description: (min,+) convolution is the key operation in (min,+) algebra, a theory often used to compute performance bounds in real-time systems. As already observed in many works, its algorithm can be computationally expensive, due to the fact that: i) its complexity is superquadratic with respect to the size of the operands; ii) operands must be extended before starting its computation, and iii) said extension is tied to the least common multiple of the operand periods. 
In this paper, we leverage the isomorphism between (min,+) and (max,+) algebras to devise a new algorithm for (min,+) convolution, in which the need for operand extension is minimized. This algorithm is considerably faster than the ones known so far, and it allows us to abate the computation times of (min,+) convolution by orders of magnitude.

description: We present a historical review of Einstein's 1917 paper 'Cosmological Considerations in the General Theory of Relativity' to mark the centenary of a key work that set the foundations of modern cosmology. We find that the paper followed as a natural next step after Einstein's development of the general theory of relativity and that the work offers many insights into his thoughts on relativity, astronomy and cosmology. Our review includes a description of the observational and theoretical background to the paper; a paragraph-by-paragraph guided tour of the work; a discussion of Einstein's views of issues such as the relativity of inertia, the curvature of space and the cosmological constant. Particular attention is paid to little-known aspects of the paper such as Einstein's failure to test his model against observation, his failure to consider the stability of the model and a mathematical oversight concerning his interpretation of the role of the cosmological constant. We recall the response of theorists and astronomers to Einstein's cosmology in the context of the alternate models of the universe proposed by Willem de Sitter, Alexander Friedman and Georges Lemaitre. Finally, we describe the relevance of the Einstein World in today's 'emergent' cosmologies.

MATHEMATICAL MODELS IN SCIENCE: UNITING DIFFERENCES AND UNCOVERING COMMON GROUND
Creators: name: Lucas, García
Publisher: name: CARSON JOURNAL
Year: 2024
Subjects: Mathematics, interdisciplinary communication, mathematical models, quantum mechanics, conceptual variables

description: Various scientific disciplines, including biometrics, chemometrics, psychometrics, and econometrics, share a deep connection with statistics but often employ specialized applications. Effective communication across these interdisciplinary boundaries necessitates a common language, and mathematics serves as a universal bridge among the natural sciences. This article centers on the language of mathematics and its role in scientific modeling. The thesis posited here is that mathematical models should be formulated in a manner comprehensible, with some effort, to serious researchers across all disciplines, despite potential cultural barriers. The notion of "understanding" is multifaceted, exemplified by the enigmatic realm of quantum mechanics. While quantum theory is traditionally presented in an abstract language that facilitates calculations, its interpretation remains contentious, posing challenges for researchers outside the physics domain. Notably, quantum mechanics was initially expressed in distinct languages—Schrödinger's wave mechanics and Heisenberg's matrix mechanics—before being mathematically unified. This unification yielded a mathematically elegant yet conceptually intricate theory, accompanied by over 16 partially conflicting interpretations. In the works of Helland (2021) and Helland (2022a), a novel foundation is proposed, potentially more accessible to researchers beyond the quantum community. It introduces conceptual variables denoted as θ, emerging from inquiries like "What will θ be if measured?" Particularly in the discrete case, often central in textbooks and research, precise responses in the form of "θ = u" can be obtained

description: We consider the response of the density of a fermion ensemble to an applied weak static magnetic field. It is known that for non-interacting Fermi gas, this response is fully characterized by the Fermi volume and the Berry curvature on the Fermi surface. Here we show the same result holds for interacting fermions, including Fermi liquid and non-Fermi liquid, to all orders in perturbation theory. Our result relies only on the assumption of a well-defined Fermi surface and the general analytic properties of quantum field theory, and is completely model independent.

Obliquity of Mercury: influence of the precession of the pericenter and of tides

description: Mercury is expected to deviate from the classical Cassini state since this state is defined for a uniformly precessing rigid planet. We develop an extended Cassini state model that includes the variations (or nutations) in obliquity and deviation induced by the slow precession of the pericenter. The model also describes the constant shift over time in mean obliquity and deviation associated with the short-periodic tidal deformations of Mercury, characterized by the tidal love number k2 and by the ratio k2/Q of the tidal Love number over the tidal quality factor, respectively. This model is then used to interpret Mercury's orientation, including the deviation from the classical Cassini state, in terms of parameters of Mercury's interior. We determine and solve analytically the angular momentum equation, highlighting the respective roles of the pericenter precession and tidal deformations on the spin precession behavior. We also show explicitly that Peale's equation is sometimes wrongly cited in the literature, resulting in wrong estimates of the polar moment of inertia, and review the importance of many effects that change the determination of the polar moment of inertia from obliquity measurements. From the observed orientation of Stark et al. (2015b), we estimate that C/MR^2=0.3434+/-0.0102, which is ~0.9% smaller than the estimate by Stark et al. (2015b) themselves. That difference is due to our refinements of the Cassini state model (0.1%) and to their wrong use of Peale's equation (0.8%). The difference is smaller than the actual precision (3-4%) on the polar moment of inertia but may be of the order of precision that can be reached with BepiColombo mission (<=0.3%).

description: Several areas of wireless networking, such as wireless sensor networks or the Internet of Things, require application data to be distributed to multiple receivers in an area beyond the transmission range of a single node. This can be achieved by using the wireless medium’s broadcast property when retransmitting data. Due to the energy constraints of typical wireless devices, a broadcasting scheme that consumes as little energy as possible is highly desirable. In this article, we present a novel multi-hop data dissemination protocol called BTP. It uses a game-theoretical model to construct a spanning tree in a decentralized manner to minimize the total energy consumption of a network by minimizing the transmission power of each node. Although BTP is based on a game-theoretical model, it neither requires information exchange between distant nodes nor time synchronization during its operation, and it inhibits graph cycles effectively. The protocol is evaluated in Matlab and NS-3 simulations and through real-world implementation on a testbed of 75 Raspberry Pis. The evaluation conducted shows that our proposed protocol can achieve a total energy reduction of up to 90% compared to a simple broadcast protocol in real-world experiments.

We discuss the combination procedure, and the impact of improvements in the theoretical description of W-boson production and decay.
Emergence and scaling of spin turbulence in quenched antiferromagnetic spinor Bose-Einstein condensates

description: We investigate the phase transition dynamics of a quasi-2D antiferromagnetic spin-1 Bose-Einstein condensate from the easy-axis polar phase to the easy-plane polar phase, which is initiated by suddenly changing the sign of the quadratic Zeeman energy $q$. We observe the emergence and decay of spin turbulence and the formation of half-quantum vortices (HQVs) in the quenched condensate. The characteristic time and length scales of the turbulence generation dynamics are proportional to $|q|^{-1/2}$ as inherited from the dynamic instability of the initial state. In the evolution of the spin turbulence, spin wave excitations develop from large to small length scales, suggesting a direct energy cascade, and the spin population for the axial polar domains exhibit a nonexponential decay. The final equilibrated condensate contains HQVs, and the number is found to increase and saturate with increasing $|q|$. Our results demonstrate the time-space scaling properties of the phase transition dynamics near the critical point and the peculiarities of the spin turbulence state of the antiferromagnetic spinor condensate.

Year: 2023

description: In this paper, I present my research study Erzählbrücken (Narrative Bridges) and selected findings on the potential of storytelling and its multimodality for participation, meaning making and language acquisition in multilingual contexts. Next to participation and multimodality (cf. Stein 2008), crucial theoretical concepts are holistic, (syn)aesthetic and mimetic learning (cf. Spinner 2008; Wulf 2008). Erzählbrücken accompanied a storytelling project for newly immigrated primary school children in Berlin for six months. This article focusses on two video sequences. The interpretative, multimodal ‘interaction analysis’ (Krummheuer/Naujok 1999; Schmitt 2015) shows how two children participate in storytelling events even though they only understand a few words.

description: The Roentgen term is an often neglected contribution to the interaction between an atom and an electromagnetic field in the electric dipole approximation. In this work we discuss how this interaction term leads to a difference between the kinetic and canonical momentum of an atom which, in turn, leads to surprising radiation forces acting on the atom. We use a number of examples to explore the main features of this interaction, namely forces acting against the expected dipole force or accelerations perpendicular to the beam propagation axis.

description: While the particle physics community is eagerly waiting for a positive sign for the construction of the next energy frontier collider, developments continue to advance the detector capabilities. New methods and algorithms are being implemented in order to exploit the precious collisions at a Future Higgs Factory as well as possible, informing at the same time, which detector aspects are of particular importance or in fact currently limiting. In this work, three new event analysis methods are briefly introduced and put into context of hardware development for a detector at a Future Higgs Factory. While they use data from a large Geant4-based detailed MC production of the International Large Detector at the proposed International Linear Collider at an e$^+$e$^-$ center-of-mass energy of 250 GeV, the conclusions are applicable to any Future Higgs Factory.

description: The CALICE collaboration is developing highly granular electromagnetic and hadronic calorimeters for detectors at future energy frontier electron-positron colliders. After successful tests of a physics prototype, a technological prototype of the Analog Hadron Calorimeter has been built, based on a design and construction techniques scalable to a collider detector. The prototype consists of a steel absorber structure and active layers of small scintillator tiles that are individually read out by directly coupled SiPMs. Each layer has an active area of $72 \times 72\,{\rm cm}^{2}$ and a tile size of $3 \times 3\,{\rm cm}^{2}$. With $38$ active layers, the prototype has nearly $22,000$ readout channels, and its total thickness amounts to $4.4$ nuclear interaction lengths. The dedicated readout electronics provide time stamping of each hit with an expected resolution of about $1\,{\rm ns}$. The prototype was constructed in 2017 and commissioned in beam tests at DESY. It recorded muons, hadron showers and electron showers at different energies in test beams at CERN in 2018. In this paper, the design of the prototype, its construction and commissioning are described. The methods used to calibrate the detector are detailed, and the performance achieved in terms of uniformity and stability is presented.

description: Introduction: Inflammatory arthritis (IA) significantly impacts people's ability to continue in work roles, despite advances in medical management. Employment is acknowledged as important for health and wellbeing. Facilitating work participation and employment reduces social welfare dependence for income, minimising societal cost. Internationally, pathways and processes are developing to maintain people with acquired conditions in the workplace. Occupational Therapy supports this process, with its biopsychosocial approach, giving a framework to consider the complex dynamic of a person's vocational rehabilitation (VR) needs. A scoping review framework was chosen to explore the diverse VR process and emerging focus on Occupational Therapy's role in providing VR for the IA population. Methods: The methodological framework for scoping reviews will be used to guide the process and structure of the scoping review. A search strategy will be implemented in all the major peer reviewed databases along with grey literature repositories for English language studies. Study selection will use the PRISMA‐ScR flow chart against an agreed eligibility criteria by two independent reviewers. Data extraction from the final selection will be mapped out using tables and a supporting descriptive review reflecting on the original scoping review aim and objectives completed. Dissemination: Findings will be disseminated at all levels and in various formats to bring them to the attention of clinicians, researchers and policy makers as VR pathways are established and prioritised for the early IA population

description: We describe a Horava-Lifshitz-like reformulated four-fermion Gross-Neveu model describing the dynamics of two-component spinors in (2+1)-dimensional space-time. Within our study, we introduce the Lagrange multiplier, study the gap equation (including the finite temperature case) which turns out to display essentially distinct behaviors for even and odd values of the critical exponent z, and show that the dynamical parity breaking occurs only for the odd z. We demonstrate that for any odd z, there exists a critical temperature at which the dynamical parity breaking disappears. Besides of this, we obtain the effective propagator and show that the resulting effective theory is renormalizable within the framework of the 1/N expansion for all values of z. As one more application of the dynamical parity breaking, we consider coupling of the vector field to the fermions in the case of a simplified spinor-vector coupling and discuss the generation the Chern-Simons term.

description: We present a systematic and robust approach to nonlinear gravitational perturbations of vacuum spacetimes. This approach provides a basis for a theory of nonlinear gravitational waves. In particular, we show that the system of perturbative Einstein equations reduces at each perturbation order to two (for each gravitational mode in 3 + 1 dimensions on which our study is focused) scalar wave equations, and then we show how the metric perturbations can be explicitly obtained, once the solutions to these scalar wave equations are known. These results show that the concept of polarization of a gravitational wave does make sense also beyond the linear approximation.

Nearly all of China’s cotton is produced in the country’s Xinjiang Region, while textile manufacturers, the main consumers of cotton, are concentrated in coastal and central regions where cotton production has fallen dramatically. These geographic changes are a factor influencing global trade in cotton and textiles. While China’s imports of cotton are projected to gradually increase over the next decade, China’s dominant position in the cotton market appears to be weakening, with U.S. cotton exports shifting to other Asian countries.

description: The mean-field treatment of the Bose-Hubbard model predicts properties of lattice-trapped gases to be insensitive to the specific lattice geometry once system energies are scaled by the lattice coordination number $z$. We test this scaling directly by comparing coherence properties of $^{87}$Rb gases that are driven across the superfluid to Mott insulator transition within optical lattices of either the kagome ($z=4$) or the triangular ($z=6$) geometries. The coherent fraction measured for atoms in the kagome lattice is lower than for those in a triangular lattice with the same interaction and tunneling energies. A comparison of measurements from both lattices agrees quantitatively with the scaling prediction. We also study the response of the gas to a change in lattice geometry, and observe the dynamics as a strongly interacting kagome-lattice gas is suddenly "hole-doped" by introducing the additional sites of the triangular lattice.
Gamma Ray Burst afterglow and prompt-afterglow relations: an overview

description: The mechanism responsible for the afterglow emission of Gamma Ray Bursts (GRBs) and its connection to the prompt $γ$-ray emission is still a debated issue. Relations between intrinsic properties of the prompt or afterglow emission can help to discriminate between plausible theoretical models of GRB production. Here we present an overview of the afterglow and prompt-afterglow two parameter relations, their physical interpretations, their use as redshift estimators and as possible cosmological tools. A similar task has already been correctly achieved for Supernovae (SNe) Ia by using the peak magnitude-stretch relation, known in the literature as the Phillips relation \citep{phillips93}. The challenge today is to make GRBs, which are amongst the farthest objects ever observed, standardizable candles as the SNe Ia through well established and robust relations. Thus, the study of relations amongst the observable and physical properties of GRBs is highly relevant together with selection biases in their physical quantities. Therefore, we describe the state of the art of the existing GRB relations, their possible and debated interpretations in view of the current theoretical models and how relations are corrected for selection biases. We conclude that only after an appropriate evaluation and correction for selection effects can GRB relations be used to discriminate among the theoretical models responsible for the prompt and afterglow emission and to estimate cosmological parameters.

Publisher: name: MDPI
Year: 2023

description: In many modern technologies, surface-active compounds, such as surfactants, polymers, proteins, particles and their mixtures, are essential components. They change the dynamic and equilibrium properties of the inherent interfaces, which is mostly visible in foams and emulsions. The interfacial dilational visco-elasticity is probably the most informative quantity due to its direct interrelation to the equation of state of the corresponding interfacial layers as well as the mechanisms governing the interfacial molecular dynamics. The scientific field of interfacial visco-elasticity, although quite young, has been inspired by the pioneering work of Marangoni, Levich, Lucassen, Lucassen-Reynders, Hansen, van den Tempel and Krotov, and during the last decades, also significantly by Boris Noskov. His contributions to the theoretical foundation and experimental analysis of polymer and mixed surfactant–polymer interfacial layers in particular are essential.
Engineering production of specialty fragrant C15 sesquiterpenoids from the green algal Chlamydomonas reinhardtii

description: Terpenoids, a family of natural compounds with various uses, are produced by many organisms, including plants, bacteria, and mammals. However, these specialty chemicals are currently being sourced in an unsustainable manner from slow-growing plants, such as the fragrant products of the Aquilaria tree, known in the Middle East as oud and bakhour. Heterologous production of terpenoids in engineered microorganisms provides a desirable alternative source for these chemicals, which can be produced in controlled cultures rather than through native plant harvesting. Recent research has utilized the photosynthetic model green microalgae, Chlamydomonas reinhardtii, as an alternative cell chassis to produce heterologous terpenoids. This organism is interesting because it utilizes CO2 as a carbon source and light as an energy source through photosynthesis. The research presented here aimed to analyze the production of various heterologous sesquiterpenoids using C. reinhardtii as a cell chassis by modifying its native pathway to direct carbon flow toward these products to increase their production rates. A terpenoid pathway modification strategy was used in which the host squalene synthase (SQS) was knocked down to decrease the native metabolic pull on farnesyl pyrophosphate (FPP), and a beta-carotene ketolase (BKT) was induced to perturb carotenoid biosynthesis. The modifications resulted in a synergistic effect on FPP availability, increasing patchoulol production 12-fold (191 ± 25 μg/L to 2330 ± 230 μg/L). Using this strain, the production of fragrant terpenoid chemicals, including aristolochene (n=4), guaiene (n=6), santalene (n=3), valencene (n=1), valerianol (n=1), zizaene (n=2), cadinol (n=1), and bisabolol (n=1) were evaluated. Optimized synthetic transgene designs enabled their expression in the alga. The findings show that the alga can be genetically manipulated to make non-native terpenoids by improving its pool of FPP and may be an alternative source of fragrant specialty chemicals, which could prevent the unsustainable harvesting of the Aquilaria tree for cosmetic applications.

description: We present observations of two new hydrogen-poor superluminous supernovae (SLSN-I), iPTF15esb and iPTF16bad, showing late-time H-alpha emission with line luminosities of (1-3)e+41 erg/s and velocity widths of (4000-6000) km/s. Including the previously published iPTF13ehe, this makes up a total of three such events to date. iPTF13ehe is one of the most luminous and the slowest evolving SLSNe-I, whereas the other two are less luminous and fast decliners. We interpret this as a result of the ejecta running into a neutral H-shell located at a radius of ~ 1.0e+16cm. This implies that violent mass loss must have occurred several decades before the supernova explosion. Such a short time interval suggests that eruptive mass loss could be common shortly prior to the death of a massive star as a SLSN. And more importantly, helium is unlikely to be completely stripped off the progenitor stars and could be present in the ejecta. It is a mystery why helium features are not detected, even though non-thermal energy sources, capable of ionizing He atoms, may exist as suggested by the O II absorption series in the early time spectra. At late times (+240d), our spectra appear to have intrinsically lower [O I]6300A luminosities than that of SN2015bn and SN2007bi, possibly an indication of smaller oxygen masses (<10-30Msun). The blue-shifted H-alpha emission relative to the hosts for all three events may be in tension with the binary star model proposed for iPTF13ehe. Finally, iPTF15esb has a peculiar light curve with three peaks separated from one another by ~ 22 days. The LC undulation is higher in bluer bands. One possible explanation is eject-CSM interaction.

Generation of uniform microparticles by microfluidic emulsification and solvent evaporation
Creators: name: Zhang, Zilin

Subjects: Chemical engineering not elsewhere classified

description: Uniform microdroplets and designed microparticles generated by a microfluidic device with solvent evaporation are proved to have a significant impact on our everyday life such as recently in cosmetics, medicine, production of clean energy, reduction in energy consumption, the ultra-small magnets and sensors, and so on. Moreover, the properties of materials generated by monodispersed microdroplets from microfluidic devices are incredibly dependent on the synthesis method, especially on the processing route. However, all conventional microfluidic devices such like T-junction single nozzle device and the glass capillary devices can only work in a researching scale. Then, a question raised, which is, how to increase productivity on the micro level by microfluidic devices to satisfy manufacture but without sacrificing their inherent advantages especially the low cost and the monodispersity. To solve this problem, a lot of compact design based on different microfluidic mechanism have been launched. Microchannel Emulsification and SPG (Shirasu Porous Glass) membrane are two of them and provide competitive characteristics on this purpose.
National Association of Women Artists (1889-1973) 84th Annual Exhibition, May 10th thru May 27th, 1973
Creators: name: No Name Supplied

Year: 1973

description: The National Association of Women Artists (NAWA) was established in 1889 and is the oldest professional women's fine arts organization in the United States. NAWA's mission is to promote awareness of, and interest in, visual art created by women in the United States. As part of this effort NAWA holds an annual exhibition of works by members of the association and publishes an exhibition catalog to accompany or commemorate the annual exhibitions. These catalogs not only function as an exhibition catalog, but also as a document that summarizes the structure, membership, and activities of the association.Information that can be found in these catalogs includes lists of officers, members of the executive board and committees, prize winners, lists of exhibitor and members, and images of some of the artwork exhibited. Catalogs from the 2000s also include information on NAWA events and activities beyond the annual exhibition.Please note that the numbering of the annual catalogs was adjusted in 1960 and again in 1971. For example, NAWA designated the annual exhibition in 1960 as the 70th Anniversary Exhibition after 1959 was the 67th Annual Exhibition. These adjustments appear to have been made to reflect the date of the founding of the association, so that, by 1989, the annual exhibition commemorated the 100-year anniversary of the founding of NAWA in 1889.

description: Current observations of the atmospheres of close-in exoplanets are predominantly obtained with two techniques: low-resolution spectroscopy with space telescopes and high-resolution spectroscopy from the ground. Although the observables delivered by the two methods are in principle highly complementary, no attempt has ever been made to combine them, perhaps due to the different modeling approaches that are typically used in their interpretation. Here we present the first combined analysis of previously-published dayside spectra of the exoplanet HD 209458b obtained at low resolution with HST/WFC3 and Spitzer/IRAC, and at high resolution with VLT/CRIRES. By utilizing a novel retrieval algorithm capable of computing the joint probability distribution of low- and high-resolution spectra, we obtain tight constraints on the chemical composition of the planet's atmosphere. In contrast to the WFC3 data, we do not confidently detect H2O at high spectral resolution. The retrieved water abundance from the combined analysis deviates by 1.9 sigma from the expectations for a solar-composition atmosphere in chemical equilibrium. Measured relative molecular abundances of CO and H2O strongly favor an oxygen-rich atmosphere (C/O<1 at 3.5 sigma) for the planet when compared to equilibrium calculations including O rainout. From the abundances of the seven molecular species included in this study we constrain the planet metallicity to 0.1-1.0x the stellar value (1 sigma). This study opens the way to coordinated exoplanet surveys between the flagship ground- and space-based facilities, which ultimately will be crucial for characterizing potentially-habitable planets.
