Strategic Monitoring and Alignment to Achieve Business Process Best Practices (2006)

Business process design, reengineering and monitoring enable companies to achieve market-wide competitiveness and reduce their reaction time to environmental changes. IT systems become more sophisticated to meet the demands for real-time performance measurement and management. Besides, strategic management approaches such as the balanced scorecard gain more and more importance due to lacking alignment and strategic orientation in companies. Holistic management systems are therefore emerging. This paper focuses on a strategic management and monitoring framework that incorporates holistic aspects from the balanced scorecard with demands to data- and business driven process design and controlling. As a result, not a specific monitoring application is presented, but a methodology to combine strategic and tactical monitoring under best-practice assumptions.
Triple Structural Transition below Room Temperature in the Antifilarial Drug Diethylcarbamazine Citrate (2010)

A very unusual triple structural transition pattern below room temperature was observed for the antifilarial drug diethylcarbamazine citrate. Besides the first thermal, crystallographic, and vibrational investigations of this first-line drug used in clinical treatment for lymphatic filariasis, a noteworthy behavior with three structural transformations as a function of temperature was demonstrated by differential scanning calorimetry, Raman spectroscopy, and single-crystal X-ray diffractometry. Our X-ray data on single crystals allow for a complete featuring and understanding of all transitions, since the four structures associated with the three solid−solid phase transformations were accurately determined. Two of three structural transitions show an order−disorder mechanism and temperature hysteresis with exothermic peaks at 224 K (T1′) and 213 K (T2′) upon cooling and endothermic ones at 248 K (T1) and 226 K (T2) upon heating. The other transition occurs at 108 K (T3) and it is temperature-rate sensitive. Molecular displacements onto the (010) plane and conformational changes of the diethylcarbamazine backbone as a consequence of the C−H···N hydrogen bonding formation/cleavage between drug molecules explain the mechanism of the transitions at T1′/T2. However, such changes are observed only on alternate columns of the drug intercalated by citrate chains, which leads to a doubling of the lattice period along the a axis of the 235 K structure with respect to the 150 and 293 K structures. At T2′/T1, these structural alterations occur in all columns of the drug. At T3, there is a rotation on the axis of the N−C bond between the carbamoyl moiety and an ethyl group of one crystallographically independent diethylcarbamazine molecule besides molecular shifts and other conformational alterations. The impact of this study is based on the fascinating finding in which the versatile capability of structural adaptation dependent on the thermal history was observed for a relatively simple organic salt, diethylcarbamazine citrate.
Bayesian deconvolution of noisy filtered point processes (2001)

The detection and estimation of filtered point processes using noisy data is an essential requirement in many seismic, ultrasonic, and nuclear applications. We address this joint detection/estimation problem using a Bayesian approach, which allows us to easily include any relevant prior information. Performing Bayesian inference for such a complex model is a challenging computational problem as it requires the evaluation of intricate high-dimensional integrals. We develop here an efficient stochastic procedure based on a reversible jump Markov chain Monte Carlo method to solve this problem and prove the geometric convergence of the algorithm. The proposed model and algorithm are demonstrated on an application arising in nuclear science.
Isolation and characterization of a 2.2‐kb operon preceding the α‐amylase gene of Bacillus amyloliquefaciens (1986)

A DNA region of 2.8 X 10(3) base pairs (2.8 kb) upstream of the Bacillus amyloliquefaciens alpha-amylase gene has been isolated. This DNA gave rise to a 2.2-kb transcript. The 3' end of the transcript was mapped with S1 nuclease and shown to terminate 49 base pairs upstream of the -35 region of the alpha-amylase promoter. In B. subtilis minicells this 2.2-kb transcript coded for three different polypeptides, thus indicating a polycistronic operon-type structure. The location and the order of the polypeptides were established using DNA deletions. The joining of the 2.2-kb operon to the downstream alpha-amylase gene in the plasmid pUB110 did not have any significant effect on the level of expression of the alpha-amylase.
A tapered dielectric waveguide solar concentrator for a compound semiconductor photovoltaic cell (2010)

A novel tapered dielectric waveguide solar concentrator is proposed for compound semiconductor solar cells utilizing optical fiber preform. Its light collecting capability is numerically simulated and experimentally demonstrated for feasibility and potential assessments. Utilizing tapered shape of an optical fiber preform with a step-index profile, low loss guidance was enhanced and the limitation in the acceptance angle of solar radiation was alleviated by an order of magnitude. Using a solar simulator the device performances were experimentally investigated and discussed in terms of the photocurrent improvements. Total acceptance angle exceeding +/- 6 degrees was experimentally achieved sustaining a high solar flux.
Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry for the Discrimination of Food-Borne Microorganisms (2006)

A methodology based on matrix-assisted laser desorption ionization-time of flight mass spectrometry of intact bacterial cells was used for rapid discrimination of 24 bacterial species, and detailed analyses to identify Escherichia coli O157:H7 were carried out. Highly specific mass spectrometric profiles of pathogenic and nonpathogenic bacteria that are well-known major food contaminants were obtained, uploaded in a specific database, and made available on the Web. In order to standardize the analytical protocol, several experimental, sample preparation, and mass spectrometry parameters that can affect the reproducibility and accuracy of data were evaluated. Our results confirm the conclusion that this strategy is a powerful tool for rapid and accurate identification of bacterial species and that mass spectrometric methodologies could play an essential role in polyphasic approaches to the identification of pathogenic bacteria.

Dissociative attachment and surface reactions induced by low-energy electrons (1992)

The mechanisms leading to anion electron stimulated desorption (ESD) at low energies (0–20 eV) are discussed with emphasis on the formation of transitory anions at surfaces decaying by dissociative attachment (DA). The results of recent measurements are summarized and briefly explained using as examples data on O− ESD from O2 condensed on Pt and H−, CH−, and CH−2 desorption from hydrocarbons also physisorbed on Pt. It is shown that, when O2 and hydrocarbons are coadsorbed on Pt, O− ions formed by DA can undergo reactive scattering with other surface molecules; this reaction leads to the product OH− some of which desorb from the surface.
The Antibacterial Activity of Topical Anesthetics (1997)

The in vitro antibacterial effect of topical anesthetics suggests one possible reason why bacterial culture yields in clinical ulcerative keratitis are suboptimal. We propose that clinicians consider the use of a 1% or 2% cocaine solution instead of standard commercial topical anesthetics in the management of individual cases of ulcerative keratitis and in future clinical bacterial keratitis studies.
Innovative High-Temperature Aircraft Engine Fuel Nozzle Design (1993)

The objective of the Innovative High-Temperature Aircraft Engine Fuel Nozzle Program was to design and evaluate a nozzle capable of operating at a combustor inlet air temperature of 1600°F (1144 K) and a fuel temperature of 350°F (450 K). The nozzle was designed to meet the same performance requirements and fit within the size envelope of a current production F404 dual orifice fuel nozzle. The design approach was to use improved thermal protection and fuel passage geometry in combination with fuel passage surface treatment to minimize coking at these extreme fuel and air temperatures. Heat transfer models of several fuel injector concepts were used to optimize the thermal protection, while a series of sample tube coking tests were run to evaluate the effect of surface finish, coatings, and tube material on the coking rate. Based on heat transfer analysis, additional air gaps, reduced fuel passage flow area, and ceramic tip components reduced local fuel wetted wall temperatures by more than 200°F (110 K) when compared to a current production F404 fuel nozzle. Sample tube coking test results showed the importance of surface finish on the fuel coking rate. Therefore, a 1 μin. (0.025 μm) roughness was specified for all fuel passage surfaces. A novel flow divider valve in the tip was also employed to reduce weight, allow room for additional thermal protection, and provide back pressure to reduce the risk of fuel vaporization. Phase II of this program will evaluate the fuel nozzle with a series of contaminated fuel and coking tests.
Lipid Matrix Systems with Emphasis on Lipid Microspheres: Potent Carriers for Transcutaneous Delivery of Bioactives (2012)

Drug delivery through skin is the major confrontation due to its exceptional barrier properties. Despite major research and development efforts in transdermal systems, low Stratum corneum permeability limits the usefulness of topically administered drugs. This problem is more pronounced with bioactive drugs, which require special formulation technologies to overcome stability issues, their effective localization and safe release. This has led to an increased attention towards effective lipid based topical cutaneous systems. This review provides a brief overview of different lipid based systems, their associated advantages and disadvantages with special emphasis on lipid matrix systems like lipid microspheres or lipospheres and the potential of lipid matrix systems for transdermal delivery of bioactives.
Dictionary learning based on M‐PCA‐N for audio signal sparse representation (2017)

The current popular dictionary learning algorithms for sparse representation of signals are K‐means Singular Value Decomposition (K‐SVD) and K‐SVD‐extended. Only rank‐1 approximation is used to update one atom at a time and it is unable to cope with large dictionary efficiently. In order to tackle these two problems, this study proposes M‐Principal Component Analysis‐N (M‐PCA‐N), which is an algorithm for dictionary learning and sparse representation. First, M‐Principal Component Analysis (M‐PCA) utilised information from the top M ranks of SVD decomposition to update M atoms at a time. Then, in order to further utilise the information from remaining ranks, M‐PCA‐N is proposed on the basis of M‐PCA, by transforming information from the following N non‐principal ranks onto the top M principal ranks. The mathematic formula indicates that M‐PCA may be seen as a generalisation of K‐SVD. Experimental results on the BBC Sound Effects Library show that M‐PCA‐N not only lowers the MSE between original signal and approximation signal in audio signal sparse representation, but also obtains higher audio signal classification precision than K‐SVD.
Adaptive Soft-Decision Aided Differential Modulation for Cooperative Uplink Transmission Relying on Radio-Over-Fiber Backhaul (2014)

A novel adaptive turbo-coded soft-decision aided differential detection (ATSDD) scheme is proposed for cooperative uplink wireless and Radio-over-fiber (ROF) transmission in a Fractional Frequency Reuse (FFR) based multicell, multiuser system. More specifically, the ATSDD scheme is employed by the Mobile Station (MS) for reliably conveying the source bits to a pair of Remote Antennas (RAs) by appropriately adjusting the modulation mode according to the near-instantaneous wireless and ROF channel conditions. The ATSDD switching thresholds are specifically adjusted for ensuring that the Bit Error Ratio (BER) remains below 10^(-5). We also investigated the effect of phase-rotations, which is routinely inflicted by practical imperfect ROF links. We demonstrate that our ATSDD scheme increases the overall throughput.

Leveraging social media for training object detectors (2009)

The fact that most users tend to tag images emotionally rather than realistically makes social datasets inherently flawed from a computer vision perspective. On the other hand they can be particularly useful due to their social context and their potential to grow arbitrary big. Our work shows how a combination of techniques operating on both tag and visual information spaces, manages to leverage the associated weak annotations and produce region-detail training samples. In this direction we make some theoretical observations relating the robustness of the resulting models, the accuracy of the analysis algorithms and the amount of processed data. Experimental evaluation performed against manually trained object detectors reveals the strengths and weaknesses of our approach.
Inside Cover: 2‐(Pyridinium‐1‐yl)‐1,1‐bis(perfluoroalkylsulfonyl)ethan‐1‐ide: A Practical Reagent for Synthesis of Strongly Acidic 1,1‐Bis(perfluoroalkylsulfonyl)alkanes (Chem. Eur. J. 34/2017) (2017)

A shelf-stable, easy-to-handle reagent for the in situ generation of the highly electrophilic alkene (RfSO2)2C=CH2 was developed. By using this reagent, a new type of superacidic molecule was successfully synthesized. The authors also found some synthetic reactions catalyzed by the alkene. Detailed NMR studies revealed a rapid decomposition rate (milliseconds order) of the reagent to generate (RfSO2)2C=CH2/2-fluoropyridine. In this picture, the rapid formation of (RfSO2)2C=CH2 is represented by cracking open a raw egg. This egg is also a symbol for the birth of new chemistry.

A Sliding Mode Observer Based ABS for Aircraft and Land Vehicles (2003)

&lt;div class="htmlview paragraph"&gt;Control of an antilock brake system for aircraft and land vehicles is based upon estimates of the torque applied to braking wheels by means of a sliding mode observer. The observer yields a highly accurate estimate of torque that is robust for the entire operating range of the brakes, and provides an input to a relatively simple control system that regulates applied torque from either an electro-hydraulic or electromechanical actuator. Excellent braking performance for a regional jet transport is demonstrated in this paper via hardware-in-the-loop simulation. A simple scheme for suppressing gear walk (aircraft application) is presented.&lt;/div&gt;
Association of Baseline Peptidylarginine Deiminase 4 Autoantibodies With Favorable Response to Treatment Escalation in Rheumatoid Arthritis (2018)

Although anti-PAD4 antibodies were associated with worse baseline radiographic joint damage, suggesting a history of active or undiagnosed disease, treatment escalation therapy was more effective in reducing disease activity and slowing the progression of joint damage in this patient subset.
WE-D-332-03: How Well Does CTDI Estimate Organ Dose to Patients From Multidetector (MDCT) Imaging? (2008)

Purpose: Although CTDI was designed to characterize CT scanner performance, it is often used to estimate patient dose. This study uses voxelized patient models based on actual patient anatomy and Monte Carlo based MDCT simulations to answer the question: how well does CTDI predict patient organ dose? Method and Materials: 26 voxelized models of female anatomy of various sizes were created from clinical CT data. Breast tissue was contoured by a radiologist and glandular and lung tissues automatically segmented. A previously validated Monte Carlo model of an MDCT scanner was used taking into account source spectra, filtration, collimation, and geometry. Two fixed mA clinical acquisition protocols were simulated: Chest CT and retrospectively gated coronary CTA. For each exam, doses were calculated for breast and lung tissues, and compared to CTDIvol (=CTDIw/pitch), CTDI100center/pitch, and CTDI100periphery/pitch. Percent difference between each CTDI value and organ dose was calculated and the mean of these differences was reported. Results: For the Chest CT Protocol: CTDIvol measurements differ from breast and lung dose by an average of 84% and 52% respectively. CTDIperiphery/pitch differs from breast and lung dose by an average of 117% and 80% respectively; CTDIcenter/pitch differs from breast and lung dose by an average of 18% and 3% respectively. For the CTA Protocol: CTDIvol measurements differ from breast and lung dose by an average of 34% and 16% respectively. CTDIperiphery/pitch differs from breast dose and lung dose by an average of 58% and 37% respectively; CTDIcenter/pitch differs from breast and lung dose by an average of 15% and 26% respectively. Conclusion: CTDIvol generally overestimates organ dose, while CTDIcenter /pitch provides better estimates of organ dose; Organ dose is affected by patient size (i.e. perimeter); therefore, future work will look into the possibility of scaling CTDI measurements to estimate organ dose based on patient size.
Neutron-induced single event burnout in high voltage electronics (1997)

Energetic neutrons with an atmospheric neutron spectrum, which were demonstrated to induce single event burnout in power MOSFETs, have been shown to induce burnout in high voltage (>3000 V) electronics when operated at voltages as low as 50% of rated voltage. The laboratory failure rates correlate well with field failure rates measured in Europe.
Potassium carbonate as a supplement to improve milk fat concentration and yield in early-lactating dairy goats fed a high-starch, low-fiber diet (2021)

This study investigated the use of K<sub>2</sub>CO<sub>3</sub> as dietary buffer to prevent or to recover from low milk fat production when early-lactating dairy goats are fed a high-starch, low-fiber (HSLF) diet. At kidding, 30 Alpine goats housed in pens with Calan gate feeders received a total mixed ration with a forage-to-concentrate ratio of 55:45 on a dry matter (DM) basis for a baseline period of 27 ± 4 d. Goats (milk yield, 4.14 ± 0.88 kg/d; milk fat, 4.28 ± 0.52%; mean ± SD) were then assigned to 1 of 10 blocks according to parity (first vs. second or more) and milk fat concentration, and fed a HSLF diet containing 45% forages and 55% concentrates for 2 experimental periods of 28 d. Treatments were identified as (1) control, in which the HSLF diet was fed throughout both periods; (2) preventive, in which the HSLF diet supplemented with K<sub>2</sub>CO<sub>3</sub> (1.6% of DM) was fed during both periods; and (3) recovery, in which the HSLF diet was fed during the first period (P1) and the HSLF diet supplemented with K<sub>2</sub>CO<sub>3</sub> was fed during the second period (P2). Data from P1 and P2 were analyzed separately. In P1, preplanned contrasts were used to evaluate the preventive effect of K<sub>2</sub>CO<sub>3</sub> (control and recovery, both groups receiving the same diet during this period, vs. preventive), and in P2, to assess the potential of K<sub>2</sub>CO<sub>3</sub> to alleviate an already existing state of low milk fat (control vs. recovery and preventive vs. recovery). Feeding the HSLF diet in P1 moderately decreased milk fat concentration (-16%) and yield (-13%) as compared with baseline. Dietary addition of K<sub>2</sub>CO<sub>3</sub> decreased DM intake by 12 and 14% in P1 and P2, respectively. Ruminal pH was not different among treatments. There was also no significant difference in milk yield (4.13 and 3.71 kg/d on average in P1 and P2, respectively) for any tested contrasts. In P1, milk fat concentration and yield did not differ among goats fed control (3.58% and 151 g/d, respectively) and preventive (3.67% and 148 g/d, respectively) diets. In P2, milk fat concentration and yield did not differ among goats fed the control diet (3.38% and 137 g/d, respectively), and diets where K<sub>2</sub>CO<sub>3</sub> was used as preventive (3.44% and 126 g/d, respectively) or recovery treatment (3.25% and 113 g/d, respectively). Supplementing a high-concentrate diet with 1.6% K<sub>2</sub>CO<sub>3</sub> was therefore not effective in either preventing or suppressing already existing conditions of low milk fat production in dairy goats.
