The P–T–X conditions of staurolite-garnet metabasites, NW Iran: Implications for metamorphism during Arabia-Eurasia collision

open access: yesJournal of Asian Earth Sciences: X
The staurolite-bearing Avajiq metabasites (AMB) crop out near the NW border of Iran with Turkey and contain the peak assemblage garnet + Ca-amphibole + staurolite + biotite + chlorite1 + ilmenite. The AMB record peak pressure–temperature (P-T) conditions

Provider and Parent Perspectives on Prioritizing the “Asking and Monitoring” Pediatric Cancer Psychosocial Standards of Care

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The Standards for Psychosocial Care for Children with Cancer and Their Families (“Standards”) are evidence‐based guidelines for psychosocial care in pediatric oncology. Care related to the three “Asking and Monitoring” Standards—Assessment of Psychosocial Needs, Assessment of Financial Needs, and Monitoring Neurocognitive Problems ...

High p–T Conditions as a Route to Multicomponent High‐Entropy Nitrides

open access: yesSmall Structures
Laser‐heated diamond anvil cells with in situ synchrotron X‐ray diffraction were used to study the reaction of nitrogen with a Ti40Zr20Nb20Hf5Ta15 at% high‐entropy alloy at ∼2500 K and under a pressure of ∼32 GPa.

P–T conditions of anthophyllite- and garnet-bearing metapelites of the Nunatarsuaq domain, Nagssugtoqidian orogen, West Greenland

open access: yesGEUS Bulletin
Anthophyllite- and garnet-bearing metapelites from the Nunatarsuaq domain, located north of the UNESCO World Heritage site Ilulissat Icefjord (Kangiata Sullua) in Greenland at the northern margin of the Nagssugtoqidian orogen, enable a first quantitative

About sign-constancy of Green's functions for impulsive second order delay equations [PDF]

open access: yesOpuscula Mathematica, 2014
We consider the following second order differential equation with delay \[\begin{cases} (Lx)(t)\equiv{x''(t)+\sum_{j=1}^p {b_{j}(t)x(t-\theta_{j}(t))}}=f(t), \quad t\in[0,\omega],\\ x(t_j)=\gamma_{j}x(t_j-0), x'(t_j)=\delta_{j}x'(t_j-0), \quad j=1,2 ...

Safety and Effectiveness of a High‐Dose, Tailored Tissue Plasminogen Activator Therapy Protocol: A Joint Pediatric Hematology and Cardiac ICU Quality Improvement Initiative Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA

Oscillation in second order functional equations with deviating arguments

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1981
For the pair of functional equations (A)(r(t)y′(t))+p(t)h(h(g(t)))=f(t) and (B)(r(t)y′(t))−p(t)h(y(g(t)))=0 sufficient conditions have been found to cause all solutions of equation (A) to be oscillatory.

About sign-constancy of Green’s function of a two-point problem for impulsive second order delay equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We consider the following second order differential equation with delay $$ \begin{cases} \begin{split} (Lx)(t)&\equiv{x''(t)+\sum_{j=1}^p {a_{j}(t)x'(t-\tau_{j}(t))}+\sum_{j=1}^p {b_{j}(t)x(t-\theta_{j}(t))}}=f(t), & t\in[0,\omega] \end{split} \\ x(t_k)=

Measurement of the top quark p(T) distribution [PDF]

open access: yes, 2001
We have measured the p(T) distribution of top quarks that are pair produced in p (p) over bar collisions at roots = 1.8 TeV using a sample of t (t) over bar decays in which we observe a single high-P-T charged lepton, a neutrino, and four or more jets ...
