Question: Which of the companies involved with the three-dimensional integrated circuit was founded first? Passage:In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3D IC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.

Question: How much time was between the periods? Passage:Prior to Nepal’s unification, Srēṣṭha was a collective high-status title given to those Hindu clans referred to as 'Bhāju' (from Sanskrit bhadralok) who served as the key non-Brahmin class of ruling, administrative and merchant class of the Malla courts. From within this broad Srēṣṭha groups are two distinct caste groups. First, they count among them the high-caste aristocratic Kshatriyas, locally pronounced as Chatharīya, who are descended from the nobles and courtiers of the Malla period and consist of the ruling, land-owning and literate Hindu caste group of the Nepal Mandala, which later formed the core of government bureaucracy during the Shah and Rana period. Second, Srēṣṭha title is also attributed to the Pāñchthariya, who now mostly write their surnames as 'Shrestha', who were historically the Hindu merchant clans of the Valley, as opposed to the Buddhist merchant caste of Urāy. These Pāñchthariyas have Vaishya status in the traditional varna framework. Srēṣṭha group has also incorporated in it the socially upward Jyapu farmers and other peasants especially outside the Valley as a means of the Sanskritisation process, although their status is not accepted by the upper-level Srēṣṭha castes.

Question: Does the town where Mootz was a boy's choir member have more people living in it than the town where he was born? Passage:Born August 18, 1976 in Wetzlar, Germany, Mootz served an apprenticeship in classical music and was a member of the boy's choir of Windsbach. After studying music engineering at the SAE Institute, Mootz worked with the experimental hip hop/illbient label Chrome, an offshoot of Force Inc Music Works. Over the course of several drum and bass albums and many singles, and as A&R manager for Chrome, later renamed Position Chrome, Panacea became known for pushing the bounds of the drum and bass genre into industrial and hardcore territory, and for energetic DJ sets which fused these genres in a live setting. With his side project m, he explored a more minimal side of electronic music, first in the realm of clicks 'n' cuts, and later in the dark ambient territory pioneered by the likes of Lustmord. Mootz lives and produces in Sommerhausen, a countryside town near Würzburg.
