Tikuna bilineata Needham & Murphy, comb. n.
No full textTikuna bilineata (Needham & Murphy) comb. n. Choroterpes bilineata Needham & Murphy 1924: 48; Traver 1947: 156. The genus Tikuna was established by Savage et al. (2005) and Choroterpes atramentum Traver, 1947, was designated as the type species. Following this publication, two species from South and Central America remain incorrectly placed in Choroterpes. The first, Choroterpes bilineata Needham & Murphy, 1924, originally described from female imagos and male subimagos from La Chorrera, Putumayo Dist., Peru (now a part of Colombia), also belongs to the genus Tikuna, requiring the new combination Tikuna bilineata. The holotype and paratypes (Cornell University) were studied by one of us (H.M. Savage); additional specimens deposited at the U. S. National Museum of Natural History, Florida A&M University, and the Zoologische Sammlung des Bayerischen Staates were recorded from Brazil, Ecuador, Surinam, and Venezuela. New records for T. bilineata follow: BRAZIL: 1 female imago, Pará State, Rio Cururu, about 100 km above Mission Cururu, at light, 25 –I– 1962, E.J. Fittkau. ECUADOR: Pastaza Prov., coll. J.

Improving management of ARDS: uniting acute management and long-term recovery
No full textAcute Respiratory Distress Syndrome (ARDS) is an important global health issue with high in-hospital mortality. Importantly, the impact of ARDS extends beyond the acute phase, with increased mortality and disability for months to years after hospitalization. These findings underscore the importance of extended follow-up to assess and address the Post-Intensive Care Syndrome (PICS), characterized by persistent impairments in physical, cognitive, and/or mental health status that impair quality of life over the long-term. Persistent muscle weakness is a common physical problem for ARDS survivors, affecting mobility and activities of daily living. Critical illness and related interventions, including prolonged bed rest and overuse of sedatives and neuromuscular blocking agents during mechanical ventilation, are important risk factors for ICU-acquired weakness. Deep sedation also increases the risk of delirium in the ICU, and long-term cognitive impairment. Corticosteroids also may be used during management of ARDS, particularly in the setting of COVID-19. Corticosteroids can be associated with myopathy and muscle weakness, as well as prolonged delirium that increases the risk of long-term cognitive impairment. The optimal duration and dosage of corticosteroids remain uncertain, and there's limited long-term data on their effects on muscle weakness and cognition in ARDS survivors. In addition to physical and cognitive issues, mental health challenges, such as depression, anxiety, and post-traumatic stress disorder, are common in ARDS survivors. Strategies to address these complications emphasize the need for consistent implementation of the evidence-based ABCDEF bundle, which includes daily management of analgesia in concert with early cessation of sedatives, avoidance of benzodiazepines, daily delirium monitoring and management, early mobilization, and incorporation of family at the bedside. In conclusion, ARDS is a complex global health challenge with consequences extending beyond the acute phase. Understanding the links between critical care management and long-term consequences is vital for developing effective therapeutic strategies and improving the quality of life for ARDS survivors

Uncovering the truth behind Vygotsky's cognitive apprenticeship: engaging reflective practitioners in the 'master-apprentice' relationship
No full textIn recent years theories of situated cognition sharing the idea that learning and doing are inseparable as part of a process of enculturation, largely based upon the work of Vygotsky in developing a model of ‘cognitive apprenticeship’, have received much attention in education (Vygotsky, 1978) as an insightful model underpinning forms of learning and teaching. The master-apprentice relationship using techniques of apprenticeship such as modelling, scaffolding and reflection has since been used as a base for considerable research helping researchers and practitioners to understand teacher-student action across a range of different teaching situations (Collins et al., 1989; Hennessy, 1993; Jarvela, 1995; Rojewski et al., 1994). The focus of much of this research has explored the efficacy of the model when set against the question of how to improve forms of learning and teaching in particular settings

Precision measurement of D meson mass differences
No full textUsing three- and four-body decays of D mesons produced in semileptonic b-hadron decays, precision measurements of D meson mass differences are made together with a measurement of the D 0 mass. The measurements are based on a dataset corresponding to an integrated luminosity of 1.0 fb−1 collected in pp collisions at 7 TeV. Using the decay D 0 → K + K − K − π +, the D 0 mass is measured to be M(D0)=1864.75±0.15(stat)±0.11(syst)MeV/c2.
The mass differences
M(D+)−M(D0)=4.76±0.12(stat)±0.07(syst)MeV/c2,M(Ds)−M(D+)=98.68±0.03(stat)±0.04(syst)MeV/c2
are measured using the D 0 → K + K − π + π − and D+(s)→K+K−π+ mode
Study of DsJ decays to D+KS0 and D0K+ final states in pp collisions
No full textA study of D+K0S and D0K+ final states is performed in a sample of 1.0 fb−1 of pp collision data collected at a centre-of-mass energy of s√=7 TeV with the LHCb detector. We confirm the existence of the D∗s1(2700)+ and D∗sJ(2860)+ excited states and measure their masses and widths to be
m(D∗s1(2700)+) = 2709.2±1.9(stat)±4.5(syst) MeV/c2, Γ(D∗s1(2700)+) = 115.8±7.3(stat)±12.1(syst) MeV/c2, m(D∗sJ(2860)+) = 2866.1±1.0(stat)±6.3(syst) MeV/c2, Γ(D∗sJ(2860)+) = 69.9±3.2(stat)±6.6(syst) MeV/c2
Verifying security protocols by knowledge analysis
No full textThis paper describes a new interactive method to analyse knowledge of participants involved in security protocols and further to verify the correctness of the protocols. The method can detect attacks and flaws involving interleaving sessions besides normal attacks. The implementation of the method in a generic theorem proving environment, namely Isabelle, makes the verification of protocols mechanical and efficient; it can verify a medium-sized security protocol in less than ten seconds. As an example, the paper finds the flaw in the Needham-Schroeder public key authentication protocol and proves the secure properties and guarantees of the protocol with Lowe's fix to show the effectiveness of this method
Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate
Megalestes micans Needham 1930

Megalestes chengi Chao, 1947: 15–25, figs. 2, 4, 6, 8, 10–11, 14, 16–17, 21; Chao 1965: 190–191; Asahina 1985b: 9–12. Syn. nov. Megalestes discus Wilson, 2004: 424–427, figs. 4–8, [Mangshan, Hunan, China]; Wilson & Xu 2007: 102–103, “Nanling, Guangdong,” key to species. Syn. nov. Megalestes raychoudhurii Lahiri, 1987: 54–56, figs. 131–132, 298–299, 519 [Meghalaya, India]. Syn. nov. Megalestes irma [nec. Fraser, 1926]: Gyeltshen et al., 2017: 588–594, fig. 4e–f [Bhutan]. This is the most widespread species of Megalestes, occurring throughout South China (Fujian, Guangdong, Guangxi, Guizhou, Henan, Hunan, Jiangxi, Sichuan, Yunnan, and Zhejiang) extending to Vietnam, Bhutan, and India. It is also the only species distributed on both sides of the Himalayas. The diagnostic character for this mid-sized species is the base of the basal tooth on the paraproct bulged, covered in dense setae (Fig. 6 i-j). This species is closely related to M. riccii, and this was confirmed by molecular analysis (Fig. 7). In the description of M. chengi, Chao (1947) only compared his material with M. heros, a totally different species. Later, Chao (1965) stated that the differences between M. chengi and M. micans included the middle portion of the middle lobe of the pronotum green, not yellow (feature 2), and the base of the basal tooth of the paraproct slightly, but not greatly, bulged (feature 15). However, all these characters occur in intraspecies variation (Discussion section). Although both Chao (1965) and Asahina (1985b) have emphasized that M. chengi was very similar to M. micans, neither author confirmed that they are really the same species. We examined eight of the type specimens of M. chengi deposited in IZAS and IEAS including the holotype and found no evident morphological differences with M. micans. The molecular analyses also suggested that these two are the same species (Fig. 7). Therefore, based on both morphological and molecular evidence (Fig. 8), we confirm that M. chengi is a junior synonym of M. micans. As we have previously discussed, diagnostic characters of M. discus cannot separate it from M. micans. Wilson & Xu (2007) mentioned that M. discus have “inferior appendages without a basal pair of stout spines or robust teeth,” which is incorrect, and “occipital margin with/without transverse yellow spot” (feature 1) supports our opinion that this character is not stable. We examined the diagnostic character photos of the paratype of discus (1 m #, Mangshan (near Babaoshan), Shikengkong, S Hunan, China, 26-VI-2000, K.D.P. Wilson leg.), which were kindly sent by K. D. P. Wilson, and found that all the characters are consistent with M. micans. No further information on M. raychoudhurii has been published after its original description. According to the features of caudal appendages and genital ligula in the original description and figures, there is no difference between M. raychoudhurii and M. micans. We believe that both discus and M. raychoudhurii are junior synonyms of M. micans.Published as part of Yu, Xin & Xue, Junli, 2020, A review of the damselfly genus Megalestes Selys, 1862 (Insecta: Odonata Zygoptera: Synlestidae) using integrative taxonomic methods, pp. 245-270 in Zootaxa 4851 (2) on page 262, DOI: 10.11646/zootaxa.4851.2.2, http://zenodo.org/record/440747
