AbstractWe show that a nearly square independent and identically distributed random integral matrix is surjective over the integral lattice with very high probability. This answers a question by Koplewitz [6]. Our result extends to sparse matrices as well as to matrices of dependent entries.

This paper investigates costs and benefits associated with low-carbon economic development pathways realization to the mid XXI century. 30 scenarios covering practically all “visions of the future” were developed by several research groups based on scenario assumptions agreed upon in advance. It is shown that with a very high probability Russian energy-related GHG emissions will reach the peak before 2050, which will be at least 11% below the 1990 emission level. The height of the peak depends on portfolio of GHG emissions mitigation measures. Efforts to keep 2050 GHG emissions 25-30% below the 1990 level bring no GDP losses. GDP impact of deep GHG emission reduction - by 50% of the 1990 level - varies from plus 4% to minus 9%. Finally, very deep GHG emission reduction - by 80% - may bring GDP losses of over 10%.

Rational antibiotic therapy is one of the most important components in the treatment of children with various infectious and inflammatory diseases. However, wide and sometimes unjustified use of AB in pediatric practice often leads to the development of a variety of complications. Children receiveing AB, especially during the first 5 years of life, are at a very high risk of developing antibiotic-associated diarrhea (AAD) which manifests itself in three or more episodes of unformed stools for two or more consecutive days or for 8 weeks after withdrawal. The most relevant pathogen of AAD is C. difficile which, according to various data, causes from 10 to 25% of AAD cases and 90 to 100% of all cases of pseudomembranous colitis (PMC). Given the high probability of developing dangerous complications such as PMC, special attention should be paid to the prevention of the infection associated with C. difficile by reducing the frequency of uncontrolled and unjustified use of AB. A new generation of eco-antibiotics can be recommended which allow to maintain diversity of the intestinal microbiota and are less likely to cause complications.

The protection of wild animals from mutilation or being killed during haymaking is still a serious problem connected with high working speeds and widths of modern harvesting machines. That is why the main aim of this study was to test low-cost, high-speed and low-noise infrared array sensor Melexis MLX90621 for the application of wildlife detection with the potential to be used in front of the mower equipment. The tests with two different crops with or without a hidden dog were made. Results showed that the sensor is able to detect an animal hidden in the crop with very high probability. Nevertheless, direct sunlight conditions can cause the problems when using infrared technology. A simultaneous use of other sensors working on different principle than infrared technology can be thus recommended.

The rate of thromboembolic complications associated with thrombophilia is very high; therefore the detection of thrombophilia mutations in the high-risk group of patients is important for the prevention of morbidity, mortality and obstetric losses. The problem of thrombophilia is dealt with by doctors of various specialties: laboratory stuff, geneticists, vascular surgeons, hematologists, neurologists, cardiologists and obstetricians-gynecologists. At the same time, patients with spontaneous thrombosis are followed-up for years without proper examination for thrombophilia. Considering that pregnancy is a condition associated with a high probability of re-thrombosis, it is advisable to determine the cause and tactics of management and treatment of pregnant women as early as possible during the period of pregnancy.

A Project could be told success if it had a capability to fulfill a project’s goal, which was project could be done either in time or do not have a major lateness. Many things were affecting project buildings processing. This research purpose was to analyze whose causing lateness for apartment buildings project event in Surabaya. To analyze so many cause lateness event would be needed a systematic method approach. This research’s method was used a Fault Tree Analysis (FTA) Method which was used to seek cause event and the probability of lateness. Not only two of those methods, but also expert judgment technique was conducted by using questionnaire to seek probability and to analyze variable cause event. As a result of FTA method was obtained a very high probability of lateness with the main cause event was classified into 4 groups, were caused by owner, caused by supervising consultants, caused by contractor, and caused by environment circumstances. From four of those main causes was obtained some results, first of all from owner’s perspective were a lot of assignment alteration and late payment installment to contractor, second of all from supervising consultants’ perspective was a checklist survey result in certain area, the contractor’s work could not be continued because of such a certain things, third of all from contractor’s perspective was caused by inaccurate work method, and the last of all from environment circumstances was the local people felt so agitated because of the project location to close to them.

Effective project management techniques are critical to managers and decision makers in handling projects in today’s competitive environment. It is required that with such techniques, managers can carry out projects and complete them within specified time and resource constraint. This research considers the application of Program Evaluation and Review Technique (PERT). PERT was used to analyze data collected from Mega Star Technical and Construction Company in charge of the renovation/building construction of renovaworks at 48 Forces Avenue, Old GRA, Port Harcourt, Nigeria. The technique was used to obtain the network diagram, critical path, expected completion time for the project and the probability of completion within a required date. Ms Project version (2013) software was also used for the analyses. Results obtained revealed that the project can be completed within record time and possess a very high probability of completing the project within a stipulated date.

Abstract During the 24 hr following the great San Francisco, California, earthquake of 18 April 1906, separate seismic events were felt at Paisley, Oregon; Phoenix, Arizona; Los Angeles, California; and Brawley, California (MMIX). Using probability theory, we show that the occurrence of felt earthquakes in each of these widespread locations on the same day would constitute a rare event. Rates of felt-earthquake occurrences over a 9-yr period from 1897 to 1906 were determined for the four different regions that experienced earthquakes within 24 hr after the 1906 event. We modeled the likelihood of occurrence of these aftershocks in the spirit of the “ball-in-the-box” probability problem, and the results indicated a very high probability that the aftershock zone of the great earthquake extended at least 500 km beyond the extent of ground breakage, implying a disturbance of the stress field over an area at least two to three times longer than the fault break itself.

Globalization processes mean, among other things, the spread of trends that determine the socio-religious development of a region to other spatial areas. This does not happen with an inevitable necessity, it is not a ubiquitous feature of globalization, but it does happen with a very high probability. Moreover, when it comes to development within the same confessional systems. In this context, it is pertinent to note that some of the widespread forms of religious practices in Ukraine today, and moreover, religious structures, fifteen or twenty years ago, seemed to be exclusively Western. This is especially true of the large number of denominations, movements and movements that are Protestant in origin and are referred to as "evangelical" in English literature.

AbstractWe establish a relationship between decay centrality and two widely used measures of centrality, namely degree and closeness. We show that for low values of the decay parameter the nodes with maximum decay centrality also have maximum degree, whereas for high values of the decay parameter they also maximize closeness. For intermediate values, we provide sufficient conditions that allow the comparison of decay centrality of different nodes and we show via numerical simulations that in the vast majority of networks, the nodes with maximum decay centrality are characterized by a threshold on the decay parameter below which they belong to the set of nodes with maximum degree and above which they belong to the set of nodes with maximum closeness. We also propose a simple rule of thumb that ensures a nearly optimal choice with very high probability.
