End-to-end pseudo-measurement learning for state estimation under limited observability

J.G. De la Varga · S. Pineda · A. Stratigakos · J.M. Morales

Distribution System State Estimation (DSSE) is becoming increasingly important with the integration of Distributed Energy Resources (DERs) and the active operation of distribution networks (DNs), but it remains challenging due to the limited and heterogeneous monitoring infrastructure available in these networks. To ad...

Relations between higher level Hurwitz class numbers

Ngoc Trinh Le

We connect generalizations of the classical Hurwitz class numbers coming from two different frameworks: one introduced by Pei and Wang, arising from the generalized Cohen--Eisenstein series, and another by Li, Skoruppa, and Zhou, arising from Eichler orders of quaternion algebras. As applications, we obtain new basis f...

Characterization of two key cytochrome P450 enzymes in Isodon amethystoides and de novo production of 3α,15β-dihydroxy-ent-kaurene in yeast

Yanying, Chen · Xinqi, Song · Yanan, Wang · Yang, Han · y 8 más

Glaucocalyxin A (GLA), a well-known ent-kaurene diterpenoid, has emerged as a high-value bioactive natural product in pharmaceutical research owing to its potent and broad-spectrum activities. To date, its total synthesis has proven extremely challenging due to poor yield and intricate routes, and the biosynthetic path...

Genome-integrated engineering of Escherichia coli Nissle 1917 enables sustained gut-local biosynthesis of 5-hydroxytryptophan

Jing Wu · Yifan Yang · Taiyu Li · Baohui Zhang · y 3 más

5-Hydroxytryptophan (5-HTP) is a functional precursor of serotonin; however, achieving sustained 5-HTP production in vivo by engineered microbes remains challenging. To address this, we developed a genome-integrated engineered probiotic system enabling gut-local biosynthesis of 5-HTP. Escherichia coli Nissle 1917 (EcN)...

The role of dormancy in survival under periodic stress: A delayed chemostat model

Taieb, Ruben · Adimy, Mostafa · Amster, Pablo

In this paper, we investigate the impact of dormancy on the survival of a population in a periodic environment. We extend the classical periodic chemostat model by including a quiescent compartment with nutrient-dependent dormancy and activation rates, together with a maturation delay between nutrient consumption and r...

Strategy for enhanced production of A40926B0 in Nonomuraea gerenzanensis using an efficient CRISPR/AsCas12f1 system

Xiaoru Wang · Hongmei Zhai · Dandan Gu · Yongchao Wang · y 5 más

The global emergence of vancomycin-resistant Gram-positive pathogens underscores the urgent need for efficient production of novel lipoglycopeptide antibiotics. Dalbavancin, a last-resort therapeutic agent, relies on its key biosynthetic precursor A40926B0, whose industrial manufacture is severely limited by the low yi...

Comparison between formal slopes and p-adic slopes

Yezheng Gao

In this paper, we establish several inequalities comparing formal slopes with p-adic slopes of solvable differential modules over the punctured open unit disc. Our approach is based on a delicate analysis of Newton polygons and the log-convexity of generic radius functions.

Pseudorepresentations not arising from genuine representations

Luo, Jinyue

We show that a pseudorepresentation $\D\colon A[G] \rightarrow A$ of a (finite) group $G$ need not arise from a genuine representation, even if one is allowed to extend the ring~$A$. This shows that a theorem of the ``embedding problem'' for residually multiplicity free pseudorepresentations ~\cite[Proposition~1.3.13]{...

Benford behavior resulting from stick and box fragmentation processes

Fang, Bruce · Miller, Steven J.

Benford's law is the statement that in many real world data sets, the probability of having digit $d$ in base $B$ as the first digit is \log_{B}\!\left(\frac{d+1}{d}\right) for all $1 \leq d \leq B$. We sometimes refer to this as weak Benford behavior, and we say that a data set satisfies strong Benford behavior in bas...
