One memory access bloom filters and their generalization (2011)

The Bloom filters have been extensively applied in many network functions. Their performance is judged by three criteria: processing overhead, space overhead, and false positive ratio. Due to wide applicability, any improvement to the performance of Bloom filters can potentially have broad impact in many areas of networking research. In this paper, we propose Bloom-1, a new data structure that performs membership check in one memory access, which compares favorably with the k memory accesses of a classical Bloom filter. We also generalize Bloom-1 to Bloom-g, allowing performance tradeoff between membership query overhead and false positive ratio. We thoroughly examine the variants in this new family of filters, and show that they can be configured to outperform the Bloom filters with a smaller number of memory accesses, a smaller or equal number of hash bits, and a smaller and comparable false positive ratio in practical scenarios. We also perform experiments based on a real traffic trace to support our new filter design.
IP multicast operational network management: design, challenges, and experiences (2003)

Multicast is a natural enabler for carrying high-bandwidth multimedia broadcasts and seminars on IP networks. Despite the increased need for IP multicast, its commercial deployment has not been widespread. The lack of appropriate network management tools for IP multicast has proven to be a major barrier to its deployment. In this paper we survey the currently available multicast management tools and discuss why they are insufficient. We describe the requirements of an operational multicast management platform and present mmon, a multicast network management system we have built, aimed primarily for use by engineering and operations personnel. Mmon has been tried by over 200 sites and is currently used at HP to manage the multicast network. We discuss some of the challenges and our experiences with designing, implementing, and deploying the system.
Fracturing With Viscoelastic Surfactant Fluid in Cyclic Steam Injection Wells - A Synergy for Heavy Oil Recovery (2012)

Abstract Unconventional oil sources have became one of the most important keys for maintaining the world energy supply. Considering the increasing contribution of the crude below 15 deg. API in the worldwide oil reserves, one aim should be technology development to improve oil production and increase reserves recovery from such reservoirs. One of the most used technologies in hydrocarbon recovery is hydraulic fracturing. On the other hand, cyclic steam injection is a widely used technique to improve recovery from heavy oil reservoirs. This paper describes an example where hydraulic fracturing using anionic viscoelastic surfactant fluids has been combined with cyclic steam injection to synergistically improve production results in a mature heavy oil field. After several years of performing these treatments, this synergy has led to larger heating coverage and therefore improved viscosity reduction of the crude; higher than 100% regained permeability; creation of a very low-viscosity dispersion of the oil in water; and asphaltene dispersion. Such findings are supported by laboratory testing results and backed by post-treatment production results in the heavy oil reservoir where this fracturing campaign was performed and the results analyzed. The observations in the laboratory, their analysis, and the match with field data demonstrate that combining a properly designed stimulation treatment using anionic viscoelastic surfactant with steam injection have led to significant improvements in the stimulation of this heavy oil reservoir. They also show that such results are applicable to other reservoirs where high-viscosity reservoir fluid is a challenge.

Selective Impairment of Hippocampal Gamma Oscillations in Connexin-36 Knock-Out Mouse<i>In Vivo</i> (2003)

The physiological roles of neuronal gap junctions in the intact brain are not known. The recent generation of the connexin-36 knock-out (Cx36 KO) mouse has offered a unique opportunity to examine this problem. Recent in vitro recordings in Cx36 KO mice suggested that Cx36 gap junction contributes to various oscillatory patterns in the theta (approximately 5-10 Hz) and gamma (approximately 30-80 Hz) frequency ranges and affects certain aspects of high-frequency (>100 Hz) patterns. However, the relevance of these pharmacologically induced patterns to the intact brain is not known. We recorded field potentials and unit activity in the CA1 stratum pyramidale of the hippocampus in the behaving wild-type (WT) and Cx36 KO mice. Fast-field "ripple" oscillations (140-200 Hz) were present in both WT and KO mice and did not differ significantly in power, intraepisode frequency, or probability of occurrence. Thus, fast-field oscillations either may not require electrical synapses or may be mediated by a hitherto unknown class of gap junctions. Theta oscillations, recorded during either wheel running or rapid eye movement sleep, were not different either. However, the power in the gamma frequency band and the magnitude of theta-phase modulation of gamma power were significantly decreased in KO mice compared with WT controls during wheel running. This suggests that Cx36 interneuronal gap junctions selectively contribute to gamma oscillations.
Tear Down What Wall? Undefined Borders and the Assertion of Soviet Space in Greater Siberia, 1917-1935 (2015)

Militarization in the Soviet Far East in the 1930s-part and parcel of its Stalinist transformation into a garrison province qua prison-was driven by external events in Northeast Asia. Japanese economic and military expansion, specifically the investiture of Manchuria in 1931, precipitated a crash reversal of the New Economic Policy (NEP) paradigm in the Far East that until then had governed border policies. Hitherto unknown Politbiuro-level plans show that Stalin and his planners deliberately sought long-term qualitative superiority (modern, mechanized forces) to counter quantitative inferiority. The paper gives details of the ultra-secret, seminal orders: massive troop and equipment relocations (by the end of 1932, one ninth of the Red Army was east of Lake Baikal); crash construction of fortifications; etc. However, it goes further. It investigates the extent to which industrial and infrastructure development in the Far East were driven by military considerations, and relied on Gulag labor for completion. By 1934, roughly 60% of the Union-level capital investment in the region had direct or secondary military significance. This is far higher than generally recognized. Since all this had ripple effects throughout the entire USSR, it challenges the Sovietological consensus that threats from the West (especially Nazi Germany) were what prompted the Stalinist militarization drive.
Network Time Protocol Version 4: Protocol and Algorithms Specification (2010)

The Network Time Protocol (NTP) is widely used to synchronize computer
clocks in the Internet. This document describes NTP version 4 (NTPv4),
which is backwards compatible with NTP version 3 (NTPv3), described in
RFC 1305, as well as previous versions of the protocol. NTPv4 includes
a modified protocol header to accommodate the Internet Protocol
version 6 address family. NTPv4 includes fundamental improvements in
the mitigation and discipline algorithms that extend the potential
accuracy to the tens of microseconds with modern workstations and fast
LANs. It includes a dynamic server discovery scheme, so that in many
cases, specific server configuration is not required. It corrects
certain errors in the NTPv3 design and implementation and includes an
optional extension mechanism. [STANDARDS-TRACK]
Upregulation of α7 Nicotinic Receptors by Acetylcholinesterase C-Terminal Peptides (2009)

The alpha-7 nicotinic acetylcholine receptor (a7-nAChR) is well known as a potent calcium ionophore that, in the brain, has been implicated in excitotoxicity and hence in the underlying mechanisms of neurodegenerative disorders such as Alzheimer's disease. Previous research implied that the activity of this receptor may be modified by exposure to a peptide fragment derived from the C-terminal region of the enzyme acetylcholinesterase. This investigation was undertaken to determine if the functional changes observed could be attributed to peptide binding interaction with the a7-nAChR, or peptide modulation of receptor expression.

Greedy Randomized Adaptive Search Procedures (2006)

GRASP is a multi-start metaheuristic for combinatorial problems, in which each iteration consists basically of two phases: construction and local search. The construction phase builds a feasible solution, whose neighborhood is investigated until a local minimum is found during the local search phase. The best overall solution is kept as the result. In this chapter, we first describe the basic components of GRASP. Successful implementation techniques and parameter tuning strategies are discussed and illustrated by numerical results obtained for different applications. Enhanced or alternative solution construction mechanisms and techniques to speed up the search are also described: Reactive GRASP, cost perturbations, bias functions, memory and learning, local search on partially constructed solutions, hashing, and filtering. We also discuss in detail implementation strategies of memory-based intensification and post-optimization techniques using path-relinking. Hybridizations with other metaheuristics, paral lelization strategies, and applications are also reviewed.
Highly Flexible and Transparent Ag Nanowire Electrode Encapsulated with Ultra-Thin Al2O3: Thermal, Ambient, and Mechanical Stabilities (2017)

There is an increasing demand in the flexible electronics industry for highly robust flexible/transparent conductors that can withstand high temperatures and corrosive environments. In this work, outstanding thermal and ambient stability is demonstrated for a highly transparent Ag nanowire electrode with a low electrical resistivity, by encapsulating it with an ultra-thin Al<sub>2</sub>O<sub>3</sub> film (around 5.3 nm) via low-temperature (100 °C) atomic layer deposition. The Al<sub>2</sub>O<sub>3</sub>-encapsulated Ag nanowire (Al<sub>2</sub>O<sub>3</sub>/Ag) electrodes are stable even after annealing at 380 °C for 100 min and maintain their electrical and optical properties. The Al<sub>2</sub>O<sub>3</sub> encapsulation layer also effectively blocks the permeation of H<sub>2</sub>O molecules and thereby enhances the ambient stability to greater than 1,080 h in an atmosphere with a relative humidity of 85% at 85 °C. Results from the cyclic bending test of up to 500,000 cycles (under an effective strain of 2.5%) confirm that the Al<sub>2</sub>O<sub>3</sub>/Ag nanowire electrode has a superior mechanical reliability to that of the conventional indium tin oxide film electrode. Moreover, the Al<sub>2</sub>O<sub>3</sub> encapsulation significantly improves the mechanical durability of the Ag nanowire electrode, as confirmed by performing wiping tests using isopropyl alcohol.
Medullary carcinoma is associated with expression of intercellular adhesion molecule-1. Implication to its morphology and its clinical behavior. (1994)

The histological hallmarks for the diagnosis of medullary breast cancer are circumscription, syncytial architecture, diffuse inflammatory infiltrate, and highly atypical nuclei. The biological and prognostic implication is a lower propensity to metastasize. We studied 19 medullary carcinomas for expression of the intercellular adhesion molecule-1 and lymphocyte-function-associated antigen-1, Neu differentiation factor, tumor necrosis factor-alpha, and the expression of HER-2/neu, HER-4, and HER-3 receptors. Our study revealed that all of the 19 medullary carcinomas expressed the intercellular adhesion molecule-1 and lymphocyte function associated antigen. Eighteen of 19 cancers expressed Neu differentiation factor and tumor necrosis factor-alpha. All medullary cancers expressed the HER-2/neu receptor, however, in the majority of the cases, the staining was confined to the cytoplasm. Only 4 of 12 cancers expressed HER-4 and none of the eight medullary cancers tested expressed HER-3. By comparison, in a control group of infiltrating ductal carcinomas, expression of intercellular adhesion molecule-1, lymphocyte function associated antigen-1, and Neu differentiation factor was positive in about 25 to 30% of the cases, HER-4 was expressed in 75% and HER-3 in 95% of the cases. Taken together, our observations suggest that the expression of intercellular adhesion molecule-1, lymphocyte function associated antigen, Neu differentiation factor, and tumor necrosis factor-alpha as factors that may affect the special morphology and the biological behavior that characterizes medullary carcinomas.
Practical out-of-band authentication for mobile applications (2013)

Mobile devices create new opportunities and challenges for authentication. On one hand, the readily-available sensors provide new opportunities for authentication credentials, such as biometrics and context of the device. On the other hand, mobile applications rely on network services to create rich functionality that often require protection of their sensitive data. The ability for the mobile application developer to adopt a wide range of authentication protocols and techniques is an intractable challenge for adopting new authentication technologies.
Optimal redundancy removal without fixedpoint computation (2011)

Industrial verification and synthesis tools routinely identify and eliminate redundancies from logic designs. In the former case, redundancy removal yields critical speedups to the overall verification process. In the latter case, redundancy removal constitutes a primary mechanism to optimize the final fabricated circuit. Redundancy identification frameworks often utilize a greatest-fixedpoint iteration, initially postulating a set of candidate redundancies to be conjunctively proved then refining candidates based upon failed proof attempts. Such procedures generally do not yield any soundly-proved redundancies until a fixedpoint is achieved. In this paper, we overcome this drawback by augmenting the fixedpoint procedure with a set of efficient techniques to track dependencies between candidate redundancies. This approach enables the identification of an optimal subset of valid redundancies before the fixedpoint is reached, and may also be used to reduce the number of computations within the fixedpoint procedure. We apply our techniques to enhance k-induction as well as a more general transformation-based verification flow. For induction, we demonstrate up to 75% reduction in runtime and 97% reduction in the number of inductive proofs. For the more general flow, we demonstrate up to 90% reduction in runtime and 80% reduction in the total number of proof obligations.
Contribution of Nonneutralizing Vaccine-Elicited Antibody Activities to Improved Protective Efficacy in Rhesus Macaques Immunized with Tat/Env Compared with Multigenic Vaccines (2009)

Previously, chronic-phase protection against SHIV(89.6P) challenge was significantly greater in macaques primed with replicating adenovirus type 5 host range mutant (Ad5hr) recombinants encoding HIVtat and env and boosted with Tat and Env protein compared with macaques primed with multigenic adenovirus recombinants (HIVtat, HIVenv, SIVgag, SIVnef) and boosted with Tat, Env, and Nef proteins. The greater protection was correlated with Tat- and Env-binding Abs. Because the macaques lacked SHIV(89.6P)-neutralizing activity prechallenge, we investigated whether Ab-dependent cellular cytotoxicity (ADCC) and Ab-dependent cell-mediated viral inhibition (ADCVI) might exert a protective effect. We clearly show that Tat can serve as an ADCC target, although the Tat-specific activity elicited did not correlate with better protection. However, Env-specific ADCC activity was consistently higher in the Tat/Env group, with sustained cell killing postchallenge exhibited at higher levels (p < 0.00001) for a longer duration (p = 0.0002) compared with the multigenic group. ADCVI was similarly higher in the Tat/Env group and significantly correlated with reduced acute-phase viremia at wk 2 and 4 postchallenge (p = 0.046 and 0.011, respectively). Viral-specific IgG and IgA Abs in mucosal secretions were elicited but did not influence the outcome of the i.v. SHIV(89.6P) challenge. The higher ADCC and ADCVI activities seen in the Tat/Env group provide a plausible mechanism responsible for the greater chronic-phase protection. Because Tat is known to enhance cell-mediated immunity to coadministered Ags, further studies should explore its impact on Ab induction so that it may be optimally incorporated into HIV vaccine regimens.
Impaired Function of the Tonoplast-Localized Sucrose Transporter in Rice, <i>OsSUT2</i>, Limits the Transport of Vacuolar Reserve Sucrose and Affects Plant Growth  (2011)

Physiological functions of sucrose (Suc) transporters (SUTs) localized to the tonoplast in higher plants are poorly understood. We here report the isolation and characterization of a mutation in the rice (Oryza sativa) OsSUT2 gene. Expression of OsSUT2-green fluorescent protein in rice revealed that OsSUT2 localizes to the tonoplast. Analysis of the OsSUT2 promoter::β-glucuronidase transgenic rice indicated that this gene is highly expressed in leaf mesophyll cells, emerging lateral roots, pedicels of fertilized spikelets, and cross cell layers of seed coats. Results of Suc transport assays in yeast were consistent with a H(+)-Suc symport mechanism, suggesting that OsSUT2 functions in Suc uptake from the vacuole. The ossut2 mutant exhibited a growth retardation phenotype with a significant reduction in tiller number, plant height, 1,000-grain weight, and root dry weight compared with the controls, the wild type, and complemented transgenic lines. Analysis of primary carbon metabolites revealed that ossut2 accumulated more Suc, glucose, and fructose in the leaves than the controls. Further sugar export analysis of detached leaves indicated that ossut2 had a significantly decreased sugar export ability compared with the controls. These results suggest that OsSUT2 is involved in Suc transport across the tonoplast from the vacuole lumen to the cytosol in rice, playing an essential role in sugar export from the source leaves to sink organs.

Solid rotor induction machines for use in electrically-assisted turbochargers (2006)

The stator leakage reactance has a major influence on the performance of a solid rotor induction machine. It is larger and it is more difficult to define and calculate than in a cage-rotor machine. When the higher leakage reactance is taken into account, the equivalent circuit model gives predictions of sufficient precision for design purposes. The airgap, normally chosen to be quite small, is preferably quite large by general standards. The torque varies as (V/f)3 which makes it difficult to provide a wide range of constant power operation in a variable speed application. Slitting the rotor helps to improve the characteristic for variable-speed duties.
