Linear transfers, Kantorovich operators, and their ergodic properties
Creators: name: Bowles, Malcolm
Publisher: name: University of British Columbia
Year: 2020

description: In this work, we introduce and study a class of convex functionals on pairs of probability measures, the linear transfers, which have a structure that com- monly arises in the dual formulations of many well-studied variational prob- lems. We show that examples of linear transfers include a large number of well-known transport problems, including the weak, stochastic, martingale, and cost-minimising transports. Further examples include the balayage of measures, and ergodic optimisation of expanding dynamical systems, among others. We also introduce an extension of the linear transfers, the convex transfers, and show that they include the relative entropy functional and p-powers (p ≥ 1) of linear transfers. We study the properties of linear and convex transfers and show that the inf-convolution operation preserves their structure. This allows dual formu- lations of transport-entropy and other related inequalities, to be computed in a systematic fashion. Motivated by connections of optimal transport to the theory of Aubry- Mather and weak KAM for Hamiltonian systems, we develop an analog in the setting of linear transfers. We prove the existence of an idempotent operator which maps into the set of weak KAM solutions, an idempotent linear transfer that plays the role of the Peierls barrier, and we identify analogous objects in this setting such as the Mather measures and the Aubry set. We apply this to the framework of ergodic optimisation in the holonomic case.

description: The adiabatic approximation in time-dependent density functional theory (TDDFT) yields reliable excitation spectra with great efficiency in many cases, but fundamentally fails for states of double excitation character. We discuss how double-excitations are at the root of some of the most challenging problems for TDDFT today. We then present new results for (i) the calculation of autoionizing resonances in the helium atom, (ii) understanding the nature of the double excitations appearing in the quadratic response function, and (iii) retrieving double-excitations through a real-time semiclassical approach to correlation in a model quantum dot.
Effects of Multisensory Stop Signals on Sensitivity to Alcohol-Induced Disinhibition in Drinkers with ADHD

description: Abstract:
Multisensory environments facilitate behavioral functioning in humans. The redundant signal effect (RSE) refers to the observation that individuals respond more quickly to stimuli when information is presented as multisensory, redundant stimuli rather than as a single stimulus presented to either modality alone. Our studies show that the disinhibiting effects of alcohol are attenuated when stop signals are multisensory versus unisensory. The present study expanded on this research to test the degree to which multisensory stop signals could also attenuate the disinhibiting effects of alcohol in those with attention-deficit hyperactivity disorder (ADHD), a clinical population characterized by poor impulse control. The study compared young adults with ADHD with healthy controls and examined the acute impairing effect of alcohol on response inhibition to stop signals that were presented as a unisensory stimulus or a multisensory stimulus. For controls, results showed alcohol impaired response inhibition to unisensory stop signals but not to multisensory stop signals. Response inhibition of those with ADHD was impaired by alcohol regardless of whether stop signals were unisensory or multisensory. The failure of multisensory stimuli to attenuate alcohol impairment in those with ADHD highlights a specific vulnerability that could account for heightened sensitivity to the disruptive effects of alcohol.

description: The main function of IDS (Intrusion Detection System) is to protect the system, analyze and predict the behaviors of users. Then these behaviors will be considered an attack or a normal behavior. Though IDS has been developed for many years, the large number of return alert messages makes managers maintain system inefficiently. In this paper, we use RST (Rough Set Theory) and SVM (Support Vector Machine) to detect intrusions. First, RST is used to preprocess the data and reduce the dimensions. Next, the features were selected by RST will be sent to SVM model to learn and test respectively. The method is effective to decrease the space density of data. The experiments will compare the results with different methods and show RST and SVM schema could improve the false positive rate and accuracy.

description: Solubility enhancement of poorly soluble active pharmaceutical ingredients is of crucial importance for drug development and processing. Extensive experimental screening is limited due to the vast number of potential solvent combinations. Hence, theoretical models can offer valuable hints for guiding experiments aimed at providing solubility data. In this paper, we explore the possibility of applying quantum-chemistry-derived molecular descriptors, adequate for development of an ensemble of neural networks model (ENNM), for solubility computations of sulfamethizole (SMT) in neat and aqueous binary solvent mixtures. The machine learning procedure utilized information encoded in σ-potential profiles computed using the COSMO-RS approach. The resulting nonlinear model is accurate in backcomputing SMT solubility and allowed for extensive screening of green solvents. Since the experimental characteristics of SMT solubility are limited, the data pool was extended by new solubility measurements in water, five neat organic solvents (acetonitrile, N,N-dimethylformamide, dimethyl sulfoxide, 1,4-dioxane, and methanol), and their aqueous binary mixtures at 298.15, 303.15, 308.15, and 313.15 K. Experimentally determined order of decreasing SMT solubility in neat solvents is the following: N,N-dimethylformamide > dimethyl sulfoxide > methanol > acetonitrile > 1,4dioxane >> water, in all studied temperatures. Similar trends are observed for aqueous binary mixtures. Since N,N-dimethylformamide is not considered as a green solvent, the more acceptable replacers were searched for using the developed model. This step led to the conclusion that 4-formylmorpholine is a real alternative to N,N-dimethylformamide, fulfilling all requirements of both high dissolution potential and environmental friendliness.
The parametric g-formula to estimate the effect of highly active antiretroviral therapy on incident AIDS or death

description: The parametric g-formula can be used to contrast the distribution of potential outcomes under arbitrary treatment regimes. Like g-estimation of structural nested models and inverse probability weighting of marginal structural models, the parametric g-formula can appropriately adjust for measured time-varying confounders that are affected by prior treatment. However, there have been few implementations of the parametric g-formula to date. Here, we apply the parametric g-formula to assess the impact of highly active antiretroviral therapy on time to acquired immune deficiency syndrome (AIDS) or death in two US-based human immunodeficiency virus cohorts including 1498 participants. These participants contributed approximately 7300 person-years of follow-up (49% exposed to highly active antiretroviral therapy) during which 382 events occurred and 259 participants were censored because of dropout. Using the parametric g-formula, we estimated that antiretroviral therapy substantially reduces the hazard of AIDS or death (hazard ratio=0.55; 95% confidence limits [CL]: 0.42, 0.71). This estimate was similar to one previously reported using a marginal structural model, 0.54 (95% CL: 0.38, 0.78). The 6.5-year difference in risk of AIDS or death was 13% (95% CL: 8%, 18%). Results were robust to assumptions about temporal ordering, and extent of history modeled, for time-varying covariates. The parametric g-formula is a viable alternative to inverse probability weighting of marginal structural models and g-estimation of structural nested models for the analysis of complex longitudinal data.

description: Interference alignment (IA) is a joint-transmission technique that achieves the capacity of the interference channel for high signal-to-noise ratios (SNRs). Most prior work on IA is based on the impractical assumption that perfect and global channel-state information(CSI) is available at all transmitters. To implement IA, each receiver has to feed back CSI to all interferers, resulting in overwhelming feedback overhead. In particular, the sum feedback rate of each receiver scales quadratically with the number of users even if the quantized CSI is fed back. To substantially suppress feedback overhead, this paper focuses on designing efficient arrangements of feedback links, called feedback topologies, under the IA constraint. For the multiple-input-multiple-output (MIMO) K-user interference channel, we propose the feedback topology that supports sequential CSI exchange (feedback and feedforward) between transmitters and receivers so as to achieve IA progressively. This feedback topology is shown to reduce the network feedback overhead from a cubic function of K to a linear one. To reduce the delay in the sequential CSI exchange, an alternative feedback topology is designed for supporting two-hop feedback via a control station, which also achieves the linear feedback scaling with K. Next, given the proposed feedback topologies, the feedback-bit allocation algorithm is designed for allocating feedback bits by each receiver to different feedback links so as to regulate the residual interference caused by the finite-rate feedback. Simulation results demonstrate that the proposed bit allocation leads to significant throughput gains especially in strong interference environments.

description: We report the fabrication of Ge:Mn ferromagnetic semiconductors by Mn-ion implantation into Ge followed by pulsed laser annealing. Benefiting from the short time annealing, the hole concentration in Mn-implanted Ge has been increased by two orders of magnitude from 10$^{18}$ to over 10$^{20}$ cm$^{-3}$. Likely due to the high hole concentration, we observe that the longitudinal and Hall resistances exhibit the same hysteresis as the magnetization, which is usually considered as a sign of carrier-mediated ferromagnetism.

description: We extend the Minimum Supersymmetry Standard Model by a non-anomalous family (NAF) U(1)'_{NAF} gauge symmetry. All gauge anomalies are cancelled with no additional exotics other than the three right-handed neutrinos. The FI D-terms associated with the U(1)'_{NAF} symmetry lead to additional positive contributions to slepton squared masses. In a RG invariant way, this thus solves the tachyonic slepton mass problem in Anomaly Mediated Supersymmetry Breaking. In addition, the U (1)'_{NAF} symmetry naturally gives rise to the fermion mass hierarchy and mixing angles, and determines the mass spectrum of the sparticles.

Lower-Luminosity Galaxies could reionize the Universe: Very Steep Faint-End Slopes to the UV Luminosity Functions at z>=5-8 from the HUDF09 WFC3/IR Observations

description: The HUDF09 data are the deepest near-IR observations ever, reaching to 29.5 mag. Luminosity functions (LF) from these new HUDF09 data for 132 z\sim7 and z\sim8 galaxies are combined with new LFs for z\sim5-6 galaxies and the earlier z\sim4 LF to reach to very faint limits (<0.05 L*(z=3)). The faint-end slopes alpha are steep: -1.79+/-0.12 (z\sim5), -1.73+/-0.20 (z\sim6), -2.01+/-0.21 (z\sim7), and -1.91+/-0.32 (z\sim8). Slopes alpha\lesssim-2 lead to formally divergent UV fluxes, though galaxies are not expected to form below \sim-10 AB mag. These results have important implications for reionization. The weighted mean slope at z\sim6-8 is -1.87+/-0.13. For such steep slopes, and a faint-end limit of -10 AB mag, galaxies provide a very large UV ionizing photon flux. While current results show that galaxies can reionize the universe by z\sim6, matching the Thomson optical depths is more challenging. Extrapolating the current LF evolution to z>8, taking alpha to be -1.87+/-0.13 (the mean value at z\sim6-8), and adopting typical parameters, we derive Thomson optical depths of 0.061_{-0.006}^{+0.009}. However, this result will change if the faint-end slope alpha is not constant with redshift. We test this hypothesis and find a weak, though uncertain, trend to steeper slopes at earlier times (dalpha/dz\sim-0.05+/-0.04), that would increase the Thomson optical depths to 0.079_{-0.017}^{+0.063}, consistent with recent WMAP estimates (tau=0.088+/-0.015). It may thus not be necessary to resort to extreme assumptions about the escape fraction or clumping factor. Nevertheless, the uncertainties remain large. Deeper WFC3/IR+ACS observations can further constrain the ionizing flux from galaxies.

Exploring the importance of sediment disconnectivity and connectivity in glacierized catchments, Tahoma Creek, WA
Creators: name: Turley, Michael
Publisher: name: University of British Columbia
Year: 2020

description: In recent decades, connectivity has emerged as a prominent topic of discussion within the geomorphology community but lacks consensus around a general definition. On the other hand, disconnectivity is often an afterthought even though it is prevalent at most spatiotemporal scales. In response, we suggest defining disconnectivity as the dominant but inefficient state of the system in transferring matter and energy within and between system components at all spatial and temporal scales. Connectivity is then a special case within disconnectivity in which the efficient transfer of matter and energy occurs within the spatiotemporal scale of interest. In this study, we explore whether disconnectivity controls the spatial patterns of sediment dynamics, and how well current methods of quantifying connectivity captures these spatial patterns. We conducted a case study within the Tahoma Creek Watershed of Mount Rainier National Park, WA, in which we present fieldwork and historical data in the form of a geomorphic map and conceptual sediment budget and map all sources of disconnectivity. These analyses are compared to methods of measuring the influence of landscape history and hillslope-channel coupling, followed by several semi-quantitative connectivity indices. Slope-Area plots clearly show the topographic signature of Pleistocene glaciations within the confines of relict cirques, while the mainstem channel appears fully adjusted to contemporary fluvial processes. Hillslope-channel coupling estimates based on the method proposed by Whiting and Bradley (1993) generally match fieldwork evidence, where the uppermost 6 km of the channel are coupled to the hillslopes, and the lowermost 7 km are decoupled. We found that the spatial distribution of sources of disconnectivity and their upslope affected areas explains the spatial patterns of sediment transfers and assumed transfer efficiencies within the watershed. Even locations with intense morphodynamics, such as Mount Rainier, are predominantly disconnected over human-timescales. The methods of quantifying sediment connectivity all performed rather well within their stated limitations and inherent resolution, although discrepancies exist. The primary sources of error result from inaccurately modelling runoff pathways and overlooking the effects of vegetation. We suggest explicitly integrating sources of disconnectivity within disconnectivity indices for improved performance and physical grounding.
Regulating emptying and transport services for faecal sludge in Sub-Saharan African cities

Publisher: name: Loughborough University
Year: 2022
Subjects: subject: 129999 Built Environment and Design not elsewhere classified
subject: FOS: Civil engineering

description: In Sub-Saharan African cities, the majority of the population relies on onsite sanitation facilities, that typically generate faecal sludge. Emptying and transport services for this faecal sludge are key components of a complete sanitation service chain, without which the sludge would be left on site, pits or tanks would overflow, and sludge would not effectively reach treatment or safe disposal sites. These services are crucial to enable safely managed on site sanitation in cities, to protect public and environmental health. To address the adverse impacts and the inadequacy of many such emptying and transport services, local governments and national entities have started organising and regulating them.The effective regulation of these services, both on paper and in practice, is the focus of this research. The research explores the current regulation in place in sub-Saharan African cities and analyses the barriers and enablers to regulating emptying and transport services. It does this by using a mixed-methods approach and a combination of three studies: a Delphi study among emptiers, an Inventory of regulatory practices, and a multiple-case study of three cities (Kampala, Lusaka, Freetown).The research concludes that there are a variety of regulatory situations in sub-Saharan African cities. Many cities have at least some regulation in place for emptying and transport services, and this regulation is often at least partially implemented. Three regulatory approaches, often combined, are commonly used by the regulators: a) command and control; b) support and incentivise; c) self-regulation. The degree of implementation of the regulation is influenced by the content of the regulation, the regulatory process (from initiation, through creation/reform to implementation), and the context. The motivation, capacity, knowledge, and resources of all stakeholders are crucial considerations to achieve regulated services. Five categories of stakeholders were found to play an important role in the regulation of emptying and transport services: regulators, monitors/enforcers, regulated, self-regulation bodies, and influencers. This research led to the development of a framework incorporating the key elements to be taken into account when regulating services. This will prove a useful guide to regulators, sanitation planners, and their development partners, when starting the process of regulating services or when wanting to understand why the enacted regulation is not being successfully implemented. It will also enable researchers to further analyse the regulation and the regulatory processes within other cities where on site sanitation facilities services are present.
The role of the c-statistic in variable selection for propensity score models

description: The applied literature on propensity scores has often cited the c-statistic as a measure of the ability of the propensity score to control confounding. However, a high c-statistic in the propensity model is neither necessary nor sufficient for control of confounding. Moreover, use of the c-statistic as a guide in constructing propensity scores may result in less overlap in propensity scores between treated and untreated subjects; this may require the analyst to restrict populations for inference. Such restrictions may reduce precision of estimates and change the population to which the estimate applies. Variable selection based on prior subject matter knowledge, empirical observation, and sensitivity analysis is preferable and avoids many of these problems.
Quantum Aspects of Massive Gravity II: Non-Pauli-Fierz Theory

description: We investigate the non-Pauli-Fierz(nPF) theory, a linearized massive gravity with a generic graviton mass term, which has been ignored due to a ghost in its spectrum and the resultant loss of unitarity. We first show that it is possible to use the Lee-Wick mechanism, a unitarization through the decay of a ghost, in order to handle the sixth mode ghost of nPF, and then check for the quantum consistency. Once proven to be consistent, nPF could become a viable candidate for a large distance modification of gravity, because it naturally solves the intrinsic problems that most dark energy/modified gravity models suffer from: It smoothly converges to general relativity at short distances, and the small graviton mass necessary to modify gravity at large scales can be stable under the radiative corrections from the minimal gravity-to-matter coupling.

description: A seguito delle osservazioni svolte, è sorta l’ipotesi che negli allievi potrebbero essersi radicate misconcezioni riguardo la relazione tra area e perimetro. Molto spesso gli allievi credono che vi sia una dipendenza stretta tra questi due concetti, che porta a credere che un perimetro maggiore implichi sempre un’area maggiore e viceversa. Il primo obiettivo della ricerca è quello di indagare le convinzioni relative alla possibile esistenza di una relazione di proporzionalità diretta tra l’area e il perimetro di una figura piana. Il secondo obiettivo del percorso progettato e sperimentato è comprendere se le eventuali concezioni errate siano profondamente radicate oppure se l’utilizzo di attività ludiche possa contribuire a correggere e adeguare tali modelli. Per raggiungere gli obiettivi, sono stati proposti sette interventi ludici volti a scoprire, identificare e verificare i differenti legami esistenti tra le due grandezze in questione. Il gioco, essendo il canale più naturale e spontaneo di comunicazione, è un potente strumento didattico che può essere impiegato efficacemente in tutte le fasi dell’istruzione. I risultati della ricerca mostrano che nel gruppo di allievi di quinta coinvolti nella ricerca si era radicata questa misconcezione; è possibile affermare che il percorso ha influenzato positivamente le convinzioni della classe. Le attività ludiche hanno contribuito alla modifica dei modelli erronei costruiti e hanno favorito l’accomodamento di nuovi modelli positivi. Relatore: Luca Crivelli.
Detecting Chameleon Dark Energy via Electrostatic Analogy

description: The late-time accelerated expansion of the universe could be caused by a scalar field that is screened on small scales, as in chameleon or symmetron scenarios. We present an analogy between thin shell configurations of such scalar fields and electrostatics, which allows calculation of the field profile for general extended bodies. Interestingly, the field demonstrates a `lightning rod' effect, where it becomes enhanced near the ends of a pointy or elongated object. Drawing from this correspondence, we show that non-spherical test bodies immersed in a background field will experience a net torque caused by the scalar field. This effect, with no counterpart in the gravitational case, can be potentially tested in future experiments.

The TeV-mass curvaton

description: We consider the constraints for a curvaton with mass m ~ 1 TeV and show that they are not consistent with a purely quadratic potential. Even if the curvaton self-interactions were very weak, they must be accounted for as they affect the dynamical evolution of the curvature perturbation. We show that the only TeV-mass curvaton interaction potential that yields the correct perturbation amplitude, decays before the dark matter freeze-out, and does not give rise to non-Gaussian perturbations that are in conflict with the present limits, is given by V_int= sigma^8/M^4. The decay width of the curvaton should be in the range Gamma= 10^-15...10^-17 GeV. The model typically predicts large non-linearity parameters f_NL and g_NL that should be observable by the Planck satellite. We also discuss various physical possibilities to obtain the required small curvaton decay rate.

Some of the tools discussed include: eMailTrackerPro to identify the physical location of an email sender; Web Historian to find the duration of each visit and the files uploaded and downloaded from the visited website; packet sniffers like Etherea to capture and analyze the data exchanged among the different computers in the network. The second half of the paper presents a survey of different IP traceback techniques like packet marking that help a forensic investigator to identify the true sources of the attacking IP packets. We also discuss the use of Honeypots and Honeynets that gather intelligence about the enemy and the tools and tactics of network intruders.
