In this article, a broadband Home Accessories 3-dB directional coupler is proposed using groove gap waveguide (GGW) structures.Gap waveguide technology has been introduced to overcome manufacturing and assembling challenges of different millimeter-wave components and devices.The presented coupler has wideband coupling flatness with low return loss

Intrastratal karst is by far the predominant gypsum karst type.Its development may begin in deep-seated settings within rocks already buried by younger strata, and it proceeds increasingly rapidly as uplift brings gypsum sequences into progressively shallower positions.Such development commonly occurs under confined (artesian) hydrogeological condi

Anxiety disorders are among the most prevalent mental disorders.Present Ship Model treatments such as cognitive behavior therapy and pharmacological treatments show only moderate success, which emphasizes the importance for the development of new treatment protocols.Non-invasive brain stimulation methods such as repetitive transcranial magnetic sti

The article presents a systemic and historical view of wars taking into account the generalization of modern concepts about their nature and causes.The generalization is produced on the basis of a political and sociological apparatus with such basic concepts as: "concerns" of different types (including "interests", "motives", "goals", "values"), an

IntroductionSkeletal muscle satellite cells (MuSCs or stem cells) play a crucial role in muscle development, maintenance, and regeneration, supporting both hypertrophy and regenerative myogenesis.Syndecans (SDCs) act as communication bridges within the muscle microenvironment, regulating interactions with extracellular matrix components and contrib
