Acta Crystallographica Section D, EarlyView.A Bayesian perspective on orientation estimation in cryo‐EM is presented, with the minimum mean‐square error estimator outperforming standard cross‐correlation‐based approaches, particularly under challenging low signal‐to‐noise conditions. We demonstrate that improved orientation estimation has a decisive impact on 3D reconstruction quality and ...

International Journal of Urban and Regional Research, EarlyView.Abstract Africa is recognized as the final frontier for urbanization and capitalism. Following a long wave of massive loans to promote state‐led developments, small private foreign and local developers are transforming the urban landscape on the outskirts of Luanda, forging partnerships with Angola's national and local governments and developing an ...

Insect Science, EarlyView.The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Accounting Perspectives, EarlyView.ABSTRACT Artificial intelligence (AI) tools are used to assist auditors in analyzing large amounts of data, automating audit tasks, and identifying risks and opportunities. AI can help improve the efficiency and accuracy of the auditing process as well as create value for both audit firms and their clients.

Late Antique Allāh: Ancestral Arabian Religion and the Monotheistic Zeitgeist
Arabian Archaeology and Epigraphy, EarlyView.ABSTRACT This essay addresses the ongoing scholarly tension between the monotheistic interpretations of late pre‐Islamic Arabian religion, pioneered by G. Hawting and P. Crone, and the traditional accounts of rampant Arabian polytheism found in later Islamic literary sources.

Defence Contracting and Accrual‐Based Earnings Management
Accounting &Finance, EarlyView.ABSTRACT We examine accrual‐based earnings management in Spanish defence firms in 2011–2020, using a unique database from the Spanish Ministry of Defence. We find higher levels of accrual‐based earnings management and lower accrual quality in firms where defence contracts represent a high proportion of their total sales.

Solutions to semilinear elliptic PDE's with biharmonic operator and singular potential
Electronic Journal of Differential Equations, 2016 We study the existence and nonexistence of positive solution to the problem $$\displaylines{ \Delta^2u-\mu a(x)u=f(u)+\lambda b(x)\quad\text{in }\Omega,\cr u>0 \quad\text{in }\Omega,\cr u=0=\Delta u \quad\text{on }\partial\Omega, }$$ where $\Omega$

Food without fire: Environmental and nutritional impacts from a solar stove field experiment
American Journal of Agricultural Economics, EarlyView.Abstract Over 80% of the population in rural Sub‐Saharan Africa relies on biomass cooking fuel, a substantial source of anthropogenic greenhouse gases. We use a field experiment in Zambia to investigate the impact of solar stoves on biomass fuel use and cooking habits.

Nonexistence of solutions to systems of higher-order semilinear inequalities in cone-like domains
Electronic Journal of Differential Equations, 2002 In this paper, we obtain nonexistence results for global solutions to the system of higher-order semilinear partial differential inequalities $$displaylines{ frac{partial^k u_i}{partial t^k}-Delta (a_i (x,t) u_i (x,t)) geq t^{gamma_{i+1}}|x|^{sigma_{i+1}}
