Invasive Intraductal Papillary Mucinous Neoplasms: CT Features of Colloid Carcinoma Versus Tubular Adenocarcinoma of the Pancreas (2020)

<b>OBJECTIVE.</b> The purpose of this study is to compare the CT features of colloid carcinoma and tubular adenocarcinoma of the pancreas arising in association with intraductal papillary mucinous neoplasms (IPMNs). <b>MATERIALS AND METHODS.</b> The preoperative CT images of 85 patients with histopathologically proven IPMNs and associated invasive adenocarcinoma located next to each other were retrospectively reviewed. Twenty-nine patients (34.1%; 19 men and 10 women; mean [± SD] age, 68.0 ± 9.5 years) had invasive colloid carcinoma, and 56 patients (65.9%; 31 men and 25 women; mean age, 70.8 ± 10.6 years) had invasive tubular adenocarcinoma. We compared the following CT features between the two groups: IPMN type, main pancreatic duct (MPD) and common bile duct diameters, diameter and characteristics of the largest cystic lesion for branch duct and mixed-type IPMNs, presence of an extracystic or extraductal solid mass next to the cystic lesion or MPD, morphologic features of the upstream MPD in relation to the cystic lesion or solid mass, and presence of a fistula to the adjacent organs. <b>RESULTS.</b> An MPD size of 9.5 mm or greater, a largest cystic lesion diameter of 28 mm or greater, location in the head or neck, septation, calcification, presence of a mural nodule(s) within a cystic lesion or MPD, and presence of a fistula were all more commonly associated with colloid carcinoma. In contrast, presence of an extracystic or extraductal solid mass and an abrupt change in the caliber of the dilated MPD were associated with tubular adenocarcinoma. The best CT feature for differentiating between the two groups was the morphologic features of the upstream MPD in relation to the cystic lesion or solid mass (sensitivity, 81.3%; specificity, 92.3%). <b>CONCLUSION.</b> Preoperative CT is helpful in differentiating two types of invasive carcinoma arising in association with IPMNs. These findings are clinically important because prognosis is better for colloid carcinoma than for tubular adenocarcinoma.

Facile syntheses of dissymmetric ferrocene-functionalized Lewis acids and acid–base pairs (2009)

A facile synthetic approach is reported for the synthesis of dissymmetric 1,2-ferrocenediyl Lewis acids and mixed acid-base pairs including the first example of a 1-phosphino-2-borylferrocene; the use of non-racemic electrophiles allows for the isolation of single diastereomer products.
Application of Magic-Angle Spinning NMR to Examine the Nature of Protons in Titanate Nanotubes (2010)

Systematic magic-angle spinning (MAS) 1H NMR studies of protonated titanate nanotubes (produced by alkaline hydrothermal treatment of TiO2 with NaOH) have revealed that there are several types of protons incorporated into their wall structure, including crystallographic water molecules and ion-exchangeable OH groups. Each type (a) has a characteristic chemical shift and (b) disappears at a different rate during annealing in air. The evolution of protons in titanate nanotubes during crystallographic and morphological transformation in the sequence H2Ti3O7·xH2O, H2Ti3O7, H2Ti6O13, TiO2(B), TiO2(anatase) during calcination, at temperatures from 140 to 500 °C, has been studied using MAS NMR and Raman spectroscopies together with thermogravimetric analysis (TGA), X-ray diffraction (XRD) and transmission electron microscopy (TEM) techniques. The irreversible disappearance of ion-exchangeable OH groups has been observed, even under low temperature treatment.
Making the VoiceWeb smarter - integrating intelligent component technologies and VoiceXML (2002)

VoiceXML offers the prospect of a streamlined deployment process of voice interfaces for commercial applications, similar to the ease of Web development. This in turn promises increased dynamism in the field of speech and language research. We investigate opportunities and constraints for the integration of intelligent component technologies into VoiceXML-based systems: such components will solve tasks from both sides of natural language processing, natural language understanding/analysis as well as natural language generation. We ask what role these fields originating from AI research will play in the VoiceXML environment. For a more detailed report including also the issues of multilinguality and natural language interfaces see (Mittendorfer et al., 2001).
The Molecular Basis of Functional Bacterial Amyloid Polymerization and Nucleation (2008)

Amyloid fibers are filamentous proteinaceous structures commonly associated with mammalian neurodegenerative diseases. Nucleation is the rate-limiting step of amyloid propagation, and its nature remains poorly understood. Escherichia coli assembles functional amyloid fibers called curli on the cell surface using an evolved biogenesis machine. In vivo, amyloidogenesis of the major curli subunit protein, CsgA, is dependent on the minor curli subunit protein, CsgB. Here, we directly demonstrated that CsgB(+) cells efficiently nucleated purified soluble CsgA into amyloid fibers on the cell surface. CsgA contains five imperfect repeating units that fulfill specific roles in directing amyloid formation. Deletion analysis revealed that the N- and C-terminal most repeating units were required for in vivo amyloid formation. We found that CsgA nucleation specificity is encoded by the N- and C-terminal most repeating units using a blend of genetic, biochemical, and electron microscopic analyses. In addition, we found that the C-terminal most repeat was most aggregation-prone and dramatically contributed to CsgA polymerization in vitro. This work defines the elegant molecular signatures of bacterial amyloid nucleation and polymerization, thereby revealing how nature directs amyloid formation to occur at the correct time and location.
199. Prospective Observational Cohort Of Transition to Oral Antibiotics in Persons Who Inject Drugs with Invasive Infections (2021)

Abstract Background Persons who inject drugs (PWID) are at increased risk of invasive bacterial infections. Increasing data supports the efficacy of transition to oral antibiotic therapy to complete treatment of invasive bacterial infections including osteomyelitis and endocarditis. The aim of this study is to evaluate the impact of transition to oral antibiotics on a prospective observational cohort of PWID. Methods We prospectively analyzed PWID admitted 2/2020 - 2/2021 at Barnes-Jewish Hospital in St. Louis with osteomyelitis, endocarditis, epidural abscesses or septic arthritis. All patients were offered multidisciplinary support during their inpatient hospitalization including addiction medicine consultation and medications for opioid use disorder, if appropriate. Health coaches and case managers met with patients during their hospitalization and followed patients for up to 90 days after discharge. Patients were offered the option of transition to oral antibiotics if they were not able to complete recommended IV antibiotics. Patients discharged on oral antibiotics were offered post-discharge infectious diseases follow-up. Antibiotic adherence was documented by health coaches through phone out-reach. We collected data on demographics, comorbidities, microbiologic data, antibiotic selection, mortality and readmission rates. We compared 90-day readmission rates between PWID who completed IV antibiotics inpatient and those who discharged early with oral antibiotics. Results Of 166 PWID, 61 completed IV antibiotics inpatient (37%) while 105 were discharged with oral antibiotics (63%). Causative pathogens were not significantly different between inpatient IV vs oral antibiotics; MSSA (34.4% vs 35.2%, p= 0.92), MRSA (34.4% vs. 28.6%, p=0.43), or streptococcal species (26.6% vs. 24.8%, p=0.85). Of patients discharged on oral antibiotics 7.6% had documented non-adherence to therapy, 23% had unknown adherence and 67% had documented adherence. There was no significant difference in all-cause 90-day readmission rates (p=0.819) (Figure 1). All-cause readmissions by antibiotic strategy Conclusion Oral antibiotic regimens provided similar efficacy to IV antibiotics in our prospective cohort analysis of PWID.

<title>Optical sensor research at Virginia Tech Center for Photonics Technology</title> (2002)

Optical sensors that can be used in harsh environments are desirable in a wide range of industrial and military applications where conventional measurement devices are difficult to apply due to the harsh environments. Optical fiber sensors have been demonstrated to be attractive for the measurement of a wide variety of physical parameters because of such inherent advantages as 1) small size, 2) an immunity to electromagnetic interference, 3) high resolution, 4) non-electrically conducting, 5) capability of responding to a wide variety of measurands, 6) avoidance of electric sparks, 7) resistance to harsh environment, 8) remote operation, and 9) capability of multiplexing. In the past two decades, fiber sensors have been demonstrated and developed. The optical sensor research at the Virginia Tech Center for Photonics Technology (VTCPT) has been mainly focused on the development of sensors for measurement of pressure, temperature, strain, acoustic waves, flow, electric partial discharges, surface mapping and 3-D temperature imaging. Most of these sensors are based on optical fibers, including silica glass fiber with various polymer and metallic coatings and single-crystal sapphire fiber waveguides. In terms of the optical parameters being modulated, these sensors could be approximately classified into interferometric, polarimetric, intensity-based, and wavelength-coded devices. This paper presents several examples of the sensors recently developed at Virginia Tech.
Erratum: “Experimental and Theoretical Investigation of Bouncing Vibrations of a Flying Head Slider in the Near-Contact Region” [Journal of Tribology, 2007, 129(2), pp. 246–255] (2009)

(1) Equation 4 should be rewritten as 4cf=2ζfMkf,cr=2ζrMkr(2) In Table 1, the parameter values should be rewritten as follows:M=1.918mg (effective mass including suspension is 1.25 times the slider mass (1.59 mg)).J=2.971×10−13kgm2 (effective moment of inertia including suspension is 1.36 times that of the slider only (2.19×10−13kgm2)).ζf=0.02, ζr=0.02, and fc0=0mN.The mass and moment of inertia of the slider are important parameters for determining the slider instability. If the mass and moment of inertia listed in Table 1 are used, the slider does not become unstable.(3) Page 252, left-hand column, line 14 should read: “The air-bearing damping ratio in Eq. (4) is assumed to be 0.02.”
Optimization of reservoir cut-off parameters: a case study in SW Iran (2011)

ABSTRACT Although reservoir quality cut-off criteria have been used for more than 50 years as a guide for economic decisions, there is still no rational procedure for identifying and applying them in Iranian oil and gas fields. In other words, there are different ‘rules-of-thumb’ in different sections of the National Iranian Oil Companies for determination of cut-off values. For instance, in one section, values of 10%, 50% and 50% are used for porosity, water saturation and shale content cut-offs, respectively; in another section, cut-off criteria are not used at all, simply an estimate of the time when 20% of oil-in-place could be produced. This paper addresses the optimization of cut-off value estimation from raw and processed petrophysical data based on extracting the most appropriate relationship for permeability as a function of porosity, water saturation and shale content – k = ƒ( ϕ , S w , V sh ). The procedure starts by looking at permeability as the key parameter in choosing a cut-off value because sometimes the minimum value (the permeability cut-off) is directly related to economic circumstances and is defined by the client. Regression analysis coefficients of 0.936 and 0.870 were achieved for relationships of the form k = ƒ ( ϕ , S w , V sh ) in the two petrofacies intervals studied. This leads to specification of minimum k values of permeability and determination of optimum cut-off values for ϕ , S w and V sh . This method is then used to determine optimum cut-off values for the Burgan Member (sandstone) in the Kazhdumi Formation in an offshore oil field in the Persian Gulf. The calculated cut-off values for this case for k = 1.0 mD are ϕ = 12.5%, S w = 60% and V sh = 27%, as opposed to the ‘standard’ corporate values of ϕ = 10%, S w = 50% and V sh = 50%.
Semantic and psychometric validation of the Brazilian Portuguese version (PASE-P) of the Psoriatic Arthritis Screening and Evaluation questionnaire (2018)

465 patients diagnosed with psoriasis (158 with psoriatic arthritis confirmed by a rheumatologist according to the CASPAR criteria and 307 without) were evaluated in dermatology clinics. We performed the analysis of semantic equivalence in eight steps. For psychometric equivalence, we evaluated the data quality, reliability, construct validity, well-known groups and discriminant characteristics of the items, as well as a ROC curve to determine optimal PASE-P cutoff points in case identification and their sensitivity / specificity. The final version presented excellent reproducibility (CCI = 0.97) and reliability (Cronbach's alpha> 0.9). A cut-off point of 25 distinguished between patients with and without psoriatic arthritis, with sensitivity of 69.5 and specificity of 86.8. PASE-P proved to be culturally valid and reliable to screen for psoriatic arthritis in Brazilian patients with psoriasis.
Technical Notes and Correspondence Remote Control Over Noisy Communication Channels: A (2007)

In this note, we consider a set up in which the plant and con- troller are local to each other, but are together driven by a remote refer- ence signal that is transmitted through a noisy discrete channel. Our goal is to design codeword lengths of block source and channel encoders, and a controller to meet a model matching performance objective. Such design problems are difficult in general, as there is a strong interplay between con- trol objectives and communication constraints, which forces the synthesis of controllers and encoder-decoder pairs to be done simultaneously. Cur- rent approaches typically fix one, while the other is designed to meet some objective. We first construct a model matching performance metric that captures the tradeoffs between coding the reference command to achieve more accuracy at the remote site and designing a controller to meet per- formance. We then simultaneously synthesize the controller and encoder codeword lengths that meet the specified objective for a first-order plant and model case. Finally, we illustrate performance sensitivity to the poles of the plant and model, and to the channel noise.
System-level power optimization of special purpose applications: the Beach Solution (2002)

This paper describes a new approach to low-power bus encoding, called "The Beach Solution", which is thought for power optimization of digital systems containing an embedded processor or a microcontroller executing a special-purpose software routine. The main difference between the proposed method and existing bus encoding techniques is that it is strongly application-dependent, in the sense that it is Based on the analysis of the execution stream of a given program. This allows an accurate computation of the correlations that may exist between blocks of bits in consecutive patterns, and that can be successfully exploited to determine an encoding which minimizes the bus transition activity. Experimental results, obtained on a set of special-purpose applications, are very promising; reductions of the bus activity up to 64.8% (41.9% on average) have been achieved over the original address streams.
Imaging the Transient Boundary Layer on a Free Rotating Disc (2002)

This report presents a visual study of the transition process of the laminar boundary layer (BL) in a turbulent BL on a free rotating disc. The imaging is based on an experimental investigation that aimed to analyze the structure of the BL by relating it to the ratio between turbulent energy and vortex energy, the critical and the transient Reynolds numbers (Re), the vortex numbers and their dependence on Re, and on the distance from the rotating disc.
NC milling error assessment and tool path correction (1994)

A system of algorithms is presented for material removal simulation, dimensional error assessment and automated correction of five-axis numerically controlled (NC) milling tool paths. The methods are based on a spatial partitioning technique which incorporates incremental proximity calculations between milled and design surfaces. Hence, in addition to real-time animated five-axis milling simulation, milling errors are measured and displayed simultaneously. Using intermediate error assessment results, a reduction of intersection volume algorithm is developed to eliminate gouges on the workpiece via tool path correction. Finally, the view dependency typical of previous spatial partitioning-based NC simulation methods is overcome by a contour display technique which generates parallel planar contours to represent the workpiece, thus enabling dynamic viewing transformations without reconstruction of the entire data structure.
Deposition of Thick Silicon Layers Using a Radio-Frequency Thermal Plasma (1998)

Abstract RF Ar-H2 plasma spraying of metallurgical grade silicon particles (80-125 µm) was used in order to combine the purification and the deposition process of silicon particles with a high deposition rate (300 - 600 µm). The hydrogen and oxygen content of the plasma gas turned out to be of a great importance to purify metallurgical silicon powders. The whole process was investigated through ex-situ characterisation of the deposits and on-line diagnostics of the plasma which results matched quite well with the mathematical modelling. The deposits were characterised using SEM, EDX analysis, SIMS, XPS in order to explain the composition and overall properties of the layers in view of their use in photovoltaic applications. Characterisation of silicon deposits was completed by the hydrogen rate analysis using exodiffusion method. Hydrogen trapping in plasma sprayed deposits was found in order of 1019 at/cm3. The oxygen contained in the original powders (30%) was decreased down to 3 - 5% in the deposits. Finally, the on-line diagnostics of the plasma used was : Laser Doppler Anemometry (LDA), Laser Doppler Granulometry (LDG) and Optical Emission Spectroscopy (OES). The mean velocity and surface temperature of particles was found to be in agreement with modelling results.

INTRACELLULAR CYCLIC ADENOSINE 3', 5'-MONOPHOSPHATE AND RELAXING EFFECTS OF ISOPRENALINE AND PAPAVERINE ON SMOOTH MUSCLE OF INTESTINE (1972)

The beta-adrenergic action is thought to be related to the ability of the beta-adrenergic stimulants to increase the intracellular level of cyclic adenosine 3’,5’-monophosphate (cyclic AMP) in the smooth muscle (1). Recently some workers (2,3) have mentioned that papaverine, a smooth muscle relaxant, is found to strongly inhibit cyclic phosphodiesterase in rabbit aorta and rat uterus. On the other hand, Takagi, Takayanagi and Tomiyama (4, 5) have reported that the relaxing effects of papaverine and isoprenaline, a beta-adrenergic stimulant, are identical to exogenous dibutyryl cyclic AMP and that these drugs suppress a supply of calcium to the contractile protein at the membrane, Further, Takagi, Takayanagi and Tsuchida (6) have also indicated using the taenia from the guinea pig caecum that caffeine and imidazole, which influence phosphodiesterase activity, considerably modify the responses of the taenia to isoprenaline and papaverine, while the action of phenylephrine, an alpha-adrenergic stimulant, is slightly affected by caffeine and imidazole. These results indicate the possibilities that the actions of beta-adrenergic stimulants and papaverine are mediated through an increase of the intracellular level of cyclic AMP and that cyclic AMP is not concerned with the response to alpha-adrenergic stimulants.
Comparison of Ring-Liner Oil Film Thickness Resulting from Different Injector Designs in a Diesel Marine Engine Using an Ultrasound Measurement Method (2021)

&lt;div&gt;The global drive to combat climate change is a primary driving force towards producing greener and cleaner marine diesel engines to meet emission legislations. The main cause of an engine’s parasitic frictional loss is the interaction between piston rings and the cylinder liner. Therefore, the piston ring lubricating oil film has been the focus of much prior research, chiefly focusing on small-scale automotive engines. This work employs the ultrasonic reflectometry technique to evaluate the oil film formation resulting from different lubricant injector arrangements on a large two-stroke marine diesel engine. A series of piezoelectric transducers close to the top dead center (TDC) have quantified the oil film thickness (OFT) across three engine loading levels and three injector configurations. The injector configurations compare a more traditional pulse-jet (PJ) injector to a needle lift-type (NLT) injector, which reduces the rate of lubricant atomization. The results gathered show that the OFT increases with decreased engine load for all injector systems. The needle lift injector has been shown to increase the minimum OFT for the first ring at the TDC, reducing the likelihood of boundary lubrication for this ring while also reducing the amount of lubricant present in the exhaust manifold.&lt;/div&gt;
