Universal Barcode Detector via Semantic Segmentation

Barcodes are used in many commercial applications, thus fast and robust reading is important. There are many different types of barcodes, some of them look similar while others are completely different. In this paper we introduce new fast and robust deep learning detector based on semantic segmentation approach. It is capable of detecting barcodes of any type simultaneously both in the document scans and in the wild by means of a single model. The detector achieves state-of-the-art results on the ArTe-Lab 1D Medium Barcode Dataset with detection rate 0.995. Moreover, developed detector can deal with more complicated object shapes like very long but narrow or very small barcodes. The proposed approach can also identify types of detected barcodes and performs at real-time speed on CPU environment being much faster than previous state-of-the-art approaches

FaSTExt: Fast and Small Text Extractor

Text detection in natural images is a challenging but necessary task for many applications. Existing approaches utilize large deep convolutional neural networks making it difficult to use them in real-world tasks. We propose a small yet relatively precise text extraction method. The basic component of it is a convolutional neural network which works in a fully-convolutional manner and produces results at multiple scales. Each scale output predicts whether a pixel is a part of some word, its geometry, and its relation to neighbors at the same scale and between scales. The key factor of reducing the complexity of the model was the utilization of depthwise separable convolution, linear bottlenecks, and inverted residuals. Experiments on public datasets show that the proposed network can effectively detect text while keeping the number of parameters in the range of 1.58 to 10.59 million in different configurations.Comment: 6 pages, 8th International Workshop on Camera-Based Document Analysis & Recognitio

Gender Competence as the Most Important Component of the Teacher's Professionalism

In the modern education the attention is paid to the teacher's development and self- development of the identity, the teacher, who can be flexibly guided in the difficult social circumstances, and is professional work in the conditions of the reformed educational organization. In this regard is defined the model of development of the teacher's professional competence. The teacher has to understand the social role and functions in modern society; to aspire to the high level in development of professionalism when mastering psychology and pedagogical knowledge; to own personal qualities: insistence, pedagogical advantage, competence, professional responsibility. When forming the teacher's professional pedagogical competence it is necessary to pay attention to gender aspect. The gender perspective is one of those subjects which are interesting to modern society. Gender distinctions should be considered in educational process both in relation to trainees, and in relation to teachers. Men and woman train differently and there are essential gender distinctions in their behavioral and communicative aspects, in the solutions of many pedagogical problems and in styles of the teachers' professional activity. Our article is devoted to the analysis of this problem, which is urged not only to designate this problem, but also to develop specific conditions on its decision. DOI: 10.5901/mjss.2015.v6n3s7p9

SHORT-TERM RESULTS OF SIMULTANEOUS SURGERIES AT METASTATIC COLORECTAL CANCER

We compared the main group of patients (64 persons) underwent colon resection and liver resection, radiofrequency ablation of metastases in the liver and portal vein chemoembolization with the control group (62 persons) with the operation on the colon without intervention on the liver. The blood loss during surgery in the main group was 696.1 ± 226.3 ml and in the control group - 473.3 ± 245.9 ml (p = 0.000008). When performing hemihepatectomy blood loss during surgery was 802.9 ± 208.5 ml, and performing other liver resections - 575 ± 182.2 ml (p = 0.00005). Duration of hospital stay after the surgery in the study group was 16.8 ± 5.1 days and in the control group -14.0 ± 4.1 days (p = 0,001). Duration of hospital stay after the surgery was higher in the patients after hemihepatectomy, compared to the patients who received smaller volume liver resection -19.7 ± 3.9 versus 13.4 ± 3.8 days (p = 0,005). Postoperative complications were more frequent in the patients of the main group -18 (28.1 %) vs 10 (16.1 %). However, increasing the proportion of complications in the patients with simultaneous treatment of complications associated with the summation operations on the colon and liver operations. Performing liver resection is an independent factor contributing to the prolongation of operative time and blood loss, which increases the frequency of postoperative complications and increases duration of the patient's stay in the hospital

Toxicological Analysis of Hepatocytes Using FLIM Technique: In Vitro versus Ex Vivo Models

The search for new criteria indicating acute or chronic pathological processes resulting from exposure to toxic agents, testing of drugs for potential hepatotoxicity, and fundamental study of the mechanisms of hepatotoxicity at a molecular level still represents a challenging issue that requires the selection of adequate research models and tools. Microfluidic chips (MFCs) offer a promising in vitro model for express analysis and are easy to implement. However, to obtain comprehensive information, more complex models are needed. A fundamentally new label-free approach for studying liver pathology is fluorescence-lifetime imaging microscopy (FLIM). We obtained FLIM data on both the free and bound forms of NAD(P)H, which is associated with different metabolic pathways. In clinical cases, liver pathology resulting from overdoses is most often as a result of acetaminophen (APAP) or alcohol (ethanol). Therefore, we have studied and compared the metabolic state of hepatocytes in various experimental models of APAP and ethanol hepatotoxicity. We have determined the potential diagnostic criteria including the pathologically altered metabolism of the hepatocytes in the early stages of toxic damage, including pronounced changes in the contribution from the bound form of NAD(P)H. In contrast to the MFCs, the changes in the metabolic state of hepatocytes in the ex vivo models are, to a greater extent, associated with compensatory processes. Thus, MFCs in combination with FLIM can be applied as an effective tool set for the express modeling and diagnosis of hepatotoxicity in clinics

ЛАПАРОСКОПИЧЕСКАЯ ГАСТРЭКТОМИЯ С ЕЮНОГАСТРОПЛАСТИКОЙ

The arm of the research. To develop a way to perform the laparoscopic total gastrectomy with jejunal interposition (Longmire’s procedure).Material and methods. The study presents the technology of laparoscopic total gastrectomy with a lymph node dissection D1α and jejunal interposition. After removal of the gaster with the tumor through a mini-laparotomy (2 inch), the jejunum was cut approximately45 cm distally to the ligament of Treitz. A circular stapler was used to perform an esophago-jejunostomy with Roux-en-Y reconstruction using a standard technology. The second stage is forming a segment of the small intestine for jejunal interposition. The third stage is entering the head of the circular stapling apparatus into the stump of the duodenum on a probe retrogradely through the afferent loop of the small intestine. The fourth stage is stapled anastomosis between a free segment of the jejunum and the duodenum with the circular stapler. The procedure is finalized with hand-sewn anastomosis between the afferent and efferent loops of the small intestine.Results. The presented technology was used to perform surgery on one patient. The increase in operative time did not lead to increased intraoperative blood loss and longer post-operative bed-days. After 1 year the patient shows no evidence of a tumor progression, manifestations of reflux esophagitis, and dumping syndrome. Conclusion. The proposed technology allows laparoscopic total gastrectomy with jejunal interposition via a mini-invasive technology. Цель исследования – разработать способ выполнения лапароскопической гастрэктомии с сохранением пассажа по ДПК путём пластики сегментом тонкой кишки без формирования резервуара.Материал и методы.

Dry reforming of methane over Co–Mo/Al2O3 catalyst under low microwave power irradiation

In this work, microwave (MW) irradiation was used to activate Co/Al2O3, Mo/Al2O3, and Co-Mo/Al2O3 catalysts for dry reforming of methane (DRM) reactions. Experimental results indicate that single metallic catalysts of either Co or Mo are inactive for DRM under all the tested conditions due to their limited MW-absorbing ability. In contrast, Co-Mo bimetallic catalysts supported by Al2O3 exhibit high catalytic activity due to the formation of a magnetodielectric Co0.82Mo0.18 alloy, which plays the dual role of a good MW acceptor and the provider of active centers for the DRM reaction. The MW power level required to activate such bimetallic catalysts for DRM is significantly dependent on the molar ratio between Co and Mo. The CoMo2 catalyst (with a molar ratio of 2.0 Co to 1.0 Mo) supported on Al2O3 exhibits the best catalytic performance, converting 80% CH4 and 93% CO2 to syngas at a ratio of H2/CO of 0.80 at the total volumetric hourly space velocity (VHSV) of 10 L g-1 h-1 and MW power of 200 W. As compared to the reported C-based catalysts, the Co-Mo/Al2O3 catalyst delivers more favorable stability over 16 time-on-stream (TOS) by virtue of its intrinsic ability to absorb MW without the inclusion of auxiliary MW acceptors
