description: В работе впервые публикуются результаты раскопок скифского кургана 13 группы «Водовод», изученного в 2018 г. у с. Глиное Слободзейского района на левобережье Нижнего Днестра. Научные данные, полученные при исследовании этого кургана, позволяют обратить особое внимание на некоторые элементы погребального обряда — устройство ритуальных ям, захоронения собак, необычное размещение наконечников стрел в захоронении, устройство земляных «ложа» и «подушки». В погребениях найдены предметы вооружения (наконечники стрел, наконечники и втоки копий), орудия труда (ножи), посуда (деревянная миска) и украшения (ожерелье из стеклянных бусин). На основании бронзовых наконечников стрел курган 13 группы «Водовод» датируется второй половиной IV в. до н.э.

description: The effects of rail deregulation on feed transportation in the Northeast are examined through construction of a spatial equilibrium model of the Northeastern feed industry. Short-run and long-run effects of deregulation are analyzed through incorporation of rail rate structures for 1981 and 1984, respectively, into model simulations and comparison with pre-deregulation base year results (1980). The results show that the Northeast feed economy has generally benefited from rail deregulation which has led to lower transportation costs, lower feed costs and an enhanced competitive position relative to the Southeastern U.S.

description: The Per2M(mnt)2 class of organic conductors exhibit a charge density wave (CDW) ground state below about 12 K, which may be suppressed in magnetic fields of order 20 to 30 T. However, for both cases of counter ion M(mnt)2 species studied (M = Au (zero spin) and M = Pt (spin 1/2)), new high field ground states evolve for further increases in magnetic field. We report recent investigations where thermopower, Hall effect, high pressure and additional transport measurements have been carried out to explore these new high field phases.

Эти детали ранее не замечались коллегами. Попытки неприменно связать такие композиции с одним из немногих текстов, известных у греческих авторов, кажутся бесперспективными. Сюжет с коллективной охотой и дополнившие его сакральные сцены анализируются на пластине-стленгиде головного убора из Песочина. Единственное божество на скифском оружии — человек-петух с сопровождающими его драконами из Соболевой Могилы — исходно связан с искусством древней Маргианы (Маргуш), затем — Хорезма.

description: The existing solid electrolytes for lithium ion batteries suffer from low total ionic conductivity, which restricts its usefulness for the lithium-ion battery technology. Among them, the NASICON-based materials, such as Li1.3Al0.3Ti1.7(PO4)3 (LATP) exhibit low total ionic conductivity due to highly resistant grain boundary phase. One of the possible approaches to efficiently enhance their total ionic conductivity is the formation of a composite material. Herein, the Li2.9B0.9S0.1O3.1 glass, called LBSO hereafter, was chosen as an additive material to improve the ionic properties of the ceramic Li1.3Al0.3Ti1.7(PO4)3 base material. The properties of this Li1.3Al0.3Ti1.7(PO4)3-xLi2.9B0.9S0.1O3.1 (0 < x < 0.3) system have been studied by means of high temperature X-ray diffractometry (HTXRD), 7Li, 11B, 27Al and 31P magic angle spinning nuclear magnetic resonance spectroscopy (MAS NMR), thermogravimetry (TG), scanning electron microscopy (SEM), impedance spectroscopy (IS) and density methods. We show here that the introduction of the foreign LBSO phase enhances their electric properties. This study reveals several interesting correlations between the apparent density, the microstructure, the composition, the sintering temperature and the ionic conductivity. Moreover, the electrical properties of the composites will be discussed in the terms of the brick-layer model (BLM). The highest value of σtot = 1.5 x 10-4 Scm-1 has been obtained for LATP-0.1LBSO material sintered at 800°C.

description: We present an ab initio study of the structural and electronic properties of styrene molecules adsorbed on the dimerized Si(100) surface at different coverages, ranging from the single-molecule to the full monolayer. The adsorption mechanism primarily involves the vinyl group via a [2+2] cycloaddition process that leads to the formation of covalent Si-C bonds and a local surface derelaxation, while it leaves the phenyl group almost unperturbed. The investigation of the functionalized surface as a function of the coverage (e.g. 0.5 -- 1 ML) and of the substrate reconstruction reveals two major effects. The first results from Si dimer-vinyl interaction and concerns the controlled variation of the energy bandgap of the interface. The second is associated to phenyl-phenyl interactions, which gives rise to a regular pattern of electronic wires at surface, stemming from the pi-pi coupling. These findings suggest a rationale for tailoring the surface nano-patterning of the surface, in a controlled way.

description: We prove a localization theorem for continuous ergodic Schrödinger operators $ H_ω:= H_0 + V_ω$, where the random potential $ V_ω$ is a nonnegative Anderson-type perturbation of the periodic operator $ H_0$. We consider a lower spectral band edge of $ σ(H_0) $, say $ E= 0 $, at a gap which is preserved by the perturbation $ V_ω$. Assuming that all Floquet eigenvalues of $ H_0$, which reach the spectral edge 0 as a minimum, have there a positive definite Hessian, we conclude that there exists an interval $ I $ containing 0 such that $ H_ω$ has only pure point spectrum in $ I $ for almost all $ ω$.

description: We use an existing model of the $ΛΛN - ΞNN$ three-body system based in two-body separable interactions to study the $(I,J^P)=(1/2,1/2^+)$ three-body channel. For the $ΛΛ$, $ΞN$, and $ΛΛ- ΞN$ amplitudes we have constructed separable potentials based on the most recent results of the HAL QCD Collaboration. They are characterized by the existence of a resonance just below or above the $ΞN$ threshold in the so-called $H$-dibaryon channel, $(i,j^p)=(0,0^+)$. A three-body resonance appears {2.3} MeV above the $Ξd$ threshold. We show that if the $ΛΛ- ΞN$ $H$-dibaryon channel is not considered, the $ΛΛN - ΞNN$ $S$ wave resonance disappears. Thus, the possible existence of a $ΛΛN - ΞNN$ resonance would be sensitive to the $ΛΛ- ΞN$ interaction. The existence or nonexistence of this resonance could be evidenced by measuring, for example, the $Ξd$ cross section.

description: In this paper we estimate the price and income elasticities for five sweet spreads using a two-stage budgeting procedure. The first stage modeled the consumer's budget decision as a Tobit model, where total sweet spread expenditures are based on income and demographic variables. The second stage, including only those households with nonzero first stage expenditures, was treated as a standard consumer allocation problem using the AIDS model. To incorporate population demographics, the AIDS model was expanded by specifying the constant term as a linear function of demographic variables. The coefficients for the prices and expenditures are highly significant and demand is elastic for all five goods. The most significant demographic effects are due to household size, and female food shopper. The theoretical restrictions of homogeneity and symmetry were tested and rejected for the complete system.

description: We present the design and the circuit details of a high-sensitivity microwave vector detection system, which is aiming for studying the low-dimensional electron system embedded in the slots of a coplanar waveguide at low temperatures. The coplanar waveguide sample is placed inside a phase-locked loop; the phase change of the sample may cause a corresponding change in the operation frequency, which can be measured precisely. We also employ a double-pulse modulation on the microwave signals, which comprises a fast pulse modulation for gated averaging and a slow pulse modulation for lock-in detection. In measurements on real samples at low temperatures, this system provides much better resolutions in both amplitude and phase than most of the conventional vector analyzers at power levels below -65 dBm.

description: The demand for electricity in the residential sector is estimated to have become less elastic for the recent period of rising real prices as compared to earlier periods of stable or falling real price. Several possible reasons for this are investigated and we conclude that demand appears to be asymmetric with respect to price in both the short and long run. We then examine whether or not this is an important factor for forecast accuracy and public policy.

description: In some physical and biological swarms, agents effectively move and interact along curved surfaces. The associated constraints and symmetries can affect collective-motion patterns, but little is known about pattern stability in the presence of surface curvature. To make progress, we construct a general model for self-propelled swarms moving on surfaces using Lagrangian mechanics. We find that the combination of self-propulsion, friction, mutual attraction, and surface curvature produce milling patterns where each agent in a swarm oscillates on a limit cycle, with different agents splayed along the cycle such that the swarm's center-of-mass remains stationary. In general, such patterns loose stability when mutual attraction is insufficient to overcome the constraint of curvature, and we uncover two broad classes of stationary milling-state bifurcations. In the first, a spatially periodic mode undergoes a Hopf bifurcation as curvature is increased which results in unstable spatiotemporal oscillations. This generic bifurcation is analyzed for the sphere and demonstrated numerically for several surfaces. In the second, a saddle-node-of-periodic-orbits occurs in which stable and unstable milling states collide and annihilate. The latter is analyzed for milling states on cylindrical surfaces. Our results contribute to the general understanding of swarm pattern-formation and stability in the presence of surface curvature, and may aid in designing robotic swarms that can be controlled to move over complex surfaces.

description: Linear programming model is used to investigate the economic feasibility of utilizing stony lands for crop production in South-Western Quebec where stoniness is the major constraint. Results for the representative farms indicate that income variations are due to economies of size, differences in crop yields (experimental or farm level) and type of reclamation method used. The market values for stony lands (determined by regression technique) are higher compared with the productive values. Analysis also indicates that crop production is feasible within the parameters defined and that it is more economical to develop unutilized stony land rather than purchase prime agricultural land at current market prices. Parametric programming procedures indicate that the solutions are more sensitive to crop yields and prices than reclamation costs.

description: В 2014 г. при исследовании некрополя античного Паниардиса на территории г. Азова в женском погребении была обнаружена уникальная находка — терракотовая статуэтка, изображающая юношу у гермы. Терракоты с подобным сюжетом изготавливались во II в. до н.э. — I в. н.э. на территории Боспора. Местные коропласты вдохновлялись высокохудожественными произведениями танагрских мастеров IV—III вв. до н.э., которые, в свою очередь, подражали статуям известных скульпторов классического периода. При атрибуции находки авторы обращались к сюжетам на античных расписных вазах и эпическим и философским произведениям. В основе сюжета терракоты прослеживается символика дионисийско-орфического круга верований. Данная находка свидетельствует о высокой степени эллинизации верхушки местного общества, почитающего Диониса хтонического. Возможно, помещение ее в ногах усопшей отражало определенные религиозные верования местных жителей: она могла служить проводником в потусторонний мир.
Spectral control of total internal reflection for novel information displays
Creators: name: Mossman, Michele Ann
Publisher: name: University of British Columbia
Year: 2009

description: A new method for creating a reflective image device has been devised based on total internal reflection (TIR). This technique has the potential to yield a brighter, highercontrast image than those of current reflective displays by incorporating polymeric micro-prismatic sheets that reflect by means of TIR. High surface reflectance is achieved by efficiently redirecting ambient light toward the viewer, and an image is generated by controllably preventing, or "frustrating", the reflection in selected regions through absorption of light in the very thin evanescent wave region near the TIR interface. The transition between the reflective and absorptive state requires a motion of less than a micron of the absorber, and therefore it can occur quickly and efficiently. A fundamental problem in this approach - interfacial adhesion - was ameliorated through the use of liquid phase backing material, instead of gas. However, this complicated the optical requirements by substantially reducing the refractive index ratio at the TIR interface. To maintain TIR over an acceptable angular range, a low refractive index perfluorinated hydrocarbon was identified as an ideal liquid, and an optical configuration was devised to enhance the effective refractive index ratio at the interface. Detailed Monte Carlo ray tracing verified that high reflectance and a high contrast ratio are achievable with these designs over a useful range of viewing directions. Electrophoresis of pigment particles in a perfluorinated hydrocarbon has been shown to be a practical method for modulating TIR. The observed photometric performance is consistent with a numerical model developed to describe the interaction of an incident light ray with a density distribution of particles near the interface. Colour pigment suspensions have yielded, for the first time, spectrally selective control of TIR, which requires the particles to be essentially non-scattering but selectively absorptive. The results presented here demonstrate the feasibility of this TIR-based approach in practical reflective image device applications, and are suggestive that further development work in this area is warranted.

description: Some of the implications of ethical preferences for traditional welfare analyses of existence values are discussed in this paper and illustrated with a lexicographic model for preference structures. Although willingness-to-pay and willingness-to-sell are well-defined, their connection with Hicksian surpluses is lost when a person is motivated by an ethical commitment to others welfare. Researchers need to expand contingent valuation methods to collect information on underlying motives and types of preferences in order to identify respondents who fit the neoclassical model of egoistic man.

description: In the framework of nuclear physics and at nuclear physics facilities a large number of different experiments can be performed which render the possibility to investigate fundamental symmetries and interactions in nature. In particular, the precise measurements of properties of fundamental fermions, searches for new interactions in $β$-decays, and violations of discrete symmetries have a robust discovery potential for physics beyond standard theory. Precise measurements of fundamental constants can be carried out as well. Low energy experiments allow probing of New Physics models at mass scales far beyond the reach of present accelerators or such planned for the future in the domain of high energy physics and at which predicted new particles could be produced directly.

На данный момент в научной среде существует устоявшееся мнение о том, что такие изделия не использовались в качестве браслетов, а являлись исключительно амулетами. Главным аргументом для такого вывода считается отсутствие примеров фиксации данных изделий на руках погребённых. Для ревизии такого суждения были рассмотрены архивные источники и публикации комплексов с такими браслетами, изучены планы и описания погребений. В результате исследования было наглядно показано, что случаи нахождения браслетов с шишечками на руках погребённых известны, что позволяет интерпретировать их именно в качестве браслетов.

description: Over-application of manure on cropland can cause water quality degradation. This paper reports a modeling approach for assessing tradeoffs among manure storage and handling systems as they relate to the nutrient loadings in cropland runoff, including nitrate losses to groundwater. The CREAMS simulation model provided estimates of nutrient losses. A linear optimization model was used to determine the income-nutrient loss tradeoffs. Six-month storage was profitable for farmers with average-size dairy herds, but compared to daily spreading caused increased nitrate leaching through the soil to groundwater resources. Twelve-month storage systems decreased farm profitability while decreasing the total nitrogen losses from farm fields.

description: We report the de Haas-van Alphen (dHvA) effect and magnetoresistance in the filled-skutterudite superconductor LaRu4P12, which is a reference material of PrRu4P12 that exhibits a metal-insulator (M-I) transition at T_MI~60 K. The observed dHvA branches for the main Fermi surface (FS) are well explained by the band-structure calculation, using the full potential linearized augmented-plane-wave method with the local-density approximation, suggesting a nesting instability with q =(1,0,0) in the main multiply connected FS as expected also in PrRu4P12. Observed cyclotron effective masses of (2.6-11.8)m_0, which are roughly twice the calculated masses, indicate the large mass enhancement even in the La-skutterudites. Comparing the FS between LaRu4P12 and PrRu4P12, an essential role of c-f hybridization cooperating with the FS nesting in driving the the M-I transition in PrRu4P12 has been clarified.

Впервые удалось выявить и изучить фрагменты этой столовой посуды, датируемой XVII—XVIII вв., которые хранятся в фондовых коллекциях Археологического музея-заповедника «Танаис» и Азовского историко-археологического и палеонтологического музея-заповедника. За 50 лет работы на данных археологических памятниках было обнаружено 97 фрагм. глазурованной глиняной посуды с мраморовидным декором (18 фрагм. — в крепости Сед-Ислам, 79 фрагм. — в крепости Азак). Среди них преобладают остатки сосудов открытой формы — тарелок и чаш (90,8%). Находки фрагментов посуды закрытой формы (кувшинов) весьма редки (6,2%). В Азаке встречены 3 крышки от кувшинов (3%). Основная часть данной посуды, по мнению автора, является импортом из Анатолии и с побережья Мраморного моря. Визуальное сходство глиняного теста некоторых фрагментов «мраморовидной» керамики, обнаруженной в Северо-Восточном Приазовье, с формовочной массой продукции мастерских Юго-Восточного Крыма (которая составляет около 80% от общего количества глазурованной керамики нижнедонских османских крепостей) не исключает наличия среди них изделий крымских гончаров, имитировавших, судя по всему, итальянскую и малоазийскую посуду с модным в то время мраморовидным декором. Серия будущих петрографических, рентгеноструктурных и химических анализов внесет ясность в решение данного вопроса.

The high-sensitivity magnetometer used for the NMR detection, enables simultaneously the measurement of the static field produced in the sample proximity by ferromagnetic contaminants. The presence of the latter is studied by high resolution chemical analyses of the surface, based on X-ray fluorescence spectroscopy and secondary ions mass spectroscopy. Methodologies to reduce the contamination are explored and characterized. This study is of relevance in any ULF-NMR experiment, as in the ULF regime spurious ferromagnetism becomes easily a dominant cause of artefacts.

description: A recent study associate carbon with single photon emitters (SPEs) in hexagonal boron nitride (h-BN). This observation, together with the high mobility of carbon in h-BN suggest the existence of SPEs based on carbon clusters. Here, by means of density-functional theory calculations we studied clusters of substitutional carbon atoms up to tetramers in hexagonal boron nitride. Two different conformations of neutral carbon trimers have zero-point line energies and shifts of the phonon sideband compatible with typical photoluminescence spectra. Moreover, some conformations of two small C clusters next to each other result in photoluminescence spectra similar to those found in experiments. We also showed that vacancies are unable to reproduce the typical features of the phonon sideband observed in most measurements due to the large spectral weight of low-energy breathing modes, ubiquitous in such defects.

description: В статье публикуется шлем из коллекции «Фонда Марджани». Данный экземпляр относится к группе шлемов типа spangenhelme, которые датируются VI—VII вв. Вместе с тем, публикуемый экземпляр уникален, и имеет некоторые особенности, выделяющие его из данной группы шлемов. В нем сочетаются элементы оформления как византийской, так и сасанидской оружейной традиций. В декоре шлема присутствуют символы христианской традиции, которые выступают в качестве апотропея для владельца шлема. Хотя место и обстоятельства находки шлема неизвестны, исходя из смешения элементов византийской и сасанидской традиций украшения шлемов, можно предполагать, что шлем был изготовлен на Кавказе, на территории где одинаково сильным было влияние как со стороны Византии, так и Сасанидской Персии.

description: The idea of diffractive processes with a hard scale involved, to resolve the underlying parton dynamics, was published 1985 and experimentally verified 1988. Today hard diffraction is an active research field with high-quality data and new theoretical models. The trend from Regge-based pomeron models to QCD-based parton level models has given insights on QCD dynamics involving perturbative gluon exchange mechanisms, including the predicted BFKL-dynamics, as well as novel ideas on non-perturbative colour fields and their interactions. Extrapolations to the LHC include the interesting possibility of diffractive Higgs production.

description: This article describes and discusses a series of archaeological sites. All the sites contain an ancient enclosure built using clearly pre-medieval masonries, inside of which a number of churches have been built. The dates of these fortified structures, usually improperly defined as built using “cyclopean technique”, cannot be established without archaeological excavations. Recent attempts have been made to establish functional continuity between the ancient enclosures and the churches inside them. The goal of this text is to present and discuss these interesting sites and analyse the available data relating to the function of these structures from a diachronic perspective.
Using Ripley's K-function to Characterize Clustering In 3-Dimensional Point Patterns With a Case Study in Atom Probe Tomography

description: The size and structure of spatial molecular and atomic clustering can significantly impact material properties and is therefore important to accurately quantify. Ripley's K-function (K(r)), a measure of spatial correlation, can be used to perform such quantification when the material system of interest can be represented as a marked point pattern. This work demonstrates how machine learning models based on K(r)-derived metrics can accurately estimate cluster size and intra-cluster density in simulated three dimensional (3D) point patterns containing spherical clusters of varying size; over 90% of model estimates for cluster size and intra-cluster density fall within 11% and 18% error of the true values, respectively. These K(r)-based size and density estimates are then applied to an experimental APT reconstruction to characterize MgZn clusters in a 7000 series aluminum alloy. We find that the estimates are more accurate, consistent, and robust to user interaction than estimates from the popular maximum separation algorithm. Using K(r) and machine learning to measure clustering is an accurate and repeatable way to quantify this important material attribute.

description: We report the results of time-resolved photometric and spectroscopic near-infrared observations of the Ofpe/WN9 star and LBV candidate GCIRS34W in the Galactic Centre star cluster. Diffraction limited resolution photometric observations obtained in H and K bands show a strong, non-periodic variability on time scales from months to years in both bands accompanied by variations of the stellar colour. Three K band spectra obtained in 1996, 2003 and 2004 with integral field spectrometers are identical within their accuracies and exclude significant spectroscopic variability. The most probable explanation of the stellar photometric variability is obscuration by circumstellar material ejected by the star. The approximated position of GCIRS34W in a HR diagram is located between O supergiants and LBVs, suggesting that this star is a transitional object between these two phases of stellar evolution.

description: В статье рассматривается вопрос о том, в какой мере мероприятия понтийского царя Митридата VI Евпатора в отношении рабов могут быть свидетельством наличия у него планов социального переустройства общества. Античные авторы отмечают, что царь Понта впервые отметил роль рабов в своем указе об истреблении римлян, изданном в городе Эфес в 88 г. до н.э. В этом указе царь призывает рабов доносить на своих господ. В последующих указах царь освобождает рабов и призывает их на службу в свою армию. И призыв царя доносить на господ, и освобождение рабов для службы в армии, согласно тексту наших источников относятся только к рабам римской провинции Азия, завоеванной Митридатом. И, наконец, в сообщении Аппиана указывается, что Митридат знал о восстании рабов в Италии под руководством Спартака. Все эти сведения некоторые авторы трактуют как наличие у царя «широкомасштабного плана социальных реформ». В ряде сообщений античных авторов о Митридатовых войнах указываются и действия римлян по отношению к рабам, которые практически не отличаются от действий Митридата. Все это позволяет говорить, что у царя Понта не было плана социальных реформ и его действия по отношению к рабам диктовались исключительно планами борьбы с Римом.

Epitaxial growth of dilute nitride-arsenide compound semiconductors by molecular beam epitaxy

description: In[sub y]Ga[sub 1-y]As[sub1-x]N[sub x] containing a small amount of nitrogen (x<0.05) is a new narrow bandgap semiconductor alloy that has advantageous properties for the fabrication of optoelectronic devices. In this thesis, we seek to improve the material quality of InGaAsN and GaAsN by studying how the epitaxial growth conditions affect both the structural and electronic properties of the alloy. We describe a novel RF plasma source based on a helical resonator design that was developed for the incorporation of nitrogen into GaAsN and InGaAsN thin films grown by molecular beam epitaxy. The plasma source is equipped with a baffle apparatus that decreases the ion content of the flux. We show how the structural and electronic properties of InGaAsN epilayers depend on the growth conditions. In situ light scattering measurements and atomic force microscopy show that a faceted surface morphology occurs when growth conditions increase adatom surface diffusion: slow growth rate, high substrate temperature and high V/III ratio. Large nitrogen concentrations also favour the faceted growth mode. The residual strain in relaxed InGaAsN films is found to be higher than in InGaAs epilayers having the same lattice mismatch. In situ substrate curvature measurements were used to monitor the strain state of. the sample in real time during the growth. Ex situ transmission electron microscopy and x-ray diffraction measurements agree with the residual strain determined with the in situ monitor. These characterization results also indicate that threading dislocation glide is slower in InGaAsN than in InGaAs. Finally, we find that the electronic properties of InGaAsN are generally degraded with increasing nitrogen content. However, by choosing appropriate growth conditions, we demonstrate InGaAsN quantum wells with room temperature photoluminescence efficiencies that are comparable to InGaAs structures. These photoluminescence results may be related to the faceting transition that was observed during GaAsN growth. In contrast with the findings of other groups, rapid thermal anneals only moderately improve the photoluminescence intensity and line shape of InGaAsN single quantum wells. We observe peak intensity gains on the order of 2 after one minute anneals at 785°C. Hall measurements indicate that the electron mobility of Si-doped GaAsN is inversely proportional to the nitrogen content. We conclude that nitrogen-related neutral impurity scattering is the limiting factor in the electron mobility of GaAsN. The use of Bi as a surfactant during growth is shown to improve the surface morphology of GaAsN epilayers and the photoluminescence properties of InGaAsN single quantum wells. This work provides insight into some of the key issues that must be taken into account in the growth of dilute nitrides.

description: Recent work has observed that one can outperform exact inference in Bayesian neural networks by tuning the "temperature" of the posterior on a validation set (the "cold posterior" effect). To help interpret this phenomenon, we argue that commonly used priors in Bayesian neural networks can significantly overestimate the aleatoric uncertainty in the labels on many classification datasets. This problem is particularly pronounced in academic benchmarks like MNIST or CIFAR, for which the quality of the labels is high. For the special case of Gaussian process regression, any positive temperature corresponds to a valid posterior under a modified prior, and tuning this temperature is directly analogous to empirical Bayes. On classification tasks, there is no direct equivalence between modifying the prior and tuning the temperature, however reducing the temperature can lead to models which better reflect our belief that one gains little information by relabeling existing examples in the training set. Therefore although cold posteriors do not always correspond to an exact inference procedure, we believe they may often better reflect our true prior beliefs.
