description: We give a new theoretical basis for examination of the presence of the Kerr black hole (KBH) or the Kerr naked singularity (KNS) in the central engine of different astrophysical objects around which astrophysical jets are typically formed: X-ray binary systems, gamma ray bursts (GRBs), active galactic nuclei (AGN), etc. Our method is based on the study of the exact solutions of the Teukolsky master equation for electromagnetic perturbations of the Kerr metric. By imposing original boundary conditions on the solutions so that they describe a collimated electromagnetic outflow, we obtain the spectra of possible {\em primary jets} of radiation, introduced here for the first time. The theoretical spectra of primary electromagnetic jets are calculated numerically. Our main result is a detailed description of the qualitative change of the behavior of primary electromagnetic jet frequencies under the transition from the KBH to the KNS, considered here as a bifurcation of the Kerr metric. We show that quite surprisingly the novel spectra describe linearly stable primary electromagnetic jets from both the KBH and the KNS. Numerical investigation of the dependence of these primary jet spectra on the rotation of the Kerr metric is presented and discussed.

Exact Histogram Specification Optimized for Structural Similarity

description: An exact histogram specification (EHS) method modifies its input image to have a specified histogram. Applications of EHS include image (contrast) enhancement (e.g., by histogram equalization) and histogram watermarking. Performing EHS on an image, however, reduces its visual quality. Starting from the output of a generic EHS method, we maximize the structural similarity index (SSIM) between the original image (before EHS) and the result of EHS iteratively. Essential in this process is the computationally simple and accurate formula we derive for SSIM gradient. As it is based on gradient ascent, the proposed EHS always converges. Experimental results confirm that while obtaining the histogram exactly as specified, the proposed method invariably outperforms the existing methods in terms of visual quality of the result. The computational complexity of the proposed method is shown to be of the same order as that of the existing methods. Index terms: histogram modification, histogram equalization, optimization for perceptual visual quality, structural similarity gradient ascent, histogram watermarking, contrast enhancement.

Subjects: subject: 530 Physik

description: Achieving high resolution under ultrahigh-vacuum conditions with the force microscope can be difficult for reactive surfaces, where the interaction forces between the tip and the samples can be relatively large. A force detection scheme that makes use of a modified cantilever beam and senses the force gradient through frequency modulation is described. The reconstructed silicon (111)-(7x7) surface was imaged in a noncontact mode by force microscopy with atomic resolution (6 angstroms lateral, 0.1 angstrom vertical).
Constructed Desire: Using Design to Address Notions of Contemporary Sexuality in the Western World

description: This body of work presents a series of design propositions that seek to address notions of contemporary sexuality in the Western world, particularly in urban North America and Europe. Our evolved sex and love drives find themselves confronted with an ever-changing cultural landscape where sexual norms are enforced and underly- ing instincts are sometimes used for the advancement of agendas and financial gain. Critical theorists and designers translate and expose the existence and operations of ideology, patriarchy, and the unconscious. Using a ‘research through design’ approach and pulling from attitudes and methodologies found in the realm of ‘critical design’ I present a sequence of explorations that are meant to act as proposals, as vessels through which people can reach their own interpretations and opinions about the influence of media culture on how we think about sex, how we have it, and how we talk about it.

description: Industrial separation and reaction processes mostly require more than one phase. Defined phase contact of solids (S), liquids (L), and gases (G) forms the physical backbone regarding process intensification and optimization. Novel reactor and contactor design for liquid-liquid operations in the Taylor-Couette Disc Contactor (TCDC) serve in optimizing the contact of two phases as for example in bubble columns or liquid-liquid extraction columns [1]. The Taylor-Couette Disc Contactor combines the advantages of a Taylor-Couette reactor (TCR) and a Rotating disc contactor (RDC). The toroidal Taylor vortexes are stabilized with rotor discs. This geometric design was optimized by CFD simulation and resulted in TCDC design recommendations [2]. The main differences between the RDC and the TCDC are that the TCDC does not need stator rings. The increased rotor disc and shaft diameter combined with optimal compartment height is sufficient to decrease axial backmixing in a stable flow regime without the presence of stator rings. The prevention of hydraulic deadzones due to missing static internals provides ideal conditions to process additional phases like solids or gases. In this work, stable and continuous operation up to four phases has been performed in a TCDC column and proofs the suitability for defined, stable multiphase contact in the TCDC.

Memory

description: This paper chronicles my thesis research into memory, place and painting. I focus my research on the disused homestead of Demetri Cabin on Saltspring Island, and use this paper to introduce the reader to the site. Using two distinctive voices, one narrative and one scholarly, my writing engages the reader in a lyrical tour of Demetri Cabin while simultaneously tracing my path between site and studio. In the first part of the document, I outline my early painted works and their connection to mediated technology. From here, I follow the conception and creation of Walking in the Dark Paintings, a body of work developed in direct response to Demetri Cabin. Finally, I end the paper by discussing my relationship to installation and theatricality, two elements that featured heavily in my thesis exhibition. Written from a reflective position, I use this paper to illuminate the network of references and meaning that brought together the mediums of sculpture and painting in my thesis installation, and ruminate on the success and intention of this gesture.

description: It is shown that the Lorentz force equation is equivalent to the auto-parallel condition $\,^L\nabla_{\dot{x}}\dot{x}=0$ of a linear connection $^L\nabla$ defined on a convenient pull-back vector bundle. By using a geometric averaging method, an associated {\it averaged Lorentz connection} $\langle\,^L\nabla\rangle$ and the corresponding auto-parallel equation are obtained. After this, it is shown that in the ultra-relativistic limit and for narrow one-particle probability distribution functions, the auto-parallel curves of $\langle\,^L\nabla\rangle$ remain {\it nearby} close to the auto-parallel curves of $^L\nabla$. Applications of this result in beam dynamics and plasma physics are briefly described.

description: We consider the early time cosmology of f(R) theories in Palatini formalism and study the conditions that guarantee the existence of homogeneous and isotropic models that avoid the Big Bang singularity. We show that for such models the Big Bang singularity can be replaced by a cosmic bounce without violating any energy condition. In fact, the bounce is possible even for pressureless dust. We give a characterization of such models and discuss their dynamics in the region near the bounce. We also find that power-law lagrangians with a finite number of terms may lead to non-singular universes, which contrasts with the infinite-series Palatini f(R) lagrangian that one needs to fully capture the effective dynamics of Loop Quantum Cosmology. We argue that these models could also avoid the formation of singularities during stellar gravitational collapse.

description: Alkaline direct ethanol fuel cells (ADEFCs) have gained much attention in the last years due to their use of alternative energy sources. Commercial carbon supported palladium and platinum catalysts were ex-situ characterized by means of cyclic voltammetry experiments for their application in ADEFCs. The activity for the ethanol oxidation reaction (EOR) of the Pd/C catalyst was analyzed and an electrochemical active surface area (ECSA) of 411 cm2 mg-1, an onset potential of 0.255 V and a maximum current density for the forward scan of 126 mA cm-2 was examined. In addition, the performance of the Pt/C catalyst for the oxygen reduction reaction (ORR) was investigated resulting in an onset potential of 0.95 V and a limiting current density of ‑3.68 mA cm‑2 at 2000 rpm. Moreover, in-situ characterization in a self-designed ADEFC was performed. Therefore, a membrane electrode assembly (MEA) was developed using the Pt/C catalyst as active cathode material, Pd/C as active anode material and a commercial fumasep® FAA-3-PK-130 as anion-exchange membrane. The results of the single cell tests showed that a humidified oxygen flow rate of 20 mL min-1 and an ethanol fuel flow rate of 200 mL min-1 are most optimal for a good performance of the fuel cell. A maximum power density of 0.4 mW cm-2 was achieved.

Anomalies in Universal Intensity Scaling in Ultrarelativistic Laser-Plasma Interactions

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Laser light incident on targets at intensities such that the electron dynamics is ultrarelativistic gives rise to a harmonic power spectrum extending to high orders and characterized by a relatively slow decay with the harmonic number m that follows a power law dependence, m^{-p}. Relativistic similarity theory predicts a universal value for p = 8/3 up to some cut-off m = m*. The results presented in this work suggest that under conditions in which plasma effects contribute to the emission spectrum, the extent of this contribution may invalidate the concept of universal decay. We report a decay with harmonic number in the ultrarelativistic range characterised by an index 5/3 < p < 7/3, significantly weaker than that predicted by the similarity model.

description: There are multiple reasons why the next generation of biological and medical studies require increasing numbers of samples. Biological systems are dynamic, and the effect of a perturbation depends on the genetic background and environment. As a consequence, many conditions need to be considered to reach generalizable conclusions. Moreover, human population and clinical studies only reach sufficient statistical power if conducted at scale and with precise measurement methods. Finally, many proteins remain without sufficient functional annotations, because they have not been systematically studied under a broad range of conditions. In this review, we discuss the latest technical developments in mass spectrometry (MS)-based proteomics that facilitate large-scale studies by fast and efficient chromatography, fast scanning mass spectrometers, data-independent acquisition (DIA), and new software. We further highlight recent studies which demonstrate how high-throughput (HT) proteomics can be applied to capture biological diversity, to annotate gene functions or to generate predictive and prognostic models for human diseases.

description: In this thesis, I outline a multimodal research project that investigates my relationship to the lower Fraser River from Yale BC to the mouth and takes up methods of physical exploration, conversation and drawing. My research questions include: As a fifth generation settler, woman, artist and forestry laborer, how might I form a respectful relationship to land and water in a moment of indigenous resurgence during the Anthropocene? And through representation, how might I contribute to the construction of landscape as a cultural medium? First, I briefly contextualize both my positionality and the Fraser River delta area, and then introduce a methodological framework that incorporates long-term place-based and embodied investigations including walking and swimming, and conversations with indigenous and non-indigenous people who share interests and hold knowledge about the river. These practices have been influenced by an understanding of land and water as having implicit agency and power far beyond their role as consumptive resources; and have been guided by an ethos of respect and reciprocity that draws on ideas imbedded in many indigenous research methodologies. I then introduce a co-emergent drawing practice that is linked to site-based investigations by the idea of wayfinding, and utilizes site-derived plant and mineral-based pigments. Included is a description of artistic process and formal elements of the work, a discussion about materiality as imbedded in ecological relationships, and a conversation about my choice to use halq’eméylem place-names to both indicate where the pigments were found and to honour the depth of cultural knowledge imbedded in the landscape of the lower Fraser River. This thesis defines a practice that takes up formal image making while engaging in the politics of place from a critical settler perspective. It describes a deep artistic investment, guided by a cyclical and iterative engagement with land, form, material, language, theory and intuition.

description: We report a femtosecond mid-infrared study of the broadband low-energy response of individually separated (6,5) and (7,5) single-walled carbon nanotubes. Strong photoinduced absorption is observed around 200 meV, whose transition energy, oscillator strength, resonant chirality enhancement and dynamics manifest the observation of quasi-1D intra-excitonic transitions. A model of the nanotube 1s-2p cross section agrees well with the signal amplitudes. Our study further reveals saturation of the photoinduced absorption with increasing phase-space filling of the correlated e-h pairs.

French language resources and the secondary school library, with recommendations for British Columbia
Creators: name: Herring, Walter A.
Publisher: name: University of British Columbia

description: Examination of educational literature reveals a wealth of suggested materials and procedures to provide independent study facilities for students of the sciences, social studies and English. Very little mention is made of library resources for students of French or other foreign languages. This thesis proposes to survey the present relationship between secondary school French teaching and school libraries in British Columbia, and to make recommendations for the future growth of libraries offering independent French language study facilities. From questionnaires completed by French teachers and school librarians across the province, summaries of their respective holdings were obtained. Typical situations could be described, although few consistent patterns of organization were found. The questionnaires were analyzed in three school-size groups: under 500 pupils, between 500 and 1000, and over 1000. As expected, the larger schools have an advantage in obtaining most types of supplementary materials and equipment. With British Columbia's present situation clearly in mind, some attention is given to the relationships, personal and organizational, between French teachers and librarians. From recent literature and a visit to a leading American high school, a modern, realistic role for both language department and library resources is proposed. The thesis examines audiovisual learning in some detail. It was found through the questionnaires that many libraries are prepared to adopt the "materials centre" concept which implies a wide variety of electronic and other non-print resources. Some cautionary statements are directed to librarians after a discussion of the limited ability of modern technologies to serve students of French in secondary school library settings. Appendices explore the usefulness of the Bell and Howell Language Master, an audio-instructional device which purports to have applications to all learning tasks. Pupils who used the Language Master extensively during a two-week period made progress similar to that of a control group who remained under regular classroom instruction. A further attempt to use the machine for individual remedial study revealed some apparent deficiencies in such an application. It is concluded that it is of minimal value for language training, and recommendations are made for further research. Finally, a list of reading materials related to French courses is offered as an aid to teachers and librarians.

description: In this paper, we study matrix valued positive definite functions on a unimodular group. We generalize two important results of Godement on square integrable positive definite functions to matrix valued square integrable positive definite functions. We show that a matrix-valued continuous $L^2$ positive definite function can always be written as a convolution of a $L^2$ positive definite function with itself. We also prove that, given two $L^2$ matrix valued positive definite functions $Φ$ and $Ψ$, $\int_G Trace(Φ(g) \bar{Ψ(g)}^t) d g \geq 0$. In addition this integral equals zero if and only if $Φ* Ψ=0$. Our proofs are operator-theoretic and independent of the group.

description: Background The Dermatophagoides pteronyssinus molecule Der p 23 is a major allergen whose clinical relevance has been shown in cross-sectional studies. We longitudinally analysed the trajectory of Der p 23-specific IgE antibody (sIgE) levels throughout childhood and youth, their early-life determinants and their clinical relevance for allergic rhinitis and asthma. Methods We obtained sera and clinical data of 191 participants of the German Multicentre Allergy Study, a prospective birth cohort. Serum samples from birth to 20 years of age with sIgE reactivity to Der p 23 in a customised semiquantitative microarray were newly analysed with a singleplex quantitative assay. Early mite exposure was assessed by measuring the average content of Der p 1 in house dust at 6 and 18 months. Results Der p 23-sIgE levels were detected at least once in 97/191 participants (51%). Prevalence of Der p 23 sensitisation and mean sIgE levels increased until age 10 years, plateaued until age 13 years and were lowest at age 20 years. Asthma, allergic rhinitis (AR) and atopic dermatitis (AD) were more prevalent in Der p 23-sensitised children, including those with monomolecular but persistent sensitisation (11/97, 11%). A higher exposure to mites in infancy and occurrence of AD before 5 years of age preceded the onset of Der p 23 sensitisation, which in turn preceded a higher incidence of asthma. Conclusions Der p 23 sensitisation peaks in late childhood and then decreases. It is preceded by early mite exposure and AD. Asthma and AR can occur in patients persistently sensitised to Der p 23 as the only mite allergen, suggesting the inclusion of molecular testing of Der p 23-sIgE for subjects with clinical suspicion of HDM allergy but without sIgE to other major D.pt. allergens.

description: Several projects are concentrating their efforts on opening the high energy neutrino window on the Universe with km-scale detectors. The detection principle relies on the observation, using photomultipliers, of the Cherenkov light emitted by charged leptons induced by neutrino interactions in the surrounding detector medium. In the Northern hemisphere, while the pioneering Baikal telescope, has been operating for 10 years, most of the activity now concentrates in the Mediterranean sea. Recently, the Antares collaboration has completed the construction of a 12 line array comprising ~ 900 photomultipliers. In this paper we will review the main results achieved with the detectors currently in operation in the Northern hemisphere, as well as the R&D efforts towards the construction of a large volume neutrino telescope in the Mediterranean.

description: We derive the axis ratio distribution of X-ray clusters using the XMM-Newton catalogue (Snowden et al. 2008). By fitting the contour lines of the X-ray image by ellipses, we confirm the X-ray distribution is well approximated by the elliptic distribution with a constant axis ratio and direction. We construct a simple model describing the axis ratio of the X-ray gas assuming the hydrostatic equilibrium embedded in the triaxial dark matter halo model proposed by Jing & Suto (2002) and the hydrostatic equilibrium. We find that the observed probability density function of the axis ratio is consistent with this model prediction.

description: The holographic principle, considered in a semiclassical setting, is shown to have direct consequences on physics at a fundamental level. In particular, a certain relation is pointed out to be the expression of holography in basic thermodynamics. It is argued moreover that through this relation holography can be recognized to induce gravity, and an expression for the gravitational lensing is obtained in terms of entropy over wavelength of black-body radiation, or, at a deeper level, in terms of maximum entropy over associated space to the elementary bit of information.

description: We report an experimental and theoretical investigation of the frequency-dependent effective mass, $\tilde{M}(ω)$, of loose granular particles which occupy a rigid cavity to a given filling fraction, the remaining volume being air of differing humidities. This allow us to study the mechanisms of elastic response and attenuation of acoustic modes in granular media. We demonstrate that this is a sensitive and direct way to measure those properties of the granular medium that are the cause of the changes in acoustic properties of structures containing grain-filled cavities. Specifically, we apply this understanding to the case of the flexural resonances of a rectangular bar with a grain-filled cavity within it. The dominant features of $\tilde{M}(ω)$ are a sharp resonance and a broad background, which we analyze within the context of simple models. We find that: a) These systems may be understood in terms of a height-dependent and diameter-dependent effective sound speed ($\sim 100-300$ m/s) and an effective viscosity ($\sim 5\times 10^4$ Poise). b) There is a dynamic Janssen effect in the sense that, at any frequency, and depending on the method of sample preparation, approximately one-half of the effective mass is borne by the side walls of the cavity and one-half by the bottom. c) By performing experiments under varying humidity conditions we conclude that, on a fundamental level, damping of acoustic modes is dominated by adsorbed films of water at grain-grain contacts in our experiments, not by global viscous dampening. d) There is a monotonically increasing effect of humidity on the dampening of the fundamental resonance within the granular medium which translates to a non-monotonic, but predictable, variation of dampening within the grain-loaded bar.

description: The purpose of this study was to analyze the psychological characteristics underlying Chinese parents’ behaviors in using child car seats and to understand their decision-making processes. Based on the theory of planned behavior (TPB), three extended variables of perceived accident severity, perceived benefits, and perceived barriers were introduced. From the perspective of social psychology, the psychological factors that influence parents’ use of child car seats and their interrelationships were explored. A questionnaire was designed to collect data, including information on demographic characteristics, basic components of the TPB, and relevant extension variables. Using on online survey, 585 valid questionnaires were collected. Structural equation modeling was used to calibrate the data, and multiple group analysis was performed on the demographic variables. The extended TPB can effectively explain and predict parents’ behaviors when using children’s car seats. The results of the model show that parents’ positive attitudes toward child safety seats (CSSs), others’ recognition of their own use and perceptual control of the use of CSSs increase their willingness to use CSSs. Parents’ willingness to use has a positive impact on the use of CSSs. Additionally, for the three extended variables introduced, perceived benefit significantly promoted parental intention and behavior to use CSS for children; perceived barriers significantly reduced parental use of CSS; and perceived accident severity had no significant effect on parental use of CSS. This study established the validity of the extended TPB model in predicting parents’ behaviors in using car seats for their children. In addition, the current findings may provide a theoretical basis for policy development to promote CSS use.

Vor allem die hohen spezifischen Kosten für eine den geltenden gesetzlichen Regelungen entsprechende Lösung haben zu einer weiten Palette an Lösungsmöglichkeiten geführt, die von zentralen bis zu dezentralen und von „konventionellen“ bis zu „alternativen“ Systemen reichen. Leider gibt es für diese ländlichen Gebiete kein Patentrezept, vielmehr muß für jeden Einzelfall die angepaßte Optimallösung gesucht werden. Dabei ist der Einsatz objektivierbarer und nachvollziehbarer Entscheidungskriterien sehr hilfreich und die Einbindung aller Beteiligten Grundvoraussetzung für eine breite und nachhaltige Akzeptanz der schließlich zur Ausführung gelangenden Variante.

description: Electrical resistivity tomography (ERT) is an important method for exploring oil and gas formations, mineral deposits, and groundwater resources. However, most ERT instruments have limitations such as complicated human–computer interaction, few measurement parameters, difficulties in remote monitoring, and lack of four-dimensional (4D) exploration functions. To overcome these limitations, in this study we proposed and developed software for a remote control 4D ERT system based on a cloud platform and Internet of Things (IoT) technology. Specifically, acquisition device control, channel and control, acquisition control, and remote monitoring systems were designed, with various modules being debugged and optimized multiple times. The system is equipped with a 4G module, through which the collected data are transmitted to the cloud platform to realize real-time, stable, and long-distance data acquisition and transmission. Furthermore, the system realizes remote monitoring, real-time measurement, and other functions via the cloud and IoT technology, thereby providing strong technical support for achieving 4D exploration. The developed system was empirically evaluated by applying it to explore the Gequ Landslide area in Jainca County, Qinghai Province, China. The exploration results indicate that the system software has stable functions and high intelligence; thus it satisfies the requirements for field exploration.

description: We exhibit the rich structure of the set of correlated equilibria by analyzing the simplest of polynomial games: the mixed extension of matching pennies. We show that while the correlated equilibrium set is convex and compact, the structure of its extreme points can be quite complicated. In finite games the ratio of extreme correlated to extreme Nash equilibria can be greater than exponential in the size of the strategy spaces. In polynomial games there can exist extreme correlated equilibria which are not finitely supported; we construct a large family of examples using techniques from ergodic theory. We show that in general the set of correlated equilibrium distributions of a polynomial game cannot be described by conditions on finitely many moments (means, covariances, etc.), in marked contrast to the set of Nash equilibria which is always expressible in terms of finitely many moments.

description: Helicobacter pylori is a pathogen that colonizes the stomach and causes chronic gastritis. Helicobacter pylori can colonize deep inside gastric glands, triggering increased R-spondin 3 (Rspo3) signaling. This causes an expansion of the "gland base module," which consists of self-renewing stem cells and antimicrobial secretory cells and results in gland hyperplasia. The contribution of Rspo3 receptors Lgr4 and Lgr5 is not well explored. Here, we identified that Lgr4 regulates Lgr5 expression and is required for H. pylori-induced hyperplasia and inflammation, while Lgr5 alone is not. Using conditional knockout mice, we reveal that R-spondin signaling via Lgr4 drives proliferation of stem cells and also induces NF-kappa B activity in the proliferative stem cells. Upon exposure to H. pylori, the Lgr4-driven NF-kappa B activation is responsible for the expansion of the gland base module and simultaneously enables chemokine expression in stem cells, resulting in gland hyperplasia and neutrophil recruitment. This demonstrates a connection between R-spondin-Lgr and NF-kappa B signaling that links epithelial stem cell behavior and inflammatory responses to gland-invading H. pylori.

description: Recent progress in theories of quantum information has determined nonclassical correlation defined differently from widely-used entanglement as an important property to evaluate computation and communication with mixed quantum states. We introduce an operational method to detect nonclassical correlation of bipartite systems. In this method, we use particular maps analogous to the well-established entanglement witnesses. Thus, the maps are called nonclassical correlation witness maps. Furthermore, it is proved that such a map can be generally decomposed so that a single-run experiment is feasible for implementation in bulk-ensemble systems.

description: Die primäre Aufgabe einer modernen, ökologisch orientierten Wasserwirtschaft liegt in der Sicherung und/oder Wiederherstellung der Lebensräume für fließgewässertypische Organismen. Ziel ist die Erhaltung letzter verbliebener natürlicher Gewässerabschnitte und die Verbesserung und Wiederherstellung der standortstypischen ökologischen Funktion beeinträchtigter Fließgewässer. Eine erfolgte Annäherung an einen naturnäheren Zustand als Folge einer Gewässerumgestaltung wurde im Rahmen einer vergleichenden Bestandsanalyse an Referenzstrecken nachgewiesen. Die modellmäßige Simulation der abiotischen Verhältnisse maßgeblicher, lebensraumbeschreibender Parameter eines Fließgewässers und die Verknüpfung mit den Habitatpräferenzen unterschiedlicher Arten und Altersstadien ermöglicht die Beschreibung des zur Verfügung stehenden, nutzbaren Lebensraumes für Fließgewässerorganismen. Aus diesen Ergebnissen, dargestellt an einem Fallbeispiel, sind für unterschiedliche Gestaltungsvarianten im Rahmen einer Maßnahmenumsetzung Verbesserungen der organismischen Besiedlung entsprechend der natürlichen Ausprägung des betreffenden Gewässertyps möglich. Dadurch ist die größtmögliche Annäherung einer Gewässerstrecke an ihre standortstypische ökologische Funktion gewährleistet.

description: Telomeres, the end fragments of chromosomes, play key roles in cellular proliferation and senescence. Here we characterize the genetic architecture of naturally occurring variation in leukocyte telomere length (LTL) and identify causal links between LTL and biomedical phenotypes in 472,174 well-characterized UK Biobank participants. We identified 197 independent sentinel variants associated with LTL at 138 genomic loci (108 new). Genetically determined differences in LTL were associated with multiple biological traits, ranging from height to bone marrow function, as well as several diseases spanning neoplastic, vascular and inflammatory pathologies. Finally, we estimated that, at the age of 40 years, people with an LTL >1 s.d. shorter than the population mean had a 2.5-year-lower life expectancy compared with the group with ≥1 s.d. longer LDL. Overall, we furnish new insights into the genetic regulation of LTL, reveal wide-ranging influences of LTL on physiological traits, diseases and longevity, and provide a powerful resource available to the global research community.
