How Social Situations Affect the Relationships Between Academic Emotional Suppression and Expression and Likability Among Adolescents.

Social situation is an important factor in determining whether or not individuals express emotions and how effectively they express them, but few researchers have explored its role (e.g., with others of varying degrees of intimacy and hierarchy) in the social outcomes of academic emotional suppression and expression.

Low-cost 100 G PON based on a residual optical carrier for carrier recovery.

We experimentally demonstrate a cost-effective dual-polarization quadrature phase shift keying (DP-QPSK) coherent passive optical network (PON) system that operates at 100 Gbits/s/λ. This system utilizes distributed feedback lasers (DFBs) and a carrier recovery algorithm facilitated by a bifunctional frequency-domain pilot tone (FPT). To reduce costs in coherent PON implementations, low-cost DFBs are employed as the sole light sources, replacing the more expensive external cavity lasers (ECLs) at both the optical line terminal (OLT) and the optical network units (ONUs).

Search for meaning alleviated individual depressive symptoms during COVID-19 pandemic: The mediating role of optimism.

The COVID-19 pandemic and subsequent quarantine measures have disrupted people's normal pace of life and created excessive pressure. The current study examined the mitigating effect of search for meaning in life on individual depressive symptoms and the mediating role of optimism during COVID-19 lockdown period. A total of 462 participants (M = 37.

Carbonization test and orthogonal polynomial regression analysis of steel fiber reclaimed concrete.

To enhance the carbonation resistance of reclaimed concrete, several key factors affecting its performance were investigated. An orthogonal array (4³ × 2⁶) was employed to design the carbonation tests for steel fiber (SF) reinforced concrete. The study included varying SF volume ratios, along with considerations of different concrete ages (T) and water-cement ratios (W/R).

Application of modified Curie and SIOPEN skeleton scoring systems in F-AlF-NOTA-octreotide PET/CT for neuroblastoma.

Objective: The study aimed to explore the role of fluorine-18-aluminum fluoride-1,4,7-triazacyclononane-1,4,7-triacetic acid-octreotide (F-OC) positron emission tomography/computed tomography (PET/CT) in neuroblastoma (NB) and compared it with Iodine-123 labeled metaiodobenzylguanidine (I-MIBG) scintigraphy with single photon emission computed tomography/computed tomography (SPECT/CT), as well as to investigate the feasibility of the modified Curie scoring system and International Society of Pediatric Oncology Europe Neuroblastoma (SIOPEN) skeleton scoring system applied in F-OC PET/CT.

Methods: Patients with pathologically confirmed NB underwent I-MIBG scintigraphy with SPECT/CT and F-OC PET/CT according the standard imaging protocols. The interval between the two imaging techniques ranged from 0 to 22 days (median interval: 9 days).
