Single-photon avalanche diodes (SPADs) are widely used for weak light detection due to their high gain and sensitivity. Unfortunately, SPAD devices have random telegraph signal (RTS) noise during the transition phase, which makes circuit design more difficult. Therefore, modeling of RTS in is great significance processing circuits. However, not included traditional equivalent model. In response...

A new imager for 3D near-infrared imaging has been designed based on a single-photon avalanche diode (SPAD) imager with 128x128 pixels capable of performing time-resolved measurements with a resolution of 97ps. The imager linearity has been improved to make more accurate measurements. A new optical setup has been implemented in order to prove the suitability of this kind of sensors for this app...

One method for refining nitrogen (N) application in corn is use of in-season crop sensing. To aid producers in making decisions regarding N rate adjustments, a calibrated relationship between sensor-derived information and expected N application need should be established. Nitrogen rate trials were conducted at multiple sites across Iowa in 2001-2003. Nitrogen was applied at or shortly after co...

This paper presents a study of the predictive value of family relationships from genealogies, and its impact on the delayed ageing. The study comprised adult population over 18 years of age of two urban family practices (N = 1700). The study sample included all patients (total = 581; 57.3% female, 42.7% male) having sought medical assistance of any kind in the period of three consecutive months...

This work presents a dual-junction, single-photon avalanche diode (SPAD) with electrical μ-lens designed and simulated in 90 nm standard complementary metal oxide semiconductor (CMOS) technology. The evaluated structure can collect the photons impinging beneath the pixel guard ring, as well as the pixel active area. The fill factor of the SPAD increases from 12.5% to 42% in comparison with simi...

Humic acid fertilizer (HA) incorporation is a common method for improving crop growth and soil fertility. However, the effects of HA on rice are still unknown. We conducted two-year field experiment to determine radiation use, growth, yield grown with five different rates: 110 kg?ha?1 100% urea (pure nitrogen) (T1); 30% 70% (T2); 50% (T3); (T4), 1500 (T5). The results showed that T2 treatment h...

The direct response of Silicon PhotoMultipliers being traversed by a MIP charged particle have been studied in systematic way for the first time. Using beam test data, time resolution and crosstalk probability measured. A characterization SiPM means laser is also reported. results obtained different sensors indicate measured around 40-70 ps. Although particles are expected to traverse only one ...

Sickle-cell intrahepatic cholestasis (SCIC) is an uncommon complication of sickle-cell disease (SCD), which can be life-threating if left untreated. We present the case of a 28-year-old man with SCD, who presented with jaundice and abdominal pain, one month after hydroxyurea discontinuation. Laboratory investigation revealed solely increased serum bilirubin, mainly conjugated, and imaging studi...

Whole-cell biosensors are potential candidates for on-line and in situ environmental monitoring. In this work we present a new design of a whole-cell bioluminescence biosensor for water toxicity detection, based on genetically engineered Escherichia coli bacteria, carrying a recA::luxCDABE promoter-reporter fusion. Sensitive optical detection is achieved using a single photon avalanche photodio...
