Reductive Supramolecular In Situ Construction of Nano‐Platinum Effectively Couples Cathodic Hydrogen Evolution and Anodic Alcohol Oxidation

Advanced Science, EarlyView.
The supramolecular framework reductant is developed to realize the in situ construction of highly dispersed ultrafine nano‐Pt. The nano‐Pt supported on the BCN carrier realizes multi‐scenario electrocatalytic water hydrogen production, and establish a high‐performance cathode hydrogen evolution‐anode methanol oxidation coupling system, presenting a low‐

C1q+ Macrophage–Tumor Cell Interaction Promoted Tumorigenesis via GPR17/PI3K/AKT Pathway Induced DNA Hypermethylation in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
In the TME of NPC, C1q secreted by C1q+ TAMs interacted with GPR17 to activate PI3K/AKT signaling through strengthening GPR17 coupling PI3K and increasing calcium levels in tumor cells. The activated PI3K/AKT signaling further induces DNA hypermethylation to promote the malignancy and stemness of tumor cells.

A Giant Bipolar Shell around the WO star in the Galaxy IC 1613: Structure and Kinematics [PDF]

Astronomy Letters, 2000, v.26, No 3, pp. 153-161, 2000
Observations of the nebula associated with the WO star in the galaxy IC 1613 are presented. The observations were carried out with a scanning Interferometer Fabry-Perot in H_alpha at the 6m Special Astrophysical Observatory telescope; narrow-band H_alpha and [OIII] images were obtained with the 4-m KPNO telescope.

The future of dispute resolution in international trade

Applied Economic Perspectives and Policy, EarlyView.
Abstract Given ongoing dysfunction of the World Trade Organization's Appellate Body, the focus of this article is on the future of trade dispute resolution, with evaluation of two questions: (i) What is the current status of WTO dispute resolution as compared to that conducted through existing preferential trade agreements (PTAs)? and (ii) What are the

Millennium-length precipitation reconstruction over south-eastern Asia: a pseudo-proxy approach [PDF]

Earth System Dynamics, 2019
Quantifying precipitation variability beyond the instrumental period is essential for putting current and future fluctuations into long-term perspective and providing a test bed for evaluating climate simulations.

Dense Iron Ejecta and Core-collapse Supernova Explosion in the Young Supernova Remnant G11.2-0.3 [PDF]

, 2009
We present the results of near-infrared spectroscopic observations of dense ($\simgt$ 10$^3$ cm$^{-3}$) iron ejecta in the young core-collapse supernova remnant G11.2-0.3. Five ejecta knots projected to be close to its center show a large dispersion in their Doppler shifts: two knots in the east are blueshifted by more than 1,000 \kms, while three ...

Staging an Experience of Cultural Heritage Preservation: Consumers' Willingness to Pay for Heirloom Rice in the Philippines

Agribusiness, EarlyView.
ABSTRACT The Cordillera Administrative Region in the Philippines is home to terraced rice embedded in centuries of cultural heritage. However, weak market incentives threaten sustained production, jeopardizing indigenous communities' cultural heritage and the in situ biodiversity of rice genetic resources.

India–United States Agricultural Trade Under the America‐First Agenda

Agribusiness, EarlyView.
ABSTRACT This article examines India–United States agricultural trade under the America‐First agenda, highlighting trade patterns, tariff structures, and potential impacts of United States trade policies. Total agricultural trade remains modest at $7 billion annually, with India imposing higher tariffs (average 39%) than the United States (5%).
