Lighting education is a foundational component of cinematography education. However, there still lack knowledge on the design VR system for teaching cinematography. In this work, we present our soundstage instructors and learners to emulate lighting in virtual scenarios then evaluate it from five aspects user study. Qualitative quantitative feedback study shows promising results. We further discuss benefits approach opportunities future research.

Distributed transaction systems incur extensive cross-node communication to execute and commit serializable OLTP transactions. As a result, their performance greatly suffers. Caching data at nodes that transactions can cut down remote reads. Batching for validation persistence amortize the cost during committing. However, caching batching significantly increase likelihood of conflicts, causing expensive aborts. In this paper, we develop Hackwrench address challenge batching. Instead aborting...

Today, most database-backed web applications depend on the database to handle deadlocks. At runtime, monitors progress of transaction execution detect deadlocks and abort affected transactions. However, this common detect-and-recover strategy is costly performance as aborted transactions waste CPU resources.To avoid deadlock-induced degradation, developers aim reorganize application code remove Unfortunately, doing so difficult for applications. Not only do their implementations include...

This study aims to investigate novel clinical risk factors for cognitive impairment (CI) in elderly.A total of 3221 patients (259 with CI and 2,962 subjects without CI) were recruited into this nested case-control who underwent cerebral magnetic resonance angiography (MRA) from 2007 2021. All the data MRA imaging recorded followed by standardization processing blindly. The maximum stenosis score posterior circulatory artery, including basilar bilateral artery (PCA), was calculated automatic...

Research on the cooperative adaptive cruise control (CACC) algorithm is primarily concerned with longitudinal of straight scenes. In contrast, lateral involved in certain traffic scenes such as lane changing or turning has rarely been studied. this paper, we propose an that based Frenet frame. The decouples vehicle motion from complex two dimensions to simple one dimension, which can simplify controller design and improve solution efficiency. First, dynamics model established Through a...

Abstract Background: Salinity is among the most harmful agents that impacts alfalfa’s productivity. However, little known regarding how salinity tolerance trait regulated by lncRNAs in alfalfa. To evaluate mRNAs and associated with to stress alfalfa, root transcriptomics of two alfalfa cultivars differing tolerance, i.e., GN5 (tolerant salinity) GN3 (sensitive salinity), were investigated under 0 150 mM NaCl treatments. Results: A total 172,986 117,677 identified, which 2288 1466...

In the PhysioNet/Computing in Cardiology Challenge 2021, our team, DrCubic, develops a novel approach to classify cardiac abnormalities using reduced-lead ECG recordings. approach, we incorporate peak detection as self-supervised auxiliary task. We build model based on SE-ResNet, and integrate models of different input lengths sampling rates. Inspired by last year's challenge results, investigate various settings techniques, select best ones, considering intra-source performance inter-source...

Citrus reticulata Blanco has been widely used to cure some diseases such as cold, cough and indigestion. This study is aimed at determining the antidepressant-like effect of C. essential oils (CREOs) in reserpine-induced depression mice, well its possible mechanisms. The compositions CREOs are firstly analyzed by gas chromatography-mass spectrometry (GC-MS), which d-limonene main component. Moreover, results from forced swimming tail suspension tests show that inhalation can significantly...

Abstract In this paper, we propose an arc-remodified long period fiber grating (AR-LPFG) and introduce the ratios of shift-distance two resonant dips (RSRDs) as a novel distinguishing index to monitor bending absolute condition which refers detect curvature directions under stationary status. The AR-LPFG is configured by arc-remodifying LPFG that prepared from CO 2 laser. refractive modulated again arc-remodification method results in new dips. Two orthogonal are distinguished comparing...

We revisit the standard bisimulation equalities in process models free of restriction operator. As is well-known, general weak bisimilarity coarser than strong because it abstracts from internal actions. In absence restriction, those actions become somewhat visible, so one might wonder if still 'weak'. show that both CCScore (i.e., Milner's CCS without $\tau$-prefix, summation and relabelling) its higher-order variant (named HOCCScore), indeed remains weak, i.e., strictly bisimilarity, even...

Meta search engine is an effective tool for searching information online. In comparison with independent like Google, Bing, and etc., meta has a wider coverage can meet the requirement of retrieval in better manner. particular, when query received from user, sends it to some proper candidate member engines, collects results them, then replies user. An important issue here how select underlying engines. this paper, we focus on selection engine. We propose design based combination weighted...

Abstract Full configuration interaction calculations are performed for He 2 using various orbital basis sets of the aug‐cc‐pVXZ type, with correlation energies being extrapolated to complete set (CBS) limit. A two‐point CBS extrapolation formula has been utilized such a purpose. It is shown that offset parameter k ( R ) optimized equilibrium distance not uniformly applicable HeHe distances in very short region potential energy curve. The repulsive curve can be largely different one...
