Abstract:
The work reported on is an extension of work done in Washington State to examine the systematic occurrence and variability in pavement mat density. The focus will be on the extent of the pavement that is affected by variable density due to temperature differentials and the fact that randomly based testing does not identify the occurrence of cyclic density differentials. Temperature differentials 14°C (25°F) or greater generally cannot be compacted to the same level of density as the surrounding mat and therefore lead to significant density differentials (increase in air voids of 2% or more).

The number of M. grisea isolates from each field utilized for virulence testing varied from 28 to 47.

Abstract:
Using extensive Canadian longitudinal data from the years 1969–71, the authors estimate union-nonunion wage differentials of 12–14 percent for 1969 and 13–16 percent for 1970. These estimates are not adjusted for selectivity because three different tests to identify selectivity yield no evidence of selectivity bias. The authors argue that although testing for selectivity is often essential, selectivity adjustments have resulted in greatly inflated estimates of union-nonunion wage differentials in some studies and should therefore be used with caution.

AbstractThe paper explores the determinants of yield differentials between sovereign bonds, using euro-area data. There is a common trend in yield differentials, which is correlated with a measure of aggregate risk. In contrast, liquidity differentials display sizeable heterogeneity and no common factor. We propose a simple model with endogenous liquidity demand, where a bond’s liquidity premium depends both on its transaction cost and on investment opportunities. The model predicts that yield differentials should increase in both liquidity and risk, with an interaction term of the opposite si

Abstract Current pathologic diagnosis of benign and neoplastic bone marrow disorders relies in part on the microscopic analysis of bone marrow aspirate (BMA) smears and manual counting of nucleated cell populations to obtain a cell differential. This manual process has significant limitations, including the limited sample of cells analyzed by a conventional 500-cell differential compared to the thousands of nucleated cells present, as well as the inter-observer variability seen between differentials on single samples due to differences in cell selection and classification.

Mixed model methods allow genetic merit to be compared directly for pigs measured in different environments or generations. They take into account genetic relationships among all individuals in the population, and allow continuous selection throughout the animal's life. The advantage is more accurate selection in larger populations. The risk is that selection decisions are decentralised to many different sites, requiring a high degree of supervision.In 1986 a “group nucleus” using BLUP and AI was established for a pig dam line in order to improve both litter size and lean growth.

Abstract:
One of the issues regarding the misclassification in case-control studies is whether the misclassification error rates are the same for both cases and controls. Currently, a common practice is to assume that the rates are the same (“non-differential” assumption). However, it is suspicious that this assumption is valid in many case-control studies. Unfortunately, no test is available so far to test the validity of the assumption of non-differential misclassification when the validation data are not available. We propose the first such method to test the validity of non-differential assumption i

Myeloproliferative neoplasms include a heterogeneous group of stem cell disorders with overproduction of myeloid cells. They have very different clinical courses and prognosis and are amenable to specific targeted therapy. A prompt and accurate diagnosis is therefore very important. Genetic characterisation plays an important role in diagnosis and classification of these disorders. BCR-ABL1fusion gene and JAK2V617F mutation are the particular major molecular markers to be detected because of availability of targeted therapy.

Most of the techniques that achieve differential privacy are based on a judicious use of randomness. However, reasoning about randomized programs is difficult and error prone.

Benefits of this enhancement to brush seal include avoiding localized rubs on the rotor, which reduces heating of a local spot and resulting rotor bow and instabilities.

Full text
Abstract:
This report details the laboratory testing program conducted to assess the operating range of the spot-weldable vibrating wire (VW) strain gauges with a specific focus on most commonly used strain gauges for pipeline monitoring. These strain gauges are commonly used by the pipeline operators for long-term monitoring of a change in the pipe strain due to geohazard activities. The primary goal of the laboratory testing program was to assess the response of these strain gauges within the operating range and their behavior as they approach or exceed the manufacturer-specified operating range.

Abstract:
This project investigates experiences of racism in Uber, among both riders and drivers in Melbourne, Australia. The research was conducted between November 2022 and February 2023, and consisted of two case studies: Case study 1 investigated racism in the experiences of Uber riders (passengers)using field testing methodology. It generated the first Australian data on differential outcomes for Uber riders across three ethnic groups: white Australian, East Asian Australian and African Australian. It also provided data on thegeographic distribution of the rides based on the ethnicity of the riders

Yunovich and Thompson. L51886 Performance of Magnesium Anodes. Pipeline Research Council International, Inc. (PRCI), 2003. http://dx.doi.org/10.55274/r0010391.

Full text
Abstract:
Magnesium anodes are provided to the corrosion control industry by a number of domestic and international manufacturers and distributors. Due to the difficulty and time involved in performance testing, anode composition is commonly the only criterion used for quality control by the end users. However, experience has shown that compliance of the anode chemical composition with the ASTM B843 Standard Specification for Magnesium Alloy Anodes for Cathodic Protection can be misleading and does not always differentiate between the anodes of different quality. Thousands of magnesium anodes are produc

Sánchez, Gabriel, Ricardo N. Bebczuk, and Sebastián Auguste. Firm Size and Credit in Argentina. Inter-American Development Bank, 2013. http://dx.doi.org/10.18235/0011468.

Full text
Abstract:
The goal of this paper is to study the link between bank credit (and internal funding) and average firm size in Argentina. Besides the fact that economic growth tends to go hand in hand with larger firm size, the topic is of particular interest because of the severe credit crunch in Argentina in the aftermath of the 2001-2002 financial crisis. To this end, a novel three-digit industry-level dataset spanning the 2000-2010 period was constructed. The results confirm the expected positive impact of credit supply on average firm size. Furthermore, the study expands on common knowledge by testing t

Full text
Abstract:
Transmission and storage operations frequently move natural gas using reciprocating compressors that may generate flow pulsations. Most measurement systems cannot accurately measure the flow rate of a pulsating gas stream, and the resulting errors can cause inaccurate gas volumes and accounting imbalances. A previous PRCI research project tested whether recent advances in ultrasonic meters may allow them to function without measurement error in pulsating flows. This project expanded on the previous work and tested similar ultrasonic meters to look for relationships between ultrasonic meter tra
