Skaalainvarianssi kvanttimekaniikassa
2013
Tässä tutkielmassa tarkastellaan klassisesti skaalainvarianttia systeemiä kvanttimekaniikan keinoin. Lähtökohdaksi otetaan klassinen mekaniikka, ja tarkastelemalla vaikutusintegraalia todetaan, että ainoa systeemin skaalainvarianssin takaava potentiaali on muotoa D/r^2, missä D on vakio. Tämän jälkeen siirrytään ratkaisemaan Schrödingerin yhtälöä kyseiselle potentiaalille. Ensiksi huomataan, että dimensioanalyysin perusteella sidottuja tiloja esittäviä ratkaisuja ei voi olla. Lisäksi havaitaan negatiivisia energioita vastaavien tilojen olevan ongelmallisia. Nämä ongelmat asetetaan kuitenkin sivuun, ja ratkaistaan ominaisarvo-ongelma suoraviivaisesti. Tuloksena saadaan negatiivisille energio…
Cyano-Phycocyanin: Mechanisms of Action on Human Skin and Future Perspectives in Medicine
2022
Cyano-phycocyanin is one of the active pigments of the blue-green algae and is usually isolated from the filamentous cyanobacteria Arthrospira platensis Gomont (Spirulina). Due to its multiple physiological functions and non-toxicity, cyano-phycocyanin may be a potential substance for the topical treatment of various skin diseases. Considering that the conventional medicine faces drug resistance, insufficient efficacy and side effects, the plant origin compounds can act as an alternative option. Thus, the aim of this paper was to review the wound healing, antimicrobial, antioxidative, anti-inflammatory, antimelanogenic and anticancer properties and mechanisms of cyano-phycocyanin topical ac…
Excessive Daytime Sleepiness in Obstructive Sleep Apnea Patients Treated With Continuous Positive Airway Pressure: Data From the European Sleep Apnea…
2021
Excessive daytime sleepiness (EDS) is a symptom of obstructive sleep apnea (OSA) that resolves under treatment with continuous positive airway pressure (CPAP). In some patients, sleepiness persists despite CPAP treatment. We retrospectively analyzed data on subjective residual EDS, assessed as an Epworth Sleepiness Scale score (ESS) >10, in patients from the European Sleep Apnea Database (n = 4,853, mean age +/- SD 54.8 +/- 11.8 years, 26.1% females), at baseline and at the first visit (median follow-up: 5 months, interquartile range 3-13). An ESS > 10 occurred in 56% of patients at baseline and in 28.2% of patients at follow-up. Residual EDS was analyzed in 2,190 patients (age: 55.1 +/- 12…
miRNome Profiling Detects miR-101-3p and miR-142-5p as Putative Blood Biomarkers of Frailty Syndrome
2022
Frailty is an aging-related pathology, defined as a state of increased vulnerability to stressors, leading to a limited capacity to meet homeostatic demands. Extracellular microRNAs (miRNAs) were proposed as potential biomarkers of various disease conditions, including age-related pathologies. The primary objective of this study was to identify blood miRNAs that could serve as potential biomarkers and candidate mechanisms of frailty. Using the Fried index, we enrolled 22 robust and 19 frail subjects. Blood and urine samples were analysed for several biochemical parameters. We observed that sTNF-R was robustly upregulated in the frail group, indicating the presence of an inflammatory state. …
Commentary: Long-term Practice with Domain-Specific Task Constraints Influences Perceptual Skills.

Palermo senziente. Città di persone e città di sensori
2021
Nel mondo contemporaneo, razionalità e percezione non nascono più nella mente e nei sensi umani. Un recente libro curato da Grazia Concilio e Francesca Rizzo mostra numerose sfaccettature di questa questione. Quando nel 2017 Maurizio Carta introduce il concetto di città senziente, rafforza significativamente le basi per integrare ragione e sentimento urbanistico, cioè per integrare la razionalità della conoscenza strutturata e finalizzata al processo di pianificazione con le percezioni derivanti dalla “pancia” della città. Il contributo propone una visione innovativa sulla dualità analitica e valutativa che si genera tra mondo reale e mondo digitale, tra gli abitanti-utenti delle città e gl…
Characterization of IP-Based Communication for Smart Grid Using Software-Defined Networking
2018
The smart grid (SG) approach is based on a strong interaction between the network communication infrastructure and the power grid. Usually the management of the infrastructure is done by the distribution system operators (DSOs) that are worried about the increasing managing complexity due to the presence of increasing number of distributed energy resources and electrical vehicles. The use of software-defined networking (SDN) may simplify the network configuration and management for DSO, as highlighted from previous research works. The objective of this paper is to introduce and characterize an internet protocol (IP)-based communication architecture with specialized SDN bridges operating als…
Aristóteles entre doxografía y biografía: sobre Diógenes Laercio V 31
2019
Se pretende llamar la atención sobre un par de frases que aparecen justo hacia la mitad de la controvertida doxografía de Aristóteles que se puede leer en las Vidas y doctrinas de los filósofos más ilustres de Diógenes Laercio V 31, y que desde luego no corresponden a ningún sistema doxográfico conocido. Como sucede no pocas veces en la obra laerciana, la misma apreciación sobre si el filósofo debe o no enamorarse y contraer matrimonio se repite idéntica en otras doxografías completamente distintas: la cirenaica (DL II 91), la estoica (DL VII 129) y la epicúrea (DL X 118). Cabe plantearse, pues, el origen de este interés, en varias doxografías, por la vida sentimental, podríamos decir, de l…
EDM and Ecstasy: the lived experiences of electronic dance music festival attendees
2017
Attendance at large-scale music festivals has captivated a global interest in these spectacular experiences, yet little is known about the lasting benefits and personal changes individuals incur following this event. This study aims to provide a comprehensive exploration of the lived experiences of individuals who attended a multi-day electronic dance music festival. The present study was primarily interested in the perceived beneficial changes within the individual, following their festival experience. We investigated if first-time festival attendees perceived changes differed to those of returning individuals. Semi-structured qualitative interviews were used to collect data from 12 indivi…
