description: Most agricultural practices have focused on high volume of produces by using chemicals. Currently consumers highly focus on the safety of food and agricultural produces that increases trend of green and organic consumption resulting in increasing organic farming. This study aimed to analyze factors affecting development of organic farming; to investigate guidelines of sustainable organic farming management; and promote networking of organic farming on the path of growth under Thailand 4.0 in the EEC. Data collection was conducted via questionnaire to farmers practicing organic farming in three provinces in the EEC, with 150 farmers in each province, 450 in total, as well as interviews with officials of District Agricultural Extension offices, organic farmers, and network leaders. Data analysis was conducted using descriptive statistics and content analysis. Factors affecting the development of organic farming consisted of sufficient production and management according to the organic farming standards, and farmers’ accessibility; efficient and appropriate production system management; potential in farming of organic vegetables; good attitude towards organic farming; marketing of organic farming; and attention to health and consumers’ organic vegetables. All these factors are in accordance with the organic productivity, income and health. In addition, organic farming is environmentally friendly. Guidelines for development of the organic farming include marketing, logistics, and standards for organic products such as promotion of production and creation of self-reliant networks; support changes in production to secure sustainable farming; drive pilot projects to integrate the development of organic farming; and integration of the development of production and marketing.

description: We study the atomic structure of twisted bilayer graphene, with very small mismatch angles ($θ\sim 0.28^0$), a topic of intense recent interest. We use simulations, in which we combine a recently presented semi-empirical potential for single-layer graphene, with a new term for out-of-plane deformations, [Jain et al., J. Phys. Chem. C, 119, 2015] and an often-used interlayer potential [Kolmogorov et al., Phys. Rev. B, 71, 2005]. This combination of potentials is computationally cheap but accurate and precise at the same time, allowing us to study very large samples, which is necessary to reach very small mismatch angles in periodic samples. By performing large scale atomistic simulations, we show that the vortices appearing in the Moiré pattern in the twisted bilayer graphene samples converge to a constant size in the thermodynamic limit. Furthermore, the well known sinusoidal behavior of energy no longer persists once the misorientation angle becomes very small ($θ<1^0$). We also show that there is a significant buckling after the relaxation in the samples, with the buckling height proportional to the system size. These structural properties have direct consequences on the electronic and optical properties of bilayer graphene.

description: Dem Führungshandeln von Schulleitenden wurde in den letzten Jahrzehnten immer mehr Beachtung geschenkt. Oft ging und geht es dabei um die Frage, welche Art von Führungshandeln wirksam im Hinblick auf den Lernerfolg von Schülerinnen und Schüler ist. Besondere Beachtung fanden dabei verschiedene Arten von Führungshandeln, beispielsweise transformationale und unterrichtsbezogene Führung (Instructional Leadership) oder auch situative und verteilte Führung. Im anglophonen Raum hat das Konzept des lernzentrierten Leitungshandelns (Leadership for Learning) in den letzten 15 Jahren an Bekanntheit gewonnen. Inzwischen wird es auch zunehmend in deutschsprachigen Ländern diskutiert. Welches Verständnis verbirgt sich dahinter? Was ist bekannt über die Effekte von Führungshandeln in der Schule allgemein und im Zusammenhang mit lernzentriertem Leitungshandeln im Speziellen?

description: In Switzerland, baccalaureate school is still considered to be the royal road to a university education and the elite path for the social reproduction of the upper class. However, cantonal enrollment to baccalaureate school varies widely due to Swiss federalism. There is a recurring debate on whether access to baccalaureate school is fair and equal among pupils who live in different cantons and who are of different social origin. This paper aims to analyze how the institutional conditions of cantons and municipalities impact a pupil’s probability of entering baccalaureate school and how the cantonal provisioning of places in baccalaureate school affects social inequality of access. For our theoretical foundation, we combine concepts of neo-institutionalism with mechanisms of social reproduction in education. Empirically, we analyze national longitudinal register data to model educational transitions from compulsory to baccalaureate school by using logistic regression models. Our results show that institutional structures at the cantonal and municipal levels influence the probability of transition beyond individual pupils’ characteristics. The degree of inequality varies between cantons, depending on the supply of baccalaureate school places. Inequality first increases with an increasing number of places (the scissors effect) and decreases only after the demand of more privileged families for places at baccalaureate school is saturated.
title: Memory in the present: on video game preservation by fans in cyberspace
Creators: name: Watson, Lauren
Publisher: name: University of Glasgow
Year: 2023

description: This thesis contributes to the vital scholarly analysis of contemporary retro video game preservation by arguing that games are currently preserved not by freezing them, but by transforming them. By extension, video games’ textual transformation characterises their cultural memory as a constant emergence. I will show this by analysing how games are distributed, contextualised, and then discovered within retro-game fans’ rogue archival networks, and how each aspect of these networks encourage a distinctly transformative, collaborative construction of retro-gaming cultural memory. I begin by exploring fan-built retro-game distribution sites as digital archival networks which show the value that fans place upon the ability to actively play games, alongside how new media environments influence the construction of retro-game cultural memory. The second chapter then looks at extra-textual fanproductions and critical assessments of ephemeral aspects of gameplay concerning the Dance Dance Revolution (Konami, 1998-present) game series to show how games are contextualised across multiple fan-websites. The final chapter contains a case study of the Sega Saturn console system to assess how fans could, in future, discover retro-games in digital environments, contrasting it with the Saturn’s presence within traditional UK museum spaces. It finds that remix practices influence a spread of retro-game digital media across networks providing numerous points of access. With the proliferation of remixed, archontic productions across digital rogue archival databases and hyperconnected websites containing contextualising documentation, fans have constructed actively transformative, retro-game cyberspaces engaged in change-directed nostalgic memory-work. The breadth of information involved in fans’ retro-game preservation (textual and extra-textual) is structured by a mediated reshaping of both the spatial and temporal qualities of retro-games, the active (re)experience of gameplay and decentralised conservation and distribution. Through reassessing fans’ emulationfocused preservation efforts by what they contribute to preservation, rather than solely inaccuracies or losses, this thesis introduces retro-game fans to the field of memory studies, and advocates for future research on their practices.

description: We investigate equilibrium statistical properties of the quantum XY spin-1/2 model in an external magnetic field when the interaction and field parts are subjected to quenched or/and annealed disorder. The randomness present in the system are termed annealed or quenched depending on the relation between two different time scales - the time scale associated with the equilibriation of the randomness and the time of observation. Within a mean-field framework, we study the effects of disorders on spontaneous magnetization, both by perturbative and numerical techniques. Our primary interest is to understand the differences between quenched and annealed cases, and also to investigate the interplay when both of them are present in a system. We observe in particular that when interaction and field terms are respectively quenched and annealed, critical temperature for the system to magnetize in the direction parallel to the applied field does not depend on any of the disorders. Further, an annealed disordered interaction neither affects the magnetizations nor the critical temperatures. We carry out a comparative study of the different combinations of the disorders in the interaction and field terms, and point out their generic features.

description: The departure from perfect spherical symmetry in the case of fullerenes, C60 being the sole exception, induces instabilities due to the stresses generated by the pentagonal protrusions in the sigma-bonded surfaces. By assuming sigma and pi separability and treating pi electrons as a degenerate Fermi gas in the two shells around the central sigma structure, the resulting degeneracy pressures can further enhance the sigma-surface initiated instabilities for non-icosahedral structures especially for those smaller than C60 as well as the icosahedral fullerenes that are larger than C60, with large protrusions. Under certain circumstances the net degeneracy pressure across the sigma surface might have structure-stabilizing effect. The role of the pi electron degeneracy in a broad range of fullerenes from C20 to C1500 and its effects on fullerene stability is investigated.

description: As many organic molecules, formic acid (HCOOH) has two conformers (trans and cis). The energy barrier to internal conversion from trans to cis is much higher than the thermal energy available in molecular clouds. Thus, only the most stable conformer (trans) is expected to exist in detectable amounts. We report the first interstellar detection of cis-HCOOH. Its presence in ultraviolet (UV) irradiated gas exclusively (the Orion Bar photodissociation region), with a low trans-to-cis abundance ratio of 2.8+-1.0, supports a photoswitching mechanism: a given conformer absorbs a stellar photon that radiatively excites the molecule to electronic states above the interconversion barrier. Subsequent fluorescent decay leaves the molecule in a different conformer form. This mechanism, which we specifically study with ab initio quantum calculations, was not considered in Space before but likely induces structural changes of a variety of interstellar molecules submitted to UV radiation.

description: Real networks exhibit heterogeneous nature with nodes playing far different roles in structure and function. To identify vital nodes is thus very significant, allowing us to control the outbreak of epidemics, to conduct advertisements for e-commercial products, to predict popular scientific publications, and so on. The vital nodes identification attracts increasing attentions from both computer science and physical societies, with algorithms ranging from simply counting the immediate neighbors to complicated machine learning and message passing approaches. In this review, we clarify the concepts and metrics, classify the problems and methods, as well as review the important progresses and describe the state of the art. Furthermore, we provide extensive empirical analyses to compare well-known methods on disparate real networks, and highlight the future directions. In despite of the emphasis on physics-rooted approaches, the unification of the language and comparison with cross-domain methods would trigger interdisciplinary solutions in the near future.

description: Mammalian offspring require parental care, at least in the form of suckling during their early development. While mothers need to invest considerable time and energy in ensuring the survival of their current offspring, they also need to optimize their investment in one batch of offspring in order to ensure future reproduction and hence lifetime reproductive success. Free-ranging dogs live in small social groups, mate promiscuously, and lack the cooperative breeding biology of other group living canids. They face high early life mortality, which in turn reduces fitness benefits of the mother from a batch of pups. We carried out a field based study on free-ranging dogs in India to understand the nature of parental care provided by mothers at different stages of pup development. Using behavioural patterns of mother-pup interactions, we draw up a timeline of pup ontogeny. Our analysis reveals that mothers cleverly reduce investment in energy intensive active care and increase passive care as the pups grow older, thereby keeping overall levels of parental care more or less constant over pup age.

description: The generation of rogue waves is investigated via a nonlocal nonlinear Schrodinger (NLS) equation. In this system, modulation instability is suppressed and is usually expected that rogue wave formation would also be limited. On the contrary, a parameter regime is identified where the instability is suppressed but nevertheless the number and amplitude of the rogue events increase, as compared to the standard NLS (which is a limit of the nonlocal system). Furthermore, the nature of these waves is investigated; while no analytical solutions are known to model these events, numerically it is shown that they differ significantly from either the rational (Peregrine) or soliton solution of the limiting NLS equation. As such, these findings may also help in rogue wave realization experimentally in these media.

description: Three Earth-sized exoplanets were recently discovered close to the habitable zone of the nearby ultracool dwarf star TRAPPIST-1. The nature of these planets has yet to be determined, since their masses remain unmeasured and no observational constraint is available for the planetary population surrounding ultracool dwarfs, of which the TRAPPIST-1 planets are the first transiting example. Theoretical predictions span the entire atmospheric range from depleted to extended hydrogen-dominated atmospheres. Here, we report a space-based measurement of the combined transmission spectrum of the two inner planets made possible by a favorable alignment resulting in their simultaneous transits on 04 May 2016. The lack of features in the combined spectrum rules out cloud-free hydrogen-dominated atmospheres for each planet at 10-$σ$ levels; TRAPPIST-1 b and c are hence unlikely to harbor an extended gas envelope as they lie in a region of parameter space where high-altitude cloud/haze formation is not expected to be significant for hydrogen-dominated atmospheres. Many denser atmospheres remain consistent with the featureless transmission spectrum---from a cloud-free water vapour atmosphere to a Venus-like atmosphere.

description: Based on the largest event sample of diffractively produced $π^-π^-π^+$, obtained by a pion beam of $190~\rm{GeV/c}$ momentum, the COMPASS collaboration has performed the most advanced partial wave analysis on multi-body final states, using the isobar model. The large number of waves included in the analysis reduces truncation effects. We have used fourteen out of a total of eighty-eight waves, to extract resonance parameters for eleven light meson candidates, most of them observed previously. The coherence of the analysis and the large variety of systematic studies has allowed to determine mass and width of most $a_{J}$ and $π_{J}$ states with six different values of $J^{PC}$ below a mass of $2.1~\rm{GeV/c^2}$, with high confidence. We exploited that the production rates of resonant and non-resonant contributions in these fourteen waves vary differently with the four-momentum transfer squared in the reaction. In addition, we have performed the first isobar-freed analysis in diffraction, from which we have determined the shape of the $[ππ]_{S-wave}$ isobar for different $J^{PC}$ of the $3π$ system.

description: We present an optically induced remanent photostriction in BiFeO3, resulting from the photovoltaic effect, which is used to modify the ferromagnetism of Ni film in a hybrid BiFeO3/Ni structure. The 75% change in coercivity in the Ni film is achieved via optical and nonvolatile control. This photoferromagnetic effect can be reversed by static or ac electric depolarization of BiFeO3. Hence, the strain dependent changes in magnetic properties are written optically, and erased electrically. Light-mediated straintronics is therefore a possible approach for low-power multistate control of magnetic elements relevant for memory and spintronic applications.

description: The evolution of a crack front under mixed mode loading (I+III) is studied using a phase field model in 3 dimensions with no stress boundary conditions. As previously observed experimentally in gels, there is a relaxation toward a geometry where $K_{III}=0$ without any front fragmentation even for high values of the initial mode mixity $K_{III}/K_{I}$. The effects of the initial condition is studied and it is shown that irregularities in the initial slit can lead to front fragmentation for smaller values of the ratio $K_{III}/K_{I}$ as is observed in experiments.

description: Two decades after the discovery of 51 Peg b, the formation processes and atmospheres of short-period gas giants remain poorly understood. Observations of eccentric systems provide key insights on those topics as they can illuminate how a planet's atmosphere responds to changes in incident flux. We report here the analysis of multi-day multi-channel photometry of the eccentric (e~ 0.93) hot Jupiter HD 80606 b obtained with the Spitzer Space Telescope. The planet's extreme eccentricity combined with the long coverage and exquisite precision of new periastron-passage observations allow us to break the degeneracy between the radiative and dynamical timescales of HD 80606 b's atmosphere and constrain its global thermal response. Our analysis reveals that the atmospheric layers probed heat rapidly (~4 hr radiative timescale) from $\lt$500 to 1400 K as they absorb ~ 20% of the incoming stellar flux during the periastron passage, while the planet's rotation period is 93$\pm_{35}^{85}$ hr, which exceeds the predicted pseudo-synchronous period (40 hr).

description: This paper presents an improved MHD modeling of the confined filament eruption in solar active region NOAA~9957 on 2002 May~27 by extending the parametric studies of the event in Torok & Kliem 2005 and Hassanin & Kliem 2016. Here the initial flux rope equilibrium is chosen to possess a small apex height identical to the observed initial filament height, which implies a more realistic inclusion of the photospheric line tying. The model matches the observations as closely as in the preceding studies, with the closest agreement again being obtained for an initial average flux rope twist of about $4π$. Thus, the model for strongly writhing confined solar eruptions, which assumes that a kink-unstable flux rope in the stability domain of the torus instability exists at the onset of the eruption's main acceleration phase, is further substantiated.

description: We report new CHARA/MIRC interferometric observations of the Cepheid archetype $δ$ Cep, which aimed at detecting the newly discovered spectroscopic companion. We reached a maximum dynamic range $ΔH $ = 6.4, 5.8, and 5.2 mag, respectively within the relative distance to the Cepheid $r < 25$ mas, $25 < r < 50$ mas and $50 < r < 100$ mas. Our observations did not show strong evidence of a companion. We have a marginal detection at $3σ$ with a flux ratio of 0.21\%, but nothing convincing as we found other possible probable locations. We ruled out the presence of companion with a spectral type earlier than F0V, A1V and B9V, respectively for the previously cited ranges $r$. From our estimated sensitivity limits and the Cepheid light curve, we derived lower-limit magnitudes in the $H$ band for this possible companion to be $H_\mathrm{comp} > 9.15, 8.31$ and 7.77 mag, respectively for $r < 25$ mas, $25 < r < 50$ mas and $50 < r < 100$ mas. We also found that to be consistent with the predicted orbital period, the companion has to be located at a projected separation $< 24$ mas with a spectral type later than a F0V star.

description: Cooperative breeding is an excellent example of altruistic cooperation in social groups. Domestic dogs have evolved from cooperatively hunting and breeding ancestors, but have adapted to a facultatively social scavenging lifestyle on streets, and solitary living in human homes. Pets typically breed and reproduce under human supervision, but free-ranging dogs can provide insights into the natural breeding biology of dogs. We conducted a five year long study on parental care of free-ranging dogs in India. We observed widespread alloparenting by both adult males and females. Allomothers provided significantly less care that the mothers, but the putative fathers showed comparable levels of care with the mothers. However, the nature of care varied; mothers invested more effort in feeding and allogrooming, while the putative fathers played and protected more. We were unsure of the relatedness of the pups with the putative fathers, but all the allomothers were maternal relatives of the pups, which provides support for both the benefit-of-philopatry and assured fitness returns hypotheses. Free-ranging dogs are not cooperative breeders like wolves, but are more similar to communal breeders. Their breeding biology bears interesting similarities with the human joint family system.

description: There are growing number of empirical studies on the baobab value chain in Sub-Saharan Africa. Most studies focus on nutritional composition, traditional uses, the distribution of baobab trees, and collection. However, there are few studies on the marketing of baobab fruit pulp, especially on consumer behavior, attitudes, and beliefs regarding baobab fruit pulp. In this context, our study aims to explore consumer behavior, attitudes and beliefs regarding baobab fruit pulp. We also evaluate the market development potential of baobab fruit pulp in selected markets in El Obeid and Khartoum in Sudan. The study employs a mixed methods approach that includes a survey (N = 499), focus group discussion (N = 16), stakeholder interviews (N = 2), and a SWOT analysis. The study shows that the consumption of baobab fruit pulp is common among Sudanese consumers. Consumers also show strong positive attitudes and beliefs, as well as social support for baobab consumption. Nutritional and health benefits tend to drive consumer interest in baobab fruit pulp. The study also identified high demand, export opportunities, and extraction of ingredients from baobab as opportunities to develop baobab markets. However, a lack of quality control, regulations, poor distribution, and insufficient fruit supply may limit exploration of these opportunities. Therefore, it is crucial to raise knowledge of the nutritional and functional properties of baobab fruit, as well as its ability to fight health-related diseases, to further develop local markets.

description: We theoretically investigate the many-body localization phase transition in a one-dimensional Ising spin chain with random long-range spin-spin interactions, $V_{ij}\propto\left|i-j\right|^{-α}$, where the exponent of the interaction range $α$ can be tuned from zero to infinitely large. By using exact diagonalization, we calculate the half-chain entanglement entropy and the energy spectral statistics and use them to characterize the phase transition towards the many-body localization phase at infinite temperature and at sufficiently large disorder strength. We perform finite-size scaling to extract the critical disorder strength and the critical exponent of the divergent localization length. With increasing $α$, the critical exponent experiences a sharp increase at about $α=1$ and then gradually decreases to a value found earlier in a disordered short-ranged interacting spin chain. For $α<1$, we find that the system is mostly localized and the increase in the disorder strength may drive a transition between two many-body localized phases. In contrast, for $α>1$, the transition is from a thermalized phase to the many-body localization phase. Our predictions could be experimentally tested with ion-trap quantum emulator with programmable random long-range interactions, or with randomly distributed Rydberg atoms or polar molecules in lattices.

description: Nel 1964, all’Esposizione Universale di New York, una sala era dedicata interamente alla matematica e ai matematici. Un enorme pannello che ne descriveva i progressi dal 1000 A.C. fino a quel momento, era intitolato: Uomini della matematica. Alle pareti più di ottanta ritratti di matematici, tutti uomini, eccetto lei: Emmy Nöther. Tutte le biografie, tra cui quella scritta da un’altra donna matematica, Auguste Franziska Dick, nel 1970,la descrivono come: una donna poco attraente e sebbene il suo viso non fosse piacevole, mostrava intelligenza e poteva suggerire il suo amore per la scienza. Perfino, Francesco Severi, un collega toscano con cui ballava -una passione che Emmy coltivava sin da giovane- il 9 settembre 1932, a Zurigo, durante il IX Congresso internazionale dei matematici, la giudicava "scarsamente dotata di attrattive femminili; figura piccola e tozza". Emmy Nöther non sembrava curarsene e ballava soddisfatta: in quel congresso, soltanto pochi giorni prima, il 7, aveva tenuto una conferenza plenaria a sezioni riunite - Le algebre e le loro applicazioni all'algebra commutativa e alla teoria dei numeri- forse il massimo riconoscimento ufficiale che avesse mai ricevuto, una vera consacrazione. Mi ha sempre sorpreso la spasmodica attenzione all’aspetto fisico di una scienziata, come a ricercare la motivazione nascosta che spinge una donna a dedicarsi ad altro che non alla famiglia. Non ho mai ritrovato osservazioni del genere riguardo a uomini scienziati. Intorno alle scienziate si concentra una lunga serie di luoghi comuni difficili da archiviare. Per Emmy la vita è stata ancora più straordinaria, al di là dei luoghi comuni.

description: In this work, a new prototype-based clustering method named Evidential C-Medoids (ECMdd), which belongs to the family of medoid-based clustering for proximity data, is proposed as an extension of Fuzzy C-Medoids (FCMdd) on the theoretical framework of belief functions. In the application of FCMdd and original ECMdd, a single medoid (prototype), which is supposed to belong to the object set, is utilized to represent one class. For the sake of clarity, this kind of ECMdd using a single medoid is denoted by sECMdd. In real clustering applications, using only one pattern to capture or interpret a class may not adequately model different types of group structure and hence limits the clustering performance. In order to address this problem, a variation of ECMdd using multiple weighted medoids, denoted by wECMdd, is presented. Unlike sECMdd, in wECMdd objects in each cluster carry various weights describing their degree of representativeness for that class. This mechanism enables each class to be represented by more than one object. Experimental results in synthetic and real data sets clearly demonstrate the superiority of sECMdd and wECMdd. Moreover, the clustering results by wECMdd can provide richer information for the inner structure of the detected classes with the help of prototype weights.
A Model to Estimate First-Order Mutation Coverage from Higher-Order Mutation Coverage

description: The test suite is essential for fault detection during software development. First-order mutation coverage is an accurate metric to quantify the quality of the test suite. However, it is computationally expensive. Hence, the adoption of this metric is limited. In this study, we address this issue by proposing a realistic model able to estimate first-order mutation coverage using only higher-order mutation coverage. Our study shows how the estimation evolves along with the order of mutation. We validate the model with an empirical study based on 17 open-source projects.

description: One difficulty faced in knowledge engineering for Bayesian Network (BN) is the quan-tification step where the Conditional Probability Tables (CPTs) are determined. The number of parameters included in CPTs increases exponentially with the number of parent variables. The most common solution is the application of the so-called canonical gates. The Noisy-OR (NOR) gate, which takes advantage of the independence of causal interactions, provides a logarithmic reduction of the number of parameters required to specify a CPT. In this paper, an extension of NOR model based on the theory of belief functions, named Belief Noisy-OR (BNOR), is proposed. BNOR is capable of dealing with both aleatory and epistemic uncertainty of the network. Compared with NOR, more rich information which is of great value for making decisions can be got when the available knowledge is uncertain. Specially, when there is no epistemic uncertainty, BNOR degrades into NOR. Additionally, different structures of BNOR are presented in this paper in order to meet various needs of engineers. The application of BNOR model on the reliability evaluation problem of networked systems demonstrates its effectiveness.

description: In this article, using an infinite-dimensional equivariant Conley index, we prove a generalization of the profitable Liapunov center theorem for symmetric potentials. Consider the system $\ddot{q}= -\nabla U(q),$ where $U(q)$ is a $Γ$-symmetric potential, where $Γ$ is a compact Lie group acting linearly on $\mathbb{R}^n$. If the system possess a non-degenerate orbit of stationary solutions $Γ(q_0)$ with trivial isotropy group, such that there exists at least one positive eigenvalue of the Hessian $\nabla^2 U(q_0)$, then in any neighbourhood of orbit $Γ(q_0)$ there is a periodic orbit of solutions of the system.

description: The small mass and high coherence of nanomechanical resonators render them the ultimate force probe, with applications ranging from biosensing and magnetic resonance force microscopy, to quantum optomechanics. A notorious challenge in these experiments is thermomechanical noise related to dissipation through internal or external loss channels. Here, we introduce a novel approach to defining nanomechanical modes, which simultaneously provides strong spatial confinement, full isolation from the substrate, and dilution of the resonator material's intrinsic dissipation by five orders of magnitude. It is based on a phononic bandgap structure that localises the mode, without imposing the boundary conditions of a rigid clamp. The reduced curvature in the highly tensioned silicon nitride resonator enables mechanical $Q>10^{8}$ at $ 1 \,\mathrm{MHz}$, yielding the highest mechanical $Qf$-products ($>10^{14}\,\mathrm{Hz}$) yet reported at room temperature. The corresponding coherence times approach those of optically trapped dielectric particles. Extrapolation to $4{.}2$ Kelvin predicts $\sim$quanta/ms heating rates, similar to trapped ions.

Stellar populations, and observation cosmology with Roman and JWST

description: Globular clusters are an excellent probe to investigate the distribution of dark matter from small to large scale and the assembly history of galaxy clusters and groups. There are two types of globular clusters depending on their location: galaxy globular clusters, and intergalactic globular clusters (intracluster or intragroup GCs, called IGCs). The JWST opened a new era in the study of globular clusters in galaxy clusters, exceeding the limit of the HST. The JWST/NIRCam images of a massive galaxy cluster SMACS 0723 at z=0.39 show not only a rich population of IGCs, but also gravitationally-lensed younger globular clusters in high-z galaxies behind the SMACS 0723. While the IGCs tell us the distribution of dark matter and how the cluster is assembled, the globular clusters at low to high redshift provide the time series snapshots of massive star clusters at different evolutionary phases, enabling us to understand how globular clusters evolve. Roman is an ideal telescope to study globular clusters in nearby large galaxy clusters and groups as well as resolved stars in nearby large galaxies. I will discuss how our current understanding of these globular clusters as well as resolved stars will be transformed with Roman.

description: This study examined the relationship between return on equity for individual Kansas farms and the S&P 500 using data from 1996 to 2018. Return on equity was measured with and without the inclusion of capital gains on land. Results indicated that return on equity with capital gains on land adjusted for risk was 1.2 percent above S&P returns during the period. For most of the farms in the sample, the risk faced by individual farms was not related to risk incorporated into the S&P 500 index, suggesting that there are opportunities for farm operations to diversify their risk by investing in the stock market.
