Positive Identification of LSB Image Steganography Using Cover Image Comparisons

Field: Computer Science (Physical Sciences)

In this paper we introduce a new software concept specifically designed to allow the digital forensics professional to clearly identify and attribute instances of LSB image steganography by using the original cover image in side-by-side comparison with a suspected steganographic payload image. The “CounterSteg” software allows detailed analysis and comparison of both the original cover image and any modified image, using sophisticated bit- and color-channel visual depiction graphics. In certain cases, the steganographic software used for message transmission can be identified by the forensic analysis of LSB and other changes in the payload image. The paper demonstrates usage and typical forensic analysis with eight commonly available steganographic programs. Future work will attempt to automate the typical types of analysis and detection. This is important, as currently there is a steep rise in the use of image LSB steganographic techniques to hide the payload code used by malware and viruses, and for the purposes of data exfiltration. This results because of the fact that the hidden code and/or data can more easily bypass virus and malware signature detection in such a manner as being surreptitiously hidden in an otherwise innocuous image file.
[Complications associated with percutaneous renal biopsy in Spain, 50 years later].

Field: Medicine (Health Sciences)

Major complications derived from all renal biopsy during the last 18 years were observed in only 0.75-1.4 %. Major complications occurred mainly in liver transplant patients. The use of 16 G needle provided greater diagnostic yield than the 18 G and it did not cause an increase in complications.
浮力のあるガスが排出された場合の建物周辺の濃度変動,　乱流拡散構造に関する風洞実験

Field: Engineering (Physical Sciences)

A Series of wind tunnel measurements of fluctuating gas concentration near a building model was carried out using a high response FID for three cases in which the densimetric Froude Number was specified at - 8.6, 0 and 8.6 respectively. Large influence of the buoyancy effect on distributions of <c>,<c’^2> and spectrum shape of C’ was observed in the area near the tracer outlet. The structures of the turbulent diffusion fields of the cases were discussed precisely. Special attention was paid to local stability of air which changes significantly in space according to buoyant gas diffusion, so that many features of turbulent diffusion fields under stable and unstable conditions were clarified.

Investment policies of Singapore life insurers

Field: Business, Management and Accounting (Social Sciences)

The purpose of this Applied Research Project (ARP) report is to review and analyse the investment policies of life insurers in Singapore. As the society becomes more affluent, life insurance which provides protection as well as savings and investment, has become increasingly important. Life insurance companies, besides selling the more conventional policies, have Investment-Linked policies to meet the needs of the market. With the investment element becoming more important in life insurance products, returns of investments by life insurers are receiving increasing interest. It is hence important to look at the methods used by Singapore Life insurers to invest the premiums which constitutes the life insurance fund.
Disruption in structural connectivity in ventral cortex in congenital prosopagnosia

Field: Neuroscience (Life Sciences)

Congenital prosopagnosia (CP) refers to the lifelong deficit in face processing in the absence of an obvious neural deficit and in the presence of intact sensory and intellectual function. Surprisingly, imaging studies have revealed that CP individuals show normal activation in the fusiform face area (FFA) with differences from controls emerging in more anterior cortical regions, suggesting normal FFA function and a possible disruption of neural connectivity from FFA to other regions. To test this hypothesis, we examined the structural integrity of several major fiber tracts using diffusion tensor imaging (DTI) in 5 CP and 10 normal control subjects. Fiber tracking was performed using DTI studio (Mori, et al., 2002), with FA threshold of 0.20 and critical angle of 40. The fasciculi of interest (FOI) included the inferior fronto-occipital fasciculus (IFOF), the inferior longitudinal fasciculus, the forceps major and the forceps minor. The dependent measures included mean FA values within a FOI, the number of voxels that indicate the presence of a fiber, and a connectivity score derived by documenting whether the fibers in a particular FOI terminate at a predefined cortical region. The data indicate that, in contrast with the control group, there is a disruption of structural connectivity to more anterior cortical regions in the CP group. These findings provide a better understanding of the neural substrate giving rise to CP and help elucidate the role of the FFA and other cortical regions involved in normal face recognition.
Design and Synthesis of Highly Potent and Specific ABHD6 Inhibitors

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Abstract Fine‐tuning than complete disruption of 2‐arachidonoylglycerol (2‐AG) metabolism in the brain represents a promising pharmacological approach to limit potential untoward effects associated with complete blockade of monoacylglycerol lipase (MGL), the primary hydrolase of 2‐AG. This could be achieved through a/b‐hydrolase domain containing 6 (ABHD6) inhibition, which will provide a smaller and safer contribution to 2‐AG regulation in the brain. Pharmacological studies with ABHD6 inhibitors have recently been reported, where modulation of ABHD6 activity either through CB1R‐dependent or CB1R‐independent processes showed promise in preclinical models of epilepsy, neuropathic pain and inflammation. Furthermore in the periphery, ABHD6 modulates 2‐AG and other fatty acid monoacylglycerols (MAGs) and is implicated in Type‐2 diabetes, metabolic syndrome and potentially other diseases. Herein, we report the discovery of single‐digit nanomolar potent and highly specific ABHD6 inhibitors with >1000‐fold selectivity against MGL and FAAH. The new ABHD6 inhibitors provide early leads to develop therapeutics for neuroprotection and the treatment of inflammation and diabetes.
Lutein, Zeaxanthin, andmeso-Zeaxanthin in the Clinical Management of Eye Disease

Field: Medicine (Health Sciences)

Lutein, zeaxanthin, and meso -zeaxanthin are xanthophyll carotenoids found within the retina and throughout the visual system. The retina is one of the most metabolically active tissues in the body. The highest concentration of xanthophylls is found within the retina, and this selective presence has generated many theories regarding their role in supporting retinal function. Subsequently, the effect of xanthophylls in the prevention and treatment of various eye diseases has been examined through epidemiological studies, animal studies, and clinical trials. This paper attempts to review the epidemiological studies and clinical trials investigating the effects of xanthophylls on the incidence and progression of various eye diseases. Observational studies have reported that increased dietary intake and higher serum levels of lutein and zeaxanthin are associated with lower risk of age-related macular degeneration (AMD), especially late AMD. Randomized, placebo-controlled clinical trials have demonstrated that xanthophyll supplementation increases macular pigment levels, improves visual function, and decreases the risk of progression to late AMD, especially neovascular AMD. Current publications on the preventive and therapeutic effects of lutein and zeaxanthin on cataracts, diabetic retinopathy, and retinopathy of prematurity have reported encouraging results.
ABSTRACT Exploring the Causes of Frictional Wage Dispersion

Field: Economics, Econometrics and Finance (Social Sciences)

Standard search models are unreliable for structural inference of the underlying sources of wage inequality because they are inconsistent with observed residual wage dispersion. We address this issue by modeling skill development and duration dependence in unemployment benefits in a random on the job search model featuring two-sided heterogeneity. General human capital and search on the job are the main drivers behind our model’s empirical success in replicating wage dispersion (residual and overall). A realistic quantitative appraisal of search efficiencies needs to account for one third of job to job transitions resulting in wage losses. Controlling for them has important implications for the inferred sources of wage inequality. We find that the search friction accounts for around 18 percent of observed wage inequality.
Generalized geometric analysis of right circular cylindrical star perforated and tapered grains

Field: Engineering (Physical Sciences)

This paper describes criteria and formulas adopted in developing a new computer program capable of evaluating the geometric evolution of a cylindrical star grain during its combustion. This computer program, named STAR, calculates the burning perimeter (or burning area), the wet perimeter, and port area as functions of burnt thickness for a cylindrical internally cone-shaped star grain. The star configuration is defined by seven geometric parameters. These parameters can be changed along the star grain in order to simulate different internal geometric shapes. The program does not utilize a lot of computer time and it is capable of analyzing a large number of star configurations for each run. This is very useful for a geometric optimization process of the star grain. The program output is organized in a file that can be directly used as an input file for the internal ballistic program.

From this it seemed that the relative concen- trations of uric acid and o-tolidine might be important.By increasing the concentration of o-tolidine to five times that present in the original reagent2 (and using acetate instead of phosphate buffer) a plasma-uric-acid level of 10 mg. per 100 ml. has been found not to interfere, and a level of 20 mg. per 100 ml. to produce only a 2% underestimation.With this modified reagent, therefore, the true- glucose concentration of blood can now be estimated simply and accurately with the automatic analyser, as in the original manual method.It seems likely that similar modification of the reagents used in other published methods will produce the same results.-Iam, etc.,
Improving facial expression analysis using histograms of Log-Transformed Nonnegative Sparse Representation with a Spatial Pyramid Structure

Field: Computer Science (Physical Sciences)

Facial activity is the most direct signal for perceiving emotional states in people. Emotion analysis from facial displays has been attracted an increasing attention because of its wide applications from human-centered computing to neuropsychiatry. Recently, image representation based on sparse coding has shown promising results in facial expression recognition. In this paper, we introduce a novel image representation for facial expression analysis. Specifically, we propose to use the histograms of nonnegative sparse coded image features to represent a facial image. In order to capture fine appearance variations caused by facial expression, logarithmic transformation is further employed on each nonnegative sparse coded feature. In addition, the proposed Histograms of Log-Transformed Nonnegative Sparse Coding (HLNNSC) features are calculated and organized in a pyramid-like structure such that the spatial relationships among the features are captured and utilized to enhance the performance of facial expression recognition. Extensive experiments on the Cohn-Kanade database show that the proposed approach yields a significant improvement in facial expression recognition and outperforms the other sparse coding based baseline approaches. Furthermore, experimental results on the GEMEP-FERA2011 dataset demonstrate that the proposed approach is promising for recognition under less controlled and thus more challenging environment.

Here we report a reaction of the fullerene derivatives C60Ar5Cl, which enables the substitution of Cl with thiophene residues and the formation of the novel family of C1-symmetrical C60 fullerene derivatives with six functional addends C60Ar5Th. The discovered reaction provided a straightforward approach to the synthesis of previously inaccessible multifunctional water-soluble fullerene derivatives, including the compounds with antiviral activity against human immunodeficiency and influenza viruses.
Information about Tummy Time in infants available on the Internet

Field: Health Professions (Health Sciences)

Objective: This study evaluated Tummy Time recommendations in patient education materials and informal sources found on the Internet. Methods: Patient education materials, available from health professionals online, and informal sources, found outside of healthcare, were evaluated for consistency with evidence-informed recommendations. Patient education materials were also evaluated for readability and visual presentation. Results: Twelve sets of patient education materials were included in the top 20 search results. Only one of them addressed all the evidence-informed recommendations accurately. Fifty informal sources were included in analysis, ranging from search rank #1 to #57. Nearly half of the informal sources were judged fully consistent with evidence-informed recommendations. Counter to best practice recommendations, two-thirds of the patient education materials were written above the reading level expected of a student with no more than an elementary school education. All used strategies to enhance clarity, although none met all standards for visual presentation. Conclusion: Although some good resources are available, healthcare providers should exercise caution when selecting or recommending patient education materials online, even when they are available from healthcare professionals. Parents turning to the Internet will find accurate information. However, to develop a comprehensive understanding, they may need to visit multiple sites. Practice Implications: Healthcare professionals are responsible for providing or directing their clients to reliable, comprehensive sources of information, and for being aware of the quality of information they may discover through their own searches. Healthcare websites are responsible for communicating clearly and comprehensively with their clients and the public. Some parent education materials require revision for readability, formatting and consistency with Tummy Time recommendations.
Expression of Dual Euler Parameters Using the Dual Rodrigues Parameters and Their Application to the Screw Transformation

Field: Mathematics (Physical Sciences)

Dual numbers and dual vectors are widely used in spatial kinematics [3,5- 15,18]. Plücker line coordinates of a straight line can be represented by a dual unit vector located at the dual unit sphere (DUS). By this way, the trajectory of the screw axis of a rigid body in 3 R (the real three space) corresponds to a dual curve on the DUS. This correspondence is done through Study Mapping [8,9]. Conversely a dual curve on DUS obtained from the rotations of the DUS represents a rigid body motion in 3 R [8]. The dual Euler parameters are used in defining the screw transformation in 3 R [8], but originally in this paper these parameters are constructed from the Rodrigues and the dual Rodrigues parameters [15].

Peer Review #1 of "The use of audio self-hypnosis to promote weight loss using the transtheoretical model of change: a randomized clinical pilot trial (v0.2)"

Field: Medicine (Health Sciences)

Background.Few studies suggest the use of hypnosis in weight loss may be beneficial, especially when in conjunction with other lifestyle modifications or cognitive behavioral therapy.The primary aim of this study was to determine the ability of self-hypnosis audiotape to promote weight loss by meaning its effects on the Transtheoretical Model of Change stages and processes.Methods.This study is a 3-week randomized doubleblinded parallel controlled trial among adults who have overweight or obesity.The intervention group listened to a self-hypnosis audio file while the control group listened to a placebo audio file.Results.Forty-six participants completed the 3-week follow-up visit.There was no association between progression across stages of change and self-hypnosis (X2(2, 46) = 1.909, p-value=0.580).Gender, baseline BMD, and baseline S-weight had no effect on the association between stage change progression and self-hypnosis.The mean difference in weight at three weeks was -0.63±0.43Kg in the hypnosis group and 0.0±1.5 Kg in the control group, independent t-test, p= 0.148.Conclusion.Self-hypnosis was not associated with a progression in the TTM's stages of change or with weight loss after three weeks.As this pilot study was underpowered, further research with larger sample size and an examination of the effect of various self-hypnosis content and duration is recommended.
The relationship between left ventricular mass index and body composition in new-diagnosed hypertensive patients

Field: Medicine (Health Sciences)

Cardiovascular disease (CVD) is considered a public health burden and most common cause of mortality in all over the world. The latency time for developing CVD may be several decades. the objective of this study was to examine the relationship between body composition and Left Ventriculare Mass Index (LVMI) in newly diognosed hypertensive patients.We enrolled 120 new-diagnosed hypertensive patients (mean age 45 ± 8 years) who admitted to our nephrology clinic. Body fat percentage (BFP) was measured by bioelectrical impedance (BIA). Echocardiography examinations were performed for all patients.Mean values of Waist hip ratio, Body mass ındex, Body fat percentage, Systolic blood pressure, Diastolic blood pressure were significantly higher for females than males (all p values <0.05). The female patients had higher LVMI than male patients (94.8 ± 13.1 vs 89.2 ± 14.6, p < 0.05). The study patients were divided into 3 groups according to their BFP defined by BIA. Group 3 patients, who exhibited higher body fat, had significantly higher BMI (p < 0,05), total leukocyte count (p < 0.05), CRP (p < 0.05), triglyceride (p < 0.05), and female predominance. Group 3 patients were statistically older than group 1 patients (46.2 vs. 40.6 years, p < 0.05). Additionally, LVMI levels were higher in Group 3 than Group 1 (p < 0.05) (Table 3). In logistic regression analysis, independent factors affecting LVMI were age, weight, gender and BFP (all p values were <0.05).BFP was associated with higher LVMI, in newly diognosed hypertensive patients. Its use results in significantly lower proportions of individuals with LVH in the population, in particular among hypertensive and the obese patients.
Structure of P-Glycoprotein Reveals a Molecular Basis for Poly-Specific Drug Binding

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

P-glycoprotein (P-gp) detoxifies cells by exporting hundreds of chemically unrelated toxins but has been implicated in multidrug resistance (MDR) in the treatment of cancers. Substrate promiscuity is a hallmark of P-gp activity, thus a structural description of poly-specific drug-binding is important for the rational design of anticancer drugs and MDR inhibitors. The x-ray structure of apo P-gp at 3.8 angstroms reveals an internal cavity of ∼6000 angstroms cubed with a 30 angstrom separation of the two nucleotide-binding domains. Two additional P-gp structures with cyclic peptide inhibitors demonstrate distinct drug-binding sites in the internal cavity capable of stereoselectivity that is based on hydrophobic and aromatic interactions. Apo and drug-bound P-gp structures have portals open to the cytoplasm and the inner leaflet of the lipid bilayer for drug entry. The inward-facing conformation represents an initial stage of the transport cycle that is competent for drug binding.
