description: Solving an ill-posed linear inverse problem requires knowledge about the underlying signal model. In many applications, this model is a priori unknown and has to be learned from data. However, it is impossible to learn the model using observations obtained via a single incomplete measurement operator, as there is no information about the signal model in the nullspace of the operator, resulting in a chicken-and-egg problem: to learn the model we need reconstructed signals, but to reconstruct the signals we need to know the model. Two ways to overcome this limitation are using multiple measurement operators or assuming that the signal model is invariant to a certain group action. In this paper, we present necessary and sufficient sensing conditions for learning the signal model from measurement data alone which only depend on the dimension of the model and the number of operators or properties of the group action that the model is invariant to. As our results are agnostic of the learning algorithm, they shed light into the fundamental limitations of learning from incomplete data and have implications in a wide range set of practical algorithms, such as dictionary learning, matrix completion and deep neural networks.

Year: 2025

description: The HyperLab project, funded in 2023, initially aimed at developing a mobile/web application for data analysis related to the SLab laboratory data at INAF-IAPS in Rome. The initial phase of the project focused on creating a user-friendly interface for analyzing and visualizing data from the SLab laboratory, significantly improving the efficiency of data analysis tasks. The project aims to fully leverage the powerful AI models developed by leading technology companies to significantly accelerate the creation of a functional product from scratch. The team's approach focuses on integrating pre-built models, adapting and customizing them to meet specific project requirements. This method enables small teams to effectively compete in the AI space, tapping into the collective expertise of advanced tech organizations. The model training process involved several key phases, including generating training data, creating tokens, and defining metrics to evaluate the quality of the training. The selected model, Google's T5-small, was chosen for its low resource requirements, making it ideal for an initial study phase. The project utilized containerization techniques to ensure portability, isolation, and efficiency. In summary, the HyperLab project represents an innovative and pragmatic approach to AI model training, leveraging advanced technologies to accelerate development and improve the quality of results.

description: Visual object recognition is not a trivial task, especially when the objects are degraded or surrounded by clutter or presented briefly. External cues (such as verbal cues or visual context) can boost recognition performance in such conditions. In this work, we build an artificial neural network to model the interaction between the object processing stream (OPS) and the cue. We study the effects of varying neural and representational capacities of the OPS on the performance boost provided by cue-driven feature-based feedback in the OPS. We observe that the feedback provides performance boosts only if the category-specific features about the objects cannot be fully represented in the OPS. This representational limit is more dependent on task demands than neural capacity. We also observe that the feedback scheme trained to maximise recognition performance boost is not the same as tuning-based feedback, and actually performs better than tuning-based feedback.

description: We introduce the moduli space $R \bar{M}_{2k,l}$ of pointed real curves of genus zero and give its natural stratification. The strata of $R \bar{M}_{2k,l}$ correspond to real curves of genus zero with different degeneration types and are encoded by their dual trees with certain decorations. By using this stratification, we calculate the first Stiefel-Whitney class of $R \bar{M}_{2k,l}$ and construct the orientation double cover $R \widetilde{M}_{2k,l}$$ of $R \bar{M}_{2k,l}$.

description: A novel phase transition behaviour is observed in the Kolkata Paise Restaurant (KPR) problem where large number ($N$) of agents or customers collectively (and iteratively) learn to choose among the $N$ restaurants where she would expect to be alone that evening and would get the only dish available there (or may get randomly picked up if more than one agent arrive there that evening). The players are expected to evolve their strategy such that the publicly available information about past crowd in different restaurants can be utilized and each of them is able to make the best minority choice. For equally ranked restaurants we follow two crowd-avoiding strategies: Strategy I, where each of the $n_i(t)$ number of agents arriving at the $i$-th restaurant on the $t$-th evening goes back to the same restaurant on the next evening with probability $[n_i(t)]^{-α}$, while in Strategy II, with probability $p$, when $n_i(t) > 1$. We study the steady state ($t$-independent) utilization fraction $f:(1-f)$ giving the steady state (wastage) fraction of restaurants going without any customer in any particular evening. With both the strategies we find, near $α_c=0_+$ (in strategy I) or $p=1_-$ (in strategy II), the steady state wastage fraction $(1-f)\propto(α- α_c)^β$ or $(p_c - p)^β$ with $β\simeq 0.8, 0.87, 1.0$ and the convergence time $τ$ (for $f(t)$ becoming independent of $t$) varies as $τ\propto{(α-α_c)}^{-γ}$ or ${(p_c-p)}^{-γ}$, with $γ\simeq 1.18, 1.11, 1.05$ in infinite-dimension (rest of the $N-1$ neighboring restaurants), three-dimension ($6$ neighbors) and two-dimension ($4$ neighbors) respectively.

description: This article reviews key measures of public opinion on sea-level rise (SLR): beliefs, attitudes, issue prioritization, and policy support. To do so, we first assess the influence of SLR beliefs and attitudes on issue prioritization and policy support using state-level data. Then, we compare the state findings to other surveys conducted in a hot spot of rising coastal waters, the U.S. Mid-Atlantic, to better understand the landscape of public opinion. Our findings indicate that, as in studies of climate change public opinion, belief certainty that SLR is happening and attitudes about its consequences significantly influence issue prioritization and policy support. Compared to climate change, SLR demonstrates less salience, but is similarly a low public priority. Nevertheless, the public supports governmental policies that address the issue, preferring strategies that discourage new construction in high risk areas and employ “soft” protection through natural barriers. Among the least popular approaches are those that implement hard barriers to defend against encroaching seas. Communication programs and public consultation by governments can benefit from the use of survey data to support evidence-based decision-making.
A note on palindromicity

description: Two results on palindromicity of bi-infinite words in a finite alphabet are presented. The first is a simple, but efficient criterion to exclude palindromicity of minimal sequences and applies, in particular, to the Rudin-Shapiro sequence. The second provides a constructive method to build palindromic minimal sequences based upon regular, generic model sets with centro-symmetric window. These give rise to diagonal tight-binding models in one dimension with purely singular continuous spectrum.

 Taxonomic notes: — Cyanus ermenekensis was described as an endemic species from Turkey with the name of Centaurea ermenekensis by Şirin et al. (2020) and then its name was changed to Cyanus ermenekensis by Raab-Straube & Greuter in Raab-Straube & Raus (2021). According to Şirin et al. (2020), C. ermenekensis is distinguished from C. reuterianus by its stem, number of capitula, involucre, and median appendages. Based on the description of C. ermenekensis and its comparison with C. reuterianus given by Şirin et al. (2020), and my careful examination of the important morphological traits (Wagenitz 1975) of the type specimens, I found noticeable similarities, namely flowering stem lateral at base of a rosette, usually arising from base of rosette, simple or branched in upper part, decumbent-ascending, cauline leaves lanceolate to oblanceolate, 1.8–2.9 × 0.2–0.9 cm, capitula solitary at end of stem and branches, involucres ovoid and 12–18 mm long, median appendages ovate-oblong, peripheral florets slightly radiant, central florets pink- to violet-purple, 12–16 mm long, achenes ovoid-oblong, 3.5–4.5 × 1.5–2 mm, and pappus scabrous. The only difference is that C. ermenekensis has narrower involucres and slightly smaller appendages, while C. reuterianus has wider involucres and slightly larger appendages, but following a thorough investigation of many specimens, I concluded the variation in the involucres and appendages to be continuous. Therefore, by comparing localities and geographical distributions (Fig. 7), and comparing with other samples and type specimens, I established that C. ermenekensis did not differ from C. reuterianus and should be considered as a new synonym of it.
 Distribution: — Cyanus reuterianus is endemic to Turkey.

description: Single-propagator traces are the most elementary fermion Wick contractions which occur in numerical lattice QCD, and are usually computed by introducing random-noise estimators to profit from volume averaging. The additional contribution to the variance induced by the random noise is typically orders of magnitude larger than the one due to the gauge field. We propose a new family of stochastic estimators of single-propagator traces built upon a frequency splitting combined with a hopping expansion of the quark propagator, and test their efficiency in two-flavour QCD with pions as light as 190 MeV. Depending on the fermion bilinear considered, the cost of computing these diagrams is reduced by one to two orders of magnitude or more with respect to standard random-noise estimators. As two concrete examples of physics applications, we compute the disconnected contributions to correlation functions of two vector currents in the isosinglet omega channel and to the hadronic vacuum polarization relevant for the muon anomalous magnetic moment. In both cases, estimators with variances dominated by the gauge noise are computed with a modest numerical effort. Theory suggests large gains for disconnected three and higher point correlation functions as well. The frequency-splitting estimators and their split-even components are directly applicable to the newly proposed multi-level integration in the presence of fermions.

description: The hexatic phase is an intermediate stage in the melting process of a 2D crystal due to topological defects. Recently, this exotic phase was experimentally identified in the vortex lattice of 2D weakly disordered superconducting MoGe by scanning tunneling microscopic measurements. Here we study this vortex state by the Nernst effect, which is an effective and sensitive tool to detect vortex motion, especially in the superconducting fluctuation regime. We find a surprising Nernst sign reversal at the melting transition of the hexatic phase. We propose that they are a consequence of vortex dislocations in the hexatic state which diffuse preferably from the cold to hot.

description: Chemical characteristics of novel seed oils, yet not investigated, from three endemic Arecaceae (palm) species from Reunion Island are described. Fatty acid profiles are performed using two-dimensional gas chromatography-mass spectrometry. Carotenoid contents are determined by high performance liquid chromatography-mass spectrometry. The results of the investigations emphasize the particular composition of the unconventional red seed oil from Hyophorbe indica. Characteristic features of this oil reveal a high degree of unsaturation (50% of polyunsaturated fatty acids, with a high content (17%) of omega-3), which is possibly a unique fatty acid composition in the Arecaceae family. The two other palm oils from Dictyosperma album and Latania lontaroides contain high level of saturated fatty acids very similar to that of the edible palm oil. H. indica oil is also very rich in valuable carotenoids; in particular, lutein, β-carotene and lycopene are detected in a high content (respectively 45, 23 and 35 mg.kg−1 in oil).

description: High-dimensional datasets often contain multiple meaningful clusterings in different subspaces. For example, objects can be clustered either by color, weight, or size, revealing different interpretations of the given dataset. A variety of approaches are able to identify such non-redundant clusterings. However, most of these methods require the user to specify the expected number of subspaces and clusters for each subspace. Stating these values is a non-trivial problem and usually requires detailed knowledge of the input dataset. In this paper, we propose a framework that utilizes the Minimum Description Length Principle (MDL) to detect the number of subspaces and clusters per subspace automatically. We describe an efficient procedure that greedily searches the parameter space by splitting and merging subspaces and clusters within subspaces. Additionally, an encoding strategy is introduced that allows us to detect outliers in each subspace. Extensive experiments show that our approach is highly competitive to state-of-the-art methods.

description: Many details in reading curricula (e.g., the order of materials) have analogs in laboratory studies of learning (e.g., blocking/interleaving). Principles of learning from cognitive science could be used to structure these materials to optimize learning, but they are not commonly applied. Recent work bridges this gap by “field testing” such principles: Rather than testing whole curricula, these studies teach students a small set of sound-spelling-regularities over a week via an Internet-delivered program. Training instantiates principles from cognitive science to test their application to vowel acquisition, a critical part of reading. The current study follows up on two prior studies, which found differing effects of consonant variability for learning vowels. In addition to investigating this discrepancy, this study examined a new principle: blocking/interleaving. Although interleaved training is typically beneficial, this is difficult to apply in reading where there are many regularities. We compared a fully interleaved regime (six vowels) to two blocked regimes teaching two vowels on each block. Blocked conditions differed on whether vowels overlapped (EA with OA) or not (EA with OU). Blocking was crossed with consonant variability. Four hundred seventeen first graders were pretested on six vowels, and underwent three to five days of training, followed by a posttest and retention test. Blocking had little effect. However, there was a variability benefit when overlapping vowel strings were blocked together, and no effect of variability for interleaved training. Thus, benefits may only be observed if blocking highlights contrast between regularities. When applied to real-world skills, learning principles from cognitive science may interact in complex ways.

description: We present the first high-resolution, simultaneous observations of the solar chromosphere in the optical and millimeter wavelength ranges, obtained with ALMA and the IBIS instrument at the Dunn Solar Telescope. In this paper we concentrate on the comparison between the brightness temperature observed in ALMA Band 3 (3 mm; 100 GHz) and the core width of the H$α$ 656.3 nm line, previously identified as a possible diagnostic of the chromospheric temperature. We find that in the area of plage, network and fibrils covered by our FOV the two diagnostics are well correlated, with similar spatial structures observed in both. The strength of the correlation is remarkable, given that the source function of the mm-radiation obeys local thermodynamic equilibrium, while the H$α$ line has a source function that deviates significantly from the local Planck function. The observed range of ALMA brightness temperatures is sensibly smaller than the temperature range that was previously invoked to explain the observed width variations in H$α$. We employ analysis from forward modeling with the RH code to argue that the strong correlation between H$α$ width and ALMA brightness temperature is caused by their shared dependence on the population number $n_2$ of the first excited level of hydrogen. This population number drives millimeter opacity through hydrogen ionization via the Balmer continuum, and H$α$ width through a curve-of-growth-like opacity effect. Ultimately, the $n_2$ population is regulated by the enhancement or lack of downward Ly$α$ flux, which coherently shifts the formation height of both diagnostics to regions with different temperature, respectively.

description: Cells die when they are starved of thymidine, one of the four DNA nucleotides. Since the discovery of this killing phenomenon, termed thymineless death (TLD), researchers have been trying to understand why. The goal of the work presented here is to use systems level approaches to shed light on this process. Because DNA synthesis is the only cellular process that requires thymidine, it is logical that the focus has been mainly on DNA stability and damage. My work expands the focus to new frontiers: acetate metabolism, the cytoplasm and the inner membrane.
      I generated thymidine auxotrophs in two genetic backgrounds by inactivating the thymidylate synthase enzyme, thyA. These mutants need supplementation with exogenous thymidine in order to survive. I used these strains in three experimental approaches to explore the mechanisms of TLD. Fitness profiling of a transposon insertion library in a thyA- strain, long-term laboratory evolution during thymidine-limitation, and RNA sequencing of TLD-sensitive and TLD-resistant strains identified genes in previously known processes as well as genes in novel processes. These approaches allowed me to gather rich data sets that identified many contributing genes. 52 genes showed consistent effects across approaches.
      My work confirms that ROS is a key contributor to killing during thymidine starvation and reveals that putrescine biosynthesis enzymes, an acetate overflow kinase, and the proton-transporting ATP synthase are novel players in TLD. I suggest that these three novel players contribute through their shared role in modulating cytoplasmic pH and propose a model in which DNA damage, ROS accumulation, and cytoplasmic acidification converge on the killing process during thymidine starvation. My findings expand the sites of critical action during TLD from the DNA to the cell’s inner and outer membranes and the cytoplasm. Theories on active vs. passive and specific vs. general bacterial death pathways will be discussed at the end.

description: The recent experimental synthesis of the two-dimensional (2D)boron-graphdiyne (BGDY) nanosheet has motivated us to investigate its structural, electronic,and energy storage properties. BGDY is a particularly attractive candidate for this purpose due to uniformly distributed pores which can bind the light-metal atoms. Our DFTcalculations reveal that BGDY can accommodate multiple light-metal dopants (Li, Na, K, Ca)with significantly high binding energies. The stabilities of metal functionalized BGDY monolayers have been confirmed through ab initio molecular dynamics simulations. Furthermore, significant charge-transfer between the dopantsand BGDY sheet renders the metal with a significant positive charge, which is a prerequisite for adsorbing hydrogen (H2) molecules with appropriate binding energies.This results in exceptionally high H2 storage capacities of 14.29, 11.11, 9.10 and 8.99 wt% for the Li, Na, K and Ca dopants, respectively. These H2storage capacities are much higher than many 2D materials such as graphene, graphane, graphdiyne, graphyne, C2N, silicene, and phosphorene. Average H2 adsorption energies for all the studied systems fall within an ideal window of 0.17-0.40 eV/H2. We have also performed thermodynamic analysis to study the adsorption/desorption behavior of H2, which confirmsthat desorption of the H2molecules occurs at practical conditions of pressure and temperature.

description: Determining which students are at-risk of poorer outcomes -- such as dropping out, failing classes, or decreasing standardized examination scores -- has become an important area of both research and practice in K-12 education. The models produced from this type of predictive modeling research are increasingly used by high schools in Early Warning Systems to identify which students are at risk and intervene to support better outcomes. It has become common practice to re-build and validate these detectors, district-by-district, due to different data semantics and various risk factors for students in different districts. As these detectors become more widely used, however, a new challenge emerges in applying these detectors across a broad spectrum of school districts with varying availability of past student data. Some districts have insufficient high-quality past data for building an effective detector. Novel approaches that can address the complex data challenges a new district presents are critical for advancing the field. Using an ensemble-based algorithm, I develop a modeling approach that can generate a useful model for a previously unseen district. During the ensembling process, my approach, District Similarity Ensemble Extrapolation (DSEE), weights districts that are more similar to the Target district more strongly during ensembling than less similar districts. Using this approach, I can predict student-at-risk status effectively for unseen districts, across a range of grade ranges, and achieve prediction goodness but ultimately fails to perform better than the previously published Knowles (2015) and Bowers (2012) EWS models proposed for use across districts.

description: A \emph{loop} $(B,\cdot)$ is a set $B$ together with a binary operation $\cdot$ such that (i) for each $a\in B$, the left and right translation mappings $L_{a}:B\to B: x \mapsto a\cdot x$ and $R_{a}:B\to B: x \mapsto x\cdot a$ are bijections, and (ii) there exists a two-sided identity element $1\in B$. Thus loops can be thought of as "nonassociative groups". In this paper we study standard, internal and external semidirect products of loops with groups. These are generalizations of the familiar semidirect product of groups.

Exploring a behavioral role for presynaptic inhibition at spinal sensory-motor synapses

Publisher: name: Columbia University
Year: 2013
Subjects: subject: Neurosciences
subject: FOS: Clinical medicine

description: The precision of mammalian movement relies on excitatory sensory feedback supplied by proprioceptors, and its context-dependent refinement by spinal inhibitory microcircuits. One microcircuit that has been implicated in the regulation of sensory input establishes inhibitory synapses directly on the central terminals of sensory neurons. To date, however, the difficulty in gaining selective access to discrete classes of inhibitory interneurons within local microcircuits has left unresolved the contribution of presynaptic inhibition, if any, to motor behavior. Here we have used mouse genetics to gain access to the set of GABAergic interneurons that provide direct input to sensory terminals, and show that their activation evokes the defining physiological features of presynaptic inhibition. Genetic ablation of this set of interneurons in the adult severely perturbs goal-directed reaching movements, and uncovers a pronounced forelimb motor oscillation that appears to have its basis in an enhancement in the gain of sensory feedback. Together, our findings uncover an essential motor behavioral role for this specialized set of presynaptic inhibitory interneurons, and emphasize the relevance of sensory gain control in the neural programming of skilled movement.

description: Two-level atoms coupled with single-mode cavity photons are predicted to exhibit a quantum phase transition when the coupling strength exceeds a critical value, entering a phase in which atomic polarization and photonic field are finite even at zero temperature and without external driving. However, this phenomenon, the superradiant phase transition (SRPT), is forbidden by a no-go theorem due to the existence of the diamagnetic term in the Hamiltonian. Here, we present spectroscopic evidence for a magnonic SRPT in ErFeO$_3$, where the role of the photonic mode (two-level atoms) in the photonic SRPT is played by an Fe$^{3+}$ magnon mode (Er$^{3+}$ spins). The absence of the diamagnetic term in the Fe$^{3+}$-Er$^{3+}$ exchange coupling ensures that the no-go theorem does not apply. Terahertz and gigahertz magnetospectroscopy experiments revealed the signatures of the SRPT -- a kink and a softening, respectively, of two spin-magnon hybridized modes at the critical point.
