description: With non-invasive methods, we investigate ground and excited states of a lateral quantum dot. Charge detection via a quantum point contact is used to map the dot dynamics in a regime where the current through the dot is too low for transport measurements. In this way we investigate and compare the tunneling rates from the dot to source and drain. We find a symmetry line on which the tunneling rates to both leads are equal. In this situation ground states as well as excited states influence the mean charge of the dot. A detailed study in this regime reveals that the coupling symmetry depends on the number of states contributing to transport and on the spatial distribution of individual states.

description: Nanolasers are considered ideal candidates for communications and data processing at chip-level thanks to their extremely reduced footprint, low thermal load and potentially outstanding modulation bandwidth, which in some case has been numerically estimated to exceed hundreds of GHz. The few experimental implementations reported to date, however, have so-far fallen very short of such predictions, whether because of technical difficulties or of overoptimistic numerical results. We propose a methodology to study the physical characteristics which determine the system's robustness and apply it to a general model, using numerical simulations of large-signal modulation. Changing the DC pump values and modulation frequencies, we further investigate the influence of intrinsic noise, considering, in addition, the role of cavity losses. Our results confirm that significant modulation bandwidths can be achieved, at the expense of large pump values, while the often targeted low bias operation is strongly noise- and bandwidth-limited. This fundamental investigation suggests that technological efforts should be oriented towards enabling large pump rates in nanolasers, whose performance promises to surpass microdevices in the same range of photon flux and input energy.

description: High-resolution mapping of the intra-cluster medium (ICM) up to high redshift and down to low masses is crucial to derive accurate mass estimates of the galaxy cluster and to understand the systematic effects affecting cosmological studies based on galaxy clusters. We present a spatially-resolved Sunyaev-Zel'dovich (SZ)/X-ray analysis of ACT-CL J0215.4+0030, a high redshift ($z=0.865$) galaxy cluster of intermediate mass ($M_{500}\simeq3.5\times10^{14}\;\mathrm{M_\odot}$) observed as part of the ongoing NIKA2 SZ Large Program, a follow up of a representative sample of objects at $0.5 \leqslant z \leqslant 0.9$. In addition to the faintness and small angular size induced by its mass and redshift, the cluster is contaminated by point sources that significantly affect the SZ signal. Therefore, this is an interesting case study for the most challenging sources of the NIKA2 cluster sample. We present the NIKA2 observations of this cluster and the resulting data. We reconstruct the ICM pressure profile by performing a joint analysis of the SZ signal and of the point sources in the NIKA2 150 GHz map. We obtain high-quality estimates of the ICM thermodynamical properties with NIKA2. We compare the pressure profile extracted from the NIKA2 map to the pressure profile obtained from X-ray data only by deprojecting XMM-Newton observations of the cluster. We combine the NIKA2 pressure profile with the X-ray deprojected density to extract detailed information on the ICM. The radial distribution of its thermodynamic properties indicate that the cluster has a disturbed core. The hydrostatic mass of the cluster is to be compatible with estimations from SZ and X-rays scaling relations. We conclude that the NIKA2 SZ large program can deliver quality information on the thermodynamics of the ICM even for one of its faintest clusters, after a careful treatment of the contamination by point sources.

The methodology of arrangement: a case study of the Department of the Provincial Secretary of British Columbia
Creators: name: Carter, Michael Charles
Publisher: name: University of British Columbia
Year: 2009

description: Arrangement is an important archival activity that precedes other important archival activities including description and access. Its objective is to identify the external and internal structures of a fonds. However, despite its importance, archivists have had difficulty establishing a standard method of arrangement that fully achieves its objective. This study views arrangement as a form of methodology bridging archival theory and practice. Arrangement must therefore be in accordance with archival theory yet be applicable in practical terms. The study first establishes the terms of analysis in regards to archival theory, and, in particular, the concept of the fonds. Difficulties in the practice of arrangement are then examined. These difficulties include (1) identifying the levels of arrangement, (2) identifying when an entity has sufficient autonomy to create a fonds, (3) identifying the provenance of record series that have been in the custody of many agencies, and (4) dealing with the effects that changes to the external structure of a fonds have on record series. The main methods of arrangement, that have been utilized throughout the archival world in the last 50 years, including the record group, fonds method and series system, are then assessed to determine how closely each aligns with archival theory and how well they perform in practical terms. A method of arrangement is then devised using the basic attributes of both the fonds and series system methods. The Department of the Provincial Secretary, of British Columbia, is the subject of a case study to confirm the validity of the methodology. The study first examines the external structure of the Department through the concepts of function, competence and organizational structure. It then studies the external structure through the concepts of functional series and documentary series. The study concludes by examining some of the implications of the method for various aspects of archival practice.

State distinguishability under weak measurement and post-selection: A unified system and device perspective
Creators: name: Stammer, Philipp
Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We quantify the disturbance of a quantum state undergoing a sequence of observations, and particularly focus on a weak measurement followed by post-selection and compare these results to the projective counterpart. Taking into account the distinguishability of both, the system and the device, we obtain the exact trade-off between the system state disturbance and the change of the device pointer state. We show that for particular post-selection procedures the coupling strength between the system and the device can be significantly reduced without loosing measurement sensitivity, which is directly transferred to a reduced state disturbance of the system. We observe that a weak measurement alone does not provide this advantage but only in combination with post-selection a significant improvement in terms of increased measurement sensitivity and reduced state disturbance is found. We further show that under realistic experimental conditions this state disturbance is small, whereas the exact post-selection probability is considerably larger than the approximate value given by the overlap of the initial and final state when neglecting the system state disturbance.
Regulatory and Institutional Framework for the Conservation of Coral Reefs in Bangladesh: A Critical Review

description: The coral reefs' crisis is increasing, with the combined effects of natural and anthropogenic disturbances. It is predicted that coral reefs could extinct soon from the world. Bangladesh has only one coral Island named Saint Martin, locally known as 'Narikel Jinjira'. This is one of the most popular tourist spots in Bangladesh, entertaining thousands of tourists per year due to its unique landscape, blue water, and coral colonies' presence. This Island lost most of the coral in recent times. The coral reef ecosystem management needs to focus on the reformation of the legal and institutional frameworks for enhancing the local administration's capabilities to address the adverse effects of the stressors and promote the ecosystem services by improving the resilience. The study aims at analysing the existing institutional and legal frameworks for conserving the coral reefs. To collect data, fieldwork was conducted at Saint Martin Island and Teknaf Upazila. The related literature on legal documents was reviewed critically. It is found that despite having legal mechanisms and institutional frameworks, non-compliances with laws and poor coordination among different sectors are widespread, resulting in severe degradation of coral resources. In most of the laws, robust institutional arrangements were ignored. The study recommends integrating the legal and institutional frameworks governing the environment, tourism, and fisheries sectors. Effective marine governance, increasing coordination among different sectors, amending some existing rules, and activating MCS (monitoring, control, surveillance) system can improve the scenario.
Study of Loads on Four Box Culverts on the Alexandria - Ashland Highway

Subjects: subject: Transportation Engineering

description: Culverts on the Alexandria - Ashland Highway (AA Highway) were designed with modifications recommended in a 1984 report titled "Analysis of Loads and Settlements For Reinforced Concrete Culverts". In 1986, the Kentucky Department of Highways requested the Kentucky Transportation Center monitor selected culverts on the AA Highway. The objectives of this study were to compare predicted loads on the culverts to measured loads and to monitor differential settlement of the embankment near the culvert.  Four culverts with varied box dimensions and embankment heights were selected. Each of the four culverts was instrumented with earth pressure meters on the sidewalls and top slab. Settlement monitoring instruments were placed in the embankment at each culvert.  Design loads for each culvert sidewall and top slab were calculated. Design loads and dead loads due to the weight of the embankment were compared to the measured loads. The new design method used by the Department of Highways was found to be very accurate for predicting top slab loads on positive projecting culverts on unyielding foundations. The Department of Highways method significantly underpredicted the top slab load for a culvert on a yielding foundation.  The Department of Highways does not include charts from the 1984 report for predicting sidewall loads. Charts from the 1984 report appear to be reasonably accurate, especially as sidewall loads increase.

description: Solutions relying on artificial intelligence are devised to predict data patterns and answer questions that are clearly defined, involve an enumerable set of solutions, clear rules, and inherently binary decision mechanisms. Yet, as they become exponentially implemented in our daily activities, they begin to transcend these initial boundaries and to affect the larger sociotechnical system in which they are situated. In this arrangement, a solution is under pressure to surpass true or false criteria and move to an ethical evaluation of right and wrong. Neither algorithmic solutions, nor purely humanistic ones will be enough to fully mitigate undesirable outcomes in the narrow state of AI or its future incarnations. We must take a holistic view. In this paper we explore the construct of infrastructure as a means to simultaneously address algorithmic and societal issues when designing AI.

description: Berry's phase, which is associated with the slow cyclic motion with a finite period, looks like a Dirac monopole when seen from far away but smoothly changes to a dipole near the level crossing point in the parameter space in an exactly solvable model. This topology change of Berry's phase is visualized as a result of lensing effect; the monopole supposed to be located at the level crossing point appears at the displaced point when the variables of the model deviate from the precisely adiabatic movement. The effective magnetic field generated by Berry's phase is determined by a simple geometrical consideration of the magnetic flux coming from the displaced Dirac monopole.
description: 14 pages, 4 figures. The agreement of Berry's phase with the solid angle drawn by a spin vector in the case of a two-component spinor is explained in connection with the lensing effect. This version is going to appear in Phys. Rev. D

description: The muffin-tin model of an effective-mass electron interacting with magnetic ions in semiconductors is extended to incorporate electrostatic potentials that are present in the case of Mn-based III-V compounds (${Ga}_{1-x} {Mn}_x {N}$, ${Ga}_{1-x} {Mn}_x {As}$). Since the conduction band electron is repelled from negatively charged magnetic ions and attracted by compensating donors, the \emph{apparent} value of the s-d exchange coupling $N_0 α$ is reduced. It is shown that the magnitude of this effect increases when x diminishes. Our model may explain an unusual behavior of electron spin splitting observed recently in those two materials in the Mn concentration range x <= 0.2%.

description: As tokamaks are designed and built with increasing levels of stored energy in the plasma, disruptions become increasingly dangerous. It has been reported that 95% of the disruptions in the Joint European Torus (JET) tokamak with the ITER-like wall are preceded by the growth of large locked islands, and these large islands are mostly produced by off-normal events other than neoclassical tearing modes. This paper discusses the use of RF current drive to stabilize large islands, focusing on nonlinear effects that appear when relatively high powers are used to stabilize large islands. An RF current condensation effect can concentrate the RF driven current near the center of the island, increasing the efficiency of the stabilization. A nonlinear shadowing effect can hinder the stabilization of islands if the aiming of the ray trajectories does not properly consider the nonlinear effects.

description: Inducing a meaningful structural representation from one or a set of dialogues is a crucial but challenging task in computational linguistics. Advancement made in this area is critical for dialogue system design and discourse analysis. It can also be extended to solve grammatical inference. In this work, we propose to incorporate structured attention layers into a Variational Recurrent Neural Network (VRNN) model with discrete latent states to learn dialogue structure in an unsupervised fashion. Compared to a vanilla VRNN, structured attention enables a model to focus on different parts of the source sentence embeddings while enforcing a structural inductive bias. Experiments show that on two-party dialogue datasets, VRNN with structured attention learns semantic structures that are similar to templates used to generate this dialogue corpus. While on multi-party dialogue datasets, our model learns an interactive structure demonstrating its capability of distinguishing speakers or addresses, automatically disentangling dialogues without explicit human annotation.

description: We discuss role of partially gravitating scalar fields, scalar fields whose energy-momentum tensors vanish for a subset of dimensions, in dynamical compactification of a given set of dimensions. We show that the resulting spacetime exhibits a factorizable geometry consisting of usual four-dimensional spacetime with full Poincare invariance times a manifold of extra dimensions whose size and shape are determined by the scalar field dynamics. Depending on the strength of its coupling to the curvature scalar, the vacuum expectation value (VEV) of the scalar field may or may not vanish. When its VEV is zero the higher dimensional spacetime is completely flat and there is no compactification effect at all. On the other hand, when its VEV is nonzero the extra dimensions get spontaneously compactified. The compactification process is such that a bulk cosmological constant is utilized for curving the extra dimensions.

description: We use Monte Carlo simulations and assumptions from evolutionary game theory in order to study the evolution of words and the population dynamics of a system comprising two interacting species which initially speak two different languages. The species are characterized by their identity, vocabulary and have different initial fitness, i.e. reproduction capability. The questions we want to answer are: a. Will the different initial fitness lead to a permanent advantage? b. Will this advantage affect the vocabulary of the species or the population dynamics? c. How will the spatial distributions of the species be affected? Does the system exhibit pattern formation or segregation? We show that an initial fitness advantage, although is very quickly balanced, leads to better spatial arrangement and enhances survival probabilities of the species. In most cases the system will arrive at a final state where both languages coexist. However, in cases where one species greatly outnumbers the other in population and fitness, then only one species survives with its final language having a slightly richer vocabulary than its initial language. Thus, our results offer an explanation for the existence and origin of synonyms in all currently spoken languages.

Activated macrophages decrease rat cardiac myocyte contractility : importance of ICAM-1 dependent adhesion
Creators: name: Simms, Matthew G.
Publisher: name: University of British Columbia
Year: 2009

description: Macrophages are found in the heart as part of the inflammatory response. Our goal was to determine whether macrophages could contribute to myocardial dysfunction. Rat ventricular myocytes were isolated using a collagenase perfusion system and cultured for 24 hours. Then myocytes were co-cultured with elicited peritoneal macrophages in media alone or in media containing TNFα IL-1β or endotoxin for 4 hours. Myocytes were electrically stimulated and fractional shortening was determined using videomicroscopy. When myocytes alone were challenged with TNFα, or LPS, fractional shortening did not decrease. When macrophages were prevented from adhering to myocytes by well inserts, TNFα and LPS did not have an effect. Fractional shortening of myocytes decreased from 20.3 ± 1.1% in unchallenged macrophage-myocyte co-cultures, without inserts, to 15.3 ± 1.1% and 15.1 ±1.8% when challenged for 4 hours with TNFα or endotoxin respectively (p<0.05). After 4 hours, the challenged myocytes had a mean adherence of 4.2 ± 0.2 macrophages compared to 2.6 ± 0.3 for controls (p<0.05). The number of adherent macrophages was associated with the decrease in fractional shortening. ELISA showed dose dependent ICAM-1 expression on myocytes, while VCAM-1 did not induce measurable expression. Antibody to ICAM-1 reduced macrophage adherence and prevented the decrease in fractional shortening. The decrease in fractional shortening was also prevented by anti-TNFα, desferoxamine, SOD, and L-NAME. These results suggest that activated macrophages adhere to cardiac myocytes via ICAM-1 and adherent macrophages decrease cardiac myocyte contractile function via TNFα, oxygen free radicals, and nitric oxide.

description: We embed Nelson's stochastic quantization in the Schwartz-Meyer second order geometry framework. The result is a non-perturbative theory of quantum mechanics on (pseudo)-Riemannian manifolds. Within this approach, we derive stochastic differential equations for massive spin-0 test particles charged under scalar potentials, vector potentials and gravity. Furthermore, we derive the associated Schrödinger equation. The resulting equations show that massive scalar particles must be conformally coupled to gravity in a theory of quantum gravity. We conclude with a discussion of some prospects of the stochastic framework.

description: 3He-rich solar energetic particles (SEPs) are believed to be accelerated in solar flares or jets by a mechanism that depends on the ion charge-to-mass (Q/M) ratio. It implies that the flare plasma characteristics (e.g., temperature) may be effective in determining the elemental abundances of 3He-rich SEPs. This study examines the relation between the suprathermal (<0.2 MeV/nuc) abundances of the He-Fe ions measured on the Advanced Composition Explorer and temperature in the solar sources for 24 3He-rich SEP events in the period 2010-2015. The differential emission measure technique is applied to derive the temperature of the source regions from the extreme ultraviolet imaging observations on the Solar Dynamics Observatory. The obtained temperature distribution peaks at 2.0-2.5 MK that is surprisingly consistent with earlier findings based on in-situ elemental abundance or charge state measurements. We have found a significant anti-correlation between 3He/4He ratio and solar source temperature with a coefficient -0.6. It is most likely caused by non-charge-stripping processes, as both isotopes would be fully ionized in the inferred temperature range. This study shows that the elemental ratios 4He/O, N/O, Ne/O, Si/O, S/O, Ca/O, Fe/O generally behave with temperature as expected from abundance enhancement calculations at ionization equilibrium. The C and Mg, the two species with small changes in the Q/M ratio in the obtained temperature range, show no such behavior with temperature and could be influenced by similar processes as for the 3He/4He ratio.

Lanczos - Einstein - Petiau: From Dirac's equation to nonlinear wave mechanics

description: In 1929 Lanczos showed how to derive Dirac's equation from a more fundamental system that predicted that spin 1/2 particles should come in pairs. Today, these pairs can unambiguously be interpreted as isospin doublets. From the same fundamental equation, Lanczos derived also the correct form of the wave equation of massive spin 1 particles that would be rediscovered in 1936 by Proca. Lanczos's fundamental system was put in Lagrangian form and generalized in 1933 by Einstein and Mayer, who used the semivector instead of the quaternion formalism. Although they not did study all possible solutions, Einstein and Mayer showed that the doublets consisted of particles with different mass and charge. In fact, there are two main classes of doublets: proton/neutron and electron/neutrino pairs.

A unified picture of ferromagnetism, quasi-long range order and criticality in random field models

Year: 2005
Subjects: subject: Other Condensed Matter (cond-mat.other)

description: By applying the recently developed nonperturbative functional renormalization group (FRG) approach, we study the interplay between ferromagnetism, quasi-long range order (QLRO) and criticality in the $d$-dimensional random field O(N) model in the whole ($N$, $d$) diagram. Even though the "dimensional reduction" property breaks down below some critical line, the topology of the phase diagram is found similar to that of the pure O(N) model, with however no equivalent of the Kosterlitz-Thouless transition. In addition, we obtain that QLRO, namely a topologically ordered "Bragg glass" phase, is absent in the 3--dimensional random field XY model. The nonperturbative results are supplemented by a perturbative FRG analysis to two loops around $d=4$.

Double peaks of gravitational wave spectrum induced from inflection point inflation

description: We investigate the possibility to induce double peaks of gravitational wave(GW) spectrum from primordial scalar perturbations in inflationary models with three inflection points.Where the inflection points can be generated from a polynomial potential or generated from Higgs like $ϕ^4$ potential with the running of quartic coupling.In such models, the inflection point at large scales predicts the scalar spectral index and tensor-to-scalar ratio consistent with current CMB constraints, and the other two inflection points generate two large peaks in the scalar power spectrum at small scales, which can induce GWs with double peaks energy spectrum. We find that for some choices parameters the double peaks spectrum can be detected by future GW detectors, and one of the peaks around $f\simeq10^{-9}\sim10^{-8}$Hz can also explain the recent NANOGrav signal. Moreover, the peaks of power spectrum allow for the generation of primordial black holes, which account for a significant fraction of dark matter.
