Inductive Game Theory and the Dynamics of Animal Conflict

Conflict destabilizes social interactions and impedes cooperation at multiple scales of biological organization. Of fundamental interest are the causes of turbulent periods of conflict. We analyze conflict dynamics in an monkey society model system. We develop a technique, Inductive Game Theory, to extract directly from time-series data the decision-making strategies used by individuals and groups. This technique uses Monte Carlo simulation to test alternative causal models of conflict dynamics. We find individuals base their decision to fight on memory of social factors, not on short timescale ecological resource competition. Furthermore, the social assessments on which these decisions are based are triadic (self in relation to another pair of individuals), not pairwise. We show that this triadic decision making causes long conflict cascades and that there is a high population cost of the large fights associated with these cascades. These results suggest that individual agency has been over-emphasized in the social evolution of complex aggregates, and that pair-wise formalisms are inadequate. An appreciation of the empirical foundations of the collective dynamics of conflict is a crucial step towards its effective management

(1-Naphthyl­meth­yl)ammonium chloride

The reaction of 1-naphthyl­methyl­amine and hydro­chloric acid in a 1:1 molar ratio resulted in the formation of the 1:1 proton-transfer compound, C11H12N+·Cl−. In the crystal, the ions are linked by N—H⋯Cl hydrogen bonds into a sheet pattern in the ab plane such that each Cl− ion is bonded to three NH groups from the naphthylmethylammonium ion

Methyl (Z)-2-{[N-(2-formyl­phen­yl)-4-methyl­benzene­sulfonamido]­meth­yl}-3-phenyl­prop-2-enoate

In the title compound, C25H23NO5S, the sulfonyl-bound benzene ring forms dihedral angles of 37.2 (1) and 67.0 (1)°, respectively, with the formyl­phenyl and phenyl rings. The mol­ecular conformation is stabilized by an intra­molecular C—H⋯π inter­action. In the crystal, mol­ecules are linked by C—H⋯O hydrogen bonds, forming a two-dimensional network in the (110) plane in which R 4 4(38) ring motifs are generated

N-(4-Sulfamoylphen­yl)acetamide

In the title compound, C8H10N2O3S, the dihedral angle between the acetamide group and the benzene ring is 15.59 (12)° and the amino group is close to being perpendicular to the benzene ring [N—S—Car—Car (ar = aromatic) torsion angle = 109.4 (2)°]. In the crystal, mol­ecules are linked into supra­molecular tubes parallel to [001] by amine–amide N—H⋯O inter­actions and these are connected into the three-dimensional architecture by amide–sulfonamide N—H⋯O hydrogen bonds. The crystal studied was a racemic twin

Aqua­(2,2′-bipyridine-κ2 N,N′)(3,5-dinitro­benzoato-κO 1)copper(II) tetra­hydro­furan monosolvate

The title complex, [Cu(C7H3N2O6)2(C10H8N2)(H2O)]·C4H8O, features a penta­coordinate CuII atom bound by two monodentate carboxyl­ate ligands, a bidentate 2,2′-bipyridine mol­ecule [dihedral angle between pyridine rings = 5.0 (2)°] and a water mol­ecule. The resulting N2O3 donor set defines a distorted square-pyramidal geometry with the coordinated water mol­ecule in the apical position. In the crystal, the presence of O—Hw⋯Oc (w = water and c = carbon­yl) hydrogen bonding leads to the formation of a supra­molecular chain propagating along the c axis, which associates into a double chain via C—H⋯ O and π–π contacts between pyridyl rings [centroid–centroid distance = 3.527 (3) Å]. The solvent mol­ecules, which are disordered over two orientations in a 0.678 (11):0.322 (11) ratio, occupy voids defined by the complex mol­ecules and are held in place via C—H⋯O inter­actions

Translation and manipulation of silicon nanomembranes using holographic optical tweezers

We demonstrate the use of holographic optical tweezers for trapping and manipulating silicon nanomembranes. These macroscopic free-standing sheets of single-crystalline silicon are attractive for use in next-generation flexible electronics. We achieve three-dimensional control by attaching a functionalized silica bead to the silicon surface, enabling non-contact trapping and manipulation of planar structures with high aspect ratios (high lateral size to thickness). Using as few as one trap and trapping powers as low as several hundred milliwatts, silicon nanomembranes can be rotated and translated in a solution over large distances

Aromatic oligoesters as novel helix mimetic scaffolds

The design, synthesis, and conformational analysis of a novel aromatic oligoester helix mimetic scaffold is reported. A range of amino acid-type side-chain functionality can be readily incorporated into monomer building blocks over three facile synthetic steps. Analysis of representative dimers revealed a stable conformer capable of effective mimicry of a canonical α-helix and the scaffold was found to be surprisingly stable to degradation in aqueous solutions at acidic and neutral pH
