Abstract Background Foreign body aspiration (FBA) may be complicated by secondary respiratory tract infection. The spectrum of pathogens associated with FBA in China remains poorly described. This study aimed to obtain c...

Abstract A heated debate has been ongoing regarding the potential overlap in language disorders exhibited by children with developmental language disorder (DLD) and those with autism spectrum disorder plus language impai...

Abstract Background The genetic basis of autism spectrum disorder (ASD) is complicated by high heritability and substantial heterogeneity, in which de novo variants and polygenic burden from common variants have not been...

Axionlike particles (ALPs) are hypothetical light (sub-eV) bosons predicted in some extensions of the Standard Model of particle physics. In astrophysical environments comprising high-energy gamma rays and turbulent magn...

BackgroundAutism Spectrum Disorder (ASD) is primarily characterized by differences in communication and social interaction, but motor impairments are also commonly observed, often emerging in early childhood. Understandi...

ObjectiveTo analyze the rates of drug resistance of carbapenem-resistant Klebsiella pneumoniae (CRKP) and extended-spectrum β-lactamase-producing Escherichia coli (ESBL-E.coli) in bronchoalveolar lavage fluid (BALF) of ...

Abstract Direction of arrival algorithms are used, in general, to estimate a number of incident plane waves on the antenna array and their angles of incidence. In this paper, firstly, a new approach representing a more e...

For Banach spaces X and Y we study the vector-valued spectrum (Formula presented.), that is the set of non null algebra homomorphisms from (Formula presented.) to (Formula presented.), which is naturally projected onto t...

Abstract Cognitive radio networks (CRN) enable secondary users (SUs) to opportunistically access underutilized licensed spectrum while protecting primary users (PUs) from interference. However, robust spectrum sensing un...

Abstract Objective To analyze the scientific production regarding maternal folic acid (FA) supplementation and its relationship with autistic spectrum disorder (ASD). Data Sources We performed unrestricted electronic...

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by persistent deficits in social communication and interaction, alongside restricted, repetitive, and stereotyped patterns of behavior and int...

Abstract Background Actigraphy is widely used in research settings to objectively assess sleep–wake patterns; however, inconsistencies in device algorithms, hardware capabilities, and scoring procedures pose challenges...

BackgroundThe toxicities associated with immune checkpoint inhibitors (ICIs) can affect nearly all organ systems. Although previous studies have examined specific types of immune-related adverse events (irAEs) associated...

Two criteria for the spectra of relativistic waves are proposed. Zero-point radiation provides the identity representation of the conformal group in Minkowski spacetime. Thermal radiation provides the irreducible represe...

A near-unity unselective absorption spectrum is desirable for high-performance photovoltaics. Nanowire (NW) arrays are promising candidates for efficient solar cells due to nanophotonic absorption resonances in the solar...

Abstract Stroke remains a primary cause of disability globally. An in‐depth comprehension of gait impairments following a stroke is vital for crafting effective therapeutic interventions, and vertical ground reaction f...

Autism spectrum disorders (ASDs) are neuropsychiatric diseases characterized by impaired social interaction, communication deficits, and repetitive and stereotyped behaviors. ASD etiology is unknown, and both genetic and...

Abstract The software-defined radio has been allowing engineers the possibility of implementing operations on software that were previously only possible to be performed through hardware. With the continuous increase in ...

ABSTRACT Objective Placenta accreta spectrum (PAS) is a cause of massive obstetric hemorrhage and maternal mortality. The application of family-centered delivery techniques (FCDTs) during surgery to treat this disease i...

Abstract One of the critical limitations to use of bacteriocins produced by lactic acid bacteria as a substitute for chemical antibiotics is the narrow spectrum of their antibacterial activity. The aim of present study w...

Background: Thyroid cancer is one of the most prevalent endocrine neoplasms in Brazil, and radioiodine therapy (RAI) is a well-established adjuvant treatment. However, managing RAI can be particularly challenging in pati...
