title: DEPRECATED: Evolutionary Decomposition of Complex Design Spaces
Creators: name: BONHAM, CHRISTOPHER RICHARD
Publisher: name: University of Plymouth
Year: 2000

description: This dissertation investigates the support of conceptual engineering design through the decomposition of multi-dimensional search spaces into regions of high performance. Such decomposition helps the designer identify optimal design directions by the elimination of infeasible or undesirable regions within the search space. Moreover, high levels of interaction between the designer and the model increases overall domain knowledge and significantly reduces uncertainty relating to the design task at hand. The aim of the research is to develop the archetypal Cluster Oriented Genetic Algorithm (COGA) which achieves search space decomposition by using variable mutation (vmCOGA) to promote diverse search and an Adaptive Filter (AF) to extract solutions of high performance [Parmee 1996a, 1996b]. Since COGAs are primarily used to decompose design domains of unknown nature within a real-time environment, the elimination of apriori knowledge, speed and robustness are paramount. Furthermore COGA should promote the in-depth exploration of the entire search space, sampling all optima and the surrounding areas. Finally any proposed system should allow for trouble free integration within a Graphical User Interface environment. The replacement of the variable mutation strategy with a number of algorithms which increase search space sampling are investigated. Utility is then increased by incorporating a control mechanism that maintains optimal performance by adapting each algorithm throughout search by means of a feedback measure based upon population convergence. Robustness is greatly improved by modifying the Adaptive Filter through the introduction of a process that ensures more accurate modelling of the evolving population. The performance of each prospective algorithm is assessed upon a suite of two-dimensional test functions using a set of novel performance metrics. A six dimensional test function is also developed where the areas of high performance are explicitly known, thus allowing for evaluation under conditions of increased dimensionality. Further complexity is introduced by two real world models described by both continuous and discrete parameters. These relate to the design of conceptual airframes and cooling hole geometries within a gas turbine. Results are promising and indicate significant improvement over the vmCOGA in terms of all desired criteria. This further supports the utilisation of COGA as a decision support tool during the conceptual phase of design.
Magnetic aspects of QCD at finite density and temperature

description: Some magnetic aspects of QCD are discussed at finite density and temperature. Possibility of spontaneous magnetization is studied within Landau Fermi-liquid theory, and the important roles of the screening effects for gluon propagation are elucidated. Static screening for the longitudinal gluons improves the infrared singularities, while the transverse gluons receive only dynamic screening. The latter property gives rise to a novel non-Fermi-liquid behaviour for the magnetic susceptibility. Appearance of a density-wave state is also discussed in relation to chiral transition, where pseudoscalar condensate as well as scalar one takes a spatially non-uniform form in a chirally invariant way. Accordingly magnetization of quark matter oscillates like spin density wave. A hadron-quark continuity is suggested in this aspect, remembering pion condensation in hadronic phase.

Family medicine residents’ oral health-related training, attitudes, and practices towards infant oral health
Creators: name: Abushanan, AlWaleed

Year: 2018

description: Objectives: To evaluate family medicine residency curricula content pertaining to, and residents’ training in, infants’ oral health in Canada. Methods: Two brief self-administered online surveys were developed using Research Electronic Data Capture (REDCap). One survey targeted all the 17 Canadian family medicine training program directors, and another target the currently enrolled residents within these programs. Questions focused on training, attitudes and practices towards infant oral health. Statistical tests were performed using SPSS version 22 with a confidence interval of 95% and a significance level of 0.05. Results: A total of 11 family medicine directors and 155 family medicine residents responded to the survey. The vast majority 90% (N=10) of the directors indicated that clinical oral health screening was not incorporated into the curriculum, particularly around early childhood caries. Over half the residents (53%, n=82) reported that they did not feel their training was adequate to identify dental caries in children. As 41% (n=63) of the residents described the quality of their training in oral health-related topics during their residency to be poor, more than two thirds (62%, n=96) of them seldom performed a visual examination of the children’s teeth. Although family medicine residents felt that physicians have an important role in promoting oral health among infants and toddlers, the majority (72%, n=112) of them reported lack of knowledge and training as the main barriers to performing oral health-related practices. Conclusion: Most of the Family Physicians training programs in Canada do not include infant oral health screening in their curriculum. While the majority of family medicine residents felt that physicians have an important role in promoting oral health amongst children, the reported lack of knowledge and training were hindering them from performing various oral health-related practices.

description: The bright, nearby, recently discovered supernova SN2010jl is a member of the rare class of relatively luminous Type~IIn events. Here we report archival HST observations of its host galaxy UGC5189A taken roughly 10yr prior to explosion, as well as early-time optical spectra of the SN. The HST images reveal a bright, blue point source at the position of the SN, with an absolute magnitude of -12.0 in the F300W filter. If it is not just a chance alignment, the source at the SN position could be (1) a massive young (less than 6 Myr) star cluster in which the SN resided, (2) a quiescent, luminous blue star with an apparent temperature around 14,000K, (3) a star caught during a bright outburst akin to those of LBVs, or (4) a combination of option 1 and options 2 or 3. Although we cannot confidently choose between these possibilities with the present data, any of them imply that the progenitor of SN2010jl had an initial mass above 30Msun. This reinforces mounting evidence that many SNe IIn result from very massive stars, that massive stars can produce visible SNe without collapsing quietly to black holes, and that massive stars can retain their H envelopes until shortly before explosion. Standard stellar evolution models fail to account for these observed properties.

Why am I so tired after my stroke?

Publisher: name: Zenodo

description: Background
Fatigue is a common complaint after a stroke, and contributes to the large national burden of caring for stroke victims. Nevertheless, causes and cures for post-stroke fatigue are generally under-appreciated.
Discussion:
Post-stroke fatigue can be organic, psychological, emotional, or a combination of these. A precise diagnosis will aid in treatment planning for effective return to normal levels of activity. Depending on the cause of fatigue, a post-stroke patient may benefit from physical therapy, occupational therapy, anti-depressants, counseling, and careful attention to basic needs. However, patients and care-givers should be patient and recognize that a stroke victims may never fully recover their abilities and dealing with fatigue may be a long-term issue.
Conclusion:
Post-stroke fatigue can be vexing but multi-modal rehabilitation often allows at least some improvement. Additional research on effective therapy for different sources of fatigue will benefit our stroke patients in the future.

description: Fourier-Legendre decomposition (FLD) of solar Doppler imaging data is a promising method to estimate the sub-surface solar meridional flow. FLD is sensible to low-degree oscillation modes and thus has the potential to probe the deep meridional flow. We present a newly developed code to be used for large scale FLD analysis of helioseismic data as provided by the Global Oscillation Network Group (GONG), the Michelson Doppler Imager (MDI) instrument, and the upcoming Helioseismic and Magnetic Imager (HMI) instrument. First results obtained with the new code are qualitatively comparable to those obtained from ring-diagram analyis of the same time series.

The rising cost of falling
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background
As a person ages, falls and strokes each become more likely, and because stroke patients are independently at increased risk for falling, the risk of falls is compounded in this population.
Discussion:
There are a number of preventive measures that can be easily implemented to decrease the risk of falling. These are well known to physical and occupational therapists, so a consultation is well-advised. Four areas of focus are: (1) Exercise, to increase strength, balance, and coordination. (2) Vision, to assure that the subject sees as well as possible. (3) Medication, to minimize side effects that could influence falling. (4) Environment, to remove obstacles, add assists, and provide optimal lighting.
Conclusion:
Falls among stroke patients are costly in terms of risk to the individual and treatment demands on the healthcare system. However, simple attention to details can reduce the risk of falling.

description: A method for approximating dark soliton solutions of the nonlinear Schrodinger equation under the influence of perturbations is presented. The problem is broken into an inner region, where core of the soliton resides, and an outer region, which evolves independently of the soliton. It is shown that a shelf develops around the soliton which propagates with speed determined by the background intensity. Integral relations obtained from the conservation laws of the nonlinear Schrodinger equation are used to approximate the shape of the shelf. The analysis is developed for both constant and slowly evolving backgrounds. A number of problems are investigated including linear and nonlinear damping type perturbations.

description: We study the spin diffusion in a two-dimensional electron gas at the interface of oxide heterostructure LaAlO$_3$/SrTiO$_3$ grown on multiferroic TbMnO$_3$ at 15 K by means of the kinetic spin Bloch equation approach. The spiral magnetic moments of Mn$^{3+}$ in TbMnO$_3$ interact with the diffusing spins at the LaAlO$_3$/SrTiO$_3$ interface via the Heisenberg exchange interaction. It is demonstrated that the spin diffusion length is always finite, despite the polarization direction of the injected spins. Our study also reveals the important role played by the Coulomb scattering, which can effectively suppress the spin diffusion.

description: Magnetic reversal processes of a FePt/α-Fe/FePt trilayer system with in-plane easy axes have been investigated within a micromagnetic approach. It is found that the magnetic reversal process consists of three steps: nucleation of a prototype of domain wall in the soft phase, the evolution as well as the motion of the domain wall from the soft to the hard phase and finally, the magnetic reversal of the hard phase. For small soft layer thickness Ls, the three steps are reduced to one single step, where the magnetizations in the two phases reverse simultaneously and the hysteresis loops are square with nucleation as the coercivity mechanism. As Ls increases, both nucleation and pinning fields decrease. In the meantime, the single-step reversal expands to a standard three-step one and the coercivity mechanism changes from nucleation to pinning. The critical thickness where the coercivity mechanism alters, could be derived analytically, which is found to be inversely proportional to the square root of the crystalline anisotropy of the hard phase. Further increase of Ls leads to the change of the coercivity mechanism from pinning to nucleation.

Dynamical properties of a nonequilibrium quantum dot close to localized-delocalized quantum phase transitions

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We calculate the dynamical decoherence rate and susceptibility of a nonequilibrium quantum dot close to the delocalized-to-localized quantum phase transitions. The setup concerns a resonance-level coupled to two spinless fermionic baths with a finite bias voltage and an Ohmic bosonic bath representing the dissipative environment. The system is equivalent to an anisotropic Kondo model. As the dissipation strength increases, the system at zero temperature and zero bias show quantum phase transition between a conducting delocalized phase to an insulating localized phase. Within the nonequilibrium functional Renormalization Group (FRG) approach, we address the finite bias crossover in dynamical decoherence rate and charge susceptibility close to the phase transition. We find the dynamical decoherence rate increases with increasing frequency. In the delocalized phase, it shows a singularity at frequencies equal to positive or negative bias voltage. As the system crossovers to the localized phase, the decoherence rate at low frequencies get progressively smaller and this sharp feature is gradually smeared out, leading to a single linear frequency dependence. The dynamical charge susceptibility shows a dip-to-peak crossover across the delocalized-to-localized transition. Relevance of our results to the experiments is discussed.

The effects of charter school proliferation and locational decisions on the finances of public district schools
Creators: name: Weber, Mark
Publisher: name: No Publisher Supplied
Year: 2019

description: Charter schools have become a substantial part of the U.S. school system; however, relatively little is known about how charter proliferation affects the finances of the public school districts within whose boundaries charters reside. This three-paper dissertation leverages unique datasets to ascertain the effects of charter growth on school spending and other resource measures. In paper one, I employ fixed-effects models on national data to estimate the effects of charter proliferation on a variety of school resource measures. In many states, charter growth correlates with increased spending; however, inconsistencies in federal data suggest that in some states this increase may be mechanical. Further analysis of state-level data from Minnesota and New Jersey finds evidence, however, that the increased spending is due to fixed costs in public school districts that are inelastic to enrollment decreases due to charter proliferation. The second paper further examines New Jersey data. I find that school district spending increases in the early stages of charter growth, then falls after a “turnaround” point. Analysis of both fiscal and staffing measures suggests resources vary in their elasticity to charter proliferation. Paper three analyzes correlations between demographic characteristics of census tracts and the probability a charter school is inside the tract. I find that poverty significantly increases the chance a charter is present within a neighborhood, while an increase in the percentage of white residents decreases that same probability. This suggests the growth in spending found in papers one and two, which appears to induce inefficiencies, is not evenly spread among tracts of differing socio-economic and racial characteristics. This dissertation makes contributions to the literature on charter schools by presenting empirical evidence that charter proliferation is not a fiscally neutral policy and that the consequences of charter growth are not evenly distributed across socioeconomic status or race.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Let $C^*(E)$ be the graph $C^*$-algebra associated to a graph E and let J be a gauge invariant ideal in $C^*(E)$. We compute the cyclic six-term exact sequence in $K$-theory of the associated extension in terms of the adjacency matrix associated to $E$. The ordered six-term exact sequence is a complete stable isomorphism invariant for several classes of graph $C^*$-algebras, for instance those containing a unique proper nontrivial ideal. Further, in many other cases, infinite collections of such sequences comprise complete invariants. Our results allow for explicit computation of the invariant, giving an exact sequence in terms of kernels and cokernels of matrices determined by the vertex matrix of $E$.

description: Background and Purpose
For unclear reasons the blood pressure in acute stroke patients is elevated and falls over next few days. Stress in emergency department has been suggested as an etiology. To study this, we compared the prevalence of elevated blood pressure in adult patients presenting to the emergency department (ED) with hypertension related diseases.
Methods:
We used data from the 2003 National Hospital Ambulatory Medical Care Survey (NHAMCS). Patients with clinical conditions requiring specific management of elevated blood pressure, namely, stroke, acute coronary syndrome, heart failure and traumatic brain injury were selected using ICD-9CM primary codes. Prevalence of acute systolic blood pressure (BP) ≥140 mmHg and ≥180 mmHg, and, systolic and diastolic BP≥140/90 mmHg and ≥180/110 mmHg were compared across the clinical conditions listed above.
Results:
The prevalence of BP≥140/90 mmHg on presentation to ED was significantly higher for stroke patients (78%) compared to patients with heart failure (55%, p<0.05) and traumatic brain injury (42%, p<0.05). The difference was not significant compared to acute coronary syndrome (63%).

description: Models with an extended Higgs sector, as the NMSSM, allow for scenarios where the Standard Model-like CP-even Higgs boson H decays dominantly as H -> AA -> 4 tau where A is a light CP-odd Higgs boson. Tight constraints on this scenario in the form of lower bounds on M_H have recently been published by the ALEPH group. We show that, due to A - eta_b mixing, the branching ratio H -> AA -> 4 tau is strongly reduced for M_A in the range 9 - 10.5 GeV. This is the range of M_A in which the tension between the observed eta_b(1S) mass and its prediction based on QCD can be resolved due to mixing, and which is thus still consistent with a light CP-even Higgs boson H satisfying LEP constraints with a mass well below 114 GeV. This result is practically independent from the coupling of A to b quarks.

description: We present the microscopic treatment of edge magnetoplasmons (EMPs) for the regime of not-too-low temperatures defined by the condition $\hbar ω_{c}\gg k_{B}T\gg \hbar v_{g}/2\ell_{0}$, where $v_{g}$ is the group velocity of the edge states, $\ell_{0}=\sqrt{\hbar /m^{\ast}ω_{c}}$ is the magnetic length and $ω_{c}$ is the cyclotron frequency. We find a weakly damped symmetric mode, named helical edge magnetoplasmon, which is localized at the edge states region for filling factors $ν=1, 2$ and \textit{very strong dissipation} $η_{T}=ξ/k_{x}\ell_{T}\agt\ln (1/k_{x}\ell_{T})\gg 1$, where the characteristic length $\ell_{T}=k_{B}T\ell_{0}^{2}/\hbar v_{g}\gg \ell_{0}/2$ with $ξ$ being the ratio of the local transverse conductivity to the local Hall conductivity at the edge states and $k_{x}$ is the wave vector along the edge; here other EMP modes are strongly damped. The spatial structure of the helical edge magnetoplasmon, transverse to the edge, is strongly modified as the wave propagates along the edge. In the regime of \textit{weak dissipation}, $η_{T}\ll 1$, we obtain exactly the damping of the fundamental mode as a function of $k_{x}$. For $ν=4$ and weak dissipation we find that the fundamental modes of $n=0$ and $n=1$ Landau levels (LLs) are strongly renormalized due to the Coulomb coupling. Renormalization of all these EMPs coming from a metal gate and air half-space is studied.

description: Informed consent for pharmacogenomic testing in people with a learning disability Background Advances in genomic healthcare will enable medication to be tailored to each individual’s needs, based on subtle genetic variations. This will result in individuals being asked to consent to genetic testing for this purpose. The recent political agenda for social change has emphasised the right of people with learning disabilities to have more autonomy and make their own decisions. There have also been significant changes in the way healthcare practitioners relate to their patients, with a shift away from paternalism towards shared decision-making. Research Aim The aims of the study were (1) to explore the information needs of people with mild to moderate learning disabilities with respect to pharmacogenomic tests and (2) to identify ways of facilitating informed consent. Methods An integrative literature review was conducted to identify research on informed consent to healthcare interventions in people with learning disabilities (Phase 1). Subsequent phases (Phases 2-4) of the study were conducted using an ethnographic approach. Phase 2 involved observation of six participants with learning disabilities undergoing a routine blood test consultation in general practice. This was followed by Phase 3, in which semi-structured interviews with 14 participants with learning disabilities were conducted. In Phase 4, three different methods were used: focus groups with carers (four paid carers, five family carers), an on-line bulletin board for healthcare professionals (five participants) and interviews with six key informants from the field of learning disability. Findings The data showed consent procedures were often inadequate and there was inconsistent knowledge of mental capacity law amongst health professionals. Provision of information to patients prior to a blood test was variable, but interviews with people with learning disabilities revealed the fact that this information may not be wanted by them. People with learning disabilities viewed pharmacogenomic tests as similar to other blood tests and would want access to them. The attitudes of paid carers and family carers differed in terms of decision-making opportunities for people with learning disabilities. Conclusions Healthcare practitioners, carers and people with learning disability need to be familiar with the principles of the Mental Capacity Act to facilitate valid consent in the healthcare context. Healthcare practitioners also need to be made aware of developments in pharmacogenomics if it is to become part of routine health care. Finally, this study demonstrated the value of qualitative research in exploring the knowledge and attitudes of people with learning disability.

description: This article describes a method to build syntactical dependencies starting from the phrase structure parsing process. The goal is to obtain all the information needed for a detailled semantical analysis. Interaction Grammars are used for parsing; the saturation of polarities which is the core of this formalism can be mapped to dependency relation. Formally, graph patterns are used to express the set of constraints which control dependency creations.
Multidimensional hybrid nanomaterial approaches for therapeutic and diagnostic applications

description: Nanomaterials are highly versatile and allow us to effectively and dynamically control a myriad of biomedical application from stem cell differentiation to diagnostics and translational therapeutics. While the scientific community has made tremendous strides in understanding disease and treatments, the complexities of disease and injuries still undermine the full realization of therapies. To this end, this dissertation will focus on the approaches within the novel nanotechnology toolbox for addressing multiple challenges in the field of regenerative medicine with the ultimate goal to regrow and reform damaged tissues and organs. Specifically, this dissertation addresses the regeneration of neural tissues within the central nervous system as the regeneration of such tissue is extremely challenging in the first two decades of the 21$^{st}$ century.The first part of the dissertation will focus on the innovative insoluble extracellular approaches for controlling the differentiation of neural stem cells (NSCs) into neurons and supporting cells such as oligodendrocytes. Traditionally, biologists have focused on introducing exogenous materials such as proteins and chemical factors to induce specific stem cell differentiation. The goal of our novel insoluble nanomaterial approaches is to uncover the interaction between cells and their surrounding environments for differentiation. The second part of the thesis will focus on the clinical translational approaches of nanomaterials. Through a novel, non-viral transient gene manipulation method developed by Prof. Lee research laboratory, NanoScript, a nanoparticle-based synthetic transcription factor was tasked to regenerate axon in spinal cord injury. This demonstration is tremendous progress in regenerative medicine as it holds a promise for the regulation of every gene expression in a living biological system. Finally, this dissertation will focus on the development of highly sensitive, selective, real-time, and non-invasive characterizations of stem cell differentiation. The development of such an approach will have a significant impact on cell-based therapy. By overcoming the destructive nature of traditional cellular characterization methods, the clinicians can confirm the mature differentiation of stem cells before transplantation to completely avoid potential tumor formation. As such, more cell-based therapies will find their ways into clinical applications. Altogether, this dissertation covers the widely collaborative nanomaterial-based approaches from guiding the differentiation of stem cell, biosensing, and non-viral nanoparticle for gene expression regulation, to the transplantable nanofiber-nanomaterial hybrid scaffold with the foundation of nanochemistry with well-defined biochemical, chemical, and physical compositions, shapes, and properties.

description: We report on extensive photometry of DK Lac obtained during the interval 1990-2009, which includes a 2 mag low state during 2001-2003. Much of the photometry consists of exposures obtained with a typical spacing of several days, but also includes 26 sequences of continuous photometry each lasting 2 to 7 hours. We find no evidence for periodicities in our data. We do find that the random variations in the low state are ~2x those in the high state, when expressed in magnitudes. The lack of orbital-time-scale variations is attributed to the nearly face-on presentation of the disk. There is a 0.2 mag decline in the high state brightness of the system over 19 years, which is consistent with the behavior of other old novae in the decades following outburst. High-state spectra are also presented and discussed. We find that the equivalent width of H$α$ falls by ~2x from 1991 to 2008. The photometric properties are discussed in the context of the hibernation scenario for the behavior of novae between outbursts, in which we conclude that low states in old novae are probably unrelated to their possible entrance into hibernation.

description: We present transport measurements of electrons on the surface of liquid helium in a microchannel device in which a constriction may be formed by a split-gate electrode. The surface electron current passing through the microchannel first decreases and is then completely suppressed as the split-gate voltage is swept negative. The current decreases in a steplike manner, due to changes in the number of electrons able to pass simultaneously through the constriction. We investigate the dependence of the electron transport on the AC driving voltage and the DC potentials applied to the sample electrodes, in order to understand the electrostatic potential profile of the constriction region. Our results are in good agreement with a finite element modeling analysis of the device. We demonstrate that the threshold of current flow depends not only on the applied potentials but also on the surface electron density. The detailed understanding of the characteristics of such a device is an important step in the development of mesoscopic experiments with surface electrons on liquid helium.

description: Scoping reviews have a broad approach to topics, allowing for the gathering of various study designs with the purpose of recognizing the evidence produced. In the literature, information regarding the extraction and analysis of results is still incipient, which led JBI collaborators to develop new recommendations in 2023 for conducting a scoping review, specifically regarding extraction, analysis, and presentation of results. Objective: To map existing literature regarding the extraction, analysis, and presentation of results in scoping reviews in the context of Brazilian nursing. Method: Considering the research question "How have scoping reviews been conducted regarding the extraction, analysis, and presentation of results in the context of Brazilian nursing?" a scoping review is proposed, according to the Joanna Briggs Institute methodology, which will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews (PRISMA-ScR). For the search of studies, the following sources of information will be consulted: LILACS, PubMed, CINAHL, Embase, Scopus, JBI EBP Database, Cochrane, Web of Science, Google Scholar, and the Catalog of Theses and Dissertations of the Coordination of Improvement of Higher Education Personnel. The reference manager Endnote and the web application Rayyan will be used for removal of duplicates and for individual study selection. Selection will be performed by two reviewers, with the participation of a third for conflict resolution. A data collection script will be proposed for data extraction. Results will be presented in tables, both descriptively and graphically, according to the obtained data. It is expected that this study will bring subsidies for the extraction, analysis, and presentation of results in scoping reviews in the context of Brazilian nursing, contributing to the quality of productions in the national scenario.

description: Recently, we presented the detection of carbon monoxide in the transmission spectrum of extrasolar planet HD209458b, using CRIRES, the Cryogenic high-resolution Infrared Echelle Spectrograph at ESO's Very Large Telescope (VLT). The high spectral resolution observations (R=100,000) provide a wealth of information on the planet's orbit, mass, composition, and even on its atmospheric dynamics. The new observational strategy and data analysis techniques open up a whole world of opportunities. We therefore started an ESO large program using CRIRES to explore these, targeting both transiting and non-transiting planets in carbon monoxide, water vapour, and methane. Observations of the latter molecule will also serve as a test-bed for METIS, the proposed mid-infrared imager and spectrograph for the European Extremely Large Telescope.

description: Let $a,b,c,d$ be four vertices in a graph $G$. A \emph{$K_4$-minor rooted} at $a,b,c,d$ consists of four pairwise-disjoint pairwise-adjacent connected subgraphs of $G$, respectively containing $a,b,c,d$. We characterise precisely when $G$ contains a $K_4$-minor rooted at $a,b,c,d$ by describing six classes of obstructions, which are the edge-maximal graphs containing no $K_4$-minor rooted at $a,b,c,d$. The following two special cases illustrate the full characterisation: (1) A 4-connected non-planar graph contains a $K_4$-minor rooted at $a,b,c,d$ for every choice of $a,b,c,d$. (2) A 3-connected planar graph contains a $K_4$-minor rooted at $a,b,c,d$ if and only if $a,b,c,d$ are not on a single face.
