<title>Perceptual issues in augmented reality</title> (1996)

Between the extremes of real life and Virtual Reality lies the spectrum of Mixed Reality, in which views of the real world are combined in some proportion with views of a virtual environment. Combining direct view, stereoscopic video, and stereoscopic graphics, Augmented Reality describes that class of displays that consists primarily of a real environment, with graphic enhancements or augmentations. Augmented Virtuality describes that class of displays that enhance the virtual experience by adding elements of the real environment. All Mixed Reality systems are limited in their capability of accurately displaying and controlled all relevant depth cues, and as a result, perceptual biases can interfere with task performance. In this paper we identify and discuss eighteen issues that pertain to Mixed Reality in general, and Augmented Reality in particular.

Activation of AtMPK9 through autophosphorylation that makes it independent of the canonical MAPK cascades (2015)

Mitogen-activated protein kinases (MAPKs) are part of conserved signal transduction modules in eukaryotes that are typically organized into three-tiered kinase cascades. The activation of MAPKs in these pathways is fully dependent on the bisphosphorylation of the TXY motif in the T-loop by the pertinent dual-specificity MAPK kinases (MAPKKs). The Arabidopsis mitogen-activated protein kinase 9 (AtMPK9) is a member of an atypical class of MAPKs. Representatives of this MAPK family have a TDY phosphoacceptor site, a long C-terminal extension and lack the common MAPKK-binding docking motif. In the present paper, we describe multiple in vitro and in vivo data showing that AtMPK9 is activated independently of any upstream MAPKKs but rather is activated through autophosphorylation. We mapped the autophosphorylation sites by MS to the TDY motif and to the C-terminal regulatory extension. We mutated the phosphoacceptor sites on the TDY, which confirmed the requirement for bisphorylation at this site for full kinase activity. Next, we demonstrated that the kinase-inactive mutant form of AtMPK9 is not trans-phosphorylated on the TDY site when mixed with an active AtMPK9, implying that the mechanism of the autocatalytic phosphorylation is intramolecular. Furthermore, we show that in vivo AtMPK9 is activated by salt and is regulated by okadaic acid-sensitive phosphatases. We conclude that the plant AtMPK9 shows similarities to the mammalian atypical MAPKs, such as extracellular-signal-regulated kinase (ERK) 7/8, in terms of an MAPKK-independent activation mechanism.
Genetic lineage tracing analysis of the cell of origin of hepatotoxin‐induced liver tumors in mice (2016)

The expression of biliary/progenitor markers by hepatocellular carcinoma (HCC) is often associated with poor prognosis and stem cell‐like behaviors of tumor cells. Hepatocellular adenomas (HCAs) also often express biliary/progenitor markers and frequently act as precursor lesions for HCC. However, the cell of origin of HCA and HCC that expresses these markers remains unclear. Therefore, to evaluate if mature hepatocytes give rise to HCA and HCC tumors and to understand the molecular pathways involved in tumorigenesis, we lineage‐labeled hepatocytes by injecting adeno‐associated virus containing thyroxine‐binding globulin promoter‐driven causes recombination ( AAV‐TBG‐Cre ) into RosaYFP mice. Yellow fluorescent protein (YFP) was present in &gt;96% of hepatocytes before exposure to carcinogens. We treated AAV‐TBG‐Cre ; RosaYFP mice with diethylnitrosamine (DEN), followed by multiple injections of carbon tetrachloride to induce carcinogenesis and fibrosis and found that HCA and HCC nodules were YFP + lineage‐labeled; positive for osteopontin, SRY (sex determining region Y)‐box 9, and epithelial cell adhesion molecule; and enriched for transcripts of biliary/progenitor markers such as prominin 1, Cd44, and delta‐like 1 homolog. Next, we performed the converse experiment and lineage‐labeled forkhead box protein L1(Foxl1)‐positive hepatic progenitor cells simultaneously with exposure to carcinogens. None of the tumor nodules expressed YFP, indicating that Foxl1‐expressing cells are not the origin for hepatotoxin‐induced liver tumors. We confirmed that HCA and HCC cells are derived from mature hepatocytes and not from Foxl1‐Cre ‐marked cells in a second model of toxin‐induced hepatic neoplasia, using DEN and 3,3′,5,5′‐tetrachloro‐1,4‐bis(pyridyloxy)benzene (TCPOBOP). Conclusion : Hepatocytes are the cell of origin of HCA and HCC in DEN/carbon tetrachloride and DEN/TCPOBOP induced liver tumors. (H epatology 2016;64:1163‐1177)
Preferential Transfer of Certain Plasma Membrane Proteins onto T and B Cells by Trogocytosis (2010)

T and B cells capture antigens via membrane fragments of antigen presenting cells (APC) in a process termed trogocytosis. Whether (and how) a preferential transfer of some APC components occurs during trogocytosis is still largely unknown. We analyzed the transfer onto murine T and B cells of a large panel of fluorescent proteins with different intra-cellular localizations in the APC or various types of anchors in the plasma membrane (PM). Only the latter were transferred by trogocytosis, albeit with different efficiencies. Unexpectedly, proteins anchored to the PM's cytoplasmic face, or recruited to it via interaction with phosphinositides, were more efficiently transferred than those facing the outside of the cell. For proteins spanning the PM's whole width, transfer efficiency was found to vary quite substantially, with tetraspanins, CD4 and FcRgamma found among the most efficiently transferred proteins. We exploited our findings to set immunodiagnostic assays based on the capture of preferentially transferred components onto T or B cells. The preferential transfer documented here should prove useful in deciphering the cellular structures involved in trogocytosis.
Impact of LoRa Imperfect Orthogonality: Analysis of Link-Level Performance (2018)

In this letter, we focus on the evaluation of link-level performance of LoRa technology, in the usual network scenario with a central gateway and high-density deployment of end-devices. LoRa technology achieves wide coverage areas, low power consumption and robustness to interference thanks to a chirp spread-spectrum modulation, in which chirps modulated with different spreading factors (SFs) are quasi-orthogonal. We focus on the performance analysis of a single receiver in presence of collisions. First, we analyze LoRa modulation numerically and show that collisions between packets modulated with different SFs can indeed cause packet loss if the interference power received is strong enough. Second, we validate such findings in experiments based on commercial devices and software-defined radios. Contradicting the common belief that SFs can be considered orthogonal, our results demonstrate that inter-SF collisions are indeed an issue in LoRa networks and, thus, allocating higher SFs to users far from the gateway might not necessarily improve their link capacity, in case of congested networks.

Streptococcus pyogenes Fibronectin-binding Protein F2 (2004)

Some Streptococcus pyogenes (group A streptococci, GAS) strains have previously been shown to express the fibronectin-binding protein F2 instead of the functionally related but structurally dissimilar protein F1/SfbI. In this study, recombinant N-terminal and C-terminal portions and the two fibronectin-binding domains of protein F2 were used to assess affinity parameters of the interaction with fibronectin and its N-terminal 70-, 30-, and 45-kDa fragments. The association and dissociation equilibrium constants for both binding domains were in the nanomolar range, although the repeat domain of protein F2 exceeded the affinity of the unique domain by up to one order magnitude. Both domains primarily interacted with the 30-kDa fibronectin fragment. Using a prtF2 gene isogenic mutant of a serotype M49 GAS strain that does not harbor the protein F1/SfbI gene, the attachment values of whole bacteria to immobilized fibronectin and to HEp-2 epithelial cells were found to be 6- and 2-fold decreased, respectively. Reduction of prtF2 mutant internalization rates for eukaryotic cells exceeded the reduction of attachment rates, indicating an independent contribution of protein F2 to both processes. The prtF2 transcription and protein F2 expression profiles documented maximum expression at the transition to the stationary phase especially under aerobic growth condition. The protein F2 function as the major fibronectin-binding adhesin in a subset of GAS strains, its expression pattern, and highly specific interaction with fibronectin would be consistent with a status as an indispensable virulence factor for both earlier and later pathogenetic stages of GAS superficial infections.
A physical method for measuring speech-transmission quality (1980)

A physical method for measuring the quality of speech-transmission channels has been developed. Essentially, the method represents an extension of the Articulation Index (AI) concept, which was developed mainly to account for distortions in the frequency domain (noise, bandpass-limiting). The underlying concept of the present approach, based on the Modulation Transfer Function (MTF) of a transmission channel, has been adapted to account for nonlinear distortions (peak clipping) as well as for distortions in the time domain (reverberation, echoes, AGC). The resulting index, the Speech-Transmission Index (STI), has been correlated with subjective intelligibility scores obtained on 167 different transmission channels with a wide variety of disturbances. The relative predictive power of the STI, expressed in PB-word score, appeared to be 5%. This accuracy is comparable with results obtained from subjective measurements when about four talkers and four listeners are used. Expressed in terms of signal-to-noise ratio, the accuracy is about 1 dB. Pilot studies have been carried out to evaluate the use of the STI for testing digital-speech transmission channels.
Mechanical Properties of Continuous-Cast and Hot Direct-Rolled Ti-added High Strength Steel Sheets (1988)

Continuous-cast and hot direct-rolling processes(CC-HDR) have been under operation in Japan and contributed to saving energy and time.From a metallurgical point of view, some differences of mechanical properties of low alloyed steels may take place between CC-HDR and conventional reheat-rolling process (Reheat), because of its change in dissolution and precipitation behavior of the alloying elements.Mechanical properties of Ti-added high strength hot rolled steel sheets manufactured by CC-HDR in Sakai Works, Nippon Steel Corp., have been examined in comparison with those of conventional Reheat steels.Both of the tensile and yield strength of the HDR steel sheets, having 55 and 60 kgf/mm2 tensile strengths level, were 45 kgf/mm2 higher than those of Reheat steels. The amount of H3PO4(2+1) soluble Ti of HDR steels were larger than that of Reheat steels and the number of relatively coarse Ti-precipitates measured by TEM were few in comparison with that of Reheat steels.Therefore it is concluded that the amount of very small size Ti-precipitates in HDR steels which contribute to the strength of steel may probably be larger than that of Reheat steels and so the strength of HDR steels are higher than that of Reheat steels. This difference of precipitation behavior between these processes was explained by their different thermal histories.

Semi-supervised feature selection via multiobjective optimization (2006)

In previous work, we have shown that both unsupervised feature selection and the semi-supervised clustering problem can be usefully formulated as multiobjective optimization problems. In this paper, we discuss the logical extension of this prior work to cover the problem of semi-supervised feature selection. Our extensive experimental results provide evidence for the advantages of semi-supervised feature selection when both labelled and unlabelled data are available. Moreover, the particular effectiveness of a Pareto-based optimization approach can also be seen.

Hollow Titania Spheres from Layered Precursor Deposition on Sacrificial Colloidal Core Particles (2001)

The preparation of monodisperse hollow titania spheres with defined diameter, wall thickness, and crystal phase by the layer-by-layer templating of colloid particles and subsequent calcination (see Figure) is reported. A major advantage associated with this type of colloid templating is that it can be conducted from any aqueous solution. Nanometer-level control over the sphere wall thickness is achieved by varying the number of layers deposited on the particles.
Chip-scale demonstration of hybrid III–V/silicon photonic integration for an FBG interrogator (2017)

Silicon photonic integration is a means to produce an integrated on-chip fiber Bragg grating (FBG) interrogator. The possibility of integrating the light source, couplers, grating couplers, de-multiplexers, photodetectors (PDs), and other optical elements of the FBG interrogator into one chip may result in game-changing performance advances, considerable energy savings, and significant cost reductions. To the best of our knowledge, this paper is the first to present a hybrid silicon photonic chip based on III–V/silicon-on-insulator photonic integration for an FBG interrogator. The hybrid silicon photonic chip consists of a multiwavelength vertical-cavity surface-emitting laser array and input grating couplers, a multimode interference coupler, an arrayed waveguide grating, output grating couplers, and a PD array. The chip can serve as an FBG interrogator on a chip and offer unprecedented opportunities. With a footprint of 5  mm×3  mm, the proposed hybrid silicon photonic chip achieves an interrogation wavelength resolution of approximately 1 pm and a wavelength accuracy of about ±10  pm. With the measured 1 pm wavelength resolution, the temperature measurement resolution of the proposed chip is approximately 0.1°C. The proposed hybrid silicon photonic chip possesses advantages in terms of cost, manufacturability, miniaturization, and performance. The chip supports applications that require extreme miniaturization down to the level of smart grains.
Effect of the sterilization process on physical and mechanical properties of the Bonacryl bone cement (2008)

The use of bone cements of poly(methyl methacrylate) (PMMA) to fix artificial prosthesis to the human body is a habitual method in orthopedic surgery. The hip and the knee joints have a very complex biomechanics and support high loads, for these reasons, acrylic bone cements have to comply with international standards in order to secure the biofuncionality and durability of the implant. In this work we report the effect of sterilization by ethylene oxide or gamma radiation on the BONACRYL Cuban cement. We determined how sterilization methods affect the molecular weight of the polymer as well as its quasi-static mechanical properties. The results demonstrated that the gamma radiation modifies the molecular weight of the PMMA although the compression and bending strength were not affected by the sterilization process applied.

Terbium‐Catalyzed Selective Area Growth of SiC Nanorods: Synthesis, Optimal Growth, and Field Emission Properties (2009)

The purpose of this work is to elucidate the selective area growth of SiC nanorods on the electrospun nanofibers catalyzed by terbium metals, and further explore the optimal growth conditions and field emission properties in this case. X‐ray diffraction, Raman spectroscopy, field‐emission scanning electron microscopy, and transmission electron microscopy were used to investigate the growth mechanism. Test results indicated that our experimental process should be an organic whole and each aspect is indispensable. Furthermore, our work finished up with excellent field emission results, showing a rather low E to of 8 V/μm and a large β value of 904.
High-flow nasal oxygen for suspension laryngoscopy: a multicenter open-label study (2022)

In this study, we aimed to assess the efficacy of high-flow nasal oxygen (HFNO) to maintain blood peripheral oxygen saturation (SpO2) in patients undergoing suspension laryngoscopy under general anesthesia. Adult patients were included in this bicenter study. After face-mask oxygenation, HFNO at a flow rate of 70 L min<sup>-1</sup> and fraction of inspired oxygen 100% was initiated at loss of consciousness. At the end of HFNO, blood gas analysis was performed. Of the 29 included patients, five (17.2%; 95% confidence interval [CI]: 7.6-34.5) presented SpO2 <95% during the first 15 minutes of the procedure and eight patients (27.6%; 95% CI: 14.7-45.7) presented SpO2 <95% throughout the procedure. Six patients (20.7%; 95% CI: 9.8-38.4) required rescue jet ventilation. Median apnea time before SpO2 <95% was 13.5 (interquartile range [IQR]: 10-17.7) minutes. Arterial carbon dioxide tension at the end of the procedure or at the time of study discontinuation was 9.73 (IQR: 8.8-10.9) kPa and was higher than 8 kPa in 88.9% (95% CI: 71.9-96.1) of patients. HFNO was associated with a relatively high incidence of suboptimal oxygen saturation and hypercapnia during suspension laryngoscopy under general anesthesia and may not be considered the reference technique.

Ceramides of pig epidermis: structure determination (1983)

Seven distinguishable groups of ceramides have been isolated from pig epidermis and identified. In order of increasing polarity there are: 1, N-(omega-acyloxy)acylsphingosines (7.7%); 2, N-acylsphingosines (42.4%); 3, N-acylphytosphingosines (10.2%); 4, N-(alpha-hydroxy)acylsphingosines (12,1%); 5, N-(alpha-hydroxy)acylsphingosines (10.5%); 6a, N-[omega-(alpha-hydroxy)acyloxy]acylsphingosines (1.7%); 6b, N-(alpha-hydroxy)-acylphytosphingosines (15.5%). In ceramide 5, the alpha-hydroxyacid moieties are predominantly C16, whereas in ceramides 4, 6a, and 6b, the alpha-hydroxyacids are mainly C24-C28. The omega-hydroxyacids in ceramides 1 and 6a are mainly C30-C32. In ceramide 1, the fatty acids esterified to the omega-hydroxyl group contain a high proportion of linoleic acid (74.5%). These ceramides apparently form a large proportion of the intercellular lipid lamellae in the epidermal stratum corneum, which are thought to constitute the barrier to water loss.
Synthesis and characterization of donor–bridge–acceptor alternating copolymers containing perylene diimide units and their application to photovoltaic cells (2010)

Abstract We have used Suzuki coupling to prepare a series of alternating copolymers featuring coplanar cyclopentadithiophene and hole‐transporting carbazole units. We observed quenching in the photoluminescence spectra of our polymers after incorporating pendent electron‐deficient perylene diimide ( PDI ) moieties on the side chains, indicating more efficient photoinduced electron transfer. Electrochemical measurements revealed that the PDI ‐containing copolymers displayed reasonable and sufficient offsets of the energy levels of their lowest unoccupied molecular orbitals for efficient charge dissociation. The performance of bulk heterojunction photovoltaic cells incorporating the copolymer/[6,6]‐phenyl‐C 61 ‐butyric acid methyl ester blends (1:4, w/w) was optimized when the active layer had a thickness of 70 nm. The photocurrents of the devices were enhanced as a result of the presence of the PDI moieties, thereby leading to improved power conversion efficiencies. © 2010 Wiley Periodicals, Inc.

3-axis vibration performance of a compact sapphire microwave oscillator (2002)

The performance of a compact sapphire microwave oscillator under vibration is measured in three orthogonal axes, and net vibration sensitivity is determined as less than 5 /spl times/ 10/sup -10/ per g. This result is compared with the vibration sensitivity of other oscillator technologies reported in the literature, together with other important oscillator characteristics.
