The marine sulfate inventory represents the largest standing pool of electron acceptors, which, via microbial reduction, is responsible for roughly half organic matter mineralization globally in sediments. In addition to oxidation buried matter, reduction can be coupled methane migrating upward. Multiple sulfur isotope ratios were measured porewater sulfate, sulfide, elemental and pyrite from c...

The increasing availability and variety of global satellite products the rapid development new algorithms has provided great potential to generate a level data with different spatial, temporal, spectral resolutions. However, ability these synthetic spatiotemporal datasets accurately map monitor our planet on field or regional scale remains underexplored. This study aimed support future research...

An optical-electrical sub-sampling down-conversion receiver architecture leveraging low-jitter optical sampling is described. A simple interface between the optical and electrical domains is accomplished by combining a photodiode with a second-order continuous-time ∆Σ modulator. A prototype system implemented in 0.18 μm CMOS achieving 36.4 dB SNR in a 2 MHz BW with an OSR of 250 is demonstrated.

Jamming recognition is an essential step in radar detection and anti-jamming the complex electromagnetic environment. When radars detect unknown type of jamming that does not occur training set, existing algorithms fail to correctly recognize it. However, these can only this as one already exists our library. To address issue, we present two models for open set (OSR) accurately classify known d...

Abstract Rising sand temperatures resulting from climate warming may cause the ‘feminization’ of sea turtle populations, which have temperature-dependent sex determination. In July and October 2021, we conducted surveys using a drone (also referred to as an unmanned aerial vehicle or UAV) shore-based observations assess operational ratio (OSR) (number males females in breeding condition) for gr...

PURPOSE To retrospective assess the potential predictors for relapse and create an effective clinical mode for surveillance after orchidectomy in clinical stage I non-seminomatous germ cell testicular tumors (CSI-NSGCTs). MATERIALS AND METHODS We analyzed data for CSI-NSGCTs patients with non-lymphatic vascular invasion, %ECa < 50% (percentage of embryonal carcinoma < 50%), and negative or de...

Safety risk management has a considerable effect on disproportionate injury rate of construction industry, project cost and both labor and public morale. On the other hand time-cost optimization (TCO) may earn a big profit for project stakeholders. This paper has addressed these issues to present a multi-objective optimization model to simultaneously optimize total time, total cost and overall ...

This paper brief the use of very high precision Noise shaping sigma delta modulation techniques for high applications that require a signal-to-noise ratio and high resolution. A continuous-time delta-sigma A/D modulator with OSR of 40, signal bandwidth of 1.5625 MHz and clocked at 500MHz is implemented. This achieves 78 dB SNR and 12 bits of resolution.

Identifying and tracking the influence of industrial activities on streams lakes is a priority for monitoring in Canada’s oil sands region (OSR). While differences indicators are often found waterbodies adjacent to mining facilities, confounding natural exposures bitumen other stressors can affect identification effects. However, recent work suggests metrics activity at individual including pro...

ObjectiveAge is an independent risk factor for mortality after both elective open surgical repair (OSR) and endovascular aneurysm (EVAR). As a result of ageing population, the less invasive nature EVAR, number patients over 80 years (octogenarians) being treated increasing. The morbidity following surgery are increased octogenarians. However, octogenarians who have either low or high peri-opera...
