Objective To explore the role of teaching evaluation in the practice of “traditional Chinese medicine” course for eight-year undergraduates of Peking Union Medical College. Methods With a secret questionnaire survey, statistics and summariz...

The pure Yang-Mills field, I: fixed time existence

The convergence of renormalized perturbation theory to all finite orders is defined and shown to be valid for the fixed time perturbation theory of a pure Yang-Mills field. Two pure Yang-Mills quantum gauge field theories are constructed, o...

The countercyclical effect of fiscal rules in Russia

The instability of economic processes fuels the inconsistency of the revenue flow to the budget system. In order to overcome the cyclical nature of the budget process, which depends on cyclical fluctuations of economic conditions, fiscal ru...

NON-INVASIVE INVESTIGATIONS IN HEROIN USERS AND NON-USERS-A CASE CONTROL STUDY

bjective: To compare heroin users with their age and gender matched relatives as regards non-invasive investigations like chest x-ray, electrocardiography (ECG) and 2D-echocardiography. Study Design: Case control study. Place and Duration o...

Linear fractal evolution characteristics of rock crack distributions during loading process

Abstract To investigate the fractal characteristics of rock crack distributions during the loading process, discrete element method was used to make rock samples with joints and record the crack propagation. The Box-counting method was used...

A millifluidic study of cell-to-cell heterogeneity in growth-rate and cell-division capability in populations of isogenic cells of Chlamydomonas reinhardtii.

To address possible cell-to-cell heterogeneity in growth dynamics of isogenic cell populations of Chlamydomonas reinhardtii, we developed a millifluidic drop-based device that not only allows the analysis of populations grown from single ce...

The Balanced Opioid Initiative: protocol for a clustered, sequential, multiple-assignment randomized trial to construct an adaptive implementation strategy to improve guideline-concordant opioid prescribing in primary care

Abstract Background Rates of opioid prescribing tripled in the USA between 1999 and 2015 and were associated with significant increases in opioid misuse and overdose death. Roughly half of all opioids are prescribed in primary care. Althoug...

Utility of Bone Marrow Cell Block in the Diagnosis of Haematological Disorders: A Cross-sectional Study

Introduction: The examination of Bone Marrow Aspirate (BMA) smears and Biopsies (BMBx) are well established in the diagnosis of various haematological and non-haematological disorders. While both techniques have unique advantages over the o...

Data resource profile: a nationally representative linked pregnancy cohort in Canada integrating clinical, social, and environmental data

Introduction Perinatal outcomes are shaped by clinical, social, and environmental factors, yet Canada lacks a nationally representative pregnancy cohort capturing these influences at the individual-level. This gap has limited the ability to...

Development and validation of an online dynamic nomogram based on the atherogenic index of plasma to screen nonalcoholic fatty liver disease

Abstract Background Nonalcoholic fatty liver disease (NAFLD), a common liver disease worldwide, can be reversed early in life with lifestyle and medical interventions. This study aimed to develop a noninvasive tool to screen NAFLD accuratel...

The evacuation of industrial enterprises, educational institutions, and millions of Soviet citizens during the Great Patriotic War is a tragic page in the history of Russia. This complex operation involved the evacuation and placement of hu...

Linking Data for Mothers and Babies in De-Identified Electronic Health Data.

ObjectiveLinkage of longitudinal administrative data for mothers and babies supports research and service evaluation in several populations around the world. We established a linked mother-baby cohort using pseudonymised, population-level d...

A Model of Social Distancing for Interacting Age-Distributed Multi-Populations: An Analysis of Students’ In-Person Return to Schools

Because of the current scenario of the SARS-CoV-2 (COVID-19) pandemic in Brazil, whose vaccination campaign is in the initial stage, government authorities have pointed out towards the complete reopening of the economy. And recently for the...

OFDM AF Variable Gain Relay System for the Next Generation Mobile Cellular

In this paper we present analytical performance evaluation of a dual-hop OFDM amplify-andforward (AF) variable gain (VG) relay system implementing ordered subcarrier mapping (SCM) at the relay station (R), considered to be a very interestin...

Statistics

Statistics: A Very Short Introduction describes a field very different from the dry and dusty discipline of the popular imagination. In its place is an exciting subject which uses deep theory and powerful software tools to shed light and en...
