Improving the Reliability of Warehouse Operations in the 3PL Industry: An Australian 3PL Case Study (2018)

Warehouses play an important value-adding role to provide a competitive edge, support business growth and efficiency throughout their supply chains. This paper explores warehouse operations (i.e. receiving, put away, picking, packing and shipping) and a series of challenges faced in managing warehouse operations in general and the 3PL industry in particular. Especially, the paper analyses the warehouse and logistics operations of an Australian 3PL company. By utilizing a mixed method approach both qualitative and quantitative data was gathered through in-depth interviews, direct observations and warehouse operations records. The collected data were then analyzed using thematic analysis. The data was screened and coded to further develop major themes to identify the problematic areas. This analysis helped to identify issues in operations related to the receiving process, missing, picking and locating items as well as human errors. While multiple approaches could be utilized to improve the operations, there yet remained a major challenge to manage operations within the planned budgetary limits. This research, therefore, provides some solutions/recommendations to improve the case company's warehouse operations through staff empowerment, management process improvement, order dispatch and return process improvement, improvement in record keeping, and recruiting more personnel. These recommendations ensure company's efficiency while balancing its challenges both in operations and budgetary constraints. This study thus provides an evidence to improve the reliability of warehouse operations through systematic process improvement.
ATM Mediates Phosphorylation at Multiple p53 Sites, Including Ser46, in Response to Ionizing Radiation (2002)

The p53 tumor suppressor protein preserves genome integrity by regulating growth arrest and apoptosis in response to DNA damage. In response to ionizing radiation (IR), ATM, the gene product mutated in ataxia telangiectasia, stabilizes and activates p53 through phosphorylation of Ser(15) and (indirectly) Ser(20). Here we show that phosphorylation of p53 on Ser(46), a residue important for p53 apoptotic activity, as well as on Ser(9), in response to IR also is dependent on the ATM protein kinase. IR-induced phosphorylation at Ser(46) was inhibited by wortmannin, a phosphatidylinositol 3-kinase inhibitor, but not PD169316, a p38 MAPK inhibitor. p53 C-terminal acetylation at Lys(320) and Lys(382), which may stabilize p53 and activate sequence-specific DNA binding, required Ser(15) phosphorylation by ATM and was enhanced by phosphorylation at nearby residues including Ser(6), Ser(9), and Thr(18). These observations, together with the proposed role of Ser(46) phosphorylation in mediating apoptosis, suggest that ATM is involved in the initiation of p53-dependent apoptosis after IR in human lymphoblastoid cells.
L' enseignement de la Criminologie: le modèle canadien (1990)

Despite similar severity of ischemia/reperfusion, hibernating myocardium showed significantly less ultrastructural evidence of cell injury compared with normally contracting myocardium. These data indicate that human hibernating myocardium is intrinsically more resistant to ischemia/reperfusion injury.
Nerve Pathology Distinguishes Focal Motor Chronic Inflammatory Demyelinating Polyradiculoneuropathy From Multifocal Motor Neuropathy (2020)

Based on clinical evaluation, electrophysiology, and nerve biopsy pathology, we can divide the conditions into inflammatory demyelinating neuropathy (focal CIDP) versus chronic axonal neuropathy (MMN). The divergent pathological findings provide further evidence that CIDP and MMN are fundamentally different disorders.
Doppler Shift Compensation Schemes in VANETs (2015)

Over the last decade vehicle-to-vehicle (V2V) communication has received a lot of attention as it is a crucial issue in intravehicle communication as well as in Intelligent Transportation System (ITS). In ITS the focus is placed on integration of communication between mobile and fixed infrastructure to execute road safety as well as nonsafety information dissemination. The safety application such as emergence alerts lays emphasis on low-latency packet delivery rate (PDR), whereas multimedia and infotainment call for high data rates at low bit error rate (BER). The nonsafety information includes multimedia streaming for traffic information and infotainment applications such as playing audio content, utilizing navigation for driving, and accessing Internet. A lot of vehicular ad hoc network (VANET) research has focused on specific areas including channel multiplexing, antenna diversity, and Doppler shift compensation schemes in an attempt to optimize BER performance. Despite this effort few surveys have been conducted to highlight the state-of-the-art collection on Doppler shift compensation schemes. Driven by this cause we survey some of the recent research activities in Doppler shift compensation schemes and highlight challenges and solutions as a stock-taking exercise. Moreover, we present open issues to be further investigated in order to address the challenges of Doppler shift in VANETs.
The potential for low petroleum gasoline (1996)

The Energy Policy Act requires the Secretary of Energy to determine the feasibility of producing sufficient replacement fuels to replace at least 30 percent of the projected consumption of motor fuels by light duty vehicles in the year 2010. The Act also requires the Secretary to determine the greenhouse gas implications of the use of replacement fuels. A replacement fuel is a non-petroleum portion of gasoline, including certain alcohols, ethers, and other components. The Oak Ridge National Laboratory Refinery Yield Model has been used to study the cost and refinery impacts for production of {open_quotes}low petroleum{close_quotes} gasolines, which contain replacement fuels. The analysis suggests that high oxygenation is the key to meeting the replacement fuel target, and a major contributor to cost increase is investment in processes to produce and etherify light olefins. High oxygenation can also increase the costs of control of vapor pressure, distillation properties, and pollutant emissions of gasolines. Year-round low petroleum gasoline with near-30 percent non-petroleum components might be produced with cost increases of 23 to 37 cents per gallon of gasoline, and with greenhouse gas emissions changes between a 3 percent increase and a 16 percent decrease. Crude oil reduction, with decreased dependence on foreign sources, is a major objective of the low petroleum gasoline program. For year-round gasoline with near-30 percent non-petroleum components, crude oil use is reduced by 10 to 12 percent, at a cost $48 to $89 per barrel. Depending upon resolution of uncertainties about extrapolation of the Environmental Protection Agency Complex Model for pollutant emissions, availability of raw materials and other issues, costs could be lower or higher.
Ultra-long-distance interaction between spin qubits (2006)

We describe a method for implementing deterministic quantum gates between two spin qubits separated by centimeters. Qubits defined by the singlet and triplet states of two exchange coupled quantum dots have recently been shown to possess long coherence times. When the effective nuclear fields in the two asymmetric quantum dots are different, total spin will no longer be a good quantum number and there will be a large electric dipole coupling between the two qubit states. We show that when such a double-quantum-dot qubit is embedded in a superconducting microstrip cavity, the strong coupling regime of cavity quantum electrodynamics lies within reach. Virtual photons in a common cavity mode could mediate coherent interactions between two distant qubits embedded in the same structure; the range of this two-qubit interaction is determined by the wavelength of the microwave transition.
Serotonin Modulated CA++Dependent K+Channels in Alloimmune Effector Cell Lytic Function (1989)

Potassium channel activity has been implicated in the lytic function of cloned murine effector T lymphocytes (5) and human NK cells (12) as well as in the initiation of the injury process in tumor cells (23). In the present studies, the effects of various K+ channel blockers on the cytolytic function of in vivo derived alloimmune lymphocytes towards P815 tumor cells were evaluated. The classical K+ channel blocker 4-aminopyridine (4-AP), the naturally occurring monoamine serotonin (5-hydroxytryptamine, 5-HT) and its agonist, quipazine, as well as the Ca++ dependent K+ channel blocker quinidine were chosen for investigation based on their known ion channel gating properties. These agents, when present in the assay medium, inhibited in a dose dependent manner the lysis of P815 tumor cells as measured by specific 51Cr release. Preincubation of effector lymphocytes with the various K+ channel blockers resulted in greater inhibition of lysis than did the preincubation of target cells. The 5-HT agonist quipazine was of particular interest in that it inhibited the lytic process with equal effectiveness when continuously present in the assay medium or when the effector cells alone were preincubated. Quinidine was used to investigate whether Ca++ dependent K+ channels were the predominant ion channel involved in the lytic process. When present during the lytic assay, quinidine was similar to quipazine in terms of their dose range at which they inhibited the lytic process. These results indicate that 5-HT sensitive Ca++ dependent K+ channels are likely to be involved in the delivery of lytic signal (s) by immune effector lymphocytes and suggests that neuroenocrine products may modulate the functional activity of in vivo derived lymphocytes.
Development Status of Coal-Fired Gas Heaters for Brayton-Cycle Cogeneration Systems (1983)

Under contract from the Department of Energy, Rocketdyne is developing the technology of coal-fired gas heaters for utilization in Brayton-cycle cogeneration systems. The program encompasses both atmospheric fluidized bed and pulverized coal combustion systems; and it is directed toward the development of gas heater systems capable of delivering high pressure air or helium at 1550 F, when employing metallic heat exchangers, and 1750 F, when employing ceramic heat exchangers. This paper reports on the development status of the program, with discussions of the completed “screening” corrosion/erosion tests of candidate heat exchanger materials, a description and summary of the operating experience with the 6- by 6-foot AFB test facility and a projection of the potential for relatively near term commercialization of such heater systems.
Synthesis and properties of thiadiazole lubricant additives (2017)

Purpose Thiadiazole compounds and their derivatives have carrying capacity and good lubricating properties. However, their poor oil-solubility limited their wide usage in lubricating oil. The study aims to develop thiadiazole lubricant additives with better oil-solubility. When the hindered phenol antioxidation functional group and alkyl-chain are introduced to thiadiazole, the resulting product could have better oil-solubility and excellent antioxidation resistance, anti-wear and corrosion resistance in the lubricating oil. Design/methodology/approach One kind of thiadiazole lubricant additive, for the first time, has been synthesized from 2,5-dimercapto-1,3,4-thiadiazole. Its tribological performance has also been evaluated by four-ball test. And, its oxidation resistance has been estimated by rotating pressure vessel oxidation test and pressurized differential scanning calorimetry. The anticorrosion performance of such an additive has been studied by GB/T 5096 standard method test. Findings The synthesized thiadiazole additive has excellent anti-oxidation capability, good anti-wear and extreme pressure properties and good anticorrosion performance, in comparison with zinc dialkyl dithiophosphate (ZDDP). In base oils, the comprehensive performance of thiadiazole additive is comparable to ZDDP. Mechanistic studies indicate that the S and N active elements were involved in the formation of a boundary film. This may account for the formation of a composite membrane on the metal surface and thus for the tribological performance of such thiadiazole additives. Originality/value The thiadiazole derivatives, which are ashless and have environmentally friendly features, are a potential alternative to ZDDP. Because of the film formed on the friction surface, thiadiazole compounds may serve as an excellent anti-wear additive and are expected to reduce friction and wear between metals.
Long-term response to gluten-free diet as evidence for non-celiac wheat sensitivity in one third of patients with diarrhea-dominant and mixed-type irritable bowel syndrome (2016)

Using strict criteria as recommended for IBS studies, about one third of patients with IBS-D or IBS-M are wheat sensitive, with a similar proportion in both IBS types. Expression of HLA-DQ2/8 is not useful as diagnostic marker for WS. Long-term adherence to a GFD is high and can sustain symptomatic improvement.
Evaluation of a Reduced Precision Redundancy FFT Design (2020)

Fault-tolerant designs for space applications on SRAM-based FPGAs typically require Distributed Triple Modular Redundancy (DTMR) or Block Triple Modular Redundancy (BTMR) to mitigate faults induced by ionizing radiation. These methods lead to a large area overhead, which, in turn, can make the design more susceptible to the radiation effects. The Reduced Precision Redundancy (RPR) technique has been proposed as a trade-off between area overhead and reliability. In this work, the RPR hardening technique is reviewed and compared to TMR by performing fault injection campaigns using a hardened Fast Fourier Transform (FFT) block as a case study. Results show that the implemented RPR not only saves FPGA resources, but also reduces the critical error rate and the impact of Common Mode Failures (CMF) with respect to the TMR solution.
Recent results using a 256 &#x00D7; 256 2-D array transducer for 3-D rectilinear imaging (2008)

In previous work, we presented initial experimental results using a 256 times 256 2-D array with row-column methods. The main benefits of this design are a reduced number of interconnects, a T/R switching scheme with a simple diode circuit, and an ability to perform transmit beamforming in azimuth and receive beamforming in elevation for volumetric imaging of targets near the transducer. In this paper, we present 3-D images of axial wires embedded in a clear gelatin phantom, of an 8 mm diameter cylindrical anechoic cyst phantom and of a 10 mm diameter spherical anechoic cyst phantom acquired from a new 256 times 256 2-D array transducer. DAX processing was used to reduce clutter due to 1-way beamforming.
Fetal monitor for non-stress-test screening at home. (1998)

A fetal monitoring device developed for non-stress-test (NST) screening at home works on battery power, and is so small and lightweight (152 x 120 x 64 mm, 600 g) that a pregnant woman can monitor fetal Doppler ultra-sound and record fetal heart rate (FHR) and uterine contraction (UC) data on an attached memory IC card at any time and in any place away from a hospital. The physician can evaluate these data, transmitted via public telephone lines, using a built-in modem in the monitor. The combination of the memory IC card as a temporary storage device with the intermittent data transmission to the host provides endless data storage. The input-output relationship of the device was quantitatively evaluated using a Doppler ultrasound heart rate simulator. Forty pregnant women participated in an evaluation of this system. The total number of NST data transmissions was 648, and the total amount of data received was more than 6.7 Mbytes. Of the 648 transmissions, 475 were adequate for clinical interpretation. Of the 101 failed NST data transmissions, 85 resulted from patient handling errors. However, 82.4% of these errors resulted in reexamination and transfer of new data by the patients, who were aware of the insufficiency of the original data. The main cause of the noise in the data was zero-count data; this noise rate accounted for 4.1% of the data abnormalities. A questionnaire survey found that 96% of the participants wanted to use the monitor again in their next pregnancies, and 83% would recommend its use to pregnant friends. The system was easily used and accepted by pregnant women, and the NST data obtained were sufficient for clinical interpretation.
Polymer complexes stabilized through hydrogen bonds. Influence of “structure defects” on complex formation: Viscometry and fluorescence polarization measurements (1988)

Abstract The structure of polymer complexes stabilized through hydrogen bonds can be much influenced by the presence of nonactive groups (structure defects) on the polymer chains. In this paper two very simple homopolymer/copolymer systems are studied: the homopolymer is a polybase, polyoxyethylene (PEO) or polyvinylpyrrolidone (PVP), and the copolymer a partially neutralized poly(acrylic acid) (PAA). The acrylate groups on PAA chain behave as structure defects. Viscometry provides information about macroscopic structure of polymer complex in solution while fluorescence polarization is especially adapted for the study of the local mobility of polymer chains. Two kinds of structure are found: the first one is compact and implies a low viscosity of the mixture, eventually precipitation occurs, the second one is a highly branched structure, close to a gel, which leads to a very high increase in viscosity. For instance, the viscosity of the mixture may be several hundred times higher than the sum of the viscosities of the two individual polymer solutions. Such mixtures are especially adapted to be used like thickening agents.
Reservoir response to tidal and barometric effects (1980)

For the first time, the structure-activity relationships of thirteen synthesized flavonoids have been investigated by evaluating their ability to modulate horseradish peroxidase (HRP) catalytic activity. Indeed, a modified spectrophotometrically method was carried out and optimized using 4-methylcatechol (4-MC) as peroxidase co-substrate. The results show that these flavonoids exhibit a great capacity to inhibit peroxidase with Ki values ranged from 0.14±0.01 to 65±0.04mM. Molecular docking has been achieved using Auto Dock Vina program to discuss the nature of interactions and the mechanism of inhibition. According to the docking results, all the flavonoids have shown great binding affinity to peroxidase. These molecular modeling studies suggested that pyran-4-one cycle acts as an inhibition key for peroxidase. Therefore, potent peroxidase inhibitors are flavonoids with these structural requirements: the presence of the hydroxyl (OH) group in 7, 5 and 4' positions and the absence of the methoxy (O-CH<sub>3</sub>) group. Apigenin contributed better in HRP inhibitory activity. The present study has shown that the studied flavonoids could be promising HRP inhibitors, which can help in developing new molecules to control thyroid diseases.
Kalman filter based on error state variables in SINS + GPS navigation application (2011)

Kalman filter (KF) is widely used in SINS + GPS-guided combination method, but the sensor's mathematical model of the transporter is generally nonlinear, so the complexity and computation of the model are large. In this paper, we present an Kalman filter algorithm based on error state variables in SINS + GPS navigation application. The mathematical model of the errors of GPS data and inertial navigation data is linear, so the errors are taken as the states, which avoids the complexity caused by nonlinear and makes the design difficulty reduced significantly. This paper also gives the design process and the mathematical model of navigation system, and sets the state parameters of the model. Finally, simulation results show the effectiveness of the algorithm.

Nonlinear spectroscopy near half-gap in bulk and quantum well GaAs/AlGaAs waveguides (1992)

We study the nonlinear properties of bulk AlGaAs and GaAs/AlGaAs multiple quantum wells (MQW) below the half-band-gap energy using subpicosecond pulses between 1.65 and 1.7 μm. In the bulk material we find a value for the nonlinear index n2 = +3.6× 10−14 cm2/W and a two-photon absorption coefficient β = 0.26 × 10−4 cm/MW. In the MQW we measure an n2 up to 2.4 times larger, and we attribute this enhancement to a stronger 1S-exciton intermediate state. The β value is up to 25 times larger in the MQW. This larger value may result from midgap states that resonantly enhance the virtual intermediate state in two-photon absorption and act as a real transition in a two-step absorption process. The resulting figure of merit (2n2/βλ) for the bulk (MQW) material is 17 (1.6), which means that these semiconductors below half band gap are appropriate for all-optical switching and quantum optics applications. We confirm that n2 is instantaneous on the 300 fs time scale of our pulses from self-phase-modulation spectra as well as time-resolved pump-probe measurements. However, we find an intriguing exchange of energy between the two orthogonal axes as evidenced by the signal along the probe axis following the negative derivative of the pump intensity. This result may be explained by self-phase modulation of the pump combined with a low-frequency Raman process that couples the modes along orthogonal axes.
<title>Imaging through optically opaque barriers with microwaves and millimeter waves</title> (1998)

A rudimentary, inexpensive microwave and millimeter wave imaging system has been developed for imaging scenes viewed through optically opaque barriers. We have quantified the attenuation of microwave-band and millimeter-band radiation in materials commonly used in construction. We have also investigated, on a fundamental level, the imaging of the content of a briefcase using this simple scanner.
