Emisión de gases de efecto invernadero en la economía mexicana y políticas de mitigación, 2020-2030

El Trimestre Económico, 2023
En este trabajo desarrollamos un modelo de insumo-producto medioambiental para la economía mexicana con el fin de explorar qué tanto es posible reducir la emisión de gases de efecto invernadero (GEI) en la economía para 2030.

Gluon- vs. Sea quark-Shadowing [PDF]

, 1998
We calculate the shadowing of sea quarks and gluons and show that the shadowing of gluons is {\it not} simply given by the sea quark shadowing, especially at small $x$.

Cysteine 95 and other residues influence the regulatory effects of Histidine 69 mutations on Human Immunodeficiency Virus Type 1 protease autoprocessing

Retrovirology, 2010
Background Regulated autoprocessing of HIV Gag-Pol precursor is required for the production of mature and fully active protease. We previously reported that H69E mutation in a pseudo wild type protease sequence significantly (>20-fold) impedes protease ...

Vector-to-Pseudoscalar and Meson-to-Baryon Ratios in Hadronic Z Decays at LEP [PDF]

, 2000
Mass dependences of the total production rates per hadronic Z decay of all light-flavour hadrons measured so far at LEP are extrapolated to the zero mass limit (m=0) using phenomenological laws of hadron production related to the spin, isospin ...

Welding on C67 steel grade sheet: Influence of the parameters and post welding heat treatment

AIMS Materials Science, 2023
<abstract> <p>In batch operation, most industries require engineers to maintain low hardness on the welded parts, particularly for low carbon steel. This article focuses on tungsten inert gas (TIG) welding performed on 0.90 mm of a C67 grade sheet by varying different welding parameters such as current, velocity, and temperature.

Demand Shocks, Export Diversification, and Firm Performance During the Great Trade Collapse

Journal of Economics &Management Strategy, EarlyView.
ABSTRACT This paper analyzes the impact of external demand shocks from the 2008 to 2009 Great Trade Collapse on the performance of Chinese exporters and examines how export diversification mitigates these effects. Using Chinese Customs data merged with financial data from all listed Chinese firms, we construct firm‐specific demand shocks based on pre ...

Direct photon interferometry [PDF]

, 2005
We consider recent developments in the theory of the two-photon interferometry in ultrarelativistic heavy ion collisions with emphasis on the difference between photon and hadron interferometry.

“The Excuses We Make”: Defining Eight Corruption Rationalization Categories

Regulation &Governance, EarlyView.
ABSTRACT The rationalization of corruption allows individuals to detach from moral imperatives, enabling them to perceive unethical or unlawful actions as acceptable or justifiable. Closely linked to the concept of moral disengagement, rationalization involves cognitive distortions that frame inhumane or immoral behavior as neither wrong nor ...

Cancer pattern in Bhutan (2014–2022): Findings from population‐based cancer registry—A pathway to monitor cancer control activities

International Journal of Cancer, Volume 158, Issue 11, Page 2829-2840, 1 June 2026.
What's new? The establishment in 2014 of the population‐based cancer registry (PBCR) of Bhutan created new opportunities for understanding national cancer trends, which previously were anticipated from data in neighbouring countries. This study presents the first nine‐year summary of cancer patterns in Bhutan, derived from PBCR data. From 2014 to 2022,

How Large, Decayed, and Moist Must Rotting Logs Be to Act as Thermally Buffered Microhabitats in Temperate Eastern United States Forests?

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study addresses the ecological role of coarse woody debris (CWD) as a thermally buffered microhabitat for saproxylic organisms in temperate eastern US forests. We measured internal and external log temperatures across four seasons in Southern Appalachian forests to test how log diameter, decay stage, and moisture influence thermal buffering.
