Advanced Materials Technologies, EarlyView.Integrated Au nanosheet sensor array enables simultaneous inference of gas concentration and flow rate via deep neural network analysis, without external flow control. ABSTRACT Gas sensor responses are considerably affected by gas flow rates, thereby inhibiting the accurate detection of target gas concentrations in variable‐flow applications such as ...

Apreçamento de opções de IDI usando distribuições hiperbólicas generalizadas
Economia Aplicada, 2003 This paper proposes an option price model for the Brazilian IDI option of BM&F. The model considers that the forward price's return of the IDI follows a Generalized Hyperbolic (GH) distribution, and then is obtained an option pricing formula similar to ...

Modeling Heavy-Tailed Stock Index Returns Using the Generalized Hyperbolic Distribution [PDF]
In the present study, we estimate the parameters of the Generalized Hyperbolic Distribution for a series of stock index returns including the Romanian BETC and indexes from other two Eastern European countries, Hungary and the Czech Republic.

Analyzing the use of generalized hyperbolic distributions to value at risk calculations
Economia Aplicada, 2005 The goal of this paper is to analyze the use of the Generalized Hyperbolic (GH) Distributions to model the US Dollar/Brazilian Real exchange rate in a way to produce more accurate VaR (Value at Risk) measurements.

MixtureMissing: An R Package for Robust and Flexible Model-Based Clustering with Incomplete Data
Journal of Statistical SoftwareThe R package MixtureMissing performs model-based clustering on data sets with values missing at random, aiming to identify homogeneous groups of observations. In model-based clustering, the data within each cluster follow a specific distribution. In the

Moments of the generalized hyperbolic distribution [PDF]
In this paper we demonstrate a recursive method for obtaining the moments of the generalized hyperbolic distribution. The method is readily programmable for numerical evaluation of moments.

Advanced Materials Technologies, EarlyView.ABSTRACT Quantifying oral polymorphonuclear neutrophils (oPMNs) is a clinically validated approach for assessing periodontal inflammation. However, current methods, such as manual hemocytometry and flow cytometry, are time‐consuming (>3 h), require invasive sampling, and depend on staining and complex instrumentation, making them unsuitable for point ...

On the Distributional Characterization of Log-returns of a World Stock Index [PDF]
In this paper we identify distributions which suitably fit log-returns of the world stock index (WSI) when these are expressed in units of different currencies.

Hyperbolic operators in spaces of generalized distributions
Rocky Mountain Journal of Mathematics, 1986 The main result of the paper is a characterization of hyperbolic operators in the space \({\mathcal D}'_{\omega}\) of Beurling generalized distributions. The notion of hyperbolicity with respect to \(t>0\) and \(t0.\) (ii) \(S\) is invertible and there exist constants \(C\), \(A\), \(M\) and \(A_ 1\) so that \[ \Im \tau \leq A(| \Im z| +\frac{1}{2(3 ...
