Theoretical uncertainties on the extraction of in-medium NN cross sections by different Pauli blocking algorithms

Three typical Pauli blocking algorithms in quantum molecular dynamics type models are investigated in the nuclear matter, the nucleus, and heavy ion collisions. In nuclear matter, the blocking ratios obtained with the three algorithms are underestimated by 13%-25% compared to the corresponding analytical values. For a finite nucleus, spurious collisions occur around the surface of the nucleus owing to the defects of the Pauli blocking algorithms. In the simulations of heavy ion collisions, the uncertainty of stopping power arising from the different Pauli blocking algorithms is less than 5%. Furthermore, the in-medium effects of nucleon-nucleon (NN) cross sections on the nuclear stopping power are discussed. Our results show that the transport model calculations with free NN cross sections result in the stopping power decreasing with beam energy when the beam energy is less than 300 MeV/u. To increase or decrease the values of the stopping power, the transport model calculations need enhanced or suppressed model dependent in-medium NN cross sections that are expected to be smaller than the true in-medium NN cross sections.
Evaluation of Stop Bar Video Detection Accuracy at Signalized Intersections

Many agencies nationwide have adopted video vehicle detection technology as an alternative to inductive loops. While many product evaluations have been performed, the majority of these evaluations have concentrated on freeway applications where speed and volume were the primary evaluation criteria. At an actuated intersection, the metrics of speed and volume do not necessarily represent how well a device will operate as a presence detector. Video detection was evaluated at two signalized intersections in West Lafayette, Indiana and Noblesville, Indiana. A camera on each approach was located at the vendor recommended position, at a height of 40 feet and offset so that the camera was approximately inline with the lane line dividing the left-turn lane and through lane. Two additional cameras were located on each approach at less optimal horizontal and vertical locations. Additionally at the West Lafayette site, a fourth camera was located directly above the stop bar so that it looked down onto the detection zone. Inductive loops were used as baseline data to screen for discrepancies. Each time the loop detectors were not in agreement with a specific video detector, a discrepancy was noted. A digital video recording was later observed to determine whether the video detector or the loop detector was in error. An analysis of the data showed video detection was found to produce statistically significantly more false detections and missed detections than the loop detectors on most phases. Generally, only very small variations in video detector performance were observed at the different camera locations. The video detection was also evaluated in terms of its’ consistency of detector turn-on and turn-off times. The video detection displays an undesirable inconsistency between night periods and day periods where it tends to activate 1 to 3 seconds earlier during the night period due to headlight reflections on the pavement. However, the camera at West Lafayette located directly above the stop bar displayed very consistent behavior between the night and day periods.
Predictive pre-cooling of thermo-active building systems with low-lift chillers

This article describes the development and experimental validation of a data-driven model predictive control algorithm that optimizes the operation of a low-lift chiller, a variable-capacity chiller run at low pressure ratios, serving a single zone with a thermo-active building system. The predictive control algorithm incorporates new elements lacking in previous chiller pre-cooling control optimization methods, including a model of temperature and load-dependent chiller performance extending to low-pressure and part-load ratios and a data-driven zone temperature response model that accounts for the transient thermal response of a concrete-core radiant floor thermo-active building system. Data-driven models of zone and concrete-core thermal response are identified from monitored zone temperature and thermal load data and combined with an empirical model of a low-lift chiller to implement model predictive control. The energy consumption of the cooling system, including the chiller compressor, condenser fan, and chilled-water pump energy, is minimized over a 24-h look-ahead moving horizon using the thermo-active building system for thermal storage and radiant distribution. A generalized pattern-search optimization over compressor speed is performed to identify optimal chiller control schedules at every hour, thereby accomplishing load shifting, efficient part-load operation, and cooling energy savings. Results from testing the system's sensible cooling efficiency in an experimental test chamber subject to the typical summer week of two climates, Atlanta, GA, and Phoenix, AZ, show sensible cooling energy savings of 25% and 19%, respectively, relative to a high efficiency, variable-speed split-system air conditioner.
Hepatoprotective and Haematoprotective Roles of Gongronema latifolium Benth Aqueous Extract in Alloxan-Induced Diabetic Rats

This research evaluates the hepatoprotective and haematoprotective abilities of the extract of Gongronema latifolium leaves in diabetic rats. Forty animals were induced intraperitoneal using alloxan of 150 mg/kg body weight. The Wistar rats were thereafter divided as follows: normal control, diabetic untreated control, diabetic rats received 5 mg/kg body weight of metformin, and diabetic rats received three ethnobotanical doses (6.36, 12.72, and 25.44 mg/kg body weight) of aqueous extract of G. latifolium leaves (AEGLL). On the 14th day of the experiment, the rats were relinquished, and various hepatoprotective and haematoprotective biomarkers were assessed. Diabetic rats administered AGELL demonstrated normoglycaemia, reduced inflammatory levels as well as activities of transaminases. Also, diabetic animals that received AGELL show a substantial increase in protein, albumin, and hematological parameters determined when linked to diabetic control rats. Hence, three ethnobotanical doses revealed the hepatoprotective and haematoprotective nature of this plant.

Interference Management and Exploitation in Emerging Wireless Networks

In the past decade, with the prevalence of smart phones, the m ain use of cellphones has been shifted from phone call to multimedia access. This paradigm shift has resulted in the demand for higher and higher transmission rate. Many sophisticated ph ysical layer techniques, such as IDMA (interleave division multiple access), OFDM (orthogonal d ivision multiple access), MIMO (multiple input multiple output), IA (interference alignment) an d massive MIMO) have been proposed to cater for this demand. Meanwhile, cognitive radio networks and femtocell networks are proposed to strengthen the cellular networks. Given these new exciting techniques, how to incorporate the m into current wireless networks is one of the main issues need to be addressed. Moreover, taki ng close look at these techniques, how to manage interference so that the throughput can be enha nced is one of the most important problems. The first part of this dissertation investigates how to incor porate IDMA into two-tier femtocell networks so that the throughput of femtocell networks can be enhanced. Based on the computational capability of the femtocells, three schemes are prop osed for the femtocell networks. The second part of this dissertation addresses the problem o f incorporating interference alignment to OFDM and MIMO-OFDM system. We firstly prove the upper b ound of the throughput with an integer programming formulation. Then considering practical constraints of the (MIMO) OFDM system, effective algorithms are proposed to approach the theoretical bounds. In the third part of this dissertation, how will the primary u ser and secondary users equipped with multiple antennas behave in cognitive radio networks i s studied. With a Stackelberg game formulation, we derive the unique Stackelberg game equilibriu m for the primary user and secondary users. The proposed scheme is also shown to outperform the no n-spectrum-leasing scheme and a cooperative scheme in the literature.
Organizational theory

Objective. Analysis of the family resilience as its systemic characteristics from the standpoint of the organizational theory of A.A. Bogdanov. Background. The growing uncertainty of the existence of a person and a family makes such a quality as resilience in demand. The approach to the family as a system and practical work with it from the perspective of studying its resilience presupposes an emphasis not on the weakness and dysfunctionality of the family, but on those potential and real possibilities that are inherent in it. The family resilience as its systemic characteristic, depends on the balance of risk and protective factors, in the quality of which the family’s resources are considered. Family resourses are indicators of the family resilience. The resources of the nuclear family, contributing to the formation and maintenance of its resilience in wide temporal, social and cultural contexts, are gradually uniting individual resources. The process of forming the resource capacity of the family is not only their accumulation, but also the synthesis and grouping of the resources of the whole family as a system. Methodology. Organizational theory A.A. Bogdanov. Conclusions . Organizational theory A.A. Bogdanova, being a general scientific approach to the study of any system, makes it possible to analyze the family resilience as its systemic characteristics from the standpoint of the interaction of multidirectional activities mediated by differences in the understanding of family values, communication needs and organizational patterns. The joint coordinated activity of family members, leading to an increase in family resilience, is achieved with the help of certain resources.
Using wikis to help first year students develop collaborative knowledge management skills for tomorrow

In the information economy the ability to harness digital technologies to capture and manage knowledge is a critical skill for university graduates. This study examines the use of wikis as an assessment tool to help first year students develop a range of knowledge management skills, including creative collaboration, consensus building and technical literacy. The purpose of the study is to provide an exploratory analysis of student attitudes toward the use of wikis as a collaborative assessment task. The results indicate that most students perceived wikis to be a flexible, convenient and fair pedagogical technique for collaborative learning. While many students preferred the wiki to a paper-based assessment, some students were not convinced that the task produced better collaborative outcomes. It is suggested that a staged wiki assessment might overcome some of the perceived shortcomings reported by students.
Determinants of Rural Poverty in Southern Ethiopia: Empirical Evidence from Gedeo Zone

Poverty especially in the rural areas has turned out to be a great global social and economic challenge in this 21 st century. Poverty is a complex, interlocked and multidimensional phenomenon. It is lack and deprivations of decent life sustaining resources that people experiences at various degrees so as different life chances. This study was carried out in southern Ethiopia with empirical evidence from Gedeo zone. The specific objective of the study was to investigate determinants of rural poverty. In order to achieve its objective, the study made use of the primary data collected through survey and interview using semi structured questionnaire. The study employed a multi-stage sampling procedure for sample selection. Employing cross sectional design, the research was undertaken on a random sample of 325 households in the study area. An absolute poverty line set in the study area using CBN approach; based on food basket of 2200 Kcal per adult per day was used to identify the poor from non-poor households. Accordingly, the absolute poverty line of Birr 4463.35 was used in the study area. The binary logistic regression model was employed so as to investigate determinants of rural poverty in the study area. The model output revealed that the number of livestock holding, land size , number of chicken owned, beehives ownership, Annual Income per Adult Equivalent, use of modern agricultural inputs , involvement in non-farm activities and saving habit of households were variables found with negative impact and significant determinants of poverty. Whereas, the variables with positive impact on household poverty and found to be significant were family size, age of household head and dependency ratio. Therefore, alleviation of rural poverty in the study area in particular and rural Ethiopia in general requires policy formulation and adoption of strategies with respect to those variables found to have a significant effect on poverty status of rural households.
Performance Report on Jointed Concrete Pavement Repair Strategies in Texas

Project 0-4517 was established to summarize the results from the Lufkin experiment on US 59 and to develop statewide guidelines on how to select rehabilitation strategies for jointed concrete pavements (JCPs). This year 1 report reviews the performance of the six experimental sections on US 59 and makes recommendations for statewide implementation. The best performing section in Lufkin was the flexible base overlay, which involved placing high-quality crushed limestone directly over the JCP followed by an underseal and thin asphalt overlay. This was also one of the least expensive treatments used in the experiment. The large stone mix also gave good performance, but the crack and seat and full-depth repair techniques did not perform well. A forensic investigation was conducted to attempt to explain the variation in treatment performance. To complement the Lufkin results, a review is also presented of the performance of other JCP rehabilitation techniques recently evaluated by Texas Department of Transportation districts. An evaluation of crack retarding asphalt layers [Strata (Registered trademark)], grid layers [GlasGrid (Registered trademark)] and slab fracturing techniques is also included in the report.
Film thickness in elastohydrodynamically lubricated slender elliptic contacts: Part I – numerical studies of central film thickness

In this paper, analytical equations for the central film thickness in slender elliptic contacts are investigated. A comparison of state-of-the-art formulas with simulation results of a multilevel elastohydrodynamic lubrication solver is conducted and shows considerable deviation. Therefore, a new film thickness formula for slender elliptic contacts with variable ellipticity is derived. It incorporates asymptotic solutions, which results in validity over a large parameter domain. It captures the behaviour of increasing film thickness with increasing load for specific very slender contacts. The new formula proves to be significantly more accurate than current equations. Experimental studies and discussions on minimum film thickness will be presented in a subsequent publication.
Study of ischemia-modified albumin as a biomarker in critically ill patients with sepsis

Background: Critical ill will be accessed by sequential organ failure assessment (SOFA) and acute physiology and chronic health evaluation. Circulating ischemia-modified albumin is generated under ischemic and oxidative conditions and it reflects the disease severity. Aims and Objectives: The objective of this study is to compare the sensitivity and rapidness of Ischemia Modified Albumin as a biomarker with that of an already established biomarker, C-Reactive Protein in patients identified as critically ill septic patients. Materials and Method: A group of 30 subjects were identified using qSOFA as patients suffering from sepsis and their blood samples were taken. These samples were tested for ischemia modified albumin, an inflammatory biomarker, and each sample was also assessed for CRP. Similarly, control patients were assessed for IMA and CRP as well. Results: The results showed that IMA and CRP were both significantly elevated in sepsis, with mean values of 103.77 ± 15.61 ABSU for IMA and 35.58 ± 19.82 mg/L for CRP. However, it was found that the test performed for serum IMA is a quicker and more cost-effective test than that of CRP. Conclusion: This methodology will lead to the usage of a cheaper and more effective diagnostic and prognostic tool for patients succumbed to sepsis.
Uncertainty Quantification for Mechanical Properties of Polyethylene Based on Fully Atomistic Model

This study is to assess the effect of temperature and strain rate on the mechanical properties of amorphous polyethylene (PE) based on fully atomistic model. A stochastic constitutive model using data obtained from molecular dynamics (MD) simulations for the material is constructed. Subsequently, a global sensitivity analysis approach is then employed to predict the essential parameters of the mechanical model. The sensitivity indices show that the key parameter affecting Young’s modulus and yield stress is the temperature followed by the strain rate.

Context Reinstatement

Context reinstatement is the process by which we incorporate thoughts from our past into our current mental state. This chapter is concerned with characterizing the cognitive and neuropsychological underpinnings of context reinstatement. Modern theories of context reinstatement are inextricably tied to theories of how we process and perceive the present. The primary goal of this chapter is to present a conceptual framework for characterizing how experiences unfold in time, and how our mental states at each moment relate to our experiences. This framework allows us to compare, contrast, and test different theories of context reinstatement. A second component of this chapter is concerned with two fundamental properties of how our experiences unfold, and how we perceive and remember them: scale invariance and event segmentation. The chapter concludes with a reflection on the proposed role of context reinstatement in facilitating a range of important memory-related cognitive functions.
Design and Effectiveness of Modeling‐Based Mathematics in a Summer Bridge Program

Since students' success in their first‐semester college mathematics course is a key factor in their success in engineering, many summer bridge programs for underrepresented students focus on their preparation in mathematics. However, research on the design and efficacy of such programs is limited. We examine the design and effectiveness of a modeling‐based approach to mathematics for entering freshmen engineering students.
Perceived morality of direct versus indirect harm: Replications of the preference for indirect harm effect

Royzman and Baron (2002) demonstrated that people prefer indirect harm to direct harm: they judge actions that produce harm as a by-product to be more moral than actions that produce harm directly. In two preregistered studies, we successfully replicated Study 2 of Royzman and Baron (2002) with a Hong Kong student sample (N = 46) and an online American Mechanical Turk sample (N = 314). We found consistent evidential support for the preference for indirect harm phenomenon (d = 0.46 [0.26, 0.65] to 0.47 [0.18, 0.75]), weaker than effects reported in the original findings of the target article (d = 0.70 [0.40, 0.99]). We also successfully replicated findings regarding reasons underlying a preference for indirect harm (directness, intent, omission, probability of harm, and appearance of harm).

Knowledge Structures of Prospectors, Analyzers, and Defenders: Content, Structure, Stability, and Performance

The managerial cognition perspective argues that managers operating in complex, dynamic environments develop knowledge structures that help them focus their attention, interpretation, and actions. We explore the content and structure of top managers' strategic knowledge structures by measuring differences in the level of attention they give in annual reports to strategic issues and themes that Miles and Snow used to describe their main strategic types. Twenty-one themes that form seven main factors describing managers' strategic cognition are identified, and these demonstrate reasonable fit with the Miles and Snow model. We show that expert raters can recognize these factors when they read annual reports that contain them. Cluster analysis is then used to identify groups of firms that share similar profiles on these strategic dimensions which are interpreted as examples of cognitive strategic groups. These groups show alignment with Miles and Snow's strategic types, are relatively stable over time, and differ in financial performance. The sample comprises 1,038 listed Australian firms between the years 1992 and 2003.
