In situ method of inspecting anchor rods for section loss using the cylindrically guided wave technique (1996)

A nondestructive evaluation technique has been developed to measure and analyze section loss due to corrosion for anchor rods used in guying steel transmission poles. The anchor guy system tested consists of a steel plate embedded in concrete connected to a steel rod buried in earth and attached to the guy wire from the pole. The method used was ultrasonics and, specifically, the cylindrically guided wave technique (CGWT). Field correlation of the method was verified by digging up and inspecting several rods. This approach has optimized the ultimate replacement and maintenance expense.
Plasma and cerebrospinal fluid pharmacokinetics of 5-Aza-2'-deoxycytidine in rabbits and dogs. (1983)

5-Aza-2'-deoxycytidine (5-aza-dCyd) is an effective antileukemic agent. In view of the importance for an antileukemic agent to cross effectively the blood-brain-barrier, we studied the plasma and cerebrospinal fluid (CSF) pharmacokinetics of this drug in rabbits and dogs. The 5-aza-dCyd concentrations in biological fluids were determined by bioassay and high-performance liquid chromatography. 5-Aza-dCyd was administered either as an i.v. bolus or as a continuous i.v. infusion following a loading dose. Blood and CSF samples were collected at various time intervals. After an i.v. bolus, the plasma disappearance of 5-aza-dCyd was biphasic with half-lives of 5 and 43 min in rabbits and of 5 and 75 min in dogs. The apparent volume of distribution at steady state was in the order of 800 ml/kg for both species. The total plasma clearance of the drug was 15 ml/min/kg in rabbits and 9 ml/min/kg in dogs. After a 180 min i.v. infusion, 5-aza-dCyd slow disappearance half-lives were of 39 min in rabbits and of 144 min in dogs. The 5-aza-dCyd concentrations attained in the CSF were 27 and 58% of the plateau plasma concentration in rabbits and dogs, respectively. The drug disparition from the CSF followed closely the plasma profile after an i.v. infusion with a somewhat longer half-life. These results showed that 5-aza-dCyd can cross the blood-CSF barrier effectively, producing cytotoxic concentrations in the CSF when given by i.v. infusion.

Prognosis and disability of stroke patients after 5 years in Akita, Japan. (1990)

The system of registering stroke patients was begun in 1963 in Ikawa Town, Akita Prefecture, Japan. The town is located in the northeastern part of the country and in 1975 had a population of 6,427. From 1975 to 1981, 109 patients who suffered their first stroke were registered and were monitored for 5 years. The average annual incidence rates of stroke were 2.8 and 2.0 per 1,000 population in males and females, respectively. Mean age at stroke onset was 63.3 and 71.4 years in males and females, respectively (p less than 0.01). According to the clinical classification of stroke, 76 patients suffered cerebral infarction, 21 cerebral bleeding, and six subarachnoid hemorrhage; six strokes were unclassified. The survival rates were compared by sex, age, and clinical stroke type using Cox's proportional hazards model. The survival rate of female stroke patients was lower than that of males, but not significantly so. The survival rate of stroke patients greater than or equal to 65 years old was significantly lower (p less than 0.01) than that of younger patients. Moreover, the survival rate of patients with cerebral bleeding was significantly lower (p less than 0.01) than that of patients with cerebral infarction. In the analysis of self-care among the survivors, performance of the activities of daily living in older patients indicated significantly less independence (p less than 0.01) in younger patients. Follow-up of new stroke cases showed that age and clinical stroke type were significantly associated with survival and that age was also related to disability of the survivors.
Exercise, Mitohormesis, and Mitochondrial ORF of the 12S rRNA Type-C (MOTS-c) (2022)

Low levels of mitochondrial stress are beneficial for organismal health and survival through a process known as mitohormesis. Mitohormetic responses occur during or after exercise and may mediate some salutary effects of exercise on metabolism. Exercise-related mitohormesis involves reactive oxygen species production, mitochondrial unfolded protein response (UPRmt), and release of mitochondria-derived peptides (MDPs). MDPs are a group of small peptides encoded by mitochondrial DNA with beneficial metabolic effects. Among MDPs, mitochondrial ORF of the 12S rRNA type-c (MOTS-c) is the most associated with exercise. MOTS-c expression levels increase in skeletal muscles, systemic circulation, and the hypothalamus upon exercise. Systemic MOTS-c administration increases exercise performance by boosting skeletal muscle stress responses and by enhancing metabolic adaptation to exercise. Exogenous MOTS-c also stimulates thermogenesis in subcutaneous white adipose tissues, thereby enhancing energy expenditure and contributing to the anti-obesity effects of exercise training. This review briefly summarizes the mitohormetic mechanisms of exercise with an emphasis on MOTS-c.
Evaluation and Management of Subchondral Calcium Phosphate Injection Technique to Treat Bone Marrow Lesion (2018)

Few studies evaluate the result of using subchondral calcium phosphate injection technique. However, all presented favorable results regarding pain and improvement of knee function. In addition, within 2 years, there was a 70% reduction in conversion to total knee arthroplasty in patients with previous surgical indication who choose calcium phosphate treatment.
Un Parlement pour l'Europe: Quand le lobbyng sert les eurodéputés (1997)

The synthesis of structurally ordered non-noble intermetallic cobalt stannide (CoSn<sub>2</sub> ) nanocrystals and their utilization for high-performance electrocatalytic overall water-splitting is presented. The structurally and electronically beneficial properties of the tetragonal CoSn<sub>2</sub> exhibit a considerably low overpotential for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) on fluorine-doped tin oxide (FTO) and Ni foam (NF). Loss of Sn from the crystal lattices and oxidation of Co under strongly alkaline conditions furnishes highly disordered amorphous active CoO<sub>x</sub> (H), the catalytically active structure for OER. The Co<sup>0</sup> atoms in the CoSn<sub>2</sub> act as active sites for HER and the presence of Sn provides efficient electrical conductivity. This intermetallic phase is a novel type of cost-effective and competitive bifunctional electrocatalysts and predestinated for overall water-splitting devices: A two-electrode electrolyzer with CoSn<sub>2</sub> on NF delivers a cell voltage of merely 1.55 V at 10 mA cm<sup>-2</sup> maintaining long-term stability.
Resistance of some common fungi to gamma irradiation (1988)

Ten species of fungi representing the genera Alternaria, Aspergillus, Caldosporium, Curvularia, Fusarium, and Penicillium were examined for their relative resistance to gamma irradiation from a 137Cs source. Inactivation doses for dematiaceous fungi in agar medium ranged from 0.6 to greater than 1.7 megarads, whereas those for moniliaceous fungi were less than 0.3 megarad. D10 values (the dose required to reduce the inoculum by 1 log) for Curvularia geniculata (greater than 0.29 megarad) exceeded those for control spores of Bacillus pumilus (0.15 megarad).
Moisture Absorption Characteristics of Pt/Nafion Membrane for PEMFC Prepared by a Drying Process (2012)

Abstract >> A simple drying process was developed for the preparation of a Pt/Nafion self-humidifying membraneto be used for a proton-exchange membrane fuel cell (PEMFC). Platinum (II) bis (acetylacetonate), Pt(acac) 2 was sublimed, penetrated into the surface of a Nafion film and then reduced to Pt nanoparticles simultaneously withoutany support of a reducing agent in a glass reactor at 180 o C for 15 min. The process was carried out in N 2 atmosphereto prevent the oxidation of Pt nanoparticles at high temperature. The morphology and distribution of the Pt nanoparticles were observed by transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS),and we found that the average Pt particle size was ca. 3.7 nm, the penetration depth was ca. 17 μm. Almost all Pt nanoparticles were formed just beneath the surface and the number density decreased rapidly as the penetrationdepth increased. To estimate water absorption characteristics of the Nafion membranes, water uptake at an isothermal condition was measured by dynamic vapor sorption (DVS), and it was found that water uptake of the Pt/Nafion membrane was higher than that of the neat Nafion membrane.
Laparoscopic Spleen Preserving Distal Pancreatectomy with the Conservation of the Splenic Artery and the Vein (2003)

Until now, there have been few reports of laparoscopic spleen preserving distal pancreatectomies with the conservation of the splenic vessels. We experienced two cases of a laparoscopic spleen preserving distal pancreatectomy, with the conservation of the splenic artery, vein and short gastric vessels. One case was in a 52 years old woman. The patient was preoperatively diagnosed with a nonsymptomatic cystadenoma, which measured 7 cm in diameter at the tail of pancreas. The procedure used was a 70% distal pancreatectomy, with preservation of the spleen, including the splenic vessels. Three 10 mm ports, one 15mm port and one linear stapler () were used for the procedure. A 3 cm incision, extending 15 mm to the trocar site, was used for the extraction of the specimen. The total operative time was 435 minutes. The patient was discharged on the 8th postoperative day with no problems. The other case was in a 61 years old woman. The patient was preoperatively diagnosed with a symptomatic cystadenoma, which measured 3 cm in size at the body of the pancreas. The procedure used was an 85% distal pancreatectomy, employed the same method as the previous case, with the exception that an was used for the resection of pancreas in place of the . The total operative time was 400 minutes. The patient was discharged on 9th postoperatvie day, with no problems. There was no morbidity and mortality during hospitalization. A laparoscopic spleen splenic vessels, could be an alternative treatment in selectivepreserving distal pancreatectomy with the conservation of the patients with benign pancreatic neoplasms.
SoK: Fully Homomorphic Encryption Compilers (2021)

Fully Homomorphic Encryption (FHE) allows a third party to perform arbitrary computations on encrypted data, learning neither the inputs nor the computation results. Hence, it provides resilience in situations where computations are carried out by an untrusted or potentially compromised party. This powerful concept was first conceived by Rivest et al. in the 1970s. However, it remained unrealized until Craig Gentry presented the first feasible FHE scheme in 2009.The advent of the massive collection of sensitive data in cloud services, coupled with a plague of data breaches, moved highly regulated businesses to increasingly demand confidential and secure computing solutions. This demand, in turn, has led to a recent surge in the development of FHE tools. To understand the landscape of recent FHE tool developments, we conduct an extensive survey and experimental evaluation to explore the current state of the art and identify areas for future development.In this paper, we survey, evaluate, and systematize FHE tools and compilers. We perform experiments to evaluate these tools’ performance and usability aspects on a variety of applications. We conclude with recommendations for developers intending to develop FHE-based applications and a discussion on future directions for FHE tools development.
Enhancement of immunogenicity of tumour virus antigen by liposomes: the effect of lipid composition. (1986)

The secondary humoral response evoked in W/Fu rats by the weakly immunogenic soluble Gross cell surface antigen (GCSAa) extracted from the syngeneic (C58NT)D lymphoma can be enhanced when GCSAa is presented in liposomes, and this requires the antigen to be strongly associated with the phospholipid bilayers. In order to investigate further the role of the phospholipid microenvironment in the membrane presentation of this antigen, the relationship between the phospholipid composition and the immunogenic potency of GCSAa liposomes was explored. For a given neutral phospholipid component, optimal immunogenicity was obtained when 20% cholesterol was present and when a negatively charged phospholipid was included as a minor component. When phosphatidylcholines (PC) were used as the major neutral component, the immunogenicity of GCSAa liposomes from optimal for distearoyl PC (DSPC) decreased when decreasing the PC acyl chain length down to the background level for dilauroyl PC (DLPC). Similarly, the use of PC with acyl chain of increasing unsaturation was followed by a decline in the immunogenicity of the GCSAa liposomes up to the background level for dilinoleoyl PC (DLiPC). Replacing PC headgroups by phosphatidylethanolamine (PE) headgroups abolished the enhancing effect of the liposome presentation on GCSAa immunogenicity. Three groups of phospholipids unable to promote the expression of the GCSAa immunogenicity could be distinguished: the DLPC, DLiPC group, unable to prime the animals but, contrary to the soluble antigen, able to boost the animal after an appropriate priming with GCSAa-DSPC-liposomes, the dimyristoyl PE group, unable to prime or to boost and non-toxic in vitro for the macrophages, and the dipalmitoyl PE group, acutely toxic for macrophages.
Mac-1 antigen: quantitative expression in macrophage populations and tissues, and immunofluorescent localization in spleen. (1982)

Abstract The extent of Mac-1 expression by different macrophage populations and tissues has been examined and contrasted to that of la. Mac-1 is expressed on &gt;86% of unelicited peritoneal macrophages as well as on macrophages elicited by thioglycollate, Con A, LPS, Listeria monocytogenes, or peptone, as determined by immuno-fluorescent flow cytometry analysis. All populations express similar quantities of Mac-1 /cell. The number of 125I-M1/70 MAb bound per thioglycollate-elicited macrophage is 1.6 × 105 at saturation. Immunoprecipitation from 35S-methionine labeled cells confirmed that macrophages elicited by diverse agents contain similar amounts of Mac-1 polypeptides of 170,000 and 95,000 Mr. In contrast, the amount of la antigen in Con A- or Listeria-elicited macrophages is much higher than in unelicited macrophages or macrophages elicited by LPS or thioglycollate. Mac-1 is thus a general marker for macrophages elicited by different means, even though the macrophages differ widely in functional activities and in la antigen expression. Tissue absorption studies show that the amount of Mac-1 expressed by spleen and bone marrow is 5 and 7% that of thioglycollate-elicited peritoneal exudate cells (PEC), respectively. Lung and liver weakly absorb 125I-M1/70 whereas heart, kidney, and brain are not absorptive. When used in indirect immuno-fluorescent staining of frozen spleen sections, M1/70 intensely stains cells with macrophage morphology in splenic red pulp and marginal zone, but not the T-dependent areas of white pulp.
Modeling and Simulation of a Simulated Moving Bed for the Separation of <i>p</i>-Xylene (2002)

The industrial-scale adsorptive separation of p-xylene from a mixture of C8 aromatics in a four-section simulated moving bed (SMB) unit is analyzed through simulation. In the order to describe the behavior of the SMB unit by means of a mathematical model, two approaches were used: the true moving bed (TMB) approach and the SMB approach. Both approaches assume a constant selectivity nonstoichiometric Langmuir isotherm, an axial dispersion for the fluid flow, and a linear driving force for the intraparticle mass transfer. The TMB and SMB model predictions of steady-state performance of the SMB unit are very close. Therefore, the TMB model was selected to study the effect of the switching time period, adsorbent deactivation, and mass-transfer resistances on the process performance. The adsorbent deactivation which occurs during its lifetime will influence the SMB performance; to keep the p-xylene purity and acceptable recovery, the switching time should be decreased. The TMB package is a useful tool for fast visualization of the SMB process behavior under particular operating conditions. The novel “separation volume” methodology is used to find the operating conditions of the SMB unit in the presence of mass-transfer resistances.
An integrated process for system maintenance, fault diagnosis and support (1999)

This paper presents an overview of an integrated process for system maintenance, fault diagnosis and support. The solution is based on Qualtech Systems, Inc.'s (QSI's) TEAMS toolset for integrated diagnostics and involves several key innovations. As a showcase of the integrated solution, QSI, along with Antech Systems and Carnegie Mellon University (CMU), have recently completed a research project for the Information Technology Branch at the Naval Air Warfare Center-Aircraft Division (NAWC-AD) in St. Inigoes, MD. The project involved enhancing, customizing and integrating the QSI toolset with interactive electronic technical manuals (IETMs), whose display automatically adapts to the technical capabilities of the technician using the system. The entire system, termed ADAPTS (Adaptive Diagnostic And Personalized Technical Support), provides comprehensive solution to integrated maintenance and training. This paper describes the architecture of different QSI modules and their overall integration into comprehensive system maintenance, diagnostic and support system, as implemented in the ADAPTS system.
A sulfur host based on titanium monoxide@carbon hollow spheres for advanced lithium–sulfur batteries (2016)

Lithium-sulfur batteries show advantages for next-generation electrical energy storage due to their high energy density and cost effectiveness. Enhancing the conductivity of the sulfur cathode and moderating the dissolution of lithium polysulfides are two key factors for the success of lithium-sulfur batteries. Here we report a sulfur host that overcomes both obstacles at once. With inherent metallic conductivity and strong adsorption capability for lithium-polysulfides, titanium monoxide@carbon hollow nanospheres can not only generate sufficient electrical contact to the insulating sulfur for high capacity, but also effectively confine lithium-polysulfides for prolonged cycle life. Additionally, the designed composite cathode further maximizes the lithium-polysulfide restriction capability by using the polar shells to prevent their outward diffusion, which avoids the need for chemically bonding all lithium-polysulfides on the surfaces of polar particles.
Carcinoma of the esophagus. Pretreatment assessment, correlation of radiation treatment parameters with survival, and identification and management of radiation treatment failure (1979)

Between January 1969 and February 1975, 344 patients with carcinoma of the esophagus were managed primarily at the Princess Margaret Hospital, Toronto. One hundred sixty-eight (168) of the patients were treated palliatively and 176 of the patients were treated by radical doses of radiation, surgical resection or both. Survival of the radical treatment group was biphasic, the steeper component being identical to the survival of the palliative treatment group, thereby representing a group of patients that did not respond to radical treatment. Analysis of pretreatment assessment parameters indicated that all patients with T1 lesions (length ⩽5 cm, circumference incomplete) and all patients with Stage I disease responded to treatment. Patients who were female, age ⩾70 years, No or had well differentiated squamous cell histology, responded to treatment in at least 80% of cases. No patient with extralymphatic distant metastases responded to treatment. The presence of other major disease did not affect response to treatment. Thirty patients had surgical resections and their survival was not significantly greater than the 146 patients who had radical radiation alone. Survival analysis revealed an optimum range of nominal standard dose (NSD) of 1602-1714 rets (median 1679 rets) for patients treated by radiation alone. An optimum port size (area) of 100-140 cm2 was observed for patients receiving 5000 rads and supervoltage irradiation gave a significantly improved survival in comparison with megavoltage irradiation. Sixty-seven percent (67%) of patients treated by radical doses of radiation developed esophageal strictures postradiation and on the basis of radiological, endoscopic or histological evidence 75% of these strictures were considered to be associated with the persistence of malignancy. On the basis of postmortem examinations (32) and death certificates there was overall an 80% failure to control the disease locally and 95% of strictures were associated with persistence of malignancy in the esophagus. Thirty-one of the 146 patients receiving radical radiation alone had palliation for esophageal obstruction following radiotherapy. The construction of a physiological bypass (e.g., colon) resulted in a mean survival of 215 days which was much longer than the survival observed with rigid esophageal tubes (35 days) or gastrostomy tubes (58 days).

Peak to average power ratio reduction for digital video broadcast T2 (2011)

The recently published DVB-T2 standard provides for the use of two separate methods directed at reducing the signal peak to average power ratio. This paper investigates the effectiveness of the Active Constellation Extension method, and the Reserve Carrier Algorithm method through the use of simulations using Matlab software. Enhanced performance is demonstrated by using both techniques simultaneously.
