HIGH CAPACITY AND OPTIMIZED IMAGE STEGANOGRAPHY TECHNIQUE BASED ON ANT COLONY OPTIMIZATION ALGORITHM

The tremendous development of digital technology, it is mandatory to address the security while transmitting information over network in a way that observer couldn’t depict it. Measures to be taken to provide the security by establishing hidden communication using steganography principle which is help to camouflage the secret information in some carrier file such as text, image, audio and video. In this era of hidden data communication, image becoming an effective tool on account of their frequency, capability and accuracy. Image steganography uses an image as a carrier medium to hide the secret data. The main motive of this article is that the uses the combination of frequency domain and optimization method inorder to increasing in robustness. In this article, Integer Wavelet transform is performed into the host image and coefficients have been transformed. ACO optimization algorithm is used to find the optimal coefficients where to hide the data. Furthermore, sample images and information having been demonstrated which proved the increased robustness as well as high level of data embedding capacity

Organisational Learning and Incident Response: Promoting Effective Learning Through The Incident Response Process

Effective response to information security incidents is a critical function of modern organisations. However, recent studies have indicated that organisations have adopted a narrow and technical view of incident response (IR), focusing on the immediate concern of detection and subsequent corrective actions. Although some reflection on the IR process may be involved, it is typically limited to technical issues and does not leverage opportunities to learn about the organisational security threat environment and to adapt incident response capabilities. Given the science of incident response is rooted in practice, it is not surprising that the same criticisms can be applied to much of IR literature. However, a review of literature in the area of organisational learning suggests that improvements can be made to the incident response process. This paper proposes that future incident response research must incorporate a learning focus, improve feedback timing on learning activities, facilitate double-loop learning and incorporate an informal learning perspective within both formal, procedural incident response processes as well as unstructured, informal environments

Non-reciprocal interactions spatially propagate fluctuations in a 2D Ising model

Motivated by the anisotropic interactions between fish, we implement spatially anisotropic and therefore non-reciprocal interactions in the 2D Ising model. First, we show that the model with non-reciprocal interactions alters the system critical temperature away from that of the traditional 2D Ising model. Further, local perturbations to the magnetization in this out-of-equilibrium system manifest themselves as traveling waves of spin states along the lattice, also seen in a mean-field model of our system. The speed and directionality of these traveling waves are controllable by the orientation and magnitude of the non-reciprocal interaction kernel as well as the proximity of the system to the critical temperature.Comment: 4 figure

Measuring supply chain complexity based on multi-criteria decision approach

This study identified twenty-two drivers that cause the complexity in supply chain. The level of such complexity is quantified by using hybrid AHP and GRA method. A case company is studied in order to demonstrate the applicability of the proposed method. The results from the case company were analyzed and it is seen that the level of supply chain complexity of the case company is 0.44, which is signifying that there is a considerable scope of improvement in terms of minimizing complexity in its supply chain. From the study outcomes, it is realized that the case company mainly needs substantial improvement on the issues of “government regulation,” “internal communication and information sharing,” and “company culture” in order to minimize the level of accompanied complexity in its supply chain.©2020 IEOM Society.fi=vertaisarvioitu|en=peerReviewed

Exenatide once-weekly is effective, well tolerated in patients with T2DM and should be a useful addition to the available range of anti-diabetes treatments

Models for Greening Urban Redevelopment Projects: A Case Study of the Blackstone Canal District in Worcester, Massachusetts

This project explored the feasibility of incorporating green infrastructure, as a supplement to gray infrastructure, into urban redevelopment projects in the Blackstone Canal District of Worcester, Massachusetts. Interviews, aerial photos and secondary research were used to assess urban runoff volumes, the projected costs of infrastructural upgrades and the savings associated with green infrastructure. Our final recommendation was that green infrastructure would provide a valuable complement to the current waste water system utilized by the city

Health service approaches to providing care for people who seek treatment for obesity : identifying challenges and ways forward

OBJECTIVE: This paper aims to identify challenges in current health service approaches to providing optimal care for people who seek treatment for obesity. Type of program or service: Health service management of obesity in Australia Methods: Drawing on lived experience, clinical and academic perspectives, and available evidence, we reflect on the current state of the healthcare system to support people seeking treatment for obesity. We suggest actions to enable effective, acceptable and equitable care for this group of people. RESULTS: Identified challenges include the complexity of care required to adequately manage obesity, existing service capability and capacity, and high out-of-pocket patient costs. LESSONS LEARNT: To address these challenges, a comprehensive response is required at all levels of the healthcare system. As a starting point, we propose eight areas of action: partner with people living with obesity; eliminate weight stigma; increase healthcare professional education, guidelines and resources; establish clear referral pathways and working partnerships; scale services to meet demand; ensure flexible and accessible service delivery; implement changes to the Medicare Benefits Schedule to increase service provision and pursue opportunities for subsidised medicines

Intestinal perforation due to adult tapeworm of Taenia: a case report and review of the literature

Taeniasis is an intestinal helminth infection due to adult tapeworms belonging to the genus Taenia. Taeniasis remains a major burden in low-income countries in Asia. We present a case of intestinal perforation caused by adult tapeworm of Taenia in a 50-year-old Nepali male. The patients presented to the hospital with severe abdominal pain and intermittent vomiting. Following clinical presentations and imaging features, gastrointestinal perforation was suspected. Surgical removal of adult tapeworm of Taenia, suspected to be T. saginata or T. asiatica, was carried out during exploratory laparotomy, which was followed by an uneventful postoperative period. In addition to case presentation, we systematically review published case reports on taeniasis-related intestinal perforation. A learning point from this case is clinician should maintain a clinical suspicion of taeniasis as a possible cause of intestinal perforation in endemic areas

Transcriptional Profiling of Endocrine Cerebro-Osteodysplasia Using Microarray and Next-Generation Sequencing

BACKGROUND: Transcriptome profiling of patterns of RNA expression is a powerful approach to identify networks of genes that play a role in disease. To date, most mRNA profiling of tissues has been accomplished using microarrays, but next-generation sequencing can offer a richer and more comprehensive picture. METHODOLOGY/PRINCIPAL FINDINGS: ECO is a rare multi-system developmental disorder caused by a homozygous mutation in ICK encoding intestinal cell kinase. We performed gene expression profiling using both cDNA microarrays and next-generation mRNA sequencing (mRNA-seq) of skin fibroblasts from ECO-affected subjects. We then validated a subset of differentially expressed transcripts identified by each method using quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Finally, we used gene ontology (GO) to identify critical pathways and processes that were abnormal according to each technical platform. Methodologically, mRNA-seq identifies a much larger number of differentially expressed genes with much better correlation to qRT-PCR results than the microarray (r² = 0.794 and 0.137, respectively). Biologically, cDNA microarray identified functional pathways focused on anatomical structure and development, while the mRNA-seq platform identified a higher proportion of genes involved in cell division and DNA replication pathways. CONCLUSIONS/SIGNIFICANCE: Transcriptome profiling with mRNA-seq had greater sensitivity, range and accuracy than the microarray. The two platforms generated different but complementary hypotheses for further evaluation

Binge eating disorder and night eating syndrome in adults with type 2 diabetes:a systematic review

Abstract Background Type 2 diabetes (T2DM) is increasing in prevalence worldwide, and is closely linked to obesity. Binge Eating Disorder (BED) and Night Eating Syndrome (NES) are eating disorders that are common in obesity, and may affect the management as well as long term outcomes of T2DM. Therefore, the aim of this review was to assess the prevalence and associations of BED or NES in adults with T2DM. Methods We conducted a systematic review. The databases MEDLINE, CINAHL and AMED were searched for articles which met the inclusion criteria; including patients > 18 years old, with T2DM, and BED and/or NES. The reference lists of included studies were also searched. Meta-analysis was not attempted due to the limited number of studies that measured the outcomes of interest. Results A total of 10 studies (2 included NES) were included in this systematic review. The number screened for BED and NES were 6527 and 1039 participants, respectively. Point prevalence was 1.2–8.0% for BED and 3.8–8.4% for NES. Patients with T2DM and BED had higher BMI than patients with T2DM without BED in the two studies that reported BMI. There was no statistically significant difference in HbA1c between patients with and without BED in the two studies that measured HbA1c. Conclusions BED and NES are common in adults with T2DM, and BED is associated with higher BMI in patients with T2DM. However, only two studies reported important outcomes measures such as BMI and HbA1c in patients with T2DM. Hence, further well-designed studies are needed to assess the impact of BED and NES in patients with T2DM. Health Care Professionals should consider the diagnosis of BED and NES in patients with T2DM
