Few cycle pulse propagation [PDF]

, 2002
We present a comprehensive framework for treating the nonlinear interaction of few-cycle pulses using an envelope description that goes beyond the traditional SVEA method.

Solar cycle 25: another moderate cycle?

, 2016
Surface flux transport simulations for the descending phase of cycle 24 using random sources (emerging bipolar magnetic regions) with empirically determined scatter of their properties provide a prediction of the axial dipole moment during the upcoming ...

Odd Harmonious Labeling of P_n ⊵ C₄ and  P_n ⊵ D₂(C₄)

Indonesian Journal of Combinatorics, 2021
A graph G with q edges is said to be odd harmonious if there exists an injection f:V(G) → ℤ2q so that the induced function f*:E(G)→ {1,3,...,2q-1} defined by f*(uv)=f(u)+f(v) is a bijection.Here we show that graphs constructed by edge comb product of ...

Life-cycle of fatigue sensitive structures under uncertainty [PDF]

, 2013
Fatigue is the one of the main contributors to problems related to structural safety of civil and marine structures. Life-cycle management (LCM) techniques considering various uncertainties can be used to predict the safe service life of fatigue ...

Cycle structure of random permutations with cycle weights

, 2012
We investigate the typical cycle lengths, the total number of cycles, and the number of finite cycles in random permutations whose probability involves cycle weights.

A Quality Improvement Initiative to Standardize Pneumocystis jirovecii Pneumonia Prophylaxis in Pediatric Patients With Solid Tumors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric patients with extracranial solid tumors (ST) receiving chemotherapy are at an increased risk for Pneumocystis jirovecii pneumonia (PJP). However, evidence guiding prophylaxis practices in this population is limited. A PJP‐related fatality at our institution highlighted inconsistent prescribing approaches and concerns about

Biomasa: alternativa energética para la reducción de emisiones atmosféricas

Lámpsakos, 2020
La biomasa produce la misma cantidad de emisiones de dióxido de carbono que absorbe durante su crecimiento, es decir, solo emite la misma cantidad de CO2 que procesa durante parte de su ciclo de vida, haciéndola neutra en cuanto a sus emisiones de ...
