description: In recent years, our group has developed a comprehensive cardiopulmonary (CP) model that comprises the heart, systemic and pulmonary circulations, lung mechanics and gas exchange, tissue metabolism, and cardiovascular and respiratory control mechanisms. In this paper, we analyze the response of the model to hypercapnic conditions and hence focus on the chemoreflex control mechanism. Particularly, we have enhanced the peripheral chemoreceptor model in order to better reflect respiratory control physiology. Using the CO2 fraction in the inspired air as input to the CP model, we were able to analyze the transient response of the system to CO2 step input at different levels, in terms of alveolar gas partial pressures, tidal volume, minute ventilation and respiratory frequency. Model predictions were tested against experimental data from human subjects. Results show good agreement for all the variables under study during the transient phases and low root mean square errors at steady state. This indicates the potential for the model to be used as a valid tool for clinical practice and medical research, providing a complementary way to experience-based clinical decisions.
Algebraic decay of the survival probability in chaotic helium

description: We demonstrate that the classical helium atom exhibits algebraic decay of the survival probability in the autoionizing {\it eZe} configuration. Excitation towards asymptotic orbits of marginal stability is identified as the cause of the nonexponential decay. Since one electron travels along a bound Kepler trajectory of infinite excitation in these orbits, we argue that the classical decay law will prevail in the quantum dynamics of a wave packet launched along the {\it eZe} configuration.

description: This study uses r-band images from the Eighth Data Release of the Sloan Digital Sky Survey (SDSS DR8) to study bars in lenticular (S0) galaxies in one of the nearest rich cluster environments, the Coma cluster. We develop techniques for bar detection, and assess their success when applied to SDSS image data. To detect and characterise bars we perform 2D bulge+disk+bar light decompositions of galaxy images with GALFIT. Using a sample of artificial galaxy images we determine the faintest magnitude at which bars can be successfully measured at the depth and resolution of SDSS. We perform detailed decompositions of 83 S0 galaxies in Coma, 64 from a central sample, and 19 from a cluster outskirts sample. For the central sample, the S0 bar fraction is 72^{+5}_{-6}%. This value is significantly higher than that obtained using an ellipse fitting method for bar detection, 48^{+6}_{-6}%. At a fixed luminosity, barred S0s are redder in (g-r) colour than unbarred S0s by 0.02 mag. The frequency and strength of bars increase towards fainter luminosities. Neither central metallicity nor stellar age distributions differ significantly between barred and unbarred S0s. There is an increase in the bar fraction towards the cluster core, but this is at a low significance level. Bars have at most a weak correlation with cluster-centric radius.

description: Companion planting of White clover (Trifolium repens L. WC) and orchard grass (Dactylis glomerata L. OG), as a famous hay grass has been widely reported to improve forage quality of OG. Microbiome profiling techniques provide us another approach to reveal the specific role of WC and OG during companion planting. Exploring the variety of microbiome distribution of OG 1) with or without companion plating; 2) in rhizosphere and non-rhizosphere soil environment will help us recognize the local and distant effects of companion planting on microbiome profiles and in return, the mechanisms of the altered microbiome's effects on grass planting. Relied on metagenomics sequencing, we confirmed the irreplaceable role of WC on soil environment modeling during companion planting. New functional flora for companion planting were also revealed. The underlying biological mechanisms for plant quality modification during companion planting have been attributed to nitrogen and carbon fixation. All in all, our study recognized specific rhizosphere effects, typical biomarker flora and potential regulatory mechanisms for WC related companion planting via metagenomics analyses.

description: We study the properties of waves in a facular region of moderate strength in the photosphere and chromosphere. Our aim is to analyse statistically the wave periods, power and phase relations as a function of the magnetic field strength and inclination. Our work is based on observations obtained at the German Vacuum Tower Telescope (Observatorio del Teide, Tenerife) using two different instruments: the Triple Etalon SOlar Spectrometer (TESOS), in the BaII 4554 A line to measure velocity and intensity variations through the photosphere; and, simultaneously, the Tenerife Infrared Polarimeter (TIP-II), in the FeI 1.56 mm lines to the measure the Stokes parameters and magnetic field strength in the lower photosphere. Additionally, we use the simultaneous broad-band filtergrams in the CaIIH line to obtain information about intensity oscillations in the chromosphere. We find several clear trends in the oscillation behaviour: (i) the period of oscillation increases by 15-20 % with the magnetic field increasing from 500 to 1500 G; (ii) the temperature-velocity phase shifts show a strikingly different distribution in the facular region compared to the quiet region, a significant number of cases in the range from -180 to 180 degrees is detected in the facula. (iii) the most powerful chromospheric CaIIH intensity oscillations are observed at locations with strong magnetic fields (1.3-1.5 kG) inclined by 10-12 degrees, as a result of upward propagating waves with rather small phase speeds, and temperature-velocity phase shifts between 0 and 90 degrees; (iv) the power of the photospheric velocity oscillations from the \BaII\ line increases linearly with decreasing magnetic field inclination, reaching its maximum at strong field locations.

description: Educating the users on the essential of information security is very vital and important to the mission of establishing a sustainable information security in any organization and institute. At the University Technology Malaysia (UTM), we have recognized the fact that, it is about time information security should no longer be a lacking factor in productivity, both information security and productivity must work together in closed proximity. We have recently implemented a broad campus information security awareness program to educate faculty member, staff, students and non-academic staff on this essential topic of information security. The program consists of training based on web, personal or individual training with a specific monthly topic, campus campaigns, guest speakers and direct presentations to specialized groups. The goal and the objective are to educate the users on the challenges that are specific to information security and to create total awareness that will change the perceptions of people thinking and ultimately their reactions when it comes to information security. In this paper, we explain how we created and implemented our information security awareness training (ISAT) program and discuss the impediment we encountered along the process. We explore different methods of deliveries such as target audiences, and probably the contents as we believe might be vital to a successful information security program. Finally, we discuss the importance and the flexibility of establishing a sustainable information security training program that could be adopted to meet current and future needs and demands while still relevant to our current users.

description: We study the influence of a tunnel barrier on the quantum transport through a circular cavity. Our analysis in terms of classical trajectories shows that the semiclassical approaches developed for ballistic transport can be adapted to deal with the case where tunneling is present. Peaks in the Fourier transform of the energy-dependent transmission and reflection spectra exhibit a nonmonotonic behaviour as a function of the barrier height in the quantum mechanical numerical calculations. Semiclassical analysis provides a simple qualitative explanation of this behaviour, as well as a quantitative agreement with the exact calculations. The experimental relevance of the classical trajectories in mesoscopic and microwave systems is discussed.

description: This dispute over the boundaries of labor and the effects of work on the laboring body is symptomatic of the difficulty of establishing a shared vision of what the focus of a politics of labor could and should be. This is not merely a matter of academic debate, of course; reflecting the emotional commitments that sustain a wide range of conceptual, empirical, and organizational activities, the intensity of the exchange also reminds us that the idioms we employ become part of how we relate and, perhaps more importantly, what modes of relation, cooperation, and solidarity we are able to envision. We invoke the conflictual subject of labor here, however, to highlight the need to explore the machinic capture of value through logistical infrastructures, cooling the anger of miscommunication to fuel the cold wrath of a different politics of labor.

Our babies: child multiples and the American imaginary, 1934-1960

description: From 1934-1960, nearly twenty sets of triplets, quadruplets and quintuplets graced the pages of newspapers, magazines, scrapbooks, family photo albums and baby books throughout the United States. This project explores the cultural forces at work that allowed for such intense collective interest and investment in child multiple sensations in mid-century America, with a focus on two particular sets: The Dionne Quintuplets and the Fultz Quadruplets. In conversation with recent scholarship from the history of childhood, history of medicine, African American studies and cultural studies, I argue that the spectacle of the Dionnes and Fultzes shaped visions of national and racial belonging and ideas about child health and well-being in mid-twentieth century America. Further, the social and cultural spaces they occupied offer historians critical insights about the way ideas about childhood have been crafted and sustained. This project employs archival research methods using sources such as historical newspaper and magazine articles, photo essays and advertisements; corporate advertising records; public health material; and publicity materials. In addition, I use a range of items of material culture, such as scrapbooks, photo albums, and other ephemera. This research offers an opportunity to explore what is historically mapped onto the figure of the child and the ways in which childhood, as a construct, has operated as a carrier of an enormous range of social and cultural meanings and ideological investments.

description: The semiclassical quantization of classically stable planetary atom configurations (the so called frozen planet configurations) is discussed in some detail. The existence of (approximate) integrals of motion allows for a torus quantization procedure, the semiclassical limit of which is the Gutzwiller periodic orbit formula reduced to fundamental orbits only. We show that the multi-dimensional torus quantization yields accurate semiclassical energies for the planetary atom states. We compare our results with those obtained by a multipole model of the electron- electron interaction which has been proposed as a more transparent model for describing the frozen planet configurations. We give evidence that this model fails in predicting the energies for large quantum numbers.

description: Source separation or demixing is the process of extracting multiple components entangled within a signal. Contemporary signal processing presents a host of difficult source separation problems, from interference cancellation to background subtraction, blind deconvolution, and even dictionary learning. Despite the recent progress in each of these applications, advances in high-throughput sensor technology place demixing algorithms under pressure to accommodate extremely high-dimensional signals, separate an ever larger number of sources, and cope with more sophisticated signal and mixing models. These difficulties are exacerbated by the need for real-time action in automated decision-making systems. Recent advances in convex optimization provide a simple framework for efficiently solving numerous difficult demixing problems. This article provides an overview of the emerging field, explains the theory that governs the underlying procedures, and surveys algorithms that solve them efficiently. We aim to equip practitioners with a toolkit for constructing their own demixing algorithms that work, as well as concrete intuition for why they work.

description: Rates of lung cancer in American men have greatly exceeded those in Japanese men for several decades despite the higher smoking prevalence in Japanese men. It is not known whether the relative risk of lung cancer associated with cigarette smoking is lower in Japanese men than American men and whether these risks vary by the amount and duration of smoking. To estimate smoking-specific relative risks for lung cancer in men, a multicentric case-control study was carried out in New York City, Washington, DC, and Nagoya, Japan from 1992 to 1998. A total of 371 cases and 373 age-matched controls were interviewed in United States hospitals and 410 cases and 252 hospital controls in Japanese hospitals; 411 Japanese age-matched healthy controls were also randomly selected from electoral rolls. The odds ratio (OR) for lung cancer in current United States smokers relative to nonsmokers was 40.4 [95% confidence interval (CI) = 21.8-79.6], which was >10 times higher than the OR of 3.5 for current smokers in Japanese relative to hospital controls (95% CI = 1.6-7.5) and six times higher than in Japanese relative to community controls (OR = 6.3; 95% CI = 3.7-10.9). There were no substantial differences in the mean number of years of smoking or average daily number of cigarettes smoked between United States and Japanese cases or between United States and Japanese controls, but American cases began smoking on average 2.5 years earlier than Japanese cases. The risk of lung cancer associated with cigarette smoking was substantially higher in United States than in Japanese males, consistent with population-based statistics on smoking prevalence and lung cancer incidence. Possible explanations for this difference in risk include a more toxic cigarette formulation of American manufactured cigarettes as evidenced by higher concentrations of tobacco-specific nitrosamines in both tobacco and mainstream smoke, the much wider use of activated charcoal in the filters of Japanese than in American cigarettes, as well as documented differences in genetic susceptibility and lifestyle factors other than smoking.

Within our approach the oscillatory parts of the diagonal and Hall conductivity are given as sums over contributions from classical periodic orbits in close relation to Gutzwiller's trace formula for the density of states. Taking into account the effects of weak disorder and temperature, we reproduce recently observed anomalous phase coherence oscillations in the conductivity of large antidot arrays.

description: We present a highly reliable and efficient mid-infrared colour-based selection technique for luminous active galactic nuclei (AGN) using the Wide-field Infrared Survey Explorer (WISE) survey. Our technique is designed to identify objects with red mid-infrared power-law spectral energy distributions. We studied the dependency of our mid-infrared selection on the AGN intrinsic luminosity and the effectiveness of our technique to uncover obscured AGN missed in X-ray surveys. To do so we used two samples of luminous AGN independently selected in hard X-ray and optical surveys. We used the largest catalogue of 887 [OIII]5007-selected type 2 quasars (QSO2s) at z<0.83 in the literature from the Sloan Digital Sky Survey (SDSS), and the 258 hard (>4.5 keV) X-ray-selected AGN from the Bright Ultrahard XMM-Newton Survey (BUXS). The effectiveness of our mid-infrared selection technique increases with the AGN luminosity. At high luminosities and at least up to z~1 our technique is very effective at identifying both Compton-thin and Compton-thick AGN.

description: Two major processes have been proposed to convert the coronal magnetic energy into the kinetic energy of a coronal mass ejection (CME): resistive magnetic reconnection and ideal macroscopic magnetohydrodynamic instability of magnetic flux rope. However, it remains elusive whether both processes play a comparable role or one of them prevails during a particular eruption. To shed light on this issue, we carefully studied energetic but flareless CMEs, \textit{i.e.}, fast CMEs not accompanied by any flares. Through searching the Coordinated Data Analysis Workshops (CDAW) database of CMEs observed in Solar Cycle 23, we found 13 such events with speeds larger than 1000 km s$^{-1}$. Other common observational features of these events are: (1) none of them originated in active regions; they were associated with eruptions of well-developed long filaments in quiet-Sun regions, (2) no apparent enhancement of flare emissions was present in soft X-ray, EUV and microwave data. Further studies of two events reveal that (1) the reconnection electric fields, as inferred from the product of the separation speed of post-eruption ribbons and the photospheric magnetic field measurement, were in general weak; (2) the period with a measurable reconnection electric field is considerably shorter than the total filament-CME acceleration time. These observations indicate that, for these fast CMEs, the magnetic energy was released mainly via the ideal flux rope instability through the work done by the large scale Lorentz force acting on the rope currents rather than via magnetic reconnections. We also suggest that reconnections play a less important role in accelerating CMEs in quiet Sun regions of weak magnetic field than those in active regions of strong magnetic field.

Ryszard Kapuściński and the Borders of Documentarism: Toward Exposure without Assumption
Creators: name: Zehle, Soenke
Publisher: name: Zenodo
Year: 2011
Subjects: documentary aesthetics

description: Even if we grant that contemporary literary journalism has many fathers and mothers, Ryszard Kapuściński was surely one of its most influential representatives. Aware of the way in which the technologies of reportage affect, structure, and transform our attentiveness to events, the Polish writer remained seemingly old-fashioned in his vision of journalism as a creative craft independent of the tyranny of real-time news and the “house styles” assumed to define and limit the expectations of established news audiences. His engaged work frequently crosses the borders of journalism understood in a narrowly documentarist sense. It is celebrated by some as an essayism successfully venturing beyond the stale realism of social advocacy, and criticized by others as an arrogant will to literariness and an abdication of authorial responsibility. These contradictions in his work offer a way to engage the practice of literary journalism in terms of an ethics of the encounter - an ethics sketched by the writer himself in his exploration of philosophies of otherness.

description: Information sharing in organization has been considered as an important approach in increasing organizational efficiency, performance and decision making. With the present and advances in information and communication technology, sharing information and exchanging of data across organizations has become more feasible in organization. However, information sharing has been a complex task over the years and identifying factors that influence information sharing across organization has becomes crucial and critical. Researchers have taken several methods and approaches to resolve problems in information sharing at all levels without a lasting solution, as sharing is best understood as a practice that reflects behavior, social, economic, legal and technological influences. Due to the limitation of the conventional ISM3 standards to address culture, social, legislation and human behavior, the findings in this paper suggest that, a centralized information structure without human practice, distribution of information and coordination is not effective. This paper reviews the previous information sharing research, outlines the factors affecting information sharing and the different practices needed to improve the management of information security by recommending several combinations of information security and coordination mechanism for reducing uncertainty during sharing of information .This thesis proposes information security management protocol (ISMP) as an enhancement towards ISM3 to resolve the above problems. This protocol provides a means for practitioners to identify key factors involved in successful information sharing.....
Documenting Depletion: Of Algorithmic Machines, Experience Streams, and Plastic People
Creators: name: Zehle, Soenke
Publisher: name: Zenodo
Year: 2014

description: Depletion is where the common begins, in sites to which no one lays claims anymore because they have been exhausted. Exhaustion leaves fragments, ruins, waste, it is what comes after production, after use, after work. For McKenzie Wark, the “semantic glue” needed to create “a new imaginary, a new space for thought and action” needs to be plausible rather than radical, “a popular poetics of the open totality.” What is needed is “a kind of low theory, which is no more than a creole language for negotiating different ways of living and producing knowledge . . . to think the scale-free mesh.” And for that, “we need new ancestors. The old ones, in art and theory, have been exhausted and are exhausting us.” Depletion offers a way to map a terrain, to delineate a horizon from within which to articulate a politics of depletion. Traversing an open semantic field to sketch a cartography of the political, the use of depletion as a shifting vantage point to survey sites and situations of physical and psycho-social exhaustion opens up new modes of relation, suggesting that we translate shared (semantic) properties into technologies of the common as we connect the exhaustion of resources to the depression that follows the cellularization of the work day and the work of the soul. Moved by the spirit of chance constellations and an aesthetics of aggregation, the essay explores exhaustion as if we were to construct a traverse network, choosing the next vantage point upon arrival.

description: Respondent-driven sampling (RDS) is very useful in collecting data from individuals in hidden populations, where a sampling frame does not exist. It starts with researchers choosing initial respondents from a group which may be involved in taboo or illegal activities, after which they recruit other peers who belong to the same group. Analysis results in unbiased estimates of population proportions though with strong assumptions about the underlying social network and RDS recruitment process. These assumptions bear little resemblance to reality, and thus compromise the estimation of any means, population proportions or variances inferred from studies. The topology of the contact network, denoted by the number of links each person has, provides insight into the processes of infectious disease spread. The overall objective of the thesis is to identify the topology of an injection drug use network, and critically review the methods developed to produce estimates. The topology of people who inject drugs (PWID) collected by RDS in Ottawa, 2006 was compared with a Poisson distribution, an exponential distribution, a power-law distribution, and a lognormal distribution. The contact distribution was then evaluated against a small-world network characterized by high clustering and low average distances between individuals. Last a systematic review of the methods used to produce RDS mean and variance estimates was conducted. The Poisson distribution, a type of random distribution, was not an appropriate fit for PWID network. However, the PWID network can be classified as a small world network organised with many connections and short distances between people. Prevention of transmission in such networks should be focussed on the most active people (clustered individuals and hubs) as intervention with any others is less effective. The systematic review contained 32 articles which included the development and evaluation of 12 RDS mean and 6 variance estimators. Overall, the majority of estimators perform roughly the same, with the exception of RDSIEGO which outperformed the 6 other RDS mean estimators. The Tree bootstrap variance estimate does not rely on modelling RDS as a first order Markov (FOM) process, which seems to be the main limitation of the other existing estimators. The lack of FOM as an assumption and the flexible application of this variance estimator to any RDS point estimate make the Tree bootstrapping estimator a more efficient choice.

Using the self-consistent density functional theory - dynamical mean field theory (DFT-DMFT) with continuous time quantum Monte Carlo (CTQMC), we find that there is greatly enhanced coupling between some correlated electron states and the A1g lattice distortion. Superconductivity in FeSe shows a very strong sensitivity to pressure, with an increase in Tc of almost a factor of 5 within a few GPa, followed by a drop, despite monotonic pressure dependence of almost all electronic properties. We find that the maximum A1g deformation potential behaves similar to the experimental Tc. In contrast, the maximum deformation potential in DFT for this mode increases monotonically with increasing pressure.

description: Polarized light microscopy provides unique opportunities for analyzing the molecular order in man-made and natural materials, including biological structures inside living cells, tissues, and whole organisms. 20 years ago, the LC-PolScope was introduced as a modern version of the traditional polarizing microscope enhanced by liquid crystal devices for the control of polarization, and by electronic imaging and digital image processing for fast and comprehensive image acquisition and analysis. The LC- PolScope is commonly used for birefringence imaging, analyzing the spatial and temporal variations of the differential phase delay in ordered and transparent materials. Here we describe an alternative use of the LC-PolScope for imaging the polarization dependent transmittance of dichroic materials. We explain the minor changes needed to convert the instrument between the two imaging modes, discuss the relationship between the quantities measured with either instrument, and touch on the physical connection between refractive index, birefringence, transmittance, diattenuation, and dichroism.

description: We report experimental and theoretical studies of edge magnetoplasmon (EMP) transport in quantum Hall (QH) devices. We develop a model that allows us to calculate the transport coefficients of EMPs in QH devices with various geometries. In our model, a QH system is described as a chiral distributed-element (CDE) circuit, where the effects of Coulomb interaction are represented by an electrochemical capacitance distributed along unidirectional transmission lines. We measure the EMP transport coefficients through single- and coupled-edge channels, a quantum point contact, and single- and double-cavity structures. These measured transmission spectra can be reproduced well by simulations using the corresponding CDE circuits. By fitting the experimental results with the simulations, we deduce the circuit parameters that characterize the electrostatic environment around the edge channels in a realistic QH system. The observed gate-voltage dependences of the EMP transport properties in gate-defined structures are explained in terms of the gate tuning of the circuit parameters in CDE circuits.

description: Despite the success of many advanced tracking methods in this area, tracking targets with drastic variation of appearance such as deformation, view change and partial occlusion in video sequences is still a challenge in practical applications. In this letter, we take these serious tracking problems into account simultaneously, proposing a dynamic graph based model to track object and its deformable parts at multiple resolutions. The method introduces well learned structural object detection models into object tracking applications as prior knowledge to deal with deformation and view change. Meanwhile, it explicitly formulates partial occlusion by integrating spatial potentials and temporal potentials with an unparameterized occlusion handling mechanism in the dynamic conditional random field framework. Empirical results demonstrate that the method outperforms state-of-the-art trackers on different challenging video sequences.

Exploring Distribution as a Condition: Elements of a Minor Metropolitanism

description: Urban design has long foregrounded the visual in the mise-en-scene of experience, from the sites of sovereignty to the street as stage for the collaborative constitution of urban multitudes. Reflecting on media architectures from within the horizon of contemporary processes of informatization, this essay takes as its point of departure the ways in which ambient media is woven into the fabric of the everyday, in terms the need to analytically grasp this distribution as a condition (Hansen 2015). To the extent that it engages with this condition, media architecture research moves beyond the visual and its attendant socio-technological ensembles to explore the material conditions of possibility that frame everyday experience. Many of these developments are rooted in “imperial infrastructures” that cut across sovereign territories and establish shared frames of reference and responsibility, of imagination and intervention. At the same time, they occur across a wide variety of sites that are difcult to comprehend in relation to specific models of urbanization. In the spirit of an ecology of practice open to transfer and translation, the essay therefore proceeds provisionally, making the case for a minor metropolitanism attentive to the limited reach of analytical approaches and political propositions.

description: With the exception of Terzan 5, all the Galactic globular clusters that possess significant metallicity spreads, such as omega Cen and M22, are preferentially the more luminous clusters with extended horizontal branches. Here we present radial velocities and chemical abundances for seven bright giants in the globular cluster M62, a previously little-studied cluster. With M_V = -9.18, M62 is the ninth most luminous Galactic globular cluster and has an extended horizontal branch. Within our sample, we find (i) no evidence for a dispersion in metallicity, [Fe/H], beyond the measurement uncertainties, (ii) star-to-star abundance variations for C, O, Na and Al with the usual correlations between these elements as seen in other globular clusters, and (iii) a global enrichment for the elements Zr, Ba and La at the level [X/Fe] = +0.4 dex. For elements heavier than La, the abundance ratios are consistent with the scaled-solar $r$-process distribution. Below La, the abundances are anomalous when compared to the scaled-solar s-process or r-process distributions. For these elements, the abundance signature in M62 is in agreement with predictions of the s-process from fast-rotating massive stars, although the high [Rb/Y] ratio we measure may be a challenge to this scenario.

description: The p53 transcription factor coordinates wide-ranging responses to stress that contribute to its function as a tumour suppressor. The responses to p53 induction are complex and range from mediating the elimination of stressed or damaged cells to promoting survival and repair. These activities of p53 can modulate tumour development but may also play a role in pathological responses to stress such as tissue damage and repair. Using a p53 reporter mouse, we have previously detected strong induction of p53 activity in the liver of mice treated with the hepatotoxin carbon tetrachloride (CCl4). Here, we show that p53 functions to support repair and recovery from CCl4-mediated liver damage, control reactive oxygen species (ROS) and limit the development of hepatocellular carcinoma (HCC), in part through the activation of a detoxification cytochrome P450, CYP2A5 (CYP2A6 in humans). Our work demonstrates an important role for p53-mediated redox control in facilitating the hepatic regenerative response after damage and identifies CYP2A5/CYP2A6 as a mediator of this pathway with potential prognostic utility in human HCC.
