Patrones estructurales y funcionales de las comunidades de procariotas en humedales mediterráneos y su relación con el ciclo del carbono
2023
Las zonas húmedas mediterráneas juegan un papel muy importante en los ciclos biogeoquímicos, ya que la presencia de agua, de forma constante o transitoria, favorece unas altas tasas metabólicas. Respecto al ciclo del carbono, los humedales mediterráneos se ven activamente involucrados en la captación o en la emisión de gases de efecto invernadero carbonados (C-GEI) hacia la atmósfera, concretamente el dióxido de carbono y el metano. Esta relevancia de los humedales en el ciclo del carbono se debe, en parte, a la actividad de las comunidades de procariotas que habitan en el agua y en el sedimento de las zonas húmedas, puesto que la abundancia y versatilidad metabólica de los procariotas les …
A method for anomaly detection in hyperspectral images, using deep convolutional autoencoders
2017
Menetelmä poikkeavuuksien havaitsemiseen hyperspektrikuvista käyttäen syviä konvolutiivisia autoenkoodereita. Poikkeavuuksien havaitseminen kuvista, erityisesti hyperspektraalisista kuvista, on hankalaa. Kun ongelmaan yhdistetään ennalta tuntematon data ja poikkeavuudet, muodostuu ongelma vielä laajemmaksi. Spektraalisten poikkeavuuksien havaitsemiseen on kehitetty useita eri menetelmiä, mutta spatiaalisten poikkeavuuksien havaitseminen on huomattavasti hankalempaa. Tässä työssä esitellään uudenkaltainen menetelmä sekä spatiaalisten että spektraalisten poikkeavuuksien samanaikaiseen havaitsemiseen. Menetelmä on suunniteltu erityisesti spektraaliselle datalle, mutta soveltuu myös perinteisil…
Revision of Recent and fossil Mixtacandona Klie 1938 (Ostracoda, Candonidae) from Italy, with description of a new species
2017
Although studies on ostracods dwelling in inland subterranean habitats of Italy have increased in the last decades, highlighting a considerable taxonomic diversity, available information is still far from sufficient to understand phylogenetic and biogeographic relationships. Mixtacandona Klie 1938 is one of the most common and diverse genera of ostracods in subterranean waters. Of the 20 living recognized species in the genus, all stygobiontic and restricted to the Palearctic Region, four are known for the Italian peninsula and Sardinia, one of which exclusively as fossil. Several other Recent and fossil taxa attributable to Mixtacandona, but identified at supraspecific level, have been rep…
Molecular Pathways Implicated in Radioresistance of Glioblastoma Multiforme: What Is the Role of Extracellular Vesicles?
2023
Glioblastoma multiforme (GBM) is a primary brain tumor that is very aggressive, resistant to treatment, and characterized by a high degree of anaplasia and proliferation. Routine treatment includes ablative surgery, chemotherapy, and radiotherapy. However, GMB rapidly relapses and develops radioresistance. Here, we briefly review the mechanisms underpinning radioresistance and discuss research to stop it and install anti-tumor defenses. Factors that participate in radioresistance are varied and include stem cells, tumor heterogeneity, tumor microenvironment, hypoxia, metabolic reprogramming, the chaperone system, non-coding RNAs, DNA repair, and extracellular vesicles (EVs). We direct our a…
Frazeologizmy v demotivatorah
2008
The article presents new compound words, which are frequently a verbal component of internet polycode texts, i.e. demotivators. Demotivators, i.e. pictures combining graphics or photo and ironie commentary, were at first a response to motivational posters, whose task was to encourage people to work or learn. In the virtual world demotivators comment on current events or mock everyday nonsense. They are such a solidified genre that some of the commentaries used in demotivators can be perceived as phraseological neologisms.
Space-Frequency Quantization for Image Compression With Directionlets
2007
The standard separable 2-D wavelet transform (WT) has recently achieved a great success in image processing because it provides a sparse representation of smooth images. However, it fails to efficiently capture 1-D discontinuities, like edges or contours. These features, being elongated and characterized by geometrical regularity along different directions, intersect and generate many large magnitude wavelet coefficients. Since contours are very important elements in the visual perception of images, to provide a good visual quality of compressed images, it is fundamental to preserve good reconstruction of these directional features. In our previous work, we proposed a construction of critic…
From a Finnish player to an English avatar : language alternation in immersive video gaming sessions
2015
Videopelien pelaamisesta on tullut suosittu harrastus, joka sisältää usein aktiivista ja monikielistä kommunikointia pelaajien kesken. Pelaamisen sosiaalisuutta ja keskustelijoiden koodinvaihtoa käsittelevän tutkimuksen asetelmat ovat keskittyneet yhdellä ruudulla pelattaviin konsolipeleihin, vaikka internet on mahdollistanut etämoninpelaamisen ja ääniviestien välittämän vuorovaikutuksen. Kokemus virtuaaliseen maailmaan eläytymisestä voi muovata pelaajien välistä keskustelua, ja ilman kehonkieltä kielellisillä valinnoilla on pelaajien reaktioiden sekä hahmoihin samaistumisen ilmaisemisessa entistä suurempi rooli. Tämän tutkielman tarkoitus oli selvittää, mihin tarkoituksiin ja kuinka laajas…

eHealth Services and Technology : Challenges for Co-Development
2007
The promises of ICT have been poorly redeemed in health care; many projects have failed. This article conceptualizes the co-construction of services and technologies in order to help future practitioners in the field to understand and find solutions to the challenges in ICT-enhanced service change. The conceptualization is created by structuring the findings of a case study with the help of theoretical concepts. The conceptualization then is implemented in another case to study its potential for finding challenges and suggesting solutions. Both cases demonstrate challenges for codevelopment that contributed to poor project outcomes. Participants in eHealth projects need a better understandi…
Widespread Decoding of Tactile Input Patterns Among Thalamic Neurons
2021
Whereas, there is data to support that cuneothalamic projections predominantly reach a topographically confined volume of the rat thalamus, the ventroposterior lateral (VPL) nucleus, recent findings show that cortical neurons that process tactile inputs are widely distributed across the neocortex. Since cortical neurons project back to the thalamus, the latter observation would suggest that thalamic neurons could contain information about tactile inputs, in principle regardless of where in the thalamus they are located. Here we use a previously introduced electrotactile interface for producing sets of highly reproducible tactile afferent spatiotemporal activation patterns from the tip of di…
