description: We investigate the dark matter and the cosmological baryon asymmetry in a simple theory where baryon (B) and lepton (L) number are local gauge symmetries that are spontaneously broken. In this model, the cold dark matter candidate is the lightest new field with baryon number and its stability is an automatic consequence of the gauge symmetry. Dark matter annihilation is either through a leptophobic gauge boson whose mass must be below a TeV or through the Higgs boson. Since the mass of the leptophobic gauge boson has to be below the TeV scale one finds that in the first scenario there is a lower bound on the elastic cross section of about 5x10^{-46} cm^2. Even though baryon number is gauged and not spontaneously broken until the weak scale, a cosmologically acceptable baryon excess is possible. There is tension between achieving both the measured baryon excess and the dark matter density.

description: This paper studies the problem of massive Internet of things (IoT) access in beyond fifth generation (B5G) networks using non-orthogonal multiple access (NOMA) technique. The problem involves massive IoT devices grouping and power allocation in order to respect the low latency as well as the limited operating energy of the IoT devices. The considered objective function, maximizing the number of successfully received IoT packets, is different from the classical sum-rate-related objective functions. The problem is first divided into multiple NOMA grouping subproblems. Then, using competitive analysis, an efficient online competitive algorithm (CA) is proposed to solve each subproblem. Next, to solve the power allocation problem, we propose a new reinforcement learning (RL) framework in which a RL agent learns to use the CA as a black box and combines the obtained solutions to each subproblem to determine the power allocation for each NOMA group. Our simulations results reveal that the proposed innovative RL framework outperforms deep-Q-learning methods and is close-to-optimal.

Nuclear Star Clusters from Clustered Star Formation

description: Photometrically distinct nuclear star clusters (NSCs) are common in late-type-disk and spheroidal galaxies. The formation of NSCs is inevitable in the context of normal star formation in which a majority of stars form in clusters. A young, mass-losing cluster embedded in an isolated star-forming galaxy remains gravitationally bound over a period determined by its initial mass and the galactic tidal field. The cluster migrates radially toward the center of the galaxy and becomes integrated in the NSC if it reaches the center. The rate at which the NSC grows by accreting young clusters can be estimated from empirical cluster formation rates and dissolution times. We model cluster migration and dissolution and find that the NSCs in late-type disks and in spheroidals could have assembled from migrating clusters. The resulting stellar nucleus contains a small fraction of the stellar mass of the galaxy; this fraction is sensitive to the high-mass truncation of the initial cluster mass function (ICMF). The resulting NSC masses are consistent with the observed values, but generically, the final NSCs are surrounded by a spatially more extended excess over the inward-extrapolated exponential (or Sersic) law of the outer galaxy. We suggest that the excess can be related to the pseudobulge phenomenon in disks, though not all of the pseudobulge mass assembles this way. Comparison with observed NSC masses can be used to constrain the truncation mass scale of the ICMF and the fraction of clusters suffering prompt dissolution. We infer truncation mass scales of ~ 10^5 M_sun) without (with 90%) prompt dissolution.
description: 11 pages, 12 figures, revised version corrects a numerical error that lead to a moderate overestimate of NSC masses; conclusions remain unchanged

description: We present a combined experimental and theoretical study on the rotationally inelastic scattering of OH ($X\,^2Π_{3/2}, J=3/2, f$) radicals with the collision partners He, Ne, Ar, Kr, Xe, and D$_2$ as a function of the collision energy between $\sim 70$ cm$^{-1}$ and 400~cm$^{-1}$. The OH radicals are state selected and velocity tuned prior to the collision using a Stark decelerator, and field-free parity-resolved state-to-state inelastic relative scattering cross sections are measured in a crossed molecular beam configuration. For all OH-rare gas atom systems excellent agreement is obtained with the cross sections predicted by close-coupling scattering calculations based on accurate \emph{ab initio} potential energy surfaces. This series of experiments complements recent studies on the scattering of OH radicals with Xe [Gilijamse \emph{et al.}, Science {\bf 313}, 1617 (2006)], Ar [Scharfenberg \emph{et al.}, Phys. Chem. Chem. Phys. {\bf 12}, 10660 (2010)], He, and D$_2$ [Kirste \emph{et al.}, Phys. Rev. A {\bf 82}, 042717 (2010)]. A comparison of the relative scattering cross sections for this set of collision partners reveals interesting trends in the scattering behavior.

description: Starting with a 5D physical vacuum described by a 5D Ricci-flat background metric, we study the emergence of gravitational waves (GW) from the Induce Matter (IM) theory of gravity. We obtain the equation of motion for GW on an 4D curved spacetime which has the form of a Fierz-Pauli one. In our model the mass of gravitons $m_g$ is induced by a static foliation on the noncompact space-like extra dimension and the source-term is originated in the interaction of the GW with the induced connections of the background 5D metric. Here, relies the main difference of this formalism with the original Fierz-Pauli one.

Quantumness of correlations and entanglement

description: Generalized measurement schemes on one part of bipartite states, which would leave the set of all separable states insensitive are explored here to understand quantumness of correlations in a more general perspecitve. This is done by employing linear maps associated with generalized projective measurements. A generalized measurement corresponds to a quantum operation mapping a density matrix to another density matrix, preserving its positivity, hermiticity and traceclass. The Positive Operator Valued Measure (POVM) -- employed earlier in the literature to optimize the measures of classical/quatnum correlations -- correspond to completely positive (CP) maps. The other class, the not completely positive (NCP) maps, are investigated here, in the context of measurements, for the first time. It is shown that that such NCP projective maps provide a new clue to the understanding the quantumness of correlations in a general setting. Especially, the separability-classicality dichotomy gets resolved only when both the classes of projective maps (CP and NCP) are incorporated as optimizing measurements. An explicit example of a separable state -- exhibiting non-zero quantumn discord when possible optimizing measurements are restricted to POVMs -- is re-examined with this extended scheme incorporating NCP projective maps to elucidate the power of this approach.

Assessing the reliability of sedimentary Nd isotopic composition to reconstruct past changes in deep water mass distribution
Creators: name: Patton, Genevieve
Publisher: name: University of British Columbia
Year: 2019

description: To better understand how our climate will change in the future, we look to past analogues of our current climate and rely on indicators of past fluctuations preserved in marine sediment. One such indicator is the isotopic composition of neodymium preserved in authigenic phases of marine sediment, which has been widely applied to reconstruct water mass distribution through time. However, recent studies have suggested that the Nd isotopic composition of authigenic phases associated with foraminifera and bulk marine sediment is influenced by early diagenesis. This dissertation documents through experiments and numerical modelling that the Nd isotopic composition of these authigenic phases is influenced by Nd released to pore water through lithogenic dissolution. To identify the source of Nd to a synthetic authigenic phase, we use an incubation of sediment and seawater from the local Strait of Georgia. By tagging the seawater with a unique isotopic ratio, we show that pore water primarily determines the Nd isotopic composition of the authigenic phase. Then, we examine core top sediment in the Labrador Sea, which acts as a natural analogue of the incubation experiment. The seawater in the region has a more radiogenic Nd isotopic composition than the sediment which fills the basin, providing two natural end members. Measurements of the Nd isotopic composition of foraminifera and the authigenic phase associated with bulk sediment are significantly more unradiogenic than seawater. These measurements indicate that seawater is not the primary source of Nd to the authigenic phases in this region. By constructing a numerical model of Nd concentration and isotopic composition in pore water, we are able to quantify diagenetic Nd added to authigenic phases and apply this numerical model to a location in the Equatorial Atlantic Ocean. The diagenetic biases that shift the ℇNd of foraminiferal records in this region mimic the expected variations in ocean circulation. While the authigenic phase associated with foraminifera and bulk sediment leachates seems to preserve the ℇNd of modern seawater, this proxy is subject to effects of diagenesis that change in time, and therefore we conclude that it is not a reliable recorder of ocean circulation.

description: Excitonic insulators host a condensate of electron-hole pairs at equilibrium, giving rise to collective many-body effects. Although several materials have emerged as excitonic insulator candidates, evidence of long-range coherence is lacking and the origin of the ordered phase in these systems remains controversial. Here, using ultrafast pump-probe microscopy, we investigate the possible excitonic insulator Ta2NiSe5 Below 328 K, we observe the anomalous micrometer-scale propagation of coherent modes at velocities of ~105 m/s, which we attribute to the hybridization between phonon modes and the phase mode of the condensate. We develop a theoretical framework to support this explanation and propose that electronic interactions provide a substantial contribution to the ordered phase in Ta2NiSe5 These results allow us to understand how the condensate's collective modes transport energy and interact with other degrees of freedom. Our study provides a unique paradigm for the investigation and manipulation of these properties in strongly correlated materials.

description: We study one-dimensional general non-Hermitian models with asymmetric long-range hopping and explore to analytically solve the systems under some specific boundary conditions. Although the introduction of long-range hopping terms prevents us from finding analytical solutions for arbitrary boundary parameters, we identify the existence of exact solutions when the boundary parameters fulfill some constraint relations, which give the specific boundary conditions. Our analytical results show that the wave functions take simple forms and are independent of hopping range, while the eigenvalue spectra display rich model-dependent structures. Particularly, we find the existence of a special point coined as pseudo-periodic boundary condition, for which the eigenvalues are the same as the periodical system when the hopping parameters fulfill certain conditions, whereas eigenstates display non-Hermitian skin effect.

The MgII Cross-section of Luminous Red Galaxies

description: We describe a search for MgII(2796,2803) absorption lines in Sloan Digital Sky Survey (SDSS) spectra of QSOs whose lines of sight pass within impact parameters of 200 kpc of galaxies with photometric redshifts of z=0.46-0.6 and redshift errors Delta z~0.05. The galaxies selected have the same colors and luminosities as the Luminous Red Galaxy (LRG) population previously selected from the SDSS. A search for Mg II lines within a redshift interval of +/-0.1 of a galaxy's photometric redshift shows that absorption by these galaxies is rare: the covering fraction is ~ 10-15% between 20 and 100 kpc, for Mg II lines with rest equivalent widths of Wr >= 0.6Å, falling to zero at larger separations. There is no evidence that Wr correlates with impact parameter or galaxy luminosity. Our results are consistent with existing scenarios in which cool Mg II-absorbing clouds may be absent near LRGs because of the environment of the galaxies: if LRGs reside in high-mass groups and clusters, either their halos are too hot to retain or accrete cool gas, or the galaxies themselves - which have passively-evolving old stellar populations - do not produce the rates of star formation and outflows of gas necessary to fill their halos with Mg II absorbing clouds. In the rarer cases where Mg II is detected, however, the origin of the absorption is less clear. Absorption may arise from the little cool gas able to reach into cluster halos from the intergalactic medium, or from the few star-forming and/or AGN-like LRGs that are known to exist.

description: A feature of this NPP project is the use of a single-case steam generator. This makes it possible to reduce the metal consumption of the structure in comparison with the sectional-modular steam generator, which is currently used with reactor plants of the BN type. Based on the results of the special task of âModeling of processes in the BN-1200 steam generatorâ, it is concluded that it is inappropriate to use an elongated branch pipe in the coolant supply unit.
Predicting health outcomes and sale price of male dairy calves undergoing long distance transportation
Creators: name: Wilson, Devon
Publisher: name: University of British Columbia

description: Male dairy calves are often marketed at a young age when they are vulnerable to health and welfare problems. This study described the condition of male dairy calves before transportation and evaluated factors associated with selling price at an auction market and health outcomes at two calf-rearing facilities (calf growers). Male calves were evaluated at their dairy farm of origin, at an auction market, and after long-distance transportation to a calf grower. Measures of calf condition included a standardized health examination, age, heart girth circumference (HG), and serum total protein as an indication of failure of transfer of passive immunity (FTPI). Selling price at the auction, and treatments for diarrhea or bovine respiratory disease (BRD), along with all mortalities, were recorded during the first 2 wk after arrival at a calf grower. A McNemar Test was used to determine if health deteriorated after transportation and regression analysis was used to evaluate the effects of calf condition on selling price and health outcomes. Large variation in calf condition before transportation was found among dairy farms, with a median prevalence of 17% diarrhea, 2% BRD, 9% navel disease, and 12% FTPI. Calves were transported at a median (interquartile range) age of 5 (3-7) d, with a mean ± SD heart girth circumference of 82 ± 4 cm. Calves observed at auction market with beef genetics that had a large HG and bright, alert attitude sold for a higher price. Immediately after transportation to the calf grower, a greater proportion of calves had an elevated body temperature and a lower proportion had diarrhea, possibly due to dehydration. Calves with FTPI were more likely to develop a depressed attitude after transportation. In the first 2 wk after arrival, 23% of calves were treated for diarrhea, 44% were treated for BRD, and 3.9% died. Important risk factors for diarrhea treatment included small HG and navel disease, and calves with a depressed attitude were more likely to die. These findings indicate there is a need for improvement in the condition of male dairy calves to protect their health and welfare and increase their economic value.

description: In response to the challenges of data mining, discriminant analysis continues to evolve as a vital branch of statistics. Our recently introduced method of vertex discriminant analysis (VDA) is ideally suited to handle multiple categories and an excess of predictors over training cases. The current paper explores an elaboration of VDA that conducts classification and variable selection simultaneously. Adding lasso ($\ell_1$-norm) and Euclidean penalties to the VDA loss function eliminates unnecessary predictors. Lasso penalties apply to each predictor coefficient separately; Euclidean penalties group the collective coefficients of a single predictor. With these penalties in place, cyclic coordinate descent accelerates estimation of all coefficients. Our tests on simulated and benchmark real data demonstrate the virtues of penalized VDA in model building and prediction in high-dimensional settings.

Sub-kilometre scale ionospheric studies at the SKA-Low site, using MWA extended baselines

description: The ambitious scientific goals of SKA require a matching capability for calibration of instrumental and atmospheric propagation contributions as functions of time, frequency and position. The development of novel calibration algorithms to meet these requirements is an active field of research. In this work {we aim to characterize} these, focusing on the spatial and temporal structure scales of the ionospheric effects; ultimately, these provide the guidelines for designing the optimum calibration strategy. We used empirical ionospheric measurements at the site where the SKA-Low will be built, using MWA Phase-2 Extended baseline observations and the station-based Low-frequency Excision of Atmosphere in Parallel (LEAP) calibration algorithm. We have done this via direct regression analysis of the ionospheric screens and by forming the full and detrended structure functions. We found that 50% of the screens show significant non-linear structures at scales >0.6km that dominate at >2km, and 1% show significant sub-minute temporal changes, providing that there is sufficient sensitivity. Even at the moderate sensitivity and baseline lengths of MWA, non-linear corrections are required at 88 MHz during moderate-weather and at 154 MHz during poor weather, or for high SNR measurements. Therefore we predict that improvements will come from correcting for higher-order defocusing effects in observations with MWA Phase-2, and further with new developments in MWA Phase-3. Because of the giant leap in sensitivity, the correction for complex ionospheric structures will be mandatory on SKA-Low, for both imaging and tied-array beam formation.

description: This article presents a compositional method based on Algorithmic Sound Identities, capable of developing an active and dynamic musical thought process.

We will refer to this method as AICS (Algorithmic Identity Composition System). Contemporary computing technology provides the capability to gather and process vast amounts of real-time data, which can be leveraged to construct dynamically evolving algorithms. To make this model applicable, we take inspiration from human language, which serves as an acquired method for learning and expressing thought in its three fundamental components: Semiotics, Syntax, and Semantics. Semiotics pertains to the study of signs and symbols as elements of communication and is crucial for understanding how sounds can be symbolically used within a musical system. This complex aspect, which also involves notational writing, is beyond the scope of this manuscript and will be

addressed in future work.Syntax refers to the structure and rules that govern the combination of sound elements, similarly to how words combine to form sentences in spoken language. Algorithmic Sound Identities syntactically determine a behavioral model that we will call Sound Personality. Finally, Semantics deals with the meaning and interpretation of these elements within the musical context, analyzing how sounds convey meaning and emotions. This is the aspect tied to the imagination of the composer and represents the abstract depiction of the Sound Personality.This approach allows the structuring of a sonic work capable of evolving autonomously through interaction with data from reality.

description: We theoretically analyze the effectiveness of multiple-pulse laser alignment methods for asymmetric-top molecules. As an example, we choose SO_2 and investigate the alignment dynamics induced by two different sequences, each consisting of four identical laser pulses. Each sequence differs only in the time delay between the pulses. Equally spaced pulses matching the alignment revival of the symmetrized SO_2 rotor model are exploited in the first sequence. The pulse separations in the second sequence are short compared to the rotation dynamics of the molecule and monotonically increase the degree of alignment until the maximum alignment is reached. We point out the significant differences between the alignment dynamics of SO_2 treated as an asymmetric-top and a symmetric-top rotor, respectively. We also explain why the fast sequence of laser pulses creates considerably stronger one-dimensional molecular alignment for asymmetric-top molecules. In addition, we show that multiple-pulse trains with elliptically polarized pulses do not enhance one-dimensional alignment or create three-dimensional alignment.

description: As an "input" state of a linear (Mach-Zehnder or Ramsey) interferometer, the phase-squeezed state proposed by Berry and Wiseman exhibits the best sensitivity approaching to the Heisenberg limit [Phys. Rev. Lett. 85, 5098 (2000)]. In this paper, we find that it can be generated dynamically with atomic Bose-Einstein condensates confined in a symmetric double well. Similar with the Berry and Wiseman's state, the prepared states show the squeezing along spin operator S_y and the anti-squeezing along S_z, leading to a sub-shot-noise of the phase sensitivity.

description: This study aims to compare the alignment of Large Language Models such as OpenAI's ChatGPT, Google DeepMind’s Gemini, and Anthropic’s Claude with human reviewers in assessing clinical practice guidelines (CPGs) using the AGREE II instrument. The AGREE II tool is widely used to assess these guidelines across six domains, but there is limited research on how effectively LLMs can replicate human assessments in this context. By assessing the alignment of LLM-generated scores with those of trained human appraisers, this study seeks to explore whether LLMs can serve as a useful tool in pre-screening CPGs, flagging areas requiring further human attention. The potential of LLMs to streamline and augment the guideline evaluation process could be particularly impactful in fields where frequent updates to CPGs are necessary. We will extract CPGs from a dedicated repository of systematic reviews according to the eligibility criteria. LLMs will assess these guidelines based on customized prompts, with output analyzed for agreement with human reviewers. We will employ Bland Altman analysis to measure agreement for each of the six AGREE II domains, as well as an overall domain score. Through these plots, we will determine the mean differences, observe the distribution of differences to evaluate the scoring profile of LLMs relative to humans. We will report findings according to the Guidelines for Reporting Reliability and Agreement Studies (GRRAS) checklist.

description: System-scale magnetohydrodynamic (MHD) waves within Earth's magnetosphere are often understood theoretically using box models. While these have been highly instructive in understanding many fundamental features of the various wave modes present, they neglect the complexities of geospace such as the inhomogeneities and curvilinear geometries present. Here we show global MHD simulations of resonant waves impulsively-excited by a solar wind pressure pulse. Although many aspects of the surface, fast magnetosonic (cavity/waveguide), and Alfvén modes present agree with the box and axially symmetric dipole models, we find some predictions for large-scale waves are significantly altered in a realistic magnetosphere. The radial ordering of fast mode turning points and Alfvén resonant locations may be reversed even with monotonic wave speeds. Additional nodes along field lines that are not present in the displacement/velocity occur in both the perpendicular and compressional components of the magnetic field. Close to the magnetopause the perpendicular oscillations of the magnetic field have the opposite handedness to the velocity. Finally, widely-used detection techniques for standing waves, both across and along the field, can fail to identify their presence. We explain how all these features arise from the MHD equations when accounting for a non-uniform background field and propose modified methods which might be applied to spacecraft observations.
