Amid ambitious net-zero goals and growing demands for freight logistics, addressing the climate challenges posed by the heavy-duty truck (HDT) sector is an urgent and pivotal task. This study develops an integrated HDT model by incorporating vehicle dynamic simulation and life cycle analysis to quantify energy consumption, greenhouse gas (GHG) emissions, and total cost of ownership associated with three emerging powertrain technologies in various truck use scenarios in China, including battery electric, fuel cell electric, and hydrogen combustion engine trucks. The results reveal varying levels of economic suitability for these powertrain alternatives depending on required driving ranges and duty cycles: the battery electric for regional-haul applications, the hydrogen fuel cell for longer-haul and low-load driving conditions, and the hydrogen combustion engine to meet high power requirements.

January 2025
From the Department of Plastic Surgery and Hand Surgery, Cantonal Hospital Aarau, Aarau, Switzerland.
Background: Abdominal wall reconstruction represents an ambitious and demanding challenge. This study aimed to illustrate the versatility of the anterolateral thigh (ALT) flap in its different designs for the reconstruction of complex defects of the abdominal wall.
Methods: Charts of patients with complex abdominal wall defects who underwent a reconstruction with an ALT flap at the University Hospital of Zurich (2018-2020) were reviewed retrospectively.
Assessing Cigarette Reduction Tax-Effectiveness in Low Tobacco Expenditure Contexts: An Application to Bolivia.
Health Econ

Centro de Investigaciones Económicas y Empresariales, Universidad Privada Boliviana, La Paz, Bolivia.
In this research we show that ambitious increases in tobacco tax rates can substantially reduce tobacco consumption, increase fiscal revenue, and provide net positive social benefits even in contexts of low consumption prevalence and intensity. Low nicotine intake still constitutes a grave disease risk factor, and the effectiveness of tax increases might be questioned if income effects are small. We adapt spatial variation of price methodologies to deal with low prevalence and intensity, censored data, and small samples using the Bolivian case as an illustration.

Center for Global Sustainability, University of Maryland, College Park, MD, USA.
In 2025, countries are expected to submit a third round of nationally determined contributions (NDCs) that outline emission reduction goals for 2035. These new NDCs will be important for global alignment with the Paris Agreement's long-term goals. Setting an ambitious and plausible 2035 NDC in the United States (US) could be crucial in motivating high levels of ambition globally.

The multiple crises (climate, biodiversity, austerity) facing our socio-ecological systems require ambitious responses; with much of the responsibility for protecting public goods and developing sustainably lying with public policy. To tackle these wicked problems, there are increasing calls for policy coherence: to use the levers of government in a more holistic and systemic manner. Land use transformation is crucial to achieving these ambitions.
