The physical stochastic optimal control strategy is extended,and a novel nonlinear optimal control method for randomly excited hysteretic systems is developed,referring to the optimal polynomial control scheme.For an illustrative purpose,the nonlinear stochastic optimal control of an earthquake-excited multi-degree-of-freedom hysteretic structure described by Bouc-Wen differential model is carried out.Numerical results reveal that the linear control with the 1st-order controller suffices even for the hysteretic systems when an exceedance probability based control criterion for designing the optimal weighting matrices is employed.This is practically meaningful since it bypasses the need to utilize nonlinear controllers which may be associated with dynamical instabilities due to time delay and computational dynamics.It is remarkable,meanwhile,that the structural response,hysteretic behavior and energy dissipation of the controlled system can be improved to a desirable performance,which elucidates the validity and applicability of the developed nonlinear stochastic optimal control methodology.


Synthesis of metal nanoparticles with a narrow size distribution is a laborious process, requiring conditions control so its commercial application is limited. The use of a simple one-step synthesis with subsequent modification of nanoparticles is a promising approach. In this paper a method for changing the mean diameter of gold nanoparticles synthesized using gum arabic as stabilizing agent was described. The average diameter of gold nanoparticles may be increased by a shell of silver on the surface, whereas the diameter decrease is provided by boiling the solution after nanoparticles synthesis. Presented approach eliminates the low accuracy of the gold nanoparticles synthesis method by using gum arabic as a stabilizing agent.

Innovative welding processes are continuously gaining industrial interest. Both hybrid laser welding (HLW) and friction stir welding (FSW) are automated welding processes which allow achieving high quality joints in aluminum alloys, in combination with a high productivity. It is important to assess the capability of the processes, not only in terms of weld quality but also in terms of productivity and profitability. The EN AW-6056 alloy is a recent high strength weldable AlMgSiCu alloy, which is utilised in aviation. This alloy, with a thickness of 2,5 mm, was subjected to HLW and FSW. The optimisation procedure which was used for HLW to assess the most appropriate welding parameters will be discussed in detail. A comparison is made between the mechanical properties in the as-welded and in the T78 post-weld heat treatment (PWHT) temper. Fatigue testing of unnotched welded specimens with a ratio of maximum stress to minimum stress equal to 0,1 was applied to this alloy in the PWHT condition. Results obtained with both welding techniques are compared and discussed in this paper.Innovative welding processes are continuously gaining industrial interest.

Instantaneous, dynamic and time-averaged characteristics of the vortex structures which are shed from the dimples placed on one wall of a channel are described. The dimpled test surface contains 13 staggered rows of dimples in the streamwise direction, where each dimple has a print diameter of 5.08 cm, and a ratio of depth to print diameter of 0.2. Considered are Reynolds numbers (based on channel height) ReH from 600 to 11 000, and ratios of channel height to dimple print diameter H/D of 0.25, 0.50, and 1.00. For all three H/D, a primary vortex pair is periodically shed from the central portion of each dimple, including a large upwash region. This shedding occurs periodically and continuously, and is followed by inflow advection into the dimple cavity. The frequency of these events appears to scale on time-averaged bulk velocity and dimple print diameter, which gives nondimensional frequencies of 2.2–3.0 for all three H/D values considered. As H/D decreases, (i) the strength of the primary vortex pair in...


Background: Ponatinib is an approved potent, oral, pan-BCR-ABL inhibitor active against native and mutant BCR-ABL. Ponatinib had substantial clinical activity in the phase 2 PACE trial in patients (pts) resistant or intolerant to dasatinib or nilotinib or with the T315I mutation. In the frontline setting, positive associations between achieving response at an early time point (landmark) and long-term outcomes have been shown for tyrosine kinase inhibitors (TKIs) in CML pts. Since landmark analyses have not been reported for a heavily pretreated population, in particular 3rd line and beyond, this retrospective analysis investigated the impact of achieving early landmark responses with ponatinib on long-term outcomes in PACE pts. Methods: Ponatinib treated CP-CML pts in PACE with valid cytogenetic and molecular assessments were included. Pts who met response criteria at entry, were missing assessments or not evaluable ( 10%) and cytogenetic status (MCyR, Results: 267 CP-CML pts were included in the analysis: 54% male; median age, 60 (18-94) years; median time from diagnosis, 7 (0.5-27) years. Pts were heavily pretreated: 60% received ≥3 TKIs. At 3 months, 51%, 36%, and 15% pts had reached ≤10% BCR-ABLIS, ≤1% BCR-ABLIS, and MMR, respectively. Pts who achieved each of these responses at 3 months were significantly more likely to have improved PFS after 2 years compared with those who did not (Table). The trend was similar for OS: specifically, pts who reached ≤1% BCR-ABLIS or MMR at 3 months had a significantly increased likelihood of OS after 2 years. Moreover, 3-month BCR-ABLIS levels correlated with achievement of deeper molecular response (MR4 and MR4.5) over time: pts with low BCR-ABLIS levels (≤1%) were more likely to achieve MR4 or MR4.5 compared with those having higher BCR-ABLIS levels (>10%). Furthermore, pts who achieved MCyR or CCyR at 3 months were significantly more likely to have improved PFS after 2 years compared with those who did not. This trend was similar for OS: achievement of MCyR or CCyR at 3 months was associated with an increased likelihood of OS after 2 years (Table). Similar trends were observed for 6-month molecular and cytogenetic landmark analyses (Table). Conclusions: In these refractory CML pts, the rapid and deep reduction in BCR-ABL levels achieved with ponatinib translated into improved long-term outcomes. These data validate the usefulness of assessing BCR-ABL levels at early time points as a goal of therapy with ponatinib since achieving early landmark response appears to be a strong predictor of better long-term outcomes.

Thin films of red color poly(2-methoxy-5(2′-ethylhexyloxy)-phenylene vinylene) (MEH-PPV) containing different weight percent of ZnO nanoparticles were obtained by spin-coating techniques. The MEH-PPV:ZnO solutions were spin coated onto silicon and glass substrates. The spun MEH-PPV:ZnO thin films were then used to investigate optical properties by using ultravioletvisible spectrometer (UV-Vis) and photoluminescence spectrophotometer (PL). The morphologies were investigated by using field emission scanning electron microscopy (FESEM), while the identification of ZnO in the final product was determined by using energy-dispersive X-ray spectroscopy (EDS). The UV-Vis absorption band increases, while the optical bandgap decreases when the amount of ZnO nanoparticles increases. ZnO nanoparticles apparently have no effect on the conjugation segments of MEH-PPV. PL spectra show that the emission peak increases and slightly red shift as ZnO concentration increases. Based on SEM images of MEH-PPV:ZnO nanocomposite thin films, ZnO nanoparticles form agglomerated regions.


Abstract : The report covers a study performed to assess the predictability of 5-, 10-, 15-, 30-, and 60-minute average wind directions. This was compared to 1-minute values obtained in a previous study. A limited study was also made to assess the spatial variability of wind fields. Again, this was compared to point locations previously studied. (Author)


Based on LAPS data assimilation systems analysis fields and microwave radiometer data,etc.,a local strong hail event taking place in Li County,Changde City of Hunan Province in June 3,2008 was analyzed in terms of the thermal and dynamic condition.The environmental conditions and mechanism leading to the hail was analysed as well.The results show that assimilation of radar data LAPS analysis fields can reveal the accurate dynamic structure of hail events,while it has no significant improvement in describing the thermal parameters.Strong storms were in a humid environment with strong vertical wind shear,potential instability and abundant water vapor.The moisture convergence located at 1000-925 hPa,and there was a slope and stronger moisture convergence region in the south of severe storms.The main system arousing super monomer(hail) is small and medium-scale cyclones located in the lower-middle troposphere.High-level was anticyclone divergence zone.Middle-level was mainly dry and cold northwest air.The various physical fields of LAPS output can be used to diagnose the development of strong convection,and especially have a stronger interpretation and application capability to the structure of such small-scale weather systems leading to hail.


Raspberry cultivars ( Rubus spp.) were screened for their susceptibility to larvae of the New Zealand raspberry bud moth, Heterocrossa rubophaga Dugdale (= Carpostna adreptella Walker). A useful degree of resistance was found in some black and purple raspberry cultivars being selected for other agronomic characteristics. This useful trait was inherited in offspring of crossesmade with resistant parents. Results of resistance evaluation in an excised leaf test and an excised shoot test were similar. Resistance in raspberry cultivars to H. rubophaga and a leaf roller Eptphyas postvtttana (Walker) did not appear to be related. Development from egg hatch to adult emergence of the bud moth larvae on blackberry, R. echtnatus Lindley, averaged 35.5 d. When given a choice, adult moths laid about three times more eggs on blackberry than red raspberry shoots. Eggs were stored for up to 10 d at 4°C without any adverse effect on egg hatch and larval establishment.


The occurrence of microorganisms and their relationships with total and available heavy metal concentrations (Cu, Zn, Pb, Cr, Ni, Cd, Hg, and As), as well as main soil chemical characteristics (pH, P, K, Ca, Ntot, Corg) were evaluated in naturally metalliferous serpentine soils and non-serpentine soils with elevated Ni and Cr concentrations. Significant negative correlations were detected between ammonifiers (r = -0.545, r = -0.371), oligonitrofiles (r = -0.478, r = -0.458), total number of microorganisms (r = -0.363, r = -0.393), and available Ni and Cr. The number of actynomicetes and Azotobacter spp. was not affected by heavy metal concentrations, nor any other soil chemical characteristic. Ammonifiers correlated positively with P and K soil content, but negatively with soil Corg. High positive correlations were obtained for available metal concentrations and soil Corg and Ntot, while soil pH only correlated with available Cr and As. Stepwise multiple regression analyses indicated that increased Ni and Cr concentrations had overall little influence on microbial groups, and only ammonifiers were significantly affected by increased available Ni, but P content had an even higher effect on their number in soil.


In the presented paper, model of the Internet-of-Things node for Home Area Network (HAN) in Smart Grid (SG) is proposed. The node is supposed to be a universal part of the customer's local infrastructure. It can connect different sensors that can be substituted further according to the customer's demands. This capability is ensured by the proposed configuration description scheme that locates within the node. In comparison with known solutions, the proposed approach does not require reprogramming device in case of its function has been changed. Many nodes can connect to the network simultaneously, providing scalable solution for information and control systems in HAN within SG. The developed node prototype implements statement proposed in this work. The proposed model brings to the system advantages of such non-functional features as flexibility, ease of configuration changes without reprogramming node device. Test node implemented according to the claimed theoretical statements can work with different sensors without programming node components.


The mechanical properties of Indium Phosphide (InP) nanowire is an emerging issue due to its application as optoelectronic material. In this paper, atomistic simulations are conducted to find thermo-mechanical properties of Indium Phosphide (InP) nanowire under uniaxial tension. Vashishta potential is employed to define the atomic interactions between the atoms. The effect of variation of temperatures (100K-500K) on the tensile response of the InP nanowires is investigated in this study. Also, size effect is investigated for the temperature of 300 K by varying the cross sectional area of the nanowire. Results suggest that increment of temperature results in the failure of InP nanowire at a lower value of stress (from 8.60 GPa at 100K to 6.50 GPa at 500K) along with the decrement of Young's modulus. Results also suggest that size has little effect on the tensile properties of this nanowire. Finally, failure mechanisms of indium phosphide nanowire are also investigated from the atomic images obtained from the simulation results.The mechanical properties of Indium Phosphide (InP) nanowire is an emerging issue due to its application as optoelectronic material.

The role of emotional and social signals in multimedia has not been a core concern of the multimedia research community--an omission explored at the 22nd ACM International Conference on Multimedia during a panel titled, "Emotional and Social Signals in Multimedia: Where Art Thou?" The panel discussion revealed major gaps in the formulation, understanding, and application of emotional and social signal processing in the multimedia domain. Here, the authors review the challenges in bringing this new domain to multimedia, summarizing current feelings in the research community based on discussions during the panel.


We present a light field imaging system that captures multiple views of an object with a single shot. The system is designed to maximize the total light collection by accepting a larger solid angle of light than a conventional lens with equivalent depth of field. This is achieved by populating a plane of virtual objects using mirrors and fully utilizing the available field of view and depth of field. Simulation results demonstrate that this design is capable of single-shot tomography of objects of size 𝒪(1 mm3), reconstructing the 3-dimensional (3D) distribution and features not accessible from any single view angle in isolation. In particular, for atom clouds used in atom interferometry experiments, the system can reconstruct 3D fringe patterns with size 𝒪(100 μm). We also demonstrate this system with a 3D-printed prototype. The prototype is used to take images of 𝒪(1 mm3) sized objects, and 3D reconstruction algorithms running on a single-shot image successfully reconstruct 𝒪(100 μm) internal features. The prototype also shows that the system can be built with 3D printing technology and hence can be deployed quickly and cost-effectively in experiments with needs for enhanced light collection or 3D reconstruction. Imaging of cold atom clouds in atom interferometry is a key application of this new type of imaging device where enhanced light collection, high depth of field, and 3D tomographic reconstruction can provide new handles to characterize the atom clouds.

This study examines selected Igbo written poems so as to observe the extent to which the poets have represented various natural phenomena such as trees, sun, moon, rain, among others and the relationship between man and his environment in their poems. It is obvious that some Igbo poets like the Western poets represent some natural phenomena in their creative works. Their major concern is to project these natural phenomena and enhance the relationship between humans and these phenomena through their literary works. In spite of the efforts of many Igbo poets in representing different natural phenomena in their poems, previous studies have shown that some Igbo literary scholars, critics, teachers and students show more interest in studying other issues represented in Igbo written poetry like issues that border on the society, politics, leadership, gender, religion, culture, economy, among others. This shows that they do not have interest in the natural phenomena and the purpose for their representation in written Igbo poetry. It is against this backdrop that this study examines the natural phenomena prominent in the selected Igbo written poems so as to identify the nature of relationship between these natural phenomena and man as projected by the poets. The study adopted the ecocritical literary theory in analysing the selected poems and the data were presented descriptively. From the analysis, this study reveal that the selected poems represented the importance of some natural phenomena to man especially the economic values. This study also observed that there is good relationship between the natural phenomena projected in the selected poems, among other findings. It is hoped that this study would help to project and enhance the relationship between man his environment.

It was established early on in this study that a Language, Literacy and Culture Program (LLC) site is needed to keep the community connected. A community-centered design was considered, and implemented in the fall of 1999. The current study was implemented to assess why the site failed and what could be done to revive it. The findings of the current study indicated that the community did not develop as expected despite the team's effort to follow a community-centered approach. In this paper we consider the reasons for the site's failure, and what could be done to revitalize the community. Through surveys, and interviews it was determined that the community needed more active participation from the moderator and faculty. They also required a more interactive and better developed design, and special care should be taken to train the members who need it on the use of technology involved.


shown to be very effective in the treatment of parenchymal cysts.' The role of praziquantel in the treatment of intraventricular cysts has not been established; however, in view of case reports describing unsuccessful outcomes with praziquantel, surgery remains the treatment of choice." Praziquantel was used in this case in view of spillage of the cyst contents at the time of surgery and as the patient had emigrated only recently he may have had early cysts which could cause problems after a latent period of up to 25 years.


In this thesis we deal with numerical methods used for solving non-linear time dependent partial differential equations, where the biggest challenge is numerical approximation of the gradient. We apply this approach in two fields, therefore is the thesis divided into two parts. In the first one we present finite volume scheme based on the EHM (Eymard-Handlovicova-Mikula) approach and apply it in the image segmentation process. We introduce new model, so-called regularised Riemannian mean curvature flow equation. For this new model we prove the necessary theoretical aspects as uniqueness of the numerical solution, stability estimates for the numerical solution and the convergence of the numerical scheme to the solution. Regularised Riemannian mean curvature flow equation is tested on the benchmark examples to prove its suitability. In the end of the section two different approaches of the approximation of the non-linear smoothing term are discussed and compared. The second part of the thesis is dedicated to the introduction of the discrete duality finite volume (DDFV) method and the application of this method for modelling of the development of the financial derivatives' price in time. So-called Heston model and its regularized version are studied. For the regularised model the stability estimates on the numerical solution and the convergence of the numerical scheme to the solution are proven. The last part is dedicated to the numerical experiments for the DDFV method for the regularised Heston model.


Counties are responsible for local public transport in Norway. The prevalent form of organisation is that private companies operate on net-cost contracts for the counties. The county authorities determine both the fares and the level of service. Competitive tendering is permitted and the threat of tendering has contributed to increased X-efficiency in the bus industry. The main problem at present is the lack of incentives for market, or allocative efficiency. A new type of contract has recently been introduced in Norway. It allows operators greater freedom in the design of services, and a remuneration scheme is linked to the level of service provided. It is intended that this remuneration to operators will internalise the social benefits from an improved level of service since only a small fraction of these benefits is captured by increased fare revenue. By proper design of the remuneration scheme, the level of service provided by private operators who maximise profit will approximate the social optimum. © The London School of Economics and the University of Bath 2001


In order to study excavation effects to engineering characteristics of the granite residual soil(GRS),some tests on compressibility and shear strength were carried out to study the effects of dried shrink age,stress unloading, saturation softening and reinforcement of cement grout due to excavation,then the landslide mechanism of its cutting slope was researched from the angles of geometric microstructure and damage.The main results as follow: As the unrestrained surface is formed and exposed after slopes are excavated,dried shrink age,stress unloading,saturation softening will cause GRS softening,moreover,when they coexist,their softening effects will be intensified;When GRS is treated by cement grout,its disturbed microstructure will be restored and reinforced to a certain extent,and the softening effects will be weaken;The advanced microstructure geometric model of GRS accords with its micro-features essentially,based on the model,the above-mentioned effects can be explained properly and the landslide micro-mechanism of GRS cutting slopes was revealed.The study conclusions will provide conceptual guidance and consult for design,construction and new technique research of the cutting slope protection.

1.0 Introduction Hypertext technology still continues to excite many, ever since it became popular in the late 1980s. Many people then were sceptical that the technology might just be a passing fad. However, there are some who think that the promise behind hypertext is too fundamental to disappear quickly, and there are reasons to believe that hypertext technology promises something special. In hypertext, users not only benefit from the information they read but also from the richness of associations supported by the network of nodes and links. Hypertext has affected us directly, or indirectly in almost every facet of our lives, ranging from scientific work to business and education needs, to our general way of life. Take for example the World Wide Web (WWW) on the Internet. By the end of 1994, it has an estimate of 30 million users (Nielsen, 1995). However, hypertext is not a pancrea to life's problems (Nielsen, 1995). Associated with hypertext are two classes of problems (Conklin, 1987): problems with current implementations, which include delays in the display of referenced materials, deficiencies in browsers, etc.; and secondly, problems that seem endemic to hypertext such as cognitive overload and disorientation. Cognitive overload is the additional effort and concentration necessary to maintain several tasks or trails at one time. Disorientation is the tendency of users to lose their way in non-linear information. This is commonly referred to as the "lost in hyperspace" (LIH) problem.


This application note demonstrates the productivity performance of the Agilent 1290 Infinity LC coupled to the Agilent 6460A Triple Quadrupole LC/MS. The following will be shown: • Use of dried blood spot (DBS) technology to extract a cassette of pharmaceuticals from merely 15 μL of full blood • High speed chromatography / MS at column back pressures approaching 1,200 bar using a novel ZORBAX Rapid Resolution High-Definition (RRHD) sub-2 μm particle column • High quality separation of a cocktail of seven small molecule drugs in less than 50 sec • High-end detection sensitivity Authors Stephan Buckenmaier Agilent Technologies R&D and Marketing GmbH & Co. KG Waldbronn, Germany Keith Waddell Agilent Technologies, Inc. Santa Clara, CA USA Application Note Dried Blood Spot (DBS) technology7-10 was used to extract the cassette from small volumes of whole blood. DBS offers advantages over traditional plasma sampling for pre-clinical and clinical assays. For example, in pre-clinical laboratories, the reduced volumes of blood needed to prepare DBS samples allows serial bleeding of a reduced number of rodents, which aids overcoming inter-individual variations. This could improve the quality of PK data in addition to the related ethical and cost benefits.

Migrant populations (defined as foreign-born) in the EU/EEA may be one of several under-immunised populations yet their role in outbreaks of vaccine-preventable diseases (VPDs) has been poorly defined to date. In this talk, SH will summarise our current understanding of the problem and explore implications for heath systems in Europe, policy, and practice in light of new ECDC guidelines detailing approaches to vaccination in recently arrived migrants to Europe.


Despite the growing body of research on speech prosody, there is still a restricted amount of information available about the acquisition/learning process of prosodic phenomena (stress, accent, tone, rhythm, intonation) in a second/foreign language (L2). This holds true for both non-native speakers' production and perception of prosody. In this respect, there has been – and still is – a longstanding debate in the literature about the potential benefit of music education in the L2 acquisition of prosody. Although recent treatments provide some positive evidence for the existence of a link between music and (various aspects of) "prosodic proficiency" in an L2 – thereby pointing towards a potential advantage for musicians over non-musicians – more research is needed to assess this relationship with regard to a wide(r) range of prosodic phenomena and/or learning contexts. So, to our knowledge, no research has been done so far on (non-)musicians' perception of prosodic prominence in an L2.


This study is aimed at revealing the contributions of microblogging services to user satisfaction in China. An empirical investigation was conducted to analyse user experience on the 36 main microblogging service elements, using a sample of 216 users of Sina Weibo, which is the biggest microblog in China. The tetra-class model was then applied to identify the contribution of each service element to the overall satisfaction. Through correspondence analysis, we calculated, respectively, the contribution to dissatisfaction when the service element was negatively evaluated and that to satisfaction when it was positively evaluated. Based on these two contribution values, we classified the service elements into four categories: Basic, Secondary, Plus, and Key. In order to know the preferences of different users towards the microblogging service elements, we segmented the users into groups according to their microblogging characteristics and personal attributes and then discussed the variations of the service, categorising among different user groups. Finally, we analysed the results and reached some conclusions, which could be helpful for the improvement of customised microblogging services.


For high concrete faced rockfill dam,the grain crushing is so large in high stress field which may increase the deformation rate of dam body that it should be considered in numerical calculation. Because the traditional constitutive model for rockfill material can not reasonably reflect the effects of grain crushing,the calculation deformation of dam body is much different from its measured deformation. Tianshengqiao CFRD (concrete faced rockfill dam) is the first 200 m class high dam which has abound observation date in the similar of type built dam in China. Based on binary medium model considering grain crushing of rockfill material,the stress-strain behavior of dam body is analyzed by planar finite element method(FEM). Because the dilatancy quantity of dam materials will decrease and their corresponding shrinkage quantity will increase when the grain crushing is considered in numerical calculation,the calculation results of the suggested model is more accurate in qualitative analysis and more reasonable in quantitative analysis. It could be better to be used simulate stress-strain behavior of CFRD,especially high CFRD.

Unstable pelvic ring injuries continue to be challenging to manage. Obese patients have a higher risk of complications and such management entails additional difficulties for emergency services and the medical-surgical team. A 41-year-old male with a body mass index of 44 fell from a water slide and suffered an anteroposterior pelvic compression impact injury. He presented with a Tile C1.3 pelvic fracture, Denis III sacral fracture, and Roy-Camille Type 4 spinopelvic dissociation. We performed a posterior triangular fixation and anterior double plating, and the patient gained full recovery and was able to return to work. This case report focuses on some key tools and techniques to consider when managing complex pelvic fractures in obese patients, requiring specialized equipment or adjustments to conventional treatments to obtain a good outcome. We used accessory portals through the fat pad to adequately place the plate screws. In addition, we used polypropylene mesh for post-operative incisional hernia prophylaxis, longer instruments for iliosacral screw placement, and a multidisciplinary approach with rehabilitation and nutrition control.

This article examines whether individual differences in preference for consistency (PFC) affect the behavioral change in the induced-hypocrisy paradigm. Undergraduate students (N = 108) completed the PFC scale either 1 month (no PFC-focus condition) or immediately before (PFC-focus condition) the induced-hypocrisy procedure; this procedure includes pro-social advocacy, transgression recall, and a behavioral change measure. Results demonstrated (1) that PFC-level predicts behavioral change only when the participants were focused on their own PFC and (2) a relationship between the number of recalled transgressions and behavioral change only for high-PFC participants in PFC-focus condition. The necessity of considering simultaneously PFC-level, PFC-focus, and the number of recalled transgressions to better predict behavioral change in the hypocrisy-paradigm, is discussed.

ABSTRACT: Eleven physical therapy programs located at liberal arts institutions were studied to determine the extent to which they were integrated into their institutions. Three phases of data collection were used: 1) review of institutional and program documents, 2) analysis of programinstitution fit as measured by a mailed survey completed by 512 physical therapy students and 57 physical therapy faculty at the liberal arts institutions, and 3) on‐site visitation of one school at each end of the program‐institution fit continuum. Results showed that I) physical therapy students and faculty believed their educational values to be similar to those of others at the institutions, and 2) despite similar values, varying degrees of physical therapy student and faculty isolation from their institutions were common. Conclusions were that the operation of physical therapy programs at liberal arts institutions can be accomplished without excessive compromise of either the liberal arts mission of the institution or the professionalism of the program. The most significant strategy for accomplishing the melding of the two different types of education appeared to be the placement of physical therapy education after liberal arts education, rather than substitution of professional preparation for a broad base of general education.


Many lncRNAs are elevated and downregulated in osteosarcoma (OS) cells. These RNAs are involved in a variety of biological processes, including angiogenesis, metastasis, cell signaling, autophagia, and death. In this paper, we give a concise rundown of the lncRNAs that are abnormally expressed in CDDP-resistant OS cell lines. The manipulation of influx/efflux transporters, apoptosis escape, interference in DNA repair mechanisms, autophagy triggered by therapy, and the control of cell signaling pathways appear to be essential mechanisms implicated in the chemoresistance of CDDP mediated by lncRNAs. Overexpression of LNC-ROR, OIP5-AS1, NCK-AS1, and NORAD increases drug efflux transporter activity, whereas overexpression of ANRIL and DNAJC3-AS1 and downregulation of NEAT1, LINC00161, and LINC00473 lowers apoptotic activation. Furthermore, elevated levels of SNHG16 are linked to autophagy induction, whereas overexpression of MIR17HG, TTN-AS1, and KCNQ1OT1 is linked to DNA damage repair and cell cycle dysregulation. Finally, Wnt/-catenin modulation is linked to overexpression of MSC-AS1, TUG1, HOTTIP, and OIP5-AS1, and PI3K/AKT promotes OS cancer cell chemoresistance. When taken together, these findings are expected to lead to a better understanding of CDDP chemoresistance in OS patients as well as improved therapeutic options.


In the following close reading of Georg Simmel's "How Is Society Possible?" (1910), I have chosen to disregard both the secondary literature on this essay and the various philosophical systems that interested Simmel while writing it to attain a fresh perspective on the text itself and the stakes that it raises. I hope to clarify how Simmel is inspired by a notion of the "outside" and to hint at how a similar concept will become central, more than a half century later, to poststructuralism. In analyzing an irreducible "in-addition" that belongs to the individual but remains independent of all attempts to socialize him or her, Simmel's essay contains, for the first time, a philosophical elaboration of the primacy of the outside to society, over the "inside" of society, that inspired thinkers like Gilles Deleuze and Michel Foucault. Giving substance to the idea that resistance to power is irreducible to a force that is merely reactive, Sim mel's text presented, almost a century ago, an alternative way of thinking or, rather, a way of thinking the alternative that has lost none of its relevance.


Immigration trends in the United States necessitate the preparation of new K-12 teachers to teach diverse populations and to recognize the capabilities of immigrant and refugee children. Transformative learning that results from service learning offers a promising opportunity for preservice teachers to gain awareness and change their attitudes toward these children. This study examined the role of service learning where undergraduate education students tutored at a local refugee agency or elementary school. An analysis of their journal entries indicated changes in beliefs and attitudes toward refugee and other immigrant children, including the acknowledgement of their motivation and determination when confronted by challenges not faced by students born in the United States.


This study employs several methods to simulate and construct the portfolio from stock indexes of the six Association of Southeast Asian Nations (ASEAN) markets during the period from January 2001 to December 2017, namely, time-varying Copulas; Glosten, Jagannathan and Runkle (GJR); generalised autoregressive conditional heteroskedasticity (GARCH); extreme value theory (EVT); and conditional value at risk (CVaR). Our target is minimising the risk based on CVaR, then achieving the maximal expected return for investors. Our model also sheds further light on the role of the dependence structure among stock indexes by employing elliptical (student t) Copulas, which are incorporated for simulating the optimal portfolios. Our findings suggest that the investor should invest in the optimal portfolio, which lies in the efficiency curve. Hence, the optimal portfolio has similar time-varying characteristics across the dependence of Copulas, as well as confidence levels. The research implications can be employed practically by portfolio managers and individual investors who desire to invest in ASEAN equity markets. Therefore, our findings can draw investors' attention to constructing the portfolio with the dependence level via time-varying Copulas and minimise the risk represented by CVaR rather than traditional variance.


This study focused on the analysis of availability and utilization of instructional facilities in Public secondary schools in Port Harcourt Metropolis. The study adopted the descriptive survey design with a total of thirty five (35) senior secondary schools which comprises of 35 administrators (principals) and one thousand nine hundred and fifty four (1,954) teachers, which six hundred and two (602) are male and one thousand, three hundred and fifty two (1,352) are female. A sample size of twenty (20) schools and 420 respondents were drawn from the population using simple random sampling technique. The instrument used to collect data for the study was a self constructed questionnaire tagged "Availability and Utilization of Instructional Facilities Questionnaire". The instrument was administered to both administrators and teachers after validation was done by the Supervisor and two experts in the Department of Educational Management, Rivers State University, Port Harcourt; while the reliability was determined using Cronbach Alpha method that yield the reliability index of 0.62 and 0.60 for each participant respectively. Data were analyzed using Mean and Standard Deviation to answer the research questions while independent sample t-test was used to test the null hypotheses. The findings revealed that there is no significant difference between the administrators and the teachers among the variables in the study; availability of instructional facilities tcal = -2.036, at 0.055 > 0.05, utilization of instructional facilities tcal = -.542 at 0.594 > 0.05, factors affecting the availability of instructional facilities tcal = 1.340 at 0.690 > 0.05 and factors affecting utilization of instructional facilities tcal = .622 at 0.541 > 0.05. Amongst others, it was recommended that the government should endeavour to provide instructional facilities in these schools to improve teaching learning process, due to the significance of these instructional facilities in the educational system; the government should organize seminars/workshops so that the teachers will be computer compliant as to effectively adapt to innovative teaching methods using digital instructional facilities and school administrators should endeavour to assist in pressuring the government in the provision of instructional facilities, due to it's significance in the teaching and learning process.

In the context of object detection, sliding-window classifiers and single-shot convolutional neural network (CNN) meta-architectures typically yield multiple overlapping candidate windows with similar high scores around the true location of a particular object. Non-maximum suppression (NMS) is the process of selecting a single representative candidate within this cluster of detections, so as to obtain a unique detection per object appearing on a given picture. In this paper, we present a highly scalable NMS algorithm for embedded graphics processing unit (GPU) architectures that is designed from scratch to handle workloads featuring thousands of simultaneous detections on a given picture. Our kernels are directly applicable to other sequential NMS algorithms such as FeatureNMS, Soft-NMS or AdaptiveNMS that share the inner workings of the classic greedy NMS method. The obtained performance results show that our parallel NMS algorithm is capable of clustering 1024 simultaneous detected objects per frame in roughly 1 ms on both Tegra X1 and Tegra X2 on-die GPUs, while taking 2 ms on Tegra K1. Furthermore, our proposed parallel greedy NMS algorithm yields a 14–40x speed up when compared to state-of-the-art NMS methods that require learning a CNN from annotated data.


Data mining of existing radiology and pathology reports within an enterprise health system can be used for clinical decision support, research, education, as well as operational analyses. In our health system, the database of radiology and pathology reports exceeds 13 million entries combined. We are building a web-based tool to allow search and data analysis of these combined databases using freely available and open source tools. This presentation will compare performance of an open source full-text indexing tool to MySQL's full-text indexing and searching and describe implementation procedures to incorporate these capabilities into a radiology-pathology search engine.


Abstract : Trained military air traffic controllers report increased anxiety following, and demonstrate increased heart rate and urinary levels of epinephrine during a session of ground control interception. This type of activation has not detrimental effects on health, and is probably necessary for efficient performance even in well trained and coping personnel. There was also some rise in plasma levels of cortisol, but no other endocrine signs of any general activation. However, if the coping potential of the men is threatened, in a real life situation, the activation picture is expected to be totally different, with a general activation which is far more taxing both on the information treating capacity and on the brain biochemistry. Psychological defense mechanisms will then be activated, which also impede performance. These physiological and physiological mechanisms are difficult to mimic, and occur only when the individual feels a real danger and threat to his or her coping potential.


An automatic speed change control / regulating device with a constant speed driving mode which can transmit torque to wheels of a vehicle in accordance with changes of the traveling load of the vehicle, even if a gear-shift mode is changed to the manual gearshift mode. When the manual gearshift mode is set as a gear shift mode and a constant speed drive mode is set as the drive mode, a constant-speed running control / regulating means generates a downshift command signal. In this case, the gear-change stage of the automatic transmission is shifted down when the accelerator pedal is depressed beyond a predetermined amount addition.


If leprosy is not handled carefully, it can cause disabilities and conditions become an obstacle for leprosy patients in living their social life. The existence of disabilities in lepers causes physical changes to the sufferers. The changes in leprosy sufferers can become stressors that affect self-concept. The purpose of this study was to determine the effect of disability and stigma on self-concept in leprosy patients. The research design used was correlation analysis with cross sectional data collection. The population was all leprosy patients in the outpatient installation of the Daha Husada General Hospital with a total sample of 50 respondents who were selected using the purposive sampling technique. Measurement of disability is developed from the standard provisions of the Ministry of Health of the Republic of Indonesia. Stigma measurement uses the Internalized Stigma of Mental Illnes Scale (ISMI) which was developed by The International Federation of Anti-Leprosy Associations (ILEP) in 2011. Meanwhile, the Self-Concept instrument is developed from indicators according to theory. The analysis used was logistic regression starting with the examination of the variables and the results were p value = 0.40 for disability and p value = 0.49 for stigma. It can be interpreted that disability gives potential 5,652 times and stigma gives potential 6,205 times for self-concept.

The diving is a standalone activity held in wild environment. There are indications that psychological factors influence and are influenced by physical activities, creating therefore influence over the operation of diving. This research was aimed at mapping out the psychological profile of divers standalone during their performance in order to better understand what type of individual is dedicated to the activity. For the analysis of this profile, was used an inventory developed by Loehr (1982) and validated by Raposo (1993) which aims to identify seven psychological variables of performance through the 42 questions that are answered in a kind likert scale of 5 points. In descriptive analysis of the psychological variables has been observed: self confidence (25,90 ± 2,62); Control of negativism (21,63 ± 1,62); Focus atencional (19,09 ± 2.19); View (17,11 ± 2,27); motivation (23,47 ± 2,83); good thoughts (18,97 ± 2,03); attitude competitive (21,63 ± 2,22). The strongest feature of the personality of individuals in the group was a self confidence.


Giant cell tumour of bone (GCT) is a relatively rare benign bone tumour more frequent in young people (20–40 years). Histologically, two cell types are represented, stromal cells of osteoblastic origin and a distinctive osteoclast-like population probably of monocytic origin. GCTs can be aggressive and they recur locally in up to 50% of cases; up to 5% of GCTs metastasise to the lungs and spontaneous transformation to a high-grade malignancy occurs in 1–3% of patients. The aetiology of GCT is not known, and no risk factors have been recognised, although familial clustering of both Paget's disease and GCT has been reported.GCTs account for approximately 3–5% of primary bone tumours. GCT is rarely multicentric and usually occurs at the epiphyses of long bones, but may also affect other bones.There are few randomised, prospective clinical trials available to guide clinical management of GCT. Recent developments have led to evaluation of newer therapeutic agents, including biphosphonates and denosumab, with encouraging results. We report the case of a 66-year-old woman affected by GCT. In 1985 the patient, then 41 years old, presented a cystic lesion on her left tibia, which was removed surgically. This lesion relapsed two years later. Therefore the patient was hospitalised and received a diagnosis of "multicentric giant cell bone lesions" (limb-girdle, sternum, mandible, ribs), confirmed by histological examination. These lesions showed hyperactivity on bone scintigraphy. Plain radiographs demonstrated destructive lytic lesions. Blood and urinary examinations showed markedly elevated levels of bone alkaline phosphatase and urine pyridinoline and there was persistent bone pain. In 1993 normocalcaemic primary hyperparathyroidism was diagnosed and an adenoma was removed, with no relapse of the disease. Subsequently the patient started clodronate therapy, i.v., followed by alendronate-neridronate per os and clodronate i.m. for about nine years. Biphosphonate therapy caused a modest and transient decrease in bone indexes. Initial bone lesions were unchanged on computed tomography 25 years after diagnosis, but new bone lesions had appeared. MEN1 gene and CasR analyses were negative.This is a rare case of a patient affected by multicentric giant cell tumours with a 25-year follow up. A slow progression of the lesion is documented, as well as the absence of significant effect of biphosphonate therapy.


Background/Objectives: Images are the most effective way of revealinginformation to the world. Images are analysed and processed by computerized techniquesto extract hidden information available in it. Innumerable techniques are available to process the images. In numerous fields, the processed images are used for decision making. In medical field, automated detection and quantitative analysis of the radiological images and other images are processed by Computer Aided Diagnosis(CAD) tool to detect the abnormalities present in images. Methods/Statistical Analysis:Segmentation is one of the techniques used in CAD which play a vibrant role in processing the images. It is a process in which regions/ features sharing related characteristics are recognized or grouped together to interpret the images. Each segment divulges some information to the users. Segmentation techniques vary from image to image and areapplied to the images depending upon the problems being solved.This research work analyses about the segmentation techniques which are used in medical field. Findings: The results of the various research papers are discussed based on the approaches of hybrid algorithms applied in segmentation techniques. Also, this research work analyses about theuse of various segmentation techniques applied in mammogram images using CAD tool which assist the radiologist to interpret the suspicious regions and to know the impact of the diseases in patients for the suitable prediction. Application/Improvements: The segmentation techniquesare implemented to analyse mammogram images in future by means of a practical approach.


SummaryA survey has been carried out to study the occurrence and distribution of Trichodorus primitivus, T. sparsus and T. viruliferus in the Czech Republic under the rhizosphere of orchards, forests, vineyards and strawberry. Total 208 sites were surveyed and only 29 sites were found positive for these species. All three species are reported in the Czech Republic for the first time.


Abstract We know very little about today's stay-at-home mother couples because the majority of research was conducted in the 1960s and 1970s with only a few studies in the early 1980s. Given the many advances by women toward equal rights, the increasing awareness of the importance of equality in marriages, and a movement by men to be more involved with their children, we would expect these "modern traditional" families to look different than in previous decades.


Video-based automatic assessment of a student's learning engagement on the fly can provide immense values for delivering personalized instructional services, a vehicle particularly important for massive online education. To train such an assessor, a major challenge lies in the collection of sufficient labels at the appropriate temporal granularity since a learner's engagement status may continuously change throughout a study session. Supplying labels at either frame or clip level incurs a high annotation cost. To overcome such a challenge, this paper proposes a novel hierarchical multiple instance learning (MIL) solution, which only requires labels anchored on full-length videos to learn to assess student engagement at an arbitrary temporal granularity and for an arbitrary duration in a study session. The hierarchical model mainly comprises a bottom module and a top module, respectively dedicated to learning the latent relationship between a clip and its constituent frames and that between a video and its constituent clips, with the constraints on the training stage that the average engagements of local clips is that of the video label. To verify the effectiveness of our method, we compare the performance of the proposed approach with that of several state-of-the-art peer solutions through extensive experiments.

ABSTRACT Microelectromechanical systems (MEMS) devices have been increasing in popularity for radio frequency (RF) and microwave communication systems due to the ability of MEMS devices to improve the performance of these circuits and systems. This interdisciplinary field combines the aspects of lithographic fabrication, mechanics , materials science, and RF/microwave circuit technology to produce moving structures with feature dimensions on the micron scale (micro structures). MEMS technology has been used to improve switches, varactors, and inductors to name a few specific examples. Most MEMS devices have been fabricated using planar micro fabrication techniques that are similar to current IC fabrication techniques. These techniques limit the thickness of individual layers to a few microns, and restrict the structures to have planar and not vertical features. One micro fabrication technology that has not seen much application to microwave MEMS devices is LIGA, a German acronym for X-ray lithography, electro-forming, and moulding. LIGA uses X-ray lithography to produce very tall structures (hundreds of microns) with excellent structural quality, and with lateral feature sizes smaller than a micron. These unique properties have led to an increased interest in LIGA for the development of high performance microwave devices, particularily as operating frequencies increase and physical device size decreases. Existing work using LIGA for microwave devices has concentrated on statically operating structures such as transmission lines, filters, and couplers. This research uses these unique fabrication capabilities to develop dynamically operating microwave devices with high frequency performance. This thesis documents the design, simulation, fabrication, and testing of MEMS …


ABSTRACT
This study investigated the effects of drying temperature (40-60
o
C) and starch inclusion
level (10-30%) on selected functional properties of starch-albumen powder (SAP). The two
independent factors at five levels each were combined to make a total of 13 experimental
runs using a central composite rotatable response surface design with 5 central points. The
effect of SAP and its reconstituted form (RSAP) as coating material on the quality of
coated fried yam chips was also investigated. The moisture content (MC), water absorption
capacity (WAC) and oil absorption capacity (OAC) of the SAP were determined. Also, the
MC, oil uptake (OU), colour parameters describing lightness (L*), redness (a*) and
yellowness (b*) as well as sensory acceptability of coated fried yam chips were also
determined. The response data obtained on the properties of SAP and fried chips were fitted
to a quadratic nonlinear regression model. Means of determinations were analyzed using
one-way analysis of variance (ANOVA) at 95% confidence level and were separated using
Duncan's Multiple Range Test. The MC, WAC and OAC of the SAP ranged from 4.56 to
7.87%, 1.04 to 1.33 g/g and 0.86 to 1.18 g/g, respectively. The quadratic regression mo dels
generated for predicting MC and WAC of the SAP had about 75 to 89% accuracy. The
values of MC (27.18 - 44.23%) and OU (16.47 - 30.21%) in yam chips coated with SAP
were lower compared with MC (31.75-59.15%) and OU (19.83-33.71%) of samples coated
with RSAP. The degree of accuracy of the regression models for predicting the MC and
OU of chips coated with SAP (90-94%) was however, higher than for RSAP (45-75%).
Increased starch content of the coating materials resulted in light er chips (p 0.05; b*, r= 0.717, p<0.01). It is noteworthy that samples
coated with RSAP had significantly higher OU and MC than that coated with SAP. The
optimum drying temperature and starch inclusion to achieve multiple objectives of
minimizing the MC, OU and maximizing product acceptability with SAP and RSAP
coatings were 40
o
C and 46
o

This article deals with an important for sexology and psychiatry issue of classification of sexual disorders. On basis of comparative analysis of previous classifications and own experience of using the ICD-10, the authors point to a number of drawbacks in this classification system and formulate grounds for changes in the ICD-11. They propose to collect all sexual disorders in one cluster, to reconsider diagnostic criteria for transsexualism, to replace the term 'preference' with 'orientation', to introduce the items 'disordered psychosexual development', 'postorgasmic disorders', 'sexual disharmony', to split 'pedophilia' and 'ephebophilia' etc. The authors propose to classify sexual disorders according to phenomenological principle (unlike in the ICD-10), with regard for their character and the mechanism of development. The authors raise the issue of professionals' strategy while dealing with persons with ego-dystonic sexual orientation who seek help.


A classical result of Philipp (1975) states that for any sequence (n k ) k ≥1 of integers satisfying the Hadamard gap condition n k+1 /n k ≥ q > 1 (k = 1,2,...), the discrepancy D N of the sequence (n k x)k≥1 mod 1 satisfies the law of the iterated logarithm (LIL), i.e. 1/4 ≤ lim sup ND N (n k x)(N log log N) -12 ≤ C q a .e. N→∞ The value of the lim sup is a long-standing open problem. Recently Fukuyama explicitly calculated the value of the lim sup for n k = θ k , θ > 1, not necessarily integer. We extend Fukuyama's result to a large class of integer sequences (n k ) characterized in terms of the number of solutions of a certain class of Diophantine equations and show that the value of the lim sup is the same as in the Chung-Smirnov LIL for i.i.d. random variables.

AGGARWAL, SACHIN. An Inviscid Numerical Method for Unsteady Flows over Airfoils and Wings to Predict the Onset of Leading Edge Vortex Formation. (Under the direction of Dr. Ashok Gopalarathnam.) A numerical method based on distribution of discrete vortex elements for unsteady motions of two-dimensional airfoils and three-dimensional wings is developed. The main objective was to determine the onset criterion for formation of leading edge vortices. The objective of this research effort is to find a parameter in the numerical model that is similar to the leading edge suction parameter (LESP) that has been developed in recent theoretical work and compare the results from this numerical model with the previously-developed theoretical model, computations and experiments. It is shown that the strength of the forward-most discrete bound vortex has a behavior that is very similar to the LESP, and can be used as a proxy for the LESP. Results from this model are shown to match with those from the theoretical model and for a range of pitch and plunge motions. Thus the numerical model can be used instead of the theoretical model to study unsteady motions and predict the onset of LEV formation during these motions. The advantage of the numerical model is that it can be easily extended to three-dimensional wings and rotor shapes. An extension to the LESP criterion to three-dimensional wing and rotor analysis using unsteady vortex lattice method is carried out. Results from this extended model are shown to be a very good match with results in the literature for some steady and unsteady motions. The numerical method was also used to study two pitching motions for a finite wing of aspect ratio 2, with pivot points at the quarter-chord and three quarter-chord locations. In both cases, comparison of LEV onset with CFD results from a companion research effort shows that the low-order method predicts the spanwise location for the onset of LEV formation correctly and predicts the angle of attack for LEV onset within 1 degree of the CFD result. In both cases, the numerical method over-predicted the angle of attack for LEV onset by 1 degree. This good agreement shows that the overall approach for the numerical method is correct. The cause for the small discrepancy needs to be determined in future efforts. © Copyright 2013 by Sachin Aggarwal All Rights Reserved An Inviscid Numerical Method for Unsteady Flows over Airfoils and Wings to Predict the Onset of Leading Edge Vortex Formation


This paper offers a longitudinal analysis of the relationship between marriage and leaving the agricultural sector [in France] using data published by INED [Institut National dEtudes Demographiques] in its biographical survey of family work and migration. The strategies of the two sexes seem to differ: whereas leaving agriculture has no influence upon a womans chances of marriage marriage within this sector confines her to the land. Mens chances of marriage however are doubled if they leave the agricultural sector. Yet their marital status scarcely influences their decision to leave agriculture. Various characteristics of these individuals are presented to illustrate these strategies. (summary in ENG SPA) (EXCERPT)


*** Mr. Wheeler's letter gives us an opportunity of meeting an antivaccination argument on its own ground entirely-one that is seldom granted, by reason of the side issues so often raised. First, as regards the large number of small-pox deaths of late in Birmingham, we may state that in the recent epidemic there were in this admittedly " well-vaccinated population" only two fewer deaths in the unvaccinated minority (75) than in the major portion of the (well-vaccinated) community. Now, if we only allow 90 out of each 100 of population to have been vaccinated, then the 75 deaths in unvaccinated persons should have been not quite 8. On the other hand, had the vaccinated nine-tenths of the population suffered in the same proportion as the unvaceinated we should have seen, not 77, but 675 deaths amongst them. In respect of the mortality-rates in the two classes of sufferers, the epidemic of last year showed that, whereas there were in each 1,000 of vaccinated patients 44 deaths, there were no fewer than 335 in each 1,000 of unvaccinated patients. We need Eay no more under this head. On the subject of insanitary conditions having had a preponderating influence on small-pox epidemicity in both Birmingham and Sheffield, we propose to look at the matter in each place separately. First, as to Birmingham, the published data enable us to contrast sanitation and small-pox in only one special particular, namely, on the score of the means at hand for the storage and removal of excremental filth. Dr. Hill has drawn attention to the persistence of the foul ashpit and other forms of privies in the city, all of the nineteen districts into which it is divided baving these abominations in greater or less degree. All these nineteen districts had also small-pox attacks in greater or less degree. Proceeding to record for each and every district the number of houses-populations not being accessible -the number of privies, and the small-pox attacks in 1894; and then the rate per 1,000 houses of both privies and smallpox attacks; and going on further to look upon the rates for the whole city in each case (privies and small-pox) as 100, we have, in addition, set down in the table herewith what is the relation of privy and small-pox prevalence in each district to the entire city. BRMINGIEAM: 1891.


the Lord's Prayer. The reasons for this are not at all obscure. For one thing, the passage thrusts itself out from the Corinthian letter as if to invite special attention. Secondly, the chapter forms a neat, self-contained literary unit, dealing concisely with the theme of love. Thirdly, the theme meets people on a level which they can understand (or think they can understand) while the more complicated theological constructs of Paul do not. And finally, the theme of love is expressed in noble literary form, making its retention in the memory easy. These factors, which make the passage so conspicuously different from the mass of Pauline material, suggest the possibility that the chapter is an interpolation. This paper is an examination of this possibility. Two points need to be made clear at the outset. First, Pauline authorship would not be disproved by a demonstration that the passage is out of context in its present position. In the second place, to deny the hymn on love to Paul is not to deny that he gave love an important place in his thought. In Galatians 5:14 he says that the whole law is fulfilled in one word: "You shall love your neighbor as yourself." This is reiterated in Romans 13:10. Again, in I Corinthians 8:1 he states that "knowledge puffs up, but love builds up." It is clear, without laboring the point, that an argument against the authenticity of the passage must be made on other grounds than a denial of the importance of love in Paul's thought. The fact that the genuineness of I Corinthians 13 has had almost universal support from critical scholarship must cause us to exercise caution in assertions to the contrary. The following argument, if it has any weight at all, must be in its cumulative effect, and not in a single point in isolation. 1. A general but nonetheless pertinent observation is that Paul's letters were at some

Some of the CRSwNP patients are relatively well managed without recurrences while others are difficult due to recurrence and refractoriness after surgical or medical treatment. Thus CRSwNP is not a single disease but is rather considered as a disease that has a variety of disease spectrum. Various biomarkers have been proposed to distinguish endotypes of CRSwNP. CRSwNP with high tissue eosinophil infiltration with robust type 2 inflammation (e.g., IL-5) is usually associated with comorbid asthma and is likely to recur. This type of CRSwNP is relatively common in Western countries. However, in Asian countries, CRSwNP is often presented as a heterogeneous disease comprising a mixture of type 1 (e.g., IFN-γ), type 2 and type 3 (e.g., IL-17) inflammation. In Asians, up-regulation of IL-8, IFN-γ and associated neutrophilic inflammation is prone to have disease refractoriness. Different underlying inflammatory profile indicates different underlying pathogenesis. Therefore, in the era of precision medicine, treatment should be based upon according to endotype.

This thesis is devoted to the Earth Mover's Distance and its use within content-based image retrieval (CBIR). The major CBIR problem discussed is the pattern problem: Given an image and a query pattern, determine if the image contains a region which is visually similar to the pattern; if so, find at least one such image region.
The Earth Mover's Distance (EMD) is an edit distance between distributions that allows for partial matching, and which has many applications in CBIR. We give a couple of modifications which make the EMD more amenable to partial matching, including the partial EMD in which only a given fraction of the weight in one distribution is forced to match weight in the other.
An important issue addressed in this thesis is the use of efficient, effective lower bounds on the EMD to speed up retrieval times. We contribute lower bounds that are applicable in the partial matching case in which distributions do not have the same total weight.
Another important problem in CBIR is the EMD under transformation (EMD G ) problem: find a transformation of one distribution which minimizes its EMD to another, where the set of allowable transformations G is given. The problem of estimating the size/scale at which a pattern occurs in an image is phrased and efficiently solved as an EMD G problem.
For EMD G problems with transformations that modify the points of a distribution but not its weights, we present a very general, monotonically convergent iteration called the FT iteration. This iteration may, however, converge to only a locally optimal EMD value and transformation. We also present algorithms that are guaranteed to find a globally optimal transformation when matching equal-weight distributions under translation.
Our pattern problem solution is the SEDL (Scale Estimation for Directed Location) content-based image retrieval system. Three important contributions of this system are (1) a general framework for finding both color and shape patterns, (2) the previously mentioned novel scale estimation algorithm using the EMD, and (3) a directed (as opposed to exhaustive) search strategy. We show that SEDL achieves excellent results for the color pattern problem on a database of product advertisements, and the shape pattern problem on a database of Chinese characters.

The role of chemicals cues in host location by the parasitoid Dinarmus basalis (Rond.) was investigated in bioassays by measuring response to stimuli associated with one of its hosts, the larvae of beetle bruchid, Bruchidius atrolineatus (Pic.) infesting Vigna unguiculata (L. Walp.) seeds. Orientation of parasitoid females was measured in response to stimuli from non host-plants: ( Pennisetum typhoides (Burm.) and Sorghum bicolo r (L. Moench), host-plant (cowpea) and plant-host complex. The results showed that D. basalis females were not attracted by stimuli from non host-plant but they were significantly oriented towards stimuli emanating from young host plant of V. unguiculata in vegetative stage and host-plant complex. Infested pods were more attractive than the healthy pods. © 2010 International Formulae Group. All rights reserved. Keywords: Bruchidius atrolineatu s, chemicals cues, Vigna unguiculata .


LOCKSS marries age old concepts of librarianship with modern technology

Information stored on paper can survive for millennia; information stored digitally today may not be recoverable this time next week. With seven million pages of new information added to the world wide web each day, the volatility of websites has emerged as an urgent problem, especially as websites are becoming the version of record for scientific journals. Three studies of links in peer reviewed journals all found their useful life to be a few …


In the paper there is studied dynamic interaction between electromechanical parts of the precise micro-drive system driven by the hybrid stepping motor which is a source of torsional vibrations. Since in such a case a possibly exact rotational motion of the mechanism must be assured, it is necessary to use sufficiently accurate models of the drive system and the electric motor, where dynamic electromechanical coupling effects are going to be taken into consideration. So that models are presented. From the computational results it follows that there is observed a significant influence of the electromechanical coupling on the dynamic behavior of the drive system driven by the stepping motor.


Vlhorf claims that any thought process takes place within the boundaries of a language, that each language fleshes out a worldview and that the world views structured by languages or, at least, the language families 'differ greatly. Whorf shrouds his view on world views in a metaphysical mystery which makes up the gist of his epistemic paradigm of cultural relativism. The paper sets out to discuss some of the tenets and conclusions of Whorfs views, unveiling their traces into the contemporary linguistics and philosophy and expounds Whorf's staunch relativistic creed, reviews the arguments against his position and appraises the arguments for a soft version relativistic version of the theory. We call aftermath the array of positions taken up by those who prove and disprove linguistic relativism alike. The author of the paper sets forth his own soft version of linguistic relativism called perspectivism, which permeates the entire linguistic field and is tightly linked up with cognition and cognitive paradigm approaches.


In this paper, we investigate the eco-epidemiological model with impulsive perturbation. Using Floquet theory and small amplitude perturbation method, we prove that the boundary periodic solution is asymptotically stable if the impulsive parameter satisfies some conditions. Moreover, the permanence of the system is discussed by analytical method. Finally, the complexity of the system is verified by numerical simulation.


This paper discusses the evolution of television serial drama in China. It argues that Chinese television drama production has progressed through three periods: industrial (1958–89), market (1990–2002), and most recently interpersonal (2003 onwards). These three stages of development are in turn associated with standardised production according to state-directed formulae, outbreaks of producer autonomy, and celebration of modern lifestyles and consumer culture. The paper provides an overview of the development of drama production during these three periods, and notes a shift from 'socialist reality' towards contemporary popular reality.


This article discusses the comparison between the functions and usefulness of safety-critical systems and security-critical systems. The functions of both types of digital systems have become increasingly software intensive and this has contributed to a blurring of the difference between safety and security-critical. (6 pages)


ABSTRACT This study investigated the associations between challenge job demands, job resources, emotional exhaustion and work engagement, and examined the mediation effect of teacher efficacy as a personal resource in the job demands-resources model. The results of a questionnaire survey of 2758 university teachers from 25 universities in mainland China indicated that challenge job demands were positively related to emotional exhaustion and negatively related to work engagement. Job resources were positively related to work engagement and negatively related to emotional exhaustion. Teacher efficacy mediated the effect of challenge job demands and job resources on work engagement. These results have implications for understanding different types of job demands and improving university teachers' well-being, and these implications are identified in this paper.


Streptomycin was one of the major medical discoveries of this century. Tuberculosis could now be cured. No longer had the patient to stay for months in a sanatorium, where cure was by no means certain, even in early cases. Many drugs were tried: creosote was a favourite in early days, apparently because it was excreted by the lungs and had an antiseptic sort of smell. Gold salts were used for quite a long time with no good results. Certain chemical substances allied to sulphanilamides seemed hopeful. Perhaps the most bizarre was insufflation of the bowel with a mixture of carbon dioxide and sulphurated hydrogen. Penicillin proved to be useless. The tubercle bacillus enclosed in a kind of waxy envelope was immune to all these. It could affect not only the lungs but almost any organ in the human body, the brain, the kidneys, the lymph glands, the bones, the joints, even the skin. No wonder Sir William Gull commented on the difficulty in diagnosis.


This investigation is carried out on two groups of patients with corpus alienum corneae. In every group are included 40 patients (40 eyes). For the first group standard treatment is applied after extraction of the corpus alienum corneae using antibiotic drugs (Oftaquix®) and epithelizing gel (Corneregel). First group is used as a control. For the second group of patients immediately after extraction of the corpus alienum corneae, eyes are irradiated for 3 minutes with He-Ne laser (Mediray 04, Optella Ltd., Sofia, Bulgaria) at emission wavelength at 632 nm and power density 0.1 mW/cm2. Second group of eyes is treated with the same drugs as the control group. We observed epithelisation of the damaged cornea in the first group - after 24 hours, and in the laser-irradiated group of eyes significant epithelisation is pronounced the 10th hour after irradiation. Epithelization is proved by fluorescein reaction to detect the eye cornea recovery. The patient eyes of the both groups were investigated under bio-microscope in cobalt-blue illumination. For irradiated eyes by LLLT, we have found that the healing period is shortened significantly by 42 % (p<0,001). Our results revealed that LLLT application is appropriate and perspective for recovery therapy after corpus alienum corneae extraction.
