War by Legislation: The Constitutionality of Congressional Regulation of Detentions in Armed Conflicts

In this essay, Ford considers provisions of the 2016 National Defense Authorization Act (NDAA) which place restrictions on the disposition of detainees held in Guantánamo Bay. These provisions raise substantial separation of powers issues regarding the ability of Congress to restrict detention operations of the Executive. These restrictions, and similar restrictions found in earlier NDAAs, specifically implicate the Executive\u27s powers in foreign affairs and as Commander in Chief. Ford concludes that, with the exception of a similar provision found in the 2013 NDAA, the restrictions are constitutional

Syria: Can International Law Cope? Workshop Report

The Stockton Center for the Study of International Law at the U.S. Naval War College and the Center for the Rule of Law at the U.S. Military Academy convened a three-day workshop in November 2015. The workshop sought to examine the question posed by its title: Can International Law Cope with the Situation in Syria? It is a question that has ramifications for the viability of international law well beyond the confines of events in Syria. This report surveys the key issues that were raised during the workshop and serves as an introduction to the articles that follow in this forum

Money, Motivation, and Terrorism, Rewards-for-Information Programs

Governments rely on both hard and soft power to neutralize terrorists. The State and Defense Departments offer rewards running to millions of dollars for information to aid in the fight, but these programs receive a surprising lack of scrutiny. Both historical and psychological analysis can improve our framing and execution of such programs

Autonomous Weapons and Weapon Reviews: The UK Second International Weapon Review Forum

This article considers how military lawyers completing weapon reviews might approach their legal duties if confronted with a weapon system that incorporates autonomous technology or artificial intelligence. The article begins by reviewing current and likely near future technological capabilities before considering whether existing international humanitarian law can adequately regulate these technologies. While noting the widespread lack of compliance with Article 36 of Additional Protocol I, the article argues that, properly applied, Article 36 is an effective gatekeeper for keeping unlawful weapon systems from the battlefield. After assessing the feasibility of a preemptive ban on autonomous weapons based on “meaningful human control,” the article argues that “authorized power” provides a better option for regulating future technology within existing international law

Multi-scale Renormalisation Group Improvement of the Effective Potential

Using the renormalisation group and a conjecture concerning the perturbation series for the effective potential, the leading logarithms in the effective potential are exactly summed for $O(N)$ scalar and Yukawa theories.Comment: 19 pages, DIAS STP 94-09.

Quantum inequalities and `quantum interest' as eigenvalue problems

Quantum inequalities (QI's) provide lower bounds on the averaged energy density of a quantum field. We show how the QI's for massless scalar fields in even dimensional Minkowski space may be reformulated in terms of the positivity of a certain self-adjoint operator - a generalised Schroedinger operator with the energy density as the potential - and hence as an eigenvalue problem. We use this idea to verify that the energy density produced by a moving mirror in two dimensions is compatible with the QI's for a large class of mirror trajectories. In addition, we apply this viewpoint to the `quantum interest conjecture' of Ford and Roman, which asserts that the positive part of an energy density always overcompensates for any negative components. For various simple models in two and four dimensions we obtain the best possible bounds on the `quantum interest rate' and on the maximum delay between a negative pulse and a compensating positive pulse. Perhaps surprisingly, we find that - in four dimensions - it is impossible for a positive delta-function pulse of any magnitude to compensate for a negative delta-function pulse, no matter how close together they occur.Comment: 18 pages, RevTeX.

Annotation of gene function in citrus using gene expression information and co-expression networks

Background The genus Citrus encompasses major cultivated plants such as sweet orange, mandarin, lemon and grapefruit, among the world’s most economically important fruit crops. With increasing volumes of transcriptomics data available for these species, Gene Co-expression Network (GCN) analysis is a viable option for predicting gene function at a genome-wide scale. GCN analysis is based on a “guilt-by-association” principle whereby genes encoding proteins involved in similar and/or related biological processes may exhibit similar expression patterns across diverse sets of experimental conditions. While bioinformatics resources such as GCN analysis are widely available for efficient gene function prediction in model plant species including Arabidopsis, soybean and rice, in citrus these tools are not yet developed Results We have constructed a comprehensive GCN for citrus inferred from 297 publicly available Affymetrix Genechip Citrus Genome microarray datasets, providing gene co-expression relationships at a genome-wide scale (33,000 transcripts). The comprehensive citrus GCN consists of a global GCN (condition-independent) and four condition-dependent GCNs that survey the sweet orange species only, all citrus fruit tissues, all citrus leaf tissues, or stress-exposed plants. All of these GCNs are clustered using genome-wide, gene-centric (guide) and graph clustering algorithms for flexibility of gene function prediction. For each putative cluster, gene ontology (GO) enrichment and gene expression specificity analyses were performed to enhance gene function, expression and regulation pattern prediction. The guide-gene approach was used to infer novel roles of genes involved in disease susceptibility and vitamin C metabolism, and graph-clustering approaches were used to investigate isoprenoid/phenylpropanoid metabolism in citrus peel, and citric acid catabolism via the GABA shunt in citrus fruit Conclusions Integration of citrus gene co-expression networks, functional enrichment analysis and gene expression information provide opportunities to infer gene function in citrus. We present a publicly accessible tool, Network Inference for Citrus Co-Expression (NICCE, http://citrus.adelaide.edu.au/nicce/home.aspx), for the gene co-expression analysis in citru

Probability distributions of smeared quantum stress tensors

We obtain in closed form the probability distribution for individual measurements of the stress-energy tensor of two-dimensional conformal field theory in the vacuum state, smeared in time against a Gaussian test function. The result is a shifted Gamma distribution with the shift given by the previously known optimal quantum inequality bound. For small values of the central charge it is overwhelmingly likely that individual measurements of the sampled energy density in the vacuum give negative results. For the case of a single massless scalar field, the probability of finding a negative value is 84%. We also report on computations for four-dimensional massless scalar fields showing that the probability distribution of the smeared square field is also a shifted Gamma distribution, but that the distribution of the energy density is not.Comment: 9 pages, 1 figure.
