On linear global instability at the leading edge of a short compression corner with large ramp angle

Abstract Global linear stability analysis of Mach 3 flow over a short compression corner is investigated at Reynolds number 11200 and Knudsen number O(10−4), for the first time using both kinetic theory direct simulation Monte Carlo (DSMC) and continuum Navier–Stokes–Fourier (dir...

Simulating the jittering-jets explosion mechanism: circum-jet rings account for observed core-collapse supernova remnant morphologies

We conduct three-dimensional hydrodynamical simulations of core-collapse supernova (CCSN) explosion driven by jets in the framework of the jittering jets explosion mechanism (JJEM), and obtain a pair of opposite circum-jet rings similar to those observed in some CCSN remnants (CC...

Spatially Controlled Release from Printable Microgels for Embedded Bioprinting

Abstract Granular hydrogels composed of jammed microgels have emerged as promising biomaterials for 3D bioprinting due to their tunable viscoelastic properties and ability to incorporate bioactive molecules and encapsulate cells within the interstitial spaces between the particle...

The jet-shaped pipe morphology in planetary nebulae and core-collapse supernova remnants

We compare images of core-collapse supernova (CCSN) remnants (CCSNRs) and jet-shaped planetary nebulae (PNe) that have a narrow, faint zone extending from side to side, termed a pipe, with a hydrodynamical numerical simulation exploding a massive star with three pairs of jets in...

Performance and issues of consolidation polymers for applications in conservation of outdoor cultural heritage: A review

Outdoor stone cultural heritage is constantly subject to coupled temperature and moisture cycling, salt transport and crystallization, solar radiation, atmospheric chemistry, and biological activity. Under such conditions, the field performance of polymer-based consolidants and p...

Comprehensive Approach to Directly Addressing Estimation Delays in Stochastic Guidance

In realistic pursuit–evasion scenarios, abrupt target maneuvers generate unavoidable periods of elevated uncertainty that result in estimation delays. Such delays can degrade interception performance to the point of causing a miss. Existing delayed-information guidance laws fail...

Shock propagation through a local constriction

The interaction of a moving shock wave with a localised constriction in a straight conduit is studied using large-eddy simulations, validated against time-resolved schlieren imaging and wall-pressure measurements from shock-tube experiments. The blockage ratio (0.35–0.75) and the...

Characterizing the Novel CRP, IP-10, and TRAIL Host-Response Protein Signature in Pediatric Kingella kingae Infections—A Retrospective Cohort Study

Background: Kingella kingae is a primary cause of pediatric osteoarticular infections. Diagnosis is challenging due to mild clinical presentations and fastidious culture growth, often mimicking viral illnesses. The MeMed BV™ assay measures C-reactive protein (CRP), interferon gam...

The mitochondrial chaperone HSPD1 folds MTHFD2 independently of its co-chaperone HSPE1

Acquiring new cellular states entails metabolic reprogramming driven by changes in the expression of cytosolic and mitochondrial metabolic enzymes. Most mitochondrial proteins are synthesized in the cytosol and imported into the mitochondria in a linear form, after which they are...

Twisted Representations of Product Systems of $$C^*$$-Correspondences: Wold Decomposition and Unitary Extensions

Abstract We investigate Wold-type decompositions and unitary extension problems for multivariable isometric covariant representations associated with product systems of $$C^*$$ C ∗ -correspondences. First, we establish an operator-theoretic characterization for the existence of a...

Non-equilibrium stabilization of sulfur-rich zinc blende Cu1+δI1−xSx alloys with ultra-degenerate p-type conductivity

High-performance p-type transparent conductors are limited by low conductivity and poor stability. Here, we report the synthesis of Cu1+δI1−xSx alloy films via non-equilibrium magnetron co-sputtering, enabling sulfur incorporation beyond the thermodynamic solubility limits. X-ray...

Soil response at low stress in laminar box tilt table testing

The capability of direct in-soil measurement of shear stress and shear strain has been applied to 1 g tilt table laminar box tests. The aim of the study is to evaluate the stiffness response of the material tested under low to ultra-low vertical stresses. The tests were performed...

Dependent reachable sets for the constant bearing pursuit strategy

This paper introduces a novel reachability problem for the scenario involving two agents, where one agent follows another agent using a feedback strategy. The geometry of the reachable set for an agent, termed dependent reachable set, is characterised using the constant bearing p...

Dermatological Diseases and Household Behavioral Spillovers: A Conceptual Framework

Background: Chronic diseases may generate behavioral responses extending beyond the affected individual. Although family health effects and behavioral spillovers have been examined in health economics and behavioral research, their relevance to dermatological disease management h...

Pre-combustion fuel reforming in gas turbines: Hydrocarbon and carbon-neutral fuel pathways

Gas turbines are a cornerstone of modern power generation, providing reliable and dispatchable electricity across the globe. However, their significant contribution to global CO 2 emissions has become increasingly untenable under international climate agreements such as the Paris...

The lipidomic architecture of the mouse brain

Abstract Lipids are fundamental components of the brain, crucial for synaptic transmission and signal propagation. Altered brain lipid composition is associated with common and rare neuropathologies, yet the spatial organization of the mammalian brain lipidome remains insufficien...

The gene-regulatory evolution of the human skeleton

Abstract Skeletal modifications were central to human evolution, enabling adaptations for bipedalism, large cranial vaults and childbirth 1 . Despite their importance, the genetic changes that gave rise to the unique human form remain mostly unknown 2 . Here we systematically map...

On the Cost of Conforming to Reviewers’ Expectations and the Potential Benefit of Prediction Competitions

Although academic peer review offers many important benefits, it can also impede scientific exploration. For instance, when reviewers share restrictive working assumptions, researchers may be incentivized to conform to them, even when alternative conjectures could better advance...

From everyday chemistry to formal modeling: a progressive approach to integrating systems thinking in chemistry

Abstract Systems thinking in chemistry involves reasoning that integrates the macroscopic, microscopic, symbolic, and process-level representations of bounded systems. This article proposes a practice-oriented progression from a deliberately simplified everyday chemistry task to...

Modeling Incomplete Solute Mixing at Pipe Junctions in Water Distribution Networks: Parametric CFD Simulations and a Predictive Regression Approach

Abstract High-quality drinking water is essential for modern settlements, and accurate modeling of solute mixing at pipe junctions is crucial in water distribution networks (WDNs). While complete mixing is often assumed, recent studies emphasize the need to account for incomplete...
