Wintel: Cooperation and Conflict (2007)

We study competitive interactions between Intel and Microsoft, two producers of complementary products. In a system of complements, like the PC, the value of the final product depends on how well the different components work together. This, in turn, depends on the firms’ investment in complementary R&D. We ask whether Intel and Microsoft will want to cooperate and make the final product as valuable as possible. Contrary to the popular view that two tight complements will generally have well aligned incentives, we demonstrate that natural conflicts emerge over pricing, the timing of new product releases, and who captures the greatest value at different phases of product generations.
A GIDL free tunneling gate driver for a low power non-volatile memory array (2012)

A recently presented single-poly non-volatile C-Flash memory bitcell provides an ultra-low power low cost option for embedded RFID design. This cell requires the application of a 10V potential difference between the cell's control lines for program and erase operations. Providing the required voltages includes several challenges in the design of the voltage driver, such as the elimination of Gate Induced Drain Leakage (GIDL) currents. In this paper, we present a voltage driver architecture that utilizes novel techniques to overcome the power consumption problems during high voltage propagation. This driver was implemented in the TowerJazz 0.18μm CMOS technology, providing the required functionality with a low static-power figure of 34.6pW.
MPEG-21 in broadcasting: the novel digital broadcast item model (2004)

The MPEG experts are currently developing the MPEG-21 set of standards and this includes a framework and specifications for digital rights management (DRM), delivery of quality of services (QoS) over heterogeneous networks and terminals, packaging of multimedia content and other things essential for the infrastructural aspects of multimedia content distribution. Considerable research effort is being applied to these new developments and the capabilities of MPEG-21 technologies to address specific application areas are being investigated. One such application area is broadcasting, in particular the development of digital TV and its services. In more practical terms, digital TV addresses networking, events, channels, services, programs, signaling, encoding, bandwidth, conditional access, subscription, advertisements and interactivity. MPEG-21 provides an excellent framework of standards to be applied in digital TV applications. Within the scope of this research work we describe a new model based on MPEG-21 and its relevance to digital TV: the digital broadcast item model (DBIM). The goal of the DBIM is to elaborate the potential of MPEG-21 for digital TV applications. Within this paper we focus on a general description of the DBIM, quality of service (QoS) management and metadata filtering, digital rights management and also present use-cases and scenarios where the DBIM’s role is explored in detail.
Antioxidant and Antiproliferative Activities of Raspberries (2002)

Raspberries are rich in phenolic phytochemicals. To study the health benefits of raspberries, four fresh raspberry varieties (Heritage, Kiwigold, Goldie, and Anne) were evaluated for total antioxidant and antiproliferative activities. The total amount of phenolics and flavonoids for each of the four raspberry varieties was determined. The Heritage raspberry variety had the highest total phenolic content (512.7 ± 4.7 mg/100 g of raspberry) of the varieties measured followed by Kiwigold (451.1 ± 4.5 mg/100 g of raspberry), Goldie (427.5 ± 7.5 mg/100 g of raspberry), and Anne (359.2 ± 3.4 mg/100 g of raspberry). Similarly, the Heritage raspberry variety contained the highest total flavonoids (103.4 ± 2.0 mg/100 g of raspberry) of the varieties tested, followed by Kiwigold (87.3 ± 1.8 mg/100 g of raspberry), Goldie (84.2 ± 1.8 mg/100 g of raspberry), and Anne (63.5 ± 0.7 mg/100 g of raspberry). The color of the raspberry juice correlated well to the total phenolic, flavonoid, and anthocyanin contents of the raspberry. Heritage had the highest a/b ratio and the darkest colored juice, and the Anne variety showed the lowest phytochemical content and the palest color. Heritage raspberry variety had the highest total antioxidant activity, followed by Kiwigold and Goldie, and the Anne raspberry variety had the lowest antioxidant activity of the varieties tested. The proliferation of HepG2 human liver cancer cells was significantly inhibited in a dose-dependent manner after exposure to the raspberry extracts. The extract equivalent to 50 mg of Goldie, Heritage, and Kiwigold fruit inhibited the proliferation of those cells by 89.4 ± 0.1, 88 ± 0.2, and 87.6 ± 1.0%, respectively. Anne had the lowest antiproliferative activity of the varieties measured but still exhibited a significant inhibition of 70.3± 1.2% with an extract equivalent to 50 mg of fruit. The antioxidant activity of the raspberry was directly related to the total amount of phenolics and flavonoids found in the raspberry (p < 0.01). No relationship was found between antiproliferative activity and the total amount of phenolics/flavonoids found in the same raspberry (p > 0.05).

Rapid AAV-Neutralizing Antibody Determination with a Cell-Binding Assay (2018)

Recombinant adeno-associated virus (rAAV) has been developed as a successful vector for both basic research and human gene therapy. However, neutralizing antibodies (NAbs) against AAV capsids can abolish AAV infectivity on target cells, reducing the transduction efficacy. Absence of AAV NAb has become a prerequisite qualification for patients enrolled in gene therapy trials. Nevertheless, accurate assessment of AAV NAb has remained a challenging task. Here we developed a rapid assay based on the observations that AAV NAb inhibits rAAV binding to the host cell surface and NAb titers are negatively related to the amount of AAV genomes binding to the target cells. By quantifying the AAV genome on the target cells in the presence of anti-sera, AAV NAb titers can be accurately determined. The titer determined by this assay correlates well with the classical transduction-based assays. A major advantage of this method is that it can be carried out with a 30-min binding assay without the lengthy wait for a transduction outcome. This assay is independent of transduction performance of AAV serotype in the target cells. Therefore, the AAV cell-binding assay for NAb determination offers an alternative method for <i>in vivo</i> NAb assay.
Correction for scatter in 3D brain PET using a dual energy window method (1996)

A method for scatter correction using dual energy window acquisition has been developed and implemented on data collected with a brain-PET tomograph operated in the septa retracted, 3D mode. Coincidence events are assigned to (i) an upper energy window where both photons deposit energy between 380 keV and 850 keV or (ii) a lower energy window where one or both photons deposit within 200 keV and 380 keV. Scaling parameters are derived from measurements of the ratios of counts from line sources due to scattered and unscattered events in the two energy windows in head-sized phantoms. A scaled subtraction of the two energy windows produces a distribution of scatter which is smoothed prior to subtraction from the upper energy window. In phantoms, the correction was found to restore the uniformity, contrast and linearity of activity concentration. Relative activity concentrations were restored to within 7% of their true values in a multicompartment phantom. The method was found to provide accurate correction for scattered events arising from activity outside the direct detector field of view. In a three-compartment phantom containing water, 18F and 11C scanned in dynamic, multiframe mode, the half-lives of the two isotopes were restored to within 2% of their true value.

Abstract An improved method of gravel packing has been used in more than fifty wells in the Gulf Coast area of Texas. It has been proven both economically and mechanically successful for controlling sand at increased oil production rates. The process uses a slurry with extremely high concentrations of gravel in a viscous oil with a "tackifying" agent. The slurry is squeezed into the problem zone until a sandout is obtained. A screen liner is then washed in the hole to keep the gravel in place. Field results and experiences with this technique are discussed in the paper. Success of the process has resulted from packing large volumes of gravel around the wellbores, which allows good drainage and sand control concurrently. Background Sand control has been a persistent problem in the petroleum industry for many problem in the petroleum industry for many years. Numerous techniques have been tried with varying degrees of success, and gravel packing has been one of the most useful ways packing has been one of the most useful ways to solve sand problems. Although a large amount of gravel packing technology has developed, many problems still exist. Through proper use of existing technology, we can control virtually any formation sand with gravel. The major problem has been how to control these sands without restricting fluid production. Most operators are now more critically than ever reviewing their wells with an eye on how to increase production. One potentially profitable way is to use improved potentially profitable way is to use improved gravel packing techniques that will provide improved fluid production as well as sand control. Sand control processes can be only as good as the completion practices used in the well. Often a gravel pack is blamed for many problems which result from a combination of problems which result from a combination of formation characteristics and poor completion practices. practices.
Strategies for Spinal Cord Protection during Descending Thoracic and Thoracoabdominal Aortic Surgery: Up-to-date Experimental and Clinical Results - A review (2002)

Surgery of the descending thoracic and thoracoabdominal aorta, apart from postoperative mortality, is threatened by spinal cord ischemic complications resulting in paraplegia or paraparesis. These, in turn, are associated with an increased risk of postoperative and late mortality. Signie cant advances in understanding the pathogenesis of spinal cord ischemic injury occurring after descending thoracic and thoracoabdominal aortic aneurysm repair hasled tothedevelopment of different strategies,whichinseveral seriesdecreasedthe rate of postoperative paraplegia to below 5%. However, since none of these methods alone seems to reduce to nil the riskof postoperative paraplegia, each ofthemshould be wisely supplemented by other neuroprotective maneuvers or drugs. This review article summarizes the current knowledge originating from experimental and clinical studies and the most signie cant advancements achieved in this e eld during the last decade. Furthermore, some of the mostusedsurgical approaches are presented in their fundamental steps.
Introduction (1994)

Experience with patients, doctors, medical students, and over a million electrocardiograms (EKGs) has shown two things: First, it is still true that many people are leading miserable and unnecessarily restricted lives because electrocardiography is not being used to its greatest advantage,1,2 and second, this could be corrected easily. The plan of this book is to explain these views, and suggest that correction calls for nothing more than recognition that the standards for the practice of electrocardiography are the same as those for any other aspect of medicine.
Design of silane crosslinkable high density polyethylene compounds for automotive fuel tank application (2005)

A formulation was designed to produce silane crosslinkable HDPE compound extrusion blow suitable for extrusion blow molding by melt blending technique on Magicmolding machine. The formulations consist of HDPE as the base polymer, a carrier chemical pack containing an organic unsaturated silane and a free radical generating agent and condensation catalyst. In designing and formulating silane crosslinkable blow molded HDPE compounds with satisfactory properties, ASTM D 2647 was used as the reference. Grafting and crosslinking reaction was proposed for the formulated system. The product was characterized for the chemical, thermal, physical and mechanical properties. The chemical reactions during grafting and crosslinking involved a three step mechanisms. Extrusion blow molded bottle were stored in water for curing at various temperature and time. DSC, FTIR and TGA were used to determine the chemical groups involved in the reactions and gel contents were determined in parallel. The results from curing showed that a further formation of Si-O-Si crosslinkâ€™s took place after the point at which maximum gel contents has been reached. Mechanical measurements indicated that further crosslinkâ€™s were formed within the existing gel. Suitable range concentration relating to 100 parts of base polymer was found for vinyltrimethoxysilane (VTMO) to be between 1.6 to 2.0 phr. The concentration of dicumyl peroxide (DCP) initiator was between 0.1to 0.5 phr. The concentration of dibutyltin dilaurate (DBTL condensation catalyst) was being 0.005 to 0.02. When the DBTL amount was less than 0.005 phr, the crosslinking reaction did not proceed sufficiently. As the DBTL amount was larger than 0.02 phr, local crosslinking proceeds in the extruder at the time of extrusion, results in great deterioration of the products. The selected components used in the formulation are HDPE grade HB6200, vinyltrimethoxysilane (VTMO) as the crosslinking agent, dicumyl peroxide (DCP) as the initiator, dibutyltin dilaurate (DBTL) as the condensation catalyst and Irganox 1010 as the antioxidant. The blow molded bottle properties and processability of the compound depends on the formulation and process parameter. 
Permeation rate of the fuel decreased proportionally with the addition of EVOH in PE structures. By taking the minimum rate of 1.14 gram petrol/day, it has clearly stated that the wall layer complies the EPA emissions regulations saying that a vehicle must emit no more than a total of 2.0 gram of hydrocarbon; measured during the diurnal ( 24 hours ) cycle. Also when using diesel as fuel, implementing EVOH content of 1% and 0.5mm off thickness, the permeation rate required by the standard of 0.35 gram/day is already achieved.
THE INFLUENCE OF OXYGEN AND INOSITOL ON THE SURVIVAL OF SEMIDRIED MICROORGANISMS (1967)

Oxygen was found to have no effect on the induction of the λ prophage due to desiccation but enhanced cell death and the inactivation of the intracellular phages at relative humidity (R.H.) levels below 40%. The magnitude of the oxygen effect increased as the R.H. below 30% decreased. Inositol prevented cell death and phage inactivation due to both bound water reorientation and oxidations. Cells freeze-dried before aerosolization were more stable to storage in air at 30% R.H. and below than they were at 40% to 70% R.H. However, most of the killing of pre-dried cells held at 20% R.H. and below in air was found to be due to an effect of oxygen.
COMPLEMENTARITY : AN UNDERCURRENT IN THE HISTORY OF HUMAN RESOURCE MANAGEMENT IN JAPAN (1995)

The modernization of human resource management in Japanese industry was realized by way of introduction of various systems from advanced Western countries. The basic philosophy underlying such modern human resource management systems is anchored in the concept of dichotomy.Needless to say, F.W. Taylor's scientific management system is the foremost example of this : the status and role of those in management and those subjected to management are sharply divided. Management monopolizes the power to decide about every minute detail of operation : those at the bottom of the hierarchy just are supposed to obey orders from above.Introduction of Taylor's system into Japanese industry took place in the 1920's, and 1930's, against the background of a fierce debate on how to evaluate scientific management within the Japanese context. One group of industrial engineers argued that workers at the work shop level should be treated not as mere objects of time and motion study, but rather as equal partner in any such study.These engineers attached prime importance to the rich implicit knowledge which workers naturally have on how to improve their own operations. In other word, according to this group of engineers there ought to be no dichotomy between the roles of shop-level workers and engineers; instead they preferred considering these respective roles as mutually complementary.The author wondered what was the origin of the concept of complementarity in Japan. His hypothesis implies that this concept has been an undercurrent of Japanese business philosophy since the middle of the Edo Period, around 1700-1800. Ideas about complementarity between management and labour were typically formulated in the works of thinkers like Ando Shoeki, Ishida Baigan, Ninomiya Sontoku and Tanaka Kyugu; Section II and III of this paper provide on evaluation of such works. Then, in Section IV the author proceeds to analyze the complementarity related philosophy and behavior of business leaders like Ohara Magosaburo, Shibusawa Eiichi and so forth who were active in the 1920's, and 1930's. In addition, Section IV also covers some representative examples of complementarity-based business patterns in the period after WW II, including a few cases of superior performance levels in the development of new car models in the automotive industry.Section V, finally, stresses the author's conviction that the concept of complementarity is not unique to Japan, but rather is of universal value.
Triple helices formed at oligopyrimidine*oligopurine sequences with base pair inversions: effect of a triplex-specific ligand on stability and selectivity (1998)

Oligonucleotide-directed triple helix formation is mostly restricted to oligopyrimidine*oligopurine sequences of double helical DNA. An interruption of one or two pyrimidines in the oligopurine target strand leads to a strong triplex destabilisation. We have investigated the effect of nucleotide analogues introduced in the third strand at the site opposite the base pair inversion(s). We show that a 3-nitropyrrole derivative (M) discriminates G*C from C*G, A*T and T*A in the presence of a triplex-specific ligand (a benzo[e]pyridoindole derivative, BePI). N6-methoxy-2,6-diaminopurine (K) binds to an A*T base pair better than a T*A, G*C or C*G base pair. Some discrimination is still observed in the presence of BePI and triplex stability is markedly increased. These findings should help in designing BePI-oligonucleotide conjugates to extend the range of DNA sequences available for triplex formation.
