description: This study presents an innovative theoretical approach to dark energy and dark matter, which are key components in explaining the expansion of the universe and the dynamics of large-scale structures. While dark energy drives the accelerated expansion of the universe, dark matter plays a critical role in the formation of galaxy clusters and the underlying structure of the cosmos.

The key aspects of the study include:

1. Tensor-Based Energy Cycles:

A tensor-based mathematical model is developed to elucidate the relationship between dark energy and dark matter.

This model utilizes energy gradients and spacetime deformation effects to predict the density of dark energy.

2. Deformation Constant (de):

The deformation constant (de) is introduced as an innovative parameter to calculate the cosmological effects of energy transformations.

3. Quantum and Cosmological Connections:

Dark energy and dark matter are explored as bridges between quantum field theory and general relativity.

Gradient-based calculations suggest a direct relationship between dark energy and dark matter.

4. Observational Data:

The model is validated against observational datasets, including the Planck Legacy Archive (CMB data) and the Dark Energy Survey (DES).

The results demonstrate alignment with the universe's expansion rate and the density distribution of dark matter.

5. Particle-Independent Approach:

The study proposes a framework that relies solely on energy densities, providing an alternative to particle-based models for dark matter and dark energy. This simplifies the understanding of their physical mechanisms.

Conclusion

This research offers a novel perspective on dark energy and dark matter, introducing tensor-based energy cycles and the deformation constant as key concepts. These innovations provide a robust theoretical framework to explain the relationship between these two phenomena. The study's findings are consistent with observational data, underscoring the potential cosmological implications of the proposed model.The author acknowledges the use of OpenAI’s language model for assistance in drafting certain sections of this workl

description: We have analyzed the interplay between noise and periodic modulations in a mean field model of a neural excitable medium. To this purpose, we have considered two types of modulations; namely, variations of the resistance and oscillations of the threshold. In both cases, stochastic resonance is present, irrespective of if the system is monostable or bistable.

Breaking the Radio - Gamma-Ray Connection in Arp 220

description: Recent analyses of the gamma-ray spectrum from the ultra-luminous infrared galaxy Arp 220 have revealed a discrepancy in the cosmic ray energy injection rates derived from the gamma-rays versus the radio emission. While the observed radio emission is consistent with the star formation rate inferred from infrared observations, a significantly higher cosmic ray population is necessary to accurately model the measured gamma-ray flux. To resolve this discrepancy between the radio and gamma-ray observations, we find that we must increase the cosmic ray energy injection rate and account for an infrared optical depth greater than unity. Raising the energy injection rate naturally raises the total gamma-ray flux but also raises the radio flux unless there is also an increase in the energy loss rate for cosmic ray leptons. A optically thick medium results in an increase in energy losses via inverse Compton for cosmic ray leptons and preserves agreement with submillimeter, millimeter, and infrared wavelength observations.

description: Polymer nanocomposites are already a part of many important worldwide businesses. Among many nanocomposite precursors, titanium dioxide (TiO2) nanopowder is increasingly being investigated due to its special properties. In this work, the feasibility of synthesising a new series of materials, copoly(arylidene-ether)/titanium dioxide nanocomposites, using in-situ copolymerisation technique has been investigated. This can be performed by the interaction of both cyclohexanone and 4-tert-butylcyclohexanone monomers with 4,4′-diformyl-2,2′-dimethoxy-α,ω-diphenoxyalkanes Ia–e, respectively, using different additions of titanium dioxide-P25. The structure of the prepared nanocomposites IIa–e/TiO2 (0.2–3.0%) was confirmed by elemental analysis (energy dispersive X-ray spectroscopy) and spectral data (Fourier transform-infrared [FT-IR]). FT-IR verified the dispersion of nanofillers in the copolymer. Then, the characterisation and applications of these nanocomposites are extensively discussed depending on the investigation of how the addition of titanium dioxide nanoparticles affected on their properties using various techniques, such as X-ray diffraction, SEM, transmission electron microscopy, Water Contact Angle (WCA), thermogravimetric analysis, differential thermogravimetric, differential thermal analysis (DTA), polarising optical microscope and UV–vis absorption spectroscopy. The nanoparticles affected on the copolymer thermal behaviour in different ways (discrepancy results) depending on how these nanoparticles are dispersed in the copolymer matrix. UV–vis absorption spectra displayed a decrease in the optical band gap of some nanocomposites, which resulted from the addition of titanium dioxide to these copolymers, and this can improve the efficiency of them as organic emitting materials.

description: This is a review of Tim Benton's LC Foto Le Corbusier Secret Photographer (2013), an immaculately researched and well-written book which covers the development of Le Corbusier’s photographic output. Le Corbusier had an ambiguous relationship with photography throughout his career; on the one hand he relied heavily on professional photography to promote his built work and support his discourse, but on the other hand he ‘maintained that photography was a stultifying activity, good only for lazy people’. In managing this image, he never allowed himself to be photographed holding a camera, while from 1916 and 1921, and again between 1936 and 1938, he literally took hundreds of photographs.

description: UX Orionis stars (UXors) are Herbig Ae/Be or T Tauri stars exhibiting sporadic occultation of stellar light by circumstellar dust. GM\,Cephei is such a UXor in the young ($\sim4$~Myr) open cluster Trumpler\,37, showing prominent infrared excess, emission-line spectra, and flare activity. Our photometric monitoring (2008--2018) detects (1)~an $\sim$3.43~day period, likely arising from rotational modulation by surface starspots, (2)~sporadic brightening on time scales of days due to accretion, (3)~irregular minor flux drops due to circumstellar dust extinction, and (4)~major flux drops, each lasting for a couple of months with a recurrence time, though not exactly periodic, of about two years. The star experiences normal reddening by large grains, i.e., redder when dimmer, but exhibits an unusual "blueing" phenomenon in that the star turns blue near brightness minima. The maximum extinction during relatively short (lasting $\leq 50$~days) events, is proportional to the duration, a consequence of varying clump sizes. For longer events, the extinction is independent of duration, suggestive of a transverse string distribution of clumps. Polarization monitoring indicates an optical polarization varying $\sim3\%$--8$\%$, with the level anticorrelated with the slow brightness change. Temporal variation of the unpolarized and polarized light sets constraints on the size and orbital distance of the circumstellar clumps in the interplay with the young star and scattering envelope. These transiting clumps are edge-on manifestations of the ring- or spiral-like structures found recently in young stars with imaging in infrared of scattered light, or in submillimeter of thermalized dust emission.

description: We have designed the Extremely Luminous Quasar Survey (ELQS) to provide a highly complete census of unobscured UV-bright quasars during the cosmic noon, $z=2.8-5.0$. Here we report the discovery of 70 new quasars in the ELQS South Galactic Cap (ELQS-S) quasar sample, doubling the number of known extremely luminous quasars in $4,237.3\,\rm{deg}^2$ of the SDSS footprint. These observations conclude the ELQS and we present the properties of the full ELQS quasar catalog, containing 407 quasars over $11,838.5\,\rm{deg}^2$. Our novel ELQS quasar selection strategy resulted in unprecedented completeness at the bright end and allowed us to discover 109 new quasars in total. This marks an increase of $\sim36\%$ (109/298) to the known population at these redshifts and magnitudes, while we further are able to retain a selection efficiency of $\sim80\%$. On the basis of 166 quasars from the full ELQS quasar catalog, who adhere to the uniform criteria of the 2MASS point source catalog, we measure the bright-end quasar luminosity function (QLF) and extend it one magnitude brighter than previous studies. Assuming a single power law with exponential density evolution for the functional form of the QLF, we retrieve the best fit parameters from a maximum likelihood analysis. We find a steep bright-end slope of $β\approx-4.1$ and we can constrain the bright-end slope to $β\leq-3.4$ with $99\%$ confidence. The density is well modeled by the exponential redshift evolution, resulting in a moderate decrease with redshift ($γ\approx-0.4$).

The dynamical susceptibility $χ''(q,ω)$ at the incommensurate positions increases on cooling below $T_c$, accompanied by a suppression of magnetic fluctuations at the commensurate points.

description: We present results from our 47-night imaging campaign of Comet 41P/Tuttle-Giacobini-Kresak conducted from Lowell Observatory between 2017 February 16 and July 2. Coma morphology revealed gas jets, whose appearance and motion as a function of time yielded the rotation period and other properties. All narrowband CN images exhibited either one or two jets; one jet appeared as a partial face-on spiral with clockwise rotation while the second jet evolved from a side-on corkscrew, through face-on, and finally corkscrew again, with only a slow evolution throughout the apparition due to progressive viewing geometry changes. A total of 78 period determinations were made over a 7-week interval, yielding a smooth and accelerating rotation period starting at 24 hr (March 21&22) and passing 48 hr on April 28. While this is by far the fastest rate of change ever measured for a comet nucleus, the torque required is readily within what can exist given likely properties of the nucleus. If the torque remained constant, we estimate that the nucleus could have stopped rotating and/or began to tumble as soon as only two months following perihelion, and will certainly reach this stage by early in the next apparition. Working backwards in time, Tuttle-Giacobini-Kresak would have been rotating near its rotational break-up velocity 3-4 orbits earlier, suggesting that its extreme 7-magnitude outburst observed in 2001 might have been caused by a partial fragmentation at that time, as might the pair of 1973 8-magnitude outbursts if there had been an earlier spin-down and spin-up cycle.

description: We investigate on the same footing the time-dependent electronic transport properties and vibrational dynamics of a molecular junction. We show that fluctuations of both the molecular vibron displacement and the electronic current across the junction undergo damped oscillations towards the steady-state. We assign the former to the onset of electron tunneling events assisted by vibron-emission. The time-dependent build-up of electron-hole correlations is revealed as a departure of the charge-transfer statistics from the generalized-binomial one after a critical time tc. The phonon-back action on the tunneling electrons is shown to amplify and accelerate this build-up mechanism.
The Classical Solution for the Bosonic String in the Presence of Three D-branes Rotated by Arbitrary SO(4) Elements

description: We consider the classical instantonic contribution to the open string configuration associated with three D-branes with relative rotation matrices in SO(4) which corresponds to the computation of the classical part of the correlator of three non Abelian twist fields. We write the classical solution as a sum of a product of two hypergeometric functions. Differently from all the previous cases with three D-branes, the solution is not holomorphic and suggests that the classical bosonic string knows when the configuration may be supersymmetric. We show how this configuration reduces to the standard Abelian twist field computation. From the phenomenological point of view, the Yukawa couplings between chiral matter at the intersection in this configuration are more suppressed with respect to the factorized case in the literature.

description: Coherent diffraction imaging (CDI) allows the retrieval of the structure of an isolated object, such as a macromolecule, from its diffraction pattern. CDI requires the fulfilment of two conditions: the imaging radiation must be coherent and the object must be isolated. We discuss that it is possible to directly retrieve the molecular structure from its diffraction pattern which was acquired neither with coherent radiation nor from an individual molecule, provided the molecule exhibits periodicity in one direction, as in the case of fiber diffraction. We demonstrate that by applying iterative phase retrieval methods to a fiber diffraction pattern, the repeating unit, that is, the molecule structure, can directly be reconstructed without any prior modeling. As an example, we recover the structure of the DNA double helix in three-dimensions from its two-dimensional X-ray fiber diffraction pattern, Photograph 51, acquired in the famous experiment by Raymond Gosling and Rosalind Franklin, at a resolution of 3.4 Angstrom.

description: The lattice parameters of MgB2 up to pressures of 8 GPa were determined using high-resolution x-ray powder diffraction in a diamond anvil cell. The bulk modulus, B0, was determined to be 151 +-5 GPa. Both experimental and first-principles calculations indicate nearly isotropic mechanical behavior under pressure. This small anisotropy is in contrast to the 2 dimensional nature of the boron pi states. The pressure dependence of the density of states at the Fermi level and a reasonable value for the average phonon frequency account within the context of BCS theory for the reduction of Tc under pressure.

description: We formulate the field equations for $SU(\infty)$ Einstein-Yang-Mills theory, and find spherically symmetric black-hole solutions. This model may be motivated by string theory considerations, given the enormous gauge symmetries which characterize string theory. The solutions simplify considerably in the presence of a negative cosmological constant, particularly for the limiting cases of a very large cosmological constant or very small gauge field. The situation of an arbitrarily small gauge field is relevant for holography and we comment on the AdS/CFT conjecture in this light. The black holes possess infinite amounts of gauge field hair, and we speculate on possible consequences of this for quantum decoherence, which, however, we do not tackle here.

Using standard junction conditions, we attach the general closed spherically symmetric dust metric to a spacetime satisfying all standard energy conditions but with a single point future c-boundary. The resulting Omega Point spacetime, which has NO event horizons, nevertheless has black hole type trapped surfaces and hence black holes. But since there are no event horizons, information eventually escapes from the black holes. We show that a scalar quintessence field with an appropriate exponential potential near the final singularity would give rise to an Omega Point final singularity.

The critical temperature and the gap in $C_v$ increase with the value of the parameter $q$ and become approximately constant for $q>3$.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The association of hematological parameters especially platelet parameters with disease severity in malaria is poorly understood. We aimed to characterize the platelet parameters across Plasmodium falciparum and Plasmodium vivax malaria stratified by severity and to elucidate the potential role of platelet parameters to predict disease severity. Individuals > 18 years, of either gender with microscopically proven symptomatic malaria were prospectively enrolled between October 2014 and August 2016 in a tertiary center in Manipal, India. Severity of malaria was defined as per the WHO definition. Among 159 patients, 32 (20.1%) had severe malaria. 116 (73%) had infection with P. vivax, 37 (23%) P. falciparum and 6 mixed infection. Thrombocytopenia was seen in 32 (86.4%) of P. falciparum and 105 (90.5%) of P. vivax malaria cases. Patients with renal failure (p=0.02), shock (p=0.04) and liver dysfunction (p<0.001) had significantly lower platelet count compared to those who did not. Admission platelet count of 50,000 cell/mm3 had a sensitivity and specificity of 65.6% and 70.6% respectively, to discriminate severe malaria. A plateletcrit of 0.05% had a sensitivity and specificity of 65.6 % and of 70.6% respectively. Thrombocytopenia was seen in 89.3% of malaria cases due to both P. vivax and P. falciparum. Platelet count and plateletcrit could be used as markers of disease severity. P. vivax malaria which has been traditionally regarded as ‘benign’ can be as sinister and menacing as P. falciparum malaria and hence warrants equal attention. Unnecessary transfusion of platelets should be avoided.

description: The widespread adoption of continuously connected smartphones and tablets developed the usage of mobile applications, among which many use location to provide geolocated services. These services provide new prospects for users: getting directions to work in the morning, leaving a check-in at a restaurant at noon and checking next day's weather in the evening are possible right from any mobile device embedding a GPS chip. In these location-based applications, the user's location is sent to a server, which uses them to provide contextual and personalised answers. However, nothing prevents the latter from gathering, analysing and possibly sharing the collected information, which opens the door to many privacy threats. Indeed, mobility data can reveal sensitive information about users, among which one's home, work place or even religious and political preferences. For this reason, many privacy-preserving mechanisms have been proposed these last years to enhance location privacy while using geolocated services. This article surveys and organises contributions in this area from classical building blocks to the most recent developments of privacy threats and location privacy-preserving mechanisms. We divide the protection mechanisms between online and offline use cases, and organise them into six categories depending on the nature of their algorithm. Moreover, this article surveys the evaluation metrics used to assess protection mechanisms in terms of privacy, utility and performance. Finally, open challenges and new directions to address the problem of computational location privacy are pointed out and discussed.

Urban Meta(na)morphosis

Publisher: name: AIS - Architecture Image Studies

description: The present research explores the use of the art practices in “no-places” as an instrument of urban regeneration. “No-places” are meant as architectural and urban spaces where people perceive to be in a decayed and anonymous areas, without identity and ties with the territory due to their shapes and their ways of fruition. The goal is to transform them into ‘new places’, creating a different relationship between people and spaces. This is achieved without structural and architectural measures, but modifying those aspects concerning the perception, orientation and recognition to have an impact on the fruition and on the sense of belonging to the place. In particular, research focuses on the anamorphic artistic installations; anamorphosis is a geometrical process of optical illusion based on a distorted projection that enables the recognition of the original image watching it from a specific point of view. The enigmatic and fragmented labyrinth of signs becomes understandable for the observer only when he recomposed it with his eyes and his movement, thereby contributing to define new perception and use of the space. In the first part of the text we analyze some installations that use the anamorphosis as a tool of urban acupuncture; in the second part, the Boscoreale railway station constitutes the case study for the application of anamorphosis to a “no-place” of the urban mobility.

description: By exploiting the mathematical analogy between the propagation of sound in a non-homogeneous potential flow and the propagation of a scalar field in a background gravitational field, various wave ``energy'' and wave ``momentum'' conservation laws are established in a systematic manner. In particular the acoustic energy conservation law due to Blokhintsev appears as the result of the conservation of a mixed co- and contravariant energy-momentum tensor, while the exchange of relative energy between the wave and the mean flow mediated by the radiation stress tensor, first noted by Longuet-Higgins and Stewart in the context of ocean waves, appears as the covariant conservation of the doubly contravariant form of the same energy-momentum tensor.

description: This article’s title follows a realization, in practice, of the tendency of eye- dominance in vision. The realization comes through a process of drawing in- situ around Hoamji Lake in Chungu, South Korea, written commentary on the drawings themselves as part of the in-situ experience, and more analytical reflection after the event. The process was repeated on the basis that experience would thereby accrue and deepen. The experiential component of the drawings, made in response to the question of how drawing on site, can inform how one thinks about place and space and how this adds authenticity to the visualization of place. By way of updating a revision of an earlier published article, there is some reference to the author’s present involvement in architecture in an educational capacity. The drawings, despite their landscape reference, are relevant in their attempt to capture movement and in their process to a prospective studio project with architecture students. Written reflection on the drawings concerns the interrelationship of drawing from observable phenomena and visual sensory perception. The activity itself, of drawing, enables the latter’s consideration, and such a focus in turn informs how the drawings are made, appear, and comment on the in-situ location. The article’s theoretical markers concern aspects of sensory cognition and phenomenological theory, particularly in the context of articulation of space.

Concrete Poiētics
Creators: name: Twose, Simon
Publisher: name: AIS - Architecture Image Studies

description: This paper reports on an experimental drawing installation that is part of a sequence of art works radicalising architectural drawing: Drawing in the Expanded Field. Concrete Drawing was shown at Adam Art Gallery | Te Pātaka Toi, Wellington, Aotearoa New Zealand (2015), and at Pallazo Mora, XV Venice Architecture Biennale, Venice, Italy (2016). The work explored architecture in the space between drawing and building and sought to capture a shared atmosphere, merging the implacable materiality of built space with the indeterminate, open poiēsis of a sketch. Concrete Drawing was a large 1:1 sketch of a single wall surface, cast in two tonnes of concrete and laid horizontally in the gallery. The work intensified many poiētic acts in drawing and recorded them in the wall’s surface, which then engaged viewers in the installation. Small scale wall elements swarmed over the larger surface, alluding to the act of turning a model in the hands while designing. These arrays of miniature walls prompted viewers to move around the installation and bodily repeat the performance, mapping the dynamic space of drawing with that of the built. The research draws from literature discussing the power of openness and indeterminacy in drawing, ideas on materiality, and the shared influence of human and non-human feedback. Concrete Drawing contributes to an expanded field of drawing through the pursuit of a sfumato architecture, where drawing and building are in subtle vibration. The research prompts questions about the finality and fixity of architecture, proposing it instead as an open, sketch-like phenomenon - a habitable drawing.

description: We demonstrate that the multi-top productions efficiently probe the CP-property of top-Higgs interaction and the Higgs-boson width at the LHC. The four top-quark production alone can exclude a purely CP-odd top-quark Yukawa coupling at the 13~TeV LHC with an integrated luminosity of $430~{\rm fb}^{-1}$, regardless the size of the Yukawa coupling. Combining the single Higgs-boson production, the $t\bar{t}H$ associated production and the four top-quark production, we show that the CP-phase of the top-quark Yukawa coupling and the Higgs-boson width can be stringently bounded at the LHC with integrated luminosities of $300~{\rm fb}^{-1}$ and $3000~{\rm fb}^{-1}$.

description: The spin-gap phase of the one-dimensional t-J-J' model is studied by the level-crossing of the singlet and the triplet excitation spectra. The phase boundary obtained between the Tomonaga-Luttinger and the spin-gap phases is remarkably consistent with the analytical results at the $J,J'\to 0$ and the low-density limits discussed by Ogata et al. The spin-gap phase has a single domain in the phase diagram even if the spin gap opens at half-filling. The phase boundary coincides with the $K_ρ=1$ line where the Tomonaga-Luttinger liquid behaves as free electrons, in the low-density region. The relation between our method and the solution of the two-electron problem is also discussed.
