Object localization in images via fusion of SFM and YOLO

<title>Abstract</title> Along with the rapid development of computer vision, unmanned aerial vehicle (UAV) technology, and autonomous driving, the precise acquisition of coordinate information for captured objects in geospatial space has become a core requirement for numerous app...

The Astrocyte Clock Controls Circadian Perineuronal Net Remodeling, Synapse Strength and Learning Behavior

The circadian clock controls a vast array of cellular and organismal functions, from the molecular scale to behavior. While each cell is regimented by a cell-autonomous clock, few studies in the brain have dissected the circuit and behavioral contributions of cell-specific clocks...

Contrast-free super-resolution ultrasound imaging for microvascular assessment of murine subcutaneous tumour models in preclinical oncology

<title>Abstract</title> <bold>Introduction</bold> . Tumour vascularity is an important biomarker of tumour growth and therapeutic response. Current in vivo imaging methods have a limited ability to detect individual tumour vessels due to the small vessel size and low flow rates c...

Molecular characterization of mismatch repair deficient tumors in young Jordanian patients

<title>Abstract</title> In Jordan, approximately 19% of colorectal carcinomas (CRCs) in patients younger than 45 years show mismatch repair deficiency (MMRD) by immunohistochemistry (IHC). MMRD in pediatric high-grade gliomas (HGG) and CRC in Jordan appears substantially more fre...

Biocontrol of tomato soilborne diseases by fungivorous nematode Aphelenchoides bicaudatus

<title>Abstract</title> Crop soil-borne diseases caused by pathogens, such as Fusarium spp. and root-knot nematodes, contribute to substantial yield losses worldwide. This study investigated the biocontrol potential of the fungivorous nematode, Aphelenchoides bicaudatus isolate A...

High current speed events in a harbor channel driven by resonant sub-hourly sea level dynamics: an example from Varna, Black Sea

Abstract. Current and sea-level observations in the 2.4-km-long, 300-m-wide channel between Varna Lake and the Black Sea, conducted by three novel Hydromast stations with a 1-minute resolution, revealed that moderate sub-hourly dynamics were occasionally interrupted by high-ampli...

Aggregation behavior and intraspecific interactions among ring-necked snakes

Sociality, broadly defined as the property or tendency of a species to live in groups with conspecifics for at least part of their life cycle, has convergently evolved multiple times. While there has historically been a dearth of research on sociality in squamate reptiles, recent...

VIA1 is a conserved regulator of thylakoid membrane integrity that acts through VIPP1

Abstract Thylakoid membranes are indispensable for oxygenic photosynthesis, yet the mechanisms that protect these membranes from photooxidative damage remain poorly understood. By screening previously uncharacterized proteins induced during the chloroplast unfolded protein respon...

Photoacoustic Tomography with Time-Dependent Damping: Theoretical and a Convolutional Neural Network-Guided Numerical Inversion Procedure

Abstract. In photoacoustic tomography (PAT), a hybrid imaging modality that is based on the acoustic detection of optical absorption from biological tissue exposed to a pulsed laser, a short pulse laser generates an initial pressure proportional to the absorbed optical energy, wh...

Mapping teachers’ digital competence (TDC): a bibliometric analysis and systematic review

With the rapid digital transformation of education, teachers’ digital competence (TDC) has emerged as a key driver of educational modernisation. However, existing reviews remain fragmented and lack large-scale systematic syntheses. This study combined bibliometric analysis with a...

Heterogeneous Individual Valuations of a Mild Climate

Abstract This paper explores heterogeneous individual valuations of an important amenity, climate mildness, using a traditional Rosen-Roback empirical framework. It does so by including interaction terms between the amenity and worker characteristics in an hedonic wage regression...

Pamiparib plus surufatinib with ctDNA monitoring in platinum-resistant ovarian cancer after PARP inhibitor progression: a phase Ib/II trial (POST-PARPi)

<title>Abstract</title> Background PARP inhibitors (PARPi) are standard front-line maintenance therapy for advanced ovarian cancer, but the efficacy of PARPi retreatment in later lines remains unclear. This phase Ib/II study evaluated the combination of pamiparib (a PARPi) and su...

Rhomboid protease RHBDL2 is a calcium-activated suppressor of EGFR signalling in keratinocytes

Abstract Signalling via the epidermal growth factor receptor (EGFR) is indispensable for morphogenesis and tissue homeostasis. It is activated by extracellular ligands, typically released from transmembrane precursors by proteolysis. Ligand shedding activity is provided by the co...

Session State Continuity in Multi-Agent Voice Flows: A Systematic Review of Challenges, Patterns, and Research Gaps

Session State Continuity in Multi-Agent Voice Flows: A Systematic Review of Challenges, Patterns, and Research Gaps Multi-agent voice systems decompose telephony interactions into specialized sub-agents for authentication, billing, scheduling, and escalation. A pervasive failure...

Coupling electric and magnetic dipoles in Janus nanoplatelets via surface-selective hybridization

Coupling electric and magnetic dipoles within nanoscale building blocks offers a promising strategy for creating hybrid materials with coupled magnetic and electric functionality. Here, we demonstrate a proof-of-concept approach for realizing this concept in Janus nanoparticles t...

Labeling of PET and PP nanoplastic test materials with non-leachable π-conjugated fluorescent polymers

<title>Abstract</title> Micro- and nanoplastic (MNP) particles are widely present in nature, mainly due to the extensive overuse of single-use plastics combined with poor waste management. Despite the diversity in the environment, many experimental studies still rely almost exclu...

Association of articular eminence inclination and glenoid fossa roof thickness with sagittal skeletal classes: a CBCT study

<title>Abstract</title> Background This study aimed to evaluate the association between skeletal sagittal malocclusion (based on ANB angle) and temporomandibular joint (TMJ) morphology by assessing bilateral articular eminence inclination (aeı) and glenoid fossa roof thickness, a...

A MultitaskLarge Reasoning Model for Molecular Science
