Pre-Congestion Notification Using Single Marking for Admission and Termination (2007)

Pre-Congestion Notification described in [I-D.eardley-pcn-architecture
]draft-eardly-pcn-architecture-00 and earlier in [I-D.briscoe-tsvwg-
cl-architecture] approach proposes the use of an Admission Control
mechanism to limit the amount of real- time PCN traffic to a
configured level during the normal operating conditions, and the use
of a Flow Termination mechanism to tear-down some of the flows to
bring the PCN traffic level down to a desirable amount during
unexpected events such as network failures, with the goal of
maintaining the QoS assurances to the remaining flows. In [I-D
.eardley-pcn-architecture], Admission and Flow Termination use two
different markings and two different metering mechanisms in the
internal nodes of the PCN region. This draft proposes a mechanism
using a single marking and metering for both Admission and Flow
Termination, and presents a preliminary analysis of the tradeoffs. A
side-effect of this proposal is that a different marking a nd metering
Admission mechanism than that proposed in [I-D.eardley-pcn-
architecture] may be also feasible, and may result in a number of
benefits. In addition, this draft proposes a migration path for
incremental deployment of this approach as an intermediate step to the
dual-marking approach.

Weber rotation total hip replacement: a prospective 5- to 20-year followup study. (2004)

Between 1974 and 1989, 315 primary total hip replacements (274 patients) were done using the cemented Weber Rotation prosthesis and standardized operative technique, which was modified for the stem in 1978. After the first postoperative year, all patients had routine clinical and radiologic examinations at 2-year intervals. Twenty-one patients (22 hips) were lost to followup. At the most recent followup, 30 of 293 hips (253 patients) had been revised: 24 hips for aseptic loosening, five hips for infection, and one hip for a femoral fracture. Survivorship analyses with revision for aseptic loosening as an end point for the 315 hips showed 93% and 78% survival after 10 and 15 years, respectively. Separate survival analyses for the socket showed 99% and 89% survival after 10 and 15 years, respectively. The stem had a survival of 94% and 81%, respectively, during the same time. Survival at 15 years with radiologic evidence of loosening as an end point was 85% for the socket and 72% for the stem. The cementing technique and the design of the acetabular component significantly influenced the rate of loosening. Survivorship analyses with revision for aseptic loosening of the socket, using a modified second generation cementing technique and a hemispheric socket, showed 100% survival after 10 years and 98% after 13 years.
REAL-TIME X-RAY INSPECTION OF WHEAT FOR INFESTATION BY THE GRANARY WEEVIL, SITOPHILUS GRANARIUS (L.) (2004)

A high-resolution real-time x-ray imaging system was assembled using a low-energy, high-current x-ray source,a low-energy x-ray image intensifier, and a CCD camera interfaced to a PC. Overall system resolution was measured at 5 linepairs per mm (100 .m), sufficient for identifying infestations of the granary weevil, Sitophilus granarius (L.) in kernels of wheat.The field of view for imaging of the system was 6 cm2, large enough to image approximately 350 kernels of grain in a single frame.The exposure time for a single frame was 149 ms, yielding a maximum potential throughput rate of around 2500 kernels persecond. For this study, 1500 wheat kernels were x-rayed, both on film and with the system described above. Of the imagedkernels, 682 contained infestations ranging in maturity from the egg to the adult life stage of the granary weevil, while 818 wereuninfested. Both film and digital images were presented to human subjects to compare recognition of the infested kernels.Overall recognition results averaged 84.4% for the images from the intensifier system vs. 90.2% for the film observations.However, when considering only infestations more advanced than the 3rd larval instar, errors for both sets of images fell below2% and were not significantly different.
Electrical Characterization and Reliability of Split-Gate High-Voltage Transistors (2018)

20 to 40 V-rated split-gate n-channel transistors realized in a 90 nm Bipolar-CMOS-DMOS mixed technology are presented. Current-voltage and capacitance-voltage characteristics are measured and some relevant figures of merit are given with special attention to global (driving, switching and conduction) energy losses. The reliability of the devices, as limited by the degradation induced by hot carriers, is investigated.
An ultra-high-density high-speed loadless four-transistor SRAM macro with a dual-layered twisted bit-line and a triple-well shield (2002)

We have developed two schemes for improving access speed and reliability of a loadless four-transistor (4T) SRAM cell: a dual-layered twisted bit line, which reduces coupling capacitance between adjacent bit lines in order to achieve high-speed read/write operations; and triple-well shielding, which protects the memory cell from substrate noise and alpha particles. We incorporated these technologies in a 0.18-/spl mu/m CMOS process and fabricated a 16-Mb SRAM macro with a 1.9-/spl mu//sup 2/ memory cell. This macro fully functions at 400 MHz and has an access time of 2.35 ns.
Three-Input Majority Logic Gate and Multiple Input Logic Circuit Based on DNA Strand Displacement (2013)

In biomolecular programming, the properties of biomolecules such as proteins and nucleic acids are harnessed for computational purposes. The field has gained considerable attention due to the possibility of exploiting the massive parallelism that is inherent in natural systems to solve computational problems. DNA has already been used to build complex molecular circuits, where the basic building blocks are logic gates that produce single outputs from one or more logical inputs. We designed and experimentally realized a three-input majority gate based on DNA strand displacement. One of the key features of a three-input majority gate is that the three inputs have equal priority, and the output will be true if any of the two inputs are true. Our design consists of a central, circular DNA strand with three unique domains between which are identical joint sequences. Before inputs are introduced to the system, each domain and half of each joint is protected by one complementary ssDNA that displays a toehold for subsequent displacement by the corresponding input. With this design the relationship between any two domains is analogous to the relationship between inputs in a majority gate. Displacing two or more of the protection strands will expose at least one complete joint and return a true output; displacing none or only one of the protection strands will not expose a complete joint and will return a false output. Further, we designed and realized a complex five-input logic gate based on the majority gate described here. By controlling two of the five inputs the complex gate can realize every combination of OR and AND gates of the other three inputs.
An Electromagnetic Method of Orienting a Gun Perforator in Multiple Tubingless Completions (1971)

Abstract In multiple tubingless completions, two or more strings of casing are run and cemented in the same borehole. In order to perforate one string and avoid damaging adjacent strings, it is necessary to orient the perforating gun away from adjacent strings. Orienting systems which have been used include the mechanical method, the radioactive multiple line method, and the radioactive single line or density method. The electromagnetic orienting tool is a new approach to the problem of orienting a gun perforator. It operates by detecting adjacent strings based on their magnetic properties. This method is not affected by properties. This method is not affected by cement or formation density since it responds only to magnetic material. No radioactive sources or radiation detectors are used. This tool has been field-tested for several months with good results and a high degree of reliability. Having a diameter of 1-11/16" O.D., the tool will pass through 2-3/8" O.D. tubing and successfully orient in 4-1/2" O.D. casing. Introduction A method of completing a well with multiple zones consists of running two or more strings of casing in a side by side relationship, into a well bore which penetrates all the zones. In normal practice penetrates all the zones. In normal practice all strings are run to about the same depth. In order to produce a particular zone, a gun perforator is run into one of the strings of perforator is run into one of the strings of casing and placed opposite the zone to be produced. The gun must be of the type which produced. The gun must be of the type which fires in a single direction and must be directed so that other casing strings will not be perforated. In this manner each zone may be produced independently from a different casing string. In order to perforate one string and avoid damaging adjacent strings, it is necessary to orient the perforating gun away from the adjacent strings. Orienting systems which have been used include the mechanical method, the radioactive source method using multiple lines, and the radioactive single line or density method. The mechanical method has become obsolete because of inflexibility and high cost. The multiple line radioactive method accurately locates adjacent strings but has the disadvantage that all strings must be entered with wire lines.

Assessment of gene promoter G-quadruplex binding and modulation by a naphthalene diimide derivative in tumor cells (2014)

Naphthalene diimide (NDI) derivatives have shown high affinity for telomeric guanine (G)‑quadruplexes and good antiproliferative activity in different human tumor experimental models. A trisubstituted compound (H‑NDI‑NMe2) has been reported to stabilize the telomeric G‑quadruplex and to cause telomere dysfunction and downregulation of telomerase expression. We further investigated its mechanism of action by analyzing the capability of the molecule to interfere with the expression levels of oncogenes, such as MYC, telome-rase reverse transcriptase (TERT), KIT and BCL2, known to bear G‑quadruplex‑forming sequences within their promoters, in human tumor cell lines of different histological origin. Exposure to H‑NDI‑NMe2 resulted in a cell type‑dependent perturbation of the expression levels of the four selected genes. Biophysical and molecular analyses revealed that H‑NDI‑NMe2 bound with high affinity and effectively stabilized mainly MYC and BCL2, which share long sequences and the possibility of multiple G‑quadruplex folding. The mRNA levels of both genes, but not protein amounts were affected by NDI treatment. Global gene expression analysis showed modulation of genes implicated in telomere function and mechanisms of cancer; however, G‑quadruplex‑mediated regulation of gene expression by H‑NDI‑NMe2 was largely dependent on the cell context. These data indicate that a deeper knowledge on the molecular mechanisms and biological effects of G‑quadruplex structures is still needed to help developing new effective anticancer agents.
A Thermodynamic Perspective of Negative-Capacitance Field-Effect Transistors (2017)

Physical phenomena, underlying operation of negative capacitance field-effect transistors (NCFETs), are treated within a unified simulation framework. The framework incorporates the Landau mean-field treatment of free energy of a ferroelectric (FE) and the polarization dynamics according to Landau-Khalatnikov (LK) equation. These equations are self-consistently solved with the 1-D metal-oxide- semiconductor structure electrostatics and the drift-diffusion solution for currents in the semiconductor channel. Numerical simulations show that, depending on the strength of depolarization field, both regimes of hysteresis switching and of higher on-currents and steeper subthreshold slope with a negligible hysteresis can be delivered by NCFETs under the steady-state condition due to either multiple local energy minima or a single global energy minimum in the free energy landscape. The transient behavior of NCFETs is also studied by the viscosity coefficient in LK equation, and it is found that when the FE response becomes too slow, a significant hysteresis effect on currents shows up even for a free energy landscape with a single global energy minimum. Finally, recent experimental measurements on transient NC in an FE capacitor are discussed. It is shown that those results on transient NC can be due to the mismatch between free charge and polarization driven by the negative curvature of FE thermodynamic energy profile during polarization switching and cannot lead to a transient charge-boost in a hysteresis-free NCFETs.
Job Phasing Aware Preemption Deferral (2011)

Preemptions account for a non-negligible overhead during system execution. There has been substantial amount of research on estimating the delay incurred due to the loss of working sets in the processor state (caches, registers, TLBs) and some on avoiding preemptions, or limiting the preemption cost. We present an algorithm to reduce preemptions by further delaying the start of execution of high priority tasks in fixed priority scheduling. Our approaches take advantage of the floating non-preemptive regions model and exploit the fact that, during the schedule, the relative task phasing will differ from the worst-case scenario in terms of admissible preemption deferral. Furthermore, approximations to reduce the complexity of the proposed approach are presented. Substantial set of experiments demonstrate that the approach and approximations improve over existing work, in particular for the case of high utilisation systems, where savings of up to 22% on the number of preemption are attained.
Copolymers of <i>N</i>-Vinylpyrrolidone and Sulfonate Monomers (1989)

This chapter describes the synthesis, kinetics, and solution properties for copolymers of N-vinylpyrrolidone (NVP) with sulfonate ionic and zwitterionic monomers. Examples of the sulfonate ionic monomers are sodium styrenesulfonate (NaSS) and sodium acrytamido-2-methylpropanesulfonate (NaAMPS); an example of the zwitterionic sulfonate monomer is (2-hydroxyethyl)dimethyl(3-sulfopropyl)-ammonium inner salt, methacrylate (SPE). The NVP-NaAMPS monomer pair was exceptional, showing evidence for donor-acceptor character and an alternating tendency in copolymerization. The NVP copolymers containing simple sulfonate ionic monomers (e.g., NaAMPS) showed polyelectrolyte solution properties. On the other hand, the NVP copolymers with zwitterionic sulfonate monomers showed "antipolyelectrolyte" solution behavior.
Dynamic Phosphoproteomics Uncovers Signaling Pathways Modulated by Anti-oncogenic Sphingolipid Analogs (2018)

The anti-neoplastic sphingolipid analog SH-BC-893 starves cancer cells to death by down-regulating cell surface nutrient transporters and blocking lysosomal trafficking events. These effects are mediated by the activation of protein phosphatase 2A (PP2A). To identify putative PP2A substrates, we used quantitative phosphoproteomics to profile the temporal changes in protein phosphorylation in FL5.12 cells following incubation with SH-BC-893 or the specific PP2A inhibitor LB-100. These analyses enabled the profiling of more than 15,000 phosphorylation sites, of which 958 sites on 644 proteins were dynamically regulated. We identified 114 putative PP2A substrates including several nutrient transporter proteins, GTPase regulators (<i>e.g.</i> Agap2, Git1), and proteins associated with actin cytoskeletal remodeling (<i>e.g.</i> Vim, Pxn). To identify SH-BC-893-induced cell signaling events that disrupt lysosomal trafficking, we compared phosphorylation profiles in cells treated with SH-BC-893 or C2-ceramide, a non-vacuolating sphingolipid that does not impair lysosomal fusion. These analyses combined with functional assays uncovered the differential regulation of Akt and Gsk3b by SH-BC-893 (vacuolating) and C2-ceramide (non-vacuolating). Dynamic phosphoproteomics of cells treated with compounds affecting PP2A activity thus enabled the correlation of cell signaling with phenotypes to rationalize their mode of action.
Range pasture benefits through tree removal (1973)

At Hopland during the 11 years of range improvement study, the total increase in ronch income through livestock use was $133.60 per acre. This value takes into account $57.09 per acre production value without improvement and treatment costs of $34.87. Thus, by reducing the woody plant component of the watershed and replacing it with herbage that livestock could use, the product values were increased fourfold. It should be noted that no fertilizer was applied in this improvement study —and that its use would probably have given a greater magnitude of production increase. It is also expected that this higher level of production can be sustained with a minimum of maintenance costs.
Affective Computing and Autism (2006)

This article highlights the overlapping and converging goals and challenges of autism research and affective computing. We propose that a collaboration between autism research and affective computing could lead to several mutually beneficial outcomes--from developing new tools to assist people with autism in understanding and operating in the socioemotional world around them, to developing new computational models and theories that will enable technology to be modified to provide an overall better socioemotional experience to all people who use it. This article describes work toward this convergence at the MIT Media Lab, and anticipates new research that might arise from the interaction between research into autism, technology, and human socioemotional intelligence.
In vitro construction of bacteriophage lambda carrying segments of the Escherichia coli chromosome: selection of hybrids containing the gene for DNA ligase. (1975)

DNA from lambdagt-lambdaB bacteriophage was cleaved with EcoRI endonuclease and fragments from EcoRI-digested E. coli DNA were inserted. This DNA was used to infect E. coli, and phages containing the gene for DNA ligase were isolated by genetic selection. Two different hybrids were found with the same E. coli segment inserted in opposite orientations. Both hybrids produced similar levels of ligase as measured in crude extracts of infected cells.
The Influence of Patient-Related Factors and the Position of the Acetabular Component on the Rate of Dislocation after Total Hip Replacement* (1997)

The senior one of us performed 438 primary and 181 revision total hip arthroplasties with use of so-called modern prostheses between July 1983 and January 1994. Fifty-three patients, who had had forty-seven primary procedures and twelve revisions, either died or were lost to follow-up less than two years after the operation and were excluded from the study. The results for the remaining 446 patients (391 primary procedures and 169 revisions) were analyzed to determine the influence of patient-related and operative factors and the position of the acetabular component on the rate of dislocation. Dislocation occurred after thirty-two (6 per cent) of the 560 total hip arthroplasties: seventeen (4 per cent) of the 391 primary procedures and fifteen (9 per cent) of the 169 revisions (p = 0.046). There was no relationship between the variables of age, gender, obesity, or preoperative diagnosis and dislocation after either primary or revision arthroplasty. Seven (23 per cent) of the thirty arthroplasties in the patients who had a history of excessive intake of alcoholic beverages (more than 2.1 liters [seventy-two ounces] of beer or more than 0.2 liter [six ounces] of other alcoholic beverages a day) were followed by a dislocation compared with twenty-five (5 per cent) of the 530 arthroplasties in the patients who did not have such a history. This difference was significant for the patients who had had a revision arthroplasty (p = 0.00005), but with the numbers available we could not detect a difference for those who had had a primary arthroplasty (p = 0.264). Radiographic analysis was performed for thirty-two hips that had dislocated and thirty-two that had not (seventeen primary procedures and fifteen revisions in each group), matched exactly according to the type of prosthesis and the operative approach (but not age). We detected no association between either the version or the abduction angle of the acetabular component (within the range of 39 to 56 degrees for the primary prostheses and 38 to 57 degrees for the revision prostheses) and the risk of dislocation. Thirty of the thirty-two hips in each group had an abduction angle of the acetabular component that was in the so-called safe range of 30 to 50 degrees.
