The application of Artificial Neural Network for the assessment of thermal properties of multi-layer semiconductor structure

In this paper, the solution of the problem of identification of thermal properties of investigated multi-layer structure is presented. In order of that, artificial neural network was used to find the set of thermal properties for which the complex contrast characteric derived fits the best to the one evaluated basing upon experimenatal data.Comment: Submitted on behalf of TIMA Editions (http://irevues.inist.fr/tima-editions

The method of non-linear distortions elimination in photoacoustic investigation of layered semiconductor structure

This paper presents the consideration of the presence and the influence of non-linear distortion of photo-acoustic measurement set-up on the results of thermal properties analysis for the multi-layer semiconductor structure. The authors propose a method which will eliminate such an influence

Assessing non-Mendelian inheritance in inherited axonopathies

PURPOSE: Inherited axonopathies (IA) are rare, clinically and genetically heterogeneous diseases that lead to length-dependent degeneration of the long axons in central (hereditary spastic paraplegia [HSP]) and peripheral (Charcot–Marie–Tooth type 2 [CMT2]) nervous systems. Mendelian high-penetrance alleles in over 100 different genes have been shown to cause IA; however, about 50% of IA cases do not receive a genetic diagnosis. A more comprehensive spectrum of causative genes and alleles is warranted, including causative and risk alleles, as well as oligogenic multilocus inheritance. METHODS: Through international collaboration, IA exome studies are beginning to be sufficiently powered to perform a pilot rare variant burden analysis. After extensive quality control, our cohort contained 343 CMT cases, 515 HSP cases, and 935 non-neurological controls. We assessed the cumulative mutational burden across disease genes, explored the evidence for multilocus inheritance, and performed an exome-wide rare variant burden analysis. RESULTS: We replicated the previously described mutational burden in a much larger cohort of CMT cases, and observed the same effect in HSP cases. We identified a preliminary risk allele for CMT in the EXOC4 gene (p value= 6.9 × 10-6, odds ratio [OR] = 2.1) and explored the possibility of multilocus inheritance in IA. CONCLUSION: Our results support the continuing emergence of complex inheritance mechanisms in historically Mendelian disorders

Fast visualization of adhesion quality in layered structures with the help of beam displacement modulation method

W artykule zaprezentowano i opisano koncepcję stanowiska do szybkiej wizualizacji jakości adhezji struktur warstwowych krzem-molibden, wykorzystywanych do produkcji diod i tyrystorów mocy, metodą termo-falową w trybie modulacji przestrzennej. Opisano sposób akwizycji obrazów termo-falowych oraz parametry pomiaru, w tym parametry sygnału pobudzenia. W artykule zamieszczono przykłady obrazów termofalowych ośmiu przebadanych struktur. Wybrana struktura została porównana z obrazami zarejestrowanymi metodą mikrofonową.The paper presents an idea of the measurement setup for fast visualization of adhesion quality in silicon-molybdenum structures with the help of beam displacement modulation technique. The prototype experimental set-up uses the spatial modulation technique and constant excitation power (high power continuous-wave laser) for excitating the time-changing temperature field on the object surface. This solution consists in placing the examined objects on a disc rotating with a constant angular velocity. The infrared detector is situated so as to record temperature changes with a certain delay after the excitation. The objects under investigation were silicon-molybdenum structures used for manufacturing diodes and high power thyristors. Additionally, the paper describes an idea of acquisition of thermal-wave images as well as the measurement parameters, including parameters of excitation. The thermal-wave images of the eight examined structures are shown. The image of one structure is compared with images acquired by the well-known photo-acoustic method
