Optical DQPSK video system with heterodyne detection (1991)

An optical heterodyne subcarrier-multiplexed (SCM) quadrature-phase-shift keying (QPSK) system is described that employs differential encoding to transmit multiple video channels. With this differential encoding scheme, only a simple delay-and-multiply demodulator is necessary, considerably reducing the signal processing complexity. The demodulators reproduce the data in a parallel fashion so no baseband demultiplexing or four-level decision circuit is required. This approach also avoids the complications of implementing a carrier recovery circuit (CRC) and a phase-locked loop associated with coherent microwave demodulation schemes. In addition to bandwidth efficiency and simplicity, differential QPSK also provides very good receiver sensitivity. With heterodyne detection, a receiver sensitivity of -41 dBm is achieved.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Mojo Hand enables scientists to more rapidly deploy TALENs for genome editing applications.
Gene- and immunotherapy for hepatocellular carcinoma (2005)

For the minority of patients with hepatocellular carcinoma (HCC), surgical or locally ablative therapies may offer the prospect of cure. However, the majority of patients present with advanced disease, such that treatment with curative intent is no longer possible. For some of these patients, with good hepatic reserve and a patent portal venous system, chemoembolisation may afford a modest survival benefit. The remainder of patients are frequently treated with systemic therapies with palliative intent. However, no drug treatment has yet clearly demonstrated a significant beneficial effect on survival or quality of life. Thus, there is an urgent need for novel approaches. Gene- and immunotherapy approaches using a variety of strategies are in development at present. HCC possesses several characteristics that make it an attractive target for these therapies. This review aims to summarise the approaches to gene- and immunotherapy for HCC, with particular reference to strategies that are entering clinical trials. It will then describe some of the obstacles to the success of these new approaches and provide opinion regarding ongoing and future developments. The challenge remains to design clinical trials to optimally evaluate these agents and allow feedback to the laboratory for their ongoing development.
Impact of self-similarity on wireless data network performance (2002)

In this paper we investigate the impact of traffic patterns on wireless data networks. Modeling and simulation of the cellular digital packet data (CDPD) network of Telus Mobility (a commercial service provider) were performed using the OPNET tool. We use trace-driven simulations with genuine traffic trace collected from the CDPD network to evaluate the performance of the CDPD protocol. This trace tends to exhibit long-range dependent behavior. Our simulation results indicate that genuine traffic traces, compared to traditional traffic models such as the Poisson model, produce longer queues and, thus, require larger buffers in the deployed network's elements.
Strain difference in establishment of mouse embryonic stem (ES) cell lines (1994)

For utilization of the mouse embryonic stem (ES) cells for various purposes, it is desirable that the cell lines are established from various sources such as inbred and mutant mouse strains. So far, however, most ES cell lines used in genetic manipulation have been derived from the 129/Sv strain. We have established ES cell lines from blastocysts of the C57BL/6 strain at high efficiency by use of a fibroblast cell line SL10 as feeder cells, and supplementing the culture medium with 5,000 unit/ml LIF. Using such culture conditions, we have also established a number of ES cell lines from the BALB/c, BXSB/MpJ-Yaa and MRL/Mp-lpr/lpr mouse strains. Procedure for establishment of ES cell lines had to be modified among the mouse strains, indicating the strain difference. For example, only a few stem cell colonies appeared from the BALB/c blastocysts. Stem cells of the BXSB strain were very sensitive to the trypsinization in subculturing. Most of these cell lines had normal karyotype and produced chimeric mice. Several C57BL/6 cell lines contributed to the germ-line. These results indicate that ES cell lines can be established from various mouse strains, but their characteristics are different among strains.
Exciton Storage in a Nanoscale Aharonov-Bohm Ring with Electric Field Tuning (2009)

We study analytically the optical properties of a simple model for an electron-hole pair on a ring subjected to perpendicular magnetic flux and in-plane electric field. We show how to tune this excitonic system from optically active to optically dark as a function of these external fields. Our results offer a simple mechanism for exciton storage and readout.

A Reflectometric Study of the Reaction between Si and  WF 6 during W‐LPCVD on Si and of the Renucleation during the  H 2 Reduction of  WF 6 (1991)

The formation of W through the reduction of WF6 by Si is monitored in situ using a wavelength adjustable reflectometer.The reflectance-time relation can be understood and modeled by assuming island growth and a statistical distributionof the island thickness. The model is supported by SEM and Auger observations. The effect of surface layers like nativeoxides or a plasma treatment on the inhomogeneous Si consumption by the reaction between Si and WF6 (gouging) and itseffect on the reflectance-time relation are understood. The model is also applicable in the case of renucleation during theH2 reduction of WF6. A renucleation step consists of the deposition of Si from SiH4 followed by the Si consumption byWF6. A renucleation step reduces the surface roughing which occurs during the H2 reduction process.
Pulse Power Nickel Metal Hydride Battery (2002)

<div class="htmlview paragraph">EEI bipolar nickel metal hydride batteries and cells were tested under various conditions relevant to consumer and aerospace pulse power applications, with differing power and discharge pulse time requirements. A generic hybrid vehicle specification required that a full scale battery obtain 300,000 life cycles, while being able to deliver 25 kW discharge power after 18 seconds and 30 kW recharge power after 2 seconds. This corresponds to 15 years of normal use. Using this testing procedure, over 300,000 life cycles were obtained (using 25 Wh energy swings, scaled) on single full-capacity cells, with less than 10-15% pulse power capability loss measured. The projected full-sized battery mass was 40 kg and volume was 20 L. Testing of selected cells is continuing. Another test related to an automotive application demonstrated that a 6 Ah cell starting at 50% SOC was capable of being discharged at 200 A for 10 seconds (33C), with an end voltage of 0.945 V. An application involving the use of 1 second discharge pulses demonstrated power densities of about 3 kW / kg and 8.6 kW / L at the single cell and small battery (6 V) levels. About 120,000 cycles were obtained under these conditions. These test cells used thinner electrodes than those related to automotive applications. Based on these data, several alternative pulse power designs are presented.</div>
Mechanisms for bounding vulnerabilities of processor structures (2007)

Concern for the increasing susceptibility of processor structures to transient errors has led to several recent research efforts that propose architectural techniques to enhance reliability. However, real systems are typically required to satisfy hard reliability budgets, and barring expensive full-redundancy approaches, none of the proposed solutions treat any reliability budgets or bounds as hard constraints. Meeting vulnerability bounds requires monitoring vulnerabilities of processor structures and taking appropriate actions whenever these bounds are violated. This mandates treating reliability as a first-order microarchitecture design constraint, while optimizing performance as long as reliability requirements are satisfied. This paper makes three key contributions towards this goal: (i) we present a simple infrastructure to monitor and provide upper bounds on the vulnerabilities of key processor structures at cycle-level fidelity; (ii) we propose two distinct control mechanisms - throttling and selective redundancy - to proactively and/or reactively bound the vulnerabilities to any limit specified by the system designer; (iii) within this framework, we propose a novel adaptation of Out-of-Order Commit for vulnerability reduction, which automatically provides additional leverage for the control mechanisms to boost performance while remaining within the reliability budget.
EMPOWERMENT COMO ELEMENTO PARA EL DESARROLLO EMPRESARIAL. (2022)

En el presente artículo se describen las características de los trabajadores mexicanos y la forma de desarrollar el empowerment dentro de las empresas del país. El cambio acelerado que enfrentan las empresas mexicanas las ha obligado a adoptar nuevas estrategias en la administración del personal, que permitan mantener el desarrollo de la organización dentro de su particular entorno. Algunas empresas, preocupadas por el desempeño de los empleados, atienden a la psique del trabajador mexicano en el contexto laboral, a los factores que lo motivan, sus miedos, la razón de ser de su comportamiento, en quienes se manifiesta inseguridad, temor, búsqueda del anonimato, desconfianza, auto devaluación e individualismo. Las organizaciones que desean ingresar a nuevos esquemas de trabajo requieren hacer una ruptura de paradigmas clásicos en el manejo del personal y considerar que la formación de equipos de trabajo apoya en la obtención de mejores resultados. Uno de los nuevos paradigmas es el empowerment, en el que se reconoce que el empleado tiene poder de decisión e incrementa la responsabilidad sobre su puesto, estos elementos permiten el incremento en la satisfacción y motivación, aumento del compromiso, además de una rápida adaptación al cambio, mejora del entusiasmo y la actitud positiva.
Weakly constrained codes (1997)

The author reports on the performance of a new class of constrained codes, called weakly constrained codes. These codes do not strictly guarantee the imposed channel constraints, but rather generate codewords that violate, with a given (small) probability, the prescribed constraint. Weakly constrained codes are specifically of interest when it is desirable that the code rate R = p/q is very high, requiring codewords of length q > 100.

A Secure Data Self-Destructing Scheme in Cloud Computing (2014)

With the rapid development of versatile cloud services, it becomes increasingly susceptible to use cloud services to share data in a friend circle in the cloud computing environment. Since it is not feasible to implement full lifecycle privacy security, access control becomes a challenging task, especially when we share sensitive data on cloud servers. In order to tackle this problem, we propose a key-policy attribute-based encryption with time-specified attributes (KP-TSABE), a novel secure data self-destructing scheme in cloud computing. In the KP-TSABE scheme, every ciphertext is labeled with a time interval while private key is associated with a time instant. The ciphertext can only be decrypted if both the time instant is in the allowed time interval and the attributes associated with the ciphertext satisfy the key's access structure. The KP-TSABE is able to solve some important security problems by supporting user-defined authorization period and by providing fine-grained access control during the period. The sensitive data will be securely self-destructed after a user-specified expiration time. The KP-TSABE scheme is proved to be secure under the decision l-bilinear Diffie-Hellman inversion (l-Expanded BDHI) assumption. Comprehensive comparisons of the security properties indicate that the KP-TSABE scheme proposed by us satisfies the security requirements and is superior to other existing schemes.
Reader Architectures for Wireless Surface Acoustic Wave Sensors (2018)

Wireless surface acoustic wave (SAW) sensors have some unique features that make them promising for industrial metrology. Their decisive advantage lies in their purely passive operation and the wireless readout capability allowing the installation also at particularly inaccessible locations. Furthermore, they are small, low-cost and rugged components on highly stable substrate materials and thus particularly suited for harsh environments. Nevertheless, a sensor itself does not carry out any measurement but always requires a suitable excitation and interrogation circuit: a reader. A variety of different architectures have been presented and investigated up to now. This review paper gives a comprehensive survey of the present state of reader architectures such as time domain sampling (TDS), frequency domain sampling (FDS) and hybrid concepts for both SAW resonators and reflective SAW delay line sensors. Furthermore, critical performance parameters such as measurement accuracy, dynamic range, update rate, and hardware costs of the state of the art in science and industry are presented, compared and discussed.
Peptide surfactants (Pepfactants) for switchable foams and emulsions (2007)

Abstract We have developed a series of sustainable peptide surfactants (Pepfactants) capable of stabilizing foams and emulsions in a stimuli‐responsive manner, based on the reversible formation of a mechanically strong interfacial film. Under conditions where the interfacially adsorbed peptide forms a mechanically strong ‘film state’, foam or emulsion stabilization occurs as a direct result of the film strength. Under conditions where the interfacially adsorbed peptide forms a mobile ‘detergent state’, foam or emulsion stabilization is either reduced, or does not occur. Preformed foams or emulsions stabilized by Pepfactants undergo rapid phase coalescence when the film state is converted to the detergent state. Switching between film and detergent states is readily and reversibly achieved by a change in the bulk solution composition, such as a change in pH, or the addition or sequestering of metal ions.

Evaluation of an Ultra-High Performance Epoxy Resin Sealant for Wellbore Integrity Applications (2019)

Abstract After drilling each section of a well, cement is placed in the annulus of the casing and the formation. The cement integrity must be ensured during the life cycle of the well or after abandonment. If for any reason, the cement lost its integrity, the consequences could be severe for personnel, equipment, and the environment. When the cement fail, leakages may occur through the cement pathways and sealant materials are used to plug these pathways. This study investigates a temperature activated epoxy resin sealant to evaluate the potential use of this sealant as an alternative to Portland cement in oil and gas wells. This study focuses on analyzing the rheological behavior of the sealant, the effect of temperature on the rheology and the curing time of the sealant, the penetrability of the sealant into small voids, and the blocking efficiency of the sealant. Experimental tests were conducted to evaluate the epoxy resin sealant including rheological measurements, density, injectivity, blocking efficiency, and mechanical properties. The findings of this study show that this sealant has low viscosity and Newtonian rheological behavior, low density as low as water, high injectivity and penetrability even in small gaps, ability to resist differential pressure higher 1000 psi, and extremely high compressive strength. This work demonstrates that epoxy resin sealant can be used effectively and safely in sealing cement voids.
Viability of fibroblasts in a novel probiotic storage media (2010)

Abstract – A number of storage media have been investigated as to their ability to maintain the viability of the periodontal ligament (PDL) cells and thus to permit longer extra‐alveolar periods prior to replantation of avulsed teeth. The aim of the present in vitro study was to evaluate the number of viable PDL cells of avulsed teeth treated by Hank’s Balanced Salt Solutions (HBSS), saline, a novel probiotic solution and milk. Thirty‐six freshly extracted single‐rooted human teeth with closed apices were divided into one of the four experimental groups and two control groups ( N = 6 each). The positive and negative controls corresponded to 0 min and an 8‐h dry time respectively. Following extraction, the coronal 3 mm of PDL tissue was scraped with a #15 scalpel to remove cells that might have been damaged. The experimental teeth were dried for 30 min followed by a 45 min immersion in one of the four experimental media. Each experimental tooth, after drying and soaking, was incubated for 30 min with a 2.5 ml solution of 0.2 mg ml −1 of collagenase CLS II and a 2.4 mg ml −1 solution of dispase grade II in phosphate buffer saline (PBS). The cells were then labelled with 0.4% Trypan blue for determination of viability. The teeth stored in positive control demonstrated the highest number of viable PDL cells followed in rank order by HBSS, saline, Lactobacillus reuteri solution and milk. There was no significant difference in the number of viable PDL cells between HBSS, milk, L. reuteri solution and saline. Within the parameters of this study, it appears that probiotic may be able to maintain PDL cell viability as HBSS, milk, or saline.

Pulsatility improves hemodynamics during fetal bypass. Experimental comparative study of pulsatile versus steady flow. (1994)

The data suggest that pulsatile flow for 30 minutes of bypass in a fetal lamb preparation temporarily prevents the progressive hypoxemia observed under steady-flow bypass. Pulsatile flow allows higher pump flow through a significant decrease in systemic vascular resistances. Individual organ blood flow, including placenta, was significantly higher under pulsatile bypass. With technical improvements in the design of pulsatile devices adapted to more physiological beat rates, pulsatility may become a valuable adjunct to overcome placental dysfunction observed during experimental fetal cardiac surgery.
Tailored Buckling Microlattices as Reusable Light‐Weight Shock Absorbers (2016)

Structures and materials absorbing mechanical (shock) energy commonly exploit either viscoelasticity or destructive modifications. Based on a class of uniaxial light-weight geometrically nonlinear mechanical microlattices and using buckling of inner elements, either a sequence of snap-ins followed by irreversible hysteretic - yet repeatable - self-recovery or multistability is achieved, enabling programmable behavior. Proof-of-principle experiments on three-dimensional polymer microstructures are presented.
Syntheses and photophysical properties of BF<sub>2</sub> complexes of curcumin analogues (2013)

Stable tetracoordinated organoboron complexes as classic fluorescent molecules have found various applications in material and medical sciences. A new class of curcumin-BF2 complexes has been prepared from the condensation of 2,2-difluoro-1,3-dioxaborylpentadione with a variety of aldehydes and its photophysical properties were characterized. Systematic variations were observed in the absorption spectra of these curcumin-BF2 dyes in solutions, which are well correlated with their structural features, including characteristics of the aromatic groups and presence of a para electron-donating substituent. Strong fluorescence that is tunable from 500 to 800 nm via variation of the polarity of the solvent and a moderate to good fluorescence quantum yield ranging from 0.24 to 0.58 in dichloromethane were observed in curcumin-BF2 complexes 1. By contrast, their asymmetrical analogue, curcumin-BF2 complexes 3 exhibit much lower fluorescence quantum yields. Besides their excellent photostabilities, these curcumin-BF2 dyes also show singlet oxygen generating capabilities.
