Effects of 5 insecticidal regulatory genes on Cr(VI) detoxification of Bacillus thuringiensis 407

This study aimed to investigate the effects of insecticidal regulatory genes on Cr(Ⅵ) detoxification of Bacillus thuringiensis 407. The growth curve of Bt 407 and its mutants(407 ΔplcR, 407 ΔinhA2, 407 ΔmpbE, 407 ΔsigmaE and 407 ΔsigmaK) were applied to determine the t0(time of the strain enter into the stationary phase). The Cr(VI) and total Cr concentrations at t-3(3 h before t0), t-2(2 h before t0), t-1(1 h before t0), t0, t1(1 h after t0), t2(2 h after t0), t3(3 h after t0) and t4(4 h after t0) were also detected. The genomic sequence of Bt 407 was analyzed for the existence of Cr(Ⅵ) resistant genes. And the model chart of Bt 407 Cr(Ⅵ) detoxification was primarily constructed. The results showed that PlcR, InhA2, MpbE and SigmaK negatively regulated the detoxification of Cr(Ⅵ) by reducation, while SigmaE had no effects on the process. Cr(Ⅵ) resistant genes azoR, efx and chrA were obtained by genomic analysis of Bt 407. The mechanisms of Cr(Ⅵ) detoxification by Bt 407 was proposed as follows: AzoR reduces Cr(Ⅵ) to Cr(Ⅲ), which is negatively regulated by PlcR, InhA2, MpbE and SigmaK. The efflux of chromium was conferred by antiporters Efx and ChrA. These results suggested that the resistance of Bt 407 to Cr(Ⅵ) is a complicated network regulated by azoR, efx, chrA, plcR, inhA2, mpbE and sigmaK genes.
Movie Music in Gravity's Rainbow

Most of the songs in Gravity's Rainbow appear to be based, some closely, some loosely, on already existing songs to which Pynchon has written new lyrics. Appropriate to the nexus of film allusions and images in the text, some of Pynchon's songs are based on music written for the movies. I have identified specific sources for two songs that have not previously been accounted for. Together, the two allusions illustrate the contradictory ways the narrator of Gravity's Rainbow uses film references.
Carcinoma of the Prostate in the Elderly: The Therapeutic Ratio of Definitive Radiotherapy

AbstractWithholding or reducing the intensity and aggressiveness of treatment for elderly cancer patients is a widespread tenet lacking substantiation in the literature. To assess the potential value of definitive external beam radiotherapy in the elderly, an analysis of the therapeutic ratio between local regional control and complications was performed in 34 prostatic cancer patients more than 75 years old. Median followup was 5 years (range 2 to 8 years). The 5-year actuarial local regional control rate was 91 per cent. The 5-year actuarial survival rate was 81 per cent and the 5-year survival rate free of disease was 63 per cent. There were no severe complications. Mild to moderate chronic complications occurred in 3 patients (9 per cent). This treatment resulted in an excellent therapeutic ratio, which demonstrates that external beam radiation can be given to elderly patients with acceptable morbidity and gratifying results.
Nasopharyngeal Carcinoma and Squamous Cell Carcinoma of the Paranasal Sinuses

Nasopharyngeal carcinoma (NPC) is the most common primary malignancy of the nasopharynx. The WHO divides NPC into three subtypes: Type 1 (I) is squamous cell carcinoma; Type 2a (II) is keratinizing undifferentiated carcinoma; Type 2b (III) is nonkeratinizing undifferentiated carcinoma.
Problems in Classroom Engagement: Validation of an Assessment for District-Wide Use in the Early Primary Grades.

ABSTRACTResearch Findings: The aim of this study was to provide an initial investigation into the psychometric properties of the Problems in Classroom Engagement Scale (PCES). The PCES was designed and tested for district-wide use as part of the report card system for a large urban school district. The PCES was administered to all 1st-, 2nd-, and 3rd-grade students in the district. Factor analytic examination revealed a bifactor structure as the best fit to the data. The bifactor structure reflected a general factor of Problems in Behavioral Engagement and two group factors: Problems in Social Engagement and Problems in Academic Engagement. These factors were found to be reliable within and across grades and demonstrated convergent and divergent relations with academic and behavioral outcomes. Practice or Policy: Findings provide initial evidence to support the routine use of the PCES in a large urban setting. The use of the PCES can help in fostering district-wide attention to students’ early difficultie...
Politicized Enforcement in Argentina: Labor and Environmental Regulation

Countries throughout the world have passed regulations that promise protection for workers and the environment, but violations of these policies are more common than compliance. All too often, limitations of state capacity and political will intertwine, hindering enforcement. Why do states enforce regulations in some places, and in some industries, but not in others? In Politicized Enforcement in Argentina, Amengual develops a framework for analyzing enforcement in middle-income and developing countries, showing how informal linkages between state officials and groups within society allow officials to gain the operational resources and political support necessary for enforcement. This analysis builds on state-society approaches in comparative politics, but in contrast to theories that emphasize state autonomy, it focuses on key differences in the way states are porous to political influence.
Beings of a Feather: Learning About the Lives of Birds with Amazonian Peoples

This article is a memoir of the author's fieldwork experiences studying traditional knowledge of bird species in the Peruvian Amazon. It describes his growth as a researcher, in light of the practical and methodological challenges of carrying out this kind of work. It also relates how the author's thinking has evolved on questions of current theoretical interest in ethnobiology. The first section outlines how the author came to be interested in this topic while pursuing an ethnobotanical dissertation project. Next, the discussion follows his work with the indigenous Aguaruna and Iquito peoples, learning about and documenting their understandings of the nesting, foraging and reproductive behavior of local avian species. On one hand, he found that local people provided details of these behaviors that match, in many ways, the counts of academic ornithologists. However, local interpretations of why these behaviors take place are often framed by some very different assumptions. The author uses Victor Toledo's tripartite framework of kosmos (overarching belief systems), corpus (cognitive categories), and praxis (set of practices) to discuss similarities and differences in Aguaruna, Iquito, and academic ornithology. He also discusses his progression of views on the topic of perspectivism and eventual preference for a theoretical framework favoring a polyontological approach to understanding Amazonian ethnoecology.

Quality Measures in Orthopaedic Sports Medicine: A Systematic Review

Purpose To report the current quality measures that are applicable to orthopaedic sports medicine physicians. Methods Six databases were searched with a customized search term to identify quality measures relevant to orthopaedic sports medicine surgeons: MEDLINE/PubMed, EMBASE, the National Quality Forum (NQF) Quality Positioning System (QPS), the Agency for Healthcare Research and Quality (AHRQ) National Quality Measures Clearinghouse (NQMC), the Physician Quality Reporting System (PQRS) database, and the American Academy of Orthopaedic Surgeons (AAOS) website. Results were screened by 2 Board-certified orthopaedic surgeons with fellowship training in sports medicine and dichotomized based on sports medicine–specific or general orthopaedic (nonarthroplasty) categories. Hip and knee arthroplasty measures were excluded. Included quality measures were further categorized based on Donabedian's domains and the Center for Medicare and Medicaid (CMS) National Quality Strategy priorities. Results A total of 1,292 quality measures were screened and 66 unique quality measures were included. A total of 47 were sports medicine–specific and 19 related to the general practice of orthopaedics for a fellowship-trained sports medicine specialist. Nineteen (29%) quality measures were collected within PQRS, with 5 of them relating to sports medicine and 14 relating to general orthopaedics. AAOS Clinical Practice Guidelines (CPGs) comprised 40 (60%) of the included measures and were all within sports medicine. Five (8%) additional measures were collected within AHRQ and 2 (3%) within NQF. Most quality measures consist of process rather than outcome or structural measures. No measures addressing concussions were identified. Conclusions There are many existing quality measures relating to the practice of orthopaedic sports medicine. Most quality measures are process measures described within PQRS or AAOS CPGs. Clinical Relevance Knowledge of quality measures are important as they may be used to improve care, are increasingly being used to determine physician reimbursement, and can inform future quality measure development efforts.
Denosumab: an Emerging Therapy in Pediatric Bone Disorders.

Denosumab is an inhibitor of receptor activator of nuclear factor kappa-B ligand (RANKL), and has emerged as an important novel therapy for skeletal disorders. This article examines the use of denosumab in children. Considerable safety and efficacy data exists for denosumab treatment of adults with osteoporosis, bone metastases, and giant cell tumors. Pediatric data is limited; however, evidence suggests denosumab may be beneficial in decreasing bone turnover, increasing bone density, and preventing growth of certain skeletal neoplasms in children. Denosumab’s effect on bone turnover is rapidly reversible after drug discontinuation, representing a key difference from bisphosphonates. Rebound increased bone turnover has led to severe hypercalcemia in several pediatric patients. Denosumab is a promising therapy for pediatric skeletal disorders. At present, safety concerns related to rebounding bone turnover and mineral homeostasis impact use of denosumab in children. Research is needed to determine if and how these effects can be mitigated.
Impact of cap-assisted colonoscopy on the learning curve and quality in colonoscopy: a randomized controlled trial

Background and Aims Colonoscopy competency assessment in trainees traditionally has been informal. Comprehensive metrics such as the Assessment of Competency in Endoscopy (ACE) tool suggest that competency thresholds are higher than assumed. Cap-assisted colonoscopy (CAC) may improve competency, but data regarding novice trainees are lacking. We compared CAC versus standard colonoscopy (SC) performed by novice trainees in a randomized controlled trial. Methods All colonoscopies performed by 3 gastroenterology fellows without prior experience were eligible for the study. Exclusion criteria included patient age 90 years, pregnancy, prior colon resection, diverticulitis, colon obstruction, severe hematochezia, referral for EMR, or a procedure done without patient sedation. Patients were randomized to either CAC or SC in a 1:1 fashion. The primary outcome was the independent cecal intubation rate (ICIR). Secondary outcomes were cecal intubation time, polyp detection rate, polyp miss rate, adenoma detection rate, ACE tool scores, and cumulative summation learning curves. Results A total of 203 colonoscopies were analyzed, 101 in CAC and 102 in SC. CAC resulted in a significantly higher cecal intubation rate, at 79.2% in CAC compared with 66.7% in SC ( P = .04). Overall cecal intubation time was significantly shorter at 13.7 minutes for CAC versus 16.5 minutes for SC ( P =.02). Cecal intubation time in the case of successful independent fellow intubation was not significantly different between CAC and SC (11.6 minutes vs 12.7 minutes; P = .29). Overall ACE tool motor and cognitive scores were higher with CAC. Learning curves for ICIR approached the competency threshold earlier with cap use but reached competency for only 1 fellow. The polyp detection rate, polyp miss rate, and adenoma detection rate were not significantly different between groups. Conclusions CAC resulted in significant improvement in ICIR, overall ACE tool scores, and trend toward competency on learning curves when compared with SC in colonoscopy trainees without prior colonoscopy experience.

The Molecular and Cellular Mechanisms of Zebrafish Lateral Line Development

In aquatic vertebrates, the lateral line mechanosensory system allows for sensation of changes in water current and mediates such behaviors as schooling, predator avoidance, and mating. The lateral line forms from placodes that arise just rostral and caudal to the otic placode. Shortly after placode formation, groups of cells will delaminate from the placodes and begin migrating either throughout the head or down the trunk of the developing embryo. These migratory groups of cells are known as the sensory ridges (head) and posterior lateral line primordium (trunk). During migration, they deposit cell clusters containing hair cell precursors. Shortly after deposition, these clusters will differentiate into mechanosensory organs called neuromasts. In larvae and adults, the lateral line system continues to elaborate; this is accomplished through a differentiation of latent precursors (larvae) as well as a cellular budding process (larvae and adults), resulting in strings of neuromasts that populate the body of aquatic vertebrates. The zebrafish (Danio rerio) has emerged as an exquisite model to study the formation and function of the lateral line system. This chapter describes the development of the zebrafish lateral line and the associated axonal innervations that make up the mechanosensory system.

Electron Spin Resonance in Catalysis

Publisher Summary The electron spin resonance (ESR) technique has been extensively used to study paramagnetic species that exist on various solid surfaces. These species may be supported metal ions, surface defects, or adsorbed molecules and ions. In surface studies, the g tensor has been used mainly (1) to aid in the assignment of spectra, (2) to study the effect of the crystal field upon the energy levels of a paramagnetic species, and (3) to determine the motion of an adsorbed radical. Although a number of factors are considered when assigning an ESR spectrum to a particular species, the experimental g tensor must be consistent with the theoretical g tensor, provided the latter can be determined with any degree of certainty. Interactions between one or more nuclei and the unpaired electron yield a wealth of information concerning molecular structure. In addition, they have proven invaluable in the identification of paramagnetic species. Hyperfine interaction has also been used to study adsorption sites on several catalysts.
Selecting Cases for Whom Additional Tests Can Improve Prognostication

Prognostic models are increasingly being used in clinical practice. The benefit of adding variables (e.g., gene expression measurements) to an original set of variables (e.g., phenotypes) when building prognostic models is usually measured on a whole set of cases. In practice, however, including additional information only helps build better models for some subsets of cases. It is important to prioritize who should undergo further testing. We present a method that can help identify those patients might benefit from additional testing. Our experiments based on limited breast cancer data indicate that relatively old patients with large tumors and positive lymph nodes constitute a group for whom prognoses can be more accurate with the addition of gene expression measurements. The same is not true for some other groups.
Obstructive Kidney Disease

Obstructive kidney disease is a common urologic diagnosis and includes kidney stones, polycystic kidney disease, and renal artery stenosis. Kidney stones are a common emergency department admission in the United States. Men are affected more than women. Polycystic kidney disease is a genetic renal disease that may not reveal symptoms until an individual reaches age 30 years. Renal artery stenosis contributes to decreased perfusion to the kidneys, which contributes to hypertension and end-stage renal disease.
Role of logistics strategy, coordination and customer service commitment on Chinese manufacturing firm competitiveness

The purpose of this paper is to assess the robustness of the three (Bowersox and Daugherty, 1987) dimensions (process, market and information strategies) of logistics strategy in a Chinese manufacturing environment. In addition, the impact of the three dimensions, coordination and customer service on the organizational competitiveness of Chinese manufacturers firms is explored.,The authors conducted an online survey hosted at Sojump.com and disseminated to members of a manufacturing trade association. A total of 513 completed responses were generated. Confirmatory factor analysis (CFA) and structural equation model (SEM) were used to test the hypothesized relationships in the conceptual model.,The findings suggest that the three dimensions of the Bowersox and Daugherty (1987) were relevant to the Chinese manufacturing environment. The authors also found that the overall logistics strategy measured by the three dimensions as well as coordination and customer service effectiveness positively influenced Chinese manufacturing firms’ competiveness.,Further research into logistics and supply chain management may benefit from expanding the understanding to include antecedents and moderating factors (e.g. competition, market turbulence and differences in business environment) into the model. Future studies on cross-cultural logistics/supply chain management logistics may benefit from the application of strategy-structure-process (SSP) approaches similar to those discussed in this manuscript.,This study attempted to provide a robust conceptual framework to increase the understanding of the role of logistics/supply chain management strategy and provide insights to managers seeking to improve firm competitiveness. An essential implication of the conceptual model presented in this manuscript is the dynamics of logistics strategy as a competitive tool.,The findings provide an understanding of how business and manufacturing are operating in various locations in China with opportunities for employment and socio-economic gain among the population of these geographic locations. Having employment can provide a better quality of life and assist the community in developing its opportunities for other groups.,As the current Chinese administration seeks to achieve its goal of generating higher value-added production through its “Made in China 2025” initiative, the results the authors represent are quite timely and insightful. Examining manufacturing firms’ logistics strategies (i.e., OLS), coordination and customer service could provide state planners (SOEs) and/or privately owned Chinese manufacturers insights on how to move closer towards their aforementioned goal and achieve global competitiveness.

Population Resettlement for Hydropower Development in the Lancang River Basin: An Evolving Policy Framework and Its Implications for Local People

Hydropower is a crucial part of China’s energy portfolio and will remain key to reducing the country’s future reliance on fossil fuels. Yet hydropower dams cause the displacement of individuals and communities who live near them, affecting homes, employment, and farmland. Our focus in this chapter is on population displacement on the Lancang River, the upstream segment of the Mekong in China’s Yunnan Province and the Tibet Autonomous Region. We base our analysis on several data sources: household surveys undertaken with rural villagers near four of the Lancang River dam sites; analysis of government and industry reports on energy production and river basin management; analysis of government plans and procedures to compensate displaced people; and published reports on the Miaowei Hydropower Project, the first dam on the Lancang for which resettlement was undertaken according to the new 16118 policy, which provides long-term compensation and other benefits to resettled households. This allows us to analyse how resettlement undertaken under the new policy regime differs from earlier hydropower projects. Our findings suggest that while government and industry efforts to minimise harm to displaced communities are improving, more consideration is needed on social impacts, property rights, and policy implementation by local authorities.

Insight into the current practice of ototoxicity monitoring during cisplatin therapy

The aim of this study is to evaluate the current state of ototoxicity monitoring for patients receiving cisplatin chemotherapy in an academic medical center with particular attention to how closely monitoring adheres to national ototoxicity guidelines. Case series including retrospective medical records review of patients (age > 18) treated with cisplatin at University of California Davis Medical Center between January 2014 and August 2017. Patient and ototoxicity related variables were analyzed. Patients that underwent a transfer of care during treatment and with less than 3 months of follow-up were excluded. Three hundred seventy-nine patients met study criteria, of which 104 (27.4%) had a prior history of hearing loss. Prior to treatment, 196 (51.7%) patients were counseled regarding the ototoxic nature of cisplatin and 92 (24.3%) patients had a pretreatment audiogram. During treatment, 91 (24%) patients had documented otologic complaints. Only 17 patients (4.5%) patients had an audiogram ordered during their cisplatin treatment period. 130 (34.3%) patients had otologic complaints following cisplatin treatment. Audiograms were ordered for 20 (7.8%), 13 (5.1%), and 16 (6.2%) patients at 1-month, 3-month, and 6-month follow-ups, respectively. No patients in the study cohort received baseline, treatment, and post-treatment audiograms as recommended by national ototoxicity monitoring protocols. Patients with Head and Neck Cancer (HNC) represented the largest subgroup that received cisplatin (n = 122, 32.2%) and demonstrated higher rates of ototoxicity counseling (n = 103, 84.4%) and pretreatment audiograms (n = 70, 57.4%) compared to the non HNC group (n = 36, 36.2%, P < 0.0001 and n = 22, 8.5%, P < 0.0001). There is poor adherence to national ototoxicity monitoring guidelines at a large academic medical center. This is a missed opportunity for intervention and aural rehabilitation. Improved education and collaboration between otolaryngology, audiology, and medical oncology is needed to develop and promote an effective ototoxicity-monitoring program.

Collective resistance and organizational creativity amongst Europes platform workers: a new power in the labour movement?

This chapter makes the argument that labour agency in the platform economy in Europe has given rise to a plethora of new informal and formal organisations for mutual aid and worker representation. This organisational experimentation is commonly initially based on digital online communities. Their further offline development is rather uneven, however, as it is informed by the type of platform work the workers engage in and the power resources available to them (or simply because the current structure is efficient enough for fulfilling the platform workers’ purposes). Nevertheless, these bottom-up initiatives point to recurrent patterns in labour-capital dynamics. Some new organisations, in terms of scale, structure or development, recall the kinds of worker organisations that appeared at the end of the nineteenth century. Most but not all of these new organisations have oriented themselves towards a logic-of-membership approach. In many instances, this approach might be complementary with the logic-of-influence approach favoured by today’s mainstream trade unions. Building alliances between the ‘new’ and ‘old’ could reinforce the countervailing power of platform workers and their struggle for regulatory change in the platform economy.
ARBITRAGE AND CONVERGENCE: EVIDENCE FROM MEXICAN ADRS

This paper investigates the convergence between the prices of ADRs and Mexican traded shares using a sample of 21 dually listed shares. Since both markets have similar trading hours, standard arbitrage considerations should make persistent deviation from price parity rare. We use a STAR model, where the dynamics of convergence to price parity are influenced by the size of the deviation from price parity. Based on different tests, we select the ESTAR model. Deviations from price parity tend to die out quickly; for 14 out of 21 pairs it takes less than two days for the deviations from price parity to be reduced by half. The average half-life of a shock to price parity is 3.1 business days, while the median half-life is 1.1 business days. By allowing a non-linear adjustment process, the average half-life is reduced by more than 50% when compared to the standard linear arbitrage model. We find that several liquidity indicators are positively correlated to the speed of convergence to price parity.
Prior health care utilization among adolescents treated for a suicide attempt at a rural ED.

PURPOSE To characterize prior contact with a rural academic health system among young people treated for a suicide attempt in the system's emergency departments (EDs). METHODS We retrospectively examined electronic medical records from a health system serving 29 medically underserved rural counties in the Southeastern United States. Patients ages 10-25 years were included in the study if they were admitted to the ED for a suicide attempt in 2015-2018. Patients were stratified according to whether they had any encounter in the same health system in the 12 months prior to the attempt. FINDINGS Of 236 patients meeting inclusion criteria, only 10% had contact with the health system in the 12 months prior to ED treatment for a suicide attempt. Patients who lived farther than 25 km from the flagship hospital were less likely to have had prior contact (odds ratio [OR]: 0.10, 95% confidence interval [CI]: 0.02-0.34). Young adults ages 19-25 years were also less likely to have prior contact than adolescents (OR: 0.27, 95% CI: 0.08-0.76). CONCLUSIONS Few adolescents and young adults in this rural region received prior health care from the same health system where they were treated for a suicide attempt. Hospitals operating in rural areas need to partner with community health care providers to ensure adequate reach of screening and treatment programs to prevent youth suicide and reduce care fragmentation.
Computer control of a robotic satellite servicer

The advantages that will accrue from the in-orbit servicing of satellites are listed. It is noted that in a concept in satellite servicing which holds promise as a compromise between the high flexibility and adaptability of manned vehicles and the lower cost of an unmanned vehicle involves an unmanned servicer carrying a remotely supervised robotic manipulator arm. Because of deficiencies in sensor technology, robot servicing would require that satellites be designed according to a modular concept. A description is given of the servicer simulation hardware, the computer and interface hardware, and the software. It is noted that several areas require further development; these include automated docking, modularization of satellite design, reliable connector and latching mechanisms, development of manipulators for space environments, and development of automated diagnostic techniques.
Assessing the effects of parent-child interactions on child communication skills

This study examined the role maternal and child characteristics play in children’s subsequent communication development. The relationship between parent-child interactions and child communications skills was examined using the Indicator of Parent-Child Interactions (IPCI) and the Early Communication Indicator (ECI). Twenty-two mother-child dyads were assessed at three time points. Children ranged in age from 7 months to 30 months at the start of the study. Significant concurrent relationships were found between child engagement behaviors and total communication scores at time 1 and 3. A significant negative concurrent correlation existed between child reactivity behaviors and total communication scores at time 1. No significant predictive relationships were found. The IPCI total percentage scores at time 1 did not predict ECI total communication scores at time 2 or 3. The need for future research and implications for the field of parent-child interactions are discussed.
A UNIFIED CORPS OF ADMINISTRATIVE LAW JUDGES—THE TRANSITION FROM A CONCEPT TO AN EVENTUAL REALITY

The concept of a unified corps of federal administrative law judges began to be generally recognized approximately ten years ago. The concept was simple. Transfer approximately 1100 judges from twenty-nine different federal agencies into a single entity. The principal reasons advanced for such a change were to insure judicial independence and to provide significant efficencies and cost savings. Although there was a substantial body of literature available on the subject,l no document actually provided the specific details of a unified corps for the federal government. What kind of structure would be involved? How would such an entity be managed? How would the expertise of judges at various agencies be preserved? What impact would a unified corps have on the authority of the agencies? These were just some of the many questions that came to mind. But there were few precise answers. One thing was apparent; there was overwhelming support for the concept within the adminis­ trative law judge community. It was seen as a significant reform of
Far-UV Spectral Variability in UM425 & PG1115+080

Determining the nature of spectral variability in gravitationally-lensed BAL (broad absorption line) quasars is important for time-delay and microlensing studies because the delay-times can be comparable with the time scales of intrinsic QSO ionization changes. Far-UV spectra of the candidate lens UM 425 = Ql120+019A and PG1115+080A (Triple Quasar) revealed the presence of strong O VI λ1033 emission. In both cases, absorption in the blue-wing of the O VI line profile indicated characteristic BAL outflow.
Predictions of the Pt 8 Ti phase in unexpected systems

The binary A8B phase (prototype Pt8Ti) has been experimentally observed in 11 systems. A high-throughput search over all the binary transition intermetallics, however, reveals 59 occurrences of the A8B phase: Au8Zn†, Cd8Sc†, Cu8Ni†, Cu8Zn†, Hg8La, Ir8Os†, Ir8Re, Ir8Ru†, Ir8Tc, Ir8W†, Nb8Os†, Nb8Rh†, Nb8Ru†, Nb8Ta†, Ni8Fe, Ni8Mo†*, Ni8Nb†*, Ni8Ta*, Ni8V*, Ni8W, Pd8Al†, Pd8Fe, Pd8Hf, Pd8Mn, Pd8Mo*, Pd8Nb, Pd8Sc, Pd8Ta, Pd8Ti, Pd8V*, Pd8W*, Pd8Zn, Pd8Zr, Pt8Al†, Pt8Cr*, Pt8Hf, Pt8Mn, Pt8Mo, Pt8Nb, Pt8Rh†, Pt8Sc, Pt8Ta, Pt8Ti*, Pt8V*, Pt8W, Pt8Zr*, Rh8Mo, Rh8W, Ta8Pd, Ta8Pt, Ta8Rh, V8Cr†, V8Fe†, V8Ir†, V8Ni†, V8Pd, V8Pt, V8Rh, and V8Ru† († = metastable, * = experimentally observed). This is surprising for the wealth of new occurrences that are predicted, especially in well-characterized systems (e.g., Cu−Zn). By verifying all experimental results while offering additional predictions, our study serves as a striking demonstration of the power of the high-throughput approach. The practicality of the method is d...
Differential detergent-solubilization of integral thylakoid membrane complexes in spinach chloroplasts. Localization of photosystem II, cytochrome b6-f complex and photosystem I.

Progressive solubilization of spinach chloroplast thylakoids by Triton X-100 was employed to investigate the domain organization of the electron transport complexes in the thylakoid membrane. Triton/chlorophyll ratios of 1:1 were sufficient to disrupt fully the continuity of the thylakoid membrane network, but not sufficient to solubilize either photosystem I (PSI), photosystem II (PSII) or the cytochrome b6-f (Cyt b6-f) complex. Progressive with the Triton concentration increase (Triton/Chl >1:1), a differential solubilization of the three electron transport complexes was observed. (a) Solubilization of the Cyt b6-f complex from the thylakoid membrane preceded that of PSI and apparently occurred early in the solubilization of stroma-exposed segments of the chloroplast lamellae. (b) The initial removal of chlorophyll (up to 40% of the total) occurred upon solubilization of PSI from the stroma-exposed lamella regions in which PSI is localized. (c) The tightly appressed membrane of the grana partition regions was markedly resistant to solubilization by Triton X-100. Thus, solubilization of PSII from this membrane region was initiated only after all Cyt b6-f and PSI complexes were removed from the chloroplast lamellae. The results support the notion of extreme lateral heterogeneity in the organization of the electron transport complexes in higher plant chloroplasts and suggest a Cyt b6-f localization in the membrane of the narrow fret regions which serve as a continum between the grana and stroma lamellae.
Correct interpretation of trace normalized density matrices as ensembles

A density operator, $\rho = {P}_{\alpha } |\alpha > = 0$, ${P}_{\alpha }$ and ${P}_{\beta }$ cannot be interpreted as probabilities of finding $|\alpha >$ and $|\beta >$ respectively. We show that a density matrix comprised of two (${P}_{\alpha }$ and ${P}_{\beta }$ nonzero) non-orthogonal projectors have unique spectral decomposition into diagonal form with orthogonal projectors. Only then, according to axioms of Von Neumann and Fock, can we have probability interpretation of that density matrix, only then can the diagonal elements be interpreted as probabilities of an ensemble. Those probabilities on the diagonal are not ${P}_{\alpha }$ and ${P}_{\beta}$. Further, only in the case of orthogonal projectors can we have the degenerate situation in which multiple ensembles are permitted.
Corrosion susceptibility of Al-Cu and Al-Cu-Si films

The susceptibility to chlorine-induced corrosion of Al-Cu and Al-Cu-Si films has been measured. The adverse impact of Cu on the corrosion susceptibility of unsintered films is clearly evident at 0.3% and increases sharply between 1.0% and 2.0% with the latter being 6 times more corrosive than the former. Adding 1.0% Si to the Al-Cu (2%) alloys tends to lower the corrosion susceptibility of unannealed films by a factor of 9. This effect is shown to be caused by higher quality native aluminum oxide resulting in a delay in the onset of the corrosion rather than a slower rate once corrosion has begun. Annealing (30 min at 450 degrees C) the copper containing films also has a beneficial effect on corrosion susceptibility. >
A revolution in classical scholarship

In a review ( JHS lxxxvi [1966] 205 f.) of P. A. Stadter's Plutarch's historical methods: an analysis of the Mulierum virtutes (Cambridge, Mass.: Harvard University Press, 1965), Mr T. F. Carney, who was at that time Fulbright Visiting Scholar in the Department of Political Science of the Massachusetts Institute of Technology, claimed that the book ‘analyses somewhat dated problems with only partially up-dated tools’ and that the ‘actual findings of the book replicate what is already known’. Although Mr Carney takes it for granted that his readers know what the ‘up-dated tools’ are, at the end of his review he drops the key words ‘content analysis’, in which, according to him, Stadter had engaged unwittingly, but obviously without success. Inasmuch as the book in question grew out of a dissertation suggested and directed by this writer, it may perhaps be allowed to reply to the rather serious charges raised in this review, charges which are unprecedented in the history of this Journal and which, if they were justified, could have far-reaching implications. This writer must confess that he was first baffled both by the degree of hostility displayed and by the criticisms, which, though specific, are often murky; but he was baffled even more by the general accusation of ‘only partially up-dated tools’ and inappropriate use of ‘content analysis’, a term he had never previously encountered. But this writer soon found out that content analysis is ‘a research tool in mass communication’ (R. W. Butt and R. K. Thorp, An Introduction to Content Analysis [A Publication of the University of Iowa School of Journalism, Iowa City, Iowa, 1963] 1), ‘a research technique for the objective, systematic, and quantitative description of the manifest content of communication’ (Bernard Berelson, Content Analysis in Communication Research [The Free Press, Glencoe, Illinois, 1952] 18 [still the chief book in the field]); and it became clear that Mr Carney wore the social scientist's hat when he wrote his review.

Multi-task learning for sequential data via iHMMs and the nested Dirichlet process

A new hierarchical nonparametric Bayesian model is proposed for the problem of multitask learning (MTL) with sequential data. Sequential data are typically modeled with a hidden Markov model (HMM), for which one often must choose an appropriate model structure (number of states) before learning. Here we model sequential data from each task with an infinite hidden Markov model (iHMM), avoiding the problem of model selection. The MTL for iHMMs is implemented by imposing a nested Dirichlet process (nDP) prior on the base distributions of the iHMMs. The nDP-iHMM MTL method allows us to perform task-level clustering and data-level clustering simultaneously, with which the learning for individual iHMMs is enhanced and between-task similarities are learned. Learning and inference for the nDP-iHMM MTL are based on a Gibbs sampler. The effectiveness of the framework is demonstrated using synthetic data as well as real music data.
Leadership experience and leader performance—another hypothesis shot to hell☆

Abstract Data from three experiments and 385 managers and supervisors of task groups in five different organizations were used to test the hypothesis that number of years of supervisory experience will correlate positively with leadership performance as measured by group productivity. None of the experimental tests, and none of the seven field studies supported this hypothesis. In fact, the median correlation for independent samples between years of supervisory experience and leadership performance was — .12. These results are discussed in terms of their implications for leadership theory and management selection practices.
Multi-area optimal power flow with changeable transmission topology

This study presents a framework for coordinating multi-area optimal power flow with adjustable network topology in an electric power system. The modelling is accomplished in a coordinated but not a centralised fashion. Each regional operator dispatches its own generation and switches its own transmission network to reach its optimal benefits. The proposed model uses augmented Lagrangian relaxation to realise decomposition. No other information is exchanged between the regional operators except the Lagrangian multipliers. This study compares the centralised transmission switching model and the proposed decentralised method by using several numerical tests. The results verify the effectiveness of the solution methodology. The decomposition framework proposed in this study can serve as a foundation for implementing parallel computing.
Physisorption Kinetics in Carbon Nanotube Bundles

The kinetics of gas uptake on different regions of carbon nanotube bundles is investigated by means of a kinetic Monte Carlo scheme. A lattice-gas description is used to model the adsorption of particles on a one-dimensional chain of sites under two types of dynamics: (a) external kinetics, in which the chain is on the bundle's external surface directly exposed to the gas, and (b) pore-like kinetics, expected to occur inside the tubes and interstitial channels, where adsorption occurs via gas diffusion from the ends. From the time evolution of the coverage at a fixed temperature, equilibration times are obtained as a function of chemical potential (or amount adsorbed). The equilibration time of the external phase decreases linearly as the coverage increases toward monolayer completion; the rate at which this occurs strongly depends on the ratio between the binding energy and the temperature. Because of this dependence, unexpectedly long waiting times can be observed for very low coverages in systems with...
CDK14 expression is down-regulated by cigarette smoke in vivo and in vitro

In this study, DNA arrays have been employed to monitor gene expression patterns in testis of mice exposed to tobacco smoke for 24 weeks and compared to control animals. The results of the analysis revealed significant changes in expression of several genes that may have a role in spermatogenesis. Cdk14 was chosen for further characterization because of a suggested role in the testis and in regulation of Wnt signaling. RT-PCR analysis confirmed down regulation of Cdk14 in mice exposed to cigarette smoke (CS). Cdk14 is expressed in all testicular cells; spermatogonia- and Sertoli-derived cell lines treated with cigarette smoke extract (CSE) in vitro showed down-regulation of CDK14 mRNA and protein levels as well as down-regulation of β-catenin levels. CS-induced down-regulation of CDK14 mRNA and protein levels was also observed in several lung epithelium-derived cell lines including primary normal human bronchial epithelial cells (NHBE), suggesting that the effect is not restricted to the testis. Similar to testicular cells, CS-induced down-regulation of CDK14 in lung cells correlated with decreased levels of β-catenin, a finding suggesting impaired Wnt signaling. In the lungs, CDK14 was localized to the alveolar and bronchial epithelium.
Prostatic structure and function in relation to the etiology of prostatic cancer

In this paper, studies by a large series of independent investigators are reviewed with regard to the basic structure and function of the prostate in an attempt to examine their relationship to prostatic cancer etiology. These studies demonstrate that the functional activities of the prostate involve secretion, transport, and reabsorption of a variety of materials into and out of the glandular lumen and that these activities are directly related to the basic structural organization of the gland. These functional activities are constantly occurring in the prostate even under basal (ie, nonejaculating) conditions. Due to these functional activities, the prostatic fluid in the glandular lumen is a complex mixture of a variety of components derived, not only from the synthetic activity of the glandular epithelial cells of the gland itself, but also from the blood serum. The levels of these components are continuously modulated, not only by the frequency of active ejaculation, but also, under basal conditions by the continuous interaction with the glandular prostatic cells lining the acinar lumen and ducts. A concept is presented that the initiation and/or promotion of prostatic carcinogenesis may well involve the chronic modulation/interaction of the prostatic glandular cells with their lumenal fluid.
