Anomalous Strength Characteristics of Tilt Grain Boundaries in Graphene (2010)

Graphene in its pristine form is one of the strongest materials tested, but defects influence its strength. Using atomistic calculations, we find that, counter to standard reasoning, graphene sheets with large-angle tilt boundaries that have a high density of defects are as strong as the pristine material and, unexpectedly, are much stronger than those with low-angle boundaries having fewer defects. We show that this trend is not explained by continuum fracture models but can be understood by considering the critical bonds in the strained seven-membered carbon rings that lead to failure; the large-angle boundaries are stronger because they are able to better accommodate these strained rings. Our results provide guidelines for designing growth methods to obtain sheets with strengths close to that of pristine graphene.
An interpretation of the Cover and Leung capacity region for the MAC with feedback through stochastic control (2012)

We consider the problem of communication over a multiple access channel (MAC) with noiseless feedback. A single-letter characterization of the capacity of this channel is not currently known in general. We formulate the MAC with feedback capacity problem as a stochastic control problem for a special class of channels for which the capacity is known to be the single-letter expression given by Cover and Leung. This approach has been recently successful in finding channel capacity for point-to-point channels with noiseless feedback but has not yet been fruitful in the study of multi-user communication systems. Our interpretation provides an understanding of the role of auxiliary random variables and can also hint at on-line capacity-achieving transmission schemes.
Study of optical, thermal and radio frequency properties of low emissivity coatings with frequency selective surfaces (2021)

Abstract The use of frequency selective surfaces (FSSs) defined on railcar windows with a metallic low-e coating to improve the reception of mobile communications signals is becoming ever more common. The proximity of the glass to the passenger in this scenario has introduced a new parameter to consider, aesthetics. This paper presents a complete study of the development of a FSS defined by laser ablation, considering all current requirements. The fabricated samples will be characterized in the optical and radiofrequency ranges of the spectrum. Also, by means of an electron microscope, the chemical elements of each area of the samples will be quantified, in order to study the ablation process. New samples will be made using these parameters, and its performance according to specifications verified. These data will be correlated, using digital image processing, to the aesthetic impact of the engraved FSS, as confirmation of the optimal laser configuration.
Association of adipokines with hepatic steatosis and fibrosis in chronic hepatitis B patients on long‐term nucleoside analogue (2019)

Low FGF-21 and high AFABP levels were associated with advanced fibrosis/cirrhosis in CHB patients on antiviral treatment. Plasma AFABP, together with other metabolic risk factors, may aid identification of patients lacking fibrosis improvement during antiviral treatment.
CW Lasing at 1.35 $\mu$m From Ten InAs–Sb : GaAs Quantum-Dot Layers Grown by Metal–Organic Chemical Vapor Deposition (2008)

We report the fabrication of GaAs-based quantum-dot (QD) lasers grown by metal-organic chemical vapor deposition (MOCVD) above 1.3 m. We fabricated a laser diode with ten stacked InAs-Sb:GaAs(100) QD layers, grown by antimony-surfactant-mediated growth. Ground-state lasing was obtained under continuous-wave operation at room temperature at 1.35 mum, with a maximum ground state modal gain of 19.3 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> . These values are the highest values reported for MOCVD-grown GaAs-based QD laser.
Perils of quinolone exposure in cancer patients (2010)

Breakthrough infections were more common in neutropenic patients and in patients who had hematologic malignancies. The isolation of MDR organisms was associated strongly with the use of fluoroquinolones. The current findings demonstrated the importance of using a comprehensive approach to the prevention of MDR bacterial infections, including the initiation of antibiotic stewardship programs.
Time-Aware Authority Ranking (2005)

The link structure of the web is analyzed to measure the authority of pages, which can be taken into account for ranking query results. Due to the enormous dynamics of the web, with millions of pages created, updated, deleted, and linked to every day, temporal aspects of web pages and links are crucial factors for their evaluation. Users are interested in important pages (i.e., pages with high authority score) but are equally interested in the recency of information. Time—and thus the freshness of web content and link structure—emanates as a factor that should be taken into account in link analysis when computing the importance of a page. So far only minor effort has been spent on the integration of temporal aspects into link-analysis techniques. In this paper we introduce T-Rank Light and T-Rank, two link-analysis approaches that take into account the temporal aspects freshness (i.e., timestamps of most recent updates) and activity (i.e., update rates) of pages and links. Experimental results show that T-Rank Light and T-Rank can produce better rankings of web pages.
Experimental Measurements of Ingestion Through Turbine Rim Seals: Part 5 — Fluid Dynamics of Wheel-Space (2013)

This paper discusses the flow structure in typical rotor-stator systems with ingress and egress. Measurements of concentration, velocity and pressure were made using a rotating-disc rig which experimentally simulated hot gas ingestion into the wheel-space of an axial turbine stage. Externally-induced ingress through rim seals was generated from the non-axisymmetric pressures produced by the flow over the vanes and blades in the external annulus. Measurements were conducted using several single- and double-seal geometries and for a range of sealing flow rates and rotational speeds. The concentration measurements showed that the amount of ingress, which increased with decreasing sealing flow rate, depended on the seal geometry. The swirl velocity in the fluid core increased with decreasing sealing-flow rate but, outside the outer region in the wheel-space, it was largely unaffected by the seal geometry or by the amount of ingress. The radial distribution of static pressure, calculated from the measured swirl velocity in the core, was in good agreement with the pressures measured on the stator. The data for the double seals demonstrated that the ingested gas was predominately confined to the region between the seals near the periphery of the wheel-space; in the inner wheel-space, the effectiveness is shown to be significantly higher.
Long-term changes in myosin heavy chain composition after botulinum toxin a injection into rat medial rectus muscle. (2001)

These long-lasting changes in Botx A-paralyzed ocular MR muscles most probably reflect their inability to regain their unique functional characteristics after new motor end plate formation and recovery of muscle contraction.
Effect of van der Waals Interactions on Quantum Phase Transitions and Resulting Phonon Properties of 2H-TaSe$_{2}$ (2020)

Metallic transition metal dichalcogenides like tantalum diselenide (TaSe$_{2}$) exhibit exciting behaviors at low temperatures including the emergence of charge density wave (CDW) states. In this work, density functional theory (DFT) is used to classify the effects and influences of van der Waals interactions, most strongly present between the layers of bulk TaSe$_{2}$ and reduced in monolayer TaSe$_{2}$, on the CDW atomic structures and resulting phonon properties of those structures. Additional support is provided by experimental phonons seen in Raman spectra as a function of temperature and layer number. A variety of modes are described across several spectral regions and matched to corresponding predicted vibrations, including an experimentally observed forbidden mode. These results highlight the importance of understanding interlayer interactions, which are pervasive in many quantum phenomena involving two-dimensional confinement.
La vulnérabilité psychologique des enfants de migrants : étude de la population d'un centre médico-psychologique infantile (2015)

Migration and population displacement are accelerating and psychiatric care of children of migrants are affected today by a burning issue that reveals this reality. The first part of this work includes the work of MR Moro and colleagues about the specific psychological vulnerability of migrant children; the second part discusses the impact that migration can have on parents and family transmission issues, with particular attention to traumatic migration routes and the assumption of psychic intergenerational transmission of trauma; the third part presents the descriptive study of the population of a Bordeaux infant mental health center in order to compare the levels of prevalence of various mental and behavioral disorders in children of migrants, children themselves and non-migrant children. The assumption was based on clinical observation of a particular vulnerability of these children about the post-traumatic stress disorder and internalized disorders in general, and was confirmed. These results should be interpreted taking into account other factors (socioeconomic level, individual and family factors), however they support the existence of "transcultural risk" described by Moro, which are exposed migrant children whose psychopathological mechanisms are not fully known. The terms of child care and family support seem to have to be considered in a cross-cultural perspective to support them in the necessary articulation of worlds and cultures in which they grow up.
Versatile Synthesis of Quinoline-3-Carboxylic Esters and Indol-2-Acetic Esters by Palladium-Catalyzed Carbonylation of 1-(2-Aminoaryl)-2-Yn-1-Ols (2008)

1-(2-Aminoaryl)-2-yn-1-ols, easily obtained by the Grignard reaction between 1-(2-aminoaryl)ketones and alkynylmagnesium bromides, were subjected to carbonylative conditions in the presence of the PdI2-KI catalytic system, in the presence and in the absence of an external oxidant. Under oxidative conditions (80 atm of a 4:1 mixture of CO-air, in MeOH as the solvent at 100 degrees C and in the presence of 2 mol % of PdI2 and 20 mol % of KI), 1-(2-aminoaryl)-2-yn-1-ols bearing a primary amino group were selectively converted into quinoline-3-carboxylic esters in fair to good yields [45-70%, based on starting 1-(2-aminoaryl)ketones], ensuing from 6-endo-dig cyclization followed by dehydration and oxidative methoxycarbonylation. On the other hand, indol-2-acetic esters, deriving from 5-exo-dig cyclization followed by dehydrating methoxycarbonylation, were selectively obtained in moderate to good yields [42-88%, based on starting 1-(2-aminoaryl)ketones] under nonoxidative conditions (90 atm of CO, in MeOH as the solvent at 100 degrees C and in the presence of 2 mol % of PdI2 and 20 mol % of KI), in the case of 1-(2-aminoaryl)-2-yn-1-ols bearing either a primary or secondary amino group and substituted with a bulky group on the triple bond.
THE EFFECT OF EARTHING ON HUMAN PHYSIOLOGY (2007)

The human hody evolved while living in direct electrical contact (electricallv grounded) with the earth. The question that arises is: Does loss of electrical contact with the earth affect human physiology? This douhk-hlind swdy was designed to address this question hy measuring several electrophysiological parameters of the hody. Suhjects were assigned [0 an experimental group that was grounded to the earth after a 28-minure haseline recording. Grounding the hody (earthing) was achieved hy placing electrode patches on the soles of the feet and connecting them to a conductive cahle that was attached to a metal rod planted in the earth. The total recording time was ')6 minutes. The control group was not grounded hur sham grounded. Part 1 of this stud~· presented results from measurements taken with clinical hiofeedhack equipment. This paper pf(:sents results ohtained on Jing-Well points using the SSVP (Single Square Voltage Pulse) method. With the SSVP method we were able to corroborate results presented in our first paper with the biofeedback system. The SSVP method results are that grounding the body produces a reduction in tension (relaxation) of the internal organs and a reduction in inflammation. \X' e also postulated that the body was developed to take advanrage of (he contact with the eanh through the feet hy developing a system of distribution of electrons through the kidney meridian at K11. The presenr finding, are consistent with the results of our previous study which concluded that grounded subjects experienced a reduction in stress and a normalization of the functioning of the auronomic nervous system after eanhing. 6
High Resolution Infrared Spectra of the ν2 and 2ν1 Bands of 14N16O2 (1975)

The infrared spectra of two B type bands, ν 2 and 2ν 1 , of 14 N 16 O 2 have been recorded under high resolution. Ground state combination differences from these bands have been combined with combination differences obtained in previous studies and eight pure rotational microwave transitions to yield improved ground state rotational constants. Upper state constants and band centers for the ν 2 and 2ν 1 bands are also reported. The 2ν 1 band contains internal intensity anomalies believed to arise from a weak Coriolis interaction with the much stronger ν 1 + ν 3 band. Equilibrium rotational constants have been calculated. The equilibrium structure of the molecule is: r c = 1.1945 ± 0.0005 Å and Θ c = 133.85 ± 0.10°. For the sake of comparison, effective, substitution, and average structures are also reported.
Coordination of behavioral hierarchies during environmental transitions inCaenorhabditis elegans (2012)

For animals inhabiting multiple environments, the ability to select appropriate behaviors is crucial as their adaptability is often context dependent. <i>Caenorhabditis elegans</i> uses distinct gaits to move on land and in water. Gait transitions can potentially coordinate behaviors associated with distinct environments. We investigated whether land and water differentially affect the behavioral repertoire of <i>C. elegans</i>. Swimming worms interrupted foraging, feeding, egg-laying and defecation. Exogenous dopamine induced bouts of these land-associated behaviors in water. Our finding that worms do not drink fluid while immersed may explain why higher drug doses are required in water than on land to elicit the same effects. <i>C. elegans</i> is a valid model to study behavioral hierarchies and how environmental pressures alter their balance.

Multicellular Vascularized Engineered Tissues through User‐Programmable Biomaterial Photodegradation (2017)

A photodegradable material-based approach to generate endothelialized 3D vascular networks within cell-laden hydrogel biomaterials is introduced. Exploiting multiphoton lithography, microchannel networks spanning nearly all size scales of native human vasculature are readily generated with unprecedented user-defined 4D control. Intraluminal channel architectures of synthetic vessels are fully customizable, providing new opportunities for next-generation microfluidics and directed cell function.
Information and communication technology (ICT) literacy: Integration and assessment in higher education (2007)

Despite coming of age with the Internet and other technology, many college students lack the information and communication technology (ICT) literacy skills—locating, evaluating, and communicating information—necessary to navigate and use the overabundance of information available today. This paper presents a study of the validity of a simulations-based assessment of ICT literacy skills. Our overall goals for the assessment are to support ICT literacy instructional initiatives at colleges and universities.

Estimation of the Center of Simulated Planetary Bodies (1960)

The task of centering the simulated image of a planetary body on a display representing the viewscreen of a satellite was investigated in a study employing both male and female subjects. It was found that task performance, as measured by relative radial error, is significantly poorer for crescent and gibbous bodies than for full-phase bodies, and that a circular screen is significantly better than a rectangular one. No significant difference appears for the three diameters of planetary image which were tested. There occur large differences among individuals within the subject group, and the male group exhibits lower error scores than the female. The best subject performed at a level of approximately 1 per cent estimation for all conditions. This amount of operator error is theoretically compatible with the requirements for attitude control during the re-entry of a satellite vehicle.
Enterprise Transformation Through Mobile ICT: a Framework and Case Study in Healthcare (2012)

This study examines the transformative value and impact of mobile information and communication technology (ICT) in enterprises. Based on a comprehensive field study of mobile ICT adoption, implementation, and use in enterprises across multiple industries, a multi-stage framework for mobile ICT-enabled transformation was developed. The study revealed that mobile ICT enterprise value consists of increased convenience, higher levels of efficiency, new core competences, and creation of competitive advantage. The organizational impact is realized in existing and newly created data and processes, business models and strategies, and entire markets and industries. Four distinct stages of transformation are identified and described, namely mobilization, enhancement, reshapement, and redefinition. The framework is applied in the context of healthcare. The study contributes to the theoretical understanding of enterprise transformation and IT-enabled change and provides important guidelines for management of emerging technologies.
Temperature-tunable Fano resonance induced by strong coupling between Weyl fermions and phonons in TaAs (2017)

Strong coupling between discrete phonon and continuous electron-hole pair excitations can induce a pronounced asymmetry in the phonon line shape, known as the Fano resonance. This effect has been observed in various systems. Here we reveal explicit evidence for strong coupling between an infrared-active phonon and electronic transitions near the Weyl points through the observation of a Fano resonance in the Weyl semimetal TaAs. The resulting asymmetry in the phonon line shape, conspicuous at low temperatures, diminishes continuously with increasing temperature. This behaviour originates from the suppression of electronic transitions near the Weyl points due to the decreasing occupation of electronic states below the Fermi level (E<sub>F</sub>) with increasing temperature, as well as Pauli blocking caused by thermally excited electrons above E<sub>F</sub>. Our findings not only elucidate the mechanism governing the tunable Fano resonance but also open a route for exploring exotic physical phenomena through phonon properties in Weyl semimetals.
The Xylosyltransferase I Gene Polymorphism c.343G&gt;T (p.A125S) Is a Risk Factor for Diabetic Nephropathy in Type 1 Diabetes (2006)

The XYLT-I c.343G>T polymorphism contributes to the genetic susceptibility to development of diabetic nephropathy in type 1 diabetic patients.
Optimal Design for Crash Characteristics of Cylindrical Thin-Walled Structure Using Origami Engineering (2010)

During car frontal crash, crash energy is absorbed by the parts of front bumper, front side member, front panel member and so on. Previous research has indicated that front side member plays major role in energy absorption. For protecting the passengers, the front side member is expected to absorb crash energy as much as possible. In this study, we adopt cylindrical thin-walled structure using origami engineering as front side member instead of structure with box-shaped cross section which is generally used. We develop an optimization system of the cylindrical thin-walled structure using origami engineering, in which the objective function is to maximize the energy absorption of origami structure; the design variables are structural parameter, number of divisional sections along axis, number of edges of polygonal cross section and number of subdivision levels; the mass and initial peak load of optimal structure must be less than those of structure with box-shaped cross section. We then discuss the optimization results that the optimal structure is capable of absorbing energy 91% more than that of original box-shaped cross sectional structure which is usually bended on the way of being crashed, 37% more than that of original structure which is ideally crashed to bottom without bending.
In Vivo Antibacterial Activity of Acetazolamide (2021)

Vancomycin-resistant enterococci (VRE) represent a major public health threat that requires the development of new therapeutics. In the present study, acetazolamide (AZM) was evaluated against enterococci. It inhibited different enterococcal strains tested at clinically achievable concentrations. Moreover, AZM outperformed linezolid, the drug of choice for VRE infections, in two <i>in vivo</i> VRE mouse models-murine colonization-reduction and VRE septicemia. Collectively, these results indicate that AZM warrants consideration as a promising treatment option for VRE infections.
Polarized Release of Matrix Metalloproteinase-2 and -9 from Cultured Human Placental Syncytiotrophoblasts1 (2000)

The large increase in placental surface area and fetal villous vascular development in the third trimester of pregnancy requires degradation and reformation of the placental basal lamina. Degradation is carried out by matrix metalloproteinases (MMPs) secreted by adjacent cells. Although the gelatinases, MMP-2 and MMP-9, which are released by extravillous cytotrophoblasts (CTs) are believed to play crucial roles in early placental expansion, neither has been reported in third trimester villous trophoblasts nor has appropriate (basolateral) release of any MMP by the highly polarized syncytiotrophoblast (ST) been demonstrated. We demonstrated villous trophoblast expression of both MMP-2 and MMP-9 by in situ immunohistochemistry and by Western blot analysis and zymography of lysates and culture supernatants of highly purified villous CTs. We also found that epidermal growth factor (EGF)-stimulated CT differentiation into ST and stimulation by the phorbol diester, PMA, both increase MMP-9 secretion. The direction of MMP release was determined with confluent cultures of ST on porous membranes. We found that >90% of MMP-2 and MMP-9 were released from the basolateral surface. We conclude that villous STs express and release gelatinases from their basolateral surfaces in a regulated manner and suggest that such polarized release may be important to villous tissue remodeling.
