description: We develop a new density-based clustering algorithm named CRAD which is based on a new neighbor searching function with a robust data depth as the dissimilarity measure. Our experiments prove that the new CRAD is highly competitive at detecting clusters with varying densities, compared with the existing algorithms such as DBSCAN, OPTICS and DBCA. Furthermore, a new effective parameter selection procedure is developed to select the optimal underlying parameter in the real-world clustering, when the ground truth is unknown. Lastly, we suggest a new clustering framework that extends CRAD from spatial data clustering to time series clustering without a-priori knowledge of the true number of clusters. The performance of CRAD is evaluated through extensive experimental studies.

description: Finite topological spaces became much more essential in topology, with the development of computer science. The task of this paper is to study and investigate some properties of such spaces with the existence of an ordered relation between their minimal neighborhoods. We introduce notations and elementary facts known as Alexandroff space. The family of minimal neighborhoods forms a unique minimal base. We consider T_0 spaces. We give a link between finite $T_0$ spaces and the related partial order. Finally, we study some properties of multifunctions and their relationships with connected ordered topological spaces.

description: Even before other socialist countries in Central and Eastern Europe (CEE) and the former Soviet Union (FSU) had done so, China and Vietnam embarked on a decollectivization process, where collective farming was completely abolished and family farming re-emerged. When the CEE and FSU countries started farm restructuring during the early 1990s, the East Asian way seemed to be the model. Some countries followed suit, while others provided the legal basis for a competitive environment between various types of farm organizations. One vital feature, however, is the fact that agricultural service cooperatives, contrary to China and Vietnam, only play a marginal role in these countries. Though the farmers from China and Vietnam and from the CEE and FSU countries had equally bitter memories of their respective collective periods, we argue that additional stakeholders were decisive in cooperative development. This might be a vital factor for why agricultural production prospered so quickly.

 Alloperla alexanderi Nelson and Hanson, 1968
 Alloperla mediata Zwick, Levanidova, & Zhiltzova, 1971
 TYPE LOCALITY: Siberia: Vladivostok.
 DIAGNOSIS: The pronotum of A. mediata has a characteristic dark medial stripe (Fig. 100), in addition to the abdominal stripe typical in most Mongolian Chloroperlidae. The anteriorly directed epiproct is short and pointed, composed of two portions, nearly subequal in width, which are separated by a pronounced constriction. This is in contrast to A. rostellata, in which the anterior portion of the epiproct is much wider than the base (Fig. 105). Numerous lateral and ventral spines on the epiproct are visible from the dorsal view, similar to A. rostellata but unlike in A. joosti where they are only visible laterally. From the lateral view, the epiproct is uniform in width, whereas in A. rostellata it is thinner near the tip. The female subgenital plate (Fig. 102) is a long, narrow triangle with a rectangular, parallel-sided base, extending nearly the entire length of sternum 9. A. rostellata has a similar shaped plate (Fig. 106), but it only extends slightly over sternum 8. The nymphs of Mongolian Alloperla are indistinguishable at the species level.
 DISTRIBUTION—Global: East Palearctic— Regional: AOB^— Aimag: BU^, KhG^.
 DISCUSSION: This species is a new record for Mongolia and specimens documented by our study were included in a preliminary checklist of Mongolian stoneflies (Surenkhorloo 2009). Predictive modeling suggests that this species will also be found in eastern mountains of Mongolia (Fig. 103).

description: The paper describes a MAS (multi-agent system) simulation approach for controlling PM10 (Particulate Matter) crisis peaks. A dispersion model is used with an Artificial Neural Network (ANN) to predict the PM10 concentration level. The dispersion and ANN models are integrated into a MAS system. PM10 source controllers are modelled as software agents. The MAS is composed of agents that cooperate with each other for reducing their emissions and control the air pollution peaks. Different control strategies are simulated and compared using data from Annaba (North-East Algeria). The simulator helps to compare and assess the efficiency of policies to control peaks in PM10.

description: This study presents the design of a multimodal ubiquitous learning application (MULA) with different augmenting effects for enhancing English as a Foreign Language (EFL) academic writing instruction. In a pilot project, 17 undergraduates engaged in ubiquitous learning and writing at a green building and provided survey responses and interview feedback about their ubiquitous writing experience. The survey results were categorized into perceptions about (a) the ubiquitous learning mode, (b) effective writing facilitation, (c) motivation, self-efficacy, and attitude, (d) self-regulation, and (e) system usability. Interview results further illustrated how using MULA led to positive and negative experiences during ubiquitous writing. A final synthesis on the findings led to the identification of seven affordances that made MULA a potential tool for enhancing writing instruction in EFL settings. The seven affordances were considered effective design elements for multimodal context-aware ubiquitous learning that served the purpose of enriching English academic writing instruction. Implications about creating multimodal ubiquitous learning applications in higher education are also provided.
Critical universality and hyperscaling revisited for Ising models of general spin using extended high-temperature series

description: We have extended through beta^{23} the high-temperature expansion of the second field derivative of the susceptibility for Ising models of general spin, with nearest-neighbor interactions, on the simple cubic and the body-centered cubic lattices. Moreover the expansions for the nearest-neighbor correlation function, the susceptibility and the second correlation moment have been extended up to beta^{25}. Taking advantage of these new data, we can improve the accuracy of direct estimates of critical exponents and of hyper-universal combinations of critical amplitudes such as the renormalized four-point coupling g_r or the quantity usually denoted by R^{+}_{xi}. We have used a variety of series extrapolation procedures and, in some of the analyses, we have assumed that the leading correction-to-scaling exponent theta is universal and roughly known. We have also verified, to high precision, the validity of the hyperscaling relation and of the universality property both with regard to the lattice structure and to the value of the spin.

description: Accession to the European Union as well as the ongoing process of liberalization of global agricultural trade changed the conditions for agri-food trade between Poland and NAFTA countries. The study is an attempt to defi ne the signifi cance of NAFTA countries in the Polish agri-food trade, to assess the competitive position of selected Polish agri-food products on this market in years 2004–2012 and to predict its level for the year 2020, assuming two simulation scenarios: the lack of liberalization (I) and liberalization of world agricultural trade (II). A deliberately selected set of ex post indicators of competitive position as well as agricultural sector equilibrium model CAPRI (Common Agricultural Policy Regionalised Impact) were used in the paper. The analysis showed that among non-EU countries this trade bloc is one of the most important trade partners for Poland. On this foreign market mainly Polish animal products and fruits and vegetables were competitive. The results of model simulations conducted for different groups of agri-food products showed that by 2020 a favourable competitive position on the NAFTA market might be expected in meat and meat products as well as in milk and dairy products.

description: Latohexapus Huang, Hsueh & Ng, 2002
 Latohexapus Huang, Hsueh & Ng, 2002: 652.
 Emended diagnosis. Carapace much broader than long; regions distinct, separated by deep groove, strongly granulated. Eye movable; anterolateral margin arcuate. Pterygostomial region with row of striae, granular; ischium of third maxillipeds expanded distally, longer than merus; exopod with well developed flagellum. Chelipeds asymmetrical, with prominent teeth at base of fingers. Surfaces of P2–P4 granular, dactylus upcurved. Male thoracic sternum very broad; surface prominently granular; sternites 1 and 2 fused, strongly bent backward, separated from sternite 3 by distinct transverse ridge; deep transverse groove separating thoracic sternites 3 and 4; sternoabdominal cavity extending from edge of abdominal cavity to base of chelipeds; sternite 8 exposed. Male abdomen with somites 3–5 fused; somite 6 appearing hexagonal, with median part prominently expanded into triangular projection; telson subpentagonal. G1 very slender, directed anterolaterally, distal quarter not concealed under abdomen.
 Species included. Latohexapus granosus Huang, Hsueh & Ng, 2002 (type species by original designation).
 Remarks. So far this is the only genus in the family that has the carapace much broader than long and with the regions distinctly demarcated. As discussed by Huang et al. (2002), the extension of the male thoracic sternal groove is comparable to the condition in Lambdophallus but several differences such as movable eyes (versus immovable eyes in Lambdophallus), the shapes of the third maxillipeds with the ischium expanded distally in Latohexapus (Huang et al., 2002: fig. 4D) (versus slightly convex in Lambdophallus, Manning & Holthuis, 1981: fig. 34b), and the male abdominal somite 6 appearing hexagonal (Huang et al., 2002: fig. 4G) (versus almost squarish in Lambdophallus, Manning & Holthuis, 1981: fig. 34C) easily distinguishes the two genera.

description: We present the first analytical study of stability loss and evolution of domain structure in inhomogeneous ferroelectric samples for exactly solvable model. The model assumes a short-circuited capacitor with two regions with slightly different critical temperatures Tc1 > Tc2, where Tc1-Tc2 << Tc1, Tc2. Even a tiny inhomogeneity like 10-5 K may result in splitting the system into domains below the phase transition temperature. At T < Tc2 the domain width $a$ is proportional to (Tc1 - T)/(Tc1 - Tc2) and quickly increases with lowering temperature. The minute inhomogeneities in Tc may result from structural (growth) inhomogeneities which are always present in real samples and a similar role can be played by inevitable temperature gradients.

description: As social media have become an integral part of many people’s everyday life, there has been an increasing interest in exploring how the content shared through those online platforms comes to contribute to the collaborative creation of places in physical space. Indeed, the distinction between online and physical spaces and activities is rapidly degrading. However, exploring those digital geographies is a complex task due to the quantity and variety of data. In this paper, we introduce a semi-supervised, deep neural network approach to classify geolocated social media posts based on their text content, media content, and geographic location, using a limited set of arbitrary categories. Our approach combines a stacked multi-modal autoencoder neural network to create joint representations of text and images, and graph convolution neural network for semi-supervised classification. The results presented in this paper show that our approach performs the classification of social media content with higher accuracy than a traditional Support Vector Machine model. Thus, the presented approach has the potential to develop into a powerful tool to complement content analysis in the study of digital geographies.

description: Improving public transport relies on the development of appropriate tools for measuring and monitoring service quality. While there are several studies exploring perceived service quality, these works are mainly based on surveys, which are limited to a pre-de fined period and do not enable to constantly observe and analyze the respond of passengers to different events. As a result, they may miss events affecting service quality in a transport hub. In contrast, social media feeds provide an opportunity to constantly look for events that may affect the service quality. However, in a confi ned geographic area like a transport hub, the sparsity of data considerably reduce the effectiveness of straight-forward event detection methods. In contrastto earlier works and in order to face these challenges, in this paper, we explore the effectiveness of sentiment analysis to detect events impacting perceived service quality in a con fined location. Southern Cross Station, a major transport hub in Melbourne, Australia, is selected as a casestudy. Moreover, a statistical approach to combine and integrate sentiment-based and frequency-basedevent detection is proposed. Main findings con rm the effectiveness of sentiment analysis for detecting events affecting service quality in a transport hub. Additionally, the results prove that the proposed method can improve the sensitivity of event detection for events affectingservice quality.

description: Αντικείμενο της παρούσας διπλωματικής εργασίας είναι να παρουσιάσουμε την σχέση μεταξύ λογιστικής συντηρητικότητας και χρηματοοικονομικής μόχλευσης και πως η λογιστική συντηρητικότητα επηρεάζει την χρηματοοικονομική μόχλευση. Ακόμη θα εξεταστεί η μεταβολή της χρηματοοικονομικής μόχλευσης και πως αυτή επηρεάζεται από την λογιστική συντηρητικότητα. Σύμφωνα με την βιβλιογραφία όσο αυξάνεται η λογιστική συντηρητικότητα αυξάνεται και ο δανεισμός (Garcia Lara et al, 2016; Ahmed et al, 2007; Kang et al., 2015). Θεωρούμε ότι η λογιστική συντηρητικότητα διευκολύνει τις οικονομικές οντότητες να έχουν πιο εύκολα πρόσβαση στο δανεισμό, προστατεύοντας επίσης τους δανειστές (Garcia Lara et al, 2016; Ζhang, 2008; Guay and Verrecchia, 2007; Watts, 2003; Ball and Shivakumar, 2005). Τα αποτελέσματα της οικονομετρικής ανάλυσης αφορούν τις εταιρείες δύο χωρών οι οποίες είναι η Γερμανία και το Ηνωμένο Βασίλειο και καλύπτουν την περίοδο από το 2005 έως το 2019. Οι χώρες αυτές επιδεχθήκαν γιατί παίζουν σημαντικό ρόλο στην παγκόσμια οικονομία συνεπώς είναι δύο ισχυρές χώρες. Για να υπολογίσουμε την λογιστική συντηρητικότητα εφαρμόζουμε δύο διαφορετικούς τρόπους οι οποίοι βασίζονται στην έρευνα των Givoly and Hayan (2000). Σκοπός της εργασίας είναι να φανεί τι επίδραση έχει η λογιστική συντηρητικότητα στην μόχλευση, καθώς και τι επίδραση έχει στη μεταβολή της μόχλευσης. Καταλήξαμε λοιπόν ότι η λογιστική συντηρητικότητα έχει θετική επίδραση στη μόχλευση χρησιμοποιώντας το πρώτο proxy λογιστικής συντηρητικότητας και αρνητική επίδραση όταν χρησιμοποιείται το δεύτερο proxy, αποδεικνύοντας το με τη βοήθεια μεταβλητών ελέγχου. Το δείγμα πρώτα εξετάζεται για την Γερμανία έπειτα για το Ηνωμένο Βασίλειο και στο τέλος εξετάζονται και οι δύο χώρες μαζί.

Isocapnia

description: Isocapnia
 DIAGNOSIS: Adults are dark brown (Fig. 48) often with golden-brown rugosites (mottled patterning) behind the eyes and on the pronotum (Fig. 50). The male epiproct is long and narrow (Fig. 51), especially in comparison to Capnia and Mesocapnia. The epiproct is often characteristically shaped at the apex, although this can only be seen at high magnifications. The male has a ventral vesicle extending from sternum 9 (Fig. 52), which is similar to the vesicle of Eucapnopsis (Fig. 45) but more darkly sclerotized in Isocapnia. The female subgenital plate often has diagnostic sclerotization patterns (Fig. 53, 58). The cerci of the nymph (Fig. 24) have long intrasegmental hairs in addition to shorter apical whorls. Later instar male nymphs have a posterior extension between the cerci encasing the developing epiproct.
 DISTRIBUTION—Global: Holarctic— Regional: AOB, IDB— Aimag: AR, BU^, KhD*, KhG^, SE^, TO^, UB^, ZA.
 DISCUSSION: The Isocapnia of Mongolia seem to be restricted to the Selenge (AOB) drainage (Fig. 49), with only a few specimens occurring in the eastern-most portions of the Internal Drainage basin. However, we suspect that this genus is more widespread due to the new record of I. kudia for Mongolia which demonstrates that members of this genus may be undersampled. Recently, the genus was revised by Zenger and Baumann (2004) and the Palearctic nymphs described and illustrated by Teselenko and Zhiltzova (2003).

 DIAGNOSIS: Suwallia kerzhneri has light yellow body coloration with a darkly rimmed pronotum with a thin medial stripe, dark U-shaped markings on the meso- and metanota, and a dark, longitudinal abdominal stripe that usually extends through tergum 10 (Fig. 122). In general the coloration is similar to S. teleckojensis (Fig. 126), but S. kerzhneri has thinner medial stripes on the pronotum and abdomen (Fig. 122). The medially directed hemitergal processes (Fig. 123) of the male are flattened throughout and pointed at the apex, in contrast to S. teleckojensis which are cylindrical and rounded. The hemitergal processes of S. kerzhneri often appear slightly twisted causing them to be directed more anteriorly. The epiproct knob has long hairs only along the posterior margin (Fig. 123), leaving the central region bare. The female subgential plate is laterally incised at the base with the posterior end forming a broadly rounded process that covers all of sternum 9. The plate is darkly sclerotized on its truncate apex, in contrast to S. teleckojensis which instead has dark basal scelerites (Fig. 128). The nymph is unknown.
 DISTRIBUTION—Global: East Palearctic— Regional: AOB— Aimag: AR, KhG^, SE^, TO, UB*, ZA.
 DISCUSSION: This species was originally described from Mongolia (Zhiltzova & Zwick 1971) and is now known throughout the eastern Palearctic (Levanidova & Zhiltzova 1979). In Mongolia, it is a rare species relative to S. teleckojensis with which it is morphologically similar and often occurs sympatrically (Levanidova & Zhiltzova 1979). Phylogenetic anlaysis indicates that this species shares a recent common ancestor with S. teleckojensis (Zwick, Levanidova & Zhiltzova 1971). ENM modeling suggests that this species is likely to occur farther east in Mongolia (Fig. 125).

description: Σκοπός της παρούσας εργασίας αποτελεί η μελέτη και κατανόηση των νευρωνικών δικτύων και της μηχανικής μάθησης γενικότερα, έπειτα από την εφαρμογή τους σε ένα σετ χρονοσειρών χρηματιστηρίου, το οποίο αποτελείται από γνωστές εταιρίες πληροφορικής. Το πρόβλημα της δημιουργίας προβλέψεων για τιμές χρηματιστηρίου, γίνεται ολοένα και πιο περιζήτητο, αφού αυξάνεται συνεχώς το μέγεθος των δεδομένων που μπορούν να χρησιμοποιηθούν για την εκπαίδευση και μελέτη αλγορίθμων. Επιπρόσθετα, αποτελεί πρόκληση η εύστοχη πρόβλεψη χρηματιστηριακών τιμών τόσο για τις ίδιες τις εταιρείες όσο και για ιδιώτες που ασχολούνται ενεργά με αυτό τον κλάδο. Τα νευρωνικά δίκτυα με τα οποία θα ασχοληθούμε, αποτελούν μέθοδο Βαθιάς Μάθησης και είναι μέρος της Τεχνητής Νοημοσύνης. Είναι υπολογιστικά συστήματα εμπνευσμένα από τα βιολογικά νευρωνικά δίκτυα του ανθρώπινου εγκεφάλου. Έτσι ο αρχικός σκοπός τους ήταν να δώσουν λύσεις σε προβλήματα, με τον ίδιο τρόπο που δίνει λύσεις ο ανθρώπινος εγκέφαλος. Στη συγκεκριμένη εργασία, θα ασχοληθούμε εκτενέστερα με δύο είδη επαναλαμβανόμενων νευρωνικών δικτύων και ένα είδος Perceptron. Ξεκινάμε την εργασία, παρουσιάζοντας κάποια εισαγωγικά στοιχεία, όσον αφορά την μηχανική μάθηση και τα είδη της. Στο Κεφάλαιο 2, αναφερόμαστε στα χαρακτηριστικά των χρονοσειρών. Στη συνέχεια στο Κεφάλαιο 3 αναλύονται οι διάφοροι αλγόριθμοι πρόβλεψης, αναλόγως το διαθέσιμο σύνολο δεδομένων κάθε φοράς και η εργασία προχωρά στο Κεφάλαιο 4 όπου αναλύονται βασικά Νευρωνικά Δίκτυα που θα χρησιμοποιηθούν στην πορεία για το πειραματικό μέρος. Τέλος, στο Κεφαλαίο 5 με την βοήθεια των χρονοσειρών Amazon, Google, Apple μοντελοποιούνται τα νευρωνικά δίκτυα του κεφαλαίου 4 και αξιολογούνται με κατάλληλα μέτρα αξιολόγησης ως προς την ικανότητα πρόβλεψης μελλοντικών τιμών.

description: We study the collective dynamics of a clean Floquet system of cold atoms, numerically simulating two realistic set-ups based on a regular chain of interacting Rydberg atoms driven by laser fields. In both cases, the population evolution and its Fourier spectrum display clear signatures of a discrete time crystal (DTC), exhibiting the appearance of a robust subharmonic oscillation which persists on a time scale increasing with the chain size, within a certain range of control parameters. We also characterize how the DTC stability is affected by dissipative processes, typically present in this atomic system even though the Rydberg state is very long lived.

 Latohexapus granosus Huang et al., 2002: 656, figs. 1B, 3, 4; Ng et al., 2008: 86.
 Material examined. Holotype: male (16.3 × 8.2 mm) (ZRC 2002.001), port at Bertzuliau, Yulin County, Taiwan, coll. P.-Y. Hsu, 23 March 2000.
 Diagnosis. Carapace about 1.9 times as broad as long, dorsal surface distinctly granulated; regions separated by deep grooves; anterolateral margin arcuate; posterolateral corner with small angle over base of posterior pereopods (Fig. 54A). Orbit distinct, transverse; eye movable (Fig. 54A, B). Pterygostomial region with row of oblique striae (Fig. 54B). Third maxillipeds broad, completely covering buccal cavity; exopod with well developed flagellum (Fig. 54B, C). Chelipeds asymmetrical; major chela with wide gap when fingers closed, granulated (Fig. 54C); minor chela with narrower gap when fingers closed; ornamentation similar to that of major chela. P2–P4 relatively short; P3 longest, surfaces granulated; deep longitudinal groove on lateral face of merus of P4 (Fig. 54A). Male thoracic sternum very broad (Fig. 54C); sternites 1, 2 fused, strongly bent inwards towards buccal cavity; thoracic sternal groove extending obliquely from edge of abdominal cavity, bending to become subparallel to frontal margin to base of chelipeds; sternoabdominal cavity reaching base of sternite 3; sternite 8 exposed, triangular, as long as abdominal somite 1. Male abdomen relatively narrow (Fig. 54C), surface granular; somites 3–5 fused, lateral margin sinuous; somite 6 with median part of lateral margin prominently expanded into triangular projection, appearing evenly hexagonal; telson rounded. G1 slender, bent submedially, directed anterolaterally, distal part tapered, not concealed under abdomen.
 Colour. In life, the carapace and appendages are dirty white overall, but stained black in many parts by the mud.
 Remarks. Huang et al. (2002) gave a relatively complete description and figures of the genus and species, and there is no need to repeat it. One useful character not used by Huang et al. (2002) is the form of thoracic sternites 1 and 2. Latohexapus is the only genus known to have thoracic sternites 1 and 2 sharply bent inwards and downwards into the buccal cavity (Fig. 54B, C).
 Type locality. Bertzuliau, Yulin County, Taiwan.
 Distribution. Yulin County, Taiwan. Subtidal.

description: This article gives an overview of what Fog computing is, its uses and the comparison between Fog computing and Cloud computing. Cloud is performing well in todays World and boosting the ability to use the internet more than ever. Cloud computing gradually developed a method to use the benefits of it in most of the organizations. Fog computing can be apparent both in big data structures and large cloud systems, making reference to the growing complications in retrieving the data accurately. Fog computing is outspreading cloud computing by transporting computation on the advantage of network systems such as cell phone devices or fixed nodes with in-built data storage. Fog provides important points of improved abilities, strong security controls, and processes, establish data transmission capabilities carefully and in a flexible manner. This paper gives an overview of the connections and attributes for both Fog computing and cloud varies by outline, preparation, directions, and strategies for associations and clients. This also explains how Fog computing is flexible and provide better service for data processing by overwhelming low network bandwidth instead of moving whole data to the cloud platform.

description: Let us call a function $f$ from a space $X$ into a space $Y$ preserving if the image of every compact subspace of $X$ is compact in $Y$ and the image of every connected subspace of $X$ is connected in $Y$. By elementary theorems a continuous function is always preserving. Evelyn R. McMillan proved in 1970 that if $X$ is Hausdorff, locally connected and Frechet, $Y$ is Hausdorff, then the converse is also true: any preserving function $f:X\to Y$ is continuous. The main result of this paper is that if $X$ is any product of connected linearly ordered spaces (e.g. if $X = R^κ$) and $f:X \to Y$ is a preserving function into a regular space $Y$, then $f$ is continuous.

description: We present a volume-limited, spectroscopically-verified sample of M7$-$L5 ultracool dwarfs within 25\,pc. The sample contains 410 sources, of which $93\%$ have trigonometric distance measurements ($80\%$ from \textit{Gaia} DR2), and $81\%$ have low-resolution ($R\sim120$), near-infrared (NIR) spectroscopy. We also present an additional list of 60 sources which may be M7$-$L5 dwarfs within 25\,pc when distance or spectral type uncertainties are taken into account. The spectra provide NIR spectral and gravity classifications, and we use these to identify young sources, red and blue $J-K_S$ color outliers, and spectral binaries. We measure very low gravity and intermediate gravity fractions of $2.1^{+0.9}_{-0.8}\%$ and $7.8^{+1.7}_{-1.5}\%$, respectively; fractions of red and blue color outliers of $1.4^{+0.6}_{-0.5}$\% and $3.6^{+1.0}_{-0.9}$\%, respectively; and a spectral binary fraction of $1.6^{+0.5}_{-0.5}\%$. We present an updated luminosity function for M7$-$L5 dwarfs continuous across the hydrogen burning limit that agrees with previous studies. We estimate our completeness to range between $69-80\%$ when compared to an isotropic model. However, we find that the literature late-M sample is severely incomplete compared to L dwarfs, with completeness of $62^{+8}_{-7}\%$ and $83^{+10}_{-9}\%$, respectively. This incompleteness can be addressed with astrometric-based searches of ultracool dwarfs with \textit{Gaia} to identify objects previously missed by color- and magnitude-limited surveys.
