On Compactly Supported Spline Wavelets and a Duality Principle (1992)

Let $\cdots \subset {V_{ - 1}} \subset {V_0} \subset {V_1} \subset \cdots$ be a multiresolution analysis of ${L^2}$ generated by the $m$th order $B$-spline ${N_m}(x)$. In this paper, we exhibit a compactly supported basic wavelet ${\psi _m}(x)$ that generates the corresponding orthogonal complementary wavelet subspaces $\cdots ,{W_{ - 1}},{W_0},{W_1}, \ldots$. Consequently, the two finite sequences that describe the two-scale relations of ${N_m}(x)$ and ${\psi _m}(x)$ in terms of ${N_m}(2x - j),j \in \mathbb {Z}$, yield an efficient reconstruction algorithm. To give an efficient wavelet decomposition algorithm based on these two finite sequences, we derive a duality principle, which also happens to yield the dual bases $\{ {\tilde N_m}(x - j)\}$ and $\{ {\tilde \psi _m}(x - j)\}$, relative to $\{ {N_m}(x - j)\}$ and $\{ {\psi _m}(x - j)\}$, respectively.
Nanofabrication in cellular engineering (1998)

Biological cells are strongly influenced by the topography of the surface on which they live, both in cell culture and in an animal. They are guided along micron sized grooves and change their shape becoming more elongated. On the other hand, cells do not adhere to surfaces that are covered in small nanometrically sized pillars. These effects can be used for cellular engineering purposes to determine the behavior of cells and in particular to make prostheses for medical purposes. The differences in micro and nanofabrication techniques necessary to adapt normal semiconductor technology for these purposes are discussed. Patterning of plastics using mechanical methods (embossing and molding) is shown to have excellent resolution, can be used on biodegradable material and a large enough area of patterned material can be produced at a reasonable cost. An application of this technology to the repair of broken tendons is discussed in some detail. It is shown that a biodegradable membrane patterned by embossing with a fused silica master can be used to effect tendon repair. Not only does the tendon reheal, but the synovial channel that should surround the tendon and provide lubrication to the tendon, is reformed correctly.
Serum metabolomic profiles evaluated after surgery may identify patients with oestrogen receptor negative early breast cancer at increased risk of disease recurrence. Results from a retrospective study (2014)

The performance of a serum metabolomic prognostic model for disease relapse in individuals with ER-negative early stage breast cancer is promising. A confirmation study is ongoing to better define the potential of metabolomics as a host and tumour-derived prognostic tool.
Opioid pharmacology of the antinociceptive effects of loperamide in mice (1994)

Loperamide (0.1-3.2mg/kg i.p.) produced dose-dependent and complete suppression of writhing in the acetic acid-induced writhing assay in mice. Naltrexone (NTX; 0.1-10.0mg/kg s.c.) and its N-methylated derivative quaternary naltrexone (QNTX; 1.0 and 10.0mg/kg s.c.) were roughly equipotent in antagonizing the antinociceptive effects of loperamide. In contrast, NTX was approximately 100-fold more potent than QNTX in antagonizing the antinociceptive effects of the classical mu agonist morphine. Furthermore, the antinociceptive effects of loperamide were not antagonized by central administration of the selective mu antagonist D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH(2) (CTAP; 300ng i.c.v.), or by systemic administration of either the kappa selective antagonist nor-binaltorphimine (nor-BNI; 32.0mg/kg s.c.), or the delta antagonist naltrindole (NTI; 10.0mg/kg s.c.). These doses of CTAP, nor-BNI and NTI were effective antagonists of morphine, the kappa agonist U69,593 and the delta agonist BW 373U86 [(+/-)-4-((R*)-a-((2S*5R*)-4-allyl-2,5-dimethyl-1- piperazinal)-3-hydroxybenzyl)-N, N-diethylbenzamide dihydrochloride], respectively. These results indicate that the antinociceptive effects of loperamide in mice are mediated, at least in part, by opioid receptors; however, these receptors are distinct from the opioid receptors mediating the effects of morphine, U69,593 and BW 373U86. These results are consistent with the hypothesis that loperamide produces its antinociceptive effects by acting, at least in part, at peripheral opioid receptors.

Tunable Electronic Transport Characteristics of Surface-Architecture-Controlled ZnO Nanowire Field Effect Transistors (2008)

Surface-architecture-controlled ZnO nanowires were grown using a vapor transport method on various ZnO buffer film coated c-plane sapphire substrates with or without Au catalysts. The ZnO nanowires that were grown showed two different types of geometric properties: corrugated ZnO nanowires having a relatively smaller diameter and a strong deep-level emission photoluminescence (PL) peak and smooth ZnO nanowires having a relatively larger diameter and a weak deep-level emission PL peak. The surface morphology and size-dependent tunable electronic transport properties of the ZnO nanowires were characterized using a nanowire field effect transistor (FET) device structure. The FETs made from smooth ZnO nanowires with a larger diameter exhibited negative threshold voltages, indicating n-channel depletion-mode behavior, whereas those made from corrugated ZnO nanowires with a smaller diameter had positive threshold voltages, indicating n-channel enhancement-mode behavior.
Multi-Element Unstructured Methodology for Analysis of Turbomachinery Systems (2003)

In recent years unstructured mesh techniques have become popular for computational e uid dynamics analysis of external aerodynamic-type problems. The main advantages of such an approach include mesh generation over complex domains, grid adaptation in localized areas, and accuracy in efe ciently identifying complexities in local e ow physics. A hybrid unstructured methodology is used to carry out simulations for predominantly internal e ow turbomachinery applications. Issues related to skewness and other constraints of tetrahedral meshes are addressed in the context of turbomachinery-based propulsive e ows that exhibit a rich variety of length scales and timescales, as well asinteresting e ow physics. The unstructured framework permits the generation of a contiguous grid without internal boundaries between different components of a turbomachinery system and provides good local resolution in regions where the e ow physics becomes important. The increased numerical stability resulting from these factors coupled with the parallel solution framework yields an efe cient solution procedure for complex turbomachinery e ows. Numerical results are presented and compared against experimental measurements for a transonic diffuser‐ volute cone guration and a high Reynolds number pump.
mTOR-dependent synthesis of Bcl-3 controls the retraction of fibrin clots by activated human platelets (2006)

New activities of human platelets continue to emerge. One unexpected response is new synthesis of proteins from previously transcribed RNAs in response to activating signals. We previously reported that activated human platelets synthesize B-cell lymphoma-3 (Bcl-3) under translational control by mammalian target of rapamycin (mTOR). Characterization of the ontogeny and distribution of the mTOR signaling pathway in CD34+ stem cell-derived megakaryocytes now demonstrates that they transfer this regulatory system to developing proplatelets. We also found that Bcl-3 is required for condensation of fibrin by activated platelets, demonstrating functional significance for mTOR-regulated synthesis of the protein. Inhibition of mTOR by rapamycin blocks clot retraction by human platelets. Platelets from wild-type mice synthesize Bcl-3 in response to activation, as do human platelets, and platelets from mice with targeted deletion of Bcl-3 have defective retraction of fibrin in platelet-fibrin clots mimicking treatment of human platelets with rapamycin. In contrast, overexpression of Bcl-3 in a surrogate cell line enhanced clot retraction. These studies identify new features of post-transcriptional gene regulation and signal-dependant protein synthesis in activated platelets that may contribute to thrombus and wound remodeling and suggest that posttranscriptional pathways are targets for molecular intervention in thrombotic disorders.
Long-term Human Video Activity Quantification of Student Participation (2021)

Research on video activity recognition has been primarily focused on differentiating among many diverse activities defined using short video clips. In this paper, we introduce the problem of reliable video activity recognition over long videos to quantify student participation in collaborative learning environments (45 minutes to 2 hours).Video activity recognition in collaborative learning environments contains several unique challenges. We introduce participation maps that identify how and when each student performs each activity to quantify student participation. We present a family of low-parameter 3D ConvNet architectures to detect these activities. We then apply spatial clustering to identify each participant and generate student participation maps using the resulting detections.We demonstrate the effectiveness by training over about 1,000 3-second samples of typing and writing and test our results over ten video sessions of about 10 hours. In terms of activity detection, our methods achieve 80% accuracy for writing and typing that match the recognition performance of TSN, SlowFast, Slowonly, and I3D trained over the same dataset while using 1200x to 1500x fewer parameters. Beyond traditional video activity recognition methods, our video activity participation maps identify how each student participates within each group.
Effects of Macromolecular Crowding on Human Adipose Stem Cell Culture in Fetal Bovine Serum, Human Serum, and Defined Xeno-Free/Serum-Free Conditions (2017)

Microenvironment plays an important role for stem cell proliferation and diﬀerentiation. Macromolecular crowding (MMC) was recently shown to assist stem cells in forming their own matrix microenvironment in vitro. The ability of MMC to support adipose stem cell (ASC) proliferation, metabolism, and multilineage diﬀerentiation was studied under diﬀerent conditions: fetal bovine serum- (FBS-) and human serum- (HS-) based media and xeno- and serum-free (XF/SF) media. Furthermore, the immunophenotype of ASCs under MMC was evaluated. The proliferative capacity of ASCs under MMC was attenuated in each condition. However, osteogenic diﬀerentiation was enhanced under MMC, shown by increased deposition of mineralized matrix in FBS and HS cultures. Likewise, signiﬁcantly greater lipid droplet accumulation and increased collagen IV deposition indicated enhanced adipogenesis under MMC in FBS and HS cultures. In contrast, chondrogenic diﬀerentiation was attenuated in ASCs expanded under MMC. The ASC immunophenotype was maintained under MMC with signiﬁcantly higher expression of CD54. However, MMC impaired metabolic activity and diﬀerentiation capacity of ASCs in XF/SF conditions. Both the supportive and inhibitory eﬀects of MMC on ASC are culture condition dependent. In the presence of serum, MMC maintains ASC immunophenotype and enhances adipogenic and osteogenic diﬀerentiation at the cost of reduced proliferation.
One-pot synthesis of composite NiO/graphitic carbon flakes with contact glow discharge electrolysis for electrochemical supercapacitors (2015)

Thanks to their high power density and degree of reversibility, supercapacitors are electrochemical devices that narrow the gap between secondary batteries and traditional dielectric capacitors in the traditional Ragone plot. However, their use is still hindered by their capability to achieve higher energy density. In this work, we present a one-pot synthesis procedure of composite graphitic carbon flake-supported NiO for electrochemical energy storage application. We used cathodic contact glow discharge electrolysis by applying 120 Vdc terminal voltage between a thin Pt wire, slightly submerged in an aqueous solution of NiSO4(H2O)6 + Na2SO4, and a large surface area carbon graphite anode. Strong active species generated within the micro-plasma volume locally reduce the nickel precursors to form NiO materials, while at the anodically polarized graphite rod, the forces holding the graphene layers together are weakened by ion/solvent intercalation producing micrometer-sized graphitic carbon flakes. The morphological characterization is carried out by electron microscopy, energy dispersive X-ray spectroscopy, powder X-ray diffraction, and micro-Raman spectroscopy. Cyclic voltammetry, constant-current charge/discharge, and electrochemical impedance spectroscopy in 5 mol l−1 KOH solution are carried out to evaluate the electrochemical energy storage performance of the material. We show that carbon flake-supported NiO exhibits the dual combination of electric double-layer capacitance with faradic behavior, giving 495 F g−1 specific capacitance at 2 A g−1 current density.

Kinetic Analysis of Clostridium cellulolyticum Carbohydrate Metabolism: Importance of Glucose 1-Phosphate and Glucose 6-Phosphate Branch Points for Distribution of Carbon Fluxes Inside and Outside Cells as Revealed by Steady-State Continuous Culture (2000)

During the growth of Clostridium cellulolyticum in chemostat cultures with ammonia as the growth-limiting nutrient, as much as 30% of the original cellobiose consumed by C. cellulolyticum was converted to cellotriose, glycogen, and polysaccharides regardless of the specific growth rates. Whereas the specific consumption rate of cellobiose and of the carbon flux through glycolysis increased, the carbon flux through the phosphoglucomutase slowed. The limitation of the path through the phosphoglucomutase had a great effect on the accumulation of glucose 1-phosphate (G1P), the precursor of cellotriose, exopolysaccharides, and glycogen. The specific rates of biosynthesis of these compounds are important since as much as 16.7, 16.0, and 21.4% of the specific rate of cellobiose consumed by the cells could be converted to cellotriose, exopolysaccharides, and glycogen, respectively. With the increase of the carbon flux through glycolysis, the glucose 6-phosphate (G6P) pool decreased, whereas the G1P pool increased. Continuous culture experiments showed that glycogen biosynthesis was associated with rapid growth. The same result was obtained in batch culture, where glycogen biosynthesis reached a maximum during the exponential growth phase. Glycogen synthesis in C. cellulolyticum was also not subject to stimulation by nutrient limitation. Flux analyses demonstrate that G1P and G6P, connected by the phosphoglucomutase reaction, constitute important branch points for the distribution of carbon fluxes inside and outside cells. From this study it appears that the properties of the G1P-G6P branch points have been selected to control excretion of carbon surplus and to dissipate excess energy, whereas the pyruvate-acetyl coenzyme A branch points chiefly regulate the redox balance of the carbon catabolism as was shown previously (E. Guedon et al., J. Bacteriol. 181:3262-3269, 1999).
Prognostic significance of antithrombin III, plasminogen and proactivator of plasminogen activity in viral hepatitis. (1988)

Antithrombin III/AT III/, plasminogen (Plg) and proactivator of plasminogen [PPlg] activity were studied in 663 patients with various liver diseases and 547 healthy subjects. Parallel analysis of AT III, Plg and PPlg gives a very valuable prognostic information concerning the forthcoming evolution of viral hepatitis [v.h] and acute liver failure. The prognosis of v.h. in the cases with normal Plg activity is independent from the AT III activity in 98% of the cases it is associated with clinical improvement. The combination with low Plg and elevated AT III activity suggested clinical improvement in 65-90% of the patients. Most critical is the combination between low Plg and low AT III activity. This combination suggests clinical aggravation and danger of hepatic coma. The existence of 4 patterns of AT III activity is shown: elevated, normal in physiological condition, normal in pathological condition and decreased activity.
Management of endophthalmitis in a silicone oil-filled eye (1997)

PURPOSE To describe the management of endophthalmitis in an eye filled with silicone oil for prolonged internal retinal tamponade. METHODS A patient with a silicone oil-filled eye developed endophthalmitis postoperatively. Results of clinical examination, diagnostic procedures, and surgical management are described. RESULTS Removal of the silicone oil, injection of antibiotics into the fluid-filled vitreous cavity, and reinjection of silicone oil resulted in resolution of the endophthalmitis and improvement in vision. CONCLUSIONS Aggressive management of endophthalmitis in an eye requiring silicone oil tamponade may salvage useful vision.
Ergodic capacity in mmWave ad hoc network with imperfect beam alignment (2015)

Millimeter wave (mmWave) technology has several technical hurdles to overcome before becoming an integral next-generation wireless technology. One such hurdle is the alignment of the steerable mmWave antenna array. This paper quantifies both the ergodic capacity of a mmWave ad hoc network with perfect alignment and the loss in ergodic capacity when error is introduced. First, we leverage stochastic geometry to evaluate the ergodic capacity (bits/sec/Hz/area) in the network. Next, we compare two antenna models that are commonly used: sectored and Gaussian. Lastly, we derive expressions that quantify the loss in ergodic capacity per user when alignment error occurs at the receiver and transmitter. Our results show that even relatively small errors in alignment can lead to significant ergodic capacity reduction.

A Succeeding Transmission Scheme for Burst Transfer in Optical Burst Switched Networks (2008)

Optical Burst Switched (OBS) networks are considered as promising candidates for the next generation network architecture which does not need high-speed switch technologies. In OBS networks, contention resolution is one of the significant problems. Generally, setup reservations are operated per burst in OBS networks. To transmit multiple successive bursts successfully, the effective wavelength reservation must be implemented and enhanced network performance must be realized. In the proposed method, when an optical burst is generated and its destination is the same as that of the preceding burst or the path until the destination includes the entire path of the preceding burst, the subsequent burst is assigned to the same wavelength as the preceding burst and transmitted sequentially. The main aim in the proposed method is the efficient use of wavelength resources and the reduction of burst loss probability. We simulate and evaluate the effectiveness of the proposed method. As a result, it is verified that the proposed method can reduce the burst loss probably.
<title>Development of object-oriented multimedia database and its application to retrieval of maintenance parts</title> (1994)

Abstract In this paper is presented a method of maintenance part information retrieval, applied to a multimedia database of elevator parts.In design and maintenance sections, there are needs to treat multimedia data suchas images and graphs, used for non-procedural operations, as CAD and office automation systems become disseminated. We developed a prototype system for retrieval of maintenance part information, applied to a multimedia database of elevator parts, to beused for ordering the needed information for maintenance. Conventionally, these neededpart information are searched and ordered by a maintenance engineer with cumbersome process. Namely, the engineer must select appropriate parts according both to the specifications of the elevator to be maintained, and to the description in documents foreach maintenance part.In our system, the elevator parts, which have complex hierarchical structure, are modelled by object-oriented technology. Thus, a maintenance engineer can easily retrieve and order the needed part information, guided by the computer system, utilizing
Ganglioside treatment of neuropathy in diabetic mice (1982)

Abstract Diabetic neuropathy in 180‐day‐old C57BL/Ks inbred mice is characterized by a marked reduction of nerve conduction velocity (NCV) and by axonal atrophy, as suggested by the decreased number of large diameter myelinated fibers. No demyelination or remyelination was observed. Ganglioside treatment from 150 to 180 days of age significantly improved the NCV and returned the fiber size distribution to control values.
Application of a label-free and domain-specific free thiol method in monoclonal antibody characterization (2019)

Characterization of free thiol variants in antibody therapeutics is important for biopharmaceutical development, as the presence of free thiols may have an impact on aggregate formation, structural and thermal stability, as well as antigen-binding potency of monoclonal antibodies. Most current methods for free thiol quantification involve labeling of free thiol groups by different tagging molecules followed by UV, fluorescence or mass spectrometry (MS) detection. Here, we optimized a label-free liquid chromatography (LC)-UV/MS method for free thiol quantification at a subunit level and compared this method with two orthogonal and conventional approaches, Ellman's assay and peptide mapping with differential alkylation. This subunit unit approach was demonstrated to be able to provide domain-specific free thiol quantification and comparable results with labeling approaches, using a relatively simple and efficient workflow.
Investigations of Faulty DRAM Behavior Using Electrical Simulation Versus an Analytical Approach (2005)

Fabrication process improvements and technology scaling results in modifications in the characteristics and in the behavior of manufactured memory chips, which also modifies the faulty behavior of the memory. This paper introduces an analytical (equation-based) method to give a rough analysis of the faulty behavior of cell opens in the memory, that simplifies the understanding and identifies the major factors responsible for the faulty behavior. Having these factors makes it easier to optimize the circuit and allows extrapolation of the behavior of future technologies. The paper also compares the results of the analytical approach with those from the simulation-based analysis and discusses the advantages and disadvantages of both
