INTERNATIONAL WORKSHOP ON CARDIOVASCULAR DISEASE: BLOOD PRESSURE MONITORING FROM WOMB TO TOMB (1990)

This paper is intended to illustrate the biostatistical procedures that may be used to construct reference limits for 24-hr patterns of blood pressure (BP). The operational technique is presented with the aim of producing uniform criteria for standardization, in order to facilitate the clinical interpretation of BP monitoring. The methodology is mainly based on the biostatistical methods offered by chronobiology (chronobiometry), the temporal qualification of BP series implying that reference standards are to be time-dependent. The chronobiometric methodology provided genuine advantages for this purpose, allowing us to construct different types of reference standards that can be used appropriately in the clinical management of arterial hypertension. It must be emphasized that standardization is particularly important these days, since practical medicine largely uses BP monitoring without knowing exactly the timequalified limits that refer to the haemodynamic variable in its physiological course. All medical doctors are aware that BP is the variable that has had its normal limits determined on a worldwide scale. The World Health Organisation (WHO), in a famous report dated 1978, gave its standardization approach, including the guidelines for diagnosing deviant BP (WHO, 1978). The pertinent question is 'are the WHO thresholds reliable for interpretating the BP monitoring in its clinical meaning?'. To answer this question, it must be stressed that the WHO standards completely ignore the temporal variability of BP values. The limits are fixed at 140/90 mmHg regardless of the clock hour in which the BP is measured. Such inflexibility is considered unacceptable from a biostatistical and clinical point of view. Biostatistically, it must be remarked that the WHO guidelines were derived from data contributed by different individuals having no apparent relation to each other. This 'spatial sample' only explores the inter-individual variability, forgetting that a vast body of research has invariably demonstrated that BP shows a within-day variability (Kennedy et al., 1983; Littler et al., 1978; Miller-Craig et al., 1978; Pickering et al., 1976). As the changes are time-dependent on a 24-h scale, the reference standards should represent not only the inter-individual but also the intra-individual variability (Fig. 1), each
Cosmological Bounces Induced by a Fermion Condensate (2023)

We show that it is possible for fermion condensation of the Nambu-Jona-Lasinio type to induce a nonsingular bounce that smoothly connects a phase of slow contraction to a phase of expansion. A chiral condensate-a nonzero vacuum expectation value of the spinor bilinear ⟨Ψ[over ¯]Ψ⟩-can form spontaneously after a slow contraction phase smooths and flattens the universe and the Ricci curvature exceeds a critical value. In this approach, a high density of spin-aligned free fermions is not required, which avoids the problem of generating a large anisotropy and initiating chaotic mixmaster behavior during the bounce phase.
Enabling Frequency Reuse for Licensed-Assisted Access with Listen-Before-Talk in Unlicensed Bands (2016)

Licensed-Assisted Access (LAA) which allows LTE to be deployed in unlicensed spectrum is a promising technique currently under standardization in 3GPP Rel-13. To guarantee a peaceful coexistence of LAA with the incumbent systems such as WiFi, listen-before-talk (LBT) which requires the node to sense the medium before data transmission is introduced. On the other hand, LBT also prevents simultaneous transmission from neighbouring nodes of the same LAA operator. In order to increase the spectral efficiency of LAA, frequency reuse for transmission by neighbouring nodes of the same operator has been agreed to be one target of LAA design. In this paper we evaluate the performance of LAA in an indoor scenario assuming both one and two LAA networks deployed by different operators. It is shown that LBT is indeed needed to ensure good performance with multiple LAA operators, especially at high load. And frequency reuse between neighbouring nodes of the same LAA operator can further improve the performance.

Blockchain for Development in the Era of Pandemics (2020)

In the context of Information and Communication Technologies for Development, several efforts have been carried out over the last decades to help developing countries address their challenges. In times of a pandemic, such as the COVID-19 pandemic, several of these challenges gain higher priority in development as they may become unmanageable with the resources of the developing world. Blockchain is a new technology in this area that could potentially be a game-changer and enable the easier and more sustainable addressing of several such challenges. COVID-19 offers a unique opportunity to utilize Blockchain, which is now in its first steps of maturity, and gain hands-on experiences in the development area. This work focuses on understanding the focused area defined by Information and Communication for Development, Blockchain, and the COVID-19 pandemic. Driven by extensive literature analysis, and targeted interviews, new insights are acquired and are critically discussed. The results point out towards areas where Blockchain could be utilized, and while a critical discourse points out the pros and cons in several areas. Several stakeholders are expected to benefit from the results and critical discussions, such as officers in developing countries that consider new technologies to address the challenges of the pandemic, industries that develop solutions and services with Blockchain, scholars that can get new insights for research, policy-makers, and regulators that may deal with initiating new actions or policies, as well non-governmental organizations active in developing countries.
Characterization of InGaN quantum dots grown by metalorganic chemical vapor deposition (2019)

Abstract InGaN quantum dots were grown by metalorganic chemical vapor deposition and shown to exhibit a bimodal size distribution. Atom probe tomography was used to characterize the dots in conjunction with atomic force microscopy, photoluminescence, and x-ray diffraction. Small dots with low indium contents were found to coexist with larger, very high indium composition dots. Significant compositional fluctuations were observed in the small dot population. The dots showed abrupt interfaces with the surrounding GaN, verifying the ability to cap the dots without causing intermixing for even extremely high indium content dots.
Improving Management Performance of P2PSIP for Mobile Sensing in Wireless Overlays (2013)

Future wireless communications are heading towards an all-Internet Protocol (all-IP) design, and will rely on the Session Initiation Protocol (SIP) to manage services, such as voice over IP (VoIP). The centralized architecture of traditional SIP has numerous disadvantages for mobile ad hoc services that may be possibly overcome by advanced peer-to-peer (P2P) technologies initially developed for the Internet. In the context of mobile sensing, P2PSIP protocols facilitate decentralized and fast communications with sensor-enabled terminals. Nevertheless, in order to make P2PSIP protocols feasible in mobile sensing networks, it is necessary to minimize overhead transmissions for signaling purposes, which reduces the battery lifetime. In this paper, we present a solution to improve the management of wireless overlay networks by defining an adaptive algorithm for the calculation of refresh time. The main advantage of the proposed algorithm is that it takes into account new parameters, such as the delay between nodes, and provides satisfactory performance and reliability levels at a much lower management overhead than previous approaches. The proposed solution can be applied to many structured P2P overlays or P2PSIP protocols. We evaluate it with Kademlia-based distributed hash tables (DHT) and dSIP.
Anesthetic Experience With Endovascular Aortic Aneurysm Repair (2010)

Background: We endeavored to characterize the anesthesia experience with endovascular aneurysm repair (EVAR) at a large academic medical center in the United States. Methods: A retrospective review of electronic medical records was conducted for all patients undergoing elective EVAR from 2002 to 2007 in a large academic medical center. Results: A total of 522 cases met inclusion criteria, with 4% of cases using general anesthesia (GA), 92% regional anesthesia (RA), and 4% local anesthesia (LA). There was no statistically significant difference between the groups for duration of surgery or in-hospital mortality. In-hospital length of stay was longer for GA than LA or RA. Four cases were converted to open repair. Two mortalities occurred during the perioperative period (0.4% of cases). Conclusions: The vast majority of EVAR were successfully performed under RA, involved mild blood loss, involved infrequent need for conversion to GA, and resulted in brief in-hospital length of stay and low mortality rate.
Influence of magnetic domain size on dipolar interactions and hysteresis field asymmetry in layered high/low coercivity perpendicular anisotropy systems (2014)

Dipolar interactions in low-coercivity/Pd/high-coercivity [Co/Pd]X/Pd/[Co/Pd]10 multilayer systems are studied as a function of the domain size in the [Co/Pd]X low-coercivity layer (LCL), while maintaining the domain size in the high-coercivity layer (HCL) constant. As the number of repeats X increases from 5 to 30, the mean domain size of the [Co/Pd]X LCL decreases from hundreds of micron to hundreds of nanometers. After demagnetization, different regimes can be distinguished from partial or exact domain duplication for LCL domain size larger than HCL one to uncorrelated behavior for much smaller LCL domains. The results obtained via magnetic force microscopy allow understanding the symmetry and asymmetry versus externally applied field as observed in macroscopic magnetometry measurements.

Einleitung: TAp63α ist ein wichtiges Gen für Entwicklung und Differenzierung. Die strukturelle Homologie zu den beiden anderen p53-Familienmitgliedern p53 und p73 legt die Vermutung nahe, dass p63 auch eine bedeutende Rolle in der Apoptoseinduktion spielt.
X-RAY COMPUTED TOMOGRAPHY FOR EMERGING AEROSPACE MATERIALS AND PROCESSES DEVELOPMENT (1993)

The development and qualification of new materials and processes requires characterization of the product as a function of manufacturing and operational parameters. X-ray computed tomography (CT) provides quantitative measurements of material characteristics in terms of the dimensions, density and composition. The results of studies involving CT testing of various materials demonstrate the ability of CT to provide valuable information for material process understanding and characterization. The cost benefit of CT is found in the reduction of risk and schedule savings by reducing cycle time in process development steps. CT is a tool which increases new design options by allowing internal measurement and evaluation at previously inaccessible locations in complex structures. X-ray CT will be a critical tool for organizations competing in emerging materials and processes development.
T1 mapping: Methods and challenges (2011)

Purpose: In this educational abstract, we provide an overview of the main T1 mapping methods and we outline the challenges in performing quantitative T1 measurement. We describe the gold standard (Inversion Recovery), as well as two widely used alternative methods (Look-Locker and Variable Flip Angle) that speed up the scanning and fitting procedures at the expense of accuracy and precision. The e-poster will include sample T1 maps of phantoms and in-vivo human brains acquired with each of the above methods, and it will provide a list of useful T1 mapping references.
Comparative assessment of processes for the transportation of thermal energy over long distances (2012)

This papers deals with the transportation of thermal energy over long distances that could allow the recovery of waste heat from industrial sites. Processes involving thermochemical transformations can be relevant for such purpose as they involve the transportation of a reactive fluid at ambient temperature, and thus allow large distances between source and users. This paper aims to evaluate the performances of all the systems devoted to the transportation of energy, including classical processes (involving electricity, coolant, slurry). A general method has been developed to assess the performances of all the paths of energy transportation. The aim is to analyze the relevance of each process on the same basis. The exergy destruction in each part of these systems is analyzed and the exergy yields are compared
Season affects body composition and estimation of fluid overload in haemodialysis patients: variations in body composition; a survey from the European MONDO database (2014)

BC and hydration state, assessed by bio-impedance spectroscopy, follows a seasonal pattern which may be of relevance for the estimation of target weight, and for the interpretation of longitudinal studies including estimates of BC. Whether these changes should lead to therapeutic interventions could be the focus of future studies.
Dynamic blanking control of single column multi-electron-beam system (2008)

Dynamic individual beam control in a multi-electron-beam system was demonstrated. In a multi-beam system, individual beam blanking and accurate correction of each beam position and irradiation dose are essential. In this paper, 16 beams in a 1024-beam system were individually blanked at 100-MHz frequency. Individual beam blanking was verified by pattern delineation. The beam position was corrected by the data shift through the feedback from the positions of formerly delineated patterns. The irradiation dose was corrected by measuring the dose of each beam and calibrating the irradiation time. Moreover, a movable blanking aperture was installed to improve the uniformity of blanking control. Finally, these corrections were evaluated by measuring the line widths in delineated patterns smaller than 65 nm. As a result, positioning accuracy within 1 pixel and dose deviation within 2.4% were achieved. In conclusion, it was clarified that our multi-beam-system has potential applications in
NIÑOS EXPÓSITOS y AMAS DE CRÍA. LAS AMAS COMO UN FRACASADO SISTEMA DE SUPERVIVENCIA DE LOS NIÑOS EXPÓSITOS (S.XVIII) (2001)

Wet nurses were women who, in exchange for payment, breast-fed babies of other women who could not or would not suckle their own children. These lines focus on the deprived social background of the wet nurses who were employed by foundling hospitals in XVIII-century Spain. The survival of children admitted into these hospitals depended directly on these women, regardless of their capacity for this work. Through an examination of works of essayists of the day, we show the failure of wet-nursing in the survival of these babies.
Replicated arrays of hybrid elements for application in a low-cost micro-spectrometer array (2000)

Abstract We report on the fabrication and characterization of replicated hybrid elements for low-cost micro-spectrometer array applications. An array of hybrid elements, where one surface combines the fairly large dimensions of refractive microlenses with the submicron features of a diffraction grating, was successfully replicated by hot embossing. The parameters are: lens diameter=990 μm, height=60 μm, grating period=1 μm, linewidth=300 nm and grating depth=2 μm. These replicated spectrometer elements showed a maximum resolution of 2.25 nm and a stray-light suppression better than 30 dB.

A low-noise high-power source incorporating a polarization-maintaining erbium-Brillouin fiber amplifier is presented. The output noise power is analyzed and a theoretical noise spectral density is determined. Shot-noise-limited performance is predicted and experimentally achieved within the 1-8-GHz-offset frequency range. The polarization extinction ratio was measured as 25 dB.
Tumour‐selective antivascular effects of the novel anti‐mitotic compound A‐318315: Anin vivorat regional haemodynamic study (2010)

1. It has been shown that tubulin-binding agents can destabilize cellular microtubules and suppress tumour growth; but it has also become apparent that some compounds can exert anti-vascular effects within the neovasculature of a solid tumour. To date, the difficulty with these targets has been the ability to selectivity induce vascular damage to the tumour while leaving normal vasculature unaffected. The data presented here characterizes the in vivo, tumour selective, anti-vascular effects of the novel tubulin-binding agent A-318315. 2. To that purpose, we have used an anaesthetized in vivo rat model designed to quantify acute changes in regional vascular resistance (VR) in both tumour and non-tumour vascular beds, simultaneously. Tissue-isolated tumours (approximately 1.25 gm) with blood flow supplied by a single epigastric artery were grown in the hindlimb of adult male rats. Blood flow to the tumour, mesenteric, renal and normal (non-tumour epigastric) arteries was measured pre-dose and post-dose under anaesthesia. 3. A-318315 was tested at 3, 10 and 30 mg/kg, i.v. These doses produced modest, transient increases in mean arterial pressure with little to no effect on heart rate. At peak effect, tumour VR increased to 175 +/- 47, 337 +/- 77 and 751 +/- 151% above the baseline, for the 3, 10 and 30 mg/kg doses, respectively, whereas VR was only modestly and transiently increased in normal epigastric (88 +/- 19%), mesenteric (33 +/- 3.3%) and renal arteries (17 +/- 8.6%). 4. These data demonstrate that A-318315 produces marked reductions in tumour blood flow in the rat at doses that exert minor effects on normal vascular function.
Synthesis, Photochromic, and Electrical Properties of Diarylethene Derivatives Having 9-Carbazolyl or 2-(1,3,4-Oxadiazolyl) Group as Carrier Mobilization Sites (2011)

Abstract Diarylethene derivatives, 1c and 1d, having carrier mobilization sites have been synthesized. Their photochromic properties are examined both in solution and in thin film. Current–voltage characteristics at photostationary state of 1c and 1d showed drastic current increase compared with the corresponding open-ring isomers 1c and 1d, respectively.
Bioefficacy of crude extracts of Aglaia species (Meliaceae) and some active fractions against lepidopteran larvae (1997)

Abstract Foliar and twig extracts of three species of Aglaia were screened for larval growth inhibiting and antifeedant effects against the polyphagous lepidopteran larvae of Spodopteva litura and Helicoverpa armigera. A. elaeagnoidea and A. odorata crude ethanolic extracts were at par in their activity at an initial treatment level of 5 mg/g of dry diet weight, while A. roxburghiana was half as active as the other two species. Detailed investigation of A. elaeagnoidea species revealed the presence of complex limonoid fractions responsible for this activity. The nutritional analyses showed impaired diet consumption and dietary utilization at 200 ppm level of treatment when limonoid fractions Fr 2 J and Fr 6 K were provided orally to S. litura larvae, indicating centrally mediated anorexic effect. The isolation of the limonoid complex from A. elaeagnoidea should provide useful starting point for the development of a botanical anti‐insect preparation.
Print Culture Histories Beyond the Metropolis (2016)

Bringing together leading scholars of literature, history, library studies, and communications, Print Culture Histories Beyond the Metropolis rejects the idea that print culture necessarily spreads outwards from capitals and cosmopolitan cities and focuses attention to how the residents of smaller cities, provincial districts, rural settings, and colonial outposts have produced, disseminated, and read print materials.Too often print media has been represented as an engine of metropolitan modernity. Rather than being the passive recipients of print culture generated in city centres, the inhabitants of provinces and colonies have acted independently, as jobbing printers in provincial Britain, black newspaper proprietors in the West Indies, and library patrons in "Middletown," Indiana, to mention a few examples. This important new book gives us a sophisticated account of how printed materials circulated, a more precise sense of their impact, and a fuller of understanding of how local contexts shaped reading experiences
