“O, Zaria! You Have Become Just Like Karbala” : Race, Redemptive Suffering, and Affect in Shi‘i Devotional Liturgy

This article examines a Farsi-/Arabic-language Shi‘i ritual lamentation poem commemorating the Zaria Massacre of 2015, which saw hundreds of members of the Islamic Movement in Nigeria (IMN) led by Shaykh Ibrahim Zakzaky killed in clashes with the Nigerian army in the northern Nigerian city of Zaria, Kaduna Province. In addition to comparing the suffering of early-Muslim hagiographic figures with t

Cocoercivity, smoothness and bias in variance-reduced stochastic gradient methods

With the purpose of examining biased updates in variance-reduced stochastic gradient methods, we introduce SVAG, a SAG/SAGA-like method with adjustable bias. SVAG is analyzed in a cocoercive root-finding setting, a setting which yields the same results as in the usual smooth convex optimization setting for the ordinary proximal-gradient method. We show that the same is not true for SVAG when biase

High-throughput three-dimensional cellular platforms for screening biophysical microenvironmental signals

Cells in vivo are subjected continuously to multiple biochemical and biophysical stimuli from their microenvironment that regulate cell fate and function. Although two-dimensional (2D) platforms to check cell responses to various microenvironmental factors have been established, these methods lack physiological relevance. Macroscale three-dimensional (3D) cell culture platforms were developed to p

Pharmacometric covariate modeling using symbolic regression networks

A central challenge within pharmacometrics is to establish a relation between pharmacological model parameters, such as compartment volumes and diffusion rate constants, and known population covariates, such as age and body mass. There is rich literature dedicated to the learning of functional mappings from the covariates to the model parameters, once a search class of functions has been determine

Numerical investigation of the influence of the source and detector position for optical measurement of lung volume and oxygen content in preterm infants

There is an urgent need for improved respiratory surveillance of preterm infants. Gas in scattering media absorption spectroscopy (GASMAS) is emerging as a potential clinical cutaneous monitoring tool of lung functions in neonates. A challenge in the clinical translation of GASMAS is to obtain sufficiently high signal-to-noise ratios in the measurements, since the light attenuation is high in huma

A 3D-CFD Methodology for Combustion Modeling in Active Prechamber SI Engines Operating with Natural Gas

Active prechamber combustion systems for SI engines represent a feasible and effective solution in reducing fuel consumption and pollutant emissions for both marine and ground heavy-duty engines. However, reliable and low-cost numerical approaches need to be developed to support and speed-up their industrial design considering their geometry complexity and the involved multiple flow length scales.

Imaging of sugar-based contrast agents using their hydroxyl proton exchange properties

The ability of CEST MRI to detect the presence of millimolar concentrations of non-metallic contrast agents has made it possible to study, noninvasively, important biological molecules such as proteins and sugars, as well as drugs already approved for clinical use. Here, we review efforts to use sugar and sugar polymers as exogenous contrast agents, which is possible based on the exchange of their

Teacher Subject Knowledge, Didactic Skills, and Student Learning in Francophone Sub-Saharan Africa

We study the effects of two dimensions of teacher quality, subject knowledge and didactic skills, on student learning in francophone Sub-Saharan Africa. We use data from an international large- scale assessment in 14 countries that include individual-level information on student achievement and country-level measures of teacher subject knowledge and didactic skills in reading and math.

Energy transfer in multi-funnel systems quantitatively assessed by two-dimensional polarization imaging and single funnel approximation : From single molecules to ensembles

Two-dimensional polarization imaging (2D POLIM) is an experimental method where correlations between fluorescence excitation- and fluorescence emission-polarization properties are measured. One way to analyze 2D POLIM data is to apply a so-called single funnel approximation (SFA). The SFA allows for quantitative assessment of energy transfer between chromophores with identical spectra [homo-FRET (

Achromatic Cues Are Important for Flower Visibility to Hawkmoths and Other Insects

Studies on animal colour vision typically focus on the chromatic aspect of colour, which is related to the spectral distribution, and disregard the achromatic aspect, which is related to the intensity (“brightness”) of a stimulus. Although the chromatic component of vision is often most reliable for object recognition because it is fairly context independent, the achromatic component may provide a

Medborgerligt engagemang på sociala medier

Vi lever i en tid som präglas av sociala mediers växande betydelse inom en lång rad områden, inte minst när det gäller medborgerligt engagemang. I detta kapitel skissar vi en översiktsbild av olika sätt att tänka kring sociala medier och medborgerligt engagemang, och ger också en kort inblick i vad medborgarundersökningen berättar om engagemang på sociala medier. Medborgerligt engagemang i sociala

Combining semilocal exchange with dynamical mean-field theory : Electronic structure and optical response of rare-earth sesquioxides

In rare-earth semiconductors, wide ligand p and rare-earth 5d bands coexist with localized, partially filled 4f shells. A simultaneous description for both extended and localized states represents a significant challenge for first-principles theories. Here, we combine an ab initio dynamical mean-field theory approach to strong local correlations with a perturbative application of the semilocal mod

Design of a high-resolution Rayleigh-Taylor experiment with the Crystal Backlighter Imager on the National Ignition Facility

The Rayleigh-Taylor (RT) instability affects a vast range of High Energy Density (HED) length scales, spanning from supernova explosions (1013 m) to inertial confinement fusion (10-6 m). In inertial confinement fusion, the RT instability is known to induce mixing or turbulent transition, which in turn cools the hot spot and hinders ignition. The fine-scale features of the RT instability, which are
