description: Child malnutrition is a significant predicament in Benin, with 32% of children under the age of five being stunted and 5% wasted. The artisanal production of affordable, tasty, and nutritious baby food by local women entrepreneurs has the potential to mitigate this issue. Nevertheless, appropriate, professional and attractive packaging is necessary to reduce spoilage and gain access to markets in both urban and peri-urban areas. The aim of our investigation was to identify items that could potentially convey affirmative quality characteristics on the packaging of infant formula for mothers. To achieve this, we conducted a photovoice study in the Parakou community, situated in northern Benin, with 15 mothers of children below the age of five. The photovoice methodology delineates the experiences and perceptions of the participants through photographs. The findings indicated that thirteen photographs of various elements, including nature (fruits, trees, gardens), people (babies), and utensils, had a positive value for the mothers. However, it still needs to be determined whether the depiction of these elements or their derivatives on the packaging of children's food would generate interest and instill confidence in mothers to accept artisanal child food products. This could become a competitive advantage for local producers of infant foods in the face of competition from imported products.

description: A new era of defragmentation of the global world space is coming. The unipolar («American-centric») construction of the modern world is becoming a thing of the past, and instead of global superiority in the system of world domination, the imperative of national power arises and develops. Friendship between Russia and the «global West» no matter how hard our homegrown liberals have tried for the past 30 years, has not developed. The liberal economic model also did not take root on Russian soil. Therefore, under the current conditions, strategic planning is the optimal methodological approach to determining the dominant goals for the development of the Arctic, as the largest geostrategic region of Russia.

description: Comparative analyses of graph structured datasets underly diverse problems. Examples of these problems include identification of conserved functional components (biochemical interactions) across species, structural similarity of large biomolecules, and recurring patterns of interactions in social networks. A large class of such analyses methods quantify the topological similarity of nodes across networks. The resulting correspondence of nodes across networks, also called node alignment, can be used to identify invariant subgraphs across the input graphs. Given $k$ graphs as input, alignment algorithms use topological information to assign a similarity score to each $k$-tuple of nodes, with elements (nodes) drawn from each of the input graphs. Nodes are considered similar if their neighbors are also similar. An alternate, equivalent view of these network alignment algorithms is to consider the Kronecker product of the input graphs, and to identify high-ranked nodes in the Kronecker product graph. Conventional methods such as PageRank and HITS (Hypertext Induced Topic Selection) can be used for this purpose. These methods typically require computation of the principal eigenvector of a suitably modified Kronecker product matrix of the input graphs. We adopt this alternate view of the problem to address the problem of multiple network alignment. Using the phase estimation algorithm, we show that the multiple network alignment problem can be efficiently solved on quantum computers. We characterize the accuracy and performance of our method, and show that it can deliver exponential speedups over conventional (non-quantum) methods.

description: In this paper, we studied Einsteinian quartic gravity minimally coupled to electrodynamics in four dimensions. First, by variation action, we obtain the field equations, and by integration, we obtain a nonlinear third-order differential equation for the metric function and as well as the electromagnetic potential. Then, in the context of the Maxwell field, we discussed the conditions under which the charged black hole exists. Then, we have demonstrated the thermodynamics and stability of the solution for the case of positive coupling of quartic theory. Finally, we showed that the charged black hole solutions of EQG (unlike GR and like ECG) have no inner horizon and do not conform to the extremal bound of GR. Also, the uniqueness of BH solutions in this theory does not work anymore.

description: Logistics of using hydroponics to support urban agriculture in a value network context is conceptualised through an empirically grounded model. This is developed employing a single case study that reveals hydroponics use in a value network, a local and transparent form of inter-organizational cooperation. Hydroponics use for urban farming in its networked context reveals this form of food supply as a local ecosystem, alternative to modernistic large scale geographically distant to consumption-type farming. The empirically grounded conceptual model reveals how this recent technology is only one of many factors that in combination provide understanding on how sustainable production of safe and quality foods may be achieved with focus on its impact on logistical operations. Hydroponics use as revealed in the case shortens logistics flows and greatly simplifies logistics operations since it is a local type of goods distribution. This model provides basis for further research on use of small-scale indoor urban farming technology from a logistics perspective highlighting features of using this technology economically to supply urban food consumption through loosely coupled food production.

description: We report on the realization of a novel degenerate mixture of ultracold fermionic lithium and chromium atoms. Based on an all-optical approach, with an overall duty-cycle of about 13 seconds, we produce large and degenerate samples of more than 2$\times 10^5$ $^6$Li atoms and $10^5$ $^{53}$Cr atoms, with both species exhibiting normalized temperatures of about $T/T_{F}$=0.25. Additionally, through the exploitation of a crossed bichromatic optical dipole trap, we can controllably vary the density and degree of degeneracy of the two components almost independently, and widely tune the lithium-to-chromium density ratio. Our $^{6}$Li-$^{53}$Cr Fermi mixture opens the way to the investigation of a variety of exotic few- and many-body regimes of quantum matter, and it appears as an optimally-suited system to realize ultracold paramagnetic polar molecules, characterized by both electric and magnetic dipole moments. Ultimately, our strategy also provides an efficient pathway to produce dipolar Fermi gases, or spin-mixtures, of ultracold $^{53}$Cr atoms.

description: Gallic acid is a well-recognized naturally occurring compound possessing antioxidant activities. The free radical scavenging ability of gallic acid for fifty reactive species, such as oxygen, nitrogen, and sulfur-containing species, has been studied using the formal hydrogen atom transfer mechanism. The theoretical studies have been conducted in the gas phase and aqueous solution at M05-2X/6-311++G** level using the density functional theory (DFT) calculations. The relative damaging potential of all the reactive species has been compared by investigating their hydrogen atom and electron affinity. Furthermore, a comparison of their relative reactivity was made by evaluating several global chemical reactivity descriptors. Additionally, the feasibility of scavenging the species by gallic acid has been studied by computing the redox potentials and equilibrium constants for the overall process in the aqueous solution.

description: Two central topics of study in combinatorics are the so-called evolution of random graphs, introduced by the seminal work of Erdős and Rényi, and the family of $H$-free graphs, that is, graphs which do not contain a subgraph isomorphic to a given (usually small) graph $H$. A widely studied problem that lies at the interface of these two areas is that of determining how the structure of a typical $H$-free graph with $n$ vertices and $m$ edges changes as $m$ grows from $0$ to $\text{ex}(n,H)$. In this paper, we resolve this problem in the case when $H$ is a clique, extending a classical result of Kolaitis, Prömel, and Rothschild. In particular, we prove that for every $r \ge 2$, there is an explicit constant $θ_r$ such that, letting $m_r = θ_r n^{2-\frac{2}{r+2}} (\log n)^{1/\left[\binom{r+1}{2}-1\right]}$, the following holds for every positive constant $\varepsilon$. If $m \ge (1+\varepsilon) m_r$, then almost all $K_{r+1}$-free $n$-vertex graphs with $m$ edges are $r$-partite, whereas if $n \ll m \le (1-\varepsilon)m_r$, then almost all of them are not $r$-partite.

description: Cold atmospheric pressure plasmas are promising medical tools that can assist in cancer treatment. While the medical pathology mechanism is substantially understood, knowledge of the contribution of reactive species formed in plasma and the mode of activation of biochemical pathways is insufficient. Herein, we present a concept involving antitumoral plasma-activated organics, which is envisaged to increase cytotoxicity levels against cancer cells. Ringer′s acetate solution was irradiated by low-temperature plasma at atmospheric pressure and possible reaction pathways of the compound generation are presented. The chemical compounds formed by plasma treatment and their effects on non-tumorigenic breast epithelial cells (MCF-10A) and breast cancer cells (MCF-7) were investigated. The cell viability results have shown that plasma-derived compounds have both, stimulatory and inhibitory effects on cell viability, depending on the concentration of the generated compounds in the irradiated liquids. Previous studies have shown that oxidative stresses involving reactive oxygen and nitrogen species (RONS) can be used to kill cancer cells. Hence, while RONS offers promising first-step killing effects, cell viability results have shown that plasma-derived compounds, such as acetic anhydride and ethyl acetate, have the potential to play important roles in plasma-based cancer therapy.
Behavior near the extinction time in self-similar fragmentations II: Finite dislocation measures

description: We study a Markovian model for the random fragmentation of an object. At each time, the state consists of a collection of blocks. Each block waits an exponential amount of time with parameter given by its size to some power $α$, independently of the other blocks. Every block then splits randomly into sub-blocks whose relative sizes are distributed according to the so-called dislocation measure. We focus here on the case where $α<0$. In this case, small blocks split intensively, and so the whole state is reduced to "dust" in a finite time, almost surely (we call this the extinction time). In this paper, we investigate how the fragmentation process behaves as it approaches its extinction time. In particular, we prove a scaling limit for the block sizes which, as a direct consequence, gives us an expression for an invariant measure for the fragmentation process. In an earlier paper [Ann. Inst. Henri Poincaré Probab. Stat. 46 (2010) 338-368], we considered the same problem for another family of fragmentation processes, the so-called stable fragmentations. The results here are similar, but we emphasize that the methods used to prove them are different. Our approach in the present paper is based on Markov renewal theory and involves a somewhat unusual "spine" decomposition for the fragmentation, which may be of independent interest.

description: In this work, we observe that in the presence of the string cloud parameter $a$ and the quintessence parameter $γ$, with the equation of state parameter $ω_q={-2}/{3}$ the radius of the shadow of the Schwarzschild black hole increases as compared with the pure Schwarzschild black hole case. The existence of both quintessential dark energy and cloud of strings magnify the shadow size and hence the strength of the gravitational field around the Schwarzschild black hole increases. Using the data collected by the Event Horizon Telescope (EHT) collaboration for the M87* and Sgr A*, we obtain upper bounds on the values of the parameters $a$ and $γ$. Further, we see the effects of the parameters $a$ and $γ$ on the rate of emission energy for the Schwarzschild black hole. We notice that the rate of emission energy is higher in the presence of clouds of string and quintessence. Moreover, we study the weak deflection angle using the Gauss-Bonnet theorem. We show the influence of the cloud of string parameter $a$ and the quintessential parameter $γ$ on the weak deflection angle. We notice that both the parameters $a$ and $γ$ increase the deflection angle $α$.

description: This work explores the structure of Poincare-Lindstedt perturbation series in Deprit operator formalism and establishes its connection to Kato resolvent expansion. A discussion of invariant definitions for averaging and integrating perturbation operators and their canonical identities reveals a regular pattern in a Deprit generator. The pattern was explained using Kato series and the relation of perturbation operators to Laurent coefficients for the resolvent of Liouville operator. This purely canonical approach systematizes the series and leads to the explicit expression for the Deprit generator in any perturbation order: \[G = - \hat{\mathsf S}_H H_i.\] Here, $\hat{\mathsf S}_H$ is the partial pseudo-inverse of the perturbed Liouville operator. Corresponding Kato series provides a reasonably effective computational algorithm. The canonical connection of perturbed and unperturbed averaging operators allows for a description of ambiguities in the generator and transformed Hamiltonian, while Gustavson integrals turn out to be insensitive to normalization style. Non-perturbative examples are used for illustration.

description: State-of-the-art audio captioning methods typically use the encoder-decoder structure with pretrained audio neural networks (PANNs) as encoders for feature extraction. However, the convolution operation used in PANNs is limited in capturing the long-time dependencies within an audio signal, thereby leading to potential performance degradation in audio captioning. This letter presents a novel method using graph attention (GraphAC) for encoder-decoder based audio captioning. In the encoder, a graph attention module is introduced after the PANNs to learn contextual association (i.e. the dependency among the audio features over different time frames) through an adjacency graph, and a top-k mask is used to mitigate the interference from noisy nodes. The learnt contextual association leads to a more effective feature representation with feature node aggregation. As a result, the decoder can predict important semantic information about the acoustic scene and events based on the contextual associations learned from the audio signal. Experimental results show that GraphAC outperforms the state-of-the-art methods with PANNs as the encoders, thanks to the incorporation of the graph attention module into the encoder for capturing the long-time dependencies within the audio signal. The source code is available at https://github.com/LittleFlyingSheep/GraphAC.

description: Tracer particles designed specifically for X-ray particle tracking and imaging velocimetry (XPTV and XPIV) are necessary to widen the range of flows that can be studied with these techniques. In this study, we demonstrate in-lab XPTV using new, custom-designed $O$(50 $μ$m) diameter tungsten-coated hollow carbon spheres and a single energy threshold photon counting detector. To explore the measurement quality enhancement enabled by the new tracer particles and photon counting detector, a well understood Poiseulle pipe flow is measured. The data show agreement with the analytical solution for the depth-averaged velocity profile. The experiment also shows that the tungsten-coated particles achieve higher contrast and are better localized than previously available silver-coated particles, making faster and more precise measurements attainable. The particles are manufactured with a readily scalable chemical vapor deposition process. We further show that laboratory XPTV is practical with currently available energy-resolving photon counting detectors (PCDs), despite their presently lower spatiotemporal resolution compared to scintillating detectors. This finding suggests that energy-thresholding identification of different classes of tracers is feasible, further motivating the exploration of the X-ray tracer particle design space. The latest generation of PCDs are incorporating multiple energy thresholds, and have higher count rate limits. In the near future one could potentially expand on the work presented and track multiple tracer species and scalar fields simultaneously.

description: A recent proposed method for $α$-decay energies ($Q_α$) [J.M. Dong, W. Zuo, and W. Scheid, Phys. Rev. Lett. \textbf{107}, 012501 (2011)] can reproduce experimental data of superheavy nuclei (SHN) with an $rms$-value of less than 100 keV. However, a sinusoid-like periodic deviation from experiments, which limits the accuracy in predictions, is observed when using different reference nuclei. In this paper, we have further extended this hybrid method, i.e., to predict $Q_α$ of the as-yet-unobserved SHN with the help of known nuclei. It is found that the systematic deviation in previous study is rooted in the nuclear mass model employed. By further analyzing the source of errors, different nuclear mass models are evaluated based on the same procedure.

Conditioning of Random Feature Matrices and Sparse Recovery

subject: FOS: Mathematics

description: This thesis presents theoretical results in two areas. The first is conditioning of random feature matrices and the second is behaviors and convergence of weighted sparse identification of nonlinear dynamics (SINDy) algorithm. The spectra of random feature matrices provide essential information on the conditioning of the linear system used in random feature regression problems and are thus connected to the consistency and generalization of random feature models. We provide (high probability) bounds on the concentration of singular values of random feature matrices. In particular, we show that if the complexity ratio N/m where m is the number of data samples and N is the number of random features scales like log(m) or log−1 (N), then the random feature matrix is well-conditioned. When the dimension d is moderately large (e.g., d ≥ log(m) or d ≥ log(N)), the results hold in the setting when both data and features are random or one is random and the other is well-separated. For random Fourier feature matrix, we show that it satisfies s-restricted isometry property, and its s-restricted isometry constant is bounded if m scales like s log4 (N). We also derive upper bounds for the risk associated with regression problems using a random feature matrix in both the underparameterized setting and the overparameterized setting. This upper bound exhibits the double descent phenomenon and it is an effect of the double descent behavior of the condition number. Our bounds match the optimal scaling in the literature and the constants in our results are explicit and independent of the dimension of the data. The SINDy algorithm proposed in [18] is a sparsity-promoting algorithm. We generalize it to a weighted version which allows for the approximation of sparse vectors with small nonzero entries. We prove that the weighted SINDy algorithm has similar convergence properties and can approximate local minimizers of a non-convex objective function. Additionally, when prior information on the sparsity pattern of the target vector is available, we show that the optimization problem can be converted into an equivalent problem of smaller size, and weighted SINDy algorithm is able to recover partially sparse vectors. Numerical examples show that weighted SINDy algorithm can recovery the support more accurately than the original SINDy algorithm.

description: The order/dimension of models derived on the basis of data is commonly restricted by the number of observations, or in the context of monitored systems, sensing nodes. This is particularly true for structural systems (e.g., civil or mechanical structures), which are typically high-dimensional in nature. In the scope of physics-informed machine learning, this paper proposes a framework -- termed Neural Modal ODEs -- to integrate physics-based modeling with deep learning for modeling the dynamics of monitored and high-dimensional engineered systems. Neural Ordinary Differential Equations -- Neural ODEs are exploited as the deep learning operator. In this initiating exploration, we restrict ourselves to linear or mildly nonlinear systems. We propose an architecture that couples a dynamic version of variational autoencoders with physics-informed Neural ODEs (Pi-Neural ODEs). An encoder, as a part of the autoencoder, learns the abstract mappings from the first few items of observational data to the initial values of the latent variables, which drive the learning of embedded dynamics via physics-informed Neural ODEs, imposing a modal model structure on that latent space. The decoder of the proposed model adopts the eigenmodes derived from an eigen-analysis applied to the linearized portion of a physics-based model: a process implicitly carrying the spatial relationship between degrees-of-freedom (DOFs). The framework is validated on a numerical example, and an experimental dataset of a scaled cable-stayed bridge, where the learned hybrid model is shown to outperform a purely physics-based approach to modeling. We further show the functionality of the proposed scheme within the context of virtual sensing, i.e., the recovery of generalized response quantities in unmeasured DOFs from spatially sparse data.

description: Layered stable (multivariate) distributions and processes are defined and studied. A layered stable process combines stable trends of two different indices, one of them possibly Gaussian. More precisely, in short time, it is close to a stable process while, in long time, it approximates another stable (possibly Gaussian) process. We also investigate the absolute continuity of a layered stable process with respect to its short time limiting stable process. A series representation of layered stable processes is derived, giving insights into both the structure of the sample paths and of the short and long time behaviors. This series is further used for sample paths simulation.

Zeno's Paradoxes. A Cardinal Problem 1. On Zenonian Plurality

description: In this paper the claim that Zeno's paradoxes have been solved is contested. Although no one has ever touched Zeno without refuting him (Whitehead), it will be our aim to show that, whatever it was that was refuted, it was certainly not Zeno. The paper is organised in two parts. In the first part we will demonstrate that upon direct analysis of the Greek sources, an underlying structure common to both the Paradoxes of Plurality and the Paradoxes of Motion can be exposed. This structure bears on a correct - Zenonian - interpretation of the concept of division through and through. The key feature, generally overlooked but essential to a correct understanding of all his arguments, is that they do not presuppose time. Division takes place simultaneously. This holds true for both PP and PM. In the second part a mathematical representation will be set up that catches this common structure, hence the essence of all Zeno's arguments, however without refuting them. Its central tenet is an aequivalence proof for Zeno's procedure and Cantor's Continuum Hypothesis. Some number theoretic and geometric implications will be shortly discussed. Furthermore, it will be shown how the Received View on the motion-arguments can easely be derived by the introduction of time as a (non-Zenonian) premiss, thus causing their collapse into arguments which can be approached and refuted by Aristotle's limit-like concept of the potentially infinite, which remained - though in different disguises - at the core of the refutational strategies that have been in use up to the present. Finally, an interesting link to Newtonian mechanics via Cremona geometry can be established.

Investigation of the Impact of Vegetarianism and Veganism on the Post-Covid-19 Gastronomy and Food Industry

description: The aim of this term paper is to investigate the extent to which Covid-19 has influenced the gastronomy and food sector regarding fresh food counters and the to-go assortment in terms of vegetarian and vegan offerings. An extensive literature and internet research was conducted for this thesis. In addition, this included a study of vegan- and vegetarian-friendly food offerings in ten different randomly selected restaurants in the city of Trier, Germany. The results show that on average a good selection of vegetarian dishes (33.6%) and a small selection of vegan dishes (11.8%) can be found in the individual restaurants. The trend towards a plant-based diet has been evident for years but accelerated during the COVID-19 pandemic as society began to doubt the safety precautions of the meat industry and awareness of animal, environmental and health issues increased. This has led to many restaurants and food retailers expanding their range of vegetarian and vegan options to meet this demand. More and more vegan products can also be found in food retail, and the range of vegan alternative products in the to-go area or at fresh food counters for actual meat, sausage, cheese and fish products is expanding, as can be seen at pioneer REWE Group, for example.

Staircase solutions and stability in vertically confined salt-finger convection

description: Bifurcation analysis of confined salt-finger convection using single-mode equations obtained from a severely truncated Fourier expansion in the horizontal is performed. Strongly nonlinear staircase-like solutions having, respectively, one (S1), two (S2) and three (S3) regions of mixed salinity in the vertical direction are computed using numerical continuation, and their stability properties are determined. Near onset, the one-layer S1 solution is stable and corresponds to maximum salinity transport among the three solutions. The S2 and S3 solutions are unstable but exert an influence on the statistics observed in direct numerical simulations (DNS) in larger two-dimensional (2D) domains. Secondary bifurcations of S1 lead either to tilted-finger (TF1) or to traveling wave (TW1) solutions, both accompanied by the spontaneous generation of large-scale shear, a process favored for lower density ratios and Prandtl numbers (Pr). These states at low Pr are associated, respectively, with two-layer and three-layer staircase-like salinity profiles in the mean. States breaking reflection symmetry in the midplane are also computed. In 2D and for low Pr the DNS results favor direction-reversing tilted fingers (RTF) resembling the pulsating wave state observed in other systems. Two-layer and three-layer mean salinity profiles corresponding to RTF and TW1 are observed in 2D DNS averaged over time. The single-mode solutions close to the high wavenumber onset are in an excellent agreement with 2D DNS in small horizontal domains and compare well with 3D DNS.

Nalebuff, Barry (2022). Split The Pie. A Radical New Way to Negotiate
Creators: name: Mueller, Rolf A.E.
Publisher: name: International Journal on Food System Dynamics
Year: 2023

description: The book is part of a bundle of tools for teaching the "split the pie" framework to students of negotiation. Nalebuff considers his "split the pie" framework for negotiations as one that is consistent, fair to both sides of a negotiation, and that reflects the equal power of negotiation partners. The other tools, which are assembled on a companion website (https://www.splitthepiebook.com/), include an online course, quizzes, videos, a negotiation bot, and slides for teachers.

Early Greek Thought and Perspectives for the Interpretation of Quantum Mechanics: Preliminaries to an Ontological Approach
Creators: name: Verelst, K.
name: Coecke, B.
Publisher: name: arXiv
Year: 2006
Subjects: subject: History and Philosophy of Physics (physics.hist-ph)
subject: FOS: Physical sciences

description: It will be shown in this article that an ontological approach for some problems related to the interpretation of Quantum Mechanics could emerge from a re-evaluation of the main paradox of early Greek thought: the paradox of Being and non-Being, and the solutions presented to it by Plato and Aristotle. Plato's and Aristotle's systems are argued here to do on the ontological level essentially the same: to introduce stability in the world by introducing the notion of a separable, stable object, for which a principle of contradiction is valid: an object cannot be and not-be at the same place at the same time. After leaving Aristotelian metaphysics, early modern science had to cope with these problems: it did so by introducing ``space'' as the seat of stability, and ``time'' as the theater of motion. But the ontological structure present in this solution remained the same. Therefore the fundamental notion `separable system', related to the notions observation and measurement, themselves related to the modern concepts of space and time, appears to be intrinsically problematic, because it is inextricably connected to classical logic on the ontological level. We see therefore the problems dealt with by quantum logic not as merely formal, and the problem of `non-locality' as related to it, indicating the need to re-think the notions `system', `entity', as well as the implications of the operation `measurement', which is seen here as an application of classical logic (including its ontological consequences) on the material world.
