In platform videogames, players are frequently tasked with solving medium-term navigation problems in order to gather items or powerups. Artificial agents must generally obtain some form of direct experience before they can solve such tasks. Experience is gained either through training runs, or by exploiting knowledge of the game's physics to generate detailed simulations. Human players, on the other hand, seem to look ahead in high-level, abstract steps. Motivated by human play, we introduce an approach that leverages not only abstract "skills", but also knowledge of what those skills can and cannot achieve. We apply this approach to Infinite Mario, where despite facing randomly generated, maze-like levels, our agent is capable of deriving complex plans in real-time, without relying on perfect knowledge of the game's physics.

This study aims to examine the laws of dowry money decoration that are common in the community. The innovation and soul of art that is channeled through décor of dowry money is proven to produce beautiful and unique works, so as to attract the attention and interest of the wider community. However, because to produce beautiful and unique works, a high level of creativity is needed, so not everyone can do it. On the one hand, this phenomenon opens up quite good business opportunities, but on the other hand, it should be watched out, because in some conditions it contains the practice of buying and selling currencies with nominal differences. Through this study, I would like to uncover the law of buying and selling practices decorating dowry money and decorating services. As I also intend to present an applicative solution for the community so that they can still channel their artistic talents without violating Shari’ah law.

We show that, for automata using a finite number of counters, the minimal space that is required for accepting a nonregular language is (log n)ɛ. This is required for weak space bounds on the size of their counters, for real-time and one-way, and for nondeterministic and alternating versions of these automata. The same holds for two-way automata, independent of whether they work with strong or weak space bounds, and of whether they are deterministic, nondeterministic, or alternating. (Here ɛ denotes an arbitrarily small—but fixed—constant; the “space” refers to the values stored in the counters, rather than to the lengths of their binary representation.) On the other hand, we show that the minimal space required for accepting a nonregular language is nɛ for multicounter automata with strong space bounds, both for real-time and one-way versions, independent of whether they are deterministic, nondeterministic, or alternating, and also for real-time and one-way deterministic multicounter automata with weak space bounds. All these bounds are optimal both for unary and general nonregular languages. However, for automata equipped with only one counter, it was known that one-way nondeterministic automata cannot recognize any unary nonregular languages at all, even if the size of the counter is not restricted, while, with weak space bound log n, we present a real-time nondeterministic automaton recognizing a binary nonregular language here.

The chief feature in the psychological literature of Italy since my last report has been the multiplication of periodicals devoted to it. Thus we have received copies of the following new journals:—“The Annali di Freniatria,” of Turin; “Il Manicomio,” of Nocera Inferiore; “Il Pisani,” of Palermo; and “L'Anomalo,” a “Gazzettino,” published at Naples. On the other hand, I regret to say that no copies have been sent since 1888 of Lombroso's always interesting, if sometimes paradoxical, “Archivio di Psichiatria ed Antropologia Criminale.”To some extent these periodicals may be considered as equivalent to our Asylum Reports; and they doubtless show the great activity and zeal with which our specialty is studied in Italy. But from another point of view they seem to me no unmixed advantage. Each periodical is starved by the scattering of so much ability, which was formerly concentrated in fewer journals; and the space left vacant has been, to a great extent; occupied by matters of local, temporary, or secondary interest. When allowance is made for this, Italian psychological literature will be found quite equal to the high level it has attained in former years.

It is now a well established fact that high-level nutrition of the in-lamb ewe during the later stages of pregnancy results in heavy lambs of high vitality at birth and in good milking ewes. On the other hand, when ewes are poorly fed during the same period, or suffer a check, they produce underweight lambs of low vitality and have poor milk yields. While it is agreed that underweight lambs are undesirable, one is often asked whether the larger and sturdier lambs at birth maintain their superiority in later life, a problem on which relatively few results have been published. A study has therefore been made of a large number of birth and weaning weights collected as a normal routine at the Rowett Institute during the past few years.

To the high real-time quality requirement of motion simulation system of airport fire engine simulator, a simulation system with simplified motion model was promoted. The simplified motion model simplifies motion model of vehicle based on application requirement of virtual training of vehicle driving. On one hand, the simplification can reduce calculation amount of simulation, on the other hand, the simplification can make it easier to get parameters of model. Motion simulation system based on simplified motion model of airport fire engine was constructed and experiment was taken. Experiment showed that the motion simulation system has high calculation speed and good fidelity through setting parameters properly.

XML can be as easy to work with as JSON. However, this has not been obvious until now. JSON is easy because it supports only datatypes that are already native to Javascript and uses the same syntax to access them (such as [1:10], ["x"], and “.” notation). XML, on the other hand, supports additional datatypes, and is most commonly handled via SAX or DOM, both of which are low-level and meant to be cross-language. Typical developers want high-level access that feels “native” in the language they are using. These shortcomings have little or nothing to do with XML, and can be remedied by a different API. Software that demonstrates this is presented and described. It uses Python's richer set of abstract datatypes (such as tuples and sets), and provides native Python style syntax with richer semantics than JSON or Javascript.

Simulation Results

Abstract The survey indicates that VANETs use two vital routing protocols namely AODV and AOMDV. AODV is implemented by providing a single dedicated path between source and receiver and it doesn’t search for the alternate path in the case of an emergency situation. On the other hand, AOMDV is implemented by providing an intermediate participant node to reach the receiver i.e., it provides multipath and unlike AODV, it searches for the alternate path in the case of an emergency situation. Due to this capability, AOMDV finds its application in broad areas of research. In this paper, both the protocols are established and their performances are analyzed in terms of PDR, PLR, E2E, and Throughput. The simulation results are obtained using NS2.34. Using these results, the appropriate protocols can be implemented in real-time for various city environments with changeable traffic density and topography in the established network.

In the last decades, Natural Language Processing (NLP) has obtained a high level of success. Interactions between NLP and Serious Games have started and some of them already include NLP techniques. The objectives of this paper are twofold: on the one hand, providing a simple framework to enable analysis of potential uses of NLP in Serious Games and, on the other hand, applying the NLP framework to existing Serious Games and giving an overview of the use of NLP in pedagogical Serious Games. In this paper we present 11 serious games exploiting NLP techniques. We present them systematically, according to the following structure:  first, we highlight possible uses of NLP techniques in Serious Games, second, we describe the type of NLP implemented in the each specific Serious Game and, third, we provide a link to possible purposes of use for the different actors interacting in the Serious Game.

Oocyte meiosis is a prolong series of events that are comprised several intermittent channels in mammals. Oocyte meiosis starts during fetal life and then gets arrested at diplotene stage of first meiotic prophase in follicular oocyte. The continuous transfer of cyclic adenosine 3’, 5’-monophosphate (cAMP) and cyclic guanosine 3’, 5’-monophosphate (cGMP) from encircling granulosa cells to the oocyte through gap junctions helps in the maintenance of their high level required to achieve the long-lasting diplotene arrest so-called germinal vesicle stage. Phosphodiesterase inhibitors have been used to elevate intracellular level of both cyclic nucleotides and prevent spontaneous resumption of meiosis in oocytes under in vitro culture conditions. On the other hand, disruption of gap junction either by pituitary gonadotropin or by physical removal of encircling granulosa cells interrupts transfer of these nucleotides to the oocyte. As a result, intraoocyte cAMP as well as cGMP levels are decreased drastically that initiate downstream pathways to destabilize maturation-promoting factor (MPF). The destabilized MPF initiates meiotic resumption from diplotene arrest in mammalian oocytes. Oocyte meiosis further progresses from metaphase I to metaphase II stage and extrudes first polar body to get converted into haploid female gamete at the time of ovulation. Indeed, high level of cAMP as well as cGMP levels maintains diplotene arrest for a long time in follicular oocytes. On the other hand, transient decrease of their levels drives resumption from diplotene arrest, thereby meiotic maturation process, which enables oocyte to achieve developmental competency. Any defect in this process directly affects oocyte quality and thereby reproductive outcome in mammals including human.

In contrast to many investigations of cellular automata with regard to their ability to accept inputs under certain time constraints, in this paper we are studying cellular automata with regard to their ability to generate strings in real time. Structural properties such as speedup results and closure properties are investigated. On the one hand, constructions for the closure under intersection, reversal and length-preserving homomorphism are presented, whereas on the other hand the nonclosure under union, complementation and arbitrary homomorphism are obtained. Finally, decidability questions such as emptiness, finiteness, equivalence, inclusion, regularity and context-freeness are addressed.
