This is a first part of an article which treats specialization in medicine using a system approach. Three main systemic factors (we called them discipline-making factors) are crucial for the emergence of a clinical specialty (in our case this specialty is neurosurgery): social-historical, scientific...

The transformation of the system for distributing quotas for the extraction of aquatic biological resources (ABR) in quotas in Russia affects the interests of many parties. The new system of allocation of rights to catch ABR, which provides for quotas for investment, changes the established order in...

In this paper, a kind of multi-functional polylactic acid-based membrane with adjustable aggregate thickness and properties was prepared. When the number of assembled layers was 20 bilayers, the mean thickness of every bilayer was found to be 10.75±0.25 nm, and the tensile strength was increased by...

ABSTRACT: Subclinical ketosis (SCK) is a prevalent metabolic disorder in dairy cows during the transition period, characterized by elevated BHB levels without overt clinical symptoms. This study employed a multicompartment lipidomic approach to investigate the systemic and localized lipid alteration...

We present a comprehensive study of formaldehyde (H _2 CO) absorption and radio recombination line (H _110 _α ) emission in 215 molecular clouds from the Bolocam Galactic Plane Survey, observed using the Nanshan 25 m radio telescope. H _2 CO was detected in 88 sources (40.93%) with 59 being new dete...

Abstract Tectonic carbon degassing is an important contributor to the global carbon cycle. South Eastern Europe is an active extensional tectonic region. This is the result of intense geodynamic events related to the closure of the Tethys Ocean, whose remnants include an ophiolite orogenic belt and...

A novel push-pull modulator based scheme to generate W-band millimeter-wave (mm-wave) vector signal was proposed and experimentally demonstrated. Related to an I&#x002F;Q modulator, push-pull modulator has the advantages of simple architecture, small insertion loss and low cost. Through combinin...

The improvement of flame-retardant properties of polyamide 6 (PA6) was achieved by using reduced graphene oxide decorated with halloysite nanotubes (HNTs-d-rGO) hybrid composite as the additive in PA6 matrix. The intimate integration of reduced graphene oxide (rGO) and halloysite nanotubes (HNTs) th...

Manipulation of group-velocity-locked vector solitons (GVLVSs) is numerically proposed and experimentally demonstrated. A pseudo-high-order GVLVS could be generated from a fundamental GVLVS with the help of a polarization-resolved system. Specifically, a pseudo-high-order GVLVS with a two-humped pul...

Objectives: Adipose tissue plays a critical role in obesity, as its dysfunction can impair lipid homeostasis and result in lipid overflow and ectopic lipid deposition in the liver. We previously demonstrated that Isthmin-1 (Ism1) regulates glucose uptake into the adipose tissue and suppresses hepati...
