description: While the galactic density wave theory is over 50 years old and well known in science, whether it fits our own Milky Way disk has been difficult to say. Here we show a substructure inside the spiral arms. This substructure is reversing with respect to the Galactic Meridian (longitude zero), and crosscuts of the arms at negative longitudes appear as mirror images of crosscuts of the arms at positive longitudes. Four lanes are delineated: mid-arm (extended 12CO gas at mid arm, HI atoms), in-between offset by about 100 pc (synchrotron, radio recombination lines), in between offset by about 200 pc (masers, colder dust), and inner edge (hotter dust seen in Mid-IR and Near-IR).

Dynamics of mesenchymal stromal cell potency during ex vivo bioreactor therapy
Creators: name: Doshi, Aneesha
Publisher: name: No Publisher Supplied
Year: 2022

description: Mesenchymal stromal cells have become a candidate for cell therapy due to potent immunomodulatory properties exhibited in their secretome. However, they have shown limited clinical success due to issues of dosing and persistence when administered in vivo. A scalable hollow fiber bioreactor device has been created to deliver MSC therapeutics in an ex vivo manner. The potency and behavior of MSCs in this bioreactor can be explored via a dynamic perfusion system, collecting the MSC secretome in periodic fractions and comparing the MSC behavior at different time points and in response to a variety of factors. Herein, a study was designed to determine the dynamic potency of the MSC secretome using this device and characterize their secreted factors when cocultured with immune cells. Three studies were designed to characterize the dynamic baseline MSC behavior, determine how MSCs behave in a model of an inflamed patient, and understand the effect of prelicensing MSCs on their dynamic potency. Results indicate an ideal dosing time of 24 hours and significant benefits when prelicensing MSCs used in the device. Ultimately, this research can be translated clinically to maximize the potency of the MSC therapy, minimize side effects, and allow greater control for the duration of the ex vivo bioreactor therapy.
An overview of issues and lessons learnt working with the ACES ALMA Large Program

Year: 2024

description: The ALMA Cycle 8 large project ACES (ALMA Central Molecular Zone Exploration Survey) aims to map the entire Centre of the Milky Way with unprecedented spatial dynamic range in a number of lines and continuum in ALMA Band 3. The final cubes produced as part of this project will contain over 5,000 individual ALMA pointings, or around 500,000 individual beams, across more than 15,000 channels (equating to terabytes in size per cube). These data are extraordinary at present, but they may become somewhat routine after the ALMA Wideband Sensitivity Upgrade. During this talk, I will give a brief introduction to the large program and then discuss the issues we have encountered, along with lessons learnt, during the reduction and analysis of this dataset.
Bound-bound transitions in the emission spectra of Ba$^{+}$--He excimer

description: We present an experimental and theoretical study of the emission and absorption spectra of the Ba$^{+}$ ions and Ba$^{+\ast}$He excimer quasimolecules in the cryogenic Ba--He plasma. We observe several new spectral features in the emission spectrum which we assign to the electronic transitions between bound states of the excimer correlating to the 6$^{2}P_{3/2}$ and 5$^{2}D_{3/2,5/2}$ states of Ba$^{+}$. The resulting Ba$^{+}$(5$^{2}D_{J}$)He is a metastable electronically excited complex with orbital angular momentum $L$=2, thus expanding the family of known metal--helium quasimolecules. It might be suitable for high-resolution spectroscopic studies and for the search for new polyatomic exciplex structures.

description: Dynamic kinetic resolution (DKR) of racemic starting material is a promising route to optically pure (S)-benzoin (2-hydroxy-1,2-di(phenyl)ethanone) and various symmetrical and unsymmetrical derivatives thereof. Here, this route was advanced towards technical scale synthesis using the basic (rac)-benzoin as model system. The reaction employed stereoselective transesterification of (S)-benzoin with lipase TL® from Pseudomonas stutzeri and racemization of (R)-benzoin with Metal-TUD-1, a metal-associated acidic meso-porous silicate, in pure organic solvent. Enzyme performance was improved by immobilization on Accurel MP1001 (yielding Acc-LipTL), and Zr-TUD-1 (Si/Zr = 25) was identified as most effective racemization catalyst. Compatibility in solvent and temperature dependency enabled performance in only one pot. DKR in toluene at 50 °C yielded conversions above 98% and an ee of >97% in only five hours. Stability of Acc-LipTL was further improved with polyethylene imine and the reaction system was then reused in five cycles, retaining a conversion of >99% and a product-ee of >98%. On a semi-preparative scale, the isolated yield of enantiopure (S)-benzoin butyrate was >98%. Thus, the system provides a good basis for synthesis of enantiopure benzoin, and potentially a broader range of aromatic α-hydroxy ketones.

description: Impairment of vascular pathways of cerebral β-amyloid (Aβ) elimination contributes to Alzheimer disease (AD). Vascular damage is commonly associated with diabetes. Here we show in human tissues and AD-model rats that bloodborne islet amyloid polypeptide (amylin) secreted from the pancreas perturbs cerebral Aβ clearance. Blood amylin concentrations are higher in AD than in cognitively unaffected persons. Amyloid-forming amylin accumulates in circulating monocytes and co-deposits with Aβ within the brain microvasculature, possibly involving inflammation. In rats, pancreatic expression of amyloid-forming human amylin indeed induces cerebrovascular inflammation and amylin-Aβ co-deposits. LRP1-mediated Aβ transport across the blood-brain barrier and Aβ clearance through interstitial fluid drainage along vascular walls are impaired, as indicated by Aβ deposition in perivascular spaces. At the molecular level, cerebrovascular amylin deposits alter immune and hypoxia-related brain gene expression. These converging data from humans and laboratory animals suggest that altering bloodborne amylin could potentially reduce cerebrovascular amylin deposits and Aβ pathology.

description: The upgrade of the ALMA Wideband Single-Channel Correlator (WSU) is currently underway, making it an opportune time to explore additional possibilities and technologies for further enhancing ALMA's capabilities. In this discussion, we will explore a broad range of potential technologies that could be implemented in the medium to long term, looking toward the years 2040 and beyond. These technologies include extended baselines, focal plane arrays, phased array feeds, additional antennas, and the construction of a large single-dish submillimeter telescope. Additionally, we will consider the technological advancements necessary to realize these goals.

description: We perform a detailed analysis of the behavior of coherent and squeezed states undergoing time evolution. We calculate time dependence of expectation values of position and momentum in coherent and squeezed states (which can be interpreted as quantum trajectories in coherent and squeezed states) and examine how coherence and squeezing is affected during time development, calculating time dependence of position and momentum uncertainty. We focus our investigations on two quantum systems. First we consider quantum linear system with Hamiltonian quadratic in $q$ and $p$ variables. As the second system we consider the simplest quantum nonlinear system with Hamiltonian quartic in $q$ and $p$ variables. We calculate the explicit formulas for the time development of expectation values and uncertainties of position and momentum in an initial coherent state.

Cosmic Rays at the ALMA sites: impact on thin gate-size electronics and radiation exposure
Creators: name: Baudry, Alain

Publisher: name: Zenodo
Year: 2024

description: Generation in the Earth's atmosphere of multiple secondary Cosmic Rays (CRs) impacts the (ultra)thin gate size electronics embedded in many modules of the ALMA Wideband Sensitivity Upgrade (WSU) project. Around 5.6x10$^{-5}$ Single Event Upsets (SEUs) per device and hour have already been observed in the FPGAs of the current correlator. Despite advances in integration designs and configuration integrity testing in the latest FPGAs, Single Event Effects (SEEs) are expected to appear in devices that format the digital samples at the AOS antennas and, later, in the WSU correlator at the OSF. We have used our multi-applications numerical platforms to successfully compare the Software Error Rate (SER) observed in the current correlator with our simulations to extract the neutrons (dominant risk) and protons cross-sections and SER at the ALMA sites. A first, rough prediction at the level of $\sim$10 events per month in the 226 Agilex FPGAS (10-nm) of the WSU correlator could be closely examined with our numerical tools, including the impact of extreme Solar events. Biological cells are also impacted by the CRs. We evaluate the yearly dose exposure to be $\sim$4.8 mSv (AOS) and $\sim$1.8 mSv (OSF) with additional ambient dose up to $\sim$1 mSv (Solar events). We propose to deploy at the ALMA sites a compact, low power consumption, remotely operated neutron spectrometer similar to spectrometers used in Antarctica and on top of high mountains for a precise SEE analysis and space weather monitoring.

description: Theorists and advocates of "remixing" have suggested that appropriation can act as a pathway for learning. We test this theory quantitatively using data from more than 2.4 million multimedia programming projects shared by more than 1 million users in the Scratch online community. First, we show that users who remix more often have larger repertoires of programming commands even after controlling for the numbers of projects and amount of code shared. Second, we show that exposure to computational thinking concepts through remixing is associated with increased likelihood of using those concepts. Our results support theories that young people learn through remixing, and have important implications for designers of social computing systems.

description: Diese Arbeit befasst sich mit den Einsatz von Techniken der automatisierten Beweisführung (“automated theorem proving”, kurz ATP) im Bezug auf zwei Systeme des natürlichen Schließens für die klassische Aussagenlogik. Einerseits handelt es sich dabei um das weithin bekannte assertive Beweissystem nach Gentzen und Jaśkowski, andererseits um ein dazu komplementäres Verwerfungssystem nach Tamminga. Den Ansätzen folgend, die sich in der Literatur bei bereits existierenden ATPs für natürliches Schließen finden, erstellen wir zuerst eine Variante des Verwerfungssystems für die ein schwaches Normalisierungstheorem gilt, gefolgt von Varianten beider Systeme mit denen die Schleifenfreiheit der Beweise sichergestellt ist. Weiters implementieren und evaluieren wir Hermes, einen Prolog-ATP der parallel nach Assertions- und Verwerfungsbeweisen sucht. Aus unseren Beobachtungen geht hervor, dass sich mit einem solchen Programm durchaus Beweise generieren lassen, die den von Menschen erstellten ähneln, jedoch ist die Performanz insbesondere beim Generieren von Verwerfungsbeweisen nicht optimal, da gewisse gescheiterte Suchpfade intensives Backtracking erforderlich machen.
description: We investigate the use of automated theorem proving (ATP) techniques with regards to two natural deduction systems for classical propositional logic. One is the well-known assertional system following Gentzen and Jaśkowski, and the other is a refutational system due to Tamminga. Based on the approaches used by existing ATPs for natural deduction in the literature, we establish first a variant of the refutational system for which a weak normalisation theorem holds, and then variants of both systems that ensure loop-free derivations. We further implement and evaluate Hermes, a Prolog-based ATP that searches for assertional and refutational natural deduction derivations in parallel. Our observations show that this program is capable of producing remarkably human-like derivations for both valid and refutable formulas, but its performance, particularly in the refutational component, is not optimal due to the intensive backtracking required on certain failed derivation paths.

description: Group for Advanced Receiver Development (GARD) at Chalmers University actively participates in development of instrumentation for ALMA, e.g., ALMA Band 5 and, recently, ALMA Band 2. GARD involved in the ESO supported ALMA Development Study, by running project ``ALMA Band 6 and 7 Cold Cartridge Demonstrator''. We would like to present recent progress of this project work towards SIS mixer receiver covering 210-375 GHz RF band and having 4-20 GHz IF band. We plan to present results of development and tests of various components for such receiver. We show the results on the development of wideband optics and corrugated feed for such broadband receiver that has key importance as it would ensure feasibility of such receiver effective coupling to the antenna. We will present results of the development of the broadband OMT that is known using single feed for both polarizations and providing superior beam alignment on sky between the two polarization in the ALMA receivers as compared to polarizing grids. We will show results of the development of the 2SB mixer components and measurement results of the DSB mixer chip. Finally, we will present proposed 3D CAD model for such receiver in the ALMA cartridge environment.

The perturbative expansion is precise as the coefficients are available up to $O(α_s^4)$. We employ $2+1$-flavor lattice ensembles at three lattice spacings in the range 0.044--0.080~fm.

description: We explore the impact of a cosmic ray (CR) background generated by supernova explosions from the first stars on star-forming metal-free gas in a minihalo at $z\sim25$. Starting from cosmological initial conditions, we use the smoothed particle hydrodynamics code GADGET-2 to follow gas collapsing under the influence of a CR background up to densities of $n=10^{12}\,{\rm cm}^{-3}$, at which point we form sink particles. Using a suite of simulations with two sets of initial conditions and employing a range of CR background models, we follow each simulation for $5000\,$yr after the first sink forms. CRs both heat and ionise the gas, boosting ${\rm H}_2$ formation. Additional ${\rm H}_2$ enhances the cooling efficiency of the gas, allowing it to fulfil the Rees-Ostriker criterion sooner and expediting the collapse, such that each simulation reaches high densities at a different epoch. As it exits the loitering phase, the thermodynamic path of the collapsing gas converges to that seen in the absence of any CR background. By the time the gas approaches sink formation densities, the thermodynamic state of the gas is thus remarkably similar across all simulations. This leads to a robust characteristic mass that is largely independent of the CR background, of order $\sim$ a few $\times10\,{\rm M}_{\odot}$ even as the CR background strength varies by five orders of magnitude.

description: The ALMACAL survey, a comprehensive study of ALMA calibrator data, has been pivotal in advancing our scientific understanding in many areas. This talk will review the major milestones achieved, with a particular focus on the molecular gas evolution traceable by CO emission within the calibrator fields. I will present new results of the blind CO search using all available calibrator data until May 2022 in Band 3 and 6, accumulating about 540 hours. The upcoming ALMA Wideband Sensitivity upgrade, promising a fourfold increase in bandwidth, will significantly enhance the frequency coverage of each calibrator data set. I will discuss the impact of these upgrades on the ALMACAL survey in terms of the improved emission-line sensitivity and much increased line search efficiency of ALMA, which will revolutionize our understanding of the cosmic evolution of cold gas.

description: A code over a finite alphabet is called locally recoverable (LRC code) if every symbol in the encoding is a function of a small number (at most $r$) other symbols of the codeword. In this paper we introduce a construction of LRC codes on algebraic curves, extending a recent construction of Reed-Solomon like codes with locality. We treat the following situations: local recovery of a single erasure, local recovery of multiple erasures, and codes with several disjoint recovery sets for every coordinate (the {\em availability problem}). For each of these three problems we describe a general construction of codes on curves and construct several families of LRC codes. We also describe a construction of codes with availability that relies on automorphism groups of curves.

description: We assess current experimental constraints on the bi-doublet + singlet model of top compositeness previously proposed in the literature. This model extends the standard model's spectrum by adding a custodially-embedded vector-like electroweak bi-doublet of quarks and a vector-like electroweak singlet quark. While either of those states alone would produce a model in tension with constraints from precision electroweak data, in combination they can produce a viable model. We show that current precision electroweak data, in the wake of the Higgs discovery, accommodate the model and we explore the impact of direct collider searches for the partners of the top quark.

Unveiling the Cosmic History of Gas and Dust with Broad ALMA Bandwidths
Creators: name: Boogaard, Leindert
Publisher: name: Zenodo
Year: 2024

description: In search of our Cosmic Origins, molecular deep fields have provided an unprecedented view on the evolution of the cosmic molecular gas through time.  These spectral-scan mosaics, conducted on the worlds largest interferometers (e.g., the 200h ALMA/ASPECS large program), map the total gas and dust content of the universe and have, in the last decade, revealed its evolution similar to the cosmic density of star formation for the first time.  Yet, it has also become clear that further progress is limited with current facilities, unless significantly larger time investments are made.  The 2-4x increase in total bandwidth from ALMA Wideband Sensitivity Upgrade is an critical development in this regard: as the efficiency of spectral scan surveys scales linearly with bandwidth, a 4x increase in bandwidth will be instrumental to enable the next-generation of molecular deep fields and spectral scan surveys.  The large instantaneous bandwidths will also critically improve the dust continuum sensitivity. For both nearby and distant galaxies, a 4x larger bandwidth will enable a near complete spectroscopic inventory in a single tuning.  Including the overall gains in sensitivity from upgrading the ALMA signal-chain, the WSU will greatly enhance the efficiency ALMA in unveiling gas and dust in galaxies through cosmic time.

description: As Open Science reaches its most world widespread version yet, Universidad Nacional in Costa Rica has launched the Strategy of the National University in Open Science. This strategy serves as an institutional policy that organizes our community’s efforts towards knowledge democratization and is consistent with the Diamond Open Access Model, the Global South Open Science Model and UNESCO’s Recommendation on Open Science (2021). The strategy leans on the first efforts led by the university’s open access journals, the Institutional Academic Heritage Conservation Policy, and the Institutional Policy for the Use of Free Software and considers a 5 year period (2023-2027) for implementation on a community wide basis. Involved in a public funding cycle, state universities like UNA, are clear about their responsibility to transform the knowledge they generate into direct benefits for the society that finances them. Therefore, the strategy’s main goal is to adopt good practices of Open Science and apply them transversally in the substantive activities of the university (teaching, research, social projection, and production), based on the monitoring of activities associated with the pillars of Open Science. The strategy includes the following pillars: Open Access; Research Data; Open Science Tools and Technology; Open Access Assessment; Open Innovation; Citizen Science, and Open Science International Policies, Statements and Guidelines. Its construction involved the efforts of the Vice-Rectory of Research personnel, journal editors, librarians, IT Specialists, and legal advisors teamed up as the UNA-Ciencia Abierta working network. The main activities of the strategy consider: The promotion of Open Science practices and competencies. The adoption of standards and other tools that allow the university community to find, access, reuse and combine knowledge. Place sustainable and interoperable infrastructures that allow the open exchange of knowledge. UNA emphasizes the participative nature of the initiatives, such as this strategy, that involve different knowledge in a constructive manner in accordance with the collective benefit and the institutional purposes, therefore other working areas can be considered in the near future The document is being published for adoption in 2023, specific and more detailed actions will be available at the published version.

Revealing the volatile planet formation reservoir with ALMA spectral line surveys
Creators: name: Booth, Alice
Publisher: name: Zenodo
Year: 2024

description: Protoplanetary disks host the dust, gas and ice that will form new solar systems. Therefore, it is key to understand disk chemistry when considering the composition of planets and the potential habitability of these systems. Due to the line sensitivity of ALMA, we have now detected many rare isotopologues and complex organic molecules in disks for the first time. In particular, serendipitous line detections and unbiased line surveys have been key in revealing these new molecules. In this talk, I will summarize the new detections from ALMA highlighting the results from line surveys of disks around intermediate-mass stars where we can access the thermal sublimation of H2O and organic-rich ices. I will show how these disks are our best opportunity to recover the total volatile reservoir during the epoch of planet formation. In addition, I will share some first results from the ongoing unbiased 124 GHz line survey of 40 gas-rich disks with Submillimeter Array (SMA-SPEC). The WSU will revolutionize disk chemistry observations with the increase in survey speed and the observable bandwidth. This promises the detection of key isotopologues and pre-biotic molecules in disks that will enable us to fill the key gap in following the journey of volatiles from dark clouds and protostars all the way through to planets and comets.

description: We do a search for topological insulators which are associated with ferromagnetic ordering and show anomalous quantum Hall effect, among transition metal oxide superlattices taking the parent compounds as LaAlO3 and SrTiO3. Among the various superlattices which are studied here, (LaAlO3)10/(LaOsO3)2 exhibits a ferromagnetic ground state with a topologically non-trivial energy gap when a spin-orbit interaction is turned on. The study of transverse conductivity shows that the system has quantized Hall conductivity inside the topological energy gap without applying any external magnetic field. The ferromagnetic order parameters and the ordering temperature (Tc) have been estimated by taking a simple Heisenberg model of ferromagnetism.

description: Exploiting the homogeneous structure of a wedge in the complex plane, we compute the spectrum of the anti-linear Ahlfors-Beurling transform acting on the associated Bergman space. Consequently, the similarity equivalence between the Ahlfors-Beurling transform and the Neumann-Poincare operator provides the spectrum of the latter integral operator on a wedge. A localization technique and conformal mapping lead to the first complete description of the essential spectrum of the Neumann-Poincare operator on a planar domain with corners, with respect to the energy norm of the associated harmonic field.

description: We consider linear cyclic codes with the locality property, or locally recoverable codes (LRC codes). A family of LRC codes that generalize the classical construction of Reed-Solomon codes was constructed in a recent paper by I. Tamo and A. Barg (IEEE Trans. Inform. Theory, no. 8, 2014). In this paper we focus on optimal cyclic codes that arise from this construction. We give a characterization of these codes in terms of their zeros, and observe that there are many equivalent ways of constructing optimal cyclic LRC codes over a given field. We also study subfield subcodes of cyclic LRC codes (BCH-like LRC codes) and establish several results about their locality and minimum distance. The locality parameter of a cyclic code is related to the dual distance of this code, and we phrase our results in terms of upper bounds on the dual distance.

description: As the dissemination of knowledge and scientific influence are structuring values of the université Paris Nanterre in France, the institution adopted an ambitious open science policy in 2021. The institution's strategy has acted a very strong awareness of the necessary support and reinforcement to be given to the pillar infrastructures of open science. ** Nanterres' vision of open science The challenge is to develop an original political vision for Nanterre, one that reflects its human and humanistic values and realities. The institutions's open science charter and its roadmap are structured by strong commitments in favour of the development of open science, particularly in SSH, which give rise to the implementation of concrete actions. Among these axes, there is one specifically dedicated to the support of open science infrastructures. This support often takes two complementary forms: financial support for structures that often have a fragile economic model; participation in the governance of organisations that are building the future of academic research. ** Method, criteria and support modalities This poster focuses on how this specific provision of support and participation in the governance of open science infrastructures operated by the Library on behalf of the institution has been conceived and built in order to fit in with the university's open science strategy and in complementarity with its participation in national and international networks related to open science issues. This have been beneficial to the open science pillar infrastructures by providing funding and promoting strong and sound governance in the open science ecosystem, to the university in terms of strengthening its positioning and its internal dynamics in favour of open science, and to the library in terms of developing innovative, forward-looking and high value-added services that promote access to research results. ** Priorities, risks, benefits: assessment and perspectives Finally, the poster presents the criteria used for the selection of the infrastructures in 2022 and 2023 and draws a quick assessment of the risks identified and the benefits derived by the institution and the library; it states the perspectives and priorities and presents how this is considered as a real investment for the future.

description: A photochromic Förster resonance energy transfer (FRET) system was employed to disentangle the fluorescence quenching mechanisms in quantum dot/photochromic dye hybrids. In the off-state of the dye the main quenching mechanism is FRET whereas the moderate quenching in the on-state is due to non-FRET pathways opened up upon assembly.

Impact of LO Leakage in the New IF Frequency Range of the ALMA Wideband Sensitivity Upgrade

description: We reviewed the LO scheme in the current and the on-going upgraded receiver bands in ALMA system. Except Band-1, the fundamental frequency of the existing local oscillators in the ALMA receivers ranges from 12.4 to 25.8 GHz followed by various type of frequency multiplier. The frequency of these signals will overlap the new IF frequency range in the ALMA WSU (4-16, 4-20 GHz etc.). Therefore, spurious signal may enter in the new IF range due to the leakage. To investigate the phenomena, leakage power level at the IF output and the power ratio of the harmonics after frequency multiplication are measured in a W-band system. As expected, the "leakage" power level is proportional to the relative power ratio of the 5th/7th harmonic to 6th signal. It is thus recommended to choose the LO starting frequency as high as possible (> highest IF frequency + baseband bandwidth).

description: In this review article, we discuss photoluminescence phenomena mediated by polarons in lithium niobate (LNO). At first we present the fundamentals on polaron states in LNO and their energy levels, i.e., on free and bound electron polarons, on hole polarons as well as on bipolarons. We discuss the absorption measurements on reduced as well as on doped LNO that made the characterization of the formed polaron states possible by their absorption bands. Next, we proceed by reporting on the two polaron-mediated photoluminescence bands that have been observed in LNO: (1) A near-infrared luminescence band in the range of 1.5 eV shows a mono-exponential decay and a strong dependence on iron doping. This luminescence is emitted by bound polarons returning from an excited state to the ground state. (2) A luminescence band at visible wavelengths with a maximum at 2.6 eV shows a stretched-exponential decay and is strongly enhanced by optical damage resistant doping around the doping threshold. This luminescence stems from the recombination of free electron and hole polarons. The next major topic of this review are domain contrasts of the visible photoluminescence that have been observed after electrical poling of the substrate, as singly inverted domains show a slightly reduced and faster decaying luminescence. Subsequent annealing results in an exponential decrease of that domain contrast. We show that this contrast decay is strongly related to the mobility of lithium ions, thus confirming the role of polar defect complexes, including lithium vacancies, for these domain contrasts. Finally we discuss the extension of our investigations to lithium tantalate (LTO) samples. While the results on the domain contrast and its decay are similar to LNO, there are remarkable differences in their luminescence spectra.
