1. 21. Exploring the multiscale 3D architecture of human chromosome contact networks

   Författare :Dolores Bernenko; Ludvig Lizana; Martin Rosvall; Petter Holme; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; community detection; DNA 3D organization; Hi-C; network science; DNA-DNA contact data;

   Sammanfattning : Cells regulate genes to coordinate essential functions allowing cells to grow, divide, specialize, and respond to stresses. While regulatory proteins are the most common way to control these genes, the DNA’s 3D structure also plays a critical role as it affects how proteins access genes and how regulatory DNA elements interact over large genomic distances.

3. 22. Applications of Si1-xGex alloys for Ge devices and monolithic 3D integration

   Författare :Konstantinos Garidis; Per-Erik Hellström; Mikael Östling; Sten Vollebregt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Silicon; germanium; epitaxy; selective; pn junction; germanium on insulator; GOI; Ge PFET; bonding; monolithic; sequential; three dimensional; 3D; low temperature; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : As the semiconductor industry moves beyond the 10 nm node, power consumption constraints and reduction of the negative impact of parasitic elements become important. Silicon germanium (Si1−xGex) alloys have been used to amplify the performance of Si based devices and integrated circuits (ICs) for decades. LÄS MER

   Sammanfattning : Monolithic three-dimensional (M3D) integration, it has been proposed,can overcome the limitations of further circuits’ performance improvementand functionality expansion. The emergence of the internet of things (IoT) isdriving the semiconductor industry toward the fabrication of higher-performancecircuits with diverse functionality. LÄS MER

5. 24. Additive Manufacturing and Integration of 3D MEMS using Ultrafast Lasers and Magnetic Assembly

   Författare :Simone Pagliano; Frank Niklaus; Göran Stemme; Gijs Krijnen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; 3D printing; 3D micromachining; two-photon polymerization; MEMS; polyimide; ultrafast laser; laser micromachining; vertical integration; magnetic assembly; stochastic assembly; diminutive chips;

   Sammanfattning : The geometry of MEMS devices is limited by the technologies used to fabricate them. Today, microsystems are manufactured with patterning technologies that allow only for 2D and 2.5D geometries. LÄS MER

7. 25. Illumination matters. Revisiting the Roman house in a new light

   Författare :Danilo Marco Campanaro; Digital Arkeologi Laboratoriet DARK Lab; []
   Nyckelord :HUMANIORA; HUMANITIES; House of the Greek Epigrams; Roman domestic space; Pompeii; lighting simulation; lamps; digital archaeology; 3D; virtual reality; eye-tracking; 3D GIS;

   Sammanfattning : Interpreting the social complexity of the Roman house requires a careful evaluation of existing evidence. With this in mind, recent work in the field has proposed a variety of different approaches, focusing each time on a specific type of source (architecture and décor, ancient texts, material evidence from excavated houses), each in turn recursively deemed more adequate for the purpose or more fruitful and less biased.
