Thrombolytic therapy for acute ischemic stroke: 3 h and beyond (2005)

The current status of thrombolytic therapy approved by the US Food and Drug Administration is intravenous recombinant plasminogen activator given within 3 h of the onset of ischemic stroke. Intra-arterial therapy is possible for up to 6 h but is not Food and Drug Administration-approved for this purpose. Based on current radiologic methods (i.e., magnetic resonance imaging and perfusion computed tomography scans), it is being increasingly realized that the time window for effective thrombolytic therapy is variable, and salvageable tissue in the form of the ischemic penumbra may exist for longer periods of time and could therefore offer a greater time window based on these imaging studies. Development of an effective neuroprotective drug would greatly enhance the stability of the penumbra and offer further opportunities for extending the time window for reperfusion.
The significance of allelic deletions and aneuploidy in colorectal carcinoma (1997)

A combination of clinicopathologic and molecular biologic variables may identify patients at high risk for death from disseminated colorectal carcinoma.
Fibre‐optical microendoscopy (2014)

Microendoscopy has been an essential tool in exploring micro/nano mechanisms in vivo due to high-quality imaging performance, compact size and flexible movement. The investigations into optical fibres, micro-scanners and miniature lens have boosted efficiencies of remote light delivery to sample site and signal collection. Given the light interaction with materials in the fluorescence imaging regime, this paper reviews two classes of compact microendoscopy based on a single fibre: linear optical microendoscopy and nonlinear optical microendoscopy. Due to the fact that fluorescence occurs only in the focal volume, nonlinear optical microendoscopy can provide stronger optical sectioning ability than linear optical microendoscopy, and is a good candidate for deep tissue imaging. Moreover, one-photon excited fluorescence microendoscopy as the linear optical microendoscopy suffers from severe photobleaching owing to the linear dependence of photobleaching rate on excitation laser power. On the contrary, nonlinear optical microendoscopy, including two-photon excited fluorescence microendoscopy and second harmonic generation microendoscopy, has the capability to minimize or avoid the photobleaching effect at a high excitation power and generate high image contrast. The combination of various nonlinear signals gained by the nonlinear optical microendoscopy provides a comprehensive insight into biophenomena in internal organs. Fibre-optical microendoscopy overcomes physical limitations of traditional microscopy and opens up a new path to achieve early cancer diagnosis and microsurgery in a minimally invasive and localized manner.
Very dense N∗N wavelength routers based on a new diffraction grating configuration (1997)

Dense N*N Wavelength Routers were designed based on diffraction grating technology. A 22*22 router with 0.8 nm spacing, 2.4 dB losses, and -40 dB crosstalk was manufactured. We show the possibility of making devices with much smaller spacings.
The BRASSINOSTEROID INSENSITIVE1–LIKE3 Signalosome Complex Regulates <i>Arabidopsis</i> Root Development   (2013)

Brassinosteroid (BR) hormones are primarily perceived at the cell surface by the leucine-rich repeat receptor-like kinase brassinosteroid insensitive1 (BRI1). In Arabidopsis thaliana, BRI1 has two close homologs, BRI1-LIKE1 (BRL1) and BRL3, respectively, which are expressed in the vascular tissues and regulate shoot vascular development. Here, we identify novel components of the BRL3 receptor complex in planta by immunoprecipitation and mass spectrometry analysis. Whereas BRI1 associated kinase1 (BAK1) and several other known BRI1 interactors coimmunoprecipitated with BRL3, no evidence was found of a direct interaction between BRI1 and BRL3. In addition, we confirmed that BAK1 interacts with the BRL1 receptor by coimmunoprecipitation and fluorescence microscopy analysis. Importantly, genetic analysis of brl1 brl3 bak1-3 triple mutants revealed that BAK1, BRL1, and BRL3 signaling modulate root growth and development by contributing to the cellular activities of provascular and quiescent center cells. This provides functional relevance to the observed protein-protein interactions of the BRL3 signalosome. Overall, our study demonstrates that cell-specific BR receptor complexes can be assembled to perform different cellular activities during plant root growth, while highlighting that immunoprecipitation of leucine-rich repeat receptor kinases in plants is a powerful approach for unveiling signaling mechanisms with cellular resolution in plant development.
Predicting Student Performance and Its Influential Factors Using Hybrid Regression and Multi-Label Classification (2020)

Understanding, modeling, and predicting student performance in higher education poses significant challenges concerning the design of accurate and robust diagnostic models. While numerous studies attempted to develop intelligent classifiers for anticipating student achievement, they overlooked the importance of identifying the key factors that lead to the achieved performance. Such identification is essential to empower program leaders to recognize the strengths and weaknesses of their academic programs, and thereby take the necessary corrective interventions to ameliorate student achievements. To this end, our paper contributes, firstly, a hybrid regression model that optimizes the prediction accuracy of student academic performance, measured as future grades in different courses, and, secondly, an optimized multi-label classifier that predicts the qualitative values for the influence of various factors associated with the obtained student performance. The prediction of student performance is produced by combining three dynamically weighted techniques, namely collaborative filtering, fuzzy set rules, and Lasso linear regression. However, the multi-label prediction of the influential factors is generated using an optimized self-organizing map. We empirically investigate and demonstrate the effectiveness of our entire approach on seven publicly available and varying datasets. The experimental results show considerable improvements compared to single baseline models (e.g. linear regression, matrix factorization), demonstrating the practicality of the proposed approach in pinpointing multiple factors impacting student performance. As future works, this research emphasizes the need to predict the student attainment of learning outcomes.
Lifetime-sensitive modulo scheduling in a production environment (2001)

This paper presents a novel software pipelining approach, which is called Swing Modulo Scheduling (SMS). It generates schedules that are near optimal in terms of initiation interval, register requirements, and stage count. Swing Modulo Scheduling is a heuristic approach that has a low computational cost. This paper first describes the technique and evaluates it for the Perfect Club benchmark suite on a generic VLIW architecture. SMS is compared with other heuristic methods, showing that it outperforms them in terms of the quality of the obtained schedules and compilation time. To further explore the effectiveness of SMS, the experience of incorporating it into a production quality compiler for the Equator MAP1000 processor is described; implementation issues are discussed, as well as modifications and improvements to the original algorithm. Finally, experimental results from using a set of industrial multimedia applications are presented.
Loss recovery techniques for transmission of MPEG video over ATM networks (2002)

Cell loss is a critical problem for transmission of video over ATM networks. We first introduce a structural method for packing MPEG video bit-stream into ATM cells. With this method, the impact of cell loss can be limited to the lost cells only. A compensation method called the modified boundary matching algorithm is then proposed for recovery of the lost video information. Simulation results demonstrate that the proposed method yields satisfactory results even when the cell loss rate is very high.

Heat Transfer in Rotating Rectangular Cooling Channels AR=4 With Dimples (2003)

As the world of research seeks ways of improving the efficiency of turbomachinery, attention has recently focused on a relatively new type of internal cooling channel geometry, the dimple. Preliminary investigations have shown that the dimple enhances heat transfer with minimal pressure loss. An investigation into determining the effect of rotation on heat transfer in a rectangular channel (aspect ratio=4:1) with dimples is detailed in this paper. The range of flow parameters includes Reynolds number Re=5000-40000, rotation number Ro=0.04-0.3 and inlet coolant-to-wall density ratio Δρ/ρ=0.122. Two different surface configurations are explored, including a smooth duct and dimpled duct with dimple depth-to-print diameter δ/Dp ratio of 0.3. A dimple surface density of 10.9 dimples/in2 was used for each of the principal surfaces (leading and trailing) with a total of 131 equally spaced hemispherical dimples per surface; the side surfaces are smooth. Two channel orientations of β=90 and 135 deg with respect to the plane of rotation are explored to determine channel orientation effect. Results show a definite channel orientation effect, with the trailing-edge channel enhancing heat transfer more than the orthogonal channel. Also, the dimpled channel behaves somewhat like a 45 deg angled rib channel, but with less spanwise variations in heat transfer.
Analysis in Cos-1 cells of processing and polyadenylation signals by using derivatives of the herpes simplex virus type 1 thymidine kinase gene. (1983)

Bal31 nuclease was used to resect the herpes simplex virus type 1 thymidine kinase (tk) gene from its 3' end, and a plasmid, pTK206, was isolated that lacked the processing and polyadenylation signals normally found at the 3' end of the gene. The wild-type gene, pTK2, and pTK206 were each transferred to pSV010, a plasmid containing the simian virus 40 (SV40) origin of DNA replication, allowing replication and analysis of the patterns of transcription in Cos-1 cells. Fragments of DNA containing processing and polyadenylation signals from SV40 and polyoma virus were inserted into the 3' end of the resected tk gene, pTK206. We found that tk gene expression requires a processing and polyadenylation signal, that signals from SV40 and polyoma virus could substitute for the herpes simplex virus tk signal, and that considerable differences in the levels of tk mRNA were present in Cos-1 cells transfected by these gene constructs. In addition, tk gene expression was restored to a low level after the insertion of an 88-base-pair fragment from the middle of the SV40 early region. Processing and polyadenylation do not occur in the vicinity of this fragment in SV40, even though it contains the hexanucleotide 5'-AAUAAA-3'.
Improved fed-batch bioprocesses using chemically modified amino acids in concentrated feeds (2013)

Background Fed-batch culture bioprocesses are essential for the production of therapeutic proteins [1]. In these cultures, concentrated feeds are added during cultivation to prevent nutrient depletion and to extend the growth phase, thus increasing product concentration [2]. One limitation arises from the low solubility of some amino acids at high concentrations, in particular tyrosine [3]. This amino acid is commonly solubilized in separate feeds at basic pH [4] inducing pH spikes and precipitation when added in the bioreactor. This work describes the evaluation of several chemically modified tyrosines as alternative to simplify fed-batch bioprocesses by using single feeding strategies at neutral pH.
IPS‐mode dynamic LCD‐TV realization with low black luminance and high contrast by adaptive dynamic image control technology (2005)

Abstract— In this paper, an active backlight control technology and a data‐processing algorithm has been developed to improve the image quality in IPS‐mode LCD TVs. The image‐blinking problem caused by repeatedly abrupt changes in the backlight luminance was solved by using algorithms [Fba (flexible‐boundary algorithm) and Cfa (cumulative feedback algorithm)] and an optimized number of backlight dimming steps based on human perception. In the IPS‐mode 42‐in. TFT‐LCD panel, the dynamic contrast ratio can be more than twice the typical level by means of a lower black luminance and a higher white luminance. Additionally, the power consumption and LCD temperature were lowered.
A system for rapid, automatic shader level-of-detail (2015)

Level-of-detail (LOD) rendering is a key optimization used by modern video game engines to achieve high-quality rendering with fast performance. These LOD systems require simplified shaders, but generating simplified shaders remains largely a manual optimization task for game developers. Prior efforts to automate this process have taken hours to generate simplified shader candidates, making them impractical for use in modern shader authoring workflows for complex scenes. We present an end-to-end system for automatically generating a LOD policy for an input shader. The system operates on shaders used in both forward and deferred rendering pipelines, requires no additional semantic information beyond input shader source code, and in only seconds to minutes generates LOD policies (consisting of simplified shader, the desired LOD distance set, and transition generation) with performance and quality characteristics comparable to custom hand-authored solutions. Our design contributes new shader simplification transforms such as approximate common subexpression elimination and movement of GPU logic to parameter bind-time processing on the CPU, and it uses a greedy search algorithm that employs extensive caching and upfront collection of input shader statistics to rapidly identify simplified shaders with desirable performance-quality trade-offs.
Driving Control of Autonomous Vehicles with Vehicle-to-Vehicle Communication (1990)

A vehicle following system by autonomous vehicles with vehicle-to-vehicle communication, named a soft-linked vehicle system, is described. Each vehicle in the system has functions of autonomous navigation based on dead reckoning, and the vehicle-to-vehicle communication for soft-linking. The dead reckoning system uses both wheel speeds of each vehicle measured by rotary encoders. The vehicles are driven linked on a string with constant and small gaps by the vehicle-to-vehicle communication without couplers of hardware, or run independently from each other. The purpose of the system is flexibility and efficiency. Velocity control of vehicles under soft-linking is formulated to a pole assignment problem to maintain the gaps and to avoid collisions between vehicles. Steering control of a vehicle is determined by a target point following algorithm. Steering on a vehicle at the head of a string is controlled so as to hit a series of target points successively which are put along a route. On each of following vehicles steering control is found based on data of its preceding vehicle by the algorithm. Data necessary to the soft-linking are a control input, velocity, position and orientation of the preceding vehicle, which are transmitted through the vehicle-to-vehicle communication. A medium for the communication is infrared, and the data transmission rate is 9600 bps., A vehicle used in this study is a battery-powered automated, guided vehicle of 1.3m×0.75m. Experimental results of the soft-linked vehicle system by two vehicles on driving along a straight line and a lane changing maneuver at the velocity of 0.4m/s show that the velocity and steering control proposed in this paper is effective to the soft-linking.
A Fragment of Triosephosphate Isomerase Competes with the Vasoactive Intestinal Polypeptide (VIP) for Binding to the VIP Receptor. (1991)

A 28-residue N-terminal fragment of triosephosphate isomerase, TIM(1-28), has been purified from porcine upper intestine. It competes with VIP for binding to the VIP receptor on rat liver plasma membranes with an IC50 value of 2.8 mM, about 1000 times higher than that for VIP binding to the membranes. Except for a single positional identity and the number of amino acid residues, the amino acid sequences of TIM(1-28) and VIP are unrelated as regards primary structure. However, the ability to bind to the same receptor site may indicate common three-dimensional structural properties.
Interactive Tire Designs (1975)

The principle of utilizing geometric interaction between runway asperities and tire pattern design is discussed, and a theoretical basis is presented for substantial enhancement of frictional effects by this process. Test data confirming this is given. First order analytical expressions are given for the increased friction coefficients and for the engagement distances required. High-speed friction data on a 7.00 × 8 aircraft tire is presented confirming this. Example design geometries are shown for the tire tread groove pattern, and designs and materials are discussed for the asperity grid and its attachment system.
Selective Utilization of Actuator for a Humanoid Robot by Singular Configuration (2007)

In general, robot should not be operated while it is in a singular configuration since operation degenerates its degrees of freedom. However, humanoid robots are capable of performing tasks while in a state of singular configuration because humanoid robots have many degrees of freedom. In this paper, new task method is proposed for humanoid robots, featuring selective utilization of their actuators while in the singular configuration. First, we define the effective singular configuration for a task and introduce a classification for joints. Next, we propose a method to identify the joint as effectively having a singular configuration. Finally, we demonstrate physical simulation results that include leading a robot in the singular configuration through the task. The advantages of the proposed method are that it supports economizing the robot's energy consumption and applies more power to the hand.
Plasticity in the motor system related to therapy-induced improvement of movement after stroke (1999)

Neuroplasticity might play a beneficial role in the recovery of function after stroke but empirical evidence for this is lacking thus far. Constraint-induced (CI) therapy was used to increase the use of a paretic upper extremity in four hemiparetic stroke patients. Dipole modeling of steady-state movement-related cortical potentials was applied before and after training and 3 months later. The source locations associated with affected hand movement were unusual at follow-up because activation of the ipsilateral hemisphere was found in the absence of mirror movements of the unaffected hand. This long-term change may be considered as an initial demonstration of large-scale neuroplasticity associated with increased use of the paretic limb after application of CI therapy.
MIDP 2.0 security enhancements (2004)

Java 2 Micro Edition (J2ME) is a runtime environment for resource-constrained environments. There are already millions of J2ME enabled mobile devices that support the first version of the Mobile Information Device Profile (MIDP) in J2ME. Many security threats exist in MIDP 1.0 environment since the specification addresses only a limited number of security issues. It is supposed that the next version of the MIDP will have more secure environment for mobile business and personal applications and solve the important security problems in MIDP 1.0. In this paper, we give short introduction to the J2ME and MIDP environment. Based on existing literature, we explain the threats and security needs in mobile environment for MIDP 1.0 applications. We cover the new security mechanisms and features in MIDP 2.0 and analyze against presented threats, how these address the existing security problems in MIDP 1.0. In this paper, we conclude that MIDP 2.0 improves several different issues in MIDP security. Especially the secure network protocols and signed applications are major improvements. We also conclude that there still exist problems in MIDP 2.0 security, mainly related to the PKI that is part of trusted applications and new secure protocols.
