Cranberries contain high levels of health‐promoting anthocyanins, which have been implicated in their potential role in the prevention of cardiovascular disease. The objective of this study was to determine the effects of cranberries on lipid and lipoprotein metabolism in mice expressing human apolipoprotein A‐I transgene (hApoAITg), which have similar HDL metabolism to that of humans. Male hApoAITg mice were fed a modified AIN‐93M high fat/high cholesterol control diet (HF/HC; 15% fat, 0.25% cholesterol, w/w; n = 15) or a HF/HC experimental diet supplemented with 5% (w/w) dried, whole cranberry powder (n = 16) for 8 weeks. Subsequently, the mice were sacrificed to obtain tissue and blood samples. There were no significant differences in terminal body weights, body weight gain, liver weights and epididymal fat weights between control and cranberry‐fed mice. Serum total cholesterol (TC) and apolipoprotein B cholesterol (ApoB‐C) levels were significantly lower in controls than cranberry group (238 ± 9.4 vs. 294 ± 20.3 mg/dL for TC; 43.9 ± 6.7 vs. 88.3 ± 15.0 mg/dL for ApoB‐C) with no significant difference in serum high‐density lipoprotein cholesterol (HDL‐C) concentrations. Serum triglyceride (TG) levels of cranberry group (55.5 ± 4.6 mg/dL) were also significantly higher than controls (37.7 ± 2.9 mg/dL). Hepatic expression of sterol‐regulatory element binding protein 2 and low‐density lipoprotein receptor was significantly lower in cranberry group, which may be responsible for the increased serum TC and apoB‐C, while HMG‐CoA reductase and proprotein convertase subtilisin/kexin type 9 mRNA levels were not different between two groups. Despite the significant increase in serum TG in mice‐fed cranberries, their mRNA abundance of genes responsible for lipogenesis (e.g., fatty acid synthase and stearoyl CoA desaturase) and fatty acid oxidation (e.g., carnitine palmitoyl transferase 1α and acyl‐CoA oxidase 1) was not significantly altered in the liver. In addition, the hepatic expression of genes involved in HDL metabolism, including human apoA‐I, lecithin:cholesterol acyltransferase, and scavenger receptor class B, type I, was significantly lower in cranberry‐fed mice compared with controls although serum HDL‐C levels were not different between two groups. Further study should be warranted to have better mechanistic insight into the changes in lipid and lipoprotein metabolism by cranberries.


Consider the FitzHugh–Nagumo system $u_t = \sigma v - \gamma u$, $v_t = \Delta v + f(v) - u$ on a space-time domain $\Omega \times (o,T)$, subject to initial values $u_0 ,v_0 $ and a Neumann boundary condition for $\partial v/\partial \nu $ on $\partial \Omega $. This model describes the transmission of electrical impulses in the nervous system; f is typically a cubic polywm-nomial and $\sigma > 0,\gamma \geqq 0$. In this paper we reduce the solution to the determination of solutions of recursively generated Neumann problems over $\Omega $ via the semidiscretization $(u_m - u_{m - 1} )/\Delta t = \sigma v_{m - 1} - \gamma u_m$, ${{(v_m - v_{m - 1} )} / {\Delta t}} = \Delta v_m + f(v_m ) + u_m $. Here, for $M \geqq 1,\Delta t = T/M$ and $m = 1, \cdots ,M$. Approximations $U^M $ and $V^M $ are constructed by piecewise linear interpolation in t, at $t_m = m\Delta t$, of the functions $u_m ,v_m $, respectively. The sequences $\{ U^M \} $ and $\{ V^M \} $ are shown to converge to $(u,v)$


A significant body of research has established an association between maternal depressive symptoms and parenting. The current study tested the possible moderating role of marital quality and child negative emotionality (NE) from 9 to 27 months among a sample (n = 561) of adopted children and their mothers. Although the data revealed direct associations between depressive symptoms, marital quality, child NE, and parenting behavior, moderation was not evident with the exception of two marginal trends. We found no evidence that marital quality moderated the association between maternal depressive symptoms and warm parenting and only weak evidence that marital quality moderated the association between depressive symptoms and harsh parenting. Similarly, we found no evidence that child NE moderated the association between maternal depressive symptoms and warm parenting and only weak evidence that child NE moderated the association between depressive symptoms and harsh parenting. The direction of effects for marginal moderated trends was unexpected and counter to our hypotheses. Theoretical relevance and implications for clinical practice are discussed.


Abstract A dual-sensor system is developed to measure the density and viscosity of polymer melts, simultaneously, during extrusion process. The sensory system utilizes a 2.25 MHz longitudinal ultrasound transducer in conjunction with a 2.25 MHz shear type ultrasound transducer, placed in a modified extrusion die. The acoustic impedance of the polymer melt, corresponding to the longitudinal ultrasound waves (UTL), is used to measure the density of the polymer melt using established physical models. While, the acoustic impedance of the shear waves (UTS) is used to measure the viscosity of the polymer melt, utilizing the density measurements obtained by the longitudinal ultrasound transducer. The system was evaluated using polyvinyl chloride compounds containing various levels of foaming agent and processing aid at fixed processing conditions. The system measurements of the melt density was compared to the density of the extrudate, while the viscosity measurements were compared to the calculated values using slit-rheometry equations. The correlation coefficients between the ultrasound sensor and actual measurements were in the range of 92% and 96% for the melt density and viscosity; respectively.

The history of GSR Classical conditioning studies on the optimal CS-UCS interval has been evaluated in the context of the phenomena of internal inhibition of delay HD, an effect of delayed reinforcement. It was concluded from this review that nearly all GSR studies concerned with this theoretical issue lack validity since responses to stimulus onset orienting and unconditioned responses and not delayed conditioned responses have been the subject of measurement. The existence of an "optimal" CS-UCS interval is questionable, however, and appropriate experimental methodology is suggested for the solution of this problem.

The role of temporal processes in classical conditioning has been emphasized and the concept of "precision" in neural timing mechanisms mediating delayed CRs has been advanced. It is suggested that the neural temporal properties of the conditioning process have greater heuristic value than the intensity properties of the conditioned response.


The purpose of this study was to determine the application of the Discovery learning model to increasing student interest in learning and learning outcomes. This type of experimental research involved 40 students of SMA Negeri 11 Tana Toraja. Using observational data collection to assess interest and test questionnaires to measure learning outcomes. The data analysis technique used is descriptive statistical analysis. The results of the study (1) The application of conventional learning models to students has not been able to increase student interest and learning outcomes. 2) The application of the discovery learning model in biology subjects to students can increase student interest in learning and student learning outcomes. This proves that the discovery learning model is a good learning model and can be the teacher's choice to increase student interest in learning and learning outcomes.


Two trials were conducted with Nicholas strain turkeys. In trial 1, 300 male poults were reared to 49 days using either initial stages of 'large-turkey' feeding regime, or a situation allowing for diet self-selection of protein and energy. Within these programs, diets were supplemented with 10 ppm avoparcin, while a comparable number of controls received no growth promoter. Avoparcin improved growth rate (P < 0.01) irrespective of age, and improved feed utilization to 35 days of age. This effect was not confounded with the form in which diets were offered. In a second trial a 'broiler-turkey' feeding schedule was used, with birds slaughtered at 88 days. Diet treatments consisted of a control diet containing 33 ppm robenz and test diets containing either 33 ppm robenz + 10 ppm avoparcin or 10 ppm avoparcin alone. Avoparcin improved weight gain (P < 0.05) irrespective of coccidiostat inclusion. Feed utilization and carcass grades were not influenced by diet. The 7% improvement in body weight noted here with...


Salviano of Marsiglia, in two passages of De Gubernatione Dei, denounces the factthat in its time circus games and theatrical performances were offered to Christ, as a token ofthanks for the triumphs obtained in the war against Rome 's enemies. The cause of this criticism is found in the theology of imperial victory: beginning with Constantine, the Christian God is concieved as the divine dispenser of victory for which several Christian symbols (for example, like the cross which overhung the sovereign scepter) were exhibited at the games played to celebrate the victories. To this element, we must add the christianization of the circus ritual, which we can observe as early as the fifth century. Upon his arrival on the stage, the emperor was used to bless the people, who then responded with acclamations that invoked the blessing of God on the king forever. Consequently all of these Christian elements present in the circus scandalized Salviano.

The prehistory of Palau and other parts of western Micronesia has recently become important to debates about the colonisation and pattern of cultural development in the west Pacific. The main reason for this has been the suggestion that the antiquity of human occupation there might be much earlier than has been thought (e.g. Masse 1990), ilnd well before the dispersal of Lapita culture from the Bismarck Archipelago to Samo,1, between 3300 and 2850 BP (Specht and Gosden 1998; Anderson and Clark 1999). Estimates for the settlement of the Marianas now start about -1800 years BP, with Palau occupied at 4500 BP and Yap probably before 3200 BP (Dodson <rnd Intoh 1999; Wickler 2001). These older than anticipated dates (e.g. Milsse 1990) are significant because they coincide approxunately with the spreild of a eolithic cultural complex in island South East Asia chilracterised by use of rice, pig and dog, manufacture of red-slipped or paddle-impressed cernmics, along with other distinctive portable artefacts that do not occur in pre-ceramic assemblc1ges of the region (Bellwood 2001 ). Direct evidence for the earliest settlement of the Marianas, Palau and Y<1p is, however, scarce, and has been largely inferred from the analysis of sediment cores which indicates anthropogenic activity eilrlier than the archaeological record In Palau these include the presence of charcoal particles, pollen from food plants like the giant swamp taro (Cyrtosperma clw111isso11is), and an increase in savannah plants at the expense of forest growth before 4000 BP (Athens and Ward 2001; Welch 2001). While the palaeoenv1ronmental results have furnished useful alternate colonisation chronologies there is a striking absence of early sites that allow us to identify either the origin and pattern of settlement m west Micronesia, or to investigate the colonisers' connection to early Austronesian movements in Island South East Asia and the Lapita dispersal in Near and Remote Oceania. This paper summarises recent investigations undertaken on the islands of Angaur and Ulong (Fig. l) aimed at recovering early cultural materials from Palau's sequence to clarify the archipelago's colonisation history. The earliest securely d,1ted and adequately reported cultural deposits from Palau date to rn. 2300 BP (Welch 2001), and several reasons for an absence of sites older than 2500 BP have been proposed. Why no early sites?


Most of the studies of the linkages between a city and its hinterland have hitherto been none other than the studies of the regional structure of the surrounding areas influenced by the functions of the city. But the auther thought that the economic and social linkages between a given city and its hinterland should naturally be reflected in the daily behaviors of the hinterland inhabitants going to the city; therefore, such linkages can be made clear by observing those behaviors. In this article, the author tries to clarify the linkages between the built-up areas of Takayama City and its hinterland in Hida region, Gifu Prefecture by analyzing those behaviors directed to the city in the daily life of the hinterland inhabitants. The survey was conducted in the following method; first, the author distributed questionnaires among the families of the first year pupils through junior high schools in Takayama City and surrounding five towns and seven villages; second, the author, considering the elementary school zones as minimum communities, divided the area into 57 sub-areas. Analyzing the informations collected from the questionnaires, the author could observe the following result: 1) When the inhabitants of the surrounding areas go to Takayama City, three kinds of behaviors are usually observed in this one action of going to the city; and the originally intended major behaviors such as attendings offices or schools are mostly accompanied by the secondary behaviors which the inhabitants already intend to do before they leave their home and the third entirely casual behaviors unintended beforehand. 2) Shopping is the most frequently observed behavior of this second and third kinds of behaviors. 3) The distribution of dwelling-places of the inhabitants who do shopping as the above-mentioned secondary behavior and the frequency of this kind of shopping in the city are related to the number of stores in each district. When there are few stores in a given district, the frequency of shopping as the secondary behavior corresponds to the distance from the district to the built-up areas of Takayama City or to the other concentrated districts of stores. The distribution of the dwelling-places of the inhabitants doing shopping as the third casual behaviors and its frequency have no relation to the number of stores in each district nor to the distance to the other concentrated districts of store; rather they are related to the traffic means from each district. 4) Attending offices, attending schools, attending hospitals and shopping are the four major behaviors through which the hinterland inhabitants are connected with the built-up areas of Takayama City. And the distribution and occurrence rate of the secondary behaviors and the third casual behaviors accompanying each of these four major behaviors are different according to what the major intended behavior is.


Based on the in-depth analysis of the structure and principle of Turbo Codes in LTE,the interleaving algorithm and distance property of QPP interleaver is derived detailedly.According to the property of maximum contention-free interleaving for QPP interleaver,a new parallel decoding scheme is proposed.The illegibility of initial boundary is eliminated by way of inserting tail bits periodically.The system model is established combining linear fitting Log-MAP decoding algorithm.Various factors that affect the error correction performance are simulated.Simulation results show that:combination of the proposed parallel decoding scheme and linear fitting Log-MAP decoding algorithm in LTE can reduce the decoding delay while ensuring the decoding performance.The scheme not only satisfies the requirements of the low signal to noise ratio,but also is propitious to hardware implementation.


– A compact frequency reconfigurable U slot circular microstrip patch antenna is proposed for LTE, WLAN and WIMAX applications. PIN diodes are appropriately positioned to alter the electrical length of U slot arm to achieve the frequency selectivity. The proposed antenna is radiated for 4.3-5.1 GHz LTE band, 5.5-5.85GHz WLAN band and 3.5 GHz WIMAX band. FR-4 substrate with dielectric constant εr=4.4 and thickness h=1.6mm parameters are employed for the proposed design. The overall dimension of the antenna is 33x 20mm^2 including ground plane. A good impedance match (return loss ≤ -10 dB) for all the bands is achieved. The Ansoft HFSS 12 is used to model and simulate the proposed antenna.


Liquid-phase benzene hydrogenation to cyclohexane was studied over Pd/γ-Al_2O_3 catalyst in a regime free of internal and external diffusion limitations. The effects of reaction temperature, hydrogen pressure and reactant concentration on the reaction rate were obtained experimentally between 393 K and 453 K and over a hydrogen pressure range from 1.1 MPa to 3.8 MPa. The result shows that the reaction rate is zero-order in benzene concentration and first-order with respect to hydrogen pressure and the activation energy is 43.88 kJ/mol. The kinetic model was further verified by the experimental data, which were obtained under lower reactant concentration.


This video features a scaled prototype of RWal (Reactive Wall) that was built based upon the floor plan of Hilton San Francisco Union Sq. Continental Ballroom. The RWal is a continuum surface intelligent system that is commissioned in a conference area. It can sense occupancy in different session areas and change its shape dynamically so that it provides more space for a session that is crowded at the expense of reducing the room space for a session that is sparsely populated. Temperature sensors are used to monitor occupancy and the walls are manipulated by tendons driven by servo motors and controlled by an Arduino ATMega328 microcontroller. The wall is actuated (actively and passively) at different points and is designed in such a way that it encloses a constant volume space. The key idea is to manage the available floor area to prevent congestion. This will be a practical option in any conference where there are typically boring as well as interesting speakers and an unavoidable movement of attendees from one session to another.


Increased removal of biomass from forested ecosystems for use as an alternative source of energy is an option in several countries. E.g., it is planned to double the use of bioenergy from all sources until 2020 in Norway. A large fraction of this increase is coming from forest resources, e.g. by removing harvest residues like branches and tops. This removal will reduce the supply of nutrients and organic matter to the forest soil, and may in the longer term increase the risk for future nutrient imbalance, soil erosion on steep slopes, reduced forest production, and changes in biodiversity and ground vegetation species composition. However, field experiments so far have found contrasting results in this respect. Soil effects of increased biomass removal will be closely related to soil organic matter (SOM) dynamics, litter quality, and turnover rates. Harvest intensity may affect the decomposition of existing SOM as well as the build-up of new SOM from litter and forest residues, by changing factors like soil temperature and moisture as well as amount and type of litter input. Changes in input of litter with different nutrient concentrations and decomposition patterns along with changes in SOM decomposition will affect the total storage of carbon, nitrogen and other vital nutrients in the soil.


IN THE ENGLISH PRONUNCIATION of a number of geographical and personal names, when a weakly stressed syllable containing la I or /il comes under greater stress, whether for reasons of rhythmical alternation, recession of primary stress, or whatever, the quality of the vowel often changes in the newly stressed syllable.2 It has been known, of course, at least since the time Verner's Law was formulated that shifts in stress cause qualitative changes in the vowels involved, and every student of the history of the language has noticed the vowel gradation in a series like photograph /ow, a, re/, photographer la, 0, a/, photographic low, a, re/. It seems worthwhile to continue the study of this phenomenon, however, in order to gain a better understanding of the extent to which proper names are affected, and in the process to determine further the extent to which by examining the nature of the syllables involved, whether in proper names or not, we can generalize about the quality of the newly stressed vowel.3 Also by noting the extent to which words that are not names are subject to the same sort of vowel gradation, we can have a better idea about how "regular" this particular kind of sound change is in proper names.4


Knowledge of the use of plants, particularly native plants, in New Zealand for ground bioengineering and erosion and sediment control is outlined in a brief review of unpublished and published information. In general, our level of knowledge about what makes any plant useful for these purposes is poor, particularly in regard to performance or effectiveness of individual plants or plant systems. Much of the knowledge is experiential rather than tacit, and what has been recorded is often in the grey literature. Limited data exist for some New Zealand native plants, but most are for a few species, of a limited age range and sample number, and have only been collected in the last 10 years or so. This paucity of quantitative data is set in the context of a resurgent interest in bringing more native plants into New Zealand's managed or cultural landscapes coupled with a desire to remove exotic plants such as willows, which are currently performing many functional ground bioengineering roles. Much of this recent focus has been to enhance indigenous biodiversity and to improve water quality in streams. However, opportunities to redress our shortfall in knowledge are beginning to appear in association with development industries such as roading, mining, and construction where the use of plant materials to perform functional roles is only now being recognised.


This paper describes the analytical development of a model representing a hingeless helicopter rotor equipped with trailing-edge flaps. The objective of the model is to provide an analytical tool that can be used to investigate major trends when specific physical parameters are changed, as well as to serve for the definition of parametric uncertainties in robustness analysis. The derivation follows a Lagrangian approach and includes the blade lagging, flapping, and torsional degrees of freedom. The aerodynamics of the blades is modeled using the thin-airfoil lifting-line theory and accounts for changes induced by the trailing-edge flaps on aerodynamic coefficients. The model is suited to cope with low-frequency dynamics such as lead–lag dynamics or rotor-blade tracking and balancing. It is validated against a Finite Element Method numerical model of the EC145 active hingeless rotor and against flight-test data provided by an EC145 demonstrator, both featuring trailing-edge flaps. The model shows great pot...

We prove that the group defined by a cubical presentation 〈X | Y1, . . . , Ys〉 satisfying sufficient non-metric cubical small cancellation conditions is (relatively) hyperbolic if the complex X is (relatively) hyperbolic. This can be thought of as a generalization of the fact that classical C(7)-small cancellation groups are hyperbolic.

McKinsey{Tarski (1944), Shehtman (1999), and Lucero-Bryan (2011) proved completeness theorems for modal logics with modalities 2, 2 and 8, and [@] and 8, respectively, with topological semantics over the real numbers. We give short proofs of these results using lexicographic sums of linear orders.


We tested the impulse breakdown voltage of Al2O3 "nano-modified" propylene carbonate between different electrode materials. At any given concentration, the breakdown voltage was highest with stainless steel electrodes, followed by copper, and then aluminum. The space charge and electric field distributions were measured too. Results show that less space charge was injected by the electrodes, and the electric field was less distorted, than in pure propylene carbonate. However, the hoped-for reduction of the influence of the electrodes did not take place. Substantial differences in the space charge density and electric field distortion remained between the different electrode materials.


Developments in the foundations of mathematics, in particular, Gödel's undecidability proof are brought to bear on group therapy, social therapy, and human emotionality. The pre-Gödelian notion that the group is nothing more than the sum total of its individual members fosters the positivistic position that what is happening in a group is decidable or determinable. In contrast, it is argued that groups, like formalized mathematics, are undecidable. This point and its therapeutic implications are expanded upon through a discussion of the group practice of social therapy. Examples of social therapy group activity are provided to illustrate the methodological and philosophical character of the therapy, and in particular, the importance of creative unresolvability to emotional growth.


The education software production had a major boost in recent years because of increasing access to the internet and the possibility of collaboration of thousands of people around the world. Several initiatives opens up a wide array of options for learning on the web, with massive open online courses (MOOCs), learning objects repositories, evaluation and content publication. Specifically in the evaluation field, there is the AvalWeb® application, a software that allows management of questions, creating an evaluation that establishes dynamic rules that can make a test measure the student's knowledge more accurately. This paper describes the technology and the design of a new version of the AvalWeb® system using new technologies for the web that provides responsive pages and ease of use of modern web Apps.


antiphlogistic drugs were investigated. The basic components in them were sodium salts of diclophenac and they difiered from one another with the chemical composition of other components. It was found that in all of the investigated spectra there occurred a component which testifled to the formation of positronium. The difierences in the values of ortho-Ps component lifetimes and their intensity can be attributed to the presence of ingredients modifying the efiects of the drug.


The Ediacaran age (ca. 570 Ma) Shuram excursion, a ca. 12h depletion in δCcarb, may record a dramatic oxidation of marine sediments associated with a reorganization of Earth's carbon cycle closely preceding the rise of large metazoans. However, several geochemical indicators suggest it may instead record secondary processes affecting the sediments such as post-depositional alteration. The stable isotopic composition of iron incorporated within carbonates (δFecarb) reveals an anomalous 56Fe-depletion (down to −1.05h) in strata containing the Shuram excursion, while the underlying and overlying strata have crustal δFecarb values. These depleted δ Fecarb data during the Shuram excursion reflect incomplete reduction of iron oxides, limited by low ambient organic carbon contents. This elevated pulse of sedimentary iron oxides would consume the majority of the limited pool of organic carbon and therefore would give rise to very low net organic carbon burial during a time of enhanced detrital delivery of oxidized iron to the sediments. These results imply a syndepositional origin for the Shuram excursion, which represents a shift in the redox composition of Earth's sedimentary shell toward more oxidizing conditions, perhaps removing a long-lived buffer on atmospheric

I WOULD LIKE TO THANK BRUCE SMITH for the honor of participating on this panel with such distinguished experts on central banking and payments. Moreover, Bruce should be commended for putting together an outstanding conference on what is probably the most important issue that the Federal Reserve System (at least the Federal Reserve Banks) will need to grapple with early in the twentyfirst century. To understand the role a central bank should play in the economy one needs to think carefully about what forms of market failure require this form of government intervention in the market. The existence of financial intermediaries tells us that the perfect capital market assumptions that underpin the M&M irrelevance results do not hold. For policymakers, the question is not whether financial markets (money, capital, and payments markets) are frictionless. Rather, the question is, do the private-sector institutions that arise to mitigate (or arbitrage away) market frictions serve to complete the markets? If not, then public intervention in markets may be required. In this case, we are interested in the role a central bank may play in completing markets. The papers presented in this volume provide some answers as to the central bank' s role in money and payments. I doubt there is much controversy in asserting that central banks have a role in establishing the unit of account (although in small open economies a currency board may serve this function) and in serving as the liquidity backstop for financial markets. In turn, these two roles for the central bank may require that payments be ultimately settled in central bank liabilities (base money) and hence, be settled on the books of the central bank. What is not clear is the need for the central bank to provide the medium of exchange in the form of fiat money. A common theme across these papers is that properly structured private provision of money, or banknotes, is not only feasible, it may be desirable. The papers by Williamson (1999) and Cavalcanti and Wallace (1999) show that inside money (banknotes) results in superior outcomes with respect to economic ef-


Robotic surgical subtask automation has the potential to reduce the per-patient workload of human surgeons. There are a variety of surgical subtasks that require geometric information of subsurface anatomy, such as the location of tumors, which necessitates accurate and efficient surgical sensing. In this work, we propose an automated sensing method that maps 3D subsurface anatomy to provide such geometric knowledge. We model the anatomy via a Bayesian Hilbert map-based probabilistic 3D occupancy map. Using the 3D occupancy map, we plan sensing paths on the surface of the anatomy via a graph search algorithm, $A^*$ search, with a cost function that enables the trajectories generated to balance between exploration of unsensed regions and refining the existing probabilistic understanding. We demonstrate the performance of our proposed method by comparing it against 3 different methods in several anatomical environments including a real-life CT scan dataset. The experimental results show that our method efficiently detects relevant subsurface anatomy with shorter trajectories than the comparison methods, and the resulting occupancy map achieves high accuracy.

In this developing stage of our nation, spreading of obscene images has become a major issue among the teenagers. There are certain techniques to avoid online obscene images and videos. There is a major possibility to transfer such images via external devices. This paper says about how to avoid the transfer of obscene images via external devices. When an external device is connected to the system and if the proposed method detects obscene image the system will automatically rejects the external device. The detection of obscene images is done in three steps which includes skin color detection, face detection and a fine detection using Convolutional Neural Network (CNN). Our proposed method expects 97.04% of recognition accuracy.


A multi-band low-pass sigma-delta ($\Sigma \Delta$) modulator with cascaded integrators and voltage-controlled oscillator with divider are presented for phase locked loop controller. The proposed prototype of phase locked loop was implemented in tsmc 0.18 $\mu$m CMOS process. Another feature is that only one set loop filter is designed to promote multi-band by auto-switching capacitors with quantum algorithm from phase frequency detector to achieve a multi-band solution. Experimental have achieved the SNDR of 42/33 dB over 1/2 MHz, respectively for low power multi-band phase locked loop sensor control applications.

The resonance light scattering(RLS) spectra of the interaction Quinine dihydrochloride (Quinine)with perfluorooctane sulfonate (PFOS) was investigated. A RLS method for the determination of PFOS has been established. In pH 2.87 Britton-Robinson (BR) buffer solution, perfluorooctane sulfonate (PFOS) anions can react with the protonated Quinine by electrostatic forces and hydrophobic interactions to form 2:1 ion-association complexes and resulting in greatly enhanced resonance light scattering signals characterized by a peak at 283 nm, and the RLS intensity was proportional to the concentration of PFOS in the range of 0.10 ~ 5.00 μmol/L. The limit of detection is 9.88 nmol/L. In this paper, the optimum reaction conditions and the interference of foreign substances of the system were investigated. The absorption and fluorescence spectra of the system as well as the reaction mechanism were also discussed. This RLS method has been applied to the determination of PFOS in environmental samples and human serum samples with RSD ≤ 4.2%.


Unsupervised learning can address the general limitation of supervised learning that sense-tagged text is not available for most domains and is expensive to create. However, the existing unsupervised learning probabilistic models are computationally expensive and convergence slowly because of large numbers and random initialization of model parameters. This paper reduces the noise jamming and the dimensionality of the models by using proposed feature selection and initial parameter estimation. Experimental result shows the accuracy and efficiency of the proposed probabilistic model are obviously improved.


An electronic portfolio is an ideal tool for meeting the needs of established and emerging pedagogy and approaches to learning, and many educators see E-portfolios as vital to learning, teaching and assessment. The participants in this quasi-experimental study were forty-five undergraduate students who were studying the English IV course at Suranaree University of Technology, Thailand. The purposes of this study were to investigate the effects of a Weblog-based E-portfolio on the English writing skills of Thai EFL undergraduate students before and after learning; and to find out their opinions of learning through a Weblog-based E-portfolio to improve their English writing skills. The participants writing skills were assessed by means of a pre-test, and a post-test was administered after they had studied writing using the Weblog-based E-portfolio. The participants expressed their opinions by means of reflective journals and a questionnaire regarding improvements in their writing skills through the use of the Weblog-based E-portfolio. The results of the study showed that the Weblog-based E-portfolio was effective based on the 80/80 standard criterion; and the post-test results of the participants' writing skills were significantly higher than the pre-test results. In addition, the results obtained from the questionnaire and reflective journals showed that the participants had positive opinions towards learning through the Weblog-based E-portfolio.


The purpose of this study was to examine the long-term effects of static stretch of the plantar-flexor on eccentric and concentric plantarflexion torque and ankle dorsiflexion range of motion (ROM) in healthy subjects. Fifty healthy male volunteers, with no previous history of trauma to the calf that required surgery, absence of knee flexion contracture and no history of neurologic dysfunction or disease, systemic disease affecting the lower extremities. The participants randomly divided in two equal groups. The experimental group was instructed to perform the static stretching exercise 30-second (5 repetitions) twice daily. The stretching sessions carried out at least 5 days a week for 6 weeks. The control group did not stretch plantar-flexor. All subjects measured the dorsiflexion ROM, also measured the eccentric and concentric torque of plantar-flexors at angular velocities 30 and 120°/sec pre and post stretching. Analysis of variance proved significant (P<0.05) increase in plantar-flexor eccentric and concentric torque and an increase in dorsiflexion ROM at both angular velocities. It was concluded that static stretch program of plantar-flexors is effective in increasing the concentric and eccentric plantarflexion torque at angular velocities 30 and 120°/sec. Also, it induced increases in plantar- flexors flexibility. 8 consecutive weeks, with a total of 86 minutes 40 Many authors have studied the acute effect of a seconds in each session. The study proved that there was stretching routine on strength performance, but the a significant increase in flexibility (up to 6.3%), in knee results are often controversial. Various studies indicated flexor and extensor muscle eccentric peak torque (18.2 and that stretching exercises preceding the main strength 23.0%, respectively), knee flexor concentric peak torque activity significantly decrease the performance (2-12). (9.4%) and knee flexor isometric peak torque (11.3%). In These studies used stretching exercise of lower addition, PNF method recorded higher improvement rates extremities and found a decrease in strength ranged from than the static stretching method in the range of motion 4.5 to 28%, irrespective to the testing mode (i.e. isometric, and in the muscular strength variables of both stages, isotonic or isokinetic) (1).


Objective: Ventilation tube insertion is the primary surgical intervention in persistent otitis media with effusion. Around 7% of ventilation tubes require elective removal. The objective is to discover the tympanic membrane healing rate after ventilation tube removal and identify measures that improve this. Method: Retrospective case note review performed for patients who had elective ventilation tube removed over an 8-year period. Information gathered included if any concomitant procedure was performed to repair the tympanic membrane and final outcome of the tympanic membrane status. Results: A total of 113 cases were included in this study. The average age at grommet insertion and removal was 5.8 years old and 8.3 years old, respectively. After ventilation tube removal the perforation edges were freshened in all cases. The majority of patients (84.1%) subsequently had an intact tympanic membrane. Additional procedures were performed on 19 ears, 6 with insertion of overlay absorbable material and 14 with a fat plug. Closure rate in these patients was 100%. Shah and Sheperd grommets had a significantly lower residual tympanic membrane perforation rate compared to T-Tube and Titanium grommets. Conclusion: Tympanic membrane closure rate after ventilation tube removal was 84.1%. Additional procedures, ie, overlaying of absorbable material, appear to improve the closure rate. We therefore advocate the technique. In selected cases such as T-tube removal a concurrent fat plug myringoplasty may be appropriate.

While a number of companies have embraced Twitter, many CEOs don't leverage the power of Twitter to the fullest extent. As of September 2014, only 42 Fortune 500 CEOs had Twitter accounts. Of those, only about 70% were truly active and tweeting in a meaningful way. One high-profile Twitter user is Elon Musk, CEO of Tesla Motors Inc. and SpaceX. Musk typically tweets numerous times a month, and his tweets sometimes contain new and exciting information. Twitter, one of the worlds leading social media platforms,2 has more than 300 million active users. In contrast to Facebook, which skews heavily toward personal communication, Twitter is used more actively for business. As a result, brand managers, customer service agents, and other businesspeople became early adopters so that they could stay abreast of the streams of information they cared about. Rather than waiting for impressions to be driven by the media or individuals with ulterior motives, CEOs can use tweeting to help shape their public image and that of their companies. This article describes the opportunities for CEOs.


This chapter explores the work of Pearl Gibbs throughout her exemplary career as an activist and tireless campaigner for Aboriginal rights and democracy in Australia from the 1930s until her death in 1983. Pearl's activism on a national level is well documented in the historiography of Aboriginal politics and campaigns for Aboriginal rights, because of her role as a member of the 1930s Aboriginal campaigns for rights and as a member of the Aborigines Progressive Association and their 'Day of Mourning' campaign for Aboriginal citizenship in 1938,3 as well as her later roles within women's organisations and working with other women campaigners like Faith Bandler, Joan Strack and Jessie Street.4 Pearl Gibbs is, however, also remembered in other contexts, and for other reasons, and she is particularly fondly loved and respected by the Aboriginal community in Dubbo, NSW, where she lived for many years, both as a young woman and later in her life.


With the purpose of improving an analytical method for the determination of selected phenolic compounds in quince jams, a comparative study of recoveries by two different non-polar sorbents, Isolute C18 non end-capped (NEC) and Isolute C18 end-capped (EC), was performed. Significant differences in the recovery percentages were found. The results suggest that Isolute C18 (NEC) is the most suitable for the recovery of the selected phenolics from quince jams, when 1% of methanol was added to the samples. The reversed-phase High-Performance Liquid Chromatography/Diode Array Detector (HPLC/DAD) procedure is rapid, sensitive, reproducible, and accurate. The improved sample preparation was simple, involving only a C18 Solid-Phase Extraction (SPE) purification step. The detection limit values for phenolic compounds were between 0.1 and 1.6 μg mL−1 and the method was precise. As a general rule, the recovery values were high, except for arbutin. This technique can also be useful in the evaluation of commercial quince jams genuineness.

Abstract. The HL‐A histocompatibility locus is closely linked to that for the glycinerich β‐glycoprotein polymorphism. No recombinants were seen among 44 children from 12 informative families.


Depth maps are frequently analyzed as if, to an adequate approximation, the errors are normally, identically, and independently distributed. This noise model does not consider at least two types of anomalies encountered in sampling: A few large deviations in the data, often thought of as outliers; and a uniformly distributed error component arising from rounding and quantization. The theory of robust statistics formally addresses these problems and is efficiently used in a robust sequential estimator (RSE) of our own design. The specific implementation was based on a t-distribution error model, and this work extends this concept to several well known M-estimators. We evaluate the performance of these estimators under different noise conditions and highlight the effects of tuning constants and the necessity of simultaneous scale and parameter estimation.


An experimental approach is described for obtaining highly enriched residual gas under
IR multiphoton dissociation (MPD) of molecules in one cycle of irradiation. The
approach is based on utilization of a pulsed molecular flow of small length (Δxfl≤1cm).
The use of a short flow length leads to high values of the dissociation yield of molecules
(β≃1) in the whole volume of the flow. Owing to this, high enrichment of the residual
gas is achieved in one cycle of irradiation. The isotopically-selective dissociation of CF3I


Shape memory alloys have been widely proposed as actuators, in fields such as robotics, biomimetics and microsystems: in particular spring actuators are the most widely used, due to their simplicity of fabrication. The aim of this paper is to provide a general model and the techniques for fabricating SMA spring actuators. All the steps of the design process are described: a mechanical model to optimize the mechanical characteristic for a given requirement of force and available space, and a thermal model for the estimation of the electrical power needed for activation. The parameters of both models are obtained by experimental measurements, which are described in the paper. The models are then validated on springs manufactured manually, showing also the fabrication process. The design method is valid for the dimensioning of SMA springs, independently from the external ambient conditions. The influence on the actuator bandwidth was investigated for different working environments, providing numerical indications for the utilization in underwater applications. The spring characteristics can be calculated by the mechanical model with an accuracy of 5%. The thermal model allows one to calculate the current needed for activation under different ambient conditions, in order to guarantee activation in the specific loading conditions. Moreover, two solutions were found to reduce the power consumption by more than 40% without a dramatic reduction of bandwidth.


This paper proposes a new algorithm that generates smooth and realistic transition views from one viewpoint to another view point on the panorama based navigation system. The proposed algorithm is composed with two steps. One is prewarping that aligns the viewing direction in two panorama image, the other is bidirectional disparity morphing (BDM) that generates the intermediate scene from the aligned panorama images. For the prewarping, first of all, we compute the phase correlation between two images in order to get the information such as the displacement, rotation, and scale. Then we align the original images using these information. As soon as finishing the prewarping, we compute the block based disparity vectors (DVs) and smooth them using the two occluding patterns. As we apply these DVs to the BDM, we can get the elaborate intermediate scenes. We make an experiment on the proposed algorithm with real panoramic images and we can get the satisfactory results.


OBJECTIVE: To test short-term and long-term elastomeric infusion pumps for applicability in hospital practice and for ambulant patients at home. DESIGN AND METHODS: Four short-term elastomeric infusion pumps (Accufuser C1000M, Easypump ST 100-1, Infusor Intermate SV-100, Surefuser Plus 100 ml) and four long-term pumps (Accufuser C0100L, Easypump LT 270-24, Infusor Folfusor LV-10, Surefuser Plus 18102-01) were included in the study. Each was exploratively tested for accuracy and uniformity of the flow rate and sensitivity to external factors (temperature, fluid viscosity, height difference between pump and patient connection, filling degree), residual volume, evaporation upon storage, warming-up time and sterility. RESULTS: Flow rate of short-term pumps was less constant than of long-term pumps and displayed more deviations. For most pumps tested, the flow rate decreased in time. Flow rate increased at temperatures higher than the calibration temperature and decreased at lower temperatures. Higher fluid viscosity reduced flow rate. Differences in height between pump and patient connection up to 10 cm slightly influenced flow rate. Filling degree less than the nominal value reduced flow rate. Evaporation upon storage in the refrigerator was limited. Warming up from refrigerator to room temperature maximally required six hours. Sterility was maintained upon four weeks storage at 35°C. CONCLUSION: Flow rate of elastomeric infusion pumps was not constant and was significantly influenced by external factors. There was little difference in outcome between the pumps tested. Other factors (beyond the scope of this study), such as ease to prepare, patient-friendliness and price are also important determinants for making a choice. Principally because of the limited accuracy of the flow rate, we consider elastomeric infusion pumps less suitable for administration of cytostatic agents and pain treatment than for antibiotics.


Statistics show that two thirds of American Indians and Alaska Natives (AIs/ANs) live outside of tribal areas, and 50% of those individuals who seek counseling services will not use tribal resources. There is a strong likelihood that counselors will have the opportunity to provide services to AI/AN clients. The review of the academic literature focused on counseling services for AIs/ANs revealed three primary themes. These themes include issues regarding cultural competency, awareness of different levels of acculturation, and the appropriateness of utilizing Eurocentric counseling theories with AIs/ANs. Perhaps more importantly, these themes often emerge within the context of family and tribal unity. These issues, as well as some general guidelines for counseling indigenous families, are addressed within this article.


The automotive electronic throttle (AET) control system has been widely applied in modern automotive engines, and accurate control of AET can improve engine performance as well as reduce pollution emissions. However, the noise in the sensor circuit and the variation in automotive driving conditions seriously affect the control performance of the AET system, making controller designing challenging. This paper proposes a self-tuning backstepping control with a Kalman-like filter (SBCKLF) strategy. First, the noise affecting the position sensor measurement is verified to be non-Gaussian by acquiring and processing the noise signal. To eliminate its influence on control precision, a Kalman-like filter is introduced to estimate the real position of the valve. Then, a self-tuning backstepping controller is designed to automatically adapt to the variation in vehicle driving conditions. A self-tuning algorithm based on fuzzy control is used to tune the parameters of the backstepping controller online, so as to optimize the controller performance. Finally, an experimental platform based on dSPACE for the AET control system is built to perform the controller comprehensive test in a real-time environment. Experimental results and performance analysis demonstrate the effectiveness of the proposed SBCKLF strategy. Compared to the best results of other methods, the proposed method reduces the maximum and root mean square tracking errors by 21.65% and the average error by 12.89%. The steady-state and tracking error bounds are controlled to 0.9° and 2.3°, respectively. It also shows that the SBCKLF strategy has the strongest robustness as well as the best response speed.


This paper reports the simulation, fabrication and characterization of a 3-DOF piezoelectric micro vibratory stage design with large X/Y-tilting and Z-translational motion capabilities. The vibratory stage utilizes four piezoelectric crab-leg suspensions formed of bulk-PZT/Si unimorph beams in a L-shaped layout. FEA simulations are utilized to optimize the PZT/Si thickness ratio and characterize the 3-DOF actuation modes and off-axis coupling. A 3×3-mm2 sized stage is fabricated via a process that includes bonding and thinning of bulk-PZT substrates on pre-patterned silicon features and micro-patterning of thick PZT films via wet etching. At ±25 V static excitation, X-tilting and Y-tilting angle ranges are measured as >2.3°, and Z-translational displacement is 42 μm. At resonance, the tilting angle range is 12.2° (~1.77 kHz), and the vertical displacement range is 387 μm (0.93 kHz). The device consumes only 100 μW and <;450 μW during static and resonant operation, respectively.


Neural networks with word embedding have recently used for document classification. Researchers concentrate on designing new architecture or optimizing model parameters to increase performance. However, most recent studies have overlooked text preprocessing and word embedding, in that the description of text preprocessing used is insufficient, and a certain pretrained word embedding model is mostly used without any plausible reasons. Our paper shows that finding a suitable combination of text preprocessing and word embedding can be one of the important factors required to enhance the performance. We conducted experiments on AG's News dataset to compare those possible combinations, and zero/random padding, and presence or absence of fine-tuning. We used pretrained word embedding models such as skip-gram, GloVe, and fastText. For diversity, we also use an average of multiple pretrained embeddings (Average), randomly initialized embedding (Random), task data-trained skip-gram (AGNews-Skip). In addition, we used three advanced neural 문서 분류를 위한 신경망 모델에 적합한 텍스트 전처리와 워드 임베딩의 조합 691 networks for the sake of generality. Experimental results based on OOV (Out Of Vocabulary) word statistics suggest the necessity of those comparisons and a suitable combination of text preprocessing and word embedding.


It is shown that an unstable bending wave may be excited in an elastically supported beam by a travelling inertia load. Since the occurrence of this dynamic instability reduces the axial buckling load of the beam, the result is relevant to present studies of the temperature buckling of continuous welded railway track.


s of papers presented at the Mammalian Genetics Group meeting held in the Linnean Society Rooms, Piccadilly, London, on 25 and 26 November 1986 A Robertsonian translocation involving the Z-chromosome of the mouse I.-D. ADLER, R. SCHMO LLER*, B. NETHER* AND R. JOHANNISSONf * Institut fur Sdugetiergenetik, GSF, D-8042 Neuherberg, f Inslitut fur Pathologie, Medizinische Universitat, D-2400 Liibeck, F.R.G. A Robertsonian translocation between the X and chromosome 2 was recognized in a son of a female carrying the reciprocal translocation T(5; 13). The original Rb(X. 2)Ymale was mated to (101/E1 x C3H/E1)FX females with a mean litter size of 6-5 + 2-7 (four litters). The line was made homozygous. Two distinct centromeric heterochromatin blocks are present in C-banded trivalents at meiosis and in the metacentric chromosome in C-banded mitotic cells. The inactivation of the X.2 element was tested with a (non-agouti) as a marker on chromosome 2 and Ta (tabby) as a marker on the A'-chromosome. The results indicate that there is no influence of the Robertsonian translocation on random A-inactivation and that the inactivation does not spread beyond the centromere to a. The non-disjunction of sex-chromosomes in Rb(X. 2)Y males studied in spermatocytes at the second meiotic division showed 3% cells with 18,A\2, Fand 4% cells with 19,0. Tail-tip preparations of newborns performed for matings to obtain a homozygous Rb(Z. 2)-stock revealed 4% double A'-males but no triple-A' females among the progeny. The (X.2)XY and (X.2)(X.2)Y males were sterile, with spermatogenic breakdown prior to pachytene. The synaptonemal complex in Rb(Z. 2) Y males viewed in the electron microscope showed complete pairing between X. 2 and the acrocentric chromosome 2 only in one out of 52 cells. Association between Y and the unpaired segment of 2 formed a ring in 11 % of the cells, 80% of these were in late pachytene. The Rb(A\2) is the first available Robertsonian translocation involving the A'-chromosome and will serve as a valuable tool to study a number of biological problems. EUROGEN European Central Mouse Facility R. G. M. TEN BERG AND J. H. M. HILGERS The Netherlands Cancer Institute, Plesmanlaan 121 1066 CX Amsterdam The Netherlands To the Commission of the European Communities a proposal has been presented for a concerted action at the European level in Life Science, more particularly in the field of murine genetics of cancer. Such a concerted action programme can include a Central Facility. In this instance a central facility (or facilities) will be directed to mouse genetics related to cancer research. This action will fit in the Second Strategic Framework Programme for the period 1987/91 of the European Community Biotechnology Medical and Health Research Programme. The European Commission suggests that new action has to be taken on cancer. This action will be directed to improve services, infrastructures and communication in the Community. This European Indirect Action Programme has been broadened and will also include the Genetics Division of the Medical Research Council Radiobiology Unit (Dr M. F. Lyon/Harwell) and the Unite de Genetique des Mammiferes d'Institut Pasteur (Dr J. L. Guenet/Paris). These three institutes house and use large numbers of genetically defined strains of mice. Amsterdam, Harwell and Paris provide breeding stocks to many other workers in the EC and other countries and collaborate with many other laboratories. The Amsterdam, Harwell and Paris mouse genetics facilities therefore constitute a valuable resource for the EEC. There is clearly a ' supra-national' element in that the collaboration of the three laboratories in holding complementary ranges of stocks provides for the EEC a greater availability of strains than any one country could hold. It is proposed that these three institutes should jointly form an organization known as EUROGEN with the following aims: (1) Maintenance of a wider range of wild mice stocks, mouse inbred strains, congenic strains, recombinantinbred strains, mutants, polymorphisms, transgenics and chromosome anomalies. The stocks maintained in the


Central to Nozick s Anarchy, State and Utopia is a defense of the legitimacy of the minimal state s use of coercion against anarchist objections. Individuals acting within their natural rights can establish the state without committing wrongdoing against those who disagree. Nozick attempts to show that even with a natural executive right, individuals need not actually consent to incur political obligations. Nozick s argument relies on an account of compensation to remedy the infringement of the non-consenters procedural rights. Compensation, however, cannot remedy the infringement, for either it is superfluous to Nozick s account of procedural rights, or it is made to play a role inconsistent with Nozick s liberal voluntarist commitments. Nevertheless, Nozick s account of procedural rights contains clues for how to solve the problem. Since procedural rights are incompatible with a natural executive right, Nozickeans can argue that only the state can enforce individuals rights without wronging anyone, thus refuting the anarchist.


A layout survey is required to improve the production flow of a steel company. A reliable layout provides improvements in productivity and savings because it states a better distribution for machinery, appliances and human resources. In this paper the layout of a steel company is analyzed. It is found that the production flow does not match with the physical positioning of the machinery that designs the production line of the company. Following this analysis, a reformulation of the layout is proposed to aim the reduction of processing appliance transportation time, leading an improvement in the capacity of production and a reduction in setups times. Pursuing the implementation of the new layout, a search was developed to compare the outputs before and after the redefinition of the layout. The result highlights improvements as shortening processing appliance transportation time, broadening production programming performance and lessening setup times in the lines.


Verrucae (synonym: warts) are one of the most common viral infections of humans in which the most frequently used modalities of treatment involve destruction of the affected area, which does not prevent recurrences and often results in scarring. In the present study oral zinc sulphate, an immunomodulator was evaluated as a treatment modality for warts. A placebo-controlled, single-blinded study was conducted on one hundred OPD patients with various types of verrucae. Fifty patients were put on oral zinc sulphate at dose of 5mg/kg for six weeks, while an equal number of patients received placebo for the same duration. In the patients who received oral zinc sulphate, 60.97% showed complete response at the end of six weeks in comparison to 6.45% partial response in the placebo group. The resolution of the lesions occurred with restoration of normal epidermal texture with transient alteration in pigmentation.

Berries of three Romanian Lonicera caerulea cultivars 'Cera', 'Kami', and 'Loni', grown at the Research Institute for Fruit Growing, Pitesti, Romania, were analyzed between 2020 and 2022 in terms of chemical composition. The study aimed to determine the concentrations of some compounds with antioxidant activity, highlight the most valuable cultivar, encourage the consumption of honeysuckle berries, and indirectly stimulate growers' interest in this little-known species in Romania. Some phenolic compounds—lycopene, β-carotene, and vitamin C—were quantified. As a result of the study, the 'Loni' cultivar's high total phenolic content, flavonoids, anthocyanins, vitamin C, lycopene, chlorogenic and neochlorogenic acids, catechin, and rutin are to be noted. 'Cera' cultivar had the highest cryptochlorogenic acid content, and 'Kami' summarized the highest carotenoid level. These characteristics indicated that the three honeysuckle cultivars' berries could have multiple uses, from fresh consumption, as part of a diet focused on maintaining human health, to being used as raw materials in the para-pharmaceutical industry, to obtain food supplements. The novelty characteristics and the nutritional value of its berries highlighted by this study have indicated that honeysuckle can become a crop of interest and profitability.


Spectra of six Wolf-Rayet stars in the Large Magel- lanic Cloud (LMC) of the subtype WC4, the dominant WC spectral type in the LMC, are taken with the Faint Object Spec- trograph (FOS) on board the Hubble Space Telescope (HST). They are analyzed by means of non-LTE models for spherically expanding atmospheres computed using standard assumptions. Complex model atoms of helium, carbon and oxygen are taken into account. We nd stellar luminosities in the range from 10 5:1 L to 10 5:6 L, and mass loss rates of approximately 10 4 M yr 1 . The stellar temperature T?, dened as the effective tempera- ture related to the stellar core radius, is of the order of 100kK. The atmospheric compositions show carbon mass fractions of about 0.4, oxygen mass fractions in the range 0.1-0.3 and no indications of nitrogen. Stellarparametersobtainedthiswaybuildanempiricalbasis for the understanding of the late evolutionary phases of massive stars. The C/He and O/C abundance ratios are sensitive dis- criminates of stellar evolutionary models, since they depend, for example, on the adopted mass loss relation, the amount of overshooting, the 12 C(;) 16 O reaction rate, and the metallic- ity of the progenitor. We compare our results to evolutionary calculations and to a galactic sample of WC stars. The deduced abundances agree with some evolutionary calculations, but are in disagreement with others. The derived mass loss rates are found to be in gen- eralagreementwithcommon _ M-L-relations.Systematicdiffer- ences between the galactic and the LMC sample exist, possibly reflecting a dependence of WC mass loss on metallicity.


D die-stacked chips can alleviate the penalties imposed by long wires within micro- processor circuits. Many recent studies have attempted to partition each microprocessor structure across three dimensions to reduce their access times. In this paper, we implement each microprocessor structure on a single 2D die and leverage 3D to reduce the lengths of wires that communicate data between microprocessor structures within a single core. We begin with a criticality analysis of inter-structure wire delays and show that for most tra- ditional simple superscalar cores, 2D o orplans are already very ecien t at minimizing critical wire delays. For an aggressive wire-constrained clustered superscalar architecture, an exploration of the design space reveals that 3D can yield higher benet. However, this benet may be negated by the higher power density and temperature entailed by 3D in- tegration. Overall, we report a negative result and argue against leveraging 3D for higher ILP.


Those who were born the year that Mikhail Gorbachev became the leader of the Soviet Union will have their twenty-first birthday this year and either are in the labor force or will be graduating from a university in a year or two. This generation has experienced a world that is starkly different from that which their parents experienced, and it is the generation that will decide Russia's destiny in the coming decades. A glimpse of what this new generation is like is provided by M. Lisauskene in "A New Generation of Russian College Students." According to the data presented on a sample of students in the Irkutsk region, students are very ambitious and see higher education as the way to make their way in the world. After a severe decline in the early 1990s in the proportion of young people who wanted to go to a university, the situation has been reversed and it is now a major goal of young people. Most of them are committed to working in their specialty, are looking for a career in business (about one in five intends to start his own), and they expect to have to rely on their resourcefulness to get ahead. They also want to preserve their independence, and are counting on enjoying the good things in life. At the same time, "one-third say that 'there are no honest and dishonest ways of making money.' One out of every five would like to 'make a lot of easy money and right away.'" Of special interest is that there are differences within this generation, resulting from having grown up at different historical eras. As Lisauskene puts it, an "analysis of the structure of the 'next generation' shows that there have been


Abstract After Robert Lowell died, his editor, Robert Giroux, heavily pruned the poet's prose memoir of 1954–1956, "The Balanced Aquarium," for Lowell's posthumous Collected Prose of 1987. This essay considers Giroux's changes and shows his version, titled "Near the Unbalanced Aquarium," to be a dialogical and interactional collaborative auto|biography.


Objective
To explore the relationship between microvascular density(MVD) marked by CD105 monoclonal antibody (mAb) and stages of cervical cancer, clinical pathological factors.

Methods
From September 2005 to January 2009, cervical cancer specimens were stained by immunohistochemistry of CD105 monoclonal antibody marked by microvascular density in 30 cases of carcinoma in situ(stage 0), 15 cases of early invasive cervical cancer (stage ⅠA) and 35 cases of invasive cervical cancer (stage ⅠB-ⅡB). Furthermore, 50 cases with invasive cervical cancer were divided into group grade Ⅰ(n=5), group grade Ⅱ(n=35) and group grade Ⅲ (n=10) according to pathological grade of malignant tumor, and node-positive group (n=8) and node-negative group (n=42) according to lymph node metastasis. The expression of the vascular endothelial cell marked by CD105 monoclonal antibody in tumor interstitium of carcinoma in situ, early invasive cervical cancer, and invasive cervical cancer were detected by immunohistochemical SP method. Meanwhile, the correlation between the expression of microvascular density marked by CD105 monoclonal antibody in different stages of tumor development and clinicopathological factors was observed.

Results
The microvascular density marked by CD105 monoclonal antibody among carcinoma in situ(n=30, stage 0), early invasive cervical cancer (n=15, stage ⅠA) and invasive cervical cancer (n=30, stage ⅠB-ⅡB) were significant difference(P<0.05). But with the further test of L-S-D, microvascular density had no significant difference between carcinoma in situ and early invasive cervical cancer (P=0.528). Microvessel density in lymph node positive group was higher than that of lymph node negative group(P=0.035), and among group grade Ⅰ, group grade Ⅱ and group grade Ⅲ had no significant difference (P=0.059).

Conclusion
Microvascular density marked by CD105 is relative to clinical stages and prognosis of cervical cancer. It will give the therapy theory evidence of carcinoma in situ and early invasive cervical cancer.

The removal of organosulphur from gasoline by adsorption onto commercial carbon samples loaded with different amounts of silver nitrate was investigated. The pore structures of the samples were characterized by nitrogen adsorption studies, while the structure and chemical property of the samples before and after adsorption were examined and analyzed by XRD, FT-IR and SEM methods, respectively. The results showed that silver formed π-complexes with organic sulphides; the higher the silver loading, the greater the amount adsorbed. However, the adsorption selectivity was poor.


At present lecturing is the main approach in class teaching in universities, with little active participation of the students. This paper explores, with appreciation of films and television programs as an example, the construction and Practice of the teaching of task-driven cooperative learning for two purposes: one is the possibility and efficiency in practice and the other is its popularization through the research of its feasibility.


This research is motivated by the low value of daily test of students on the subject of Equation of Straight Line which is more than for half does not reach the minimum completeness criteria (KKM) of the set standard is 70.00. The low learning outcomes of students indicate that the learning process has not run optimally. Therefore, in need of learning alternatives that support students to think creatively, to improve the KKM, one of them using Search model, solve, create, and share (SSCS). This study aims to determine the improvement of students' creative thinking ability by using SSCS learning model on straight-line equation. This research is a Classroom Action Research (PTK). Carried out in three cycles. Cycle 1 consists of two meetings, cycle 2 and cycle 3 each consisting of one meeting. Instruments used to collect data consist of creative thinking ability test, instructional learning observation sheet with SSCS model, and student response questionnaire to learning with SSCS model. The results obtained from this research are 1) students' creative thinking ability increases after learning by using SSCS learning model; 2). Student learning completeness on the subject The equation of Straight line increases after learning with SSCS learning model; 3) students respond positively to mathematics learning using SSCS method

The case concerns a woman 30 years old who died following a 4-months period of taking Conovid E as a contraceptive. The right lower lobe of the lung showed an infarct the left pulmonary artery contained an embolus and the left external iliac vein had a thrombosis.


This research work developed two new dead oil viscosity correlations: a general correlation and typical Niger Delta crude correlation, with large data range. The dead oil viscosity, affects the accuracy of viscosity models, especially when used in engineering problems involving fluid flow in porous media and particularly reservoir simulation. An accurate estimate of its value is therefore a very necessary concern. The models were developed using Linear and Non-Linear Multiple regression analysis. Multiple statistical assessments were employed to evaluate the accuracy of these models. The models are solved using Matlab and Microsoft Excel to obtain the General Model correlation coefficient of 0.870 and that of Typical Niger Delta Crude coefficient of correlation was 0.94. The models also gave better performance plots compared to existing models. Keywords : viscosity, fluid flow, crude oil, Niger delta, dead oil viscosity, reservoir


Student dropout in higher education is a complex issue and as a process it includes many factors which may affect each other. This paper explores the use and application of a probabilistic supervised machine learning technique for predicting university student dropout to obtain insights on the students at risk and prevent them from dropping out the studies. Data from a public university in the Republic of Kosovo were obtained and examined. The dataset comprises instances of students' dropouts for the past six academic years along with their demographics, grades, enrollment details etc. Logistic Regression, as one of the most widely used Machine Learning and Artificial Intelligence algorithms, was used to build the model and produce the predictions. First, a statistical analysis was conducted and after the data preprocessing, logistic regression classifier was implemented. The results show that a high prediction accuracy was reached, with a percentage of 90%, and a F1 score of 0.85, indicating that the model is performing great and the predictions results are reliable.


Aim  The study and prediction of species–environment relationships is currently mainly based on species distribution models. These purely correlative models neglect spatial population dynamics and assume that species distributions are in equilibrium with their environment. This causes biased estimates of species niches and handicaps forecasts of range dynamics under environmental change. Here we aim to develop an approach that statistically estimates process-based models of range dynamics from data on species distributions and permits a more comprehensive quantification of forecast uncertainties.

Innovation  We present an approach for the statistical estimation of process-based dynamic range models (DRMs) that integrate Hutchinson's niche concept with spatial population dynamics. In a hierarchical Bayesian framework the environmental response of demographic rates, local population dynamics and dispersal are estimated conditional upon each other while accounting for various sources of uncertainty. The method thus: (1) jointly infers species niches and spatiotemporal population dynamics from occurrence and abundance data, and (2) provides fully probabilistic forecasts of future range dynamics under environmental change. In a simulation study, we investigate the performance of DRMs for a variety of scenarios that differ in both ecological dynamics and the data used for model estimation.

Main conclusions  Our results demonstrate the importance of considering dynamic aspects in the collection and analysis of biodiversity data. In combination with informative data, the presented framework has the potential to markedly improve the quantification of ecological niches, the process-based understanding of range dynamics and the forecasting of species responses to environmental change. It thereby strengthens links between biogeography, population biology and theoretical and applied ecology.


This study compares human resource management (HRM) practices in Indian public- and private-sector organizations. The investigation is based on a questionnaire survey of 137 large manufacturing firms (public sector=81; private sector=56). The key areas of analysis include the structure of human resource (HR) department, the role of HR function in corporate change, recruitment and selection, pay and benefits, training and development, employee relations and emphasis on key HRM strategies. Internal labour markets (ILMs) are used to make the comparative analysis. The statistical results show a number of similarities and differences in the HRM systems of Indian public- and private-sector organizations. Against the established notion, the results of this study reveal that the gap between Indian private- and public-sector HRM practices is not very significant. Moreover, in a few HR functional areas (for example, compensation and training and development), Indian private-sector firms have adopted a more rational approach than their public-sector counterparts.

This study was conducted to investigate the efficiency of water quality remediation and the inorganic ion removal characteristics by floating plant; water lettuce (Pistia stratiotes L.) in a batch reactor. Water lettuce can be used to remove N and P and other inorganic nutrients, by consuming them in the form of plant nutrient. The highest nutrient absorption of water lettuce was 112.5 meL?¹ N in Sonneveld-2S, 56.6 meL?¹ N in Sonneveld-1S, 31.8 meL?¹ N in sewage and P value was also the highest in Sonneveld-2S as 15.6 meL?¹ and in sewage as 5.0 meL?¹. These results indicated that using water lettuce held some promise in the context of purification of eutrophication. Also water lettuce had a preference for absorption N. Under Sonneveld-2S treatment, nitrogen percentage was the highest in plant tissue due to the highest concentration of nitrogen and removal by water lettuce. Under sewage, percentage of total N in both plant parts was high. Both above and underground parts, P percentage was less than N. It might be due to the fact that the absorption amount of P was less than N by water lettuce. It meaned that the ability of N removal by water lettuce was higher than that of P, relatively. In summary, these results show that the use of this plant was a viable option.


The most recent report card on the Great Barrier Reef 's water quality highlighted major changes that need to be made to meet targets by 2018. Sediment and pollutant runoff from land use have increased 2-3 fold since 1850, largely driven by agricultural land clearing and grazing, while fertiliser used in sugar cane farming contributes to nitrogen runoff.

Porokeratosis (PK) is an uncommon disorder of keratinization that presents with keratotic papules or annular plaques that expand centrifugally with a thread-like elevated border. Genital involvement in PK is a rare occurrence even in disseminated forms. We encountered two patients who had PK primarily affecting the genital area. Both cases were males out of which one case had involvement of the scrotum and thigh and other case had only scrotal involvement. The cases were difficult to diagnose clinically, but dermoscopy was helpful and was further confirmed on histopathology.


Abstract The following question has been considered by several mathematicians over the last half century: How many incongruent triangles with integer sides have perimeter n? We present a new solution based on group actions and orbit enumeration.


The electronic spectra double wall carbon nanotubes using tight binding approximation are investigated. We focus on the double wall armchair nanotubes. The influence of nanotube curvature on the electronic spectra is also treated. The impact of the external magnetic field on the spectral characteristic of double wall nanotubes is computed. We found the big change of the electronic spectra for the double walled carbon nanotubes due to the external magnetic field.


When the world is facing the COVID-19 pandemic, society is also fighting another battle to tackle misinformation. Due to the widespread effect of COVID 19 and increased usage of social media, fake news and rumors about COVID-19 are being spread rapidly. Identifying such misinformation is a challenging and active research problem. The lack of suitable datasets and external world knowledge contribute to the challenges associated with this task. In this paper, we propose MiCNA, a multi-context neural architecture to mitigate the problem of COVID-19 fake news detection. In the proposed model, we leverage the rich information of the three different pre-trained transformer-based models, i.e., BERT, BERTweet and COVID-Twitter-BERT to three different aspects of information (viz. general English language semantics, Tweet semantics, and information related to tweets on COVID 19) which together gives us a single multi-context representation. Our experiments provide evidence that the proposed model outperforms the existing baseline and the candidate models (i.e., three transformer architectures) and becomes a state-of-the-art model on the task of COVID-19 fake-news detection. We achieve new state-of-the-art performance on a benchmark COVID-19 fake-news dataset with 98.78% accuracy on the validation dataset and 98.69% accuracy on the test dataset.


The authors studied the correlation between cortisol production, as measured by an isotope dilution method, and the urinary excretion of total and free Porter-Silber chromogens, as well as of 17-ketogenic steroids. Although a significant correlation exists between total Porter-Silber chromogens, 17-ketogenic steroid excretion and cortisol production, discrepancies are occasionally observed. Hence, different colorimetric methods should be used to assess the glucocorticoid activity of the adrenal cortex. The evaluation of the adrenocortical glucocorticoid activity is generally based on the colorimetrie determinations of the urinary metabolites of the adreno¬ cortical hormones. The specificity of these colorimetrie determinations, how¬ ever, is rather limited as they represent group reactions dependent on the presence of some functional groups on the steroid nucleus. It should be remembered that the adrenocortical hormones are inactivated along multiple pathways; alterations in the metabolism or perhaps physiolo¬ gical shifts in the relative importance of these inactivation reactions might result in a decreased excretion of metabolites with a particular functional group, without producing any change in the hormonal secretion rate. Moreover the colorimetrie reactions can be disturbed by the presence of non specific chromogens, causing falsely high results. It has therefore been re¬ commended that certain drugs should be avoided when these determinations
