Projective well-orderings and bounded forcing axioms

Journal of Symbolic Logic, 2005
AbstractIn the absence of Woodin cardinals, fine structural inner models for mild large cardinal hypotheses admit forcing extensions where bounded forcing axioms hold and yet the reals are projectively well-ordered.

A Universe with large Continuum, global $Σ$-Uniformization and a projective Well-Order of its Reals [PDF]

We construct a model in which the continuum has size $κ$ for a regular cardinal $κ$ and in which the $Σ^1_n$-uniformization property holds simultaneously for every $n \ge 2$. Additionally this model has a $Δ^1_3$- definable well-order of its reals.

Metrics admitting projective and c-projective vector fields [PDF]

, 2023
Vector fields on a smooth manifold with an affine connection are called projective (resp. c-projective) if their local flows preserve geodesics (resp. J-planar curves). In this expository paper, metrics with such vector fields are discussed.

Jensen ${\Delta }_n^1$ Reals by Means of ZFC and Second-Order Peano Arithmetic

Axioms
It was established by Jensen in 1970 that there is a generic extension L[a] of the constructible universe L by a non-constructible real a∉L, minimal over L, such that a is Δ31 in L[a].

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

FEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Almost Projective Semimodules

, 2023
الهدف من هذا البحث هو دراسة مفهوم شبه المقاس الاسقاطي تقريبا كأعمام الى شبه المقاس الاسقاطي.  بعض الخصائص الاساسية لهذا المفهوم تم مناقشتها, كذلك  بعض النتائج  تم اعمامها الى صنف شبه المقاسات الاسقاطية تقريبا.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
