino[3,4-b] indole with respective amines yields the desired compounds. The reactivity of the azepinone ring toward chlorination reactions is intriguing and gives either rearranged or hydrolyzed products under aqueous work up conditions. In brominated azepinones, elimination is favored over nucleophilic substitution reaction. The synthesized compounds displayed in vitro cytotoxicity against human cancer cell lines.

description: No-Arbitrage option pricing models are used to derive ex ante expected price distributions. The performance of the method is assessed in the context of the calibration of the derived probability density functions, evaluated at the expiration date prices. It is found that the soybean and S&P 500 option-based probability assessments display some evidence of miscalibration very near to expiration and far from expiration.

A Method for Mapping the Temperature Profile of X-ray Clusters Through Radio Observations

Year: 2003

description: Many of the most luminous extragalactic radio sources are located at the centers of X-ray clusters, and so their radiation must be scattered by the surrounding hot gas. We show that radio observations of the highly-polarized scattered radiation (which depends on the electron density distribution) in combination with the thermal Sunyaev-Zeldovich effect (which measures the electron pressure distribution), can be used to determine the radial profile of the electron temperature within the host cluster. The sensitivity levels expected from current instruments will allow radio measurements of mass-weighted cluster temperature profiles to better than roughly 1 keV accuracy, as long as the central radio source is steady over several million years. Variable or beamed sources will leave observable signatures in the scattered emission. For clusters with a central point source brighter than about 1 mJy, the scattered polarization signal is stronger than competing effects due to the cosmic microwave background.

description: Abstract: The impact of deteriorating climatic conditions on variability in the archaeological record towards the Last Glacial Maximum (LGM) remains uncertain. Partly as a result of poor-quality data, previous studies on Upper Palaeolithic (UP) societies of North-Western Europe prior to the LGM have focused on techno-typological traditions and diversification to outline the diachronic processes through which assemblage composition changed. This study addresses the adaptive trade-offs brought about by the general climatic downturn towards the LGM in North-Western Europe, by investigating the impact of local climate and habitat characteristics on the behavioural variability that characterises Gravettian technological organisation compared to the previous Aurignacian, based on two assemblages from Walou Cave, Belgium. This site is one of the rare well-stratified sites in North-Western Europe with evidence for multiple occupation events accompanied by a fine-grained palaeoenvironmental record. We use a combination of analytical techniques (AMS, LA-ICP-MS and ZooMS) to evaluate questions about hunter-gatherer adaptations. Faunal remains at Walou Cave mirror the faunal diversity documented at numerous other Aurignacian and Gravettian sites in the broader European context, which is similar between both periods. The overall picture presented here, using multiple lines of evidence, is not entirely clear; nonetheless, the results suggest that Gravettian technologies are unlikely to solely be a product of heightened risk in relation to a significant reshuffling of food resources compared to the previous Aurignacian. Future research of the factors structuring assemblage variability prior to the LGM will have to assess whether Aurignacian and Gravettian technologies indeed offer no relative material advantage over one another, a phenomenon called ‘technological equivalence’.
