Thermally drawn multimaterial fibers have experienced rapid development in the past two decades owing to the high scalability, uniformity, and material and structure compatibility of the thermal drawing technique. This article reviews various multimaterial fibers based on different functional structures and their applications in disparate fields. We start from the functional structures achieved in optical fibers developed in the early stage of thermally drawn fibers. Subsequently, we introduce both typical functional structures and unique structures created in multimaterial fibers for varying applications. Next, we present the early attempts in breaking the axial symmetric structures of thermally drawn fibers for extended functionalities. Additionally, we summarize the current progress on creating surface structures on thermally drawn fibers. Finally, we provide an outlook for this trending topic towards wearable devices and smart textiles.

Do So

This chapter and the following both draw the reader into seventeenth-century understandings of the past, and of Boudica in particular, and makes clear that in a time before disciplines, writers of ‘history’ were erudite commentators, immersed in political thought, the classical world, and contemporary ideas, as well as in drama, poetry, and the law. Chapter 1 shows the subtleties of Boudica’s place in history at this early stage by giving sustained attention to the work of Edmund Bolton (1574/5–c.1634), the first person to analyse the written and material evidence for Boudica’s deeds, and the last to do so in depth before the later nineteenth century. Bolton’s distaste for contemporary philosophy and his loyalty to James I were highly influential in determining the way the antiquary approached Boudica and her rebellion; but equally important was Bolton’s deep understanding of historical method and the strictures this placed on his interpretive latitude.

Over the past few decades, we have witnessed tremendous advancements in semiconductor and MEMS technologies, leading to the proliferation of ultra-miniaturized and ultra-low-power (in micro-watt ranges) wearable devices for wellness and healthcare [1]. Most of these wearable sensors are battery powered for their operation. The use of an on-device battery as the primary energy source poses a number of challenges that serve as the key barrier to the development of novel wearable applications and the widespread use of numerous, seamless wearable sensors [5].

AbstractThis paper outlines the main features of the International Schools for Young Astronomers (ISYA), a programme developed by the International Astronomical Union (IAU) in 1967. The main goal of this programme is to support astronomy in developing countries by organizing a school lasting 3 weeks for students with typically a M.Sc. degree. The context in which the ISYA were developed has changed drastically over the past 10 years. We have moved from a time when access to any large telescope was difficult and mainly organized on a national basis, to the situation nowadays where data archives are established at the same time that any major telescope, ground-based or in space, is built, and these archives are accessible from everywhere. The concept of the virtual observatory reinforces this access. However, the rapid development of information and communications technologies and the increasing penetration of internet have not yet removed all barriers to data access. The role of the ISYA is addressed in this context.

Northwestern Chihuahua, Mexico, and the U.S. Southwest share broadly similar pre-colonial cultures and sequences of change. In fact, the present-day international boundary artificially divides a single culture area. Even so, northwestern Chihuahua is not simply a southern extension of the U.S. Southwest. This chapter reviews the past of northwestern Chihuahua from the early pre-ceramic era through late pre-Hispanic times, showing how these cultures were similar to and different from their counterparts in the Southwest. It is clear that maize farming and at least semi-sedentary life were introduced early in Chihuahua, and this formed a basis for the rapid development of subsequent cultures. The apogee of the area’s late pre-colonial period is the famous center of Paquimé (or Casas Grandes). It is widely recognized as one of the most complex societies of the pre-Hispanic Pueblo world.

Abstract For applying shock waves to precise medical procedures like neurosurgery, a reliable generation of micro shock waves is required. Such sensitive applications make limits on usage of conventional underwater shock wave sources like Extracoporeal Shock Waves ESW [1] or micro explosives [2]. In the present study a Q-switched Ho:YAG laser and an optical fiber are used. Advantages of this method over previous shock wave sources are two order of magnitude reduction in focusing area if compared with ESW and elimination of product gases of micro explosives. Nakahara and Nagayama [3] studied underwater shock waves emanated from surface of an optical fiber by pulse Nd:YAG laser input using shadowgraph technique. Their qualitative study limited to visualization of shock waves at its early stage. The present research aims to clarify quantitatively process of the shock wave generation by direct laser beam irradiation through optical fibers, growth and behavior of generated cavities, and structure of heat induced flow in front of the optical fiber.

<p><strong>Abstrak:</strong> Baiknya pondasi sebuah rumah tangga secara tidak langsung berpengaruh terhadap jatuh bangunnya sebuah negara, dan sebaliknya rusaknya pondasi sebuah keluarga berpengaruh terhadap merosot dan berkembangnya sebuah negara. Beberapa tahun belakangan ini jumlah permintaan gugat cerai istri terhadap suami mengalami peningkatan terutama dari isteri yang berkarir. Penelitian ini melihat permasalahan yang dibangun dengan menggunakan pendekatan kualitatif fenomenologis untuk melihat dan memahami faktor perceraian wanita muslimah berkarir di kota Medan berdasarkan fenomena, fakta dan data yang peneliti temui di lapangan. Berdasarkan temuan penelitian didapat bahwa untuk menegakkan konsep ideal sebuah keluarga sangat sulit untuk dilakukan pada masa sekarang. Kondisi perkawinan sekarang sangat berbeda dengan masa dahulu dalam pemaknaan relasi suami isteri. Dahulu pernikahan memiliki posisi sangat sakral, pernikahan dianggap sebagai ibadah, sehingga orang takut untuk bercerai, karena cerai dianggap aib dan dosa.</p><p><strong>Abstract:</strong> <strong>Women Prosecute: A Study of Divorce in Careered-Muslim Women in Medan City</strong>. The good foundation of a household indirectly affects the rise and fall of a country, and vice versa, the damage to a family’s foundation affects the decline and development of a country. In the last decade, the number of divorce petition against husbands has increased, especially from careered-wives. This paper attempts to study the problems using a phenomenological qualitative approach to thoroughly comprehend the factors of divorce of careered-Muslim women in Medan city based on the phenomena, facts and data that researchers encountered in the field. This study finds that to enforce the ideal concept of a family is not an easy task to do at present. The current condition and perception of marital tie within the society is very different from the past. At the early stage of development of human history, marriage were regarded as inherent in religious observance, and thus, people were reluctant to divorce since it was a disgrace and sin.</p><p><strong>Kata Kunci:</strong> gender, feminisme, cerai, wanita karir, Muslimah</p>

The rapid development of online lending in the past decade, while providing convenience and efficiency, also generates large hidden credit risk for the financial system. Will removing financial intermediaries really provide more efficiency to the lending market? This paper used a large dataset with 251,887 loan listings from a pioneer P2P lending platform to investigate the efficiency of the credit-screening mechanism on the P2P lending platform. Our results showed the existence of a TYPE II error in the investors’ decision-making process, which indicated that the investors were predisposed to making inaccurate diagnoses of signals, and gravitated to borrowers with low creditworthiness while inadvertently screening out their counterparts with high creditworthiness. Due to the growing size of the fintech industry, this may pose a systematic risk to the financial system, necessitating regulators’ close attention. Since, investors can better diagnose soft signals, an effective and transparent enlargement of socially related soft information together with a comprehensive and independent credit bureau could mitigate adverse selection in a disintermediation environment.

The current difficult situation with the spread of the COVID 2019 virus forced us to take a new look at the workflow and rebuild medicine as well as the entire education system. The rapid development of computer technologies over the past ten years allows education to find a reasonable way out of a difficult situation. Thus, the existing system of distance education helped to continue students ‘education during the pandemic. The new format of education forced University lecturers (and other educational institutions) to look for the most appropriate and effective ways to implement the educational process. The Physical culture is not an exception. This article suggests and proves the most rational content of conducting remote physical education classes. They improve physical education help to maintain and strengthen the health of the younger generation.
