Pathologic diagnosis of malignant mesothelioma: chronological prospect and advent of recommendations and guidelines
Malignant mesothelioma is rare and difficult to diagnose. Its identification depends upon pathological investigation (cyto-histological assessment and immunohistochemistry) supported by clinical and radiological evidence. In the last decade, the standardization of diagnostic methods has become a major focus of debate among pathologists and clinicians. This has led to the writing of guidelines and recommendation for the diagnosis to achieve the goal of a standard diagnosis. In this article, a chronological view relating to the pathological diagnosis of MM is presented together with a review of guidelines/recommendation

Worthy of faith?: Authors and readers in early modernity
This chapter will consider how the traditional (classical Roman and Europeanmedieval) definition of the “author” as “one worthy of faith” (the faith of thereader, obviously) is put increasingly to the test during the early modern period, as the notion of literary writing gradually moves from epistemological (vatic) and/or ethical-rhetorical models toward what Terry Eagleton has called “the ideology of the aesthetic” – that is, toward suspension of readerly belief in the moral fidelity and intellectual credibility of the literary writer. In a classic formulation, the literary author as a distinctive “personal” and individual presence, indeed as willful demideity “making worlds,” first emerges in what we sometimes still call the Renaissance: first in the Italy of Dante and Petrarch, and then, gradually, spreads throughout the nascent vernacular traditions of western Europe. What follows will rehearse some clichés of the topic, one hopes in an appealing way, and lay out to shift the terms of the discussion in others. In particular, I will focus on the intuitively obvious, yet not always thoroughly explored, point that any notion of authorship is intricately tied to ideas, and realities, of readership. More especially, I will explore, on the one hand, the question of authorial control over the meaning of a text as this takes shape in the experience of its readers and, on the other, how such readers may either trustingly embrace the offered sense of the text or willfully recast it
Robust Simulation of a TaO Memristor Model
This work presents a continuous and differentiable approximation of a Tantalum oxide memristor model which is suited for robust numerical simulations in software. The original model was recently developed at Hewlett Packard labs on the basis of experiments carried out on a memristor manufactured in house. The Hewlett Packard model of the nano-scale device is accurate and may be taken as reference for a deep investigation of the capabilities of the memristor based on Tantalum oxide. However, the model contains discontinuous and piecewise differentiable functions respectively in state equation and Ohm's based law. Numerical integration of the differential algebraic equation set may be significantly facilitated under substitution of these functions with appropriate continuous and differentiable approximations. A detailed investigation of classes of possible continuous and differentiable kernels for the approximation of the discontinuous and piecewise differentiable functions in the original model led to the choice of near optimal candidates. The resulting continuous and differentiable DAE set captures accurately the dynamics of the original model, delivers well-behaved numerical solutions in software, and may be integrated into a commercially-available circuit simulator
Buoyancy-driven motion of a deformable drop toward a planar wall at low Reynolds number
The slow viscous motion of a deformable drop moving normal to a planar wall is studied numerically. In particular, a boundary integral technique employing the Green's function appropriate to a no-slip planar wall is used. Beginning with spherical drop shapes far from the wall, highly deformed and ‘dimpled’ drop configurations are obtained as the planar wall is approached. The initial stages of dimpling and their evolution provide information and insight into the basic assumptions of film-drainage theory

A group of subject-verb agreements: finding quantity in group and number
This study characterizes the subject-verb agreement that occurs with group of NP and number of NP. These two complex noun phrases can agree with a verb as a singular or plural noun. These two particular items were selected as number of NP has a relatively firm description of its quantification behavior described in existing literature while group of NP has not been shown to have describable rules governing its quantity. Using data collected from the Corpus of Contemporary American English (COCA), 1200 concordance lines centered on group of and number of which agree with a verb in a clause were extracted for study of several co-occurring features. Individual features such as determiners and modifiers are examined with respect to their distribution with singular or plural-agreeing verbs to identify patterns of agreement and potentially indicate trends, if not causal relationships. Some features, such as determiners preceding the first noun number, show trends with respect to the verb-demonstrated quantity of the noun phrase. Other features, such as premodifiers on either noun in group of NP do not appear to co-occur in demonstrable patterns. By creating a description of quantification in this way, this study lays the foundation for more targeted future studies of quantification in cognition, grammar, and semantics
Demonstration of an electrostatic-shielded cantilever
The fabrication and performances of cantilevered probes with reduced
parasitic capacitance starting from a commercial Si3N4 cantilever chip is
presented. Nanomachining and metal deposition induced by focused ion beam
techniques were employed in order to modify the original insulating pyramidal
tip and insert a conducting metallic tip. Two parallel metallic electrodes
deposited on the original cantilever arms are employed for tip biasing and as
ground plane in order to minimize the electrostatic force due to the capacitive
interaction between cantilever and sample surface. Excitation spectra and
force-to-distance characterization are shown with different electrode
configurations. Applications of this scheme in electrostatic force microscopy,
Kelvin probe microscopy and local anodic oxidation is discussed.Comment: 4 pages and 3 figures. Submitted to Applied Physics Letter
