Magnetic Properties of Edge Hydrogenated Zigzag Black Phosphorene Nanoribbon by Fe Doping

Using first-principles based on density functional theory within the GGA+U framework, we investigated the structural states, energy, and magnetic properties of edge hydrogenated Zigzag black Phosphorene Nanoribbon (H-ZPNR) with P atom substituted by Fe atom in different site. Undoped Edge hydrogenated ZPNR has no magnetic moment, however our results show that the magnetic moment of doped systems varied from 1μB to 4μB, and the coupling between the Fe atom and adjacent P atoms is either ferromagnetic or anti-ferromagnetic.
Runoff and soil erosion responses to rainfall and vegetation cover under various afforestation management regimes in subtropical montane forest

Soil erosion and runoff generation are a major concern in forest and agricultural ecosystem management. However, the tangled coeffects of rainfall and vegetation on runoff and erosion generation are regionally dependent and remain unclear in regions with high erosivity, such as Southeast China where the large‐scale afforestation is being implemented. Here, we present the 4‐year observations of runoff and erosion responses to various storms following three afforestation (assisted natural regeneration [ANR; windrowing harvest residues on surface]; Chinese fir cultivation [YCF]; and Castanopsis carlesii cultivation [YCP] after slash‐and‐burn) since 2012. Stepwise power‐law regressions were used to identify the key variables and formulate the responses. Results show that the YCF and YCP following slash and burn have extremely high erosion rates, over 20 t ha−1 yr−1 (twofold higher than the global tolerable threshold), during the first year. In contrast, the erosion rate is only approximately 1.3 t ha−1 yr−1 in the ANR. The high erosion rates reveal the environmental vulnerability and the necessity of management in this region. Stepwise regressions suggest total rainfall rather than rainfall intensity as key variable probably because the forest canopy substantially offsets raindrop kinetics. The nonlinear runoff and erosion responses indicate that the risk of soil erosion is extremely high when vegetation cover is less than 40% and rainfall is greater than 80 mm. This study, therefore, suggests that windrowing harvest residues into strips or maintaining a vegetation cover greater than 40% is a sound management practice for mitigating land degradation in this region.
Geometric ergodicity of the multivariate COGARCH(1,1) process

ABSTRACT For the multivariate COGARCH(1,1) volatility process we show sufficient conditions for the existence of a unique stationary distribution, for the geometric ergodicity and for the finiteness of moments of the stationary distribution by a Foster-Lyapunov drift condition approach. The test functions used are naturally related to the geometry of the cone of positive semi-definite matrices and the drift condition is shown to be satisfied if the drift term of the defining stochastic differential equation is sufficiently ‘negative’. We show easily applicable sufficient conditions for the needed irreducibility and aperiodicity of the volatility process living in the cone of positive semi-definite matrices, if the driving Lévy process is a compound Poisson process.
A Royal Charter Is Not Enough – How PM Professional Associations Can Continually Show the Value of Professionalisation to the Markets

The Association for Project Management (APM) is engaged in the process of raising the status and performance of Project Management (PM) in the UK. They have obtained a royal charter, regarded as the “locus of professionalisation”, but can the APM really assist PM to achieve “a world where all projects succeed”, when there is no provable link between professionalisation and performance of practitioners? This current claim alone (along with chartership) will not improve the profession’s market reputation, which also raises concerns regarding the APM tactics for growth by engaging practitioners and corporate partners. This article uses actor-network theory to re-frame a historical case of the major UK Cost Accounting Association (ICWA), identifying the tactics this association used to effectively represent the value of the occupation/profession and influence their markets. Parallels and recommendations are generated for the APM, research directions are proposed for PM professionalisation and associations’ tactics for building market value.
Effect of Tensile Stress on the Passivity Breakdown and Repassivation of AISI 304 Stainless Steel: A Scanning Kelvin Probe and Scanning Electrochemical Microscopy Study

11 The interplay between mechanical stresses and electrochemical reactions may lead to stress 12 corrosion cracking or hydrogen embrittlement for many materials. In this work, the effect of 13 the tensile stress on the electrochemical properties of AISI 304 stainless steel was studied 14 using scanning Kelvin probe (SKP) in air and scanning electrochemical microscopy (SECM) 15 in an aqueous 0.5 M Na 2 SO 4 electrolyte. The measurements were performed under load- and 16 load-free conditions. 17 No influence of the elastic stress on the electrochemical potential of the steel was found. In 18 contrast, the plastic strain induces dislocations and dislocation pile-ups, which emerge to the 19 surface. The formation of new active surfaces is accompanied by an increase in the roughness 20 and a 150-200 mV decrease in the steel potential. After activation, the potential increased due 21 to passivation of the emerging surfaces by a newly grown oxide film, which took place under 22 both the load and load-free conditions and followed a time dependence of 𝞿 = A log t + B. 23 Formation and then passivation of the new surfaces increased and then decreased the 24 reduction current of the mediator in the SECM measurements. The effect of residual stress 25 stored in the steel due to the development of dislocations on the reactivity of the re-passivated 26 surface was investigated.
Hyperspectral Imbalanced Datasets Classification Using Filter-Based Forest Methods

A large variety of algorithms have been proposed for hyperspectral data classification in the literature. Among them, classical forest methods, such as bagged tree, random forest, oblique random forest, and rotation forest, have received much attention, thanks to their efficiency. Recently, two filter-based forest methods, called balanced filter-based forest (BFF) and cost-sensitive filter-based forest (CFF), have been proposed for high-dimensional data classification. These methods also have the solutions for imbalanced data problem. In this paper, these two methods were examined and compared with the classical forest methods for the classification of several well-known imbalanced hyperspectral datasets. The results indicated higher efficiency and reliability of the filter-based forests as compared to the classical forests. Moreover, they were smaller and sparser ensembles than the competitors. Furthermore, these two forests (especially BFF) were generally more successful for the classification of minority classes in hyperspectral datasets.
Hemogasometry, metabolic profile and acute-phase proteins in primiparous Holstein cows supplemented with butafosfana associated or not of cyanocobalamin

Abstract The aim of study was to evaluate whether butafosfan, associated or not with cyanocobalamin, alters the metabolic profile, hemogasometrics and acute phase proteins in recent postpartum dairy cows. Twenty-five cows (n = 25) were selected for study and divided into three groups: Butafosfan (BUT, n = 9); Butafosfan + Cyanocobalamin (BUTC, n = 9); and Control (CTL, n = 7). Treatments were applied daily from calving until 5 days postpartum. Blood samples for hemogasometry were performed on days 0, 1, 2 and 3, and for other metabolites on days 0, 1, 2, 3, 4, 5, 10, 15, 20 and 28 postpartum. Blood pH was lower in the BUT and BUTC groups than in the CTL group (p = .03) and carbon dioxide pressure was higher in the BUT and BUTC groups compared to CTL (p = .01). In addition, ionised calcium levels were higher in the BUT and BUTC groups (p = .0003) in comparison to CTL, whereas the BUT group had higher levels. The BUT group had the lowest levels of paraoxonase (p = .03). On the other hand, glucose levels tended to be highest in the BUT group (p = .08). The butafosfan with or without cyanocobalamin increased ionised calcium levels and tended to stabilise blood pH in the early post-partum cows, and butafosfan without cyanocobalamin tended to increase blood glucose levels. Highlights Treated animals increase serum ionised calcium; Treated animals have a reduction in blood pH; Butafosfan tends to increase the glucose concentration.
Moral Injury Among Professionals in K–12 Education

This article presents the quantitative portion of a mixed methods study of moral injury among professionals in K–12 public education. Using a cross-sectional correlational survey design, 218 licensed K–12 professionals from 68 schools in one urban school district in the Midwest completed an on-line survey that included measures of moral injury and emotional and behavioral correlates. The K–12 professionals exhibited levels of moral injury similar to those experienced by military veterans. Correlational analyses found that experiences of moral injury were associated with feelings of guilt, troubled conscience, burnout, and the intention to leave one’s job. Linear regression analyses demonstrated that professionals working in high-poverty, racially segregated schools were significantly more likely to endorse experiences of moral injury. These findings reinforce the significance of the intersectionality of race and class in reproducing oppressive and immoral educational practices and outcomes. A deeper understanding of and greater attention to potential sources of moral injury is critical in order to foster a more just and ethical education system.
Immediate Changes in Organic Matter and Plant Available Nutrients of Haplic Luvisol Soils Following Different Experimental Burning Intensities in Damak Forest, Hungary

One of the major pedological changes produced by wildfires is the drastic modification of forest soil systems properties. To our knowledge, large research gaps are currently present concerning the effect of such fires on forest Haplic Luvisols soils in Central Europe. In this study, the effects of experimental fires on soil organic matter and chemical properties at different burning intensities in a Central European forest were examined. The study was conducted at Damak Forest, in Hungary, ecosystem dominated by deciduous broadleaf trees, including the rare Hungarian oak Quercus frainetto Ten. The experimental fires were carried out in nine different plots on Haplic Luvisol soils transferred from Damak Forest to the burning site. Three types of fuel load were collected from the forest: litter layer, understorey and overstorey. Groups of three plots were burned at low (litter layer), medium intensity (litter and understorey) and high intensity (litter, understorey and overstorey). Pre-fire and post-fire soil samples were taken from each plot, analysed in the laboratory and statistically compared. Key plant nutrients of organic matter, carbon, potassium, calcium, magnesium and phosphorus were analysed from each sample. No significant differences in soil organic matter and carbon between pre- and post-fire samples were observed, but high intensity fires did increase soil pH significantly. Calcium, magnesium and phosphorus availability increased significantly at all fire intensity levels. Soil potassium levels significantly decreased (ca. 50%) for all intensity treatments, in contrast to most literature. Potassium is a key nutrient for ion transport in plants, and any loss of this nutrient from the soil could have significant effects on local agricultural production. Overall, our findings provide evidence that support the maintaining of the current Hungarian fire prevention policy.
Visualisierung von OSGi-basierten Softwarearchitekturen - Eine vergleichende Evaluation der Usability in 2D und Virtual Reality

Die Entwicklung komplexer Softwarearchitekturen bringt neben all dem technologischen Fortschritt auch viele Herausforderungen mit sich: Source Code wird immer umfangreicher und somit unubersichtlicher, was die schnelle Auffassung eines Softwareprojekts erschweren kann. Der Bereich der Softwarevisualisierung ermoglicht es, Source Code so darzustellen, dass die Komponenten und Abhangigkeiten eines Softwareprojekts schnell erfasst und verstanden werden konnen. In der vorliegenden Arbeit wurden zwei Softwarevisualisierungen in 2D und VR mit Hilfe einer Nutzerstudie verglichen und auf ihre Usability untersucht. Die Ergebnisse liefern Implikationen fur die weitere Entwicklung solcher Systeme.
It Takes Guts to Go Green: Identifying the Factors That Limit the Evolution of Herbivory in Reptiles Background

The evolution of herbivory in reptiles is rare and poorly understood. Researchers have speculated why some lineages of lizards have undergone evolutionary shifts from omnivory to herbivory, but no one has studied the mechanistic basis of this form of diet evolution. I will test whether induced shifts in diet (i.e., omnivory to herbivory) adhere to the popular paradigm that formfollows-function in evolution. This hypothesis predicts that major evolutionary changes occur in a predictable pattern: behavior evolving first (e.g., recognizing plants as food), followed by changes in physiology (e.g., gut enzyme activity), and finally morphology (e.g., gut size and proportion). To test this hypothesis on a proximate level, I will compare several physiological and morphological characteristics of the alimentary tracts of omnivorous lizards ( Pogona vitticeps) raised on one of three diets (carnivore, omnivore, or herbivore). The digestive tract is the focus of this investigation because, unlike other traits associated with specific diets (e.g., teeth), the gut exhibits both flexibility and plasticity in response to changes in diet, thus providing the necessary variation upon which selection could act. I will measure rates of growth, digestive efficiency, and passage rate as whole-organism measures of digestive performance. Gut enzyme levels and nutrient transport rates will provide measures of tissue-level function. Gross and histological measures of gut anatomy will quantify morphological plasticity. My study should elucidate whether physiological and/or morphological characteristics preclude this omnivore from exploiting a strictly herbivorous diet. This is the first study to attempt to elucidate the mechanisms constraining the evolution of herbivory from omnivory, while simultaneously testing the paradigm that major evolutionary shifts evolve in a form-follows-function manner.
Study on the Effects of Hierarchical Wavy Morphology on Clearance Flow

Clearances broadly exist in hydraulic components, such as the matching clearances of piston/cylinder, swash plate/slipper pad and cylinder block/valve plate, etc., in which most of the energy is dissipated by friction and leakage [1]. With the increasing demand for an environmentally friendly, non-flammable, readily available and hygienic fluid medium in hydraulic systems, water used as a pressure medium has caused renewed interest. However, the kinematic viscosities of water and mineral oil are 1 m2/s and 29 m2/s at room temperature at atmospheric pressure, respectively. Lower viscosity is accompanied by poorer lubricity and larger leakage. For certain matching clearances, the leakage rate of water is larger than that of oil, which will cause more internal and external leakages for water hydraulic systems [2]. Therefore, smaller clearances have to be considered in order to achieve reduced leakage. However, narrower gaps in water hydraulic components will cause mechanical wear [1] and [3] and fluid erosion [4] due to the poor lubrication of water, which will enlarge gaps, leading to more leakage [5]. Surface topography technology has emerged in recent years as an effective method to reduce energy dissipation [6] to [8]. Recent works on various forms and shapes of surface texturing for high efficiency [9] and [10], energy-saving [11] and [12] and long performance life [13] and [14] have been carried out, which has already succeeded in many industrial applications [8], [15] and [16], such as seals [17] and [18], bearings [19] and [20] and gears [21] and [22]. An attempt to optimize piston topography to minimize energy dissipation within the piston cylinder interface was made by Wondergem and Ivantysynova [23] and Ivantysynova [24], who proposed a barrel-like piston. Ivantysynova and Lasaar [25] demonstrated the potential of an advanced gap design using computer simulation. The load carrying ability, piston friction force and gap flow were computed for all investigated surface variations, and then an improved barrel-like piston was proposed to reduce energy dissipation generated by piston/cylinder assembly.

Incidence of some anaerobic bacteria isolated from chicken meat products with special reference to Clostridium perfringens

Anaerobic spore formers, especially Clostridium perfringens, represent one of the most prevalent bacterial food poisoning outbreaks which mostly related to consumption of contaminated meat and meat products, therefore, a total of 125 random raw and half cooked chicken meat samples represented by (breast, thigh, nuggets, panée and frankfurter “25 of each”) were collected from various retail stores and supermarkets in Qualyubia governorate. Results illustrated that, raw thigh samples were the most contaminated with anaerobic bacterial counts in incidence of 84%. The identified strains were C. perfringens, C. sporogenes, C. bifermenants, C. butyricum and C. sordelli in 21.6, 16, 8, 3.2 and 3.2%, respectively. Regarding to the incidence of vegetative and spore of C. perfringens were 24, 32, 20, 16, 16% and 16, 20, 16, 8, 8% in examined raw breast, raw thigh, nuggets, panée and frankfurter, respectively. 33.3% of isolates were lecithinase positive strains and typed as C. perfringens type A (6.4%), type D (0.8%); in absence of neither type B nor D. Experimental heat resistant C. perfringens spores were six heat resistant strains; where all isolates were of type A. The high incidence of these food poisoning microorganisms in chicken meat may indicate defects in sanitary conditions and handling in processing plant.
Treatment of Adult Patients with Relapsed/Refractory B-Cell Philadelphia-Negative Acute Lymphoblastic Leukemia

The majority of adult patients affected by B-cell acute lymphoblastic leukemia (B-ALL) will relapse after an initial response, while approximately 20% will display primary resistant disease. Patients suffering from relapsed/refractory B-ALL have a very poor outcome. Allogeneic hematopoietic cell transplantation (HCT) still represents the only curative approach, but is not so frequently feasible, because of patient's fitness, donor availability, and the ability to achieve a remission prior to HCT. The estimated remission rates with conventional cytotoxic agents are around 30%, but they are short-lived. These disappointing results led to the introduction of new immunologic-based treatments—blinatumomab and inotuzumab. They produced a substantial improvement in terms of response rates, with the ability, in most cases, to induce a minimal residual disease (MRD)-negative status. Similarly, T cells engineered to express a CD19-specific chimeric antigen receptor (CAR-T) have yielded sensational results among patients with relapsed/refractory B-ALL, with unexpectedly high MRD-negative complete remissions rates. However, the first studies looking at long-term outcomes after CAR-T infusions told us that a significant fraction of such responses are not durable, and may benefit from a consolidation approach such as an allogeneic HCT.
Genuine Triadicity in Computation, Cognition and Consciousness

Abstract Charles Peirce insisted that representation is a genuine three-part relation, irreducible to a complex of two-part relations. Demonstrations that two-part relations (like stimulus and response) can be described as three-part are chaff in the wind. Ironically, Peirce’s well-known description in semiotic language of sunflowers makes that error. Until recently, there was scant reason to speak of “sign” – in its full Peircean sense – in biology, computation, or even for unconscious thought. Current developments in computation and animal behavior suggest that triadic relations could be inherent in some classes of their operations, but this article does not find that possibility demonstrated. Instead, the argument is advanced that we should recognize a distinct theory of data (cybernetics) as adequate to describe the role of information in primitive lifeforms. Thus, we adopt definitions that do not support the proposal associated with (though not originating with) Thomas Sebeok, that life and semiosis are coextensive.
Feasibility Study of Hydration Monitoring Using Microwaves–Part 2: Measurements of Athletes

Hydration is a key consideration for athletes, where even mild levels of dehydration may negatively impact performance. Existing methods of assessment are either inaccurate or impractical for use in field settings, motivating the search for new approaches. Extremity microwave measurement is a promising method for ongoing hydration monitoring, owing to the inherent differences in dielectric properties with varying tissue water content. This paper reports on a feasibility study of in vivo hydration assessment using microwave measurements in athletes undergoing acute water loss during exercise. We developed and then tested a system for performing reliable microwave property estimation at the forearm. This system was used to measure hydration status in varsity wrestlers before and after a training session. A relationship between estimated permittivity and body weight change due to water loss was found, showing promise for the use of microwaves to assess hydration status. No significant relationship with attenuation was found. A novel method of assessing changes in hydration status is described, which may be of practical use for athletes in guiding fluid replacement during and after exercise.
Invariants of piecewise-linear 3-manifolds

In this paper we develop a theory for constructing an invariant of closed oriented 3-manifolds, given a certain type of Hopf algebra. Examples are given by a quantised enveloping algebra of a semisimple Lie algebra, or by a semisimple involutory Hopf algebra. The invariant is defined by a state sum model on a triangulation. In some cases, the invariant is the partition function of a topological quantum field theory.
