description: The lungs are a vital organ that facilitate several physiological processes, with gas exchange arguably being the most important, as the lungs are the only organ that directly interfaces with the atmosphere to deliver oxygen into the bloodstream. It is well appreciated that the regional overlap of airflow and blood flow, termed ventilation-perfusion (V/Q) matching, is a critical determinant of gas exchange efficiency and oxygen uptake. Decades of research efforts have revealed that pulmonary anatomy and gravity are major determinants of V/Q matching. It is also appreciated that the regulatory mechanism hypoxic pulmonary vasoconstriction (HPV) can also affect significantly affect and alter V/Q matching. In response to local hypoxia in the alveolar space, corresponding upstream pulmonary arteries vasoconstrict. This action of HPV is understood to redistribute pulmonary blood flow to regions of the organ that have adequate oxygen supply. However, there are gaps in our understanding of HPV’s cellular/molecular basis and how HPV’s function is integrated into the organ to affect V/Q matching at the system-level. This thesis leverages a systems-engineering perspective and computational modeling to reveal the mechanistic basis by which (Chapter 2) V/Q matching affects oxygenation, and (Chapter 3) how HPV affects V/Q matching and oxygenation. In Chapter 4 the model is used to test how putative locations of the HPV’s oxygen sensors could redistribute blood flow and maintain oxygenation in response to a collapsed/occluded airway. These research efforts yield a new integrated understanding of how HPV is integrated within pulmonary vascular tissue and how it affects the distribution of blood flow, V/Q ratios, and oxygen uptake.

description: We prove that algebraic de Rham cohomology as a functor defined on smooth F_p-algebras is formally etale in a precise sense. This result shows that given de Rham cohomology, one automatically obtains the theory of crystalline cohomology as its unique functorial deformation. To prove this, we define and study the notion of a pointed G_a-perf-module and its refinement which we call a quasi-ideal in$G_a-perf -- following Drinfeld's terminology. Our main constructions show that there is a way to ``unwind" any pointed G_a-perf-module and define a notion of a cohomology theory for algebraic varieties. We use this machine to redefine de Rham cohomology theory and deduce its formal etalness and a few other properties.

description: Nanoparticle (NP) self-assembly is a versatile bottom-up approach to design and synthesize novel functional materials. Thermodynamics and kinetics of the self-assembly are governed by many factors, such as the shape of the nanoparticles, surface ligand, pH, salt concentration of the solution, temperature, and so on. It is not trivial to understand multiplicity of variables in the assembly behavior but is crucial for developing design principles to obtain target assemblies with desired properties. In this dissertation, I investigated the self-assembly of polyhedral NPs using Monte Carlo and molecular dynamics simulations. I focused on understanding how the shape of particles and the energetic interactions between particles affect their self-assembly behavior. In the first project, I investigated entropy-driven self-assembly of hard bipyramid systems with varying aspect ratios and symmetries. I showed that diverse colloidal superstructures with various symmetries and complexities can be obtained by tuning the shape of bipyramid particles. I found some bipyramids are mesogenic and they show different mesophase transition behavior. I demonstrated that the crystallization pathways as well as the transition behavior involving mesophases can be modulated by tuning the bipyramidal shape. In the second project, I studied DNA-mediated assembly of decahedral NPs into a dodecagonal quasicrystal in collaboration with Mirkin group at Northwestern University. I showed that the quasicrystal phase which is metastable in a hard particle system with the same particle shape can be stabilized by the enthalpic interaction between particles driven by DNA ligands. Moreover, I showed that the quasicrystal has an intrinsic stacking disorder along the 12-fold symmetry axis due to frequent phason flips, which entropically contributes to the stability of the quasicrystal. In the third project, I investigated the assembly of chiral tetrahedra into helical superstructures. Using a pair potential model representing the shape, chiral ligand, and charge interactions, I showed that the modeled tetrahedra self-assemble into 1D tetrahelices by precisely tuning the short-range attraction and long-range repulsion. I showed that the chiral bias induced by the ligand propagates to the superstructures leading to the highly enantioselective assembly of tetrahelices. Nextly, I suggested a hierarchical assembly route from tetrahedra into helical bundles via tetrahelices, which can be rationalized by the fusion of tetrahedra and subsequent charge renormalization. I expect these works provide guidance for proper selection of the building block and the assembly conditions to assemble desired nanoparticle superstructures.

description: Recently Kang et al showed that the amplitude of the light-induced-degradation effects related to the activation
under the injection of free carriers of boron-oxygen related complexes could be reduced by replacing the standard
hydrogenated silicon nitride (SiN-H) anti-reflection film by a carbon-rich SiN film deposited from polymer solid or liquid
source. In this study, we show that similar reduced-LID effects can be obtained by using standard PECVD equipments, just
by adding CH4 gas during the deposition step without altering the optical properties of the layer. The amounts of the different
species present within the film were evaluated, and the stability under outdoor conditions of the optical and electrical
properties of the dielectric was monitored.

description: In this paper we report the results of an X-ray monitoring campaign on the heavily obscured Seyfert galaxy Markarian 3 carried out between the fall of 2014 and the spring of 2015 with NuSTAR, Suzaku and XMM-Newton. The hard X-ray spectrum of Markarian 3 is variable on all the time scales probed by our campaign, down to a few days. The observed continuum variability is due to an intrinsically variable primary continuum seen in transmission through a large, but still Compton-thin column density (N_H~0.8-1.1$\times$10$^{24}$ cm$^{-2}$). If arranged in a spherical-toroidal geometry, the Compton scattering matter has an opening angle ~66 degrees and is seen at a grazing angle through its upper rim (inclination angle ~70 degrees). We report a possible occultation event during the 2014 campaign. If the torus is constituted by a system of clouds sharing the same column density, this event allows us to constrain their number (17$\pm$5) and individual column density, [~(4.9$\pm$1.5)$\times$10$^{22}$ cm$^{-2}$]. The comparison of IR and X-ray spectroscopic results with state-of-the art "torus" models suggests that at least two thirds of the X-ray obscuring gas volume might be located within the dust sublimation radius. We report also the discovery of an ionized absorber, characterised by variable resonant absorption lines due to He- and H-like iron. This discovery lends support to the idea that moderate column density absorbers could be due to clouds evaporated at the outer surface of the torus, possibly accelerated by the radiation pressure due to the central AGN emission leaking through the patchy absorber.

description: PV and wind power are the major renewable power technologies in most regions on earth. Depending on the
interaction of solar and wind resources, PV and wind power industry will become competitors or allies. Time
resolved geospatial data of global horizontal irradiation and wind speeds are used to simulate the power feed-in of PV
and wind power plants assumed to be installed on an equally rated power basis in every region of a 1°x1° mesh of
latitude and longitude between 65°N and 65°S. An overlap of PV and wind power full load hours is defined as
measure for the complementarity of both technologies and identified as ranging between 5% and 25% of total PV and
wind power feed-in. Critical overlap full load hours are introduced as a measure for energy losses that would appear
if the grid was dimensioned only for one power plant of PV or wind. In result, they do not exceed 9% of total feed-in
but are mainly around 3% - 4%. Thus the two major renewable power technologies must be characterized by
complementing each other.

description: This thesis research applied a second-order nonlinear optical spectroscopic technique with a submonolayer interface specificity, sum frequency generation (SFG) vibrational spectroscopy, to investigate a variety of solid/liquid interfaces related to biofouling and antifouling/fouling release in situ nondestructively. Molecular behavior of biological molecules, polymers, and water at buried interfaces was probed using SFG, providing important knowledge on understanding molecular mechanisms of biofouling and preventing biofouling from occurring. Biofouling is the process by which proteins, bacteria, and organisms stick to a surface. Biofouling is an important issue for a variety of fields. For example, in the maritime industry, biofouling can cause buildup of biofilms and organisms such as barnacles and mussels onto ship hulls and rudders. This fouling can cause significant increases in drag and decreases and water dynamics of the vessel, leading to increased fuel consumption and pollution. In the biomedical field, biofouling on medical implant can lead to blood clots, unnecessary immune response, infection, and rejection of implants. By understanding biofouling, researchers can better develop antifouling or fouling release coatings that can solve these problems. In this thesis, we investigated surface passivating proteins bovine casein (chapter 2) and serum albumin (chapter 3) to develop a molecular understanding of the surface passivation mechanism. Surface passivation is the process of coating a material with an initial layer of a protein that will prevent other proteins/cells from sticking to the surface. A molecular level understanding of the passivation mechanism has yet to be fully understood. In Chapter 4, we investigated barnacle xiii cement peptides (BCPs). Barnacles are a highly abundant marine foulant. Our investigation directly probed the molecular interactions of BCPs on model polymer surfaces PMMA and PS to better understand the fouling mechanism of BCPs. In Chapter 5, we investigated novel PDMS materials which have tunable surface chemistry and mechanical properties to understand the surface hydration of these materials and their potential as antifouling/fouling release materials. This research demonstrated that SFG could directly probe molecular interactions at the buried solid/liquid interfaces related to biofouling/antifouling/fouling-release.in situ in real time, providing important knowledge for developing new materials with improved antifouling/foulingrelease performance. Specifically, this thesis shows that SFG is a powerful tool for probing a variety of interfaces for biofouling applications, including protein/polymer interfaces (elucidating protein structures at interfaces) and material/water interfaces giving us insights into surface/water interactions and surface hydration.

description: We present a machine learning package for the classification of periodic variable stars. Our package is intended to be general: it can classify any single band optical light curve comprising at least a few tens of observations covering durations from weeks to years, with arbitrary time sampling. We use light curves of periodic variable stars taken from OGLE and EROS-2 to train the model. To make our classifier relatively survey-independent, it is trained on 16 features extracted from the light curves (e.g. period, skewness, Fourier amplitude ratio). The model classifies light curves into one of seven superclasses - Delta Scuti, RR Lyrae, Cepheid, Type II Cepheid, eclipsing binary, long-period variable, non-variable - as well as subclasses of these, such as ab, c, d, and e types for RR Lyraes. When trained to give only superclasses, our model achieves 0.98 for both recall and precision as measured on an independent validation dataset (on a scale of 0 to 1). When trained to give subclasses, it achieves 0.81 for both recall and precision. In order to assess classification performance of the subclass model, we applied it to the MACHO, LINEAR, and ASAS periodic variables, which gave recall/precision of 0.92/0.98, 0.89/0.96, and 0.84/0.88, respectively. We also applied the subclass model to Hipparcos periodic variable stars of many other variability types that do not exist in our training set, in order to examine how much those types degrade the classification performance of our target classes. In addition, we investigate how the performance varies with the number of data points and duration of observations. We find that recall and precision do not vary significantly if the number of data points is larger than 80 and the duration is more than a few weeks. The classifier software of the subclass model is available from the GitHub repository (https://goo.gl/xmFO6Q).

description: Integration of distributed photovoltaics (PVs) in power systems around the world has increased
substantially over the past few decades and solar power is now making significant contributions to the power supply on
some electricity markets. At many high-latitude locations, however, the level of integration is still almost negligible,
although it is likely to increase over the coming years. This paper presents the main findings from an interdisciplinary
research project that investigated the opportunities for, and consequences of, a widespread integration of distributed PVs
in the built environment in Sweden. The aspects considered were the solar energy potential at high latitudes, the
electricity balance of residential buildings with on-site PVs, the operation of distribution grids with high-penetration PVs
and the balance-keeping of the power system with large volumes of solar power. The main conclusion is that the Swedish
power system allows high penetration levels of PVs in the above respects, although the latter two areas warrant further
research. The predominant challenge is the lack of a crediting system for power overproduction from on-site PV systems.
Net metering or net billing are reasonable options. In future studies, distributed PVs as part of smart-grid solutions at the
distribution level of the power system will be studied, involving electric vehicles and end-use pricing for controlling
household electricity use. Another focus will be on how to balance large volumes of solar power in the Swedish/Nordic
power system.

description: This study explores the social complexity of the experience of growing up with an absent father. This research was motivated by two key questions: 1) How can we define absence beyond the residential status of fathers? 2) How can we understand how different types of absence lead to variation in how children internalize the experience of an absent father as adults? To answer these questions, I use the narratives and life histories as told by 35 low-income black men from Southeastern Michigan. I first argue that absence is a variegated experience that requires going beyond the residential status of the father to designate a father as absent. To begin, I introduce a typology of absence that contains four distinct patterns that effectively contextualize how respondents experienced absence during their childhood. I developed an absence scoring schema to better compare respondents and account for the different sequencing and durations of patterns they experienced during their childhood. Using this absence scoring schema, I explored how one’s location in the absence score spectrum influenced how men: 1) constructed knowledge of who their father was, and 2) constructed strategies to be better or more present than their fathers in the lives of their future children. First, I discovered was men who experienced less extreme absence had knowledge of their father and strategies for fatherhood based on first-hand experiences and interactions. Those who experienced more extreme absence had knowledge of their father and strategies based on second-hand knowledge and assumptions about their father. Last, this research introduces the idea of an “ecology of absence” that considers the influence of the communal pervasiveness of absence that all my respondents experienced. Previous cultural sociology research on this population has only examined the influence of the “culture of poverty”. This final piece of the research used a network analysis to demonstrate absence as a pervasive social reality among many in each respondent’s social networks. I further demonstrate how this “ecology of absence” correlates to a disassociation of fathering from partnering, where men did not see being together with the mother of their child as necessary for being the fathers they intended to be. This research expands our definition of absence and its influence on individuals and has implications for how researchers and policymakers define fathers as absent and how we encourage father involvement. Additionally, this research introduces absence an alternative mode of cultural inquiry into the lives of marginalized black men, which to-date, has been limited to the cultural influence of poverty

description: The aggressive scaling of silicon-based nanoelectronics has reached the regime where device function is affected not only by the presence of individual dopants, but more critically their position in the structure. The quantitative determination of the positions of subsurface dopant atoms is an important issue in a range of applications from channel doping in ultra-scaled transistors to quantum information processing, and hence poses a significant challenge. Here, we establish a metrology combining low-temperature scanning tunnelling microscopy (STM) imaging and a comprehensive quantum treatment of the dopant-STM system to pin-point the exact lattice-site location of sub-surface dopants in silicon. The technique is underpinned by the observation that STM images of sub surface dopants typically contain many atomic-sized features in ordered patterns, which are highly sensitive to the details of the STM tip orbital and the absolute lattice-site position of the dopant atom itself. We demonstrate the technique on two types of dopant samples in silicon -- the first where phosphorus dopants are placed with high precision, and a second containing randomly placed arsenic dopants. Based on the quantitative agreement between STM measurements and multi-million-atom calculations, the precise lattice site of these dopants is determined, demonstrating that the metrology works to depths of about 36 lattice planes. The ability to uniquely determine the exact positions of sub-surface dopants down to depths of 5 nm will provide critical knowledge in the design and optimisation of nanoscale devices for both classical and quantum computing applications.

description: Recommender systems (RSs) provide an effective way of alleviating the information overload problem by selecting personalized choices. Online social networks and user-generated content provide diverse sources for recommendation beyond ratings, which present opportunities as well as challenges for traditional RSs. Although social matrix factorization (Social MF) can integrate ratings with social relations and topic matrix factorization can integrate ratings with item reviews, both of them ignore some useful information. In this paper, we investigate the effective data fusion by combining the two approaches, in two steps. First, we extend Social MF to exploit the graph structure of neighbors. Second, we propose a novel framework MR3 to jointly model these three types of information effectively for rating prediction by aligning latent factors and hidden topics. We achieve more accurate rating prediction on two real-life datasets. Furthermore, we measure the contribution of each data source to the proposed framework.

description: We propose a new unbiased threshold for network analysis named the Cluster-Span Threshold (CST). This is based on the clustering coefficient, C, following logic that a balance of `clustering' to `spanning' triples results in a useful topology for network analysis and that the product of complementing properties has a unique value only when perfectly balanced. We threshold networks by fixing C at this balanced value, rather than fixing connection density at an arbitrary value, as has been the trend. We compare results from an electroencephalogram data set of volunteers performing visual short term memory tasks of the CST alongside other thresholds, including maximum spanning trees. We find that the CST holds as a sensitive threshold for distinguishing differences in the functional connectivity between tasks. This provides a sensitive and objective method for setting a threshold on weighted complete networks which may prove influential on the future of functional connectivity research.

description: This article summarizes the main results obtained by the investigation of annealing and degradation
mechanisms observed for amorphous silicon (a-Si) modules. This interest comes from the encouraging results
obtained by thermally insulated a-Si PV plant. Findings showed that the better thermal behaviour and annealing
processes of a-Si compared to c-Si technologies compensated a significant part of losses due to the nearly horizontal
roof integration.
The study focuses on the characterization of the annealing process, in terms of temperature and heating duration.
Other aspects investigated are the stability of annealing and stability of degradation, the degradation dependence on
the module load and the contrasting effects occurring to a-Si module power due to a temperature increase.

is the flasher test on a subset of individual PV modules. This is typically performed by several experienced
independent test labs and requires quite an effort both in logistics and time. The recently developed Swiss Mobile
Flasher Bus, equipped with a standard high-quality PASAN flasher, comes to the customer’s site and can test a
higher number of samples at approximately the same cost as the above-mentioned practice for more than 20 samples
per order. The measurement results are available just in time. Standard STC power measurements were performed
with a 10ms flasher pulse on polycrystalline silicon modules with less than 1% deviation to the results on the same
samples performed at Fraunhofer ISE. The same close match of +/- 1% was found when HIT-type silicon PV
modules where tested by applying the multi-flasher mode with an overall pulse duration of 120ms. Thin-film a-Si/uc-
Si, CIS and CdTe modules were also successfully tested in comparison to reference measurements on the same
samples by other well-known labs. Efficiency measurement at low irradiance levels is also available as a standard
method. Other measurement methods like spectral photocurrent measurement and temperature coefficient
measurement will be added to the standard functionality of the Swiss Mobile Flasher Bus within the next months.

description: We report on an exploratory lattice study on the phenomenon of chiral instabilities in non-Abelian gauge theories at high temperature. It is based on a recently constructed anomalous Langevin-type effective theory of classical soft gauge fields in the presence of a chiral number density $n_5=n_{\rm R}-n_{\rm L}$. Evaluated in thermal equilibrium using classical lattice techniques it reveals that the fluctuating soft fields indeed exhibit a rapid energy increase at early times and we observe a clear dependence of the diffusion rate of topological charge (sphaleron rate) on the the initial $n_5$, relevant in both early universe baryogenesis and relativistic heavy-ion collisions. The topological charge furthermore shows a drift among distinct vacuum sectors, roughly proportional to the initial $n_5$ and in turn the chiral imbalance is monotonously reduced as required by helicity conservation.

description: A powerful tool for quickly assessing the available markets for a proposed concentrator photovoltaic
system was created. If an estimate for the total system cost exists, the enclosed diagram can be used to discover the
range of solar resources and minimum electricity price or feed-in tariff necessary to meet economic targets. Areas
throughout the world and within specified ranges of annual direct normal solar resources are presented, providing
initial insight into the regional location of potential markets. The method outlined and resources identified in this
paper should serve as a starting point for those interested in designing and developing concentrator photovoltaic
systems. The cost targets may be especially interesting for those working with parabolic trough technologies.

description: Incident reporting systems (IRSs) are among the most widespread safety improvement strategies for managing, learning from, and preventing the recurrence of serious-safety-events as well near-misses in healthcare. Nevertheless, national rates of patient safety incident underreporting are estimated to be as high as 86 – 95%. Underreporting disguises critical knowledge and safety gaps, leads to the misallocation of quality improvement resources, limits organizational learning, and ultimately perpetuates the recurrence of one of the most egregious adverse events in healthcare that, by definition, should never occur – retained surgical items (RSIs). Perioperative nurses (RNs) play the central role in reporting surgical count related errors like RSIs and their near-miss precursor safety events known as incorrect surgical counts. However, much work remains needed to understand and address the challenges associated with reporting these events known to have potential for catastrophic harm. Although interventions have been applied to improve incident reporting among healthcare professionals in general, systematic reviews highlight that the vast majority have not been guided by theory and that none have focused on the context of surgery or the problem of surgical count error underreporting. This mixed-methods study therefore aims to fill a gap in the literature by i) analyzing the prevalence of- and factors associated with underreporting of surgical count related errors (Aim 1), ii) applying behavioral theories to identify the determinants of surgical count error reporting among perioperative RNs (Aim 2), and iii) systematically integrating learning health systems and implementation science strategies to design targeted interventions that address underreporting (Aim 3). The results of this research present a novel and theory-grounded approach towards understanding and addressing the range of organizational, environmental, and individual-level barriers to patient safety incident reporting in surgery and should be used to inform future work on enhancing the effectiveness of incident reporting systems as well as provider engagement in the reporting process.

description: Nowadays, generally the PV systems based on thin films technologies (TF-Si, CdTe, CIGS) are not
really differentiated by applications and we can see that all technologies are used for all segments (solar farms,
commercial roofs and residential ones) with different shares. The competitiveness of the various PV technologies is
studied in this paper based on the Levelized Cost of Electricity (LCOE) for the scope of applications in several sites.
The LCOE is calculated following all the value chain (raw materials and production equipments for modules, split
BOS, installation, energy yield, degradation and financing). The modules production cost breakdown is first
quantified showing the weight of investment amortization, the base components (precursors, substrates, encapsulant,
energy) and the industrial yield if not controlled; industrial building and manpower have a light influence. In the
integration of the PV module into the PV system, the costs of BOS elements are leveraged by the efficiency of the
module for the three main applications. The assumptions of iso-power (fixed power) or iso-surface (limited surface)
have an impact on costs.
Operated at different locations, the production yield takes into account the physical performances of each technology
with some variations and the meteorological conditions and has an impact up to 10% on final amount of energy
produced. Final LCOE values are achieved by adding system lifetime, efficiency degradation and expected
investment return rate (IRR).
Introducing the LCOE data for advanced and traditional crystalline silicon technologies, by analyzing the output, we
can notice that all technologies are within a small range (+/- 8%) except single junction amorphous silicon which is
too penalized on BOS by a low efficiency currently. Depending of the applications, the order of competitiveness for
the various thin films and Si crystalline changes but still within a small +/-8% corridor on the next 10 years forecast.
In such dynamic market, at the scale of the decade, finally, the progress speed (innovation, time to market, capacity
increase) is much stronger than any parameters at a given moment and so the capability to improve from a year to the
other is really the key of a sustainable competitiveness.
Absorption at 11 microns in the interstellar medium and embedded sources: evidence for crystalline silicates

description: An absorption feature is occasionally reported around 11 microns in astronomical spectra, including those of forming stars. Candidate carriers include water ice, polycyclic aromatic hydrocarbons (PAHs), silicon carbide, crystalline silicates or even carbonates. All are known constituents of cosmic dust in one or more types of environments, though not necessarily together. In this paper we present new ground-based 8-13 micron spectra of one evolved star, several embedded young stellar objects (YSOs) and a background source lying behind a large column of the interstellar medium (ISM) toward the Galactic Centre. Our observations, obtained at a spectral resolution of approximately 100, are compared with previous lower resolution data, as well as data obtained with the Infrared Space Observatory (ISO) on these and other targets. By presenting a subset of a larger sample our aim is to establish the reality of the feature and subsequently speculate on its carrier. All evidence points toward crystalline silicate. For instance, the 11 micron band profile is well matched with the emissivity of crystalline olivine. Furthermore, the apparent association of the absorption feature with a sharp polarisation signature in the spectrum of two previously reported cases suggests a carrier with a relatively high band strength compared to amorphous silicates. If true, this would either set back the evolutionary stage in which silicates are crystallised, either to the embedded phase or even before within the ISM, or else the silicates ejected from the outflows of evolved stars retain some of their crystalline identity during their long residence in the ISM.

description: The Spanish government has published a new regulatory framework for the electricity generation with
photovoltaic technology. This framework is the new Royal Decree 1565/2010, dated 19th November, intended to
amend certain aspects of the electricity generation activity under the so called special regime, introducing new
measures affecting the generation and the legal requirements both during operation of existing plants as for the launch
of new facilities. This Royal Decree also establishes a change of the feed in tariff for the sale of photovoltaic energy.
The new Royal Decree-Law 14/2010, dated 23rd December, establishing urgent measures to correct the tariff deficit
in the electricity sector, which directly affect the economic returns of photovoltaic energy production, introducing a
limit to the equivalent operating hours of photovoltaic installations entitled to a regulated tariff and including an
extension of the number of years with entitlement to this feed in tariff.
In this paper, this new regulatory landscape is analyzed from an economic point of view. Also a study of trend prices
in terms of economies of scale production of photovoltaic modules is performed. Both studies establish a hypothesis
of cost effectiveness studies for installation of photovoltaic plants in Spain with the aim of establishing the necessary
conditions to achieve grid-parity.
