Reexamining the Power-law Relationship between Global Solar X-Ray Luminosity and Total Unsigned Magnetic Flux

open access: yesThe Astrophysical Journal
The mechanism heating the solar corona remains unclear but is generally hypothesized to involve magnetic fields. One probe of this hypothesis is a statistical study relating coronal emission to magnetic flux. A. A. Pevtsov et al.

Physically unclonable functions in digital integrated circuits

open access: yesРоссийский технологический журнал
Objectives. Modules that implement physically unclonable functions (PUFs) within a digital chip facilitate the direct use of challenge–response pairs by device applications that can query and read the PUF without external tools or exposing data outside ...

Synoptic Maps of CaII K line intensity based on observations from MWO (1915-1985)

open access: yes
This dataset contains Carrington synoptic maps of Ca II 393.4 nm intensity for the years 1915-1985. These maps are produced using Mount Wilson Observatory calcium K-line images.

Temporal and Structural Properties of Sunspot Small Short-living Group and Large Long-living Group Populations

open access: yesThe Astrophysical Journal
We investigate the properties of two types of solar active regions: the small short-living groups (SSGs) and the large long-living groups (LLGs). The combined distribution of areas of active regions is bimodal. When deconvolved, the distributions of each

METHODOLOGY FOR VERIFYING THE CHIP AUTHENTICITY BASED ON DYNAMIC ENERGY CONSUMPTION ANALYSIS

open access: yesБезопасность информационных технологий
In the conditions of restructuring and complication of logistic supply chains of EKB (Electronic Component Base) the risk of supplying counterfeit products increases significantly, which determines the relevance of the development of simple and cost ...

Severe Hypofunction of Allogeneic Hematopoietic Stem Cell Transplant in Patients with Oncohematological Diseases: Incidence, Risk Factors, and Outcomes

open access: yesКлиническая онкогематология, 2019
Aim. Based on strict criteria, to assess incidence, pretransplantation risk factors, and outcomes of severe hypofunction of graft, i.e. poor graft function (sPGF), following allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adults ...

HK_Project_v1995_NSO

open access: yes
This dataset is for the historic Mount Wilson Observatory HK Project, which aimed at studying stellar chromospheric activity and variability. What appears to be a complete, calibrated, and self-consistent copy of the processed data for almost 2300 HK ...

HK_Project_v2001_NSO

open access: yes
In addition to the 1995 archive, data for 35 stars (essentially, the stars from Lockwood et al. 2007, plus a few additional stars) are included in this release. These observations typically extend through late 2001, i.e., they lack only the final year’s

Synoptic maps from different Lagrangian points

open access: yes
The synoptic maps of pseudo-radial magnetic field as if there observed from Lagrangian points L1, L1+L5, L1+L5+l4, L1+L5+L4+L3, L1+SolO out of ecliptic location, and true magnetic field used for creating these synoptic maps.
