 Das Jayanta Kumar Indian Journal of Dermatology , 2004, Abstract: A case of bullous congenital ichthyosiform erythroderma (epidermolytic hyperkeratosis or EHK) with some unusual features is described. It was diagnosed in a 6 month old girl with no family history of either EHK or focal lesions suggestive of mosaicism. The girl probably had EHK type NPS-2; but non-involvement of face and lack of foul body odor set the case apart.
 Erich M. Gaertner Journal of Skin Cancer , 2011, DOI: 10.1155/2011/645743 Abstract: Focal acantholytic dyskeratosis (FAD), epidermolytic hyperkeratosis (EHK), and Hailey-Hailey-like acantholysis (HH) represent unique histology reaction patterns, which can be associated with defined phenotypic and genotypic alterations. Incidental microscopic foci demonstrating these patterns have been identified in skin and mucosal specimens in association with a gamut of disease processes. These changes, when secondary, are of unclear etiology and significance. The following study further analyzes the incidence and association of these histologic patterns in a routine pathology/dermatopathology practice. 1. Introduction A variety of incidental microscopic cutaneous changes have been described in skin and mucosal specimens. Whether these represent spurious changes of no consequence, or true manifestations of underlying cellular alterations, remains unclear. Incidental FAD, HH, and EHK have been reported in association with a wide variety of benign and malignant skin conditions. (Table 2) Some authors believe these changes represent markers for underlying widespread cellular damage, likely from prolonged sun/ultraviolet light exposure. Several studies show an association of these changes with preneoplastic lesions and malignancy, supporting this theory. However, others cite a variety of clinical and pathologic evidence to refute this. A potential association between EHK, and possibly FAD, with atypical/dysplastic nevus has also been reported, although not uniformly. 2. Material and Methods 247 consecutive skin specimens covering a three-month period (1/04-3/04) were reviewed by the author to identify incidental foci of Hailey-Hailey-like acantholysis (HH) and focal acantholytic dyskeratosis (FAD). Subsequently, 500 consecutive skin specimens were reviewed by the author (8/08-9/08) at a different institution to evaluate for incidental foci of epidermolytic hyperkeratosis (EHK). An incidental focus was defined as a minor histologic finding occurring within a biopsy or excision specimen demonstrating a separate, primary process. All cases in which these patterns comprised the primary process were excluded. HH, FAD, and EHK patterns were defined utilizing standard diagnostic criteria. (Table 1) All cases were formalin fixed, paraffin embedded, and hematoxylin and eosin stained as per standard protocol. Table 1 Table 2: Conditions reported in association with described incidental reaction patterns. 3. Results Six cases of incidental FAD and HH were identified in the 247 skin specimens reviewed, representing 2.4% of the total reviewed. Of the six cases, three
 Bernd A. Berg Physics , 2014, Abstract: With the emergence of the Yang-Mills gradient flow technique there is renewed interest in the issue of scale setting in lattice gauge theory. Here I compare for the SU(3) Wilson gauge action non-perturbative scale functions of Edwards, Heller and Klassen (EHK), Necco and Sommer (NS), both relying on Sommer's method using the quark potential, and the scale function derived by Bazavov, Berg and Velytsky (BBV) from a deconfining phase transition investigation by the Bielefeld group. It turns out that the scale functions are based on mutually inconsistent data, though the BBV scale function is consistent with the EHK data when their low $\beta$ ($\beta=5.6$) data point is removed. Besides, only the BBV scale function is consistent with three data points calculated from the gradient flow by L\"uscher. In the range for which data exist the discrepancies between the scale functions are only up to $\pm 2$\% of their values, but clearly visible within the statistical accuracy.
 Journal of Applied Sciences , 2008, Abstract: This research present a method of 2D and 3D segmentation based on the Enhanced Hoshen-Kopelman algorithm and its extension to non-lattice structure. The main feature of this method is to combine a merging strategy of a region growing algorithm with the multiple labeling technique of the EHK algorithm for regular and non-regular lattice. An efficient reconstruction algorithm is then applied to the set of edge points for the obtained segmented regions. The latest uses 3D Delaunay weighted triangulation. The combination of these already known algorithms makes the proposed approach very fast, efficient and appropriate to volumetric segmentation and particularly the anatomical structures in MRI and CTScan images.
