description: The recent literature suggests that an evolutionary dichotomy exists for early-type galaxies (Es and S0s, ETGs) whereby their central photometric structure (cuspy versus core central luminosity profiles), and figure of rotation (fast (FR) vs. slow (SR) rotators), are determined by whether they formed by "wet" or "dry" mergers. We consider whether the mid infrared (MIR) properties of ETGs, with their sensitivity to accretion processes in particular in the last few Gyr (on average z < 0.2), can put further constraints on this picture. We investigate a sample of 49 ETGs for which nuclear MIR properties and detailed photometrical and kinematical classifications are available from the recent literature. In the stellar light cuspy/core ETGs show a dichotomy that is mainly driven by their luminosity. However in the MIR, the brightest core ETGs show evidence that accretions have triggered both AGN and star formation activity in the recent past, challenging a "dry" merger scenario. In contrast, we do find, in the Virgo and Fornax clusters, that cuspy ETGs, fainter than M$_{K_s}=-24$, are predominantly passively evolving in the same epoch, while, in low density environments, they tend to be more active. A significant and statistically similar fraction of both FR (38$^{+18}_{-11}$\%) and SR (50$^{+34}_{-21}$\%) shows PAH features in their MIR spectra. Ionized and molecular gas are also frequently detected. Recent star formation episodes are then a common phenomenon in both kinematical classes, even in those dominated by AGN activity, suggesting a similar evolutionary path in the last few Gyr. MIR spectra suggest that the photometric segregation between cuspy and core nuclei and the dynamical segregation between FR and SR must have originated before z~0.2.

description: Lepisanthes rubiginosa (Roxb.) Leenh (LRL), a wild fruit of Thailand, was characterized for phytochemicals including phenolic acids, flavonoids, carotenoids, anthocyanins, organic acids, and sugars. To process it, three drying methods were investigated, namely, freeze drying (FD), hot-air drying (HD), and sun drying (SD), which affected chemical components and antioxidant activities. The predominant phenolic acids and flavonoids were p-hydroxybenzoic acid, chlorogenic acid, vanillic acid, quercetin, rutin, and myricetin. Remarkably high amounts of lycopene (158 mg/100g db) and cyanidin-3-O-glucoside (2005 mg/100g db) were observed. Flavonoids, carotenoids, and anthocyanin were decreased by all drying methods. Overall, FD was considered to be the most suitable for drying LRL fruit. Fructose conversion to mannitol during drying was explored by FTIR spectroscopy analysis in FD and HD samples. This study has revealed new information about LRL fruits, which could be a potential source of bioactive compounds; an appropriate drying method is suggested for further applications.
Analysis The effect of unequal force application on A.A LRT disc brake during emergency brake

Publisher: name: Zenodo
Year: 2016

description: A train disc brake system is used to perform three basic functions, i.e. to reduce speed of a vehicle, to maintain its speed when travelling downhill and to completely stop the vehicle. During these braking events, the disc brake may suffer of temperature, deformation and stress issues. It is quite sometimes that the disc brake components fail structurally and/or having severe deformation on the pad. Thus, this paper aims to examine stress concentration, structural deformation and contact pressure of brake disc and pads during braking event by employing commercial finite element software, ANSYS and CATIA for modelling purpose with considering the effect of unequal pressure application on the two opposite side of the disc which are developed due to brake line corrosion, calliper sticking, failure of piston seal, variation of rotor thickness and also failure of calliper bolts.

description: The universality of locality is a long-standing debate that has endured in psycholinguistics in spite of the challenges. The non-local preference of attachment in Relative Clauses (RCs) with double antecedent (DP1-of-DP2-RC) reported in a subset of languages (i.e. Spanish) represented an important challenge that locality-based accounts had to address. The forces responsible for attachment preferences turned out to be multifactorial, with relevant roles for prosody, referentiality, lexical semantics and Pseudo-Relative availability. In the present eye-tracking study, we explore the timing of disambiguation in Spanish DP1-of-DP2-RC structures placed in preverbal and post-verbal positions, while also controlling for the previously mentioned influencing factors. Our results are straightforward: an early processing cost arises when the RC is disambiguated non-locally, irrespective of the position. The implications of this work contribute to a better understanding of parsing processes and suggest that locality is at the centre of the forces that influence RC attachment.

description: In examining price-quantity relationships of eight cuts of pork (loins, hams, butts, spareribs, sausage, picnics, bacon, and lunch meat); and three types of outlets (chain, independent, and convenience), equation results of a specific cut were found not to differ greatly by retail outlet. Equations of retail price predictions for each of the 24 combinations are presented, and various data series, not generally available are included in the study. Appendixes to the main text provide more complete examination of derivation of data, a brief look at the theory involved, and estimates of elasticity. Data derivations include quantities by cut as they flow through nonretail consumer outlets (hotel restaurants, institutions, and other away-from-home eating places). A shift in pork demand between 1965 and 1966 was noted, and the fact that poultry was a closer competitor of pork than was beef. The study also showed differences in demand among pork cuts, and examined other areas such as sales trends by types of retail outlet

description: This study examined factors that determine savings in Nigeria. Secondary data were sourced from Central Bank of Nigeria (CBN) Statistical Bulletin and Annual Report of Nigerian Bureau of statistics from 1990 – 2023.Total savings to Gross Domestic Product was modeled as the function of savings rate, real gross domestic product, public expenditure as percentage of capital expenditure to gross domestic product, economic openness as percentage of export-import to gross domestic product, financial deepening as private sector credit to gross domestic product, inflation rate and exchange rate. The Ordinary Least Square properties of co-integration, Augmented Dickey Fuller Unit Root and Error correction model were used to examine the long and the short run relationship that exists among the variables. R2, F-statistics and T-statistics were used to determine the extent to which the independent variables affect the dependent variable. The study found that 74.1 and 64.8 percent variation in total savings were explained by variation in the variables as formulated, the model was statistically significant based on F-statistic and probability while the Durbin Watson proved the absence of serial autocorrelation. It recommends that Policies, strategies and measures should be devising by the regulatory authorities to enhance the operational efficiency of the financial system through effective regulations to achieve set goals, Regulatory structure and framework of the financial system should be integrated with macroeconomic objectives such as savings mobilizations and that the regulatory bodies in the financial system should be well managed to avoid conflict of policies with other macroeconomic objectives such as saving mobilization.

description: In an uncoordinated network, the link performance between the devices might degrade significantly due to the interference from other links in the network sharing the same spectrum. As a solution, in this study, the concept of partially overlapping tones (POT) is introduced. The interference energy observed at the victim receiver is mitigated by partially overlapping the individual subcarriers via an intentional carrier frequency offset between the links. Also, it is shown that while orthogonal transformations at the receiver cannot mitigate the other-user interference without losing spectral efficiency, non-orthogonal transformations are able to mitigate the other-user interference without any spectral efficiency loss at the expense of self-interference. Using spatial Poisson point process, a tractable bit error rate analysis is provided to demonstrate potential benefits emerging from POT.

description: Nonlocal problems for higher-order elliptic operators in dihedral and plane angles are considered. The Green formula is obtained, which leads to adjoint problems that take the form of nonlocal transmission problems in dihedral and plane angles. This allows us to establish necessary conditions of Fredholm solvability and sufficient conditions of one-valued solvability for nonlocal problems in dihedral angles.

description: Socioeconomic and food consumption profiles of families in the Expanded Food and Nutrition Education Program (EFNEP) are presented according to their food assistance status during 1969. This includes profiles of food stamp and food distribution program participants, eligible nonparticipants, and ineligible families. EFNEP is administered by the U.S. Department of Agriculture's Extension Service. Significant differences in socioeconomic characteristics and food consumption practices existed among EFNEP families according to their food assistance program status. Among participants and those eligible but not participating, food stamp families fared best in both economic and food consumption characteristics. Food assistance recipients and eligible nonparticipants ranked below ineligibles in economic and food consumption characteristics. Regression analysis identified significant factors contributing to variations in food expenditures and family income. Income and family size were among the variables significantly related to food expenditures, while education and family size were among those significantly related to family income.
Microscale heat transfer in a free jet against a plane surface

description: A new two-layer model has been proposed to study microscale heat transfer associated with a developing flow boundary layer. As an example, a cold, microscale film of liquid impinging on an isothermal hot, horizontal surface has been investigated. The boundary layer is divided into two regions: a micro layer at microscale away from the surface and a macro layer at macroscale away from the surface. An approximate solution for the velocity and temperature distributions in the flow along the horizontal surface is developed, which exploits the hydrodynamic similarity solution for microscale film flow. The approximate solution may provide a valuable basis for assessing microscale flow and heat transfer in more complex settings.

description: Vagus nerve stimulation (VNS) represents a long-term adjunctive treatment option in patients with difficult-to-treat depression (DTD). Anti-inflammatory effects have been discussed as a key mechanism of action of VNS. However, long-term investigations in real-world patients are sparse. In this naturalistic observational study, we collected data on cytokines in peripheral blood in n = 6 patients (mean age 47.8) with DTD and VNS treatment at baseline and at 6 months follow-up. We have identified clusters of peripheral cytokines with a similar dynamic over the course of these 6 months using hierarchical clustering. We have investigated cytokine changes from baseline to 6 months as well as the relationship between the cytokine profile at 6 months and long-term response at 12 months. After 6 months of VNS, we observed significant correlations between cytokines (p < 0.05) within the identified three cytokine-pairs which were not present at baseline: IL(interleukin)-6 and IL-8; IL-1β and TNF-α; IFN-α2 and IL-33. At 6 months, the levels of all the cytokines of interest had decreased (increased in non-responders) and were lower (5–534 fold) in responders to VNS than in non-responders: however, these results were not statistically significant. VNS-associated immunomodulation might play a role in long-term clinical response to VNS.

description: Der erste Teil der vorliegenden Dissertation umfasst Untersuchungen zur Totalsynthese des Sesquiterpens Presilphiperfolan-1-ol. Die Naturstoffklasse zeichnet sich durch ein ungewöhnliches kompaktes Trizykloundecan-Grundgerüst aus, das als Grundstruktur für den Aufbau vieler weiterer natürlicher Sequiterpene dient. Eine Gold(I)-katalysierte Pinakolkaskadenreaktion als Schlüsselschritt ermöglichte den Aufbau der bizyklischen Hydropentalen-Einheit des Naturstoffs in korrekter relativer Steroeokonfiguration. Außerdem konnten mit dieser und einer NIS-vermittelten Variante die syn-selektive Carbozyklisierung von 6-Brom- und 6-Chlor-1,5-Eninen zu bizyklischen Vinylhalogeniden demonstriert werden. Diese Methode konnte zur Bildung des synthetisch herausfordernden Trizyklus mittels Heck-Reaktion angewendet werden. Der zweite Teil der Dissertation setzt sich mit der Synthese von Estradiolderivaten für die Radionuklidtherapie auseinander und wurde in Kooperation mit Prof. Dr. Schomäcker (AG Radiochemie, Radiopharmazie und Strahlenbiologie, Uniklinik Köln) durchgeführt. Die Entwicklung neuer Radiopharmaka für die moderne Radionuklidtherapie bei Brustkrebs stand hierbei im Fokus. Durch Affinitätsmessungen der synthetisierten iodierten Estradiolderivate wurden Struktur-/Wirkungsbeziehungen am Estrogenrezeptor Alpha ermittelt. Neben der Derivatisierung der 17-Alpha-Position wurden Substiutionen mit alkylischen und fluorierten Bausteinen in 11-Beta-Position vorgenommen.

description: Classical novae are expected to contribute to the 1809-keV Galactic $γ$-ray emission by producing its precursor $^{26}$Al, but the yield depends on the thermonuclear rate of the unmeasured $^{25}$Al($p,γ$)$^{26}$Si reaction. Using the $β$ decay of $^{26}$P to populate the key $J^π=3^+$ resonance in this reaction, we report the first evidence for the observation of its exit channel via a $1741.6 \pm 0.6 (\textrm{stat}) \pm 0.3 (\textrm{syst})$ keV primary $γ$ ray, where the uncertainties are statistical and systematic, respectively. By combining the measured $γ$-ray energy and intensity with other experimental data on $^{26}$Si, we find the center-of-mass energy and strength of the resonance to be $E_r = 414.9 \pm 0.6(\textrm{stat}) \pm 0.3 (\textrm{syst}) \pm 0.6(\textrm{lit.})$ keV and $ωγ= 23 \pm 6 (\textrm{stat})^{+11}_{-10}(\textrm{lit.})$ meV, respectively, where the last uncertainties are from adopted literature data. We use hydrodynamic nova simulations to model $^{26}$Al production showing that these measurements effectively eliminate the dominant experimental nuclear-physics uncertainty and we estimate that novae may contribute up to 30% of the Galactic $^{26}$Al.

description: This document is related to implementation of Task 4.2 ‘Micro-beam upgrade at RBI Accelerator Facility’. The aim is to upgrade the two existing ion micro-beam stations by providing a precise motorized positioning system with the beam current control and Device Under Test (DUT)  position monitor, as well as to demonstrate the sample cooling option for the ‘old’ micro-beam station. These upgrades require the necessity for remote control of the various parameters, such as the sample illumination and positioning in front of the ion beam, the ion beam focusing and current control, leading to the development of an integrated control system, using the home made SPECTOR DAQ and Experimental Physics and Industrial Control System (EPICS) which enables not only the fine setting of various options at the end-station but in addition, also the parallel control of accelerator parameters and logging.

description: Entanglement, the essential resource in quantum information processing, should be witnessed in many tasks such as quantum computing and quantum communication. The conventional entanglement witness method, relying on an idealized implementation of measurements, could wrongly conclude a separable state to be entangled due to imperfect detections. Inspired by the idea of a time-shift attack, we construct an attack on the conventional entanglement witness process and demonstrate that a separable state can be falsely identified to be entangled. To close such detection loopholes, based on a recently proposed measurement-device-independent entanglement witness method, we design and experimentally demonstrate a measurement-device-independent entanglement witness for a variety of two-qubit states. By the new scheme, we show that an entanglement witness can be realized without detection loopholes.

description: Pedestrian simulations are used to tackle civil engineering problems in transport infrastructures and are a valuable tool to efficiently identify hotspots and potentially dangerous bottlenecks in different evacuation scenarios.
 To correctly assess and evaluate experimental and simulation data, swift analysis and comprehensive visualization are paramount. In this talk, we present a platform-independent visual tool for interactive and explorative analysis of pedestrian dynamics and investigation of new methods for quantification of safety-relevant insights of the crowd with a focus on time-performance and interactivity. The project centers around the motivation to extract from a single trajectory dataset as many useful insights as possible with the possibility to extend its functionality to generate statistics based on several trajectories.
 The dashboard consumes one trajectory file and one geometry file and produces numerous analytics. PedDashboard can be used easily without prior installation https://go.fzj.de/dashboard and is open-sourced on GitHub https://github.com/PedestrianDynamics/dashboard.

description: One way in which the human immunodeficiency virus (HIV-1) replicates within a host is by infecting activated CD4+ T-cells, which then produce additional copies of the virus. Even with the introduction of antiretroviral drug therapy, which has been very successful over the past decade, a large obstacle to the complete eradication of the virus is the presence of viral reservoirs in the form of latently infected CD4+ T-cells. We consider a model of HIV infection that describes T-cell and viral interactions, as well as, the production and activation of latently infected T-cells. Upon determining equilibrium states of the latent cell model, the local and global asymptotic behavior of solutions is examined, and the basic reproduction number of the system is computed to be strictly less than that of the corresponding three-component model, which omits the effects of latent infection. In particular, this implies that a wider variety of parameter values will lead to viral eradication as $t \to \infty$ due to the appearance of latent CD4+ T-cells. With this realization we discuss possible alternative notions for eradication and persistence of infection other than traditional tools. These results are further illustrated by a number of numerical simulations.

description: Aufgrund des gestiegenen Integrationsniveaus der Windenergie sind Windkraftanlagen inzwischen systemrelevante Komponenten der Energieversorgung.
 Zur Gewährleistung der Netzstabilität insbesondere während eines symmetrischen oder asymmetrischen Spannungseinbruchs müssen Windkraftanlagen den Netzfehler durchfahren und die Netzspannung durch spannungshebende Blindstromeinspeisung stützen.
 In der vorliegenden Arbeit wird die Entwicklung und Implementierung der Fähigkeit eines netzseitigen Vollumrichters einer drehzahlvariablen Windkraftanlage auf Basis eines Synchrongenerators zum Durchfahren von Netzfehlern thematisiert.
 Darüber hinaus wird ein Laborprüfstand als Entwicklungs- und Testumgebung auf Grundlage eines umrichterbasierten Kurzschlussemulators konzipiert und realisiert.
description: Due to the increased power penetration level of wind energy, wind turbines are now system-relevant components of the power supply.
 To ensure grid stability, especially during a symmetrical or asymmetrical voltage dip, wind turbines must provide low voltage ride through (LVRT) capability with simultaneous dynamic voltage support ability by feeding reactive currents.
 In this thesis, the development and implementation of the LVRT-capability of a grid-side full power converter of a variable-speed wind turbine based on a synchronous generator is discussed.
 In addition, an inverter based voltage sag generator as a laboratory test bench is designed.

description: To operate successfully in this credit card industry, various kinds of credit cards are offered to distinct user groups. This empirical study is conducted in Malaysia, and it examines the features of different types of credit card available. By using descriptive and one-way ANOVA test, this study analyses data of 234 credit cards which were collected from ringgitplus.com and imoney.my websites. The cards are categorised based on the usage purpose like airline tickets, insurance, dining, entertainment, fuel, lifestyle, groceries, shopping, utilities healthcare and general use. In total thirteen features are analysed for all of these cards. The findings show there is no significant difference in the purpose of cards based on the features of interest and profit rate, balance transfer annual charge, annual fees, annual fees for supplementary card, late payment, late payment maximum fees, cash withdrawal charges fees, minimum annual income, minimum age for primary cards, maximum age for primary cards, and minimum age for supplementary cards. However, only two features are statistically significant among the cards, these being cash back and interest rate on cash withdrawal. The findings will provide important insights for business managers, credit card users, and other policymakers regarding features and market segmentation in the credit card industry in Malaysia.

Dies gilt umso mehr für die Landtage und ihre Abgeordneten. Um sich dennoch europapolitisch einzubringen, stehen ihnen informelle Wege offen. Der Beitrag untersucht die Netzwerkaktivitäten österreichischer Landtagsabgeordneter in EU-Fragen: Mit welchen politischen Akteuren pflegen sie Kontakt, zu welchem Zweck und wie häufig? Gestützt auf Daten einer standardisierten Abgeordnetenbefragung zeigen wir, dass die eigene Region auch in EU-Angelegenheiten der primäre politische Bezugsrahmen der Landtagsabgeordneten bleibt, interparlamentarische Vernetzung auf allen politischen Ebenen eine wichtige Rolle spielt und die Abgeordneten Kontakte hauptsächlich zum Erhalt politisch bewerteter Informationen nutzen. Wir argumentieren, dass Ressourcen wichtige Erklärungsfaktoren für Unterschiede zwischen den Abgeordneten im Ausmaß diesbezüglicher Kontakte darstellen.

description: A significant amount of U.S. farmland, in terms of both acreage and total, market value, is rented. There is wide variation, however, depending on farm size and type of enterprise. Reliance on leasing increases with size of operation. Compared with owned land, a higher percentage of all rented farmland is in the larger farms. Tenure patterns vary considerably by type of farm, with leasing being most important in cash grain enterprises. These relationships suggest that if the trend toward increasing farm size continues, an even higher percentage of all rented land will be in the larger farms. This implies greater reliance on part-owner operations, particularly among farming operations that require large acreages. Estimates are based on the 1969 Census of Agriculture and pertain chiefly to farms with gross annual receipts of $2,500 or more.

description: We study theoretically in the present work the self-assembly of molecules in an open system, which is fed by monomers and depleted in partial or complete clusters. Such a scenario is likely to occur for example in the context of viral self-assembly. We provide a general formula for the mean-field size distribution which is valid both at equilibrium in a closed system, and in the stationary state in an open system. This allows us to explore in a simple way out-of-equilibrium features for self-assembly and compare them to equilibrium properties. In particular, we identify a region of parameter space for which the out-of-equilibrium size distribution in the presence of external fluxes is equal to the equilibrium size distribution in the absence of external fluxes, up to a constant renormalization factor. The range of validity of this result and its consequences are discussed.

description: Mathematical modeling of biological systems is crucial to effectively and efficiently developing treatments for medical conditions that plague humanity. Often, systems of ordinary differential equations are a traditional tool used to describe the spread of disease within the body. We consider the dynamics of the Human Immunodeficiency Virus (HIV) in vivo during the initial stage of infection. In particular, we examine the well-known three-component model and prove the existence, uniqueness, and boundedness of solutions. Furthermore, we prove that solutions remain biologically meaningful, i.e., are positivity preserving, and perform a thorough, local stability analysis for the equilibrium states of the system. Finally, we incorporate random coefficients within the model and obtain numerical results to predict the probability of infection given the transmission of the virus to a new individual.
Cooperative Compressive Power Spectrum Estimation

description: We examine power spectrum estimation from wide-sense stationary signals received at different wireless sensors. We organize multiple sensors into several groups, where each group estimates the temporal correlation only at particular lags, which are different from group to group. A fusion centre collects all the correlation estimates from different groups of sensors, and uses them to estimate the power spectrum. This reduces the required sampling rate per sensor. We further investigate the conditions required for the system matrix to have full column rank, which allows for a least-squares reconstruction method.

description: The superconductivity precursor phenomena in high temperature cuprate superconductors was studied by direct measurements of superconducting condensate with the use of the $c$-axis optical conductivity of YBa$_{2}$(Cu$_{1-x}$Zn$_{x}$)$_{3}$O$_{y}$ for several doping levels ($p$) as well as for several Zn-concentrations. Both of the real and imaginary part of the optical conductivity clearly showed that the superconducting carriers persist up to the high temperatures $T$$_{p}$ that is higher than the critical temperature $T$$_{c}$ but lower than the pseudogap temperature $T$$^{\ast}$. $T$$_{p}$ increases with reducing doping level like $T$$^{\ast}$, but decreases with Zn-substitution unlike $T$$^{\ast}$.

description: In a multitude of life's processes, cilia and flagella are found indispensable. Recently, the biflagellated chlorophyte alga Chlamydomonas has become a model organism for the study of ciliary coordination and synchronization. Here, we use high-speed imaging of single pipette-held cells to quantify the rich dynamics exhibited by their flagella. Underlying this variability in behaviour, are biological dissimilarities between the two flagella - termed cis and trans, with respect to a unique eyespot. With emphasis on the wildtype, we use digital tracking with sub-beat-cycle resolution to obtain limit cycles and phases for self-sustained flagellar oscillations. Characterizing the phase-synchrony of a coupled pair, we find that during the canonical swimming breaststroke the cis flagellum is consistently phase-lagged relative to, whilst remaining robustly phase-locked with, the trans flagellum. Transient loss of synchrony, or phase-slippage, may be triggered stochastically, in which the trans flagellum transitions to a second mode of beating with attenuated beat-envelope and increased frequency. Further, exploiting this alga's ability for flagellar regeneration, we mechanically induced removal of one or the other flagellum of the same cell to reveal a striking disparity between the beating of the cis vs trans flagellum, in isolation. This raises further questions regarding the synchronization mechanism of Chlamydomonas.

description: Nonequilibrium dynamics and effective thermalization are studied in a resonant tunneling scenario via multilevel Landau-Zener crossings. Our realistic many-body system, composed of two energy bands, naturally allows a separation of degrees of freedom. This gives access to an effective temperature and single- and two-body observables to characterize the delocalization of eigenstates and the nonequilibrium dynamics of our paradigmatic complex quantum system.

description: We present Rossiter-McLaughlin observations of WASP-13b and WASP-32b and determine the sky-projected angle between the normal of the planetary orbit and the stellar rotation axis ($λ$). WASP-13b and WASP-32b both have prograde orbits and are consistent with alignment with measured sky-projected angles of $λ={8^{\circ}}^{+13}_{-12}$ and $λ={-2^{\circ}}^{+17}_{-19}$, respectively. Both WASP-13 and WASP-32 have $T_{\mathrm{eff}}<6250$K and therefore these systems support the general trend that aligned planetary systems are preferentially found orbiting cool host stars. A Lomb-Scargle periodogram analysis was carried out on archival SuperWASP data for both systems. A statistically significant stellar rotation period detection (above 99.9\% confidence) was identified for the WASP-32 system with $P_{\mathrm{rot}}=11.6 \pm 1.0 $ days. This rotation period is in agreement with the predicted stellar rotation period calculated from the stellar radius, $R_{\star}$, and $v \sin i$ if a stellar inclination of $i_{\star}=90^{\circ}$ is assumed. With the determined rotation period, the true 3D angle between the stellar rotation axis and the planetary orbit, $ψ$, was found to be $ψ=11^{\circ} \pm 14$. We conclude with a discussion on the alignment of systems around cool host stars with $T_{\mathrm{eff}}<6150$K by calculating the tidal dissipation timescale. We find that systems with short tidal dissipation timescales are preferentially aligned and systems with long tidal dissipation timescales have a broad range of obliquities.
