Emergence and Adult Biology of \u3ci\u3eAgrilus Difficilis\u3c/i\u3e (Coleoptera: Buprestidae), a Pest of Honeylocust, \u3ci\u3eGleditsia Triacanthos\u3c/i\u3e

Emergence and adult biology of Agrilus difficilis were examined in relation to its host Gleditsia triacanthos. began as early as 5 June in 1982 and completed as late as 22 July in 1983. Females lived significantly longer, 48 days, than males, 29 days. Average fecundity was one egg per day during a 36-day oviposition period

The motif problem

Fix a choice and ordering of four pairwise non-adjacent vertices of a parallelepiped, and call a motif a sequence of four points in R^3 that coincide with these vertices for some, possibly degenerate, parallelepiped whose edges are parallel to the axes. We show that a set of r points can contain at most r^2 motifs. Generalizing the notion of motif to a sequence of L points in R^p, we show that the maximum number of motifs that can occur in a point set of a given size is related to a linear programming problem arising from hypergraph theory, and discuss some related questions.Comment: 17 pages, 1 figur

The Economics of Selling Crop Residue Biomass for Cellulosic Ethanol Production at the Farm Level

A partial budget decision making framework has been developed to assist crop producers in analyzing the profitability of selling cellulosic biomass from their fields for ethanol production. A multidisciplinary approach is taken in assessing the agronomic and economic factors relevant to biomass contract sales decisions – with direct application made to western Great Plains cropping systems and enterprises. Within this framework the benefits of increased revenue from cellulosic biomass contract sales and potential government assistance payments are considered against possible decreased revenue from diminished crop yields resulting from less crop residue cover and subsequent soil moisture evaporation. Increased biomass harvesting and handling are also considered, as is the cost of replacing crop nutrients removed as part of biomass harvest operations. Examples of the profitability of cellulosic biomass contract sales in center pivot irrigated corn and non-irrigated wheat enterprises are shown.Resource /Energy Economics and Policy,

Towards Flight Trials for an Autonomous UAV Emergency Landing using Machine Vision

This paper presents the evolution and status of a number of research programs focussed on developing an automated fixed wing UAV landing system. Results obtained in each of the three main areas of research as vision-based site identification, path and trajectory planning and multi-criteria decision making are presented. The results obtained provide a baseline for further refinements and constitute the starting point for the implementation of a prototype system ready for flight testing

Translating Between Programming Languages Using A Canonical Representation And Attribute Grammar Inversion

Automatic translation between programming languages is an important tool for increasing program reusability. Often the need arises to transport a large software system from one source language environment to another. Performing such a translation by hand is a large undertaking, costly in manpower and very error-prone. For this reason, several researchers have built automated tools to aid them in particular such projects [3, 1]. In this paper we present a new methodology for building source-to-source translators. This methodology involves designing a canonical form to represent programs of all source languages involved, and using attribute grammars (AGs) and automatic AG-inversion to build bidirectional translators between the various source languages and the canonical form. To test the feasibility of these ideas, we have created a system to translate between the C and Pascal programming languages

USING MIXED-INTEGER PROGRAMMING TO DETERMINE THE POTENTIAL FOR FLOUR-MILLING INDUSTRY EXPANSION

As in most predominantly agricultural states, agricultural producers in Oklahoma have expressed an interest in value-added processing opportunities. While Oklahoma produces mostly hard red winter wheat, most Oklahoma bakers require predominantly soft wheat flour for their products, almost all of which is purchased from out-of-state suppliers. An economic engineering-based, mixed-integer programming model was used to determine the optimal number, size, and location of additional flour mills in Oklahoma to capture this excess flour demand. The results suggest that additional mills are potentially justified and that the potential for additional milling will increase if Oklahoma soft wheat production increases.Agribusiness,

FEASIBILITY OF AN OKLAHOMA FRESH GREENS AND COWPEAS PACKING COOPERATIVE

Oklahoma's green producers are not benefiting from a growing fresh market. In order to seize the opportunities offered by the growing fresh market for leafy greens, investment in packing facilities have been evaluated. To make use of these facilities during summer months, the addition of a cowpea shelling enterprise is considered. A business plan for a new generation cooperative is estimated using an updated version of "The Packing Simulation Model" (PACKSIM) The business associates PACKSIM with @RISK®, to incorporate risks in the financial analysis.Agribusiness,

Protein droplet actuation on superhydrophobic surfaces: A new approach toward anti-biofouling electrowetting systems

© 2017 The Royal Society of Chemistry. This is an Open Access article, distributed under the terms of the Creative Commons Attribution 3.0 Unported (CC BY 3.0) licence https://creativecommons.org/licenses/by/3.0/.Among Lab-on-a-chip techniques, Digital microfluidics (DMF), allowing the precise actuation of discrete droplets, is a highly promising, flexible, biochemical assay platform for biomedical and bio-detection applications. However the durability of DMF systems remains a challenge due to biofouling of the droplet-actuating surface when high concentrations of biomolecules are employed. To address this issue, the use of superhydrophobic materials as the actuating surface in DMF devices is examined. The change in contact angle by electrowetting of deionised water and ovalbumin protein samples is characterised on different surfaces (hydrophobic and superhydrophobic). Ovalbumin droplets at 1 mg ml-1 concentration display better electrowetting reversibility on Neverwet®, a commercial superhydrophobic material, than on Cytop®, a typical DMF hydrophobic material. Biofouling rate, characterised by roll-off angle measurement of ovalbumin loaded droplets and further confirmed by measurements of the mean fluorescence intensity of labelled fibrinogen, appears greatly reduced on Neverwet®. Transportation of protein laden droplets (fibrinogen at concentration 0.1 mg ml-1 and ovalbumin at concentration 1 mg ml-1 and 10 mg ml-1) is successfully demonstrated using electrowetting actuation on both single-plate and parallel-plate configurations with performance comparable to that of DI water actuation. In addition, although droplet splitting requires further attention, merging and efficient mixing are demonstrated.Peer reviewe

HESPIDS: A Hierarchical and Extensible System for Process Injection Detection using Sysmon

Advanced Persistent Threat (APT) actors are increasingly utilizing Living-off-the-Land (LotL) cyber attack techniques to avoid detection. LotL are techniques that abuse legitimate functionality to perform malicious cyber activities. A common LotL attack technique, that is currently very difficult to detect and prevent, is malicious process injection, MITRE ATT\&CK Process Injection ID: T1055. We report on the initial results for HESPIDS: A Hierarchical and Extensible System for Process Injection Detection using Sysmon. We developed a hierarchical graph-based detection approach for accurate and automated detection for five process injection techniques in Windows clients. These techniques include four of 11 T1055 sub-techniques: DLL Injection, PE Injection, APC Injection, Process Hollowing, and a T1056 sub-technique: API Hooking (T1056.004). Our novel detection approach exhibits, within the limitations of our small testing environment, very high sensitivity and specificity. HESPIDS demonstrates a promising avenue for development of automated detection of advanced cybersecurity threats
