Reactivity of cationic molybdenum(II) complexes. Part 4. Isolation and crystal structure determination of cis-[Mo(CO)2(η-C5Me5)(PPh3)(N3)] and cis-[Mo(CO)2(η-C5Me5)(PPh3)(NCO)] (1989)

The complex [Mo(CO)3(η-C5Me5)(PPh3)]BF4(1) reacts with NaN3 in methanol solution to give a mixture of cis-[Mo(CO)2(η-C5Me5)(PPh3)(N3)](2) and cis-[Mo(CO)2(η-C5Me5)(PPh3)(NCO)](3), which were separated as pure products by column chromatography. Pure (3) was also obtained by an independent route, i.e. by treating a methanol solution of (1) with cyanate ion. The solid-state structures of complexes (2) and (3) were determined by single-crystal X-ray diffraction: they are isomorphous, space group P21/c(no. 14); for (2), a= 8.625(2), b= 18.655(9), c= 17.573(5)Å, β= 92.29(2)°, Z= 4,3 315 independent data [Io > 2.5σ(Io)] refined to R= 0.032, R′= 0.034; for (3), a= 8.641 (1), b= 18.547(3), c= 17.52(1)Å, β= 91.15(3)°,Z= 4, 2 045 independent data [Io > 2.5σ(Io)] refined to R= 0.044, R′= 0.046. Differences in the co-ordination geometry of the N3– and NCO– ligands are discussed.
On parallel processing of aggregate and scalar functions in object-relational DBMS (1998)

Nowadays parallel object-relational DBMS are envisioned as the next great wave, but there is still a lack of efficient implementation concepts for some parts of the proposed functionality. Thus one of the current goals for parallel object-relational DBMS is to move towards higher performance. In this paper we develop a framework that allows to process user-defined functions with data parallelism. We will describe the class of partitionable functions that can be processed parallelly. We will also propose an extension which allows to speed up the processing of another large class of functions by means of parallel sorting. Functions that can be processed by means of our techniques are often used in decision support queries on large data volumes, for example. Hence a parallel execution is indispensable.
Using very deep autoencoders for content-based image retrieval. (2011)

Abstract. We show how to learn many layers of features on color images and we use these features to initialize deep autoencoders. We then use the autoencoders to map images to short binary codes. Using semantic hashing [6], 28-bit codes can be used to retrieve images that are similar to a query image in a time that is independent of the size of the database. This extremely fast retrieval makes it possible to search using multiple di erent transformations of the query image. 256-bit binary codes allow much more accurate matching and can be used to prune the set of images found using the 28-bit codes. 1
Effect of trichothecenes on growth and intracellular pool size of Mycoplasma gallisepticum (1984)

The mycotoxin T-2 inhibited the growth of Mycoplasma gallisepticum. The growth inhibition was most pronounced with the hydrophobic derivatives T-2 acetate and very little with the hydrophilic T-2 tetraol. The toxin had no effect on the biosynthesis of either protein, DNA, RNA or complex lipids but markedly reduced the intracellular pool size of soluble low molecular mass precursors. It seems that T-2 acetate, by virtue of its hydrophobic nature, may accumulate within the lipid backbone affecting the permeability properties of the cell membrane.
Diamond film orientation by ion bombardment during deposition (1996)

The influence of ion bombardment during microwave plasma chemical vapor deposition (CVD) on diamond film orientation has been investigated. Two interesting findings were obtained: (1) The [001] axes of the grown diamond grains are always along the ion flow direction, perpendicular to the substrate and independent of the crystal orientation of the substrates and (2) for the crystallites which are homoepitaxially grown on the (001) diamond faces parallel to the substrate slight misorientations were found. These new findings confirm the role of ion impact in diamond CVD and can help us to understand the basic mechanism responsible for the crystal orientation in heteroepitaxial diamond films prepared using bias-enhanced nucleation.
Natural variation in acyl editing is a determinant of seed storage oil composition (2018)

Seeds exhibit wide variation in the fatty acid composition of their storage oil. However, the genetic basis of this variation is only partially understood. Here we have used a multi-parent advanced generation inter-cross (MAGIC) population to study the genetic control of fatty acid chain length in Arabidopsis thaliana seed oil. We mapped four quantitative trait loci (QTL) for the quantity of the major very long chain fatty acid species 11-eicosenoic acid (20:1), using multiple QTL modelling. Surprisingly, the main-effect QTL does not coincide with FATTY ACID ELONGASE 1 and a parallel genome wide association study suggested that LYSOPHOSPHATIDYLCHOLINE ACYLTRANSFERASE 2 (LPCAT2) is a candidate for this QTL. Regression analysis also suggested that LPCAT2 expression and 20:1 content in seeds of the 19 MAGIC founder accessions are related. LPCAT is a key component of the Lands cycle; an acyl editing pathway that enables acyl-exchange between the acyl-Coenzyme A and phosphatidylcholine precursor pools used for microsomal fatty acid elongation and desaturation, respectively. We Mendelianised the main-effect QTL using biparental chromosome segment substitution lines and carried out complementation tests to show that a single cis-acting polymorphism in the LPCAT2 promoter causes the variation in seed 20:1 content, by altering the LPCAT2 expression level and total LPCAT activity in developing siliques. Our work establishes that oilseed species exhibit natural variation in the enzymic capacity for acyl editing and this contributes to the genetic control of storage oil composition.
High-power single mode InGaAs/AlGaAs laser diodes at 910 nm (1990)

Single mode laser diodes have been fabricated from pseudomorphic InGaAs/AlGaAs quantum well epitaxial material operating up to 350 mW CW. The laser output is a single transverse and longitudinal mode to 180 mW, while the spectral output is centred near 910nm.
Summarization of Broadcast News Using Speaker Tracking (2009)

In this paper we demonstrate an automatic summarization system for broadcast news shows. The proposed technique does not require ASR transcripts or human reference summaries. The system exploits the role of anchor speaker in a news show by tracking his/her speech to construct indicative extractive summaries. Speaker tracking is done by autoassociative neural network model. Summaries are generated for desired compression ratio . The output summary is presented in the form of speech. The experiments were carried out on BBC news podcasts available online. The evaluation results show that summarization of structured speech documents like broadcast news shows can be performed with good accuracies comparable to text summarization.
REAL-TIME IMAGE BASED LIGHTING FOR OUTDOOR AUGMENTED REALITY UNDER DYNAMICALLY CHANGING ILLUMINATION CONDITIONS (2006)

Knowledge about illumination conditions in a real world scene has many applications, among them Augmented Reality which aims at placing virtual objects in the real world. An important factor for convincing augmentations is to use the illumination of the real world when rendering the virtual objects so they are shaded consistently and cast consistent shadows. The work presented in this paper aims at making a robust system capable of estimating the lighting of an outdoor scene, and apply the light changes to the virtual augmented objects that are placed within a real scene. The method uses an Irradiance Volume, modified to use an environment map of a given scene, to mimic the multiple lights reflected in a scene using Image Based Lighting, while normal Phong shading is used to mimic the sun shading. These are combined with a Shadow Volume method to ensure shadow interaction with the surrounding environment. For every frame an Illumination Estimation approximates local illumination light parameters used in the rendering of the augmented objects. The light parameters are furthermore used to, at runtime, create new environment maps, to update the irradiance volume. The result is a rendering pipeline capable of handling dynamic light changes, and applies them to augmented objects within a given scene, enabling realistic augmentations under changing illumination conditions.
Comparative immunohistochemical study of deep infiltrating endometriosis, lymph node endometriosis and atypical ovarian endometriosis including description of a perineural invasion (2020)

The immunophenotype of the cases in groups 1 and 2 and in the control group was virtually identical in the proliferative phase - strong nuclear ER and PR expression in more than 90% of endometrial glandular and stromal cells. In the early and mid secretory phase, ER expression only slightly decreased (80%) in endometrial glandular cells in group 2 and the control group, whereas in the late secretory phase, significant decrease of ER expression only in the control group was observed (15-50%; P<0.001). In group 2 and the control group, significant decrease of PR expression only in endometrial glandular cells was observed in the mid and late secretory phase (less than 15%; P<0.001). Differences in receptor content were found only in isolated cases in group 2. In group 1, no secretory changes were found. In all three groups, sporadic and weak nuclear p53 expression in less than 3% in both endometrial glandular and stromal cells was detected (regardless of the phase of the menstrual cycle). In atypical ovarian endometriosis, higher and strong p53 expression (on average 26%) and decrease in ER (on average 56%) and PR (less than 1%) expression was observed; compared to the control group and groups 1 and 2, the differences for all 3 markers were highly significant (P<0.001). In all groups, the proliferation index (Ki-67) reached the highest values in the proliferation phase and decreased during the cycle. However, in endometriotic tissue, it was widely variable in the individual phases of the cycle. Perineural spread of endometriosis with significant neural hypertrophy, hyperplasia and involvement of the ganglia of the autonomic nervous system was detected in 5 cases (12.5%). Conlusion. From a histological and immunohistochemical point of view, deep infiltrating endometriosis and lymph node endometriosis appear to represent the same entity. For the first time, a simple immunohistochemical panel with antibodies against ER, PR and p53 useful in diagnosing atypical endometriosis has been described. The marked endometriosis-associated neural changes (endometriotic neuropathy) could be one of the causes of impaired function of the affected organs after debulking surgery with macroscopic negative resection margins as well as pain symptomatology in macroscopic inapparent endometriotic lesions.

Positron emission tomography in the management of neuroendocrine tumors. (2003)

Neuroendocrine tumors (NET´s) are often characterized by overproduction of peptide hormones. In spite of pronounced clinical symptoms, the tumor lesions can be small and difficult to detect. The general aim of this thesis was to investigate, in vitro and in vivo, some of the potential monoamine pathways present in NET´s, using radiolabeled tracers for positron emission tomography (PET), with the intention to explore the value of PET-imaging in the management of NET´s. We used the 11C-labeled serotonin precursor 5-hydroxy tryptophan (HTP) as the tracer for imaging of NET´s. More than 95% of the subjects displayed a high tracer uptake on PET and tumor detection rate with PET was higher in &amp;gt;50% of the patients compared both to computed tomography (CT) and somatostatin receptor scintigraphy (SRS). The primary tumor was imaged by PET in 84% (16/19), compared to 47% and 42% for SRS and CT, respectively. Tumor visibility was better with PET due to a higher tumor-to-background ratio and a better spatial resolution. There was a strong correlation (r = .907) between changes in urinary-5-hydroxy indole acetic acid and changes in transport rate of 11C-5-HTP during treatment, indicating the use of PET in treatment monitoring of NET´s. Pretreatment with carbidopa decreased the urinary radioactivity concentration four-fold and significantly (p&amp;lt;0.001) increased the tumor tracer uptake. This greatly improved image interpretation and tumor lesion detection. A screening for expression of monoamine pathways in NET´s revealed a high in vitro binding of the monoamineoxidase-A ligand harmine to tumor sections. PET examinations with 11C-harmine could visualize tumors in all patients, including non-functioning endocrine pancreatic tumors (EPT´s). Finally, the in vitro turnover and in vivo distribution of the amino acids glutamate, glutamine and aspartate was investigated. Limited uptake in vivo indicates the lack of utility for these substances as PET-tracers for imaging and characterization of NET´s.
Upper extremity pain in the postrehabilitation spinal cord injured patient. (1992)

The purpose of this study was to determine the prevalence of upper extremity (UE) pain in outpatients with chronic spinal cord injury (SCI). A total of 239 SCI outpatients (136 with quadriplegia and 103 with paraplegia) were interviewed for the presence of UE pain at the shoulder, elbow, wrist, and hand. The average age of the subjects at the time of interview was 37.4 years, and the average time since onset was 12.1 years. Subjects who reported pain were referred to SCI clinics to determine the etiology. Fifty-five percent of the patients with quadriplegia reported UE pain, most commonly at the shoulder. Prevalence of reported pain was highest for subjects in the first five years postinjury. Sixty-four percent of patients with paraplegia reported UE pain. Complaints related to carpal tunnel syndrome were the most common, followed by those related to shoulder pain. This study documents the prevalence and nature of UE pain in chronic SCI patients and emphasizes the need for further research to develop strategies for prevention and treatment of pain syndromes.

Results of targeted next-generation sequencing in children with cystic kidney diseases often change the clinical diagnosis (2020)

Cystic kidney diseases are a very heterogeneous group of chronic kidney diseases. The diagnosis is usually based on clinical and ultrasound characteristics and the final diagnosis is often difficult to be made. Next-generation sequencing (NGS) may help the clinicians to find the correct final diagnosis. The aim of our study was to test the diagnostic yield of NGS and its ability to improve the diagnosis precision in a heterogeneous group of children with cystic kidney diseases. Next-generation sequencing of genes responsible for the formation of cystic kidneys was performed in 31 unrelated patients with various clinically diagnosed cystic kidney diseases gathered at the Department of Pediatrics of Motol University Hospital in Prague between 2013 and 2018. The underlying pathogenic variants were detected in 71% of patients (n = 22), no or only one (in case of autosomal recessive inheritance) pathogenic variant was found in 29% of patients (n = 9). The result of NGS correlated with the clinical diagnosis made before the NGS in 55% of patients (n = 17), in the remaining 14 children (45%) the result of NGS revealed another type of cystic kidney disease that was suspected clinically before or did not find causal mutation in suspected genes. The most common unexpected findings were variants in nephronophthisis (NPHP) genes in children with clinically suspected autosomal recessive polycystic kidney disease (ARPKD, n = 4). Overall, 24 pathogenic or probably pathogenic variants were detected in the PKHD1 gene, 8 variants in the TMEM67 gene, 4 variants in the PKD1 gene, 2 variants in the HNF1B gene and 2 variants in BBS1 and NPHP1 genes, respectively. NGS is a valuable tool in the diagnostics of various forms of cystic kidney diseases. Its results changed the clinically based diagnoses in 16% (n = 5) of the children.
Analysis of Data Remanence in a 90nm FPGA (2007)

FPGAs are increasingly used in military applications, the security of a design when the part is powered off is an important property that needs to be analyzed. In this paper, we study data remanence in modern FPGAs using a custom 90nm FPGA designed for this test. The effects of temperatures, architecture, memory topology, and power off methods are analyzed. We find that different memory cells in the FPGA architecture have different remanence properties depending on their circuit design, data content, leakage and supply noise. To our knowledge, this is the first study of data remanence in FPGAs and in deep-submicron ICs.
Therapeutic blockade of arteries using compressed Ivalon. (1980)

A new technique for embolization with compressed Ivalon plugs is described. Fourteen arteries--six renal, three splenic, two pulmonary, one left gastric, and two abdominal aortas--were occluded in six dogs. In one case of renal artery embolization, three plugs were used, and in one case of abdominal aorta embolization, two were needed for total occlusion. In all other cases only one plug was used. Total occlusion was angiographically demonstrated up to five months following embolization in all but one case. In this case, recanalization was thought to have occurred because of overcompression of the Ivalon plug.
Different signaling pathways for CD18-mediated adhesion and Fc-mediated phagocytosis. Response of neutrophils to LPS. (1994)

The regulation of CD11b/CD18 adhesive and phagocytic functions on human polymorphonuclear leukocytes (PMN) in response to LPS was examined. Adhesion of PMN to surfaces coated with LPS had little or no effect on the cells, but pretreating the LPS-coated surfaces with either diluted serum or LPS-binding protein strongly enhanced their ability to bind C3bi-coated E (EC3bi), a ligand for CD11b/CD18. LPS-binding protein is known to enable responses of cells to LPS by facilitating binding of LPS to CD14. Consistent with this, we found that preformed complexes of LPS with soluble rCD14 stimulated binding of ligand by CD11b/CD18 in a concentration-dependent manner. Known agonists that stimulate CD11b/CD18 binding activity on PMN all cause simultaneous enhancement of Fc-mediated phagocytosis. However, LPS presented in complex with either serum proteins or CD14 failed to stimulate the ingestion of ElgG by PMN. The number of FcRs and their ability to bind ligand were not affected by treatment with LPS, nor were they compromised in their ability to respond to other agonists. These results suggest that LPS generates intracellular signals that alter the ability of CD11b/CD18 to bind ligand, but this alteration is not sufficient to promote phagocytosis of IgG-coated particle. This conclusion was confirmed by showing that PMN treated with LPS and serum produced a lipid with the properties of integrin-modulating factor 1: acetone extracts of these cells stimulated CD11b/CD18 adhesive capacity on PMN. However, the lipid did not enhance Fc-mediated phagocytosis. These studies suggest that CD14 affects CD11b/CD18 function by inducing the synthesis of a lipid such as IMF-1, and that this lipid affects only the binding activity, not the phagocytosis-promoting capacity of CD11b/CD18.
Linear magnetic susceptibility of anisotropic superconductors of cuboidal shape (2023)

A simplified model of anisotropic magnetic susceptibility in the Meissner–London vortex-free state of cuboidal superconducting samples is presented. Using this model, precision measurements of the magnetic response in three perpendicular directions of a magnetic field with respect to primary crystal axes can be used to extract the components of the London penetration depth, thus enabling the evaluation of the general superfluid density tensor, which is needed in the analysis of the superconducting gap structure.
Differential effect of Calcium and Magnesium on Mechanical Properties of Pea Stem Cell Walls (1981)

Replacement of calcium ion with magnesium ion in the cell wall of the pea epicotyl makes the wall more extensible. A possible role of this differential effect of Ca2+ and Mg2− in regulating cell elongation in pea epicotyl is discussed. The ratio of the content of calcium ion to that of magnesium ion (Ca2+/Mg2+) in the walls decreased markedly in the order of the first > the second > the third internodes of the pea epicotyl. The capacity of the walls for cation exchange increased in the same order, whereas the calcium-magnesium ion exchange selectivity of the walls was virtually constant. Our results indicate that the changes in the Ca2+/Mg2+ ratio among the internodes is not attributable to the ion exchange properties of the walk per se, but is due to other physiological conditions which regulate the activities of free calcium and magnesium ions in the environment with which the walls are in equilibrium.
Design, Simulation, and Fabrication of a Novel Vibration-Based Magnetic Energy Harvesting Device (2007)

In this paper, we have described a vibration-based magnetic energy harvesting device (VMEHD). The VMEHD converts mechanical energy from the environment to electrical energy by using the piezoelectric effect and frequency rectification. Magnetic arrays are used to rectify the incoming frequency to a higher frequency using non-contact mechanisms. The finite element analysis is used to simulate the VMEHD. Testing results show that the output voltage is between 8 volts to 12 volts with input frequency of 10 Hz and a rectified frequency of 22 Hz. This provides large power densities to be obtained in a mechanical energy harvesting device.
Agricultural Water Conservation- A Global Perspective (2000)

Summary Water for agriculture generally is adequate in humid regions, but water conservation often is needed in subhumid and semiarid regions for good crop production, even with irrigation because of limited supplies. Increasingly, urban, industrial, environmental, and recreational users compete for agricultural water supplies. Although temporally and spatially variable, annual total supplies are relatively constant. The increasing competition, therefore, makes it imperative that agriculture does its share to conserve water to achieve greater production for an ever-increasing populace. In this report, we discuss basic principles of and some practices for achieving agricultural water conservation, both under dryland (rainfed) and irrigated conditions.
