Physicochemical and Functional Properties of Tropical Tuber Starches: A Review (2002)

The tropical tuber crops contain starch as the major component and thus act as important source of starch. Except cassava and to a smaller extent sweet potato, starch from other tuber crops has not been exploited for industrial applications partly because of difficulty in the extraction of the pure starches and partly because of non-availability of information about the properties of these lesser known starches. This review attempts at collating data available on the physicochemical and functional characteristics of the tropical tuber starches, highlighting their unique properties and potential field of applications. The physicochemical properties like granule shape and size, X-ray diffraction (XRD) patterns, amylose content, or content of non-starchy components, show considerable variation among the tuber starches. In addition, factors like genetic origin, environmental conditions and age of the plant also influence the properties. The starch granules of Colocasia esculenta and Dioscorea esculenta tubers are very small whereas those of Canna edulis are very large. XRD patterns of yam starches are generally ‘B’, while the aroid starches possess ‘A’ patterns. DSC gelatinisation temperatures are low for cassava starch and high for the aroid starches. The functional characteristics like viscosity, swelling power and solubility also depend on a number of factors such as varietal variation, method of extraction, processing conditions and instruments used for analysis. Viscosity is high for cassava and C. edulis starches, but low for most aroid starches. Clarity is good for cassava and yam starches compared to the others. Digestibility also varies among the starches. The diversity available in the tuber starches shows that some of the starches can be used in place of chemically modified starches available on the market. The realisation of their importance can help in value addition of these neglected crops and also provide starch with special properties for specific applications.
Structural Effects on the Properties of Nonionic Surfactants. I. The Synthesis and Some Surface Activities of Acetal Type Homogeneous Nonionics (1972)

Abstract Higher aliphatic aldehydes (C8–C16) were treated in the presence of mineral acid with several pure polyoxyethylene glycols (m : 2–6), to give the corresponding acetals (AG types) with a general formula RCH[O(C2H4-O)mH]2. These AG types are soluble in water, fairly stable in neutral and weakly basic aqueous solutions, and they exhibited the characteristic properties of nonionics. The hydration of the geminal polyoxyethylene (POE) chains are discussed on the basis of the data of unexpectedly low cloud points. Surface tension measurements on the aqueous solutions of AG types indicated that the critical micelle concentration (CMC) value decreases with an increment of oxyethylene units (m), and that the molecular area does not depend so greatly on m and is significantly smaller than that predicted from the data of conventional nonionics (S types) having one hydrophobic and hydro-philic chain each. For the gross effects of AG types, it has been found that the foam stability is considerably low and the dependence of the wetting power for canvas discs on m is larger than that of S types. The results are discussed on the basis of structural characteristics related to the unfavorable hydration and restricted configuration of the geminal POE chains. The acid-catalyzed hydrolysis of AG types in the micellar solution was significantly slower than that of acetaldehyde diethylacetal in water.
New Immunosuppressive Therapies in Uveitis Treatment (2015)

Uveitis is an inflammatory process that initially starts in the uvea, but can also affect other adjacent eye structures, and is currently the fourth cause of blindness in developed countries. Corticoids are probably the most widespread treatment, but resorting to other immunosuppressive treatments is a frequent practice. Since the implication of different cytokines in uveitis has been well demonstrated, the majority of recent treatments for this disease include inhibitors or antibodies against these. Nevertheless, adequate treatment for each uveitis type entails a difficult therapeutic decision as no clear recommendations are found in the literature, despite the few protocolized clinical assays and many case-control studies done. This review aims to present, in order, the mechanisms and main indications of the most modern immunosuppressive drugs against cytokines.

On the masking countermeasure and higher-order power analysis attacks (2005)

Masking is a general method used to thwart differential power analysis, in which all the intermediate data inside an implementation are XORed with random Boolean values. As a consequence, the power consumption of the running implementation becomes unpredictable, making first-order power analysis attacks unpractical. Several recent works have shown that such protected designs are still susceptible to higher-order power analysis attacks. In this paper, we propose an extension of the previously introduced higher-order techniques, based on a more general power consumption model, and evaluate its actual feasibility. In particular, we discuss the number of power traces required to mount successful attacks. We also illustrate how this number is affected by parallel computations, making certain implementation contexts (e.g. smart cards, 8-bit processors) more susceptible than others (e.g. FPGAs, ASICs).
Rare Earth Metal Ions for DNA Hydrolyses and Their Use to Artificial Nuclease<sup>1</sup> (1994)

Abstract Phosphodiester linkages in linear DNAs are efficiently hydrolyzed by rare earth metal salts. The activities of CeCl3 and Ce(NH4)2(NO3)6 are especially large. Artificial hydrolytic nuclease for highly selective scission of DNA has been prepared by the attachment of Ce(IV) ion to a DNA oligomer as a sequence recognizing moiety.
Poly‐α‐olefin‐based synthetic lubricants: a short review on various synthetic routes (2011)

ABSTRACT This paper reviews various synthetic protocols for poly‐α‐olefin (PAO) synthetic lubricant base stocks that have evolved over the years. Apart from conventional Lewis acid catalysts known for the synthesis of poly‐α‐olefins, such as aluminium trichloride and boron trifluoride, several new catalysts such as metallocenes and ionic liquids have been reported by various researchers. With increasing options of catalytic processes available, it is now possible to produce tailor made PAOs and thus control the properties of the end products, such as viscosity and the viscosity index. Although 1‐decene is the most widely used monomer for PAO application, researchers have used a wide range of monomers from 1‐hexene to 1‐tetradecene and internal olefins in some cases.

Homozygous mutation in the prokineticin-receptor2 gene (Val274Asp) presenting as reversible Kallmann syndrome and persistent oligozoospermia: Case Report (2008)

Prokineticin 2 (Prok2) or prokineticin-receptor2 (Prok-R2) gene mutations are associated with Kallmann syndrome (KS). We describe a new homozygous mutation of Prok-R2 gene in a man displaying KS with an apparent reversal of hypogonadism. The proband, offspring of consanguineous parents, presented at age 19 years with absent puberty, no sense of smell, low testosterone and gonadotrophin levels. Magnetic resonance imaging showed olfactory bulb absence. The patient achieved virilization and spermatogenesis with gonadotrophin administration. Two years after discontinuing hormonal therapy, he maintained moderate oligozoospermia and normal testosterone levels. Prok2 and Prok-R2 gene sequence analyses were performed. The proband had a homozygous mutation in Prok-R2 exon 2 that harbours the c.T820>A base substitution, causing the introduction of an aspartic acid in place of valine at position 274 (Val274Asp). His mother had the same mutation in heterozygous state. This report describes a novel homozygous mutation of Prok-R2 gene in a man with variant KS, underlying the role of Prok-R2 gene in the olfactory and reproductive system development in humans. Present findings indicate that markedly delayed activation of gonadotrophin secretion may occur in some KS cases with definite gene defects, and that oligozoospermia might result from a variant form of reversible hypogonadotrophic hypogonadism.
Filler induced metal crush failure mechanism in plastic encapsulated devices (2003)

Filler particles from the mold compound can give rise to local stress on the integrated circuit die surface, cracking the passivation, resulting in a metal to polysilicon short or a metal to metal short. The metal damage under the passivation is termed as metal crush. This study shows that metal crush takes place only in plastic encapsulated devices and is predominant in plastic packages with silicone gel die overcoat. Experiments and finite element simulations have shown that the use of ultra low stress molding compound without silicone gel die overcoat eliminates metal crush failures. This study also presents the minimum silicone gel die overcoat thickness that prevents metal crush failures in plastic encapsulated devices with low stress molding compound and silicone gel die overcoat.
Dielectric properties of binary polyvinylidene fluoride/barium titanate nanocomposites and their nanographite doped hybrids (2011)

Binary polyvinylidene fluoride/barium titanate (PVDF/BaTiO 3 ) and its nanographite (GN) doped ternary nanocomposites were fabricated using a simple solution casting process followed by compression molding. The dielectric behavior of such hybrids over a wide frequency range was studied. Additions of GN with contents close to the percolation threshold were found to be very effective to enhance dielectric permittivity of the PVDF/BaTiO 3 nanocomposites. In this regard, the electrical behavior of ternary PVDF/BaTiO 3 /GN hybrids can be explained in terms of the percolation theory. Furthermore, both dielectric constant and electrical conductivity of hybrids were found to be strongly frequency and temperature dependent.
Towards 400GBASE 4-lane Solution Using Direct Detection of MultiCAP Signal in 14 GHz Bandwidth per Lane (2013)

We report on an experimental demonstration of 102 Gbit/s transmission over a 15km single wavelength and polarization fiber link with 14GHz 3dB bandwidth. Novel multi-band CAP signaling allows for a 4-lane 400GBASE long reach solution.
The New L2 Civil Signal (2001)

This paper and a companion article in the September 2001
issue of GPS World Magazine(1) describe the new L2 civil
signal (L2C) which will be transmitted by modernized IIR
(IIR-M) and all subsequent GPS satellites. The first
IIR-M satellite is scheduled to be launched in 2003.
This paper covers seven main topics: the development
framework, the signal description, signal acquisition and
code tracking, code tracking accuracy, message
sequencing options, relative signal performance, and the
L2C design tradeoffs. The paper concludes with a discussion of why the two new GPS signals will affect
future product design choices in significant ways,
concluding that L2C could become the most widely used
GPS signal of all.
Both L2C and L5 recently were described at an L2/L5
Industry Day public presentation on 5/02/01 at the
Aerospace Corporation in El Segundo, CA, and again at
an L2/L5 Public Forum on 6/29/01 at the Federal
Aviation Administration (FAA) in Washington, DC. The
charts presented at these events and the draft signal
specifications have been posted on the NAVCEN web site
(www.navcen.uscg.gov) under the modernization topic
and on the GPS Joint Program Office (JPO) web site

Severe anemia after gastrointestinal hemorrhage in a Jehovah’s Witness: New treatment strategies* (2002)

This case demonstrates that the concurrent administration of hemoglobin-based oxygen carriers and recombinant human erythropoietin in severe, life-threatening anemia (hemoglobin, 3.5 g/dL) was associated with patient survival and a significant increase in hemoglobin to 7.6 g/dL, without the administration of allogeneic blood. Hemoglobin-based oxygen carriers can adequately serve as initial therapy to maintain tissue oxygen delivery while awaiting the maximal effect of recombinant erythropoietin on bone marrow red blood cell production. High-dose recombinant human erythropoietin offers these patients the best chance for normalization of hematocrit and survival in the long term.
Patient’s reaction showed the power of quiet companionship (2011)

Codon—anticodon pairing A model for interacting codon—anticodon duplexes located at the ribosomal A‐ and P‐sites (1992)

The interaction between two codon-anticodon duplexes of the ribosomal A- and P-site-bound tRNAs is the key feature of the proposed model. This interaction prohibits non-canonical base pairing at the first and second positions of the codon and controls base pairing at the third position (wobbling rules ensuing from the model are in good accord with those generated from experiments). The model is capable of predicting codon context effects. It follows from the model that modifications of the first anticodon residue of the P-site tRNA can affect the stability of the A-site duplex, and that the translation of a DNA single chain analogue of mRNA should be accompanied by non-canonical base pairing at all three positions of the codon. These predictions of the model can be subjected to experimental tests.
Community-Associated Methicillin-Resistant <i>Staphylococcus aureus</i>: Trends in Case and Isolate Characteristics from Six Years of Prospective Surveillance (2009)

CA-MRSA increased dramatically from 2000 to 2005. Changes in the predominant PFT have impacted susceptibility profiles of CA-MRSA, including ICR. Continued surveillance is needed to monitor the changing epidemiology of CA-MRSA and to inform clinical decisions.
Hebbian learning with winner take all for spiking neural networks (2009)

Learning methods for spiking neural networks are not as well developed as the traditional rate based networks, which widely use the back-propagation learning algorithm. We propose and implement an efficient Hebbian learning method with homeostasis for a network of spiking neurons. Similar to STDP, timing between spikes is used for synaptic modification. Homeostasis ensures that the synaptic weights are bounded and the learning is stable. The winner take all mechanism is also implemented to promote competitive learning among output neurons. We have implemented this method in a C++ object oriented code (called CSpike). We have tested the code on four images of Gabor filters and found bell-shaped tuning curves using 36 test set images of Gabor filters in different orientations. These bell-shapes curves are similar to those experimentally observed in the V1 and MT/V5 area of the mammalian brain.
Temporal video compression by discrete wavelet transform (2006)

Abstract: This paper investigates the use of discrete wavelet transform in temporal video compression. The proposed method has the advantage of being independent of the number of frames. After decompression, it also reproduces video images that have relatively high quality of visualization.
The absence of human papilloma virus (HPV) related parameters in sexually non-active women. (1994)

In to order to investigate the prevalence of HPV related parameters in sexually non-active women, smears of 75 virgins were microscopically reviewed for alterations caused by HPV i.e. koilocytosis, parakeratosis and multinucleinization. In none of these smears were the mentioned parameters seen together, so the diagnosis of HPV infection could not be assessed. In an age-matched control population consisting of 75 sexually active women smears were reviewed. In this group 10 smears (13%) were found positive for HPV infection, well in accordance with literature.
Navigation in partially unknown, narrow, cluttered space (2003)

Navigation of non-circular mobile robots in narrow, cluttered, partially unknown environments is considered. The paper introduces a planner capable of planning paths in these environments, while taking specific kinematic constraints and user defined optimality criteria into account. The planning is based on a graph, built and maintained in a variable, explicit configuration space representation of robot and workspace.
Iron uptake and detection of an outer membrane iron-siderophore receptor protein from Pseudomanas aeruginosa PA01 (1988)

Under iron-restricted conditions, Pseudomonas aeruginosa PA01 produced large amounts of the fluorescent pigment, pyoverdine, which is a siderophore of this organism. Maximum iron uptake was found in P. aeruginosa PA01 only in the presence of its own pyoverdine and not in those from other Pseudomonas species, suggesting species specificity of pyoverdine for ion uptake. An iron-binding protein (60 000 mol.wt.) present in outer membranes of iron-restricted cultures was absent from iron-supplemented cultures.
Thermal recovery after passage of the pulmonary circulation assessed by deconvolution (1988)

For indicator-dilution studies, complete thermal recovery after passage of heat through the pulmonary circulation would be desirable. However, the results in the literature obtained by extrapolation techniques are inconsistent. To overcome problems of the extrapolation approach, transport functions of the pulmonary circulation (including the left heart) were computed by deconvolution of pulmonary arterial and aortic pairs of thermodilution curves after central venous indicator injection (10 ml of an ice-cold blood indocyanine green dye mixture). Thermal recovery was determined as the finite integral of the transport function. Thirteen mongrel dogs under piritramid-N2O anesthesia were examined under base-line conditions, in orthostasis to alter the distribution of pulmonary blood flow (9 dogs), and in oleic acid edema (8 dogs). Using the deconvolution approach, thermal recovery was 0.97 +/- 0.04 under base-line conditions, 0.96 +/- 0.03 in orthostasis, and 0.96 +/- 0.05 in pulmonary edema. Thermal recovery determined from extrapolated dilution curves was greater than 100% in all groups, a physically impossible finding. It is concluded that thermal recovery is incomplete but insensitive with respect to the distribution of blood flow and to the size of the extravascular compartment. Monoexponential extrapolation is unsuited for the determination of thermal recovery.
Frequency Tunable Antenna Using a Magneto-Dielectric Material for DVB-H Application (2013)

This paper presents an ultracompact antenna design suited for digital video broadcasting-handheld (DVB-H) reception devices. The DVB-H frequency band is ranging from 4 70 to 862 MHz and divided in 49 channels of 8 MHz. Designed to be integrated in a tablet, it is not only heavily miniaturized (λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> /49 × λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> /71 ×λ <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> /160 at 470 MHz), but also able to cover each channel thanks to the use of a magneto-dielectric material. The advantage of using such a material is studied and described in this paper. Moreover, the operating frequency is continuously tuned over the whole DVB-H band by the integration of a varactor diode. This varactor diode has been characterized and modeled to properly cosimulate its behavior within the antenna. Limitations in terms of accepted power by the diode are emphasizing. Finally, the antenna design, including both magneto-dielectric material and varactor diode is integrated in the DVB-H receiver device. Measurement performances are presented and discussed.
Study of Base Additives for Use in a Single Layer 193nm Resist Based Upon Poly(norbornene/maleic anhydride/acrylic acid/tert-buty Acrylate). (2001)

We report on a study of the chemical and lithographic behavior in a 193nm single layer resist of two types of base additives, aminosulfonates opium and tetrabutylammonium carboxylate salts. These additives were examined because of their low potential for undesirable reaction with maleic anhydride or acrylic acid repeat units in norbonene/maleic anhydride/acrylate based 193nm resins. For ammonium carboxylate additives it will be shown that using these gives comparable lithographic performance to a standard formulation containing an amine additive. For aminosulfonate onium salts a study was done of the relationship between chemical structure of these additives and their thermal stability and the lithographic performance imparted by these to a 193nm single layer resist system. It will be shown that the decomposition temperature is a function of the basicity (nucleophilicity) of the counter anion decreasing with increasing basicity but can be improved by going from an iodonium to a sulfonium chromophore. Cyclamate and cysteate opium salts will be shown to provide good lithographic performance with good post-exposure bake delay latitude.
Bacterial Leaching of Metal Sulfides Proceeds by Two Indirect Mechanisms via Thiosulfate or via Polysulfides and Sulfur (1999)

The acid-insoluble metal sulfides FeS2, MoS2, and WS2 are chemically attacked by iron(III) hexahydrate ions, generating thiosulfate, which is oxidized to sulfuric acid. Other metal sulfides are attacked by iron(III) ions and by protons, resulting in the formation of elemental sulfur via intermediary polysulfides. Sulfur is biooxidized to sulfuric acid. This explains leaching of metal sulfides by Thiobacillus thiooxidans.
Microprocessor technologies for the 21st century (1999)

In the past decade, computer technology advances have fundamentally changed practices in business and personal computing. With computer and communication networks extending connectivity to virtually every corner of the planet, the image of a wired world is no longer just a dream, it is a reality. The driving force behind this new computing revolution is rapid advance in processor technology-Moore's Law. Designing a modern processor is a complex task that demands the best trade-offs in its hardware and software components. This talk presents the features and future of Intel microprocessors and their architectures.
