The Perseus ALMA Chemistry Survey (PEACHES). II. Sulfur-bearing Species and Dust Polarization Revealing Shocked Regions in Protostars in the Perseus Molecular Cloud

The Astrophysical Journal, 2023
In protostellar cores, sulfur species are effective probes for the energetic environments, such as shocked regions. With the majority of sulfur depleted on dust grains, sulfur-bearing molecules could be liberated back to gas phase by shocks associated ...

Domain-specific p53 mutants activate EGFR by distinct mechanisms exposing tissue-independent therapeutic vulnerabilities

Nature Communications, 2023
Here the authors identify distinct mechanisms by which domain-specific p53 mutations activate cancer cell growth via the epidermal growth factor receptor (EGFR). These mechanisms affect sensitivity to EGFR inhibitors, opening avenues for targeted therapy.

Early-forming Massive Stars Suppress Star Formation and Hierarchical Cluster Assembly

The Astrophysical Journal, 2023
Feedback from massive stars plays an important role in the formation of star clusters. Whether a very massive star is born early or late in the cluster formation timeline has profound implications for the star cluster formation and assembly processes. We

Performance Evaluation of Beacon-Enabled Mode for IEEE 802.15.4 Wireless Sensor Network

Emitter: International Journal of Engineering Technology, 2013
IEEE 802.15.5 standard support structure of star and peer-to-peer network formation. Strating from these, the cluster tree network can be built as a special case of peer-to-peer network to increse coverage area.

VERTICO. VII. Environmental Quenching Caused by the Suppression of Molecular Gas Content and Star Formation Efficiency in Virgo Cluster Galaxies

The Astrophysical Journal, 2023
We study how environment regulates the star formation cycle of 33 Virgo Cluster satellite galaxies on 720 pc scales. We present the resolved star-forming main sequence for cluster galaxies, dividing the sample based on their global H i properties and ...

Bruck 88 : a young star cluster with an old age resemblance in the outskirts of the Small Magellanic Cloud [PDF]

, 2014
We present spectroscopic and photometric results for the Small Magellanic Cloud (SMC) cluster Bruck 88. From the comparison of the cluster integrated spectrum with template cluster spectra we found that the Milky Way globular cluster template spectra are

Sub-clinical abnormalities detected by PET/MRI in household tuberculosis contacts

BMC Infectious Diseases, 2019
Background The understanding of early events following TB exposure is limited by traditional tests that rely on detection of an immune response to infection, which is delayed, or on imaging tests with low sensitivity for early disease.

Molecular Gas Properties in Young Stellar Clusters with a Suppressed Star Cluster Wind

The Astrophysical Journal Letters, 2023
In compact and dense star-forming clouds a global star cluster wind could be suppressed. In this case stellar feedback is unable to expel the leftover gas from the cluster. Young massive stars remain embedded in a dense residual gas and stir it by moving
