ABSTRACT

Internet of things (IoT), being the technology of this generation and several billions of electronic devices exchanging a huge secure information. With the low resource devices like the sensors, RFIDs etc. to the super computers and the clouds the security and privacy issues remain a concern. While the conventional cryptographic algorithms approved by the National Institute of Standards and Technology, could be embedded into the Low-resource devices their performance may be reduced, then the design of Ciphers for such resource constrained devices become a challenge with the security principles confidentiality, Integrity and Availability remains the same.This paper proposes, simple encryption schemes based on arithmetic operations Addition-Modulo/Multiplication Modulo, Rotation and XOR hence the name ARX/MRX. The cipher schemes have been implemented using reversible logic and Vedic Mathematics. The adders have been implanted using reversible logic and multipliers and the modular algorithms have been implemented using the combination of Vedic maths and Reversible logic. The software and hardware implementations are presented. The Histogram, Correlation coefficient and Entropy are found for the grayscale plaintext image using MATLAB to evaluate the security, and the hardware implementation is done writing Verilog code using Xilinx-Vivado and is verified using Nexys-4 Artix-7 FPGA the performance of the encryption schemes are analysed and compared with the existing literature.

What is the reason for the formation of these difficulties? How to help students solve there problems in guiding them to learn? After years of teaching experience on these issues,the authhor summarizes some of the experiences,elaborate the detailed information in this paper.


obtained from the parents. The date of the infection could not be determined. Such positive laboratory evidence of past toxoplasmic infection is frequently obtained in persons in an older age group.2 A negative reaction to a toxoplasma complement-fixation test does not vitiate this observation, since such antibodies seem to disappear shortly after infection or the last contact with the antigen.13'


The hydraulic fracturing problems in fields of water conservancy and hydropower and mining are produced by natural hydraulic power.Its boundary conditions are different with them in artificial hydraulic fracturing applied to fields of petroleum and natural gas.The characteristics of hydraulic fracturing under natural power are generalized.The study level of hydraulic fracturing is divided into two based on study measure.The one is based on macroscopical,synthetical and statistical characteristics medium.The other is focused on a single fracture and a group of fracture with regular location.The characteristics of fracture flow are analyzed.In order to simplify the research,the hydraulic fracturing process of a single fracture can be divided two stage or two kinds.The different fracture flow models are proposed.


The purpose of the present document is to identify and expose the theoretical and practical benefits of compensating the physical damages caused by the State, using the damage to healthþas an independent and autonomous immaterial damage, displacing the `damage to life in relationþ and the alterations of the conditions of existence, as autonomous immaterial damages, due to the critics done by the states council of Colombia as the maximum administrative tribunal.

PURPOSE: A polling method of a protocol data unit in a transfer buffer is provided to operate stably a transmission system of a protocol data unit by setting falling bits for one or more protocol data units. CONSTITUTION: Protocol data units requested from a lower layer are sequentially selected from a transfer buffer in order to transfer the protocol data units(S201). The number of the protocol data units are requested by the lower layer. The selected protocol data units are compared with the last protocol data unit within the transfer buffer(S202). The selected protocol data units are compared with the last protocol data unit within a transmission window(S203). A polling bit set in the corresponding protocol data unit and the corresponding protocol data unit is transferred to a receiving side if the selected protocol data unit is the last protocol data unit(S204,S205).


Platforms are defined as multisided marketplaces with business models that enable producers and users to create value together by interacting with each other. In recent years, platforms have benefited from the advances of digitalization. Hence, digital platforms continue to triumph, and continue to be attractive for companies, also for startups. In this paper, we first explore the research of platforms compared to digital platforms. We then proceed to analyze digital platforms as business models, in the context of startups looking for business model innovation. Based on interviews conducted at a technology startup event in Finland, we analyzed how 34 startups viewed their business model innovations. Using the 10 sub-constructs from the business model innovation scale by Clauss in 2016, we found out that the idea of business model innovation resonated with startups, as all of them were able to identify the source of their business model innovation. Furthermore, the results indicated the complexity of business model innovation as 79 percent of the respondents explained it with more than one sub-construct. New technology/equipment, new processes and new customers and markets got the most mentions as sources of business model innovation. Overall, the emphasis at startups is on the value creation innovation, with new proposition innovation getting less, and value capture innovation even less emphasis as the source of business model innovation.

Corrosion of reinforcement embedded in concrete is considered as one of the main reasons for the degradation and deterioration of many existing reinforced concrete structures and this degradation effects has been seen as major challenges in structures founded in region with high concentration of salt as in the case of the Niger Delta region of Nigeria. This study involves the coating of ficus sycomorus exudates/resin paste of plant trunks extract known as inhibitors directly on the reinforcing steel. The experiment aimed at determining the effectiveness in the use of ecofriendly and abundantly available materials in curbing the negative effect of corrosion attacks on reinforcing steel embedded in concrete structures and immersed in Sodium Chloride (NaCl) solutions by coating steel reinforcement with different thicknesses and experimentally tested to prevent corrosion attacks in the laboratory. The test specimens reflect the acute acidic level indicating the sea salt concentration level of the marine environment on reinforced concrete structures. The result showed that the decreased value in uncoated (corroded) represent the degree of corrosion that has to affect the bonding interaction between concrete and reinforcing steel, also, the negative values obtained in bond strength versus maximum slip showed that the reduction in slip was due to the effect of corrosion. The higher values obtained from coated members showed the potential and the effective interaction process in steel and concrete, results showed that the values of coated members are similar to that of controlled indicating the virtuous bonding characteristics. The result of weight loss for controlled samples are 100% indicating no weight loss, uncoated (corroded) samples negative values showed tremendous weight loss resulting from corrosion presence, and for coated samples, there are weight gain resulting from coating materials. Also, the effect of corrosive medial reduces the diameter of reinforcing steel after corrosion, the effect of corrosion formed pits which resulted to swollen rebar surface whereas coated and controlled maintained perfect diameter with an increasing diameter from coating thicknesses. Reduction in cross–sectional properties, weight loss was all seen in corroded samples resulting from damaging and destructive effect from corrosion manifestation while coated gained weight and as well as increased in cross-sectional properties. Clear examinations on the study and investigations, coated exudate/resin has demonstrated and shown to be good inhibitive material against corrosion.


The title compound, [Li2(C12H10NS)2(C4H8O)4], exists as a dimer in the solid state, with a central four-membered Li2N2 ring that is planar by crystallographic inversion symmetry. The Li atoms are bridged by the N atoms of two anilide ligands, and each Li atom is coordinated by two O atoms from tetrahydrofuran ligands, resulting in a distorted tetrahedral N2O2 environment. One of the tetrahydrofuran rings is disordered over two sets of sites in a 0.665 (16):0.335 (6) ratio.


Tube hydroforming is a process to manufacture lightweight components,especially automotive parts,with advantages of cost and weight reduction,better structural integrity and increased strength and stiffness over the conventional process.For hydroforming a Y-shape tube,ratio of left axial feed and the right has a remarkable impact on the forming process due to non-symmetric structure.The effect of this ratio on thickness distribution and forming defect was investigated through experiments and numerical simulation.The results show that after forming the left fillet transition region is the thickest,the right is thicker and the top of the protrusion is the thinnest.It can reduce the thinning tendency through increasing the ratio of axial feed.However,an excessive ratio of axial feed will lead to dimpling and even wrinkling.A reasonable ratio zone of axial feed for hydrforming Y-shape tube is confirmed.


Cognitive Stimulation Therapy (CST) is an evidence-based therapy recommended for individuals who have been diagnosed with mild to moderate dementia, however its effectiveness for people with Mild Cognitive Impairment (MCI) has not been explored. This research update briefly outlines Cognitive Training and Cognitive Stimulation as cognitive intervention options for MCI, before positing that the offer of CST should be extended to those diagnosed with an MCI. This is discussed in relation to the limitations which exist around MCI diagnosis as a whole, as well population ageing and conversion rates between MCI and clinical dementia. We conclude by outlining the CST provision which we intend to provide within our Memory Clinic for those recently diagnosed with an MCI.

The need to increase power, to improve fuel economy and to meet stringent exhaust emissions legislation with a high level of refinement has provided a challenge for the design of a compact high-speed direct injection (HSDI) diesel engine. This paper describes various aspects of cylinder head design with particular consideration of layout and number of valves, valve actuation, port selection strategy, fuel injection systems and cylinder head construction.


: The text attempts to bring light to significant events connected to the creation and closure of the academic studies in ethnography and ethnology at the Faculty of Philosophy in Skopje in the early socialist period of 1946 to 1953. The analysis includes archived materials from the archives of the Faculty of Philosophy, and the Ministry of Education of the Socialist Republic of Macedonia. Emphasis has been placed on the socio-political conditions during which the studies were begun and shortly after that closed. The paper notes the social and local political and ideological frameworks for living in the socialistic community. Questions connected to the rise and fall of national ethnology in the Socialist Republic of Macedonia are related to ideological frameworks for how socialism's dealt with rural life, royalism, backwardness, traditionalism in contrast to urban employment, communism, progress, and modernity.


― ― A 100-year-old female consulted a local physician due to a positive fecal occult blood test. As abdominal CT examination suggested a tumoral lesion near the transverse colon, she was referred to our department. The coronal view of abdominal CT performed at our hospital revealed circumferential wall thickening from the ascending colon to the hepatic flexure and mild dilation of the intestine on the oral side, but no liver metastasis or ascites was noted. The thickened part had invaginated into the intestine on the anal side, suggesting intussusception. Lower gastrointestinal endoscopy could not reach the tumor due to debris. Based on the above findings, with a diagnosis of right-sided colon cancer complicated by intussusception, laparoscopic surgery was performed. Intraoperatively, the ascending colon was found to have invaginated into the end of the ileum, the intestinal wall was thickened and was difficult to elevate, but right colectomy could be performed under laparoscopy. In the resected specimen, a type I tumor of the cecum had invaginated into the ascending colon, but no intestinal necrosis was observed. Emergency laparotomy is often selected for adult patients with intussusception, but elective and laparoscopic surgery could be performed in the very old patient presented here.

It is known that atrial fibrillation (AF), the most common supraventricular cardiac arrhythmia (1), is associated with increased mortality and morbidity, with cerebral thromboembolism representing the most serious and threatening complication.


The Kagome Heisenberg antiferromagnet is mapped onto an effective Hamiltonian on the star superlattice by Contractor Renormalization. Comparison of ground state energies on large lattices to Density Matrix Renormalization Group justifies truncation of effective interactions at range 3. Within our accuracy, magnetic and translational symmetries are not broken (i.e. a spin liquid ground state). However, we discover doublet spectral degeneracies which signal the onset of p6 - chirality symmetry breaking. This is understood by simple mean field analysis. Experimentally, the p6 chiral order parameter should split the optical phonons degeneracy near the zone center. Addition of weak next to nearest neighbor coupling is discussed.

The International Space Station provides a unique microgravity laboratory environment for research. The ISS also serves as an effective platform for the development of technologies and engineered solutions related to living and working in space. The space environment also challenges our capabilities related to lubrication and tribology. In this seminar, Dr. DellaCorte will review the basics of space mechanism tribology and the challenges of providing good lubrication and long-life in the harsh space environment. He will also discuss recent tribological challenges associated with the Solar Alpha Rotary Joint (SARJ) bearings and life support hardware that must operate under severe conditions that are literally out of this world. Each tribology challenge is unique and their solutions often result in new technologies that benefit the tribology community everywhere, even back on Earth


Is it possible today in the age of globalization to create new modes of cross-cultural art based on a comprehensive understanding of one culture without being accused of mimicking or exploiting another? This paper includes the presentation of an example of contemporary western video art that attempts to explore cross-cultural influences between the West and the East, and to discuss this question from the western perspective. Proceeding from Chinese thought and aesthetics, the traditional concept of landscape painting "Shan-Shui-Hua" ("mountain-water painting") is recreated within the new western genre of the "video-painting" as a single (flat) screen video installation. Confronting the tools of modern computer visualisation with the East Asian concept creates an artistic artefact counter-pointing and reflecting both positions.


Abstract Rapid and simple method for serum and urine iodine is necessary for iodine-related diseases. This study aimed to establish and validate a simple and rapid method for quantification of iodine in human urine and serum using inductively coupled plasma mass spectrometry (ICP-MS). Generally, samples were diluted using water with 1.5% isopropanol and 7 mmol hydrous ammonium before analysis by the ICP-MS. Performance of the method was validated, and the urine and serum iodine levels of 72 pregnant women were analyzed. Results showed that the lower limit of detection of the ICP-MS method was 0.87 µg/L. No significant memory effects were observed. Recovery in both serum and urine was approximately 100%. Compared with NIST SRM3668, bias was <1%, exhibiting good accuracy. The inter-run coefficients of variation (CVs) for serum and urine iodine were 2.8–3.5% and 3.5–6.7%, respectively, and total CVs for serum and urine iodine were 3.2–3.7% and 3.9–6.7%, respectively. Comparison of the iodine results obtained by the ICP-MS method and the conventional S–K method revealed excellent correlation (r = 0.984, mean bias = –1.7%). The median urine iodine of pregnant women (125.5 μg/L) was lower than that of WHO criteria for iodine deficiency (median urinary iodine <150 μg/L) while 55.6% of the individuals with urine iodine level less than 150 μg/L. The median serum iodine level of the pregnant women was 69.0 μg/L. In conclusion, a rapid and simple ICP-MS method for urine and serum iodine measurements has been established and validated, and the pregnant women in Beijing may still suffer from insufficient iodine intake.

The present study examined the usability of ETOPO1 digital elevation model for small scale maps. The horizontal generalization of the contour lines generated from ETOPO1 was based on a geoinformatics algorithm. The authors gave the reduction values of simplification for the algorithm, and assigned these values to each map scale. The vertical generalization was examined by a diagram made on the frequency of the depths. The contour lines of the presented maps were based on the most frequent values of depths, though other criteria were also considered. The calculated values were compared with the earlier assigned values for the whole world. The examined area was the Arctic Ocean; therefore, the determined calculated values are valid for this region only.


In quantum gravity, one seeks to combine quantum mechanics and general relativity. In attempting to do so, one comes across the `problem of time' impasse: the notion of time is conceptually different in each of these theories. In this seminar, I consider the timeless records approach toward resolving this. Records are localized, information-containing subconfigurations of a single instant. Records theory is the study of these and of how science (or history) is to be abstracted from correlations between them. I explain how to motivate this approach, provide a ground-level structure for it and discuss what kind of further tools are needed. For a more comprehensive account with many more references, see [1].


In supersonic expansion flows of humid nitrogen, at relatively low cooling rates, self-sustained oscillations may occur due to the combined effects of nucleation, droplet growth, and latent heat release. Different modes of oscillation are found depending on the initial humidity. It is shown numerically that the stability limit and the oscillation frequencies of the different modes strongly depend on the nucleation rate. Numerical results are compared with experiments of Adam and Schnerr and own experiments for nozzles of different shapes. The ICCT nucleation model yields correct results for both series of experiments, when corrected with a factor of the order of 0.01.


The synthesis of β1–16-corticotropin methyl ester is described(14). As in previous work from these laboratories, t-butyl- and t-butoxycarbonyl groups were employed for the protection of side chain carboxyl and amino groups, respectively. This warrants excellent yields in the critical last step of the synthesis of large polypeptides: the removal of blocking groups. The compound was shown to be pure by thin layer chromatography on silicagel, by electrophoresis on paper, by amino-acid analysis, and by digestion of the total hydrolysate with L-amino-acid oxidase of snake venom. The ACTH-activity displayed was 5–10 U/mg in the in vitro assay of Saffran & Schally(4) and less than 1 USP-U/mg in the subcutaneous test according to Sayers(5) (solution in 1% gelatin).


A general error prediction and compensation scheme which implicitly includes the non-rigid body condition is developed for an arbitrary multi-axis machine. The accuracy and precision of tasks performed by multi-axis machines are profoundly affected by their volumetric accuracy. The volumetric accuracy of a machine depends on numerous factors, including geometric and kinematic errors, motion induced errors, deformation of structural members due to static and dynamic loads, and thermally induced errors. To alleviate the influence of these factors on the outcome of a task, a passive online software compensation method is developed. The method is based on two components: an interpolation algorithm with shape functions for error prediction and a recursive online software compensation scheme. Several illustrative examples are included.<<ETX>>


Sleep apnea is a potentially fatal disorder that causes frequent breathing pauses during sleep. Prior research has shown that monitoring of EEG signals during sleep can contribute to automatic detection of apnea events. However, a more comprehensive classification of specific apnea types and their severity is required for accurate clinical diagnosis and real-time detection of critical apnea episodes. In this study, we employed annotated EEG signals from 25 apnea patients and constructed two distinct classifiers using EEG frequency domain and non-linear features for binary classification of apnea severity and multiclass classification of apnea types. In both classification problems, three models i.e. Support Vector Machine (SVM), Linear Discriminant analysis (LDA) and Naive Bayes (NB) were evaluated and compared. Results showed that SVM model performed the best in both classification problems reaching accuracy higher than the baseline level. The SVM performance in the binary classification of apnea severity was acceptable (76% mean accuracy) however in the case of multiclass classification of apnea types, the SVM classifier did not reach acceptable performance for all apnea types (48% mean accuracy). Our findings illustrate that in addition to the detection of apnea episodes, EEG signals can be used in classification of apnea severity, which could lead to development of accurate diagnostic systems for automatic assessment and management of sleep disorders.


We consider the classical version of the optimal partial transport problem. Let μ (with a mass of U ) and ν (with a mass of S) be two discrete mass distributions with S ≤ U and let n be the total number of points in the supports of μ and ν. For a parameter α ∈ [0, S], consider the minimum-cost transport plan σα that transports a mass of α from ν to μ. An OT-profile captures the behavior of the cost of σα as α varies from 0 to S. There is only limited work on OT-profile and its mathematical properties (see Figalli (2010)). In this paper, we present a novel framework to analyze the properties of the OT-profile and also present an algorithm to compute it. When μ and ν are discrete mass distributions, we show that the OT-profile is a piecewise-linear non-decreasing convex function. Let K be the combinatorial complexity of this function, i.e., the number of line segments required to represent the OT-profile. Our exact algorithm computes the OT-profile in Õ(nK) time. Given δ > 0, we also show that the algorithm by Lahn et al. (2019) can be used to δ-approximate the OT-profile in O(n/δ + n/δ) time. This approximation is a piecewise-linear function of a combinatorial complexity of O(1/δ). An OT-profile is arguably more valuable than the OT-cost itself and can be used within applications. Under a reasonable assumption of outliers, we also show that the first derivative of the OT-profile sees a noticeable rise before any of the mass from outliers is transported. By using this property, we get an improved prediction accuracy for an outlier detection experiment. We also use this property to predict labels and estimate the class priors within PU-Learning experiments. Both these experiments are conducted on real datasets.


This paper shows the influence of bond deterioration between concrete and reinforcement in the behavior of RC frames. Wide beam-column connections and short elements, two cases where this phenomenon is particularly important are investigated. In this work, a model that simulates bond deterioration under cyclic loading is presented. The model combines the plastic hinge concept with continuum damage and fracture mechanics. The model uses a parameter named "slip moment". The calculation of this parameter is based on the bond strength of RC sections.


Scholars dedicated to literary theory have, in the last few years, created a heated debate about feminine voice, feminine space, feminist vs. feminine within a seemingly phallocentric society. The debate usually ranges from a passive acceptance of the writings of the major psychoanalytical theorists to the full rejection of their ideas. Ann Rosalind Jones, in her article, "Writing the Body: Toward an Understanding of L'Ecriture Feminine," describes a sub-controversy of the debate, namely, the French theorists' view of feminism (Showalter 361-77). Poststructuralist theory itself is a product of decentering theory. One begins to question all foundations, and, by so doing, questions the basic foundation-language. Language, it is often argued, is a masculine artifice and therefore cannot express "femaleness." The debate will continue to provide us with subject matter for many articles and professional meetings to come. It seems that when discussing writing by women, we fall into this debate whether we like it or not. Thinking through this debate provides the premise for the present paper. My purpose here is to show that a talented writer who is also a literary critic and professor of literary theory responds to these issues by writing a novel. Indeed, as I have already proposed elsewhere (McClendon 24), I believe that in Brazil today, theory has been driving literature rather than analyzing it. In this study, I will look at Helena Parente Cunha's text as a response to the post-structuralist writers Derrida, Foucault, and Lacan specifically. We will leave for another context the issue of the French theoretical point of view in Brazilian letters. Suffice it to say here that French thought (pre)dominates in Latin America as it does in Anglo America. I believe that Parente Cunha's text itself, the finished product, is one way to express that which is intuitive within the theories, but onerously expressed, since our only recourse is language that, in itself, is an artifice. When Mulher no espelho appeared in 1983, Helena Parente Cunha had been a Professor of Literary Theory in the Federal University of Rio de Janeiro for fifteen years. The book, her first novel, followed the publication of several volumes of poetry and short stories. In 1982, the manuscript for the novel won the Premio Cruz e Sousa, second place in the Concurso Nacional de Romance in Brazil, primarily for its "solid psychological synthesis of woman/women without precedent in Brazilian literature, not merely for its possibly confessional aspect, but also above all its profoundly revelatory qualities, in language immensely suited to its aims" (qtd. in Ellison and Lindstrom v). While I argue that on one level, reading only through feminist theoretical eyes, we see the psychological process of individuation at work, I believe that this text and others by contemporary Brazilian authors, men and women, are more complex and involve other theoretical issues. Therefore, I would like to direct our thought away from the feminist/feminine point of view for the moment. My argument, as stated before, is that Parente Cunha is "working through" the maze of post-structuralist


Psychosomatic research findings and concepts carry with them an implication of a dualistic position on the mind-body problem. In the light of present neurobiological evidence a dualistic position can no longer be supported. There is some evidence in favor of an isomorphism between mind and brain and mind and body, and more extensive evidence supports a modified identity theory. The evidence is briefly reviewed in this paper.


Current criticism of the performance of American governments is often organized around an emergent theory of intergovernmental decay, which contains propositions about government size, accountability, control, capacity and achievement among its central assertions. Recent evidence of American governmental performance is used to appraise the decay theory, leading to the conclusion that the evidence offers little support for its major assertions. An alternative approach is then sketched out, based on the structural concept of "organizational interest" and the inherent dynamism of a system in which every governmental unit is always part of the relevant political environment of at least one other unit. These considerations lead to a somewhat different assessment of the "problems"facing American governments as well as an alternative way of conceptualizing their activities.


We present the measurements on absolute total and partial ionization cross sections and fragmentation studies for DNA base Adenine on electron impact using a newly designed experimental setup which uses Time of Flight Mass Spectrometer and the relative flow technique.


From the perspective of property right reform of state-owned enterprises( SOEs),this paper explores the interaction effects among executive compensation,corporate dividends and enterprise performance of SOEs,in which a simultaneous equation model is established by selecting the data of SOEs in the years from 2006 to 2013. Further,executive compensation is divided into dominant compensation and implicit compensation. The results show that the dominant compensation,to a certain extent,has the effect of the incentives to enhance corporate value,which also has a positive effect on corporate dividends. At the same time,the implicit compensation also have a positive effect on corporate dividends. Finally,by coordinating the conflict of interest between managers and shareholders,it puts forward the scientific policy recommendation and implementation scheme to design SOEs' incentive mechanism and constraint mechanism.


An annual study was carried out in the Mandovi, a mangrove dominated tropical estuary to assess the contribution of particle-associated bacteria (PAB) to the system's variability in terms of abundance and productivity. The suspended load, which was composed of inorganic mineral grains and allochthonous materials including mangrove litter, was high during the southwest monsoon season (sw monsoon). The ratio of organic:inorganic content of these particles was low during the pre- and post-monsoon seasons. The PAB abundance ranged from 1.0 x 10 10 m -2 to 22.8 x 10 10 m -2 and accounted for 4 to 94% of the total bacterial abundance. The variation in PAB abundance was due to their preferential colonization, which depended on the quantity and quality of the particles. The average annual PAB production was 214 μg.C.m -2 d -1 and contributed to an average of 35% of the total bacterial production. The primary productivity (PP) was 137, 14 and 163 μg.C.m -2 d -1 for the pre-monsoon, sw monsoon and post-monsoon periods respectively. The calculated maximum bacterial carbon demand (BCD) of PAB was 37% of the total BCD. On an annual basis <1% of PP contributed to PAB-BCD. It is suggested that the rest of the BCD was met from mangrove litter, and other allochthonous sources. PCA analysis showed that biotic parameters were predictors for ~ 50% of the variability and had a marked seasonality linked to salinity. The allochthonous sources contributed significantly to the structure of the biological community of this mangrove dominated estuary.


Red ginger has active chemical compounds that are beneficial for health. Besides being abundantly available, red ginger also has potential as a natural preservative. The content of active chemical compounds, antimicrobial activity, and protease enzyme support natural preservation methods in the food industry. This study aimed to determine the effect of red ginger concentration on the physical and organoleptic qualities of buffalo meat. The research method was experimental using a completely randomized design with 4 treatments and 5 replications. The treatment consisted of R0 = 0%; R1 = marinade using 20% red ginger concentration; R2 = marinade using 40% red ginger concentration; R3 = marinade using 60% red ginger concentration. The results showed that red ginger concentration had a significant effect (P<0.05) on cooking loss and colour. Red ginger concentration had a very significant effect (P<0.01) on the pH value, tenderness, and aroma but had no significant effect (P>0.05) on the water content of buffalo meat. This research concludes that marinating using red ginger biomass can improve the physical and sensory qualities of buffalo meat during storage. Red ginger biomass had the potential as a spice that can be applied sustainably to improve the buffalo meat quality.


In this paper, we study how Lesbian, Gay, Bisexual and Transgender people (LGBT) students in Icelandic upper secondary schools interpret their experience of heteronormative environment and how they respond to it. The aim is to explore how sexualities and gendered bodies are constructed through 'schooling'. The article draws on interview data with seven LGBT students who attended five different upper secondary schools. We also use visual data collected during fieldwork at one upper secondary school and exemplify the results with a poster and a digitalised short-film, produced by the students, to substantiate what participants told us in the interviews. All of the students experienced heteronormative discourse and lack of respect and indicated that they did not feel fully accepted in school. Upon entering the classroom, the visibility of LGBTs and discussion about different performances of gender and sexuality seem to disappear, whether in terms of textbooks, course content, teaching practices and school environment. Furthermore, LGBTs and those who do not conform to the hegemonic performances of gender are often constructed as deviations from the norm, strange, and even depicted as the abjected other. This applies in particular to the informal school, which embraces the traditions, culture and social interactions among students and teachers. This othering occurs, despite relatively positive attitudes towards LGBT people in Icelandic society in general. The results signify a gap between policy and practice as regards the positioning of LBGT students, which affects their schooling and well-being.


A time-dependent non-adiabatic formulation is considered for chemical reactions. Basic algorithms are presented for the photodissociation of CH3I under the influence of strong short laser pulses. Detailed insight into the dynamics of this process is demonstrated. A time-dependent self-consistent field approach is suggested when many degrees of freedom have to be considered simultaneously. The derivation is based on a Liouville space description for which quantum and classical mechanics are treated on equal grounds. A multiconfiguration approach is formulated for explicitly including correlation due to splitting of the probability density and for non-adiabatic motion.


Abstract Complexes of 4-acetylbiphenyl thiosemicarbazone with Cu(II), Ni(II), Co(II) and Zn(II) ions have been synthesized and characterized by means of elemental analyses, IR and electronic spectroscopy, conductivity and magnetic susceptibility measurements. The ligand functions as a monobasic bidentate ligand bonding through the thiolate sulphur and azomethine nitrogen. Structures are proposed for the complexes. The formation constants of the complexes were determined using graphical methods.

One Vision of Arts Education: Project Zero's The Qualities of Quality: Understanding Excellence in Arts Education S. Seidel, S. Tishman, E. Winner, & P. Hetland. (2009). The Qualities of Quality: Understanding Excellence in Arts Education. Cambridge, MA: Harvard University, Project Zero.PDF available from Wallace Foundation website: http://www.wallacefoundation.org/KnowledgeCenter/ KnowledgeTopics/CurrentAreasofFocus/ArtsParticipation/Documents/Qualities-of-Quallty-Understanding-Excellence-Arts-Education.pdfThe Quality of QualitiesThe Wallace Foundation (2009) with support from the Arts Education Partnership (2009) commissioned Harvard's Project Zero (2009) to conduct a study of what constitutes quality arts education in the United States. The collaboration among these three groups has resulted in The Qualities of Quality: Understanding Excellence in Arts Education (Seidel, Tishman, Winner, & Hetland, 2009). Foundations may fund whatever interests their boards and officers. Advocacy groups promote causes. Researchers, we like to think, use theory to guide dispassionate inquiry into phenomena and events. The collaboration of these three organizations makes it appropriate to ask whether the report is inquiry or advocacy? Quality arts education according to whom? Quality in what contexts? Quality to what end? These are the questions that underlie this review.When I taught in England at the Birmingham College of Art and Design in 1971, 1 carried the one book that I thought represented the cutting edge of arts inquiry in the United States: Nelson Goodman's Languages of Art (1968). Goodman suggested that a knowledge of symbol systems may provide guidance in dealing with problems of education in novel ways.Once the arts and sciences are seen to involve working with - inventing, applying reading, transforming, manipulating - symbol systems that agree and differ in certain specific ways, we can perhaps undertake pointed psychological investigation of how the pertinent skills inhabit or enhance one another; and the outcomes might well call for changes in educational technology. (Goodman, p. 265)Goodman examined and compared phenomena such as pictures, musical scores, and dance notation, thus, calling attention to seldom investigated symbol systems used in the arts. He founded Harvard's Project Zero to conduct that investigation. The name came from the assumption that since no inquiry base existed upon which to build, the starting point was zero. Project Zero's first codirectors, Howard Gardner and David Perkins, produced an impressive body of inquiry pertaining to the arts and cognition. Just one example, Gardner's multiple intelligence inquiry, seems precisely to fulfill Goodman's dream (Gardner, 1983). Educators the world over, sometimes to Gardner's chagrin at the distortion of his ideas, have implemented educational programs based on attention to a variety of symbol systems. So where does Qualities of Quality fit within the Project Zero enterprise?In their Executive Summary, Project Zero's researchers state that, "Many children in the United States have little or no opportunity for formal arts instruction and access to arts learning experiences remain a critical national challenge. In addition, the quality of arts learning opportunities that are available to young people is a serious challenge" (Seidel et al., 2009, p.l ).The evidence for these claims is not presented - which may be a tip-off that what is to follow is at least as much advocacy as it Is empirical inquiry. Nevertheless, the research questions are empirical:* How do arts educators in the United States - including leading practitioners, theorists, and administrators - conceive of and define high quality arts learning and teaching?* What markers of excellence do educators and administrators look for in actual activities of arts learning and teaching as they unfold in the classroom?* How do a program's foundational decisions, as well as its ongoing day-to-day decisions, affect the pursuit and achievement of quality? …


Background: Automatic classification techniques provide tools to analyze complex data and predict disease progression. Methods: A total of 305 cognitively normal; 475 patients with amnestic mild cognitive impairment (aMCI); and 162 patients with dementia were included in this study. We compared the performance of 3 different methods in predicting progression from aMCI to dementia: (1) index-based model; (2) logistic regression (LR); and (3) ensemble linear discriminant (ELD) machine learning models. LR and ELD models were trained using data from cognitively normal and dementia subgroups, and subsequently were applied to aMCI subgroup to predict their disease progression. Results: Performance of ELD models were better than LR models in prediction of conversion from aMCI to Alzheimer dementia at all time frames. ELD models performed better when a larger number of features were used for prediction. Conclusion: Machine learning models have substantial potential to improve the predictive ability for cognitive outcomes.

We have developed an experimental approach that allows us to estimate the performance of a large-scale enterprise network to update routing information. This approach was applied to the integration of the UFJ Bank network system on January 15, 2002. The main characteristic of this approach is the application of a formula that represents the delays in updating routing information that accompany reductions in CPU resources. This procedure consists of two steps: one is to estimate the reduction in the availability of CPU resources caused by forwarding of data packets at a router, and the other is to estimate the levels of CPU resources required for replying to a query about a new route and subsequently updating the routing information. These steps were applied to estimate the performance of the network in terms of routing information convergence. The results of our experiments on the network showed that updating the routing information was possible as long as the average level of CPU utilization during any five-minute period at the routers was less than 40%. We were able to apply this guideline and thus confirm the stability of the UFJ Bank network.

might in time look draconian and misplaced?" (p. 113). (The same question could be asked about some of the papers in this volume that take on the "salvage" paradigm.) Her reflections on anthropologists' support for self-evident truths "at home" underscore the book's argument for more comparisons among national traditions. She concludes that while anthropological theory has moved in different directions in Canada and South Africa, the ideas in both countries have a disturbingly common basis in the attempt to classify human groups as enduring cultural categories. Dyck's paper builds on his ongoing ethnography of Canadian Indian administration policies in Canada and their relationship to anthropology. Anthropologists, he argues, must come to grips with and reform the institutions of research and administration that increasingly stipulate the kinds of research we should do and then monitor our work. He points specifically to contradictions in the Canadian Social Sciences and Humanities Research Council (SSHRC) 2002–3 Dialogue on Research and Aboriginal Peoples and especially to the council's proposal to give aboriginal scholars and elders a decisive role in determining who gets research funds not only for studies of aboriginal issues but for all SSHRC peer adjudication committees. Dyck questions this unashamed use of essentialist categories that would have administrators decide who is designated as "aboriginal" or as "scholar." His call for ethnographic investigation of practices whereby strategic control of research resources could devolve to a set of ethnically defined individuals underscores the same issue raised by Plaice in her paper. What interests are being served? How are anthropologists implicated? Why and how does an initiative to achieve control of the practice of scholarship become a matter of intense political contestation, causing anthropologists to submit to self-censorship and situational silence? And to what extent is this an ongoing legacy of Canadian Indian administration? My response to the book as a whole echoes Graburn's observation in his chapter describing his experiences working in Canada: only in hindsight do we realize what we have lived through. This volume raises provocative questions about diverse traditions in Canadian anthropology and about where we have come from and where we may be going.


The extracellular signal‐regulated kinase (ERK) pathway is vital to the regulation of a number of cellular processes, including cell growth, division and apoptosis. As breast cancers frequently demonstrate an increased activation of the ERK kinase pathway, we examined the ability of SU1498, a direct inhibitor of ERK kinase activity, to sensitize cells to apoptosis. Two breast cancer cell lines, MCF‐7 and MDA‐MB‐231, are examined under normal growth and serum starvation conditions. SU1498 inhibited growth and proliferation in treated cells under both conditions, and cell cycle analysis by flow cytometry indicated cell cycle arrest in treated cells. However, increased apoptosis as demonstrated by Annexin‐V staining occurred only with a combination of SU1498 and serum starvation. The expression levels of the Bcl‐2 protein family members were examined and antiapoptotic Bcl‐xL and Bcl‐2 were downregulated while proapoptotic Bik was upregulation. This study elucidates the importance of ERK activity in the regulation of apoptosis in breast cancer cells. The ability of SU1498 to sensitize breast cancer cells to apoptosis by inhibition of ERK suggests therapeutic uses.

of Thesis Presented to the Graduate School of the University of Florida in Partial Ful llment of the Requirements for the Degree of Master of Science EVENT DETECTION FOR SUPPORTING ACTIVE CAPABILITY IN AN OODBMS: SEMANTICS, ARCHITECTURE AND IMPLEMENTATION By Vidhya Krishnaprasad April 1994 Chairman: Dr. Sharma Chakravarthy Major Department: Computer and Information Sciences During the last decade, database management systems (DBMSs) have evolved considerably to meet the requirements of emerging applications. One of the requirements is to represent real-world situations as part of the database, and monitor and react to them automatically without user or application intervention. Making a database system active entails not only developing an expressive event speci cation language with well-de ned semantics and algorithms for the detection of composite events, but also an architecture for an event detector along with its implementation. This thesis extends earlier work on event speci cation language and provides the semantics of composite events over a global event-history (or a global event-log). Parameter contexts are re ned for meaningfully restricting the detection of composite events. In addition, algorithms for the detection of composite events in various parameter contexts are presented. We describe the implementation of the composite event detector and rule execution in the context of an object-oriented active DBMS. We propose extensions to the Open OODB Toolkit (from Texas Instruments, Dallas) for incorporating ECA rules and discuss the advantages of the proposed architecture. vii The functionality supported by our architecture is compared with other existing approaches and the possible extensions to our system are also discussed.


The spatial random-effects model is flexible in modeling spatial covariance functions, and is computationally efficient for spatial prediction via fixed rank kriging. However, the success of this model depends on an appropriate set of basis functions. In this research, we propose a class of basis functions extracted from thin-plate splines. These functions are ordered in terms of their degrees of smoothness with a higher-order function corresponding to larger-scale features and a lower-order one corresponding to smaller-scale details, leading to a parsimonious representation for a nonstationary spatial covariance function. Consequently, only a small to moderate number of functions are needed in a spatial random-effects model. The proposed class of basis functions has several advantages over commonly used ones. First, we do not need to concern about the allocation of the basis functions, but simply select the total number of functions corresponding to a resolution. Second, only a small number of basis functions is usually required, which facilitates computation. Third, estimation variability of model parameters can be considerably reduced, and hence more precise covariance function estimates can be obtained. Fourth, the proposed basis functions depend only on the data locations but not the measurements taken at those locations, and are applicable regardless of whether the data locations are sparse or irregularly spaced. In addition, we derive a simple close-form expression for the maximum likelihood estimates of model parameters in the spatial random-effects model. Some numerical examples are provided to demonstrate the effectiveness of the proposed method.


Abstract : A path between NO(+) and H(+)(H2O)2 is proposed that may be fast enough to satisfy ionospheric requirements at 80 km. The path consists of six steps. The cluster ion NO(+)(N2) is formed. N2 is replaced by CO2, CO2 is replaced by H2O; NO(+)(H2O) is presumed to undergo an ion-atom Interchange reaction with either OH or HO2 or both to form H(+)(H2O); The cluster ion H(+)(H2O)(N2) is formed; and N2 is replaced by H2O to form H(+)(H2O)2.

Simple expressions of activities, as functions of composition, were developed from structural models for some borosilicate melts. Their applicability was tested with data from the liquidus curves of phase diagrams. If the heat of fusion is known, a value of the activity-composition function can be calculated for each temperature of the liquidus curve. These values are compared with activities computed from the structural model. Calorimetric heats of fusion were available for the calcium borates studied. Experimental data from published phase diagrams for the systems Ca3(BO3)2–Ca2SiO4, Ca2B2O6–Ca2SiO4, Ca3(BO3)2–CaSiO3, Ca(BO2)–CaSiO3, Ca2B2O5–CaSiO3, CaSiO3–BaSiO3, and CaSiO3–K2SiO3 were used. Simple ionic models seemed to be applicable in most cases, except for melts of highly polymerized mixed ions (metaborate-metasilicate), for which the so-called "group" model appeared to be useful. A value for the heat of fusion of CaSiO3 was calculated from this work (13,200 cal. per mole).

The contents of macronutrients and medium nutrient elements of Newhall navel orange(Citrus sinensis Osbeck) trees on trifoliate orange(Poncirus trifoliate Raf.) rootstocks were investigated and analyzed,and 122 leaf samples were col-lected from 122 orchards in 8 counties in southern Jiangxi province of China.The results showed that the states of macro-ele-ments and medium elements in leaves were imbalance,and leaf N and K contents were very high,and leaf P and S contents were optimal.However,leaf Ca content was low,and leaf Mg was deficient.The contents of N,P,K,Ca,Mg and S were(3.12±0.22)%,(0.16±0.05)%,(2.10±0.28)%,(3.05±0.0.6)%,(0.20±0.08)% and(0.27±0.06)%,respectively.The or-chard percentage of leaf N and K contents in high range and above was 76.23% and 100%,respectively.The percentage of orchards with leaf P and S contents in optimum range was 92.62% and 86.89%,respectively.However,the orchards with leaf Ca contents in low and deficient range took 46.72% and 53.28%,respectively,and Mg content in deficient range was 87.70%.It was recommended that Ca and Mg fertilizer should be added,while the N,P and K fertilizer should be decreased in order to balance the nutrients in leaves.


Nasopharyngeal carcinoma is a unique disease entity among head and neck cancers due to its epidemiology and clinical behavior. Non-keratinizing or undifferentiated carcinoma is the most common histological type in endemic areas. Radiotherapy is the treatment for early-stage disease. With the widespread use of IMRT, loco-regional control has improved significantly in locally advanced diseases. But distant metastasis continues to be the most common pattern of failure. To address this issue, chemotherapy has been incorporated into radiotherapy in various settings; as concurrent, induction, and adjuvant. The initial trials of concurrent chemotherapy incorporated adjuvant chemotherapy also and the magnitude of benefit contributed by each treatment was not clear. Later trials proved that adjuvant chemotherapy was not beneficial. Induction chemotherapy when added to concurrent chemoradiation resulted in improvement in Failure Free Survival, Overall Survival, and Distant Metastasis Free Survival. Thus, induction chemotherapy followed by concurrent chemoradiation became the standard of care for locally advanced disease (stage III and IVA). The role of chemotherapy in stage II disease is still evolving. Metastatic nasopharyngeal carcinoma is treated by platinum doublet chemotherapy, Cisplatin-gemcitabine is the standard regimen.


In order to develop and utilize of medicinal Chrysanthemum morifoliumthe germplasm resources,as well as provide technical support for genetic diversity and molecular identification studies of medicinal Chrysanthemum morifolium,the SCoT( start codon targeted polymorphism)-PCR( polymerase chain reaction) system was established and optimized. In this research,the L25( 56) orthogonal design was applied to optimize the five factors( Taq DNA polymerase,Mg2 +,template DNA,dNTPs and primer concentrations) of SCoT-PCR amplification system at five concentration ration levels. The results of optimized system by both intuitive analysis and variance analysis were as follows: a total volume of 20 μL system including 10 ng template DNA,1. 5 U Taq DNA polymerase,0. 8 μmol·L-1primer,2. 0 mmol·L-1Mg2 +,0.2 mmol·L-1dNTPs. The effective degree of the factors on the SCoT reaction was in the order: Taq DNA polymerase primer dNTPs Mg2 + template DNA. The key factor affecting the SCoT-PCR system was the concentration of Taq DNA polymerase. Furthermore,the optimal reaction system was further used to verify with multiple medicinal Chrysanthemum morifolium varieties,which showed good stability and repeatability. Our results indicate the SCoT-PCR system is informative and would facilitate further lay the solid foundation for genetic diversity,genetic maps,gene localizations and molecular marker assisted breeding studies in medicinal Chrysanthemum morifolium.


An unsettled question in attachment theory and research is the extent to which children's attachment patterns with mothers and fathers jointly predict developmental outcomes. In this study, we used individual participant data meta-analysis to assess whether early attachment networks with mothers and fathers are associated with children's internalizing and externalizing symptoms. Following a pre-registered protocol, data from 9 studies and 1,097 children (mean age: 28.67 months) with attachment classifications to both mothers and fathers were included in analyses. We used a linear mixed effects analysis to assess differences in children's internalizing and externalizing symptoms as assessed via the average of both maternal and paternal reports based on whether children had two, one, or no insecure (or disorganized) attachments. Results indicated that children with an insecure attachment relationship with one or both parents were at higher risk for elevated internalizing symptomatology compared with children who were securely attached to both parents. Children whose attachment relationships with both parents were classified as disorganized had more externalizing symptoms compared to children with either one or no disorganized attachment relationship with their parents. Across attachment classification networks and symptoms, findings suggest (a) a multiplicative effect when children have insecure or disorganized attachment to both parents, and (b) that mother-child and father-child attachment relationships may not differ in the roles they play in children's development of internalizing and externalizing symptoms.


Low-light visual perception, such as SLAM or SfM at night, has received increasing attention, in which keypoint detection and local feature description play an important role. Both handcraft designs and machine learning methods have been widely studied for local feature detection and description, however, the performance of existing methods degrades in the extreme low-light scenarios in a certain degree, due to the low signal-to-noise ratio in images. To address this challenge, images in RAW format that retain more raw sensing information have been considered in recent works with a denoise-then-detect scheme. However, existing denoising methods are still insufficient for RAW images and heavily time-consuming, which limits the practical applications of such scheme. In this paper, we propose DarkFeat, a deep learning model which directly detects and describes local features from extreme low-light RAW images in an end-to-end manner. A novel noise robustness map and selective suppression constraints are proposed to effectively mitigate the influence of noise and extract more reliable keypoints. Furthermore, a customized pipeline of synthesizing dataset containing low-light RAW image matching pairs is proposed to extend end-to-end training. Experimental results show that DarkFeat achieves state-of-the-art performance on both indoor and outdoor parts of the challenging MID benchmark, outperforms the denoise-then-detect methods and significantly reduces computational costs up to 70%. Code is available at https://github.com/THU-LYJ-Lab/DarkFeat.


The ILO (International labor standard) was enacted in order to improve the economic conditions of the labor class in various countries. The organization mainly covers four areas namely, child labor, right to the collective bargaining, forced labor and equality of opportunity. The author has confined her research by focusing only on one of the important aspects i.e. child labor. A child being the future of our country apposite care and concern is necessary towards them. The author has made an attempt to cover the causes, various international and Indian conventions primed to curb the social evil act of child labor. In order to cover the legal stand on the same, a brief idea has been given about the Articles of the Indian Constitution dealing with child labor followed by few landmark judgments and guidelines rendered by the Supreme Court of India. The article is concluded by the personal take of the author on the legislation and its enactments regarding child labor and with a few suggestions to improve the conditions of children in our country.

The PBF/LLR tests are designed to simulate the test conditions for the LOFT Power Ascension Tests L2-3 through L2-5. The test program has been designed to provide a parametric evaluation of the LOFT fuel (center and peripheral modules) over a wide range of power. This report presents the experiment predictions for the three four-rod LOCA tests.


Results from protein mutagenesis and x‐ray crystallographic studies of the multidomain protein Vascular Cell Adhesion Molecule (VCAM) were used to design cyclic octapeptides that retain the critical structural and binding elements of the epitope of VCAM in the interaction with the integrin α4β1 (VLA‐4). Changes in the activities of peptide analogues correlated with the relative activities of protein mutants of VCAM, and predicted the properties of two new mutants that bound α4β1 with improved affinity vs wild type protein. The nmr structures of two peptides revealed a high degree of similarity to the structure of the VCAM binding epitope. These results demonstrate that a compact binding epitope identified via protein structure–function studies may be transferred to a synthetically accessible small peptide with the key structure–activity relationships intact. © 1998 John Wiley & Sons, Inc.

The Reliance on Accounting Performance Measures concept (RAPM) was the object of numerous criticisms for a decade. Criticisms concern in particular the weakness of the theories which the RAPM is based on. The measurement of this paradigm was criticized; the main attention was to know if the study measured the same concept. Few qualitative researches were conducted to identify what the RAPM paradigm is. This exploratory study, based on 31 semi- directives interviews, try to identify what and how the RAPM appears and what kind on effects it produces on operational agent in public hospital.


Abstract: We show explicitly that Hertz equations and their extensions can be obtained from the non-relativistic limit of Lorentz transformation for Maxwell's equations. The explicit expression for the parameter α in the extended Hertz equations can be derived from such non-relativistic limit. We note that the Hertz equations should not be seen as a naive application of Galilean transformation to Maxwell's equations. The extended Hertz equations, which no longer preserve Galilean invariance, origin from Lorentz transformation of Maxwell's equations. Especially, the α parameter is of relativistic origin. Such equations, i.e., Hertz equations and their extensions, can be safely used when the electromagnetic field can be seen as the background. The superluminal behavior illustrated by the D'Alembert equation from the extended Hertz equations should be removed by including all of the subleading contributions in the v/c expansion. In the case that the electromagentic field is a background field, we need not worry about the apparent superluminal behavior of the D'Alembert equation. We should note that, to properly use the the Hertz and extend Hertz equations, the explicit forms of the functions for electromagnetic fields in the Hertz and extend Hertz equations should take an alternative forms ~ E and ~ B, which is just of form ~ E(Λ−1x) and ~ B(Λ−1x)) (or we need to use the inverse Galilean transformed forms ~ E[~z+~vz0, z0] , ~ B[~z+~vz0, z0] in the non-relativistic limit). Such a choice of descriptions are in general different to the ordinary one with ~ E(x) and ~ B(x), which can not be used in the Hertz and extended Hertz equations.


The t - J model has been intensively used in theoretical studies of d -wave superconductivity. However, it remains elusive whether such a simplified lattice model can ideally capture the exotic electron states, e.g., the d -wave superconductive (SC) dome and pseudogap (PG) normal state at finite temperature. Here we exploit the state-of-the-art thermal tensor network approach with implemented U(1) charge × SU(2) spin symmetry, to accurately simulate the temperature-doping phase diagram of the t - t (cid:48) - J model with both nearest-neighbor ( t ) and next-nearest-neighbor ( t (cid:48) ) hoppings. Below an onset temperature T ∗ c , we find the d -wave pairing susceptibility diverges as χ SC ∼ 1 /T α (with α (cid:39) 1 ). Remarkably, this SC onset temperature T ∗ c is found firstly enhanced and then decreased as the hole doping increases, giving rise to a dome-like structure. Near the optimal doping, it reaches the highest value of T ∗ c (cid:39) 0 . 05 t , implying a high-temperature SC in the 2D limit. Above T ∗ c yet below a much higher crossover temperature T ∗ , the magnetic susceptibility becomes suppressed, which resembles the PG behaviors observed in the underdoped cuprate superconductors. Our unbiased tensor network calculations bridge the gap between fundamental t - t (cid:48) - J model and cuprate superconductors from the finite-temperature perspective.


Preeclampsia (PE) is a pregnancy‐related hypertensive disorder, which may stem from impair placentation. Renin‐angiotensin system is one of the mediators of decidualization and trophoblastic proliferation. In the present study women with PE were studied in a comparison of normotensive controls to determine whether Angiotensin‐converting enzyme (ACE) gene I/D polymorphism affect the placental villi and umbilical cord formation with the assessment of biochemical and clinical risk factors.


In order to set up a new detection method for the compactness of highway subgrade,the subgrade deformation and mechanics mechanism under static penetration were discussed with the nonlinear variation characteristics of the subgrade soil deformation.The idea with step-loading and the layer-wise summation analysis of ground foundation settlement was introduced with the Duncan-Chang model and the incremental generalized Hooke's law.Therefore,an analysis model between the subgrade penetration load and its displacement with the parameters about initial porosity ratio,Poisson ratio,cohesive strength and angle of internal friction was developed.On the basis of the static penetration displacement analysis model mentioned above,a method of back analysis based on the adaptive genetic simulated-annealing algorithm was recommended according to the subgrade static penetration load and displacement test curves,then a new detection technique for the compactness of subgrade based on static penetration was set up,which can not only detect the compactness of subgrade,but also check the other physical and mechanical parameters of the subgrade soil.And it still has the features with fast and efficient detecting.Moreover,by comparison with the other existing methods and the computation of an engineering example,the proposed method was proved to be reasonable and feasible.


China's nuclear power standards have generally experienced three stages: starting, moderate development and rapid development. Up to now, a PWR nuclear power standard system with clear hierarchy, complete and reasonable structure and meeting the needs of the industry has been basically formed. This paper analyzes the conception, planning principles, main scope and objects, hierarchical structure, project setting and evolution process of China's nuclear power standard system. Finally, it briefly analyzes the characteristics and current situation of nuclear power standards in the United States and France, and expounds the differences in standardization mechanism and standard technology between the two countries and China.

Orbital angular momentum (OAM) is a physical quantity of an electromagnetic wave which is independent of polarization, and the electromagnetic wave having the OAM becomes a helical wave. A mode of the OAM can be defined according to the number of turns of helix per wavelength distance, and the different modes are mutually orthogonal. In recent years, with growth of the millimeter wave technology and demands for further high-speed large capacity transmission, a new spatial multiplexing transmission scheme using the orthogonality of OAM has attracted attention. In this paper, the impact of the ground reflected wave were evaluated by comparing the characteristics of OAM mode multiplexing and eigenbeam-space division multiplexing. As a result, it is found that the inter-mode interference due to the ground reflected wave is not so large and can be reduced with a small amount of degradation.


Haemangiopericytomas are uncommon vascular tumours found in almost every region of the body. The common sites are the soft tissues of limbs and head and neck. The incidence in head and neck ranges from 15 to 25% of all haemangiopericytomas. The uncertainty of the tumours is because of difficult histopathological nature and unpredictable biological behaviour. Its origin from the pericytes was described earlier by Stout and Murray who described these tumours clinically to be originating from the pericytes.


BACKGROUND The assessment of relationship quality is a key construct in family research and relies on several indicators. As answer behavior for sensitive and subjective questions can be biased by the interview situation, the emerging switch from face-to-face mode to web or mixed mode in surveys challenges the comparability of measurements. OBJECTIVE This study investigates the impact of two modes of data collection – face-to-face mode and web mode – on central measurements of relationship quality in quantitative family research. METHODS In a German experimental pilot study (2018) within the Generations and Gender Programme, target persons were randomly assigned to face-to-face or online interviews. Mode differences are assessed by comparing distributions for various indicators of relationship quality. To adjust for confounders, post-stratification weighting and multivariate regression analysis are applied.


The investigation of microbial life and/or inorganic biosignatures on Mars has been done mainly by the study of analogue environments on Earth. The nature of the ferriferous regions in Brazil seems to be suitable, as a substantial sources of extremophiles (Duarte et al. 2012; Camêlo et al. 2018) and potential source of inorganic biosignatures. This work is aimed to improve the knowledge needed to test the possibility of present or evidence of past life on Mars by characterizing samples of the iron-rich soil of the region of Diamantina, located at the center of Brazil. This characterization consists of examining the atomic and molecular compositions and the structural, mechanical and optical properties of the soil. This is done by applying different experimental techniques, such as thermo-gravimetry and X-ray spectroscopy. The molecular and atomic structure had been measured through, both, X-ray diffraction and fluorescence at LNLS (Brazilian Synchrotron Light Laboratory Campinas). Also, the volatile content was investigated through thermo-gravimetry in a high-temperature furnace. The sample of soil was extracted from region nearby the Red river, at the city of Diamantina MG, Brazil. In the present work, we show the results of three different techniques applied to examine the sample: X-ray powder diffraction, x-ray fluorescence, both measured in two beamlines at the LNLS, and thermo-gravimetry, at the chemical lab of the LNLS.


According to the problem that the positioning error increased with the increase of navigation time in the environment of complete lack of satellite signals such as viaduct and tunnel, the precise point positioning (PPP) / inertial navigation system (INS) tight coupled continuous positioning with non-holonomic constraint (NHC) and zero velocity update (ZUPT) in BeiDou navigation satellite system (BDS) was proposed. Firstly, the ionospheric composite model was analyzed from the aspects of observation equation, parameter estimation, fuzziness, degree of freedom and noise. The BDS PPP dynamic positioning model of ionospheric composite was established, and the errors that affect the positioning accuracy and convergence rate were analyzed. According to the motion characteristics of land vehicles, a scheme of velocity NHC was proposed to limit the accumulation of system positioning error with time, and ZUPT was used to increase the navigation accuracy of the integrated system when the vehicle was in the static state at the traffic light. The experimental results showed that the horizontal positioning accuracy of converged BDS PPP was better than 5 cm, the vertical positioning accuracy was better than 10 cm, and the dynamic positioning results are different from the high-precision real-time kinematic (RTK) / INS integrated navigation results by centimeters. The positioning accuracy of the system could be effectively improved by the BDS PPP/INS tight coupling method of NHC+ZUPT. Compared with the PPP/INS tight coupled positioning results without any constraints, the accuracy of the method in the three directions of East, North, and Up was increased by 0.08 m, 0.02 m and 0.01 m respectively.


A novel fault tolerant control scheme, using model-based control and time delay control theories, is proposed for flexible satellites with uncertainties and actuator saturation and the stability condition of the scheme is analysed. The moment–of-inertia uncertainty, actuator faults uncertainty, space environment disturbances and the actuator saturation are analysed. The computable control torques, including the space environmental torques, reaction wheel dynamics and the known flexible appendage dynamics, are formulated using the model-based control. The unknown flexible satellite dynamics is estimated according to its one-step previous value and employed to update the control command; this greatly reduces the conservativeness and enhances the pointing accuracy. Numerical simulations under different conditions demonstrate the advantages of the novel proposed controller compared to the conventional PD controller and a simplified fault tolerant controller.


Reinforced concrete (RC) structures are generally subjected to increasing loads, age-related deterioration and design changes that affect the integrity of structures. Therefore, this paper presents an experimental investigation of a carbon fibre reinforced polymer (CFRP) reinforced RC beam under three-point loading. Acoustic emission (AE) was used to monitor the progression of damage. The loading, AE intensity and AE signal strength were analysed and discussed. The analyses were performed using the AE signal collected from CH6 and CH7. The result is that crack nucleation produces high signal intensity compared to other crack modes. Moreover, the intensity plots fit the identified crack modes when the beams were reinforced with CFRP. Therefore, AE can be used to evaluate the performance of the CFRP reinforced RC beam.


Trace element water samples from KM1513 were collected with the MIT Automated Trace Element (ATE) sampler, deployed with a teflon-coated wire from the ship's deck for surface water samples (collected at roughly 10 m depth), and with the ATEs attached to PVC "Vanes" designed to prevent contamination from the ship's steel wire for samples collected at greater depth. Samples were filtered at 0.4 μm immediately after collection through polycarbonate track etched filters (Nucleopore) into 250 mL HDPE bottles and acidified to 0.012 M hydrochloric acid (ultrapure by quadruple distillation in a Vycor still; ~pH 2) at sea. Sampling and filtration followed published protocols used previously at Station ALOHA, for direct comparison (Fitzsimmons et al., 2015). These casts mostly aligned with Niskin cast station locations, but in some cases did not.

This research was developed in Mr. Alex Pucha´s, located in "El Pordel" neighborhood, Chuquiribamba parish, Loja province. The objectives were to evaluate the agronomic performance of two aromatic species, with three levels of organic fertilization and determine the acceptance and alternatives for commercialization of the two aromatic species. The vegetative material that was used for planting were cuttings which were very vigorous and healthy. The following aromatic species were evaluated Common mallow (CM) and rose essence (ER) with three levels of Organic fertilization (T0: Total Control; T1: 10 tn/ha bocashi; T2: 20 tn/ha bocashi; T3: 30 tn/ha bocashi) three levels of fertilization were distributed in a scheme of split plots in a randomized block design, with four replicas, in which fertilization levels correspond to the divided plots and at the same time these plots were split into two sub-plots which correspond to two species of Pelargonium evaluated. All variables were subjected to variance analysis and to the significance tests we applied Duncan multiple range to 5% of significance, to determine the differences between the averages of the factors and treatments.
The number of outbreaks was evaluated into 15 and 30 days, percentage of attaching and death, number of branches per plant, main stem diameter, days to physiological bloom, total plant height, biomass/plant/ ha yield, length and weight of root branching, dry matter yield/plant/ha and analysis of essential oils.
 From the analysis and interpretation of the results it was concluded: that variables (almost all) did not show significant differences as responses to organic fertilizer levels in the two aromatic species. However, treatment number 1 of Common Mallow, was the largest concentration of microbial population, this means that the total number of micro-organisms per gram of soil was of 18,666.667; resulting from this total the 5.36 % for fungi, 62.5% for bacteria and the 32,14% for actinomycetes, checking that the application of Bokashi which played a role in the development and growth of these organisms in the soil. The performance of biomass in the Rose essence species (Pelargonium graveolens L.), T2ER treatment turned out to be better, to which was applied 20 t/h Bokashi giving an average of 2055 kg /ha of dry matter with witness T0ER with 1656,2 kg/ha of dry matter. In the species Indian mallow (Pelargonium odoratissimum l.), the best treatment was the T2MO to which was applied 20 t/ha Bokashi , with a yield of 452,8 kg/ha of dry matter, against T0MO witness that reached 290,3 kg /ha. The application of organic fertilizers as the Bokashi, directly influenced the performance of aromatic study species since it improves the physical, chemical, and biological properties of the soil. Analysis of essential oil of Pelargonium graveolens L. has a bluish green color, stands out as a viscous liquid with a 0.45% of biomass yield and a density of 0.89 cm /g. In the same way for the essential oil of Pelargonium odoratissimum L. has a translucent yellow coloration, which is characterized as a viscous liquid with a 0.48% of biomass yield and a density of 0.90 cm/g.
According to tasting test, Common Mallow has more preference and acceptance. The market analysis carried out in the cantons of Catamayo, Loja and Paltas . It was determined that in Loja city, Common Mallow is consumed in second place, with respect to other aromatic plants. Meanwhile, rose essence is consumed in very little quantity and frequency, since they have no great introduction and acceptance in the market.


Abstract In this paper we present a forecasting method for time series using copula-based models for multivariate time series. We study how the performance of the predictions evolves when changing the strength of the different possible dependencies, as well as the structure of the dependence. We also look at the impact of the marginal distributions. The impact of estimation errors on the performance of the predictions is also considered. In all the experiments, we compare predictions from our multivariate method with predictions from the univariate version which has been introduced in the literature recently. To simplify implementation, a test of independence between univariate Markovian time series is proposed. Finally, we illustrate the methodology by a practical implementation with financial data.

An improved RRT* algorithm is proposed to solve the problems of poor goal orientation, low space utilization and many inflection points in the path planning of Automated Guided Vehicle (AGV) transportation. The algorithm adopts the approach sampling and restricted sampling strategies. First, the approach sampling method improves the sampling efficiency and reduces the path search time; then, the sampling area is reduced by limiting sampling, so as to improve the probability of sampling points falling in the path neighborhood and shorten the path length. On this basis, the redundant points of the path are trimmed according to the greedy algorithm, and the curvature of the path is optimized using the cubic B-spline smoothing method to obtain the driving track that meets the requirements of AGV running stability. Finally, through MATLAB simulation and comparative analysis, in the same environment, compared with the RRT* algorithm, the improved RRT* algorithm reduces the time of path search by 61.59% and the path length by 8.6%, which verifies the effectiveness of the improved RRT* algorithm.


Recent studies have shown that in LTE Uplink, the handshake procedure consisting of a scheduling request message from the User Equipment and a scheduling grant from the eNB required twice a communication over the air interface and caused notable delay. It could be harmful for loss and latency-sensitive applications such as Videotelephony traffics. So, we propose in this paper a new scheme which improves resource allocation for Videotelephony traffics and reduce the delay caused by Dynamic scheduling. The key idea is to schedule Videotelephony traffics using a Semi-Persistent strategy with Provisioning. The performance of our proposed algorithm have been evaluated in real LTE environments with LTE-Sim and simulations results demonstrated its effectiveness by showing that it optimized Videotelephony traffics performance and provided the best QoS support compared to the Dynamic Scheduling.


Abstract In addition to presenting personal contemplations on various topics, Rebekah Hyneman's prose and poetry has broader political and social agendas, namely bridging the gap between Jews and Gentiles. Hyneman felt that the Gentiles' lack of knowledge of Jewish traditions leads to estrangement between Jews and non-Jews. Nineteenth-century Jewish female writers, a religious and cultural minority within a minority (women writers in patriarchal society), have been misrepresented by their contemporaries. Modern critics have failed as well to relate to their distinctive contribution as Jews, and thus are held responsible for minimizing these writers' contribution to the nineteenth-century general effort. Rebekah Hyneman's "The Lost Diamond" (1862) is a case in point of a Jewish female writer who constructs multiple identities in her factual life, prose and poetry, none of which necessarily contradicts the other. Hyneman was at once a convert to Judaism and an opponent of intermarriage between Jews and Gentiles, a zealous American patriot, but one of the earliest Zionists, advocating the Jewish people's return to Jerusalem. She was a Jewish writer and poet, a "Mother in Israel," as I would like to call her, who concerned herself with Jewish traditions, and forced conversion to Christianity, and a writer who addressed the general public, especially female readership. Though far from being a feminist, one of Hyneman's major efforts was dedicated to the creation of a female "sweet communion," a sort of spiritual union of all women, that is, both Jewish and Gentiles.


The research article examines the features of the credit policy of a commercial bank. Credit policy contributes to the development of purchasing and investment capacity (is a source of investment) of individuals and legal entities, support of domestic producers. It is important for the banking system to develop a successful credit policy, which in turn covers the strategy and tactics of the bank to transfer the attracted resources to lend to the bank's clients. The conducted studies of credit relations indicate that the development of credit policy predetermines significant changes in the organization and functioning of business entities. A study of credit policy in the First Ukrainian International Bank (CB FUIB JSC) was carried out. Analyzed data on loans issued to customers of CB JSC "FUIB" during 2019-2020. The directions of increasing the efficiency of the formation of credit policy in CB FUIB JSC have been substantiated. To improve the efficiency of the credit policy of a commercial bank, in particular the timeliness of the application of funds / methods of monetary policy, and given the global scale and long-term nature of the crisis economic situation, it is advisable to improve the regulatory framework, including laws that protect the rights of creditors. In particular, to adopt the Law of Ukraine «About banks and banking activities», taking into account the objective laws of the functioning of the loan, the principles and conditions of the organization of lending, where to define both the responsibility of the bank and the borrower. It was revealed that it has a positive effect on increasing credit policy and reducing the interest rate. It is argued that the use of the main methods of managing the process of conducting credit operations of a bank can provide opportunities to significantly increase the efficiency of the functioning of banking institutions and intensify the credit process aimed at increasing investments in the real sector of the economy.
