In this paper, we present a study on activity functions for an MLNN (multi-layered neural network) and propose a suitable activity function for data enlargement processing. We have carefully studied the training performance of Sigmoid, ReLu, Leaky-ReLu and L & exp. activity functions for few inputs to multiple output training patterns. Our MLNNs model has L hidden layers with two or three inputs to four or six outputs data variations by BP (backpropagation) NN (neural network) training. We focused on the multi teacher training signals to investigate and evaluate the training performance in MLNNs to select the best and good activity function for data enlargement and hence could be applicable for image and signal processing (synaptic divergence) along with the proposed methods with convolution networks. We specifically used four activity functions from which we found out that L & exp. activity function can suite DENN (data enlargement neural network) training since it could give the highest percentage training abilities compared to the other activity functions of Sigmoid, ReLu and Leaky-ReLu during simulation and training of data in the network. And finally, we recommend L & exp. function to be good for MLNNs and may be applicable for signal processing of data and information enlargement because of its performance training characteristics with multiple teacher training patterns using original generated data and hence can be tried with CNN (convolution neural networks) of image processing.

This report describes two cases of juvenile hypertrophic cardiomyopathy (HCM) in which prominent bi-atrial enlargement was observed on standard 12-lead electrocardiogram, suggesting inherent predis-position to extreme enlargement and/or hypertrophy may exist in atrial myocardium in juvenile HCM. Comparative study between juvenile and adult HCM patients using a large sample size is required to confirm this hypothesis.

Objectives: According to the International Registry of Acute Aortic Dissection, >70% of patients with type-B aortic dissection (AD) have delayed aortic growth. The objective of this study was to investigate the morphologic characteristics of aortic enlargement in type-B AD. Methods: A total of 120 patients with uncomplicated acute type-B aortic dissection (uATBAD) were divided into 4 groups according to the presence of a patent or thrombosed false lumen (FL) with or without aortic enlargement. In all groups, the area of the true lumen (TL) and the FL were measured on axial computed tomography images. Results: A total of 120 uATBAD patients were evaluated: patent FL with (PE, N = 28, 23%) or without aortic enlargement (PU, N = 17, 14%) and thrombosed FL with (TE, N = 34, 28%) or without enlargement (TU, N = 41, 34%). The initial aortic diameter was not significantly different among the 4 groups (PE vs. PU = 39 ± 8 vs. 37 ± 10 (p = 0.354);TE vs. TU = 38 ± 6 vs. 37 ± 6 (p = 0.391)). The area of the FL tended to be larger in the PE group. In contrast, the area of the TL was significantly larger in the TE group. Late outcomes of uATBAD treated with optimal medical treatment were acceptable. Conclusions: In patients with uATBAD and a thrombosed FL, the patients with aortic enlargement tended to be increased TL size. In contrast, in patients with a patent FL, the patients with aortic enlargement tended to be increased FL size.

Objective: To determine the incidence of carcinoma in patients with asymmetrical tonsillar enlargement. Study Design: A clinical retrospective case series based on medical records of our medical complex. Results: During a two-year period, 990 patients underwent tonsillectomy at Salmaniya Medical Complex (SMC). 59 (5.9%) of those patients had asymmetrical enlargement of their tonsils, three of whom had suspicious clinical findings at presentation. The latter were found to have tonsillar malignancy on histopathological testing. Malignancy was excluded in all other specimen. Conclusions: Since the incidence of malignancy in asymmetrical tonsils is negligible in the absence of other associated risk factors, watchful waiting may be appropriate prior to any surgical intervention. Diagnostic tonsillectomy is indicated in patients with asymmetrical tonsillar enlargement with associated suspicious clinical findings, including cervical lymphadenopathy and rapid tonsillar enlargement.

In the context of an impending dam failure, quick evaluation of dam breach flood is necessary. Previous studies provided an approach to calculate the dam breach hydrograph using an Excel spreadsheet based on the improved soil erosion model and numerical algorithm. However, calculation of the breach lateral enlargement requires the modeling of the successive collapse of the breach banks. It is time-consuming with special training, which is difficult to provide during an emergency. This study proposes that the lateral enlargement process can be modeled using a hyperbolic relationship with sufficient accuracy. Consequently, field engineers can perform the dam breach analysis along with the sensitive study for a target case within 1 h in an Excel spreadsheet which is self-tutorial. This paper presents this easy and quick approach based on only fifteen input parameters that can be determined based on the experience. This approach can also be used for the preliminary study when a dam safety planning work is undertaken.
