description: The Department of Defense (DoD) established the Joint Artificial Intelligence Center (JAIC) and later consolidated it into the Chief Digital and Artificial Intelligence Office (CDAO) to accelerate AI adoption across the military. However, structural misalignment, bureaucratic inertia, cultural resistance, and limited enforcement power undermined their effectiveness. Despite receiving Congressional funding, JAIC and CDAO struggled to integrate artificial intelligence (AI) into military operations as a result of fragmented governance, inter-service rivalries, and an absence of direct control over AI investments. Bureaucratic layers expanded, and “flyaway” teams did not have the authority or resources to deploy operational capacities. Additionally, cultural friction led to resistance from military branches while high attrition rates weakened institutional knowledge. This paper distills key lessons from JAIC and CDAO to guide the design and execution of future government units, ensuring they are strategically positioned, effectively governed, and empowered to drive lasting impact.

description: In dynamical systems governed by differential equations, a guarantee that trajectories emanating from a given set of initial conditions do not enter another given set can be obtained by constructing a barrier function that satisfies certain inequalities on phase space. Often these inequalities amount to nonnegativity of polynomials and can be enforced using sum-of-squares conditions, in which case barrier functions can be constructed computationally using convex optimization over polynomials. To study how well such computations can characterize sets of initial conditions in a chaotic system, we use the undamped double pendulum as an example and ask which stationary initial positions do not lead to flipping of the pendulum within a chosen time window. Computations give semialgebraic sets that are close inner approximations to the fractal set of all such initial positions.

description: In this paper, a novel adaptive smooth disturbance observer-based fast finite-time adaptive backstepping control scheme is presented for the attitude tracking of the 3-DOF helicopter system subject to compound disturbances. First, an adaptive smooth disturbance observer (ASDO) is proposed to estimate the composite disturbance, which owns the characteristics of smooth output, fast finite-time convergence, and adaptability to the disturbance of unknown derivative boundary. Then, a finite-time backstepping control protocol is construct to drive the elevation and pitch angles to track reference trajectories. To tackle the "explosion of complexity" and "singularity" problems in the conventional backstepping design framework, a fast finite-time command filter (FFTCF) is utilized to estimate the virtual control signal and its derivative. Moreover, a fractional power-based auxiliary dynamic system is introduced to compensate the error caused by the FFTCF estimation. Furthermore, an improved fractional power-based adaptive law with the $σ$-modification term is designed to attenuate the observer approximation error, such that the tracking performance is further enhanced. In terms of the fast finite-time stability theory, the signals of the closed-loop system are all fast finite-time bounded while the attitude tracking errors can fast converge to a sufficiently small region of the origin in finite time. Finally, a contrastive numerical simulation is carried out to validate the effectiveness and superiority of the designed control scheme.

description: Formal semantics is a method of studying meaning that has roots in logic, linguistics, for a language. It is normally based on the inference rules and some mathematical logical systems in-order to overcome ambiguities. A type system defines the structure of a program. It is a mechanism for defining, detecting, and preventing illegal program states. This mechanism works by defining and applying some specific constraints or conditions. The constraint definitions are types, and the conditional applications are usages of types. Example: identifier initialisation. In this paper, C Programming language has been studied to explain the formal specification of semantics and typing rules for various constructs.
The Story in Your Eyes: An Individual-difference-aware Model for Cross-person Gaze Estimation

description: We propose a novel method on refining cross-person gaze prediction task with eye/face images only by explicitly modelling the person-specific differences. Specifically, we first assume that we can obtain some initial gaze prediction results with existing method, which we refer to as InitNet, and then introduce three modules, the Validity Module (VM), Self-Calibration (SC) and Person-specific Transform (PT)) Module. By predicting the reliability of current eye/face images, our VM is able to identify invalid samples, e.g. eye blinking images, and reduce their effects in our modelling process. Our SC and PT module then learn to compensate for the differences on valid samples only. The former models the translation offsets by bridging the gap between initial predictions and dataset-wise distribution. And the later learns more general person-specific transformation by incorporating the information from existing initial predictions of the same person. We validate our ideas on three publicly available datasets, EVE, XGaze and MPIIGaze and demonstrate that our proposed method outperforms the SOTA methods significantly on all of them, e.g. respectively 21.7%, 36.0% and 32.9% relative performance improvements. We won the GAZE 2021 Competition on the EVE dataset. Our code can be found here https://github.com/bjj9/EVE_SCPT.

description: Context. The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) observatory combines a large field of view and collecting area in the energy range $\sim$0.2 to $\sim$8.0 keV with the capability to perform uniform scanning observations of large sky areas. Aims. SRG/eROSITA performed scanning observations of the $\sim$140 square degrees eROSITA Final Equatorial Depth Survey (eFEDS) field as part of its performance verification phase. The observing time was chosen to slightly exceed the depth of equatorial fields after the completion of the eROSITA all-sky survey. We present a catalog of detected X-ray sources in the eFEDS field providing source positions and extent information, as well as fluxes in multiple energy bands and document a suite of tools and procedures developed for eROSITA data processing and analysis, validated and optimized by the eFEDS work. Methods. A multi-stage source detection procedure was optimized and calibrated by performing realistic simulations of the eROSITA eFEDS observations. We cross-matched the eROSITA eFEDS source catalog with previous XMM-ATLAS observations, confirming excellent agreement of the eROSITA and XMM-ATLAS source fluxes. Result. We present a primary catalog of 27910 X-ray sources, including 542 with significant spatial extent, detected in the 0.2-2.3 keV energy range with detection likelihoods $\ge 6$, corresponding to a (point source) flux limit of $\approx 6.5 \times 10^{-15}$ erg/cm$^2$/s in the 0.5-2.0 keV energy band (80% completeness). A supplementary catalog contains 4774 low-significance source candidates with detection likelihoods between 5 and 6. In addition, a hard band sample of 246 sources detected in the energy range 2.3-5.0 keV above a detection likelihood of 10 is provided. The dedicated data analysis software package, calibration database, and calibrated data products are described in an appendix.

Vincentown Formation

description: The Late Paleocene Vincentown Formation in New Jersey has a fossil fauna rich in invertebrates, especially bryozoans, echinoids and foraminifers. Vertebrate fossils, from the Vincentown Formation, include chondrichtyan teeth, bird bones and isolated snake remains. Additionally, the remains of several longirostrine crocodylians have been reported, including ‘Crocodilus’ clavirostris Morton 1845, Thoracosaurus neocesariensis(deKay 1842) and Eosuchus minor (Marsh 1870). Here we report on the recovery, by the New Jersey State Museum in 2016, of a nearly complete mandible and associated material of a very large longirostrine crocodylian (NJSM 24294) from the upper part of the Vincentown Formation of Burlington County, New Jersey. This is an on-going project and this report is meant as a status report. A complete description of the elements and phylogenetic analysis will be published at a future date.

description: SN 1987A is the closest observed supernova in the last four centuries and provides a unique opportunity to witness the birth and evolution of a supernova remnant. The source has been monitored by XMM Newton EPIC-pn from 2007--2020. SRG/eROSITA also observed the source during its commissioning phase and the first light in Sept. and Oct. 2019. We investigated the spectral and flux evolution of SN 1987A in X-rays over the last fourteen years up to Nov. 2020 using XMM-Newton and eROSITA observations. We performed a detailed spectral analysis using a three-component plane-parallel shock model and analysed and modelled the EPIC-pn monitoring and eROSITA observations in a consistent manner. This paper reports a complete and most up to date flux evolution of SN 1987A in the soft (0.5-2 keV) and hard (3-10 keV) X-ray band. The flux in the soft band flattened around 9424 d and then displayed a turnover between 10142-10493 d after which it showed a continued decline. Around the same time, a break in the hard-band flux time evolution slope was detected. This implies that the blast wave has now passed beyond the dense structures of the equatorial ring and is expanding further into more tenuous circumstellar medium. The temporal evolution of the normalizations of the three shock components match well the results of hydrodynamical simulations predicting a blue supergiant progenitor scenario. The trend at recent epochs indicate that the emission caused by the forward shock after leaving the equatorial ring and by the reverse shock in the ejecta is becoming more dominant now. The elemental abundances in the hot plasma component are significantly higher than those in the `cooler' one, indicating its origin from the reverse shock propagating into the ejecta.

description: We report the identification and follow-up of the transient SRG 062340.2-265715 detected with both instruments on board the Spektrum-Roentgen-Gamma mission. Optical spectroscopy of the G=12.5 counterpart firmly classifies the object as a novalike cataclysmic variable (CV) at a distance of 495 pc. A highly significant TESS period of 3.941 hours, tentatively identified with the orbital period of the binary, could not be found when the object was reobserved with TESS two years later. The newer high-cadence TESS data revealed quasi-periodic oscillations around 25 min, while ground-based photometry indicated periodic variability at 32 min. Located in very sparsely populated regions of color-magnitude diagrams involving X-ray and optical magnitudes and colors, the new object could be an X-ray underluminous magnetic CV, an intermediate polar, or an overluminous nonmagnetic CV. The lack of uniquely identified spin and orbital periods prevents a final classification. The site of X-ray production in the system, L(X, bol) = 4.8 x 10^{32} erg/s, remains to be understood given its high variability on long and short timescales.

Elephants as refugees

description: Habitat loss and climate change are displacing animals at alarming rates. In response, authors in the humanities and the sciences have described animals rhetorically as ‘refugees’. Such a description implies a strong call to action.However, the term ‘refugee’ may serve as more than mere rhetoric, indicating in a more literal way the response most proper to some persecuted, traumatized and displaced animals, and prioritizing those animals.We test the claim that animals can be refugees using widely accepted criteria in the Refugee Convention. If refugees are those who, due to a well‐founded fear of persecution for reasons of their group identity, are unwilling or unable to avail themselves of the protection of their country, then some animals may be refugees. Recent behavioural research on African elephants Loxodonta africana demonstrates that many elephants meet the criteria, even without recourse to the claim that they are persons.We outline the essential requirements of an animal refugee policy. We find that current biodiversity conservation policy is likely inadequate to provide for animal refugees, although important lessons can be taken from the collective experience of conservation scientists and managers.An obligation to animal refugees poses new challenges, both theoretical and practical, for ecological restoration, conservation and human–animal relations.

description: Stellar activity is inherently time variable, therefore simultaneous measurements are necessary to study the correlation between different activity indicators. In this study we compare X-ray fluxes measured within the first all-sky survey conducted by the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) instrument on board the Spectrum-Roentgen-Gamma (SRG) observatory to Ca II H & K, excess flux measurements R+, using observations made with the robotic TIGRE telescope. We created the largest sample of simultaneous X-ray and spectroscopic Ca II H & K observations of late-type stars obtained so far, and in addition, previous measurements of Ca II H & K for all sample stars were obtained. We find the expected correlation between our log(L_X/L_bol) to log(R+) measurements, but when the whole stellar ensemble is considered, the correlation between coronal and chromospheric activity indicators does not improve when the simultaneously measured data are used. A more detailed analysis shows that the correlation of log(L_X/L_bol) to log(R+) measurements of the pseudo-simultaneous data still has a high probability of being better than that of a random set of non-simultaneous measurements with a long time baseline between the observations. Cyclic variations on longer timescales are therefore far more important for the activity flux-flux relations than short-term variations in the form of rotational modulation or flares, regarding the addition of "noise" to the activity flux-flux correlations. Finally, regarding the question of predictability of necessarily space-based log(L_X/L_bol) measurements by using ground-based chromospheric indices, we present a relation for estimating log(L_X/L_bol) from R+ values and show that the expected error in the calculated minus observed (C-O) log(L_X/L_bol) values is 0.35 dex.

description: We present the first X-ray detections of ultracool dwarfs (UCDs) from the first all-sky survey of the extended ROentgen Survey with an Imaging Telescope Array (eROSITA) onboard the Russian Spektrum-Roentgen-Gamma (SRG) mission. We use three publicly available input catalogs of spectroscopically confirmed UCDs and Gaia-selected UCD candidates that together comprise nearly 20000 objects. We first extracted all X-ray sources from the catalog of the first eROSITA survey, eRASS1, that have a UCD or candidate within three times their positional uncertainty. Then we examined all Gaia objects in the vicinity of these 96 X-ray sources and we associated them to the most plausible counterpart on the basis of their spatial separation to the X-ray position and their multiwavelength properties. This way we find 40 UCDs that have a secure identification with an X-ray source and 18 plausible UCD X-ray emitters. Twenty-one of these X-ray emitting UCDs have a spectroscopic confirmation, while the others have been selected based on Gaia photometry and we computed spectral types from the G-J color. The spectral types of the X-ray emitting UCDs and candidates range between M5 and M9, and the distances range from 3.5 to 190 pc. The majority of the UCDs from the eRASS1 sample show a ratio of X-ray to bolometric luminosity well above the canonical saturation limit of log (Lx/Lbol) ~ -3. For the two most extreme outliers, we showed through an analysis of the eRASS1 light curve that these high values are due to flaring activity. The X-ray spectra of the two brightest objects both reveal an emission-measure weighted plasma temperature of kT ~ 0.75 keV. These observations demonstrate the potential of eROSITA for advancing our knowledge on the faint coronal X-ray emission from UCDs by building statistical samples for which the average X-ray brightness, flares, and coronal temperatures can be derived.

description: We present the results of the first X-ray all-sky survey (eRASS1) performed by the eROSITA instrument on board the Spectrum-Roentgen-Gamma (SRG) observatory of the Sco-Cen OB association. Bona fide Sco-Cen member stars are young and are therefore expected to emit X-rays at the saturation level. The sensitivity limit of eRASS1 makes these stars detectable down to about a tenth of a solar mass. By cross-correlating the eRASS1 source catalog with the Gaia EDR3 catalog, we arrive at a complete identification of the stellar (i.e., coronal) source content of eROSITA\ in the Sco-Cen association, and in particular obtain for the first time a 3D view of the detected stellar X-ray sources. Focusing on the low-mass population and placing the optical counterparts identified in this way in a color-magnitude diagram, we can isolate the young stars out of the detected X-ray sources and obtain age estimates of the various Sco-Cen populations. A joint analysis of the 2D and 3D space motions, the latter being available only for a smaller subset of the detected stellar X-ray sources, reveals that the space motions of the selected population show a high degree of parallelism, but there is also an additional population of young, X-ray emitting and essentially cospatial stars that appears to be more diffuse in velocity space. Its nature is currently unclear. We argue that with our procedures, an identification of almost the whole stellar content of the Sco-Cen association will become possible once the final Gaia and eROSITA catalogs are available by the end of this decade. We furthermore call into question any source population classification scheme that relies on purely kinematic selection criteria.

description: The discovery that many classical novae produce detectable GeV $γ$-ray emission has raised the question of the role of shocks in nova eruptions. Here we use radio observations of nova V809 Cep (Nova Cep 2013) with the Jansky Very Large Array to show that it produced non-thermal emission indicative of particle acceleration in strong shocks for more than a month starting about six weeks into the eruption, quasi-simultaneous with the production of dust. Broadly speaking, the radio emission at late times -- more than a six months or so into the eruption -- is consistent with thermal emission from $10^{-4} M_\odot$ of freely expanding, $10^4$~K ejecta. At 4.6 and 7.4 GHz, however, the radio light-curves display an initial early-time peak 76 days after the discovery of the eruption in the optical ($t_0$). The brightness temperature at 4.6 GHz on day 76 was greater than $10^5 K$, an order of magnitude above what is expected for thermal emission. We argue that the brightness temperature is the result of synchrotron emission due to internal shocks within the ejecta. The evolution of the radio spectrum was consistent with synchrotron emission that peaked at high frequencies before low frequencies, suggesting that the synchrotron from the shock was initially subject to free-free absorption by optically thick ionized material in front of the shock. Dust formation began around day 37, and we suggest that internal shocks in the ejecta were established prior to dust formation and caused the nucleation of dust.

description: An outcrop of late Miocene lacustrine mudstone from the c.11 Ma Carina Rock Ignimbrite Formation, Whitianga Group, yielded an angiosperm-dominated leaf flora, here calledthe Kaimarama flora. Thirty-one dicot broadleaved angiosperm leaf morphotypes were differentiated from collections made from this flora, and leaf morphology-based methodsof paleoclimate analysis were applied. In addition, the Kaimarama flora includes monocot angiosperm leaf fragments, Phyllocladus, other podocarps, Araucariaceae leaves, leaflets of a likely Cupressaceae, fern fragments, seeds and fruits. Associated faunal remains are rare and currently only amount to one insect wing impression, a partial freshwater bivalve impression and insect damage on some of the leaves. A moderately diverse palynoflora in the associated sediments supports the presence of fern-dominated vegetation, perhaps a proximal wetland/open land environment and a mixed conifer- and Nothofagaceae-dominated forest. Myrtaceae-like remains are also common in the macrofossil assemblage but rare in the palynology assemblage. Despite attempts, identifiable cuticle has not yet been extractedfrom the leaves, so leaf-based taxonomic inferences are based only on macromorphology and are therefore tentative.Leaf morphology-based paleoclimate analysis of the Kaimarama flora (using the CLAMP [Climate Leaf Analysis Multivariate Program] method) produced temperature estimates consistent with a seasonal temperate climate. Both CLAMP and Bioclimatic Analysis, a nearest-living-relative-based approach, produced estimates of mean annual temperature (MAT) similar to, or a little cooler than, the ~14°C MAT of Kaimarama today, with rainfall in the order of 150 cm during the growing season. Several other late Miocene floras are known from both North and South Island but only two have previously been analysed using leaf morphology-based methods of climate analysis, both from near Dunedin, the Kaikorai flora and the Double Hill flora. Paleoclimate estimates from the Kaimarama flora are broadly consistent with the temperate climate estimates derived from the Kaikorai flora. (auths)

description: A novel approach to reconstruct inclusive $\bar{B} \to X_{s} \ell^{+}\ell^{-}$ decays is presented. The method relies on isopsin symmetry to extrapolate the semi-inclusive signature $X_{b}\to K^{+} \ell^{+}\ell^{-} X$ to the fully inclusive rate in $B^{+}$ and $B^{0}$ decays. We investigate the possibility to measure branching fractions and other observables such as lepton universality ratios and $CP$ asymmetries. As a proof of concept, fast simulation is used to compare the $X_{b}\to K^{+} \ell^{+}\ell^{-} X$ signature with a fully inclusive approach. Several experimental advantages are seen which have the potential to make measurements of inclusive $\bar{B} \to X_{s} \ell^{+}\ell^{-}$ decays tractable at a hadron collider.

description: Bounded plasmas are characterized by a rapid but smooth transition from quasi-neutrality in the volume to electron depletion close to the electrodes and chamber walls. The thin non-neutral region, the boundary sheath, comprises only a small fraction of the discharge domain but controls much of its macroscopic behavior. Insights into the properties of the sheath and its relation to the plasma are of high practical and theoretical interest. The recently proposed smooth step model provides a closed analytical expression for the electric field in a planar, radio-frequency modulated sheath. It represents (i) the space charge field in the depletion zone, (ii) the generalized Ohmic and ambipolar field in the quasi-neutral zone, and (iii) a smooth interpolation for the transition in between. This investigation compares the smooth step model with the predictions of a more fundamental particle-in-cell/Monte Carlo collisions simulation and finds good quantitative agreement when the assumed length and time scale requirements are met. A second simulation case illustrates that the model remains applicable even when the assumptions are only marginally fulfilled

description: The fusion probability for the production of superheavy nuclei in cold fusion reactions was investigated and compared with recent experimental results for $^{48}$Ca, $^{50}$Ti, and $^{54}$Cr incident on a $^{208}$Pb target. Calculations were performed within the fusion-by-diffusion model (FbD) using new nuclear data tables by Jachimowicz et al. It is shown that the experimental data could be well explained within the framework of the FbD model. The saturation of the fusion probability at bombarding energies above the interaction barrier is reproduced. It emerges naturally from the physical effect of the suppression of contributions of higher partial waves in fusion reactions and is related to the critical angular momentum. The role of the difference in values of the rotational energies in the fusion saddle point and contact (sticking) configuration of the projectile-target system is discussed.

Prejudice in a sample of DC-based University International Students: Examining the role of Acculturative Stress and Perceived Discrimination
Creators: name: Perez, Alana
Publisher: name: American University
Year: 2023

description: Previous research has focused on studying international students as being on the receiving end of prejudice. By using a series of self-report questionnaires, this study sought to explore international students' prejudicial attitudes towards the host (U.S.) culture. Two factors were examined that could shed light on this phenomenon, first, stress that stems from trying to acculturate to the US culture and second, having lived through experiences of discrimination. In accordance with the predictions, a positive relationship was found between acculturation stress and prejudice, as well as between perceived discrimination and prejudice. This last relationship was found to be moderated by the student's motivation to respond in a non-prejudiced way; among those highly motivated to respond without prejudice, those who reported higher levels of perceived discrimination also reported the highest levels of prejudice. Neuroticism was not found to moderate the discrimination-prejudice relationship. Implications, limitations and future research directions are discussed.
The Patron State: The Processes and Dialectics of Cultural Policy in Morocco (21st Century Morocco: Identity Manifestations in Art, Culture and Language - Ibn Tofail University, Kenitra, Morocco)

description: As a field of critical inquiry, Cultural Studies has engaged with the political primarily at the level of cultural politics (the politics of producing and consuming culture) and has all too often neglected the implications of the dominant political culture (the culture of politics). Political culture, in this context, is used in reference to a set of attitudes, beliefs, and sentiments which give order and meaning to a political process (i.e., political knowledge). This knowledge encompasses political ideals, collective histories, conflicting narratives, and operating norms of polity, which thus provide the political system with its distinctive, underlying assumptions and rules (i.e., political behaviour). The present paper addresses this lacuna by exploring the implications of the dominant political culture in Morocco on the governance and management of culture and the arts. Recent policy developments in Morocco regarding the field of culture have revealed different challenges relative to the sort of administrative mechanisms and managerial practices that inform the implementation of cultural policies. These challenges mostly concern the extent to which cultural policy programmes (e.g., Cultural Morocco 2015-2021) are effective enough to fulfil their objectives.A considerable part of the growing literature in cultural policy research has emphasised the role of the wider political culture in the formulation of the national cultural policy. The aim of this paper is to provide a critical understanding of the system of cultural patronage as a distinctive mode of governing the field of culture in Morocco. It shows how certain aspects of the political knowledge and political behaviour relate in an interactive blend of conflict and continuity. While the concerns of the current conference relate to the themes of art, culture, language, and Identity, the intention of this paper is to explore the duality of culture and politics in the context of current public policy changes as well as the processes and structures that are mobilised for the management of public culture.The implications of the present paper in terms of theory and methodology are as follows:The integration of cultural policy research into cultural studiesThe inadequacy of textual analysis as a dominant approach in cultural studies to grapple with issues regarding the governmental intervention in the field of cultureThe new policy dynamics are fundamental to the understanding of the relations between culture and powerA more operational definition of ‘culture’ should acknowledge the governmental instrumentalisation of and intervention into the field of culture

description: The Flux Observations of Carbon from an Airborne Laboratory (FOCAL) project is a cooperative effort among the Anderson Group from Harvard University, Aurora Flight Sciences, and NOAA's Atmospheric Turbulence and Diffusion Division (NOAA/ATDD) to add scientific instruments to a Diamond Aircraft DA-42 Twin Star aircraft to measure fluxes of CO₂ and CH₄ in the planetary boundary layer. The work, funded by the National Science Foundation in 2012, uses the Anderson Group's Integrated Cavity-Output Spectroscopy (ICOS) instrument suite to measure concentrations and isotopologues of CO₂ and CH₄, NOAA/ATDD's Best Airborne Turbulence (BAT) probe to measure atmospheric turbulence in 3-dimensions, and Aurora Flight Sciences' DA-42 Twin Star aircraft to carry the complete instrument package. The DA- 42 collected 36.9 hours of research data based from Deadhorse Airport in Prudhoe Bay, Alaska in August, 2013. A flight track was created to compare the CO₂ and CH₄ flux measurements made by instruments aboard the DA-42 against a groundbased tower which made simultaneous CO₂ and CH₄ flux measurements. Flight tracks were then expanded to measure fluxes far beyond the tower comparison area. Tracks were flown over inland melt-pond lakes and the Arctic Ocean to monitor CH₄ concentrations and fluxes, as well as to compare coincident measurements of bulk water-column and in-situ tundra flux measurements made by the Naval Research Laboratory (NRL). Tracks were also flown to characterize the background CO₂ and CH₄ concentrations around the Prudhoe Bay oil fields. This report describes the NOAA/ATDD BAT probe instrumentation and the August 2013 Alaska flight campaign.

description: We study the Kaluza-Klein inspired Brans-Dicke model with barotropic matter. Following from our previous work, the traditional Kaluza-Klein gravity action is introduced with an additional scalar field and 2 gauge fields. The compactification process results in a Brans-Dicke model with a dilaton coupled to the tower of scalar fields whereas a gauge field from 5-dimensional metric forms a set of mutually orthogonal vectors with 2 additional gauge fields. The barotropic matter is then introduced to complete a realistic set up. To demonstrate the analytical solutions of the model, we consider the case in which only 2 lowest modes becoming relevant for physics at low scale. After derivation, equations of motion and Einstein field equations form a set of autonomous system. The dynamical system is analysed to obtain various critical points. Interestingly, by only inclusion of barotropic matter, the model provides us the critical points which capable of determining the presences of dark matter, dark energy and phantom dark energy.

description: This paper presents a partial equilibrium model of two closely related industries: an
intermediate good in the upstream and a final good in the downstream. Unlike other
partial equilibrium models that focus on one specific country, such as a model of the
U.S. market, this model allows for more than one country market. The model can be
used to analyze how a tariff on intermediate imports can affect final good domestic
production. It can also be used to analyze how the removal of trade barriers on intermediates between two countries can affect both imports and exports in intermediate
and final goods markets.
