Food Insecurity in Patients With HIV: Recommendations for CrescentCare in New Orleans
Creators: name: Parent, Jennifer
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: CrescentCare, an organization in New Orleans, Louisiana, provides healthcare services and resources to uninsured and underserved populations with a specific focus on individuals with the human immunodeficiency virus (HIV). Data and input from CrescentCare staff indicate food insecurity, which is a lack of access to adequate and nutritious food, is a growing concern for people living with HIV in the Greater New Orleans area. Food insecurity and HIV disproportionately affect low-income and minority populations, and the concurrence of these conditions may lead to an increased risk of HIV transmission, poor HIV-related health outcomes, increased medical costs, decreased quality of life, and an increase in health disparities. This paper analyzes the association between food insecurity and HIV and provides recommendations for CrescentCare to better address the high prevalence of food insecurity in the HIV positive population. These recommendations include: 1. utilization of a two-item, validated food insecurity screening instrument at initial and annual case management interviews, 2. implementation of an acuity scale based on patients’ needs for the Food For Friends Pantry, and 3. referrals to the CrescentCare dietitians for patients who screen positive for food insecurity. These recommendations should lead to a decrease in the prevalence or severity of food insecurity in patients with HIV at CrescentCare, and successful implementation of these recommendations would provide data and guidelines for other organizations.

description: Given a number field $K$ and a polynomial $f(z) \in K[z]$, one can naturally construct a finite directed graph $G(f,K)$ whose vertices are the $K$-rational preperiodic points of $f$, with an edge $α\to β$ if and only if $f(α) = β$. The dynamical uniform boundedness conjecture of Morton and Silverman suggests that, for fixed integers $n \ge 1$ and $d \ge 2$, there are only finitely many isomorphism classes of directed graphs $G(f,K)$ as one ranges over all number fields $K$ of degree $n$ and polynomials $f(z) \in K[z]$ of degree $d$. In the case $(n,d) = (1,2)$, Poonen has given a complete classification of all directed graphs which may be realized as $G(f,\mathbb{Q})$ for some quadratic polynomial $f(z) \in \mathbb{Q}[z]$, under the assumption that $f$ does not admit rational points of large period. The purpose of the present article is to continue the work begun by the author, Faber, and Krumm on the case $(n,d) = (2,2)$. By combining the results of the previous article with a number of new results, we arrive at a partial result toward a theorem like Poonen's -- with a similar assumption on points of large period -- but over all quadratic extensions of $\mathbb{Q}$.

description: Railway transport is effective and reliable only if it has best communication and signaling system with safety, reliability and good quality of service which are maintained by railway management and communication system. By implementing latest technologies for railway communication railway transportation can be made safer, efficient, and more accessible. This research work focuses on the study of Ultra wide band (UWB) radio based wireless communication system as an auxiliary or alternative communication system for Addis Ababa Light rail transit (AA-LRT) tunnel at piassa (Gyorgis), whose main task is to maintain an uninterrupted data transmission between train driver to wayside controller. The much larger bandwidth of ultra-wideband allows a very high data rate (up to maximum 480 Mbps), which is beneficial in case of emergency in railway networks. This research studied the rectangular shaped railway tunnel environment as wireless channel by considering ray theory model of wave propagation (modal analysis and ray tracing) and the effect of the curvature of the tunnel on the wave propagation.

description: Recientemente, el debate sobre la práctica de cirugías estéticas en Colombia ha tomado relevancia e, incluso, se  ha  dado una especie de  “alarma” por  la  concurrencia de hombres y mujeres para  la realización de estos procedimientos. Desde que el diario inglés The Guardian publicó, en el mes de abril, su reportaje gráfico titulado“ Liposucción adolescente y piñatas tetonas – La narco estética en Colombia”, la preocupación por esta serie de estereotipos en la población se ha incrementado. En algunos, a favor de la ejecución de cirugías como ideal de belleza; en otros, con total rechazo por la imagen que se está proyectando mundialmente de las mujeres colombianas. Tanto así que, en el Congreso de la República, actualmente se están discutiendo dos proyectos de Ley de iniciativa del senador Mauricio Lizcano, del Partido de la U, orientados hacia la regulación delas prácticas de cirugías estéticas en Colombia.

description: This study offers a literary analysis of Rifaat Alareer's poignant poem, "If I Must Die," exploring its themes of resilience, sacrifice, and the struggle for freedom within the context of the Palestinian experience. Through a close examination of the poem's imagery, symbolism, and structure, the analysis delves into how Alareer portrays the inevitability of death not as an act of surrender but as a powerful form of resistance. The study highlights the poet's use of vivid language to reflect the paradoxical nature of life under occupation, where beauty and destruction coexist. By focusing on the concept of martyrdom and the enduring spirit of the Palestinian people, this analysis underscores how the poem serves as a testament to the resilience and hope that persists even in the face of mortality.

description: A quantum two-path interferometer allows for direct measurement of the transmission phase shift of an electron, providing useful information on coherent scattering problems. In mesoscopic systems, however, the two-path interference is easily smeared by contributions from other paths, and this makes it difficult to observe the \textit{true} transmission phase shift. To eliminate this problem, multi-terminal Aharonov-Bohm (AB) interferometers have been used to derive the phase shift by assuming that the relative phase shift of the electrons between the two paths is simply obtained when a smooth shift of the AB oscillations is observed. Nevertheless the phase shifts using such a criterion have sometimes been inconsistent with theory. On the other hand, we have used an AB ring contacted to tunnel-coupled wires and acquired the phase shift consistent with theory when the two output currents through the coupled wires oscillate with well-defined anti-phase. Here, we investigate thoroughly these two criteria used to ensure a reliable phase measurement, the anti-phase relation of the two output currents and the smooth phase shift in the AB oscillation. We confirm that the well-defined anti-phase relation ensures a correct phase measurement with a quantum two-path interference. In contrast we find that even in a situation where the anti-phase relation is less well-defined, the smooth phase shift in the AB oscillation can still occur but does not give the correct transmission phase due to contributions from multiple paths. This indicates that the phase relation of the two output currents in our interferometer gives a good criterion for the measurement of the \textit{true} transmission phase while the smooth phase shift in the AB oscillation itself does not.

Las producciones de entretenimiento de Walt Disney como herramienta de guerra: Education for Death y el discurso contra el nazismo en la Segunda Guerra mundial

description: Las herramientas de transmisión de un discurso político son varias. Pero, a la hora de trabajar respecto de la Segunda Guerra Mundial y haciendo alusión a los Estados Unidos, es de precisa importancia evaluar las producciones cinematográficas que se desarrollaron durante este periodo. Teniendo en cuenta lo anterior, cabe preguntarse cómo las caricaturas de Walt Disney sirvieron para proyectar el  discurso político contra el nazismo de Estados Unidos, durante la  Segunda Guerra Mundial. Debido a que las teorías mainstream de Relaciones Internacionales se han quedado cortas de elementos para evaluar el mundo contemporáneo, y que existe un aspecto llamativo en cuanto a la estrategia escogida por el gobierno estadounidense para transmitir el discurso contra el nazismo, este ensayo pretende evaluar,  mediante una  teoría posestructuralista, una  herramienta que,  si  bien buscaba el entretenimiento de una audiencia, ha servido para fines políticos. Se  puede afirmar que  las  caricaturas de  Walt  Disney –siendo Education for  Death un  ejemplo concreto– sirvieron para proyectar el discurso político de Estados Unidos porque, además de ser financiadas por el gobierno estadounidense, transmitían un mensaje claro de rechazo al enemigo (el nazismo), valiéndose de tres herramientas clave: la simulación, la vigilancia y la velocidad.

description: This study describes a review of Chapter 21 of Anglo-American Cataloguing Rules, 2nd ed. Rev., (Choice of Access Points). Each rule from this Chapter was analyzed to determine its purpose, and whether or not this purpose is useful in the online catalog

Thirteen rules were marked as questionable because they limit access primarily to save space in a card catalog environment. The concept of main entry is also challenged as unnecessary in the online environment. Overall, few rules are found to be of questionable value in the online catalog, but possible modifications to these rules have the potential to improve user access.

description: El Cementerio Central hace parte del patrimonio histórico de los capitalinos y se ha convertido en el plan cultural para algunos bogotanos. A pesar de los esfuerzos de la alcaldía para mantener el lugar abierto a diferentes actividades pedagógicas, el camposanto se encuentra en el olvido. Lamentablemente, Colombia es un país sin memoria y desconoce a esos hombres y mujeres que manifestaron abiertamente sus  diferencias;  liberales y  conservadores, que  defendían sus  ideales, desde las  zonas rurales  hasta las  urbanas.  Hoy  muchos de  esos  personajes descansan en  el cementerio central, pero nadie los conoce o pocos los recuerdan. Empecemos por su historia. Colombia fue colonizada por españoles, por lo tanto, sus costumbres y culturas fueron impuestas. Hasta el siglo XIX, se enterraban los muertos en bóvedas en el interior delas iglesias, al parecer, este sistema no funcionó porque se propagó una plaga que dejó enfermos y muertos, así que Carlos III dio la orden para la edificación de un cementerio. El 15 de octubre de1827, Simón Bolívar firmó  un  decreto que  prohibía los  entierros en  las  iglesias de  la  capital. Finalmente, el  cementerio fue  construido por  Pío  Domínguez y  Nicolás León, y  puesto en funcionamiento en 1836.

description: Horizontal Branch stars belong to an advanced stage in the evolution of the oldest stellar galactic population, occurring either as field halo stars or grouped in globular clusters. The discovery of multiple populations in these clusters, that were previously believed to have single populations gave rise to the currently accepted theory that the hottest horizontal branch members (the blue hook stars, which had late helium-core flash ignition, followed by deep mixing) are the progeny of a helium-rich "second generation" of stars. It is not known why such a supposedly rare event (a late flash followed by mixing) is so common that the blue hook of ω Cen contains \sim 30% of horizontal branch stars 10 , or why the blue hook luminosity range in this massive cluster cannot be reproduced by models. Here we report that the presence of helium core masses up to \sim 0.04 solar masses larger than the core mass resulting from evolution is required to solve the luminosity range problem. We model this by taking into account the dispersion in rotation rates achieved by the progenitors, whose premain sequence accretion disc suffered an early disruption in the dense environment of the cluster's central regions where second-generation stars form. Rotation may also account for frequent late-flash-mixing events in massive globular clusters.

description: This paper collects a set of open research questions on how to visualize sociodemographic data. Sociodemographic data is a common part of datasets related to people, including institutional censuses, health data systems, and human-resources fles. This data is sensitive, and its collection, sharing, and analysis require careful consideration. For instance, the European Union, through the General Data Protection Regulation (GDPR), protects the collection and processing of any personal data, including sexual orientation, ethnicity, and religion. Data visualization of sociodemographic data can reinforce stereotypes, marginalize groups, and lead to biased decision-making. It is, therefore, critical that these visualizations are created based on good, equitable design principles. In this paper, we discuss and provide a set of open research questions around the visualization of sociodemographic data. Our work contributes to an ongoing refection on representing data about people and highlights some important future research directions for the VIS community.

description: Electroweak precision observables, being highly sensitive to loop contributions of new physics, provide a powerful tool to test the theory and to discriminate between different models of the underlying physics. In that context, the $W$ boson mass, $M_W$, plays a crucial role. The accuracy of the $M_W$ measurement has been significantly improved over the last years, and further improvement of the experimental accuracy is expected from future LHC measurements. In order to fully exploit the precise experimental determination, an accurate theoretical prediction for $M_W$ in the Standard Model (SM) and extensions of it is of central importance. We present the currently most accurate prediction for the $W$ boson mass in the Next-to-Minimal Supersymmetric extension of the Standard Model (NMSSM), including the full one-loop result and all available higher-order corrections of SM and SUSY type. The evaluation of $M_W$ is performed in a flexible framework, which facilitates the extension to other models beyond the SM. We show numerical results for the $W$ boson mass in the NMSSM, focussing on phenomenologically interesting scenarios, in which the Higgs signal can be interpreted as the lightest or second lightest CP-even Higgs boson of the NMSSM. We find that, for both Higgs signal interpretations, the NMSSM $M_W$ prediction is well compatible with the measurement. We study the SUSY contributions to $M_W$ in detail and investigate in particular the genuine NMSSM effects from the Higgs and neutralino sectors.

description: Coherently driven atomic gases inside optical cavities hold great promise for generating rich dynamics and exotic states of matter. It was shown recently that an exotic topological superradiant state exists in a two-component degenerate Fermi gas coupled to a cavity, where local order parameters coexist with global topological invariants. In this work, we characterize in detail various properties of this exotic state, focusing on the feedback interactions between the atoms and the cavity field. In particular, we demonstrate that cavity-induced interband coupling plays a crucial role in inducing the topological phase transition between the conventional and topological superradiant states. We analyze the interesting signatures in the cavity field left by the closing and reopening of the atomic bulk gap across the topological phase boundary and discuss the robustness of the topological superradiant state by investigating the steady-state phase diagram under various conditions. Furthermore, we consider the interaction effect and discuss the interplay between the pairing order in atomic ensembles and the superradiance of the cavity mode. Our work provides many valuable insights into the unique cavity--atom hybrid system under study and is helpful for future experimental exploration of the topological superradiant state.

ECONOMIC VALUATION OF NECHISAR NATIONAL PARK ECOSYSYTEM: CHOICE EXPERIMENT APPROACH

Publisher: name: Zenodo
Year: 2016

description: Nechisar National Park is one of the known tourist attraction sites in Ethiopia due to its scenic land features, richness in diversified fauna and flora with some endemic mammals and birds. It was established in 1974 in the Southern Nation Nationality and Peoples of Ethiopia that is located 500kms from Addis Ababa, near Arba Minch town. But this rich ecosystem is endangered due to human encroachment. This is a result of a rapid expansion of Arba Minch town, the formation of state farms which latter privatized, establishment of various institutions, immigrants from the Gamo highlands and residents of Arba Minch town demanding forest production, illegal hunting and using the park for grazing by nearby communities. If the current conditions continue in such way the local community would lose any benefit that they may get from the ecosystem service of the park and the influx of tourists from various corners of the world. Hence, valuation is demanded to influence introduction of eco-tourism service by the stakeholders.

description: An analysis is given of the chromoelectric dipole moment of quarks and of the neutron in an MSSM extension where the matter sector contains an extra vectorlike generation of quarks and mirror quarks. The analysis includes contributions to the CEDM from the exchange of the $W$ and the $Z$ bosons, from the exchange of charginos and neutralinos and the gluino. Their contribution to the EDM of quarks is investigated. The interference between the MSSM sector and the new sector with vectorlike quarks is investigated. It is shown that inclusion of the vectorlike quarks can modify the quark EDMs in a significant way. Further, this interference also provides a probe of the vectorlike quark sector. These results are of interest as in the future measurements on the neutron EDM could see an improvement up to two orders of magnitude over the current experimental limits and provide a window to new physics beyond the standard model.

description: The School Breakfast Program (SBP) is a federally mandated program that has been shown to be associated with improved student test scores, behavior, attendance, and physical well-being. While free and reduced-eligible student qualify for both breakfast and lunch, breakfast participation consistently lags behind lunch consumption around the country. I spent 10 weeks at the Chapel Hill-Carrboro City Schools (CHCCS) Child Nutrition Department analyzing the breakfast program and understanding the challenges of delivering a quality school breakfast and encouraging widespread student participation. I investigated the Breakfast After the Bell program that sought to make breakfast at school more convenient and analyzed its impact on district breakfast participation. Additionally, I looked at recommendations for the district to push for equity in school breakfast while expanding its reach and participation numbers.

description: The Aharonov-Bohm (AB) cage enables localized confinement with nondiffractive propagation for arbitrary excitation. In this study, we introduce an anti-parity-time (anti-$\mathcal{PT}$) symmetric imaginary coupling in a generalized Creutz ladder to construct a non-Hermitian AB cage with tunable flat-band energy. We investigate compact localized states and complete localization dynamics, and show that non-Hermiticity affects the localization probability distributions and increases the oscillation period of the AB cage dynamics. Non-Hermitian engineering of the decoupled core of the AB cage is the essential point in our proposal. Our approach is widely applicable to a more general situation and can facilitate the manipulation of localization in physics.

description: In the last scene of our movie I took Carter to the Old Well where he had a superconscious experience upon drinking the water from the well, much like the movie from which we based our film, El Abrazo de la Serpiente. We created this scene because the legend says that the well water had abilities to give students a 4.0 GPA. Our movie changed from black and white to color as in the movie to further intensify the surreal experience that Carter had from drinking the water. Our movie depicted the class theme of belonging because many students drink from the Old Well out of superstition and to be a part of the campus culture.

description: With the development of wireless communication technologies which considerably contributed to the development of wireless sensor networks (WSN), we have witnessed an ever-increasing WSN based applications which induced a host of research activities in both academia and industry. Since most of the target WSN applications are very sensitive, security issue is one of the major challenges in the deployment of WSN. One of the important building blocks in securing WSN is key management. Traditional key management solutions developed for other networks are not suitable for WSN since WSN networks are resource (e.g. memory, computation, energy) limited. Key pre-distribution algorithms have recently evolved as efficient alternatives of key management in these networks. In the key pre-distribution systems, secure communication is achieved between a pair of nodes either by the existence of a key allowing for direct communication or by a chain of keys forming a key-path between the pair. In this paper, we propose methods which bring prior knowledge of network characteristics and application constraints into the design of key pre-distribution schemes, in order to provide better security and connectivity while requiring less resources. Our methods are based on casting the prior information as a graph. Motivated by this idea, we also propose a class of quasi-symmetric designs referred here to as g-designs. These produce key pre-distribution schemes that significantly improve upon the existing constructions based on unital designs. We give some examples, and point out open problems for future research.

description: Previous work (Glautier, 2013) showed that the responses made by humans on trial n in simple associative learning tasks were influenced by events that took place on trial n−1 and a simple extension of the Rescorla-Wagner Model (RWM Rescorla & Wagner, 1972), the Memory Environment Cue Array (MECA) model, was presented to account for those results. In the current work further evidence of non-local influences on responding during associative learning tasks is presented. The Rescorla-Wagner model and the MECA model are evaluated as models for the observed data using qualitative, näive maximum likelihood, and Akaike weight analyses. In two experiments the Akaike weight analyses strongly supported the simpler Rescorla-Wagner model over the MECA model but the qualitive and näive maximum likelihood analyses strongly supported the MECA model model over the simpler Rescorla-Wagner model. In Experiment 2 this apparent conflict was resolved using a generalisation criterion test (Ahn, Busemeyer, Wagenmakers, & Stout, 2008; Busemeyer & Wang, 2000) which gave clear support to the MECA model over the Rescorla-Wagner model. These results demonstrate the superiority of model selection using predictive validity, where possible, over selection using statistical adjustments for model complexity.

description: Suppose $K$ is a knot in $S^3$ with bridge number $n$ and bridge distance greater than $2n$. We show that there are at most ${2n\choose n}$ distinct minimal genus Heegaard splittings of $S^3\setminusη(K)$. These splittings can be divided into two families. Two splittings from the same family become equivalent after at most one stabilization. If $K$ has bridge distance at least $4n$, then two splittings from different families become equivalent only after $n-1$ stabilizations. Further, we construct representatives of the isotopy classes of the minimal tunnel systems for $K$ corresponding to these Heegaard surfaces.

description: Understanding how metal atoms are stabilized on metal oxide supports is important for predicting the stability of single-atom catalysts. In this study, we use scanning tunnelling microscopy (STM) and x-ray photoelectron spectroscopy (XPS) to investigate four catalytically active metals - Platinum, Rhodium, Nickel and Iridium - on the anatase TiO2(101) surface. The metals were vapor deposited at room temperature in ultrahigh vacuum (UHV) conditions, and also with a background water pressure of 2x10-8 mbar. Pt and Ni exist as a mixture of adatoms and nanoparticles in UHV at low coverage, with the adatoms immobilized at defect sites. Water has no discernible effect on the Pt dispersion, but significantly increases the amount of Ni single atoms. Ir is highly dispersed, but sinters to nanoparticles in the water vapor background leading to the formation of large clusters at step edges. Rh forms clusters on the terrace of anatase TiO2(101) irrespective of the environment. We conclude that introducing defect sites into metal oxide supports could be a strategy to aid the dispersion of single atoms on metal-oxide surfaces, and that the presence of water should be taken into account in the modelling of single-atom catalysts.

description: We consider expected utility maximisation problem for exponential Levy models and HARA utilities in presence of illiquid asset in portfolio. This illiquid asset is modelled by an option of European type on another risky asset which is correlated with the first one. Under some hypothesis on Levy processes, we give the expressions of information processes figured in maximum utility formula. As applications, we consider Black-Scholes models with correlated Brownian Motions, and also Black-Scholes models with jump part represented by Poisson process.

description: We produce and analyze eclipse time variation (ETV) curves for some 2600 Kepler binaries. We find good to excellent evidence for a third body in 222 systems via either the light-travel-time (LTTE) or dynamical effect delays. Approximately half of these systems have been discussed in previous work, while the rest are newly reported here. Via detailed analysis of the ETV curves using high-level analytic approximations, we are able to extract system masses and information about the three-dimensional characteristics of the triple for 62 systems which exhibit both LTTE and dynamical delays; for the remaining 160 systems we give improved LTTE solutions. New techniques of preprocessing the flux time series are applied to eliminate false positive triples and to enhance the ETV curves. The set of triples with outer orbital periods shorter than ~2000 days is now sufficiently numerous for meaningful statistical analysis. We find that (i) as predicted, there is a peak near i_m~40 deg in the distribution of the triple vs. inner binary mutual inclination angles that provides strong confirmation of the operation of Kozai-Lidov cycles with tidal friction; (ii) the median eccentricity of the third-body orbits is e_2=0.35; (iii) there is a deficit of triple systems with binary periods <1 day and outer periods between ~50 and 200 days which might help guide the refinement of theories of the formation and evolution of close binaries; and (iv) the substantial fraction of Kepler binaries which have third-body companions is consistent with a very large fraction of all binaries being part of triples.

Approximating Score-based Explanation Techniques Using Conformal Regression

description: Score-based explainable machine-learning techniques are often used to understand the logic behind black-box models. However, such explanation techniques are often computationally expensive, which limits their application in time-critical contexts. Therefore, we propose and investigate the use of computationally less costly regression models for approximating the output of score-based explanation techniques, such as SHAP. Moreover, validity guarantees for the approximated values are provided by the employed inductive conformal prediction framework. We propose several non-conformity measures designed to take the difficulty of approximating the explanations into account while keeping the computational cost low. We present results from a large-scale empirical investigation, in which the approximate explanations generated by our proposed models are evaluated with respect to efficiency (interval size). The results indicate that the proposed method can significantly improve execution time compared to the fast version of SHAP, TreeSHAP. The results also suggest that the proposed method can produce tight intervals, while providing validity guarantees. Moreover, the proposed approach allows for comparing explanations of different approximation methods and selecting a method based on how informative (tight) are the predicted intervals.

description: Making a movie was a very intriguing and fun. The scene I am focusing on is when Paola is in the library trying to print her paper. Our group decided to create this scene in order to depict the many setbacks that were faced during the journey in the film, El Norte. To create the movie, we set up the plot so that the goal was for Paola to turn in her paper, like the goal was to get to America in El Norte. Though the main characters endured struggles to achieve their goals, in the end, they weren’t completely successful.

Global $SU(3)_C\times SU(2)_L\times U(1)_Y$ linear sigma model: axial-vector Ward Takahashi identities, and decoupling of certain heavy BSM particles due to the Goldstone theorem

description: Dedicated to the memory of Raymond Stora (1930-2015). In the $SU(2)_L\times SU(2)_R$ Linear Sigma Model with PCAC, towers of Ward-Takahashi Identities (WTI) have long been known to give relations among 1-Scalar-Particle-Irreducible Green's functions, and among I- Scalar-Particle-Reducible T-Matrix elements, for external scalars (i.e. the Brout-Englert-Higgs scalar and 3 pseudoscalars). We extend these WTI and the resulting relations to the $SU(3)_C\times SU(2)_L\times U(1)_Y$ Linear Sigma Model including the heaviest generation of Standard Model (SM) fermions supplemented with the minimum necessary neutrino content -- right-handed neutrinos and Yukawa-coupling-induced Dirac neutrino mass. We extract powerful constraints on the effective Lagrangian: e.g. showing that they make separate tadpole renormalization unnecessary, and guarantee infra-red finiteness. Crucially, ultra-violet quadratic divergences (UVQD) and all other relevant operators contribute only to $m_π^2$, a Nambu-Goldstone boson (NGB) mass-squared. A WTI between T-Matrix elements (i.e. the Goldstone Theorem) then enforces $ m_π^2=0$ for the true NGB in the spontaneous symmetry breaking mode of the theory. All relevant operator contributions originating to all-loop-orders from virtual scalars, quarks and leptons, vanish identically! Our regularization-scheme-independent results are unchanged by the addition of certain heavy CP-conserving matter, such as originate in certain Beyond the SM models. We demonstrate this with two examples: a heavy singlet real scalar field with $Z_2$ symmetry and no VEV; and a heavy singlet right-handed Type I See-saw Majorana neutrino. Specifically, we prove that these heavy degrees of freedom decouple completely from the low-energy effective Lagrangian, contributing only irrelevant operators after quartic-coupling renormalization.
