Selection mechanisms affect volatility in evolving markets

open access: yes, 2019
Financial asset markets are sociotechnical systems whose constituent agents are subject to evolutionary pressure as unprofitable agents exit the marketplace and more profitable agents continue to trade assets.

Reevaluating the Activity of ZIF‐8 Based FeNCs for Electrochemical Ammonia Production

open access: yesAdvanced Functional Materials, EarlyView.
Though receiving much attention, the field of electrochemical nitrogen reduction reaction (eNRR) to ammonia is marked by doubts about whether this reaction is possible in aqueous media. This work sheds light on this question for iron single‐atom on N‐doped carbon (FeNC) catalysts—a class of well‐known catalysts that is also worth testing for the sister

Are markets adaptive? Evidence of predictability and market efficiency of lodging/resort REITs

open access: yesInternational Journal of Strategic Property Management, 2020
We investigate the degree of return predictability of lodging/resort real estate investment trusts (REITs) from January 1994 to May 2016. We test the Martingale hypothesis by using linear (automatic portmanteau and automatic variance ratio with rolling ...

Allocation Problems in Ride-Sharing Platforms: Online Matching with Offline Reusable Resources

open access: yes, 2017
Bipartite matching markets pair agents on one side of a market with agents, items, or contracts on the opposing side. Prior work addresses online bipartite matching markets, where agents arrive over time and are dynamically matched to a known set of ...

A Bespoke Programmable Interpenetrating Elastomer Network Composite Laryngeal Stent for Expedited Paediatric Laryngotracheal Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
A programmable interpenetrating double‐network architecture, created via 3D‐TIPS printing and resin infusion, synergistically combines thermoplastic and thermosetting elastomers to balance structural rigidity and surface softness—crucial for paediatric laryngeal stents.

Analysis and forecasting of pet food markets using extrapolation methods

open access: yesВісник Харківського національного університету імені В.Н. Каразіна: Серія Економіка
One of the manifestations of the socialization of the economy is a change in the behavior of consumers, which leads to shifts in the structure of markets, the nomenclature of goods presented on them, and fluctuations in the ratio between supply and ...

Lessons from the evolution of foreign exchange trading strategies [PDF]

open access: yes
The adaptive markets hypothesis posits that trading strategies evolve as traders adapt their behavior to changing circumstances. This paper studies the evolution of trading strategies for a hypothetical trader who chooses portfolios from foreign exchange

Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

open access: yesAdvanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

High‐Yield Synthesis of Fe‐NC Electrocatalysts Using Mg2+ Templating and Schiff‐Base Porous Organic Polymers

open access: yesAdvanced Functional Materials, EarlyView.
Fe─NC porous oxygen reduction electrocatalysts are prepared employing a 2,4,6‐Triaminopyrimidine‐based porous organic polymer, a Mg2+ Lewis acid, and a low‐temperature cation exchange protocol. Using the polymer precursor achieves high pyrolysis yields and results in atomically dispersed FeNx sites. The resulting catalysts feature hierarchical porosity
