The paper proposes a deep hybrid forest regression-based modeling method for measuring the compressive strength (CS) of concrete. Then, reduced feature vector is used as input to train multiple subforest models (SFM), predicted values are selected from subforests via KNN (K-nearest neighbor) combine them obtain layer regression (LRV), and it combined with improved LRV, then output this taken; s...

BACKGROUND The term nutcracker phenomenon (NCP) elucidates anatomical structure and hemodynamics, whereas nutcracker syndrome (NCS) refers to clinical manifestations. We present three cases of similar clinical features of hematuria and flank pain with different clinical outcomes. CASE REPORT Case 1: A 36-year-old Caucasian female with a past medical history (PMH) of HIV infection presented for ...

We consider the derivation of data-dependent simultaneous bandwidths for double kernel heteroscedasticity and autocorrelation consistent (DK-HAC) estimators. In addition to usual smoothing over lagged autocovariances classical HAC estimators, DK-HAC estimator also applies time direction. obtain optimal that jointly minimize global asymptotic MSE criterion discuss tradeoff between bias variance ...

Tuco-tucos (Ctenomys spp.) are subterranean rodents that produce territorial, high intensity long-range vocalizations (LRVs) of broadband and low frequency that are essential for long-distance communication between individuals in different tunnel systems. Despite their importance, the development of LRVs remains poorly understood. In adult Anillaco Tuco-Tucos (Ctenomys sp.) the LRV is composed ...

Two large reactors designed for solar water disinfection (SODIS) of harvested rainwater (HRW) were built and tested in Spain (controlled conditions) Uganda (field testing). Both use V-trough aluminium mirrors UV-transparent poly(methyl-methacrylate) (PMMA) photo-reactor tubes diameters, 100 mm 200 mm, treating 90L 140L per batch, respectively. No differences terms treatment performances obtaine...

Bioelectrochemical technologies offer alternative ways of treating wastewater and using this process to generate electricity. However, research in area is just beginning consider environmental transmission viruses present wastewater. The viral fecal indicator coliphage MS2 (the most frequently used pathogen model) was study, since it a well-known indigenous virus. scaled-up bioelectrochemical s...

Introduction. “The nutcracker syndrome” occurs due to abnormal compression of the left renal vein (LRV) between superior mesenteric artery and aorta. Clinical manifestations range from hematuria, proteinuria, pain in lumbar region, sided varicocele men, pudendal varicosity women development severe anemia failure some cases progressive phlebohypertension.Materials methods. The study included 210...

This paper proposes tests of linear hypotheses when the variables may be continuous-time processes with observations collected at a high sampling frequency over long span. Utilizing series run variance (LRV) estimation in place traditional kernel LRV estimation, we develop easy-to-implement and more accurate F both stationary nonstationary environments. The environment accommodates exogenous re...

In this work, a new indexing technique of data streams called BSTree is proposed. This technique uses the method of data discretization, SAX [4], to reduce online the dimensionality of data streams. It draws on Btree to build the index and finally uses an LRV (least Recently visited) pruning technique to rid the index structure from data whose last visit time exceeds a threshold value and thus ...
