A Novel Sparse Cellular Labeling System with Tunable Gradients and Long‐Term Stability

Advanced Science, Volume 13, Issue 54, 28 September 2026.
The Tri‐M (Multi‐recombinase, Multi‐recognition site, and Multi‐nested) sparse cellular labeling system, built upon competitive recombination, integrates transgenic mice with viral injection to achieve tunable and long‐term stable sparse labeling of specific cell types with region selectivity, from sparse populations to individual cells, facilitating ...

Synthesis and Characterization of the Molybdenum Carbonyl‐Functionalized Zintl Ions [(η4‐Pb4)Mo(CO)3]4− and [Pb4{Mo(CO)3}3]6−

Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 13, 1 September 2026.
The reaction of the tetrahedral [Pb4]4− with Mo(CO)4(tmeda) yields two different Mo(CO)3‐functionalized clusters which can both be related to known clusters by the same substitution pattern following the isolobal principle. The crystal structures of [Na([2.2.2]crypt)]2Na2[(η4‐Pb4)Mo(CO)3] · 8.7NH3 and Na6[Pb4{Mo(CO)3}3] · 22NH3 are reported.

Supernova remnants and the origin of cosmic rays

, 2014
Supernova remnants have long been considered to be the dominant sources of Galactic cosmic rays. For a long time the prime evidence consisted of radio synchrotron radiation from supernova remnants, indicating the presence of electrons with energies of ...

Observations of Shell-Type Supernova Remnants with H.E.S.S.

, 2010
The bulk of the Galactic Cosmic Rays (with energies up to 101 5eV) is believed to be accelerated in the shock f ron rays, radiation which is produced in the interactions of accelerated protons with ambien tmaterial. On this poster we present a summary of

X-ray Polarimetry of Supernova Remnants

, 2021
Young supernova remnants such as Tycho, Cas A and SN1006 are relativistic particle accelerators and likely the sources of Galactic cosmic rays. In these sources X-ray synchrotron emitting regions, such as the shock fronts, have been identified and their ...

OBSERVATIONS OF NON TYPICAL MASERS AT THE RT-22 RADIO TELESCOPE IN 2004–2013

Radio Physics and Radio Astronomy, 2017
Purpose: Some peculiarities of emission of Class I methanol masers on the 80–71A+ transition at 95 GHz in sources closely associated with protostar-forming regions and in supernova remnants are studied.

A high sensitivity search for X-rays from supernova remnants in Aquila [PDF]

, 1972
A high sensitivity scan of the galactic plane was performed to search for 2-20 keV X-rays from supernova remnants. The spectra of five X-ray sources detected between 44 deg and 31 deg longitude, of which only two might be associated with suggested ...

The evolution of mass loaded supernova remnants

, 2002
We describe the evolution of spherically symmetric supernova remnants in which mass addition takes place from embedded clouds. We derive simple approximations to the remnant evolution which can be used for investigating the generation of supernova ...

INTERACTION OF SUPERNOVA BLAST WAVES WITH WIND-DRIVEN SHELLS: FORMATION OF

Odessa Astronomical Publications, 2017
Most of middle-aged supernova remnants (SNRs) have a distorted and complicated appearance which cannot be explained in the framework of the Sedov-Taylor model.

Long-slit optical spectroscopy of Large Magellanic Cloud radio supernova remnants

, 2008
We use long-slit spectra from shocked regions of radio supernova remnants (SNRs) in the Large Magellanic Cloud to estimate electron density and derive an average 'metal' abundance of 10-3.9 based on diagnostic line ratio plots.
