Oxytocin precipitation of prostaglandin-induced farrowing in swine: determination of the optimal dose of oxytocin and optimal interval between prostaglandin F2 alpha and oxytocin. (1987)

The influence of dose of oxytocin and the interval between prostaglandin (PG) F2 alpha and oxytocin administration on the synchrony of farrowing, the prevalence of intrapartum complications, and the number of pigs dying perinatally was investigated. In study 1, sows were given 10 mg of PGF2 alpha IM on day 112, 113, or 114 of gestation or were not treated. Twenty hours after PGF2 alpha administration, sows were given 0, 5, 10, 20, or 30 USP U of oxytocin IM. Sows treated with PGF2 alpha or PGF2 alpha plus oxytocin had a shorter interval to farrowing than sows not treated or treated with oxytocin alone. Treatment with PGF2 alpha plus 30 U of oxytocin induced the most rapid onset and the greatest synchrony of farrowing, with the mean onset occurring 2.1 +/- 0.4 hours after oxytocin vs greater than 8 hours for all other treatments. Sows treated with 5 or 10 U of oxytocin had a delayed onset and a less synchronous farrowing, compared with sows treated with 0 or 20 U. Day of PGF2 alpha treatment influenced (P less than 0.05) the interval from oxytocin to onset of farrowing. As day during gestation decreased, there was a corresponding decrease in the interval between oxytocin administration and farrowing. Number of interventions to remove retained pigs was not influenced (P greater than 0.05) by day of PGF2 alpha administration. All sows treated with PGF2 alpha followed by oxytocin had a higher rate of manual interventions, compared with that in sows given PGF2 alpha but not oxytocin.(ABSTRACT TRUNCATED AT 250 WORDS)
Alterations of the classic pathway of complement in adipose tissue of obesity and insulin resistance (2007)

Adipose tissue inflammation has recently been linked to the pathogenesis of obesity and insulin resistance. C1 complex comprising three distinct proteins, C1q, C1r, and C1s, involves the key initial activation of the classic pathway of complement and plays an important role in the initiation of inflammatory process. In this study, we investigated adipose expression and regulation of C1 complement subcomponents and C1 activation regulator decorin in obesity and insulin resistance. Expression of C1q in epididymal adipose tissue was increased consistently in ob/ob mice, Zucker obese rats, and high fat-diet-induced obese (HF-DIO) mice. Decorin was found to increase in expression in Zucker obese rats and HF-DIO mice but decrease in ob/ob mice. After TZD administration, C1q and decorin expression was reversed in Zucker obese rats and HF-DIO mice. Increased expression of C1 complement and decorin was observed in both primary adipose and stromal vascular cells isolated from Zucker obese rats. Upregulation of C1r and C1s expression was also perceived in adipose cells from insulin-resistant humans. Furthermore, expression of C1 complement and decorin is dysregulated in TNF-alpha-induced insulin resistance in 3T3-L1 adipocytes and cultured rat adipose cells as they become insulin resistant after 24-h culture. These data suggests that both adipose and immune cells are the sources for abnormal adipose tissue production of C1 complement and decorin in obesity. Our findings also demonstrate that excessive activation of the classic pathway of complement commonly occurs in obesity, suggesting its possible role in adipose tissue inflammation and insulin resistance.
Development and testing of mycelium-based composite materials for shoe sole applications (2025)

This research aims to solve problems of solid waste, resource depletion, and material toxicity in the footwear industry. Mycelium, the root structure of mushrooms, acts as a natural glue and binds together substrate materials as it grows outward, offering opportunities for natural composite development. By utilizing mycelium alongside agricultural waste and other natural materials, a fully biodegradable composite with potential shoe sole applications was created. The 4x2 experimental design tested four mushroom species-- reishi, oyster, king oyster, and yellow oyster --and two fabric levels-- with or without a natural fabric mat for reinforcement. Density and compressive strength were measured, and two-way repeated measures ANOVA tests evaluated the relationships between the independent and dependent variables. For density, there was no significant interaction between fabric and species (p=0.117), but the main effects of both species and fabric were significant (p<0.01 for both variables). The fabric contributed to a lower density overall. A post hoc test on species found that the species can be grouped as (king oyster = oyster) > yellow oyster > reishi. For compressive strength, there was no significant interaction between fabric and species (p=0.938) and no significant effect of fabric (p=0.162), but the main effect of species was significant (p<0.01). A post hoc test found that the species can be grouped as: king oyster > oyster > (reishi = yellow oyster). Density was also found to have a positive and significant linear relationship with compressive strength (p=.000), with higher density leading to higher compressive strength. SEM images helped confirm mycelium growth within the composite and around the substrate materials. A comparison of this material to other materials used in footwear indicated that the mycocomposite requires moderate embodied energy in production and scores fairly well on compressive strength. While it has a lower compressive strength than many existing composites or synthetic materials, its sustainable attributes help balance out its performance limitations. This mycocomposite overall showed good compressive strength and provides opportunities for renewable and biodegradable footwear inputs.
A domain model of WWW browsers (1996)

Domain analysis is the process of identifying and organizing knowledge about some class of problems to support the description and solution of those problems, WWW (World Wide Web) browsers was chosen as the domain to illustrate two different levels of domain analysis. In this work we illustrate a problem oriented domain analysis on the navigational features of WWW browsers and a solution oriented domain analysis on WWW browser caching.
SSIM-Based Quality-on-Demand Energy-Saving Schemes for OLED Displays (2015)

This paper investigates how to precisely transform images displaying color on organic light-emitting diodes (OLEDs) in real time for the purpose of energy-saving that meets the personal viewing quality requirements based on the structural similarity (SSIM) assessment. These methods could be applied to real-time energy-saving transformation of any displaying media, including video playback on OLEDs, and it will save up to 20% of the displaying power consumption based on the predicted SSIM = 0.9, which has very good image quality after the transformation.
Quantitative measurement of saccade amplitude, duration, and velocity (1975)

A method for rapid, accurate measurement of saccade amplitude, duration, and velocity (average and maximum) was developed as a functional test of the extraocular motor system. Recordings were made with a direct-current electro-oculographic system, and data analysis was performed on a laboratory digital computer. Saccade amplitude and duration were found to be linearly correlated in 25 normal subjects, with a mean slope of 2.7 msec per degree over a large amplitude range. In the same subjects, saccade amplitude and velocity (maximum or average) had a nonlinear relationship that was best fit by an exponential equation. The two constants of this equation adequately characterized the relationship between saccade amplitude and velocity and permitted rapid statistical comparison between normal and abnormal subjects.

SETTOFF: A fault tolerant flip-flop for building Cost-efficient Reliable Systems (2012)

Conventional fault tolerance techniques either require big overheads or have limited reliability. We propose a novel fault tolerant flip-flop (SETTOFF) that addresses timing errors and soft errors in one cost-efficient architecture. In SETTOFF, most SEUs are detected by monitoring the illegal transitions at the output of a flip-flop and recovered by inverting the cell state. SETs, timing errors and the other SEUs are detected by a time redundancy-based architecture. For a 10% activity rate, SETTOFF consumes 35.8% and 39.7% more power than a library flip-flop in 120nm and 65nm technologies, respectively. It only consumes about 5.7% more power than the detection based RazorII flip-flop [1]. SETTOFF therefore provides an increased coverage of fault tolerance with only moderate increase in overhead, hence it is suitable for building highly reliable systems at lower cost than the traditional techniques.

Thermal barrier coatings for aircraft engines: History and directions (1995)

Thin thermal barrier coatings for protecting aircraft turbine section airfoils are examined. The discussion focuses on those advances that led first to their use for component life extension and more recently as an integral part of airfoil design. It is noted that development has been driven by laboratory rig and furnace testing corroborated by engine testing and engine field experience. The technology has also been supported by performance modeling to demonstrate benefits and life modeling for mission analysis. Factors which have led to the selection of the current state-of-the-art plasma sprayed and physical vapor deposited zirconia-yttria/MCrAlY TBC's is emphasized in addition to observations fundamentally related to their behavior. Current directions in research into thermal barrier coatings and recent progress at NASA is also noted.
A programming model for GPU-based parallel computing with scalability and abstraction (2009)

In this paper, we present a multi-level programming model for recent GPU-based high performance computing systems. Involving cooperative stream threads and symmetric multiprocessing threads our model gives a computational framework that scales through multi-GPU environments to GPU-cluster systems. Instead of hiding the execution environment from the programmer using compiler extensions or metaprogramming techniques we aim a solution that both enables optimizations and provides abstract problem space mapping with code reusability and virtualization of hardware resources in order to decrease the programming effort. We evaluate an implementation of our model based on CUDA, OpenMP, and MPI2 technologies on a complex practical application scenario and discuss its performance scaling behavior.
Nonlinear effect of an oscillating electric field on membrane proteins (1989)

The nonlinear response of a two-state chemical transition to an oscillating electric field is examined. A reaction for which this analysis is particularly relevant is a conformational transition of a membrane protein exposed to an ac electric field. Even a modest externally applied field leads to a very large local field within the membrane. This gives rise to nonlinear behavior. The applied ac field causes harmonics in the polarization and can cause a dc shift in the state occupancy, both of which can be observed and used to determine kinetic parameters. Fourier coefficients are calculated for the enzyme state probability in the ac field, exactly for infinite frequency, and in powers of the field for finite frequency. Kramers–Kronig relations are proved and response functions are given for the leading terms of the harmonics. The results are extended to the spherical symmetry relevant to suspensions of spherical cells, vesicles, or colloidal particles. If the protein catalyzes a reaction, free energy is transduced from the electric field to the output reaction, even if that reaction is electrically silent. Many transport enzymes are ideal examples. The ac field can cause the enzyme to pump ions or molecules through the membrane against an (electro)chemical potential. The efficiency of this energy transduction can be as high as 25%.
Enhanced Inter-Cell Interference Coordination in Heterogeneous Networks for LTE-Advanced (2012)

Femtocells, a kind of low power nodes in a heterogeneous network for LTE-Advanced, have become an attractive device to offer better system performance and user experience. However, due to co-channel deployments with the macro cell, the home eNB which serves closed subscriber groups will impose serious interference on macro users especially on their PDCCHs which spans over the whole system bandwidth. In this paper, we propose an enhanced ICIC mechanism to suppress such interference by blanking two OFDM symbols. Furthermore, for Release 10 victim users, a novel repetitively designing PDCCH scheme is proposed such that the interference can be avoided effectively. Analysis shows that our approach is backward compatible and can support LTE TDD and FDD systems simultaneously. And simulations demonstrate that satisfying performance can be obtained by using our methods.
Light scattering from fibers: An extension of a single-slit diffraction experiment (1987)

The similarities and differences between diffraction from single slits and scattering from single fibers can be dramatically demonstrated by some simple experiments. Geometrical properties such as fiber size, cross section, tilt, and nonuniformity all contribute to the intricate detail of the diffraction pattern. An examination of the role of the complex refractive index, polarized light, and geometrical effects in scattering phenomena will contribute to a deeper understanding of the interaction of light with small apertures and particles.
Light interaction and quantum transport in atomic chain chirally coupled to a waveguide (2017)

In this work we considered light interaction with two-level quantum systems chirally coupled to a single guided mode with account for a spin-locking effect. The chiral coupling allows achieving asymmetric interaction between the two-level systems, which strongly affects the light scattering of a guided mode of an optical nanofiber by one-dimensional atomic chain. We have also build an analytical model of unidirectional transport of quantum excitation and verified it with modelling of atoms coupled with surface plasmon polariton mode of a metallic nanowire. In particularly, we showed the tolerance of the unidirectionally coupled systems over the positional disorder of the two-level systems.
Dynamic load management for MMOGs in distributed environments (2010)

To support thousands of concurrent players in virtual worlds simulated by contemporary Massively Multiplayer Online Games, most implementations employ static game world partitioning for distributing the load among multiple game server instances. Further, the resources that manage the resulting subregions are statically allocated, independent of the actual game load. As a result, due to the high variability of the user demand, this approach leads to a low resource utilization causing much higher provisioning costs than necessary. In addition, the number of players supported by a region is limited by the maximum load that can be handled by a single server instance.
Heregulin-mediated ErbB2-ERK Signaling Activates Hyaluronan Synthases Leading to CD44-dependent Ovarian Tumor Cell Growth and Migration (2007)

Heregulin (HRG)-induced cell responses are mediated by the ErbB family of tyrosine kinase receptors. In this study we have investigated HRG activation of ErbB2, extracellular signal-regulated kinase (ERK) signaling, and their role in regulating hyaluronan synthase (HAS) activity in human ovarian tumor cells (SK-OV-3.ipl cells). Immunological and biochemical analyses indicate that ErbB2, ErbB3, and ErbB4 are all expressed in SK-OV-3.ipl cells and that ErbB4 (but not ErbB3) is physically linked to ErbB2 following HRG stimulation. Furthermore, our data indicate that the HRG-induced ErbB2.ErbB4 complexes stimulate ErbB2 tyrosine kinase, which induces both ERK phosphorylation and kinase activity. The activated ERK then increases the phosphorylation of HAS1, HAS2, and HAS3. Consequently, all three HAS isozymes are activated resulting in hyaluronan (HA) production. Because HRG-mediated HAS isozyme phosphorylation/activation can be effectively blocked by either AG825 (an ErbB2 inhibitor) or thiazolidinedione compound (an ERK blocker), we conclude that ErbB2-ERK signaling and HAS isozyme phosphorylation/HA production are functionally coupled in SK-OV-3.ipl cells. HRG also promotes HA- and CD44-dependent oncogenic events (e.g. CD44-Cdc42 association, p21-activated kinase 1 activation, and p21-activated kinase 1-filamin complex formation) and tumor cell-specific behaviors in an ErbB2-ERK signaling-dependent manner. Finally, we have found that the down-regulation of HAS isozyme expression (by transfecting cells with HAS1/HAS2/HAS3-specific small interfering RNAs) not only inhibits HRG-mediated HAS phosphorylation/activation and HA production but also impairs CD44-specific Cdc42-PAK1/filamin signaling, cytoskeleton activation and tumor cell behaviors. Taken together, these findings clearly indicate that HRG activation of ErbB2-ERK signaling modulates HAS phosphorylation/activation and HA production leading to CD44-mediated oncogenic events and ovarian cancer progression.
Determination of competency of programmers by classification and ranking using AHP (2015)

Evaluating the learners to determine their proficiency in programming is a challenging task. In this paper, we attempt to automate this task by analyzing dynamic data collected from programming platform through sensors. Since the performance of students in programming course and their assessment depend on multiple criteria, we model the problem of finding the proficiency of student as a Multi Criteria Decision Making (MCDM) problem. We present a novel solution using Analytic Hierarchy Process (AHP) with which each student is classified into one of the expertise levels which represent their competency in a particular programming language. This competency based approach will help course instructors to grade the students. This grading helps the teachers to identify students who are facing difficulties in learning and to guide them to improve their technical skills. We validate our results by comparing them with marks scored by the students in the examination of that course.
Hypersonic Analysis of Mu Space Engineering Spacecraft (Muses-C) Re-Entry Capsule (2019)

During the most recent decade, a quick development of learning in the field of reemergence and planetary passage has brought about numerous critical advances helpful to the understudies, specialists and researchers. The issue related with space flight, interplanetary travel or satellite circle is the physical recuperation or survival of the vehicle and its payload (faculty, instruments, etc.) on the earth surface or planetary surface. For atmospheric planets, the issue includes basically deceleration, streamlined warming and control of the time and area of landing. For non-atmospheric planets, the issue essentially incorporates just deceleration and control of the time and territory of landing. A general delineation of atmospheric and non-atmospheric planetary segment goes before the examinations of the issue. The main objective of this paper is to study and analysis over new re-entry vehicle and their concept of Mu Space Engineering Spacecraft, i.e., MUSES-C, also the other name called as HAYABUSA . Unlike other papers that held analysis only in ground conditions, here various altitudes have been chosen. For the purpose of analysis, we are using a tool called as computational fluid dynamics. Analysis is carried out for earth entry conditions at an angle of attack 0°, and 30°. The Mach number here we are choosing for MUSE-C is 5, 9, 11 and 12. The flow field over MUSE-C entry capsule is computed at hypersonic speeds using commercial CFD software FLUENT for ideal gas model. Viscous flow models are considered for standard flow properties. The key challenge is to capturing the shock wave, shock stand-off distance and properties behind the shock wave accurately by using laminar model. The results that can be compared with previous journal application of the TAU Code to Re-Entry Capsule Concepts. Keywords: MUSES-C, HAYABUSA, CFD, TAU Code, FLUENT
Crystal Interfaces (1964)

An expression for the energy of an interface of general form between two crystals of arbitrary structures and relative orientations is derived in a form suitable for a variational calculation. This variational approach is applied to a one-dimensional interface between two two-dimensional crystals of differing lattice constants. In general there is a minimum in the interfacial energy when the lattice distances in the two crystals are in the ratio of small integers. Particular cases in which the surface potential is either sinusoidal or parabolic are discussed and detailed curves of interfacial energy as a function of lattice misfit are calculated.
Hippocampal or neocortical lesions on magnetic resonance imaging do not necessarily indicate site of ictal onsets in partial epilepsy (1999)

Advances in neuroimaging techniques, particularly high-resolution magnetic resonance imaging (MRI), have proved invaluable in identifying structural brain lesions in patients with epilepsy. The assumption that such focal lesions invariably predict the site of seizure origin may not be correct, however. We report a series of 20 adults with medically intractable partial epilepsy, where high-resolution brain MRI disclosed a unilateral, focal, hippocampal, or neocortical lesion as the only abnormality in each case; nevertheless, based on electroencephalographic (EEG) recordings, ictal onsets arose from a completely different location than that of the MRI lesion. All patients underwent epilepsy surgery, with the operations based on ictal EEG findings, and all were followed at least 2 years after the resection. After the most recent follow-up examination, 50% (10/20) of the patients were completely seizure-free, 35% (7/20) had at least a 75% reduction in the number of seizures, and 15% (3/20) had less than a 75% reduction in the number of seizures. We conclude that the identification of a focal, structural, hippocampal, or neocortical lesion on brain MRI is not always indicative of the site of seizure origin in partial epilepsy. Furthermore, in cases of discordance between MRI and EEG data, a good outcome after epilepsy surgery is possible if EEG ictal onsets are definitive.
