Dynamic transition of current-driven single-skyrmion motion in a room-temperature chiral-lattice magnet

Driving and controlling single-skyrmion motion promises skyrmion-based spintronic applications. Recently progress has been made in moving skyrmionic bubbles in thin-film heterostructures and low-temperature chiral skyrmions in the FeGe helimagnet by electric current. Here, we report the motion tracking and control of a single skyrmion at room temperature in the chiral-lattice magnet Co9Zn9Mn2 using nanosecond current pulses. We have directly observed that the skyrmion Hall motion reverses its direction upon the reversal of skyrmion topological number using Lorentz transmission electron microscopy. Systematic measurements of the single-skyrmion trace as a function of electric current reveal a dynamic transition from the static pinned state to the linear flow motion via a creep event, in agreement with the theoretical prediction. We have clarified the role of skyrmion pinning and evaluated the intrinsic skyrmion Hall angle and the skyrmion velocity in the course of the dynamic transition. Our results pave a way to skyrmion applications in spintronic devices.

Transformasi Rumah Panggung Masyarakat Loloan Timur dalam Pemajuan Kebudayaan

Traditional technology is one of cultural advancement objects that can be found in Loloan stilt houses which are undergoing transformation and decline in quantity. This paper aims to know shape and determinants of stilt houses transformation in East Loloan, as well as to reveal the implications in terms of cultural advancement program. The study applied qualitative methods which were analyzed interpretive descriptive. The results showed that the stilt house consist two forms and has three levels based on the cosmological community. Transformation of houses on stilts, namely addition of space and changes in function of underside caused by determinants: social change, cultural dynamic, transition livelihoods, technology development, activity change, family members structure, build condition, land area, and interest of homeowner. The implication is that most of the aspects of the cultural advancement program have been fulfilled, except for the coaching aspect which has not been touched by community or government.

The Dynamic Transition of Persistence toward the Viable but Nonculturable State during Stationary Phase Is Driven by Protein Aggregation

While persistence and the viable but nonculturable (VBNC) state are currently investigated in isolation, our results strongly indicate that these phenotypes represent different stages of the same dormancy program and that they should therefore be studied within the same conceptual framework. Moreover, we show here for the first time that the dynamics of protein aggregation perfectly match the onset and further development of bacterial dormancy and that different dormant phenotypes are linked to different stages of protein aggregation.

Being young female Muslims in Islamic fictions: Moral anxiety, faith primacy and ideal image discourse

This article examines the representation of Indonesian young female Muslims in Asma Nadia’s works. While previous studies have drawn dynamic transition in real life, this study provides an alternative narrative of being a young female Muslim in Islamic fiction in the context of simultaneous contemporary development in Indonesia with the raising of public piety. This study employed textual analysis method by making categories based on specific themes and understanding each conversation, storyline, and setting of Nadia’s three works, namely “Assalamualaikum Beijing” (“May Peace Be With You, Beijing”), “Jilbab Traveller: Love Sparks in Korea,” and “OTW Nikah” (“On The Way to Marriage”). The author concludes that Asma Nadia places moral anxiety and faith primacy as a frame young female Muslims experience. Moral anxiety reflects a dilemma of the proper way and advantageous outcome to achieve a successful transition. Faith primacy describes a set of spirits for connecting Islamic values and virtuous roles in each life stage. Furthermore, like many popular cultures containing the ideology of contestation, Asma Nadia’s works also provide a discourse about an ideal image that potentially influences and forms the imagination of readers.
