A single-chip FPGA implementation of the data encryption standard (DES) algorithm (2002)

This paper describes a single-chip implementation of the data encryption standard (DES) using Xilinx XC4000 series field programmable gate array technology under the XACTstep design flow integration system. The implementation details for key scheduling, S-boxes, permutations and the round-function are described. The design process included schematic design, functional and timing simulation and design verification. The final design used 224 combinational logic blocks (CLBs) and 54 input/output blocks (IOBs) and has an encryption speed of 26.7 Mbps.

Marine Natural Products: Pyrrololactams from Several Sponges (1985)

Two pyrrololactams, likely degradation products of more complex known guanidines, were isolated from several marine sponges. 5-Bromo- and 4,5-dibromopyrrole-1-carboxylic acid methyl esters were also isolated. A complex guanidine metabolite, poorly soluble in DMSO, was found to give sharp, reproducible nmr spectra in acid media.
Cell Surface Immunoglobulin (1976)

Abstract The present studies were designed to determine the effect of papain upon IgM and IgD on the surface of murine splenocytes. By using radioiodinated cells, it was shown that IgD is more susceptible to cleavage by papain than IgM. The difference in susceptibility to papain of the two isotypes was not observed when cell lysates were employed, suggesting that attachment to the plasma membrane affects the accessibility of IgM to papain. The major site of attack of the enzyme on IgD appears to be in the hinge region. The possible biologic implications of such a cleavage are discussed.

Preparation and Characterization of Core−Shell Particles Containing Perfluoroalkyl Acrylate in the Shell (2002)

We describe the preparation and characterization of core−shell latex particles, consisting of a polystyrene core, covered with a perfluoroalkyl acrylate shell. The core−shell particles were prepared by a two-stage emulsion polymerization under kinetically controlled conditions and were characterized by transmission electron microscopy, differential scanning calorimetry, and X-ray diffraction analysis. The surface properties of the latex films produced from the core−shell particles were investigated by the contact angle method. Compared with random copolymers or latex blends of styrene and perfluoroalkyl acrylate, the core−shell particles were the most effective to reduce the surface energy of the latex films. The effect of acetone as a cosolvent on the polymerization process was also considered.
Structural models of random packing of spheres extended to bricks: simulation of the nanoporous calcium silicate hydrates (2009)

Abstract\n Structure simulation algorithms of random packing of spheres and bricks have been developed. These algorithms were used to reproduce the nanostructure of the cementitius calcium-silicate-hydrates. The textural parameters (specific surface area, porosity, pore size, etc.) of a C-S-H sample, the main binding phase of cements, have been derived from N2-physisorption experiments. In the same time, these parameters have been simulated by using a sphere-based structural model where the spheres are randomly packed according to several hierarchical levels. The corresponding algorithm has been extended for managing cuboids instead of spheres. The C-S-H sample density is successfully predicted by considering the presence of water in pores defined by the sphere network within 10 nm-size globules and assuming a tobermorite-like skeleton. Simulations with bricks (3x2x1.4 nm3) yield also textural parameters which are consistent with N2-physisorption data but with a globule size (22 nm) twice as big as that obtained when using spheres.
Transforming growth factor‐β1 induces collagen synthesis and accumulation via p38 mitogen‐activated protein kinase (MAPK) pathway in cultured L6E9 myoblasts (2002)

Transforming growth factor-beta (TGF-beta) plays a pivotal role in the extracellular matrix accumulation observed in chronic progressive tissue fibrosis, but the intracellular signaling mechanism by which TGF-beta stimulates this process remains poorly understood. We examined whether mitogen-activated protein kinase (MAPK) routes were involved in TGF-beta1-induced collagen expression in L(6)E(9) myoblasts. TGF-beta1 induced p38 and extracellular signal-regulated kinase (ERK) 1/2 phosphorylation whereas no effect on Jun N-terminal kinase phosphorylation was observed. Biochemical blockade of p38 but not of the ERK MAPK pathway abolished TGF-beta1-induced alpha(2)(I) collagen mRNA expression and accumulation. These data indicate that TGF-beta1-induced p38 activation is involved in TGF-beta1-stimulated collagen synthesis.
Characterization of a Cytosol Progesterone Receptor in Bovine Pineal Gland (1979)

The possible existence of pineal progesterone (P) receptors was assessed in 105,000 g supernatants of bovine pineal glands incubated with 3H-P in the presence of 10 microM cortisol. By charcoal adsorption analysis specific binding (defined as the difference between 3H-P binding in the absence and presence of 1,000-fold excess of unlabeled P) attained its maximum after 60 min at 37 degrees C. Binding was abolished by heating the cytosol or by preincubating it with trypsin. A single population of binding sites with a Kd = 1.64 nM and binding site concentration = 34 fmol/mg of cytosol protein was detectable by Scatchard analysis. In competition experiments the B50 progesterone values (nM) were: P (2), 20 alpha-dihydroprogesterone (12), 20 beta-dihydroprogesterone (25), estradiol (158), testosterone (675) and corticosterone (greater than 1,000). After sucrose gradient centrifugation of pineal cytosol incubated with 3H-P a discrete peak of radioactivity in the 7-8 S region of the gradient was observed, and disappeared following incubation with excess unlabeled P. These results indicate that P receptors are present in the bovine pineal gland.
Algal control and enhanced removal in drinking waters in Cairo, Egypt (2015)

Algal blooms at the major water treatment plants in Egypt have been reported since 2006. While previous studies focused on algal types and their correlation with disinfection by-products, correlation between raw water quality and algal blooms were not explored. Therefore, a survey of Nile water quality parameters at a major water intake in the Greater Cairo Urban Region was conducted from December 2011 to November 2012. Bench-scale experiments were conducted to evaluate the effectiveness of the conventional chloride/alum treatment compared with combined Cl/permanganate pre-oxidation with Al and Fe coagulants during the outbreak period. Addition of permanganate (0.5 mg/L) significantly reduced the chlorine demand from 5.5 to 2.7 mg/L. The applied alum coagulant dose was slightly reduced while residual Al was reduced by 27% and the algal count by 50% in the final treated waters. Applying ferric chloride and ferric sulfate as coagulants to waters treated with the combined pre-oxidation procedure effectively reduced algal count by 60% and better the total organic carbon reduction and residual aluminum in the treated water. Multivariate statistical analysis was used to identify the relationship between water quality parameters and occurrence of algae and to explain the impact of coagulants on the final water quality.
X chromosome-wide analyses of genomic DNA methylation states and gene expression in male and female neutrophils (2010)

The DNA methylation status of human X chromosomes from male and female neutrophils was identified by high-throughput sequencing of HpaII and MspI digested fragments. In the intergenic and intragenic regions on the X chromosome, the sites outside CpG islands were heavily hypermethylated to the same degree in both genders. Nearly half of X chromosome promoters were either hypomethylated or hypermethylated in both females and males. Nearly one third of X chromosome promoters were a mixture of hypomethylated and heterogeneously methylated sites in females and were hypomethylated in males. Thus, a large fraction of genes that are silenced on the inactive X chromosome are hypomethylated in their promoter regions. These genes frequently belong to the evolutionarily younger strata of the X chromosome. The promoters that were hypomethylated at more than two sites contained most of the genes that escaped silencing on the inactive X chromosome. The overall levels of expression of X-linked genes were indistinguishable in females and males, regardless of the methylation state of the inactive X chromosome. Thus, in addition to DNA methylation, other factors are involved in the fine tuning of gene dosage compensation in neutrophils.
HERÁLDICA E GEOGRAFIA (heraldry and geography) (2013)

O artigo examina duas relacoes entre a heraldica e a geografia. A primeira e que hoje o objeto principal da heraldica, os brasoes, servem principalmente para simbolizar identidades territoriais, transmitindo a visao que os seus autores e patrocinadores querem dar do territorio representado pelo brasao. Outra utilidade e que a sua linguagem precisa e rigorosa pode ser usada para descrever de maneira sintetica as configuracoes territoriais que aparecem em mapas e modelos graficos.  Apos ter definido a heraldica e analisado alguns exemplos de brasoes territoriais no Brasil e na Franca, o artigo destaca os seus elementos relevantes para a analise geografica, principalmente as palavras que descrevem a estrutura dos brasoes e podem ser transpostos para mapas e modelos graficos. Palavras-chave : Heraldica, Brasoes, Identidade, Configuracoes territoriais. ABSTRACT The article examines two relationships between geography and heraldry. The first is that today the main purpose of heraldry, coats of arms, are used primarily to symbolize territorial identities, transmitting the vision the authors and their sponsors want to give of the territory represented by them. Another use is its precise and accurate language, which can be used to describe briefly the territorial configurations that appear on maps and graphical models. After defining heraldry and analyzing some examples of coats of arms of territories in Brazil and France, the article highlights its relevance for geographic analysis, especially the words describing the structure of crests, which can be transposed to maps and graphical models. Key words : Heraldry, Coats of arms, Identity, Territorial configurations. RESUME L’article examine deux relations entre heraldique et geographie. La premiere est qu’aujourd’hui l’objet principal de l’heraldique, les blasons, servent principalement a symboliser des identites territoriales, transmettant la vision que leurs auteurs et commanditaires veulent donner du territoire represente par eux. Une autre utilisation est que sa langue precise et exacte peut etre utilisee pour decrire succinctement les configurations territoriales qui apparaissent sur les cartes et modeles graphiques. Apres avoir defini l’heraldique et analyse quelques exemples de blasons de territoires au Bresil et en France, l’article met en evidence sa pertinence pour l’analyse geographique, en particulier les mots qui decrivent la structure des blasons et peuvent etre transposes aux cartes et modeles graphiques.

Dreidimensionale Navigation mit dem EasyGuide<sup>®</sup>-System im Kopf-Hals-Bereich (2000)

&lt;i&gt;Fragestellung:&lt;/i&gt; Die Verbreitung der minimal invasiven Operationstechniken hat zu neuen chirurgischen Herausforderungen geführt. Insbesondere bei veränderter Anatomie und fehlenden anatomischen Landmarken kann die Orientierung auch für den erfahrenen Chirurgen schwierig sein. Hier haben die intraoperativen Navigationssysteme in den letzten Jahren neue Möglichkeiten eröffnet. &lt;i&gt;Methode/Patienten:&lt;/i&gt; Das Navigationssystem EasyGuide&lt;sup&gt;®&lt;/sup&gt; Neuro (Philips Medizinische Systeme, Best, Niederlande) basiert auf einem dreidimensionalen optoelektronischen Messsystem. Infrarotemittierende Dioden an verschiedenen Pointerinstrumenten sowie der Patientenkopfhalterung werden durch ein Kamerasystem erfasst. Mittels weiterer mathematischer Transformation wird die Position der Instrumente in Bezug zum Patienten berechnet und mit den präoperativ gewonnenen radiologischen Datensätzen korreliert. Durch Studien an verschiedenen Phantomen wurden zunächst die technische Genauigkeit und die Grenzen der optischen Detektion evaluiert. Dann erfolgte bei 38 Patienten der operative Eingriff im Bereich der vorderen und seitlichen Schädelbasis mit Unterstützung des Navigationssystems. Hierbei wurden klinische Genauigkeit, Praktikabilität, Vorteile und Probleme des Systems untersucht. &lt;i&gt;Ergebnisse: &lt;/i&gt;Am Phantom bot das System eine Abweichung von unter 1 mm. Im klinischen Einsatz konnte nur mit Kopffixierung und knochenverankerten Referenzmarkern eine Genauigkeit von etwa 1,5 mm erreicht werden. Bei Hautklebereferenzmarkern und flexibler Kopflagerung waren aufgrund der unzuverlässigen Kopfnachführung Abweichungen von bis zu 28 mm möglich. Die präoperative Vorbereitungszeit betrug 20–30 min, je nach Aufwand der Operationsplanung. &lt;i&gt;Schlussfolgerungen:&lt;/i&gt; Das intraoperative Orientierungssystem stellt insbesondere bei untypischen anatomischen Verhältnissen eine deutliche Orientierungshilfe dar. HNO-spezifische Veränderungen sind jedoch notwendig, um den routinemässigen Einsatz im Bereich der Nasennebenhöhlenchirurgie zu gewährleisten.
Active-matrix OLED display backplanes using transfer-printed microscale integrated circuits (2010)

Active-matrix organic light-emitting diode (AMOLED) displays have been fabricated using backplanes with transfer-printed microscale silicon integrated circuits (ICs) in place of conventional thin-film transistors (TFTs). The ICs were fabricated using a commercial semiconductor foundry process, and the wafers were subsequently processed to prepare the ICs for transfer-printing. The microscale integrated circuits were transfer printed onto a glass substrate and interconnected using a single-level, thin-film metallization process. The resulting OLED display exhibited good pixel-to-pixel luminance uniformity, high luminance, excellent controllability, and high switching speed. The transfer-printing process achieved good positional accuracy and high yield.

Efficacy of Chondroitin Sulfate for Painful Knee Osteoarthritis: A One-Year, Randomized, Double-Blind, Multicenter Clinical Study in Japan (2017)

We explored the effects of chondroitin sulfate on knee osteoarthritis in a one-year, randomized, double-blind, dose-comparison study. Patients with painful, Kellgren-Lawrence grade 2-3, osteoarthritis of the knee were treated with oral chondroitin sulfate at a dose of either 260 mg/d (low-dose group, control group) or 1560 mg/d (high-dose group). Symptoms were evaluated by the Lequesne's index and visual analog scale for pain. We made subgroup analyses according to background symptom severity (Lequesne's index ≥8 or <8) in 73 patients. Serum level of cartilage oligomeric matrix protein and hyaluronic acid were also determined. In the subgroup with severe symptoms (Lequesne's index ≥8), the chondroitin sulfate dose of 1560 mg/d improved pain faster after 6 and 9 months' therapy. However, no dose-related effects were found on cartilage oligomeric matrix protein or hyaluronic acid levels. Chondroitin sulfate also had good tolerability. We conclude that chondroitin sulfate is useful for pain control in knee osteoarthritis.
Single base mutation in the type II procollagen gene (COL2A1) as a cause of primary osteoarthritis associated with a mild chondrodysplasia. (1990)

A cosmid clone was isolated that contained an allele for the type II procollagen gene previously shown to be coinherited with primary generalized osteoarthritis in a large family. Affected members of the family had evidence of a mild chondrodysplasia, but they developed progressive osteoarthritic changes in many joints that had no epiphyseal deformities. The clone contained 52 of the 54 exons of the gene. Nucleotide sequencing of greater than 20,000 base pairs from the clone demonstrated that all the coding sequences and all the intron-exon boundaries were normal except for a single base mutation that converted the codon for arginine at position 519 of the alpha 1(II) chain to a codon for cysteine, an amino acid not found in type II collagen from humans or a variety of other species. The mutation was found in all affected members of the family but not in unaffected members or in 57 unrelated individuals.
Stabilisation of a three-dimensional boundary layer by base-flow manipulation using plasma actuators (2015)

The applicability of dielectric barrier discharge plasma actuators for controlling the crossflow-vortex-induced laminar breakdown in a three-dimensional swept-wing-type boundary-layer flow is investigated using direct numerical simulation. Similar to the classical application of suction at the wall the aim is to modify the quasi two-dimensional base flow and to weaken primary crossflow (CF) instability, mainly due to a reduction of the basic CF. Not only localised volumetric forcing by plasma actuators but also CF counter-blowing and spots with a moving wall are investigated to identify effective fundamental mechanisms. It is found that counter blowing always results in partial blockage of the flow and eventually increased CF velocity, whereas moving-wall spots can slightly reduce the CF and the amplitude of crossflow vortices. Using discrete volumetric forcing a significant attenuation even of finite-amplitude crossflow vortices and thus a distinct transition delay is achieved.
[Prostate cancer and quality of life]. (2003)

Faced with equivalent treatments in terms of control of localised prostate cancer, by treatments as different as radical prostectomy and radiotherapy, the analysis of the physical and psychosocial consequences of each treatment is indispensable in determining the therapeutic options proposed to a patient. Current information on the quality of life after treatment of localised and metastatic prostate cancer show effects after treatment that are specific to this pathology (urinary, sexual and digestive problems) and general (physical state and functional capacity, capacity to accomplish all forms of work, capacity to maintain social relations...). These effects nevertheless differ depending of the stage of the disease and the type of treatment.
Signal and power integrity analysis of a 256-GB/s double-sided IC package with a memory controller and 3D stacked DRAM (2013)

This paper presents signal and power integrity analysis of a double-sided flip-chip package. A memory controller is attached on one side of the organic substrate, and 3D-stacked, disaggregated memory chips, integrated with through silicon vias (TSVs), are connected on the opposite side. The signaling path of this 3D memory system consists of a short channel consisting of wafer-level redistribution layer (RDL) traces and small TSV vias. The signal integrity is not a source of concern for this extremely short channel; power integrity, however, poses significant challenges and consequently can limit the achievable data rate of this system. The double-sided flip-chip packaging p resents unique challenges in the design of l o w-impedance the power delivery network (PDN) and circuit design with low-sensitivity to power supply noises. All physical layers are code sign to optimize the integrated 3D package within electrical and manufacturing constraints in conjunction with robust circuit design that meets the power constraint. The detailed signal integrity analysis is presented to design robust link with low-swing signals and power integrity analysis to optimize the PDN designs to meet the PDN impedance targets.
PID tuning for improved performance (1999)

In this paper, a simple PID controller design method that achieves high performance for a wide range of linear self-regulating processes is proposed. Satisfactory responses can be expected for processes with various dynamics, including those with low- and high-order, small and large dead time, and monotonic and oscillatory responses. The method is developed based on a second-order plus dead time modeling technique and a closed-loop pole allocation strategy through the use of root-locus. Simulation examples and real-time experiments are given to show the effectiveness and flexibility of the controller in handling processes of different characteristics.
