Thermo-mechanical reliability is one major challenge in solid-state lighting for automotive applications. Mismatches in the coefficients of thermal expansion (CTE) between high-power LED packages and substrates paired with temperature changes induce mechanical stress. This leads to thermal degradation by crack formation in the solder interconnect and/or delamination in the substrate, which in turn increases junction temperature, thus decreasing light output and reducing the lifetime. A reliability study with a total of 1,800 samples - segmented in nine LED types and five solder pastes - is performed to investigate degradation and understand the influence of solder material and LED package design. The results are presented in two papers. Initial characterization of the LEDs was handled in the first paper. This second paper focuses on degradation and lifetime. Overall, more than 40,000 transient thermal analysis (TTA) and 9,000 scanning acoustic microscopy (SAM) measurements were taken to evaluate degradation during accelerated aging of 1,500 thermal shock cycles. Six different failure modes were observed, which were distinguishable by only using TTA data. For the reliability evaluation, crack ratio was determined by SAM images while thermal degradation as well as mean lifetime were determined using TTA data. Multiple observations were made within this study. First: SAM and TTA data correlated very well; Second: Higher silver content and additives in the solder paste reduce crack growth and increases lifetime; Third: Thick film ceramic LEDs reach significant longer lifetimes than thin film ceramic LEDs, and copper lead-frame LEDs reached by far the longest lifetimes; Fourth: A pad design with a greater pad size, smaller gaps and balanced size ratio between electrical and thermal pad is advantageous; Fifth: Voiding (below 10%) has no significant influence on the reliability.


Self‐monitoring, one of the most important behaviors for successful weight loss, can be facilitated through mobile health applications (mHealth apps). Therefore, it is of interest to determine whether consistent users of these apps succeed in achieving their weight goals. This study used data from an mHealth app that enabled tracking of caloric intake, body weight, and physical activity and provided a caloric budget depending on weight goal. The primary objective was to evaluate adherence to caloric budget and body weight change among the most consistent (i.e., daily) trackers of caloric intake over a calendar year (n = 9372, 50% male).

The objective of 'A Study of Holiday Time Behavior of the Deaf Living in Bangkok' is to study the life style of the deaf living in Bangkok and how they spend their leisure on holiday whether it is similar or dissimilar to that of the general public. The sample population is the deaf living in Bangkok, without limitations of age or sex, totaling 119. Interview and behavior observation forms are used for data collection. The research found that the deaf living in Bangkok Metropolitan have one or two holidays per week. Their activities on those days include personal work, house work, study, employment work, social and religious activities and leisure. About 68.9 percent of the deaf prefer leisure, both at home and outside. The activities being engaged at home are respectively: watching T.V, talking, reading newspaper and a variety of books, hobbies, sitting or lying in repose, video watching, games, socializing, exercising and watching sport. As for the activities being engaged outside of home, the following are in order of preference: window shopping at department stores, meeting with friends, playing sports, watching movies, visiting relatives, eating food and dancing. The majority, 77.8 percent, of the deaf, regardless of sex, age or marital status, meet with friends on holidays.

It is a commonplace that wealth is less equally distributed than is earned income. Moreover, while it is widely recognized that there is an efficiency, or incentive, argument that may justify earnings inequality, there is no similar consensus as to the role of wealth inequality. The purpose of this paper is to provide suggestive answers to the two questions implicit here by exhibiting, for a family of models built on a life cycle basis, the relationship between the two distributions. It will be found that the wealth distribution is necessarily more unequal than earnings and a specific measure will be constructed. The models take the earnings distribution as an input and thus at the positive level one can feed in the observed distribution of (net) earned income and derive an estimate of the steady-state wealth distribution. Alternatively, if one feeds in the preferred (net) earned income distribution one obtains the implied distribution of wealth. In both cases the wealth distribution may be affected by bequest patterns that are emphasized in our analysis. The paper is divided into four parts in which models of different degrees of complexity are presented. These models focus on different aspects of the problem under review. In Section I we develop the basic model of selfish life cycle behaviour with earnings inequality; a crude, but popular, inequality measure is proposed (related to the share of the top group) according to which the inequality of wealth is necessarily more than twice that of net earnings. An objection to this model is that it implies zero bequests. In subsequent sections we consider two explanations of bequests. We first examine, in Section II, the implications of capital market imperfections which make it difficult to die penniless when one does not know the date of death and does not want to run the risk of having to live penniless. The second type of bequest arises from a desire to equalize, or smooth, consumption between generations of the same dynasty. This involves a relaxation of the selfishness postulated in Sections I and II. However, manifestations of altruism are restricted in several ways. In Section III we take the model of Section II, assume that net earnings within each dynasty are constant over time, and consider the consequences of voluntary bequests by those who inherit large estates as a result of the pattern of mortality of their ancestors. It will be shown that in this case altruism increases the inequality of wealth while reducing that of consumption. Wage growth (within each dynasty) would reduce the manifestations of altruism as bequests are designed to equalize the relative consumption levels of father and son; at realistic growth rates of earnings no altruistic bequest would be generated as a byproduct of random mortality. At this point a fundamental asymmetry underlying the models comes into


Petroleum exploration has strongly contributed to the knowledge of the post-Hercynian structural history of the Golfe du Lion. It shows three stages: (1) Pyrenean orogenesis which started in the Late Cretaceous and culminated during the Eocene (40-75 Ma), (2) Oligocene rifting associated with the oceanic accretion of the Provencal basin, and (3) post-Messinian deformations due to salt tectonics. Pyrenean deformation of the area seems to have been controlled by its Hercynian inheritance: the major transcurrent faults of the Cevenole belt, Nimes, and the Durance. They favored displacement of the deformation in a northeasterly direction along the fault corridors, inside which the overthrust units were put into place. These east-west-oriented structures show northward vergence. The Pyrenean axial zone in this downthrown part of the belt consist of progressively more northerly units offset by transverse faults. The Oligocene rifting is represented by a series of horsts and deeply subsiding grabens linked to preexisting major faults. The horst are deeply eroded and the Mesozoic carbonates are karstified. The extension of the Messinian evaporitic deposits known throughout the Mediterranean basin is located north of the shallower deep-water well. The gravitational deformation of the salt is expressed by a large number of listric faults whichmore » originate in the salt bodies.

Empowering the frontline employees cannot work in vacuum. Empowerment of employees, while very important, requires an important requirements and conditions. Information and information technology are predicted to act as the most important requirements and qualities for empowering 21st century workforce. Hence, this article aims at testing the impact of information in general(GE) and information technology (IT) in particular on the impact of empowering employees in the private school sector in Northern region in Jordan. A survey questionnaire was developed to reflect a simple model of the presumed relationships. A sample of 120 employees has participated in the survey and data were collected and analyzed using means, regressions and orrelations to test such impact. The study analysis and results approved the study assumptions indicating that there is a significant impact of information technology variables (Adjusted R Square= 0.035), and information variables in general on the empowerment of the frontline employees in the private school sector in Jordan (.077), and p < 0.05. Recommendation for both academics and managers were provided in this research.

In this paper, we have analyzed the performance of coherent optical systems using cascaded optical amplifiers. The relative performance of binary asynchronous, binary synchronous and M-ary FSK systems are compared in terms of power penalties due to amplifier input power and noise accumulation at various bit rates of operation. This completes the previous investigations that were limited to the analysis of photonic amplifier based coherent optical asynchronous systems.


Like much else in medical practice, research, and education, the teaching of neuroanatomy is facing changing times. For the two of us, who lead courses for medical students at Harvard in the United States and at Oxford in the United Kingdom, teaching neuroanatomy has been a career highlight, and we consider ourselves extremely fortunate to be able to influence the next generation of physicians. For us the job is rewarding, stimulating, and itself educational, but we also recognize a number of growing challenges as we look toward the future. For one, the perception of neuroanatomy from the medical community is often a conflicted one. Professional prizes and distinctions are more commonly awarded for research rather than for high-quality teaching, no matter what the subject, but teaching medical students neuroanatomy in particular can be seen as a thankless task. Both of us have had the experience of introducing ourselves to colleagues as neuroanatomy course leaders, only to be met with what could best be described as a combination of pity and skepticism. Pity, presumably because neuroanatomy is seen as a difficult and unenviable subject to teach, and skepticism, presumably because non-neurologist colleagues are doubtful of its importance in this day and age. Perhaps more troubling, a surprising number of practicing clinical neurologists, when specifically asked, admit that they did not particularly enjoy medical school neuroanatomy—not that the subject matter did not appeal to them, but that their instruction in it left much to be desired. However, both of us have also had the pleasure of meeting former students who are now accomplished clinicians or researchers and hearing accounts of the lasting stimulation and motivation that learning neuroanatomy provided. Many of the challenges facing neuroanatomy teachers are generational in nature. The students are different, the technology is different, the available time and resources are different, and the faculty members are different. Although the subject matter would appear to be the same, the aspects of it that are deemed the most fundamental and most relevant to clinical practice do change over time, as our understanding of human neurological disease advances, our ability to visualize anatomical lesions through imaging increases, and our capacity to tailor individual treatments for patients expands. In our opinion, however, the beauty of the nervous system, the logic of (most of ) its pathways, and the possibility (indeed, necessity) of clinicoanatomical correlation in proper diagnosis combine for a subject that in some ways is an ideal one for preclinical students. After all, even the most inexperienced novice can localize from first principles if familiar with the symptoms, examination findings, and relevant functional anatomy of a case in enough detail. How much more exciting it is for a student to realize that learning neuroanatomy allows her to truly "figure out" a case from scratch, rather than be told that it will take 40 more years of experience before she can recognize such-and-such a disease correctly. Moreover, considerable time and expense can be saved by establishing and narrowing down the differential diagnosis based on neuroanatomical principles, an important factor in this cost-conscious age. During a recent sabbatical visit, we started comparing neuroanatomical teaching between Harvard and Oxford. In both cases, practical laboratory sessions are integral parts of a larger course. At Oxford, neuroanatomy is taught as part of a medical neuroscience course given to undergraduates pursuing careers in clinical


Sarah Faye Cohen is Information Literacy Librarian; Timothy Miner is Emergent Media Center, Producer; Laurent Nishikawa is Emergent Media Center, Producer all atChamplain College At a campus that percolates the power and promise of play, the Champlain College Library asked students from our Electronic Game Design Program and the Emergent Media Center to create a game to complement our Information Literacy (IL) program. Little did we know that this collaboration would lead us to question and re-envision what we mean by information literacy. As a result of this library-student collaboration, Champlain is experimenting with new, dynamic, and interesting ways to engage and invigorate our students' interest in accessing, navigating, selecting, and using information in the digital world.


This study was designed to examine the effect of the methanolic extract of the root of Cissampelos mucronata on embryo-foetal development in rats. A total of 60 nulliparous female rats weighing 143-215gm approximately 13 weeks of age in the proestrous stage were cohabited (1:1) with 60 male rats to obtain 40 pregnant rats which were assigned to four dosage groups (10 rats per group, I-IV) by random stratification to nearly equalized body weight difference between groups on gestataion day zero GD 0. Group I served as the control group while rats in Groups II, III and IV were administered with 100mgkg -1 , 200mgkg -1 and 300mgkg -1 doses of the extract respectively from implantation (GD6) to the day prior to the expected day of parturition (GD20). On GD20, the female rats were euthanized and uterine implantation data including live and dead foetuses were counted, weighed, gender determined and observed for external malformations. The results indicate that administration of the extract from gestation day 6 to 20 had no significant effect on the number of implantation sites while resorptions sites were significantly (p<0.05-0.001) high in a dose dependent manner. There was a decrease in the foetal weight, placental weight and crown rump length of the rats indicating that administration of the extract from gestation day 6 to 20 caused resorptions in pregnancy and decrease in foetal weight, placental weight and crown rump length rats in a dose dependent manner.


The experiments were carried out to study the effect of salt-stresses and ABA on the growth, photosynthesis and translocation of assimilates in bean plants. It was planed to reduce the content of GA 3 and cytokinins and increase ABA content in salinized plants. The results show that salt-stress (NaCl and concentrated nutrient solution), reduce all the investigated processes in a different degree. NaCl-stress retarded most seriously growth of apical part and blades in contrast to 7-times concentrated nutrient solution decreasing mainly the rate of root and blade growth. Photosynthesis and 14 C-translocation of 14 C-assimilates were retarded more seriously by NaCl than by 7-times concentrated nutrient. solution. In the case of seriously stressed plants GA 3 and cytokinins (more effectively) reversed the ,negative effect of stress conditions both on the photosynthesis and on the 14 C-tramslocation. On the basis of the obtained results, it seemes that changes in the rate of investigated processes in salinized plants are due to hormonal disturbances which cause directly or indirectly retardation of photosynthesis and trans-location of assimilates.


This paper presents the first, to our knowledge, lidar measurement of an industrial fire plume, which covered the north of the Paris area on 17 th April 2015. The fire started in a textile warehouse and rapidly spread by emitting large quantities of aerosols into the low troposphere. A ground based N 2 -Raman lidar performed continuous measurements during this event. Vertical profiles of the aerosol extinction coefficient, depolarization and lidar ratio are derived. A Monte Carlo algorithm was used to assess the uncertainties on the optical parameters, and to evaluate lidar inversion methods.


The invention provides a method and a device for dedusting and purifying low-temperature dry-distilled gas. When an existing granular-bed filter is used for dedusting and purifying dry-distilled gas, as a large number of tar adhesives are contained in the dry-distilled gas, dust is difficult to get separated from granular filtering materials, and therefore the dedusting efficiency is greatly decreased. The method provided by the invention comprises the following steps of: adding solid granular filtering materials from a hopper into the granular-bed filter, introducing preheated smoke from a preheated smoke inlet, introducing dust-containing dry-distilled gas into a lifting pipe of the granular-bed filter from a dust-containing dry-distilled gas inlet, introducing hot air or high-temperature smoke to the bottom of the lifting pipe, burning to remove dust and tar attached to surfaces of the granular filtering materials, blowing to send the solid granular filtering materials to a top precipitator, returning the granular filtering materials in the precipitator to the granular-bed filter for recycling, subjecting the dust-containing gas to the treatment of a dust separator, collecting dust by a dust collecting tank, and feeding the gas to a rear system for treatment. The method and device provided by the invention are used for dedusting and purifying the low-temperature dry-distilled gas.


Cyberbullying and Video Game Addiction are some of the main concerns thriving from playing PC Video Games. It is without a doubt that both hamper daily activities and ruins inter-personal relationships. This study looks at how the state of Flow affects Cyberbullying and Video Game Addiction in playing PC Games. When players experience Flow, they lose self-consciousness, and they tend to forget about their surroundings. Subsequently, they focus only on what they are doing, neglecting any change from their environment. Though studies exist that show a possible relationship between Flow and Video Game Addiction, the study goes further by determining which of the criteria of the Gaming Addiction Scale (GAS) is highly influenced by the state of Flow. Subsequently, the study aimed to know the relationship of Flow to Cyberbullying and Game Addiction to Cyberbullying. The existing survey questionnaire from the literature was prepared through Google Forms. A total of seventy-three (73) respondents answered the survey through the snowballing sampling technique. The result revealed that out of the eight (8) criteria of GAS, Salience had the highest relationship followed by Mood Modification, Tolerance, Problems, and Conflict. The higher the state of Flow, the higher the tendency for gamers to experience addiction. However, the result further revealed that Flow is not a predictor for Cyberbullying (perpetrator and victimization). Other results are discussed in the paper.


The aim of this study was to identify factors that contributed to the successful transition off academic probation for undergraduate students at MacEwan University 1 . Focus groups were conducted with volunteers enrolled in any of the main faculties/schools who had successfully to taking time off from university, changing programs, or personal growth. Students underutilized available support services while on academic probation largely due to feelings of embarrassment and shame. Recommendations for institutional improvements centered on personalized approaches that identified existing resources such as listing resources along with contact information in notification of academic probation letters sent to struggling students. Finally, those who successfully transitioned off probation also emphasized the need for personal contact with university staff to help understand the implications of academic probation, and the steps required to successfully transition off it.

The paper discusses the implications and functions of practice fetching of modern colleges and puts forward a new teaching system for the purpose of promoting university work with self-running tendencies of universities.


Several issues need to be considered in the design and control of converters for converter-interfaced distributed generators (DGs). Under fault conditions, the semiconductor devices withstand ratings must not be exceeded. The converter control strategy is also required to facilitate fault ride through (FRT) capability. On the other hand, protection against fault is better served by employing control strategies that allow the converter-interfaced DGs to contribute short duration fault current sufficient to aid the detection of faults. Semiconductor devices protection and FRT capability have the same objective of limiting the magnitude of the fault current. Protection coordination in the complex DG-integrated network is difficult and may result in protection settings that are not optimal or contribute to long relay operating times that may impact FRT support. On this basis, this study proposes the de-coupling of the protection solution from FRT and semiconductor device considerations. This study critically reviews various strategies proposed in the literature for the protection of the DG-integrated distribution system and develops an argument that aims to influence a paradigm shift towards voltage-based protection that may see protection design decoupled from inverter design and control, since fault current contribution may not be required to achieve effective protection.


Correction for 'Graph neural network based coarse-grained mapping prediction' by Zhiheng Li et al., Chem. Sci., 2020, 11, 9524–9531, DOI: 10.1039/D0SC02458A.


The road surface is one of the most important factors that have influence on the current traffic noise. Usually, for dense surfaces, impacts of the tyre on the pavement generate vibrations which are the dominant mechanisms in the tyre–road noise. In this study, the effect of muffling these vibrations, by the incorporation of crumb rubber (CR) from wasted tyres into asphalt pavements, has been evaluated acoustically. Close proximity measurements have been carried out to register the sound emission generated in the contact zone between a reference tyre and an experimental asphalt pavement with CR. The analysis of the measurements indicates that the incorporation of CR as well as the air voids content has less influence than the macrotexture of the road surface on the acoustical behaviour of this experimental asphalt pavement.


A systematic study of the parameter space of graphene chemical vapor deposition (CVD) on polycrystalline Cu foils is presented, aiming at a more fundamental process rationale in particular regarding the choice of carbon precursor and mitigation of Cu sublimation. CH4 as precursor requires H2 dilution and temperatures ≥1000 °C to keep the Cu surface reduced and yield a high-quality, complete monolayer graphene coverage. The H2 atmosphere etches as-grown graphene; hence, maintaining a balanced CH4/H2 ratio is critical. Such balance is more easily achieved at low-pressure conditions, at which however Cu sublimation reaches deleterious levels. In contrast, C6H6 as precursor requires no reactive diluent and consistently gives similar graphene quality at 100–150 °C lower temperatures. The lower process temperature and more robust processing conditions allow the problem of Cu sublimation to be effectively addressed. Graphene formation is not inherently self-limited to a monolayer for any of the precursors. Rathe...


3-(1-Hydroxyiminoethyl)-1-phenyl-4-hydro-1,2,4-triazin-5,6-dione, has been prepared from the chiral 1-phenyl-3-acetyloxime-5-benzyl-4,5-dihydro-1,2,4-triazin-6-one in the presence of organotin(IV) compounds in methanol solution. It crystallizes as a 1:1 methanol solvate in the monoclinic space group P 2 1 /c with the lattice parameters: a = 1517.6(1), b = 563.64(3), c=1500.34(13) pm and β = 90.35(1)°. The molecules, in which the heterocyclic ring is planar, are dimer via strong oxime-methanol and methanol-dione hydrogen bonds and by additional N-H---O bridges linking the heterocyclic rings.


This letter formulates a class of generic optimal formation control problems for second-order multiagent systems, where agents are steered to achieve the optimal formation determined by a convex optimization problem with generic formation constraints and admissible range constraints. These constraints determine the geometric pattern and limit the range of the optimal formation, respectively. A generic optimal algorithm based on the primal-dual dynamics is proposed for various formation requirements. Based on Lyapunov stability and optimization theories, the states of the second-order multiagent system are shown to converge to the optimal solutions. Moreover, an obstacle avoidance mechanism based on the control barrier function is introduced to make our algorithm more practical. Finally, numerical simulations illustrate the effectiveness of the proposed algorithm.

A microstrip non-reciprocal 2nd-order bandpass filter is presented by using time-modulated resonators. Quarter-wavelength resonators are loaded with varactors to miniaturize the circuit size. The varactors are reverse-biased by dc voltages and then sinusoidal waves are applied to modulate their equivalent capacitance in time-domain. Circuit analysis shows that by properly introducing phase shift between the two modulation waves, non-reciprocal transmission can be generated. To verify the proposed concept, a microstrip 2nd-order non-reciprocal bandpass filter at 1.0 GHz is designed and simulated. Results show low insertion loss in the forward transmission and large attenuation in the backward transmission, leading to 4.7 dB non-reciprocity in the transmission magnitude.


An ultrasonic method has been investigated for the quantitative recovery of density distributions of porous bodies similar to those produced by pressure‐assisted sintering of powders. It relies upon the strong relationship between the ultrasonic velocity and the density of a porous body. Noncontact laser‐generated/interferometrically detected ultrasound has been propagated along ray paths in a planar cross section of model samples and ultrasonic time‐of‐flight projections obtained. Two approaches have been explored for reconstructing the internal velocity (and thus density) distribution from the projection data. The first approach was a standard convolution backprojection algorithm used frequently in computerized tomographic reconstruction. A combination of ray bending (due to refraction by the velocity gradient within the sample), noise in the projections, and practical limits upon the number of projections that can be obtained have all adversely affected the reconstruction quality of this method. The second approach explored a (nontomographic) nonlinear least‐squares approach. It utilized a priori information about the general functional form of the velocity (density) distribution (which is available from predictive models of the densification process) and gave significantly better results for samples with simple geometry even when projection data were sparse.


We study transport in anisotropic spin-$1/2$ chains governed by the integrable XXZ model with and without integrability-breaking perturbations at high temperatures ($T\to \infty$) using a hybrid approach that combines exact sum-rules with judiciously chosen Ans\"atze. In the integrable XXZ model we find (i) super-diffusion at the isotropic (Heisenberg) point, with frequency dependent conductivity $ \sigma'(\omega\to 0) \sim |\omega|^{\alpha}$, where $\alpha=-3/7$ in close numerical agreement with recent $t$-DMRG computations; (ii) a continuously drifting exponent from $\alpha=-1^+$ in the XY limit of the model to $\alpha>0$ within the Ising regime; and (iii) a diffusion constant saturating in the XY coupling deep in the Ising limit. We consider two kinds of integrability breaking perturbations --- a simple next-nearest-neighbor spin-flip term ($J_2$) and a three-spin assisted variant ($t_2$) natural in the fermion particle representation of the spin chain. In the first case we discover a remarkable sensitivity of $\sigma(\omega)$ to the sign of $J_2$, with enhanced low frequency spectral weight and a pronounced upward shift in the magnitude of $\alpha$ for $J_2>0$. Perhaps even more surprising, we find sub-diffusion ($\alpha>0$) over a range of $J_2<0$. By contrast, the effects of the "fermionic" three-spin perturbation are sign symmetric; this perturbation produces a clearly observable hydrodynamic relaxation. At large strength of the integrability breaking term $J_2\to \pm \infty$ the problem is effectively non-interacting (fermions hopping on odd and even sublattices) and we find $\alpha\to -1$ behavior reminiscent of the XY limit of the XXZ chain. Exact diagonalization studies largely corroborate these findings.


The human body is in a posture every minute of every day: it can be static, such as when resting, or dynamic, such as when walking. It is quite frequent that people assume poor postures during the day and they make their bodies more susceptible to injuries. Considering this, prevention assumes a central role as it can avoid damage and pain in day-to-day life, but it is very poorly practiced in the majority of countries, even in the Western world. Moreover, diagnosis and assessments for postural abnormalities are demanded to few specialized centers, which usually perform anecdotal or subjective evaluations. In this paper, we propose an innovative model to face up to postural abnormalities starting from a two-stage approach that have been conceived and are being implemented by the KISS-Health Project. The idea consists of two units: a) the Mobile Diagnostic System, which is composed of both hardware and software components and it will permit a first assessment of human posture in order to identify people at risk; b) the Laboratory Diagnostic System, which will investigate more accurately the complete postural configuration of the subject going under exam. It is our goal to promote an integrated approach that, based on scientific and economical evidences, will reduce the costs related to postural abnormalities.


We report on the observation of terahertz radiation induced photogalvanic currents in semiconductor quantum well structures with one-dimensional lateral periodic potential. The current response is well described by the phenomenological theory of the superposition of the linear and circular photogalvanic effects. Experimental data demonstrate that the inversion asymmetry of semiconductor heterostructures can be controllably varied by means of electron beam lithography. The inversion asymmetry in quantum well structures is of importance for rapidly growing field of spintronics providing an effective tool for the spin manipulation by an electric field.


In the wake of the London and Manchester terror attacks, experts are calling on the government to involve young people and community groups in creating effective ways to address marginalisation and extremist views


With the advent of modern smartphones, the possibility of embedding measurement software into apps to automatically trigger background performance tests constitutes an interesting data source for mobile network operators (MNOs) to complement dedicated testing campaigns as well as user-triggered speedtests. These backgroundtriggered measurements enable a higher level of control over the time and place of measurements. However, the shared resources offered by mobile networks can not be used in an unfettered way, which limits the measurement frequency & volume possible in such measurement campaigns. Previous work has shown that LTE cell load can be inferred from signal quality measurements by devices in an experimental setup. This work examines the possibilities of inferring the time series of key performance indicators in a live LTE network using data collected by way of background-triggered crowdsourcing measurements. Based on two matched datasets consisting of a) background-triggered crowdsourcing measurements and b) radio access network performance indicators, LSTM recurrent neural network models for time series regression are compared against different regression methods based on linear and decision tree-based models with respect to performance and model interpretability. Both the magnitude of the load curves and the temporal location of peak loads in LTE cells can be reliably estimated by using only background-triggered crowdsourcing data. In most scenarios, the LSTM recurrent neural network model outperformed all other models with respect to both the root mean squared error (between 4% and 40% improvement compared to the best alternative model) of the predicted time series, as well as the success ratio of temporal peak detection within the time series (between 80% and 145% improvement compared to the best alternative model). Furthermore, performance measurements collected using a background-triggered crowdsourcing approach can aid in estimating cell load when used in conjunction with signal quality. Finally, the effect of additional noise and missing data is examined and used to inform decisions about the viability of using crowdsourcing data given certain measurement conditions.


ABSTRACT We develop an extension of the Maugis-Dugdale solution for viscoelastic spheres. We show that we can define two characteristic Tabor parameters, a larger one corresponding to relaxed modulus and a smaller one for instantaneous modulus of the material. Only if both are very large (corresponding to the JKR regime, ) the pull-off load increase due to viscoelastic effect is possibly very large at large pulling speeds, as given by existing solutions and approximately equal to the ratio , and otherwise the amplification at very high speeds is much reduced and we give a very simple upper bound of the pull-off load as a function of the relaxed Tabor parameter, independently on the exact form of the viscoelastic linear modulus. An example detailed calculation is given for standard material and constant velocity of load reduction. A dependence on preload is found.


In this paper, we study sampling from a posterior derived from a neural network. We propose a new probabilistic model consisting of adding noise at every pre- and post-activation in the network, arguing that the resulting posterior can be sampled using an efficient Gibbs sampler. The Gibbs sampler attains similar performances as the state-of-the-art Monte Carlo Markov chain methods, such as the Hamiltonian Monte Carlo or the Metropolis adjusted Langevin algorithm, both on real and synthetic data. By framing our analysis in the teacher-student setting, we introduce a thermalization criterion that allows us to detect when an algorithm, when run on data with synthetic labels, fails to sample from the posterior. The criterion is based on the fact that in the teacher-student setting we can initialize an algorithm directly at equilibrium.


Video on Demand (VOD) is an important aspect in today's world due to its efficiency and availability. High demand for VOD leads to high computational and network requirements.

The review addresses the clue aspects of the book. Namely, the review concerns the conception of experiential self on different levels of inquiry, analyses models of intersubjectivity in phenomenological tradition, the nature of shame from interdisciplinary perspective. Also, the reviewer notices the author's emphasize on relationship between phenomenology and other scientific traditions. The author discusses the interdisciplinary approach to the problem. As such, the author considers antirealist position to the problem of the self, arguing about its inconsistency in relation to the phenomenologically elaborated conception of experiential minimal self. Various conceptions of identity are also under the interest in first part of the book.


Abstract With chopped high intensity optical excitation a modulation of the optical absorption in a wide wavelength-range in CdS was observed. This light induced modulation of absorption is attributed to a redistribution of carriers over levels in the band gap following the chopping frequency. With this method the energy spectrum of certain traps and recombination centers can be determined and their frequency factor and capture cross section obtained. This method permits also the analysis of fast recombination centers.


In order to study the mechanical behavior of the dredger fill silty sand in Caofeidian port, a series of direct shear creep test under different normal pressure were performed. The experimental results indicate that dredger fill silty sand only shows the creep characteristics under certain shearing stress, while under low horizontal shear stress the soil sample generates almost no creep deformation, and the instantaneous deformation grows with the increase of shear load. The normal pressure has obvious influence on the dredger fill silty sand. The bigger the normal pressure, the smaller is the total creep deformation. The relationships of strain–time and strain–stress can be expressed by the power function.


The process of cell death, or apoptosis, is commonly defined by its distinct morphological characteristic. Apoptosis is considered a vital component of various processes including normal cell turnover, proper development and functioning of the immune system, the cellular antiviral response pathway, embryonic development and chemical-induced cell death. In this study, retroviral vector was utilized as the gene delivery vehicles and the tumour-specific viral death effector VP3 as pro-apoptotic agent for malignant colon cancer cells treatment. Here, pro-apoptotic gene inducing apoptosis in CT26 colon tumour cells is reported. In addition, the activation of a typical apoptotic programme was observed in response to this therapeutic agent. An increased number of colon tumour cells suffered apoptosis upon treatment with pro-apoptotic agent. As a result, these tumour cells displayed loss of membrane asymmetry and impermeability, cell shrinkage, nuclear condensation and DNA fragmentation under H&E images. In the presence of VP3, TEM also confirmed that VP3-treated CT26 tumour cells showed apoptotic features. These results suggested that VP3 was a potential pro-apoptotic agent and the apoptosis induced by VP3 was a key anti-tumour mechanism.


All graph in this paper are connected graph and simple graph. Let G = (V,E)be a connected graph. Rainbow vertex connection is the assignment of G that has interior vertices with different colors. The minimum number of colors from the rainbow vertex coloring in graph G is called rainbow vertex connection number. If wf(u) ̸= wf(v) for two different vertext u, v ∈ V (G) then f is called antimagic labeling for graph G. Rainbow vertex antimagic coloring is a combination between rainbow coloring and antimagic labeling. Graph G is called rainbow vertex antimagic coloring 2-connection if G has at least 2 rainbow paths from u − v. Rainbow vertex antimagic coloring 2-connection to denoted as rvac2(G). In this paper, we will study rainbow vertex antimagic coloring 2-connection on a family of graphs ladder that includes H-graph Hn for n ≥ 2, slide ladder graph SLn for n ≥ 2, and graph Octa-Chain OCn for n ≥ 2.


: A field-portable multiband radiometer (Modular-Multiband Radiometer Model 12-1000) was used to obtain spectral data on two Vertisols and two Alfisols of the Black Belt region of Alabama. The wavelength bands used were 0.45 to 0.52, 0.52 to 0.60, 0.63 to 0.69, 0.76 to 0.90,1.15 to 1.30, 1.55 to 1.75, and 2.08 to 2.35 f.lm. Correlation, regression, and discriminant analyses were used in evaluating soil-moisture, organic matter, and iron oxide effects on the spectral characteristics of the soils. High correlations were found among reflectance and the variables studied. The soils were accurately differentiated based on their spectral properties or physical and chemical properties. A middle infrared band (2.08 to 2.35 f.lm) was most important in imparting variation due to soil moisture. The red band (0.63 to 0.69 f.lm) and a near infrared band (1.15 to 1.30 f.lm) were most important for explaining variability due to the presence of iron oxides. A near infrared band at 0.76 to 0.90 f.lm was the key band in explaining variability due to organic matter content. An increase in soil moisture and organic matter results in a decrease in reflectance spectra, while an increase in iron oxide produces an increase in reflectance spectra in all wavelength bands. A combination of bands from selected portions of the electromagnetic spectrum was used to develop prediction equations for the soil variables.


Data center is a cost-effective infrastructure to store large data volumes and host large-scale service applications. Providers of cloud computing services are deploying data centers worldwide quickly. With lots of servers and switches. These data centers consume substantial quantities of energy, which contributes to high operating costs. Optimizing server and network energy consumption in information centers can therefore decrease operating costs. In a data center, power utilization is chiefly because of servers, network devices, and cooling systems, an effective energy-saving strategy is to consolidate computing and communication into fewer servers and network devices and then power off as many unneeded servers and network devices as possible. A new method of reducing the energy utilization of computer systems and networks in data centers while meeting the requirements of the cloud tenants for quality of service (QoS) is proposed here in this paper.


capitalism's cultural hegemony, its effort (in the words of Printer's Ink (1930), the advertising trade journal) to "manufacture consumers." As systematically as it imposed both Taylorist principles on domestic production and an empire abroad, capitalism created a new dimension of social reproduction: a consumer culture. In several particularly fascinating (and grim) chapters, Ewen describes the successful assault on immigrant resistance to commodity fetishism, and shows the ways in which advertising manipulated the underl$ng shifts in the situations of family, youth, fatherhood, and women during the 1920s in order to create growing numbers of buyers, be they cheerful ar fearful. The parallels with Braverman's Labor and Monopoly Capital are notable, as Ewen is aware. While Taylorism advanced the degradation of labor, advertising introduced an anti-Protestant ethic, one of salvation through spending, possessing, and, pretumably, enjoying. But, as he also notes, this new ingredient in capitalism contained a neo-calvinism of sorts: the craving for commodities was partly induced by the spread of a fear of oneself (one's smells, pores, and the rest). The ever-watchful eye or nose of Others, whose acceptance one had to have, came to replace the divine but frugal grace of an ever-stern Lord. In his extensive last chapter, Ewen indicates that, by the post-World War Two period, the point of production was no longer the locus of capitalism's'contradiclions. If he is harsh on the advertising industry, whose spokespeople have been quick to attack his book, Ewen is also critical of orthodox Marxism. His cultural Marxism or post-Marxism is well worth probing, for he knows both his social history and social theory. People, he says, came to be buyers "not to satisfy their own fundamental needs, but rather to satisfy the real, historic needs of capitalist productive machinery." What the fundamental needs might be, how they are mediated by historical needs, and how people come to sort this out in everyday life, remain the vital questions. Captains of Consciousness has done much to illuminate them.


During the past 50 years, there has been an explosion of new knowledge regarding the biological mechanisms of cardiovascular disease. This knowledge and the emergence of new technology and new pharmacological, interventional, and surgical therapies, coupled with lifestyle changes in the American population, have contributed to a spectacular 60% decline in mortality from coronary heart disease (CHD) and stroke. 1 Since 1965, there has been a dramatic and steady decline in CHD deaths. This marked decrease in the mortality rate for CHD can be attributed in part to enhanced survival in patients with an acute myocardial infarction (MI); highly effective secondary prevention measures in patients who have experienced an ischemic event; improved lifestyles in the population, with some progress in primary prevention of CHD; and advances in medical therapy and the emergence of coronary revascularization. With respect to the decline in CHD mortality from 1980 to 1990, 25% can be explained by primary prevention, 29% by secondary prevention, and 72% by the improvements in medical therapy and revascularization; only 3% is unexplained. 2


Due to the integration functions of inertial energy storage, electromechanical energy conversion and pulse forming, the air-core pulsed alternator has been a promising choice for the pulsed power supply for driving the electromagnetic railgun. The air-core machine has the ability to output a pulse current up to mega-ampere level, and its excitation current also reaches a value of tens of kilo-ampere. Therefore, lots of heat will be produced in an extremely short time during the discharging process. Moreover, the air-friction loss of the machine need to be considered. These will result in a serious temperature rise of the machine, which has a large influence on the machine's performance, especially the repetition output times. In this text, the machine's electromagnetic field is analyzed, a system model consisting of the machine and the railgun is built and the simulation is carried out to investigate the discharge characteristics. The copper loss and the air-friction loss are calculated too. Finally, the machine's temperature rise and its distribution during the acceleration process and the launch process is figured out by the thermal analysis.


'Fuji Kiku-8' and 'Golden Reinders' apples, harvested at commercial maturity, were dipped in calcium chloride (2% w/v) and stored at 1°C and 92% RH for 4 or 7 months under air. The calcium concentration was higher in treated fruit, showing that the treatment was effective in introducing calcium into the tissues. A number of sensory attributes were assessed after cold storage plus 7 days at 20°C by a panel of 9 trained judges. Simultaneously, a panel of 45 consumers was asked to evaluate overall acceptance of samples according to a hedonic scale (1-9). Firmness, soluble solids content and titratable acidity were instrumentally measured in order to assess a possible correlation between parameters instrumentally and sensorily evaluated. For both cultivars, calcium treatment resulted in higher crispness and perceived hardness. Multivariate analysis of data revealed that perception of both crispness and sweetness were the parameters most related to consumer acceptability. Besides, perception of mealiness, which was reduced by calcium applications, appeared to be detrimental for overall consumer acceptability. In consequence, results suggest calcium treatments to be a good practice to enhance sensory quality of cold-stored apples. On the other hand, weak correlations were found between sensorily and instrumentally measured quality parameters, thus indicating the usefulness of sensory tests to assess the effects of postharvest procedures on the quality of produce.


The neurotoxic potential of acrylamide has been known since the very first year of production and use. Later on, the carcinogen action was reconfirmed by experimental research on laboratory animals and epidemiologic studies. Furthermore, toxic effects on the reproductive function have been highlighted, as well as the genotoxic effects. The presence of acrylamide in fried, roasted, grilled and baked foods was discovered in 2002 and enforced the development of new analysis methods and pathways for reducing its formation. The present experiment aims to evaluate hematological modifications after the intake of acrylamide by thermally processed food consumption (French fries and toast) and the consumption of an acrylamide solution 0,1 μg/L, respectively in the case of laboratory animals. The chronic intoxication with acrylamide leads to a decrease of the number of erythrocytes, of the values of hemoglobin and hematocrit, having no important effect on the other erythrocytar parameters.

We construct a new order parameter for finite temperature QCD by considering the quark condensate for U(1)-valued temporal boundary conditions for the fermions. Fourier transformation with respect to the boundary condition defines the dual condensate. This quantity corresponds to an equivalence class of Polyakov loops, thereby being an order parameter for the center symmetry. We explore the duality relation between the quark condensate and these dressed Polyakov loops numerically, using quenched lattice QCD configurations below and above the QCD phase transition. It is demonstrated that the Dirac spectrum responds differently to changing the boundary condition, in a manner that reproduces the expected Polyakov loop pattern. We find the dressed Polyakov loops to be dominated by the lowest Dirac modes, in contrast to thin Polyakov loops investigated earlier.


Introduction: The study was investigated to ameliorative effects of curcumin against E.coli infection induced hypothyroidism in mice. Female mice were E.coli induced intraperitoneal and mitochondrial-targeted curcumin (mt-c) give orally. METHOD: The present investigation was conducted, Mitochondrial targeted curcumin synthesized by covalent linkage of curcumin with lipophilic cation. TPP (1.31 gm) reacted with HBr (350 ml) precursor to obtain lipophilicity. Reverse osmosis (RO) water 200 μl in (5×10) E.coli, and DMSO (2% v/v) were injected in mice by intraperitoneal, after three days 100 μl mt-c (0.12 mg/100 μl), RO water and DMSO were induced in mice for seven days. Control group mice for each experimental setup were given simultaneously RO water and DMSO. RESULT: The thyroid gland weight of mice increased after bacterial toxicity and ameliorate with mt-C its weight decrease, the level of T3 and T4 decerase against bacterial toxicity and ameliorate with mt-C its level increased, Lipid peroxidation and Superoxide dismutase (SOD) increased the level against bacterial toxicity and ameliorate with mt-C its value decreased,where as level of GSH after toxicity decreased and ameliorate with mt-C its value increased. CONCLUSION: The data suggest that effect of mt-c positive against E.coli toxicity on thyroid gland, which could be direct involvement of mt-c on the thyroid gland of mice.


The Trinity Seminar initiated its planned two-year consideration of pneumatology with Kilian McDonnell's paper, "Holy Spirit: Christological Reciprocity, and a Way of Knowing. '" In a set of "discussion paragraphs" McDonnell proposed that in order for Christian theology to be properly pneumatological, the mission of the Spirit must be regarded as being as important as that of the Son. Without a true reciprocity between Christ and the Spirit, trinitarian doctrine collapses. "Being in the Spirit" is the interpretative framework for "being in Christ," and vice versa. Pneumatology cannot be " a tract apart," nor can it function without a trinitarian grammar.


Healthy neonates benefit from a more physiological and gentle transition from placental to pulmonary respiration. 'Delayed' or 'optimal' cord clamping provides this. In this paper, Amanda Burleigh and Christina Uwins describe how Amanda worked towards successfully implementing change on a global stage. Supplemented by a News and Views All4Maternity.com blog, they chart the challenges and triumphs that Amanda faced. They recommend effective ways to encourage staff to embrace innovation and evidence-based practice, rather than resisting it and continuing with what they have always done. Amanda recognises that, as a midwife, it is essential to get a supportive, proactive and resilient senior doctor 'on board' and work together to progress change. Implementing delayed cord clamping in a busy maternity unit can be extremely challenging, but the benefits to babies and parents are enormous, and clearly outweigh the difficulties of gathering evidence, training staff and producing new evidence-based guidance for local practice.


In recent years a wealth of studies have focused on the role of the Hippocampus in spatial learning and navigation, triggered by the finding of place sensitive cells in this area. These cells have been interpreted as being responsible for coding a representation of space [9, 10]. Even though the term place cell suggests that location is the unique determinant of firing of hippocampal cells, there exist several other factors which influence hippocampal activity. Experimental data have shown that the firing of place cells doesn't depend on the heading direction when the animal is foraging freely in an open environment. In contrast, on radial mazes or linear tracks the firing of these cells becomes directionally selective [8, 4]. Furthermore, place directionality also appears in open environments when the animal is constrained to follow the same path between points of special significance [7] We have developed a model of hippocampal place cells, which reproduces both spatial and directional selectivity of these cells. In our model, place cells are intrinsically directional (responding to specific local views), and their directionality is reduced during exploration when the rat is not constrained in the direction of its movements (like in open fields or the centre of mazes). We have modelled changes in the place cell directionality as the result of experience-dependent changes (through unsupervised Hebbian learning) in feed-forward connections from a population coding for specific local views. When the animal is able to explore the same location with different head directions, it allows a single post-synaptic cell to be connected to pre-synaptic cells coding for several local views. Therefore, the directional selectivity of that cell is reduced.


The "Measure" tool in the right-click menu and the "Create Route" button on the ToolBar switches seamlessly to a great circle mode when asked to do long distance tasks. This mainly happens when using these tools in some east-west direction and far away from the equator. The mode kicks in when the difference between the normal, rhumb line and the great circle becomes larger than two nautical miles. This will be some 0.2% to 0.5% of the total distance, depending on latitude and direction. When this happens a clear curve towards the pole will appear.


In this paper we study the use of a new code called Random Diagonal (RD) code for Spectral Amplitude Coding (SAC) optical Code Division Multiple Access (CDMA) networks, RD code is constructed using code level and data level, one of the important properties of this code is that the cross correlation at data level is always zero, which means that Phase intensity Induced Phase (PIIN) is reduced. We find that the performance of the RD code will be better than Modified Frequency Hopping (MFH) and Hadamard code It has been observed through experimental and theoretical simulation that BER for RD code perform significantly better than other codes. Proof -of-principle simulations of encoding with 3 channels, and 10 Gbit/s data transmission have been successfully demonstrated together with Fiber Bragg grating (FBG) decoding scheme for canceling the code level from SAC-signal.


Active machine learning puts artificial intelligence in charge of a sequential, feedback-driven discovery process. We present the application of a multi-objective active learning scheme for identifying small molecules that inhibit the protein–protein interaction between the anti-cancer target CXC chemokine receptor 4 (CXCR4) and its endogenous ligand CXCL-12 (SDF-1). Experimental design by active learning was used to retrieve informative active compounds that continuously improved the adaptive structure– activity model. The balanced character of the compound selection function rapidly delivered new molecular structures with the desired inhibitory activity and at the same time allowed us to focus on informative compounds for model adjustment. The results of our study validate active learning for prospective ligand finding by adaptive, focused screening of large compound repositories and virtual compound libraries.


The invention discloses a synchronous and asynchronous bi-gate thin film transistor (TFT)-organic light emitting diode (OLED) pixel drive circuit and a drive method thereof. The pixel drive circuit comprises a first transistor, a second transistor, a storage capacitor and a light emitting diode, wherein, the first transistor is a synchronous bi-gate TFT and the second transistor is an asynchronous bi-gate TFT. A synchronous bi-gate structure and an asynchronous bi-gate structure are introduced in on the basis of the traditional 2T1C circuit and a precharging voltage and a feedback line are added to the pixel drive circuit. Thus, the maintaining effect to data voltage at a non-gating stage of the storage capacitor is effectively improved. In addition, the threshold voltage compensation of the driving transistors is effectively realized. Thus, the uniformity and the stability of the luminance of displays are ensured. Compared with most pixel drive circuits which are adopted to realize data maintaining and threshold compensation, the transistors, the capacitors and the control lines are saved and the circuit structure is greatly simplified. Thus, the opening ratio and the resolution ratio are increased and the cost is reduced.


We tested the hypothesis that grazing on bacteria would vary between lakcs with differing plankton community structures. Paul and Tuesday lakes (Gogebic County. MI) are respectively dominatcd by piscivorous and planktivorous fish. Consequcntly, zooplankton in Paul are primarily large daphnids, while zooplankton in Tuesday are primarily small cladocerans and copepods. Wc measured flagellate grazing on bacteria using a fluorescent minicqll method, while cladoceran grazing was estimated from the relationship between body length and filtering rate. We predicted that cladoceran grazing on bacteria would bc higher in Paul, and f'lagellate grazing would be highcr in Tuesday. Cladoceran grazing on bacteria was important in both lakes contrary to our initial expectation. Large populations ofthe small cladoceran, Bosmina longirostris, in Tuesday exertcd a grazing pressure (0.18-35 x 106 bacteria I ' h ') approximately equal to that of thc large cladoceran, Daphnia pulex, in Paul (0.34-30 x 106 bacteria I ' h ').Flagellate grazingwas higher in Tuesdayaspredict ed(range: Paul,0.l 6 x l06bacterial rh rlTuesday.0.2-20 x 10('bacterial I h '). Hrrwever, there was not a simple relationship bctwcen total abundance of flagellates and total grazing rates. High community grazing by flagellates occurred when attached choanoflagellates were present. These flagellates had higher ingestion rates than free forms. We find no clear evidcnce that differences in food-web structure between the two lakes influence the process ofgrazing on bacteria. Instead, our results emphasize the significance ofcladocerans and attached tlagellates as consumers of bactena in freshwater ecosvstems.


The present study was aimed to determine the phytochemicals constituents of Salix mucronata Thunb. leaf extracts and their antioxidant activities. Dried leaf powders were extracted with MeOH, MeOH (85%), MeOH (70%) and distilled water. The different extracts were monitored for phytochemical screening. Total phenolic and flavonoid contents were measured by Folin-Ciocalteu and aluminum chloride assays. The antioxidant potential of tested extracts was evaluated using DPPH, ABTS and total antioxidant capacity (TAC) assays. The results showed that, MeOH (85%) extract exhibited high total phenolic and flavonoid contents (TPC=131.39±2.49 mgGAE /g ext. and TFC= 67.69±1.47 mg RE /g ext.). Also, MeOH (85%) extract showed high antioxidant activities (DPPH SC50= 98.76±0.46 (µg/ml), ABTS= 45.83±0.32 mm Trolox® eq. /100 gm extract and TAC= 199.18±2.19 mg equivalent of ascorbic acid /g ext.). On other hand, EtOAc fraction derived from MeOH (85%) extract exhibited the highest antioxidant activity; DPPH SC50= 50.19±0.24 (µg/ml), ABTS= 76.22±1.61 (mm Trolox® eq. /100 gm ext.) and TAC= 249.86±3.74 (mg equivalent of ascorbic acid /g ext.). This study demonstrated that, S. mucronata leaf is a good source of natural antioxidants. Also, there is a high correlation between the total phenolic content and the antioxidant activity.


The two main objectives of this study were to examine the relationship between high school student (9th – 12th) gender and nontraditional career and technical education (CTE) course taking, and the combined effects of gender and program area on estimated future wage earnings for male and female CTE completers. A Midwestern state CTE database (143,510 male and 125,562 female students) designed to fulfill the data collection requirements mandated by the Perkins IV legislation was utilized to answer the two research questions. Findings from logistic regression showed that gender was a statistically significant predictor of nontraditional course taking pattern, with males taking more nontraditional courses than females. Findings from factorial analysis of variance indicated that the effect of gender on estimated future wage earnings measured by the Bureau of Labor Statistics was largely dependent on program area. These findings collectively suggest that although gender pattern in CTE course taking still exists, gender wage gap may be decreasing. Implications of these findings as they relate to educational policy and occupational gender segregation perspective are discussed.

An apparatus for improving the quality of an image of an image sensor is provided to embody a more improved image by adaptively planarizing a color noise generated when a de-mosaicking technique is used in a bayer pattern. A first conversion part converts an RGB color image obtained from bayer data by a de-mosaicking technique into a YCbCr color space. A color noise removing part removes a color noise of Cb and Cr data outputted from the first conversion part. A second conversion part converts the Cb and Cr data outputted from the color noise removing part and the Y data outputted from the first conversion part into an RGB color space. The first conversion part converts the RGB color image into the YCbCr color space by using a matrix and a vector product.


A transition towards green economies takes time and requires new policies and initiatives, and a style of governance that places more emphasis on learning and reflection. This requires, among other things, an ongoing evaluation of policies as they are being implemented. Challenges arise from the involvement of multiple actors, from tensions between accountability and learning, and from the complexity of socio-ecological systems. Consequently the formulation of a workable analytical framework for monitoring and learning is challenging. This paper reports an effort to develop such a framework for monitoring and evaluation of a water quality management plan that is currently being established in the area of Delfland, in the western part of the Netherlands. Insights from evaluation literature, adaptive policy analysis and process management are the basis for this framework.


Through the solvent extraction of copper(II) with the three isomeric chlorobenzoic acids in 1-octanol, it has been shown that the entrance of chloro substituent into the three positions in the benzene ring of benzoic acid results in an individuality in the extraction behavior for copper(II). The dimeric copper(II) chlorobenzoates CU2A4 and Cu2A4(HA)2 were responsible for the extraction with m-chlorobenzoic acid together with the monomer CuA2, while only the monomeric species CuA2 was extracted with o- and p-chlorobenzoic acids. The entrance of chloro group into the ortho position in benzoic acid was found to result in a lowering of both the partition constants of o-chlorobenzoic acid itself and its copper(II) compound. That into the para position has led to a significant decrease in the solubilities of the para isomer and its copper(II) compound in both aqueous and octanol phases.


To prove the conjecture, we consider for any even natural number 2n > 4, with n > 2, the finite sequence of natural numbers
Sm (n) = (si (n)) defined by : si (n) = 2n-pi, with i belonging to set {1,2,...,m}, where pi is the i-th prime number in the finite strictly ordered sequence of primes
 Pm := p1 = 2 < p2 = 3 < p3 = 5 < ... < pm,
where m denotes the number of primes p such that p 2, there exists at least one prime number sr (n) = 2n - pr belonging to the sequence Sm (n), which confirms the result 2n = sr (n) + pr where pr is the r-th prime number of the sequence Pm . This result attests the validity of Goldbach's statement which expresses that:
 every even integer 2n > 4, with n> 2, is the sum of two primes.

Tyre/road noise is the dominant component of overall vehicle noise at medium and high speeds and for cars even at low speeds. Consequently, road traffic noise can be reduced with the proliferation of quieter tyres. One way to achieve this is to give the tyre noise label greater attention
 among tyre and transportation consumers. Hence, the STEER project has evaluated the relevance and performance of the noise part of the European tyre label, looking at how it works in practice, analyzing its uncertainties and suggesting how it can be improved. Its main finding is that the uncertainties
 in the measurement of noise level for the label are too high to be acceptable. This paper focusses on the solutions offered by STEER for an improved tyre label. With four main improvements, the overall uncertainty of the current procedure can be halved. A few possible future strategies to
 increase the market share of quieter tyres have been analyzed and their effects quantified. If the tyre noise label is improved and the market share of quieter tyres can be increased as project STEER proposes, area-wide reductions of up to 3 dB in road traffic noise emissions compared to the
 present situation are possible.


Ancient questions It seems entirely logical that human beings might seek out a fulfilling life that produces positive relationships, good health and a deep sense of meaning. Indeed, ancient cultures the word over have a history of enquiry related to the examination of 'the good life' (Seligman, 1998, p.1). During the 4th Century BC Plato outlined "a general theory of well-ordered human life" (Allot, 2011, p.1165) in his work Republic. From within the Hebrew tradition, Solomon urged his people to turn their "ear to wisdom" and apply their "heart to understanding" (Proverbs 2:2 NIV). This consistent call to wisdom is more relevant than ever in a rapidly changing and increasingly complex world that seeks to understand and facilitate wellbeing for staff and students in an educational context. In search of a better story: Teaching wisdom to build wellbeing in an increasingly complex world


It is well known that the solution to the Einstein Field Equation, gμν, can be either interpreted as the metric tensor itself or the mere gravitational field, their geochronometric correspondence being assured by the Equivalence Principle (e.g. Brown 2005). Within the field interpretation, which allows emphasis on physical effects of gravitation on microphysical constituents of matter, we expose gravitational Lorentz‐Poincare type properties of the relativistic gravitational matter Lagrangian. The Weierstrass parametrization (Johns 2005) of the matter Lagrangian LM in the explicit Lorentz‐Poincare type gravitation model is shown to render it equal to the standard matter Lagrangian —which can be reduced to the proper time invariant (gμνdxμ / dλdxν / dλ)1/2 for the geodesic motion (Stephani 2004)— in GRT. As such the GRT matter Lagrangian can be interpreted to result —following a Legendre transformation— from the energy of the matter fields obtained from Gravitationally Modified Lorentz Transformations (Bro...


When the drivers are driving,they will inevitably come across other cars,acclivities and declivities.When driving at night,strong light glares into the drivers' eyes due to meeting each other halfway with the car lights on and the road reflection,which may cause the drivers to see the road ahead unclearly.In this case the drivers need to manually switch the type of the cars' headlights in time.But sometimes the drivers don't have enough time to accomplish that action,which results in traffic accidents.For this,we designed the Auto Switching System for Vehicle Headlights using the Atmel's ATmega16 microcontroller.It uses the phototransistor as the light intensity detection sensor,and we design the angle detection sensor.If the light shot into the human eye is stronger(weaker) than a certain value,or the angle is more than(below) a certain angle,the system will automatically switch the headlight into near(far) light.


Email of the presenting author: firstname.lastname@example.com The focused ion beam (FIB) ex situ lift out (EXLO) technique for scanning/transmission electron microscopy (S/TEM) specimen preparation was historically the first lift out technique developed [1]. EXLO is well known for its ease, speed, and reproducibility, and is perfectly suited for manipulation of electron transparent specimens to carrier devices developed for in situ S/TEM testing as shown in figure 1a. Using EXLO for manipulation to a conventional carbon coated grid limits the specimen from being further FIB milled and inhibits certain S/TEM techniques. The development of a patent pending grid design and technique called EXpressLOTM allows EXLO and manipulation without needing a carbon film support [2-4]. The specimen is lifted out and manipulated directly to a slotted S/TEM grid surface such that the specimen may be directly analyzed and/or further FIB milled, broad beam ion milled or plasma cleaned. Using this new grid design, a specimen can also be manipulated easily into a backside orientation which avoids curtaining artifacts after further FIB milling [3]. The Xe+ ion plasma FIB (PFIB) is capable of producing electron transparent specimens for S/TEM [5]. The EXpressLOTM method can also be used for manipulating large PFIB prepared specimens as shown in figure 1b where a 50 micrometer long specimen is manipulated to a grid [6]. The 1 micrometer thick PFIB specimen manipulated to the EXpressLOTM grid can be further milled using conventional Ga+ ion FIB or a PFIB. EXLO is now flexible and continues to be fast and reproducible which saves labor and FIB instrumentation time, ultimately reducing the cost per specimen. References: [1] L.A. Giannuzzi, J.L.

A field experiment was conducted at Central Research Station of BAIF Development Research Foundation, Urulikanchan, Pune during 2009–12 to study the effect of planting methods and grass legume combinations on fodder productivity. The experiment was conducted in light gravel soil having initial soil status of 0.35 dS/m EC, 7.36 pH and 0.30 per cent organic carbon. There were four combinations of grasses and legume viz.Cenchurus ciliaris + Desmanthus virgatus, Cenchurus ciliaris + Stylosanthus seabrana, Dichanthium annulatum, + Desmanthus virgatus and Dichanthium annulatum + Stylosanthus seabrana in 1: 1 proportion planted with two planting methods viz. ridges and furrows, and flat bed. Based on four years pooled data, it was observed that green fodder, dry matter, and crude protein yields (763.1, 165.5 and 18.9 q/ha/year, respectively) were significantly increased due to planting perennial grass and legume combination of Cenchrus ciliaris + Desmanthus virgatus in 1: 1 proportion on ridges and furrows. This combination and planting method also had higher net monetary returns of ¹ 55529 ha/year, maize fodder equivalent yield of 308 qha−1 and benefit cost ratio of 2.72. This grass legume production system maintained the soil fertility over a period of field experimentation under rainfed condition of western Maharashtra.


Non-small cell lung cancer (NSCLC) is the most common pathological type of lung cancer. It is a malignant tumor with high incidence rate and mortality rate. After the first-line chemotherapy for advanced NSCLC, some progress have been made in maintenance treatment consists of either chemotherapy or targeted therapy to stabilize the condition, before the drug resistance. However, there is a high incidence of various side reactions of maintenance chemotherapy. Further studies are needed to confirm the survival benefit of the patient with wild type EGFR genes. Traditional Chinese medical treatment on maintenance therapy offers great benefits to patients that include improve quality of life and prolong progression free survival and/or overall survival.


bstract—Trisomy of human chromosome 21 (Hsa 21) caues the pathological characteristics of Down syndrome DS). Little is known about the mechanisms by which trisomy 1 affects the expression of genes on other chromosomes. sing a mouse model of DS, the Ts65Dn mouse, we have erformed mRNA and protein measurements to identify enes on chromosomes not syntenic with Hsa 21 whose exression is affected by the presence of three copies of genes etween loci Mrpl39 and Znf295 on mouse chromosome 16 Mmu 16). We report the upregulation of -catenin, located on ouse chromosome 9 (Mmu 9) in Ts65Dn brain. Using immuocytochemistry on Ts65Dn and control mouse brain tissue, we bserved a striking increase in -catenin expression specifially in the endothelial cells lining the cerebral blood vessels of he Ts65Dn mice. Since -catenin is involved in cell–cell adheion, upregulation of this protein in DS may alter adherens rotein interactions that are involved in the normal functions of ndothelial cells. Elevated -catenin might be responsible for ltered endothelial cell function/s leading to the impairment of rachial flow velocity observed in DS. © 2009 IBRO. Published y Elsevier Ltd.

The study of this research is to measure the electrical conductivity of maghemite nanofluids. Maghemite nanofluids were prepared by dissolving maghemite nanoparticles in water as base fluids. The investigation on electrical conductivity of maghemite nanofluids have been performed at different particle volume fractions and temperatures. The electrical conductivity was measured by a 4-cell conductivity electrode meter. The electrical conductivity of maghemite nanofluids was linearly increased as the particle volume fraction and temperature rises. The highest enhancement of electrical conductivity of maghemite nanofluids due to the particle volume fraction and temperature are 160.49% and 22.55%, respectively. This condition obtained at a particle volume fraction of 2.5% and temperature 60°C. Significant effect of particle volume fraction and temperature were considered.

Significance Observations of planets beyond our solar system (exoplanets) yield uncertain orbital parameters. Particularly in compact multiplanet systems, a significant fraction of observationally inferred orbital configurations can lead to planetary collisions on timescales that are short compared with the age of the system. Rejection of these unphysical solutions can thus sharpen our view of exoplanetary orbital architectures. Long-term stability determination is currently performed through direct orbital integrations. However, this approach is computationally prohibitive for application to the full exoplanet sample. By speeding up this process by up to five orders of magnitude, we enable precise exoplanet characterization of compact multiplanet systems and our ability to examine the stability properties of the multiplanet exoplanet sample as a whole. We combine analytical understanding of resonant dynamics in two-planet systems with machine-learning techniques to train a model capable of robustly classifying stability in compact multiplanet systems over long timescales of 109 orbits. Our Stability of Planetary Orbital Configurations Klassifier (SPOCK) predicts stability using physically motivated summary statistics measured in integrations of the first 104 orbits, thus achieving speed-ups of up to 105 over full simulations. This computationally opens up the stability-constrained characterization of multiplanet systems. Our model, trained on ∼100,000 three-planet systems sampled at discrete resonances, generalizes both to a sample spanning a continuous period-ratio range, as well as to a large five-planet sample with qualitatively different configurations to our training dataset. Our approach significantly outperforms previous methods based on systems' angular momentum deficit, chaos indicators, and parametrized fits to numerical integrations. We use SPOCK to constrain the free eccentricities between the inner and outer pairs of planets in the Kepler-431 system of three approximately Earth-sized planets to both be below 0.05. Our stability analysis provides significantly stronger eccentricity constraints than currently achievable through either radial velocity or transit-duration measurements for small planets and within a factor of a few of systems that exhibit transit-timing variations (TTVs). Given that current exoplanet-detection strategies now rarely allow for strong TTV constraints [S. Hadden, T. Barclay, M. J. Payne, M. J. Holman, Astrophys. J. 158, 146 (2019)], SPOCK enables a powerful complementary method for precisely characterizing compact multiplanet systems. We publicly release SPOCK for community use.


In each case, the point of the irony is to indicate that a proposition the speaker might otherwise be taken to endorse (that the party was fun, the person who took her bag behaved kindly, or Sue is more grateful than she can say) is ludicrously inadequate (here, because of its falsity). A hearer who fails to recognise this will have misunderstood the speaker's ironical intention. A speaker who doubts her hearer's ability to recognise this intention using background knowledge alone can provide additional cues (e.g. an ironical tone of voice, a wry facial expression, a resigned shrug, a weary shake of the head). The ability to understand simple forms of irony is thought to be present from around the age of six or seven, and to be impaired in a variety of conditions including autism, Asperger's syndrome, schizophrenia and certain forms of right hemisphere damage. One of the goals of pragmatics is to describe this ability and thus explain how irony is understood. In classical rhetoric, verbal irony is analysed as a trope: an utterance with a figurative meaning that departs from its literal meaning in one of several standard ways. In metaphor, as in (4), the figurative meaning is a related simile or comparison; in hyperbole, as in (5), it is a weakening of the literal meaning; in meiosis (understatement), as in (6), it is a weakening of the literal meaning; and in irony, as in (7), it is the contrary or contradictory of the literal meaning:

The invention relates to a plant growth accelerant and a preparation method thereof. The plant growth accelerant, which has bright color and stable components, is prepared by taking pyroligneous liquor, a side product obtained by processing wood or waste plant by biological dry distillation technology, as a raw material, sodium erythorbate and propyl gallate added in traces as antioxidant and monopotassium phosphate, ammonium nitrate and different trace elements added in traces as a potentiating agent. The plant growth accelerant has the advantages that the accelerant solves the key problems that pyroligneous liquor is easy to oxidize to generate pigment and cause decomposition of part effective components, thereby making full use of each nutrient component in the pyroligneous liquor.


Wood belongs among the renewable, ecological resources used in many variants of primary and secondary production. The efficiency and effectiveness of using wood resources is, therefore, one of the important factors of sustainable economic development of the society. Each country should strive to maximise the efficiency and effectiveness of the use of raw materials. The aim of the paper is to evaluate the different levels of timber use in international comparison based on the available information of timber resources, production, consumption, import and export in the primary processing in natural and value expressions of wood resources. The results indicate the efficiency of the use of wood resources both for the volume of the total woodworking production and the production value of the woodworking industry in the selected countries.
Keywords: Wood sources, efficiency, added value, comparative analysis.

In previous works ,the estimation of mixing parameters of source signals is based on time frequency representation of two microphone signals. While robustness and source separation efficiency is not good. The proposed system uses complex value filtering that decomposes the real or complex signal into real and imaginary parts in transform domain through Dual tree complex wavelet transform(DTWT). Experimental results shows that Performance excellence of this system is much better than the previous system.


Prostaglandin endoperoxide H synthases-1 and -2 (PGHS-1 and PGHS-2) catalyze the first step in the biosynthetic pathway that produces prostaglandins and thromboxanes. The fatty acid endoperoxide/hydroperoxide substrate, PGG2, binds on the distal side of the heme that forms the peroxidase (POX) site of PGHSs and generates the alcohol PGH2 by cleaving the oxygen−oxygen bond of the 15-hydroperoxide group. The structure of the POX site of PGHS, as with other peroxidases, includes the invariant distal histidine residue His207 and a glutamine, Gln203. We report the first molecular dynamics (MD) simulation of a PGG2 analogue (pseudo-PGG2) bound to the peroxidase site of PGHS-1; pseudo-PGG2 lacks the endoperoxide group and double bonds of PGG2 but is otherwise identical to PGG2. In the MD of the substrate-free state of PGHS-1, a water migrated to the heme active site to become the sixth ligand of the iron, and in time, it hydrogen bonded to other waters, forming chains that extended into the bulk solvent.

Zero-dimensional and one-dimensional ZnO nanostructures were fabricated in this research. ZnO nanoparticles synthesized at different temperatures (55 °C, 58 °C and 62 °C) result in different particle size (11 nm, 22 nm and 36 nm for samples synthesized at 55 °C, 58 °C and 62 °C, respectively) and perform different emission colors under UV excitation. According to the particle size analysis, PL spectra and UV-Visible spectra, larger size ZnO nanoparticles have emission and absorbance wavelengths toward red shifted. Time course PL spectra of ZnO nanoparticles demonstrates the stability of ZnO nanoparticles in ethanol solution is only 9 days after synthesized. Capping a PEG polymer outside ZnO nanoparticle core not only makes ZnO nanoparticles dissolved in water, but also successfully stabilized its PL property to further 22 days. Several sets of growing parameters for growing ZnO nanowires by VLS process demonstrated the growing conditions in our furnace system. The factors that would affect the morphology of as-grown ZnO nanowires were studied. Synthesis of ZnO nanorods by aqueous chemical growth method was successfully achieved. The solubility test result of ZnO nanorods demonstrated in this research is diverse from the one which was reported in a published paper. The purpose of this thesis is to synthesize, characterize and study the potential applications of ZnO nanostructures.
