Epidermal Differentiation Genes of the Common Wall Lizard Encode Proteins with Extremely Biased Amino Acid Contents

The epidermal differentiation complex (EDC) is a cluster of genes that code for protein components of cornified cells on the skin surface of amniotes. Squamates are the most species-rich clade of reptiles with skin adaptations to many different environments. As the genetic regulation of the skin epidermis and its evolution has been characterized for only a few species so far, we aimed to determine...

Unfolding entrepreneurial resourcefulness: a systematic literature review

Purpose Literature on entrepreneurial resourcefulness (ER) has grown constantly in the last two decades. ER is a construct that describes the specific behavior of entrepreneurs, focusing on the generation and deployment of resources to pursue an opportunity. Since the ER literature has expanded and diversified, the purpose of this study is to integrate its findings with existing knowledge about ...

Gender differences and new venture performance

Purpose This study compares the performance of female majority-owned new ventures (FNV) vs. male majority-owned new ventures (MNV). It analyzes the differences in levels of variables such as education, the same industry work experience of owners, and other venture level attributes between FNVs and MNVs. More importantly, this study employs decomposition techniques to determine the individual cont...

Use of CAMS near Real-Time Aerosols in the HARMONIE-AROME NWP Model

Near real-time aerosol fields from the Copernicus Atmospheric Monitoring Services (CAMS), operated by the European Centre for Medium-Range Weather Forecasts (ECMWF), are configured for use in the HARMONIE-AROME Numerical Weather Prediction model. Aerosol mass mixing ratios from CAMS are introduced in the model through the first guess and lateral boundary conditions and are advected by the model dy...

Signs of frost drought in stem diameter variations

Frost drought refers to the chronic or acute desiccation of trees exposed to high evaporative pressures while being rooted in cold or frozen soils. This phenomenon has been known for more than a century but is still poorly characterized. Summer desiccation manifests itself as long-term stem contractions. Similar contractions have been reported in winter. In this study, we investigated the causes o...

Extreme Convective Gusts in the Contiguous USA

Most damage to buildings across the contiguous United States of America (USA) is caused by gusts in convective events associated with thunderstorms. Design rules for structures to resist these events rely on the integrity of meteorological observations and the methods of assessment. These issues were addressed for the US Automated Surface Observation System (ASOS) in six preliminary studies publis...

Mechanical characteristics of dissimilar friction stir welding processes of aluminium alloy [AA 2024-T351 and AA 7075-T651]

Aerospace industries have remained dependent on aluminium alloys for airframe structural components manufacturing due to their superior strength, fracture toughness, and ability to resist corrosion. Especially, AA2024 and AA7075 have been the most prominent and timely tested robust aluminium alloys in these manufacturing sectors. However, joining these aluminium alloys through conventional fusion ...

Multi-Response Optimization of Process Parameters in Friction Stir Welding of AA 8011-H14 / AA 5052-H34 using Taguchi Grey Relational Analysis

Friction stir welding (FSW) offers a distinct advantage in its ability to effectively join dissimilar metals and alloys. This study focuses on the butt welding of AA 8011-H14 and AA5052-H34 through FSW, aiming to explore the influence of process parameters on crucial mechanical properties such as ultimate tensile strength, yield strength, percentage elongation, and hardness. The examination of the...

Unexpected abnormal coagulation test results in a 2-year-old child

Rejection of the sample with repeated blood withdrawal is always an unwanted consequence of sample nonconformity and preanalytical errors, especially in the most vulnerable population – children. Here is presented a case with unexpected abnormal coagulation test results in a 2-yearold child with no previously documented coagulation disorder. Child is planned for tympanostomy tubes removal unde...

How Should Surveillance Systems Account for Concurrent Intravascular Catheters?

The risk of central venous catheter (CVC)-associated bloodstream infections has decreased dramatically.1 The same may not be true for infections associated with short-term peripheral venous catheters.2 The effects of future preventive efforts should be measured using data derived from evidence-based surveillance programs. Dube et al3 describe a multicenter, retrospective cohort study that assessed...
