description: GD 362 is a massive white dwarf with a spectrum suggesting a H-rich atmosphere which also shows very high abundances of Ca, Mg, Fe and other metals. However, for pure H-atmospheres the diffusion timescales are so short that very extreme assumptions have to be made to account for the observed abundances of metals. The most favored hypothesis is that the metals are accreted from either a dusty disk or from an asteroid belt. Here we propose that the envelope of GD 362 is dominated by He, which at these effective temperatures is almost completely invisible in the spectrum. This assumption strongly alleviates the problem, since the diffusion timescales are much larger for He-dominated atmospheres. We also propose that the He-dominated atmosphere of GD 362 is likely to be the result of the merger of a binary white dwarf.

description: With proton-proton collisions at PHENIX a variety of direct channels are used to probe the proton substructure. Of the many channels available at PHENIX, charged pion measurements are expected to have sensitivity of Delta g and thus help in the global analysis that will constrain it. We present a measurement of mid-rapidity charged pion production double longitudinal spin asymmetries (ALL) at the pT range of 5-10 GeV/c at collision energies of sqrt(s) = 200 GeV.

description: One of the difficulties related to the COVID-19 pandemic is the shifting from face-to-face to distance teaching. Both schools and universities had suddenly to organize on-line lectures. To perform laboratory practice even in this period, easily accessible materials, smartphones physics apps, on-line tools and devices can be used. In this paper a method to measure the gravitational acceleration studying the free falling body using Arduino board is presented.
Computability Closure: Ten Years Later

Subjects: subject: Logic in Computer Science (cs.LO)

description: The notion of computability closure has been introduced for proving the termination of higher-order rewriting with first-order matching by Jean-Pierre Jouannaud and Mitsuhiro Okada in a 1997 draft which later served as a basis for the author's PhD. In this paper, we show how this notion can also be used for dealing with beta-normalized rewriting with matching modulo beta-eta (on patterns à la Miller), rewriting with matching modulo some equational theory, and higher-order data types (types with constructors having functional recursive arguments). Finally, we show how the computability closure can easily be turned into a reduction ordering which, in the higher-order case, contains Jean-Pierre Jouannaud and Albert Rubio's higher-order recursive path ordering and, in the first-order case, is equal to the usual first-order recursive path ordering.

description: The acoustic radiation force produced by ultrasonic waves is the "workhorse" of particle manipulation in acoustofluidics. Nonspherical particles are also subjected to a mean torque known as the acoustic radiation torque. Together they constitute the mean-acoustic fields exerted on the particle. Analytical methods alone cannot calculate these fields on arbitrarily shaped particles in actual fluids and no longer fit for purpose. Here, a semi-analytical approach is introduced for handling subwavelength axisymmetric particles immersed in an isotropic Newtonian fluid. The obtained mean-acoustic fields depend on the scattering coefficients that reflect the monopole and dipole modes. These coefficients are determined by numerically solving the scattering problem. Our method is benchmarked by comparison with the exact result for a subwavelength rigid sphere in water. Besides, a more realistic case of a red blood cell immersed in blood plasma under a standing ultrasonic wave is investigated with our methodology.

description: Augmented reality (AR) in laparoscopic liver surgery needs key landmark detection in intraoperative 2D laparoscopic images and its registration with the preoperative 3D model created from CT/MRI data. Such AR techniques are vital to surgeons as they enable precise tumor localisation for surgical removal. A full resection of targeted tumor minimises the risk of recurrence. However, the task of automatic anatomical curve segmentation (considered as landmarks), and its registration to 3D models is a non-trivial and complex task. Most developed methods in this domain are built around traditional methodologies in computer vision. This challenge is designed to challenge participants to deploy machine learning methods for two tasks - a) task I: segmentation of key anatomical curves from laparoscopic video images and 3D model, and b) task 2: matching these segmented curves to the 3D liver model from volumetric data (CT/MR). Thus the challenge is aimed at segmenting anatomical curves such as ridges, liver contours and midline of ligament (supervised and semi-supervised), and 2D-3D registration problem (semi-supervised and unsupervised) between the segmented landmarks with the provided dense 3D point cloud of liver. Here, we will assess the quality of registration algorithms using widely used target registration errors while liver landmark segmentation will be evaluated-based on F1-score.
The double hypergeometric series for the partition function of the 2D anisotropic Ising model

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: In 1944 Lars Onsager published the exact partition function of the ferromagnetic Ising model on the infinite square lattice in terms of a definite integral. Only in the literature of the last decade, however, has it been recast in terms of special functions. Until now all known formulas for the partition function in terms of special functions have been restricted to the important special case of the isotropic Ising model with symmetric couplings. Indeed, the anisotropic model is more challenging because there are two couplings and hence two reduced temperatures, one for each of the two axes of the square lattice. Hence, standard special functions of one variable are inadequate to the task. Here, we reformulate the partition function of the anisotropic Ising model in terms of the Kampé de Fériet function, which is a double hypergeometric function in two variables that is more general than the Appell hypergeometric functions. Finally, we present hypergeometric formulas for the generating function of multipolygons of given length on the infinite square lattice, for isotropic as well as anisotropic edge weights. For the isotropic case, the results allow easy calculation, to arbitrary order, of the celebrated series found by Cyril Domb.

description: The puzzling behavior of the transition phase through a quantum dot can be understood in a natural way via a formation of the electron molecule in the quantum dot. In this case the resonance tunneling takes place through the quasi-stationary (doorway) state, which emerges when the number of electrons occupying the dot reaches a certain ``critical'' value, $N_{cr}$. Our estimation of this quantity agrees with the experimental data. The dependence of $N_{cr}$ on the dot's size is predicted as well.

description: The study draws evidences from classical Indian texts such as the Vedas, Upanishads and the Mahabharata, depicting how these ancient scriptures provide a rich foundation that bridges traditional knowledge with modern scientific advancements. It discusses in depth the contributions of renowned scholars such as Aryabhata, Kanada, Bhaskara II, Charaka, Panini, Patanjali and Sushruta, whose novel concepts have shaped contemporary scientific understanding. The paper highlights the subtle interconnections between ancient knowledge and contemporary fields such as biotechnology and life sciences. For example, while stem cell research is often viewed as a modern innovation, the story of Queen Gandhari and the sage Vyasa from the MahaBhārata hints at early concepts of cell culture and development. Similarly, the myth of the replacement of Lord Ganesha’s head with that of an elephant offers an ancient perspective on organ transplant practices that resonates with modern xenotransplantation techniques. In addition, this paper examines symbolic representations in Indian mythology, such as Ardhanarishvara, who symbolizes the unification of dualistic forces, similar to the genetic concept of non-disjunction. It also discusses Garbha Sanskar, an ancient practice that underlines the influence of parents’ mental states on foetal development, which parallels modern epigenetic theories.By combining historical and contemporary perspectives, this study underscores the enduring relevance of ancient Indian wisdom. It calls for a renewed appreciation of traditional knowledge and its potential contributions to current scientific research and technological advancements.

description: We explore the inflationary dynamics leading to formation of closed domain walls in course of evolution of an axion like particle (ALP) field whose Peccei-Quinn-like phase transition occurred well before inflationary epoch. Evolving after inflation, the domain walls may leave their imprint in stochastic gravitational waves background, in the frequency range accessible for the pulsar timing array measurements. We derive the characteristic strain power spectrum produced by the distribution of the closed domain walls and relate it with the recently reported NANOGrav signal excess. We found that the slope of the frequency dependence of the characteristic strain spectrum generated by the domain walls is very well centered inside the range of the slopes in the signal reported by the NANOGrav. Analyzing the inflationary dynamics of the ALP field, in consistency with the isocurvature constraint, we revealed those combinations of the parameters where the signal from the inflationary induced ALPs domain walls could saturate the amplitude of the NANOGrav excess. The evolution of big enough closed domain walls may incur in formation of wormholes with the walls escaping into baby universes. We studied the conditions, when closed walls escaped into baby universes could leave a detectable imprint in the stochastic gravitational waves background.

After a special kind of complex presentation, the set of amplitude equations was written as a set of nonlinear Dirac equations. For broad-band pulses solitary solutions with half-integer spin and finite energy are found. The solutions correspond to electromagnetic wave with circular Poynting vector and zero divergence. These invisible for detectors waves are called dark states and the localized energy we determine as electromagnetic mass.

Equation of State and Entropy Theory Approach to Thermodynamic Scaling in Polymeric Glass-Forming Liquids
Creators: name: Douglas, Jack F.

Year: 2021
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We show that thermodynamic scaling can be derived by combining the Murnaghan equation of state (EOS) with the generalized entropy theory (GET) of glass formation. In our theory, thermodynamic scaling arises in the non-Arrhenius relaxation regime as a scaling property of the fluid configurational entropy density $s_c$, normalized by its value $s_c^*$ at the onset temperature $T_A$ of glass formation, $s_c / s_c^*$, so that a constant value of $TV^γ$ corresponds to a \textit{reduced isoentropic} fluid condition. Molecular dynamics simulations on a coarse-grained polymer melt are utilized to confirm that the predicted thermodynamic scaling of $τ_α$ by the GET holds both above and below $T_A$ and to test whether the extent $L$ of stringlike collective motion, normalized its value $L_A$ at $T_A$, also obeys thermodynamic scaling, as required for consistency with thermodynamic scaling. While the predicted thermodynamic scaling of both $τ_α$ and $L/ L_A$ is confirmed by simulation, we find that the isothermal compressibility $κ_T$ and the long wavelength limit $S(0)$ of the static structure factor do not exhibit thermodynamic scaling, an observation that would appear to eliminate some proposed models of glass formation emphasizing fluid `structure' over configurational entropy. It is found, however, that by defining a low temperature hyperuniform reference state, we may define a compressibility relative to this condition, $δκ_T$, a transformed dimensionless variable that exhibits thermodynamic scaling and which can be directly related to $s_c / s_c^*$. Further, the Murnaghan EOS allows us to interpret $γ$ as a measure of intrinsic anharmonicity of intermolecular interactions that may be directly determined from the pressure derivative of the material bulk modulus.

description: We investigate the effects to all orders in the Planck length from a generalized un- certainty principle (GUP) on black holes thermodynamics. We calculate the corrected Hawking temperature, entropy, and examine in details the Hawking evaporation process. As a result, the evaporation process is accelerated and the evaporation end-point is a zero entropy, zero heat capacity and finite non zero temperature black hole remnant (BHR). In particular we obtain a drastic reduction of the decay time, in comparison with the results obtained in the Hawking semi classical picture and with the GUP to leading order in the Planck length.

description: Radiative thermal diodes based on two-element structures rectify heat flows thanks to a temperature dependence of material optical properties. The heat transport asymmetry through these systems, however, remains weak without a significant change in material properties with the temperature. Here we explore the heat transport in three-element radiative systems and demonstrate that a strong asymmetry in the thermal conductance can appear because of many-body interactions, without any dependence of optical properties on the temperature. The analysis of transport in three-body systems made with polar dielectrics and metallic layers reveals that rectification coefficients exceeding 50 % can be achieved in the near-field regime with temperature differences of about 200 K. This work paves the way for compact devices to rectify near field radiative heat fluxes over a broad temperature range and could have important applications in the domain of nanoscale thermal management.

description: Moiré superlattices of two-dimensional (2D) materials with a small twist angle are thought to exhibit appreciable flexoelectric effect, though unambiguous confirmation of their flexoelectricity is challenging due to artifacts associated with commonly used piezoresponse force microscopy (PFM). For example, unexpectedly small phase contrast ($\sim$$8^{\circ}$) between opposite flexoelectric polarizations was reported in twisted bilayer graphene (tBG), though theoretically predicted value is $180^{\circ}$. Here we developed a methodology to extract intrinsic moiré flexoelectricity using twisted double bilayer graphene (tDBG) as a model system, probed by lateral PFM. For small twist angle samples, we found that a vectorial decomposition is essential to recover the small intrinsic flexoelectric response at domain walls from a large background signal. The obtained three-fold symmetry of commensurate domains with significant flexoelectric response at domain walls is fully consistent with our theoretical calculations. Incommensurate domains in tDBG with relatively large twist angles can also be observed by this technique. Our work provides a general strategy for unraveling intrinsic flexoelectricity in van der Waals moiré superlattices while providing insights into engineered symmetry breaking in centrosymmetric materials.

Reframing the issue of participation in adult education : an interpretive study
Creators: name: Stalker, Alma Joyce
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation was concerned with why some adults participate in organized adult education activities while others do not. The specific research question was: What are the conceptions of the uses of participation in organized adult education activities held by those in the workplace who have attained a high school diploma or less? A comprehensive review of participation research literature revealed that since the 1920's participation research has been dominated by particular approaches and yielded consistent descriptions of the characteristics of those who participate and those who do not. People's reasonings beneath those findings have remained mainly hidden from researchers, however. In contrast, this research study explored its research question from a different focus, perspective and technique in the hopes of contributing to adult education researchers' understandings of the phenomenon of participation. It focussed on the heterogeneous nature of those who are less likely to participate and used an interpretive perspective and a qualitative technique. Phenomenography was the particular interpretive perspective used in this study. It is a relatively unique research approach developed in Goteborg, Sweden which yields conceptions—that is, categories of description which represent the variations in people's ways of viewing, experiencing or conceptualizing a phenomenon. A pre-tested, open-ended interview collected data about workers' conceptions. A survey-type questionnaire and printed materials about the organization and educational offerings provided additional information. The study identified respondents' conceptions about 1) the context in which the study was conducted (control of workplace opportunities, outcomes of work, impact of technology), 2) opportunities to participate in organized adult education activities and 3) uses of participation in organized adult education activities. In the process, it refined terms, uncovered new dimensions of the issue of participation and challenged traditional assumptions which have guided such research. Insights from this study were integrated into four major areas of relevance to the study of participation in organized adult education activities. These highlighted: 1) the important role of the workplace in forming workers' views of organized adult education activities, 2) the artifical tidiness of the participant/non-participant distinction and 3) three underlying themes which represented workers' focus on the individual, expression of satisfaction and recognition of symbolism. An agenda to direct future adult education research and practice was derived from those themes.
Galaxy bias from forward models: linear and second-order bias of IllustrisTNG galaxies

description: We use field-level forward models of galaxy clustering and the EFT likelihood formalism to study, for the first time for self-consistently simulated galaxies, the relations between the linear $b_1$ and second-order bias parameters $b_2$ and $b_{K^2}$. The forward models utilize all of the information available in the galaxy distribution up to a given order in perturbation theory, which allows us to infer these bias parameters with high signal-to-noise, even from relatively small volumes ($L_{\rm box} = 205{\rm Mpc}/h$). We consider galaxies from the IllustrisTNG simulations, and our main result is that the $b_2(b_1)$ and $b_{K^2}(b_1)$ relations obtained from gravity-only simulations for total mass selected objects are broadly preserved for simulated galaxies selected by stellar mass, star formation rate, color and black hole accretion rate. We also find good agreement between the bias relations of the simulated galaxies and a number of recent estimates for observed galaxy samples. The consistency under different galaxy selection criteria suggests that theoretical priors on these bias relations may be used to improve cosmological constraints based on observed galaxy samples. We do identify some small differences between the bias relations in the hydrodynamical and gravity-only simulations, which we show can be linked to the environmental dependence of the relation between galaxy properties and mass. We also show that the EFT likelihood recovers the value of $σ_8$ to percent-level from various galaxy samples (including splits by color and star formation rate) and after marginalizing over 8 bias parameters. This demonstration using simulated galaxies adds to previous works based on halos as tracers, and strengthens further the potential of forward models to infer cosmology from galaxy data.

description: Metastasis is still one of the main obstacles in the treatment of breast cancer. This study aimed to develop disulfiram (DSF) and doxorubicin (DOX) co-loaded nanoparticles (DSF-DOX NPs) with enzyme/pH dual stimuli-responsive characteristics to inhibit breast cancer metastasis. DSF-DOX NPs were prepared using the amphiphilic poly(ε-caprolactone)-b-poly(L-glutamic acid)-g-methoxy poly(ethylene glycol) (PCL-b-PGlu-g-mPEG) copolymer by a classical dialysis method. In vitro release tests, in vitro cytotoxicity assay, and anti-metastasis studies were conducted to evaluate pH/enzyme sensitivity and therapeutic effect of DSF-DOX NPs. The specific pH and enzyme stimuli-responsiveness of DSF-DO NPs can be attributed to the transformation of secondary structure and the degradation of amide bonds in the PGlu segment, respectively. This accelerated drug release significantly increased the cytotoxicity to 4T1 cells. Compared with the control group, the DSF-DOX NPs showed a strong inhibition of in vitro metastasis with a wound healing rate of 36.50% and a migration rate of 18.39%. Impressively, in vivo anti-metastasis results indicated that the metastasis of 4T1 cells was almost completely suppressed by DSF-DOX NPs. DSF-DOX NPs with controllable tumor site delivery of DOX and DSF were a prospectively potential strategy for metastatic breast cancer treatment.

description: Pair production in inhomogeneous electric fields with symmetrical frequency chirp is studied numerically using the Dirac-Heisenberg-Wigner formalism. We investigate high- and low-frequency modes and consider two carrier envelope phases. Momentum spectrum is sensitive to chirp causing different interference effect for different spatial scales as well as the carrier phase of the external field. The reduced particle number is in general enhanced with increasing chirp. The effect of spatial scale of the field on the reduced particle number is also examined. It is found that it is enhanced at small spatial scale but is almost unchangeable at large spatial scales for the considered field parameters. On the other hand, at small spatial scale, the reduced particle number is enhanced by one or two orders when chirp is applied with the exception of cosine low-frequency field which is only a few times larger. Moreover it is found that the reduced particle number is further increased by symmetrical chirp at about two times by comparing to the usual asymmetrical chirp in high frequency field.

The first application detects anomalous performance and finds its root cause of faults, configuration, or network procedure failures. The second application uses clustering to learn the relationship between two performance measures. Our proposed applications run in near-constant time complexity, making them, combined with subject-matter expertise validation, suitable real-time RIC applications for network diagnosis.

description: C’est suite à un cours qui a été donné lors de notre formation que nous nous sommes intéressées et questionnées sur l’importance de la motivation chez les élèves. Suite à la réalisation de notre cadre théorique, nous avons pu déduire que la motivation joue un rôle important dans l’apprentissage et les performances scolaires des élèves. Ces derniers doivent être motivés pour qu’ils puissent acquérir des savoirs et réussir à l’école. Nous retenons donc que l’apprentissage est difficilement réalisable, voire impossible, pour un élève qui n’est pas motivé. Tout enseignant devrait alors avoir pour but de motiver les élèves pour les amener à améliorer leurs performances scolaires. Le présent mémoire se penche sur l’efficacité de deux stratégies d’intervention sur la motivation des élèves (Viau, 1994) testées dans le cadre de notre stage. Ainsi, nous voulons vérifier l’efficacité d’une approche pédagogique qui est l’enseignement explicite puis voir l’influence qu’elle peut avoir sur les performances (en mathématiques) et sur la motivation des élèves de 8ème HarmoS. Parallèlement à cela, nous intervenons avec des échanges guidés qui visent à modifier les attributions causales des élèves dans le cas où, initialement, elles sont néfastes à l’ apprentissage. Ainsi, nous cherchons à mettre en évidence l’influence que ces deux interventions ont sur les performances, la perception de contrôlabilité et la motivation des élèves. Cette évolution peut se faire à trois niveaux, c’est-à-dire qu’il pourra s’agir d’une évolution positive, d’une stagnation ou encore d’une évolution négative. Les résultats de notre recherche seront d’abord présentés dans une analyse comprenant sept profils d’élèves, puis dans une deuxième analyse générale, illustrée par trois graphiques en secteurs.

description: Measurement-based quantum computation has emerged from the physics community as a new approach to quantum computation where the notion of measurement is the main driving force of computation. This is in contrast with the more traditional circuit model which is based on unitary operations. Among measurement-based quantum computation methods, the recently introduced one-way quantum computer stands out as fundamental. We develop a rigorous mathematical model underlying the one-way quantum computer and present a concrete syntax and operational semantics for programs, which we call patterns, and an algebra of these patterns derived from a denotational semantics. More importantly, we present a calculus for reasoning locally and compositionally about these patterns. We present a rewrite theory and prove a general standardization theorem which allows all patterns to be put in a semantically equivalent standard form. Standardization has far-reaching consequences: a new physical architecture based on performing all the entanglement in the beginning, parallelization by exposing the dependency structure of measurements and expressiveness theorems. Furthermore we formalize several other measurement-based models: Teleportation, Phase and Pauli models and present compositional embeddings of them into and from the one-way model. This allows us to transfer all the theory we develop for the one-way model to these models. This shows that the framework we have developed has a general impact on measurement-based computation and is not just particular to the one-way quantum computer.

description: We have measured highly visible Aharonov-Bohm (AB) oscillations in a ring structure defined by local anodic oxidation on a p-type GaAs heterostructure with strong spin-orbit interactions. Clear beating patterns observed in the raw data can be interpreted in terms of a spin geometric phase. Besides h/e oscillations, we resolve the contributions from the second harmonic of AB oscillations and also find a beating in these h/2e oscillations. A resistance minimum at B=0T, present in all gate configurations, is the signature of destructive interference of the spins propagating along time-reversed paths.

description: We describe a new ring laser with area A = 833 m^2 and update performance statistics for several such machines. Anandan & Chaio 1982 judged ring lasers inferior to matter interferometers as possible detectors of gravitational waves. However, we note that geophysically interesting results have been obtained from large ring lasers and that there is still a lot of room for improvements.

description: Escalator-related injuries threaten public health with the widespread use of escalators. The existing studies tend to focus on after-the-fact statistics, reflecting on the original design and use of defects to reduce the impact of escalator-related injuries, but few attention has been paid to ongoing and impending injuries. In this study, a multi-module escalator safety monitoring system based on computer vision is designed and proposed to simultaneously monitor and deal with three major injury triggers, including losing balance, not holding on to handrails and carrying large items. The escalator identification module is utilized to determine the escalator region, namely the region of interest. The passenger monitoring module is leveraged to estimate the passengers' pose to recognize unsafe behaviors on the escalator. The dangerous object detection module detects large items that may enter the escalator and raises alarms. The processing results of the above three modules are summarized in the safety assessment module as the basis for the intelligent decision of the system. The experimental results demonstrate that the proposed system has good performance and great application potential.
description: Please excuse me for taking some of your time. But that we have not yet studied our work completely and some new great results are discovered. So after carefully thinking, we are going to rearrange this manuscript and try to give more precise model. Thus, we decided to withdraw this manuscript with great pity
