Journal of Combinatorial Theory, Series A, 1996 \textit{J. A. Thas} [Eur. J. Comb. 8, 441-452 (1987; Zbl 0646.51019)] completely characterizes the flocks of a quadratic cone whose planes share a common point. The authors establish a fundamental relationship between \(s\)-locally rigid groups and intersections of the planes of the partial flock.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Journal of Combinatorial Theory, Series A, 1999 \textit{T. Penttila} and \textit{B. Williams} [Geom. Dedicata, to appear] have constructed a sporadic translation ovoid of the quadrangle \(Q(4, 3^5)\). Associated with this, there is a new (semifield) flock of a quadratic cone in \(\text{PG}(3,3^5)\), and hence a flock generalized quadrangle of order \((3^5,3^{10})\).

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.

Discrete Mathematics, 2002 This interesting article deals with flocks of the quadratic cone \(K\) of \(PG(3, q)\) with equation \(x_0x_1 = x_2^2\) and vertex \(v = (0,0,0,1)\). A flock \(F\) of \(K\) is a partition of \(K \setminus \{v\}\) into \(q\) conics. Note that for every flock \(F = \{\pi_t\}\) there exist two maps \(f\) and \(g\) of \(GF(q)\) such that \(\pi_t\) has the ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Some causes of the variable shape of flocks of birds.
PLoS ONE, 2011 Flocks of birds are highly variable in shape in all contexts (while travelling, avoiding predation, wheeling above the roost). Particularly amazing in this respect are the aerial displays of huge flocks of starlings (Sturnus vulgaris) above the sleeping ...

Investigation of a Simple Model for Within-Flock Transmission of Scrapie. [PDF]
PLoS ONE, 2015 Genetic control programs for scrapie in sheep build on solid knowledge of how susceptibility to scrapie is modulated by the prion protein genotype at the level of an individual sheep. In order to satisfactorily analyze the effectivity of control programs
