The paper gives analysis of feasibility of using linguistic steganographic trigger-containers as means of linguistic-based text watermarking. The proposed approah is based on the previous experimental research in the context of Russian native speaker text juncture perception. It was posited that specific minimal text modifications addressed in the paper may be used as means of text watermarking with the aim of tracking the leak of information for the purposes of taking legal actions, enforcing non-disclosure agreements, and testing for internal vulnerabilities. There is analyzed the viability of altering paragraph juncture points in Russian texts and, through the use of the corresponding trigger-containers, usage of this alteration as a means of linguistic watermarking.

This study reports on an experimental research carried out with 50 Spanish-L1 trainees, divided into 2 groups: A & B. Both groups were presented with a traditional-teacher centered approach based on controlled exercises (repetition, imitation), but group B added a communicative component in which students completed a battery of sequenced tasks with a focus on phonological form. Both groups recorded a speaking test before & after instruction which was used to measure and compare degrees of accentedness, frequency & duration of pauses and nuclear stress placement. Ten English-native-speaker-raters judged the recordings to determine the speakers’ degree of perceived accentedness. Two specialists, using inter-marker reliability, segmented the transcriptions of recordings and identified nuclear stress placement. Another two specialists identified empty pauses. Multivariate analysis was used to measure results. Overall, group B (learners exposed to the communicative component) obtained better results in all 3 parameters than the other group. Finally, some pedagogical implications for the teaching of L2 pronunciation in ELT contexts will be discussed.

Learning English

Listening is one of the most important skill in learning language for young learners, because the first way to learn language start from learning how to listen. In learning English, most of young learners in Indonesia found some difficulties to listen directly from the native speaker or from the environment, such as from young learners’ school or from young learners’ family, it happened because English is still as the second language in Indonesia which is not use in daily life. Many media uses by most of schools in Indonesia to improve young leraners’ competencies in English, for example by using some application from smartphone or by using song. Here, the researchers choose nursery rhymes song as an alternative media in improving young learners’ listening skill. The experimental research design was employed. The experimental group was taught using nursery rhymes song while the control group was taught using the conventional method. There are two classes  in the same level at six grade level from SDUT BUMI KARTINI JEPARA participated in this study, they are from maroco and mesir class. The findings indicated that nursery rhymes song significantly improved the students’ listening skill toward learning English. This study concluded that nursery rhymes song is one of media that is very effective for improving young learners’ listening skill because young learners are very happy to learn English while singing the nursery rhymes song.

The cobalt disilicide/silicon system has potential applications as a metal-base and as a permeable-base transistor. Although thin, low defect density, films of CoSi2 on Si(111) have been successfully grown, there are reasons to believe that Si(100)/CoSi2 may be better suited to the transmission of electrons at the silicon/silicide interface than Si(111)/CoSi2. A TEM study of the formation of CoSi2 on Si(100) is therefore being conducted. We have previously reported TEM observations on Si(111)/CoSi2 grown both in situ, in an ultra high vacuum (UHV) TEM and ex situ, in a conventional Molecular Beam Epitaxy system.The procedures used for the MBE growth have been described elsewhere. In situ experiments were performed in a JEOL 200CX electron microscope, extensively modified to give a vacuum of better than 10-9 T in the specimen region and the capacity to do in situ sample heating and deposition. Cobalt was deposited onto clean Si(100) samples by thermal evaporation from cobalt-coated Ta filaments.

Ultraviolet laser-irradiation can be used to induce an insulator-to-conductor phase transition on the surface of Kapton polyimide. Such structures have potential applications as resistors or conductors for VLSI applications as well as general utility electrodes. Although the percolative nature of the phase transformation has been well-established, there has been little definitive work on the mechanism or extent of transformation. In particular, there has been considerable debate about whether or not the transition is primarily photothermal in nature, as we propose, or photochemical. In this study, cross-sectional optical microscopy and transmission electron microscopy are utilized to characterize the nature of microstructural changes associated with the laser-induced pyrolysis of polyimide.Laser-modified polyimide samples initially 12 μm thick were prepared in cross-section by standard ultramicrotomy. Resulting contraction in parallel to the film surface has led to distortions in apparent magnification. The scale bars shown are calibrated for the direction normal to the film surface only.

The fabrication of multilayer films (MLF) with layer thicknesses down to one monolayer has led to the development of materials with unique properties not found in bulk materials. The properties of interest depend critically on the structure and composition of the films, with the interfacial regions between the layers being of particular importance. There are a number of magnetic MLF systems based on Co, several of which have potential applications as perpendicular magnetic (e.g Co/Cr) or magneto-optic (e.g. Co/Pt) recording media. Of particular concern are the effects of parameters such as crystallographic texture and interface roughness, which are determined by the fabrication conditions, on magnetic properties and structure.In this study we have fabricated Co-based MLF by UHV thermal evaporation in the prechamber of an atom probe field-ion microscope (AP). The multilayers were deposited simultaneously onto cobalt field-ion specimens (for AP and position-sensitive atom probe (POSAP) microanalysis without exposure to atmosphere) and onto the flat (001) surface of oxidised silicon wafers (for subsequent study in cross-section using high-resolution electron microscopy (HREM) in a JEOL 4000EX. Deposi-tion was from W filaments loaded with material in the form of wire (Co, Fe, Ni, Pt and Au) or flakes (Cr). The base pressure in the chamber was around 8×10−8 torr during deposition with a typical deposition rate of 0.05 - 0.2nm/s.

Synthetic Microbial Communities

Microbial communities drive diverse processes that impact nearly everything on this planet, from global biogeochemical cycles to human health. Harnessing the power of these microorganisms could provide solutions to many of the challenges that face society. However, naturally occurring microbial communities are not optimized for anthropogenic use. An emerging area of research is focusing on engineering synthetic microbial communities to carry out predefined functions. Microbial community engineers are applying design principles like top-down and bottom-up approaches to create synthetic microbial communities having a myriad of real-life applications in health care, disease prevention, and environmental remediation. Multiple genetic engineering tools and delivery approaches can be used to ‘knock-in' new gene functions into microbial communities. A systematic study of the microbial interactions, community assembling principles, and engineering tools are necessary for us to understand the microbial community and to better utilize them. Continued analysis and effort are required to further the current and potential applications of synthetic microbial communities.
