In recent years, there has been new and growing interest in ergativity among researchers working within the generative framework. This two-part lecture describes the basic facts about so-called ergative languages and then examines the existing approaches to ergative case assignment (Lecture 1) and syntactic ergativity (Lecture 2). Our main objective is to explore whether ergativity can be shown...

The ability to create architected materials that possess both high stiffness and toughness remains an elusive goal, since these properties are often mutually exclusive. Natural materials, such as bone, overcome such limitations by combining different toughening mechanisms across multiple length scales. Here, a new method for creating architected lattices composed of core-shell struts that are b...

3D printing is expected to revolutionize health care through uses in tissue and organ fabrication; creation of customized prosthetics, implants, and anatomical models; and pharmaceutical research regarding drug dosage forms, delivery, and discovery.

Introduction: Burkitt lymphoma (BL) is rare, but an aggressive malignancy. Central nervous system Burkitt lymphoma (CNSBL) is very rare. CNS Burkitt’s lymphoma is treated with high-dose chemotherapy and radiation. Radiotherapy in children younger than three years old may cause major CNS damage. Case report: A three-year-old boy presented with painful proptosis of the left eye. He under...

The patent law also encourages public disclosure of inventions, at least in part because secret innovations are less likely to promote progress than those disclosed to the public. In this regard, U.S. patent law attenuates the legal effect of innovations that are not properly disclosed to the public. One such provision is codified at 35 U.S.C. § 102(g), which is an important, albeit seldom used...

A projected hybrid orbital (PHO) method was described to model the covalent boundary in a hybrid quantum mechanical and molecular mechanical (QM/MM) system. The PHO approach can be used in ab initio wave function theory and in density functional theory with any basis set without introducing system-dependent parameters. In this method, a secondary basis set on the boundary atom is introduced to ...
