Lithographic performance of a dry-etch stable methacrylate resist at 193 nm (1998)

High resolution performance down to the 0.13 micrometers level is demonstrated in a methacrylate resist with pendent polycyclic side groups. The best performance is achieved with a bottom coat although interactions with the resist were still observed which led to the presence of scum in fine lines and to a large dose change relative to silicon. The demonstrated dry etch rate of the resist was found to be about 10% higher than APEX-E; predictions based on the ring parameter would have led us to expect a more favorable etch rate. The observed discrepancy has led us to speculate on possible exposure of the resist by the plasma environment and loss of the etch resistance polycyclic unit through evaporation.
Investigations of Electrical Properties in Silica/Indium Tin Oxide Two‐Layer Film for Effective Electromagnetic Shielding (2004)

The effect of zinc ions added to silica film on the electrical and structural properties of a silica/indium tin oxide two‐layer film which had been prepared by solution coating for electromagnetic shielding of displays was studied. The volume resistivity of the undoped silica/indium tin oxide film was more than 3 times as high as that of the zinc‐doped silica/indium tin oxide film. The addition of divalent cations, zinc ions, to the overcoated layer led volume resistivity of the two‐layer film to decrease significantly and also caused a long‐term increase in stability. The decrease in volume resistivity was due to the addition of zinc ions that changed the interface ionization and helped to enhance the electrical conductivity in the two‐layer film.

Obesity Is a Positive Modulator of IL-6R and IL-6 Expression in the Subcutaneous Adipose Tissue: Significance for Metabolic Inflammation (2015)

The role of IL-6R/IL-6 axis in metabolic inflammation remains controversial. We determined the changes in adipose tissue expression of IL-6R and IL-6 in obese, overweight, and lean non-diabetic individuals. Subcutaneous adipose tissue biopsies were collected from 33 obese, 22 overweight, and 10 lean individuals and the expression of IL-6R, IL-6, TNF-α, MCP-1, IP-10, CD11b, CD163, and CD68 was detected by immunohistochemistry; results were also confirmed by real-time RT-PCR and confocal microscopy. The data were compared using unpaired t-test and the dependence between two variables was assessed by Pearson's correlation test. Obese individuals showed higher IL-6R expression (103.8±4.807) in the adipose tissue as compared with lean/overweight (68.06±4.179) subjects (P<0.0001). The elevated IL-6R expression correlated positively with body mass index (BMI) (r=0.80 P<0.0001) and percent body fat (r=0.69 P=0.003). The increased IL-6R expression in obesity was also confirmed by RT-PCR (Obese: 3.921±0.712 fold; Lean/Overweight: 2.191±0.445 fold; P=0.0453) and confocal microscopy. IL-6 expression was also enhanced in obese adipose tissue (127.0±15.91) as compared with lean/overweight (86.69±5.25) individuals (P=0.03) which correlated positively with BMI (r=0.58 P=0.008). IL-6 mRNA expression was concordantly higher in obese (16.60±2.214 fold) versus lean/overweight (9.376±1.656 fold) individuals (P=0.0108). These changes in the IL-6R/IL-6 expression correlated positively with the adipose tissue expression of CD11b (IL-6R r=0.44 P=0.063; IL-6 r=0.77 P<0.0001), CD163 (IL-6R r=0.45 P=0.045; IL-6 r=0.55 P=0.013), TNF-α (IL-6R r=0.73 P=0.0003; IL-6 r=0.60 P=0.008), MCP-1 (IL-6R r=0.61 P=0.005; IL-6 r=0.63 P=0.004) and IP-10 (IL-6R r=0.41 P=0.08; IL-6 r=0.50 P=0.026). It was, therefore, concluded that obesity was a positive modulator of IL-6R and IL-6 expression in the adipose tissue which might be a contributory mechanism to induce metabolic inflammation.
The Arabidopsis SUPERMAN Gene Mediates Asymmetric Growth of the Outer Integument of Ovules (1995)

Immobilization of Human Red Blood Cells (1980)

Human red blood cells were immobilized in an alginate network which was cross-linked with Ca2+ ions. The immobilized cells were stored for longer than 5 weeks at 4 degrees C in an isotonic buffered NaCl solution containing glucose, inosine, adenine, and guanosine for energy supply. The immobilized cells were released from the alginate network by dissolving the matrix with citrate. Both the immobilized and released cells retain their biconcave shape over the storage period. Measurements of the released cell population in a hydrodynamically focussing Coulter Counter demonstrated that the mean size of the size distribution, the breakdown voltage, and the internal conductivity have not changed in contrast to control measurements on red blood cells stored conventionally in suspension indicating that immobilization preserves cellular functions.
Redox-active cyclopentadienyl Ni complexes with quinoid N-heterocyclic carbene ligands for the electrocatalytic hydrogen release from chemical fuels (2013)

We now report the electrocatalytic dehydrogenation of tetrahydroquinaldine by an electron-rich CpNi N-heterocyclic carbene (NHC) with quinoid ligand motifs and explore the effects of quinone additives on CpNi compounds without quinoid NHC ligands. Our CpNi(NHC) catalyst exhibits dehydrogenative electrocatalytic activity and demonstrates that a molecular catalyst precursor can be viable in the electrode-driven (H+ + e−) release step of “virtual hydrogen storage”.
Acoustic Emission Applied Outside of the Laboratory (1972)

The paper presents a cross section of beneficial applications which illustrate the wide variety of present day uses of acoustic emission surveillance. These uses range from detection of flaws in pressure vessels during hydrostatic testing to inspection of building floors for detecting weak points, detection of impending failure in localized segments of rock structure in mining, and process control in metal forming work. While these examples are not all inclusive, they do show that acoustic emission is not just a laboratory novelty and that beneficial use of the phenomenon is beginning to be realized.
Handling the Backhaul Link Failure for IEEE 802.16m Femto ABSs (2011)

A Fem to Advanced Base Station (ABS) is a low-power base station and used to extend Worldwide Interoperability for Microwave Access (WiMAX) coverage to the indoor areas. The Fem to ABS utilizes broadband connection (e.g., cable or DSL) as its backhaul link to connect to the mobile operator's network and Internet. However, the broadband connection is less reliable than the dedicate line. In other words, the Fem to ABS has more backhaul failure probability than the Macro ABS which uses the dedicate line. In order to reduce the impact of backhaul link failure, this paper proposes two mechanisms to handle the backhaul link failure based on different interfaces defined in IEEE 802.16m. This paper then compares these mechanisms in terms of the additional interface requirement, the notification method, the authentication/key exchange and the re-registration requirement. This paper also develops an analytic model to study the disruption time and packet loss of the proposed mechanisms.

TRINI: an adaptive load balancing strategy based on garbage collection for clustered Java systems (2016)

Summary Nowadays, clustered environments are commonly used in high‐performance computing and enterprise‐level applications to achieve faster response time and higher throughput than single machine environments. Nevertheless, how to effectively manage the workloads in these clusters has become a new challenge. As a load balancer is typically used to distribute the workload among the cluster's nodes, multiple research efforts have concentrated on enhancing the capabilities of load balancers. Our previous work presented a novel adaptive load balancing strategy (TRINI) that improves the performance of a clustered Java system by avoiding the performance impacts of major garbage collection, which is an important cause of performance degradation in Java. The aim of this paper is to strengthen the validation of TRINI by extending its experimental evaluation in terms of generality, scalability and reliability. Our results have shown that TRINI can achieve significant performance improvements, as well as a consistent behaviour, when it is applied to a set of commonly used load balancing algorithms, demonstrating its generality. TRINI also proved to be scalable across different cluster sizes, as its performance improvements did not noticeably degrade when increasing the cluster size. Finally, TRINI exhibited reliable behaviour over extended time periods, introducing only a small overhead to the cluster in such conditions. These results offer practitioners a valuable reference regarding the benefits that a load balancing strategy, based on garbage collection, can bring to a clustered Java system.

Melatonin induces pro-apoptotic signaling pathway in human pancreatic carcinoma cells (PANC-1) (2010)

Pancreatic cancer is a highly lethal disease with a poor prognosis for long-term survival rate at all stages of invasiveness. It responds poorly to radio- and chemotherapy because the tumor cells are resistant to apoptosis. Melatonin has been reported to inhibit pancreatic cancer growth in experimental studies in animals but the effect of melatonin on cultured human pancreatic carcinoma cells has not been tested. Moreover, we have recently shown that melatonin stimulates production of two major anti-apoptotic heat shock proteins, HSP27 and HSP 90, in pancreatic carcinoma cells. This study investigated the changes in intrinsic pathway of apoptosis at the mitochondrial level and cascade of caspases in human pancreatic carcinoma cells (PANC-1) cells subjected to melatonin and/or luzindole. Melatonin (10⁻⁸ -10⁻¹² m), the nonselective melatonin receptor antagonist, luzindole (10⁻⁸ -10⁻¹² m) or a combination of both agents were added to PANC-1 cell cultures. Cells were harvested, and the cytoplasmic proteins were isolated after 24 and 48 hr of incubation and analyzed employing co-immunoprecipitation and western blot. Administration of melatonin to the PANC-1 cells resulted in the stimulation of Bcl-2/Bax and caspase-9 proteins levels. The strongest signal of these pro-apoptotic factors was observed at the low concentration (10⁻¹² m) of melatonin. Pretreatment with luzindole alone and prior to the addition of melatonin reversed the stimulatory effect of this indoloamine on Bcl-2/Bax and caspase-9 proteins expression in PANC-1 cells. This is the first study to demonstrate a pro-apoptotic effect of low (physiological) concentration of melatonin on the pancreatic carcinoma cells. In conclusion, melatonin induced pro-apoptotic pathways in human pancreatic carcinoma, probably by interaction with the Mel-1 A/B receptors.
Understanding Decision-Making in Data Warehousing and Related Decision Support Systems (2002)

Many businesses have made or are making significant investments in data warehouses that reportedly support a myriad of decision support systems (DSS). Due to the newness of data warehousing and related DSS (DW-DSS), the nature of the decision support provided to DW-DSS users and the related impact on decision performance have not been investigated in an applied setting. An explanatory case study was undertaken at a financial services organization that implemented a particular type of DW-DSS, a Customer Relationship Management (CRM) system. The DSS-decision performance model has provided some theoretical guidance for this exploration. The case study results show that the decision-making support provided by these systems is limited and that an extended version of the DSS-decision performance model may better describe the factors that influence individual decision-making performance.

Rational Design of Mechano‐Responsive Optical Materials by Fine Tuning the Evolution of Strain‐Dependent Wrinkling Patterns (2013)

Rational design strategies for mechano‐responsive optical material systems are created by introducing a simple experimental system that can continuously vary the state of bi‐axial stress to induce various wrinkling patterns, including stripes, labyrinths, herringbones, and rarely observed checkerboards, that can dynamically tune the optical properties. In particular, a switching of two orthogonally oriented stripe wrinkle patterns from oxidized polydimethylsiloxane around the critical strain value is reported, as well as the coexistence of these wrinkles forming elusive checkerboard patterns, which are predicted only in previous simulations. These strain‐induced wrinkle patterns give rise to dynamic changes in optical transmittance and diffraction patterns. A theoretical description of the observed pattern formation is presented which accounts for the residual stress in the membrane and allows for the fine‐tuning of the window of switching of the orthogonal wrinkles. Applications of wrinkle‐induced changes in optical properties are demonstrated, including a mechanically responsive instantaneous privacy screen and a transparent sheet that reversibly reveals a message or graphic and dynamically switches the transmittance when stretched and released.
Use of a gonadotropin-releasing hormone agonist analogue for treatment of cyclic auditory dysfunction. (1989)

A patient with cyclic luteal phase high-frequency hearing loss is described. This was documented by pre- and post-menstrual audiograms indicating a 40-dB hearing loss in the luteal phase. This had been long-standing and was resistant to oral contraceptive therapy. A gonadotropin-releasing hormone agonist (nafarelin) was used to inhibit ovarian function and was successful in preventing loss of hearing for the 6-month treatment period.
IMMUNE RESPONSES OF SOME INSECTS TO SOME BACTERIAL ANTIGENS (1959)

Pseudomonas aeruginosa (Schroeter) Migula antigen remained in the blood of larvae of the wax moth, Galleria mellonella (L.), during the resistant period of the insect. Bacterial antigen present in the immune blood produces agglutinating titers in rabbits about 10 times as great as those produced by an approximately equal volume of standard P. aeruginosa vaccine. Attempts to demonstrate the mechanism that enhances the antigen showed that the active portion was contained in the serum, that the action occurred within several hours in vivo and only reached the same level after 3 days in vitro mixture, and that the action was probably not caused by lysis of the bacterial cells and the consequent liberation of more antigen in the blood. Electrophoretic studies on the blood mixture indicated that the altered or enhanced antigen may be bound to a blood fraction, the exact nature of which was not determined. The larvae were actively or passively immunized against lethal doses of P. aeruginosa within 20 to 24 hours. Concentration of vaccine had little effect upon the degree of immunity conferred upon the larvae. The immunity lasted about three days and was more specific than nonspecific. The larvae were not actively protected against P. aeruginosa by introduction of albuminous foreign material into the body cavity. True antibodies were not detectable in the immune blood though the bactericidal action of immune blood was at least twice as great as that of normal blood. Preliminary investigations on immune responses of other lepidopterous insects to P. aeruginosa antigen and of the wax moth to antigens of some other Gram-negative bacteria indicated similar results.
Real-time immunoassays using fiber optic long-period grating sensors (1996)

Photoinduced long-period gratings (LPG) in optical fibers offer a completely new approach to the fabrication of highly sensitive evanescent wave biosensors. In contrast to other types of evanescent wave sensors where a surface plasmon must be carefully constructed from a waveguide substrate that must be polished and deposited with a thin metallic film of precise thickness via a sputtering process, the proposed technique simply relies on the formation of gratings within a communication grade germanium-doped optical fiber. Using an amplitude mask that is optimized for operation at 244 nm, an incoming collimated UV beam forms a spatially periodic optical intensity pattern along the axis of the fiber. Given sufficient exposure time on the order of seconds, a refractive index grating is induced within the core of the fiber. In this method, the LPG is used to detect and monitor in real-time the interaction of a specific antigen to the immobilized antibody on the silica fiber. When the density of the bound protein changes (i.e., when the antigen binds to the antibody), the associated refractive index of the bound film will also change. If a broadband light source is injected into the optical fiber, the output spectrum of the LPG sensor will shift in response to the refractive index changes.
Glutamate racemase as a target for drug discovery (2008)

The bacterial cell wall is a highly cross-linked polymeric structure consisting of repeating peptidoglycan units, each of which contains a novel pentapeptide substitution which is cross-linked through transpeptidation. The incorporation of D-glutamate as the second residue is strictly conserved across the bacterial kingdom. Glutamate racemase, a member of the cofactor-independent, two-thiol-based family of amino acid racemases, has been implicated in the production and maintenance of sufficient d-glutamate pool levels required for growth. The subject of over four decades of research, it is now evident that the enzyme is conserved and essential for growth across the bacterial kingdom and has a conserved overall topology and active site architecture; however, several different mechanisms of regulation have been observed. These traits have recently been targeted in the discovery of both narrow and broad spectrum inhibitors. This review outlines the biological history of this enzyme, the recent biochemical and structural characterization of isozymes from a wide range of species and developments in the identification of inhibitors that target the enzyme as possible therapeutic agents.
