Polymerisable octahedral rhenium cluster complexes as precursors for photo/electroluminescent polymers

New polymerisable photoluminescent octahedral rhenium cluster complexes trans-[{Re₆Q₈}(TBP)₄VB)₂] (Q = S or Se; TBP – p-tert-butylpyridine; VB – vinyl benzoate) have been synthesised, characterised and used to construct rhe-nium cluster-organic polymer hybrid materials. These novel polymer systems are solution-processable and the rhenium clusters retain their photoluminescent properties within the polymer environment. Notably, when the rhenium cluster complexes are incorporated into the matrix of the electroluminescent polymer poly(N-vinylcarbazole), the resultant cluster polymer hybrid combined properties of both components and was used successfully in the construc-tion of a polymer light emitting diode (PLED). These prototype devices are the first PLEDs to incorporate octahedral rhenium clusters and provide the first direct evidence of the electroluminescent properties of rhenium clusters and indeed, to the best of our knowledge, of any member of the family of 24-electron hexanuclear cluster complexes of molybdenum, tungsten or rhenium

Data-Efficient Classification of Birdcall Through Convolutional Neural Networks Transfer Learning

Deep learning Convolutional Neural Network (CNN) models are powerful classification models but require a large amount of training data. In niche domains such as bird acoustics, it is expensive and difficult to obtain a large number of training samples. One method of classifying data with a limited number of training samples is to employ transfer learning. In this research, we evaluated the effectiveness of birdcall classification using transfer learning from a larger base dataset (2814 samples in 46 classes) to a smaller target dataset (351 samples in 10 classes) using the ResNet-50 CNN. We obtained 79% average validation accuracy on the target dataset in 5-fold cross-validation. The methodology of transfer learning from an ImageNet-trained CNN to a project-specific and a much smaller set of classes and images was extended to the domain of spectrogram images, where the base dataset effectively played the role of the ImageNet.Comment: Accepted for IEEE Digital Image Computing: Techniques and Applications, 2019 (DICTA 2019), 2-4 December 2019 in Perth, Australia, http://dicta2019.dictaconference.org/index.htm

Hexaazide octahedral molybdenum cluster complexes: synthesis, properties and the evidence of hydrolysis

This article reports the synthesis, crystal structure of new molybdenum hexaazide cluster complex (ⁿBu₄N)₂[{Mo₆I₈}(N₃)₆] (3) and comparison of its photophysical and electrochemical properties to those of earlier reported analogues (ⁿBu₄N)₂[{M₆X₈}(N₃)₆] (X = Cl, Br). Additionally, the dimerisation of 3 as a result of hydrolysis was revealed by mass spectrometry and single crystal X-Ray diffraction. Indeed, the structurally characterised compound (ⁿBu₄N)₄[{Mo₆I₈}(N₃)₅)₂O] represents the first example of oxo-bridged dimer of octahedral molybdenum clusters complexes

Genes involved in the regulation of vascular homeostasis determine renal survival rate in patients with chronic glomerulonephritis

In this study, we analyzed association of genes of vascular homeostasis with hypertension and renal survival of CGN patients. The study sample included 238 patients with CGN and 304 healthy subjects of population control. Ten polymorphisms of ten genes of vascular homeostasis were genotyped through polymerase chain reaction (PCR), restriction fragment length polymorphism (RFLP) analysis and TaqMan assays. Association of the genotypes with renal survival was analyzed by the Kaplan-Meier estimato

Estimate or the effectiveness of intelligent information system of early diagnosis and prognosis of cardiovascular disease

This article describes a new approach to the implementation of the training program of risk probability of coronary heart disease (CHD) remote evaluation. It describes an example of training sample formation based on the statistical analysis of medical data. The proposed solution will allow medical personnel to carry out the personification of cardiac services and first of all, preventive orientation. Also a method for assessing the effectiveness of the program of expert system "ARM-Cardiologist" on the results of ongoing clinical trials is providedyesБелгородский государственный университе

The optimization of the system of taxpayers’ state registration using road mapping method

In the state registration of taxpayers is the basis for creation of Unified State Register of Taxpayers (as to legal entities and individual entrepreneurs), which allows controlling completeness and timeliness of taxes’ payment and, consequently, providing formation of budget. The paper analyses legal framework for regulation of taxpayers’ registration, distinguishes the particularities of registration of organizations and private persons (individual entrepreneurs). There is also an analysis of applicable practice of taxpayers’ registration in Russia and the Republic of Mordovia. The positive trends (formation of unified federal registration base for taxpayers’ recording; openness and general availability of information about all taxpayers registered on the territory of Russia; wide list of services on state registration that are rendered by tax authorities to taxpayers; transition to the regime of “single window” in interaction between registering structures; prejudicial regulation of appeal of decisions on state registration of legal entities and individual entrepreneurs) and system problems (impossibility of use of unified registration number of a taxpayer for coordination of information about him in different state organizations; irrelevance and incompleteness of information contained in databases of different state institutions; conscious evasion of taxpayers of performance of tax obligations on registration; difficulty of timely detection of short-lived companies; significant volume of migrant organizations; insufficient technical and program support of regional tax inspections) linked to registration processes are elicited.peer-reviewe

Clinical-functional changes of myocardium after percutaneous coronary interventions in patients with chronic heart failure

The study aimed to evaluate the results of clinical and functional changes in the left ventricular myocardium in patients with CHF after transluminal balloon angioplasty (TLBAP) of the coronary arteries with stenting of the coronary arteries during the observed period and to study the safety of surgical intervention in these patients. The study showed a statistically significant decrease in the functional class of CHF after percutaneous coronary intervention, followed by an improvement in the diastolic function (E/A) of the LV in the course of the observed perio

Luminescent coordination polymers based on Ca²⁺ and octahedral cluster anions [{M₆Clⁱ₈}Clᵃ₆}²⁻ (M = Mo, W) : synthesis and thermal stability studies

Luminescent coordination polymers (CPs) based of inexpensive stable precursors are attractive materials for applications. Here we report the synthesis and evaluation of the stability and photophysical characteristics of the first examples of phosphorescent CPs based on octahedral molybdenum and tungsten cluster anions. Specifically 1D CP trans-[{Ca(OPPh₃)₄}{{M₆Clⁱ₈}Clᵃ₆}]∞ (M = Mo, W) can be obtained either directly at increased temperature or via intermediate phases [cis-Ca(OPPh₃)₄(H₂O)₂][{M₆Clⁱ₈}Clᵃ₆]∙2CH₃CN that are stable at room-temperature, but convert to the titled CP at temperatures above 100 °C
