The problem of biological damage of mineral building materials and structures based on them ismultifaceted and covers all types of industry. Themost destructive biocorrosion impacts are on building materials in cities with a large water area. Various types of microorganisms, including pathogens, and especially the filamentous fungi of the generaAspergillus,Penicillium,Trichoderma, etc., occupy the surfaces of mineral building materials, cause their destruction, disturb the ecological balance of cities and endanger the human health. The term 'sick building syndrome' (SBS) is used to describe a situation when the residents of a building experience acute healthor comfortrelated effects that seem to be linked directly to the time spent in the building wherein no specific illness or cause can be identified. Biological contaminants, in particular micromycetes, can present one of the possible causes of SBS. Here, we assessed the biodeterioration level of structural materials on the basis of fine-grained concrete widely used in construction practice and architecture. First, we determined the strength characteristics of the material that has been biologically damaged; second, we identified the damaging micromycetes and analysed their metabolic activity related both to the induction of biocorrosion and to the impacts of fungi on human health. Applying a new integrated approach, which combines methods of molecular microbiology and genetic toxicology with standard methods for determining the strength of building structures, we confirmed the relation between biodestructive and pathogenic properties of micromycete isolates.


The word 'diaspora' has been fashionable for the last twenty years, particularly in the Anglophone literature. But, as in history, the meaning of the word appeared diverse. This article describes the definitions of the diaspora since the 1980's. It discards the confuDenise Helly, ": un enjeu politique, un symbole, un concept?" (2006) 6 sion between diaspora and transnationalism easily induced by the economic globalisation and the easiness of communications. It also aims at discarding the confusion between diaspora and forced labour migrations reminding two primordial features of a diaspora in the modern ages: the risk for a population to be exposed to violence and expulsion, its ability to keep at bay the threat by maintaining a community organization through time and boundaries.

Abstract In this interview, Mark Gevisser reflects on the modes in which South Africa is considered progressive when it comes to LGBTQI rights and how it differs from the rest of Africa in this regard. Developing some of the most significant issues faced by LGBTQI people today, Gevisser considers the role of the South African constitution in the development of queer rights, activism against homophobia, the growth of trans rights, and the struggles faced by those seeking asylum in South Africa because of their sexual orientation or gender identity.


Objective: To investigate the significance of CD44v6 and FN expressions in hepatocellular carcinoma (HCC). Methods: EliVisionTM plus two-step immunohistochemical method was used to detect CD44v6 and FN expressions in 140 cases of HCC. Results: Positive expression rate of CD44v6 and FN in HCC were 42.9% and 35.7%, respectively. HCC with positive expression of CD44v6 had a higher metastatic rate (P < 0.05) and lower survival rate of 5 years (P < 0.05); HCC with positive FN expression had lower metastatic rate (P < 0.05) and higher survival rate of 5 years (P < 0.05). The expression of CD44v6 was negatively correlated to FN expression in HCC (r = −0.46). Conclusion: These results showed that the expressions of CD44v6 and FN were closely linked to potential metastasis and to the survival rate in HCC. CD44v6 and FN may be clinically used as prognostic indicators in HCC.


Interaction (or human-computer interaction/HCI) is a key ingredient of modern visualization and visual analysis systems. It allows the user to manage the data and to explore its different aspects, as well as to shape its visual representation and to observe it from different perspectives – ultimately to pursue the user's analytical goal. Yet, so far interaction is perceived from either of three different angles: through interaction activities (e.g., visualization tasks or input events), through interaction architectures (e.g., model-viewcontroller), or through interaction metaphors (e.g., direct manipulation). This 1/2-day tutorial for beginning audiences aims to bring these three perspectives on interaction together by first detailing the state-of-the-art for each of them and then putting them in the context of each other. This will be accompanied by a discussion of real world examples – i.e., actual interactive visualization techniques and systems – to highlight the benefits and challenges of such a comprehensive view on interaction. After completing this tutorial, participants can expect to have gained an extensive overview of interaction in visualization that will allow them to consider all three of the perspectives when designing and evaluating interactions. 1 TUTORIAL MOTIVATION While on the one hand it seems hard to overestimate interaction [10, 62], on the other hand a clear understanding of its inner functions remain a grand challenge in visualization [41, 56]. As a result of this standing challenge, there exist many interaction taxonomies, however there is no single agreed-upon reference model for the interaction process – a lack that is dealt with by the majority of publications on this subject in one of three ways: 1. Functionally through interaction activities that do not relate to an encompassing model of interaction, but are considered operations in their own right – e.g., data level tasks (annotate, filter, etc.) [14, 44] or hardware level events (pinch, click, etc.) [46, 53]. 2. Procedurally through interaction architectures that relate to a system's internal processing model as a proxy for describing interaction mechanisms – e.g., interaction pipelining approaches [29], multi-threaded event handling [38], or the model-view-controller (MVC) pattern [30]. 3. Figuratively through interaction metaphors that relate to a user's mental model as a proxy for describing interaction mechanisms – e.g., direct manipulation [49] or instrumental interaction [9]. All three of these perspectives are valid and valuable: An interaction designer would probably take on the figurative, user-centric view (the H in HCI), whereas a software engineer may rather think in terms of the procedural, system-centric view (the C in HCI), and a data analyst is most likely to perceive her task as a purely functional activity on the data that is invoked via input events (the I in HCI). Yet, in order to understand and describe interaction comprehensively, one needs to consider and to incorporate all three of these perspectives. This tutorial will enable its participants to do so. ∗e-mail: firstname.lastname@example.com †e-mail: tatiana.von firstname.lastname@example.com ‡e-mail: firstname.lastname@example.com 2 TUTORIAL CONTENTS To achieve this aim, we discuss the state-of-the-art in all three of these aspects, while at the same time taking a fresh look at each of them by step-wise putting them into the context of each other. This is done in a bottom-up manner starting with a first part about the interaction activities as the functional building blocks that constitute interaction on the different levels of detail (hardware level, data level). These interaction activities are put together in a second part on interaction architecture that describes their interplay in forming the flow of interaction. Finally, a third part on interaction metaphors and guidelines discusses which of the activities to use in concert with which architectures and processes, so that the resulting interaction with the visualization becomes fluent and coherent. These three parts of the tutorial are outlined in the following. 2.1 PART I: Interaction Activities Interaction activities are usually thought of as being hierarchically organized. Depending on the different levels of granularity and the extent of this hierarchy, it can stretch from high-level cognitive activities to low-level perceptions [47], or from tasks to events [24]. Most research has been conducted on tasks (annotate, filter, etc.) [14, 44] that are related to the visualized data they shall be performed on [50, 65], and on events (pinch, click, etc.) [46, 53] that relate to an input device they are performed with [17, 20]. As a result, many task taxonomies for specific data types exist – for example, for graphs [32], for time-varying data [2], and for timevarying graphs [1]. Concrete examples discussed in this part will include, but not be limited to the interactive visualizations mentioned in [64, Sec.4], as well as those shown in [60]. The hierarchical relation between the data-level tasks and the hardware-level events is apparent, as a task is triggered by or composed of a number of input events. Yet there is not only a hierarchical relation of these levels, but also a procedural one: the user (sender) having a data-level task in mind has to encode this task into a series of hardware-level events (signals) that are sent through a number of input devices (channels) to the computer (receiver). So by thinking about interaction in these terms, its correspondence to a communication process becomes apparent. We will use this analogy between interaction and communication to discuss the challenges of interaction design that stem from it: How to encode the huge number of possible tasks onto the limited set of possible input events? (complex UI + minimal interaction vs. minimal UI + complex interaction [31]) How to deal with noise in this communications process? (magnification lenses to enlarge a target area [39], snap to grid mechanisms [12], etc.) Why is it so hard to define standard interaction vocabularies? [22] And which endeavors have been made in this direction? [11] 2.2 PART II: Interaction Architecture Interaction architecture and process models describe how the interaction is processed by the system. This differs from a workflow that concatenates tasks into an interaction sequence, as it models the flow of interaction from input/action to output/reaction through the system, including any effects it has on the system. These models are either abstract, on the level of interaction logic or on the technical level of the software implementation that realizes the interaction logic. For example, the simple activity of selection alone can behave according to thousands of different selection logics [63]. On the level of interaction logic, approaches exist to model the interaction process using various notations, such as the Unified Modeling Language (UML), in particular Sequence Diagrams [36] or the User Action Notation (UAN) [26] in combination with Task Transition Diagrams (TTD) [52]. Numerous others are surveyed in [19]. As it has recently been shown by the multilevel interaction model [40], it is even possible to include the hierarchical nature of interaction activities (cf. Part I) in such process models, effectively partitioning it into several interconnected models: the goal model, the behavior model, and the operation model. For the domain of visualization, recent work aimed to integrate interaction into the wide-spread pipeline model for visualization [29]. On the level of software implementation, the processing of interaction is commonly captured by design patterns, such as the modelview-controller pattern [30] and/or the data-context-interaction paradigm [18]. To not only provide the prospect to interact, but also the actual ability to do so, architectures such as multi-threaded event handling [38] aim to ensure a system's reactiveness. While the software design patterns have been readily embraced by practitioners, their relation to and the benefits of the more formal models on the level of interaction logic often remain unclear [51]. Hence, we will discuss these relations and their benefits – including the need for an underlying model in order to capture interaction history and analytical provenance [37], as well as for dealing with issues of multitasking and interruption [35]. 2.3 PART III: Interaction Metaphors and Guidelines Interaction metaphors propose an understanding of interaction through a meaningful and non-technical model that can serve users and developers of interaction [28]. Using such a metaphor as a pointer towards which combination of actions and interaction logic will produce a coherent set of interactions, shaping the interaction space [48] in a way that "makes sense" to the user. Common examples include direct manipulation [49] that is performed immediately on the objects to be changed, and instrumental interaction [9] that is performed through an intermediate, such as a tool or an instrument. Lesser known metaphors are direct combination [27] and surface interaction [58]. Yet, it is neither always clear how to map all desired activities onto metaphors, nor how to map all functionality they suggest/demand onto the given interaction process architecture. Model-based approaches, such as [3], have been developed to aid in this mapping and to uncover mapping errors. As intuitive as metaphors are, as restricting they can be. Hence, often a number of interaction design guidelines are given instead to constrain the design of interaction in a way that also produces coherence and ease of use. Most common is the notion of "fluid" interaction [21] that minimizes interruptions (as discussed at the end of Part II) and aims to facilitate a distraction-free flow-like experience for the user [23]. These guidelines can also be thought of as a higher-level concept than concrete metapho


Even in the present times, there remains a role for augmentation cystoplasty, although its use has become less common due to other less invasive procedures such as intravesical injection of botulinum toxin A and neuromodulation. Ileocystoplasty is the most commonly performed bladder augmentation procedure because of the reconstructive urologist's familiarity with ileum and the ileum's ability to easily reach to the pelvis.


Three sets of polyoxometalate (POM)-based amphiphilic hybrid macromolecules with different rigidity in their organic tails are used as models to understand the effect of molecular rigidity on their possible self-recognition feature during self-assembly processes. Self-recognition was achieved in the mixed solution of two structurally similar, T-shaped rigid sphere-rod amphiphiles, with the hydrophilic clusters being Anderson (Anderson-TOF4 ) and Dawson (Dawson-TOF4 ), respectively. Anderson-TOF4 are observed to self-assemble into onion-like multilayer structures and Dawson-TOF4 forms multilayer vesicles. The self-assembly is controlled by the interdigitation of hydrophobic rods and the counterion-mediated attraction among charged hydrophilic inorganic clusters. When the hydrophobic blocks were less rigid, e.g., partially rigid polystyrene (PS) and fully flexible alkyl chains, self-recognition was not observed, attributing to the flexible conformation of hydrophobic molecules in the solvophobic domain. This study reveals that the self-recognition among amphiphiles can be achieved by the geometrical limitation of the supramolecular structure due to the rigidity of solvophobic domains.

Molana Anwar Shah Kashmiri was a reputed Muhaddith of sub-continent. Wide vision of study and strong memory were his unique qualities. His wothy students wrote his lectures and transferred them in the shapes of worthy books. His unique technique of the interpretation of Hadith can easily understand through these books. In this article, we will try to understand the concept of abrogation of Molana Anwar Shah Kashmiri. There is a variety of opinions of  abrogation among scholars, that's why the fluctuation have been occurred in the number of abrogated verses. Molana Anwar Shah has a stand on this issue that no verse is abrogated completely. It is possible that a verse can be abrogated for its some particles but it is still relevant it's some particles. He applied this approach on the interpretation of Hadith. In this article, a research study is being conducted on Molana's concept of abrogation and its effects on the interpretation of Hadith.


The arguments my critics produce have made me realise that I fail to stress sufficiently forcefully one crucial message of my paper. This message is that my 'methodology', older connotations of this term notwithstanding, only appraises fully articulated theories (or research programmes) but it presumes to give advice to the scientist neither about how to arrive at good theories nor even about which of two rival programmes he should work on.1 My 'methodological rules' explain the rationale of the acceptance of Einstein's theory over Newton's, but they neither command nor advise the scientist to work in the Einsteinian and not in the Newtonian research programme.


The Polydnaviruses are an insect DNA virus group. The segmented genome of a polydnavirus is located on the host wasp chromosome as a provirus. After replication, virions are delivered into the parasitized host, where their expression products play significant roles in specific processes of parasitism. However, little is known about how viral gene expression is controlled. In the present study, we tested whether different genes in a genome segment are expressed concomitantly. Cotesia plutellae bracovirus (CpBV) is a polydnavirus mutualistic to an endoparasitoid, Cotesia plutellae (Braconidae: Hymenoptera). Its circular genome segments in viral particles were captured by a transposon containing pUC origin sequence and replicated in Escherichia coli. CpBV‐S30 (23.5 kb), one of the large CpBV genome segments, was fully sequenced, and seven open reading frames (ORF) were predicted. We analyzed expression patterns of the seven ORF in the diamondback moth, Plutella xylostella, parasitized by C. plutellae. Transcription analyses indicated that all ORF of CpBV‐S30 in the parasitized P. xylostella were expressed from the first day of parasitization and then expression levels decreased over the period of parasitization, except for CpBV‐H4, which showed an additional expression peak. In terms of tissue specificity in their expression patterns, all ORF were found to be expressed in the fat body, hemocytes and gut of the parasitized host. Promoter sequence analysis showed that all seven ORF had typical promoter elements, including TATA binding sites, but promoter component numbers and kinds varied. These results suggest that genes in a genome segment of CpBV can differentially express in the parasitized host, presumably by their different promoter components.


Methods: Fifty-one patients were imaged with a simultaneous gated transmission-emission tomographic system. Each patient had biplane contrast ventriculography (CVG) performed within 90 days of the SPECT study. The tomographic data was acquired over 16 frames/cycle, 64x64 matrix, 6.3mm pixels, over 360 degrees for 16 minutes duration. Attenuation corrected (AC) emission images were reconstructed over 360 and 180(RAO-LPO) degree arcs using algorithms previously described. Uncorrected (NC) images were reconstructed (recon) over the same arcs using filtered backprojection. Both AC and NC images were filtered and resliced to provide short axis (SA) data sets. The SA data were input to 3D-MSPECT which computed left ventricular EF and volumes over the cardiac cycle. For comparison, EF values were also computed with the QGS program.


Given a large real symmetric, positive semidefinite matrix, the goal of this paper is to show how a numerical approximation of the von Neumann entropy of the matrix can be computed in an efficient way, without relying on matrix diagonalization. An application from quantum optics dealing with the entanglement between photons illustrates the new algorithm.

We demonstrate the equivalence of the light‐front, equal‐time and covariant formulations in meson‐baryon interactions. In particular, we discuss the self‐energy Σ of a nucleon dressed by pion loops with the pseudovector πNN coupling. It is shown that the leading nonanalytic behavior of Σ is equivalent whichever formulations are used for the derivation.


The politicalization of religion issues is the important factors to impact political integration of multi-ethnic countries.In Central Asia,the politicalization of religion issues becomes the primary performance of religious extremist forces' existence and action.Taking the religious extremism as the theoretical guidance,the religious extremist forces in Central Asia made a series of terrorist and separatist activities in order to affect the political integration of multi-ethnic countries in Central Asia.Stopping the terrorist and separatist activities of religious extremist forces is the realistic choice to achieve political integration of multi-ethnic countries in Central Asia.


The purpose of the present paper is to show a method of solution of the purely rolling oscillations of a rectangular wing in supersonic flow and to present some numerical results. From these results it is possible to construct vector diagrams of the rolling moments acting on wings of several aspect ratios (A.R. = 1//3, 1, 3, 5, and » ) at two Mach Numbers (M = 10/7, and 2) for a range of reduced frequencies (0 < kc ^ 2.0). Thence, it is found that the tips of a finite wing tend to produce two effects— namely, (1) to reduce the real part of the rolling moment vectors and (2) to shift the rolling moment vectors in the positive direction. I t is believed that these effects are of great importance for estimations of the damping in roll.


In the automotive field, high performance and high reliable electrical machines are required and an appropriate thermal management allows to fulfil such a demand. Thermal management is also crucial for enhancing the power density, while it can also be applied to preserve the winding insulation lifetime of the electrical motor. From this prospective, an advanced cooling method is presented, whose action focuses on the end-windings, since they are commonly identified as the machine hot-spot. The effectiveness of the proposed cooling method is experimentally proven and the benefits raising from its implementation are quantified in terms of both temperature reduction, as well as insulation lifetime extension. A permanent magnet synchronous machine, employing a conventional housing waterjacket is used as study-case.

Hepatic encephalopathy (HE) is a serious neurological complication of acute and chronic liver failure. Expression of the neurosteroid/bile acid receptor Takeda G protein‐coupled receptor 5 (TGR5) has been demonstrated in the brain and is thought to be neuroprotective. However, it is unknown how TGR5 signaling can influence the progression and associated neuroinflammation of HE. HE was induced in C57Bl/6 mice via intraperitoneal injection of azoxymethane (AOM) and tissue was collected throughout disease progression. TGR5 expression was elevated in the frontal cortex following AOM injection in mice. The cellular localization of TGR5 was found in both neurons and microglia in the cortex of C57Bl/6 mice. Central infusion of the TGR5 agonist, betulinic acid, prior to AOM injection delayed neurological decline, increased cortical cyclic adenosine monophosphate concentrations, reduced microglia activation and proliferation, and reduced proinflammatory cytokine production. Betulinic acid treatment in vitro reduced the neuronal expression of chemokine ligand 2, a chemokine previously demonstrated to contribute to HE pathogenesis. Lastly, treatment of the microglia cell line EOC‐20 with conditioned media from betulinic acid‐treated primary neurons decreased phagocytic activity and cytokine production. Together, these data identify that activation of TGR5, which is up‐regulated during HE, alleviates neuroinflammation and improves outcomes of AOM‐treated mice through neuron and microglia paracrine signaling.

Background and objectives: Ziziphora tenuior is considered as an appropriate protoscolicidal agent yet the mechanism of such effect is not known so far. The aim of this study was to evaluate the apoptotic effect of Z. tenuior extract on protoscolices of hydatid cyst. Methods: Protoscolices were collected aseptically and the Bradford test was employed to determine the number required for the experiments. Various concentrations of Z. tenuior extract (5, 50, and 100 mg/mL) was incubated with hydatid cyst protoscolices at 37 oC and 5% Co2 for 4 h. The apoptotic effect of Z. tenuior extract on hydatid cyst protoscolices and the evaluation of caspases 3, 8, and 9 activities were ditermined using ELISA-based commercial diagnostic kits. Results: In the present study, 50 and 100 mg/mL of Z. tenuior extract produced apoptosis in the protoscolices of hydatid cyst significantly (p<0.05). Also, the activity of caspase 3 at 50 and 100 mg/mL significantly increased by 29.99% and 36.01%, respectively (p<0.05). Similarly, caspase 9 also demonstrated a significant increased activity up to 15.23%, and 45.31% at the same concentrations used for caspase 3, respectively (p<0.05). Conclusion: Our findings in this study indicated that, Z. tenuior extract can induce apoptotic cell death on hydatid cyst protoscolices by increasing the activity of caspases 3 and 9 via the internal apoptotic pathway.


Driverdrowsiness is an important cause of traffic accidents. Many studies using computer vision techniques to detect driver drowsiness states, such as slow blinking, yawning, and nodding, have demonstrated excellent potential. Although existing studies have made significant progress, the number of samples in the training corpora is small, which makes it difficult for a model to learn effective drowsiness representations from images or videos. To address this issue, we develop an isotropic self-supervised learning (IsoSSL) approach to learn powerful representations of images without relying on human-provided annotations and propose an IsoSSL-MoCo model by combining IsoSSL with momentum contrast (MoCo). To exploit the complementarity of multimodal data, an attention-based multimodal fusion model is also proposed to fuse features from the eye, mouth, and optical flow of the head. Specifically, we first use the IsoSSL-MoCo model to pretrain the image encoders for the three modalities in other datasets. Then, these encoders are fine-tuned and integrated into the proposed fusion model. The feature vectors generated by the image encoders of the three modalities are fed into the recursive layer to extract temporal information. To capture the importance degrees of the effects of temporal features from the three modalities on drowsiness detection, an attention mechanism is introduced to automatically weigh the feature vectors from the recursive layer to improve detection accuracy. Finally, a vector representation is generated by the attention layer and is used to detect driver drowsiness states. Experimental results based on two challenging datasets show that our method outperforms the baseline methods and the latest existing methods.

A well-known feature of the ${\mathrm{CaFe}}_{2}{\mathrm{As}}_{2}$-based superconductors is the pressure-induced collapsed tetragonal phase that is commonly ascribed to the formation of an interlayer As--As bond. Using detailed x-ray scattering and spectroscopy, we find that Rh-doped ${\mathrm{Ca}}_{0.8}{\mathrm{Sr}}_{0.2}{\mathrm{Fe}}_{2}{\mathrm{As}}_{2}$ does not undergo a first-order phase transition and that local Fe moments persist despite the formation of interlayer As--As bonds. Our density functional theory calculations reveal that the Fe--As bond geometry is critical for stabilizing magnetism and the pressure-induced drop in the $c$ lattice parameter observed in pure ${\mathrm{CaFe}}_{2}{\mathrm{As}}_{2}$ is mostly due to a constriction within the FeAs planes. The collapsed tetragonal phase emerges when covalent bonding of strongly hybridized Fe $3d$ and As $4p$ states completely wins out over their exchange splitting. Thus the collapsed tetragonal phase is properly understood as a strong covalent phase that is fully nonmagnetic with the As--As bond forming as a by-product.


This project is based on the complete integration of a sludge dryer within the cement factory of Cemex España in Alicante (Spain). The overall benefits include the use of dried sewage sludge as a substitute fuel in the cement kiln while the quality of the cement is guaranteed, and a reliable end-use for the sludge, as well as energy self-sufficient and 0-odour sludge drying. The paper explains these benefits, including a special emphasis on the carbon footprint balance, the benefits of coupling several sectors of the industry and water management, and technical aspects of the integration process. The project was carried out by Aqualogy for the company CEMEX, within the framework of a collaboration agreement between the latter and the local water administration (Entidad de Sanejament de la Comunitat Valenciana). The plant was started-up on February 1st 2012, and the operation has been successful in terms of flexibility, drying performance, treatment capacity, odour control, and has demonstrated the feasibility of several innovative heat recovery features. This plant is now a key showcase for Aqualogy, as a differentiating reference as an expert low temperature dryer provider, able to comply with the client's specifications and concerns as well as contributing to climate change mitigation. Incorporating waste treatment processes in systems in which residual energy can be utilized is one of the best residue management alternatives. This project is an innovative showcase of thermal drying of sewage sludge, as it allows avoiding any use of primary energy consumption and the CO2 quota and optimizing its environmental footprint.


In 4], Keen and Series analysed the theory of pleating coordinates in the context of the Riley slice of Schottky space R, the deformation space of a genus two handlebody generated by two parabolics. This theory aims to give a complete description of the deformation space of a holomor-phic family of Kleinian groups in terms of the bending lamination of the convex hull boundary of the associated three manifold. In this note, we review the present status of the theory and discuss more carefully than in 4] the enumeration of the possible bending laminations for R, complicated in this case by the fact that the associated three manifold has compress-ible boundary. We correct two complementary errors in 4], which arose from subtleties of the enumeration, in particular showing that, contrary to the assertion made in 4], the pleating rays, namely the loci in R in which the projective measure class of the bending lamination is xed, have two connected components. In 4], L Keen and C Series used their theory of pleating invariants to study the so called Riley slice of Schottky space. The Riley slice is shown to be foliated by pleating rays on which the geometry of the limit set has xed combinatorial properties. There are two rather subtle errors in 4], concerning the labelling and connectivity of these rays. While the errors do not substantially aaect the main results, the correct picture illustrates the interesting new phenomenon that pleating varieties may not be connected, as well as some delicate points related to the marking of the group. The ideas involved will apply to other examples, and we consider them to be of suucient interest to be worth discussing at some length. Besides explaining and correcting the errors, we take the opportunity to review the background and discuss some of the techniques used in 4] in more detail.


Background One of the HAIs that often occurs is CAUTI, which is an infection that occurs as a result of catheter placement when the patient is admitted to a health facility. The role of nurses as providers of nursing care for patients who have catheters attached to prevent CAUTI is to perform urethral treatment. One of them uses Povidon Iodine 10% with Chlorhexidine 2%.


This paper intends to offer a new, positive conclusion on the ROK/U.S. Vietnam War alliance building on that of previous scholars.[1] South Korea made a strong impact on the war effort as an American ally fighting on their behalf, sending more than 300,000 troops and incurring 3,800 casualties. In return for sending troops, the ROK received numerous benefits, economically, militarily, and even politically. Despite these effects, the alliance agreements are often ignored in both American and international accounts of the ROK or Vietnam War. The few English secondary sources that do exist on the alliance tend to ignore the South Korean perspective or overemphasize South Korea's unfavorable position at the end of the war, when opportunities for bartering dried up. Thus, building on valuable portions of existing sources supplemented by a plethora of official U.S. documents, this research adds a new perspective to an understudied topic. Specifically, it reveals what previous scholarship has failed to properly recognize: Park Chung-hee made the most of the Vietnam War alliance.


Our main purpose is to prove the existence of a positive solution of the quasilinear second order elliptic differential equation (1) below in an exterior domain in Euclidean space Rn, n 3 2. More explicitly, if (1) has a positive subsolution w and a positive supersolution u such that W(X) < V(X) throughout an exterior domain G, (notation in Section 2), Theorem 3.3 establishes the existence of a solution u of (1) in G, such that w(x) < U(X) < a(z) for all x E G, . An analogous theorem for bounded domains due to Nagumo [7] is employed in Lemma 3.1 to construct a sequence of positive solutions of (1) in annular domains G(a, a + j), j = 1, 2 ,.... We then prove in Lemma 3.2 and Theorem 3.3 that this sequence converges to a positive solution of (1) in G, by means of interior Schauder estimates, D-space estimates, and a priori interior estimates on the gradient of a solution of (1) in a bounded domain. Theorem 3.3 is applied in Section 4 to give sufficient conditions for a quasilinear SchrBdinger equation (8) to have a solution in an exterior domain in Rn satisfying 0 < U(X) < 1 x 10, 4 = 2 n + E, for arbitrary E in (0, n 2), n 3 3; and a similar result is given for IZ = 2. Section 5 indicates the procedure for reduction of nonoscillation problems for (8) to corresponding problems for quasilinear ordinary differential equations or inequalities. In particular, criteria are given for the existence of a bounded positive solution of the generalized Emden-Fowler equation in some exterior domain. A necessary and sufficient

In this paper, we suggest a physical layer security transmission scheme which can be employed when an eavesdropper is located near a receiver and channels are correlated. When the receiver-eavesdropper distance is short, it is difficult to obtain a security gain because the eavesdropper can have a similar channel compared to the receiver. To mitigate this problem, the receiver may transmit a jamming signal to prevent data acquisition from the eavesdropper. On this occasion to lessen the outgoing interference caused by the jamming signal to external communication networks, we assume that the sum of the transmission power of the transmitter and the jamming power of the receiver is kept constant. Under this restricted power consumption condition, we evaluate the security performance of our proposed transmission scheme using two metrics, such as threshold outage probability and secrecy capacity. By simulation, we find the optimal power consumption ratio between transmission power and jamming power which maximizes the threshold outage probability. We also analyze the secrecy capacity by simulation and numerical results.

The aim of this research is to improve student learning outcomes in class III science subjects at SD Negeri 115/IX Niaso . This research is classroom action research which was carried out in two cycles with each cycle consisting of three meetings from the aspects of planning, action, observation and reflection. The subjects of this research were class III students at SD Negeri 115/IX Niaso in science subject in academic year 2021/2022, there were 27 students, consisting of 14 male students and 13 female students. Data collection techniques were carried out using (post-test), observation sheets and documentation. The analysis techniques used are qualitative and quantitative. Qualitative data through observations during the learning process such as observation sheets, teacher and student activities, and quantitative data through learning outcome tests. The results of this research show that student learning outcomes in cycle I were 51.85%. In cycle II there was an increase of 77.7% and had achieved 70% learning completeness at the end of the cycle. So it can be concluded that the Contextual Teaching and Learning (CTL) method can improve learning outcomes for students in class III science subjects at SD Negeri 115/IX Niaso .


Quantitative analysis of anatomical synaptic connectivity in microcircuits depends upon accurate three-dimensional (3D) reconstructions of synaptic ultrastructure using electron microscopy of serial ultrathin sections. Here we address two pitfalls in current methodology that lead to inaccurate reconstructions and compromise conclusions drawn from the data. The fi rst pitfall is inaccurate determination of ultrathin section thickness, which negatively affects the 3D shape of reconstructions and therefore impairs quantitative measurement of synaptic structures. Secondly, current methodology signifi cantly underestimates the number of synaptic junctions, with only two-thirds or less of genuine synaptic contacts being identifi ed in dendrites that radiate within the plane of section. Here we propose a new methodology utilizing precise optical measurements of section thickness and successive observations of synaptic elements across serial ultrathin sections that corrects for these limitations to allow accurate 3D reconstruction of synaptic ultrastructure. We use this methodology to reveal that parvalbumin-expressing cortical interneurons have a much higher synaptic density than previously shown. This result suggests that this technique will be useful for reexamining synaptic connectivity of other cell types. used to identify synapses include: (1) the existence of a parallel space about 20 nm wide between presynaptic and postsynaptic membranes, the so-called synaptic cleft, (2) the accumulation of small vesicles next to the presynaptic membrane in the presynap-tic bouton, and (3) specialization of presynaptic and postsynaptic membranes. The cleft can most easily be identifi ed when the section is cut perpendicular to the synaptic junction face, but its identifi ca-tion becomes much more diffi cult when sections are cut parallel to it. Here we introduce a new methodology that overcomes these limitations allowing accurate morphological reconstruction of neuronal tissue and identifi cation of synaptic contacts occurring at all angles relative to the plane of section. All experiments were conducted in compliance with the guidelines for animal experimentation of the Okazaki National Research Institutes. Three male Wistar rats (6 weeks of age, 140–160 g) were anes-thetized with an overdose of Nembutal and perfused through the heart with 10 ml of a solution of 250 mM sucrose, 5 mM MgCl 2 in 0.02 M phosphate buffer (PB; pH 7.4), followed by 300 ml of 4% paraformaldehyde containing 0.2% picric acid and 0.5% glu-taraldehyde in 0.1 M PB. Brains were then removed and oblique horizontal sections (50 µm thick) of frontal cortex were cut on a vibrating microtome (Leica VT1200S, Nussloch, Germany) along


The invention discloses an automatic focusing module at least comprising an installation pedestal, an electronically controlled zooming member, and at least one power transmission member. The installation pedestal at least is accommodated with a lens as well as the electronically controlled zooming member is assembled at one end of the installation pedestal. The electronically controlled zooming member and the lens are on a same optical axis. The power transmission member is buried in the installation pedestal as well as is respectively conducted with the electronically controlled zooming member and an external power supply. The electronically controlled zooming member obtains power supply by the power transmission member; and the curved surface of the electronically controlled zooming member is modulated by changing the power supply, so that an objective of automatic focusing is achieved. According to the automatic focusing module in the embodiment of the invention, the module part number is reduced so as to reduce costs; and because injection molding is realized after the power transmission part is buried in the focusing installation pedestal, the manufacturing technology of the module is easy. And moreover, not the whole power transmission member is exposed, so that it can be avoided that the power transmission member is contacted and conducted with other parts.


The role of the general practitioner in contraception is discussed. In the past contraception has not been part of the National Health Serv ice (NHS) and general practitioners (GPs) could only prescribe pills or appliances on a NHS prescription in cases of medical need. After April 1974 contraceptives will be placed on the same basis as other drugs and appliances under the NHS and medical reasons will no longer be required for their prescription. The attitude of the British Medical Association toward family planning has become very liberal as evidenced by the proposals made by the working group of the General Medical Services committee. There may be some problems for the GP in implementing the new proposals for most doctors have had little training in contraception in their undergraduate education. It would be quite wrong for GPs who are not interested or lack adequate knowledge to be persuaded to give family planning advice. It is doubtful whether many of even the specially-trained GPs will be able to give sufficient time to every woman in the practice requiring contraceptive advice. Patients already attending clinics may be encouraged to continue while the family doctor should concentrate on his patients who have been unwilling to seek advic e elsewhere.


The application of an imaging condition in wave equation shot profile migration is important to provide illumination compensation and amplitude recovery. Particularly for true-amplitude waveequation migration algorithms, a stable imaging condition is essential to successfully recover the medium reflectivity. We continue our study of a set of image conditions with illumination compensation by application to the Marmousi data. The imaging conditions are evaluated by the quality of the stacked migrated sections. The most stable of the tested imaging condition with illumination compensation divides the crosscorrelation of the upand downgoing wavefields by the autocorrelation of the downgoing wavefield. Smoothing imaging conditions, which work perfectly in vertically inhomogeneous media, tend to fail for laterally varying velocities.

The second positioning mechanism includes a nut that engages with the screw portion and is locked toward the first positioning mechanism. The coupling member includes a surrounding portion rotatably covering the bearing segment and having an inner friction surface that is in contact with an outer surface of the bearing segment to produce a first frictional force and two side friction surfaces that respectively abut against the first and second positioning mechanisms to produce second and third friction forces.


Indigenous species of earthworms (Family Megascolecidae) are widely distributed throughout the northern jarrah forest of Western Australia. They occur not at random, but in an aggregated pattern well described by a negative binomial. Earthworms are only active in the topsoil (to depth of 5.5 cm) when soil moisture (gravimetric) exceeds 4%. This occurs from May until November. The number of species occurring in jarrah forest at any place, and the frequency of occurrence, biomass and density of earthworms, vary with average annual rainfall. In the zone of highest rainfall six or seven species occur together, frequency of occurrence is 40-60%, and total biomass and total density do not exceed 8 g m-2 and 40 m-2 respectively, and generally average much less. In the lowest rainfall zone only one or two species occur in any one locality, with total density much less than 10 m-2. Multiple regression analyses between four earthworm variables and 20 site and soil characteristics were highly successful in that up to three predictor variables yielded coefficients of determination exceeding 0.70. The most useful predictor variables were rainfall zone, forest basal area, soil pH and proportion of silt and clay in the topsoil (to depth of 15 cm). Recurrent low intensity (spring) fires and a single moderate intensity fire (summer) have minor direct and indirect effects on earthworms. Logging also has scant effect on their frequency of occurrence. The land use most adverse to earthworms is the clearing of forest for mining of bauxite or gravel. The effect on earthworms of clearing of forest and subsequent reforestation with pines varies: in one case there was an adverse effect, whereas in two others there was no difference.


The massive deployment of Internet of Things (IoT) devices, including sensors and actuators, is ushering in smart and connected communities of the future. The massive deployment of IoT devices, including sensors and actuators, is ushering in smart and connected communities of the future. The availability of real-time and high-quality sensor data is crucial for various IoT applications, particularly in healthcare, energy, transportation, etc. However, data collection may have to be outsourced to external service providers (SPs) due to cost considerations or lack of specialized equipment. Hence, the data market plays a critical role in such scenarios where SPs have different quality levels of available data, and IoT users have different application-specific data needs. The pairing between data available to the SP and users in the data market requires an effective mechanism design that considers the SPs' profitability and the Quality-of-Service (QoS) needs of the users. We develop a generic framework to analyze and enable such interactions efficiently, leveraging tools from contract theory and mechanism design theory. It can enable and empower emerging data-sharing paradigms, such as Sensing-as-a-Service (SaaS). The contract design creates a pricing structure for on-demand sensing data for IoT users. By considering a continuum of user types, we capture a diverse range of application requirements and propose optimal pricing and allocation rules that ensure QoS provisioning and maximum profitability for the SP. Furthermore, we provide analytical solutions for fixed distributions of user types to analyze the developed approach. For comparison, we consider the benchmark case assuming complete information of the user types and obtain optimal contract solutions. Finally, a case study based on the example of a virtual reality application delivered using unmanned aerial vehicles (UAVs) is presented to demonstrate the efficacy of the proposed contract design framework.


Background:
 In patients with diffuse large B-cell lymphoma (DLBCL), adequate follow-up is required with the improvement of prognosis. The efficacy of scheduled imaging for patients with DLBCL who achieved complete response (CR) is discussed. The possibility to avoid surveillance imaging have been reported, although most studies are based on a small number of cases. The NCCN guideline version 4.2018 recommend not to perform scheduled imaging routinely for follow-up, or only for patients with stage III/IV. However, there is no strong evidence of supporting the inferiority of scheduled imaging. It is possible that some patients might benefit from scheduled imaging.
 Methods:
 We investigated patients with de novo DLBCL who were diagnosed in The Cancer Institute Hospital of Japanese Foundation for Cancer Research, Japan from 5 January 2013 to 31 May 2016 retrospectively, to conduct a sampling of first relapsed patients after CR. Patients who achieved CR after salvage therapies were included. Patients who received first-line therapy without rituximab because of non-approved use at the time were excluded. Relapse diagnosis without pathological proof were permitted. Eligible patients had a minimum of 2 years follow-up. All data were updated 17 July 2018. Overall survival (OS) was censored at the last date of follow-up.
 Relapsed patients were divided into 2 groups according to a momentum of diagnosis, clinical symptoms (symptom group) or scheduled imaging (imaging group). Clinical symptoms are defined as subjective complaint, physical exam finding and blood test abnormality. Imaging modality includes echography, computed tomography (CT), magnetic resonance imaging and positron emission tomography/CT. The Hans classifier, using CD10, BCL6, and MUM1 immunohistochemistry, was used to categorize as germinal center B-cell-like (GCB) or non-GCB.
 Fischer's test was used for comparative between the symptom group and imaging group, Kaplan-Meier test for calculate survivals, the logrank test for statistical analysis of OS, event-free survival (EFS) and survival parameters. All statistical analyses were performed with EZR software.
 Results:
 A total of 759 patients were identified as de novo DLBCL. Then 630 achieved CR, 527 had maintained CR and 103 relapsed. Among the 103 cases, 7 patients were excluded because of lack of some data. Eventually, 96 patients with first relapse were enrolled in this analysis. Relapse was confirmed pathologically in 85% (82/96) cases. Only in the symptom group, all 7 cases were not received biopsy because of central nervous system involvement. Most patients were scheduled to perform imaging every 6 months.
 We divided the 96 first relapsed patients into 2 groups by the momentum of relapse diagnosis. The median follow-up duration was 56.1 months. While 67% were detected by clinical symptoms, 33% had relapse diagnosis by scheduled imaging, and their characteristics are summarized in Table 1.
 Significant differences in the outcome were not found between the symptom group and the imaging group: 4-year OS (57%, 95% confidence interval [CI] 0.44-0.68 vs. 4-year OS: 63%, 95% CI 0.44-0.78; P = 0.517), 4-year EFS (20%, 95% CI 0.12-0.31 vs. 28%, 95% CI 0.14-0.44; P = 0.163), and median OS after first relapse (33.0 months vs. 55.4 months; P = 0.512), respectively (Fig 1).
 In the symptom group, indications were lymph node swelling (38%), neurological symptoms (20%), subcutaneous mass (17%), head and neck discomfort (10%), B symptom (6%) and blood test abnormality (3%). Univariate analysis revealed that only the existence of B symptoms at first diagnosis was significant for OS (P = 0.0361). Multivariate analysis using stepwise multiple logistic regression also demonstrated that the existence of B symptoms at first diagnosis to be the single independent factor of OS (P = 0.0402). In the imaging group, univariate analysis revealed that the existence of B symptoms at first diagnosis was significant for OS (P = 0.0241). There was no significant difference in OS between patients with stage I/II and stage III/IV in the 96 relapsed patients (P = 0.618).
 Conclusion:
 These results indicate that routine image surveillance in DLBCL patients during their first CR does not improve OS and EFS. However, B symptoms at first diagnosis was a significant factor for OS in both the symptom and imaging group, Patients with B symptoms at diagnosis might receive a benefit of image surveillance.

The aim of this chapter is to demonstrate the importance and necessity of bringing together the considerations of language and reproduction. While other topics of sexuality have aroused interest in sociolinguistics and linguistic anthropology, the ideas, practices, and experiences of human reproduction, notably pregnancy, remain understudied. At the same time, a discussion of language has been largely absent from the anthropology of reproduction, which has emerged in the last twenty years as an especially vibrant area of cultural and social study. The chapter examines the metaphors and discourses or the "talk about" reproduction; the interactions and "talk between" people, like pregnant women and medical health care providers, which shapes the ordinary experiences of reproduction; the "talk to" parties (specifically, fetuses and imagined children) who themselves become constituted through talk; and reproduction as literacy event or one that is mediated and experienced in relation to texts. It is asserted that language is a practice of reproduction.


ance of cubic symmetry line with asymmetry of the shoulders was observed with the average sizes decrease with complete disappearance of tetragonal spectrum at R • 40 nm. The comparison of the theory with experiment was carried out. The theory flts experimental data pretty good. The value of critical size Rc … 40 nm was extracted from ESR data. The asymmetry and broadening of right hand side shoulder of ESR cubic symmetry line was shown to be related to contribution of paramagnetic centers in the vicinity of the particles surface with lower than cubic symmetry. The deconvolution of the cubic line allowed to show that this region size is about 3 nm.


In this article, Lisa Yiu examines how migrant students attending public schools in Shanghai perceive teachers as uncaring and how the majority of teachers claim they are disempowered from caring. She contends that recent Shanghai reforms, which aim to "care" for migrant youth through inclusion into public schools, may be having the opposite effect, arguing that the nature of contact between educators and migrant youth is structured by conflicting state policies on citizenship, which constrain teachers from caring in the way migrant students desire. Yiu's findings problematize recent scholarship on migrant children's schooling which presumes that the dynamics of exclusion are primarily rooted in teacher prejudices. Importantly, this study advances caring theory by reconceptualizing care within the institutional context of the state's citizenship policies and contributes to a citizenship-based care praxis that is relevant to Chinese migrant youth who attend public schools.


Previous studies have shown that childhood egg allergy spontaneously resolves in the vast majority of children by school age (1, 2). However, little is documented about egg allergy recurrence, although recurrence has been recently reported for peanut (3). A 30-year old woman presented with a history of clinical reactions to egg which began at the age of 6 months, when she was given boiled egg for the first time, and immediately developed facial and truncal urticaria. As a toddler, she accidentally licked a spoon with uncooked cake mixture containing egg and again developed truncal urticaria. Thereafter she was not given egg, but developed atopic dermatitis and asthma. She was referred to a paediatrician who performed RAST tests to inhaled allergens (which were positive for house dust mite, grasses, cat, dog and moulds) but none were performed to foods. By the age of seven, the egg allergy had resolved and she could eat egg regularly. Her asthma improved after the age of 14, but her dermatitis persisted. She became pregnant at 26 years of age and ate eggs everyday for breakfast. At approximately 34 weeks gestation she began to have episodes of marked vomiting and facial urticaria, requiring hospitalization for i.v. fluids and antiemetics on four occasions until she realized the temporal relationship of the episodes to egg ingestion. After removing egg from the diet, these episodes ceased. After the birth of her child, skin prick testing revealed positive reactions to egg white (18 mm) and egg yolk (16 mm). In the following 4 years, she had three episodes of anaphylaxis, the first after eating a restaurant meal of gnocchi after being assured that it did not contain egg. After three mouthfuls, she developed abdominal cramps, vomiting, and after 10 min, severe shortness of breath. She was given two doses of adrenaline in hospital. The chef subsequently confirmed that the dish contained egg. The second episode occurred after eating a spoonful of sorbet. Within minutes she developed vomiting and shortness of breath and was again administered adrenaline in hospital. Her then 2-year old daughter had also eaten a spoonful of the same sorbet and developed abdominal cramps with generalized urticaria. This was the first time that the child had been given egg, and she was subsequently confirmed to have egg allergy, with positive skin prick tests to egg white (13 mm) and egg yolk (8 mm). On the third occasion, the mother ate a hotel room service chicken sandwich with a sauce which she had been assured did not contain egg. Within 5 min she developed abdominal cramps, vomiting and shortness of breath. She self administered adrenaline (EpiPen, CSL, Parkville, Australia) and inhaled salbutamol, but became unconscious, waking some hours later, when she was taken to a medical centre. The hotel subsequently admitted that the sauce contained egg. She continues to have chronic atopic dermatitis. This case appears to be the first report of egg allergy recurrence, demonstrating that egg allergy may have a fluctuating course. With peanut allergy, it has been postulated that once tolerance has developed, continued ingestion will assist in maintaining tolerance (3) and exposure at low, rather than high doses may paradoxically lead to greater sensitization (4). However, neither appears to have applied in this case. Food allergies may be associated with a Th2 bias in the systemic immune response (5). As the maternal immune system is biased towards a Th2 type response in pregnancy, (6) it is possible that ingesting high doses of allergen during pregnancy may have been a risk factor for allergy recurrence in this case. Patients who have grown out of egg allergy as children should be aware that symptoms may recur.


As hospitality businesses open up 'post-pandemic', the unavailability of qualified staff has become one of the biggest obstacles to businesses' ability to take maximum advantage of the pent-up desire and need for travel.
A study published by McKinsey in September 2021 under the headline "Great attrition or great attraction? The choice is yours"1 verbalised and quantified for the first time something that the hospitality industry around the globe is experiencing as businesses start their return to the 'next normal'. The article explained in detail a mindset that has become commonplace both for employers and employees, and that will be troubling the industry for a while if not properly addressed.
When Covid first brought the world to a standstill, the hospitality industry was one of the first and worst hit. Business came to a halt; many hotels and restaurants closed or decreased staffing levels as much as possible in order to cut expenses. In the developed world, this was done with the help of government programmes so that employees could access some kind of safety net. In developing countries, these safety nets often did not/do not exist. Many employers were ruthless, simply telling staff that they were no longer needed. 'Thanks' to many governments calling Covid-19 a "force majeure", employers got around paying legally required compensation for terminating employees at short notice. Many of our colleagues, expatriate and local, found themselves literally 'on the street' within weeks of the pandemic ravaging the industry.
Employers' social responsibility to the communities in which they do business was one of the first victims of the pandemic. The understanding that "our staff is our most valuable asset" turned into pure semantics.
Today, as these businesses celebrate that they are opening again, there is a surprising level of surprise among the most callous of employers that now they can't find staff. The industry will have to come up with new ways of working if they want to attract colleagues back – the loss of trust and goodwill will have serious repercussions. To 'make good' on their actions, employers need to first understand how much they broke – initial observations show that they have not even started to understand what they did.
What about people still employed? Shouldn't they be lucky to still have a job? In the McKinsey study, 40% of participants who were still employed answered that they were at least somewhat likely to leave their job in the next 3–6 months; 64% of these claimed that they are planning to leave without a new job lined up.
At the core of this is, I believe (and the study suggests), is a general disconnect between what employees are looking for and what employers think that employees are looking for. The pandemic has sent many of us into a survival mode, forcing actions that were purely transactional. Yet the hospitality industry, at its core, depends on people who care for others. Employers need to ask employees questions that show they care and rebuild the trust that has been lost due to their actions when the pandemic hit.
As a member of a Vietnamese investment group that did exactly the opposite, that held on to employees at substantial cost to the enterprise and with employees at all levels 'chipping in' through unpaid leave to help keep everyone employed, I know first-hand that this has built a substantial amount of trust and our levels of attrition are substantially below the market average as other businesses reopen. Asking the right questions, listening to the answers and consistently responding with empathy and tangible action, not words, will be key to our success.

Remote sensing of aerosol optical depth (AOD) could be used to assess particulate matter levels at the ground; however, such measurements often need further validation. AOD is a measure of aerosol loading in the atmosphere, which means a higher AOD shows a higher aerosol loading and thus lower visibility. Aerosol concentration, determined by AOD, affects air quality in urban and semi-urban environments.


This paper reports the wear characteristics of two types of coating materials, which are Cr₂O₃ and ZrO₂, by coated plasma thermal spray method. The wear test was carried out under air, grease, and bearing fluid conditions. The wear testing machine of a pin-on disk type were used to measure friction forces, friction coefficients and the weight losses of the coating specimens on the various sliding velocity and loading condition. The wear surface of specimens were observed by scanning electron microscope (SEM) photographs.

In this paper, a class of linear infinite‐dimensional systems with discrete and distributed time‐varying delays is studied. New sufficient conditions for the robust H∞ control of linear time‐varying control systems with mixed time‐varying delays in Hilbert spaces have been established. The conditions are given in terms of the solution of a Riccati differential equation. Furthermore, it is proved for the first time that the solution to the robust H∞ control problem can be solved by the global controllability of an appropriate linear control delay‐like system.

From 82 college Ss were obtained three measures developed from a theory of discrimination systems: number of discriminable categories along scales of discrimination applied to persons, number of different bi-polar scales used to discriminate between persons, and a rating of the level of abstraction of descriptions of a single Other person. Three attitude measures, acceptance vs rejection of change as a general, over-riding attitude, reliance upon self vs reliance upon others, and extreme sexual restraint vs affirmation of sexuality, were obtained, and all Ss predicted the choices of a female Other in 40 concrete situations before receiving her actual choice. The hypothesis that all seven of these measures would intercorrelate was not confirmed since the measures formed two clusters.


Abstract The recent progress in our understanding of the dynamics of muliti-phase interstellar medium (ISM) is reviewed. Non-linear perturbations (e.g., shock waves or time-dependent radiation field) lead to the interchange between warm phase and cold phase via thermal instability. Dynamical modelling of this phase transition dynamics is essential in describing ubiquitous turbulence in ISM and the formation of molecular clouds. A concept of magnetically multi-phase medium is introduced. Recent finding of the magnetic field amplification in the blast wave propagating in magnetized multi-phase ISM is providing a strong motivation for rapid acceleration of cosmic rays.


Clinical practice guidelines are consensus statements developed by various bodies about what constitutes appropriate treatment for a specific condition or preventive care goal. Because they derive from the consensus of experts, practice guidelines are thought to represent the prevailing standard of care in the medical profession. In the last decade, would-be tort reformers have suggested using practice guidelines as evidence of the legal standard of care in medical malpractice litigation. They have argued that this would reduce the uncertainty that health care providers presently face regarding what the standard of care is, and consequently would ease the pressures that lead providers to practice "defensive medicine." This article argues that while there may be certain efficiencies associated with the use of practice guidelines as the legal standard of care, their use is deeply problematic. Among the reasons to disallow their use as inculpatory evidence (by plaintiffs) is that practice guidelines do not, in fact, appear to represent prevailing medical practice in most instances. Some states have, by statute, restricted the use of practice guidelines in litigation to use as exculpatory evidence by defendants. However, this one-way use of relevant, probative, and otherwise admissible evidence is an anomaly in the law that lacks sufficient justification. The best course of action is to restrict the use of practice guidelines by both defendants and plaintiffs in medical malpractice litigation.


Intracerebral levels of Transforming Growth Factor beta (TGFβ) rise rapidly during the onset of experimental autoimmune encephalomyelitis (EAE), a mouse model of Multiple Sclerosis (MS). We addressed the role of TGFβ responsiveness in EAE by targeting the TGFβ receptor in myeloid cells, determining that Tgfbr2 was specifically targeted in monocyte‐derived dendritic cells (moDCs) but not in CNS resident microglia by using bone‐marrow chimeric mice. TGFβ responsiveness in moDCs was necessary for the remission phase since LysMCreTgfbr2fl/fl mice developed a chronic form of EAE characterized by severe demyelination and extensive infiltration of activated moDCs in the CNS. Tgfbr2 deficiency resulted in increased moDC IL‐12 secretion that skewed T cells to produce IFN‐γ, which in turn enhanced the production of moDC‐derived reactive oxygen species that promote oxidative damage and demyelination. We identified SNPs in the human NOX2 (CYBB) gene that associated with the severity of MS, and significantly increased CYBB expression was recorded in PBMCs from both MS patients and from MS severity risk allele rs72619425‐A carrying individuals. We thus identify a novel myeloid cell‐T cell activation loop active in the CNS during chronic disease that could be therapeutically targeted. GLIA 2016;64:1925–1937


We demonstrate resonance Raman spectroscopy in microfluidic channels for the analysis of whole blood. In particular, cell-free plasma layers are created in microfluidic whole blood flow by means of temporary hydrodynamic cell filter functionality. In-line confocal Raman spectroscopy is applied at the location of the created cell-free plasma layer and we detect free hemoglobin at diagnostic relevant hemolysis concentrations.

Raman spectroscopy is a semi-quantitative method for chemical analysis. Due to the uniqueness of molecular vibrations, its selectivity is dependable. However, Raman scattering intensity is often too weak to be detected. This weakness can be overcome by resonance Raman spectroscopy where the laser excitation frequency is chosen corresponding to a dipole-allowed electronic transition of the molecule under study [1]. By employing resonance Raman spectroscopy we investigate bovine blood samples inside microfluidic channels in a micro-Raman setup, putting analytical emphasis on hemoglobin. Resonance Raman spectroscopy of hemoglobin was first demonstrated in 1972 [2] where aqueous solutions with concentrations of approximately 10-4 M were examined. Here we detect hemoglobin dissolved in bovine blood plasma inside 40μm deep PDMS channels. Most dominantly in our Raman spectra, the characteristic oscillatory mode of the central porphyrin ring structure of hemoglobin at 1375cm-1 appears. Despite the background in the Raman spectrum due to fluorescent emission from plasma proteins we are able to detect hemoglobin at concentrations from as low as 10-5 M and higher. The range of clinical relevance for hemolysis can be accurately resolved.

The chemical analysis of liquid suspensions is of major interest to e.g. food industry, biotechnology and chemical industry. In this respect, it is desired to separate the suspending liquid from diluted particles, cells or beads [3]. A temporary particle or cell separation as proposed here is sufficient in order to analyze the suspending liquid in transit by micro-Raman spectroscopy. The microfluidic PDMS channels used in our whole blood experiments are 30-60μm wide and 40μm deep. In general, blood cells in flowing blood tend to migrate to the center of a microfluidic channel (Fahraeus–Lindqvist effect [4]), leaving a cell-free plasma region of 1-3μm at the channel walls. This cell-free plasma region can be locally expanded by the sudden enlargement of the microfluidic channel. In this way we create expanded semi-stagnant cell-free blood plasma regions of 5-20μm in width in close vicinity to whole blood flow. These regions are large enough to enable the application of localized confocal Raman spectroscopy exclusively in cell-free blood plasma. Hemolysis levels of whole bovine blood have been determined in this way.

Background: The incidence of sepsis is worldwide. We aimed to assess the value of enhanced red cell distribution width (RDW) to predict sepsis and evaluate factors affecting length of intensive care units (ICU) stay and inhospital mortality among sepsis patients. Materials and Methods: In a prospective study, we had 187 patients, which after exclusion of 27 patients, we included 160 adult patients with suspicious sepsis admitted in the university affiliated Hospital with 33 ICU-beds from 2010 to 2012. Nighty patients were diagnosed with sepsis and the source of infection was defined. Receiver–operating characteristic (ROC) curves were used to examine the sepsis predictions from RDW, APACHE II scores, and combination of them. The primary endpoint of this analysis was ICU mortality. The secondary endpoints were length of stay in ICU and hospital. A linear regression analysis was used to study risk factors for longer ICU stay and we used Logistic regression analysis to predict factors affecting inhospital mortality. Results: The addition of elevated RDW value to acute physiology and chronic health evaluation (APACHE) II score in critically illness states enhanced the AUC for predicting sepsis and its differentiation from SIRS. Female patients and those with numerous co-morbidities or AKI and those on mechanical ventilation significantly stayed longer in ICU. Moreover, the patients with higher APACHE II score died significantly more than others . Conclusion: The addition of elevated RDW value to APACHEII score in critically illness helps to differentiate sepsis from SIRS.


A structural determination of the high-temperature form γ-Sn2F6 has been performed using neutron diffraction. This mixed fluoride exhibits the cubic ordered ReO3-type structure (Fm3m space group) with a = 8.321(4) A at 497 K. The bond lengths SnIIF and SnIVF give evidence of the presence of tin(II) in the (a) site and tin(IV) in the (b) site. A cationic ordering has also been found in the intermediate form β-Sn2F6 whose structure is related to the LiSbF6-type.


A long time coherent accumulation method based on sub-pulse matching correction (SPMC) is proposed in this paper to solve the problems of radar moving target echo across range units and across Doppler. This method adopts the reverse search process from the echo signal to the target velocity, setting the sub-pulse matching factor to accomplish exponential sub-pulse search process. Under the premise of robust performance of parameter measurement and target detection, the calculation amount is greatly reduced compared with the original method. Then, through formula derivation and simulation calculation, the similarities and differences between the proposed method and Radon-Fourier transform (RFT) are analyzed and compared from the aspects of operation steps, blind velocity response and operation amount. Finally, several groups of simulation experiments are carried out to prove the universality and robustness of the proposed method.


1From an outsider's perspective, this witticism might appear to hold some truth. After all, the two cities' downtowns are a relatively "short" 100-minute commute from one another. New Yorkers flocked to Phil adelphia in the early-to-mid 2000s to take advantage of a downtown condo boom. And anyone who has ever visited Philadelphia knows that its older neighborhoods—


ABSTRACT Time-resolved X-ray powder diffraction may be used to elucidate the structure of polycrystalline matter, but a fast-response full-profile detector is often necessary. This article describes a Mythen detector incorporated in beamline 4B9A of the Beijing Synchrotron Radiation Facility. Basic parameters of this detector are reported, and flat-field correction, angular calibration, eccentric error, and other data treatment for this detector are discussed. X-ray diffraction measurement of lanthanum boride demonstrates that this detector provides high-quality, time-resolved X-ray powder diffraction measurements.


The arising of SARS-CoV-2 or 2019 novel coron-avirus in December 2019 have prioritized research on pulmonary diseases diagnosis and prognosis, especially using artificial intelligence (AI) and Deep Learning (DL). Polymerase Chain Reaction (PCR) is the most widely used technique to detect SARS-CoV-2, with a 0.12% false negative rate. While 75% of the hospitalized cases develop pneumonia caused by the virus, patients can still develop bacterial pneumonia. COVID-19 pneumonia can be diagnosed based on clinical data and Computed Tomography (CT scan). However, Chest X-rays are faster, cheaper, emit less radiations, and can be performed on bed-side. In this article, we extend the application of VGG-16 based Faster Region-Based Convolutional Neural Network (Faster R-CNN) to the detection of Pneumonia and COVID-19 in Chest X-ray images using several public datasets of total images count ranging from 2122 to 18455 Chest X-rays, and study the impact of several hyper-parameters such as objectness threshold and epochs count and length, to optimize the model's performance. Our results comply with the state of the art of Faster R-CNN in pneumonia detection as the best accuracy achieved is 65%. For COVID-19 detection, Faster R-CNN achieves a 90% validation accuracy.


C72H52Co4N12O28S4, monoclinic, P2/c (no. 13), a = 14.120(2) Å, b = 8.4612(9) Å, c = 20.550(2) Å, . = 129.470(5)°, V = 1895.3 Å, Z = 1, Rgt(F) = 0.028, wRref(F ) = 0.077, T = 291 K. Source of material A mixture of 5-nitroisophthalic acid (O2N-H2ip, 0.1 mmol, 20.5 mg), 4,4'-bipyridyl sulfide (bps, 0.1 mmol, 18.9 mg), Co(OAc)2 · 4H2O (24.7 mg, 0.1 mmol), KOH (0.1 mmol, 5.5 mg) and H2O 18 ml was placed in a Teflon-lined stainless steel vessel, heated to 180 °C for 3 days, and then cooled to room temperature over 48 h. Red block-shaped crystals of the title compound were obtained. Discussion The design of metal-organic coordination polymers is of current interest in the fields of supramolecular chemistry and crystal engineering. Major reasons for this interest stem from the intriguing variety of topologies and structural diversity, such as helixes and diamondoid nets, and because of their potential applications as functional materials, such as hetero-geneous catalysis, molecular recognition, magnetism, gas storage, ion exchange, nonlinear optics, and electrical conductivity [1,2]. It is well known that organic ligands play crucial roles in the design and construction of desirable frameworks. In this context, benzenedicarboxylic acid and their derivatives (such as 1,3-benzenedicarboxylic acid, 1,4benzenedicarboxylic acid, 5-nitroisophthalic acid, 5-hydroxyisophtalic acid etc.) are widely used as building blocks to link metal ions to produce interesting metal-organic framework structures and properties [3,4]. On the other hand, in contrast to the large and increasing amount of work on the synthesis with ligands containing O or N donors, there have been fewer reports of studies based on organothiolate ligands. 4,4'-Dipyridyl sulfide (dps) possesses a non-linear backbone due to the bend around the sulfur atom, and may yield various coordination polymers [5]. The fundamental building unit of the title crystal structure contains two cobalt ions, two O2N-ip ligands, two bps ligands and two coordinated water molecules (figure, top). The Co1 ion is 6coordinated with a distorted octahedral environment. The six atoms coordinated to each Co(II) ion come from two carboxylate oxygen atoms from two O2N-ip ligands, two water molecules and two nitrogen atoms from two bps ligands. Co2 adopts a distorted tetrahedral [N2O2] coordination, and is coordinated by two carboxylic oxygen atoms from two O2N-ip ligands and two bps nitrogen atoms. The Co—O and Co—N bond lengths are in the range of 1.978(2) 2.173(2) Å and 2.059(2) 2.178(2) Å, respectively. Every bps ligand adopts a bis-monodentate bridging mode and links neighboring Co(II) ions, resulting in a 1D chain. The 1D chains are further connected by O2N-ip ligands to give a puckered 2D sheet (figure, bottom). It is noteworthy that O2N-ip serves as not only coordinative ligands, but also weak-interaction donor and acceptor. It is interesting to observe that the adjacent 2D layers are connected by O···O intermolecular contacts (d(O4···O5) = 3.019 Å) between the uncoordinated carboxylate oxygens and the -NO2 groups of O2N-ip ligands, leading to a 3D supramolecular network.

Effect of external electric field on the properties of Rayleigh wave propagation in YZ-LiNbO3 is analyzed theoretically. Second-order material constants are altered by the biasing electric field and third-order material constants can't be neglected. It is found that the fractional change of phase velocity caused by electric field in present contribution coincide with the previous experimental results perfectly. Conclusions in this paper are very useful for improving the performance of surface acoustic wave devices.


Background Anterior circulation infarction (ACI) accounts for almost 70% of all strokes, whereas posterior circulation infarction (PCI) accounts for 20% of the strokes, with heterogeneous clinical manifestations. Objectives The aim of the present study was to compare the clinical characteristics of ACI with PCI, and to detect the diagnostic importance of specific symptoms and signs for PCI. Patients and methods We prospectively analyzed acute ischemic cerebral stroke (AICS) patients, enrolled in the study from the convalescence and critical cases of Mansoura University Hospitals (CCCB-MUH) during a 1-year period. Patients were analyzed for ischemic stroke subtypes (ACI and PCI), demographic data, risk factors, and clinical characteristics. All patients underwent an assessment by using the Glasgow Coma Scale and the National Institutes of Health Stroke Scale at the onset of AICS. Results The study included 234 patients with AICS (174 belonging to the ACI subtype; 60 to the PCI subtype). PCI patients were often men, had a higher presence of cervical spondylosis, lower mean National Institutes of Health Stroke Scale, and a lower mean Glasgow Coma Scale. PCI patients had a greater frequency of diabetes and smoking. Among the PCI patients, ataxia, vertigo, unsteadiness, nystagmus, crossed motor, and sensory deficits were statistically significant compared with the ACI patients. As regards speech disturbances, aphasia occurred in a low percentage of the PCI patients, and no statistically significant difference regarding dysarthria was found in the two groups. The neurological deficits favoring the diagnosis of PCI were nystagmus, crossed motor and sensory deficits, ataxia, vertigo, unsteadiness, diplopia, Horner's syndrome, and oculomotor nerve palsy. Conclusion There is an apparent difference in the frequency of the most common manifestations between PCI and ACI patients. Some neurological deficits were highly specific for diagnosing PCI.

HF radars typically produce maps of surface current velocities without estimates of the measurement uncertainties. Many users of HF radar data, including spill response and search and rescue operations, incorporate these observations into models and would thus benefit from quantified uncertainties. Using both simulations and coincident observations from the baseline between two operational SeaSonde HF radars, we demonstrate the utility of expressions for estimating the uncertainty in the direction obtained with the Multiple Signal Classification (MUSIC) algorithm. Simulations of radar backscatter using surface currents from the Regional Ocean Modeling System show a close correspondence between direction of arrival (DOA) errors and estimated uncertainties, with mean values of 15° at 10 dB, falling to less than 3° at 30 dB. Observations from two operational SeaSondes have average DOA uncertainties of 2.7° and 3.8°, with a fraction of the observations (10.5% and 7.1%, respectively) having uncertainties of >10°. Using DOA uncertainties for data quality control improves time series comparison statistics between the two radars, with r2=0.6 increasing to r2=0.75 and RMS difference decreasing from 15 to 12 cm s−1. The analysis illustrates the major sources of error in oceanographic HF radars and suggests that the DOA uncertainties are suitable for assimilation into numerical models.

We present an investigation of Er 3+ photoluminescence in Y 2 O 3 waveguides codoped with Eu 3+ . As a function of europium concentration we observe an increase in decay rate of the erbium 4 I 11/2 energy level and an increase of the ratio of photoluminescence emission from the 4 I 13/2 and 4 I 11/2 states. Using a rate equation model, we show that this is due to an energy transfer from the 4 I 11/2 → 4 I 13/2 transition in erbium to europium. This increases the branching ratio of the 4 I 11/2 state towards the 4 I 13/2 state and results in a higher steady state population of the first excited state of erbium. Absolute intensity enhancement of the 4 I 13/2 emission is obtained for europium concentrations between 0.1 and 0.3 at. %. In addition, the photoluminescence due to upconversion processes originating from the 4 I 11/2 state is reduced. Using such state-selective energy transfer the efficiency of erbiumdoped waveguide amplifiers can be increased.
