description: Gyrochronology is one of the methods currently used to estimate the age of stellar open clusters. Hundreds of new clusters, associations, and moving groups unveiled by Gaia and complemented by accurate rotation period measurements provided by recent space missions such as Kepler and TESS are allowing us to significantly improve the reliability of this method. We use gyrochronology, that is, the calibrated age-mass-rotation relation valid for low-mass stars, to measure the age of the recently discovered moving group Group X. We extracted the light curves of all candidate members from the TESS full frame images and measured their rotation periods using different period search methods. We measured the rotation period of 168 of a total of 218 stars and compared their period-colour distribution with those of two age-benchmark clusters, the Pleiades (125 Myr) and Praesepe (625 Myr), as well as with the recently characterised open cluster NGC3532 (300 Myr). As result of our analysis, we derived a gyro age of 300$\pm$60 Myr. We also applied as independent methods the fitting of the entire isochrone and of the three brightest candidate members individually with the most precise stellar parameters, deriving comparable values of 250 Myr and 290 Myr, respectively. Our dating of Group X allows us to definitively rule out the previously proposed connection with the nearby but much older Coma Berenices cluster.

description: Nonthermal X-rays and very high-energy (VHE) $γ$-rays have been detected from the supernova remnant (SNR) RX J1713.7-3946, and especially the recent observations with the \textit{Suzaku} satellite clearly reveal a spectral cutoff in the X-ray spectrum, which directly relates to the cutoff of the energy spectrum of the parent electrons. However, whether the origin of the VHE $γ$-rays from the SNR is hadronic or leptonic is still in debate. We studied the multi-band nonthermal emission from RX J1713.7-3946 based on a semi-analytical approach to the nonlinear shock acceleration process by including the contribution of the accelerated electrons to the nonthermal radiation. The results show that the multi-band observations on RX J1713.7-3946 can be well explained in the model with appropriate parameters and the TeV $γ$-rays have hadronic origin, i.e., they are produced via proton-proton (p-p) interactions as the relativistic protons accelerated at the shock collide with the ambient matter.

description: Pulsar timing uses the highly stable pulsar spin period to investigate many astrophysical topics. In particular, pulsar timing arrays make use of a set of extremely well-timed pulsars and their time correlations as a challenging detector of gravitational waves. It turns out that pulsar timing arrays are particularly sensitive to ultra-low-frequency gravitational waves, which makes them complementary to other gravitational-wave detectors. Here, we summarize the basics, focusing especially on supermassive black-hole binaries and cosmic strings, which have the potential to form a stochastic gravitational-wave background in the pulsar timing array detection band, and the scientific goals on this challenging topic. We also briefly outline the recent interesting results of the main pulsar timing array collaborations, which have found strong evidence of a common-spectrum process compatible with a stochastic gravitational-wave background and mention some new perspectives that are particularly interesting in view of the forthcoming radio observatories such as the Five hundred-meter Aperture Spherical Telescope, the MeerKAT telescope, and the Square Kilometer Array.

Yeast cultivation on natural starches

Publisher: name: University of British Columbia
Year: 2010

description: This research project is concerned with the use of an amylolytic yeast, Endomycopsis sp., for simultaneous production of yeast protein and crude amylase preparations from natural starch materials. The Endomycopsis yeasts were cultivated alone and in combination with other yeasts which are unable to attack starch directly. The propagations were carried out in the presence of urea and phosphate, under aerobic conditions, with vigorous agitation, at pH 5.0 and 28°C. At daily intervals, the cultures were analyzed for protein yield, cell density, and amylase activity. The cell crop harvested after propagation of Endomycops is yeasts on 6.0% potato media contained 19% protein and the culture filtrate obtained after biomass separation had an activity of 1.5 units. Variations in activity and protein content were observed, depending on the starch substrate used, the concentration of urea added, and apparently, the amount of oxygen supplied. Mixed preparations using Candida utilis as ancillary yeast, gave higher protein yields and amylase activities compared to single propagations of Endomycopsis sp. and mixed propagations with Saccharomyces cerevisiae. Purple yam and cassava tubers were examined for protein enrichment and amylase production. It was observed that the protein content of the cell crops obtained from these substrates could be increased about ten-fold but that the amylase activities of the culture filtrates were very low .

description: Low temperature solution combustion synthesis emerges as a facile method for synthesis of functional metal oxides thin films for electronic applications. We study the solution combustion synthesis process of Cu:NiOx using different molar ratios (w/o, 0.1 and 1.5) of fuel acetylacetone (Acac) to oxidizer (Cu, Ni Nitrates) as a function of thermal annealing tempera-tures 150, 200 and 300 oC. The solution combustion synthesis process, in both thin films and bulk Cu:NiOx, is investigated. Thermal analysis studies using TGA and DTA reveal that the Cu:NiOx thin films show a more gradual mass loss while the bulk Cu:NiOx exhibits a distinct combustion process. The thin films can crystallize to Cu:NiOx at annealing temperature of 300 oC irrespective to the Acac/Oxidizer ratio whereas lower annealing temperatures (150 and 200 oC) produce amorphous materials. A detail characterization study of solution combustion synthesized Cu:NiOx including XPS, UV-Vis, AFM and Contact angle measurements is presented. Finally, 50 nm Cu:NiOx thin films are introduced as HTLs within the inverted perovskite solar cell device architecture. The Cu:NiOx HTL annealed at 150 and 200 oC provided PVSCs with limited functionality whereas efficient triple-cation Cs0.04(MA0.17FA0.83)0.96 Pb(I0.83Br0.17)3 based PVSCs achieved for Cu:NiOx HTLs annealed at temperature 300 oC.

description: We demonstrate the utility of elementary head-motion units termed kinemes for behavioral analytics to predict personality and interview traits. Transforming head-motion patterns into a sequence of kinemes facilitates discovery of latent temporal signatures characterizing the targeted traits, thereby enabling both efficient and explainable trait prediction. Utilizing Kinemes and Facial Action Coding System (FACS) features to predict (a) OCEAN personality traits on the First Impressions Candidate Screening videos, and (b) Interview traits on the MIT dataset, we note that: (1) A Long-Short Term Memory (LSTM) network trained with kineme sequences performs better than or similar to a Convolutional Neural Network (CNN) trained with facial images; (2) Accurate predictions and explanations are achieved on combining FACS action units (AUs) with kinemes, and (3) Prediction performance is affected by the time-length over which head and facial movements are observed.

description: Within the Critique of practical reason, Epicurus plays an important, even if very often neglected, role. First at all in the Analytic, where the Epicurean ethics appears as the more serious opponent to the Kantian foundation of the morality.

description: Using first-principles plane wave calculations, we investigate two dimensional honeycomb structure of Group IV elements and their binary compounds, as well as the compounds of Group III-V elements. Based on structure optimization and phonon mode calculations, we determine that 22 different honeycomb materials are stable and correspond to local minima on the Born-Oppenheimer surface. We also find that all the binary compounds containing one of the first row elements, B, C or N have planar stable structures. On the other hand, in the honeycomb structures of Si, Ge and other binary compounds the alternating atoms of hexagons are buckled, since the stability is maintained by puckering. For those honeycomb materials which were found stable, we calculated optimized structures, cohesive energies, phonon modes, electronic band structures, effective cation and anion charges, and some elastic constants. The band gaps calculated within Density Functional Theory using Local Density Approximation are corrected by GW0 method. Si and Ge in honeycomb structure are semimetal and have linear band crossing at the Fermi level which attributes massless Fermion character to charge carriers as in graphene. However, all binary compounds are found to be semiconductor with band gaps depending on the constituent atoms. We present a method to reveal elastic constants of 2D honeycomb structures from the strain energy and calculate the Poisson's ratio as well as in-plane stiffness values. Preliminary results show that the nearly lattice matched heterostructures of ...

description: Hot corinos are compact regions around solar-mass protostellar objects that are very rich in interstellar complex organic molecules (iCOMs). They are believed to represent the very early phases of our Solar System's birth, which was very likely also characterized by rich organic chemistry. While most of the studied hot corinos are either isolated or born in a loose protocluster, our Sun was born in a densely packed star cluster, near massive stars whose ultraviolet radiation must have contributed to shaping the evolution of the surrounding environment. In addition, internal irradiation from energetic particles ($>$10 Mev), whose imprint is seen today in the products of short-lived radionuclides in meteoritic material, is also known to have occurred during the Solar System formation. How did all these conditions affect the chemistry of the proto-Sun and its surroundings is still an open question. To answer this question, we studied HOPS-108, the hot corino located in the protosolar analogue OMC-2 FIR4. The study was carried out with ALMA at 1.3mm with an angular resolution of $\sim$100 AU. We detected 11 iCOMs such as CH$_{3}$OH HCOOCH$_{3}$ and CH$_{3}$OCH$_{3}$. Our results can be summarized as follows: (1) an enhancement of HCOOCH3 with respect to other hot corinos, (2) a [CH$_{3}$OCH$_{3}$]/[HCOOCH$_{3}$] abundance ratio of $\sim$0.2 marginally deviating from the usual trend seen in other sources ([CH$_{3}$OCH$_{3}$]/[HCOOCH$_{3}$] $\sim$1), (3) a [CH$_{2}$DOH]/[CH$_{3}$OH] ratio of 2.5\% which is lower than what is seen in Perseus and Ophiuchus hot corinos ($\sim$7\%-9\%) and similar to that seen in HH212 another source located in Orion. This might result from different physical conditions in the Orion molecular complex compared to other regions.

description: Urban areas are inherently noisy, and this noise can disrupt biological processes as diverse as communication, migration, and reproduction. We investigated how exposure to urban noise affects sleep, a process critical to optimal biological functioning, in Australian magpies (Cracticus tibicen). Eight magpies experimentally exposed to noise in captivity for 24-h spent more time awake, and less time in non-rapid eye movement (non-REM) and REM sleep at night than under quiet conditions. Sleep was also fragmented, with more frequent interruptions by wakefulness, shorter sleep episode durations, and less intense non-REM sleep. REM sleep was particularly sensitive to urban noise. Following exposure to noise, magpies recovered lost sleep by engaging in more, and more intense, non-REM sleep. In contrast, REM sleep showed no rebound. This might indicate a long-term cost to REM sleep loss mediated by noise, or contest hypotheses regarding the functional value of this state. Overall, urban noise has extensive, disruptive impacts on sleep composition, architecture, and intensity in magpies. Future work should consider whether noise-induced sleep restriction and fragmentation have long-term consequences.

description: In recent years it has been speculated that in extreme low metallicity galactic environments, stars form in regions that lack H2. In this paper we investigate how changing the metallicity and UV-field strength of a galaxy affects the star formation within, and the molecular gas Kennicutt-Schmidt relation. Using extremely high resolution arepo simulations of isolated dwarf galaxies, we independently vary the metallicity and UV-field to between 1% and 10% solar neighbourhood values. We include a non-equilibrium, time-dependant chemical network to model the molecular composition of the ISM, and include the effects of gas shielding from an ambient UV field. Crucially our simulations directly model the gravitational collapse of gas into star-forming clumps and cores and their subsequent accretion using sink particles. In this first publication we find that reducing the metallicity and UV-field by a factor of 10 has no effect on star formation, and minimal effect on the cold, dense star forming gas. The cold gas depletion times are almost an order of magnitude longer than the molecular gas depletion time due to the presence of star formation in HI dominated cold gas. We study the H2 Kennicutt-Schmidt relationship that arises naturally within the simulations and find a near linear power law index of N = 1.09 +/- 0.014 in our fiducial 10% solar metallicity model. As the metallicity and UV-field are reduced this becomes moderately steeper, with a slope of N = 1.24 +/- 0.022 for our 1% solar metallicity and 1% solar UV field model.

Passioni, ragione e motivazione nel Trattato di Hume

description: According to some critics, Hume cannot be considered a ‘humean’. In this paper arguments are presented to show that Hume, in the Treatise, supports the fundamental assumptions of a ‘humean’ theory of motivation, but doesn’t maintain a desirebased theory of justifying reasons. This doesn’t imply he’s a skeptic about practical reason. Trough the development of an original theory of ‘calm’ and ‘violent’ passions, Hume provides a naturalistic account of the origin and motivational influence of normative reasons.

Adiabatic quantum computation along quasienergies

description: The parametric deformations of quasienergies and eigenvectors of unitary operators are applied to the design of quantum adiabatic algorithms. The conventional, standard adiabatic quantum computation proceeds along eigenenergies of parameter-dependent Hamiltonians. By contrast, discrete adiabatic computation utilizes adiabatic passage along the quasienergies of parameter-dependent unitary operators. For example, such computation can be realized by a concatenation of parameterized quantum circuits, with an adiabatic though inevitably discrete change of the parameter. A design principle of adiabatic passage along quasienergy is recently proposed: Cheon's quasienergy and eigenspace anholonomies on unitary operators is available to realize anholonomic adiabatic algorithms [Tanaka and Miyamoto, Phys. Rev. Lett. 98, 160407 (2007)], which compose a nontrivial family of discrete adiabatic algorithms. It is straightforward to port a standard adiabatic algorithm to an anholonomic adiabatic one, except an introduction of a parameter |v>, which is available to adjust the gaps of the quasienergies to control the running time steps. In Grover's database search problem, the costs to prepare |v> for the qualitatively different, i.e., power or exponential, running time steps are shown to be qualitatively different. Curiously, in establishing the equivalence between the standard quantum computation based on the circuit model and the anholonomic adiabatic quantum computation model, it is shown that the cost for |v> to enlarge the gaps of the eigenvalue is qualitatively negligible.

description: Introduction

Pregnancy Toxaemia is a common pre-parturient metabolic disorder of small ruminants characterised by hypoglycaemia and hyperketonaemia in last few weeks of pregnancy (about 2-3 weeks before parturition). Pregnancy Toxaemia is characterized by nervous and toxaemic signs followed by death of pregnant doe with twins or triplets or quadruplets, which is a huge economic loss to the farmer. The incidence of Pregnancy Toxaemia is more common in sheep associated with high morbidity and mortality than goat.

Synonyms – Pregnancy Ketosis, Gestational Toxemia, Kidding sickness, Ovine Ketosis, Twin lamb disease (later terms of used for sheep).

description: We find topological (charged) black holes whose horizon has an arbitrary constant scalar curvature $2k$ in Hořava-Lifshitz theory. Without loss of generality, one may take $k=1,0$ and -1. The black hole solution is asymptotically AdS with a nonstandard asymptotic behavior. Using the Hamiltonian approach, we define a finite mass associated with the solution. We discuss the thermodynamics of the topological black holes and find that the black hole entropy has a logarithmic term in addition to an area term. We find a duality in Hawking temperature between topological black holes in Hořava-Lifshitz theory and Einstein's general relativity: the temperature behaviors of black holes with $k=1, 0$ and -1 in Hořava-Lifshitz theory are respectively dual to those of topological black holes with $k=-1, 0$ and 1 in Einstein's general relativity. The topological black holes in Hořava-Lifshitz theory are thermodynamically stable.

Expressed needs of women having abortions
Creators: name: McKay, Reta Lynn
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to explore the abortion experience from the woman's point of view to discover any unmet needs. All the women were having abortions within twelve weeks of their last menstrual period. The study included interviews with nineteen women at three stages: before the operation, two weeks following, and four months following the operation. A basically unstructured, open-ended interview method was used, allowing for exploration of areas important to the women. Referrals to the study were made by (1) a lay women's health education and abortion referral group, and (2) a gynecologist. The findings were described using frequencies of categories arising from the data. 1 The results of this study suggest that some women having abortions do experience unmet needs. The most common needs identified were: 1. the need for thorough discussion of birth control options coupled with discussion of sexuality; 2. the need for readily available information about all aspects of abortion; 3. the need for abortion counselling, including discussion of alternatives to abortion; 4. the need for emotional support during hospitalization and, possibly, afterwards; 5. the need to explore the meaning of this event within the context of the woman's life, in terms of her expectations of herself and her relationships with others. At the time of the third interview, many of the women described changes in their sexual relationships related to increased feelings of control and determination. The consistency between the developed recognition of sexuality and use of reliable contraception was evident in twelve of the fifteen women seen at that time. This interview revealed that all of the women felt they had made the best decision at the time, but four said they could not go through with an abortion again. The event was profoundly disturbing to their philosophical beliefs. This aspect of the women's lives is not a need of the same order as the others; rather, it is an area to be understood and appreciated, but not subject to specific Intervention. This study has identified, from a small sample, certain unmet needs experienced by abortion patients. Areas which require further research, involving larger numbers, centre around the following questions: 1. What are the most effective ways of meeting the identified needs of women having abortions? 2. What are the longer range effects on a woman's ability to cope with the abortion, and on her life generally, of meeting these needs?
Encoding Individual Source Sequences for the Wiretap Channel

Year: 2021
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: We consider the problem of encoding a deterministic source sequence (a.k.a.\ individual sequence) for the degraded wiretap channel by means of an encoder and decoder that can both be implemented as finite--state machines. Our first main result is a necessary condition for both reliable and secure transmission in terms of the given source sequence, the bandwidth expansion factor, the secrecy capacity, the number of states of the encoder and the number of states of the decoder. Equivalently, this necessary condition can be presented as a converse bound (i.e., a lower bound) on the smallest achievable bandwidth expansion factor. The bound is asymptotically achievable by Lempel-Ziv compression followed by good channel coding for the wiretap channel. Given that the lower bound is saturated, we also derive a lower bound on the minimum necessary rate of purely random bits needed for local randomness at the encoder in order to meet the security constraint. This bound too is achieved by the same achievability scheme. Finally, we extend the main results to the case where the legitimate decoder has access to a side information sequence, which is another individual sequence that may be related to the source sequence, and a noisy version of the side information sequence leaks to the wiretapper.

Faith and Renunciation in Early Buddhism: Saddhā and Nekkhamma

description: As a part of a study on faith and renunciation in the Buddhist Nikāyas, this article focuses on the dyad saddhā-nekkhamma. Through a semantic investigation, it is possible to see that the quality of saddhā, being strongly related to wisdom and mindfulness, is considered in the Pāli formulas as a support of the whole meditative path. It is not a matter of belief in a dogma, but indeed an ability to recognize the dangers of defilements and the opportunity to overcome them through the development of the mind. Nekkhamma is the active side of saddhā. By trusting the wider perspective taught by the Buddha, the individual can let go of the fetters that condition the mind: nekkhamma is renunciation of the habitual structure of self.

description: We apply statistical physics to study the task of resource allocation in random networks with limited bandwidths along the transportation links. The mean-field approach is applicable when the connectivity is sufficiently high. It allows us to derive the resource shortage of a node as a well-defined function of its capacity. For networks with uniformly high connectivity, an efficient profile of the allocated resources is obtained, which exhibits features similar to the Maxwell construction. These results have good agreements with simulations, where nodes self-organize to balance their shortages, forming extensive clusters of nodes interconnected by unsaturated links. The deviations from the mean-field analyses show that nodes are likely to be rich in the locality of gifted neighbors. In scale-free networks, hubs make sacrifice for enhanced balancing of nodes with low connectivity.

Il ruolo delle immagini sensibili nella dottrina della conoscenza profetica di Alberto Magno
Creators: name: Rodolfi, Anna
Publisher: name: Annali del Dipartimento di Filosofia
Year: 2005

description: Medieval philosophers who wrote about prophecy were influenced by Aristotelian theory of soul. Aristotle stated that understanding owes to imagination the materials of its knowledge, i.e. sensible images or phantasmata. Without images there isn’t any thought: does this Aristotelian axiom fit to prophetical knowledge, too? Prophetical knowledge, even if it is supernatural, actually does not take place without sensible images, just like any other natural knowledge. Which function do such images play within prophetical knowledge? In his Quaestio de prophetia, Albert the Great tries to answer this question. His original solution consists in claiming that sensible images do play a positive function in regard to prophecy.

description: It is remarkable how the Froehlich polaron, one of the simplest examples of a Quantum Field Theoretical problem, as it basically consists of a single fermion interacting with a scalar Bose field of ion displacements, has resisted full analytical or numerical solution at all coupling since 1950, when its Hamiltonian was first written. The field has been a testing ground for analytical, semi-analytical, and numerical techniques, such as path integrals, strong-coupling perturbation expansion, advanced variational, exact diagonalisation (ED), and quantum Monte Carlo (QMC) techniques. This article reviews recent developments in the field of continuum and discrete (lattice) Froehlich (bi)polarons starting with the basics and covering a number of active directions of research.

Urban land development : political process, and the local area: comparative study of Kitsilano and Grandview-Woodlands
Creators: name: Jensen, Jens Christian
Publisher: name: University of British Columbia
Year: 2010

description: The political context of citizen participation in North American governments since World War II has largely been one of failure of non-elites to influence governments at all levels to accommodate their values and interests. Among concepts of government designed to facilitate the political efficacy cf such groups is that of decentralization of some powers of municipal government to the "neighborhood" or local area level in large cities. Municipal decentralization theory rests on assumptions that common interests can be identified with a definable local area and that political processes at that level reflect local political values and interests. The general hypothesis was that political processes in local areas reflect the diversity of political values and interests of the local area population and thus have the potential to legitimize decision-making at that level. Review of literature on democratic theory led to a postulate that a political process which reflects a constituency's values and interests is pluralistic and is perceived to be legitimate by political actors. It was also postulated that lines of political cleavage in the urban land development control issue area, the issue area chosen for this research, would follow social class lines. Working hypotheses were constructed based on the above two postulates and a definition of "legitimacy" of government. The general hypothesis was sustained by a limited comparative study of local area political processes in the Kitsilano and Grandview-Woodlands local areas of Vancouver, by study of one politically salient site-specific land development control issue in each. A combination of decisional and reputational techniques was used to identify influential political actors at the local area level and to identify key events. A qualification was observed in political actors' perception of legitimacy of a hypothetical local area government with some powers in land development control: the electoral process was perceived by most tc be an inadequate instrument of citizen control of government at that level. It was concluded that further research was warranted in means of facilitating political integration at the local area level, as existing community councils did not perform that function in the issues studied.
Assessing the incidence and wage effects of overeducation among Italian graduates using a new measure for educational requirements

description: This paper investigates three dimensions of overeducation: incidence, impact on earnings and possible determinants.
The analysis focuses on Italian graduates and refers to the cohort that graduated in 2007 using data from the
AlmaLaurea survey on graduates' career paths. A new measure of overeducation is introduced and it is jointly
examined along with other pre-existing measures based on workers' self-assessment. The analysis is carried out by
comparing the different results obtained adopting the two different measures of overeducation. Results show that the
newly introduced measure can deal with the biases affecting workers' self- assessment measures.

description: Abstract

In this study the finite element method is used to analyse the distribution of failure stresses in circular aperture wire plates with different type of stiffener location. The stress distribution in the adhesive layer will be analysed to estimate the durability of the repair technique by varying the different stiffener parameter, this analysis allows the designers to optimise the location of the stiffener used for the repair of the structures, the results obtained showed the best locations of the stiffener used for the repair of the structures. This study provides a novel approach to optimizing stiffener locations in repair techniques, enhancing the durability and efficiency of structural repairs through detailed finite element analysis.
Strong stabilization of (almost) impedance passive systems by static output feedback

description: The plant to be stabilized is a system node $Σ$ with generating triple $(A,B,C)$ and transfer function $\bf G$, where $A$ generates a contraction semigroup on the Hilbert space $X$. The control and observation operators $B$ and $C$ may be unbounded and they are not assumed to be admissible. The crucial assumption is that there exists a bounded operator $E$ such that, if we replace ${\bf G}(s)$ by ${\bf G}(s)+E$, the new system $Σ_E$ becomes impedance passive. An easier case is when $\bf G$ is already impedance passive and a special case is when \mm $Σ$ has colocated sensors and actuators. Such systems include many wave, beam and heat equations with sensors and actuators on the boundary. It has been shown for many particular cases that the feedback $u=-κy+v$, where $u$ is the input of the plant and $κ>0$, stabilizes $Σ$, strongly or even exponentially. Here, $y$ is the output of \m $Σ$ and $v$ is the new input. Our main result is that if for some $E\in{\mathcal L}(U)$, $Σ_E$ is impedance passive, and \m $Σ$ is approximately observable or approximately controllable in infinite time, then for sufficiently small $κ$ the closed-loop system is weakly stable. If, moreover, $σ(A)\cap i{\mathbb R}$ is countable, then the closed-loop semigroup and its dual are both strongly stable.

description: In this paper we propose a microscopic model to study the polymerization of microtubules (MTs). Starting from fundamental reactions during MT's assembly and disassembly processes, we systematically derive a nonlinear system of equations that determines the dynamics of microtubules in 3D. %coexistence with tubulin dimers in a solution. We found that the dynamics of a MT is mathematically expressed via a cubic-quintic nonlinear Schrodinger (NLS) equation. Interestingly, the generic 3D solution of the NLS equation exhibits linear growing and shortening in time as well as temporal fluctuations about a mean value which are qualitatively similar to the dynamic instability of MTs observed experimentally. By solving equations numerically, we have found spatio-temporal patterns consistent with experimental observations.

description: We present the first statistical analysis of 27 UVOT optical/ultra-violet lightcurves of GRB afterglows. We have found, through analysis of the lightcurves in the observer's frame, that a significant fraction rise in the first 500s after the GRB trigger, that all lightcurves decay after 500s, typically as a power-law with a relatively narrow distribution of decay indices, and that the brightest optical afterglows tend to decay the quickest. We find that the rise could either be produced physically by the start of the forward shock, when the jet begins to plough into the external medium, or geometrically where an off-axis observer sees a rising lightcurve as an increasing amount of emission enters the observers line of sight, which occurs as the jet slows. We find that at 99.8% confidence, there is a correlation, in the observed frame, between the apparent magnitude of the lightcurves at 400s and the rate of decay after 500s. However, in the rest frame a Spearman Rank test shows only a weak correlation of low statistical significance between luminosity and decay rate. A correlation should be expected if the afterglows were produced by off-axis jets, suggesting that the jet is viewed from within the half-opening angle theta or within a core of uniform energy density theta_c. We also produced logarithmic luminosity distributions for three rest frame epochs. We find no evidence for bimodality in any of the distributions. Finally, we compare our sample of UVOT lightcurves with the XRT lightcurve canonical model. The range in decay indices seen in UVOT lightcurves at any epoch is most similar to the range in decay of the shallow decay segment of the XRT canonical model. However, in the XRT canonical model there is no indication of the rising behaviour observed in the UVOT lightcurves.

description: The aim of my paper is to present the formal aspects and developments of Rational Choice Theory referring to its main theorems and demonstrations. I will argue for the existence of two distinctive limits of the RCT: an intrinsic limit, represented by a logical contradiction between the axioms of the theory and its social extension (Harsanyi Theorem), and an extrinsic limit, represented by the empirical objections to the very axioms of the RCT (Kahneman and Tversky’s Cumulative Prospect Theory).
