Why Your Back Hurts, and What You Can Do About It

Lifehacker.com 

Saying “my back hurts” is a bit like saying “my car is making a noise.” It may be serious, or it may be nothing, and only a professional will know for sure. But if you have back pain, especially in your lower back, you’re not alone: By some estimates, 75% of us will have an achy lower back at some point in our lives,…

Collation of a century of soil invertebrate abundance data suggests long-term declines in earthworms but not tipulids

Plos.org 

by Ailidh E. Barnes, Robert A. Robinson, James W. Pearce-Higgins

Large-scale declines in terrestrial insects have been reported over much of Europe and across the world, however, population change assessments of other key invertebrate groups, such as soil invertebrates, have been largely neglected through a lack of available monitoring data. This study collates historic data from previously published studies to assess whether it is possible to infer previously undocumented long-term changes in soil invertebrate abundance.

Biogenic sunflower oil-chitosan decorated fly ash nanocomposite film using white shrimp shell waste: Antibacterial and immunomodulatory potential

Plos.org 

by Seham S. Alterary, Musarat Amina, Maha F. El-Tohamy

A new sunflower oil-chitosan decorated fly ash (sunflower oil/FA-CSNPs) bionanocomposite film was synthesized using the extract of Litopenaeus vannamei (White shrimp) and evaluated as an antibacterial and immunomodulatory agent. Fly ash-chitosan nanoparticles were produced by using chitosan (CS) isolated from white shrimp extract, glacial acetic acid and sodium tripolyphosphate solution as cross-linkage. The ultrafine polymeric sunflower... Читать дальше...

Prediction and visualization of Mergers and Acquisitions using Economic Complexity

Plos.org 

by Lorenzo Arsini, Matteo Straccamore, Andrea Zaccaria

Mergers and Acquisitions represent important forms of business deals, both because of the volumes involved in the transactions and because of the role of the innovation activity of companies. Nevertheless, Economic Complexity methods have not been applied to the study of this field. By considering the patent activity of about one thousand companies, we develop a method to predict future acquisitions by assuming that companies deal more frequently with technologically related ones.

Interpretation of southern hemisphere humpback whale diet via stable isotopes; implications of tissue-specific analysis

Plos.org 

by June Eggebo, Jasmin Groß, Susan Bengtson Nash

Blubber and skin are commonly used tissues in stable isotope analysis for the purpose of investigating cetacean diet. Critical comparison of tissue-specific isotopic signals is, however, lacking resulting in uncertainty surrounding the representativeness and therefore utility of different tissues for accurate determination of recent foraging. This study used remotely biopsied blubber and skin tissues from southern hemisphere humpback whales... Читать дальше...

A real-time voice cloning system with multiple algorithms for speech quality improvement

Plos.org 

by Weixin Hu, Xianyou Zhu

With the development of computer technology, speech synthesis techniques are becoming increasingly sophisticated. Speech cloning can be performed as a subtask of speech synthesis technology by using deep learning techniques to extract acoustic information from human voices and combine it with text to output a natural human voice. However, traditional speech cloning technology still has certain limitations; excessively large text inputs cannot be adequately processed... Читать дальше...

Regional intergenerational mobility and corporate innovation: Evidence from China

Plos.org 

by Changfu Luo, Lian Xie

By stimulating social vitality and improving innovation efficiency, intergenerational mobility plays an essential role in economic development. With the data from China Labor-force Dynamic Survey (CLDS) and A-share listed companies, this paper uses the methodology of intergenerational order correlation to measure regional intergenerational mobility, and examines the impact of regional intergenerational mobility on corporate innovation. The results are as follows:... Читать дальше...

How do caves breathe: The airflow patterns in karst underground

Plos.org 

by Franci Gabrovšek

Caves and their surrounding fracture systems in the vadose zone of karst regions host a unique atmospheric environment. Understanding the airflow patterns in caves is critical to understanding the properties of the subsurface atmosphere and the chemical interactions between air, water, and rock. The most common driver of airflow in caves is the density difference between the subsurface and the outside air, known as the chimney effect. Observations show that seasonal airflow...

A general algorithm for error-in-variables regression modelling using Monte Carlo expectation maximization

Plos.org 

by Jakub Stoklosa, Wen-Han Hwang, David I. Warton

In regression modelling, measurement error models are often needed to correct for uncertainty arising from measurements of covariates/predictor variables. The literature on measurement error (or errors-in-variables) modelling is plentiful, however, general algorithms and software for maximum likelihood estimation of models with measurement error are not as readily available, in a form that they can be used by applied researchers without relatively advanced statistical expertise.

The effect of C/N ratio and its frequent addition on commensal and pathogenic bacterial abundances in shrimp Litopeaneus vanname gut in a biofloc system: Ratio and frequent addition interaction matters

Plos.org 

by Abdallah Ghonimy, Zhao Chen, Jian Li

The environmental biotic and abiotic factors form a complicated relationship with the host intestinal microbiota. In our study, we applied different levels of C/N ratio (10, 15, 20) and frequent addition times (once, twice, triple a day) in a factorial experimental design. GC/LC analysis of filtrated biofloc (BF) samples revealed the highest relative fold change for the untargeted bioactive molecules among different treatments, whereas the 16s rRNA...
