Real-Time Temporal Superpixels for Unsupervised Remote Photoplethysmography

2018

International audience; Segmentation is a critical step for many computer vision applications. Among them, the remote photoplethys-mography technique is significantly impacted by the quality of region of interest segmentation. With the heart-rate estimation accuracy, the processing time is obviously a key issue for real-time monitoring. Recent face detection algorithms can perform real-time processing, however for unsupervised algorithms, i.e. without any subject detection based on supervised learning, existing methods are not able to achieve real-time on regular platform. In this paper, we propose a new method to perform real-time un-supervised remote photoplethysmograhy based on efficient…

Phase dynamics in graphene-based Josephson junctions in the presence of thermal and correlated fluctuations

2014

In this work we study by numerical methods the phase dynamics in ballistic graphene-based short Josephson junctions. The supercurrent through a graphene junction shows a non-sinusoidal phase-dependence, unlike a conventional junction ruled by the well-known d.c. Josephson relation. A superconductor-graphene-superconductor system exhibits superconductive quantum metastable states similar to those present in normal current-biased JJs. We explore the effects of thermal and correlated fluctuations on the escape time from these metastable states, when the system is stimulated by an oscillating bias current. As a first step, the analysis is carried out in the presence of an external Gaussian whit…

Plasma cell-free DNA in diagnostic KRAS mutation testing

2015

Epidermaalisen kasvutekijän reseptorin (EGFR) monoklonaalisia vasta-aineita (mAb) käytetään apuna metastaattisen kolorektaalisyövän (mCRC) hoidossa. Aktivoivat mutaatiot KRAS- ja NRAS-onkogeeneissä tekevät syöpäsolut vastustuskykyisiksi anti-EGFR-vasta-aineille, ja tästä syystä tuumorit tulee genotyypittää ennen hoidon aloittamista. Kudosbiopsian ottaminen on kuitenkin invasiivinen toimenpide, eikä näyte välttämättä edusta kattavasti syövän kaikkien solupopulaatioiden geneettisiä muutoksia. Verenkierron solunulkoisen DNA:n (cfDNA) on havaittu sisältävän maligneista soluista lähtöisin olevia onkogeenisiä mutaatioita, ja se voi olla hyvä vaihtoehtoinen tuumoriperäisen DNA:n lähde. Kehitimme j…

In vitro and in vivo characterization of porcine acellular dermal matrix for gingival augmentation procedures

2013

Recently, porcine acellular dermal matrix (PADM) has been proposed as a possible alternative to autogenous grafts in periodontal plastic surgery. The aim of the present study was to investigate the in vitro responses of four different oral cell lines cultured on a novel PADM. Furthermore, tissue reaction to PADM was evaluated histologically after subcutaneous implantation in mice.Human gingival fibroblasts (HGF), human osteoblast-like cells, human umbilical vein endothelial cells and human oral keratinocytes (HOK) were cultured and transferred on to the PADM. A tissue culture polystyrene surface served as the control. The viability of all tested cell lines on PADM was measured by using the …

INVOLUTIONS ON KNOT GROUPS AND VARIETIES OF REPRESENTATIONS IN A LIE GROUP

2002

We prove the existence of a rationalisation [Formula: see text] of a classical or high-dimensional knot group Π which admits an involution if the Alexander polynomials of the knot are reciprocal. Using the group [Formula: see text] and its involution, we study the local structure, in the neighbourhood of an abelian representation, of the space of representation of the knot group Π in a a Lie group. We apply these results to the groups of classical prime knots up to 10 crossings.

Kolorektālā vēža skrīninga atsaucību veicinošie faktori ģimenes ārsta praksē

2020

Aktualitāte.Kolorektālais vēzis (KRV) jeb zarnu vēzis ir plaši sastopams ne tikai Latvijā, bet gan visā pasaulē. Globāli tas ir otrs biežāk diagnosticētais vēzis un mirstības ziņā KRV ierindojas 3.vietā. 2018. gadā visā pasaulē tika diagnosticēti 1,8 miljoni kolorektālā vēža gadījumu, un 861,000 pacientu miruši vēža dēļ, balstoties uz Pasaules Veselības Organizācijas GLOBOCAN datiem. 2019.gadā tikai 15% no Latvijas mērķa grupas iedzīvotājiem veikuši KRV skrīningu. Darba mērķis ir noskaidrot motivējošos faktorus, kuri veicinājuši iedzīvotājus piedalīties valsts organizētā kolorektālā vēža skrīninga programmā. Materiāli un metodes. Tika izveidota neanonīma, pašaizpildāma, papīra formātā anket…
