A remarkable new leaf-cutter bee from Thailand (Hymenoptera: Megachilidae)
This is the publisher's version, copyright by Akademie Verlag.A remarkable new species of leaf-cutter bee, Megachile trichorhytisma ENGEL sp. n., is described and figured from two males collected in northern Thailand. The species is placed in a new subgenus, Aethomegachile ENGEL & BAKER subgen. n., and is differentiated from previously known lineages of Megachile
An integrated care pathway for menorrhagia across the primary–secondary interface : patients' experience, clinical outcomes, and service utilisation
Background: ‘‘Referral’’ characterises a significant area of interaction between primary and secondary care.
Despite advantages, it can be inflexible, and may lead to duplication.
Objective: To examine the outcomes of an integrated model that lends weight to general practitioner (GP)-led
evidence based care.
Design: A prospective, non-random comparison of two services: women attending the new (Bridges) pathway
compared with those attending a consultant-led one-stop menstrual clinic (OSMC). Patients’ views were
examined using patient career diaries, health and clinical outcomes, and resource utilisation. Follow-up was
for 8 months.
Setting: A large teaching hospital and general practices within one primary care trust (PCT).
Results: Between March 2002 and June 2004, 99 women in the Bridges pathway were compared with 94
women referred to the OSMC by GPs from non-participating PCTs. The patient career diary demonstrated a
significant improvement in the Bridges group for patient information, fitting in at the point of arrangements
made for the patient to attend hospital (ease of access) (p,0.001), choice of doctor (p = 0.020), waiting time
for an appointment (p,0.001), and less ‘‘limbo’’ (patient experience of non-coordination between primary
and secondary care) (p,0.001). At 8 months there were no significant differences between the two groups in
surgical and medical treatment rates or in the use of GP clinic appointments. Significantly fewer (traditional)
hospital outpatient appointments were made in the Bridges group than in the OSMC group (p,0.001).
Conclusion: A general practice-led model of integrated care can significantly reduce outpatient attendance
while improving patient experience, and maintaining the quality of care
Discrimination of prostate cancer cells and non-malignant cells using secondary ion mass spectrometry
This communication utilises Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) combined with multivariate analysis to obtain spectra from the surfaces of three closely related cell lines allowing their discrimination based upon mass spectral ions
Limitations for change detection in multiple Gabor targets
We investigate the limitations on the ability to detect when a target has changed, using Gabor targets as simple quantifiable stimuli. Using a partial report technique to equalise response variables, we show that the log of the Weber fraction for detecting a spatial frequency change is proportional to the log of the number of targets, with a set-size effect that is greater than that reported for visual search. This is not a simple perceptual limitation, because pre-cueing a single target out of four restores performance to the level found when only one target is present. It is argued that the primary limitation on performance is the division of attention across multiple targets, rather than decay within visual memory. However in a simplified change detection experiment without cueing, where only one target of the set changed, not only was the set size effect still larger, but it was greater at 2000 msec ISI than at 250 msec ISI, indicating a possible memory component. The steepness of the set size effects obtained suggests that even moderate complexity of a stimulus in terms of number of component objects can overload attentional processes, suggesting a possible low-level mechanism for change blindness
Modeling and Simulating Computer Networks Using Formalized Data Flow Diagrams
Formalized Data Flow Diagrams (FDFD\u27s) provide simple and natural abstractions for specifying network behavior. We have augmented FDFD\u27s by providing (i) a notion of asynchronous timing of events, (ii) a convenient mechanism for describing node classes , and (iii) features for specifying network architecture. These extensions will facilitate the modeling of a large computer network (using the langauge NET-SPECS) and the direct generation of a simulator of that network
Late Time Barium Cloud Striations and Their Possible Relationship to Equatorial Spread F
An active experiment has been conducted in space that allows a test for the theory of nonlinear development of striations in large barium clouds. The results are in excellent agreement with a computer simulation of the ExB instability reported by Scannapiecoe t al. (1976). The power law irregularity spectrum predicted by the theory and verified by the experiment is shown here to be due to wave steepeninga nd not_top lasmat urbulence.T he barium cloud resultsa re remarkably similar to bottomside equatorial spread F. A possible role of the E x B instability in bottomside equatorial spread F is discussed as a supplement to the Rayleigh-Taylor instability during the postsunset rise of the F layer and during anomalousp lasma uplifts which occur during geomagneticallya ctive period
