A Custom Shade Guide System for Composite Resins (1990)

Shade guides that are included in most composite kits are not made of the actual resin material. Therefore the true shade, translucency, or opacity of the composite resin is not readily apparent with stock shade guides. Due to this fact, it has become evident that the best solution to the shade guide problem is to construct a custom shade guide from the actual resin. Until recently, fabrication of custom shade guides has been a time-consuming, inefficient task. Now, a simple and efficient method of forming accurate shade guides for composites is available. With its unique handle/template design, T-TABs enable a dentist to create a precise, labeled shade guide within minutes. There are many advantages to both dentist and patient when T-TABs are employed in the construction of custom shade guides.
Evaluation of premature senescence and senescence biomarkers in carcinoma cells and xenograft mice exposed to single or fractionated irradiation (2014)

The purpose of the present study was to elucidate whether premature senescence contributes to the outcome of radiotherapy (RT) and to validate senescence biomarkers in vitro and in vivo. Cultured human cancer cell lines and xenografted mice were exposed to single (SR; 2, 6 or 12 Gy) or fractionated radiation (FR; 3 x 2 Gy or 6 x 2 Gy), and premature senescence was assessed using senescence-associated β-galactosidase (SA-β-Gal) activity, hypophosphorylation of pRb and p21 accumulation. A variety of senescence-associated biomarkers including cathepsin D (CD), the eukaryotic translation elongation factors eEF1A1, eEF1B2, decoy receptor 2 and Dec1 were further validated in vivo or in vitro. We demonstrated the beneficial tumor suppressive role of ionizing radiation (IR)-induced premature senescence in vitro and in vivo. FR inhibited tumor growth via induction of premature senescence as effectively as an equivalent SR dose (≥6 Gy). In addition, CD and eEF1 were valuable biomarkers of cellular senescence in either SR- or RF-exposed carcinoma cells or xenograft mice. Our results suggest that 2 Gy of a conventional RT regime could achieve a better clinical outcome if premature senescence could be increased through an improved understanding of its molecular action mechanism.
The viscous flow on surfaces with longitudinal ribs (1989)

The viscous sublayer of a turbulent boundary layer on a surface with fine longitudinal ribs (riblets) is investigated theoretically. The mean flow constituent of this viscous flow is considered. Using conformal mapping, the velocity distributions on various surface configurations are calculated. The geometries that were investigated include sawtooth profiles with triangular and trapezoidal grooves as well as profiles with thin blade-shaped ribs, ribs with rounded edges and ribs having sharp ridges and U-shaped grooves. (This latter riblet configuration is also found on the tiny scales of fast sharks.) Our calculations enable us to determine the location of the origin of the velocity profile that lies somewhat below the tips of the ridges. The distance between this origin and the tip of the ridge we call ‘protrusion height’. The upper limit for the protrusion height is found to be 22% of the lateral rib spacing; the coefficient 0.22 being the value of the expression π −1 In 2. This limit is valid for two-dimensional riblet geometries. Analogous experiments with an electrolytic tank are carried out as an additional check on the theoretical calculations. This is also an easy way to determine experimentally the location of the origin of the velocity profile for arbitrary new riblet geometries. A possible connection between protrusion height and drag reduction in a turbulent boundary layer flow is discussed. Finally, the present theory also produces an orthogonal grid pattern above riblet surfaces which may be utilized in future numerical calculations of the whole turbulent boundary layer.
A Hypothesis-Testing Approach Toward Identifying Active Contrasts (1996)

The problem of identifying the active contrasts in an unreplicated fractional factorial design is approached from a hypothesis-testing point of view. The null hypothesis that all contrasts are inactive is first tested and, if rejected, the active contrasts causing rejection are identified and estimated. The method is illustrated with examples from Box and Meyer, compared with the confidence-interval approach of Dong and Lenth, and found to be a worthy competitor.
Experimental and Computational Study of a Direct O<sub>2</sub>-Coupled Wacker Oxidation: Water Dependence in the Absence of Cu Salts (2010)

The kinetics of the Pd[(-)-sparteine]Cl(2) catalyzed oxidation of decene using oxygen as the sole oxidant have been studied in the absence of copper salts and high [Cl(-)]. Saturation kinetics are observed for [decene] as well as a third order dependence on [water]. A mechanism is proposed involving the dissociation of two chlorides and rate-limiting formation of a three-water hydrogen bridged network and subsequent oxypalladation as supported by computational studies.
Effects of Peruvian Anchovy (Engraulis ringens) Meal Supplemented with Santoquin on Growth and Fishy Flavor of Broilers (1969)

THE high biological value of most fish meals for poultry has been recognized for many years (Robertson et al., 1940; Rhian, 1941; Almquist, 1957). A high quality fish meal is an excellent source of protein (Hinners and Scott, 1960) and of essential amino acids (Almquist, 1957). Also, fish meal and fish products contain unidentified growth factors for poultry (Heuser and Norris, 1951; Atkinson and Couch, 1951). However, the development of fishy flavor of broiler meat has been associated to diets containing high levels of fish meal or fish oil. Cruickshank (1939) found that a 15% low grade fish meal plus 2% cod liver oil caused a definite fishy flavor. More recently, Hardin et al. (1964) also showed that off flavors were produced with a combination of 15 % fish meal and 1.5% added stabilized fish oil which resulted in a total of 1.8% dietary fish oil. Fishy and off flavors…
Vision based people tracking for ubiquitous Augmented Reality applications (2009)

The task of vision based people tracking is a major research problem in the context of surveillance applications or human behavior estimation, but it has had only minimal impact on (Ubiquitous) Augmented Reality applications thus far. Deploying stationary infrastructural cameras within indoor environments for the purpose of Augmented Reality could provide a users' devices with additional functionality that a small device and mobile sensors cannot provide to its user. Therefore people tracking could be expected to become an ubiquitously available infrastructural element in buildings since surveillance cameras are widely used. The use for scenarios indoors or close to buildings is obvious. We present and discuss several different ways where people tracking in real-time could influence the fields of Augmented Reality and further vision based applications.
A Review of Hybrid ARQ in 4G LTE (2015)

Long Term Evaluation (LTE) technology is the most efficient mobile broadband technology for providing an excellent user experience. The 3rd Generation Partnership Project (3GPP), Release’8 LTE provides the next step of 3G technology. LTE offers cogent improvements over previous technologies like GSM/UMTS/HSPA. Lower latency, higher downlink & uplink speeds, and simpler network architecture are among, other new features that are provided. This paper presents a survey on hybrid ARQ (HARQ) types and mechanisms which is the core feature that provides robustness in LTE and Advance LTE networks.
Perceptually valid facial expression blending using expression units (2007)

The human face is a rich source of information regarding underlying emotional states. Facial expressions are crucial in showing the emotions as well as increasing the quality of communication and speech comprehension. The detailed study of facial actions involved in the expression of the six universal emotions [1] has helped the computer graphics community develop realistic facial animations. Yet the visual mechanisms by which these facial expressions are altered or combined to convey more subtle information remains less well understood by behavioural psychologists and animators. This lack of a strong theoretical basis for combining facial actions has resulted in the use of ad-hoc methods for blending facial expression in animations [2--3]. They mainly consider the facial movements for transient or combined expressions a simple mathematical function of the main expressions involved. The methods that have emerged are therefore computationally tractable, but the question of their "perceptual" and "psychological" validity has not yet been answered. Examples of such methods are "Sum of two expressions with or without limits," "Weighted averaging," and "MAX operator".
α‐Amylase adsorption on starch crystallites (1991)

The goal of this work was to characterize the adsorption of Bacillus subtills alpha-amylase onto crystalline starchy materials of the B-type polymorph. Monodisperse spherulitic particles (R approximately equal to 5.0 microm), essentially resistant to alpha-amylolysis at 25 degrees C were prepared from short amylose chains (DP(n) approximately equal to 15). The alpha-amylase adsorbed specifically onto the spherulites, and adsorption was found to be a prerequisite step for hydrolysis. Adsorption was inhibited by the presence of maltose and maltotriose in the reaction mixture. Adsorption isotherm of the enzyme on the particles showed a well developed plateau of 1.62 microg/cm(2) at 25 degrees C corresponding to a monolayer adsorption process. The binding free energy calculated from the initial slope of the isotherm was DeltaG approximately equal to -20.7 kJ/mol. This is smaller than published values for the binding of alpha-amylase to soluble amylosic chains (DeltaG < -30 kJ/mol).
Vaccine breakthrough hypoxemic COVID-19 pneumonia in patients with auto-Abs neutralizing type I IFNs (2022)

Life-threatening "breakthrough" cases of critical COVID-19 are attributed to poor or waning antibody (Ab) response to SARS-CoV-2 vaccines in individuals already at risk. Preexisting auto-Abs neutralizing type I IFNs underlie at least 15% of critical COVID-19 pneumonia cases in unvaccinated individuals; their contribution to hypoxemic breakthrough cases in vaccinated people is unknown. We studied a cohort of 48 individuals (aged 20 to 86 years) who received two doses of a messenger RNA (mRNA) vaccine and developed a breakthrough infection with hypoxemic COVID-19 pneumonia 2 weeks to 4 months later. Ab levels to the vaccine, neutralization of the virus, and auto-Abs to type I IFNs were measured in the plasma. Forty-two individuals had no known deficiency of B cell immunity and a normal Ab response to the vaccine. Among them, 10 (24%) had auto-Abs neutralizing type I IFNs (aged 43 to 86 years). Eight of these 10 patients had auto-Abs neutralizing both IFN-α2 and IFN-ω, whereas two neutralized IFN-ω only. No patient neutralized IFN-β. Seven neutralized type I IFNs at 10 ng/ml and three at 100 pg/ml only. Seven patients neutralized SARS-CoV-2 D614G and Delta efficiently, whereas one patient neutralized Delta slightly less efficiently. Two of the three patients neutralizing only type I IFNs at 100 pg/ml neutralized both D614G and Delta less efficiently. Despite two mRNA vaccine inoculations and the presence of circulating Abs capable of neutralizing SARS-CoV-2, auto-Abs neutralizing type I IFNs may underlie a notable proportion of hypoxemic COVID-19 pneumonia cases, highlighting the importance of this particularly vulnerable population.
An Effective Strategy, Applicable to <i>Streptococcus salivarius</i> and Related Bacteria, To Enhance or Confer Electroporation Competence (1999)

Despite the large number of techniques available for transformation of bacteria, certain species and strains are still resistant to introduction of foreign DNA. Some oral streptococci are among the organisms that can be particularly difficult to transform. We performed a series of experiments that involved manipulation of growth and recovery media and cell wall weakening, in which the electroporation conditions, cell concentration, and type and concentration of the transforming plasmid were varied. The variables were optimized such that a previously untransformable Streptococcus salivarius strain, ATCC 25975, could be transformed reproducibly at a level of 10(5) transformants per microg of DNA. The technique was used to introduce a plasmid into other strains of S. salivarius, including a fresh isolate. Moreover, the same technique was applied successfully to a wide range of oral streptococci and other gram-positive bacteria.

Identification of Neisseria gonorrhoeae by genetic transformation: a clinical laboratory evaluation (1977)

Transformation of a Neisseria gonorrhoeae auxotroph (uracil and arginine deficient) to prototrophy was attempted with wild-type deoxyribonucleic acid from 71 random clinical N. gonorrhoeae cultures. Of these 71 cultures, 97.1% transformed the nutritionally deficient mutant to prototrophy. The procedure was reliable and economical and offered several distinct advantages over other methods used for the confirmation of N. gonorrhoeae.

The glutamatergic compounds sarcosine and N-acetylcysteine ameliorate prepulse inhibition deficits in metabotropic glutamate 5 receptor knockout mice (2010)

These findings provide evidence that the interactions between mGluR5 and NMDA receptors are involved in the regulation of PPI and suggest that activation of glutamate receptors, other than group II receptors, by increased endogenous glutamate transmission, may ameliorate the behavioral abnormalities associated with mGluR5 deficiency.
A Paradigm for Physical Interaction with Sound in 3-D Audio Space (2006)

Immersive virtual environments offer the possibility of natural interaction with a virtual scene that is familiar to users because it is based on everyday activity. The use of such environments for the representation and control of interactive musical systems remains largely unexplored. We propose a paradigm for working with sound and music in a physical context, and develop a framework that allows for the creation of spatialized audio scenes. The framework uses structures called soundNodes, soundConnections, and DSP graphs to organize audio scene content, and offers greater control compared to other representations. 3-D simulation with physical modelling is used to define how audio is processed, and can offer users a high degree of expressive interaction with sound, particularly when the rules for sound propagation are bent. Sound sources and sinks are modelled within the scene along with the user/listener/performer, creating a navigable 3-D sonic space for sound-engineering, musical creation, listening and performance.
High data rate switch with amplifier chip (1999)

A critical component for high bandwidth communications links is a digital switch. Desirable features of a digital switch include: high input/output bandwidth, high channel count, scalability, low latency and interchannel skew. Superconductive circuits, with simultaneous high speed and low power advantages (even including the requisite cryocooler) have been applied to a highly scaleable crossbar switch, useful in supercomputer networks, massively parallel processing (MPP), and high data rate telecommunications. We report here on the testing of a 16/spl times/16 switch chip based on the switch chip component of the highly scaleable crossbar system. We have successfully transmitted multi-Gb/s data through this superconducting switch, with packet destination addressing decoded from the header of the data packet. The data are transmitted to a separate superconducting amplifier chip, mounted on a superconducting multi-chip module with the switch. The switch is a crossbar architecture, voltage state design, and operated to beyond 3 Gb/s. The amplifier is a clocked latching stack of Josephson junctions. Output of the amplifier at 6.2 Gb/s is 7.0 mV, which facilitates the interface of the module to its users. BER of the two-chip assembly is 10/sup -9/ or less above 2 Gb/s.

An infrastructure for the evaluation and comparison of information retrieval systems (2006)

Even though information retrieval systems have been successfully deployed for over 45 years, the field continues to evolve in performance, functionality, and accuracy. There are hundreds of different products available with different indexing and retrieval characteristics. How does one choose the appropriate system for a given application? The first step in that choice is the creation of a framework for comparison of IR products and an infrastructure that supports automated execution and analysis of testing results. The next step is providing an environment for subjective measurement using human evaluators. In this paper we briefly introduce the concepts used in IR system evaluation and report on our initial implementation of a framework for evaluating indexing performance. We also report a test case, which provides a comparative analysis of the indexing characteristics for three IR system implementations using a common collection of documents.
Towards a Framework for Android Security Modules: Extending SE Android Type Enforcement to Android Middleware (2012)

Smartphones and tablets have become an integral part of our daily life. They increasingly store and process security and privacy sensitive data which makes them attractive targets for attackers. In particular for the popular Android OS, a number of security extensions have been proposed that target specific security and privacy problems caused by Android’s lack of a fine-grained, dynamic and system-wide mandatory access control. In this paper, we tackle the challenge of providing a generic security architecture for the Android OS that can serve as a flexible and effective ecosystem to instantiate different security solutions. In contrast to prior work our security architecture, termed FlaskDroid, provides mandatory access control simultaneously on both Android’s middleware and kernel layers in a consolidated manner. The synchronization of policy enforcement between the two layers is non-trivial due to their completely different semantics. We present an efficient policy language (inspired by SELinux) tailored to the specifics of Android’s middleware semantics. We show the flexibility of our architecture by policy-driven instantiations of selected security models: one is from the existing work (Saint) while the other one is a new privacy-protecting, userdefined and fine-grained per-app access control model. Other possible instantiations include phone booth mode, or dual persona phone. Finally we evaluate our implementation on SE Android 4.0.4 illustrating its efficiency and effectiveness. 1.

Mobile Medical Data Synchronization on Cloud-Powered Middleware Platform (2016)

Our research focuses on supporting patients (persons with mild hemophilia) to self-manage injuries in cases of minor incidents. This involves bi-directional exchanges of the Electronic Health Record (EHR) between patients and the care facility. However, mobile devices rely on wireless communication channels (e.g., Wi-Fi, 3.5/4G, etc.) to transmit data and these channels can experience sporadic disconnections due to bandwidth fluctuations and user mobility. As a result, the collected medical data may not be transmitted back to the Health Information system (HIS) in soft-real time. Further, when new updates are submitted by the patients who are disconnected (remote and offline), synchronization can fail; leading to decision-making based on outdated or incomplete information. In this work, we focus on how to ensure efficient synchronization of the EHR in unreliable mobile environments. This work took advantage of the ubiquitous nature of mobile cloud computing and proposes a middleware, which facilitates efficient process of medical data synchronization, and with minimal latency. The work details state-of-the-art architecture of the cloud-based middleware that is built and tested for real-world use following four methodologies namely: reflective, tuple space, context-awareness, and event-based.
