Abstract:
Identifying undocumented or potential future interactions among species is a challenge facing modern ecologists. Recent link prediction methods rely on trait data; however, large species interaction databases are typically sparse and covariates are limited to only a fraction of species. On the other hand, evolutionary relationships, encoded as phylogenetic trees, can act as proxies for underlying traits and historical patterns of parasite sharing among hosts. We show that, using a network-based conditional model, phylogenetic information provides strong predictive power in a recently published global database of host-parasite interactions. By scaling the phylogeny using an evolutionary model, our method allows for biological interpretation often missing from latent variable models. To further improve on the phylogeny-only model, we combine a hierarchical Bayesian latent score framework for bipartite graphs that accounts for the number of interactions per species with host dependence informed by phylogeny. Combining the two information sources yields significant improvement in predictive accuracy over each of the submodels alone. As many interaction networks are constructed from presence-only data, we extend the model by integrating a correction mechanism for missing interactions which proves valuable in reducing uncertainty in unobserved interactions.

As the clock ticks on the Millennium Development Goals (MDGs), the world community is deep in discussion over the successor global framework. Many current practices are damaging the planet’s ecosystems and the biodiversity essential for healthy food production. By 2050 an estimated additional 2 billion people will be living on Earth.  This means food production must rise by 60%. From 8 MDGs [...]

Perhaps from outer space, it is easy to get the perspective that we only have one earth and that it is succumbing to climate change. Seeing the earth from space though is a feat that, unfortunately, most of us will never accomplish. We have to rely on Astronaut Thomas Pesquet and the other brave women and men astronauts to provide [...]

Differential detergent fractionation of cells is a rapid method for extraction of cytoplasmic and nuclear proteins in preparation of an immunoprecipitation. This method can be applied for use of adherent or suspension cells and can significantly reduce nonspecific background in an immunoprecipitation by separation of cellular compartments into individual fractions. The lysis of cells by differential detergents permits the rapid extraction of proteins from the cytoplasm (digitonin), the cytoplasmic membranes, and organelles (Triton X-100), and nucleoplasm (Tween/DOC), facilitated through the use of distinct extraction buffers. Cytoplasmic and nuclear matrix proteins as well as DNA are left behind during the detergent-based extraction.

A pair of new studies find that, when given a choice, white parents tend to send their children to schools that are predominantly white.

Infants and children with diagnosed food allergy are at risk for acute, potentially life-threatening symptoms. Limited data are available on the frequency, severity, and circumstances of reactions and caretaker medical response.

This study describes food allergy reaction frequency, circumstances, and response. Pitfalls that may inform improved anticipatory guidance included lack of vigilance, misreading ingredient labels, allergen cross-contact, nonaccidental allergen feeding, and underutilization of epinephrine for severe reactions.

Antimicrobials are a medication class frequently implicated in pediatric adverse drug reactions (ADRs). Trimethoprim-sulfamethoxazole (TMP-SMX) is long recognized as a contributor to the burden of these undesired and unpredictable events.

TMP-SMX ADRs increased from 2000 to 2009, with the majority of children taking the antibiotic for skin and soft tissue infections. The significant increase in TMP-SMX prescribing for these infections may result in a continued increase of associated ADRs. (Read the full article)

Previous evaluations of local reactions after the fifth diphtheria-tetanus-acellular pertussis (DTaP) vaccine in children 4 to 6 years of age have revealed that vaccination in the thigh is associated with a lower risk of local reactions compared with vaccination in the arm.

Among children 12 to 35 months of age, injection of DTaP vaccine in the thigh is associated with a lower risk of local reactions compared with vaccination in the arm. (Read the full article)

Hospitalized pediatric patients are often exposed to many medications during an inpatient admission. Drug–drug interactions may increase the risk of developing medication-related adverse drug events, leading to serious clinical morbidity and mortality.

Exposure to "major" potential drug–drug interactions occurs in 41% of pediatric hospitalizations in children’s hospitals. One-half of all these exposures were due to less common specific drug pairs (≤3% of patients exposed per hospital day) and thus may be less clinically familiar. (Read the full article)

As the world continues to face the ongoing impacts of the global coronavirus pandemic, Penn State President Eric Barron outlined Friday the University’s actions over the past five months to address the challenges, protect the health and safety of the University community, and prepare for the future.

Penn State Executive Vice President and Provost Nicholas P. Jones has shared a message updating the University community on steps being taken to monitor the evolving worldwide coronavirus outbreak and prepare for the safety and well-being of students, faculty, staff and visitors.

Today, 98% of households with 2- to 8-year-old children include a mobile device, like smartphones, tablets, and iPods or other smart-mobile devices, an increase from 75% in 2013. We are really connected, but not connecting at all.

According to the Pradhan Mantri Jan Dhan Yojana (PMJDY) website, the total number of RuPay cards issued so far stands at over 290 million.

Digital transactions have gained new heights in the month of March as India announced a lockdown due to coronavirus. The total value of Real Time Gross Settlement (RTGS) transactions also witnessed a spike.

The development also shows the government's push for digital technology has enabled people to access banking services even when the pandemic spread its tentacles.

 Hi,

I'm using OVM transaction level tracing in SV. I was wondering if I can have simvision render different types of transactions with different colors e.g. based on a transaction attribute. I know how to do it at signal level using mnemonics but I haven't succeeded doing this at transaction level. Anyone?
