Scene changes with plastic visual rhymes
Authors: Hinterwaldner Inge 
Published: May 2014

Abstract
In 1946, the surrealist artist Salvador Dalí was given the opportunity to realize an animation called Destino in cooperation with Walt Disney. The painter was highly motivated to explore different kinds of smooth transitions between the scenes. For Dalí, this was a way to further develop his already elaborated method of polyvalent ‘double images’ by enhancing it with explicit dynamics. A short typology of the different alternatives to the hard cut that Dalí envisioned is given here. The key aspects are anamorphosis, transmigration of forms, metamorphosis, figure/ground-reversal and change in reaction. The Japanese artist Tabaimo shares several iconographic motifs, as well as formal solutions, with Dalí. With her animation installation teleco-soup, it can be shown that astonishingly small pictorial interventions into a scene suffice to completely transform the interpretation, spatial suggestion and the way the beholder is located in relation to the image. Although objectively the scene remains similar, a great deal changes at once. Therefore, these ‘visual rhymes’ can be considered as condensed, elegant and surprising forms of expression.
Ferrier–Nicholas pyranosidic cations: application to diversity-oriented synthesis
Authors: Lopez J. Cristobal , Lobo Fernando , Miranda Silvia , Uriel Clara , Gomez Ana M. 
Published: May 2014

AbstractPyranosidic allylic (Ferrier) cations that share dicobalt hexacarbonyl propargyl (Nicholas) stabilization at C-1, can be easily generated by treatment of hexacarbonyldicobalt alkynyl glycals with BF3·OEt2, and display a remarkable reactivity leading to a variety of products. The substituent at O-6 in these glycals plays a pivotal role in directing the outcome of the transformations. Accordingly, 6-O-benzyl or 6-O-allyl groups cause a series of transformations resulting in the stereoselective formation of oxepanes through a process that involves an initial hydride transfer step from the allyl or benzyl substituent to the Ferrier–Nicholas cation. On the contrary, 6-OH derivatives undergo an overall ring contraction to branched tetrahydrofuran derivatives. 6-O-Silyl derivatives, in the presence of heteroaryl nucleophiles, were transformed into C-3 branched bis-C-C-glycosides, containing two of such molecules.

Published: May 2014

ABSTRACTOutstanding information about the material composition and pictorial techniques of the New Spain Colonial painting can be obtained via a full characterization using a set of analytical techniques. Given the cultural importance of this painting, a non-invasive approach is preferred. Moreover, the preparation and use of reference materials using original recipes is necessary for a correct interpretation of the spectroscopic data from historical objects. Here, we present the results obtained via an in-situ Raman spectroscopic analysis of a set of pictorial reference materials, created according to XVI and XVII centuries’ recipes. Several difficulties were encountered, such as the low Raman detection signal, an intrinsic fluorescence of the material, and in some cases even laser-induced degradation. For this reason, the usual molecular Raman analysis was extended to Surface Enhanced Raman Spectroscopy (SERS), which enhances the Raman signal and quenches the fluorescence. It was then applied to the analysis of two wood paintings from the ex-convent San Francisco Tepeyanco, in Tlaxcala.

OBJECTIVE
To determine whether impaired awareness of hypoglycemia (IAH) can be improved and severe hypoglycemia (SH) prevented in type 1 diabetes, we compared an insulin pump (continuous subcutaneous insulin infusion [CSII]) with multiple daily injections (MDIs) and adjuvant real-time continuous glucose monitoring (RT) with conventional self-monitoring of blood glucose (SMBG).

RESEARCH DESIGN AND METHODS
A 24-week 2 × 2 factorial randomized controlled trial in adults with type 1 diabetes and IAH was conducted. All received comparable education, support, and congruent therapeutic targets aimed at rigorous avoidance of biochemical hypoglycemia without relaxing overall control. Primary end point was between-intervention difference in 24-week hypoglycemia awareness (Gold score).

RESULTS
A total of 96 participants (mean diabetes duration 29 years) were randomized. Overall, biochemical hypoglycemia (≤3.0 mmol/L) decreased (53 ± 63 to 24 ± 56 min/24 h; P = 0.004 [t test]) without deterioration in HbA1c. Hypoglycemia awareness improved (5.1 ± 1.1 to 4.1 ± 1.6; P = 0.0001 [t test]) with decreased SH (8.9 ± 13.4 to 0.8 ± 1.8 episodes/patient-year; P = 0.0001 [t test]). At 24 weeks, there was no significant difference in awareness comparing CSII with MDI (4.1 ± 1.6 vs. 4.2 ± 1.7; difference 0.1; 95% CI −0.6 to 0.8) and RT with SMBG (4.3 ± 1.6 vs. 4.0 ± 1.7; difference −0.3; 95% CI −1.0 to 0.4). Between-group analyses demonstrated comparable reductions in SH, fear of hypoglycemia, and insulin doses with equivalent HbA1c. Treatment satisfaction was higher with CSII than MDI (32 ± 3 vs. 29 ± 6; P = 0.0003 [t test]), but comparable with SMBG and RT (30 ± 5 vs. 30 ± 5; P = 0.79 [t test]).

CONCLUSIONS
Hypoglycemia awareness can be improved and recurrent SH prevented in long-standing type 1 diabetes without relaxing HbA1c. Similar biomedical outcomes can be attained with conventional MDI and SMBG regimens compared with CSII/RT, although satisfaction was higher with CSII.
Potentiometric Oxygen Sensor with Solid State Reference Electrode

Published: May 2014

Abstract
The concentration or the partial pressure of oxygen in an environment can be determined using different measuring principles. For high temperature measurements of oxygen, ceramic-based sensors are the most practical. They are simple in construction, exploration and maintenance. A typical oxygen potentiometric sensor consists of an oxygen ion conducting solid electrolyte and two electrodes deposited on the two sides of the electrolyte. In this paper different structures of potentiometric oxygen sensors with a solid state reference electrode were fabricated and investigated. The fabricated structures consisted of oxygen ion conducting solid electrolyte from yttria stabilized zirconia, a sensing platinum electrode and nickel-nickel oxide reference electrode. The mixture of nickel-nickel oxide was selected as the reference electrode because it provides reliable electrochemical potential in contact with oxygen conducting electrolyte. To avoid oxidation of nickel the reference electrode is sealed from ambient and the mixture of nickel-nickel oxide was formed electrochemically from nickel oxide after sealing. The effectiveness of the sealing quality and the effectiveness of nickel-nickel oxide mixture formation was investigated by impedance spectroscopy.

Published: May 2014

Abstract
This article presents the validation process of a brake FE model by means of temperature measured on a special stand using infrared technology. Unlike many other publications, the authors try to show the interaction between measurement technology and numerical modeling rather than only nice, perfectly correlated graphs. Some difficulties in choosing and using validation parameters are also pointed out and discussed. Finally, results of FE analyses are compared with measured data, followed by explanation of applied numerical technology and estimation of validation process effectiveness.

Published: May 2014

Abstract
The objective of the study was to determine properties of soils located within a city, and to assess the effect of anthropopressure on the accumulation of carbon and nitrogen in soils of Pruszków . a medium sized town in central Poland. Surface soil layers (0.20 cm) were collected at 36 sites. A total of 12 samples from lawns, 11 from allotment gardens, 9 from fields and 4 from fallow lands were subject to analysis. Lawns and allotment gardens were treated as central zone I . under strong pressure of anthropogenic factors, fields and fallow lands were treated as zone II . with potentially low level of anthropogenic influence. The statistical analysis showed significantly higher (p=0.008) amount of organic carbon (Corg) in lawns (mean 20.5 g·kg-1) and allotment gardens (21.7 g·kg-1) . zone I, than on fallow lands (10.4 g·kg-1) and fields (1.27 g·kg-1) . zone II. The surface layer of soil from allotment gardens also contained significantly higher amount of total nitrogen (mean content 1.1 g·kg-1) than others. The amounts of Corg not depending on the soil texture and very high C/N ratio, suggests the anthropogenic origin of the carbon. The C/N ratio was the highest in the soils of lawns (mean value 26.2) and significantly differed (p=0.04) from C/N ratios in soils of fields and allotment gardens. This suggests low intensity of humus transformation. Other chemical characteristics as hydrolytic acidity (Ha), cation exchange capacity (CEC), exchangeable base cations (EBC) and EBC share in CEC were also higher in central part of Pruszków town (zone I), indicating the effect of urbanization on soil properties.
Postoperative Mycoplasma hominis infections after neurosurgical intervention
Authors: Whitson Wesley J. , Ball Perry A. , Lollis S. Scott , Balkman Jason D. , Bauer David F. 
Published: May 2014

Object
Mycoplasma hominis is a rare cause of infection after neurosurgical procedures. The Mycoplasma genus contains the smallest bacteria discovered to date. Mycoplasma are atypical bacteria that lack a cell wall, a feature that complicates both diagnosis and treatment. The Gram stain and some types of culture media fail to identify these organisms, and typical broad-spectrum antibiotic regimens are ineffective because they act on cell wall metabolism. Mycoplasma hominis commonly colonizes the genitourinary tract in a nonvirulent manner, but it has caused postoperative, postpartum, and posttraumatic infections in various organ systems.
The authors present the case of a 17-year-old male with a postoperative intramedullary spinal cord abscess due to M. hominis and report the results of a literature review of M. hominis infections after neurosurgical procedures. Attention is given to time to diagnosis, risk factors for infection, ineffective antibiotic regimens, and final effective antibiotic regimens to provide pertinent information for the practicing neurosurgeon to diagnose and treat this rare occurrence.

Methods
A PubMed search was performed to identify reports of M. hominis infections after neurosurgical procedures.

Results
Eleven cases of postneurosurgical M. hominis infection were found. No other cases of intramedullary spinal cord abscess were found. Initial antibiotic coverage was inadequate in all cases, and diagnosis was delayed in all cases. Multiple surgical interventions were often needed. Once appropriate antibiotics were started, patients typically experienced rapid resolution of their neurological symptoms. In 27% of cases, a suspicious genitourinary source other than urinary catheterization was identified.

Conclusions
Postoperative M. hominis infections are rarely seen after neurosurgical procedures. They are typically responsive to appropriate antibiotic therapy. Mycoplasma infection may cause prolonged hospitalization and multiple returns to the operating room due to delay in diagnosis. Early clinical suspicion with appropriate antibiotic coverage could help prevent these significant complications.
L’espace public en partage. Expériences conflictuelles de l’espace et marginalisation
Authors: Margier Antonin 
Published: May 2014

L’exclusion dans les espaces publics est souvent interprétée comme le résultat de politiques urbaines revanchistes visant à attirer touristes et classes supérieures aux dépens des personnes marginalisées. Autour de l’analyse d’usages conflictuels de l’espace public dans un quartier montréalais, cet article explore l’hypothèse selon laquelle l’exclusion prendrait aujourd’hui de nouvelles formes. Dans cette perspective, nous nous intéressons aux conditions de l’investissement des positions sociospatiales et aux diverses expériences de l’espace, afin de saisir les mécanismes de l’exclusion dans les espaces publics. Nous montrons alors comment les stratégies d’appropriation des espaces publics par les riverains, et leur utilisation comme une extension du « chez-soi » participent d’une transformation des valeurs spatiales et de l’émergence d’une « dispersion douce » à l’encontre des personnes marginalisées. Cet article vise ainsi à montrer comment de nouvelles formes de pouvoir, moins visibles que le revanchisme ou la tolérance-zéro, se font jour dans la production des espaces publics, notamment à travers le contrôle des références topologiques.
Équité environnementale et distribution spatiale de la végétation à l’intérieur et autour des îlots résidentiels à Montréal : une double iniquité ?

Published: May 2014

De récentes études ont montré que la végétation urbaine est inégalement distribuée au sein de plusieurs métropoles nord-américaines : certains quartiers plus défavorisés ou à forte concentration ethnique présenteraient des niveaux de couverture végétale plus limités. L’objectif de cet article est de vérifier l’existence d’iniquités environnementales en termes d’accès à la végétation urbaine sur le territoire de l’ancienne ville de Montréal pour les personnes à faible revenu et les minorités visibles. Six indicateurs de végétation à l’intérieur et autour des îlots résidentiels (à 250 et 500 m) sont construits à l’aide d’images satellites QuickBird. Puis, ces indicateurs sont mis en relation avec des données socioéconomiques au moyen de plusieurs analyses statistiques (corrélation, test de Student (test t), analyse de variance et analyse de régression). Les résultats démontrent que la population à faible revenu et, dans une moindre mesure, celle des minorités visibles résident dans des environnements où la végétation est moins présente. Finalement, l’utilisation combinée d’indicateurs de végétation à l’intérieur et autour de l’îlot permet de démontrer l’existence d’une double iniquité dans certains secteurs urbains.
Mobilité et lutte contre la pollution atmosphérique
Authors: Gobert Julie 
Published: May 2014

Dans un but de développement économique des territoires, les pouvoirs publics sont amenés, en France, à favoriser le « capital mobilité » des individus pour leur donner le moyen d’accéder au marché du travail et à un ensemble de ressources et de services. Toutefois, il est également nécessaire de réguler les problèmes liés à l’automobilité et aux nuisances environnementales qui lui sont inhérentes. Les politiques publiques de transport ont de ce fait évolué : la notion de « droit à la mobilité » se dissout peu à peu au profit d’objectifs plus complexes de développement durable. Ce dilemme entre enjeux économiques, sociaux et environnementaux pose la question des inégalités environnementales, particulièrement quand il s’agit de mettre en place une zone à basse émission sur les grandes agglomérations, comme cela est prévu dans la loi du Grenelle II sous le nom de zone d’actions prioritaires pour l’air (ZAPA). Au regard d’une enquête de terrain menée sur une intercommunalité de Seine-Saint-Denis, en amont de la mise en place d’une ZAPA, nous avons cherché à mieux connaître l’impact d’une telle mesure et les possibles répercussions en termes d’inégalités.

AbstractFracture non‐union occurs due to various factors, leading to the development of potentially substantial bone defects. While autograft and allograft are the current gold standards for non‐union fractures, challenges related to availability and immune rejection highlight the need for improved treatments. A strategy in bone tissue engineering is to harness growth factors to induce an effect on cells to change their phenotype, behavior and initiate signaling pathways which lead to increased matrix deposition and tissue formation. Bone morphogenetic protein‐2 (BMP‐2) is a potent osteogenic growth factor however, given its rapid clearance time in vivo, there is a specific therapeutic window for efficacy while avoiding potential deleterious side‐effects. It is demonstrated that a Laponite nanoclay coating on a 3D printable and bioresorbable poly(caprolactone) trimethacrylate‐based resin enables binding of BMP‐2, decreases the rate of release, enabling reduced concentrations to be used while enhancing osteoinduction in both in vitro and in vivo models.

AbstractGallium Phosphide (GaP) has recently received considerable attention as a suitable material for building photonic integrated circuits due to its remarkable optical and piezoelectric properties. Usually, GaP is grown epitaxially on III–V substrates to keep its crystallinity and later transferred to silicon wafers for further processing. Here, an alternative promising route for the fabrication of optomechanical (OM) cavities on GaP epitaxially grown on nominally (001)‐oriented Si is introduced by using a two‐step process consisting of a low‐temperature etching of GaP followed by selective etching of the underneath silicon. The low‐temperature (–30 °C) during the dry‐etching of GaP hinders the lateral etching rate, preserving the pattern with a deviation between the design and the pattern in the GaP layer lower than 5%, avoiding the complex process of transferring and bonding a GaP wafer to a silicon‐on‐insulator wafer. To demonstrate the quality and feasibility of the proposed fabrication route, suspended OM cavities are fabricated and experimentally characterized. The cavities exhibit optical quality factors between 103 and 104 at telecom wavelengths, and localized mechanical resonances ≈3.1 GHz with quality factors ≈63 when measured at room temperature. These results suggest a simple and low‐cost way to build GaP‐based photonic devices directly integrated on industry‐standard Si(001) photonic wafers.

Published: July 2024

AbstractChemodynamic therapy (CDT) is a novel tumor treatment method by using hydroxyl radicals (•OH) to kill cancer cells. However, its therapeutic effects are strictly confined by the short lifespan of •OH and reduced •OH generation speed. Herein, an effective CDT is achieved by both improving •OH lifetime and long‐lasting generating •OH through intraparticle electron transfer within heterogeneous nanoparticles (NPs). These heterogeneous NPs are composed of evenly distributed Cu and Fe3O4 (CFO NPs) with large interaction interfaces, and electrons tend to transfer from Cu to Fe3O4 for the appearance of ≡Cu2+ and increase in ≡Fe2+. The generated ≡Cu2+ can interact with GSH, which prolongs the lifespan of •OH, produces ≡Cu+ for higher speed •OH generation with H2O2, and induces cell ferroptosis for tumor therapy. The improved ≡Fe2+ can also improve the •OH release under H2O2 until Cu is depleted. As a result, a sustainable •OH generation is achieved to promote cell apoptosis for effective tumor therapy. Since H2O2 and GSH are only overexpressed at tumor, and CFO NPs can degrade in the tumor microenvironment, these NPs are with high biosafety and can be metabolized by urine. This work provides a novel biomaterial for effective cancer CDT through intraparticle electron transfer.

AbstractIn this paper, a direct access to benzylic amines from in‐situ generated ortho‐quinone methides (o‐QMs) and isocyanate/isothiocyanate via decarboxylation is described. This base‐catalyzed methodology has high functional group tolerance and shows a wide range of substrate scopes, where H2O as a nucleophile for isocyanate/isothiocyanate for product formation. The products are insensitive to air and moisture, which makes this synthetic strategy more efficient for the construction of various benzyl amine derivatives.
