Object
The aim of this study was to evaluate the clinical results and surgical outcomes of cystic vestibular schwannomas (VSs) with fluid-fluid levels.

Methods
Forty-five patients with cystic VSs and 86 with solid VSs were enrolled in the study. The patients in the cystic VSs were further divided into those with and without fluid-fluid levels. The clinical and neuroimaging features, intraoperative findings, and surgical outcomes of the 3 groups were retrospectively compared.

Results
Peritumoral adhesion was significantly greater in the fluid-level group (70.8%) than in the nonfluid-level group (28.6%) and the solid group (25.6%; p < 0.0001). Complete removal of the VS occurred significantly less in the fluid-level group (45.8%, 11/24) than in the nonfluid-level group (76.2%, 16/21) and the solid group (75.6%, 65/86; p = 0.015). Postoperative facial nerve function in the fluid-level group was less favorable than in the other 2 groups; good/satisfactory facial nerve function 1 year after surgery was noted in 50.0% cases in the fluid-level group compared with 83.3% cases in the nonfluid-level group (p = 0.038).

Conclusions
Cystic VSs with fluid-fluid levels more frequently adhered to surrounding neurovascular structures and had a less favorable surgical outcome. A possible mechanism of peritumoral adhesion is intratumoral hemorrhage and consequent inflammatory reactions that lead to destruction of the tumor-nerve barrier. These findings may be useful in predicting surgical outcome and planning surgical strategy preoperatively.
The effect of screw head design on rod derotation in the correction of thoracolumbar spinal deformity
Authors: Lam Fred C. , Groff Michael W. , Alkalay Ron N. 
Published: July 2013

Object
The use of fixed-axis pedicle screws for correction of thoracolumbar deformity in adult surgery is demanding because of the challenge of assembling the bent rod to the screw in order to achieve curve correction. Polyaxial screw designs, providing increased degrees of freedom at the screw-rod interface, were reported to be insufficient in achieving correction of thoracic deformity in the axial plane. Using a multisegment bovine calf spine model, this study investigated the ability of a new uniplanar screw design to achieve derotation correction of the vertebrae and maintain a degree of correction comparable to that of fixed-axis and polyaxial screw designs.

Methods
Eighteen calf thoracolumbar spine segments from T-6 to L-1 (n = 6 per screw design) underwent bilateral facetectomies at the T9–11 levels and were instrumented bilaterally with pedicle screws and rods. To assess the efficacy of each screw design in imparting rotational correction, each instrumented level was tested under applied torsional moments designed to simulate the motion applied during derotation surgery. Once rotation was achieved, the whole spine was tested to assess the overall stiffness of the construct.

Results
The fixed-axis construct showed increased efficacy in imparting rotation compared with the uniplanar (115% increase, p > 0.05) and polyaxial (210% increase, p < 0.05) constructs. Uniplanar screws showed a 21% increase in torsional stiffness compared with the polyaxial screws, but this difference was not statistically significant.

Conclusions
The design of screw heads plays a significant role in affecting the rotation of the vertebrae during the derotation procedure. Uniplanar screws may have the advantage of maintaining construct stiffness after derotation.

Saint-Quentin in Troyes : eine wiederentdeckte romanische Kirche, von Thomas Spencer
In der Rue Mitantier in Troyes steht ein Gebäude, das sich äußeilich nicht von den umgebenden Bauten unterscheidet ; es handelt sich jedoch um die ehemalige Kirche Saint-Quentin. Dieses Denkmal ist im Schatten der Stadtgeschichte untergetaucht und die heutigen Einwohner von Troyes rechnen gar nicht mehr mit seiner Existenz.
Nach der Überlieterung wurde die Kirche im 7. Jahrhundert gegründet, in einer Zeit starker Missionstatigkeit in der Champagne. Schriftliche Quellen des 12. Jahrhunderts weisen darauf hin, dass die Kirche Saint-Quentin Ende des 11 . Jahrhunderts durch den Grafen Thibaud I. von Champagne der Abtei Molesme geschenkt wurde. Der Fortgang ihrer Geschichte ist heute weitgehend unbekannt, bis auf einige wenige Intormationen ans neuzeitlichen Quellen. Im Gegensatz zu vielen anderen religiösen Bauwerken ist die Kirche Saint-Quentin zu Troyes der Zerstorung durch die Französische Revolution entgangen. Sie wurde verkauft und diente bis in die 1920er Jahre zu industriellen Zwecken. In den 1950er Jahren ging sie in den Besitz der Stadt Troyes über, aber sie hat niemals eine neue Bestimmung erhalten.
Eine jüngere architektonische Untersuchung hat gezeigt, dass das Bauwerk größtenteils ans Resten besteht, die in die Zeit zwischen 1075 und 1150 datieren, trotz aller späteren Umwandlungen. Es existieren noch zahlreiche bildhauerische Elemente und geben einen Eindruck von den Zum Teil aufsergewöhnlichen Themen und dem Talent der romanischen Bildhauer, die in Frayes tätig waren. Diese Kirche ist von großem Interesse für die Untersuchung sowohl der Bautechniken, als auch der Bauplastik in einer Stadt, in der die Epoche der Romanik fast keine Spuren im aktuellen Stadtbild hinterlassen hat.
Vision et Narcissisme
Authors: Putois Olivier 
Published: July 2013

Nous diagnostiquons critique lacanienne du dernier Merleau-Ponty le refus d’une identification du visible à l’image d’un sens suivant lequel le sujet pourrait le reconnaître (narcissisme charnel). Le stade du miroir montre au contraire qu’aucune image – même celle, spéculaire, du corps propre –, n’a de valeur représentative tant qu’elle ne reçoit pas son sens inconscient par une réponse signifiante proférée au lieu de l’Autre ; et que, corrélativement, le primat d’une telle réponse signifiante opacifie l’image, en mettant en évidence l’absence de sens immanent qui découle de son conditionnement diacritique. La fascination schizophrénique pour l’image spéculaire caractéristique du signe du miroir confirme a contrario le primat d’une telle réponse, en manifestant la dépersonnalisation que produit son absence ; elle permet ainsi d’invalider cliniquement la thèse merleau-pontyenne.
Is the Gain in Psychoanalysis a Grain of Time, the Object “a” in “-”?
Authors: Lenoir Olivier , Poggi Paul 
Published: July 2013

Le gain de la psychanalyse est-il un grain de temps, l’objet « a » en « - » ? Formaliser un gain pour la psychanalyse n’est-il pas aujourd’hui un enjeu ? Le gain n’est-il pas alors un lien que la psychanalyse peut faire entre un formalisme comme celui d’un modèle macroéconomique avec une possible dynamique du sujet. Nous partirons de cette idée de gain pour réexaminer, sous l’angle du jeu notamment, le pari pascalien vers une articulation logique de la rencontre clinique.

Three new metal-organic frameworks based on Zn2+ and 1,4-diazoniabicyclo[2.2.2]octane-1,4- diacetate () were synthesized and fully characterized by single-crystal X-ray diffraction and other methods. The linker L provides both positively charged quaternary ammonium centers and a flexible methylene chain, which brings conformational diversity to the system. The same reactants, and the same preparation procedures were used for the syntheses of ZnLCl2 (1), ZnL
2(NO3)(OH)·(DMF)·(H2O) (2) and ZnL
3(NO3)2(H2O) (3), to study the role of solvents and anions during the synthesis. All three MOFs show one-dimensional networks with different topologies. Closed loops with different ring sizes could be found in 2and 3along the chain. Rings with 22 atoms were found in 2, while the smallest loop in 3contains 44 atoms, including four linkers and four zinc atoms. Clearly, the solvent, stoichiometries of the reactants, and the anions had an impact on the formation of the three distinct network structures.

The hydrothermal reactions of 5-(benzimidazol-1-ylmethyl)isophthalic acid (H2L) with Zn(II) and Cd(II) salts lead to the formation of the two new complexes [Cd(L)] (1) and [Zn(L)] (2). In the presence of 2-(pyridin-2-yl)-1H-benzimidazole (pybim) as auxiliary ligand, complex [Zn(L)(pybim)] (3) was obtained. Complexes 1-3have been characterized by single-crystal and powder X-ray diffraction, IR spectroscopy, and elemental and thermogravimetric analyses. Complexes 1and 2are isostructural and exhibit a binodal (3,6)-connected 2D network structure with (43)2(46.66.83) topology; 3 consists of uninodal 3-connected 2D (63) hcb networks. The influential factors of synthetic strategies on the coordination modes of the ligands and on the structures and properties of the resulting complexes are discussed. The luminescence properties of 1-3were investigated.

A Hollow‐Core Optical Cavity Built in a Three‐Layer Silicon Photonic Crystal

Published: July 2013

Hollow‐core (HC) optical microcavities differ from conventional ones in that they can strongly confine light in air. HC cavities simultaneously possessing high air–energy ratios (αair), high quality factors (Q), and small mode volumes (Veff) may enable on‐chip low‐concentration molecular sensing, high optical power delivery or storage, and low‐threshold optical oscillation or lasing when filled with materials of desirable nonlinearities. However, designing and fabricating such cavities has been challenging, especially when using only a small number of layers. Here, the design and fabrication of such an HC cavity in a three‐layer silicon photonic crystal (PhC) is reported. It supports a transverse magnetic (TM) cavity mode with αair ≈ 67% and Q ≈ 1.7 × 105 in the 1550 nm wavelength range. The in‐plane confinement is provided by the 2D photonic bandgap (PBG) of a dielectric rod array, while a pair of capping slabs with air–hole PhC patterns confine light in air in the vertical direction. The cavity allows detection of low‐concentration substances that induce refractive index changes as small as around 8.8 × 10−6. The proposed cavity design and its fabrication provide a new approach to three‐dimensional photonic confinement using a structure consisting of only a few layers.
Light Trapping with Dielectric Scatterers in Single‐ and Tandem‐Junction Organic Solar Cells
Authors: Tang Zheng , Elfwing Anders , Bergqvist Jonas , Tress Wolfgang , Inganäs Olle 
Published: July 2013

Efficient dielectric scatterers based on a mixture of TiO2 nanoparticles and polydimethylsiloxane are demonstrated for light trapping in semitransparent organic solar cells. An improvement of 80% in the photocurrent of an optimized semitransparent solar cell is achieved with the dielectric scatterer with ≈100% diffuse reflectance for wavelengths larger than 400 nm. For a parallel tandem solar cell, the dielectric scatterer generates 20% more photocurrent compared with a silver mirror beneath the cell; for a series tandem solar cell, the dielectric scatterer can be used as a photocurrent balancer between the subcells with different photoabsorbing materials. The power conversion efficiency of the tandem cell in series configuration with balanced photocurrent in the subcells exceeds that of an optimized standard solar cell with a reflective electrode. The characteristics of polydimethylsiloxane, such as flexibility and the ability to stick conformably to surfaces, also remain in the dielectric scatterers, which makes the demonstrated light trapping configuration highly suitable for large scale module manufacturing of roll‐to‐roll printed organic single‐ or tandem‐junction solar cells.
Squealing rate indicates dominance rank in the male ring‐tailed lemur (Lemur catta)
Authors: Bolt Laura M. 
Published: July 2013

AbstractSqueals are sharp and forceful short‐range vocalizations used as aggressive and submissive agonistic signals by many mammalian species. The ring‐tailed lemur (Lemur catta), a female‐dominant strepsirhine primate, has a male‐specific squeal call with proposed male–male agonistic functions and male–female courtship functions that have never been empirically tested. The goal of my study is to clarify why ring‐tailed lemur males squeal at other males and females by applying the handicap hypothesis to this male‐specific vocalization. This hypothesis has rarely been tested in primates, and this study elucidates how the rate of a male‐specific call relates to male–male and male–female behavior in a Malagasy strepsirhine. To test whether males squeal towards other males to assert dominance, I predict that male squealing rate is positively correlated with dominance rank. I further predict that male ring‐tailed lemurs squeal at other males while engaged in agonistic interactions, and that squealing during an interaction is positively correlated with winning that encounter. To test whether males squeal towards females as a mate attraction signal, I predict that male squealing rate is higher on estrus days, and that estrous females indicate attraction by approaching squealing males. From March to July 2010, 480 hr of focal data were collected on 25 males aged three and older at Beza Mahafaly Special Reserve, Madagascar. I continuously observed each male for 30 min at a time and recorded all agonistic interactions and squeal vocalizations using 1–0 sampling at 2.5‐min intervals. Squealing rate was higher during times of male–male agonism when compared to times without male–male agonism, and males with higher dominance ranks had higher squealing rates. In contrast, the mate attraction hypothesis was not supported. My results suggest that the male squeal is an agonistic signal when used in male–male interaction in ring‐tailed lemurs, but does not specifically indicate aggression or submission. Am. J.

ABSTRACTThe male dispersal patterns of western lowland gorillas (WLGs,Gorilla gorilla gorilla) are not well understood. To determine whether most silverbacks stay close to their relatives, we analyzed autosomal and Y‐chromosomal microsatellites (STRs) in wild WLGs at Moukalaba, Gabon. We obtained STR genotypes for 38 individuals, including eight silverbacks and 12 adult females in an approximately 40 km2area. Among them, 20 individuals were members of one identified group (Group Gentil; GG), including one silverback and six adult females. The silverback sired all 13 of the offspring in GG and no Y‐STR polymorphism within GG was found, as expected in a one‐male group structure. Over all silverbacks sampled, Y‐STR diversity was high considering the limited sampling area, and silverbacks with similar Y‐STR haplotypes were not always located in nearby areas. Although the misclassification rate of kinship estimates in this study was not negligible, there were no kin dyads among all silverbacks sampled. These results suggest that silverbacks born in the same group do not stay close to each other after maturation. The Y‐STR diversity in this study was similar to that of a previous study conducted in an area that was approximately 150 times larger than our study area. Similarity of WLG Y‐STR diversity between studies at different sampling scales suggests that male gene flow may not be geographically limited. These results suggest that WLG males normally disperse from their natal areas after maturation, at least, in Moukalaba. Am J Phys Anthropol 151:583–588, 2013. © 2013 Wiley Periodicals, Inc.
Manifestations of Non‐Planar Adsorption Geometries of Lead Pyrenocyanine at the Liquid‐Solid Interface
Authors: Mali Kunal S. , Zöphel Lukas , Ivasenko Oleksandr , Müllen Klaus , De Feyter Steven 
Published: July 2013

AbstractIn this work, we provide evidence for multiple non‐planar adsorption geometries of a novel pyrenocyanine derivative at the liquid–solid interface under ambient conditions. When adsorbed at the organic liquid–solid interface, lead pyrenocyanine forms well‐ordered monolayers that exhibit peculiar non‐periodic contrast variation. The different contrast of the adsorbed molecules is attributed to dissimilar adsorption geometries which arise from the non‐planar conformation of the molecules. The non‐planarity of the molecular backbone in turn arises due to a combination of the angularly extended pyrene subunits and the presence of the large lead ion, which is too big to fit inside the central cavity and thus is located out of the aromatic plane. The two possible locations of the lead atom, namely below and above the aromatic plane, could be identified as depression and protrusion in the central cavity, respectively. The manifestation of such multiple adsorption geometries on the structure of the resultant monolayer is discussed in detail. The packing density of these 2D arrays of molecules could be tuned by heating of the sample wherein the molecular packing changes from a low‐density, pseudo six‐fold symmetric to a high‐density, two‐fold symmetric arrangement. Finally, a well‐ordered two‐component system could be constructed by incorporating C60 molecules in the adlayer of lead pyrenocyanine at the liquid–solid interface.
Knowledge and periconceptional use of folic acid for the prevention of neural tube defects in ethnic communities in the United Kingdom: Systematic review and meta‐analysis
Authors: Peake Jordana N. , Copp Andrew J. , Shawe Jill 
Published: July 2013

BACKGROUNDIt is widely accepted that periconceptional supplementation with folic acid can prevent a significant proportion of neural tube defects (NTDs). The present study evaluated how folic acid knowledge and periconceptional use for NTD prevention varies by ethnicity in the United Kingdom (U.K.).METHODSA literature search was conducted to identify studies that included assessment of folic acid knowledge or use in U.K. women of different ethnicities. Only research and referenced sources published after 1991, the year of the landmark Medical Research Council's Vitamin Study, were included. A meta‐analysis was performed of studies that assessed preconceptional folic acid use in Caucasians and non‐Caucasians.RESULTSFive studies met the inclusion criteria for assessment of knowledge and/or use of folic acid supplements in U.K. women including non‐Caucasians. The available evidence indicates that South Asians specifically have less knowledge and lower periconceptional use of folic acid than Caucasians; one study found that West Indian and African women also had lower folic acid uptake. A synthesis of results from three of the studies, in a meta‐analysis, shows that Caucasians are almost three times more likely to take folic acid before conception than non‐Caucasians.CONCLUSIONFrom the limited evidence available, U.K. women of non‐Caucasian ethnicity appear to have less knowledge and a lower uptake of folic acid supplementation than Caucasians during the periconceptional period. Implementing targeted, innovative education campaigns together with a mandatory fortification policy, including the fortification of ethnic minority foods, will be required for maximum prevention of folic acid–preventable NTDs across different ethnic groups.

Published: July 2013

ABSTRACTIn this study, a series of LaNbTiO6:RE3+ (RE = Tb, Dy, Ho) down‐converting phosphors were synthesized using a modified sol–gel combustion method, and their photoluminescence (PL) properties were investigated as a function of activator concentration and annealing temperature. The resultant particles were characterized using X‐ray diffraction, transmission electron microscopy, scanning electron microscopy, UV/Vis diffuse reflectance spectroscopy and PL spectra. The highly crystalline LaNbTiO6:RE3+ (RE = Tb, Dy, Ho) phosphors with an average size of 200–300 nm obtained at 1100°C have an orthorhombic aeschynite‐type structure and exhibit the highest luminescent intensity in our study range. The emission spectra of LaNbTiO6:RE3+ (RE = Tb, Dy, Ho) phosphors under excitations at UV/blue sources are mainly composed of characteristic peaks arising from the f–f transitions of RE3+, including 489 nm (5D4 → 7F6) and 545 nm (5D4 → 7F5) for Tb3+, 476 and 482 nm (4F9/2 → 6H15/2) and 571 nm (4F9/2 → 6H13/2) for Dy3+, and 545 nm (5F4 + 5S2 → 5I8) for Ho3+, respectively. The luminescent mechanisms were further investigated. It can be expected that these phosphors are of intense interest and potential importance for many optical applications.
