Type II to type I conversion of pseudomorphic GaAs on InP dependent on growth direction (1989)

Predictions of band offsets assign a type-II offset for the GaAs–InP interface without inclusion of strain effects, with the conduction- and valence-band-edge offsets approximately given by 0.4 and 0.3 eV, respectively. It has been demonstrated recently that pseudomorphic GaAs grown on [100]-oriented InP also has a type-II interface, but with the conduction-band offset reduced by the hydrostatic deformation potential of GaAs. Poisson’s ratio in GaAs for [111]-directed uniaxial stress is smaller by 40% than the value for [100]-directed stress. The lattice constant perpendicular to the growth interface is therefore not reduced as much for [111] growth compared with the [100]-growth case, leading to a consequently larger shift of the conduction-band-edge energy. Based on the recently measured value of −9 eV for the conduction-band-edge hydrostatic deformation potential in GaAs, the band offset for pseudomorphic GaAs grown on (111) InP has been calculated to be type I. This material system should therefore show type II to type I conversion dependent on the growth direction of the pseudomorphic layer. The issues involved in the growth and measurement of GaAs grown on (111) InP are discussed briefly.
Sedation and anesthesia in the cardiac catheterization lab (2015)

I the last decade, procedures in the Cardiac Catheterization lab become more complex, take longer time, and involve higher sick patients. That led to many changes in strategy, and move from the Operating Room to the Cathlab. This originated new challenges to attending physicians and Anesthesiologists particularly. More and more they are managing a large range of children of different ages, different cardiac anomalies (some very complex), requiring an intervention in the cathlab instead or as a supplement to the surgery. No need to say that the Cathlab is a remote location, creating a hostile and unfamiliar environment, that makes the management of these patients more challenging. Therefore, many of these procedures require General Anesthesia instead of Sedation. The Anesthesiology Department must be active in developing protocols and management guidelines. The aims of this lecture will be to: • Describe the different indications for cardiac interventional procedures • Discuss the choice of the anesthesia technique (General Anesthesia versus Sedation) • Explain the notion of sedation and its complications • Decide the level of expertise of the physicians in charge of these cases • Consider safety as an important concern in this special setup
Paradoxical Continuous Left-to-Right Ductal Shunt during Circulatory Collapse due to Ductal Closure in an Infant with Duct-Dependent Systemic Circulation (2022)

Duct-dependent systemic circulation is accompanied by a right-to-left ductal shunt, at least during systole. Although observations of paradoxical continuous left-to-right shunts in duct-dependent systemic circulation have been reported, the mechanism remains unclear. We report a continuous left-to-right ductal shunt throughout the cardiac cycle during the initial recovery phase from circulatory collapse and right ventricular (RV) dysfunction due to ductal closure in an infant with hypoplastic left heart and severe aortic coarctation. Further recovery improved his RV function and changed the ductal flow from continuous left-to-right to bidirectional, which is usually seen in duct-dependent systemic circulation. Marked RV dysfunction may contribute to the continuous left-to-right ductal shunt. A continuous left-to-right ductal shunt should not be used to rule out duct-dependent systemic circulation.

Potential benefits of a Paired Approach procedure to closely spaced parallel runways in instrument and marginal visual conditions (2008)

This paper discusses a concept called ldquopaired approachesrdquo which is designed to facilitate approaches to closely spaced parallel runways (CSPRs) - i.e., runways separated by 700 ft to 2500 ft, in instrument meteorological conditions (IMC). Such runway pairs experience a significant loss of arrival capacity during IMC and marginal visual conditions because currently, runway pairs like this can only be used for simultaneous arrivals when pilots can provide visual separation. The basic procedure design, operations concept, the required cockpit tools and initial feasibility of the paired approach concept were developed in the 1990psilas and included real time pilot and controller simulations and evaluations. These initial simulations indicated that the paired approach procedure was feasible for both pilots and controllers. This paper focuses on the potential benefits of the procedure. It first provides a brief review of the procedure and prior work. It discusses the variety of procedures currently available for parallel runways, and discusses the magnitude of the delay problem in the National Airspace System (NAS) not addressed by any of these existing procedures or procedures under development, but which the proposed paired approach procedure would address. It presents the potential capacity gain from the paired approach procedure at two representative major airports, and the percentage of time that the procedure could be available. The paper also presents a brief summary of potential infrastructure requirements for implementing the procedure, and concludes by providing an outline of the research and development needed to establish its deployment in the NAS.
Minimum Inhibitory Concentration Determinations for Ceftiofur and Spectinomycin against Pasteurella multocida, Mannheimia spp. and Haemophilus somnus from France, The Netherlands, and Germany (2001)

Ceftiofur is an extended-spectrum cephalosporin approved in many countries worldwide for treatment of bovine respiratory disease (BRD), as well as respiratory disease of other animals. Ceftiofur has demonstrated excellent in vitro activity against bacteria of importance in BRD: Mannheimia spp., Pasteurella multocida, andHaemophilus somnus. Spectinomycin is an aminocyclitol antimicrobial agent. Spectinomycin sulfate was recently approved in the United States for treatment of BRD caused by P. multocida, Mannheimia spp., and H. somnus; approvals are currently pending in other countries. To determine the in vitro activity of ceftiofur and spectinomycin against recent BRD pathogens from France, The Netherlands and Germany, minimum inhibitory concentrations (MIC) were determined.

Future directions of dynamically reprogrammable systems (1995)

FPGAs have made it possible to build dynamically reprogrammable systems. This paper reviews the current state of FPGA technology, and discusses the two main classes of dynamically reprogrammable systems: logic emulators and reconfigurable computers. Current practice and future directions for each are explored.
The Development of an Oil-Immersed Surge Arrester for Distribution Transformers (1985)

The recent development of an oil- immersed, zinc oxide surge arrester meets a need for distribution transformer protection that is immune to environmental factors that frequently cause premature failure of conventional external arresters. This paper describes the design philosophy used to determine the requirements for this device and the tests performed to assure that they were satisfactory. Also discussed are benefits that this unique arrester provides in the form of improved reliability and cost effective surge protection of overhead and underground power distribution systems.
A New Technique for the Evaluation of Acid Additive Packages (1992)

Abstract The expanded use of sandstone matrix acidizing techniques may have been the most significant trend of the turbulent 1980's. Gulf Coast operators have found that remedial acid treatments cost a fraction of that required for a comparable offshore completion. Improved design and application techniques now provide economic success rates greater than 80% with most treatments paying out in less than 30 days. However, one area that continues to frustrate designers of acid treatments is the unpredictability of crude oil reservoirs. Current testing procedures are inadequate, failing to accurately replicate the interaction between the treating fluid and acid sensitive crudes. Reliance on these procedures can produce catastrophic facility upsets, downhole emulsion blocks, reduced damage removal efficiency or result in a marginal treatment response. A new simplified laboratory testing procedure was developed which more accurately simulates treatment effects under reservoir conditions. This laboratory test demonstrates the need for less reliance on surfactant non-emulsifiers and an expanded use of mutual solvents. Field data confirms more accurate prediction of add compatibility. In addition, acid treatments designed utilizing this laboratory procedure showed greater initial production response and maintained the incremental increase for a much longer time. Design guidelines are presented which address concerns of mutual solvent/corrosion inhibitor incompatibility, high temperature applications and treating volume requirements.
Effect of delay on culture of urine (1976)

One hundred random urine specimens which were submitted for culture were planted using a calibrated loop within 2 h of collection and 2 and 4 h later after standing at room temperature. Colonies were counted after an 18- to 24-h incubation at 37 degrees C. Fifteen of the specimens demonstrated increases in counts exceeding 1 X log10; four increased from less than 10(5)/ml to greater than 10(5)/ml (three by the 4-h culture and a fourth by the 6-h culture), supporting the concept that delays of greater than 2 h in inoculating cultures may produce results which could cause errors in diagnosis.

Minimalinvasive Leberresektionen haben bei gleichen onkologischen Ergebnissen wie offene Eingriffe eine geringere Morbidität, geringeren Blutverlust und kürzere Krankenhausverweildauer für die Patienten [1], [2], [3]. Mittlerweile sind alle Lebersegmente über einen minimalinvasiven Zugang erreichbar [4]. Auch komplexe und erweiterte Leberresektionen können minimalinvasiv durchgeführt werden.
A Vector Model of Causal Meaning (2019)

This paper proposes a new model of causal meaning, the Vector Model, which formalizes a model of causation based on Talmy’s notions of force dynamics (Wolff, Song, & Driscoll, 2002). In the Vector Model, the concepts of CAUSE, ENABLE and PREVENT are distinguished from one another in terms of force vectors, their resultant and the relationship of each force vector to a target vector. The predictions of the model were tested in two experiments in which participants saw realistic 3D-animations of an inflatable boat moving through a pool of water. The boat’s movements were completely determined by the force vectors entered into a physics simulator. Participants’ linguistic descriptions of the animations were closely matched by those predicted by the model given the same force vectors as those used to produce the animations. Our model may have implications for the semantics of causal verbs as well as the perception of causal events.
Rheo-photoacoustic (RPA) FT-IR spectroscopic studies of the adhesion of thermosets to polyolefins (1999)

Interfacial forces responsible for the adhesion of a coating are influenced by the nature and magnitude of the interactions between the coating and the substrate. When stresses are applied, these interactions may be altered, resulting in potential energy changes within the neighboring layers of macromolecules forming an interfacial region. In this work, rheo-photoacoustic (RPA) Fourier transform infrared (FT-IR) analysis and previously developed theory were utilized in an attempt to correlate molecular-level interactions in polymer bilayer systems under elongational deformations and changes in potential energy, leading to determination of the work of adhesion (WA). This research expands the scope of previous findings and provides a relationship between the C-H stretching vibrational energy changes for acrylic/polyethylene (ACR/PE), epoxy/polyethylene (EP/PE), acrylic/polypropylene (ACR/PP), and epoxy/polypropylene (EP/PP) bilayer systems and the interfacial forces responsible for adhesion. Using the vibrational energies of the C-H stretching bands and their response to the elongational forces imposed at the interface, the WA values were determined for ACR/PE, EP/PE, EP/PP, and ACR/PP. These experiments also indicated that there is a correlation between WA and the glass transition temperature (Tg) of the top coating.
Electronic coupling through natural amino acids (2015)

Myriad scientific domains concern themselves with biological electron transfer (ET) events that span across vast scales of rate and efficiency through a remarkably fine-tuned integration of amino acid (AA) sequences, electronic structure, dynamics, and environment interactions. Within this intricate scheme, many questions persist as to how proteins modulate electron-tunneling properties. To help elucidate these principles, we develop a model set of peptides representing the common α-helix and β-strand motifs including all natural AAs within implicit protein-environment solvation. Using an effective Hamiltonian strategy with density functional theory, we characterize the electronic coupling through these peptides, furthermore considering side-chain dynamics. For both motifs, predictions consistently show that backbone-mediated electronic coupling is distinctly sensitive to AA type (aliphatic, polar, aromatic, negatively charged and positively charged), and to side-chain orientation. The unique properties of these residues may be employed to design activated, deactivated, or switch-like superexchange pathways. Electronic structure calculations and Green's function analyses indicate that localized shifts in the electron density along the peptide play a role in modulating these pathways, and further substantiate the experimentally observed behavior of proline residues as superbridges. The distinct sensitivities of tunneling pathways to sequence and conformation revealed in this electronic coupling database help improve our fundamental understanding of the broad diversity of ET reactivity and provide guiding principles for peptide design.
Machine Learning Quantitation of Cardiovascular and Cerebrovascular Disease: A Systematic Review of Clinical Applications (2021)

Research into machine learning (ML) for clinical vascular analysis, such as those useful for stroke and coronary artery disease, varies greatly between imaging modalities and vascular regions. Limited accessibility to large diverse patient imaging datasets, as well as a lack of transparency in specific methods, are obstacles to further development. This paper reviews the current status of quantitative vascular ML, identifying advantages and disadvantages common to all imaging modalities. Literature from the past 8 years was systematically collected from MEDLINE<sup>®</sup> and Scopus database searches in January 2021. Papers satisfying all search criteria, including a minimum of 50 patients, were further analysed and extracted of relevant data, for a total of 47 publications. Current ML image segmentation, disease risk prediction, and pathology quantitation methods have shown sensitivities and specificities over 70%, compared to expert manual analysis or invasive quantitation. Despite this, inconsistencies in methodology and the reporting of results have prevented inter-model comparison, impeding the identification of approaches with the greatest potential. The clinical potential of this technology has been well demonstrated in Computed Tomography of coronary artery disease, but remains practically limited in other modalities and body regions, particularly due to a lack of routine invasive reference measurements and patient datasets.
Glucocorticoid-binding components in human thymus hyperplasia. (1978)

Preliminary experiments on thymocyte suspensions derived from human thymus hyperplasia indicated the presence of specific cytoplasmic receptors binding [3H]-dexamethasone with high affinity and specificity. The receptor was rapidly transferred into the nuclei at 28 degrees but not at 2 degrees. With cell-free preparations and ion-exchange cellulose-impregnated paper filters, thymus cytosol bound [3H]dexamethasone with a dissociation constant of 4.3 x 10(-9) M; the concentration of receptor sites was 9.6 x 10(-14) mole/mg cytosol protein. Cytosol contained binding components that sedimented at approximately 7S and 3.6S (low ionic strength) and at 4S (high ionic strength). Competition studies showed high specificity for glucocorticoids since binding of labeled dexamethasone was inhibited in the presence of 10(-6) M beta-methasone, prednisolone acetate, dexamethasone, corticosterone, cortisol, and cortisone. 17beta-Estradiol, testosterone, and dihydrotestosterone at 10(-6) M did not inhibit specific binding of [3H]dexamethasone. Thus, the dexamethasone-binding components of the human thymus hyperplasia had properties similar to those described for steroid hormone receptors present in target tissues.
Accountable resource allocation in broadband wireless networks (2010)

Varying channel quality between a user and a base station in cellular and broadband wireless access networks leads to varying channel resource usage per Kbps user throughput. In this paper, we present the position that channel variations that are induced by user activity should be explicitly separated from those induced by network deployment and other factors; the variations should be treated differently during resource allocation by MAC schedulers to be accountable to both users and network operators. For instance, while variations induced by user activity generally warrants proportional or slot-based fairness across users, network-induced variations warrant throughput-based fairness. To enable such customization of fairness metrics on different groups of flows, we propose ARA, a novel accountable resource allocation framework that builds on wireless network virtualization technology. We demonstrate the efficacy of ARA through prototype evaluation on a WiMAX testbed, and present preliminary measurements on categorizing the variations into user-induced and network-induced variations.
Self-reported outcome in new hearing aid users over a 24-week post-fitting period (2004)

Evidence for the existence of auditory acclimatization is mixed, and the implications for clinical practice are unclear. The aim of this study was to seek evidence of perceived changes in performance over a 24-week post-fitting period. Thirty-two new, elderly subjects were recruited and fitted monaurally with the same model of linear, programmable hearing aid that provided in excess of 20-dB insertion gain at 2000-4000 Hz. The Glasgow Hearing Aid Benefit Profile (GHABP) was used to measure self-reported changes over time. The questions concerning benefit and satisfaction were modified to produce two versions: half of the subjects reported changes relative to the time of fitting, while the remainder reported changes relative to the previous occasion on which they completed the GHABP (3 weeks earlier). Subjects reported using hearing aids in excess of 90% of the time when in listening situations that cause difficulty. The median residual disability measure from the GHABP remained low (10-20%) over the duration of the study. The median scores for additional benefit and satisfaction showed a small but statistically significant improvement over the first 3 months of hearing aid use but only for the subjects who referenced this to their perceived performance 3 weeks earlier. The limited evidence for self-reported improvements in benefit and satisfaction over time reported to date must be tempered by the possibility of response bias arising from the method used to measure changes over time.
Theoretical Study of Non-Bonded Interaction between Anticancer Drug Fludara and (2S,3R,4S,5S)-2-(Hydroxymethyl)-3,5-dimethyloxolane-3,4-diol: A DFT Study (2021)

In this research, the density functional theory (DFT) calculations were carried out for investigation non-bonded interaction between the anticancer drug Fludarabine (Fludara) with sugar molecule (2S,3R,4S,5S)-2-(hydroxymethyl)-3,5-dimethyloxolane-3,4-diol (OXO) by using B3LYP/6-311+G* level of theory in the solvent water. The electronic spectra of the Fludara drug and Fludara/OXO complex in solvent water were calculated by time dependent density functional theory (TD-DFT) for the study of intermolecular interaction effect. The non-bonded interaction effects of the Fludara drug with OXO on the electronic properties, natural charges and chemical shift tensors have been also detected. The results display the change in title parameters after interaction process. According to the natural bond orbital (NBO) results, the Fludara molecule and OXO play as both electron donor and acceptor at the Fludara/OXO complex. On the other hand, the charge transfer is occurred between the bonding, antibonding or nonbonding orbitals in two molecules drug and OXO.
Genie in a bottleneck: : How a supply squeeze has worked magic for TiO2 (2017)

As environmental inspections cut Chinese titanium dioxide output and producers elsewhere in the world fail to pick up the slack, prices for the pigment chemical have staged a surprise turnaround, William Clarke, IM Reporter, finds.

The strength of demand for titanium dioxide (TiO2), the white pigment used in a wide range of coatings, paper, plastics and inks, is considered a lagging indicator of global economic strength.

Rising wealth drives higher demand for manufactured goods and fuels construction activity, pushing pigment prices higher.

But TiO2 producers have reported that prices for the chemical, which languished though 2015 and most of 2016, have outpaced global economic growth this year, thanks to a slowdown in Chinese production and some bottlenecks in European supply.

IM's spot price for pigment-grade TiO2 in northern Europe rose to EUR 2,765-3,190/tonne ($3,306-3,815/tonne*) in May, a two-year high, and have held at that level through the summer, when buying traditionally slows to a crawl.
