Submitted for the DAMOP09 Meeting of The American Physical Society Quantum Eraser for Improved Spin Squeezing in a Double-Pass Optical-Feedback Geometry COLLIN TRAIL, IVAN DEUTSCH, University of New Mexico — Squeezed collective atomic spin states can be generated using the Faraday effect, by passing light through an atomic sample twice, imprinting the spin component along the direction of the propagation of light on to the light on the first pass, and rotating the atoms proportionally to this spin component on the second pass, thus creating an effective nonlinearity (M. Takeuchi et al., 2005, Phys. Rev. Lett. 94, 023003). The squeezing produced is reduced by loss of light still entangled to the atoms. We show how this scheme can be improved by a quantum eraser effect, where measuring the light properly reduces it's entanglement to our atomic sample.

The kinetics of uraninite dissolution in water may be summarized by the equation: R = (-d(uran)/dt) = 10/sup 20/./sup 25/ (SS) (RF)/sup -1/ (10/sup -3.38-10.8 NOC/) (a/sub ..sigma..CO/sub 2//) (D.O.) (a/sub H/sup +//) exp (-7045/T) day/sup -1/ where R is the rate of the dissolution reaction, SS is the specific surface area (cm/sup 2/-gm/sup -1/), RF is an organic retardation factor, NOC is the mole fraction of nonuranium cations in the uraninite, D.O. is the dissolved oxygen content of the water (ppM), ..sigma..CO/sub 2/ is the total dissolved carbonate, and T is the absolute temperature. Application of these data may allow better understanding of factors influencing oxidation of uraninite and the resulting mobility of uranium in natural waters.


ney begins in the Dust Bowl era with an analysis of the image of the road (representative of the displacement of the 1930s). Each subsequent chapter centers on a key symbol which conveys the multiple transformations the region has undergone: the village (icon of the lost, communal past); the bridge (specifically Otowi Bridge, which links disparate cultures as well as domesticity and the destructive potential of the atomic bomb); the desert (locus of spiritual quest and postnuclear protest); and the border (both the geopolitical border and the boundary between life and death, where graves open portals between material and spiritual realms). The final chapter moves beyond all physical boundaries into the realm of magical realism. Ultimately, Goodman hopes that "by making us mindful of the present and encouraging us to excavate the many layers of the past, photographic and literary representations of southwestern landscapes can engage us in the challenging process of living with ruins and constructing homelands in a culture that overtly values mobility, growth, and change" (10).


Objective To compare the cytotoxicity of TIL and TDLNL from patients with oral squamous cell carcinoma. Methods TILs were isolated from fresh tumor tissues in 5 OSCC Opatients with metastases and TDLNL were obtained from metastatic lymph nodes of them. Then TIL and TDLNL were cultured in the presence of 1000u/ml rIL 2. The cytotoxicity against autologous tumor cells of TIL and TDLNL were detected comparably using 3H TdR 4 h release mehtod. Results The cytotoxicity against autologous tumor cells of TIL was stronger than that of TDLNL ( P 0.02) cultured for 3 weeks, were 35 percent and 23 percent respectively. When cultured for 4 weeks, the latter became stronger than the former ( P 0.02), were 53 percent and 40 percent respectively. Cultured for 5 weeks, the latter still exhibited significantly higher than the former ( P 0.02). Conclusions TDLNL seems possessed more superiority than TIL as AIT for patients with OSCC.


Cardiovasc Diagn Ther 2020;10(4):912-914 | http://dx.doi.org/10.21037/cdt-20-418 On March 9, the American College of Cardiology (ACC) announced the cancellation of their annual meeting, scheduled to start on March 28 in Chicago, IL, USA, due to concerns regarding coronavirus disease (COVID-19) following rapidly increasing confirmed cases in the United States. Notably, this was the first cancellation of the ACC's Annual Scientific Session in the last 69 years (1). The debate leading up to the formal cancellation among attendees, particularly on social media platforms such as Twitter, was rampant with a wide spectrum of views regarding plans to attend. Interestingly, a number of institutions, both private and academic, formally released work-related travel bans for all non-essential travel through the month and beyond. These events and debate raise the question—in the modern hyper-connected world, what is the potential impact of attending a large scientific conference in the setting of an ongoing pandemic? Let us first consider the Biogen strategic management meeting held in Boston, MA, in late February 2020. The meeting had approximately 175 attendees including both United States and international citizens (2). Following the meeting, multiple attendees developed flu-like symptoms with numerous testing positive for COVID-19. By early March, 70 of 92 confirmed cases of COVID-19 in the state of Massachusetts (or 40% of the meeting attendees) were traced to that meeting (3). In response, Biogen placed all attendees of that meeting in quarantine. What could the ramifications be if a major specialty medical conference, with ~10,000 expected medical delegates, decided to convene their scheduled meeting? Creating inferences based on reported data from China, Italy, Iran, and other regions which have been rampantly afflicted with COVID-19 outbreaks (4,5), we devised a decision analysis tree, as shown in Figure 1. Based on reported mortality rates ranging from 2% to 3% of all patients diagnosed with COVID-19, we estimated a 50% infection rate among exposed individuals and 10% hospitalization rate among infected individuals with 2% rate of medical leave consisting of 4 weeks or greater. Next, we estimated that among the remaining 90% of attendees who were infected with COVID-19, 80% would develop symptoms requiring self-quarantine for a 2-week period while 20% remain asymptomatic and resume clinical duties with appropriate precautions. We created three potential scenarios varying from a conservative 10% exposure rate to a more liberal 50% exposure rate with 50% of these individuals becoming infected. Using a 10% exposure rate, approximately 1,000 attendees would be exposed and 500 attendees would be infected. Of these, an estimated 50 attendees would be hospitalized and 10 would require greater than 4 weeks of medical leave. Of the 450 attendees infected but not hospitalized, 360 would be placed in a 2-week quarantine until no longer contagious. Assuming a 5-day work week, this translates to an estimated loss of 4,200 work days, or a cumulative loss of 11.5 work years. Conversely, using a 50% exposure rate, approximately 5,000 attendees would be exposed and 2,500 attendees would become infected of which 250 would develop symptoms warranting hospitalization and 50 would develop severe symptoms resulting in medical leave of greater than 4 weeks. An estimated 1,800 attendees would be selfLetter to the Editor


Abstract. Video stereolization has received much attention in recent years due to the lack of stereoscopic three-dimensional (3-D) contents. Although video stereolization can enrich stereoscopic 3-D contents, it is hard to achieve automatic two-dimensional-to-3-D conversion with less computational cost. We proposed rapid learning-based video stereolization using a graphic processing unit (GPU) acceleration. We first generated an initial depth map based on learning from examples. Then, we refined the depth map using saliency and cross-bilateral filtering to make object boundaries clear. Finally, we performed depth-image-based-rendering to generate stereoscopic 3-D views. To accelerate the computation of video stereolization, we provided a parallelizable hybrid GPU–central processing unit (CPU) solution to be suitable for running on GPU. Experimental results demonstrate that the proposed method is nearly 180 times faster than CPU-based processing and achieves a good performance comparable to the-state-of-the-art ones.


Coating formulation according urea breath test method for detecting Helicobacter pylori infection, comprising at least isotopically labeled C defined as the ratio of the core composition of urea, an excipient and a lubricant, to 100 parts by weight of the composition of the core, the core composition was coated to a coating weight of 0.1 to 10 parts by agent. In this formulation, eliminating the risk of organ resides in the addition of the stomach, e.g. urease producing bacteria on the inside of the mouth and throat, Helicobacter pylori infection can be diagnosed, without the false positive tests, and with a reasonable rapidity.


The paper deals with a novel technique to identify the artifact shape and reduce residual threat during its removal. The method is based on the stimulus artifact reconstruction by using the high resolution Matrix Pencil method. The proposed technique has proved to be efficient in eliminating the stimulus artifact from signals which were recorded on a rat's sciatic nerve.

The Allotment of a set of integers to vertices and edges of a graph satisfying certain conditions termed as labelling of a graph. It was introduced in the late 1960s by (5). The concept of magic labelling which is one of the many labellings itself has a variety. By fixing some natural number (here some atomic numbers) to the edges of F26A graph, it is proved to be a magic graph.


Most of metal amorphous alloys used in practical applications are obtained in ribbons form that does not exceed a thickness of 60μm. Obtaining specimens for mechanical tensile tests is very difficult due to the shape and size of these products. In this paper presents the behaviour at short-term static stress of two nickel based amorphous alloys, obtained in ribbons form. Both metal amorphous alloys were subjected to tensile and micro-hardness tests. For tensile testing were used samples with calibration portion, processed by water jet cutting method. In order to fix the samples in the machine jaws, a proper device was realized in this purpose. For the microhardness test, the samples were cut, then mounted in polymer rings and fixed with synthetic resin. The analysis of fracture surface resulted in tensile test and the surface processed by water jet cutting method was made by scanning electron microscopy.


This paper proposes a design and implementation approach of smart farming system using connected-agronomics technique for fig farm application. Nowadays, fig plants having a rapid growth in the current market demand due to its rich in natural health benefiting nutrients, antioxidants and vitamins where some farming systems have been used  in maintaining fig plant's environmental resources to grow without fail. Smart farming is a system applied to provide user with real time information and plan for desired plant such as time intervals for watering systems. There are two major problems on maintaining the fig fruit quality; watering system fail during emergency blackout and a contagious disease known as leaf rust due to external environments. The system implements two microcontrollers, the Arduino Uno & Raspberry Pi along with smartphone Android application. The system performance is evaluated based on the requirement specification, irrigation soil, surrounding temperature and moisture. It is found that all data collected by the sensors are within the optimal range of values, which are 1500 µS/cm to 1599 µS/cm for the EC reading of the fertilizer while 6.0 to 6.5 for the pH value of the soil. This prototype of smart farming was well developed and can be applied to the fig plantation environment.


We analyze the the convergence behavior of block GMRES and characterize the phenomenon of stagnation which is then related to the behavior of the block FOM method. We generalize the block FOM method to generate well-defined approximations in the case that block FOM would normally break down, and these generalized solutions are used in our analysis. This behavior is also related to the principal angles between the column-space of the previous block GMRES residual and the current minimum residual constraint space. At iteration $j$, it is shown that the proper generalization of GMRES stagnation to the block setting relates to the columnspace of the $j$th block Arnoldi vector. Our analysis covers both the cases of normal iterations as well as block Arnoldi breakdown wherein dependent basis vectors are replaced with random ones. Numerical examples are given to illustrate what we have proven, including a small application problem to demonstrate the validity of the analysis in a less pathological case.


Text Extraction is always a challenging problem in the field of research area. In this paper we developed an algorithm that can be used to extract text from images. We have studied texture feature analysis and also successfully retrieve the texture features embedded in an image. We also calculated number of characters in blurred images. Our algorithm is successfully implemented on many images that are collected from ICDAR Dataset 2011, ICDAR 2013, ICDAR 2003 and some images are collected from newspapers, and digital camera. We used different methods for texture feature extraction. Our algorithm gives more efficiency and extract texture features as compared with previous studies.

The lung area extraction from 3D chest X-ray CT images is an important function in performing computer diagnosis of lung cancer, etc. using CT images. In the conventional lung area extraction methods, when the lesions contact with the chest wall and mediastinum, there is a problem that defects will occur in the extracted lung area. In this paper, to deal with this problem, we will describe a lung area extraction method using a shape model. Concretely, the contour shape is modeled by using a Bezier surface and is made to fit for the contour surface of the individual input images by deformation manipulation based on the affine transformation and active contour model. Using this model, the aforementioned defects of the lung area due to lesions contacting with the wall should be corrected satisfactorily. In the experiments, we show, by applying the proposed technique to 3D chest X-ray CT images, that the lung area can be extracted satisfactorily in cases in which the aforementioned lesions exist. © 2003 Wiley Periodicals, Inc.

Ribs have crucial functions in the human body, most importantly provide protection to the vital inner organs such as heart and lungs. Yet the rib fractures are the most common bone fractures in blunt force accidents. Therefore, understanding more about the impact responses of the ribs is necessary. This study analyses the impact responses of the first and third ribs using the finite element method. A CT image of the thorax was used to obtain the geometric model of the individual ribs. Models with 3D tetrahedral meshes were created and appropriate boundary conditions were imposed. The material of the bone was considered elastic, isotropic and homogenous. The elasto-static analysis was conducted using FEMAS academic software. Distinct variable fields, such as displacement, von Mises equivalent stress, first and third principal stresses, were studied when a constant magnitude load is applied to three different points on the ribs, assuming two distinct directions. Displacement and stress variations along the inner and outer borders of each rib were analysed. Obtained results suggest that a load applied to the lateral region of the bone is the most acute case, showing the highest displacement and stress values. Thus, such findings, indicate the location of a possible fracture (or catastrophic damage) in both rib bones.


To describe the characteristics of pediatric cases of eosinophilic granulomatosis with polyangiitis (EGPA), a systemic necrotizing vasculitis rarely diagnosed in children, retrieved from the French Reference Center for rare pediatric lung diseases and compared with adult cases included in the French Vasculitis Study Group cohort.


One of the most important groups of finds from excavations conducted in Kadero are mace-heads. They were found both in settlement layers of sites and in graves, though the latter is rarer. During re search at these site, three entire mace-heads and thirteen stone fragments were discovered. To date this is the second largest collection of this type found on the Upper Nile. The occurrence of mace heads at sites belong ing to the Neolithic Sudan and to sites of Predynastic cultures of Egypt forces one to reflect on the origin and mutual relations between the Prehis toric cultures of the Sudan and Egypt, as well as possible directions of cultural influence. An analy sis of material originating from Kadero allows for a differentiation of two main types of mace-heads (Cialowicz 1989). The conical type, occurs also at other Neolithic Sudanese sites and is unusually widespread in the I-IIa phase of the Naqada culture (Kaiser 1956; 1957). The second, conical pear-shaped, is found also in the Neolith Sudan site of Shaheinab (Arkell 1953:49-50) though infrequently in Egypt.


A kinetic study of the first step in the reaction of phenol and formaldehyde, the formation of ortho- and para-hydroxymethylphenol, is described.

It is found that when using NaOH or KOH as a catalyst under weakly alkaline conditions (pH = 8.5-10.5) at 30° C, the para-position in the phenolic nucleus is nearly twice as reactive as the ortho-position (the ortho/para ratio being 1.10). Interesting effects are observed in more strongly alkaline media (pH = 10.5-13.5), inter alia a sharp decrease in the ortho/para ratio with increasing value of pH.

When other hydroxides are used, an increasing value of the ortho/para ratio is found with the hydroxides of K, Na, Li, Ba, Sr, Ca and Mg, respectively. Probably chelate formation occurs in the transition state for ortho substitution.


In this paper, we demonstrate, for the first time, how we can pattern grid networks of human hNT astrocytes on parylene-C/SiO2 substrates down to the single cell level. We demonstrate that the functionality of the astrocyte networks by calcium release on the introduction of ATP and show that this is similar to that of a control sample. Thus, we demonstrate that the parylene-C/SiO2 platform is a viable way to investigate glial networks at the single cell level.


In this book, Nadera Shalhoub-Kevorkian, a senior lecturer at the Hebrew University of Jerusalem Faculty of Law's Institute of Criminology and a Palestinian Israeli citizen living in Jerusalem, presents a compelling account of the experiences of Palestinian women living under Israeli occupation and the various types of violence they encounter in their everyday lives, as well as the ways in which women transform their victimisation into agency to resist this violence. Shalhoub-Kevorkian brings a wealth of direct experience to examining her subject. She has spent over 15 years working with women and children facing abuse, mothers of martyrs, female relatives of political prisoners, victims of house demolitions and other types of political violence. Through the voices of these women, the author makes an important contribution to our understanding of the complex and intersecting causes of violence against women, including the silencing of women's voices through discourses of orientalism, colonialism, cultural authenticity, militarism and security, as well as identifying the failure of multiple actors, not least of all the international community to address this violence.


Confounding adjustment plays a key role in designing observational studies such as cross‐sectional studies, case‐control studies, and cohort studies. In this article, we propose a simple method for sample size calculation in observational research in the presence of confounding. The method is motivated by the notion of E‐value, using some bounding factor to quantify the impact of confounders on the effect size. The method can be applied to calculate the needed sample size in observational research when the outcome variable is binary, continuous, or time‐to‐event. The method can be implemented straightforwardly using existing commercial software such as the PASS software. We demonstrate the performance of the proposed method through numerical examples, simulation studies, and a real application, which show that the proposed method is conservative in providing a slightly bigger sample size than what it needs to achieve a given power.


This work deals with the control of a VFD which acts as an intermediary between a three-phase induction motor and the PLC. The induction motor drives a conveyor belt which has three proximity sensor inputs. The first sensor gives the signal for motor to move in the forward direction, the second sensor halts the conveyor for a pre-defined period of time and the third sensor gives the signal for motor to move in the reverse direction. The PLC takes these inputs from the sensors and takes an appropriate action based on the logic developed for the motor control. Finally, the PLC output then becomes the VFD input, which after being reprocessed within the drive brings about the necessary control of the motor with respect to speed and position. In addition, Fuzzy Logic has also been applied to the system so that it can be trained to predict a reasonable output for even those inputs which were not foreseen by the network, therefore making the system flexible and easy to predict the result for various operating conditions. Keywords—VFD, PLC, RS-Logix, Ladder Logic Programming, Fuzzy Logic Controller.


Reliable tracking system is crucial for the development of long range ground-to-ground rocket. Commercial-off-the-shelf systems can be too expensive to implement during research and development phase. With a simple framework, we develop an in-house prototype of data collecting unit (DCU) and a base unit to manage transmitted rocket data. The DCU acts both as a wireless receiver and data storage. It can also transmit data upon request. A base unit sends a command to control DCUs during data retrieval process. Putting DCUs at an appropriate distance, we can effectively receive all transmitted data. It is evident that DCUs located at 2.5 km apart along the flight path have a combined high percentage of reception performance.


This study was performed to gain knowledge on the recognition over the korean foods and fast foods, nutrient knowledge, preference and eating habits among middle school students. This study was conducted over 287 middle school students (155 boys, 132 girls) in Incheon, Korea. The research on the recognition of Korean foods and fast foods, 63.8% of the students recognize the Korean foods as the food with original historic background and cultural characteristics. However 49.5% of the students have recognized the fast food as the promptly served foods with less cooking. Regarding the nutritional knowledge on korean foods and fast foods, Korean food was 7.03 and fast food was 7.00 out of 10 in scale and the male students showed higher rate of recognition but not significantly different. The frequency and preference for the Korean foods were higher with static relevance among middle school students (p<.001). Concerning the level of the nutritional knowledge, students had less knowledge and more frequencies of eating fast foods with statistical significance (p<.05). This study can be used to build the base information for the nutrient education to establish proper eating habits and to make students choose nutritious and balanced foods.


During the past 50 years, the livestock and poultry industries have developed in several areas including nutrition, genetics, engineering, management, and communications to maximizing the efficiency of growth performance and meat yield. Now these industries must focus more attention on how animal agriculture affects the environment and food safety. As in many other industries, the global paradigm is shifting from an emphasis on productive efficiency to one of public security. Nothing demonstrates this paradigm shift more clearly than the issues concerning the use of antibiotic growth promoters. For the past 4 decades, antibiotics have been used in animal agriculture to improve the growth performance and protect animals from the adverse effects of pathogenic and non-pathogenic enteric microorganisms. Now, antibiotics have come under increasing scrutiny because of the potential development of antibiotic-resistant human pathogenic bacteria after long use (Phillips, 1999; Ratcliff, 2000). In response to this "apparent threat", the European Union banned the use of sub-therapeutic levels of antibiotics to prevent disease or promote growth, starting with a ban on avoparcin in 1997 and a ban on virginiamycin, bacitracin, spiromycin, and tylosin in 1999. Antimicrobials scheduled to be banned by 2006 include avilamycin, bambermycin, salinomycin and monensin. In June of 2003, McDonald's Corp. announced that it would prohibit their direct suppliers from using antibiotics that are important in human medicine as growth promoters in food animals after 2004, and they created a purchasing preference for companies that work to minimize antibiotic use. Although banning antibiotic growth promoters may not be scientifically justified, the tide of public opinion is forcing animal agriculture to develop alternatives to antibiotic growth promoters, or at least substantially reduce the amount of antibiotics used to maintain production efficiency and produce safe meat and egg products. Some of these alternatives may include significant changes in husbandry practices or the strategic use of enteric microflora conditioners, including acidifiers, probiotics, enzymes, herbal products, microflora enhancers, and immunomodulators. The objective of this paper is to briefly review the use of antibiotic growth promoters as enteric conditions and discuss the potential of non-pharmaceutical alternatives.


Electric cables in nuclear power plants have to function even after serious events such as a loss-of-coolant accident (LOCA). In most cables, organic polymers that are very sensitive to radiation are used. Nevertheless, much attention was not paid until recently. Under these circumstances, the Japanese government started an extensive research project to examine the degradation behavior of safety-related cables at three different temperatures with three different dose rates. An interim report published recently revealed that some cables would be unable to function after the LOCA test. In this paper, a brief outline of the interim report is described. Categorization of all the causes of malfunctions occurred in electric apparatus in all the Japanese nuclear power plants for recent about 40 years, revealed that there has been only one case of a slight malfunction of cable caused by degradation of polymer insulation, indicating that we donpsilat have to worry so much. It is still very important to establish a proper condition monitoring method in order to secure much higher reliability.


Introduction The effects of natural calamities in human populations are similar to those caused by maj()r wars, Wlwreas the latter occur less frequently today, severe earthquakes, floods, hurriCanes and other cataclysmic events are reported almost every week in the mass media. Factors such as population growth, urbanisation and economic specialisation in many countries result nowadays in disasters-which are becoming increasingly disruptive-ana expensive. The problent:S~of military aid to the civilian community in this country are fairly well understood nnd provision for help is covered by Government circulars in the form of Defence Council Instructions, No. 76 of 1969, No. 147 of 1970, and others. The situation is not so clear in other countries where the major disasters occur. However, in recent years various international bodies have taken a more direct interest in disaster control. Efforts are now directed towards stimulating national governments to deal more effectively with disasters, assisted by international agencies as necessary. Disasters can be classified iQ,to two separate groups, natural and man-made, but there may be some overlap. For instance, the 800 or so earthquakes in Denver, Colorado, which occurred betweel). 1962 and 1966 may have been connected with the injection of contaminated waste into a 12,000 foot-deep well drilled for this purpose. The commonest disasters are:Natural disasters. Earthquakes, serious floods, forest fires and gale force winds (tornadoes, typhoons and hurricanes). Man-made disasters. Explosions, railway accidents, air crashes and pollution incidents (air) (smo~), nuclear (Windscale), gas spillages and oil leaks (Torrey Canyon).

Recently, with the advances in computational speed and availability there has been a growth in the number and resolution of fully 3D hydrodynamical simulations. However, all of these simulations are purely hydrodynamical and there has been little attempt to include the effects of radiative transfer except in a purely phenomenological manner because the computational cost is too large even for modern supercomputers. While there has been an effort to develop 3D Monte Carlo radiative transfer codes, most of these have been for static atmospheres or have employed the Sobolev approximation, which limits their applicability to studying purely geometric effects such as macroscopic mixing. Also the computational requirements of Monte Carlo methods are such that it is difficult to couple with 3D hydrodynamics. Here, we present an algorithm for calculating 1D spherical radiative transfer in the presence of non-monotonic velocity fields in the co-moving frame. Non-monotonic velocity flows will occur in convective, and Raleigh-Taylor unstable flows, in flows with multiple shocks, and in pulsationally unstable stars such as Mira and Cepheids. This is a first step to developing fully 3D radiative transfer than can be coupled with hydrodynamics. We present the computational method and the results of some test calculations.


3 women became pregnant while taking babiturates during oral contraception. The first took Milli-Anovlar for several months and 100 mg phenobarbital belladonna and caffeine for epilopsy. After delivery her gonadotropins measured 40-80 mouse units on Stediril. The 2nd patient used Gynostat for 6 months after having metrorrhagia with stediril and worsening of her asthma with Norquential. She had been taking Apolone (200 mg butobarbital theophylline and prednisolone) regularly and suppositories of 700 mg butobarbital and theophylline for asthmatic crises. The 3rd woman ingested 1 or 2 tables of Optalidon (50 mg butalbital and amydopyrine) for migraine and conceived after several months on Norquential.


This article socializes the concept of research which is being developed in the specialization program in Didactics for sciences with emphasis in Mathematics, offered by Universidad Pontificia Bolivariana. Its aim is systematizing the actionresearch experience with a group of teachers, looking forward the transformation of their pedagogical practice, based on a capacitating model which has its support on the research process. The hypothesis established for the project, is that one of "the teacher as a researcher". In this perspective, this paper is supported on the theories proposed by Stenhouse, about this problematic situation. The project also considers some postulates proposed around education in mathematics, the teacher as a researcher, as well as three orientations about classroom research: first of all qualitative ethnographic research about school situations, as experiences analyzed from the outside of the teaching practice; a second orientation about curriculum, and the third focused on educational actionresearch, centered on the praxis of those teachers who are still working


The utility model provides a second level ceiling which comprises a macromolecule side plate and a first macromolecule corner. The macromolecule side plate is fixed to the top wall, and the first macromolecule corner is fixed to the vertical wall. A second macromolecule corner is arranged at the bottom of the macromolecule side plate. A first aluminum buckling plate is connected between the first macromolecule corner and the second macromolecule corner in a clamped mode, and a second aluminum buckling plate is connected to the top of the macromolecule side plate in a clamped mode. The second level ceiling has the advantages of being convenient to install, stable in structure, reasonable in design, simple in structure, easy and convenient to manufacture and the like.


We propose a Key Graph-based context sharing method in mobile environment. With the recent advancement of mobile sensors, a variety of mobile applications become vehicles for improving our lives. Context sharing system which shares the user behaviors, emotion, and location is one of the promising fields for the social network service. It is a difficult problem to determine whether a user will share the personal information or not. In typical social network models, users are grouped in communities, and nodes of the same community have strong social links between each other. However, some nodes also have social links outside their "home" community. They have social relationships with users of different groups. Most systems concentrate on generating internal "home" community regardless of outside social relation. In this paper, we classify the personal information into two types. First type is the information to be shared with "home" community only. Second type is the information to be shared with as many people as possible. We utilize Key Graph algorithm to select a home community for sharing the personal contexts. Key Graph extracts two types of people who have strong social relationships in a community and have social links with many different communities. In order to show the feasibility of the proposed method, we conduct experiments to extract the user communities from Bluetooth data and implement a real-time context sharing application.


This paper put forward some new ideas and methods on the teaching reform of computer basic courses by analyzing the importance,classified teaching and present situation of the teaching for comput- er basic courses in colleges and universities.


Glomerular AL (light chain-related) amyloidosis is an important complication of plasma cell dyscrasias. It results in destruction of the native mesangial matrix, which is eventually totally replaced by amyloid fibrils. The only treatment available at the present time is to control or abolish the neoplastic plasma cell process responsible for the production of glomerulopathic light chains, the precursor proteins involved in amyloid formation, to allow for the mesangium to heal itself. In most cases, the patients eventually end up in renal failure requiring dialysis or renal transplantation. While the mechanisms involved in the mesangial damage that occurs have been elucidated but the mesangial repair process is poorly understood. How to restore homeostasis to the injured mesangium remains an unresolved issue. Introduction: In AL-amyloidosis, mesangial cells (MCs) are injured by glomerulopathic light chains (GLCs) resulting in MC apoptosis, and the mesangial matrix is destroyed as a result of activation of metalloproteinases by amyloid and inhibition of transforming growth factor-b, which normally controls matrix repair by stimulating production of matrix proteins by MCs [1,2]. Mesangial homeostasis is a well-regulated process that maintains the glomerulus functioning properly. Bone marrow has been declared a reservoir of MCs available for mesangial remodeling [3]. Plasticity represents an important attribute of MCs that allows them to undergo phenotypic transformation when needed [4] and to change their function accordingly, thus participating effectively in mesangial repair. The mesangium has capabilities of restoring itself when the injury is not major employing mechanisms similar to those used for mesangial turnover/homeostasis. The plasticity of MCs is a key to repair minor injuries to the mesangium. One of the challenges is that MCs often disappear in severely injured mesangia. Providing exogenous cells to fulfill the role of MCs and participate in mesangial healing then becomes an important matter. The process of recruitment of cells from extrarenal sites remains poorly understood. Mesenchymal stem cells (MSCs) may play an additive important role in repair processes, especially in situations where the reservoir of existing MCs has been depleted. It has been shown that bone marrow stem cells contribute to kidney healing [5] and that bone marrow transplantation can attenuate murine IgA nephropathy [6]. Also, transplanted MSCs accelerate glomerular healing in experimental glomerulonephritis [7]. The endogeous body sources for stem cells appear to be predominantly a pool of such cells in the kidney and the bone marrow [5,8]. MSCs are a minority of the cells found in the bone marrow; they play an important role in nourishing other bone marrow cellular elements. Much of the beneficial effects of bone marrow cells in the process of glomerular healing are a paracrine effect, as shown in the anti-Thy1.1-mediated model of antibodymediated mesangiolysis [7,9]. In some instances, however, the endogenous pool of MSCs available for glomerular repair is not enough and progressive renal damage occurs. The present work carefully scrutinizes the process of mesangial injury by following the sequential steps that take place and explore the role that the delivery of mesenchymal cells may play in healing the damaged mesangium using an innovative six-dimensional system with living MCs in culture, which allows simultaneous monitoring of different sites capturing images at regular time intervals to better understand the processes involved. Materials and methods: To determine whether MSCs can repair the mesangial damage produced by GLCs and replace damaged MCs, a platform was designed using a 6-D live-cell model to monitor with sequential photos/movies at specified intervals the events taking place. Rat MCs were cultured on Matrigel-loaded glass bottomed multi-well plates with 10% FBS/RPMI 1640 until confluence. MCs were then made quiescent by incubating them with 0.5% FBS/RPMI for 48 hours and then treated with AL-amyloidogenic (Am) light chain (LC)s (10 mg/ml) purified from the urine of patients with renal biopsy proven AL-Am. Controls used tubulopathic light chains from patients with light chain (so-called 'myeloma') cast nephropathy. RMSCs were then stained with PKH-2 fluorescence (green) or with Lysotracker Texas Red (red) and placed 96 hours later into the wells of GLCs treated MCs for 2 weeks. To identify apoptotic MCs, a real time apoptosis detection kit for caspases 3 and 7 was used. Multiple different sites (wells) were carefully monitored simultaneously with sequential photos and movies for 21 days. Results and discussion: MCs incubated with ALAm LCs engaged in the production of amyloid. MSCs cleaned up apoptotic MCs (Figure 1A,B, and C) and eventually replaced injured cells becoming the majority of the cell mass (Figure 1B). The amount of amyloid decreased proportionally to the number of MSCs replacing the original damaged MCs. The damaged mesangial matrix (Figure 2A) was disposed of and new matrix was laid down by the exogenous MSCs. The new matrix recapitulated the 29

Abstract : The monograph examines the friendly information system portion of the battlefield superiority dilemma. It focuses on a very specific portion of operational campaign design: the Big Blue Arrow, a metaphor for decisive operations requiring the movement of forces to achieve objectives. Since future forces expect information superiority, the monograph seeks to determine whether future transformation forces can apply the lessons of history to better focus information support during operational maneuver. The analysis uses a conceptual model of bases and lines of information based on the writings of Jomini and early Signal Corps doctrine. The study reviews the impact of the telegraph, radio, and computer on operational maneuver from the Civil War to modern conflicts such as Operation Desert Storm and Operation Uphold Democracy. The analysis focuses on fundamental characteristics of responsiveness, mobility, survivability, and sustainability of information systems during movement. The monograph concludes that future forces must plan lines of information to focus support where most needed. Without discipline, military information networks tend to overload weak links at the expense of important information. Although satellite communications and digital computer networks provide great capabilities for transformation forces, fundamental constraints still exist in line-of-sight radio propagation, communications channel capacity, and network congestion.


The primary objective of the presentation is to identify a set of experiments to activate the lunar dust and monitor the mode of deactivation process using various analytical methods. To satisfy the objective, a large set of experiments will be carried out using lunar dust stimulant (JSC-1a-vf obtained from Dr. V. Carter from University of Texas at Dallas) to optimize the methodology. After refining the methodology to carry out the experiments using the simulant, real lunar dust will be used to obtain the necessary results. The secondary objective of the presentation is to identify a set of experiments to assess the potential toxicity of the dust using cellular systems. One of the cell lines that we identified is WI-38 human lung cell line.


Mitigating pathological synchrony of neurons in basal ganglia networks was considered as one of the potential mechanisms of deep brain stimulation (DBS) in treating Parkinson's disease. Motivated by reducing the energy of external stimuli, optimal control strategies are presented to regulate DBS waveform so as to mitigate synchronous oscillations of neural networks with fewer energy expenditure. In this paper, the adaptive optimal control of DBS based on reinforcement learning (RL) is designed to desynchronizing phase models of neural populations in the presence of noise. Numerical simulations show the effectiveness of the proposed method. Moreover, the influence of noise intensity on the control performance of the controller is analyzed.

Insights provided in this study may contribute to the development of new alternative biomarkers and development of new therapeutic approaches in IBD.


There are obvious difference between the evaluation modes of power quality and the judgment of their advantage or disadvantage in the viewpoint of power consumers and experts.Considering consumer demand and expert knowledge,a new method to comprehensively evaluate power quality is proposed.Firstly,the evaluations on advantages or disadvantages of indices of all monitoring points are described by language evaluation and expert grading respectively;then taking evaluation information as the evidence,the evidence synthesis is performed by Dempster-Shafer theory to determine the evaluation information on each monitoring point from consumers and experts and to determine the weight of individual,the conflict degree is used to calculate the weight of individual by which the weight of each individual is updated,meanwhile the weights of different groups are taken into account;finally the Dempster-Shafer theory is used again to determine the power quality grades of all monitoring points.The proposed method not only can incarnate different requirements of consumers for power quality,but also can reflect experts' knowledge,so it can incarnate the evaluation opinions of the majority.Simulation results verify the effectiveness of the proposed method.


At present, poor insulation and high energy consumption exist in the rural areas construction. Through the energy conservation reconstruction of walls, windows, roof and other parts of the buildings, the living environment of rural housing was greatly improved, and good economic benefit, social benefit and environmental benefit were obtained.


Objective To study the effects of ischemic preconditioning on acute myocardial infarction(AMI).Methods Sixty patients of chest pain that were diagnosed "Q-Wave(ST-elevation) AMI" in six hours were chose.The cases were divided into two groups according to whether or not having previous angina pectoris in forty-eight hours before AMI,then each group had thirty cases.After the thrombolytic therapy,the quantity of creatine kinase,MB creatine kinase,ejection fraction(EF) of left ventricular,and the incidence of left heart failure and ventricular arrhythmia were measured,then the difference of the two groups was observed.Results The peak value of CK,CK-MB and the incidence of left heart failure and ventricular arrhythmia were lower in the group that having previous angina pectoris in forty-eight hours,and the EF value was higher.


Just like Narcissus of the 21st century, we, bewildered and amazed with our reflection like this, we build, create, recreate and represent our identity in the platforms focused on "finding love". In this way, millions of people throwing themselves as in to the waters of Internet, in the search for their better half. Sadly what Orwell did not see in his work "1984", nor Huxley in "A Happy World", was we ourselves would buy our cameras and that we ourselves, we would even pay to be observed. The following text intend to reflect on digital platforms whose purpose is "dating" or finding a partner, and as these are part of a larger accumulation process, where the economic benefits of paying these sites throughout the last years have gone in crescendo. In another hand, it has led to a digitalization of the self and feelings.


Oat and barley seeds have been exposed to both continuous and pulsed glow discharge plasmas in air to investigate the effects on germination and sprout growth. Statistical analysis was used to evaluate the effect of plasma exposure on the percentage generation and length of sprout growth. A stimulating effect of plasma exposure was found together with a strong dependence on whether continuous or pulsed discharges were used.


Accurate and rapid detection of carbapenemases and identification of their types in Enterobacteriaceae are both still major challenges for clinical laboratories in attempting to prevent the intrusion and transmission of carbapenemase‐producing Enterobacteriaceae. This study aimed to evaluate the performance of the MASTDISCS combi Carba plus disc system in identification of different carbapenemase types, including OXA‐48‐type carbapenemase, for which no specific enzyme inhibitors have so far been available. The simple disc system discriminates carbapenemases, including OXA‐48‐types exhibiting low carbapenem minimum inhibitory concentrations, by targeting Enterobacteriaceae isolates with a EUCAST meropenem screening cut‐off of ≥0.25 mg/L.


The impacts of land-use on the fate of airborne metal pollutants in soils are still relatively unknown. Such impacts were examined in this work by a detailed study on the behaviour of 3 major metal pollutants (Zn, Pb, Cd) displaying a different mobility in soils. This work was performed both for surface horizons of a small region affected by industrial airborne metal fallout, and for a paired study site including two agricultural soils under long-term distinct different land use. The first soil was under permanent pasture (PP), the second under conventional arable land (CA). Both soils were located at comparable distance form the former emission source and developed under comparable pedogenetic conditions. The aim of this work was to i) quantify the proportions of endogenous and exogenous metals in soils, their distribution patterns in the soil horizons and in pedological compartments (microfabrics, aggregates, constituents) and ii) to identify the main mechanisms of metal migration and incorporation in soils. For this, detailed analyses of total concentrations of org. C, Fe, Zn, Pb, La and Cd were carried out, as well as macro- and micromorphological study, kinetic EDTA extractions, and Pb-isotopic composition studies. Ranking of soil parameters, characteristic for land use, influencing distributions and mobility of metals in soils was also aimed. Our results revealed that 40 years after cessation of metallurgical activity, the actual distribution patterns of total metal contents in surface horizons did not corroborate the distribution pattern generally predicted by simple logarithmic modelling of atmospheric deposition as a function of the distance to the emission source and dominating wind directions. The Zn, Pb, and Cd contents in the upper 30 cm of soils under different land use differed notably according to soil pH, redox potential, soil texture or biological activity. For instance, in surface horizons of acid forest soils, a loss of about 80% of deposited Zn was found, whereas about 60% of Zn was shown to have migrated out of surface A horizon, ascribed to earthworm bioturbation in permanent grassland soils, compared to "only" 40% for Ap horizons of arable land. The ratio Zn/Pb and Cd/Pb were revealed as useful indicators to distinguish typical 'metal-fate vs land use' areas. At the scale of the soil profile and soil horizons, a century of distinct different agricultural practices led to clear different phenoforms. In particular, different biological activity observed for the PP and CA soils modified biochemical cycling of metals, leading to different incorporation and mobility of metal pollutants. The two soils displayed clear different distribution patterns of exogenous metal stocks, with a marked accumulation in the Ap horizon of the CA soil (53% of Zn, 92% of Pb and Cd) whereas exogenous metals were more deeply incorporated in grassland soils (only 40% of Zn , 73% of Cd and 82% of Pb stocks at a depth <26 cm). Metal incorporation is significant until 80-cm depth in the PP soil. At the scale of soil fractions, in the PP soil, three types of soil fractions were shown to contribute to metal dynamics due to the high biological activity (aggregates of 50-100 μm and 2-20μm, and the <2-μm fraction). In the CA soil, only the 2-20μm and <2μm fractions were found predominantly implicated in metal retention and extractability. The analysis of Pb-isotopic composition performed both on soil samples and EDTA extracts, was a powerful tool for providing detailed insight on the origin and the incorporation dynamics of anthropogenic lead in soils. It gave evidence for incorporation of anthropogenic Pb until 1-m depth in the PP soil and to about 60 cm in the CA soil. This isotopic approach was found perfectly complementary to current chemical analytical approaches used for studying metal fate in soils, by validating data on estimations of exogenous metal contents. It highlighted the necessity for careful considering pedological parameters in order to guarantee representativity of metal polluted soil samples in studies and to authorize a more pertinent assessment of environmental risks based only on total metal concentrations.

The interplay between regular and chaotic motion in nuclei is investigated in the framework of an open quantum mechanical system. The effect of avoided resonance overlapping (trapping) leads to long-lived traps which correspond to the formation of quantum chaos. They are hidden by short-lived states which correspond to the formation of a new order with less degrees of freedom. The quantum chaos in the nuclear system may be investigated by means of rare decays.


Many scholars have written about Amm. XXXI, 16, 9, paragraph in which Ammianus qualifies himself as miles quondam et Graecus. Generally, it is possible to distinguish two interpretations: it could be a biographic reference or an apology due to his presumed incompetence as latin writer. Starting from the comparison between the whole passage, the two prefaces (XV, 1, 1 and XXVI, 1, 1-2) and other chapters, this paper wants to stress the complexity of Ammianus work and his awareness as a literary man, giving particular importance to the adverb quondam.

The nucleation and growth of alumina layers on two different FeCrAl alloys were compared, taking into account the presence of alloying elements and impurities. Moreover, the oxygen pressure effect on the nucleation, formation and transformation of transition aluminas was considered. Using an "in situ" deflection test, it was possible to determine the kinetics of the γ → α alumina transformation. It was found that impurities and oxygen pressure play important roles on the alumina morphology, on the growth mechanism and on the oxide film mechanical resistance. The long-term oxidation resistance is also related to morphological and chemical aspects of the substrate/alumina interface.


Methotrexate, a folic acid antagonist, is classified as a cytotoxic antimetabolite. It has been used for many years in the treatment of various types of cancer and is also used to treat autoimmune disorders such as rheumatoid arthritis and psoriasis. In the treatment of autoimmune conditions, methotrexate is typically given once weekly, but numerous errors involving methotrexate that has been inadvertently prescribed, dispensed, administered, or taken once daily have been reported worldwide. Because of the immunosuppressive properties that make this drug so valuable in the treatment of autoimmune disorders, daily dosing can lead to serious patient harm. Daily administration, even if doses are low, can cause severe adverse effects involving the bone marrow, liver, and other organ systems. Recently, a cluster of cases were reported to ISMP Canada in which methotrexate was taken or administered daily rather than weekly, resulting in serious adverse effects or death. This article includes (with permission) excerpts from a recent issue of the ISMP Canada Safety Bulletin describing inadvertent daily administration of methotrexate, along with case summaries from other publications. This article aims to raise awareness of the consequences of daily instead of weekly dosing of methotrexate, to highlight some of the contributing factors that have led to the improper use of methotrexate, and to suggest strategies to enhance the safety of methotrexate use.


Background: The female breast is one of the most attractiveaesthetic areas in female anatomy. The size, shape, andsymmetry of the breasts can have a dramatic effect on thewomen's well-being, poor self-esteem, altered self-image, andother psychological effects. All surgical techniques was donebased in the presurgical marking. However it is of little valueif symmetry procedure will be done in other breast.Material and Methods: We retrospectively reviewed 41patients admitted to our multi-disciplinary team breast clinicin Ain Shams University Hospital, between July 2015 andSeptember 2019. Patients' age ranged from 14 to 63 years.Congenital and pathological breast asymmetries were includede.g.: Chronic granulomatous mastitis, burns, and tumors ofthe breast (benign and malignant masses). Physiological breastasymmetry were excluded from the study.Patients were operated upon using the modified SOSmarking technique and followed-up for a mean of 13.24months post-operatively (range 3-30 months). All patientswere photographed before and after the surgery. Post-operativephotographs of these patients were examined by five plasticsurgeons (3 men and 2 woman). We compared both breastsusing a 5 point subscale consisting of volume, contour, placementof the breast mound, scar and the inframammary foldand all patients were asked to complete a satisfaction questionnairebased on the Harvard scale.Conclusion: It is a novel marking technique solved thedilemma of changing the pre-operative plane according to theintraoperative judgment and altering the amount of tissue to beexcised or reconstructed in patients suffering from congenitaland pathological breast asymmetry. It is technical easy to learn,reliable with satisfactory aesthetic outcome especial in congenitalasymmetries, with acceptable complication rate.


We have designed and evaluated a radial-flow bioreactor for three-dimensional liver carcinoma cell culture on a new porous coated scaffold. We designed a culture chamber where a radial f low of culture medium was continuously delivered through it. Once this system was established, f low was simulated using flow dynamics software based on numeric methods to solve Navier-Stockes flow equations. Perfusion within cell culture scaffolds was simulated using a f low velocity of 7 mL/min and found that cell culture medium was distributed unhindered in the bioreactor chamber. Afterwards, the bioreactor was built according to the simulated design and was tested with liver carcinoma cells (HepG2) cultured over an L-polylactic acid scaffold whose surface was modified with iodine-doped polypyrrole. The bioreactor was tested under non-flow and in radial f low conditions. Cell density under radial f low conditions was almost double than that under static conditions and both total protein and albumin output was also increased under radial f low conditions.


Abstract Dislocations have a large effect on the electrical properties of germanium. Experiments show that dislocations act as acceptor centres. This paper discusses a simple model (due to W. Shockley) which identifies dislocation acceptors with the dangling unpaired electrons on the edge of the extra atomic plane of a dislocation having some edge component. In n-type germanium the line of acceptors along a dislocation accepts electrons and becomes negatively charged. The electrostatic energy in the resulting space charge region is found and shown to be a dominant factor in determining the occupation of dislocation acceptors. Formulas are given for the temperature variation of the average electron concentration in n-type material that has been lightly deformed by plastic bending. Experiments are suggested to test the theory and determine exactly the energy level of the dislocation acceptors.


822 Background: Docetaxel is one of the most active drugs for breast cancer. Impact of the Docetaxel in the adjuvant setting of breast cancer is being actively studied.

METHODS
We investigated that effect of sequential docetaxel and cyclophospahamide-doxorubicin combination. Patients with four and more positive axillary lymph node (ALN) were included to study. Patients with 1-3 positive ALN and negative endocrine receptors were also accepted to study. Fifty-seven patients who had undergone modified radical mastectomy were treated cyclophosphamide (600 mg/m) and doxorubicin (60 mg/m) combination 4 cycles every 3 weeks and docetaxel (100 mg/m) 4 cycles every 3 weeks sequentially. Median number of positive ALN was 7 (1-25). Percent of 1-3, and 4 or more positive ALN were 17.5%, 82.5% respectively.

RESULTS
Median age was 42 (23-68). Fifty-four patients were treated by adjuvant radiotherapy and 16 patients received endocrine treatment (7 tamoxifen and 9 tamoxifen and goserelin). Relapse was detected in 12 (21%) patients. The most frequently metastatic side was bone. Estimated median progression free survival (PFS) was 40 months (95% CI 36.9-44.9) and overall survival (OS) was 46.4 months (95% CI 43.9-44.9). PFS and OS rate at 24 and 48 months were 84.6%, 68.8% and 95.5%, 83.0%, respectively. There was no difference on survival parameters according to age, primary tumor size, endocrine receptors, grade, and histopathology. Patients with ten or more positive ALN had worst survival than low positive ALN but differences have limited statistical power. Nonhematologic grade 3 and 4 toxicity was not detected in this protocol.

CONCLUSIONS
Cyclophosphamide-doxorubicin combination plus sequentially docetaxel on adjuvant treatment in axillary positive breast cancer may improve to survival. No significant financial relationships to disclose.


For an abelian Hausdorff group G, let G∗ denote the character group endowed with the compact-open topology and let αG : G → G∗∗ denote the canonical homomorphism. We show that the evaluation mapping from G∗ ×G into the torus is continuous if and only if G∗ is locally compact and αG is continuous. If αG is injective and open, then the evaluation mapping is continuous if and only if G is locally compact. Several examples and counterexamples are given. Let G be an abelian Hausdorff group. The characters of G (i.e., the continuous homomorphisms from G into T = {z ∈ C : |z| = 1}) form a group G∗ under pointwise operations. If G∗ is endowed with the compact-open topology then it is an abelian Hausdorff group, called dual group (or character group) of G. (Cf. [8], [5], [1].) Evaluating characters at points of G gives rise to a canonical homomorphism αG : G → G∗∗. The group G is called reflexive if αG is a topological isomorphism. The classical Pontryagin – van Kampen duality theorem states that every locally compact abelian group is reflexive. It was proved by M.F. Smith ([12]; cf. [1], 15.2) that the additive group of every Banach space is reflexive. Kaplan proved ([6]; [1],14.11) that every product of reflexive groups is reflexive. See [1] (and [10]) for further examples and background. We use multiplicative notation and denote the unit element of G by e. The group G∗ is an abelian Hausdorff group. The family of sets P (K, V ) = {χ ∈ G∗ : χ(K) ⊆ V }, where K is a compact subset of G and V 3 1 is an open subset of T, forms an open neighbourhood base at the unit element χ0 of G∗. Taking into consideration that the mappings x 7→ χ(x) and χ 7→ χ(x) are continuous homomorphisms, it is easily seen that the evaluation mapping (χ, x) 7→ χ(x) is continuous if it is continuous at (χ0, e). Noting that χ(x) ∈ V for all (χ, x) ∈ P (K, V )×K, it follows that the evaluation mapping is continuous if G is locally compact. If G is locally compact, then G∗ is locally compact (cf. the Lemma stated below). We employ the following well-known version of the Arzela – Ascoli theorem. It is an obvious consequence of [9],2.2 or [1],1.5; cf. also [8],Thm.9. Lemma. Let V = {exp(it) : |t| < π/2}. If U is a neighbourhood of e, then P (U, V ) has compact closure in G∗.

This paper is intended to give a brief overview on design optimization of micro_cantilever based MEMS binary inverter. This brief includes the design and optimization scheme for reduction of key parameters of inverter. Sensor integration with active electronics is one of the key issues in Sensor system on Chip (SSoC) and this work essentially reduces the need of CMOS-MEMS integration. The integration requires two separate process flows and authors believe that lot of resources can be saved if circuit topologies can also be created via MEMS. The inverter has been designed and optimized in detail with respect to [1]. The analytical and simulated design is converging to similar values and hence the current design which this paper proposes can be significant improvement over other reported design. The operational characteristics of this inverter are best suited for bio-medical, speech and low-frequency operations.


The interactions of a synthetic edible pigment, tartrazine with β-cyclodextrin were studied using fluorospcrophotometry. The optimal conditions including reaction time and acidity were achieved. The thermodynamic parameters were determined by Hildebrand-Benesi equation at 25, 40 and 55 ℃. The result shows that optimal inclusion time is 30 min and pH value is 7. The association molar ratio of β-cyclodextrin to tartrazine is 2∶1. Lower temperature is favorable for inclusion reaction.


Medulloblastoma is the most common solid malignant pediatric brain tumor. These tumors arise in the cerebellum and can be molecularly subdivided into 4 consensus subgroups, one of which is marked by amplification and activation of Sonic hedgehog (Shh) pathway components and downstream targets. This subclass is proposed to arise from the oncogenic transformation of cerebellar granule neuron precursors (CGNPs), whose expansion during post-natal brain development requires activation of the Shh pathway and downstream targets. These tumors often demonstrate similarities with normal cerebellar development at the molecular level, thus allowing us to use primary CGNP cultures as a model system for the Sonic hedgehog (Shh) driven subclass of medulloblastoma. In addition to mitogens driving proliferation in cancer, it has been shown in the past that low levels of intracellular reactive oxygen species (ROS) can contribute to proliferation through, amongst other methods, phosphatase inhibition and subsequent deregulation of key pathways including pathways that collaborate with Shh signaling. To this end we've studied a reported ROS-generating effector of insulin and insulin-like growth factor signaling, NADPH oxidase 4 (Nox4). It is thought that Nox4 is both upregulated by insulin signaling and synergizes with it downstream via ROS-induced sustained phosphorylation of Akt. Our work in CGNPs revealed a marked induction of Nox4 in response to Shh at the mRNA and protein levels as well as an increase in total reactive oxygen species content. Subsequent studies suggest that Nox4 activity is critical to sustaining proliferation of Shh driven CGNPs. Western blots of shRNA knockdowns of Nox4 showed reduction of proliferative marker CyclinD2. The knockdowns also precipitated a drop in phosphorylated Akt perhaps leaving the Shh pathway without the full effects of one of its major signaling partners, the PI3K/Akt pathway.


ABSTRACT In this paper, thermal, economic, and environmental feasibility of a 5 MW solar photovoltaic power system as an alternative to fossil fuel-operated power plant has been studied for 10 different sites in Pakistan. Long-range metrological data have been considered to access the viability of proposed plant through energy production, financial, and emission analysis. The results show that all sites are within the range of profitable values but Quetta is the most feasible site for installation of solar PV plant. The average values of internal rate of return equity, payback period, net present value, benefit–cost ratio, and capacity factor are 21.75%, 10.58 years, 3,704,588 US$, 1.99, 24.13%, respectively for all sites under investigation. Furthermore, a sensitivity analysis shows that government incentives of up to 40% as an initial cost will lower the payback period to 5 years that make the installation of PV power plants more attractive and feasible. The overall results suggest that installing a PV power plant as a replacement of fossil fuel-operated power system would be a profitable decision.


One of the most critical research programs of today's financial knowledge that is at the top of the rejection of the theory of efficient markets is financial behavior theory. This theory is the result of collaboration between financial sciences and social sciences and makes our knowledge of financial markets deeper. Behavioral finance is a new branch of financial knowledge. Behavioral finance at the macro level challenges classical financial theories, particularly capital efficient market theory. Behavioral finance at the micro level shows that behavior of investors in the real world is incompatible with the fundamental assumption of rationality in classical finance, and cognitive and emotional tendencies or bevels of investors that we called them behavioral biases have an important role in economic decisions making. Behavioral finance of paying attention to the fundamental assumptions of theories in the field of financial economics and capital market like as other branches of the sciences in addition to better understanding and comprehending them, makes our utilization more efficient as a guide in practice. One of the most basic assumptions in valuation of securities and financial products in the stock exchanges is that behavior of investors is rational. This means they seek to maximize their interests, and in addition their response or reaction against the opportunities for taking profit and risk of loss is predictable.


The basic and clinic measurements in the initial cardiovascular work-up of the adult asthmatic are reviewed. This is complemented with the physiopathology of the two problems the frequently arise when an asthmatic is evaluated: 1) if asthma could cause a heart disease and 2) if a heart disease may be hidden in a presumed asthma.


This study shows that magic was a key expression of folk religion in Graeco-Roman times. Introducing the preserved documents of antique magic, Peter Busch traces the magicians' social background and analyses how these documents are related to New Testament thought.


The details are briefly described of how limestone fines and pit run limestone aided dust control, added smoothness and decreased maintenance. Four inches of limestone fines were placed on an experimental 1-mile section, and the material was spread, and compacted. To this date 6 years later, the surface has required only occasional blading to maintain its good condition. Additional mileage has since been similarly treated. In addition, pit run material is being dumped on the roadway and then crushed and compacted with a heavy grid roller. With time and traffic the surface becomes smoother and more dense. Eventually it will have the look and feel of the fines section. It has thus been possible to provide a high quality, dust free road surface for a very low construction cost. It is possible to keep these roads in smooth condition with much less maintenance than required by other gravel roads.

Mandates that require social distancing and sheltering-in-place to stop the spread of the coronavirus have worsened an already concerning public health issue for older adults –social isolation and loneliness. Alabama Extension System at Alabama A&M University developed a program focused on helping older adults connect with family and friends. A descriptive study of 37 older adults indicated that their knowledge, ability, and comfort with implementing Zoom sessions increased significantly after completing the program. Findings show the potential use of the Zoom for Seniors program in preventing social isolation or loneliness among older adults.


This work summarizes an outdoor dynamic measurement of ambient radiofrequency (RF) power density in the core areas of Montreal city, which can eventually be exploited for possible battery-free Internet of Things (IoT) sensor network planning. The measurement covers a frequency range of 400–2700 MHz. The power density along major streets, roads, and highways is captured and analyzed, which differs from previous stationary measurements. Results indicate that cellular communication bands (GSM/LTE850 and LTE700) are the best choice for RF energy recycling in downtown (populated) areas. The largest average power levels of GSM/LTE850 and LTE700 bands are −35.50 and −36.95 dBm, respectively. In contrast, in suburban areas where cellular communication signals are generally weak, the digital television band with a peak level of −47.68 dBm presents the largest among all frequency bands. Moreover, one separate measurement at a fixed location is conducted on a typical workday to study the effects of foot traffic on ambient RF power density. Results illustrate that no obvious fluctuations are detected during this daytime measurement. For example, both average power levels of GSM/LTE850 and LTE700 remain at a relatively stable level of −25 dBm throughout the measurement. With the advance of far-field wireless power transfer and backscattering techniques, ambient RF power-enabled battery-free IoT sensors are feasible and will contribute to the planning and implementation of a smarter and greener city.


As men die a new clientele women and youth is emerging for agricultural schemes and extension services." "It is time that extension workers are trained on the specific impact of HIV/AIDS and they advise women farmers on effective labour and income coping strategies" says a study by Chieza Muchopa from the Department of Agricultural Economics at the University of Zimbabwe. These strategies could include changes like the hardy labour-easy and drought tough cassava sweet potatoes and sorghum could displace rainfed maize as a staple subsistence crop. (excerpt)

There are two distinct approaches to modelling the term structure of interestrates. The first is essenciallly to measure the term structure using statistical techniques by appliyng interpolation or curve-fitting methods to construct yields.The second approach is based on models, known as dynamic models, which make explicit assumptions about the evolution of state variables and asset pricing models using either equilibrium or arbitrage arguments. There is no consensus on any particular methodology and the choice between alternative curve modelsis, in part, subjective. Nevertheless, the interpolation or curve-fitting methods have showed good properties and are those used nowadays by the vast majority of central banks.The objective of this article is to present the principal methodologies that have been proposed for the TSIR estimation. A better understanding of the different methodologies and their limitations will provide the researchers with an overview ofthe problematic of estimation of the yield curve and will enable them to choose the best model according to their objectives.


Autonomous vehicles rely on sensors to measure road condition and make driving decisions, and their safety relies heavily on the reliability of these sensors. Out of all obstacle detection sensors, ultrasonic sensors have the largest market share and are expected to be increasingly installed on automobiles. Such sensors discover obstacles by emitting ultrasounds and analyzing their reflections. By exploiting the built-in vulnerabilities of sensors, we designed random spoofing, adaptive spoofing, and jamming attacks on ultrasonic sensors, and we managed to trick a vehicle to stop when it should keep moving, and let it fail to stop when it should. We validate our attacks on stand-alone sensors and moving vehicles, including a Tesla Model S with the "Autopilot" system. The results show that the attacks cause blindness and malfunction of not only sensors but also autonomous vehicles, which can lead to collisions. To enhance the security of ultrasonic sensors and autonomous vehicles, we propose two defense strategies, single-sensor-based physical shift authentication that verifies signals on the physical level, and multiple sensor consistency check that employs multiple sensors to verify signals on the system level. Our experiments on real sensors and MATLAB simulation reveal the validity of both schemes.


ABSTRACT.— We investigated the genetic population structure of the Black-throated Blue Warbler (Dendroica caerulescens), a Nearctic-Neotropic migrant passerine that breeds in cool mixed deciduous-coniferous forests in eastern North America. A cline in plumage color in breeding populations in the central Appalachian Mountains suggests either a contact zone between two formerly allopatric populations or the presence of a strong contemporary selection gradient. Analysis of 333 base pairs of the mitochondrial control region from 287 individuals sampled from 14 populations revealed relatively high haplotype diversity, low nucleotide diversity, and limited but significant phylogeographic structure across the breeding range (analysis of molecular variance [AMOVA], variation among populations = 2.7%; P < 0.01) and between northern and southern population groups (AMOVA, variation among groups = 2.9%; P < 0.01). Genetic differentiation among populations did not conform to an isolation-by-distance model. Nucleotide ...

Axial developments of one-dimensional void fraction, bubble number density, interfacial area concentration, and Sauter mean diameter of adiabatic nitrogen-water bubbly flows in a 9-mm-diameter pipe were measured under a microgravity environment using an image-processing method. The interfacial area transport mechanism was determined based on visual observation. Marked bubble coalescence occurred when fast-moving bubbles near the channel center overtook and swept up slower-moving bubbles in the vicinity of the channel wall (velocity profile entrainment). Negligible bubble breakup was observed because of weak turbulence under tested flow conditions. Axial changes of measured interfacial area concentrations were compared with the interfacial area transport equation considering the bubble expansion and wake entrainment as observed under a normal gravity environment. The velocity profile entrainment effect under microgravity was likely to be comparable to the wake entrainment effect under normal gravity in the tested flow conditions. This apparently led to insignificant differences between measured interfacial area concentrations and those predicted by the interfacial area transport equation with the wake entrainment model under normal gravity. Possible bubble coalescence mechanisms would differ, however, between normal gravity and microgravity conditions.© 2002 ASME

TiO2-K2SiO3 inorganic coatings were prepared and the factors that influenced their properties were described accordingly. The experiments to assess the properties of TiO2-K2SiO3 coatings on silver (Ag has many applications in aerospace technology as solar cell interconnects) for anti-AO effects were carried out and the coatings with and without exposure to AO impingement from ground-simulation were also studied. Fourier transform infrared spectroscopy ( FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), LAMBDA-9 spectrophotometer, and scanning electron microscopy (SEM) were used to characterize the chemical and physical changes of the surfaces of unprotected and protected Ag samples. The results indicate that Ag is susceptible to AO erosion, presents mass loss and surface degraeation. TiO2-K2SiO3 inorganic coatings have excellent properties for anti-AO effects and good stablility for space environment.


Summary One hundred and eighty white boys and girls, ages 9 and 10, were exposed to an adult female who either demonstrated sharing (behavioral example), focused on the positive and negative consequences of sharing with others (induction), or exerted no social influence (control); and were given either 5, 10, or 20 M&M candies to share with 10 other children. Both induction and behavioral example increased sharing, but children shared significantly more with induction. Children's sharing increased with an increase in resources. Overall, girls shared more than boys, but this was only when girls had 20 M&M candies to share.

Purpose: Being in close contact with the patients during the examination and various procedures, the Ophthalmologists are always at the increased risk of contracting the novel corona virus. The aim of the study was to assess the use of personal protective equipment and other safety measures among the Ophthalmologists in the outpatient departments and operation theatres during the COVID-19 pandemic and their compliance with the prescribed standard guidelines in place. As the outbreaks of new SARS-CoV-2 variants is on the rise, meticulous safety measures is the need of the hour to prevent contraction and transmission of the infection especially among Ophthalmologists who are in close contact while treating the patients. A questionnaire based study Methods: was conducted among the 150 practicing Ophthalmologists of selected medical college hospitals in Pondicherry and the results were analyzed. 150 Results: Ophthalmologists participated in the study. The most widely used PPE among Ophthalmologists in OPDs were N95 masks (n=138), slit lamp breath shield (137) and surgical gloves (114). General Ophthalmologists (n=17) were the maximum to be infected by the virus followed by retina specialists (n=5). 94% (n=14) participants were aware of standard guidelines issued by AIOS and AAO about the preferred practices during the COVID-19 pandemic and 40 participants admitted that they were unable to adhere to the guidelines due to various practical difficulties. Conclusion: This study shows that incidence of COVID among Ophthalmologists was significantly higher in those participants who did not use personal protective equipment and protective measures meticulously while handling the patients

Aim: To examine whether secular trends in adiposity and blood lipid profile of Greek children manifested equally among individuals from urban and rural provinces. Methods: Cretan boys (aged 12.1±2.3 y) from urban and rural areas of Crete were recruited in 1982 (n=277 and 251, respectively) and 2002 (n=440 and 180, respectively). Height, weight, and body mass index (BMI), as well as plasma lipid concentrations were measured and compared across cohorts (1982 vs 2002) and regions (urban vs rural) by two‐way analysis of covariance (adjusted for age) with interaction. Results: Temporal changes in height (positive), weight (positive), and BMI (positive) manifested equally in children from urban and rural provinces, as no interaction was detected. Similar results were obtained for triacylglycerol (positive), low‐density lipoprotein cholesterol (LDL‐C, positive) and high‐density lipoprotein cholesterol (negative) concentrations. A significant interaction was observed only for total cholesterol (TC), which increased from 1982 among rural (by 6.2%, p<0.05) but not among urban boys. In all other instances, regional differences in 1982 persisted in 2002. More specifically, children from urban provinces were taller, heavier, and had higher BMI values than those from rural areas, while they also had higher LDL‐C concentrations, whether nowadays or 20 y ago. Regional differences in TC in 1982 were not apparent in 2002.

The relative amounts of Ra-224, Ra-226, and Ra-228 in a number of petroleum brine samples from Oklahoma and northwestern Arkansas have been determined. The highest concentration found was more than one millimicrocurie/liter of brine. Some brines contained radium isotopes characteristic of the thorium series, others contained Ra-226 which is characteristic of the uranium series, while others contained radium from both the thorium and uranium series. The radium isotopes in the brines are not in radioactive equilibrium with their uranium and thorium parents.


The optical‐absorption spectra associated with transitions between the n=1 valence subband and the donor‐impurity band and between the acceptor‐impurity band and the n=1 conduction subband were calculated for GaAs‐Ga1−xAlxAs cylindrical quantum‐well wires of different radii. The distribution of impurities in the wire was assumed to be homogeneous and interaction between the impurities was neglected. The main features in the theoretical spectra were an absorption edge associated with transitions involving impurities at the center of the wire and a peak related to impurities at the edge of the wire. Calculations were performed for both infinite and finite potential barriers, and were compared with previous results in quantum wells of comparable dimensions.

Abstract To develop the potential as kholifah fii al-Ard, the methods used by each country and region are different. In Indonesia the potential development model used is set in the National Education System with tertiary level of education, from the level of kindergarten, elementary school to university as well as the inclusion of diplomas as proof of completing the level of education, as well as in other countries which is certainly adjusted with the character of the real conditions of the people. One implementation of the National Education System is the formation of educational institutions in order to make a conscious and planned effort to create an atmosphere of learning and learning process so that students actively develop their potential to have religious spiritual strength, self-control, personality, intelligence, noble character, and the skills required by themselves, the community, the nation and the state as an implementation of the mandate of the Constitution is to educate the nation's life. In its development, the influence of globalization and industry, as well as the development of science and information technology has a considerable influence on education, including the shifting of the educational paradigm from idealist-humanitis-ethical towards pragmatic-materealist in the midst of society. The method used is qualitative with a literature approach, as a knife analysis analyzes all information, sources, and documentation relating to education.
