The ongoing Corona Virus Disease-2019 (COVID-19) outbreak has already been given a Pandemic status and also continues to be a public health emergency of international concern. The epidemiological analysis and the trends of mortality clearly suggests that even though, the disease is quite common in all age-groups, the disease has manifested in severe forms among elderly and those people who are having pre-existing medical illnesses. It is the need of the hour to ensure that both these high-risk groups are offered additional attention, without subjecting them to isolation or stigmatization, which decreases their overall probability of access to health care services. Further, it is extremely important to strengthen the risk communication mechanism and take appropriate steps for the relay of timely and trustworthy measures to the entire community, with special attention to the two high-risk groups. In conclusion, as the COVID-19 continues to increase in magnitude and geographical distribution, it is our responsibility to take appropriate steps to improve the wellbeing of community, with an additional support to the high-risk population groups.

Zeolite molecular sieves are important catalysts due to their porous structures, which lead to the size-selective transport of chemical products and reactants. One potential application of the size-selective molecular adsorption properties of zeolites is in the purification of hydrofluorocarbons (HFCs), which are replacing ozone-destroying chlorofluorocarbons in a wide range of uses, e.g., as refrigerants. A first step in understanding adsorption of these HFC molecules by zeolites is obtaining accurate measurements of the number of adsorbate molecules per zeolite supercage. Another class of catalysts, solid superacids, is important for chemical reactions such as isomerization of hydrocarbons, conversion of methanol into hydrocarbons, and polymerization of alkenes. For example, ZrO{sub 2} and TiO{sub 2} have been observed to behave as solid superacids when small amounts of sulfate and hydrogen are incorporated on their surfaces. The acidity of these materials can exceed 104 times that of liquid H{sub 2}SO{sub 4}. One explanation for the {open_quotes}superacid{close_quotes} properties of these materials is that hydrogen ions (Bronstead acid sites) bound to surface oxygens are rendered more acidic by electron withdrawal due to nearby sulfate (SO{sub 4}{sup 2-}) groups. There is much 4 current interest in the synthesis and properties of solid super-acids because they may ultimately replacemore » liquid acids such as H{sub 2}SO{sub 4}, HF, and AICl{sub 3} in industrially important syntheses and thereby reduce the waste streams generated. Characterization of solid acids requires measurements of the hydrogen and sulfate concentrations for correlation with the catalytic properties. We have utilized prompt gamma neutron activation analysis to characterize a number of these materials because of its unique ability to quantitatively measure hydrogen concentrations in addition to a number of other elements.« less


The fabrication and characterization of quantum cascade (QC) disk lasers at 5 μm wavelength is reported. The QC scheme yields several advantages for the disk geometry: an inherently transverse magnetic polarization, tailorable wavelength, and unipolar carrier transport. The low loss whispering gallery resonator allows small devices, 17–125 μm in diameter, and low threshold currents (2.85 mA for a 17 μm diameter disk) with a size independent pulsed threshold current density of 1.2 kAcm−2 at 15 K. From the threshold current density the quality factor of the disks is estimated at Q∼3500. The emission spectra show single and multiple whispering gallery modes.


Recommending sustainable products to the target users in a timely manner is the key driver for user purchases in online stores, which serves as the most effective means to engage the users into online purchases. However, most of the existing recommendation algorithms do not take into account the dynamics of recurrent user behaviors in recommendation processes. The two major but least explored challenges in this field are related to how to make the utmost desirable recommendation at the right time, and how to predict the user's next returning time to the service. This paper presents a novel method that combines self-excitation based on the Hawkes process and a collaborative filtering method based on the Temporal Matrix Factorization method to capture not only the temporal recurrent behaviors but also the change of users' interests that occur over time. Experimental results on various real-world datasets reveal that our model significantly performs better than all state-of-the-art methods.


This study concerned the influences of message length on communication errors caused by human. Based on a beverage plant scenario and developed simulator, experiments were conducted to better understand the relation between the number of instructions and the occurrence of communication errors. The results confirmed that the less the number of commands in a message, the less the communication errors but the longer the used time.


The spectrum characteristics of long-period fiber gratings(LPFG) are different from that of short-period fiber gratings.As there is no back reflection,the properties of optical source could not be affected by the transmission spectrum of LPFG.Based on coupling of modes in fiber core and cladding,and thermo-optic effect,the LPFG sensors can be utilized to detect ambient temperature by the shift of resonant wavelength,and show high temperature sensitivity.The fabrication,operating principle and last development of LPFG temperature sensors have been introduced.As the advantages of low insertion losses,possible use of remote temperature sensing,high sensitivity and immunity to electromagnetic interference,the future application of LPFG temperature sensors is prospected.


Food items "tailored" from other than familiar natural sources are being accepted into the American diet at a rapid rate. Many are espe ciall y adaptable to institutional food service. This is particularly true for certain dairy-type products, fruit-flavored drinks, and simulated bacon bits. Meat analogs developed from vege table protein are mainly being utilized as sup plements or extenders in ground meat and as meat substitutes for dietary or religious reasons. The progress made in developing new protein sources holds promise for tomorrow's "hungry planet." Acceptance of such products by Ameri cans, who have relatively plentiful food re sources, provides hope in other parts of the world where people are protein-hungry. Professor Wanderstock based this article on an address he delivered at Stage VI — Exploring Food Systems of the Future, held December 1967 at the School of Hotel Administration, Cor nell University. Professor Wanderstock is widely known for his lectures and writings in many countries. He is co-author (with the late Carl Reitz) of A Guide to the Selection, Combina tion and Cooking of Food, published by Avi Publishing Company in 1965. —Editor


A lens has at least one insert (16, 28), which defines an optical path. For manufacturing the lens, the insert is first bonded to an overmould (36). A polymer (44) is then moulded in a mould (42, 36) formed on one of its faces from the overmould. After moulding, the overmould may be preserved and form part of the lens, if necessary after surface grinding. The overmould may also be separated from the lens; in this case, the lens is machined, removing at least part of the inserts. The lens obtained has an insert in a reproducible position, with an entrance or exit surface inducing no optical distortion.

Perovskite solar cells (PSCs) have attracted great attention in the scientific community in the past few years. Their many advantages including suitable bandgaps, simple fabrication procedures and outstanding charge-transport properties have propelled PSCs as the promising next-generation photovoltaic systems. However, one key problem faced by PSCs is their short lifetimes that has severely limited their potential for commercialization. The photo-active hybrid inorganic-organic perovskite materials in PSCs were found to degrade rapidly in the air under ambient working conditions. Microscopic understanding of the degradation processes is crucial for the development of more robust perovskite materials. However, such understanding has been limited. In this talk, we discuss the ab initio density-functional study of the degradation reactions of perovskites in the presence of oxygen, water vapor and other reactive molecular species generated from photochemical reactions in the air. We identify the possible degradation mechanisms and examine the different factors affecting the degradation processes. This understanding will provide important guide for rational design of robust perovskite materials for photovoltaic applications.


A novel compact microstrip resonator is proposed with its equivalent circuit. Its resonant properties can then be analytically predicted. Finally, a bandpass filter using this resonator is designed, fabricated and measured, providing an excellent verification on its attractive features such as outstanding spurious response and compactness


This paper addresses the syntactic and rhythmic conditions on prosodic restructuring in iGeneration Taiwanese. The iGeneration, who grew up with an iPhone, or a smartphone, in hand, is loosely referred to people born between 1995 and 2005. The speakers of iGeneration Taiwanese tend to parse them into short fragments, which correspond to smaller phonological phrases. The categorical distinction between lexical and functional projections plays a role in phonological phrasing. Rhythmic restrictions then serve to avoid an oversized phonological phrase. In this paper, I posit a series of alignment and rhythm constraints, and offer an analysis through constraint interaction.

In addition, this paper details an example of application of the methodology proposed with the treatment of hypertension.


A high performance motor drive must produce peak torque which is much larger than its continuously rated value. This paper analyzes the capability of two types of permanent magnet motors using N d F e B magnets and shows that an essentially linear relationship between torque and stator current can be achieved up to the order of 6 times rated current without magnet demagnetization. Also, the motors can be designed to withstand terminal short circuits without magnet damage. These properties have been experimentally verified on two laboratory motors.


The influence of bending-torsional coupling on the buckling load of general orthotropic, midplane symmetric and elastic plates has been studied. First this effect has been analysed for the case of infinitely long plate strips, resulting in approximate analytical solutions, which can be presented graphically for the entire range of the elastic constants. These solutions have been obtained with the approximate method as applied by W. Thielemann. To check the validity of these results for design purposes, they have been evaluated in comparison with results for finite length panels as derived with the finite element method. From this comparison the conclusion can be drawn that buckling loads for plates with aspect ratio over 2 or 3, which demonstrate the bending-torsional coupling effect, can be estimated fairly well from the results for the infinitely long plate strip.

Failure of forecasting the 2008 Wenchuan earthquake has been a shake up for Chinese earthquake forecast research. Since 1966, Chinese have been trying to predict earthquakes by empirical method. This method obtained limited success, but has not been able to make break though after hard work of half a century. Many Chinese seismologists believe that earthquake forecast should be c hanged from empirical forecast mainly based on precursors to physical forecast based on understanding of earthquake mechanics. We therefore propose a frame of earthquake numerical forecast system. Earthquakes occur in the lithosphere when tectonic stress increases and exceeds the crustal strength in the dynamic earth. With growing knowledge of the geological structure, thermal state, porous fluid conditions, physical properties of the lithosphere, and in depth understanding of the earthquake mechanics in the poro-elasto-plasto-viscous rock mass cut by active faults. People now have the capacity to perform massive computation to model the evolution of stress field the occurrence of series earthquakes to produce the synthetic earthquake catalog. The synthetic sequence may help us to understand the real regional earthquakes as better data are obtained model parameters, boundary and initial conditions. It is time to start exploring earthquake numerical forecast, although there is a long way to go to be actual practiced. Weather numerical forecast took about half century from idea to reality. Earthquake numerical forecast may take even longer time. Ten years ago, China had issued the National Earthquake Science and Technology Development Program ( 2007– 2020 ), which claimed to start "the earthquake numerical forecast test research". To implement such a program, a route map of numerical earthquake forecast is necessary. We suggest a frame work for such a route map. A single synthetic earthquake


PROBLEM TO BE SOLVED: To provide a luminous device with high reliability of which, an organic luminous element will not easily be deteriorated by oxidization of an electrode with a small amount of oxygen or moisture. SOLUTION: An organic luminous element is completely shielded from the outside by being vacuum compression bonded with a packaging film 105 coated with a DLC film 106 containing Ar (or, a silicon nitride film, an AlN film, or a film expressed by AlNXOY), so that it can prevent infiltration from the outside of matters, moisture or oxygen or the like inducing deterioration of an organic luminous layer.


With the advent of computational intelligence, the analysis of medical data using machine learning techniques benefits accurate classification of different health diseases and disorders. However, disorganization and variability of data make the job difficult. This paper has streamlined an ensemble learning approach for classification of low back pain disorder based on spinal abnormality data of 310 patients with 12 features. To overwhelm the misleading effect of inappropriate attributes, most influential features are identified using evolutionary feature elimination method. Experiments are performed in both way‒ with or without feature filtering. The basic machine learning algorithms used in the work: Logistic regression, Decision Tree, Naive Bayes, and in addition to the Random Forest ensemble learning method. Random Forest classifier, as expected, is recorded to exhibit the best accuracy of 94% over other classifiers.


Coastal wetlands worldwide are threatened by sea level rise, which is expected to affect the growth and survival of wetland vegetation by increasing water level and salinity. While the effects of salinity and inundation on adult vegetation of oligohaline marshes have been widely studied, the species composition of the seed bank and its response to elevated salinity and water level have not been examined. Additionally, the role of disturbances of different intensities in structuring marsh plant communities and possible interactions between disturbance and rising sea level have received little attention. Disturbances in coastal marshes include nonlethal disturbances such as fire and herbivory (which can remove aboveground vegetation but leave rhizomes intact), and lethal disturbances such as wrack deposition, sedimentation, scouring, or fire, or herbivory followed by flooding. I conducted a series of experiments to examine the role of seed banks, disturbance, and sea level rise in structuring the plant communities of oligohaline marshes in coastal Louisiana, USA. I found that seed banks of three oligohaline marsh communities were similar despite differences in the adult vegetation, and that higher salinity or water level reduced the germination of most species. In a field experiment lethal disturbances promoted the establishment of species via seedling recruitment, leading to persistent changes in community composition. Regeneration following less intense nonlethal disturbances, however, was primarily via vegetative growth which quickly restored the pre-disturbance community structure. The effects


We study the positive and negative ionization probabilities P+ and P− of atoms sputtered from C60 at energy Ec. As the atom leaves the target molecule, its atomic level progressively decouples from the target levels; this can be described by means of the Anderson Hamiltonian with time-dependent parameters. In a first part we neglect the repulsion between electrons and study the positive ionization. We present an exact numerical solution of the Schrodinger equation. We obtain for P+(Ec) a power-law dependence with an exponent slightly varying with Ec. This dependence is different from the exponential law given by another commonly used model. In a second part we introduce an intra-atomic repulsion between electrons which allows us to calculate negative ionization probabilities.


Characteristics of instrumentation and control (I and C) system failures, including set-point drift problems, are discussed. Specific topics included in the discussion are: general trends in the occurrence of I and C failures, principal reactor systems affected, variation in I and C failure rate over time and the impact of I and C problems on plant availability. A total of 977 I and C failure events and 640 set-point drift events, reported by LWR licensees, provided the basis for the observations and conclusions presented.

This paper presents a framework for controlling the evolution of complex software systems concurrently developed by teams of software engineers. A general technique for fine-grained revision control of hierarchically structured information, such as programs and documents, is described and evaluated. All levels in the hierarchy are revision controlled, leaves as well as branch nodes. The technique supports sharing of unchanged nodes among revisions, automatic change propagation, and change-oriented representation of differences. Its use in a software development environment is presented, facilitating optimistic check-out of revisions and alternatives, check-in with incremental merge support, visualization of change propagation, and an integrated flexible diff-ing technique providing group awareness for team members.

The performance of data delivery in wireless relay networks (WRNs), such as delay-tolerant networks and device-to-device communications heavily relies on the cooperation of mobile nodes (i.e., users and their carried devices). However, selfish nodes may refuse to relay data to others or share their resources with them due to various reasons, such as resource limitations or social preferences. Meanwhile, misbehaving nodes can launch different types of internal attacks (e.g., blackhole and trust-related attacks) to disrupt the normal operation of the network. Numerous mechanisms have been recently proposed to establish secure and efficient communications in WRNs in the presence of selfish and malicious nodes (referred as non-cooperative WRNs). In this paper, we present an in-depth survey on human-centric communication challenges and solutions in the non-cooperative WRNs that focuses on: 1) an overview of the non-cooperative WRNs and introduction to various types of node selfish and malicious behaviors; 2) the impact analysis of node selfish and malicious behaviors on the performance of data forwarding and distribution; 3) selfish and malicious node detection and defense systems; and 4) incentive mechanisms. Finally, we discuss several open problems and future research challenges.


Abstract. Using a family of mock modular forms constructed by Zagier, we study the coefficients of a mock modular form of weight 3/2 on SL2(Z) modulo primes l ≥ 5. These coefficients are related to the smallest parts function of Andrews. As an application, we reprove a theorem of Garvan regarding the properties of this function modulo l. As another application, we show that congruences modulo l for the smallest parts function are rare in a precise sense.


In this paper we give the proof about the equivalence of the complete Einstein- K■hler metric and the Bergman metric on Cartan-Hartogs domain of the third type. And we obtain the method of getting the equivalence of two metrics.


To predict the quality of the low permeability reservoir of the Member 3 and Member 4 of the Quantou Formation in the Northern Songliao Basin,the diageneses of the clastic rocks were divided into early diagenetic stage A,early diagenetic stage B,middle diagenetic stage A1,middle diagenetic stage A21,middle diagenetic stage A22 and middle diagenetic stage B.The results of the statistical data show that diageneses have apparent controls on the physical property and oil saturation of the reservoirs,and the sand bodies of any sedimentary facies can not produce commercial oil and gas flows in middle diagenetic stage B,and only the porosity of main river channel sand bodies is higher than the porosity cutoff of commercial oil and gas reservoir.The diagenetic stages of the Member 3 and Member 4 of the Quantou Formation in the northern Songliao Basin were predicted using diagenetic numerical modeling technology.The reservoir quality of the Member 3 and Member 4 of the Quantou Formation is the result of integrated effects of sedimentary facies and diageneses.The reservoir types and quality distribution of the Member 4 of the Quantou Formation laterally were predicted by overlap the sedimentary facies map on the diagenetic stage prediction map.The commercial oil and gas well mainly located in the reservoirs of type Ⅲ3,Ⅲ4 and Ⅲ5 in Central Depression of the northern Songliao Basin,where will be the potential exploration area of the Member 4 of the Quantou Formation in the basin.


Echocardiographic left ventricular size and closure time of the mitral valve were measured in 204 consecutive patients having cardiac catheterization and significant coronary artery disease to determine if these measurements could assess the extent of left ventricular dysfunction and predict surgical mortality for those patients treated surgically. Among 30 patients having both an echocardiographically increased left ventricular internal dimension at the end of diastole and a prolonged time of mitral valve closure, left ventriculographic studies showed greater than 40 percent abnormality of wall motion in 24 patients (80 percent), and the resting left ventricular end-diastolic pressure averaged 23 mm Hg. Of the remaining 174 patients, only 13 (7 percent) had greater than 40 percent abnormality of wall motion, and the left ventricular end-diastolic pressure averaged 11 mm Hg. Eighty-six of the 204 patients received surgical therapy. Mortality during hospitalization for those surgical patients with both echocardiographic findings was 67 percent (6/9) compared to 1 percent (1/77) for those without both findings (P


This paper proposes a method to better address the optimization problem of cable forces in cable-stayed bridges, particularly when considering multiple objectives simultaneously. It applies genetic algorithms to optimize cable forces and utilizes Pareto theory for multi-objective optimization. The proposed method is implemented using MATLAB software as the programming platform and ANSYS parameterized modeling. Additionally, an actual bridge is used as a case study to validate the proposed optimization method. By minimizing the main beam bending strain energy and the maximum cable force of the cable as objectives with cable force values as optimization variables, the internal force state of the structure is improved by adjusting the cable forces distribution. The Pareto optimal solution is obtained through optimization calculations, reflecting the minimum main beam bending energy that can be achieved under different cable force safety factors. This solution can guide engineering design.


The total protein level is reduced and the electrophoretic pattern of the serum is changed in trout Salmo trutta L. infected with UDN, as in the Atlantic salmon. However, the changes in the trout are not as characteristic as those in salmon and thus are of very limited use in diagnosis of outbreaks of this disease among trout.

Introduction: Neutropenic enterocolitis is defined as a multifactorial inflammatory process typical of neutropenic patients, characterized by transmural damage mainly at the level of the cecum, although it can affect other areas such as the ascending colon and ileus. Due to the difficulty in the diagnosis and the complications that are presented, a descriptive study of this pathology, its diagnostic methods, management and main associated complications is carried out.
Methods: Between October 2016 and September 2017, a retrospective and descriptive study of patients diagnosed with Acute Lymphoblastic Leukemia (ALL) with relapse or refractoriness of their underlying disease who presented clinically and radiographically compatible conditions with neutropenic enterocolitis was performed. The study was carried out in the pediatric oncology service of the National Oncological Institute "Dr. Juan Tanca Marengo ", Solca Guayaquil.
Results: A total of 21 cases were identified, 17 (80.95%) of which were male. The main symptoms presented were abdominal pain, diarrhea and fever, in the context of neutropenic patients, who had received chemotherapy in the previous days. Abdominal ultrasound was used in all cases together with abdominal tomography performed in 6 patients as a complementary method to the diagnosis. No patient was operated on. All patients were managed conservatively with a favorable evolution.
Conclusion: This pathology should be suspected in any patient who presents symptoms compatible with abdominal pain, associated with fever or diarrhea and who had received chemotherapy in the previous days. The complementary studies necessary for the diagnosis must be requested urgently, and the patient must be managed in an integral manner. Reserving the surgical treatment for patients with an unfavorable evolution.


Flattened anterior chamber or absence of a formed anterior chamber is a complication of cataract surgery generally believed to be associated with a high incidence of aphakic glaucoma. While the incidence of vitreous loss, iris prolapse, and ocular infections has been reduced by refinements in anesthesia, wound closure, and antibiotic therapy, the occurrence of flat chamber still remains a problem. Postoperative flat chamber, with its attendant danger of aphakic glaucoma, has been of great concern to the ophthalmic surgeon. Czermak1in 1897 recognized microscopically the closure of the chamber angle in aphakic glaucoma. A correlation between peripheral anterior synechiae and aphakic glaucoma was noted by Troncoso2in 1934. Kronfeld and Grossman,3McLean,4and, later, Meyer and Sternberg5indicated the relationship of delayed formation of the anterior chamber, peripheral anterior synechiae, and aphakic glaucoma. Sugar6attributed the delayed re-formation of the anterior chamber to poor


During the process of the rectifying by thyristor in the three phase symmetric AC power system the high order harmonic current is produced.It is harmful to the power system not only influencing on the power quality but also resulting in the maloperation of the relay protection or burning out the electrical board of micro computer protection and digital electrometer and other devices in the computer system.It is,nevertheless,possible to filter the high order harmonic voltage by using AC filter equipment reasonably designed.On the basis of description of the harm of harmonic current and the method of restraining the harmonic,this paper presents the theoretical calculation of AC harmonic filter,and also the way of reasonable selection of the AC filter for eliminating the high order harmonic current is discussed as well.

Abstract This article presents the process of building knowledge to inform the process of developing a design application for mid-‐size urban settings. We call such an application Campus Information Modeling – CIM. Four different strategies are exposed, with special interest in a behavioral study regarding users' qualitative evaluation of buildings they inhabit and how such information will be used in the design of the CIM tool. Finally, implications and future research are discussed. Keywords: Campus Information Model; Building knowledge; Behavioral Study; Software Design. Introduction Digital tools such as geographic information systems (GIS) and building information model (BIM) support both, planning and design activities at regional and building levels respectively. However, there is a lack of tools to inform planners, designers, and decision makers when forecasting new facilities and intervening existing ones at scales such as campuses and small neighborhoods. In addition, current GIS and BIM tools offer limited real time evaluation for budgetary and financial simulations, operational costs, and user accommodation. Moreover, to the best of our knowledge GIS and BIM tools does not include among their tools and functions capability to include spatial qualitative data. These three issues can be addressed under one single core question that, we think, is aligned with the main theme this conference possess; How do we build knowledge for design? In order to address such a question we present here our work, currently under development and based on a real case in a large university in the US. The housing department of the university is increasing the number of beds they offer, and at the same time seeking to improve the environment they provide for students. In short, they seek more beds and better buildings. Consequently, the goal of this project is to build an application with capabilities to evaluate in real time different scenarios at campus scale comparing different types of residential buildings. We call this application Campus Information Modeling(C IM). Campus Information Modeling (CIM) converges all sources of spatial, financial, and users' data about buildings, structures, and land into a common information intermediate scale framework. However, before delving deep into CIM model issues, we envision a key question that emerge prior the development of such a tool: What kind of information does such a system need, and which arethe most reliable sources to obtain that data? To address this question we designed a strategy to gather different types of reliable data that may be used for real time evaluation of design options. Thus, four approaches for data acquirement were used in the design of the strategy for capturing data: First, we completea revision of the existing buildings in campus. Second, we review the financial model regarding construction and operation budgets in residential buildings in campus. Third, we dida literature review of current issues in college housing. Fourth, we ran a behavioral study with students living in campus. These four steps providethe set of data that became the inputs to develop themodel of the CIM tool. Using as case study the renovation of residential buildings for undergrad students that will take place during the next academic year we offer here the methodological approach designed to build and embed knowledge on such tool.

The association between the use of oral hormonal contraceptives and venous thromboembolic disease (VTE) was described for the first time at the beginning of the sixties. Starting with the first epidemiological studies at the end of the sixties it has been demonstrated that oral hormonal contraceptives increase the risk of VTE disease. The thrombotic risk due to the use of oral estrogen-progestin contraceptives is related in the first place to the estrogen concentration of the pill as well as to the amount and androgenic effect of the associated progestin. The risk is additionally influenced by special circumstances like the congenital thrombophilic factor of every woman. (excerpt)


12 patients with known allergy to nickel were patch tested with nickel sulphate, nickel chloride, and sodium lauryl sulphate 1, 2, 5 and 10%. 2 parallel series were performed, i.e., one with 24‐h and one with 48‐h application time. Reactions were followed by measurement of transepidermal water loss (TEWL). Allergic reactions showed a normal TEWL after 24‐h application, and after 48 h. only strong reactions resulted in increased TEWL. In contrast, irritant reactions showed increased TEWL in both series, irrespective of the strength of the reaction.


A serial of samples of La0.67Sr0.33-xNaxMnO3 (x=0.05,0.10,0.15,0.20,0.25,0.33) were synthesized by the standard solid-state reaction. The variation in crystal structure and the transport properties of the sample were investigated through FTIR spectrum,Raman spectrum,ρ~T curves and ρ~T fitted curves. Our experiment shows that the variation in band length and band angle of Mn-O-Mn increases with increasing of Na content; the transport mechanism originates from double-exchange interaction; on the low temperature range(TTp),ρ(T) accords with the ρ~T2 relation,and the transport mechanism is the function of single magneton scattering,while on the high temperature range(TTp),all of ρ~T curves are fitted very well by [ρ-Texp(T0/T)]and ρ(T) accords with near-neighbor-hopping model of polaron.


"Among honest people, the equality of the sexes is no longer a contested principle." This confident utterance is found in an open letter to an "unknown, spirited gentleman" published in the issue for January 1682 of the influential French literary magazine Le Mercure Galant and signed by "Madame de Saliez, Viguiere d'Alby." Seven years later, she expressed the same opinion in even stronger terms: "Several of our best writers have thoroughly discussed the equality of the sexes, a principle that is no longer contested in France." The full name of the author of these lines was Antoinette de Salvan de Saliez, a widowed lady of aristocratic standing and a lifelong resident of the small town of Albi in southern France. Her confident language is surely striking for a provincial lady in the heyday of French Classicism, an age that has often been depicted as deeply hostile to all manifestations of female intellectual autonomy. In his study of seventeenth-century feminist literature, Ian MacLean has even claimed that feminist writing "almost ceased" after the beginning of the personal reign of Louis XIV in 1661. Now it can easily be shown that the last statement is untenable and that feminist publishing continued in the 1660s, 1670s, and 1680s. Admittedly, in these decades the French literary scene came to be dominated by figures like Moliere, La Rochefoucauld, and La Bruyere, who, while critical of old-style, boorish misogyny, spoke in extremely sarcastic and dismissive terms about women's aspirations to participate in intellectual


Abstract The differential equations governing the transmission of one-dimensional sound waves in a non-uniform duct carrying a subsonic compressible mean flow have been the subject of a recent debate [1, 2]. Of the two formulations presented, one is considered to be non-acoustical and the other as neglecting the spatial variation of the speed of sound. The present paper shows that both formulations are acoustical and represent valid approximations to correct conditions for isentropic sound propagation in a subsonic low Mach number duct. Each formulation is associated with an "error wave", which is essentially a hydrodynamic wave when the mean flow Mach number is small. Three-port modelling is required, however, to capture this wave when the Mach number of the mean flow is relatively large and a numerical matrizant approach is described which can be used for this purpose.


The problem of guiding a flock of agents using repulsion forces exerted by a smaller number of agents is called the shepherding problem. The objective of this problem is to design shepherd agent methods so that the shepherd agent guides sheep agents to the destination area in a short time. Although various shepherding methods have been proposed, most of these methods assume that the sheep agents have the same dynamics. However, this assumption does not necessarily hold in reality. Therefore, in this paper, we propose two shepherding methods for a flock of sheep agents including variant agents. In the proposed method, the shepherd agent estimates the trajectory of the sheep agents and discriminate the type of agents based on the degree of deviation from the predicted trajectory. Then, the shepherd agent guides sheep agents discriminated to be normal. Numerical simulations showed that the proposed methods can guide more agents than the conventional method. The shepherd agent guided average 84% of normal sheep by the proposed methods while 64% by a conventional method.

ABSTRACT For tissue regeneration or repair, a suitable temporary scaffold needs to be constructed for delivering regenerative cells to damaged or diseased tissue. Scaffold types are currently categorised into 3D monolithic scaffolds, hydrogels, and microcarriers. Among these scaffolds, microcarrier systems offer an attractive method for cell amplification and enhancement of phenotype expression, and they have emerged as powerful injectable carriers to repair and reconstruct irregular defects in tissues and organs. In this article, several important issues related to polymeric porous microcarriers for tissue engineering are reviewed. The properties of porous microcarriers, including surface chemistry, pore structure, typical particle size, and specific density, and the corresponding effects on cell cultures are discussed. The fabrication techniques and biomaterials investigated for porous microcarriers are summarised, and their advantages and disadvantages are outlined. Recent advancements in the application of porous microcarriers, including bone and cartilage tissue engineering, are also presented.


A theoretical study of the dispersion relation of transversely magnetized circular cylinder with metal boundary is discussed. In the present paper we show that the characteristic frequency generally increases with increasing wavenumber. This shows that the dispersion relation gives forward waves. This situation is closely similar to the independent study by Auld and Mehta for the theoretical results on the problem of transversely magnetized rectangular rods.


The paper is a review article on how recent International Relations ("IR") literature perceives the Roman Catholic Church. It attempts to show how the actorness of the Church is being represented on IR literatures written especially at post-Cold War era. The time frame is chosen because attention towards transnationalism and its corresponding actors has only emerged from that period of time, thus enabling scholarly discussion on religious actors. Firstly, this article is going to trace early mention of the Catholicism and IR. Then, it is going to explain how current IR scholars analyse the Church. It is found that majority of current discussions are based upon the underlying assumption that Vatican City State, the Holy See, church network and Catholic NGOs exist as different entities. Next, the article is going to highlight recent developments which attempted to suggest the Church as – perhaps – a multi-layer being, contrary to what is currently believed. Using the logic borrowed from Catholic theology, I am offering a synthesis of the Church as a multifaceted actor, not unlike the unitary state as understood by classical realism. Therefore, this review article can also be seen as a challenge towards the collective understanding, or lack thereof, about one of the oldest surviving global political actors, the Roman Catholic Church.


Alzheimer's disease (AD) is a neurodegenerative disorder characterized by memory deficits and cognitive decline. Major hallmarks that occur during early stages of disease progression include amyloid beta plaque, neurofibrillary tangles, and synaptic loss. The mechanisms that particularly govern synaptic loss, however, remain under investigation. Local, dendritic mRNA translation is critical in maintaining proper synaptic architecture as well as engagement with presynaptic terminals. A master regulator of this process is controlled by mammalian target of rapamycin complex 1 (mTORC1), whose activity has shown to be significantly increased in AD patients as well as respective animal models. Increases in mTORC1 activity have consequently shown to upregulate the translation of various downstream synaptic proteins, one of those being GABAB receptors (Niere, 2016). Metabotropic, GABAB receptors are critical in maintaining slow, sustained inhibition throughout the central nervous system. However, their significance towards synaptic function is understudied in the context of AD.


Introduction: New digital media (e.g. Internet, text messaging and social networking websites 'SNW') have dramatically altered the communication landscape, especially for youth. These communication platforms can be used as a tool for engaging youth in health promotion and risk reduction. The study has done to determine the efficacy of using social networking site as a media to deliver tobacco related health messages. Methods & Material: A webpage named "Smoke Free India" was created on Facebook and was put under 'Sponsored advertisement' for 15 days targeted on Indian population. Short messages regarding smoking and tobacco in the form of text, images, video clips and web links were shared on the page for 30 days. Results: Total 907 users from different cities "Liked" the page, out of that 63.8% were by age of 13 to 17 years. Male gender preponderance was seen for maximum likes in all age groups. Highest uptake occurred for the images followed by text update, video clips, and web links. While use of internet media is considered as challenge in tobacco control policy, the present study favours use of SNM as a communication tool to spread health messages among the internet users.

Spin-valves comprised of Co or NiFe magnetic layers and NiO as the antiferromagnetic pinning layer have been prepared by magnetron sputtering. Their structural, magnetic and magnetotransport properties have been characterized. A dramatic enhancement of the coercivity of the magnetic layer adjacent to NiO is observed due to the onset of a very large uniaxial anisotropy. In addition, depending on the conditions of deposition, the hysteresis loop of the pinned layer can be either centered around zero field or shifted as is usually observed for exchange anisotropy. In the latter case, the field characterizing the shift of the loop decreases much faster with increasing temperature than does the coercive field. These samples have good thermal stability up to 250/spl deg/C. Their response at low fields can be made reversible by applying a static biasing field transverse to the field to be measured. A detailed study of minor MR hysteresis loops has been carried out.

Tube plates of heat exchangers often consist of circular elastic plates into which tubes are secured by welding or swaging. The holes in the plate into which the tubes are fixed are arranged in zones within the outer boundary of the plate to suit the nesting of the tubes.Such tube plates are flexed principally by a hydrostatic pressure differential. In this action they function as many-times multiple-connected elastic plates and exact analysis is greatly complicated by the many internal boundaries.Since such boundaries are normally grouped in the form of zones of regularly arrayed, identical and uniformly pitched holes, the notion of 'equivalent elastic constants' as discussed in a related paper, reference (6), can be used to describe the average behaviour of such drilled zones. The number of significant internal boundaries can thus be reduced to the number of zones corresponding with the number of nests of tubes, usually two or four.The boundaries of the nests usually possess symmetries about the diamete...


M.Manjuri and B. Maheswari Abstract— Theory of domination in graphs introduced by Ore and Berge is an emerging area of research in graph theory today. It has been studied extensively and finds applications to various branches of Science & Technology. Products are often viewed as a convenient language with which one can describe structures, but they are increasingly being applied in more substantial ways. Every branch of mathematics employs some notion of product that enables the combination or decomposition of its elemental structures. In this paper, we consider strong product graph of Euler totient Cayley graphs with Arithmetic graphs and present some results on matching domination parameter of these graphs.


In composite manufacturing the knowledge and control of reinforcement orientation distributions is of central importance. The use of vision and image analysis techniques can greatly aid the production of composites by providing real time data regarding fiber orientation and distribution throughout a part. This acquisition of fiber orientation and position information is of special interest for domains around certain key geometric features and can serve as input into property predictions. In this paper it is demonstrated that through the use of a widely available and relatively inexpensive image analysis package as well as a simple USB digital camera it is possible to acquire accurate fiber orientation information for use in manufacturing of short fiber reinforced composites.


merchants who had a literary or official title, or gentry and merchants who had ties with the first two" groups as well as those "old-style literati" and "urban-based intellectuals" who favored reform (Educational Reform, pp. 16-17; Aspects, pp. 20-21). In Bastid-Bruguiere's opinion, the "modern gentry" was a transitional group. After 1901 its members became nationalistic and developed administrative skills that enabled them to initiate reforms effectively. As they gained experience and confidence they became impatient with the Qing court and its bureaucrats. But they were not revolutionaries; not a "conquering bourgeoisie" (Educational Reform, pp. 90-91; Aspects, pp. 101—2). Their ties to the traditional elite were too strong, and the revolution of 1911 left them behind. After the publication of Aspects de la reforme de I'enseignement en Chine in 1971 American reviewers praised Bastid-Bruguiere's achievement (seeJAS, 32, no. 1 [November 1972]: 145-46). Scholars, whether they agree with her or not, continue to cite this study in their monographs and articles. Is this translation useful? Yes—but it is unfortunate that this early work has been translated and published without some recognition of the development of the author's views since 1971. Nevertheless this translation will enable those who do not read French to make use of a pioneering study of the relationships among educational, social, and political changes in early modern China.


Shock waves, as shown by simulations and observations, can generate high levels of downstream vortical turbulence, including magnetic islands. We consider a combination of diffusive shock acceleration (DSA) and downstream magnetic-island-reconnection-related processes as an energization mechanism for charged particles. Observations of electron and ion distributions downstream of interplanetary shocks and the heliospheric termination shock (HTS) are frequently inconsistent with the predictions of classical DSA. We utilize a recently developed transport theory for charged particles propagating diffusively in a turbulent region filled with contracting and reconnecting plasmoids and small-scale current sheets. Particle energization associated with the anti-reconnection electric field, a consequence of magnetic island merging, and magnetic island contraction, are considered. For the former only, we find that (i) the spectrum is a hard power law in particle speed, and (ii) the downstream solution is constant. For downstream plasmoid contraction only, (i) the accelerated spectrum is a hard power law in particle speed; (ii) the particle intensity for a given energy peaks downstream of the shock, and the distance to the peak location increases with increasing particle energy, and (iii) the particle intensity amplification for a particular particle energy, f ( x , c / c 0 ) / f ( 0 , c / c 0 ) , ?> is not 1, as predicted by DSA, but increases with increasing particle energy. The general solution combines both the reconnection-induced electric field and plasmoid contraction. The observed energetic particle intensity profile observed by Voyager 2 downstream of the HTS appears to support a particle acceleration mechanism that combines both DSA and magnetic-island-reconnection-related processes.

Magnetic reconnection is one of the major particle acceleration processes in space and astrophysical plasmas. Low-energy supra-thermal particles emitted by magnetic reconnection are a source of ionisation for circumstellar discs, influencing their chemical, thermal and dynamical evolution. The aim of this work is to propose a first investigation to evaluate how energetic particles can propagate in the circumstellar disc of a T Tauri star and how they affect the ionisation rate of the disc plasma. To that end, we have collected experimental and theoretical cross sections for the production of H+, H$_2^+$ and He+ by electrons and protons. Starting from theoretical injection spectra of protons and electrons emitted during magnetic reconnection events, we have calculated the propagated spectra in the circumstellar disc considering the relevant energy loss processes. We have considered fluxes of energetic particles with different spectral indices and different disc magnetic configurations, generated at different positions from the star considering the physical properties of the flares as deduced from the observations obtained by the Chandra Orion Ultra Deep point source catalogue. We have then computed the ionisation rates for a disc whose structure has been calculated with the radiation thermo-chemical code ProDiMo. We find that energetic particles are potentially a very strong source of local ionisation with ionisation rates exceeding by several orders of magnitude the contribution due to X-rays, stellar energetic particles and radioactivity in the inner disc.


Emerging Non-Volatile Memories (NVMs) are promising contenders for building future memory systems. On the other side, unlike DRAM systems, NVMs can retain data even after power loss and thus enlarge the attack surface. While data encryption and integrity verification have been proposed earlier for DRAM systems, protecting and recovering secure memories becomes more challenging with persistent memory. Specifically, security metadata, e.g., encryption counters and Merkle Tree data, should be securely persisted and recovered across system reboots and during recovery from crashes. Not persisting updates to security metadata can lead to data inconsistency, in addition to serious security vulnerabilities.
In this paper, we pioneer a new direction that explores persistency of both Merkle Tree and encryption counters to enable secure recovery of data-verifiable and encrypted memory systems. To this end, we coin a new concept that we call Persistent-Security. We discuss the requirements for such persistently secure systems, propose novel optimizations, and evaluate the impact of the proposed relaxation schemes and optimizations on performance, resilience and recovery time. To the best of our knowledge, our paper is the first to discuss the persistence of security metadata in integrity-protected NVM systems and provide corresponding optimizations. We define a set of relaxation schemes that bring trade-offs between performance and recovery time for large capacity NVM systems. Our results show that our proposed design, Triad-NVM, can improve the throughput by an average of ~2x (relative to strict persistence). Moreover, Triad-NVM maintains a recovery time of less than 4 seconds for an 8TB NVM system (30.6 seconds for 64TB), which is ~3648x faster than a system without security metadata persistence.


In this study, model of lifting platform consisting of scissors and hydraulic cylinder is formed. Static state equations have been used for the mathematical model of the mechanism. The weights and mass inertia moments of the platform members and the upper table have been neglected. Vehicle load as a point force, the top of the table is closed at the moment when the mechanism is effective. The sliding in the joints have been neglected.The mechanism is modeled and simulated in order to evaluate several application-specific requirements such as dynamics, position accuracy etc. The system has a 5 degree of freedom. The simulation gives different link lengths of the mechanism over a linear displacement.


This paper discusses the application and experimental validation of time-optimal model predictive control (TOMPC) on a flexible motion system, an overhead crane with fixed cable length. TOMPC realizes minimal settling times for point-to-point motions taking into account system constraints. Results of several different point-to-point motion experiments and of disturbance rejection experiments clearly demonstrate this time optimal behavior. The extension of the TOMPC algorithm to increase its feasibility range required for large point-to-point motions is discussed and validated.


The invention relates to a configuration (1) of a component (2) and at least one test device (3) for recording a degradation (4, 40) of said component. Said test device has at least one electric oscillating circuit (31) and the component and oscillating circuit are interconnected in such a way that the degradation of the component causes a degradation (41) of the oscillating circuit and a modification of a detectable resonant signal of the oscillating circuit. The configuration is characterised in that the test device has at least one additional oscillating circuit (32) comprising an additional detectable resonant signal and that the oscillating circuit and the additional oscillating circuit are coupled to form a comprehensive oscillating circuit (30) comprising a detectable comprehensiveresonant signal that differs from the resonant signal and the additional resonant signal. The inventive component is for example a heat shield (20) of a combustion chamber in a gas turbine. The oscillating circuits are connected in parallel. Different high-frequency signals are received for an intact oscillating circuit and for a degraded oscillating circuit. The oscillating circuit consists of abrittle ceramic conductive material. A crack (degradation) in the heat shield continues as a crack in the oscillating circuit. The measuring signal received permits the degradation of the component to be reliably detected.

In Family Practice Volume 17 (December 2000), Jewell et al.1 presented the problem of British teenage women's needs for contraceptive and sex education in schools. The problem of teenage mothers is very widespread, but it is connected with the economic and cultural background of societies.2–4 At our department (Public Health and Social Medicine Department of Medical University of Gdańsk, Poland), we have conducted a similar study of teenage mothers. All teenage mothers who gave birth during the period from 1 July 1995 to 30 June 1996 at the Obstetrics Departments of Gdańsk (Poland) hospitals took part in our study. The information was gathered by personal interviews and a special questionnaire concerned with the family situation of teenage mothers, their social and economic status and that of their partners, and their knowledge of their ovular period and contraceptive methods. The results of our study proved that .40% teenagers did not know their ovular period and ~75% couples did not use any contraceptive methods. For the teenagers who know about their ovular period, the most common source of information was popular scientific books, less commonly the family home and only 11% of surveyed people indicated school as the place where they obtained their information (Fig. 1). Our results parallel those found in the UK study and emphasized the importance of including information about the ovular period and contraception in school programmes. In Poland, this kind of information is blocked by the catholic attitude of authorities. The natural method of birth regulation is promoted. On the other hand, we obtained different results, as far as the use of contraceptive methods was concerned, according to social and economic background. Young women from more socio-economically advantaged backgrounds used contraception twice as frequently as those from disadvantaged backgrounds. In Poland, contraception has to be paid for without any supplies by health funds. We also observed a difference in the use of contraception according to the education level of teenagers and their parents. Contraceptive methods were used more frequently by more educated teenagers (college education, 40.9%; technical college education, 36.84%). The less educated teenagers used contraception less frequently (21.47%). The lowest frequency of using contraception was observed in the group with only a primary level of education (5.88%). Furthermore, teenagers whose parents were well educated used contraceptive methods more often. From the gathered material, we also found that the groups of teenagers who described their economic status as medium or good used contraception more often, 7.84 and 10.03%, respectively. In the group of teenagers describing their economic status as very good or poor, the percentage using contraception was nearly half the above, from 4.39 to 2.19%.


Frankie Sionil Jose of the Philippines is among Asia's leading fictionist. In a career spanning more than half a century that included editing Solidarity, which promotes writing in and about Southeast Asia, he has produced a remarkable body of fiction. Apart from winning various prizes, he was a Ramon Magsaysay awardee (1980) and a National Artist for Literature (2001). This tribute, in commemoration of Jose's 80th birthday, brings together reminiscences, poems, a substantial number of essays, all published for the first time. The comprehensive bibliography is indispensable to all who wish to study his work. By leading scholars of Filipino literature, the essays examine such themes as nation, history and society in Jose's works, and his use of English, of myth, through an examination of single or groups of texts of which the quintet that form the Rosales Saga is the most notable. They provide a challenging explication and assessment that, together with the other contributions, make the volume an authoritative, stimulating introduction to Jose, and to Filipino and Asian literature in English(es). It should be in all major libraries.

Objective:To study the efficacy of buspirone on anxiety and drug craving of heroin dependent patients during detoxification. Method: Patients on detoxification were randomly divided into two groups, Group A, 70 cases, treated with methadone and buspirone; Group B, 70 cases, treated with methadone only. All of them took a 10 day treatment and were compared. They were expertized by Zung Anxiety Self-assessment Scale(SAS)and self-designed psychological drug craving scale. Result: The degree of anxiety and craving in Group A was obviously decreased more than that in Group B (P0.01). The adverse drug reactions of buspirone,such as headache,gastrointestinal symptoms and excitement didn't affect the therapy efficacy. Conclusion:Buspirone can reduce anxiety,craving and drug-seeking behavior in patients with heroin-dependence during detoxification.


Objective
To explore the effect of reduced alpha-cardiac actin 1(ACTC1) gene expression on the rat embryonic cardiomyocytes H9C2 cell apoptosis and its mechanism.

Methods
The rat embryonic cardiomyocytes H9C2 cell was cultivated; the rat embryonic cardiomyocytes H9C2 cell was transfected with ACTC1-small interfering RNA(siRNA), and at 24 h, 48 h, 72 h after transfection, the cells were collected for extraction and purification of RNA, the real-time quantitative PCR(qPCR) method was used to detect the expression level of ACTC1 gene; and the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay(TUNEL) method was used to explore the effect of reduced ACTC1 gene expression on the rat embryonic cardiomyocytes H9C2 cell apoptosis.Western blot was used to detect the expression of Cyto C, cysteine-containing aspartate-specific proteases(Caspase)-3, Caspase-8, Caspase-9, Bcl-2 and Bax.

Results
The expression of ACTC1 mRNA detected by qPCR decreased compared with that of the scramble siRNA group in 24 h, 48 h, 72 h(0.80 vs.1.00, 0.20 vs.1.00, 0.25 vs.1.00), and in the ACTC1-siRNA group decreased significantly at 48 h, 72 h, and the difference was statistically significant(t=4.245, P 0.05).

Conclusions
Reduced ACTC1 gene expression can induce the rat embryonic cardiomyocytes H9C2 cell apoptosis perhaps mainly through endogenous mitochondrial signal transduction pathways.

My contribution is based on an analysis of the voluntary realisation of the Access and Benfit-Sharing (ABS) stipulations of the UN Convention on Biological Diversity (CBD) by the pharmaceutical industry. Our research shows that on a voluntary basis the pharmaceutical industry realises ABS provisions of the CBD only to a very limited extent. We thus argue for the necessity of an legally binding ABS protocol on the basis of the Bonn guidelines.


Zusammenfassung The Homeric compound ἀρτιεπής can be understood as a possessive-compound with a case-form or an adverb in the first member. The compound can be connected to the idea of [CORRECT/RIGHT - SAY], and as such to the expression ἄρτια βάζειν 'to tell right things' (Hom.). A collocation [*(H)ar‑ - *u̯eku̯‑] lies at the basis of several IIr. compounds and collocations that are etymologically related to ἀρτιεπής: Ved. ṛtavāká‑, Av. arəm.uxti‑, Ved. [ṛtám - say]. Among others, some striking matches can be identified: Ved. ṛtvíya‑ vā́k‑ and YAv. raϑβiia‑ vacah‑, as well as YAv. vacah‑ - ratumant‑, where the tu‑derivatives parallel the ti‑derivatives (Gk. ἄρτι : *arti‑ or *art‑i‑); YAv. arš.uxδa‑, arš.vacah‑ (OAv. ərəš.vacah‑) which may be interpreted as structural matches, probably containing an adverb as first member of compound.


Request-for-proposals (RFP) are documents in IT tendering that define the selection criteria, evaluation procedures and system requirements including system usability. IT vendors' perspective on RFP-originated system configuration and usability design is less studied than of IT procuring organizations. Analysis of empirical data collected from large IT tendering shows that from the vendor's perspective the objectives and means of usability design during the tendering differ drastically from general usability work. During the tendering, the fundamentals of usability recommendations can be based solely on the requirements of RFPs with no adequate intention to improve system usability in the use context. An ethical analysis of the situation and possible futures and alternatives is represented.


Interleukin‐18 (IL‐18), a recently described cytokine produced mainly by macrophages, stimulates interferon‐γ (IFN‐γ) production by natural killer cells and T cells. Although it has been reported that serum IL‐18 levels are higher in patients with advanced tuberculosis and acute graft‐versus‐host disease compared with normal controls, the authors found no reports regarding serum IL‐18 levels in patients with malignant solid tumors. The purpose of this study was to determine serum IL‐18 levels and their clinical significance in patients with gastric carcinoma.

Based on the issue of enhancing oil recovery of heavy oil reservoir after steam injection, this paper studied the development characteristics of hot water flooding in different rhythm (positive rhythm, anti-rhythm, complex rhythm) reservoir after steam drive by means of physical simulation. The research shows that the positive rhythm reservoir has a large swept volume with steam flooding under the influence of steam overlay and steam channeling. Anti-rhythm reservoir has a large swept volume with hot water flooding, because hot water firstly flows along the high permeability region in upper part of the reservoir, in the process of displacement, hot water migrates to the bottom of reservoir successively for its higher density.


A low-power successive approximation register analog-to-digital converter with hybrid encoding DAC is proposed in this paper.To decrease the glitch of the charge redistributed DAC,the split-capacitor DAC adopt the hybrid code.To increase the matching accuracy and reduce the influence of parasitic effect of DAC,some matching techniques are adopted in the layout design of the proposed DAC and capacitor.The SAR ADC is fabricated and verified in GF(Global Foundry)0.35μm CMOS process.The measurement results have shown that at 500KSPS,the INL and DNL are-0.6~0.4LSB and-0.2~0.7LSB,respectively,the SNDR is 54.13dB and the ENOB is 8.7bits.The total circuit consumption is 537.9μW.


ZnO:Al/c-Si (1 1 1) isotype heterojunction photodetectors were fabricated by a chemical spray pyrolysis technique. High responsivity and good junction characteristics were obtained after post-deposition rapid thermal annealing (RTA). Dark and illuminated I–V characteristics were measured and analyzed. The ideality factor was deduced from I–V characteristics and found to be 1.3 after RTA. C–V measurements revealed that the junction was abrupt type. The energyband diagram, based on the Anderson model, was constructed from the electrical properties of the junction. Good photoresponses in UV and visible regions with responsivity were around 0.1 A W−1 and 0.47 A W−1, respectively. The rise time of the detector was improved after RTA and found to be 50 ns. These results suggest that the Al dopant could be a good choice to fabricate the doped ZnO/Si devices for photodetection and other optoelectronic applications. We describe here the fabrication process and optoelectronic characteristics of the photodetector.


Image quality assessment (IQA) has been a topic of intense research over the last several decades. With each year comes an increasing number of new IQA algorithms, extensions of existing IQA algorithms, and applications of IQA to other disciplines. In this article, I first provide an up-to-date review of research in IQA, and then I highlight several open challenges in this field. The first half of this article provides discuss key properties of visual perception, image quality databases, existing full-reference, no-reference, and reduced-reference IQA algorithms. Yet, despite the remarkable progress that has been made in IQA, many fundamental challenges remain largely unsolved. The second half of this article highlights some of these challenges. I specifically discuss challenges related to lack of complete perceptual models for: natural images, compound and suprathreshold distortions, and multiple distortions, and the interactive effects of these distortions on the images. I also discuss challenges related to IQA of images containing nontraditional, and I discuss challenges related to the computational efficiency. The goal of this article is not only to help practitioners and researchers
keep abreast of the recent advances in IQA, but to also raise awareness of the key limitations of current IQA knowledge.


This study investigates the role of information technologies (IT) in the governance of IT outsourcing relationships. Managers rely on contractual and relational governance to manage IT outsourcing projects. In addition, they use dedicated IT solutions to make the governance more efficient. While the role of IT in supporting the two governance approaches is appreciated in practice, it has not yet been comprehensively addressed in research. Through an exploratory case study comprising of five client and five vendor companies, this study investigates the impact of IT on contractual and relational governance. Our findings suggest that IT helps to support contractual governance in general and specific aspects of relational governance. In particular, vendors' selfcontrol is supported by IT. Further, we outline the facilitating role of IT to create transparency as a possible antecedent of trust.


The development of Information and Communications Technologies (ICT) has affected various fields including the automotive industry. Therefore, vehicle network protocols such as Controller Area Network (CAN), Local Interconnect Network (LIN), and FlexRay have been introduced. Although CAN is the most widely used for vehicle network protocol, its security issue is not properly addressed. In this paper, we propose a security gateway, an improved version of existing CAN gateways, to protect CAN from spoofing and DoS attacks. We analyze sequence of messages based on the driver's behavior to resist against spoofing attack and utilize a temporary ID and SipHash algorithm to resist against DoS attack. For the verification of our proposed method, OMNeT++ is used. The suggested method shows high detection rate and low increase of traffic. Also, analysis of frame drop rate during DoS attack shows that our suggested method can defend DoS attack.

The ridges delineating the drainage basins of a channel network and its subnetworks form themselves a network. This network spatially penetrates, or interlocks with, the channel network. Under fairly weak axiomatic assumptions, interlocking ridge and channel networks are of equal magnitude, and there exists a one-to-one relationship between their respective paths such that each pair of corresponding ridge and channel paths delineates a contiguous area called a drainage complex. In the limiting case that the link number of the channel path is zero, the complex coincides with the familiar concept of a drainage basin. Data sampled from natural ridge and channel networks indicate that, for a given complex magnitude, the link numbers of the two paths follow an essentially random distribution; in contrast, the sum of the link numbers is closely dependent on the complex magnitude. Thus, while the internal connectivity of any ridge or channel network in the study area seems to be largely a matter of chance, the respective connectivities of interlocking networks exercise tight control over each other. The observed dependency is interpreted as the result of both geometric and geomorphic constraints limiting the minimum and maximum length of drainage area boundaries. © 1988 Taylor & Francis Group All right reserved.


In recent years, responses of reinforced concrete (RC) structures subjected to loading from high-energy (HE) sources in their vicinity have been reported in the literature. Moreover, intensified terrorist activities have rekindled an interest in studying the response of these structures subjected to loads from both airblast and fragments. Numerical approaches for simulating structural response due to airblast loads have been addressed by many authors. Limited literature discussing numerical simulations of structural response due to fragment loads is available. Approaches simulating the response of RC structures subjected to multiple fragment impact are addressed in this study. A number of finite-element analyses using scalable hardware and software was carried out. The fragments are modeled both explicitly (actual geometric representation) and implicitly, using an "equivalent" loading function. Rate effects are incorporated in the constitutive models used for these analyses. Their importance is addressed in the discussion that follows. This paper discusses comparison of numerical simulation results with the experiments.


The CDC estimates that 80,000 central line associated blood stream infections (CLABSIs) develop each year in ICU environments. This estimate climbs to 250,000 CLABSIs per year when entire hospitals are included (CDC, 2011). CLABSIs have been found to be the second most deadly type of hospital acquired infection . The yearly cost of CLABSIs is greater than on billion and costs per individual patient with a CLABSI can exceed $16,000. CLABSI can result in an extended length of hospital stay and increase the financial cost of treatment considerably. These consistently high rates of CLABSIs, despite the adoption of standard prevention techniques by most hospitals, indicate the need for more effective interventions.


Concerns raised about the lack of preservation initiatives and poor access to global scientific knowledge in the form of primary research data and records for research in the turn of the 20th century resulted in the development of a variety of ways to remedy the inadequacies associated with scholarly research data/products and dissemination of knowledge pertaining to research activities. The aim of the paper is to examine the needs for the surveyed social science research institutions in Malaysian government for the preservation of their digital primary research data. This paper presents the findings of the survey questionnaires of the existing practices on the preservation of primary research data in the selected Malaysian research institutions and related organizations. The questions asked in the survey were based on the elements of the generic preservation framework.


Introduction "e objective of this brief communication is to review how development of spreadsheet and computer simulation models of Rangifer biology/ecology has in#uenced construction of the CircumArctic Rangifer Monitoring and Assessment (CARMA) energy/protein model, which simulates body weight and condition and reproduction characteristics of a female caribou (Rangifer tarandus) in response to environmental inputs and reproductive history. A full description of input variables, driving algorithms and output variables of the CARMA energy/ protein model is being written for a peer-reviewed publication.

In this publication we give rationale for algorithms and we justify the hierarchy used to allocate energy and protein resources throughout the model. Also in preparation is a publication that addresses veri$cation of key algorithms and performs a sensitivity analysis of key components of the model. "is review is restricted to models speci$c to Rangifer and published since the early 1970s. It covers the scope of input that in#uenced our modeling process and has import to understanding modeling of caribou biology and ecology in the last 40 years.


A potent intracellular-lipid-producing yeast, Rhodotrorular glutinis var. glutinis sw-17 was studied on the production of carotenoids after shaking the cultures for 8 days at . The pigments were extracted with solvents and chromatographed with columns for its isolation. The carotonoids were identified by their positions on the column, and by their light-absorption curves. Close agreement was obtained between the absorption maxima of the isolated pigments and published literature values. The characteristic wave length maxima and the extinction values used for quantitative determination. The caroteniod pigments produced by the yeast were composed of torularhodin(28.52%), torulene(38.16%), neurosporene(1.49%), , -zeacarotene(2.0%), and .


The zeta potential on the surface of reservoir sandstone in different media of pH is measured by using SurPASS Electrokinetic Analyzer.The results show that the measurement of the zeta potential on the surface of the reservoir sandstone is suitable when the pH of media is between 7 and 10.It is because when the pH is lower than 7,there will be chemical reaction between the surface of the sandstone and the solution of the media,and when the pH is higher than 10,there will also be chemical reaction between the solution of media and the aluminum on the surface of the reservoir sandstone.The pretreatment of the samples whose surface zeta potential needs to be measured is preliminarily studied.The result shows that the repeatability of the surface zeta potential measurement of the samples pretreated with NaOH is better than that of the samples untreated.


To prevent heart attack, stroke, or death, the American Heart Association recommends estimating patients' absolute risk of having a coronary heart disease (CHD) event in 10 years. Before physicians adopt routine risk calculation, we should use the evidence to determine the best use of our patients' time and resources.
