The experience of "coming out" (CO) to parents is often a crucial event in the lives of lesbian and bisexual (LB) women, associated with lower internalized sexual stigma (ISS) and higher positive LB identity. Few studies have compared the experiences of LB women in the CO process. Rather, most prior research has either: (1) not addressed bisexuality or eliminated bisexual individuals from the analysis; (2) combined bisexual women and bisexual men in the same sexual orientation group; or (3) examined bisexual participants alongside lesbian women and gay men, using a single monolithic measure. Thus, the present research aimed at investigating the role of ISS and positive LB identity in inhibiting or encouraging CO to parents in a sample of 241 lesbian women (Mage = 27.61, SD = 7.19) and 186 bisexual women (Mage = 25.23, SD = 5.81), aged 18–40 years. Most participants reported that they had already revealed their sexual orientation to their mother (69%) and their father (52%). More lesbian women had CO to both their mother and their father than had bisexual women. These lesbian women reported lower levels of ISS and higher levels of LB positive identity relative to bisexual women. On average, CO to mothers occurred at age 20 (SD = 5.54), while CO to fathers occurred at age 22 (SD = 5.63). LB women did not differ in the average age of CO to mothers or fathers, or in parental reactions to CO. Finally, ISS was found to affect the process of CO to both parents via positive identity (bootstrapping estimate = −0.26, SE = 0.08, 95% CI = −0.43, 0.11), whereas sexual orientation was not found to moderate the path from ISS to CO to both parents. The present study contributes to our understanding of the differences between LB women when developing their sexual orientation, highlighting the relevance of a positive LB identity for CO to parents. Research and clinical implications and directions for future research are discussed.


The invention relates to a non-contact three-dimensional displaying simulative teaching system, comprising a host computer, and a back-projection device, a touch screen and a camera which are communicated with the host computer. A camera mode identifying module is arranged in the host computer, and an action model databank corresponding to relevant operations is arranged in the camera mode identifying module to identify action information in image signals collected by the camera and to inquire whether the collected action information matches the action model of the action model databank, and when the matched action model is found, the operation corresponding to the action model is executed. The back-projection device comprises a projector, a reflector and a back-projection screen. After the signal from the host computer is reflected by the reflector, the signal is projected to the back-projection screen by the projector. The system of the invention applies the back-projection system to multimedia teaching to lead the free moving of teacher before projection screen not to block the beam of projector so as to avoid the defect of front-projection, thus realizing timely and interactive control to objects and resulting in a more effective teaching course.

Abstract We describe the construction of ab initio databases that can be used for fitting and testing empirical atomistic potentials. In particular, we show how the use of a large ab initio database can overcome the problem of overfitting an empirical potential to a limited set of data.


This study gives an overview of the US government market promotion programs for peanuts as well as the US trading position in international peanut markets. FAS data on the Cooperator (CMDP), Targeted Export Assistance and Market Promotion Programs (TEA|MPP) were examined to identify how program expenditures have been allocated among regions and activities. Analysis shows that during the 1986-1991 period, three-quarters of CMDP, TEA, and MPP funding for peanuts was directed to the European Community, the largest US peanut export market. Moreover, branded consumer promotion has accounted for a large percentage of program expenditures worldwide. © 1993 John Wiley & Sons, Inc.


The article examines the social aspects of the housing problem in modern Russia and the impact of housing supply on demographic characteristics, social reproduction, and mentality. The author justifies the importance of sociological studies of the housing problem. Details of the results of the panel survey, conducted in 2008 and 2013, are highlighted in the article. The purpose of the survey was to investigate the satisfaction of the residents of the city of Tyumen with their accommodation, their prospects for improvement, and the relationship to the state program "Affordable Housing". In particular, the article dwells on the awareness of the citizens of the implementation of the priority national project, the evaluation of the implementation of individual program areas (modernization of housing and services, the use of maternity capital, benefits for individual housing for large families, the increase the availability of mortgages, housing provision for public sector employees and etc.), the obstacles to implement the program "Affordable Housing" and the intentions of the citizens in terms of improving their living conditions in the next 5-7 years and the ways of acquiring public housing. The results of the survey suggest that over the last 5 years there has been a significant improvement in public opinion ratings of individual results of the program. The citizens of Tyumen considered the programs to improve the living conditions of young families and public sector employees as the most effective, while at the same time their relation to mortgage, which has recently become a real tool for improving the living conditions, is rather negative.


We address an interesting case – the predictability of excess US asset returns from macroeconomic factors within a flexible regime-switching VAR framework – in which the presence of regimes may lead to superior forecasting performance from forecast combinations. After documenting that forecast combinations provide gains in predictive accuracy and that these gains are statistically significant, we show that forecast combinations may substantially improve portfolio selection. We find that the best-performing forecast combinations are those that either avoid estimating the pooling weights or that minimize the need for estimation. In practice, we report that the best-performing combination schemes are based on the principle of relative past forecasting performance. The economic gains from combining forecasts in portfolio management applications appear to be large, stable over time, and robust to the introduction of realistic transaction costs.

ABSTRACT We investigated the feasibility of a formative objective structured clinical examination adapted for social work (OSCE-SW) with a parent–bisexual child dyad and evaluated self-efficacy and performance learning outcomes for undergraduate social work students. Eighteen undergraduate students participated in a simulation involving two embedded participants. Participants received an average score of 35.7 out of 50 potential points on the performance rating scale during a 15-min OSCE-SW scenario. We observed no change in self-efficacy before and after the OSCE-SW experience. The authors recommend implementing additional dyadic OSCE-SW scenarios, including scenarios focused on parent–bisexual child relationships and other types of marginalized dyadic relationships.


The act of sound perception and its subjective dimensions, from physical to psychoacoustics, from semantic to affective, carry an inherent challenge for the conception and evaluation of every audio-based artefact. Starting from a previous framework of evaluation approaches, we seek to deconstruct the confguring elements of these processes, searching for theoretical foundations informing Sound Design and possible applications for Auditory Displays. This work is a first step into identifying a body of knowledge on the listener's experience, how the act of listening takes place and how the sequence of listening actions can evolve as forms of dialogue, creating dialogical spaces for making sense of auditory information. With this work, practitioners can gain new insights into how existing techniques for creating auditory artefacts can be confgured and transformed into new, alternative approaches.


Handwriting analysis and the identification of people based on individual typing patterns are of great interest in the field of biometrics. The increasing need for user authentication in our modern society has underscored the need for smarter and more automated security protocols. The goal of this research is to explore the feasibility of using relatively inexpensive commercial smartwatches as a reliable platform for transcription-based biometrics. This study demonstrates that it is possible to accurately identify individuals performing transcription tasks (i.e. handwriting sentences, typing on a keyboard, etc.) using only a smartwatch.


Summary Normal, malignant, and transformed cell lines have been studied for variations in 3 different enzyme activities, GO-T, GP-T, and LD. Only LD activity changed during the growth period. The enzyme activity both in the cells and in the fluid bathing them was greatly increased in the malignant cell lines and in 2 transformed lines, in contrast to the normal cell lines and the conjunctiva cell line where large quantities did not appear in the media. The increase in LD activity was found to be related to the cellular growth rate rather than to be a characteristic of the cell, since the normal cells in most instances were found to contain more enzyme activity per cell than the malignant ones.

We construct a semi-classical parametrix for the Laplacian on non-trapping asymptotically hyperbolic manifolds, which generalizes the construction of Melrose, Sa Barreto and Vasy. As applications, we obtain high energy resolvent estimates and resonance free strips. Also, we prove that the Friedlander radiation field decays exponentially for initial data in proper spaces.


Objective: This research aims to help explore the theoretical and practical development of Red Tourism Industry in Jiangxi Province, to further improve Red Cultural Industry's cluster degree and make full use of its cluster effect, to strengthen the self-innovation advantages of Red Culture Industry, to form multi-industrial, cross-regional and brand competitive leading industries, and finally to push forward the sustainable development of Jiangxi's Red Cultural Industry. Methods: Through observation and historical analysis, this research adopts a series of methods such as doing interviews, surveys and individual case analysis, explores and analyzes the developing law of Red Cultural Industry. Results: According to the surveys, tourism economy has been developing steadily. In 2012, there were only about 25 million domestic tourists while by the first half of the year 2017, the number has risen to 2.537 billion, nearly one hundred times more than that of 2012; In 2012, the domestic tourism revenue was around 20 billion yuan while by the first half of the year 2017, the number has risen to 2.17 trillion yuan, also more than one hundred times bigger than that of 2012. All the figures point out the good results brought by cluster industries in tourism. However, the development of Tourism is also influenced by some other factors. So how well cluster industry has played in Red Culture Tourism's development are also still needs further and deeper investigation and analysis. Conclusion: Industry cluster is an industrial chain associated with enterprises, research and development and service organizations in specific regions. Through the division of labor, cooperation and collaborative innovation, it forms a multi-industrial, cross-regional and internationally competitive industrial organization. Based on the perspective of industrial clusters, the upgrading research of Red Tourism Industry's developing mode not only promotes the rapid and sustainable economic development of Red Tourism in industrial cluster zones, but also bears great significance in the theoretical structural construction of Red Tourism Industrial Clusters and its practical use in reality. The Theoretical Basis of Tourism Cluster Industries The Concept and Connotation of Tourism Cluster Industries. According to Michael Port (1998), the professor of Harvard University, Cluster Industries are the phenomenon where a large number of industry-related enterprises and related support institutions (including research institutions) are agglomerated in space to form a strong and sustained competitive advantage through synergies in a particular area (usually dominated by a leading industry). Cluster Industries also include a number of interconnected industries and other entities that play an important role in competition. [1] In other words, cluster industries include both upstream and downstream enterprises, suppliers of complementary products, suppliers of specialized infrastructure, and other institutions that provide training, education, information, research and technical supports. However, the cluster of tourism industry did not show the input and output among enterprises or the supply chain of upstream and downstream. However, a large number of tourism service enterprises and other related institutions mostly formed a network or vertical distribution around tourist destinations, which is a concentration effect in specific regions, and provides tourists with spatial aggregation of various 8th International Conference on Social Network, Communication and Education (SNCE 2018) Copyright © 2018, the Authors.

Carton folding is a packaging operation performed by human operators or with fixed automation. We present a flexible method to fold cardboard cartons using fixtures. A carton blank is folded by moving it through a fixture with a robot. This method of using interchangeable fixtures enables rapid changeovers between product models. We outline a procedure to design a fixture given a carton and a folding sequence. We present an implemented motion planning algorithm that generates all folding sequences for a carton by modeling it as a many degree of freedom robot manipulator with revolute joints and branching links. A fixture constrains the carton to move along paths consisting of line segments in its configuration space, and the motion planner generates these paths. To illustrate the method, we selected a folding sequence for an example carton, designed a fixture, and demonstrated folding of the carton from blanks with an industrial robot.


Abstract: The unplanned application of pesticide in paddy crop field to enhance paddy production could cause adverse impact on the environment. The present study was aimed to isolate the bacteria prevalent in profenofos applied soil to determine their profenofos degrading ability and its assay of the degraded metabolites. The dominant bacteria isolated from paddy crop field soil were Bacillus cereus and Aneurinibacillus migulanus. These bacteria were spiked with profenofos. After 36 hours of incubation in soil the extract were analysed by GCMS. Profenofos degradation was enhanced by Aneurinibacillus migulanus (99.45 % of profenfos degraded) compared to Bacillus cereus (98.01 %) and control (88.46%). Thus Aneurinibacillus migulanus could be used as bioagents to degrade profenofos.


In this communication, we report novel, simple and effective methodologies for the incorporation of functional metal nanoparticles in carbon nanotubes/epoxy nanocomposite electrodes. The incorporation of nanoparticles was obtained by three different routes: (a) in situ functionalization of carbon nanotube surfaces, (b) incorporation and dispersion into a composite matrix and (c) composite surface modification by drop-attachment. These techniques offer a customized route for the preparation of sensitive amperometric sensors. Independent of the route of noble metal nanoparticle incorporation, the final result is a significant enhancement of the electroanalytical response.

The nonisothermal crystallization kinetics of poly(ethylene terephthalate) (PET) and poly(methyl methacrylate) (PMMA) blends were studied. Four compositions of the blends [PET 25/PMMA 75, PET 50/PMMA 50, PET 75/PMMA 25, and PET 90/PMMA 10 (w/w)] were melt-blended for 1 h in a batch reactor at 275°C. Crystallization peaks of virgin PET and the four blends were obtained at cooling rates of 1°C, 2.5°C, 5°C, 10°C, 20°C, and 30°C/min, using a differential scanning calorimeter (DSC). A modified Avrami equation was used to analyze the nonisothermal data obtained. The Avrami parameters n, which denotes the nature of the crystal growth, and Zt, which represents the rate of crystallization, were evaluated for the four blends. The crystallization half-life (t½) and maximum crystallization (tmax) times also were evaluated. The four blends and virgin polymers were characterized using a thermogravimetric analyzer (TGA), a wide-angle X-ray diffraction unit (WAXD), and a scanning electron microscope (SEM). © 2006 Wiley Periodicals, Inc.

Fatty acid peroxides are formed when liver, kidney, and brain homogenates or slices are incubated aerobically (1). The peroxides inhibit certain mitochondrial enzymes (2), and the inhibition is prevented by previous addition of glutathione but only partially reversed by it (unpublished). Peroxides react slowly with enzymes in vitro, and when small amounts are injected into animals death occurs in 20 to 40 hours, depending on the dosage (unpublished). Peroxides also inhibit the growth of certain bacteria (3) and cell division in marine worm eggs (4). Because of these effects the organism must have mechanisms to prevent accumulation of peroxides under normal conditions. It seemed likely that such mechanisms would be particularly effective in tissues where cell division is occurring, and it has already been shown (5) that Ehrlich tumor cells produce no peroxides on incubation. In the present study peroxide formation has been investigated in normal, actively dividing bone marrow and in the marrow of X-rayed animals. The peroxides were estimated by the thiobarbituric acid reagent (6).

For the centralized PV station which uses panels constructed with by-pass diode, the mathematical model of U-I relationship is established considering mismatch. Measured values of output voltage and current are obtained by real-time measurement system. Then the equation set is formed and can be solved via Gauss-Seidel iteration method. Thus, five parameters and mismatch parameter are available, and can be used to judge the mismatch panel or panels. Moreover, database can be set up according to the relation between the environment circumstance and the five parameters, which can efficiently improve the time of mismatch detecting.


In every application, power management must take precedence, whether to reduce energy use or to minimize heat dissipation to lower cooling and packaging costs. Power management is becoming an increasingly urgent problem for almost every category of design, as power density, measured in watts per square millimeter, rises at an alarming rate. From a chipengineering perspective, effective energy management for a SoC (System-on-a-chip) must be built into the design starting at the architecture stage; and low-power techniques need to be employed at every stage of the design, from RTL (Register Transfer Level) to GDSII. Power needs to be considered at the very early stages of a design, when the opportunity to save power is at a maximum. At the same time, making a design extremely power efficient results in trading off area and/or timing. A balanced approach is warranted when it comes to power optimization that spans across the entire RTL-to-GDS flow. Today, with the dramatic increase in power requirements, power management is becoming an important aspect for almost all categories of design. The popularity of cell phones, MP3 players, PDAs and other handheld devices has made extended battery life a major selling point for portable systems. Increasing awareness of global warming and green technology is also driving the demand for low-power designs. The rising energy costs and geopolitical forces are causing everyone to rethink how they consume power. As a result, semiconductor and EDA vendors are developing new methodologies and tools that allow them squeeze as much as they can from tightening power budgets.This paper survey recent research on CMOS low voltage and low power ICs


This study focuses on identifying the optimum conditions of sewage sludge hydrothermal carbonization by Box–Behnken Design and on the effects of volatile solids on heating value and on process water load. To get insight into the solid and process water characteristics, we applied the Box–Behnken Design on the hydrothermal reaction temperature (190, 220, 250 °C), reaction time (0.5, 2.25, 4 h) and pH (3.9, 5, 6.1). The response surface of the liquid phase revealed decreasing dissolved organic carbon (DOC) concentrations with increasing temperature from 9446 mg/L (190 °C) to 7402 mg/L (250 °C) at 4 h reaction time. For the same hydrothermal conditions, NH4-N concentration increased from 754 to 1230 mg/L. Reaction temperature was identified as the most important process parameter, whereas reaction time and pH had only minor effects. Moreover, linear coefficients of the models were more decisive than the interrelation and quadratic coefficients. Volatile solids (VS) of the feedstock were found to significantly influence both the load of the process water and the change in heating value of the hydrochars. Process water load increased steadily with higher VS. The heating value only increased with more than around 65–80% VS in feedstock.


The present invention relates to a WNT10-derived peptide, a composition for improving hair loss and skin conditions using the same, and a composition for treating a WNT10 signal transduction pathway-related disorder and DKK-1 protein-induced disorder using the same. WNT10-derived peptide of the present invention possesses identical or similar activities to natural-occurring WNT10, and has much higher stability and skin penetration potency than natural-occurring WNT10. Therefore, the composition containing the present peptide not only shows excellent effects on improvement in hair loss (for example, promotion of hair growth or production of hair), but also has superior efficacies on treatment of a WNT10 signal transduction pathway-related disorder and a DKK-1 protein-induced disorder. In addition, the outstanding activity and stability of the present peptide described above may be greatly advantageous in application to pharmaceutical compositions, quasi-drugs and cosmetics.


Let $(u, \pi)$ with $u=(u_1,u_2,u_3)$ be a suitable weak solution of the three dimensional Navier-Stokes equations in $\mathbb{R}^3\times [0, T]$. Denote by $\dot{\mathcal{B}}^{-1}_{\infty,\infty}$ the closure of $C_0^\infty$ in $\dot{B}^{-1}_{\infty,\infty}$. We prove that if $u\in L^\infty(0, T; \dot{B}^{-1}_{\infty,\infty})$, $u(x, T)\in \dot{\mathcal{B}}^{-1}_{\infty,\infty})$, and $u_3\in L^\infty(0, T; L^{3, \infty})$ or $u_3\in L^\infty(0, T; \dot{B}^{-1+3/p}_{p, q})$ with $3<p, q< \infty$, then $u$ is smooth in $\mathbb{R}^3\times [0, T]$. Our result improves a previous result established by Wang and Zhang [Sci. China Math. 60, 637-650 (2017)].

Thirtyfive patients with chronic peripheral arterial disease (10 Stage II, 23 Stage III and IV, 2 acute occlusions) were treated with brinase. Arteriosclerosis was the cause of disease in 27 patients, 8 had non-arteriosclerotic obstructions (5 thrombangiitis obliterans, 2 necrotizing vasculitis and 1 systemic lupus erythematodes). Twentyfive patients received full series of brinase treatment, in 10 patients treatment was discontinued (4/10 of reasons related to treatment). Twenty patients were treated by i. v. brinase infusions. Dosage was based on determination of the brinase inhibitor capacity in plasma. In 5 cases brinase was instilled intra-arterially during vascular surgery, treatment was continued by i. v. brinase infusions. All patients except two were anticoagulated (dicoumarol and/or heparin). After initial arteriography the patients were followed by peripheral blood pressure measurement and in part by dynamic fluorescein angiography. Patients, treated peroperatively with brinase, were examined by electromagnetic flowmetry. At termination of brinase treatment 20/25 patients showed clinical improvement. Increase of flow in the superficial femoral artery was recorded after peroperative intra-arterial instillation of brinase. The blood pressure gradient (arm-leg) before treatment (25 patients) was 112±24 mmHg. In patients with arteriosclerotic obstructions showing clinical improvement (14/19) the gradient was lowered to 49±20 mmHg, as compared to 112±27 mmHg in clinical failures. In patients with non-arteriosclerotic occlusions (6/6 improved) the gradient was lowered to 32±21 mmHg. Fluorescein angiography indicated improved microcirculation. Bleeding complications were not observed.

Introduction: It is a standardized practice to monitor blood glucose (BG) levels while on insulin infusion therapy in patients who undergo open heart surgery regardless of their diabetes status. Hyperglycemia was often noted in these patients due to catecholamine surge induced by intraoperative stress. This study is to investigate whether using Continuous Glucose Monitoring (CGM) is a safer option compared to traditional finger stick (FS) glycemic monitoring in postoperative patients. Methods: This is a prospective randomized controlled trial. Patients planned for open heart surgery including coronary artery bypass surgery, valvular repair, or replacements at UPMC Harrisburg hospital from May 2021 to August 2022 were voluntarily involved and randomized by 2:1 ratio into CGM or FS glycemic monitoring methods during the first 48-hour postoperative period on insulin infusion therapy and in the intensive care unit (ICU). Patient demographics, comorbidities, diabetes (DM) status, and glycemic data within the first 48 hours after surgery were compared between the two groups. Results: A total of 42 patients were recruited, including 31 males (81.6%). Four patients were excluded due to missing data, 22 were randomized to the CGM group, and 16 to the FS group. There was no difference in demographics between the two groups. The mean glucose level of the CGM group (123.09 mg/dL) was no different from the FS group (116.31mg/dL) (p=0.09). The CGM group detected significantly more events of level 2 hypoglycemia (BG <54 mg/dL, p=0.01) and hyperglycemia (BG>=180 mg/dL, p=0.01) compared to the FS group. In the CGM group, the mean time of normoglycemia (BG 70-179 mg/dL), hypoglycemia, and hyperglycemia in all 22 patients was 91.1%, 2.58%, and 6.34% respectively. Time in normoglycemia was longer in non-DM patients (95.8%) than in DM patients (87.1%). Discussions: CGM signatures the convenience of frequent BG checks, enabling the reduction of glucose variability and improvement of glycemic control. In this study, although no difference was noted in the mean BG between CGM and FS groups, CGM was noted to be especially effective in hypoglycemia detection. Our findings suggest that CGM brings in the potential benefit of improving patient safety compared to traditional glucose monitoring.

The preparation of a high-functional polymer membrane inside the microchannel is one of the promising ways to integrate complicated chemical processes into microchips, which allows us a wide variety of applications in this research field. Here, we focus on the laminar flow formed inside the microchannel by the introduction of an organic solution and an aqueous solution to prepare the high-functional polymer membrane by interfacial polycondensation. In this study, we prepared a nylon membrane in the microchannel by interfacial polycondensation under the laminar flow condition.


With the continuing advancement in material technology and construction techniques, architects face a greater set of options and challenges when it comes to designing in historic settings. In the meantime after the ICOMOS agreement, every country adapted the policy according to their own culture and settings, therefore every architect in their respective country started interpreting the charters, and the design review processes in their own way. Working on the new addition to historic context gave rise to familiar characteristics in design, especially in the infill designs, which is "Replication and Contrast", which in turn sparked the question, how to evaluate whether a building is properly fitting in its context with whatever approach employed. This paper aims to answer this question by conducting a literature review covering First, the qualitative evaluation approach which compromises of surveys and pre-visualization in order to identify the main visual properties that improve the contextual compatibility of the new designs in the historical context, and quantitative techniques focused more on the mathematical scientific cognitive results of all aspects of the architectural elements within historic settings. A comparison has been made on each result achieved and an assessment of their reliance or authenticity has been tested in order to find and bridge the gap between tangible and intangible values when judging "fit" in a historic setting. The results showed that the qualitative evaluation if followed properly it could be very promising, but it always leaves room for skepticism as the result is expected to change based on the size and the characteristics of the participants. The quantitative evaluation provided a more tangible evidence of the contextual fit in terms of architectural elements like size, proportion, and scale. Finally, a suggestion was made in order to provide a better, and a more comprehensive technique merging both methods together and trying to incorporate more of three-dimensional aspects of the building instead of the two dimensionality of the current assessment techniques.

In this paper, we present a checkpoint-based scheme to improve the turnaround time of bag-of-tasks applications executed on institutional desktop grids. We propose to share checkpoints among desktop machines in order to reduce the negative impact of resource volatility. Several scheduling policies are evaluated in our study: FCFS, adaptive timeouts, simple replication, replication with checkpoint on demand, and prediction-based checkpointing combined with replication. We used a set of real traces collected from an academic desktop grid environment to perform trace-driven simulations of the proposed scheduling algorithms. The results show that using a shared checkpoint approach may considerably reduce the turnaround time of the applications when compared to the private checkpoints methodology.


In 1940 Vinogradov considered in [1] the problem of the distribution of numbers of the form {f~\f~p}, where ρ ranges over the prime numbers and 0 < / < 1. Since then the distribution of the fractional parts of the sequence p, where α is a fixed non-integer and ρ ranges over the primes, has been studied by numerous authors (see [3] -[6]). In this note we consider a generalization of this problem. We introduce the following notation: aj, ..., oti are real numbers such that

In this thesis, we investigate how protocols in quantum communication theory are influenced by noise. Specifically, we take into account noise during the transmission of quantum information and noise during the processing of quantum information. We describe three novel quantum communication protocols which can be accomplished efficiently in a noisy environment:
(1) Factorization of Eve: We show that it is possible to disentangle transmitted qubits a posteriori from the quantum channel's degrees of freedom.
(2) Cluster state purification: We give multi-partite entanglement purification protocols for a large class of entangled quantum states.
(3) Entanglement purification protocols from quantum codes: We describe a constructive method to create bipartite entanglement purification protocols form quantum error correcting codes, and investigate the properties of these protocols, which can be operated in two different modes, which are related to quantum communication and quantum computation protocols, respectively.


Hidradenitis suppurativa (HS) has prevalence of 0.05–4.1% and is more common in women, with an onset typically occurring after puberty. HS is often under-recognized, mismanaged, and is associated with comorbidities and decreased quality of life. Currently, management is tailored to the phase of the disease; medically treating the inflammatory phase and surgically managing the fibrotic phase. The tissue-sparing surgery can be disfiguring and may not protect against recurrence. The aim of this case series is to highlight a novel therapy as a treatment option for chronic, recalcitrant HS.

 Four HS patients underwent a novel treatment in the burn unit at our institution. Patients underwent excision of wounds, dermal regenerative template (DRT) placement, and were dressed with a silver-impregnated negative pressure therapy wound vac. On hospital day 5 the wound vac was changed and on day 10 the patient returned to the operating room for removal of the silastic layer of the DRT with formal split thickness skin grafting (STSG) over the neodermis and replacement of the silver-impregnated negative pressure therapy wound vac. On hospital day 15, the VAC was taken down, the graft site was transitioned to daily xeroform and bacitracin dressing, and the patients were discharged home.

 Four patients with ages ranging from 27–60 years with an average disease duration of six-years underwent the novel treatment at our institution. Two patients had HS more prominent on the buttock with the other two patients presenting with axilla involvement. One patient had limited range of motion to the shoulders secondary to chronic contractures. All patients had failed multiple local incision and drainage procedures as well as complex medical therapies including but not limited to chronic antibiotic suppression and immunotherapies. Each patient underwent two operative procedures with three patients requiring one additional bedside wound vac change. All patients were discharged home within fifteen days from the initial procedure with acceptable wound coverage.

 Four patients with HS underwent a novel therapy; tolerated the procedures well, had excellent adherence, and were satisfied with the results. This provides evidence for the validity of this therapy utilizing the above described staged operative approach resulting in definitive management and acceptable cosmetic results.

 By utilizing this novel approach and the multidisciplinary burn team, patients who suffer from long-standing HS may have improved quality of life.


The paper takes it as its target to study the efficient microbial membrane with the marine yeast to be applied in BOD sensor for the in-shore seawater fishery.As is seen,biochemical oxygen demand(BOD) is one of the most important and widely used parameters for characterizing the organic pollution of water and sewage in the measurement of biodegradable organic compounds and pollutants of the ground surface and the seawater.To make clear the problem of the growth dynamics of the yeast strains known as the Debaryomyces hansenii,Pichia guilliermondii and Candida parapsilosis in the liquid glucose-peptone medium,we have done experiments and tests on their bio-characteristic features and gained the following results.To be accurate,we have discovered the highest oxidative activity against GGA in the late exponential or early linear growth phase.The developed laboratory-scale models of biosensors for BOD5 detection are based on the receptor elements with the yeast cells of Debaryomyces hansenii,Pichia guilliermondii and Candida parapsilosis.As is found,the biosensor Debaryomyces hansenii based is featured by the highest sensitivity,with the minimal limit of the linear range,accordingly.It is for this feature that we are sure that it is characteristically the best strain among all those we were experimented with.In addition,we have investigated the effects of pH,temperature and the concentration buffers by using the Response Surface Methodology(RSM),while having done a test of the 33 factors we have developed to optimize the testing conditions.The results gained from the above experiments have shown that the optimal conditions should be chosen as follows: the pH value: 7.7;the temperature to be chosen: 20 ℃,the concentration buffers: 40 mmol/L,and the minimally relative error: 1% between the biosensor and BOD5.This optimal strategy is surely to lead to a decrease of the relative deviation from 4% to 0.5%.The above results indicate that it would be possible to use the Debaryomyces hansenii based biosensor as a reliable method for determining BOD in the seawater.What is more,the linearity range prove to be 9.3-422 mg/dm3 in case the glucose/glutamate BOD standard were applied.Such a newly discovered device will be able to provide a low-cost,easy-operated,fast-response,sensitive and reliable method to measure BOD in the seawater.It is also suitable for the on-line measurements.


. I show how the symmetry-breaking of a recently proposed embedding of the standard model of particle physics in E 8 can be explained in terms of the representation theory of the binary tetrahedral group. This finite group provides a link between various types of spin and isospin that can be exploited to 'explain' the chirality of the weak interaction, and the existence of three generations of fermions. Two apparently small technical differences between the finite group model and the standard model turn out to have profound consequences for the ways in which the weak and strong forces create mass.


From the connected crowds that have taken the squares and the networks (from the Arab Spring in 2011 to #NuitDebout in 2016), a feminist and hacker evolution of collective action that is simultaneous in situ and online is enlightened. This article analyzes the characteristics of this "politics of prefiguration" that is tendentially feminist, which gives special relevance to "the personal is political" in the multiplication of voices and non-mediation, in counting and doing, in opposition to the "politics of organization", more ideological, unitary and oriented towards ends. At the same time, it explores the emergence of performative constellations and feminist hashtags that extend into transnational networks, politicizing vulnerability, such as #PrimaveraVioleta in Mexico in 2016 or the Women Strike of 2017 and 2018.

As a new kind of composite structures and its advantages, the using of steel tube confined reinforced concrete (STCRC) columns have received increasing attention in civil engineering. Acoustic emission (AE) technique is applied to monitor the damage process of STCRC columns during an uniaxial compression test. The aim of this study is to investigate the damage evaluation and failure mechanisms of the STCRC columns from the perspective of microscopic damage. Typical AE parameters are extracted to quantify different damage condition and identify the critical point. Peak-frequency analysis classify the damage signal into groups, representing different AE generation mechanisms. Extended AE features, such as the RA value and the average frequency are calculated to discriminate the cracking modes of core concrete. The probability based Gaussian mixture model (GMM) are proposed for unsupervised damage pattern recognition. All presented AE results are good in accordance with the observed experimental outcomes. The AE technology enabled evaluating the damage condition, identifying critical point, disclosing the failure mechanism, and classifying damage modes for steel confined RC columns effectively.


Xie Lingyun and Xie Xuanhui both are pioneer poets who wrote the mountains-and-waters poetry that have far-reaching influence upon the flourish and prosperity of the style in generations to come. Though the poems by Xie Xuanhui showed the signs of imitating those of Xie Lingyun, their poems presented different artistic styles and characteristics due to their different personalities, experiences and the spirit of the time.


Background The piglet is the only model to investigate the immunogenic relationship between Cryptosporidium hominis and C. parvum, the species responsible for diarrhea in humans. Despite being indistinguishable antigenically, and high genetic homology between them, they are only moderately cross protective after an active infection. Methodology/Principal findings Here we examined the degree of passive protection conferred to piglets suckling sows immunized during pregnancy with C. parvum. After birth suckling piglets were challenged orally with either C. parvum or C. hominis at age 5 days. Animals challenged with C. parvum had significant reduction of infection rate, while piglets challenged with C. hominis showed no reduction despite high C. parvum serum and colostrum IgG and IgA antibody. Conclusions/Significance We add these data to earlier studies where we described that infection derived immunity provides partial cross-protection. Together, it appears that for full protection, vaccines against human cryptosporidiosis must contain antigenic elements derived from both species.


Received: 19 March 2020 Accepted: 8 June 2020 With the recent construction boom, the stability of earth-rock aggregate (ERA) structures become a prominent problem. The ERA is essentially a heterogenous aggregate of randomly stacked particles of varied sizes, the gaps between which are filled with liquid and gas phases. However, the existing theories on geotechnical mechanics cannot accurately describe the mechanical behavior of this special material. To solve the problem, this paper treats the ERA as a set of as a set of randomly stacked spheres, which are equivalent to soil and rock particles in the ERA and have the same radius and material properties. Drawing on the particle contact theory, the total number of coarse particles in the ERA was calculated by the probability density function relative to the mean particle size (sieve diameter), followed by derivation of the equivalent radius of coarse particles. Next, the particle shape correction coefficient (PSCC) was introduced to obtain the equivalent shear modulus of the ERA, according to the relationship between mean stress in the ERA and the micro-contact force between particles. After that, the microscale formula of shear wave velocity was deduced from the macroscale formula. Finally, the effects of multiple parameters on shear wave velocity were quantified in details. The results show that the shear wave velocity of the ERA is greatly affected by the void ratio, elastic modulus, and the PSCC, but has little to do with effective internal friction angle, Poisson's ratio, and coordination number of the ERA particles.

We report a 2H nuclear magnetic resonance (NMR) investigation of 2,3,7,8,12,13-hexakis(octadecanoyloxy)truxene (TxHA17) specifically labeled in the a-position of the alkyl chain. Results from these measurements, together with polarizing microscopy, show that the substance is in a crystalline state up to 90 "C. At this temperature the compound melts and a uniaxial discotic mesophase appears. The liquid crystalline phase persists until the clearing point at 191 "C. The differential scanning calorimetry thermograms confirmed these transitions but exhibited additional peaks below 90 "C. The phase behavior at low temperatures (<90 "C) differs significantly from previous reports by Warmerdam et al. (Liq. Cryst. 1988, 3, 149 and 1087). Solid-state deuterium line shape simulations were used to examine the motions of the labeled methylene site. A Gaussian libration model gave excellent agreement between experimental and calculated 2H NMR spectra. A pronounced spatial inhomogeneity of the motion was found in the high-temperature region of the solid phases. By combining line shape simulations with nuclear spin relaxation measurements, mean correlation times for the a-site could be estimated. It was shown that there exist, even at -100 "C, fast motions of the a-deuterons with rates relatively close to the Larmor frequency. Deuterium NMR spectra of benzene-& dissolved in protonated TxHA17 are also reported. These spectra were interpreted using a model in which the benzene molecules occupy two solvation sites: (i) intercalated within the columns of TxHA17 and (ii) dissolved in the aliphatic chains. The exchange of c& between the two sites is slow on the NMR time scale in the crystalline phase whereas it is fast in the mesophase.

PurposeThe purpose of this study is to examine the effects of brand origin (BO) misperception (hereafter BOM) or non-identification on brand equity. Besides, the current study investigates the moderating role of brand strength in the relationship between BOM and brand equity.Design/methodology/approachThe current study adopted a 4 (BO identification: favorable BOM vs adverse BOM vs non-identification vs correct identification) × 2 (brand strength: strong vs weak) between-subjects design. A total number of 547 participants performed assessments on the automotive brand. The current study selected three strong brands and three weak brands for tests. In the experiment, respondents had to associate the brand with its country of origin. The assignment of BO conditions was based upon respondents' natural responses provided. ANOVA was used for data analysis.FindingsThe results indicate that as compared to correct BO identification, BOM (either adverse or favorable) or non-identification exerts a more negative impact on brand equity. Moreover, the study demonstrates that brand strength moderates the effect of perceived BO on brand equity.Originality/valueThis study provides empirical support to the notion that BOM is detrimental to brand equity. Specifically, when adverse BOM occurs, a strong brand suffers more from the negative consequences resulted than a weak brand does. Conversely, when consumers misattribute the BO to a country with a stronger image than its real origin (i.e. favorable BOM), the resulting negative effect is reversed. Moreover, the non-identification of BO hurts the brand equity of both strong and weak brands.

QoS-Driven Adaptive Resource Allocation for Mobile Wireless Communications and Networks. (December 2006) Jia Tang, B.S. Xi'an Jiaotong University, Xi'an, China Chair of Advisory Committee: Dr. Xi Zhang Quality-of-service (QoS) guarantees will play a critically important role in future mobile wireless networks. In this dissertation, we study a set of QoS-driven resource allocation problems for mobile wireless communications and networks. In the first part of this dissertation, we investigate resource allocation schemes for statistical QoS provisioning. The schemes aim at maximizing the system/network throughput subject to a given queuing delay constraint. To achieve this goal, we integrate the information theory with the concept of effective capacity and develop a unified framework for resource allocation. Applying the above framework, we consider a number of system infrastructures, including single channel, parallel channel, cellular, and cooperative relay systems and networks, respectively. In addition, we also investigate the impact of imperfect channel-state information (CSI) on QoS provisioning. The resource allocation problems can be solved efficiently by the convex optimization approach, where closed-form allocation policies are obtained for different application scenarios. Our analyses reveal an important fact that there exists a fundamental tradeoff between throughput and QoS provisioning. In particular, when the delay constraint becomes loose, the optimal resource allocation policy converges to the water-filling scheme, where ergodic capacity can be achieved. On the other hand, when the QoS constraint gets stringent, the optimal policy converges to the channel inver-


Metal modified metal oxides are promising and economical catalysts for important processes such as CO oxidation and the partial oxidation of methanol. The present work is to investigate, by density functional theory, the electronic and geometric structures of metal (M = Au, Pt, Pd, or Ru) bilayer modified α-Fe2O3(0001) catalysts, focusing on the synergistic effect at the interface between the metal bilayer and α-Fe2O3(0001) support and its connection with its catalytic activity. It is found that the synergistic effect is largely dependent on the localized electron gain, electron transfer from Fe atoms to the dz2 orbitals of the metal bilayer, and interfacial metallic/ionic bonding. Such synergistic effect is most pronounced for α-Fe2O3 catalysts modified with the Pt or Ru bilayer. The Au bilayer modified α-Fe2O3 catalyst is the most stable due to the low structural deformation of α-Fe2O3 support, minimal surface Fe atom spin quenching, and long Au−Fe bonds. The α-Fe2O3 catalyst modified with Ru bilayer di...


A substantial number of patients attending general neurology outpatient clinics have neurologically unexplained symptoms. Psychological and psychiatric factors may be implicated in the genesis and maintenance of many of these symptoms, but the patients are often unwilling either to accept such explanations or to contemplate therapeutic approaches based on them. It is therefore notable to …


Leukoencephalopathy with brain calcifications and cysts (LCC) is neuroradiologically characterized by leukoencephalopathy, intracranial calcification, and cysts. Coats plus syndrome is also characterized by the same neuroradiological findings together with defects in retinal vascular development. Indeed, LCC and Coats plus were originally considered to be the same clinical entity termed cerebroretinal microangiopathy with calcifications and cysts, but evidence suggests that they are genetically distinct. Mutations in CTS telomere maintenance complex component 1 (CTC1) and small nucleolar RNA, C/D box 118 (SNORD118) genes have been found to cause Coats plus and LCC, respectively.

Assuming an unpolarised beam, an unpolarised target and a negligibly small amplitude of the direct ionisation process, the angular distribution of electrons from the decay of autoionising states with an arbitrary ratio between the energy splitting of fine structure levels J, J' and the natural level width Gamma is derived.


The Brownian dynamics method can give insight into the initial stages of the interaction of antiviral drug molecules with the structural components of bacteria or viruses. RAM of conventional personal computer allows calculation of Brownian dynamics of interaction of antiviral drugs with individual coronavirus S protein. However, scaling up this approach for modeling the interaction of antiviral drugs with the whole virion consisting of thousands of proteins and lipids is difficult due to high requirements for computing resources. In the case of the Brownian dynamics method, the main amount of RAM in the calculations is occupied by an array of values of the virion electrostatic potential field. When the system is increased from one S protein to the whole virion, the volume of data increases significantly. The standard protocol for calculating Brownian dynamics uses a three-dimensional grid with a spatial step of 1°A to calculate the electrostatic potential field. In this work, we consider the possibility of increasing the grid spacing parameter for calculating the electrostatic potential field of individual coronavirus S proteins. In this case, the amount of RAM occupied by the electrostatic potential field is reduced, which makes it possible to use personal computers for calculations. We performed Brownian dynamics simulations of interaction of an antiviral photosensitizer molecule with S proteins of three coronaviruses SARS-CoV, MERS-CoV, and SARS-CoV-2, and demonstrated that reduction of detalization of electrostatic potential field does not influence the results of Brownian dynamics much © The Authors 2022.

The proposed algorithm achieves fast convergence without requiring any external piece of equipment like a turntable. The evaluation of the proposed algorithm is done using experimental data.


In "Low Use of Analgesics in Alzheimer's Disease: Possible Mechanisms," Dr. Scherder draws attention to the important issue of assessing pain in elderly patients with Alzheimer's Disease (AD). The literature consistently shows that demented elderly are prescribed less pain medication than nondemented elderly, and this difference cannot simply be accounted for by the higher prevalence of painful conditions in the nondemented elderly population. Scherder focuses on the AD patient's ability to experience and communicate pain, presumably because patients' communication is assumed to influence physicians' prescribing. Important as understanding cognitive and affective dysfunction in AD may be, the reader is left to struggle with a more fundamental question never directly addressed by the author: Is the (relatively) low use of analgesics in elderly AD patients a problem? Scherder makes a convincing case that accurate assessment of pain in elderly persons with AD is a problem. Evidence suggests that both AD-related decrements in the ability to communicate about pain and disturbances in

Abstract This report shows a multi-compartmental lipoma that occupied a vast area of the hand volar compartment, the distal aspect of the Parona's space and infiltrated the dorsal compartment between the IV and V metacarpal bones. The mass was entirely removed through a dorsal approach, minimizing risks of neurovascular and tendinous lesions.


A retarding field analyzer (RFA) was designed and built for use on the HL-2A tokamak to simultaneously measure the ion temperature and plasma flow velocities in the scrape-off layer via a reciprocating probe drive. The probe was built with many off-the-shelf components, making it even more attractive as a diagnostic tool. The probe consisted of two back-to-back RFA analyzers aligned along the toroidal magnetic field lines to measure the downstream and upstream ion temperatures. The true ion temperature was obtained by averaging the two temperatures. RFA measurements on HL-2A have consistently reported ion temperatures higher than electron temperature with ion-to-electron temperature ratios in the range 1–3. The entrance slit plates of the RFA were used as Mach probes for plasma flow measurements, a first among published RFA experiments.


A study on surface modification of extended PTFE (polytetrafluoroethylene) foil after treatment in oxygen and nitrogen plasma is presented. PTFE was exposed to a weakly ionized, highly dissociated RF plasma with a high density of neutral atoms. The gas pressure was 75 Pa and the discharge power was 200 W. The appearance of the functional groups on the sample surface was determined by using high‐resolution XPS. The results showed that oxygen plasma treatment did not cause any noticeable changes in the surface composition, while after nitrogen plasma treatment new functional groups were detected on the surface.

Although often criticised, the CMO banana has demonstrated a degree of effectiveness. It can only be regretted that it was not able to resist the tidal wave of deregulation. The weakest origins fell by the wayside and the European market went to the strongest operators. This is no doubt the trend of history but surely not that of reason. (Resume d'auteur)


This paper demonstrates the viability of in‐situ transmission electron microscopy for studying the deformation mechanisms of polymer nano‐composites. In‐situ straining studies are performed on carbon multiwalled nanotube (MWNT)–polystyrene composite films. The experiments show that load transfer across the nanotube–polystyrene interface is operative well into the plastic deformation regime of the composite film. The MWNTs are observed to bridge cracks propagating through the polystyrene, providing closure stresses across the crack wake. Although some MWNTs fracture by either a sword‐in‐sheath mechanism or transverse shear fracture, most of the MWNTs eventually debond at the MWNT–polymer interface and subsequently pull out of the matrix.


In this revised and enlarged edition of "The Ancient Olympic Games", Judith Swaddling traces their mythological and religious origins and describes the events, the sacred ceremony and the celebrations that were an essential part of the Olympic festival. A large, detailed model based on modern research and excavation reconstructs the site of ancient Olympia, where alongside religious an civic buildings there grew an elaborate sports complex with a stadium for 40,000 spectators, indoor and outdoor training facilities, hot and cold baths, a swimming pool and a racecourse. Later chapters cover the diet and medical treatment of athletes, sponsorship, patronage, propaganda and revivals of the Games. The last additional chapter on the modern Games is written in collaboration with Stewart Binns, an expert in this field who has worked closely with the International Olympic Committee over many years.


Recently, network coding (NC) has been popularly applied to wireless networks in order to improve scarce wireless capacity. In wireless LANs, NC can be applied to packet retransmission in which multiple packets can be equivalently transmitted by a single retransmission trial at base station (BS). In this paper, retransmission based on NC cooperates with IEEE 802.11e EDCA. In EDCA, when network load is high, QoS is significantly degraded even in high priority class. To solve this, existing methods improve backoff control, and decrease packet loss caused by collision. However, backoff control cannot prevent packet loss caused by multipath channel fading. In the proposed cooperation between NC and EDCA, QoS of high priority class is improved from the aspect of efficient loss recovery. Unlike NC method with no QoS control, we encounter transmission scheduling problem among NC packet, single lost packet, and new packet. Moreover, in the constitution of packets encoded into NC packet, priority and traffic load of each priority class should be considered. Therefore, we propose how to determine the packet to be transmitted at next transmission opportunity in BS and how to constitute NC packets encoded by adequate set of lost packets. Finally, we show the effectiveness of the proposed method by extensive computer simulation.


The Batak' tribe is famous for its customs that are thick with a wealth of life philosophies. Batak' people uphold the noble values that become these traditions. One of the philosophies taught for generations by parents to their children is: "Naso matanggak di Hata, naso matahut di bohi". The sentence has the meaning of daring to say right and wrong. The aims of this research are to describe the philosophy of Toba Batak' culture Naso Matanggak Di Bohi, Naso Matahut Di Hata, towards the character education of children as the next generation. The Method used in this research is descriptive with a literature study approach. The Result of this research is the person will dare to appear different and firm with principles. With the philosophy that has been passed down from Batak' ancestors, children as the next generation of the nation can understand the meaning implied in it and learn a good lesson. This paper can be a useful contribution for anthropologists as a reference in exploring and understanding the philosophy of Toba Batak' culture in character education for organization, society and socializing with others.


Objective:To study the effectiveness and safety of focused ultrasound in treating cervical erosion.Methods:One hundred and sixty-four cases of patients with different degree of cervical erosion were treated with focused ultrasound therapy and were then followed up for 3 months for recording the curative effects and the complications.Results:Cure rate for 164 cases of cervical erosion patients was 75.61 % and total effective rate was 100.00%.The cure rates were significantly different among patients with different erosiondegrees and pathological types(P0.01).There was less fluid flowing and no cervical stenosis and cervical scabbing was found.Conclusion:The focused ultrasound is obviously effective and safe for cervical erosion treatment,with little side effects,it is specially fit for the cervical erosion treatment in nulliparous women.


REGARDING the etiology of insanity, it is of comparatively recent date that particular attention has been directed toward the effect upon the brain of toxins developed by fermentation and putrefaction in the gastrointestinal tract,—faulty metabolism,—and from the poisons in the blood developing from acute infections. According to Peterson "these toxin producing bacteria may be the chief agents whose influence acts upon the cortical cells and nerve fibers of the brain." It is not strange that the blood charged with these toxins should carry agents to the brain, which cause a disturbance of its functions, as we know the blood is the source of all the brain's nutrition and the channel for exit of its waste material. In brain disorders, even without any history having been given of disturbed digestion, on investigation we find evidences of extensive digestive and fermentative changes shown by urinary analysis ; that is, diminished or increased specific gravity, abnormal color, a lack of proper ratio between the specific gravity and the amount of urea eliminated; the presence of indican, zantnins, urates, phosphates, oxalates, and other products. Wagner, in the Klinische Wochenschrift, February, 1903, reports several mental cases in which indican and acetonuria were in excess, and that some of these cases, characterised by severe depression left


This paper presents a literature review about the privacy of information in the cloud computing systems. A simple click after a cloud computing subscription can risk privacy of information. It is advised that the organization develops a cloud computing agreement with the cloud services provider, and with possible third parties. A list of theoretical principles is given to create cloud computing agreements, which must be based primarily on trust. The main contribution of this paper is to exhibit, based on an exhaustive theoretical review, a model for negotiation and agreement between the organization and the cloud computing services provider to comply with privacy of information in the cloud computing environment.


Multiple sclerosis (MS), an inflammatory, demyelinating disease of central nervous system, is the most common cause of neurological disability in young females. MS occurs in India but is comparatively very less as compared to the West. Due to its rarity, obstetricians do not encounter pregnancies with MS in India often. We report a case of a 21-year-old, primigravida who presented to us at 9 weeks of pregnancy. She was a diagnosed case of MS for 4 years. Later in pregnancy, she had walking and gait difficulty. No change in drug dosage was required, and patient had a static course of disease during pregnancy. The patient had an emergency cesarean section. Pregnancy in women with MS is not considered high risk anymore; however, there are some challenges such as managing disability and modifying ongoing therapy. Multi-disciplinary approach is the mainstay of management. Due to severe disability of routine activities such as walking, nursing herself and the baby, pregnancy with MS poses big management challenge. Social issues should be taken care of prior to conception in Indian perspective.


African governments are trying to make family planning acceptable and available to people in communities. Community-based health care has been accepted widely as a good way to reach many people. It brings family close to home and makes services available where needed. Within the last 19 years over 90 community-based delivery (CBD) programs have been started in at least 57 countries. In Nigeria the Fertility Research Unit (FRU) of the University College Hospital (UCH) collaborated with Columbia Universitys Center for Population and Family Health with the support of the US Agency for International Development to test and develop an effective safe low-cost and broadly replicable CBD model in Oyo State. The model provides door-to-door delivery of basic integrated maternal-child health and family planning services in rural areas. It adapts to cultural social economic and political conditions. The project increased the health services given to the rural people. The FRU also tested an urban market-based low cost approach to the distribution of contraceptives. It built on the knowledge gained from the rural program but tested a social marketing approach. The markets in Ibadan Nigeria are central to community life. Many people can be reached through them. The integrated approach was helpful in the child spacing issue. Both the rural and urban CBD projects have been taken over by the government. A number of developing countries have involved the private sector in the promotion of family planning. Social marketing should be monitored by the government so that people can pay for commodities at subsidized rates. Government support is important in taking away procedural constraints. Involvement of the masses--especially women--is necessary in identifying plans and needs.


Background/Aims: Patients with acute coronary syndromes (ACS) presenting with cardiogenic shock (CS) are at particular risk for death and adverse cardiac events. Impaired effects and absorption of oral P2Y12-receptor inhibitors due to decreased organ hypoperfusion or hypothermia and challenges regarding oral administration contribute to this risk. We report a single center experience regarding the use of intravenous P2Y12-receptor inhibitor cangrelor in patients with CS treated with percutaneous coronary intervention (PCI). Methods: Twelve patients with ACS and CS undergoing PCI, not pretreated with oral P2Y12-receptor inhibitors, were treated with cangrelor. Platelet inhibition was assessed by multiple electrode aggregometry (MEA) before and after PCI, immediately and 2 hours after stopping the cangrelor infusion. Results: Nine patients recovered from their cardiogenic shock, 3 patients died. Platelet reactivity decreased from 65.9 (SD 41.0) U before PCI to 15.8 (SD 10.8) U after PCI, 13.4 (SD 7.7) U at the end of infusion and 33.8 (SD 19.9) 2 hours after stopping the cangrelor infusion. There was no non-responder under cangrelor infusion (MEA < 46 U). Conclusions: Due to its favorable PK/PD profile, cangrelor overcomes problems with reduced absorption and effects of oral P2Y12-receptor inhibitors and should be considered for periprocedural treatment of patients with CS.


Microgrid (MG) consists of distributed generation (DG) units, which supply MG loads via the power network. Droop-based control system has been proposed for power sharing implementation among DG units in MGs. The droop control performance is based on the power network variables, which makes it easy to implement. As the control system at the primary level, the droop controller plays a major role in secure operation of MGs in terms of stability concern. However, the lack of high band-width communication links, low X/R ratio of grid impedance and fast response power converters make the droop-based MGs exposed to instability. In this work, a suitable small signal model is developed to assess the droop control system performance and stability. In the proposed model, droop controllers' interaction through the transmission network is modeled appropriately. The proposed model reveals unstable regions which have not been discovered by the conventional parallel-based small signal models.


The article provides an overview of passenger transportation on local and international routes by the Lithuanian railways. It identifies the reasons due to which passenger transportation has become increasingly loss-making. Also, factors that may encourage a greater number of people to travel by train are disclosed. The development of this sector up to 2030 is reviewed, i.e. a forecast for increasing the number of passengers, a perspective for the development of electric, diesel trains, passenger wagon fleet, and the levels of estimated investments are provided. It was established that after implementation of the measures envisaged, losses in the passenger transportation field could be cut by 2–3 times.


When dealing with multivariate remotely sensed records collected by multiple sensors, an accurate selection of information at the data, feature, or decision level is instrumental in improving the scenes' characterization. This will also enhance the system's efficiency and provide more details on modeling the physical phenomena occurring on the Earth's surface. In this article, we introduce a flexible and efficient method based on graph Laplacians for information selection at different levels of data fusion. The proposed approach combines data structure and information content to address the limitations of existing graph-Laplacian-based methods in dealing with heterogeneous datasets. Moreover, it adapts the selection to each homogenous area of the considered images according to their underlying properties. Experimental tests carried out on several multivariate remote sensing datasets show the consistency of the proposed approach.

In purchase behavior research, the personal dispositions of consumers can play a decisive role. This becomes relevant especially in very narrow target groups when socio-demographic constraints are very similar. In the present study, three types of continuity and change in the Big Five personality traits are investigated. While the Big Five personality traits have been extensively studied at the population level over the last decades, there is very little research at the individual level. This study is intended to fill the gap by investigating individual change and ipsative stability using representative panel data. Across four assessments, separated by four years, of the German Socio-Economic Panel (SOEP) from 2005 to 2017, a total of 58,502 participants (ages 16–103, 53% female) completed a 16-item personality short test. An exploratory structural equation analysis revealed very good model fit over age in all four observations. Individual change of a trait is examined by Asendorpf's IS indicator while ipsative stability is measured by the double-entry intra-class correlation coefficient. The results showed that in both domains, stability showed an inverse u-shape with a peak between the ages of 40 and 50.


This article looks at the role of the main opposition party in Ethiopia, Kinijit, during the parliamentary elections of 2005. It shows that the election was unique in that it galvanized the people of Ethiopia to come out and vote en masse. Kinijit was mainly instrumental in mobilizing the people and provided hope for a political change towards democracy. They saw in Kinijit the capacity to lead the country as opposed to the ruling party, trusted it fully and were determined to follow its leadership. The voter turn-out was the highest in the history of the country. Kinijit won the elections but the ruling party rigged the results and declared itself the winner. Controversy arose and dragged on for months. Kinijit then resorted to a protest movement in the form of civil disobedience. The government took this as 'unconstitutional and as preparation for armed rebellion' and began a clamp-down. The entire leadership of Kinijit was imprisoned, and some 400 people were massacred as they demonstrated. Close to 17,000 others were thrown in jail and labor camps. This article examines the flaws in Kinijit's decision to resort to civil disobedience, looks at the consequences of the election for the process of democratization and at what that means in the fight against poverty and under-development. It singles out Kinijit's structural problems, such as insufficient institutional preparedness and lack of organizational structure in 2005, and suggests the strategic political course it should have taken.


A fully monolithic GaAs-94 GHz downconverter consisting of a single balanced diode mixer and a two-stage IF amplifier has been fabricated in a MESFET technology on a single chip. A conversion gain of 14.5 dB combined with a double-sideband noise figure of 6.5 dB has been achieved at 94 GHz. The reported results have been obtained in a one-pass design and show the validity of the design method, using technology based Schottky diode equivalent circuit and harmonic balanced analysis, and they also prove the maturity of the technology for millimeter-wave applications.<<ETX>>

The girellid fish Girella leonina (Richardson) and the holocentrid Myripristis murdjan (Forsskål) are reported for the first time for the Hawaiian Islands from underwater photographs taken at Midway Atoll. Both species can be positively identified by the photographs.


Problem statement: The ability of a blast cyst to hatch, or escape, f rom the Zona Pellucida (ZP) that surrounds and protects the embryo during its first few days of development is one of many critical events that must occur for successful repr oduction. Implantation of the embryo in the uterine lining is impossible unless hatching occurs. Hard o r thick ZP will therefore impaire the implantation process and reduce the pregnancy rate. Approach: Retrospective analysis of patients' records who ha d ICSI cycles comparing pregnancy rate for women with and without assisted hatching between Jan and Dec 2010, this was to evaluate the overall effect o f AH on pregnancy rates in younger women (less than 37 years old) undergoing ICSI cycles at Mustasharak medical center, ABHA, Saudi Arabia. The studied population was divided into four different subgroup s according to age and the differences in clinical pregnancy rate among the assisted hatching group and control group were calculated. Results: Clinical pregnancy rate was found to be significantly higher statistically in young women who underwent laser assisted hatching after ICSI. Conclusion: Laser assisted hatching has a positive impact on th e clinical pregnancy rate following ICSI in young age group.


This thesis try to search the proportion character existing in the wall surfaces by examining the proportion relations appearing
in the windows and doors of the traditional residence architecture, that is the opening, with numerical data. And the results of
the analysis on this study are as follows.
1) The Shaping Principles by the Make-up Elements
. Shaping Principles by Embellishment Materials : The types of the make-up elements are varied according to the functions
of the respective rooms.
. Shaping Principles by the Walls and Doors : In the case of the facade, visual features seems to have been considered
much, whereas the rear side has the feature of being relatively free compared to the facade.
2) The Shaping Principles by the proportion relations of the Walls
. One-dimensional proportion : In both horizontal and vertical proportions, the proportion relation between Woman's quaters
bedroom to the Hall the kitchen to the Hall have respectively different system, and it is thought to be the shaping principle
following a hierarchy
. Two-dimensional proportion : The shape of 1 and ∇2 grid is found between the walls and the opening. In the elevation of
the building, there seems to be the proportion relation that our ancestors preferred. And such kind of proportion relation is
different from the existing western proportion relations like root;golden;rectangular proportion, it can be thought to be the very
Korean proportion system existing as the formative standard in our traditional architecture.


Sharing Transmission Opportunity period (TXOP) technique is recently defined by IEEE 802.11ac to allow simultaneous downlink transmissions. In this paper, we focus on the basis of this technique and the behavior of the access point (AP) to manage the multi-user access. We discuss the different steps required to allow simultaneous downlink transmissions. Based on simulation results, we prove that TXOP sharing technique has a significant positive impact on delay performance of different access categories (ACs).


This paper analyzes a communication network facing users with a continuous distribution of delay cost per unit time. Priority queueing is often used as a way to provide differential services for users with different delay sensitivities. Delay is a key dimension of network service quality, so priority is a valuable resource which is limited and should to be optimally allocated. We investigate the allocation of priority in queues via a simple bidding mechanism. In our mechanism, arriving users can decide not to enter the network at all or submit an announced delay sensitive value. User entering the network obtains priority over all users who make lower bids, and is charged by a payment function which is designed following an exclusion compensation principle. The payment function is proved to be incentive compatible, so the equilibrium bidding behavior leads to the implementation of "cμ-rule". Social warfare or revenue maximizing by appropriately setting the reserve payment is also analyzed.


Most of the human infections start with colonization of the nakel parts of a body skin and mucosa of cavities connectting with an environment. The vagina mucosa is an ecological niche where there are constantly many different kinds of bacteria, viruses, fungi both in practically healthy people, and in patients. In the review it is shown morfo-functional features of vaginal epithelial cells in women and barrier function of vagina normal microflora capable to prevent an exuberant multiplying of exogenic microorganisms and invasion them in vagina wall mucosa.


Antibiotic extraction from solid matrices is generally complicated unlike aqueous phases. Consequently, increasing the extraction efficiency of antibiotics from solid matrices has received a great concern. Therefore, the main objective of this study was to determine three macrolide antibiotics; tylosin (TYL), spiramycin (SPIR), and erythromycin (ERY) in buffaloes' meat using the recommended method of thin-layer chromatography-bioautography (TLC-B) after some modifications. Antibiotics were extracted by 0.2% metaphosphoric acid-methanol (6:4, 7p/7p), and then the extracts were cleaned up using an Oasis HLB cartridges (200 mg). The recovery ratios at 0.5, 1, and 2 maximum residue limits (MRLs) with high precision were 84.19–92.22%, 83.09–89.42%, and 84.89–90.28%, respectively. The detection limits were 12, 45, and 2 ng g−1 for TYL, SPIR, and ERY, respectively. Forty-five samples of Egyptian buffaloes' meat were analyzed using the adapted method. Only 9 and 5 samples out of the 45 samples were positive for TYL and ERY, respectively, with mean concentrations of 42.59 and 31.21 (ng g−1) which were lower than the permitted MRLs recommended by the European community.
