description: The utilization of millimeter-wave (mmWave) bands in 5G networks poses new challenges to network planning. Vulnerability to blockages at mmWave bands can cause coverage holes (CHs) in the radio environment, leading to radio link failure when a user enters these CHs. Detection of the CHs carries critical importance so that necessary remedies can be introduced to improve coverage. In this letter, we propose a novel approach to identify the CHs in an unsupervised fashion using a state-of-the-art manifold learning technique: uniform manifold approximation and projection. The key idea is to preserve the local-connectedness structure inherent in the collected unlabelled channel samples, such that the CHs from the service area are detectable. Our results on the DeepMIMO dataset scenario demonstrate that the proposed method can learn the structure within the data samples and provide visual holes in the low-dimensional embedding while preserving the CH boundaries. Once the CH boundary is determined in the low-dimensional embedding, channel-based localization techniques can be applied to these samples to obtain the geographical boundaries of the CHs.

description: The last multiplier of Jacobi provides a route for the determination of families of Lagrangians for a given system. We show that the members of a family are equivalent in that they differ by a total time derivative. We derive the Schrödinger equation for a one-degree-of-freedom system with a constant multiplier. In the sequel we consider the particular example of the simple harmonic oscillator. In the case of the general equation for the simple harmonic oscillator which contains an arbitrary function we show that all Schrödinger equations possess the same number of Lie point symmetries with the same algebra. From the symmetries we construct the solutions of the Schrödinger equation and find that they differ only by a phase determined by the gauge.

Agriculture and energy transmission facilities
Creators: name: Goldstein, Michael Jacob
Publisher: name: University of British Columbia

description: This thesis is concerned with direct interactions between energy transmission facilities and agricultural operations. The objective of this study is to determine to what extent government regulation is advisable where energy transmission facilities occupy agricultural land. The area of electrical transmission line and pipeline rights-of-way within the Agricultural Land Reserve of British Columbia was found to be approximately 174 km² or about 0.37% of the Reserve. Impacts to farmers were found to vary with the type of agricultural practices and the type of energy transmission facility. On intensively farmed land, electrical transmission lines could increase the cost of irrigation by as much as $1,000 per year, per kilometre of line. Land loss due to transmission line towers was found to reach 345 m² per kilometre of transmission line. A wide variety of other impacts were also found. In grazing areas, impacts to agriculture were generally positive. The clearing of electrical transmission lines could increase grazing capacities by 10.4 animal unit months per year per kilometre of right-of-way. Pipelines were found to have less impacts on agriculture than electrical lines. The most serious impact was yield loss along trenchlines on fine textured soils. The maximum value of such losses was $500 per kilometre of pipeline. The cost of energy transmission facilities avoiding farmland was found to vary greatly with terrain and location. In many situations this cost can exceed $100,000 per kilometre of right-of-way, which is significantly higher than the value of any impact they can have on agtriculture. Federal and Provincial regulation of energy transmission facilities requires the compensation of affected persons and the reduction of negative impacts. Deficiencies in both processes were found. New Federal Legislation will increase the protection of affected persons, but unclear jurisdiction and problems of accurately assessing impacts will persist. Provincial regulation is more discretionary but has been well implemented in some cases. The conclusion reached by the author is that transmission operators can and should bear the cost of all impacts on agriculture, and that the only way of consistently relieving this cost over the long term is to require compensation in kind.

description: In free electron laser facilities, almost every kind of device will generate wakefield when an electron beam passes through it. Most of the wakefields are undesired and have a negative effect on the electron beam, which means a decrease of FEL performance. As for the SXFEL test facility, the sophisticated layout and the cumulative effect of such a long undulator section lead to an obvious wakefield, which is strong enough that can not be ignored. Based on two deflecting cavities at the entrance and the exit of the undulator section with corresponding profile monitors, we measured the wakefield of the undulator section. In this paper, we give the theoretical and simulation results of resistive wall wakefields which agree well with each other. In addition, the experimental and the simulation results of the overall undulator wakefield are given showing small difference. In order to explore the impact of this wakefield on FEL lasing, we give the simulation results of FEL with and without wakefield for comparison. There is almost no impact on 44 nm FEL in stage-1 of cascaded EEHG-HGHG mode, while the impact on 8.8 nm FEL in stage-2 becomes critical decreasing the pulse energy and peak power by 42% and 27% and broadening the bandwidth.

description: We study the key features of the Josephson transport through a curved semiconducting nanowire. Based on numerical simulations and analytical estimates within the framework of the Bogoliubov-de Gennes equations we find the ground-state phase difference $φ_0$ between the superconducting leads tuned by the spin splitting field $h$ driving the system from the topologically trivial to the nontrivial superconducting state. The phase $φ_0$ vanishes for rather small $h$, grows in a certain field range around the topological transition, and then saturates at large $h$ in the Kitaev regime. Both the subgap and the continuum quasiparticle levels are responsible for the above behavior of the anomalous Josephson phase. It is demonstrated that the crossover region on $φ_0(h)$ dependencies reveals itself in the superconducting diode effect. The resulting tunable phase battery can be used as a probe of topological transitions in Majorana networks and can become a useful element of various quantum computation devices.

description: A microscopic model for three-cluster configurations in light nuclei is presented. It uses an expansion in terms of Faddeev components for which the dynamic eqations are derived. The model is designed to investigate binary channel processes in a compound system. Gaussian and oscillator bases are used to expand the wave function and to represent appropriate boundary conditions. We study the effect of cluster polarization on ground and resonance states of 7Be, and on the astrophysical S-factor of the reaction 6Li(p,3He)4He.

description: We fit the recently published Pierre Auger ultra-high energy cosmic ray spectrum assuming that either nucleons or nuclei are emitted at the sources. We consider the simplified cases of pure proton, or pure oxygen, or pure iron injection. We perform an exhaustive scan in the source evolution factor, the spectral index, the maximum energy of the source spectrum Z E_{max}, and the minimum distance to the sources. We show that the Pierre Auger spectrum agrees with any of the source compositions we assumed. For iron, in particular, there are two distinct solutions with high and low E_{max} (e.g. 6.4 10^{20} eV and 2 10^{19} eV) respectively which could be distinguished by either a large fraction or the near absence of proton primaries at the highest energies. We raise the possibility that an iron dominated injected flux may be in line with the latest composition measurement from the Pierre Auger Observatory where a hint of heavy element dominance is seen.

description: included 24-hour food recalls, infant feeding practices, women's food preferences and frequency of food intake. Anthropometry consisted of weight, height, mid-upper-arm circumference (MUAC), and triceps skinfold (TSF) thickness measurements in women and children, with additional head circumference measurements in children less than 3 years. Major findings from dietary assessment revealed that adult diets were simplistic, consisting primarily of rice, beans, and coffee (with sugar). Analysis of nutrient intake and comparison with international standards showed that women were probably at high risk for vitamin A, iron, calcium, ascorbic acid, and riboflavin deficiencies; children appeared at high risk for vitamin A, iron, and ascorbic acid deficiencies. Infant feeding practices indicated that all children (under 5 years) had been breast fed at birth, although many were weaned at an early age. Negative nutritional infant feeding practices were reported, especially for conditions such as fever and diarrhoea. Belief in the "hot/cold" food classification system was reported by women. Although food taboos were reported for menstruation, pregnancy, immediately post partum, and lactation, relatively few taboos had potentially negative nutritional consequences. Anthropometric assessment indicated that a significant number of women were probably undernourished; a small percentage of women, however, were overweight or obese. Children did not generally appear undernourished; many, however, were stunted in growth. Summative evaluation of the nutrition education program indicated that for women who participated in the program, nutrition knowledge scores showed improvement and were statistically significant at ∝ =.05, using Wilcoxon signed rank test.

description: The quantum states built with the eta paring mechanism i.e., eta pairing states, were first introduced in the context of high temperature superconductivity where they were recognized as important example of states allowing for off-diagonal long-range order (ODLRO). In this paper we describe the structure of the correlations present in these states when considered in their momentum representation and we explore the relations between the quantum bipartite/multipartite correlations exhibited in k space and the direct lattice superconducting correlations. In particular, we show how the negativity between paired momentum modes is directly related to the ODLRO. Moreover, we investigate the dependence of the block entanglement on the choice of the modes forming the block and on the ODLRO; consequently we determine the multipartite content of the entanglement through the evaluation of the generalized "Meyer Wallach" measure in the direct and reciprocal lattice. The determination of the persistency of entanglement shows how the network of correlations depicted exhibits a self-similar structure which is robust with respect to "local" measurements. Finally, we recognize how a relation between the momentum-space quantum correlations and the ODLRO can be established even in the case of BCS states.

description: Warm dense matter (WDM) has emerged as one of the frontiers of both experimental and theoretical physics and is challenging traditional concepts of plasma, atomic, and condensed-matter physics. While it has become common practice to model correlated electrons in WDM within the framework of Kohn-Sham density functional theory, quantitative benchmarks of exchange-correlation (XC) functionals under WDM conditions are yet incomplete. Here, we present the first assessment of common XC functionals against exact path-integral Monte Carlo calculations of the harmonically perturbed thermal electron gas. This system is directly related to the numerical modeling of X-Ray scattering experiments on warm dense samples. Our assessment yields the parameter space where common XC functionals are applicable. More importantly, we pinpoint where the tested XC functionals fail when perturbations on the electronic structure are imposed. We indicate the lack of XC functionals that take into account the needs of WDM physics in terms of perturbed electronic structures.

description: Some time ago it was pointed out that the presence of cosmological components could affect the propagation of gravitational waves (GW) beyond the usual cosmological redshift and that such effects might be observable in pulsar timing arrays. These analyses were done at leading order in the Hubble constant $H_0$, which is proportional to $Λ^{1/2}$ and $ρ_i^{1/2}$ ($ρ_i$ being the various cosmological fluid densities). In this work, we study in detail the propagation of metric perturbations on a Schwarzschild-de Sitter (SdS) background, close to the place where GW are produced, and obtain solutions that incorporate corrections linear in $ρ_i$ and $Λ$. At the next-to-leading order the corrections do not appear in the form of $H_0$ thus lifting the degeneracy among the various cosmological components. We also determine the leading corrections proportional to the mass of the final object; they are very small for the distances considered in pulsar timing arrays but may be of relevance in other cases. When transformed into comoving coordinates, the ones used in cosmological measurements, this SdS solution does satisfy the perturbation equations in a Friedmann-Lemaître-Robertson-Walker metric up to and including $Λ^{3/2}$ terms. This analysis is then extended to the other cosmological fluids, allowing us to consider GW sources in the Gpc range. Finally, we investigate the influence of these corrections in pulsar timing arrays observations.

description: The semantics of emoji has, to date, been considered from a static perspective. We offer the first longitudinal study of how emoji semantics changes over time, applying techniques from computational linguistics to six years of Twitter data. We identify five patterns in emoji semantic development and find evidence that the less abstract an emoji is, the more likely it is to undergo semantic change. In addition, we analyse select emoji in more detail, examining the effect of seasonality and world events on emoji semantics. To aid future work on emoji and semantics, we make our data publicly available along with a web-based interface that anyone can use to explore semantic change in emoji.

description: Preheating can convert superhorizon fluctuations of light scalar fields present at the end of inflation into observable density perturbations. We show in detail how lattice field theory simulations and the separate universes approximation can be used to calculate these perturbations and make predictions for the nonlinearity parameter fNL . We also present a simple approximation scheme that can reproduce these results analytically. Applying these methods to the massless preheating model, we determine the parameter values that are ruled out by too high levels of non-Gaussianity.

description: Human-Robot Collaboration (HRC) has evolved into a highly promising issue owing to the latest breakthroughs in Artificial Intelligence (AI) and Human-Robot Interaction (HRI), among other reasons. This emerging growth increases the need to design multi-agent algorithms that can manage also human preferences. This paper presents an extension of the Ant Colony Optimization (ACO) meta-heuristic to solve the Minimum Time Search (MTS) task, in the case where humans and robots perform an object searching task together. The proposed model consists of two main blocks. The first one is a convolutional neural network (CNN) that provides the prior probabilities about where an object may be from a segmented image. The second one is the Sub-prior MTS-ACO algorithm (SP-MTS-ACO), which takes as inputs the prior probabilities and the particular search preferences of the agents in different sub-priors to generate search plans for all agents. The model has been tested in real experiments for the joint search of an object through a Vizanti web-based visualization in a tablet computer. The designed interface allows the communication between a human and our humanoid robot named IVO. The obtained results show an improvement in the search perception of the users without loss of efficiency.

description: Gegenstand dieses Beitrags ist die Integration der Geschlechterperspektive in die biomedizinische Forschung. Es wird der Frage nachgegangen, ob und inwieweit ein Geschlechterbewusstsein, das beiden Geschlechtern (männ lichen und weiblichen Individuen) gerecht wird, in den Fachorganisationen der biomedizinischen Forschung, in den Fachgesellschaften, Förderorganisationen und Fachzeitschriften verbreitet ist. Dadurch hat dieser Beitrag auch eine wissenschaftspolitische Bedeutung und Zielsetzung. Wir haben die Situation einer geschlechterdifferenzierenden biomedizinischen Forschung in Deutschland mithilfe einer anonymen Umfrage bei den relevanten Fachorganisationen analysiert. Diese Untersuchung ergab, dass Fachgesellschaften, Förderorganisationen und Fachzeitschriften die Integration der Geschlechterperspektive in die biomedizinische Forschung als wichtig erachten. In der Praxis planen sie jedoch weder gegenwärtig noch in Zukunft eine Änderung der Leitlinien für die Forschenden. Dementsprechend ergab eine Analyse von Veröffentlichungen des vom BMBF geförderten „Nationalen Bernstein Netzwerks Computational Neuroscience“, die sich mit neurowissenschaftlichen Studien am Menschen beschäftigten, dass keine geschlechterdifferenzierte Datenauswertung stattfand. Die Begutachtungsrichtlinien für Forschungsanträge und Publikationen der Förderorganisationen und Zeitschriften mit Sitz in Deutschland müssen daher verändert werden. Auf lange Sicht gesehen wird nur eine frühzeitige Integration von geschlechterdifferenzierten Forschungsbefunden in die grundständige Lehre der Medizin und Naturwissenschaften zu einem Umdenken bei den Forschenden führen.

description: The angular-dependent magnetoresistance (AMR) of the ab plane is measured on the single crystals of FeSe1-xSx (x = 0, 0.07, 0.13 and 1) and FeSe1-yTey (y = 0.06, 0.61 and 1) at various temperatures under fields up to 9 T. A pronounced twofold-anisotropic carrier-scattering effect is identified by AMR, and attributed to a magnetic-field-induced spin nematicity that emerges from the tetragonal normal-state regime below a characteristic temperature Tsn. This magnetically polarized spin nematicity is found to be ubiquitous in the isoelectronic FeSe1-xSx and FeSe1-yTey systems, no matter whether the sample shows an electronic nematic order at Ts < Tsn, or an antiferromagnetic order at TN < Tsn, or neither order. Importantly, we find that the isoelectronic substitution with sulfur does not suppress but even enhances the characteristic Tsn of the induced spin nematicity in FeSe1-xSx samples. This contrasts sharply with their rapidly suppressed Ts, the transition temperature of the spontaneous electronic nematicity. Furthermore, we find that the superconductivity is significantly suppressed with the enhancement of the induced spin nematicity in both FeSe1-xSx and FeSe1-yTey samples.

description: The physics of quantum degenerate Fermi gases in uniform as well as in harmonically trapped configurations is reviewed from a theoretical perspective. Emphasis is given to the effect of interactions which play a crucial role, bringing the gas into a superfluid phase at low temperature. In these dilute systems interactions are characterized by a single parameter, the s-wave scattering length, whose value can be tuned using an external magnetic field near a Feshbach resonance. The BCS limit of ordinary Fermi superfluidity, the Bose-Einstein condensation (BEC) of dimers and the unitary limit of large scattering length are important regimes exhibited by interacting Fermi gases. In particular the BEC and the unitary regimes are characterized by a high value of the superfluid critical temperature, of the order of the Fermi temperature. Different physical properties are discussed, including the density profiles and the energy of the ground-state configurations, the momentum distribution, the fraction of condensed pairs, collective oscillations and pair breaking effects, the expansion of the gas, the main thermodynamic properties, the behavior in the presence of optical lattices and the signatures of superfluidity, such as the existence of quantized vortices, the quenching of the moment of inertia and the consequences of spin polarization. Various theoretical approaches are considered, ranging from the mean-field description of the BCS-BEC crossover to non-perturbative methods based on quantum Monte Carlo techniques. A major goal of the review is to compare the theoretical predictions with the available experimental results.

description: We perform a measurement of the CP asymmetry in b->sgamma decays using a sample of 383 BB events collected by the BABAR detector at the PEP-II asymmetric B factory. We reconstruct sixteen flavor-specific B decay modes containing a high-energy photon and a hadronic system (Xs) containing an s quark. We measure the \CP asymmetry to be -0.011+/- 0.030(stat)+/-0.014(syst) for a photon energy threshold at 1.6 GeV and the hadronic system mass between 0.6 and 2.8 GeV/c2.

description: A scheme for controlling light speed from slower-than-c to faster-than-c in an atomic system is presented in this paper. The scheme is based on far detuning Raman effect. Two far detuning coupling fields with small frequency difference will produce two absorptive peaks for the probe field in a $Λ$ structure, and an optical pump between the two ground states can change the absorptive peaks into enhanced peaks, which makes the normal dispersion between the two peaks change into anomalous dispersion, so the probe field can change from slow light to superluminal propagation.

Tetranychus evansi

description: Tetranychus evansi Baker & Pritchard, 1960
 Male of T. evansi has a slender aedeagal shaft that curves dorsad; axis of knob forms a strong angle with shaft axis; knob very small but bearing a small anterior projection and a relatively longer acute and somewhat deflexed posterior projection (Figure 5 A). Female tarsus I with proximal pair of duplex setae more or less in a line with tactile setae and empodium I with a minute mediodorsal spur.
 Specimens examined: Many specimens have been examined all collected on solanaceous plants from Kenya which include Lycopersicon esculentum from Kajiado, Migori, Suba, Nakuru, Machakos, Kwale, Makueni and Taita districts; Solanum incanum from Mwea; Solanum nigrum from Baringo, Kiambu and Taita; Solanum melongena from Kibwezi and Machakos and Solanum tuberosum from Sagana, Nyeri district.
 Remarks: This species was first described from Mauritius on Lycopersicon esculentum (Baker and Pritchard, 1960) and is considered an invasive in Africa and parts of Europe. It has a worldwide occurrence but is not considered as a serious pest in the country of origin which is believed to be Brazil. However, in introduced places, it posses a threat to commercial production of solanaceous crops especially in greenhouse conditions and warmer climates. This species has been reported on a wide variety of host plants but it shows preference for plants from the family solanaceae. An earlier report of this species was on Lycopersicon esculentum (Solanaceae) from Kirinyaga district (Knapp et al., 2003) and is currently the most important pest in tomato production in Kenya being wide spread in the major tomato growing areas. Biological control of this pest using the phytoseiid mite Phytoseiulus longipes Evans are underway and preliminary results in Kenya show high levels of control in the laboratory. However, field efficacy of the predator is not known since field releases have not been carried out. This species is brick-red to dark orange in colour when observed in the field. It produces dense webbing compared to the other species of the same genus in the field. In severe cases, the web produced covers the entire plant. Some pesticides registered for the control of spider mite are still effective in their control except dimethoate which is ineffective against T. evansi (Toroitich, unpublished data).

Step-edge epitaxy for borophene growth on insulators

description: Borophene, a monoatomic layer of boron atoms, stands out among two-dimensional (2D) materials, with its versatile properties of polymorphism, metallicity, plasmonics, superconductivity, tantalizing for physics exploration and next-generation devices. Yet its phases are all synthesized on and stay bound to metal substrates, hampering both characterization and use. The growth on the inert insulator would allow post-synthesis exfoliation of borophene, but its weak adhesion to such substrate results in a very high 2D-nucleation barrier preventing clean borophene growth. This challenge can be circumvented in a devised and demonstrated here, with ab initio calculations, strategy. Naturally present 1D-defects, the step-edges on h-BN substrate surface, enable boron epitaxial assembly, reduce the nucleation dimensionality and lower the barrier by an order of magnitude (to 1.1 eV or less), yielding v1/9 phase. Weak borophene adhesion to the insulator makes it readily accessible for comprehensive property tests or transfer into the device setting.

description: It is proved that for general, not necessarily periodic quasi one dimensional systems, the band position operator corresponding to an isolated part of the energy spectrum has discrete spectrum and its eigenfunctions have the same spatial localization as the corresponding spectral projection. As a consequence, an eigenbasis of the band position operator provides a basis of optimally localized (generalized) Wannier functions for quasi one dimensional systems, thus proving the "strong conjecture" of Marzari and Vanderbilt. If the system has some translation symmetries (e.g. usual translations, screw transformations), they are "inherited" by the Wannier basis.

description: The exact metric of a moving Kerr black hole with an arbitrary constant velocity is derived in Kerr-Schild coordinates. We then calculate the null equatorial gravitational deflection caused by a radially moving Kerr source up to the second post-Minkowskian order, acting as an application of the weak field limit of the metric. The bending angle of light is found to be consistent with the result given in the previous works.

description: The optomechanical character of molecules was discovered by Raman about one century ago. Today, molecules are promising contenders for high-performance quantum optomechanical platforms because their small size and large energy-level separations make them intrinsically robust against thermal agitations. Moreover, the precision and throughput of chemical synthesis can ensure a viable route to quantum technological applications. The challenge, however, is that the coupling of molecular vibrations to environmental phonons limits their coherence to picosecond time scales. Here, we improve the optomechanical quality of a molecule by several orders of magnitude through phononic engineering of its surrounding. By dressing a molecule with long-lived high-frequency phonon modes of its nanoscopic environment, we achieve storage and retrieval of photons at millisecond time scales and allow for the emergence of single-photon strong coupling in optomechanics. Our strategy can be extended to the realization of molecular optomechanical networks.
