Existence results for a multipoint boundary value problem of nonlinear sequential Hadamard fractional differential equations

open access: yesCubo, 2021
In this paper, existence and uniqueness results are established for a nonlinear sequential Hadamard fractional differential equation with multi-point boundary conditions, via Banach and Krasnosel'skiǐ's fixed point theorems and Leray-Schauder nonlinear ...

Existence and structure of P-area minimizing surfaces in the Heisenberg group [PDF]

open access: yesarXiv, 2021
We study existence and structure of $P-$area minimizing surfaces in the Heisenberg group under Dirichlet and Neumann boundary conditions. We show that there exists an underlying vector field $N$ that characterized existence and structure of $P$-area minimizing surfaces. This vector field exists even if there is no $P$-area minimizing surface satisfying

Using local ecological knowledge to determine the status of Cantor's giant softshell turtle Pelochelys cantorii in Kerala, India

open access: yesOryx
The Critically Endangered Cantor's giant softshell turtle Pelochelys cantorii is a freshwater turtle found in South and Southeast Asia. Its population is declining because of habitat destruction and alteration, and hunting for its meat.

Quantum-Inspired Perfect Matching under Vertex-Color Constraints [PDF]

open access: yesarXiv, 2022
We propose and study the graph-theoretical problem EXISTS-PMVC: the existence of perfect matching under vertex-color constraints on graphs with bi-colored edges. EXISTS-PMVC is of special interest because of its motivation from quantum-state identification and quantum-experiment design, as well as its rich expressiveness, i.e., EXISTS-PMVC naturally ...

Quantum Advantage from One-Way Functions [PDF]

open access: yesCrypto 2024, 2023
We demonstrate quantum advantage with several basic assumptions, specifically based on only the existence of OWFs. We introduce inefficient-verifier proofs of quantumness (IV-PoQ), and construct it from classical bit commitments. IV-PoQ is an interactive protocol between a verifier and a quantum prover consisting of two phases.

FoxO1 signaling in B cell malignancies and its therapeutic targeting

open access: yesFEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.

The existential role of women in The Flies and the dirty hands, by Jean Paul Sartre

open access: yesمجلة الآداب, 2021
The freedom and the existential engagement represent two essential notions in the mind of the writer Jean-Paul Sartre. It has been presented in a good and clear way by his philosophy or, in a clearer way, by his artworks. More specifically, the two plays

The immunological interface: dendritic cells as key regulators in metabolic dysfunction‐associated steatotic liver disease

open access: yesFEBS Letters, EarlyView.
Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Insights into PI3K/AKT signaling in B cell development and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
This Review explores how the phosphoinositide 3‐kinase and protein kinase B pathway shapes B cell development and drives chronic lymphocytic leukemia, a common blood cancer. It examines how signaling levels affect disease progression, addresses treatment challenges, and introduces novel experimental strategies to improve therapies and patient outcomes.

Diphthamide synthesis is linked to the eEF2‐client chaperone machinery

open access: yesFEBS Letters, EarlyView.
The diphthamide modification of eukaryotic translation elongation factor 2 (eEF2) is important for accurate protein synthesis. We addressed the potential coordination of de novo eEF2 synthesis with simultaneous or subsequent diphthamide modification. Our work reveals that the co‐chaperones Hgh1 and Cpr7, which are known to support folding of nascent ...
