Disruptive coloration tricks the human eye – a study of detection times of two near-similar targets in natural backgrounds

Our understanding of camouflage, in military as well as in evolutionary perspectives, has been developing over the last 100 years. In that period of time several underlying principles have emerged. It has turned out in the recent decade that background pattern matching alone may not be sufficient to conceal targets because of the ubiquitous and revealing information contained by the edges of a target. In this paper we have studied one concealment strategy, the so-called disruptive coloration, further as it predicts that high contrast patches placed at the target’s outline will impede detection, by creating false target edges when exposed to the observer. Such disruptive coloration is contra-intuitive as it may impede detection in spite of the fact that the patches themselves may be poorly concealed. In military environments the “disruptive approach” within camouflage has been textbook material for decades. Still, very little has been reported, supporting this idea, especially when it comes to the concealment of human targets in natural sceneries. We report here experimental evidence from a field study, containing detection data from 12 unique natural scenes (5 testing the disruptive effect, 7 as reference tests), with both human targets and human observers, showing that disruptively colored camouflage patches along a human’s outline (its head) may increase detection time significantly as when compared to a similar (human) target concealed only with background matching. Hence, our results support the idea that disruptive coloration may impede detection and similarly that the best concealment is achieved when disruptive coloration is added to a target that matches the background (reasonably) well. This study raises important question to the current understanding of human vision and concealment as well as to any approach to describe the human visual system mathematically.
EFFECT OF DIETARY MANGO SEED KERNEL (MANGIFERA INDICA) AS PARTIAL REPLACEMENT OF CORN ON PRODUCTIVE AND PHYSIOLOGICAL PERFORMANCE OF GROWING GIMMIZAH COCKERELS

An investigation was undertaken to study the effects of feeding mango seed kernel (MSK) as partially substituting of yellow corn on productive performance and physiological parameters of Gimmizah cockerels. A total number of 100 Gimmizah cockerels aged 28 days were distributed into four groups. Each group was represented by five replicates (5 cockerels per rep.) from 4 -16 wk of age. The first group (control) fed the basal diet. The second, third and fourth groups were fed the basal diet with the substitution of yellow corn with MSK with 10, 15 and 20%, respectively. Body weight and body weight gain were increased when used 10% level of MSK. Feed consumption was significantly decreased and feed conversion was significantly improved overall period for 10% MSK. Carcass characteristics had not affected. While, blood constituents (Hb, PCV%, RBCS, and WBCS counts) were significantly improved. Lymphocyte (L) count for birds fed 10 and 15% MSK was significantly increased and heterophils (H) count and H/L ratio was significantly decreased. The immunological status was significantly improved due to an increase in globulin, IgG and IgM for cockerels fed diets containing the MSK levels (10%,15%). Plasma cholesterol, CK and MDA was significantly decreased by increasing MSK levels. Serum alkaline phosphatase (ALP) activity was significantly reduced when a cockerel fed diet containing 10 and 15% MSK. Bacterial count in the intestine and in fresh breast and thigh meat were decreasing by increasing MSK levels. All MSK levels used were shown better economic efficiency than the control group. The relative economic efficiency of 10% MSK replacement of corn increased with 48% than the control group. It could be concluded that MSK can be used up to 10% without any adverse effect on performance and improve blood parameters and the economic efficiency of Gimmizah cockerels during the growing period.
The Contextualization of Philanthropic Hadiths at PKU Muhammadiyah Hospital , Yogyakarta

Philanthropic hadiths are very interesting for contextual understanding in order to respond to social problems that occur in the community such as poverty and health problems which unwittingly increase day to day. This paper aimed to present philanthropic traditions about PKU Muhammadiyah hospital. The method used by researcher was analytical descriptive by using the method of socio-historical approach and Max Weber's social theory framework. The findings in this study were: First, philanthropic traditions of the hospital was delivered by the Prophet from the Companions of the Prophet around one hadith assisted by other hadiths. Second, contextualization of hadith understanding resulted in the formulation of its name; previously named Polyclinic. Muhammad Sudja considered that Muhammadiyah has not had a hospital which handled needy people. Third, the roles of the PKU Muhammadiyah hospital are very large in the terms of public health services such as medical treatment, social services and in handling disasters. Fourth, the philanthropic movement conducted by the hospital are based on religious doctrines originating from Quran and al-Sunnah al-Maqbūlah so that it can realize the noble ideals of the Indonesians, namely the true Islamic community; the main, justice, safe and prosperous society, and hence blessed by Allah SWT.
Relative frequencies of CFTR mutations in The Netherlands: Regional variation is present even in a small country

Cystic fibrosis (CF) is one of the most common autosomal recessive disorders in white populations. Significant regional differences of CF mutations among affected individuals have been reported. We studied the geographic distribution of the relative frequencies of the three most common Dutch CF mutations, ∆F508, A455E, and G542X, by analyzing data on residences of CF patients. Significantly higher relative frequencies of the A455E mutation and the G542X mutation were observed in the South-west and the South-east, respectively. For the ∆F508 mutation a rather uniform distribution of relative frequencies was found. The results of our study show that even in a small country like The Netherlands certain CF mutations may be more common in one region than in another.
A Review of Personality Type D on Cardiovascular Disease Patients

Introduction: The type of personality that a patient has as a psychosocial factor has been associated with the incidence and progression of cardiovascular disease. The aim of the study was to review the evidence and correlation between personality type and the development of cardiovascular disease. Methods: Articles were searched for using the PRISMA approach in the CINAHL, Science Direct and Scopus databases, limited to the last 5 years. The articles were from 2013 to 2018 and the language used was English. The studies focused on personality type D and cardiovascular disease, and the participants were above 18 years old. Results: Most of the findings of the studies showed that individuals with a type D personality have a relationship with more severe heart disease, which relates to several physiological factors, namely emotion increase, anxiety, stress, biological factors, cognitive decline and the decrease in quality of life. Conclusion: Individuals with type D personality have a higher level of stress, significant blood pressure, higher pulse and they experience an increase in cortisol compared to non-type D personalities. Individuals who suffer from cardiovascular disease with personality type D tend to experience a more severe progression of the condition of cardiovascular disease.
Food Pantries and Stigma: Users’ Concerns and Public Support

This study compares the perception of stigma measured as social distance between users (n = 40) and non-users (n = 202) of local food pantries in the Upper Midwest. Utilizing the concept of social distance to measure social disapproval and stigma with a new Food Pantry Stigma Scale, these nonprobability results indicated that users’ perception of stigma was significantly higher than the non-using public (Cohen’s  = 1.56). These findings suggest that public support for need-based use of local food pantries in the Upper Midwest is substantially higher than those facing food insecurity anticipate.
The Growth and fosE gene expression in inulin-containing medium of two strains of Lactobacillus casei originated from the human intestinal tract

Abstract. Authors. 2019. Growth and fosE gene expression in inulin-containing medium of two strains of Lactobacillus casei originated from the human intestinal tract. Biodiversitas 20: 2758-2763. Inulin is a fructooligosaccharide consisting of a fructose monomer with β- (1,2) glycosidic linkage. The human colon cannot degrade inulin because it lacks the enzyme that degrades β- (1,2) glycosidic linkage. Lactobacillus casei strain AP is able to grow in inulin, L. casei strain AF grows gradually. The ability to grow in inulin is proposed by the fosE gene, which hydrolyzes β- (1,2) glycosidic linkage. The present study aimed to detect and measure fosE gene expression in inulin. Extracellular and intracellular inulin and fructose concentrations were calculated using high-performance liquid chromatography. The reduction of inulin concentration in L. casei strain AP was higher than that in L. casei strain AF. Extracellular fructose concentration was lower in L. casei strain AP because fructose from inulin degradation was transported into the cell. No fructose was detected inside Lactobacillus cells. The fosE gene was detected in L. casei strains AP and AF with a length of 229 bp. fosE gene expression was up-regulated 5.9-fold in L. casei strain AP and 1.7-fold in L. casei strain AF and was three times higher in L. casei strain AP than that in L. casei strain AF, suggesting that the former metabolizes inulin better than the latter.
RURAL MARKETS AND NIGERIA’S ECONOMIC DEVELOPMENT: A CASE STUDY OF SELECTED MARKETS IN BAYELSA STATE

As far as rural markets are concerned, they have a long history in Bayelsa State. Rural markets have helped to enhance the distribution of commodities that are produced in the locality with a view to broadening the local economic base. Social interaction in the rural market has also enhanced intra and inter communal harmony and by extension promoted peace and economic development. The high level of poverty and infrastructural deficit in the rural market communities engendered mass rural-urban migration with a negative impact on agricultural output and living standards. The methodology adopted a descriptive approach and covering four major rural markets in Bayelsa State, and using simple percentages estimation to evaluate data collected. Recommendations include urgent need for rural market reform and a deliberate literacy development programme as well as development of modern infrastructures in the rural communities.
What Can Predict Bubbles in Cryptocurrency Prices? Identification and explanation based on PSY test and regression models

In this paper we study variables that can predict bubbles in cryptocurrency prices. Bubble periods are detected by employing a recursive augmented Dickey-Fuller algorithm called the PSY test, developed by Phillips et al. (2015a,b). Through probit and linear regression models we study the possible predictors of the bubble periods. We utilize both detected days and the underlying test statistics produced by the algorithm as dependent variables in the analysis. Compared to other studies, we emphasize uncertainty measures as predictors and include an extended selection of cryptocurrencies. We apply panel regressions to investigate predictors across cryptocurrencies and time series regressions to study predictors for specific cryptocurrencies. We detect multiple bubble periods in all cryptocurrencies, particularly in 2017 and early 2018. The predictive ability of the variables appear to be dependent on the cryptocurrency studied. Though in general, we find that higher volatility and trading volume is positively associated with the presence of bubbles across cryptocurrencies. When it comes to uncertainty variables, the VIX-index consistently demonstrates negative relationships with bubble behavior. Furthermore, transactions and the EPU-index mostly exhibit positive associations with bubbles, but the effects are dependent on the cryptocurrency examined. In terms of bubble prediction, the probit models perform better than the linear models.
Maintenance solutions for the conservation of sunflower inflorescences

The sunflower (Helianthus annuus L.) is an ornamental plant of great acceptance in the market, however, as cut flower has its limited useful life, about 3 to 5 days at room temperature. In order to prolong shelf life and preserve post-harvest quality was evaluated the effect of maintenance solutions on sunflower cv. Oasis for 10 days storage at 25 °C. O experimento foi conduzido em delineamento inteiramente casualizado em arranjo fatorial 5x6, correspondendo a cinco tratamentos/soluções de manutenção (distilled water (control), sucrose, citric acid, gibberellic acid and benzylaminopurine to 5%) and six evaluation times (0, 2, 4, 6, 8 and 10 days). The effect of treatments on fresh mass, inflorescence turgescence, stem curvature, relative petal water content, respiratory rate and carbohydrate content was investigated. The results showed that the solutions with sucrose and gibberellic acid significantly (p<0.05) preserved the quality of the inflorescences as a function of the control of respiratory activity and water absorption, thereby reducing the physiological processes related to senescence. It is recommended to use sucrose 5% as a maintenance solution due to the low cost to producers and consumers.
An efficiency assessment of irrigated tomato (Solanum lycopersicum) production in the Upper East Region of Ghana

This study employed the input-oriented DEA approach with variable returns to scale assumption to assess the technical, scale, allocative and economic efficiencies of 124 randomly selected tomato farmers under irrigation in the Upper East Region using data of the 2017/2018 production season. The mean technical efficiency and scale efficiency were 97.1 and 97% respectively with many farmers experiencing increasing returns to scale. The mean allocative and economic efficiencies were 42.1 and 41.5% respectively. Farmer’s age, tomato land size, fuel quantity, fertilizer quantity and chemical quantity (herbicide and pesticide) were all significant determinants of technical efficiency scores whereas extension visit, tomato land size and chemical quantity significantly influenced both allocative and economic efficiencies. It is recommended that agro-inputs and fuel usage for tomato farmers under irrigation in the dry season be increased to improve technical efficiency. It is also recommended that extension education to farmers on effective inputs allocation and cost minimization strategies be intensified. Key words: Allocative, economic and technical efficiency, data envelopment analysis, Tobit regression, tomatoes, Upper East Region of Ghana
RPA and Pif1 cooperate to remove G-rich structures at both leading and lagging strand

In Saccharomyces cerevisiae, the absence of Pif1 helicase induces the instability of G4-containing CEB1 minisatellite during leading strand but not lagging strand replication. We report that RPA and Pif1 cooperate to maintain CEB1 stability when the G4 forming strand is either on the leading or lagging strand templates. At the leading strand, RPA acts in the same pathway as Pif1 to maintain CEB1 stability. Consistent with this result, RPA co-precipitates with Pif1. This association between Pif1 and RPA is affected by the rfa1-D228Y mutation that lowers the affinity of RPA in particular for G-rich single-stranded DNA. At the lagging strand, in contrast to pif1Δ, the rfa1-D228Y mutation strongly increases the frequency of CEB1 rearrangements. We explain that Pif1 is dispensable at the lagging strand DNA by the ability of RPA by itself to prevent formation of stable G-rich secondary structures during lagging strand synthesis. Remarkably, overexpression of Pif1 rescues the instability of CEB1 at the lagging strand in the rfa1-D228Y mutant indicating that Pif1 can also act at the lagging strand. We show that the effects of the rfa1-D228Y (rpa1-D223Y in fission yeast) are conserved in Schizosaccharomyces pombe. Finally, we report that RNase H1 interacts in a DNA-dependent manner with RPA in budding yeast, however overexpression of RNase H1 does not rescue CEB1 instability observed in pif1Δ and rfa1-D228Y mutants. Collectively these results add new insights about the general role of RPA in preventing formation of DNA secondary structures and in coordinating the action of factors aimed at resolving them.
Systemic Risk Analysis of Chinese Banking System Based on Dynamic Vine Copula Models

This paper proposes a new model for dynamic high-dimensional conditional distributions, facilitating the measure of systemic risk. Our proposed models draw on ideas from the literatures on modeling conditional dependence using vine copulas and on the recent work on general dynamic copula models. Employing the rolling window method, we consider three kinds of dynamic vine copulas: time-varying copulas, changing copula types, and the changing vine structures. Using the equity data of 16 Chinese listed banks over the period 2010 to 2018, we estimate the dynamic vine copula model and find this model is robust for different lengths of rolling window. In addition, we apply this dynamic vine copula model to analyze the systemic risk of Chinese banking system. In perspectives of both the banking system and the individual banks, we consider several benchmark systemic risk measures. We also calculate the concordance dependence measure, Kendall’s tau, from our dynamic vine copula model. Results show that the systemic risk during the Chinese stock market crash in 2015 is higher than that during other times, and large banks (e.g. global systemically important banks) generally rank higher than others, especially during the market crash, indicating that the bank size is generally positively relative to the systemic importance. Interestingly, we also find that the systemic risk in early 2015 (corresponding to the Chinese stock market boom) is higher than other relatively normal times.
Inhibition of Activin/Myostatin signalling impairs mouse testis

Numerous approaches are being developed to promote post-natal muscle growth based on attenuating Myostatin/Activin signalling for clinical uses such as the treatment neuromuscular diseases, cancer cachexia and sarcopenia. However there have been concerns about the effects of inhibiting Activin on tissues other than skeletal muscle. We intraperitoneally injected mice with the Activin ligand trap, sActRIIB, in young, adult and a progeric mouse model. Treatment at any stage in the life of the mouse rapidly increased muscle mass. However at all stages of life the treatment decreased the weights of the testis. Not only were the testis smaller, but they contained fewer sperm compared to untreated mice. We found that the hypertrophic muscle phenotype was lost after the cessation of sActRIIB treatment but abnormal testis phenotype persisted. In summary, attenuation of Myostatin/Activin signalling inhibited testis development. Future use of molecules based on a similar mode of action to promote muscle growth should be carefully profiled for adverse side-effects on the testis. However the effectiveness of sActRIIB as a modulator of Activin function provides a possible therapeutic strategy to alleviate testicular seminoma development.

Purpose: The purpose of this study was to explore and analyze the latest trends in domestic research related to integrated nursing care service and to present a practical direction for future research. Methods: This study was focused on domestic nursing research related to integrated nursing care service as published in journals until March 20, 2019. After reviewing the quality of the papers, 34 papers were finally selected for analysis. In order to analyze the overall trends, the analysis was reviewed by year, source, research design, and subjects, and content analysis was used to identify trends by topic. Results: From the content analysis, the top categories were divided into nurses’ view and patients’ view, with both nurses’ view and patients’ view for the subcategories of 'input', 'process' and 'output' respectively. From both the nurse and patient view, the sub-category ‘input’ included ‘service environment’, ‘process’ and ‘service throughput’ and for the 'output' subcategory, three subjects, 'performance', 'service-related perception change' and 'social psychological change' were derived from the nurses’ view, and two subjects 'performance' and ‘service-related perception change’ were derived from the patients’ view. Conclusion: In order for future studies to provide practical basic data for stable settlement and improvement of integrated nursing care service, it is necessary to develop and study various aspects without bias, and in a balanced and integrated manner.
Determinants of Women Entrepreneurs’ Performance in Ethiopia (Evidence from Hawassa City Administration)

This study is conducted to assess the determinants of women entrepreneurs’ performance: the case of Hawassa City Administration, Ethiopia. The study employed an explanatory research design with quantitative and qualitative research approaches. The required data were collected from 278 selected women entrepreneurs by adopting a multistage sampling technique. The data collected through questionnaire were analyzed using SPSS software version 21. Inferential statistics such as correlation and multiple linear regression were applied. The data collected through key informant interview was analyzed qualitatively using narration for triangulation. The findings of the study showed that educated women had better entrepreneurship performance since they can easily use technologies and can get management experience easily. In the same way, women entrepreneurs experience to increase their profitability. Likewise, having sufficient start up capital for business, access to credit to expand an existing business, having sufficient working capital, and having had collateral to get credit are significant factors that affect women entrepreneurs’ performance. Equally, having high production capacity due to available capital, delivering a product that meets customers need with a fair price, having convenient display room and selling premises, and having good market linkages are significant factors that affect women entrepreneurs’ performance. Furthermore, having the desire for achievement, independence, wealth and having self-discovery and job satisfaction are significant determinants of women entrepreneurs’ performance. Therefore, the researcher recommends Hawassa city administration in collaboration with other NGO who were working with women should give continuous training to enable them to be more productive. Likewise, the financial institutions in the city should arrange long-term financial credit for women entrepreneurs.
