FIB-Assisted Fabrication of Single Tellurium Nanotube Based High Performance Photodetector

Nanoscale tellurium (Te) materials are promising for advanced optoelectronics owing to their outstanding photoelectrical properties. In this work, high-performance optoelectronic nanodevice based on a single tellurium nanotube (NT) was prepared by focused ion beam (FIB)-assisted technique. The individual Te NT photodetector demonstrates a high photoresponsivity of 1.65 × 104 AW−1 and a high photoconductivity gain of 5.0 × 106%, which shows great promise for further optoelectronic device applications.
An Analysis of Human Risk Taking in Simulated Occupational Situations

Human risk-taking in simulated occupational situations containing personal injury as a hazard was investigated. The occupational situations of interest are those requiring manual interaction with active machine components within given time constraints. The results of three studies are presented with emphasis on the third study. The first two investigated the relationship between selected personal attributes and subjects1 risk-taking tendencies as described by the maximum probability of failure under which they would accept a risk. The variables of interest in the first study were principally perceptual-motor skills. The second study was directed at the question: Do introverts and extraverts differ in the amount of risk they are willing to take relative to their abilities, and if so, what causes the difference? In the third study, subjects worked in pairs, (one the decision maker, one the performer) under eight conditions of potential gain or loss. Comparisons were made of the risks subjects selected for themselves and the other person. Personality factors which may influence decision making were measured.
The Effect of Using a New Parameterization of Nucleation in the WRF-Chem Model on New Particle Formation in a Passive Volcanic Plume

We investigated the role of the passive volcanic plume of Mount Etna (Italy) in the formation of new particles in the size range of 2.5–10 nm through the gas-to-particle nucleation of sulfuric acid (H2SO4) precursors, formed from the oxidation of SO2, and their evolution to particles with diameters larger than 100 nm. Two simulations were performed using the Weather Research and Forecasting Model coupled with chemistry (WRF-Chem) under the same configuration, except for the nucleation parameterization implemented in the model: the activation nucleation parameterization (JS1 = 2.0 × 10−6 × (H2SO4)) in the first simulation (S1) and a new parameterization for nucleation (NPN) (JS2 = 1.844 × 10−8 × (H2SO4)1.12) in the second simulation (S2). The comparison of the numerical results with the observations shows that, on average, NPN improves the performance of the model in the prediction of the H2SO4 concentrations, newly-formed particles (~2.5–10 nm), and their growth into larger particles (10–100 nm) by decreasing the rates of H2SO4 consumption and nucleation relative to S1. In addition, particles formed in the plume do not grow into cloud condensation nuclei (CCN) sizes (100–215 nm) within a few hours of the vent (tens of km). However, tracking the size evolution of simulated particles along the passive plume indicates the downwind formation of particles larger than 100 nm more than 100 km far from the vent with relatively high concentrations relative to the background (more than 1500 cm−3) in S2. These particles, originating in the volcanic source, could affect the chemical and microphysical properties of clouds and exert regional climatic effects over time.
New cell biological explanations for kinesin-linked axon degeneration

Axons are the slender, up to meter-long projections of neurons that form the biological cables wiring our bodies. Most of these delicate structures must survive for an organism’s lifetime, meaning up to a century in humans. Axon maintenance requires life-sustaining motor protein-driven transport distributing materials and organelles from the distant cell body. It seems logic that impairing this transport causes systemic deprivation linking to axon degeneration. But the key steps underlying these pathological processes are little understood. To investigate mechanisms triggered by motor protein aberrations, we studied more than 40 loss- and gain-of-function conditions of motor proteins, cargo linkers or further genes involved in related processes of cellular physiology. We used one standardised Drosophila primary neuron system and focussed on the organisation of axonal microtubule bundles as an easy to assess readout reflecting axon integrity. We found that bundle disintegration into curled microtubules is caused by the losses of Dynein heavy chain and the Kif1 and Kif5 homologues Unc-104 and Kinesin heavy chain (Khc). Using point mutations of Khc and functional loss of its linker proteins, we studied which of Khc’s sub-functions might link to microtubule curling. One cause was emergence of harmful reactive oxygen species through loss of Milton/Miro-mediated mitochondrial transport. In contrast, loss of the Kinesin light chain linker caused microtubule curling through an entirely different mechanism appearing to involve increased mechanical challenge to microtubule bundles through de-inhibition of Khc. The wider implications of our findings for the understanding of axon maintenance and pathology are discussed.
An algorithm for parallel unstructured mesh generation and flow analysis

A strategy for the parallel generation of unstructured meshes is proposed. A distributed unstructured mesh generation environment is presented and this is coupled with a time dependent compressible Navier-Stokes equations solver. The mesh generation schemes developed in the serial context are extended for parallel execution. Dynamic load-balancing and mesh migration are incorporated to ensure even work distribution and for refinement analysis. Anisotropic mesh refinement is also incorporated for flow analysis involving anisotropic gradients. The flow solver is linked to the mesh generation environment as a test of the parallel mesh generation capabilities for flow analysis and several well defined test cases are modeled for comparison to experimental results.
Assessing the effects of track input on the response of insulated rail joints using field experiments

Manufacturers of insulated rail joints (IRJs) have to follow the quality assurance regime stipulated in the national design standards; unfortunately, IRJs still exhibit a very low and highly variable service life. It is widely believed that the service life of IRJs is affected by the track input under the passage of loaded wheels; however, there is a paucity of literature with regard to the actual mechanical behaviour of IRJs in the track. An extensive field test was, therefore, conducted on an in-service heavy haul corridor in Australia with the specific aim of understanding the effect of the track input on the response of the IRJs. Data on the wheel–rail force, rail/joint-bar strain, sleeper acceleration and ballast pressure signatures in the time domain were determined from the experiment. This data was subsequently systematically analysed to compare the relative structural merits of two IRJs resting on different sleeper spaces and a reference continuous rail subjected to similar real-life coal traffic loading.
CHANGES IN MACRONUTRIENTS AND PHYSICAL PROPERTIES DURING THE GROWTH OF Lentinula edodes AND Pleurotus ostreatus IN A COMPOST BASED ON SUGARCANE BAGASSE AGRICULTURAL WASTE

Spent mushroom substrate of different edible mushrooms is a nutrient-rich biomass associated with mycelial metabolic activity in the growth substrate. The objective of this study was to evaluate the changes in the nutritional content and physical properties of a sugarcane bagasse substrate after the cultivation of the edible mushrooms Pleurotus ostreatus and Lentinula edodes . Strains of both species were first propagated in potato dextrose agar culture medium, then in wheat grains, and finally inoculated in sterile sugarcane bagasse. Determinations of macronutrients, pH and C:N ratio were carried out at 0, 30 and 60 days after mushroom mycelium growth in the bagasse-based substrate. After 30 and 60 days of inoculation, nitrogen (N), phosphorous (P) and potassium (K) recorded increases of 0.26%, 0.06% and 0.14 with Pleurotus ostreatus, and increases of 0.33%, 0.05%, and 0.11% with Lentinula edodes, respectively. Regarding micronutrients, there was an increase in Calcium (Ca) and Sulphur (S) in both substrates, but amounts varied during the time evaluated. Additionally, an important increase in hydrogen ion concentration was observed when both species were inoculated, with final values of 4.26 and 3.9 for Pleurotus ostreatus and Lentinula edodes species, respectively. In conclusion, this biomass presents a high percentage of the essential micro and macro elements required in a fertilizer.
Design of a Novel Fault Tolerant Reversible Montgomery Multiplier in Nanotechnology

Reversible logic has received great attention in recent years due to its ability to reduce the power dissipation which is the main requirement in low power VLSI design (Kocher, 1999). It has many applications in low power CMOS Design, quantum computing, DNA computing, bioinformatics, and nanotechnology. Low power consumption is a major issue in VLSI circuits today. This paper proposes fault tolerant reversible Montgomery multiplier for the first time. The proposed fault tolerant reversible multiplier circuit can multiply two n-bit binary numbers. This paper deals with fault tolerant for binary reversible circuits. The proposed circuits can be used to construct a more complex system in nanotechnology.
Evaluation of Compression Behaviors of Marine Clay Reinforced with Waste Shredded Tires

This study evaluates the compression behaviors of a soft marine clay reinforced with waste shredded tire (WST) at different sizes (<0.5 mm, 0.5–2.0 mm, and 2.0–4.0 mm) and contents (15%, 35%, and 50%). Results from compression tests indicate that the compression index (Cc) of WST-reinforced soft clay decreases with increasing WST shred size and content. The swelling index (Cs) increases as the WST shred size and content increase. The difference in compression curves becomes more significant for composite reinforced at large shred size. The void indexes of WST-reinforced Lianyungang clay can be well normalized regardless of WST shred size and content by a regression line. The WST dominates the compression behavior of the WST-clay composite, as the WST would be compressed prior to the clay particles. The results in this study provide an optimum WST content at 50% with shred size of 2.0–4.0 mm for reinforcing the Lianyungang marine clay for achieving higher compressibility, contributing to the input database of machine learning for WST-reinforced soil.
Training and Research on Probabilistic Hydro-Thermo-Mechanical Modeling of Carbon Dioxide Geological Sequestration in Fractured Porous Rocks

Colorado School of Mines conducted research and training in the development and validation of an advanced CO{sub 2} GS (Geological Sequestration) probabilistic simulation and risk assessment model. CO{sub 2} GS simulation and risk assessment is used to develop advanced numerical simulation models of the subsurface to forecast CO2 behavior and transport; optimize site operational practices; ensure site safety; and refine site monitoring, verification, and accounting efforts. As simulation models are refined with new data, the uncertainty surrounding the identified risks decrease, thereby providing more accurate risk assessment. The models considered the full coupling of multiple physical processes (geomechanical and fluid flow) and describe the effects of stochastic hydro-mechanical (H-M) parameters on the modeling of CO{sub 2} flow and transport in fractured porous rocks. Graduate students were involved in the development and validation of the model that can be used to predict the fate, movement, and storage of CO{sub 2} in subsurface formations, and to evaluate the risk of potential leakage to the atmosphere and underground aquifers. The main major contributions from the project include the development of: 1) an improved procedure to rigorously couple the simulations of hydro-thermomechanical (H-M) processes involved in CO{sub 2} GS; 2) models for the hydro-mechanicalmore » behavior of fractured porous rocks with random fracture patterns; and 3) probabilistic methods to account for the effects of stochastic fluid flow and geomechanical properties on flow, transport, storage and leakage associated with CO{sub 2} GS. The research project provided the means to educate and train graduate students in the science and technology of CO{sub 2} GS, with a focus on geologic storage. Specifically, the training included the investigation of an advanced CO{sub 2} GS simulation and risk assessment model that can be used to predict the fate, movement, and storage of CO{sub 2} in underground formations, and the evaluation of the risk of potential CO{sub 2} leakage to the atmosphere and underground aquifers. « less
Authentic leadership style and its implications in project management

Project leader/manager is vital for project management organization. Project manager should be able to influence the followers positively, manage several activities together, communicate with various stakeholders at the same time, manage conflicts, take difficult and risky decisions, deal with several socio-economic and cultural challenges, handle several deadlines, control the resources, solve disputes, and finally achieve the project objectives. To accomplish these jobs, the project leader must develop an appropriate leadership style which can be employed under such circumstances for effective performance outcomes. Moreover, leadership researchers have argued that current frameworks do not suffice the need to develop future leaders who can face the challenging future with valor. This situation necessitates the need for a new form of leadership. This paper presents a case for changing and more demanding role of project leader for managing the exigent future projects. The authors argue that a new breed and generation of project leaders is required to fight the turbulent business environment. This new leadership can be provided by developing authentic leadership style in project leaders. It is argued that authentic leadership style is unique and best suited to project management practices. The paper also discusses benefits and applications of authentic leadership style in project management. Proposals are made for authentic leadership development in project leaders. The study would be beneficial for management professionals in the business industry in general.
All-cause mortality rates in adults with carbapenem-resistant Gram-negative bacterial infections: a comprehensive review of pathogen-focused, prospective, randomized, interventional clinical studies

ABSTRACT Introduction Pathogen-focused, randomized, controlled trials (PF-RCT) are important in the fight against carbapenem-resistant (CR) Gram-negative infections. Some recently approved antibiotics and older generic antibiotics with activity against CR Gram-negative bacteria were investigated in PF-RCTs in a variety of infections. Areas covered We searched Pubmed, Cochrane database and international clinical trial databases for PF-RCTs for the period between 2005 and 2020 and compared the study designs, patient populations, infection types, pathogens, and Day-28 all-cause mortality (ACM). Expert opinion PF-RCTs are particularly challenging to quantitatively assess and compare due to the heterogeneity in infection types, pathogens, CR mechanism, inclusion/exclusion criteria, and endpoints. Data interpretation is further complicated by lack of formal statistical analysis plans and/or non-inferiority design, and limited power across most PF-RCTs. The studies with new antibiotics (i.e. plazomicin, meropenem/vaborbactam, cefiderocol) ranked lower regarding feasibility, with relatively small sample sizes (analyzed: 37–118) versus the comparative effectiveness studies of older generic drugs (analyzed: 94–406). ACM ranged between 11.8% and 40% for CR Enterobacterales, 17.7% and 57.4% for CR Acinetobacter spp. , and 20.0% and 30.8% for CR Pseudomonas aeruginosa. The information gathered must be considered carefully alongside the study limitations and caution should be exercised when making direct comparisons across trials. PLAIN LANGUAGE SUMMARY New antibiotics to treat multidrug-resistant Gram-negative bacterial infections are needed because antimicrobial resistance has become a global threat. In recent years, several pathogen-focused, randomized, controlled clinical trials were conducted to test new antibiotics or combinations of older generic antibiotics in the fight against resistant bacteria. However, these trials were exceptionally challenging and most of them enrolled relatively few patients. These studies were highly heterogeneous in terms of species, antibiotics, infection site, mechanism of resistance, endpoints and patient factors. In these trials, all-cause mortality at Day 28 or Day 30 were numerically lower with the new antibiotics in infections caused by carbapenem-resistant (CR) Enterobacterales. However, in the trials which investigated CR Acinetobacter spp. infections, there was no reduction in all-cause mortality at Day 28 or Day 30 with combinations of older generic antibiotics compared with colistin monotherapy. Limited information was available for CR Pseudomonas aeruginosa. More pathogen-focused, randomized, controlled clinical trials with more feasible design and higher patient numbers are needed to demonstrate clinical benefit in drug-resistant infections.
Stopping the legal flow of weapons

This article examines sending state compliance with arms embargoes. Arms embargoes are one of the most frequently used types of economic sanctions but they are perceived as one of the least effective. One major problem with arms embargoes, many argue, is sending states’ failure to implement them. Yet studies tend to focus on cases of arms embargo violations, not compliance in the context of arms export practice more broadly. Using a series of new arms embargo variables, I conduct a statistical analysis of the relationship between arms embargoes and small and major conventional arms transfers from 1981 to 2004. Contrary to popular expectations, I find that arms embargoes on average restrain sending states’ arms exports. If arms embargoes do indeed have difficulty changing targets’ behavior, or achieving other measures of ‘success’, additional explanations must also be considered. I suggest that arms embargo target selection and the intractable challenge of cutting off illicit arms flows are two important plausible alternatives. This finding also provides optimism for compliance with international commitments in the absence of institutionalized enforcement mechanisms. Major exporters overall appear to implement sanctions, despite strong economic incentives to ignore them and a lack of formal accountability mechanisms to punish violators.
Characteristics of Clear Cell Papillary Renal Cell Carcinoma (ccpRCC)

Renal cell carcinomas (RCCs) is a group of various malignant tumours of the renal cortex displaying distinct clinical, morphologic, and genetic features. Clear cell papillary renal cell carcinoma (ccpRCC), belonging to this group, shares morphologic features with both clear cell renal cell carcinoma (ccRCC) and papillary renal cell carcinoma (pRCC) and therefore, more strict diagnostic criteria should be developed to avoid misdiagnosis. Despite overlapping features, ccpRCC has also distinct clinical behaviour, histologic characteristics (morphologic and immunohistochemical), and genomic features. The concepts concerning this tumour are constantly developing since its biological potential and molecular basis remains to be fully unravelled. First reports indicated the presence of ccpRCC in end-stage renal disease, and they underlined the enriched development in this group of patients; however, currently, it is known that such tumours can also occur spontaneously in the normal kidney. Numerous studies have demonstrated that clinical outcomes and prognosis of ccpRCC patients is highly favourable. Till now, no convincing evidence of metastatic ccpRCC or death caused by the disease has been found. Therefore, it is of high importance to correctly differentiate ccpRCC from other subtypes of RCC with a much worse prognosis and to introduce appropriate management.
Fractional order intensity measures for probabilistic seismic demand modeling applied to highway bridges

Probabilistic seismic analysis of structures involves the construction of seismic demand models, often stated as probabilistic models of structural response conditioned on a seismic intensity measure. The uncertainty introduced by the model is often a result of the chosen intensity measure. This paper introduces the concept of using fractional order intensity measures (IMs) in probabilistic seismic demand analysis and uses a single frame integral concrete box‐girder bridge class and a seismically designed multispan continuous steel girder bridge class as case studies. The fractional order IMs considered include peak ground response and spectral accelerations at 0.2 and 1.0 s considering a single degree of freedom system with fractional damping, Sad−Tnα , as well as a linear single degree of freedom system with fractional response, Sar−Tnα . The study reveals the advantage of fractional order IMs relative to conventional IMs such as peak ground acceleration, peak ground velocity, or spectral acceleration at 0.2 and 1.0 s. Metrics such as efficiency, sufficiency, practicality, and proficiency are measured to assess the optimal nature of fractional order IMs. The results indicate that the proposed fractional order IMs produce significant improvements in efficiency and proficiency, whereas maintaining practicality and sufficiency, and thus providing superior demand models that can be used in probabilistic seismic demand analysis.

RESEARCH DESIGN AND METHODSdWe used two cohort studies with the same source of database to determine the link between depression and type 2 diabetes. The data analyzed included a random sample of 1 million beneficiaries selected from the National Health Insurance claims in 2000. The analysis of diabetes predicting the depression onset consisted of 16,957 diabetic patients and the same number of sexand age-matched nondiabetic control subjects. The analysis of depression predicting diabetes onset included 5,847 depressive patients and 5,847 sexand age-matched nondepressive control subjects. The follow-up period was between 2000 and 2006, and onset of end points was identified from ambulatory care claims. The Cox proportional hazards regression model adjusted for potential confounders was used to estimate relative hazards.
A New Dataset for Measuring Democracy, 1810-1998

Democracy has been defined and measured in various ways. This article argues that combining two basic dimensions of democracy - competition and participation - can yield a theoretically satisfactory measurement of democracy that employs three measures: degree of electoral competition, degree of electoral participation and a combined index of democratization. These variables have been used in the author's previous comparative studies of democracy. The new dataset combines previous data and extends these to cover the period 1810-1998. That dataset includes 187 contemporary and former independent states from the year 1810 or from the year of independence. In the dataset, original electoral and other political data needed to calculate the values of Competition and Participation variables are given and documented separately for each country. The values of the three variables are calculated and given for each year over the period of comparison. Finally, the new dataset is compared with the Polity98 measures of democracy and the combined Freedom House ratings of political rights and civil liberties.
