Spectroscopic studies of semiconducting single-walled carbon nanotubes
2010
The unique nature of optical properties of single-walled carbon nanotubes (SWCNT), together with their promising potential applications, have created enormous interest towards the photophysics of SWCNT. Many aspects of carbon nanotubes originate from the electronic structure of carbon honeycomb lattice and one-dimensionality. SWCNTs exist in various chiral structures and diameters, which the optical and electrical properties are dependent on. It has been discovered that SWCNT excited states are excitonic with strong Coulomb interaction between the electron and the hole. However, many features of excitons are not yet well defined, such as absorption cross-sections, fluorescence quantum yield…
Research literature clustering using diffusion maps
2013
We apply the knowledge discovery process to the mapping of current topics in a particular field of science. We are interested in how articles form clusters and what are the contents of the found clusters. A framework involving web scraping, keyword extraction, dimensionality reduction and clustering using the diffusion map algorithm is presented. We use publicly available information about articles in high-impact journals. The method should be of use to practitioners or scientists who want to overview recent research in a field of science. As a case study, we map the topics in data mining literature in the year 2011. peerReviewed
Vaihdemarkkinoiden uudet kasvunlähteet
2014
Tutkimuksessa etsittiin uusia kasvunlähteitä vaihteistojen valmistukseen, uusille energia-aloille ja teollisuusvaihde puolelle. Alojen kaupallinen kiinnostavuus tutkittiin Moventaksen kannalta sekä alustavasti vaihteiden tarve kyseisillä aloilla. Lisäksi tutkittiin mahdollisia tulevaisuuden kasvunaloja vaihdemarkkinoilla. Tavoitteena oli löytää aloja, joilla valmistetaan Jyväskylän tuotantotehtaiden kaltaisia vaihteistoja ja mahdollisesti saada tulevaisuudessa tuotantoon myös sellaisilta aloilta mihin ei ole ennen panostettu. Alkuun aloin tutkimaan aloja yleisellä tasolla ja kyseisistä aloista tehtiin taulukkoon analysointi. Analysoinnin pohjalta valittiin kaksi alaa paremmin selvitettävien…
Infection-induced chromatin modifications facilitate translocation of herpes simplex virus capsids to the inner nuclear membrane
2021
Herpes simplex virus capsids are assembled and packaged in the nucleus and move by diffusion through the nucleoplasm to the nuclear envelope for egress. Analyzing their motion provides conclusions not only on capsid transport but also on the properties of the nuclear environment during infection. We utilized live-cell imaging and single-particle tracking to characterize capsid motion relative to the host chromatin. The data indicate that as the chromatin was marginalized toward the nuclear envelope it presented a restrictive barrier to the capsids. However, later in infection this barrier became more permissive and the probability of capsids to enter the chromatin increased. Thus, although …
