description: We implemented the inverse design method to build a thin near-field lens that could produce a desired subwavelength focus by manipulating the near fields of a magnetic dipole source. The flat near-field lens represented by an artificial impedance surface was fabricated by lumped reactive elements (capacitor and inductor) with spatially varying values. In the experiment a desired annular focusing spot with a characteristic size nearly three times smaller than that allowed by the diffraction limit was obtained. Besides high-resolution imaging, the proposed near-field plate could be extended for other interesting applications, such as wireless power transfer or complex wavefront/beam shaper.

description: An analytic ground state is proposed for the unbiased spin-boson Hamiltonian, which is non-Gaussian and beyond the Silbey-Harris ground state with lower ground state energy. The infrared catastrophe in Ohmic and sub-Ohmic bosonic bath plays an important role in determining the degeneracy of the ground state. We show that the infrared divergence associated with the displacement of the nonadiabatic modes in bath may be removed from the proposed ground state for the coupling $α

description: In this paper we assess the impact of path reservation as an additional feature in our distributed real-time vehicle guidance protocol BeeJamA. Through our microscopic simulations we show that na\"ıve reservation of links without any further measurements is only an improvement in case of complete market penetration, otherwise it even reduces the performance of our approach based on real-time link loads. Moreover, we modified the reservation process to incorporate current travel times and show that this improves the results in our simulations when at least 40% market penetration is possible.

description: Accumulation of standardized data collections is opening up novel opportunities for holistic characterization of genome function. The limited scalability of current preprocessing techniques has, however, formed a bottleneck for full utilization of contemporary microarray collections. While short oligonucleotide arrays constitute a major source of genome-wide profiling data, scalable probe-level preprocessing algorithms have been available only for few measurement platforms based on pre-calculated model parameters from restricted reference training sets. To overcome these key limitations, we introduce a fully scalable online-learning algorithm that provides tools to process large microarray atlases including tens of thousands of arrays. Unlike the alternatives, the proposed algorithm scales up in linear time with respect to sample size and is readily applicable to all short oligonucleotide platforms. This is the only available preprocessing algorithm that can learn probe-level parameters based on sequential hyperparameter updates at small, consecutive batches of data, thus circumventing the extensive memory requirements of the standard approaches and opening up novel opportunities to take full advantage of contemporary microarray data collections. Moreover, using the most comprehensive data collections to estimate probe-level effects can assist in pinpointing individual probes affected by various biases and provide new tools to guide array design and quality control. The implementation is freely available in R/Bioconductor at http://www.bioconductor.org/packages/devel/bioc/html/RPA.html

description: In this paper we explore the maximum precision attainable in the location of a point source imaged by a pixel array detector in the presence of a background, as a function of the detector properties. For this we use a well-known result from parametric estimation theory, the so-called Cramer-Rao lower bound. We develop the expressions in the 1-dimensional case of a linear array detector in which the only unknown parameter is the source position. If the object is oversampled by the detector, analytical expressions can be obtained for the Cramer-Rao limit that can be readily used to estimate the limiting precision of an imaging system, and which are very useful for experimental (detector) design, observational planning, or performance estimation of data analysis software: In particular, we demonstrate that for background-dominated sources, the maximum astrometric precision goes as $B/F^2$, where $B$ is the background in one pixel, and $F$ is the total flux of the source, while when the background is negligible, this precision goes as $F^{-1}$. We also explore the dependency of the astrometric precision on: (1) the size of the source (as imaged by the detector), (2) the pixel detector size, and (3) the effect of source de-centering. Putting these results into context, the theoretical Cramer-Rao lower bound is compared to both ground- as well as spaced-based astrometric results, indicating that current techniques approach this limit very closely. Our results indicate that we have found in the Cramer-Rao lower variance bound a very powerful astrometric "benchmark" estimator concerning the maximum expected positional precision for a point source, given a prescription for the source, the background, the detector characteristics, and the detection process.

description: In the last half of the 20th century, academic excellence in engineering education was thought to be synonymous with learning skills associated with convergent thinking and production (Felder, 1988). Now, there has become a broader recognition that creativity and innovation abilities are essential to the success of engineers in the workplace. This recognition comes as today’s workplace is increasingly becoming an environment in which engineers tackle problems from broader perspectives with more interdisciplinary teams (Cropley, 2019; World Economic Forum, 2016; Rieken, 2017). In the present work, I aim to explore how higher education in mechanical engineering affects students’ creative approaches to solving an open-ended engineering design task. In doing so, I establish a framework to analyze different measures of creativity including fluency, novelty, elaboration, and completeness in a comparative study that evaluates 20 students majoring in mechanical engineering or psychology. Moreover, throughout this thesis, I uncover the underpinnings behind how mechanical engineering undergraduates explore decision-making pertaining to creativity and prototyping. The results of this study show a need to encourage mechanical engineering students to pursue additional ideas and to pursue these ideas to a greater extent. This work has implications for how future engineers integrate creativity into the workplace and how engineering is taught.

description: Within their lifetimes, 1 in 4 adults over the age of 25 worldwide can expect to suffer a stroke–a blood clot which blocks the flow of oxygen to regions of the brain, causing loss of motor function or death if left untreated. In this project, our team works with the biomedical firm Imperative Care to optimize an existing suite of equipment for a stroke treatment called ischemic thrombectomy, in which a series of nested catheters which are inserted into the patient’s arterial tract at the groin, maneuvered to the location of the blood clot, and placed under aspiration via attachment to an external vacuum pump. Ideally, this results in either the ingestion and removal of the blood clot or it being corked at the catheter’s tip. Our focus concerns the functionality of the external valves that interface with these catheters, called rotating hemostatic valves (RHVs). The RHV’s intended function is to seal off the vacuum pressure inside each catheter from the atmosphere, while also allowing the surgeon fine control of the position of the catheter. In the case that vacuum pressure is not maintained in the catheter, the blood clot can become irretrievable and/or the surgery can become prolonged, resulting in potential neurological damage to the patient. Mitigation or elimination of this scenario was the primary technical requirement of our redesign.
Testing determined that vacuum pressure is gradually lost due to a taper at the catheter’s tip, partially re-pressurizing the RHV as the catheter is pulled out, if the gasket seal is not tightened enough. Our team then designed a prototype which incorporates an integrated, one-way ball valve, an ACME threadform, a smaller length than most existing models, and a texturized user-interface for gasket adjustment. The main redesign is the placement of the one-way ball-valve, which functions like an airlock: the physician retracts a catheter into the RHV, seals off all catheters still in use from the environmental pressure by turning the valve, and then can fully remove the desired catheter without any possibility of impacting upstream pressure. The physician can then re-insert the catheter by opening the one-way ball valve at their discretion.
The final prototype was manufactured with SLA 3D-printing and then evaluated testing: most tests were successful, with the exceptions likely resulting from wear on the prototype over repeated trials. While the resultant product is not immediately ready for implementation, successful proof of concept testing has been thoroughly demonstrated. If implemented, our RHV design could well improve surgical outcomes of ischemic thrombectomy.
Transport in topologically disordered one-particle, tight-binding models

description: We aim at quantitatively determining transport parameters like conductivity, mean free path, etc., for simple models of spatially completely disordered quantum systems, comparable to the systems which are sometimes referred to as Lifshitz models. While some low-energy eigenstates in such models always show Anderson localization, we focus on models for which most states of the full spectrum are delocalized, i.e., on the metallic regime. For the latter we determine transport parameters in the limit of high temperatures and low fillings using linear response theory. The Einstein relation (proportionality of conductivity and diffusion coefficient) is addressed numerically and analytically and found to hold. Furthermore, we find the transport behavior for some models to be in accord with a Boltzmann equation, i.e., rather long mean free paths, exponentially decaying currents, while this does not apply to other models even though they are also almost completely delocalized.
The role of DNA endoreduplication in ABA's regulation of root growth in Arabidopsis thaliana

subject: Endoreduplication

description: Climate change is expected to bring shifts in global precipitation, and in areas where water availability is limiting, adaptations to water-deficit stress are essential. Roots play an essential role in acquiring nutrients and water necessary for plant plant growth, and recent research has shown that root growth patterns during periods of water stress can be highly variable within taxonomic groups. Abscisic acid (ABA) is a stress-response hormone that has been demonstrated to be an important regulator of root growth, and there is evidence that increasing ploidy in root cells, a process called endoreduplication, may increase root extension by enlarging root cell size.  However, the pathway through which ABA regulates root endoreduplication processes is still unclear. The purpose of this study is to investigate the divergence of the endoreduplication pathway in regulating root growth response to stress in the Brassicaceae family. For this project, DAPI staining and confocal fluorescence microscopy protocols were developed for quantification of nuclear area. Transgenic mutants were then used to identify the ABA-driven response of genes regulating endoreduplication in the model species Arabidopsis thaliana. Identifying the role of ABA in root developmental processes provides a better understanding of changes in root growth in response to environmental factors such as water stress. Furthermore, this research has the potential to inform new methods of plant genetic modification that support the goal of establishing new plant varieties better suited to the changing conditions of the anthropocene

description: 
The purpose of this study was to test the effect of donepezil (Aricept) on cognition in circadian arrhythmic Siberian hamsters, an animal model that mimics the breakdown of circadian rhythms in humans. This is because circadian dysfunction is known to accelerate cognitive impairment in not only Alzheimer’s disease, but adult- onset circadian dysfunction. Male Siberian hamsters were split into circadian-intact and circadian-arrhythmic groups and randomly assigned to either vehicle or donepezil treatment group. Animals in the donepezil treatment group received daily oral administration of 3.0mg/kg of donepezil dissolved in sugar water for 21 days. The vehicle group received the same amount of plain sugar water for the same amount of time. All animals were tested before and after treatment in a spontaneous alternation (SA) T-maze to measure cognition and spatial mapping. Surprisingly, the daily sugar water restored rhythms in all animals (vehicle and donepezil). Animals treated with donepezil performed significantly better in the alternation test than did the vehicle-treated group.
Event by event di-hadron correlations in Pb-Pb 2.76 TeV collisions from the ALICE experiment

Year: 2013

description: The large multiplicities at the LHC may permit flow harmonics to be determined on an event by event basis in Pb-Pb collisions. We extract these harmonics from event by event di-hadron correlations. Within a fine centrality bin, we find the correlation function varies substantially on an event by event basis, indicating large fluctuations in the initial conditions for a given impact parameter. Such large fluctuations lead to some events being highly triangular or highly elliptical, where the angular correlation function is completely dominated by the respective second and third Fourier harmonics. We will show unfolded $v_{2}$ distributions for various centralities, and implications for our understanding of the initial conditions.

description: In the present work the case of a chromium Bose-Einstein condensate is considered. The model includes not only the presence of the so-called contact interaction but also a long range and anisotropic dipole-dipole interaction has been included. Some thermodynamical properties are analyzed. For instance, the size of the condensate, chemical potential, speed of sound, number of particles, etc., are deduced. It will be shown that this dipole-dipole interaction implies the emergence of anisotropy, for example, in the speed of sound. The possible use of this anisotropy as a tool for the analyze of dissipative mechanisms, for instance, Landau's criterion for superfluidity, will be also discussed.
Chronic Smoke Exposure Burden: Impact on the Immune System of Firefighters

description: Firefighters are exposed to significant levels of smoke during their careers. Long-term smoke exposure has been associated with chronic diseases and cancers in firefighters. Furthermore, smoke exposure has been associated with the long-term accumulation of heavy metals (e.g., lead, arsenic), which have toxic effects. Despite these known risk factors, the impact of this pollutant burden on the immune system of firefighters remains largely unknown. The goal of this study was to characterize the immune dysfunction caused by chronic smoke exposure and identify possible associations with heavy metals in firefighters versus controls. 
We profiled peripheral blood mononuclear cells (PBMCs) utilizing cytometry time of flight (CyTOF) and measured heavy metal levels in the cells during CyTOF by utilizing available heavy metal channels in a cohort of San Francisco firefighters (n=9; 21-52 years;) and healthy controls (n=9; 26-58 years) with a similar level of baseline pollution exposure. FlowJo was used to identify cell populations.
The firefighter group had a lower frequency of CD45- CCR7+CD27- NK cells in the live cell population (p<0.02) and in the NK cell population (p=0.016).  Lower cell counts (p<0.05) were found in the firefighter group compared to control in B cells that were positive for Cd 106, Pb 204, and W 182 and CD4+ cells that were positive for Pb 204 and Pb 208. These results suggest chronic smoke exposure may alter the frequency of CD45- CCR7+CD27- NK cells and accumulation of certain heavy metals compared to healthy controls. 
This study expands our current knowledge of potential mechanisms of immune dysfunction associated with smoke exposure and heavy metals in firefighters.

While at first glance the behaviour seems to be in accordance with Hückel's rule, a theoretical analysis reveals no significant charge transfer. The driving mechanism for the conformational change is hybridisation at the organic-metal interface and does not necessitate any charge transfer.

description: Incomputability as a mathematical notion arose from work of Alan Turing and Alonzo Church in the 1930s. Like Turing himself, it attracted less attention than it deserved beyond the confines of mathematics. Today our experiences in computer science, physics, biology, artificial intelligence, economics and the humanities point to the importance of the notion for understanding the world around us. This article takes a Turing centenary look at how the interface between the computable world and the incomputable formed a central theme in Turing's work - from the early establishment of the standard model of the stored program computer, to the late work on emergence of form in nature, and the first approaches to understanding and simulating human intelligence. Turing's thinking was remarkably prescient, and his legacy still impacts on much of our work. The incomputable may turn out to be a specially important part of the legacy, with consequences that Alan Turing himself could not have envisaged.
Supersymmetric SO(10) GUTs with sliding scales

description: We construct lists of supersymmetric models with extended gauge groups at intermediate steps, all of which are based on SO(10) unification. We consider three different kinds of setups: (i) The model has exactly one additional intermediate scale with a left-right (LR) symmetric group; (ii) SO(10) is broken to the LR group via an intermediate Pati-Salam (PS) scale; and (iii) the LR group is broken into $SU(3)_{c} \times SU(2)_{L} \times U(1)_{R} \times U(1)_{B-L}$, before breaking to the SM group. We use sets of conditions, which we call the "sliding mechanism", which yield unification with the extended gauge group(s) allowed at arbitrary intermediate energy scales. All models thus can have new gauge bosons within the reach of the LHC, in principle. We apply additional conditions, such as perturbative unification, renormalizability and anomaly cancellation and find that, despite these requirements, for the ansatz (i) with only one additional scale still around 50 different variants exist that can have an LR symmetry below 10 TeV. For the more complicated schemes (ii) and (iii) literally thousands of possible variants exist, and for scheme (ii) we have also found variants with very low PS scales. We also discuss possible experimental tests of the models from measurements of SUSY masses. Assuming mSugra boundary conditions we calculate certain combinations of soft terms, called "invariants", for the different classes of models. Values for all the invariants can be classified into a small number of sets, which contain information about the class of models and, in principle, the scale of beyond-MSSM physics, even in case the extended gauge group is broken at an energy beyond the reach of the LHC.

description: A large solar pore with a granular light bridge was observed on October 15, 2008 with the IBIS spectrometer at the Dunn Solar Telescope and a 69-min long time series of spectral scans in the lines Ca II 854.2 nm and Fe I 617.3 nm was obtained. The intensity and Doppler signals in the Ca II line were separated. This line samples the middle chromosphere in the core and the middle photosphere in the wings. Although no indication of a penumbra is seen in the photosphere, an extended filamentary structure, both in intensity and Doppler signals, is observed in the Ca II line core. An analysis of morphological and dynamical properties of the structure shows a close similarity to a superpenumbra of a sunspot with developed penumbra. A special attention is paid to the light bridge, which is the brightest feature in the pore seen in the Ca II line centre and shows an enhanced power of chromospheric oscillations at 3-5 mHz. Although the acoustic power flux in the light bridge is five times higher than in the "quiet" chromosphere, it cannot explain the observed brightness.

description: Today, museum owners, curators, and donors continue to recreate history through a Western lens by showcasing Indigenous art as artifact and by not including modern and contemporary pieces by Native artists. Contemporary Native art is particularly important to showcase in learning institutions such as museums because they underscore that Native individuals continue to exist, are important, and are multifaceted. This is beneficial for both Native and non-Native individuals, for the inclusion of modern art challenges dated ideas of Indigenous identity, expanding Native possibility and confronting non-Natives understanding of Indigeneity.

These objects were selected based on bright optical counterparts which were quickly found to have emission lines in their optical spectra. This paper presents an illustration of GBS optical follow-up, targeting emission line objects. Of these five objects, four exhibit photometric variability in the Sloan r' band. CX5 shows a tentative period of 2.1 hours and is clearly an Intermediate Polar (IP). CX28 and CX37 both exhibit flickering with no clear period. Both are suggested to also be IPs. CX18 was observed to undergo 2 dwarf nova outbursts. Finally, CX561 shows no detectable variability, although its characteristics would be consistent with either a quiescent Low Mass X-ray Binary or Cataclysmic Variable.

description: Although the magnetoelectric effects - the mutual control of electric polarization by magnetic fields and magnetism by electric fields, have been intensively studied in a large number of inorganic compounds and heterostructures, they have been rarely observed in organic materials. Here we demonstrate magnetoelectric coupling in a metal-organic framework [(CH3)2NH2]Mn(HCOO)3 which exhibits an order-disorder type of ferroelectricity below 185 K. The magnetic susceptibility starts to deviate from the Curie-Weiss law at the paraelectric-ferroelectric transition temperature, suggesting an enhancement of short-range magnetic correlation in the ferroelectric state. Electron spin resonance study further confirms that the magnetic state indeed changes following the ferroelectric phase transition. Inversely, the ferroelectric polarization can be improved by applying high magnetic fields. We interpret the magnetoelectric coupling in the paramagnetic state in the metal-organic framework as a consequence of the magnetoelastic effect that modifies both the superexchange interaction and the hydrogen bonding.

description: Lie and Q-conditional symmetries of the classical three-component diffusive Lotka - Volterra system in the case of one space variable are studied. The group-classification problems for finding Lie symmetries and Q-conditional symmetries of the first type are completely solved. Notably, non-Lie symmetries (Q-conditional symmetry operators) for a multi-component non-linear reaction-diffusion system are constructed for the first time. An example of non-Lie symmetry reduction for solving a biologically motivated problem is presented.

description: Using Herschel data from the deepest SPIRE and PACS surveys (HerMES and PEP) in COSMOS and GOODS (N+S), we examine the dust properties of IR-luminous (L_IR>10^10 L_sun) galaxies at 0.145K) SEDs and cold (T<25K), cirrus-dominated SEDs are rare, with most sources being within the range occupied by warm starbursts such as M82 and cool spirals such as M51. We observe a luminosity-temperature (L-T) relation, where the average dust temperature of log[L_IR/L_sun]=12.5 galaxies is about 10K higher than that of their log[L_IR/L_sun]=10.5 counterparts. However, although the increased dust heating in more luminous systems is the driving factor behind the L-T relation, the increase in dust mass and/or starburst size with luminosity plays a dominant role in shaping it. Our results show that the dust conditions in IR-luminous sources evolve with cosmic time: at high redshift, dust temperatures are on average up to 10K lower than what is measured locally. This is manifested as a flattening of the L-T relation, suggesting that (U)LIRGs in the early Universe are typically characterised by a more extended dust distribution and/or higher dust masses than local equivalent sources. Interestingly, the evolution in dust temperature is luminosity dependent, with the fraction of LIRGs with T<35K showing a 2-fold increase from z~0 to z~2, whereas that of ULIRGs with T<35K shows a 6-fold increase.

An Urban Earthquake Disaster Risk Index

description: The Earthquake Disaster Risk Index (EDRI) is a composite index that allows direct comparison of the relative overall earthquake disaster risk of cities worldwide, and describes the relative contributions of various factors to that overall risk. The development of the EDRI brings together a body of knowledge about earthquake disasters from a wide range of disciplines to provide three principal benefits.

First, the direct comparison of overall earthquake disaster risk provides a useful tool for inter-city allocation of mitigation resources and effort. Most previous work in earthquake risk assessment has focused on a single component of the risk, and/or on a single region. The EDRI provides a systematic way to directly compare the overall earthquake disaster risk across a large number of cities or regions. Second, the disaggregated EDRI will increase awareness of the wide range of factors on which a city's earthquake disaster risk depends, from the expected magnitude of ground shaking, to the number of structures, to a city’s current economic situation. A comprehensive EDRI will highlight the fact that even in urban regions with low seismicity, an earthquake may occur, and if it does, the other characteristics of the city could turn that single event into a major disaster. Third, by reevaluating the index periodically, the EDRI may be used to monitor trends in earthquake disaster risk over time.

The EDRI has been developed using the following six-step procedure: (1) create a conceptual framework of all the factors that contribute to earthquake disaster risk—geological, engineering, economic, social, political, and cultural factors; (2) identify simple, measurable indicators to represent each of the factors in the framework (e.g., population, per capita Gross Domestic Product, percentage of the urbanized area that is soft soil); (3) combine the indicators mathematically into the composite EDRI; (4) gather data and evaluate the EDRI for each of the world’s major cities, (5) perform a sensitivity analysis to determine the robustness of the results, (6) interpret the numerical findings to assess their reasonableness and implications, and present the results in a variety of easily understandable graphical forms. A ten-city sample analysis was conducted to explore the challenges associated with this process, and to illustrate its feasibility and the usefulness of the results.

description: If an ultrarelativistic charged particle channels inside a single crystal with periodically bent crystallographic planes, it emits hard electromagnetic radiation of the undulator type. Due to similarity of its physical principles to the ordinary (magnetic) undulator, such a device is termed as the crystalline undulator. Recent development of a new Monte Carlo code ChaS made possible a detailed simulation of particle channeling and radiation emission in periodically bent crystals. According to recent findings, energy of the electron beam below 1 GeV is sufficient to observe the undulator effect in a periodically bent crystal. Even more exciting results were obtained for a crystalline undulator whose bending period is shorter than the period of the channeling oscillations and the bending amplitude is smaller than the width of the planar channel. Such a crystalline undulator is far superior to what was proposed previously. It allows for a large effective number of undulator periods. Therefore, it is predicted to emit intense undulator radiation in the forward direction. A narrow undulator peak is seen for both positron and electron beams. Using positrons is, however, more desirable because in this case the intensity of the undulator radiation is higher while the background is lower.

description: Although Brazil has increased school enrollment in the past decades, inequalities in learning outcomes persist across regions, states, and municipalities. In this context, state-level education management, specifically middle-tier management (i.e., regional education offices), plays a central role in supporting the educational achievement of students from different regions. This mixed-methods study examines the association between middle-tier management practices and school performance in the state of Minas Gerais. Using a fixed effects regression model, I analyze student test scores from 2009 to 2018 to identify differences in regional education offices’ value-added to school achievement. Based on quantitative results, I select consistently top- and bottom-performing offices for in-depth interviews. Quantitative results demonstrate significant variation in regional education offices’ value-added to school achievement statewide, and qualitative analyses further reveal variation in management practices between top and bottom performers. Whereas top-performing  offices emphasize targeting, monitoring, and recruitment among their management practices, bottom performers emphasize incentives.

description: Carbon nanomaterials continue to amaze scientists due to their exceptional physical properties. Recently there have been theoretical predictions and first reports on graphene multilayers, where, due to the rotation of the stacked layers, outstanding electronic properties are retained while the susceptibility to degradation and mechanical stress is strongly reduced due to the multilayer nature. Here we show that fully turbostratic multilayer graphitic microstructures combine the high charge carrier mobilities necessary for advanced electronic and spintronic devices with the robustness of graphitic structures. Structural characterization of disk-shaped graphitic microstructures using Raman spectroscopy and Transmission Electron Microscopy (TEM) reveals Moiré and diffraction patterns corroborating their turbostratic nature. Electronic transport characterization yields reproducible high mobilities > 105 cm^2(Vs)^(-1) independent of the disks thickness, which is a direct consequence of the electronic decoupling induced by the turbostratic stacking.
