Theory and practice of non-intrusive active network measurements

Today's data networks are highly distributed and enormous in scale. The ability to measure them is vital to both network operators and end-users. Network measurement methods can broadly be classified into passive methods that rely on data collected at routers, and active methods based on observations of actively-injected probe packets. Active measurements, the focus of this dissertation, are attractive to end-users who, under the current network architecture, cannot access any measurement data collected at routers. Network operators use active measurements because they are easy to conduct, have low overhead and, in contrast to passive data collection methods, measure exactly what normal data packets experience. The most significant disadvantage of active measurements is the limited accuracy that has typically been achievable using them. One of the main reasons for this is in the need to be non-intrusive, thus leaving the measured systems uninfluenced by the observation, fundamentally affecting accuracy. In this dissertation, we use rigorous theoretical analysis to understand the impact of non-intrusiveness on active measurements and investigate how this theory translates into practice. Our investigation consists of three parts. In the first, we investigate sampling-related issues, i.e., when do we send probe packets and why? Our starting point is conventional wisdom that says that the "Poisson Arrivals See Time Averages (PASTA)" principle implies the need to use Poisson probing. We show that PASTA does not imply that Poisson probing is optimal because it ignores bias caused by probing intrusiveness and estimation variance. Using rigorous theory and simulations, we motivate rare probing, preferably at so-called mixing epochs, as a sound practical strategy. In the second part, we investigate if observed delays of (non-intrusive) probe pairs can be used to estimate cross-traffic properties in the single-hop case. Our starting point is the inability of prior works [SKK03] to estimate cross-traffic without hard-to-achieve timing control. We derive what can be estimated, in theory, and show that, under a well-motivated assumption, non-intrusive probe pairs can be used to estimate the entire distribution of cross-traffic in an intra-pair interval. Our third part is motivated by the apparent difficulty in designing non-intrusive active measurements robust to multi-hop queueing effects; We experience this first-hand with our single-hop cross-traffic estimators. We show that novel hop-dependent priority queueing primitives can be used to design Measurement-Friendly Networks (MFNs), networks in which accurate non-intrusive measurements, which are robust to multi-hop queueing effects, can be performed. Our primitives not only simplify network management tasks for network operators but are also easily deployable. In exploring MFNs, we find that nonpreemption and cross-traffic persistence cause unavoidable inaccuracies that represent, in a sense, fundamental limitations of active measurements.
Vibration‐based damage detection in a wind turbine using 1 year of data

In the current state of development, it is very hard to remotely evaluate the actual condition of wind turbines structures. This makes it impossible for a wind farm owner to correctly deliberate about the need of retrofitting the current wind turbine structure, as well as to decide about the possible extension of its operating lifetime. Taking into account this problem, this paper introduces the main aspects in the development of a vibration‐based monitoring system for an onshore 2.0‐MW wind turbine based on the identification of the modal properties of the most important vibration modes. Initially, the wind turbine is introduced, as well as the implemented monitoring system. Then, the main steps of the monitoring system are briefly described. A detailed attention is given to the statistical procedure based on regression models used to minimize the influence of operational and environmental effects over the features used to detect structural changes in the wind turbine. Lastly, the suitability of the system to detect damages is thus assessed, through the analysis of three common damage scenarios: onshore foundation damage; damage by scour on an offshore foundation; and blade damage. It is concluded that the system is capable of detecting damage in onshore and offshore foundations, as well as in rotor blades. The most important contribution of the paper is the definition of monitoring framework for damage detection, its implementation, and validation with monitoring data collected during more than 1 year in a utility‐scale wind turbine.
Climate variability impacts on agricultural output in East Africa

Abstract This paper investigates whether the effects of weather variability in temperature and precipitation on agricultural output are short- or long-run. The contribution of this paper is twofold. First, the paper attempts to establish whether temperature or precipitation variability affects agricultural output in the short or the long run. Second, it examined whether the effects of temperature or precipitation variability on agricultural output are homogenous across East African countries. The results reveal that variability in temperature had a long-run impact on agricultural output, while variability in precipitation had a short-run effect. The findings also reveal that the long-run temperature variability effect was heterogeneous across East African countries, and to some extent, there is also evidence for the long-run effect of precipitation variability. These results are crucial in providing decision-makers and other interested parties a thorough evaluation of climate impacts and adaptation measures aimed at increasing agricultural production and food security.
CHANGES IN CHEMICAL AND NUTRITIONAL QUALITY DURING COLD STORAGE OF SOME FRUIT AND VEGETABLE JUICE BLENDS.

Fresh juice blends are a popular food daily consumed by all people with different age and standard living for their low prices and pleasant flavor. In spite of the cheap price of these juices; they have high nutritive value for their high content of β-carotene, minerals as calcium, potassium, magnesium and iron. So, the main target of such manuscript was to follow up main components changes in untraditional fruit and vegetable juice blends during cold storage (5-7°C) for three months. Obtained results showed that, the moisture, total sugar, non-reducing sugar, β-carotene, total soluble solids contents and pH value of fruit and vegetable juice blends decreased while, total solids, reducing sugar contents and total bacterial counts increased after three months of cold storage. Juice blend No.(4) (50% apricot + 50% carrot) had the highest value of β-carotene (1000 μg/100ml). Finally, it could be concluded that fruit and vegetable juice blends under study were acceptable and in a good agreement with their Egyptian standard specifications as well as the high content of β-carotene.
Nanosecond pulsed electric field ablates rabbit VX2 liver tumors in a non-thermal manner versus radiofrequency ablation

Background Liver tumor remains an important cause of cancer-related death. Nanosecond pulsed electric fields (nsPEFs) are advantageous in the treatment of melanoma and pancreatic cancer, but their therapeutic application on liver tumors need to be further studied. Methods Hep3B cells were treated with nsPEFs. The biological behaviors of cells were detected by Cell Counting Kit-8, 5-ethynyl-20-deoxyuridine, and transmission electron microscopy (TEM) assays. In vivo, rabbit VX2 liver tumor models were ablated by ultrasound-guided nsPEFs and radiofrequency ablation (RFA). Contrast-enhanced ultrasound (CEUS) was used to evaluate the ablation effect. HE staining and Masson staining were used to evaluate the tissue morphology after ablation. Immunohistochemistry was performed to determine the expression of Ki67, proliferating cell nuclear antigen, and α-smooth muscle actin at different time points after ablation. Results The cell viability of Hep3B cells was continuously lower than that of the control group within 3 days after pulse treatment. The proliferation of Hep3B cells was significantly affected by nsPEFs. TEM showed that Hep3B cells underwent significant morphological changes after pulse treatment. In vivo, CEUS imaging showed that nsPEFs could completely ablate model rabbit VX2 liver tumors. After nsPEFs ablation, the area of tumor fibrosis and the expression of Ki67, proliferating cell nuclear antigen, and α-smooth muscle actin were decreased. However, after RFA, rabbit VX2 liver tumor tissue showed complete necrosis, but the expression of PCNA and α-smooth muscle actin did not decrease compared to the tumor group. Conclusions nsPEFs can induce Hep3B cells apoptosis and ablate rabbit VX2 liver tumors in a non-thermal manner versus RFA. The ultrasound contrast agent can monitor immediate effect of nsPEF ablation. This study provides a basis for the clinical study of nsPEFs ablation of liver cancer.
Higher Education In Paulo Freire's Critical Pedagogy: Commitment To Democratic Social Morality

This article aims to investigatethe issue of higher education in Paulo Freire's critical pedagogy.This pedagogy harshly criticizes the traditional professional function that characterizes the mission of higher education institutions and sees them as a major arena for professional training that realizes the economic interests of the hegemonic group.In addition, these institutions have become an instrument for training potential employees to pursue purely economic interests, thus becoming a major tool that serves, in great loyalty, the capitalist agenda.Against this reality, Freire'scritical pedagogy sees academic education as a kind of humanist mission and emphasizes that higher education institutions are committed to a democratic social morality that allows the learning community not only to understand the social reality and human social dilemmas that exist in society alone,but to become critical and social activists and work for the realization of a comprehensive social transformation.Therefore, the purpose of this article is to examine the alternative that this pedagogy poses for creating a new moral and humanistic space that strives to shape a more reformed and democratic society.
Nurse Job Satisfaction in the Midst of a Pandemic

Registered nurses (RNs) are crucial in the delivery of safe, high quality, accessible, and cost-effective care in the US health care system (Snavely, 2016). Strategies and intervention for nursing recruitment and retention are critical needs at the hospital unit management level especially during this time of coronavirus disease of 2019 (COVID-19) pandemic. Job satisfaction is a critical issue in healthcare as it has been associated with turnover and quality of nursing care. Research Question: What are the unit-levels of nurse job satisfaction among eight satisfaction dimensions (i.e., satisfaction with extrinsic rewards, scheduling, family/work balance, co-workers, interaction, professional opportunities, praise/recognition, and control/responsibility) in an acute medical-surgical unit? Objectives The objective of this project is to systematically obtain unit-level input to explore nurses’ views and experiences as it relates to job satisfaction. Methodology: This is a descriptive cross-sectional convenience study measuring job satisfaction among Registered Nurses in general acute medical-surgical units in a general acute care hospital in the Southwestern United States. This study is based on the analysis and synthesis of survey data using the McCloskey/Mueller Satisfaction Scale (MMSS) instrument at the unit-level which was designed to assess the satisfaction of hospital staff nurses (Mueller & McCloskey, 1990). The scale has 31 items capturing eight dimensions of satisfaction: satisfaction with extrinsic rewards (e.g., salary), scheduling (e.g., hours that they work), family/work balance (e.g., child care facilities), co-workers (e.g., their nursing peers), interaction (e.g., opportunities for social contact at work), professional opportunities (e.g., opportunities to belong to department and institutional committees), praise/recognition (e.g., recognition for their work from superiors), and control/responsibility (e.g., their participation in organizational decision making). Each item is rated on a five-point Likert scale. This study on nurse job satisfaction at the unit-level reduces gaps from many evidencebased studies on nurse outcomes using data from large national data bases. This unit level study provides focused data on one specific type of unit, acute medical-surgical units; because the study is focused on this one specific type of unit interventions it can be tailored to these specific units rather than a general hospital wide study resulting in hospital wide interventions. Intervention: Report of overall and individual unit results were provided to the nursing staff and management of the hospital. Ideas for potential interventions and recommendations on identified areas of greatest concern were solicited from them via zoom conference and/or in writing. Having the results, literature review was done to search for past interventions for specific identified areas with low satisfaction results.

: Background: Fagara zanthoxyloides is a medicinal plant used in traditional medicine for the treatment of elephantiasis, toothache, sexual impotence, malaria, dysmenorrheal and abdominal pain among rural dwellers. Objective: To study the In vitro anti-inflammatory and antioxidant activities of methanol extract of Fagara zanthoxyloides leaves. Materials and Methods: Methanol extract of Fagara zanthoxyloides leaves were used for this study. In vitro anti-inflammatory studies were performed for the extract using proteinase inhibition activity and albumin denaturation inhibition assays, while antioxidant activities were performed by determination of DPPH (1, 1-diphenyl-2-picrylhydrazyl) scavenging assay and hydrogen peroxide scavenging activity. Aspirin was used as a standard drug for the anti-inflammatory activity while vitamin C and E were used as standard drugs for the determinationof DPPH scavenging assay and hydrogen peroxide scavenging activity respectively. Results: At the concentration of 75 and 100 µg/ml, the methanol extract of Fagara zanthoxyloides showed significant (p &lt; 0.05) inhibition of 39 and 44% of proteinase inhibitory action and, 42 and 63% of albumin denaturation inhibition activity. In addition, the extract had effective DPPH radical scavenging and hydrogen peroxide scavenging activities. At a concentration of 80 µg/ml, the extract showed an inhibition of 53 and 77% of DPPH radical scavenging and hydrogen peroxide scavenging activities respectively. Conclusion: The present study showed In vitro antioxidant and anti-inflammatory activities of the methanol extract of Fagara zanthoxyloides which scientifically prove the ethnomedicinal claims. showed that the extract could be an effective antioxidant from the DPPH and hydrogen peroxide scavenging activities models. The 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity study shows that the methanol extract
Serendipitous Improvement of Schizophrenia after Stem Cell Transplant for Hodgkin’s Lymphoma

21-year-old male patient with schizophrenia diagnosed at age 15 with a history of poor response to olanzapine and risperidone. He referred auditory hallucinations with a pejorative content about himself. He was very suspicious and socially with drawn, to the extent of dropping out of high school and being unable to leave his home. One year afterward he was diagnosed with Hodgkin’s Lymphoma (HL). He underwent different chemotherapeutic schemes and three Stem Cell Transplants (SCT). Between the second and the third SCT, the patient received therapeutic doses of quetiapine (Positive and Negative Syndrome Scale [PANSS]: 147). In a period of 8 months, after the second SCT, patient’s PANSS dropped 60 points, his hallucinations decreased 90%, and he improved his negative, cognitive, and social symptoms, which allowed him to gradually reincorporate to his usual social and academic life. Currently, Hematopoietic Stem Cells (HSC) have been proposed as an alternative therapy for many chronic and incurable non-hematologic diseases. In psychiatry, the theory is that these HSC migrate to areas of inflammation in the brain via chemotaxis, and, through immunomodulation and secretion of bioactive molecules enhance neurogenesis, angiogenesis, and remodeling of axonal circuits. Studies on schizophrenic patients have confirmed both, that it is an inflammatory condition (cytokines and interleukins are elevated when compared to controls) and, that the brain is underdeveloped due to deficient neurogenesis; supporting. why HSC assisted in the marked clinical improvement observed in this patient, which would otherwise could not be explained by the natural history of the disease or therapeutic measures alone.
Privacy-Preserving Naive Bayesian Classification Over Vertically Privacy-Preserving Naive Bayesian Classification Over Vertically Partitioned Data Partitioned Data

: Protection of privacy is a critical problem in data mining. Preserving data privacy in distributed data mining is even more challenging. In this paper, we consider the problem of privacy-preserving naive Bayesian classiﬁcation over vertically partitioned data. The problem is one of important issues in privacy-preserving distributed data mining. Our approach is based on homomorphic encryption. The scheme is very eﬃcient in the term of computation and communication cost.
Music Stimuli Recognition in Electroencephalogram Signal

When humans are listening to music they perceive beats, rhythms and melodies. Music stimuli induce motor system activities and it has a powerful emotion trigger effect. Since music is a potential stimulus in electroencephalogram based emotion research we supposed that different kinds of songs are recognizable from electroencephalogram signal. In this study we try to recognize music-induced electroencephalogram responses with the popular Neurosky Mindwave device. This paper describes the test conditions and the efficiency of an artificial neural network in combination with different data pre-processing techniques. The final outcomes show the negative effect of frequency decomposition and that the meditation level has more significant effect on the recognition than a particular song.

Activityby Specific Inhibition of Myeloperoxidase hLF1-11 Exerts Immunomodulatory Effects The Human Lactoferrin-Derived Peptide

Because of their ability to eliminate pathogens and to modulate various host immune responses, antimicrobial peptides are considered as candidate agents toﬁght infections by (antibiotic-resistant) pathogens. We recently reported that hLF1-11 (GRRRRSVQWCA), an antimicrobial peptide derived from the N terminus of human lactoferrin, displays diverse modulatory activities on monocytes, thereby enhancing their actions in innate immune responses. The aim of this study was to identify the cellular target of hLF1-11 that mediates these effects. Results revealed that hLF1-11 binds and subsequently penetrates human monocytes, after which it inhibits the enzymatic activities of myeloperoxidase (MPO). Moreover, a chemical inhibitor of MPO (aminobenzoic acid hydrazide) mimicked the effects of hLF1-11 on the inﬂammatory response by monocytes and on monocyte–macrophage differentiation. Computer-assisted molecular modeling predicted that hLF1-11 can bind to the edge of and within the crevice of the active site of MPO. Experiments with a set of hLF1-11 peptides with amino acid substitutions identiﬁed the stretch of arginines and the cysteine at position 10 as pivotal in these immunomodulatory properties of hLF1-11. We conclude that hLF1-11 may exert its modulatory effects on human monocytes by speciﬁc inhibition of MPO activity. The Journal of Immunology , 2012, 188: 000–000.
Evaluation of Antidiabetic Effect of Ethanolic Leaves Extract of Becium grandi ﬂ orum Lam. (Lamiaceae) in Streptozotocin-Induced Diabetic Mice Diabetes, Metabolic Syndrome and Obesity: Targets and Therapy

Background: Becium grandi ﬂ orum has been used traditionally for treatment of different ailments including diabetes mellitus although it lacks scienti ﬁ c evidence. Thus, the present study was aimed at evaluating the antidiabetic effect of Becium grandi ﬂ orum in streptozotocin (STZ)-induced diabetic mice. Methods: The antidiabetic activity of hydro-ethanolic (30:70) leaf extract of Becium grandi ﬂ orum was evaluated in STZ (45 mg/kg)-induced diabetic and normal mice. Antihyperglycemic, hypoglycemic, oral glucose tolerance and body weight change effects of the extract were assessed after administering three doses of the extract (200, 400 and 600 mg/kg), glibenclamide 5 mg/kg (reference drug) and 2% Tween 80 (vehicle). One-way analysis of variance and Tukey ’ s post hoc test were used for data analysis. Results: All doses of the extract (200 mg/kg ( p <0.05), 400 mg/kg ( p <0.05) and 600 mg/kg ( p <0.01)) and glibenclamide 5 mg/kg ( p <0.001) showed statistically signi ﬁ cant blood glucose level reduction in normal mice as compared to Tween 80. The hydroalcoholic extract at a dose of 200 mg/kg ( p <0.05), 400 mg/kg ( p <0.01) and 600 mg/kg ( p <0.001) showed better blood glucose tolerance after 60, 120 and 180-minute treatment duration in normal mice as compared to negative control. In diabetic mice, Becium grandi ﬂ orum doses and the reference drug caused maximum reduction in blood glucose level at the end of the 15th day of treatment by 17.61%, 22.52%, 24.62% and 34.12%, respectively. The extract ’ s doses and the standard drug showed signi ﬁ cant ( p <0.05) improvement in body weight while the diabetic control continued to lose their body weight. Conclusion: Thus, Becium grandi ﬂ orum exhibits antihyperglycemic activity in STZ-induced diabetic mice, and shows improvement in oral glucose tolerance and body weight, which justi ﬁ es the claimed use of the plant in ameliorating diabetes mellitus in Ethiopian folk medicine.
