description: Molecules with unstable isotopes often contain heavy and deformed nuclei and thus possess a high sensitivity to parity-violating effects, such as Schiff moments. Currently the best limits on Schiff moments are set with diamagnetic atoms. Polar molecules with quantum-enhanced sensing capabilities, however, can offer better sensitivity. In this work, we consider the prototypical 223Fr107Ag molecule, as the octupole deformation of the unstable 223Fr francium nucleus amplifies the nuclear Schiff moment of the molecule by two orders of magnitude relative to that of spherical nuclei and as the silver atom has a large electronegativity. To develop a competitive experimental platform based on molecular quantum systems, 223Fr atoms and 107Ag atoms have to be brought together at ultracold temperatures. That is, we explore the prospects of forming 223Fr107Ag from laser-cooled Fr and Ag atoms. We have performed fully relativistic electronic-structure calculations of ground and excited states of FrAg that account for the strong spin-dependent relativistic effects of Fr and the strong ionic bond to Ag. In addition, we predict the nearest-neighbor densities of magnetic-field Feshbach resonances in ultracold 223Fr+107Ag collisions with coupled-channel calculations. These resonances can be used for magneto-association into ultracold, weakly-bound FrAg. We also determine the conditions for creating 223Fr107Ag molecules in their absolute ground state from these weakly-bound dimers via stimulated Raman adiabatic passage using our calculations of the relativistic transition electronic dipole moments.

description: In this paper, we present a data-driven analysis of the $γγ\to D^+D^-$ and $γγ\to D^0\bar{D}^0$ reactions from threshold up to 4.0 GeV in the $D\bar{D}$ invariant mass. For the $S$-wave contribution, we adopt a partial-wave dispersive representation, which is solved using the $N/D$ ansatz. The left-hand cuts are accounted for using the model-independent conformal expansion. The $D$-wave $χ_{c2}(3930)$ state is described as a Breit-Wigner resonance. The resulting fits are consistent with the data on the invariant mass distribution of the $e^+e^- \to J/ψD\bar{D}$ process. Performing an analytic continuation to the complex $s$-plane, we find no evidence of a pole corresponding to the broad resonance $X(3860)$ reported by the Belle Collaboration. Instead, we find a clear bound state below the $D\bar{D}$ threshold at $\sqrt{s_B} = 3695(4)$ MeV, confirming the previous phenomenological and lattice predictions.

description: In this article, we describe a project management course developed in a multi-campus, blended learning environment, with the participation of 14 NGOs. There were 70 undergraduate students involved, from three campuses of the Federal University of São Paulo, Brazil. We discuss how the course was conceptualized, provide an outline of its curriculum and online components, and analyze its successes and failures. To gather data, we used a convergent parallel mixed method approach, and we analyzed this data by means of a systemic analysis.


We found that working with real clients on real projects, in a multi-campus blended learning environment, increases the students’ motivation to learn, develop skills, and complete projects. However, the occurrence of students dropping out of the course is demotivating and stressful to the remaining students and to the community partners.


We also found that the distances involved (between campuses and between campuses and NGO facilities), along with course schedule conflicts, make it difficult to establish rhythms between face-to-face activities and online activities. However, we also found that the intensive use of information technology can help overcome problems caused by distance and course schedule conflicts.

Critiquing two exhibitions - Semiramis: Dark Continent by Tai Shani at Tramway, Glasgow 2018 and Turner Contemporary, Margate 2019 and Child of Magohalmi and the Echoes of Creation by Zadie Xa at De La Warr, East Sussex, 2020 - I will consider the implications of the complexity of feminist conceptions of experience pointed to through these works and the material interpretations that highlight those concepts through installation and performance.

description: We show theoretically that dark solitons can exist in the presence of pure quartic dispersion, and also in the presence of both quadratic and quartic dispersive effects, displaying a much greater variety of possible solutions and dynamics than for pure quadratic dispersion. The interplay of the two dispersion orders may lead to oscillatory non-vanishing tails, which enables the possibility of bound, potentially stable, multi-soliton states. Dark soliton-like states which connect to low amplitude oscillations are also shown to be possible. Dynamical evolution results corroborate the stability picture obtained, and possible avenues for dark soliton generation are explored.

Measuring the sound horizon and absolute magnitude of SNIa by maximizing the consistency between low-redshift data sets

subject: FOS: Physical sciences

description: The comoving sound horizon at the baryon drag epoch, $r_{d}$, encapsulates very important physical information about the pre-recombination era and serves as a cosmic standard ruler. On the other hand, the absolute magnitude of supernovae of Type Ia (SNIa), $M$, is pivotal to infer the distances to these standard candles. Having access to (at least) one of these two quantities is crucial to measure the Hubble parameter $H_0$ from BAO/SNIa data. In this work we present a new method to measure how long is the cosmic ruler and how bright are the standard candles independently from the main drivers of the $H_0$ tension, namely by avoiding (i) the use of CMB data; (ii) the calibration of SNIa in the first steps of the cosmic distance ladder; and (iii) the assumption of any concrete cosmological model. We only assume that SNIa can be safely employed as standard candles and $r_d$ as a standard ruler, together with the validity of the Cosmological Principle and the metric description of gravity, with photons propagating in null geodesics and the conservation of the photon number. Our method is based on the minimization of a loss function that represents the level of inconsistency between the low-redshift data sets employed in this study, to wit: SNIa, BAO and cosmic chronometers. In our main analysis we obtain: $r_d=(146.0^{+4.2}_{-5.1})$ Mpc, $M=-19.362^{+0.078}_{-0.067}$. The former is fully compatible with Planck's $Λ$CDM best-fit cosmology, but still leaves plenty of room for new physics before the decoupling, whereas our constraint on $M$ lies closer to the value preferred by the concordance model, although it is only $\sim 1.4σ$ below the SH0ES measurement.

description: In this paper, we aim at using the DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO), a future Japanese space gravitational-wave antenna sensitive to frequency range between LISA and ground-based detectors, to provide gravitational-wave constraints on the cosmic curvature at $z\sim 5$. In the framework of the well-known distance sum rule, the perfect redshift coverage of the standard sirens observed by DECIGO, compared with lensing observations including the source and lens from LSST, makes such cosmological-model-independent test more natural and general. Focusing on three kinds of spherically symmetric mass distributions for the lensing galaxies, we find that the cosmic curvature is expected to be constrained with the precision of $ΔΩ_K \sim 10^{-2}$ in the early universe ($z\sim5.0$), improving the sensitivity of ET constraints by about a factor of 10. However, in order to investigate this further, the mass density profiles of early-type galaxies should be properly taken into account. Specially, our analysis demonstrates the strong degeneracy between the spatial curvature and the lens parameters, especially the redshift evolution of power-law lens index parameter. When the extended power law mass density profile is assumed, the weakest constraint on the cosmic curvature can be obtained. Whereas, the addition of DECIGO to the combination of LSST+DECIGO does improve the constraint on the luminosity density slope and the anisotropy of the stellar velocity dispersion significantly. Therefore, our paper highlights the benefits of synergies between DECIGO and LSST in constraining new physics beyond the standard model, which could manifest itself through accurate determination of the cosmic curvature.

description: This article reflects on recent developments in the author's fine art research project, Monsters and Margins. The imposing of lockdown restrictions in 2020 initiated a shift in the artist’s practice, resulting in him spray painting and projecting Doctor Who villains onto the Brutalist architecture of the Queen Elizabeth II Bridge. The author will demonstrate the influence of literature and philosophy on his artistic practice, drawing upon the work of Robert Smithson, J.G. Ballard, Iain Sinclair and, most pertinently, Mark Fisher, as he narrates the evolution of his understanding of hauntology and psycho-geography through progressing experiments. This leads to the unearthing of an anti-capitalist political stance in the work, enflamed by the pandemic’s highlighting of poor governance and society’s unsustainable consumerism and inequalities.

description: The primary secondary particles from the spallation target of the China Spallation Neutron Source are mainly gammas and neutrons, which are related to the distribution of the incident proton. The reconstruction of proton beam spot could be implemented based on the distribution of secondary particles. The methods of pinhole imaging and Compton imaging are developed by measuring the gamma distribution based on the pixelated detector. The secondary gammas could be detected by the pixelated gamma detector directly. The neutron can be identified by detecting the characteristic (478 keV) $γ$-rays from the $^{10}B$(n, $α$) reactions. In order to detect secondary neutrons, a layer of $^{10}B$ converter is added before the pixelated gamma detector. The pixelated gamma detector is sensitive to the characteristic (478 keV) $γ$-rays and then the neutron imaging could be achieved based on measuring the distribution of the characteristic gamma.

description: Characterising quantum states of light in the 2 $μm$ band requires high-performance shot-noise limited detectors. Here, we present the characterisation of a homodyne detector that we use to observe vacuum shot-noise via homodyne measurement with a 2.07 $μm$ pulsed mode-locked laser. The device is designed primarily for pulsed illumination. It has a 3 dB bandwidth of 13.2 MHz, total conversion efficiency of 58% at 2.07 $μm$ and a common-mode rejection ratio of 48 dB at 39.5 MHz. The detector begins to saturate at 1.8 mW with 9 dB of shot-noise clearance at 5 MHz. This demonstration enables the characterisation of megahertz-quantum optical behaviour in the 2 $μm$ band.

Profitability is one of the most important objectives of financial management because one goal of financial management is to maximize the owner` s wealth. This paper examined the effects of firm specific factors (age of company, size of company, volume of capital, leverage ratio, liquidity ratio, growth and tangibility of assets) on profitability proxied by ROA. Profitability is dependent variable while age of company, size of company, volume of capital, leverage liquidity ratio, growth and tangibility of assets) are independent variables. The sample in this study includes nine of the listed insurance companies for nine years (2003-2011). Secondary data obtained from the financial statements (Balance sheet and Profit/Loss account) of insurance companies, financial publications of NBE are analyzed. From the regression results; growth, leverage, volume of capital, size, and liquidity are identified as most important determinant factors of profitability hence growth, size, and volume of capita are positively related. In contrast, liquidity ratio and leverage ratio are negatively but significantly related with profitability. Lastly, age of company and tangibility of assets are not significantly related with profitability.

description: We present "Extending the Satellites Around Galactic Analogs Survey" (xSAGA), a method for identifying low-$z$ galaxies on the basis of optical imaging, and results on the spatial distributions of xSAGA satellites around host galaxies. Using spectroscopic redshift catalogs from the SAGA Survey as a training data set, we have optimized a convolutional neural network (CNN) to identify $z < 0.03$ galaxies from more distant objects using image cutouts from the DESI Legacy Imaging Surveys. From the sample of $> 100,000$ CNN-selected low-$z$ galaxies, we identify $>20,000$ probable satellites located between 36-300 projected kpc from NASA-Sloan Atlas central galaxies in the stellar mass range $9.5 < \log(M_\star/M_\odot) < 11$. We characterize the incompleteness and contamination for CNN-selected samples, and apply corrections in order to estimate the true number of satellites as a function of projected radial distance from their hosts. Satellite richness depends strongly on host stellar mass, such that more massive host galaxies have more satellites, and on host morphology, such that elliptical hosts have more satellites than disky hosts with comparable stellar masses. We also find a strong inverse correlation between satellite richness and the magnitude gap between a host and its brightest satellite. The normalized satellite radial distribution between 36-300 kpc does not depend strongly on host stellar mass, morphology, or magnitude gap. The satellite abundances and radial distributions we measure are in reasonable agreement with predictions from hydrodynamic simulations. Our results deliver unprecedented statistical power for studying satellite galaxy populations, and highlight the promise of using machine learning for extending galaxy samples of wide-area surveys.

description: Space-time evolution of spin polarization within the framework of hydrodynamics with spin based on de Groot - van Leeuwen - van Weert forms of energy-momentum and spin tensors is studied. Due to the non-boost invariant flow in the system the spin polarization components couple to each other implying some effects on the spin polarization observables. We study transverse-momentum and rapidity dependence of mean spin polarization vector for $Λ$ hyperons. Our results show qualitative agreement for rapidity dependence of the global spin polarization with the experiments and other models. The quadrupole structure of the longitudinal component at midrapidity is not found, however, as compared to the results for Bjorken expansion, some non-trivial signal at forward rapidities is observed.

Da die Reduktion der Treibhausgas-Emissionen bisher gar nicht oder nicht schnell genug erfolgte, wird intensiv auch über technische Methoden zur Entnahme von CO2 aus der Atmosphäre (Carbon Dioxide Removal, CDR) diskutiert, um das völkerrechtlich bindende Ziel zu erreichen. Es gibt zahlreiche Verfahren, mit denen CO2 aus der Atmosphäre entfernt werden kann, um neben der absolut vorrangigen Emissionsminderung Neto-Null-Emissionen zu erreichen. In diesem zusammenfassenden Artikel soll der potenzielle Beitrag der CDR-Methoden vorgestellt werden. Neben CDR-Methoden und denen des Strahlungsmanagements (radiation management, RM) werden auch Methoden der CO2-Nutzung und sowie der Dekarbonisierung in der Industrie behandelt.

description: Despite the huge improvements guaranteed by future GRAVITY observations of the S0-2 star, these will not be able to unveil the fundamental nature, whether black hole or wormhole, of the central supermassive object. Nevertheless, observing stars orbiting closer to the central gravitational source could allow to distinguish between the black hole and wormhole nature of this object at more than 5$σ$. Firstly, we have used publicly available astrometric and spectroscopic measurements of the S0-2 star to constrain the metric around the supermassive object without finding any evidence either favouring or ruling out the wormhole nature. Secondly, we have designed a mock catalogue of future observations of the S0-2 star mirroring the accuracy and precision of GRAVITY. Afterwards, we firstly tested our methodology showing that our procedure recovers the input model, and subsequently we demonstrated that the constraining power of such a dataset is not enough to distinguish between black hole and wormhole. Finally, we built some toy models representing stars orbiting much closer the central object than S0-2. We used these toy models to investigate which are the ideal orbital features and observational strategies to achieve our aim of unveiling the fundamental nature of the central supermassive object, demonstrating that a star with a period of the order of $\sim 5$ years and a pericentre distance of $\sim 5$ AU could identify the nature of the central object at almost 5$σ$ accuracy.

description: Recent in-situ observations from the Parker Solar Probe (PSP) mission in the inner heliosphere near perihelia show evidence of ion beams, temperature anisotropies, and kinetic wave activity, which are likely associated with kinetic heating and acceleration processes of the solar wind. In particular, the proton beams were detected by PSP/SPAN-I and related magnetic fluctuation spectra associated with ion-scale waves were observed by the FIELDS instrument. We present the ion velocity distribution functions (VDFs) from SPAN-I and the results of 2.5D and 3D hybrid-particle-in-cell (hybrid-PIC) models of proton and alpha particle super-Alfvenic beams that drive ion kinetic instabilities and waves in the inner-heliospheric solar wind. We model the evolution of the ion VDFs with beams, ion relative drifts speeds, and ion temperature anisotropies for solar wind conditions near PSP perihelia. We calculate the partition of energies between the particles (ions) along and perpendicular to the magnetic field, as well as the evolution of magnetic energy and compare to observationally deduced values. We conclude that the ion beam driven kinetic instabilities in the solar wind plasma near perihelia are important components in the cascade of energy from fluid to kinetic scale, an important component in the solar wind plasma heating process.

description: With the ongoing spread of Coronavirus, societies around the world have become aware of how inextricably linked we all are to the infrastructures that distribute the resources for everyday life. While infrastructures promise modernity and growth, their neglect and absence expose inequality and the fragility of progress. Continual maintenance and repair keep infrastructures functioning. Infrastructure systems are often hidden beneath the surface of urban life, only becoming apparent when their breakdown occurs. I propose presenting a brief overview of artists exploring how the often neglected and undervalued activities of maintenance and repair are shaped by race, gender, class, and other political, economic and cultural forces.

Specifically, the study looks into the impact of bank branch spread, ATM spread and bank loans to Small and medium enterprises on financial inclusion. The study adopted the expost facto research design and data was gotten from the financial statement of listed deposit money banks and CBN statistical bulltetin.  The study investigated twelve (12) listed deposit money banks from the period of 2018-2022. Panel least squares was used to estimate the models of the study. The findings of the study revealed that the penetration of financial services through bank branches has no significant impact on bank performance in Nigeria; The penetration of financial services through ATM spread has positive and significant effect on bank performance in Nigeria; The usage of financial services via SMEs loans has no significant impact on bank performance in Nigeria; The study concluded that financial inclusion has mixed influence on financial performance of banks in Nigeria. The study recommended that banks should continue to increase the number of branches in the rural areas to drive full financial inclusion which would in the long-run improve the financial performance of banks; The current drive of digital financial inclusion through ATM spread should be sustained to allow access of financial services to the unbanked population; The current volume of SMEs loans should be improved upon to drive financial inclusion and Banks should do more on cyber security to boost the usage of online banking services in driving digital financial inclusion.

description: Adopting the MPI-AMRVAC code, we present a 2.5-dimensional magnetohydrodynamic (MHD) simulation, which includes thermal conduction and radiative cooling, to investigate the formation and evolution of the coronal rain phenomenon. We perform the simulation in initially linear force-free magnetic fields which host chromospheric, transition region, and coronal plasma, with turbulent heating localized on their footpoints. Due to thermal instability, condensations start to occur at the loop top, and rebound shocks are generated by the siphon inflows. Condensations fragment into smaller blobs moving downwards and as they hit the lower atmosphere, concurrent upflows are triggered. Larger clumps show us clear "coronal rain showers" as dark structures in synthetic EUV hot channels and bright blobs with cool cores in the 304 Å channel, well resembling real observations. Following coronal rain dynamics for more than 10 hours, we carry out a statistical study of all coronal rain blobs to quantify their widths, lengths, areas, velocity distributions, and other properties. The coronal rain shows us continuous heating-condensation cycles, as well as cycles in EUV emissions. Compared to previous studies adopting steady heating, the rain happens faster and in more erratic cycles. Although most blobs are falling downward, upward-moving blobs exist at basically every moment. We also track the movement of individual blobs to study their dynamics and the forces driving their movements. The blobs have a prominence-corona transition-region-like structure surrounding them, and their movements are dominated by the pressure evolution in the very dynamic loop system.

description: The correlation between the plasma density measured in space and the surface potential of an electrically conducting satellite body with biased electric field detectors has been recognized and used to provide density proxies. However, for Parker Solar Probe, this correlation has not produced quantitative density estimates over extended periods of time because it depends on the energy dependent exponential variation of the photoemission spectrum, the electron temperature, the ratio of the biased surface area to the conducting spacecraft surface area, the spacecraft secondary or thermal emission, the spacecraft distance from the Sun, etc. In this paper the density as a function of time and frequency to frequencies as high as the electron gyrofrequency is determined through least squares fits of a function of the spacecraft potential to the plasma density measured on the Parker Solar Probe. This function allows correction for the many effects on the spacecraft potential other than that due to the plasma density. Some examples of plasma density obtained from this procedure are presented.

description: The investigations of the interconnection between micro- and macroscopic properties of materials hosting noncollinear antiferromagnetic ground states are challenging. These forefront studies are crucial for unraveling the underlying mechanisms at play, which may prove beneficial in designing cutting edge multifunctional materials for future applications. In this context, Mn5Si3 has regained scientific interest since it displays an unusual and complex ground state, which is considered to be the origin of the anomalous transport and thermodynamic properties that it exhibits. Here, we report the magnetic exchange couplings of the noncollinear antiferromagnetic phase of Mn5Si3 using inelastic neutron scattering measurements and density functional theory calculations. We determine the ground-state spin configuration and compute its magnon dispersion relations which are in good agreement with the ones obtained experimentally. Furthermore, we investigate the evolution of the spin texture under the application of an external magnetic field to demonstrate theoretically the multiple field-induced phase transitions that Mn5Si3 undergoes. Finally, we model the stability of some of the material's magnetic moments under a magnetic field and we find that very susceptible magnetic moments in a frustrated arrangement can be tuned by the field.

description: The Paris Climate Agreement and the Importance of climate engineering: Stopping global warming requires Net-Zero CO2 emissions. Since it is not yet foreseeable that all emissions can be avoided by mid-century, the Net-Zero target set in the Paris Climate Agreement implies the use of CO2 removal methods that can be described as a category of climate engineering. Optimistic emission reduction scenarios assume that by mid-century, 5 to 15% of today's emissions will have to be offset by CO2 removal as difficult-to-avoid residual emissions. So-called "nature-based" solutions alone will not be sufficient to achieve this. Technical approaches will also have to be applied at large scale if the climate targets are to be achieved. None of these methods is ready for large-scale deployment today. Public research is needed and the societal debate on how to deal with residual emissions must begin quickly so that appropriate methods can be developed in time, well-informed societal decisions can be made about their eventual deployment, and mechanisms can be devised to regulate such deployment responsibly.

description: At the National Library of New Zealand and Archives New Zealand, the Utaina project undertakes the task to digitise 70,000 audiovisual items between 2020 and 2025, to digitally preserve collections and holdings that are stored on historical and nowobsolete at-risk magnetic media formats.

At this scale, the project confronts the pragmatic realities of digital preservation, where decisions are shaped by budget, time and resource constraints, while balancing the needs and sustainability of long-term preservation. This lightning talk delves into how these factors shaped our choices in formats, workflow designs and automation. It will also identify future opportunities where AI can be used to improve the digitised files and create new avenues for preservation and access to cultural heritage and government records.

description: Laser ablation is often explained by a two-temperature model (TTM) with different electron and lattice temperatures. To realize a classical molecular dynamics simulation of the TTM, we propose an extension of the embedded atom method to construct an interatomic potential that is dependent on the electron temperature. This method is applied to copper, and its validity is demonstrated by comparison of several physical properties, such as the energy-volume curve, phonon dispersion, electronic heat capacity, ablation threshold, and mean square displacement of atoms, with those of finite-temperature density functional theory.

description: Sufficient conditions are found on the ion velocity distribution $f_i$ and potential amplitude for stability of steady electron holes moving at slow speeds, coinciding with the bulk of $f_i$. Fully establishing stability requires calculation of the ion response to shift potential perturbations having an entire range of oscillatory frequencies, because under some conditions real frequencies intermediate between the ion and electron responses prove to be unstable even when the extremes are not. The mechanism of this overstability is explained and calculated in detail. Electron holes of peak potential $ψ$ less than approximately 0.01 times the background temperature ($ψ\lesssim 0.01T_0/e$) avoid the oscillatory instability entirely. For them, the \emph{necessary} condition that there be a local minimum in $f_i$ in which the hole resides is also \emph{sufficient}, unless the magnetic field $B$ is low enough to permit the transverse instability having finite wavenumber $k$ perpendicular to $B$.
Accessing subnuclear fluctuations and saturation with multiplicity dependent $J/ψ$ production in p+p and p+Pb collisions

description: We study the production of $J/ψ$ vector mesons as a function of charged hadron multiplicity in p+p and p+Pb collisions at LHC energies. We employ the color glass condensate framework, using running coupling Balitsky-Kovchegov evolved dipole amplitudes, to compute gluon and $c\bar{c}$-pair production. We use fragmentation functions to obtain charged hadrons, and explore two different hadronization schemes for the $J/ψ$: non-relativistic quantum chromodynamics and the improved color evaporation model. In our framework, event-by-event multiplicity fluctuations of both hadrons and $J/ψ$ are driven by geometric and saturation scale normalization fluctuations. Studying the correlation between $J/ψ$ and hadron multiplicity, we show that the characteristic difference between forward and backward rapidity in p+Pb collisions is a result of different degrees of saturation probed at different rapidities. We demonstrate that experimental data on heavy-flavor production as a function of event activity provide stringent constraints on the fluctuating proton structure.

description: Contexte : le nombre de requérants d’asile en Suisse ne fait qu’augmenter depuis ces dernières années. En tant qu’infirmières nous sommes amenées à soigner tout type de population, dont les patients issus de la migration. Les infirmières rencontrent un certain nombre de défis quant à la prise en soins de ces patients, notamment au niveau de la communication, c’est pourquoi le recours à un interprète communautaire semble indispensable. But : cette revue de littérature a pour objectif d’explorer et d’identifier les différents facteurs influençant la prise en soins des patients requérants d’asile au travers des interprètes communautaires, dans différents contextes de soins. Notre question de recherche est la suivante : Comment le recours aux interprètes communautaires influence-t-il la prise en soins des patients requérants d’asile ?
Globaler Kohlenstoffkreislauf – Wieviel CO2 bleibt jährlich in der Atmosphäre und wieviel Zeit haben wir noch?

description: Global carbon cycle - How much CO2 remains in the atmosphere each year? and how much time do we have left? The exchange of carbon between the surface reservoirs of atmosphere, land and ocean on the one hand and the deep geological reservoirs on the other has been considerably accelerated by human use of fossil fuels. The result is a warming of the global climate at a rate unprecedent in Earth's history over the past 50 million years. Whether anthropogenic climate change can be halted in time is uncertain. This also depends on the feedback processes between the carbon cycle and climate changes.
Collective resonance of $D$ states in rubidium atoms probed by optical two-dimensional coherent spectroscopy

description: Collective resonance of interacting particles has important implications in many-body quantum systems and their applications. Strong interactions can lead to a blockade that prohibits the excitation of a collective resonance of two or more nearby atoms. However, a collective resonance can be excited with the presence of weak interaction and has been observed for atoms in the first excited state ($P$ states). Here, we report the observation of collective resonance of rubidium atoms in a higher excited state ($D$ states) in addition to the first excited state. The collective resonance is excited by a double-quantum four-pulse excitation sequence. The resulting double-quantum two-dimensional (2D) spectrum displays well-isolated peaks that can be attributed to collective resonances of atoms in $P$ and $D$ states. The experimental one-quantum and double-quantum 2D spectra can be reproduced by a simulation based on the perturbative solutions to the optical Bloch equations, confirming collective resonances as the origin of the measured spectra. The experimental technique provides a new approach for preparing and probing collective resonances of atoms in highly excited states.

description: [Objectives] To explore effective biocontrol methods for diseases in the process of ginseng cultivation, and develop an efficient and environmentally friendly biocontrol agent. [Methods] In this study, 2 strains were isolated from biogas slurry, and Cylindrocarpon destructans (XF), Fusarium solani (GF), Botrytis cinerea Pers (HM) and Alternaria panax Whetz (HB) were used as test materials. The strains were isolated and identified by dilution plate method, 16S rDNA sequence identification method, confrontation culture method, filter paper method and ultraviolet spectrophotometer method, and the bacteriostatic activity and bacteriostatic rate were tested. [Results] Strain 15 (Sphingomonas) and strain 19 (Pseudomonas aeruginosa) were screened out through identification and analysis, and they grew stably within 8-10 d. The bacteriostatic rates of strain 15 against A. panax and B. cinerea were 47.37% and 43.40%, respectively, and the bacteriostatic rates of strain 19 against A. panax and B. cinerea were 62.30% and 63.27%, respectively. The bacteriostatic activity of the extract of strain 19 increased with the increase of OD600 value, and the bacteriostatic effect was optimal when the OD600 value was in the range of 0.8-1, up to about 70%, so it had a strong biocontrol potential. [Conclusions] This experiment provides convenience for more effective inoculation, establishes a fast, simple and accurate method for the determination of the best bacteriostatic rate of P. aeruginosa culture solution to HM, and lays a foundation for large-scale culture of P. aeruginosa culture solution. Besides, it is expected to provide a theoretical basis for the efficient control of ginseng B. cinerea in field production, use it for the prevention and control of ginseng shoot diseases, and provide a reference for the efficient and diverse development of biocontrol agents for ginseng shoot diseases.
