The expected potential of hadronic PeVatron searches with spectral γ-ray data from the Southern Wide-field Gamma-ray Observatory
Angüner, Ekrem Oğuzhan; Ergin, Tülün (2024-06-01)
The presence of a spectral softening, occurring at ∼3 PeV energies, seen in the local cosmic-ray energy spectrum provides an evidence that our Galaxy hosts astrophysical objects, known as ’hadronic PeVatrons’, that are cap...
Noncoprime action of a cyclic group
Ercan, Gülin; Güloğlu, İsmail Ş. (2024-04-01)
Let A be a finite nilpotent group acting fixed point freely on the finite (solvable) group G by automorphisms. It is conjectured that the nilpotent length of G is bounded above by ℓ(A), the number of primes dividing the or...
Temperature-dependent tuning of band gap of Fe3O4 nanoparticles for optoelectronic applications
Delice, S.; Isik, M.; Hasanlı, Nızamı (2024-04-01)
We have investigated structural, morphological and temperature dependent absorption characteristics of Fe3O4 nanoparticles. X-ray diffraction pattern exhibited six diffraction peaks belonging to the cubic phase structure w...
MAD-DAX: Anger and driver behaviours on the road
Öztürk, İbrahim; Bıçaksız, Pınar; Üzümcüoğlu, Yeşim; Özkan, Türker (2024-04-01)
Anger is a common emotion in everyday life, and in the context of driving, the experience of greater anger has been positively associated with aggressive behaviour, near-misses and crashes. Although the effect of anger on ...
Layer-by-layer assembly of chitosan/alginate thin films containing Salmonella enterica bacteriophages for antibacterial applications
Tidim, Gökçe; Guzel, Mustafa; Soyer, Yeşim; Erel Göktepe, İrem (2024-03-15)
The emergence of antibiotic resistant bacteria and the ineffectiveness of routine treatments inspired development of alternatives to biocides for antibacterial applications. Bacteriophages are natural predators of bacteria...
Nilpotent residual of a finite group
Rodrigues, Eliana; de Melo, Emerson; Ercan, Gülin (2024-03-01)
Let F be a nilpotent group acted on by a group H via automorphisms and let the group G admit the semidirect product FH as a group of automorphisms so that CG(F)=1. We prove that the order of γ∞(G), the rank of γ∞(G) are bo...
Mass formulas for individual black holes in merging binaries
Ozkarsligil, Zeynep Tugce; Tekin, Bayram (2024-03-01)
We give formulas for individual black hole masses in a merger, by using Newtonian physics, in terms of the three measured quantities in the detector: the initial wave frequency f 1, the maximum detected frequency (chirp fr...
Lysosomal alkalinization in nutrient restricted cancer cells activates cytoskeletal rearrangement to enhance partial epithelial to mesenchymal transition
Hüsnügil, Hepşen Hazal; Güleç Taşkıran, Aliye Ezgi; Güderer, İsmail; Nehri, Leman Nur; Oral, Göksu; Menemenli, Nazlı Şevval; Özcan, Özün; Noghreh, Ariana; AKYOL, AYTEKİN; Banerjee, Sreeparna (2024-03-01)
Introduction: Nutrient restriction in cancer cells can activate a number of stress response pathways for cell survival. We aimed to determine mechanistically how nutrient depletion in colorectal cancer (CRC) cells leads to...
A partial epithelial-mesenchymal transition signature for highly aggressive colorectal cancer cells that survive under nutrient restriction
Pastorino, Gil A; Sheraj, Ilır; Huebner, Kerstin; Ferrero, Giulio; Kunze, Philipp; Hartmann, Arndt; Hampel, Chuanpit; Hüsnügil, Hepşen Hazal; Maiuthed, Arnatchai; Gebhart, Florian; Schlattmann, Fynn; Gulec Taskiran, Aliye Ezgi; Oral, Goksu; Palmisano, Ralph; Pardini, Barbara; Naccarati, Alessio; Erlenbach-Wuensch, Katharina; Banerjee, Sreeparna; Schneider-Stock, Regine (2024-03-01)
Partial epithelial-mesenchymal transition (p-EMT) has recently been identified as a hybrid state consisting of cells with both epithelial and mesenchymal characteristics and is associated with the migration, metastasis, an...
Advanced technologies in biodegradable packaging using intelligent sensing to fight food waste
Jafarzadeh, Shima; Yildiz, Zeynep; Yildiz, Pelin; Strachowski, Przemyslaw; Forough, MEHRDAD; Esmaeili, Yasaman; Naebe, Minoo; Abdollahi, Mehdi (2024-03-01)
The limitation of conventional packaging in demonstrating accurate and real-time food expiration dates leads to food waste and foodborne diseases. Real-time food quality monitoring via intelligent packaging could be an eff...

SETD3 regulates endoderm differentiation of mouse embryonic stem cells through canonical Wnt signaling pathway.
Alganatay, Ceren; Balbasi, Emre; Tuncbag, Nurcan; Sezginmert, Dersu; Terzi Çizmecioğlu, Nihal (2024-02-29)
With self- renewal and pluripotency features, embryonic stem cells (ESCs) provide an invaluable tool to investigate early cell fate decisions. Pluripotency exit and lin-eage commitment depend on precise regulation of...
LS-14 test suite for long sequences
Akcengiz, Ziya; Aslan, Melis; Doğanaksoy, Ali; Sulak, Fatih; Uğuz, Muhiddin (2024-02-29)
Random number sequences are used in many branches of science. Because of many technical reasons and their practicality, pseudo random sequences are usually employed in place of true number sequences. Whether a sequence gen...
Revealing defect centers in PbWO4 single crystals using thermally stimulated current measurements
Isik, M.; Hasanlı, Nızamı (2024-02-28)
The trap centers have a significant impact on the electronic properties of lead tungstate (PbWO4), suggesting their crucial role in optoelectronic applications. In the present study, we investigated and revealed the presen...
Competing Intermolecular and Molecule-Surface Interactions: Dipole-Dipole-Driven Patterns in Mixed Carborane Self-Assembled Monolayers
White, Katherine E.; Avery, Erin M.; Cummings, Edison; Hong, Zixiang; Langecker, Jens; Vetushka, Aliaksei; Dušek, Michal; Macháček, Jan; Višnák, Jakub; Endres, Jan; Bastl, Zdeněk; Yılmaz, Ayşen; Alexandrova, Anastassia N.; Baše, Tomáš; Weiss, Paul S. (2024-02-27)

Constraining the Compression: Thermodynamic Depth and Composition
Davoody Benı, Majıd (2024-02-22)
This paper examines Bird's account of restricted compositionality in terms of compression of information. Additionally, this paper proposes an alternative perspective (to Bird's) that links compositionality to the Free Ene...
Exciton related nonlinear optical properties of a quantum wire
Ustoglu Unal, V.; Tomak, Mehmet; Zorlu, O.; Aksahin, E. (2024-02-15)
A considerable amount of work is done on nonlinear optical properties in quantum wells and dots. However, relatively fewer work is done on both quantum well wires and the excitonic effects. This work analyzes the excitonic...
