description: Gas convection is observed in the solar photosphere as the granulation, i.e., having highly time-dependent cellular patterns, consisting of numerous bright cells called granules and dark surrounding-channels called intergranular lanes. Many efforts have been made to characterize the granulation, which may be used as an energy source for various types of dynamical phenomena. Although the horizontal gas flow dynamics in intergranular lanes may play a vital role, but they are poorly understood. This is because the Doppler signals can be obtained only at the solar limb, where the signals are severely degraded by a foreshortening effect. To reduce such a degradation, we use Hinode's spectroscopic data, which are free from a seeing-induced image degradation, and improve its image quality by correcting for straylight in the instruments. The dataset continuously covers from the solar disk to the limb, providing a multidirectional line-of-sight (LOS) diagnosis against the granulation. The obtained LOS flow-field variation across the disk indicates a horizontal flow speed of 1.8-2.4 km/s. We also derive the spatial distribution of the horizontal flow speed, which is 1.6 km/s in granules and 1.8 km/s in intergranular lanes, and where the maximum speed is inside intergranular lanes. This result newly suggests the following sequence of horizontal flow: A hot rising gas parcel is strongly accelerated from the granular center, even beyond the transition from the granules to the intergranular lanes, resulting in the fastest speed inside the intergranular lanes, and the gas may also experience decelerations in the intergranular lane.

description: In this paper we construct negatively curved Einstein spaces describing gravitational waves having a solvegeometry wave-front (i.e., the wave-fronts are solvable Lie groups equipped with a left-invariant metric). Using the Einstein solvmanifolds (i.e., solvable Lie groups considered as manifolds) constructed in a previous paper as a starting point, we show that there also exist solvegeometry gravitational waves. Some geometric aspects are discussed and examples of spacetimes having additional symmetries are given, for example, spacetimes generalising the Kaigorodov solution. The solvegeometry gravitational waves are also examples of spacetimes which are indistinguishable by considering the scalar curvature invariants alone.

description: We study the duality group of $\hat{A}_{n-1}$ quiver gauge theories, primarily using their M5-brane construction. For $\mathcal{N}=2$ supersymmetry, this duality group was first noted by Witten to be the mapping class group of a torus with $n$ punctures. We find that it is a certain quotient of this group that acts faithfully on gauge couplings. This quotient group contains the affine Weyl group of $\hat{A}_{n-1}$, $\mathbb{Z}_n$ and $SL(2,\mathbb{Z})$. In fact there are $n$ non-commuting $SL(2,\mathbb{Z})$ subgroups, related to each other by conjugation using the $\mathbb{Z}_n$. When supersymmetry is broken to $\mathcal{N}=1$ by masses for the adjoint chiral superfields, an RG flow ensues which is believed to terminate at a CFT in the infrared. We find the explicit action of this duality group for small values of the adjoint masses, paying special attention to when the sum of the masses is non-zero. In the $\mathcal{N}=1$ CFT, Seiberg duality acts non-trivially on both gauge couplings and superpotential couplings and we interpret this duality as inherited from the $\mathcal{N}=2$ parent theory. We conjecture the action of S-duality in the CFT based on our results for small mass deformations. We also consider non-conformal deformations of these $\mathcal{N}=1$ theories. The cascading RG flows that ensue are a one-parameter generalization of those found by Klebanov and Strassler and by Cachazo {\it et. al.}. The universality exhibited by these flows is shown to be a simple consequence of paths generated by the action of the affine Weyl group.

description: Erfolg – ein omnipräsenter Begriff, der bei genauer Betrachtungsweise vielschichtig und komplex, in der Deutung meist verschwommen und subjektiv bewertbar ist. Auch in der Sozialen Arbeit ist Erfolg geprägt durch Heterogenität, wird von Dritten definiert und lässt viel Spielraum für Interpretationen offen. Diese Bachelorarbeit befasst sich mit Literatur und Studien rund um den Erfolgsdiskurs in der Sozialen Arbeit.
Es werden Merkmale, Besonderheiten und Aspekte, welche den Erfolg von sozialarbeiterischen Interventionen beeinflussen, veranschaulicht und bestimmende Faktoren für erfolgreiche Soziale Arbeit dargelegt. Zudem werden Anspruchsgruppen, welche Erfolg definieren, mit ihren Erwartungen, Interessen und Zielen, analysiert. Veranschaulicht wird dies am Handlungsfeld der wirtschaftlichen Sozialhilfe.
Die Arbeit zeigt auf, dass die Erfolgsvorstellungen der verschiedenen Stakeholder heterogen sind und keine allgemeingültige Definition von Erfolg in der Sozialhilfe wie auch in der Sozialen Arbeit im Allgemeinen auszumachen ist. Es lassen sich jedoch Überschneidungen und gemeinsame Nenner zwischen den Interessen, Zielen und Erwartungen erkennen. Diese können durch sozialarbeiterische Vorgehensweisen, welche auf berufsethischen Werten und fachlich-professionellen Ansprüchen der Profession beruhen, erreicht werden.
Dennoch befinden sich die Professionellen der Sozialen Arbeit in einem stetigen Balanceakt, in welchem sie die unterschiedlichen Vorstellungen von Erfolg koordinieren müssen. Aus den Erkenntnissen der Recherche werden von der Autorin Implikationen für die Fachkräfte für die berufliche Praxis abgeleitet, welche die Spannungsverhältnisse reduzieren und Entlastung bieten sollen.

description: We collected more than 300 high-resolution spectra of the 300 Myr old star BD+40 2790 (TOI-2076) over ~3 years. This star hosts three transiting planets discovered by TESS, with orbital periods ~10, 21, and 35 days. BD+40 2790 shows an activity-induced scatter larger than 30 m/s in the radial velocities. We employed different methods to measure the stellar radial velocities and several models to filter out the dominant stellar activity signal, in order to bring to light the planet-induced signals which are expected to have semi-amplitudes one order of magnitude lower. We evaluated the mass loss rate of the planetary atmospheres using photoionization hydrodynamic modeling. The dynamical analysis confirms that the three sub-Neptune-sized companions (our radius measurements are $R_b$=2.54$\pm$0.04, $R_c$=3.35$\pm$0.05, and $R_d$=3.29$\pm$0.06 $R_{\rm Earth}$) have masses in the planetary regime. We derive 3$σ$ upper limits below or close to the mass of Neptune for all the planets: 11--12, 12--13.5, and 14--19 $M_{\rm Earth}$ for planet $b$, $c$, and $d$ respectively. In the case of planet $d$, we found promising clues that the mass could be between ~7 and 8 $M_{\rm Earth}$, with a significance level between 2.3--2.5$σ$ (at best). This result must be further investigated using other analysis methods or using high-precision near-IR spectrographs to collect new radial velocities, which could be less affected by stellar activity. Atmospheric photo-evaporation simulations predict that BD+40~2790 b is currently losing its H-He gaseous envelope, which will be completely lost at an age within 0.5--3 Gyr if its current mass is lower than 12 $M_{\rm Earth}$. BD+40 2790 c could have a lower bulk density than $b$, and it could retain its atmosphere up to an age of 5 Gyr. For the outermost planet $d$, we predict almost negligible evolution of its mass and radius induced by photo-evaporation.

description: There is a decline in the consumption of traditional vegetables in PNG, which adversely affects family nutrition and is increasing the rates of malnutrition and obesity. Traditional vegetables are climatically adapted to PNG, require lower inputs, and are superior in food value when compared to globally popular vegetables. They have more essential nutrients, and historically provided a large proportion of the daily protein, vitamin and mineral intake in the village diet. Turning around the decline in consumption and supply of traditional vegetables will improve food and nutritional security. This is particularly true for remote and isolated communities and poor urban populations. Our research found that people lacked awareness of the nutritional value of traditional vegetables. People consider these vegetables to be ‘backward’ and ‘poverty’ food. Conversely, traditional vegetables connect strongly to culture and ‘home’. We trained smallholder farmers to manage pests and diseases and save the seeds of traditional vegetables to reduce their input costs. We worked with families and communities to increase their awareness of the nutritional value of traditional vegetables. We trained families in gardening and cooking so they could grow and cook a variety of nutritious food from their own gardens. We created fresh recipes for local vegetables. Next, we plan to work with maternal–child clinics linked to hospitals where mothers learn to make nutritious cheap food from their own gardens. We will run schoolbased programs involving teacher education, school gardens and incentivebased lunchboxes. Some growers have applied their seed-saving skills to setting up small-scale seed businesses.

Poor roots and weak stem: potential issues in STEM leadership programs

description: In continuing response to the No Child Left Behind (NCLB) Act of 2001, the United States (U.S.) Department of Education releases an annual appropriation of 180 million dollars for Mathematics and Science Partnerships (MSP), whose “overarching goal … is to increase students’ achievement in mathematics and science by increasing teachers’ content knowledge and pedagogical skills” (Merrill & Daugherty, 2010, 23). In their article, Merrill and Daugherty hail the MSP funded science, technology, engineering and mathematics (STEM) Education and Leadership Program at Illinois State University (ISU) as an example of the direction that many MSP funded STEM programs should take to address the needs of students and teachers. However, as this paper will discuss, the authors seem to ignore some fundamental flaws in the leadership model of U.S. government funded MSP projects, which create issues in initiatives such as ISU’s STEM Education and Leadership Program from their outset through preset restrictions and regulations, and this can hinder the intended promotion of STEM careers.

description: The soft-gamma repeater Swift J1818.0$-$1607 is only the fifth magnetar found to exhibit pulsed radio emission. Using the Ultra-Wideband Low receiver system of the Parkes radio telescope, we conducted a 3 h observation of Swift J1818.0$-$1607. Folding the data at a rotation period of $P = 1.363$ s, we obtained wideband polarization profiles and flux density measurements covering radio frequencies between 704-4032 MHz. After measuring, and then correcting for the pulsar's rotation measure of $1442.0 \pm 0.2$ rad m$^{-2}$, we find the radio profile is between 80-100 per cent linearly polarized across the wide observing band, with a small amount of depolarization at low frequencies that we ascribe to scatter broadening. We also measure a steep spectral index of $α= -2.26^{+0.02}_{-0.03}$ across our large frequency range, a significant deviation from the flat or inverted spectra often associated with radio-loud magnetars. The steep spectrum and temporal rise in flux density bears some resemblance to the behaviour of the magnetar-like, rotation-powered pulsar PSR J1119$-$6127. This leads us to speculate that Swift J1818.0$-$1607 may represent an additional link between rotation-powered pulsars and magnetars.

description: Die Erlebnispädagogik ist eine eher junge Profession, die sich in den letzten Jahren stark entwickelt hat. Insbesondere auch in der Zusammenarbeit mit Kindern und Jugendlichen bietet die Erlebnispädagogik unzählige Methoden und Ansätze. Durch die Erlebnispädagogik können Kinder und Jugendliche Erfahrungen in der Natur sammeln, was sich wiederum positiv auf die Persönlichkeitsentwicklung auswirken kann. Die Integration von erlebnispädagogischen Angeboten in die Schulsozialarbeit und somit im Kontext der Schule ist bislang noch nicht weit verbreitet. Aufgrund dessen wurde im Rahmen dieser Bachelor-Arbeit eine Forschung in Form von Expert*inneninterviews durchgeführt. Die Forschung, verknüpft mit der bestehenden Literatur, zeigt auf, ob und wie die Integration von erlebnispädagogischen Angeboten in die Schulsozialarbeit möglich ist und wie diese Angebote insbesondere auch Schüler*innen mit herausfordernden Verhaltensweisen unterstützen können. Aus der Forschung wird ersichtlich, dass erlebnispädagogische Angebote eine grosse Chance für die Schulsozialarbeit und das gesamte schulische System darstellen.

description: To contribute to the reduction of malnutrition in Timor-Leste, particularly for women of reproductive age and children aged 6–23 months, the To’os ba Moris Di’ak / Farming for Prosperity program (TOMAK) run by the Dept of Foreign Affairs & Trade, applies a nutrition-sensitive agriculture (NSA) approach. This approach seeks to strengthen the contribution of agriculture to improving nutrition outcomes. Agriculture is nutrition-sensitive when it addresses the underlying causes of malnutrition. The program focuses on supplyside and demand-side issues surrounding nutrition. On the supply side, TOMAK aims to improve supply and year-round access to nutritious foods – particularly for women and children. This includes building NSA knowledge and skills at institutional as well as community level, and developing gender-equitable decision-making in households. On the demand side, TOMAK is influencing awareness of and demand for nutritious food at the household level through social behaviour change (SBC) communication, to maximise consumption of nutritious foods. To create this change, TOMAK works with and through partners, including NGOs and government. The approach has allowed TOMAK to build on and expand the work of the nongovernment organisations Mercy Corps, Catholic Relief Services and World Vision and their local partners, as well as providing opportunities to trial new approaches to NSA and SBC in Timor-Leste. TOMAK works closely with the Ministry of Agriculture and Fisheries and Ministry of Health, taking a multi-sectoral approach to augment the Government of Timor-Leste’s existing nutrition work and develop increased NSA capacity for delivery in municipalities.

description: An efficient electro-optical modulation has been demonstrated here by using an edge plasmon mode specific for the hybrid plasmonic waveguide. Our approach addresses a major obstacle of the integrated microwave photonics caused by the polarization constraints of both active and passive components. In addition to sub-wavelength confinement, typical for surface plasmon polaritons, the edge plasmon modes enable exact matching of the polarization requirements for silicon based input/output grating couplers, waveguides and electro-optical modulators. A concept of the hybrid waveguide, implemented in a sandwich-like structure, implies a coupling of propagating plasmon modes with a waveguide mode. The vertically arranged sandwich includes a thin layer of epsilon-near-zero material (indium tin oxide) providing an efficient modulation at small length scales. Employed edge plasmons possess a mixed polarization state and can be excited with horizontally polarized waveguide modes. It allows the resulting modulator to work directly with efficient grating couplers and avoid using bulky and lossy polarization converters. A 3D optical model based on Maxwell equations combined with drift-diffusion semiconductor equations is developed. Numerically heavy computations involving the optimization of materials and geometry have been performed. Effective modes, stationary state field distribution, an extinction coefficient, optical losses and charge transport properties are computed and analyzed. In addition to the polarization matching, the advantages of the proposed model include the compact planar geometry of the silicon waveguide, reduced active electric resistance R and a relatively simple design, attractive for experimental realization.

description: Traditional models of coronal oscillations rely on modelling the coronal structures that support them as compact cylindrical waveguides. Recently, an alternative model of the structure of the corona has been proposed, where the thin strand-like coronal loops observable in the EUV emission are a result of line-of-sight integration of warps in more complex coronal structures, referred to as the coronal veil model. We extend the implications of the coronal veil model of the solar corona to models of coronal oscillations. Using the convection-zone-to-corona simulations with the radiation-magnetohydrodynamics code Bifrost, we analysed the structure of the self-consistently formed simulated corona. We focus on the spatial variability of the volumetric emissivity of the Fe IX 171.073 Å EUV line, and on the variability of the Alfvén speed, which captures the density and magnetic structuring of the simulated corona. We traced features associated with large magnitudes of the Alfvén speed gradient, which are the most likely to trap MHD waves and act as coronal waveguides, and looked for the correspondence with emitting regions which appear as strand-like loops in line-of-sight-integrated EUV emission. The waveguide filling factors corresponding to the fraction of the waveguides filled with plasma emitting in the given EUV wavelength range from 0.09 to 0.44. This suggests that we can observe only a small fraction of the waveguide. Similarly, the projected waveguide widths in the plane of the sky are several times larger than the widths of the apparent loops observable in EUV. We conclude that the 'coronal veil' structure is model-independent. As a result, we find a lack of straightforward correspondence between a peak in the integrated emission profile which constitutes an apparent coronal loop and regions of plasma bound by a large Alfvén speed gradient acting as waveguides.

description: Fish plays a vital role in the nutritional quality of diets in Bangladesh, especially for the poor. It is also inextricably linked to the culture of Bangladeshi people and supports the livelihoods of more than 17 million people. Nutrient composition analysis has shown wide variability in the nutritional value of different fish species, with small indigenous fish species (SIS) being particularly rich sources of iron, zinc, calcium, vitamin A, vitamin B12 and other micronutrients, in comparison to commonly farmed species. Given widespread malnutrition issues in Bangladesh, there is significant opportunity for fish to play a greater role in contributing to improved food and nutrition security. WorldFish and partners have developed a package of approaches to maximise the benefit of fisheries and aquaculture for nutrition outcomes among vulnerable groups through nutritionsensitive fish agri-food systems. These involve inclusion of nutrient-rich SIS in pond polyculture systems, enhanced stocking of SIS in wetlands, integrated vegetable production on pond dykes and in homestead gardens, simple processing of fish to improve suitability for consumption by infants, and engaging women in fish harvesting to promote frequent consumption of SIS by women and children. These activities are supported by broader approaches including transforming norms, attitudes and practices around gender equity, and social behaviour change communication for improved nutrition and hygiene practices. The integrated and multi-component nature of these approaches has shown numerous benefits for nutrition, gender equity, income and livelihoods. Nutrition-sensitive approaches to fish agri-food systems are central to contributing to the Sustainable Development Goals in Bangladesh and beyond.

Using TEXES at the NASA IRTF 3m, we are midway through a survey of roughly 30 pre-main-sequence stars. To date, detected lines are all resolved, generally with FWHM<10 km/s. Preliminary analysis suggests the gas temperatures are between 400 and 800 K. From the work so far, we conclude that high spectral and spatial resolution are critical to the investigation of H2 in disks.

description: Micronutrient deficiencies are among the most serious health issues facing billions of people in developing countries of Africa, Asia and Latin America. Rice and wheat provide a significant proportion of dietary energy in these countries, yet people who consume large quantities of cereals often suffer from ‘hidden hunger’ due to low concentrations of iron, zinc and provitamin A in the grain. Human iron deficiency is the most common nutritional disorder in the world, affecting more than two billion people, with symptoms ranging from poor mental development in children and depressed immune function, to iron deficiency anaemia. The development of iron enriched crops – a process commonly referred to as iron biofortification – has emerged as a highly economic and sustainable approach towards increasing iron intakes in developing countries at no additional cost to growers and food manufacturers. We have used genetic engineering to produce rice and wheat plants that are more effective at mining soil for iron and transporting iron to grain. These iron-biofortified plants contain significantly increased iron concentrations in edible grain tissues. They yield normally in multi-location field trials, and have high iron bioavailability as indicated by cell culture assays. Whilst the first release of iron-biofortified rice will likely occur in Bangladesh, subsequent adoption of iron-biofortified rice in West and Central Africa could contribute to major reductions in human iron deficiency. Iron-biofortified wheat is likely to have similar impact if adopted in wheat growing regions of North Africa.

description: Sparse sensor array selection arises in many engineering applications, where it is imperative to obtain maximum spatial resolution from a limited number of array elements. Recent research shows that computational complexity of array selection is reduced by replacing the conventional optimization and greedy search methods with a deep learning network. However, in practice, sufficient and well-calibrated labeled training data are unavailable and, more so, for arbitrary array configurations. To address this, we adopt a deep transfer learning (TL) approach, wherein we train a deep convolutional neural network (CNN) with data of a source sensor array for which calibrated data are readily available and reuse this pre-trained CNN for a different, data-insufficient target array geometry to perform sparse array selection. Numerical experiments with uniform rectangular and circular arrays demonstrate enhanced performance of TL-CNN on the target model than the CNN trained with insufficient data from the same model. In particular, our TL framework provides approximately 20% higher sensor selection accuracy and 10% improvement in the direction-of-arrival estimation error.

description: Food is fuelling several of the major global challenges of our time. Current food systems fail one in two people worldwide and poor diets are now the leading risk factor for disease, globally. Food systems also represent a significant driver of environmental degradation. Yet because food cross-cuts the major health, environmental and sustainable development challenges of today, bending the curve of unhealthy, unsustainable food provides one of the greatest opportunities to achieve our Global Goals. Mounting research demonstrates the benefits of transforming our food systems, but a crucial next step is translating this research into action. This talk outlines some of the major linkages between food, people and the planet, and presents the coming EAT–Lancet Commission on Healthy Diets from Sustainable Food Systems as well as the Lancet Series on the Double Burden of Malnutrition. The former will synthesise the best available science to define what constitutes a healthy diet globally and what sustainable food production looks like that preserves functional ecosystems, and the latter outlines the important opportunities for integrated action on malnutrition in all its forms.
Über das Verständnis der Desymmetrisierung von Phosphinoboranen für die effiziente Synthese katalytisch relevanter P-stereogener Liganden

description: P-stereogene Phosphane zählen zu den bedeutendsten Liganden in der asymmetrischen Übergangsmetallkatalyse. Die Entwicklung synthetisch effizienter Zugänge ist eine wichtige Herausforderung aktueller Forschung. In der vorliegenden Arbeit wurde der einfach zugängliche Ligand (R,R) TMCDA zur Darstellung von P stereogenen Synthesebausteinen genutzt. Über die kristallisationsinduzierte dynamische Racematspaltung (CIDR) von lithiierten Phosphinoboranen gelang es, hochangereicherte Produkte mit Enantiomerenverhältnissen bis zu 98:2 und Ausbeuten bis zu 80% zu erhalten. Die durchgeführten Arbeiten demonstrieren die präparative Nutzbarkeit der untersuchten Methode und legen das Fundament für die Entwicklung weiterer wertvoller chiraler Synthesebausteine. Die synthetischen Anwendungen wurden durch Untersuchungen zu Isomerisierungsmechanismen metallierter Phosphinoborane ergänzt. Durch die Kombination von Experimenten, quantenchemischen Berechnungen sowie strukturellen Untersuchungen konnten diese näher beleuchtet werden. Isotopenmarkierungexperimente zeigen, dass α lithiierte Dimethylphosphinoborane über einen intermolekularen Protonentransfer von der Ausgangsverbindung isomerisieren können. Im Falle lithiierter sekundärer Phosphidoborane stellt die pyramidale Inversion am Phosphorzentrum ein plausibles mechanistisches Szenario dar. Beide Prozess sind für die dynamische Racematspaltung der P stereogenen Bausteine notwendig, jedoch im Zuge der synthetischen Anwendung unerwünscht, da sie mit einem Verlust an optischer Reinheit einhergehen. Glücklicherweise liegen die Energiebarrieren in Bereichen, die eine Steuerung über die Reaktionstemperatur erlauben: Bei tiefen Temperaturen werden die Umwandlungen unterbunden und können bei höheren Temperaturen für die stereochemische Anreicherung im Zuge der CIDR gezielt aktiviert werden. Insgesamt leistet diese Arbeit einen Beitrag zur Erschließung von effizienten Zugängen zu chiralen Synthesebausteinen und ergänzt das Verständnis der Stereochemie des Phosphors.

description: On 25 September 2015, the 193 members of the United Nations General Assembly unanimously agreed to ‘End Hunger’ by 2030 through their agreement on the 2030 Agenda on Sustainable Development. Under Sustainable Development Goal (SDG) 2, the world’s leaders agreed not only to ‘End Hunger’, but to ‘Achieve Food Security and Improved Nutrition, and Promote Sustainable Agriculture’ – an extraordinarily ambitious agenda of eight targets and 14 indicators encompassing hunger, agriculture, environment, nutrition, trade and investment. Approaching three years into the 2030 Agenda, an impressively large number of governments, international agencies, NGOs, businesses and universities have embraced SDG 2, along with several other complementary SDGs, as a framework for action towards achieving a healthier and more sustainable global food system. However, delivering results through policies and programs is proving more challenging. In presenting their Voluntary National Reviews to the United Nations, most countries have reported on their aspirational plans and good intent. Results at scale are few and far between. In this overview, I will draw on personal experience from four countries (Cambodia, Malawi, Timor-Leste and Tajikistan) to identify strategic operational and design lessons that can inform a more effective response to SDG 2. My conclusion is that SDG 2 is by and large achievable but more likely by 2040 or 2050, rather than 2030. Across all targets, we have the knowledge and the financial resources to enable an unprecedented positive transformation of our global food system. All that is required is genuine, sustained political commitment and creative implementation strategies.

description: We present the results of a molecular survey of long period comets C/2021 A1 (Leonard) and C/2022 E3 (ZTF). Comet C/2021 A1 was observed with the IRAM 30-m radio telescope in November-December 2021 before perihelion when it was closest to the Earth. We observed C/2022 E3 in January-February 2023 with the Odin 1-m space telescope and IRAM 30-m, shortly after its perihelion, and when it was closest to the Earth. Snapshots were obtained during 12-16 November 2021 period for comet C/2021 A1. Spectral surveys were undertaken over the 8-13 December 2021 period for comet C/2021 A1 (8, 16, and 61 GHz bandwidth in the 3 mm, 2 mm, and 1 mm window) and over the 3-7 February 2023 period for comet C/2022 E3 (25 and 61 GHz at 2 and 1mm). We report detections of 14 molecular species (HCN, HNC, CH3CN, HNCO, NH2CHO, CH3OH, H2CO, HCOOH, CH3CHO, H2S, CS, OCS, C2H5OH and aGg-(CH2OH)2 ) in both comets plus HC3N and CH2OHCHO marginally detected in C/2021 A1 and CO and H2O (with Odin detected in C/2022 E3. The spatial distribution of several species is investigated. Significant upper limits on the abundances of other molecules and isotopic ratios are also presented. The activity of comet C/2021 A1 did not vary significantly between 13 November and 13 December 2021. Short-term variability in the outgassing of comet C/2022 E3 on the order of +-20% is present and possibly linked to its 8h rotation period. Both comets exhibit rather low abundances relative to water for volatiles species such as CO (< 2%) and H2S (0.15%). Methanol is also rather depleted in comet C/2021 A1 (0.9%). Following their revised photo-destruction rates, HNCO and HCOOH abundances in comets have been reevaluated. Both molecules are relatively enriched in these two comets (0.2% relative to water). We cannot exclude that these species could be produced by the dissociation of ammonium salts.

description: Transport through molecular devices with strong coupling to a single vibrational mode is considered in the case where the vibration is damped by coupling to the environment. We focus on the weak tunneling limit, for which a rate equation approach is valid. The role of the environment can be characterized by a frictional damping term $\mysig(ω)$ and corresponding frequency shift. We consider a molecule that is attached to a substrate, leading to frequency-dependent frictional damping of the single oscillator mode of the molecule, and compare it to a reference model with frequency-independent damping featuring a constant quality factor $Q$. For large values of $Q$, the transport is governed by tunneling between displaced oscillator states giving rise to the well-known series of the Frank-Condon steps, while at small $Q$, there is a crossover to the classical regime with an energy gap given by the classical displacement energy. Using realistic values for the elastic properties of the substrate and the size of the molecule, we calculate $I$-$V$ curves and find qualitative agreement between our theory and recent experiments on $C_{60}$ single-molecule devices.
