Abnormally high work hardening ability and excellent comprehensive properties of copper alloys due to multiple twins and precipitates (2023)

In the present work, the Cu-1.35Ni-1Co-0.55Si alloy with multiple twins and ultra-low interfacial mismatch precipitates was obtained by liquid nitrogen dynamic plastic deformation (DPD) and aging treatment. It has abnormally high work hardening ability, which is more than twice that of the previous DPD treatment without aging. In addition, it has excellent comprehensive properties, and its strength, electrical conductivity, and elongation are 816.4 MPa, 40.2% IACS and 11.3% respectively. The fine multiple twins do not coarsen significantly during peak aging, and the dispersed nano precipitates (∼3 nm) further enhance the strength of the Cu-Ni-Co-Si alloy. In addition, the low interfacial mismatch strain between the precipitates and the matrix also ensures adequate elongation. The Cu-Ni-Co-Si alloy has high strength, electrical conductivity, and ductility under the simultaneous action of various mechanisms (grain boundary strengthening, precipitation strengthening, dislocation strengthening and stacking faults). This strategy paves a new avenue for developing precipitation-strengthened alloys with excellent comprehensive properties.
Altered balance of main vasopressor and vasodepressor systems in rats with genetic hypertension and hypertriglyceridaemia (2002)

The precise role of nitric oxide (NO) in hypertension is still not fully understood, although this vasodilator system represents the main counterbalance of major pressor systems. The aim of our study was to determine the contributions of superoxide anions, the renin-angiotensin system (RAS), the sympathetic nervous system (SNS) and NO to the maintenance of blood pressure (BP) in Prague hereditary hypertriglyceridaemic (HTG) rats with genetic hypertension. Conscious chronically cannulated rats were subjected to the consecutive blockade of the RAS (losartan, 10 mg/kg), the SNS (pentolinium, 5 mg/kg) and NO synthase [N(omega)-nitro-L-arginine (L-NAME), 30 mg/kg]. Some additional rats were pretreated with tempol (a membrane-permeable mimetic of superoxide dismutase). A subsequent genetic study in HTG x Lewis F(2) hybrid rats (n=284) was designed to reveal potential associations of particular BP components with baseline BP. The progenitor study indicated that BP elevation was more pronounced in male than female HTG rats (as compared with normotensive Lewis controls). Higher BP in HTG rats was due to the increased residual BP (measured after combined RAS and SNS blockade) and the augmentation of BP responses to tempol or losartan. In contrast, BP responses to pentolinium or l-NAME were similar in all experimental groups. It should, however, be noted that the baseline BP of progenitor animals was correlated positively with both residual BP and the magnitude of the BP response to pentolinium, but not with BP response to L-NAME. Similarly, the baseline BP of F(2) hybrid rats was positively associated with residual BP, the BP response to pentolinium and the relative SNS contribution to BP maintenance [expressed as a percentage of baseline mean arterial pressure (MAP) values], as well as with the ratio of BP changes elicited by ganglion blockade and NO synthase inhibition (Delta MAP(pentolinium)/Delta MAP(L-NAME) ratio), reflecting the balance of main vasopressor and vasodepressor systems. Thus our studies, performed in progenitor and F(2) hybrid rats, revealed that changes in BP induced by L-NAME do not keep pace with the progressive augmentation of pentolinium-induced changes in BP occurring over a wide range of increasing BP. The altered balance between enhanced SNS-dependent vasoconstriction and unchanged NO-dependent vasodilation ('relative NO deficiency' in rats with high BP) might result in BP elevation in this form of genetic hypertension.
Radiofrequency lumbar facet denervation: analysis of prognostic factors (1994)

Percutaneous radiofrequency lumbar facet denervation has been in use as a treatment for intractable, mechanical low back pain for over 2 decades. A number of case series have been reported with high rates of success in selected patients; however, there has been limited objective outcome assessment, long-term follow-up, and analysis of prognostic factors. We have reviewed our experience with diagnostic lumbar facet blocks and percutaneous radiofrequency denervation at a mean follow-up interval of 3.2 years. Long-term outcome has been assessed by disinterested third party interview. Of 82 patients selected for these procedures, 56 had undergone prior low back surgery. Following diagnostic medial branch posterior primary ramus blocks, 42 reported at least 50% relief of pain and proceeded to radiofrequency denervation. Forty-five percent of patients undergoing denervation reported at least 50% relief of pain at long-term follow-up. Among the 40 patients who only underwent temporary blocks, 13% reported relief (i.e., spontaneous improvement or placebo effect) by at least 50% at long-term follow-up). By multivariate statistical analysis, patients undergoing bilateral blocks for bilateral or axial symptoms were significantly more likely to achieve temporary relief, and to proceed to permanent denervation. There was no difference, however, between the long-term results of bilateral denervation for bilateral or axial pain and those of unilateral denervation for unilateral pain. There was no significant difference in the rate of response between the 56 patients who had undergone prior lumbosacral spine surgery and the 26 who had not. There were no complications from the procedure.(ABSTRACT TRUNCATED AT 250 WORDS)
Screening for Hearing Loss in Adolescents (1997)

Three-hundred-forty-two adolescents between the ages of 10–20 years were administered an auditory screening protocol consisting of a: (a) noise history questionnaire, (b) otoscopic inspection, (c) tympanometry, and (d) pure-tone screening at 25 dB HL at 1000, 2000, 4000, and 6000 Hz. Results of this screening protocol suggest a high level of admitted noise exposure in the adolescent population. Overall failure rate was 25%. Pure-tone failure rate was 7% for the frequencies of 1000, 2000, and 4000 Hz, increasing to 17% when 6000 Hz was added. Significant correlations were found between firearm use and hearing loss at 6000 Hz. Recommendations for screening the adolescent population are made, and suggestions for educational intervention on the effects of firearm usage are provided.
Imaging of two-dimensional nanoplasmonic structures by nanoscopy with contact microlenses and various microscope objectives (2016)

The use of contact microlenses attracted a great deal of attention recently because in the case of imaging nanoplasmonic structures it showed the resolution values exceeding the classical diffraction limit. The mechanisms that allow for this type of imaging are presently still debated in the literature; these range from photonic nanojets, plasmon-polaritons, localized surface plasmon resonances and coherent modal excitation in metallic objects, as well as optical resonances in microsphereical lenses. The system of interest is metallic nanoobjects coupled to a dielectric microsphere and is considered as a directional antenna. In this work, we performed preliminary studies of how the resolution of this method depends on the numerical aperture of the microscope objective. We used 2D periodic nanoplasmonic arrays. Based on assumption of incoherent imaging, we demonstrated that the resolution is reduced from ~λ/7 to ~λ/4 for a reduction of NA from 0.95 to 0.60. In future work, we plan to test the main conclusions of this work using standalone and long-period structures.
Micellar Growth in Cetylpyridinium Chloride/Alcohol System: Role of Long Chain Alcohol, Electrolyte and Surfactant Head Group (2016)

Abstract The microstructural transition of aqueous 0.1 M cetylpyridinium chloride (CPC) in the combined presence of salt KBr and long chain alcohol (C 9 OH‐C 12 OH) has been studied as a function of alcohol concentration, electrolyte concentration and temperature. The viscosity of the CPC/KBr micellar system showed a peaked behavior with alcohol concentration ( C 0 ), due to alcohol induced structural transition, which was confirmed by dynamic light scattering (DLS) and rheological analysis. Besides C 0 , the chain length of alcohol ( n ) was found to show a remarkable effect on the micellization behavior of CPC/KBr system. It was observed that the ability of alcohol to induce micelle growth diminishes with n , which was well supported by viscosity, rheology and DLS measurements. To examine the effect of the electrolyte on the micellar growth, the salt concentration was varied from 0.05 to 0.15 M and it was observed that with increase in [KBr], the peak position shifts towards lower C 0 . The effect of temperature on the micellar system showed interesting phase behavior for CPC/KBr/Decanol. The system exhibited a closed solubility loop with an upper critical solution temperature (UCST) &gt; the lower critical solution temperature (LCST), reminiscence of nicotine‐water system. The role of surfactant head group on the structural evolution was revealed by comparing the present results with our previous report for similar micellar system, CTAB/KBr/long chain alcohol.
Food Waste Ontology: A Formal Description of Knowledge from the Domain of Food Waste (2019)

Recently, as a part of an EU-funded project called REFRESH, a new web-based tool named FoodWasteEXplorer was developed. It provides an easy access to valuable data on unavoidable food waste that can be explored by researchers, industry, governmental agencies and the public to find ways of its valorization. The food waste data was manually collected and stored in a relational database. To enrich and make best use of it, we automatically transform the collected information into a new food waste ontology. The created Food Waste Ontology provides a formal description of knowledge from the food waste domain. Examples of its application are: (i) database querying based on natural language questions, and (ii) finding new or missing data from other datasets.
Endobronchial Cartilage Rupture: A Rare Cause of Lobar Collapse (2016)

Endobronchial cartilage rupture is a rare clinical condition, which can present in patients with severe emphysema with sudden onset shortness of breath. We present a case of a 62-year-old male who presented to our emergency department with sudden onset shortness of breath. Chest X-ray showed lung hyperinflation and a right lung field vague small density. Chest Computed Tomography confirmed the presence of right middle lobe collapse. Bronchoscopy revealed partial right middle lobe atelectasis and an endobronchial cartilage rupture. Endobronchial cartilage rupture is a rare condition that can present as sudden onset shortness of breath due to lobar collapse in patients with emphysema and can be triggered by cough. Bronchoscopic findings include finding a collapsed lung lobe and a visible ruptured endobronchial cartilage. A high index of suspicion, chest imaging, and early bronchoscopy can aid in the diagnosis and help prevent complications.

Redistribution of NMDA Receptors in Estrogen-Receptor-β-Containing Paraventricular Hypothalamic Neurons following Slow-Pressor Angiotensin II Hypertension in Female Mice with Accelerated Ovarian Failure (2016)

Hypertension in male and aging female rodents is associated with glutamate-dependent plasticity in the hypothalamus, but existing models have failed to capture distinct transitional menopausal phases that could have a significant impact on the synaptic plasticity and emergent hypertension. In rodents, accelerated ovarian failure (AOF) induced by systemic injection of 4-vinylcyclohexane diepoxide mimics the estrogen fluctuations seen in human menopause including the perimenopause transition (peri-AOF) and postmenopause (post-AOF). Thus, we used the mouse AOF model to determine the impact of slow-pressor angiotensin II (AngII) administration on blood pressure and on the subcellular distribution of obligatory N-methyl-D-aspartate (NMDA) receptor GluN1 subunits in the paraventricular hypothalamic nucleus (PVN), a key estrogen-responsive cardiovascular regulatory area. Estrogen-sensitive neuronal profiles were identified in mice expressing enhanced green fluorescent protein under the promoter for estrogen receptor (ER) β, a major ER in the PVN. Slow-pressor AngII increased arterial blood pressure in mice at peri- and post-AOF time points. In control oil-injected (nonhypertensive) mice, AngII decreased the total number of GluN1 in ERβ-containing PVN dendrites. In contrast, AngII resulted in a reapportionment of GluN1 from the cytoplasm to the plasma membrane of ERβ-containing PVN dendrites in peri-AOF mice. Moreover, in post-AOF mice, AngII increased total GluN1, dendritic size and radical production in ERβ-containing neurons. These results indicate that unique patterns of hypothalamic glutamate receptor plasticity and dendritic structure accompany the elevated blood pressure in peri- and post-AOF time points. Our findings suggest the possibility that distinct neurobiological processes are associated with the increased blood pressure during perimenopausal and postmenopausal periods.
[Prevalence of antibodies against herpes simplex virus, Epstein-Barr virus and cytomegalovirus in a group of patients after hemodialysis]. (2000)

Infections from herpes virus play a key role in post-transplantation pathology, so it is indispensable to characterize the group of would-be renal transplant recipients. IgG antibody titers were detected by indirect immunofluorescence to Herpes simplex virus, Epstein Barr virus (EBV) and cytomegalovirus (CMV) in 100 patients treated with hemodialysis in the Nephrology Institute. The prevalence of antibodies to cytomegalovirus and to Herpes simplex and Epstein Barr viruses was 100% and 95% respectively. Average geometric titers (AGT) of antibodies to CMV were significantly higher. There was no correlation between AGT and sex, age, time of disease remission, number of blood transfusions and number of transplants.
(NH4)8[Ce2(SO4)8] .4H2O (1998)

Crystals of the title compound, octaammonium dicerium octasulfate tetrahydrate, suitable for X-ray work, were prepared by a hydrothermal reaction. The structure is made up of [Ce2(SO4)8]8- anions, interacting with the crystallization waters and the NH4+ cations through hydrogen bonds. The CeIV atom in the [Ce2(SO4)8]8- anion is ninefold coordinated by O atoms belonging to sulfate groups. The coordination polyhedron is a somewhat distorted tricapped trigonal prism. The Ce-O distances range from 2.325(2) to 2.478(2) A.
Concepts for science autonomy during robotic traverse and survey (2005)

Future Mars rovers will have the ability to autonomously navigate for distances of kilometers. In one sol a traverse may take a rover into unexplored areas beyond its local horizon. Naturally, scientists cannot specify particular targets for the rover in an area they have not yet seen. This paper analyzes what they can specify: priorities that provide the rover with enough information to autonomously select science targets using its onboard sensing. Several autonomous science operational modes and priority types are discussed. We also introduce a science priority language. A team of scientists was asked to use the language in specifying targets for a teleoperated rover, and qualitative results are reported.
Evaluation of a Commercial Echinococcus Western Blot Assay for Serological Follow-Up of Patients with Alveolar Echinococcosis (2008)

A total of 20 patients with alveolar echinococcosis in different clinical stages according to the WHO-PNM staging system (P, parasitic mass in the liver; N, involvement of neighboring organs; M, metastasis) were followed up serologically with the commercial Echinococcus Western Blot IgG assay and a crude antigen extract enzyme-linked immunosorbent assay (ELISA). The cohort included patients after curative resection and patients who had unresectable lesions with stable disease or progressive infection. There were visible correlations of the crude antigen ELISA index and the presence and intensity of diagnostic bands in the Western blot. In most patients after curative resection, bands at 7, 16, and 18 kDa markedly decreased or vanished after 1 to 4 years. In a patient with a nonviable lesion (it died out), bands at 16 and 18 kDa vanished after 4 years. Among individuals with unresectable lesions but stable disease under antiparasitic chemotherapy, a decrease of all diagnostic bands was visible after 2 to 3 years in half of the patients, whereas the other half had unchanged blot results after 4 to 6 years. Patients with progressive disease showed increasing intensities of bands at 16, 18, and 7 kDa. The change of banding patterns was not influenced by the PNM stage in patients after curative surgery or with unresectable lesions. Our data indicate a correlation of the 7-, 16-, and 18-kDa-Western blot bands with disease activity independent of the PNM stage. This study demonstrated the usefulness of the Echinococcus Western Blot IgG assay as an additional serological test for the follow-up of patients with alveolar echinococcosis.
Automating the selection of code templates (1985)

Abstract A new methodology for code generation in compilers is advanced. The underlying principle is a simple one—that machine memory resources must be matched to intermediate code values. It is possible to view the methodology as a generalization of the Graham‐Glanville approach, but where there is a wider‐ranging search for the best code sequences. This new approach has been implemented for the IBM/370, the VAX‐11 and the Intel 8086 instruction sets.
Prevalence, Expenditures, and Complications of Multiple Chronic Conditions in the Elderly (2002)

The risk of an avoidable inpatient admission or a preventable complication in an inpatient setting increases dramatically with the number of chronic conditions. Better primary care, especially coordination of care, could reduce avoidable hospitalization rates, especially for individuals with multiple chronic conditions.
Small RNAs activate Salmonella pathogenicity island 1 by modulating mRNA stability through the hilD mRNA 3′ UTR (2022)

Abstract Salmonella enterica serovar Typhimurium is an enteric pathogen associated with food-borne disease. Salmonella invades the intestinal epithelium using a type three secretion system encoded in Salmonella pathogenicity Island 1 (SPI-1). SPI-1 genes are tightly regulated by a complex feed-forward loop to ensure proper spatial and temporal expression. Most regulatory input is integrated at HilD, through control of hilD mRNA translation or HilD protein activity. The hilD mRNA possesses a 310-nucleotide 3′ untranslated region (UTR) that influences HilD and SPI-1 expression, and this regulation is dependent on Hfq and RNase E, cofactors known to mediate small RNA (sRNA) activities. Thus, we hypothesized that the hilD mRNA 3′ UTR is a target for sRNAs. Here we show that the sRNAs, SdsR and Spot 42 regulate SPI-1 by targeting different regions of the hilD mRNA 3′ UTR. Regulatory activities of these sRNAs depend on Hfq and RNase E, in agreement with previous roles found for both at the hilD 3′ UTR. We show that SdsR and RNase E are responsible for the accumulation of variable fragments of the hilD mRNA 3′ UTR. Collectively, this work suggests that these sRNAs targeting the hilD mRNA 3′ UTR regulate hilD mRNA levels by interfering with RNase E-dependent mRNA degradation. Our work provides novel insights into mechanisms of sRNA regulation at bacterial mRNA 3′ UTRs and adds to our knowledge of post-transcriptional regulation of the SPI-1 complex feed-forward loop. Importance Salmonella are prominent food-borne pathogens, infecting millions of people a year. To express virulence genes at the correct time and place in the host, Salmonella uses a complex regulatory network that senses environmental conditions. Known for their role in allowing quick responses to stress and virulence conditions, we investigate the role of small RNAs in facilitating precise expression of these genes. We provide evidence that the 3′ untranslated region of the hilD mRNA, encoding a key virulence regulator, is a target for small RNAs and the ribonuclease RNase E. The small RNAs play a role in stabilizing hilD mRNA to allow proper expression of Salmonella virulence genes in the host.
Molecular force modeling of lithography (Conference Presentation) (2017)

Figure would be provided Figure 1 shows that the most important factor in lithography is foot contrast. Low contrast leaves a large region (CAT) where resist solubility is uncertain (chaotic area), which causes unresolvable patterns, LER/LWR issues, and pattern collapse (collapse may be due to affinity imbalance). Figure 2 shows examples of a CAT plot for two stacks of low optical reflectivity and high optical foot contrast. Low reflectivity gives higher CAT, and is further deteriorated as the image approaches the forbidden pitch, while a high foot contrast stack keeps good CAT value across all pitches. Experimental results agree well with the calculations, which will be included in the full paper. Figure 3 is a CAT contour map versus resist and Si-HM thickness for a L/P=40/100 nm pattern. Additional CAT plots will be included in the full paper. Figure 1. Optical distribution of a 40-nm dense line cross-section and resist contrast curve for CAT calculation. Figure 2.
