Low-Noise Amplification and Frequency Conversion with a Multiport Microwave Optomechanical Device
2016
High-gain amplifiers of electromagnetic signals operating near the quantum limit are crucial for quantum information systems and ultrasensitive quantum measurements. However, the existing techniques have a limited gain-bandwidth product and only operate with weak input signals. Here we demonstrate a two-port optomechanical scheme for amplification and routing of microwave signals, a system that simultaneously performs high-gain amplification and frequency conversion in the quantum regime. Our amplifier, implemented in a two-cavity microwave optomechanical device, shows 41 dB of gain and has a high dynamic range, handling input signals up to $10^{13}$ photons per second, three orders of magn…
Novel high-performance QCA Fredkin gate and designing scalable QCA binary to gray and vice versa
2022
AbstractIn the design of digital logic circuits, QCA technology is an excellent alternative to CMOS technology. Its advantages over CMOS include low power consumption, fast circuit switching, and nanoscale design. Circuits that convert data between different formats are code converters. Code converters have an essential role in high-performance computing and signal processing. In this paper, first, we proposed a novel QCA structure for the quantum reversible Fredkin gate. Second, we proposed 4-bit and 8-bit QCA binary-to-gray converter and vice versa. For the second proposal, both reversible and irreversible structures are suggested. The proposed structures are scalable up to N bits. To cha…
Quality of Life of Neet Youth across Europe: The Perceived Welfare of the 'out-of-School Jobless'
2019
International audience; Youth who are 'not in employment, education or training' NEET have become a prominent population sub-group in European social policy discussions. Recent research has begun exploring the conceptual clarity of this social group (Furlong, 2006), predictors and outcomes of NEET membership (Bruno, Marelli, and Signorelli, 2014), and cross-national variations in group composition and characteristics (B?lan, 2015). Indeed, an emerging body of evidence points to the strong role played by institutional arrangements, such as national education systems and labour market policies, in predicting youth unemployment and joblessness (Breen and Buchmann, 2002). However, international…
Magnomechanics in suspended magnetic beams
2021
Cavity optomechanical systems have become a popular playground for studies of controllable nonlinear interactions between light and motion. Owing to the large speed of light, realizing cavity optomechanics in the microwave frequency range requires cavities up to several mm in size, hence making it hard to embed several of them on the same chip. An alternative scheme with much smaller footprint is provided by magnomechanics, where the electromagnetic cavity is replaced by a magnet undergoing ferromagnetic resonance, and the optomechanical coupling originates from magnetic shape anisotropy. Here, we consider the magnomechanical interaction occurring in a suspended magnetic beam -- a scheme in…
Low-Rank Tucker-2 Model for Multi-Subject fMRI Data Decomposition with Spatial Sparsity Constraint
2022
Tucker decomposition can provide an intuitive summary to understand brain function by decomposing multi-subject fMRI data into a core tensor and multiple factor matrices, and was mostly used to extract functional connectivity patterns across time/subjects using orthogonality constraints. However, these algorithms are unsuitable for extracting common spatial and temporal patterns across subjects due to distinct characteristics such as high-level noise. Motivated by a successful application of Tucker decomposition to image denoising and the intrinsic sparsity of spatial activations in fMRI, we propose a low-rank Tucker-2 model with spatial sparsity constraint to analyze multi-subject fMRI dat…
Iän, sukupuolen ja harjoittelun yhteys reaktionopeuteen mies- ja naisveteraaniurheilijoilla
2013
IÄN, SUKUPUOLEN JA HARJOITTELUN YHTEYS REAKTIONOPEUTEEN MIES - JA NAISVETERAANIURHEILIJOILLA Laura Vainio Pro gradu –tutkielma Gerontologia ja kansanterveys Jyväskylän yliopisto, liikuntatieteellinen tiedekunta, terveystieteiden laitos Kevät 2013 43 sivua, 1 liite Yksi ikääntymisen mukana tapahtuva toimintojen heikkeneminen ilmenee ärsykkeisiin reagoimisen ja reaktionopeuden hidastumisena. Mitä enemmän ikääntyvillä ihmisillä on nopeutta, kestävyyttä ja lihasvoimaa, sitä paremmin he suoriutuvat jokapäiväisistä arkiaskareista. Fyysinen aktiivisuus on tärkeä osa ikääntyvän ihmisen elämässä. Harjoittelun on todettu vaikuttavan reaktionopeuteen parantavasti. Tutkimuksen tarkoituksena oli tutkia …
Filtration of Nordic recirculating aquaculture system wastewater : Effects on microalgal growth, nutrient removal, and nutritional value
2021
Microalgal bioremediation of recirculating aquaculture system (RAS) wastewater represents an alternative for wastewater treatment with the potential to generate valuable biomass. This study evaluated the effects of removing biological contamination and suspended solids from Nordic area RAS wastewater through filtration with 0.45 μm filters on the performance and nutritional value of microalgae. All three tested green microalgae (Haematococcus pluvialis, Monoraphidium griffithii, and Selenastrum sp.) were able to grow in raw (unfiltered) and filtered RAS wastewater. Cultivation in raw RAS wastewater decreased the ω-3 and ω-6 fatty acid content of H. pluvialis as compared to filtered wastewat…
Assessment of Classifiers and Remote Sensing Features of Hyperspectral Imagery and Stereo-Photogrammetric Point Clouds for Recognition of Tree Specie…
2018
Recognition of tree species and geospatial information on tree species composition is essential for forest management. In this study, tree species recognition was examined using hyperspectral imagery from visible to near-infrared (VNIR) and short-wave infrared (SWIR) camera sensors in combination with a 3D photogrammetric canopy surface model based on RGB camera stereo-imagery. An arboretum with a diverse selection of 26 tree species from 14 genera was used as a test area. Aerial hyperspectral imagery and high spatial resolution photogrammetric color imagery were acquired from the test area using unmanned aerial vehicle (UAV) borne sensors. Hyperspectral imagery was processed to calibrated …
Dependence between renewable energy related critical metal futures and producer equity markets across varying market conditions
2022
We study the dependence of renewable energy production-related critical metal futures and producer equity returns, compared to the non-renewable energy (oil and natural gas) and some other globally relevant commodity markets. We find different asymmetric and symmetric dependencies in these commodity markets. The dependence is asymmetric in the most important critical metal markets, i.e., of silver, copper, and platinum. Still, surprisingly, for example, in the oil market, the relationship is symmetric, and no relationship is found in the natural gas market. Furthermore, the oil and agricultural markets have homogenous dependence structures in most market conditions, so the information trans…
Les rapports des jeunes au travail
2018
Rapport d'étape; Ce rapport d'étape souligne combien le rapport des jeunes à la vie professionnelle ne peut se décliner au singulier et englobe une multiplicité d'informations subjectives, négatives et positives qui s'entrecroisent. Au fil des entretiens, les jeunes confirment la place importante du travail dans leur vie et souhaitent s'investir dans un travail qui leur procure du « plaisir » et revêt de la valeur à leurs propres yeux.
