Le camp de Rivesaltes : bilan et perspectives d’un lieu d’ostracisme (1939-2007)
Authors: Lebourg Nicolas
Published: March 2015

Ein Ort der Ausgrenzung : Das Lager in Rivesaltes (1939-2007), Bilanz und Perspektiven.

Schon seit seiner Eröffnung im Jahre 1939 war das Militärlager Joffre in Rivesaltes im Roussillon ein Ort an dem bestimmte Populationen ausgegrenzt werden sollten. Spanische Flüchtlinge, europäische Juden, später Kollaborateure, deutsche Kriegsgefangene, algerische Flüchtlinge, illegale Einwanderer und viele mehr wurden hier nacheinander interniert, bis das Lager 2007 verlegt wurde. Diese Liste zeigt konjunkturelle Anpassungen aber auch eine geopolitische Strukur, zunächst eine europäische Dimension 1939-1948, dann eine Ausrichtung hin auf den Brennpunkt Mittelmeerraum 1952-2007. Daneben sieht man auch eine soziale und historische Dimension der Ausgrenzung verschiedener Kategorien von Individuen und deren Platz im Verhältnis zwischen Staat und Gesellschaft.
La concubine de Raimond Ier, filia Odoini, et sa parentèle rouergate vers 880-vers 1013
Authors: Panfili Didier
Published: March 2015

La fille d’Odoin, cette concubine du comte Raimond Ier dit de Rouergue mentionnée dans le codicille comtal de 961, a échappé jusque-là à toute identification. Les sources rouergates permettent de la rattacher à une puissante lignée, fortement implantée dans le nord-ouest de ce pagus et que l’on peut suivre depuis la fin du IXe siècle. L’importance du patrimoine de niveau vicomtal, les réseaux noués mais aussi cette situation stratégique aux marges du Quercy et de l’Auvergne font que cette lignée des Ictier devient un enjeu dans la lutte entre les princes guilhelmides et raimondins au moment où se déclenche la guerre pour la détention du titre ducal. Alors que le comte Raimond a fait d’une Ictier sa concubine et que l’abbaye de Conques passe sous le contrôle des Guilhelmides via Étienne, l’abbé-évêque de Clermont, les tensions se multiplient et les Ictier s’éloignent un temps du monastère. À Conques, les conséquences de ce conflit se laissent percevoir dans l’opposition des réseaux ennemis jusqu’aux années 1010.
Le prince et l’expert : les juristes à la cour rhodanienne du comte Raimond V de Toulouse (1149-1194)
Authors: Macé Laurent
Published: March 2015

MACÉ (Laurent), Der Prinz und seine Ratgeber : die Juristen am Hof des Grafen Raimunds V. von Toulouse (1149-1194) in Saint-Gilles, Annales du Midi, 123, Nr. 276, Oktober-November 2011, S. 513-532. In dieser Studie vereint Laurent Macé einige noch verstreute Kenntnisse über das unmittelbare Umfeld des Grafen Raimund V. von Toulouse. Die Arbeiten von André Gouron haben den Autor dazu inspiriert, sich für die Gruppe der Juristen zu interessieren, die dem Grafen bei seinen Gerichtstagen am Unterlauf der Rhone in der zweiten Hälfte des 12. Jh. zur Seite stehen. Prosopographische Analysen erlauben es uns, den Parcours von vier Personen zu verfolgen, die zum Umfeld der bischöflichen Schule in Nîmes gehörten. Sie waren Richter und Hauptsekretäre der gräflichen Kanzlei und interpretierten für den Grafen das römische Recht als Glossatoren ; ihre Auslegung und Interpretation der Gesetze hatte einen dauerhaften Einfluss auf die Rechtspraxis in Südfrankreich. Zur Zeit der großen kriegerischen Auseinandersetzungen in Südfrankreich zwischen den Grafen von Toulouse und dem König von Aragon standen diese Juristen dem Prinzen zur Seite. Ihre Präsenz erklärt auch, warum der Hof des Grafen von Toulouse feste, professionelle Strukturen entwickelte. Die Juristen wurden zu ständigen Ratgebern, die wussten, wie man aus juristischen Argumenten handfeste politische Forderungen schmieden konnte.
Jean sans Terre et les origines de la Gascogne anglaise : droits et pouvoirs dans les arcanes des sources
Authors: Vincent Nicholas
Published: March 2015

Juan sin Tierra y los orígenes de la Gascuña inglesa : derechos y poderes en el laberinto de las fuentes.

Después de la caída de la Normandía y de Angeo en 1204, Gascuña resultó ser la última parte del imperio de Enrique II que había quedado bajo la autoridad de los reyes Plantagenet. Frente a las opiniones contradictorias según las cuales se considera que Gascuña estaba gobernada ya con brutalidad ya al contrario con desidia por el rey Juan (1199-1216), este artículo intenta evaluar el grado de implicación del rey en Gascuña así como la administración de la justicia aleatoria en la región. Se rectifican varios errores debidos a la casualidad de la conservación de las pruebas documentales. Para concluir podemos decir que el rey Juan se interesaba sólo de manera periférica por Gascuña pero que, como en el caso de otras muchas «colonias » marginales, su influencia sobre sus reyes extranjeros era casi tan importante como la deellos en la emergencia en el sur de un tipo de gobierno propio de los Plantagenet.
L’exemple d’une ville au pouvoir judiciaire souverain : Avignon au XIIIe siècle
Authors: Leroy Nicolas
Published: March 2015

Avignon im 13. Jh., eine Stadt mit souveräner Gerichtsbarkeit.

Durch seine besondere geografische Lage kam Avignon am Anfang des 12. Jh. in den Genuss einer Autonomie, die schon an Unabhängigkeit grenzte. Diese besondere Situation dauerte bis in die Mitte des 13. Jh. und wird besonders bei der Gerichtsbarkeit deutlich. In dieser Zeit verfügte Avignon über eine souveräne

potestas judicandi, die ganz in den Händen der städtischen Behörden lag. Sie erlaubte es den Bürgern Avignons eigene gerichtliche Verfahren einzuführen, die die städtische Gerichtsbarkeit definierten. Diese Prozeduren sind stark durch das Römische Recht beeinflusst und man findet darin vor allem das Anklagemodell der Zivilprozesse. Was die Strafgerichtsbarkeit betrifft, zeigt sich Avignon offen für juristische Innovationen, wie sie auch in den italienischen Städten dieser Epoche zu finden sind (Entwicklung des Inquisitionsprozess und des richterlichen Schiedsspruch). In Avignon offenbart sich ein Rechtssystem, das zwischen zwei Epochen liegt. Einerseits Elemente der mittelalterlichen Gerichtsbarkeit, andererseits moderne Gerichtsverfahren, die auf dem Römischen Recht gründen. Am Beispiel Avignon zeigt sich die Rolle der kleinen, südfranzösischen Städte bei der Verbreitung der juristischen Innovationen, die vorher in den italienischen Städten entwickelt worden waren.
L’État forestier et les luttes d’influence dans la maîtrise particulière de Comminges (seconde moitié du XVIIe siècle)
Authors: Poublanc Sébastien
Published: March 2015

The State Forester and Struggles for Influence in the Water and Forest Jurisdiction of Comminges (Second Half of the 17th Century).

The monarchy recognized early on the necessity of protecting forests and of organizing locally their exploitation, recognition which led to the development of a form of authority and power based on the possession and the management of forests up to the accession of Louis 14. The evolution of State demand during the second half of the 17th Century imposed a redefinition of wood production on the scale of the kingdom. Reform commissions were sent in each forest region in order to investigate the importance of forest property and to determine the best ways to use it. In the Toulouse forest region, upon which depended Comminges, it was Louis de Froidour, the best known forester in the kingdom, who was in charge from 1665 to 1673. His careful work allowed him to put in place an institution that he judged capable of responding to the needs of the monarchy. Interference of the Water and Forest administration in local politics, however, engendered a reorganizing of power centered on forest ressources which then became symbolic objects, founding regional identity
L’image du Midi sous la Restauration : variations autour du tempérament méridional
Authors: Tort Olivier
Published: March 2015

Images of the Midi during the Restoration : variations on the Southern character.

The White Terror of 1815 strongly reactivated a number of symbolic representations on Southerners in the litterature of the time. Between repeating common stereotypes relating to the influence of climate and the shadow cast by regional economic difficulties which reflected on the character of inhabitants and on their hospitality, writings during the Restoration showed the Midi as a place where the expression of French political passions was particularly exacerbated. If observers of the time used the South as an exemplary territory of their own opinions – White Midi and Democratic Midi – they were nonetheless confronted with the importance of internal divisions and with the strong variations seen in different cities. Southerners themselves deplored the image of their society permanently torn by the demons of internal disputes.
L’arbre de la liberté dans le Midi : conflictualité autour d’un signe révolutionnaire (1814- 1852)
Authors: Fureix Emmanuel
Published: March 2015

Der Freiheitsbaum in Südfrankreich : Streitobjekt der Revolution (1814-1852).

Besonders im Süden Frankreichs war der Freiheitsbaum im 19. Jh. weit mehr als ein Überrest und Erinnerung an die Französische Revolution. Während der ersten Hälfte des 19. Jh. wurden diese Freiheitsbäume immer wieder entfernt und zeigen so die jeweiligen Krisen, Revolutionen oder Konterrevolutionen. Sie spiegeln auch interne Kämpfe um die Herrschaft über den öffentlichen Raum wider und das auf ganz unterschiedlichen Ebenen. Ob positiv oder negativ, die verschiedenen Gruppen vor Ort wollten sich den Freiheitsbaum als symbolisches Objekt aneignen. Anhand örtlicher und gesamtfranzösischer Archivdokumente beschreibt der Autor, wie dieses Symbol gesellschaftlich und politisch benutzt wurde. Dabei wird der Prozess ein wenig deutlicher, der aus dem Freiheitsbaum das spätere Symbol machte. Auch die politische Meinungsbildung und die Entstehung politischer Identitäten werden dokumentiert. Man sieht wie aus einer gerade noch tolerierten anderen politischen Meinung, politische Plurialität entsteht. Der Artikel untersucht vor allem drei Momente im Kampf um den Freiheitsbaum : 1814-1816, 1830-1833 und 1848-1852.
La « républicanisation » de l’espace public montpelliérain. Politique et géographie symbolique dans le « Midi rouge » (1848-1914)
Authors: Lacombrade Philippe
Published: March 2015

The « Republicanization » of Public Space in Montpellier : Political and Geographical Symbols in the « Red Midi » (1848-1914).

Between 1848 and 1914, Montpellier was the theater of a no holds barred struggle between Republicans and Legitimists. In a city that had been strongly marked by the imprint of absolute monarchy, the combat for control of local power was duplicated with a conflict for the symbolic appropriation of public space. Monuments, squares, streets and celebrations thus constituted the major stakes of the confrontation between « Reds » and « Whites » . On the eve of World War I, the symbolic geography of Montpellier testifies to the republican triumph but also of the capacity of resistance of a Catholic and royal heritage that was becoming patrimonialized.
D’Arbûnah à Sakhrat Abinyûn : quelques hypothèses sur la présence musulmane en Narbonnaise et dans la vallée du Rhône au vu des découvertes monétaires
Authors: Parvérie Marc
Published: March 2015

Desde Arbûnah hasta Sakhrat Abinyûn : algunas hipótesis sobre la presencia islámica en Narbonense y en el valle del Ródano a partir de los descubrimientos de monedas.

Con los hallazgos cada vez más numerosos de monedas arabomusulmanas en el Sur de Francia podemos cuestionar las fuentes y hacer el balance de la presencia islámica en Narbonense y más allá del Ródano. Los ocho nuevos hallazgos – tres dirhames y cinco fulûs – permiten un nuevo enfoque. Primero la presencia de fulûs

en sitios ocupados en la Antigüedad tardía parece indicar que en la parte sur de la provincia, desde los Pirineos hasta Narbona, conquistada por las armas, se instalaron tropas árabes, no sólo en la misma capital de la provincia, Narbona, y en Ruscino, centro administrativo y militar en la vía Domitia, sino también en fincas agrícolas de la ribera del Aude. Por otra parte el hallazgo de fulûs cerca de Orange es una primera prueba arqueológica de la presencia militar de los árabes de una duración de unos cuatro años al este del Ródano lo que ya señalaban las fuentes tanto árabes como francas. Por fin comprobamos que los dirhames de plata del emirato omeya de al Andalus circulaban después de la conquista carolingia de 759, de la misma forma que en Aquitania a principios del siglo IX.
De la madîna à l’almunia. Quelques réflexions autour du peuplement musulman au nord de l’Èbre
Authors: Sénac Philippe
Published: March 2015

Desde la madîna hasta la almunia. Algunas reflexiones acerca de la población islámica en el norte del Ebro.

Les investigaciones sobre el valle del Ebro han dado a conocer la existencia de un gran número de hábitat rurales de época islámica (siglos VIII-XII) acerca de los cuales las fuentes, árabes y latinas, son muy parcas. La presencia de numerosas fortalezas al servicio de la autoridad pública, de establecimientos fortificados de época omeya y de numerosas propiedades pertenecientes a élites urbanas (almunias) muestra que, en esas tierras de frontera, la huella del Estado y de las ciudades es manifiesta, al lado de estructuras de población comunitarias bien estudiadas en la región de Valencia o en Andalucía y más frecuentes cerca del Mediterráneo. Teniendo en cuenta la carencia de informaciones y de vestigios materiales de los siglos VIII y IX, las encuestas más recientes, desde Cataluña hasta la Rioja, parencen indicar que la islamización definitiva de los campos fue lenta, que se hizo progresivamente a partir de las ciudades (mudun) luego de las fortalezas (husûn), y que en la primera mitad del siglo X aparecieron nuevos establecimientos propiamente « islámicos » , al lado de antiguas estructuras de población que se habían mantenido en la pars rustica de las villae antiguas.
Le royaume de Navarre et le territoire de Basse-Navarre (1512-1524)
Authors: Ostolaza Elizondo Maria Isabel , Adot Lerga Álvaro
Published: March 2015

Das Königreich Navarra und Nieder-Navarra (1512-1524).

1512 änderte sich die Geschichte Navarras grundlegend. Ferdinand von Aragon, Vormund und Vater Johannas von Kastilien, annektierte Navarra. Vorhergegangen waren jahrelange Verhandlungen und Verträge zwischen der kastilischen und aragonesischen Krone und dem Haus Foix-Albret. Ferdinand half die Gunst der Stunde und der Vorwand für Kastilien sichere Grenzen zu etablieren. Der letzte legitime König Navarras konnte am 17. 7. 1512 in Blois durch ein Bündnis mit Ludwig xII. gerade noch seine Besitzungen nördlich der Pyrenäen halten. Das Bündnis opferte jedoch den anderen Teil Navarras und an der Grenze zwischen Navarra und Kastilien, um Guipuscoa, Alava, Rioja und Soria, entbrannte bald ein Streit zwischen Frankreich, Aragon-Kastilien und ihren jeweiligen Bündnispartnern. Ferdinand der Katholische gab Nieder-Navarra (merindad de Ultrapuertos), das sechste Merindad Navarras, auf, obwohl es das Hinterland des Königreichs war, wohl auf Grund der Pyrenäen und seine Nähe zur unabhängig gebliebenen Vizegrafschaft Béarn, das immer noch das zentrum der alten königlichen Dynastie der Foix-Albret geblieben war. Diese neue Situation machte aus Pamplona eine der wichtigsten Festungen des Königsreichs, als Einfallstor nach Kastilien und als Schlussstein im Ausbau des kastilischen Machtbereichs.
Des riches et des pauvres : bienfaisance et pouvoir en (contre) Révolution dans le Journal de Nîmes (1789-1790)
Authors: Alzas Nathalie
Published: March 2015

Of Rich and poor : Charity and power during the (Counter) Revolution in the Journal of Nimes (1789-1790).

By examining the « charity » column in the Journal of Nimes, this article proposes to evoke the conceptions of the people held by upper class inhabitants of Nimes and the relationship between « rich » and « poor » that can be deduced during the first years of the French Revolution. The representation of the mayor, the Baron of Marguerittes, participates in the research of a consensus between moderates around a paternal figure, archetype of the charitable great man, thus confirming traditional social hierarchies. However, revolutionary innovations, around the practice of patriotic gifts and fiscal changes, divided the elites. They broke apart the research for a social refoundation and left the place open to radical political projects.

Published: March 2015

Premise of the study:

Microsatellite markers were developed for Carallia brachiata to assess the genetic diversity and structure of this terrestrial species of the Rhizophoraceae.

Methods and Results:

Based on transcriptome data for C. brachiata, 40 primer pairs were initially designed and tested, of which 18 were successfully amplified and 11 were polymorphic. For these microsatellites, one to three alleles per locus were identified. The observed and expected heterozygosities ranged from 0 to 0.727 and 0 to 0.520, respectively. In addition, all primers were successfully amplified in two congeners: C. pectinifolia and C. garciniifolia.

Conclusions:

The microsatellite markers described here will be useful in population genetic studies of C. brachiata and related species, suggesting that developing microsatellite markers from next‐generation sequencing data can be efficient for genetic studies across this genus.
Nine genera of Eucnemidae (Coleoptera) new to Peru, with a key to Peruvian genera
Authors: Vahtera Varpu , Muona Jyrki , Linna Ari , Sääksjärvi Ilari
Published: March 2015

Thirteen genera of Eucnemidae containing forty species were collected from the Iquitos region in Peru. Nine of the genera are new to the country: Rhagomicrus Fleutiaux, 1902, Adelorhagus Horn, 1890, Adelothyreus Chevrolat, 1867, Microrhagus Dejean, 1833, Dyscharachthis Blackburn, 1900, Heterotaxis Bonvouloir, 1871, Spinifornax Fleutiaux, 1926, Serrifornax Fleutiaux, 1926 and Maelodrus Fleutiaux, 1928. The previous eucnemid record from Peru contained eleven species in ten genera. Only one of the forty species caught, Entomophthalmus americanus Bonvouloir, was previously known and described from the country. Dyscharachthis, Maelodrus and Adelorhagus are recorded from South America for the first time. Many of the collected species seem to favor white-sand forest as their habitat. Possible reasons for this are discussed. A list of eucnemids from Peru is included, containing taxa already recorded from the country and also taxa that are likely to occur there. A key to the Peruvian genera is included.

Published: March 2015

This article compares various characteristics, including demographics, comorbid conditions, hospital status, and outcomes, in patients with major depression who received electroconvulsive therapy (ECT) versus those who did not. It seeks to determine if dyslipidemia is an indicator for ECT among patients hospitalized for depression. Data from all patients admitted to US hospitals between 2009 and 2010 with a primary discharge diagnosis of depression were included. We compared patients with depression who received ECT with those who did not. A logistic regression analysis was used to identify the association between patient and hospital characteristics and odds of receiving ECT. All variables that were significant in the univariate analysis were added as predictor variables to the stepwise logistic regression model. A total of 925,060 patients with depression were included. Of these, 20,251 (2.2%) underwent ECT. In the stepwise logistic regression, female gender (odds ratio [OR] 1.3, 95% confidence interval [CI] 1.2–1.5), white ethnicity (OR 1.8, 95% CI 1.2–2.5), and dyslipidemia (OR 1.3, 95% CI 1.0–1.6) were associated with receiving ECT among the patients with major depression. Large-sized hospitals (OR 1.9, 95% CI 1.2–2.9) and teaching hospitals (OR 3.2, 95% CI 2.1–4.8) were more likely to use ECT.[Psychiatr Ann.2015;45(3):140–144.]

Published: March 2015

PURPOSE:

To evaluate and compare the mechanical properties of anterior capsule opening performed with femtosecond laser capsulotomy at different energy settings in ex vivo porcine anterior lens capsule specimens.

METHODS:

Twenty-five fresh porcine eyes per group were included in the study. Femtosecond laser capsulotomy was performed with three different pulse energy levels: 2
µ
J (low energy group), 5
µ
J (intermediate energy group), and 10
µ
J (high energy group). The capsule openings were stretched with universal testing equipment until they ruptured. The morphologic profile of the cut capsule edges was evaluated using scanning electron microscopy.

RESULTS:

The high energy group had significantly lower rupture force (108 ± 14 mN) compared to the intermediate energy group (118 ± 10 mN) (
P
< .05) and low energy group (119 ± 11 mN) (
P
< .05), but the difference between the intermediate energy and low energy groups was not significant (
P
= .9479). The high energy group had significantly lower circumference stretching ratio (144% ± 3%) compared to the intermediate energy group (148% ± 3%) (
P
< .05) and low energy group (148% ± 3%) (
P
< .05), but the difference between the intermediate energy group and low energy group was not significant (
P
= .9985). Scanning electron microscopy images showed that the edge was only serrated with low and intermediate energy, but additional signs of collagen melting and denaturation were observed at high energy.

CONCLUSIONS:

Anterior capsule openings created at a high energy level were slightly weaker and less extensible than those created at low or intermediate levels, possibly due to the increased thermal effect of photo-disruption.

Repeatability and Inter-device Agreement for Three Different Methods of Keratometry: Placido, Scheimpflug, and Color LED Corneal Topography
Authors: Hidalgo Irene Ruiz , Rozema Jos J. , Dhubhghaill Sorcha Ní , Zakaria Nadia , Koppen Carina , Tassignon Marie-José
Published: March 2015

PURPOSE:

To determine the repeatability of a color LED corneal topographer (Cassini; iOptics, The Hague, The Netherlands) and compare it with Placido and Scheimpflug based devices (EyeSys 2000; EyeSys Laboratories, Houston, TX, and Pentacam HR; Oculus Optikgeräte GmbH, Wetzlar, Germany).

METHODS:

This prospective study involved 20 healthy volunteers (20 eyes) recruited from the staff of the Antwerp University Hospital. For each eye, three measurements were taken using each device, from which eight parameters describing keratometry and astigmatism were derived. Repeatability was assessed using intrasession, within-subject analysis of variance. Agreement was evaluated between pairs of devices with Bland– Altman plots and 95% confidence intervals.

RESULTS:

The repeatability values were good for all three devices, although slightly worse for the Cassini than for the other two devices for steep, flat, and mean keratometry. The EyeSys showed worse repeatability for the astigmatism axis. EyeSys and Pentacam agreed well with each other in terms of mean keratometry, whereas the Cassini gave consistently higher values by 0.52 diopters (D) when compared with the EyeSys (
P
< .05, paired
t
test) and by 0.38 D when compared with the Pentacam (
P
< .05, paired
t
test). The Cassini provided similar repeatability values (2.31°) for the astigmatism axis to the Pentacam (2.22°), in contrast to the EyeSys, which produced much more variable axes (9.0°) (
P
< .05, paired
t
test).

CONCLUSIONS:

Overall, the three devices display comparable repeatability. The one exception is the astigmatism axis measurement of the EyeSys. The Cassini provides higher keratometry values than the other two devices, but the astigmatism axis agrees well with that provided by the Pentacam.

Repeatability of Aberrometric Measurements With a New Instrument for Vision Analysis Based on Adaptive Optics
Authors: Otero Carles , Vilaseca Meritxell , Arjona Montserrat , Martínez-Roda Juan A. , Pujol Jaume
Published: March 2015

PURPOSE:

To evaluate intersession and intrasession repeatability of aberration data obtained with a new visual simulator based on adaptive optics, which includes a Hartmann-Shack aberrometer (Adaptive Optics Vision Analyzer; Voptica S.L., Murcia, Spain).

METHODS:

Thirty-one healthy right eyes were included in the study. To evaluate intrasession repeatability, three consecutive measurements without repositioning the patient or realigning the eye were obtained. Intersession repeatability was evaluated in three sessions. Aberrometric data computed from the second to the fifth order for a 4-mm pupil were used. Statistical analysis included the repeated measures analysis of variance (or the Wilcoxon signed rank test), the coefficient of repeatability, the Bland–Altman method, and the intraclass correlation coefficient.

RESULTS:

No significant differences in the intrasession and intersession repeatability analysis for any of the parameters (
P
> .05) were found, suggesting a consistent variability of the instrument over time. Similar coefficient of repeatability values were obtained in the three sessions. The Bland–Altman analysis confirmed differences close to zero and the variations were independent of the mean within and between sessions. The intersession intraclass correlation coefficient values were generally above 0.75, suggesting moderate to high repeatability. However, some exceptions were found in the intrasession analysis.

CONCLUSIONS:

The findings suggest that the new instrument provides consistent and repeatable aberrometric data. It is therefore a suitable tool to perform consistent and repeatable visual simulations.

Anterior Capsule Contraction Treated by Femtosecond Laser Capsulotomy
Authors: Schweitzer Cedric , Tellouck Laury , Gaboriau Thibaut , Leger François
Published: March 2015

PURPOSE:

To describe a new method to treat severe anterior capsule contraction using a femtosecond laser anterior capsulotomy.

METHODS:

Case report.

RESULTS:

A 48-year-old woman with a history of myotonic dystrophy experienced a severe contraction of the anterior capsule following an uneventful phacoemulsification cataract surgery with a hydrophilic acrylic intraocular lens implanted in the capsular bag. A femtosecond laser anterior capsulotomy was performed using a non-applanating fluid-filled interface. The spectral-domain optical coherence tomography imaging system associated with the laser enabled precise centration and location of the capsulotomy with a posterior cut located between the anterior surface of the intraocular lens and the anterior capsule inner surface. The free-floating capsulotomy was easily removed after the laser procedure, and 8 days postoperatively visual acuity recovered and myopic shift regressed with an intraocular lens centered in the capsular bag.

CONCLUSIONS:

Femtosecond laser assisted by a high-resolution imaging system appears to be a safe and efficient treatment for severe anterior capsule contraction.

Femtosecond Laser-Assisted Cataract Surgery After Implantation of a Transparent Near Vision Corneal Inlay
Authors: Parkhurst Gregory D. , Garza Enrique Barragan , Medina Arthur A.
Published: March 2015

PURPOSE:

To describe two cases of successful femtosecond laser-assisted cataract surgery in patients with a transparent hydrogel corneal inlay (Raindrop Near Vision Inlay; ReVision Optics, Inc., Lake Forest, CA).

METHODS:

Case report.

RESULTS:

In both cases, femtosecond laser-assisted cataract surgery was performed with the inlay in place. The femtosecond laser pulses were delivered without difficulties, and the Raindrop inlay did not interfere with the visualization of intraocular structures during surgery. Following implantation of a monofocal intraocular lens targeted for plano, both patients experienced improvements in their uncorrected distance visual acuity and regained near vision.

CONCLUSIONS:

These two cases suggest that the presence of the Raindrop inlay left in situ does not preclude successful femtosecond laser-assisted cataract surgery.

Research on Fuzzy-PID Temperature Control System for Double Helix Resistor
Authors: Wang Yun Jing , Dong Xian Ying , Qu Zheng Wei
Published: March 2015

Double Helix Resistor (DHR) can be used to establish AC resistance standard. Because the short-term stability of the DHR is very important during the process of quantity value dissemination, the DHR should be kept in a temperature-controlled environment. This paper presents a Fuzzy-PID temperature control method based on MSP430F149, the overshoot and adjustment time of the temperature control system can be reduced by using the Fuzzy control rules to adjust PID parameters. A special resistance box is designed to place DHR and decrease the exterior EMI effectively. At last, Fluke 8508A is used to measure the resistance of DHR. The measurement results show that the short-time relative stability of DHR is enhanced to 3×10-7after applying the presented temperature control system.
Millimeter Wave Characterization of Wire Bond Transitions for W-Band Electromagnetic Sensor
Authors: Fang Yong , Zeng Bao Qing , Zhang Wen Tao , Wang Pu
Published: March 2015

This paper presents millimeter wave characterization and models of various wire bond transitions between chip’s ground-signal-ground pad (GSG) and microstrip (MS), include single-wire-nomatch MS-GSG transition, double-wire-nomatch MS-GSG, single-wire-match MS-GSG transition, and double-wire-match MS-GSG transition. It also presents the 3D full-wave electromagnetic simulation. Analysis results show that the double-wire-match MS-GSG transition’s characteristic is better than other three transitions in the whole W band. The accurate extracted parameter values are used for the lumped equivalent circuit model, whose simulation results are good with the full wave simulation results. The error between lumped equivalent circuit and full-wave models is of the order of ±0.2dB for S11 and S21 in the frequency range 75 - 105GHz. The proposed lumped equivalent circuit is suitable to be implemented in commercial microwave CAD tools for the electromagnetic sensor designing.

Authors: Huang Sheng Bo , Wen Yu Cang , Ye Wen , Fan Tong Liang
Published: March 2015

OFDM usually incorporates pilot tones in the frequency domain (FD) or training symbols in the time-domain (TD) to facilitate channel estimation algorithms. TD channel estimation becomes more attractive in quasi-static channels because channel estimation scheme will optimize the spectral efficiency by re-using the training symbols designated for FD channel estimation. A channel estimation method based on time domain averaging algorithm is proposed. Due to the principle of centralized energy in time domain, the effective channel impulse response length can be detected by setting of threshold for the estimated channel impulse response length. Computer simulation demonstrates the performance of the proposed algorithms in terms of bit error rate performance.
