 Microfluidic Flow of Cholesteric Liquid Crystals / Wiese, Oliver ; Marenduzzo, Davide ; Henrich, Oliver We explore the rheology and flow-induced morphological changes of cholesteric liquid crystal patterns subject to Poiseuille flow within a slab geometry, and under different anchoring conditions at the wall. Our focus is particularly on the behaviour of Cholesteric Fingers of the first kind and of Blue Phase II.

 Colloidal Synthesis of Strongly Fluorescent CsPbBr3 Nanowires with Width Tunable down to the Quantum Confinement Regime / Imran, Muhammad ; Di Stasio, Francesco ; Dang, Zhiya ; Canale, Claudio ; Khan, Ali Hossain ; Shamsi, Javad ; Brescia, Rosaria ; Prato, Mirko ; Manna, Liberato We report the colloidal synthesis of strongly fluorescent CsPbBr3 perovskite nanowires (NWs) with rectangular section and with tuneable width, from 20 nm (exhibiting no quantum confinement, hence emitting in the green) down to around 3 nm (in the strong quan-tum-confinement regime, emitting in the blue), by introducing in the synthesis a short acid (octanoic acid or hexanoic acid) together with alkyl amines (octylamine and oleylamine). Temperatures below 70 {\deg}C promoted the formation of monodisperse, few unit cell thick NWs that were free from byproducts.

 Robustness of flight leadership relations in pigeons / Flack, Andrea ; Ákos, Zsuzsa ; Nagy, Máté ; Vicsek, Tamás ; Biro, Dora Collective animal movements produce spectacular natural phenomena that arise from simple local interactions among group members. Flocks of homing pigeons, Columba livia, provide a useful model for the study of collective motion and decision making.

 Bursts of activity in collective cell migration / Chepizhko, Oleksandr ; Giampietro, Costanza ; Mastrapasqua, Eleonora ; Nourazar, Mehdi ; Ascagni, Miriam ; Sugni, Michela ; Fascio, Umberto ; Leggio, Livio ; Malinverno, Chiara ; Scita, Giorgio et al. Dense monolayers of living cells display intriguing relaxation dynamics, reminiscent of soft and glassy materials close to the jamming transition, and migrate collectively when space is available, as in wound healing or in cancer invasion. Here we show that collective cell migration occurs in bursts that are similar to those recorded in the propagation of cracks, fluid fronts in porous media and ferromagnetic domain walls.

 The effect of temperature dependent tissue parameters on acoustic radiation force induced displacements / Suomi, Visa ; Han, Yang ; Konofagou, Elisa ; Cleveland, Robin Multiple ultrasound elastography techniques rely on acoustic radiation force (ARF) in monitoring high-intensity focused ultrasound (HIFU) therapy. However, ARF is dependent on tissue attenuation and sound speed, both of which are also known to change with temperature making the therapy monitoring more challenging.

 Combination with anti-tit-for-tat remedies problems of tit-for-tat / Yi, Su Do ; Baek, Seung Ki ; Choi, Jung-Kyoo One of the most important questions in game theory concerns how mutual cooperation can be achieved and maintained in a social dilemma. In Axelrod's tournaments of the iterated prisoner's dilemma, Tit-for-Tat (TFT) demonstrated the role of reciprocity in the emergence of cooperation.

 Activation cross sections of proton and deuteron induced nuclear reactions on holmium and erbium, related to the production of $^{161}$Er and $^{160}$Er medical isotopes / Tárkányi, F ; Ditrói, F ; Takács, S ; Hermanne, A ; Baba, M Experimental excitation functions for long-lived products in proton induced reactions were measured with the activation method in the 37-65 MeV energy range on natural holmium. Stacked foil irradiation technique and high resolution gamma spectrometry were used in order to measure cross-section data for the production of $^{161}$Er, $^{160}$Er and $^{159,157}$Dy.

 Isoperimetric Inequalities and Magnetic Fields at CERN / McInnes, Brett We discuss the generalization of the classical isoperimetric inequality to asymptotically hyperbolic Riemannian manifolds. It has been discovered that the AdS/CFT correspondence in string theory requires that such an inequality hold in order to be internally consistent.

 Momentum transfer dependence of generalized parton distributions / Sharma, Neetika We revisit the model for parametrization of momentum dependence of nucleon generalized parton distributions in the light of recent MRST measurements of parton distribution functions. Our parametrization method with minimum set of free parameters give a sufficiently good description of data for Dirac and Pauli electromagnetic form factors of proton and neutron at small and intermediate values of momentum transfer.

 ${\Upsilon}(1S)$ ${\to}$ $B_{c}{\pi}$, $B_{c}K$ decays with perturbative QCD approach / Sun, Junfeng ; Li, Qingxia ; Yang, Yueling ; Li, Haiyan ; Chang, Qin ; Zhang, Zhiqing With the potential prospects of the ${\Upsilon}(1S)$ at high-luminosity dedicated heavy-flavor factories, the bottom-changing ${\Upsilon}(1S)$ ${\to}$ $B_{c}{\pi}$, $B_{c}K$ weak decays are studied with the pQCD approach. It is found that branching ratio for the color-favored and CKM-favored ${\Upsilon}(1S)$ ${\to}$ $B_{c}{\pi}$ decay can reach up to ${\cal O}(10^{-11})$.
