We present a general technique for efficient computation of second order information for optimization functionals involving many variables of different nature, frequently appearing in modern applications. This technique relies on the bilinear Hessian, and while the main tools for this task have been published elsewhere, we here focus on the problem of how to organize the computations in the multi-
Background: Stroke remains a global health challenge, with its burden disproportionately affecting developing nations, including Iran. Rapid access to medical care is crucial for improving outcomes. However, spatial and temporal factors often leads to delays, adversely impacting survival. This study investigated predictors of in-hospital mortality among stroke patients in Mashhad, Iran, with a nov
Spiral galaxies, like the Milky Way, transform at some point in time into a rotationally supported system. Using an extant dataset consisting of 319,835 subgiants from LAMOST with precise ages from the literature, we determine, for the first time, the age when the Milky Way disk spins up, i.e., when the mean circular velocity changes from halo-like to disk-like. We find in concordance previous stu
Regional carbon dioxide (CO₂) and methane (CH₄) source contributions were analysed at two European coastal observatories, El Arenosillo (ARN) in southwestern Spain and Capo Granitola (CGR) in southern Italy, using in situ observations and STILT model simulations from 2006 to 2023, enabling source attribution to biogenic, fossil fuel, anthropogenic, and natural contributions. Model-observation agre
Inclination-dependent grain boundary (GB) energy and shear-coupled motion are studied for [001] and [111] tilt GBs in face-centered cubic materials using three-dimensional (3D) phase field crystal (PFC) simulations. A large dataset spanning misorientation and inclination space is systematically generated to evaluate trends in GB energy and shear-coupling. GB energy variations broadly follow ideal
Beamstopper-Integrated Sensors (BIS) based on silicon carbide (SiC) represent a novel class of compact, radiation hard devices that combine beam interception with real-time diagnostics. We present the first characterization of four-quadrant BIS designed for simultaneous intensity and position monitoring on synchrotron beamlines. Based on the established reliability of single-pixel BIS as intensity
Recovery of plastically deformed metals involves several stages of substructure evolution during which dislocation entanglements and networks become increasingly organized, thereby lowering the stored energy in the material. Central to recovery is the formation and evolution of subgrains, which is also recognized as a recrystallization precursor. In this paper, subgrain coarsening is investigated

This article deals with the possible existence of deliberate fertility control before the fertility transition. The timing of the fertility response to economic stress, as measured by fluctuations in grain prices, is used as a measure of deliberate, but non-parity specific, control. Birth histories from six German villages (1766–1863), including information on occupation of the husband, are used t
Epidemiological perspectives applied to the study of socioeconomic inequalities in health are characterized by a one-dimensional approach to social differences, as income, occupation, and education are used as interchangeable variables to capture social inequalities. This paper calls into question this assumption by exploring the impact of parent's education and occupation on their newborns' healt

Background: Participants in epidemiological cohorts may not be representative of the full invited population, limiting the generalizability of prevalence and incidence estimates. We propose that this problem can be remedied by exploiting data on baseline participants who refused to participate in a re-examination, as such participants may be more similar to baseline non-participants than what base
Antiferromagnetic (AF) materials offer a route to realising high-speed, high-density data storage devices that are robust against magnetic fields due to their intrinsic dynamics in the THz-regime and the lack magnetic stray fields. The key to functionality and efficiency is the control of AF domains and domain walls. Although AF domain structures are known to be sensitive to magnetoelastic effects
