  1. 1. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging

    Författare :Zhongzheng Wang; Ruoli Wang; Elena Gutierrez Farewik; Rodrigo Moreno; Jonas Stålhand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle volume; fascicle length; pennation angle; anisotropy; three-dimensional freehand ultrasound; magnetic resonance imaging; diffusion tensor imaging; magnetic resonance elastography; Muskelvolym; fascikellängd; pennationsvinkel; anisotropi; tredimensionellt frihandsultraljud; magnetisk resonanstomografi; diffusionstensoravbildning; magnetisk resonanselastografi; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. LÄS MER

  2. 2. The roles of demography and natural selection in shaping genome-wide variation of Norway spruce

    Författare :Xi Wang; Pär K. Ingvarsson; Carolina Bernhardsson; Xiao-Ru Wang; Nathaniel Street; Tanja Pyhäjärvi; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; whole-genome resequencing; variant calling; genetic linkage map; nucleotide diversity; natural selection;

    Sammanfattning : Understanding the relative contribution of genetic drift, natural selection, and mutation to genetic variation, and quantifying adaptive evolution and the effects of natural selection in species are enduring goals of evolutionary genetics. Norway spruce (Picea abies) is one of the most important conifer species that dominates from both an ecological and economical point of view in many boreal ecosystems. LÄS MER

  3. 3. Electronic Structure of π-Conjugated Materials and Their Effect on Organic Photovoltaics

    Författare :Chuanfei Wang; Mats Fahlman; Xianjie Liu; Ergang Wang; Zong-Xiang Xu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The great tunability of structure and electronic properties of π-conjugated organic molecules/polymers combined with other advantages such as light weight and flexibility etc., have made organic-based electronics the focus of an exciting still-growing field of physics and chemistry for more than half a century.

  4. 4. Hybridization and Evolution in the Genus Pinus

    Författare :Baosheng Wang; Xiao-Ru Wang; Sally Aitken; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adaptation; biogeography; coalescent simulation; cytoplasmic genome; demographic history; genetic diversity; hybridization; migration; Pinus; population structure; selection; speciation; evolutionär genetik; evolutionary genetics;

    Sammanfattning : Gene flow and hybridization are pervasive in nature, and can lead to different evolutionary outcomes. They can either accelerate divergence and promote speciation or reverse differentiation. The process of divergence and speciation are strongly influenced by both neutral and selective forces.

  5. 5. Fluorescent quantum dots and graphene-based sensors for forensic applications

    Författare :Johnny Jussi; Ying Fu; Simon Dunne; Qin Wang; Ingemar Petermann; Xin Wang; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Quantum Dots; Blood; Forensics; Drugs; Biologisk fysik; Biological Physics;

    Sammanfattning : A key emerging concept within the forensic sciences today areportable measurementdevices, where a much more efficient usage of the resources involved with crime-solving is possible if confirmatory measurements can be realised directly at a crimescene with such devices. Today, the majority of the presently used methods duringcriminal investigation at a crime scene involves measurements of a presumptivenature, which is a vital tool as it enables the screening of samples.
