description: We outline a modeling and optimization strategy for investigating dynamic metabolic engineering interventions. Our framework is particularly useful at the early stages of research and development, often constrained by limited knowledge and experimental data. Elucidating a priori optimal trajectories of manipulatable intracellular fluxes can guide the design of suitable control schemes, e.g., cyber(ge)netic or in-cell approaches, and the selection of appropriate actuators, e.g., at the transcriptional or post-translational levels. Model-based dynamic optimization is proposed to predict optimal trajectories of target manipulatable intracellular fluxes. A challenge emerges as existing models are often oversimplified, lacking insights into metabolism, or excessively complex, making them difficult to build and implement. Here, we use surrogates derived from steady-state solutions of constraint-based metabolic models to link manipulatable intracellular fluxes to the process exchange rates of structurally simple hybrid dynamic models. The latter can be conveniently used in optimal control problems of metabolism. As a proof of concept, we apply our method to a reduced metabolic network of $\textit{Escherichia coli}$ considering two different scenarios of dynamic metabolic engineering.

Students' Perceptions of Women in Management: 1988-2018
Creators: name: Frank, Ellen
Publisher: name: Advancing Women in Leadership Journal
Year: 2022

description: Replicates a study completed 30-years before regarding college students' perceptions of women in management. Questions include descriptions on semantic differential scales of male/female managers, personal preferences for a boss, and estimates on when management equality would be achieved by women. Factor analysis in 2018 defined the same three factors as in 1988. Male managers' factor scores are higher on "Managerial Behavior," female managers higher on "Consideration," and no significant difference for "Initiation of Structure" in both studies. When asked the preferred boss of a mixed-gender group, women are more likely to select a man, although this preference has decreased. There was a significant increase for females to choose a woman manager as their personal boss preference. Results indicate little change in the stereotypical description of a woman manager, and that current female students have the "Think manager - Think male" attitude. There is also the perception that in the population at-large, it is not yet acceptable for women to pursue a managerial career when married with children. However, men have significantly increased their personal acceptance of career women. Keywords: woman in management, college student, perception of managers

Subjects: Economics

description: In spite of the growth of many higher education institutes in Bangladesh over the last two decades, there exists a skills gap, which has resulted in a significant fraction of the educated workforce being unemployed. This paper aims at exploring the reasons behind this problem. Deficiencies in the education system, absence of soft and specialized skills among graduates, underestimation of the role of TVET, improper planning by policy makers and many more reasons have been presented as key contributors to skills gap. In the light of the findings presented in the study, an attempt has been made to outline the major implications for policy. Collaboration of higher education institutes, employers and policy makers has been suggested as the way forward. To name a few, pairing of industry with local institutes, analysis of demand and supply of skilled labor and a mechanism to address the gap between demand and supply have been discussed.

description: We report the serendipitous discovery of an elliptical shell of CO associated with the faint stellar object SSTc2d J163134.1-24006 as part of the "Ophiuchus Disk Survey Employing ALMA" (ODISEA), a project aiming to study the entire population of protoplanetary disks in the Ophiuchus Molecular Cloud from 230 GHz continuum emission and $^{12}$CO (J=2-1), $^{13}$CO (J=2-1) and C$^{18}$CO (J=2-1) lines readable in Band-6. Remarkably, we detect a bright $^{12}$CO elliptical shape emission of $\sim$ 3$^{"}$ $\times$ 4$^{"}$ towards SSTc2d J163134.1-24006 without a 230 GHz continuum detection. Based on the observed near-IR spectrum taken with the Very Large Telescope (KMOS), the brightness of the source, its 3-dimensional motion, and Galactic dynamic arguments, we conclude that the source is not a giant star in the distant background ($>$5 - 10 kpc) and is most likely to be a young brown dwarf in the Ophiuchus cloud, at a distance of just $\sim$139 pc. This is the first report of quasi-spherical mass loss in a young brown dwarf. We suggest that the observed shell could be associated with a thermal pulse produced by the fusion of deuterium, which is not yet well understood, but for a sub-stellar object is expected to occur during a short period of time at an age of a few Myr, in agreement with the ages of the objects in the region. Other more exotic scenarios, such as a merger with planetary companions, cannot be ruled out from the current observations.

Density-functional study of Cu atoms, monolayers, and coadsorbates on polar ZnO surfaces

description: The structure and electronic properties of single Cu atoms, copper monolayers and thin copper films on the polar oxygen and zinc terminated surfaces of ZnO are studied using periodic density-functional calculations. We find that the binding energy of Cu atoms sensitively depends on how charge neutrality of the polar surfaces is achieved. Bonding is very strong if the surfaces are stabilized by an electronic mechanism which leads to partially filled surface bands. As soon as the surface bands are filled (either by partial Cu coverage, by coadsorbates, or by the formation of defects), the binding energy decreases significantly. In this case, values very similar to those found for nonpolar surfaces and for copper on finite ZnO clusters are obtained. Possible implications of these observations concerning the growth mode of copper on polar ZnO surfaces and their importance in catalysis are discussed.

description: One of the most pressing problems in the development of domestic agriculture is the significant weeding of crops, including soybeans. Soil and climatic conditions of Ukraine mainly contribute to the cultivation of this crop. At the beginning of the growing season, soybeans grow relatively slowly, and weeds compete with them for moisture, nutrients, light use, and so on. This results in low crop competitiveness compared to weeds. Yield losses from weeds can average 30 to 50%, and sometimes they can die completely. To control weeds in soybean crops should use soil herbicide Frontier® Optima k.e., 1,0 l/ha + in phase 5 trifoliate soybean leaves post-emergence herbicide Korum p. K., 1,5 l/ha + South Africa Metholate, 1,0 l/ha + in the phase of the beginning of soybean budding foliar application of the microfertilizer Quantum Molybdenum Chelate (Mo), 0,5 l/ha, as a result of which it is possible to obtain soybean seed yield at the level of 2,94 t/ha.

description: Context. After landing on C-type asteroid Ryugu, MASCOT imaged brightly colored, submillimeter-sized inclusions in a small rock. Hayabusa2 successfully returned a sample of small particles from the surface of Ryugu, but none of these appear to harbor such inclusions. The samples are considered representative of Ryugu. Aims. To understand the apparent discrepancy between MASCOT observations and Ryugu samples, we assess whether the MASCOT landing site, and the rock by implication, is perhaps atypical for Ryugu. Methods. We analyzed observations of the MASCOT landing area acquired by three instruments on board Hayabusa2: a camera (ONC), a near-infrared spectrometer (NIRS3), and a thermal infrared imager (TIR). We compared the landing area properties thus retrieved with those of the average Ryugu surface. Results. We selected several areas and landforms in the landing area for analysis: a small crater, a collection of smooth rocks, and the landing site itself. The crater is relatively blue and the rocks are relatively red. The spectral and thermophysical properties of the landing site are very close to those of the average Ryugu surface. The spectral properties of the MASCOT rock are probably close to average, but its thermal inertia may be somewhat higher. Conclusions. The MASCOT rock can also be considered representative of Ryugu. Some of the submillimeter-sized particles in the returned samples stand out because of their atypical spectral properties. Such particles may be present as inclusions in the MASCOT rock.

description: In this study, we demonstrate a novel self-navigated motion correction method that suppresses eye motion and blinking artifacts on wide-field optical coherence tomographic angiography (OCTA) without requiring any hardware modification. Highly efficient GPU-based, real-time OCTA image acquisition and processing software was developed to detect eye motion artifacts. The algorithm includes an instantaneous motion index that evaluates the strength of motion artifact on en face OCTA images. Areas with suprathreshold motion and eye blinking artifacts are automatically rescanned in real-time. Both healthy eyes and eyes with diabetic retinopathy were imaged, and the self-navigated motion correction performance was demonstrated.

description: The problem of nature protection for Vinnytsia region, most of the territory of which is experiencing almost uncontrolled intensive economic activity, is very relevant. Natural conditions and resources of Vinnytsia are diverse and unique, today the question of their rational use is still insufficiently studied. Preservation of modern nature, increasing its wealth, is impossible without a detailed knowledge of history. It is the knowledge of the past that helps us to better understand the present and predict the future state of nature of the region, the possibility of its reconstruction not only by preserving but also creating new environmental facilities. Modern development of human activity is often harmful to the environment due to the growth of urban planning, industrial production, traffic. Therefore, there is pollution of water, air, soil, which negatively affects the health of the population, poses a threat to the environment, exacerbates environmental problems.
Reflections on engagement with a First Nation elder : four lessons for Canadian teachers beginning their careers in northern Canadian First Nation communities
Creators: name: McDonnell, Robert
Publisher: name: The University of British Columbia
Year: 2012

description: Many provincially licensed teachers with degrees from southern Canadian universities are hired to teach in Northern Canadian First Nation communities each year. In fact, the year I was hired to teach in a small, First Nation community in central Yukon, there were four other new teachers moving up from cities in the south. Yukon Government's website states, "teachers who wish to apply to teach in one of the Yukon's 29 schools must hold or be eligible for certification in a Canadian province" (YE, 2011). I quickly learned that being a non-First Nation teacher in a First Nation community is very challenging. After three years, I chose to leave and accept a teaching position in the capital city, where the vast majority of students were non-First Nation and had been brought up in the city. I left the village feeling disengaged from the people of the community and professionally deflated. I am unsure if I provided anything of lasting value to my students. Years later, through a process of further education and reflection on my past experience, I have learned several lessons about what non-First Nation, beginning teachers ought to understand, so they may appropriately engage with the local community and with their students. In the article that follows, I share the following four lessons: 1) Reach out to those in the community, and remain a learner, open to community knowledge, 2) facilitate authentic experiences for students, 3) facilitate the teaching of traditional community skills to assist students’ spiritual development, and 4) bring the school and community together to create culturally relevant education. My hope is that other teachers traveling north to teach in Canadian First Nation communities may learn from my experience and be positioned to create more positive relationships and meaningful learning opportunities.

description: We prove the concavity of classical solutions to a wide class of degenerate elliptic differential equations on strictly convex domains of the unit sphere. The proof employs a suitable two-point maximum principle, a technique which originates in works of Korevaar, Kawohl and Kennington for equations on Euclidean domains. We emphasize that no differentiability of the differential operator is needed, but only some monotonicity and concavity properties.

description: Effects of randomness on non-integer power law tails in multiplicatively interacting stochastic processes are investigated theoretically. Generally, randomness causes decrease of the exponent of tails and the growth rate of processes. Explicit calculations are performed for two examples: uniformly distributed and two peaked systems. Significant influence is demonstrated when a bare growth rate is low and coupling is weak. It should be emphasized that even the sign of the growth rate can be changed from positive to negative growth.

description: Under nonuniform convection, the distribution of diffusive particles can exhibit dipole and quadrupole anisotropy induced by the fluid inertial and shear force, respectively. These convection-related anisotropies, unlike the Compton-Getting effect, typically increase with the cosmic-ray (CR) energy, and are thus candidate contributors for the CR anisotropy. In consideration of the inertial effect, CR observational data can be used to set an upper limit on the average acceleration of the local interstellar medium in the equatorial plane to be on the order of 100 $ μ\text{m}/\text{s}^2 $. Using Oort constants, the quadrupole anisotropy above 200 TeV may be modeled with the shear effect arising from the Galactic differential rotation.

description: Molecular clouds are sites of star formation. Magnetic fields are believed to play an important role in their dynamics and shaping morphology. We aim to study any possible correlation that might exist between the magnetic fields orientation inside the clouds and the magnetic fields at envelope scales and their connection with respect to the observed morphology of the selected clouds. We examine the magnetic field orientation towards the clouds L1512, L1523, L1333, L1521E, L1544, L1517, L1780, and L183 using optical and \textit{Planck} polarization observations. We also found the correlation between the ambient magnetic field and core orientations derived using \textit{Astrodendrogram} on the \textit{Herschel} 250 $μ$m data. We find that the magnetic fields derived from optical and \textit{Planck} agree with each other. The derived magnetic fields are aligned along the observed emission of each cloud as seen in \textit{Herschel} 250 $μ$m data. We also find that the relative orientation between the cores and the magnetic fields is random. This lack of correlation may arise due to the fact that the core orientation could also be influenced by the different magnetization within individual clouds at higher densities or the feedback effects which may vary from cloud to cloud. The estimated magnetic field strength and the mass-to-flux ratio suggest that all the clouds are in a magnetically critical state except L1333, L1521E, and L183 where the cloud envelope could be strongly supported by the magnetic field lines.

description: This thesis will describe attempts to use suitably substituted 2-imidazolines in Diels-Alder reactions. In order to synthesise these target 2-imidazolines a new and reliable method for the synthesis of 2-alkyl and 2-alkenyl-2-imidazolines has been developed. Metallation at C(2a) of l-ferf-butyloxycarbonyl-2-methyl-2-imidazoline, followed by reaction with a range of electrophiles and deprotection with TFA reliably afforded N(l)- unsubstituted 2-substituted 2-imidazolines; P- or Se-electrophiles led to 2-alkenyl-2- imidazolines via Wadsworth-Emmons reaction or selenoxide elimination.

In an attempt to prepare N-butadienyl-2-imidazolines via the reaction of 2-alkyl-2-imidazolines and ɑ,ß-unsaturated aldehydes or ketones, tetrahydroimidazo[1,2-a]pyridines have been synthesised via conjugate addition of the heterocycle N(l) nitrogen atom followed by enamine-aldol condensation at C(2ɑ).

 2-Imidazolines reacted with ß-ketoesters to give tetrahydroimidazo[1,2-a]pyridin- 5-ones.

 Whilst examining the reactions of 2-alkyl-2-imidazolines with alkyne diesters, a new annulation was uncovered that is based on N(l) conjugate addition followed by C(2ɑ) The reaction of 2-imidazolines with dialkyl acetylenedicafboxylate afforded tetrahydropyrrolo[1,2-a]imidazole-5,6-diones.

 None of the 2-imidazolines synthesised that contained diene functionalities underwent either intra or intermolecular Diels-Alder reactions.

description: The constraints arising from anomaly cancellation are particular strong for chiral theories in six dimensions. We make progress towards a complete classification of 6D supergravities with minimal supersymmetry and non-abelian gauge group. First, we generalize a previously known infinite class of anomaly-free theories which has $T\gg 9$ to essentially any semi-simple gauge group and infinitely many choices for hypermultiplets. The construction relies on having many decoupled sectors all selected from a list of four simple theories which we identify. Second, we use ideas from graph theory to rephrase the task of finding anomaly-free theories as constructing cliques in a certain multigraph. A branch-and-bound type algorithm is described which can be used to explicitly construct, in a $T$-independent way, anomaly-free theories with an arbitrary number of simple factors in the gauge group. We implement these ideas to generate an ensemble of $\mathcal{O}(10^7)$ irreducible cliques from which anomaly-free theories may be easily built, and as a special case obtain a complete list of $19,\!847$ consistent theories for $T=0$, for which the maximal gauge group rank is $24$. Modulo $\mathrm{U}(1)$, $\mathrm{SU}(2)$ and $\mathrm{SU}(3)$ simple factors and the new infinite families, we give a complete characterization of anomaly-free theories and show that the bound $T\leq 273$ is sharp.

title: Conflicts among lesbian representations in Hungary
Creators: name: Kalocsai, Csilla
Publisher: name: The Open University
Year: 2000

description: In this study I examine dominant representations of lesbians and lesbian self-representations on identity and community in Hungary. I situate my study within the current political-economic transition, which provides the temporal scope of this project. I argue that the breakdown of state-socialism in Hungary offered opportunity for the establishment of civil society and the introduction of gay and feminist civil organizations. I consider gay and feminist organizations as subaltern counterpublics that provide space for lesbians to enter and account for the emergence and circulation of lesbian representations. I explore how the Hungarian popular media depicts lesbians. I focus on the representational practices of the media texts, and I argue that Hungarian media constructs lesbianism in an ambivalent way. The journalistic representations give occasional visibility to lesbians, however, they restrict lesbian's voices, produce and reproduce stereotypical images about lesbians. The framing of the texts explicitly or implicitly mobilize dominant discourses on lesbianism, they thus reinscribe lesbianism into mainstream discourses. Lesbian self-representations overlap and at times conflict with dominant representations of lesbians. In my empirical study, I investigate how lesbians represent and construct their identities in coming-out narratives. I show that the women interviewed present their identity as original, continuous, and totalizing. The adherence to essentialism makes coming out possible in a context which denies to recognize lesbian difference. Lesbian self-representations reproduce dominant representations of lesbians by laying claim to essentialist conceptions of identity, but they also contest mainstream representations by pointing out the social conditions of the construction of lesbian identity. I also show how lesbians represent and construct their communities in their narratives. I argue that lesbians search for communities that are predicated on their shared sexual and gender identity and on their common experience of heterosexist and patriarchal oppression. However, I also point out that lesbian communities are multiple and fragmented social arenas which are constituted by differences and conflicts among lesbians. The inquiry of lesbian communities interrogates dominant representations by articulating lesbian political participation and questions lesbian self-representations of identity by reflecting on the differences among lesbian identities.

description: As reserve talents for research, graduate students of scientific research institutions directly participate in the implementation process of various scientific research projects, which greatly promotes the innovation work of scientific research institutions. As an essential part of the national agricultural scientific and technological innovation system, provincial agricultural research institutions urgently need to maintain or expand the team of graduate students. Under the current graduate student recruitment system, provincial agricultural research institutions need to solve the problem of how to innovate on the recruitment methods, continuously expand the recruitment scale, and attract more outstanding graduate students to join the scientific and technological innovation team. This paper firstly introduced the institutional changes and recruitment status of graduate students in agricultural research institutions, then analyzed the problems faced by provincial agricultural research institutions in recruiting graduate students. Finally, combining the work practice of Jiangsu Academy of Agricultural Sciences, it came up with pertinent recommendations, to provide references for graduate student recruitment of provincial agricultural research institutions.

description: Today we can say that amaranth is a valuable fodder, food and medicinal plant, the green mass of which can be used in livestock production both in fresh form and for the preparation of silage and protein-vitamin concentrate. In terms of amino acid balance, green mass of amaranth is of the same quality as alfalfa, but compared with other legumes has a higher lysine content. For pigs, the protein of green mass of amaranth is close to the ideal. Amaranth seeds have high nutritional value and contain oil, which has bactericidal activity and anticancer effect. Compared to other agricultural plants, amaranth spends two to three times less water to form a unit of organic matter. However, the introduction of amaranth into culture in Ukraine requires determining its appropriate place in the structure of fodder and food resources, justification of agroecological and technological bases of cultivation, identification of species with high adaptive potential and high ability to realize productivity, creation of varieties of appropriate directions of use, development of cultivation technology. No less important is the economic efficiency of amaranth production.

description: Assessment of bioenergy potential of rice varieties showed that by-products (straw and husk) of Vikont and Premium demonstrate the highest values of energy output; these varieties were studied to establish how the agronomic factors affect the formation of rice productivity with the final products meant for food and straw and husk being a source of bioenergy plant material as a solid biofuel. In field experiments the biggest yields of rice were obtained under applied mineral fertilizers N180P60K0 with seeding rate of 9 million of similar seeds per hectare for Vikont and Premium varieties at the levels of 9 and 8 t/ha, respectively. Thus, the optimal combination of rice farming techniques leads to high yields of the crop, and at the same time, to significant amounts of by-products suitable for further use. The results of the study showed that rice straw should be used as a source of alternative energy, ricegrowing regions of Ukraine could get heat energy equivalent to the amount released during combustion of 62 million m3 of gas. The economic effect of the transition from gas heat generators to the biomass heat generators leads to annual cost cutout of USD 192.3 thousand, and the payback period is 1.14 year. An additional source of alternative energy is the rice husk; the payback of launching a rice husk briquetting line is 1.6 year.

description: We investigate cosmological dynamics of multiple tachyon fields with inverse square potentials. A phase-space analysis of the spatially flat FRW models shows that there exists power-law cosmological scaling solutions. We study the stability of the solutions and find that the potential-kinetic-scaling solution is a global attractor. However, in the presence of a barotropic fluid the solution is an attractor only in one region of the parameter space and the tracking solution is an attractor in the other region. We briefly discuss the physical consequences of these results.

description: We investigate the influence of quasiperiodic modulations on one-dimensional non-Hermitian diamond lattices with an artificial magnetic flux $θ$ that possess flat bands. Our study shows that the symmetry of these modulations and the magnetic flux $θ$ play a pivotal role in shaping the localization properties of the system. When $θ=0$, the non-Hermitian lattice exhibits a single flat band in the crystalline case, and symmetric as well as antisymmetric modulations can induce accurate mobility edges. In contrast, when $θ=π$, the clean diamond lattice manifests three dispersionless bands referred to as an "all-band-flat" (ABF) structure, irrespective of the non-Hermitian parameter. The ABF structure restricts the transition from delocalized to localized states, as all states remain localized for any finite symmetric modulation. Our numerical calculations further unveil that the ABF system subjected to antisymmetric modulations exhibits multifractal-to-localized edges. Multifractal states are predominantly concentrated in the internal region of the spectrum. Additionally, we explore the case where $θ$ lies within the range of $(0, π)$, revealing a diverse array of complex localization features. Finally, we propose a classical electrical circuit scheme to realize the non-Hermitian flat-band chain with quasiperiodic modulations.

description: This study uses survey data to analyze the association between restaurant menu label use and total and source-specific daily caloric intakes among U.S. adults age 20 and older who saw nutrition information on a menu the last time they visited a fast-food or sit-down restaurant. Findings show that survey respondents who report seeing and using restaurant menu labels consume significantly fewer total calories per day than do respondents who report seeing the labels but not using them. Fast-food and sit-down restaurant menu label uses are both significantly associated with lower total daily caloric intake, and the associations are estimated to be of similar magnitudes. Findings also suggest that the total daily calorie consumption difference between restaurant menu label users and nonusers may be partly attributable to restaurant menu label users’ lower intake of calories from restaurants that post nutrition information on menus. Taken together, these results suggest that nutrition information on restaurant menus may be helping some consumers to align their food orders according to their demand for lower calories which, in turn, is also helping them to keep their total daily caloric intake lower relative to consumers who see but do not use the information.

title: Ilma: Meanings of Hysteria and the Beginnings of Hungarian Psychiatry.
Creators: name: Lafferton, Emese
Publisher: name: The Open University
Year: 1999

description: The dissertation reconstructs the life of Ilma Szekulics, an intelligent middle-class woman raised in a convent, who rebelled against the confines imposed on her by her sex, her family and society, and who employed deviant forms of social behaviour to survive. A petty thief, a forger, and a cross-dresser, she became the number one patient of top psychiatrists in Austro-Hungary in the 1880s, diagnosed as suffering from hystero-epilepsy and 'contrary sexual feelings'. Her story helps understand and fit the figure of the hysterical woman both into the context of late-nineteenth-century psychiatric knowledge, and into general thinking on female nature and body, sexuality, lesbianism, and cross-dressing.
 Ilma's well-documented case (her autobiographical writings, studies by her Hungarian doctors, a 130-page long book by Krafft-Ebing, and articles in the daily press) allows an approach to hysteria and hypnosis "from inside" that is, through the actual encounters between doctor and patient. Questions of their co-operation as well as their personal strategies, desires, and aspirations occupy centre stage. From such an approach, hysteria and hypnosis emerges as a "process" exposed to ongoing negotiation, rather than as a final set of characteristics.
 Focus on the patient and the inner dynamics of the doctor-patient encounters opens the way for a subversive reading of the power relations in the medical setting. Medical knowledge, its institutional framework and practice embodied and reinforced the power relations between man and woman, doctor and patient. At the same time, an awareness of social constraints and possibilities, if cleverly exploited, could open up some space for manoeuvring and negotiations. Ilma’s case shows how social constraints and private interests combine into various forms of self-fashioning.
Photon velocity, power spectrum in Unruh effect with modified dispersion relation

description: In this paper we propose a new form of generalized uncertainty principle which involves both a linear as well as a quadratic term in the momentum. From this we have obtained the corresponding modified dispersion relation which is compared with the corresponding relation in rainbow gravity. The new form of the generalized uncertainty principle reduces to the known forms in appropriate limits. We then calculate the modified velocity of photons and we find that it is energy dependent, allowing therefore for a superluminal propagation. We then derive the $1+1$-dimensional Klein-Gordon equation taking into account the effects of the modified dispersion relation. The positive frequency mode solution of this equation is then used to calculate the power spectrum arising due to the Unruh effect. The result shows that the power spectrum depends on the energy of the particle owing its origin to the presence of the generalized uncertainty principle. Our results capture the effects of both the simplest form as well as the linear form of the generalized uncertainty principle and also points out an error in the result of the power spectrum up to first order in the generalized uncertainty principle parameter existing in the literature.

description: Studying the effect of high pressure (exceeding 10 kbar) on the structure of solids allows to gain deeper insight in the mechanism governing crystal structure stability. Here we report a study on the high-pressure behaviour of zinc difluoride (ZnF2) - an archetypical ionic compound which at ambient pressure adopts the rutile (TiO2) structure. Previous investigations, limited to a pressure of 15 GPa, revealed that this compound undergoes two pressure-induced phase transitions: TiO2 - CaCl2 at 4.5 GPa, and CaCl2 - HP-PdF2 at 10 GPa. Within this joint experimental-theoretical study we extend the room temperature phase diagram of ZnF2 up to 55 GPa. By means of Raman spectroscopy measurements we identify two new phase transitions: HP-PdF2 - HP1-AgF2 at 30 GPa and HP1 AgF2 - PbCl2 at 44 GPa. These results are confirmed by Density Functional Theory calculations which indicate that in the HP1-AgF2 polymorph the coordination sphere of Zn2+ undergoes drastic changes upon compression. Our results point to important differences in the high-pressure behaviour of ZnF2 and MgF2, despite the fact that both compounds contain cations of similar size. We also argue that the HP1-AgF2 structure, previously observed only for AgF2, might be observed at large compression in other AB2 compounds.

description: We survey results on the creation of heteronuclear Fermi molecules by tuning a degenerate Bose-Fermi mixture into the neighborhood of an association resonance, either photoassociation or Feshbach, as well as the subsequent prospects for Cooper-like pairing between atoms and molecules. In the simplest case of only one molecular state, corresponding to either a Feshbach resonance or one-color photoassociation, the system displays Rabi oscillations and rapid adiabatic passage between a Bose-Fermi mixture of atoms and fermionic molecules. For two-color photoassociation, the system admits stimulated Raman adiabatic passage (STIRAP) from a Bose-Fermi mixture of atoms to stable Fermi molecules, even in the presence of particle-particle interactions. By tailoring the STIRAP sequence it is possible to deliberately convert only a fraction of the initial atoms, leaving a finite fraction of bosons behind to induce atom-molecule Cooper pairing via density fluctuations; unfortunately, this enhancement is insufficient to achieve a superfluid transition with present ultracold technology. We therefore propose the use of an association resonance that converts atoms and diatomic molecules (dimers) into triatomic molecules (trimers), which leads to a crossover from a Bose-Einstein condensate of trimers to atom-dimer Cooper pairs. Because heteronuclear dimers may possess a permanent electric dipole moment, this overall system presents an opportunity to investigate novel microscopic physics.
