Joint Feature Selection And Classification For Taxonomic Problems Within Fish Species Complexes, Yixin Chen, Shuqing Huang, Huimin Chen, Henry L. Bart

Huimin Chen

It is estimated that 90% of the world’s species are yet to be discovered and described. The main reason for the slow pace of new species description is that the science of taxonomy can be very laborious. To formally describe a new species, taxonomists have to manually gather and analyze data from large numbers of specimens and identify the smallest subset of external body characters that uniquely diagnose the new species as distinct from all its known relatives. In this paper, we present an automated feature selection and classification scheme using logistic regression with controlled false discovery rate to address …

Valency Dependence Of Polymorphism And Polyamorphism In Dna-Functionalized Nanoparticles, Wei Dai, Chia Wei Hsu, Francesco Sciortino, Francis W. Starr

Francis Starr

Nanoparticles (NP) functionalized with single-stranded DNA (ssDNA) offer a route to custom-designed, self- assembled nanomaterials with potentially unusual properties. The bonding selectivity of DNA guarantees one-to-one binding to form double-stranded DNA (dsDNA), and an appropriate base sequence results in head-to-tail binding linking NP into networks. We explore the phase behavior and structure of a model for NP functionalized with between 3 and 6 short ssDNA through simulations of a coarse-grained molecular model, allowing us to examine both the role of the number of attached strands (valency) and their relative orientations. The NP assemble into networks where the number of NP …

How A Bayesian Might Estimate The Distribution Of Cronbach’S Alpha From Ordinal-Dynamic Scaled Data A Case Study Measuring Nursing Home Resident Quality Of Life, Byron J. Gajewski, Diane K. Boyle, Sarah Thompson

Diane Kay Boyle PhD, RN, FAAN

We demonstrate the utility of a Bayesian based approach for calculating intervals of Cronbach’s alpha from a psychological instrument having ordinal responses with a dynamic scale. A small number of response options on an instrument will cause traditional-based interval estimates to be biased. Ordinal-based solutions are problematic because there is no clear mechanism for handling the dynamic scale. One way to remedy the bias is to adjust with a Bayesian approach. The Bayesian approach adjusts the bias and allows theoretically simple calculations of Cronbach’s alpha and intervals. We demonstrate the calculations of the Bayesian approach while at the same time …

Self-Assembly, Condensation, And Order In Aqueous Lyotropic Chromonic Liquid Crystals Crowded With Additives, Luana Tortora, Heung-Shik Park, Shin-Woong Kang, Victoria Savaryn, Seung-Ho Hong, Konstantine Kaznatcheev, Daniele Finotello, Samuel Sprunt, Satyendra Kumar, Oleg Lavrentovich

Satyendra Kumar

Dense multicomponent systems with macromolecules and small solutes attract a broad research interest as they mimic the molecularly crowded cellular interiors. The additives can condense and align the macromolecules, but they do not change the degree of covalentpolymerization. We chose a lyotropic chromonic liquid crystal with reversibly and non-covalently assembled aggregates as a much softer system, reminiscent of “living polymers”, to demonstrate that small neutral and charged additives cause condensation of aggregates with ensuing orientational and positional ordering and nontrivial morphologies of phase separation, such as tactoids and toroids of the nematic and hexagonal columnar phase coexisting with the isotropic …

Impact Of A Large Medical Waste Incinerator On Air Quality, Robert Oleniacz

Robert Oleniacz

In the paper, an assessment of the compliance with air emission limit values and the impact on air quality of one of the largest medical waste incinerators in Poland, with a total capacity of about 300 kg/h (two incineration lines) is presented. The assessment took the results of continuous and periodic measurements of emissions in the plant’s installation over a period of 12 months’ operation into account. For this period, a calculation was performed for the spread of air pollutants emitted by the two operating incineration lines. According to the analysis and calculations, the analysed medical waste incineration plant does …

A Novel Peer-To-Peer Sms Security Solution Using A Hybrid Technique Of Ntru And Aes-Rijndael, Miss Laiha Mat Kiah

Miss Laiha Mat Kiah

Short message service (SMS) is a very popular and easy to use communications technology for mobile phone devices. Originally, this service was not designed to transmit secured data, so the security was not an important issue during its design. Yet today, it is sometimes used to exchange sensitive information between communicating parties. This paper proposes an alternative solution that provides a peer-to-peer SMS security that guarantees provision of confidentiality, authentication, integrity and non-repudiation security services. A hybrid cryptographic scheme has been used which combines the NTRU and AES-Rijndael algorithms to achieve more robust functionality. For implementation, a mobile information device …
