Capillary and van der Waals force between microparticles with different sizes in humid air (2015)

It is well known that surface effect forces, such as van der Waals force and capillary force, are the major contributions to adhesion when microsized particles are in contact in humid environment. But it is very complex to calculate the adhesion force between two smooth unequal particles. In conventional approaches, the effective particle radius approximation and the constant half-filling angle assumptions are often used for computing the van der Waals forces between two microparticles. However, the approximation and the assumption are actually difficult to accurately model the forces between unequal particle sizes when the surfaces are with different properties. In this paper, we present a theoretical study of the van der Waals force and capillary force between two microparticles with different radii and the surface properties linked by a liquid bridge. The proposed model provides the adhesion force predictions in good agreement with the previous formula and existing experiment data. Considering the solid particles are partially wetted by the liquid bridge, the van der Waals force is calculated by divided the particle surface into a wetted part and a dry portion in our stimulation. Since the wetted surface portion of the particle is determined by the half-filling angle, the relationship between two half-filling angles of the unequal size particles is developed from the geometrical consideration, which is relate to the size ratio of the particles, the contact angle, and the separation distance. Then, the van der Waals force is determined using the surface element integration. Moreover, the influences of humidity, particles size, contact angle, and separation distance toward the adhesion forces are discussed using the proposed method. Simulations indicate that a higher relative humidity leads to bigger liquid bridges, suggesting a higher capillary force, but at the same time, the van der Waals force decreases due to the decrease in surfaces energy. As for the influence of contact angle, results show that a higher contact angle, that is, a more hydrophobic surface, reduces the capillary force but increases the van der Waals force (absolute value). The simulations also show that the both the capillary force and the van der Waals force (absolute value) increase as the particle size increases. When the particles are separated from each other, the capillary force and van der Waals force decreases gradually. These results are helpful to understand and utilize the adhesion interaction between particles with unequal sizes at the ambient condition.
Plasmonic Color Filters Integrated on a Photodiode Array (2017)

SUMMARY Arrayed plasmonic color filters integrated on Si photodiodes with 21 elements were experimentally demonstrated. The plasmonic color filters consisted of nanodot subwavelength periodic structures. Optical characteristics of the color filters were measured and compared with calculated results. In order to obtain spectrum of an incident light from the signal of photodiodes, spectrum reconstruction using Tikhonov regularization was adapted. In the spectral sensitivity of each photodiode, the peak wavelength was adjusted between 400 and 850 nm in wavelength by the period of nanodot structure on each photodiode. The measured peak wavelengths roughly agreed with calculated values with errors less than 30 nm in wavelength. Spectral characteristics of a monochromatic light were measured by fabricated device and spectrum reconstruction was carried out. The position of the center wavelength could be successfully detected.
Estrogen rapidly modulates mustard oil-induced visceral hypersensitivity in conscious female rats: a role of CREB phosphorylation in spinal dorsal horn neurons (2006)

This study investigated the effect of sex hormones on mustard oil (MO)-induced visceral hypersensitivity in female rats and analyzed possible involved signaling pathways. Female rats, either intact or ovariectomized (OVX), were prepared for abdominal muscle electromyography in response to colorectal distension after intracolonic instillation of MO. The effect of MO intracolonic sensitization was evaluated in intact rats, OVX rats, and OVX rats pretreated with a single injection of 17β-estradiol (E), progesterone (P), E+P, or vehicle. cAMP-responsive element-binding protein (CREB) and phosphorylated CREB (pCREB) were detected in the superficial dorsal horn of L 6 and S 1 in MO or mineral oil-treated OVX rats with/without colorectal distension and estrogen replacement. The distal colorectum was removed for histological evaluation of inflammatory severity in MO-treated intact or OVX rats. The MO-treated rats had significantly higher visceromotor reflex than controls (enhanced visceral hypersensitivity), whereas OVX eliminated this hypersensitivity. After a single injection of E or E+P, the rats rapidly restored MO-induced visceral hypersensitivity within 2 h. Estrogen also rapidly induced a dose-dependent increase in pCREB expression in the superficial dorsal horn neurons in MO-treated, but not mineral oil-treated, OVX rats. The present study suggests that estrogen can rapidly modulate visceral hypersensitivity induced by MO intracolonic instillation in conscious female rats, which may involve spinal activation of the cAMP response element-mediated gene induction pathway.

Calcium level‐responsive invitro zinc release from zinc containing tricalcium phosphate (ZnTCP) (2000)

The in vitro Zn release from tricalcium phosphate containing Zn (ZnTCP; 0.63, 6.17, and 12.05 Zn w/w%) was investigated. The rates of release from ZnTCP powders were measured in 25 mL of simulated body fluid (SBF) containing 10 mg/100mL Ca (SBF/H), 5 mg/100mL Ca (SBF/L), or no Ca (SBF/−) at pH 7.25, 37.0 ± 0.1°C. The release from 6 and 12% ZnTCP was initially very fast. The rate of release from ZnTCP decreased as the concentration of Ca in the dissolution media increased, but increased as concentration of Zn in TCP increased. The dissolution kinetics of ZnTCP followed the Hixon-Crowell equation at the initial stage of dissolution, and the initial dissolution rate constant (IDR) was calculated by the least-squares method. The effect of Ca concentration on percent IDR of ZnTCP suggested that Zn release from 0.6% ZnTCP was significantly high compared to that from 6 or 12% ZnTCP. The relationship between the amount of Ca precipitated and Zn release of various ZnTCP samples suggested that the release from 0.6% ZnTCP was significantly different compared to that from 6 and 12% ZnTCP, consistent with the data for percent Zn IDR. X-ray diffraction data suggested that 0.6% ZnTCP contained 5% hydroxyapatite, a low solubility material, which acted as seed crystal during the dissolution test. © 2000 John Wiley & Sons, Inc.

Beneficial and deleterious effects of cannabinoids in the brain: the case of ultra-low dose THC (2019)

This article reviews the neurocognitive advantages and drawbacks of cannabinoid substances, and discusses the possible physiological mechanisms that underlie their dual activity. The article further reviews the neurocognitive effects of ultra-low doses of ∆9-tetrahydrocannabinol (THC; 3-4 orders of magnitude lower than the conventional doses) in mice, and proposes such low doses of THC as a possible remedy for various brain injuries and for the treatment of age-related cognitive decline.
Nanoclusters in Nanocages:  Platinum Clusters and Platinum Complexes in Zeolite LTL Probed by 129Xe NMR Spectroscopy (2002)

Platinum nanoclusters and mononuclear platinum complexes in zeolite KLTL were characterized by 129Xe NMR spectroscopy at temperatures from 100 to 296 K; the chemical shift increased with decreasing temperature, consistent with xenon's increasingly strong interactions with the platinum. The room-temperature chemical shift of xenon characterizing the zeolite containing the platinum clusters was 148.7 ppm, but that of the zeolite containing the platinum complexes was only 98.3 ppm, slightly greater than the value representing the bare zeolite, 95.4 ppm. These data, combined with literature data characterizing similar samples, indicate that the 129Xe chemical shift increases with the size of the metal species in the zeolite, up to the point at which entry of the Xe atom into the space containing the metal is constrained by the geometry of the metal species and the zeolite cage; in the limiting case, the chemical shift is substantially reduced because a Xe atom interacts with an encaged nanocluster only through a cage window.

At our center, treatments given for nasopharyngeal carcinoma from 1992 to 2002 had acceptable toxicity rates. Further follow-up of patients treated with modern radiotherapy planning methods and chemotherapy regimens is needed to compare our institutional results with other published outcomes with more validity.
Resolution of late-onset heart and liver failures after reversion of jejuno-ileal bypass: a case report (2018)

Objectives: Jejuno-ileal bypass (JIB) was a kind of bariatric surgery performed from 1960s to 1980s, able to induce sustainable weight loss by creating a surgical short bowel syndrome.Materials and methods: We report a case of an octogenarian woman who underwent in the early eighties this kind of surgery with consequent 40 kg weight loss. After 27 years, she first developed a reversible metabolic cardiomyopathy that began with signs and symptoms of heart failure. Thereafter, she was diagnosed with severe intractable liver insufficiency.Results: Despite her old age, the patient underwent reversal of JIB with consequent early improvement of hepatic function.Conclusions: This case demonstrate that in case of long-term and life-threatening complications, it is possible to successfully reverse JIB surgery after upto 30 years. The hypothesis on pathophysiology of heart and liver insufficiency are discussed.
Buscar el levante por el poniente: in search of fairness through interactivity in massively multiplayer online games (2006)

Ensuring fairness among players engaged in online games is a challenging task. Yet, it is a fundamental requirement that can make the difference between having customers that persist or desist in using this kind of application. Answering to this demand, we present here an event delivery mechanism among mirrored game servers able to effectively uplift the fairness degree during game sessions through the heterogenesis of ends in targeting interactivity. We also provide extensive results that sustain our claim.
Adjusting the Local Arrangement of π-Stacked Oligothiophenes through Hydrogen Bonds: A Viable Route to Promote Charge Transfer (2014)

We show that substituting quaterthiophene cores with strong H-bond aggregators, such as urea groups, provides an efficient way to adjust the mutual in-plane displacements of the semiconducting units and promote charge transfer. Our 2-D structure-property mapping reveals that the insertion of substituents induces up to 2.0 Å longitudinal and transversal displacements between the π-conjugated moieties. Some of these relative displacements lead to improved cofacial orbital overlaps that are otherwise inaccessible due to Pauli repulsion. Our results also emphasize that the fine-tuning of in-plane displacements is more effective than achieving "tighter" packing to promote charge-transfer properties.
Titanium Hydroxide as a New Inorganic Fluoride Ion Exchanger. (2002)

Although TiO2 exhibits a small fluoride ion exchange capacity, it was found that titanium hydroxide, Ti(OH)4, can exchange fluoride ion with large saturation capacity of 1.60m·mol/g. Although the H2PO4- interferes with the F- exchange, the amount of F- exchange of Ti(OH)4 was hardly changed by the coexistence of Cl-, NO3-, and SO42-. The capacity for F- exchange was almost unchanged over 4 times repetition of ion-exchange and desorption and furthermore, the elution of Ti was negligibly small. Consequently, Ti(OH)4 is expected to be a new inorganic F- exchanger for the removal of fluoride ion from wastewater.
CuCl-HCl Electrolyzer for Hydrogen Production via Cu-Cl Thermochemical Cycle (2009)

The Cu-Cl thermochemical cycle is among the most attractive technologies proposed for hydrogen production due to moderate temperature requirements and high efficiency. In the present study, one of the main steps of the cycle - H2 gas production via CuCl-HCl electrolysis - was investigated using a newly designed electrolyzer system. The electrolysis reaction was performed with the applied voltage from 0.35 to 0.9 V. The current efficiency of the electrolysis system was evaluated based on the observed rate of hydrogen production. The effects of temperature and reagent flow rate on the electrolysis performance were studied. Several types of anion-exchange and cation-exchange membranes were tested in the electrolyzer, and their performance was compared with respect to process efficiency and tolerance to copper crossover.
Polarimetric backscattering signatures from thin saline ice under controlled laboratory conditions (2002)

The authors carried out an experiment to measure polarimetric backscattering signatures from thin ice at the US Army Cold Regions Research and Engineering Laboratory. The purpose of the experiment is to provide data for understanding scattering mechanisms in sea ice to develop models relating polarimetric signatures to physical, morphological, and electromagnetic properties of sea ice. Saline ice was grown in an indoor pit with the air temperature kept about -20/spl deg/C to simulate the cold arctic condition. During the ice growth, a C-band polarimetric scatterometer was used to acquire backscattering matrices as functions of incident angles for ice thicknesses up to 12 cm. Moreover, the authors investigated polarimetric signatures of thin ice under various modified conditions including frost flower, ice warming, surface flooding, and slush layer. Ice characterization parameters and samples were collected to relate ice properties to the microwave polarimetric signatures.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Ardeparin (low-molecular-weight heparin) vs graduated compression stockings for the prevention of venous thromboembolism. A randomized trial in patients undergoing knee surgery. (1996)

Ardeparin administered postoperatively twice daily is effective and safe for the prevention of venous thrombosis in patients undergoing major knee surgery. Whereas graduated compression stockings have been shown to be effective prophylactic agents in general surgery and neurosurgery, they have little effect in knee surgery.
Mechanochromic luminescence properties of fluoro-substituted pinene-containing cyclometalated platinum(ii) complexes with multiple triplet excited states (2021)

The structure-mechanochromism relationship is explored with respect to packing patterns and corresponding intermolecular interactions that are affected by the number and location of -F. The distinct and reversible mechanochormic luminescence (Δλem up to ca. 90 nm) of yellow solids (-)-1-Yg, (-)-2-Yg, and (-)-3-Yg was displayed with a simultaneous crystal-to-amorphous transformation. The change of multiple triplet excited states accounted for the mechanochormic luminescence, and a switch from the 3π,π* monomer to the excimer/3MMLCT occurred in the grinding process. The mechanical force led to perturbation in the molecular packing, and aggregates with effective PtPt and π-π interactions were formed in the amorphous phase, leading to the variation of excited states. The mechanochromic luminescence could be reverted by dropping in CH2Cl2 and could be cycled multiple times without perceivable performance degradation. This work gives a reference for designing mechanochromic luminescent materials toward multicolor and multicomponent responses.
Targeting the epichaperome as an effective precision medicine approach in a novel PML-SYK fusion acute myeloid leukemia (2021)

The epichaperome is a new cancer target composed of hyperconnected networks of chaperome members that facilitate cell survival. Cancers with an altered chaperone configuration may be susceptible to epichaperome inhibitors. We developed a flow cytometry-based assay for evaluation and monitoring of epichaperome abundance at the single cell level, with the goal of prospectively identifying patients likely to respond to epichaperome inhibitors, to measure target engagement, and dependency during treatment. As proof of principle, we describe a patient with an unclassified myeloproliferative neoplasm harboring a novel PML-SYK fusion, who progressed to acute myeloid leukemia despite chemotherapy and allogeneic stem cell transplant. The leukemia was identified as having high epichaperome abundance. We obtained compassionate access to an investigational epichaperome inhibitor, PU-H71. After 16 doses, the patient achieved durable complete remission. These encouraging results suggest that further investigation of epichaperome inhibitors in patients with abundant baseline epichaperome levels is warranted.
Fracturing Perspectives in Deep HPHT Well: Comprehensive Analysis using High-Frequency Pressure Monitoring, Flowback-Rebound and Step-Rate Tests (2019)

Abstract Analysis of production perspectives for very deep wells (below 20,000 ft true vertical depth) is closely related to understanding of the hydraulic fracturing perspectives because at these depths, the overburden stresses and long geological history of the target formations usually result in low permeability. Costs of hydraulic fracturing operations in this type of well is significantly higher than in shallower conditions; however, the risk of nonprofitable outcome is significant. A workflow, including several key methods, is suggested to mitigate the operational and financial risks of potential hydraulic fracturing operations in very deep environments. These techniques employ cost-effective yet technically strong tools for determination of required reservoir parameters and well information, including fracture closure pressure, reservoir pressure, formation transmissibility, and well tubulars integrity. Suggested methods avoid well intervention and associated rig and services costs. The workflow was applied in a very deep and hot well with target intervals below 21,000 ft and helped in estimating the fracturing perspectives in an efficient manner.
Segregating YKU80 and TLC1 Alleles Underlying Natural Variation in Telomere Properties in Wild Yeast (2009)

In yeast, as in humans, telomere length varies among individuals and is controlled by multiple loci. In a quest to define the extent of variation in telomere length, we screened 112 wild-type Saccharomyces sensu stricto isolates. We found extensive telomere length variation in S. paradoxus isolates. This phenotype correlated with their geographic origin: European strains were observed to have extremely short telomeres (<150 bp), whereas American isolates had telomeres approximately three times as long (>400 bp). Insertions of a URA3 gene near telomeres allowed accurate analysis of individual telomere lengths and telomere position effect (TPE). Crossing the American and European strains resulted in F1 spores with a continuum of telomere lengths consistent with what would be predicted if many quantitative trait loci (QTLs) were involved in length maintenance. Variation in TPE is similarly quantitative but only weakly correlated with telomere length. Genotyping F1 segregants indicated several QTLs associated with telomere length and silencing variation. These QTLs include likely candidate genes but also map to regions where there are no known genes involved in telomeric properties. We detected transgressive segregation for both phenotypes. We validated by reciprocal hemizygosity that YKU80 and TLC1 are telomere-length QTLs in the two S. paradoxus subpopulations. Furthermore, we propose that sequence divergence within the Ku heterodimer generates negative epistasis within one of the allelic combinations (American-YKU70 and European-YKU80) resulting in very short telomeres.
Two-stage space-time receiver for UMTS frequency division duplex (2005)

We examine a space-time multiuser receiver with two parallel interference cancellation (PIC) stages for the uplink in the UMTS-FDD mode. The structure has a performance which is better than the one of the maximum-ratio combiner (MRC) and can reach the single-user performance under the assumption of perfect channel knowledge. Even with channel estimation the proposed receiver achieves a very good performance while maintaining low complexity.
Ultrasonic transient bounded-beam propagation in a solid cylinder waveguide embedded in a solid medium (2007)

A semianalytical solution alternative and complementary to modal technique is presented to predict and interpret the ultrasonic pulsed-bounded-beam propagation in a solid cylinder embedded in a solid matrix. The spectral response to an inside axisymmetric velocity source of longitudinal and transversal cylindrical waves is derived from Debye series expansion of the embedded cylinder generalized cylindrical reflection/transmission coefficients. So, the transient guided wave response, synthesized by inverse double Fourier-Bessel transform, is expressed as a combination of the infinite medium contribution, longitudinal, transversal, and coupled longitudinal and transversal waveguide sidewall interactions. Simulated (f, 1/lambdaz) diagrams show the influence of the number of waveguide sidewall interactions to progressively recover dispersion curves. Besides, they show the embedding material filters specific signal portions by concentrating the propagating signal in regions where phase velocity is closer to phase velocity in steel. Then, simulated time waveforms using broadband high-frequency excitation show that signal leading portions exhibit a similar periodical pattern, for both free and embedded waveguides. Debye series-based interpretation shows that double longitudinal/transversal and transversal/longitudinal conversions govern the time waveform leading portion as well as the radiation attenuation in the surrounding cement grout. Finally, a methodology is deduced to minimize the radiation attenuation for the long-range inspection of embedded cylinders.
