description: The advancement of terrestrial networks has improved communication services for users in densely-populated areas, outpacing improvements in rural regions. The projected surge in connected devices in upcoming networks entails that the lack of rural and remote connectivity is limiting emerging applications like digital agriculture and intelligent transportation. Thus, expanding rural and remote wireless connectivity requires addressing the limitations of existing terrestrial infrastructure. In this work, we explore two emerging solutions aimed at enhancing wireless connectivity in rural and remote regions. The first approach considers non-terrestrial networks as an alternative to existing terrestrial technology. Specifically, a vertically-integrated, multi-layered architecture involving unmanned aerial vehicles, high-altitude platforms, and satellites serves as complementary elements, offering diverse pathloss, delay, data rates, and network backbone proximity. We address issues such as multi-hop performance degradation, node mobility, placement, and power distribution to optimize network design. The second approach focuses on wireless-powered communication networks, particularly backscatter communications, to overcome challenges associated with the timely data collection of emerging rural applications such as precision agriculture. We utilize ambient orthogonal frequency division multiplexing (OFDM) signals from cellular base stations to facilitate low-power, low-cost, and real-time data collection while eliminating the need for dedicated radio-frequency emitters. Non-coherent detection and modulation schemes are employed to obviate the necessity for accurate channel state information at the power-limited sensors and reader devices. Moreover, we introduce techniques for simultaneous sensor multiplexing by leveraging OFDM signal structure. Our approaches demonstrate substantial improvements in communication performance, offering versatile, scalable, and cost-effective solutions for rural and remote areas.

description: The chiral langasite Ba$\_3$NbFe$\_3$Si$\_2$O$\_{14}$ is a multiferroic compound. While its magnetic order below T$\_N$=27 K is now well characterised, its polar order is still controversial. We thus looked at the phonon spectrum and its temperature dependence to unravel possible crystal symmetry breaking. We combined optical measurements (both infrared and Raman spectroscopy) with ab initio calculations and show that signatures of a polar state are clearly present in the phonon spectrum even at room temperature. An additional symmetry lowering occurs below 120~K as seen from emergence of softer phonon modes in the THz range. These results confirm the multiferroic nature of this langasite and open new routes to understand the origin of the polar state.

Zoobank: 2C86EAF9-4708-4674-88BA-B76BDD38B95F Diagnosis — Transeius mickaeli Kreiter n. sp. belongs also to the subfamily Amblyseiinae (see above description of T. maelliae n. sp.), to the tribe Amblyseiini (see above), to the subtribe Amblyseiina (see above), to the genus Transeius (see above) (Chant and McMurtry 2007) and to the species group bellottii and to the species subgroup bellottii (Chant and McMurtry 2004a). Transeius mickaeli n. sp. is different from T. maelliae n. sp. described above, by several characters indicated above in the description of T. maelliae (see diagnosis of T. maelliae). In this subgroup bellottii, the closest species of T. mickaeli n. sp. is Transeius quichua (McMurtry and Moraes). Transeius mickaeli n. sp. differs however from T. quichua in having 7 solenostomes instead of 6, longer setae j1, s4, S2, Z4, and StIV and shorter setae Z5, peritreme reaching j1 and not between j1 and j3, reticulations of the dorsal shield, slight reticulations of the sternal and moreover of the ventrianal shields in the female and male, shape of the spermatheca which is saccular and bell-shaped in the new species and more cup shaped, pocular and open (Denmark and Evans 2011) in T. quichua and the insertion of gv3 further to JV2 insertion in the new species (gv3 are very close to setae JV2 positions in T. quichua).

description: Based on the approach of flow distances, the international trade flow system is studied from the perspective of multi-layer flow network. A model of multi-layer flow network is proposed for modelling and analyzing multiple types of flows in flow systems. Then, flow distances are introduced, and symmetric minimum flow distance is presented. Subsequently, we discuss the establishment of the multi-layer flow networks of international trade from two coupled viewpoints, i.e., the viewpoint of commodity flow and that of money flow. Thus, the multi-layer flow networks of international trade is explored. First, trading "trophic levels" are adopted to depict positions that economies occupied in the flow network. We find that the distributions of trading "trophic levels" have the similar clustering pattern for different types of commodity, and there are some regularities between money flow network and commodity flow network. Second, we find that active and competitive countries trade a wide spectrum of products, while inactive and underdeveloped countries trade a limited variety of products. Besides, some abnormal countries import many types of goods, which the vast majority of countries do not need to import. It may indicate an abnormal economic status. Third, harmonic node centrality is proposed and we find the phenomenon of centrality stratification. It means that competitive countries tend to occupy the central positions in the trading of a large variety of commodities, while underdeveloped countries likely in the peripheral positions in the trading of their limited varieties of products. Fourth, we find that manufactured products have significant larger mean first-passage flow distances from the source to the sink than that of primary products.

description: The history of Colombia has been defined by the paradox of the coexistence of violence and economic growth. While the economy of the country has grown almost uninterruptedly since the middle of the 20th century, in 2019 the state was still not fully capable of reasserting its presence nor of providing justice or security for all of its citizens across its territory. This chapter analyses the paradox of the coexistence of armed violence and economic growth in Colombia, in which parts of the elite sections of the country benefit by the lack of security and justice. Violence is good for business, although not good for statehood.
From the End of History to the End of Humanity: Naturalized Justification in the Evaluation of Possible Futures
Creators: name: Kowalski, Ken Cai
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: From Thatcher and Fukuyama to Jameson and the Frankfurt School, observers of contemporary capitalism have long proclaimed the death of the utopian ideal. Failed experiments with noncapitalist society continue to fuel speculation about whether desirable alternatives to capitalism can exist even in potentiality. This study traces the myopic scope of imagined possible futures through the popular use of “naturalizing concepts” that help sustain a coherent social reality for American capitalism. Seventy-two North Carolinians from varied backgrounds convened in twelve focus groups to evaluate the plausibility and desirability of three hypothetical depictions of the far-future United States: an egalitarian society with no class divisions, Keynesian social democracy, and radical free-market capitalism. Participants overwhelmingly condemned the egalitarian scenario as a violation of natural order, especially “human nature” conceived as both universally acquisitive and uniquely individuated. This contradictory conception of human nature usefully interprets and naturalizes mutual experience of market-driven stratification.
Three-Dimensional MHD Magnetic Reconnection Simulations with Finite Guide Field: Proposal of the Shock-Evoking Positive-Feedback Model

description: Using a three-dimensional magnetohydrodynamic model, we simulate the magnetic reconnection in a single current sheet. We assume a finite guide field, a random perturbation on the velocity field and uniform resistivity. Our model enhances the reconnection rate relative to the classical Sweet-Parker model in the same configuration. The efficiency of magnetic energy conversion is increased by interactions between the multiple tearing layers coexisting in the global current sheet. This interaction, which forms a positive-feedback system, arises from coupling of the inflow and outflow regions in different layers across the current sheet. The coupling accelerates the elementary reconnection events, thereby enhancing the global reconnection rate. The reconnection establishes flux tubes along each tearing layer. Slow-mode shocks gradually form along the outer boundaries of these tubes, further accelerating the magnetic energy conversion.Such positive-feedback system is absent in two-dimensional simulation, three-dimensional reconnection without a guide field and a reconnection under a single perturbation mode. We refer to our model as the "shock-evoking positive-feedback" model.

description: We study the structure of the eigenstates and the dynamics of a system that undergoes an excited state quantum phase transition (ESQPT). The analysis is performed for two-level pairing models characterized by a U(n+1) algebraic structure. They exhibit a second order phase transition between two limiting dynamical symmetries represented by the U(n) and SO(n+1) subalgebras. They are, or can be mapped onto, models of interacting bosons. We show that the eigenstates with energies very close to the ESQPT critical point, E_{ESQPT}, are highly localized in the U(n)-basis. Consequently, the dynamics of a system initially prepared in a U(n)-basis vector with energy close to E_{ESQPT} may be extremely slow. Signatures of an ESQPT can therefore be found in the structures of the eigenstates and in the speed of the system evolution after a sudden quench. Our findings can be tested experimentally with trapped ions.

description: Ueckermannseius nesiotus (Ueckermann & Kreiter) Typhlodromalus nesiotus Ueckermann & Kreiter 2002: 343. Ueckermannseius nesiotus Chant & McMurtry, 2005b: 203; 2007: 115. This species was described as Typhlodromalus nesiotus Ueckermann and Kreiter in Kreiter et al. (2002) but as all setae are short to minute, the setae Z4 are not as long as distance between their base and that of setae S4 and the dorsal shield is smooth except some anterolateral striations, it belongs to the genus Ueckermannseius (Chant and McMurtry 2005b). This species has never been recorded from other countries or record again in La Réunion since its description. The biology of this species remains totally unknown. This is the first new record since the original description in 2002. Specimens examined: two ♀♀ in total, both measured. Petite Île – Piton Bloc, Yébo Luguy farm (aasl 973 m, Long 55°34’64” E, Lat 21°18’64” S), 1 ♀ on R. raphanistrum, 9/12/2015; Forêt de Sans Souci – Ilet Alcide, (aasl 1452 m, Long 55°22’07” E, Lat 21°01’17” S), 1 ♀ on Hypericum lanceolatum Lam., 18/11/2018. Remarks: the two females collected and measured during this study (Table 26) slightly differ from females measured by Kreiter et al. (2002). Dorsal shield dimensions are greater by 15–26%, length and width of the sternal shield are greater by 25 and 20% respectively, and the length of JV5 is greater by 60%.

description: We present Star Formation Histories (SFHs) for a sample of 104 massive (stellar mass M > 10$^{10}$ M$_{\odot}$) quiescent galaxies (MQGs) at $z$=1.0-1.5 from the analysis of spectro-photometric data from the SHARDS and HST/WFC3 G102 and G141 surveys of the GOODS-N field, jointly with broad-band observations from ultraviolet (UV) to far-infrared (Far-IR). The sample is constructed on the basis of rest-frame UVJ colours and specific star formation rates (sSFR=SFR/Mass). The Spectral Energy Distributions (SEDs) of each galaxy are compared to models assuming a delayed exponentially declining SFH. A Monte Carlo algorithm characterizes the degeneracies, which we are able to break taking advantage of the SHARDS data resolution, by measuring indices such as MgUV and D4000. The population of MQGs shows a duality in their properties. The sample is dominated (85%) by galaxies with young mass-weighted ages, tM $$ 1.0, when our galaxies were 0.5-1.0 Gyr old. According to these SFHs, all the MQGs experienced a Luminous Infrared Galaxy (LIRG) phase that lasts for $\sim$ 500 Myr, and half of them an Ultra Luminous Infrared Galaxy (ULIRG) phase for $\sim$ 100 Myr. We find that the MQG population is almost assembled at $z$ $\sim$ 1, and continues evolving passively with few additions to the population.

description: We investigate the impact of tidal interactions, before any mass transfer, on various properties of the stellar models. We study the conditions for obtaining homogeneous evolution triggered by tidal interactions, and for avoiding any Roche lobe overflow during the Main-Sequence phase. We consider the case of rotating stars computed with a strong coupling mediated by an interior magnetic field. In models without any tidal interaction (single stars and wide binaries), homogeneous evolution in solid body rotating models is obtained when two conditions are realized: the initial rotation must be high enough, the loss of angular momentum by stellar winds should be modest. This last point favors metal-poor fast rotating stars. In models with tidal interactions, homogeneous evolution is obtained when rotation imposed by synchronization is high enough (typically a time-averaged surface velocities during the Main-Sequence phase above 250 km s$^{-1}$), whatever the mass losses. In close binaries, mixing is stronger at higher than at lower metallicities. Homogeneous evolution is thus favored at higher metallicities. Roche lobe overflow avoidance is favored at lower metallicities due to the fact that stars with less metals remain more compact. We study also the impact of different processes for the angular momentum transport on the surface abundances and velocities in single and close binaries. In models where strong internal coupling is assumed, strong surface enrichments are always associated to high surface velocities in binary or single star models. In contrast, models computed with mild coupling may produce strong surface enrichments associated to low surface velocities. Close binary models may be of interest for explaining homogeneous massive stars, fast rotating Wolf-Rayet stars, and progenitors of long soft gamma ray bursts, even at high metallicities.

description: We are the first to show with clear experimental results that photons that have energy lower than the transition energy between quantum dots states and valance band can still contribute greatly to the photocurrent via both one-photon absorption process (1PA) and two-photon absorption process (2PA). The tailing states function as both the energy states for low energy photon absorption and the photocarriers extraction pathway. One of the biggest advantages of our method is that it can clearly differentiate the photocurrent due to 1PA process and 2PA process. Both 1PA and 2PA photocurrent generation efficiency in an InAs/GaAs QD device with photon excitation at 1550 nm have been quantitatively evaluated.

To Stand in Playful Gardens: the Statues of Roman Garden Paintings and Foucault’s Heterotopia
Creators: name: Lime, Emily Katherine
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2020

description: In this study, I examine the presence of painted representations of statuary in Roman garden paintings, through the lens of Michel Foucault’s concept of heterotopia. Previous scholarship concerning painted representations of statuary in wall painting has primarily focused on interior architectural schemes, with the monochromatic statues populating garden paintings viewed as outliers, due to their perceived failure to adhere to more general trends in painted statuary. I broadly examine this phenomenon of illusionistic representations of statuary in Roman wall painting, with specific attention to the use of color and the significance of statuary within the painted wall scheme. With this in mind, I then apply Foucault’s principles of heterotopia to Pompeian garden paintings in a series of case studies, as a means of examining the role of statues in the construction of garden space—both physically and conceptually. Through an application of Foucault’s idea of heterotopia, I consider how garden paintings and particularly their statuary elements reinforced the liminal nature of garden space through a series of temporal and spatial juxtapositions.

description: We consider a supersymmetric Wilson loop operator for 4d N=4 super Yang-Mills theory which is the natural object dual to the AdS_5 x S^5 superstring in the AdS/CFT correspondence. It generalizes the traditional bosonic 1/2 BPS Maldacena-Wilson loop operator and completes recent constructions in the literature to smooth (non-light-like) loops in the full N=4 non-chiral superspace. This Wilson loop operator enjoys global superconformal and local kappa-symmetry of which a detailed discussion is given. Moreover, the finiteness of its vacuum expectation value is proven at leading order in perturbation theory. We determine the leading vacuum expectation value for general paths both at the component field level up to quartic order in anti-commuting coordinates and in the full non-chiral superspace in suitable gauges. Finally, we discuss loops built from quadric splines joined in such a way that the path derivatives are continuous at the intersection.

description: Lying at the heart of quantum mechanics, coherence has recently been studied as a key resource in quantum information theory. Quantum steering, a fundamental notion originally considered by Schr{ö}dinger, has also recently received much attention. When Alice and Bob share a correlated quantum system, Alice can perform a local measurement to `steer' Bob's reduced state. We introduce the maximal steered coherence as a measure describing the extent to which steering can remotely create coherence; more precisely, we find the maximal coherence of Bob's steered state in the eigenbasis of his original reduced state, where maximization is performed over all positive-operator valued measurements for Alice. We prove that maximal steered coherence vanishes for quantum-classical states whilst reaching a maximum for pure entangled states with full Schmidt rank. Although invariant under local unitary operations, maximal steered coherence may be increased when Bob performs a channel. For a two-qubit state we find that Bob's channel can increase maximal steered coherence if and only if it is neither unital nor semi-classical, which coincides with the condition for increasing discord. Our results show that the power of steering for coherence generation, though related to discord, is distinct from existing measures of quantum correlation.

description: Most insects harbor influential, yet non-essential heritable microbes in their hemocoel. Communities of these symbionts exhibit low diversity. But their frequent multi-species nature raises intriguing questions on roles for symbiont-symbiont synergies in host adaptation, and on the stability of the symbiont communities, themselves. In this study, we build on knowledge of species-defined symbiont community structure across United States populations of the pea aphid, Acyrthosiphon pisum. Through extensive symbiont genotyping, we show that pea aphids' microbiomes can be more precisely defined at the symbiont strain level, with strain variability shaping ~5 out of 9 previously reported co-infection trends. Field data provide a mixture of evidence for symbiont-symbiont synergies, and symbiont hitchhiking, revealing causes and consequences of these co-infection trends. To test whether within-host metabolic interactions predict common versus rare strain-defined communities, we leveraged the high relatedness of our dominant, community-defined symbiont strains vs. twelve pea aphid-derived Gammaproteobacteria with sequenced genomes. Genomic inference, using metabolic complementarity indices, revealed high potential for cooperation among one pair of symbionts – Serratia symbiotica and Rickettsiella viridis. Applying the expansion network algorithm, through additional use of pea aphid and obligate Buchnera symbiont genomes, Serratia and Rickettsiella emerged as the only symbiont community requiring both parties to expand holobiont metabolism. Through their joint expansion of the biotin biosynthesis pathway, these symbionts may span missing gaps within a multi-party mutualism, within their nutrient-limited phloem-feeding hosts. Recent, complementary gene inactivation, within the biotin pathways of Serratia and Rickettsiella, raise further questions on the origins of mutualisms and host-symbiont interdependencies.

description: When investigating the mechanical behavior of fiber-reinforced polymers, fiber orientation plays a decisive role concerning anisotropy. Fiber orientation distributions are typically measured in the form of fiber orientation tensors. In order to measure orientation tensors, computed tomography scans and consecutive image processing methods have become one of the leading non-destructive testing methods. The conflict between scan resolution and sample size limits the volume that can be scanned. To obtain the fiber orientation behavior across an entire plate, a direct interpolation of orientation tensors computed from CT scans of smaller volumes at selected coordinates of the plate is implemented. Rather than a component-based interpolation, the authors chose a decomposition and reassembly method interpolating shape and orientation of the tensors separately. While this approach has been implemented and used for e.g. diffusion tensors in medical imaging, the authors consider the application to sparse but measured CT-based data to be a novelty.
Atmospheric Chemistry for Astrophysicists: A Self-consistent Formalism and Analytical Solutions for Arbitrary C/O

description: We present a self-consistent formalism for computing and understanding the atmospheric chemistry of exoplanets from the viewpoint of an astrophysicist. Starting from the first law of thermodynamics, we demonstrate that the van't Hoff equation (which describes the equilibrium constant), Arrhenius equation (which describes the rate coefficients) and procedures associated with the Gibbs free energy (minimisation, rescaling) have a common physical and mathematical origin. We address an ambiguity associated with the equilibrium constant, which is used to relate the forward and reverse rate coefficients, and restate its two definitions. By necessity, one of the equilibrium constants must be dimensionless and equate to an exponential function involving the Gibbs free energy, while the other is a ratio of rate coefficients and must therefore possess physical units. We demonstrate that the Arrhenius equation takes on a functional form that is more general than previously stated without recourse to tagging on ad hoc functional forms. Finally, we derive analytical models of chemical systems, in equilibrium, with carbon, hydrogen and oxygen. We include acetylene and are able to reproduce several key trends, versus temperature and carbon-to-oxygen ratio, published in the literature. The rich variety of behavior that mixing ratios exhibit as a function of the carbon-to-oxygen ratio is merely the outcome of stoichiometric book-keeping and not the direct consequence of temperature or pressure variations.

description: In this paper we consider the training of single hidden layer neural networks by pseudoinversion, which, in spite of its popularity, is sometimes affected by numerical instability issues. Regularization is known to be effective in such cases, so that we introduce, in the framework of Tikhonov regularization, a matricial reformulation of the problem which allows us to use the condition number as a diagnostic tool for identification of instability. By imposing well-conditioning requirements on the relevant matrices, our theoretical analysis allows the identification of an optimal value for the regularization parameter from the standpoint of stability. We compare with the value derived by cross-validation for overfitting control and optimisation of the generalization performance. We test our method for both regression and classification tasks. The proposed method is quite effective in terms of predictivity, often with some improvement on performance with respect to the reference cases considered. This approach, due to analytical determination of the regularization parameter, dramatically reduces the computational load required by many other techniques.

description: The aim of this retrospective study is to assess clinical outcomes of teeth via the periapical index (PAI) system to grade healing of periradicular tissues after long-term (30+ days) use of calcium hydroxide. 242 cases diagnosed with pulpal necrosis and apical periodontitis were treated with long-term calcium hydroxide under a standardized protocol. All cases were re-evaluated between one and three months until radiographic healing was observed. Clinical and radiographic evaluations were performed annually. Pre- and post-operative periapical radiographs were evaluated using the periapical index (PAI) system. Of the 242 cases, 219 participants completed their treatment with annual follow-up. The average calcium hydroxide time was 5.4 months. Overall, by the latest follow-up visit, 90.0% (197/219) were classified as "healed" and 10.0% (22/219) were classified as "diseased”. Within the limitations of this study, Calcium hydroxide is a suitable material of choice as an inter-appointment dressing for teeth diagnosed with pulpal necrosis and apical periodontitis.
Heat transport in the quantum Rabi model: Universality and ultrastrong coupling effects

description: Heat transport in the quantum Rabi model at weak interaction with the heat baths is controlled by the qubit-oscillator coupling. Universality of the linear conductance versus the temperature is found for $T\lesssim T_K$, with $T_K$ a coupling-dependent Kondo-like temperature. At low temperature, coherent heat transfer via virtual processes yields a $\sim T^3$ behavior with destructive interference in the presence of quasi-degeneracies in the spectrum. As the temperature increases, incoherent emission and absorption dominate and a maximum is reached at $T\sim T_K/2$. In the presence of a bias on the qubit, the conductance makes a transition from a resonant to a broad, zero-bias peak regime. Parallels and differences are found compared to the spin-boson model in [K. Saito and T. Kato, Phys. Rev. Lett. \textbf{111}, 214301 (2013)], where the qubit-bath coupling instead of the internal qubit-oscillator coupling rules thermal transport.
