Belowground interactions differ between sympatric desert shrubs under water stress
Ecology and Evolution, 2020 Understanding the relationships among species is central to ecological research; however, many knowledge gaps remain regarding how desert plant species interact. In the present study, we assessed the effect of rainfall on the belowground interactions and

Optimal random search for a single hidden target
, 2010 A single target is hidden at a location chosen from a predetermined probability distribution. Then, a searcher must find a second probability distribution from which random search points are sampled such that the target is found in the minimum number of ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

Simulating Root Density Dynamics and Nitrogen Uptake – Can a Simple Approach be Sufficient? [PDF]
, 2007 The modeling of root growth in many plant–soil models is simple and with few possibilities to adapt simulated root proliferation and depth distribution to that actually found with different crop species.

On the distribution of primitive roots mod p [PDF]
Acta Arithmetica, 1998 Let \(p\) be a large prime number and consider the set of primitive roots mod \(p\) with representatives \(1 < \gamma_1 < \cdots < \gamma_{\varphi(p-1)} < p\). The authors show that, if \(\varphi(p-1)/p\) is small, then the distribution of the number of \(\gamma\)'s in the interval \((n,n+t]\), \(1 \leq n \leq p\), where \(t \sim \lambda p/ \varphi(p-1)

Pediatric Blood &Cancer, EarlyView.ABSTRACT Purpose Retinoblastoma (RB) is the most common pediatric ocular cancer, yet population‐based data on survival and risk factors remain limited. This study aimed to describe survival in a large national RB cohort and identify predictors of death and complications.

Threshold stochastic unit root models [PDF]
, 2002 This paper introduces a new class of stochastic unit root (STUR) processes, where the randomness of the autorregresive unit root is driven by a threshold variable.

The influence of random element displacement on DOA estimates obtained with (Khatri-Rao-)root-MUSIC [PDF]
, 2014 Although a wide range of direction of arrival (DOA) estimation algorithms has been described for a diverse range of array configurations, no specific stochastic analysis framework has been established to assess the probability density function of the ...
