description: This paper explores the purpose of walks for co-residing carers of people with dementia, using a social citizenship lens. The findings are based on the first phase of a study examining the everyday experiences of place, space and neighbourhood of dementia carers. Using three forms of data collection - social network mapping, walking interviews, and participant-driven photography – the study brings forth information about why carers go on walks either alone or with the person with dementia. Carers explained that walks facilitate their connections with themselves, the person with dementia, their social environment, and their natural and built environment. In sum, walks provide a way of practicing and sustaining social citizenship. Carers’ discourse about walks highlights their personal, everyday practices and strategies, as well as the larger tensions and contradictions of dementia care. The findings reinforce the need to bring into dialogue, from a carer perspective, a social citizenship model of dementia with the growing interest in dementia-friendly communities.

description: The paper examined the reliability of the Nigerian grown Ara and Apado timber species as column materials. The work centers on the compressive strength characteristics of Nigerian Ara (Pterocarpus erinaceus) and Apado (Berlinia spp) timber column of nominal lengths 200, 400, 600 and 800 mm and cross section of 50 by 50 mm. The steps involved collection and conditioning of Apa and Apado timber species, preparation of test specimens, determination of physical and compressive strength properties and derivation of continuous column design equations. Twenty (20) test samples were used for all the tests carried out. Apa and Apado have an average density of 652.74 and 472.60 kg/m3, respectively. Moisture content of both species less than the maximum recommended value of 20 % and the average strength at yield of Apa and Apado were 35.65 and 14.00 N/mm2. The derived continuous equations for design of Apa and Apado column are and respectively. Ara and Apado have the reliability index of 0.63 and 0.65 respectively for a service life of 50 years, assuming other serviceability conditions are met. The paper therefore recommends the adoption of these equations for the design of compression members from these timber species, in Nigeria.

description: Quantum confinement is a restriction on the motion of electrons in a material to specific region, resulting in discrete energy levels rather than continuous energy bands. In certain materials quantum confinement could dramatically reshape the electronic structure and properties of the surface with respect to the bulk. Here, in the recently discovered kagome superconductor CsV$_3$Sb$_5$ (A=K, Rb, Cs) family of materials, we unveil the dominant role of quantum confinement in determining their surface electronic structure. Combining angle-resolved photoemission spectroscopy (ARPES) measurement and density-functional theory simulation, we report the observations of two-dimensional quantum well states due to the confinement of bulk electron pocket and Dirac cone to the nearly isolated surface layer. The theoretical calculations on the slab model also suggest that the ARPES observed spectra are almost entirely contributed by the top two layers. Our results not only explain the disagreement of band structures between the recent experiments and calculations, but also suggest an equally important role played by quantum confinement, together with strong correlation and band topology, in shaping the electronic properties of this family of materials.

description: En el ámbito de la responsabilidad civil puede darse el caso en el que la reparación genere una situación compleja desde el punto de vista de la equidad, porque el agente que debe responder por el daño causado puede quedar en la posición de tener una obligación impagable que agravará su precaria condición social y acentuará una desigualdad sustantiva que padece de antemano. Así, es posible que el daño causado a una persona de escasos recursos a manos de un agente adinerado se traduzca en una situación que deje a la víctima formalmente reparada, pero desde su pobreza, porque se indemnizará conforme a sus condiciones al momento de la ocurrencia del daño, lo que perpetuará las dificultades de acceder a mejores condiciones de vida. El presente trabajo busca poner de presente esa realidad y formular algunos planteamientos generales que faciliten una solución, para lo cual se tomará como referencia el caso del lucro cesante en Colombia, de manera que pueda aportarse a la atenuación de las situaciones de regresividad que se pueden generar dentro de la responsabilidad civil, y así no afectar sustantivamente la autonomía de los intervinientes en el encuentro social dañoso.
description: In the field of civil liability there may be a case in which the reparation generates a complex situation from the point of view of equity, because the agent who must respond for the damage caused may be left in the position of having an unpayable obligation that will aggravate his precarious social condition and accentuate a substantive inequality that he suffers beforehand. Thus, it is possible that the damage caused to a person of scarce resources at the hands of a wealthy agent results in a situation that leaves the victim formally repaired, but from his poverty, because he will be compensated according to his conditions at the time of the occurrence of the damage, which will perpetuate the difficulties of access to better living conditions. This paper seeks to present this reality and formulate some general approaches to facilitate a solution, for which the case of loss of profits in Colombia will be taken as a reference, so that it can contribute to the attenuation of regressive situations that can be generated within the civil liability, and thus not substantially affect the autonomy of those involved in the harmful social encounter.

description: Purpose: In this study, we aimed to identify trajectories of physical activity in a cohort of women over a 1-year period after treatment for breast cancer. We also examined factors that could predict trajectory group membership. Methods: We collected data from 199 women using questionnaires at baseline (mean = 3.46 months after treatment), and 3, 6, 9, and 12 months thereafter. Results: Based on semiparametric group-based modeling, there were five trajectories: consistently inactive, decreasing levels, inactive with increasing levels, somewhat active, and consistently sufficiently active. Based on logistic regression analysis, women who reported higher levels of depressive symptoms and fatigue were less likely to remain consistently sufficiently active, and women who reported higher levels of cancer worry were more likely to remain consistently sufficiently active. Age, stage of cancer, time since treatment, number of treatment types received, and number of physical symptoms did not predict trajectory group membership. Conclusions: Women do not have uniform physical activity trajectories after treatment for breast cancer. Identification subgroups of women who do not remain consistently sufficiently active, and factors that predict these trajectories, can aid in the development of targeted behavior change interventions.
An Analysis of U.S. Patent #5,243,538 “Comparison and Verification System for Logic Circuits and Method Thereof"

description: On Sept. 7, 1993, U. S. Patent Number 5,243,538 was awarded to four Hitachi employees for a technique for comparing logic circuits using Binary Decision Diagrams (BDDs). Although the U. S. patent application was filed on Aug. 7, 1990, they had filed for a patent in Japan on Aug. 9, 1989, and hence this earlier date should be used in determining the prior art. The key property exploited by the patentees is that by generating the BDDs for the two logic circuits according to a unique ordering of the variables, the task of comparing the BDDs is greatly simplified. The patentees did not cite and apparently were not aware of work done on BDD-based logic comparison during the 9 years between the cited papers by S. B. Akers and their patent application. In particular, the author devised a technique for generating and comparing logic functions using Ordered (i.e., assuming a unique ordering of variables) BDDs in 1984. Papers published in 1985 (Design Automation Conference) and 1986 (IEEE Transactions on Computers) describe this method in detail. We assert that this patent should not have been issued, as it attempts to patent prior art.

description: Macroalgae play an important role in maintaining the overall balance of the planet, not only through oxygen production but also due to their importance as the foundation of food webs, climate regulation, habitats, nutrient cycles, and their commercial value to living organisms. They have a profound impact on global climate and on the daily lives of humans. Their conservation and protection are essential for maintaining the health of our oceans and the planet. The main objective of this study was to determine the presence of marine macroalgae along the coastal profile of the central zone of Manabí. Three zones were strategically selected for their composition: Punta Blanca-Jaramijó (-0.929036, -80.666193), Barbasquillo-Manta (-0.94373, -80.75463), and Puerto López-Jipijapa (-1.09456, -80.89857), where algal species samples were collected for identification according to established protocols. A total of 18 macroalgae species were identified, belonging to three phyla: Chlorophyta, Heterokontophyta, and Rhodophyta, with Lobophora variegata (41) being the most frequently recorded species, corresponding to the phylum Heterokontophyta, class Phaeophyta. Regarding the bromatological analyses, significant results were obtained in all samples, as well as for minerals, providing guidelines for future beneficial research. The ecotoxicological tests (heavy metals) showed values above the permissible normal indices, highlighting the need to consider these results for the conservation and recovery of contaminated areas.
Efficient Wave Optics Modeling of Nanowire Solar Cells Using Rigorous Coupled Wave Analysis

Publisher: name: My University
Year: 2019

description: We investigate the accuracy of rigorous coupled wave analysis (RCWA) for near-field computations within cylindrical GaAs nanowire solar cells and discover excellent accuracy with low computational cost at long incident wavelengths, but poor accuracy at short incident wavelengths. These near fields give the carrier generation rate, and their accurate determination is essential for device modeling. We implement two techniques for increasing the accuracy of the near fields generated by RCWA, and give some guidance on parameters required for convergence along with an estimate of their associated computation times. The first improvement removes Gibbs phenomenon artifacts from the RCWA fields, and the second uses the extremely well-converged far field absorption to rescale the local fields. These improvements allow a computational speedup between 30 and 1000 times for spectrally integrated calculations, depending on the density of the near fields desired. Some spectrally resolved quantities, especially at short wavelengths, remain expensive, but RCWA is still an excellent method for performing those calculations. These improvements open up the possibility of using RCWA for low cost optical modeling in a full optoelectronic device model of nanowire solar cells.

description: We present various results concerning the two-weight Hardy's inequality on infinite trees. Our main scope is to survey known characterizations (and proofs) for trace measures, as well as to provide some new ones. Also for some of the known characterizations we provide here new proofs. In particular, we obtain a new characterization based on a new reverse Hölder inequality for trace measures, and one based on the well known Muckenhoupt-Wheeden-Wolff inequality, of which we here give a new probabilistic proof. We provide a new direct proof for the so called isocapacitary characterization and a new simple proof, based on a monotonicity argument, for the so called mass-energy characterization. Furthermore, we introduce a conformally invariant version of the two-weight Hardy's inequality, we characterize the compactness of the Hardy operator, we provide a list of open problems and suggest some possible lines of future research.

description: Background: Physical activity (PA) is an integral part of healthcare for the general population and individuals with psychiatric disorders. However, PA is significantly more complex for and related to both healthy (e.g., reduced anxiety and depressive symptoms) and unhealthy outcomes (e.g., intrusive, repetitive thoughts that lead to abnormally high levels of PA) among women with an eating disorder (ED). Consequently, many healthcare professionals recommend abstinence from PA during ED treatment. Despite this, women may remain engaged in PA during ED treatment or resume PA shortly thereafter. Little has been done to understand women’s PA behaviors and attitudes and to explore how they integrate PA into their lives during and after ED treatment. Thus, this study sought to explore PA behaviors and attitudes among women with an ED. Methods: Nine women who self-reported receiving an ED diagnosis participated in semi-structured interviews, which were transcribed and analysed thematically. Results: Six interrelated themes were constructed to represent participants’ PA experiences: PA as a lifestyle, PA can be beneficial, How I feel when I can’t do PA, Being cautious about PA, Reactions to healthcare professionals’ practice of recommending abstinence from PA during ED treatment, and PA programming thoughts. Conclusions: Overcoming dysfunctional PA behaviors (e.g., engaging in abnormally high levels of PA) and attitudes (e.g., associating PA with caloric expenditure) can be a long and complicated journey for women with an ED. Nevertheless, women with an ED want PA to be integrated into their ED treatment protocol for two key reasons, namely to accrue the benefits associated with PA and to learn how to engage in PA in adaptive and healthy ways.

description: Abstract: "Before we hear the familiar phrase 'All systems are go' just prior to the launch of a space shuttle, thousands of operations and tests have been performed to ensure that all shuttle and support subsystems are operational and ready for launch. These steps, which range from activating the orbiter's flight computers to removing the launch pad from the itinerary of the NASA tour buses, are carried out by launch team members at various locations and with highly specialized fields of expertise. The responsibility for coordinating these diverse activities rests with the NASA Test Director (NTD) at Kennedy Space Center.We are studying the behavior of the NTD with the goal of building a detailed computational model of that behavior; this paper describes the results of our analysis to date. We describe the NTD's performance in detail, as a team member who must coordinate a complex task though efficient audio communication, as well as an individual taking notes and consulting manuals. A model of the routine cognitive skills employed by the NTD to follow the launch countdown procedure manual has been implemented using the Soar cognitive architecture. The paper concludes with several examples of how such a model could aid in evaluating proposed computer support systems."

description: We present a model of set theory, in which, for a given $n\ge2$, there exists a non-ROD-uniformizable planar lightface $\varPi^1_n$ set in $\mathbb R\times\mathbb R$, whose all vertical cross-sections are countable sets (and in fact Vitali classes), while all planar boldface $\bfΣ^1_n$ sets with countable cross-sections are $\bfΔ^1_{n+1}$-uniformizable. Thus it is true in this model, that the ROD-uniformization principle for sets with countable cross-sections first fails precisely at a given projective level.

description: In this work we explore an instance of the $τ$-function of vertex type operators, specified in terms of a constant phase shift in a free-fermionic basis. From the physical point of view this $τ$-function has multiple interpretations: as a correlator of Jordan-Wigner strings, a Loschmidt Echo in the Aharonov-Bohm effect, or the generating function of the local densities in the Tonks-Girardeau gas. We present the $τ$-function as a form-factors series and tackle it from four vantage points: (i) we perform an exact summation and express it in terms of a Fredholm determinant in the thermodynamic limit, (ii) we use bosonization techniques to perform partial summations of soft modes around the Fermi surface to acquire the scaling at zero temperature, (iii) we derive large space and time asymptotic behavior for the thermal Fredholm determinant by relating it to effective form-factors with an asymptotically similar kernel, and (iv) we identify and sum the important basis elements directly through a tailor-made numerical algorithm for finite-entropy states in a free-fermionic Hilbert space. All methods confirm each other. We find that, in addition to the exponential decay in the finite-temperature case the dynamic correlation functions exhibit an extra power law in time, universal over any distribution and time scale.

description: The automatic recognition of a person's emotional state has become a very active research field that involves scientists specialized in different areas such as artificial intelligence, computer vision or psychology, among others. Our main objective in this work is to develop a novel approach, using persistent entropy and neural networks as main tools, to recognise and classify emotions from talking-face videos. Specifically, we combine audio-signal and image-sequence information to compute a topology signature(a 9-dimensional vector) for each video. We prove that small changes in the video produce small changes in the signature. These topological signatures are used to feed a neural network to distinguish between the following emotions: neutral, calm, happy, sad, angry, fearful, disgust, and surprised. The results reached are promising and competitive, beating the performance reached in other state-of-the-art works found in the literature.
The Revival of the Far-Right in Italian Politics: A Visual Narrative Analysis of Images of Giorgia Meloni
Creators: name: Braccio, Luca
Publisher: name: My University
Year: 2023

description: This paper uses visual narrative analysis and the strategy of layering to study five images of Italian Prime Minister Giorgia Meloni. I argue Meloni has used the medium of images to push her political agenda and legitimize her power. By doing so, this paper aims to answer the question: how does the Italian far-right mobilize images in order to frame and amplify their political agendas? With this, I find that Meloni has been able to effectively use images to evoke emotion, frame her ideas, and gain popularity among Italian voters. Moreover, I find that Meloni has also been able to insert herself into a larger far-right movement that has taken place across the world. Theoretically, this paper contributes to a popular area of international relations scholarship which covers visual narrative analysis writ large.

description: We consider variational principles related to V. I. Arnold's stability criteria for steady-state solutions of the two-dimensional incompressible Euler equation. Our goal is to investigate under which conditions the quadratic forms defined by the second variation of the associated functionals can be used in the stability analysis, both for the Euler evolution and for the the Navier-Stokes equation at low viscosity. In particular, we revisit the classical example of Oseen's vortex, providing a new stability proof with stronger geometric flavor. Our analysis involves a fairly detailed functional-analytic study of the inviscid case, which may be of independent interest, and a careful investigation of the influence of the viscous term in the particular example of the Gaussian vortex.

description: Research on damage detection of road surfaces using image processing techniques has been actively conducted, achieving considerably high detection accuracies. Many studies only focus on the detection of the presence or absence of damage. However, in a real-world scenario, when the road managers from a governing body need to repair such damage, they need to clearly understand the type of damage in order to take effective action. In addition, in many of these previous studies, the researchers acquire their own data using different methods. Hence, there is no uniform road damage dataset available openly, leading to the absence of a benchmark for road damage detection. This study makes three contributions to address these issues. First, to the best of our knowledge, for the first time, a large-scale road damage dataset is prepared. This dataset is composed of 9,053 road damage images captured with a smartphone installed on a car, with 15,435 instances of road surface damage included in these road images. In order to generate this dataset, we cooperated with 7 municipalities in Japan and acquired road images for more than 40 hours. These images were captured in a wide variety of weather and illuminance conditions. In each image, we annotated the bounding box representing the location and type of damage. Next, we used a state-of-the-art object detection method using convolutional neural networks to train the damage detection model with our dataset, and compared the accuracy and runtime speed on both, using a GPU server and a smartphone. Finally, we demonstrate that the type of damage can be classified into eight types with high accuracy by applying the proposed object detection method. The road damage dataset, our experimental results, and the developed smartphone application used in this study are publicly available (https://github.com/sekilab/RoadDamageDetector/).

description: What kind of culture do citizens value? How do they assess what is a cultural activity and how does this activity fit within the everyday life of communities? To what extent is cultural capital linked with the social capital of the community? This study makes use of the Our Millennium database, which was a special initiative of the Community Foundations of Canada (CFC) to mark the new century, to try to answer these questions. In 1999 and 2000, the CFC invited Canadians to make lasting millennium “gifts” to their communities to make them a better place and to register these gifts on an on-line database. These gifts could be made under 11 self-selected theme areas. An assessment of the Our Millennium initiative by the Caledon Institute of Social Policy remarked upon the disproportionate number of projects that featured various aspects of arts, culture and heritage.This study delves more deeply into the Caledon Insitute’s conclusion and, using a social and cultural capital lens, explores why arts, cultural and heritage projects were so prominent among the millennium gifts registered on the Our Millennium database.
Evidence for precession due to supercritical accretion in ultraluminous X-ray sources

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Most ultraluminous X-ray sources (ULXs) are thought to be supercritical accreting compact objects, where massive outflows are inevitable. Using the long-term monitoring data with the Swift X-ray Telescope, we identified a common feature in bright, hard ULXs: they display a quasi-periodic modulation in their hard X-ray band but not in their soft band. As a result, some sources show a bimodal distribution on the hardness intensity map. We argue that these model-independent results can be well interpreted in a picture that involves supercritical accretion with precession, where the hard X-ray emission from the central funnel is more or less beamed, while the soft X-rays may arise from the photosphere of the massive outflow and be nearly isotropic. It implies that precession may be ubiquitous in supercritical systems, such as the Galactic microquasar SS~433. How the hard X-rays are modulated can be used to constrain the angular distribution of the hard X-ray emission and the geometry of the accretion flow. We also find that two ULX pulsars (NGC 5907 ULX-1 and NGC 7793 P13) show similar behaviors but no bimodal distribution, which may imply that they have a different beaming shape or mechanism.

Sono presenti contributi elaborati sia da giovani ricercatori della Scuola di Dottorato della Sapienza sia da affermate personalità della comunità scientifica, italiane e francesi, con lo scopo di mettere a confronto le metodologie e i risultati. L’obiettivo del lavoro è dunque quello di presentare lo status quaestionis sul tema dell’ideologia funeraria nella città e nel territorio di Veio, dalle origini fino alla definitiva conquista romana: sono stati presi in esame i dati restituiti dalle recenti scoperte e dalle indagini più aggiornate sulle necropoli. Una sezione è poi dedicata al confronto tematico con altre realtà dell’Etruria e dell’area medio-adriatica, mentre l’ultima parte analizza i cosiddetti indicatori dell’ideologia: quegli aspetti specifici che, nel corso della ricerca archeologica, forniscono informazioni chiave per la ricostruzione del complesso e articolato mosaico dell’ideologia, sottesa alla dimensione funeraria di una società antica.

description: Graph coloring is the de facto standard technique for register allocation within a compiler. In this paper we examine the importance of the quality of the coloring algorithm and various extensions of the basic graph coloring technique by replacing the coloring phase of the GNU compiler’s register allocator with an optimal coloring algorithm. We then extend this optimal algorithm to incorporate various extensions such as coalescing and preferential register assignment. We find that using an optimal coloring algorithm has surprisingly little benefit and empirically demonstrate the benefit of the various extensions.

description: We present a very simple proof that the $O(n)$ model satisfies a uniform logarithmic Sobolev inequality (LSI) if the positive definite coupling matrix has largest eigenvalue less than $n$. This condition applies in particular to the SK spin glass model at inverse temperature $β< 1/4$. It is the first result of rapid relaxation for the SK model and requires significant cancellations between the ferromagnetic and anti-ferromagnetic spin couplings that cannot be obtained by existing methods to prove Log-Sobolev inequalities. The proof also applies to more general bounded and unbounded spin systems. It uses a single step of zero range renormalisation and Bakry--Emery theory for the renormalised measure.

description: Previous studies have demonstrated that patients have poor understanding of the discharge instructions provided from the emergency department (ED). The aims of this study are to determine if patient factors, such as income and level of education, correlate with patient understanding of discharge instructions and to explore if different patient populations prefer different resources for receiving discharge instructions.

description: The PDE approach developed earlier by the first three authors for $L^\infty$ estimates for fully non-linear equations on Kähler manifolds is shown to apply as well to Monge-Ampère and Hessian equations on nef classes. In particular, one obtains a new proof of the estimates of Boucksom-Eyssidieux-Guedj-Zeriahi and Fu-Guo-Song for the Monge-Ampère equation, together with their generalization to Hessian equations.

description: The Soft X-ray Imager (SXI) is an imaging spectrometer using charge-coupled devices (CCDs) aboard the Hitomi X-ray observatory. The SXI sensor has four CCDs with an imaging area size of $31~{\rm mm} \times 31~{\rm mm}$ arranged in a $2 \times 2$ array. Combined with the X-ray mirror, the Soft X-ray Telescope, the SXI detects X-rays between $0.4~{\rm keV}$ and $12~{\rm keV}$ and covers a $38^{\prime} \times 38^{\prime}$ field-of-view. The CCDs are P-channel fully-depleted, back-illumination type with a depletion layer thickness of $200~μ{\rm m}$. Low operation temperature down to $-120~^\circ{\rm C}$ as well as charge injection is employed to reduce the charge transfer inefficiency of the CCDs. The functionality and performance of the SXI are verified in on-ground tests. The energy resolution measured is $161$-$170~{\rm eV}$ in full width at half maximum for $5.9~{\rm keV}$ X-rays. In the tests, we found that the CTI of some regions are significantly higher. A method is developed to properly treat the position-dependent CTI. Another problem we found is pinholes in the Al coating on the incident surface of the CCDs for optical light blocking. The Al thickness of the contamination blocking filter is increased in order to sufficiently block optical light.

description: Due to imbalances in the global transport of containerised goods, liner shipping companies go to great lengths to match the regional supply and demand for empty containers by transporting equipment from surplus to deficit regions. Making accurate forecasts of regional empty container availability could support liner companies and other involved actors by taking better relocation decisions and thus avoid unnecessary transportation costs of empty equipment. Against this background, this paper introduces two novel approaches based on machine learning and probabilistic techniques to predict the future availability of empty containers for more than 280 locations worldwide. The machine learning and probabilistic prediction models are built by analysing a unique data set of more than 100 million events from past container journeys. These events represent different stages during the transport process of a container. Both models use a two-step forecast logic: First, the expected future location of a container is predicted. Second, the expected timestamp for arriving at that location is estimated. The machine learning model uses artificial neural networks and mixture density networks to forecast the movements of containers. The models are quantitatively assessed and compared to the actual availability of containers and two more conventional forecasting approaches. The results indicate that the probabilistic prediction approach can keep up with conventional approaches while the neural network approach significantly outperforms the other approaches concerning every evaluation metric.
An Algorithmic Framework for Strategic Fair Division

description: We study the paradigmatic fair division problem of fairly allocating a divisible good among agents with heterogeneous preferences, commonly known as cake cutting. Classic cake cutting protocols are susceptible to manipulation. Do their strategic outcomes still guarantee fairness? To address this question we adopt a novel algorithmic approach, proposing a concrete computational model and reasoning about the gametheoretic properties of algorithms that operate in this model. Specifically, we show that each protocol in the class of generalized cut and choose (GCC) protocols — which includes the most important discrete cake cutting protocols — is guaranteed to have approximate subgame perfect Nash equilibria, or even exact equilibria if the protocol’s tie-breaking rule is flexible. We further observe that the (approximate) equilibria of proportional protocols — which guarantee each of the n agents a 1/n-fraction of the cake — must be (approximately) proportional, thereby answering the above question in the positive (at least for one common notion of fairness).

description: Mott insulators with large and active (or multiflavor) local Hilbert spaces widely occur in quantum materials and ultracold atomic systems, and are dubbed "multiflavor Mott insulators". For these multiflavored Mott insulating materials, the spin-only description with the quadratic spin interactions is often insufficient to capture the major physical processes. In the situation with active orbitals, the Kugel-Khomskii superexchange model was then proposed. We briefly review this historical model and discuss the modern developments beyond the original spin-orbital context. These include and are not restricted to the $4d$/$5d$ transition metal compounds with the spin-orbit-entangled $J=3/2$ quadruplets, the rare-earth magnets with two weakly-separated crystal field doublets, breathing magnets and/or the cluster and molecular magnets, et al. We explain the microscopic origin of the emergent Kugel-Khomskii physics in each realization with some emphasis on the $J=3/2$ quadruplets, and refer the candidate multiflavor Mott insulators as "$J=3/2$ Mott insulators". For the ultracold atoms, we review the multiflavor Mott insulator realization with the ultracold alkaline and alkaline-earth atoms on the optical lattices. Despite a large local Hilbert space from the atomic hyperfine spin states, the system could naturally realize a large symmetry group such as the Sp($N$) and SU($N$) symmetries. These ultracold atomic systems lie in the large-$N$ regime of these symmetry groups and are characterized by strong quantum fluctuations. The Kugel-Khomskii physics and the exotic quantum ground states with the "baryon-like" physics can appear in various limits. We conclude with our vision and outlook on this subject.
