Energy-efficient power allocation of two-hop cooperative systems with imperfect channel estimation (2015)

Recently, much attention has been paid to the green design of wireless communication systems using energy efficiency (EE) metrics that should capture all energy consumption sources to deliver the required data. In this paper, we formulate an accurate EE metric for cooperative two-hop systems that use the amplify-and-forward relaying scheme. Different from the existing research that assumes the availability of perfect channel state information (CSI) at the communication cooperative nodes, we assume a practical scenario, where training pilots are used to estimate the channels. The estimated CSI can be used to adapt the available resources of the proposed system in order to maximize the EE. Two estimation strategies are assumed namely disintegrated channel estimation, which assumes the availability of channel estimator at the relay, and cascaded channel estimation, where the relay is not equipped with channel estimator and only forwards the received pilot(s) in order to let the destination estimate the cooperative link. The channel estimation cost is reflected on the EE metric by including the estimation error in the signal-to-noise term and considering the energy consumption during the estimation phase. Based on the formulated EE metric, we propose an energy-aware power allocation algorithm to maximize the EE of the cooperative system with channel estimation. Furthermore, we study the impact of the estimation parameters on the optimized EE performance via simulation examples.

New Concepts of a Blood-Brain Barrier (1997)

edited by John Greenwood, David J. Begley, and Malcolm B. Segal, 331 pp., ill., New York, Plenum Press, 1995, $89.50

The blood-brain barrier normally protects brain cells from substances circulating in the blood. Disruption of the blood-brain barrier is important in the pathophysiology of many neurologic diseases, including multiple sclerosis, strokes, and infections. New Concepts of a Blood-Brain Barrier is a series of lectures from a conference held in 1994 in honor of Professor Michael W.B. Bradbury. Topics covered range from the development of the bloodbrain barrier to attempts at opening the barrier to treat brain tumors.

Outstanding effects on antithrombin activity of modified TBA diastereomers containing an optically pure acyclic nucleotide analogue (2014)

Herein, we report optically pure modified acyclic nucleosides as ideal probes for aptamer modification. These new monomers offer unique advantages in exploring the role played in thrombin inhibition by a single residue modification at key positions of the TBA structure.
THE CATEGORY «THE ONE» AND A MYSTICAL EXPERIENCE. HERMENEUTIC STRATEGY OF AN INTERPRETATION OF A MYSTICAL TEXT (2019)

The article contains the result of the comparative analysis of henological and mystical texts. This paper considers «The One» category in its relationship with a mystical experience. The author raises the question of finding a strategy for more complete understanding of the meaning of «The One» category when working with mystical text. This work considers mystical text as a text that simultaneously contains both the revealed «truth» and the personal experience of the mystic. As a result of the research, the author comes to the conclusion that if mystics had personal experience of The One, then The One cannot but be that thing that they themselves were. To some extent, «The One» category in a mystical text is an attempt of rational organisation of subjective experiences. Accordingly, the mystical text contains elements of the autobiographical text, which in turn authorises the use of the biographical approach when working with mystical text.
IMPROVEMENT OF THE BLENDING TECHNOLOGY OF MEDIUM DRY AND SEMI-SWEET WHITE TABLE WINES (2019)

The paper reviews the literature on the existing technologies of medium dry and semi-sweet table wines. The main problems of manufacturing this type of wines have been outlined, as well as how they are solved by domestic and foreign winemakers. The classical scheme of producing medium dry and semi-sweet wines allows retaining the aroma of a certain grape variety and obtaining quality wines, but it is not applied in Ukraine as it is technologically complicated and costly. The scheme that involves blending is far more economical, but does not allow retaining all the fine aromatic nuances of a variety. So, the article considers the ways of obtaining medium dry and semi-sweet wines using grape must that has been concentrated by freezing. It has been shown that this technology will allow retaining the valuable substances of the variety aroma and will be the basis for producing the highest-quality wines of this type. For the research, the following samples have been analysed: clarified must of the Rkatsiteli and Citronny Magaracha grape varieties, must concentrated by freezing, vacuum must, dry wine materials, and the medium dry white table wines made from them. In the musts and wines, the main physical and chemical characteristics have been studied (the mass concentrations of sugar, titrated acids, total and free sulphur dioxide), as well as some additional parameters (the pH, mass concentrations of phenolic substances, free and bound terpene alcohols, optical density with the wavelength 420 nm). The mass concentrations of volatile acids and the sensory characteristics of the wine materials and wines have been determined, too. The research has shown that in the medium dry wines obtained by cryotechnology, the concentrations of free terpene compounds increased from 1.01 mg/dm3 to 1.21 mg/dm3 in Rkatsiteli, and from 2.89 mg/dm3 to 3.24 mg/dm3 in Citronny Magaracha. The flavour and aroma improved substantially, too. So, the blending technology of producing medium dry and semi-sweet table wines using cryomust allows retaining, to the greatest possible degree, the bright and peculiar aroma of the grape variety, and obtaining the highest-quality wines of this type.
Reduction of the auto seismic component of error of a ballistic laser gravimeter by excitation of an induction-dynamic catapult from an AC voltage source (2021)

The purpose of the study is to analyse the influence of the excitation of an induction-dynamic catapult of a ballistic laser gravimeter from an AC voltage source at different frequencies on electromechanical indicators that provide a reduced value of the auto seismic component of error in measuring the gravitational acceleration g due to a decrease in the recoil force. A mathematical model of the gravimeter catapult when excited from an AC voltage source is proposed, taking into account the interrelated electrical, magnetic and mechanical processes. The nature of the electromechanical processes in the catapult of the gravimeter with such excitation has been established. It is shown that a phase shift occurs between the currents in active elements, as a result of which positive (repulsive) pulses of the electrodynamic force alternate with negative (attractive) pulses of force. A criterion for the efficiency of the gravimeter catapult has been introduced, taking into account the maximum value of push of the test body at the smallest values of the electrodynamic force and current of the inductor winding. It was found that the highest efficiency of the gravimeter catapult is provided at a frequency of 250 Hz, at which the catapult efficiency is 3.5 times higher than at a frequency of 50 Hz. It is shown that the transition from the method of excitation of an induction-dynamic catapult with one short pulse to excitation from an AC voltage source makes it possible to reduce the uncertainty in measuring the gravitational acceleration.
Fluorescence Anisotropy Assay for the Traceless Kinetic Analysis of Protein Digestion (2008)

A novel fluorescence polarization assay based on the natural fluorophore epicocconone has been developed. This assay allows the rapid and accurate determination of enzyme kinetic parameters as well as inhibition constants through the measurement of fluorescence anisotropy on the actual substrate of the protease. It takes advantage of epicocconone's ability to reversibly react with proteins to form an internal charge-transfer complex that is highly fluorescent. The protein-substrate is labeled in situ without the need for prior incubation and/or derivatization steps, which saves time and effort compared to methods employing specifically labeled protein-substrates. The assay can be carried out in 96- or 384-well plates, making it suitable for high-throughput applications in drug development and biotechnology.
Endophytic bacteria from tomato and chilli, their diversity and antagonistic potential againstRalstonia solanacearum (2011)

A total of 82 endophytic bacteria of tomato and chilli was isolated from different locations of tropical Islands of Andaman and Nicobar, India. Based on in vitro screening, 16 bacterial isolates that effectively inhibited Ralstonia solanacearum (a bacterial wilt pathogen) were characterised for their diversity and identified through Microbial Identification System (Biolog). Diversity analysed through BOX-PCR showed low similarity index among the antagonistic bacteria. Based on the in vitro antagonistic activities, the selected isolates were further characterised for siderophore, indole acetic acid production, phosphate solubilisation and other extracellular enzymes; it is found that most of the isolates were positive for these properties. The production of these metabolites may be responsible for the inhibition of the pathogen R. solanacearum. The isolates BECS3, BECS6 and BECS7 showed multiple attributes and demonstrated plant growth promotion properties through tomato- and chilli-based bioassay under greenhouse conditions. These bacterial inoculations were found to result in significant increase in root, shoot and biomass of both tomato and chilli. Hence, these isolates can be further formulated and used for field application.
Comparison of AZO, GZO, and AGZO Thin Films TCOs Applied for a-Si Solar Cells (2012)

This study prepared aluminum and gallium co-doped zinc oxide (AGZO) thin films using pulsed direct current magnetron sputtering, and studied the electrical properties, transmittance, effects of texturing, and applicability as the front contact for a-Si:H solar cells. Textured ZnO:Al (AZO) and ZnO:Ga (GZO) thin films were also compared with AGZO thin film to evaluate their performance as front contacts. Experimental results show that AGZO films with the highest figure of merit ϕTC value (24.64 × 10−3 Ω−1) were obtained at Al and Ga doping concentrations of 0.54 wt% and 1.165 wt%, respectively. The textured AGZO films used as the front contact in a-Si:H solar cells achieved the following results: VOC = 0.77 V, JSC = 16.5 mA/cm2, FF = 59%, and conversion efficiency of 7.53%. AZO and GZO films have better electrical properties than AGZO film; however, AGZO film has superior transmittance in the near-infrared (NIR) region and higher JSC, conversion efficiency and external quantum efficiency (EQE) than AZO and GZO films under a similar haze value.
Is really full right full left split liver transplantation a valuable tool to increase organ availability? (2013)

The gap between available liver grafts and the number of patients in need for liver transplantation represents an unsolved issue worldwide. To overcome this persistent disparity, which is of particular relevance for adult recipients, split liver transplantation (SLT) is one of the main resources utilized by liver transplant centers.

New simplified methods for patterning the rear contact of RP-PERC high-efficiency solar cells (2000)

New processing schemes for fabricating the rear contact pattern of the PERC-structure (passivated emitter and rear cell) are demonstrated. Both, thermally-grown silicon oxide (SiO/sub 2/) and plasma-deposited silicon nitride (SiN/sub x/) are used as the passivating rear layer. The first processing scheme utilizes plasma etching of the dielectric layer through a mask. The plasma process was optimized in order to reduce the damage in the silicon base of the cell. Efficiencies of 21.5% and 21.7% have been achieved for SiN/sub x/ and SiO/sub 2/ rear layers, respectively. The second approach uses a laser beam to remove the dielectric layer for the rear contact pattern. Efficiencies of 19.7% and 21.3% have been achieved for SiN/sub x/ and SiO/sub 2/ rear layers, respectively. Reference cells with the same front structure but conventionally processed rear (photo resist, wet-chemical etching) show only a slightly higher efficiency of 22.0% on cells with a SiO/sub 2/ passivation layer. This proves that both approaches have a very high potential.
Effects of low and high dose administration of bis(maltolato)oxovanadium(IV) on fa/fa Zucker rats (1996)

The fatty Zucker rat, characterized by obesity, hyperinsulinemia, hyperlipidemia, and mild hyperglycemia, has been suggested as an animal model of non-insulin-dependent diabetes mellitus. The present study examined the chronic dose-dependent effect of bis(maltolato)oxovanadium(IV), a potent insulin mimetic, in this animal model of diabetes. Chronic (6 weeks) oral administration of bis(maltolato)oxovanadium(IV) (0.06 mmol.kg-1.day-1, low dose study) was effective in reducing the hyperinsulinemia associated with the fatty Zucker rat model (termination insulin: lean, 82.8 +/- 21.6; fatty, 732 +/- 89.4; fatty treated, 336 +/- 126.6 pmol/L; p < 0.05). Pancreatic perfusion data indicated a significant improvement in insulin secretory function in the fatty rats. The dose dependency of this relationship was observed in the high dose study (0.128 mmol.kg-1.day-1 for 14 weeks), wherein bis(maltolato)oxovanadium(IV) treatment restored plasma insulin levels in the fatty rats to lean levels (termination insulin: lean, 199.2 +/- 17.4; fatty 660.6 +/- 12.6; fatty treated, 153.6 +/- 9.6 pmol/L; p < 0.05) and significantly improved insulin response to a glucose challenge. In addition, bis(maltolato)oxovanadium(IV) treatment (high dose study) ameliorated the age-dependent increase in blood pressure observed in fatty Zucker rats (systolic blood pressure: lean, 127 +/- 10; fatty, 176 +/- 5; fatty treated, 156 +/- 9 mmHg (1 mmHg = 133.3 Pa)). These data indicate that chronic oral administration of bis(maltolato)oxovanadium(IV) in the drinking water was effective in reducing hyperinsulinemia, insulin resistance, glucose intolerance, and hypertension in the fatty Zucker rat.
Tailor-made modeling and sway control of human posture riding on electrical wheelchair for comfort driving (2010)

This paper gives an advanced driving control system that considers sway suppression of a passenger's posture in an electrical wheelchair. We proposed a passenger model that considers the passenger's physical frame and seating condition. The passenger's seating condition is classified as upright, standard, or round-shouldered posture. The sway of a passenger with round-shouldered posture is smaller than that of a passenger with upright posture, and they can be represented by the proposed model. To suppress the sway of a wheelchair passenger's posture, the wheelchair driving pattern is optimized using the proposed passenger's posture model. The comfort of the passenger with respect to the proposed wheelchair driving is evaluated through experiments.
Separation of immortalization from tumor induction with polyoma large T mutants that fail to bind the retinoblastoma gene product. (1992)

The mouse polyomavirus encodes a tumor-suppressor gene inactivator in its large T protein and a proto-oncogene activator in its middle T protein. We have used site-directed mutagenesis to selectively inactivate the former function without affecting the latter. Two mutant viruses were constructed to encode altered large T proteins that fail to bind the retinoblastoma tumor-suppressor gene product pRB, along with normal small and middle T proteins. The pRB-binding mutants proved to be defective in immortalization of primary rat embryo fibroblasts by a variety of tests. Yet they proved capable of transforming both primary and established fibroblasts in culture. Most importantly, the inability of these mutants to bind pRB had little effect on their ability to induce tumors in mice. We conclude that induction of multiple tumor types in this system does not depend on large T-pRB interactions but rather on middle T-dependent pathways. In addition, the ability of this virus to immortalize cells in culture is not essential to its ability to induce tumors in the animal.

Central Regulation of Intestinal Motility by Somatostatin and Cholecystokinin Octapeptide (1982)

When injected continuously into the lateral ventricles of the rat, somatostatin increased the frequency of the migrating myoelectric complexes of the small intestine in a dose-related manner. A significant increase was obtained at a dose as low as 0.066 picomole per minute. In contrast, cholecystokinin octapeptide decreased the frequency of the migrating myoelectric complex of the small intestine or disrupted this pattern when injected into the lateral ventricle at rates of 0.073 to 0.23 picomole per minute. These findings support the hypothesis that somatostatin and cholecystokinin octapeptide act on central nervous system structures that are involved in the control of intestinal motility.

Epitope-coated polymer particles elicit neutralising antibodies against Plasmodium falciparum sporozoites (2021)

The current Malaria RTS,S vaccine is based on virus-like particles (VLPs) comprising the NANP repetitive epitopes from the cicumsporozoite protein (CSP) of Plasmodium falciparum. This vaccine has limited efficacy, only preventing severe disease in about 30% of vaccinated individuals. A more efficacious vaccine is urgently needed to combat malaria. Here we developed a particulate malaria vaccine based on the same CSP epitopes but using biopolymer particles (BPs) as an antigen carrier system. Specific B- and T-cell epitope-coated BPs were assembled in vivo inside an engineered endotoxin-free mutant of Escherichia coli. A high-yield production process leading to ~27% BP vaccine weight over biomass was established. The epitope-coated BPs were purified and their composition, i.e., the polymer core and epitope identity, was confirmed. Epitope-coated BPs were used alongside soluble peptide epitopes and empty BPs to vaccinate sheep. Epitope-coated BPs showed enhanced immunogenicity by inducing anti-NANP antibody titre of EC50 > 150,000 that were at least 20 times higher than induced by the soluble peptides. We concluded that the additional T-cell epitope was not required as it did not enhance immunogenicity when compared with the B-cell epitope-coated BPs. Antibodies specifically bound to the surface of Plasmodium falciparum sporozoites and efficiently inhibited sporozoite motility and traversal of human hepatocytes. This study demonstrated the utility of biologically self-assembled epitope-coated BPs as an epitope carrier for inclusion in next-generation malaria vaccines.
Audio-video synchronous coding based on motion estimation in H.264 (2012)

To solve the problem of audio-video synchronous coding effectively,an embedding scheme is proposed.This scheme applies the quarter-pixel motion search during the motion estimation in H.264.At the transmitter terminal,according to the mapping rule between the binary audio bits and the search points,the audio bits are embedded into the video signal by modulating the best search point in the quarter-pixel motion estimation.Then the synchronous coding is applied to the hybrid signals.At the receiver terminal,the audio information bits are extracted from the video stream according to the embedding rule.Then the audio and video signals are reconstructed respectively.Experiment results show that the proposed scheme can achieve audio-video synchronous coding with low embedding cost and good performance in quality of video and audio signals.
Chromium-induced up conversion in GaP (1981)

In gallium phosphide, chromium doping allows the excitation of donor-acceptor type luminescence with light whose energy is smaller than the band gap and smaller than the emitted light energy. We discuss the behavior of that emission as a function of the excitation power together with electron paramagnetic resonance results. We conclude that the deep level involved is associated with Cr2+, located 1, 2 eV below the X conduction-band minimum. The up-conversion power efficiency of this sample is also reported.
