Innovative Mechanical Design Strategy for Actualizing 80 kg-Class X-Band Active SAR Small Satellite of S-STEP

open access: yesAerospace, 2021
The Small SAR Technology Experimental Project (S-STEP) mission aims to develop a new (space-based 80 kg-class active X-band synthetic aperture radar (SAR)) satellite with a main imaging mode of 1 m resolution stripmap.

The impact of increasing stratospheric radiative damping on the quasi-biennial oscillation period [PDF]

open access: yesAtmospheric Chemistry and Physics, 2021
Stratospheric radiative damping increases as atmospheric carbon dioxide concentration rises. We use the one-dimensional mechanistic models of the quasi-biennial oscillation (QBO) to conduct sensitivity experiments and find that the simulated QBO period ...

Single Event Upsets Under Proton, Thermal, and Fast Neutron Irradiation in Emerging Nonvolatile Memories

open access: yesIEEE Access, 2022
In New Space, the need for reduced cost, higher performance, and more prompt delivery plans in radiation-harsh environments have motivated spacecraft designers to use Commercial-Off-The-Shelf (COTS) memories and emerging technology devices.

New Ideas Need New Space [PDF]

open access: yesSSRN Electronic Journal, 2000
We develop a setting with weak intellectual property rights, where firms' boundaries, location and knowledge spillovers are endogenous. We have two main results. The first one is that, if communication costs increase with distance, entrepreneurs concerned about information leakage have a benefit from locating away from the industry center: distance is ...

CMIP6 Historical Simulations (1850–2014) With GISS‐E2.1

open access: yesJournal of Advances in Modeling Earth Systems, 2021
Simulations of the CMIP6 historical period 1850–2014, characterized by the emergence of anthropogenic climate drivers like greenhouse gases, are presented for different configurations of the NASA Goddard Institute for Space Studies (GISS) Earth System ...

Background subtraction for the Cluster/CODIF plasma ion mass spectrometer [PDF]

open access: yesGeoscientific Instrumentation, Methods and Data Systems, 2014
The CODIF instrument on the Cluster spacecraft is a time-of-flight (TOF) ion mass spectrometer. Although TOF spectrometers are relatively immune to background contamination due to the inherent double coincidence requirement, high background rates can ...

NEW APPROACHES ON DUAL SPACE [PDF]

open access: yesFacta Universitatis, Series: Mathematics and Informatics, 2020
In this paper, we give how to define the basic concepts of differential geometry on Dual space. For this, dual tangent vectors that have p as dual point of application are defined. Then, the dual analytic functions defined by Dimentberg are examined in detail, and by using the derivative of the these functions, dual directional derivatives and dual ...

Phosphoinositides in New Spaces

open access: yesCold Spring Harbor Perspectives in Biology, 2023
Phosphoinositides (PIs) are phospholipids derived from phosphatidylinositol. PIs are regulated via reversible phosphorylation, which is directed by the opposing actions of PI kinases and phosphatases. PIs constitute a minor fraction of the total cellular lipid pool but play pleiotropic roles in multiple aspects of cell biology.

Investigating the Magnetic Structure of Interplanetary Coronal Mass Ejections Using Simultaneous Multispacecraft In Situ Measurements

open access: yesThe Astrophysical Journal, 2023
In situ measurements from spacecraft typically provide a time series at a single location through coronal mass ejections (CMEs), and they have been one of the main methods to investigate CMEs.
