ISM properties in low-metallicity environments I. mid-infrared spectra of dwarf galaxies

We present new ISOCAM mid-infrared spectra of three starbursting nearby dwarf galaxies, NGC1569, IIZw40, NGC1140 and the 30Dor region of the LMC and explore the properties of the ISM in low-metallicity environments, also using additional sources from the literature. We analyse the various components of the ISM probed by the mid-infrared observations and compare them with other Galactic and extragalactic objects. The MIR spectra of the low-metallicity starburst sources are dominated by the [NeIII] and [SIV] lines, as well as a steeply rising dust continuum. PAH bands are generaly faint, both locally and averaged over the full galaxy, in stark contrast to dustier starburst galaxies, where the PAH features are very prominant and even dominate on global scales. The hardness of the modeled interstellar radiation fields for the dwarf galaxies increases as the presence of PAH band emission becomes less pronounced. The [NeIII]/[NeII] ratios averaged over the full galaxy are strikingly high, often >10. Thus, the hard radiation fields are pronounced and pervasive. We find a prominent correlation between the PAHs/VSGs and the [NeIII]/[NeII] ratios for a wide range of objects, including the low metallicity galaxies as well as Galactic HII regions and other metal-rich galaxies. This effect is consistent with the hardness of the interstellar radiation field playing a major role in the destruction of PAHs in the low metallicity ISM. We see a PAHs/VSGs and metallicity correlation, also found by Engelbracht et al. (2005) for a larger survey. Combined effects of metallicity and radiation field seem to be playing important roles in the observed behavior of PAHs in the low metallicity systems.
The queue protocol: a deadlock-free, homogeneous, non-two-phase locking protocol

The M-pitfall protocol (MPP) is the most general homogeneous non-two-phase locking protocol which supports shared and exclusive locks. It has two major disadvantages: it is not deadlock-free and it has the paradoxical property that concurrency is often reduced if shared locks are used instead of exclusive locks. This paper presents a new protocol, the Queue Protocol (QP), which removes these deficiencies. Although the QP can be regarded an enhancement of the MPP, pitfalls are no more used in the QP; thus, the QP has the further advantage that processing overhead due to pitfalls is avoided.
Lung Cancer Survival Modelling using Adaptive Neuro-fuzzy Inference System

— The development of medical AI has been related to the growth of AI programs intended to help in the formulation of a diagnosis, prognosis and decision making. Approaches such as Artificial Neural Networks and fuzzy inference systems are widely used for expert behaviour modelling. The main aim of this project is to develop an approach for modelling lung cancer survival based on Adaptive neuro-fuzzy inference System where we combine both the learning capabilities of a neural network and reasoning capabilities of fuzzy logic in order to give enhanced prediction capabilities, as compared to using a single methodology alone.
Generation of multiple synthesis inventories by a bootstrapping procedure

In concatenative speech synthesis systems, the generation of a unit inventory is a tedious task. However, some applications demand multiple voices. A semiautomatic method to generate unit inventories is proposed. The units are segmented out of carrier phrases by means of dynamic time warping alignment with a synthesized utterance. This requires at least one existing inventory. The availability of several existing inventories will improve the likelihood of finding one with similar voice characteristics, which will improve the accuracy of results. The method is a bootstrapping procedure. To choose the best segmentation out of a set (e.g. aligned with each voice already implemented), a penalty system was developed that uses timing constraints. The results were compared with manually corrected segmentations and show the validity of this approach.
The Large N Limit of ${\cal N} =2,1 $ Field Theories from Threebranes in F-theory

We consider field theories arising from a large number of D3-branes near singularities in F-theory. We study the theories at various conformal points, and compute, using their conjectured string theory duals, their large $N$ spectrum of chiral primary operators. This includes, as expected, operators of fractional conformal dimensions for the theory at Argyres-Douglas points. Additional operators, which are charged under the (sometimes exceptional) global symmetries of these theories, come from the 7-branes. In the case of a $D_4$ singularity we compare our results with field theory and find agreement for large $N$. Finally, we consider deformations away from the conformal points, which involve finding new supergravity solutions for the geometry produced by the 3-branes in the 7-brane background. We also discuss 3-branes in a general background.
Simultaneous localization and mapping: A feature-based probabilistic approach

Simultaneous localization and mapping: A feature-based probabilistic approach This article provides an introduction to Simultaneous Localization And Mapping (SLAM), with the focus on probabilistic SLAM utilizing a feature-based description of the environment. A probabilistic formulation of the SLAM problem is introduced, and a solution based on the Extended Kalman Filter (EKF-SLAM) is shown. Important issues of convergence, consistency, observability, data association and scaling in EKF-SLAM are discussed from both theoretical and practical points of view. Major extensions to the basic EKF-SLAM method and some recent advances in SLAM are also presented.
Emotional process through autobiographical memory

Introduction Self defining Memories (SDM) are highly significant autobiographical memories that contribute to the construct of identity (Conway et al., 2004). SDM are vivid, emotional and carry the values of the individuals (Conway et al., 2004 ; Singer & Blagov, 2000). However, to the best of our knowledge, no study has evaluated psychophysiological changes that may be related to emotional processes in SDM.
Malleability of the system in overcoming limitations: functional elements.

Three different views can be found in the literature concerning the classical question in exercise physiology: what limits maximal oxygen uptake in man? Some authors believe that the limitation is the maximal rate of oxygen delivery by the cardiovascular system. Others argue that oxygen uptake is limited by the capillary bed or metabolic capacity of skeletal muscle, and the third line of thought is that no single factor can be found to be directly limiting as all links in the oxygen transport are so closely matched. The stand taken in this paper is that the skeletal muscle of man can be excluded as a limiting factor for maximal oxygen uptake in whole body exercise. It can be shown, by direct measurements, that in sedentary and in trained man maximal perfusion and oxygen utilization of skeletal muscle is so high that if all muscles in the body were engaged in intense exercise, the cardiac pump function would have to be 2-3 fold larger than it is. What happens in whole body exercise is that each muscle group receives only a fraction of the blood it can accommodate. The primary role for a larger capillary network observed in trained muscles is to keep or extend mean transit time. Elevated mitochondrial enzyme activities affect the metabolic response (i.e. lipid oxidation is elevated in trained muscles). However, these adaptations are not necessary for increasing the maximal oxygen uptake of man, as the capacity of the heart is limiting. Improved training techniques (which induce even larger improvements in cardiac pump function) may reveal that pulmonary diffusion capacity is the limiting factor.
BloomCast: Efficient Full-Text Retrieval over Unstructured P2Ps with Guaranteed Recall

Efficient and effective full-text retrieval in unstructured peer-to-peer networks remains a challenge in the research community. First, it is difficult, if not impossible, for unstructured P2P search protocols to effectively locate items with guaranteed recall rate. Second, existing schemes to improve search successful rate often rely on replicating a large number of item replicas across the wide area network, incurring a large amount of communication and storage cost. In this paper we propose BloomCast, an efficient and effective full-text retrieval scheme, in unstructured P2P networks. BloomCast is effective because it guarantees perfect recall rate with high probability. It is efficient because the overall communication cost of full-text search is reduced below a formal bound. Furthermore, by casting Bloom Filters instead of the raw documents across the network, BloomCast significantly reduces the communication cost and storage cost for replication. We demonstrate the power of BloomCast design through both mathematical proof and comprehensive simulations. Results show that BloomCast outperforms existing schemes in terms of both recall rate and communication cost.
Evolution of Rodent Pheromones: A Review of the ABPs with Comparison to the ESPs and the MUPs

Three proteinaceous pheromone families, the androgen -binding proteins (ABPs), the exocrine-gland secreting peptides (ESPs) andthe major urinary proteins (MUPs) are encoded by large gene families in the Mus musculus and Rattus norvegicusgenomes. The purpose of this article is to review what is known about the evolutionary histories of the the Abp gene family expansions in rodent s and, where appropriate, to compare them to what is known of the expansions of the Mup and Esp gene families. The issues important to these histories are the extent of the gene family expansions, the timing of their expansions and the roles played by sele ction, gene conversion and non-allelic homologous recombination (NAHR). I also compare and contrast the evolutionary histories of all three mouse gene families in light of the proposed functions of their pheromones in mouse communication.
Construction of a 4D atlas of the developing brain using non-rigid registration

In this paper we present an approach for constructing a 4D brain atlas of MR images of preterm baby infants aged between 26–44 weeks of gestation at time of scan. The method used for the creation of an average 4D atlas is based on the use of pair-wise non-rigid registration to eliminate bias in the atlas towards any of the original images. In addition, we use kernel regression to produce age-dependent anatomical templates. The resulting unbiased 4D atlas is much sharper than currently available atlases created using affine registration.
Robust Face Recognition by Sparse Local Features from a Single Image under Occlusion

Occlusion and "one sample per person" are two challenging problems for face recognition and still not well solved till now. This paper investigates the two problems and proposes a novel method based on sparse local features to solve them. The contribution of our work is three-fold: first, the key characteristics of successful applying SIFT features for face recognition are analyzed. Second, based on the analysis of SIFT features, two new sparse local feature descriptors, namely Sparse HoG and Sparse LBP are proposed and they are combined together for extracting more discriminative features from an occluded and single image of one person. Third, a new matching strategy is proposed to measure the similarity between the testing and the gallery images. The proposed method is effective and efficient for solving the occlusion and ¡®one sample per person' problem. Experimental results on the AR database show that the proposed method outperforms the original SIFT, HoG, LBP based methods and also some other existing face recognition algorithms in terms of recognition accuracy.
Theory of Quantum Annealing of an Ising Spin Glass

Probing the lowest energy configuration of a complex system by quantum annealing was recently found to be more effective than its classical, thermal counterpart. By comparing classical and quantum Monte Carlo annealing protocols on the two-dimensional random Ising model (a prototype spin glass), we confirm the superiority of quantum annealing relative to classical annealing. We also propose a theory of quantum annealing based on a cascade of Landau-Zener tunneling events. For both classical and quantum annealing, the residual energy after annealing is inversely proportional to a power of the logarithm of the annealing time, but the quantum case has a larger power that makes it faster.
Integrating curriculum: a case study of teaching Global Education

Abstract Despite widespread support for integrated approaches to teaching, classroom practice reveals a lack of implementation. This paper explores challenges and opportunities in teaching an integrated curriculum, and connects this with the contemporary notion of a twenty-first century curriculum and pedagogy. A case study of Global Education (GE) is used to delineate the complexity of issues when teachers attempt to move beyond disciplinary-based teaching approaches. We examine curriculum documents, advice for teachers on curriculum implementation, preservice teachers’ experiences in schools during Professional Experiences and national guidelines for Professional Experience. Through these data, a broad picture emerges of influences on integrating curricula in classrooms. Opportunities to integrate curriculum incorporating twenty-first century pedagogies were limited by pressures on teachers with preservice teachers rarely exposed to authentic integration. Teachers’ professional standing requires clear guidelines, which allow them to pursue important twenty-first century content and skills , for young citizens and this must begin in preservice education.
An efficient checkpoint scheme for the fast mount of flash file system

The mounting time of file system increases in embedded systems, as the capacity of flash memory keeps increasing rapidly. There is an unexpected power failure or an abnormal shutdown due to the power of mobile devices is supplied by batteries. Previous recovery schemes of the flash file system have limitation to reduce the mounting time in large flash memory and this resources constraint environment. Our goal is to reduce the reconstruction delay in flash file system. We present a state transition rate diagram of checkpoint to obtain the checkpoint interval and compute the interval of a checkpoint from the analysis of the diagram to reduce the scan time.
Intranasal Administration of Interferon Beta Attenuates Neuronal Apoptosis via the JAK1/STAT3/BCL-2 Pathway in a Rat Model of Neonatal Hypoxic-Ischemic Encephalopathy

Neonatal hypoxic-ischemic encephalopathy (HIE) is an injury that often leads to detrimental neurological deficits. Currently, there are no established therapies for HIE and it is critical to develop treatments that provide protection after HIE. The objective of this study was to investigate the ability of interferon beta (IFNβ) to provide neuroprotection and reduce apoptosis after HIE. Postnatal Day 10 rat pups were subjected to unilateral carotid artery ligation followed by 2.5 hr of exposure to hypoxia (8% O2). Intranasal administration of human recombinant IFNβ occurred 2 hr after HIE and infarct volume, body weight, neurobehavioral tests, histology, immunohistochemistry, brain water content, blood–brain barrier permeability, enzyme-linked immunosorbent assay, and Western blot were all used to evaluate various parameters. The results showed that both IFNβ and the Type 1 interferon receptor expression decreases after HIE. Intranasal administration of human recombinant IFNβ was able to be detected in the central nervous system and was able to reduce brain infarction volumes and improve neurological behavior tests 24 hr after HIE. Western blot analysis also revealed that human recombinant IFNβ treatment stimulated Stat3 and Bcl-2 expression leading to a decrease in cleaved caspase-3 expression after HIE. Positive Fluoro-Jade C staining also demonstrated that IFNβ treatment was able to decrease neuronal apoptosis. Furthermore, the beneficial effects of IFNβ treatment were reversed when a Stat3 inhibitor was applied. Also an intraperitoneal administration of human recombinant IFNβ into the systemic compartment was unable to confer the same protective effects as intranasal IFNβ treatment.
The Chilean infant mortality decline: improvement for whom? Socioeconomic and geographic inequalities in infant mortality, 1990-2005.

OBJECTIVE To measure socioeconomic inequalities and differential risk in infant mortality on national and regional levels in Chile from 1990 to 2005, and propose new policy targets. METHODS The study analysed Chilean vital events registries from 1990 to 2005 for infant mortality by maternal education, head of household occupational status, cause, age and location of death. Annual infant mortality rates and relative risk were calculated by maternal education and head of household occupational status for each cause and age of death. Socioeconomic inequalities were then mapped to 29 regional health services. FINDINGS Reductions in the national infant mortality rate were driven by reductions among highly educated mothers, while recent stagnation in the national rate is caused by high levels of infant mortality among uneducated mothers. These vulnerable households are particularly prone to infant mortality risk due to infectious disease and trauma. We also identify clustering of high socioeconomic inequalities in infant mortality throughout the poorer north, indigenous south and densely populated metropolitan centre of Santiago. Finally, we report large inequities in vital statistics coverage, with infant deaths among vulnerable households much more likely to be inadequately defined than in the remaining population. CONCLUSION These results indicate that the socioeconomically disadvantaged in Chile are at a significantly higher risk for infant mortality by infectious diseases and trauma during the first month of life. Efforts to reduce national infant mortality in Chile and other countries must involve policies that target child survival for at-risk populations for specific diseases, ages and locations.
Efficiency optimized AC charging waveform for GaN bidirectional PHEV Battery Charger

Sinusoidal charging can boost the power density of GaN-based battery charger with the penalty of dropped efficiency due to hard-switching. In this paper, different AC charging waveforms are investigated to achieve better charger efficiency with slightly increased DC link capacitance. It turns out that PWM-zero-off charging, which shut down DC/DC stage at zero part of the charging current waveform, can greatly reduce converter loss while keeping small DC link voltage ripple. Experiment results from GaN prototype verified the concept and 39% loss saving is demonstrated.
Ballistic transport characteristic of ingaas quantum well surface channel MOSFET including effects of physical device parameter

In this paper, impact of device & process parameter variation on quantum ballistic Current-Voltage (I-V) characteristics of a surface channel, High K stack gate Quantum Well MOSFET is simulated. Physical device parameters like channel thickness, gate dielectric thickness and process parameters like doping density have direct effects on quantum ballistic current. We use mode space approach with NEGF formalism to simulate Current-Voltage (I-V) characteristics. Short Channel effects (SCE) are studied from the simulation for these variations. Observed effect is scaling dielectric & channel thickness results in better subthreshold slope & Drain induced barrier lowering at the cost of On-current. By increasing doping concentration, ballistic current can be improved. However with increasing doping density, SCE effects are compromised.
Object-Based Accumulated Motion Feature for the Compressed Domain Human Action Analysis

Generally, the object-based prominent motion features haven’t been generated to analyze the human actions in the conventional compressed domain human action analysis systems such that the human actions are identified inaccurately. Here, we apply the video segmentation method to acquire the human region in the compressed domain and then use the macroblock tracking process to trace each macroblock within the human region. Then a new motion feature called object-based accumulative motion vector (OAMV) is generated to extract the prominent motion feature for the human actions. Finally, human actions are identified by using the Hidden Markov Models.
Trade Unions and Industrial Injury in Great Britain

Anecdotal evidence suggests that trade unions succeed in ameliorating workplace health and safety, but no attempt has been made to link specific workplace injury rates with a respective union presence. Relying on WERS98, this paper establishes a cross-sectional link between trade unions and occupational injury rates, revealing that unions gravitate to accident-prone workplaces and react by reducing injury rates within these types of employment units. However, the ability for unions to reduce injury rates does not appear to increase monotonically as they progress along a workplace instrumentality continuum from recognition alone to a pre-entry closed shop.
A benchmark for spatial and temporal correlation based data prediction in wireless sensor networks

Missing data is an inevitable problem in wireless sensor network and the way missing values are handled can significantly affect the analysis results involving such data. To address data missing issues, spatial correlation and temporal correlation modeling can be applied. This paper aims at reviewing some popular spatial and temporal correlation based methods. The proposed review includes a critical overview through a summary of pros and cons of these methods and a comparison between them based on simulation results. To our best knowledge, there is no such comparative benchmarking study in the current literature.
Recycled Pulsars Discovered at High Radio Frequency

We present the timing parameters of nine pulsars discovered in a survey of intermediate Galactic latitudes at 1400 MHz with the Parkes radio telescope. Eight of these pulsars possess small pulse periods and period derivatives thought to be indicative of "recycling. " Six of the pulsars are in circular binary systems, including two with relatively massive white dwarf companions. We discuss the implications of these new systems for theories of binary formation and evolution. One long-period pulsar (J1410-7404) has a moderately weak magnetic field and an exceedingly narrow average pulse profile, similar to other recycled pulsars.
