Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Feedback shaped the galaxy morphological sequence in presence of mergers

open access: yesThe Open Journal of Astrophysics
Bulges and disks are major structural components that define galaxy morphology. The mass ratios of bulges and disks increase statistically with the galaxy mass, with the high-mass end occupied by elliptical galaxies. Although previous theoretical studies

Numerical simulations on the relative importance of starbursts and AGN in ultra-luminous infrared galaxies [PDF]

open access: yes, 2005
We investigate the relative importance of starbursts and AGN in nuclear activities of ultra-luminous infrared galaxies (ULIRGs) based on chemodynamical simulations combined with spectrophotometric synthesis codes.

Triaxiality in disk galaxies

open access: yesThe Astrophysical Journal, 1991
Thirty-two bulges of nearby spirals have been observed, to detect misalignment between disk and bulge apparent major axes. Such misalignment is unequivocally present in the majority of observed objects. This may be due to the triaxiality of disks, bulges, or both.

THE OPACITY OF SPIRAL GALAXY DISKS [PDF]

open access: yes, 2007
The opacity of foreground spiral disks can be probed from the number of distant galaxies seen through them. To calibrate this number for effects other than the dust extinction, Gonzalez et al. (1998) developed the "Synthetic Field Method". A synthetic field is an extincted Hubble Deep Field added to the science field.

THE PARKER INSTABILITY IN DISK GALAXIES [PDF]

open access: yesThe Astrophysical Journal, 2015
ABSTRACT We examine the evolution of the Parker instability in galactic disks using 3D numerical simulations. We consider a local Cartesian box section of a galactic disk, where gas, magnetic fields, and cosmic rays are all initially in a magnetohydrostatic equilibrium. This is done for different choices of initial cosmic-ray density and

Emergence and Genomic Characterization of a Hypervirulent Klebsiella pneumoniae Isolate From a New Clone in Brazil

open access: yesMicrobiology and Immunology, EarlyView.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) has emerged globally as a major public health concern, often associated with severe community‐acquired and healthcare‐associated human infections. Despite alerts from PAHO/WHO on convergent hvKp strains with multidrug resistance in Latin America, comprehensive data from Brazil, the region's largest ...

Noble gases and nitrogen in material from asteroid Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Comparing Galaxies and Lyman Alpha Absorbers at Low Redshift

open access: yes, 1997
A scenario is explored in which Lyman alpha absorbers at low redshift arise from lines of sight through extended galaxy disks, including those of dwarf and low surface brightness galaxies.
