A Simple Algorithm for Global Data Flow Analysis Problems (1975)

A simple, iterative bit propagation algorithm for solving global data flow analysis problems such as “available expressions” and “live variables” is presented and shown to be quite comparable in speed to the corresponding interval analysis algorithm. This comparison is facilitated by a result relating two parameters of a reducible flow graph (rfg). Namely, if G is an rfg, d is the largest number of back edges found in any cycle-free path in G, and k is the length of the interval derived sequence of G, then $k \geqq d$. (Intuitively, k is the maximum nesting depth of loops in a computer program, while d is a measure of the maximum loop-interconnectedness.) The node ordering employed by the simple algorithm is the reverse of the order in which a node is last visited while growing any depth-first spanning tree of the flow graph. In addition, a dominator algorithm for an rfg is presented which takes O(edges) bit vector steps.

Stable Two‐Legged Parent Piano‐Stool and Mixed Diborabenzene‐E4 (E=P, As) Sandwich Complexes of Group 8 (2022)

A cyclic alkyl(amino)carbene-stabilized 1,4-diborabenzene (DBB) ligand enables the isolation of 18-electron two-legged parent piano-stool Fe<sup>0</sup> and Ru<sup>0</sup> complexes, [(η<sup>6</sup> -DBB)M(CO)<sub>2</sub> ], the ruthenium complex being the first of its kind to be structurally characterized. [(η<sup>6</sup> -DBB)Fe(CO)<sub>2</sub> ] reacts with E<sub>4</sub> (E=P, As) to yield mixed DBB-cyclo-E<sub>4</sub> sandwich complexes with planar E<sub>4</sub> <sup>2-</sup> ligands. Computational analyses confirm the strong electron-donating capacity of the DBB ligand and show that the E<sub>4</sub> ligand is bound by four equivalent Fe-P σ bonds.
Edge-filter technique and dominant frequency analysis for high-speed railway monitoring with fiber Bragg gratings (2016)

Structural health and operation monitoring are of growing interest in the development of railway networks. Conventional systems of infrastructure monitoring already exist (e.g. axle counters, track circuits) but present some drawbacks. Alternative solutions are therefore studied and developed. In this field, optical fiber sensors, and more particularly fiber Bragg grating (FBG) sensors, are particularly relevant due to their immunity to electromagnetic fields and simple wavelength-division-multiplexing capability. Field trials conducted up to now have demonstrated that FBG sensors provide useful information about train composition, positioning, speed, acceleration and weigh-in-motion estimations. Nevertheless, for practical deployment, cost-effectiveness should be ensured, specifically at the interrogator side that has also to be fast (>1 kHz repetition rate), accurate (~1 pm wavelength shift) and reliable. To reach this objective, we propose in this paper to associate a low cost and high-speed interrogator coupled with an adequate signal-processing algorithm to dynamically monitor cascaded wavelength-multiplexed FBGs and to accurately capture the parameters of interest for railway traffic monitoring. This method has been field-tested with a Redondo Optics Inc. interrogator based on the well-known edge-filter demodulation technique. To determine the train speed from the raw data, a dominant frequency analysis has been implemented. Using this original method, we show that we can retrieve the speed of the trains, even when the time history strain signature is strongly affected by the measurement noise. The results are assessed by complimentary data obtained from a spectrometer-based FBG interrogator.
Micromechanical relay with electrostatic actuation and metallic contacts (1999)

In this paper, an improved design of an electrostatic polysilicon microrelay with metallic contacts is presented. The polysilicon layer is used for the actuator while the nickel and gold layers are used for the contacts. Improved contact resistance is demonstrated, as well as the efficiency of multiple contact bars. Moreover, by integrating nickel bars, electromagnetic actuation was successfully performed.
Surface Structure and High-Voltage Charging/Discharging Performance of Low-Content Zr-Oxide-Coated LiNi1/3Co1/3Mn1/3O2 (2015)

The surface structures, high-voltage charging/discharging performances, and Li-ion transfer at the electrode/electrolyte interface of LiNi1/3Co1/3Mn1/3O2 coated with small amounts of Zr oxide by the sol-gel method were investigated. Island-like ZrO2 grains as well as grain-free (sea-like) zones were observed on the surfaces of the coated LiNi1/3Co1/3Mn1/3O2 samples. The ratio of the area of these sea-like zones to the total surface area of the LiNi1/3Co1/3Mn1/3O2 sample increased from 44 to 85% when the Zr oxide content was decreased from 1.0 to 0.125 wt%. A compound oxide phase containing Zr, Ni, Co, and Mn was formed uniformly on the sea-like zones; the depth of this phase was approximately 2 nm. The initial discharge capacities of the coated LiNi1/3Co1/3Mn1/3O2 samples were equal to that of bare LiNi1/3Co1/3Mn1/3O2. Further, the cycling performances of the coated LiNi1/3Co1/3Mn1/3O2 samples were significantly higher, as were their discharge capacities and discharge voltages, while their charge-transfer resistances (Rct) were lower. It was also found that the coated LiNi1/3Co1/3Mn1/3O2 samples had lower activation energies (Ea) for charge transfer than the bare LiNi1/3Co1/3Mn1/3O2. Thus, it can be surmised that the area and structure of the sea-like zones determined the Rct and Ea values and cycling performances of the coated LiNi1/3Co1/3Mn1/3O2 samples.
Metastable Fe nitrides with high Bs prepared by reactive sputtering (1982)

Preparation of thick films or bulk formed materials of Fe16N2 compound has been attempted using a high rate reactive-sputtering technique. As for the reactive gas, N2 was introduced with various pressures (PN2) into the chamber by mixing with Ar gas of about 10−2 Torr. About 0.5-mm thick bulk deposits were obtained through the continuous running with a 1000 Å/min rate. It has been found that the magnetization (σs) of about 240 emu/g exceeding the value for Fe can be obtained around PN2=0.1∼1×10−3 Torr. From thermomagnetization and x-ray analyses the increased σs is attributed to Fe16N2 compound, but the coexistence of bcc Fe and Fe4N prevents reaching the σs to the expected maximum value 298 emu/g of Fe16N2. From the application point of view, the presently obtained Fe nitrides are interesting in their coercivities and are useful for semihard magnets with high Vicker’s hardness (about 700 Hv).

Epstein-Barr virus modulates de novo protein synthesis in human neutrophils (1995)

Neutrophils and macrophages represent the first line of defense against microbial invaders. However, the role of phagocytes in host response to viral infection is poorly understood. We have previously shown that Epstein-Barr virus (EBV) interacts with human monocytes and modulates cytokine production in this cell type, but its effects on neutrophils are still unknown. In the present study, we investigated the presence of EBV receptor (CR2 or CD21) on neutrophils by cytofluorometry using five different anti-CD21 monoclonal antibodies (MoAbs), as well as fluoroscein isothiocyanate-EBV (FITC-EBV). Whereas no significant amount of neutrophils reacted with anti-CD21 MoAbs, studies with FITC-EBV indicated that viral particles bind to 30% of cells (in some individuals, EBV binds to more than 50% of neutrophils). This interaction is specific as it was completely inhibited by nonconjugated virus or with labeled virus preincubated with neutralizing MoAbs. After EBV treatment, cellular aggregation was observed in neutrophil cultures, an indication that neutrophils were activated. Although EBV did not induce respiratory burst activity in neutrophils, pretreatment with infectious particles enhanced (priming effect) the fMLP-induced O2-release in neutrophils. Instead of restricting our analysis to specific cytokine genes, we investigated the effects of EBV on neutrophil transcriptional events in general. The effect of this virus on de novo synthesis of total cellular RNA was first investigated by measuring the incorporation of [5–3H] uridine into total RNA. The results showed that RNA synthesis in neutrophils was significantly increased (2.3- to 21.3-fold) by EBV compared with the unstimulated controls. Live and UV-inactivated virus markedly induced RNA synthesis, whereas heat-inactivated virus lost this ability. Induction of RNA transcription was EBV specific, as an EBV-neutralizing antiserum abolished this effect. Induction of protein synthesis was also studied by measuring the incorporation of [35S] methionine and [35S] cysteine into secreted and intracellular proteins in neutrophils incubated with EBV. The synthesis of both secreted and cytoplasmic proteins was induced by EBV. One- and two-dimensional gel electrophoresis analysis showed that EBV modulates protein synthesis, because activation of the synthesis of certain proteins was accompanied by the inhibition of others. Interleukin-1 beta (IL-1 beta) and IL-1 receptor antagonist (IL-1Ra) synthesis was found to be induced by EBV. Therefore, modulation of host-response proteins such as IL-1Ra could be one of the many mechanisms by which this virus avoids rejection.(ABSTRACT TRUNCATED AT 400 WORDS)
The Infection Attack Rate and Severity of 2009 Pandemic H1N1 Influenza in Hong Kong (2010)

Almost half of all school-aged children in Hong Kong were infected during the first wave. Compared with school children aged 5-14 years, older adults aged 50-59 years had 9.5 and 66 times higher risks of ICU admission and death if infected, respectively.
Experimental results from fast electron pattern generator: A variable shaped beam machine (1986)

Fast electron pattern generator (FEPG) is a variable shaped beam lithographic system specially designed for direct writing on wafers and for mask fabrication. Experimental results are given: gold gratings on silicon patterned with 10×0.3 μm spots, 1 μm gate field-effect transistor (FET), masks 1×. All these results performed with a 5 A/cm2 current density are consistent with a 1 μm technology. When the spot current exceeds 5 A/cm2, defects due to the space charge effect appear. Thermal effects on glass substrates are pointed out.
Über die Inhaltsstoffe des grünen Knollenblätterpilzes, LV. Über Peptidsynthesen, LXII. Die Isolierung, Charakterisierung und Totalsynthese von Prophalloin (Pro4‐phalloin), einem ungiftigen vermutlichen Vorläufer der Phallotoxine (1978)

Abstract Es wird über Isolierung, Charakterisierung und Totalsynthese eines in geringer Menge im Methanolextrakt von Amanita phalloides enthaltenen Vertreters der Phalloidinfamilie berichtet: Prophalloin ( 1d ), eine ungiftige Komponente, enthält anstelle des allo ‐Hydroxyprolins von Phalloin ( 1a ) in 4‐Stellung Prolin. Die Kopplung des S ‐Chlorids von Boc‐Alanyl‐D‐threonyl‐cysteinylprolin ( 5 ) mit Alanyl‐tryptophyl‐γ‐hydroxyleucinlacton liefert den Thioether 6 , dessen Cyclisierung Boc‐geschütztes Secoprophalloinlacton 7 ergibt. Boc‐Abspaltung, Öffnung des Lactonrings und zweite Cyclisierung führten zu Prophalloin ( 1d ), das in seinen biologischen und spektroskopischen Eigenschaften mit dem Naturstoff identisch ist.
Beyond the numbers of maternal near-miss in Rwanda – a qualitative study on women’s perspectives on access and experiences of care in early and late stage of pregnancy (2016)

Improved service provision routines, information, and amendments to the insurance system are suggested to enhance prompt care-seeking. Additionally, we strongly recommend a health system that considers the needs of all pregnant women, especially those facing unintended pregnancies or complications in the early stages of pregnancy.
MIMO SLIDING-MODE AND H∞ CONTROLLER DESIGN FOR DYNAMIC COUPLING REDUCTION IN UNDERWATER-MANIPULATOR SYSTEMS (2009)

In underwater remote vehicle-manipulator system (URVM) applications, it is beneficial to have the underwater remote vehicle (URV) hold station using its thrusters while a human pilot operates the serial manipulator. This provides a stable platform for the manipulator and eases the pilot’s job drastically when current and/or tether disturbances are present. The contribution of this work is twofold: Firstly, the reduction of dynamic coupling in the URVM systems is realized using two robust control techniques namely Sliding-mode control and H ∞ control, and the performance of both controllers in the dynamic coupling reduction problem is reported. Secondly, a new control scheme is proposed that involves both controllers in the control loop. Numerical case studies are developed to demonstrate the effectiveness of the controllers. It is concluded that sliding-mode and H ∞ controller combined approach provides superior dynamic coupling reduction performance.
Impact-triggered thermoelectric power generator using phase change material as a heat source (2013)

This paper demonstrates an impact-triggered thermoelectric generator that uses latent heat liberated from the crystallization of supersaturated sodium acetate trihydrate (SSAT). A volume of SSAT is encapsulated in a polydimethylsiloxane chamber and capped with a steel plate. The device triggers when an external impact is applied to the steel plate, leading to an exothermic crystallization process. The heat creates a thermal gradient across a thermoelectric module which in turn generates electrical output. A maximum hot-junction temperature of 58 °C can be achieved, resulting in an instantaneous output power of 2.08 mW across 185 Ω load using a 3.3×2.5×1 mm3 commercially available Bi2Te3 thermoelectric module with 290 junctions.
Safety and Efficacy of Microfocused Ultrasound to Lift, Tighten, and Smooth the Buttocks (2014)

Although microfocused ultrasound clearly can be used to safely lift, tighten, and smooth the buttocks, better subject selection and newer developed transducers may lead to greater overall acceptance of this technique.
Isolated azygos continuation of the inferior vena cava. (1979)

Our case of azygos continuation of the inferior vena cava is very rare because there was no associated heart disease or abdominal situs inversus. The diagnosis of this anomaly of the inferior vena cava should be suspected by observation of a dilated azygos vein on the chest roentgenogram and confirmed by venography.
Streptococcus australis and Ralstonia pickettii as Major Microbiota in Mesotheliomas (2021)

The microbiota has been reported to be correlated with carcinogenesis and cancer progression. However, its involvement in the pathology of mesothelioma remains unknown. In this study, we aimed to identify mesothelioma-specific microbiota using resected or biopsied mesothelioma samples. Eight mesothelioma tissue samples were analyzed via polymerase chain reaction (PCR) amplification and 16S rRNA gene sequencing. The operational taxonomic units (OTUs) of the effective tags were analyzed in order to determine the taxon composition of each sample. For the three patients who underwent extra pleural pneumonectomy, normal peripheral lung tissues adjacent to the tumor were also included, and the same analysis was performed. In total, 61 OTUs were identified in the tumor and lung tissues, which were classified into 36 species. <i>Streptococcus australis</i> and <i>Ralstonia pickettii</i> were identified as abundant species in almost all tumor and lung samples. <i>Streptococcus australis</i> and <i>Ralstonia pickettii</i> were found to comprise mesothelioma-specific microbiota involved in tumor progression; thus, they could serve as targets for the prevention of mesothelioma.
Cross Conjugated Polyenes Derived from 2‐Vinyl‐butadiene: Electronic States of their Radical Cations, and Triplet Energy (1983)

Abstract The doublet states of the radical cations of the cross conjugated polyenes 4,4‐dimethyl‐1‐methylidene‐2,5‐cyclohexadiene 2 and its bis‐derivative 1 have been investigated by photoelectron spectroscopy and by electronic spectroscopy of \documentclass{article}\pagestyle{empty}\begin{document}$ \rm {1}^{+\kern-4pt {.} } $\end{document} + , prepared at 77 K in an electron scavenging matrix by γ‐irradiation. Simultaneous consideration of the spectral results shows \documentclass{article}\pagestyle{empty}\begin{document}$ \rm {1}^{+\kern-4pt {.} } $\end{document} to be the second hydrocarbon molecular cation (after 2,2‐dimethyl isoindene) which possesses a first excited doublet state (D 1 ) of non‐ Koopmans nature ( 2 B 3g ). The first Koopmans ‐type excited state ( 2 B 2g ) expected from PE. spectroscopy lies, however, very close in energy. In addition T 1 of 1 was observed by electron energy loss spectroscopy at 2.0±0.1 eV. Application of the ‘SDT‐equation’ predicts for this state only 1.05 eV; there is at present no reasonable explanation for this failure.

Phylogeny of the Eucoilinae (Hymenoptera: Cynipoidea: Figitidae) (2002)

The Eucoilinae are a diverse and important group of parasitoids of Diptera, particularly in the tropics, but they are poorly known systematically and their generic classification is partly chaotic. Here, we present the first comprehensive cladistic analysis of higher eucoiline relationships. The analysis is based on 148 skeletal characters of adults documented in more than 1100 digital images available in an Internet-accessible database. The characters were coded for 45 taxa representing 35 eucoiline genera, spanning the entire diversity of the group, and 7 outgroup genera. Relationships were partly difficult to resolve and parsimony analysis under implied weights performed considerably better than analysis under uniform weights. The results support the monophyly of the Eucoilinae and show that eucoilines are most closely related to the figitid subfamilies Emargininae and Pycnostigminae, but are ambiguous concerning the exact relationships among these three lineages. Of the 6 eucoiline genus groups recognized by Nordlander in 1982 (Entomol. Scand. 13, 269–292), only 2 are supported as monophyletic: the Trybliographa and Kleidotoma groups. The Gronotoma group is a paraphyletic assemblage of two different basal clades of eucoilines. The Rhoptromeris group is unnatural and only the 2 core genera, Rhoptromeris and Trichoplasta, form a monophyletic lineage. The data are ambiguous concerning the Ganaspis group, which appears to be paraphyletic, and the Chrestosema group, which may be a good clade. Based on the results we propose a modified system of informal genus groups in the Eucoilinae and discuss putative synapomorphies supporting each genus group. The proposed relationships imply that the first eucoilines were parasitoids of leaf-mining agromyzids. The earliest split in the group was apparently between an Afrotropical and a Neotropical lineage, and much of the early radiation of the group occurred in these regions, particularly in the Neotropics.
Evaluating energy efficiency from the perspective of clean energy and carbon emission (2022)

Improving energy efficiency and optimizing energy structure is the key to achieving the “dual carbon” goal and high-quality development. This paper calculates the energy efficiency of 30 provinces in China between 2000 and 2017 using the DEA method. The study found that in China, the energy efficiency is higher in East China than in West China, in South China than in North China, and in the coastal areas than in the interior. Moreover, the efficiency gap between clean fuel and fossil fuel is widening. Taking total power consumption as energy input and measuring carbon emissions using regional grid base line emission factor can accurately measure China’s clean energy efficiency. The conclusions of the study provide important references for promoting China’s energy transformation and the development of the green economy.
DVMM: A Distributed VMM for Supporting Single System Image on Clusters (2008)

Providing single system image (SSI) on clusters has ever been one of the hot topics in the research field of parallel computer architecture, since SSI supports easier programming and administration on clusters. Currently, most SSI studies focus on the middleware level of clusters, leading to some problems of poor transparence, low performance and so on. This paper presents a novel solution to provide SSI on clusters using a distributed virtual machine monitor (DVMM) with hardware-assisted virtualization technologies. The DVMM contains some symmetrical and cooperative VMMs distributed on multi-node. The cooperation among the VMMs virtualizes the distributed hardware resources to support SSI on a cluster. Thus, the DVMM can support an unmodified legacy operating system (OS) to run transparently on a cluster. Compared with the related work, our solution has some advantages of good transparence, high performance and easy implementation.
