A comparative study of multiwavelength blazar variability on decades to minutes timescales

Multiwavelength blazar variability is produced by noise-like processes with the power-law form of power spectral density (PSD). We present the results of our detailed investigation of multiwavelength ( γ -ray and optical) light curves covering decades to minutes timescales, of two BL Lac objects namely, PKS 0735+178 and OJ 287. The PSDs are derived using discrete Fourier transform (DFT) method. Our systematic approach reveals that OJ 287 is, on average, more variable than PKS 0735+178 at both optical and γ -ray energies on the corresponding time scales. On timescales shorter than ∼10 days, due to continuous and dense monitoring by the Kepler satellite, a steepening of power spectrum is observed for OJ 287. This indicates the necessity of an intermittent process generating variability on intra-night timescales for OJ 287

The Role of Technological Complexity and Absorptive Capacity in Internalization Decision

Technology transfer costs have a profound influence on the firm’s entry mode into a production sharing relationship. To explore this nexus, we associate technological complexity of the off-shored input with the organizational mode of international production sharing by extending the Antràs (2005) model. We modify the Antràs model by proposing that the low-tech input, as qualified within the model, cannot be produced in the low wage south without costly technology transfer. The cost of technology transfer in turn depends on three factors, which are the technological complexity of this input, the absorptive capacity of the host country and the wages of the host country. Our model refines the results obtained in Antràs (2005). We find that 1. For high-tech goods, intra-firm transfer is preferred vis-à-vis outsourcing only for intermediate range of technological complexity of the off-shored input, 2. On the other hand, for low-tech goods, where the likelihood of outsourcing is higher in Antràs, intra-firm offshore contract is still possible for low range of technological complexity. Our model has policy suggestions for host countries which aspire to maximize their benefits from the exploding global production phenomenon. As the wage gap between the source and the host country falls, cost considerations for offshoring disappear. New sources of comparative advantage should therefore be created in the host country by subsidizing technology investment and higher education to build higher absorptive capacity.Outsourcing, Foreign Direct Investment, Technology Transfer, Absorptive Capacity.

Who’s Afraid of the Federal Circuit?

In this brief Essay, Professor Rai responds to Professor Jonathan Masur\u27s Yale Law Journal article Patent Inflation. Professor Masur\u27s argument rests on the assumption that U.S. Patent and Trademark Office ( PTO ) behavior is determined almost entirely by a desire to avoid reversal by the Federal Circuit. Although the PTO is certainly a weak agency over which the Federal Circuit has considerable power, Masur overestimates the extent to which high-level PTO administrators are concerned about Federal Circuit reversals and underestimates institutional influences that are likely to operate in a deflationary direction. The PTO is influenced not only by the Federal Circuit but also by executive branch actors, industry players, and workload concerns that can push in a deflationary direction

Specialized Trial Courts: Concentrating Expertise on Fact

In the absence of a specialized patent trial court with expertise in fact-finding, the Court of Appeals for the Federal Circuit often reviews de novo the many factual questions that pervade patent law. De novo review of fact by an appellate court is problematic. In the area of patent law, as in other areas of law, there are sound institutional justifications for the conventional division of labor that gives trial courts primary responsibility for questions of law. This Article identifies the problems created by de novo appellate review of fact and argues for the creation of a specialized trial court to which the Federal Circuit would feel compelled to defer on questions of fact. It also discusses how such a court would be designed, focusing on the manner in which trial court judges could use the court-appointed advisors to evaluate competing factual claims

Unstandard Standardization: The Case of Biology

How applicable are the approaches adopted by information and communication technology standards-setting organizations to biological standards? Most engineering-based industries construct products from standard, well understood components. By contrast, despite the early attachment of the moniker “genetic engineering” to biotechnology, standardization in the biological sciences has been relatively rare

Biomedical Patents at the Supreme Court: A Path Forward

Although most would argue that software patents pose a bigger challenge, the U.S. Supreme Court has recently focused on biomedical patents. Two of the Court\u27s recent decisions scaling back such patents, Mayo v. Prometheus and AMP v. Myriad, have provoked justifiable anxiety for those concerned about biomedical innovation, particularly in the area of personalized medicine. While acknowledging significant limitations in the Court\u27s reasoning in both cases, this Essay sketches a reading that is consistent with the results and innovation-friendly
