STAHL: A Novel Scan-Test-Aware Hardened Latch Design

As modern technology nodes become more susceptible to soft errors, many radiation hardened latch designs have been proposed. However, redundant circuitry used to tolerate soft errors in such hardened latches also reduces the test coverage of cell-internal manufacturing defects. To avoid potential test escapes that lead to soft error vulnerability and reliability issues, this paper proposes a novel Scan-Test-Aware Hardened Latch (STAHL). Simulation results show that STAHL has superior defect coverage compared to previous hardened latches while maintaining full radiation hardening in function mode.24th IEEE European Test Symposium (ETS\u2719), May 27-31, 2019, Baden-Baden, German

Unreliable quantitation of species abundance based on high-throughput sequencing data of zooplankton communities

High-throughput sequencing (HTS) is rapidly becoming a popular and robust tool to characterize biodiversity of complex communities, especially for those dominated by microscopic species such as zooplankton. The popular use of HTS-based methods has prompted a possible method of inferring relative species abundance from sequencing data. However, these methods remain largely untested in many communities as to whether sequence data can reliably quantify relative species abundance. Here we tested the relationship between species abundance and sequence abundance in zooplankton using 2 methods: (1) spiking known amounts of indicator species into existing zooplankton communities, and (2) comparing results obtained from parallel replicates for the same natural zooplankton communities. Although we detected a general trend that low-abundance species usually corresponded to low-abundance sequence reads, further statistical analyses revealed that sequencing data could not reliably quantify relative species abundance, even for the same indicator species spiked into different zooplankton communities. The distribution of sequence reads statistically varied even between parallel replicates of the same natural zooplankton communities. Our study reveals that sequence abundance may generally qualitatively reflect species abundance as the general trend between these 2 variables exists; however, extra caution is required when using HTS-based approaches to make quantitative inferences regarding zooplankton communities

Actively implementing an evidence-based feeding guideline for critically ill patients (NEED): a multicenter, cluster-randomized, controlled trial

Background: Previous cluster-randomized controlled trials evaluating the impact of implementing evidence-based guidelines for nutrition therapy in critical illness do not consistently demonstrate patient benefits. A large-scale, sufficiently powered study is therefore warranted to ascertain the effects of guideline implementation on patient-centered outcomes. Methods: We conducted a multicenter, cluster-randomized, parallel-controlled trial in intensive care units (ICUs) across China. We developed an evidence-based feeding guideline. ICUs randomly allocated to the guideline group formed a local "intervention team", which actively implemented the guideline using standardized educational materials, a graphical feeding protocol, and live online education outreach meetings conducted by members of the study management committee. ICUs assigned to the control group remained unaware of the guideline content. All ICUs enrolled patients who were expected to stay in the ICU longer than seven days. The primary outcome was all-cause mortality within 28 days of enrollment. Results: Forty-eight ICUs were randomized to the guideline group and 49 to the control group. From March 2018 to July 2019, the guideline ICUs enrolled 1399 patients, and the control ICUs enrolled 1373 patients. Implementation of the guideline resulted in significantly earlier EN initiation (1.20 vs. 1.55 mean days to initiation of EN; difference − 0.40 [95% CI − 0.71 to − 0.09]; P = 0.01) and delayed PN initiation (1.29 vs. 0.80 mean days to start of PN; difference 1.06 [95% CI 0.44 to 1.67]; P = 0.001). There was no significant difference in 28-day mortality (14.2% vs. 15.2%; difference − 1.6% [95% CI − 4.3% to 1.2%]; P = 0.42) between groups. Conclusions: In this large-scale, multicenter trial, active implementation of an evidence-based feeding guideline reduced the time to commencement of EN and overall PN use but did not translate to a reduction in mortality from critical illness.

Legends, Inspirations and Space: Landscape Sacralization of the Sacred Site Mount Putuo

Mount Putuo in Zhejiang Province, China, is the most important holy land of Guanyin in East Asia. Landscape sacralization is a key modality by which sacred meaning is constructed. This paper takes several examples—the Tidal Sound Cave (“chaoyin dong” 潮音洞), the Well of the Immortal Mei (“Meixian jing” 梅仙井), the Well of Ge Hong (“Ge Hong jing” 葛洪井), the Well of the Immortal (“xianren jing” 仙人井), and Duangu Pier (“Duan Gu daotou” 短姑道頭)—to analyze the three types of processes of sacralization. The Tidal Sound Cave is a re-construction of the founding myths; Well of the Immortal Mei, the Well of Ge Hong and the Well of the Immortal reflect harmony between local legends of Daoist immortals and the sacred Buddhist site; and the Duangu Pier accomplished its sanctification process in the course of local pilgrimage activities. By sorting out the mechanism and process of landscape sanctification and exploring the generation and renewal of landscape meaning, we can observe the logic of the construction of this sacred site

A Sextuple Cross-Coupled SRAM Cell Protected against Double-Node Upsets

International audienceIn this paper, we propose a sextuple cross-coupled SRAM cell, namely SCCS18T, protected against double-node upsets. Since the proposed SCCS18T cell forms a large feedback loop for value retention and error interception, the cell can self-recover from all possible single-node upsets (SNUs) and a part of double-node upsets (DNUs). Moreover, the proposed cell has optimized operation speed due to the use of parallel access transistors. Simulation results demonstrate that the proposed SCCS18T cell can approximately save 65% read access time at the cost of 49% power dissipation and 50% silicon area on average, compared with the state-of-the-art hardened SRAM cells
