The diagnostic performances of three commercially available recombinant immunoblot assays (RIBAs) for anti-hepatitis C virus antibody were evaluated on 50 ORTHO-HCV RIBA-2 (RIBA-2)-indeterminate serum samples. Concordant interpretations were obtained with the three tests in 60% of the samples, with 56% positive, 2% indeterminate, and 2% negative results. Considering test performance in regard t...

Bordetella pertussis testing performed using real-time polymerase chain reaction (RT-PCR) is interpreted based on a cycle threshold (Ct) value. At Public Health Ontario Laboratories (PHOL), a Ct value <36 is reported as positive, and Ct values ≥36 and <40 are reported as indeterminate. PHOL reported indeterminate results to physicians and public health units until May 2012, after which these re...

BACKGROUND The sensitivity of interferon-gamma release assays (IGRAs) in the detection of Mycobacterium tuberculosis infection could be affected by conditions of immune dysregulation. For this reason, diabetes mellitus (DM) may increase the frequency of indeterminate results of IGRAs. However, there have been inconsistent reports of role of DM on indeterminate IGRA results. METHODS We retrosp...

This paper presents a semantics for non-deterministic concurrent constraint programming languages. The semantics address the issues of giving an adequate treatment of non-terminating computations, in particular with fairness and liveness, and giving a compositional semantics, where the meaning of a recursively deened program is obtained as a xpoint. We present a simple concurrent constraint pro...

Introduction What is your degree of belief that the Democrats will win the next presidential election in the USA? If you report a sharp number, we will question you further. For example, if you report a credence of 0.6, we will ask whether you really mean 0.6000..., sharp to infinitely many decimal places. If you are anything like us, your credence is sharp only up to one or two decimal places....

Bayesian advocates of expected utility maximization use sets of probability distributions to represent very different ideas. Strict Bayesians insist that probability judgment is numerically determinate even though the agent can represent such judgments only in imprecise terms. According to Quasi Bayesians rational agents may make indeterminate subjective probability judgments. Both kinds of Bay...

In this paper we propose a new, more appropriate definition of regular and indeterminate strings. A string is one that “isomorphic” to whose entries all consist single letter, but which nevertheless may itself include containing multiple letters. not said be indeterminate. We begin by proposing new model for the representation strings, or indeterminate, then go on describe linear time algorithm...

OBJECTIVES/HYPOTHESIS Gene expression classifiers can safely reduce diagnostic thyroid surgery for fine-needle aspiration cytology (FNAC) indeterminate thyroid nodules. STUDY DESIGN Retrospective review, single-institution, single-practice surgeon. METHODS Three-year retrospective review of indeterminate FNAC that went on to gene expression classifier testing. RESULTS A total of 520 patie...

This paper describes a new kind of language bias, S-structural indeterminate clauses, which takes into account the meaning of predicates that play a key role in the complexity of learning in structural domains. Structurally indeterminate clauses capture an important background knowledge in structural domains such as medicine, chemistry or computational linguistics: the specificity of the compon...

BACKGROUND Follicular thyroid carcinoma cannot be distinguished reliably from benign follicular neoplasia by fine needle aspiration (FNA) biopsy. Given an estimated 20% risk of malignancy, many patients with indeterminate FNA biopsies require thyroidectomy for diagnosis. Some centers have shown significant discordance when a second pathologist evaluates the same FNA biopsy. We sought to determi...
