    Objective: To assess educational environment in Aga Khan University Medical College (AKUMC) by Dundee Ready Educational Environmental Measure (DREEM) scale. Methods: A cross-sectional survey of students at the AKUMC with simple random sampling was carried out from June 2014 till March 2015. Responses in five subscales were used to calculate DREEM scores. Results: The average DREEM score was 125.77±16.8 with a reliability of 91.3%. With regards to subscales, on the 12-item students’ perceptions of learning (PoL) subscale, the maximum score was 48; 11 items of students’ perceptions of teachers (PoT) had a maximum score of 44; students’ academic self-perceptions (ASP) identified by 8 items showed maximum score of 32; students’ perceptions of atmosphere (PoA) with 12 items obtained maximum score 48 and students’ social self-perceptions (SSP) subscale of 7 items had a maximum score of 28. Conclusion: Students perceived a positive learning environment at AKUMC Karachi. PMID:27375721

  2. The Role of Aga Khan Rural Support Programme in Rural Development in the Karakorum, Hindu Kush & Himalayan Region: Examples from the Northern Mountainous Belt of Pakistan

    Pakistan is predominantly a mountainous country where rural development activities are characterised by inconsistency, politically motivated short-term projects without proper feedback. Since the inception of the country, the top-down approach has been followed, and the same development plans that were formulated for the plain areas have been extended to the mountains without any modification.In doing so, neither the participation of the local communities was cared for, nor the mountain specificities were considered in the planning process.Moreover, the representation of the local inhabitants was improper and contradictory to the facts. This biased approach has been one of the main causes for the failure of development projects carried out by different agencies of the Government. Contrary to the perception of the state authorities, the mountain communities proved to be more open to accept new approaches and demonstrated the capacity and capability of being a dependable development partner.In this paper, a detailed account of the Aga Khan Rural Support Programme (AKRSP) has been presented to assess and evaluate the approach followed by this non-governmental organisation (NGO), and the response of the local inhabitants as collaborators in the development process. The achievements of the AKRSP from project planning,implementation and monitoring can be adopted as a model for rural development not only in the plains,but also in the mountainous areas of the developing countries in the world.

    Enteric fever remains a major health problem in the developing world, including Pakistan. Poor sanitation and hygienic conditions are the major predisposing factors. Salmonella infection with different strains in the same patient has rarely been reported previously. We are reporting two cases of bacteraemia with simultaneous detection of two strains of Salmonella in a single episode of infection. In both the cases, 2 different serotypes of Salmonella were causing bacteraemia leading to fever. In highly endemic area, one must be aware of mixed Salmonella infections as inappropriate diagnosis of such infections may lead to treatment failure.

    2013-01-01

    If we investigate the different nar-rative images of the historic and heroic personage Genghis Khan , the creation of these different iden-tities show a “unity of personality and commonali-ty” .The narratives of both films , Genghis Khan ( chengji sihan) directed by Zhan Xiangchi in 1986 and The Great Man, Genghis khan ( yidai tiaojiao chengji sihan ) directed by Saifu and Mai Lisi in 1997 show us that in the creation of their subject , there is a common quality in the image of Genghis Khan, and an emphasison the theme of unifica-tion.However , if we do a deeper study , we notice that there are obvious difference in the two films ’ narratives, differences in their characterization of Genghis Khan and in the details .When we look at the identity of the directors -Zhang Xiangchi is a Han Chinese , while Sai Fuso and Mai Lisi are Mongolian-we find that there is more meaningful research space to do a comparative study of the two films.This is obvious if we are analyze how two generations with different ethnic identities , such as Han and Mongolia , portray the film image of Geng-his Khan , a man who holds a supreme position in the heart of Mongolia .We can see how the cultural identity of the film director influences the creation of a film based upon a minority cultural theme . The analysis of such a text not only has a relevance to the creation of films with minority themes , but also serves as an important model for the study of history, imagination, and identity in cultural an-thropology . 1.Differences and Identity Cognition The historical realities of the two films basi-cally come from the menggu mishi ( The Secret History of Mongolia).However, both of them have reconstructed “imagination”, which reflects the self-identity cognition of the Han and Mongolian directors.Genghis Khan directed by Zhan Xiang-chi, is grounded more in historical fact and image-ry style.The important events and many of the de-tails in the film come from menggu mishi.The gaze of

    2015-01-01

    Full Text Available The subject of our study is the policy of the Avar Khans towards Russia in XVIII XIX centuries. Most researchers believe that the Avar Khans State was always interested in close relations with the powerful nation, pursued a policy of deepening relations and, almost always, been loyal to Russia. This can be seen in the period of open confrontation Highlanders during the Caucasian War. Of course, such a policy could not lead to conflicts between the Avar Khan State and its nearest neighbors, causing the latter to exercise intolerance such loyalty to Russia. All of these issues are covered with the involvement of the literary and archival materials. Thus, based on the analysis of sources, the author establishes that the manifestation of the desire of the Avar Khan State, which occupies an isolated position in relation to other feudal lords, the establishment of a strong alliance with Russia is always determined by the desire Khans have Russia as a strong and reliable ally than to amass it in as an enemy. On the basis of archival sources, we can state the fact that Russia, in turn, highly valued the loyalty of Khan's house and noted it all sorts of honors. 

  20. Crowdsourcing the unknown: the satellite search for Genghis Khan.

    Directory of Open Access Journals (Sweden)

    Full Text Available Massively parallel collaboration and emergent knowledge generation is described through a large scale survey for archaeological anomalies within ultra-high resolution earth-sensing satellite imagery. Over 10K online volunteers contributed 30K hours (3.4 years, examined 6,000 km², and generated 2.3 million feature categorizations. Motivated by the search for Genghis Khan's tomb, participants were tasked with finding an archaeological enigma that lacks any historical description of its potential visual appearance. Without a pre-existing reference for validation we turn towards consensus, defined by kernel density estimation, to pool human perception for "out of the ordinary" features across a vast landscape. This consensus served as the training mechanism within a self-evolving feedback loop between a participant and the crowd, essential driving a collective reasoning engine for anomaly detection. The resulting map led a National Geographic expedition to confirm 55 archaeological sites across a vast landscape. A increased ground-truthed accuracy was observed in those participants exposed to the peer feedback loop over those whom worked in isolation, suggesting collective reasoning can emerge within networked groups to outperform the aggregate independent ability of individuals to define the unknown.

It was conducted at the Aga Khan University Hospital, Karachi, and comprised of medical charts and radiographic records of patients visiting between 2010 and 2015. Variables such as implant dimensions, final prosthesis, method of retention, loading protocol and patient factors were analysed. A total of 223 implants (143(64.1%) in maxilla and 80(35.9%) in mandible) were placed in 92 subjects (50(54.3%) males and 42(45.7%) females). All implants were Zimmer tapered screw-vent. Length of 108(48.4%) implants was 11.5mm and diameter of 84(37.7%) implants was 4.7mm. Besides, 6(2.7%) implants failed to osseointegrate, whereas 1(0.4%) implant failed at 12 months of loading. Among the 216(96.9%) successful implants, 140(64.8%) served as bridge abutments, 72(33.3%) were single crown abutments and 4(1.9%) were overdenture abutments. Also, 37(17.1%) implants were immediately loaded. The six-year survival rate of implants was 96.9%.

    Highlights: ► Aga2/+ mice, model for Osteogenesis imperfecta, have type I collagen mutation. ► Aga2/+ mice display both moderate and severe phenotypes lethal 6–11th postnatal. ► Internal hemorrhages studied in Aga2/+ vs. control mice at 6 and 9 days postnatal. ► Anatomical and functional findings in-vivo contrasted to the ex-vivo appearance. -- Abstract: Mutations in type I collagen genes (COL1A1/2) typically lead to Osteogenesis imperfecta, the most common heritable cause of skeletal fractures and bone deformation in humans. Heterozygous Col1a1{sup Aga2/+}, animals with a dominant mutation in the terminal C-propeptide domain of type I collagen develop typical skeletal hallmarks and internal hemorrhages starting from 6 day after birth. The disease progression for Aga2/+ mice, however, is not uniform differing between severe phenotype lethal at the 6–11th day of life, and moderate-to-severe one with survival to adulthood. Herein we investigated whether a new modality that combines X-ray computer tomography with fluorescence tomography in one hybrid system can be employed to study internal bleedings in relation to bone fractures and obtain insights into disease progression. The disease phenotype was characterized on Aga2/+ vs. wild type mice between 6 and 9 days postnatal. Anatomical and functional findings obtained in-vivo were contrasted to the ex-vivo appearance of the same tissues under cryo-slicing.

    Analysis of DNA from human archaeological remains is a powerful tool for reconstructing ancient events in human history. To help understand the origin of the inhabitants of Kublai Khan's Upper Capital in Inner Mongolia, we analyzed mitochondrial DNA (mtDNA) polymorphisms in 21 ancient individuals buried in the Zhenzishan cemetery of the Upper Capital. MtDNA coding and noncoding region polymorphisms identified in the ancient individuals were characteristic of the Asian mtDNA haplogroups A, B, N9a, C, D, Z, M7b, and M. Phylogenetic analysis of the ancient mtDNA sequences, and comparison with extant reference populations, revealed that the maternal lineages of the population buried in the Zhenzishan cemetery are of Asian origin and typical of present-day Han Chinese, despite the presence of typical European morphological features in several of the skeletons.

    In Escherichia coli the rare codons AGG, AGA and CGA are reported to have a detrimental effect on protein synthesis, especially during the expression of heterologous proteins. In the present work, we have studied the impact of successive clusters of these rare codons on the accuracy of mRNA translation in E. coli. For this purpose, we have analyzed the expression of an mRNA which contains in its 3' region a triplet and a tandem of AGA codons. This mRNA is derived from the human hepatitis B virus (HBV) preC gene. Both in eukaryotic cells and in eukaryotic cell-free translation system, this mRNA, directs the synthesis of a single 25 kDa protein. However, in a conventional E. coli strain BL 21 (DE3), transformed with a plasmid expressing this protein the synthesis of four polypeptides ranging from 30 to 21.5 kDa can be observed. Using different approaches, notably expression of i) precore mutated proteins or ii) chimeric proteins containing HA- and Myc-tags downstream of the AGA clusters (respectively in the -1 or +1 frame), we have found that when the ribosome encounters the AGA clusters, it can then resume the translation in both +1 and -1 frames. This result is in agreement with the model proposed recently by Baranov et al. (Baranov, P.V., Gesteland, R.F., Atkins, J.F., 2004. P-site tRNA is a crucial initiator of ribosomal frameshifting. RNA 10, 221-230), thus confirming that AGA/AGG codons can serve as sites for -1 frameshifting events. Only +1 frameshifting was suggested previously to occur at the AGA/AGG clusters.

    On the plant surface the dimorphic fungus Ustilago maydis switches from budding to hyphal growth and differentiates appressoria. To get more insight into these highly regulated processes we report on the role of a conserved Ser/Thr kinase of the AGC kinase family, Aga1. U. maydis Aga1 could functionally replace Ypk1p in Saccharomyces cerevisiae. aga1 deletion mutants were affected in growth, cell wall integrity, mating as well as the ability to form appressoria and showed defects in actin organization and actin-dependent endocytosis. With respect to appressorium formation and endocytosis, the aga1 deletion phenotype could be mimicked by inhibiting the formation of actin filaments with Latrunculin A. These data suggest a critical role of Aga1 in F-actin organization during the morphological changes accompanying the development of appressoria.

    Context: Mathematical optimization can be used as a computational tool to obtain the optimal solution to a given problem in a systematic and efficient way. For example, in twice-differentiable functions and problems with no constraints, the optimization consists of finding the points where the gradient of the objective function is zero and using the Hessian matrix to classify the type of each point. Sometimes, however it is impossible to compute these derivatives and other type of techniques must be employed such as the steepest descent/ascent method and more sophisticated methods such as those based on the evolutionary algorithms. Aims: We present a simple algorithm based on the idea of genetic algorithms (GA) for optimization. We refer to this algorithm as AGA (asexual genetic algorithm) and apply it to two kinds of problems: the maximization of a function where classical methods fail and model fitting in astronomy. For the latter case, we minimize the chi-square function to estimate the parameters in two examples: the orbits of exoplanets by taking a set of radial velocity data, and the spectral energy distribution (SED) observed towards a YSO (Young Stellar Object). Methods: The algorithm AGA may also be called genetic, although it differs from standard genetic algorithms in two main aspects: a) the initial population is not encoded; and b) the new generations are constructed by asexual reproduction. Results: Applying our algorithm in optimizing some complicated functions, we find the global maxima within a few iterations. For model fitting to the orbits of exoplanets and the SED of a YSO, we estimate the parameters and their associated errors.

    Members of the Mongol imperial family (designated the Golden family) are buried in a secret necropolis; therefore, none of their burial grounds have been found. In 2004, we first discovered 5 graves belonging to the Golden family in Tavan Tolgoi, Eastern Mongolia. To define the genealogy of the 5 bodies and the kinship among them, SNP and/or STR profiles of mitochondria, autosomes, and Y chromosomes were analyzed. Four of the 5 bodies were determined to carry the mitochondrial DNA haplogroup D4, while the fifth carried haplogroup CZ, indicating that this individual had no kinship with the others. Meanwhile, Y-SNP and Y-STR profiles indicate that the males examined belonged to the R1b-M343 haplogroup. Thus, their East Asian D4 or CZ matrilineal and West Eurasian R1b-M343 patrilineal origins reveal genealogical admixture between Caucasoid and Mongoloid ethnic groups, despite a Mongoloid physical appearance. In addition, Y chromosomal and autosomal STR profiles revealed that the four D4-carrying bodies bore the relationship of either mother and three sons or four full siblings with almost the same probability. Moreover, the geographical distribution of R1b-M343-carrying modern-day individuals demonstrates that descendants of Tavan Tolgoi bodies today live mainly in Western Eurasia, with a high frequency in the territories of the past Mongol khanates. Here, we propose that Genghis Khan and his family carried Y-haplogroup R1b-M343, which is prevalent in West Eurasia, rather than the Y-haplogroup C3c-M48, which is prevalent in Asia and which is widely accepted to be present in the family members of Genghis Khan. Additionally, Tavan Tolgoi bodies may have been the product of marriages between the lineage of Genghis Khan’s Borjigin clan and the lineage of either the Ongud or Hongirad clans, indicating that these individuals were members of Genghis Khan’s immediate family or his close relatives.

    Interest in agar or agarose-based pharmaceutical products has driven the search for potent agarolytic enzymes. An extracellular β-agarase (AgaA7) recently isolated from Pseudoalteromonas hodoensis sp. nov was expressed in Bacillus subtilis, which was chosen due to its capability to overproduce and secrete functional enzymes. Phenotypic analysis showed that the engineered B. subtilis secreted a functional AgaA7 when fused with the aprE signal peptide (SP) at the amino-terminus. The maximum agarolytic activity was observed during the late logarithmic phase. To further improve the secretion of AgaA7, an expression library of AgaA7 fused to different naturally occurring B. subtilis SPs was created. The amount of AgaA7 secreted by the clones was compared through activity assay, immuno-blot, and purification via affinity chromatography. Although the aprE SP can readily facilitate the secretion of AgaA7, other SPs such as yqgA, pel, and lipA were relatively more efficient. Among these SPs, lipA was the most efficient in improving the secretion of AgaA7.The use of B. subtilis as host for the expression and secretion of agarolytic and other hydrolytic enzymes can be a useful tool in the field of white biotechnology.

  1. Google, Mathletics and Khan Academy: students' self-initiated use of online mathematical resources

    Today's students increasingly engage in online environments, with ready access to digital resources and mobile technologies. While much of this activity is socially motivated, the internet is also a source of knowledge for students and frequently accessed for school assignments, projects and assessment purposes. As mathematics continues to be an area in which many students experience difficulties, it is not surprising that a recent Google search produced 57,600,000 results for `help with mathematics'. Current research, however, is limited in terms of documenting students' use of such resources, particularly when they are self-initiated and often accessed in an out of classroom environment. This paper reports on a study that investigated the use of mathematical online resources accessed by students in Grades 5-9, with a particular focus on evaluating the effectiveness of Khan Academy, an online tutorial site. Data collected through surveys and interviews showed that while students did access online sites, particularly in the later years of schooling, they varied in both their reasons for doing so and their perceptions of how useful these sites were. The findings add to the limited research in this area and have practical implications for students and teachers, including the potential to challenge the traditional role of the teacher.

    A novel β-agarase AgaJ11 belonging to the glycoside hydrolase (GH) 16 family was identified from an agar-degrading bacterium Gayadomonas joobiniege G7. AgaJ11 was composed of 317 amino acids (35 kDa), including a 26-amino acid signal peptide, and had the highest similarity (44 % identity) to a putative β-agarase from an agarolytic marine bacterium Agarivorans albus MKT 106. The agarase activity of purified AgaJ11 was confirmed by zymogram analysis. The optimum pH and temperature for AgaJ11 activity were determined to be 4.5 and 40 °C, respectively. Notably, AgaJ11 is an acidic β-agarase that was active only at a narrow pH range from 4 to 5, and less than 30 % of its enzymatic activity was retained at other pH conditions. The K m and V max of AgaJ11 for agarose were 21.42 mg/ml and 25 U/mg, respectively. AgaJ11 did not require metal ions for its activity, but severe inhibition by several metal ions was observed. Thin layer chromatography and agarose-liquefying analyses revealed that AgaJ11 is an endo-type β-agarase that hydrolyzes agarose into neoagarohexaose, neoagarotetraose, and neoagarobiose. Therefore, this study shows that AgaJ11 from G. joobiniege G7 is a novel GH16 β-agarase with an acidic enzymatic feature that may be useful for industrial applications.

    The Kenema Government Hospital Lassa Fever Ward in Sierra Leone, directed since 2005 by Dr. Sheikh Humarr Khan, is the only medical unit in the world devoted exclusively to patient care and research of a viral hemorrhagic fever. When Ebola virus disease unexpectedly appeared in West Africa in late 2013 and eventually spread to Kenema, Khan and his fellow healthcare workers remained at their posts, providing care to patients with this devastating illness. Khan and the chief nurse, Mbalu Fonnie, became infected and died at the end of July, a fate that they have sadly shared with more than ten other healthcare workers in Kenema and hundreds across the region. This article pays tribute to Sheik Humarr Khan, Mbalu Fonnie and all the healthcare workers who have acquired Ebola virus disease while fighting the epidemic in West Africa. Besides the emotional losses, the death of so many skilled and experienced healthcare workers will severely impair health care and research in affected regions, which can only be restored through dedicated, long-term programs.

    Rice production in Pakistan is constraint by many factors pertaining to prevalent planting techniques. A research on the feasibility of new planting techniques (direct seeding on flat, transplanting on flat, direct seeding on ridges, transplanting on ridges and parachute planting) in transplanted and direct wet-seeded rice was undertaken at Dera Ismail Khan region of Pakistan's North West Frontier Province during 2002 and 2003. Among the planting techniques, the best performance for the yield formation and economic evaluation was noted for transplanting on flat during both years. Chinese parachute planting technology also showed very promising results in most of the parameters. Direct seeding on ridges could not excel transplanting on flat and parachute planting during both cropping seasons. The findings concluded the feasibility of parachute planting technology along with traditional rice transplanting on flat over all other planting techniques being practiced in the area.

    Indoor radon and its decay products are considered to be the second leading cause of lung cancer after cigarette smoking. This is why extensive radon surveys have been carried out in many countries of the world, including Pakistan. In this context, 25 spots were selected at workplaces in the vicinity of the uranium mining site in Dera Ghazi Khan District for indoor radon measurement. For this purpose, CR-39 based radon detectors were installed at head height and were exposed to indoor radon for 60 days. After retrieval, these detectors were etched in a 6 M solution of NaOH at the temperature of 80 °C for 16 h in order to make the alpha particle tracks visible. The observed track densities were related to the indoor radon concentration using a calibration factor of 2.7 tracks cm(-2) h(-1)/kBq m(-3). The measured indoor radon concentration ranged from ∼386 ±161 to 3028 ± 57 Bq m(-3) with an average value of 1508 ± 81 Bq m(-3) in the studied areas of Dera Ghazi Khan District. The mean annual effective dose ranged from 2.22 ± 0.93 to 17.44 ± 0.33 mSv yr(-1), with an average of 8.68 ± 0.47 mSv yr(-1). The effect of the seasonal correction factor (SCF) on the annual average radon concentration has also been considered. Results of the current study show that, for the majority of the workplaces studied, indoor radon levels exceed the action levels proposed by many world organisations.

    Gayadomonas joobiniege G7 is an agar-degrading marine bacterium belonging to a novel genus. Genomic sequencing of G. joobiniege revealed that AgaJ9 (formerly YjdB) belonging to the glycoside hydrolase (GH) 39 family. It showed the highest similarity (47% identity) to a putative β-agarase from Catenovulum agarivorans DS-2, an agar-degrading marine bacterium sharing the highest similarity in the nucleotide sequence of 16s rRNA gene with G. joobiniege G7. The agaJ9 gene encodes a protein (134 kDa) of 1205 amino acids, including a 23-amino acid signal peptide. The agarase activity of purified AgaJ9 was confirmed by zymogram analysis. The optimum pH and temperature for AgaJ9 activity were determined as 5 and 25 °C, respectively. Notably, AgaJ9 is a cold-adapted β-agarase retaining more than 80% of its activity even at a temperature of 5 °C. In addition, gel filtration chromatography revealed that AgaJ9 exists as two forms, dimer and monomer. Although the two forms had similar enzymatic properties, their kinetic parameters were different. The K m and V max of dimeric AgaJ9 for agarose was 0.68 mg/ml (5.7 × 10(-6) M) and 17.2 U/mg, respectively, whereas the monomeric form had a K m of 1.43 mg/ml (1.2 × 10(-5) M) and V max of 10.7 U/mg. Thin-layer chromatography and agarose-liquefying analyses revealed that AgaJ9 is an endo-type β-agarase that hydrolyzes agarose into neoagarotetraose and neoagarobiose. This study is the first report of a GH39 β-agarase with a cold-adapted enzymatic feature, a unique attribute, which may be useful for industrial applications.

  13. Isolation, characterization, and localization of AgaSGNH cDNA: a new SGNH-motif plant hydrolase specific to Agave americana L. leaf epidermis.

    GDSL and SGNH hydrolases are lipases involved in a wide range of functions, behaving in many cases as bifunctional enzymes. In this work, the isolation and characterization of AgaSGNH, a cDNA encoding a member of the SGNH-hydrolase superfamily from young leaf epidermis of the monocot Agave americana L., is reported. The protein possesses a typical signal peptide at its N-terminus that allows its secretion to the epidermis cell wall, as verified by immunolocalization experiments. In addition, the AgaSGNH sequence contains a His-Leu-Gly-Ala-Glu (HLGAE) motif which is similar to that observed in other plant acyltransferases. Expression levels by northern blot and in situ localization of the corresponding mRNA, as well as the immunolocalization of the protein in Agave young leaves indicate that the protein is specifically present in the epidermal cells. The detailed study performed in different parts of the Agave leaf confirms two aspects: first, the expression of AgaSGNH is limited to the epidermis, and second, the maximum mRNA levels are found in the epidermis of the youngest zones of the leaf which are especially active in cutin biosynthesis. These levels dramatically decrease in the oldest zone of the leaf, where the presence of AgaSGNH mRNA is undetectable, and the biosynthesis of different cuticle components is severely reduced. These data could be compatible with the hypothesis that AgaSGNH could carry out both the hydrolysis and the transfer, from an activated acyl-CoA to a crescent cutin in Agave americana leaves and, therefore, be involved in the still unknown mechanism of plant cutin biosynthesis.

    Although ghrelin in cord blood has been associated to birth weight, its role in fetal and postnatal growth has not been elucidated. The aim of this study was to analyze total ghrelin, acyl ghrelin (AG), and des-acyl ghrelin (DAG) in cord blood of newborns with idiopathic birth weight alterations, and to evaluate protein expression of placental GHS-R1, in order to investigate their correlation with birth weight and placental weight. We performed a cross-sectional comparative study in umbilical cord blood and placentas from healthy mothers of SGA, AGA, and LGA (small, adequate and large for gestational age) term newborns (n = 20 per group). Cord blood total ghrelin, AG, and DAG were measured by ELISA, and placental GHS-R1 expression was evaluated by Western blot. Cord blood DAG was higher in SGA compared to AGA newborns (902.1 ± 109.1 and 597.4 ± 58.2 pg/ml, respectively, p = 0.01) while LGA and AGA showed similar values (627.2 ± 76.4 pg/ml for LGA, p = 0.80). DAG negatively correlated with birthweight (r = -0.31, p = 0.02) and placental weight (r = -0.33, p = 0.02). No differences in AG or total ghrelin were found. GHS-R1 protein in placenta was not differentially expressed among SGA, AGA, and LGA. Our results suggest a role of DAG in intrauterine growth. Further studies are needed in order to elucidate the mechanisms by which DAG participates in fetal growth.

    We studied both colloform-banded macro- and micro-textures as well as the composition of electrum from the epithermal Khan Krum (or Ada Tepe) gold deposit, Bulgaria (5 Mt at 5.1 g/t Au + 2.7 g/t Ag) using optical and electron scanning microscopy, vibration spectroscopy, electron micro-probe analysis, and LA-ICP-MS. The individual textural bands differ in grain size, porosity, quartz-to-adularia ratio, and abundance of electrum, pyrite, and scattered dusty opaque micro-inclusions. The individual macro-bands have formed successively via intermittent fault dilation from episodic hydrothermal pulses, as a result of regional extension and most likely originated from colloidal solutions formed by vigorous boiling during rapid pressure drop and supersaturation with respect to amorphous silica in a closed or quasi-closed hydrothermal system. Electrum is highly concentrated in the finest quartz-adularia colloform micro-bands, which fill joints with widths up to 1-2 mm. We presume that the joints have filled in with more concentrated colloidal solutions than those in the macro-bands, most likely due to extreme boiling of fluids in open or quasi-open hydrothermal system. Electrum in the micro-bands forms transverse dendrite- and chain-like aggregates as well as oval clots along the banding, all of globular morphology. We explain these locations of electrum with reorientation of aggregated electrum globules during plastic deformation of a mixed electrum-silicate gel and in result from the consequent crystallization of silicates. At the same time, electrum is not present in pores and cracks of syneresis, which indicates that it had not been a soluble phase at the time of syneresis, rather colloidal particles. Electrum also forms dense sprinkles of globular morphology deposited in open space on the surfaces of some quartz-adularia bands, due to a condensation of gaseous phase, separated during the boiling of fluids. We found that the electrum-rich quartz-adularia micro

    Full Text Available The artesian aquifers provide economical and sustainable source of groundwater for irrigation and domestic use. GIS (Geographic Information System was used for development and integration of spatial databases, analysis and visualization of spatial data in two- and three-dimensional views. The aquifer system of Daraban Rod-Kohi area of DI Khan was analyzed to identify potential artesian aquifers using geological sections of the observation wells representing detail of subsurface lithology and strata encountered. According to an estimate, about 1,700 million m3 of extractable volume of groundwater exists in this part of rod-kohi area. Different profile sections were drawn to analyze the subsurface condition of the study area using Rockworks GIS-based software. The geo-processing technique of horizontal litho-blending was utilized for lithological modeling. Based on stratigraphic information of the area, three distinct aquifers were identified down to a depth of about 200 meters among which two are semi-confined to confined having prospects of artesian water. The 2D and 3D analysis show that characteristics of the confined aquifers vary spatially with the subsurface lithology and structural setup of the area. The depth range of confined layer-1 is found between 118 and 133 meters while of confined layer-2 between 182 and 195 meters. The output data indicated a close agreement with the observed data of the artesian wells. The study results can provide base for detail investigation of artesian resource and selection of potential sites for installation of artesian wells in the target area.

    Full Text Available Groundwater is considered to be the second largest contributor to the indoor radon concentration after soil. Therefore, measurement of waterborne radon has remained a point of interest for many researchers. The main objective of this study is to study waterborne radon activity in the city of Dera Ismail Khan. In this context, water samples were collected from different locations of the city and waterborne radon was measured using a pylon vacuum water degassing system and CR-39 based radon detectors. The pylon system measured waterborne radon activities in samples of hand pumps and motor driven pumps varying from 0.015 to 0.066 Bq/L and 0.021 to 0.145 Bq/L with average values of 0.041 ± 0.015 Bq/L and 0.076 ± 0.024 Bq/L, respectively. Whereas CR-39 based measured values ranged from 0.042 to 0.125 Bq/L and 0.075 to 0.158 Bq/L with average values of 0.081 ± 0.021 Bq/L and 0.120 ± 0.020 Bq/L, respectively. The estimated average annual effective dose due to ingestion of radon from drinking water using pylon and CR-39 based radon detectors for hand and motor pump samples was found to be 1.055×10-4 mSv and 1.947×10-4 mSv, and 2.067×10-4 mSv and 3.058×10-4 mSv, respectively. The waterborne radon concentrations and as a result the annual effective dose expected to be received from it are within the recommended safe limits.

    The main carbohydrate of red macroalgae is agarose, a heterogeneous polysaccharide composed of D-galactose and 3,6-anhydro-L-galactose. When saccharifying agarose by enzymes, the unique physical properties of agarose, namely the sol-gel transition and the near-insolubility of agarose in water, limit the accessibility of agarose to the enzymes. Due to the lower accessibility of agarose to enzymes in the gel state than to the sol state, it is important to prevent the sol-gel transition by performing the enzymatic liquefaction of agarose at a temperature higher than the sol-gel transition temperature of agarose. In this study, a thermostable endo-type β-agarase, Aga16B, originating from Saccharophagus degradans 2-40(T), was characterized and introduced in the liquefaction process. Aga16B was thermostable up to 50 °C and depolymerized agarose mainly into neoagarooligosaccharides with degrees of polymerization 4 and 6. Aga16B was applied to enzymatic liquefaction of agarose at 45 °C, which was above the sol-gel transition temperature of 1 % (w/v) agarose (∼35 °C) when cooling agarose. This is the first systematic demonstration of enzymatic liquefaction of agarose, enabled by determining the sol-gel temperature of agarose under specific conditions and by characterizing the thermostability of an endo-type β-agarase.

    Hepatocytes were isolated from full-term, SGA and AGA piglets at 6 or 48 hours postpartum and were incubated with 1 mM (1-{sup 14}C)-octanoate (C8), -nonanoate (C9) or-oleate (C18:1). The cells oxidized (natom 1-C/(h 10{sup 6} cells)) C9 to Co{sub 2} (12.5) and acid soluble products (28.9) faster than C8 (10.9, 20.6, respectively), and both were oxidized faster than C18:1 (3.9, 9.9) regardless of the piglet age or weight. Oleate accumulated in lipid products 8-fold faster than C8 and C9. No differences between cells from SGA and AGA piglets were detected. Recovery of 1-C in CO{sub 2} was 48% higher in incubations with cells from 48 hours old than from 6 hour old piglets. This increase was attributable to a 70% higher oxygen consumption by 48 hour old cells. Theoretical oxygen consumption rates were computed from the fatty acid flux data and compared to measured oxygen consumption. hepatocytes from SGA and AGA piglets were equally capable of satisfying more that 57% of their energy needs from fatty acid oxidation. The oxygen consumption attributable to C9 metabolism was 30% higher than observed for C8 and C18:1. All fatty acids apparently spared endogenous fuels to a greater degree in 6 hour than in 48 hour piglets.

    Dera Ismail (D.I.) Khan District contains an area of 3,450 square miles between the right bank of the Indus River and the Sulaiman Range in westcentral West Pakistan. Agriculture is the principal source of income in the District, but only a small part of the arable land is fully utilized. The region is semiarid and has an average annual rainfall of about 9 inches and a potential evapotranspirational rate of eight to nine times the annual rainfall. Thus, rainfall alone is not adequate for high-intensity cropping. Irrigation is practiced near the Indus River; the Paharpur Canal is used, as well as the traditional inundation method. Elsewhere in the District, adequate water is supplied to local areas by karezes, perennial streams from the mountains, and some recently installed tubewells (see 'Glossary'). Further development of ground-water supplies would permit a more effective utilization of most of the presently tilled land and would allow additional land to be farmed. D.I. Khan District is primarily an alluvial plain that slopes from the mountain ranges in the northern and western parts of the District toward the Indus River. Rocks in the bordering mountains are of Paleozoic to early or middle Pleistocene age. The unconsolidated rocks of the plain, of middle (?) Pleistocene to Holocene (Recent) age, consist of piedmont deposits derived from the hills to the north and west and of alluvium laid down by the Indus River. These deposits interfinger in a transitional zone about 8 to 12 miles west of the river. Lithologic and structural features indicate that the unconsolidated rocks possibly may be divided into broad units. The investigations in D.I. Khan District have revealed two main areas of potential ground-water development based on considerations of both permeability and chemical quality of the ground water: 1. A belt about 10 miles wide parallels the Indus River from the Khisor Range southward to the area immediately south of D.I. Khan town. In this belt, the

    Full Text Available Supraglacial lakes are widely distributed on glaciers in the Tomur-Khan Tengri Tianshan Mountains, Central Asia. The existence and development of supraglacial lakes play an important role in the ice melting processes and also in the storage and release of glacial melt water. Here we mapped the supraglacial lakes of eight typical debris-covered dendritic-type glaciers around the Tomur-Khan Tengri peaks based on 9 Landsat TM/ETM+ images acquired in the summers of 1990 until 2011. With a lower area limit of 3600 m2 for a conservative identification of glacial lakes, we mapped 775 supraglacial lakes and 38 marginal glacial lakes in total. Our results indicate that supraglacial lakes (area > 3600 m2 in the study region never develop beyond an elevation of about 3850 m a.s.l., 800 m lower than the maximum upper boundary of debris cover (4650 m a.s.l.. The area-elevation distribution shows that lakes are predominantly occured close to the altitude of 3250 m a.s.l., where the clean ice simultaneously disappears. The majority of the supraglacial lakes are found on the Tomur Glacier and the South Inylchek Glacier, two strongly debris-covered dendritic-type glaciers in the region. As for the multi-year variation of lake area, the summer total and mean areas of supraglacial lakes show some variability from 1990 and 2005 but increased noticeably between 2005 and 2011. The mean area of the mapped lakes reached a maximum in 2010. We found that the area of supraglacial lakes is positively correlated to the total precipitation in summer (July to September but negatively correlated to the mean spring air temperature (April to June. Pre-summer air temperature fluctuations likely have a stronger impact on the different evolution processes of glacial drainage, evolving from unconnected to connected systems, which may lead to the drainage of larger supraglacial lakes and results in shrinkage of the total and mean lake area during the summer.

    Studies were initiated for two consecutive years to find out the effect of time of transplanting and seedlings hill-1 on the productivity of rice in Dera Ismail Khan district of North West Frontier Province (NWFP), Pakistan. The experiment was laid out in a randomized complete block design with split plot arrangements. Main plots consisted of four transplanting dates viz. 20th and 27th of June and 4th and 1 lth of July while sub-plots contained 1, 2, 3 or 4 seedlings hill-1. Among transplanting dates, June 20th planted crop gave highest paddy yield and net return with 1 seedling hill-1. It explains that the use of more seedlings hill-1 not only adds to cost but is also a mere wastage of natural resources. Based on research findings, we conclude that the use of 1 seedling hill-1 is most appropriate for timely sowing otherwise 4 seedlings hill-1 should be used to compensate for the yield gap in late transplanted rice.

    Full Text Available This study has been conducted on the path reports of diagnostic curettage carried out in Mirza koochek-khan hospital during the 6 months of the year 1989 (April to September. The reports examined have been further classified into incompelete abortion, diagnostic currettage and others. A total number of 645 women have had D&C according to the above criteria. In this period of time, incomplete abortion had the highest rate (34% of all D&C's, of which 62.5% were under 20 years of age and 22.6% were primigravida. The ratio of total abortion to the number of deliveries was 9.8% and post-delivery retention of placenta constituted 4.8% of all D&C's, with the highest rate amongst the age group of 15-19 years old, who mostly had home deliveries. The incidence of hydatidiform mole was 3.07 per 1000 deliveries, out of this number, the highest rate (50% belonged to the age group of 20-24 years old. The above incidence is 6.4 times more than the U.S. incidence and 0.9 times less than the incidence reported in other Asian countries (6, 8, 10. Knowing the complication of unplanned abortion such as perforation of the uterus, infection, hemorrhage, adhesions (synechiae and secondary sterility, special attention should be paid to the diagnosis of high-risk pregnancies in prenatal clinics.

    Full Text Available Abstract Background Treatment effectiveness of Helicobacter pylori varies regionally and is decreasing worldwide, principally as a result of antibiotic resistant bacterium. Tetracycline is generally included in second line H. pylori eradication regimens. In Brazil, a high level of tetracycline resistance (TetR is mainly associated with AGA926-928TTC 16 S rDNA nucleotide substitutions. As H. pylori culture is fastidious, we investigated the primary occurrence of H. pylori 16 S rDNA high level TetR genotype using a molecular approach directly on gastric biopsies of dyspeptic patients attending consecutively at Hospital das Clinicas of Marilia, São Paulo, Brazil. Methods Gastric biopsy specimens of 68 peptic ulcer disease (PUD and 327 chronic gastritis (CG patients with a positive histological diagnosis of H. pylori were investigated for TetR 16 S rDNA genotype through a molecular assay based on amplification of a 16 S rDNA 545 bp fragment by polymerase chain reaction and HinfI restriction fragment length polymorphism (PCR/RFLP. Through this assay, AGA926-928TTC 16 S rDNA TetR genotype resulted in a three DNA fragment restriction pattern (281, 227 and 37 bp and its absence originated two DNA fragments (264 and 281 bp due to a 16 S rDNA conserved Hinf I restriction site. Results The 545 bp 16 S rDNA PCR fragment was amplified from 90% of gastric biopsies from histological H. pylori positive patients. HinfI RFLP revealed absence of the AGA926–928TTC H. pylori genotype and PCR products of two patients showed absence of the conserved 16 S rDNA HinfI restriction site. BLASTN sequence analysis of four amplicons (two conserved and two with an unpredicted HinfI restriction pattern revealed a 99% homology to H. pylori 16 S rDNA from African, North and South American bacterial isolates. A nucleotide substitution abolished the conserved HinfI restriction site in the two PCR fragments with unpredicted HinfI RFLP, resulting in an

    Universal usability of World Wide Web (Web) environments—that is, having 90% of households as successful users—requires universal access, usability, and universal design. Factors such as Web technology and user-centered design contribute to universal access and usability, but key to universal usability is a universal design methodology. Universal design principles for the Web follow from universal design principles for the built environment, and emphasize perceptibility, self-explanation, and tailorability for the user. Universally usable Web environments offer the benefit of expanded participation, as well as the unanticipated benefits that generally follow from innovative design initiatives. However, to achieve Web universal usability, Web designers need tools that facilitate the design of intuitive interfaces without sacrificing universal access.

    The model of the universe is considered in which background of the universe is not defined by the matter but is a priori specified as a homogenous and isotropic flat space. The scale factor of the universe follows the linear law. The scale of mass changes proportional to the scale factor. This leads to that the universe has the fractal structure with a power index of 2.

    Full Text Available RESUMEN: Autores como Poliakov, Anthony D. Smith o Paul Veyne han escrito páginas muy interesantes sobre los mitos o relatos de origen y el papel que éstos han jugado en el surgimiento de las identidades étnicas y nacionales. En línea con estos trabajos, en el presente ensayo se analiza el mito vasco y la cronología de la formación de los rasgos definitorios de la etnia vasca. El análisis de los relatos de García de Salazar y del Nobiliario del conde don Pedro Alfonso permiten extraer interesantes conclusiones sobre las leyendas de don Zuría, los orígenes de la Casa de Haro y la etnia vasca. Las transformaciones en la sociedad hidalga vizcaína del siglo XVI que motivaron cambios en el enunciado del mito de la batalla de Arrigorríaga, las causas que explican la leyenda del licenciado Andrés de Poza o la reescritura que de ese mismo mito de origen llevará a cabo mucho después el fundador del nacionalismo vasco son otros tantos temas tratados en este artículo. ABSTRACT: Authors such as Poliakov, Anthony D. Smith or Paul Veyne have written some very interesting pages on myths or stories of origins and the roles these have played in the forming of ethnic or national identities. In line with this work, the present essay analyzes the Basque myth and the chronology of the formation of the distinctive traits of the Basque ethnic group. Analysis of the stories of García de Salazar and of the genealogical work of Conde Don Pedro Alfonso allows us to draw interesting conclusions about the legends of Don Zuría, the origins of the House of Haro and the Basque ethnic group. The transformations in the noble society of Biscay in the 16th century that motivated changes in the telling of the myth of the Battle of Arrigoriaga, the causes explaining the legend of the gradúate Andrés de Poza or the rewriting of the same myth of origin that the founder of Basque nationalism would undertake much later are some of the other topics dealt with in this

    Turcan and Gulieva deepen our theoretical understanding of the process of university internationalisation by exploring the relationship between university internationalisation and university autonomy. They conjecture that the process of university internationalisation and its sustainability...... are determined by the structure and exercise of university autonomy settings at home and in the host countries, and that the process itself cannot be successfully achieved and maintained without changes in the autonomy settings. The key question the authors ask is to what degree universities, in embracing new......, dissimilar, and sometimes conflicting dimensions of the financial, legal, organisational, staffing, and academic autonomy of the host country, are compromising key aspects of their own autonomy and core mission?...

The study period was from 2000 to 2005. Radiological outcome was assessed using Cobb angle measurement pre and postoperatively, hence assessing percentage correction. The lower instrumented vertebra was taken as the neutral vertebra and the level was recorded. Functional outcome was determined using the Scoliosis Research Society patient administered questionnaire. All patients were called to the clinic and asked to fill in the form. Those patients who were out of the city were mailed the forms and requested via telephone to complete and return.Results: Of the 20 patients operated on, twelve were female and eight were male. The average age at operation was 12.7 years. The mean Cobb angle was 69° preoperatively and 20° postoperatively, representing a percentage correction of 71%. The average duration of follow-up was 3.6 years. There was one major complication involving neurological injury post-op and two minor complications involving wound infection. The average Scoliosis Research Society score (on a scale of 1–5, with 5 being best for pain was 4.5, self-image was 4.2, functional status was 4.1, mental status was 3.8, and satisfaction was 4.4. There was no relationship between the percentage correction of scoliosis and the functional outcome

    In late sixteenth century, with the link arising that Tibetan-Buddhism began to wide spread across the mongolian tribes, the close political and religious ties were established between mongolia and tibet. In 1636, four tribes of Oirat Mongolian launched the conquest of Qinghai-Tibet. After having oc-cupied Qinghai, Choros Tribe, Durbet Tribe and Turhute Tribe came back to the north of Tianshan Mountains, but Gushri Khan led the Hoshot Tribe to stay in Qinghai. In 1640 and 1642, as the apolo-getics dharmaraja of the Gelug Sect, Gushri Khan eliminated the Baili Chieftain and Tsangpa Khan II in Kham Region and gTsang, gradually unifying all of the Qinghai-Tibet Plateau. This paper plans to clar-ify the main events and the relationship of different parties in the process.%16世纪后期,藏传佛教在蒙古各部中开始广泛传播,蒙藏之间以此为纽带建立起了紧密的政治和宗教关系。1636年,在格鲁派求援的情况下,卫拉特蒙古四部联军展开了用兵青藏的征程。占领青海之后,绰罗斯部、杜尔伯特部和土尔扈特部部众返回天山以北,和硕特部固始汗率本部继续留驻青海。1640年和1642年,固始汗以格鲁派护教法王的身份分别在康区和后藏擒杀白利土司和藏巴汗二世,逐步统一了整个青藏高原。本文拟对这一过程中的主要事件和各方关系进行梳理。

So much so that that the ISS outreach is now routinely expected to participate in many of the international radiology conferences in that part of the world. The organizational planning for an outreach visit to Kenya took place over a 3-year period. Eventually a double-headed event; the seventh and eighth sub-Saharan outreach efforts were organized in Nairobi and in Mombasa, Kenya. The Nairobi outreach was an educational course on musculoskeletal imaging at the University of Nairobi and the Aga Khan University in Nairobi from 26 to 28 May 2015. The Mombasa outreach was organized in collaboration with the African Society of Radiology (ASR) at their annual meeting in Mombasa from 30 May to 2 June 2015. (orig.)

    As Pakistan becomes industrialized, the development of human resources is essential to addressing emerging health problems. The Fogarty International Center (FIC)-funded University of Alabama at Birmingham (UAB)-Aga Khan University (AKU) ITREOH initiative has been instrumental in filling the gaps in environmental and occupational health (EOH) training and research. Because of travel impediments to Pakistan, a regional short-term training program was implemented in Nepal and Sri Lanka. Workshop participants were from Pakistan, Nepal, Sri Lanka, India, and Bangladesh. The training programs enhanced north-to-south and south-to-south collaboration in research and training in South Asia. A major impact is the development of a certificate program in EOH at AKU. Research initiatives of regional and/or global concern are also under way in the other participating countries. The combination of face-to-face training with Web-based interaction for follow-up was optimal for short-term training.

A quantitative design was employed in this study to answer the two research questions of the present study. The quantitative data was obtained from the responses of 180 undergraduates in a questionnaire adapted from the study by Noor and Amir (2009 on vocabulary learning strategies proposed by Gu and Johnson (1996. The questionnaire comprised of 45 close-ended items on four broad vocabulary learning strategies, metacognitive regulation strategy, cognitive strategy, memory strategy, and activation strategy. Descriptive statistics was run in SPSS to obtain the results. The independent-samples t-test was run to test for statistically significant differences if any in the use of vocabulary learning strategies across the undergraduates of two universities. However, cognitive regulation strategy, and activation strategy emerged as the most influential source of learning new English words. The findings also revealed that there were no statistically significant differences found in practicing vocabulary learning strategies between undergraduates of SBKWU and UOB. The findings of the study have implications on enhancing teaching and learning by acquainting students with vocabulary learning strategies that can enhance their vocabulary in English language and can result to boost up their proficiency in this language.

    Universe Awareness (UNAWE) is an educational programme coordinated by Leiden University that uses the beauty and grandeur of the Universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age.UNAWE's twofold vision uses our Universe to inspire and motivate very young children: the excitement of the Universe provides an exciting introduction to science and technology, while the vastness and beauty of the Universe helps broaden the mind and stimulate a sense of global citizenship and tolerance. UNAWE's goals are accomplished through four main activities: the coordination of a global network of more than 1000 astronomers, teachers and educators from more than 60 countries, development of educational resources, teacher training activities and evaluation of educational activities.Between 2011 and 2013, EU-UNAWE, the European branch of UNAWE, was funded by the European Commission to implement a project in 5 EU countries and South Africa. This project has been concluded successfully. Since then, the global project Universe Awareness has continued to grow with an expanding international network, new educational resources and teacher trainings and a planned International Workshop in collaboration with ESA in October 2015, among other activities.

    The forest of Khan MA National Nature Reserve in Inner Mongolia was conducted to investigate the dynamic changes of the number and structure of forest resources from 1954 to 2001 mainly based on the forest resource investigation inventory in 1954, 1989 and 2001. The results indicate that the forest resources have taken place tremendous change from 1954 to 2001. The forest land increases by 22. 8% , the forest coverage enhances by 27.9% and the storage per hectare increases by 40%. The reasons mainly lie in the land-type transformation, for example, the open forest land changes into the forest land, the shrub land changes into the open forest land due to natural regeneration, and the nonstocked land changed into the forest land gradually. From the changes of species structure, Larix gmelinii is also in the dominant position and increasingly significant, and the other native tree species also increase. From 1954 to 2001, the area of L gmelinii is from 62 912 hm2 to 87 580 hm2 , increasing by 39% . The area of Belula platyhylla is from 1 334 hm2 to 4 094 hm2 , increasing by 151 % . As the associated tree species originally, Chosenia maerolepis and Populus suaveolens are the stand forest with certain area, increasing by 91 hm2 and 74 hm2 from 1954 to 2001. From the changes of the age class structure and the natural progression between each age group, the area and the stock of the high age class forest are in the dominant position in 50 years. Through the protection for nearly 50 years, the characteristics of the native coniferous and original nature community still maintain stabce. As the climax community, L. gmelinii community keeps the stable and original state of virgin forest in cold-temperate zone. Forest resource and forest function are used fully with significant effects.%以内蒙古汗马国家级自然保护区的森林为研究对象,根据1954年、1989年和2001年的森林资源调查资料,对其森林资源的数量、结构等方面的动态变化进

One option in this region is the pedicled fasciocutaneous flap based on perforators of the peroneal artery. In this case series, we present our experience of the peroneal island pedicled flap for reconstruction of lower extremity wounds.Methods: Records of 18 cases of peroneal island flap admitted consecutively to the Section of Orthopedics at Aga Khan University Hospital from January 1996 to December of 2009 were studied and their outcomes determined.Results: The most common indication for coverage was open wounds due to a road traffic accident (n = 10, followed by burns (n = 3. The most common area exposed was the lower third of the leg followed by the middle third. The tibia was exposed in 11 patients. The flaps ranged in size from 35 cm2 to over 200 cm2. In 13 patients, the flaps healed uneventfully, while in the remaining five there was partial flap necrosis. In four of the latter patients, the residual wound healed with conservative measures only, but the fifth patient required further surgery to achieve acceptable coverage.Conclusion: The peroneal artery flap appears to be a simple, useful, and reliable flap in the armamentarium of the surgeon when planning soft tissue coverage of the lower extremity.Keywords: leg injuries, surgical flaps, lower extremity

    Full Text Available Dengue fever (DF is an acute febrile illness that follows a self-limiting course. However, some patients suffer from complications, including myocarditis, due to the involvement of other organs. A child presented at the Aga Khan University Hospital in Karachi, Pakistan, in June 2013 with a high-grade fever, malaise and epigastric pain radiating to the chest. Positive DF antigen and immunoglobulin M assays confirmed the diagnosis of DF. Persistent bradycardia with low blood pressure led to further cardiac investigations which showed a decreased ejection fraction and raised serum cardiac enzymes, indicating myocardial damage. With supportive care and use of inotropes, the spontaneous normalisation of cardiac enzyme levels and ejection fraction was observed. The child was discharged five days after admission. This case highlights the importance of identifying myocarditis in DF patients suffering from cardiac symptoms that are not explained by other potential aetiologies. Awareness, early suspicion and supportive care are essential to ensure favourable outcomes.

    In this paper we have proposed a method for lungs nodule detection from computed tomography (CT) scanned images by using Genetic Algorithms (GA) and morphological techniques. First of all, GA has been used for automated segmentation of lungs. Region of interests (ROIs) have been extracted by using 8 directional searches slice by slice and then features extraction have been performed. Finally SVM have been used to classify ROI that contain nodule. The proposed system is capable to perform fully automatic segmentation and nodule detection from CT Scan Lungs images. The technique was tested against the 50 datasets of different patients received from Aga Khan Medical University, Pakistan and Lung Image Database Consortium (LIDC) dataset.

Patients presenting with symptoms of fever, bleeding, and rash cannot be distinguished without appropriate testing. We report data on 354 samples tested for CCHFV at The Aga Khan University Hospital in Pakistan between 2007 and 2013. All samples were tested for the presence of CCHFV RNA. Some samples were also tested for DENV RNA, NS-1 antigen, and/or reactive immunoglobulin M antibodies. Of 354 clinical specimens screened for CCHFV, 52 specimens were positive, with 24 cases in 2013 alone. Most cases were from Sindh and Baluchistan, which border other CCHFV-endemic regions: Iran and Afghanistan. Among CCHFV-negative samples, 168 samples were tested for DENV, and 36% of these samples were found to be DENV-positive. Rapid differentiation of CCHFV and DENV can prevent nosocomial transmission and result in time and cost savings for patients and healthcare workers. PMID:25311694

    This is a case report of a patient who presented to the Aga Khan University Hospital with generalized abdominal lymphadenopathy and high-grade fever. Due to ambiguous clinical findings, which were suggestive of either abdominal tuberculosis, or a lymphoma, the patient was started on empirical anti-tuberculous treatment due to the endemicity of tuberculosis in this region. The blood culture reports, however, were reported to grow colonies of Salmonellaparatyphi A; thus the diagnosis of the patient was changed to enteric fever, and the patient improved on the subsequently started therapy of ceftriaxone 2 000 mg bid. To the best of our knowledge, this is the first reported case of a patient suffering from enteric fever whose primary clinical findings were abdominal lymphadenopathy and fever.

    Full Text Available Writing in the University is a basic necessity and a long-range educational purpose. One of the basic characteristics of the university context is that it requires writing both as a tool of communication and as a source of intellectual stimulation. After establishing the basic features of academic writing, this article analyzes the role of writing for students (writing to learn and for teachers (write to plan, to reflect, to document what has been done. The article also discusses the contributions of writing for both students and teachers together: writing to investigate. Finally, going beyond what writing is as academic tool, we conclude with a more playful and creative position: writing for pleasure and enjoyment.

    University Physics provides an authoritative treatment of physics. This book discusses the linear motion with constant acceleration; addition and subtraction of vectors; uniform circular motion and simple harmonic motion; and electrostatic energy of a charged capacitor. The behavior of materials in a non-uniform magnetic field; application of Kirchhoff's junction rule; Lorentz transformations; and Bernoulli's equation are also deliberated. This text likewise covers the speed of electromagnetic waves; origins of quantum physics; neutron activation analysis; and interference of light. This publi

    Richman, Barbara T.

    In the past year, an increasing number of individual academic institutions have lobbied in Congress for new science facilities funds thus circumventing the traditional peer review process of evaluating the merits of such facilities. As an attempt to stem this rising tide, the National Academy of Sciences (NAS) governing council and the Association of American Universities (AAU) recently and independently issued strong statements condemning lobbying by individual universities and enthusiastically supporting the peer review system.“Informed peer judgments on the scientific merits of specific proposals, in open competition, should be a central element in the awarding of all federal funds for science,” the NAS resolution stated. AAU, meanwhile, implored “scientists, leaders of America's universities, and members of Congress” to “refrain from actions that would make scientific decisions a test of political influence rather than a judgment on the quality of the work to be done.” Roughly 50 research institutions constitute AAU; the two AAU Canadian members did not vote on the consortium's statement.

    Human life is a staggeringly strange thing. On the surface of a ball of rock falling around a nuclear fireball in the blackness of a vacuum the laws of nature conspired to create a naked ape that can look up at the stars and wonder where it came from. What is a human being? Objectively, nothing of consequence. Particles of dust in an infinite arena, present for an instant in eternity. Clumps of atoms in a universe with more galaxies than people. And yet a human being is necessary for the question itself to exist, and the presence of a question in the universe - any question - is the most wonderful thing. Questions require minds, and minds bring meaning. What is meaning? I don't know, except that the universe and every pointless speck inside it means something to me. I am astonished by the existence of a single atom, and find my civilisation to be an outrageous imprint on reality. I don't understand it. Nobody does, but it makes me smile. This book asks questions about our origins, our destiny, and our place i...

    A way to separate irreducible unitary representations π for a Lie group G by moment sets is to use an infinite-dimensional overgroup G˜ and extensions of each representation π to a representation π˜ of G˜, in such a manner that the moment set of π˜ characterizes π. In this paper we propose a universal overgroup G˜, which is an infinite-dimensional Fréchet-Lie group. We extend each π to a Hamiltonian action π˜ of G˜. The moment set of π˜ characterizes π.

    On the 6th December 2008, in my role as Editor-in-Chief of the International Journal of Cardiology, I received an email from Professor Harold Garner of UT Southwestern Medical Center, Dallas. Professor Garner told me that using a new search engine methodology (eTBLAST) he and colleagues had identified a paper in the International Journal of Cardiology published in 1996 which had remarkable text and data similarity to an earlier paper published in 1992 in the New England Journal of Medicine. They had detected this similarity after randomly selecting citations from Medline and submitting them to the tool to find other highly similar citations as part of their NIH/R01 funded research on the ethics of publication. We have been notified that all such cases are reported in a database, Déjà Vu (http://spore.swmed.edu/dejavu/). We investigated the text of the two papers and we agreed that there was such a similarity that the later paper must have plagiarized the earlier paper, and in doing so infringed the copyright. In accordance with our previously published standards on ethical publishing in the Journal we hereby retract the paper "The prognostic value of serum troponin T in unstable angina. Gökhan Cin V, Gök H, Kaptanoğlu B. Int J Cardiol. 1996 Mar;53(3):237-44.".

    Is Universal Grammar a universal grammar? From Chomsky's hierarchy we deduce that for each grammar there is a Turing machine, and conversely. Following this equivalence, it is immediate to conclude that a universal Turing machine is equivalent to a universal grammar. Meanwhile, in linguistics, Universal Grammar is the human brain circuitry that implements the faculty of language. So the definitive answer is achieved only when we show that the human brain is Turing complete, and that language ...

    Triple molybdates AgA3R(MoO4)5 (A=Mg, R=Cr, Fe; A=Mn, R=Al, Cr, Fe, Sc, In) of the NaMg3In(MoO4)5 type were synthesized and single crystals of AgMg3R(MoO4)5 (R=Cr, Fe) were grown. In their structures, the MoO4 tetrahedra, pairs and trimers of edge-shared (Mg, R)O6 octahedra are connected by common vertices to form a 3D framework. Large framework cavities involve Ag+ cations disordered on three nearby positions with CN=3+1 or 4+1. Alternating (Mg, R)O6 octahedra and MoO4 tetrahedra in the framework form quadrangular windows penetrable for Ag+ at elevated temperatures. Above 653-673 K, the newly obtained molybdates demonstrate abrupt reduction of the activation energy to 0.4-0.6 eV. At 773 K, AgMg3Al(MoO4)5 shows electric conductivity 2.5·10-2 S/cm and Ea=0.39 eV compatible with characteristics of the best ionic conductors of the NASICON type.

Population-based data on IPV from Muslim societies are scarce, and Pakistan is no exception. This study was conducted among women residing in urban Karachi, to estimate the prevalence and frequency of different forms of IPV and their associations with sociodemographic factors.Methods: This cross-sectional community-based study was conducted using a structured questionnaire developed by the World Health Organisation for research on violence. Community midwives conducted face-to-face interviews with 759 married women aged 25–60 years.Results: Self-reported past-year and lifetime prevalence of physical violence was 56.3 and 57.6%, respectively; the corresponding figures for sexual violence were 53.4% and 54.5%, and for psychological abuse were 81.8% and 83.6%. Violent incidents were mostly reported to have occurred on more than three occasions during the lifetime. Risk factors for physical violence related mainly to the husband, his low educational attainment, unskilled worker status, and five or more family members living in one household. For sexual violence, the risk factors were the respondent’s low educational attainment, low socioeconomic status of the family, and five or more family members in one household. For psychological violence, the risk factors were the husband being an unskilled worker and low

    2001-01-01

    Universal grammar specifies the mechanism of language acquisition. It determines the range of grammatical hypothesis that children entertain during language learning and the procedure they use for evaluating input sentences. How universal grammar arose is a major challenge for evolutionary biology. We present a mathematical framework for the evolutionary dynamics of grammar learning. The central result is a coherence threshold, which specifies the condition for a universal grammar to induce coherent communication within a population. We study selection of grammars within the same universal grammar and competition between different universal grammars. We calculate the condition under which natural selection favors the emergence of rule-based, generative grammars that underlie complex language.

  11. Universities scale like cities.

    Directory of Open Access Journals (Sweden)

    Anthony F J van Raan

    Full Text Available Recent studies of urban scaling show that important socioeconomic city characteristics such as wealth and innovation capacity exhibit a nonlinear, particularly a power law scaling with population size. These nonlinear effects are common to all cities, with similar power law exponents. These findings mean that the larger the city, the more disproportionally they are places of wealth and innovation. Local properties of cities cause a deviation from the expected behavior as predicted by the power law scaling. In this paper we demonstrate that universities show a similar behavior as cities in the distribution of the 'gross university income' in terms of total number of citations over 'size' in terms of total number of publications. Moreover, the power law exponents for university scaling are comparable to those for urban scaling. We find that deviations from the expected behavior can indeed be explained by specific local properties of universities, particularly the field-specific composition of a university, and its quality in terms of field-normalized citation impact. By studying both the set of the 500 largest universities worldwide and a specific subset of these 500 universities--the top-100 European universities--we are also able to distinguish between properties of universities with as well as without selection of one specific local property, the quality of a university in terms of its average field-normalized citation impact. It also reveals an interesting observation concerning the working of a crucial property in networked systems, preferential attachment.

    In the last decades, renormalization group (RG) ideas have been applied to describe universal properties of different routes to chaos (quasi-periodic, period doubling or tripling, Siegel disc boundaries, etc). Each of the RG theories leads to universal scaling exponents which are related to the action of certain RG operators. The goal of this announcement is to show that there is a principle that organizes many of these scaling exponents. We give numerical evidence that the exponents of different routes to chaos satisfy approximately some arithmetic relations. These relations are determined by combinatorial properties of the route and become exact in an appropriate limit. (fast track communication)

    We show that in the isentropic scenario the first order thermodynamical particle creation model gives an emergent universe solution even when the chemical potential is non-zero. However there exists no emergent universe scenario in the second order non-equilibrium theory for the particle creation model. We then point out a correspondence between the particle creation model with barotropic equation of state and the equation of state giving rise to an emergent universe without particle creation in spatially flat FRW cosmology.

That is, the ideal gas equation of state is suitable for the Singular point and the universe. Maybe someone consider that, there is no vessel can accommodate radiation, it is because the Ordinary container is too small to accommodate, if the radius of your container is the distance that Light through an hour, would you still think it can't accommodates radiation? Modern scientific determinate that the radius of the universe now is about 1027 m, assuming that the universe is a sphere whose volume is approximately: V = 4.19 × 1081 cubic meters, the temperature radiation of the universe (cosmic microwave background radiation temperature of the universe, should be the closest the average temperature of the universe) T = 3.15k, radiation pressure P = 5 × 10-6 N / m 2, according to the law of ideal gas state equation, PV / T = constant = 6 × 1075, the value of this constant is the universe, The singular point should also equal to the constant Author: hanyongquan

    1991-01-01

    'There is evidence to suggest that our world and everything in it - from snowflakes to maple trees to falling stars and spinning electrons - are only ghostly images, projections from a level of reality literally beyond both space and time.' This is the astonishing idea behind the holographic theory of the universe, pioneered by two eminent thinkers: physicist David Bohm, a former protege of Albert Einstein, and quantum physicist Karl Pribram. The holographic theory of the universe encompasses consciousness and reality as we know them, but can also explain such hitherto unexplained phenomena as telepathy, out-of-body experiences and even miraculous healing. In this remarkable book, Michael Talbot reveals the extraordinary depth and power of the holographic theory of the universe, illustrating how it makes sense of the entire range of experiences within our universe - and in other universes beyond our own.

  10. Universe opacity and EBL

    CERN Document Server

    Vavrycuk, Vaclav

    2016-01-01

    The observed extragalactic background light (EBL) is affected by light attenuation due to absorption of light by galactic and intergalactic dust in the Universe. Even galactic opacity of 10-20 percent and minute universe intergalactic opacity of $0.01\\,\\mathrm{mag}\\,h\\,\\mathrm{Gpc}^{-1}$ at the local Universe have a significant impact on the EBL because obscuration of galaxies and density of intergalactic dust increase with redshift as $\\left(1+z\\right)^3$. Consequently, intergalactic opacity increases and the Universe becomes considerably opaque at $z > 3$. Adopting realistic values for galactic and intergalactic opacity, the estimates of the EBL for the expanding dusty universe are close to observations. The luminosity density evolution fits well measurements. The model reproduces a steep increase of the luminosity density at $z3.5$.

This consisted of patients undergoing unilateral and bilateral knee arthroplasty. Preoperatively, Knee Society Knee and Function Scores were calculated. After a minimum of 3 years postoperatively Knee Society Knee and Function Scores as well as the Clinical Anterior Knee Pain Rating were calculated and analysis done to check for differences.Results: Seventy-five patients were recruited in each arm; 135 patients had bilateral and 15 had unilateral knee arthroplasty. The mean preoperative knee score was 40.4 for the resurfacing group and 40.60 for the nonresurfacing group (P = 0.45. This improved postoperatively to 93.67 and 94.23 respectively, with no difference between the two groups (P = 0.67. The mean preoperative function score was 45.50 for resurfaced patellae and 45.83 for nonresurfaced. This improved to 89.67 and 90.50, respectively, again with no difference (P = 0.51. Postoperative Clinical Anterior Knee Pain Rating was a mean of 0.1 for resurfaced and 0.13 for nonresurfaced patellas, with no difference on analysis (P = 0.06. However, patients who had bilateral knee arthroplasty had a slightly higher Clinical Anterior Knee Pain Rating than those who had single knee surgery (P = 0.046 irrespective of whether the patellar was resurfaced or not.Conclusion: In

    In the public eye, universities are typically acknowledged for providing two kinds of services: education and research. But universities do much more—and with a long shelf life, too. Universities also promote classic virtues like to seize the day—carpe diem; dare to know—sapere aude; the value...... of hard work—semper ardens; and to hurry slowly with reflection—festina lente. Good old-fashioned Latin strong suits. The narrative of instilling these virtues is hardly ever advertised by academia. Why not? Partly because they sound almost archaic. But they don’t have to be—especially not in this digital...

  14. The Dark Universe Riddle

    Capistrano, A J S

    2008-01-01

    In this work we review some of the theoretical efforts and experimental evidences related to Dark matter and Dark energy problems in the universe. These dilemmas show us how incomplete our knowledge of gravity is, and how our concepts about the universe must at least be revised. Mainly, on the Wilkinson Microwave Anisotropy Probe (WMAP) fifth year, the data indicates that more than 90% of the total energy density of the universe is dark. Here we discuss the impact of these phenomena imprint on gravitational and quantum field theory's standard history. Moreover, we point out some recent and upcoming projects on Cosmology in a quest to understand theses issues thoroughly.

    We describe the Universal Recommender, a recommender system for semantic datasets that generalizes domain-specific recommenders such a content-based, collaborative, social, bibliographic, lexicographic, hybrid and other recommenders. In contrast to existing recommender systems, the Universal Recommender applies to any dataset that allows a semantic representation. We describe the scalable three-stage architecture of the Universal Recommender and its application to Internet Protocol Television (IPTV). To achieve good recommendation accuracy, several novel machine learning and optimization problems are identified. We finally give a brief argument supporting the need for machine learning recommenders.

If current typhoid-protein conjugate vaccines live up to their promise of higher efficacy, longer duration of protection, and efficacy in young children, typhoid vaccine use will be a critical component of short- and medium-term disease control strategies. Typhoid control could be accelerated if the global framework includes plans for accelerated introduction of the conjugate typhoid vaccine in developing countries.

    2015-01-01

    The separate universe conjecture states that in General Relativity a density perturbation behaves locally (i.e. on scales much smaller than the wavelength of the mode) as a separate universe with different background density and curvature. We prove this conjecture for a spherical compensated tophat density perturbation of arbitrary amplitude and radius in $\\Lambda$CDM. We then use Conformal Fermi Coordinates to generalize this result to scalar perturbations of arbitrary configuration and scale in a general cosmology with a mixture of fluids, but to linear order in perturbations. In this case, the separate universe conjecture holds for the isotropic part of the perturbations. The anisotropic part on the other hand is exactly captured by a tidal field in the Newtonian form. We show that the separate universe picture is restricted to scales larger than the sound horizons of all fluid components. We then derive an expression for the locally measured matter bispectrum induced by a long-wavelength mode of arbitrary...

    The problems encountered in mixing industrial and university research goals can be major, but so can the benefits. The National Science Board (NSB) recently released a report on “University-Industry Research Relationships: Selected Studies” (U.S. Government Printing Office, Washington, DC, 1983). It is an analysis of the much-discussed new trend toward increased industrial funding of university research projects.University laboratories cannot generally solve industry's R&D problems. Success for the corporation in sponsoring academic research is realized in the value of cooperative research programs as training exercises for future industrial scientists. An occasional patent arising from such a project is considered an added benefit, not a primary goal.

    Einstein's static model is the first relativistic cosmological model. The model is static, finite and of spherical spatial symmetry. I use the solution of Einstein's field equations in a homogeneous and isotropic universe -- Friedmann's equation -- to calculate the radius of curvature of the model (also known as "Einstein's universe"). Furthermore, I show, using a Newtonian analogy, the model's mostly known feature, namely, its instability under small perturbations on the state of equilibrium.

    A universal tiler is a convex polyhedron whose every cross-section tiles the plane. In this paper, we introduce a certain slight-rotating operation for cross-sections of pentahedra. Based on a selected initial cross-section and by applying the slight-rotating operation suitably, we prove that a convex polyhedron is a universal tiler if and only if it is a tetrahedron or a triangular prism.

    The principal objectives of the Fossil Energy Program are to seek new ideas, new data, fundamental knowledge that will support the ongoing programs, and new processes to better utilize the nation's fossil energy resources with greater efficiency and environmental acceptability. Toward this end, the Department of Energy supports research projects conducted by universities and colleges to: Ensure a foundation for innovative technology through the use of the capabilities and talents in our academic institutions; provide an effective, two-way channel of communication between the Department of Energy and the academic community; and ensure that trained technical manpower is developed to carry out basic and applied research in support of DOE's mission. Fossil Energy's university activities emphasize the type of research that universities can do best - research to explore the potential of novel process concepts, develop innovative methods and materials for improving existing processes, and obtain fundamental information on the structure of coal and mechanisms of reactions of coal, shale oil, and other fossil energy sources. University programs are managed by different Fossil Energy technical groups; the individual projects are described in greater detail in this book. It is clear that a number of research areas related to the DOE Fossil Energy Program have been appropriate for university involvement, and that, with support from DOE, university scientific and technical expertise can be expected to continue to play a significant role in the advancement of fossil energy technology in the years to come.

    Using the known result that the nucleation of baby universes in correlated pairs is equivalent to spacetime squeezing, we show in this Letter that there exists a T-duality symmetry between two-dimensional warp drives, which are physically expressible as localized de Sitter little universes, and two-dimensional Tolman-Hawking and Gidding-Strominger baby universes respectively correlated in pairs, so that the creation of warp drives is also equivalent to spacetime squeezing. Perhaps more importantly, it has been also seen that the nucleation of warp drives entails a violation of the Bell's inequalities, and hence the phenomena of quantum entanglement, complementarity and wave function collapse. These results are generalized to the case of any dynamically accelerating universe filled with dark or phantom energy whose creation is also physically equivalent to spacetime squeezing and to the violation of the Bell's inequalities, so that the universe we are living in should be governed by essential sharp quantum theory laws and must be a quantum entangled system.

    Sheykhi, Ahmad; Wang, Bin

    2012-01-01

    We investigate the thermodynamical properties of the apparent horizon in a fractal universe. We find that one can always rewrite the Friedmann equation of the fractal universe in the form of the entropy balance relation $ \\delta Q=TdS+Td\\tilde{S}$, where $ \\delta Q $ and $ T $ are the energy flux and Unruh temperature seen by an accelerated observer just inside the apparent horizon, and $d\\tilde{S}$ is the entropy production term due to nonequilibrium thermodynamics of fractal universe. This shows that in a fractal universe, a treatment with nonequilibrium thermodynamics of spacetime may be needed. We also study the generalized second law of thermodynamics in the framework of fractal universe. When the temperature of the apparent horizon and the matter fields inside the horizon are equal, i.e. $T=T_h$, the generalized second law of thermodynamics can be fulfilled provided the deceleration and the equation of state parameters ranges either as $-1 \\leq q < 0 $, $- 1 \\leq w < - 1/3$ or as $q<-1$, $w<...

    The last century has seen enormous progress in our understanding of the Universe. We know the life cycles of stars, the structure of galaxies, the remnants of the big bang, and have a general understanding of how the Universe evolved. We have come remarkably far using electromagnetic radiation as our tool for observing the Universe. However, gravity is the engine behind many of the processes in the Universe, and much of its action is dark. Opening a gravitational window on the Universe will let us go further than any alternative. Gravity has its own messenger: Gravitational waves, ripples in the fabric of spacetime. They travel essentially undisturbed and let us peer deep into the formation of the first seed black holes, exploring redshifts as large as z ~ 20, prior to the epoch of cosmic re-ionisation. Exquisite and unprecedented measurements of black hole masses and spins will make it possible to trace the history of black holes across all stages of galaxy evolution, and at the same time constrain any devia...

    We exploit the parallel between dynamical black holes and cosmological spacetimes to describe the evolution of Friedmann-Lemaître-Robertson-Walker universes from the point of view of an observer in terms of the dynamics of the apparent horizon. Using the Hayward-Kodama formalism of dynamical black holes, we clarify the role of the Clausius relation to derive the Friedmann equations for a Universe, in the spirit of Jacobson’s work on the thermodynamics of spacetime. We also show how dynamics at the horizon naturally leads to the quantum-mechanical process of Hawking radiation. We comment on the connection of this work with recent ideas to consider our observable Universe as a Bose-Einstein condensate and on the corresponding role of vacuum energy.

The importance of recollapse for observational astrophysics is briefly discussed, and particular attention is given to the implications of maximal hypersurfaces and to recollapse in S3 Friedmann universes. It is conjectured that all globally hyperbolic C2 maximally extended spatially homogeneous closed universes with S3 or S2 x S1 topology and with stress-energy tensors obeying the strong-energy, positive-pressure, dominant-energy, and matter-regularity conditions do expand from an all-encompassing initial singularity to a maximal hypersurface and then recollapse to an all-encompassing final singularity.

    Full Text Available The question of identifying the properties of language that are specific human linguistic abilities, i.e. Universal Grammar, lies at the center of linguistic research. This paper argues for a largely Emergent Grammar in phonology, taking as the starting point that memory, categorization, attention to frequency, and the creation of symbolic systems are all nonlinguistic characteristics of the human mind. The articulation patterns of American English rhotics illustrate categorization and systems; the distribution of vowels in Bantu vowel harmony uses frequencies of particular sequences to argue against Universal Grammar and in favor of Emergent Grammar; prefix allomorphy in Esimbi illustrates the Emergent symbolic system integrating phonological and morphological generalizations. The Esimbi case has been treated as an example of phonological opacity in a Universal Grammar account; the Emergent analysis resolves the pattern without opacity concerns.

    Full Text Available University autonomy represented an additional argument against government interference in university education. From academic perspective, the diversification of funding sources and the introduction of changes in the funding mechanism represented positive factors in the evolution of higher education. It is obvious that most of the problems associated with underfunding of higher education are relevant because it affects the quality of education and overall performance of universities. Since the training costs per capita in the higher education system were the lowest compared with the same indicator in relation to vocational schools and colleges in the period of 2005 – 2009, it is clear that underfunding is real and requires necessary measures to be taken to remedy the situation

    We introduce "anamorphic" cosmology, an approach for explaining the smoothness and flatness of the universe on large scales and the generation of a nearly scale-invariant spectrum of adiabatic density perturbations. The defining feature is a smoothing phase that acts like a contracting universe based on some Weyl frame-invariant criteria and an expanding universe based on other frame-invariant criteria. An advantage of the contracting aspects is that it is possible to avoid the multiverse and measure problems that arise in inflationary models. Unlike ekpyrotic models, anamorphic models can be constructed using only a single field and can generate a nearly scale-invariant spectrum of tensor perturbations. Anamorphic models also differ from pre-big bang and matter bounce models that do not explain the smoothness. We present some examples of cosmological models that incorporate an anamorphic smoothing phase.

The Esimbi case has been treated as an example of phonological opacity in a Universal Grammar account; the Emergent analysis resolves the pattern without opacity concerns.

    Coleridge is a famous Lake poet during the romanticism period of English literature in 19th century. In his two representative works Kubla Khan and The Rime of the Ancient Mariner, the value of literature, poetics and aesthetics have been generally acknowledged and these two works have been translated by many Chinese translators. As one of the chief supporters and theory contributors, Venuti defines "foreignization" as an approach in which the translator leaves the author in peace, as much as possible, and moves the reader towards him. The paper aims at exploring the important role of foreignization in retaining the poetic value and aesthetic sense, through the analysis of the sources of mysterious elements in Coleridge' s poems. The theory of foreignization helps to broaden readers' vision and to reproduce the poet' s unique style fully. Therefore, translating by foreignization can preserve the beauty of foreign poems to the largest extent.%柯勒律治是19世纪初英国文学浪漫主义时期著名的湖畔派诗人,他的两首代表作品《忽必烈汗》和《古舟子咏》的文学、诗学和美学价值已经得到了西方学术界的认可并且曾被我国多位译者译介。韦努蒂作为异化理论的主要支持者和理论贡献者,指出“异化”是一种译者不干扰作者,而尽量使读者靠近作者的翻译方法。本文通过分析柯勒律治诗歌中神秘因素的主要来源,剖析异化理论在翻译实践中保留诗歌诗意价值和诗学关感的重要意义,指出,异化理论既能拓宽读者视野,又能充分表述诗人独特风格,最大限度保留诗歌关感。

    2005-07-01

    Our love of art, writes John Barrow, is the end product of millions of years of evolution. How we react to a beautiful painting or symphony draws upon instincts laid down long before humans existed. Now, in this enhanced edition of the highly popular The Artful Universe , Barrow further explores the close ties between our aesthetic appreciation and the basic nature of the Universe. Barrow argues that the laws of the Universe have imprinted themselves upon our thoughts and actions in subtle and unexpected ways. Why do we like certain types of art or music? What games and puzzles do we find challenging? Why do so many myths and legends have common elements? In this eclectic and entertaining survey, Barrow answers these questions and more as he explains how the landscape of the Universe has influenced the development of philosophy and mythology, and how millions of years of evolutionary history have fashioned our attraction to certain patterns of sound and color. Barrow casts the story of human creativity and thought in a fascinating light, considering such diverse topics as our instinct for language, the origins and uses of color in nature, why we divide time into intervals as we do, the sources of our appreciation of landscape painting, and whether computer-generated fractal art is really art. Drawing on a wide variety of examples, from the theological questions raised by St. Augustine and C.S. Lewis to the relationship between the pure math of Pythagoras and the music of the Beatles, The Artful Universe Expanded covers new ground and enters a wide-ranging debate about the meaning and significance of the links between art and science.

    2011-01-01

    This talk is about solving cosmological equations analytically without approximations, and discovering new phenomena that could not be noticed with approximate solutions. We found all the solutions of the Friedmann equations for a specific model, including all the zero-size-bounce solutions that do not violate the null energy condition, as well as all the finite-size-bounce solutions, and then discovered model independent phenomena. Among them is the notion of geodesic completeness for the geometry of the universe. From this we learned a few new general lessons for cosmology. Among them is that anisotropy provides a model independent attractor mechanism to some specific initial values for cosmological fields, and that there is a period of antigravity in the history of the universe. The results are obtained only at the classical gravity level. Effects of quantum gravity or string theory are unknown, they are not even formulated, so there are new theoretical challenges.

  20. Universality for quintessence

    CERN Document Server

    Cicciarella, F

    2016-01-01

    Several recent works suggested the possibility of describing inflation by means of a renormalization group equation. In this paper we discuss the application of these methods to models of quintessence. In this framework a period of exponential expansion corresponds to the slow evolution of the scalar field in the neighborhood of a fixed point. A minimal set of universality classes for models of quintessence is defined and the transition from a matter dominated to quintessence dominated universe is studied. Models in which quintessence is non-minimally coupled with gravity are also discussed. We show that the formalism proves to be extremely convenient to describe quintessence and moreover we find that in most of the models discussed in this work quintessence naturally takes over ordinary matter.

    In a large class of extra-dimensional models, a scalar degree of freedom known as the radion is long-lived, or even stable, on cosmological scales. In this paper we investigate the impact of radionactivity on the evolution of the universe. We demonstrate that whether the radion overcloses the universe, constitutes the dark matter, is the inflaton, the curvaton, or does not play any role in cosmology, depends crucially on the ratio between the energy densities stored in the radion and in the inflaton at the time of inflation. We discuss the general difficulties reconciling models with low compactification scale (i.e., TeV scale) with the simple picture of inflation.

We then turn attention to the present day context and show the dominance of strong interaction quark and gluon degrees of freedom in the early stage, helping to characterize the properties of the hot Universe. We focus attention on the current experimental insights about cosmic microwave background (CMB) temperature fluctuation, and develop a much improved understanding of the neutrino freeze-out, in this way paving the path to the opening of a direct connection of quark-gluon plasma (QGP) physics in the early Universe with the QCD-lattice, and the study of the properties of QGP formed in the laboratory.

    Full Text Available This article investigates the current data management practices of university researchers at an Intermountain West land-grant research university in the United States. Key findings suggest that researchers are primarily focused on the collection and housing of research data. However, additional research value exists within the other life cycle stages for research data—specifically in the stages of delivery and maintenance. These stages are where most new demands and requirements exist for data management plans and policies that are conditional for external grant funding; therefore, these findings expose a “gap” in current research practice. These findings should be of interest to academics and practitioners alike as findings highlight key management gaps in the life cycle of research data. This study also suggests a course of action for academic institutions to coalesce campus-wide assets to assist researchers in improving research value.

    2016-01-01

    We propose a design for an universal absorber, characterized by a resonance frequency that can be tuned from visible to microwave frequencies independently of the choice of the metal and the dielectrics involved. An almost resonant perfect absorption up to 99.8 % is demonstrated at resonance for all polarization states of light and for a very wide angular aperture. These properties originate from a magnetic Fabry-Perot mode that is confined in a dielectric spacer of $\\lambda/100$ thickness by a metamaterial layer and a mirror. An extraordinary large funneling through nano-slits explains how light can be trapped in the structure. Simple scaling laws can be used as a recipe to design ultra-thin perfect absorbers whatever the materials and the desired resonance wavelength, making our design truly universal.

    A true universal co-axial anaesthetic system has been designed. This system may be used either as a Mapleson A circuit during spontaneous ventilation or as a Mapleson D circuit during controlled ventilation. Conversion to either system may be conveniently carried out by interchanging the pop-off valve and fresh gas inlet, without disconnecting the system from the patient. Resistance to flow of both tubes has been measured and was found to be within acceptable limits. The efficiency of this system in a Mapleson A arrangement was compared with that of a conventional Magill circuit during spontaneous breathing in 2 conscious volunteers. It was shown that no significant difference exists between these systems eith regard to rebreathing, and that the universal co-axial system may be used as efficiently and economically as the Magill circuit during spontaneous ventilation. The co-axial system can be easily connected to a circle system, combining the advantages of the two systems.

    The present monograph is devoted to the theory of gravitation derived consequently as joint nonlinear realization of conformal and affine symmetries by means of Cartan differential forms. In the framework of the joint nonlinear realization of conformal and affine symmetries the interpretation of the last cosmological observational data of Ia Supernovae, anisotropy of the primordial radiation temperature and the mass spectrum of electroweak bosons, including the Higgs particle mass in the expected region ~ 125 GeV, is given. All these observational and experimental data testify to the vacuum energy dominance. The vacuum Casimir energy is a source of intensive cosmological quantum creation gravitons and electroweak bosons including Higgs particles from the empty Universe during the first 10^(-12) sec. The products of decay of the electroweak bosons give the matter content of the present day Universe, including primordial radiation and its baryon asymmetry.

    CERN Document Server

    Moss, Adam

    2009-01-01

    Structure in the Universe grew through gravitational instability from very smooth initial conditions. Energy conservation requires that the growing negative potential energy of these structures is balanced by an increase in kinetic energy. A fraction of this is converted into heat in the collisional gas of the intergalactic medium. Using a toy model of gravitational heating we attempt to link the growth of structure in the Universe and the average temperature of this gas. We find that the gas is rapidly heated from collapsing structures at around $z {\\sim} 10$, reaching a temperature ${>} 10^6$K today, depending on some assumptions of our simplified model. Before that there was a cold era from $z\\sim100$ to $\\sim10$ in which the matter temperature is below that of the Cosmic Microwave Background.

    2015-10-06

    Most of the mass in the universe is in the form of dark matter--a new type of nonbaryonic particle not yet detected in the laboratory or in other detection experiments. The evidence for the existence of dark matter through its gravitational impact is clear in astronomical observations--from the early observations of the large motions of galaxies in clusters and the motions of stars and gas in galaxies, to observations of the large-scale structure in the universe, gravitational lensing, and the cosmic microwave background. The extensive data consistently show the dominance of dark matter and quantify its amount and distribution, assuming general relativity is valid. The data inform us that the dark matter is nonbaryonic, is "cold" (i.e., moves nonrelativistically in the early universe), and interacts only weakly with matter other than by gravity. The current Lambda cold dark matter cosmology--a simple (but strange) flat cold dark matter model dominated by a cosmological constant Lambda, with only six basic parameters (including the density of matter and of baryons, the initial mass fluctuations amplitude and its scale dependence, and the age of the universe and of the first stars)--fits remarkably well all the accumulated data. However, what is the dark matter? This is one of the most fundamental open questions in cosmology and particle physics. Its existence requires an extension of our current understanding of particle physics or otherwise point to a modification of gravity on cosmological scales. The exploration and ultimate detection of dark matter are led by experiments for direct and indirect detection of this yet mysterious particle.

    Using Planck scale oscillators in the background dark energy in a model that parallels the theory of phonons, we deduce the Planck mass, the elementary particle mass scale, the mass of the Universe and a recently discovered residual energy in the cosmic background. We also deduce the Beckenstein temperature formula for black holes. Finally we show that the model explains the four minute time lag in thearrival of gamma photons from a recently observed gamma flare by the MAGIC telescope.

  18. Inflation in the universe

    1987-05-01

    The hot big bang cosmology, or the standard cosmology as it is appropriately known, is a highly successful model, providing a reliable and tested accounting of the Universe from 0.01 sec after the bang until today, some 15 Gyr later. However, very special initial data seem to be required in order to account for the observed smoothness and flatness of our Hubble volume and for the existence of the small primeval density inhomogeneities required for the formation of structure in the Universe. Inflation offers a means of accounting for these special initial data, which is based upon physics at sub-planck energy scales (<< m/sub pl/ approx. = 10/sup 19/ GeV) and is motivated by contemporary ideas in particle theory. Here I review the status of the 'Inflationary Paradigm'. At present essentially all inflationary models involve a very weakly-coupled (quantified by the presence of a dimensionless parameter of order 10/sup -12/ or so) scalar field which is displaced from the minimum of its potential. Regions of the Universe where the scalar field is initially displaced from its minimum undergo inflation as the scalar field relaxes, resulting in a Universe today which resembles ours in regions much larger than our present Hubble volume (approx. = 10/sup 28/ cm), but which on very large scales (>> 10/sup 28/ cm) may be highly irregular. The most conspicuous blemish on the paradigm is the lack of a compelling particle physics model to implement it. I also review some other unresolved issues, and discuss in detail the all important confrontation between inflation and observational data. Finally, I discuss the possibility that inflation leads to large-scale, primeval magnetic fields of sufficient strength to be of astrophysical interest. 123 refs., 4 figs.

  19. Universality and string theory

    Bachlechner, Thomas Christian

    The first run at the Large Hadron Collider has deeply challenged conventional notions of naturalness, and CMB polarization experiments are about to open a new window to early universe cosmology. As a compelling candidate for the ultraviolet completion of the standard model, string theory provides a prime opportunity to study both early universe cosmology and particle physics. However, relating low energy observations to ultraviolet physics requires knowledge of the metastable states of string theory through the study of vacua. While it is difficult to directly obtain infrared data from explicit string theory constructions, string theory imposes constraints on low energy physics. The study of ensembles of low energy theories consistent with ultra-violet constraints provides insight on generic features we might expect to occur in string compactifications. In this thesis we present a statistical treatment of vacuum stability and vacuum properties in the context of random supergravity theories motivated by string theory. Early universe cosmology provides another avenue to high energy physics. From the low energy perspective large field inflation is typically considered highly unnatural: the scale relevant for the diameter of flat regions in moduli space is sub-Planckian in regions of perturbative control. To approach this problem, we consider generic Calabi-Yau compactifications of string theory and find that super-Planckian diameters of axion fundamental domains in fact arise generically. We further demonstrate that such super-Planckian flat regions are plausibly consistent with theWeak Gravity Conjecture.

    Full Text Available This study aims at determining the skills of Graphics Department students of Fine Arts Faculties with regards evaluating the emblembs of universities. The study follows a general survey model and the research group consists of the seniors studying at Graphics Departments of Fine Arts Faculties of Anadolu, Başkent, Dumlupınar, Hacettepe, Marmara and Süleyman Demirel Universities. In the study, data regarding the evaluations and interpretations of students and experts about the university emblems were collected through qualitative methods of analysis. Content analysis was employed for analysing the qualitative data gathered through interviews. As a result of the study, it was observed that students had relevant knowledge regarding emblems and design principles, and they, while evaluating the emblems as a graphic product, were able to exhibit such cognitive skills as analysing, interpreting, explaining, noticing and correcting, were able to notice the problems and recommend ways of solution through criticizing, and that they were very approximate to the experts in their evaluations. Therefore, it could be asserted that the students receive a quality graphics education.

    2012-01-01

    Modified gravity models such as Ho\\v{r}ava-Lifshitz gravity or Einstein-{\\ae}ther theory violate local Lorentz invariance and therefore destroy the notion of a universal light cone. Despite this, in the infrared limit both models above possess static, spherically symmetric solutions with "universal horizons" - hypersurfaces that are causal boundaries between an interior region and asymptotic spatial infinity. In other words, there still exist black hole solutions. We construct a Smarr formula (the relationship between the total energy of the spacetime and the area of the horizon) for such a horizon in Einstein-{\\ae}ther theory. We further show that a slightly modified first law of black hole mechanics still holds with the relevant area now a cross-section of the universal horizon. We construct new analytic solutions for certain Einstein-{\\ae}ther Lagrangians and illustrate how our results work in these exact cases. Our results suggest that holography may be extended to these theories despite the very differen...

    Full Text Available Abstract Institutions should implement effective crisis communication strategies to manage their reputations in crisis situations. Thus, the negative perceptions that may occur because of crisis can be reduced and eliminated by continuously informing stakeholders. Therefore, various researches are needed in the area of crisis communication management. The aim of the study is to determine the types of crises that often occur in universities and evaluate the crisis communication efforts in higher education institutions. Crises and crisis communication efforts were evaluated within the framework of media reflections in this study. Content analysis was applied in the classification of crises and responses provided for crises. As a result, the types of crises in Turkish universities were determined as campus safety, actions, protests, loss of confidential information, loss of financial opportunities, loss of key managers and personnel, staff problems, increase of accidents, slander and gossip, unnecessary explanations, rumors, damage to organization and employee reputation, terrorism, workplace violence, corruption, fire and epidemic. It is seen that universities don’t make any communicational effort regarding campus safety, staff problems, increase of accidents, corruption or fire.

    2012-01-01

    Full Text Available Geoffrey Bawa (1919-2003, not well known in our ambience, was Sri Lanka's most influential architect and South Asia's leading guru of unique style, named tropical architecture. The distinction of his work is outstanding aesthetic sensitivity to site and context, especially to peculiar climatic conditions and demands. For his architectural opus he received in 2001 prestigious Aga Khan Award for Architecture, Special Chairman's Award. Although he started to engage in architecture late, in age of 38, soon he became a noted by his inventiveness in forming new canons and prototypes of modern architecture, based on traditional knowledge and perfectly fitted in local surrounding. Bawa created sustainable architecture even before the term started to be used and his masterpieces broke down the barrier between inside and outside space, designing of the interior and landscaping, reducing the building to a series of scenic spaces separated by courtyards and gardens. He is well known by his designs for private villas and hotels, but his portfolio contains public building, as schools and universities, new Sri Lanka's Parliament, sacral, office and industrial structures. Through the presentation of several projects, the paper analyzes his development path and basic characteristics of so called 'monsoon modernism' and special relationship to the bioclimatic conditions of the environment.

    Objectives: To present the clinicopathological experience of Olfactory Neuroblastoma (ONB) with emphasis on histopathological and immunohistochemical features. Methods: A descriptive cross-sectional study was done on 36 cases of ONB, selected by non-probability purposive sampling. Theses cases of ONB were retrieved and reviewed from surgical pathology database of Aga Khan University Hospital reported between January 1993 and March 2015. Results: Tumor size and age of presentation was wide in range without any distinct bimodal distribution. Nasal cavity was most common site along with involvement of paranasal sinuses. More than 50% cases had Kadish stage A. Microscopically, most cases were Grade-1 and majority showed partial or complete lobular architecture. Neurofibrillary matrix was observed in 2/3rd of cases. Among immunohistochemical markers, Neuron Specific Enolase was most frequently expressed. Unusual positive expression of Cytokeratin AE1/AE3 and Cytokeratin CAM5.2 was also seen focally in few cases. Conclusion: The ONB has great variability of histological and clinical presentation, and immunohistochemical markers are useful to differentiate from more common small round blue cell tumours of nasal cavity.

    2014-01-01

    Full Text Available New onset refractory status epilepticus (NORSE is a new entity in medical literature. It has different infectious and noninfectious etiologies showing a devastating impact onto the clinical outcome of patients. Therapy with anaesthetic and antiepileptic agents often fails to improve the condition, unless the primary cause is rectified. Here is presented the case of a young female with a history of depression who after a recent bereavement came to the Emergency Department of Aga Khan University Hospital with complaints of drowsiness that lasted for few hours. Though she had no history of organophosphate poisoning, her physical examination and further investigations were suggestive of the diagnosis. During her hospital stay, she developed refractory status epilepticus. Her seizures did not respond to standard antiepileptic and intravenous anesthetic agents and subsided only after intravenous infusion of atropine for a few days. Organophosphate poisoning is a very common presentation in the developing world and the associated status epilepticus poses a devastating problem for emergency physicians. In patients with suspected organophosphate poisoning with favoring clinical exam findings, the continuation of atropine intravenous infusion can be a safe option to abate seizures.

    Midwives in Pakistan and the South Asian region who complete a diploma program face many challenges for career growth and development. The absence of higher education in professional midwifery in the region has contributed to general non-acceptance and invisibility of midwifery. In response to the interest, Aga Khan University (AKU) developed bachelors program in midwifery based on the Global Standards for Midwifery Education developed by the International Confederation of Midwives (ICM) with the vision to equip midwives to provide full-scope practice, develop confidence to practice midwifery independently, become clinical leaders and contribute to the future of midwifery. The final curriculum had a balance of theory and clinical practice in order to develop a high level of clinical competence that would meet the ICM standards and guidelines. The two year bachelors program is currently in progress. The first cohort of 21 midwives graduated in 2014 and a second cohort was enrolled in 2015. There is a planning for a future graduate program in midwifery to prepare individuals for leadership roles in practice, teaching, maternal-child health provision and policy making through a master's degree in midwifery.

    Mustafa Raoof

    Full Text Available BACKGROUND: Indiscriminate prescription of Benzodiazepines in Pakistan and subsequent availability over-the-counter without prescription is a major public health problem, requiring systematic inquiry through research. Additionally, there is limited data on the awareness and use of Benzodiazepines from developing countries making it impossible to devise meaningful health policies. METHODOLOGY/PRINCIPAL FINDINGS: This was an Observational, Cross-Sectional study. conducted at Aga Khan University. A total of 475 (58.5% males, 41.5% females people visiting a tertiary care hospital were interviewed by means of a structured questionnaire. The results showed that majority of population was aware of one or more Benzodiazepines (80.4% and 30.4% had used them at some point in life. 42.4% of the users had been using it for more than a year. Commonest reason for use was sleep disturbance. Frequency of usage was higher for females, married individuals, educated (>Grade12, high socioeconomic status and housewives. More (59% were prescribed than not and of them most by GP (58.5%. Only 36.5% of them were particularly told about the long-term addiction potential by the use of these drugs. CONCLUSION: Easy availability, access to re-fills without prescription and self prescription compounded with the lack of understanding of abuse potential of benzodiazepines constitutes a significant problem demanding serious consideration from health policy makers.

    Crimean-Congo hemorrhagic fever (CCHF) is endemic in the Baluchistan province, Pakistan. Sporadic outbreaks of CCHF occur throughout the year especially in individuals in contact with infected livestock. Nosocomial transmission remains a risk due to difficulties in the diagnosis of CCHF and limited availability of facilities for the isolation of suspected patients. Rapid diagnosis of CCHF virus infection is required for early management of the disease and to prevent transmission. This study describes the case of a 43-year-old surgeon who contracted CCHF during a surgical procedure in Quetta, Baluchistan and who was transferred to a tertiary care facility at the Aga Khan University Hospital, Karachi within 1 week of contracting the infection. Diagnosis of CCHF was made using a rapid real-time reverse transcription polymerase chain reaction (RT-PCR) assay for CCHF viral RNA. The patient had chronic hepatitis B and hepatitis D infection for which he had previously received a liver transplant. He proceeded to develop classic hemorrhagic manifestations and succumbed to the infection 14 days post-onset of disease. There was no further nosocomial transmission of the CCHF during the hospital treatment of the surgeon. Early diagnosis of CCHF enables rapid engagement of appropriate isolation, barrier nursing and infection control measures thus preventing nosocomial transmission of the virus.

    Full Text Available OBJECTIVE: To study frequency and associated factors for care giving among elderly patients visiting a teaching hospital in Karachi, Pakistan. METHODOLOGY: A cross sectional questionnaire-based study was conducted at the Community Health Centre (CHC, Aga Khan University Hospital (AKUH Karachi, Pakistan from September to November 2009. All individuals, visiting the CHC and aged 65 years or above were interviewed after taking written informed consent. RESULTS: A total of 400 elderly completed the interview. Majority were females, 65-69 years age, More than half of the individuals ie: 227 (85% had received Care Giver experience for assistance and among these 195(72% had care provided by an immediate family member. A large proportion of them stated that their Care Givers managed to provide less than four hours in a day for care giving. Around 37% showed substantial improvement in their relationship with the care givers. About 70% of the respondents stated that the care provided by the Care Giver improved their quality of life. CONCLUSION: Elderly care is provided by majority of the family members resulting in increased satisfaction level, however small number still not satisfied due to unfulfilled need of these older people. This demands that efforts should be made to strengthen the family support by increasing awareness regarding elderly care and arranging support system by the government.

    Objective: Tracheobronchial injuries are defined as injuries involving the trachea and/or bronchi from the level of the cricoid cartilage extending up to the division of the bronchi. We present a case series with most of the tracheobronchial injuries found to be sustained after penetrating trauma.Methods: A retrospective review was performed at the Aga Khan University, Karachi, Pakistan. From January 2004to December 2009, 168 patients with thoracic trauma were treated, of whom 15 were recognized to have major tracheobronchial and pulmonary injuries.Results: The average age was 31 years with most of the patients being male (14:1). Among them,11 patients had penetrating trauma as the main cause of injury, 3 patients had blunt trauma from road traffic accidents, only 1 patient had combined trauma (blunt and penetrating trauma). Eight patients were diagnosed based on radiological findings. All the patients were treated surgically. Lobectomy was the most common intervention performed in 7 patients. The mortality rate was 7% (1 patient). Most patients survived with no sequelae (10 patients) while 5 survived with disability. We found that penetrating trauma was the leading cause of injury in our series. The severity of injury depends upon the weapon causing the trauma. Patients in our series had multiple injuries and required surgical management.Conclusions: Tracheobronchial injuries are rare but potentially life threatening. They require quick diagnosis and management. Diagnosis tends to be difficult since there are no specialised diagnostic modalities available at present.

    This single group cohort study, undertaken at Aga Khan University Hospital, Karachi, from Jan 2012 to September 2013, assessed patients' satisfaction, spectacle independence and visual disturbance after implantation of multifocal IOLs. A total of 39 patients who underwent bilateral cataract surgery with multifocal IOL implantation were included for telephonic interviews. The mean age of participants was 55.5 ± 8.1 years. The mean follow up time was 9.60 ± 3.19 months. The overall satisfaction rate after surgery was found to be 84.6% and there was no statistically significant association of satisfaction with gender, age or education. In all 84.6%, 94.9% and 84.6% people had spectacle independence for far, intermediate and near, respectively. More than half of participants (59%) had some degree of visual disturbance. In this study, multifocal IOL implantation provided high levels of satisfaction and spectacle independence despite notable risk of halo or glare symptoms at night. Therefore, careful patient selection and preoperative counselling regarding possible risks and benefits is recommended.

    Phlebitis and cellulitis are commonly encountered problems in oncology patients receiving chemotherapy through peripherally inserted intravenous catheters. Use of central venous access devices (CVAD) is desirable. We have seen a steady increase in the use of CVADs in our oncology service with frequent use of indwelling ports, particularly during the last 2 years. In this study we have attempted to elucidate advantages of CVAD and compared them to peripheral catheters. This is a retrospective study with chart review of all oncology patients admitted in our oncology service at the Aga Khan University Hospital from March 2003 to March 2005. A survey was also conducted from a randomly selected sample of parents of children with cancer to elicit parental views regarding their choice of a particular catheter. Catheter-related infections were quite common (over 50%) in patients with peripheral lines, resulting in increased costs and prolonged hospitalization. Externalized CVADs were found difficult to care for, carried a risk of being accidentally pulled out or punctured, and were deemed undesirable for older female patients for cosmetic reasons. We found that the internalized CVADs (portacath) were superior to the externalized or peripheral lines and resulted in better patient and family satisfaction. Use of peripheral lines must be gradually phased out of pediatric oncology practice in Pakistan. Indwelling CVADs have become the standard of care internationally and should be considered for most patients in developing countries whenever resources are available.

    Full Text Available Introduction. Mentoring is a recognized form of teaching learning strategy in postgraduate medical education. This paper describes the effectiveness of a formal mentorship program from the residents’ perspective after a year of implementation. Methods. The Aga Khan University Family Medicine Residency Program is the first program in Pakistan to our knowledge to implement formal mentorship for all four years of residency. A mentorship program was developed, implemented, and evaluated a year later using a rating scale. The 10-point Likert scale consisted of questions on academics, clinical work, research, administrative issues, and personal/social issues. Results. The response rate was 95% (. Eighty percent ( were women. Satisfaction level in seeking help was the highest for academics (75%. Residents scored mentorship as low in helping to tackle their personal problems (20%. Barriers reported in rapport building with mentor were time constraints and gender difference. The most useful attributes of the mentor which helped rapport building were accessibility, active listening, support for emotional needs, and trustworthiness. Conclusion. Mentoring has a role in trainees’ personal and professional growth especially when their needs are addressed. The effectiveness of the mentorship program in residency can improve if the residents are allowed to choose their own mentors.

    Purpose: In this study we proposed Adaptive radiotherapy for IMRT patients which will brought an additional dimension to the management of patients with H&N cancer in Aga Khan University Hospital. Methods: In this study 5 Head and Neck (H&N) patients plan where selected, who’s Re-CT were done during the course of their treatment, they were simulated with IMRT technique to learn the consequence of anatomical changes that may occur during the treatment, as they are more dramatic changes can occur as compare to conventional treatment. All the organ at risk were drawn according RTOG guidelines and doses were checked as per NCCN guidelines. Results: The reduction in size of Planning target volume (PTV) is more than 20% in all the cases which leads to 3 to 5 % overdose to normal tissues and Organ at Risk. Conclusion: Through this study we would like to emphasis the importance of Adaptive Radiotherapy practice in all IMRT (H&N) patients, although prospective studies are required with larger sample sizes to address the safety and the clinical effect of such approaches on patient outcome, also one need to develop protocols before implementation of this technique in practice.

  20. Research on universal combinatorial coding.

    2014-01-01

    The conception of universal combinatorial coding is proposed. Relations exist more or less in many coding methods. It means that a kind of universal coding method is objectively existent. It can be a bridge connecting many coding methods. Universal combinatorial coding is lossless and it is based on the combinatorics theory. The combinational and exhaustive property make it closely related with the existing code methods. Universal combinatorial coding does not depend on the probability statistic characteristic of information source, and it has the characteristics across three coding branches. It has analyzed the relationship between the universal combinatorial coding and the variety of coding method and has researched many applications technologies of this coding method. In addition, the efficiency of universal combinatorial coding is analyzed theoretically. The multicharacteristic and multiapplication of universal combinatorial coding are unique in the existing coding methods. Universal combinatorial coding has theoretical research and practical application value.

    This paper explores a research gap at the intersection of university internationalization and university autonomy. A process model of university internationalization is put forward whereby the process of university internationalization is mediated by university internationalization capacity...... and moderated by target country institutional autonomy and globalization; and entry modes, timing and pace, as well as product mix of internationalization define university’s internationalization pattern. A systematic review is conducted to identify empirical studies at this intersection. One of the questions...... this paper is addressing is whether there is a scope for international business theories in explaining university internationalization or in light of recent findings from successes and failures of university internationalization international business theories ought to be revised?...

    2003-01-01

    Recent announcements that the Cosmic Microwave Background (CMB) - the faint remnant of the Big Bang - is polarized have caused a stir among cosmologists. Such polarization has long been predicted but could not be detected, until the recent DASI and WMAP detections. The polarization is a signature of the motion of the primordial seeds that led to the galaxies and large-scale structure of the Universe observed today. Earlier measurements of tiny temperature fluctuations in the CMB have been used to infer the sizes of the primordial seeds. The polarization signature should help to determine the fundamental parameters of cosmology and to explain how large-scale structure arose [Highwire abstract].

    A model is presented for the origin of the large scale structure of the universe and their Mass-Radius scaling law. The physics is conventional, orthodox, but it is used to fashion a highly unorthodox model of the origin of the galaxies, their groups, clusters, super-clusters, and great walls. The scaling law fits the observational results and the model offers new suggestions and predictions. These include a largest, a supreme, cosmic structure, and possible implications for the recently observed pressing cosmological anomalies.

    The cosmos is an awfully big place and there is no better guide to its vast expanse and fascinating nooks and crannies than John Barrow. A professor of mathematical sciences at Cambridge University, Barrow embodies that rare combination of highly polished writer and expert scientist. His deft touch brings together the disparate threads of human knowledge and weaves them into a tapestry as rich and interesting for the expert as it is for the layperson. The Artful Universe Expanded is an updated edition of this popular book first published in 1995. It explores the deeply profound manner in which natural law and the nature of the cosmos have moulded and shaped us, our cultures and the very form of our arts and music-a new type of 'cosmic' anthropology. The main themes Barrow chooses for revealing this new anthropology are the subjects of evolution, the size of things, the heavens and the nature of music. The book is a large, eclectic repository of knowledge often unavailable to the layperson, hidden in esoteric libraries around the world. It rivals The Da Vinci Code for entertainment value and insights, but this time it is Nature's code that is revealed. It is rare indeed to find common threads drawn through topics as diverse as The Beetles, Bach and Beethoven or between Jackson Pollock, the Aztecs, Kant, Picasso, Byzantine mosaics, uranium-235 and the helix nebula. Barrow unerringly binds them together, presenting them in a stimulating, conversational style that belies the amount of time that must have gone into researching this book. Dip into it at random, or read it from cover to cover, but do read it. The Artful Universe Expanded is an entertaining antidote to the oft-lamented pressures to know more and more about less and less and the apparently inexorable march of specialization. On reading this book one can, for a short time at least, hold in one's mind a vision that unifies science, art and culture and glimpse a universal tapestry of great

    We study universal uncertainty relations and present a method called joint probability distribution diagram to improve the majorization bounds constructed independently in [Phys. Rev. Lett. 111, 230401 (2013)] and [J. Phys. A. 46, 272002 (2013)]. The results give rise to state independent uncertainty relations satisfied by any nonnegative Schur-concave functions. On the other hand, a remarkable recent result of entropic uncertainty relation is the direct-sum majorization relation. In this paper, we illustrate our bounds by showing how they provide a complement to that in [Phys. Rev. A. 89, 052115 (2014)]. PMID:27775010

    2003-01-01

    By assuming certain analytic properties of the propagator, it is shown that universal features of the spectral function including threshold enhancement arise if a pole describing a particle at high temperature approaches in the complex energy plane the threshold position of its two-body decay with the variation of T. The case is considered, when one can disregard any other decay processes. The quality of the proposed description is demonstrated by comparing it with the detailed large N solution of the linear sigma model around the pole-threshold coincidence.

In this work, a theoretical framework is proposed in which it is possible to address when and to what extent such semantic communication is possible: such problems can be rigorously addressed by explicitly focusing on the goals of the communication. Under this framework, it is possible to show that for many goals, communication without any common language or background is possible using universal protocols. This work should be accessible to anyone with an undergraduate-level knowled

    Recent measurements of over 1056 confirmed exoplanets reveal details about their masses, compositions, orbital parameters, possible evolutionary histories, and even their atmospheres. These results, though marking just the beginnings of a dramatic new period of exoplanet discovery, suggest that for all practical purposes we are alone in the universe, at least in the sense implied by SETI: extraterrestrial intelligence. This talk will summarize the evidence to date, offer conclusions about the critical importance of increased exoplanet research, and emphasize the need for a renewed appreciation of the rare value of the Earth, its fragile environment, and its inhabitants.

    This book presents a new approach to the subject of cosmology. It fully exploits Einstein's theory of general relativity. It is found that the most general formal expression of the theory replaces the (10-component) tensor formalism with a (16-component) quaternion formalism. This leads to a unified field theory, where one field incorporates gravitation and electromagnetism. The theory predicts an oscillating universe cosmology with a spiral configuration. Dark matter is explained in terms of a sea of particle-antiparticle pairs, each in a particular (derived) ground state. This leads to an ex

We apply the proposed methodology to extract from data the Higgs branching ratios, production cross sections, couplings and to analyse composite H...... as an alternative to the Higgs, and disfavour fits with negative Yukawa couplings. We derive for the first time the SM Higgs boson mass from the measured rates, rather than from the peak positions, obtaining M-h = 124.4 +/- 1.6 GeV....

  6. Models of the universe

    Fischer, Arthur E.

    1996-01-01

    In this paper a theory of models of the universe is proposed. We refer to such models ascosmological models, where a cosmological model is defined as an Einstein-inextendible Einstein spacetime. A cosmological model isabsolute if it is a Lorentz-inextendible Einstein spacetime,predictive if it is globally hyperbolic, andnon-predictive if it is nonglobally-hyperbolic. We discuss several features of these models in the study of cosmology. As an example, any compact Einstein spacetime is always a non-predictive absolute cosmological model, whereas a noncompact complete Einstein spacetime is an absolute cosmological model which may be either predictive or non-predictive. We discuss the important role played by maximal Einstein spacetimes. In particular, we examine the possible proper Lorentz-extensions of such spacetimes, and show that a spatially compact maximal Einstein spacetime is exclusively either a predictive cosmological model or a proper sub-spacetime of a non-predictive cosmological model. Provided that the Strong Cosmic Censorship conjecture is true, a generic spatially compact maximal Einstein spacetime must be a predictive cosmological model. It isconjectured that the Strong Cosmic Censorship conjecture isnot true, and converting a vice to a virtue it is argued that the failure of the Strong Cosmic Censorship conjecture would point to what may be general relativity's greatest prediction of all, namely,that general relativity predicts that general relativity cannot predict the entire history of the universe.

    Over the past few decades, NASA missions have revealed that we live in a Universe that is not a hydrogen-dominated, physicist's paradise, but in a molecular Universe with complex molecules directly interwoven into its fabric. These missions have shown that molecules are an abundant and important component of astronomical objects at all stages of their evolution and that they play a key role in many processes that dominate the structure and evolution of galaxies. Closer to home in our galaxy, the Milky Way, they have revealed a unique and complex organic inventory of regions of star and planet formation that may well represent some of the prebiotic roots to life. Astrobiology emerges from the great interest in understanding astrochemical evolution from simple to complex molecules, especially those with biogenic potential and the roles they may play as primordial seeds in the origin of life on habitable worlds. The first part of this talk will highlight how infrared spectroscopic studies of interstellar space, combined with dedicated laboratory simulations, have revealed the widespread presence of complex organics across deep space. The remainder of the presentation will focus on the evolution of these materials and astrobiology.

  8. Universality of TMD correlators

    Buffing M.G.A.

    2015-01-01

    Full Text Available In a high-energy scattering process with hadrons in the initial state, color is involved. Transverse momentum dependent distribution functions (TMDs describe the quark and gluon distributions in these hadrons in momentum space with the inclusion of transverse directions. Apart from the (anti-quarks and gluons that are involved in the hard scattering process, additional gluon emissions by the hadrons have to be taken into account as well, giving rise to Wilson lines or gauge links. The TMDs involved are sensitive to the process under consideration and hence potentially nonuniversal due to these Wilson line interactions with the hard process; different hard processes give rise to different Wilson line structures. We will show that in practice only a finite number of universal TMDs have to be considered, which come in different linear combinations depending on the hard process under consideration, ensuring a generalized universality. For quarks this gives rise to three Pretzelocity functions, whereas for gluons a richer structure of functions arises.

    We present our study on cosmic opacity, which relates to changes in photon number as photons travel from the source to the observer. Cosmic opacity may be caused by absorption or scattering due to matter in the Universe, or by extragalactic magnetic fields that can turn photons into unobserved particles (e.g., light axions, chameleons, gravitons, Kaluza-Klein modes), and it is crucial to correctly interpret astronomical photometric measurements like type Ia supernovae observations. On the other hand, the expansion rate at different epochs, i.e., the observational Hubble parameter data H (z ), are obtained from differential ageing of passively evolving galaxies or from baryon acoustic oscillations and thus are not affected by cosmic opacity. In this work, we first construct opacity-free luminosity distances from H (z ) determinations, taking into consideration correlations between different redshifts for our error analysis. Moreover, we let the light-curve fitting parameters, accounting for distance estimation in type Ia supernovae observations, free to ensure that our analysis is authentically cosmological-model independent and gives a robust result. Any nonzero residuals between these two kinds of luminosity distances can be deemed as an indication of the existence of cosmic opacity. While a transparent Universe is currently consistent with the data, our results show that strong constraints on opacity (and consequently on physical mechanisms that could cause it) can be obtained in a cosmological-model-independent fashion.

    We use the directed networks between articles of 24 Wikipedia language editions for producing the wikipedia ranking of world Universities (WRWU) using PageRank, 2DRank and CheiRank algorithms. This approach allows to incorporate various cultural views on world universities using the mathematical statistical analysis independent of cultural preferences. The Wikipedia ranking of top 100 universities provides about 60% overlap with the Shanghai university ranking demonstrating the reliable features of this approach. At the same time WRWU incorporates all knowledge accumulated at 24 Wikipedia editions giving stronger highlights for historically important universities leading to a different estimation of efficiency of world countries in university education. The historical development of university ranking is analyzed during ten centuries of their history.

    Wardle, M; Wardle, Mark Walker & Mark

    1999-01-01

    Modelling of Extreme Scattering Events suggests that the Galaxy's dark matter is an undetected population of cold, AU-sized, planetary-mass gas clouds. None of the direct observational constraints on this picture -- thermal/non-thermal emission, extinction and lensing -- are problematic. The theoretical situation is less comfortable, but still satisfactory. Galactic clouds can survive in their current condition for billions of years, but we do not have a firm description for either their origin or their evolution to the present epoch. We hypothesise that the proto-clouds formed during the quark-hadron phase transition, thereby introducing the inhomogeneity necessary for compatibility with light element nucleosynthesis in a purely baryonic universe. We outline the prospects for directly detecting the inferred cloud population. The most promising signatures are cosmic-ray-induced H-alpha emission from clouds in the solar neighbourhood, optical flashes arising from cloud-cloud collisions, ultraviolet extinction,...

    We consider a Hubble expansion law modified in the infra-red by distance-dependent terms, and attempt to enforce homogeneity upon it. As a warm-up, we re-derive the basic kinematics of a Friedman Robertson Walker universe without using standard general relativistic tools: we describe the expansion with a `Hubble velocity field' rather than with a four dimensional metric. Then we extend this analysis to the modified Hubble expansion and impose a transformation for velocities that makes it identical for all comoving observers, and therefore homogeneous. We derive the modified equation for light ray trajectories and other geometrical properties that are incompatible with the general relativistic description. We speculate that this extended framework could help addressing cosmological problems which are normally explained with accelerating expansions.

    2005-01-01

    We investigate the point-parity and mirror-parity handedness of the large angle anisotropy in the cosmic microwave background (CMB). In particular we consider whether the observed low CMB quadrupole could more generally signal odd point-parity, i.e. suppression of even multipoles. Even though this feature is ``visually'' present in most renditions of the WMAP dataset we find that it never supports parity preference beyond the meagre 95% confidence level. This is fortunate as point parity handedness implies almost certainly a high level of galactic contamination. Mirror reflection parity, on the contrary, is related to the emergence of a preferred axis, defining the symmetry plane. We use this technique to make contact with recent claims for an anisotropic Universe, showing that the detected preferred axis is associated with positive (even) mirror parity. This feature may be an important clue in identifying the culprit for this unexpected signal.

    There are currently over 900 facilities in over 170 countries which fall under International Atomic Energy Agency (IAEA) safeguards. As additional nations look to purse civilian nuclear programs or to expand infrastructure already in place, the number of reactors and accompanying facilities as well as the quantity of material has greatly increased. Due to the breadth of the threat and the burden placed on the IAEA as nuclear applications expand, it has become increasingly important that safeguards professionals have a strong understanding of both the technical and political aspects of nonproliferation starting early in their career. To begin overcoming this challenge, Idaho National Laboratory, has partnered with local universities to deliver a graduate level nuclear engineering course that covers both aspects of the field with a focus on safeguards applications. To date over 60 students across multiple disciplines have participated in this course with many deciding to transition into a nonproliferation area of focus in both their academic and professional careers.

  18. Universal quantum sorter

    2015-01-01

    Measuring the state of a quantum system is a fundamental process in quantum mechanics and plays an essential role in quantum information and quantum technologies. One method to measure a quantum observable is to sort the system in different spatial modes according to the measured value, followed by single-particle detectors on each mode. Examples of quantum sorters are polarizing beam-splitters (PBS) -- which direct photons according to their polarization -- and Stern-Gerlach devices. Here we propose a general scheme to sort a quantum system according to the value of any $d$-dimensional degree of freedom, such as spin, orbital angular momentum (OAM), wavelength etc. Our scheme is universal, works at single-particle level and has a theoretical efficiency of 100%. As an application we design an efficient OAM sorter consisting of a single multi-path interferometer which is suitable for a photonic chip implementation.

  1. The Politics of Universalism

    Simonsen, Karen-Margrethe

    2013-01-01

    This article investigates the political function of human rights in the 16th Century in Spain just after the conquest of America. It claims that the study of this period of early globalization is relevant for the understanding of the function of human rights discourses to day, at the ‘end......’ of globalization. Historically speaking, human rights are closely connected with globalization, but at the same time, they raise a question about the foundation of globalization: is there a universal community or only economic and political power-relations? The article argues that the political use of human rights...... discourses is split down the middle: it serves both as a critique of power and as an extension of power, and the disclosure of this split helps us understand the inner politics of human rights. The article discusses the trial in Valladolid in 1550 when the rights of the barbarian Indians of America were put...

    Although there are a number of visualization systems to choose from when analyzing data, only a few of these allow for the integration of other visualization and analysis techniques. There are even fewer visualization toolkits and frameworks from which one can develop ones own visualization applications. Even within the research community, scientists either use what they can from the available tools or start from scratch to define a program in which they are able to develop new or modified visualization techniques and analysis algorithms. Presented here is a new general-purpose platform for constructing numerous visualization and analysis applications. The focus of this system is the design and experimentation of new techniques, and where the sharing of and integration with other tools becomes second nature. Moreover, this platform supports multiple large data sets, and the recording and visualizing of user sessions. Here we introduce the Universal Visualization Platform (UVP) as a modern data visualization and analysis system.

  3. Universal Limit on Communication

    CERN Document Server

    Bousso, Raphael

    2016-01-01

    I derive a universal upper bound on the capacity of any communication channel between two distant systems. The Holevo quantity, and hence the mutual information, is at most of order $E \\Delta t / \\hbar$, where $E$ the average energy of the signal, and $\\Delta t$ is the amount of time for which detectors operate. The bound does not depend on the size or mass of the emitting and receiving systems, nor on the nature of the signal. No restrictions on preparing and processing the signal are imposed. As an example, I consider the encoding of information in the transverse or angular position of a signal emitted and received by systems of arbitrarily large cross-section. In the limit of a large message space, quantum effects become important even if individual signals are classical, and the bound is upheld.

    The evolution of human languages is driven both by primitive biases present in the human sensorimotor systems and by cultural transmission among speakers. However, whether the design of the language faculty is further shaped by linguistic biological biases remains controversial. To address this question, we used near-infrared spectroscopy to examine whether the brain activity of neonates is sensitive to a putatively universal phonological constraint. Across languages, syllables like blif are preferred to both lbif and bdif. Newborn infants (2-5 d old) listening to these three types of syllables displayed distinct hemodynamic responses in temporal-perisylvian areas of their left hemisphere. Moreover, the oxyhemoglobin concentration changes elicited by a syllable type mirrored both the degree of its preference across languages and behavioral linguistic preferences documented experimentally in adulthood. These findings suggest that humans possess early, experience-independent, linguistic biases concerning syllable structure that shape language perception and acquisition.

    2012-12-01

    The idea that space is not Euclidean by necessity, and that there are other kinds of "curved" spaces, diffused slowly to the physical and astronomical sciences. Until Einstein's general theory of relativity, only a handful of astronomers contemplated a connection between non-Euclidean geometry and real space. One of them, the German astrophysicist Johann Carl Friedrich Zöllner (1834-1882), suggested in 1872 a remarkable cosmological model describing a finite universe in closed space. I examine Zöllner's little-known contribution to cosmology and also his even more unorthodox speculations of a four-dimensional space including both physical and spiritual phenomena. I provide an overview of Zöllner's scientific work, of his status in the German scientific community, and of the controversies caused by his polemical style of science. Zöllner's cosmology was effectively forgotten, but there is no reason why it should remain an unwritten chapter in the history of science.

    An alien invasion of CERN? Is there life elsewhere in the Universe? Are we alone? These questions have always fascinated humanity and for more than 30 years, physicists, biologists, chemists, cosmologists and astronomers have worked tirelessly to answer these questions. Yet just this past week at CERN students from all over Europe came to present their ideas on the subject and listen to the latest on extraterrestrial life from some of the world's most prestigious researchers. Students participating in the programme were encouraged to present their views on extraterrestrial life creatively and boy did they! The team from Portugal ran performances of Greek Theatre, the team from Hungary created a board game, while the team from Belgium recited poetry questioning the existence of extraterrestrials. But all was not light hearted, there were touching presentations of violin and piano by the French team and a very thought provoking theatre performance by the German team contrasting the search for extraterrestrial...

    The Virtual Hybridization approach predicts the most probable hybridization sites across a target nucleic acid of known sequence, including both perfect and mismatched pairings. Potential hybridization sites, having a user-defined minimum number of bases that are paired with the oligonucleotide probe, are first identified. Then free energy values are evaluated for each potential hybridization site, and if it has a calculated free energy of equal or higher negative value than a user-defined free energy cut-off value, it is considered as a site of high probability of hybridization. The Universal Fingerprinting Chip Applications Server contains the software for visualizing predicted hybridization patterns, which yields a simulated hybridization fingerprint that can be compared with experimentally derived fingerprints or with a virtual fingerprint arising from a different sample.

    Fred Hoyle was a Yorkshire truant who became the voice of British astronomy. For fifty years, he spoke out for astronomy in the newspapers, on government committees, at scientific meetings, in popular books and on the radio. He devised a never-ending history of the universe, and worked out how the elements were made. He founded a prestigious institute for theoretical astronomy and built a giant telescope, and if it rained on his summer holiday, he sat in his caravan and wrote science fiction novels for his legions of fans around the world. Fred Hoyle also claimed that diseases fall from the sky, that the big bang never happened, and that the Astronomer Royal should be abolished. When the outspoken Fred Hoyle spoke out for astronomy, some astronomers really wished he had kept his mouth shut. This book tells the behind-the-scenes story of Hoyle's widely acclaimed and deeply controversial role in the ideas, organization and public face of astronomy in post-war Britain. It chronicles the triumphs, acrimony, jealousies, rewards and bitter feuds of a field in turmoil, and meets the astronomers, contemplating cosmic questions, keeping secrets, losing their tempers, winkling information out of distant stars and, over tea on the lawn, discussing the finer points of libel law. Fred Hoyle's Universe draws on previously confidential government documents, recently released personal correspondence and interviews with Hoyle's friends, colleagues and critics, as well as with Hoyle himself, to bring you the man, the science, and the scandal behind the genial and genteel facade of the most exciting period in the history of astronomy.

    Full Text Available According to Garcia Canclini (1990 there is the assumption that Colombia is a hybrid society. Upon this standpoint, and within a traditional higher education structure characterized by being fundamentally conventional or campus based, the Open University Center of the Pontificia Universidad Javeriana was created as an education program that breaks with every traditional scheme, which in turn, encourages a new learning pattern. The Open University Center emerges as a "social response" focused on the "here and now" of today's society in Colombia.The Javeriana University (a hybrid university can be placed in this context as well as the Open University Center, as a part of it. Since its creation, through its programs this center offers education to the most vulnerable of Colombia's population, contributing to raise their quality of life.In this article, the authors outline the Open University Center's place in the University's context: its historical development and its structure concerning students, programs, regulations, infrastructure and technological equipment. They also identify the implications and relationships of the traditional education proper of the Pontificia Universidad Javeriana, as well as the projection and contributions of the Open University Center to the University's future in the pedagogical order of distance education towards virtual education.

    Today many universities have the vision to become a research university, including in Indonesia. It is based on the desire to play a role in advancing science for the benefit of humanity as well as to enhance the university reputation at the international level. However, in the case of Indonesia, it can only be done by several universities, given the large number of universities with very different capabilities. In addition, another problem is human resources, infrastructure, and research funding. Various targets indicator used to determine its success include the number of publications, patents and industrial products. There is an urgent need to improve all factors that can accelerate the increase in research in Indonesia universities, and has been started by the policy of the current government.

    2016-01-01

    This book challenges traditional approach to university autonomy which is based on four pillars: organisational, financial, human resource, and academic. The main thesis is that a fuller understanding of university autonomy can only be obtained through a more holistic view of the complex inter......-relationships between stakeholders and policies which can reinforce and equally pull in opposite directions. The holistic view is expressed in a model of institutional university autonomy that brings together the traditional basic four pillars of autonomy, and five interfaces: government–university; university–university...... staff; academic staff–students; university–business; and university–internationalisation. This model is explored through international case studies that give new insights and reinforce our understanding that the issues relating to institutional university autonomy are complex, interactive and genuinely...

  13. A Small Universal Petri Net

    2013-09-01

    Full Text Available A universal deterministic inhibitor Petri net with 14 places, 29 transitions and 138 arcs was constructed via simulation of Neary and Woods' weakly universal Turing machine with 2 states and 4 symbols; the total time complexity is exponential in the running time of their weak machine. To simulate the blank words of the weakly universal Turing machine, a couple of dedicated transitions insert their codes when reaching edges of the working zone. To complete a chain of a given Petri net encoding to be executed by the universal Petri net, a translation of a bi-tag system into a Turing machine was constructed. The constructed Petri net is universal in the standard sense; a weaker form of universality for Petri nets was not introduced in this work.

  14. Is the Universe logotropic?

    Science.gov (United States)

    Chavanis, Pierre-Henri

    2015-07-01

    We consider the possibility that the universe is made of a single dark fluid described by a logotropic equation of state P = A ln( ρ/ρ*, where ρ is the rest-mass density, ρ * is a reference density, and A is the logotropic temperature. The energy density ɛ is the sum of two terms: a rest-mass energy term ρ c 2 that mimics dark matter and an internal energy term u( ρ) = - P( ρ) - A that mimics dark energy. This decomposition leads to a natural, and physical, unification of dark matter and dark energy, and elucidates their mysterious nature. In the early universe, the rest-mass energy dominates and the dark fluid behaves as pressureless dark matter ( P ≃ 0, ɛ ∝ a -3. In the late universe, the internal energy dominates and the dark fluid behaves as dark energy ( P ˜ - ɛ, ɛ ∝ ln a. The logotropic model depends on a single parameter B = A / ρ Λ c 2 (dimensionless logotropic temperature), where ρ Λ = 6.72 × 10-24 g m-3 is the cosmological density. For B = 0, we recover the ΛCDM model with a different justification. For B > 0, we can describe deviations from the ΛCDM model. Using cosmological constraints, we find that 0 ≤ B ≤ 0.09425. We consider the possibility that dark matter halos are described by the same logotropic equation of state. When B > 0, pressure gradients prevent gravitational collapse and provide halo density cores instead of cuspy density profiles, in agreement with the observations. The universal rotation curve of logotropic dark matter halos is consistent with the observational Burkert profile (Burkert, Astrophys. J. 447, L25 (1995)) up to the halo radius. It decreases as r -1 at large distances, similarly to the profile of dark matter halos close to the core radius (Burkert, arXiv:1501.06604). Interestingly, if we assume that all the dark matter halos have the same logotropic temperature B, we find that their surface density Σ 0 = ρ0 r h is constant. This result is in agreement with the observations (Donato et al., Mon

    The boundary conditions to be imposed on the quantum state of the whole multiverse could be such that the universes would be created in entangled pairs. Then, interuniversal entanglement would provide us with a vacuum energy for each single universe that might be fitted with observational data, making testable not only the multiverse proposal but also the boundary conditions of the multiverse. Furthermore, the second law of the entanglement thermodynamics would enhance the expansion of the single universes.

    We investigate the behaviour of exact closed bouncing Friedmann universes in theories with varying constants. We show that the simplest BSBM varying alpha theory leads to a bouncing universe. The value of alpha increases monotonically, remaining approximately constant during most of each cycle, but increasing significantly around each bounce. When dissipation is introduced we show that in each new cycle the universe expands for longer and to a larger size. We find a similar effect for closed bouncing universes in Brans-Dicke theory, where G also varies monotonically in time from cycle to cycle. Similar behaviour occurs also in varying speed of light theories.

    Full Text Available The dramatic expansion of Taiwan universities/colleges from about 100 to 160 from the late 1980s has encountered problems due to social and global changes. What should Taiwan universities move toward and how? This research relies on secondary data to explore the issues Taiwan universities currently face—a low birth rate and global competition. The decreasing number of incoming students will result in a lower registration rate and less tuition revenue, which will make some universities struggle to survive. Hence, government policies, proposed by the Ministry of Education, have been implemented to assist Taiwan universities to adjust to external changes. The Innovative Transformation Policy, adopted in 2015, consists of strategies for university–industry cooperation, university mergers, university closures, and a re-shaping of the university paradigm. This policy has begun to be implemented and its initial outcome will be continually evaluated. In accordance with the Innovative Transformation Policy, this study encourages Taiwan universities to improve governance, set prominent unique characteristics of development, and enhance global competitiveness.

    The philosophy of my life is to keep encouraging children to think beyond they could achieve easily. I understand children are adaptive to change and take things with an open mind. They are ready to experiment with new things and dare to dream big. I am fortunate to being a teacher by profession and thus I always attempt experimenting, observing, and participating with other children and adults. Children learn through play. From birth, children are active participants in building their own understanding. Teachers prepare the environment to help each child build on what they already know. It is such a great pleasure to observe every young kid that becomes excited and curious to know when we show them the Universe pictures and tell them about the strange objects in our Universe. So my aim is to keep them ignited by doing different activities throughout the year related to Space. I am always a firm believer of: Creativity is the key to success in the future, and primary education is where teachers can bring creativity in children at that level. One of my main ways of teaching is to conduct various presentations on The Solar System and beyond and debates on Space explorations. A Planet making project is one of the all-time favorite project for my students where they dare to dream to fly in the universe, and with their imagination, kids make different celestial objects and present them. To inculcate scientific attitude I arrange film screening, simulation exercises and quizzes on various topics of astronomy. Every year we celebrate World Space Week 4th to 10th of Oct. The motivation among all came through different hands-on activities like-painting, slogan competition, topics related to space, poetry and essay writing on various topics related to astronomy, assembly presentations in school. I am indeed overwhelmed when I started the very special Space and Astronomy club where young toddlers are involved in different activities like a star gazing program, conducting

  1. Postmodernity and the university

    Directory of Open Access Journals (Sweden)

    Peter Scott

    2012-09-01

    Full Text Available The utility of post-modernism as an interpretative framework for understanding the development of contemporary higher education systems is sharply contested. Critics argue that post-modernism is, at best, a set of ideas in aesthetics, literature and critical theory with limited relevance outside these domains and, at worst, a passing intellectual fashion that is now out-of-date. However, post-modernity —or, as some would prefer, late modernity or ‘fluid’ modernity — is perhaps a more useful idea. In 21stcentury society there are a number of trends, some structural such as the growth of a knowledge-based economy and development of new patterns of knowledge production; and some conceptual such as the reconfiguration of time and space and the recognition of ‘difference’ (and risk? as key factor in the constitution of social life (and individual identity, which have a direct impact on the university. This impact is felt in two ways — first, the university is a primary engine of these transformations. Secondly, the university is shaped by these transformations (both normatively and cognitively in terms of teaching and research and structurally in terms of its organisational characteristics, governance and managementLa utilidad del postmodernismo como marco interpretativo para comprender el desarrollo de los sistemas contemporáneos de educación superior ha sido severamente contestada. Los críticos argumentan que el postmodernismo es, como mucho, un conjunto de ideas en los ámbitos de la estética, literatura y teoría crítica con relevancia limitada fuera de esos campos y, a lo peor, una moda intelectual pasajera que actualmente está caducada. No obstante, la postmodernidad —o, como algunos preferirían, la modernidad tardía o modernidad «fluida»— es quizá una idea más útil. En la sociedad del siglo XXI hay un cúmulo de tendencias, algunas estructurales, como el crecimiento de la economía basada en el conocimiento y el

  2. Transparency of University Rankings in the Effective Management of University

    Full Text Available University rankings are extremely important not only for future student, but also for universities themselves. They have a large impact on the institutions of higher education. A lot of universities believe, that rankings help them to maintain and create a reputation. Ranking systems function as some kind of fashion arena, where universities make comparisons between themselves. Universities want to improve their position in published classifications, so very often they try to change their policy and strategy. They also try to influence the ranking indicators, for example by hiring Nobel Prize winners. Therefore, there is an increasing need for reliable and transparent information about schools. However universities need not only statistical data, but also the tools, which will be useful in their comparisons and evaluations. The article presents the possibility of using one of the methods of graphic presentation of multidimensional empirical data structure, so called RGM, proposed by M. Rybaczuk. Thanks to this method universities could easily compare one another. They also could identify the fields of their activities, in which they are able to be better. The proposed way of graphical presentation of the universities could be a useful addition to traditional rankings, which just show us a lists of schools from the best to the worst.

    Full Text Available In the face of global competition and rising challenges that higher education institutions (HEIs meet, it is imperative to increase innovativeness and efficiency of their management. Benchmarking can be the appropriate tool to search for a point of reference necessary to assess institution’s competitive position and learn from the best in order to improve. The primary purpose of the paper is to present in-depth analysis of benchmarking application in HEIs worldwide. The study involves indicating premises of using benchmarking in HEIs. It also contains detailed examination of types, approaches and scope of benchmarking initiatives. The thorough insight of benchmarking applications enabled developing classification of benchmarking undertakings in HEIs. The paper includes review of the most recent benchmarking projects and relating them to the classification according to the elaborated criteria (geographical range, scope, type of data, subject, support and continuity. The presented examples were chosen in order to exemplify different approaches to benchmarking in higher education setting. The study was performed on the basis of the published reports from benchmarking projects, scientific literature and the experience of the author from the active participation in benchmarking projects. The paper concludes with recommendations for university managers undertaking benchmarking, derived on the basis of the conducted analysis.

CAST searches for solar axions pointing a recycled LHC magnet towards the Sun, and, it provides new results since 2002. Its working principle might well be already at work in outer space, asking for an alternative, though exotic, point of view for certain myst...

  8. A Self Organizing Universe

    Wagner, Orvin E.

    2001-05-01

    First Feynman and Wheeler suggested in-out waves associated with elementary particles. Quantum field theory has waves propagating backward in time producing standing waves. The math suggests that the sun also produces its own in-out waves which spaced and now stabilize the planets. The same is true for the gaseous planets with their sattelites. I propose two postulates (suggested by my work). (1) Longitudinal waves are produced by electromagnetic sources. These waves become standing waves because space(or the vacuum)responds with an automatic return wave related to the inertial nature of space.(2)Larger sources such as the sun excite smaller sources such as the planets with successively smaller sources producing shorter and shorter wavelengths at lower and lower power. The hierarchical nature is suggested by 1/f phenomena. The standing waves from larger sources produce the organizing forces for galaxy and star formation as well as the repeating structures of the universe. The wave effects were first found in plant organization and then it was observed that the waves are everywhere. See the Wagner web site.

  9. Universal Sparse Modeling

    Ramirez, Ignacio

    2010-01-01

    Sparse data models, where data is assumed to be well represented as a linear combination of a few elements from a dictionary, have gained considerable attention in recent years, and their use has led to state-of-the-art results in many signal and image processing tasks. It is now well understood that the choice of the sparsity regularization term is critical in the success of such models. In this work, we use tools from information theory, and in particular universal coding theory, to propose a framework for designing sparsity regularization terms which have several theoretical and practical advantages when compared to the more standard l0 or l1 ones, and which lead to improved coding performance and accuracy in reconstruction and classification tasks. We also report on further improvements obtained by imposing low mutual coherence and Gram matrix norm on the corresponding learned dictionaries. The presentation of the framework and theoretical foundations is complemented with examples in image denoising and c...

    Full Text Available Background. Bevacizumab (BEV, a humanized immunoglobulin G1 monoclonal antibody that inhibits VEGF has demonstrated activity against recurrent high-grade gliomas (HGG in phase II clinical trials. Patients and Methods. Data were collected from patients with recurrent HGG who initiated treatment with BEV outside a clinical trial protocol at two Belgian university hospitals. Results. 19 patients (11 M/8 F were administered a total of 138 cycles of BEV (median 4, range 1–31. Tumor response assessment by MRI was available for 15 patients; 2 complete responses and 3 partial responses for an objective response rate of 26% for the intent to treat population were observed on gadolinium-enhanced T1-weighted images; significant regressions on T2/FLAIR were documented in 10 out of 15 patients (67%. A reduced uptake on PET was documented in 3 out of 4 evaluable patients. The six-month progression-free survival was 21% (95% CI 2.7–39.5. Two patients had an ongoing tumor response and remained free from progression after 12 months of BEV treatment. Conclusions. The activity and tolerability of BEV were comparable to results from previous prospective phase II trials. Reduced uptake on PET suggests a metabolic response in addition to an antiangiogenic effect in some cases with favorable clinical outcome.

  11. Inflation, Universality and Attractors

    Scalisi, Marco

    2016-01-01

    In this PhD thesis, we investigate generic features of inflation which are strictly related to fundamental aspects of UV-physics scenarios, such as string theory or supergravity. After a short introduction to standard and inflationary cosmology, we present our research findings. On the one hand, we show that focusing on universality properties of inflation can yield surprisingly stringent bounds on its dynamics. This approach allows us to identify the regime where the inflationary field range is uniquely determined by both the tensor-to-scalar ratio and the spectral index. Then, we derive a novel field-range bound, which is two orders of magnitude stronger than the original one derived by Lyth. On the other hand, we discuss the embedding of inflation in supergravity and prove that non-trivial hyperbolic K\\"ahler geometries induce an attractor for the inflationary observables: the spectral tilt tends automatically to the center of the Planck dome whereas the amount of primordial gravitational waves is directly...

  12. The Holographic Universe

    CERN Document Server

    Luminet, Jean-Pierre

    2016-01-01

    I give a critical review of the holographic hypothesis, which posits that a universe with gravity can be described by a quantum field theory in fewer dimensions. I first recall how the idea originated from considerations on black hole thermodynamics and the so-called information paradox that arises when Hawking radiation is taken into account. String Quantum Gravity tried to solve the puzzle using the AdS/CFT correspondence, according to which a black hole in a 5-D anti-de Sitter space is like a flat 4-D field of particles and radiation. Although such an interesting holographic property, also called gauge/gravity duality, has never been proved rigorously, it has impulsed a number of research programs in fields as diverse as nuclear physics, condensed matter physics, general relativity and cosmology. I finally discuss the pros and cons of the holographic conjecture, and emphasizes the key role played by black holes for understanding quantum gravity and possible dualities between distant fields of theoretical p...

  13. Universal mechatronics coordinator

    Science.gov (United States)

    Muir, Patrick F.

    1999-11-01

    Mechatronic systems incorporate multiple actuators and sensor which must be properly coordinated to achieve the desired system functionality. Many mechatronic systems are designed as one-of-a-kind custom projects without consideration for facilitating future system or alterations and extensions to the current syste. Thus, subsequent changes to the system are slow, different, and costly. It has become apparent that manufacturing processes, and thus the mechatronics which embody them, need to be agile in order to more quickly and easily respond to changing customer demands or market pressures. To achieve agility, both the hardware and software of the system need to be designed such that the creation of new system and the alteration and extension of current system is fast and easy. This paper describes the design of a Universal Mechatronics Coordinator (UMC) which facilitates agile setup and changeover of coordination software for mechatronic systems. The UMC is capable of sequencing continuous and discrete actions that are programmed as stimulus-response pairs, as state machines, or a combination of the two. It facilitates the modular, reusable programing of continuous actions such as servo control algorithms, data collection code, and safety checking routines; and discrete actions such as reporting achieved states, and turning on/off binary devices. The UMC has been applied to the control of a z- theta assembly robot for the Minifactory project and is applicable to a spectrum of widely differing mechatronic systems.

  14. Hydrogen fuel - Universal energy

    Prince, A. G.; Burg, J. A.

    The technology for the production, storage, transmission, and consumption of hydrogen as a fuel is surveyed, with the physical and chemical properties of hydrogen examined as they affect its use as a fuel. Sources of hydrogen production are described including synthesis from coal or natural gas, biomass conversion, thermochemical decomposition of water, and electrolysis of water, of these only electrolysis is considered economicially and technologically feasible in the near future. Methods of production of the large quantities of electricity required for the electrolysis of sea water are explored: fossil fuels, hydroelectric plants, nuclear fission, solar energy, wind power, geothermal energy, tidal power, wave motion, electrochemical concentration cells, and finally ocean thermal energy conversion (OTEC). The wind power and OTEC are considered in detail as the most feasible approaches. Techniques for transmission (by railcar or pipeline), storage (as liquid in underwater or underground tanks, as granular metal hydride, or as cryogenic liquid), and consumption (in fuel cells in conventional power plants, for home usage, for industrial furnaces, and for cars and aircraft) are analyzed. The safety problems of hydrogen as a universal fuel are discussed, noting that they are no greater than those for conventional fuels.

    Full Text Available Technological development has changed the media and formats for recording information, as well as the methods for their collection, preservation, reproduction and use. After six and a half centuries since the invention of printing press, electronic publications on Internet represent a revolutionary break-through in communication and data transmission. The new format has changed the publication to the extent that the library science should re-define the topic of its research, and re-consider the methods and procedures for its treatment. Consequently, the library science should refer to the underlying terminological and typological research, and re-define the subject of bibliographic processing and determine the elements for the subject’s identification. The new technological platform of electronic publications opens a range of possibilities, which make the significance and value of the established methods of knowledge management very relative, and thus also the basis of the library science and its “raisson d’ętre”. No cultural value is attached to electronic publications due to their specific characteristics, as it has been attached to a book in our civilization. Therefore, collection and long-term preservation of this material is not problematic only from the technological but also from the sociological aspect. By dealing with electronic media, library theory and practice finally step from the area of the known laws of the Gutenberg universe into the new space, where the new working rules will have to be established.

  16. Water in the Universe

    2011-01-01

    Due to its specific chemical and physical properties, water is essential for life on Earth. And it is assumed that this would be the case for extraterrestrial life as well. Therefore it is important to investigate where water can be found in the Universe. Although there are places that are completely dry, places where the last rainfall happened probably several 100 million years ago, surprisingly this substance is quite omnipresent. In the outer solar system the large satellites of Jupiter and Saturn are covered by a thick layer of ice that could be hiding a liquid ocean below. This of course brings up the question of whether the recently detected extrasolar planets could have some water on their surfaces and how we can detect this. Water molecules are also found in interstellar gas and dust clouds. This book begins with an introductory chapter reviewing the physical and chemical properties of water. Then it illuminates the apparent connection between water and life. This is followed by chapters dealing with ...

  17. Universities and Patent Demands.

    Cordova, Andrew K; Feldman, Robin

    2015-11-01

    Research universities have made enormous contributions to the field of medicine and the treatment of human disease. Alone or in collaboration with pharmaceutical companies, academic researchers have added to the store of knowledge that has led to numerous life science breakthroughs. A new chapter may be opening for academic researchers, however, that could lead to a darker tale. 'The mouse that trolled: the long and tortuous history of a gene mutation patent that became an expensive impediment to Alzheimer's research, by Bubela et al., chronicles one such tale.' The authors do an excellent job of bringing to life the twisting saga that engulfed numerous academic and non-profit Alzheimer's researchers over many years. The authors note that the story is an outlier, but sadly, that may not be the case. There are increasing signs that academic researchers and their institutions are being caught up in the rush for gold that is accompanying the proliferation of the non-practicing entity business model. As I have noted before, academic institutions have a dual role, as keepers of the academic flame and guardians of the public monies entrusted to them through state and federal research funding. The specter of taxpayer money being used, not to advance research and for the betterment of society, but as part of schemes to extract money from productive companies may not sit well with voters, and ultimately, with legislators. In that case, researchers and institutions themselves may have much to lose.

    Science.gov (United States)

    Zhang, Tianxi

    2014-06-01

    The black hole universe model is a multiverse model of cosmology recently developed by the speaker. According to this new model, our universe is a fully grown extremely supermassive black hole, which originated from a hot star-like black hole with several solar masses, and gradually grew up from a supermassive black hole with million to billion solar masses to the present state with trillion-trillion solar masses by accreting ambient matter or merging with other black holes. The entire space is structured with infinite layers or universes hierarchically. The innermost three layers include the universe that we live, the inside star-like and supermassive black holes called child universes, and the outside space called mother universe. The outermost layer is infinite in mass, radius, and entropy without an edge and limits to zero for both the matter density and absolute temperature. All layers are governed by the same physics and tend to expand physically in one direction (outward or the direction of increasing entropy). The expansion of a black hole universe decreases its density and temperature but does not alter the laws of physics. The black hole universe evolves iteratively and endlessly without a beginning. When one universe expands out, a new similar one is formed from inside star-like and supermassive black holes. In each of iterations, elements are resynthesized, matter is reconfigurated, and the universe is renewed rather than a simple repeat. The black hole universe is consistent with the Mach principle, observations, and Einsteinian general relativity. It has only one postulate but is able to explain all phenomena occurred in the universe with well-developed physics. The black hole universe does not need dark energy for acceleration and an inflation epoch for flatness, and thus has a devastating impact on the big bang model. In this talk, I will present how this new cosmological model explains the various aspects of the universe, including the origin

  3. Closed-universe recollapse conjecture

    Energy Technology Data Exchange (ETDEWEB)

    Barrow, J.D.; Galloway, G.J.; Tipler, F.J.

    1986-12-15

    It is widely believed that all expanding S/sup 3/ closed universes that satisfy the standard energy conditions recollapse to a second singularity. It is shown that this is false even for Friedmann universes: an ever-expanding S/sup 3/ Friedmann universe is constructed in which the matter tensor satisfies the strong, weak and dominant energy conditions and the generic condition. A general recollapse theorem for Friedmann universes is proved if the positive pressure criterion, dominant enery condition and matter regularity condition hold, then an S/sup 3/ Friedmann universe must recollapse. It is shown that all known vacuum solutions with Cauchy surface topology S/sup 3/ or S/sup 2/XS/sup 1/ recollapse, and we conjecture that this is a property of all vacuum solutions of Einstein's equations with such Cauchy surfaces.

  4. Cognitive biases and language universals

    CERN Document Server

    Baronchelli, Andrea; Puglisi, Andrea

    2013-01-01

    Language universals have been longly attributed to an innate Universal Grammar. An alternative explanation states that linguistic universals emerged independently in every language in response to shared cognitive, though non language-specific, biases. A computational model has recently shown how this could be the case, focusing on the paradigmatic example of the universal properties of color naming patterns, and producing results in accurate agreement with the experimental data. Here we investigate thoroughly the role of a cognitive bias in the framework of this model. We study how, and to what extent, the structure of the bias can influence the corresponding linguistic universal patterns. We show also that the cultural history of a group of speakers introduces population-specific constraints that act against the uniforming pressure of the cognitive bias, and we clarify the interplay between these two forces. We believe that our simulations can help to shed light on the possible mechanisms at work in the evol...

  5. A Model of Nonsingular Universe

    Directory of Open Access Journals (Sweden)

    Changjun Gao

    2012-07-01

    Full Text Available In the background of Friedmann–Robertson–Walker Universe, there exists Hawking radiation which comes from the cosmic apparent horizon due to quantum effect. Although the Hawking radiation on the late time evolution of the universe could be safely neglected, it plays an important role in the very early stage of the universe. In view of this point, we identify the temperature in the scalar field potential with the Hawking temperature of cosmic apparent horizon. Then we find a nonsingular universe sourced by the temperature-dependent scalar field. We find that the universe could be created from a de Sitter phase which has the Planck energy density. Thus the Big-Bang singularity is avoided.

    2011-01-01

    In this paper we present a method to obtain Banach spaces of universal and almost-universal disposition with respect to a given class $\\mathfrak M$ of normed spaces. The method produces, among other, the Gurari\\u{\\i} space $\\mathcal G$ (the only separable Banach space of almost-universal disposition with respect to the class $\\mathfrak F$ of finite dimensional spaces), or the Kubis space $\\mathcal K$ (under {\\sf CH}, the only Banach space with the density character the continuum which is of universal disposition with respect to the class $\\mathfrak S$ of separable spaces). We moreover show that $\\mathcal K$ is not isomorphic to a subspace of any $C(K)$-space -- which provides a partial answer to the injective space problem-- and that --under {\\sf CH}-- it is isomorphic to an ultrapower of the Gurari\\u{\\i} space. We study further properties of spaces of universal disposition: separable injectivity, partially automorphic character and uniqueness properties.

  7. Universality of market superstatistics

    Denys, Mateusz; Gubiec, Tomasz; Kutner, Ryszard; Jagielski, Maciej; Stanley, H. Eugene

    2016-10-01

    We use a key concept of the continuous-time random walk formalism, i.e., continuous and fluctuating interevent times in which mutual dependence is taken into account, to model market fluctuation data when traders experience excessive (or superthreshold) losses or excessive (or superthreshold) profits. We analytically derive a class of "superstatistics" that accurately model empirical market activity data supplied by Bogachev, Ludescher, Tsallis, and Bunde that exhibit transition thresholds. We measure the interevent times between excessive losses and excessive profits and use the mean interevent discrete (or step) time as a control variable to derive a universal description of empirical data collapse. Our dominant superstatistic value is a power-law corrected by the lower incomplete gamma function, which asymptotically tends toward robustness but initially gives an exponential. We find that the scaling shape exponent that drives our superstatistics subordinates itself and a "superscaling" configuration emerges. Thanks to the Weibull copula function, our approach reproduces the empirically proven dependence between successive interevent times. We also use the approach to calculate a dynamic risk function and hence the dynamic VaR, which is significant in financial risk analysis. Our results indicate that there is a functional (but not literal) balance between excessive profits and excessive losses that can be described using the same body of superstatistics but different calibration values and driving parameters. We also extend our original approach to cover empirical seismic activity data (e.g., given by Corral), the interevent times of which range from minutes to years. Superpositioned superstatistics is another class of superstatistics that protects power-law behavior both for short- and long-time behaviors. These behaviors describe well the collapse of seismic activity data and capture so-called volatility clustering phenomena.

    We use a key concept of the continuous-time random walk formalism, i.e., continuous and fluctuating interevent times in which mutual dependence is taken into account, to model market fluctuation data when traders experience excessive (or superthreshold) losses or excessive (or superthreshold) profits. We analytically derive a class of "superstatistics" that accurately model empirical market activity data supplied by Bogachev, Ludescher, Tsallis, and Bunde that exhibit transition thresholds. We measure the interevent times between excessive losses and excessive profits and use the mean interevent discrete (or step) time as a control variable to derive a universal description of empirical data collapse. Our dominant superstatistic value is a power-law corrected by the lower incomplete gamma function, which asymptotically tends toward robustness but initially gives an exponential. We find that the scaling shape exponent that drives our superstatistics subordinates itself and a "superscaling" configuration emerges. Thanks to the Weibull copula function, our approach reproduces the empirically proven dependence between successive interevent times. We also use the approach to calculate a dynamic risk function and hence the dynamic VaR, which is significant in financial risk analysis. Our results indicate that there is a functional (but not literal) balance between excessive profits and excessive losses that can be described using the same body of superstatistics but different calibration values and driving parameters. We also extend our original approach to cover empirical seismic activity data (e.g., given by Corral), the interevent times of which range from minutes to years. Superpositioned superstatistics is another class of superstatistics that protects power-law behavior both for short- and long-time behaviors. These behaviors describe well the collapse of seismic activity data and capture so-called volatility clustering phenomena.

    In distant 1972, within framework of the Internal Clinic, a cardiologic department was organized which was soon, on 29.XII.1974, transformed into the Cardiology Clinic, later the Institute for Heart Diseases, and in 2008 was renamed the University Cardiology Clinic. The greater part of its foundation was possible owing to Prof. Dimitar Arsov and Prof. Radovan Percinkovski, who was the clinic's first director in the period from 1974 to 1984. In 1985, the Clinic moved into its own new building, and in that way was physically detached from the Internal Clinics. Until its move to the new building, the Clinic functioned in the Internal Clinics building, organized as an outpatient polyclinic and inpatient infirmary department with clinical beds, a coronary intensive care unit and a haemodynamics laboratory equipped with the most modern equipment of that time. Today the Clinic functions through two integral divisions: an inpatient infirmary department which comprises an intensive coronary care unit and fourteen wards which altogether have 139 clinical beds, and the diagnostic centre which comprises an emergency clinic and day hospital, a communal and consultative outpatients' clinic functioning on a daily basis, through which some 300-350 patients pass every day, and diagnostic laboratories with a capacity of nearly 100 non-invasive and 20-30 invasive diagnostic procedures daily. The Clinic is a teaching base, and its doctors are educators of students at the Medical, Dental and Pharmacy Faculties, and also of students at the High School for Nurses and X-ray technicians, but also for those in Internal Medicine and especially Cardiology. The Clinic is also a base for scientific Masters' and post-doctoral studies, and such higher degrees are achieved not only by doctors who work here, but also by doctors from Medical Centres both in the country and abroad. Doctors working in this institution publish widely, not only a great number of books and monographs, but also original

    The Soldier Universal Robot Controller (SURC) is a modular OCU designed for simultaneous control of heterogeneous unmanned vehicles. It has a well defined, published API., defined using XML schemas, that allows other potential users of the system to develop their own modules for rapid integration with SURC. The SURC architecture is broken down into three layers: User Interface, Core Functions, and Transport. The User Interface layer is the front end module which provides the human computer interface for user control of robots. The Core layer is further divided into the following modules: Capabilities, Tactical, Mobility, and World Model. The Capabilities module keeps track of the known robots and provides a list of specifications and services. The Mobility module provides path planning via D*, while the Tactical module provides higher level mission planning (multi-agent/multi-mission) capabilities for collaborative operations. The World Model module is a relational database which stores world model objects. Finally, a Transport module provides translation from the SURC architecture to the robot specific messaging protocols (such as JAUS). This allows fast integration of new robot protocols into an existing SURC implementation to enable a new system to rapidly leverage existing SURC capabilities. The communication between different modules within the SURC architecture is done via XML. This gives developers and users the flexibility to extend existing messages without breaking backwards compatibility. The modularity of SURC offers users and developers alike the capability to create custom modules and plug them into place, as long as they follow the pre defined messaging API for that module.

  11. Universality and Beyond

    Full Text Available I discuss the impact of a finite effective range, r, on systems with a large two-body scattering length, a. In particular, I show how observables can be written as an expansion around the “universal”, or large-scatteringlength limit. The parameter governing this expansion is the ratio r/a. In few-nucleon systems the ratio r/a has a value of about 1/3, and so such corrections are essential in producing good agreement between theory and data. Hence, I first show how these effects range play a key role in making the so-called “pionless” effective field theory a successful descriptor of low-energy processes in the NN system. I then move to the NNN system, and review predictions for the energy-dependence of observables there. However, the beautiful Efimov physics associated with the presence of a large scattering length is not fully revealed in the NNN system, precisely because r/a corrections are large. I therefore turn to cold atomic gases and show that there are some important recent experiments where physics “beyond universality” affects the data. In the process I demonstrate that an additional piece of short-distance physics is necessary to renormalize scattering-length-dependent observables in the three-body system once corrections ∼ r are considered. Finally, I discuss recent initial efforts to compute r/a corrections to the predictions of universality for the four-body system.

    In this work, we describe a strategy for the detection and characterization of microorganisms associated with a potential biological warfare attack or a natural outbreak of an emerging infectious disease. This approach, termed TIGER (Triangulation Identification for the Genetic Evaluation of Risks), relies on mass spectrometry-derived base composition signatures obtained from PCR amplification of broadly conserved regions of the microbial genome(s) in a sample. The sample can be derived from air filtration devices, clinical samples, or other sources. Core to this approach are "intelligent PCR primers" that target broadly conserved regions of microbial genomes that flank variable regions. This approach requires that high-performance mass measurements be made on PCR products in the 80-140 bp size range in a high-throughput, robust modality. As will be demonstrated, the concept is equally applicable to bacteria and viruses and could be further applied to fungi and protozoa. In addition to describing the fundamental strategy of this approach, several specific examples of TIGER are presented that illustrate the impact this approach could have on the way biological weapons attacks are detected and the way that the etiologies of infectious diseases are determined. The first example illustrates how any bacterial species might be identified, using Bacillus anthracis as the test agent. The second example demonstrates how DNA-genome viruses are identified using five members of Poxviridae family, whose members includes Variola virus, the agent responsible for smallpox. The third example demonstrates how RNA-genome viruses are identified using the Alphaviruses (VEE, WEE, and EEE) as representative examples. These examples illustrate how the TIGER technology can be applied to create a universal identification strategy for all pathogens, including those that infect humans, livestock, and plants.

    Full Text Available There are a variety of ranking systems for universities throughout the different continents of the world. The majority of the world ranking systems have paid special attention toward evaluation of universities and higher education institutions at the national and international level. This paper tries to study the similarities and status of top Asian universities in the list of top 200 universities by these world ranking systems. Findings show that there are some parallelisms among these international rankings. For example it was found some correlations between QS-Webometrics rankings (R= 0.78; QS-THE rankings (R= 0.53; and Shanghai-HEEACT rankings (R= 0.58. The highest correlation rate belongs to QS-Webometrics (R=0.78. The findings show no evidence to prove that the origin country of ranking system has any bias toward the rank of universities of its own country among other countries. For instance QS ranking of the United States classifies many universities of China and Japan as top Asian universities. HEEACT Ranking System of Taiwan includes just one university of Taiwan in the high ranking category (as other rankings do. Shanghai Ranking of China assigns a lower grade to universities of China and Hong Kong in comparison with QS ranking of the USA. Finally, some suggestions are made to improve the benefits of the ranking systems in order to promote the situation of higher education in the world, and recommendations for combining the indicators of these ranking systems to have a more comprehensive one for the world.

The aim of the article is to define the importance of participation in World or National universities rankings for higher university institutions as an effective tool in development and improvement of higher education system in total. The results of the analysis. Today the educational market actively interact universities (enterprises that provide educational services and consumers (students who choose university and receive services. The main feature is the intangibility of educational services. Education is intangible and therefore difficult to assess its quality until purchased. Educational services require engineering experience of beneficiaries: university should make a clear image of what perception of reality and knowledge it wants to form for customer. It is important to develop together operational and contextual reinforcements of this impression. Educational services also feature inseparability of service provider. The process of providing educational services and consumption are almost always simultaneous. It should be mentioned that for a long time universities functioned as closed structures, the aim of which is fundamental and applied research and commercialization of their results. Nowadays new market realities show the necessity to provide new managerial forms of modern university. The top task of any university today is not only hiring students, but search for partners and providing of scientific research also. That is where international ratings help. International ratings become indicators of prestige. Relying on the rating results many decisions are made (i. e. decision on university to study, decision on scientific or business partnership. The most authoritative international university rankings are ARWU, QS World University Ranking and Times Higher Education. Ukrainian universities should focus on them in planning their foreign marketing policy. University rankings can be a competitive business

    Weak gravitational lensing is an effective tool to map the structure of matter in the universe, and has been used for more than ten years as a probe of the nature of dark energy. Beyond the well-established two-point summary statistics, attention is now turning to methods that use the full statistical information available in the lensing observables, through analysis of the reconstructed shear field. This offers an opportunity to take advantage of powerful deep learning methods for image analysis. We present two early studies that demonstrate that deep learning can be used to characterise features in weak lensing convergence maps, and to identify the underlying cosmological model that produced them.We developed an unsupervised Denoising Convolutional Autoencoder model in order to learn an abstract representation directly from our data. This model uses a convolution-deconvolution architecture, which is fed with input data (corrupted with binomial noise to prevent over-fitting). Our model effectively trains itself to minimize the mean-squared error between the input and the output using gradient descent, resulting in a model which, theoretically, is broad enough to tackle other similarly structured problems. Using this model we were able to successfully reconstruct simulated convergence maps and identify the structures in them. We also determined which structures had the highest “importance” - i.e. which structures were most typical of the data. We note that the structures that had the highest importance in our reconstruction were around high mass concentrations, but were highly non-Gaussian.We also developed a supervised Convolutional Neural Network (CNN) for classification of weak lensing convergence maps from two different simulated theoretical models. The CNN uses a softmax classifier which minimizes a binary cross-entropy loss between the estimated distribution and true distribution. In other words, given an unseen convergence map the trained CNN determines

    Four hundred years ago two astronomical world views hung in the balance: the geocentric and the heliocentric. Today astronomy faces a similar choice between two grand world views: a purely physical universe, in which cosmic evolution commonly ends in planets, stars and galaxies, and a biological universe, in which cosmic evolution routinely results in life, mind and intelligence. Astrobiology is the science providing the data to make this critical choice. This 20th century overview shows how we have arrived at the view that cosmic evolution may have resulted in life and intelligence in the universe. It examines how our astronomical world view has changed over the last century, recalls the opinions of astronomical pioneers like Russell, Shapley, and Struve on life in the universe, and shows how planetary science, planetary systems science, origins of life studies and SETI have combined to form a new discipline. Astrobiology now commands \\$50 million in direct funding from NASA, funds 15 Astrobiology Institute members around the country and four affiliates around the world, and seeks to answer one of astronomy's oldest questions. Whether we live in a mostly physical universe, as exemplified in Isaac Asimov's Foundation series, or in a biological universe, as portrayed in Arthur C. Clarke's works, this reality will have profound consequences, no less than the Copernican theory. Astrobiology also looks to the future of life; taking a long-term ``Stapledonian" view, it is possible we may live in a postbiological universe.

According to it, gravity dominates the expan- sion ( matter era until the age of T ⋆ = 3 : 214 Gyr and, after that, dark energy dominates ( dark energy era leading to an eternal expansion, no matter if the Universe is closed, flat or open. In this paper we consider only the closed version and show that there is an upper limit for the size of the radial comoving coordinate, beyond which nothing is observed by our fundamental observer, on Earth. Our observable Universe may be only a tiny portion of a much bigger Universe most of it unobservable to us. This leads to the idea that an endless number of other fundamental observers may live on equal number of Universes similar to ours. Either we talk about many Universes — Multiverse — or about an unique Universe, only part of it observable to us.

    Research into the oral and literary traditions of scholastic education usually emphasizes the significance of the world in late medieval pedagogy. This paper suggests that coded hand signals provided early university scholars with an important non-verbal means of communication too. Using illustrations of classroom scenes from early university manuscripts, this paper analyzes the artistic conventions for representating gestures that these images embody. By building up a typology of these gesticulations, it demonstrates that the producers of these images and their audience shared a perception of scholastic education that embraced a sophisticated understanding of the activities associated with university education.

    Universal planetary tectonics (supertectonics) G. Kochemasov IGEM of the Russian Academy of Sciences, Moscow, Russia, kochem.36@mail.ru The wave planetology [1-3 & others] proceeds from the following: "planetary structures are made by orbits and rotations". A uniform reason makes uniform structures. Inertia-gravity waves arising in planetary bodies due to their movements in Keplerian elliptical orbits with periodically changing accelerations warp these bodies in such way that they acquire polyhedron shapes (after interference of standing waves of four directions). Strong Newtonian gravity makes bodies larger than ~400 to 500 km in diameter globular and polyhedra are rarely seen. Only geomorphologic, geologic and geophysical mapping can develop these hidden structures. But small bodies, normally less than ~ 300 to 400 km in diameter, often show parts of the polyhedra, rarely fully developed forms (the asteroid Steins and satellite Amalthea present rather perfect forms of "diamond"). Depending on warping wavelengths (they make harmonics) various Plato's figures superimposed on each other can be distinguished. The fundamental wave 1 produces a tetrahedron, intrinsically dichotomic figure in which a vertex (contraction) always is opposed to a face (expansion). From the recent examples the best is the saturnian northern hexagon (a face) opposed to the southern hurricane (a vertex). The first overtone wave 2 is responsible for creation of structural octahedra. Whole ‘diamonds" and their parts are known [4, 5]. Other overtones produce less developed (because of smaller wave amplitudes) planetary shapes complicating main forms. Thus, the first common structural peculiarity of planetary bodies is their polyhedron nature. Not less important is the second common structural peculiarity. As all globular or smaller more or less isometric bodies rotate, they have an angular momentum. It is inevitably different in tropic and extra-tropic belts having uneven radii or distances to

    Full Text Available It is widely accepted that universities can play critical roles in promoting sustainability. In the United States and China, many universities have initiated sustainability programs. Employing Indiana University, Bloomington, the U.S. (IUB and Tsinghua University, Beijing, China (Tsinghua as two cases, we examine the conceptualization and implementation of university sustainability programs through a comparison of their respective definitions, goals, organizational dynamics, and strategies. We find that IUB’s sustainability scheme is more detailed and specific, while Tsinghua’s is more general; this is principally attributable to differences in national and local contexts. Furthermore, IUB values the environmental, economic, and social aspects of university sustainability equally, while Tsinghua focuses more on the environmental aspect. In addition, IUB has a more loosely-structured and more inclusive sustainability organizational dynamic while Tsinghua has a more hierarchical one. This comparative study helps us to understand how these two research universities understand and implement sustainability within the respective cultural, political, and institutional contexts of the United States and China.

The Hamiltonian has a pair of invariant operators for each universe with conserved momenta of the fields that play a role of the annihilation and the creation operators and that construct various quantum states for the universe. The closed universe exhibits an interesting feature of transitions from stable states to tachyonic states depending on the conserved momenta of the fields. In the classical forbidden unstable regime, the quantum states have googolplex growing position and conjugate momentum dispersions, which defy any measurements of the position of the universe.

  16. Refinements in the Jungle Universes

    How can effective barotropic matter emerge from the interaction of cosmological fluids in an isotropic and homogeneous cosmological model? The dynamics of homogeneous and isotropic Friedmann-Lema\\^itre-Robertson-Walker universes is a natural special case of generalized Lotka-Volterra systems where each of the universe's fluid components can be seen as a competitive species in a predator-prey model. (Jungle universe : arXiv:1306.1037) In addition to numerical simulations illustrating this behaviour among the barotropic fluids filling the universe, we analytically pinpoint that effective time-dependent barotropic indices can arise from a physical coupling between those fluids whose dynamics could then look like that of another type of cosmic fluid, such as a cosmological constant. Since the nature of dark energy is still unknown, this dynamical approach could help understanding some of the properties of dark matter and dark energy at large cosmological scales.

  17. Emergent Universe with Particle Production

    2016-10-01

    The possibility of an emergent universe solution to Einstein's field equations allowing for an irreversible creation of matter at the expense of the gravitational field is shown. With the universe being chosen as spatially flat FRW spacetime together with equation of state proposed in Mukherjee et al. (Class. Quant. Grav. 23, 6927, 2006), the solution exists when the ratio of the phenomenological matter creation rate to the number density times the Hubble parameter is a number β of the order of unity and independent of time. The thermodynamic behaviour is also determined for this solution. Interestingly, we also find that an emergent universe scenario is present with usual equation of state in cosmology when the matter creation rate is chosen to be a constant. More general class of emergent universe solutions are also discussed.

    2010-09-01

    Full Text Available This article surveys studies on universally balanced properties of cooperative games defined in a succinct form. In particular, we focus on combinatorial optimization games in which the values to coalitions are defined through linear optimization programs, possibly combinatorial, that is subject to integer constraints. In economic settings, the integer requirement reflects some forms of indivisibility. We are interested in the classes of games that guarantee a non-empty core no matter what are the admissible values assigned to the parameters defining these programs. We call such classes universally balanced. We present characterization and complexity results on the universally balancedness property for some classes of interesting combinatorial optimization games. In particular, we focus on the algorithmic properties for identifying universally balancedness for the games under discussion.

    Full Text Available The present article sets out to clarify the concepts of storytelling and branding, with a focus on university branding and visual identity – the latter being a vital element to a brand’s uniqueness. Storytelling is an important method of brand construction, and it entails a strong power of seduction. Branding is increasingly more about storytelling. Practically, a story is an image made up of facts, feelings and interpretations, which are often told to us solely by the university itself. As such, the brand appears on the market accompanied by its identity. Identity is what we aim to express with help of the brand. Implementing a system of visual identity that would help to harmoniously develop a university brand requires a handbook of visual identity. The present article aims to be a starting point for such a handbook serving the University of Bucharest, which currently does not own such a handbook

  5. Universe creation on a computer

    Science.gov (United States)

    McCabe, Gordon

    The purpose of this paper is to provide an account of the epistemology and metaphysics of universe creation on a computer. The paper begins with F.J. Tipler's argument that our experience is indistinguishable from the experience of someone embedded in a perfect computer simulation of our own universe, hence we cannot know whether or not we are part of such a computer program ourselves. Tipler's argument is treated as a special case of epistemological scepticism, in a similar vein to 'brain-in-a-vat' arguments. It is argued that Tipler's hypothesis that our universe is a program running on a digital computer in another universe, generates empirical predictions, and is therefore a falsifiable hypothesis. The computer program hypothesis is also treated as a hypothesis about what exists beyond the physical world, and is compared with Kant's metaphysics of noumena. It is argued that if our universe is a program running on a digital computer, then our universe must have compact spatial topology, and the possibilities of observationally testing this prediction are considered. The possibility of testing the computer program hypothesis with the value of the density parameter Ω0 is also analysed. The informational requirements for a computer to represent a universe exactly and completely are considered. Consequent doubt is thrown upon Tipler's claim that if a hierarchy of computer universes exists, we would not be able to know which 'level of implementation' our universe exists at. It is then argued that a digital computer simulation of a universe, or any other physical system, does not provide a realisation of that universe or system. It is argued that a digital computer simulation of a physical system is not objectively related to that physical system, and therefore cannot exist as anything else other than a physical process occurring upon the components of the computer. It is concluded that Tipler's sceptical hypothesis, and a related hypothesis from Bostrom, cannot be

    We analyze the constituents stocks of the Dow Jones Industrial Average and the Standard & Poor's 100 index of the NYSE stock exchange market. Surprisingly, we discovered that the distribution of the fluctuations of the cubic root of the squared daily return are close to the universal non-parametric Bramwell-Holdsworth-Pinton (BHP) distribution. Since the BHP probability density function appears in several other dissimilar phenomena, our result reveals an universal feature of the stock exchange market.

We focus on models with one universal extra dimension, compactified on an S{sub 1}/Z{sub 2} orbifold. We revisit calculations of Kaluza-Klein (KK) dark matter without an assumption of the KK mass degeneracy including all possible coannihilations. We then contrast the experimental signatures of low energy supersymmetry and UED.

  13. A Universe without Weak Interactions

    Energy Technology Data Exchange (ETDEWEB)

    Harnik, Roni; Kribs, Graham D.; Perez, Gilad

    2006-04-07

    A universe without weak interactions is constructed that undergoes big-bang nucleosynthesis, matter domination, structure formation, and star formation. The stars in this universe are able to burn for billions of years, synthesize elements up to iron, and undergo supernova explosions, dispersing heavy elements into the interstellar medium. These definitive claims are supported by a detailed analysis where this hypothetical ''Weakless Universe'' is matched to our Universe by simultaneously adjusting Standard Model and cosmological parameters. For instance, chemistry and nuclear physics are essentially unchanged. The apparent habitability of the Weakless Universe suggests that the anthropic principle does not determine the scale of electroweak breaking, or even require that it be smaller than the Planck scale, so long as technically natural parameters may be suitably adjusted. Whether the multi-parameter adjustment is realized or probable is dependent on the ultraviolet completion, such as the string landscape. Considering a similar analysis for the cosmological constant, however, we argue that no adjustments of other parameters are able to allow the cosmological constant to raise up even remotely close to the Planck scale while obtaining macroscopic structure. The fine-tuning problems associated with the electroweak breaking scale and the cosmological constant therefore appear to be qualitatively different from the perspective of obtaining a habitable universe.

    Full Text Available The study was intended to recognize and replicate the Yukl’s (1989-2004 behavioral taxonomies in the university settings in Sindh. A comprehensive questionnaire based on the items in taxonomies was developed, face validity of the questionnaire was test and found suitable. A total of 90 university Deans and head of Departments were randomly selected from public and private universities of Sindh. Categorical reliability of the data was checked and found highly reliable. The majority of the respondents were male, post graduate, above 50 years of age, married and had more than 15 years of experience. The statistical analysis describes the typical Sindhi culture among the respondents. A large number of university leadership focused on the relation as compared to task and change at the universities. This research also supports partial replication of three dimensions i.e., Relation, Task and Change as Yukl’s behavioral taxonomies with first order factor analysis. Relation factor was replicated completely, while other two were replicated in two different facets each i.e., Change was replicated in two facets – Improvement and Process and Task was also replicated in two facets – Improvement and Process. Making a second order factor analysis assured these two factors were replicated completely.

    The ESA Euclid mission aims to understand why the expansion of the Universe is accelerating and pin down the source responsible for the acceleration. It will uncover the very nature of dark energy and gravitation by measuring with exquisite accuracy the expansion rate of the Universe and the growth rate of structure formation in the Universe. To achieve its objectives Euclid will observe the distribution of dark matter in the Universe by measuring shapes of weakly distorted distant galaxies lensed by foreground cosmic structures with the VIS imaging instrument. In parallel, Euclid will analyse the clustering of galaxies and the distribution of clusters of galaxies by using spectroscopy and measuring redshifts of galaxies with the NISP photometer and spectrometer instrument. The Euclid mission will observe one third of the sky (15,000 deg2) to collect data on several billion galaxies spread over the last ten billion years. In this presentation I will report on the considerable technical and scientific progresses made since COSPAR 2014, on behalf of the Euclid Collaboration. The recent mission PDR that has been passed successfully shows that Euclid should meet its requirements and achieve its primary scientific objectives to map the dark universe. The most recent forecasts and constraints on dark energy, gravity, dark matter and inflation will be presented.

    This thesis concentrates on the accelerated expansion of the Universe recently explored by measurements of redshift and luminosity-distance relations of type Ia Supernovae. We have considered a model of the universe filled with modified Chaplygin gas and barotropic fluid. The role of dynamical cosmological constant has been explored with Modified Chaplygin Gas as the background fluid. Various phenomenological models for \\Lambda have been studied in presence of the gravitational constant G to be constant or time dependent. A new form of the well known Chaplygin gas model has been presented by introducing inhomogeneity in the EOS. This model explains w=-1 crossing. An interaction of this model with the scalar field has also been investigated through a phenomenological coupling function. Tachyonic field has been depicted as dark energy model to represent the present acceleration of the Universe. A mixture of the tachyonic fluid has been considered with Generalized Chaplygin Gas to show the role of the later as a...

  1. Reionization of an Inhomogeneous Universe

    Full radiative transfer in 3D space has been solved to pursue the reionization history in an inhomogeneous universe. It has been shown that the reionization of an inhomogeneous universe is not a prompt event, but a fairly slow process. Also, QSO absorption line systems are simulated with using the results of radiative transfer calculations. Ly$\\alpha$ continuum depression implies that the metagalactic UV intensity decreases rapidly with $z$ at $z>5$, and the reionization must have taken place between $z=6$ and 10. Finally, it is stressed that H$\\alpha$ forest is a more powerful tool to probe the reionization history and the density fluctuations in the universe at $z>5$.

  8. Sustaining community-university partnerships

    Directory of Open Access Journals (Sweden)

    Simon Northmore

    2011-11-01

    Full Text Available In recent years there has been a huge growth in the academic literature on community-university partnership working. However, much of this is practice based and the issue of how such partnerships can be sustained over time is not adequately reflected in the literature. This introductory chapter lays the foundations for the subsequent thirteen articles by first discussing notions of sustainability, in part by providing a brief overview of the Community University Partnership Programme (Cupp at the University of Brighton, UK. After a period of rapid growth, we are increasingly concerned with how to sustain the reciprocal relationships that underpin long-term engagement, a situation exacerbated by potential looming funding cuts. Paradoxically, however, this article suggests that while funding is an important element of sustainability, the current economic challenges may help to generate sustainability as community-university partnerships are forced to examine what other factors contribute to lasting relationships. It is these ‘other factors’ that the articles in this collection fruitfully explore. Coming from the United States, the United Kingdom and Australia, they examine the core research question that concerns us: how do we address the challenges of building sustainable community-university partnerships, especially with disadvantaged and excluded communities, at a time of diminishing resources? Despite the wide range of community needs and methodological diversity involved, the articles suggest that some common characteristics underpin sustainability. These include: genuine reciprocity; mutual learning; and a creative approach to partnership building that recognises the diverse purposes of partners. This introductory chapter concludes that there is a need to further refine our understanding of community-university partnerships through the development of more theoretical models of sustainability.

    Full Text Available This paper investigates the G ̈odel’s exact solution of the Einstein equations which describes a stationary homogeneous cosmological Universe inducing closed timelike curves CTCs. This model is generally dismissed because it exhibits a rotational sym- metry and it requires a non zero cosmological constant in contradiction with the current astronomical observations. If the cosmological term is assumed to be slightly variable, we show that this metric can be compatible with the Hubble expansion, which makes the G ̈odel model a viable representation of our Universe.

    A fundamental assumption in the standard model of cosmology is that the Universe is isotropic on large scales. Breaking this assumption leads to a set of solutions to Einstein's field equations, known as Bianchi cosmologies, only a subset of which have ever been tested against data. For the first time, we consider all degrees of freedom in these solutions to conduct a general test of isotropy using cosmic microwave background temperature and polarization data from Planck. For the vector mode (associated with vorticity), we obtain a limit on the anisotropic expansion of (σ_{V}/H)_{0}Universe is strongly disfavored, with odds of 121 000:1 against.

  16. The D-material universe

    OpenAIRE

    2016-01-01

    In a previous publication by some of the authors (N.E.M., M.S. and M.F.Y.), we have argued that the "D-material universe", that is a model of a brane world propagating in a higher-dimensional bulk populated by collections of D-particle stringy defects, provides a model for the growth of large-scale structure in the universe via the vector field in its spectrum. The latter corresponds to D-particle recoil velocity excitations as a result of the interactions of the defects with stringy matter a...

    We investigate a fluid description of inflationary cosmology. It is shown that the three observables of the inflationary universe: the spectral index of the curvature perturbations, the tensor-to-scalar ratio of the density perturbations, and the running of the spectral index, can be compatible with the Planck analysis. In addition, we reconstruct the equation of state (EoS) for a fluid from the spectral index of the curvature perturbations consistent with the Planck results. We explicitly demonstrate that the universe can gracefully exit from inflation in the reconstructed fluid models. Furthermore, we explore the singular inflation for a fluid model.

  18. The Origin of the Universe

    DEFF Research Database (Denmark)

    Ramazanov, Sabir

    Recently, it has been proposed to relate properties of primordial scalar perturbations to the conformal invariance of some very early Universe models. A concrete realization of this idea is given in the context of the conformal rolling scenario. The main ingredient of the latter is the complex...... of the early Universe, where the potential role of conformal symmetries is understood from a much broader prospective. In this picture, proposed by Hinterbichler and Khoury, conformal rolling scenario is just a particular case in a myriad of possible models. We review the main novelties and assumptions...

    Are we witnessing the privatization of public university research libraries? There is convincing evidence that, in an era of decreasing state support for public higher education, public universities have begun to resemble private universities, particularly in their sources of revenue. A number of indicators demonstrate that public universities,…

    Continued advances in the field of histo-pathology (and cyto-pathology) over the past two decades have resulted in dramatic changes in the manner in which these disciplines are now practiced. This is especially true in the setting of a large university hospital where the role of pathologists as clinicians (diagnosticians), undergraduate and postgraduate educators, and researchers has evolved considerably. The world around us has changed significantly during this period bringing about a considerable change in our lifestyles and the way we live. This is the world of the internet and the world-wide web, the world of Google and Wikipedia, of Youtube and Facebook where anyone can obtain any information one desires at the push of a button. The practice of histo (and cyto) pathology has also evolved in line with these changes. For those practicing this discipline in a poor, developing country these changes have been breathtaking. This is an attempt to document these changes as experienced by histo (and cyto) pathologists practicing in the biggest center for Histopathology in Pakistan, a developing country in South Asia with a large (180 million) and ever growing population. The Section of Histopathology, Department of Pathology and Microbiology at the Aga Khan University Hospital (AKUH) in Karachi, Pakistan's largest city has since its inception in the mid-1980s transformed the way histopathology is practiced in Pakistan by incorporating modern methods and rescuing histopathology in Pakistan from the primitive and outdated groove in which it was stuck for decades. It set histopathology in Pakistan firmly on the path of modernity and change which are essential for better patient management and care through accurate and complete diagnosis and more recently prognostic and predictive information as well.

    Raup, David M.

    Animals lacking humanoid intelligence have evolved systems indistinguishable in function, if not in structure, from systems built by humans. Although radio communication has never been verified in animals, it is completely feasible biologically. If such systems are present in non-intelligent organisms on other planets, then our chances of detecting life in the universe by current SETI methods are greatly enhanced.

  11. Effective theories of universal theories

    Wells, James D

    2015-01-01

    It is well-known but sometimes overlooked that constraints on the oblique parameters (most notably $S$ and $T$ parameters) are only applicable to a special class of new physics scenarios known as universal theories. In the effective field theory (EFT) framework, the oblique parameters should not be associated with Wilson coefficients in a particular operator basis, unless restrictions have been imposed on the EFT so that it describes universal theories. We work out these restrictions, and present a detailed EFT analysis of universal theories. We find that at the dimension-6 level, universal theories are completely characterized by 16 parameters. They are conveniently chosen to be: 5 oblique parameters that agree with the commonly-adopted ones, 4 anomalous triple-gauge couplings, 3 rescaling factors for the $h^3$, $hff$, $hVV$ vertices, 3 parameters for $hVV$ vertices absent in the Standard Model, and 1 four-fermion coupling of order $y_f^2$. All these parameters are defined in an unambiguous and basis-indepen...

  15. Discovery of Uniformly Expanding Universe

    Directory of Open Access Journals (Sweden)

    Cahill R. T.

    2012-01-01

    Full Text Available Saul Perlmutter and the Brian Schmidt – Adam Riess teams reported that their Friedmann-model GR-based analysis of their supernovae magnitude-redshift data re- vealed a new phenomenon of “dark energy” which, it is claimed, forms 73% of the energy / matter density of the present-epoch universe, and which is linked to the further claim of an accelerating expansion of the universe. In 2011 Perlmutter, Schmidt and Riess received the Nobel Prize in Physics “for the discovery of the accelerating ex- pansion of the Universe through observations of distant supernovae”. Here it is shown that (i a generic model-independent analysis of this data reveals a uniformly expanding universe, (ii their analysis actually used Newtonian gravity, and finally (iii the data, as well as the CMB fluctuation data, does not require “dark energy” nor “dark matter”, but instead reveals the phenomenon of a dynamical space, which is absent from the Friedmann model.

  20. William Band at Yenching University

    Science.gov (United States)

    Hu, Danian

    2008-04-01

    William Band (1906-1993) has been widely remembered by his American colleagues and students as ``a fine physicist and teacher,'' who taught at Washington State University in Pullman between 1949 and 1971 and authored Introduction to Quantum Statistics (1954) and Introduction to Mathematical Physics (1959). Not many, however, knew much about Band's early career, which was very ``uncommon and eventful.'' Born in England, Band graduated from University of Liverpool in 1927 with an MsSc degree in physics. Instead of pursuing his Ph.D. at Cambridge, he chose to teach physics at Yenching University, a prestigious Christian university in Beijing, China. Arriving in 1929, Band established his career at Yenching, where he taught and researched the theory of relativity and quantum mechanics, pioneered the study on low-temperature superconductivity in China, founded the country's first graduate program in physics, and chaired the Physics Department for 10 years until he fled from Yenching upon hearing of the attack on Pearl Harbor. It took him two years to cross Japanese occupied areas under the escort of the Communist force; he left China in early 1945. This presentation will explore Band's motivation to work in China and his contributions to the Chinese physics research and education.
