Manufacturing is the process of producing effective products through the use of machinery, labor, tools and well-formulated theory. During the manufacturing process, industries experience various kinds of provocations, including unexpected failures of equipment and machines, downtime failures and products delivered in an imperfect way. In industry 4.0, smart manufacturing is used to rectify these challenges and faults during the manufacturing process and it includes all intermediate processes required for the integration of smart manufacturing technologies into industry. In detail, digital technology has been applied to the face of the industrial and manufacturing world, which is called smart manufacturing. This paper presents the technologies involved in the manufacturing process in a smart way in Industry 4.0. The merging of various emerging technologies such as the Internet of Things (IoT), Cyber Security, Big Data, Cloud Computing, Automation, Augmented Reality and virtual reality have been enabled in the industry 4.0. These technologies are used to upgrade how manufacturers improve and enhance operational efficiency, develop and launch new products with quality, design customized products and AI with digital transformations are used to make the manufacturing process smarter in the industry.


This paper presents a study to improve and enrich understanding of how the disclosure or non-disclosure of a lesbian, gay male, or bisexual teacher's sexual orientation at work influences his or her perceptions of job satisfaction and job stress. Consideration was given to the general level of job satisfaction and job stress among lesbian, gay male, and bisexual teachers as contrasted to previous studies using the same'instrumentation with assumed heterosexual populations. Differences among the three affectional identity groups were examined in the areas of job satisfaction, job stress, and identity disclosure. Membership in a gay teacher organization was appraised as a factor. Supplementary analysis was undertaken to assess the effects of tenure, age, level of school, type of community, and AIDS deaths on job satisfaction, job stress, identity, and demographic variables. This study was concerned only with the effects of openness on job satisfaction and job stress. The significance of being either open or closeted about one's sexual orientation at work influenced the perceived levels of job stress and job satisfaction of lesbian, gay male, and bisexual teachers. Eight appendices contain: (1) definitions of factors in the Teacher Job Satisfaction Questionnaire (TJSQ); (2) teacher stress items from LPCQ; (3) definition of factors/Level of Professional Challenge Questionnaire (LPCQ); (4) the Identity Disclosure Questionnaire (IDQ); (5) definitions of IDQ factors; (6) demographic data section; (7) cross tabulation of type of community by affectional identity with number, percent of row, and percent of column; and (8) summary of significant results by variables across instrument factors.

Strategic planning is clearly a line function at PepsiCo. In stronger terms, strategy is the essence of our business and the responsibility of each of our division presidents. This is the one responsibility we do not allow them to delegate. They can have strategic planning departments—as long as they realize that they're the strategic planners.


While the data analysis of $\gamma$-ray telescopes has now become more robust, some signals may be misinterpretations of a time-variable foreground emission from the Solar System, induced by low-energy cosmic-ray interactions with asteroids. Our goal is to provide emission templates for this time-variable diffuse $\gamma$-ray foreground by considering the populations of Main Belt Asteroids, Jovian and Neptunian Trojans, Kuiper Belt Objects, and the Oort Cloud. We model the spatial distribution of all known asteroids by performing 3D-fits to determine their density profiles and calculate their appearances by line-of-sight integrations. Because Earth and the asteroids are moving with respect to each other, we obtain diffuse emission templates varying on timescales of days to decades. We find that the temporal variability can lead to flux enhancements which may mimic emission features unless properly taken into account. This variation is further enhanced by the Solar cycle as the cosmic-ray spectrum is attenuated by the Solar modulation potential, leading to a relative flux increase of the outer asteroids. The cumulative effect of the time-dependent emission is illustrated for the case of the 511 keV OSSE fountain, and for emission features near the Galactic Centre, both being possible misinterpretations of the Solar System albedo. We recommend that $\gamma$-ray data analyses should always take into account the possibility of a time-variable foreground. Due to the ecliptic overlap with the Galactic plane, the Galactic emission is expected to be weaker by 0.1-20%, depending on time (relative planetary motion), energy, and Solar cycle, which has immense consequences for the interpretation of dark matter annihilation cross sections, cosmic-ray spectra and amplitudes, as well as nucleosynthesis yields and related parameters.


ABSRACT The aim of this study was to determine the occurrence and distribution of organic pollutants in the Lower Tennessee River Basin's soil/sediment matrix and develop the hazard quotient for the Flint Creek and Flint River watersheds. Pharmaceutical and industrial pollutants represent the newest pollutants discovered at these watersheds. Gas Chromatography — Electron Capture Detection/Photo-ionization was used to detect all compounds. A modest to substantial amount of the compounds were detected in samples collected from both watersheds during the winter season of 2011. Results showed that there was an increasing trend of polycyclic aromatic hydrocarbons (PAH) in Flint River. Pharmaceuticals, gasoline products, SVOCs, and other organic chemicals, were all present in Flint River in large doses as well. Distribution of the industrial pollutants in the Flint Creek showed that it contained more pharmaceuticals and gasoline components than the Flint River. The results of the Ecological Risk Assessment or Hazard Quotient (HQ) for the pollutants for all sites indicated a potential for adverse ecological effects, and that a more thorough study is necessary. Testing in the Flint Creek and Flint River watersheds mirrors national studies that show it's a real problem almost everywhere, with unknown consequences. The findings from this study will fill an existing gap in knowledge, and allow environmental agencies to improve management decisions and develop meaningful guidelines for protecting Alabama's water resources.


Inequalities in health are noticeable among older people in many developing countries, driven by poor social protection systems and low socio-economic status (SES). The present study attempts to examine the effects of SES on health of older adults, and related gender differences, in rural Bangladesh and India using standardized data collection instruments. The study uses the INDEPTH-WHO SAGE Matlab, Bangladesh and Pune District, India datasets. Quintiles of wealth and educational attainment are used as the indicators of socio-economic status, while self-rated health, quality of life, health state, and disability level are used as health indicators. In multiple regression models, both SES indicators are significantly associated with each health status indicator in older adults in Bangladesh, whereas, in India, they are found to be not consistently associated with the four health indicators. Highest level of education is a better predictor of the four health indicators than wealth among older adults in both countries. The findings have profound implications with regard to designing health intervention programmes for older adult populations in both countries.


An array of 27 ionization chambers has been used to observe the density distribution of particles near the axis of small air showers (N = 10/sup 5/). The results for the first ten events (near hits) can be described by NishimuraKamata distributions with age parameter, s, greater than one. A cloud chamber at the center of the array was used to measure the intensity of the mu- meson and of the nuclear-interacting components. The statistics of the first ten events permit only rough determinations of these intensitie s. (auth)


The utility model relates to a silicon material sorting device in the photovoltaic or semiconductor field, in particular to a vortex device for separating normal silicon material from metal or heavily doped silicon material. The silicon material sorting device is provided with a vortex detector and a separating mechanism; and when the silicon material is mixed with metal or heavily doped silicon material, vortex generates in the silicon material, the vortex detector sends out alarm sound and then the metal or the heavily doped silicon material is separated from the normal silicon material. By the silicon material sorting device, the metal or the heavily doped silicon material mixed in the silicon material can be removed completely and the obtained silicon material after sorting can be reused as the material of polysilicon ingots.


To best understand the use of dried blood spots (DBS) in clinical chemistry, we must first differentiate laboratory screening from diagnostics. Newborn screening (NBS) utilizes DBS to detect and quantify biomarkers indicative of more than 50 congenital diseases primarily of metabolic origin [1]. Many different methods are used, including modern analytical technologies such as tandem mass spectrometry (MS/MS) [2, 3] and molecular analyses [4, 5]. Each method is designed specifically to analyze DBS specimens with laboratory protocols and systems that begin with a paper hole puncher rather than a pipette. Unfortunately, NBS is often differentiated from clinical chemistry because it is "screening" tool rather than a "diagnostic" application. This is a common misconception because no method is diagnostic, but rather leads to a physician diagnosis that is based, in part, on laboratory results. Like any clinical test, NBS results take into consideration additional data such as age of newborn, birth weight, gestational age, and nutritional status [6–8]. Additionally, NBS is regulated by a comprehensive quality assurance/quality control (QA/QC) network that is shared worldwide [9]. There are a small number of traditional clinical laboratories that use DBS in a diagnostic setting, primarily in specialized metabolic applications, further supporting that DBS utilization is not restricted to "screening" laboratories, nor does it involve relaxed laboratory standards. The question is: why are DBS not used to a greater extent in traditional clinical laboratories? It is likely due to the analytical challenges and common misperceptions of the DBS. Specifically, the challenges of DBS implementation such as cross-validation of a DBS assay from a liquid sample analysis, logistical systems limitations for handling DBS versus liquid samples, and clinical laboratory bias towards single metabolite analysis versus metabolic profiles.


This paper deals with a fast charging icon-shaped slotted antenna (FCISA) which is designed to operate at 2.536 GHz. This antenna covers the frequency band from 2.389 GHz to 2.6968 GHz which is applicable for 2.45 GHz Bluetooth (2.407 GHz to 2.484 GHz), 2.4 GHz Wi-Fi (2.407 GHz to 2.484 GHz), WiMAX rel 1 (2.3 GHz to 2.40 GHz) and WiMAX rel 1.5 (2.5 GHz to 2.69 GHz). The overall dimension of the antenna is $40\times 38\times 0.79mm^{3}$ which etched on Rogers RT 5880 ($\varepsilon_{r}$=2.2, $\delta$= 0.0009). The maximum gain and directivity of the antenna are 3.16 dB and 3.51 dBi respectively. The reflection coefficient of this antenna is -40.699dB with approximately unity VSWR (1.0186) which operates at a resonant frequency of 2.536 GHz. The radiation efficiency of the fast charging icon-shaped slotted antenna is always above 90%. Thus the antenna is quite appropriate for Bluetooth, Wi-Fi and WiMAX applications.


We present a versatile system for training social skills with interactive virtual agents reacting to the user's automatically assessed performance.


Empirical work related to African spirituality in the social sciences, particularly within the social work context, is sparse. It is crucial that practitioners have a deeper understanding of the beliefs and practices that can support therapeutic goals in practice. Using qualitative research methodology, 20 child and youth care students at a selected university in South Africa, who are proponents of African spirituality, were interviewed with regards to their  beliefs and practices. The major objective was to gain a richer insight into African spirituality and those African healing methodologies considered most relevant to child and youth care practice.  Prayer to the ancestral spirits, sacrificial rituals and music were considered to be some of the most important practices identified that could guide both child and youth care practice and social work.


Evidence for pulmonary involvement was sought in 98 unselected patients with progressive systemic sclerosis. Objective manifestations, viz. persistent fine rales, roentgenographic fine reticular markings, or certain abnormalities of pulmonary functions, were found in 61 of the patients. The most sensitive indicator of respiratory dysfunctions, were was a reduction in diffusing capacity to less than 60% of the predicted normal (55 out of 98). The vital capacity was usually reduced and the single breath oxygen value was often elevated when the disease process was more severe; the functional residual capacity and tests of airway conductance remained unaffected. The severity of the pulmonary physiological abnormalities was related to the presence both of respiratory symptoms and signs and of radiographic findings. Pulmonary disease tended to be associated with cutaneous involvement of the head and neck, with esophageal abnormality, and with Raynaud's phenomenon, but not with the duration of the disease.


Surface-active agents as chemical admixtures are widely used in concrete industry to improve the properties of fresh concrete. By the introduction of admixtures, the use of high strength concrete with low water content became popular, and the durability of concrete structures was largely improved. The most frequently used admixtures are (1) water-reducing and setretarding admixtures to reduce the water requirement of concrete or retard the set, or both [these include ligninsulfonic acid, hydroxylcarboxylic acids, carbohydrates, polyols, and the salts], (2)air-entraining admixtures to introduce a system of small air bubbles into the fresh concrete dung mixing [these are anionic surface-active agnets]. A new group of water-reducing admixtures, termed superplasticizers, has been introduced in the last few years [these are naphthalenesulfonic acid, specific ligninsulfonic acid, and polycarboxylic acid]. They are about twice as effective as the conventional admixtures.


As with the maturation and diversification of social services, social data outsourcing has become pervasive. In this context, online social networks outsource their real-time social data to a social data provider, who responses to query requests issued from data consumers. However, dishonest or malicious social data providers might tamper with collected social data by adding fake data and deleting/modifying raw data, and further return inauthentic query results to data consumers. In this article, we make the first attempt to study the problem of authenticity verification for dynamic social data. To this end, we first propose a novel authenticity verification framework, and then, propose a self-balancing hash tree scheme to tackle challenges brought on by the vast scale and dynamics of social data. To maximize the search efficiency for the self-balancing hash tree, we introduce a balance factor to define an unbalanced node as its balance factor is not chosen from a predetermined set. Furthermore, we propose three algorithms to balance unbalanced nodes in the self-balancing hash tree. Rigorous theoretical analyses prove that our framework can determinately detect any fake query results returned by data consumers. Experimental results built on a real Twitter dataset show that our scheme is efficient and effective.

The interaction of PC-based unilamellar liposomes incorporating the complementary 5,5 di-n-dodecylbarbituric acid (DBA) or 9-hexadecyladenine (HA) in various molar ratios has been investigated using imaging, spectroscopicand calorimetric techniques. Liposomal interaction was established by turbidimetry, AFM, and optical microscopy and also by isothermal titration calorimetry. For temperatures below the main lipid phase transition, the results provide evidence for hydrogen-bonding between the adenine and the barbituric acid moieties at the lipid-water-lipid interfaces with a stoichiometry ratio of 1:1. The interaction does not lead to disruption of the liposomes but instead it affords larger aggregates. The role of cholesterol in the DBA-HA binding, at high concentrations in the PC:DBA and PC:HA bilayers has also been investigated. Evidence is found that the presence of cholesterol (at molar concentration 2:1 relative to PC) alters the DBA/HA binding mechanism. For all the systems studied, no liposomal binding could be calorimetrically detected above the main lipid phase transition temperature.


Active Queue Management is a way to control Congestion. The existing RED (Random Early Detection) Active Queue Management algorithm and its variants are found vulnerable to emerging LDoS attacks. The RRED algorithm was proposed to improve TCP throughput under LDoS attacks by detecting and filtering out attack packet. We conduct a set of simulation to compare and evaluate the performance of RED and RRED under normal TCP traffic without LDoS attacks and With LDoS attacks. The results show that, RRED algorithm nearly fully preserves the TCP throughput in the presence of LDoS attacks. Simulation is done by using Network Simulator (NS2)


We analyze holomorphic Jacobi forms of weight one with level. One such form plays an important role in umbral moonshine, leading to simplifications of the statements of the umbral moonshine conjectures. We prove that nonzero holomorphic Jacobi forms of weight one do not exist for many combinations of index and level, and use this to establish a characterization of the McKay–Thompson series of umbral moonshine in terms of Rademacher sums.

Objective To explore the association of vitamin D receptor(VDR) gene polymorphisms with asthma and wheezy bronchitis in children.Methods Both polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP) and gene sequence analysis methods were used to analyze VDR gene differences in 30 asthma,40 wheezy bronchitis and 40 healthy control children.Results A significant difference was found in the frequency distribution of VDR gene type among three groups(χ2=11.726,P=0.020).The assay of paired comparison confirmed the differences of VDR gene frequency distribution between the children of asthma and of bronchitis(χ2=10.546,P=0.005),and also of health controls(χ2=9.317,P=0.009).However,the difference was not significant between the children of wheezy bronchitis and of healthy controls(χ2=0.06,P=0.97).The VDR allele frequencies of ApaI polymorphism were also different among three groups(χ2=8.561,P=0.014).The assay of paired comparison suggested the differences between the children of asthma group and of control group(χ2=6.850,P=0.009) as well as of wheezy bronchitis group(χ2=7.622,P=0.005),but not between the children of wheezy bronchitis group and of healthy control group(χ2=0.028,P=0.876).Conclusion The results suggested the association of ApaI polymorphism of the VDR gene with children asthma.


The Spallation Neutron Source (SNS) [1] has been recently commissioned. Strategies for the initial beam commissioning of the linac and storage ring will be discussed. The superconducting linac (SCL) commissioning posed unique challenges, in particular accommodating an unanticipated wide range of cavity performance. Methods for setting cavity phases and determination of amplitudes will be discussed. The ring commissioning involved the usual establishment of a circulating beam, and then measurement and correction the tune and beta functions, all with a low intensity beam. Then the gradual increase of beam intensity and phase space painting were investigated. The methods to accomplish these tasks will be discussed. Key factors in the successful commissioning were flexibility in accommodating beam conditions that are different from the design, model based applications, good communication between the different groups, and prebeam testing.

The highlights of these research and technology efforts are described.


Introduction
Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CCA) has wide histologic diversity. This study investigated the prognostic impacts of cHCC-CCA histology according to the 2019 World Health Organization (WHO) classification.

Methods
This retrospective observational study included 153 patients who underwent surgical resection for cHCC-CCA at Asan Medical Center between August 2012 and July 2019.

Results
During the study period, 153 patients, 112 (73.2%) men and 41 (26.8%) women with a mean age of 56.4 ± 10.8 years, underwent R0 resection for cHCC-CCA. Mean tumor diameter was 4.2 ± 2.6 cm, and 147 (96.1%) patients had solitary tumors. According to 2019 World Health Organization (WHO) classification, 111 (72.5%) patients had cHCC-CCA alone, and 29 of them (26.1%) showed stem cell features. cHCC-CCA-intermediate cell carcinoma and cHCC-CCA-cholangiolocellular carcinoma were identified in 27 (17.6%) and 15 (9.8%), respectively. The 1-, 3-, and 5-year tumor recurrence and patient survival rates were 31.8% and 92.1%, 49.8% and 70.9%, and 59.0% and 61.7%, respectively. Univariate analyses revealed that significant prognostic factors were tumor size > 5 cm, microscopic and macroscopic vascular invasion, lymph node metastasis, 8th American Joint Committee on Cancer (AJCC) tumor stage, and status of stem cell feature. Multivariate analysis revealed 8th AJCC tumor stage and status of stem cell features as independent prognostic factors. The 2019 WHO classification was not associated with post-resection prognosis.

Conclusions
The 2019 WHO classification was not associated with post-resection prognosis, thus was considered as a simple histologic classification. We suggest that stem cell features should be included as an essential component of the pathology report for cHCC-CCA.


A difference mean-velocity turbulence model to calculate quasistationary fully developed turbulent motion is presented. It takes account of the various eddy sizes in turbulent flows. As a consequence, some gaps between semiempirical closure models and sophisticated theories, describing eddy energy cascades, are reduced. In a first-order expansion, the model is identical to Prandtl's mixing-length theory, which is still contained in modern numerical computation schemes, e.g., k-\ensuremath{\epsilon} models.


Allowed weak interaction rates for sd-shell nuclei in stellar environment are calculated using a generalized form of proton-neutron quasiparticle RPA model with separable Gamow-Teller forces. Twelve different weak rates are calculated for each nucleus as a function of temperature and density. The stellar weak rates are calculated over a wide range of densities (10≤ ρYe (gcm −3) ≤ 10 11) and temperatures (10 7 ≤ T(K) ≤ 30 × 10 9). This project consists of calculation of weak rates for a total of 709 nuclei with masses ranging from A = 18 to 100. This paper contains calculated weak rates for sd-shell nuclei. The calculated capture and decay rates take into consideration the latest experimental energy levels and f t value compilations. The results are also compared with earlier works. Particle emission processes from excited states, previously ignored, are taken into account, and are found to significantly affect some β decay rates. There are many interesting problems in astrophysics which require e ±-capture and β ±-decay rates as input parameters. These rates are used in numerical simulations for nuclear astrophysi-cal problems. In the course of development of a star, the weak interaction has several crucial effects. They initiate the gravitational collapse of the core of a massive star triggering a supernova explosion, play a key role in neutronisation of the core material, and, affect the formation of heavy elements above iron via the r-process at the final stage of the supernova explosion. The weak interaction also largely determines the mass of the core, and thus the strength and fate of the shock wave formed by the supernova explosion. Precise knowledge of the β decay of neutron-rich nuclei is crucial to an understanding of the r-process. Both the element distribution on the r-path, and the resulting final distribution of stable elements are highly sensitive to the β decay properties of the neutron-rich nuclei involved in the process. This was first pointed out by Klapdor [1,2,3] (see also [4]).There are about 6000 nuclei between the β stability line and the neutron drip line. Most of these nuclei cannot be produced in terrestrial laboratories and one has to rely on theoretical ex-trapolations in respect of beta decay properties. Calculations of beta decay rates for all nuclei far from stability by microscopic nuclear theory were first performed by Klapdor et al.[5], and then complemented and refined by Staudt et al. [6,7] and Hirsch et …


Based on the analysis of Snort's rule and the princIPle of instruction detection system for snort,combined with the char-acteristic and security mechanisms of IPv6,this paper puts forward a dynamic rule-matching mechanism for IPv6. In order to adjust the sequence of rule-matching dynamically,it adds a chain of the option index. It carries out the quickness and efficiency of the in-struction detection system for IPv6. The experiment shows that the system not only detects kinds of attacking for IPv6,but improves detection speed about 12.53%.


This paper introduces the features of pro under the binding theory and stresses how significant it is to research into Chinese pro. Having reviewed the heated debates on Chinese finiteness and nonfiniteness among many linguists,the author proposes the criterion for judging Chinese finite and non-finite clauses,thus throwing light on the grounds on which Chinese and English pro exists. Furthermore,the author draws a comparison of Chinese pro with English pro in terms of the licensing mechanism and references.


Experimental results have been obtained for flow through a contracting, 90-deg, rectangular Stanitz elbow with thickened endwali boundary layers to generate passage vortices and strong secondary flow. This includes Pitot-static and LDV measurements for inflow boundary conditions. The data were used as the basis for three- dimensional viscous code validation based on a two-equation q-u turbulence model using both integration to the wall and a wall-function treatment. Wall functions were found to be reliable for the complex three-dimen- sional flow considered. Eddy viscosity well away from walls appears to be over predicted. HE Stanitz elbow was originally introduced to test certain aspects of secondary flow development in a turbine vane, namely, that associated with passage vortex formation and intensification in a contracting turn.1 The geometry was de- signed to avoid adverse pressure gradients and hence the detri- mental influence of separation. Experiments were conducted with the configuration shown in Fig. 1, including the option of spoilers upstream to simulate thickened endwali boundary layers which are characteristic of turbomachiner y.2 Subse- quent studies on this rectangular duct at our organization will be the focus of this paper. The experiment has been repeated to broaden the database, including wall pressure measurements on the endwali and operation at high subsonic Mach number. Definition of inflow boundary conditions is also emphasized due to significance of these in code validation. Computational studies assess model- ing capability for a complex three-dimensional turbulent flow- field. This is based on Coakley's two-equation g-u model,3 using both integration to the wall and a wall-function treat- ment. The latter performs well even in the presence of strong secondary flow, and could lead to significant reduction in gridding requirements for three-dimensional viscous cascade flow simulation. Representative results from this combined experimental/theoretical study are summarized below. Code Validation Experiment The experiments were conducted in the Aerodynamic Test Facility4 at Avco Research Laboratory (ARL). This facility can be operated in two modes: continuous operation at mass flow of up to 2.3 kg/s at 9.5 atm, or blowdown operation with mass flow up to 18 kg/s at 32 atm for 20 s test duration. The facility is fully computer controlled, including automated traversing equipment for Pitot-static and .Pilot probes, and is capable of aggregate data-collection rates of 1 MHz into a MASSCOMP computer. This allows extensive data collection in a matter of seconds and display of results to assess data quality in minutes. Reliable and repeatable blowdown perfor- mance was established by conducting the Stanitz elbow experiment, an underlying reason for choosing a configura- tion that had been studied previously.


Eucaryotic mRNAsaregenerally localized inthecell body,wheremostprotein synthesis occurs.We have foundthatmRNAsencoding theglial intermediate filament protein arespatially distributed intheglial cell cytoplasm close tothelocation oftheglial filaments.

Quantitative studies about vegetation in Mexico have focused on tropical and cloud mountain forests, compared to which those of temperate forests are relatively scarce. Many have described light as a directing force in the distribution of resources among species; however, some such as soil nutriments have received less attention. In this paper is described the community structure of a mild-weather forest community along an altitudinal gradient of Tequila Volcano, in the state of Jalisco; the analysis was made according the α and β diversity, as well as soil variables relationships by ordination techniques, that explained 97 % of total variation; the most important variables were altitude, clay content, potassium, pH, electric conductivity, nitrites, sand, nitrogen, phosphorous and calcium. Tree richness showed a unimodal response in regard to altitude, with a maximum value between 2 000 a 2 350 m asl. Finally, the greatest species turnover rate occurs between the places with the highest altitude and those of the lowest (1.0). In Tequila Volcano there is a niche differentiation among species, which is due to the distribution of edaphic resources along the altitude gradient, which is acknowledged as the major mechanism that keeps the tree diversity in the temperate portion of the study area.


Hall (1987) wrote, "Hardly any fact about the United States economy is better established than the procyclical behavior of productivity." But in Basu and Kimball (1997), Basu, Fernald, and Kimball (1998), and in this paper, Basu and his coauthors (from here on Basu) argue that, correctly measured, technology shocks are not procyclical. They are very negatively correlated with inputs, including hours of work, and largely uncorrelated with output. A key element of Basu's papers is to instrument for cyclical fluctuations using variables arguably orthogonal to technology shocks. Papers by Gali (1998) and Kiley (1997) also conclude that technology shocks are very negatively correlated with inputs. But those authors identify technology shocks very differently, using structural restrictions on a VAR. It is interesting that these two sets of papers, with very different approaches, have similar results. Both sets of papers stress output-price stickiness as key to understanding the strong negative relationship between technology shocks and inputs. I first review Basu's exercise, asking whether it perhaps adjusts too much for procyclical factor utilization. My primary objective, however, is to test the conclusions of Basu, Gali, and Kiley that the negative correlation they find between inputs and their technology shocks is support for sticky prices.


Hierarchies of evolution equations associated with certain symmetric spaces are presented. Main examples of such symmetric spaces are Hermitian symmetric spaces and the obtained evolution equations include generalized nonlinear Schrodinger equations. Those results are obtained by extending the Lie algebra in the Ablowitz–Kaup–Newell–Segur scheme from sl(2,C) to more general one.


The paper presents an approach to Robust Model-Based System Engineering (RMBSE) applied to the design of the power system of a small-satellite. Tow simple low-fidelity parametric models of the power and telecommunication systems are used to compute the mass and power requirements for different orbital geometries. The low model fidelity implies that model and parameters are affected by epistemic uncertainty. This uncertainty is commonly captured by adding margins at subsystem and system level. In this paper instead, the effect of epistemic uncertainty is modelled with p-boxes on finite sets of values and propagated through the system models to compute the upper and lower expectation on the mass budget. A robust optimisation procedure is then introduced to find the design solution that minimises system mass and the impact of uncertainty.


Based on the RTT relation for a given rational $R$-matrix the {\em Yangian} and truncated {\em Yangian} are discussed. The former can be used to generate the long-range interaction models, whereas the latter can be related to the Goryachev-Chaplygin(GC) gyrostat. The trigonometric extension of the Goryachev-Chaplygin gyrostat has also been shown.


This article reports on a study of 444 homeless persons in Richmond, Virginia, that examined the relationships among homelessness and gender; current and past problems; and various demographic characteristics. The findings support the general theory that a significant proportion of homeless men and women drift down into their current situation after a history of crime, substance abuse, or mental illness. However, the path that leads to homelessness differs according to gender. Thus, men are likely to become homeless after years of crime and alcohol abuse, whereas women are likely to have taken the path of abusing nonprescription drugs. The implications of these findings for the development of policies and services are discussed from a feminist perspective.


Carsharing (hereafter CS) in Italy is getting importance as an alternative transport mode, that could contribute to a more sustainable urban mobility. Since 2000, thanks to Iniziativa Carsharing (ICS), the national coordination structure created to promote CS initiatives, many initiatives have been activated in several cities. The paper, after recalling the main characteristics of this service starting from the analysis of the literature on this topic, in the second part discusses the current situation of Milan's CS followed by the presentation of a brand new project of CS, called Green Move, promoted by Politecnico di Milano and funded by Lombardia Region. Green Move entails both the electric and peer to peer (hereafter P2P) dimensions in a CS project. In order to test the new service and to have a preliminary estimation of its attractiveness, a stated preference survey among Milan's citizens has been carried out. The very first results of this survey, concerning in particular the P2P dimension together with some policy considerations, are provided in the final part of the paper. To our knowledge, this represents the first attempt to estimate the potentiality of a P2P carsharing scheme through a specific market analysis.


The serum samples from a hundred healthy persons were assaied by Helena automatic rapid electrophoresis analyzer.It turned out that serum protein could be divided into five components: albumin, α 1 globulin, α 2 globulin, β globulin, γ globulin.When every datum group was statistically treated by medical evaluation system and the calculated data were expressed as ±s ,the results showed that the reference limits of every component percentage and A/G values,which were obtained by electrophoresis method,respectively were that:albumin(59.08±7.44)%, α 1 globulin(3.14±1.08)%, α 2 globulin( 8.49 ±4.06)%, β globulin(9.79+3.9)%, γ globulin(19.51±6.98)%,A/G values 1.47±0.42(while the reference limits of A/G values obtained by chemical method were 2.02±0.68).After a medical statistical analysis to every detected value,it was known that the reference limits of α 1 globulin, α 2 globulin, β globulin,and A/G values were of normal distribution and the others were not,and that the electrophoresis A/G values and chemical A/G values of every sample showed the significant difference of a non correlation under the test of T distribution ( r=0.768 3,P 0.000 1).


In this study I analyzed self-rated subjective well-being and multiple abilities of 1,200 Taiwanese kindergarten teachers who came from various backgrounds. Results showed that levels of social intelligence, practical intelligence, and teaching efficacy were significantly higher for the kindergarten teachers who were married than they were for the kindergarten teachers who were not married. In addition, kindergarten teachers who had religious beliefs scored significantly higher on the scale of subjective well-being than did those who had no religious beliefs. Furthermore, the results indicated significant relationships among teachers' multiple abilities and their subjective well-being.

This paper proposes to analyse the interrelation of two dynamics of territorial occupation based on American expansionism in an agroindustrial region of northwestern Mexico. The paper will analyze, from a longitudinal perspective, the colonization processes through economic development and the establishment of a Protestant religious model in the productive model and in the regional settlement of one of the most important agro-exporting zones of the northwest of Mexico. Despite limitations in the method, the work excels in connecting complex dynamics of globalization that are usually analyzed separately. The work shows the development of a colonial sense in the dynamics of territorial occupation of companies linked to agro-industry and the development of a Protestant religious field in the borders; at the same time, it identifies the dispute over the possession of a regional identity that has not remained untouched by conflicts between the local settlers.


Chilodonella hexasticha (Kiernik, 1909) was first recorded in Japan from the gills of a discus, Symphysodon discus Heckel, 1940, which is one of the tropical aquarium fishes. From the morphology of this ciliate species by SEM, its pathogenicity was discussed.


Abstract The newly developed SBSE-HPTLC/FLD method for analysis of PAH was focused on rapidness, cost-effectiveness, and the usage of more environmentally friendly, chlorine-free solvents. The sample preparation was streamlined and allowed 30 water samples to be extracted and analyzed within a routine working day. The validation showed that this method was reliable for control of the limit levels for benzo[a]pyrene (10 ng/L) and for the sum of benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[ghi]perylene and indeno[1,2,3-cd]pyrene (100 ng/L) in drinking, mineral, ground, or slightly to moderately contaminated surface water. Starting around the LOQ (0.08–0.44 ng/band depending on the PAH) the linearity showed coefficients of correlation ≥ 0.9920. The repeatabilities (%RSD, n = 3 at 10–58 ng/L depending on the PAH) using the same twister ranged between 0.4 and 6.3% and using 3 different twisters between 0.8 and 7.0%. Respective recoveries (n = 3) using the same twister were between 87–100% depending on the PAHs, using 3 different twisters between 77–103%. Moreover digital quantification proved to be a rapid and reliable alternative to conventional scanning.


A gate-drive circuit (10) is an interface between a clock (12) and control circuit (14) and a circuit (16) comprising an isolated gate bipolar transistor (IGBT) devices. The clock (12) provides two complementary clock signals (CLK1, CLK2) to the gate-drive circuit (10); the control circuit provides a signal (ENABLE) for turning the gate-drive circuit on and off, and the gate-drive circuit outputs isolated supply voltages (+RAIL, -RAIL), a drive signal (GATE), and a common reference signal (EMITTER). The control signal is sent across an isolation boundary via a 2-MHz push-pull converter in the gate-drive circuit (10). A transformer (T1) in the gate-drive circuit provides the isolation boundary. The power required to switch the IGBT device (16) is sent through the same 2-MHz converter. The secondary of the 2-MHz push-pull transformer (T1) is referenced to the IGBT emitter. As the primary side circuitry receives "on" signals from the control board (14), the converter runs and charges secondary-side bulk storage capacitors (C16, C18) in the gate-drive circuit. The gate voltage of the IGBT device is held off until the bulk storage capacitors are charged to a minimum value. When the capacitors have charged, the IGBT gate is turned on as the signal is received from the push-pull converter. The gate is then turned off by a negative voltage when the signal received from the converter is removed.

Large Language Models (LLMs), such as ChatGPT, LLaMA, GLM, and PaLM, have exhibited remarkable performances across various tasks in recent years. However, LLMs face two main challenges in real-world applications. One challenge is that training LLMs consumes vast computing resources, preventing LLMs from being adopted by small and medium-sized enterprises with limited computing resources. Another is that training LLM requires a large amount of high-quality data, which are often scattered among enterprises. To address these challenges, we propose FATE-LLM, an industrial-grade federated learning framework for large language models. FATE-LLM (1) facilitates federated learning for large language models (coined FedLLM); (2) promotes efficient training of FedLLM using parameter-efficient fine-tuning methods; (3) protects the intellectual property of LLMs; (4) preserves data privacy during training and inference through privacy-preserving mechanisms. We release the code of FATE-LLM at https://github.com/FederatedAI/FATE-LLM to facilitate the research of FedLLM and enable a broad range of industrial applications.

Supplemental Digital Content is available in the text. Background. Few reports have focused on newer coronavirus disease 2019 (COVID-19) therapies (remdesivir, dexamethasone, and convalescent plasma) in solid organ transplant recipients; concerns had been raised regarding possible adverse impact on allograft function or secondary infections. Methods. We studied 77 solid organ transplant inpatients with COVID-19 during 2 therapeutic eras (Era 1: March–May 2020, 21 patients; and Era 2: June–November 2020, 56 patients) and 52 solid organ transplant outpatients. Results. In Era 1, no patients received remdesivir or dexamethasone, and 4 of 21 (19.4%) received convalescent plasma, whereas in Era 2, remdesivir (24/56, 42.9%), dexamethasone (24/56, 42.9%), and convalescent plasma (40/56, 71.4%) were commonly used. Mortality was low across both eras, 4 of 77 (5.6%), and rejection occurred in only 2 of 77 (2.8%) inpatients; infections were similar in hypoxemic patients with or without dexamethasone. Preexisting graft dysfunction was associated with greater need for hospitalization, higher severity score, and lower survival. Acute kidney injury was present in 37.3% of inpatients; renal function improved more rapidly in patients who received remdesivir and convalescent plasma. Post–COVID-19 renal and liver function were comparable between eras, out to 90 d. Conclusions. Newer COVID-19 therapies did not appear to have a deleterious effect on allograft function, and infectious complications were comparable.

Parentage analysis has been used to evaluate pollen dispersal in Kopyor coconut (Cocos nucifera L.). Investigations were undertaken to elucidate (i) the dispersal of pollen, (ii) the rate of self and outcrossing pollination, and (iii) the distance of pollen travel in Pati kopyor coconut population. The finding of this activities should be beneficial to kopyor coconut farmers to increase their kopyor fruit harvest and to support breeding of this unique coconut mutant. As many as 84 progenies were harvested from 15 female parents. As many as 95 adults coconut provenances surrounding the female parents were analyses as the potential male parents for the progenies. The adult coconut palms were mapped according to their GPS position. All samples were genotyped using six SSR and four SNAP marker loci. Parentage analysis was done using CERVUS version 2.0 software. Results of the analysis indicated that evaluated markers were effective for assigning candidate male parents to all evaluated seedlings. There is no specific direction of donated pollen movement from assigned donor parents to the female ones. The donated pollens could come from assigned male parents in any directions relative to the female parent positions. Cross pollination occured in as many as 82.1% of the progenies analyzed. Outcrossing among tall by tall (TxT), dwarf by dwarf (DxD), hybrid by hybrid (HxH), TxD, DxT, TxH, DxH, and HxD were observed. Self-pollination (TxT and DxD) occurred in as many as 17.9% of the progenies. The dwarf coconut was not always self pollinated. The presence of DxD, TxD, and HxD outcrossing was also observed. The donated pollens could come from pollen donor in a range of at least 0-58 m apart from the evaluated female recipients. Therefore, in addition to the wind, insect pollinators may have played an important role in Kopyor coconut pollination.


PROBLEM TO BE SOLVED: To provide a ground improvement method which enables the quality of a solidification improvement body to be checked during establishment of the solidification improvement body and which can establish a predetermined solidification improvement body by mixing and agitating again when a defective point of the quality is confirmed.SOLUTION: In a ground improvement method, as an agitation shaft 5 having an agitating blade 6 and a discharge port 8 installed on the tip side is penetrated or extracted, the agitating blade 6 is rotated while a solidification material is discharged from the discharge port 8, and a natural ground and the solidification material are mixed and agitated by the agitating blade 6 so as to establish a solidification improvement body in the ground. In the ground improvement method, a small-sized measuring apparatus 10 for measuring specific resistance of a solidification improvement body to be established in the ground is attached to the agitating blade 6 and data of specific resistance measured by the small-sized measuring apparatus 10 is transmitted to the ground. On the basis of the transmitted data of specific resistance, the quality of the solidification improvement body is checked, and when a defective point of the quality of the solidification improvement body is confirmed, mixing and agitating are performed while a solidification material is discharged or is not discharged in the defective point.SELECTED DRAWING: Figure 3

The energy difference (ΔE) between the two types of rotamers of β-methoxyethylmercuric chloride has been satisfactorily determined by only assuming the ratio of vicinal trans and gauche HH coupling constants. The validity of the result was confirmed by the large temperature dependence of the vicinal HgH couplings in various solvents. Moreover, it has become possible to determine small values of ΔE in nonpolar solvents. Two ΔE values of β-methoxypropylmercuric chloride in various solvents were determined on the basis of the substituent electronegativity effect on the HH couplings and their validity was supported by the large temperature dependence of the vicinal HgH couplings. With regard to erythro- and threo-(α-methyl-β-methoxy)propylmercuric chlorides, both the HH and HgH couplings were used to estimate the values of ΔE among the rotamers. Throughout the mercury compounds, it was ascertained that the more polar the solvent, the greater the preference for the conformation with the trans disposed HgCl and OCH3 groups. Excellent agreement between the observed facts and the calculations by extended Huckel theory were shown with regard to the relative magnitude of the rotamer polarity and the conformational energy difference of these mercury compounds.

Personnel management in the digital industry has become inextricably linked with open innovation, as a greater emphasis is placed on finding talents best suited for a specific company and on controlling the situation in the rapidly changing environment. In this context, it is important to bridge the current gap in the literature, understanding how introducing innovative approaches in personnel management allows to support simultaneous complex processes, finding the parameters required for performance assessment and forecasting. The goal of the article is to consider multiple options of personnel management metrics, outlining their strengths, weaknesses and opportunities, and present the suitable dashboard with the most appropriate indicators. We propose an innovative tool that can help managers at different levels to effectively handle diverse scenarios of personnel performance. We have formulated the criterion for choosing most appropriate innovative personnel management digital dashboard, investigating various metrics and KPI which should be chosen to assess the company's current situation in terms of personnel management. We present an example of the dashboard, which is a ready solution that can be adapted to the specific company environment. A detailed modification of the proposed digital dashboard for personnel management based on the fundamental approach to engineering incorporating open innovation could be a topic for a further research.


Topographic phase simulation is important for deformation estimation in differential synthetic aperture radar (SAR) interferometry. The most commonly used 30 m resolution shuttle radar topography mission (SRTM) digital elevation model (DEM) is usually required to be resampled due to its relatively low resolution (LR) comparing to the high resolution (HR) SAR images. Although the WorldDEM with a 12 m resolution achieves global coverage, it is not available freely. Consequently, it is useful to evaluate the practicability of the super-resolution (SR) from LR SRTM DEMs to HR WorldDEM ones, which has not been investigated. Most existing DEM SR models are trained with synthetic datasets in which the LR DEMs are downsampled from their HR counterparts. However, these models become less effective when applied to real-world scenarios due to the domain gap between the synthetic and real LR DEMs. In this article, we constructed a real-world DEM SR dataset, where the LR and HR DEMs were collected from SRTM and WorldDEM, respectively. An enhanced SR generative adversarial network model was adapted to train on the dataset. Considering that the real LR-HR pairs may suffer from misalignment, we introduced the perceptual loss for better optimizing the model. Moreover, a logarithmic normalization was proposed to compress the wide elevation range and adjust the uneven distribution. We also pretrained the model using natural images since collecting sufficient HR DEMs is costly. Experiments demonstrate that the proposed method achieves near 0.69 dB improvement of peak signal-to-noise ratio. In addition, our method is also validated to improve the topographic phase simulation by 23.42% of MSE.


In recent years we have observed a more and more intensive capital expansion of Chinese companies. A manifestation of this process are the acquisitions of European companies whose value and number is constantly growing. The main objective of Chinese investment in Europe is gaining access to production technology that is in the possession of advanced companies. This is necessary in connection with the reforms currently undertaken by the Chinese authorities. An important motive of acquisitions is also the desire of acquiring well-known brands, in order to improve the image of the products manufactured in China. Together with the increase of the value and number of acquisitions of European enterprises, there is a visible diversification of sectoral activities of the acquired businesses. This may be a sign of a positive trend and indicate a high potential of Chinese investors. Despite the fact that companies from the Middle Kingdom are new players on the European foreign investment market, for many crisis-ridden companies from western countries they are an important source of capital necessary for further operation.

According to the international criteria for the classification, if a country over the age of 60 or over the age of 65 if the proportion of the elderly in the total population of 10% or more than 7%, the result can be achieved as the aging of the population. The momentum of China's aging population caused concern around the world. When the bell sounded to the 21st century, China has entered the aging of the population-the country. At present, China's elderly population is 130 million, accounting for one fifth of the world's elderly population, and continues to increase at an average annual rate of 3.2%. It is expected that in 2010, China's elderly population will reach 230 million. To 2040, the country's aging population will reach 400 million, accounting for one-fourth of the total population. Industry is about the old building of a harmonious society, maintaining social stability and carries forward the fine traditions of the great cause imminent.

We apply the standard radio pulsar rotating vector model to the white dwarf (WD) pulsar AR Sco's optical polarization position angle swings folded at the WD's spin period as obtained by Buckley et al. Owing to the long duty cycle of spin pulsations with a good signal-to-noise ratio over the entire spin phase, in contrast to neutron star radio pulsars, we find well-constrained values for the magnetic obliquity α and observer viewing direction ζ with respect to the spin axis. We find and , implying an orthogonal rotator with an observer angle . This orthogonal nature of the rotator is consistent with the optical light curve consisting of two pulses per spin period, separated by 180° in phase. Under the assumption that ζ ≈ i, where i is the orbital inclination, and that the companion M star is Roche-lobe-filling, we obtain for the WD mass. These polarization modeling results suggest the that nonthermal emission arises from a dipolar WD magnetosphere and close to the star, with synchrotron radiation (if nonzero pitch angles can be maintained) being the plausible loss mechanism, marking AR Sco as an exceptional system for future theoretical and observational study.


Objective:Study the relation of distracting force and distracted intervertebral height.To testify the method of judging the appropriate distracting height by the distracting force during anterior cervical surgical approach.Method:6fresh cadavertic cervical specimens were measured of its resistant force to distracting by using torsion displayable retractor.Analysis and compare the results.Result:The distracting torsion increased smoothly at first and dramatically when intervertebral space was entirely distracted.Cutting the different ante-rior structure only reduce the torsion value but could not change its variation pattern,except cutting the yellow ligament which showed no more increase in torsion.Conclusion:After anterior cervical decompression was com-pleted,the marked increased distracting torsion was due to the strain of the yellow ligaments.It is feasible to judge the proper intervertebral height by distracting torsion variation.


During the end of August 2013, a massive fish mortality occurred in Ismarida Lake, a small and shallow system of northern Greece, where approximately 10-18 tons of euryhaline fish died. This study attempts to describe the fish kill that occurred in Ismarida Lake during the night of 28 August 2013, and to identify the possible drivers that may have triggered this event. Combined hydrographic, ichthyological and phytoplankton surveys were carried out with a toxicological analysis. The study proposes both short-term and long-term measures for the management of both quality and quantity of the water (ground and surface) resources in the broader basin of Ismarida Lake.


Water level in rivers, lakes and reservoirs has great influence on the interactions between prey and predator fish. Indeed, the increase of the water volume hinders the capture of the prey by the predator. The same reasoning applies when there is a decrease in the volume of water, favoring the capture of the prey by the predator. In this paper, we consider a seasonally varying predator–prey model to study the influence of water-level variations on the interaction between two species of fishes in an artificial lake. A seasonal variation of the water-level is introduced in the predation rate taking into account two values, leading to a general switched system. Permanence, stability and existence of an invariant domain containing at least one periodic solution are established. Our theoretical results confirm the assumption that the water exerts a strong influence on the interaction between fishes.


A one-pot synthesized persimmon tannin (PT)-based novel biosorbent modified with 2,5-dimercapto-1,3,4-thiadiazole (DMTD) was prepared for the selective adsorption of Au from aqueous mixtures. The synthesized biosorbent was designated as DMTD-PT and characterized using elemental analysis, zeta potential, Fourier transform infrared (FTIR) spectroscopy and X-ray photoelectron spectroscopy (XPS). The batch adsorption experiments in a model electronic waste leachate revealed that both DMTD-PT and PT had poor affinity for coexisting base metal ions, however, DMTD-PT and PT adsorbed 97.7 and 32.7%, respectively, of Au with an initial Au concentration of 78.0 mg L in the mixtures with a dosage of 2.5 g L each at pH 3.0 at ambient temperature. The adsorption results indicate the superior selectivity of DMTD-PT for Au compared to that of PT. The continuous column experiments further proved that DMTD-PT can be used to separate Au from aqueous mixtures. The maximum adsorption capacity of DMTD-PT for Au was determined to be 0.42 mmol g. A kinetic study in combination with XPS and FTIR analyses of fresh and spent DMTD-PT further revealed that the potential biosorption mechanism can be attributed to the collaboration of electrostatic interactions and coordination.

Bone tissue engineering is a very challenging and promising field, which handles with the limitations of bone regenerative capacity and the failure of current orthopedic implants [1]. This work describes the preparation and characterization of an injectable dextrinbased hydrogel (oDex) through dextrin oxidation followed by cross-linking with a dihydrazide [2]. In vitro and in vivo experiments allowed to conclude that this system can carry and stabilize cells, nanogels, Bonelike® granules [3] and other biomolecules. This is a promising biomaterial due to its biocompatibility, and potential to promote an adequate environment for bone regeneration, which was increased by the combined bioactive molecules. Its injectability allows a minimal invasive surgical procedure with decreased patient morbidity, lower infection risk and reduced scar formation. Furthermore, an adequate sterilization protocol for this kind of material was established. The tight collaboration between University of Minho and Bioskin S.A. company, envisioning technology transfer and product valorization, has resulted in a published international patent of the product (WO2011070529A2) [4]. Currently, the submission of a request for the authorization for the clinical trials is being planned.

In this article, we have proposed a novel dispersion decreasing fiber (DDF) which is incorporated with saturable nonlinearity, for the analysis of supercontinuum generation. The proposed DDF finds boundless ways for achieving desired bandwidth profile by exploiting suitable value of saturable nonlinearity with the change in power. This approach is relatively a simple way to achieve desired bandwidth profile rather than using different fiber for specific requirement.


The utility model relates to a novel sealed flange type eccentric butterfly valve, which is provided with sealed pairs on a valve body and a valve plate. The sealed part of the valve body is made into a frame platform in a shape like the Chinese character 'tu', two end surfaces of the valve body are provided with O-shaped seal rings, and an inner n-shaped stainless steel ring band is inlaid in the frame platform in a shape like the Chinese character 'tu' of the valve body to form the seal of the valve body. Simultaneously a T-shaped rubber ring is pressed in a slot of the valve plate via a press ring and a fastener to form the seal of the valve plate, and thus the sealed pairs of the valve body and the valve plate are formed. The best sealed effect can be obtained via the simple O-shaped rubber ring in order to solve the sealed problem between a convex platform of the valve body and the n-shaped steel band. Roll forming technology is adopted in order to replace traditional nickel and phosphorus brushing and plating technology, noble materials are saved, production processing is simplified, and cost is reduced. The valve has the advantages of compact and reasonable structure and high erosion resistance. The utility model having long service life can be used for equipment for adjusting water supply and drainage and interception in a system.

At least one different component to iron is thereby removed from the iron silicate stone. The processed iron silicate stone is used for the production of pig iron or steel. The device for recovery of the treated silica rocks is designed as a device for the production of pig iron or steel.


Recent research on artificial neural network models regards as relevant a new characteristic called biological plausibility or realism. Nevertheless, there is no agreement about this new feature, so some researchers develop their own visions. Two of these are highlighted here: the first is related directly to the cerebral cortex biological structure, and the second focuses the neural features and the signaling between neurons. The proposed model departs from the previous existing system models, adopting the standpoint that a biologically plausible artificial neural network aims to create a more faithful model concerning the biological structure, properties, and functionalities of the cerebral cortex, not disregarding its computational efficiency.

This book has proved to be both timely and a valuable asset for educators and policy makers at the beginning of the twenty-first century. The area of democratic and citizenship education has become increasingly important over the past decade, reflecting the need of emergent democracies to address how they will educate their first generation of citizens living in a democracy. Since the symbolic demise of Communism in Europe, the fall of the Berlin Wall in 1989, more than 40 new democracies and quasi-democracies have emerged. They have, as a common theme, the perceived urgent need to educate their children in the ways of democracy. In large measure this task falls to the formal curriculum, schools and education systems. For these educators and policy makers the application of democratic concepts, processes and values to the curriculum is an essential starting point. This book helps meet that need in an eminently readable manner. The publication of this book is also timely for those established democracies, such as England, the USA and Australia, as well as newer democracies such as France, Germany and Italy, which are reflecting on their democratic condition and how best to engage an increasingly disenchanted youth (Putnam, 2000; Bennett, 2000). Through numerous inquiries, reviews and studies in the 1990s, concern has been raised about the condition of public education of future citizens and proposals forwarded as to what directions democratic education might take. The United States (National Commission on Civic Renewal, 1998; Lutkus et al., 1999), England (Advisory Committee on Citizenship, 1998), and Australia (Civics Expert Group, 1994; Kemp, 1997) experienced a review of national assessment, as well as a government policy initiative, on how democratic processes might be sustained through educational programmes. Given that a primary goal of citizenship education in schools is to prepare the next generation of citizens for both democratic enlightenment and political engagement, the declining understanding and participation in the democratic process by young people is all the more problematic (Putnam, 1995, 2000; Bennett, 2000; Torney-Purta et al., 2001). Policy-makers, politicians and educators have looked to the education system to find ways to engage young people as active participants in their democracies. As there are now over 120 democracies and 'intermediate' or quasidemocracies worldwide, accounting for nearly 70% of the world's population, the relationship between schooling and educating democratic citizens is of vital importance. This book meets that need in two essential ways. First, in the context of school education, it provides a clear understanding of the concepts, principles and processes instrumental in education for democratic citizenship. Second, it draws upon a variety of examples of applied education for democratic citizenship from international sources. In addressing the need to understand the nature of democracy and education for democratic citizenship, the book is a valuable guide to those who will reflect, devise, or revise civics and citizenship education programmes. The editors split the first five chapters between themselves. Patrick addresses concepts at the core of education for democratic citizenship. He argues that a global revival in civic education is occurring through education for democratic citizenship, which in turn affects the nature and presentation of social studies in schools. This reflects the

Exosomes are extracellular vesicles with a diameter of 40-100 nm. Exosomes are found in many body fluids, including milk. Milk is a unique source of exosomes since the collection of this biological fluid is non-invasive, and animals can produce several liters of milk per day. Cow's milk cannot be used to isolate biologically active components with therapeutic potential due to the risk of transmission of prion diseases. In this regard, horse milk is a unique source of exosomes that can be used for targeted delivery.

I n spectral computed tomography (CT), multiple spectrally distinct attenuation data sets are obtained from the same scan, which enables material composition analysis not possible with conventional CT. Dual-energy CT (DECT), where a low and high energy data set are obtained, is currently available in clinical practice using the following approaches: a) Dual source technology: two x-ray tube/detector systems separated by approximately 90 o and operated at different tube potentials (1) (Fig. 1a); b) Rapid tube potential switching technology: the potential applied across a single x-ray tube is switched rapidly between a high and low setting (1, 2) (Fig. 1b); c) Dual-spin technology: the same anatomical region is scanned twice during two consecutive rotations, once with a high potential applied across the x-ray tube and once with a low potential applied (1) (Fig. 1c); d). Split-beam technology: the spectrum emitted from a single tube is split into high and low energy spectra (3). Spectral detector CT (SDCT) (IQon, Philips Healthcare) is a novel technology introduced for clinical DECT data acquisition. A single potential is applied across a single x-ray tube and two layers of detectors separate low and high energy data: the top layer absorbs low energy photons and the bottom layer absorbs high energy photons (Fig. 1d). In addition to conventional (polyenergetic) images, projection data simultaneously obtained from both detector layers can also be utilized to generate spectral images. The spectral images useful for cardiovascular assessment include virtual monoenergetic images (Fig. 2a), iodine density maps (Fig. 2b), virtual unenhanced images (Fig. 2c), and effective atomic number (Z effective) images (Fig. 2d). An important feature of SDCT technology is that spectral information is available in all patients without a priori selection of a special protocol or exposure to additional radiation. Images are available at full field-of-view and a minimum rotation time of 0.27 seconds (s) with complete temporal and spatial registration. In this paper, we present our initial clinical experience based on the acquisition of data from over 200 patients who underwent cardiovascular studies (i.e., cardiac, aorta, pulmonary veins, pulmonary arteries) using SDCT including the impact of this technology on radiation dose and contrast dose. The creation of spectral images from spectral data is discussed and the utility of these images is demonstrated for specific cardiovascular applications. ABSTRACT Spectral detector computed tomography (SDCT) is a novel technology that uses two layers of detectors to simultaneously collect low and high energy …


Subspecies of partially decarbonylated molybdenum hexacarbonyl supported on silica were studied by diffuse reflectance IR spectroscopy. Mo(CO)[sub 6]/SiO[sub 2] was prepared in a fluidized bed reactor by vapor-phase adsorption of molybdenum hexacarbonyl under nitrogen flow. Decarbonylation begins when Mo(CO)[sub 6] has adsorbed onto the silica. Dehydroxylation of the support during calcination facilitates the formation of subspecies of Mo(CO)[sub 6]. The activation energy needed for bond formation between a transition metal and silica and for decarbonylation is lower than the desorption energy of physisorbed Mo(CO)[sub 6], and this was seen in the IR spectra as a disappearance of bands due to subspecies. When the supported Mo(CO)[sub 6] was reheated the physisorption bands were the last to disappear from the IR spectra. 37 refs., 6 figs., 2 tabs.


We report on a common fragment ion formed during the electron-ionization-induced fragmentation of three different three-ring polycyclic aromatic hydrocarbons (PAHs), fluorene (C13H10), 9,10-dihydrophenanthrene (C14H12), and 9,10-dihydroanthracene (C14H12). The infrared spectra of the mass-isolated product ions with m/z = 165 were obtained in a Fourier transform ion cyclotron resonance mass spectrometer whose cell was placed inside the optical cavity of an infrared free-electron laser, thus providing the high photon fluence required for efficient infrared multiple-photon dissociation. The infrared spectra of the m/z = 165 species generated from the three different precursors were found to be similar, suggesting the formation of a single isomer. Theoretical calculations using density functional theory (DFT) revealed the fragment's identity as the closed-shell fluorenyl cation. Decomposition pathways from each parent precursor to the fluorenyl ion are proposed on the basis of DFT calculations. The identification of a single fragmentation product from three different PAHs supports the notion of the existence of common decomposition pathways of PAHs in general and can aid in understanding the fragmentation chemistry of astronomical PAH species.

The recent recognition of cyclically laminated tidal rhythmites provides a new approach to tracing the dynamic history of the Earth-Moon system. Late Proterozoic (-5650 Ma) elastic rhythmites in South Australia represent an unsurpassed palaeotidal record of -560 years' duration that provides numerous palaeorotational parameters. At -5650 Ma there were 13.1+-0.1 lunar months/year, 400+-7 solar days/year, and 30.5+-0.5 solar days/lunar month. The lunar apsides and lunar nodal cycles were then 9.7+-0.1 years and 19.5+-0.5 years, respectively. The indicated mean Earth-Moon distance of 58.28+-0.30 Earth radii at -5650 Ma gives a mean rate of lunar retreat of 1.95+-0.29 cm/year since that time, about half the present rate of lunar retreat of 3.7+-0.2 cm/year obtained by lunar laser ranging. The rhythmite data imply a substantial obliquity of the ecliptic at -5650 Ma, and indicate virtually no overall change in the Earth's moment of inertia, which militates against significant Earth expansion since -5650 Ma. Early Proterozoic (-52, 500 Ma) cyclic banded iron-formation in Western Australia, that may record submarine fumarolic activity triggered by earth tides, suggests -514.5+-0.5 lunar months/year and a mean Earth-Moon distance of -554.6 Earth radii at -52, 500 Ma. The combined rhythmite data suggest a mean rate of lunar retreat of -51.27 cm/year during the Proterozoic (-52, 500-650 Ma); the indicated increasing mean rate of lunar retreat since -52, 500 Ma is consistent with increasing oceanic tidal dissipation as the Earth's rotation slows. A close approach of the Moon during earlier time is uncertain. Continued study of tidal rhythmites promises to further illuminate the evolving dynamics of the Earth-Moon system.


is near ly normal (86 °) to the associated uranyl axis. The distances and bond angles within the group agree well with those observed in other acetates. The crude experimental determinat ion of the hydrogen coordinates places the H m a tom in the same plane as the carbon and oxygen atoms, and this feature was re ta ined in modifying the exper imental coordinates for the hydrogen atoms so as to give more reasonable C H distances and bond angles. H 0 distances outside a given aceta te group are all greater t h a n 2-7 /~, showing tha t there is no real bonding. The 0m--0~v distances are 2.21+0.05 /~ within and 2-76±0-05/~ between aceta te groups. These are alterna t ing edges of the near ly plane hexagon of oxygen atoms about the uran ium a tom shown in :Fig. 2.


A simple formulation for designing fixed order dynamic compensators which are robust to both uncertainty at the plant input and structured uncertainty in the plant dynamics is presented. The emphasis is on designing low order compensators for systems of high order. The formulation is done in an output feedback setting which exploits an observer canonical form to represent the compensator dynamics. The formulation also precludes the use of direct feedback of the plant output. The main contribution lies in defining a method for penalizing the states of the plant and of the compensator, and for choosing the distribution on initial conditions so that the loop transfer matrix approximates that of a full state design. To improve robustness to parameter uncertainty, the formulation avoids the introduction of sensitivity states, which has led to complex formulations in earlier studies where only structured uncertainty has been considered.


The use of the word 'biodiversity' has increased dramatically in the last decade in the popular press, governmental and intergovernmental reports, scientific papers and meetings. Here I discuss the challenge around operationalizing the concept of biodiversity to enable its incorporation into scientific theory. Multiple dimensions, levels of organization and components have been organized to create a conceptual framework were biodiversity research revolves. As an example, I describe how research on the functional dimension of biodiversity has developed and how concepts and theory have emerged along the way.  The degree to which some overall level of biodiversity is required for the delivery of ecosystem services is still unknown. In this sense, the essential issue that has fuelled biodiversity research is yet unresolved. However, in a couple of decades of intensive research, the formalization of the theory behind the theory has progressed substantially. Key words: Biological diversity, ecological science, operationalization, conservation science.


A particularly important question is which of the various jobs that tend to be lumped together under the term "housework" is decisively important to the housewife, or in other words, what exactly is the part of housework that "defines one as a housewife?". If one look at it in this sense, then the following issues arise. The first point is the externalization of housework. The second point is the existence or otherwise of a public system for activities related to reproduction. The third aspect is the existence of immediate family members, relatives, and a neighborhood network. This chapter attempts to consider the above points using the example of housewives and housework in contemporary urban middle-class India. It focuses particularly on the division and "ranking" of different tasks in housework, and looks at the roles and division of labor between the "housewife", "family members", and "domestic servants" based on this ranking. Keywords: housewife; housework; India; urban middle-class

Because of the ways in which the responses of financial institutions in the UK to the need for capital have evolved over many decades, and the consequent dependence of small businesses upon bank loans or other forms of borrowing, Britain has been a late developer in the private venture capital arena. The situation is now perceptibly changing, and new avenues are opening for smaller opportunities to attract private capital. The venture capital industry has been accused of surrounding the process of matching supply and demand with jargon and mystique, and successive layers of statutory regulation have done nothing to help, but the air is clearing through democratisation and openness. `Effectiveness' and `appropriateness' are, however, as always of fundamental importance. The paper examines the issues to be faced by the engineering entrepreneur wishing to launch or expand his business using private capital. Frankness and clear thinking are the essential virtues in the search for venture partnerships, and the entrepreneurial engineer should be able to display them readily enough. The paper briefly reviews all funding routes before considering the steps to be taken to maximise the chances of success in the search for private capital. The main issues and processes are addressed, and the pitfalls examined. (6 pages)


As the population increases gradually, the number of automobiles are also increasing and this leads to many accidents and traffic congestions. In this busy world, people always use to park vehicles at restricted or no parking zones. When a vehicle has been parked at no parking area, the road gets narrowed and cause traffic congestion. Large number of traffic police are deployed to check the illegal parking and fine the owners so that they would not park again in no parking zone, but it's not successful solution. Therefore, various technologies has been used for the detection of the vehicles which are parked at no parking zone. In this paper, a detailed a survey on various detection methods and control measures is performed.


In the current trends globally, the excessive utilization of the energy and overconsumption of fuel has resulted in the global warming and environmental pollution. The Absorption cooling offers the possibility of using heat to provide cooling. For cooling purpose the required heat input is obtained from the excessive heat of the boiler or from non conventional power sources like solar energy. NH3-H2O system ammonia used as a refrigerant and water is used as an absorbent, these two liquids served as standard and a refrigerant cycle is produced. The system VARS in environment friendly and does not deplete the atmosphere. Thus it is essential to create awareness in the world for this system for it is an alternative system which is more environmental friendly. The objective of this paper is to present empirical relations for evaluating of the performance of a single stage vapor absorption system.
