Abstract
An optical simulation of poly(3-hexylthiophene) (P3HT)/Si nanowire array (NWA) hybrid solar cells was investigated to evaluate the optical design requirements of the system by using finite-difference time-domain (FDTD) method. Steady improvement of light absorption was obtained with increased P3HT coating shell thickness from 0 to 80 nm on Si NWA. Further increasing the thickness caused dramatic decrease of the light absorption. Combined with the analysis of ultimate photocurrents, an optimum geometric structure with a coating P3HT thickness of 80 nm was proposed. At this structure, the hybrid solar cells show the most efficient light absorption. The optimization of the geometric structure and further understanding of the optical characteristics may contribute to the development for the practical experiment of the promising hybrid solar cells.
A Higher Sensory Brain Region Is Involved in Reversing Reinforcement-Induced Vocal Changes in a Songbird

Published: May 2014

Many animals exhibit flexible behaviors that they can adjust to increase reward or avoid harm (learning by positive or aversive reinforcement). But what neural mechanisms allow them to restore their original behavior (motor program) after reinforcement is withdrawn? One possibility is that motor restoration relies on brain areas that have a role in memorization but no role in either motor production or in sensory processing relevant for expressing the behavior and its refinement.We investigated the role of a higher auditory brain area in the songbird for modifying and restoring the stereotyped adult song. We exposed zebra finches to aversively reinforcing white noise stimuli contingent on the pitch of one of their stereotyped song syllables. In response, birds significantly changed the pitch of that syllable to avoid the aversive reinforcer. After we withdrew reinforcement, birds recovered their original song within a few days. However, we found that large bilateral lesions in the caudal medial nidopallium (NCM, a high auditory area) impaired recovery of the original pitch even several weeks after withdrawal of the reinforcing stimuli. Because NCM lesions spared both successful noise-avoidance behavior and birds' auditory discrimination ability, our results show that NCM is not needed for directed motor changes or for auditory discriminative processing, but is implied in memorizing or recalling the memory of the recent song target.
Clinical Decision Making on Extensive Molar Restorations

Published: May 2014

SUMMARY
Extensive loss of posterior tooth substance, which traditionally was restored with amalgam or indirect restorations, is more commonly being restored with resin-based composite restorations. Using a questionnaire, we aimed to survey dentists' clinical decision making when restoring extensive defects in posterior molar teeth. The questionnaire, which included questions on background information from the dentists, clinical cases with treatment options, and general questions about restoring extensive posterior defects, was sent to 476 dentists. The response rate was 59%. Multiple logistic regressions were used to investigate the different associations. Most of the respondents preferred a direct composite restoration when one cusp was missing, while indirect restorations were most preferred when replacing three or four cusps. Younger dentists and dentists working in the private sector had a greater tendency to choose an indirect technique compared with older colleagues. Generally, the most important influencing factor in clinical decision making was the amount of remaining tooth substance. Factors that appeared to be less important were dental advertisements, use of fluoride, and dietary habits. Female dentists perceived factors such as oral hygiene, patient requests, and economy to be more important than did their male colleagues.

Published: May 2014

AbstractThe smokybrown cockroach Periplaneta fuliginosa has spread all over the world, and is now one of the most undesired invasive alien pests in Japan. Because cockroaches are generally infected by thelastomatid nematodes, they are being distributed around the world with their parasitic nematodes. Nothing is known about parasitic nematode species in P. fuliginosa differences, or similarity of the parasite’s population structures between the different countries of the host cockroaches. Here we investigated the P. fuliginosa invasive to Japan and found that 100% of individuals were infected with one nematode species. According to the morphology and the sequence of the D2/D3 expansion segment of the 28S ribosomal RNA gene, we identified the parasite as Leidynema appendiculata. This nematode reproduced by haplodiploidy and its developmental timing under various conditions is quite divergent. Their population in the hindgut of P. fuliginosa was controlled with a few adult females and a male. This is the first report of the thelastomatid nematode isolated from the smokybrown cockroach, and is the basis for our future research examining the origin, distribution route and immigration history of the cockroach and the impact of L. appendiculata on native Japanese cockroach species.
Presence of the leech Placobdella costata in the south of the Iberian Peninsula
Authors: Romero David , Duarte Jesús , Narváez-Ledesma Lucía , Farfán Miguel , Real Raimundo 
Published: May 2014

AbstractPlacobdella costata is a leech specific to freshwater turtle Emys orbicularis. Both genera are native to North America and have co-evolved and undergone dispersion through the Palearctic. The leech is present throughout the Mediterranean area, always associated with E. orbicularis. Their only known presence in the Iberian Peninsula is in the north and center of the peninsula. Here we present the first description of the leech in southern Spain (Andalusia) in association with a small fragmented population of fresh-water turtles in which E. orbicularis and Mauremys leprosa coexist. Unusually, the leech was found attached to the carapace of a male M. leprosa.

Published: May 2014

AbstractA parasitological investigation was performed on a total of 5380 Atlantic cod larvae, post-larvae and small juveniles sampled from the North Sea during a period of five years. The copepod Caligus elongatus (Von Nordmann, 1832) and the nematode Hysterothylacium aduncum (Rudolphi, 1802) were found at a relatively high prevalence of infection (4.6% and 5.2%, respectively). The infection by both parasites showed annual and spatial variability. C. elongatus showed a higher prevalence in 1992 compared to the following years, whereas the prevalence of H. aduncum increased from 1992 to 2001.We observed a relation between parasite distribution and parameters such as latitude and water depth. Adult digeneans (Lecithaster gibbosus and Derogenes varicus) and larval cestodes were also found with lower infection rates. Since changes of infection levels coincided with increasing North Sea water temperature in the studied period, it is hypothesized that temperature may affect parasite population levels. However, it is likely that other environmental factors may contribute to the observed variations. Absence of infection intensities higher than one nematode per fish in small larvae and post-larvae suggests that host survival may be affected by a high infection pressure. The relatively high levels of infection in the younger stages of cod, and the annual/spatial variability of these infections should be considered in the understanding of the early life dynamics of the species.
Hysterothylacium gibsoni sp. nov. and H. tetrapteri (Bruce et Cannon, 1989) (Nematoda: Ascaridida) from the Chinese marine fishes
Authors: Xu Zhen , Li Liang , Zhang Lu-Ping 
Published: May 2014

AbstractA new species of ascaridoid nematode, Hysterothylacium gibsoni sp. nov., is described based on specimens collected from the intestine of the slender lizardfish Saurida elongata (Temminck et Schlegel) (Aulopiformes: Synodontidae) in the Yellow Sea, China. The new species differs from its congeners by its small body size (12.8–13.2 mm), the absence of cervical alae, a very short intestinal caecum (representing 8.86–9.52% of oesophageal length) and a long ventricular appendix (intestinal caecum to ventricular appendix ratio 1:15.3–20.0), short spicules (0.38–0.41 mm, representing 2.97–3.11% of body length), the number and arrangement of the caudal papillae (25–28 pairs arranged as follows: 18–22 pairs precloacal, 3 pairs paracloacal, and 3–4 pairs postcloacal). In addition, Hysterothylacium tetrapteri (Bruce et Cannon, 1989) is also redescribed based on the material collected from the striped marlin Kajikia audax (Philippi) (Perciformes: Istiophoridae) in the South China Sea.
Electron spin resonance of FeVO4
Authors: Bojanowski Bohdan , Kaczmarek Sławomir 
Published: May 2014

Abstract
We report on electron spin resonance (ESR) investigations of a FeVO4 single crystal. Temperature and angular dependences of ESR resonance positions were measured and calculated in temperature range of 35–100 K. The spectra show rich angular dependences of the linewidth, the shape and the resonance field. They consist of a single broad line with asymmetric distortion. Due to the low symmetry of the crystal lattice this distortion can be explained by taking into account the influence of non diagonal dynamic susceptibility.

Published: May 2014

Background The objective of this prospective, multicenter, randomized trial was to evaluate and compare 1-year outcomes from the REMODEL study between office balloon dilation and functional endoscopic sinus surgery (FESS). Methods Adults with maxillary chronic rhinosinusitis (CRS), including those with anterior ethmoid disease, who failed medical management and were surgical candidates for FESS, underwent either standalone balloon dilation or FESS in a 1:1 randomization scheme and were followed through a minimum of 1 year. Sinonasal symptom improvement was assessed using the validated 20-item Sino-Nasal Outcome Test (SNOT-20) survey. Standardized effect sizes were computed to further assess clinical significance. Ostial patency rate, rhinosinusitis episode frequency, impact of sinus disease on activity and work productivity using the validated Work Productivity and Activity Impairment survey, complications, and revision rate were also compared between the two groups. Results Ninety-two patients (50 balloon dilation; 42 FESS) were treated and 89 (96 %) completed 1-year follow-up. Both groups showed clinically meaningful and statistically significant (p < 0.0001) improvement in mean overall SNOT-20 scores and in all four SNOT-20 subscales. The 1-year mean change in SNOT-20 after balloon dilation (-1.64) was noninferior to FESS (-1.65; p < 0.001). The standardized effect size was large, showing clinically significant improvement for both interventions. Ostial patency was 96.7 and 98.7% after balloon dilation and FESS, respectively, and each group reported significant reductions (p < 0.0001) in rhinosinusitis episodes (mean decrease, 4.2 for balloon dilation and 3.5 for FESS). Overall work productivity and daily activity impairment due to chronic sinusitis were significantly improved (p < 0.001) in both groups. There were no complications and revision surgery rate was 2% in each arm through 1 year. Conclusion With 1-year follow-up, standalone balloon dilation is as effect as FESS in the treatment of CRS in patients with maxillary sinus disease with or without anterior ethmoid disease who failed medical therapy and met the criteria for medically necessary FESS.

SummaryObjective: The purpose of this study is to investigate the impact of cognitive group therapy and happiness training objectively in the local cerebral blood flow of patients with major depression (MD). Patients, material, methods: The present research is semi-experimental to pre- and post-test with a control group. Three groups were formed, and this number was incorporated in each group: 12 patients were chosen randomly; the first group of depressed patients benefited from the combination of pharmacotherapy and sessions of cognitive group therapy; the second group used a combination of pharmaco- therapy and sessions of happiness training; and a third group used only pharmacother- apy. We compared cognitive-behavioural therapy and happiness training efficacy with only pharmacotherapy in MD patients. We performed brain perfusion SPECT in each group, before and after each trial. Results: The study was conducted on 36 patients with MD (32 women and 4 men; mean age: 41.22 ± 9.08; range: 27-65 years). There were significant differences regarding the two trial effects into two experimental groups (p < 0/001) before and after trials, while such differences were not significant in the control group (p > 0.05). In addition, there was significant difference among the regional cerebral blood flow in the frontal and prefrontal regions into two experimental groups before and after trials (p < 0/001), while such differences were not significant in the control group (p > 0.05). Conclusion: This study demonstrated decreased cerebral perfusion in the frontal regions in MD patients, which increased following cognitive group therapy and happiness training. Because of its availability, low costs, easy performance, and the objective semi-quantitative information supplied, brain perfusion SPECT

A travers une étude comparée de trois objets (la ville, le SI et l’entreprise), cet article conceptuel propose d’identifier et de caractériser un nouveau modèle de représentation et de pilotage de la complexité dans les organisations : le modèle multipolaire. Après une synthèse des principes du modèle fonctionnaliste, nous soulignons la rupture que marque le modèle multipolaire, ainsi que les nouvelles questions de management et de transformation des organisations qui se posent. L’outillage SI, encore largement en phase d’élaboration, sera un élément clé pour la gestion des entreprises multipolaires.

Trois termes : égalité, non-discrimination et diversité traitent du rapport à la différence et sont étudiés. Les principaux résultats d’une enquête conduite auprès de 15 responsables de la diversité au sein de groupes internationaux sont restitués. Si la diversité est perçue comme souple et liée à la performance, la non-discrimination semble un préalable nécessaire mais largement insuffisant. La notion d’égalité laisse au final perplexe les managers de la diversité.
Impact of Homecare Electronic Health Record on Timeliness of Clinical Documentation, Reimbursement, and Patient Outcomes
Authors: Bowles K. H. , Adelsberger M. C. , Chittams J. L. , Liao C. , Sockolow P. S. 
Published: May 2014

SummaryBackground: Homecare is an important and effective way of managing chronic illnesses using skilled nursing care in the home. Unlike hospitals and ambulatory settings, clinicians visit patients at home at different times, independent of each other. Twenty-nine percent of 10,000 homecare agencies in the United States have adopted point-of-care EHRs. Yet, relatively little is known about the growing use of homecare EHRs.Objective: Researchers compared workflow, financial billing, and patient outcomes before and after implementation to evaluate the impact of a homecare point-of-care EHR.Methods: The design was a pre/post observational study embedded in a mixed methods study. The setting was a Philadelphia-based homecare agency with 137 clinicians. Data sources included: (1) clinician EHR documentation completion; (2) EHR usage data; (3) Medicare billing data; (4) an EHR Nurse Satisfaction survey; (5) clinician observations; (6) clinician interviews; and (7) patient outcomes.Results: Clinicians were satisfied with documentation timeliness and team communication. Following EHR implementation, 90% of notes were completed within the 1-day compliance interval (n = 56,702) compared with 30% of notes completed within the 7-day compliance interval in the pre-implementation period (n = 14,563; OR 19, p < .001). Productivity in the number of clinical notes documented post-implementation increased almost 10-fold compared to pre-implementation. Days to Medicare claims fell from 100 days pre-implementation to 30 days post-implementation, while the census rose. EHR implementation impact on patient outcomes was limited to some behavioral outcomes.Discussion: Findings from this homecare EHR study indicated clinician EHR use enabled a sustained increase in productivity of note completion, as well as timeliness of documentation and billing for reimbursement with limited impact on improving patient outcomes. As EHR adoption increases to better meet the needs of the growing population of older people with chronic health conditions, these results can inform homecare EHR development and implementation.Citation: Sockolow PS, Bowles KH, Adelsberger MC, Chittams JL, Liao C.

SummaryObjective: To assses the relationship between methods of documenting visit notes and note quality for primary care providers (PCPs) and specialists, and to determine the factors that contribute to higher quality notes for two chronic diseases.Methods: Retrospective chart review of visit notes at two academic medical centers. Two physicians rated the subjective quality of content areas of the note (vital signs, medications, lifestyle, labs, symptoms, assessment & plan), overall quality, and completed the 9 item Physician Documentation Quality Instrument (PDQI-9). We evaluated quality ratings in relation to the primary method of documentation (templates, free-form or dictation) for both PCPs and specialists. A one factor analysis of variance test was used to examine differences in mean quality scores among the methods.Results: A total of 112 physicians, 71 primary care physicians (PCP) and 41 specialists, wrote 240 notes. For specialists, templated notes had the highest overall quality scores (p≤0.001) while for PCPs, there was no statistically significant difference in overall quality score. For PCPs, free form received higher quality ratings on vital signs (p = 0.01), labs (p = 0.002), and lifestyle (p = 0.002) than other methods; templated notes had a higher rating on medications (p≤0.001). For specialists, templated notes received higher ratings on vital signs, labs, lifestyle and medications (p = 0.001).Discussion: There was no significant difference in subjective quality of visit notes written using free-form documentation, dictation or templates for PCPs. The subjective quality rating of templated notes was higher than that of dictated notes for specialists.Conclusion: As there is wide variation in physician documentation methods, and no significant difference in note quality between methods, recommending one approach for all physicians may not deliver optimal results.Citation: Neri PM, Volk LA, Samaha S, Pollard SE, Williams DH, Fiskio JM, Burdick E, Edwards ST, Ramelson H, Schiff GD, Bates DW.

Robotic Pyeloplasty: The Results after the First 30 Patients
Authors: Gallo Fabrizio , Schenone Maurizio , Cortese Pierluigi , Giberti Claudio 
Published: May 2014

Introduction The aim of this paper is to report the outcomes of 30 (first) robot-assisted pyeloplasties (RPs) performed at our institute for the treatment of ureteropelvic junction obstruction (UPJO). Methods In the period between March 2005 and September 2012, 30 RPs due to UPJO have been performed at our institute using a three arms Da Vinci Robot, standard version. All the procedures were performed transperitoneally with Anderson-Hynes technique. 29/30 (97%) patients were affected by primary UPJO and 1/30 (3%) reported a recurrent disease. The access foresaw the positioning of three robotic trocars (one 12 mm trocar for the camera and two 8-mm trocars for the robotic arms) and one assistant 12 mm trocar. The anastomosis was confectioned on a double-J ureteral tutor with 4/0 monocryl running sutures. Outcome success was defined as resolution of preoperative symptoms and ureteropelvic junction obstruction, confirmed by the improvement of the diuretic renogram. Mean follow-up was 48.3 months (range 5–96). Results All procedures have been completed robotically and no conversion was needed. Mean operative times, blood losses and hospital stay were respectively 189 minutes (range 105–420), 60 mL (range 25–100) and 4.2 days (range 2–14). 29/30 patients were cured, with a success rate of 97%. As regards mild complications, 3/30 patients (10%) reported a moderate abdominal pain a few hours after surgery, which was successfully treated with common analgesic drugs. As for major complications, one patient (3%) developed ileus, probably due to a mild urine extravasation through the ureteropelvic suture, which spontaneously disappeared three days after surgery. Conclusions RP seems to be a “new gold standard” in the treatment of UPJO. The three-dimensional versatility and the outstanding accuracy of robot-assisted intracorporeal suturing produced excellent results after the first procedures without requiring a previous 'sound' laparoscopic experience.
