description: This study aimed to investigate the dynamic changes in the platelets of patients with severe heatstroke and the impact of these changes on the occurrence of disseminated intravascular coagulation (DIC) and prognosis in them. This retrospective cohort study conducted at two tertiary hospitals recruited 264 patients with severe heatstroke. Logistic regression was used to analyze the association between platelet counts and DIC. The receiver operating characteristic (ROC) curve was used to evaluate the predictive performance of platelets count for DIC occurrence. We used mediation effect to analysis the role of DIC as a mediating variable to mediate the relationship between platelet count decrease after 24 hours and death. There were 214 patients with lower platelet counts compared to admission (107 × 109/L[69,168] vs.171 × 109/L[126,215], p < 0.001). The DIC patients had lower platelet counts than the non-DIC patients when measured in the emergency department and after 24 hours. The platelet count decrease after 24 hours was a risk factor for DIC (odds ratio [OR] = 2.710, 95% confidence interval [CI] = 1.069–6.869). The results of the ROC curve revealed that the predictive performance of the platelet count after 24 hours (area under the curve [AUC] = 0.8685, 95% CI = 0.8173–0.9197) was significantly better than that of the platelet count measured in the emergency department (AUC = 0.7080, 95% CI = 0.6345–0.7815). Mediation analyses showed that PLT decrease after 24 hours did not directly lead to death, but can indirectly cause death by inducing the development of DIC. Decreased platelet count is an independent risk factor for DIC in patients with severe heatstroke. Although the platelet counts measured in the emergency department and after 24 hours show a good predictive performance for DIC occurrence, the prediction performance of the latter is better.

description: We derive analytic merger rates for dark-matter haloes within the framework of the Extended Press-Schechter (EPS) formalism. These rates become self-consistent within EPS once we realize that the typical merger in the limit of a small time-step involves more than two progenitors, contrary to the assumption of binary mergers adopted in earlier studies. We present a general method for computing merger rates that span the range of solutions permitted by the EPS conditional mass function, and focus on a specific solution that attempts to match the merger rates in N-body simulations. The corrected EPS merger rates are more accurate than the earlier estimates of Lacey & Cole, by ~20% for major mergers and by up to a factor of ~3 for minor mergers of mass ratio 1:10^4. Based on the revised merger rates, we provide a new algorithm for constructing Monte-Carlo EPS merger trees, that could be useful in Semi-Analytic Modeling. We provide analytic expressions and plot numerical results for several quantities that are very useful in studies of galaxy formation. This includes (a) the rate of mergers of a given mass ratio per given final halo, (b) the fraction of mass added by mergers to a halo, and (c) the rate of mergers per given main progenitor. The creation and destruction rates of haloes serve for a self-consistency check. Our method for computing merger rates can be applied to conditional mass functions beyond EPS, such as those obtained by the ellipsoidal collapse model or extracted from $N$-body simulations.

description: Study of far-from-equilibrium thermalization dynamics in quantum materials, including the dynamics of different types of quasiparticles, is becoming increasingly crucial. However, the inherent complexity of either the full quantum mechanical treatment or the solution of the scattering integral in the Boltzmann approach, has significantly limited the progress in this domain. In our previous work we had developed a solver to calculate the scattering integral in the Boltzmann equation. The solver is free of any approximation (no linearisation of the scattering operator, no close-to-equilibrium approximation, full non-analytic dispersions, full account of Pauli factors, and no limit to low order scattering) \cite{Michael}. Here we extend it to achieve a higher order momentum space convergence by extending to second degree basis functions.cWe further use an adaptive time stepper, achieving a significant improvement in the numerical performance. Moreover we show adaptive time stepping can prevent intrinsic instabilities in the time propagation of the Boltzmann scattering operator. This work makes the numerical time propagation of the full Boltzmann scattering operator efficient, stable and minimally reliant on human supervision.

description: This article gives an overview of the tradition of setting Japanese protest poetry to music since 1945 and examines the relationship between the socio-political movement, poetry and music. In particular, it deals with the origin and development of the Utagoe movement, established shortly after the World War II, as well as the musical adaptation of politically relevant poetry, which has its origin in the tradition of Brecht’s song. These forms of setting Japanese protest poetry to music are associated with the poetic-musical works that were written immediately after the nuclear power plant accident in Fukushima in 2011.

description: The purpose of the dissertation is the evaluation of the implemented systems and settlement’s works used by Trikala’s Forest Service. Delineated upland watersheds of streams in the research area (Trikala’s prefecture), searched the projects of the Forest Service, identified settlement systems that applied, was made field observation and recording of some representatives projects and appraised the result. In most, the projects were successful, have stabilized largely river beds and slopes and reduced the volume of sediment. Found a great adaptation to the environment, fragmented structures, local and not global basin’s management. The residential development, the grazing and the extensive farming pressurize. The management of streams is a complex problem, neglected by the state and with lack of funding. The settlement’s system applied in most cases, is the French Dasotechniko system with different variations. Moreover, there is no implementation of new types of systems - dams sorting by practitioners (Forest Service and private). The forest service should be modernized with new technologies, to organize the files and present its work. The target of the Forest Service should be to lift all of degraded watersheds.

description: Particle systems admit a variety of tensor product structures (TPSs) depending on the complete system of commuting observables chosen for the analysis. Different notions of entanglement are associated with these different TPSs. Global symmetry transformations and dynamical transformations factor into products of local unitary operators with respect to certain TPSs and not with respect to others. Symmetry-invariant and dynamical-invariant TPSs and corresponding measures of entanglement are defined for particle scattering systems.

description: Demand forecasting of hierarchical components is essential in manufacturing. However, its discussion in the machine-learning literature has been limited, and judgemental forecasts remain pervasive in the industry. Demand planners require easy-to-understand tools capable of delivering state-of-the-art results. This work presents an industry case of demand forecasting at one of the largest manufacturers of electronics in the world. It seeks to support practitioners with five contributions: (1) A benchmark of fourteen demand forecast methods applied to a relevant data set, (2) A data transformation technique yielding comparable results with state of the art, (3) An alternative to ARIMA based on matrix factorization, (4) A model selection technique based on topological data analysis for time series and (5) A novel data set. Organizations seeking to up-skill existing personnel and increase forecast accuracy will find value in this work.

description: COVID-19 infection is not limited to medical aspects, but may have significant negative impacts on education, tourism, the economy as well as sociocultural, ethical, and legal aspects. We aimed to assess the multidimensional impact of the COVID-19 pandemic on pediatricians by examining their COVID-19 infection, domestic life and quarantine, as well as work patterns, educational activities, and psychosocial impact. An online survey consisted of seven sections and 68 questions was prepared through ‘Google Forms.’ The survey was sent via e-mail to physicians who are members of the National Pediatric Association of Turkey. The pandemic has affected pediatricians working in our country in a multifaceted aspect. They experienced significant anxiety/depression/stress, 8% of them felt it at a pathological level and were receiving treatment, and women and young pediatricians were more vulnerable to the pandemic. The more adequately informed about the disease, the more prepared for COVID-19 and lower levels of psychological distress, which emphasizes the importance of education and institutional continuing support. Our study showed that academic education was seriously disrupted and the satisfaction rate with virtual education was low. Although COVID-19 has less impact today, it has taught us that it is necessary to be ready for new pandemics in the future. The required measures should be taken urgently and effectively healthcare professionals should follow a rational and applicable disaster plan.

description: (Si)GeSn semiconductors are finally coming of age after a long gestation period. The demonstration of device quality epi-layers and quantum-engineered heterostructures has meant that tunable all-group IV Si-integrated infrared photonics is now a real possibility. Notwithstanding the recent exciting developments in (Si)GeSn materials and devices, this family of semiconductors is still facing serious limitations that need to be addressed to enable reliable and scalable applications. The main outstanding challenges include the difficulty to grow high crystalline quality layers and heterostructures at the desired Sn content and lattice strain, preserve the material integrity during growth and throughout device processing steps, and control doping and defect density. Other challenges are related to the lack of optimized device designs and predictive theoretical models to evaluate and simulate the fundamental properties and performance of (Si)GeSn layers and heterostructures. This Perspective highlights key strategies to circumvent these hurdles and bring this material system to maturity to create far-reaching new opportunities for Si-compatible infrared photodetectors, sensors, and emitters for applications in free-space communication, infrared harvesting, biological and chemical sensing, and thermal imaging.

description: We present results from {\em Chandra}/ACIS-S, {\em Spitzer}, {\em XMM-Newton}, {\em HST}, and VLA observations of the radio hot spots, extended environment, and nucleus of the nearby ($z$=0.0597) FR II radio galaxy 3C 33. This is a relatively low-power FR II radio galaxy, and so we expect, {\it a priori}, to detect a significant X-ray synchrotron component to the emission from the hot spots. We detect X-ray emission coincident with the two knots of polarized optical emission from the southern hot spot (SHS), as well as along the northwest arm of this hot spot. We also detect X-ray emission from two compact regions of the northern hot spot (NHS), as well as diffuse emission behind the radio peak. The X-ray flux density of the region at the tip of the southern hot spot, the most compact radio feature of the southern lobe, is consistent with the synchrotron self-Compton (SSC) process. The X-ray flux densities of the other three regions of the SHS and the two compact regions of the NHS are an order of magnitude or more above the predictions from either the SSC and inverse-Compton scattering of the CMB (IC/CMB) mechanisms, thus strongly disfavoring these scenarios unless they are far from equipartition ($B$ $\sim$4-14 times smaller than the equipartition values). The X-ray flux from the diffuse region behind the NHS is consistent with the IC/CMB prediction assuming a small departure from equipartition. We conclude that the X-ray emission is synchrotron emission from multiple populations of ultrarelativistic electrons unless these regions are far from equipartition. There must therefore be unresolved substructure within each knot, similar to that which is found in Chandra observations of nearby FR I jets such as Centaurus A and 3C 66B.

description: Following the results of our previous low frequency searches for extraterrestrial intelligence (SETI) using the Murchison Widefield Array (MWA), directed toward the Galactic Centre and the Orion Molecular Cloud (Galactic Anticentre), we report a new large-scale survey toward the Vela region with the lowest upper limits thus far obtained with the MWA. Using the MWA in the frequency range 98-128 MHz over a 17 hour period, a $\sim$400 deg$^2$ field centred on the Vela Supernova Remnant was observed with a frequency resolution of 10 kHz. Within this field there are six known exoplanets. At the positions of these exoplanets, we searched for narrow band signals consistent with radio transmissions from intelligent civilizations. No unknown signals were found with a 5sigma detection threshold. In total, across this work plus our two previous surveys, we have now examined 75 known exoplanets at low frequencies. In addition to the known exoplanets, we have included in our analysis the calculation of the Effective Isotropic Radiated Power (EIRP) upper limits toward over 10 million stellar sources in the Vela field with known distances from Gaia (assuming a 10 kHz transmission bandwidth).

description: Higgs sector of the Standard model (SM) is replaced by quantum flavor dynamics (QFD), the gauged flavor $SU(3)_f$ symmetry with scale $Λ$. Anomaly freedom requires addition of three $ν_R$. The approximate QFD Schwinger-Dyson equation for the Euclidean infrared fermion self-energies $Σ_f(p^2)$ has the spontaneous-chiral-symmetry-breaking solutions ideal for seesaw: (1) $Σ_f(p^2)=M_{fR}^2/p$ where three Majorana masses $M_{fR}$ of $ν_{fR}$ are of order $Λ$. (2) $Σ_f(p^2)=m_f^2/p$ where three Dirac masses $m_f=m_{(0)}1+m_{(3)}λ_3+m_{(8)}λ_8$ of SM fermions are {\it exponentially suppressed w.r.t. $Λ$}, and {\it degenerate for all SM fermions in $f$}. (1) $M_{fR}$ break $SU(3)_f$ symmetry completely; $m_{(3)},m_{(8)}$ superimpose the tiny breaking to $U(1) \times U(1)$. All flavor gluons thus acquire self-consistently the masses $\sim Λ$. (2) All $m_f$ break the electroweak $SU(2)_L \times U(1)_Y$ to $U(1)_{em}$. Symmetry partners of the composite Nambu-Goldstone bosons are the genuine Higgs particles: (1) Three $ν_{R}$-composed Higgses $χ_i$ with masses $\sim Λ$. (2) Two new SM-fermion-composed Higgses $h_3, h_8$ with masses $\sim m_{(3)}, m_{(8)}$, respectively. (3) The SM-like SM-fermion-composed Higgs $h$ with mass $\sim m_{(0)}$, the effective Fermi scale. $Σ_f(p^2)$-dependent vertices in the electroweak Ward-Takahashi identities imply: The axial-vector ones give rise to the $W$ and $Z$ masses at Fermi scale. The polar-vector ones give rise to the fermion mass splitting in $f$. At the present exploratory stage the splitting comes out unrealistic.

description: The cross section for prompt neutral and charged three pion production in pp interactions was measured at excess energies in the range 160 - 217 MeV. That comprises the first measurement of the pp->pp pi0pi0pi0 reaction and the comparison with the pp->pp pi+pi-pi0 reaction, in a very direct way. The experiment was performed above the eta meson production threshold and the cross section normalization was obtained from a concurrent measurement of the reaction pp->pp eta with the eta decaying into 3 pions. Since the same final states are selected, the measurement has a low systematical error. The measured cross section ratio sigma(pp->pp pi+pi-pi0)/sigma(pp->pp pi0\pi0\pi0) is compared to predictions of dominance of different isobars in the intermediate state.

B_{c2}(T) curves corresponding to the crystals that have T_c>20 K have positive curvature (like in some HTSC), and those of the crystals with T_c<15 K fall on the usual Werthamer-Helfand-Hohenberg curve. R(T) and X(T) dependences of the crystals with T_c~30 K and T_c~11 K are respectively linear (like in HTSC) and exponential (BCS) in the temperature range T << T_c. The experimental results are discussed in connection with the extended saddle point model by Abrikosov.

description: We develop an analytical forward model based on perturbation theory to predict the redshift-space galaxy overdensity at the field level given a realization of the initial conditions. We find that the residual noise between the model and simulated galaxy density has a power spectrum that is white on large scales, with size comparable to the shot noise. In the mildly nonlinear regime, we see a $k^2μ^2$ correction to the noise power spectrum, corresponding to larger noise along the line of sight and on smaller scales. The parametric form of this correction has been predicted on theoretical grounds before, and our simulations provide important confirmation of its presence. We have also modeled the galaxy velocity at the field-level and compared it against simulated galaxy velocities, finding that about $10\%$ of the galaxies are responsible for half of the rms velocity residual for our simulated galaxy sample.

Problems in the studies of Zhou oracle-bone scripts
Creators: name: Lin, Sen-Shou
Publisher: name: University of British Columbia
Year: 2009

description: This thesis focuses on three areas of problems in the studies of Zhouyuan oracle-bone inscriptions: the interpretations of inscriptions, identities of kings and the origins of four pieces of Zhouyuan oracle bones. Why these three are chosen is that in order to read the inscriptions correctly, we first have to understand the meanings of words. If the word "king" appears in the inscriptions, it is ideal that we know the time period to which these oracle bones belong, so the information from the inscriptions can be used correctly from historical perspective. The origins of four Zhouyuan oracle bones are discussed because the identities of the kings mentioned are important; if they were Shang kings, they were from the Shang; otherwise, from the Zhou, though other possibilities are not excluded. In Chapter One I give a general introduction to the features of the Zhou oracle bones and inscriptions, so the readers will have background information for the remainder of the thesis. The readers will see some of the problems facing the scholars of the oracle-bone studies. In Chapter Two I attempt to determine who the kings were on fourteen pieces of Zhou oracle bone, so that these oracle bones, as historical artifacts, can be periodized properly; also in Chapter Two, I provide interpretations on the functions and meanings of the words that some of the characters represent on these fourteen pieces, in order that the inscriptions can be fully understood. In Chapter Three, I seek to ascertain the origins of four pieces of Zhou oracle bones which have caused controversy: by identifying who the kings were on these four pieces, we will thus be able see whether they belonged to the Shang or the Zhou. Chapter Four is the conclusion of this thesis. Appendix One details the discoveries of Zhou oracle bones in various locations in China through the years. Appendix Two is my response to K. Takashima's recent article on the modal and aspectual particle qi ^ and whether it is applicable to the use of qi in the Zhou oracle-bone inscriptions. I conclude that his theory is generally applicable: qi functions as a modal and an aspectual particle; it also indicates that the diviners wanted, for the most part, the contemplated charges to be acceptable to the spirits.

description: We demonstrate that the sign structure of the t-J model on a hypercubic lattice is entirely different from that of a Fermi gas, by inspecting the high temperature expansion of the partition function up to all orders, as well as the multi-hole propagator of the half-filled state and the perturbative expansion of the ground state energy. We show that while the fermion signs can be completely gauged away by a Marshall sign transformation at half-filling, the bulk of the signs can be also gauged away in a doped case, leaving behind a rarified "irreducible" sign structure that can be enumerated easily by counting exchanges of holes with themselves and spins on their real space paths. Such a sparse sign structure implies a mutual statistics for the quantum states of the doped Mott insulator.

description: The capital increase constitutes a way of financing the public limited liability company. When the capital increases by consideration in cash, the shares must be offered on a pre-emptive basis to shareholders in proportion to the capital represented by their shares. The right of pre-emption is primarily aimed at protecting minority shareholders who suffer when the company issues new shares, as it reduces the proportion of their participation in the company. The right of pre-emption constitutes a guarantee for the shareholders that they will maintain unvaried their dynamic position in their company when the capital is increased by issuing new shares. However, the right of pre-emption may be restricted or withdrawn by decision of the general meeting. The Board shall be first required to present to such a meeting a written report indicating the reasons for restriction or withdrawal of the right of pre-emption and, at the same time, justifying the proposed issue price. The decision of the general meeting is valid provided that it is in accordance with the corporate interest, the principle of proportionality and the principle of equal treatment of shareholders. Τhe right of pre-emption is excluded by law, when the capital is increased by consideration other than in cash, unless the statute provides otherwise.

description: We show that in multidimensional gravity vector fields completely determine the structure and properties of singularity. It turns out that in the presence of a vector field the oscillatory regime exists for any number of spatial dimensions and for all homogeneous models. We derive the Poincaré return map associated to the Kasner indexes and fix the rules according to which the Kasner vectors rotate. In correspondence to a 4-dimensional space time, the oscillatory regime here constructed overlap the usual Belinski-Khalatnikov-Liftshitz one.

description: We develop a series of molecular dynamics computer simulations of liquid water, performed with a polarizable potential model, to calculate the spinodal line and the curve of maximum density inside the metastable supercooled region. After analysing the structural properties,the liquid spinodal line is followed down to T=210 K. A monotonic decrease is found in the explored region. The curve of maximum density bends on approaching the spinodal line. These results, in agreement with similar studies on non polarizable models of water, are consistent with the existence of a second critical point for water.

description: The case for double-bottom hadrons (tetraquarks and baryons), which are stable against strong and electromagnetic interactions is reviewed. Such hadrons can be produced in hadron colliders, such as the LHC, and future $e^+e^-$ colliders run at the Z-boson mass, often called Tera-Z factories. We estimate the production cross sections, lifetimes, and characteristic decay modes for their detection at these facilities.

description: We present a study of using machine learning to enhance hohlraum design for opacity measurement experiments. For opacity experiments we desire a hohlraum that, when its interior walls are illuminated by theNational Ignition Facility (NIF) lasers, will produce a high radiation flux that heats a central sample to a temperature that is constant over a measurement time window. Given a baseline hohlraum design and a computational model, we train a deep neural network to predict the time evolution of the radiation temperature as measured by the Dante diagnostic. This enables us to rapidly explore design space and determine the effect of adjusting design parameters. We also construct an "inverse" machine learning model that predicts the design parameters given a desired time history of radiation temperature. Calculations using the machine learning model demonstrate that improved performance over the baseline hohlraum would reduce uncertainties in experimental opacity measurements.

description: We demonstrate that, contrary to common wisdom, genuine multipartite entanglement (GME) can be abundantly generated from simple non-correlated many-electron states. We show that the extracted GME can be maximized via spin-independent transformations derived from the quantum Fourier transform. We further demonstrate the possibility of maximizing the GME through localized orbitals in a variety of realistic systems and correlated states. Towards the exploitation of potentially useful entanglement, we rationalize system-specific and universal features of the extracted GME.
A two-frequency acousto-optic modulator driver to improve the beam pointing stability during intensity ramps

description: We report on a scheme to improve the pointing stability of the first order beam diffracted by an acousto-optic modulator (AOM). Due to thermal effects inside the crystal, the angular position of the beam can change by as much as 1 mrad when the radio-frequency power in the AOM is reduced to decrease the first order beam intensity. This is done for example to perform forced evaporative cooling in ultracold atom experiments using far-off-resonant optical traps. We solve this problem by driving the AOM with two radio-frequencies $f_1$ and $f_2$. The power of $f_2$ is adjusted relative to the power of $f_1$ to keep the total power constant. Using this, the beam displacement is decreased by a factor of twenty. The method is simple to implement in existing experimental setups, without any modification of the optics.

description: We have studied the chemical potential shift and changes in the electronic density of states near the Fermi level ($E_F$) as a function of carrier concentration in Pr$_{1-x}$Ca$_x$MnO$_3$ (PCMO, $0.2 \le x \le 0.65$) through the measurements of photoemission spectra. The results showed that the chemical potential shift was suppressed for $x \agt 0.3$, where the charge exchange (CE)-type antiferromagnetic charge-ordered state appears at low temperatures. We consider this observation to be related to charge self-organization such as stripe formation on a microscopic scale in this composition range. Together with the previous observation of monotonous chemical potential shift in La$_{1-x}$Sr$_x$MnO$_3$, we conclude that the tendency toward the charge self-organization increases with decreasing bandwidth. In the valence band, spectral weight of the Mn 3$d$ $e_g$ electrons in PCMO was transferred from $\sim$ 1 eV below $E_F$ to the region near $E_F$ with hole doping, leading to a finite intensity at $E_F$ even in the paramagnetic insulating phase for $x \agt 0.3$, probably related with the tendency toward charge self-organization. The finite intensity at $E_F$ in spite of the insulating transport behavior is consistent with fluctuations involving ferromagnetic metallic states.

description: Η συγκεκριμένη μελέτη αποτελεί διπλωματική εργασία στα πλαίσια του μεταπτυχιακού προγράμματος σπουδών «Ειδίκευση στην Περιβαλλοντική εκπαίδευση». Αρχικά κρίθηκε σκόπιμο να μελετηθεί η γνώμη των μαθητών/τριών σχετικά με την ανακύκλωση ηλεκτρονικών συσκευών. Τα παιδιά είναι χρήστες ηλεκτρονικών συσκευών και έχει ενδιαφέρον να γίνει μια πρώτη καταγραφή των συσκευών που χειρίζονται, καθώς και του χρόνου που αφιερώνουν σε αυτές. Στην συνέχεια, έγινε προσπάθεια να διερευνηθούν οι γνώσεις τους αναφορικά με την ανακύκλωση γενικότερα, ενώ ιδιαίτερη αναφορά γίνεται στις στάσεις αλλά και στην πρόθεση συμμετοχής των μαθητών/τριών στην ανακύκλωση ηλεκτρονικών συσκευών. Επίσης, όλα τα παραπάνω στοιχεία συσχετίζονται με δημογραφικά στοιχεία όπως το επάγγελμα, το μορφωτικό επίπεδο των γονέων τους και τον αριθμό των μελών της οικογένειας τους.Διαπιστώθηκε με την ανάλυση των αποτελεσμάτων ότι οι μαθητές/τριες διαθέτουν μεγάλο εύρος ηλεκτρονικού εξοπλισμού. Η στατιστική ανάλυση των αποτελεσμάτων της έρευνας, με το κριτήριο x2 έδειξε ότι παρατηρείται στατιστικά σημαντική διαφορά στην πεποίθηση των μαθητών/τριών ότι η ανακύκλωση είναι ωφέλιμη για το περιβάλλον και την συμμετοχή τους στην ανακύκλωση ηλεκτρονικών συσκευών. Τέλος, υπάρχει στατιστικά σημαντική διαφορά ανάμεσα στο μορφωτικό επίπεδο των γονέων και στον τρόπο διαχείρισης των ηλεκτρονικών αποβλήτων.
description: This thesis’s is part of the fulfillment of the Master program «Specialisation in Environmental Education».Initially, we examined students’ views about e-recycling.Children are users of electronic devices and it was interesting to make a first inventory of the apparatuses they use, as well as the time they spend in their use.Student’s knowledge on recycling was also explored, and a special emphasis was given to their attitudes and intention to be involved in e-recycling. Data are related to demographics such as occupation and educational level of their parents and number of family’s members.By analyzing the results it was found that students have a range of electronic equipment.Results showed that that there is correlation to the belief of students that recycling is useful for the environment with their participation in e-recycling. Moreover, there is a correlation between parents’ educational level and student’s attitude towards recycling electronics.

description: Quantum states exhibiting single-particle entanglement (SPE) can encode and process quantum information more robustly than their multi-particle analogs. Understanding the vulnerability and resilience of SPE to disorder is therefore crucial. This letter investigates phase, coin, and position disorder via discrete-time quantum walks on odd and even cyclic graphs to study their effect on SPE. The reduction in SPE is insignificant for low levels of phase or coin disorder, showing the resilience of SPE to minor perturbations. However, SPE is seen to be more vulnerable to position disorder. We analytically prove that maximally entangled single-particle states (MESPS) at time step $t=1$ are impervious to phase disorder regardless of the choice of the initial state. Further, MESPS at timestep $t=1$ is also wholly immune to coin disorder for phase-symmetric initial states. Position disorder breaks odd-even parity and distorts the physical time cone of the quantum walker, unlike phase or coin disorder. SPE saturates towards a fixed value for position disorder, irrespective of the disorder strength at large timestep $t$. Furthermore, SPE can be enhanced with moderate to significant phase or coin disorder strengths at specific time steps. Interestingly, disorder can revive single-particle entanglement from absolute zero in some instances, too. These results are crucial in understanding single-particle entanglement evolution and dynamics in a lab setting.
