“It/I” is a two-character theater play in which the human character I (played by a real actor) is taunted and played with by an autonomous computer character It on a computer-controlled, camera-monitored stage. The play, performed before live audiences in November 1997, brought an automatic computer character to a theatrical stage for the first time ever. This paper reports the experience and examines important technical developments needed for the successful production of “It/I”. In particular we describe the interval script paradigm used to program the computer character and the ACTSCRIPT language for communication of actions and goals. Although our experiments have been restricted to physical interactive spaces, we believe that interval scripts and ACTSCRIPT can successfully address the control and management of any virtual environment with a complex temporal structure or a strong underlying narrative.

Abstract A high-speed, high-performance, continuous-flow analyzer is described that operates at two to three times the usual analysis rate without necessitating corrections of the raw data and with no decrease in accuracy or precision. At faster speeds (180-300 samples/h) inductive sample interaction (%Ii), opposite in direction to carry-over, is for the first time quantitatively measured. A correction equation for %Ii was developed, and when it is applied to raw data, the accuracy of the results are significantly improved. Operating characteristics of the high-speed analyzer are described and the desirability of automatic computer corrections is discussed for the high-speed system.

Hardware implementation of discrete adaptive control for a full scale vehicular single degree of freedom (SDOF) active suspension has been discussed in this paper. This paper describes an experimental evaluation of full scale fail-safe adaptive active (SDOF) suspension system that has been performed for the first time. A servo hydraulic force actuator is installed along with passive suspension components to form a fail-safe active suspension. A discrete model reference adaptive control (DMRAC) approach with recursive least square (RLS) estimation and covariance modification has been used for the software/hardware based digital control. A real time computer controlled adaptive active suspension software which shows the experimental response and animation of the results has been developed.

Set Up

We report on an experiment that examined the influence of anthropomorphism and perceived agency on presence, copresence, and social presence in a virtual environment. The experiment varied the level of anthropomorphism of the image of interactants: high anthropomorphism, low anthropomorphism, or no image. Perceived agency was manipulated by telling the participants that the image was either an avatar controlled by a human, or an agent controlled by a computer. The results support the prediction that people respond socially to both human and computer-controlled entities, and that the existence of a virtual image increases tele-presence. Participants interacting with the less-anthropomorphic image reported more copresence and social presence than those interacting with partners represented by either no image at all or by a highly anthropomorphic image of the other, indicating that the more anthropomorphic images set up higher expectations that lead to reduced presence when these expectations were not met.

The article considers the state of scientific and technical developments in the field of improving the efficiency of vibration technology. Production activity in most branches of industrial production is provided by the work of various technological machines and vehicles. The operation of machines, equipment, mechanisms, apparatus and devices in the conditions of the need to ensure high productivity is often accompanied by significant dynamic loads, vibration processes and manifestations of shock interactions of machine elements. Ensuring the reliability and safety of machines requires at all stages of their life cycle serious attention to compliance with certain restrictions on the parameters of the dynamic state of technical objects, the development of methods and means of assessing control and management of dynamic interactions. Modern mechanical engineering is a scientific basis for solving the main problems of machine dynamics, which, in general, is based on scientific potential created by domestic and foreign scientists in the field of theoretical and applied mechanics, theory of mechanisms, dynamics and strength of machines, development of scientific directions in automatic control theory. applied system synthesis, etc. The results of scientific research are reflected in the works of famous scientists. The formed practice of pre-design researches of the created machines, the equipment and the equipment is based on wide use of means of mathematical modeling, application of means of computer engineering. The choice of equipment in production is based on cost, productivity, size, energy consumption, etc. In this regard, there is a question of the need to find and develop new approaches, methods and means to ensure the efficiency and reliability of technological machines and equipment.

The study examines internet newsgroups as a potential mitigating tool in the complex coming-out process of gay male youth. Employing a qualitative discourse analysis of the newsgroup’s messages, the chapter focuses on an Israeli newsgroup that appeals to GLBT (gay, lesbian, bisexual, transgender) youth and operates within the most popular UGC (user-generated content) portal in Israel. The findings indicate that the researched newsgroup functions as a social arena that offers its participants an embracing milieu, where for the first time in their lives they are free of moral judgment of their sexuality. Through four distinct yet interrelated ways, the newsgroup helps its participants to cope with one of the most significant milestones in a gay person’s life – the coming-out process: (1) refuting prevalent stereotypes of homosexuality; (2) facilitating the acceptance of one’s sexual orientation; (3) prompting its disclosure; and (4) creating social relations within and outside the virtual environment.

Abstract Background Diel cycle is of enormous biological importance in that it imposes temporal structure on ecosystem productivity. In the world oceans, microorganisms form complex communities that carry out about half of photosynthesis and the bulk of life-sustaining nutrient cycling. Within these natural microbial assemblages, photoautotrophs, such as Cyanobacteria , display diel rhythmicity in gene expression. To what extent autotrophs and heterotrophs are impacted by light and dark oscillations and how this collectively influences community structure and functionality remains poorly documented. In this study, we compared eight day/night metaproteome profiles of Cyanobacteria and both free-living and attached bacterial fractions from picoplanktonic communities sampled over two consecutive days from the surface north-west Mediterranean Sea. Results Our results showed similar taxonomic structure in both free-living and particle-attached bacteria, dominated by Alphaproteobacteria and Gammaproteobacteria . Temporal rhythmicity in protein expression was observed in both Synechococcales and Rhodobacterales in light-dependent processes such as photosynthesis or UV-stress response. Other biological processes, such as phosphorus or amino acid metabolisms, were also found to cycle in phototrophs. In contrast, proteins from the ubiquitous Pelagibacterales remained stable independently of the day/night oscillations. Conclusion This work integrated for the first time diel comparative metaproteomics on both free-living and particle attached bacterial fractions in coastal oligotrophic environment. Our findings demonstrated a taxa-specific response to diel cycle with a more controlled protein regulation for phototrophs. This study provided additional evidences that timekeeping mechanisms might be widespread among bacteria, broadening our knowledge on diel microbial assemblage dynamics.

The drawbacks of all the existing security techniques have led to a newer technique called 3D Password. The 3D Password authentication technique can accommodate those previous authentication techniques (Textual password, graphical password, biometric password and so on) which make it difficult for hackers to crack because of the inclusion of a 3D virtual environment and its virtual objects. Mapping techniques have evolved over the years with the aid of the computer system, satellite and Global Positioning System (GPS) each location on a map is geo-referenced. This paper proposed a combination of 3D Password security authentication with 3D Interactive Maps for better and more enhanced security, hence allowing the user to select the area he is much familiar with and making it more difficult for hackers to break. Also, a 3D interactive map is an existing technology and a virtual environment, service, commonly used by end-users all around the world. With this, it will make 3D password security authentication more secured and better user-friendly as against developing a specific virtual environment for a user to select a virtual object which he might be seeing for the very first time. This can lead to a user forgetting an object that was chosen in the first place when he is to login at another time interval which could be days, weeks, months or years.

Successful Production

The vitrification of immature germinal vesicle (GV) oocytes is an important way to preserve genetic resources and female fertility. However, it is well known that cryopreserved GV oocytes have very poor developmental ability and that further improvement in this technique is needed. We previously reported the successful vitrification of matured mouse oocytes with enclosed cumulus cells using the calcium-free vitrification solution supplemented with ethylene glycol (EG) by the minimal volume cooling (MVC) method. In this study, we investigated whether our method is applicable to the vitrification of mouse oocytes at the GV stage (GV oocytes). Following maturation and fertilization in vitro, vitrified GV oocytes showed high survival (94.3 ± 2.0%) and maturation (94.3 ± 2.1%) rates. Although the fertilization and blastocyst rates of vitrified oocytes (fertilization: 46.6 ± 4.9% and blastocyst: 46.6 ± 3.0%) were significantly lower than those of fresh oocytes (fertilization: 73.0 ± 7.1% and blastocyst: 71.6 ± 8.0%) (P < 0.01), there were no differences in the ability to develop to term between fresh oocytes (50.0 ± 8.4%) and vitrified oocytes (37.5 ± 4.6%) (P > 0.05). In conclusion, we here show, for the first time, the efficient production of live mice derived from vitrified GV oocytes.
