description: We use cosmological hydrodynamical simulations to investigate how the inclusion of physical processes relevant to galaxy formation (star formation, metal-line cooling, stellar winds, supernovae and feedback from Active Galactic Nuclei, AGN) change the properties of haloes, over four orders of magnitude in mass. We find that gas expulsion and the associated dark matter (DM) expansion induced by supernova-driven winds are important for haloes with masses M200 < 10^13 Msun, lowering their masses by up to 20% relative to a DM-only model. AGN feedback, which is required to prevent overcooling, has a significant impact on halo masses all the way up to cluster scales (M200 ~ 10^15 Msun). Baryonic physics changes the total mass profiles of haloes out to several times the virial radius, a modification that cannot be captured by a change in the halo concentration. The decrease in the total halo mass causes a decrease in the halo mass function of about 20%. This effect can have important consequences for abundance matching technique as well as for most semi-analytic models of galaxy formation. We provide analytic fitting formulae, derived from simulations that reproduce the observed baryon fractions, to correct halo masses and mass functions from DM-only simulations. The effect of baryonic physics (AGN feedback in particular) on cluster number counts is about as large as changing the cosmology from WMAP7 to Planck, even when a moderately high mass limit of M500 ~ 10^14 Msun is adopted. Thus, for precision cosmology the effects of baryons must be accounted for.

description: We experimentally study the radii of excitons in hBN-encapsulated WS2 monolayers by means of magneto-optical reflectance spectroscopy at cryogenic temperatures in magnetic fields up to 29 T. We observe field-induced energy shifts of the exciton ground and excited states due to valley Zeeman and diamagnetic effects. We find the g factor of the first excited state of −4.2±0.1 to be essentially equal to that of the ground state of −4.35±0.1. From diamagnetic shifts, we determine the root mean square radii of the excitons. The radius of the first excited state is found to be 5–8 nm and that of the ground state around 2 nm. Our results further confirm the Wannier-Mott nature of the exciton quasiparticles in monolayer semiconductors and the assignment of the optical resonances in absorption-type measurements. They also provide additional support for the applicability of the effective mass hydrogenlike models in these systems.

description: Filter cake and Triplex are powdered by-products of aluminum sulfate and soap factories, respectively. There is limited data about the use of these powders as grain protectants. This study was aimed at determining contact toxicity of both powders against Sitophilus zeamais, a common pest of stored grains. Lethal concentration of both powders to S. zeamais was determined by exposing 10 adults for 12 h in 9 cm diameter concrete arenas inside Petri dishes dusted with filter cake (0 - 8 g/m2) or Triplex (0 - 9 g/m2). Lethal time was determined by exposing adults to 3 g/m2 filter cake and 9 g/m2 Triplex for 1 to 24 h. Each treatment was replicated 3 times. At the intended exposure time, adults were transferred to 150-ml round plastic containers with 30 g of wheat and held at 28 degree Celsius and 65% r.h. for 14 d to determine mortality. Adult progeny production was determined after 42 d. A 50% mortality of adults was obtained at 0.61 g/m2 of filter cake and 1.61 g/m2 of Triplex concentrations with a 12 h exposure. The corresponding effective concentrations for 50% reduction of progeny production were 0.18 g/m2 of filter cake and 2.66 g/m2 of Triplex. Lethal times for 50% mortality of adults after exposure to 3 g/m2 of filter cake and 9 g/m2 of Triplex were 4.42 and 4.29 h, respectively. The corresponding effective times for 50% reduction of progeny production after exposure to 3 g/m2 of filter cake and 9 g/m2 of Triplex were 1.74 and 2.34 h respectively. The overall result indicated that filter cake was highly toxic to S. zeamais than Triplex. Therefore, filter cake is a potential powder to be included in the integrated pest management practice in small holder farmers’ storage structures after tested under real field conditions.

description: We directly monitor exciton propagation in freestanding and SiO2-supported WS2 monolayers through spatially and time-resolved microphotoluminescence under ambient conditions. We find a highly nonlinear behavior with characteristic, qualitative changes in the spatial profiles of the exciton emission and an effective diffusion coefficient increasing from 0.3 to more than 30 cm2/s, depending on the injected exciton density. Solving the diffusion equation while accounting for Auger recombination allows us to identify and quantitatively understand the main origin of the increase in the observed diffusion coefficient. At elevated excitation densities, the initial Gaussian distribution of the excitons evolves into long-lived halo shapes with μm-scale diameter, indicating additional memory effects in the exciton dynamics.

description: Our own unique character traits make our behavior consistent and define our individuality. Yet, this consistency does not entail that we behave repetitively like machines. Like humans, animals also combine personality traits with spontaneity to produce adaptive behavior: consistent, but not fully predictable. Here, we study an iconically rigid behavioral trait, insect phototaxis, that nevertheless also contains both components of individuality and spontaneity. In a light/dark T-maze, approximately 70% of a group of Drosophila fruit flies choose the bright arm of the T-Maze, while the remaining 30% walk into the dark. Taking the photopositive and the photonegative subgroups and re-testing them reveals the spontaneous component: a similar 70–30 distribution emerges in each of the two subgroups. Increasing the number of choices to ten choices, reveals the individuality component: flies with an extremely negative series of first choices were more likely to show photonegative behavior in subsequent choices and vice versa. General behavioral traits, independent of light/dark preference, contributed to the development of this individuality. The interaction of individuality and spontaneity together explains why group averages, even for such seemingly stereotypical behaviors, are poor predictors of individual choices.

description: A new family of inflation models is introduced and studied. The models are characterised by a scalar potential which, far from the origin, approximates an inflationary plateau, while near the origin becomes monomial, as in chaotic inflation. The models are obtained in the context of global supersymmetry starting with a superpotential, which interpolates from a generalised monomial to an O'Raifearteagh form for small to large values of the inflaton field respectively. It is demonstrated that the observables obtained, such as the scalar spectral index and the tensor to scalar ratio, are in excellent agreement with the latest observations. Some discussion of initial conditions and eternal inflation is included.

Do The Inward And Outward Foreign Direct Investments Spur Domestic Investment In Bangladesh? A Counterfactual Analysis

description: The net contribution of the decomposed measures of foreign direct investment (FDIs), e.g., the inward and outward flows of FDIs, to domestic investment is still inconclusive in the case of underdeveloped and developing countries. The current literature bears testimony to this fact. Hence, this research examines the impact of inward and outward foreign direct investments (FDIs) on the domestic investment in Bangladesh. This study considers annual time series data from 1976 to 2019 and estimates this data property under the augmented ARDL approach to cointegration. In addition, this research employs the dynamic ARDL simulation technique in order to forecast the counterfactual shock of the regressors and their effects on the dependent variable. The results from the augmented ARDL method suggest that the inward FDI has a positive impact on domestic investment, while the outward FDI is inconsequential in both the long run and the short run. Besides, our estimated findings also show the economic growth’s long-run and short-run favorable effects on domestic investment. At the same time, there is no significant impact of real interest rates and institutional quality on domestic investment in the long run or the short run in Bangladesh. In addition, the counterfactual shocks (10% positive and negative) to inward FDI positively impact domestic investment, indicating the crowding-in effect of the inward FDI on the domestic investment in Bangladesh. As the inward FDI flow is a significant determinant for sustained domestic investment in Bangladesh, the policy strategy must fuel the local firms by utilizing cross-border investment.
title: Isomorphism, cold-adaptation, and phosphorylation of sarcomeric tropomyosin

description: Tropomyosin is a dimeric protein containing 284 amino acids per chain that is found, in association with F-actin and troponin, within the thin filament, a complex that regulates muscle contraction. The thesis is composed of three results chapters: i) The existence of beta tropomyosin (Tpm2) is demonstrated for the first time in fish (Salmo salar). Compared to the mammalian homologue, salmon Tpm2 has fewer cysteine (one per chain) and tyrosine (five per chain) residues. Tpm2 contributes half of the total tropomyosin in the jaw, tongue, and fin muscles. A Tpm1 isoform, either alpha-1 chain-like isoform X1 (cheek dark, jaw and tongue) or alpha (fin), accounts for the remainder. Salmon tropomyosins are distinguishable based on electrophoretic mobility, affinity for troponin-Sepharose, tryptic peptide mapping, and variable carboxyl-terminal regions (residues 276 - 284): beta (Tpm2), Leu-Ala-Leu-Asn-Asp-Met-Thr-Thr-Leu; alpha-1 chain-like isoform X1, His-Ala-Leu-Asn-Asp-Met-Thr-Ala-Ile, and alpha (Tpm1), Asn-Ala-Leu-Asn-Asp-Met-Thr-Ser-Ile. ii) The relative instability of the most abundant isoform of Atlantic salmon, Tpm1, (20 substitutions vs. mammal) is due to a neutral 77th amino acid (Thr in salmon; Lys in rabbit), and glycines at 24 and 27 (Ala and Gln in rabbit). Incorporation of the respective mesophilic amino acid increases resistance to thermal unfolding as determined by calorimetry and chymotrypsin digestion at Leu-169, a site ⁓100 amino acids far away from residue-77. PyMOL indicates ion pairing between Lys-77 and Glu-82 in the opposite chain. Binding of Tpm1 to troponin-Sepharose is influenced by N-terminal acetylation and the mutation of residues 24, 27, and 77. Furthermore, wild type Tmp1 displays a higher affinity for F-actin at 4 ℃ (KD, ̴ 0.1 μM) than 30 ℃ (KD, ̴ 1.6 μM). In contrast, the mesophilic homologue binds less tightly to actin at lower temperatures. iii) Phosphorylation of serine 283 increases the susceptibility of mammalian Tpm1.1(α) to chymotrypsin (at Leu-169) and trypsin (at Arg-133), suggesting an induced opening of the center of the molecule >150 amino acids upstream, and shifts the corresponding portion of the circular dichroism unfolding profile. These results infer a change in exposure of actin-binding periods 4 (residues 124 - 147) and 5 (residues 166 - 189). The proposal is consistent with a two-fold increase in affinity for F-actin in co-sedimentation experiments.

description: Spin pumping and spin-transfer torques are two reciprocal phenomena widely studied in ferromagnetic materials. However, pumping from antiferromagnets and its relation to current-induced torques have not been explored. By calculating how electrons scatter off a normal metal-antiferromagnetic interface, we derive pumped spin and staggered spin currents in terms of the staggered field, the magnetization, and their rates of change. For both compensated and uncompensated interfaces, spin pumping is of a similar magnitude as in ferromagnets with a direction controlled by the polarization of the driving microwave. The pumped currents are connected to current-induced torques via Onsager reciprocity relations.

description: Synthesized by the wet chemical precipitation technique hydroxyapatite powders (HAp) with the sizes of the crystallites of (20-50) nm and 1000 nm were analyzed by different analytical methods. By means of electron paramagnetic resonance (EPR) it is shown that during the synthesis process nitrate anions from the reagents (by-products) could incorporate into the HAp structure. The concentration of the stable NO32- radicals detected after X-ray irradiation of the product at room temperature does not decrease even after annealing up to 400 oC. The relaxation times and EPR parameters of the axially symmetric NO32- paramagnetic centers are measured with high accuracy. Increased sensitivity and resolution of high-frequency EPR (95 GHz) allows to reveal additional paramagnetic centre(s) which origin is discussed. Analyses of electron-nuclear double resonance (ENDOR) spectra from 1H and 31P nuclei and ab-initio density functional theory (DFT) calculations allow suggesting that the paramagnetic centers and nitrate anions as the precursors of NO32- radicals preferably occupy PO43- site in the HAp structure.

description: Stimulated by the recent discovery of the 1 yr recurrence period nova M31N 2008-12a, we examined the shortest recurrence periods of hydrogen shell flashes on mass-accreting white dwarfs (WDs). We discuss the mechanism that yields a finite minimum recurrence period for a given WD mass. Calculating the unstable flashes for various WD masses and mass accretion rates, we identified a shortest recurrence period of about two months for a non-rotating 1.38 M_sun WD with a mass accretion rate of 3.6 x 10^{-7} M_sun yr^{-1}. A 1 yr recurrence period is realized for very massive (> 1.3 M_sun) WDs with very high accretion rates (> 1.5 x 10^{-7} M_sun yr^{-1}). We revised our stability limit of hydrogen shell burning, which will be useful for binary evolution calculations toward Type Ia supernovae.

description: One of the Sakharov's condition for baryogenesis is the violation of both C and CP. In the Standard Model, gauge interactions break maximally C, but CP is only broken through the Yukawa couplings in the poorly understood scalar sector. In extra-dimensional models, extra components of gauge fields behave as scalars in 4D and can acquire effective vev's through (finite) quantum effects (Hosotani mechanism). This mechanism is used to build a toy model with 2 extra-dimensions compactified on a flat torus $T^2$, where a SU(2) gauge symmetry is broken to U(1) and CP violation (in 4D) is expected. This is verified by computing a non-vanishing electric dipole moment.

description: Passive states of quantum systems are states from which no system energy can be extracted by any cyclic (unitary) process. Gibbs states of all temperatures are passive. Strong local (SL) passive states are defined to allow any general quantum operation, but the operation is required to be local, being applied only to a specific subsystem. Any mixture of eigenstates in a system-dependent neighborhood of a nondegenerate, entangled ground state is found to be SL passive. In particular, Gibbs states are SL passive with respect to a subsystem only at or below a critical, system-dependent temperature. SL passivity is associated in many-body systems with the presence of ground state entanglement in a way suggestive of collective quantum phenomena such as quantum phase transitions, superconductivity, and the quantum Hall effect. The presence of SL passivity is detailed for some simple spin systems where it is found that SL passivity is neither confined to systems of just a few particles nor limited to the near vicinity of the ground state.

The DGS-Korpus approach to including frequent sign combinations in a corpus-based electronic sign language dictionary

Publisher: name: Universität Hamburg

description: With the availability of corpus data new kinds of information on sign use can be found and made available in sign language dictionary entries, such as different types of typical sign combinations (in the following called patterns) including phrasal units, loan compounds, collocational patterns and even patterns of semantic preference. As entries of SL dictionaries become more and more complex and include a wider variety of information types such as SL examples, the issue of sign representation becomes more pressing.
 For the compilation of the corpus-based DGS-German dictionary frequent sign combinations are extracted from the DGS-Korpus in order to include information on typical patterns into the entries. The dictionary displays properties of a genuine monolingual dictionary with entries including information on senses, usage, grammar, form variants, regional and age variation, synonyms and antonyms, relevant collocations and other patterns. Entries are compiled in a preliminary format and are published as work in progress step by step.
 In this paper we focus on patterns of sign combinations and how to integrate them into a complex entry structure. Information types that are genuine elements or stretches of the object language have to be represented in the entry in a directly accessible way. The issue of sign representation touches the core of SL lexicography: Object language elements that fulfil the function of being relevant information in themselves (i.e. that function as examples in the broader sense) need to be present first hand in the entry and cannot be substituted.
 Instead of using glosses, writing, notation or film clips, we experiment with moving icons (called micons) combined with unique entry numbers within the microstructural text of the entry. A micon is an animated image indicating the form by a still and an animation on mouse-over activation, backed up by a full-size video clip only one click away. Obviously, this is a solution solely working within the electronic medium and difficult to represent in print.
 The patterns listed in the entries are of different levels of complexity:
 1. Simple collocations of two signs, the lemma sign and a frequent neighbour, represented by two micons side by side.
 2. Complex patterns where the place of the neighbour is shared by a cluster of a limited number of lexical variants, represented by a dendrogram with the micons as nodes.
 3. Complex patterns where the neighbour can be any member of a grammatical class or a semantic group (colligation and semantic preference). Here the class or group can be large or even open e.g. number signs. The members of the neighbouring group are not lexical variants but differ in meaning. In our pattern representation, we include prominent members as examples as well as some categorical information on the group or class.
On Effects of Imperfect Channel State Information on Null Space Based Cognitive MIMO Communication

Year: 2014

description: In cognitive radio networks, when secondary users transmit in the null space of their interference channel with primary user, they can avoid interference. However, performance of this scheme depends on knowledge of channel state information for secondary user to perform inverse waterfilling. We evaluate the effects of imperfect channel estimation on error rates and performance degradation of primary user and elucidate the tradeoffs, such as amount of interference and guard distance. Results show that, based on the amount of perturbation in channel matrices, performance of null space based technique can degrade to that of open loop MIMO. Outcomes presented in this paper also apply to null space based MIMO radar waveform design to avoid interference with commercial communication systems, operating in same or adjacent bands.

Statistics of initial density perturbations in heavy ion collisions and their fluid dynamic response

Year: 2014
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: An interesting opportunity to determine thermodynamic and transport properties in more detail is to identify generic statistical properties of initial density perturbations. Here we study event-by-event fluctuations in terms of correlation functions for two models that can be solved analytically. The first assumes Gaussian fluctuations around a distribution that is fixed by the collision geometry but leads to non-Gaussian features after averaging over the reaction plane orientation at non-zero impact parameter. In this context, we derive a three-parameter extension of the commonly used Bessel-Gaussian event-by-event distribution of harmonic flow coefficients. Secondly, we study a model of N independent point sources for which connected n-point correlation functions of initial perturbations scale like 1/N^(n-1). This scaling is violated for non-central collisions in a way that can be characterized by its impact parameter dependence. We discuss to what extent these are generic properties that can be expected to hold for any model of initial conditions, and how this can improve the fluid dynamical analysis of heavy ion collisions.

description: In the presence of CP violation, the Higgs-top coupling may have both scalar and pseudoscalar components, $κ_t$ and ${\tilde κ_t}$, which are bounded indirectly but only weakly by the present experimental constraints on the Higgs-gluon-gluon and Higgs-$γ$-$γ$ couplings, whereas upper limits on electric dipole moments provide strong additional indirect constraints on ${\tilde κ_t}$, if the Higgs-electron coupling is similar to that in the Standard Model and there are no cancellations with other contributions. We discuss methods to measure directly the scalar and pseudoscalar Higgs-top couplings by measurements of Higgs production in association with ${\bar t} t$, single $t$ and single ${\bar t}$ at the LHC. Measurements of the total cross sections are very sensitive to variations in the Higgs-top couplings that are consistent with the present indirect constraints, as are invariant mass distributions in ${\bar t} t H$, $tH$ and ${\bar t} H$ final states. We also investigate the additional information on $κ_t$ and ${\tilde κ_t}$ that could be obtained from measurements of the longitudinal and transverse $t$ polarization in the different associated production channels, and the ${\bar t} t$ spin correlation in ${\bar t} t H$ events.

description: Leukopenia is one of the most harmful side effects during chemotherapy treatment, since leukocytes (L) are crucial in protecting patients against bacteria and fungi. A personalized mathematical model of dynamics of L would allow a glimpse into the future and the initiation of tailored countermeasures. We propose such a mathematical model and calibrate it based on a parameter estimation with real world data. For our study we used data of L during and after consolidation chemotherapy treatment (cytarabine) of six patients contracting acute myeloid leukemia. We compare two different ways to treat the unknown initial values of the system of ordinary differential equations, discuss patient-specificity of parameter values, and different scalings of the least squares formulation. These three comparisons are necessary considerations for all modeling approaches to biomedicine, and have thus a methodological scope beyond the specific case of leukopenia. In summary, we show that our approach is able to simulate L dynamics in response to chemotherapy treatment and allows to take patient-specific characteristics into account.

description: The majority of massive stars are formed in binary systems. It is hence reasonable to expect that most core-collapse supernovae (CCSNe) take place in binaries and the existence of a companion star may leave some imprints in observed features. Having this in mind, we have conducted two-dimensional hydrodynamical simulations of the collisions of CCSNe ejecta with the companion star in an almost-equal-mass ($\sim 10M_\odot$) binary to find out possible consequences of such events. In particular we pay attention to the amount of mass removed and its dependence on the binary separation. In contrast to the previous surmise, we find that the companion mass is stripped not by momentum transfer but by shock heating. Up to $25\%$ of the original mass can be removed for the closest separations and the removed mass decreases as $M_{ub} \propto a^{-4.3}$ with the binary separation $a$. By performing some experimental computations with artificially-modified densities of incident ejecta, we show that if the velocity of ejecta is fixed, the density of incident ejecta is the single important parameter that actually determines the removed mass as $M_{ub} \propto ρ_{ej} ^{1.4} $. On the other hand, another set of simulations with modified velocities of incident ejecta demonstrate that the strength of the forward shock, which heats up the stellar material and causes the mass loss of the companion star, is actually the key parameter for the removed mass.

description: We extend here the result of Bekenstein [1,2] proving the non-existence of minimally coupled scalar black hole hair in general relativity to the Lanczos-Lovelock gravity in arbitrary dimension with non-negative coupling constants. The only physical requirement on the multiplet of minimally coupled scalar fields is that it fulfills the weak energy condition. We also assume, similarly to Bekenstein, spherical symmetry and asymptotic flatness.

description: Catheter ablation of right ventricular outflow tract ventricular arrhythmias from above the pulmonary valve is being increasingly reported. Objective The purpose of this study was to systematically analyze the spatial relationship between the pulmonary trunk and the left coronaries. Methods Contrast-enhanced computed tomographic scans from 58 patients were analyzed. After segmentation of the pulmonary trunk and the proximal left coronaries, 3-dimensional geometries were generated. Minimal distance between the pulmonary trunk and the coronaries was automatically determined using a newly developed mathematical algorithm. Results The minimal distance between the pulmonary trunk and the coronaries was 1.4 ± 0.11 mm. Closest relationship was detected 13.8 ± 0.87 mm above the pulmonary valve annulus. Considering a safety margin of 5 mm to render coronary damage unlikely, 84% of patients were found to be at potential risk within the bottom 10 mm of the left sinus cusp. In contrast, positions within or above the right and anterior cusps were less likely to exhibit a close relationship. We identified the anterior aspect of the left cusp as the most critical region. Positions 10–20 mm above the left cusp were found to be critical in 97% of patients. Clinical parameters such as gender, age, height, weight, and body mass index were not predictive of a close spatial relationship. Conclusion Our data provide evidence for a close spatial relationship between the pulmonary trunk and coronary arteries. These results should be considered when performing catheter ablation from above the pulmonary valve.
Uncertainty in the context of multislit interferometry

description: A pair of uncertainty relations relevant for quantum states of multislit interferometry is derived, based on the mutually commuting "modular" position and momentum operators and their complementary counterparts, originally introduced by Aharonov and co-workers. We provide a precise argument as to why these relations are superior to the standard Heisenberg uncertainty relation at expressing the complementarity between spatial localisation and the appearance of fringes. We further support the argument with explicit computations involving wavefunctions specifically tailored to the interference setup. Conceptually developing the idea of Aharonov and co-workers, we show how the modular momentum should reflect the given experimental setup, yielding a refined observable that accurately captures the fine structure of the interference pattern.

description: Review papers provide a foundation for knowledge development in information systems (IS) as well as in any other scientific discipline. While some of the prominent reviews in information systems are cited more than twice a day on average, others take years to accumulate single digit citations. The magnitude of these differences and the proliferation of review papers in recent years prompt us to empirically analyze what distinguishes those reviews that have proven to be integral to scientific progress from those that might not be considered impactful. Our results demonstrate that the attributes explaining scientific impact are unique for the different types of reviews: reviews for describing, understanding, explaining, and theory testing. Transparency of the applied methodology is important for reviews that target theory testing, understanding, or explaining; similarly, reviews for describing, understanding or explaining achieve a higher impact when they develop a research agenda. By providing nuanced insights into the attributes of review papers that are valued by subsequent research, our study contributes to the vibrant discourse on literature reviews in IS. We thereby inform the different stakeholders involved in the development and publication of review papers in the IS field.

description: There are various quantum chemical approaches for an ab initio description of transfer integrals within the framework of Marcus theory in the context of electron transfer reactions. In our article we aim to calculate transfer integrals in redox-active single molecule junctions, where we focus on the coherent tunneling limit with the metal leads taking the position of donor and acceptor and the molecule acting as a transport mediating bridge. This setup allows us to derive a conductance, which can be directly compared with recent results from a non-equilibrium Green's function approach. Compared with purely molecular systems we face additional challenges due to the metallic nature of the leads, which rules out some of the common techniques, and due to their periodicity, which requires {\bf k} space integration. We present three different methods, all based on density functional theory, for calculating the transfer integral under these constraints, which we benchmark on molecular test systems from the relevant literature. We also discuss manybody effects and apply all three techniques to a junction with a Ruthenium complex in different oxidation states.
Big Bang, Blowup, and Modular Curves: Algebraic Geometry in Cosmology

description: We introduce some algebraic geometric models in cosmology related to the "boundaries" of space-time: Big Bang, Mixmaster Universe, Penrose's crossovers between aeons. We suggest to model the kinematics of Big Bang using the algebraic geometric (or analytic) blow up of a point $x$. This creates a boundary which consists of the projective space of tangent directions to $x$ and possibly of the light cone of $x$. We argue that time on the boundary undergoes the Wick rotation and becomes purely imaginary. The Mixmaster (Bianchi IX) model of the early history of the universe is neatly explained in this picture by postulating that the reverse Wick rotation follows a hyperbolic geodesic connecting imaginary time axis to the real one. Penrose's idea to see the Big Bang as a sign of crossover from "the end of previous aeon" of the expanding and cooling Universe to the "beginning of the next aeon" is interpreted as an identification of a natural boundary of Minkowski space at infinity with the Big Bang boundary.
