Reducing false positives for object detection
… applicable Decoupled Classification Refinement (DCR) network. In particular, DCR places a separate classification network in parallel with the localization network (base detector). With ROI pooling placed on the early stage of the classification network, we enforce an adaptive receptive field in …

The effect of differential color refraction on astrometric observations of Solar System bodies and Earth satellites from ground-based optical telescopes
… bias from differential color refraction (DCR). This bias is evident in Minor Planet Center observations of asteroids with known spectral types and in observations of GPS and GLONASS satellites. DCR bias is on the order of 0.1 arcsec, and until recently, őxed-pattern star catalog errors …

Reading Between the Strands: Deciphering Double Stranded RNA-Based Immune Responses in Mosquito-Virus Interactions
… non-canonical functions of Dicer-2 (Dcr-2), a key RNAi component known to bind viral dsRNA. Using a CRISPR-generated Dcr-2 knockout cell line, coupled with poly(I:C)-based proteomics and transcriptomic profiling, we demonstrate that Dcr-2 regulates immune gene expression and restricts …

Detecting Dependence Change Points in Multivariate Time Series with Applications in Neuroscience and Finance
… called Dynamic Connectivity Regression (DCR), detects temporal change points in functional connectivity and estimates a graph, or set of relationships between ROIs, for data in the temporal partition that falls between pairs of change points. Hence, DCR allows for estimation of both the …

Effects of lateral heterogeneity on 1D D.C. resistivity and transient electromagnetic soundings in Kuwait
… (1D) resistivity using the D.C. resistivity (DCR) and transient electromagnetic (TEM) methods. For DCR, we implement a systematic approach to obtain a 1 D vertical profile using fixed-thickness and variable-thickness layer inversion techniques in succession. The optimal model has 6 layers …

Influence of surface hardening on single crystal nickel-based superalloys
… shot peening (MSP) and deep cold rolling (DCR), on the microstructures of single crystal nickel-based superalloys. These alloys have excellent high temperature properties, and consist of a randomly substituted face centred cubic matrix phase known as γ, together with a large volume fraction …

Power control for fair dynamic channel reservation
… control protocol, Dynamic Channel Reservation (DCR) in realistic high-density traffic scenarios. We focus on the communication requirements that allow vehicles to receive safety messages well enough in advance to warn the driver in a timely manner and avoid crashes. We observe performance …

Dynamic collision reduction protocol for ultra-wide bandwidth multiple access networks
… throughput of the dynamic collision reduction (DCR) protocol, a multiple access protocol that requires frame synchronization. At the physical-layer, we develop the optimal neighbor detector for ultra-wide bandwidth (UWB) signaling in a dense multipath environment with delay uncertainty. The …

Low Temperature Induced Signaling and Molecular Responses in Tomato
… and its full length cDNA sequence (named dcr) was cloned. Chilling treatment delays the endogenous rhythm of dcr transcripts and that may also associate with interfering specific protein phosphorylation states.

Single-photon avalanche photodiodes for quantum communication applications in the near-infrared
… operating mode, namely the dark count rate (DCR) of the detector, is defined for the first time. It is shown that while the measured dark current increases with the width of the attached guard ring (AGR), the DCR decreases with increasing AGR width, indicating that anode geometry is a more …

Investigating the role of germline RNA helicase-1 in Caenorhabditis elegans
… GLH-1, a constitutive P-granule component, and DCR-1, the riboendonuclease responsible for processing small RNAs in the miRNA pathway, have been shown to be interdependent in the C. elegans germline. The work described here is based on the hypothesis that if GLH-1 functions with DCR-1 in the …

You can't always get what you want : managing recreational use in the Middlesex Fells
… Department of Conservation and Recreation (DCR). I use the Middlesex Fells Trail System Plan as a case study to explore how public agencies resolve conflicts over open space. I find that the driving force behind DCR's recreational use decisions is user group input; the agency takes user …

CHARACTERIZATION AND DELINEATION OF POTENTIAL EVAPORITE GEOHAZARDS USING ELECTRICAL RESISTIVITY METHODS ALONG FM 2185, CULBERSON COUNTY, TEXAS
… (CCR) and Direct-Current Resistivity (DCR) methods were used to characterize evaporite karst features that do not manifest surficially but pose potential geohazard concerns. CCR data was acquired using the Geometrics OhmMapper G-858 resistivity system, which uses a dipole-dipole …

Time-restricted eating on inflammation and oxidative stress in overweight, older adults
… isocaloric IF versus daily caloric restriction (DCR) on weight loss and metabolic risk factors for chronic noncommunicable diseases in adults with overweight and obesity. This review synthesized findings from randomized controlled trials and found that the effects of IF regimens on plasma lipid, …

Power processing and active protection for photovoltaic energy extraction
… termed diffusion charge redistribution (DCR), is proposed to fully recover mismatch loss. The proposed technique processes power by leveraging the intrinsic solar cell capacitance rather than relying on externally added intermediate energy storage in order to drastically reduce to the …

Surrogate endpoints of survival in metastatic carcinoma
… time to progression (TTP), disease control rate (DCR), response rate (RR) and partial response (PR). Correlation was also demonstrated between OS and complete response (CR) in CRC and duration of response (DOR) in MBC. However, while strong relationships were found, the proportion of variance …

Role of the Sydney Medically Supervised Injecting Centre in reducing injecting drug use-related harm: evaluating accessibility, utilisation, coverage and selected health impacts
Drug Consumption Rooms (DCRs), where injecting drug users (IDUs) can use pre-obtained drugs in a hygienic and professionally supervised low threshold setting, aim to engage high risk IDUs, reduce public drug use, injecting-related morbidity and mortality, and improve access to drug treatment. This …

Cost Trends and Estimates for Dam Rehabilitation in the Commonwealth of Virginia
… organizations such as ASDSO and the Virginia DCR release cost estimates every few years to encourage more investment in dam infrastructure. Unfortunately, many cost estimates have been made with limited data and outdated methodologies. This research collects a new sample of cost data for …
