BACKGROUND Pulmonary function is impaired during pneumoperitoneum mainly as a result of atelectasis formation. We studied the effects of 10 cm H2O of positive end-expiratory pressure (PEEP) and PEEP followed by a recruitment maneuver (PEEP+RM) on end-expiratory lung volume (EELV), oxygenation and respiratory mechanics in patients undergoing laparoscopic surgery. METHODS Sixty consecutive adul...

ABSTRACT In this work, we have implemented a detailed physical model of galaxy chemical enrichment into the Astraeus (seminumerical rAdiative tranSfer coupling formaTion and Reionization in N-body dark matter simUlationS) framework which couples formation reionization first billion years. Simulating galaxies spanning over 2.5 orders magnitude halo mass with $M_{\rm h} \sim 10^{8.9}{-}10^{11.5}\...

We present near-IR photometry and spectroscopy of 30 extremely luminous radio mid-IR selected galaxies. With bolometric luminosities exceeding $\sim10^{13}$ $\rm{L_{\odot}}$ redshifts ranging from $z = 0.880-2.853$, we use VLT instruments X-shooter ISAAC to investigate this unique population Broad multi-component emission lines are detected in 18 galaxies measure the $\rm{H\rm{\beta}}$, $\text{...

150 words Memory for a past event involves remembering the various components of the event (item memory; IM), as well the associations or links formed between the components (relational memory; RM). Research studies using animal models, neuropsychological studies of human amnesic patients, and functional neuroimaging investigations have shaped our understanding of the cognitive and neural mecha...

We present AT2020mrf (SRGe J154754.2$+$443907), an extra-galactic ($z=0.1353$) fast blue optical transient (FBOT) with a rise time of $t_{g,\rm rise}=3.7$ days and peak luminosity $M_{g,\rm peak}=-20.0$. Its spectrum around shows broad ($v\sim0.1c$) emission feature on continuum ($T\sim2\times10^4$ K), which bears striking resemblance to AT2018cow. bright radio ($\nu L_\nu = 1.2\times 10^{39}\,...

ABSTRACT We examine the column density distribution function (CDDF) and Doppler parameter from hydrodynamical simulations Cosmic Origins Spectrograph (COS) observations of Ly α forest at redshift 0 ≤ z 0.2. Allowing for a factor two uncertainty in metagalactic H $\, \rm \scriptstyle I \, $ photoionization rate, our are good agreement (1–1.5σ) with shape amplitude observed CDDF densities $10^{13...

We provide a general framework to remove short advice by formulating the following computational task for a function f : given two oracles at least one of which is honest (i.e. correctly computes f on all inputs) as well as an input, the task is to compute f on the input with the help of the oracles by a probabilistic polynomial-time machine, which we shall call a selector. We characterize the ...
