A Coordinated Approach for Practical OS-Level Cache Management in Multi-core Real-Time Systems (2013)

Many modern multi-core processors sport a large shared cache with the primary goal of enhancing the statistic performance of computing workloads. However, due to resulting cache interference among tasks, the uncontrolled use of such a shared cache can significantly hamper the predictability and analyzability of multi-core real-time systems. Software cache partitioning has been considered as an attractive approach to address this issue because it does not require any hardware support beyond that available on many modern processors. However, the state-of-the-art software cache partitioning techniques face two challenges: (1) the memory co-partitioning problem, which results in page swapping or waste of memory, and (2) the availability of a limited number of cache partitions, which causes degraded performance. These are major impediments to the practical adoption of software cache partitioning. In this paper, we propose a practical OS-level cache management scheme for multi-core real-time systems. Our scheme provides predictable cache performance, addresses the aforementioned problems of existing software cache partitioning, and efficiently allocates cache partitions to schedule a given task set. We have implemented and evaluated our scheme in Linux/RK running on the Intel Core i7 quad-core processor. Experimental results indicate that, compared to the traditional approaches, our scheme is up to 39% more memory space efficient and consumes up to 25% less cache partitions while maintaining cache predictability. Our scheme also yields a significant utilization benefit that increases with the number of tasks.
Quantum Process Estimation via Generic Two-Body Correlations (2009)

Performance of quantum process estimation is naturally limited to fundamental, random, and systematic imperfections in preparations and measurements. These imperfections may lead to considerable errors in the process reconstruction due to the fact that standard data analysis techniques presume ideal devices. Here, by utilizing generic auxiliary quantum or classical correlations, we provide a framework for estimation of quantum dynamics via a single measurement apparatus. By construction, this approach can be applied to quantum tomography schemes with calibrated faulty state generators and analyzers. Specifically, we present a generalization of "Direct Characterization of Quantum Dynamics" [M. Mohseni and D. A. Lidar, Phys. Rev. Lett. 97, 170501 (2006)] with an imperfect Bell-state analyzer. We demonstrate that, for several physically relevant noisy preparations and measurements, only classical correlations and small data processing overhead are sufficient to accomplish the full system identification. Furthermore, we provide the optimal input states for which the error amplification due to inversion on the measurement data is minimal.
Direct Longitudinal Computed Tomography of the Forearm (1981)

A method is outlined for obtaining direct longitudinal computed tomograms of the forearm using a conventional total body scanner. A case is described in which longitudinal scanning helped define a soft tissue tumor of the forearm and thereby assisted in surgical planning.
Cloning of nisin resistance determinant and replication origin on 7.6-kilobase EcoRI fragment of pNP40 from Streptococcus lactis subsp. diacetylactis DRC3 (1988)

The nisin resistance determinant and an origin of replication on pNP40, a plasmid of about 60 kilobases that is present in Streptococcus lactis subsp. diacetylactis DRC3, was cloned on a 7.6-kilobase EcoRI fragment. When self-ligated, this fragment existed as an independent replicon (pFM011) and contained a 2.6-kilobase EcoRI-XbaI fragment encoding nisin resistance.
Isolation of acetyl esterase mutants of Bacillus subtilis 168 (1977)

Five mutants of Bacillus subtilis 168 defective in an intracellular esterase activity were identified. By polyacrylamide gel electrophoresis, four of the mutants were shown to lack esterase B activity, and the fifth lacked esterase A activity. All of the back-crossed esterase mutants were able to sporulate at wild-type frequency and produce exoprotease(s) and antibiotic(s). No difference in motility could be attributed to the esterase mutation. PBS1 transduction analysis showed all the esterase B mutations to be linked to the hisA marker.
RADIOCHEMICAL SEPARATION OF CARRIER-FREE ZIRCONIUM FROM YTTRIUM OXIDE (1965)

Complete tumor resection with preservation or improvement of visual function is the goal of tuberculum sellae meningioma (TSM) treatment. The authors retrospectively reviewed 51 patients treated surgically for TSM between 2003 and 2010, with special attention to surgical technique, visual outcomes, and prognostic factors for treatment outcome. All patients were operated via the lateral subfrontal approach. The cohort mean age and Karnofsky performance status (KPS) on admission was 57.1 ± 13.6 and 84.3 ± 11.7, respectively. The most common presenting sign was visual impairment. The mean tumor size was 29.4 ± 10.7 mm. In 45 of the patients (88.2%), gross total resection was achieved. Improvement and/or preservation of visual acuity and visual field were achieved in 95.9% and 85.3%, respectively. Visual functions on admission were found to be the strongest predictors for postoperative improvement in visual outcome, followed by better KPS on admission, smaller tumor size, and young age. Postoperative neurological complications included cerebrospinal fluid (CSF) leak, meningitis, and postoperative seizures. TSM can be safely operated on through the lateral subfrontal approach. A high percentage of complete tumor resection and excellent visual outcomes are achieved using this technique. Surgical treatment in the early stage of the disease may result in a better visual outcome.
Detection of Squarene Hydroperoxide (1993)

Squalene hydroperoxide present in human skin surface lipids was examined by a chemiluminescence high performance liquid chromatography (CL-HPLC) system. A mixture of cytochrome c and luminol served as the hydroperoxide-specific luminescence reagent for post-column detection in reversed phase HPLC. Squalene hydroperoxide was previously detected in skin surface lipids of the human forehead following exposure to the sun. Therefore, in this study, squalene monohydroperoxide was prepared by dye-sensitized photooxidation and its chemical structure was determined by 1H-NMR, 13C-NMR, and FAB-MS. The detection limit of squalene monohydroperoxide in CL-HPLC system was as low as 1 pmol. Skin surface lipids from forehead, scalp, and dandruff were also studied. By exposure to sun light or after washing with shampoo, squalene monohydroperoxide could be detected in nearly all samples examined. Squalene may thus be considered the first target lipid on human skin surface that incurs oxidative stress by sun light exposure, etc.
[Progressive sensorineural hearing loss: metabolic, hormonal and vascular etiology]. (1998)

Metabolic, hormonal and vascular disorders are considered to cause hearing dysfunction such as progressive sensorineural hearing loss (PSNHL). The diseases most commonly associated with PSNHL are diabetes mellitus, congenital and acquired hypothyroidism, chronic renal failure, chronic labyrinthine ischemia determined by non-hematologic factors (tissue perfusion pressure, blood vessel diameter) or by hematologic factors (blood viscosity and/or rigidity of the red blood cells). In this study a review of data on the relationship between these clinical disorders and the presence and deterioration of the hearing function was carried out. PSNHL seems to be significantly associated with diabetes mellitus, in particular the mitochondrial type: a progressive deterioration of the hearing function is reported in 60% of the patients suffering from this type of disease with mitochondrial mutations. Regarding hypothyroid disorders, the data do not support a pathogenetic link between PSNHL and acquired hypothyroidism, whereas in subjects with congenital hypothyroidism both clinical and experimental results indicate a progressive damage of hearing function if the thyroid disorder is not treated early in life. Also, in patients with chronic renal failure the hearing thresholds seem to be significantly worse than in control subjects, particularly in patients undergoing dialysis, whereas the effect of kidney transplantation on auditory function is still not understood. Finally a relationship between PSNHL and chronic labyrinthine ischemia due to alterations of hematologic factors (increase of blood viscosity and/or increase of rigidity of the red blood cells) has been reported by several authors. However, data on high blood pressure and hyperlipoproteinemia as causes of deterioration of hearing acuity are controversial, and it is often difficult to understand whether the progressive hearing deficit is due only to these factors or also to the elderly age of patients.
Low-temperature heat capacity and localized vibrational modes in natural and synthetic tetrahedrites (2014)

The heat capacity of natural (Cu12−x (Fe, Zn, Ag)x(Sb, As)4S13) and synthetic (Cu12−xZnxSb4S13 with x = 0, 1, 2) tetrahedrite compounds was measured between 2 K and 380 K. It was found that the temperature dependence of the heat capacity can be described using a Debye term and three Einstein oscillators with characteristic temperatures that correspond to energies of ∼1.0 meV, ∼2.8 meV, and ∼8.4 meV. The existence of localized vibrational modes, which are assigned to the displacements of the trigonally coordinated Cu atoms in the structure, is discussed in the context of anharmonicity and its effect on the low lattice thermal conductivity exhibited by these compounds.
Optimizing Ischemia/Reperfusion in the Failing Rat Heart—Improved Myocardial Protection With Acute ACE Inhibition (2002)

Acute ACE inhibition during CP improves postischemic systolic and diastolic function, coronary perfusion as well as HEP-levels in a rat model of HF. These results may have clinical impact on patients with HF undergoing cardiac surgery.
<title>Very low cost real time histogram-based contrast enhancer utilizing fixed-point DSP processing</title> (1998)

A real time contrast enhancement system utilizing histogram- based algorithms has been developed to operate on standard composite video signals. This low-cost DSP based system is designed with fixed-point algorithms and an off-chip look up table (LUT) to reduce the cost considerably over other contemporary approaches. This paper describes several real- time contrast enhancing systems advanced at the Sarnoff Corporation for high-speed visible and infrared cameras. The fixed-point enhancer was derived from these high performance cameras. The enhancer digitizes analog video and spatially subsamples the stream to qualify the scene's luminance. Simultaneously, the video is streamed through a LUT that has been programmed with the previous calculation. Reducing division operations by subsampling reduces calculation- cycles and also allows the processor to be used with cameras of nominal resolutions. All values are written to the LUT during blanking so no frames are lost. The enhancer measures 13 cm X 6.4 cm X 3.2 cm, operates off 9 VAC and consumes 12 W. This processor is small and inexpensive enough to be mounted with field deployed security cameras and can be used for surveillance, video forensics and real- time medical imaging.
Aberrant Innate Immune Activation following Tissue Injury Impairs Pancreatic Regeneration (2014)

Normal tissue architecture is disrupted following injury, as resident tissue cells become damaged and immune cells are recruited to the site of injury. While injury and inflammation are critical to tissue remodeling, the inability to resolve this response can lead to the destructive complications of chronic inflammation. In the pancreas, acinar cells of the exocrine compartment respond to injury by transiently adopting characteristics of progenitor cells present during embryonic development. This process of de-differentiation creates a window where a mature and stable cell gains flexibility and is potentially permissive to changes in cellular fate. How de-differentiation can turn an acinar cell into another cell type (such as a pancreatic β-cell), or a cell with cancerous potential (as in cases of deregulated Kras activity) is of interest to both the regenerative medicine and cancer communities. While it is known that inflammation and acinar de-differentiation increase following pancreatic injury, it remains unclear which immune cells are involved in this process. We used a combination of genetically modified mice, immunological blockade and cellular characterization to identify the immune cells that impact pancreatic regeneration in an in vivo model of pancreatitis. We identified the innate inflammatory response of macrophages and neutrophils as regulators of pancreatic regeneration. Under normal conditions, mild innate inflammation prompts a transient de-differentiation of acinar cells that readily dissipates to allow normal regeneration. However, non-resolving inflammation developed when elevated pancreatic levels of neutrophils producing interferon-γ increased iNOS levels and the pro-inflammatory response of macrophages. Pancreatic injury improved following in vivo macrophage depletion, iNOS inhibition as well as suppression of iNOS levels in macrophages via interferon-γ blockade, supporting the impairment in regeneration and the development of chronic inflammation arises from aberrant activation of the innate inflammatory response. Collectively these studies identify targetable inflammatory factors that can be used to influence the development of non-resolving inflammation and pancreatic regeneration following injury.
Optimum Photoluminescence Excitation and Recharging Cycle of Single Nitrogen-Vacancy Centers in Ultrapure Diamond (2012)

Important features in the spectral and temporal photoluminescence excitation of single nitrogen-vacancy (NV) centers in diamond are reported at conditions relevant for quantum applications. Bidirectional switching occurs between the neutral (NV(0)) and negatively charged (NV(-)) states. Luminescence of NV(-) is most efficiently triggered at a wavelength of 575 nm which ensures optimum excitation and recharging of NV(0). The dark state of NV(-) is identified as NV(0). A narrow resonance is observed in the excitation spectra at 521 nm, which mediates efficient conversion to NV(0).
Hyperbaric Oxygenation Accelerates the Healing Rate of Nonischemic Chronic Diabetic Foot Ulcers (2003)

In addition to standard multidisciplinary management, HBO doubles the mean healing rate of nonischemic chronic foot ulcers in selected diabetic patients. The time dependence of the effect of HBO warrants further investigations.
Distributed simulation test bed for intelligent transportation systems design and analysis (2004)

There has been increasing interest in the exploitation of advances in information technology (e.g., mobile computing and wireless communications) in surface transportation systems. Classes of applications that could benefit from such an infrastructure include:• Driver assistance and safety applications: Traffic information or hazardous road conditions may be disseminated to avoid congestion and improve safety.• Commercial applications: Information systems of roadside businesses (hotels, restaurants, gas stations, etc.) can be made accessible to travelers to disseminate up-to-date information (e.g., availability, pricing), or provide services (e.g., reservations, Internet access) to travelers.• Entertainment applications: Passengers may be able to communicate with other, nearby travelers.
Remanufacturing Industry for Automobile Parts of USA (2010)

Remanufacturing is a process that restores old products to perform like new, while saving energy, reducing consumption of natural resources, and lowering environmental emissions. By extending the product life cycle, remanufacturing approaches enable closed loop material cycles that are ultimately necessary for a sustainable society. This paper provides some description of the current automotive remanufacturing enterprise, with a particular emphasis on key vehicle components that are currently remanufactured. The analysis yields two major conclusions. First, volume of the USA automotive after sales and remanufacturing industry market is estimated. Second, market price of a remanufactured component in the automotive sector is surprisingly uncorrelated with the number of companies engaged in remanufacturing that component - at least for companies registered with the Automotive Parts Remanufacturing Association (ARPA).

Uncertainty Can Increase Explanatory Credibility (2013)

In daily conversations, what information do people use to assess their conversational partner’s explanations? We explore how a metacognitive cue, in particular the partner’s confidence or uncertainty, can modulate the credibility of an explanation. Two experiments showed that explanations are accepted more often when delivered by an uncertain conversational partner. Participants in Experiment 1 demonstrated the general effect by interacting with a pseudoautonomous robotic confederate. Experiment 2 used the same methodology to show that the effect was applicable to explanatory reasoning and not other sorts of inferences. Results are consistent with an account in which reasoners use relative confidence as a metacognitive cue to infer their conversational partner’s depth of processing.
Pulse trapping resulting from different polarized angles in birefringent photonic crystal fibers (2005)

We present a theoretical investigation of the nonlinear propagation of an optical pulse in a birefringent photonic crystal fiber (PCF). The strict coupled nonlinear Schroednger equations are solved numerically using a standard split-step Fourier algorithm. The phenomenon of pulse trapping is observed for different polarized angles except 0 degree and 90 degree, when the central wavelength of the input optical pulse is located in the anomalous dispersion region. With a single pulse which inclines from one axis launched into a birefringent PCF, the input pulse is split into two orthogonally components (signal and pump component) between the two orthogonally axes. The signal pulse suffers cross phase modulation by the pump (Raman shifted soliton) pulse and it is trapped and copropagates with the Raman soliton pulse along the fiber. A minimum trapping efficiency is obtained when the polarized angle is at 45<sup>o</sup>. For two complementary polarized angles, higher trapping efficiency can be obtained for smaller angle. As the input power of pulse is increased, the red-shift of the Raman soliton is considerably enhanced, leading to further red-shift of the trapped pulse to satisfy the condition of group velocity matching.
Indirect sliding mode control of a three-phase active power filter (2002)

The objective of this paper is to compensate the harmonic pollution due to power electronic converters by using the sliding mode control. In this way, a control scheme based on a new switching selection table is proposed. This method is able to reduce the sensitivity of the compensator to variations in system parameters which results in an improvement in the system's robustness. In the paper, comparative simulations are carried out to show the validity of the proposed method.
Effect of shock compression on wurtzite-type ZnMgS crystals (2011)

It is hard to generate twin defects in wurtzite-type ZnMS (M: metal element) crystals by static mechanical method, while it is important for the luminescence. It was found that many twin defects were formed in wurtzite-type ZnMgS crystals by shock compression of &gt;15 GPa in stress, and the absorption and luminescence spectra changed.
Preparation of Yb-Ba-Cu-O Superconducting Films Using an Arc Discharge Evaporation Method (1989)

We report a new process for preparing superconducting films of YbBa 2 Cu 3 O 7- x using DC arc discharge evaporation on insulating substrates such as SrTiO 3 (100) and MgO(100). The films were deposited without intentional heating and subsequently annealed typically at 950°C for 2 hours in O 2 atmosphere. Although the as-deposited films were amorphous and insulators, the annealed ones on MgO substrates showed superconductivity with Tcend(zero resistivity)=78 K. However, the films on other substrates (Y-stabilized ZrO 2 , SrTiO 3 , and Al 2 O 3 ) did not show superconductivity down to 30 K. It was found from X-ray diffraction analysis that the films on MgO were predominantly oriented with the c -axis perpendicular to the substrate.

Studies on Mineralocorticoid ‘Escape’ in Cirrhosis (1979)

1. The mineralocorticoid 9 alpha-fluorohydrocortisone was given to 12 patients with cirrhosis without ascites. In seven an 'escape' from its sodium-retaining effects was observed, the other five continuing to retain sodium. 2. Changes in plasma renin activity (PRA) and inulin clearance (Cinulin) were used in the assessment of possible changes in the 'effective' extracellular fluid volume. PRA fell and Cinulin increased to a similar extent in each of the two groups of patients. The findings do not support the concept that the failure to show the mineralocorticoid escape in some patients with cirrhosis is due to a failure of expansion of the effective extracellular fluid volume. 3. Sodium reabsorption in the different segments of the nephron as estimated by clearance techniques under conditions of maximal water diuresis showed that the greatest changes to account for both mineralocorticoid escape and sodium retention were in the part of the nephron beyond the diluting segment.
