Continuum robots have been widely used in minimally invasive surgery. However, there are still limitations when applied in narrow cavities, mainly due to the flexibility of the robot arm and the uncertainty of external force contact. In this paper, a force perception method is proposed for the continuum robots with multi-segment structure. The proposed method consists of a shape reconstruction method and a force-position coupling model, where the force-position coupling model considers the effects of multi-segment coupling, friction and external loads. The external load on the end-effector of the robot arm can be estimated by the drive force and the shape of the continuum arm. Simulations and experiments have been carried out to verify the proposed method. Results show that the force perception method is feasible under the normal bending angle of joints.


Turbulence is a common phenomenon in the atmosphere and can generate a variety of distortions in an image. This can cause further image processing tasks to struggle due to lack of detail in the resulting turbulence affected imagery. It is therefore useful to attempt to remove such distortions as a post processing step. However, the development of such algorithms is difficult due to the complex nature of turbulence data acquisition. To alleviate these issues, this paper presents the development of a turbulence simulator that is capable of imparting the effects of a turbulent atmosphere onto clean images and videos. This work also provides a large, publicly available dataset that can be used as a benchmark. The simulator and dataset will be valuable resources in the field of turbulence mitigation. Indeed, the simulator allows researchers to simulate specific turbulent conditions for any application as required; while the dataset provides the ability to make use of turbulent data without the expensive time commitment of simulation.


The escape of xenon from the anti and syn diastereomers of hexacarboxylic-cryptophane-222 in water has been studied by ab initio molecular dynamics simulations. The structures of both complexes, when the xenon atom is trapped inside their cages, have been compared and show no major differences. In addition, the free-energy profiles corresponding to the escape reaction have been calculated with the Blue Moon ensemble method using the distance between Xe and the center of mass of the cage as the reaction coordinate. The resulting free-energy barriers are very different; the escape rate is much faster in the case of the syn diastereomer, in agreement with experimental data obtained in hyperpolarized 129Xe NMR. Our simulations reveal the mechanistic details for each diastereomer and provide an explanation for the different in-out xenon rates based on the solvation structure around the cages.


In this work we present a semi-classical transfer matrix method to study one-dimensional modified quantum transverse-field Ising model. Both average magnetization per spin along the z-direction 〈σz〉 and along the x-direction 〈σx〉 are calculated in this picture. It is predicted that the t > 1 case is the corresponding effective ferromagnetic phase at sufficiently high Hz whereas t < 1 case is an effective paramagnetic phase . Consequently, it is concluded that t = Hz/K = 1, here Hz is the transverse field along the z-axis and K is the coupling strength, which corresponds to quantum ferromagnetic-paramagnetic phase transition. In other words, the same result of the sophisticated quantum field theoretical calculation is predicted unexpectedly in the naive semiclassical picture.


In this paper, we will introduce charm pansystems and provide mathematical models for panweighted field‐network. Various mathematical models of pansystems will be discussed. Some traditional mathematical concepts such as topology space and rough sets theory will be analyzed within this framework.


We describe the results concerning tolerance, response and survival of a program of rescue therapy for primary refractory and relapsed lymphoma combining cyclophosphamide and prednisone with a 96-hour infusion of etoposide, vincristine, and doxorubicin (EPOCH) with cyclosporin A (CsA).


The emergence of smart contracts in blockchain environments allows for a wide spectrum of transaction oriented trusted applications to be developed. The majority of smart contracts are implemented as scripts written in specialized machine interpretable languages such as Solidity. However recent efforts allow for more general purpose languages such as GoLang and JavaScript to be used. It is therefore evident, that smart contract applications will quickly become more complex, and an interesting question that arises is how we can ensure that the smart contract code achieves and complies with the required goals and policies set by the system's stakeholders. In this short paper we outline a model-based approach for the automatic generation and deployment of smart contract code by using extended goal models to capture the tasks and policies set by various stakeholders, and by applying a code generator to produce Solidity code that corresponds to the model.


Businesses operating in turbulent environments must look for ways that will allow them to survive, grow, succeed and increase efficiency. The need to be effective, flexible and innovative is imperative for the functioning and development of modern enterprises. Efficiency is characterized by a wide range of content, as it relates to effects, goals, expenditures and costs in terms of structure and dynamics. Efficiency is an ambiguous and differently interpreted notion of economy, business, process, finance, motivation or logistics. Logistics is an efficiency orientation based on the comprehensive analysis and shaping of the optimum level and structure of outlays and their transformation into costs, where the primary role is to strive for the right level and quality of service and customer service. Considering the effectiveness issue it should be noted that it has not only a real but also a potential dimension. It is therefore important in the systemic sense of the effectiveness of logistics to study not only actual effectiveness but also potential effectiveness. In terms of the subject matter studied, the following basic characteristics of the system are important: stability, adaptability and innovation. Therefore, the article describes the theoretical bases of effectiveness and the place and importance of innovative in efficiency, with particular emphasis on logistics.

SUMMARY

Two varieties of tulip, Golden Harvest and Elmus, of selected bulb weight ranges, were grown in sand culture with different levels of nitrogen, phosphorus and potassium in factorial combination, and at different levels of magnesium.

The effects of nitrogen were dominant, but the levels giving optimal bulb yields differed for the two varieties. Potassium and magnesium had smaller, but significant, effects and there were significant interactions between nitrogen and potassium.

The weight distribution for all daughter bulbs produced from a single planting bulb was discontinuous in certain ranges. Nitrogen had an outstanding influence on the pattern of bulb multiplication, which also reflected a nitrogen/potassium interaction. Responses in weight distribution, as in total bulb production, showed both varietal and seasonal differences.


Introduction: In current days, drug abuse has been acquiring alarming dimensions, configuring an important problem of public health. Among the factors which are responsible for the worsening of the situation is the appearance of new substances which have been altering the practices of use and potentiating its damages. Among these is the product of cocaine paste, popularly called crack, which characterizes by the harm to the user's health and a growing association between its use and the practice of violent and degrading acts, which has been given a lot of attention by the media. Objectives: To describe the circuits, understand the behaviors, the practices and the meanings related to crack consumption among goers of places of high concentration of users and sellers of this drug, in the downtown area of two Brazilian capitals: São Paulo/SP and Porto Alegre/RS. Methodology: A qualitative-ethnographic study was undertaken, with participant observation and register in field journal, having these as a basis for data analysis. Results: In the results, the circuits taken by the users concentrated in specific parts of the central area of both cities were described: Bairro da Luz, in São Paulo, and the region between Rodovia Castelo Branco, Avenida Farrapos and Loteamento Santa Terezinha in Porto Alegre/RS. And also its dynamics: the concentration of people living in the street and their routine activities, specially their relations with state representatives (such as the police and social assistance institutions) are highlighted. The everyday routine of these places is characterized by tense relations and frequent conflicts among the different actors in interaction. According to the research context, most users presented a pattern of compulsive use, in which self-care or any other activities were in second place in relation to the frenetic drug use. However, some subjects who didn't present this use or dependency pattern were identified, employing several strategies of self-control in the use of the drug and also regarding survival. Conclusion: We point to the importance of observing factors such as the history of the researched region, public policies, economic issues, and the absence of social and public health investments for the understanding of the appearance and permanence of the researched circuits. We suggest that the high degree of degradation of those regions wouldn't be a consequence only of the people and activities performed in the place, but mostly, of the urban process that generated such social frame. We also point to a strict relation between the socio-cultural-historical context of the subjects and their crack consumption pattern, indicating the existence of internal differences in the studied group, which distinguishes users with a minimal degree of structural and ethical organization from those for whom the obtaining and consumption of crack acquires priority regarding any other activities or relations of their daily life. Descriptors: use of crack, homeless, ethnography, public health.


This paper assembles evidence to discuss a mechanism that may contribute to the positive Cloud to Ground (+CG) lightning presence over the US Great Plains (GP). Data from EPA reveal maximum ammonium (NH4+) concentrations in precipitation over the entire US are observed over the GP. Laboratory experiments show NH4+ favors graupel's positive charging, a key-process for +CG enhancement. This study speculates that the spatial coherency between the NH4+ concentrations and the enhanced presence of +CG may not be a coincidence but relate to a physical mechanism that acts independently from the established thunderstorm charging processes.

Population aging is taking place in Russia: the proportion of older people in the total population is rising, which leads to an increase in the demographic dependency ratio. Sanctions in the long term can have a significant negative impact on the growth rates of the Russian economy, which have shown instability in recent years, and in some periods have taken negative values. These trends determine the relevance of this study. The purpose of the work is to predict the demographic dividend in Russia in the period up to 2036, that is, to predict the impact of population aging on economic growth. When forecasting the future dynamics of the demographic dividend in Russia, we identified two effects: the effect of the 2019 pension reform (a phased change in the retirement age) and the effect of the COVID-19 pandemic. According to our calculations, both the pension reform and COVID-19 have a positive effect on the demographic dividend in Russia (as the boundaries of working age are expanding, and COVID-19 supermortality was more observed among the elderly, which changed the share of the working-age population). At the same time, the effect of the pension reform is much stronger than the effect of the pandemic.


Several new iridium complexes with the dibenzo-24-crown-8 substituted 2-penylpyridine (ppy) ligand have been synthesized and characterized. These iridium complexes emit green light with a high photoluminescence quantum yield ranging from 0.56 to 0.63 and exhibit good thermal properties. The complexes were incorporated into phosphorescent polymer light-emitting devices (PLEDs) using soluble poly(N-vinylcarbazole) (PVK) as the host and the resultant iridium complexes as dopants. High-efficiency green electrophosphorescence was observed, with peak emission at about 520 nm. Among these devices, the PLEDs with G3 as the dopant displayed the best EL performances. An external quantum efficiency of 10.92% and a luminous efficiency of 29.6 cd A−1 were obtained at 537 cd m−2.


We study the influence of an additional uncontrolled (stray) magnetic field upon the measurement of long-range spin-spin interaction strength of two spin-1/2 valence electrons bound in two separate ions at well-defined distances from each other. This stray field, which is neither perpendicular nor parallel to the line connecting two ions, could appear due to the Earth magnetic field, or, due to the slight angular misalignment between the applied magnetic field and the line connecting two ions. It is found that the presence of the stray magnetic field plays an important role in the dynamics of the spin-states of two electrons. If neglected in the analysis, moreover, such a stray field may affect the measurement of the spin-spin interaction strength, especially at smaller inter-spin distances.


A probabilistic comparison algorithm is presented which requires O(f log n) bits to be transmitted to identify the corrupt pages in a file (where n is the number of pages and f is the maximum number of pages that could be corrupted), which improves on previous results on the growth of communicated bits as functions of both n and of f. If both copies compared are corrupt, only twice the number of bits is required as for the previous case. Further, if multiple copies are used for comparison, then the product of the number of copies times the number of bits sent from each of these copies to the comparison site grows as O(f log n). A lower bound which establishes the optimality of the algorithm to within a constant factor is provided.<<ETX>>


Urban areas modify boundary layer processes through the creation of "urban heat islands" or UHI. In cities, natural land surfaces are replaced by artificial surfaces that have very different thermal properties (e.g. heat capacity, specific heat, and thermal inertia). Such surfaces are typically more capable of storing solar energy and converting it to sensible heat. As sensible heat is transferred to the air, the temperature of the urban air tends to be 2-10 degrees higher than surrounding non-urban areas (fig, 1).


To design a home service robot, the Turtlebot robot based on ROS platform is used to achieve the autonomous navigation and obstacle avoidance functions. The result is shown in simulation experiment. During the experiment, to complete SLAM mapping, the Gmapping algorithm is applied. On the other hand, the Dijkstra algorithm is used for global path planning, and the dynamic window algorithm is used for local path planning. Both of them are used to realize the autonomous navigation function. By carrying the depth camera Astra, the robot can autonomous navigate and avoid obstacles in the indoor environment. In addition, by writing scripts, the SLAM mapping process, which originally required manual control, has also been improved to autonomous SLAM without manual control, making it more convenient in practical applications.


We demonstrate and characterize two coherent phenomena that can mitigate the effects of laser phase noise for electromagnetically induced transparency (EIT): a laser-power-broadening-resistant resonance in the transmitted intensity cross correlation between EIT optical fields, and a resonant suppression of the conversion of laser phase noise to intensity noise when one-photon noise dominates over two-photon-detuning noise. Our experimental observations are in good agreement with both an intuitive physical picture and numerical calculations. The results have wide-ranging applications to spectroscopy, atomic clocks, and magnetometers.


Critical thinking skills are 21st century life skills that are very necessary for life. The purpose of this study is to analyze the level of critical thinking skills of students, and how influential learning motivation is on students' critical thinking skills. The research method used is mixed methods with explanatory sequential strategy. The sample of this study were students in grade V SD Jagalan. Data collection is done by the method of tests, interviews, observations, and documentation. The results of this study indicate that the critical thinking skills of students at SD Jagalan reach an average score of 67. Indicators of critical thinking skills from the highest to lowest values are interpretation, analysis, inference, and explanation. Based on the results a simple regression analysis shows the value of the correlation or relationship that is equal to 0.715. The influence of learning motivation on critical thinking skills is indicated by the coefficient of determination of 51.2%, while the rest is influenced by other variables. So, it can be concluded that there is an influence of learning motivation on critical thinking skills. The higher the motivation of students to learn, the higher their critical thinking skills.


Author(s): Rengert, Zachary David | Advisor(s): Bazan, Guillermo C; Nguyen, Thuc-Queyn | Abstract: Biotic-abiotic interfaces play crucial roles in bioelectrochemical systems, where the transport of electrons across membranes to or from an electrode is a key challenge which limits device performance. In electrogenic bacteria, this process is assisted by transmembrane proteins which utilize redox centers to shuttle electrons to extracellular electron acceptors. However, electrogenic bacteria are quite rare in nature and imparting electrogenic phenotypes to broad classes of bacteria represents an understudied strategy, especially with respect to real world applications of bioelectrochemical systems.Drawing inspiration from the naturally occurring electron transporting proteins found in Shewanella oneidensis, we designed a redox active conjugated oligoelectrolyte (COE) which mimics the properties of these proteins in a small organic molecule, DSFO+. The properties of DSFO+ allow it to spontaneously intercalated into a lipid bilayer, have a redox potential that is biologically relevant, and catalyze transmembrane electron transfer in a non-toxic manner. The design, synthesis, and characterization of DSFO+ with relevant comparison to previous COE architectures will be discussed in detail . The ability for DSFO+ to catalyze transmembrane electron transfer in wild type and mutant strains of Shewanella oneidensis lacking key transmebrane redox proteins will then be discussed. These results afford the description of DSFO+ to be akin to a synthetic protein prosthetic. The design of a 2nd generation of redox active COEs bearing two redox centers will then be discussed and characterization of their electrochemical properties will be investigated. Intermolecular interactions play a large role in the observed electrochemical response of these materials and these effects will be deconvoluted from single molecule properties. Fluorinating the semiconducting backbone modulates electochemical properties, allowing for studying the effect of redox potential on bioelectrochemical performance with minimal change in COE structure. Preliminary results using our 2nd generation redox active COEs in bioelectrochemical devices will be presented.In the last section, the interaction of non-redox active COEs is investigated with model lipid bilayers in the form of liposomes. Cationic and anionic COEs were used to stain liposomes containing neutral or anionic lipids. Electrostatic interactions were found to play a large role in governing the favorability of COE intercalation and the amount of COE incorporated into a liposome was found to closely correlate with changes in the surface potential of the liposome. The mole percent of COEs in model systems were found to be much lower than what was previously found in living systems, hinting at the possibility of more complex COE-cell interaction than what can be accounted for in a simple membrane intercalation model. These results indicate that COE intercalation is governed not only by solubilization of the hydrophobic core of COEs in the lipid bilayer, but that COE-COE and COE-lipid electrostatic interactions play an important role in governing the favorability of COE intercalation.


Selection of the two catchments in this study: I find the selection of the two catchments a bit problematic. Mainly, the two catchments vary in several aspects besides the so-called aridity fraction (e.g. size). This makes comparison difficult. Furthermore, one of the catchments reports zero-flows. Here it is important to note that the used model variants are by design not able to simulate zero-flows. The occurrence of zero-flows also makes the use of log-transformations for the computation of performance measures challenging.


High definition video application has drawn a lot of interest both from academy and industry. The relevant latest video coding technology, H.265/HEVC has been a promising area for video steganography. In this paper, we present a novel and efficient video steganography method based on transform block decision for H.265. In order to improve the visual quality of carrier video, we analyze the embedding error of data hiding with modifying partitioning parameters of CB, PB and TB, and modify the transform block decision to embed secret message and update corresponding residuals synchronously. In order to limit embedding error, we utilize an efficient embedding mapping rule which can embed N (N>1) bits message and at most modify one bit transform partitioning flag. Our experimental results show that the proposed method can achieve better visual quality, larger embedding capacity and less bit-rate increase than state-of-the-art researches.


Targeted by policies on sustainable energy, ordinary men and women are also engaged in the routines and concerns of everyday life. This paper asks to what extent French and Norwegian households link global warming to their own electricity use. Furthermore, we study people's rationales for selecting renewable sources and reducing electricity consumption at home. Empirical material was collected in France and Norway. We draw on a practice theory framework. The purpose of the paper is to use a comparative analysis for highlighting important aspects of the electricity cultures in each country, thereby accounting for why the French and the Norwegians respond to appeals for sustainable energy in the ways they do. The results show that people in both countries tend to regard their own electricity use as disconnected from global warming. This is partly due to the high share of non-fossil power production in both countries, but we also suggest that certain denial mechanisms reinforce the idea that electricity consumption is disconnected from environmental challenges. The French respondents relate to the state-owned supplier EDF. They are preoccupied with physical and financial risks and regard electricity as a necessity. Conversely, the Norwegians value electricity in itself as a non-problematic good to which they think they have a claim as Norwegian citizens. Although the cost of electricity has an equal share of the household budget in both countries, the French practice a savings culture to a much greater extent than Norwegians do.


PURPOSE: A battery uses a negative electrode for a battery with high safety against the change of cycle due as time passed, thereby having excellent cycle performance. CONSTITUTION: A battery comprises a negative electrode (1) on which a negative active layer (1B) containing a natural graphite-containing negative active material is formed on at least one surface of a negative current collector (1A); and an electrolyte. The thickness of the negative active material layer is 50-100 micron per one surface of the negative current collector. The orientation degree calculated by the peak intensity of (002) carbon plane measured by X-ray diffraction/the peak intensity of (110) carbon plane is 100-500, from the negative current collector up to the 1/2 thickness of the negative active material in the surface direction of the negative active material layer.


Diabetes mellitus (DM) is a chronic endocrine metabolic disorder that can increase the incidence of infertility. Excessive production of reactive oxygen species (ROS) can trigger oxidative stress reactions and reduce antioxidant content. The increase of ROS can exert an impact on the endoplasmic reticulum (ER) stress conditions and inhibit the steroidogenesis of the testes. The objectives of the current study were to determine the effect of chlorogenic acid (CGA) as an antioxidant in reducing ER stress conditions (mRNA expressions of GRP78, XBP1s), and to increase steroidogenesis (mRNA expressions of 3β-HSD and 17β-HSD) in the testis of DM rats. A total of 24 rats were randomly divided into six groups, namely: control group, DM1.5 months, DM2 months, and DM group were treated with CGA with three different doses (12.5 mg/kgBW, 25 mg/kgBW, and 50 mg/kgBW), respectively. Testicular tissue was isolated for examination of GRP78, XBP1s, 3β-HSD, and 17β-HSD mRNA expressions using RT-PCR. In the CGA1 group, GRP78 mRNA expression level was lower than in the DM2 group and was statistically different (p=0.021). XBP1s mRNA expression in the CGA1 group was lower and significantly different when compared to the DM2 group (p=0.018). The mRNA expression of 3β -HSD in the CGA1 group was higher than that in the DM1.5 and DM2 groups, which were statistically significant with p=0.000 and p=0,008. The comparison of 17β - HSD mRNA expression in the CGA1 group was higher than the DM1,5 and DM2 groups with p=0.013 and p=0.012. Administration of CGA at a dose of 12.5 mg/kgBW can reduce ER stress conditions and increase testicular steroidogenesis in DM rat models. These results were seen based on low GRP78 and XBP1s mRNA expressions, and high 3β-HSD and 17β-HSD mRNA expressions after CGA administration.


Essential oils from renewable plant sources are important considerations for environmentally benign botanical pesticides. In this work, the leaf essential oils of four species of Vitex (Lamiaceae) have been collected from north-central Vietnam, analyzed by gas chromatographic techniques, and screened for mosquito larvicidal activity and molluscicidal activity. Vitex ajugifolia and V. pinnata essential oils were dominated by sesquiterpenoids (97.8% and 95.8%, respectively). In contrast, however, the essential oils of V. trifolia subsp. litoralis showed monoterpenoids to be dominant. The essential oils of V. trifolia subsp. trifolia also showed abundant monoterpenoids (38.4% and 68.0%), but also included (E)-β-caryophyllene (15.8 and 14.5%). Vitex pinnata essential oil showed excellent larvicidal activity against Aedes aegypti and Culex quinquefasciatus. Both V. trifolia litoralis and V. trifolia trifolia demonstrated notable molluscicidal activities against Gyraulus convexiusculus and Pomacea canaliculata. The research results suggest that essential oils of Vitex species might have potential to be used as natural pesticides.


Exciton-LO-phonon scattering in a high-quality V-shaped AlGaAs/GaAs quantum wire grown by flow rate modulation epitaxy is investigated using temperature dependent photoluminescence excitation spectroscopy (PLE). The linewidth of the ground state PLE peak is found to be almost independent of temperature at least up to 250 K, indicating a drastic suppression of the exciton-LO-phonon scattering in QWRs. The Coulomb field-induced reduction of oscillator strength in the continuum is considered as an important reason responsible for the observed exciton-LO-phonon scattering suppression.


In this paper we compare the price of an option with one year maturity of the German stock index DAX for several volatility models including long memory and leverage effects. We compute the price by applying a present value scheme as well as the Black-Scholes and Hull-White formulas which includes stochastic volatility. We find that long memory as well as asymmetry affect the Black-Scholes price significantly whereas the Hull-White price is hardly affected by long memory but still by including asymmetries.

The presence of prominent inclusions suggestive of secretory activity in neurons of opisthobranch molluscs has attracted the attention of a number of investigators. €3. Scharrer ('35, '37) described as neurosecretory special nerve cells in the nudibranch genera Tethys, Aeolis and Doris, and in the tectibranch genus ApZysia. Tuzet et al. ('57) later verified the presence of neurosecretory cells in Aeolis. Other reports of neurosecretion in tectibranchs have been made by Lemche ('55, '56) in Cylichna and by Gabe ('53) in a number of species. Other studies have also been concerned in part with the general cytology of Aplysia neurons (e.g., Eales, '21; Schreiber, '29, '30; Arvanitaki and Tchou, '42; Tchou, '42; Chalazonitis and Arvanitaki, '51, '56; Winkler, '56; Arai, '60; Batham, '61; Hughes and Tauc, '61; Bullock, '61). Rosenbluth ('63) has recently completed a study of some ultrastructural aspects of the visceral ganglion of Aplysia caZifornica. The purpose of the present investigation has been to study the nature of the neuronal inclusions in the cerebral and visceral ganglia of Aplysia californica (Cooper, 1863) with special attention to the problem of neurosecretion.


The article presents the results of theoretical and empirical research aimed at revealing in a holistic and systematic manner the psychological features of professional activity of operators of unmanned aerial systems of tactical classes. The authors established that such professional activity is objectively complex, clearly regulated, multifunctional, comprehensive, has an individual and collective nature of work, and contains elements of extremity in performing typical tasks not only in combat but also in everyday conditions, which is due to the presence of a few inherent stress factors which negatively affect its subject. The study proves that the performance of a wide range of professional tasks by an operator of unmanned aerial systems of tactical classes places high demands on his physical endurance, emotional balance, ability to concentrate and distribute attention, ability to switch from one task to another, requires a high level of professional competence, nervous and mental stability, rapid adaptation to activities in difficult conditions, moral normativity of behaviour, focus on achieving professional mastery, motivation for professional success, responsibility, personal organization, self-discipline, high level of involvement of volitional processes, ability to maximum mental productivity in conditions of emotional and physical tension. The work carried out allowed us to establish an array of individual psychological characteristics of the specialist under study, which are professionally important, and the main contraindications for a person to serve as a UAV operator in the Armed Forces of Ukraine and other military formations. The areas of applied application of the presented research material for a more complete practical implementation of the psychological component of the process of professional training of tactical UAV operators are presented.


We report calculations of the domain wall entropy for the bimodal two-dimensional Ising spin glass in the critical ground state. The $L\ifmmode\times\else\texttimes\fi{}L$ system sizes are large with $L$ up to $256$. We find that it is possible to fit the variance of the domain wall entropy to a power function of $L$. The data were obtained using an algorithm that works exactly in the ground state. The integrity of the floating point arithmetic was rigorously checked against exact results for correlation functions and some disorder realizations were run in arbitrary precision as necessary. Nevertheless, in spite of the excellent integrity of the results, the quality of the data distributions are unsatisfactory with large $Lg96$. Consequently, it is not possible to reliably determine the fractal dimension of the domain walls.


The states and Indian tribes have fought bitterly over water rightsfor nearly a century. Most of this conflict tookplace in courtrooms, but in recent years, states and tribes have been attempting to resolve their diferences through negotiated water settlements. This article utilizes the literature and theory on alternative dispute resolution to identify six advantages that are expected to accruefrom negotiations. It then assesses the extent to which Indian water settlements have produced these results.


Children's behavioral disorders are prevalent and disabling disorders that for teachers, parents and children themselves can make many problems associated with many social problems. The aim of this study was to investigate the relationship between parenting style and behavioral disorders in preschool children in the Shadegan city. The method used in this study, is the correlational (descriptive). The sample consisted of 40 mothers of preschool children in Shadegan city with an available sampling have been selected. To measure the variables in the study Connors behavioral disorders questionnaire (parent form) and Bamirind parenting questionnaires used. To analyze the data, Pearson correlation analysis used. The results showed that there is no significant relationship between parenting style (permissive and logical authoritative) and behavioral disorder at 0.001. In addition, there is significant relationship between the style of parenting (authoritarian) and behavioral disorder at 0.001. The ways in which parents are educating their children, play an essential role in providing mental health of their children, in light of the healthy relationship that the child's needs and to provide the satisfaction of knowing they initiated.


This is the second recent paper addressing the question: is vitreous biopsy a useful procedure in the diagnosis of uveitis? (I reviewed the previous paper (Davis et al., Am. J. Ophthalmol. 2005:140:822–829) in last month's Journal Watch column). In the present paper, the authors reviewed the medical records of 62 patients who had vitreous sampling performed between 1997 and 2003. The patients represented a variety of clinical diagnoses. Approximately two thirds were suspected of having bacterial or viral intraocular infection. The remainder were felt to have potential malignancy. Sample tests included culture, cytology, and PCR, if the patient was believed to have a viral retinitis. The original clinical diagnosis was confirmed in 37 of 59 patients (62.7%). Five patients with a clinical diagnosis of noninfectious inflammation were misdiagnosed. The yield on late onset exogenous endophthalmitis was fair with diagnoses made in approximately one half the cases. The authors had remarkably good yield on intraocular lymphoma, confirming the diagnosis in four of four suspected cases. Yield was also excellent for viral retinitis and ocular toxoplasmosis, with confirmation in all cases. The authors were also able to confirm four of five fungal endophthalmitis cases. A total of 13 cases of idiopathic inflammation, however, only yielded appropriate diagnosis in two cases. Both of these were due to Staphylococcus epidermidis. In seven of the 59 patients, the vitreous sampling provided critical new information that altered the management of the patient. In three cases of idiopathic uveitis, bacterial sources were found, leading to treatment with antibiotics and improvement in patient outcome. One case initially diagnosed as viral retinitis was ultimately diagnosed as ocular toxoplasmosis, and one case of presumed metastatic disease was found to be intraocular lymphoma. Consistent with the Davis et al. report, vitreous biopsy was found to have a high diagnostic yield when pretest probability was high. However, even in this situation, vitreous biopsy provided unexpected and clinically relevant information in over 10% of cases. Vitreous biopsy had poor yield, however, in patients with suspected late onset bacterial endophthalmitis, and had minimal utility in patients with idiopathic uveitis unresponsive to treatment. Thus the present study does not support the use of vitreous biopsy in cases where clinical suspicion for known entities is low.


Abstract A reading is presented of The Namesake and The Tree Bride as diasporic novels that transnationalise the host culture by inscribing the ethnicity and history of Bengal on to the cultural topography of America. This interpolation is contextualised both in terms of the 'Bengal connection' — the now occluded saga of Bengal's rich commercial and intellectual contacts with New England from the seventeenth to the nineteenth centuries — and the changing paradigms of immigrant socialisation from the melting pot to multiculturalism and beyond. The inference drawn is that the non-Eurocentric and non-Atlantic 'Bengal connection', which may be taken as emblematic of other such strands in American society, not only troubles monologic myths of 'Americanness', but simultaneously interrogates the sufficiency of the 'Atlantic' template as the marker of a multi-ethnic nation. A suggested alternative is Tagore's 'vernacular nationalism' that admits intrinsic otherness as integral to its conception of national identity.


The ancient Eratosthenes experiment concerning the earth's circumference offers the opportunity of an inquiry-basedrevival in today's science classrooms: A multinational European science education initiative (acronym: OSR)introduced this experiment as a hands-on basis to extract the required variables and to exchange results withclassroom peers across two continents, including Finland in the North, via Poland and Serbia to Greece and Egypt inthe South. The aims behind focused on typical science requirements in classroom approaches such as measurementspreads of scores, translation of one score into its context as well as to solve a complex scientific question withsimple hands-on results when unveiling nature's hidden principles. Within the scope of this present study, 2180students from 89 schools in 5 different countries (Finland, Poland, Serbia, Greece, Egypt) completed theEratosthenes experiment on the same day. Working groups of up to four students collected the measurement scoreswithin their school sites which by selection covered about 30 degrees of latitude. The analyses clearly show moreaccuracy in the scores as more distant the measurement sites are located (within Greece: 17.6% error; Greece –Finland: 1.3% error). Recommendations for school implementations as well as its potential in experimental scienceclassrooms are discussed in detail.

Abstract This paper puts the spatiality of migration, and more specifically post-migration connections, centre stage. It explores the distances confronted by migrants as they stay connected with their pre-migration lives, recognising that these distances are recalcitrant, asymmetrically governed spaces. Indeed, migrants can be understood as experts in the navigation of international space and 'the tyranny of distance'. Inspired by recent work on urban and translocal infrastructures and taking the empirical example of migration infrastructures in the lives of Poles and Zimbabweans in the UK, looking particularly at the materiality and logistics of sending things back, this paper builds new discussions about migration which take the spatial, physical and grounded elements of migration and translocalism more seriously.


Simple Summary Fluorescence confocal microscopy (FCM) is a novel micro-imaging technique providing optical sections of native tissue. The method is increasingly used for the routine diagnosis of tumors and inflammatory lesions of the skin and shows promising results for the diagnosis of other organ tumors. Very few publications exist about examinations of liver tissue thus far. In this study, we compare findings of FCM-examinations of biopsies and surgical specimens of the liver with the final diagnoses from conventional histology. Abstract Ex vivo Fluorescence Confocal Microscopy (FCM) is a technique providing high-resolution images of native tissues. The method is increasingly used in surgical settings in areas of dermatology and urology. Only a few publications exist about examinations of tumors and non-neoplastic lesions of the liver. We report on the application of FCM in biopsies, surgical specimens and autopsy material (33 patients, 39 specimens) of the liver and compare the results to conventional histology. Our preliminary examinations indicated a perfect suitability for tumor diagnosis (ĸ = 1.00) and moderate/good suitability for the assessment of inflammation (ĸ = 0.4–0.6) with regard to their severity and localization. Macro-vesicular steatosis was reliably detected, micro-vesicular steatosis tended to be underestimated. Cholestasis and eosinophilic granules in granulocytes were not represented in the scans. The tissue was preserved as native material and maintained its quality for downstream histological, immunohistological and molecular examinations. In summary, FCM is a material sparing method that provides rapid feedback to the clinician about the presence of tumor, the degree of inflammation and structural changes. This can lead to faster therapeutic decisions in the management of liver tumors, treatment of hepatitis or in liver transplant medicine.


Seawater electrolysis has the potential to be a more sustainable means of hydrogen production compared to conventional water electrolysis which relies on highly pure water. This is particularly true for arid coastal regions with access to seawater and ideal conditions for harvesting solar and wind energy, but where fresh water is already scarce.[1] Seawater electrolysis is challenging due to the large concentration of chloride ions, which can be detrimental to electrocatalyst stability. Furthermore, the presence of chloride ions allows the chlorine evolution reaction (CER) to compete with the oxygen evolution reaction (OER) at the anode. Although Cl2 is of industrial value, global hydrogen production already exceeds chlorine production, and demand for hydrogen is projected to grow more rapidly. Additionally, since Cl2 is toxic and harmful to the environment, implementing seawater electrolysis is simplified if pure oxygen is produced and can be safely vented to the atmosphere.
 Our group has shown that ultrathin semi permeable oxide overlayers can be designed to selectively transport reactants to the active catalyst at the buried interface.[2-3] Importantly for seawater electrolysis, the oxide overlayer selectively rejected chloride ions while allowing for water transport.[4] Thus, the oxide overlayer acts as a membrane, and the composite material can be referred to as a membrane coated electrocatalyst (MCEC). An additional advantage of the MCEC architecture compared to conventional electrocatalysts is enhanced stability.[5] This makes MCECs particularly attractive for stable and selective OER in seawater. This work describes how MCECs can (i) improve catalyst stability and (ii) enable selectivity for OER over CER by impeding transport of chloride ions to the catalyst at the buried interface. This work explores the fundamental relationships between chloride ion transport through different oxide overlayer materials. This knowledge is then applied to prepare MCECs supported on high surface area porous electrodes.

A multiscale approach for analyzing in vivo magnetic resonance spectroscopic imaging (SI) data is described in this paper. With this method, fitting is performed at multiple spatial scales in a coarse‐to‐fine order. Results obtained at one scale are used as prior knowledge in fitting spectra at the next scale. The multiscale approach was validated with simulated data and demonstrated with proton SI datasets of the human brains. The results showed that this method improved the robustness and efficiency of the fitting and facilitated the automatic analysis of in vivo SI data.

The study of crop genetic diversity has received attention in recent decades to develop new varieties adapted to harsh environmental conditions. Pea ( Pisum sativum L.) is one of the main sources of legumes due to its higher protein content. In the present investigation, 25 accessions of Turkish and Tunisian peas were characterized by fifteen ISSR markers in order to preserve this germplasm and develop new high-performance varieties. Means of diversity indices, Polymorphism information content (PIC), resolving power, marker index, major allele frequency and Shannon index were 0.70, 5.56, 3.20, 0.89 and 0.35, respectively. The analysis revealed a higher polymorphism (84.15%). The coefficient of similarity Jaccard varied from 0.45 to 1 exhibiting a greater genetic variety. The patterns detected by the cluster analysis, divided the 25 pea genotypes into three main groups. These findings were in agreement with the population structure which divided accessions into three main populations. Therefore, this paper has clearly shown the usefulness of the ISSR markers to provide a great degree of polymorphism for peas. The information collected from this work can help pea breeders to implement a selection program that improves the distribution of this crop in Turkey and in the arid regions of Southern Tunisia.

The experimental results on the gas temperature measurement in the active zone of streamer discharge in air at the atmospheric pressure are presented. The gas temperature value was obtained by the optical method for measur-ing the relative intensity of the rotational lines for the radiation of the second positive (II+) system of molecular ni-trogen, transition bands (С3Пu(0)→B3Пg(0)). It was found that in discharge gap d = 8 mm, depending on the ap-plied voltage (in the range of 6.1…7.8 kV with a step of 0.2 kV), the gas temperature varied from 609 to739 K. The unevenness of the gas temperature change in the active zone of discharge with the increase in the applied voltage is shown. This may be related to the possible changes in the rotational state of nitrogen molecules upon excitation of their electronic state by electrons.


In order to solve the problem of error rate caused by pose and illumination variation, the sparse statistical deformable model is used to reconstruct the 3D face shape. By using the method of spherical harmonic quotient image, estimation of the original input image light properties, the generated model standardized posture and illumination reconstruction, the original input image due to pose and illumination recognition error caused by the different solution. Experimental results show that the proposed method can effectively improve the recognition rate of 3D face.

The main topic of this note will be the application of homogenization theory to the study of phase transitions problems in composite media. The starting point of the research (see Section 2) is a result of Γ-convergence obtained by L. Modica and S. Mortola in 1977 ([MM77]), and later on rivisited by Modica [M87] in terms of Van der Waals Cahn Hilliard theory of phase transitions. In those two papers the authors study, with Γ-convergence techniques (see [DGF75], [DM93], [B]), the asymptotic behaviour of a family of functionals of the type

With the rise of populist regime and its implicative tendencies around the world, we need to understand that institutional delegitimization is on the rise. The third pillar of democracy, i.e. the executive, has steadily shown a dualistic reaction of reconciliation and antagonism alongside systematic changes in perception about populism. The case studies on the populism are a preliminary analysis of the political conditions which give rise to populist leaders and their regime, it actually hints at the tumultuous conditions which are brought from its inceptions like in cases of Central European, Asian and Latin American countries.


The paper presents the results of a series of in-situ tests carried out on two masonry arches, one unreinforced and the other reinforced with SRG (Steel Reinforced Grout). The arches are built adopting a peculiar construction technique using common Italian bricks with dimensions 250 × 120 × 55 mm3 and 10 mm thick mortar joints. One of the two arches has been reinforced with an SRG material constituted by an inox grid embedded into a layer of lime mortar, whereas the second one is maintained unreinforced for comparison purposes. The experimental set-up is designed to apply an eccentric vertical load placed at ¼ of the span in a series of loading and unloading cycles up to the failure. The numerical analyses have been performed using a sophisticated heterogeneous micro-modeling technique, where bricks, mortar joints and the strengthening have been modeled separately. Finally, the numerical outcomes have been comparatively assessed with respect to the experimental results and the crack patterns obtained at t...


Background: Alopecia Areata (AA) is a common autoimmune disease leading to non-scarring hair loss. Previously, AA had been noted following various vaccinations including influenza virus, hepatitis B virus, herpes zoster virus, human papillomavirus, Japanese encephalitis, and Clostridium tetani. During this pandemic, AA following SARS-CoV-2 vaccine injection was rarely reported

Objective: We report a case of diffuse AA and its trichoscopic findings following COVID-19 mRNA-1273 vaccination.

Method: A trichoscopic examination of the scalp was performed. An English literature review through PubMed and an online search of the Vaccine Adverse Event Reporting System (VAERS) database were conducted.

Finding: Only 20 patients of AA following SARS-CoV-2 vaccination were reported in the English literature. Black dots and broken hair were the most common features, followed by yellow dots and exclamation mark hairs. The VAERS database showed 77.8% were associated with the BNT162b2 vaccine and 20.9% with the COVID-19 mRNA-1273 vaccine, respectively.

Conclusion: A rare case of AA and its trichoscopic findings following COVID-19 mRNA-1273 vaccine injection was reported. The COVID-19 vaccines may play a role in various immune-related dermatologic conditions.


[1] We estimate the accuracy of cloud top altitude (Z) retrievals from the Atmospheric Infrared Sounder (AIRS) and Advanced Microwave Sounding Unit (AMSU) observing suite (ZA) on board the Earth Observing System Aqua platform. We compare ZA with coincident measurements of Z derived from the micropulse lidar and millimeter wave cloud radar at the Atmospheric Radiation Measurement (ARM) program sites of Nauru and Manus islands (ZARM) and the inferred Z from vertically resolved Microwave Limb Sounder (MLS) ice water content (IWC) retrievals. The mean difference in ZA minus ZARM plus or minus one standard deviation ranges from −2.2 to 1.6 km ± 1.0 to 4.2 km for all cases of AIRS effective cloud fraction (fA) > 0.15 at Manus Island using the cloud radar only. The range of mean values results from using different approaches to determine ZARM, day/night differences, and the magnitude of fA; the variation about the mean decreases for increasing values of fA. Analysis of ZARM from the micropulse lidar at Nauru Island for cases restricted to 0.05 ≤ fA ≤ 0.15 indicates a statistically significant improvement in ZA − ZARM over the cloud radar-derived values at Manus Island. In these cases the ZA − ZARM difference is −1.1 to 2.1 km ± 3.0 to 4.5 km. These results imply that the operational ZA is quantitatively useful for constraining cirrus altitude despite the nominal 45 km horizontal resolution. Mean differences of cloud top pressure (PCLD) inferred from coincident AIRS and MLS ice water content (IWC) retrievals depend upon the method of defining AIRS PCLD (as with the ARM comparisons) over the MLS spatial scale, the peak altitude and maximum value of MLS IWC, and fA. AIRS and MLS yield similar vertical frequency distributions when comparisons are limited to fA > 0.1 and IWC > 1.0 mg m−3. Therefore the agreement depends upon the opacity of the cloud, with decreased agreement for optically tenuous clouds. Further, the mean difference and standard deviation of AIRS and MLS PCLD are highly dependent on the MLS tangent altitude. For MLS tangent altitudes greater than 146 hPa, the strength of the limb technique, the disagreement becomes statistically significant. This implies that AIRS and MLS "agree" in a statistical sense at lower tangent altitudes and "disagree" at higher tangent altitudes. These results provide important insights on upper tropospheric cloudiness as observed by nadir-viewing AIRS and limb-viewing MLS.

The 77 K absorption, emission, steady-state excitation photoselection (SSExP), and time-resolved excitation photoselection (TRExP) results are reported for 11 (Ru(L)/sub 3/)(PF/sub 6/)/sub 2/ complexes with 2,2'-diimine ligands (L). The ligands are 2,2'-bipyridine (bpy), 1,10-phenanthroline (phen), 2,2'-bipyrazine (bpz), 2-(2-pyridyl)quinoline (pq), and 2,2'-biquinoline (biq). Complexes of the form (Ru(L)/sub 3/)/sup 2 +/ (L = bpy, phen, bpz, pq, and biq) were examined as well as mixed-ligand complexes of the form (Ru(bpy)/sub n/(L)/sub 3-n/)/sup 2 +/ (n = 1, 2) (L = phen, bpz, and pq). Data are also presented for the monomeric model complex, (Ru(bpy)(py)/sub 4/)/sup 2 +/ (py = pyridine). Data indicate that optical excitation leads to static localization of the optically excited electron. A model is developed that rationalizes the maximum value obtainable in the SSExP data. Solvent effects observed in the TRExP data are explained in terms of relative rates of spin-lattice relaxation associated with different solvents.


Abstract : A two phase research project investigated the effects of job enrichment and goal setting on worker productivity and satisfaction in a well-controlled, simulated job environment. In the first phase, two conditions of goal setting (assigned goals versus no goals) and two conditions of job enrichment (enriched versus unenriched) were established, producing four experimental conditions. In the second phase (after 2 days work) people with unenriched jobs worked under the enrichment conditions and people originally without goals were assigned goals. Results are discussed in terms of the current theoretical approaches for understanding employee motivation on the job.


Background: Propolis, the bee glue, is increasingly used in biocosmetics and for the self‐treatment of various diseases. Objective: Patients reacting to propolis were requested to participate in further testing with the breakdown constituents of the bee glue. Methods: Twenty‐seven patients agreed to be tested with 18 constituents, including four caffeates (the typical allergens of propolis) derived from the sticky exudates of poplar buds. Results: Seven patients did not react to the propolis constituents tested. In the remaining 20 patients, the four caffeates produced strong reactions. Phenylethyl caffeate, which produced positive reactions in 20 patients, was the leading contact allergen. Benzyl caffeate elicited strong responses in 18 patients, and 3‐methyl‐2‐butenyl caffeate produced reactions in 17 patients. Geranyl caffeate produced positive reactions in 11 patients. The flavonoid tectochrysin gave positive results in 2 patients; ferulic acid, coumaric acid, and methyl cinnamate produced weak responses. Conclusions: In middle Europe, the caffeates are the responsible allergens in propolis allergy. Patients from other countries, where poplar trees do not grow, become allergic to other propolis constituents but not to the caffeates.


Some recent accounts have sought to present Mizrahim —Jews whose origins are in Muslim countries of the Middle East and North Africa rather than in eastern and central Europe — as fellow victims of the Zionist project, along with Palestinian Arabs. On this view, Zionism is an essentially Ashkenazi (European Jewish) project. Here, a more complex account of Mizrahi identity in Israel is presented, showing how Jewish immigrants from Muslim countries, despite being regarded as culturally inferior and treated as colonisation fodder by the Zionist leadership, were nevertheless successfully co-opted to the Zionist project. The Mizrahim continue to face socio-economic disadvantages in Israel but these are predominantly a reflection of class barriers and are fundamentally distinct from the national oppression of Arabs.

Grey forecasting is the method that forecasts the system with uncertain factors through grey theory. This paper presents an improved grey model (GM) algorithm for the medium-long term load forecasting, from which, the optimal parameter is decided by association analysis of historical data. Meanwhile, the method possesses far superior forecast precision through using residual revision and filling innovation. In the article, the authors offer the detailed calculating steps of this method which can be proved that such an algorithm may lead to high performance through experiments conducted on a real power system.

Ultra Wide Band Radar is a novel technology used for breast cancer detection. This imaging modality uses ultra wide band waveforms to form a reflectivity map of the breast region in which tumors can potentially been clearly distinguished. In this study, the authors assess the use of a novel Breast UWBR reconstruction approach, microwave holography, on anthropomorphic phantoms. These phantoms mimic both the shape and dielectric properties of human breast. The images formed using microwave holography are consistent with the location of the synthetic breast structures and show signal to clutter level above 3dB.


Due to the unique characteristics such as simple low-temperature preparation method and high efficiency with a record of over 20%, organometal trihalide perovskite (CH 3 NH 3 PbI 3 )-based solid-state hybrid solar cells have attracted an increasing interest since 2012 when it was reported. During the last several years, some of the fundamental photophysical properties of perovskite related to the high photovoltaic performance have been investigated. Optical absorption, charge separation and recombination are very im‐ portant factors influencing the perovskite solar cell performance. In this chapter, our re‐ cent results of optical absorption, charge separation (electron and hole injection) and charge recombination dynamics at each interface in perovskite solar cells, and their rela‐ tionships to photovoltaic properties will be introduced. Our results suggest that charge recombination is a key factor in improving the performance of the perovskite solar cells. tively. The faster decay process could be attributed to nonradiative recombination of electrons and holes through defects or trap states in MAPbI 3 or at the MAPbI 3 /Y 2 O 3 interface. The relative contribution of the faster decay is less than 10%, which suggests that the defect or trap state density in MAPbI 3 or at the interface is very small, which is consistent with a thermally stimulated current measurement. [39, 40] The slower decay process could be attributed to the recombination of free electrons and holes in MAPbI 3 . This result suggests that the lifetime of the photoexcited charge carriers was very long, which was confirmed to be as much as the order of microseconds by the ns-TA measurement results shown in Figure 3. The TA decay was fitted with eq. (2), and two decay processes were found with lifetimes of 3.7±0.1 µs (70%) and 60±1 µs (30%), respectively. Combining the fs-TA and ns-TA results for MAPbI 3 /Y 2 O 3 , the lifetime of the photoexcited charge carriers in MAPbI 3 can be mostly considered to be as long as the order of microseconds. that the great differences in the IPCE and J sc of the two kinds of cell result from the great difference in the charge recombination between the electrons in TiO 2 and holes in spiro -OMeTAD. These results indicate that the key for improving the IPCE and J sc of the perovskite-based solar cells is charge collection efficiency, instead of charge separation efficiency. Thus suppressing the recombination through proper interfacial engineering for perovskite-based solid hybrid solar cells is crucial for achieving a high efficiency. For the Sn/Pb cocktail perovskite solar cells, it is determined that the bandgap is 1.21 eV and light harvesting can be extended to a wider wavelength over 1000 nm. The Urbach energy is calculated to be 34 meV, which is more than twice that of the MAPbI 3 perovskite. Three recombination processes for the photoexcited carriers were found with lifetimes being 4 ps (55%), 650 ps (25%) and one much larger than 3 ns (20%). The larger Urbach energy and the faster recombination suggest that there are defects in the prepared Sn/Pb cocktail perovskite. These results are significantly different from those of the MAPbI 3 perovskite, in which case the photocarrier lifetimes are larger than 100 ns and almost no defects were observed. Moreover, the charge separation and charge recombination dynamics were explored. We find that both the electron injection into TiO 2 and the charge recombination lifetime became shorter, i.e., 190 µs, when P3HT was employed as a HTM. This implies that the charges can be more effectively collected without the HTM. On the basis of the above results, we find that the loss in the charge separation efficiency originates from fast photoexcited carrier recombination with a lifetime of 4 ps, and the loss in charge collection efficiency was due to the charge recombination occurring at the TiO 2 /P3HT interface, thus leading to lower IPCE values. Also, the low V oc and FF were found to result from the large Urbach energy and the recombination occurring at the TiO 2 /P3HT interface. These findings indicate that the photo‐ voltaic performance of Sn/Pb cocktail perovskite solar cells can be further improved by reducing the defects in the material and the recombination occurring at the TiO 2 /HTM interface through proper interfacial engineering.


Purpose: The goal of this presentation is to describe and assess the many types of operations that can be used to treat excessive gingival display and puffy lips.
Methods: Aesthetic dentistry is swiftly becoming as one of dentistry's most innovative and challenging fields. Patients are becoming more conscious of their physical appearance, and the grin has gotten a lot of attention as a result. Lip operations are becoming more popular among the general public. Various lip surgeries and their modifications have been described in this article, as well as their surgical techniques, indications, and post-operative care. Lip repositioning and lip reduction are discussed in this article. Lip repositioning is a less expensive and time-consuming option for excessive gingival show than more expensive and time-consuming procedures. Lip repositioning has psychological benefits, especially when compared to the low risk. Lip reduction surgery, on the other hand, strives to achieve a balanced relationship between the upper and lower lips that is proportional to the rest of the face, as well as typical lip competence and the appearance of lips that are larger or fuller than desired.

We examined ring-opening polymerizations (ROPs) of e-caprolactone in toluene at 25−60 °C catalyzed by scandium perfluoroalkanesulfonates and perfluoroalkanesulfonimides. Using these scandium catalysts, which have strong electron-withdrawing ligands, the ROPs proceeded quickly. Under identical conditions, polymerizations were completed more rapidly for reactions catalyzed by scandium trifluoromethanesulfonimide [Sc(NTf2)3] and scandium nonafluorobutanesulfonimide [Sc(NNf2)3] than for those catalyzed by scandium trifluoromethanesulfonate [Sc(OTf)3]. It was possible to synthesize poly(e-caprolactone)s (Mn = 2.6 × 103−9.8 × 103) with low polydispersities (Mw/Mn = 1.12−1.40). After polymerization, the catalysts were easily recovered by simple filtration or by extraction with H2O and could be reused. Other rare-earth nonafluorobutanesulfonimides [M(NNf2)3; M = Tm, Sm, and Nd] were also tested. Samarium nonafluorobutanesulfonimide [Sm(NNf2)3], as well as Sc(NNf2)3, catalyzed living polymerizations of e-caprolact...


In this paper, we conducted diagonal methods for designing a non-equidistant linear antenna array with a fixed position of the direction of the maximum of the main lobe of the radiation pattern. This method allows you to get a low sidelobe level (SLL). Of interest is the analysis of a scanning non-equidistant antenna array, in which scanning is carried out by selecting the optimal number of elements from the total number of emitters with super-dense packaging. The interest in such a solution is due to the fact that the array under consideration does not assume the use of controlled phase shifters. Accordingly, the cost of such an antenna array can be significantly reduced compared to traditional solutions. Thus, it is of interest to use aperture antennas as elements of a phased array antenna, which makes it possible to use such arrays as radio interferometers. In radar and the use of ground-based radio interferometry systems with a long and ultra-long base, the position of the phase center and the methods of splitting the periodic structure of the directional multiplier are not of practical importance, but the use of arrays with a controlled phase center is of scientific interest when calculating the radiation pattern of aperture antenna arrays with a small base, as well as compact radio interferometers (LOFAR, SKA), as well as space-based remote sensing systems (SPORT). In the research, we will consider ways to control the radiation pattern of aperture emitters, using the example of mirror antennas, and to change the position of the phase center of the elements in the arrays.


Abstract : The study was designed to assess the factors influencing the career motivation of Navy physicians and dentists and to evaluate differential career incentives. A structured multiple-choice mail questionnaire was administered in March 1973. Twenty-six job factors were found to be related to job satisfaction among physicians and dentists. The respondents expressed satisfaction with such factors as; amount of personal responsibility, relationships with colleagues, security of employment and amount of free time. They were dissatisfied with such factors as; remuneration, quality of facilities and equipment, and the amount of participation they had in making decisions affecting their careers. Both physicians and dentists expected job satisfaction to be potentially higher in civilian life than in the Navy. Twenty-five recommendations were made to improve job satisfaction and retention among physicians and dentists in the Navy.

This chapter examines the processes underlying interpersonal interactions in both healthy control individuals (HC) and those with major depressive disorder (MDD). The chapter focuses on four key types of social cognition that give rise to the intricate and dynamic nature of human social functioning, including self-referential processing, other-processing ('theory of mind'), moral emotion, and social decision-making. It reviews studies investigating the neural substrates of social cognition in HC and MDD, most commonly using functional magnetic resonance imaging. Key brain areas identified include prefrontal cortex (PFC; including, most prevalently, the orbitolateral, medial–lateral, and dorsolateral PFC), temporal–parietal regions (in relation to theory of mind), and subgenual anterior cingulate cortex (in relation to both specific moral emotions, such as guilt, and moral content more generally).

The purpose of semantic web research is to transform the Web from a linked document repository into a distributed knowledge base and application platform, thus allowing the vast range of available information and services to be more efficiently exploited. As a first step in this transformation, languages such as OWL have been developed. Although fully realizing the Semantic Web still seems some way off, OWL has already been very successful and has rapidly become a defacto standard for ontology development in fields as diverse as geography, geology, astronomy, agriculture, defence and the life sciences. The aim of this paper is to classify key concepts of Semantic Web as well as introducing a new practical approach which uses these concepts to outperform Word Wide Web. Keywords—Semantic Web, Ontology, OWL, Microformat, Word Wide Web.


ABSTRACT To date, aging is one of the most important issues in our society because of its significant socioeconomic impacts. Corresponding concerns about the transportation needs of the elderly have led to a focus on the mobility and quality of life of the elderly and motivated various studies of senior mobility. As the fastest aging country in the world, Korea will need to provide insightful information for an aging society. The purpose of this study is to investigate the difference in travel behavior between the elderly and the nonelderly groups by focusing on travel time budget (TTB), using the 2006 household travel diary survey data from the Seoul metropolitan area. We develop partial least square (PLS) structural equation models to identify major variables that affect the TTB of each of the two groups and then compare the differences between the models. Model results indicate that the significant explanatory variables differ between the two age groups, and the degree to which the variables affect the TTB differs by personal and household characteristics.

The results from numerical simulations analysis indicated that yarn obtained from the Pineapple leaf fiber (PALF) had great potential to be used in apparels.


Metabolic compromise, excitotoxicity,and oxidative stress are three main mechanisms of neuronal cell death,they may act separately or cooperatively to cause neurodegeneration. These three mechanisms are believed to play a role in the neurodegeneration that occurs in both Parkinson's and Huntington's diseases. Strategies to rescue or protect injured neurons usually involve promoting neuronal growth and function or interfering with neurotoxic processes. This paper attempts to review the strategies to protect the neurodegeneration that occurs in both Parkinson's and Huntington's diseases.


In view of the advent of large-scale neutrino detectors such as IceCube, the future Hyper-Kamiokande and the ones proposed for the Laguna project in Europe, we re-examine the determination of the directional position of a Galactic supernova by means of its neutrinos using the triangulation method. We study the dependence of the pointing accuracy on the arrival time resolution of supernova neutrinos at different detectors. For a failed supernova, we expect better results due to the abrupt termination of the neutrino emission which allows one to measure the arrival time with higher precision. We found that for the time resolution of $\pm$ 2 (4) ms, the supernova can be located with a precision of $\sim$ 5 (10)$^\circ$ on the declination and of $\sim$ 8 (15)$^\circ$ on the right ascension angle, if we combine the observations from detectors at four different sites.


193 Dear Editor, Folliculitis decalvans (FD) is a rare scalp disorder characterized by cicatricial alopecia, hair‐tufting, and pustule formation.[1] Staphylococcus aureus appears to be crucial in FD pathogenesis and may result from an abnormal host response to the bacterium.[1] Targeting S. aureus with prolonged/multiple antibiotics is the mainstay of therapy.[1] The World Health Organization's Global Antimicrobial Surveillance System recently highlighted the increasing antimicrobial resistance, with S. aureus being one of the most commonly reported resistant bacteria.[2]


Formation of tolerance through a multicultural environment in higher educational institutions is of particular relevance because the number of international students increases, migrants from non-CIS countries flow into the territory of the Russian Federation, and many nations and confessions live both in the Republic of Tatarstan and the Russian Federation. The aim of our study is to identify and systematize the essential characteristics of the algorithm in the formation of students' tolerance in a multicultural environment, its approbation and implementation in the process of foreign language teaching at the university. An analysis of the literature, teaching experience, and empirical studies enabled to identify the criteria and levels of students' tolerance formation as well as to create special pedagogical conditions to provide students' stability under stressful, difficult situations in the learning activities. As a result of research, we defined the following pedagogical conditions: the development of students' emotional stability in teaching and learning activities through the parallel algorithm as a precise prescription of a phased fulfillment of actions, intensive introduction of interactive forms of teaching, and the use of extracurricular forms of work. Actualization of these pedagogical conditions for tolerance formation in foreign language environment contributes to encouraging fluency in foreign language by international students and further development of foreign language skills; development of skills for self-analysis and self-criticism; promoting social citizenship, proactivity, adaptability and optimism. © 2016 Published by Future Academy www.FutureAcademy.org.uk


In this work, we analyzed and compared speech representations extracted from different frozen self-supervised learning (SSL) speech pre-trained models on their ability to capture articulatory features (AF) information and their subsequent prediction of phone recognition performance for within and across language scenarios. Specifically, we compared CPC, wav2vec 2.0, and HuBert. First, frame-level AF probing tasks were implemented. Subsequently, phone-level end-to-end ASR sys-tems for phoneme recognition tasks were implemented, and the performance on the frame-level AF probing task and the phone accuracy were correlated. Compared to the conventional speech representation MFCC, all SSL pre-trained speech representations captured more AF information, and achieved better phoneme recognition performance within and across languages, with HuBert performing best. The frame-level AF probing task is a good predictor of phoneme recognition performance, showing the importance of capturing AF information in the speech representations. Compared with MFCC, in the within-language scenario, the performance of these SSL speech pre-trained models on AF probing tasks achieved a maximum relative increase of 34.4%, and it resulted in the lowest PER of 10.2%. In the cross-language scenario, the maximum relative increase of 26.7% also resulted in the lowest PER of 23.0%.


Homer – the origins of European reflection on mercy The Author goes back to the beginnings of European reflection on human mercy – to the text by Homer. He analyses The Iliad (8th century BC) and on that basis determines the semantic features of mercy. And then he points out the similarities and differences between the conceptualizations of mercy in Dives in misericordia and in The Iliad. Homeric hero is a man of noble (esthlós, áristos), not only because he has the honor, knows his value (timé), but his life is guided by sensitivity to the dignity of others. He is a righteous man (díkaios), it means that he is able to acknowledge his guilt or error. On the other hand he can be guided by mercy: in the language of Homer he is able to 'show the gracious soul' (híleos). When we compare these concepts with papal it turns out that they are identical, but their hierarchy and the quality is different. In John Paul II: love (of God), justice, mercy, dignity but in The Iliad the direction is reversed: dignity, justice, mercy, which opens the way to human love.


Resting heart rate is an independent risk factor for cardiovascular disease and is mainly controlled by β‐blockers (BBs). BBs are part of the optimal medical treatment for coronary artery disease (CAD), and their benefit correlates with resting heart rate (RHR) reduction.


This study considers the development of optimization models for grade transition of polyethylene solution polymerization processes. A detailed mathematical model is developed to capture the dynamics of the solution polymerization process. This includes time delay models for vapor and liquid recycle streams as well as a reduced, yet accurate, vapor-liquid equilibrium (VLE) model derived from rigorous VLE calculations. Simultaneous dynamic optimization approach is applied to solve the optimization problem to reduce off-spec production time and transition time. Two optimization formulations, single stage and multistage, are developed to deal with single-value target and specification bands of product properties, respectively. The results show significant reductions in grade transition time and off-spec production time. In addition, the multistage formulation designed for problems with specification bands outperforms its single stage counterpart. It minimizes transition time and off-spec production directly, and leads to higher performance control profiles. © 2015 American Institute of Chemical Engineers AIChE J, 62: 1126–1142, 2016


There is a close relation between the structure and function of lake wetland ecosystems and its water level change. In recent years,due to intensive human activities and climate change,Poyang Lake has been subjected to emerging problems,such as earlier onset and extended duration of low water level condition,wetland degradation and sharp reduction of biodiversity and so on. The purpose of this paper is to explore the suitable water level that lake control project regulates. The CoupModel was used to simulate the respiration for maintenance and growth of Carex cinerascens from September to November during 1990—2009,and the relationship between the respiration amount of the Carex cinerascens and the dairy water level of the Xingzi hydrological station in Poyang Lake was established,using the artificial neural network,the response of the Poyang Lake wetland on the water level change was analyzed. The results indicate that the accumulated respiration amount of Carex presents a downward trend,which is 3. 5% less after the Three Gorges Reservoir water storage than that before the Three Gorges Reservoir water storage. This study proposed three kinds of water level regulation schemes( high,medium and low water level),and the established neural network model was used to predict the variation of the accumulated respiration amount of Carex during the growth period under different regulation schemes. The results show that medium water level scheme improves the respiration amount of Carex after the Three Gorges Reservoir water storage obviously,which has obvious effect on the protection and restoration of the wetland ecosystem,while both other regulation schemes show no obvious effect. The results can provide a scientific basis for development of suitable regulation schemes of ecological water level in Poyang Lake wetland.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by loss of motor neurons and appearance of skein‐like inclusions. The inclusions are composed of trans‐activation response (TAR) DNA‐binding protein 43 (TDP‐43), a member of the heterogeneous nuclear ribonucleoprotein (hnRNP) family. hnRNPA1 and hnRNPA2/B1 are hnRNPs that interact with the C‐terminus of TDP‐43. Using immunohistochemistry, we investigated the association between TDP‐43 and hnRNPA1 in ALS spinal motor neurons. We examined spinal cords of seven ALS cases and six muscular dystrophy cases (used as controls) for the presence of TDP‐43 and hnRNPA1 protein. In the control cases, hnRNPA1 immunoreactivity in motor neurons was intense in the nucleus and weak in the cytoplasm where it showed a fine granular appearance. In the ALS cases, hnRNPA1 immunoreactivity in motor neurons was reduced in the nuclei of neurons with skein‐like inclusions but was not detected in the skein‐like inclusions. The marked loss of hnRNPA1 in motor neurons with concomitant cytoplasmic aggregation of TDP‐43 may represent a severe disturbance of mRNA processing, suggesting a key role in progressive neuronal death in ALS.


The impact of physicochemical properties of imidazolium based different ionic liquids such as BDMIMBF4, BMIMBF, and EMIMBF4 on the ion conduction and relaxation mechanisms in ionogels is investigated using broadband dielectric spectroscopy. The complex conductivity isotherms of these ionogels are analyzed using a universal power law coupled with a modified Poisson-Nernst-Planck model for the contribution of electrode polarization dominated in the low frequency region. The effect of electrode polarization is analyzed by using the Macdonald-Coelho model to determine free-ion diffusivity and number density in these ionogels. The relaxation process of ions is also systematically studied using electric modulus spectroscopy over wide frequency and temperature ranges. The temperature dependence of the ionic conductivity, free-ion diffusivity, and relaxation times follows the Vogel-Tammann-Fulcher relationship, indicating existence of coupling between the ion transport and segmental dynamics in these ionogels. The EMIMBF4 ionic liquid doped ionogel shows the highest ionic conductivity, lowest relaxation time, highest free-ion diffusivity and highest number density due to the smallest size of cations, highest static dielectric constant, and lowest viscosity of the EMIMBF4 ionic liquid. It is observed that the stretched exponents for different ionogels obtained from Havriliak-Negami and Kohlrausch-Williams-Watts fits of electric modulus are lower than unity, indicating highly nonexponential relaxation in the investigated ionogels.


Binding of platelet glycoprotein Ibα (GPIbα) to von Willebrand factor (vWF) is closely related to the process of physiological hemostasis and pathological thrombosis. Monoclonal antithrombotic antibody SZ2 can inhibit ristocetin induced platelet agglutination and thrombin-induced platelet aggregation via binding to the anionic region of GPIbα. To investigate the interaction between SZ2 and GPIbα at the residue level, here we perform a computational modeling via homology modeling, molecular docking and intermolecular interactions analysis. Proper conformations of SZ2 and SZ2/GPIbα complex are presented; the key residues in SZ2 and GPIbα are also identified, which are consistent with known experimental evidence. Our study may provide novel insights into SZ2 modification and antibody research, especially in lacking of both crystal structures and mutagenesis data.


As the weakest part of building facades, glass panels can easily break in fires and change the compartment fire dynamics by creating new openings for air to enter. A series of full scale tests were conducted to investigate the thermal breakage and fallout of four-point fixed glass facades, in which glass panes of 1200 × 1200 × 6 (mm 3 ) were placed at 35, 45, 50 and 70 (cm) away from n-heptane pool fires on a 500 × 500 (mm 2 ) square pan. Both float and toughened glasses were investigated. The glass surface temperature, gas temperature at the centre of the exposed side and heat release rate were measured and analyzed. The cracking patterns and glass fallout processes were recorded by digital camera. It is found that all the cracks initiated from the fixed point and their intersections formed islands to cause glass pieces fallout when the exposed side reached around 200-300 °C for the float glasses tested. The fallout fractions suggest that once the first crack is initiated, the point-supported glass panes are much more easily to fallout than edge covered glasses. The toughened glass panes were found to be softened by the fire and bent, but they did not crack even when the fire directly impinged on them.


In this paper we study what type of exogenous (related to the external structure) and endogenous (related to the firm) aspects affect industry´competitiveness. The framework is used to asses competitiveness of organizations in the Spanish furniture industry. In doing so, we deep in the theoretical concepts related: in one hand, the industrial sinergical concentration and, in the other hand, literature concerned to resources and capabilities. In this way, we apply a conceptual framework developed by the authors in order to identify the critical aspects that can influence competitiveness and, then, describe the results. The applicability of the model is analyzed in the Spanish furniture industry, specifically in the Valencian Community, where is mainly concentred. From the results obtained we are able to conclude that the method is effective in identifying both exogenous and endogenous aspects.
