Synchronizing Two Superconducting Qubits through a Dissipating Resonator
2021
A system consisting of two qubits and a resonator is considered in the presence of different sources of noise, bringing to light the possibility of making the two qubits evolve in a synchronized way. A direct qubit–qubit interaction turns out to be a crucial ingredient, as well as the dissipation processes involving the resonator. The detrimental role of the local dephasing of the qubits is also taken into account.

DEEP TISSUE MASSAGE AND FLEXIBILITY IN THE STRUCTURAL COMPONENTS OF THE SUPERFICIAL BACK LINE OF PROFESSIONAL VOLLEYBALL PLAYERS: A PILOT STUDY
2019
Background: Massage is a common treatment in physiotherapy, often used as a prophylaxis or during recovery following a musculoskeletal contusion. One form of therapeutic massage is deep tissue massage (DTM), which has become more popular in recent years as a way of performing targeted work with the myofascial system. Aim of the study: The aim of the study was to examine the effectiveness of deep tissue massage on superficial back line flexibility (hip flexion and knee extension range of motion - ROM). Material and methods: Elite volleyball players (n=15), age: 22.8 ± 4.41 years; mass: 82.67 ± 6.99 kg; height: 1.96 ± 0.08 m) were recruited for this study. Deep tissue massage of the myofascia…
Dalītā īpašuma tiesisko attiecību problemātika.
2018
Dalītā īpašuma tiesisko attiecību problemātika ir daļa no Latvijas unikālās tiesību sistēmas, kur viens no būtiskākajiem un praksē neskaidrību raisošiem problēmjautājumiem ir piespiedu zemes nomas maksas apmēra noteikšana. Darba mērķis ir identificēt piespiedu zemes nomas maksas apmēra noteikšanas mehānisma problēmas un ierosināt turpmākai rīcībai nepieciešamās darbības taisnīga regulējuma izstrādei piespiedu nomas attiecībās. Pētījuma rezultātā noskaidrots, ka par atsevišķiem piespiedu zemes nomas maksas apmēra noteikšanas kritērijiem joprojām nav izveidojusies vienveidīga tiesu prakse, kas liecina par normatīvā regulējuma deficītu šajā jomā. Līdz ar to Latvijā ir nepieciešams pilnveidot p…
Apziņas ontoloģija D.Čalmera un Dž.Serla koncepcijās: salīdzinoša analīze
2018
Darba centrālais priekšmets ir ķermeņa un prāta nošķīruma problēma, kas paredz fizikālo un mentālo procesu kauzālo attiecību skaidrojuma nepieciešamību. Iesākumā būs Dž.Serla bioloģiskā naturālisma teorijas izklāsts, kas, nenoliedzot pirmās personas ontoloģiju, definē apziņu kā nereducējamu fizikālu sistēmas īpašību, vienlaicīgi pasludinot sarežģītās problēmas neesamību, kuras pamatā ir aplams konceptuāla duālisma nošķīrums. Tālāk sekos D.Čalmera argumenta restaurācija, kas ir mēģinājums atspēkot fizikālismu, apstrīdot apziņu kā loģiski superventu īpašību, lai leģitimētu naturālistisku funkcionāla duālisma teoriju. Savukārt pēdējā nodaļā abu autoru savstarpēja diskusija ļauj saprast atšķirī…
Deuil et narration à partir du malade en phase terminale. Repères anthropologiques et philosophiques pour l'accompagnement des personnes en fin de vi…
2020
El duelo corresponde a sentimientos individuales y colectivos relativos a la pérdida y la muerte. Es un concepto polisémico cuya aprehensión apela diversas ramas de conocimiento, como la psicología, el psicoanálisis, la historia, la antropología, la filosofía, etc. Se puede abrir su comprensión a otras realidades más englobantes, como la situación de enfermedad terminal, la muerte inminente, o todo tipo de pérdidas significativas en la existencia humana. El duelo es un fenómeno de la condición humana e interesa a cada cual, independientemente de su cultura, su época o la edad. Se refiere a la vivencia de un individuo determinado, confrontado a su estado de finitud, y expresa el “malestar” q…
Surfactant self-assembling in the gas phase: bis(2-ethylhexyl)- sulfosuccinate divalent metal ion anionic aggregates
2012
RATIONALE: Investigation of fundamental aspects driving surfactant self-assembling and of the capability of including guest molecules or ions in their micellar aggregates is an exciting research field for theoretical and technological reasons. In this light, assembling and chelating properties of sodium bis(2-ethylhexyl)sulfosuccinate (AOTNa) towards divalent metal ion chlorides have been investigated in the gas phase by electrospray ionization mass spectrometry in negative ion mode, tandem mass spectrometry and energy-resolved mass spectrometry. METHODS:Water/methanol solutions of AOTNa and chloride salts of nickel, magnesium, calcium and manganese, with different AOTNa/metal salt ratios, …
Gas Phase Charged Aggregates of Bis(2-ethylhexyl)sulfo-succinate (AOT) and Divalent Metal Ions. First evidence of AOT solvated aggregates
2011
Assembling and chelating properties of sodium bis(2-ethylhexyl)sulfosuccinate (AOTNa) towards divalent metal ions have been investigated in the gas phase by electrospray ionization mass spectrometry. A variety of positively charged monometallated and mixed metal aggregates are formed. Interestingly, several ions contain solvent (MeOH, H2O) molecules and constitute the most abundant AOT cationic aggregates not containing sodium. These species are the first example of solvated AOT-metal ion aggregates in the gas phase. By increasing the surfactant aggregation number, the abundance of solvated species becomes lower than that of unsolvated ones. Decompositions of ionic species have been studied…
Do electrospray mass spectra of surfactants mirror their aggregation state in solution?
2011
One important feature in the gas phase chemistry of surfactants is to ascertain whether their aggregates produced by electrospray ionization reflect those formed in the starting solution. With this aim, we have performed ESI-MS, ESI-MS/MS and ER-MS spectra of bis(2-ethylhexyl)sulfosuccinate (AOTNa) solutions in different solvents, i.e. water, water/methanol, methanol and n-hexane. The results clearly indicate that, notwithstanding the strongly different aggregation state in solution (direct micelles in water and in water/methanol, molecular dispersion in methanol and reverse micelles in n-hexane) and marked effects of the solvent polarity on the total ionic current, the surfactant aggregate…
