description: The abundance patterns of $r$-process-enhanced stars contain key information required to constrain the astrophysical site(s) of $r$-process nucleosynthesis, and to deepen our understanding of the chemical evolution of our Galaxy. In order to expand the sample of known $r$-process-enhanced stars, we have developed a method to search for candidates in the LAMOST medium-resolution ($R \sim 7500$) spectroscopic survey by matching the observed spectra to synthetic templates around the Eu II line at 6645.1 AA. We obtain a sample of 13 metal-poor ($-2.35

description: We present a logical separability analysis for a functional quantum computation language. This logic is inspired by previous works on logical analysis of aliasing for imperative functional programs. Both analyses share similarities notably because they are highly non-compositional. Quantum setting is harder to deal with since it introduces non determinism and thus considerably modifies semantics and validity of logical assertions. This logic is the first proposal of entanglement/separability analysis dealing with a functional quantum programming language with higher-order functions.

description: Properties of six-quark dibaryons in nuclear medium are considered by example of $A=6$ nuclei within the three-cluster $α+2N$ model. Dibaryon production in nuclei leads to the appearance of a three-body force between the dibaryon and nuclear core. This non-conventional scalar force is shown to provide an additional attractive contribution to the three-body binding energy. This three-body contribution improves noticeably agreement between theoretical results and experimental data for the majority of observables. The most serious difference between the traditional $NN$-force models and the dibaryon-induced model is found for the nucleon momentum distribution, the latter model providing a strong enrichment of the high-momentum components both for $^6$Li and $^6$He cases.

description: We present a complete next-to-leading order (NLO) calculation for the total cross section of inclusive Higgs pair production via bottom-quark fusion ($b\bar{b} \to hh$) at the CERN Large Hadron Collider (LHC) in the Standard Model. The NLO QCD corrections lead to less dependence on the renormalization scale ($μ_R$) and the factorization scale ($μ_F$) than the leading-order (LO) cross section, and they significantly increase the LO cross section. The rate for inclusive Higgs pair production is small in the Standard Model, but can be large in models with enhanced couplings of the $b$ quark to the Higgs bosons.

description: Efficient heat dissipation to the substrate is crucial for optimal device performance in nanoelectronics. We develop a theory of electronic thermal boundary conductance (TBC) mediated by remote phonon scattering for the single-layer transition metal dichalcogenide (TMD) semiconductors MoS$_{2}$ and WS$_{2}$, and model their electronic TBC with different dielectric substrates (SiO$_{2}$, HfO$_{2}$ and Al$_{2}$O$_{3}$). Our results indicate that the electronic TBC is strongly dependent on the electron density, suggesting that it can be modulated by the gate electrode in field-effect transistors, and this effect is most pronounced with Al$_{2}$O$_{3}$. Our work paves the way for the design of novel thermal devices with gate-tunable cross-plane heat-dissipative properties.

description: Το φανταστικό μπορεί να κάνει χωρίς τη σάτιρα πολύ καλύτερα απ’ ότι μπορεί η σάτιρα χωρίς το φανταστικό, σημειώνει ο F. Rassell. Αυτήν ακριβώς την σχέση των δύο γενών ερευνήσαμε σ’ αυτή τη μελέτη και συνειδητοποιήσαμε πόσο βαθιά μπορεί να είναι η σύνδεσή τους και πόσο παραπλανητικά μπορεί ν’ αποδειχθούν κάποια στοιχεία ενός λογοτεχνικού κειμένου. Ένα έργο στο οποίο υπάρχουν υπερφυσικά πρόσωπα ή γεγονότα, όπως η Μεταμόρφωση και Το Σόλο, που δεν μπορούν να γίνουν αποδεκτά σύμφωνα με τους φυσικούς νόμους, δεν το καθιστούν απαραίτητα ένα κείμενο του φανταστικού. Από την άλλη πλευρά, η σάτιρα δεν συνδέεται αναγκαστικά και μόνο με το γέλιο αλλά μπορεί να έχει πιο σκοτεινό και δραματικό ύφος, ιδιαίτερα αν μιλούμε για γκροτέσκικη σάτιρα στην οποία μάλιστα αυτή η σκοτεινή πλευρά αποτελεί προϋπόθεσή της. Επίσης στην συγκεκριμένη μελέτη, καταρρίφτηκε μέσα από συγκεκριμένα επιχειρήματα η κατάταξη των δύο έργων στο φανταστικό και προτάθηκε μια σατιρική ανάγνωση, ενώ ταυτόχρονα αναδείχθηκαν ερμηνευτικά τα κοινά σημεία των δύο βασικών ηρώων. Αυτό που υπερισχύει και στα δύο έργα είναι η επίθεση, μια επίθεση συγχρονισμένη με το γέλιο κι ο εκσφενδονισμός, όχι μιας λύσης, αλλά ενός σαφούς μηνύματος. Ο Kafka κι ο Σκαρίμπας επιλέγουν να γελοιοποιήσουν τα θύματά τους αλλά και να εξορίσουν, να εξαφανίσουν τους βασικούς ήρωές τους, επιτυγχάνοντας, παρά τα φαινόμενα, μιας πρώτης τάξεως σατιρική εκδίκηση. Αυτοκαταστροφική μεν, σίγουρα όμως εκδίκηση, σίγουρα όμως επίθεση.
description: Fantastic can exist without satire much easier than satire can exist without fantastic, says F. Rassell. It is this relationship of these two genres that we studied in this paper and we realized how deep the connection can be and how misleading some points of a text can be proved. A writing, where we find supernatural creatures or events, like Metomorphosis and The Solo, that cannot be accepted according to natural lows, do not necessarily make it a text of the fantastic. On the other hand, satire does not necessarily connects only with laughter but it can show a more dark and dramatic face, especially if we are referring to grotesque satire, in which this dark side is actually a condition. In this paper there has also been vitiated the classification of the two novels in the genre of fantastic, it has been proposed a satirical reading and simultaneously there has been revealed the common points of the two basic heroes. The dominating element is an aggression combined with laughter and a cast, not of a solution, but of a specific message. Kafka and Skaribas choose to ridicule their victims, but also banish and eliminate both their basic heroes achieving, in our point of view, a satirical, first rate attack and revenge.
Phase transition into Instanton Crystal

description: We propose a class of models exhibiting instanton crystal phase. In this phase, the minimum of the free energy corresponds to a configuration with an imaginary-time-dependent order parameter in a form of a chain of alternating instantons and antiinstantons. The resulting characteristic feature of this state is that the average of the order parameter over the imaginary time vanishes. In order to study the model in a broad region of parameters of the model quantitatively, and prove the existence of the instanton crystal phase, we develop an efficient numerical scheme, suitable for the exact treatment of the proposed models. In a certain limit, results demonstrating the existence of the instanton crystal phase are obtained also analytically. The numerical study of the model shows that there is a phase transition between the instanton crystal and the state with the imaginary-time-independent order parameter.

description: Farnsworth Field is located in Ochiltree, Texas and has been selected for a Carbon Capture Utilization and Storage (CCUS) project that is being supported by the Department of Energy, the Southwest Regional Partnership on Carbon Sequestration, and Chaparral Energy Co. LLC. One million tonnes of 100% CO2 produced from the Arkalon Ethanol Plant in Liberal KS and the Agrium Fertilizer Plant in Borger TX will be injected into the Morrow B formation and monitored using seismic. Previous geologic characterization hypothesizes that the Morrow B Formation was an incised valley depositional environment. This study focuses on the 3D Vertical Seismic Profile (VSP) survey that overlaps two injection wells covering an area of approximately 1 by 2 miles. The purpose of this study is to geologically characterize the 3D VSP using seismic attributes and well logs. The Morrow B was auto picked in the 3D VSP data using gamma ray logs to locate the formation in depth. Low amplitude lens features that resemble channels were manually picked within the Morrow B. Seismic attributes aided in the geologic characterization by providing lithologic and stratigraphic interpretations. The attributes discussed in this study are curvature, instantaneous frequency, signal envelope, sweetness, relative acoustic impedance, chaos, root mean square amplitude, and variance. An unsupervised neural network was utilized to compare the seismic attributes to find similarities that might relate to geology. The possible channel interpretation can influence CO2 flow through the reservoir and have an effect on production and storage.

description: Climate disruptions threaten water systems and undermine economic growth in urban areas. Stakeholder perspectives for desalination and water reuse are not well known in Texas (USA) although utilities are implementing these water augmentation technologies for municipal and industrial purposes. We use a water portfolio-informed deployment of Q-methodology to identify three social perspectives: Diversification is Key, Conservation Before Desalination, and Private Sector Can Do It. We expected to find strongly supportive and opposed social perspectives, but found nuanced and contingent support for desalination and water reuse. Social perspectives were aware of the financial and political costs of desalination and reuse and did not want desalination and water reuse to reduce the importance of protecting currently sources of potable water in Texas. Cross-cutting themes include the predominance of desalination as the policy-relevant water supply alternative and concerns for human capital at levels ranging from desalination plant operators to legal experts.

description: The formation of three oxidative DNA 5-methylcytosine (5mC) modifications (oxi-mCs), 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC), by the TET/JBP family of dioxygenases, prompted intensive studies of their functional roles in mammalian cells. However, the functional interplay of these less abundant modified nucleotides in other eukaryotic lineages remains poorly understood. We carried out a systematic study of the content and distribution of oxi-mCs in DNA and RNA of the basidiomycetes Laccaria bicolor and Coprinopsis cinerea which are established models to study DNA methylation, developmental and symbiotic processes. Quantitative liquid chromatography-tandem mass spectrometry revealed persistent but uneven occurrence of 5hmC, 5fC and 5caC in DNA and RNA of the two organisms, which could be upregulated by vitamin C. 5caC in RNA (5carC) was predominantly found in non-ribosomal RNA fractions which potentially include non-coding, messenger and small RNA species. Mapping of 5hmC and 5fC genome-wide using the single CG analysis techniques hmTOP-seq and foTOP-seq pointed at involvement of oxi-mCs in regulation of gene expression and silencing of transposable elements. The implicated diverse roles of 5mC and oxi-mCs in the two fungi highlight the epigenetic importance of the latter modifications which are often neglected in standard whole-genome bisulfite analyses.

Οι κόκκοι περιβάλλονται από μια φωσφολιπιδική μεμβράνη με προσκολλημένες πρωτεϊνες όπως η PHA σύνθεση, PHA αποπολυμεράση κτλ. Σε έλλειψη άνθρακα, οι ΜΟ αποικοδομούν τους πολυεστέρες με τις ενδοκυττάριες PHA αποπολυμεράσες, σε μικρότερες ενώσεις που μπορούν να χρησιμοποιηθούν ως πηγή άνθρακα. Τα βακτήρια που βιοσυνθέτουν PHA ταξινομούνται σε 4 ομάδες, που βασίζονται στην οργάνωση της PHA περιοχής και των δομικών και λειτουργικών ιδιοτήτων των PHA συνθεσών. Οι PHA συνθάσες είναι τα ένζυμα-κλειδιά στη βιοσύνθεση των PHA και καταλύουν την στερεο-εκλεκτική μετατροπή των (l)-3-υδροζυάκης-συνενζύμου Α υποστρωμάτων σε PHAs με την απελευθέρωση συνενζύμου Α.

Η διερεύνηση του μηχανισμού της βιοσύνθεσης των PHA σ' ένα θερμόφιλο βακτήριο, ίσως οδηγήσει σε πολυμερή με βελτιωμένες ιδιότητες.
description: Polyhydroxyalkanoic acids (PHAs) are carbon and energy storage polymers synthesized by most embecteria and archea in response to environmental conditions, such as an excess of carbon source and a limitation of the other nutrients. PHA granules are surrounded by a phospholipid membrane with embedded, or attached proteins such as PHA synthese, PHA depolymerase, amphiphilic phasing proteins etc. when carbon starvation occurs, microorganisms degrade polyesters by intracellular PHA depolymerases to smaller compounds that can be used as carbon source. The PHA biosynthetic bacteria are classified into four groups based on the organization of the PHA locus, and the structure-function properties of the PHA synthases. PHA synthases are the key enzymes in the biosynthesis of PHA and catalyse the stereo-selective conversion of (R)-3-hydroxyacyl-CoA substretes to PHAs with the release of CoA. In our previous work (Pantaraki, et.al.) the purification and characterization of a PHA synthese from Thermus thermophilus HB8 was reported. Although the entire genome of T. thermophilus has been published a large number of ORFs still remains as hypothetical proteins, including the phaloci. In this study PCR-based methods were employed for the identification of PHA biosynthesis genes in T. thermophilus genome. Elucidation of the mechanism of PHA biosynthesis in a thermophilic bacterium may lead to polymers with improved properties.
How elementary school teachers use computers with their students in the one-computer classroom
Creators: name: Phillips, Patricia Anne
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to discover how the single classroom computer is being used by elementary school teachers with their students in one school district in British Columbia. Questionnaires were completed by 89 respondents, resulting in a response rate of 71%. In-depth interviews were conducted on a sample of 16 of those respondents. Some of the variables investigated included the personal background and data of teachers, the hardware and software details of their single classroom computer, how they integrated the computer into the curriculum, student computer use and factors impacting the use of the computer. The study found that single classroom computers are being used for a variety of purposes. Games and word processing were reported to be used most frequently in the classroom. Teachers also identified a number of factors that affected the use of the computer. Those factors included issues of time, adequate and reliable hardware and software and training needs. The conceptual framework on which the study's findings were examined was Fullan's (1991, 1992) theory of curriculum implementation and change. Fullan's factors of clarity, complexity, quality/practicality and need were considered in interpreting the results of this study. The findings in the present study were consistent with Fullan's contention that change is multidimensional and difficult to implement. The data suggest that the single classroom computer at the elementary school level faces a number of challenges to its implementation. Finding the time and opportunities to learn about their classroom computers, as well as gaining access to upgraded hardware and current software are among the challenges teachers face in their efforts to implement the single classroom computer.

description: The Andromeda (M31) galaxy displays several substructures in its inner halo whose origin as remnants of accreted satellites or perturbations of the pre-existing disc are encoded in the properties of their stellar populations (SPs), leaving traces on their deep [OIII] 5007 Åplanetary nebulae luminosity functions (PNLFs). By characterizing the morphology of the PNLFs, we constrain their origin. From our 54 sq. deg. deep narrow-band [OIII] survey of M31, we identify planetary nebulae (PNe) in the M31 disc and six major inner-halo substructures - the Giant Stream, North East Shelf, G1-Clump, Northern Clump, Western Shelf and Stream-D. We measure PNLF parameters from cumulative fits and statistically compare the PNLFs in each substructure and the disc. We link the PNLF parameters and those for the Large Magellanic Cloud to published metallicities and age measurements for their parent SPs. The absolute magnitudes of the PNLF bright cut-off ($M^{*}$) for these sub-populations span a significant magnitude range, despite having similar distance and line-of-sight extinction. $M^{*}$ for the Giant Stream, W-shelf and Stream-D PNLFs are fainter than those predicted by PN evolution models for the metallicity of the parent SPs. The faint-end slope of the PNLF increases linearly with decreasing fraction of stellar mass younger than 5 Gyr across the M31 regions and the LMC. From their PNLFs, the Giant Stream and NE-shelf are consistent with being stellar debris from an infalling satellite, while the G1 Clump appears to be linked with the pre-merger disc. The SPs of the substructures are consistent with those predicted by simulations of a single massive merger event that took place 2--3 Gyr ago in M31. Stream-D has an unrelated, distinct, origin. Furthermore, this study provides independent evidence that the faint-end of the PNLF is preferentially populated by PNe evolved from older stars.

description: Classes of (p,q)-deformations of the Jaynes-Cummings model in the rotating wave approximation are considered. Diagonalization of the Hamiltonian is performed exactly, leading to useful spectral decompositions of a series of relevant operators. The latter include ladder operators acting between adjacent energy eigenstates within two separate infinite discrete towers, except for a singleton state. These ladder operators allow for the construction of (p,q)-deformed vector coherent states. Using (p,q)-arithmetics, explicit and exact solutions to the associated moment problem are displayed, providing new classes of coherent states for such models. Finally, in the limit of decoupled spin sectors, our analysis translates into (p,q)-deformations of the supersymmetric harmonic oscillator, such that the two supersymmetric sectors get intertwined through the action of the ladder operators as well as in the associated coherent states.

Το πειραματικό σχέδιο που χρησιμοποιήθηκε ήταν τυχαιοποιημένες πλήρεις ομάδες με τρεις επαναλήψεις και το πείραμα εγκαταστάθηκε στο Ινστιτούτο Σιτηρών Θεσσαλονίκης, την καλλιεργητική περίοδο 2006 – 2007. Τα κριτήρια που εφαρμόστηκαν ήταν 1) η αξιολόγηση των F2 πληθυσμών, 2) η υπεροχή τους σε σχέση με την μέση τιμή των γονέων, 3) η υπεροχή ή υστέρηση σε σχέση με τον υψηλοαποδοτικό γονέα και 4) η υπεροχή ή υστέρηση με το δίκτυο των μαρτύρων ποικιλιών, τα οποία θα καθορίσουν τις ελπιδοφόρες διασταυρώσεις στους πληθυσμούς των οποίων θα ξεκινήσει η επιλογή. Από την ανάλυση των αποτελεσμάτων προέκυψε ότι ως προς: την απόδοση 8 F2 υπερείχαν της συνολικής μέσης τιμής των 15 F2, από την μέση τιμή των γονέων και τον μέσο όρο των μαρτύρων δύο F2 υπερείχαν σημαντικά, ενώ καμία F2 δεν ξεπέρασε σημαντικά τον υψηλοαποδοτικό γονέα. Η πιο υψηλοαποδοτική F2 ήταν η ΟΡΦΕΑΣ*ΩΡΩΠΟΣ η οποία υπερείχε σημαντικά σε τρία από τα τέσσερα κριτήρια αξιολόγησης. Από τις ποικιλίες η ΓΕΚΟΡΑ – Ε συμμετείχε περισσότερο στην διαμόρφωση του πειραματικού σφάλματος και είχε τον μικρότερο συντελεστή ομοιόστασης. Για τα χαρακτηριστικά ποιότητας, υπήρχαν F2 που έδωσαν ικανοποιητικά αποτελέσματα και θα μπορούσε να γίνει επιλογή για βελτίωση απόδοσης και ποιότητας.
description: Fifteen F2 populations and their six parents were evaluated for agronomic and quality. The experimental design used was a randomized complete block design with three replications. The experiment was conducted in the Cereals Institute of Thessaloniki during 2006 – 2007. The criteria applied were 1) the evaluation of F2 crosses 2) the superiority of the F2 over the mid – parent value 3) the superiority over the best – parent value 4) the superiority over the check cultivars network, that will determine the most promising F2 crosses, for fyrther selection. As far as yield is concerned 8F2 85 surpassed the mean yield of the total 15F2, 13F2 out yielded the mid parent and the six – parent mean. Two of the F2 populations yielded higher than the mid value of their parents significantly but none of the F2 surpassed significantly the best parent. The best F2 was ORFEAS*OROPOS which yielded significantly higher in three out of the four criteria applied. As long as check cultivars are concerned, YECORA - E had the highest contribution to the experimental error and the lowest coefficient of homeostasis. As far as the quality traits is concerned there were F2 populations which equaled the parents. This indicates that selection for both yield and quality might be feasible.

description: Electro-optical (EO) methods are nowadays well-proven diagnostic tools, which are utilized to detect THz fields in countless experiments. The world’s first near-field EO sampling monitor at an electron storage ring was developed and installed at the KIT storage ring KARA (Karlsruhe Research Accelerator) and optimized to detect longitudinal bunch profiles. This experiment with other diagnostic techniques builds a distributed, synchronized sensor network to gain comprehensive data about the phase-space of electron bunches as well as the produced coherent synchrotron radiation (CSR). These measurements facilitate studies of physical conditions to provide, at the end, intense and stable CSR in the THz range. At KIT, we also operate FLUTE (Ferninfrarot Linac- und Test-Experiment), a new compact versatile linear accelerator as a test facility for novel techniques and diagnostics. There, EO diagnostics will be implemented to open up possibilities to evaluate and compare new techniques for longitudinal bunch diagnostics. In this contribution, we will give an overview of results achieved, the current status of the EO diagnostic setups at KARA and FLUTE and discuss future prospects.

description: Josephson effect in junctions between unconventional superconductors is studied theoretically within the model describing the effects of interface roughness. The particularly important issue of applicability of the frequently used Sigrist-Rice formula for Josephson current in d-wave superconductor / insulator / d-wave superconductor junctions is addressed. We show that although the SR formula is not applicable in the ballistic case, it works well for rough interfaces when the diffusive normal metal regions exist between the d-wave superconductor and the insulator. It is shown that the SR approach only takes into account the component of the d-wave pair potential symmetric with respect to an inversion around the plane perpendicular to the interface. Similar formula can be derived for general unconventional superconductors with arbitrary angular momentum l.

Innovation in teacher practice: issues that arise as a teacher introduces technology enhanced instruction

Publisher: name: University of British Columbia

description: Previous studies have examined the use of computer-based activities as instructional and learning tools in science classrooms. Studies have examined the use of various hardware and software devices as well as student attitudes and student achievement after working with computer-based activities in science classrooms. Recently, a working pedagogical model that incorporates computer-based technologies into science instruction has been developed and studied in British Columbia schools. The model is called Technology Enhanced Secondary Science Instruction (TESSI). Student attitudes and achievement have been studied under this model, but little research has addressed the practical issues involved in the implementation of computer-based activities from the perspective of an innovating teacher. This study presents a teacher-researcher action research investigation of the issues that a teacher experiences in the use of computer-based activities while developing the TESSI model for the Chemistry 11 and 12 classrooms. Action research methodology provides a useful tool for analysis of practical problems important to professionals. Teachers, practitioners of the art of teaching, may employ action research to study their practical questions and secure a voice in academic literature. Using a teacher-researcher framework to examine problems related to their practice, teachers can describe and interpret cases from an "insider's" perspective.

description: Recently there has been increasing interest in alternate methods to compute quantum tunneling in field theory. Of particular interest is a stochastic approach which involves (i) sampling from the free theory Gaussian approximation to the Wigner distribution in order to obtain stochastic initial conditions for the field and momentum conjugate, then (ii) evolving under the classical field equations of motion, which leads to random bubble formation. Previous work showed parametric agreement between the logarithm of the tunneling rate in this stochastic approach and the usual instanton approximation. However, recent work [1] claimed excellent agreement between these methods. Here we show that this approach does not in fact match precisely; the stochastic method tends to overpredict the instanton tunneling rate. To quantify this, we parameterize the standard deviations in the initial stochastic fluctuations by $εσ$, where $σ$ is the actual standard deviation of the Gaussian distribution and $ε$ is a fudge factor; $ε= 1$ is the physical value. We numerically implement the stochastic approach to obtain the bubble formation rate for a range of potentials in 1+1-dimensions, finding that $ε$ always needs to be somewhat smaller than unity to suppress the otherwise much larger stochastic rates towards the instanton rates; for example, in the potential of [1] one needs $ε\approx 1/2$. We find that a mismatch in predictions also occurs when sampling from other Wigner distributions, and in single particle quantum mechanics even when the initial quantum system is prepared in an exact Gaussian state. If the goal is to obtain agreement between the two methods, our results show that the stochastic approach would be useful if a prescription to specify optimal fudge factors for fluctuations can be developed.

description: Being able to parse code-switched (CS) utterances, such as Spanish+English or Hindi+English, is essential to democratize task-oriented semantic parsing systems for certain locales. In this work, we focus on Spanglish (Spanish+English) and release a dataset, CSTOP, containing 5800 CS utterances alongside their semantic parses. We examine the CS generalizability of various Cross-lingual (XL) models and exhibit the advantage of pre-trained XL language models when data for only one language is present. As such, we focus on improving the pre-trained models for the case when only English corpus alongside either zero or a few CS training instances are available. We propose two data augmentation methods for the zero-shot and the few-shot settings: fine-tune using translate-and-align and augment using a generation model followed by match-and-filter. Combining the few-shot setting with the above improvements decreases the initial 30-point accuracy gap between the zero-shot and the full-data settings by two thirds.
Neutrino Flavor States and the Quantum Theory of Neutrino Oscillations

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The standard theory of neutrino oscillations is reviewed, highlighting the main assumptions: the definition of the flavor states, the equal-momentum assumption and the time = distance assumption. It is shown that the standard flavor states are correct approximations of the states that describe neutrinos in oscillation experiments. The equal-momentum assumption is shown to be unnecessary for the derivation of the oscillation probability. The time = distance assumption derives from the wave-packet character of the propagating neutrinos. We present a simple quantum-mechanical wave-packet model which allows us to describe the coherence and localization of neutrino oscillations.

description: The coherence of state-of-the-art superconducting qubit devices is predominantly limited by two-level-system defects, found primarily at amorphous interface layers. Reducing microwave loss from these interfaces by proper surface treatments is key to push the device performance forward. Here, we study niobium resonators after removing the native oxides with a hydrofluoric acid etch. We investigate the reappearance of microwave losses introduced by surface oxides that grow after exposure to the ambient environment. We find that losses in quantum devices are reduced by an order of magnitude, with internal Q-factors reaching up to 7 $\cdot$ 10$^6$ in the single photon regime, when devices are exposed to ambient conditions for 16 min. Furthermore, we observe that Nb2O5 is the only surface oxide that grows significantly within the first 200 hours, following the extended Cabrera-Mott growth model. In this time, microwave losses scale linearly with the Nb$_2$O$_5$ thickness, with an extracted loss tangent tan$δ$ = 9.9 $\cdot$ 10$^{-3}$. Our findings are of particular interest for devices spanning from superconducting qubits, quantum-limited amplifiers, microwave kinetic inductance detectors to single photon detectors.

IPCC

description: The Data Distribution Centre (DDC) of the Intergovernmental Panel on Climate Change (IPCC) was established in 1997 to facilitate the timely distribution of a consistent set of up-to-date scenarios of changes in climate and related environmental and socio-economic factors for use in climate impacts assessments, particularly to support the periodic IPCC Assessment Reports. This work could be seen as helping to bridge the gap between intercomparison of models which is conducted within CMIP (Coupled Model Intercomparison Project) and the broader problem of assessing climate change. This presentation will explore two key aspects of this work: firstly, supporting the exchange of data between the physical climate, climate impacts and socio-economic science domains and, secondly, ensuring that data used in assessments, which may be from dynamic research projects, is reliably curated to ensure long term access and proper tracking of data usage. These activities play a critical role in enabling robust assessments by an extended community effort while maintaining transparent data provenance. Our work is underpinned by engagement with the World Data System.
