Re-Formulation of Mean King’s Problem Using Shannon’s Entropy

Mean King’s problem is formulated as a retrodiction problem among noncommutative observables. In this paper, we reformulate Mean King’s problem using Shannon’s entropy as a first step of introducing quantum uncertainty relation with delayed classical information. As a result, we give informational and statistical meanings to the estimation on Mean King problem. As its application, we give an alternative proof of nonexistence of solutions of Mean King’s problem for qubit system without using entanglement.
Performance of short-day onion genotypes for nutritional quality traits of bulb

The experiment was conducted to evaluate the short-day onion genotypes for quality attributes during kharif 2017. Among thirty genotypes evaluated, the highest reducing sugars were recorded from the genotype COHBON03 (3.83%). The highest non-reducing sugars were recorded from the genotype COHBON08 (3.52%). The highest total sugars were recorded from the genotype COHBON03 (6.45%). The highest pyruvic acid content was recorded from the genotype COHBON17 (2.31 μmol/g). These genotypes can be used for commercial cultivation with high non reducing sugars, since those genotypes having high non reducing sugars and high pungency could have longer storability. Furthermore, these genotypes can be used as parental material in the quality improvement of bulb onion.
Switching Model Predictive Control for a Quadrotor Helicopter under Severe Environmental Flight Conditions

Abstract In this article a switching Model Predictive Controller for the attitude and hovering control of a prototype Unmanned quadrotor Helicopter (UqH) subject to atmospheric disturbances is presented. The control scheme is computed based on Piecewise Affine (PWA) models of the UqH's attitude and altitude dynamics, where the effects of the atmospheric turbulence are taken into consideration as additive disturbances. The switching of the MPC scheme is ruled by the estimation and the rate of the rotation angles, for the altitude and attitude control correspondingly. Extended experimental studies indicate the overall scheme's efficiency in hovering scenarios despite the applied wind–disturbances.
Future experimental improvement for the search of lepton-number-violating processes in the e μ sector

The conservation of lepton flavor and total lepton number are no longer guaranteed in the Standard Model after the discovery of neutrino oscillations. The ${\ensuremath{\mu}}^{\ensuremath{-}}+N(A,Z)\ensuremath{\rightarrow}{e}^{+}+N(A,Z\ensuremath{-}2)$ conversion in a muonic atom is one of the most promising channels to investigate the lepton number violation processes, and measurement of the ${\ensuremath{\mu}}^{\ensuremath{-}}\ensuremath{-}{e}^{+}$ conversion is planned in future ${\ensuremath{\mu}}^{\ensuremath{-}}\ensuremath{-}{e}^{\ensuremath{-}}$ conversion experiments with a muonic atom in a muon-stopping target. This article discusses experimental strategies to maximize the sensitivity of the ${\ensuremath{\mu}}^{\ensuremath{-}}\ensuremath{-}{e}^{+}$ conversion experiment by introducing the new requirement of the mass relation of $M(A,Z\ensuremath{-}2)lM(A,Z\ensuremath{-}1)$, where $M(A,Z)$ is the mass of the muon-stopping target nucleus, to eliminate the backgrounds from radiative muon capture. The sensitivity of the ${\ensuremath{\mu}}^{\ensuremath{-}}\ensuremath{-}{e}^{+}$ conversion is expected to be improved by 4 orders of magnitude in forthcoming experiments using a proper target nucleus that satisfies the mass relation. The most promising isotopes found are $^{40}\mathrm{Ca}$ and $^{32}\mathrm{S}$.
Determination of natural and synthetic oestrogens in surface water using gas chromatography-mass spectrometry

Abstract A simple and sensitive gas chromatography method was developed to determine a group of oestrogens in surface water. In the first stage of analysis, enzymatic hydrolysis of oestrogen metabolites with glucuronidase AS-HP was performed. Free compounds were extracted from 200 mL of water sample on C18 SPE column (6 mL, 1000 mg). The evaporated extract was subjected to derivatisation with a mixture of MSTFA/NH4I/DTT (1000:2:5, v/w/w). The separation of the analytes on HP-5ms capillary column was conducted. The method was validated according to the Commission Decision 2002/657/EC. Recovery in spiked samples ranged from 90% to 120 % with standard deviation lower than 30% for all examined compounds. The decision limit and detection capability of five oestrogens were in the range of 0.3-0.6 ng L-1 and 0.5-0.9 ng L-1, respectively. Nineteen water samples collected from different sites of several Polish rivers and lakes were tested for the presence of oestrogens. Some target compounds such as 17α-oestradiol, 17β-oestradiol, oestrone, oestriol, and 17α-ethynyloestradiol were found in trace amounts in the analysed samples. The highest concentration observed for oestradiol reached 23 ng L-1.
Review of Field Survey Practices on (Mammalia: Chiroptera): A Working Guide for Junior Mammalogist in Ethiopia

Bats are considered sensitive indicators of the health of the wider environment and their population trends will reflect changes in climate, water quality and agricultural practices. However, our knowledge on bat biodiversity is in its infancy. Therefore, this paper was aimed at reviewing field survey practices on bats as a working guide for junior mammalogist in Ethiopia. The information presented in this review was collected from previous studies of existing mammalogy and wildlife ecology literatures. The summary of the review gives a common picture of valuable field survey practices and chiropteran count protocols. Catching is one of the tool for collection of bat species from their ecological zones. Of this, mist-nets are most commonly used to catch bats and have the advantage of being light, easily portable and easily erectable in the field. Moreover, harp-traps are less portable and have a smaller catching surface than mist-nets. Keys based on external features are the most useful identification tools in the field and may reduce the need to kill animals. In addition to catching individuals, bats can be surveyed, and numbers estimated by using observational techniques. Furthermore, field teams must include local collaborators that are experienced with working in the project site being stipulated. All personnel that will be handling bats need to have pre-exposure rabies vaccination series. Monitoring population trends of bats is an essential component of bat conservation. Generally, chiropteran field works should follow standard field survey protocols to fill the existing Knowledge gap in bats that will aid conservation practices.
Elevated Plasma Histone H4 Levels Are an Important Risk Factor in the Development of Septic Cardiomyopathy

Background: Myocardial impairment is a major complication and an important prognostic predictor of sepsis. Therefore, early and accurate diagnosis as well as timely management of septic cardiomyopathy is critical to achieve favorable outcomes. Aims: To investigate the risk factors of septic cardiomyopathy. Study Design: Cross-sectional study. Methods: This study performed between May 2016 and June 2018 recruited 93 septic patients from the intensive care unit. All patients received standardized treatments. Septic patients were divided into two groups: non cardiomyopathy (n=45) and septic cardiomyopathy group (n=48). Blood samples were collected and transthoracic echocardiography was performed within 24 hours of intensive care unit admission. Septic patients with one ultrasound abnormality but no history of heart disease were diagnosed as having septic cardiomyopathy. Plasma histones, cardiac troponin I, and N-terminal pro-brain natriuretic peptide were measured using ELISA. Sequential Organ Failure Assessment scores, vasopressor use, and the outcomes of intensive care unit stay were analyzed. Spearman rank analysis was used to determine the correlation between plasma histone H4 and other parameters. Binary logistic regression and receiver operating characteristic curve analysis were used to determine the risk factors for septic cardiomyopathy. Results: Compared with the non-cardiomyopathy group, the septic cardiomyopathy group had significantly higher plasma H4 and cardiac troponin I levels, a higher Sequential Organ Failure Assessment score, more frequent vasopressor use, and a higher mortality rate (p<0.05). Plasma histone H4 levels positively correlated with cardiac troponin I (r=0.577, p<0.001), N-terminal pro-brain natriuretic peptide (r=0.349, p=0.001), and Sequential Organ Failure Assessment scores (r=0.469, p<0.001). Binary logistic regression and receiver operating characteristic curve analyses revealed that elevated plasma histone H4 levels and vasopressor use were important risk factors for septic cardiomyopathy (p<0.05). Conclusion: Elevated plasma histone H4 levels could be used to predict septic cardiomyopathy in patients with sepsis.
Models for Understanding Resistance to Chemotherapy in Liver Cancer

The lack of response to pharmacological treatment constitutes a substantial limitation in the handling of patients with primary liver cancers (PLCs). The existence of active mechanisms of chemoresistance (MOCs) in hepatocellular carcinoma, cholangiocarcinoma, and hepatoblastoma hampers the usefulness of chemotherapy. A better understanding of MOCs is needed to develop strategies able to overcome drug refractoriness in PLCs. With this aim, several experimental models are commonly used. These include in vitro cell-free assays using subcellular systems; studies with primary cell cultures; cancer cell lines or heterologous expression systems; multicellular models, such as spheroids and organoids; and a variety of in vivo models in rodents, such as subcutaneous and orthotopic tumor xenografts or chemically or genetically induced liver carcinogenesis. Novel methods to perform programmed genomic edition and more efficient techniques to isolate circulating microvesicles offer new opportunities for establishing useful experimental tools for understanding the resistance to chemotherapy in PLCs. In the present review, using three criteria for information organization: (1) level of research; (2) type of MOC; and (3) type of PLC, we have summarized the advantages and limitations of the armamentarium available in the field of pharmacological investigation of PLC chemoresistance.
Relationship Power Imbalance and Known Predictors of Intimate Partner Violence in Couples Planning to Get Married: A Baseline Analysis of the AMAR Cohort Study

The increased interest on measuring violence in romantic relationships has led to the identification of some risk factors for intimate partner violence (IPV) in its different forms. Some of them are often present from the onset of the relationships. However, little attention has been paid to the engagement period. This might be, in part, due to the cognitive dissonance that hinders partners reporting intimate violence when they are planning their wedding. The purpose of our study is to test the association between the individual perception of relationship power imbalance (RPI)—a possible indirect measure of intimate violence—and known predictors of IPV. To test this hypothesis, a total of 254 premarital couples taking part in a dynamic prospective cohort study completed a questionnaire with questions about the perception of RPI and referred predictors of IPV. Results showed a positive correlation between the perception of RPI and known predictors of IPV. These findings suggest that RPI is a powerful indirect measure to detect situations that might imply a mild form of IPV and that could evolve into stronger presentations of violence later in marriage. Noticing the presence of RPI before marriage could encourage the prevention and development of personal and relational strategies to avoid the consolidation of violent dynamics within the marital relationship.
Isolation and Characterization of Phenol-Degrading Microorganism: Recent Advances

Phenol is among the common toxic environmental pollutants that occur naturally and also originated from industrial effluents. Biodegradation is a major mechanism for the removal of pollutants from a contaminated site. The focal point of this review was on the recent researches on isolation and characterization of phenol degrading microorganisms mainly by bacteria, fungi and yeast from places around the world. Scientists are interested to have their own isolates because there are no individual organisms or groups of organisms that were universally appropriate and applicable for bioremediation since the place of origin does play a role in determining the important properties of microorganisms. The compatibility of the application site as well as thebiochemical and physiological potential of the microbes should be considered. Overall, bacteria were generally capable as biodegradation agents in aquatic systems, while fungi play a greaterrole in terrestrial system
Aspects of Process Variables in Stamping Press Lines

This study investigates solving production problems in an automotive stamping plant using Finite Element (FE) analysis. The fundamentals of stamping, metal plasticity and FE analysis are developed. In this paper, we provide the basis for a simulation of the stamping of a production part, the automotive rear floorpan. On-plant factorial Design of Experiments (DoE) were simulated using the floorpan model. The accuracy of the simulations was undetermined because of variability in the DoE results. Predictions of flange shape, wrinkling and thickness show qualitative agreement with manufactured parts and indicate that simulating an industrial part is feasible.
Heparan Sulfate Structure Affects Autophagy, Lifespan, Responses to Oxidative Stress, and Cell Degeneration in Drosophila parkin Mutants

Autophagy is a catabolic process that provides cells with energy and molecular building blocks during nutritional stress. Autophagy also removes misfolded proteins and damaged organelles, a critical mechanism for cellular repair. Earlier work demonstrated that heparan sulfate proteoglycans, an abundant class of carbohydrate-modified proteins found on cell surfaces and in the extracellular matrix, suppress basal levels of autophagy in several cell types during development in Drosophila melanogaster. In studies reported here, we examined the capacity of heparan sulfate synthesis to influence events affected by autophagy, including lifespan, resistance to reactive oxygen species (ROS) stress, and accumulation of ubiquitin-modified proteins in the brain. Compromising heparan sulfate synthesis increased autophagy-dependent processes, evident by extended lifespan, increased resistance to ROS, and reduced accumulation of ubiquitin-modified proteins in the brains of ROS exposed adults. The capacity of altering heparan sulfate biosynthesis to protect cells from injury was also evaluated in two different models of neurodegeneration, overexpression of Presenilin and parkin mutants. Presenilin overexpression in the retina produces cell loss, and compromising heparan sulfate biosynthesis rescued retinal patterning and size abnormalities in these animals. parkin is the fly homolog of human PARK2, one of the genes responsible for juvenile onset Parkinson’s Disease. Parkin is involved in mitochondrial surveillance and compromising parkin function results in degeneration of both flight muscle and dopaminergic neurons in Drosophila. Altering heparan sulfate biosynthesis suppressed flight muscle degeneration and mitochondrial dysmorphology, indicating that activation of autophagy-mediated removal of mitochondria (mitophagy) is potentiated in these animals. These findings provide in vivo evidence that altering the levels of heparan sulfate synthesis activates autophagy and can provide protection from a variety of cellular stressors.
Measuring the Effect of a Tobacco Media Campaign Among Nonsmoking Children and Adolescents

Tobacco use is the single most preventable cause of death in the United States, accounting for approximately 430,000 deaths annually, or one in every five (US Department of Health and Human Services [DHHS], 1999a). Despite a reduction in smoking prevalence among adults in the US from 42.4% in 1965 to 24.7% in 1997 (DHHS, 1999b), cigarette smoking among adolescents increased significantly from 1991 to 1997 in each grade from 9-12 (DHHS, 1999a). Data from the 1999 Youth Risk Behavior Survey revealed that 34.8% of high school students smoked cigarettes on one or more of the 30 days preceding the survey and were considered current smokers (DHHS, 2000a).
The functional anatomy of cognitive control: A domain‐general brain network for uncertainty processing

Cognitive control is the coordination of mental operations under conditions of uncertainty in accordance with goal‐directed behaviors, and plays a key role in the domains of executive control, working memory, and decision‐making. Although there is emerging evidence of common involvement of the cognitive control network (CCN) of the brain in these domains, this network has mostly been linked to the processing of conflict, which is just one case of an increase in uncertainty. Here, we conducted an activation‐likelihood‐estimation‐based large‐scale meta‐analysis of 289 functional magnetic resonance imaging studies in the three domains to examine the common involvement of the CCN in uncertainty processing by contrasting the high‐uncertainty versus low‐uncertainty conditions. We found a general association between increase in uncertainty and an activation increase in regions of the CCN, including the frontoparietal network (comprising the frontal eye fields, the areas near and along the intraparietal sulcus, and the dorsolateral prefrontal cortex), the cingulo‐opercular network (including the anterior cingulate cortex extending to the supplementary motor area, and the anterior insular cortex), and a subcortical structure (the striatum). These results demonstrate that the CCN is a domain‐general construct underlying uncertainty processing to support goal‐directed behaviors.
Design of a 3–10 GHz UWB CMOS T/R switch

A 3–10 GHz broadband CMOS T/R Switch for ultra‐wideband (UWB) transceiver is proposed. This broadband CMOS transmit/receive (T/R) Switch is fabricated based on the 0.18 μm 1P6M standard CMOS process. On‐chip measurement of the CMOS T/R Switch is performed. The insertion loss of the proposed CMOS T/R Switch is about 3.1 ± 1.3 dB. The return losses at both input and output terminals are higher than 14 dB. It is also characterized with 25–34 dB isolation and 18–20 dBm input P1dB. The broadband CMOS T/R Switch shows highly linear phase and group delay of 20 ± 10 ps from 10 MHz to 15 GHz. It can be easily integrated with other CMOS RFICs to form on‐chip transceivers for various UWB applications. © 2007 Wiley Periodicals, Inc.

Return migration of the Atlantic salmon in the Tana River : distribution and exploitation of radiotagged multi-sea-winter salmon

A total of 174 multi-sea-winter Atlantic salmon (75-115 cm fork length) were radiotagged in the Tanafjord in 1992-1993 and their upstream migration and exploitation in the Tana River (Teno) were studied. Of the tagged fish, 75% and 77% entered the river, and 40% and 69% of them were later recaptured in 1992 and 1993, respectively. The lower 60 km of the river accounted for 36% of the recaptures. Gillnets and weirs took 68% of the fish recaptured in the river in 1992 but only 40% in 1993, the rest being caught by rod and line. Weirs caught more recently entered salmon than gillnets. Rod and line fishery caught smaller fish than gillnets and weirs. There were no differences in the size distributions between the initially tagged salmon, those that entered the river, were recaptured in the river, or the ones survived until spawning. Exploitation rates (n recaptured fish /n entered the river ) were the highest in the upper reaches of the river system.
Evidence of Radical Intermediate Generated in the Electrochemical Oxidation of Iodide

We present evidence of the generation of radical ion formation during the oxidation of iodide on a fluorine doped tin oxide (FTO) electrode in acetonitrile. The cyclic voltammograms for the oxidation of iodide and triiodide on FTO are significantly different as in the case of the oxidation of Pt electrode. These differences are assigned to kinetic differences on the FTO surface that require significant over potentials to drive the oxidation of iodide and triiodide. We propose that at the highly positive potentials the iodine radical intermediate, I·, becomes thermodynamically stable at FTO. The radical nature of the intermediate was verified by the formation of radicals of the usual traps of 5,5-dimethyl-1-pyrroline N-oxide (DMPO) and 2,2,5,5 tetramethyl-1-pyrroline N-oxide (TMPO) when these were added to an electrolyzed solution. Irradiation of an iodine solution causes the homolytic cleavage of I2 and yields the same radical intermediate with TMPO as in the electrolysis experiment. Similar results were obtained from the electrolysis of bromide solutions upon addition of TMPO. Short term electrolysis (< 1 h) gives triiodide as a final product while long-term electrolysis (> 17 h) yields additional byproducts. Byproducts were determined to be organoiodines by gas chromatography-mass spectrometry (GC-MS). Overall, our results are consistent with iodine atoms reacting with the electrolyte during electrolysis at the FTO electrode and with a sequential two-electron transfer process.
DIRECT AND INVERSE PROBLEMS FOR THE EVERSION OF A SPHERICAL SHELL

Motivated by an interest in material parameter determination for a structure with residual stresses, we revisit the classical eversion pr oblem of a spherical shell, as studied by Ericksen, 1955 and more recently Johnson and Hoger, 1993. The spherical shell is made of an isotropic, incompressible, hyperelastic, Mooney-Rivlin material. In the direct problem, we examine the dependence of the elasticity tensor coefficients on residual and initial stresses and represent it for three numerical cases. In the inverse problem, we analyse the effect of measurement uncertainties on the determined values of material parameters and we suggest an experimental protocol that allows for a robust recovery of these parameters.
RETRACTED: MiR‐93 blocks cell cycle progression and promotes apoptosis in uterine leiomyoma cells by targeting CCND1

Uterine leiomyoma (UL) is the most common type of benign tumor in the women's reproductive system. A number of genes has been found to play an important role in the initiation and progression of UL, including miRNAs. In this study, our results exhibited that miR‐93, a member of mir‐106b‐25 cluster, significantly reduced the cell viability, promoted cell cycle arrest, caused apoptosis, and inhibited migration in UL cells (p < .01). Moreover, our results have provided experimental evidence that miR‐93 regulated the biological functions of UL cells by targeting CCND1.
