“The Volcano of Civilization Erupts at Night”: A Study of the Relationship Between Staying Up Late and Irrational Expression in the New Media Era
Authors: deng xinyi 
Published: March 2024

Abstract: The establishment of interactive communication patterns in new media give people a broad space for expression, yet the frequent outbreak of irrational speeches in the virtual society which happened at night also needs to be urgently given great attention by the research community. Based on the theoretical foundation of ELM peripheral route, inter group emotion-transmission and Croce's "intuitive knowledge",this paper uses a combination of questionnaires and semi-structured interviews to collect and analyze data. The phenomenon of staying up late generally puts individuals in an irrational state of mind, but it does not necessarily induce irrational behaviors in the process of online social behavior. The study explores the issue of the relationship between staying up late and irrational expressing on the Internet, and proposes new related hypotheses that could deepen future research on emotional communication with regard to the irrational expressions of Internet users at night.

Published: March 2024

BACKGROUND
Colorectal cancer (CRC) is a global health concern, with advanced-stage diagnoses contributing to poor prognoses. The efficacy of CRC screening has been well-established; nevertheless, a significant proportion of patients remain unscreened, with > 70% of cases diagnosed outside screening. Although identifying specific subgroups for whom CRC screening should be particularly recommended is crucial owing to limited resources, the association between the diagnostic routes and identification of these subgroups has been less appreciated. In the Japanese cancer registry, the diagnostic routes for groups discovered outside of screening are primarily categorized into those with comorbidities found during hospital visits and those with CRC-related symptoms.
AIM
To clarify the stage at CRC diagnosis based on diagnostic routes.
METHODS
We conducted a retrospective observational study using a cancer registry of patients with CRC between January 2016 and December 2019 at two hospitals. The diagnostic routes were primarily classified into three groups: Cancer screening, follow-up, and symptomatic. The early-stage was defined as Stages 0 or I. Multivariate and univariate logistic regressions were exploited to determine the odds of early-stage diagnosis in the symptomatic and cancer screening groups, referencing the follow-up group. The adjusted covariates were age, sex, and tumor location.
RESULTS
Of the 2083 patients, 715 (34.4%), 1064 (51.1%), and 304 (14.6%) belonged to the follow-up, symptomatic, and cancer screening groups, respectively. Among the 2083 patients, CRCs diagnosed at an early stage were 57.3% (410 of 715), 23.9% (254 of 1064), and 59.5% (181 of 304) in the follow-up, symptomatic, and cancer screening groups, respectively. The symptomatic group exhibited a lower likelihood of early-stage diagnosis than the follow-up group [P < 0.001, adjusted odds ratio (aOR), 0.23; 95% confidence interval (95%CI): 0.19-0.29]. The likelihood of diagnosis at an early stage was similar between the follow-up and cancer screening groups (P = 0.493, aOR for early-stage diagnosis in the cancer screening group vs follow-up group = 1.11; 95%CI = 0.82-1.49).
CONCLUSION
CRCs detected during hospital visits for comorbidities were diagnosed earlier, similar to cancer screening. CRC screening should be recommended, particularly for patients without periodical hospital visits for comorbidities.
A guide to measuring expert performance in forensic pattern matching
Authors: Robson Samuel G. , Searston Rachel A. , Thompson Matthew B. , Tangen Jason M. 
Published: March 2024

AbstractDecisions in forensic science are often binary. A firearms expert must decide whether a bullet was fired from a particular gun or not. A face comparison expert must decide whether a photograph matches a suspect or not. A fingerprint examiner must decide whether a crime scene fingerprint belongs to a suspect or not. Researchers who study these decisions have therefore quantified expert performance using measurement models derived largely from signal detection theory. Here we demonstrate that the design and measurement choices researchers make can have a dramatic effect on the conclusions drawn about the performance of forensic examiners. We introduce several performance models – proportion correct, diagnosticity ratio, and parametric and non-parametric signal detection measures – and apply them to forensic decisions. We use data from expert and novice fingerprint comparison decisions along with a resampling method to demonstrate how experimental results can change as a function of the task, case materials, and measurement model chosen. We also graphically show how response bias, prevalence, inconclusive responses, floor and ceiling effects, case sampling, and number of trials might affect one’s interpretation of expert performance in forensics. Finally, we discuss several considerations for experimental and diagnostic accuracy studies: (1) include an equal number of same-source and different-source trials; (2) record inconclusive responses separately from forced choices; (3) include a control comparison group; (4) counterbalance or randomly sample trials for each participant; and (5) present as many trials to participants as is practical.
Millimeter-wave CO and SiO Observations toward the Broad-velocity-width Molecular Feature CO 16.134–0.553: A Smith Cloud Scenario?

Abstract
We report the results of the CO J = 1–0 and SiO J = 2–1 mapping observations toward the broad-velocity-width molecular feature (BVF) CO 16.134–0.553 with the Nobeyama Radio Observatory 45 m telescope. The high-quality CO map shows that the 5 pc size BVF bridges two separate velocity components at V
LSR ≃ 40 km s−1 and 65 km s−1 in the position–velocity space. The kinetic power of CO 16.134–0.553 amounts to 7.8 × 102
L
⊙, whereas no apparent driving sources were identified. Prominent SiO emission was detected from the BVF and its root in the V
LSR ≃ 40 km s−1 component. In the CO Galactic plane survey data, CO 16.134–0.553 appears to correspond to the Galactic eastern rim of a 15 pc diameter expanding CO shell. A 1° diameter H i emission void and 4° long vertical H i filament were also found above and below the CO shell, respectively. We propose that the high-velocity plunge of a dark matter subhalo with a clump of baryonic matter was responsible for the formation of the H i void, CO 16.134–0.553/CO shell, and the H i filament.
Disk-induced Binary Precession: Implications for Dynamics and Multimessenger Observations of Black Hole Binaries
Authors: Tiede Christopher , D’Orazio Daniel J. , Zwick Lorenz , Duffell Paul C. 
Published: March 2024

Abstract
Many studies have recently documented the orbital response of eccentric binaries accreting from thin circumbinary disks, characterizing the change in the binary semimajor axis and eccentricity. We extend these calculations to include the precession of the binary’s longitude of periapse induced by the circumbinary disk, and we characterize this precession continuously with binary eccentricity e

b
for equal mass components. This disk-induced apsidal precession is prograde with a weak dependence on the binary eccentricity when e

b
≲ 0.4 and decreases approximately linearly for e

b
≳ 0.4; yet at all e

b
binary precession is faster than the rates of change to the semimajor axis and eccentricity by an order of magnitude. We estimate that such precession effects are likely most important for subparsec separated binaries with masses ≲107
M
⊙, like LISA precursors. We find that accreting, equal-mass LISA binaries with M < 106
M
⊙ (and the most massive M ∼ 107
M
⊙ binaries out to z ∼ 3) may acquire a detectable phase offset due to the disk-induced precession. Moreover, disk-induced precession can compete with general relativistic precession in a vacuum, making it important for observer-dependent electromagnetic searches for accreting massive binaries—like Doppler boost and binary self-lensing models—after potentially only a few orbital periods.
A Star-based Method for the Precise Flux Calibration of the Chinese Space Station Telescope Slitless Spectroscopic Survey

Published: March 2024

Abstract
The upcoming Chinese Space Station Telescope (CSST) slitless spectroscopic survey poses a challenge of flux calibration, which requires a large number of flux-standard stars. In this work, we design an uncertainty-aware residual attention network, the UaRA-net, to derive the CSST spectral energy distributions (SEDs) with a resolution of R = 200 over the wavelength range of 2500–10000 Å using LAMOST normalized spectra with a resolution of R = 2000 over the wavelength range of 4000–7000 Å. With the special structure and training strategy, the proposed model provides accurate predictions not only of SEDs, but also of their corresponding errors. The precision of the predicted SEDs depends on the effective temperature (T
eff), wavelength, and the LAMOST spectral signal-to-noise ratios (S/Ns), particularly in the GU band. For stars with T
eff = 6000 K, the typical SED precisions in the GU band are 4.2%, 2.1%, and 1.5% at S/N values of 20, 40, and 80, respectively. As T
eff increases to 8000 K, the precision increases to 1.2%, 0.6%, and 0.5%, respectively. The precision is higher at redder wavelengths. In the GI band, the typical SED precisions for stars with T
eff = 6000 K increase to 0.3%, 0.1%, and 0.1% at S/N values of 20, 40, and 80, respectively. We further verify our model using empirical MILES spectra and find a good performance. The proposed method will open up new possibilities for the optimal use of slitless spectra of the CSST and other surveys.

Authors: Niyaz Leyla , Kocak Nurullah , Subası Mustafa , Yucel Ozlem Eski 
Published: March 2024

Purpose:
To analyze the motor and sensory outcomes of strabismus surgery in children born preterm (premature group) and full-term (control group).

Methods:
The study was performed at a tertiary university hospital. Children who underwent strabismus surgery between 2012 and 2019 were retrospectively reviewed. The success of surgery, postoperative over-correction and undercorrection rates, and stereopsis and fusion test results were compared between the premature and control groups.

Results:

There were 70 patients in the premature group (mean gestational age: 31.25 weeks; range: 24 to 35 weeks) and 242 patients in the control group. The amounts of preoperative and postoperative deviations and overcorrection, undercorrection, and success rates were similar between the premature and control groups (
P
> .05). Stereopsis improved from 560 to 300 arc/sec postoperatively in the premature group (
P
= .066) and from 1,156 to 685 arc/sec in the control group (
P
< .001). The rate of fusion increased from 12.5% to 25% in the premature group (
P
= .50) and from 17% to 47% in the control group (
P
< .001). The analysis of strabismus subgroups revealed significant improvement of fusion in full-term patients (
P
< .001) and not in preterm patients (
P
= .50) with esotropia. Preoperative amount of deviation was the only risk factor for surgical success (
P
< .001). Age, sex, history of prematurity, and spherical equivalent refraction were not correlated with undercorrection (
P
> .05).

Conclusions:
Regardless of the type of strabismus, although the functional results after strabismus surgery were similar in preterm and full-term patients, the gain of stereopsis and central fusion was significantly higher in full-term patients compared to preterm patients.

Violent crowd flow detection from surveillance cameras using deep transfer learning–gated recurrent unit
Authors: Imah Elly Matul , Puspitasari Riskyana Dewi Intan 
Published: March 2024

AbstractViolence can be committed anywhere, even in crowded places. It is hence necessary to monitor human activities for public safety. Surveillance cameras can monitor surrounding activities but require human assistance to continuously monitor every incident. Automatic violence detection is needed for early warning and fast response. However, such automation is still challenging because of low video resolution and blind spots. This paper uses ResNet50v2 and the gated recurrent unit (GRU) algorithm to detect violence in the Movies, Hockey, and Crowd video datasets. Spatial features were extracted from each frame sequence of the video using a pretrained model from ResNet50V2, which was then classified using the optimal trained model on the GRU architecture. The experimental results were then compared with wavelet feature extraction methods and classification models, such as the convolutional neural network and long short‐term memory. The results show that the proposed combination of ResNet50V2 and GRU is robust and delivers the best performance in terms of accuracy, recall, precision, and F1‐score. The use of ResNet50V2 for feature extraction can improve model performance.
