description: Subterranean ant communities are vastly understudied relative to aboveground ant communities. The thief ants of the genus Solenopsis are a globally abundant and widespread group that is a conspicuous and important part of the below ground ant community. Thief ant ecology, including their distribution and diversity at local scales, has also rarely been documented. In this study, we sampled the subterranean ant community of central Florida, a region with conspicuously high subterranean thief ant abundance. We used a stratified-random sampling protocol and collected soil environmental variables at each sampling plot to model subterranean ant diversity in relation to abiotic conditions in the soil envi ronment. Furthermore, we utilized non-parametric ordination methods and permutation-based analyses of variance to visualize and quantify associations of species based on habitats and soil strata. Our study yielded 15 species from six genera of which five were thief ant species. These five Solenopsis species represented 64% of all ant individuals found. We also identified distinct differences in species composition between two habitat types (pine flatwoods and high pine sandhills) and significant associations of soil abiotic conditions with the diversity of the subterranean community. This study finds that thief ants dominate belowground and respond predictably to soil habitat conditions. Biotic effects among ant species may be important given their purported lestobiotic behaviors.

description: Leafcutter ants are indigenous to Central and South America and the southern Us and are noticeable for their active herbivorous behaviours, collecting mostly fresh plant parts to manure underground gardens of their Leucoagaricus gongylophorus fungal cultivars. These gardens contain a single clone of the cultivar but are also susceptible to path ogens, most notably the specialised mycopathogen Escovopsis. Pathogen pressure led to the evolution of intensive grooming behaviours assisted by antimicrobials produced in endocrine glands and by domesticated antibiotic-producing actinobacteria grown on the integument of workers. The most notable of these are Pseudonocardia species that are abundant in Acromyrmex but have been lost in Atta leafcutter ants. The leafcutter ant symbiosis represents a fascinating example of chemical warfare of which the details are becoming increasingly known. Here, we review recent progress in understanding the complex interactions that take place between the mutualistic and parasitic symbionts, particu larly between the ants, their mutualistic fungal cultivars and cuticular actinobacteria, and their Escovopsis parasites.

description: The absence of cold moving parts in pulse tube cryocoolers has allowed it to has advantages of low vibration, high reliability, and low cost, which can meet requirements of many high-temperature superconducting applications. However, Stirling type pulse tube cryocoolers working around 20 K are still not commerally aviable due to low efficiency and low power density. With Comprehensive consideration of higher specific power of whole system and performance in relative lower working temperature of 20K, this paper proposes a thermally coupled two stage co-axial pulse tube cryocooler to pursue several watts cooling power around 20K.At the first stage, an ultrahigh frequency operation of 100 Hz is utilized to precoo the second stage for seeking a higher power density. At the second stage, a relative lower frequency of around 30Hz is used for improving system efficiency. Firstly, a quasi-one-dimensional numeric model based on the thermoacoustic theory is used to optimize the operating and structure parameters and some simulation results are briefly introduced. The influences of different phase shifters such as doule-inlet and room temperature displacers are also also investigated numerically. Then, in the experiments, typically a lowest no-load temperature of 13 K has been obtained and the cooling power at 20K was 2 W with an input electric power of 500 W, which mean an efficiency of 5.6% of Carnot. The influences of different operating and structure parameters such as frequency, mean pressure and precooling temperature were also investigated numerically and experimentally.

description: Einstein, when he began working on the general theory of relativity, believed that energy of any kind is the source of the gravitational field. Therefore, the energy of gravity, like any energy, must be the source of the field. It was previously discovered that the energy-momentum tensor of the gravitational field is already contained in the Ricci tensor. This hypothesis is used to construct a new equation of the gravitational field.

description: The compact and high efficiency coolers working in the liquid nitrogen temperature region play an important role in HTS Applications. Stirling type pulse tube cooler servers as a promising candidate for cooling HTS devices for its advantages such as low vibration, high reliability and low cost due to absence of the moving parts in the cold head compared with traditional coolers. However, phase shift mechanisms used in a conventional pulse tube cryocooler need to dissipate expansion power at the ambient end of the pulse tube, which leads to a lower thermodynamic efficiency than that of a Stirling cryocooler. In order to improve the efficiency and obtain a reliable cryocooler system, this article presents a pulse tube cryocooler which uses room temperature displacers as the phase shifter, which aims at providing more than 10 W cooling power at 77 K. The cryocooler with a model number of TC4189 consists of linear compressor, coaxial pulse tube and two dual-opposed ambient displacers. High pressure ratio and high frequency operation are used to increase the power density. The whole system has a total mass of 4.3 kg. At an optimum working point, a lowest no-load temperature of 44 K has been obtained and the cooling power at 80K reaches 15 W with an input electric power of 240 W, which means an efficiency of 17.1% of Carnot. The influence of displacers operating and structural parameters were investigated through simulations and experiments.

description: In order to develop small-scale nuclear magnetic resonance devices, the authors have been developing uniform magnetic fields in the space between the face-to-face settled magnetic poles which contain HTS bulk magnets. Since the NMR magnets in general require highly uniform field, it was expected to be difficult to form such homogeneous magnetic-field distribution with use of HTS bulk magnet, because the bulk magnets is characterized by its inhomogeneous magnetic field showing steep gradient. The authors modified the shape of the field distribution from convex to concave by attaching an iron plate on the pole surface. Then, the magnets were then settled face-to-face with various gaps, and the magnetic-field uniformity was estimated in the space. In order to detect the NMR signals, the field uniformity less than 1,500 ppm should be required after the former results on the hollow-type magnets. When we combined the concave and convex field distributions to compensate the uneven field distributions, the best uniformity reached 358 ppm in the 30 mm gaps, which exceeded the target value. In addition, we numerically simulated the feasible performance in this configuration, which resulted in obtaining the best uniformity of 30 ppm at 1.1 T at 7 mm distant from the pole surface in the gap of 30 mm. This result suggested that the concave and convex magnetic field distributions compensate the field uniformity with each other with keeping the magnetic field strength in the gap.

description: Temperature rise is expected to impact the interactions between phytophagous species and host plant systems, particularly aphids. As poikilothermic organisms, aphids' development is influenced by temperature, leading to increased development, reproduction, and survival. As a model organism for studying climate change effects, aphids can be affected by oxidative stress, which can impair mitochondrial function. Plants can manufacture reactive oxygen species (ROS) as a defense against phytophagous organisms. Enzymatic systems regulate ROS production and removal, with antioxidant enzymes like superoxide dismutase and catalase protecting aerobic organisms against OS. Enzymes like glutathione S-transferase and β-glucosidase are crucial for defense in plants.

description: Procedural material models have been gaining traction in many applications thanks to their flexibility, compactness, and easy editability. We explore the inverse rendering problem of procedural material parameter estimation from photographs, presenting a unified view of the problem in a Bayesian framework. In addition to computing point estimates of the parameters by optimization, our framework uses a Markov Chain Monte Carlo approach to sample the space of plausible material parameters, providing a collection of plausible matches that a user can choose from, and efficiently handling both discrete and continuous model parameters. To demonstrate the effectiveness of our framework, we fit procedural models of a range of materials---wall plaster, leather, wood, anisotropic brushed metals and layered metallic paints---to both synthetic and real target images.

description: Ziel: In Rahmen dieser Diplomarbeit wurden anhand einer experimentellen Studienreihe 16 verschiedene Materialien mit der Multidetektorcomputertomografie (MDCT) unter Benützung eines standardisierten Herz- CT- Protokolls gescannt und mit Hilfe unterschiedlicher Segmentationsmethoden volumetriert, um eine standardisierte Methode zur Soft- Plaque- Quantifizierung aus CT- Daten abzuleiten. Material: Das finale Softplaquephantom bestand aus einem Kunststoffschlauch (Gefäßimitat) und vier Seifenstücken bzw. vier Seifen/Fettkomplexen (Softplaqueimitate), das mittels MDCT untersucht wurde. Die gewonnenen Daten wurden mit drei Segmentationsmethoden und drei verschiedenen Schwellwertintervallen segmentiert und volumetriert. Die Materialien wurden zusätzlich mit einem Oberflächenscanner gescannt, deren ausgewertete Volumina als Referenz und Golden Standard dieser Arbeit dienten und mit den segmentierten CT- Daten verglichen wurden. Ergebnisse: Es zeigte sich, dass die Wahl der Schwellwertsetzung eine entscheidende Auswirkung auf die Segmentationen der Softplaqueimitate hatte. Eine Übereinstimmung der segmentierten Volumina mit den Referenz- Volumina, konnte nur mit Hilfe einer HMH- Schwellwertsetzung erzielt werden. Die Ergebnisse der segmentierten Seifen/Fettkomplexe zeigten etwas größere Volumina. Des weiteren wiesen die Volumina der CT- Daten eine Überbewertung um mindestens 48 % auf, wurden die Segmentationen bei voller Grauwertdynamik (= -1024 HU bis maximale Grauwerte) durchgeführt. Schlussfolgerung: Trotz der hohen Auflösung des MDCT- 64 und der Wahl geeigneter Schwellwertintervalle wurde bei den Seifen/Fettkomplexen eine Tendenz der Plaque- Überschätzung ermittelt. Diese leichte Überbewertung könnte einerseits auf den Partialvolumeneffekt, andererseits auf die Grauwertüberschneidung der unterschiedlichen Gewebearten zurückgeführt werden. Als effektiv hat sich Seife als Soft- Plaque- Phantom und die Einführung des Oberflächenscanners als Referenzmessung erwiesen.

description: The problem of building a coherent and non-monotonous conversational agent with proper discourse and coverage is still an area of open research. Current architectures only take care of semantic and contextual information for a given query and fail to completely account for syntactic and external knowledge which are crucial for generating responses in a chit-chat system. To overcome this problem, we propose an end to end multi-stream deep learning architecture which learns unified embeddings for query-response pairs by leveraging contextual information from memory networks and syntactic information by incorporating Graph Convolution Networks (GCN) over their dependency parse. A stream of this network also utilizes transfer learning by pre-training a bidirectional transformer to extract semantic representation for each input sentence and incorporates external knowledge through the the neighborhood of the entities from a Knowledge Base (KB). We benchmark these embeddings on next sentence prediction task and significantly improve upon the existing techniques. Furthermore, we use AMUSED to represent query and responses along with its context to develop a retrieval based conversational agent which has been validated by expert linguists to have comprehensive engagement with humans.

description: We present a connection between minimal surfaces of index one and General Relativity. First, we show that for a certain class of (electro)static systems, each of its unstable horizons is the solution of a one-parameter min-max problem for the area functional, in particular it has index one. We also obtain an inequality relating the area and the charge of a minimal surface of index one in a Cauchy data satisfying the Dominant Energy Condition for non-electromagnetic matter fields. Moreover, we explore a global version of this inequality, and the rigidity in the case of the equality, using a result proved by Marques and Neves.
description: Final version. Accepted for publication in Journal of Differential Geometry. We extended one of the main results to the case where the boundary has degenerate minimal surfaces (Theorem C). Also, we now only use the Simon-Smith version of min-max theory. Finnaly, we improved the presentation of the paper, following the suggestions of the referee

description: We propose an approach to realize a hybrid quantum system composed of a diamond nitrogen-vacancy (NV) center spin coupled to a magnon mode of the low-damping, low-moment organic ferrimagnet vanadium tetracyanoethylene. We derive an analytical expression for the spin-magnon cooperativity as a function of NV position under a micron-scale perpendicularly magnetized disk, and show that, surprisingly, the cooperativity will be higher using this magnetic material than in more conventional materials with larger magnetic moments, due to in part to the reduced demagnetization field. For reasonable experimental parameters, we predict that the spin-magnon-mode coupling strength is $g\sim 10$ kHz. For isotopically pure $^{12}$C diamond we predict strong coupling of an NV spin to the unoccupied magnon mode, with cooperativity $\mathcal C=6$ for a wide range of NV spin locations within the diamond, well within the spatial precision of NV center implantation. Thus our proposal describes a practical pathway for single-spin-state-to-single-magnon-occupancy transduction and for entangling NV centers over micron length scales.

Development of High-capacity Single-stage GM Cryocoolers at SHI

Publisher: name: Karlsruhe

description: Applications including HTS superconducting motor, power transmission line and power generator are usually considered to consume 102 W to 104 W cooling power. Most of those applications are currently using direct liquid nitrogen cooling or Turbo-Brayton cryocoolers. Though having the potential to significantly reduce the cost and space requirement, current commercial GM cryocoolers lack the suitable cooling power which is crucial in HTS applications. Since 2013, Sumitomo Heavy Industries, Ltd. (SHI) has been developing high capacity single stage GM cryocoolers for HTS applications around 80 K. With a conventional scotch-yoke-driven single-displacer GM cryocooler, a cooling capacity of 650 W was achieved with an input power of about 13 kW. To further improve the efficiency, a novel concept, called dual-displacer GM cryocooler has been developed since 2015. In a dual-displacer GM cryocooler, displacers are connected to both ends of the Scotch yoke. Two expansion spaces are constructed by the displacers and cylinders. Helium gas is supplied to and discharged from the upper and the lower expansion spaces with a phase shift of about 180°. In principle, the pressure oscillation amplitude at the compressor side is reduced and thus the overall efficiency of the cryocooler is improved. With a dual-displacer concept, a cooling capacity of 725 W at 80 K was achieved with an input power of 13.8 kW. In a Scotch yoke type GM cryocooler, the driving mechanism becomes heavier and more complicated as the required cooling capacity increases. Recently, SHI has been developing pneumatic GM cryocoolers. As preliminary results, a cooling capacity of 700 W at 80 K was achieved with an input power of 18.0 kW. A summary of the development status of such cryocoolers will be reported in this presentation.

description: This book is devoted to the problem of sequential probability forecasting, that is, predicting the probabilities of the next outcome of a growing sequence of observations given the past. This problem is considered in a very general setting that unifies commonly used probabilistic and non-probabilistic settings, trying to make as few as possible assumptions on the mechanism generating the observations. A common form that arises in various formulations of this problem is that of mixture predictors, which are formed as a combination of a finite or infinite set of other predictors attempting to combine their predictive powers. The main subject of this book are such mixture predictors, and the main results demonstrate the universality of this method in a very general probabilistic setting, but also show some of its limitations. While the problems considered are motivated by practical applications, involving, for example, financial, biological or behavioural data, this motivation is left implicit and all the results exposed are theoretical.
 The book targets graduate students and researchers interested in the problem of sequential prediction, and, more generally, in theoretical analysis of problems in machine learning and non-parametric statistics, as well as mathematical and philosophical foundations of these fields.
 The material in this volume is presented in a way that presumes familiarity with basic concepts of probability and statistics, up to and including probability distributions over spaces of infinite sequences. Familiarity with the literature on learning or stochastic processes is not required.

description: Despite being the dominant force of nature on large scales, gravity remains relatively elusive to experimental measurement. Many questions remain, such as its behavior at small scales or its role in phenomena ascribed to dark matter and dark energy. Atom interferometers are powerful tools for probing Earth's gravity, the gravitational constant, dark energy theories and general relativity. However, they typically use atoms in free fall, which limits the measurement time to only a few seconds, and to even briefer intervals when measuring the interaction of the atoms with a stationary source mass. Recently, interferometers with atoms suspended for as long as 70 seconds in an optical lattice have been demonstrated. To keep the atoms from falling, however, the optical lattice must apply forces that are billion-fold as strong as the putative signals, so even tiny imperfections reduce sensitivity and generate complex systematic effects. As a result, lattice interferometers have yet to demonstrate precision and accuracy on par with their free fall counterparts and have yet to be used for precision measurement. Here, we optimize the sensitivity of a lattice interferometer and use a system of signal inversions and switches to suppress and quantify systematic effects. This enables us to measure the attraction of a miniature source mass, ruling out the existence of screened dark energy theories over their natural parameter space. More importantly, the combined accuracy of $6.2~\rm{nm/s}^2$ is four times as good as the best similar measurements with freely falling atoms, demonstrating the advantages of lattice interferometry in fundamental physics measurements. Further upgrades may enable measuring forces at sub-millimeter ranges, the gravitational Aharonov-Bohm effect and the gravitational constant, compact gravimetry, and testing whether the gravitational field itself has quantum properties.

title: Die Virgen de Guadalupe und la Malinche
Creators: name: Mieling, Caroline

description: Diese Arbeit besteht aus zwei sich ergänzenden Teilen. Einem praktischen Teil, dem 35 minütigen ethnologischen Dokumentarfilm, Ruega por nosotros-Bitt für uns 2009, der während meines Forschungsjahres 2008 in Guadalajara, Mexiko, entstanden ist, und dem hier vorliegenden schriftlichen Teil.Ich stelle zwei weibliche mexikanische Mythenfiguren vor und gehe der Frage nach, welche Frauenrollen sie innerhalb der mexikanischen Gesellschaft vorgeben und ob und wie sie zur Legitimierung des Machismo in Mexiko beitragen. Zum einen spreche ich vom Mythos der Virgen de Guadalupe, der Mestizen-Madonna und Landespatronin Mexikos. Die Jungfrau ist für den mexikanischen Mann das weiblich Perfekte,Fehlerlose und Reine. Für die Frau stellt sie ein nachzuahmendes Modell dar, nachgiebig, ausgleichend und mit mütterlichen Instinktmerkmalen, die gleichzeitig ihre Sexualität negiert. Gotteshingabe, Reinheit und Mutterschaft sind die Basis für das Ideal des Marianismo - Konzepts von Evelyn Stevens, das dem Machismo gegenüber steht. Über ihre Rolle als Mutter und nachgiebige, gottesfürchtige Ehefrau wird die mexikanische Frau in der mexikanischen Gesellschaft meist definiert und kann darüber sowohl an Wert gewinnen als auch an Wert verlieren. Zum anderen geht es um die Mythe der Malinche, der indigenen Frau, die zur Zeit der Conquista, den Spaniern durch ihr sprachliches und strategisches Können bei der Eroberung des Landes geholfen haben soll. Seit den 1970er Jahren, als Schriftsteller, Dichter und Künstler auf der Suche nach der mexikanischen Identität waren, wurde sie bekannt als Verräterin am mexikanischen Volk und zur mythischen Urmutter der Mestizaje.

description: We consider vanishing properties of exponential sums of the Liouville function $λ$ of the form $$ \lim_{H\to\infty}\limsup_{X\to\infty}\frac{1}{\log X}\sum_{m\leq X}\frac{1}{m}\sup_{α\in C}\bigg|\frac{1}{H}\sum_{h\leq H}λ(m+h)e^{2πihα}\bigg|=0, $$ where $C\subset\mathbb{T}$. The case $C=\mathbb{T}$ corresponds to the local $1$-Fourier uniformity conjecture of Tao, a central open problem in the study of multiplicative functions with far-reaching number-theoretic applications. We show that the above holds for any closed set $C\subset\mathbb{T}$ of zero Lebesgue measure. Moreover, we prove that extending this to any set $C$ with non-empty interior is equivalent to the $C=\mathbb{T}$ case, which shows that our results are essentially optimal without resolving the full conjecture. We also consider higher-order variants. We prove that if the linear phase $e^{2πihα}$ is replaced by a polynomial phase $e^{2πih^tα}$ for $t\geq 2$ then the statement remains true for any set $C$ of upper box-counting dimension $<1/t$. The statement also remains true if the supremum over linear phases is replaced with a supremum over all nilsequences coming form a compact countable ergodic subsets of any $t$-step nilpotent Lie group. Furthermore, we discuss the unweighted version of the local $1$-Fourier uniformity problem, showing its validity for a class of ``rigid'' sets (of full Hausdorff dimension) and proving a density result for all closed subsets of zero Lebesgue measure.

Heat transfer in HTS transformer and current limiter windings

description: Design of cryogenic systems for HTS transformers and fault current limiters (FCL) must provide for fault conditions as well as normal operation. In the course of a fault the HTS windings may be heated rapidly to a temperature of 300 K or higher. The ability of the device to return to normal operation after a fault current depends critically on the efficiency of heat transfer from the hot windings to the cooling system. The engineering of the interface of the winding with the cryogen, generally liquid nitrogen in the case of HTS transformers and FCL, can properly be considered a crucial component of cooling system design. We report measurements of heat transfer from short metal and superconductor tape samples immersed in liquid nitrogen in conditions which approximate those in an HTS transformer winding. Samples were subjected to current pulses of several hundred A/mm2 for time intervals up to 2 seconds. The average sample temperature was estimated from the resistance. The current density during cool down was varied over the range corresponding to HTS transformer operation. Heat transfer was measured on samples with UV-cured polymer coatings as well as on bare samples. Somewhat paradoxically, by thermally insulating the metal surface from the liquid nitrogen the coating can drastically improve heat transfer. It does this by avoiding film boiling - the formation of a gas sheath on the surface - and extending the range of efficient cooling by nucleate boiling where the liquid is able to continuously wet the hot surface. 
We find that heat transfer during conductor cool down:
- Is highest in subcooled operation e.g. at 65 K at atmospheric pressure compared to operation at the boiling point e.g. 77.3 K at atmospheric pressure
- Is significantly increased by a thermally insulating coating of optimised thickness applied to the conductor compared to bare conductor, and reduced by wrapped-paper electrical insulation
Temporal variation in social structure and worker reproduction in the temporary social parasite Lasius fuliginosus (Hymenoptera: Formicidae)

description: Ant societies exhibit striking diversity in their social systems, including variation in the number of queens and mating partners. Knowledge on the number of breeders in a colony is crucial for a better understanding of the evolution of social insect life history traits such as reproductive skew or worker reproduction. Little is known about the breeding system of the formicine ant Lasius fuliginosus (latreille, 1798), even though it is widely distributed in the Palearctic and able to compete ecologically with dominant genera like Formica. Moreover, L. fuliginosus has a particularly interesting life history in that it is a temporary social parasite of several Lasius species, which themselves are tem porary social parasites. We determined the number of (reproductive) queens and mating partners of L. fuliginosus colonies and queens, respectively, from a population in Münster, Germany. Workers from 33 colonies and males from 12 of these colonies were genotyped for four polymorphic microsatellite markers. Our results show that 29 of these colonies were monogynous and monandrous and that two colonies were monogynous and polyandrous. Workers of the remaining two colonies were derived from multiple queens, possibly due to adoption of unrelated queens after the original queen’s death. Furthermore, genotyping of male offspring provided evidence for worker reproduction in three colonies, potentially also in response to queen orphanage in two of these. We estimated the mutation rate at one microsatellite locus in L. fuliginosus to be 1.46 × 10-3 mutations per generation, which is similar to what has been observed in Apis mellifera linnaeus, 1758 and Drosophila melanogaster meiGen, 1830. To our knowledge, this is the first study to provide molecular insights into the breeding system of L. fuliginosus, which appears to be characterized by facultative polyandry and monogyny. In addition, L. fuliginosus now represents the second species in the genus Lasius for which worker reproduction has been documented.

description: We give a mathematical definition of spaces of irregular vacua/covacua in genus zero, for any simple Lie algebra, working at generic noncritical level. This uses coinvariants of affine-Lie-algebra modules whose parameters match up with those of moduli spaces of irregular-singular meromorphic connections: the de Rham spaces. The Segal--Sugawara representation of the Virasoro algebra is used to show that the spaces of irregular conformal blocks assemble into a flat vector bundle over the space of somonodromy times à la Klarès, and we provide a universal version of the resulting flat connection generalising the irregular KZ connection of Reshetikhin and the dynamical KZ connection of Felder--Markov--Tarasov--Varchenko.

Even though nutria has been known as invasive alien species especially around southern Korean peninsula, Jeju had remained nutria free. The feral nutria occurrence on Jeju is a major concern. Four individuals occurred on Southern wetland in 2011. Because there are several Nutria farms on Jeju, it will be necessary to ensure accidental or intentional releases do not occur.
 According to national list of Korean mammals (NIBR, 2012), 71 species of terrestrial mammals are listed as present on the Korean peninsula, and 28 species occur on Jeju Island (Table 3). With 5 species of invasive mammals (Sus scrofa, Cervus nippon, Sciurus vulgaris, Tamias sibiricus and Myocastor coypus), Jeju has 1 endemic species (Apodemus chejuensis) and 3 subspecies (Sorex caecutiens hallamontanus, Mustela sibirica quelpartis and Micromys minutes hertigi). Also, the subspecific level of white-toothed shrew (Crocidura sp) on Jeju is not clear. Compared to the Korean peninsula, which has 1 endemic mammal (NIBR, 2011), the number of endemic mammals on Jeju is quite large. Conservation of this island’s endemism is an important priority (Van Dyke, 2008).

description: Connecting double quantum dots via a semiconductor-superconductor hybrid segment offers a platform for creating a two-site Kitaev chain that hosts a pair of "poor man's Majoranas" at a finely tuned sweet spot. However, the effective couplings, which are mediated by Andreev bound states in the hybrid, are generally weak in the tunneling regime. As a consequence, the excitation gap is limited in size, presenting a formidable challenge for using this platform to demonstrate non-Abelian statistics of Majoranas and realizing error-resilient topological quantum computing. In this work, we systematically study the effects of increasing the coupling between the dot and the hybrid segment. In particular, the proximity effect transforms the dot orbitals into Yu-Shiba-Rusinov states, forming a new spinless fermion basis for a Kitaev chain, and we derive a theory for their effective coupling. As the coupling strength between the dots and the hybrid segment increases, we find a significant enhancement of the excitation gap and reduced sensitivity to local perturbations. Although the hybridization of the Majorana wave function with the central Andreev bound states increases strongly with increasing coupling, the overlap of Majorana modes on the outer dots remains small, which is a prerequisite for potential qubit experiments. We discuss how the strong-coupling regime shows in experimentally accessible quantities, such as the local and non-local conductance, and provide a protocol for tuning a double-dot system into a sweet spot with a large excitation gap.

 Sika deer populations in Korea have been regarded as 2 subspecies, C. n. hortulorum and C. n. mantchuricus. The Jeju population was considered as C. n. mantcuricus (Won, 1967).
 Sika deer on Jeju used to be abundant, but became extinct around 1915 (Mori, 1928). In 1992 and 1993, 12 Taiwanese sika deer (C. n. taioanus) were released for restoration in private without scientific planning (Oh et al., 2007). These individuals were present until 2004, but it is unknown if they still persist. The situation is complicated as several private deer farms operate on Jeju.

description: Contingent workers are those individuals without any expectation of long-term or continuous employment within an organization. Within the field of higher education, contingent workers include part-time adjuncts and full-time nontenure-track faculty members, The use of contingent faculty has increased over the years, particularly within the field of higher education. According to U.S. Bureau of Labor Statistics analyst Steven Hipple, 25 percent of the contingent workers holding advanced degrees in 1999 were college or university instructors. The 2009 Almanac of the Chronicle of Higher Education reports that in 2007, 51 percent of faculty members were full-time compared with 49 percent categorized as part-time.
