Building Calibration Functions for Angular Position of the Trihedron of Accelerometers (2021)

Статья посвящена построению калибровочных функций углового положения конструктивно выполненных автономных блоков из трех ортогонально расположенных акселерометров в рамках технологической процедуры их статической калибровки для повышения точности определения проекций силы тяжести на координаты связанной с объектами пространственно-ортогональной системы координат. Для этого использованы два варианта угловых преобразований осей координат: в углах Эйлера и в самолетных углах. При проведении контроля и диагностики точности показаний акселерометров в триэдре рекомендуется проводить измерения вектора силы тяжести, выполняя полные обороты по какому-либо одному из углов.Математическая основа для построения функций системной калибровки триэдра акселерометров описана в рамках процедур перепроецирования измерительных сигналов на «правильные» ортогональные оси. Приведены получающиеся линейные и нелинейные калибровочные функции. Рассмотрены варианты улучшения обусловленности вычислительных алгоритмов для идентификации линейных и нелинейных калибровочных функций углового положения триэдра акселерометров.Приведены вычислительно облегченные методики, предназначенные для серийной калибровки триэдров акселерометров. В них использовано разложение показаний акселерометров вдоль осей «искаженной» системы координат на оси «правильной» ортогональной системы координат.В качестве примера приведено сравнение результатов линейной и нелинейной калибровки блока из трех акселерометров АК-15 на стенде. Показано, что для выбранных прецизионных акселерометров вполне достаточно использовать линейную методику калибровки.
Dynamic Behavior of Heart Rate in Ischemic Stroke (1999)

Hemispheric and medullary brain stem infarctions seem to damage the cardiovascular autonomic regulatory system and appear as abnormalities in the magnitude of HR variability. These abnormalities can be more easily detected with the use of analysis methods of HR variability, which are based on moment statistics, than by methods based on nonlinear dynamics. Abnormal HR variability may be involved in prognostically unfavorable cardiac complications and other known manifestations of autonomic failure associated with stroke.
Ig DH Gene Segment Transcription and Rearrangement Before Surface Expression of the Pan-B–Cell Marker CD19 in Normal Human Bone Marrow (1997)

The onset of IgH transcription and rearrangement is a defining characteristic of the progenitor population in which B-lineage commitment occurs. These features were used to better define the earliest stage of B-cell commitment in humans and to determine if these stages differ as a function of human ontogeny. Fetal and adult bone marrow mononuclear cells were sorted into B-lineage subpopulations on the basis of surface expression of the stem cell marker CD34, the pan-B-cell marker CD19, and IgM and analyzed for transcription and rearrangement of the IgH locus. The locus was found to be transcriptionally active before surface expression of CD19, as indicated by the presence of germline I mu, C mu, and D(H)Q52 transcripts in the CD34+ CD19- subpopulation. Transcripts from IgH alleles that had undergone DJC mu rearrangements were also detected in the CD34+ CD19- subpopulation. Within this subpopulation, low levels of DXP-containing DJC mu transcripts were detected in both fetal and adult cells. Although D(H)Q52 DJC mu transcripts were abundant in fetal CD34+ CD19- cells, they were not detected in cells of the same phenotype derived from adult bone marrow. In both fetus and adult, V(H)3-and V(H)6-containing VDJC mu transcripts were detected only in the CD19+ subpopulations. These data indicate that transcription of D(H)Q52-J(H) and DXP-J(H) rearrangements differs during fetal and adult B lymphopoiesis. Moreover, in both fetus and adult, transcription of unrearranged components of the IgH locus and DJ rearrangements can proceed before the surface expression of CD19.

Experimental and computer simulation studies of the “baffled target” reactive sputtering process (2003)

Reactive sputtering is a technique widely employed for deposition of compound materials. One drawback encountered with this technique is that the target normally ends up in poisoned mode at reactive gas flow levels necessary for depositing a stoichiometric film, causing a severe drop of the deposition rate. To decrease the target poisoning a reactive sputter deposition technique based on the so-called baffled target has been suggested. In this configuration a target is confined in a box having a front aperture allowing sputtered material to be deposited through the aperture onto the substrate located in the main chamber. The purpose of this box is to separate the reactive gas in the chamber from the target thereby decreasing the target poisoning. We have carried out computer simulations as well as experimental studies on the baffled target technique. The computer simulations serve to explain the reactive gas gettering and the corresponding process behavior in the box and in the chamber, respectively. The calculations also assist in finding optimum operating conditions for this novel technique. It was found that it is possible to find operating conditions where compound film formation is achieved with the target in high rate metal mode at a supply level of reactive gas far below the level required to reach the hysteresis region. This is a unique property of the baffled target technique that may not be obtained in traditional reactive sputtering system configurations.
Overcoming Hybrid Lethality Induced by Chromosomal Instability in an Interspecific Hybrid of Genus Nicotiana (2021)

Abstract Hybrid lethality is a type of reproductive isolation in which hybrids die before maturation, due to the interaction between the two causative genes derived from each of the hybrid parents. The interspecific hybrid of Nicotiana suaveolens x Nicotiana tabacum is a model plant for studies of hybrid lethality. In this cross, most hybrid seedlings die, but rare individuals grow normally and mature. Separately, a technique for producing mature hybrids by artificial culture has been developed. However, the mechanism by which hybrids overcome lethality, either spontaneously or by artificial culture, remains unclear. In the present study, we found that some hybrids that overcome lethality, either spontaneously or by artificial culture, lack the distal part of the Q chromosome, a region that includes the gene responsible for lethality. Quantitative polymerase chain reaction results suggested that the distal deletion of the Q chromosome, detected in some hybrid seedlings that overcome lethality, is caused by reciprocal translocations between homoeologous chromosomes. These results indicated that the chromosomal instability during meiosis of the amphidiploid N . tabacum and during artificial culturing of hybrid seedlings is involved in overcoming hybrid lethality in interspecific hybrids of the genus Nicotiana .
Development of an Autonomous Endoscopically Implantable Submucosal Microdevice Capable of Neurostimulation in the Gastrointestinal Tract (2017)

Gastric dysmotility can be a sign of common diseases such as longstanding diabetes mellitus. It is known that the application of high-frequency low-energetic stimulation can help to effectively moderate and alleviate the symptoms of gastric dysmotility. The goal of our research was the development of a miniature, endoscopically implantable device to a submucosal pocket. The implantable device is a fully customized electronics package which was specifically designed for the purpose of experiments in the submucosa. The device was endoscopically inserted into the submucosal pocket of a pig stomach and partially severed pig side in order to adequately simulate a live animal model. The experiment confirmed that the designed device can be implanted into the submucosa and is capable of the measurement of sensor data and the transmission of this data wirelessly in real time to a computer outside of the body. After proving that the device can be implanted submucosally and transmit data, further experiments can now be performed, primarily with an electrogastrography (EGG) instrument and implantable device with tissue stimulation capability.
Toward Spoken Human–Computer Tutorial Dialogues (2010)

Oral discourse is the primary form of human–human communication, hence, computer interfaces that communicate via unstructured spoken dialogues will presumably provide a more efficient, meaningful, and naturalistic interaction experience. Within the context of learning environments, there are theoretical positions supporting a speech facilitation hypothesis that predicts that spoken tutorial dialogues will increase learning more than typed dialogues. We evaluated this hypothesis in an experiment where 24 participants learned computer literacy via a spoken and a typed conversation with AutoTutor, an intelligent tutoring system with conversational dialogues. The results indicated that (a) enhanced content coverage was achieved in the spoken condition; (b) learning gains for both modalities were on par and greater than a no-instruction control; (c) although speech recognition errors were unrelated to learning gains, they were linked to participants' evaluations of the tutor; (d) participants adjusted their conversational styles when speaking compared to typing; (e) semantic and statistical natural language understanding approaches to comprehending learners' responses were more resilient to speech recognition errors than syntactic and symbolic-based approaches; and (f) simulated speech recognition errors had differential impacts on the fidelity of different semantic algorithms. We discuss the impact of our findings on the speech facilitation hypothesis and on human–computer interfaces that support spoken dialogues.
Capillary Endothelial Cell Multiplication in Adipose Tissue Pads on the Thyroid during the Feeding of Thiouracil (1983)

It has been reported that blood capillaries in adipose tissue pads on the upper and lower poles of the thyroid gland enlarge when Fischer rats are fed thiouracil (TU) in a low iodine diet. To test whether the enlargement is accompanied by proliferation of the endothelial cells, [3H]thymidine was injected into rats fed the TU-containing diet, and labeling of the endothelial cells was studied by autoradiography. Nuclear labeling of the capillary endothelial cells was observed in the mixed brown and white adipose tissue (BAT and WAT, respectively) pads on the thyroid. After a single pulse of [3H]thymidine, 10% of the nuclei were labeled at 10 days (the peak labeling), and labeling decreased thereafter. To test whether the adipose tissue was stimulated because of the poor nutritional quality of the low iodine diet, Purina Laboratory Chow (a nutritionally adequate diet) was tested and produced the same result. To test whether TU had a direct effect, 5 micrograms T4/100 g BW were given daily; there was then no response to the TU, suggesting that the effect was due to an elevated circulating concentration of TSH. The effect was generally restricted to the adipose tissue pads on the thyroid. There was no response in interscapular BAT, epididymal WAT, or sc WAT. However, there was a response in small clusters of adipocytes embedded in inguinal sc WAT. The results are consistent with the idea that the effects are directly or indirectly due to elevated circulating TSH levels.
FROM LOCAL POLYNOMIAL APPROXIMATION TO POINTWISE SHAPE-ADAPTIVE TRANSFORMS: AN EVOLUTIONARY NONPARAMETRIC REGRESSION PERSPECTIVE (2011)

In this paper we review and discuss some of the theoretical and practical aspects, the problems, and the considerations that pushed our research from the one-dimensional LPA-ICI (local polynomial approximation- interesection of conÞdence intervals) algorithm [27] to the development of powerful transform-based methods for anisotropic image
Crystal aggregates with induced morphologies grown by silica gel technique (1981)

This paper deals with the genetic mechanism of the morphologies present in BaCO₃and CaCO₃ grown by silica gel technique at basic pH. Our results show that a siliceous matrix acting as support induces the whole morphology of the aggregate. Earlier, the existence of such a membrane was inferred from physico-chemical conditions required by the growth technique. In the present research, the experimental proof of its existence is given, as well as the logical arguments required.
Alternating high-risk human papillomavirus infection (2006)

In light of the current study findings, the authors believe it is worth considering the inclusion of women age 40 years and older who have negative cytology for HPV testing as part of the Dutch national screening program.
Enhancement in the Safety of Immune Globulins Prepared from High-Risk Plasma (1993)

Hyperimmune gamma-globulins have proven efficacious in the prevention and treatment of viral infections, including those caused by hepatitis A and B viruses, cytomegalovirus, parvovirus. Interest in the prevention and/or treatment of infections caused by human immunodeficiency virus (HIV) has led to clinical trials with anti-HIV immune plasma and purified immune globulin prepared from donors who are actively infected with HIV. The handling and fractionation of this or other infectious plasma requires the construction and operation of virus containment facilities designed to protect fractionation employees and the immediate environment. This requirement would be reduced substantially by applying virucidal procedures prior to or during plasma pooling. We have shown that heating plasma at 56 degrees C for 1 h followed by treatment with 1% tri(n-butyl) phosphate (TNBP) and 1% Triton X-100 for 4 h at 30 degrees C resulted in the inactivation of > or = 10(12.1) tissue culture infectious doses (TCID50) of HIV. With this treatment, the recovery of IgG was 87 +/- 3%. Fractionation of treated plasma by cold ethanol precipitation proceeded normally, and overall recovery, purity, and potency against selected viral markers were unaffected. The additional treatment of plasma with 15 g/l Aerosil for 4 h at 45 degrees C removed 10(4.5) TCID50 of HIV but resulted in substantial IgG losses both prior to and following fractionation. We conclude that potentially infectious plasma can be treated at 56 degrees C for 1 h and by TNBP/Triton X-100 at 30 degrees C for 4 h prior to fractionation. These steps appear sufficient to assure safety and to permit routine fractionation of plasma.(ABSTRACT TRUNCATED AT 250 WORDS)
Neurogenic Hypertension (1985)

Although an extensive literature exists concerning essential arterial hypertension, the primary etiology has been unclear. Arterial compression of the left lateral medulla oblongata by looping arteries of the base of the brain was seen incidently in 51 of 53 hypertensive patients who underwent left retromastoid craniectomy and microvascular decompression for unrelated cranial nerve dysfunctions. Such compression was not noted in normotensive patients. Treatment by vascular decompression of the medulla was performed in 42 of the 53 patients. Relief in the hypertension was seen in 32 of the patients and improvement in four. Arteriosclerosis and arterial ectasia contribute to arterial elongation and looping. If pulsatile compression of the left lateral medulla occurs, hypertension may develop as a consequence of an imbalance in the neural control systems that normally regulate blood pressure. The hypertension may further contribute to arterial elongation, providing a vicious circle of pathophysiologic changes.
Partial Incorporation of Nonlinear Resistive Field Grading Materials: A Strategy for Enhanced Field Reduction and Safety (2022)

In this study, we fabricate, characterize, and apply nonlinear resistive field grading (NLRFG) materials in vacuum recloser, cable joint, and outdoor cable termination models. The NLRFG materials are fabricated by dispersing various sizes and loadings of zinc oxide (ZnO) nanofillers in polymer matrices including epoxy resin and silicone rubber. The nonlinearly varying resistivity of these materials is characterized by measuring <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${I}$ </tex-math></inline-formula> – <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${V}$ </tex-math></inline-formula> curves. The <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${I}$ </tex-math></inline-formula> – <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">${V}$ </tex-math></inline-formula> characteristics of the NLRFG materials are modeled and incorporated into a finite element analysis (FEA) platform. The electric field reducing the performance of the fabricated NLRFG composites is analyzed in FEA based on the actual designs of vacuum recloser, cable joint, and outdoor cable termination. Three different case studies are reported: 1) where regular epoxy or regular silicone rubber is used; 2) where NLRFG materials are used; and 3) where NLRFG materials are partially incorporated. The results suggest that 37%, 27%, and 29% reductions in the local maximum electric field are achieved when NLRFG materials are used in the vacuum recloser, cable joint, and outdoor cable termination, respectively. Power loss caused by leakage current in these models is also analyzed. The findings imply that the partial implementation of NLRFG materials not only could be more effective in terms of electric stress reduction but more safe than the full incorporation of them as it prohibits the formation of conductive paths across high-voltage and ground during overvoltage transients that can be caused by lightning strikes.
Large Nasal Tip Teratoma (1995)

Congenital teratoma rarely occurs in the craniofacial region. We present an infant with a nasal tip teratoma that was documented by ultrasonographic examination. The tumor was excised at 1 day of life, and the splayed upper and lower lateral cartilages were apposed primarily. The remaining redundant skin was excised in a second stage. To our knowledge, this is the first reported case of a nasal tip teratoma.
Third generation oral contraceptives and risk of venous thromboembolic disorders: an international case-control study (1996)

Risk of venous thromboembolism was slightly increased in users of third generation oral contraceptives compared with users of second generation products.
Identification of the pore forming element of Semliki Forest virus spikes (1995)

Pore formation at mildly acidic pH by SFV spike proteins was investigated using isolated and modified virions. Modification of the virions was performed by limited proteolysis in presence of octylglucoside and resulted in the formation of E1 particles and spikeless particles, respectively. Pore formation was detected by measuring the influx of propidium iodide into the viral particles. The results obtained clearly showed that the presence of E1 alone is sufficient to promote pore formation at mildly acidic pH. Thus E1 represents the pore forming element of the viral spike proteins.
Antennas for RFID tags (2005)

This communication covers the design and optimization of antennas for RFID tags at UHF and microwave frequencies. Such design will focus on the specific characteristics of RFID applications such as back-scattering mode, variability of substrates and low cost constraints. The introduction includes a short history of RFID development. The second part will address the main characteristics of RFID antennas. The third part introduces the material characterization. Current developments of RFID antennas that meet the objectives of low-cost and size reduction are presented in part four. Design of antennas on plastic substrate using conductive inks will be shown as an example of low-cost approach. Advanced design techniques for size reduction, such as fractal techniques will be introduced and some design examples will be discussed. The fifth part concerns antenna modeling from the system point of view and examples of system simulation of an RFID communication will be shown.
Do patients after off-pump coronary artery bypass grafting need the intensive care unit? A prospective audit of 85 patients (2007)

With limited resources, cardiac surgery is frequently cancelled due to lack of ICU beds. Immediate postoperative extubation (UFT) is performed in our hospital setting. The aim of the present study is to report patients undergoing off-pump aortocoronary bypass grafting (OPCABG) with immediate extubation and no ICU stay. Eighty-five patients undergoing OPCABG were included. UFT analgesia consisted of high thoracic epidural analgesia (n=65), or PCA morphine (n=20). Discharge criteria from PACU to cardiac ward were: alert, cooperative patient, respiratory rate <25/min, PaO(2)>80 mmHg and PaCO(2)<45 mmHg, temperature >36 degrees C, hemodynamic stability, no bleeding, no ischemia, and sufficient analgesia. More males (71/14) were included. Mean age was 63.4 years, NYHA class III, ejection fraction 59.4. Three grafts were performed in 119 min. Patients were extubated 12+/-2 min after closure. After 428 min in PACU, four patients did not meet ward criteria; three bradycardia requiring pacing, one elevated CK-MB. Two patients returned to the ICU, one for hypertension, and one for hypovolemia. Cardiac complications were: atrial fibrillation (29%), MI=2, bradycardia=3. During the same period, 304 OR-extubated patients spent 21+/-6 h in the ICU. The cost from leaving the OR until the patient reached the cardiac ward was 1265$ for ICU bypass patients vs. 6405$ for ICU patients, the difference representing 5140$ per patient. ICU bypass after OPCABG is safe. By avoiding ICU, this protocol reduces costs, improves resource utilization and may reduce OR cancellation due to ICU bed shortages.
Improved step edges on LaAlO3 substrates by using amorphous carbon etch masks (1994)

We report a technique for the fabrication of sharp and straight step edges on LaAlO3 (LAO) substrates by ion milling. An electron beam lithography defined amorphous carbon film was used as an etch mask. It had very low ion milling rate and was easily prepared and removed. Atomic force microscopy was used to determine the step profile. YBa2Cu3O7 step edge junctions fabricated at the LAO steps show promising results. An IcRn product of 1 mV was obtained at 30 K. A Fraunhofer-like magnetic field dependence of Ic was obtained up to ±2 Φ0. One weak link or possibly identical weak links in series for these step edge junctions were observed from the current-voltage (I-V) curves as well as from the magnetic field dependence of the I-V curves.
Functional and oncological outcomes of open, laparoscopic and robot‐assisted partial nephrectomy: a multicentre comparative matched‐pair analyses with a median of 5 years’ follow‐up (2018)

In the present study, RAPN, LPN and OPN had similar local recurrence, distant metastasis and cancer-related death rates at a 5-year median follow-up. In terms of functional outcomes, RAPN was associated with a lower incidence of CKD upstaging compared with OPN and LPN.
