One Receptor Show: Evaluation of Feature Extraction Methods for a Single Gas Sensor Based on α-Tocopherol-Substituted Zinc Phthalocyanine.

A consistent part of gas sensor research activities aims to improve sensing performances by synthesizing new sensing materials, improving the selection of elements in arrays, and optimizing the feature extraction and classification algorithms. This paper combines most of these aspects to confer selectivity to a low-selectivity sensor by using feature extraction algorithms applied to the sensor response kinetics. Several algorithms were employed to represent the kinetic behavior of the sensor response during the adsorption and desorption phases.

Identification and expression analysis of phosphate transporter (PHT) genes in Brachypodium distachyon in response to phosphorus deficiency.

Phosphorus (P) is a macronutrient that plays a crucial role in critical plant functions. Phosphate transporters (PHTs) ensure the acquisition and translocation of Pi in the plant, thereby playing a key role in maintaining normal plant growth under Pi deficiency conditions. In Brachypodium distachyon, the grass model system, the function of individual PHT genes, remains largely unknown.

Systematic analysis of Prx genes in the Brachypodium genus and their expression pattern under abiotic constraints.

Peroxiredoxins (Prx) are ubiquitous peroxidases required for the removal of excess free radicals produced under stress conditions. Peroxiredoxin genes (Prx) in the Brachypodium genus were identified using bioinformatics tools and their expression profiles were determined under abiotic stress using RT-qPCR. The promoter regions of Prx genes contain several cis-acting elements related to stress response.

Genetic variability of morpho-physiological response to phosphorus deficiency in Tunisian populations of Brachypodium hybridum.

Brachypodium hybridum (Poaceae) is widely distributed in the dry environments in Mediterranean basin, due to its high tolerance to drought. Investigating the natural variation of B. hybridum in response to environmental stresses is crucial for unraveling the genetic network of its stress tolerance.

Variability in response to salinity stress in natural Tunisian populations of Hordeum marinum subsp. marinum.

Soil salinity is one of the most serious environmental factors affecting crop productivity around the world. In this study, we analysed morpho-physiological variation in responses to salt stress in Tunisian populations of Hordeum marinum subsp. marinum.

Understanding the population genetic structure of coastal species (Cakile maritima): seed dispersal and the role of sea currents in determining population structure.

The nature and extent of long-distance seed dispersal are currently poorly understood, largely due to the inherent difficulty in detecting such a phenomenon. Genetic methods provide one of the few general approaches that offer the potential to accurately address this issue. Phenotypic and allozymic approaches were applied to characterize inter-population seed dispersal of the sea rocket (Cakile maritima, Brassicaceae), a glabrous and succulent annual herb.

Differential pulse polarography of cadmium-and lead-urate and adsorptive stripping voltammetric determination of uric acid.

The complex formation between uric acid and zinc, cadmium and lead ions has been investigated using differential pulse polarography in 0.01M NaNO(3). It is found that the complexes formed by Cd(II) and Pb(II) ions with uric acid have the stoichiometry of 1:2 and the logarithmic values of the apparent stability constant are 9.

Activity levels as a dimension of temperament in toddlers: its relevance for the organismic specificity hypothesis.

The objective of the present study was to follow up on hypotheses derived from earlier research on activity level as a possible mediator between environment and development. Of particular theoretical interest was the organismic specificity hypothesis, which states that early experiences differentially influence development because the impact of the environment is mediated by individual differences in the organism. Subjects were 52 15-month-old toddlers who were observed in their homes 6 times over a 4-week period.

A small adrenocortical carcinoma with aggressive behavior. An evaluation of criteria for malignancy.

Adrenocortical carcinoma is an unusual tumor that tends to be larger than 100 g at diagnosis. Malignant adrenocortical tumors of less than 50 g have been reported rarely. We studied a small adrenocortical carcinoma that weighed 40 g and metastasized 3 1/2 years following bilateral adrenalectomy.

Surgical treatment of early-stage carcinoma of the oral tongue--wound adjuvant treatment be beneficial?

A group of 97 patients with clinical stage I and stage II squamous carcinoma of the oral tongue, treated by partial glossectomy alone, has been reviewed to define prognostic indicators. Sixty-seven patients were staged T1N0 and 30 were T2N0. Disease recurred in 28 patients (27%) and the most common site of failure was the ipsilateral neck (21%).
