Evaluation of Different Projectiles in Matched Experimental Eye Impact Simulations (2011)

Eye trauma results in 30,000 cases of blindness each year in the United States and is the second leading cause of monocular visual impairment. Eye injury is caused by a wide variety of projectile impacts and loading scenarios with common sources of trauma being motor vehicle crashes, military operations, and sporting impacts. For the current study, 79 experimental eye impact tests in literature were computationally modeled to analyze global and localized responses of the eye to a variety of blunt projectile impacts. Simulations were run with eight different projectiles (airsoft pellets, baseball, air gun pellets commonly known as BBs, blunt impactor, paintball, aluminum, foam, and plastic rods) to characterize effects of the projectile size, mass, geometry, material properties, and velocity on eye response. This study presents a matched comparison of experimental test results and computational model outputs including stress, energy, and pressure used to evaluate risk of eye injury. In general, the computational results agreed with the experimental results. A receiver operating characteristic curve analysis was used to establish the stress and pressure thresholds that best discriminated for globe rupture in the matched experimental tests. Globe rupture is predicted by the computational simulations when the corneoscleral stress exceeds 17.21 MPa or the vitreous pressure exceeds 1.01 MPa. Peak stresses were located at the apex of the cornea, the limbus, or the equator depending on the type of projectile impacting the eye. A multivariate correlation analysis revealed that area-normalized kinetic energy was the best single predictor of peak stress and pressure. Additional incorporation of a relative size parameter that relates the projectile area to the area of the eye reduced stress response variability and may be of importance in eye injury prediction. The modeling efforts shed light on the injury response of the eye when subjected to a variety of blunt projectile impacts and further validate the eye model's ability to predict globe rupture. Results of this study are relevant to the design and regulation of safety systems and equipment to protect against eye injury.
Back Cover: Titanium(IV) in the Organic‐Structure‐Directing‐Agent‐Free Synthesis of Hydrophobic and Large‐Pore Molecular Sieves as Redox Catalysts (ChemSusChem 15/2015) (2015)

The Back Cover picture shows two different synthetic routes to prepare microporous titanosilicate molecular sieves. One is a traditional route that requires expensive organic molecules used as organic structure-directing agents (OSDA, right), whereas the other one is a newly developed OSDA-free route that does not require any organic molecules (left). The absence of an organic template in the synthesis could avoid environmental problems as pyrolysis of the organic template in the traditional route generates toxic gases such as CO2 and NOx. Moreover, titanosilicate molecular sieves prepared using the OSDA-free route show considerably higher catalytic activity for the epoxidation of bulky cyclooctene with H2O2. More details can be found in the Communication by Y. Zhao et al. on page 2476 in Issue 15, 2015. (DOI: 10.1002/cssc.201500443).

Correcting for short-range spatial non-linearities of CRT-based output devices (1993)

Most graphical output devices exhibit what has been termed spatial non-linearity: the effect of setting two adjacent pixels to a given value is not the same as the sum of the effects of setting those two pixels to the same value in isolation: checkerboards of different frequencies do not have the same apparent luminance. We present a method applicable to bit-mapped devices for compensating for short-range spatial non-linearity in error-diffused images. The modification to error diffusion is such that it can be used with any error diffusion technique. In essence, it consists of finding the influence of the neighbouring (output) pixels when making the decision of whether to turn on a given pixel, and passing errors computed accordingly.
On Topology Optimization and Routing in Integrated Access and Backhaul Networks: A Genetic Algorithm-Based Approach (2021)

In this paper, we study the problem of topology optimization and routing in integrated access and backhaul (IAB) networks, as one of the promising techniques for evolving 5G networks. We study the problem from different perspectives. We develop efficient genetic algorithm-based schemes for both IAB node placement and non-IAB backhaul link distribution, and evaluate the effect of routing on bypassing temporal blockages. Here, concentrating on millimeter wave-based communications, we study the service coverage probability, defined as the probability of the event that the user equipments' (UEs) minimum rate requirements are satisfied. Moreover, we study the effect of different parameters such as the antenna gain, blockage, and tree foliage on the system performance. Finally, we summarize the recent Rel-16 as well as the upcoming Rel-17 3GPP discussions on routing in IAB networks, and discuss the main challenges for enabling mesh-based IAB networks. As we show, with a proper network topology, IAB is an attractive approach to enable the network densification required by 5G and beyond.
All‐cause cancer mortality over 15 years in multi‐ethnic Mauritius: The impact of diabetes and intermediate forms of glucose tolerance (2012)

There are accumulating data describing the association between diabetes and cancer mortality from Westernised populations. There are no data describing the relationship between diabetes and cancer mortality in African or South Asian populations from developing countries. We explored the relationship of abnormal glucose tolerance and diabetes on cancer mortality risk in a large, multi-ethnic cohort from the developing nation of Mauritius. Population-based surveys were undertaken in 1987, 1992 and 1998. The 9559 participants comprised 66% of South Asian (Indian), 27% of African (Creole), and 7% of Chinese descent. Cox's proportional hazards model with time varying covariates was used to obtain hazard ratios (HRs) and 95% confidence intervals (95% CI) for risk of cancer mortality, after adjustment for confounding factors. In men, but not women, cancer mortality risk increased with rising 2h-PG levels with HR for the top versus bottom quintile of 2.77 (95%CI: 1.28 to 5.98). South Asian men with known diabetes had a significantly greater risk of cancer mortality than those with normal glucose tolerance (NGT) HR: 2.74 (95%CI: 1.00-7.56). Overall, impaired glucose tolerance was associated with an elevated risk of cancer mortality compared to NGT (HR: 1.47, 95% CI: 0.98-2.19), though this was not significant. We have shown that the association between abnormal glucose tolerance and cancer extends to those of African and South Asian descent. These results highlight the importance of understanding this relationship in a global context to direct future health policy given the rapid increase in type 2 diabetes, especially in developing nations.
Ion conducting polymers and polymer blends for alkali metal ion batteries (2013)

Electrolyte compositions for batteries such as lithium ion and lithium air batteries are described. In some embodiments the compositions are liquid compositions comprising (a) a homogeneous solvent system, said solvent system comprising a perfluropolyether (PFPE) and polyethylene oxide (PEO); and (b) an alkali metal salt dissolved in said solvent system. In other embodiments the compositions are solid electrolyte compositions comprising: (a) a solid polymer, said polymer comprising a crosslinked product of a crosslinkable perfluropolyether (PFPE) and a crosslinkable polyethylene oxide (PEO); and (b) an alkali metal ion salt dissolved in said polymer. Batteries containing such compositions as electrolytes are also described.
D ESEN (2019)

We address the problem of engineering a sociotechnical system (STS) with respect to its stakeholders’ requirements. We motivate a two-tier STS conception composed of a technical tier that provides control mechanisms and describes what actions are allowed by the software components, and a social tier that characterizes the stakeholders’ expectations of each other in terms of norms. We adopt agents as computational entities, each representing a different stakeholder. Unlike previous approaches, our framework, D ESEN , incorporates the social dimension into the formal verification process. Thus, D ESEN supports agents potentially violating applicable norms—a consequence of their autonomy. In addition to requirements verification, D ESEN supports refinement of STS specifications via design patterns to meet stated requirements. We evaluate D ESEN at three levels. We illustrate how D ESEN carries out refinement via the application of patterns on a hospital emergency scenario. We show via a human-subject study that a design process based on our patterns is helpful for participants who are inexperienced in conceptual modeling and norms. We provide an agent-based environment to simulate the hospital emergency scenario to compare STS specifications (including participant solutions from the human-subject study) with metrics indicating social welfare and norm compliance, and other domain dependent metrics.
LED-based Visible Light Communication in a Practical Indoor Interfered Environment Employing DMT and STBC (2014)

We demonstrate practical indoor VLC of 3.2-m transmission, and investigate multipath interference between LEDs. Employing repetition coding, 161~266-Mbps DMT-signals are achieved depending on interference severity. Employing STBC, about fixed 220-Mbps data rate could be achieved.
Immunopotentiating Effect of an Ayurvedic Preparation from Medicinal Plants (2009)

A formulation of Ocimum sanctum, Phyllanthus emblica, and Glycyrrhiza glabra in a defined ratio termed CIM-Candy was prepared based on Ayurvedic methodology. To study the humoral immune response, rabbit red blood corpuscles (rRBCs) were used as an antigen. Mice were immunized on day 7 and 14 days the start of the experiment using an intraperitoneal injection of 200 μl of rRBCs (2×108 cells/ml). Humoral immune response, body weight variation, and hematology parameters were studied. CIM-Candy at doses of 10 and 100 mg/kg body weight enhanced the immune function by significantly increasing (p<0.05) the hemagglutination antibody titer response against the rRBCs. Significant changes were not observed in body weight and hematology parameters when comparing the normal vehicle control and treatment groups. As the biological activity of the plant-derived formulation was not assigned to a single chemical, high performance thin layer chromatography (HPTLC) fingerprinting was also performed to confirm the chemical characteristic of the formulation. The results of this study suggest that the standardized formulation CIM-Candy exhibited significant humoral immune response in Swiss albino mice.
Ligand-lnduced Down-Regulation of Testicular and Ovarian Luteinizing Hormone (LH) Receptors Is Preceded by Tissue-Specific Inhibition of Alternatively Processed LH Receptor Transcripts (1991)

Down-regulation of plasma membrane receptors by homologous hormones has been found in diverse cell types. In testicular Leydig and ovarian luteal cells, treatment with LH/hCG decreases LH receptor content. Although suppression of LH-binding sites may result from ligand-induced receptor internalization, sequestration, and/or phosphorylation, the gonadotropins may also regulate receptor mRNA levels. We examined the regulation of testis LH receptor mRNAs in adult rats that received 10 or 200 IU hCG, using cRNA probes derived from the 5' extracellular domain (EC) or the 3' transmembrane domain (TM) of the rat receptor cDNA. Probe EC hybridized to predominant signals of 7 and 1.8 kilobases (kb) and weaker signals of 4.2 and 2.5 kb. However, probe TM hybridized to the three larger forms of the LH receptor mRNA, but not to the 1.8-kb species, suggesting that the latter form lacks the transmembrane domain. After 6 and 12 h of treatment with 200 or 10 IU hCG, respectively, hybridization to the larger mRNA species decreased by more than 60%, preceding decreases in testicular [125I]hCG binding. These transcripts were further inhibited (greater than 93%) between 24-72 h after hCG treatment and returned to 40% and 100% of control levels by days 6 and 9, respectively. In contrast, the truncated 1.8-kb LH receptor transcript was not affected by hCG treatment, indicating a differential suppressive effect of the ligand on its receptor mRNA levels. In the ovary, hybridization to probe EC revealed four transcripts with similar sizes as those found in the testes, with a predominant 7-kb species.(ABSTRACT TRUNCATED AT 250 WORDS)
SELF POTENTIAL MONITORING OF A BIOGEOBATTERY IN A HYDROCARBON CONTAMINATED SITE (2014)

The USGS Toxic Substances Hydrology Program crude-oil spill research site located near Bemidji, MN is the former site of a 1979 oil pipeline rupture. Approximately 11,000 barrels of oil were spilled over 6.5km of land. Early remediation efforts recovered approximately 7,800 barrels of the oil. The oil settled to the water table and biodegradation of the oil resulted in the formation of magnetite grains in the smear zone at the water table. The idea of the biogeobattery has been explored for this site since it presents a perfect situation for such a mechanism to be expressed. Intense microbial activity, as a result of the oil spill, right on the edge of the groundwater creates the needed oxic/anoxic boundary that forms the zone of the redox potential needed to power such a geobattery. The presence of electrically conductive magnetite, previously identified, on the smear zone provides the needed electronic conductor to complete the geo-battery closed circuit. We have performed a series of self potential (SP) measurements in boreholes in the contaminated, and control, areas to study the existence of such a mechanism. The in-situ measurements have yielded evidence indicating that a mechanism, as suggested from the biogeobattery model, is probably present at this site. Analysis of the field SP data compared to hydrological data collected on site indicates that the level of the water table may be the controlling factor that triggers this effect. Cores across this boundary have been collected for microbiological and geochemical analysis, as well as to attempt to recreate this phenomenon in the laboratory under controlled conditions. Laboratory experiments will simulate the field conditions, while controlling the level of the water table to explore the influence that the water table has on triggering the biogeobattery.
A direct stereoselective synthesis of 7β-hydroxytestosterone (1997)

Although 7 beta-hydroxytestosterone is a known product of hepatic androgen metabolism, there are no published methods for its chemical synthesis except from the equally difficult to obtain 7 beta-hydroxy-4-androstene-3,17-dione. We found that several seemingly straightforward routes for its synthesis failed. Consequently, we tried to produce 7 beta-hydroxytestosterone by enzymatic oxidation of 5-androstene-3 beta, 7 beta, 17 beta-triol with cholesterol oxidase (Brevibacterium sp.), a procedure previously used to synthesize 7 beta-hydroxy-4-cholesten-3-one from 3 beta, 7 beta-dihydroxycholesterol (Alexander and Fisher 1995). However, 5-androstene-3 beta, 7 beta, 17 beta-triol was, at best, a very poor substrate for the enzyme leading to the production of 7 beta-hydroxytestosterone in only trace amounts. Thus, we explored a strategy for the enzymatic synthesis in which a C8-ester at C-17 (5-androstene-3 beta, 7 beta, 17 beta-triol 17-caprylate) would serve to mimic the bulky and hydrophobic side chain of cholesterol and thus allow the C19-steroid to act as an effective substrate. When this ester was incubated with cholesterol oxidase, it was converted efficiently to 7 beta-hydroxytestosterone-17-caprylate. Attempts to remove the ester group by several mild hydrolytic procedures caused elimination of the 7 beta-hydroxyl group; we, therefore, obtained 7 beta-hydroxytestosterone by incubation of the intermediate ester with porcine lipase.
ARRAYS OF HIGH TEMPERATURE SUPERCONDUCTOR JOSE (1993)

We present results on parallel, series and two dimensional arrays of high temperature superconductor junctions. The parallel arrays show the expected field dep- endence of critical current, and can function as Vortex Flow Transistors. The series arrays give us data about the spread in junction critical currents for our present process. The two dimensional arrays show many of the phenomena previously observed in low To technology, such as field frustration of the phase transition, some evidence for superlattice states, and the tentative indications of giant Shapiro steps, showing large scale cooperative behaviour in the device. I. INTRODUCTION Grain boundary Josephson junctions have sufficient performance to allow the exploration of many of the types of device that have been studied with low temperature superconductors. We report the fabrication of multiplejunction devices of three types. Parallel arrays can form the basis of a form of Vortex Flow Transistor (VFT). Series arrays allow us to study the spread in critical currents of our junctions, and in principle they can be used as oscillators or mixers with greater dynamic range than a single junction. Finally we have made two dimensional arrays. The increase in internal coupling paths leads to much greater robustness of synchronisation of the junctions in the voltage state. The low T, realisations show great promise as agile and highly tuneable oscillators with much larger powers than single junctions. They have also been extensively studied as a prototype system for two-dimensional phase transitions. 11. SAMPLE PREPARATION
Directional antennas for electromagnetic mapping in a borehole (2023)

A bottom hole assembly used for a field operation is disclosed herein. The bottom hole assembly can include at least one directional antenna disposed on an outer surface of a first tubing pipe of a tubing string, where the at least one directional antenna receives a first electric current from at least one power source, where the first electric current generates a first magnetic field that radiates from the at least one directional antenna into a formation. The bottom hole assembly can also include at least one receiver disposed on a second tubing pipe of the tubing string, where the at least one receiver receives the first magnetic field returning from the formation.
Non-destructive enzymatic deamination enables single molecule long read sequencing for the determination of 5-methylcytosine and 5-hydroxymethylcytosine at single base resolution (2019)

Abstract The predominant methodology for DNA methylation analysis relies on the chemical deamination by sodium bisulfite of unmodified cytosine to uracil to permit the differential readout of methylated cytosines. Bisulfite treatment damages the DNA leading to fragmentation and loss of long-range methylation information. To overcome this limitation of bisulfite treated DNA we applied a new enzymatic deamination approach, termed EM-seq (Enzymatic Methyl-seq) to long-range sequencing technologies. Our methodology, named LR-EM-seq (Long Range Enzymatic Methyl-seq) preserves the integrity of DNA allowing long-range methylation profiling of 5-mC and 5-hmC over several kilobases of genomic DNA. When applied to known differentially methylated regions (DMR), LR-EM-seq achieves phasing of over 5 kb resulting in broader and better defined DMRs compared to previously reported. This result demonstrated the importance of phasing methylation for biologically relevant questions and the applicability of LR-EM-seq for long range epigenetic analysis at single molecule and single nucleotide resolution.
