We test three competing explanations of the adult “Hispanic mortality paradox:” data artifact, migration, and cultural or social buffering effects. Based on a series of parametric hazard models estimated on 9 years of mortality follow-up data, our results suggest that the “Hispanic” mortality advantage is a feature found only among foreign-born Mexicans and foreign-born Hispanics other than Cub...

Code-reuse attacks, such as return-oriented programming (ROP), bypass defenses against code injection by repurposing existing executable code toward a malicious end. A common feature of these attacks is the reliance on the knowledge of the layout of the executable code. We propose a fine grained randomization based approach that modifies the layout of executable code and hinders code-reuse atta...

The increase in societal awareness towards environmental issues has accrued the responsibility of goods producers, which at present came to encompass the entire product life cycle. Recently, the efficient design and operation of supply chains with return flows have, in particular, become a major challenge for many companies, given the high number of factors involved and their intricate interact...

Mobile IPv6 is a network-layer mobility protocol for the IPv6 Internet. The protocol includes several security mechanisms, such as the return-routability tests for the care-of addresses. This paper explains the threat model and design principles that motivated the Mobile IPv6 security features. While many of the ideas have become parts of the standard toolkit for designing Internet mobility pro...

Empirical studies have analyzed how investors trade and perform in the financial markets. The studies show that rational trading needs do not explain the excessive manner of trading shown by the investors. Theoretical models offer overconfidence as one of the explanations for irrational trading behavior. Overconfidence is a psychological trait, argued to cause the investors to misinterpret usef...

The increasing shortage of resources has enforced the search for production techniques for biodegradable polymers made of renewable raw materials. An example is polylactide (PLA), an aliphatic polyester, which can be obtained by the metal-catalysed ring-opening polymerisation (ROP) of lactide (Fig. 1). The monomer for PLA production is available from corn or sugar beets by a bacterial fermentat...

Protecting the integrity of code is generally considered as one of the most effective approaches to counteract malicious software (malware). However, the fundamental problem with code-based detection approaches is that they rely on the false assumption that all malware consists of executable instructions. This makes them vulnerable to data-only malware, which, in contrast to traditional malware...

The IIEP has concluded that the ROP is a notable improvement over the previous licensee performance assessment program and should be continued. The reactor oversight process has made progress toward achieving the Agency's four performance goals: 1) maintain safety, 2) increase public confidence, 3) increase regulatory effectiveness and efficiency, and 4) reduce unnecessary regulatory burden. In...

[1] We present an analysis of the seasonally varying ventilation of the stratosphere using one-way flux distributions. Robust transport diagnostics are computed using GEOSCCM subject to fixed present-day climate forcings. From the one-way flux, we determine the mass of the stratosphere that is in transit since entry through the tropical tropopause to its exit back into the troposphere, partitio...

Code-reuse attacks based on return oriented programming are among the most popular exploitation techniques used by attackers today. Few practical defenses are able to stop such attacks on arbitrary binaries without access to source code. A notable exception are the techniques that employ new hardware, such as Intel’s Last Branch Record (LBR) registers, to track all indirect branches and raise a...
