Computing temporal sequences associated with dynamic patterns on the C. elegans connectome
2021
AbstractUnderstanding how the structural connectivity of a network constrains the dynamics it is able to support is a very active and open area of research. We simulated the plausible dynamics resulting from the known C. elegans connectome using a recent model and theoretical analysis that computes the dynamics of neurobiological networks by focusing on how local interactions among connected neurons give rise to the global dynamics in an emergent way, independent of the biophysical or molecular details of the cells themselves. We studied the dynamics which resulted from stimulating a chemosensory neuron (ASEL) in a known feeding circuit, both in isolation and embedded in the full connectome…
Elegancia, comodidad, belleza
2009
Accarezzare i luoghi del progetto, guardare verso la storia per configurare gli spazi del presente, predisporre ambiti di vita in cui la dignità del lavoro possa trovare con naturalezza la misura del proprio essere. Questi paradigmi Ignazio Gardella articola, attraverso l'uso magistrale ed elegante degli strumenti del progetto, nel rispondere, da militante professionista del mestiere di architetto, alla richiesta di un imprenditore “illuminato” quale fu Adriano Olivetti. Eleganza, comodità, qualità dell’architettura, bellezza estetica, delicato rapporto con il paesaggio contiguo, diventano un diritto che il progettista riconosce e consegna agli utenti, perchè lo esercitino liberamente, lont…
Is there a convincing case for climate veganism?
2020
AbstractClimate change compels us to rethink the ethics of our dietary choices and has become an interesting issue for ethicists concerned about diets, including animal ethicists. The defenders of veganism have found that climate change provides a new reason to support their cause because many animal-based foods have high greenhouse gas emissions. The new style of argumentation, the ‘climatic argument(s) for veganism’, may benefit animals by persuading even those who are not concerned about animals themselves but worry about climate change. The arguments about the high emissions of animal-based food, and a resulting moral obligation to abstain from eating such products, are an addition to t…

Franču eklektika Latvijas dzīvojamā telpā
2021
Diplomdarbs “Franču eklektika Latvijas dzīvojamā telpā” sastāv no trīm nodaļām. Pirmajā nodaļā, analizējot pieejamo literatūru un informācijas avotus, tiek aprakstīta Franču interjera vēsturē, un tā ietekme uz Franču eklektiskā stila veidošanas. Empīriskajā daļā tiek veikts salīdzinošais pētījums par Franču eklektikas atbilstošiem dzīvokļu interjeriem Francijā un Maskavā. Radošajā daļā tiek izstrādāts interjera projekts atbilstoši Franču stila nosacījumiem, balstoties uz teorētiskajā un empīriskajā daļā izdarītajiem secinājumiem.
Temporal genetic structure in a poecilogonous polychaete: the interplay of developmental mode and environmental stochasticity
2014
Background: Temporal variation in the genetic structure of populations can be caused by multiple factors, including natural selection, stochastic environmental variation, migration, or genetic drift. In benthic marine species, the developmental mode of larvae may indicate a possibility for temporal genetic variation: species with dispersive planktonic larvae are expected to be more likely to show temporal genetic variation than species with benthic or brooded non-dispersive larvae, due to differences in larval mortality and dispersal ability. We examined temporal genetic structure in populations of Pygospio elegans, a poecilogonous polychaete with within-species variation in developmental m…
Syntaxonomic survey of the class Pegano harmalae‐Salsoletea vermiculatae Br.‐Bl. & O. Bolos 1958 in Italy
2013
After a general outline on the syntaxonomical framework of the class Pegano harmalae-Salsoletea vermiculatae Br.-Bl. & O. Bolos 1958, the occurrence of this vegetation in the Italian territory is examined. In Italy, this vegetation is mostly found on clayish or marly substrata, particularly if slightly enriched with nitrates and chlorides. With reference to the Rivas-Martinez bioclimatic classification, the Italian stands have an infra- to thermo-Mediterranean thermotype (marginally up to the meso-Mediterranean one) with dry or arid ombrotype. In particular, this vegetation is well represented in Sicily, while in Sardinia and along the Italian Peninsula, it progressively becomes more rare a…
Generative adversarial networks with bio-inspired primary visual cortex for Industry 4.0
2022
Biologicalization (biological transformation) is an emerging trend in Industry 4.0 affecting digitization of manufacturing and related processes. It brings up the next generation of manufacturing technology and systems that extensively use biological and bio-inspired principles, materials, functions, structures and resources. This research is a contribution to the further convergence of computer and human vision for more robust and accurate automated object recognition and image generation. We present VOneGANs, a novel class of generative adversarial networks (GANs) with the qualitatively updated discriminative component. The new model incorporates a biologically constrained digital primary…
Itsessään arvokkaan rajoista : itsessään arvokkaasta, ihmiskeskeisyydestä ja ristiriitatilanteista Tom Reganin ja Paul Taylorin ajattelussa
2014
Tutkimuksen tarkoituksena on tarkastella Tom Reganin teoriaa itseisarvoisista olennoista ja tilanteista, joissa itseisarvoista olentoa onkin esimerkiksi hyväksyttävää vahingoittaa. Reganin teoriaa tarkastellaan sekä itseisarvolle asetettujen kriteerien mahdollisen ihmiskeskeisyyden että ristiriitatilanteiden ratkaisukeinojen kautta (ristiriitatilanteella viitataan tilanteeseen, jossa joudumme asettamaan vastakkain esimerkiksi kahden yhtäläisen arvokkaan yksilön yhtäläisen hyvinvoinnin). Reganin teorian vastapainona toimii Paul Taylorin ympäristöeettinen teoria, sillä Reganin eritellessä tietyt karkeat kriteerit "oman elämänsä subjekteiksi" kutsumilleen yksilöille, jotka ovat varmuudella its…
IP 3 signalling regulates exogenous RNA i in C aenorhabditis elegans
2015
RNA interference (RNAi) is a widespread and widely exploited phenomenon. Here, we show that changing inositol 1,4,5-trisphosphate (IP3) signalling alters RNAi sensitivity in Caenorhabditis elegans. Reducing IP3 signalling enhances sensitivity to RNAi in a broad range of genes and tissues. Conversely up-regulating IP3 signalling decreases sensitivity. Tissue-specific rescue experiments suggest IP3 functions in the intestine. We also exploit IP3 signalling mutants to further enhance the sensitivity of RNAi hypersensitive strains. These results demonstrate that conserved cell signalling pathways can modify RNAi responses, implying that RNAi responses may be influenced by an animal's physiology…
