The amygdaloid nuclei were stimulated by iron deposits or by implanting crystalline carbachol in rats in persistent estrus induced by continuous illumination. Both electrochemical and chemical stimulation produced ovulatory response from the medial nucleus or the basolateral complex of the amygdala. Also, chemical stimulation of the bed nucleus of the stria terminalis was effective in inducing ovulation. Negative responses were observed by stimulating other areas or when the stria terminalis was found to be damaged by the electrode tract. The ovulatory response was blocked by transection of the stria terminalis but not by interruption of the ventral amygdalofugal fibers. Injection of atropine, reserpine or urethane was not effective in blocking ovulation inducedby amygdaloid stimulation. Plasma LH was found significantly higher 5 hr after chemical stimulation of the basolateral amygdaloid complex in ovariectomized rats primed with estradiol benzoate as compared to controls. Also, electrochemical amygdaloi...


Holzer M, Bernard SA, Hachimi-Idrissi S, Roine RO, Sterz F, Mullner M. Hypothermia for neuroprotection after cardiac arrest: Systematic review and individual patient data meta-analysis. Crit. Care Med. 2005; 33: 414–18. This systematic review of relatively small numbers concluded that therapeutic hypothermia in patients who were resuscitated from cardiac arrest improved neurological survival in the short term and also for up to 6 months. The authors note the limitation of only a single trial to demonstrate this. The authors note that these benefits occurred with relatively slow cooling and postulate the benefits might be greater if cooling is more rapid. They note that further research into the area is needed.

CMPisalso aprocess wellsuited forpolishing high-aspect-ratio SU-8structures. Polished PC,PMMA andSU-8surfaces hadnanometer-order surface roughness, acceptable to mostMEMS applications.


A model is introduced with tunable frustration having its origin in topological constraints on a system with purely antiferromagnetic interactions. The average number of spins is maintained within a span extending from pure unfrustrated order to homogeneous random disorder. Examination is by computer simulation and shows evidence of suppression of order as the frustration is increased.


This century's transits of Venus (2004, 2012) captured significant public attention, reminding us that the wonders of astronomy need not be confined to the night. And while nighttime telescope viewing gatherings (a.k.a. "star parties") are perennially popular, astronomy classes are typically held in the daytime. The logistics of coordinating students outside of class can often be problematic, leading to dark-sky activities that are relegated to extra credit for only those who can attend.


The atmospheric correction procedures for space imagery is implied to be in evolving the subsequent approaches in direct problems of atmospheric optics along with finding ways to solve the inverse problems. The direct problems are in using any approximation of the radiation transfer theory to calculate the outgoing radiation field at the top of the atmosphere level with any selected boundary conditions. The inverse problem includes a particular form of the retrieval of parameters characterizing the state of the land cover patterns. Pattern recognition and scene analysis techniques are adjusted to the atmospheric correction procedures for a particular state of the atmosphere for the data of remote sensing surveying the land cover of the region under consideration. The atmospheric optical depth and other characteristics of the atmosphere during the dates of the field campaign are initial to solve the inverse problems using the appropriate radiation transfer improvements.


R.G. Thomson, General Veterinary Pathology. W. B. Saunders Co., Philadelphia-LondonToronto, 1978.444 pages, 561 figures, 23 tables. U.S. $25.00. This book provides the student of veterinary medicine with an introductory text to veterinary pathology, emphasizing general concepts and principles of disease processes. The book is an outgrowth of lecture notes the author used in teaching general pathology to second year veterinary students. The text is organized into seven chapters and four appendices. The first chapter is an introduction dealing with definitions, general terminology and the scope of pathology. Chapters two to seven are discussions of degeneration and necrosis, circulatory disturbances, inflammation and repair, disturbances of growth, neoplasia and host-parasite relationships. The appendices refer to processing and handling of tissues for examination, history of pathology, Greek roots of medical terms and affixes, and objectives of general pathology. Over 800 key references are given separately with each chapter. This book is somewhat less detailed than other available texts of general pathology. It provides the essential background required by the professional curricula of most veterinary schools. The material is well organized and presented in a logical and easily understandable fashion, often simplifying complicated mechanisms for the purpose of easy comprehension by the student. It probably reflects its origin in the classroom more than any other text does. The book is well illustrated; excellent diagrams and sketches have been selected from a variety of sources to further clarify and summarize pathologic processes. These features lead to easier reading and better comprehension. As the author indicates in the preface, more detailed information required by advanced students of pathology has purposely been omitted in order to maintain the primary objective of this book: providing the professional student with a comprehensible text of general pathology. The author suggests additional reading material for more detailed and specific information. Like most one-author texts, this book reflects the inherent bias and personal interests of the author. For example, in a modem text of general pathology more attention should be devoted to radiation injury, since radioactive rays and particles affect the body as a whole and are now and probably will be an important health factor for man and animals. Environmental toxins and poisons are mentioned only briefly; and immunopathology should be expanded. In a future edition, the author might consider changing Chapter 7 to "Host-Agent Relationships" and including physical and chemical agents as well as microorganisms and parasites. Although advantages of simplification in teaching probably outweigh the disadvantages in this book, some categorical statements must be reviewed critically before they are cited since theories and hypotheses change quickly in this age of explosive scientific progress. For example, one essential feature of chemical carcinogenesis is stated to be irreversibility of the effect of carcinogens. It is, however, well documented that DNA damage inflicted by chemical carcinogens can be repaired. The capability to repair such damage may be one of the most important host factors determining resistance to carcinogenesis. Also, personal bias should not conflict with generally accepted disease classifications without further explanation. For instance, the benign tumor of the lymphocytes is termed lymphoma, the malignant tumor a lymphosarcoma. There is, however, no evidence that a benign lymphoma exists in animals, and the expression malignant lymphoma is well established in the most recent human and animal classifications of lymphoid neoplasms.


Kaff Maryam (Anastatica hierochuntica L.) is believed to be very useful in Arab countries for treating various health disorders. The present research highlights the chemical composition and properties of A. hierochuntica L. that may be related to its beneficial effect. Eight minerals (Mg, Ca, Cr, Mn, Fe, Co, Cu, and Zn), the total phenolic content, antioxidant activity, and free radical-scavenging activity were examined in the leaf buds, stem biomass, and root biomass of Kaff Maryam. The plant was found to be a rich source of Mg, Ca, Mn, and phenolic compounds, and had potential antioxidant and free radical-scavenging activities. The findings of the study indicated that the chemical properties of the plant may rationalize its use for the treatment of menstrual cramps, asthma, depression, headache, fatigue, depression, high blood pressure, and infertility problems, and to ease childbirth, as it is used in traditional medicine. Our findings will encourage herbalists to incorporate A. hierochuntica L. in the treatment of various disorders, and this herb could be proved useful in the food industry.

 Key words: Kaff Maryam (Anastatica hierochuntica L.), minerals, phenolic compounds, antioxidant activity, free radical-scavenging activity, traditional herbal medicine.


Heilongjiang province is rich of ice and snow resource considering the long winter,which is a great advantage for winter tourism.However,the analysis upon the tourism market available now as well as the good touring environment tells that the client resource is far less adequate.Based on the analysis of deficiency,marketing strategies are proposed to develop more client resource.


Motion capture (mocap) is rapidly evolving and embraced by a growing community in various research areas. However, a common problem is the high dimensionality of mocap data, and the difficulty to extract and understand meaningful features. In this paper, we propose a framework for the rapid prototyping of feature sets, MotionMachine, which helps to overcome the standard problem of mocap feature understanding by an interactive visualisation of both features and 3D scene. Our framework aims at being flexible to input data format, and to work both offline or in real-time. The design of the feature extraction modules in C++ is intended for modules to be used both for visualisation in the MotionMachine framework and for integration in end-user applications or communication with other existing softwares. We present two examples of use-cases in which the main features of this framework have successfully been tested.


A simple C2-symmetric chiral bisoxazoline is demonstrated to use hydrogen bonding to catalyze an important family of aldol reactions of trifluoroacetaldehyde hemiacetals with various β-carbonyl acids. This reaction is highly enantioselective, delivering chiral nonracemic trifluoromethylated alcohols with excellent optical purity and good isolated yields. This concept of relaying chiral information via a chiral hydrogen-bond acceptor should be applicable to a vast number of organocatalytic processes.


In early diastole, the suction pump feature of the left ventricle opens the mitral valve and aspirates atrial blood. The ventricle fills via a blunt profiled cylindrical jet of blood that forms an asymmetric toroidal vortex ring inside the ventricle whose growth has been quantified by the standard (dimensionless) expression for vortex formation time, VFTstandard = {transmitral velocity time integral}/{mitral orifice diameter}. It can differentiate between hearts having distinguishable early transmitral (Doppler E‐wave) filling patterns. An alternative validated expression, VFTkinematic reexpresses VFTstandard by incorporating left heart, near "constant‐volume pump" physiology thereby revealing VFTkinematic's explicit dependence on maximum rate of longitudinal chamber expansion (E′). In this work, we show that VFTkinematic can differentiate between hearts having indistinguishable E‐wave patterns, such as pseudonormal (PN; 0.75 < E/A < 1.5 and E/E′ > 8) versus normal. Thirteen age‐matched normal and 12 PN data sets (738 total cardiac cycles), all having normal LVEF, were selected from our Cardiovascular Biophysics Laboratory database. Doppler E‐, lateral annular E′‐waves, and M‐mode data (mitral leaflet separation, chamber dimension) was used to compute VFTstandard and VFTkinematic. VFTstandard did not differentiate between groups (normal [3.58 ± 1.06] vs. PN [4.18 ± 0.79], P = 0.13). In comparison, VFTkinematic for normal (3.15 ± 1.28) versus PN (4.75 ± 1.35) yielded P = 0.006. Hence, the applicability of VFTkinematic for diastolic function quantitation has been broadened to include analysis of PN filling patterns in age‐matched groups.


The National Academies of Sciences, Engineering, and Medicine (the Academies) serve the federal government, researchers, practitioners, and the public through thought leadership and authoritative, unbiased technical advice. Congress, federal agencies, and nonprofit or philanthropic organizations seek National Academies' advice and expertise on energy and its environmental, economic, and social consequences, overseen by the Board on Energy and Environmental Systems (BEES). Recent BEES studies have addressed technology and policy for the electric grid (1), decarbonizing the energy system (2), evaluations of the Department of Energy's research activities (3, 4), and assessment of the status of various energy technologies (5–8). To complete its studies, BEES assembles committees of experts with diverse backgrounds who meet, collect information, and come to consensus on a study report with findings and recommendations reflecting the committee's conclusions. Committees operate independently of their sponsoring federal agency or other sponsor, with information gathering open to the public, and committee deliberations confidential. Needs for advice change over time as the energy system and societal priorities evolve. Congress often mandates Academies' studies when it authorizes new or modified action by a federal agency. For example, Congress has requested Academies' advice on technologies for light-duty (passenger car and truck) vehicle fuel efficiency through mandates in 2001 (9) and 2007 (10). These mandates resulted in four consensus reports released in 2002, 2011, 2015, and 2021 (5, 11–13) sponsored by the Department of Transportation's National Highway Traffic Safety Administration (NHTSA). These studies contained findings, recommendations, and detailed analyses that have helped to shape federal vehicle efficiency and greenhouse gas (GHG) emission regulations over the last two decades.


Superparamagnetic MoS2/SiO2/Fe3O4 catalysts that consist of magnetite as the core, silica as the covering layer, and molybdenum sulfide as the top layer were prepared in easy steps. Two different surfactants (anionic and cationic) were used to assist with the synthesis of two of the samples, and one sample was prepared without surfactant. The surfactant was found to have a significant effect on the properties and activity of the final catalysts. Hydrodesulfurization (HDS) tests of the catalysts show higher activity for the cationic‐surfactant‐assisted catalyst. Between the direct desulfurization (DDS) and hydrogenation pathways for the prepared catalysts, the DDS pathway was found to be dominant for the HDS of dibenzothiophene. As a result of the magnetic properties of this catalyst, it can be separated easily from the reaction media by a magnetic field applied externally and reused, which makes it an ideal choice for slurry reactors that process heavy and extra‐heavy crude oil.


The trend towards highly parallel multi-processing is ubiquitous in all modern computer architectures, ranging from handheld devices to large-scale HPC systems; yet many applications are struggling to fully utilise the multiple levels of parallelism exposed in modern high-performance platforms. In order to realise the full potential of recent hardware advances, a mixed-mode between shared-memory programming techniques and inter-node message passing can be adopted which provides high-levels of parallelism with minimal overheads. For scientific applications this entails that not only the simulation code itself, but the whole software stack needs to evolve. In this paper, we evaluate the mixed-mode performance of PETSc, a widely used scientific library for the scalable solution of partial differential equations. We describe the addition of OpenMP threaded functionality to the library, focusing on sparse matrix-vector multiplication. We highlight key challenges in achieving good parallel performance, such as explicit communication overlap using task-based parallelism, and show how to further improve performance by explicitly load balancing threads within MPI processes. Using a set of matrices extracted from Fluidity, a CFD application code which uses the library as its linear solver engine, we then benchmark the parallel performance of mixed-mode PETSc across multiple nodes on several modern HPC architectures. We evaluate the parallel scalability on Uniform Memory Access (UMA) systems, such as the Fujitsu PRIMEHPC FX10 and IBM BlueGene/Q, as well as a Non-Uniform Memory Access (NUMA) Cray XE6 platform. A detailed comparison is performed which highlights the characteristics of each particular architecture, before demonstrating efficient strong scalability of sparse matrix-vector multiplication with significant speedups over the pure-MPI mode.


The purpose of this brief paper is to record a number of observations in connection with varicella. This disease is not of great importance in itself, but it acquires a special prominence through its possible confusion with smallpox. The differential diagnosis of these two affections, based on a study of many cases observed during a recent variolous epidemic, is given at some length. In the presentation of the accompanying data no pretense is made at logical sequence. At the present day it would appear an act of supererogation to devote any time to proving the non-identity of chicken-pox and smallpox. And yet only a quarter of a century ago the relation of these two diseases was the subject of acrimonious controversy. The great Viennese dermatologist, Hebra, a man of large experience in eruptive fevers, loudly proclaimed the unity of these two diseases.


The Stockholmprogramme was recently adopted by the European Council. In a five-year period the focus of EUs work should be in the area of justice and security. Human rights defenders has criticized the European Union for promoting the security of the Union before human rights. The purpose of this paper is to introduce the contradictions in the Stockholmprogramme about the right to seek asylum and why these occur.
By investigating the Stockholmprogramme and following the modern refugee debate the result has shown that the European identity prevent possibilities for refugee protection when universal human rights is put against national interest to defeat terrorism. Myths about "good refugee" and "bad refugee" can explain why the Stockholmprogramme cannot provide shelter for refugees. The argument of this paper is that it´s meaningless to strive towards a vision that do not fully respect the human rights.

Abstract Background: Research results on the efficacy of sunblock sticks in avoiding or reducing Herpes labialis (HL) recurrences are contradictory and has shown mixed results, with some protection reported under experimental conditions that could not be replicated under natural conditions. Objective: The purpose of the present work was to carry out an in vivo test on the effectiveness of a protective lip product in preventing recurrent HL in natural conditions during summer. Methods: An exploratory randomized crossover study was performed on 20 adult volunteers who served as their own controls during the analysis. The study was conducted between May and July 2017 around the summer solstice. During the two-month period, volunteers had to perform normal daily activities and also needed to go to the beach in Sardinia; thirty subjects applying SPF 30 protection and 30 without protection. Results: In individuals with stick protection, the number of HL attacks was significantly reduced. Based on association between different parameters, which emerged from the medical history and the post-test questionnaire, it was found that male individuals over 44 y of age and with Fitzpatrick skin type 2 were the most exposed to recurrence. Conclusion: HL recurrence rate can be reduced by using sunblock stick in summer.


The water-gas shift (WGS) reaction converts CO in the presence of HO into CO and H , which allows controlling the H to CO ratio for the synthesis of NH and CH OH, production of synthetic fuels, etc. [1,2]. Due to reversible and exothermic nature of the WGS reaction (Equation (1)), the reaction is industrially performed in several stages with different catalysts to attain greater CO equilibrium conversions [3,4]. The low-temperature water gas shift (LT-WGS) reaction is performed at ~190–250 °C with copper-zinc-oxide based catalysts and the high-temperature water gas shift (HT-WGS) reaction is performed at ~350–450 °C with iron oxide-based catalysts: making partial or complete solid solution with the bulk Fe-oxide phase and by promoting highly redox Cu -FeO interfacial sites on the catalyst surface. The poorer performance exhibited by Co and Ge promoters is related to the lack of their ability to promote the highly active Cu -FeO interfacial sites along with inability of Co to stabilize the surface area. All the promoters follow a redox type mechanism for the HT-WGS reaction. CO-TPR, CO+H O TPSR and SS-WGS activity experiments were conducted to understand the catalyst structure, nature of the active site, structure-function relationship, and the HT-WGS reaction mechanism. It was found that both Ca and Ni promote the formation of highly active FeO -Cu interfacial areas and exhibit better SS-WGS activity, compared to the 3Cu8CrFe catalyst. The Co and Ge promoters, however, lack the ability to promote the FeO -Cu interface and perform poorly for the HT-WGS reaction. These activity findings are related to the ability of the promoters to form solid solutions with the Fe O support (Cr, Ni and Ca). Promoters that do not stabilize the Fe O surface area (Co), do not dissolve in the Fe O lattice (Ge), are surface enriched and minimize formation of FeO-Cu interfacial sites. This suggests that FeO-Cu interfacial sites are active sites for 3Cu8MFe catalysts. The role of FeO -Cu interfacial sites was further elaborated upon by correlating the redox ability with SS-WGS performance. Consequently, both redox ability and SS-WGS performance follow the same trend: 3Cu8CaFe > 3Cu8NiFe ≥ 3Cu8CrFe > 3Cu8CoFe >> 3Cu8GeFe. This trend reveals that both Ca and Ni can be utilized as substitutes for the toxic Cr promoter in the HT-WGS catalyst. Furthermore, all the catalysts follow the redox-type reaction mechanism for the HT-WGS reaction. For detailed experimental findings, interested readers are redirected to the published article.


We consider a manifold M equipped with 1-forms which satisfy certain contact like properties. We prove a generalization of the classical Darboux theorem for such manifolds.


The article entitled "Historical truth in the images of women in Shakhrizad stories" is scientifically based on the historical authenticity of the stories presented in some stories related to female images. The image of patriotic women in "A Thousand and One Nights" has its roots in ancient times, such as "Tomaris" and "Zarina", which are common to the peoples of the East, including Central Asia

Objective To investigate the expression and clinical significance of p16 in cervical condyloma accuminatum and cervical squamous cell carcinoma.Methods Imunohistochemical staining was performed with s-p method to detect the expression of p16 proteins in the epithelial tissue of 40 cases of cervical condyloma accuminatum and 40 cases of cervical squamous cell carcinoma,10 cases of normal cervix as the controls.Results The positive staining of p16 in cervical squamous cell carcino- ma,cervical condyloma accuminatum and normal cervix was 90%,35% and 30% respectively.The ex- pression of p16 in cervical squamous cell carcinoma was significantly stronger than that in cervical condyloma accuminatum and normal cervical tissue(P0.01).There was no significant difference exis- ting between cervical condyloma accuminatum and normal cervix (P0.05).The expression of p16 was significantly related to lymphatic metastasis(P0.05);however,it had no statistical relation to the clini- cal phases and histopathological stages(P0.05).Conclusion It is possible to predict the canceration of cervical condyloma accuminatum and diagnose it in early stage,by detecting the expression of p16 in tissue of condyloma accuminatum clinically.


Accreditation of cerebrovascular ultrasound laboratories by the Intersocietal Accreditation Commission (IAC) and equivalent organizations is supported by the Joint Commission certification of stroke centers. Limited information exists on the accreditation status and geographic distribution of cerebrovascular testing facilities in the United States. Our study objectives were to identify the proportion of IAC‐accredited outpatient cerebrovascular testing facilities used by Medicare beneficiaries, describe their geographic distribution, and identify variations in cerebrovascular testing procedure types and volumes by accreditation status.


This paper presents an empirical analysis of Italian directed motion verbs and manner of motion verbs; the research is based on a lexical resource of 234 verbs subdivided into six classes. Directed motion verbs are analysed according to their argument structure and to the type of path PP they take: both source and goal PPs, only source PPs or only goal PPs. Furthermore, I have highlighted how the morphological, distributional and semantic properties of these verbs have an impact on their argument structure.Manner of motion verbs are analysed according to their unaccusative/unergative structure and on the semantic components they entail: only Manner or Manner and Direction. Analysis of the data shows that the semantics of both types of motion verbs depends in many cases on the distributional context in which they occur. As a result, it is not always an easy task to generalize the semantic components the verbs lexicalize. The Italian data also show that, contrary to the hypothesis proposed by Rappaport Hovav & Levin (2010) and Levin & Rappaport Hovav (2013) on the opposition between manner and direction, a subset of Italian motion verbs encodes both manner and direction. Moreover, the Italian lexicon shows an abundance of manner of motion verbs that can resort to a satellite-framed strategy, suggesting that the clearcut opposition between satellite-framed and verb-framed languages claimed in Talmy (1985) boils down to a tendency.


It is difficult to organize urban transport in a city center. Existing buildings, narrow streets and operating infrastructure make it difficult to let old-fashion transport means like tram or bus. In the paper, a raised transport consisting of ring monorail and commuter PRT network are analyzed. The proposed solution consists of fast ring railway called "monorail" and PRT (personal rapid transit) network serving as side roads. These two transportation means form a hierarchically layered system. It is shown on an case of an exemplary city that the proposed solution is possible and reasonable. A ridership of the whole system is obtained: for monorail by analytical calculations and for PRT by simulation.


It damages the apple tree, sweet cherry, peach, plum, cherry plum, pear and almond. Hibernates in the egg phase on the bark of shoots and branches, in forks. Hatching of larvae is observed at the end of the blooming of the apple tree. The released larvae feed on budding buds, young leaves. Then go to the shoots, branches. Similar transitions are observed in protononym and deutonymph, which turns into an adult. The development of the tick from larva to adult female is 30 days.


The article presents the developments of systems for storage and display of very fragile textiles at the National Museum of World Cultures, Gothenburg Sweeden, during the last 70 years. It focuses on the work carried out with the collections of Pre-Columbian textiles in the museum's care, including the 97 outstanding Paracas textiles from Peru. The collection has during its time at the museum been housed in three buildings at different times and in varying storage systems, including rolled and flat storage and hanging display as well as display in nitrogen gas atmosphere. The damaging effects that a museum environment can cause textile collections through exposure to light, air, improper storage and display, transportation and handling are presented. The negative impact of these factors on the textile material is revealed, through the change in the collection's condition. This led to the development of a new and purpose built permanent objects storage system at the Museum of World Cultures. A system that has preventive conservation measures inbuilt in its construction with the intention of minimizing future degradation of the collection.


There are at least 125 Galactic pulsar wind nebulae (PWNe) that have been discovered from radio wavelengths to TeV gamma-rays, the majority of which were first identified in radio or X-ray surveys. An increasing number of PWNe are being identified in the TeV band by ground-based air Cherenkov Telescopes such as HESS, MAGIC, and VERITAS such that they constitute the dominant source class of Galactic TeV emitters. Combining available MeV-GeV data with observations in the TeV band is critical for precise characterization of high-energy emission from the relativistic particle population in PWNe, thus revealing the capability to produce a significant fraction of the detected Galactic CR flux. However, MeV-GeV PWN counterparts are still largely lacking even after 12 years of continuous observation of the entire sky. Less than a dozen PWNe are currently identified by the Fermi-LAT in the MeV-GeV band. Most PWNe are located along the Galactic plane embedded within the prominent, diffuse Galactic gamma-ray emission, which makes these sources difficult to disentangle from the bright diffuse background. We present a systematic search for gamma-ray counterparts to known PWNe in the 300MeV - 2TeV energy band using 11.5 years of Fermi-LAT data. For the first part of this search, we target the locations of PWNe previously identified across the electromagnetic spectrum that are not powered by pulsars previously detected by the Fermi-LAT as pulsating gamma-ray signals, which includes 6 Fermi PWNe and 7 Fermi PWN associations. We report the analysis of 58 total regions of interest and provide all firm and tentative detections along with their morphological and spectral characteristics. There are 11 unidentified gamma-ray sources that we classify as firm PWN counterparts, which doubles the PWN population detected by the Fermi-LAT, and 22 gamma-ray sources that are PWN candidates.


The superconformal structure of the (4,0) supergeometry of two-dimensional harmonic superspace is characterized by the super-Beltrami differentials. The BRST algebra including super-Beltrami variables and matter superfields of arbitrary U(1) charges is constructed. The (4,0) locally supersymmetric matter action in the super-Beltrami parametrization is constructed and the super-stress-energy tensors are obtained. Furthermore, the (4,0) superconformal anomaly is given and the super-operator-product expansion of the (4,0) super-stress-energy tensor [ital J]([ital Z]) is derived.


New harpoon finds After the publication in KUML 1971 of the harpoons then known (1) my attention was drawn to a number of other specimens, hitherto unknown and all to be found in private collections.Notable among the new harpoons is the single-rowed specimen fig. 1, which is a casual find from Tudeå, western Zealand. Found in fresh water, it was probably used for catching large freshwater fish like salmon, pike or catfish.Apart from superficial recent damage, the harpoon is entire. The raw material is red deer antler. The surface has been scraped smooth and the base exhibits a row of distinct secondary cuts which are probably due to a change in the method of hafting during the life of the harpoon. The line hole has a biconical section. The overall length is 32.6 cm. The two decorative elements seen on the convex, smooth side in this specimen - fine lines and deeper nicks - are combined and therefore contemporaneous. The patterns consist of lines with short transverse strokes (Clark motif c), bands with transverse hatching (Clark motif f) with small triangular figures which occur here for the first time in the Danish Mesolithic, and large hatched triangles.The decoration is difficult to interpret on account of its condition; it is probably purely geometric, but the possibility that it is a stylized animal or human representation cannot be ruled out. The ornaments on the Tudeå harpoon are, with one exception, well known from previous finds. Corresponding motifs are known from both the Maglemose and Kongemose cultures, especially from the many axes of the latter, for example those from Ølby Lyng (Kemisk Værk) (25), Carstensminde (26) and Værebro Å (28). The Tudeå harpoon should on the basis of its similarity to other well-dated specimens be assigned to the later Kongemose - earliest Ertebølle culture.The disharmony between the patterns and the shape of the harpoon shows that the decoration was probably not made for the harpoon. As several instances are known of broken antler axes having been reused as raw material for harpoons, there is reason to believe that the Tudeå harpoon has been made from a decorated antler axe of the same type as the axe from Værebro, fig. 3. The harpoon was presumably made about the same time as the axe and derives from the same period, in which case it is the oldest antler harpoon known from Denmark.A comparison between the Tudeå harpoon and the later Ertebølle harpoons also shows a number of obvious differences, first and foremost with respect to dimensions, the number of barbs and their shape, the positioning of the line hole and the length of the base. The length of the Tudeå harpoon brings to mind the earlier published unfinished harpoon from the Kongemose settlement, and an unfinished harpoon of the same size is also known from the Carstensminde settlement. These few scattered finds suggest that the single-rowed harpoons underwent a typological development in the course of the Atlantic period from long (30-35 cm) harpoons with numerous short barbs, asymmetrical line hole and long base, to shorter (15-20 cm) harpoons with one or a few, large, sturdy barbs, symmetrical line hole and short base. The material is, however, still too small for definitive conclusions to be drawn.The single-rowed harpoon, fig. 5, is a single find recovered from the stone reef Rønnerne in the western Limfjord (same locality as the harpoon fig. 7). The base and point of this very well preserved specimen have been carefully smoothed. The cylindrical line hole was drilled from the convex face. The overall length is 25 cm.This harpoon does not resemble any of the certain Ertebølle harpoons, but is allied in shape to the previously published harpoon from Præstø By (44), which is also a single find. Presumably these two harpoons represent a special type or variant of harpoons of type A (33).The regular rectangular base with pronounced shoulder is not found in any of the certain Ertebølle harpoons but is known from a Neolithic harpoon from Livø Tap (fig. 8) and in the Swedish Pitted Ware harpoons.The sparse material thus seems to suggest that this variant should be assigned to one of the Neolithic cultures.The harpoon, fig. 4, stems from the same locality as the previous specimen. It is made from a large hollow bone of unidentified species and is broken at the point and base. The line hole was drilled from both sides. The overall length is 8.6 cm.This harpoon is typologically related to Ertebølle harpoons of type A (33), but differs from these in the choice of raw material - bone - which has not been noted hitherto in Ertebølle harpoons. The specimen was recovered from the sea floor with other Ertebølle artefacts, although there is no guarantee of coevality; the harpoon may indeed belong to the Ertebølle culture, but other possibilities should not be ruled out.The specimen illustrated in fig. 8 also derives from the Limfjord (48). It was recovered from the sea floor on Livø Tap, which has already yielded another published harpoon (49). The raw material of this well preserved harpoon is domestic ox (52). The surface has been scraped smooth but exhibits in several places clear traces of rough polishing, which has not been demonstrated before in Danish harpoons. The line hole has a biconical section. The overall length is 18 cm. The raw material, mode of manufacture and shape of this harpoon suggest that it should be assigned to the Neolithic. Morphological similarity to Swedish, Pitted Ware harpoons suggests that it belongs to the Pitted Ware culture whose settlements are found in large areas in the very region where the harpoon was found (51).Finally, the material has been supplemented by the demonstration of a point fragment of a roe deer harpoon (type C) from the Ertebølle settlement of Nivågård in eastern Zealand. This fragment was found in the upper part of the culture layer, which is dated to the Dyrholmen II phase.The new harpoon finds have in several respects furnished us with new knowledge of the chronological and spatial distribution of this artefact group.For the first time a harpoon has been demonstrated which belongs to the later Kongemose or earliest Ertebølle culture. The earlier indications that antler harpoons were part of the Kongemose culture repertoire seem here to be confirmed. This is an entirely new type, clearly different from those known hitherto. At the same time the hitherto youngest dated harpoon from Denmark has been demonstrated. The specimen, which probably belongs to the Pitted Ware culture, differs in shape, raw material and mode of manufacture from those known previously.It is interesting to note that the Limfjord finds, which have now been augmented with finds from the western part, seem to be grouped around Livø Tap and Rønnerne near Lemvig Fjord -both stone reefs which are still known for their many seals. As it is hardly fortuitous that there is a concentration of harpoons there, these banks must have beeen good for seal hunting in antiquity, too.Søren H. Andersen


The paper deals with fundamentals of systems of Boolean functions called multi-output functions (MOFs). A new approach to representing MOFs is introduced based on a Generalized If-Then-Else (GITE) function. It is shown that known operations on MOFs may be expressed by a GITE function. The GITE forms the algebra of MOFs. We use the properties of this algebra to solve an MOF-decomposition problem. The solution provides a compact representation of MOFs.

Abstract A method of backward-pass multiple model adaptive filtering is developed for a stochastic system, in which the a priori information concerning multiple possible initial states and the predictive information concerning a single final state are available. It is shown that a backwards markovian model which incorporates the a priori information can be directly constructed by using the recursion of a backward-pass fixed-interval smoother. The filter based on this new model reduces to a reverse-time realization of the well-known multiple model (or partitioned) adaptive filter. This filter can also be efficiently implemented by a two-filter form, which can process the observations with a single backward-pass Kalman (or information) filter. The problem description was motivated by the need to construct multiple model adaptive fixed-interval smoothers for stochastic systems with unknown parameters.


Collaborative urban design faces three inherent dilemmas of limitations to time and resources, of barriers to language and communication between professionals and stakeholders, and of the reciprocal nature of the relation between influence and understanding. Parametric design tools may address all of these dilemmas, as they provide a fast way to test different design scenarios and make it possible keep designs open while at the same time allowing for a level of detailing which is high enough to facilitate an understanding of the generic qualities of proposed designs. This is particularly relevant in the context of the urban South, which is characterized by high urban growth rates, weak planning systems and modest means. The current state of planning and urban development in Morocco is introduced as a context for discussing collaborative urban design and parametric urban design, and some tentative conclusions are attempted.


Background: MND has been identified as a degenerative axonal brain disease with focus on upper and lower motor neurons. A high amount of neurons have to be affected before clinical symptoms occur. Our hypothesis is that regional spots of subclinical atrophy can be identified with quantitative routine MRI.
Materials/methods: The design of this pilot study is controlled, prospective and blinded. 5 consecutive patients with a proved diagnosis of MND were enrolled. 3 had bulbar symptoms. 27 healthy subjects served as a normative database. The clinical assessment was paralleled with a 3T MRI examination, including a high resolution T1 sequence (MPRAGE). All MRI data were normalized to a stereotactical space followed by a segmentation algorythm and a voxel wise two sample T test checking each patient and the normative database for any volume deviations. The 3D atrophy maps were analysed for each patient and detected for MND specific patterns.
Results: All patients revealed spots of regional White matter (WM) atrophy mainly in the Corpus callosum, cerebellum, pyramidal tract, especially in the brainstem. Single spots of regional brain atrophy were found in the gray matter (GM) of the occipital and temporal lobe and Hippocampus. The brain parenchym fraction, GM and WM volumes were normal.
Conclusions: Our data confirms findings suggesting MND not only restricted to a motor neuron degeneration. Furthermore the presented method is applicable as a surrogate marker for axonal degeneration in MND, supporting diagnosis and monitoring. We suggest to take this quantitative tool into account for treatment studies. Disclosure: Dr. Winkler has nothing to disclose. Dr. Raji has nothing to disclose. Dr. Opfer has nothing to disclose. Dr. Spies has nothing to disclose.


In this chapter, we present a decomposition theory of differential forms on jet prolongations of fibered manifolds; the tools inducing the decompositions are the algebraic trace decomposition theory and the canonical jet projections. Of particular interest is the structure of the contact forms, annihilating integrable sections of the jet prolongations. We also study decompositions of forms defined by fibered homotopy operators and state the corresponding fibered Poincare-Volterra lemma.


An important aspect of research in the remote sensing field is to objectively compare different classifiers. This is the foundation of hundreds of research projects and in this paper we will address some raising concerns when evaluating solutions for classification of data sets with skewed class distributions. The quality of assessment is based on the problem specified by the user and the corresponding hypothesis defined. This hypothesis will determine how two or more classifiers are scored to determine which one is better for a particular application. In this paper we present two experiments that illustrate how, if unaware and misunderstood, statistical measurements can be misleading. One experiment is based on a Synthetic Aperture Radar image with a highly skewed class distribution and the second experiment is based on a Landsat image with a minor skewed distribution. From both experiments it can be seen that ill-defining the problem, can lead to false statements and the reporting of statistically invalid conclusions.


Biofilm are densely packed communities of germ cell (bacterial cells), that grow either on living or inertsurface, surround themselves with secreted polymers, the role of biofilm formation and development bybacteria has been suggested to be an important stage in the pathogenesis of numerous bacterial species.In this study klebsiella pneumoniae has been investigated to form biofilms and its relation to antibioticsresistant. The antibiotics which are used in this study are Ciprofloxacin (CIP) and Cefotaxime (CTX) becausemost of the isolates showed resistance to these antibiotics. The experiment was design to check the causeof UTI in the different types of patient by taking their urine as a specimen sample. Out of 160; 24 samplesshowed Klebsiella pneumoniae, which cause the urinary tract infection. The organisms were identifiedby the DNA isolation and checking with PCR using 16SrRNA. Antibiotic susceptibility for the differentgroups of antibiotic were done by using disk diffusion method against all Klebsiella pneumoniae isolates.Klebsiella pneumoniae are important infectious bacterium and become more dangerous with their capacityof multi-drug resistant. Therefore, there is need to find out alternate therapy to eradicate the infection of thisbacterium by reduce the formation of biofilm which may lead to decrease the antibiotics resistance.


We develop a model of wage determination with private information in a unionized imperfectly competitive industry. Under two different bargaining structures (firm-level vs industry-level), we investigate the effects of the degree of product differentiation and the type of market competition (Bertrand vs Cournot competition) on the negotiated wage and the strike activity. If the wage bargaining takes place at the industry-level, then both the wage outcome and the strike activity do not depend on the degree of product differentiation whatever the type of market competition. However, if the wage bargaining takes place at the firm-level, then wages and strikes are increasing with the degree of product differentiation, and the strike activity is smaller under Bertrand than under Cournot competition.


The reliability of the electrical networks significantly impacts customer as well as energy providers' bottom line. Connectivity between the various sectors of the electrical network has been expressively increased due to the high penetration of the new smart hardware and software tools. Therefore, Prognostics and Health Management (PHM) becoming a critical factor in the efficiency of capital-intensive corporations especially for the energy sector including the electrical power generation. Degradation based analysis is one of the valuable approaches of condition-based algorithms in order to obtain the reliability information especially for the highly reliable systems, critical assets, and recently developed products. The main purpose of the degradation-based models is to predict the future condition of the asset and perform the maintenance in an optimized time window before the actual failure of the system. Failure is said to have occurred as a soft failure event in these types of models. The main purpose of this study is to study the essentials in developing the first hitting time degradation-based models to predict the critical time for initiating the maintenance actions in order to optimize the effectiveness of the PHM leading to enhancing the value of the assets for the distributed electrical systems. The analyses are mostly focused on the critical components of the distributed electrical systems. The latest generations of the degradation models are exploring the potential improvements based on the more available information provided by smart devices to predict the critical failure time. Robust predictive models are beneficial to both energy providers and customers to enhance the overall reliability and risk of the system by initiating the maintenance before the physical failure occurs. In this paper, General Path (GP) and Autoregressive (AR) models as general methodologies for degradation models would be discussed in detail based on the depth of the analyses and available information.


Korea and Japan belong to the cultural sphere of Chinese character which has shown its long and indispensable existence in both countries. However, in the semantic range of Chinese words or their directions, some remarkable differences have arisen in each country. Those differences have been produced by the language policy of each country with the different backgrounds while passing through ages. This paper attempts to illustrate some essential examples of the mistranslation of Chinese words appeared in the Korean translation of Japanese literature. What needs to be emphasized here is that the translators do not have enough knowledge on the peculiar Japanese usage of Chinese words and on the different meaning or semantic range of Chinese words used in each country. This fact causes mistakes on the translation. For analysing the causes which resulted in mistranslation, this paper uses the text "SOREKARA" of Soseki Natsume and two Korean versions of it. This paper also aims at providing certain ideas in theorizing the methodology of education in the field of translating Japanese into Korean.


The nonlinear susceptibility of a melt-cast ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}\mathrm{Ca}{\mathrm{Cu}}_{2}{\mathrm{O}}_{8}$ sample, displaying both the paramagnetic Meissner effect and magnetic aging, has been studied experimentally. The presence of magnetic aging in this sample proves that the spontaneous orbital magnetic moments exhibit correlated and frustrated dynamics at low temperatures. The possible existence of a chiral-glass phase transition was investigated by extracting a quantity corresponding to the order parameter susceptibility of the glass phase. It is shown that the expected divergent behavior of this quantity is hampered by relaxation effects and that the sample is out-of-equilibrium already at temperatures slightly below the superconducting transition temperature $({T}_{c})$. Time dependent magnetization experiments indicate that the magnetic relaxation at temperatures close to but below ${T}_{c}$ is due to isolated orbital magnetic moments, not yet being part of the collective orbital moment state that develops at slightly lower temperatures.


Microphones arrays reduce the effects of reverberation and background noise as compared to a single microphone. The resulting improvement in speech intelligibility in rooms is investigated here, following the approach discussed by Houtgast et al. [Acustica 46, 60–72 (1980)]. Room characteristics (volume, reverberation time), the background noise spectrum, and the source‐receiver separation are used to compute a modulation transfer function. This function is input into the procedure described in IEC standard 60268‐16(2003) to arrive at an objective measure of speech intelligibility, the speech transmission index (STI). Doing this for both omnidirectional and microphone array receivers, the improvement in intelligibility is determined. The signal source has the spectral shape of a human talker, as given in the IEC standard; the background noise spectrum is based on measurements made in a restaurant. The benefit of using microphone arrays is discussed for various conditions.

High levels of alpha-1-fetoprotein are usually associated with nonseminoma carcinoma of the testis or hepatocellular carcinoma of the liver. We describe a male patient with extrahepatic hepatocellular carcinoma who presented with a large retroperitoneal mass and extremely high alpha-1-fetoprotein levels. The importance of taking an adequate biopsy specimen cannot be emphasised enough since both prognosis and treatment are completely different.


This article uses the Advocacy Coalition Framework (ACF) (Sabatier and Jenkins-Smith 1999; Weible and Sabatier 2007) and a refined version of the social learning approach of Peter Hall (1993) to assess and explain policy change in the Common (Agricultural) Policy (CAP) with a special view on Environmental Policy Integration (EPI). Three stages of EPI are discerned that move from central to vertical and later horizontal EPI, complementing an impact model of agriculture and the environment with a public goods model. Reform debates appear as prolonged and iterative battles over the institutionalization of new ideas which are finally incorporated into the existing policy framework. The policy network increasingly reflects cross-policy interdependencies and includes superior authorities, rendering the notion of a policy subsystem problematic. Contrary to the social learning model, the major (although not the most radical) change proponent dominates the policy community while superior authorities tend to intervene on behalf of the status quo. The argument is developed on the base of interviews with policy-makers in Brussels.


The current study aims at shedding light on the challenges that might be confronted while teaching English to students with autism spectrum disorders (ASD) and providing remedial teaching strategies that can facilitate teaching English to these special learners. Helping students to achieve their highest potential requires both an understanding of ASD and its characteristics, and the elements of successful program planning required addressing them. Students with ASD are individuals who each has unique strengths and needs. Thus, via analysing the previous literature about the topic and administering a structured questionnaire to twelve (12) English teachers at the University of El-Oued, Algeria investigating the challenges and the teaching strategies that can be used to remedy these challenges, this study attempts to provide a broad lines for a special English syllabus that best meet the needs of students with ASD.


This paper examines empirically the survival of more than 830 American artists who were sufficiently recognized during their lifetime to have exhibited in one of three highly prestigious international exhibitions of art: the 1900 Paris Exposition; the 1913 Armory Show in New York; and the 1939 World's Fair. In terms of market survival, 54 per cent of these artists sold works at auction in the 1987-1997 time period; 20 artists (2.4 per cent) accounted for 70 per cent of auction sales; and market survival was significantly greater for artists from the Paris and Armory shows than the World's Fair (in which concerns for regional and stylistic diversity played an important role in the selection process). Preferences appear relatively stable because the most highly regarded artists from the three shows tended to do best at auction in the 1987-1997 time period. Finally, there is a strong positive relationship between market and non-market survival (as estimated from data on citations to artists in books and periodicals, representation in museum collections and entries in the Grove Dictionary of Art).


Klauba's bungalow in the North Park section of Chicago is a twenty-five minute ride from O'Hare Airport. George and his wife Judith greet me at the door. They are a well-matched couple, tall, amiable, and responsive. They have been jointly interested in Melville since their marriage at the Seaman's Bethel in New Bedford in 2006. Before lunch, George gave me a tour. We lingered in the living room maybe longer than he planned, for I could not take my eyes off a brand-new painting, Ahab Dismasted (fig. 2). This image was taking George's adventure with the novel in a new direction, although he was not yet sure quite where or why. Ahab is standing full-length, alone, against the dark brown inner wall of the ship. He is tall and gaunt, bending down, about to attach his whalebone leg to the stump of his living leg. The gap between the two leg shapes holds your attention, until your eyes rise. There, around the shoulders, are the transparent


One-dimensional Au rows are produced on the TiO2(110) surface by controlled photon-stimulated desorption followed by Au deposition at 750 K. In the resulting (1 × 2) structure, O vacancies are replaced by Au atoms, as demonstrated by combined laterally resolved x-ray spectroscopy and micro-LEED (low-energy electron diffraction) measurements. The experimental results are confirmed by first-principles calculations, which indicate strong Au–Ti bonding and a very stable configuration of the Au rows. The calculations determine the detailed atomic structure of the Au rows, with an inter-row spacing of 13 Å and an intra-row Au distance of 2.95 Å.


Acanthite (Ag 2 S), Stibnite (Sb 2 S 3 ) and Boumonite (CuPbSbS 3 ) were synthesized by the evacuated silica tube method under dry conditions. Boumonite was synthesized both from its elemental composition and from the component sulfides. All the products were characterized by the optical and XRD methods and were found to be pure, homogeneous and direct semiconductors. Diffuse reflectance studies were undertaken on these synthetic mineral phases. The forbidden energy gap (E g ) was calculated by α 2 vs. hν plots and linear extrapolation to α 2 = zero. E g was also deduced by calculating the Kubelka - Munk remission function, and plotting it against the photon energy. The E g values obtained were: acanthite 0.98, 1.0 eV; stibnite 1.50, 1.55 eV and boumonite 1.15, 1.23 eV. Possible industrial application of these syntheti∼ semiconducting mineral phases are discussed.


Titanium nano-layers were prepared on glass substrates by physical vapor deposition method, under HV conditions, with different deposition angles of 0, 10, 15 and 20 degrees, at room temperature. Thickness of titanium nanolayers was obtained 83.7 nm, by quartz crystal technique. Absorbance, reflectance and transmittance of these layers were measured by spectrophotometer in visible spectral range. The optical parameters were obtained by kramers-kronig method. The aim of this work is to use different deposition angles for titanium nano-layers and investigate the relation between nano structure and optical properties.


In multiple input single output (MISO) systems, two out of N transmit antennas are selected using delayed feedback. Assuming Alamouti transmit diversity and flat Rayleigh fading channel, we derive expressions of symbol error rate (SER) considering two modulation schemes MPSK and MQAM in simple form. Further, we derive expressions of probability of outage for the considered sub-optimum AS scheme. All the expressions are derived as a function of correlation coefficient (ρ), where ρ denotes correlation between perfect channel state information (CSI) and delayed version of it. We discuss some special cases of the considered system and compare with the prevailing systems. Furthermore, it is proved analytically that the diversity order of the considered system reduces to two for ρ ≠ 1 (not selecting antennas using perfect CSI). We also present simulation results and show that the analytical results are closely matching with them.


The multiple-plane and multiple-stage (MPMS) switching fabric has attractive scalability features that make it appealing as an alternative for scalable routers. However, scheduling packets in MPMS fabric is complex. In this paper, a novel scheduling scheme is proposed with bandwidth guarantees for the MPMS fabric. It can deliver 100% throughput under Bernoulli uniform traffic, 92% throughput in the worst case under nonuniform traffic and allocate bandwidth according to reserved bandwidth under overloaded traffic.


— In this study, a procedure to automate the design of metal scrap balers is presented. Balers with different sizes can easily and quickly be designed by the procedure. The solid model of a prototype baler is created in SolidWorks. The frame is considered in this work and it is modeled in SolidWorks as the assembly of parts. Each part is modeled as multibody part modeling by using the graphical user interface (GUI). The details such as holes and welding grooves are not considered in the analysis model. The initial prototype model is designed depending on the experience. After the initial analysis, iterative work is necessary to obtain the final design by making changes in the design. A method is presented for quick and easy iteration work. The method uses the computer program developed in VisualBASIC in this study. The dimensions subject to change for each part is recorded to an Excel file. The program reads the dimensions to be changed and automatically makes the changes in SolidWorks model by using the commands of the application programming interface (API). The procedure is applied to design two models of balers with different technical specifications.


The invention discloses a method for removing methylene blue in waste water by carboxylated rosin-based polymeric microspheres. The method comprises the following steps of preparing carboxylated rosin-based polymeric microspheres by utilizing rosin hydroxyl ethyl methacrylate ester, styrene, acrylic monomer, divinyl benzene, initiator azodiisobutyronitrile and dispersant gelatin, adding the prepared carboxylated rosin-based polymeric microspheres into waste water solution including methylene blue, agitating and vibrating the mixture for certain time, so that the methylene blue in the waste water is removed. The concentration of the methylene blue in the waste water solution is 20-550 mg/l, and when the pH value of the waste water solution is 4-12, the removing effect is the best. According to the method provided by the invention, the used carboxylated rosin-based polymeric microspheres have the advantages that the composition is controllable, the granularity is uniform, the adsorption removal efficiency is high, the biocompatibility is good, and the effects of environmental-friendliness and security are good and the like. The method can be operated simply and fast, is easy to mass promote, and can be used for enlarging the application range of rosin.

This work attempts to investigate the influence of a minimal length scale on the statistical aspects of the paramagnetic system. The angular momentum operator and the magnetostatic field in 3-dimensional space described by the Kempf algebra is studied in the special case of α′ = 2α up to the first order over the deformation parameter α. The modified thermodynamical characteristics of the paramagnetic system such as mean energy, entropy, magnetization are obtained. It is shown that the relative magnetization approximately depends on the deformation parameter and orbital angular momentum. The upper limit of the deformation parameter is estimated.

In this paper, the bioethanol production with the thin stillage recirculation in mashing was investigated. The mashing was performed with recirculation of: 0, 10, 20 and 30 % of the thin stillage. The thin stillage recirculation was repeated six times. In the experiment without the thin stillage, the recirculation bioethanol yield (compared to the theoretical yield) was 97.96 %, which implicates that the experiment conditions were chosen and performed well. With the addition of the thin stillage, the bioethanol yield increased and was above 100 %. Higher bioethanol yield than 100 % can be explained by the fact that the thin stillage contains carbohydrates, amino acids and yeast cells degradation products. The bioethanol yield increased with the increased number of thin stillage recirculation cycles. Dry matter content in fermenting slurry increased with the increased thin stillage quantity and the number of the thin stillage recirculation cycles (8.04 % for the first and 9.40 % for the sixth cycle). Dry matter content in thin stillage increased with the increased thin stillage quantity and the number of thin stillage recirculation cycles. Based on the obtained results it can be concluded that thin stillage recirculation increased the bioethanol yield. The highest bioethanol yields were obtained with recirculation of 10% thin stillage.


Sudden unexpected death in epilepsy (SUDEP) is a tragic and devastating event for which the underlying pathophysiology remains poorly understood; this study investigated whether abnormalities in heart rate variability (HRV) are linked to SUDEP in patients with epilepsy due to mutations in sodium channel (SCN) genes.

In Sweden, about 7000 infants are born preterm every year, before 37 weeks, and they account for 4%‐5% of residents under the age of 18. There is an ongoing debate about how preterm birth affects health outcomes during the early postnatal weeks and in adult life. For example, preterm birth has been associated with a higher incidence of cardiovascular, metabolic and mental health issues in adulthood.1 In this issue of Acta Paediatrica, Forsum et al2 used weight and air‐displacement plethysmography to investigate the fat mass and fat‐free mass of 188 preterm children born at 23.2‐36.9 weeks of gestation, including 73 born very and extremely preterm before week 32. These are called the early preterm group in the paper, and any aged 32 weeks or more are called late preterm. The authors compared them with 253 age‐matched full‐term controls when they reached four years of age. The findings confirmed other pre‐puber‐ tal studies that infants born before 32 weeks tended to weigh less and be shorter than full‐term controls.3‐5 The early preterm girls in the Forsum et al study had a significantly lower body mass index (BMI) than the girls in the full‐term control group, but not the early preterm boys. Both the early preterm girls and boys had less fat mass than the corresponding controls. The early preterm girls also had less fat‐free mass than their full‐term peers. The late preterm girls and boys did not differ from the full‐term controls with regard to fat mass. Gestational age was a weak, but significant, positive predictor of the investigated growth variables at follow‐up in girls, but not in boys.2 One of the strengths of the Forsum et al study, apart from the relatively large cohort, was that it was conducted systematically and methodically, with little variations in age between the preterm and full‐term groups at follow‐up. In air‐displacement plethysmography, body composition is esti‐ mated from density, which is then divided into fat mass and fat‐free mass. Total body mass thus equals fat mass plus fat‐free mass. Fat‐ free mass comprises skeletal muscle, organs, bone and supporting tissues. Height is the most important factor in fat‐free mass. Air‐ displacement plethysmography is considered the method of choice for measuring body composition in children, and it is more readily accessible than dual‐energy X‐ray absorptiometry (DEXA), which is mostly used for measuring bone mineral density. However, DEXA measures bone mineral content directly, which means that it elim‐ inates one of the major sources of fat‐free mass variability in the two‐compartment model. Several studies of pre‐pubertal children have found similar re‐ sults to Forsum et al, as the authors pointed out. Huke et al used impedance analysis to evaluate fat mass in 116 preterm born chil‐ dren when they reached 5‐7 years of age and found that they were shorter, weighed less, had lower BMIs and had less fat mass than full‐ term controls.3 Another study investigated 200 preterm children, including those born very preterm and late preterm, using DEXA. After adjusting for height, the preterm group had less fat mass, but similar fat‐free mass, than the full‐term group. Being female strongly predicted elevated fat mass.4 Gianni et al5 found that preterm born children had lower fat masses, heights and weights at five years of age than full‐term controls. Our smaller study of four‐year‐olds differed to Forsum et al as the preterm and full‐term groups had similar BMIs, weights and ad‐ justed height standard deviation scores at follow‐up.6 After adjust‐ ing for height, the preterm group had a greater fat mass and lower fat‐free mass than the full‐term subjects. All these findings lead us to conclude that preterm subjects have a favourable fat mass body composition during pre‐pubertal years, when they remain thin and short. In 1992, Hales and Barker proposed the thrifty‐phenotype hy‐ pothesis7 for the aetiology of type 2 diabetes and suggested that low‐birthweight infants had impaired beta‐cell growth. As long as the individual remained undernourished, the need for insulin was small. However, if the infant ate too much and experienced rapid catch‐up growth, the reduced beta‐cell function could trigger dia‐ betes. The debate continues whether a low birthweight, per se, or weight gain in infancy can predict a worse metabolic outcome in adulthood. In accordance with this, a study of preterm subjects who experi‐ enced rapid catch‐up growth throughout infancy showed a later risk of increased intra‐abdominal adiposity, and altered, decreased insu‐ lin sensitivity.8 In that study, preterm infants who were born small for gestational age seemed to have the greatest risk. Forsum et al2 found that the early preterm girls had a mean birth‐ weight z‐score of −0.93 ± 1.4. That group probably included infants born appropriate for gestational age and small for gestational age, below the 5th percentile or below—2 standard deviations (SD). At a mean age of 4.4 years, the early preterm girls were relatively lighter and shorter than average, with a mean weight of—1 SD compared to the reference value for Swedish children of the same age. At follow‐ up, some early preterm girls weighed<−2 SD of the reference weight.


Theoretical and numerical analyses of the radiation directivity of a guiding radar system based on leaky coaxial cable (LCC) are presented both for buried and open installations in clutter conditions. The theoretical model of fields generated by a cable buried in a lossy half-space, such as a sub-soil medium, is introduced to describe the working characteristics of such a leaky coaxial cable. A numerical procedure which describe various kinds of LCC installations and can predict the effective characteristics of a radar system based on an LC with required parameters including its directional properties, is proposed to analyze the clutter effects and to optimize the sensitivity of such a radar system both for open and buried installations. The distribution of radiation around the cable is examined numerically by use of the LCC buried at depth d in a sub- soil medium, as well as open installation near different kinds of wall. The radiation pattern of such a radar system across the cable installed at height h above the ground is also investigated.


BALB/c female mice were mated to produce one or more litters by DBA/2, Balb/c, or C3H males. Females nonspecifically parous by males of these last two strains served as controls for the influence of age on decreasing immunological reactivity. At various time intervals, up to 1 year after the birth of their last litter, all females were tested for tolerance of DBA/2 grafts by either one of two methods. Maternal tolerance was detectable in multiparous females 1 year post partum at which time tolerance had decreased to a level of about 43 to 47% of that present in females in the immediate postpartum period. It was theoretically estimated that tolerance persists for about 21 to 23 months after parturition, a time that extends beyond the normal life span.


This study investigated whether the α1‐adrenoceptor responsiveness of the renal vasculature was altered in a metabolic syndrome state due to high‐fructose feeding. Male Sprague‐Dawley rats were fed for 8 weeks with 20% fructose in the drinking water (FFR). They were pentobarbitone anaesthetized and the reductions in renal cortical blood flow to intrarenal administration of noradrenaline, phenylephrine, methoxamine and angiotensin II (Ang II) were determined before and after 5‐methylurapidil, chloroethylclonidine (CEC) or BMY 7378. Data, mean±SEM were subjected to ANOVA with significance at P<0.05. FFR had higher systolic blood pressure, plasma glucose and insulin level as compared to control (FFR vs. control, 123±2 vs. 107±1 mmHg, 6.8±0.3 vs. 5±0.3 mmol/L and 2.8±0.2 vs. 1.9±0.2 ng/ml) respectively. FFR expressed reduced (P<0.05) renal vascular responses to noradrenaline, phenylephrine, methoxamine and Ang II by 36%, 26%, 41% and 56% respectively. The response to Ang II was attenuated by 5‐methylurapidil, CEC and BMY 7378 in the FFR and control, while the adrenergic responses were blunted by 5‐methylurapidil and enhanced by CEC and BMY 7378 in the FFR. These findings suggest that α1A‐adrenoceptor is the functional subtype that mediates renal vasoconstriction response in FFR.


The Phosphoinositide 3-Kinase (PI3K) pathway has been extensively studied in tumors due its roles in promoting cellular growth and proliferation [1]. The most common PI3K mutations are in the PIK3CA gene encoding the p110α catalytic subunit, including the "hotspot" activating mutations E545K and H1047R that can lead to constitutive signaling of the pathway [1]. Consequently, activation of the serine/threonine kinase Akt can promote proliferative and cell growth pathways through regulation of mTOR and other intermediates [1]. In addition to driving tumorigenesis, hotspot PIK3CA mutations have also been shown to drive a wide spectrum of non-malignant over-growth disorders collectively termed the PIK3CA-Related Overgrowth Spectrum [2]. More recently, mutations in PIK3CA have been identified in venous malformations (VMs) [3], the most frequent form of vascular malformations with a frequency of about 1 in 5000 people in the general population [4]. These painful and often disfiguring lesions are characterized by endothelial cell overgrowth, loss of supporting mural cells, and a disorganized extracellular matrix resulting in dilated and distended vessels in a variety of tissues, with common occurrence in the cutaneous layer of the skin [4].


INTRODUCTION Heart failure (HF) is a chronic non-communicable disease whose prevalence in the population gets to be 1-2%. At older ages, mainly between 65 and 67 years, this percentage rises to 23% (ERIKSSON et al, 1987), becoming serious problem in the elderly. According to the World Health Organization (WHO), heart failure (HF) is, among all chronic diseases, the most troubling in the health sector in the world. Although there are great advances in medicine over the past five decades, currently, mortality reaches more than 50% of confirmed cases in five years, after the confirmation of diagnosis (ANDERSON, B.; WAAGSTEIN, F., 1993, HO et al, 1993). Although there is no consensus on the criteria necessary to establish a diagnosis of heart failure, it is evident that this condition can represent a major health problem. It was estimated that the HF reaches nearly 4 million Americans with 400,000 new cases each year (MASSIE, B.M., PACKER, M., 1990). According to DBIC (2012), it was observed growth of the elderly population in Brazil and, therefore, potential growth of at-risk patients or patients with HF. In 2007, cardiovascular disease accounted for the third highest cause of hospitalization in public that HF is the most frequent cause of hospitalization for cardiovascular disease. Educational, therapeutic, pharmacological and non pharmacological measures should be encouraged, since the HF is a crippling disease and decreases the quality of life for the patient undergoing modification in normal activities because of the inability to perform certain everyday tasks resulting from injuries caused by HF symptoms (chest pain or discomfort, dyspnea, orthopnea, palpitations, syncope, fatigue and edema) (HURST, J.W., 2000).

We present ARtLens, an Augmented Reality application for the Microsoft HoloLens, which allows museum visitors to actively interact with and learn about artifacts. We designed ARtLens to enhance learning and engagement with museum collections while keeping the focus on the original artifact. ARtLens provides context for an artifact by supplying audio and visual information, and guides visitors in exploring the original artifact. It also allows users to directly manipulate, using gesture-based interactions, holographic representations of related artifacts next to original artifacts in the gallery. We intend to study the impact of ARtLens on object-based learning and engagement of museum visitors in an African Art gallery.


Abstract Math anxiety impairs mathematical performance even in people who are capable of completing the mathematical operations. Pets have been shown to both reduce stress and improve performance during mathematical tasks, and thus may be used to alleviate math anxiety. We tested the effects of visual pet stimuli on stress and performance during timed sets of high school level math problems. The math problems were presented in sets with either images of pets, images of desks, or color blocks displayed vertically along the left hand side of the page. Participants reported the lowest levels of stress for the math problems presented with the pet images which confirmed our hypothesis that self-reported stress would be lowest for the math set presented with the visual pet stimuli. Although there was no concurrent increase in performance, the data suggest that the presence of a comforting stimulus could be an aid to help students relieve math anxiety. Keywords: pets, stress, math anxiety, mathematical task performance ********** Math anxiety can be described as a negative emotional reaction to math that can lead to impaired performance on mathematical tasks. Brunye et al. (2013) suggested that this impaired performance can be explained by the attentional control theory wherein math anxiety occupies working memory capacity to leave insufficient cognitive resources for mathematical processing. Math anxiety leads to math avoidance both throughout one's academic career and in adult life (Brunye et al., 2013; Legg & Locker, 2009; Lyons & Beilock, 2012). Students with math anxiety tend to avoid STEM classes, and adults with math anxiety tend to avoid dealing with math related problems such as financial issues. Math anxiety seems to be learned (Geist, 2010). Culturally held stereotypes as well as the attitudes towards math held by influential adults all seem to foster math anxiety. Current intervention strategies for math anxiety seek to reduce anxiety by introducing humor during math lessons (Ford et al., 2012), utilizing individualized lesson plans (Jansen et al., 2013), and teaching anxious students how to use mindfulness-based stress reduction breathing strategies (Brunye et al., 2013). Although these inventions have been moderately successful, their implementation may be impractical in large public school settings. Pet stimuli may be a valid source of stress reduction in people with math anxiety. Pets have long been touted as being beneficial to their owners' health and well-being. Mainstream media, including medical advising websites such as WebMD (Fields, 2013), have taken for fact that pet ownership is linked to improved health and mood, a phenomenon labeled as the "pet effect." Still, not all studies confirm this finding. Sraatman, Hanson, Endenburg and Mol (1997) did not find any short term differences in participants' blood pressure as they completed a stressful task in the presence of a dog. Still, as Fields (2013) noted, commonly referenced benefits attributed to pet ownership include improved cardiovascular health and mood. Pet owners tend to have a muted stress response as compared to non-pet owners. Children had lower blood pressure while reading out loud to a dog as compared to reading out loud to an adult (Friedmann, Katcher, Thomas, Lynch, & Messent, 1983). Women performing mental math had reduced stress responses as measured by blood pressure when they performed the math in front of a dog as compared to performing the math in front of their best same-sex friend (Allen, Blascovich, Tomaka, & Kelsey, 1991) or in front of their spouse or significant other (Allen, Blascovich, & Mendes, 2002). In a revolutionary study where pet ownership was randomly assigned amongst a very controlled sample of middle-aged stockbrokers with similar health profiles, stockbrokers in the pet ownership condition had significantly muted stress responses when presented with a stressful task as compared to stockbrokers in the no pet condition (Allen, ShykofF, & Izzo, 2001). …


ion could not be possible in the absence of the abstract idea of value. Production prior to capitalist mode of production is the activity of isolated producers of commodities. These producers will incidentally encounter on the market as commodity-owners in order to exchange what they have produced. Pre-capitalist production is concrete; it is the production of a mere commodity as a useful thing which corresponds to some concrete need. Under the capitalist mode of production, which is the only truly social relations of production, all production is organized toward the abstract social goal of producing value, and more importantly, of surplus-value, which is measurable only by abstract time, that is, it is measurable only by the socially necessary time required to produce a commodity. Value is the mediation that « delays » production under the capitalist mode of production. One can speculate that the emergence of value as a universal abstract social goal that organizes production in its entirety towards unstoppable self-valorization is the mode of existence of the social relations that facilitate conceptualization and conceptual thinking,


The application of secondary rotary grouting construction method in reinforcement treatment of the foundation backfilled with mixed stone is introduced, which solve the piling difficulties in such foundations. Reinforcement treatment not only improves the bearing capacity but reduce uneven settlement of foundation.


The respiratory chain of plant mitochondria differs from that in mammalian mitochondria by containing several rotenone-insensitive NAD(P)H dehydrogenases. Two of these are located on the outer, cytosolic surface of the inner membrane. One is specific for NADH, the other for NADPH. Only the latter is inhibited by diphenyleneiodonium (DPI). Both of these enzymes are normally dependent upon Ca 2+ for activity and this constitutes a potentially important mechanism by which thecell can regulate the oxidation of cytosolic NAD(P)H via the concentration of free Ca 2+ . This and other potential regulatory mechanisms such as the substrate concentration and polyamines are discussed.


There is little literature about the effect of risk management on derivatives application,which leads to misunderstanding of the behavior and function of derivatives application.In this paper,based on a sample of China's listed companies who have used derivatives from 2005 to 2011,the effect of risk management on derivatives application has been analyzed.It is found that the effect is very weak.Therefore,the behavior of using derivatives by China's firms is more like a kind of speculation rather than hedge.


The bunker is a securitized storage space that bodies, objects, and materialized information enter in defense against anticipated threat. The mountain or cliff cave was humanity's prehistoric bunker – a geological gift of sanctuary – where our ancestors lived, stored food, and buried their dead. Bunker development, from excavation and underground construction, co-evolved with agricultural sedentarism to protect grain, living people, and stored riches, with these bunkers always outliving their harboured artifacts, and the people who built them. Conceptualisation of these spaces thus lies at the intersection between the materiality of the bunker and temporality of its contents, though scholarly attention has been drastically weighted toward the former.


The project starts with making an inventory on how EU Member States are complying with the requirements of conducting a feasibility study for alternative energy systems for new buildings and which policy they pursue to actively introduce this requirement. Subsequently, in the seven SENTRO countries (Denmark, France, Lithuania, Poland, Slovenia, Sweden and The Netherlands), an inventory is also made of the building practices as a possible barrier of the implementation of alternative energy systems. After this inventory phase, an approach is developed to ensure that assessment of alternative energy systems will become an integral part in the common planning process of new buildings. Supporting tools of the approach (checklist and a handbook) include technical, financial as well as organisational aspects. Core of the project is a field trial in which the developed approach (including the checklist and handbook) is tested in the seven SENTRO countries. Finally, experiences are disseminated through courses and conferences towards the different target groups (e.g. national and international policy makers and key actors in the national building process).


Description and remarks concerning two species from Saint Paul and Amsterdam Islands. The first record of Ovalipes trimaculatus (de Haan, 1833) from Saint Paul Island means a large eastward extension of the previously known distribution of the species (South America, Tristan da Cunha and South Africa). Some pelagic Grapsidae from Amsterdam Island are regarded as conspecific with the specimens of Pachygrapsus sp. recently described from Tristan da Cunha Islands by Holthuis & Sivertsen, and identified as Planes marinus Rathbun, 1914, a species new to the Indian Ocean. Lepas anatifera anatifera is recorded as epizoic on a pereiopod of this latter brachyuran.


In this talk I will present a novel result concerning the theory of distribution regression (DR). The DR problem addresses regression to vector-valued outputs from probability measures. Many important machine learning and statistical tasks fit into this framework, including multi-instance learning, and point estimation problems without analytical solution. Despite the large number of available heuristics, the inherent two-stage sampled nature of the problem (in practice only samples from sampled distributions are observable) makes the theoretical analysis quite challenging. To the best of our knowledge, the only existing technique with consistency guarantees for DR requires density estimation (which often performs poorly in practice), and the domain of the distributions to be compact Euclidean. I am going to present a simple, analytically computable, kernel ridge regression-based alternative to DR with an exact computational-statistical efficiency tradeoff analysis. The established result shows that the studied estimator is not only consistent (which specifically answers a 17-year-old open question), but it is also able to match the one-stage sampled minimax optimal rate. Moreover, this distribution-regression algorithm performs as well in practice as the state-of-the-art, task-specific solution in an aerosol prediction problem.

We study the spin-glass transition in several Ising models of relevance for quantum annealers. We extract the spin-glass critical temperature by extrapolating the pseudo-critical properties obtained with Replica-Exchange Monte-Carlo for finite-size systems. We find a spin-glass phase for some random lattices (random-regular and small-world graphs) in good agreement with previous results. However, our results for the quasi-two-dimensional graphs implemented in the D-Wave annealers (Chimera, Zephyr, and Pegasus) indicate only a zero-temperature spin-glass state, as their pseudo-critical temperature drifts towards smaller values. This implies that the asymptotic runtime to find the low-energy configuration of those graphs is likely to be polynomial in system size, nevertheless, this scaling may only be reached for very large system sizes -- much larger than existing annealers -- as we observe an abrupt increase in the computational cost of the simulations around the pseudo-critical temperatures. Thus, two-dimensional systems with local crossings can display enough complexity to make unfeasible the search with classical methods of low-energy configurations.


Though there has been systematic research on changes of Yellow River in Zhengzhou area and Taohuayu alluvial fan in the historical period, discussions about the fluvial geomorphological features of Yellow River and the channel evolution in the upper alluvial fan in the lower Yellow River in prehi storic period are little and the related understanding is superficial for lack of ancient text data and relevant researches.In the paper,some opinions are put forward for Zhengzhou district significant to the evaluation of the lower Yellow River and the special fluvial geomorphology of prehistoric Yellow River as well as some problems about channel evaluation associated with the neotectonic moveme nt and the effect of tectonic geomorphology in western Zhengzhou on the evaluati on of rivers and lakes.
