Non-Coherent Cooperative Communications Dispensing with Channel Estimation Relying on Erasure Insertion Aided Reed-Solomon Coded SFH M-ary FSK Subjected to Partial-Band Interference and Rayleigh Fading
No full textThe rationale of our design is that although much of the literature of cooperative systems assumes perfect coherent detection, the assumption of having any channel estimates at the relays imposes an unreasonable burden on the relay station. Hence, non-coherently detected Reed-Solomon (ReS) coded Slow Frequency Hopping (SFH) assisted M -ary Frequency Shift Keying (FSK) is proposed for cooperative wireless networks, subjected to both partial-band interference and Rayleigh fading. Erasure insertion (EI) assisted ReS decoding based on the joint maximum output-ratio threshold test (MO-RTT) is investigated in order to evaluate the attainable system performance. Compared to the conventional error-correction-only decoder, the EI scheme may achieve an Eb/N0 gain of approximately 3dB at the Codeword Error Probability, Pw , of 10-4 , when employing the ReS (31, 20) code combined with 32-FSK modulation. Additionally, we evaluated the system’s performance, when either equal gain combining (EGC) or selection combining (SC) techniques are employed at the destination’s receiver. The results demonstrated that in the presence of one and two assisting relays, the EGC scheme achieves gains of 1.5 dB and 1.0 dB at the Pw of 10-6 , respectively, compared to the SC arrangement. Furthermore, we demonstrated that for the same coding rate and packet size, the ReS (31, 20) code using EI decoding is capable of outperforming convolutional coding, when 32-FSK modulation is considered, whilst LDPC coding had an edge over the above two schemes

Strain mutants without antagonistic properties appeared several times spontaneously
Development of the Liang Handover Assessment Tool for Simulation (L-HATS)
No full textThe general metadata -- e.g., title, author, abstract, subject headings, etc. -- is publicly available, but access to the submitted files is restricted to UT Southwestern campus access and/or authorized UT Southwestern users.INTRODUCTION: Clinical handovers are critical to patient safety and outcomes. Handover simulation prepares healthcare students for handoffs in the clinical setting upon graduation. UT Southwestern has developed a longitudinal handover educational curriculum in which student handovers will be assessed. Although valid and reliable tools exist for assessing clinical handovers, assessment tools adapted for the undergraduate simulation environment currently do not exist. Our objective was to develop a reliable and valid assessment tool that could be used by scholarly healthcare students to assess undergraduate simulated handovers throughout the longitudinal handover education curriculum.
METHODS: A literature review was conducted to identify critical elements of high-quality, effective handovers. Following the tool's creation, we underwent several PDSA cycles to optimize the tool for medical student evaluation and ease of grading. Grader inclusion criteria were students who had completed the transition to clerkship (T2C) handover activity. A training curriculum was developed to train graders on proper use of the tool and to promote reliable grading with the tool. 62 pre-clinical student handovers were conducted in the simulation setting and recorded. The handovers were stratified into three levels (low, intermediate, and high quality), and 10 handovers were selected from each of the three levels for grading (30 handovers total). Each handover was scored by four clerkship medical students "graders". Two-way random effects intra-class correlation coefficients (ICC) were used to establish inter-rater reliability and inter-rater agreement among graders using the tool. Three external handover experts were used to establish the tool's validity using face validity.
RESULTS: The product of this project is Liang Handover Assessment Tool for Simulation (L-HATS) which evaluated three domains: handover content, handover process, and language with a maximum score of 28. Two-way random effects ICC for agreement was 0.804, 95% CI [0.601, 0.906]. Two-way random effects ICC for reliability was 0.866, 95% CI [0.765, 0.930]. Three external handover experts have sufficiently validated the tool.
CONCLUSIONS: The L-HATS had good to excellent inter-rater reliability and agreement. The L-HATS is the first reliable and valid handover assessment tool used for undergraduate simulation education. By using a two-way random effects model, the results suggest that the tool can be used in settings outside of the T2C handover simulation activity. Having good to excellent absolute agreement suggests that the tool is suitable for assigning grades. Future studies include comparing faculty vs student grading of handovers as well as evaluating the tool in the clinical setting

Polystichum jinpingense Z. L. Liang, Liang Zhang & Li Bing Zhang 2022, sp. nov.
No full textPolystichum jinpingense Z.L.Liang, Liang Zhang & Li Bing Zhang, sp. nov. (Figures 1, 2). Type:— CHINA. Yunnan Province: Jinping County, Tongchangxiang Town, Maobeiwan Village, elev. 1800–2000 m, 22°45’53.45”N, 103°01’22.20”E, on limestone rocks in disturbed secondary forest, 9 September 2019, Z.- L . Liang, Y.- M. Shui, W.- H. Chen & Z.- Y. Yu LZL605 (holotype KUN1497023!, isotype CDBI!). Diagnosis:— Polystichum jinpingense is most similar to P. subacutidens Ching ex L.L. Xiang (1994: 261) by having similar plant size and numerous pairs of pinnae, but the former has more or less straight pinnae forming a right angle with rachis (vs. mostly reflexed in the latter), pinna margins undulate (vs. serrate in the latter), pinna apex round (vs. acute in the latter), and sori that are closer to pinna margins (vs. sori that are in the middle between pinna margins and midribs in the latter). Plants perennial, evergreen, (38–) 45–48.5 cm tall. Rhizomes erect, ca. 2 cm long, ca. 1.5 cm in diam., with remnant bases of old petioles; roots dull brown when dried, up to 10 cm long, ca. 0.5 mm in diam. Leaves in tufts; petioles 9.5– 16.5 cm long, ca. 1.5 mm in diam., stramineous basal portions covered with scales; proximal petiole scales ovate to ovate-lanceolate, 1–2 × 0.5–1 mm, papery, dull brown or brown, margins subentire, apex acuminate, cells rectangular in the middle, twisted in the margins; distal petiole scales ovate-lanceolate, 0.8–1.2 × 0.4–0.8 mm, membranous, margins subentire, apex long-acuminate or caudate. Laminae lanceolate, 1-pinnate, (25.5–) 28–32 cm long, 1.8–2.8 cm wide, apex acuminate; rachises ca. 0.9 mm in diam., stramineous, adaxially sulcate; rachis scales ovate or ovatelanceolate, light brown, up to 1 mm long including tip, 0.5 mm wide at base, margins fimbriate, apex long-caudate; or scales bristle-like, ca 1 mm long, margins entire and fimbriate at base. Pinnae in 58–62 pairs, alternate, separate from each other, 2–3 mm distance, oblong, base cuneiform, apex cuspidate, papery, maximal pinnae 0.9–1.3 × 0.35–0.5 cm, basal pinnae narrowing down and basal 1 pair reflexed, largest pinnae located above middle part of lamina, proximal margins not overlapping rachis, acroscopic and basiscopic margins cartilaginous, undulate or with irregular teeth, forming a (80–)90–100° angle with rachis, apex acuminate; basal pinnae margins undulate or entire, apex obtuse; pinna petioles 0.5–1 mm long; adaxially glabrous; abaxially with microscales; microscales broad, ovate or ovatelanceolate, or lanceolate, whitish brown, 0.5–1(–1.5) mm long, 0.15–0.45 mm wide at base, margins fimbriate; costa sunken abaxially and protruding adaxially, veins obscure and invisible on adaxial side, bulging and thickened on abaxial side, lateral veins free, forked. All pinnae bear sori on fertile fronds excluding 5–8 pairs at base; sori terminal on lateral veins of fertile pinnae, 0.8–1.2 mm in diam., closer to pinna margins than to midrib (centers of sori 0.5–1 mm from pinna margins, 1.5–2 mm from midrib), 1–3 on acroscopic side and 6–8 on distal basiscopic side, centers 1–1.5 mm apart from one another. Indusia not seen. Geographical distribution:— Polystichum jinpingense is only found in Jinping County, Yunnan Province, and may represent an endemic species to southern Yunnan. Ecology:— Polystichum jinpingense was observed to grow on limestone rocks in the planted forest at elevations between 1800 and 2000 m. IUCN Red List category:—Only one population of Polystichum jinpingense was found in Jinping. Based on current information and following the IUCN (The International Union for Conservation of Nature and Natural Resources) guidelines (IUCN, 2017), this new species should be classified as Critically Endangered (CR). Etymology:—The species epithet jinpingense is based on the Chinese pinyin, jinping, the county name in southeastern Yunnan, and the Latin suffix -ense, of origin, referring to the type locality and the current known distribution of the species in Jinping County, Yunnan. Vernacular name:— İ平Ąĸ (jin ping er jue). Taxonomic notes:— Polystichum jinpingense was initially identified as P. subacutidens for its striking similarity of numerous pairs of pinnae to those of the latter. Polystichum subacutidens was the only species known in the genus with so many pairs of pinnae (Xiang 1994, Zhang & Barrington 2013). Careful comparison showed that they two are quite different morphologically. In addition, P. jinpingense grows at higher elevations (1800–2000 m), whereas P. subacutidens occurs between 700–1500 m. Interestingly, both P. jinpingense and P. subacutidens were first discovered and have types collected from the same county. Now the known distribution of P. subacutidens has been expanded to southern Guizhou (Changshun, Ziyun), northwestern Guangxi (Leye, Nandan), in addition to southeastern Yunnan (Zhang & Barrington 2013). It is even found in northern Vietnam (Lu et al. 2014). It remains to discover where else P. jinpingense occurs.Published as part of Liang, Zhen-Long, Yu, Zhi-Yong, Chen, Wen-Hong, Tunçkol, Bilge, Zhang, Liang & Zhang, Li- Bing, 2022, Polystichum jinpingense (subg.

But when they published their paper (Liang <i>et al.</i>, 1984), however, they changed its name to <i>C. disparidentata</i>. In a later paper reviewing the <i>Caridina</i> species from Yunnan, however, Liang and Yan (1985) erroneously used their original but unpublished name, <i>C. heterodentata</i>, for the species, apparently forgetting that they had used the name <i>C. disparidentata</i> in their 1984 publication! <i>Caridina heterodentata</i> Liang and Yan, 1985, must thus be regarded as an unjusti®ed emendation of <i>C. disparidentata</i> Liang, Yan and Wang, 1984.
