EVOLUTION OF MASS OUTFLOW IN PROTOSTARS [PDF]
ABSTRACT We have surveyed 84 Class 0, Class I, and flat-spectrum protostars in mid-infrared [Si ii], [Fe ii], and [S i] line emission, and 11 of these in far-infrared [O i] emission. We use the results to derive their mass outflow rates, .

ABSTRACT Ulcerative colitis (UC) and Crohn's disease (CD) are increasingly prevalent in the Asia Pacific region, necessitating updated, region‐specific guidance on advanced therapies. Targeted small molecule agents, such as filgotinib, tofacitinib, upadacitinib, etrasimod, and ozanimod; and the IL‐23 p19 inhibitors (guselkumab, mirikizumab ...

The Role of Benzonitrile Chlorination Explored by Dissociative Electron Attachment
Experimental and theoretical dissociative electron attachment study of 2‐ and 4‐chlorobenzonitrile. The dissociative electron attachment process to ortho‐ and para‐chlorobenzonitrile was investigated in the 0–12 eV energy range with a crossed‐beam time‐of‐flight mass spectrometer, supported by quantum chemical scattering calculations.

Witnessing the birth of a supermassive protostar [PDF]
The detection of $\rm z>6$ quasars reveals the existence of supermassive black holes of a few $\rm 10^9~M_{\odot}$. One of the potential pathways to explain their formation in the infant universe is the so-called direct collapse model which provides massive seeds of $\rm 10^5-10^6~M_{\odot}$.

Small‐scale elemental abundance variations in Ryugu particles from touchdown 1
Abstract Ryugu materials closely resemble CI chondrites' mineralogical, chemical, and isotopic compositions; yet minor but resolvable differences in certain elemental abundances are evident. In this study, the bulk chemical compositions of eight individual Ryugu particles (1.5–4.3 mg) from the first touchdown site (TD1) were determined using triple ...

Characterizing Magnetic Properties of Young Protostars in Orion
The B -field Orion Protostellar Survey (BOPS) recently obtained polarimetric observations at 870 μ m toward 61 protostars in the Orion molecular clouds with ∼1″ spatial resolution using the Atacama Large Millimeter/submillimeter Array.

Satellites and Small Bodies With ALMA: Insights Into Solar System Formation and Evolution
Abstract Our understanding of the formation and evolution of planetary systems has made major advances in the past decade. This progress has been driven in large part by the Atacama Large Millimeter/submillimeter Array (ALMA), which has given us an unprecedented view of solar system bodies themselves, and of the structure and chemistry of forming ...

Safety of selective IL‐23p19 inhibitors for the treatment of psoriasis
Abstract Psoriasis is a chronic disease that requires long‐term treatment. Consequently, understanding the safety and tolerability of any potential treatment over time is critical to effective prescribing. The biologic agents currently available for the treatment of psoriasis target a number of different inflammatory cytokines involved in psoriasis ...

PROTOSTARS AT LOW EXTINCTION IN ORION A [PDF]
ABSTRACT In the list of young stellar objects (YSOs) compiled by Megeath et al. for the Orion A molecular cloud, only 44 out of 1208 sources found projected onto low extinction ( mag) gas are identified as protostars.
