Studies on sodium and potassium ion activated adenosine trihosphatase
Creators: name: Pang, Yew Choi
Publisher: name: University of British Columbia
Year: 2010

description: The Na⁺K⁺-activated ATPase was obtained from the rectal, glands of dog fish. Optimum conditions for extraction of the membrane bound enzyme into solution and stabilization by glycerol was investigated, followed by attempts to purify the enzyme by affinity chromatography using insolubilized Concanavalin A, wheat germ agglutinin and a modified ATP molecule as affinity ligands. The structure and size of the enzyme as a macromolecule was characterized by a combination of the results from velocity sedimentation in an isokinetic sucrose gradient and gel filtration with Sepharose 6B. The sedimentation coefficient was found to be 5.0 S by velocity sedimentation, and the Stokes' radius was found to be 114Å by gel filtration. Using these data, the molecular weight of the intact enzyme was estimated to be 240,000. This is in good agreement with the molecular weight derived from sodium dodecyl sulfate gel electrophoresis obtained by other workers.

description: We consider a quantum particle coupled (with strength $\la$) to a spatial array of independent non-interacting reservoirs in thermal states (heat baths). Under the assumption that the reservoir correlations decay exponentially in time, we prove that the long-time behavior of the particle is diffusive for small, but finite $\la$. Our proof relies on an expansion around the kinetic scaling limit ($\la \searrow 0$, while time and space scale as $\la^{-2}$) in which the particle satisfies a Boltzmann equation. We also show an equipartition theorem: the distribution of the kinetic energy of the particle tends to a Maxwell-Boltzmann distribution, up to a correction of $O(\la^2)$.

Year: 2010
Subjects: SECS-P/02 Politica economica

description: The present work provides an ex-post assessment of the UK 5-a-day information campaign where the positive effects of information on consumption levels are disentangled from the potentially conflicting price dynamics. 
A model-based estimate of the counterfactual (no-intervention) scenario is computed using data from the Expenditure and Food Survey between 2002 and 2006. For this purpose fruit and vegetable demand is modelled employing Quadratic Almost Ideal Demand System (QUAIDS) specification with demographic effects and controlling for  potential endogeneity of prices and total food expenditure.

description: The space of marked commutative rings on n given generators is a compact metrizable space. We compute the Cantor-Bendixson rank of any member of this space. For instance, the Cantor-Bendixson rank of the free commutative ring on n generators is omega^n, where omega is the smallest infinite ordinal. More generally, we work in the space of finitely generated modules over a given commutative ring.

Indicatori di correlazione e di disordine basati sul concetto di entropia
Creators: name: Bertozzi, Fabio <1965>
Publisher: name: Alma Mater Studiorum - Università di Bologna
Year: 2011
Subjects: SECS-S/01 Statistica

description: The aim of this work is to carry out  an applicative, comparative and  exhaustive study between several entropy based indicators of independence and correlation.
We considered some indicators characterized by a wide and consolidate literature, like mutual information, joint entropy, relative entropy or Kullback Leibler distance, and others, more recently introduced, like Granger, Maasoumi and racine entropy, also called Sρ, or utilized in more restricted domains, like Pincus approximate entropy or ApEn.
We studied the behaviour of such indicators applying them to binary series. The series was designed to simulate a wide range of situations in order to characterize indicators limit and capability and  to identify, case by case, the more useful and trustworthy ones.
Our target was not only to study if such indicators were able to discriminate between dependence and independence because, especially for mutual information and Granger, Maasoumi and Racine, that was already demonstrated and reported in literature, but also to verify if and how they were able to provide information about structure, complexity and disorder of the series they were applied to.
Special attention was paid on Pincus approximate entropy, that is said by the author to be able to provide information regarding  the level of randomness, regularity and complexity of a series.
By means of a focused and extensive research, we furthermore tried to clear the meaning of  ApEn applied to a couple of different series. In such situation the indicator is named in literature as cross-ApEn.
The cross-ApEn meaning and the interpretation of its results is often not simple nor univocal and the matter is scarcely delved into by literature, thereby users can easily leaded up to a misleading conclusion, especially if the indicator is employed, as often unfortunately it happens, in uncritical manner.
In order to plug some cross-ApEn gaps and limits clearly brought out during the experimentation, we  developed and applied to the already considered cases a further indicator we called “correspondence index”. The correspondence index is perfectly integrated into the cross-ApEn computational algorithm and it is able to provide, at least for binary data, accurate information about the intensity and the direction of an eventual correlation, even not linear, existing between two different series allowing, in the meanwhile, to detect an eventual condition of independence between the series themselves.

A study of some Di- and Tri-atomic halogen and interhalogen cations
Creators: name: Wilson, William Wayne
Publisher: name: University of British Columbia
Year: 2010

description: This study is primarily concerned with the cationic halogen derivatives iodine (I)- and bromine (I)- fluorosulfate, their structural and chemical properties, and their use as precursors in the formation of polyhalogen and polyinterhalogen cations. Infrared spectroscopy at 80°K is used to record the vibrational spectrum of IOSO₂F. A consistent assignment is presented for all halogen (I)- fluorosulfates, XOSO₂F where X = F, Cl, Br and I. Evidence for intermolecular association is found in the spectra of IOSO₂F and BrOSO₂F. The addition of diatomic halogens (I₂, Br₂, Cl₂) or interhalogens (IBr, ICI) to IOSO₂F results in the formation of polyhalogen and polyinterhalogen fluorosulfates according to the general reaction X₂ (XY) + IOSO₂F → IX₂SO₃F (IXYSO₃F); X,Y = I, Br and Cl. When the two compounds IX₂SO₃F and IY₂SO₃F are reacted together according to IX₂SO₃F + IY₂SO₃F → 2 IXYSO₃F; X,Y = I, Br and Cl; ligand redistribution occurs. Infrared and Raman spectra of these compounds are interpreted in terms of ionic structures consisting of the triatomic iodonium (III) cations I₃⁺, IBr₂⁺, ICl₂, IBrCl⁺, I₂Cl⁺ and I₂Br⁺ and the anion SO₃F⁻ with evidence for cation-anion interaction.

description: Humulus scandens (Lour.) Merr. este o specie alogenă invazivă recent introdusă (2019) în lista speciilor de îngrijorare pentru țările Uniunii Europene. Singurele semnalări din sudul Romȃniei (Muntenia) provin din împrejurimile Bucureștiului (1937) şi din localitatea Chirnogi, județul Călărași (2000). În urma cercetărilor de teren efectuate în anul 2021, în cadrul proiectului POIM/178/4/1/120008 „Managementul adecvat al speciilor invazive din România”, prezentăm noi date corologice ale speciei în regiunea Munteniei (Bazinul Hidrografic Argeș) și distribuția potențială în zona de sud a țării (Câmpia Română, văile din Dobrogea care se varsă în Dunăre și Delta Dunării). Pentru a defini distribuția potențială a speciei în zona de studiu a fost folosit un set de variabile spațiale relevante. Acestea au luat în considerare atât factori climatici, cât și factori topografici locali, pedologici, de impact antropic și de regim hidric. Pentru o imagine mai completă a distribuției actuale în zona de studiu, pe lângă punctele de prezență identificate în teren, am utilizat și date raportate în literatura de specialitate. Modelarea a fost prelucrată în software-ul R, cu pachetul SSDM, realizând un ansamblu care combină rezultatele mai multor modele, fiecare dintre acestea
 utilizând algoritmi de modelare diferiți. Performanța modelelor rezultate a fost evaluată conform Area Under Curve (AUC).
 Ansamblul de modele a înregistrat o abilitate predictivă bună (AUC > 0.85) și a sugerat faptul că distribuția speciei a fost influențată în cea mai mare măsură de textura solului și de distanța față de râuri. Rezultatele sunt în acord cu observațiile din teren, unde specia a fost mai abundentă în apropierea apei, dar cu un efectiv populațional redus în zonele mai uscate, relativ îndepărtate de apă. Sursa introducerii speciei Humulus scandens pe râurile Bazinului Hidrografic Argeș este necunoscută, dar specia necesită gestionare atentă din cauza caracterului său competitiv cu speciile native.

description: We discuss exact analytical solutions of a variety of statistical models recently obtained for finite systems by a novel powerful mathematical method, the Laplace-Fourier transform. Among them are a constrained version of the statistical multifragmentation model, the Gas of Bags Model and the Hills and Dales Model of surface partition. Thus, the Laplace-Fourier transform allows one to study the nuclear matter equation of state, the equation of state of hadronic and quark gluon matter and surface partitions on the same footing. A complete analysis of the isobaric partition singularities of these models is done for finite systems. The developed formalism allows us, for the first time, to exactly define the finite volume analogs of gaseous, liquid and mixed phases of these models from the first principles of statistical mechanics and demonstrate the pitfalls of earlier works. The found solutions may be used for building up a new theoretical apparatus to rigorously study phase transitions in finite systems. The strategic directions of future research opened by these exact results are also discussed.

Swift observations of the very intense flaring activity of Mrk 421 during 2006: I. Phenomenological picture of electron acceleration and predictions for the MeV/GeV emission

description: We present results from a deep spectral analysis of all the Swift observations of Mrk 421 from April 2006 to July 2006, when it reached its largest X-ray flux recorded until 2006. The peak flux was about 85 milli-Crab in the 2.0-10.0 keV band, with the peak energy (Ep) of the spectral energy distribution (SED) laying often at energies larger than 10 keV. We performed spectral analysis of the Swift observations investigating the trends of the spectral parameters in terms of acceleration and energetic features phenomenologically linked to the SSC model parameters, predicting their effects in the gamma-ray band, in particular the spectral shape expected in the Fermi Gamma-ray Space Telescope-LAT band. We confirm that the X-ray spectrum is well described by a log-parabolic distribution close to Ep, with the peak flux of the SED (Sp) being correlated with Ep, and Ep anti-correlated with the curvature parameter (b). During the most energetic flares the UV-to-soft-X-ray spectral shape requires an electron distribution spectral index s about 2.3. Present analysis shows that the UV-to-X-ray emission from Mrk 421 is likely to be originated by a population of electrons that is actually curved, with a low energy power-law tail. The observed spectral curvature is consistent both with stochastic acceleration or energy dependent acceleration probability mechanisms, whereas the power-law slope form XRT-UVOT data is very close to that inferred from the GRBs X-ray afterglow and in agreement with the universal first-order relativistic shock acceleration models. This scenario hints that the magnetic turbulence may play a twofold role: spatial diffusion relevant to the first order process and momentum diffusion relevant to the second order process.

description: Contradicting results have been reported in the literature with respect to the performance of the numerical techniques employed for the study of supersonic turbulence. We aim at characterising the performance of different particle-based and grid-based techniques on the modelling of decaying supersonic turbulence. Four different grid codes (ENZO, FLASH, TVD, ZEUS) and three different SPH codes (GADGET, PHANTOM, VINE) are compared. We additionally analysed two calculations denoted as PHANTOM A and PHANTOM B using two different implementations of artificial viscosity. Our analysis indicates that grid codes tend to be less dissipative than SPH codes, though details of the techniques used can make large differences in both cases. For example, the Morris & Monaghan viscosity implementation for SPH results in less dissipation (PHANTOM B and VINE versus GADGET and PHANTOM A). For grid codes, using a smaller diffusion parameter leads to less dissipation, but results in a larger bottleneck effect (our ENZO versus FLASH runs). As a general result, we find that by using a similar number of resolution elements N for each spatial direction means that all codes (both grid-based and particle-based) show encouraging similarity of all statistical quantities for isotropic supersonic turbulence on spatial scales k

Publisher: name: arXiv

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Understanding the behaviour of linear waves on black hole backgrounds is a central problem in general relativity, intimately connected with the nonlinear stability of the black hole spacetimes themselves as solutions to the Einstein equations--a major open question in the subject. Nonetheless, it is only very recently that even the most basic boundedness and quantitative decay properties of linear waves have been proven in a suitably general class of black hole exterior spacetimes. This talk will review our current mathematical understanding of waves on black hole backgrounds, beginning with the classical boundedness theorem of Kay and Wald on exactly Schwarzschild exteriors and ending with very recent boundedness and decay theorems (proven in collaboration with Igor Rodnianski) on a wider class of spacetimes. This class of spacetimes includes in particular slowly rotating Kerr spacetimes, but in the case of the boundedness theorem is in fact much larger, encompassing general axisymmetric stationary spacetimes whose geometry is sufficiently close to Schwarzschild and whose Killing fields span the null generator of the horizon.

description: Medicaid presently insures about one-fourth of the US population and disproportionately insures about thirty eight percent of non-elderly adults with an opioid use disorder (OUD). Owing to Medicaid’s prominent role insuring persons with an OUD and that Medicaid coverage includes pharmaceutical benefits, there has been considerable interest in studying potential prescription opioid misuse among Medicaid beneficiaries and identifying subpopulations at higher risk for misuse and possible progression to an OUD. Study goals were to explore the associations among prescription opioid misuse, OUD, and co-occurring mental health and other substance use disorders (SUD). We analyzed Illinois Medicaid 2018 claims data for 1,102,479 adult beneficiaries 18 to 64 years of age. Using algorithms based on previous studies, we first determined the presence or absence of nine SUDS (including OUD) as well as nine mental health disorders and likely prescription opioid misuse. We then subdivided the beneficiary sample into five groups: those who were prescribed opioids and evidenced either no, possible, or probable misuse; those evidencing an OUD; and those evidencing no opioid use or misuse. Bivariate analyses, upset plots, and multinomial logistic regressions were used to compare the five subgroups on the prevalence of co-occurring SUDS and mental health disorders. Those with an OUD or with probable prescription opioid misuse had the highest prevalences of most co-occurring conditions with beneficiaries with an OUD the most likely to evidence co-occurring SUDS, particularly tobacco use disorder, whereas those with probable misuse had elevated prevalence rates of co-occurring mental health disorders comparable to those with an OUD. The medical complexity of persons with an OUD or misusing prescription opioids are considered in light of recent attempts to expand buprenorphine provision as medication assisted treatment among Medicaid beneficiaries. We also consider the possibility co-occurring mental health disorders and tobacco use disorder as important risk factors for progressing to prescription opioid misuse and an OUD.
Storm flows of the Lower Fraser Valley
Creators: name: Taylor, John W.
Publisher: name: University of British Columbia
Year: 2010

description: Unit hydrographs are derived for four watersheds in the Lower Fraser Valley using a computerized least squares technique. These unit hydrographs are then related to specific basin characteristics so that synthetic unit hydrographs can be constructed for the ungauged basins in the area. After attempting several techniques to relate the unit hydrographs to basin characteristics both the time-to-peak and the peak flow were related to the basin slope, shape, channel length and degree of urbanization. To more fully define the synthetic unit hydrograph shape, the unit hydrograph widths at 50 per cent and 75 per cent of the peak flow were related to the peak flow. In this way five points can be used to establish the unit hydrograph shape (one for the peak and four for the widths). Other results included estimates of average infiltration rates for each basin calculated from rainfall and runoff data.

description: We derive the sampling probability density function (pdf) of an ideal localized random electromagnetic field, its amplitude and intensity in an electromagnetic environment that is quasi-statically time-varying statistically homogeneous or static statistically inhomogeneous. The results allow for the estimation of field statistics and confidence intervals when a single spatial or temporal stochastic process produces randomization of the field. Results for both coherent and incoherent detection techniques are derived, for Cartesian, planar and full-vectorial fields. We show that the functional form of the sampling pdf depends on whether the random variable is dimensioned (e.g., the sampled electric field proper) or is expressed in dimensionless standardized or normalized form (e.g., the sampled electric field divided by its sampled standard deviation). For dimensioned quantities, the electric field, its amplitude and intensity exhibit different types of Bessel $K$ sampling pdfs, which differ significantly from the asymptotic Gauss normal and $χ^{(2)}_{2p}$ ensemble pdfs when $ν$ is relatively small. By contrast, for the corresponding standardized quantities, Student $t$, Fisher-Snedecor $F$ and root-$F$ sampling pdfs are obtained that exhibit heavier tails than comparable Bessel $K$ pdfs. Statistical uncertainties obtained from classical small-sample theory for dimensionless quantities are shown to be overestimated compared to dimensioned quantities. Differences in the sampling pdfs arising from de-normalization versus de-standardization are obtained.

description: The configuration-fixed deformation constrained relativistic mean field approach with time-odd component has been applied to investigate the ground-state properties of $^{33}$Mg with effective interaction PK1. The ground state of $^{33}$Mg has been found to be prolate deformed, $β_2=0.23$, with the odd neutron in $1/2[330]$ orbital and the energy -251.85 MeV which is close to the data -252.06 MeV. The magnetic moment $- 0.9134 μ_\mathrm{N}$ is obtained with the effective electromagnetic current which well reproduces the data $- 0.7456 μ_\mathrm{N}$ self-consistently without introducing any parameter. The energy splittings of time reversal conjugate states, the neutron current, the energy contribution from the nuclear magnetic potential, and the effect of core polarization are discussed in detail.

Poiché gli interpreti professionisti coinvolti hanno lavorato dalla lingua straniera alla loro lingua materna e viceversa, il fattore direzionalità è il parametro di analisi delle prestazioni degli interpreti secondo i metodi di indagine della linguistica dei corpora.

In this doctoral thesis a methodology was developed to fully apply the corpus-based approach to simultaneous interpreting research. DIRSI-C is a parallel (Italian-English/English-Italian) and aligned electronic corpus, containing transcripts of recorded medical international conferences with professional simultaneous interpreters working both from and into their foreign language. Against this backdrop, directionality represents the research parameter used to analyze interpreters' performance by means of corpus linguistics tools.

Esse esforço é justificado pelo apoio que tais ferramentas provêm à compreensão do aluno, ao abordar temas onde o objeto de reflexão é isolado de fatores comuns à sua realidade. Para seu desenvolvimento, foi utilizado HTML5, por se tratar de uma linguagem de código aberto e de uso mais acessível.  “Transmission Versus Propagation Delay”, do Kurose, foi o aplicativo escolhido para ser trabalhado. O mesmo é indicado no livro “Internet e Redes de Computadores” e seu objetivo é ilustrar a diferença entre os atrasos de transmissão e propagação que ocorrem durante o envio de pacotes em uma rede de computadores. Inicialmente o aplicativo pretende benefíciar os alunos das disciplina Redes I do Curso Superior de Tecnologia em Análise e Desenvolvimento de Sistemas da FAETERJ-Rio/FAETEC, podendo o mesmo ser utilizado por alunos de qualquer nível de escolaridade, sob orientação do educador.

description: The global food demand is expected to increase in the coming years, along with challenges around climate change and food security. Concomitantly, food safety risks, particularly those related to bacterial pathogens, may also increase. Thus, the food sector needs to innovate to rise to this challenge. Here, we discuss recent advancements in molecular techniques that can be deployed within various foodborne bacteria surveillance systems across food settings. To start with, we provide updates on nucleic acid-based detection, with a focus on polymerase chain reaction (PCR)-based technologies and loop-mediated isothermal amplification (LAMP). These include descriptions of novel genetic markers for several foodborne bacteria and progresses in multiplex PCR and droplet digital PCR. The next section provides an overview of the development of clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated (Cas) proteins systems, such as CRISPR-Cas9, CRISPR-Cas12a, and CRISPRCas13a, as tools for enhanced sensitive and specific detection of foodborne pathogens. The final section describes utilizations of whole genome sequencing for accurate characterization of foodborne bacteria, ranging from epidemiological surveillance tomodel-based predictions of bacterial phenotypic traits through genome-wide association studies or machine learning.

Modeling the cosmological co-evolution of supermassive black holes and galaxies

description: In this Thesis, we investigate the cosmological co-evolution of supermassive black holes (BHs), Active Galactic Nuclei (AGN) and their hosting dark matter (DM) halos and galaxies, within the standard CDM scenario. We  analyze both analytic, semi-analytic and hybrid techniques and use the most
recent observational data available to constrain the assumptions underlying our models. First, we focus on very simple analytic models where the assembly of BHs is directly related to the merger history of DM haloes. For this
purpose, we implement the two original analytic models of Wyithe & Loeb 2002 and Wyithe & Loeb 2003, compare their predictions to the AGN luminosity function and clustering data, and discuss possible modifications to
the models that improve the match to the observation. Then we study more sophisticated semi-analytic models in which however the baryonic physics is neglected as well. Finally we improve the hybrid simulation of De Lucia & Blaizot 2007, adding new semi-analytical prescriptions to describe the BH
mass accretion rate during each merger event and its conversion into radiation, and compare the derived BH scaling relations, fundamental plane and mass function, and the AGN luminosity function with observations.
All our results support the following scenario:
• The cosmological co-evolution of BHs, AGN and galaxies can be well
described within the CDM model.
• At redshifts z & 1, the evolution history of DM halo fully determines the overall properties of the BH and AGN populations. The AGN emission is triggered mainly by DM halo major mergers and, on average, AGN shine at their Eddington luminosity.
• At redshifts z . 1, BH growth decouples from halo growth. Galaxy major mergers cannot constitute the only trigger to accretion episodes in this phase.
• When a static hot halo has formed around a galaxy, a fraction of the hot gas continuously accretes onto the central BH, causing a low-energy “radio” activity at the galactic centre, which prevents significant gas
cooling and thus limiting the mass of the central galaxies and quenching the star formation at late time.
• The cold gas fraction accreted by BHs at high redshifts seems to be larger than at low redshifts.

Quantum Mechanics Of Consciousness

description: A phenomenological approach using the states of spin-like observables is developed to understand the nature of consciousness and the totality of experience. The three states of consciousness are taken to form the triplet of eigenstates of a spin-one entity and are derived as the triplet resulting from the composition of two spins by treating the subject and the object as interacting two-state, spin-half systems with external and internal projections. The state of deep sleep is analysed in the light of this phenomenological approach and a novel understanding of the status of the individual consciousness in this state is obtained. The resulting fourth state i.e. the singlet state is interpreted to correspond to the superconscious state of intuitive experience and is justified by invoking the concept of the universal consciousness as the underlying source of all individual states of experience. It is proposed that the individual experiences result from the operations of four individualizing observables which project out the individual from the universal. The one-to-one correspondence between the individual and the universal states of experience is brought out and their identity in the fourth state is established by showing that all individualizing quantum numbers become zero in this state leaving no trace of any individuality.

Socioeconomic and situational factors in urban traffic noise annoyance levels
Creators: name: Saur, William Leonard

description: Traffic noise is having an increasingly adverse impact on the quality of urban life. As a result it is necessary for community planners and engineers to develop better traffic management criteria and study techniques to keep the level of community traffic noise to socially desirable levels. In the recent past substantial research has been done to help understand the physical properties of traffic noise and indices of community noise perception. However, little is understood about the perception and annoyance levels of specific groups toward traffic noise. Complete knowledge of all dimensions of traffic noise annoyance is necessary for the further development of community traffic management criteria and neighborhood planning techniques. The purpose of this research is to investigate the dimensions of public annoyance to traffic noise in a large city. Specifically, the study objective is to investigate the relationship between noise annoyance in several urban neighborhoods and the socioeconomic and situational variables which have some impact on attitudes about traffic noise. Following a preliminary noise annoyance survey of 3500 households in Vancouver, British Columbia, a discriminant-classification statistical technique was used to analyze a follow-up, in depth, attitudinal survey of 331 households in several neighborhoods. Three categories of information were obtained in the survey: 1) a household survey of attitudes to noise using a semantic differential scaling technique; 2) measures of the socioeconomic and cultural profiles of each household surveyed, and 3) measures of the physical and situational neighborhood variables which would likely have some effect on the noise environment of the household. The statistical model was used to investigate the dimensions of socioeconomic, cultural, and physical variables on separating those social groupings which were highly sensitive to traffic noise from those who were less sensitive. Results show that the respondent's high socioeconomic status is the major factor in noise annoyance followed by the distance the respondent lives from major traffic arteries. Particularly, it appears that education levels are the dominant factor in traffic noise annoyance. The implication of the results of this research is that traffic management criteria must include consideration of the socioeconomic and cultural environment as well as accepted traffic planning criteria to meet publicly acceptable traffic noise levels.

description: The risk of secondary infection with SARS-CoV-2 and influenza A virus is becoming a practical problem that must be addressed as the flu season merges with the COVID-19 pandemic. As SARS-CoV-2 and influenza A virus have been found in patients, understanding the in vivo characteristics of the secondary infection between these two viruses is a high priority. Here, hACE2 transgenic mice were challenged with the H1N1 virus at a nonlethal dose during the convalescent stage on 7 and 14 days post SARS-CoV-2 infection, and importantly, subsequent H1N1 infection showed enhanced viral shedding and virus tissue distribution. Histopathological observation revealed an extensive pathological change in the lungs related to H1N1 infection in mice recovered from SARS-CoV-2 infection, with severe inflammation infiltration and bronchiole disruption. Moreover, upon H1N1 exposure on 7 and 14 dpi of SARS-CoV-2 infection, the lymphocyte population activated at a lower level with T cell suppressed in both PBMC and lung. These findings will be valuable for evaluating antiviral therapeutics and vaccines as well as guiding public health work.

description: Deploying scientific computing software for high performance computing (HPC) systems has become increasingly challenging with the rapid growth of the HPC software stack to accommodate a variety of application needs to exploit ever-increasing computing system capability. Under the leadership of the DOE Exascale Computing Project (ECP), this problem has been addressed through (1) the development of a software package management framework (Spack) and (2) the investigation of container platforms to improve the software building and installation process. Along with these software technologies, the ECP has been establishing a sustainable software ecosystem for HPC software stack, introducing suites of pre-build software collections and new community policies to advocate stable software building, testing and documenting practices for improving the software quality and the interoperability between them.
This short whitepaper examines the problem and suggests solutions by standardizing and improving modern CMake.
