Revisiting culture and language in global management teams (2017)

In research on international business (IB) and management, a narrow view of language and culture has given way to a greater understanding of the complexity of the interplay of language- and culture-related issues in today’s world. The “linguistic turn” in the social sciences along with the more recent unravelling of the deterministic cultural dimension has led to reexamining the importance of language and culture in the social construction of reality. The key role played by multicultural, multilingual teams in organizations operating on a global scale has spawned much research on the impact of language and cultural diversity within teams. Some scholars have focused on the negative aspects of diversity implying that language standardization, through the adoption of lingua franca policies and practices, is the most appropriate strategy for collaboration across languages and borders. Others have uncovered the positive side of this diversity; they argue the case for the coexistence of different working languages together with communication practices that facilitate the contextualization necessary for sense-making processes in multilingual teams. This has led a growing number of scholars within different research fields to take the “multilingual turn” exploring novel ideas and concepts emerging around the phenomena of multilingualism, thereby advancing the discussion in IB and management studies. Applying these emerging notions to a study of a multilingual team in an international organization, we question the widely held assumptions about language, culture, and identity and show the need to refresh the way in which these concepts are framed when examining team performance.

Accelerating Topic Model Training on a Single Machine (2013)

Abstract. We present the design and implementation of GLDA, a library that utilizes the GPU (Graphics Processing Unit) to perform Gibbs sampling of La-tent Dirichlet Allocation (LDA) on a single machine. LDA is an effective topic model used in many applications, e.g., classification, feature selection, and infor-mation retrieval. However, training an LDA model on large data sets takes hours, even days, due to the heavy computation and intensive memory access. Therefore, we explore the use of the GPU to accelerate LDA training on a single machine. Specifically, we propose three memory-efficient techniques to handle large data sets on the GPU: (1) generating document-topic counts as needed instead of stor-ing all of them, (2) adopting a compact storage scheme for sparse matrices, and (3) partitioning word tokens. Through these techniques, the LDA training which would take 10 GB memory originally, can be performed on a commodity GPU card with only 1 GB GPU memory. Furthermore, our GLDA achieves a speedup of 15X over the original CPU-based LDA for large data sets. 1
Functional interactions between<i>chpB</i>and<i>parD</i>, two homologous conditional killer systems found in the<i>Escherichia coli</i>chromosome and in plasmid R1 (1998)

parD and chpB are homologous conditional killer systems of plasmid and chromosomal origin, respectively. They are bicistronic operons encoding a killer protein (Kid and ChpBK) and an antidote (Kis and ChpBI). It is shown that the antidote of the chpB system can neutralize the toxin of the parD system. This activity is improved by particular amino acid changes at the amino end of the ChpBI antidote. It is further shown that the chpB system is weakly autoregulated and that the activity of a second promoter, previously identified upstream of the regulated promoter, can modulate the functional interactions between the chpB and parD systems.
Magnesium‐Lanthanum Mixed Metal Oxide: a Strong Solid Base for the Michael Addition Reaction (2005)

Abstract Michael additions were achieved quantitatively at room temperature with a broad spectrum of acceptors and donors, using a magnesium‐lanthanum mixed oxide, a strong solid base. The best solvent for the reaction is dimethylformamide, but good yields were also obtained using toluene as solvent. The results obtained with magnesium‐lanthanum are comparable to those reported for super bases. The catalyst can be separated from the reaction mixture and recycled five times without loss of activity with no other treatment.
Defining and translating a "safe" subset of simulink/stateflow into lustre (2004)

The Simulink/Stateflow toolset is an integrated suite enabling model-based design and has become popular in the automotive and aeronautics industries. We have previously developed a translator called Simtolus from Simulink to the synchronous language Lustre and we build upon that work by encompassing Stateflow as well. Stateflow is problematical for synchronous languages because of its unbounded behaviour so we propose analysis techniques to define a subset of Stateflow for which we can define a synchronous semantics. We go further and define a "safe" subset of Stateflow which elides features which are potential sources of errors in Stateflow designs. We give an informal presentation of the Stateflow to Lustre translation process and show how our model-checking tool Lesar can be used to verify some of the semantical checks we have proposed. Finally, we present a small case-study.
X-band T/R-module front-end based on GaN MMICs (2009)

Amplifiers for the next generation of T/R modules in future active array antennas are realized as monolithically integrated circuits (MMIC) on the basis of novel AlGaN/GaN (is a chemical material description) high electron mobility transistor (HEMT) structures. Both low-noise and power amplifiers are designed for X-band frequencies. The MMICs are designed, simulated, and fabricated using a novel via-hole microstrip technology. Output power levels of 6.8 W (38 dBm) for the driver amplifier (DA) and 20 W (43 dBm) for the high-power amplifier (HPA) are measured. The measured noise figure of the low-noise amplifier (LNA) is in the range of 1.5 dB. A T/R-module front-end with mounted GaN MMICs is designed based on a multi-layer low-temperature cofired ceramic technology (LTCC).
Photoaffinity Labeling of a Peptide Substrate to Myosin Light Chain Kinase (1995)

The substrate binding properties of skeletal muscle myosin light chain kinase were investigated with a synthetic peptide containing the photoreactive amino acid p-benzoylphenylalanine (Bpa) incorporated amino-terminal of the phosphoacceptor serine (BpaKKRAARATSNVFA). When photolyzed at 350 nm, the peptide was cross-linked stoichiometrically to myosin light chain kinase in a Ca2+/calmodulin-dependent manner. Peptide incorporation into kinase inhibited light chain phosphorylation, and the loss of kinase activity was proportional to the extent of peptide incorporated. After peptide I was incorporated into myosin light chain kinase, it was partially phosphorylated in the absence of Ca2+/calmodulin. The extent of phosphorylation increased in the presence of Ca2+/calmodulin. The cross-linked photoadduct was digested, labeled peptides were purified by high performance liquid chromatography, and sites of covalent modification were determined by amino acid sequencing and analysis. The covalent modification in the catalytic core occurred on Ile-373 (66%) and in a peptide containing residues Asn-422 to Met-437 (14%), respectively. Lys-572 in the autoinhibitory region accounted for 20% of the incorporated label. The coincident covalent modification of the autoinhibitory domain suggests that it is located near the catalytic site. Based upon a model of the catalytic core, the substrate peptide is predicted to bind in the cleft between the two lobes of the kinase. The orientation of the substrate peptide on myosin light chain kinase is similar to the orientation of the substrate recognition fragment, but not the high affinity binding fragment, of inhibitor peptide of cAMP-dependent protein kinase in the catalytic subunit of the cAMP-dependent protein kinase.
Non-Invasive Techniques for Detection and Diagnosis of Oral Potentially Malignant Disorders (2016)

Oral squamous cell carcinoma (OSCC) is the most common oral and maxillofacial malignancy, and its morbidity and mortality rates are still high in most countries. Oral potentially malignant disorders (PMDs) are used to refer to a heterogeneous group of conditions that are characterized by increased risk for malignant transformation to OSCC. Currently identified oral PMDs include leukoplakia, erythroplakia, palatal lesions associated with reverse smoking, oral lichen planus, oral submucous fibrosis, actinic keratosis, and discoid lupus erythematosus. The early detection and diagnosis of these lesions are important for cancer prevention and disease management. In recent years, there has been a growing and persistent demand for new non-invasive, practical diagnostic techniques that might facilitate the early detection of oral PMDs. The non-invasive detection techniques evaluated in this review are divided into four categories: vital staining with a solution that can be used as a mouth rinse or applied onto a suspected area of the mouth, light-based detection systems, optical diagnostic technologies that employ returned optical signals to reflect structural and morphological changes within tissues, and salivary biomarkers. Most of these techniques have shown great potential for screening and monitoring oral PMDs. In this review article, the authors critically assess these non-invasive detection techniques for oral PMDs. We also provide a summary of the sensitivity and specificity of each technique in detecting oral PMDs and oral cancer, as well as their advantages, disadvantages, clinical applications, and indications.
Morphology of Stored, Rejuvenated Human Erythrocytes (1975)

Whole blood was stored at 4°C for 42 days. At 7-day intervals, starting with day 21, aliquots were rejuvenated with a phosphate, inosine, glucose pyruvate, and adenine solution. Samples were taken for ATP assays and red cell morphology (by SEM) both before and after rejuvenation. Rejuvenation elevated all ATP levels in excess of 100% of the starting values and significantly increased the percent of cells in the discoid shape as measured by their morphological index, showing that rejuvenation not only raises the cell’s metabolic level but causes partial reversion to fresh cell morphology.
Modeling Teleoperated Robot Driving Performance as a Function of Environment Difficulty**This research was supported by the Automotive Research Center at the University of Michigan, with funding from government contract DoD-DoA W56HZV-14-2-0001 through the US Army Tank Automotive Research, Development, and Engineering Center. (2016)

Modeling mobile robot driving performance is a challenging task, but a simple, accurate model can be helpful in making robot system design decisions that balance cost and performance. Driving performance can depend on a variety of factors including human ability, capabilities of the physical robot, and characteristics of the robot's environment (e.g. obstacles, terrain). This paper investigates teleoperated robot driving time for a task that includes obstacles in an environment. We hypothesize that a model analogous to Fitts’ Law can be used to describe robot performance (driving time) as a function of environment difficulty. A new definition of the difficulty index (ID) in Fitts' Law is proposed in this paper that describes an environment's difficulty based on the arrangement of obstacles. The model is tested with data from a human subject study we conducted, in which a simulated differential drive robot was teleoperated through different environments in a manual control mode and semi-autonomous mode (obstacle avoidance). We demonstrate that the model for driving time and our proposed environment difficulty index fit human subject data well for a simple driving task between one pair of obstacles. Additionally, the model is expanded to predict driving time in a more complex environment with multiple pairs of obstacles. The results of this paper provide a building block for predicting teleoperated driving time performance in larger, more complex environments.
Diagnosis features of thoracic spinal epidural abscess without fever and review of literature (2017)

Objective
To explore the diagnosis features of spinal epidural abscess (SEA).


Methods
The clinical data of 1 case of SEA without fever was analyzed retrospectively.Literatures were reviewed and features of clinical diagnosis of SEA were summarized.


Results
The patient was an old man, and was admitted to department of spine surgery of Affiliated Hospital of Jining Medical University for low back pain and paralysis of lower limbs.He had a history of diabetes mellitus for more than 3 years without taking medicine to control his blood sugar.On admission, his body temperature was 36.8℃, blood sugar 8.2 mmol/L, initial white-cell count 10.80×109/L (83.60% neutrophils), and serum C-reactive protein 82 mg/L.MRI revealed abnormal high signal in T7-11 segment of intraspinal epidural space at admission.Decompressive laminectomy was performed urgently.During the operation, the white viscous pus in the spinal canal was observed and the pus was taken for bacterial culture.The result of bacterial culture was Staphylococcus aureus.Postoperative MRI scan which performed on the nineteenth day after surgery revealed the spine has been decompressed successfully.After 10 months follow-up, the lower limbs recovered.


Conclusions
Clinically, SEA is an uncommon disorder, and the early diagnosis of SEA is difficult, especially SEA without fever.The accurate diagnosis needs a combination of clinician experience, clinical manifestation in patients, laboratory examination and imaging assays.Patients with diabetes mellitus are the highest risk subgroup of SEA.When the diabetic patients with low back pain and the increase of inflammatory markers, spinal epidural abscess should be considered, although patient′s body temperature is normal.And further, MRI should be carried out to clarify the diagnosis.

Introduction: an Age of Political Stability? (1984)

It is not necessary to resort to ministerial propaganda, as quoted above, in order to note features of stability in this period. The most dramatic was the longevity of the Walpole government. Walpole dominated British politics for over twenty years, a ministry that contrasted with the preceding and succeeding periods of short governments and a perpetual sense of political instability. To contemporaries this longevity was the most dramatic political feature of the period. Its causes and consequences were much debated, and political assumptions and practices were tested at the time and they have been the subject of historical debate ever since. It is this ministerial longevity that is the most distinctive and widely debated feature of the Walpolean era, and this introduction will not only seek to draw attention to the main reasons for it but will also intimate its limitations.
Optimizing communication and cooling costs in HPC data centers via intelligent job allocation (2013)

Nearly half of the energy in the computing clusters today is consumed by the cooling infrastructure. It is possible to reduce the cooling cost by allowing the data center temperatures to rise; however, component reliability constraints impose thermal thresholds as failure rates are exponentially dependent on the processor temperatures. Existing thermally-aware job allocation policies optimize the cooling costs by minimizing the peak inlet temperatures of the server nodes. An important constraint in high performance computing (HPC) data centers, however, is performance. Specifically, HPC data centers run multi-threaded applications with significant communication among the threads. Thus, performance of such applications is strongly affected by the job allocation decisions. This paper proposes a novel job allocation methodology to jointly minimize communication cost of an HPC application while also reducing the cooling energy. The proposed method also considers temperature-dependent hardware reliability as part of the optimization.
Key Enabling Technologies for Optical–Wireless Networks: Optical Millimeter-Wave Generation, Wavelength Reuse, and Architecture (2007)

The integration of optical and wireless systems is considered to be one of the most promising solutions for increasing the existing capacity and mobility as well as decreasing the costs in next-generation optical access networks. In this paper, several key enabling technologies for hybrid optical-wireless access networks are described, including optical millimeter-wave (mm-wave) generation, upconversion, and transmission in a downlink direction, and full-duplex operation based on wavelength reuse by using a centralized light source in an uplink direction. By employing these enabling technologies, we design and experimentally demonstrate an optical-wireless testbed that is simultaneously delivering wired and wireless services in the integrated optical-wireless and wavelength-division-multiplexing passive-optical-network access networks. The actual applications consisting of 270-Mb/s uncompressed standard-definition TV signal and 2.5-Gb/s data channels for downstream are successfully transmitted over a 25-km fiber and a 10.2-m indoor wireless link with less than a 1.5-dB power penalty. The results show that this integrated system is a practical solution to deliver superbroadband information services to both stationary and mobile users.
Location of the amino acid differences in the S1 spike glycoprotein subunit of closely related serotypes of infectious bronchitis virus (1992)

Four UK strains of three different serotypes were found to differ by only 2-3% of their S1 amino acids. The S1 sequences were also very similar to those of three Dutch isolates (D207, D274 and D3896), the greatest difference between two of the seven isolates being 4.4%. The few amino acid differences between the seven isolates were located largely between residues 19-122 and 251-347 of the mature S1 subunit. The seven isolates could be differentiated using 16 monoclonal antibodies in an enzyme-linked immunosorbent assay. Some virus neutralizing (VN) antibody-inducing epitopes were common to all seven isolates even though the strains had been differentiated into three serotypes by polyclonal sera. The results indicate that the most antigenic of the VN antibody-inducing epitopes are formed by very few amino acids and that these occur in the first and third quarters of the S1 subunit. We suggest that serology-based epizootiological studies of IBV should, therefore, be augmented by the inclusion of nucleic acid sequencing and/or monoclonal antibody analysis.
Ultrastructure and Composition of the Nannochloropsis gaditana Cell Wall (2014)

Marine algae of the genus Nannochloropsis are promising producers of biofuel precursors and nutraceuticals and are also harvested commercially for aquaculture feed. We have used quick-freeze, deep-etch electron microscopy, Fourier transform infrared spectroscopy, and carbohydrate analyses to characterize the architecture of the Nannochloropsis gaditana (strain CCMP 526) cell wall, whose recalcitrance presents a significant barrier to biocommodity extraction. The data indicate a bilayer structure consisting of a cellulosic inner wall (~75% of the mass balance) protected by an outer hydrophobic algaenan layer. Cellulase treatment of walls purified after cell lysis generates highly enriched algaenan preparations without using the harsh chemical treatments typically used in algaenan isolation and characterization. Nannochloropsis algaenan was determined to comprise long, straight-chain, saturated aliphatics with ether cross-links, which closely resembles the cutan of vascular plants. Chemical identification of >85% of the isolated cell wall mass is detailed, and genome analysis is used to identify candidate biosynthetic enzymes.
A Radio Frequency Driven DC Electron Beam Source (1999)

A 3 cm diameter disc shaped plasma generated electron beam source, employing ion-induced secondary electron emission from cold cathodes has been demonstrated. An inductively coupled plasma generated in 2–20 mTorr argon feedstock gas provides ions which impinge on the high secondary electron emission coefficient Al 2 O 3 cathode. A separate 13.56 MHz radio frequency bias voltage is applied to the cathode and thereby provides the effective DC field for both ion impingement and electron beam acceleration as described herein. A differentially pumped retarding potential analyzer measures the electron beam energy spectra at a location 14 cm from the cold cathode. It is found that the maximum (negative) cathode voltage sets the maximum electron beam energy, and the electron beam current is roughly set by the inductively coupled plasma power, which corresponds to the ion flux to the cathode. A crude model relating the electron beam energy spectra to the time varying cathode sheath potential provided by the rf bias shows good agreement with measured results.
Quantitative transmission electron microscopy analysis of multi-variant grains in present L1-FePt based heat assisted magnetic recording media (2014)

We present a study on atomic ordering within individual grains in granular L10-FePt thin films using transmission electron microscopy techniques. The film, used as a medium for heat assisted magnetic recording, consists of a single layer of FePt grains separated by non-magnetic grain boundaries and is grown on an MgO underlayer. Using convergent-beam techniques, diffraction patterns of individual grains are obtained for a large number of crystallites. The study found that although the majority of grains are ordered in the perpendicular direction, more than 15% of them are multi-variant, or of in-plane c-axis orientation, or disordered fcc. It was also found that these multi-variant and in-plane grains have always grown across MgO grain boundaries separating two or more MgO grains of the underlayer. The in-plane ordered portion within a multi-variant L10-FePt grain always lacks atomic coherence with the MgO directly underneath it, whereas, the perpendicularly ordered portion is always coherent with the underlying MgO grain. Since the existence of multi-variant and in-plane ordered grains are severely detrimental to high density data storage capability, the understanding of their formation mechanism obtained here should make a significant impact on the future development of hard disk drive technology.
