Investigating spillovers (potential costs and benefits to a firm that extend beyond an individual transaction), I integrate transaction cost theory and the knowledge-based view of the firm in an effort to better understand the efficient governance of knowledge. Contracts with detailed task descriptions were associated with transactions with the potential to generate new and reusable knowledge. ...

Hydropneumothorax is an uncommon but potentially fatal complication for a patient undergoing positive pressure ventilation. The case of a 23-year-old woman with severe asthma requiring lung lavage is described. Twenty minutes after an uneventful left lung lavage, the patient experienced increased peak airway pressure, decreased oxygen saturation and hypercarbia, despite ventilation with 90 per ...

136 biotech and life sciences worldwide as part of a larger project to map human technological development (Fig 1). “Maps can help answer or at least address a number of key questions,” said Hoffman. “Where around the world is biotech really happening or beginning to happen? How important is economic geography now that the life sciences are spilling out of university, governmental and industria...

We present a simple algorithm for register allocation which is competitive with the iterated register coalescing algorithm of George and Appel. We base our algorithm on the observation that 95% of the methods in the Java 1.5 library have chordal interference graphs when compiled with the JoeQ compiler. A greedy algorithm can optimally color a chordal graph in time linear in the number of edges,...

Two of the most important phases of code generation for instruction level parallel processors are register allocation and instruction scheduling. Applying one phase before the other has in both cases its drawbacks. In this paper we present a new method which integrates register allocation and scheduling, called Registers on Demand. We discuss register selection, spilling and the insertion of st...

A Baker’s (popliteal) cyst is a distention of the gastrocnemius–semimembranous bursa of the knee, which communicates with the posterior portion of the joint capsule. It usually appears in the popliteal fossa as a painless swelling. In adults it is nearly always secondary to pathological changes in the knee joint that cause an effusion. Occasionally the cyst becomes so large that it ruptures, sp...

Stable ruthenium nanoparticles were prepared by passivation of the metal cores (diameter 2.7–3.2 nm by transmission electron microscopy) with ruthenium–carbon covalent bonds. Electrochemical study showed that the electronic conductivity of the particle films exhibited metal-like temperature dependence, and it decayed exponentially with the length of the alkyl spacer of the aliphatic protecting ...

Recent work has shown that the subtasks of register allocation (spilling, register assignment, and coalescing) can be completely separated. This work presents an algorithm for the coalescing subproblem that relies on this separation. The algorithm uses 0/1 Linear Programming (ILP), a general-purpose optimization technique, to derive optimal solutions. We provide the first optimal solutions for ...

In this paper, we numerically study an enhancement of breakdown voltage in AlGaN/GaN high-electron-mobility transistors (HEMTs) by using the AlGaN/GaN/AlGaN quantum-well (QW) electron-blocking layer (EBL) structure. This concept is based on the superior confinement of two-dimensional electron gases (2-DEGs) provided by the QW EBL, resulting in a significant improvement of breakdown voltage and ...

Abstract The article presents the results of laboratory-field tests a working body that creates an artificial pipe for irrigation cotton with row spacing 60 cm from under soil. As evaluation criteria, water flow distance and moisture dispersion were taken inside formed without spilling onto field surface. When using this body, it was found dense walls soil low energy consumption, observed long ...
