Energy and momentum transfer in one-dimensional trapped gases by stimulated light scattering

In ultracold atoms settings, inelastic light scattering is a preeminent technique to reveal static and dynamic properties at nonzero momentum. In this work, we investigate an array of one-dimensional trapped Bose gases, by measuring both the energy and the momentum imparted to the system via light scattering experiments. The measurements are performed in the weak perturbation regime, where these two quantities-the energy and momentum transferred-are expected to be related to the dynamic structure factor of the system. We discuss this relation, with special attention to the role of in-trap dynamics on the transferred momentum.

Kiribilen kosmologia kuantikorako sarrera

Gradu amaierako lan hau kiribilen kosmologia kuantikorako sarrera bat da. Lan honek 4 kapi- tulu ditu. Lehenengoan, sarrera bezala grabitazio kuantikoak izan duen bilakaera historikoa jaso da, halako teoria bat garatzeko motibazioak eta zailtasunak, eta honen garapenean kosmologia kuantikoak duen papera azalduz. Lanean, oro har, grabitazio kuantikoaren teoria bat eraikitzeko formalismo “kanonikoa” jarraitu da, alegia, erlatibitate orokorraren formulazio hamiltondarra era- biliz teoria kuantikoa garatzea. Bigarren kapituluan grabitazioaren teoria klasikoaren formulazio hamiltondarra garatu da, lehenik Arnowitt-Deser-Misner formalismoaren (Einstein-en geometro- dinamika bezala ere ezaguna denaren) bidez eta ondoren Ashtekar-en aldagaiak erabiliz. Bietan hamiltondar guztiz lotua lortzen da, hots, loturen konbinazio lineala den hamiltondarra. Lotu- ren bidezko formulazio hauen kuantizazioaren eta kribilen adierazpenaren oinarrizko aspektuak jaso dira bigarren kapituluan. Hirugarren kapituluan kosmologiaren teoria klasikoa Friedmann- Lemaˆ ıtre-Robertson-Walker metrika laua erabiliz azaltzen da era laburrean lehenik, eta ondoren Wheeler-DeWitt teoria kuantikoa eta kiribilen kosmologia kuantikoa eta hauek erabiliz lorturiko zenbait emaitza aipatzen dira. Azkenik, ondorioen atalarekin amaitzen da lana. Lana euskaraz idatzita dago.

Inflammatory Markers and Obstructive Sleep Apnea in Obese Children: The NANOS Study

Introduction. Obesity and obstructive sleep apnea syndrome (OSA) are common coexisting conditions associated with a chronic low-grade inflammatory state underlying some of the cognitive, metabolic, and cardiovascular morbidities. Aim. To examine the levels of inflammatory markers in obese community-dwelling children with OSA, as compared to no-OSA, and their association with clinical and polysomnographic (PSG) variables. Methods. In this cross-sectional, prospective multicenter study, healthy obese Spanish children (ages 4-15 years) were randomly selected and underwent nocturnal PSG followed by a morning fasting blood draw. Plasma samples were assayed for multiple inflammatory markers. Results. 204 children were enrolled in the study; 75 had OSA, defined by an obstructive respiratory disturbance index (RDI) of 3 events/hour total sleep time (TST). BMI, gender, and age were similar in OSA and no-OSA children. Monocyte chemoattractant protein-1 (MCP-1) and plasminogen activator inhibitor-1 (PAI-1) levels were significantly higher in OSA children, with interleukin-6 concentrations being higher in moderate-severe OSA (i.e., AHI > 5/hrTST; P < 0.01), while MCP-1 levels were associated with more prolonged nocturnal hypercapnia (P < 0.001). Conclusion. IL-6, MCP-1, and PAI-1 are altered in the context of OSA among community-based obese children further reinforcing the proinflammatory effects of sleep disorders such as OSA. This trial is registered with ClinicalTrials.gov NCT01322763.

Quantum Emulation of Gravitational Waves

Gravitational waves, as predicted by Einstein's general relativity theory, appear as ripples in the fabric of spacetime traveling at the speed of light. We prove that the propagation of small amplitude gravitational waves in a curved spacetime is equivalent to the propagation of a subspace of electromagnetic states. We use this result to propose the use of entangled photons to emulate the evolution of gravitational waves in curved spacetimes by means of experimental electromagnetic setups featuring metamaterials.

"Heroes" and "Villains" of World History across Cultures

Emergent properties of global political culture were examined using data from the World History Survey (WHS) involving 6,902 university students in 37 countries evaluating 40 figures from world history. Multidimensional scaling and factor analysis techniques found only limited forms of universality in evaluations across Western, Catholic/Orthodox, Muslim, and Asian country clusters. The highest consensus across cultures involved scientific innovators, with Einstein having the most positive evaluation overall. Peaceful humanitarians like Mother Theresa and Gandhi followed. There was much less cross-cultural consistency in the evaluation of negative figures, led by Hitler, Osama bin Laden, and Saddam Hussein. After more traditional empirical methods (e.g., factor analysis) failed to identify meaningful cross-cultural patterns, Latent Profile Analysis (LPA) was used to identify four global representational profiles: Secular and Religious Idealists were overwhelmingly prevalent in Christian countries, and Political Realists were common in Muslim and Asian countries. We discuss possible consequences and interpretations of these different representational profiles.
