description: We propose a Dirac neutrino portal dark matter scenario by minimally extending the particle content of the Standard Model (SM) with three right handed neutrinos ($ν_R$), a Dirac fermion dark matter candidate ($ψ$) and a complex scalar ($ϕ$), all of which are singlets under the SM gauge group. An additional $\mathbb{Z}_4$ symmetry has been introduced for the stability of dark matter candidate $ψ$ and also ensuring the Dirac nature of light neutrinos at the same time. Both the right handed neutrinos and the dark matter thermalise with the SM plasma due to a new Yukawa interaction involving $ν_R$, $ψ$ and $ϕ$ while the latter maintains thermal contact via the Higgs portal interaction. The decoupling of $ν_R$ occurs when $ϕ$ loses its kinetic equilibrium with the SM plasma and thereafter all three $\mathbb{Z}_4$ charged particles form an equilibrium among themselves with a temperature $T_{ν_R}$. The dark matter candidate $ψ$ finally freezes out within the dark sector and preserves its relic abundance. We have found that in the present scenario, some portion of low mass dark matter ($M_ψ\lesssim10$ GeV) is already excluded by the Planck 2018 data for keeping $ν_R$s in the thermal bath below a temperature of 600 MeV and thereby producing an excess contribution to $N_{\rm eff}$. The next generation experiments like CMB-S4, SPT-3G etc. will have the required sensitivities to probe the entire model parameter space of this minimal scenario, especially the low mass range of $ψ$ where direct detection experiments are still not capable enough for detection.

description: Gravitational spin-orbit interactions induce a relativistic capillary effect along open magnetic flux-tubes, that join the event horizon of a spinning black hole to infinity. It launches a leptonic outflow from electron-positron pairs created near the black hole, which terminates in an ultra-relativistic Alfvén wave. Upstream to infinity, it maintains a clean linear accelerator for baryons picked-up from an ionized ambient environment. We apply it to the origin of UHECRs and to spectral energy correlations in cosmological gamma-ray bursts. The former is identified with the Fermi-level of the black hole event horizon, the latter with a correlation $E_pT_{90}^{1/2}\simeq E_γ$ in HETE-II and Swift data.

description: The transition from tunneling to metallic contact between two surfaces does not always involve a jump, but can be smooth. We have observed that the configuration and material composition of the electrodes before contact largely determines the presence or absence of a jump. Moreover, when jumps are found preferential values of conductance have been identified. Through combination of experiments, molecular dynamics, and first-principles transport calculations these conductance values are identified with atomic contacts of either monomers, dimers or double-bond contacts.

description: Microwave, submillimetre-wave, and far-infrared phased arrays are of considerable importance for astronomy. We consider the behaviour imaging phased arrays and interferometric phased arrays from a functional perspective. It is shown that the average powers, field correlations, power fluctuations, and correlations between power fluctuations at the output ports of an imaging or interferometric phased array can be found once the synthesised reception patterns are known. The reception patterns do not have to be orthogonal or even linearly independent. It is shown that the operation of phased arrays is intimately related to the mathematical theory of frames, and that the theory of frames can be used to determine the degree to which any class of intensity or field distribution can be reconstructed unambiguously from the complex amplitudes of the travelling waves at the output ports. The theory can be used to set up a likelihood function that can, through Fisher information, be used to determine the degree to which a phased array can be used to recover the parameters of a parameterised source. For example, it would be possible to explore the way in which a system, perhaps interferometric, might observe two widely separated regions of the sky simultaneously.

description: A two-core transducer assembly using a Fe73.5Nb3Cu1Si13.5B9 ribbon to detect a change of magnetic field is proposed and tested for displacement (linear and angular) and current sensor. Two identical inductors, with the ribbon as core, are a part of two series resonance network, and are in high impedance state when excited by a small a.c field of 1MHz in absence of d.c biasing field (Hdc). When the magnetic state of one inductor is altered by biasing field, produced by a bar magnet or current carrying coil, an ac signal proportional to Hdc is generated by transducer. The results for the sensitivity and linearity with displacement (linear and angular) of a magnet and with field from the current carrying coil are presented for two particular configurations of the transducer. High sensitivities of voltage response as much as 12micro-volt/micro-meter and 3mV/degree have been obtained for the transducer as a linear and angular displacement sensor respectively in the transverse configuration of exciting a.c and biasing d.c fields.

description: Fine-grained indoor localization has attracted attention recently because of the rapidly growing demand for indoor location-based services (ILBS). Specifically, massive (large-scale) multiple-input and multiple-output (MIMO) systems have received increasing attention due to high angular resolution. This paper presents an indoor localization testbed based on a massive MIMO orthogonal frequency-division multiplexing (OFDM) system, which supports physical-layer channel measurements. Instead of exploiting channel state information (CSI) directly for localization, we focus on positioning from the perspective of multipath components (MPCs), which are extracted from the CSI through the space-alternating generalized expectation-maximization (SAGE) algorithm. On top of the available MPCs, we propose a generalized fingerprinting system based on different single-metric and hybrid-metric schemes. We evaluate the impact of the varying antenna topologies, the size of the training set, the number of antennas, and the effective signal-to-noise ratio (SNR). The experimental results show that the proposed fingerprinting method can achieve centimeter-level positioning accuracy with a relatively small training set. Specifically, the distributed uniform linear array obtains the highest accuracy with about 1.63-2.5-cm mean absolute errors resulting from the high spatial resolution.

Quaslametko and Yetko: Two Grandmother Models for Contemporary Native Education Pedagogy
Creators: name: Sterling, Shirley
Publisher: name: Canadian Journal of Native Education
Year: 2021

description: This article uses storytelling to establish and compare two Native education pedagogies as personified by two Salishan grandmothers, Quaslametko and Yetko. These women, born in the 1800s, were my mother's grandmothers. Their childrearing practices had a profound and lasting effect on my mother and my family. This article introduces the two grandmothers, Quaslametko the basket- maker and Yetko, her sister-in-law, who ivas a plant gatherer and storyteller. Direct quotes from my mother reveal the characters of the two grandmothers and their influence on the children of my mother's generation. Metaphor and sym­bolism characterize two different styles of child-adult interactions, which are linked with contemporary pedagogical methods for the purpose of contrasting two styles of teaching and to introduce Native pedagogies to non-Native teachers, and in doing so to present a case weighted toward the Yetko model while recognizing the usefulness and applicability of both models. What we can learn from Quas­lametko and Yetko has a timeless practical application for educators of Native chil­dren in any setting.

description: For any continuous zero-mean random variable (r.v.) X, a reciprocating function r is constructed, based only on the distribution of X, such that the conditional distribution of X given the (at-most-)two-point set {X,r(X)} is the zero-mean distribution on this set; in fact, a more general construction without the continuity assumption is given in this paper, as well as a large variety of other related results, including characterizations of the reciprocating function and modeling distribution asymmetry patterns. The mentioned disintegration of zero-mean r.v.'s implies, in particular, that an arbitrary zero-mean distribution is represented as the mixture of two-point zero-mean distributions; moreover, this mixture representation is most symmetric in a variety of senses. Somewhat similar representations -- of any probability distribution as the mixture of two-point distributions with the same skewness coefficient (but possibly with different means) -- go back to Kolmogorov; very recently, Aizenman et al. further developed such representations and applied them to (anti-)concentration inequalities for functions of independent random variables and to spectral localization for random Schroedinger operators. One kind of application given in the present paper is to construct certain statistical tests for asymmetry patterns and for location without symmetry conditions. Exact inequalities implying conservative properties of such tests are presented. These developments extend results established earlier by Efron, Eaton, and Pinelis under a symmetry condition.
A new process for the separation and purification of egg yolk antibodies
Creators: name: Charter, Edward
Publisher: name: University of British Columbia
Year: 2008

description: A three stage process was developed for the separation of an antibody (IgY) from industrially separated chicken egg yolk. This included aqueous extraction of the water soluble fraction (WSF) from the yolk by dilution with distilled water and pH adjustment, separation of IgY from the WSF using a cation exchange column in an automated chromatography system, and finally purification of IgY using precipitation with sodium sulphate. The overall recovery of the process was approximately 50%, and the purity 95% or greater depending on the number of precipitation steps used. An automated liquid chromatography system was developed to allow efficient study of various chromatographic media for the separation of the antibody. Analysis of breakthrough curves indicates that superficial velocity is the governing parameter in the binding of IgY to the cation exchanger. Results of a pilot scale experiment involving the application of 46.5 litres of WSF containing approximately 0.8 mg/ml IgY to a 1500 nil column are presented.

description: Brominated flame retardants (BFRs) are organobromine compounds that have an inhibitory effect on combustion chemistry. They are used commonly in plastics, textiles and electrical/electronic equipment. Polybrominated diphenyl ethers (PBDEs) is one of the most widely used group of BFRs. After the ban of PBDEs in E.E., novel BFRs (NBFRs) were used as their replacements. This study examined the occurrence of PBDEs and NBFRs in dust from classrooms (n=20) in North Greece. The sum concentrations of 20 target PBDE congeners (Σ20PBDE) in dust ranged from 58.3 ng g-1 to 1476 ng g-1 with a median value of 208 ng g-1 while the sum of 4 target compounds of NBFRs (Σ4NBFRs) ranged from 27.7 ng g-1 to 555 ng g-1 with a median value of 86.6. The most abundant compounds were found to be BDE-209 and DBDPE. The exposures to PBDEs and NBFRs via ingestion and dermal absorption of dust were several orders of magnitude lower than their corresponding Reference Dose (RfD) values

description: Significant developments in human genetics in the past few years, particularly prenatal control, have led to new possibilities in the field of prenatal diagnosis. Hemoglobinopathies are the most common hereditary genetic diseases that are transmitted from parents to children. The most common are β-thalassemia, α-thalassemia and sickle cell syndroms. Thalassemia anaemia is now considered a chronic disease, as treatment has reduced complications and increased life expectancy for sufferers. Emphasis is constantly given on improving the quality of life of the patients and preventing the inheritance of the disease. The aim of this work was to highlight the importance of prenatal control for the prevention of hereditary diseases and the importance of the Hemoglobinopathies Prevention Program in Greece. The process of genetic counseling, antenatal and pre-implantation control has greatly helped to reduce the births of children suffering but meantime they have raised important moral, social, theological and legal issues that need to be explored and understood

description: We carry out the effect of $β$-prescription for viscosity which introduced by Duschel et al. 2000 & Hure, Richard & Zhan 2001, in a standard self-gravitating thin disks. We were predicted in a self-gravitating thin disk the $β$-model will have different dynamical behavior compare the well known $α$-prescriptions. We used self-similar methods for solving the integrated equations which govern the dynamical behavior of the thin disks. We present the results of self-similar solutions of the time evolution of axisymmetric, polytropic, self-gravitating viscous disks around a new born central object. We apply a $β$-viscosity prescription which has been derived from rotating shear flow experiments ($ν=βr^2Ω$). Using reduced equations in a slow accretion limit, we demonstrate inside-out self-similar solutions after core formation in the center. Some physical quantities for $β$-disks are determined numerically.We have compared our results with $α$-disks under the same initial conditions. It has been found that the accretion rate onto the central object for $β$-disks more than $α$-disks at least in the outer regions where $β$-disks are more efficient. Our results show that Toomre instability parameter is less than one everywhere on the $β$-disk which means that in such disks gravitational instabilities can be occurred, so the $β$-disk model can be a good candidate for the origin of planetary systems. Our results show that the $β$-disks will decouple in the outer part of the disk where the self-gravity plays an important role which is in agreement with Duschl predictions.

We prove that for some parameter values of the model there is phase transition. We reduce the problem of describing by limiting Gibbs measures to the problem of solving a system of nonlinear functional equations. We extend the results obtained by Ganikhodjaev and Rozikov [Math. Phys. Anal. Geom., 2009, 12, No. 2, 141-156] on phase transition for the Ising model to the Potts model setting.

Il primo è il metodo che Luzi utilizza nel conseguire i suoi risultati teorici. La rilevanza di esso risiede nel fatto che il poeta riesce a costruire una teoria letteraria radicandola profondamente nella propria esperienza di scrittore. Il secondo punto, invece, vuole mettere in luce i contenuti stessi di questa teoria. Per questo motivo si analizzano alcuni scritti chiave del poeta che propongono un approccio e dei contenuti nuovi e originali nella discussione della natura dell’opera letteraria.

description: A brief account of the study of rare B decay $B \to K^\ast \ell^+ \ell^-$ using soft-collinear effective theory (SCET) is presented. Theoretical underpinning of this work is a factorization formula, derived to leading power in $1/m_b$ and valid to all orders in $α_s$. Partially integrated branching ratio in the dilepton squared mass range $1 {GeV}^2 \le q^2 \le 7 {GeV}^2$ and the forward-backward (FB) asymmetry of the leptons are calculated. For the zero-point of the FB asymmetry, we get $q_0^2=(4.07^{+0.16}_{-0.13}) {GeV}^2$. The scale-related uncertainty of $q_0^2$ is improved compared to the earlier estimate of the same.

description: Model-independent searches for physics beyond the Standard Model typically focus on invariant masses of two objects (jets, leptons or photons). In this study we explore opportunities for similar model-agnostic searches in multi-body invariant masses. In particular, we focus on the situations when new physics can be observed in a model-independent way in three- and four-body invariant masses of jets and leptons. Such searches may have good prospects in finding new physics in the situations when two-body invariant masses, that have been extensively explored at collider experiments in the past, cannot provide sufficient signatures for experimental observations.

This neighborhood is open in the $C^1-$topology. The construction utilizes a continuation argument and chain level result in the Floer theory of Lagrangian intersections.

Literary Samizdat and Samizdat Publics
Creators: name: Komaromi, Ann
Publisher: name: Università degli Studi di Milano
Year: 2015
Subjects: Samizdat; Literature; Journals; Leningrad; Publics

description: In this article Komaromi considers literary samizdat journals in light of public theory. Although literary samizdat journals do not conform to classic conceptions of public speech, they do yield to more recent analyses of counter-publics proposed by Nancy Fraser and Michael Warner. Picking up on the poetic aspects of public speech highlighted by Warner, Komaromi examines the publics projected by literary samizdat journals through statements about those publics, style, and bibliographic values. While not directly contesting political conditions, these literary journals amplified the implications of samizdat production and distribution to foster plurality and human connection as a basis for a better future.

description: Background and purpose — High-energy trauma to the lower limbs can result in open fractures, treated by reconstructive surgery or amputation. We examined whether socioeconomic position is associated with choice of primary treatment. Patients and methods — We performed a nationwide population-based study using the Swedish National Patient Register to identify all adult patients who between 1998 and 2013 underwent reconstruction or amputation after an open fracture below the knee. Information on socioeconomic position was collected from Statistics Sweden. Results — Of 275 individuals undergoing surgery after an open fracture below the knee during the study period, the 1st surgery was reconstructive in 58% of the patients and amputation in 42%. The chance of having an initial reconstruction was lower for women than for men (OR 0.5, 95% CI 0.3–0.9), lower with age (OR 0.97, CI 0.96–0.99), and lower for individuals without employment compared with individuals in employment (OR 0.3, CI 0.2–0.5). Primary treatment was in women associated with family composition, whereas in men it was associated with level of education. Interpretation — Choice of primary treatment after open fracture in the lower limb is affected by socioeconomic position including sex, age, employment, family composition, level of education, and income.
The electrochemical mediation of oxygen delignification of pulp with a manganese polyol complex
Creators: name: Todd, Rory
Publisher: name: University of British Columbia
Year: 2008

description: A redox cycle involving a manganese gluconate complex and oxygen in an aqueous alkaline media was investigated for its ability to delignify chemical pulp. Current applied at a cathode was used to reduce the higher oxidation states of the manganese complex. The reaction of the manganese (II) and (III) complex forms with oxygen is believed to produce hydrogen peroxide. Evidence presented in this study suggests a redox cycle was operating involving the manganese III and IV oxidation states of the manganese complex, oxygen and sufficient current. It is thought hydrogen peroxide produced in this redox cycle was responsible for the larger Kappa number and viscosity reductions observed in experimental runs employing the manganese gluconate complex/oxygen redox cycle, than in corresponding runs in the absence of the manganese complex/oxygen redox cycle. For a pulp consistency of 1 %, in 1 M sodium hydroxide, with oxygen purge, for 3 hours at 50°C and atmospheric pressure, the presence of the manganese gluconate complex and sufficient current on a platinised titanium cathode reduced the pulp Kappa number from 29 --> 17 and the viscosity from 33 --> 20 cP. In the absence of the complex and current the pulp Kappa number was reduced from 29 -- > 20 while the viscosity was reduced from 33 -- > 29 cP. The manganese complex/oxygen redox cycle did not significantly enhance the delignification or cellulose degradation reactions in factorial experiments at 20 °C or 90 °C. At 20 °C it is believed that increased peroxide stability prevented the delignification and cellulose degradation reactions. The formation of free radical species being necessary in peroxide delignification. At 90 °C it is believed the increased activity of the hydroxide ions and oxygen mask any effect of peroxide produced in the manganese complex/oxygen redox cycle. Abstract The presence of a contaminant, likely copper or iron ions, in the reactor is believed to cause the larger viscosity drop in experimental runs where the contaminant was present. It is thought that the copper and iron ions increased the production of free radical species in the bleaching mixture, thus promoting cellulose degradation.

description: Background and purpose — The quality of life (QoL) of patients with hallux valgus (HV) usually improves postoperatively. Evidence regarding the effect of HV surgery on different domains of patient QoL remains inconclusive. This systematic review and meta-analysis estimates the effect of HV surgery on patient QoL through distinguishing effects on physical domains (comprising physical function and body pain domains) using the EuroQol-5D, short form (SF) health survey-12, and SF-36 QoL scales and a visual analogue scale (VAS) score and mental and social domains using QoL scales. Patients and methods — MEDLINE, EMBASE, Cochrane Library, and Web of Science databases were systematically searched from inception to March 2019 for studies on the effect of HV surgery on patient QoL. A standardized mean difference score was calculated for each specific QoL domain (mental, social, pain, physical, and VAS) using Cohen’s d index. The pooled effect size (ES) was estimated using a random-effects model based on the DerSimonian and Laird method. Results — From 12 published studies selected, the estimated pooled ES for QoL was 1.01 (95% confidence interval [CI] 0.52–1.51; I2 = 87%) for body pain and 0.43 (CI 0.31–0.55, I2 = 35%) for physical function. Regarding the composite mental and social domains of QoL, the pooled ES estimates were 0.24 (CI 0.00–0.47, I2 = 80%) and 0.42 (CI 0.21–0.63, I2 = 6.4%), respectively. The pooled difference in means for the VAS score was –4.1 (CI –4.5 to –3.6, I2 = 90%). Interpretation — Our data showed that HV surgery decreased patients’ perceptions regarding pain. Furthermore, the data confirmed that HV surgery increased patients’ QoL, particularly concerning physical and social domains.

description: The cosmic time dependencies of $G$, $α$, $\hbar$ and of Standard Model parameters like the Higgs vev and elementary particle masses are studied in the framework of a new dark energy interpretation. Due to the associated time variation of rulers, many effects turn out to be invisible. However, a rather large time dependence is claimed to arise in association with dark energy measurements, and smaller ones in connection with the Standard Model.

description: Elder Ellen White shares her thoughts, remembrances, life experiences, and tradi­tional teachings with Jo-ann Archibald. They begin a teacher-learner cultural rela­tionship in a research context. This relationship is new but the process is old; it goes back as far as our peoples' memories reach. Educators working with First Na­tions learners are given fundamental metaphors that can be transformed to con­ temporary educational practice. Educational researchers are introduced to issues relating to collaboration, First Nations language translation, appropriateness of method, and re-presentation. ...

description: Quantum repeaters promise to deliver long-distance entanglement overcoming noise and loss in realistic quantum channels. A promising class of repeaters, based on atomic ensemble quantum memories and linear optics, follow the proposal by Duan et al [Nature 414, 413, 2001]. Here we analyse this protocol in terms of a very general model for the quantum memories employed. We derive analytical expressions for scaling of entanglement with memory imperfections, dark counts, loss and distance, and apply our results to two specific quantum memory protocols. Our methods apply to any quantum memory with an interaction Hamiltonian at most quadratic in the mode operators and are in principle extendible to more recent modifications of the original DLCZ proposal.

“Mne govorjat, kakaja bednost’ slovarja...” Il protosamizdat del periodo staliniano alla ricerca di un’espressività

description: L’estetica della letteratura afferente al circuito samizdat dopo il XX congresso del PCUS (1956) è strettamente legata alla produzione non ufficiale del periodo staliniano, a sua volta definitasi secondo una relazione antitetica alla poesia proletaria degli anni Venti. Molte delle figure di rife- rimento di questo periodo hanno attinto il proprio linguaggio e gli strumenti poetici dall'arsenale espressivo e formale del Secolo d’Argento, sebbene differenziadosene notevolmente e adattan- dolo all'estetica che essi perseguivano, intimamente alternativa a quella realsocialista. La com- plessa poetica di autori quali E. Kropivnickij, Jan Satunovskj (come anche, in un periodo succes- sivo, il “discepolo” del primo G Sapgir) e molti altri hanno attinto i tratti distintivi della propria produzione dalla rielaborazione dell’arte proletaria della prima metà degli anni Venti alla luce di una visione dissacrante e grottesca della contemporaneità, che emerge in primo luogo dall'aspetto delle loro opere poetiche.

description: The present work is a review of a series of papers, published in the last ten years, comprising an attempt to find a suitable avenue from geometry to quantum. It shows clearly that, any non-symmetric geometry admits some built-in quantum features. These features disappear completely once the geometry becomes symmetric (torsion-less). It is shown that, torsion of space-time plays an important role in both geometry and physics. It interacts with the spin of the moving particle and with its charge. The first interaction, {\bf{Spin-Torsion Interaction}}, has been used to overcome the discrepancy in the results of the COW-experiment. The second interaction, {\bf{Charge-Torsion Interaction}}, is similar to the Aharonov-Bohm effect. As a byproduct, a new version of Absolute Parallelism (AP) geometry, the Parameterized Absolute Parallelism (PAP) geometry, has been established and developed. This version can be used to construct field theories that admit some quantum features. Riemannian geometry and conventional AP-geometry are special cases of PAP-geometry.

description: Background and purpose — There is limited amount of evidence about optimal revision indications, technique, and implants when performing revision surgery for metal-on-metal (MoM) hip replacements due to adverse reaction to metal debris (ARMD). We assessed which factors are related to re-revisions and complications after a revision of MoM hip arthroplasty because of ARMD. We also aimed to provide information on optimal implants for these revisions. Patients and methods — 420 MoM total hip arthroplasties (THA) and 108 MoM hip resurfacings were implanted and later revised at our institution. We used Cox regression to analyze the factors associated with re-revisions and complications after a revision for ARMD. Results — A re-revision was performed on 27 THAs (6%) and 9 resurfacings (8%). The most common indication for re-revision was recurrent dislocation (20 hips, 4%). Complications not leading to re-revision were seen in 21 THAs (5%) and 6 resurfacings (6%). The most common complication was dislocation treated with closed reduction in 13 hips (2%). Use of revision head size > 36mm was associated with decreased risk for dislocations. Presence of pseudotumor, pseudotumor grade, pseudotumor size, or the choice of bearing couple were not observed to affect the risk for re-revision. Non-linear association was observed between preoperative cobalt and risk for re-revision. Interpretation — As dislocation was the most frequent post-revision complication, large head sizes should be used in revisions. Because size or type of pseudotumor were not associated with risk of re-revision, clinicians may have to reconsider, how much weight is put on the imaging findings when deciding whether or not to revise. In our data blood cobalt was associated with risk for re-revision, but this finding needs further assessment.
