In this paper, we utilize the advantages of an event camera to tackle visual place recognition (VPR) problem. The camera’s high measurement rate, low latency, and dynamic range make it well-suited overcome limitations conventional vision sensors. However, apply existing convolutional neural networks (CNNs) based algorithms such as NetVLAD, asynchronous stream should be converted a synchronous i...

Mesoscale convective systems (MCSs) contain both regions of convective and stratiform precipitation, and a bright band (BB) is often found in the stratiform region. Inflated reflectivity intensities in the BB often cause positive biases in radar quantitative precipitation estimation (QPE). A vertical profile of reflectivity (VPR) correction is necessary to reduce such biases. However, existing ...

The regulation of human immunodeficiency virus type 1 infection and replication in primary monocytes was investigated by mutagenesis of recombinant proviral clones containing an env determinant required for the infectivity of monocytes. Virus replication was assayed by determination of reverse transcriptase activity in culture fluids and by recovery of virus from monocytes following cocultivati...

We have purified a minor extracellular serine protease from a strain of Bacillus subtilis bearing null mutations in five extracellular protease genes: apr, npr, epr, bpr, and mpr (A. Sloma, C. Rudolph, G. Rufo, Jr., B. Sullivan, K. Theriault, D. Ally, and J. Pero, J. Bacteriol. 172:1024-1029, 1990). During purification, this novel protease (Vpr) was found bound in a complex in the void volume a...

This study presents a statistical analysis of the vertical structure of precipitationmeasured by NASA–Japan Aerospace ExplorationAgency’s (JAXA) Tropical RainfallMeasuringMission (TRMM) precipitation radar (PR) in the region of southern California, Arizona, and western NewMexico, where the ground-based NextGeneration Radar (NEXRAD) network finds difficulties in accurately measuring surface prec...

The efficiency of reverse transcription to synthesize viral DNA in infected cells greatly influences replication kinetics of retroviruses. However, viral replication in non-dividing cells such as resting T cells and terminally differentiated macrophages is potently and kinetically restricted by a host antiviral factor designated SAMHD1 (sterile alpha motif and HD-domain containing protein 1). S...

We have previously generated a macaque-tropic human immunodeficiency virus type 1 (HIV-1mt) clone designated MN4/LSDQgtu by genetic manipulation from a parental virus that replicates poorly in rhesus macaque cells. In rhesus cell line M1.3S and peripheral blood mononuclear cells (PBMCs), MN4/LSDQgtu grows comparably to a standard simian immunodeficiency virus clone derived from the rhesus macaq...

Visual place recognition (VPR) is considered among the most complicated tasks in SLAM due to multiple challenges of drastic variations both appearance and viewpoint. To address this issue, article presents a self-supervised lightweight VPR approach (namely CoCALC) that fully utilizes geometric information provided by images. The main thing makes CoCALC ultra-lightweight (only 0.27 MB) our use D...

In twelve anaesthetised, ventilated dogs the effects of hypercapnia and pharmacologically induced arterial hypotension and hypertension on the interrelation between volume-pressure response (VPR) and cerebro-spinal fluid (CSF) pulse pressure were studied during continuous inflation of a supratentorial extradural balloon. Hypercapnia did not significantly affect the intracranial volume-pressure ...

During Human Immunodeficiency Virus infection interactions take place between host and the pathogen. This interaction mainly determines the efficiency of viral infection and the disease progression. Human Immunodeficiency Virus infected cells responds to several antiviral immune mechanisms such as innate, cellular and humoral immune antiviral defense. This virus has also gained resistance to su...
