description: In this work we investigate the phenomena associated with the new thresholds in the spectrum of excitations arising when different one-dimensional strongly interacting systems are voltage biased and weakly coupled by tunneling. We develop the perturbation theory with respect to tunneling and derive an asymptotic behavior of physical quantities close to threshold energies. We reproduce earlier results for the electron relaxation at the edge of an integer quantum Hall system and for the non-equilibrium Fermi edge singularity phenomenon. In contrast to the previous works, our analysis does not rely on the free-fermionic character of local tunneling, therefore we are able to extend our theory to wider class of systems, without well-defined electron excitations, such as spinless Luttinger liquids and chiral quantum Hall edge states at fractional filling factors.

description: Spatial variations of the average properties that characterize the hadronic component of the diffuse Galactic cosmic-ray sea, in particular the spectral slope and normalization, may unveil critical information about their confinement mechanism in the Galaxy. In the first part of this paper we perform an analysis of the Fermi-LAT gamma-ray data with the SkyFACT package, which combines image reconstruction techniques with standard template fitting, isolate the hadronic emission and decompose it into Galactocentric rings. We find a significant hardening of the hadronic spectral index towards the molecular ring. We study this hardening in different energy ranges, and assess its resilience with respect to different prescriptions in the analysis setup. In the second part we quantify the contribution to the diffuse gamma-ray flux coming from unresolved point sources with a dedicated Monte Carlo simulation, and consider whether the trend characterized in the first part can be mimicked by a progressively more relevant flux associated to this component in the inner Galaxy. We find that the observed hardening of the hadronic spectral index cannot be due to unresolved sources in the sub-TeV energy range, especially outside the molecular ring, given reasonable assumptions about the unresolved source population.

description: In this work, the formation of ternary complexes with their respective formation constants in the systems formed by copper (II), 2,6-pyridinedicarboxylic acid (H2Dipi) and the amino acids = histidine (His), aspartic acid (H2Asp), glutamic acid (H2Glu), glycine (HGly), proline (HPro), α-alanine (HαAla), β-alanine (HβAla), serine (HSer), threonine (HThr), phenylalanine (HPhe) and methionine (HMet)). The analysis used potentiometric data analysed with the least-squares program LETAGROP in aqueous solution at 25°C in 1.0 mol.dm−3 KNO3 solution. The relative stability of the ternary complexes is compared with the binary ones using the values of Δlog K and log χ. Subsequently, by using the formation constants, the species distribution diagrams were generated and are briefly discussed here. The Cu (II) -dipicolinic acid-glutamic acid, Cu (II) -dipicolinic acid-glycine and Cu (II) – dipicolinic acid-histidine systems were characterised by UV-Vis molecular absorption spectroscopy and cyclic voltammetry, confirming the formation of ternary complexes with octahedral geometry.

description: We present a new class of sequential adsorption models in which the adsorbing particles reach the surface following an inclined direction (shadow models). Capillary electrophoresis, adsorption in the presence of a shear or on an inclined substrate are physical manifestations of these models. Numerical simulations are carried out to show how the new adsorption mechanisms are responsible for the formation of more ordered adsorbed layers and have important implications in the kinetics, in particular modifying the jamming limit.

description: “Sorry Ecology” is a collection of poems in which I explore the relationship between desire and loss through ecological, domestic, communal, and spiritual routes. I have rendered the poems through a lyric “I,” an “I” that often uses “we,” that inhabits worlds both real and imagined, personal and shared. Throughout the manuscript, water becomes a motif to consider movement and travel, the instability of place, grief, and the ways in which desire’s limits are forever out of focus, unattainable. The poems are interested in substance and lack of substance, place and no place. The space created by the poems of this manuscript is ultimately one that interrogates and explores the nature of relationships.

On the Ambiguity of Machine Learning Exception Symptoms: Insights from Stack Overflow Posts
Creators: name: Anonymous, Anonymous
Publisher: name: Zenodo
Year: 2024

description: Software stack traces are a primary source of information for developers that aim to correct erroneous software behavior. While Machine Learning (ML) applications can also produce stack traces, their stack traces are the object of few studies. In this paper, we seek to examine the reported symptoms of exceptions and assess their impact on community support in resolving failures. Our study uses seven popular ML libraries on Stack Overflow (SO). Our focus extends beyond call stacks to contain the additional aspects of exceptions, specifically the exception type and error message. This study reveals the distribution of ML exception symptoms on SO, highlighting that approximately half of the questions that include stack traces involve all three symptoms, while others feature specific combinations. The exploration of symptom ambiguity indicates that individual error message templates or exception types do not definitively identify ML exception-related questions. Notably, questions solely featuring call stack symptoms are less likely to receive prompt community support. However, incorporating exception types and error messages alongside call stacks enhances the likelihood and speed of obtaining accepted answers.

description: Blazars are known for their energetic multiwavelength flares from radio wavelengths to high-energy $γ$-rays. In this work, we study radio, optical, and $γ$-ray light curves of 145 bright blazars spanning up to 8~yr, to probe the flaring activity and interband correlations. Of these, 105 show $>1σ$ correlations between one or more wavebands, 26 of which have a $>3σ$ correlation in at least one wavelength pair, as measured by the discrete correlation function. The most common and strongest correlations are found between the optical and $γ$-ray bands, with fluctuations simultaneous within our $\sim 30$~d resolution. The radio response is usually substantially delayed with respect to the other wavelengths with median time lags of $\sim 100$--160~d. A systematic flare identification via Bayesian block analysis provides us with a first uniform sample of flares in the three bands, allowing us to characterise the relative rates of multiband and "orphan" flares. Multiband flares tend to have higher amplitudes than "orphan" flares.

title: Urban Health in Medieval Canterbury: An Osteoarchaeological Examination of Health Outcomes
Creators: name: White, Thomasina
Publisher: name: University of Kent
Year: 2024

description: The sacred city of Canterbury was a renowned theological centre during the medieval period (11th to 15th century). It attracted numerous pilgrims with the hopes of gaining miracles from the spirits of saints. Thus, this influenced the people of Canterbury to make a profit off the pilgrims, ultimately influencing the urban centre. The social environment, such as social status, behaviours, and ideologies, impacts urban health. The physical environment, such as dense housing conditions, inadequate food supply, unhygienic disposal of waste, and adverse weather conditions, have negatively impacted urban health in medieval England. Previous biological anthropological studies on medieval Canterbury focused on pathological cases, biorhythms, maturation, enamel microevolution, and behaviour from bone histology. Little is known about the effects of the urban environment on the population’s health; therefore, this research examines urban health in medieval Canterbury. A macroscopic analysis of individuals from St. Gregory's Priory (11th to early 16th century) skeletal collection was conducted for this study. Childhood growth, survivorship and mortality risk patterns were selected to assess non-adults' health. Raunds (Raunds Furnells), Newcastle (Black Gate), and York (All Saint's Church) skeletal collections were also analysed for childhood growth to identify similar and different urban and rural health outcomes. For the health of adults, pathological conditions (periosteal new bone formation and cribra orbitalia as a proxy for parasitic infections), and survivorship and mortality risk patterns were assessed. The findings indicate that non-adults from Canterbury (from birth to 3 years and 4 years and older) had a lower risk of delayed tibial and femoral diaphyseal growth compared to those from Newcastle. Contrarily, there are no significant differences between the risk of delayed femoral and tibial diaphyseal growth of non-adults from Canterbury and Raunds from birth to 3 years and 4 years and older. On the other hand, the risk of delayed femoral and tibial diaphyseal growth of non-adults 4 years and older from Canterbury is lower than those from Raunds. In addition, non-adults from Canterbury (from birth to 3 years and 4 years and older) had a lower risk of delayed femoral diaphyseal growth compared to those from York. Also, there is no significant difference between high- and low-status adults with parasitic infections. Additionally, Low-status non-adults had increased survivorship compared to high-status nonadults. Similarly, low-status adult males had increased survivorship and lower mortality risk compared to high-status adult females. Urban health in medieval Canterbury was significantly influenced by the pilgrimage culture, breastfeeding and weaning practices, dense housing conditions, polluted water resources, inadequate sanitation, and dietary intake.

description: IMPORTANCE: Childhood obesity is the focus of public health efforts and accurate estimates of the prevalence and severity of obesity are needed for policy decisions and directions for future research.

OBJECTIVE: To examine the prevalence of obesity and severe obesity over time for 14 years of the continuous National Health and Nutrition Examination Survey, 1999 to 2012, and to examine differences in the trends by age, race/ethnicity, and sex.

DESIGN, SETTING, AND PARTICIPANTS: Representative sample (N = 26 690) of children in the United States, ages 2 to 19 years, in repeated cross-sections of the National Health and Nutrition Examination Survey, 1999 to 2012.

MAIN OUTCOMES AND MEASURES: Prevalence of overweight (body mass index [BMI] ≥ 85th percentile), obesity (BMI ≥ 95th percentile for age and sex), class 2 obesity (BMI ≥ 120% of the 95th percentile or BMI ≥ 35), and class 3 obesity (BMI ≥ 140% of the 95th percentile or BMI ≥ 40).

RESULTS: From 2011 to 2012, 17.3% (95% CI, 15.3-19.3) of children in the United States aged 2 to 19 years were obese. Additionally, 5.9% (95% CI, 4.4-7.4) of children met criteria for class 2 obesity and 2.1% (95% CI, 1.6-2.7) met criteria for class 3 obesity. Although these rates were not significantly different from 2009 to 2010, all classes of obesity have increased over the last 14 years.

CONCLUSIONS AND RELEVANCE: Nationally representative data do not show any significant changes in obesity prevalence in the most recently available years, although the prevalence of obesity may be stabilizing. Continuing research is needed to determine which, if any, public health interventions can be credited with this stability. Unfortunately, there is an upward trend of more severe forms of obesity and further investigations into the causes of and solutions to this problem are needed.
Fermi Constants and ``New Physics''

description: Various precision determinations of the Fermi constant are compared. Included are muon and (leptonic) tau decays as well as indirect prescriptions employing $α, m_Z, m_W, \ssthwmzms, Γ(Z\to\ell^+\ell^-)$, and $Γ(Z \to ν\bar ν)$ as input. Their good agreement tests the standard model at the $\pm 0.1%$ level and provides stringent constraints on new physics. That utility is illustrated for: heavy neutrino mixing, 2 Higgs doublet models, S, T, and U parameters and excited $W^{\ast^\pm}$ bosons (Kaluza-Klein excitations). For the last of those examples, $m_{W^\ast}\gsims 2.9$ TeV is found.

Parabolic Compactification of Homogeneous Spaces

description: In this article, we study compactifications of homogeneous spaces coming from equivariant, open embeddings into a generalized flag manifold $G/P$. The key to this approach is that in each case $G/P$ is the homogeneous model for a parabolic geometry; the theory of such geometries provides a large supply of geometric tools and invariant differential operators that can be used for this study. A classical theorem of J.~Wolf shows that any involutive automorphism of a semisimple Lie group $G$ with fixed point group $H$ gives rise to a large family of such compactifications of homogeneous spaces of $H$. Most examples of (classical) Riemannian symmetric spaces as well as many non--symmetric examples arise in this way. A specific feature of the approach is that any compactification of that type comes with the notion of "curved analog" to which the tools we develop also apply. The model example of this is a general Poincaré--Einstein manifold forming the curved analog of the conformal compactification of hyperbolic space. In the first part of the article, we derive general tools for the analysis of such compactifications. In the second part, we analyze two families of examples in detail, which in particular contain compactifications of the symmetric spaces $SL(n,\Bbb R)/SO(p,n-p)$ and $SO(n,\Bbb C)/SO(n)$. We describe the decomposition of the compactification into orbits, show how orbit closures can be described as the zero sets of smooth solutions to certain invariant differential operators and prove a local slice theorem around each orbit in these examples.

Distinction of atmospheric neutrino-mu - neutrino-tau and neutrino-mu - neutrino-sterile oscillations using short or intermediate baseline experiments

Year: 1998
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The current case for atmospheric $ν_μ$ oscillations into active or sterile neutrinos is reviewed. It is argued that neither the study of neutral current events at Super-Kamiokande, nor the information obtained from future long baseline experiments might be sufficient to unambigously decide between these two scenarios. However, a combination of these results with the results from future short or intermediate baseline $τ$ appearance experiments would clearly resolve most of the remaining ambiguities. This conclusion does not strongly depend on whether the results from LSND will be confirmed or not. In the case that LSND would be confirmed, a negative result in such a short or intermediate baseline experiment would also unambigously exclude the interpretation of LSND as indirect $ν_μ-ν_τ-ν_e$ oscillations.

A considerable cut-off dependence can be seen in comparison with earlier determinations from tree level Symanzik and tadpole improved actions.

description: The maintenance process shares significant operating costs in an organisation. Lean thinking can be incorporated into maintenance activities through applying its principles and practices/tools. Lean maintenance (LM) is a prerequisite for lean manufacturing systems. This research proposes a new structure for LM process based on a systematic literature review of a significant number of related articles that were published on LM. The process structure is designed based on the five lean principles to guide and support organisations to pursue maintenance excellence. This study establishes a scheme for LM tools that are structured into 2 level 4 bundles and 26 lean practices/tools and develops a House of Waste (HoW) to demonstrate the association between maintenance wastes and the LM tools. With a successful accomplishment of the proposed scheme, the performance of a maintenance department can create more improvement opportunities over time to reach the maintenance excellence status.

description: We present the first results from a study of OVI absorption around galaxies at $z<1.44$ using data from a near-infrared grism spectroscopic Hubble Space Telescope Large Program, the Quasar Sightline and Galaxy Evolution (QSAGE) survey. QSAGE is the first grism galaxy survey to focus on the circumgalactic medium at $z\sim1$, providing a blind survey of the galaxy population. Using the first of 12 fields, we provide details of the reduction methods, in particular the handling of the deep grism data which uses multiple position angles to minimise the effects of contamination from overlapping traces. The resulting galaxy sample is H$α$ flux limited ($f({\rm Hα}) > 2\times10^{-17}$ erg s$^{-1}$ cm$^{-2}$) at 0.680.68, we find 5 OVI absorption systems along the line of sight with identified galaxies lying at impact parameters of $b\approx100-350$ kpc (proper), whilst we find a further 13 galaxies with no significant associated OVI absorption (i.e. $N({\rm OVI})<10^{13.5-14}$ cm$^{-2}$) in the same impact parameter and redshift range. We find a large scatter in the stellar mass and star-formation rates of the closest galaxies with associated OVI. Whilst one of the OVI absorber systems is found to be associated with a low mass galaxy group at $z\approx1.08$, we infer that the detected OVI absorbers typically lie in the proximity of dark matter halos of masses $10^{11.5} {\rm M_\odot}\lesssim M_{\rm halo}\lesssim10^{12} {\rm M_\odot}$.

Subjects: subject: Control Theory
subject: Event-triggered Control
subject: Lyapunov Theory

description: This paper revisits the classical multi-agent average consensus problem for which many different event-triggered control strategies have been proposed over the last decade. Many of the earliest versions of these works conclude asymptotic stability without proving that Zeno behavior, or deadlocks, do not occur along the trajectories of the system. More recent works that resolve this issue either: (i) propose the use of a dwell-time that forces inter-event times to be lower-bounded away from zero but sacrifice asymptotic convergence in exchange for practical convergence (or convergence to a neighborhood); (ii) guarantee non-Zeno behaviors and asymptotic convergence but do not provide a positive minimum inter-event time guarantee; or (iii) are not fully distributed. Additionally, the overwhelming majority of these works provide no form of robustness analysis on the event-triggering strategy. More specifically, if arbitrarily small disturbances can remove the non-Zeno property then the theoretically correct algorithm may not actually be implementable. Instead, this work for the first time presents a fully distributed, robust, dynamic event- triggered algorithm, for general directed communication networks, for which a desired pos- itive minimum inter-event time can be chosen by each agent in a distributed fashion. Sim- ulations illustrate our results.
Calculability of Quark Mixing Parameters from General Nearest Neighbor Interaction Texture Quark Mass Matrices

description: We perform an analysis of general quark mass matrices in the general nearest neighbor interaction form. Excellent agreement with experiment is realized with this general texture, which is neither hermitian nor real-symmetric. We then propose a new class of quark mass matrices that contain no additional parameters other than the quark masses themselves, and thus possess calculability, i.e., ensure a relationship between the six quark masses and four flavor-mixing parameters of the Standard Model.

The evolution of the near-side peak in two-particle number and transverse momentum correlations in Pb-Pb collisions from ALICE

description: Two-particle number and transverse momentum correlations are powerful tools for studying the medium produced in heavy-ion collisions. Correlations in the angular separation of pairs of hadrons can provide information on the medium transport characteristics. In particular, the transverse momentum correlations are sensitive to momentum currents, and provide information about the system life time, the shear viscosity over entropy density ratio ($η/s$) and the system relaxation time ($τ_π$). Furthermore, the interaction of the jets produced in the initial stages of a collision can be studied using number correlations, by observing the medium-induced modification of the near-side jet peak. Measurements of both sets of correlations from Pb-Pb collisions are reported as a function of centrality. Theoretical interpretations and results from Monte Carlo generators are then confronted with the experimental data.

Numerical simulation of flow instability and heat transfer of natural convection in a differentially heated cavity

description: This paper numerically investigates the physical mechanism of flow instability and heat transfer of natural convection in a cavity with thin fin(s). The left and the right walls of the cavity are differentially heated. The cavity is given an initial temperature, and the thin fin(s) is fixed on the hot wall in order to control the heat transfer. The finite volume method and the SIMPLE algorithm are used to simulate the flow. Distributions of the temperature, the pressure, the velocity and the total pressure are obtained. Then, the energy gradient theory is employed to study the physical mechanism of flow instability and the effect of the thin fin(s) on heat transfer. Based on the energy gradient theory, the energy gradient function K represents the characteristic of flow instability. It is observed from the simulation results that the positions where instabilities take place in the temperature contours accord well with those of higher K value, which demonstrates that the energy gradient theory reveals the physical mechanism of flow instability. Furthermore, the effects of the fin length, the fin position, the fin number, and Ra on heat transfer are investigated. It is found that the effect of the fin length on heat transfer is negligible when Ra is relatively high. When there is only one fin, the most efficient heat transfer rate is achieved as the fin is fixed at the middle height of the cavity. The fin blocks heat transfer with a relatively small Ra, but the fin enhances heat transfer with a relatively large Ra. The fin(s) enhances heat transfer gradually with the increase of Ra under the influence of the thin fin(s). Finally, a linear correlation of Kmax with Ra is obtained which reveals the physical mechanism of natural convection from different approaches.

description: Lightweight authenticated ciphers are crucial in many resource-constrained applications,including online payment, edge computing, and the Internet of Things. However, the current standard AES-GCM is not adequate for many applications. Recent developments in Quantum computing increased the urgency of deploying Post-Quantum cryptographic standards that withstand quantum and classic attacks. As a response to these needs, the US National Institute of Standards (NIST) coordinates two standardization processes to evaluate and ratify suitable algorithms. Although resistance to mathematical cryptanalysis is paramount, cost, performance, and resistance to side-channel attacks are among the most critical selection criteria. The development of side-channel protected implementations is necessary for a fair evaluation of candidates since algorithms have a different cost of protection. Real-world implementations, especially lightweight applications with little physical security, are vulnerable to side-channel attacks. As a result, producing side-channel resistant implementations and quantifying the impact of countermeasures on cost and performance shed light on how a given algorithm will perform in practical settings. In this research, we study the effect of applying side-channel countermeasures to the NIST LWC candidates Xoodyak and TinyJAMBU and the NIST PQC candidate Saber with a concentration on hardware implementations. Specifically, we employ the Domain- Oriented masking countermeasure to produce two first-order protected implementations of Xoodyak. For TinyJAMBU, we present a flexible implementation that is synthesizable for arbitrary order of protection. For Saber, we first develop a lightweight design and then apply masking countermeasures. We also report the protection overhead in terms of performance and cost. In parallel, we developed the tools necessary for this research to improve on the existing FOBOS platform. We significantly improved the efficiency and flexibility of the system while using affordable hardware components. Our upgrades resulted in an efficient system capable of performing leakage assessment and attacks on FPGA cryptographic implementations. We also improved the usability of the system to address research and education needs. Our work aims at establishing methodologies and providing tools to develop and evaluate LWC and PQC candidates. Also, the results provide a more realistic look at the practical cost and performance of the algorithms studied.

description: Abelian fermion models described by the SLAC action are considered on a finite 2d lattice. It is shown that modification of these models by introducing additional Pauli - Villars regularization supresses nonlocal effects and provides agreement with the continuum results in vectorial U(1) models. In the case of chiral fermions the phase of the determinant differs from the continuum one.

description: We present a reanalysis of direct CP violation in the decay K_L -> pi^+ pi^- gamma. We point out an existing discrepancy between the theoretical and experimental definitions of epsilon'_{+-gamma}. Adopting the experimental definition of epsilon'_{+-gamma}, we estimate that epsilon'_{+-gamma}/epsilon could be as large as a few times 10^{-4} both within the standard model and beyond. We discuss these estimates in detail and we also show how a judicious choice of E_gamma cuts can increase the sensitivity of the observable epsilon'_{+-γ} to the underlying CP violation.

description: Distance measurements via the dipolar interaction are fundamental to the application of nuclear magnetic resonance (NMR) to molecular structure determination, but they only provide information on the absolute distance $r$ and polar angle $θ$ between spins. In this Letter, we present a protocol to also retrieve the azimuth angle $ϕ$. Our method relies on measuring the nuclear precession phase after application of a control pulse with a calibrated external radio-frequency coil. We experimentally demonstrate three-dimensional positioning of individual carbon-13 nuclear spins in a diamond host crystal relative to the central electronic spin of a single nitrogen-vacancy center. The ability to pinpoint three-dimensional nuclear locations is central for realizing a nanoscale NMR technique that can image the structure of single molecules with atomic resolution.

description: We study chiral symmetry breaking in the Nambu--Jona-Lasinio model regularized in proper-time in arbitrary space-time dimensions through an iterative procedure by writing the gap equation in the form of a discrete dynamical system with the coupling constant as the control parameter. Expectedly, we obtain the critical coupling for chiral symmetry breaking when a nontrivial solution bifurcates away from the trivial one and becomes an attractor. By increasing further the value of the coupling constant, we observe a second bifurcation where the dynamical solution is no longer an attractor, and observation that holds true in all space-time dimensions. In the super-strong coupling regime, the system becomes chaotic.

Unity of Forces at the Preon Level with new Gauge Symmetries

description: In the context of a viable, supersymmetric,preon model,it has been shown by Babu and Pati that the unity of forces can well occur at the level of preons near the Planck scale.This preonic approach to unification is explored further in this note with the inclusion of threshold effects which arise due to spreading of masses near the scale of suppersymmetry ($M_S=1$ TeV) and the metacolor scale ($Λ_M=10^11$ GeV).These effects,which were ignored in the earlier work,are found to have marked consequences on the running and unification of relevant couplings leading to new possibilities for flavor-color as well as metacolor gauge symmetries.In particular, allowing for seemingly reasonable threshold effects,it is found that the metacolor gauge symmetry,$G_M$ is either $SU(6)_M$ or $SU(4)_M$ (rather than $SU(5)_M$) and the corresponding flavor-color gauge symmetry is either $SU(2)_LXU(1)_RXSU(4)_C$ (for $G_M=SU(6)_M$) or even just the standard model symmetry $SU(2)_LXU(1)_YXSU(3)_C$ (for $G_M=SU(6)_M or SU(4)_M$). Prospects of other preonic gauge symmetries are also investigated.

From MVPs to pivots: a hypothesis-driven journey of two software startups

description: Software startups have emerged as an interesting multiperspective research area. Inspired by Lean Startup, a startup journey can be viewed as a series of experiments that validate a set of business hypotheses an entrepreneurial team make explicitly or inexplicitly about their startup. It is little known about how startups evolve through business hypothesis testing. This study proposes a novel approach to look at the startup evolution as a Minimum Viable Product(MVP) creat- ing process. We identified relationships among business hypotheses and MVPs via ethnography and post-mortem analysis in two software star- tups. We observe that the relationship between hypotheses and MVPs is incomplete and non-linear in these two startups. We also find that entrepreneurs do learn from testing their hypotheses. However, there are hypotheses not tested by MVPs and vice versa, MVPs not related to any business hypothesis. The approach we proposed visualizes the flow of entrepreneurial knowledge across pivots via MVPs.
title: Towards a Biological Understanding of Parenting Across Contexts

description: Parenting is not only essential for species survival but also has long been apredictor of child success across a number of social, cognitive, and psychological domains. Parenting—like all behaviors—is in part biologically driven. Knowledge of such biological underpinnings sheds light into how parenting operates—providing important new directions for interventions and basic science alike. With the advent of neuroimaging, questions of biological bases for parenting have been answered with greater specificity than ever before. To date dozens of studies have been published on the neural correlates of parent responses to children, though a comprehensive quantitative review of this literature is lacking. Thus, Study 1 of this dissertation was a meta-analysis, using activation likelihood estimation, of all existing neuroimaging studies (N=59) of parent responses to children to identify possible neural networks involved in caregiving. Further, this study examined variations in the neural networks as a function of parent gender, child age, child negative as compared to other emotion, and own child stimuli as compared to another child’s stimuli. Results revealed coordination of emotional arousal, reward, social cognitive, and sensorimotor brain networks across studies. However, one of the most important gaps identified in this study was the absence of neuroimaging studies with parents from diverse backgrounds or contexts with heightened environmental stressors (e.g. poverty, discrimination). Therefore, building on this foundation, Study 2 of this dissertation was a fMRI pilot study of 16 first generation Latinx mothers of a 10-14 year old adolescent. This study examined the neural correlates of parenting in a group that has not been studied previously and a group that is disproportionately affected by threat of deportation/immigration stress, poverty, and limited access to mental health care but a group that also has a variety of unique cultural strengths. Mothers were scanned using fMRI while looking at videos of their own child in a parent-child discussion as compared to another age, gender, and ethnically matched child. Results from this study revealed engagement of similar networks to the overall meta-analysis (social cognition, sensorimotor) with a particular emphasis on empathy related networks as underpinning parent responses to their child in Latinx mothers and parent responses when their child had heightened psychological symptoms (externalizing symptoms). Networks involved in fear and pain responses were found to underpin harsh/inconsistent parenting. Networks involved in motor coordination, which may represent a certain physical hypervigilance or “on edge feeling”, were related to both heightened immigration stress and heightened harsh/inconsistent parenting, suggesting the brain as a possible pathway from unique stressors to parenting behaviors. Implications of such findings and directions for future research are discussed.
