Pore-scale modelling and sensitivity analyses of hydrogen-brine multiphase flow in geological porous media (2021)

Underground hydrogen storage (UHS) in initially brine-saturated deep porous rocks is a promising large-scale energy storage technology, due to hydrogen's high specific energy capacity and the high volumetric capacity of aquifers. Appropriate selection of a feasible and safe storage site vitally depends on understanding hydrogen transport characteristics in the subsurface. Unfortunately there exist no robust experimental analyses in the literature to properly characterise this complex process. As such, in this work, we present a systematic pore-scale modelling study to quantify the crucial reservoir-scale functions of relative permeability and capillary pressure and their dependencies on fluid and reservoir rock conditions. To conduct a conclusive study, in the absence of sufficient experimental data, a rigorous sensitivity analysis has been performed to quantify the impacts of uncertain fluid and rock properties on these upscaled functions. The parameters are varied around a base-case, which is obtained through matching to the existing experimental study. Moreover, cyclic hysteretic multiphase flow is also studied, which is a relevant aspect for cyclic hydrogen-brine energy storage projects. The present study applies pore-scale analysis to predict the flow of hydrogen in storage formations, and to quantify the sensitivity to the micro-scale characteristics of contact angle (i.e., wettability) and porous rock structure.
GHz optical pulse generation using traveling-wave electroabsorption modulator (2002)

Highly efficient traveling-wave electro-absorption modulators are fabricated with improved multi-quantum well design. The modulation efficiency is as high as 20 dB/V. 40 GHz optical pulses are generated with simple sinusoidal microwave drive. The shortest pulse generated is 4 ps. The experimental co-direction and counter-direction results presented in this works support the theoretical traveling-wave model of operation.

Ca2+-dependent regulation in neuronal gene expression (1997)

Ca2+ is an important signal-transduction molecule that plays a role in many intracellular signaling pathways. Recent advances have indicated that in neurons, Ca2+-controlled signaling mechanisms cooperate in order to discriminate amongst incoming cellular inputs. Ca2+-dependent transcriptional events can thereby be made selectively responsive to bursts of synaptic activity of specific intensity or duration.
5G Millimeter-Wave Dual-Band Beamforming Antenna and Wireless Link Tests (2023)

In this paper, a beamforming device is presented to work at two 5G millimeter-wave frequencies. It is a flat structure and is able to transmit and receive wireless signals through two 5G channels now that it takes the form of the substrate integrated waveguide (SIW) and a duplexing feed is connected to the radiating elements as one piece of equipment. The performance of this novel dual-band antenna is observed with n257 and n260 bands from standpoints of Sii as the return loss for impedance matching, Sij as channel distinction between ports i and j, and antenna gains. Directivity for the beamforming function based on the low impedance mismatch at the frequency bands is given as the simulated and measured data of the antenna under test (AUT). Also, wireless link is built by this antenna system with the capability of channel selection.
Use of probiotics as an alternative to formaldehyde fumigation in commercial broiler chicken hatch cabinets (2018)

Two experiments were conducted in a commercial broiler hatchery to evaluate the use of a spray probiotic formulation as an alternative method to control the bacterial bloom within a broiler hatch cabinet vs. formaldehyde fumigation. In Exp 1, 2 independent trials were conducted to compare hatchery sanitation between the current formaldehyde drip method vs. spray application of the probiotic. Hatchery sanitation was evaluated using the open-plate method at approximately 20% pip; 30% hatch; and 85% hatch for enumeration of total recovered non-selective aerobic bacteria (TAB); presumptive lactic acid bacteria (LAB); and total recovered Gram-negative bacteria (TGB). In Exp 2, 3 independent trials were conducted to evaluate the gastrointestinal (GIT) microbiota of neonatal chicks from hatch cabinets treated as in Exp 1. In Exp 1, in both trials, the application of the probiotic increased the number TAB and LAB present in the hatching environment (P < 0.05). Additionally, at 20% pip and 30% hatch, in both trials, there was no significant difference in TGB levels between the probiotic treatment and the formaldehyde treatment. In Exp. 2, chicks from probiotic treated hatch cabinets also showed a reduction of TGB in the GIT compared to the formaldehyde group (P < 0.05). In trial 3, the reduction in TGB persisted 24 h after hatch. The results of the present study suggest that spray application of a probiotic in commercial hatcheries can yield similar TGB levels when compared to formaldehyde early on in the hatch period. More importantly, it decreased the numbers of these bacteria within the GIT at hatch and 24 h after hatch.
Equilibrium and stability of tensegrity structures: A convex analysis approach (2012)

In this paper, tensegrity structures are modeled by introducing suitable energy convex functions. These allow to enforce both ideal and non-ideal constraints, gathering compatibility, equilibrium, and stability problems, as well as their duality relationships, in the same functional framework. Arguments of convex analysis allow to recover consistently a number of basic results, as well as to formulate new interpretations and analysis criterions.
Can Intensive Hemodialysis Prevent Loss of Functionality in the Elderly ESRD Patient? (2011)

Initiation of dialysis may be accompanied by decline in physical and cognitive function and independence, especially in the elderly ESRD patient. Here, we postulate the underlying factors, which may contribute to this observation in the elderly dialysis population, such as increased risk of dialysis-induced hypotension and associated cerebral and cardiac events, as well as malnutrition, infections, sleep abnormalities, and psychological complications of dialysis initiation. We describe an elderly dialysis patient who did well on nocturnal home hemodialysis (HD), and we hypothesize how intensive HD (i.e., nocturnal HD and/or short daily HD) may reduce the incidence of these dialysis complications and may therefore be considered as an option to attempt to preserve functional status and quality of life, especially early after the transition from predialysis to dialysis. Before general adoption of this strategy, further studies on the etiology of functional loss at the time of dialysis initiation, as well as on the potential advantageous effects of intensive HD in the elderly ESRD patient as compared with conventional HD, peritoneal dialysis and kidney transplantation, are required.
Therapeutic Effect of Novel Single-Stranded RNAi Agent Targeting Periostin in Eyes with Retinal Neovascularization (2017)

Retinal neovascularization (NV) due to retinal ischemia remains one of the principal causes of vision impairment in patients with ischemic retinal diseases. We recently reported that periostin (POSTN) may play a role in the development of preretinal fibrovascular membranes, but its role in retinal NV has not been determined. The purpose of this study was to examine the expression of POSTN in the ischemic retinas of a mouse model of oxygen-induced retinal NV. We also studied the function of POSTN on retinal NV using Postn KO mice and human retinal endothelial cells (HRECs) in culture. In addition, we used a novel RNAi agent, NK0144, which targets POSTN to determine its effect on the development of retinal NV. Our results showed that the expression of POSTN was increased in the vascular endothelial cells, pericytes, and M2 macrophages in ischemic retinas. POSTN promoted the ischemia-induced retinal NV by Akt phosphorylation through integrin αvβ3. NK0144 had a greater inhibitory effect than canonical double-stranded siRNA on preretinal pathological NV in vivo and in vitro. These findings suggest a causal relationship between POSTN and retinal NV, and indicate a potential therapeutic role of intravitreal injection of NK0144 for retinal neovascular diseases.
Optical frequency-interleaving full-duplex technique for fiber-optic transmission of millimeter-wave-band frequency-modulated continuous-wave downlink signal and 10-Gb/s on-off-keying uplink signal (2015)

An optical frequency-interleaving full-duplex technique for fiber-optic transmission of millimeter-wave-band frequency-modulated continuous-wave downlink signal and 10-Gb/s onoff-keying uplink signals is newly proposed. The proposed full-duplexing technique with a flexible wavelength channel selector is experimentally demonstrated.
Adaptive 5G Low-Latency Communication for Tactile InternEt Services (2018)

The tactile internet will enable a new range of capabilities to enable immersive remote operations and interactions with a physical world. Tactile internet use cases span over many fields, from remote operation of industrial applications in, e.g., hazardous environments, via remote-controlled driving in a fully automated intelligent transport system, to remote surgery where the unique expert skills can be delivered to different locations in the world. Fifth-generation (5G) communication will play a fundamental part in this tactile internet vision, as it will provide necessary capabilities for the demanding communication needs in terms of reliability and low latency, for operators or teleoperated systems that are connected wirelessly. This paper provides an overview of tactile internet services and haptic interactions and communication. The 5G functionality for ultrareliable and low-latency services is described in depth and it is shown how 5G new radio (NR) and the evolved long-term evolution (LTE) radio interface can achieve guaranteed low-latency wireless transmission. The costs for providing reliable and low-latency wireless transmission in terms of reduced spectral efficiency and coverage are discussed. The 5G system architecture with a software-based network design based on a distributed cloud platform is presented. It is shown how the 5G network is configured for tactile internet services via multidomain orchestration.
Hierarchically Self‐Assembled Host–Guest Network at the Solid–Liquid Interface for Single‐Molecule Manipulation (2008)

Now you see it, now you don't: A molecular monolayer polymorph of an oligopyridine forms a host–guest network with copper(II) phthalocyanine at the solid–liquid interface with controllable phthalocyanine occupation. The slow movement of the phthalocyanine guest molecules and the competition between oligopyridine and phthalocyanine guest molecules make it possible to manipulate individual guest molecules in analogy to “writing” and “erasing”.

Mining social interactionsin connection traces of a campus wi-fi network (2021)

Wi-Fi technologies have become one of the most popular means for Internet access. As a result, the use of mobile devices has become ubiquitous and instrumental for society. A device can be identified through its MAC address within an autonomous system. Although some devices attempt to anonymize MAC addresses via randomization, these techniques are not used once the device is associated to the network [7]. As a result, device identification poses a privacy problem in large-scale (e.g., campus-wide) Wi-Fi deployments [5]: if the mobile device can be located, the user who carries that device can also be located. In turn, location information leads to the possibility to extract private knowledge from Wi-Fi users, like social interactions, movement habits, and so forth.
Dropwise Condensation on Hydrophobic Cylinders (2016)

In this work, we studied the effect of the diameter of horizontal hydrophobic cylinders on droplet growth. We postulate that the concentration gradient created by natural convection around a horizontal circular cylinder is related to the droplet growth on the cylinder by condensation. We derive a simple scaling law of droplet growth and compare it with experimental results. The predicted negative exponent of drop diameter (d) as a function of cylinder diameter (D) at different time points is similar to the general trend of experimental data. Further, this effect of cylinder diameter on droplet growth is observed to be stronger than the supersaturation conditions created by different surface temperatures.
Chromium stress response effect on signal transduction and expression of signaling genes in rice (2013)

Hexavalent chromium [Cr(VI)] is a non-essential metal for normal plants and is toxic to plants at high concentrations. However, signaling pathways and molecular mechanisms of its action on cell function and gene expression remain elusive. In this study, we found that Cr(VI) induced endogenous reactive oxygen species (ROS) generation and Ca(2+) accumulation and activated NADPH oxidase and calcium-dependent protein kinase. We investigated global transcriptional changes in rice roots by microarray analysis. Gene expression profiling indicated activation of abscisic acid-, ethylene- and jasmonic acid-mediated signaling and inactivation of gibberellic acid-related pathways in Cr(VI) stress-treated rice roots. Genes encoding signaling components such as the protein kinases domain of unknown function 26, receptor-like cytoplasmic kinase, LRK10-like kinase type 2 and protein phosphatase 2C, as well as transcription factors WRKY and apetala2/ethylene response factor were predominant during Cr(VI) stress. Genes involved in vesicle trafficking were subjected to functional characterization. Pretreating rice roots with a vesicle trafficking inhibitor, brefeldin A, effectively reduced Cr(VI)-induced ROS production. Suppression of the vesicle trafficking gene, Exo70, by virus-induced gene silencing strategies revealed that vesicle trafficking is required for mediation of Cr(VI)-induced ROS production. Taken together, these findings shed light on the molecular mechanisms in signaling pathways and transcriptional regulation in response to Cr stress in plants.
Site-specific dexamethasone delivery for the prevention of neointimal thickening after vascular stent implantation (1994)

Sustained, local dexamethasone therapy has potent anti-inflammatory and anti-fibrotic effects but, with the dose and route of administration used in this study, does not reduce the intimal hyperplastic response to injury in this model.
Both somatostatin and insulin responses to glucose are impaired in the perfused pancreas of the spontaneously noninsulin‐dependent diabetic GK (Goto‐Kakizaki) rats (1993)

We have studied the responses of insulin and somatostatin to glucose and arginine in the perfused pancreas of GK rats, which spontaneously develop mild noninsulin-dependent diabetes without concomitant obesity. Our GK rats have been obtained after at least 42 generations of inbreeding of Wistar rats with initial selection for increased blood glucose levels during glucose tolerance tests. During perfusion with a high (16.7 mmol l-1) glucose concentration, normal responses of insulin and somatostatin were found in pancreata from non-diabetic control rats. In GK pancreata, however, these responses were virtually abolished. When the glucose concentration of the perfusion medium was switched from 16.7 to 3.3 mmol l-1 glucose, a transient increase- 'off-response' -in both insulin and somatostatin secretion was noted in GK but not in control pancreata. During the subsequent stimulation with arginine (20 mmol l-1), insulin and somatostatin responses were similar in pancreata from non-diabetic and GK rats. The pancreatic content of insulin did not differ between non-diabetic and GK rats, whereas the content of somatostatin was increased by 56% (P < 0.025) in GK glands. In conclusion, abnormalities assigned to pancreatic hormone secretion in the GK rat comprise not only markedly impaired insulin but also somatostatin response to glucose. Since there was no decrease in pancreatic content of these hormones in GK rats, the cause of glucose insensitivity of the hormone-producing cells is likely to reside in a defective stimulus-secretion coupling rather than decreased availability of the hormones.
Rod-Screw Constructs Composed of Dissimilar Metals Do Not Affect Complication Rates in Posterior Fusion Surgery Performed for Adult Spinal Deformity (2020)

We found no evidence that combining Ti screws with SS rods increases the risk for implant-related complications.
Optimisation d'un amortisseur d'une machine à courant continu : amélioration de la commutation (1993)

L'introduction d'un circuit amortisseur dans une machine à courant continu, alimentée par des courants ondulés, améliore notablement son fonctionnement. On présente dans cette étude, une méthode d'optimisation de cet enroulement supplémentaire. La f.e.m. de transformation générée par l'enroulement inducteur dans la section en commutation, les pertes par effet Joule dans l'amortisseur et l'inducteur, ainsi que le temps de réponse dynamique de la machine sont les critères de l'optimisation. Leurs variations en fonction de la section totale de l'enroulement amortisseur peuvent nous conduire à un amortisseur optimal.
Hairpin Structure of an RNA 28-mer, Which Contains a Sequence of the Enzyme Component of a Hammerhead Ribozyme System: Evidence for Tandem G: A Pairs That Are Not of Side-by-Side Type (1997)

An RNA 28-mer (Rz28) was obtained as a major product by in vitro transcription with T7 RNA polymerase of a promoter-template DNA, which contains a sequence for the enzyme component, RNA 24-mer (Rz24), of a mutant hammerhead ribozyme system. Sequence analysis and enzymatic probing study showed that Rz28 has 4 extra nucleotides at the 3'-terminus, the sequence of which is complementary to that of the 5'-terminal sequence of Rz24, and forms a stable hairpin structure. NMR studies using a 15N-guanine-labeled derivative suggested that Rz28 contains tandem G:A pairs that are not of the side-by-side type which is found in the crystal structure of hammerhead ribozyme complexes. Comparison of the HMQC spectra of 15N-guanine-labeled Rz28 and Rz24 suggested that Rz24 also contains the same type of tandem G:A pairs.
hnRNP A1 associates with telomere ends and stimulates telomerase activity (2006)

Telomerase is a ribonucleoprotein enzyme complex that reverse-transcribes an integral RNA template to add short DNA repeats to the 3'-ends of telomeres. G-quadruplex structure in a DNA substrate can block its extension by telomerase. We have found that hnRNP A1--which was previously implicated in telomere length regulation--binds to both single-stranded and structured human telomeric repeats, and in the latter case, it disrupts their higher-order structure. Using an in vitro telomerase assay, we observed that depletion of hnRNP A/B proteins from 293 human embryonic kidney cell extracts dramatically reduced telomerase activity, which was fully recovered upon addition of purified recombinant hnRNP A1. This finding suggests that hnRNP A1 functions as an auxiliary, if not essential, factor of telomerase holoenzyme. We further show, using chromatin immunoprecipitation, that hnRNP A1 associates with human telomeres in vivo. We propose that hnRNP A1 stimulates telomere elongation through unwinding of a G-quadruplex or G-G hairpin structure formed at each translocation step.

The Effect of Surface Active Elements on the Wetting Behavior of Iron by Molten Aluminum Alloy. (1995)

Measurementsof the contact angle of molten aluminum alloys (Al-Mg, Al-Cu and Al-Si al[oys) on solid iron substrate have been carried out aiming at developing a filler sheet for a welding between iron and aluminum. The wettability was estimated by a sessile drop method. The contact angle of molten aluminum drop was measuredat 773 and 893 K. Magnesium alloying decreases the contact angle of molten aluminum drop becavse an evaporation of magnesiumprevents a formation of a thin oxide layer at the surface of the molten drop. Since the vapor pressures of these elements at an experimental temperature are muchlower than that of magnesium,neither silicon nor copper alloying contributes to improving a wettability on a given experimental condition (T=893 K, P=1 .33 x I O-' Pa). A minute quantity of surface active elements such as bismuth, Iead and lithium was addedwith a view to decreasing the surface tension of molten aluminum ailoys..A 0.05 mass'/o addition of bismuth decreases the contact angle most effectively. An excessive addition, however, results in increasing the contact angle. The effect of bismuth addition is more significant at lower temperatures than at higher temperatures
