Comprehensive Analyses of the Strongly Carbon-chain Depleted Comets in Lowell Observatory’s Narrowband Photometry Database

open access: yesThe Planetary Science Journal
We present measurements, analyses, and results for the 17 strongly carbon-chain depleted comets in Lowell Observatory’s narrowband photometry database.

Research of effect of initial data displacement on results of calculation of orbits evolution for short-period comets

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
We study the problems of stability of solution and the effect of initial data errors on the results of calculation of orbits evolution for short-period comets on the time intervals within the order of 100 years.

Phase Curves of Kuiper Belt Objects, Centaurs, and Jupiter-family Comets from the ATLAS Survey

open access: yesThe Planetary Science Journal, 2023
The Kuiper Belt objects (KBOs), the Centaurs, and the Jupiter-family comets (JFCs) form an evolutionary continuum of small outer solar system objects, and their study allows us to gain insight into the history and evolution of the solar system. Broadband

Dielectric Elastomer Actuators as Safe and Effective Tools for Mechanostimulation of Human Cells

open access: yesAdvanced Intelligent Systems, EarlyView.
Replicating physiological forces is crucial for realistic cell models. Dielectric elastomer actuators (DEAs) offer a soft alternative, though their high voltages raised toxicity concerns. We demonstrate that DEA stimulation causes no cell damage, cell death or cell‐cycle disruption, while activating mechanosensitive responses.

On the dynamics of short-period comets

open access: yes, 1987
Численно изучена эволюция орбит наблюдавшихся короткопериодических комет на промежутках времени до 50 000 лет. Рассмотрены особенности их либрационного и стохастического движения.

Dust On, Dust Off: HST Observations of the Newly Dormant Jupiter Co-orbital Comet P/2023 V6 (PANSTARRS)

open access: yesThe Planetary Science Journal
As the Centaurs of the outer solar system have become better studied, their relationship with the Jupiter-family comets (JFCs) and their connection to the primordial protoplanetary disk have come under deeper scrutiny: which properties of the comets ...

Influence of Storage Time on Functional Bulk Properties of Low‐Pressure Oxygen/Argon Plasma Modified Polypropylene Fabric

open access: yesJournal of Applied Polymer Science, EarlyView.
Treatment of polypropylene fabric in oxygen plasma was used to impart the fabric surface with more hydrophilic surface properties. Changes in bulk properties were minimal as the modification mainly affected the fabric surface. Bulk fabric properties water retention, moisture content and wicking were monitored over a period of 33 days.

Gas Sources from the Coma and Nucleus of Comet 46P/Wirtanen Observed Using ALMA

open access: yesThe Astrophysical Journal, 2023
Gas-phase molecules in cometary atmospheres (comae) originate primarily from (1) outgassing by the nucleus, (2) sublimation of icy grains in the near-nucleus coma, and (3) coma (photo)chemical processes.

Statistical and numerical studies of the orbital evolution of short-period comets [PDF]

open access: yesInternational Astronomical Union Colloquium, 1985
AbstractThe evolutionary paths connecting cometary reservoirs in the outer solar system and the population of periodic comets involve stellar and planetary perturbations. Close planetary encounters play a special role, making the dynamical evolution slow or fast depending on the orbital elements of the comet at various stages of the process.

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.
