Understanding and Regulating C–N Coupling Pathways for Electrocatalytic Urea Synthesis From CO2 and NO3−/NO2−

open access: yesAdvanced Science, EarlyView.
Understanding and regulating C–N coupling is central to electrocatalytic urea synthesis from CO2 and NO3−/NO2−. This review outlines representative coupling pathways, summarizes carbon‐ and nitrogen‐side intermediate regulation strategies, and highlights in situ/operando tools for mechanistic clarification and catalyst design. ABSTRACT Electrocatalytic

Swine Influenza in Sri Lanka

open access: yesEmerging Infectious Diseases, 2013
To study influenza viruses in pigs in Sri Lanka, we examined samples from pigs at slaughterhouses. Influenza (H3N2) and A(H1N1)pdm09 viruses were prevalent during 2004–2005 and 2009–2012, respectively.

Interfacial Tandem Catalysis Over a CuSn(OH)6/Co Heterostructure Enables Efficient Electroreduction of Nitrate to Ammonia

open access: yesAdvanced Science, EarlyView.
Interfacial tandem catalysis is developed for efficient electrochemical reduction of NO3− to NH3 over a CuSn(OH)6/Co heterostructure. CuSn(OH)6 accelerates the rate‐determining NO3−‐to‐*NO2 conversion, whereas Co promotes H2O dissociation to enhance *H supply for the rapid hydrogenation of *NO2 intermediate to NH3.

Valuing volatility spillovers [PDF]

open access: yesGlobal Finance Journal, 2006
Abstract We show that volatility spillovers are large enough to matter to investors. We demonstrate that standard deviations of returns to mean-variance portfolios of European equities fall by 1–1.5% at daily, weekly, and monthly rebalancing horizons when volatility spillovers are included in covariance forecasts.

Collagen‐Binding IL‐15 Immunocytokine Armed Oncolytic Adenovirus Establishes a Self‐Reinforcing Immunostimulatory Milieu to Potentiate Antitumor Immunity

open access: yesAdvanced Science, EarlyView.
Repurposing the dense tumor stroma from a physical barrier into an anchoring scaffold, an engineered oncolytic adenovirus encoding IL15C‐CBD overcomes the immunosuppressive microenvironment in triple‐negative breast cancer. Intratumoral viral replication secretes this collagen‐anchored immunocytokine, forming a localized cytokine depot.

Sectoral growth linkages of agricultural sector: Implications for food security in Pakistan

open access: yesAgricultural Economics (AGRICECON), 2019
Does the growth in non-agricultural sectors spill over to the agricultural sector of an economy? There is limited evidence available on the issue for the developing world, especially for Pakistan which has undergone large structural changes since its ...

Pathogen spillover driven by rapid changes in bat ecology

open access: yes, 2022
During recent decades, pathogens that originated in bats have become an increasing public health concern. A major challenge is to identify how those pathogens spill over into human populations to generate a pandemic threat1.

Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing

open access: yesAdvanced Electronic Materials, EarlyView.
By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...

Do Time-Varying Covariances, Volatility Comovement and Spillover Matter? [PDF]

open access: yes
Financial markets and their respective assets are so intertwined; analyzing any single market in isolation ignores important information. We investigate whether time varying volatility comovement and spillover impact the true variance-covariance matrix ...
