Personality in the cockroach Diploptera punctata: Evidence for stability across developmental stages despite age effects on boldness

Despite a recent surge in the popularity of animal personality studies and their wide-ranging associations with various aspects of behavioural ecology, our understanding of the development of personality over ontogeny remains poorly understood. Stability over time is a central tenet of personality; ecological pressures experienced by an individual at different life stages may...

An alternate route to phosphorylating DegU of Bacillus subtilis using acetyl phosphate

Background Two-component signal transduction pathways allow bacteria to sense and respond to the environment. Typically such pathways comprise a sensor histidine kinase and a response regulator. Phosphorylation of the response regulator commonly results in its activation, allowing the protein to bind to target promoter elements to regulate transcription. Several mechanisms are...

An efficient analog Hamming distance comparator realized with a unipolar memristor array: a showcase of physical computing

Holder Qiangfei Xia R. Stanley Williams Xing Zhou J. JoshuaYang We propose and demonstrate a novel physical computing paradigm based on an engineered unipolar memristor that exhibits symmetric SET

A multicentre randomised controlled trial of reciprocal lung cancer peer review and supported quality improvement: results from the improving lung cancer outcomes project

Background:Results from the National Lung Cancer Audit demonstrate unexplained variation in outcomes. Peer review with supported quality improvement has been shown to reduce variation in other areas of health care but has not been formally tested in cancer multidisciplinary teams. The aim of the current study is to assess the impact of reciprocal peer-to-peer review visits with...

Variability in Seroprevalence of Rabies Virus Neutralizing Antibodies and Associated Factors in a Colorado Population of Big Brown Bats (Eptesicus fuscus)

In 2001–2005 we sampled permanently marked big brown bats (Eptesicus fuscus) at summer roosts in buildings at Fort Collins, Colorado, for rabies virus neutralizing antibodies (RVNA). Seroprevalence was higher in adult females (17.9%, n = 2,332) than males (9.4%, n = 128; P = 0.007) or volant juveniles (10.2%, n = 738; P<0.0001). Seroprevalence was lowest in a drought year with...

Intrinsic constrains on thermally-assisted memristive switching

We derived analytical formulas to estimate the effective thermal resistance of a metallic cylinder subjected to Joule heating, surrounded by an insulator and bounded by two constant temperature planes in order to estimate the temperature of the hottest point of the system. These solutions are especially relevant for modeling unipolar resistive switches (or memristive devices...

An ionic bottle for high-speed, long-retention memristive devices

We propose a new type of bipolar resistive switch or memristive device, based on an ionic bottle, which is characterized by both low switching energy and high state retention time. The ionic bottle is engineered such that image charges on metallic electrodes trap ions inside a semiconducting film when there is no applied bias voltage, but an external field can drive ions through...

Selective Heterogeneity in Exoprotease Production by Bacillus subtilis

Bacteria have elaborate signalling mechanisms to ensure a behavioural response that is most likely to enhance survival in a changing environment. It is becoming increasingly apparent that as part of this response, bacteria are capable of cell differentiation and can generate multiple, mutually exclusive co-existing cell states. These cell states are often associated with...

The Insect Pathogen Serratia marcescens Db10 Uses a Hybrid Non-Ribosomal Peptide Synthetase-Polyketide Synthase to Produce the Antibiotic Althiomycin

There is a continuing need to discover new bioactive natural products, such as antibiotics, in genetically-amenable micro-organisms. We observed that the enteric insect pathogen, Serratia marcescens Db10, produced a diffusible compound that inhibited the growth of Bacillis subtilis and Staphyloccocus aureus. Mapping the genetic locus required for this activity revealed a putative...
