The Efficient Market Hypothesis and Insider Trading on the Stock Market [PDF]
Journal of Political Economy, 1990 We study the behavior of a large trader with private information about the mean of an asset with a risky return. We argue that if the variability of the return is not too great, typically the trader will find it desirable to ensure that the market price does not reveal his information, that is, that a "pooling" equilibrium arises.

Stabilized Bi(III) Sites Direct *NH2OH Pathway for Efficient Cyclohexanone Oxime Electrosynthesis
Advanced Materials, EarlyView.The electron‐buffering effect stabilizes Bi3+ sites under electroreductive conditions, preserving a favorable interfacial water configuration that sustains the selective *NH2OH pathway and enables efficient cyclohexanone oxime electrosynthesis. ABSTRACT Coupling electrocatalytic nitrite reduction reaction (NO2−RR) with cyclohexanone conversion enables ...

High‐Performance Bio‐Glue From the Berries of a Parasitic Plant
Advanced Materials, EarlyView.We report a fully bio‐based adhesive derived primarily from a (poly)saccharide extract obtained from the berries of the hemi‐parasitic plant mistletoe (Viscum album), supplemented with tannic and malic acid without any further chemical functionalization.

Efficient market hypothesis in European stock markets [PDF]
The European Journal of Finance, 2010 This paper reports the results of tests on the weak-form market efficiency applied to stock market indexes of UK, France, Germany, Spain, Greece and Portugal, from January 1993 to December 2007. We use a runs test, and joint variance ratio tests, which are performed using daily and weekly data for the period 1993–2007 and for a subset, 2003–2007. Daily

From Payload‐First Toward Dual‐Mechanism Antibody–Drug Conjugates
Advanced Materials, EarlyView.Conjugation converts potent antibodies into underexposed carriers. This perspective defines the antibody exposure deficit and maps a mechanism‐first design space from payload‐first to antibody‐first ADC architectures, integrating DAR, linker chemistry, and Fc engineering to guide rational design of constructs that balance targeted cytotoxicity with ...

Efficient market hypothesis: is the Croatian stock market as (in)efficient as the U.S. market [PDF]
Financial Theory and Practice, 2011 Traditional statistical tests of serial independence of stock price changes often show that stock markets are ineffi cient. Our analysis on daily and monthly data confirms this finding for the Croatian and U.S.

Consensus Formation and Change are Enhanced by Neutrality
Advanced Science, EarlyView.Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.
