Learning the travelling salesperson problem requires rethinking generalization
Abstract End-to-end training of neural network solvers for graph combinatorial optimization problems such as the Travelling Salesperson Problem (TSP) have seen a surge of interest recently, but...
Confinement in nonlocal interaction equations
We investigate some dynamical properties of nonlocal interaction equations. We consider sets of particles interacting pairwise via a potential W, as well as continuum descriptions of such systems. The typical potentials we...

Using R and Bioconductor for proteomics data analysis.
This review presents how R, the popular statistical environment and programming language, can be used in the frame of proteomics data analysis. A short introduction to R is given, with special emphasis on some of the features...
Trade-offs between the stepwise cost function and its linear approximation for the modular hub location problem
There exist situations where the transportation cost is better estimated as a function of the number of vehicles required for transporting a load, rather than a linear function of the load. This provides a stepwise cost...
Identifying neural substrates of competitive interactions and sequence transitions during mechanosensory responses in Drosophila.

Nervous systems have the ability to select appropriate actions and action sequences in response to sensory cues. The circuit mechanisms by which nervous systems achieve choice, stability and transitions between behaviors are...
Centrosome centering and decentering by microtubule network rearrangement.
The centrosome is positioned at the cell center by pushing and pulling forces transmitted by microtubules (MTs). Centrosome decentering is often considered to result from asymmetric, cortical pulling forces exerted in particular...
Magnesium hydride alkene insertion and catalytic hydrosilylation
The dimeric β-diketiminato magnesium hydride, [(BDI)MgH] 2, reacts at 80 °C with the terminal alkenes, 1-hexene, 1-octene, 3-phenyl-1-propene and 3,3-dimethyl-butene to provide the respective n-hexyl, n-octyl...
Organocalcium-mediated nucleophilic alkylation of benzene
The electrophilic aromatic substitution of a C–H bond of benzene is one of the archetypal transformations of organic chemistry. In contrast, the electron-rich p-system of benzene is highly resistant to reactions with...

Accounting for the Multiple Natures of Missing Values in Label-Free Quantitative Proteomics Data Sets to Compare Imputation Strategies.
Identification and analysis of serpin-family genes by homology and synteny across the 12 sequenced Drosophilid genomes.
Gene regulatory network inference from sparsely sampled noisy data
Abstract: The complexity of biological systems is encoded in gene regulatory networks. Unravelling this intricate web is a fundamental step in understanding the mechanisms of life and eventually developing efficient therapies to...
Calcium Hydride Reduction of Polycyclic Aromatic Hydrocarbons
A molecular calcium hydride effects the two electron reduction of polyaromatic hydrocarbons, including naphthalene (E0=−3.1 V).

Impact on product appeal of labeling wine and beer with (a) lower strength alcohol verbal descriptors and (b) percent alcohol by volume (%ABV)
Lower strength alcohol products may help reduce alcohol consumption and associated harms. This study assessed the impact of labeling wine and beer with different verbal descriptors denoting lower strength, with and without...
Dehydrohalogenation of halobenzenes and C(sp3)-X (X = F, OPh) bond activation by a molecular calcium hydride
The molecular calcium hydride, [(BDI)CaH]2(BDI¼HC{(Me)CN-2,6-i-Pr2C6H3}2), effects the slowhydrodehalogenation of C6H5X(X¼I, Br) to provide benzene and the respective dimeric calcium halides,[(BDI)CaX]2. Although a similar...
The sum-of-squares hierarchy on the sphere and applications in quantum information theory
Abstract: We consider the problem of maximizing a homogeneous polynomial on the unit sphere and its hierarchy of sum-of-squares relaxations. Exploiting the polynomial kernel technique, we obtain a quadratic improvement of the...
Formal conserved quantities for isothermic surfaces
Isothermic surfaces in Sn are characterised by the existence of a pencil ∇t∇∇t of flat connections. Such a surface is special of type d if there is a family p...
