Undersea Lawfare: Can the U.S. Navy Fall Victim to This Asymmetric Warfare Threat?

As the world’s only superpower, the United States of America finds itself challenged by adversaries who know they cannot confront it directly, toe to toe, on traditional battlefields, or on or under the world’s oceans. In their attempts to follow Sun Tzu’s instruction to “subdue the enemy without fighting,” potential adversaries of the United States continuously assess and probe American strengths and weaknesses to identify vulnerabilities for military, political, and industrial exploitation. It is not fully appreciated, assessed, or addressed by American policy makers and warfighters how vulnerable the U.S. military is to the threat of “lawfare,” both international and domestic environmental

Phosphorus and swine feeding

This article focuses on developing a phosphorus (P) strategy for swine feeding operations and continues a series that provides producers with information on P management and environmental issues relating to P management

Mapping and explaining the productivity of Pinus radiata in New Zealand

Mapping Pinus radiata productivity for New Zealand not only provides useful information for forest owners, industry stakeholders and policy managers, but also enables current and future plantations to be visualised, quantified, and planned. Using an extensive set of permanent sample plots, split into fitting (n = 1,146) and validation (n = 618) datasets, models of P. radiata 300 Index (an index of volume mean annual increment) and Site Index (an index of height growth) were developed using a regression kriging technique. Spatial predictions were accurate and accounted for 61% and 70% of the variance for 300 Index and Site Index, respectively. Productivity predicted from these surfaces for the entire plantation estate averaged 27.4 m³ ha⁻¹ yr⁻¹ for the 300 Index and 30.4 m for Site Index. Surfaces showed wide regional variation in this productivity, which was attributable mainly to variation in air temperature and root-zone water storage from site to site

Report to the California Public Utilities Commission Regarding Ex Parte Communications and Related Practices

Part I contains the analysis of existing law. We review the statutes and regulations governing ex parte communications before the CPUC, examine corresponding laws of other jurisdictions, and compare the CPUC statutes and regulations with those of the other jurisdictions. In Part II we examine actual ex parte practices before the CPUC. Based on data obtained from notices filed on the Commission’s website by parties to rate-setting cases, we provide a quantitative characterization of the extent and nature of noticed ex parte communications over the past roughly 22 years. We then place ex parte communications within the context of the CPUC’s proceedings. Part III provides the results of an interview process we undertook to hear the experiences and opinions of people with a stake or an interest in CPUC decision-making, including representatives of regulated utilities, intervenor groups who generally (but not always) appear in CPUC rate-setting cases in opposition to the positions of utilities, companies and industry groups who generally oppose specific utilities’ positions, legislators and legislative staff, public critics of CPUC ex parte practices, CPUC staff (administrative law judges (ALJs), attorneys, and technical staff), and the CPUC Commissioners and their staffs. Then, in Part IV, we present our analysis of this information and our recommendations for changes to statutes, CPUC rules, and Commission practices

Capacity limitations of visual memory in two-interval comparison of Gabor arrays

The capacity of short-term visual memory (VSTM) was assessed in a two-interval spatial frequency (SF) discrimination task. The cued Gabor target in a multi-element array either increased or decreased in SF across a 2s interstimulus interval (ISI). Distracters as well as target were made to change across ISI so that memory of the individual SF of Gabor elements was required to solve the discrimination. The dynamics of the information loss from visual memory were analysed by manipulating the timing of spatial cues and masks. Cueing the target position before the first display gave thresholds comparable with those for a single Gabor patch. Cues placed after the first display gave higher thresholds indicating some loss of information. Within the ISI there was little increase in threshold or set size effect with cue delay. However there was a sharp rise in thresholds for cue positions after the second display. Gabor masks placed before a mid-ISI cue were more effective than noise masks or Gabor masks placed after the cue. With a cue placed late in the ISI, preceded by a Gabor mask, the masking effect decreased with increasing delay of the mask after the first display. This suggests a selective, dynamic but increasingly durable representation of the initial stimulus is built up in memory, and there is a graded form of “overwriting” of this representation by new stimuli

Cooling and the SU(2) Instanton Vaccuum

We present results of an investigation into the nature of instantons in 4-dimensional pure gauge lattice $SU(2)$\ obtained from configurations which have been cooled using an under-relaxed cooling algorithm. We discuss ways of calibrating the cooling and the effects of different degrees of cooling, and compare our data for the shapes, sizes and locations of instantons with continuum results. In this paper we extend the ideas and techniques developed by us for use in $O(3)$, and compare the results with those obtained by other groups.Comment: 22 pages, LaTeX, uuencoded compressed tarfile of figures sent separately.
