Integrating Spatial Proteogenomics in Cancer Research

Advanced Science, Volume 13, Issue 29, 22 May 2026.
Xx xx. ABSTRACT Background: Spatial proteogenomics marks a paradigm shift in oncology by integrating molecular analysis with spatial information from both spatial proteomics and other data modalities (e.g., spatial transcriptomics), thereby unveiling tumor heterogeneity and dynamic changes in the microenvironment.

The radiative association of PO/PH+ and the photodissociation of PH+

Frontiers in Astronomy and Space Sciences
The potential energy curves (PECs) and transition dipole moments (TDMs) of PH+ and PO are computed with the multireference configuration interaction method, and the cross-sections for the radiative association (RA) of PH+ and PO, which is the most ...

Rate limit for photoassociation of a Bose-Einstein condensate

, 2001
We simulate numerically the photodissociation of molecules into noncondensate atom pairs that accompanies photoassociation of an atomic Bose-Einstein condensate into a molecular condensate. Such rogue photodissociation sets a limit on the achievable rate

Cyclic Peptide Conformational Landscapes Through the Lens of Mass Spectrometry and Orthogonal Spectroscopy

Journal of Mass Spectrometry, Volume 61, Issue 5, May 2026.
ABSTRACT Cyclic peptides occupy a structurally dynamic region of chemical space, where function often arises from ensembles rather than a single dominant fold. Closed backbones, frequent N‐methylation, heteroatoms, unnatural amino acids, and a strong propensity for metal coordination create dense conformational and coordination landscapes that ...

Directional Radiation and Photodissociation Regions in Molecular Hydrogen Clouds

, 2008
Some astrophysical observations of molecular hydrogen point to a broadening of the velocity distribution for molecules at excited rotational levels. This effect is observed in both Galactic and high redshift clouds. Analysis of H_2, HD, and CI absorption

Soft X‐Ray Emission From Saturn's Magnetosheath II: Solar Wind Driving

Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.
Abstract Saturn's magnetosphere is dominated by Enceladus‐sourced neutrals, which spread throughout the system into the magnetosheath. The neutrals can charge exchange with highly charged solar wind ions, causing soft X‐ray emission (<2 ${< } 2$ keV) upon de‐excitation of the ion.

Near-UV photolysis cross sections of CH₃OOH and HOCH₂OOH determined via action spectroscopy [PDF]

Atmospheric Chemistry and Physics, 2007
Knowledge of molecular photolysis cross sections is important for determining atmospheric lifetimes and fates of many species. A method and laser apparatus for measurement of these cross sections in the near-ultraviolet (UV) region is described.

CALCULATION OF CHEMICAL EQUILIBRIUM IN THE INTERSTELLAR CLOUD

Odessa Astronomical Publications, 2017
In order to calculate the molecular concentrations in the interstellar cloud and to obtain heir spatial distribution we have made a computational code to solve the set of equations for chemical equilibrium and equations of charge and atom balance.

Radiation Hydrodynamics Simulations of Photoevaporation of Protoplanetary Disks by Ultra Violet Radiation: Metallicity Dependence

, 2018
Protoplanetary disks are thought to have lifetimes of several million years in the solar neighborhood, but recent observations suggest that the disk lifetimes are shorter in a low metallicity environment.

Transport of Water in a Transient, Impact‐Generated Atmosphere on Mercury

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mercury's polar cold traps host water ice deposits that are likely populated with impact‐delivered water via Mercury's exosphere. However, Mercury's near‐sun location experiences an extremely high photodestruction rate that rapidly destroys water with a timescale of only ∼3.5 hr.
