Hidden attractors and multistability in a modified Chua’s circuit

2021

The first hidden chaotic attractor was discovered in a dimensionless piecewise-linear Chua’s system with a special Chua’s diode. But designing such physical Chua’s circuit is a challenging task due to the distinct slopes of Chua’s diode. In this paper, a modified Chua’s circuit is implemented using a 5-segment piecewise-linear Chua’s diode. In particular, the coexisting phenomena of hidden attractors and three point attractors are noticed in the entire period-doubling bifurcation route. Attraction basins of different coexisting attractors are explored. It is demonstrated that the hidden attractors have very small basins of attraction not being connected with any fixed point. The PSIM circui…

Remote but Connected : Lapland as a Scene of Transnational Crime in Ivalo

2021

Set in a small town in the north of Finland, the crime TV series Ivalo (Arctic Circle, Finland, 2018) exemplifies the fascination of Nordic Noir with ‘remote’ locations as scenes of transnational crime. The plot seems to forebode the corona pandemic, portraying the spread of a life-threatening ‘Yemenite virus’ developed as a biological weapon from the Balkans to Lapland. In this article, I analyze how the virus narrative allows the series to bring new perspectives on Nordic Noir. The narrative emphasizes international connections while creating representations of places that can be characterized as both translocal (Greiner and Sakdapolrak 2013) and glocal (Robertson 2012). Because of its fa…

Microbeam SEE Analysis of MIM Capacitors for GaN Amplifiers

2018

Broad-beam and microbeam single-event effect tests were performed on metal–insulator–metal capacitors with three different thicknesses of silicon nitride (Si3N4) dielectric insulator: 250, 500, and 750 nm. The broad-beam tests indicated that the devices with the thicker, 500- and 750-nm dielectric did not have a greater breakdown voltage. The surrounding structures of the capacitor were suspected to be a possible cause. Microbeam techniques made it possible to localize the failure location for the 500- and 750-nm devices. The failure occurs in the air bridge structure connected to the top capacitor plate, which can therefore be considered as an edge effect, while for the 250-nm devices, the…

Higgs-Inflaton Mixing and Vacuum Stability

2019

The quartic and trilinear Higgs field couplings to an additional real scalar are renormalizable, gauge and Lorentz invariant. Thus, on general grounds, one expects such couplings between the Higgs and an inflaton in quantum field theory. In particular, the (often omitted) trilinear coupling is motivated by the need for reheating the Universe after inflation, whereby the inflaton decays into the Standard Model (SM) particles. Such a coupling necessarily leads to the Higgs-inflaton mixing, which could stabilize the electroweak vacuum by increasing the Higgs self-coupling. We find that the inflationary constraints on the trilinear coupling are weak such that the Higgs-inflaton mixing up to ord…

Suomalainen korkeakoulutus kriisissä?

2005

”Voi liioittelematta sanoa, että kaikki suomalaiset yliopistot kuuluvat ’maailmanluokan’ yliopistoihin. Mistä siis nousee Jorma Rantasen ja Anne Brunilan raporteissa esitetty ehdotus luoda Suomeen muutama ’maailmanluokan’ yliopisto, joiden ohella olisi kansallisen tai maakunnallisen tason opinahjoja? Kysymys näyttäisi olevan koulutuspolitiikan suunnan muutosyrityksistä kohti markkinatalouden kilpailuun perustuvaa arvomaailmaa”, kirjoittaa professori Jussi Välimaa.

Kotoutumiskoulutuksen opetussuunnitelman perusteet kuvaa tavoitettaan osallisuutta epämääräisesti ja kapeasti

2023

Kotoutumiskoulutuksen uudessa perusteasiakirjassa korostuu osallisuuden käsite. Se jää kuitenkin määrittelemättä: osallisuuteen viitataan sekä kapearajaisesti työmarkkinaosallisuutena että epäsuorasti niin, että käsitteen varsinainen merkitys jää avoimeksi. Tutkimuskirjallisuudessa osallisuus edellyttää laaja-alaista sosiaalis-yhteiskunnallista kuulumista ja yhdenvertaisuutta. nonPeerReviewed

Projekteilla parempaa laatua yliopistoihin?

2005

Markkinatalousvetoisen kulttuurin soveltaminen yliopistoihin ei ole ongelmatonta. Erilaiset laadun kohottamisen nimissä tehtävät kehittämishankkeet ilmentävät markkinataloustumista keskusjohtoisina ja nopeatempoisina. Onnistuessaan kehittämishanke luo perustan aidoille uudistuksille.

A field experiment for understanding the unintended impact of Internet monitoring on employees : Policy satisfaction, organizational citizenship beha…

2019

Internet monitoring is widely deployed in organizations as an attempt to regulate employees’ cyberloafing behaviour, which is defined as employees’ usage of Internet for non-work-related purposes. Although previous studies have examined the effectiveness of Internet monitoring in regulating employees’ cyberloafing, the impact of Internet monitoring on employees’ perceptions or behaviours other than cyberloafing has not been investigated. As a first step to address this research gap, we conduct a field experiment to study the impact of Internet monitoring on employees’ policy satisfaction, organizational citizenship behaviour (OCB) and work motivation. We found that Internet monitoring decre…

Life-Space Mobility in Parkinson's Disease: Associations with Motor and Non-Motor Symptoms.

2019

Background To describe life-space mobility and explore associations of motor and non-motor symptoms with life-space mobility in people with Parkinson’s disease (PD). Methods About 164 community-dwelling persons with PD (mean age 71.6 years, 64.6% men) received a postal survey and a subsequent home visit. Motor assessments included perceived walking difficulties (Walk-12G), mobility (Timed Up and Go test), motor symptoms (UPDRS-III), and freezing of gait (item 3, FOG-Qsa). Non-motor symptoms included depressive symptoms (GDS-15), pain, fatigue (NHP-EN), and global cognition (MoCA). Life-space mobility was assessed with the life-space assessment (LSA). Calculations included composite score (r…
