description: The species originally attributed by Airoldi (1932) to the genus Lithophyllum (L. perrandoi, L. ligusticum, L. personatum and L. desitum) are here re-examined on the basis of the original material, original descriptions and illustrations. L. perrandoi and L. ligusticum are considered to be conspecific and questionably retained in the genus Lithophyllum. We give priority to the name ?L. perrandoi Airoldi to honour the priest Don Perrando, who collected most of the fossils conserved in the Dip.Te.Ris of Genova. L. personatum and L. desitum do not belong to the genus Lithophyllum as presently circumscribed. L. personatum Airoldi is a female/carposporangial plant of a mastophoroid species resembling Spongites fruticulosus Kützing, and therefore we retain a dubitative identification with the new combination ?Spongites personatus (Airoldi). L. desitum is here placed in the genus Mesophyllum under the new combination Mesophyllum desitum (Airoldi). On the basis of its vegetative and reproductive features, M. desitum comb. nov. is here considered conspecific with Mesophyllum obsitum Airoldi. Pdf

description: In the basis where the charged lepton mass matrix is diagonal, the left-handed neutrino mass matrix is invariant under the permutation of the second and third generations if, and only if, the reactor angle $θ_{13}$ is zero and the atmospheric mixing angle $θ_{23}$ is maximal. In the presence of the seesaw mechanism, this symmetry leads to an inverted hierarchy, with $m_3=0$. This inverted mass spectrum is doubly protected if the right-handed neutrinos also have a 2-3 symmetry.

description: We consider the number of Bowen sets which are necessary to cover a large measure subset of the phase space. This introduce some complexity indicator characterizing different kind of (weakly) chaotic dynamics. Since in many systems its value is given by a sort of local entropy, this indicator is quite simple to be calculated. We give some example of calculation in nontrivial systems (interval exchanges, piecewise isometries e.g.) and a formula similar to the Ruelle-Pesin one, relating the complexity indicator to some initial condition sensitivity indicators playing the role of positive Lyapunov exponents.

description: We present the discovery of TOI 540 b, a hot planet slightly smaller than Earth orbiting the low-mass star 2MASS J05051443-4756154. The planet has an orbital period of $P = 1.239149$ days ($\pm$ 170 ms) and a radius of $r = 0.903 \pm 0.052 R_{\rm Earth}$, and is likely terrestrial based on the observed mass-radius distribution of small exoplanets at similar insolations. The star is 14.008 pc away and we estimate its mass and radius to be $M = 0.159 \pm 0.014 M_{\rm Sun}$ and $R = 0.1895 \pm 0.0079 R_{\rm Sun}$, respectively. The star is distinctive in its very short rotational period of $P_{\rm rot} = 17.4264 +/- 0.0094$ hours and correspondingly small Rossby number of 0.007 as well as its high X-ray-to-bolometric luminosity ratio of $L_X / L_{\rm bol} = 0.0028$ based on a serendipitous XMM-Newton detection during a slew operation. This is consistent with the X-ray emission being observed at a maximum value of $L_X / L_{\rm bol} \simeq 10^{-3}$ as predicted for the most rapidly rotating M dwarfs. TOI 540 b may be an alluring target to study atmospheric erosion due to the strong stellar X-ray emission. It is also among the most accessible targets for transmission and emission spectroscopy and eclipse photometry with JWST, and may permit Doppler tomography with high-resolution spectroscopy during transit. This discovery is based on precise photometric data from TESS and ground-based follow-up observations by the MEarth team.

description: The photochemical haze produced in the upper atmosphere of Titan plays a key role in various atmospheric and surface processes on Titan. The surface energy, one important physical properties of the haze, is crucial for understanding the growth of the haze particles and can be used to predict their wetting behavior with solid and liquid species on Titan. We produced Titan analog haze materials, so-called "tholin", with different energy sources and measured their surface energies through contact angle and direct force measurements. From the contact angle measurement, we found that the tholins produced by cold plasma and UV irradiation have total surface energy around 60-70 mJ/m2. The direct force measurement yields a total surface energy of ~66 mJ/m2 for plasma tholin. The surface energy of tholin is relatively high compared to common polymers, indicating its high cohesiveness. Therefore, the Titan haze particles would likely coagulate easily to form bigger particles, while the haze-derived surface sand particles would need higher wind speed to be mobilized because of the high interparticle cohesion. The high surface energy of tholins also makes them easily wettable by Titan's atmospheric hydrocarbon condensates and surface liquids. Thus, the hazes particles are likely good cloud condensation nuclei (CCN) for hydrocarbon clouds (methane and ethane) to nucleate and grow. And if the hazes particles are denser compared to the lake liquids, they would likely sink into the lakes instead of forming a floating film to dampen the lake surface waves.

Partial characterization of a putative transcriptional regulator of the 4CL1 gene
Creators: name: Jones, Jennifer Anne
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is intended to further our understanding of the mechanisms by which expression of phenylpropanoid genes, specifically parsley 4-coumarate : CoA ligase (4CL1), are developmental^ regulated. The 4CL enzyme is the third and final step in the core phenylpropanoid metabolic pathway. 4CL1-GUS fusions are specifically expressed in the xylem and floral organs in transgenic tobacco. In-vivo footprinting and sitedirected mutagenesis revealed a region spanning -78 to -120, known as footprint 56, of the 4CL1 promoter which is critical for 4CL expression. DNasel footprinting and gel shift assays using tobacco nuclear extracts indicated that a nuclear factor or complex of factors bind to this cis-element on the 4CL1 promoter in vitro. A putative transcription factor which binds to this footprint 56, termed 56BF, was isolated by using a footprint 56 oligonucleotide as a probe to screen a tobacco cDNA expression library. To test whether 56BF is involved in regulating expression of the 4CL1 gene, transgenic tobacco plants that over-expressed or were suppressed for its' accumulation were generated. 56BF recombinant protein was expressed in E. Coli to test the DNA-binding specificity of the protein. Results discussed in this thesis strongly suggest that 56BF does not regulate the 4CL1 gene in vivo.

description: The Lower Permian Hueco Group of the Doña Ana Mountains (south-central New Mexico, USA) is studied in three sections (A, B, C) located east of Leasburg, Doña Ana County. Regionally, the Hueco Group has been subdivided into four formations termed Shalem Colony, Community Pit, Robledo Mountains and Apache Dam formations; the lower three are exposed in the Doña Ana Mountains. The succession shows a shallowing upward trend from dominantly shallow, open marine conditions (Shalem Colony Fm) to increasingly restricted marine environments (Community Pit Fm) and siliciclastic influx (Robledo Mountains Formation). Sedimentation, particularly siliciclastic influx, was mainly controlled by reactivation of basement uplifts during the last pulses of the Ancestral Rocky Mountains deformation. The microfossils and microfacies of the two first formations are studied in detail here. The Shalem Colony Formation can be divided into a lower biozone with Triticites pinguis, which is Newwellian (latest Pennsylvanian, early Wolfcampian) in age, and an upper division characterized by the first occurrence of Geinitzina, and lower-middle Asselian (late early Wolfcampian) in age. By comparison with the subdivisions of the Carnic Alps (Austria), the Community Pit Formation is characterized as Sakmarian (middle Wolfcampian) in age due to the first occurrence of the genus Pseudovermiporella, and its probable complete phylogeny from Hedraites. The late Asselian is restricted to the uppermost part of the Shalem Colony and lowermost part of the Community Pit Formation. Due to the occurrence of Pseudoreichelina the Robledo Mountains Formation is dated as Artinskian (late Wolfcampian). Some bioconstructions of Archaeolithophyllum are emphasized, as well as some species of foraminifers-globivalvulinids, Miliolata and Nodosariata.

Core Overshoot: An Improved Treatment and Constraints from Seismic Data

description: We present a comprehensive set of stellar evolution models for Procyon A in an effort to guide future measurements of both traditional stellar parameters and seismic frequencies towards constraining the amount of core overshoot in Procyon A and possibly other stars. Current observational measurements of Procyon A when combined with traditional stellar modeling only place a large upper limit on overshoot of alphaOV < 1.1. By carrying out a detailed pulsation analysis, we further demonstrate, how p- and g-mode averaged spacings can be used to gain better estimates of the core size. For both p- and g-modes, the frequency spacings for models without overshoot are clearly separated from the models with overshoot. In addition, measurements of the l=0 averaged small p-mode spacings could be used to establish Procyon A's evolutionary stage. For a fixed implementation of overshoot and under favorable circumstances, the g-mode spacings can be used to determine the overshoot extent to an accuracy of +-0.05 Hp. However, we stress that considerable confusion is added due to the unknown treatment of the overshoot region. This ambiguity might be removed by analyzing many different stars. A simple non-local convection theory developed by Kuhfuss is implemented in our stellar evolution code and contrasted with the traditional approaches. We show that this theory supports a moderate increase of the amount of convective overshoot with stellar mass of Delta(alphaOV) = +0.10 between 1.5 Msun and 15 Msun. This theory places an upper limit on Procyon A's core overshoot extent of ~0.4 Hp which matches the limit imposed by Roxburgh's integral criterion.

description: Early Permian (Sakmarian) crinoids are described from six horizons in the Saiwan Formation of the Huqf area of southeastern Oman. Each horizon yielded only one to three taxa. All specimens lived in a shallow water environment characterized by mixed siliciclastic or siliciclastic-carbonate sedimentation. Disarticulated arm plates of an indeterminate articulate crinoid are described from a tempestite bed in the Khuff Formation (Wordian) of the Haushi area.
The Saiwan Sakmarian crinoids are some of the earlier, although not the earliest Permian crinoids known. Representatives of both primitive (sycocrinids) and advanced (scytalocrinids, blothrocrinids, texacrinids, and cromyocrinids) cladids and articulates are present in the Saiwan crinoids that are dominated by advanced dendrocrinids and belong to families previously reported from the Carboniferous or Permian. They show greatest affinity to the late Sakmarian/early Artinskian fauna from the Callytharra Formation of Western Australia.
New taxa described herein double the number of genera (three) previously reported from the same area. The diversity of the Saiwan crinoids is relatively low when compared to the large faunas reported from Timor, Western Australia, Russia, and North America. However, they show affinity with each of the larger faunas.  New taxa described are Coeliocrinus arenaceous n. sp., Moapacrinus? omanensis n. sp., Huqficrinus biserialis n. gen. and sp., and Campbellicrinus nodosus n. sp.

description: Carbonaceous nano-grains are present at the surface of protoplanetary disks around Herbig Ae/Be stars, where most of the central star UV energy is dissipated. Efficiently coupled to the gas, nano-grains are able to trace the disk outer flaring parts, and possibly the gaps from which the larger grains are missing. We examine the spatial distribution and evolution of the nano-dust emission in the (pre-)transitional disk HD100546 that shows annular gaps, rings, and spirals, and reveals rich carbon nano-dust spectroscopic signatures (aromatic, aliphatic) in a wide spatial range (~20-200au). We analyse adaptive optics spectroscopic observations from 3 to 4um and imaging and spectroscopic observations from 8 to 12um. We compare the data to model predictions using the THEMIS model with the radiative transfer code POLARIS calculating heating of micro- and nanometric dust grains for a given disk structure. The aromatic features at 3.3, 8.6 and 11.3um, as well as, the aliphatic ones from 3.4 to 3.5um are spatially extended with band morphologies dependong on local physical conditions. The aliphatic-to-aromatic band ratio 3.4/3.3 increases with the distance from the star suggesting UV processing. In the 8-12um observed spectra, features characteristic of aromatic particles and crystalline silicates are detected with their relative contribution changing with distance to the star. The model predicts that the features and adjacent continuum are due to different combinations of grain sub-populations, with a dependence on the UV field intensity. Shorter wavelength features are dominated by the smallest grains (< 0.7nm) throughout the disk, while at longer wavelengths what dominates the emission close to the star is a mix of several grain populations, and far away from the star is the largest nano-grain population.

description: The Cretaceous species of the coral genus Diplocoenia are revised, mainly on the basis of sample material. This genus is characterised by polygonal calices in a cerioid arrangement, compact septa in a regular symmetry and a dissepimental ring with the appearance of a second inner wall. Of the 18 Cretaceous species reported in the literature, five are confirmed, four are synonyms and nine do not belong to this genus. The species with the widest geographic and stratigraphic distribution is Diplocoenia dollfusi Prever, 1909, originally described from the Monti d’Ocre complex in the Abruzzi region. The genus occurs in the Cretaceous only in the central Tethys and in the Boreal, and ranges from the Middle Jurassic to the Aptian (?early Albian). Only about 50 samples from the Cretaceous exist or are known from the literature, making Diplocoenia rather rare in the Cretaceous.

description: Given a location-based social network, how to find the communities that are highly relevant to query users and have top overall scores in multiple attributes according to user preferences? Typically, in the face of such a problem setting, we can model the network as a multi-attributed road-social network, in which each user is linked with location information and $d$ ($\geq\! 1$) numerical attributes. In practice, user preferences (i.e., weights) are usually inherently uncertain and can only be estimated with bounded accuracy, because a human user is not able to designate exact values with absolute precision. Inspired by this, we introduce a normative community model suitable for multi-criteria decision making, called multi-attributed community (MAC), based on the concepts of $k$-core and a novel dominance relationship specific to preferences. Given uncertain user preferences, namely, an approximate representation of weights, the MAC search reports the exact communities for each of the possible weight settings. We devise an elegant index structure to maintain the dominance relationships, based on which two algorithms are developed to efficiently compute the top-$j$ MACs. The efficiency and scalability of our algorithms and the effectiveness of MAC model are demonstrated by extensive experiments on both real-world and synthetic road-social networks.

description: A continuous late Eocene through Oligocene carbonate sequence was recovered at Ocean Drilling Program (ODP) Site 1218 in the paleo-equatorial Pacific Ocean. The preservation history of selected calcareous nannofossil species across the Eocene/Oligocene (E/O) boundary is presented together with late Eocene and Oligocene calcareous nannofossil biochronology. The astronomically calibrated timescale of Pälike et al. (2006) is used here. Across the E/O boundary, placolith preservation is controlled by variation in carbonate content. Taxa less prone to dissolution are Reticulofenestra  umbilicus, Coccolithus  pelagicus, Ericsonia formosa and Dictyococites bisectus, while Cyclicargolithus floridanus is more susceptible to dissolution. A biochronologic framework has been established for the following taxa: the highest occurrences (HO) of Discoaster barbadiensis (34.773 Ma), D. saipanensis (34.435 Ma), E. formosa (32.919 Ma), R. umbilicus (32.021 Ma), Sphenolithus predistentus (26.928 Ma), S. distentus (26.812 Ma), and S. ciperoensis (24.432 Ma), and the lowest occurrences (LO) of S. distentus (29.997 Ma) and S. ciperoensis (27.142 Ma). The first consistent appearance of Triquetrorhabdulus carinatus occurs at 26.556 Ma, while the onset of the peak interval of T. carinatus was determined at 24.669 Ma. Biochronological comparisons are made with other sites from the Atlantic Ocean. A Triquetrorhabdulus morphotype, labeled as T. aff. carinatus, was recorded for the first time in the studied sediments, and precedes the LO of T. carinatus by ~ 0.7 Myr. Its stratigraphic range has a duration of about 3.3 Myr. T. aff. carinatus disappears concomitantly with the beginning of a sharp increase in abundance of T. carinatus.

description: Despite their increasing importance in sedimentology and palaeoecology, non-geniculate coralline algae remain virtually overlooked in Slovenia. Though these plants are present or even abundant in the Cretaceous and Cainozoic strata, they have never been studied in detail with notable exception of corallines from the Lower Oligocene beds in the area of Gornji Grad. Poljšica pri Podnartu is another locality where Lower Oligocene beds are exposed, considered as equivalent to the former. The studied profile consists of pebbly limestone, mudstone, sandstone and limestone. Limestones contain abundant non-geniculate coralline algae. Nine species from six genera of these corallines have been identified: Lithoporella melobesioides (Foslie) Foslie, 1909, Neogoniolithon contii (Mastrorilli) Quaranta et al., 2007, Spongites sp., Lithothamnion sp. 1, Lithothamnion sp. 2, Mesophyllum sp. 1, Mesophyllum sp. 2, Mesophyllum sp. 3 and Sporolithon sp. Some of these species are described from Slovenia for the first time.

We consider next the three strings vertex coefficients of the light--cone string field theory on a maximally supersymmetric pp--wave background. Using the previous results we are able to show that these Neumann coefficients satisfy the Hirota equations for the full Toda lattice hierarchy at least up to second order in the 'string mass' $μ$.

description: The echinoid Parascutella gibbercula (de Serres, 1829) (Echinoidea: Clypeasteroida) is reported from the Mali Potok area of the Medvednica Mountain in Croatia. The fossil site is situated in mixed siliciclastics and biocalcarenites of late Badenian age. These echinoids are large extremely flat echinoids, informally known as sand dollars. The discovered echinoids are preserved in situ. The environment of deposition is defined as a shallow, coastal, high-energy environment for which these sea-urchins have developed characteristic morphological features. The strength and hydrodynamic stability of their shells enabled the post-mortal colonisation of the skeleton by epibenthic organisms, creating a robust, relatively stable substrate within otherwise mobile, unconsolidated sediments (secondary hardground). The Mali Potok echinoid assemblage has an unusual taxonomic composition for the Late Miocene of Croatia.

description: We investigate nonanalyticities (e.g., zeros and poles) of refractive index $n(ω)$ and group index $n_g(ω)$ in different optical setups. We first demonstrate that: while a Lorentzian dielectric has no nonanalyticity in the upper half of the complex frequency plane (CFP), its group index -- which governs the pulse-center propagation -- violates the Kramers-Kronig relations (KKRs). Thus, we classify the nonanalyticities as in the (a) first-order (refractive index or reflection) and (b) second-order (group index or group delay). The latter contains the derivative of the former. Then, we study a possible connection between the negative superluminal velocities and the presence of nonanalyticities in the upper half of the CFP. We show that presence of nonanalyticities in the upper half of the CFP for (a) the first-order response and (b) the second-order response are accompanied by the appearance of negative (a) phase velocity and (b) group velocity, respectively. We also distinguish between two kinds of superluminosity, $v>c$ and $v<0$, where we show that the second one ($v<0$) appears with the violation of KKRs.

description: The biochron of the subfamily Megatheriinae, large to very large terrestrial sloths typified by Megatherium Cuvier, in Argentina extends from the middle Miocene of Patagonia to the late Pleistocene-early Holocene. Megatheriines reached their highest diversity in the lower levels (="conglomerado osífero", late Miocene) of the Ituzaingó Formation in Entre Ríos Province, northeastern Argentina. Among the four megatheriines that occur in this unit, the genera Promegatherium Ameghino, Eomegatherium Kraglievich and Pliomegatherium Kraglievich represent relatively small to medium-sized taxa. Here we describe new material assigned to Pyramiodontherium, the largest of the four genera from the same bed and comparable in size to some Quaternary species of Megatherium. Three valid species of Pyramiodontherium have been recognized, all distributed mainly in northwestern Argentina, from the late Miocene in Catamarca Province (and probably also in Tucumán Province), and the late Pliocene in La Rioja Province. The presence of this genus in northeastern Argentina extends its known paleobiogeographical distribution.

description: A large number of hipparion skulls from Hadzhidimovo-1 (HD) are studied herein. The sample includes individuals of various ages that allow the investigator to study their ontogenetic development. Two species of hipparion are recognized, including Hippotherium brachypus Hensel, 1862 and Cremohipparion mediterraneum Roth & Wagner, 1855. A study of the lateral aspect of the face, including the maxillary and premaxillary regions were made with specific attention paid to the placement of the preorbital and subnasal (= intermediate) fossae. The morphology of these structures are found to be of taxonomic value.  This study reveals that the most intensive growth of the cheek region in both species is the period during which the maxillary M2 erupts and that the two species have different modes of ontogenetic changes in the location of preorbital fossa. During ontogeny, the preorbital fossa of Hippotherium brachypus migrates further from the orbit, while in the C. mediterraneum samples the preorbital fossa does not migrate - it remains stationary into and throughout adulthood. This study documents intraspecific variability in preorbital fossa morphology, throughout the ontogeny for both species of hipparion under consideration.

description: All one-loop renormalization constants for Non-Abelian gauge theory are computed in details by using the symmetry-preserving Loop Regularization method proposed in\cite{LR1,LR2}. The resulting renormalization constants are manifestly shown to satisfy Ward-Takahaski-Slavnov-Taylor identities, and lead to the well-known one loop $β$ function for Non-Abelian gauge theory of QCD\cite{GWP}. The loop regularization method is realized in the dimension of original field theories, it maintains not only symmetries but also divergent behaviors of original field theories with the introduction of two energy scales. Such two scales play the roles of characterizing and sliding energy scales as well as ultraviolet and infrared cutoff energy scales. An explicit Check of those identities provides a clear demonstration how the symmetry-preserving Loop Regularization method can consistently be applied to non-Abelian gauge theories.

description: The one-dimensional fall of a folded chain with one end suspended from a rigid support and a chain falling from a resting heap on a table is studied. Because their Lagrangians contain no explicit time dependence, the falling chains are conservative systems. Their equations of motion are shown to contain a term that enforces energy conservation when masses are transferred between subchains. We show that Cayley's 1857 energy nonconserving solution for a chain falling from a resting heap is incorrect because it neglects the energy gained when a transferred link leaves a subchain. The maximum chain tension measured by Calkin and March for the falling folded chain is given a simple if rough interpretation. Other aspects of this falling folded chain are briefly discussed.

description: Refactoring is the art of improving the design of a system without altering its external behavior. Refactoring has become a well established and disciplined software engineering practice that has attracted a significant amount of research presuming that refactoring is primarily motivated by the need to improve system structures. However, recent studies have shown that developers may incorporate refactorings in other development activities that go beyond improving the design. Unfortunately, these studies are limited to developer interviews and a reduced set of projects. To cope with the above-mentioned limitations, we aim to better understand what motivates developers to apply refactoring by mining and classifying a large set of 111,884 commits containing refactorings, extracted from 800 Java projects. We trained a multi-class classifier to categorize these commits into 3 categories, namely, Internal QA, External QA, and Code Smell Resolution, along with the traditional BugFix and Functional categories. This classification challenges the original definition of refactoring, being exclusive to improving the design and fixing code smells. Further, to better understand our classification results, we analyzed commit messages to extract textual patterns that developers regularly use to describe their refactorings. The results show that (1) fixing code smells is not the main driver for developers to refactoring their codebases. Refactoring is solicited for a wide variety of reasons, going beyond its traditional definition; (2) the distribution of refactorings differs between production and test files; (3) developers use several patterns to purposefully target refactoring; (4) the textual patterns, extracted from commit messages, provide better coverage for how developers document their refactorings.

description: Ένα από τα πιο κλασσικά προβλήματα στην Θεωρία Πιθανοτήτων και την Μαθηματική Στατιστική είναι το πρόβλημα καταστροφής παίκτη, όπου συμμετέχουν δύο παίκτες και η λύση του επιτυγχάνεται με σχετικά απλό τρόπο. Το πρόβλημα βρίσκει άμεση εφαρμογή στα Χρηματοοικονομικά. Ως επέκταση του προβλήματος, όταν οι παίκτες που συμμετέχουν στο παιχνίδι είναι περισσότεροι από δύο και οι πιθανότητες νίκης κάθε παίκτη σε κάθε στάδιο του παιχνιδιού δεν είναι αναγκαστικά ίσες, έχουμε να κάνουμε με το λεγόμενο ασύμμετρο πρόβλημα καταστροφής παίκτη με παίκτες ( ). Το γεγονός της άμεσης σχέσης των προβλημάτων αυτών με μία κλάση στοχαστικών διαδικασιών που ονομάζονται τυχαίοι περίπατοι, δε μας αφήνει αδιάφορους για αυτό και παρουσιάζουμε κάποια ενδιαφέροντα αποτελέσματα σχετικά με τους τυχαίους περίπατους. Για την περίπτωση όπου τα αρχικά κεφάλαια των παικτών είναι αυθαίρετα, δημιουργήσαμε έναν αλγόριθμο προσομοίωσης του παιχνιδιού στην γλώσσα S. Για τις περιπτώσεις όπου όλα τα αρχικά κεφάλαια των παικτών ισοδυναμούν με χρηματικές μονάδες, όπου εξάγουμε την αναμενόμενη τιμή ως την καταστροφή, την κατανομή του χρόνου αυτού στάσης, υπολογίζουμε τις πιθανότητες καταστροφής του παίκτη , καθώς και οποιουδήποτε συνδυασμού παικτών και αποδεικνύουμε ότι το ποιος ή ποιοι παίκτες καταστρέφονται και το πότε συμβαίνει η καταστροφή είναι ανεξάρτητα γεγονότα.
description: One of the most classical problems in Probability Theory and Mathematical Statistics is the gambler’s ruin problem in which take part two players and its solution is quite simple and well known. This problem has a clear and exact application in Finance. As an extension to this problem, we consider the case that three or more gamblers take part in the game and so we have to deal with the gambler’s ruin problem with players, and – in generally - asymmetric play. The fact that there is a direct relationship between these problems and a special class of stochastic processes called random walks, lead us to analyze and present some interesting results about random walks. We create and present an algorithm in programme language S that simulates the hole process of the game, for the case in which the initial capital of each player is an arbitrary integer. For the cases in which the initial fortune of each player is equal to a constant , with we derive a closed-form formula for the expected time until ruin, we compute the probability distribution of this stopping time, the probabilities that player is ruined, as well as the probabilities of ruin of any combination of players and we prove that which player or players are ruined and when ruin occurs are independent events..

description: We construct purely non-perturbative anti-de Sitter vacua in string theory which, on uplifting to a de Sitter (dS) one, have a decay time many orders of magnitude smaller than those of standard constructions, such as the KKLT and LVS scenarios. By virtue of being constructed purely from non-perturbative terms, these vacua avoids certain obstructions plaguing other constructions of dS in string theory. This results in a new class of phenomenological dS vacua in string theory with novel distinctive characteristics such as having two maxima. After examining whether these uplifted dS vacua obey the TCC, we revisit some old problems of realization of dS space as a vacuum. We find that not only is it phenomenologically hard to construct TCC-compatible vacua, but also inherent temporal dependences of the degrees of freedom generically arise in such constructions, amongst other issues. This reinforces the idea that dS, if it exists in string theory, should be a Glauber-Sudarshan state and not a vacuum.

description: Designing robust and accurate predictive models for stock price prediction has been an active area of research for a long time. While on one side, the supporters of the efficient market hypothesis claim that it is impossible to forecast stock prices accurately, many researchers believe otherwise. There exist propositions in the literature that have demonstrated that if properly designed and optimized, predictive models can very accurately and reliably predict future values of stock prices. This paper presents a suite of deep learning based models for stock price prediction. We use the historical records of the NIFTY 50 index listed in the National Stock Exchange of India, during the period from December 29, 2008 to July 31, 2020, for training and testing the models. Our proposition includes two regression models built on convolutional neural networks and three long and short term memory network based predictive models. To forecast the open values of the NIFTY 50 index records, we adopted a multi step prediction technique with walk forward validation. In this approach, the open values of the NIFTY 50 index are predicted on a time horizon of one week, and once a week is over, the actual index values are included in the training set before the model is trained again, and the forecasts for the next week are made. We present detailed results on the forecasting accuracies for all our proposed models. The results show that while all the models are very accurate in forecasting the NIFTY 50 open values, the univariate encoder decoder convolutional LSTM with the previous two weeks data as the input is the most accurate model. On the other hand, a univariate CNN model with previous one week data as the input is found to be the fastest model in terms of its execution speed.
