Strength and Breaking Mechanism of Multiwalled Carbon Nanotubes Under Tensile Load

The tensile strengths of individual multiwalled carbon nanotubes (MWCNTs) were measured with a “nanostressing stage” located within a scanning electron microscope. The tensile-loading experiment was prepared and observed entirely within the microscope...

How Much Should We Trust Differences-in-Differences Estimates?

Most papers that employ Differences-in-Differences estimation (DD) use many years of data and focus on serially correlated outcomes but ignore that the resulting standard errors are inconsistent. To illustrate the severity of this issue, we randomly generate...

A maximum entropy approach to natural language processing

The concept of maximum entropy can be traced back along multiple threads to Biblical times. Only recently, however, have computers become powerful enough to permit the widescale application of this concept to real world problems in statistical estimation...

Event-Related EEG/MEG Synchronization and Desynchronization: Basic Principles

An internally or externally paced event results not only in the generation of an event-related potential (ERP) but also in a change in the ongoing EEG/MEG in form of an event-related desynchronization (ERD) or event-related synchronization (ERS). The...

Cobalt-catalysed growth of carbon nanotubes with single-atomic-layer walls

CARBON exhibits a unique ability to form a wide range of structures. In an inert atmosphere it condenses to form hollow, spheroidal fullerenes. Carbon deposited on the hot tip of the cathode of the arc-discharge apparatus used for bulk fullerene synthesis...

Word association norms, mutual information, and lexicography

The term word association is used in a very particular sense in the psycholinguistic literature. (Generally speaking, subjects respond quicker than normal to the word nurse if it follows a highly associated word such as doctor. ) We will extend the term...

Prostaglandins and Leukotrienes: Advances in Eicosanoid Biology

Identification of Causal Effects Using Instrumental Variables

We outline a framework for causal inference in settings where assignment to a binary treatment is ignorable, but compliance with the assignment is not perfect so that the receipt of treatment is nonignorable. To address the problems associated with comparing...

A cellular automaton model for freeway traffic

We introduce a stochastic discrete automaton model to simulate freeway traffic. Monte-Carlo simulations of the model show a transition from laminar traffic flow to start-stop- waves with increasing vehicle density, as is observed in real freeway traffic....

A Critical Review of Construct Indicators and Measurement Model Misspecification in Marketing and Consumer Research

Anomalies: The Endowment Effect, Loss Aversion, and Status Quo Bias

Economics can be distinguished from other social sciences by the belief that most (all?) behavior can be explained by assuming that agents have stable, well-defined preferences and make rational choices consistent with those preferences in markets that...

Does Trust Matter? Exploring the Effectsof Interorganizational and Interpersonaltrust on Performance

A conceptual challenge in exploring the role of trust in interorganizational exchange is translating an inherently individual-level concept-trust-to the organizational-level outcome of performance. We define interpersonal and interorganizational trust...

Studying Information Technology in Organizations: Research Approaches and Assumptions

We examined 155 information systems research articles published from 1983 to 1988 and found that although this research is not rooted in a single overarching theoretical perspective, it does exhibit a single set of philosophical assumptions regarding...

The Sybil Attack

Large-scale peer-to-peer systems face security threats from faulty or hostile remote computing elements. To resist these threats, many such systems employ redundancy. However, if a single faulty entity can present multiple identities, it can control a...
