A Note on Upper Bounds for Some Generalized Folkman Numbers

Discussiones Mathematicae Graph Theory, 2019
We present some new constructive upper bounds based on product graphs for generalized vertex Folkman numbers. They lead to new upper bounds for some special cases of generalized edge Folkman numbers, including the cases Fe(K3, K4 − e; K5) ≤ 27 and Fe(K4 −

Restricted size Ramsey number for P3 versus cycle

Electronic Journal of Graph Theory and Applications, 2020
Let F, G and H be simple graphs. We say F → (G,H) if for every 2-coloring of the edges of F there exists a red copy of G or a blue copy of H in F. The Ramsey number r(G,H) is defined as r(G,H) = min{|V(F)|: F → (G,H)}, while the restricted size Ramsey ...

Impact of cystic fibrosis transmembrane conductance regulator modulator therapies on liver stiffness and liver enzymes: An observational perspective single‐center cohort study

JPGN Reports, EarlyView.
Abstract Objectives The efficacy of cystic fibrosis transmembrane conductance regulator (CFTR)‐modulator therapies in preventing or ameliorating cystic fibrosis liver disease (CFLD) by correcting CFTR in cholangiocytes is not well‐documented. This study aimed to assess liver function during CFTR‐modulators.

A twofold development and demise of pine stands in the Netherlands during the Allerød interstadial: two hypotheses to explain a link to climate change recorded in Greenland ice

Journal of Quaternary Science, EarlyView.
ABSTRACT The second half of the Allerød interstadial in the Netherlands is characterised by pine forest. Excavated trunks of 165 pine trees at Leusden‐Den Treek in the central Netherlands (LETR16) were dated by dendrochronology and radiocarbon. Two chronologically separated pine forest phases occurred during relatively warm periods as recorded in ...

Insights into Red Deer Ecology during the Late Epigravettian: New isotopic evidence from Riparo Tagliente (Italian Prealps)

Journal of Quaternary Science, EarlyView.
Abstract The transition from the Last Glacial Maximum to the Late Glacial marked a shift from the cold conditions of Greenland Stadial‐2 (GS‐2) to the warmer phases of Greenland Interstadial‐1 (GI‐1), enabling the reoccupation of Alpine regions by Late Palaeolithic hunter‐gatherers.

The Ramsey numbers of fans versus a complete graph of order five

Electronic Journal of Graph Theory and Applications, 2014
For two given graphs $F$ and $H$, the Ramsey number $R(F,H)$ is the smallest integer $N$ such that for any graph $G$ of order $N$, either $G$ contains $F$ or the complement of $G$ contains $H$.

Reconstructing the Holocene explosive eruptive history of the Erciyes volcano (Turkey) using proximal and distal tephra records

Journal of Quaternary Science, EarlyView.
ABSTRACT Mount Erciyes, the largest active volcano of Central Anatolia (Turkey), erupted explosively during the Holocene, producing the Karagüllü, Perikartin and Dikkartin tuff rings. Even though major cities like Kayseri and its ~1 million residents sit directly on these pyroclastic deposits, the timing and magnitude of the explosive eruptions have ...

Large‐scale phenotyping of physical and antioxidant traits in peach and apricot cultivars

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Peach and apricot are valued for their sensory attributes and nutritional value; however large‐scale evaluations of fruit quality and antioxidant‐related traits remain limited. This study aimed to quantify phenotypic diversity and examine relationships between fruit quality and antioxidant traits in 100 peach and 32 apricot ...

Potentially morally injurious events and posttraumatic stress symptom change across the military‐to‐civilian transition: A prospective study

Journal of Traumatic Stress, EarlyView.
Abstract This prospective study examined whether exposure to potentially morally injurious events (PMIEs), specifically self‐attributed transgressions, other‐attributed transgressions, and experiences of betrayal, predicted change in posttraumatic stress symptoms (PTSS) and reintegration difficulty during the military‐to‐civilian transition (MCT).
