description: Anonymity networks allow messaging with metadata privacy, providing better privacy than popular encrypted messaging applications. However, contacting a user on an anonymity network currently requires knowing their public key or similar high-entropy information, as these systems lack a privacy-preserving mechanism for contacting a user via a short, human-readable username. Previous research suggests that this is a barrier to widespread adoption. In this paper we propose Pudding, a novel private user discovery protocol that allows a user to be contacted on an anonymity network knowing only their email address. Our protocol hides contact relationships between users, prevents impersonation, and conceals which usernames are registered on the network. Pudding is Byzantine fault tolerant, remaining available and secure as long as less than one third of servers are crashed, unavailable, or malicious. It can be deployed on Loopix and Nym without changes to the underlying anonymity network protocol, and it supports mobile devices with intermittent network connectivity. We demonstrate the practicality of Pudding with a prototype using the Nym anonymity network. We also formally define the security and privacy goals of our protocol and conduct a thorough analysis to assess its compliance with these definitions.

description: We show that the charge and thermal transport measurements on ultraclean crystals of URu2Si2 reveal a number of unprecedented superconducting properties. The uniqueness is best highlighted by the peculiar field dependence of thermal conductivity including the first order transition at Hc2 with a reduction of entropy flow. This is a consequence of multi-band superconductivity with compensated electronic structure in the hidden order state of this system. We provide strong evidence for a new type of unconventional superconductivity with two distinct gaps having different nodal topology.

description: We review some recent progress in the theory of electroweak radiative corrections in semileptonic decay processes. The resurrection of the so-called Sirlin's representation based on current algebra relations permits a clear separation between the perturbatively-calculable and incalculable pieces in the $\mathcal{O}(G_Fα)$ radiative corrections. The latter are expressed as compact hadronic matrix elements that allow systematic non-perturbative analysis such as dispersion relation and lattice QCD. This brings substantial improvements to the precision of the electroweak radiative corrections in semileptonic decays of pion, kaon, free neutron and $J^P=0^+$ nuclei that are important theory inputs in precision tests of the Standard Model. Unresolved issues and future prospects are discussed.

Effective epidemic containment strategy in hypergraphs

Subjects: subject: Physics and Society (physics.soc-ph)

description: Recently, hypergraphs have attracted considerable interest from the research community as a generalization of networks capable of encoding higher-order interactions, which commonly appear in both natural and social systems. Epidemic dynamics in hypergraphs has been studied by using the simplicial susceptible-infected-susceptible ($s$-SIS) model; however, the efficient immunization strategy for epidemics in hypergraphs is not studied despite the importance of the topic in mathematical epidemiology. Here, we propose an immunization strategy that immunizes hyperedges with high simultaneous infection probability (SIP). This strategy can be implemented in general hypergraphs. We also generalize the edge epidemic importance (EI)-based immunization strategy, which is the state of the art in complex networks. However, it does not perform as well as the SIP-based method in hypergraphs despite its high computational cost. We also show that immunizing hyperedges with high H-eigenscore effectively contains the epidemics in uniform hypergraphs. A high SIP of a hyperedge suggests that the hyperedge is a "hotspot" of the epidemic process. Therefore, SIP can be used as a centrality measure to quantify a hyperedge's influence on higher-order dynamics in general hypergraphs. The effectiveness of the immunization strategies suggests the necessity of scientific, data-driven, systematic policy-making for epidemic containment.

For low frequencies (< 1 GHz), digital techniques can be used to coherently measure the instantaneous, local field vectors and to manipulate them in software. This opens up for new types of experiments that go beyond those currently possible to perform in optics, for information-rich radio physics applications such as radio astronomy, and for novel wireless communication concepts.

description: We present a calculation of the full next-to-leading order QCD corrections to the scattering process pp \to t tbar Z. This channel will be used to measure the t tbar Z electroweak couplings at the Large Hadron Collider. These couplings cannot be directly measured in current experiments. To obtain these results, we utilize a novel, completely numerical approach to performing higher order QCD calculations. We find that for reasonable values of the renormalization and factorization scales the QCD corrections increase the leading order result by 35 percent, while reducing the theoretical error arising from uncalculated higher order corrections to approximately 10 percent.

description: The paper proposes an optimal management strategy for a system composed by a battery and a photovoltaic power plant. This integrated system is called to deliver the photovoltaic power and to simultaneously provide droop-based primary frequency regulation to the main grid. The battery state-of-energy is controlled by power offset signals, which are determined using photovoltaic energy generation forecasts and predictions of the energy required to operate frequency regulation. A two level control architecture is developed. A day-ahead planning algorithm schedules the energy profile which is traded at the day-ahead market and defines the primary control reserve that the integrated system is able to provide in the considered day. During the day operations, a second level algorithm corrects the dispatched plan using updated information, in order to guarantee a continuous and reliable service. Both control algorithms take into account the uncertainties of the photovoltaic generation and of the frequency dynamics using stochastic optimization.
Analysis of the mechanisms of resistance to Epidermal growth factor receptor inhibitors and development of multiple targeted strategies
Creators: name: Rosa, Roberta
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: Background. Primary and acquired resistance to selective Epidermal growth factor receptor (EGFR) inhibitors remains the most significant obstacle to the success of these targeted agents in cancer therapy. The mechanisms of resistance involve the activation of alternative signaling pathways able to bypass EGFR blockade, and Akt activation and VEGF induction have been described in EGFR inhibitor-resistant tumors. Combined inhibition of EGFR and other signaling proteins has become an effective approach to efficiently inhibit compensatory escape pathways, stimulating the search for further determinants of resistance as basis for novel therapeutic strategies.
Aim of the study. The purpose of this study is to examine the signaling mechanisms operating in human cancers with intrinsic or acquired resistance to EGFR-targeted therapies and responsible for the lack of response to EGFR inhibitors. To this aim, we established human cancer cell lines with various degrees of EGFR expression and sensitivity to EGFR inhibitors and analyzed signal transducers under the control of EGFR-dependent and –independent pathways.
Results. Multitargeted inhibitor vandetanib (ZD6474) inhibited human endothelial cells survival thanks to inhibition of both VEGFRs and EGFR signaling pathways. Vandetanib also inhibited the growth and the phosphorylation of Akt and its effector p70S6 kinase in both, wild-type and EGFR inhibitor-resistant human colon, prostate and breast cancer cells. We found that the resistant cell lines exhibit, as common features, VEGFR-1/Flt-1 overexpression, increased secretion of VEGF and placental growth factor (PlGF), and augmented migration capabilities, and that vandetanib is able to antagonize them. Accordingly, a new kinase assay revealed that in addition to VEGFR-2, RET and EGFR, vandetanib efficiently inhibits also VEGFR-1; this capability plays a key role in determining its activity on EGFR drugs-resistant tumors. The contribution of VEGFR-1 to the resistant phenotype was further supported by the demonstration that VEGFR-1 silencing in resistant cells restored sensitivity to anti-EGFR drugs and impaired migration capabilities, while exogenous VEGFR-1 overexpression in wild-type cells conferred resistance to these agents.
Conclusions. This study demonstrates that VEGFR-1 contributes to anti-EGFR drugs resistance in different human cancer models. Moreover, vandetanib inhibits VEGFR-1 activation, cell proliferation and migration, suggesting its potential utility in patients resistant to EGFR inhibitors. Since vandetanib is successfully under investigation in several clinical studies, these data may be important for its clinical development.

Correlation functions particularly considered are the one-particle Green's function and the density-density correlation function both for any interaction strength and for arbitrary particle densities. In particular for the free fermion model, our formulae reproduce the known exact results. Form factors of local fermion operators are also calculated for a finite system.

description: The paper proposes a multi-body electromagnetic (EM) model for the quantitative evaluation of the influence of multiple human bodies in the surroundings of a radio link. Modeling of human-induced fading is the key element for the development of real-time Device-Free (or passive) Localization (DFL) and body occupancy tracking systems based on the processing of the Received Signal Strength (RSS) data recorded by radio-frequency devices. The proposed physical-statistical model, is able to relate the RSS measurements to the position, size, orientation, and random movements of people located in the link area. This novel EM model is thus instrumental for crowd sensing, occupancy estimation and people counting applications for indoor and outdoor scenarios. The paper presents the complete framework for the generic N-body scenario where the proposed EM model is based on the knife-edge approach that is generalized here for multiple targets. The EM-equivalent size of each target is then optimized to reproduce the body-induced alterations of the free space radio propagation. The predicted results are then compared against the full EM simulations obtained with a commercially available simulator. Finally, experiments are carried out to confirm the validity the proposed model using IEEE 802.15.4-compliant industrial radio devices.

description: We present results of MUSE-ALMA Halos, an ongoing study of the Circumgalactic Medium (CGM) of galaxies ($z \leq$ 1.4). Using multi-phase observations we probe the neutral, ionised and molecular gas in a sub-sample containing six absorbers and nine associated galaxies in the redshift range $z \sim 0.3-0.75$. Here, we give an in-depth analysis of the newly CO-detected galaxy Q2131-G1 ($z=0.42974$), while providing stringent mass and depletion time limits for the non-detected galaxies. Q2131-G1 is associated with an absorber with column densities of $\textrm{log}(N_\textrm{HI}/\textrm{cm}^{-2}) \sim 19.5$ and $\textrm{log}(N_{\textrm{H}_2}/\textrm{cm}^{-2}) \sim 16.5$, has a star formation rate of $\textrm{SFR} = 2.00 \pm 0.20 \; \textrm{M}_{\odot} \textrm{yr}^{-1}$, a dark matter fraction of $f_\textrm{DM}(r_{1/2}) = 0.24 - 0.54$ and a molecular gas mass of $M_\textrm{mol} = 3.52 ^{+3.95}_{-0.31} \times 10^9 \; \textrm{M}_{\odot}$ resulting in a depletion time of $τ_\textrm{dep} < 4.15 \; \textrm{Gyr}$. Kinematic modelling of both the CO (3--2) and [OIII] $λ5008$ emission lines of Q2131-G1 shows that the molecular and ionised gas phases are well aligned directionally and that the maximum rotation velocities closely match. These two gas phases within the disk are strongly coupled. The metallicity, kinematics and orientation of the atomic and molecular gas traced by a two-component absorption feature is consistent with being part of the extended rotating disk with a well-separated additional component associated with infalling gas. Compared to emission-selected samples, we find that HI-selected galaxies have high molecular gas masses given their low star formation rate. We consequently derive high depletion times for these objects.

description: We present the results of the ethynyl (C2H) emission line observations towards the HII regions S255 and S257 and the molecular cloud between them. Radial profiles of line brightness, column density, and abundance of C2H are obtained. We show that the radial profile of the ethynyl abundance is almost flat towards the HII regions and drops by a factor of two towards the molecular cloud. At the same time, we find that the abundance of ethynyl is at maximum towards the point sources in the molecular cloud -- the stars with emission lines or emitting in X-ray. The line profiles are consistent with the assumption that both HII regions have front and back neutral walls that move relative to each other.

The oscillation is shown to be due to the Aharonov-Bohm effect of a charged exciton in a quantum tube. No quadratic shift in photoluminescence peak energies is observed, which is a characteristic feature of a thin quantum tube with a single channel surrounding the magnetic flux through the tube.

Multifunctional role of PED/PEA15 in cell death and cell motility in human non small cell lung cancer (NSCLC)
Creators: name: Zanca, Ciro
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: PED (phosphoprotein enriched in diabetes) is a 15 KDa protein involved in many cellular pathways and human diseases, including type II diabetes and cancer. We recently reported its overexpression in breast and lung cancers, and B-cell chronic lymphocytic leukemia (B-CLL). Furthermore, PED mediated resistance to chemotherapic agents in breast cancer cell lines and TRAIL (TNF-Related Apoptosis Inducing Ligand) treatment in primary B-CLL cells and lung cancer cell lines. Then, we show that PED function and expression are reguated by vitamin D3. To better understand its role in cancer, we focused on PED interactome characterization in non small cell lung cancer (NSCLC) cell line, A459. By the Tandem Affinity Purification (TAP), we have identified Rac1, member of mammalian Rho GTPase proteins family, as a PED-interacting protein, which is involved in many cellular processes, such as migration and invasion. Here we show that PED stimulates migration and invasion in Rac1-dependent manner in non small cell lung cancer. In conclusion, this is teh first report showing that PED and Rac1 interact and that this interaction regulates cell migration/invasion process through ERK1/2 pathway.

Large classes of group divisible codes are constructed which enabled the determination of the sizes of optimal constant-composition codes of weight three (and specified distance), leaving only four cases undetermined. Previously, the sizes of constant-composition codes of weight three were known only for those of sufficiently large length.

Modelli per la gestione e manutenzione delle opere di architettura: possibili applicazioni dell’analisi dei sistemi dinamici alla previsione e valutazione della durabilità
Creators: name: Fornaro, Giuseppina
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2006

description: Il lavoro svolto punta a dimostrare l’opportunità di integrare l’attuale modellazione sistemica delle opere di architettura con nuove forme di rappresentazione che possano aiutare a risolvere, in modo più appropriato ed efficace, le problematiche inerenti la fase gestionale del processo edilizio strettamente connessa alle trasformazioni fisiche dell’edificio.
L’attuale normativa affronta l’indiscutibile difficoltà a stabilire con esattezza il tempo durante il quale un componente conserva prestazioni accettabili esaltando l’utilizzo di “informazioni di ritorno” attraverso cui regolare la frequenza degli interventi secondo un approccio del tipo black-box . Quest’impostazione presenta lo svantaggio di non fornire indicazioni sulla natura del processo e le informazioni acquisite restano valide per il singolo caso considerato.
In altri ambiti disciplinari, la necessità di prevedere il comportamento futuro di sistemi, anche complessi, al fine di controllarne e regolarne le trasformazioni nel tempo, ha orientato la ricerca verso lo sviluppo di tecniche di modellazione capaci di prevedere la modalità e l’entità di tali trasformazioni.
In questa direzione sono state sperimentate alcune possibilità di trasferimento, all’ambito della gestione e manutenzione degli organismi edilizi, mostrando i vantaggi che possono derivare dall’introduzione di nuove forme di approccio. Ad esempio, è stata sperimentata un’applicazione sulla classe degli elementi tecnici “infissi esterni”. La prima applicazione ha riguardato l’uso della logica fuzzy per la stima dell’Actual working life che valuta la durabilità di un elemento tecnico in condizioni di sollecitazione e manutenzione quanto più possibile coincidenti con le reali condizioni di esercizio. Tale operazione ha permesso di calcolare la durabilità differenziata di tali elementi tecnici e successivamente di sperimentare l’utilizzo di una Matrice di Leslie attraverso cui ottenere la distribuzione nel tempo del numero di infissi che periodicamente sono soggetti ad interventi di manutenzione o sostituzione. Tale strumento consente di stabilire i costi di manutenzione degli infissi nel periodo di tempo che coincide con la vita utile dell’intero edificio.

description: We continue our study of F-thresholds begun in math/0607660 by an in depth analysis of the hypersurface case. We use the D--module theoretic description of generalized test ideals which allows us to show that in any F--finite regular ring the F-thresholds of hypersurfaces are discrete and rational (in math/0607660 the finite type over a field case was shown for arbitrary ideals). Furthermore we show that any limit of F-pure thresholds of principal ideals in bouneded dimension is again an F-pure-threshold, hence in particular the limit is rational. The study of the set of F-pure-thresholds leads to natural analogs of conjectures of Shokurov and Kollár (for log canonical thresholds) in the case of F-pure-thresholds.

description: Detection of gravitational waves (GW) from highly eccentric binary black hole (BBH) systems can provide insight into their dynamics and formation. To date, all of the LIGO-Virgo BBH detections have been made using quasi-circular templates in their initial discovery. However, recent studies have found some of these systems to be compatible with high eccentricity in the LIGO band, $e_{10 \textrm{Hz}} > 0.1$, possibly pointing to a population of sources that are challenging to detect. Current low-latency search methods used with ground-based GW detector data are not well equipped to detect highly eccentric sources. Template-based, matched-filter searches require accurate eccentric waveform models that are computational expensive. Unmodeled burst searches are designed to detected localized excess power and are unable to identify multiple isolated bursts, as would originate from a single highly eccentric BBH. Therefore, we propose a signal-based prior that can be incorporated into an existing GW burst search to target highly eccentric BBHs. Our eccentric burst prior is based on the Newtonian burst model described by Loutrel & Yunes (2017). As a proof of concept, we test our method on simulated data and find that for intermediate SNR $\sim3-6$ signals using the eccentric burst prior more effectively localizes GW bursts when compared to a uniform prior.

description: We explore millimeter line diagnostics of an obscuring molecular torus modeled by a hydrodynamic simulation with three-dimensional nonLTE radiative transfer calculations. Based on the results of high-resolution hydrodynamic simulation of the molecular torus around an AGN, we calculate intensities of HCN and HCO^{+} rotational lines as two representative high density tracers. The three-dimensional radiative transfer calculations shed light on a complicated excitation state in the inhomogeneous torus, even though a spatially uniform chemical structure is assumed. Our results suggest that HCN must be much more abundant than HCO^{+} in order to obtain a high ratio ($R_{HCN/HCO+}\sim 2$) observed in some of the nearby galaxies. There is a remarkable dispersion in the relation between integrated intensity and column density, indicative of possible shortcomings of HCN(1-0) and HCO^{+}(1-0) lines as high density tracers. The internal structures of the inhomogeneous molecular torus down to subparsec scale in external galaxies will be revealed by the forthcoming Atacama Large Millimeter/submillimeter Array (ALMA). The three-dimensional radiative transfer calculations of molecular lines with high-resolution hydrodynamic simulation prove to be a powerful tool to provide a physical basis for molecular line diagnostics of the central regions of external galaxies.

description: The impact of spatial correlation on the performance limits of multielement antenna (MEA) channels is analyzed in terms of the diversity-multiplexing tradeoff (DMT) at finite signal-to-noise ratio (SNR) values. A lower bound on the outage probability is first derived. Using this bound accurate finite-SNR estimate of the DMT is then derived. This estimate allows to gain insight on the impact of spatial correlation on the DMT at finite SNR. As expected, the DMT is severely degraded as the spatial correlation increases. Moreover, using asymptotic analysis, we show that our framework encompasses well-known results concerning the asymptotic behavior of the DMT.

description: For a tripartite pure state superposed by two individual states, the bipartitely shared entanglement can always be achieved by local measurements of the third party. Consider the different aims of the third party, i.e. maximizing or minimizing the bipartitely shared entanglement, we find bounds on both the possible bipartitely shared entanglement of the superposition state in terms of the corresponding entanglement of the two states being superposed. In particular, by choosing the concurrence as bipartite entanglement measure, we obtain calculable bounds for tripartite $(2\otimes 2\otimes n)$ -dimensional cases.

Claustrophobic Visions of the Asylum: The Photobooks of the Italian Psychiatric Reform
Creators: name: Sforza Tarabochia, Alvise Sforza
Publisher: name: Between
Year: 2021

description: In this article, I compare the strategies of visual representation employed in the two 1969 photobooks Gli esclusi (D’Alessandro-Piro) and Morire di classe (Berengo Gardin et al.). These photobooks have been the photographic protagonists of the reform of psychiatric health care that, fed by the upheavals of the late 1960s, brought about the closure of psychiatric asylums in 1978 thanks to the famous Law 180. I will specifically focus on the representation of claustrophobic spaces in their relationship with the bodies of inmates compared to the traditional iconography of madness. This article aims to show that these photobooks (while employing radically different strategies of representation) aim at providing a visual translation of the pivotal philosophical coordinates that guided the reform of psychiatric health care.

description: We describe a simple AC susceptometer built in-house that can be used to make high-resolution measurements of the magnetic susceptibility of high-temperature superconductors in an undergraduate physics lab. Our system, cooled using liquid nitrogen, can reach a base temperature of 77 K. Our apparatus does not require gas handling systems or PID temperature controllers. Instead, it makes use of a thermal circuit that is designed to allow the sample to cool on a time scale that is suitable for an undergraduate lab. Furthermore, the temperature drift rate at the superconducting transition temperature $T_\mathrm{c}$ is low enough to allow for precise measurements of the complex magnetic susceptibility through $T_\mathrm{c}$, even for single-crystal samples with exceedingly sharp superconducting transitions. Using an electromagnet, we were able to apply static magnetic fields up to 63 mT at the sample site. By measuring the change in susceptibility as a function of the strength of an applied of static magnetic field, we were able to estimate the lower critical field $H_\mathrm{c1}$ of a single-crystal sample of optimally-doped YBa$_2$Cu$_3$O$_{6.95}$ at 77 K. We also investigated the mixed state of a sintered polycrystalline sample of YBa$_2$Cu$_3$O$_{6+y}$.

description: We investigate the possibility of a dark energy universe emerging from an action with higher-order string loop corrections to Einstein gravity in the presence of a massless dilaton. These curvature corrections (up to $R^4$ order) are different depending upon the type of (super)string model which is considered. We find in fact that Type II, heterotic, and bosonic strings respond differently to dark energy. A dark energy solution is shown to exist in the case of the bosonic string, while the other two theories do not lead to realistic dark energy universes. Detailed analysis of the dynamical stability of the de-Sitter solution is presented for the case of a bosonic string. A general prescription for the construction of a de-Sitter solution for the low-energy (super)string effective action is also indicated. Beyond the low-energy (super)string effective action, when the higher-curvature correction coefficients depend on the dilaton, the reconstruction of the theory from the universe expansion history is done with a corresponding prescription for the scalar potentials.

description: We review methods to shuttle quantum particles fast and robustly. Ideal robustness amounts to the invariance of the desired transport results with respect to deviations, noisy or otherwise, from the nominal driving protocol for the control parameters; this can include environmental perturbations. "Fast" is defined with respect to adiabatic transport times. Special attention is paid to shortcut-to-adiabaticity protocols that achieve, in faster-than-adiabatic times, the same results of slow adiabatic driving.

Effects of periodicity in observation scheduling on parameter estimation of pulsar glitches

description: In certain pulsar timing experiments, where observations are scheduled approximately periodically (e.g. daily), timing models with significantly different frequencies (including but not limited to glitch models with different frequency increments) return near-equivalent timing residuals. The average scheduling aperiodicity divided by the phase error due to time-of-arrival uncertainties is a useful indicator of when the degeneracy is important. Synthetic data are used to explore the effect of this degeneracy systematically. It is found that phase-coherent tempo2 or temponest-based approaches are biased sometimes toward reporting small glitch sizes regardless of the true glitch size. Local estimates of the spin frequency alleviate this bias. A hidden Markov model is free from bias towards small glitches and announces explicitly the existence of multiple glitch solutions but sometimes fails to recover the correct glitch size. Two glitches in the UTMOST public data release are re-assessed, one in PSR J1709$-$4429 at MJD 58178 and the other in PSR J1452$-$6036 at MJD 58600. The estimated fractional frequency jump in PSR J1709$-$4429 is revised upward from $Δf/f = (54.6\pm 1.0) \times 10^{-9}$ to $Δf/f = (2432.2 \pm 0.1) \times 10^{-9}$ with the aid of additional data from the Parkes radio telescope. We find that the available UTMOST data for PSR J1452$-$6036 are consistent with $Δf/f = 270 \times 10^{-9} + N/(fT)$ with $N = 0,1,2$, where $T \approx 1\,\text{sidereal day}$ is the observation scheduling period. Data from the Parkes radio telescope can be included, and the $N = 0$ case is selected unambiguously with a combined dataset.

description: Searching for lopsided/interacting objects among ~1500 isolated galaxies yields only eight strongly disturbed galaxies which may be explained as a result of their interaction with massive dark objects. We present results of spectral and photometric observations of these galaxies performed with the 6-m telescope that lead to significant restriction on cosmic abundance of dark galaxies.

description: Edge computing is a fast-growing and much needed technology in healthcare. The problem of implementing artificial intelligence on edge devices is the complexity and high resource intensity of the most known neural network data analysis methods and algorithms. The difficulty of implementing these methods on low-power microcontrollers with small memory size calls for the development of new effective algorithms for neural networks. This study presents a new method for analyzing medical data based on the LogNNet neural network, which uses chaotic mappings to transform input information. The method effectively solves classification problems and calculates risk factors for the presence of a disease in a patient according to a set of medical health indicators. The efficiency of LogNNet in assessing perinatal risk is illustrated on cardiotocogram data obtained from the UC Irvine machine learning repository. The classification accuracy reaches ~91% with the ~3-10 kB of RAM used on the Arduino microcontroller. Using the LogNNet network trained on a publicly available database of the Israeli Ministry of Health, a service concept for COVID-19 express testing is provided. A classification accuracy of ~95% is achieved, and ~0.6 kB of RAM is used. In all examples, the model is tested using standard classification quality metrics: precision, recall, and F1-measure. The LogNNet architecture allows the implementation of artificial intelligence on medical peripherals of the Internet of Things with low RAM resources and can be used in clinical decision support systems.

An economic analysis of public housing in Yellowknife, Northwest Territories
Creators: name: Steele, Margaret Jean
Publisher: name: University of British Columbia

description: For many years, social housing policy in Canada has relied upon supply-side programs. Recently, these programs have come under criticism for failing to serve the needs of poor households, precipitating a philosophical shift toward income supplement programs. While evaluations of past programs support this shift, most studies have been done at the national level and may not reflect the housing needs of specific regions or communities in Canada. This study evaluates a supply-side housing program for one community in northern Canada - Yellowknife, Northwest Territories. Drawing upon the tools of welfare economics, the study evaluates the Public Housing Program in Yellowknife in terms of economic efficiency and equity. The study analyses the program from the viewpoints of the Canadian public and the residents of the N.W.T. In both cases, the Net Present Value, calculated from measurable costs and benefits, is negative suggesting the program is not economically efficient. Non-tenant benefits of between $446,082 and $966,955 per year are required to justify the program from the national perspective and between $123,724 and $320,304 from the territorial perspective. The analysis suggests the program is promoting a small degree of equity. Benefits from the program are greater for households with lower incomes and decline by approximately $11 for every $100 increase in annual household income. The program supports horizontal equity with respect to age of household head, but there is some inequality with respect to sex as female-led households receive significantly greater benefits than their male counterparts. The results of the study are consistent with the economics literature. As expected, justification of the Public Housing Program in Yellowknife must appeal to notions other than economic efficiency. Advocates of the program may find support in the equity achievements of the program or in recent research suggesting that public housing programs have smaller work disincentive effects than programs of cash transfers.
