description: Injecting a sufficiently large energy density into an isolated many-particle system prepared in a state with long-range order will lead to the melting of the order over time. Detailed information about this process can be derived from the quantum mechanical probability distribution of the order parameter. We study this process for the paradigmatic case of the spin-1/2 Heisenberg XXZ chain. We determine the full quantum mechanical distribution function of the staggered subsystem magnetization as a function of time after a quantum quench from the classical Néel state. This provides a detailed picture of how the Néel order melts and reveals the existence of an interesting regime at intermediate times that is characterized by a very broad probability distribution.

description: In the current density functional theory of linear and nonlinear time-dependent phenomena, the treatment of exchange and correlation beyond the level of the adiabatic local density approximation is shown to lead to the appearance of viscoelastic stresses in the electron fluid. Complex and frequency-dependent viscosity/elasticity coefficients are microscopically derived and expressed in terms of properties of the homogeneous electron gas. As a first consequence of this formalism, we provide an explicit formula for the linewidths of collective excitations in electronic systems.

description: The quantum behaviour of electrons in materials lays the foundation for modern electronic and information technology. Quantum materials with novel electronic and optical properties have been proposed as the next frontier, but much remains to be discovered to actualize the promise. Here we report the first observation of topological quantum properties of chiral crystals in the RhSi family. We demonsrate that this material hosts novel phase of matter exhibiting nearly ideal topological surface properties that emerge as a consequence of the crystals' structural chirality or handedness. We also demonstrate that the electrons on the surface of this crystal show a highly unusual helicoid structure that spirals around two high-symmetry momenta signalling its topological electronic chirality. Such helicoid Fermi arcs on the surface experimentally characterize the topological charges of $\pm{2}$, which arise from the bulk chiral fermions. The existence of bulk high-fold degenerate fermions are guaranteed by the crystal symmetries, however, in order to determine the topological charge in the chiral crystals it is essential to identify and study the helical arc states. Remarkably, these topological conductors we discovered exhibit helical Fermi arcs which are of length $π$, stretching across the entire Brillouin zone and orders of magnitude larger than those found in all known Weyl semimetals. Our results demonstrate novel electronic topological state of matter on a structurally chiral crystal featuring helicoid Fermi arc surface states. The exotic electronic chiral fermion state realised in these materials can be used to detect a quantised photogalvanic optical response or the chiral magnetic effect and its optical version in future devices as described by G. Chang \textit{et.al.,} `Topological quantum properties of chiral crystals' Nature Mat. 17, 978-985 (2018).

High-resolution structural variants catalogue in a large-scale whole genome sequenced bovine family cohort data
Creators: name: Young-Lim, Lee
Publisher: name: Zenodo
Year: 2034

description: Structural variants (SVs) are chromosomal segments that differ between genomes, such as deletions, duplications, insertions, inversions and translocations. The genomics revolution enabled the discovery of sub-microscopic SVs via array and whole-genome sequencing (WGS) data, paving the way to unravel the functional impact of SVs. Recent human expression QTL mapping studies demonstrated that SVs play a disproportionally large role in altering gene expression, underlining the importance of including SVs in genetic analyses. Therefore, this study aimed to generate and explore a high-quality bovine SV catalogue exploiting a unique cattle family cohort data (total 266 samples, forming 127 trios).
This isn't a funeral
Creators: name: Lewis, Taylor Alyson
Publisher: name: No Publisher Supplied
Year: 2021

description: This Isn’t a Funeral engages with the poetics of social death and the ongoing conversation between legacy and memory complicated by inherited enslavement. Many parts of This Isn’t a Funeral function as an open letter to self and family, enacted as an elegy of the self that suggests what lies inherit in all elegies: a profound desire made real on the page. In the work, I argue against and around ideas of my body: my body in medical transition, my body as the site of politics regardless of my consent, and the memoratic parallels between what transition denotes about my body and what my Blackness denotes about the bodies of my ancestors without their consent, both in the past and in the present. Thematically, my manuscript speaks to the practice of Black male gathering; the work creates and witnesses a space in which Black men can come together and be held in the truth of their experiences. The speaker imagines conversations and meetings between Black men and their families separated by war, Emancipation, alcoholism, death, transphobia, and a culturally manufactured fear of vulnerability and shared connection. This Isn’t a Funeral lyrically argues that the site of the elegy simultaneously enacts the rebirth of its subject, that death is meaning-making rather than destruction, that both to love and to pray as Black nonbinary trans man is to engage in transformation that is then politicized and condemned.

description: We present microwave and infrared measurements on SmLa0.8Sr0.2CuO4-d, which are direct evidence for the existence of a transverse optical plasma mode, observed as a peak in the c-axis optical conductivity. This mode appears as a consequence of the existence of two different intrinsic Josephson couplings between the CuO2 layers, one with a Sm2O2 block layer, and the other one with a (La,Sr)O block layer. From the frequencies and the intensities of the collective modes we determine the value of the compressibility of the two dimensional electron fluid in the copper oxygen planes.

description: An experimental study for over expanded, perfectly-expanded and under-expanded supersonic jets at Mach 2 is presented to study the effectiveness of a static cylinder to reduce base drag. A static cylinder of diameter 2 mm located at 2 mm from the sidewall of a square duct and 8 mm from the converging-diverging square nozzle exit in the base region is installed as a passive control device. Base pressures in the wake flow after a sudden expansion of jets into a square nozzle have been measured. The length-width ratio of the duct is 10. The jets were operated at different nozzle pressure ratios in the range from 2 to 9. The flow field in the square duct was also observed for all cases. The static cylinder as a passive controller was found to reduce the base drag as high as 59 percent at NPR = 9 and 14 percent at NPR = 6. The base pressure depends on Mach number, area ratio, length to width ratio, and nozzle pressure ratio. When the flow from the nozzle is over expanded, the static control is ineffective till NPR is 6. The level of expansion plays a vital role. The flow flux in the square duct remains almost identical with and without control for most of the cases. However, at higher NPRs namely 6, 7.8, and 9 the control results in an increase as well as a decrease in the wall pressure along the duct. Passive control of the base flow is effective for higher NPRs. The flow field for higher NPR is dominated by the shock waves. Further, this phenomenon is visualized using a shadowgraph.

description: There is evidence that interface recombination in Cu2ZnSnS4 solar cells contributes to the open-circuit voltage deficit. Our hybrid density functional theory calculations suggest that electron-hole recombination at the Cu2ZnSnS4/CdS interface is caused by a deeper conduction band that slows electron extraction. In contrast, the bandgap is not narrowed for the Cu2ZnSnSe4/CdS interface, consistent with a lower open-circuit voltage deficit.

description: Recent advances in atomic manipulation techniques have provided a novel bottom-up approach to investigating the unconventional properties and complex phases of strongly correlated electron materials. By engineering artificial condensed matter systems containing tens to thousands of atoms with tailored electronic or magnetic properties, it has become possible to explore how quantum many-body effects---whose existence lies at the heart of strongly correlated materials---emerge as the size of a system is increased from the nanoscale to the mesoscale. Here we investigate both theoretically and experimentally the quantum engineering of nanoscopic Kondo lattices -- Kondo droplets -- that exemplify nanoscopic replicas of heavy-fermion materials. We demonstrate that by changing a droplet's real space geometry, it is possible to not only create coherently coupled Kondo droplets whose properties asymptotically approach those of a quantum-coherent Kondo lattice, but also to markedly increase or decrease the droplet's Kondo temperature. Furthermore we report on the discovery of a new quantum phenomenon -- the Kondo echo -- a signature of droplets containing Kondo holes functioning as direct probes of spatially extended, quantum-coherent Kondo cloud correlations.

description: In a recent paper, I defined the "standard multiparameter Bailey pair" (SMPBP) and demonstrated that all of the classical Bailey pairs considered by W.N. Bailey in his famous paper (\textit{Proc. London Math. Soc. (2)}, \textbf{50} (1948), 1--10) arose as special cases of the SMPBP. Additionally, I was able to find a number of new Rogers-Ramanujan type identities. From a given Bailey pair, normally only one or two Rogers-Ramanujan type identities follow immediately. In this present work, I present the set of $q$-difference equations associated with the SMPBP, and use these $q$-difference equations to deduce the complete families of Rogers-Ramanujan type identities.

description: The existence of fractional charges carrying the current is experimentally demonstrated. Using a 2-D electron system in high magnetic field, we measure the shot noise associated with tunneling in the fractional quantum Hall regime at Landau level filling factor 1/3. The noise gives a direct determination of the quasiparticle charge, which is found to be e*=e/3 as predicted by Laughlin. The existence of e/3 Laughlin quasiparticles is unambiguously confirmed by the shot noise to Johnson-Nyquist noise cross-over found for temperature e*V/2k.

Stimulated resonant inelastic x-ray scattering with chirped, broadband pulses

Year: 2018
Subjects: subject: Atomic Physics (physics.atom-ph)

description: We present an approach for initiating and tracing ultra-fast electron dynamics in core-excited atoms, molecules and solids. The approach is based on stimulated resonant inelastic x-ray scattering induced by a single, chirped, broadband XUV/x-ray pulse. A first interaction with this pulse prepares a core-excited state wave packet by resonant core-excitation. A second interaction with the pulse at a later time induces the transition to valence-excited states which is associated with stimulated emission. The preparation of the core-excited wave packet and the transition from the core-excited states to the valence-excited states occur at distinct chirp-dependent times. As a consequence, the stimulated emission carries information about the time evolution of the core-excited state wave packet.

description: Experimental investigation of supersonic base flow has been carried out to see the effect of the cylinder when rotated counter-clockwise inside the dead zone at variable locations near its base to control base pressure for different levels of expansion for area ratio 9. The cylinder of 2 mm diameter rotating counter-clockwise, when seen from the top, is mounted as a controller. Three locations are chosen from the sidewall of the square duct namely at 2, 4, 6 mm respectively, and one from the square nozzle exit at 8 mm in the base region to mount the controller. Base pressure in the recirculation zone and wall pressure along the square duct length has been measured with and without control. The experiments were carried out at Mach 2 for NPR 2, 3, 6, 7.8, and 8.5. Cylinder when rotated counter-clockwise as an active controller was found to reduce the base drag as high as 62 percent at NPR 8.5 when located near the duct wall and 50 percent when located away from the duct wall for the same NPR. For perfectly expanded flows at NPR 7.8 the reduction in base drag was approximately from 44 to 53 percent near the duct wall depending on the location of the controller. The active controller was up to 19 percent effective for over-expanded flows near the duct wall and up to 12 percent effective when located away from the duct wall. For under expanded flows at NPR 8.5 the base drag reduction was between 49 and 64 percent depending on the location of the controller. Also, the control did not adversely affect the flow field. Further flow visualization inside the duct was captured using a shadowgraph.

description: The coherent states that describe the classical motion of a mechanical oscillator do not have well-defined energy, but are rather quantum superpositions of equally-spaced energy eigenstates. Revealing this quantized structure is only possible with an apparatus that measures the mechanical energy with a precision greater than the energy of a single phonon, $\hbarω_\text{m}$. One way to achieve this sensitivity is by engineering a strong but nonresonant interaction between the oscillator and an atom. In a system with sufficient quantum coherence, this interaction allows one to distinguish different phonon number states by resolvable differences in the atom's transition frequency. Such dispersive measurements have been studied in cavity and circuit quantum electrodynamics where experiments using real and artificial atoms have resolved the photon number states of cavities. Here, we report an experiment where an artificial atom senses the motional energy of a driven nanomechanical oscillator with sufficient sensitivity to resolve the quantization of its energy. To realize this, we build a hybrid platform that integrates nanomechanical piezoelectric resonators with a microwave superconducting qubit on the same chip. We excite phonons with resonant pulses of varying amplitude and probe the resulting excitation spectrum of the qubit to observe phonon-number-dependent frequency shifts $\approx 5$ times larger than the qubit linewidth. Our result demonstrates a fully integrated platform for quantum acoustics that combines large couplings, considerable coherence times, and excellent control over the mechanical mode structure. With modest experimental improvements, we expect our approach will make quantum nondemolition measurements of phonons an experimental reality, leading the way to new quantum sensors and information processing approaches that use chip-scale nanomechanical devices.

description: Considering a $d$-wave superconductor being in proximity to a two-dimensional Weyl model, a topological superconductor with gapless edge states may be realized. We here demonstrate that the system can become topologically trivial when an additional d-density-wave order is also included. The edge states become gapped and may be detected in experiments. For this, the d-density-wave order can be detected experimentally, so that different scenarios for the pseudogap in high-T$_c$ superconductors may be distinguished. Moreover, this method may be used to detect various hidden orders through putting high-T$_c$ superconductors being in proximity to various topological nontrivial materials.

description: In the millimeter wave (30-300 GHz) and Terahertz (0.1-10 THz) frequency bands, high spreading loss and molecular absorption often limit the signal transmission distance and coverage range. In this paper, four directions to tackle the crucial problem of distance limitation are investigated, namely, a physical layer distance-aware design, ultra-massive MIMO communication, reflectarrays, and intelligent surfaces. Additionally, the potential joint design of these technologies is proposed to combine the benefits and possibly further extend the communication distance. Qualitative analyses and quantitative simulations are provided to illustrate the benefits of the proposed techniques and demonstrate the feasibility of mm-wave and THz band communications up to 100 meters in both line-of-sight and non-line-of-sight areas.

description: This paper presents a numerical and experimental study of increasing the performance coefficient (COP) of split AC (SAC) by reducing compressor work and increasing cooling capacity. Two phase ejector as an expansion device with a new design of dual evaporator temperature used. numerical methods apply the mathematical model developed in the EES software that is applied. Thermodynamic analysis is carried out to achieve ASHRAE Standard requirements for a minimum SAC with COP application of 3.5. The SAC system is filled with R-290 as a thermal fluid medium. Based on the simulation results a numerical model of the ejector is then produced and installed in a modified SAC system of cooling capacity of at least 9000 BTU/hour. An experimental test was conducted to investigate the actual performance of the ejector and its effect on the performance of the SAC system. The results showed that the two phase ejector with the new design of the dual evaporator temperature system was successful. When compared to standard split air conditioners using capillary tube expansion devices the tested ejector system contributes around 35% of power savings. The COP of the system can reach 5.5 which accounts for 39% of the increase in performance. Use of the constant ejector area COS-SAC dual temperature evaporator system which is intended to be applied for split AC to replace accumulator in standard ejector system has been successful.

description: We investigate the escape behavior of systems governed by the one-dimensional nonlinear diffusion equation $\partial_t ρ= \partial_x[\partial_x Uρ] + D\partial^2_x ρ^ν$, where the potential of the drift, $U(x)$, presents a double-well and $D, ν$ are real parameters. For systems close to the steady state we obtain an analytical expression of the mean first passage time, yielding a generalization of Arrhenius law. Analytical predictions are in very good agreement with numerical experiments performed through integration of the associated Ito-Langevin equation. For $ν\neq 1$ important anomalies are detected in comparison to the standard Brownian case. These results are compared to those obtained numerically for initial conditions far from the steady state.

description: Abstract

This research paper presents the design and implementation of a cost-effective, portable solar-powered mobile phone charger tailored for off-grid environments. The charger's design was meticulously crafted using Proteus software, allowing for detailed simulation and analysis before physical implementation. The implemented model was compared with the simulation output to validate its performance. The charger incorporates a buck converter with an output voltage of 5.05 V, a current rating of 1.51 A, and an output power of 7.61 W. These specifications were achieved through careful component selection and circuit optimization to ensure optimal charging efficiency while utilizing solar energy. The study also evaluates the charger's ability to harness and store solar energy efficiently, making it an environmentally friendly and sustainable solution for off-grid regions. The results showcase the successful realization of a low-cost, solar-powered mobile phone charger with promising implications for providing accessible energy solutions in areas lacking reliable power infrastructure.

description: The construction process is marred by project delays that tend to ruin the economies of nations worldwide. Studies pertaining to causes and effects of construction delays are plentiful, but solutions that was supposed to provide the results of this phenomenon (such as lean construction), is not seen to that scale. One reason for this is that delays are caused by time wastes at activity levels, and scholarly studies primarily don't deal at activity levels. Experience based heuristics play the most important role in fixing the duration of activates by managers. But, construction activities are prone to highly improbable & complex process flows, making heuristics unreliable. The reason being probability of one construction site condition and stakeholders, being similar to the next project is meagerly low. Thus experience gained by the project management personnel involved may not be handy in predicting actual durations and costs in the forthcoming project. The only practical solution would be fixation of cost and time standards for singular construction activities basing on the overall history of projects and personnel involved. On the long run globalizing or at least nationalizing heuristic data of delays and wastes would help in predicting future process. It can be achieved by proving a mechanism of the centralizing construction process into a single data entity at national level- Data Collection System (DCIS). As part of the system, synchronization of personnel and construction site data takes place at every instance a new construction process is activated anywhere in the concerned boundary of DCIS. Collection of inventory data, material data, labor data, stakeholder data, delay data, time waste data etc. is to form the epicenter of this data center. Data from heuristics should then be converted to mathematical distributions that can be used for predictions in future construction sites. This would result in giving better and better results as the process of data entry begins.

description: We consider an expansion of the ground state wavefunction of quantum lattice many-body systems in a basis whose states are tensor products of block-spin wavefunctions. We demonstrate by applying the method to the antiferromagnetic spin-1/2 chain that by selecting the most important many-body states the technique affords a severe truncation of the Hilbert space while maintaining high accuracy.

description: Spiral phase contrast is an important and convenient imaging processing technology in edge detection, and a broader field-of-view (FOV) of imaging is a long-pursuing aim to see more regions of the illumination objects. Compared with near-infrared (NIR) spectrum, the up-conversion imaging in visible spectrum benefits from the advantages of higher efficiency detection and lower potential speckle. FOV enhanced and spiral phase contrast up-conversion imaging processing methods by using second order nonlinear frequency up-conversion from NIR spectrum to visible spectrum in two different configurations are presented in this work. By changing the temperature of crystal, controllable spatial patterns of imaging with more than 4.5 times enhancement of FOV is realized in both configurations. Additionally, we present numerical simulations of the phenomenon, which agree well with the experimental observations. Our results provide a very promising way in imaging processing, which may be widely used in biomedicine, remote sensing and up-conversion monitoring.

description: Polarized infrared reflectivity measurements have been performed on single crystals of the spin-Peierls compound alpha'-NaV2O5 in the temperature range 20-300 K. Pronounced spectral features associated with the formation of the dimerized phase were detected both in the a- and b-polarizations (perpendicular and parallel to the spin-1/2 chains, respectively). The temperature dependence of a salient spectral line at 718 cm^-1 sharply rising below the transition temperature T_SP obeys a (1-T/T_SP)^(2beta) law with T_SP \simeq 34.3$K and beta \simeq 0.25. In addition, a continuum signal is observed in the whole temperature range in the a-polarized optical conductivity spectra. In order to interpret these results, calculations of the static dimerization and of the optical conductivity based on a mean-field and a dynamical treatment of the lattice respectively are proposed.

description: Detailed magneto-transport data on dense wires of $MgB_2$ are reported for applied magnetic fields up to 18 T. The temperature and field dependencies of the electrical resistivity are consistent with $MgB_2$ behaving like a simple metal and following a generalized form of Kohler's rule. In addition, given the generally high $T_c$ values and narrow resistive transition widths associated with $MgB_2$ synthesized in this manner, combined with applied magnetic fields of up to 18 T, an accurate and complete $H_{c2}(T)$ curve could be determined. This curve agrees well with curves determined from lower field measurements on sintered pellets and wires of $MgB_2$. $H_{c2}(T)$ is linear in $T$ over a wide range of temperature (7 K $\le~T~\le$ 32 K) and has an upward curvature for $T$ close to $T_c$. These features are similar to other high $κ$, clean limit, boron-bearing intermetallics: $YNi_2B_2C$ and $LuNi_2B_2C$.

description: In this paper we analyzed the light curve of the object KIC~3832716 observed during Kepler K1 mission. We showed that this previously known eclipsing binary is in fact quadruple system, in double eclipsing binary configuration on a long period orbit with the mass ratio of eclipsing binaries $0.7 \pm 0.3$. The system consists of eclipsing binary A with the orbital period of $P_A \sim 1.1419$\,d. Eclipsing binary A contains larger but less luminous secondary component in the post main sequence stage of its evolution consistent with an "Algol paradox" which can explain parameters of the components by mass transfer from secondary component after leaving the main sequence. Inspection of the light curve and eclipse time variations of the eclipsing binary A also indicates the presence of spots on the surface of secondary component with $57$\,d period of activity probably induced by longitudonal motion of the spots. The second eclipsing binary B with orbital period $P_B \sim 2.1703$\,d contains very dim secondary component with luminosity below 0.09\,$L_{\odot}$.

title: An effective detection strategy and determining critical habitat characteristics for Boreal Felt Lichen (Erioderma pedicellatum) in Newfoundland, Canada
Creators: name: Lauriault, Patrick
Publisher: name: Memorial University of Newofundland
Year: 2020

description: Boreal felt lichen (Erioderma pedicellatum) is a rare lichen that is listed as critically endangered by the IUCN. On the island of Newfoundland, Canada, the Central Avalon Forest Ecoregion is a hotspot for this species. The population in this region is relatively abundant, providing an opportunity to study its habitat requirements. I used occupied and unoccupied plots (each 5 m radius) to test critical habitat for boreal felt lichen. To ensure I effectively detected lichens in our plots, I developed a decoy lichen experiment to test the detection probability of these lichens. I applied the results from the decoy experiment to the habitat study. Although I could not consider time in the study, I discussed how the shortened lifespan of the host tree may constrain the temporal niche of boreal felt lichen. I identified critical habitat for boreal felt lichen, which will contribute to informed land use to help protect this population.
