description: Heterogenous cellular networks (HCN) introduce small cells within the transmission range of a macrocell. For the efficient operation of HCNs it is essential that the high power macrocell shuts off its transmissions for an appropriate amount of time in order for the low power small cells to transmit. This is a mechanism that allows time-domain resource partitioning (TDRP) and is critical to be optimized for maximizing the throughput of the complete HCN. In this paper, we investigate video communication in HCNs when TDRP is employed. After defining a detailed system model for video streaming in such a HCN, we consider the problem of maximizing the experienced video quality at all the users, by jointly optimizing the TDRP for the HCN, the rate allocated to each specific user, and the selected video quality transmitted to a user. The NP-hard problem is solved with a primal-dual approximation algorithm that decomposes the problem into simpler subproblems, making them amenable to fast well-known solution algorithms. Consequently, the calculated solution can be enforced in the time scale of real-life video streaming sessions. This last observation motivates the enhancement of the proposed framework to support video delivery with dynamic adaptive streaming over HTTP (DASH). Our extensive simulation results demonstrate clearly the need for our holistic approach for improving the video quality and playback performance of the video streaming users in HCNs.

description: Although gauge invariance is a postulate in fundamental theories of nature such as quantum electrodynamics, in quantum-simulation implementations of gauge theories it is compromised by experimental imperfections. In a recent work [Halimeh and Hauke, \href{https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.125.030503}{Phys. Rev. Lett. \textbf{125}, 030503 (2020)}], it has been shown in finite-size spin-$1/2$ quantum link lattice gauge theories that upon introducing an energy-penalty term of sufficiently large strength $V$, unitary gauge-breaking errors at strength $λ$ are suppressed $\proptoλ^2/V^2$ up to all accessible evolution times. Here, we show numerically that this result extends to quantum link models in the thermodynamic limit and with larger spin-$S$. As we show analytically, the dynamics at short times is described by an \textit{adjusted} gauge theory up to a timescale that is at earliest $τ_\text{adj}\propto\sqrt{V/V_0^3}$, with $V_0$ an energy factor. Moreover, our analytics predicts that a renormalized gauge theory dominates at intermediate times up to a timescale $τ_\text{ren}\propto\exp(V/V_0)/V_0$. In both emergent gauge theories, $V$ is volume-independent and scales at worst $\sim S^2$. Furthermore, we numerically demonstrate that robust gauge invariance is also retained through a single-body gauge-protection term, which is experimentally straightforward to implement in ultracold-atom setups and NISQ devices.

description: The promise constraint satisfaction problem (PCSP) is a recently introduced vast generalisation of the constraint satisfaction problem (CSP) that captures approximability of satisfiable instances. A PCSP instance comes with two forms of each constraint: a strict one and a weak one. Given the promise that a solution exists using the strict constraints, the task is to find a solution using the weak constraints. While there are by now several dichotomy results for fragments of PCSPs, they all consider (in some way) symmetric PCSPs. 1-in-3-SAT and Not-All-Equal-3-SAT are classic examples of Boolean symmetric (non-promise) CSPs. While both problems are NP-hard, Brakensiek and Guruswami showed [SICOMP'21] that given a satisfiable instance of 1-in-3-SAT one can find a solution to the corresponding instance of (weaker) Not-All-Equal-3-SAT. In other words, the PCSP template (1-in-3,NAE) is tractable. We focus on non-symmetric PCSPs. In particular, we study PCSP templates obtained from the Boolean template (t-in-k,NAE) by either adding tuples to t-in-k or removing tuples from NAE. For the former, we classify all templates as either tractable or not solvable by the currently strongest known algorithm for PCSPs, the combined basic LP and affine IP relaxation of Brakensiek, Guruswami, Wrochna, and Živný [SICOMP'20]. For the latter, we classify all templates as either tractable or NP-hard.

description: For any real number $s$, let $σ_s$ be the generalized divisor function, i.e., the arithmetic function defined by $σ_s(n) := \sum_{d \, \mid \, n} d^s$, for all positive integers $n$. We prove that for any $r > 1$ the topological closure of $σ_{-r}(\mathbf{N}^+)$ is the union of a finite number of pairwise disjoint closed intervals $I_1, \ldots, I_\ell$. Moreover, for $k=1,\ldots,\ell$, we show that the set of positive integers $n$ such that $σ_{-r}(n) \in I_k$ has a positive rational asymptotic density $d_k$. In fact, we provide a method to give exact closed form expressions for $I_1, \ldots, I_\ell$ and $d_1, \ldots, d_\ell$, assuming to know $r$ with sufficient precision. As an example, we show that for $r = 2$ it results $\ell = 3$, $I_1 = [1, π^2/9]$, $I_2 = [10/9, π^2/8]$, $I_3 = [5/4, π^2 / 6]$, $d_1 = 1/3$, $d_2 = 1/6$, and $d_3 = 1/2$.

description: This study explores the Gaussian and the Lorentzian distributed spherically symmetric wormhole solutions in the $f(τ, T)$ gravity. The basic idea of the Gaussian and Lorentzian noncommutative geometries emerges as the physically acceptable and substantial notion in quantum physics. This idea of the noncommutative geometries with both the Gaussian and Lorentzian distributions becomes more striking when wormhole geometries in the modified theories of gravity are discussed. Here we consider a linear model within $f(τ,T)$ gravity to investigate traversable wormholes. In particular, we discuss the possible cases for the wormhole geometries using the Gaussian and the Lorentzian noncommutative distributions to obtain the exact shape function for them. By incorporating the particular values of the unknown parameters involved, we discuss different properties of the new wormhole geometries explored here. It is noted that the involved matter violates the weak energy condition for both the cases of the noncommutative geometries, whereas there is a possibility for a physically viable wormhole solution. By analyzing the equilibrium condition, it is found that the acquired solutions are stable. Furthermore, we provide the embedded diagrams for wormhole structures under Gaussian and Lorentzian noncommutative frameworks. Moreover, we present the critical analysis on an anisotropic pressure under the Gaussian and the Lorentzian distributions.

description: OBJECTIVES: - To develop evidence-based guideline recommendations through a systematic review of the literature to establish standard molecular biomarker testing of colorectal cancer (CRC) tissues to guide epidermal growth factor receptor (EGFR) therapies and conventional chemotherapy regimens.

METHODS: - The American Society for Clinical Pathology, College of American Pathologists, Association for Molecular Pathology, and American Society of Clinical Oncology convened an expert panel to develop an evidence-based guideline to establish standard molecular biomarker testing and guide therapies for patients with CRC. A comprehensive literature search that included more than 4,000 articles was conducted.

RESULTS: - Twenty-one guideline statements were established.

CONCLUSIONS: - Evidence supports mutational testing for EGFR signaling pathway genes, since they provide clinically actionable information as negative predictors of benefit to anti-EGFR monoclonal antibody therapies for targeted therapy of CRC. Mutations in several of the biomarkers have clear prognostic value. Laboratory approaches to operationalize CRC molecular testing are presented.

description: Background: Nuclear fission is a complex large-amplitude collective decay mode in heavy nuclei. Microscopic density functional studies of fission have previously concentrated on adiabatic approaches based on constrained static calculations ignoring dynamical excitations of the fissioning nucleus, and the daughter products. Purpose: To explore the ability of dynamic mean-field methods to describe induced fission processes, using quadrupole boosts in the nuclide $^{240}$Pu as an example. Methods: Quadrupole constrained Hartree-Fock calculations are used to create a potential energy surface. An isomeric state and a state beyond the second barrier peak are excited by means of instantaneous as well as temporally extended gauge boosts with quadrupole shapes. The subsequent deexcitation is studied in a time-dependent Hartree-Fock simulation, with emphasis on fissioned final states. The corresponding fission fragment mass numbers are studied. Results: In general, the energy deposited by the quadrupole boost is quickly absorbed by the nucleus. In instantaneous boosts, this leads to fast shape rearrangements and violent dynamics that can ultimately lead to fission. This is a qualitatively different process than the deformation-induced fission. Boosts induced within a finite time window excite the system in a relatively gentler way, and do induce fission but with a smaller energy deposition. Conclusions: The fission products obtained using boost-induced fission in time-dependent Hartree-Fock are more asymmetric than the fragments obtained in deformation-induced fission, or the corresponding adiabatic approaches.

description: The relationship between urban mobility, social networks and socioeconomic status is complex and difficult to apprehend, notably due to the lack of data. Here we use mobile phone data to analyze the socioeconomic structure of spatial and social interaction in the Chilean's urban system. Based on the concept of spatial and social events, we develop a methodology to assess the level of spatial and social interactions between locations according to their socioeconomic status. We demonstrate that people with the same socioeconomic status preferentially interact with locations and people with a similar socioeconomic status. We also show that this proximity varies similarly for both spatial and social interactions during the course of the week. Finally, we highlight that these preferential interactions appear to be holding when considering city-city interactions.

description: AbstractObjectiveTo determine whether severity of head and extracranial injuries (ECI) is associated with suicidal ideation (SI) or suicide attempt (SA) after traumatic brain injury (TBI).DesignFactors associated with SI and SA were assessed in this inception cohort study using data collected 1, 2, and 5 years post-TBI from the National Trauma Data Bank and Traumatic Brain Injury Model Systems (TBIMS) databases.SettingLevel I trauma centers, inpatient rehabilitation centers, and the community.ParticipantsParticipants with TBI from 15 TBIMS Centers with linked National Trauma Data Bank trauma data (N=3575).InterventionsNot applicable.Main Outcome MeasuresSI was measured via the Patient Health Questionnaire 9 (question 9). SA in the last year was assessed via interview. ECI was measured by the Injury Severity Scale (nonhead) and categorized as none, mild, moderate, or severe.ResultsThere were 293 (8.2%) participants who had SI without SA and 109 (3.0%) who had SA at least once in the first 5 years postinjury. Random effects logit modeling showed a higher likelihood of SI when ECI was severe (odds ratio=2.73; 95% confidence interval, 1.55–4.82; P=.001). Drug use at time of injury was also associated with SI (odds ratio=1.69; 95% confidence interval, 1.11–2.86; P=.015). Severity of ECI was not associated with SA.ConclusionsSevere ECI carried a nearly 3-fold increase in the odds of SI after TBI, but it was not related to SA. Head injury severity and less severe ECI were not associated with SI or SA. These findings warrant additional work to identify factors associated with severe ECI that make individuals more susceptible to SI after TBI.
title: What happens to whiteness upon migration? An examination of the dual transnationalism of White Zimnabwean emigrants
Creators: name: Middernacht, Zdena Khangezile
Publisher: name: University of Kent
Year: 2023

description: This thesis examines the development of dual transnationalism and diasporism among white Zimbabweans, arguing that they are dual transnationals following their – or their families’ - migration to Zimbabwe and their own subsequent emigration elsewhere. Whiteness both complicates and facilitates their movement, and their whiteness, in turn, is affected by their dual transnationalism. This thesis examines these interactions, ultimately examining what happens to whiteness upon migration. ‘Whiteness’ in this thesis is conceptualised as the interplay between power, privilege and identity, whose production and reproduction is historical, contextual, multi-layered and perpetually shifting. The thesis challenges the notion of whiteness as invisible, showing how migration experiences redefine power, privilege and identity to create relativity within whiteness. For white Zimbabwean emigrants, this leads to a subjective visibility of whiteness. The analysis demonstrates how colonial and post-colonial power structures shape individuals’ conceptualisations of their white identity as Euro-centric. Upon emigration from Zimbabwe, those same power structures provoke experiences that position individuals on the periphery of whiteness. This leads to a reconceptualisation of individual identities and the notion of ‘home’ so that white Zimbabweans re-conceptualise themselves as Afro-centric and embrace their hybridity. Thus, the thesis contributes to an understanding of positions of duality, specifically, white Zimbabwean experiences of dual diasporism and dual transnationalism. It draws on a translocational lens on intersectionality; transnationalism, intersectionality and whiteness literature. The research draws on 23 narrative and in-depth interviews with white Zimbabwean emigrants.

description: Diskoseismology, the theoretical study of normal mode oscillations in geometrically thin, optically thick accretion disks, is a strong candidate to explain some QPOs in the power spectra of many black hole X-ray binary systems. The existence of g-modes, presumably the most robust and visible of the modes, depends on general relativistic gravitational trapping in the hottest part of the disk. As the existence of the required cavity in the presence of magnetic fields has been put into doubt by theoretical calculations, we will explore in greater generality what the inclusion of magnetic fields has to say on the existence of g-modes. We use an analytical perturbative approach on the equations of MHD to assess the impact of such effects. Our main conclusion is that there appears to be no compelling reason to discard g-modes. In particular, the inclusion of a non-zero {\it radial} component of the magnetic field enables a broader scenario for cavity non-destruction, especially taking into account recent simulations' saturation values for the magnetic field.

This dependence is a simple linear one, when expressed in terms of appropriate variables, suggesting an exact mathematical law. This is the first known relation between topological and kinematical properties of three-body systems. We have used these results to predict the periods of several sets of as yet undiscovered orbits, but the relation also indicates that the number of periodic three-body orbits with periods shorter than any finite number is countable.

description: The present study compared the prevalence and variation in high-risk sexual behaviors among four monoracial (i.e., White, African American, Asian, Native American) and four multiracial (i.e., White/African American, White/Asian, White/Native American, African American/Native American) young adults using Wave IV data (2008–2009) from the National Longitudinal Study of Adolescent to Adult Health (N = 9724). Findings indicated differences in the sexual behavior of monoracial and multiracial young adults, but directions of differences varied depending on the monoracial group used as the referent and gender. Among males, White/African Americans had higher risk than Whites; White/Native Americans had higher risk than Native Americans. Otherwise, multiracial groups had lower risk or did not differ from the single-race groups. Among females, White/Native Americans had higher risk than Whites; White/African Americans had higher risk than African Americans. Other comparisons showed no differences or had lower risk among multiracial groups. Variations in high-risk sexual behaviors underscore the need for health research to disaggregate multiracial groups to better understand health behaviors and outcomes in the context of experiences associated with a multiracial background, and to improve prevention strategies.

description: Near-term quantum computers provide a promising platform for finding ground states of quantum systems, which is an essential task in physics, chemistry, and materials science. Near-term approaches, however, are constrained by the effects of noise as well as the limited resources of near-term quantum hardware. We introduce "neural error mitigation," which uses neural networks to improve estimates of ground states and ground-state observables obtained using near-term quantum simulations. To demonstrate our method's broad applicability, we employ neural error mitigation to find the ground states of the H$_2$ and LiH molecular Hamiltonians, as well as the lattice Schwinger model, prepared via the variational quantum eigensolver (VQE). Our results show that neural error mitigation improves numerical and experimental VQE computations to yield low energy errors, high fidelities, and accurate estimations of more-complex observables like order parameters and entanglement entropy, without requiring additional quantum resources. Furthermore, neural error mitigation is agnostic with respect to the quantum state preparation algorithm used, the quantum hardware it is implemented on, and the particular noise channel affecting the experiment, contributing to its versatility as a tool for quantum simulation.

description: We analyze the interplay between charge-density-wave (CDW) orders with axial momenta $(Q, 0)$ and $(0,Q)$ ($Δ_x$ and $Δ_y$ respectively), detected in the underdoped cuprates. The CDW order in real space can be uni-directional (either $Δ_x$ or $Δ_y$ is non-zero) or bi-directional (both $Δ_x$ and $Δ_y$ are non-zero). To understand which of the two orders develop, we adopt the magnetic scenario, in which the CDW order appears due to spin-fluctuation exchange, and derive the Ginzburg-Landau action to the sixth order in $Δ_x$ and $Δ_y$. We argue that, at the mean-field level, the CDW order is bi-directional at the onset, with equal amplitudes of $Δ_x$ and $Δ_y$, but changes to uni-directional inside the CDW phase. This implies that, at a given temperature, CDW order is uni-directional at smaller dopings, but becomes bi-directional at larger dopings. This is consistent with recent x-ray data on YBCO, which detected tendency towards bi-directional order at larger dopings. We discuss the role of discrete symmetry breaking at a higher temperature for the interplay between bi-directional and uni-directional CDW orders and also discuss the role of pair-density-wave (PDW) order, which may appear along with CDW. We argue that PDW with the same momentum as CDW changes the structure of the bi-directional charge order by completely replacing either $Δ_x$ or $Δ_y$ CDW components by PDW. However, if an "Amperean" PDW order, which pairs fermions with approximately the same momenta, is also present, both $Δ_x$ and $Δ_y$ remain non-zero in the bi-directional phase, albeit with non-equal amplitudes. This is again consistent with x-ray experiments, which at larger doping found non-equal $Δ_x$ and $Δ_y$ in every domain.

description: We extend a machine learning (ML) framework presented previously to model galaxy formation and evolution in a hierarchical universe using N-body + hydrodynamical simulations. In this work, we show that ML is a promising technique to study galaxy formation in the backdrop of a hydrodynamical simulation. We use the Illustris Simulation to train and test various sophisticated machine learning algorithms. By using only essential dark matter halo physical properties and no merger history, our model predicts the gas mass, stellar mass, black hole mass, star formation rate, $g-r$ color, and stellar metallicity fairly robustly. Our results provide a unique and powerful phenomenological framework to explore the galaxy-halo connection that is built upon a solid hydrodynamical simulation. The promising reproduction of the listed galaxy properties demonstrably place ML as a promising and a significantly more computationally efficient tool to study small-scale structure formation. We find that ML mimics a full-blown hydrodynamical simulation surprisingly well in a computation time of mere minutes. The population of galaxies simulated by ML, while not numerically identical to Illustris, is statistically and physically robust and follows the same fundamental observational constraints. Machine learning offers an intriguing and promising technique to create quick mock galaxy catalogs in the future.

description: Trianthema sedifolia Visiani (1836a: 203; also treated in Visiani 1836b: 19; 1836c: 66)
 Locus classicus: —“circa Chartum in Sennaar”.
 Lectotype (designated here):—Illustration in Visiani 1836a: tab. 3 fig. 1 (see Fig. 4).
 Additional specimen examined: — EGYPT. s.l., [1824–1826], Brocchi s.n. (PI005425!).
 Note:—The only available specimen we examined bears, in the handwriting of Visiani and with his signature, the indication “In Aegypto”, while the locus classicus mentions Khartoum, Nubia. It is possible that in this occasion Visiani used “ Egypt ” as a generic term to refer to the whole area, especially taking into account that Khartoum was indeed an Egyptian city at that time (see introduction). It was also certainly recognised by Visiani himself as pertaining to his T. sedifolia. Nevertheless, according to the identification key available in Hassan et al. (2005), the description in Hartmann et al. (2011), the protologue itself (Visiani 1836a), and as was confirmed by Aizoaceae expert Sigrid Liede-Schumann (pers. comm.), the said specimen certainly does not belong to T. sedifolia: the most striking inconsistencies being the size and shape of its leaves (2.5–3.0 × 1.5–2.1 mm, vs 5–12 × 0.5–2.0 mm in T. sedifolia) and the fact that it is completely covered in idioblasts, whereas they are sparse in T. sedifolia, in the sense that this taxon is now accepted by e.g. Hartmann et al. (2011) and other recent authors. We could only tentatively identify PI005425 as pertaining to Sesuvium sesuvioides (Fenzl) Verdcourt (1957). The only available specimen from the original material is therefore “in serious conflict with the protologue”, so that “an element that is not in conflict with the protologue is to be chosen” (see Art. 9.19, Turland et al. 2018). Given that the treatment in Hartmann et al. (2011) was based on the illustration accompanying Visiani (1836b), we consider it particularly suitable as a lectotype. Due to the challenges presented and the scant material available, any attempt at designating an epitype should be left to the specialists on this group of plants.

description: Building on techniques recently introduced by the second author, and further developed by the first author, we show that a positive integer $N$ may be rigorously and deterministically factored into primes in at most \[ O\left( \frac{N^{1/5} \log^{16/5} N}{(\log\log N)^{3/5}}\right) \] bit operations. This improves on the previous best known result by a factor of $(\log \log N)^{3/5}$.

description: Globally, suicidal ideation and behavior have been widely reported among people living with human immunodeficiency virus (HIV). Knowledge gaps exist regarding the longer life and resilience-related experiences of people living with HIV (PLWH). Specifically, there is a dearth of data about the interaction of perceived risk and resilient factors resulting in a wide spectrum of intentional suicidal ideation outcomes in a Chinese cultural context. This qualitative research drew from a larger ethnographic study of newly diagnosed HIV-positive men who have sex with men (MSM) in Mainland China. Interviews were conducted with 31 MSM within 6 months of diagnosis of HIV infection. Initial suicidal ideation was commonly reported with participants subsequently feeling more resilient to these thoughts through gaining a greater understanding of their prognosis and treatment. Post-HIV diagnosis, some participants reported forming new relationships and receiving increased support from their partners, friends, peers, families, and community-based organizations. At follow-up, these participants generally reported suicidal ideation had declined. However, participants who continued to express suicidal ideation perceived extended pressure from their families’ expectations for them to engage in heterosexual marriages and parenthood. Furthermore, these men reported ongoing hardships in their daily life, unemployment, lack of social support, and isolation. Among this Mainland Chinese cohort of HIV-positive MSM, suicidal ideation may be a transient phenomenon experienced initially following HIV diagnosis that resolves with increased and specific familial, social, and service-based support. It is crucial to identify the causes of stress and social suffering associated with HIV diagnosis in order to reduce suicidal ideation. In China, action is needed to develop routine mental health screening and to increase services that support PLWH. Important services mechanism to accomplish this are promoting resilience through intentional activities as well as continued public health campaigns to reduce stigma toward HIV-positive MSM.
A Simple Optimal Contention Resolution Scheme for Uniform Matroids

description: Contention resolution schemes (or CR schemes), introduced by Chekuri, Vondrak and Zenklusen, are a class of randomized rounding algorithms for converting a fractional solution to a relaxation for a down-closed constraint family into an integer solution. A CR scheme takes a fractional point $x$ in a relaxation polytope, rounds each coordinate $x_i$ independently to get a possibly non-feasible set, and then drops some elements in order to satisfy the constraints. Intuitively, a contention resolution scheme is $c$-balanced if every element $i$ is selected with probability at least $c \cdot x_i$. It is known that general matroids admit a $(1-1/e)$-balanced CR scheme, and that this is (asymptotically) optimal. This is in particular true for the special case of uniform matroids of rank one. In this work, we provide a simple and explicit monotone CR scheme for uniform matroids of rank $k$ on $n$ elements with a balancedness of $1 - \binom{n}{k}\:\left(1-\frac{k}{n}\right)^{n+1-k}\:\left(\frac{k}{n}\right)^k$, and show that this is optimal. As $n$ grows, this expression converges from above to $1 - e^{-k}k^k/k!$. While this asymptotic bound can be obtained by combining previously known results, these require defining an exponential-sized linear program, as well as using random sampling and the ellipsoid algorithm. Our procedure, on the other hand, has the advantage of being simple and explicit. This scheme extends naturally into an optimal CR scheme for partition matroids.
