Physical Human-Robot interaction (pHRi) is attracting an increasing interest in robotics research with a consequent fast progress in both methodological and technological aspects. Most of the results, however, deal with robotic manipulators and their application to humanoid robots is either not direct or poorly effective because they do not exploit the specificities of these robotic systems related to their mobility system. In addition, most humanoids are not equipped, for costs reasons, with the sensors commonly used in physical interaction, like, e.g., force sensors. In this work we propose a technique for guiding humanoids toward desired walking directions with a specified speed via physical interaction. The distinctive feature of the proposed method resides in the absence of any requirement to use force/torque sensors to measure the interaction forces. The considered physical interaction, herein referred to as manual guidance, includes both simple hand-in-hand guidance (see Fig. 1) and joint object transportation. Here we focus on hand-in-hand guidance. Manual guidance is usually obtained using force/torque sensors located at the humanoid's wrists [1]. These sensors are not part of the standard equipment and their inclusion increases both cost and complexity of the robotic platform. Developing minimal sensing approaches to physical interaction would at the same time overcome this problem and lay the basis for the exploration of new methodologies for pHRi especially suited to humanoid robots. The same minimalsensing spirit is behind the interaction behavior obtained with the Acroban robot in [2] which, however, relies on the dynamic peculiarities of a specific robot. Our method is equilibrium-based and uses the perceived perturbation of the Capture Point as a measure of the effect of interaction on the robot equilibrium. The concept of Capture Point (CP) was first introduced in [3]: the ability of a humanoid to cover a Capture Point with one of its feet is related to the possibility to come to a stop without falling. In this work, we propose an original use of the Capture Point concept. In manually guiding a humanoid the human is supposed to push or pull it toward some intended direction of motion. The humanoid center of mass (CoM) position and velocity will change accordingly. In particular, the position of the Capture Point, computed through the Linear Inverted Pendulum Model (LIPM) [3] and depending on these two quantities, moves in the same direction of the pushing or


parallel algorithms, data mining, data clustering, K-Means, K-Harmonic Means, Expectation Maximization, parallel, E.M As data collection increases at an accelerating rate with the advances of computers and networking technology, analyzing the data (data mining) becomes very important. Data clustering is one of the basic tools widely used as a component in many data mining solutions. Even though many data clustering algorithms have been developed in the last few decades, they face new challenges in front of huge data sets. Algorithms with quadratic (or higher order) computational complexity, like agglomerative algorithms, drop out very quickly. More efficient algorithms like K-Means and EM, which have linear cost per iteration, also need scale-up before they can be applied to very large data sets. This paper shows that many parameter estimation algorithms, including the clustering algorithms like K-Means, K-Harmonic Means and EM, have intrinsic parallel structure in them. Many workstations over a LAN or a multiple-processor computer can be efficiently used to run this class of algorithms in parallel. With 60 workstations running in parallel (on a fast LAN), clustering 28.8 GBytes of 40 dimensional data into 100 clusters, the utilization of the computing units is above 80%.


The Absorbing Aerosol Index (AAI) is a well-known measure of UV-absorbing aerosols. Important advantages of the method are that AAI can be retrieved in the presence of clouds, and that it is insensitive to surface type. Recently, a counterpart to the AAI was introduced: the Scattering Aerosol Index (SAI). The SAI is a measure of aerosols with a single scattering albedo larger than roughly 0.9. We present recent SAI and AAI results from SCIAMACHY, and show that a seasonal cycle can be observed not only for AAI, but also for SAI. We also show time series of monthly averaged Aerosol Indices in six selected regions. We compare these to cloud fractions (from the FRESCO+ algorithm) and to fire counts from (A)ATSR. AAI was found to correlate well with fire counts in three biomass burning regions, and characteristic seasonal dependences of both AAI and SAI were found for all six regions.


The main objects of study in this work are tensor networks. We study applications of these objects to problems in computer science and physics using methods from algebraic geometry, representation theory, and geometric invariant theory. The main results are: (1) Descriptions of several classes of tensor networks that can be efficiently contracted and some counting problems that they can model. (2) A classification of the invariant ring of a product of groups acting by conjugation, in particular the adjoint action of


Cytochrome c oxidase purified from the bacterium Paracoccus denitrificans was analyzed by analytical ultracentrifugation. In the detergent octyltetra/pentaoxyethylene (C8E45), the isolated enzyme exhibits a molecular weight of 79,000 to 84,000. The detergent-solubilized enzyme is thus a monomer which contains one copy of each of the two subunits.


The last few decades have been ones of complexity and contradiction. Long-term socio-economic restructuring has produced deep and growing wealth disparities, leveling great constraints on urban public schools that must confront the social and educational repercussions of chronic poverty. Long-standing political austerity, coupled with fallout from the great recession, has rendered private/corporate sector solutions to public problems increasingly expedient. Corporations have aggressively encroached into the gaps in provisions to public education, addressing problems that hyper-concentrated wealth has helped to engender. This literature review examines ideological debates surrounding one aspect of this shifting landscape: corporate philanthropic partnerships in education. Exploring research from education and business, this article rethinks the underlying assumptions, motivations, and implications of two bodies of literature and wider discourses that take counter-related positions on the role of corporate social participation: (a) public–private partnerships (PPPs) as manna and (b) PPPs as privatizations in education.


Topic modeling algorithms from the natural language processing (NLP) discipline have been used for various applications. For instance, topic modeling for the product recommendation systems in the e-commerce systems. In this paper, we briefly reviewed topic modeling applications and then described our proposed idea of utilizing topic modeling approaches for cyber threat intelligence (CTI) applications. We improved the previous work by implementing BERTopic and Top2Vec approaches, enabling users to select their preferred pre-trained text/sentence embedding model, and supporting various languages. We implemented our proposed idea as the new topic modeling module for the Open Web Application Security Project (OWASP) Maryam: Open-Source Intelligence (OSINT) framework. We also described our experiment results using a leaked hacker forum dataset (nulled.io) to attract more researchers and open-source communities to participate in the Maryam project of OWASP Foundation.


The clustering of web search has become a very interesting research area among academic and scientific communities involved in information retrieval. Clustering of web search result systems, also called Web Clustering Engines, seek to increase the coverage of documents presented for the user to review, while reducing the time spent reviewing them. Several algorithms for web document clustering already exist, but results show there is room for more to be done. This paper introduces a new description-centric algorithm for clustering of web results called IFCWR. IFCWR initially selects a maximum estimated number of clusters using Forgy's strategy, then it iteratively merges clusters until results cannot be improved. Every merge operation implies the execution of Fuzzy C-Means for clustering results of web search and the calculus of Bayesian Information Criterion for automatically evaluating the best solution and number of clusters. IFCWR was compared against other established web document clustering algorithms, among them: Suffix Tree Clustering and Lingo. Comparison was executed on AMBIENT and MORESQUE datasets, using precision, recall, f-measure, SSLk and other metrics. Results show a considerable improvement in clustering quality and performance.


Shepherd Steiner reflects upon the recent exhibition of Helen Frankenthaler's paintings at Gagosian Gallery, insisting that we disentangle criticism from the global circulation of art as finance capital.


We developed a 3D parallel full band Monte Carlo simulator for semiconductor devices. This enables us to simulate 3D devices on high performance multiprocessor machines. By utilizing the JASMIN [1] software package, parallel execution issues such as processors communication, grid partitioning and load balancing are handled easily and efficiently. The 3D MC simulator is validated by comparing its results with that from 2D 70nm SOI MOSFET simulations. We present speedup and load balancing results of our 3D simulator to show the parallel efficiency. A FinFet model [2], [3] is simulated for application.


The four workshop themes were: assessment practices, safety systems, best practices, and other road safety products and issues. The group of papers concerned with assessment practices explains the differences between the European Normative (EN) 1317 and the National Cooperative Highway Research Program (NCHRP) Report 350–AASHTO "Manual for Assessing Safety Hardware" (MASH) testing requirements and discusses solutions for further collaboration. The papers concerned with safety systems discuss various aspects of safety barriers, including their location and test speeds, and the elimination of noncrashworthy terminals. The third group of papers explain best practices, noting that one solution may not suit all practices in all countries. Examples of best practices in different countries are presented. Under the final theme, road safety products, the authors describe new products and treatments that may help to improve road safety, as well as the use of simulation models. Overall the papers presented at the workshop provide a comprehensive view of road safety engineering in Europe, the United States, and Australia. The papers have value beyond the meeting in Milan; they should have value to practitioners worldwide.


The characteristics of ganitri wood can be improved via wood impregnation. The objective of this research was to analyze the density and dimensional stability of a wood polymer nano-composite, i.e., impregnated ganitri wood with a mixture of melamine formaldehyde furfuryl alcohol and nano-SiO2. The results showed that the impregnation process improved the physical properties of the impregnated ganitri wood. Impregnation with 0.5% melamine-formaldehyde furfuryl alcohol (MFFA)-nano SiO2 had a significant effect on the density, weight percent gain, anti-swelling efficiency, bulking effect (BE), and water uptake (WU). Increased percentage of density and BE values after being treated by MFFA with 0.5% nano-SiO2 were 51.2% and 311.7%, respectively. The percentage decrease in WU was 47.5% (MFFA with 0.5% nano-SiO2). X-ray diffraction analysis verified a decrease in the crystallinity of the wood cellulose. The melamine formaldehyde furfuryl alcohol and nano-SiO2 polymers were found to cover the wood cell walls and lumens (based on scanning electron microscopy images). The formaldehyde emissions of the wood polymer nano-composite decreased. Therefore, it is possible to produce more environmentally friendly materials through wood polymer nano-composites.


Multi label classification has become a very important paradigm in the last few years because of the increasing domains that it can be applied to. Many researchers have developed many algorithms to solve the problem of multi label classification. Nerveless, there are still some stuck problems that need to be investigated in depth. The aim of this paper is to provide researchers with a brief introduction to the problem of multi label classification, and introduce some of the most trending challenges.


Relative rate constants for the addition of hydrogen atoms to fluorinated ethylenes, propenes and butenes have been determined by a competitive technique. Values relative to C2H4= 1.00 are C2H3F = 0.44, CH2CF2= 0.36, trans-CHFCHF = 0.09, cis-CHFCHF = 0.06, C2HF3= 0.05, C2F4= 0.08, CH2FCHCH2= 0.90, CH3CFCH2= 1.3, cis-CH3CHCHF = 0.16, trans-CH3 CHCHF = 0.50, CF3CHCH2= 0.40, CF3CFCF2 < 0.03, CH2FCH2CHCH2= 1.5, C2F5CHCH2= 0.48, CH3(CF3)CCH2= 1.1. In the case of the fluoroethylenes, the rate constants correlate qualitatively with minimum atom localisation energies if a term is included to allow for changes in charge density arising from fluorine substitution. In the case of the fluoro-propenes and -butenes, the introduction of fluorine into the molecule lowers its reactivity relative to the hydrocarbon olefin and this is discussed in terms of the (–I) and (+ M) effects. The results are consistent with an attack at a specific site via a σ-complex transition state.


This work evaluates the suitability of the finite difference methods and the pseudo-spectral methods for validating the pulse propagation problem in an optical fiber, which is modeled by the nonlinear Schrödinger equation (NLSE) represented in a classical electromagnetic version. In particular, the finite difference methods have been reported as excellent schemes for solving the nonlinear Schrödinger type-equations represented in multiple fields of study. However, a rigorous analysis of the finite difference methods for solving specifically the NLSE in fiber has not been reported yet. On the other hand, the pseudo-spectral methods are reported as optimal schemes to integrate the NLSE in fiber. Thus, four schemes of finite difference methods and three schemes of pseudo-spectral methods are analyzed by the validation of the propagation of a fundamental soliton, which demands a high level of convergence and stability to reproduce the complex behavior involved in this pulse propagation problem. As a result, we observe that the multiple phenomenologies modeled by the NLSE in fiber are reproduced numerically with the best degree of convergence and stability by the pseudo-spectral methods, whereas the finite difference methods are not suitable to validate this pulse propagation problem due to a loss of convergence and a high computational cost.


- Security aspects in this field which are remain at the core of interest. The aim of this research is to identify and solve the security issues related to the cloud computing. A detailed literature review is done to study the approaches and concepts used in the field of cryptography on cloud environment. In this work input is given by using Bench mark dataset and then key is created by using encryption algorithmRSA and MD5 then concatenate the keys. Optimize RSA algorithm is hybrid with MD5 to optimize the results. After this decryption process is also performed for decode the data. At last performance evaluation of the proposed system is done by using analysis of storage and time consumed during encryption and decryption process. The results show the attack is reduced by RSA approach with integrity MD5


According to the comparison of CR and DR in such aspects as principle analysis,main parameters,software operation capability and development prospects,along with our experience,it is concluded that CR is now fit for the middle and small hospitals as an expedient intergrading digital image equipment,while for the hospitals with workload of over 100 persons per day,DR should be the primary digital image equipment and CR should work as auxililiary digital image equipment.

Beam splitter is widely applied in many optical systems. The beam splitter is generally composed of many reflective mirrors and beam splitting prisms. The optical components can not reach the theoretical design state during assemble process. It must be solved through optical alignment. The mathematics model of alignment and error analysis for beam splitter are built in this paper. The effect of optical alignment error of beam splitter on optical system could be analyzed with this mathematical model. At the mean time, the mechanical alignment of beam splitter is directed to fast alignment in practical process. One kind of optical communication system is shown as example. The optical transmitting exit is commonly used. The requirement of axis parallelism of sub-systems is very strict. The axis parallelism between sub-systems reaches 5'' in experiment with this model application.


The spring lettuce crop in southern Texas is planted from late November to mid-December and harvested in March and April. This production period is dominated by 'Golden State D' and 'Valverde'. 'Val-Tex 54' and 'Val-Tex 5.5' were developed and selected for the semi-desert conditions that exist during this production period. Adaptation requires tolerance to occasional frosts in the seedling stage, heat tolerance at heading, slow bolting, and tipburn resistance. Resistance to downy mildew (Bremia lactucae Regl.), particularly races 5 and 6, is essential (Sleeth and Leeper, 1966; Jones and Leeper, 1971). The name Val-Tex indicates the Rio Grande Valley of Texas; 54 and 5.5 were incidental plot numbers.


One important recent application of image registration has been in the estimation of global motion parameters for object-based video coding. A limitation of current global motion estimation approaches is the additional complexity of the gradient-descent optimization that is typically required to calculate the optimal set of global motion parameters. In this paper we propose a new low-complexity algorithm for global motion estimation. The complexity of the proposed algorithm is reduced by performing the majority of the operations in the gradient-descent optimization using logic operations rather than full-precision arithmetic operations. This use of logic operations means that the algorithm can be implemented much more easily in hardware platforms such as field programmable gate arrays (FPGAs). Experimental results show that the execution time for software implementations of the new algorithm is reduced by a factor of almost four when compared to existing fast implementations without any significant loss in registration accuracy.


In experiments involving animals, it may be a difficult task for the experimenter to get homogeneous groups of animals. Blocking is commonly practiced to eliminate variability present in experimental material due to some known sources such as age, breed, housing condition, initial body weight, litter size, etc. When there are two noninteracting sources of variation in the experimental material, experimental designs under two-way blocking structure are advised. However, these designs are not appropriate when a third source of variability is present in theexperimental material as they may not be able to mark out the third features that tend to clump the animals into a third set of compact groups. Many times the clumps may be irregular, having no uniformity. In this paper, four methods of constructing designs under three way blocking structure for irregular clumps were developed in which two methods give designs with clumps having empty nodes. These designs assure more precise comparison among the treatments under study by removing three known sources of variability present in the experimental material.

The Pandemic from an Aesthetic Perspective—Towards a Beautiful Artistic Life in Difficult Situations
美学视角下的疫情——在困境中走向艺术化的美好生活
Abstract
The sudden outbreak of Covid-19 epidemic is an unprecedented battle for mankind, in which the sublimity and greatness of the human nature of medical workers in the frontlines from all countries is seen clearly from their brave devotion to the rescue of the infected. It is also an indication of the real concerns and attitudes as well as the abilities of the politicians of all countries in their dealing with emergencies. For most ordinary people, they also dramatized an interesting life play to the world. We are surprised to find out how much artistic people and people who are accompanied by art can bring to the world at this critical period of time. Their passion for artistic quality life has inspired countless lives. Art is not only the real record and representation of human history and life, sublimation of their spirit can also become a daily life mode of human beings, apart from the pursuit of materialism. At this special period when life is threatened by the virus, the desire of human beings to pursue and experience the spirit and even the spiritual space is becoming stronger and stronger. This disaster has brought us the opportunity of life reflection and the hope of rebirth. This paper tries to tell people that to live artistically while quarantining at home is not only what people at present are pursuing but also the long-term aspiration of life for the future.

Graphical comparative experimental data is presented showing the variation of the useful aperture diameter, directivity index, and beamwidth as a function of frequency for an acoustic lens alone and for an acoustic lens–acoustic filter plate combination. For the lens alone the aperture diameter is, of course, constant while the directivity index and beamwidth vary with frequency, but for the combined lens–filter plate device the effective aperture diameter varies with frequency while the directional parameters are effectively constant.


Autotetraploid cocksfoot(Dactylis glomerata) was obtained by chemical mutation of wild diploid cocksfoot in the west of China,and hybrid progeny of tetraploid hybrids were acquired from crosses between autotetraploids as female parent and wild tetraploids as male parent.The differences in morphological traits,growth and development,main agronomic characters among progeny,and of their parents showed that: 1) the average growing season of F1 hybrids was 208 d,39 days shorter than that of the male parents but 29 days longer than of the female parents;2) the average height of F1 hybrids 4 weeks after germination was 15.1 cm,65.9% taller than the female parents and 13.5% taller than the male parents.The growth of F2 plants in the seedling stage was similar to the F1;3) the average DM yields of F2 hybrids in the first growing period was 12.12 g/plant,lower than the male parents but markedly higher than the female parents(P0.01);4) among individual hybrid progeny, distinct difference existed in the seedling growth stage,tiller trait,regeneration,DM yields,reproductive performances,and disease resistance.Some hybrids had no distinct difference in DM yields,but were better than parents in early growth,reproductive character and disease resistance,so are propitious choices for breeding;5) hybrid progeny which have their parents morphological characters,and whose phonological development and tiller character are similar to their parents,are easily identified at an early growing stage,so the method of obtaining hybrid progenies from natural crossings can be used in breeding practice.


Creation of Yuefu poem in the early of Ming Dynasty integrated its own features with those of "school of Tieya Yuefu poem" represented by Yang Weizhen. The three creation trends are "Old Yuefu",palace lyrics,and the Yuefu before Tang Dynasty. The "Old Yuefu" in the early of Ming Dynasty was mainly the "Yang Weizhen's Old Yuefu"— "Old Yuefu" plus Yuefu before Tang Dynasty. Its two characteristics are as follows: 1) palace lyrics prevailed in the royal that time,due to the "Palace Lyrics Event",which was quite unique in the Yuefu creation; 2) the creation of Yuefu before Tang Dynasty was updated and allegorical.


The healthcare regulator has called for national standards for the time it should take for patients to receive results from radiology examinations after finding "significant variation" in reporting times across hospitals in England.

The Care Quality Commission (CQC) warned of delays to radiography results being shared with clinicians and of x ray films being examined by clinicians without specialist training in its report published on 19 July.1

The regulator said that it was concerned at the lack of agreed best practice and called for national standards for reporting turnaround times. It also called for …


The influence of temperature on the rheological properties and density of liquid egg product at pasteurization temperatures was investigated. the density of all these products decreased with increasing temperature: however, the changes were different depending on the product. the change in density may be represented by simple linear equations. All the products showed pseudoplastic flow behavior that may be described by the Power-law model. Egg white had the lowest power law index (n=0.552). Salted egg yolk had the highest n value (>0.8), thus it is closer to Newtonian fluid in its behavior. This index did not vary greatly with temperature for whole egg and egg white but decreased with temperature for egg yolk and salted egg yolk the lowest consistency coefficient (m=54.52mPa.sn) was observed for whole egg. Salted egg yolk had the highest m value (269.9mPa.sn). Them value increased with temperature for egg yolk and egg white, but decreased with temperature before showing an increase for salted egg yolk and egg white. the calculated Generalized Reynolds number was below 2100 for all the products. These results show that laminar flow exits during typical pasteurization of liquid egg products and therefore the minimum residence time is half the average resident time.


There is much interest in metamaterials for the microwave and optical applications because their electromagnetic properties are vastly different from ordinary materials. The split ring resonator (SRR) is the canonical metamaterial structure that has a magnetic response without magnetic materials. Magnetic properties of the SRR are considered as the substrate of the microstrip patch antenna instead of high permittivity materials because we can, not only reduce the size of the patch, but also improve the bandwidth of the antenna using high permeability materials for substrates of microstrip patch antennas. We also can design multi-band antennas using various kinds of microstructure in substrates.


Human kinases are a large family of proteins (500+) that catalyze ATP‐dependent phosphorylation of protein and metabolite substrates to regulate diverse facets of cell biology. Dysregulation and mutations of protein kinases are linked to human disease, providing opportunities for developing pharmacological agents as potential therapy. Assessing the selectivity of pharmacological compounds targeting this enzyme class is critical given that off‐target activity of kinase inhibitor drugs may result in toxicity. This set of protocols outlines use of ATP acyl phosphate activity–based probes to evaluate the potency and selectivity of kinase inhibitors via fluorescent gel– and mass spectrometry–based detection methods. These competitive chemical proteomic assays can evaluate engagement of >200 native kinase targets directly in complex proteomes. © 2019 by John Wiley & Sons, Inc.


In March-April 2021, the OPEC+ agreement continued to restrain growth in the extractive sector. Nevertheless, the trend component in the production dynamic demonstrated a positive trend on the back of an increased demand for coal and gas in the European and Asian markets. The trend component of production in the manufacturing sector also grew mainly owing to the increase in world prices for products from industries that take a significant share in the production structure (woodworking, metallurgy, chemistry). The current trends raise concerns about the potential acceleration of inflation.


Environmental impact assessment is one of the acceptable methods for achieving sustainable development. It is considered as a planning tool for managers and decision makers. Based on the potential effects that could occur as a result of project construction and development it is reasonable to eliminate or reduce the adverse effects. Today, the activities of the copper industry in providing the country's copper requirements and the growing importance of environmental compliance issues affecting various industries, especially the copper industry, make it necessary by the need for better and more efficient methods to identify and control the effects of the industrial complex activity. In this study, the environmental impacts of Sarcheshmeh Copper Complex were studied. In this regard, by use of experts opinion, and a check list for assessment of the environmental and socioeconomic factors that are affected by the project, the assessment data is gathered. Then, using rapid impact assessment matrix (RIAM) which weighted by ANP Method (Method AN-AM), and with the help of experts, the impact assessment were done. Results show that 12 environmental factors, and 3 social factors are moderate and less affected by the project and 5 socio-economic factors are benefited very positively by the project. As a result, given the strategic situation of the copper industry in the country and with the improvement plans and corrective options, continuation of the works of Sarcheshmeh Copper Project is suggested. Introduction Environmental impact assessment is a proper tool to ensure project implementation and it can be a way to specify, predict and interpret the social and environmental impacts of a proposed project's. Also considering environmental impact assessment is a systematic identification and evaluation of projects, programs and proposals on physical, biological, cultural and socio-economic elements of environment. its purpose is to ensure that all of the development options consistent with sustainable development and environmental impact at the design stage of any project should be identified and considered. Background of plans and projects in the country shows that in the past planning, like many developing countries, the importance and the value of natural resources and social environment are hidden from view of decision makers. Many of them without considering environmental and socio-economic considerations, design and exploitation have led to the consequences of such actions including incidence of pollution and resource degradation and social problems in a wide area of the country. However, in many areas of expertise, commitment to studies of impact assessment is not legitimacy in the national or international scale, but implementation and dedication to these issues in the deployment stage or implementation of systems have become integral part of these studies. Since the method of operation and management of multi-criteria model analysis of the environmental impacts assessment for industrial complexes projects have not been studied in a codified method, this research aims to propose a multi-criteria analysis to environmental impact assessment of industrial complexes in the country.

Objective To observe the points and effects of the trabeculectomy in primary angle-closure glaucoma(PACG) with persistent high intraocular pressure(IOP).Methods The trabeculectomy was performed on 22 eyes (21 cases) after the IOP and had been reduced with many kinds of methods in procedures ofpre-operation and intra-operation.Results The IOP was less than 21mmHg in 17 eyes without any antiglaucoma-drug and in 4 eyes with lower IOP drugs after 6-12 months of the operation.The visions of 19 eyes were raised.There were no serious complications.Conclusion Once the IOP cannot be controlled,surgical treatment should be undertaken at once.It is necessary and safe and effective to perform the trabeculectomy on PACG with persistent high IOP under careful preparing and operating and post-operation nursing.


The Sezary syndrome is a well defined clinical entity characterized by exfoliative erythroderma, generalized lymphadenopathy, pruritus, palmar plantar keratoderma, circulating malignant lymphocytes with a deeply-folded cerebrif̂ orm nucleus and a propensity to infiltrate the skin, and a chronic progressive clinical course. The morphology of the Sezary cell has been of great interest to those studying this disorder and its ultrastructural features described in detail. The advent of modern immunology has generated interest in the origin of this cell, which has the surface characteristics of a T lymphocyte, and its function. Broder and associates* studied seven patients with Sezary syndrome. Using an assortment of clever investigative manipulations, they have further defined the Sezary cell as a helper T lymphocyte capable of augmenting the synthesis of immunoglobulins by normal B lymphocytes as well as B lymphocytes from a patient with ataxia telangiectasia and Nezelof's syndrome* when co-cultured with these cells. The Sezary cells showed no suppressor activity on immunoglobulin synthesis when mixed with purified normal B cells. This paper presents convincing evidence that the neoplastic (leukemic) lymphocytes from the majority of patients with Sez?,ry syndrome originate from a subset of T helper lymphocytes. It further suggests that some humoral immunodeficiency syndromes, such as ataxia telangiectasia, and Nezelof's syndrome, may result from a deficiency of helper cells and not from an intrinsic defect of the B lymphocyte or excessive suppressor lymphocytes and may be treatable through replenishment of helper T cells or a humoral mediator produced by these cells.


A surface-mounted RF IC fabrication technology is presented that includes a substrate transfer processing step to glass. The fabrication technology uses copper in one of the last fabrication steps to form contacts and inductors. To demonstrate the technology, a differential varactorless 10 GHz LC oscillator is fabricated. The quality factor of the used 0.63 nH inductor is estimated by measuring the required start-up current of the oscillator. With a supply voltage of 3 V, the estimated quality factor is as high as 39 at 10 GHz. At 10 GHz the dissipation of the oscillator core is 0.42 mW (with 3 V supply voltage) and the measured phase noise better than -94.7 dBc/Hz at 1 MHz offset of the carrier. By increasing the bias current, the frequency can be tuned from 10.2 GHz to 8.7 GHz, which corresponds to a 15.8% tuning range. The proposed fabrication technology eliminates bond-wires, reduces cross-talk and yields excellent passives.


This article describes and analyses state behaviour in South Africa between 1910 and 1990 as reflected in its policing. Major changes are identified on the basis of a spectrum of behaviour: liberal, totalitarian, and authoritarian. What makes the South African case noteworthy is the simultaneous development of all three modes of policing. Although not the only causal factor, this was a consequence of a state which legislated a divided society into existance.


As many as four enzymes may be involved in the peptidoglycan crosslinking enzyme system in Streptomyces sp. [l]. Streptomyces K15 excretes an exocellular DD-carboxypeptidase ; it has two cell-bound DD-carboxypeptidases, one of which is released by protoplasting the mycelium whereas the other is bound to the plasma membrane; and finally it possesses a transpeptidase which is also membranebound, The enzyme system in Streptomyes R61 is very similar except for the membrane-bound DD-carboxypeptidase activity which is hardly detectable. Finally, the enzyme system in Streptomyces rimosus consists almost exclusively of a membrane-bound transpeptidase. Rabbits were immunized with the purified exocellular enzyme of Streptomjxes R61 and the antiserum thus obtained was used as a tool for the study of the relationship which might exist between these various enzymes. Two DD-carboxypeptidases unrelated to the preceding ones served as controls. One of them was the exocellular nn-carboxypeptidase from Actinomadura R39 [2,3]. I1 was selected because of the profound differences that occur in the type of interpeptide bridging in the wall peptidoglycans of the Streptomyces strains (a D-Ala-Gly-u-diaminopimelic acid linkage) and of Actinomadura R39 (a C-terminal D-Ala-(D)-meso-diaminopimelic acid linkage) [3 J. The other control en7yme was the exocellular DD-carboxypeptidase from Streptomyces albus G which, in contrast to the other Streptomyces exocellular DD-carboxypeptidases, is a cationic protein, does not perform transfer reactions, has a high lytic activity on various wall peptidoglycans and is largely insensitive to P-lactams [3].

Many historians have already discussed the propriety of using the words "early modern" in the periodization of non-European history1. In this paper I shall make a small suggestion concerning the usage of this notion in Ming-Qing history. This paper consists of three parts. In the first part, I shall make a brief survey on how the words "kinsei (in Japanese)" and "jinshi (in Chinese)" have been used to indicate the "modern" or "early modern" periods in East Asian historiography, and investigate the reason why these notions have been regarded as controversial or ambiguous by many historians. The historical trends of the East and Southeast Asian trading world during the sixteenth to eighteenth centuries will be outlined in the second part in order to show the common historical rhythm shared by most regions within this world. And in the last part, I shall discuss the possibilities and advantages of using the words "early modern" to show the common rhythm, common problems and different solutions seen in most parts of the world during this period.


The main protease (Mpro) of severe acute respiratory syndrome coronavirus (SARS CoV) is a key enzyme for viral replication, and is thus an attractive target for anti-SARS CoV drug development. Mpro belongs to the family of 3C-like cysteine proteases. The basic design of peptidomimetic inhibitors involved a warhead that can form covalent modifications to the –SH group of the active site residue Cys145 and a substrate peptide sequence that forms favourable interactions with the protease. We systematically profiled the substrate specificity of Mpro, which forms the basis of a rational design of peptidomimetic inhibitors.1 First, we created a library of protein-based substrates, and profiled the preference of amino acid residues at each of the P5 to P3' positions. Based on the substrate-specificity profile, we created 'superreactive' substrate sequences. In addition, a novel peptidomimetic inhibitor was synthesised using nitrile as the warhead.2 A number of inhibitors were synthesised to test the role of N-terminal protective groups and the substrate peptide sequences. Finally, the crystal structure of Mpro in complex with the best inhibitor was determined to provide a better understanding of protease-inhibitor interactions. The results on substrate specificity profile of Mpro have been reported.1 To profile the substratespecificity of the SARS-CoV Mpro, saturated mutagenesis was performed at each of the P5 to P3' positions of the WT auto-cleavage sequences Hong Kong Med J 2014;20(Suppl 4):S18-21 RFCID project number: 06060432 KB Wong *, DCC Wan, HF Chow


The wrinkle phenomenon often occurs during drawing of various thin-wall box container drawing parts,especially for stepped rectangular container and tapered square container. The cause of winkle has been analyzed and the solution for this kind of drawing parts has been obtained. The results show the wrinkle has direct relations with manufacturing parameters,assembly and debugging process of the die.


In this article, the non-equilibrium Green's function method developed by Keldysh[1] and Larkin-Ovchinnikov[2] is used to derive the expressions for quasi-particle and Josephson current of a superconducting junction under microwave irradiation. As an example, the results up to second order of irradiation field have been calculated. The influences of the microwave have been discussed briefly.


The coordinated effort of the immune system in host defense is dependent upon the proper release and interpretation of different cytokine signals. Several examples of monogenic diseases targeting the JAK-STAT pathway reveal there is still a critical need to understand basic principles of cytokine signaling and cytokine output. For example, patients with STAT1 gain-of-function (GOF) mutations exhibit a type 1/IFN-gamma bias that antagonizes a type 3/IL-17 immune response important for controlling fungal infection, yet patients also, paradoxically, exhibit chronic and sometimes lethal viral infections. Using a novel conditional knock in STAT1-GOF mouse model, we demonstrate that STAT1-GOF mice respond poorly to viral infections that are easily controlled by WT mice, such as MCMV and LCMV-Armstrong. High-dimensional flow cytometry and scRNA-seq reveal an impaired NK and CD8 T cell effector response in STAT1-GOF mice that is not simply due to an exhaustion phenotype. Instead, STAT1-GOF mice respond poorly to viral infections due to an unexpected defect in IFN-gamma production early during the innate immune response, leading to a cytokine storm, immunopathology, and an impaired adaptive immune response. scATAC/RNA-seq uncovers altered usage of different STAT complexes in STAT1-GOF mice, leading to a misinterpretation of early innate-stimulating cytokines. These results provide insight into why patients with interferonopathies or elevated interferons respond poorly to viral infections and highlight the importance of properly tuning STAT1 during an immune response.

Abstract. This study aimed to develop knowledge about the behavior of bent, multi-span sandwich panels. The analyzed panels have a soft polyisocyanurate foam core and rigid metal facings. The paper presents the results of experimental studies. The influence of support width, the span of the panel and purlin shape on the load-bearing capacity of the panel are analyzed. The tests carried out by the author have shown that not always the load capacity determined according to the standard is on the safe side. Therefore, the actual support conditions of the designed structure should always be taken into account.


Introduction

Water treadmill exercise is used for rehabilitating horses with back dysfunction, yet little is known about the effect of this type of exercise on back movement.

Methods

8 horses walked in water level with the hoof, fetlock, hock and stifle. Reflective markers over the dorsal spinous processes of T6, T10, T13, T18, L3, L5 and S3 and left and right tuber coxae were used to measure flexion-extension range of movement (F-E ROM) around T10, T13, T18, L3 and L5, vertical displacement of the pelvis (Pelvic ROM) and vertical distance between T13 and L5 (lowest and highest point of the back). 3D coordinates were tracked using ProReflex cameras. 5–9 strides were analysed for each horse at each water height. Repeated measures ANOVA and post hoc tests were used to determine differences in measured variables between water heights (P < 0.05).

Results

Peak flexion of T10, T13, T18 and L3 occurred in hock height water. Peak extension of T18, L3 and L5 occurred in stifle height water without a significant difference in F-E ROM between water heights (P>0.05). Pelvic ROM was greatest in stifle height water, with no significant difference between water heights. The vertical distance between T13 and L5 was greatest in stifle height water (P<0.05 between hoof and hock height water) as a result of an elevation of L5 relative to T13.

Conclusions

As water height increases L5 is elevated relative to T13, increasing the tendency for extension of the thoracolumbar spine. To maximise thoracolumbar flexion and avoid extension, water at hock height is more beneficial then stifle height water.

Power plant`s shutdown is a project that has a high degree of risk. Any risk of shutdown
will affect to the failure or delay of the shutdown project. Delays and project failures can lead to
plant shutdown costs are very high both because diesel costs and costs due to lost production.
RII (relative Importance Index) is calculated to obtain the value of likelihood, impact and
risk rating. Risk rating obtained from the multiplication of the likelihood and consequences of
each risk. The scales of 1 to 5 are given to the possibility and impact according to the PT NNT's
Risk Matrix.
Power Plant shutdown's variable risk in PT NNT divided into ten categories, there are:
cost risk, duration risk, safety risk, environmental/weather risk, the risk of sabotage, material and
equipment risk, resource risk, the risk of harm to the plant reliability, the risk of additional work
and changes in recent times risk.
The results showed that the risk on the turbine tasks and risk in running plant are risks
that have the highest rating. Mitigation plans implemented to reduce the risk rating using FGD
method, create STPs, bring in consultants, training of personnel, turbine life extentention study,
ensure the availability of recommended spare part, diesel plant in good condition are form of
controls to reduce the risk rating.


Because Kela 2 gas field is gas reservoir that has normal temperature and abnormal high pressure, it's better to use depletion production in gas recovery. By using perforation Completion, recommended design can product 10 billion cubic meter natural gas per year, with 4.25% velocity of gas recovery. Oil pipeline erosion, pipeline diameter optimization, completion pipeline design, production casing liner structure, wellhead tree and safe control system were discussed in this paper. The better designs of well completion and gas recovery were given in the paper, also.

The electron deficiency and strong bonding capacity of boron have led to a vast variety of molecular structures in chemistry and materials science. Here we report the observation of highly symmetric cobalt-centered boron drum-like structures of CoB 16 (cid:2) , characterized by photoelectron spectroscopy and ab initio calculations. The photoelectron spectra display a relatively simple spectral pattern, suggesting a high symmetry structure. Two nearly degenerate isomers with D 8d ( I ) and C 4v ( II ) symmetries are found computationally to compete for the global minimum. These drum-like structures consist of two B 8 rings sandwiching a cobalt atom, which has the highest coordination number known heretofore in chemistry. We show that doping of boron clusters with a transition metal atom induces an earlier two-dimensional to three-dimensional structural transition. The CoB 16 (cid:2) cluster is tested as a building block in a triple-decker sandwich, suggesting a promising route for its realization in the solid state. a supersonic expansion to form a collimated cluster for better and decelerated by in long resolution 2.5%, methods Search for the global minimum of CoB 16 (cid:2) was performed using the Coalescence Kick program 45 at the PBE0/3-21G level of theory 46,47 The Coalescence Kick algorithm generated B 10,000 trial structures for each spin multiplicity (singlet, triplet and quintet), followed by geometry optimization. Low-lying isomers within 25kcalmol (cid:2) 1 were further refined at a more expansive Def2-TZVP 48


A B S T R A C T The management of the SEACOOS program and its evolution over a five-year period are reviewed. The topics included pertain to the mechanisms used to create a consortium, define its mission, develop and manage its annual budget and tasking cycle; and the history of its focus over a five-year period. The management of SEACOOS was complex and required significant efforts to develop new approaches and collaborative mechanisms. Changes in management were made as weaknesses were identified and to enable a more unified ap proach to the evaluation, operations, data management and outreach efforts. A number of programmatic lessons learned are summarized that may be of value for future development of regional coastal ocean observing systems. of SEACOOS and its evolution over time are described. Another significant regional coastal ocean observing effort underway when SEACOOS began was the Gulf of Maine Ocean Observing System (GoMOOS, www.gomoos.org, Bogden and Richert, 2003). Good communication was established between the SEACOOS and GoMOOS programs, with strong collaboration on data management, but their program management approaches were quite different. GoMOOS had incorporated as a not-for-profit organization. It was focused on establishing and marketing a buoy-based observing program and viewed itself as a utility. GoMOOS also drew upon a history of regional collaboration that had not been established in the considerably larger four-state SEACOOS domain. Thus, the initial focus for SEACOOS was to foster collaboration between a number of existing sub-regional observing efforts.


Precise spatial and temporal manipulation of neural activity in specific genetically defined cell populations is now possible with the advent of optogenetics. The emerging field of optogenetics consists of a set of naturally-occurring and engineered light-sensitive membrane proteins that are able to activate (e.g. channelrhodopsin-2, ChR2) or silence (e.g. halorhodopsin, NpHR) neural activity. Here we demonstrate the technique and the feasibility of using novel adeno-associated viral (AAV) tools to activate (AAV-CaMKllα-ChR2-eYFP) or silence (AAV-CaMKllα-eNpHR3.0-eYFP) neural activity of rat prefrontal cortical prelimbic (PL) pyramidal neurons in vivo . In vivo single unit extracellular recording of ChR2-transduced pyramidal neurons showed that delivery of brief (10 ms) blue (473 nm) light-pulse trains up to 20 Hz via a custom fiber optic-coupled recording electrode (optrode) induced spiking with high fidelity at 20 Hz for the duration of recording (up to two hours in some cases). To silence spontaneously active neurons, we transduced them with the NpHR construct and administered continuous green (532 nm) light to completely inhibit action potential activity for up to 10 seconds with 100% fidelity in most cases. These versatile photosensitive tools, combined with optrode recording methods, provide experimental control over activity of genetically defined Overall, this is a well-executed study that fits the publication objectives of F1000Research . The authors report in vivo single unit recordings from cortical prelimbic pyramidal neurons expressing channelrhodopsin-2 or halorhodopsin. Although the basic premise of this article is not entirely novel and the authors refrain from arriving at any firm biological conclusions, the results raise some interesting issues. For instance, in Figure 1 and 2 channelrhodopsin-2 induced firing shows a rapid decrease in frequency (Figure 1b and 2c) which can elicit significant plasticity of the neurotransmitter release output of these neurons. Along the same lines in Figure 3, after 10 sec of green light exposure the firing frequency recovery shows significant rebound facilitation, which again could significantly impact neurotransmitter release output of these neurons. Therefore, in order to be able interpret the behavioral correlates of these activity patterns accurately, one would need to know the synaptic output properties of these neurons during and after optogenetic stimulation/silencing. This is a useful confirmation of the optogentic control of neural activity in the rat prefrontal cortex. The basic effectiveness and characterization of channel rhodopsin and halorhodopsin have been reported multiple times, so this study mainly extends the same findings to a new area of cortex in the anesthetized rat. The study design is straightforward, the results are well described, and the findings mainly solid. So, if novelty is a low priority and the hottest new technologies (in this case optical control) are the highest priority, I recommend publication. The authors should provide a more comprehensive report of previous findings in other preparations and compare results, particularly with regard to the rebound effects. Also, shouldn't they run a light only (no virus) control to show that light itself does not drive or inhibit neuronal activity? The distinction between phasic and not is fuzzy. What exactly is phasic about the phasic cells? They provide quantitative


Abstract A mathematical model for simulating the densification of bubbly glacier ice is used to interpret the following experimental data from the Vostok (central Antarctica) ice core: two ice-porosity profiles obtained by independent methods and a bubble-pressure profile obtained by direct measurements of air pressure within individual bubbles. The rheological properties of pure polycrystalline ice are deduced from the solution of the inverse problem. The model and the inferred ice-flow law are then validated, using porosity profiles from seven other ice cores drilled in Antarctica and Greenland, in the temperature range from -55° to -20° C. The following expression is adopted for the constitutive law: where ė and τ are the effective strain rate and stress, respectively, α is the creep exponent taken as 3.5, Rs is the gas constant and T(Ts) is the temperature (standard temperature). The numerical values obtained for the "linear" and "non-linear" viscosities are: μ1 = 2.9 ± 1.3 M Pa year and μ2 = 0.051 ± 0.019 M Paα year, and the apparent activation energy Q is confirmed to be 60 k J mole−1. The corresponding flow law is in good agreement with results of both mechanical tests and independent estimations based on the analysis of different natural phenomena associated with glacier-ice deformation. When the model is constrained by the porosity and bubble-pressure profiles from Vostok, the mean air content in Holocene ice is inferred to be about 0.088 cm3g−1. The corresponding mean air pressure in bubbles at the end of pore closure is about 0.083 M Pa, whereas the atmospheric pressure at this depth level would be 0.063 M Pa. The influence of the climatic change on the ice-porosity profile is discussed. It resulted in an increased air content in ice at Vostok during the Last Glacial Maximum: 0.096 cm3 g−1.


Background: Let-7c is a microRNA down-regulated in prostate cancer. Results: Let-7c suppresses androgen receptor expression by targeting its transcription via c-Myc. Suppression of AR by let-7c leads to decreased cell proliferation and tumor growth. Conclusion: Let-7c suppresses androgen receptor expression. Significance: Our study demonstrates that let-7c plays an important role in regulation of androgen signaling and prostate cancer proliferation. Castration-resistant prostate cancer continues to rely on androgen receptor (AR) expression. AR plays a central role in the development of prostate cancer and progression to castration resistance during and after androgen deprivation therapy. Here, we identified miR-let-7c as a key regulator of expression of AR. miR-let-7c suppresses AR expression and activity in human prostate cancer cells by targeting its transcription via c-Myc. Suppression of AR by let-7c leads to decreased cell proliferation of human prostate cancer cells. Down-regulation of Let-7c in prostate cancer specimens is inversely correlated with AR expression, whereas the expression of Lin28 (a repressor of let-7) is correlated positively with AR expression. Our study demonstrates that the miRNA let-7c plays an important role in the regulation of androgen signaling in prostate cancer by down-regulating AR expression. These results suggest that reconstitution of miR-let-7c may aid in targeting enhanced and hypersensitive AR in advanced prostate cancer.

ABSTRACT A sensitive enrichment method for the detection and quantification of 20 organophosphate pesticides in sea water and surface water was improved and validated. The compounds were extracted using ultrasound-assisted dispersive liquid–liquid microextraction and were analysed with an optimised Gas Chromatography - Tandem Quadrupole Mass Spectrometry (GC-MS/MS) method. Calibrations and validations were conducted for spiked local pond and Baltic Sea water. Recoveries of the organophosphate compounds from the different matrices ranged from about 25% to 70% and from 30% to 130% for pond and sea water, respectively. Obtained limit of detection (LoD) for both matrices was about 3 ng L−1 and the limit of quantification (k = 3) was 12 and 7 ng L−1 for pond and sea water, respectively. Valid extractability at the LoD level could be proven.


The presence of nanoparticles within the insulating matrix may improve some electrical, as well thermal, properties. In the present research it has been investigated the influence of graphene (G) nanoparticles in an epoxy matrix on the dielectric constant and on the DC conductivity. Several percentages of graphene nanoparticles have been employed, mostly below the percolation threshold. This choice is due to the fact that the goal is not to have a conductive material, but rather to control the dielectric properties with the percentage of nanoparticles. Similar studies have already been carried out starting from the reduction of graphene oxide (GO) 1-2 or


It is suggested that replication projects may be valuable in teaching research methods, and also address the current need in psychology for more independent verification of published studies. Their use in an undergraduate methods course is described, involving student teams who performed direct replications of four well–known experiments, yielding results which were subsequently published online. Illustrative data are given for the one successful replication and three failures obtained, and practical suggestions are given for incorporating replication projects intoa methods course as an alternative to the usual term project. It is also noted that the published success rates of replication attempts appear to be higher for those studies that were performed as class projects.

We have simulated the evolution of diploid, sexually reproducing populations using the Penna model of aging. We have noted that diminishing the recombination frequency during the gamete production generates a specific diversity of genomes in the populations. When two populations independently evolving for some time were mixed in one environmental niche of the limited size and crossbreeding between them was allowed, the average lifespan of hybrids was significantly shorter than the lifespan of the individuals of parental lines. Another effect of higher hybrid mortality is the faster elimination of one parental line from the shared environment. The two populations living in one environment co-exist much longer if they are genetically separated — they compete as two species instead of crossbreeding. This effect can be considered as the first step to speciation — any barrier eliminating crossbreeding between these populations, leading to speciation, would favor the populations.


This study advances the technology for "smart" antenna stents integrated with micro pressure sensors, targeting at providing a non-invasive and rapid diagnosis of stenting-induced complications in a wireless manner. The smart stent device is developed via considering both engineering and clinical practicality with enhanced electromechanical performance over reported counterparts. The fabricated prototypes are assembled on balloon catheters while withstanding crimping forces well greater than 100 N, and show wireless local pressure sensing with a resolution of 12.4 mmHg upon balloon expansion. Using a swine model, the device is successfully operated to demonstrate wireless detection of blood clot formation, as well as real-time tracking of blood pressure change over a mean arterial pressure of 108 mmHg.


Direct-Sequence Code Division Multiple Access (DS-CDMA) is a digital method to spread spectrum modulation for digital signal transmission. We propose to detect signal in DS-CDMA communication using the learning mechanism. Initially, the user signals are spread using the respective pseudo-noise (PN) code where the input signal is multiplied with the code which is then modulated using the quadrature phase shift keying (QPSK) modulator. The modulated signal is then transmitted in a 3G/4G channel considering all types of fading. The transmitted signal is received by the antenna array which is performed by demodulation. We propose to adaptively assign the weights by employing Improved Whale Optimized Multi-Layer Perceptron Neural Network (IWMLP-NN)-based learning mechanism. To design IWMLP-NN, Improved Whale Optimization Algorithm is combined with multilayer perceptron neural network. This is used instead of the normal Multiple Signal Classification (MUSIC) and least mean squares (LMS)/root-mean-square (RMS) algorithms used in beam-forming networks. After assigning weight through IWMLP-NN-based learning mechanism, we de-spread to get the original user data. We have compared our proposed technique with the normal techniques with the help of plots of Bit Error Rate (BER) versus Signal-to-Noise Ratio (SNR). We use both the AWGN channel and fading channel for analysis. Experimental results prove that our proposed method achieves better BER performance results even with deep fading.


Treatment of childhood asthma has not changed substantially in recent decades, with no truly new drugs having been introduced since the turn of the last century. Mainstream therapy consists largely of inhaled corticosteroids in combination with β-agonists. Montelukast has a role in treating viral-induced wheeze in younger children and in preventing exercise-induced asthma. Review of the currently registered clinical trials for childhood asthma does not reveal any exciting new drug prospects. In recognition of the generally poor adherence with asthma therapy, a substantial research effort is underway to test strategies designed to improve asthma management with existing medications. Novel drugs with potential activity in asthma are currently being trialled in adults with asthma and some of these may eventually find their way into paediatric use. However, themost exciting advances in childhood asthma are likely to come from trials designed to prevent asthma. While several potential strategies can be identified from epidemiological studies, well conducted randomised clinical trials will be required to determine whether they are effective.


Two young dogs, a Rottweiler and an Épagneul Breton, presented with chronic forelimb lameness. Orthopaedic examination confirmed the mild lameness and revealed pain on deep palpation at the palmar aspect of the 5th metacarpal. Radiographic evaluation revealed fracture of the 7th metacarpophalangeal sesamoid at the 5th metacarpophalangeal joint. Based on these findings, diagnosis of sesamoid disease was achieved. Both cases had been treated conservatively with restricted activity and anti-inflammatory drugs without any success. Then, resection of the affected sesamoid was performed. The outcome was good and the dogs were free of lameness 1 year post-operatively.


In a child with propionic acidemia, biochemical relapse associated with septicemia was successfully treated with peritoneal dialysis. It is suggested that this line of management is suitable for the management of biochemical crises in propionic acidemia.


The synthesis of two types of imidazole-based surfactants, [(ROCOCH2MIm)Br] and [(RNHCOCH2MIm)Br], of varying chain lengths (C10, C12 and C16), was conducted in the present work. The synthesis involves an initial reaction of bromoacetic acid with fatty alcohols or fatty amines, followed by quaternization with N-methyl imidazole. The micellar properties of all the synthesized compounds were determined using surface tensiometry and compared with [(RMIm)Br], a well-studied alkyl-substituted imidazole-based surfactant. Within the same homologous series, a decrease in critical micelle concentration (cmc) was observed with increasing alkyl chain length in all three types of cationic surfactants. Introduction of an ester [(ROCOCH2MIm)Br] or an amide group [(RNHCOCH2MIm)Br] in the alkyl chain lowers the cmc when compared to a cationic surfactant without functional group, [(RMIm)Br]. The synthesized surfactants were also assayed for antimicrobial activities and found to possess good activities against selected strains.


Abstract The generation of stationary Rossby waves by sources of potential vorticity in a westerly flow is examined here in the context of a two-layer, quasi-geostrophic, β-plane model. The response in each layer consists of a combination of a barotropic Rossby wave disturbance that extends far downstream of the source, and a baroclinic disturbance which is evanescent or wave-like in character, depending on the shear and degree of stratification. Contributions from each of these modes in each layer are strongly dependent on the basic flows in each layer; the degree of stratification; and the depths of the two layers. The lower layer response is dominated by an evanescent baroclinic mode when the upper layer westerlies are much larger than those in the lower layer. In this case, weak stationary Rossby waves of large wavelengths are confined to the upper layer and the disturbance in the lower layer is confined to the source region. Increasing the upper layer flow (with the lower layer flow fixed) increases ...

So in an effort to stop this I've done one thing and am trying a few new things:


In British Columbia, students with significant disabilities are often included in general education classes with their peers. Being fully included means students participate in the social and academic life of the classroom (Katz, 2012), but many students with significant disabilities are not fully participating at school (Kurth, Morningstar, & Kozleski, 2014; Sokal & Katz, 2015). The present study used a qualitative case study design to explore how a student with significant disabilities participates in an inclusive classroom. Using the Canadian Model of Occupational Performance and Engagement (CMOP-E) as a theoretical framework, interactions between factors of the person, environment, and the activity were explored (Polatajko, Townsend, & Craik, 2007). Results of this study suggest key factors that influence participation include: (a) student's ability to communicate; (b) classroom culture that respects diversity, fosters a sense of belonging and safety, and values personal and social responsibility; (c) access to adapted materials and Assistive Technology; (d) elements of Universal Design for Learning; (e) interactive learning; (f) weaving individualized learning outcomes into classroom activities and routines. Additional findings suggest that interactions of personal factors of all the members of the class influence participation, indicating the social environment must also be considered.


Experimental releases of 980 artificially-reared, individually-marked Cape teal (Anas capensis) were made during 1971 and 1972 near Velddrift, South Africa. All Cape teal in the release area were counted regularly at fortnightly intervals during 1972 - 1975. Comparisons between artificially-reared and wild birds provided information useful in evaluating the capacity of artificially-reared Cape teal to adapt to natural conditions. The mortality rate of artificially-reared birds was 0,60 per year, based on 41 recovery records. The birds' reproductive output was low during the first two years after release. Thereafter it improved considerably, although few of the released birds survived to this stage. In contrast with birds first released when fully-grown, birds released when 6 - 7 weeks old subsequently tended to return to the release site.


This paper (SPE 110628) was accepted for presentation at the SPE Annual Technical Conference and Exhibition, Anaheim, California, 11–14 November 2007, and revised for publication.

Summary We present laboratory experiments to investigate the influence of gravitational, viscous, and capillary effects on the CO2 injection process. Quasi 2D experiments are performed in a vertical glassbead pack in the parameter range of interest for CO2 sequestration in deep aquifers (i.e., with Bond numbers of approximately 10 and capillary numbers on the order of 10). The objective is to investigate the type of flow regimes that occur under favorable as well as unfavorable conditions of density and viscosity. The experiments demonstrate the existence of pore-scale instability in the presence of unfavorable gradients of viscosity and density. Consequently, conventional mathematical models may not be able to represent these unstable flows appropriately. A comparison with estimates from percolation theory shows reasonably good agreement with experimental observations.


This article investigates the policy of setting that is commonly being seen as an organizational tool for effective delivery of the National Literacy Strategy (NLS). It is suggested that teachers are finding the increased amount of whole-class teaching to a diverse range of abilities, as prescribed by the NLS, problematic. This case-study researches both teachers' and children's perspectives on the Literacy Hour as taught in mixed-ability classes and in sets. Reflective commentaries and pupil questionnaires were used to collect data over two years. The results indicate a complex range of issues, both pedagogical and organizational, which need be considered before setting can be promoted as a strategy for literacy delivery. I conclude that there is a need for urgent research into the effectiveness of setting as a means of teaching the Literacy Hour.


In this article, an adaptive integral sliding mode control scheme is addressed for switched non-linear systems in the presence of model uncertainties and external disturbances. The control law includes two parts: a slide mode controller for the reduced model of the plant and a compensation controller to deal with the non-linear systems with parameter uncertainties. The adaptive updated laws have been derived from the switched multiple Lyapunov function method, also an admissible switching signal with average dwell-time technique is given. The simplicity of the proposed control scheme facilitates its implementation and the overall control scheme guarantees the global asymptotic stability in the Lyapunov sense such that the sliding surface of the control system is well reached. Simulation results are presented to demonstrate the effectiveness and the feasibility of the proposed approach.


By simulation we got assessment of the potential effectiveness highlight the image of a remote object of unknown shape (space object) on black-and-white picture with using robust adaptive spatial-selective filter. It is assumed that the data processing is carried out in conditions of a priori uncertainty regarding the form of the space object and the probabilistic description of the background of the situation. Examples of image processing in natural conditions in operation at the object 3006, and evaluation of the use of algorithms.


Maritime container supply chains (MCSCs) is exposed to various risks arising from both internal operations and the external environment, and the increasing complexity of the modern global logistics system makes the situation even worse, thus causing a significant challenge to the effective risk management of MCSCs. However, systematic studies on this topic are relatively few. In view of this, this study aims to explore and analyse various MCSC risks, develop suitable risk assessment methods, and evaluate the overall performance of MCSCs from a systematic perspective, so as to ensure the safety, reliability, and resilience of MCSCs. This research starts with the identification and classification of all possible risk factors that may be involved in an MCSC based on a comprehensive literature review, and the research results are further validated through a Delphi expert survey. The identified risk factors are then analysed, screened, and assessed in detail. The novelty of this study lies not only on the risk assessment of MCSCs under an uncertain environment from a supply chain level but also on the consideration of the impact of risk condition of each individual MCSC on the overall performance of the entire container supply network. The research results will provide useful insights and valuable information for both researchers and practitioners on the risk analysis and assessment of MCSCs, which is beneficial to different types of stakeholders involved in the maritime shipping industry. The work is also able to provide a theoretical foundation for risk-based decision making and shipping route optimisation in further work. Although the risk assessment methods are presented on the basis of the specific context in MCSCs, it is believed that, with domain-specific knowledge and data, they can also be tailored for a wide range of applications to evaluate the reliability and performance of other supply chain systems, especially where a high level of uncertainty is involved.

This study was based on the case analysis that the ability and motivational concept of self formed from exhibition have affected the job involvement and job performance, because several companies have been held exhibition to their employee, sales-persons and distributors as the one of a means of profit seeking and social estimate. As the result of analysis, it was found that all three factors of ability (ability of job execution, consideration of value & moral principal, retention & manifestation of information & skill) formed from exhibition have affected the job involvement and job performance and all three factors of motivational concept of self(group efficacy, self efficacy and identification with the leader) formed from exhibition have affected the job involvement and job performance. And all three factors(job importance, job interest, job unification) of the job involvement formed from exhibition have affected job performance.


Teachers often consider modern active teaching methods to be better suited for students who are good at learning or even for gifted students, as they assume that students with learning disabilities have underdeveloped metacognitive and social learning skills, that they require more time to grasp the techniques of the more advanced, technology aided teaching methods and that they cannot acquire additional knowledge at the same time. Our research focuses on pupils with learning disabilities, their attitude towards learning and teaching with the help of ICT and on motivation that arises from it. The study has shown that students with learning disabilities are confident enough in their computer skills that teachers may freely use modern teaching methods with them in primary school, as even those children are motivated and have a good attitude towards such teaching methods.

The ultimate goal of vide compression is to maximize picture quality while minimizing bandwidth requirement. In most video storage and communication applications, the constraints are often expressed as limitation in delivery bandwidth or storage capacity. The objective of video encoder development is, therefore, to minimize the amount of distortions introduced by video compression and transmission. As an enabling technology, measurement of compression distortions and quality impact to end-users is crucial to video encoder optimization. While the field is developing quickly, there have been two different paradigms for video quality measurement that are being studied, picture quality models that use reference pictures, and the models that do not. An issue common to picture quality measurement in both paradigms is to obtain accurate measurement of picture distortions. In this paper, we review the requirements of these two measurement paradigms and propose two image analysis methods that address some specific issues of picture distortion measurement. First we describe a fast video alignment approach necessary for picture distortion measurement models that require references. In the rest of the paper, we propose a blur estimation scheme to measure blurring degradation introduced by video compression and imaging systems. We will then review its reference-free distortion measurement performance using data from two experiments.


This study aims to analyze the regulation and guarantee in the implementation ofinvestment in coastal areas and small islands by local governments as well as how tosupervise and control investment activities in coastal areas and small islands as well as theauthority of the Regional Government to stop and revoke the investment permit. Thenormative legal research method is used to examine in depth the regulation and guaranteeof the Regional Government in the implementation of investment in the coastal area ofNorth Sulawesi. In order to obtain data in this study, data collection techniques are neededto obtain primary data and secondary data, both of which will be analyzed. The datacollection technique used in this research is literature study. The result of the research showsthat the local government is still not optimal in the court of investment activities in theCoastal area of North Sulawesi. As a result of this, investment cases arise. The famous casesof investment in the Coastal Area are the Buyat Bay case or the coastal area pollution caseby PT Newmont Minahasa Raya, the iron ore exploration case on the North Minahasa islandof Bangka by PT MMP whose case went to the Supreme Court with the Supreme Courtdecision Number 255 of 2016 which won the community and revoke PT MMP's activities onthe island of Bangka. But until now the company has carried out its activities and thecommunity continues to struggle. The third case is PT MSM which, although it has beenrejected and dismissed by the North Sulawesi DPRD in 2016 but is still operating until nowIn investment activities in coastal areas, from these cases, the government tends to neglectand does not take action to stop the company's activities.
Keywords: Arrangement, guarantee, investment, coastal, small islands, North Sulawesi.


Polymerizations of styrene with azobisisobutyronitrile initiation or thermal initiation have been performed in the presence of dithiocarbamates with different N-groups, that is, benzyl 4,5-diphenyl-1H-imidazole-1-carbodithioate (2a), benzyl 1H-1,2,4-triazole-1-carbodithioate (2b), benzyl indole-1-carbodithioate (2c), benzyl 2-phenyl-indole-1-carbodithioate (2d), benzyl phenothiazine-10-carbodithioate (2e), benzyl 9H-carbazole-9-carbodithioate (2f), and benzyl dibenzo[b,f]azepine-5-carbodithioate (2g). The results show that the structure of the N-group of dithiocarbamates has significant effects on the activity of dithiocarbamates for the polymerization of styrene. 2a, 2b, 2c, 2d, and 2f are effective reversible addition–fragmentation chain transfer (RAFT) agents for the RAFT polymerization of styrene, and the polymerizations have good living characteristics. However, in the cases of 2e and 2g, the obtained polymers have uncontrolled molecular weights and broad molecular weight distributions. The polymerization rate is markedly influenced by the conjugation structure of the N-group of the dithiocarbamate, and the polymerization rate of 2b is greater than that of 2a. For 2b, the rate of polymerization seems independent of the RAFT agent concentration. However, a significant retardation in the rate of polymerization can be observed in the case of 2c. 2d is more effective than 2c, and the substitution group of phenyl on this dithiocarbamate has obvious effects on the effectiveness of the controlled polymerization of styrene. © 2005 Wiley Periodicals, Inc.

In this manuscript, I propose an alternative implementation of the Volcker Rule, Section 619 of the Dodd-Frank Wall Street Reform and Customer Protection Act of 2010. The Volcker Rule restricts the proprietary trading of U.S. banks and their affiliates to certain "client-oriented" activities, such as market making. Under my proposal, federal financial regulators would implement the Rule's "market-making-related activities" exemption to realize synergies with Dodd-Frank's initiatives in the area of swaps regulation and the regulation of over-the-counter markets. The manuscript draws upon the academic literature regarding expressive law, the history of federal banking legislation, and the text of the Dodd-Frank Act to argue that federal financial regulators have the discretion to implement the Rule's mandate in a manner that transcends the twin concerns of safety and soundness and mitigation of conflicts of interest. I further argue that such an implementation may well be essential to the vitality of the Volcker Rule, in light of the parsimonious implementation currently proposed by the federal financial regulators and the political forces aligned in favor of the Rule's repeal.


Based on Keller-Miksis model,the influences of multiple control parameters,such as acoustic pressure amplitude,acoustic frequency and bubble radius at rest,on the complicated dynamics characteristics of nonlinear bubble oscillation driven by acoustic wave are discussed by utilizing a variety of numerical analysis methods,and the restrictive relationships among different parameters are analyzed.It is shown that chaotic state can occur only in the condition of all of the parameters in the suitable threshold,as the same time,chaotic state is the result of interaction of multiple control parameters.Furthermore,the power spectral expansion and energy conversion are existed in this nonlinear system.It is certified that the stronger acoustic pressure amplitude,the greater the sub-harmonic energy,besides,the energy attenuation of fundamental harmonic is also much greater.


The divacancy (V2) is one of the fundamental defects in silicon. However, the interaction of V2 with hydrogen is still not fully understood. In the present work, deep level transient spectroscopy (DLTS) results on hydrogen-assisted annealing of V2 are presented. H+ ions were implanted with multiple energies into n-type Czochralski-grown samples, yielding uniform (box-like) concentration-versus-depth profiles of V2 and hydrogen in the region probed by the DLTS measurements. The evolution kinetics of V2 reveals two distinct processes: (i) a fast one attributed to dissociation of phosphorus-hydrogen pairs and reaction with highly mobile atomic Hi and (ii) a slow one whose origin is not identified yet. During the slow process, we observe the formation of a hydrogen-related electronic state, labeled E5* and positioned ∼0.42 eV below the conduction band edge. The growth of E5* displays a close one-to-one proportionality with the loss of a V2-related DLTS peak, presumably due to V2H, overlapping with that of the single negatively charged V2.The divacancy (V2) is one of the fundamental defects in silicon.

The T2 spectrum has been measured for different concentrations of fluorescent brightener agent solution with nuclear magnetic resonance( NMR) technology. The relationship between parameters of peak height、peak area and zenith time of the first peak and the concentration of fluorescent brightener are obtained. The results showed that there are no linear relationship between the concentration of the fluorescent brightener solution and the peak height,peak area of the first peak,but the zenith time of the first peak and the concentration of the fluorescent brightener solution has a linear relationship,so the zenith time of first peak of T2 spectrum can be regard as the sensitive parameter for the concentration of the fluorescent brightener fluorescent brightener solution,and a new method is given out for measuring the concentration of the fluorescent brightener agent solution using nuclear magnetic resonance technology by the parameter of the zenith time of first peak.

Learning community (LC) concepts were introduced to the Engineering Diploma program at NSAC during the past two years specifically in the first semester that the students are on campus. The approach allows faculty to integrate the course content of four courses through the medium of a design project which is assigned to teams of students. Emphasis is placed on scientific communication and the ability to work in teams towards a common goal, both being attributes which are deemed to be important by the engineering profession. Students are graded on this linked project for a contribution to the final grade in each of the participating courses. There is currently insufficient data to reliably judge the effect of this approach, but anecdotal evidence from the students indicates that it is popular and does contribute to the students' overall understanding and abilities.


The Complete Works of the Two-Ch'engs edited by their followers is the most important primary source in studying Ch'eng Hao's philosophy as well as his moral selfhood. Nevertheless, there are so many anonymous quotations in the book that it renders the study of Cheng Hao problematic. Huang Tsung-hsi did assign a chapter for Ch'eng Hao in his Scholarly Synopses of the Sung Yuan Confucians with sayings attributed to him. However, Huang did not state the criteria in selecting those quotations. In his classical work on Neo-Confucianism, The Substance of Mind and Nature. Professor Mou Tsung-san had succeeded in distinguishing Ch'eng Hao's sayings from that of his brother. Moreover, he stated clearly his principles of interpretation. Nevertheless, following the line of thought of Professor Mou, his scholarly research can still be supplemented. Inspired also by the concept of hermeneutical circle from the hermeneutics, the present essay attempts to achieve such a purpose by offering a three-step procedure with three principles of interpretation.
