Abdominal wound disruption. (1975)

Abdominal wound disruption occurred in 6 cases in a series of 2500 consecutive abdominal laparotomies. A prospective study of 900 laparotomies utilizing polyglycolic acid suture material and the Smead-Jones closure technic was carried out over a period of 1 year with a reduction in the incidence of wound disruption from 0.4 to 0.1%. Etiologic factors placing patients in a high-risk category for disruption are identified, and specific prophylactic measures are discussed. Prevention of catastrophic disruption is advocated because of its high mortality rate, averaging 20%.
D-ORAM: Path-ORAM Delegation for Low Execution Interference on Cloud Servers with Untrusted Memory (2018)

Cloud computing has evolved into a promising computing paradigm. However, it remains a challenging task to protect application privacy and, in particular, the memory access patterns, on cloud servers. The Path ORAM protocol achieves high-level privacy protection but requires large memory bandwidth, which introduces severe execution interference. The recently proposed secure memory model greatly reduces the security enhancement overhead but demands the secure integration of cryptographic logic and memory devices, a memory architecture that is yet to prevail in mainstream cloud servers. In this paper, we propose D-ORAM, a novel Path ORAM scheme for achieving high-level privacy protection and low execution interference on cloud servers with untrusted memory. D-ORAM leverages the buffer-on-board (BOB) memory architecture to offload the Path ORAM primitives to a secure engine in the BOB unit, which greatly alleviates the contention for the off-chip memory bus between secure and non-secure applications. D-ORAM upgrades only one secure memory channel and employs Path ORAM tree split to extend the secure application flexibly across multiple channels, in particular, the non-secure channels. D-ORAM optimizes the link utilization to further improve the system performance. Our evaluation shows that D-ORAM effectively protects application privacy on mainstream computing servers with untrusted memory, with an improvement of NS-App performance by 22.5% on average over the Path ORAM baseline.
Nonactive antenna compensation for fixed-array microwave imaging. I. Model development (1999)

Fixed-array microwave imaging with multisensor data acquisition can suffer from nonactive antenna element interactions which cause distortions in the measurements. In Part I of a two-part paper, we develop a nonactive antenna compensation model for incorporation in model-based near-field microwave image reconstruction methods. The model treats the nonactive members of the antenna array as impedance boundary conditions applied over a cylindrical surface of finite radius providing two parameters, the effective antenna radius and impedance factor, which can be determined empirically from measured data. Results show that the effective radius and impedance factor provide improved fits to experimental data in homogeneous phantoms where measurements are obtained with and without the presence of the nonactive antenna elements. Once deduced, these parameters are incorporated into the nonactive antenna compensation model and lead to systematic data-model match improvements in heterogeneous phantoms. While the improvements afforded by the nonactive antenna model are small on a per measurement basis, they are not insignificant. As shown in Part II, inclusion of this new model for nonactive antenna compensation produces significantly higher quality image reconstructions from measurements obtained with a fixed-array data acquisition system over the frequency band 500-900 MHz.

Physical processes control eruption styles, which then dictate what products are available for sampling and how well the eruption sequence can be determined. These erupted products and their ordering in time permit reconstruction of the parental magma chamber. Supervolcanoes also have smaller eruptions that provide snapshots of magma chamber development in the lead-in to and aftermath of supereruptions. Many aspects of supereruption dynamics, although on a vast scale, can be understood from observations or inferences from smaller historic and prehistoric events. However, the great diversity in the timings of supereruptions and in the eruptive behaviour of supervolcanoes present continuing challenges for research.

Efferent Innervation of the Rat Testis1 (1995)

Previous assessments of the autonomic nerve supply of the male genital tract concluded that the testis received sympathetic input primarily from paraaortic ganglia, particularly the spermatic ganglion. We challenged this consensus by using retrograde axonal tracing to examine the source and distribution of efferent fibers reaching the testis of adult rats. We also used immunohistochemical methods to assess putative neurotransmitters in testicular neurons of the abdominal and pelvic ganglia. The results indicate the majority of retrogradely labeled cell profiles were localized within the major pelvic (38%) and pelvic accessory ganglia (37%), and only a few labeled cell profiles were present in the paraaortic and spermatic ganglia. Injection of FluoroGold and Fast Blue dyes into the respective right and left testis demonstrated that 17% of the neurons in pelvic ganglia were labeled when tracers were microinjected beneath the capsule of the contralateral testis. About 8% of the neurons were labeled both with FluoroGold and Fast Blue, suggesting that certain neurons can provide simultaneous input to the left and right testicles. Immunohistochemical results showed that tyrosine hydroxylase, a marker for noradrenergic fibers, was present in over 33% of the cell profiles labeled with either FluoroGold or Fast Blue. Some 27% of the fluorescent-labeled cell profiles were positive for neuropeptide Y, while 22% were immunoreactive for vasoactive intestinal polypeptide. No evidence for vasoactive intestinal polypeptide immunoreactivity was detected within the testis, but neuropeptide Y-immunoreactive fibers were present in the tunica albuginea and testicular vasculature. Catecholamine fluorescent fibers were distributed sparsely throughout the periphery of the testis in association with the capsule, vasculature, and interstitium.(ABSTRACT TRUNCATED AT 250 WORDS)

Myoelectrical signal classification for the hierarchical control of a human hand prosthesis (2010)

Most electrically powered upper limb prostheses are myoelectrically controlled. The myoelectric controllers use surface electromyographical signals as inputs. These signals, collected from the surface of the skin, have to be preprocessed before being used as inputs for the controller. In this paper we present a classifier for surface electromyographical signals based on an autoregressive (AR) model representation and a neural network, and the higher level of the hierarchical controller implemented using Finite State Machine. The results had shown that using a low order autoregressive model combined with feed forward neural networks achieves a rate of classification of 91% while keeping the computational cost low. Using the hierarchical controller, the necessary effort to control the prosthesis by the patient is reduced since the patient only have to initiate the movement which is finalized by the low level part of the controller. The inputs of the high level controller are obtained from the classifier. The outputs of the high level controller are applied as inputs to the low level controller.
Dynamic range of the seismic system (1987)

Dynamic range usually refers to a range of levels within which a system can handle a signal with a specified fidelity or accuracy. The constraints are set by uncontrolled energy, generated in the system itself, which imposes uncertainties and sets limits on the possible range. This uncontrolled energy is of two types. Firstly, there is always noise in the system which is simply added to any signal which passes through the system. Secondly, there is signal distortion; i.e. unwanted signal-dependent energy, which is also generated in the system. The two types of energy are usually referred to as: 1. system noise; 2. noise behind the signal. Typical figures for a seismic instrument are: system noise -0.3uV rms; noise behind the signal-80 db below signal level for signals under 30 uV rms. The recovery of hidden signals will be hampered when their levels fall below the system noise or below a certain threshold under the total signal level. This recovery is partly an absolute and partly a relative matter. The available technical specificatians of the hardware involved, such as the geophones, the cables and the instrument, enable us to easily assess the dynamic range of this hardware. Things become more complex if environmental disturbances are taken into account. If, for example, the source characteristics vary from shot to shot, if geophones have not been planted properly, or if differential statics are present within an array, then these perturbations will distort the ideal case.
Field Emitter Array RF Amplifier Development Project, Phase 1, Option 1 (1994)

Abstract : The program goals of > 5 mA total anode current at current density of > 5 A/cm2 were achieved with a 1,197 tip array. Single tip devices from two separate wafers operated at > 1 microA for over 24 hours. Successful electrical testing was performed on a 44,460 tip array. The in-house DC testing program has evaluated an average of 2.5 devices per workday since July 30, 1993. Out of 139 devices tested, 63 or 45% produced acceptable anode current at gate voltage below 250 V. Refinements continue at various steps in the process flow. More rigorous uniformity requirements have resulted in modification of the initial photolithography steps. Various gate metal systems are being tested to maximize device test performance. Development of low work function and metal coatings has focused on the optimization of the deposition process for tantalum nitride, and the development of processes for lanthanum hexaboride and zirconium carbide. The chemical composition, resistivity, and growth rate of the films is being analyzed. Theoretical calculations of the emission area and field enhancement factor for field emitter arrays were made using data collected from devices tested at MCNC. The resulting data compared favorably with a priori simulation results.
System level performance of CoMP IR-HARQ over X2 interface in 3GPP LTE-Advanced system (2012)

In order to achieve higher data rates and more reliable QoS, coordinated multipoint transmission/ reception (CoMP) is raised in 3GPP release 10 and beyond. Cooperative transmission can effectively improve the performance of cell-edge users with the cost of exchange load between service eNodeB and cooperative eNodeB. Previous work of 3GPP release 11 has noticed the modeling of cooperative backhaul like X2, but research results are still under perfect assumptions during this release. In release 12, demand on modeling of imperfect backhaul has been launched to get a realistic result of CoMP. In this paper, we consider the delay of X2 interface in 3GPP LTE-Advanced systems, the influence of IR-HARQ under perfect and imperfect X2 modeling is given using our system level simulation platform. Simulation results shows that the delay in X2 will cause the delay in MAC layer and the HARQ process in CoMP mode need to be modified to match the feature of delay.
The Failure of ‘Market Failure’ (1987)

Arguments that state intervention in the economy is superior to a policy of laissez‐faire are usually based on the misperception that government will succeed where the market is thought to fail. Alexander Shand, formerly Senior Lecturer in Economics at Manchester Polytechnic, surveys economic theory to demonstrate that the state itself is prone to failure; government intervention is often the cause of deficiencies in the market economy.
Cellular Immunity in Interstitial Cystitis (1991)

It has been suggested that interstitial cystitis is an autoimmune disease. The evidence for this hypothesis, based on studies of humoral immune factors, has been contradictory. We assessed the immune response in interstitial cystitis by evaluating lymphocyte populations in the peripheral blood and bladder tissue of interstitial cystitis patients. The lymphocyte phenotypes in peripheral blood were entirely normal, including the CD4 (cluster designation nomenclature) and CD8 subsets, and the CD4:CD8 ratio. Bladder lamina propria showed a predominance of CD4 over CD8 lymphocytes in interstitial and other forms of cystitis. Bladder epithelium showed a similar pattern in bacterial or mechanical cystitis but specimens from patients with interstitial cystitis had a predominance of CD8 cells. The findings of normal lymphocyte populations in the peripheral blood are not supportive of an autoimmune mechanism in the disease. The findings in bladder tissue show that the urothelium is not involved in the inflammatory reaction, as is the lamina propria, and they would suggest, therefore, that the initiating factor does not originate from the bladder lumen. The CD8 predominance in the urothelium along with a CD4 predominance in the lamina propria may form a characteristic pattern for the diagnosis of interstitial cystitis and merits further study.
Contribution of individual side-chains to the stability of BPTI examined by alanine-scanning mutagenesis (1995)

Bovine pancreatic trypsin inhibitor (BPTI) serves as an important model system for the examination of almost all aspects of protein structure. Systematic studies of the effects of mutation on the thermodynamic stability of BPTI, however, have been limited by the extreme stability of the protein. A derivative of BPTI containing only the 5-55 disulfide bond, termed [5-55]Ala, has been shown previously to fold into a structure very similar to that of native BPTI and to be a functional trypsin inhibitor. [5-55]Ala undergoes a reversible thermal unfolding transition with a melting temperature of 39 degrees C, and is therefore well suited for stability studies. Using an alanine-scanning mutagenesis approach, we have examined the contribution to stability of each side-chain in the [5-55]Ala derivative of BPTI. These studies demonstrate the importance of the two hydrophobic cores composed largely of clusters of aromatic residues, as well as the internal hydrogen-bonding network, in stabilizing BPTI. Overall, there is a strong relationship between change in buried surface area and stability for both polar and hydrophobic residues, with proportionality constants of 50 and 20 cal/A2, respectively. None of the alanine substitutions substantially stabilized [5-55]Ala. Nonetheless, approximately 60% (28/46) of the alanine mutants were destabilized by less than 10 degrees C, suggesting that a form of BPTI with up to half of its residues being alanine could fold into a stable structure resembling the native one.
The carbohydrate structures of a mouse monoclonal IgG antibody OKT3 (1990)

A mouse monoclonal antibody OKT3, of IgG2a isotype, was isolated from hybridoma culture fluid. Sugar analysis showed the presence of sialic acid, galactose, mannose, fucose, and N-acetylglucosamine, i.e. sugars typical for N-glycosidically linked carbohydrate chains. The absence of N-acetylgalactosamine revealed that O-glycosidically linked carbohydrates were not present. The purified antibody was reduced, alkylated, and separated into heavy and light chains, and all carbohydrates were shown to be associated with the heavy chains. The N-linked carbohydrate chains were isolated as alditols using strong alkaline-borohydride degradation and further fractionated on a concanavalin A-Sepharose column and high performance ion exchange chromatography with pulsed amperometric detection. Structural analysis was carried out on the isolated oligosaccharide alditols by chemical analyses, fast atom bombardment mass spectrometry, and 500-MHz 1H NMR spectroscopy. Triantennary and biantenary types of structures were found. The triantennary structures were present as trisialo and tetrasialo forms without fucose; the tetrasialo forms were shown to contain a sequence of Neu5Ac alpha 2-3Gal beta 1-3[Neu5Ac alpha 2-6]GlcNAc beta 1- on one of the branches. The biantennary structures were present as completely sialylated nonfucosylated species and as asialo-, agalacto-, and partially fucosylated structures.
Split-mode unstable resonator (1977)

A novel class of unstable resonators is described in which the mode spatial distribution is altered within the resonator by a prism or axicon. In the particular configuration studied in this work, the resonator beam is separated into two halves by an intracavity reflecting prism. The conditions under which the two halves of the resonator become phase locked to form a coherent mode are studied experimentally and discussed in terms of laser injection locking.
Perceptual quality-complexity optimized video playback on handheld devices (2010)

With growing popularity and richer functionality of handheld devices such as PDAs and smart phones, users can enjoy a variety of videos in almost anyplace and anytime. However, since the battery-consumed devices are constrained by limited resources, decoding of full scale video in terms of the frame size and rate is not efficient for handheld devices. This paper presents a low complexity and perceptual quality optimized video playback algorithm. In the proposed method, the best combination of the frame size and rate is determined to maximize the user perceived quality subject to given complexity constraint. According to the selected frame size and rate, the proposed H.264 decoder performs the spatio-temporal rescaling during video playback. Experimental results show that the proposed method reduces the computational complexity significantly while maintaining the acceptable video quality for video playback on handheld devices.
Insulin-like Growth Factor-1 Inhibits Cell Death Induced by Anticancer Drugs in the MCF-7 Cells: Involvement of Growth Factors in Drug Resistance (1995)

The involvement of growth factors in cell survival in the presence of anticancer drugs was investigated. Cell death was induced in the human breast cancer cell line MCF-7, by the structurally and mechanistically unrelated chemotherapeutic drugs puromycin, actinomycin D, 5-fluorouracil, cisplatin, and adriamycin. The effect of insulin-like growth factor-1 (IGF-1), epidermal growth factor (EGF), and insulin on cell death was evaluated by two different methods: (1) trypan blue dye exclusion test and (2) lactic dehydrogenase release into the culture medium. IGF-1 inhibited cell death induced by each of the diverse drugs in a concentration-dependent manner reaching a maximal effect at 40 ng/ml. Insulin mimicked the effect of IGF-1 only at supraphysiological concentration with an optimal effect at 10,000 ng/ml. EGF had no effect on cell death up to 100 ng/ml. Our finding that IGF-1 specifically enhanced MCF-7 cell survival in the presence of different anticancer drugs suggests the involvement of growth factors in the mechanism of drug resistance.

Diffusion of 18 elements implanted into thermally grown SiO2 (2003)

Diffusion data are presented for 18 elements implanted in SiO2 layers thermally grown on silicon and annealed at temperatures ranging from 300 to 1000 °C. Most species studied, (e.g., Be, B, Al, Sc, Ti, V, Zn, Ga, and Mo), showed negligible diffusion over the examined temperature range. In general, this study has shown that the diffusivity of dopants or impurities in SiO2 is significantly smaller than that in silicon. However we also observed that several elements (e.g., Rb and In) have a higher diffusivity in SiO2 than in Si. Because Ga and In are both used as sources for focused ion beam analyses, the lack of Ga diffusion and the movement of In in SiO2 is of interest.
