description: Growing interest in non-line-of-sight (NLoS) imaging, colloquially referred to as "seeing around corners", has led to the development of phasor-field ($\mathcal{P}$-field) imaging, wherein the field envelope of amplitude-modulated spatially-incoherent light is manipulated like an optical wave to directly probe a space that is otherwise shielded from view by diffuse scattering. Recently, we have established a paraxial theory for $\mathcal{P}$-field imaging in a transmissive geometry that is a proxy for three-bounce NLoS imaging [J. Dove and J. H. Shapiro, Opt. Express {\bf 27}(13) 18016--18037 (2019)]. Our theory, which relies on the Fresnel diffraction integral, introduces the two-frequency spatial Wigner distribution (TFSWD) to efficiently account for specularities and occlusions that may be present in the hidden space and cannot be characterized with $\mathcal{P}$-field formalism alone. However, because the paraxial assumption is likely violated in many, if not most, NLoS scenarios, in the present paper we overcome that limitation by deriving a nonparaxial propagation formula for the $\mathcal{P}$ field using the Rayleigh--Sommerfeld diffraction integral. We also propose a Rayleigh--Sommerfeld propagation formula for the TFSWD and provide a derivation that is valid under specific partial-coherence conditions. Finally, we report a pair of differential equations that characterize free-space TFSWD propagation without restriction.

Energy storage in a densely-built mediterranean city centre
Creators: name: Roberts, Sarah Marie
Publisher: name: University of British Columbia
Year: 2009

description: The complex, three-dimensional nature of an urban area and the challenges inherent in directly measuring urban energy storage flux (ΔQs) have led to this heat flux being an understudied component of the urban surface energy balance. The primary goal of this research is to compare the relative ability of several different methods to estimate the magnitude and temporal variation of ΔQs in an urban environment against those obtained as in observed energy balances. The investigation is based on results from a site in the center of Marseille, France. This locale provides an ideal environment for this study, because it has a warm, dry climate (hence sensible heat dominates) and massive urban development (hence a large thermal mass), so that heat storage is likely to be a significant part of the overall surface energy balance. Estimates of ΔQs obtained from tower-mounted instruments (the energy balance residual approach) are compared to results from a parameterization scheme (Objective Hysteresis Model, OHM), a localscale numerical model (Town Energy Balance, TEB), and a bulk heat transfer approach (Thermal Mass Scheme, TMS). Meteorological and urban construction data are used as inputs to the methods. Two-dimensional and three-dimensional formulations of the OHM do not sufficiently handle surface-atmosphere sensible heat exchanges in this highly urbanized and windy environment while TEB shows good agreement with the residual approach. TMS values are comparable to those from the other two methods but the laborious nature of the approach renders it impractical in such a complex setting. TEB's good performance at this site, as well as at other dry urban settings (central Mexico City and a light industrial site in Vancouver, British Columbia), suggest it possesses promise as a basis for further analyses and sensitivity tests designed to better understand the impacts of varying flow regimes, building geometry and materials on local-scale urban surface-atmosphere energy exchanges. Such an analysis was performed and the results reveal that the wind regime plays a dominant role in surface-atmosphere energy partitioning in this environment. Varying urban geometry and surface radiative properties also result in appreciable changes whereas alterations to surface thermal parameters generate the least impact.

description: The Muon Scattering Experiment at the Paul Scherrer Institut uses a mixed beam of electrons, muons, and pions, necessitating precise timing to identify the beam particles and reactions they cause. We describe the design and performance of three timing detectors using plastic scintillator read out with silicon photomultipliers that have been built for the experiment. The Beam Hodoscope, upstream of the scattering target, counts the beam flux and precisely times beam particles both to identify species and provide a starting time for time-of-flight measurements. The Beam Monitor, downstream of the scattering target, counts the unscattered beam flux, helps identify background in scattering events, and precisely times beam particles for time-of-flight measurements. The Beam Focus Monitor, mounted on the target ladder under the liquid hydrogen target inside the target vacuum chamber, is used in dedicated runs to sample the beam spot at three points near the target center, where the beam should be focused.

It implies either the failure of resonance saturation assumption or it suggests the existence of exotic baryon resonances in such a channel.

On the properties of contact binary stars

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A catalogue of light curve solutions of contact binary stars has been compiled. It contains the results of 159 light curve solutions. Properties of contact binary stars were studied by using the catalogue data. As it is well known since Lucy's (1968a,b) and Mochnacki's (1981) works, primary components transfer their own energy to the secondary star via the common envelope around the two stars. This transfer was parameterized by a transfer parameter (ratio of the observed and intrinsic luminosities of the primary star). We proved that this transfer parameter is a simple function of the mass and luminosity ratio. This newly found relation is valid for all systems except H type systems which have a different relation. We introduced a new type of contact binary stars: H subtype systems which have a large mass ratio ($q>0.72$). These systems show highly different behaviour on the luminosity ratio - transfer parameter diagram from other systems and according to our results the energy transfer rate is less efficient in them than in other type of contact binary stars. We also show that different types of contact binaries have well defined locations on the mass ratio - luminosity ratio diagram. All contact binary systems do not follow Lucy's relation ($L_2/L_1 = (M_2/M_1)^{0.92}$). No strict mass ratio - luminosity ratio relation of contact binary stars exists.

description: Shadow prices guide farmers' resource allocations, but for subsistence farmers growing traditional crops, shadow prices may bear little relationship with market prices. We econometrically estimate shadow prices of maize using data from a nationally representative survey of rural households in Mexico. Shadow prices are significantly higher than the market price for traditional but not improved maize varieties. They are particularly high in the indigenous areas of southern and southeastern Mexico, indicating large de facto incentives to maintain traditional maize there.

description: A catastrophe (CAT) bond is designed for peanut production as a means of transferring natural disaster risks from insurance purveyors to the global capital market. The CAT bond so designed is priced using state-level historical yields for peanut production in the southern part of the United States in the State of Georgia. The index triggering the CAT bond contract was based on percent deviation from state average yield. The principal finding of the study is that it appears feasible for crop insurance purveyors to issue insurance-linked securities. CAT bonds can reduce the variance of the loss ratio when issued optimally with regard to the number of bonds and contract specifications. CAT bonds could therefore be used in hedging catastrophic risk effectively in peanut production given that crop insurance purveyors normally seek to minimize the variance of the loss ratio. CAT bonds were found to be feasible as hedging instruments even in the range of normal losses commonly covered by crop insurance and reinsurance.

description: We study a service market with two firms: one that provides regular and another that provides premium services. Customers are delay sensitive and heterogeneous in evaluating the service level. We study two competition games that differ in segmentation-marketing strategies. One is the size-based competition in which firms compete on the segment size dimension, and the other is the value-based competition in which firms compete on the segment target (regarding customer valuation) dimension. For both games, the Nash equilibrium always exists, and the (Pareto dominant) equilibrium is unique. Interestingly, the premium service provider's effective arrival rate can be increasing in its competitor's service rate in the value-based game. Moreover, we capture the conditions for the equilibrium market as either a monopoly or a duopoly and show that size-based competition helps sustain service variety. We also show that the prices are reduced in the value-based game; the premium (regular) service provider serves more (fewer) customers in the value-based game than in the size-based game. Our results show that value-based competition is more intensive in the sense that the number of customers who are served, customer surplus and social welfare are higher, while the total revenue of two firms is lower in the value-based competition than in the size-based competition.

description: Grallaria rufocinerea Sclater & Salvin, 1879
Bicolored Antpitta
 Includes populations designated rufocinerea and romeroana in the analysis.
 Diagnosis. Differs from all other species in the complex in having gray underparts that contrast sharply with its rufous head, throat, and upperparts. Its long song (Fig. 5), a nearly evenly paced series of similar notes, distinguishes G. rufocinerea from all other taxa in the complex, except G. rufula sensu stricto. Its single-noted short song distinguishes G. rufocinerea from G. rufula sensu stricto and from all other taxa except G. centralis and G. ayacuchensis; it is distinguished from the latter two species by greater duration and by note shape, which is flat or very slightly upslurred, as contrasted with G. centralis (inverted U) and G. ayacuchensis (downslurred).
 Distribution. Central Andes from central Antioquia, Colombia, south to the upper Magdalena Valley and along the eastern slope from Cauca, Colombia, to Sucumbíos, Ecuador, 1950–3250 m.
 Plumage. The dark gray underparts of G. rufocinerea are unique in the G. rufula complex (specimen photographs App. 6, Figs. A17 and A 18).
 Remarks. Species status is supported by vocal as well as plumage characters. Reexamination of the taxonomic status of romeroana (Hernández & Rodríguez, 1979) requires more vocal data, especially recordings of its long song, as well as additional plumage comparisons with the nominate. Pending that review, we recommend its maintenance as a subspecies of rufocinerea based on the original description. The geographic range of G. rufocinerea is sympatric/parapatric with that of northern populations of G. saturata (see below).
 PRINCIPAL CLADE C. This clade includes rufula 2 of the Central Andes of Colombia with an outlying population (rufula 2a) on the western slope of the Eastern Andes, rufula 4 in the Western Andes of Colombia, and rufula 5 of the Andes from southern Colombia to extreme northern Peru. The structure of their short songs is distinct from those of all other populations.

description: In 2005 the Hungarian Exise Tax Act was amended regarding the sale of biofuels. The amendment stipulated that from July 1, 2007 fuels with a 4.4 volume percentage bioethanol content will be sold in Hungary. It equally stipulated that from January 1, 2008 fuels with a 4.4 volume percentage biodiesel content will also be sold. Hungary’s stated 2010 biofuel objective is 5.75%, which is calculated in relation to energy content. Blending requirements for this transition are 144 thousand tonnes of bioethanol (or 106 thousand tonnes of ETBE, due to its higher energy content) and 183 thousand tonnes of biodiesel. Hungary’s planned biofuel production capacities are approximately 3 million tonnes of bioethanol and 400 thousand tonnes of biodiesel, which seems farfetched both from a raw material and market point of view. Generous long-term estimates predict bioethanol production will utilise 40-50% of Hungary’s maize production, (3-4 million tonnes) and 1.2 million tonnes of wheat. And from this would come 1.4-1.7 million tonnes of bioethanol. Hungarian rape and sunflower seed total approximately 850 thousand tonnes, and from this approximately 255 thousand tonnes of biodiesel could be produced. Hungarian domestic demand does not require this much product, and these quantities would entail major exports, especially for bioethanol (1.2-1.5 M tonnes).

description: Routing optimization is a relevant problem in many contexts. Solving directly this type of optimization problem is often computationally unfeasible. Recent studies suggest that one can instead turn this problem into one of solving a dynamical system of equations, which can instead be solved efficiently using numerical methods. This results in enabling the acquisition of optimal network topologies from a variety of routing problems. However, the actual extraction of the solution in terms of a final network topology relies on numerical details which can prevent an accurate investigation of their topological properties. In this context, theoretical results are fully accessible only to an expert audience and ready-to-use implementations for non-experts are rarely available or insufficiently documented. In particular, in this framework, final graph acquisition is a challenging problem in-and-of-itself. Here we introduce a method to extract networks topologies from dynamical equations related to routing optimization under various parameters' settings. Our method is made of three steps: first, it extracts an optimal trajectory by solving a dynamical system, then it pre-extracts a network and finally, it filters out potential redundancies. Remarkably, we propose a principled model to address the filtering in the last step, and give a quantitative interpretation in terms of a transport-related cost function. This principled filtering can be applied to more general problems such as network extraction from images, thus going beyond the scenarios envisioned in the first step. Overall, this novel algorithm allows practitioners to easily extract optimal network topologies by combining basic tools from numerical methods, optimization and network theory. Thus, we provide an alternative to manual graph extraction which allows a grounded extraction from a large variety of optimal topologies.

description: The theory behind the electrical switching of antiferromagnets is premised on the existence of a well defined broken symmetry state that can be rotated to encode information. A spin glass is in many ways the antithesis of this state, characterized by an ergodic landscape of nearly degenerate magnetic configurations, choosing to freeze into a distribution of these in a manner that is seemingly bereft of information. In this study, we show that the coexistence of spin glass and antiferromagnetic order allows a novel mechanism to facilitate the switching of the antiferromagnet Fe$_{1/3+δ}$NbS$_2$, which is rooted in the electrically-stimulated collective winding of the spin glass. The local texture of the spin glass opens an anisotropic channel of interaction that can be used to rotate the equilibrium orientation of the antiferromagnetic state. The use of a spin glass' collective dynamics to electrically manipulate antiferromagnetic spin textures has never been applied before, opening the field of antiferromagnetic spintronics to many more material platforms with complex magnetic textures.

description: The problem of the cosmic coincidence is a longstanding puzzle. This conundrum may be solved by introducing a coupling between the two dark sectors. In this Letter, we study a coupled quintessence scenario in which the scalar field evolves in a power law potential and the mass of dark matter particles depends on a power law function of $ϕ$. It is shown that this scenario has a stable attractor solution and can thus provide a natural solution to the cosmic coincidence problem.

description: The longitudinal and transverse components of the cross section for the $e p\to e^\prime p ρ^0$ reaction were measured in Hall B at Jefferson Laboratory using the CLAS detector. The data were taken with a 4.247 GeV electron beam and were analyzed in a range of $x_B$ from 0.2 to 0.6 and of $Q^2$ from 1.5 to 3.0 GeV$^2$. The data are compared to a Regge model based on effective hadronic degrees of freedom and to a calculation based on Generalized Parton Distributions. It is found that the transverse part of the cross section is well described by the former approach while the longitudinal part can be reproduced by the latter.

Grallaria cajamarcae

description: Grallaria cajamarcae (Chapman, 1927), subspecies elevated to species
Cajamarca Antpitta
 Includes population designated cajamarcae in the analysis.
 Diagnosis. Upperparts and throat reddish yellow-brown; breast paler, posteriorly with pale feather edges grading to a mix of buff and white on the belly and undertail coverts; pale eye-ring. Underparts of cajamarcae are the palest of all populations and separable in blind tests from neighboring populations. Short song is a slow-paced (~2 notes/sec), short (typically 5–6 notes) series of similarly shaped notes delivered at about the same frequency, which is a unique vocalization in the complex (Fig. 8). Notes may be slightly downslurred or flat and often lengthen and then shorten. Long song (Fig. 8) is a trill, similar to others in the complex but distinct in that peaks of the final notes rise in frequency, a character otherwise found only in long songs of G. cochabambae. The long song of G. cochabambae differs from that of G. cajamarcae in that peaks of initial notes decline in frequency, whereas peaks of initial notes of G. cajamarcae are constant in frequency.
 Distribution. Endemic to Peru; in Andes of Piura, Cajamarca, and Lambayeque west of the Río Huancabamba and the upper Río Marañón, 2850–3400 m.
 Plumage. Overall plumage of upperparts, including rectrices, remiges (primaries edged paler), crown and auriculars, dark reddish yellow-brown (7.5YR 4/4–5/4) with pale eye-ring and shading to color of underparts in malar area. Overall plumage of underparts light reddish yellow-brown (7.5YR 7/10–6/10) with pale feather edgings, becoming pale yellowish-buff (2.5Y 8/4) mixed with whitish in center of belly and undertail coverts; flanks dark yellowish-brown (10YR 4/4) (specimen photographs App. 6, Figs. A22 and A33).
 Etymology. The English name reflects the scientific name and the geographic range of this species, which is primarily confined to Cajamarca, Peru. The name was also used by Krabbe et al. (2019).
 Remarks. Grallaria cajamarcae is specifically distinct based on vocal characters, supported by plumage characters and mtDNA genetic distance of>5.5% with all other populations.

This is defined as innovation developed in a short period of time in a state of emergency with the hope of protecting people and saving lives (Gutierrez, Castillo, and Montiel 2020). Following our initial call, things have moved very quickly, and we continue to track how innovation has mushroomed. We witnessed business responses take off and then evolve into a variety of initiatives.

description: Mobility data at EU scale can help understand the dynamics of the pandemic and possibly limit the impact of future waves. Still, since a reliable and consistent method to measure the evolution of contagion at international level is missing, a systematic analysis of the relationship between human mobility and virus spread has never been conducted. A notable exceptions are France and Italy, for which data on excess deaths, an indirect indicator which is generally considered to be less affected by national and regional assumptions, are available at department and municipality level, respectively. Using this information together with anonymised and aggregated mobile data, this study shows that mobility alone can explain up to 92% of the initial spread in these two EU countries, while it has a slow decay effect after lockdown measures, meaning that mobility restrictions seem to have effectively contribute to save lives. It also emerges that internal mobility is more important than mobility across provinces and that the typical lagged positive effect of reduced human mobility on reducing excess deaths is around 14-20 days. An analogous analysis relative to Spain, for which an IgG SARS-Cov-2 antibody screening study at province level is used instead of excess deaths statistics, confirms the findings. The same approach adopted in this study can be easily extended to other European countries, as soon as reliable data on the spreading of the virus at a suitable level of granularity will be available. Looking at past data, relative to the initial phase of the outbreak in EU Member States, this study shows in which extent the spreading of the virus and human mobility are connected.

description: Carried out in 2006, this study presents the results of a questionnaire survey covering 110 organic farms. For these farms the study shows the production structure, the parameters governing the conversion from conventional production to organic farming, and the factors motivating this conversion. Among aspects surveyed are changes in cost-output/sales price and respondents’ opinions regarding selling organic products. Also discussed are respondents’ subsequent success stories. Included in this paper are farmers’ future expectations relating to demand and prices. The results obtained are contrasted with those published in domestic and international professional literature.

description: A facile procedure of doping copper species into CeO2 lattices was reported here to prevent ceria from deactivation and to offer additional active sites for H2S selective oxidation. Among the prepared catalysts, the porous 10Cu/Ce nanorods with well-defined (100) and (110) reactive planes displays excellent catalytic performance, exhibiting H2S conversion and sulfur selectivity of 100% at 220 °C, which is higher than those of the most reported Ce-based catalysts. More importantly, the electron transfer from Cu+ to Ce4+ suppresses the transfer of electron from SO2 to Ce4+, leading to inhabitation of SO2 oxidation to surface SO4 which could deactivate catalyst. Overall, the results of systematic experimental and theoretical studies prove that the copper doping effectively promotes the formation of oxygen vacancies and resistance against SO2 poisoning. Furthermore, through in situ diffuse reflection infrared Fourier transform spectroscopy (DRIFTS) investigation and density functional theory (DFT) calculations, the reaction intermediates in H2S selective oxidation and mechanism of SO2 resistance over the Cu-doped CeO2 catalysts are revealed.

description: This paper uses a finite mixture logit (FML) model to investigate the heterogeneity of preferences of beach users for water quality at beaches in Southern California. The results are compared with conventional approaches based conditional logit (CL) and random parameters logit (RPL). The FML approach captures variation in preferences by modeling individual recreator choices using a mixture of several distinct preference groups, where group membership is a function of individual characteristic and seasonal variables. The FML parameter estimates are used to calculate welfare measures for improvements in beach quality through a reduction of water pollution. The FML segment specific welfare measures bound the traditional CL and RPL mean welfare estimates, and have the advantage of highlighting the distribution of the population sample’s preferences. Analysis of beach recreation site choice data indicates the existence of four representative preference groups within the survey respondent sample. As a result, willingness to pay measures for improvements in water quality and other beach site attribute changes can be weighted across individuals to calculate the distribution of individual welfare measures. One group of recreators is characterized as people who go to the beach and engage in water recreation with children. An interesting finding is that this group has a lower mean WTP for improving water quality than groups who go without children. This may well be an example of cognitive dissonance: parents find they go to the beach more often than others who don’t have children, since that keeps the children occupied and happy, and they adapt their perception of the water quality to be consistent with their behavior. Previous environmental and resource economic applications of the FML have been limited to applications with small choice sets (6) and group membership variables (4). This paper extends the FML model through the estimation of a large (51) choice set with 9 membership variables. This application is the first to incorporate seasonal variables into the group membership function to capture seasonal heterogeneity. Estimated welfare changes are calculated using the compensating variation measure for several hypothetical beach closure and water quality degradation scenarios. Estimation results indicate that the FML welfare estimates differ from those calculated using the traditional logit or RPL models. The FML model sheds light onto which subsets of beach recreators are likely to be impacted by different scenarios of resource change.

description: We present infrared luminosity functions and dust mass functions for the EAGLE cosmological simulation, based on synthetic multi-wavelength observations generated with the SKIRT radiative transfer code. In the local Universe, we reproduce the observed infrared luminosity and dust mass functions very well. Some minor discrepancies are encountered, mainly in the high luminosity regime, where the EAGLE-SKIRT luminosity functions mildly but systematically underestimate the observed ones. The agreement between the EAGLE-SKIRT infrared luminosity functions and the observed ones gradually worsens with increasing lookback time. Fitting modified Schechter functions to the EAGLE-SKIRT luminosity and dust mass functions at different redshifts up to $z=1$, we find that the evolution is compatible with pure luminosity/mass evolution. The evolution is relatively mild: within this redshift range, we find an evolution of $L_{\star,250}\propto(1+z)^{1.68}$, $L_{\star,\text{TIR}}\propto(1+z)^{2.51}$ and $M_{\star,\text{dust}}\propto(1+z)^{0.83}$ for the characteristic luminosity/mass. For the luminosity/mass density we find $\varepsilon_{250}\propto(1+z)^{1.62}$, $\varepsilon_{\text{TIR}}\propto(1+z)^{2.35}$ and $ρ_{\text{dust}}\propto(1+z)^{0.80}$, respectively. The mild evolution of the dust mass density is in relatively good agreement with observations, but the slow evolution of the infrared luminosity underestimates the observed luminosity evolution significantly. We argue that these differences can be attributed to increasing limitations in the radiative transfer treatment due to increasingly poorer resolution, combined with a slower than observed evolution of the SFR density in the EAGLE simulation and the lack of AGN emission in our EAGLE-SKIRT post-processing recipe.

description: The availability of neutron spallation-source instruments that provide total scattering powder diffraction has led to an increased application of real-space structure analysis using the pair distribution function. Currently, the analytical treatment of finite size effects within pair distribution refinement procedures is limited. To that end, an envelope function is derived which transforms the pair distribution function of an infinite solid into that of a spherical particle with the same crystal structure. Distributions of particle sizes are then considered, and the associated envelope function is used to predict the particle size distribution of an experimental sample of gold nanoparticles from its pair distribution function alone. Finally, complementing the wealth of existing diffraction analysis, the peak broadening for the structure factor of spherical particles, expressed as a convolution derived from the envelope functions, is calculated exactly for all particle size distributions considered, and peak maxima, offsets, and asymmetries are discussed.

description: Firms spend billions of dollars each year advertising consumer products in order to influence demand. Much of these outlays are on the creative design of advertising content. Creative content often uses nuances of presentation and framing that have large effects on consumer decision making in laboratory studies. But there is little field evidence on the effect of advertising content as it compares in magnitude to the effect of price. We analyze a direct mail field experiment in South Africa implemented by a consumer lender that randomized creative content and loan price simultaneously. We find that content has significant effects on demand. There is also some evidence that the magnitude of content sensitivity is large relative to price sensitivity. However, it was difficult to predict which particular types of content would significantly impact demand. This fits with a central premise of psychology— context matters— and highlights the importance of testing the robustness of laboratory findings in the field.

description: In order to analyze the impact of COVID-19 on people's lives, activities and the natural environment, this paper investigates the spatial and temporal characteristics of Night Time Light (NTL) radiance and Air Quality Index (AQI) before and during the pandemic in mainland China. Our results show that the monthly average NTL brightness is much lower during the quarantine period than before. This study categorizes NTL into three classes: residential area, transportation and public facilities and commercial centers, with NTL radiance ranges of 5-20, 20-40 and greater than 40 nW/(cm*cm*sr), respectively. We found that the Number Of Pixels (NOP) with NTL detection increased in the residential area and decreased in the commercial centers for most of the provinces after the shutdown, while transportation and public facilities generally stayed the same. More specifically, we examined these factors in Wuhan, where the first confirmed cases were reported, and where the earliest quarantine measures were taken. Observations and analysis of pixels associated with commercial centers were observed to have lower NTL radiance values, indicating a dimming behavior, while residential area pixels recorded increased levels of brightness, after the beginning of the lockdown. The study also discovered a significant decreasing trend in the daily average AQI for the whole country, with cleaner air in most provinces during February and March, compared to January 2020. In conclusion, the outbreak and spread of COVID-19 has had a crucial impact on people's daily lives and activity ranges through the increased implementation of lockdown and quarantine policies. On the other hand, the air quality of China has improved with the reduction of non-essential industries and motor vehicle usage.

description: The in-plane $ρ_{ab}(H,T)$ and the out-of-plane $ρ_c(H,T)$ magneto-transport in magnetic fields up to 28 T has been investigated in high quality non-superconducting (down to 20 mK) La-free Bi$_{2+x}$Sr$_{2-x}$CuO$_{6+δ}$ single crystal. By measuring the angular dependence of the in-plane and out-of-plane magnetoresistivities at temperatures from 1 K down to 30 mK, we present evidence for the presence of vortex-like excitations in a non-superconducting cuprate in the insulating state. Such excitations have previously been observed by the detection of a Nernst signal in superconducting cuprates at $T>T_c$ in magnetic fields.

description: We show how the resummation of large logarithms can be incorporated into the method of effective charges. As an example, we apply this approach to the event shape variables thrust and heavy jet mass in e+e- annihilation. We find that, although the resummation creates problems with the behaviour of the efective charge in the 2-jet limit, smaller power corrections are required to fit the data compared to the standard approach. In addition, increasing the logarithmic accuracy reduces the size of the power corrections further. We also consider ``predicting'' the sub-leading logarithms in the MSbar scheme, obtaining surprisingly good results for the first few NLL terms.
