A Fog Computing and Cloudlet Based Augmented Reality System for the Industry 4.0 Shipyard (2018)

Augmented Reality (AR) is one of the key technologies pointed out by Industry 4.0 as a tool for enhancing the next generation of automated and computerized factories. AR can also help shipbuilding operators, since they usually need to interact with information (e.g., product datasheets, instructions, maintenance procedures, quality control forms) that could be handled easily and more efficiently through AR devices. This is the reason why Navantia, one of the 10 largest shipbuilders in the world, is studying the application of AR (among other technologies) in different shipyard environments in a project called "Shipyard 4.0". This article presents Navantia's industrial AR (IAR) architecture, which is based on cloudlets and on the fog computing paradigm. Both technologies are ideal for supporting physically-distributed, low-latency and QoS-aware applications that decrease the network traffic and the computational load of traditional cloud computing systems. The proposed IAR communications architecture is evaluated in real-world scenarios with payload sizes according to demanding Microsoft HoloLens applications and when using a cloud, a cloudlet and a fog computing system. The results show that, in terms of response delay, the fog computing system is the fastest when transferring small payloads (less than 128 KB), while for larger file sizes, the cloudlet solution is faster than the others. Moreover, under high loads (with many concurrent IAR clients), the cloudlet in some cases is more than four times faster than the fog computing system in terms of response delay.
Direct reduction of copper slag-carbon composite pellets by coal and biochar (2018)

As a renewable resource of reducer, biochar prepared by pine sawdust is proposed for direct reduction of copper slag in this paper. Combined with thermodynamic analysis, effects of reduction time, temperature and CaO addition ratio on solid copper slag reduction characteristics are discussed. The oxides of iron in copper slag are Fe<sub>3</sub>O<sub>4</sub> and 2FeO·SiO<sub>2</sub>. The reduction processes were carried out step by step for Fe<sub>3</sub>O<sub>4</sub> and 2FeO·SiO<sub>2</sub>, respectively: Fe<sub>3</sub>O<sub>4 </sub>→ FeO → Fe and 2FeO·SiO<sub>2 </sub>→ Fe. The porous structure of biochar exhibits higher reduction reactivity and reaction rate than that of coal. CaO reduced the Gibbs free energy of reduction reactions and facilitated the reduction of 2FeO·SiO<sub>2</sub> with C and CO. When CaO was added, separation reaction of FeO and SiO<sub>2</sub> took place and <i>α</i>-SiO<sub>2</sub> and <i>β</i>-SiO<sub>2</sub> were produced. When the addition ratio of CaO is above 0.3, CaO·SiO<sub>2</sub> and 2CaO·SiO<sub>2</sub> are produced. The reduction process of copper slag was established as follows: (a) dehydration and fast pyrolysis; (b) reduction of iron oxides by C and CO; and (c) sweating metallic iron outflows from cracks in pellet. Besides, direct reduction reaction mechanism and transport process of Cu are established based on reduction experiments, XRD and SEM-EDS analysis.
Evaluation of glutathione-sensitive fluorescent dyes in cortical culture (2000)

The sensitivity of six fluorophores to glutathione (GSH) was evaluated in living rat cortical neuronal/glial mixed cultures during the first 23 days in vitro (DIV). Four of the dyes require glutathione-S-transferase (GST) to form a fluorescent conjugate, potentially conferring specificity for GSH: these included t-butoxycarbonyl-Leu-Met-7-amino-4-chloromethylcoumarin (CMAC), 7-amino-4-chloromethylcoumarin (CMAC-blue), monochlorobimane (MCB), and 5-chloromethylfluorescein diacetate (CMFDA). The final two dyes examined, 2,3-naphthalenedicarboxaldehyde (NDA) and o-phthaldehyde (OPD), do not require GST for adduct formation with GSH. To examine the specificity of the dyes for GSH, cultures grown less than 6 DIV were pretreated with diethyl maleate or DL-buthionine-(S, R)-sulfoximine to deplete endogenous GSH. This resulted in a substantial loss of staining by CMAC, CMAC-blue, and MCB and partial loss of staining by OPD, indicating specificity for GSH, while staining by CMFDA or NDA was not altered, indicating a lack of specificity for GSH. Neurons experienced a dramatic decline in GSH levels relative to astrocytes between 5-6 DIV, as shown by a loss of neuronal staining with CMAC, CMAC-blue and MCB. This decrease in staining was not due to a decrease in GST activity, as neurons stained with the GST-insensitive OPD also exhibited a decline in GSH-sensitive staining. Immunolabeling experiments demonstrated that CMAC staining co-localized with GFAP-positive astrocytes, but not with MAP-2-positive neurons, in 18 DIV cultures. Finally, CMAC was exploited as a specific morphological marker of astrocytes in cultures aged >5 DIV. CMAC staining was employed to monitor astrocyte proliferation and to resolve astrocytes in living mixed cultures co-loaded with the Ca(2+)-sensitive dye, calcium green 5N-AM. GLIA 30:329-341, 2000.

Multi-Level Function Specification and Architecture Analysis Using ESL: A Lock Renovation Pilot Study (2018)

In this paper, we present a pilot study to show the first proof-of-principle of the recently developed Elephant Specification Language (ESL). The Prinses Marijke locks in the Netherlands are due for a major renovation. To effectively organize the renovation project, engineers need insight into the network of dependencies between components that are due for renewal and components that remain, to ensure that the replacement parts will fit and function properly in the existing structure. ESL is used to write a structured multi-level function specification for the Prinses Marijke locks. From this specification, multi-domain matrix (MDM) models of the system architecture are automatically derived at multiple levels of granularity. These models show dependencies between components, between functions, and combinations thereof. The MDM models are used to gain insight in the system architecture, to visualize which parts of the lock system are affected by the renovation, and to determine which dependencies have to be accounted for during the renovation process. This information is required to effectively organize the renovation project.
A study on the relationship between mechanical properties and microstructure of ariake clay (1999)

This paper investigates the relationship between the mechanical properties namely unconfined compressive test, triaxial compressive test and centrifuge model test, and the microstructure of Ariake clay. Unconfined compressive test, triaxial compressive test and centrifuge model test were carried out on three types of samples, i.e. undisturbed and reconsolidated ones under 80 C and 20 C. The stress-strain curves of undisturbed specimen (UD-specimen) and high temperature specimen (HT-specimen) show brittle stress-strain characteristics while that of room temperature specimen (RT-specimen) show ductile characteristics. From the results of centrifuge model tests, a sudden failure was observed for the UD-specimen and HT-specimen, and ductile failure was found for the RT-specimen. Comparing these mechanical properties and the microstructure of Ariake clay reported before, it is clear that there is a close relationship between the stress-strain characteristics, slope failure behaviour and the microstructure of Ariake clay.
Ultrafast dynamics of semiconductor disk lasers (2017)

Passively modelocked optically pumped semiconductor disk lasers (SDLs) [1] based on InGaAs quantum wells (QWs) such as vertical external-cavity surface-emitting lasers (VECSELs) or modelocked integrated surface-emitting lasers (MIXSELs) are an appealing ultrafast laser technology for applications that require compelling combinations of short femtosecond pulses and gigahertz pulse repetition rates. Recent development of pulse shortening strategies resulted in record-short 107-fs pulses from a VECSEL [2] and 253-fs pulses from a MIXSEL [3]. However, this progress in shorter pulse durations has come with the trade-off of significantly lower optical-to-optical pump efficiency even below 1% and only moderate average output power of around 100 mW so far.

T regulatory cells and dendritic cells protect against transfusion-related acute lung injury via IL-10 (2017)

Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related fatalities and is characterized by acute respiratory distress following blood transfusion. Donor antibodies are frequently involved; however, the pathogenesis and protective mechanisms in the recipient are poorly understood, and specific therapies are lacking. Using newly developed murine TRALI models based on injection of anti-major histocompatibility complex class I antibodies, we found CD4<sup>+</sup>CD25<sup>+</sup>FoxP3<sup>+</sup> T regulatory cells (Tregs) and CD11c<sup>+</sup> dendritic cells (DCs) to be critical effectors that protect against TRALI. Treg or DC depletion in vivo resulted in aggravated antibody-mediated acute lung injury within 90 minutes with 60% mortality upon DC depletion. In addition, resistance to antibody-mediated TRALI was associated with increased interleukin-10 (IL-10) levels, and IL-10 levels were found to be decreased in mice suffering from TRALI. Importantly, IL-10 injection completely prevented and rescued the development of TRALI in mice and may prove to be a promising new therapeutic approach for alleviating lung injury in this serious complication of transfusion.
Deantiaromatization as a Driving Force in an Electrocyclic Reaction (2006)

But how does it smell? Theory and experiment support the notion that “deantiaromatization” can serve as a driving force in the 8-π-electron electrocyclization of a cyclopentadienone (see scheme; TEA=triethylamine; TFE=trifluoroethanol). The reaction proceeds in synthetically useful yields and could be applicable to the synthesis of the antiviral agent hamigeran B.
Efecto de la neurotoxicidad en la función visual de trabajadores de lavado en seco (2012)

Dry cleaning workers are exposed to organic solvents like perchlorethylene (perc). This can affect the Central Nervous System (cns), provoke neurotoxicity and associate to neuro-visual alterations related to the visual contrast sensitivity function (csf) and the loss of color vision. Objective: To determine the deficits of contrast sensitivity (csf) by spatial frequency in a group of dry cleaning workers exposed to occupational levels of perc and its relation to the neurotoxic symptoms. Materials and methods: A case and control study in 40 dry cleaning workers and in 35 regular people with no exposure to perc was done in Bogota, Colombia. The csf was evaluated using psychophysical methods; the spatial frequencies studied were 0.5, 1.0, 2.0, 4.0, 8.0 and 16.0 cpd. Neurotoxicity was evaluated with the modified questionnaire Q16. Results: Significant differences were observed in cs above 1.0cpd (p &lt; 0.05). The Spearman correlation showed a significant negative relation between the punctuation of the modified version of the Q16 questionnaire and the spatial frequencies2.0, 4.0 and 8 cpd (Spearmanp Rho &lt; 0.05) in the cases. The Mann Whitney U test showed significant differences between cases and controls for the modified Q16 questionnaire (p &lt;0.05). Conclusion: the csf was significantly lower in those exposed to perc for the spatial frequencies above 1.0 cpd. The presence of neurotoxic symptoms in dry cleaning workers is associated with losses in csf in medium and high spatial frequencies.
Exploring metastability via third harmonic measurements in single crystals of2H−NbSe2showing an anomalous peak effect (2005)

We explore the metastability effects across the order-disorder transition pertaining to the peak effect phenomenonon in critical current density $({J}_{c})$ via the first and the third harmonic ac susceptibility measurements in the weakly pinned single crystals of $2H\text{\ensuremath{-}}{\mathrm{NbSe}}_{2}$. An analysis of our data suggests that an imprint of the limiting (spinodal) temperature above which ${J}_{c}$ is path independent can be conveniently located in the third harmonic data $({\ensuremath{\chi}}_{3\ensuremath{\omega}}^{\ensuremath{'}})$.

Ultrasensitive surface-enhanced Raman scattering detection of urea by highly ordered Au/Cu hybrid nanostructure arrays (2017)

We report a simple approach to fabricate cost-effective and highly sensitive surface-enhanced Raman scattering substrates based on Au/Cu hybrid nanostructure arrays for the detection of urea, an important molecule in biological and medical fields. By effectively adjusting the gap size between neighbouring nanorods into the sub-10 nm regime, a high density of hot-spots was generated, enabling the substrates to detect urea signals at a concentration as low as 1 mM with great reproducibility.
Nanoparticle-blockage-enabled rapid and reversible nanopore gating with tunable memory (2022)

Gated protein channels act as rapid, reversible, and fully-closeable nanoscale valves to gate chemical transport across the cell membrane. Replicating or outperforming such a high-performance gating and valving function in artificial solid-state nanopores is considered an important yet unsolved challenge. Here we report a bioinspired rapid and reversible nanopore gating strategy based on controlled nanoparticle blockage. By using rigid or soft nanoparticles, we respectively achieve a trapping blockage gating mode with volatile memory where gating is realized by electrokinetically trapped nanoparticles near the pore and contact blockage gating modes with nonvolatile memory where gating is realized by a nanoparticle physically blocking the pore. This gating strategy can respond to an external voltage stimulus (∼200 mV) or pressure stimulus (∼1 atm) with response time down to milliseconds. In particular, when 1,2-diphytanoyl-sn-glycero-3-phosphocholine liposomes are used as the nanoparticles, the gating efficiency, defined as the extent of nanopore closing compared to the opening state, can reach 100%. We investigate the mechanisms for this nanoparticle-blockage-enabled nanopore gating and use it to demonstrate repeatable controlled chemical releasing via single nanopores. Because of the exceptional spatial and temporal control offered by this nanopore gating strategy, we expect it to find applications for drug delivery, biotic-abiotic interfacing, and neuromorphic computing.
The dynamics of a localized surfactant on a thin film (1990)

We investigate the flow induced by a localized insoluble surfactant on a thin film. This problem is intended to model the behaviour of the lung's thin-film lining after an aerosol droplet lands on its surface. The surfactant-induced surface-tension gradients drive convection (Marangoni convection) within the film, disrupting the film surface and causing the surfactant to spread. The surfactant may also spread on the film's surface by surface diffusion without inducing convection. Gravity provides a restoring force that decreases film disturbances. Lubrication theory is employed to derive equations that describe the evolution of the film thickness and surfactant concentration. A nonlinear surface-tension equation of state describes the relationship between the surfactant concentration and the surface tension. Solutions of the evolution equations are found numerically using the method of lines and analytically under limiting cases of small and large surface diffusivity. The results elucidate the behaviour of the thin-film/surfactant system. We find that surface-tension-induced convection creates film disturbances that increase the film thickness near the surfactant's leading edge, and thins the film in the central region. Surface diffusion causes more rapid spreading of the surfactant, and decreases the film disturbances. Gravity decreases the film disturbances by creating bi-directional flow in the form of a ring vortex. This behaviour may have implications for the delivery of medications or toxins by aerosol inhalation.
Advances in fiber access networks development: efficient resource allocation and cost effective protection (2010)

Access networks based on optical fiber can easily fulfill high bandwidth demand and cover large service areas. Fiber access networks are also scalable to meet the future capacity request. Among several alternatives, passive optical network (PON) is considered as the most promising one, because its passive point-to-multipoint architecture is characterized by relatively low deployment and operational cost. On the other hand, the passive point-to-multipoint feature in PONs also creates a number of challenges, such as efficient resource allocation and cost-effective protection. This paper provides an overview of the advances related to these two issues and points out the research topics that are still open and need to be investigated.
ARCHAEOBOTANICAL STUDIES OF ELEUSINE CORACANA SSP. CORACANA (FINGER MILLET) (1979)

Two controversial archaeological specimens of finger millet, Eleusine coracana ssp. coracana (L.) Gaertn., were examined by light and scanning electron microscopy. Identification of the material was based on morphological and anatomical comparison with laboratory carbonized grains of modern Eleusine . Seed morphology of the Indian archaeological collection did not conform with those of domesticated or wild species of Eleusine . The other archaeological collection examined is from Ethiopia. It is estimated to date back to the third millennium B.C. These well preserved inflorescence fragments were positively identified as finger millet. If the suggested date is correct, they represent the oldest archaeological record for the crop, as well as the oldest agricultural record for Africa south of the Sahara. These findings support biosystematic evidence for an East African origin of finger millet which leaves India as a secondary center of diversity.

Prevention of regimen-related toxicities after bone marrow transplantation by pentoxifylline: a prospective, randomized trial (1993)

Elevated levels of tumor necrosis factor alpha (TNF-alpha) have been reported to correlate with the development of transplant-related complications after bone marrow transplantation (BMT). In a recent phase I-II trial, oral administration of pentoxifylline (PTX), a xanthine derivative capable of downregulating TNF-alpha production in vitro, was reported to reduce morbidity and mortality in patients undergoing BMT. We conducted a prospective randomized trial of PTX therapy among 140 patients undergoing either allogeneic (n = 51) or autologous BMT (n = 89). Patients were randomized to receive (n = 70) or not receive (n = 70) oral PTX, 1,600 mg/d in four divided doses from day -8 until day + 100 post-BMT. The incidence of mucositis requiring morphine sulfate (MSO4) was similar in both groups (42.9%), with the mean number of days with MSO4 being 7.8 (SD = 3.4) in the PTX group versus 8.2 (SD = 3.4) in the control group (NS). The incidence of renal insufficiency was not affected by PTX administration (15.7% in the PTX group v 21.4% in the control group [NS]) and the highest serum creatinine value during the first 100 days post-BMT was 119 mumol/L (SD = 82.4) in the PTX group versus 103.9 mumol/L (SD = 57) in the control group (NS). The incidence of grade &gt; or = 2 graft-versus-host disease was similar in each group (11/25 [44%] in the PTX group v 12/26 [46%] in the control group). No significant difference was observed in hematologic toxicity, transfusion requirements, duration of fever, and hepatic toxicity between the treatment groups. In conclusion, our study failed to show a prophylactic effect of PTX in transplant-related toxicities after BMT. On the basis of these findings, we cannot recommend that PTX be part of early mortality and morbidity prevention programs after BMT.

Oil Spills: Barrel‐Shaped Oil Skimmer Designed for Collection of Oil from Spills (Adv. Mater. Interfaces 15/2015) (2015)

A barrel-shaped oil-skimmer composed of a superhydrophobic-superoleophilic Cu foam and a glass barrel has been developed to separate oil and water. In article number 1500350, W. J. Xu and co-workers demonstrate that the device quickly and selectively absorbs and collects a variety of oils from a polluted water surface, showing a high separation efficiency and volume-based absorption capacity. It also shows good storage stability; no oil escapes from the skimmer under harsh conditions.
