I-A and I-E gene products of the murine histocompatibility complex (H-2) are expressed by most B cells and to varying degrees by macrophages and T cells (1, 2). I-J products are intimately involved in immune regulation and are expressed by Ts cells and their factors (TsF), 1 as well as by some Th cells and macrophages (3, 4). A great deal is known about the function, serology, and biochemistry ...

There have been significant advances in 3D object detection using LiDAR and camera fusion for autonomous driving. However, it is surprisingly difficult to effectively design location strategies point cloud-based networks. In this paper, we propose a novel two-stage sequential (TSF) method. the first stage of fusion, TSF generates enhanced cloud by combining raw semantic information image instan...

Florigens, the leaf-derived signals that initiate flowering, have been described as 'mysterious', 'elusive' and the 'Holy Grail' of plant biology. They are synthesized in response to appropriate photoperiods and move through the phloem tissue. It has been proposed that their composition is complex. The evidence that flowering locus T (FT) protein and its paralogue twin sister of FT (TSF) act as...

Eighteen single amino acid substitutions in phage P22 coat protein cause temperature-sensitive folding defects (tsf). Three intragenic global suppressor (su) substitutions (D163G, T166I and F170L), localized to a flexible loop, rescue the folding of several tsf coat proteins. Here we investigate the su substitutions in the absence of the original tsf substitutions. None of the su variant coat p...

Translaminar screw fixation (TSF) of the axis is considered as an efficient, safe and simple surgical procedure, however the study of the potential risk of TSF to the transverse foramen in lower cervical spine is lacked. Head-neck CT images of 60 patients were included in this study. Maximum screw length, laminar thickness, the screw angle and the laminar height were measured. The feasibility o...

The photosystem II core complex (TSF-IIa) is composed of polypeptides of molecular weight 54-, 47-, 42-, and 30 kilodaltons (kD) and cytochrome b-559. After treatment with trypsin or alpha-chymotrypsin for 20 hours, the TSF-IIa particles still retained their photochemical activity and the light-induced cytochrome b-559 signal, although all of the polypeptides of the complexes, except the 30 kD ...

To be relevant in terms of public health, widely-used toothpastes should have at least 1,000 ppm of soluble fluoride (F) concentration. Thus, the concentrations of total fluoride (TF) and total soluble fluoride (TSF) in the top-selling Brazilian toothpastes were evaluated. Samples (n=3) from toothpastes Colgate Anti-cáries(®), Colgate Total 12 Clean Mint(®), Colgate Tripla Ação Menta Original(®...

INTRODUCTION Malnutrition is common in maintenance hemodialysis (HD) and is associated with increased mortality and morbidity in affected patients. The aim of this study was to determine the prevalence of malnutrition and correlate the methods of nutritional assessment. METHODS We evaluated the nutritional status of 40 prevalent HD patients by subjective global assessment (SGA) score, anthrop...

Machine learning methods have been adopted in the literature as contenders to conventional solve energy time series forecasting (TSF) problems. Recently, deep emerged artificial intelligence field attaining astonishing performance a wide range of applications. Yet, evidence about their TSF problems, terms accuracy and computational requirements, is scanty. Most review articles that handle probl...

The Task Segment Framework (TSF) is a tool to analyze full typing flows of translation tasks as keylogged with timestamps recorded for keydown, keyup, mouse clicks and moves, actions performed in other applications. TSF assumes that intentional pauses flag stretches where subjects concentrate on unrecorded cognitive processes such planning assessment. interspersed are task segments, or without ...
