Applications of multiscale waves concept iterative procedure (2007)

In this paper a multi-scale approach to design planar antennas and circuits is used in the scope of wave concept iterative procedure (W.C.I.P.). This wave formulation is improved for a full modeling of large-scale structures where connections are made through subdomains (layers) in the spectral domain. In the case of circuits integration the usually used elements - via holes and air bridge - are connections introduced to ease their integration in a circuit geometry between two and three dimensions, commonly named 2.5-D. A particular model is used to treat the electromagnetic behavior of these elements. For example, via-holes are treated with the longitudinal components, while air bridge are notably simplified by the introduction of "magnetic carpet". The simulation results presented are in accordance with the electromagnetic theoretical behavior of these connections.

Atomic spectrometry updates. Review of advances in elemental speciation (2014)

This is the sixth Atomic Spectrometry Update (ASU) to focus specifically on advances in elemental speciation and covers a period of approximately 12 months from December 2012. This review deals with all aspects of the analytical speciation methods developed for: the determination of oxidation states; organometallic compounds; coordination compounds; metal and heteroatom-containing biomolecules, including metalloproteins, proteins, peptides and amino acids; and the use of metal-tagging to facilitate detection via atomic spectrometry. The review does not specifically deal with fractionation, sometimes termed operationally defined speciation. As with all ASU reviews1–5 the coverage of the topic is confined to those methods that incorporate atomic spectrometry as the measurement technique. However, molecular MS techniques are covered where the use is in parallel or series with atomic spectrometry. As with previous years As and Se speciation continues to dominate current literature. However, research is moving further towards understanding the toxicological and beneficial mechanisms of these two elements. There is also in increase in macromolecular analysis, with a decrease in detection limits for some methodologies, which increases the potential clinical use of the techniques employed. The use of both atomic and molecular spectrometry is well developed in these fields, highlighting the interdisciplinary nature of today's research environment. The trend towards lower cost more rapid analytical methods, often involving non-chromatographic speciation, also continues apace.

Influence of a Myocardial Infarction on Blood Pressure and Serum Cholesterol (1979)

ABSTRACT Blood pressure (BP) was measured before and after acute myocardial infarction (MI) in 21 men aged 49–60 years from a random population sample. Men on drugs affecting BP before MI or during follow‐up were excluded. Pre‐ and postinfarction cholesterol levels were analyzed in 49 men not on hyperlipidemic treatment recruited from the same population sample. The mean fall in systolic BP (SBP) was 14 mmHg both five weeks and one year after the acute event, but 10 mmHg after two years. The mean fall in diastolic BP (DBP) was 10 mmHg five weeks after the MI and remained at this level for two years. The decreases in SBP and DBP were significant. There was a positive correlation between the maximum rise in SGOT during the acute phase of MI and the decrease in DBP between preinfarction readings and readings five weeks after the MI. Serum cholesterol was unchanged three months, and one and two years after the MI as compared to the preinfarction level.
Somatostatin and insulin mediate glucose-inhibited glucagon secretion in the pancreatic α-cell by lowering cAMP (2014)

The dysregulation of glucose-inhibited glucagon secretion from the pancreatic islet α-cell is a critical component of diabetes pathology and metabolic disease. We show a previously uncharacterized [Ca(2+)]i-independent mechanism of glucagon suppression in human and murine pancreatic islets whereby cAMP and PKA signaling are decreased. This decrease is driven by the combination of somatostatin, which inhibits adenylyl cyclase production of cAMP via the Gαi subunit of the SSTR2, and insulin, which acts via its receptor to activate phosphodiesterase 3B and degrade cytosolic cAMP. Our data indicate that both somatostatin and insulin signaling are required to suppress cAMP/PKA and glucagon secretion from both human and murine α-cells, and the combination of these two signaling mechanisms is sufficient to reduce glucagon secretion from isolated α-cells as well as islets. Thus, we conclude that somatostatin and insulin together are critical paracrine mediators of glucose-inhibited glucagon secretion and function by lowering cAMP/PKA signaling with increasing glucose.
Transaction adaption in system on mobile devices (SyD): techniques and languages (2003)

Resource constraints in wireless environment pose a great challenge to conventional transaction processing techniques. Current transaction processing schemes have limited flexibility, and cannot easily respond and adapt to the changes of runtime environment. In previous work, we proposed a QoS-aware transaction processing framework which supports graceful adaptation to resource changes in mobile devices. In this paper, we explore transaction adaptation techniques in more detail and address the following questions. How does QoS specification support adaptiveness in the transaction model? How can QoS specification specify and associate relaxed ACID properties? We design an XML-based transaction QoS specification language called TQDL to support transaction adaptation and use a distributed calendar application to show the transaction adaptation process. This work is done in the context of an ongoing research project called SyD, System on Mobile devices.
[Implantable hearing aids]. (1991)

The purpose of these hearing aids is to improve the quantity and quality of amplification of the sound wave. Their operating principle is based on the existence of a transducer which transforms the electric signal captured by the microphone into a mechanical, vibrating wave. This transducer can act either directly on the temporal bone by short-circuiting the middle ear (and is then called a bone conduction implant) or directly on the ossicular chain (in which case it is called an ossicular transduction implant). A) There are 2 types of bone conduction implant: the "Audiant Bone Conduction" system of Hough-Vernon (Xomed), where an outside electromagnetic coil sends signals transcutaneously to a magnetic screw embedded on the temporal bone. Bone conduction must be normal. The "Bone Anchored Hearing Aid" (Nobelpharma) where the outside electromagnetic coil sends signals directly to the magnetic screw that is percutaneous. The mean thresholds in bone conduction can reach up to 45 dB. The drawbacks of this system lie in its inaesthetic appearance and the risk of infection. B) With ossicular transduction implants, the transducer may be: either an electromagnetic coil influencing a magnet fixed to the tympanum, on the ossicular chain, or replacing an element of the ossicular chain (these hearing aids are marketed by Richards); or a piezo-electric crystal which produces vibrations when it is subjected to an AC current, and which can be positioned on the stapes (Yanagihara). This system consumes less energy, gives excellent results for the high frequencies, but is more cumbersome.

Efficient Control Of Emissions In FishAnd Meat Processing Plants (2005)

Unpleasant odor is one of the most important pollutants which have a negative effect on the quality of life. Odors are the most objectionable emissions from fish and meat processing plants. Conventional methods for removing odors and flavor-producing chemicals from such units are dilution in the form of masking, wet scrubbing, and burning which has a low efficiency. Odorous gases consist primarily of steam, aromatic compounds, hydrogen sulfide and trimethylamine. The purpose of this study is proposing an efficient method for complete removal of odors from the factory emissions. In this method, the odors can be controlled by separating particulate matters with cyclones, condensing of vapor by condensers and adsorption of the remaining gases by active carbon and silica gel. In this system, about 100 percent of the emissions convert to liquid. By considering temperature and pressure fluctuations, the efficiency of odor removing in different parts of the proposed system are as follows: gas separators and cyclones 15%, heat exchanger 65%, condenser 10% and carbon active and silica gel columns 5%.

Mesenchymal stem cell therapy for advanced liver cirrhosis: A case report (2017)

Mesenchymal stem cell (MSC) transplant may offer an alternative to liver transplantation in patients with end-stage liver disease. However, its efficacy remains uncertain. MSC was performed on a 50-year-old male with decompensated (Child-Turcotte-Pugh grade C) alcoholic liver cirrhosis due to an absence of donors for adult-deceased and living-related liver transplantation. Autologous bone marrow-derived MSCs were harvested from the patient and cultured using standard protocols. The MSCs were subsequently re-administrated into the liver via hepatic intra-arterial infusion on two separate occasions. After infusion, there was an improvement in biochemical parameters (serum total bilirubin, serum albumin), and a reduction of diuretic use for ascites for up to 8 weeks. However, all biochemical and clinical parameters deteriorated on long-term follow-up without any further infusions. The patient eventually succumbed to his disease. MSC transplantation may have a clinical benefit on adult patients with end-stage liver cirrhosis, but this appears to be transitory.
Flame Shape and Spatially Resolved Rayleigh Criterion Using Proper Orthogonal Decomposition (2012)

Chemiluminescence imaging was performed for premixed flames with natural thermoacoustic instabilities in a Rijke tube. The images were phase locked to the natural pressure oscillations in the tube. The use of proper orthogonal decomposition (POD) to identify phase-resolved flame fronts and flame surface area is reported. The flame front results compare favorably to an Abel transform for axisymmetric cases but also work well for cases with non-axisymmetric contributions. The flame area perturbations are compared to previous work using OH planar laser induced fluorescence. The relatively-simpler chemiluminescence approach finds the same flame surface area correlations versus pressure. Additionally, the modes from POD are used to compute local acoustic coupling via the space and time resolved Rayleigh index. It is found that one mode in the decomposition is spatially the same as the Rayleigh index and can be used to characterize the thermoacoustic coupling. This similarity is due to the mode's time constant replicating the phase of the tube's natural pressure oscillations.
Market segment (2014)

This chapter discusses the theories of design have expanded from planned properties of aesthetic appearance to a process in which the object of scrutiny is only a small part of the dynamism and the reach of design. However, it employs autism to exact a critical examination of the multiple factors that design and branding bring to shape the meaning of predominant medicalized disability texts. Thus, autism, Aspergers syndrome and other syndromes on the spectrum accompany us through analysis of disability design and branding as axiology and as meaning-making. Autism spectrum disorders (ASD) has an illustrious past and present, with branders as well as branded arguing about its essence as unique, desirable, pathological or iatrogenic. This region of designed disability is complex and raises some points that are similar to the discussion of ASD, including the cause-marketed credit card and the pride T-shirt.
Subspace-Augmented MUSIC for Joint Sparse Recovery with Any Rank (2010)

We propose a robust and efficient algorithm for the recovery of the joint support in compressed sensing with multiple measurement vectors (the MMV problem). When the unknown matrix of the jointly sparse signals has full rank, MUSIC is a guaranteed algorithm for this problem, achieving the fundamental algebraic bound on the minimum number of measurements. We focus instead on the unfavorable but practically significant case of rank deficiency or bad conditioning. This situation arises with limited number of measurements, or with highly correlated signal components. In this case MUSIC fails, and in practice none of the existing MMV methods can consistently approach the algebraic bounds. We propose subspace-augmented MUSIC, which overcomes these limitations by combining the advantages of both existing methods and MUSIC. It is a computationally efficient algorithm with a performance guarantee.
Speech perception by budgerigars (<i>Melopsittacus undulatus</i>): Spoken vowels (1988)

Budgerigars (parakeets) were trained on a same/different task using operant conditioning. Response latencies were used to construct similarity matrices, and multidimensional scaling procedures were then used to produce spatial maps of these speech stimuli. Budgerigars were tested on stimulus sets consisting of natural exemplars of different vowels produced by a number of male and female talkers. In spite of variation among talkers, budgerigars showed evidence of perceptual categories for different vowels as well as for male and female talkers. The two-dimensional perceptual space for budgerigars discriminating among vowels bears a striking resemblance to the familiar F1-F2 vowel space described by Peterson and Barney [J. Acoust. Soc. Am. 24, 175–184 (1952)]. This suggests that budgerigars use first and second formant information in discriminating among spoken, sustained vowels. [Work supported by NIH.]
Caffeic acid phenethyl ester, a promising component of propolis with a plethora of biological activities: A review on its anti‐inflammatory, neuroprotective, hepatoprotective, and cardioprotective effects (2013)

Caffeic acid phenethyl ester (CAPE) is an important active component of honey bee propolis that possesses a plethora of biological activities. Propolis is used safely in traditional medicine as a dietary supplement for its therapeutic benefits. This review highlights the recently published data about CAPE bioavailability, anti-inflammatory, neuroprotective; hepatoprotective and cardioprotective activities. CAPE showed promising efficacy both in vitro and in vivo studies in animal models with minimum adverse effects. Its effectiveness was demonstrated in multiple target organs. Despite this fact, it has not been yet investigated as a protective agent or a potential therapy in humans. Investigation of CAPE efficacy in clinical trials is strongly encouraged to elucidate its therapeutic benefit for different human diseases after performing full preclinical toxicological studies and gaining more insights into its pharmacokinetics.

An algorithm for computing cutpoints in finite metric spaces (2009)

The theory of the tight span, a cell complex that can be associated to every metric $D$, offers a unifying view on existing approaches for analyzing distance data, in particular for decomposing a metric $D$ into a sum of simpler metrics as well as for representing it by certain specific edge-weighted graphs, often referred to as realizations of $D$. Many of these approaches involve the explicit or implicit computation of the so-called cutpoints of (the tight span of) $D$, such as the algorithm for computing the "building blocks" of optimal realizations of $D$ recently presented by A. Hertz and S. Varone. The main result of this paper is an algorithm for computing the set of these cutpoints for a metric $D$ on a finite set with $n$ elements in $O(n^3)$ time. As a direct consequence, this improves the run time of the aforementioned $O(n^6)$-algorithm by Hertz and Varone by ``three orders of magnitude''.
Memory in posttraumatic stress disorder: Properties of voluntary and involuntary, traumatic and nontraumatic autobiographical memories in people with and without posttraumatic stress disorder symptoms. (2008)

One hundred fifteen undergraduates rated 15 word-cued memories and their 3 most negatively stressful, 3 most positive, and 7 most important events and completed tests of personality and depression. Eighty-nine also recorded involuntary memories online for 1 week. In the first 3-way comparisons needed to test existing theories, comparisons were made of memories of stressful events versus control events and involuntary versus voluntary memories in people high versus low in posttraumatic stress disorder (PTSD) symptom severity. For all participants, stressful memories had more emotional intensity, more frequent voluntary and involuntary retrieval, but not more fragmentation. For all memories, participants with greater PTSD symptom severity showed the same differences. Involuntary memories had more emotional intensity and less centrality to the life story than voluntary memories. Meeting the diagnostic criteria for traumatic events had no effect, but the emotional responses to events did. In 533 undergraduates, correlations among measures were replicated and the Negative Intensity factor of the Affect Intensity Measure correlated with PTSD symptom severity. No special trauma mechanisms were needed to account for the results, which are summarized by the autobiographical memory theory of PTSD.

[A case of intrahepatic cholangiocarcinoma with invasion to right adrenal gland]. (2011)

A 64-year-old woman was admitted for epigastralgia. Abdominal computed tomography demonstrated a large tumor in the right lobe of the liver to adrenal grand. An aspiration tumor biopsy was performed because of difficulty in diagnosing the tumor, and the pathological findings suggested intrahepatic cholangiocarcinoma. At surgery right hepatic lobectomy with caudate lobe combined with right adrenal glandectomy and diaphragmectomy was performed. Pathological findings showed moderately differentiated tubular adenocarcinoma with invasion to right adrenal gland, but no lymph node metastasis was involved nor invasion of lymph vessel and vein. The postoperative course was uneventful and the woman remains recurrence-free for 12 months after the surgery.
Transient Radiation Loading on Spherical Sonar Arrays (1970)

Transient surface pressures generated by a piston set in a spherical baffle or sonar array are obtained in analytical form for velocity steps and CW pulses. Neither the wave-harmonic series, which converges poorly at early times, nor geometric acoustics, which predicts zero pressure on passive elements, is applicable. A technique successfully used for CW impedance calculations was adapted to transient situations. On passive elements, the pressure is computed from Watson's “creeping-wave” formulation, which fails on the active element; there, the pressure is approximated by ignoring baffle curvature. The required Laplace integrals are available in the literature. Numerical results are presented. [Sponsored by Naval Ship Systems Command, under Computer Applications, Inc. subcontract.]
