A multi-labelled tree (or MUL-tree) is a rooted tree leaf-labelled by a set of labels, where each label may appear more than once in the tree. We consider the MUL-tree Set Pruning for Consistency problem (MULSETPC), which takes as input a set of MUL-trees and asks whether there exists a perfect pruning of each MUL-tree that results in a consistent set of single-labelled trees. MULSETPC was proven to be NP-complete by Gascon et al. when the MUL-trees are binary, each leaf label is used at most three times, and the number of MUL-trees is unbounded. To determine the computational complexity of the problem when the number of MUL-trees is constant was left as an open problem. Here, we resolve this question by proving a much stronger result, namely that MULSETPC is NP-complete even when there are only two MUL-trees, every leaf label is used at most twice, and every MUL-tree is either binary or has constant height. Furthermore, we introduce an extension of MULSETPC that we call MULSETPComp, which replaces the notion of consistency with compatibility, and prove that MULSETPComp is NP-complete even when there are only two MUL-trees, every leaf label is used at most thrice, and every MUL-tree has constant height. Finally, we present a polynomial-time algorithm for instances of MULSETPC with a constant number of binary MUL-trees, in the special case where every leaf label occurs exactly once in at least one MUL-tree.

The aerosol-driven radiative effects on marine low-level cloud represent a large uncertainty in climate simulations, in particular over the Southern Ocean, which is also an important region for sea spray aerosol production. Observations of sea spray aerosol organic enrichment and the resulting impact on water uptake over the remote Southern Hemisphere are scarce, and therefore the region is underrepresented in existing parameterisations. The Surface Ocean Aerosol Production (SOAP) voyage was a 23 d voyage which sampled three phytoplankton blooms in the highly productive water of the Chatham Rise, east of New Zealand. In this study we examined the enrichment of organics to nascent sea spray aerosol and the modifications to sea spray aerosol water uptake using in situ chamber measurements of seawater samples taken during the SOAP voyage. Primary marine organics contributed up to 23% of the sea spray mass for particles with diameter less than approximately 1 m and up to 79% of the particle volume for 50 nm diameter sea spray. The composition of the submicron organic fraction was consistent throughout the voyage and was largely composed of a polysaccharide-like component, characterised by very low alkane-to-hydroxylconcentration ratios of approximately 0.1 0.2. The enrichment of organics was compared to the output from the chlorophyll-a-based sea spray aerosol parameterisation suggested by Gantt et al. (2011) and the OCEANFILMS (Organic Compounds from Ecosystems to Aerosols: Natural Films and Interfaces via Langmuir Molecular Surfactants) models. OCEANFILMS improved on the representation of the organic fraction predicted using chlorophyll a, in particular when the co-adsorption of polysaccharides was included; however, the model still under-predicted the proportion of polysaccharides by an average of 33 %. Nascent 50 nm diameter sea spray aerosol hygroscopic growth factors measured at 90% relative humidity averaged 1:930:08 and did not decrease with increasing sea sp

Sex differences in self-reported homonegativity is prevalent in past research, yet unexplained. We examined possible factors associated with sex differences in overall homonegativity. Heterosexuals self-reported on scales including variables of differential exposure to homosexuals, disgust sensitivity, and reporting biases. Males consistently expressed more negative attitudes toward homosexuals, especially gay men. Many variables were significantly correlated with overall homonegativity and revealed significant sex differences, however, unconvincingly. Self-report measures may lack validity, not always capturing peoples true attitudes. Utilizing a new paradigm of implicit cognitive systems may be more worthwhile in explaining social psychological representations of the abstract cognitive construct of prejudice/stereotyping.

Ex-Mayor of Batavia, New York, Harvey J. Burkhart advises William Loeb to immediately formulate a plan to elect Roosevelt supporting delegates to the Republican National Convention. Burkhart warns that the same forces keeping Archie Dovell Sanders in office as the Collector of Internal Revenue are "interfering in post office matters" with Assemblyman James Wadsworth supporting them. Burkhart will help President Roosevelt in any way possible and offers to meet with Loeb to speak with him about the matter if he feels he cannot write about the issue.

The attractive possibility of minimizing ordering, handling and warehousing problems by employing uniform longitudinal scantlings and constant plating thicknesses throughout the midship section led to the decision to carry out an investigation of such a design methodology. The design technique proved to be feasible, but less economical that conventional techniques of midship section design. A computer tool for the systematic variation of longitudinal intervals has been developed and is now ready to be applied to midship section design with varying structural materials and different plating thicknesses and longitudinal scantlings.

The X-ray diffraction method of stress measurement is the only known means of determining absolute stress magnitudes without measurements in the unstressed condition. It is the objective of this thesis to investigate the feasibility of using this method in analysis of naval structures both aboard ship and on models.

This thesis describes the programming of amidship structural design procedures for the IBM-704 computer. Two problems, the selection of scantlings and plating for the amidships portion of a ship's hull and the design of a transverse web frame are programmed for a digital computer. A detailed explanation of the programs and a brief discussion of the methods of approach for adapting these design procedures to a digital computer are included. Using rather simple engineering criteria, these programs essentially carry out the design procedures for the amidship's structure. The inputs are those forces moments, dimensions and material characteristics which are either known or can be readily determined by the user. The information resulting from these programs is given in a convenient form. The programs have been written in such a manner that they may be easily followed and altered. It is strongly emphasized that these programs are written with a factor of safety of 1.0 on the yield strength of the material. By suitably selecting the input information any reasonable factor of safety may be obtained.
