Backaction-evading measurement of entanglement in optomechanics

2019

We propose here a fully backaction-evading scheme for the measurement of the entanglement between two nanomechanical resonators. The system, which consists of two mechanical oscillators, coupled to a single mode of an electromagnetic resonant cavity through a radiation-pressure interaction term, is driven by two pump tones and four detection tones. As previously discussed in the literature, the former induce entanglement between the two mechanical oscillators, while we show here that a specific choice of phase and amplitude of the detection tones allows for direct pairwise reconstruction of the collective quadrature fluctuations of the mechanical oscillators belonging to quantum-mechanics-f…

Isomer and decay studies for the rp process at IGISOL

2012

This article reviews the decay studies of neutron-deficient nuclei within the mass region \ensuremathA=56--100 performed at the Ion-Guide Isotope Separator On-Line (IGISOL) facility in the University of Jyväskylä over last 25 years. Development from He-jet measurements to on-line mass spectrometry, and eventually to atomic mass measurements and post-trap spectroscopy at IGISOL, has yielded studies of around 100 neutron-deficient nuclei over the years. The studies form a solid foundation to astrophysical rp -process path modelling. The focus is on isomers studied either via spectroscopy or via Penning-trap mass measurements. The review is complemented with recent results on the ground and is…

JYFLTRAP: a Penning trap for precision mass spectroscopy and isobaric purification

2012

In this article a comprehensive description and performance of the double Penning-trap setup JYFLTRAP will be detailed. The setup is designed for atomic mass measurements of both radioactive and stable ions and additionally serves as a very high-resolution mass separator. The setup is coupled to the IGISOL facility at the accelerator laboratory of the University of Jyväskylä. The trap has been online since 2003 and it was shut down in the summer of 2010 for relocation to the upgraded IGISOL facility. Numerous atomic mass and decay energy measurements have been performed using the time-of-flight ion-cyclotron resonance technique. The trap has also been used in several decay spectroscopy expe…

Ligand Ratio Plays a Critical Role in the Design of Optimal Multifunctional Gold Nanoclusters for Targeted Gastric Cancer Therapy

2021

Nanodrug delivery systems (NDDSs) based on water-soluble and atomically precise gold nanoclusters (AuNCs) are under the spotlight due to their great potential in cancer theranostics. Gastric cancer (GC) is one of the most aggressive cancers with a low early diagnosis rate, with drug therapy being the primary means to overcome its increasing incidence. In this work, we designed and characterized a set of 28 targeted nanosystems based on Au144(p-MBA)60 (p-MBA = para-mercaptobenzoic acid) nanocluster to be potentially employed as combination therapy in GC treatment. The proposed multifunctional AuNCs are functionalized with cytotoxic drugs (5-fluorouracil and epirubicin) or inhibitors of diffe…

Stability of moving viscoelastic panels interacting with surrounding fluid

2012

We study a model describing the out-of-plane vibrations of an axially moving viscoelastic panel submerged in flowing fluid. The panel is assumed to travel at a constant velocity between two fixed supports, and it is modeled as a flat panel made of viscoelastic Kelvin-Voigt material. The fluid flow is modeled with the help of the added mass coefficients. The resulting dynamic equation is a partial differential equation of fifth order in space. Five boundary conditions are set for the studied problem. The behavior of the panel is analyzed with the help of its eigenvalues (eigenfrequencies). These characteristics are studied with respect to the velocity of the panel. In our study, we have incl…

Setting Nordic Career Guidance in Context

2020

The introduction to this volume discusses the importance of situating career and career guidance in context. It makes a connection to wider research and writing that challenges the idea that career theory can be global and universal and argues that there is a need for attention to local context and culture. It then moves on to set the scene for a volume focusing on the Nordic countries, by defining the ‘Nordic’ and exploring key features of the region including the Nordic welfare model and the history of collaborations in career guidance across the region. It proposes the four ‘COs’ of Nordic career guidance (context, community, co-construction and collaboration) before outlining the struct…

Ville Vallgrenin museo : museon suunnitteluun vaikuttaneet tekijät ja museolle annetut merkitykset 1920-luvulla

2011

Ville Vallgrenin museo, Porvoon museon erillinen osasto, avattiin toukokuussa 1925. Museossa oli esillä kuvanveistäjä Ville Vallgrenin veistoksia. Tutkimuksen tavoitteena on selvittää eri konteksteja, jotka ovat vaikuttaneet museon suunnitteluun 1920-luvulla, kuvanveisto ja museonäyttelyiden suunnittelu näistä tärkeimpinä. Lisäksi käsitellään museolle annettuja merkityksiä sen perustamisaikana.

Constructing Large 2D Lattices Out of DNA-Tiles.

2021

The predictable nature of deoxyribonucleic acid (DNA) interactions enables assembly of DNA into almost any arbitrary shape with programmable features of nanometer precision. The recent progress of DNA nanotechnology has allowed production of an even wider gamut of possible shapes with high-yield and error-free assembly processes. Most of these structures are, however, limited in size to a nanometer scale. To overcome this limitation, a plethora of studies has been carried out to form larger structures using DNA assemblies as building blocks or tiles. Therefore, DNA tiles have become one of the most widely used building blocks for engineering large, intricate structures with nanometer precis…
