The threshold photoelectron (TPES) and the photoionization mass spectrometric (PIMS) study of CH3I in the 8-20 eV photon energy range are presented. The interpretation and assignments are supported by ab initio calculations. The TPES shows many new discrete features in the Jahn-Teller split ground X 2E (2A'-2A”) state of CH3I+. A new continuous band starting at about 11.7 eV is detected. These observations are essentially correlated with autoionizing transitions. This interpretation is supported by constant ion state (CIS) spectroscopy. A large enhancement of the transitions to the A 2A and B 2E ionic states is ascribed to large autoionizing contributions. Based on the present calculations, the weak to very weak bands in the 18.0 eV-23.0 eV photon energy range are mainly assigned to 2a1-1 ionization and to double excitations corresponding essentially to the 2e-2 4a11 and 3a1- 1 2e-1 4a11 configurations. The photoionization mass spectrometric study allowed us to investigate in detail the ionization and dissociation of CH3I+ leading to CH2+, CH3+, I+ and CH2I+ from the threshold up to 20 eV photon energy. The experimental data are compared to ab initio calculated dissociation energies. The threshold of appearance of CH3+, I+ and CH2I+ fragments are concentrated in the 12.2-12.7 eV photon energy range. All three exit channels are correlated with the ground state of CH3I+ via nonadiabatic transitions. All three fragment ions have to appear through predissociation of the ionic X 2E state and autoionizing dissociation from the (2E3/2)6p Rydberg state. This interpretation is strongly supported by the photoabsorption spectrum measured recently in the same photon energy range [1]. At higher energies, beside direct or predissociation of the A 2A1 and B 2E states of CH3I+, autoionization is also suggested to contribute to the fragmentation in all decay channels. [less ▲]

The effectiveness of a specific educational programme involving the use of a real-time glucose-sensor system (Guardian RT) to improve glucose control was investigated in patients with poorly controlled type 2 diabetes despite insulin therapy. Ten patients participated in a randomized crossover study comparing two 3-month periods, during which glucose levels were monitored by either self-monitoring of blood glucose (SMBG) alone or by Guardian RT (restricted to 1 week per month) in addition to SMBG. Only four of the enrolled patients completed both periods, while dropouts were mainly due to technical difficulties in using the device. All six patients who completed the first 3-month period showed a reduction in glycated haemoglobin (HbA(1c)) level whatever the mode of glucose monitoring (study effect). A further reduction in HbA(1c) level was observed in two of the three patients using the Guardian RT during the second period. Less frequent symptomatic hypoglycaemic episodes were noted during the 3-month period with the device in the four patients who completed both study periods. These limited, but promising, results of this pilot study appear to justify the initiation of a larger study to assess the use of a real-time glucose sensor in carefully selected patients with type 2 diabetes.

The present study investigated how benevolent (BS) and hostile sexism (HS) shift women’s self-construal and autobiographical memory. Belgian undergraduates (only women, N=45, mean age=21.8) were confronted either by BS, HS or neutral comments in the context of a job interview. After performing a cognitive task, participants reported the intrusive thoughts that came to their mind during the task. Later, autobiographical memory for self-incompetence was assessed. Performance response latencies were slower after BS than HS. Also, BS generated more disturbing mental intrusions related to the idea of being incompetent than HS. Autobiographical memory similarly indicated greater access for incompetence after BS. Although HS was more aggressive in tone, it did not shift women’s self-construal and autobiographical memories toward incompetence. [less ▲]

The continued downscaling of the metal-oxide semiconductor (MOS) transistor for sub-22 nm logic circuits with boosted performance will require the introduction of new channel materials with carrier mobility higher than that of Si, such as Ge for pMOS. The use of III-V compounds for nMOS devices poses however additional challenges related to the hetero-epitaxial growth of a polar semiconductor on a non-polar surface. Furthermore, these high-mobility materials have to be fabricated on large-area Si substrates, in the perspective of application in a standard low-cost very-large-scale integration scheme. In this work, we report on the successful growth of GaAs on 200 mm Si wafers by means of metal-organic vapor deposition using a modified Crius Close-Coupled Showerhead system from AIXTRON AG. We used Si (100) wafers with off-axis orientation (6° miscut towards <111>) in order to avoid the formation of anti-phase domains which lead to Ga-Ga and As-As bonds at their boundaries that have strong detrimental effects on the electrical conduction. In our approach, based on Ge virtual substrates with low threading dislocation (TD) density, the lattice mismatch between Si and GaAs is accommodated and, thus, no additional TD is introduced in the deposited III-V film. Our results show that smooth GaAs layers can be epitaxially grown on large-area Si substrates with high wafer-scale thickness uniformity. The excellent quality of the deposited GaAs was confirmed by photoluminescence and electron microscopy. Our process also demonstrates very high selectivity on patterned wafers with SiO2 mask and enabled the fabrication of capacitor structures using an integration process flow very similar to standard high volume Si manufacturing lines. The capacitance-voltage characteristics were similar to the ones obtained on a bulk GaAs substrate, and showed extremely tight within-wafer and wafer-to-wafer distributions as is standard to Si manufacturing.

Several studies showed that it is more difficult to retrieve semantic information from recognized voices than from recognized faces. However, earlier studies that investigated the recall of biographical information following person recognition used stimuli that were pre-experimentally familiar to the participants, such as famous people’s voices and faces. The present study was designed in order to allow a stricter control of frequency exposure with both types of stimuli (voices and faces) and to ensure the absence of identity cues in the spoken extracts. In the present study, subjects had to associate lexical (i.e., name) and semantic information (i.e., occupation) with faces or voices. Interestingly, when asked later to recall semantic information being cued by the person’s names, participants provided significantly more occupations for the targets that had been previously associated with faces than with voices. Moreover, participants’ performance was not significantly different when names and occupation were associated with voices compared with dog’s faces, whose complexity is similar to that of human faces, but for which we have poorer discrimination abilities. These results and their implications for person recognition models, as well as the potential role of the relative distinctiveness of faces and voices, are discussed. [less ▲]

Purpose: Early assessment of radiotherapy (RT) quality in the ongoing EORTC trial comparing primary temozolomide versus RT in low-grade gliomas. Materials and methods: RT plans provided for dummy cases were evaluated and compared against expert plans. We analysed: (1) tumour and organs-at-risk delineation, (2) geometric and dosimetric characteristics, (3) planning parameters, compliance with dose prescription and Dmax for OAR (4) indices: RTOG conformity index (CI), coverage factor (CF), tissue protection factor (PF); conformity number (CN = PF× CF); dose homogeneity in PTV (U). Results: Forty-one RT plans were evaluated. Only two (5%) centres were requested to repeat CTV-PTV delineations. Three (7%) plans had a significant under-dosage and dose homogeneity in one deviated > 10%. Dose distribution was good with mean values of 1.5, 1, 0.68, and 0.68 (ideal values = 1) for CI, CF, PF, and CN, respectively. CI and CN strongly correlated with PF and they correlated with PTV. Planning with more beams seems to increase PTV Dmin, improving CF. U correlated with PTV Dmax. Conclusion: Preliminary results of the dummy run procedure indicate that most centres conformed to protocol requirements. To quantify plan quality we recommend systematic calculation of U and either CI or CN, both of which measure the amount of irradiated normal brain tissue. © 2010 Elsevier Ireland Ltd.

Within the framework of updating the release and storage capacities of existing reservoirs, the use of piano keys weirs (PKW) can be an interesting alternative either to increase the discharge of a free weir without changing the weir layout or the reservoir level, or increase the reservoir level before discharge while keeping the weir layout and the level of safety. In order to help to the understanding of the behavior of this new type of weirs and to characterize their hydraulic potential, the results of an experimental study with for objectives to study the influence of the relative width of the inlets and outlets on the hydrodynamic characteristics of the structure are presented. A process oriented analytical formulation for the evaluation of the discharge coefficient of the PKW tested on scale models is proposed. It is in satisfactory agreement with the experimental results and leads to an objective evaluation of the optimal ratio of the alveoli widths. [less ▲]

Objective To assess whether the Belgian Hospital Discharge Dataset (B-HDDS) is a valid source for the detection of adverse events in acute hospitals. Design, setting and participants Retrospective review of 1515 patient records in eight acute Belgian hospitals for the year 2005. Main outcome measures Predictive value of the B-HDDS and medical record reviews and degree of correspondence between the B-HDDS and medical record reviews for five indicators: pressure ulcer, postoperative pulmonary embolism or deep vein thrombosis, postoperative sepsis, ventilator-associated pneumonia and postoperative wound infection. Results Postoperative wound infection received the highest positive predictive value (62.3%), whereas postoperative sepsis and ventilator-associated pneumonia were rated as only 44.2% and 29.9% respectively. Excluding present on admission from the screening substantially decreased the positive predictive value of pressure ulcer from 74.5% to 54.3%, as pressure ulcers present on admission were responsible for more B-HDDS-medical record mismatches than any other indicator. Over half (56.8%) of false-positive cases for postoperative sepsis were due to a lack of specificity of the ICD-9-CM code, whereas in 58.6% of false-positive cases for ventilator-associated pneumonia, clinical criteria appeared to be too stringent. Conclusions The B-HDDS has the potential to accurately detect some but not all adverse events. Adding a code 'present on admission' and improving the ICD-9-CM codes might already partially improve the correspondence between the B-HDDS and the medical record review. [less ▲]

The object of study of this work is the invariant characteristics of filtrations in discrete, negative time, pioneered by Vershik. We prove the equivalence between I-cosiness and standardness without using Vershik’s standardness criterion. The equivalence between I-cosiness and productness for homogeneous filtrations is further investigated by showing that the I-cosiness criterion is equivalent to Vershik’s first level criterion separately for each random variable. We also aim to derive the elementary properties of both these criteria, and to give a survey and some complements on the published and unpublished literature. [less ▲]

A sensitive and accurate LC/MS method was developed for the monitoring of glucosamine (GLcN) dog plasmatic concentration. In this scope, relatively low plasmatic concentrations of GLcN were expected, ranging from 50 to 1000ng/mL. Liquid chromatography coupled to simple quadrupole mass spectrometry detection (LC/MS) was selected bringing the selectivity and the sensitivity needed for this application. Additionally, a solid phase extraction (SPE) step was performed to reduce matrix and ion suppression effects. Due to the ionisable character of the compound of interest, a mixed-mode strong cation exchange (Plexa PCX) disposable extraction cartridge (DEC) was selected. The separation was carried out on a Zorbax SB-CN column (5mum, 4.6mm i.d.x250mm), considering hydrophilic interaction liquid chromatography (HILIC). Indeed, the mobile phase was made of methanol and 5mM ammonium hydrogen carbonate buffer at pH 7.5 (95/5, v/v). The detection was led at m/z ratios of 180.0 and 417.0, for GLcN and IS, respectively. Reliability of the results was demonstrated through the validation of the method using an approach based on the accuracy profile allowing managing the risk associated to the use of these methods in routine analysis: it is thus guaranteed that each future result will fall in the +/-30% acceptance limits with a probability of at least 90%. Successful application of the method to a preliminary pharmacokinetic study illustrated the usefulness of the method for pre-clinical studies. [less ▲]

Cutaneous malignant melanoma represents one of the most dramatic skin cancers because its incidence is steadily growing in White populations. Of note, its metastatic risk and mortality dramatically increase when the primary neoplasm reaches about one millimeter thick. It is believed that angiogenesis and lymphangiogenesis associated with cutaneous melanoma potentially influence the neoplastic progression of the primary tumor and its metastases. In some instances, both the intratumoral and peritumoral microvasculature are correlated to booming of the tumoral growth fraction. In addition, the vascular network serves as a migration path for the intravascular and perivascular neoplastic spread. Hence, the quantification of the microvasculature might help establishing a prognostic factor of evolution. Among the available methods, spectral analysis of immunohistochemical sections highlighting vessels helps defining the microvasculature distribution. The benefit of using spectral analysis is discussed and the modalities of application of this analytical method are scrutinized. [less ▲]
