CPL‐Diff: A Diffusion Model for De Novo Design of Functional Peptide Sequences with Fixed Length

Advanced Science, EarlyView.
This study presents a diffusion model for generating functional peptide sequence lengths using mask control. The model can generate antimicrobial, antifungal, and antiviral peptides with specific lengths on demand. The model learns the structure of peptides better and generates peptides with better physicochemical properties, and the model has good ...

Hydrogeological feasibility of mine water deep geological storage in Baotashan coarse sandstone: A case study in Ordos Basin

Deep Underground Science and Engineering, Volume 1, Issue 2, Page 148-164, December 2022., 2022
We conducted a new approach of mine water‐deep geological storage, the results showed that the hydrogeological feasibility of Baotashan coarse sandstone (BCS) was impressive and useful for real project. The effective porosity of BCS aquifers ranged from 1.36% to 3.46% and the capacity of mine water geological storage was 0.455–1.266 Mm3 for 1 km2 in ...

Chromosome‐Level Genome Assembly of the Leafcutter Bee Megachile rotundata Reveals Its Ecological Adaptation and Pollination Biology

Advanced Science, EarlyView.
The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

Markov Chain Approximations to Singular Stable-like Processes [PDF]

arXiv, 2012
We consider the Markov chain approximations for singular stable-like processes. First we obtain properties of some Markov chains. Then we construct the approximating Markov chains and give a necessary condition for weak convergence of these chains to singular stable-like processes.

Predation thresholds for reintroduction of native avifauna following suppression of invasive Brown Treesnakes on Guam

Ecological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract The brown treesnake (BTS) (Boiga irregularis) invasion on Guåhan (in English, Guam) led to the extirpation of nearly all native forest birds. In recent years, methods have been developed to reduce BTS abundance on a landscape scale. To help assess the prospects for the successful reintroduction of native birds to Guåhan following BTS ...

Graphs: Associated Markov Chains [PDF]

arXiv, 2012
In this research paper, weighted / unweighted, directed / undirected graphs are associated with interesting Discrete Time Markov Chains (DTMCs) as well as Continuous Time Markov Chains (CTMCs). The equilibrium / transient behaviour of such Markov chains is studied.

Deterministic chaos for Markov chains [PDF]

arXiv, 2020
We find that Markov chains with finite state space are Poincare chaotic. Moreover, finite realizations of the chains are arcs of each unpredictable orbit for sure. An illustrating example with a proper numerical simulation is provided.

Regularity of harmonic functions for some Markov chains with unbounded range [PDF]

arXiv, 2012
We consider a class of continuous time Markov chains on $\Z^d$. These chains are the discrete space analogue of Markov processes with jumps. Under some conditions, we show that harmonic functions associated with these Markov chains are H\"{o}lder continuous.
