Governing Singularities of Schubert Varieties

open access: yes, 2006
We present a combinatorial and computational commutative algebra methodology for studying singularities of Schubert varieties of flag manifolds. We define the combinatorial notion of *interval pattern avoidance*.

Unlocking the Nexus of Carbon Reduction in China’s Road Transportation: A Two‐Stage Decomposition Analysis

open access: yesJournal of Advanced Transportation, Volume 2026, Issue 1, 2026.
China faces urgent road transportation carbon emission (RTC) reduction under its “dual carbon” goals. Achieving RTC reduction necessitates not only identifying key driving factors but also clarifying the sectoral linkages closely associated with RTC.

Axion model with intermediate scale fermionic dark matter

open access: yesPhysics Letters B, 2020
We investigate a non-supersymmetric SO(10)×U(1)PQ axion model in which the spontaneous breaking of U(1)PQ occurs after inflation, and the axion domain wall problem is resolved by employing the Lazarides-Shafi mechanism.

Quantitative Assessment of Human Factors in Civil Aircraft Flight Test Risks Based on Fuzzy Bayesian Network and Improved HFACS Model

open access: yesInternational Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.
Human factors play an important role in civil aviation safety, which is also vital in flight tests. To significantly reduce the possibility of accidents induced by human errors during the flight test, systematic assessment of human factor risks, determination of the critical causes of accidents, and designs of targeted preventive strategies are ...

“Thou Shalt not Smoke”: Religion and smoking in a natural experiment of history

open access: yesSSM: Population Health, 2019
We provide a new identification strategy to analyse the implications of religious affiliation on unhealthful behaviour by focusing on the link between religiousness and smoking.

Does the interest tax shield align with maqasid al Shariah in finance?

open access: yesBorsa Istanbul Review, 2019
The debt-equity distinction is critical in modern corporate finance. We assess the compliance of the interest tax shield with the maqasid al Shariah in finance. For our analysis, we use the ends of maqasid al Shariah as proposed by Akram Laldin & Furqani,

A model of dynamical SUSY breaking

open access: yesPhysics Letters B, 2019
Supersymmetric (SUSY) models and dynamical breaking of symmetries have been used to explain hierarchies of mass scales. We find that a chiral representation, 10‾⊕5‾⊕2⋅5 in SUSY SU(5) in the hidden sector, breaks global SUSY dynamically, by producing a ...

A novel molluscicide: investigating the efficacy of the Penicillium aurantiocandidum Z12 strain in controlling the schistosome-transmitting snail Oncomelania hupensis

open access: yesMolluscan Research
Oncomelania hupensis, the sole intermediate host for Schistosoma japonicum, is a barrier to schistosomiasis elimination. Currently, chemical molluscicides are widely used; however, they can lead to environmental residues and toxicity problems.
