An investigation of the Luscher colour test
Creators: name: Melhuish, Peter William
Publisher: name: University of British Columbia
Year: 2011

description: The Lüscher Colour Test was subjected to examination. A survey of psychological investigation of colour responding precedes the experimental part of the thesis. Colour, preference, the determinants of colour preference, and colour meanings are examined specifically. Part Two consists of four experimental studies. The first was an application of colour measurement techniques to the coloured stimuli on the test. Results showed important differences in the colours on three published versions of the same test, whereas in fact they are supposed to be the same. A rationale explaining Lüscher's choice of colours to comprise any one version however, was not apparent. A second study examined the applicability of the test with colour-deficient persons. Certain of the test stimuli in particular were found to be indistinguishable in hue to dichromats. No differences in Lüscher colour preferences between 18 colour-deficient subjects and a control group were found, however. Sixteen depressives, 16 nonpsychiatric hospitalized, and 16 nonpsychiatric nonhospitalized persons were administered the Lüscher Colour Test in a third study. The test was only able to differentiate between a psychiatric and a nonpsychiatric population when colour preferences were scored via the Lüscher method of interpretating preferences. Without this interpretation the test cannot make such a distinction. Finally, 15 persons were administered the test in a longitudinal study. Results showed that colour preferences changed noticeably from week to week, implying that personalities would also change accordingly. The results taken collectively suggested that the Lüscher test is not a valuable aid to personality diagnosis and research.

description: We present the experimental observation of the superlensing effect in a slab of a one-dimensional photonic crystal made of tilted dielectric elements. We show that this flat lens can achieve subwavelength resolution in different frequency bands. We also demonstrate that the introduction of a proper corrugation on the lens surface can dramatically improve both the transmission and the resolution of the imaged signal.

Public administrative building and urban revitalization
Creators: name: Shuckburgh, Brian John
Publisher: name: University of British Columbia
Year: 2011

description: In many North American Cities various levels of government are faced with pressing accomodation problems. In seeking to resolve these problems major investments in land and structures are taking place with potentially significant impacts upon the urban core. The study undertaken in this thesis examines the nature of these investments in terms of their potential contribution to the revitalization of the urban core. This goal has been frequently expressed of the location criteria formulated in conjunction with the investment. Two complementary concepts are presented which provide a theoretical basis for the utilization of the location decision as a tool for urban revitalization. The concepts take into account not only basic functional linkages between urban activities, but also values motivating individual and group behaviour. Characteristic social and economic behaviour is presented pertaining to the social and economic environment of the urban core. These behavioural characteristics provide a basis for expecting that a location decision will have a desired effect upon core revitalization. Social behaviour is discussed in terms of the individuals' personal, social, and cultural relationships to the urban environment. Economic behaviour is discussed in terms of investment motivation pertaining to the use and ownership of real property under general conditions of the real estate market and under specific market conditions created by a public investment. Empirical application of the theoretical planning concepts is examined through a study of the impacts emanating from the location for the City Hall, Victoria, B.C. The investment is examined in terms of changes in social and economic behaviour at the level of the location neighbourhood and throughout the city. Evaluation of these changes is made in the context of planning policy within the city at a time of the investment decision. Conclusions derived from the study of behavioural changes indicate that the investment fostered desired revitalization through changes in both actions and attitudes with respect to the study neighbourhood. Conclusions derived from examination of the planning context within which the decision was made indicate that certain unplanned consequences have also emerged as a result of the decision. The behavioural characteristics associated with public administrative buildings in the urban core and the successful stimulation of these characteristics in an empirical situation is submitted as evidence of the potential of a location decision to be used as a planning tool to foster core revitalization when the location decision is an integral component of a comprehensive approach to urban development.

description: We present limits on the ejection of old-population HVS from a sample of over 290,000 stars selected from the SDSS. We derive the speed at the solar circle from the measured positions and radial velocities by assuming a radial orbit and adopting a simple isothermal model of the Galactic halo, which enables us to identify candidate bound and unbound ejectees. We find 4 candidate bound F-stars from this sample, all with negative Galactocentric radial velocity (i.e., returning toward the GC). We additionally find 2 candidate unbound stars (one F and one G), however, existing proper motion measurements make these unlikely to be emerging from the GC. These data place an upper limit on the rate of ejection of old-population stars from the GC of ~45/Myr. Comparing to the rate for more massive B-star ejectees of ~0.5/Myr, our limit on the rate of ejection of old-population HVS shows that the mass function at the GC is not bottom-heavy and is consistent with being normal. Future targeted surveys of old-population HVS could determine if it is indeed top-heavy.

Interpolating optimal transport barycenters of patient manifolds
Creators: name: Tong, Alexander
name: Krishnaswamy, Smita
Publisher: name: F1000 Research Limited
Year: 2020

description: Single-cell data is now being collected across many patients in varying conditions. However, data is still relatively expensive. This opens up the opportunity for computational methods to decrease overall cost by inferring a single-cell measurement based on similarity to the meta-data of other similar samples. We examine this problem with an optimal transport perspective. This allows us to leverage a variant of the Sinkhorn algorithm for extremely computationally efficient approximations of transport along discrete manifolds. Our method first constructs the manifold between samples, then aligns this to the manifold of patients, and finally applies this to interpolate a barycenter sample along this manifold. We show first that we are able to better interpolate samples between timepoints than existing methods e.g. Waddington-OT (Schiebinger et al. 2019 Cell) by accounting for structure between multiple timepoints instead of pairs. We then show when the relationship between patients is an inferred manifold, how to impute a patient’s single-cell measurements based on other similar single-cell samples by aligning the manifold of patients with that of single-cell measurements. When the manifold of patients exhibits non-linear but intrinsically low-dimensional structure, we are able to more accurately infer a single-cell measurement.

Subjects: subject: General Topology (math.GN)

description: Let E be a topological space and F a uniform space. We introduce a new topology (in fact a uniform structure) called the V-congergence on the space of applications from E to F such that C(E,F) is closed for this topology and the restriction of this topology to C(E,F) is equivalent to pointwise convergence. In other words this topology is the coarsest preserving continuity. We give a criterion of convergence for this topology not involving the limit. Among properties preserved are mesurability and alpha-borelianity for a countable ordinal alpha.

description: We investigate the dominant physical effects of superhorizon fluctuations in a flat FLRW universe, focusing on whether the combined evolution of scalar and tensor adiabatic modes in the near-horizon regime could lead to geometries beyond those predicted by the conventional separate-universe approach. Assuming a matter-dominated universe and working to first order in perturbations but second order in a gradient expansion, we identify modes that are either pure gauge or unsourced, making them observationally irrelevant. This allows us to derive an effective metric that preserves the spatial symmetries of three well-known Bianchi cosmologies, namely, types I, V, and IX. In this framework, scalar perturbations induce spatial curvature, while the shear arises from long-wavelength tensor perturbations.

We also provide the corresponding RPAF projector augmented wave (PAW) and ultrasolf pseudopotentials for most elements. Lastly, we benchmark the performance of the RPAF by calculating the equilibrium lattice constant and bulk modulus of a set of the same 60 crystals used by other authors to benchmark other functionals for both PAW and ultrasoft pseudopotentials. We find that the RPAF performs better overall as compared to the other most popular functionals.

Time damping of non-adiabatic magnetohydrodynamic waves in a partially ionized prominence plasma: Effect of helium

description: Prominences are partially ionized, magnetized plasmas embedded in the solar corona. Damped oscillations and propagating waves are commonly observed. These oscillations have been interpreted in terms of magnetohydrodynamic (MHD) waves. Ion-neutral collisions and non-adiabatic effects (radiation losses and thermal conduction) have been proposed as damping mechanisms. We study the effect of the presence of helium on the time damping of non-adiabatic MHD waves in a plasma composed by electrons, protons, neutral hydrogen, neutral helium (He I), and singly ionized helium (He II) in the single-fluid approximation. The dispersion relation of linear non-adiabatic MHD waves in a homogeneous, unbounded, and partially ionized prominence medium is derived. The period and the damping time of Alfven, slow, fast, and thermal waves are computed. A parametric study of the ratio of the damping time to the period with respect to the helium abundance is performed. The efficiency of ion-neutral collisions as well as thermal conduction is increased by the presence of helium. However, if realistic abundances of helium in prominences (~10%) are considered, this effect has a minor influence on the wave damping. The presence of helium can be safely neglected in studies of MHD waves in partially ionized prominence plasmas.

description: We study the the high spin expansion of the anomalous dimension for long operators belonging to the $sl(2)$ sector of ${\cal N}=4$ SYM. Keeping the ratio $j$ between the twist and the logarithm of the spin fixed, the anomalous dimensions expand as $γ= f(g,j)\ln s + f^{(0)}(g,j)+O(1/\ln s)$. This particular double scaling limit is efficiently described, up to the desired accuracy $O(\ln s ^0)$, in terms of linear integral equations. By using them, we are able to evaluate both at weak and strong coupling the sub-leading scaling function $f^{(0)}(g,j)$ as series in $j$, up to the order $j^5$. Thanks to these results, the possible extension of the liaison with the O(6) non-linear sigma model may be tackled on a solid ground.

description: This paper investigates three spectroscopic techniques - Tunable Diode Laser Absorption Spectroscopy (TDLAS), Wavelength Modulation Spectroscopy (WMS), and Heterodyne Phase Sensitive Dispersion Spectroscopy (HPSDS) - to evaluate their performance in detecting carbon monoxide (CO) in nitrogen in a 31 m Herriot cell using an Interband Cascade Laser (ICL) emitting at 4559 nm. With the developed spectrometer, we can switch between the techniques with minimal hardware modifications. Calibration curves were established using simple peak-to-peak values from the recorded TDLAS, WMS, and HSPDS spectra, as well as after applying respective spectral models of the sensor responses followed by a least-squares fitting approach. We compare the results when using the different techniques with respect to obtained linearity, minimum detectable value (MDV), standard deviation of the method (sx0), coefficient of variation of the method (Vx0), limit of detection (LOD), and Allan-Werle deviation analysis. The results show significant differences in the performance of the three techniques when establishing calibration curves based on peak-to-peak evaluation of the recorded spectra. However, when establishing model-based calibration curves, a more uniform performance of the investigated techniques was found. The results demonstrate that TDLAS is a straightforward and robust technique but has a limited measurement range of up to 65 ppm. WMS offers a linear range of up to 100 ppm if an appropriate spectral model is applied and a baseline-free operation but requires careful calibration. HPSDS stands out for its wide linear range of up to 100 ppm and immunity to power fluctuations. However, its operation requires a complex mathematical model and radio frequency (RF) components.

description: RNA editing and its regulation is increasingly being recognized as an important mechanism in disease pathogenesis. With the growing availability of deep RNASeq datasets, the opportunity for global detection of RNA editing events has become achievable. However, despite advances, reliably detecting RNA editing events in the transcriptome remains difficult.
Here we introduce Balanced Output of RNA Editing (BORE), a cloud-native application that provides researchers with the ability to process their own High Throughput Sequencing data and find potential RNA editing sites. The Application is written in Python and Go, and is hosted on Amazon Web Services (AWS).
The Application uses AWS Simple Storage Service (S3) to store the raw FASTQ files. It then processes the files through the BORE Pipeline to generate candidate RNA editing sites. The results are then available to download by the researcher.
The internal workflow of BORE is: download a FASTQ file, align it to a reference genome with HiSAT2, and then preprocess into a filtered high-quality BAM File. The main processing workflow then takes over. We filter out known Single Nucleotide Variants (SNVs), generate an internal representation of the putative editing sites, and represent them as machine-readable files like VCF and as a summary report.

description: Language Identification (LID) is a crucial preliminary process in the field of Automatic Speech Recognition (ASR) that involves the identification of a spoken language from audio samples. Contemporary systems that can process speech in multiple languages require users to expressly designate one or more languages prior to utilization. The LID task assumes a significant role in scenarios where ASR systems are unable to comprehend the spoken language in multilingual settings, leading to unsuccessful speech recognition outcomes. The present study introduces convolutional recurrent neural network (CRNN) based LID, designed to operate on the Mel-frequency Cepstral Coefficient (MFCC) characteristics of audio samples. Furthermore, we replicate certain state-of-the-art methodologies, specifically the Convolutional Neural Network (CNN) and Attention-based Convolutional Recurrent Neural Network (CRNN with attention), and conduct a comparative analysis with our CRNN-based approach. We conducted comprehensive evaluations on thirteen distinct Indian languages and our model resulted in over 98\% classification accuracy. The LID model exhibits high-performance levels ranging from 97% to 100% for languages that are linguistically similar. The proposed LID model exhibits a high degree of extensibility to additional languages and demonstrates a strong resistance to noise, achieving 91.2% accuracy in a noisy setting when applied to a European Language (EU) dataset.

Effect of heat treatment on some nutrient characteristics of rapeseed meal
Creators: name: Sadiq, Mohammad
Publisher: name: University of British Columbia
Year: 2011

description: The effect of heat treatment on the protein quality and the metabolizable energy value of rapeseed meal was investigated. Different rapeseed meal samples were autoclaved at 121° c for different times. a significant reduction (p < 0.05) in the in vitro protein digestibility resulted from the autoclaving treatment. Further reduction in protein digestibility occurred when samples were autoclaved with glucose. Poor growth and feed efficiency in the chicks were observed due to feeding of autoclaved rapeseed meal ration. Lysine supplementation of autoclaved and unautoclaved rapeseed meal improved growth and feed efficiency. Maximum growth on the control ration was obtained with 0.16% lysine supplementation whereas 0.24% maximized the growth of chicks on autoclaved rapeseed meal. No significant effect was observed on liver weight expressed as percentage of body weight, however, pancreas weight was significantly greater (p < 0.05) in birds receiving autoclaved rapeseed meal than the controls. There was no significant difference in metabolizable energy value of autoclaved and unautoclaved rapeseed meals.

description: The Einstein-Rosen "bridge" wormhole solution proposed in the classic paper [1] does not satisfy the vacuum Einstein equations at the wormhole throat. We show that the fully consistent formulation of the original Einstein-Rosen "bridge" requires solving Einstein equations of bulk D=4 gravity coupled to a lightlike brane with a well-defined world-volume action. The non-vanishing contribution of Einstein-Rosen "bridge" solution to the right hand side of Einstein equations at the throat matches precisely the surface stress-energy tensor of the lightlike brane which automatically occupies the throat ("horizon straddling") - a feature triggered by the world-volume lightlike brane dynamics.

Отмечены некоторые особенности в расположении и в конструкции памятника, которые до сих пор не нашли удовлетворительного объяснения с точки зрения чистой археологии. Здесь формулирована интердисциплинарная археоастрономическая гипотеза ритуального типа о назначении этого памятника. Проведены измерения в очень трудных условиях. Предварительные результаты говорят в пользу новой гипотезы. С ее помощью впервые становится возможным дать некоторое рациональное объяснение упомянутых особенностей храма-колодца в Гырло. Объект в Гырло сравнивается с аналогическими памятниками в Сардинии и в Крыму.
description: A detailed description is presented of the ancient underground well temple of Sardinian type which was found in Bulgaria in 1971 near the village Garlo. Some interesting peculiarities in the localization and in the construction of the monument are analyzed. Up to now they do not have any satisfactory explanation in the frames of pure archaeology. A new hypothesis of archaeoastronomical and ritual character is proposed here about the function of the temple. The results from preliminary indirect measurements support this hypothesis. For the first time we are able to give a rational explanation of the peculiarities mentioned above. The Gyrlo temple is compared with similar constructions in Sardinia and Crimea.
DeepPS: a transformer model for predicting general and kinase-specific phosphorylation sites

description: Deep learning has become an innovative tool for detecting phosphorylation sites within a protein. However, the imbalance between negative and positive sites makes it challenging for a deep learning model to classify all sites accurately. Although identifying additional sites is possible, it is often costly and time-consuming with existing methods. Therefore, there is a demand for innovative modelling techniques that can overcome these limitations. To address these issues, we have designed a modelling scheme that utilises both convolutional and transformer-based neural networks. Specifically, we explore how both types of network can be combined and trained using a loss function employed in computer vision to form a robust architecture that is less likely to overfit to any one class when compared to previous baselines. We evaluate our model on a general phosphorylation site dataset, and a variety of kinase-specific datasets, including CDK, CK2, MAPK, PKA and PKC. Finally, to emphasise that this is an example of white-box deep learning, we discuss how one can visualise the model's features to gain a better understanding behind the prediction of each site.

description: Huge amount of information is present in the World Wide Web and a large amount is being added to it frequently. A query-specific summary of multiple documents is very helpful to the user in this context. Currently, few systems have been proposed for query-specific, extractive multi-document summarization. If a summary is available for a set of documents on a given query and if a new document is added to the corpus, generating an updated summary from the scratch is time consuming and many a times it is not practical/possible. In this paper we propose a solution to this problem. This is especially useful in a scenario where the source documents are not accessible. We cleverly embed the sentences of the current summary into the new document and then perform query-specific summary generation on that document. Our experimental results show that the performance of the proposed approach is good in terms of both quality and efficiency.

description: In this paper I develop a theoretical analysis of a two gear eccentric system in the Antikythera Mechanism, the oldest known analog computer. One gear carries a pin and as it rotates it transmits the motion to the other gear, which has an aperture. The angular velocity of the second gear depends from the shape of the aperture. Until now it was believed that the aperture was an orthogonal parallelogram. Prof. Xenophon Moussas expressed the idea that its shape could also be an ellipse or ellipse like. In this work the shapes Slot, Ellipse and Parabola are examined. The resulting motion of the gears is determined by a model in the framework of Lagrangian Mechanics. The theoretical results of the three shapes are compared with ephemeris data in order to specify which of them fits better with the data.

description: We investigate fermion pairing in the unitary regime for a mass ratio corresponding to a 6Li-40K mixture using Quantum Monte Carlo methods. The ground-state energy and the average light and heavy particle excitation spectrum for the unpolarized superfluid state are nearly independent of the mass ratio. In the majority light system, the polarized superfluid is close to the energy of a phase separated mixture of nearly fully polarized normal and unpolarized superfluid. For a majority of heavy particles, we find an energy minimum for a normal state with a ratio of ~ 3:1 heavy to light particles. A slight increase in attraction to kF*a ~ 2.5 yields a ground state energy of nearly zero for this ratio. A cold unpolarized system in a harmonic trap at unitarity should phase separate into three regions, with a shell of unpolarized superfluid in the middle.

MEDIEVAL ART
TOTAL SOLAR ECLIPSE OF 1239

description: Cortemilia, a town in Piedmont (Italy), is located in an area that in ancient times belonged to Ligurian tribes then conquered by the Romans. At the edge of the town is the Romanesque church of Santa Maria (Sancta Maria de Plebe) of the twelfth or thirteenth century. The magnetic and astronomical survey of church showed an orientation of its axis in the direction of the local rising of the Sun at the Equinoxes. On a wall inside the church is a beautiful sandstone bas-relief. In its center is the Virgin Mary with a crown, sitting on a throne with the baby Jesus on her lap. The measures and overall harmony of the relief reflects the medieval mystic symbolism (the divine Trinity, the Perfection of God, the Virgin and Jesus seen as intermediaries between God and men). In the frame surrounding the Virgin are symbols associated with the stars, among them a Sun that is going to be "swallowed up" by a sickle-shaped Moon. On manuscripts of the same period we saw that this symbol can be easily attributed to the representation of a total solar eclipse visible from the area of Cortemilia on June 3rd 1239, in the same period when the church was built. It took place more than five centuries after from the previous one: this surely increased the emotional impact of the event of the population, since at that time it was believed there was a close relationship between the total solar eclipses and the omens of divine doom. These feelings are evident also in the written descriptions of that eclipse that came down to us. But also the position of the stars that were visible when the sun was darkened may be the basis of the interpretation of the astral symbols and of their position on the bas-relief: perhaps the anonymous sculptor wanted to 'freeze' on the stone information related to the spectacular astronomical event that he himself had witnessed. The parish church of Santa Maria in Cortemilia and its extraordinary relief are two priceless treasures, a wonderful example of art, culture and astronomical knowledge of the Middle Ages.
Developing hospital pharmacy services based on unit dose drug distribution
Creators: name: Hill, David Stewart

description: There are many examples in the literature of conventional or traditional drug distribution systems in hospitals which possess many shortcomings with reference to medication errors, the amount of time spent by nursing personnel in medication-related duties, inventory losses, the preparation of intravenous admixtures, and the lack of adequate drug usage records. These deficiencies primarily are due to the pharmacist's minimal influence over the control of the traditional drug distribution systems. An analysis and evaluation of the present pharmacy services at St. Paul's Hospital, Vancouver, B.C., similarly identified a traditional distribution system subject to many of the aforementioned potential problems. Using information based on existing unit dose systems as reviewed in the literature and data collected from a general questionnaire, new pharmacy services based on unit dose drug distribution are projected for St. Paul's Hospital. The required facilities and personnel for a progressive unit dose drug distribution system, an intravenous (I.V.) admixture preparation service and a drug surveillance program are projected accordingly. It would appear that a "centralized" approach to implementing unit dose distribution is most appropriate for St. Paul's Hospital's present requirements. This would involve the preparation and distribution of all drugs to nursing units in single dose packages from a central pharmacy area. A similarly centralized intravenous admixture service and a decentralized drug surveillance program also are described. These services commonly feature a greater responsibility being placed with the pharmacy department for preventing therapy problems such as admixture incompatibilities, drug interactions, adverse drug reactions and inappropriate drug selection. The effect of the above services on the responsibilities and number of pharmacy and nursing personnel is estimated based on results in similar programs. These changes also reflect extended hours of coverage in each area. Finally, a potential phasing plan and time schedule for the implementation of the proposed unit dose drug distribution system, I.V. admixture preparation service and drug surveillance program at St. Paul's Hospital is suggested.

description: Studies combining PCR techniques and next-generation DNA sequencing (NGS) to characterize the HIV genetic diversity and understand the reservoir dynamics have been extensively reported. In such investigation thousands of sequences are generated, requiring automation in the characterization process. Here we present the Defective and Intact HIV genome Assembler (DIHIVA), a pipeline to annotate and classify HIV genomes based on NGS data. First, we remove PCR amplification and perform error correction using BBtools. After, a quality-control check is carried out by Trim Galore package to trim Illumina adapters and low-quality bases. BBtools is also used to remove possible contaminant reads using HIV genome sequences obtained from Los Alamos HIV database. We then use SPAdes, a k-mer based assembler, to reconstruct the HIV-1 sequences. The longest assembled contig is aligned via BLAST to the Los Alamos HIV genome database, in order to set it in the forward orientation. Finally, the HIV genome is annotated against Hxb2 using BLAST. In the end, sequences are classified as intact or defective, which could be Major Splicing Donor (MSD) Mutation, Non-functional, Missing Internal Genes or Weird. In order to provide access to non-computer specialists we developed a user-friendly interface for the pipeline using R/Shiny.

A determination of dark matter bispectrum with a large set of N-body simulations

description: We use a set of numerical N-body simulations to study the large-scale behavior of the reduced bispectrum of dark matter and compare the results with the second-order perturbation theory and the halo models for different halo mass functions. We find that the second-order perturbation theory (PT2) agrees with the simulations fairly well on large scales of k<0.05 h/Mpc, but it shows a signature of deviation as the scale goes down. Even on the largest scale where the bispectrum can be measured reasonably well in our simulations, the inconsistency between PT2 and the simulations appears for the colinear triangle shapes. For the halo model, we find that it can only serve as a qualitative method to help study the behavior of Q on large scales and also on relatively small scales. The failure of second-order perturbation theory will also affect the precise determination of the halo models, since they are connected through the 3-halo term in the halo model. The 2-halo term has too much contribution on the large scales, which is the main reason for the halo model to overpredict the bispectrum on the large scales. Since neither of the models can provide a satisfying description for the bispectrum on scales of about 0.1h/Mpc for the requirement of precision cosmology, we release the reduced bispectrum of dark matter on a large range of scales for future analytical modeling of the bispectrum.

description: In the present work, we investigate the formation of Stokes profiles and spectro-polarimetric diagnostics in an active region plage near the limb. We use 3-D radiation-MHD simulations with unipolar fields of an average strength of 400 G, which is largely concentrated in flux tubes in which the field reaches typical kilo-Gauss values. We generate synthetic Stokes spectra by radiative transfer calculations, then we degrade the simulated Stokes signal to account for observational conditions. The synthetic data treated in this manner are compared with and found to roughly reproduce spectro-polarimetric high-resolution observations at Mu=0.39 obtained by the SOUP instrument with the Swedish 1-m Solar Telescope at the beginning of 2006.

description: I present an argument, based on the topology of the universe, why there are three generations of fermions. The argument implies a preferred gauge group of SU(5), but with SO(10) representations of the fermions. The breaking pattern SU(5) to SU(3)xSU(2)xU(1) is preferred over the pattern SU(5) to SU(4)xU(1). On the basis of the argument one expects an asymmetry in the early universe microwave data, which might have been detected already.
