A layered dynamic material flow framework for modeling building renovations

Abstract Dynamic material flow analysis (dMFA) is widely used to study the material demands of residential building stocks. In most of the studies conducted to date, buildings are modeled as homogeneous units instead of a system of components. A limitation of this assumption is t...

Wehrl Inequalities for Matrix Coefficients of Holomorphic Discrete Series

Facilitating megacity electricity decarbonization via grid-interactive demand-side resource management

City power systems face intensified mismatches between generation and dynamic demand under rising zero-carbon energy penetration levels. Although demand-side resource management offers mismatch mitigation potential by regulating load patterns, its city-level capability remains un...

Influence of speech characteristics on working memory and perceived workload: Findings from experimental listening experiments

Exposure to background speech is known to impair working memory performance, a concern particularly relevant in open-plan office environments. This study aimed to examine how specific characteristics of speech, including semantic content and sound pressure level, affect cognitive...

Fast, unconditional reset and leakage reduction in fixed-frequency transmon qubits

Abstract On-demand qubit-state initialization is a prerequisite for quantum computation. We demonstrate such a protocol in a device consisting of fixed-frequency transmon qubits pair-wise coupled via tunable couplers — an architecture that is also compatible with the surface code...

Influence of piston cooling jet and renewable fuel blends on particulate emissions in a gasoline engine

Replacing a portion of the hydrocarbons in fossil fuels with renewable ones can lower net carbon dioxide (CO 2 ) emissions but may increase engine-out pollutants. Gasoline direct injection (GDI) engines emit particle number (PN) emissions due to fuel evaporation, mixing, and fuel...

The Total and Polarized Radio Emission from the Innermost Jets of a High-Redshift Quasar and a Candidate at Parsec-Scale Resolution

High-frequency very long baseline interferometry (VLBI) polarimetry probes synchrotron-emitting plasma closer to the central engines of radio-loud active galactic nuclei (AGNs), but observations above 43 GHz are technically demanding. We present 22-GHz European VLBI Network obser...

Silica-EmbeddedProteins Enable Higher Yield and AtomicIon Detection in Deep-UV Laser-Assisted Atom Probe Tomography

Abstract Determining the 3D structure of proteins is a long-standing challenge in the life sciences and is of paramount importance for understanding fundamental biological processes and advancing pharmaceutical development. Experimental techniques such as X-ray diffraction, nucle...

Architecture and gathering: on spatiality, conception and revaluation in material reuse practice

Purpose This paper seeks to advance the gathering of used materials for construction both as a practice and as a conceptual framework relevant to architecture. It critically examines disposed building materials, including their societal flows, their role in design processes and t...

Containerized Truck Movements in Sweden Payload and Empty Trip Modeling

ABSTRACT Container flows account for 12% of truck traffic in Sweden. Unlike other freight, container truck movements mostly involve import or export cargo that begins or ends at ports. However, containerized cargo has different payloads and empty trip patterns. Hence, this paper...

Modernizing the TRIAD ecological risk assessment framework. Part II: Omic methods for high-resolution biological risk indicators

<ns5:p>The TRIAD framework is a widely used approach to assess site-specific ecological risk by integrating three Lines of Evidence (LoE): chemical, ecotoxicological, and ecological. As environmental contamination grows increasingly complex, the framework requires modernization i...

Layered Defect-Filling co-Assembled Carbazole-Based SAMs Deliver 20% Organic Solar Cells and 17% Mini-Modules

Abstract Self-assembled monolayers (SAMs) are widely used as hole-transport layers (HTLs) in organic solar cells (OSCs), yet conventional single-component SAMs often form quasi-monolayers with incomplete coverage and interfacial defects that become increasingly detrimental upon d...

Optimization based on timed Petri nets using CP-SAT - an integrated SAT and CP solver

Abstract A simple but general semantics for timed Petri nets is presented in this paper. Based on this semantics, an optimization formulation is introduced and implemented in a recently developed optimization solver, where a satisfiability (SAT) solver is integrated with constrai...
