1990s Strength in numbers Karrera Djoko (top) was 12 years old when her life uprooted. To avoid racial unrest Indonesia, family relocated to Singapore. Among the many adjustments of moving a new country, Djoko’s classes were now taught English. Because she still learning language, drawn toward subjects that based more on numbers. “Life kind steered me towards math and science,” says. Her parent...

We present a new type of attack termed denial of engineering operations in which an attacker can interfere with the normal cycle of an engineering operation leading to a loss of situational awareness. Speci cally, the attacker can deceive the engineering software during attempts to retrieve the ladder logic program from a programmable logic controller (PLC) by manipulating the ladder logic on t...

A ladder-shaped array is a subset of a rectangular array which looks like a Ferrers diagram corresponding to a partition of a positive integer. The ideals generated by the p-by-p minors of a ladder-type array of indeterminates in the corresponding polynomial ring have been shown to be hilbertian (i.e., their Hilbert functions coincide with Hilbert polynomials for all nonnegative integers) by Ab...

Loading/unloading a ladder on vehicles are frequent tasks and involve overhead handling that may expose workers to risk factors of shoulder musculoskeletal disorders. The objective of the present study was to evaluate posture, forces required and perceived exertion when loading and unloading the ladder on a utility truck. Thirteen male overhead line workers from an electric utility in Brazil pa...

We present the Raman scattering spectra of CaV 2 O 5 and MgV 2 O 5. Our analysis of the magnetic modes shows that the magnetic ordering in CaV 2 O 5 can be described using two-leg ladder Heisenberg antiferromagnetic model with J /J ⊥ ∼ 0.1, and a small interladder exchange. The spin-gap and exchange constant are estimated to be ∆ s ∼ 400 cm −1 (570 K) and J ⊥ ∼ 640 K. No magnon bound states are...

The purpose of this study was to measure undergraduate students' knowledge of social determinants of health, health equity, and subjective social status (SSS). A cross-sectional semi-structured survey was administered to 68 racially/ethnically diverse freshman students enrolled in a baccalaureate nursing program in O'ahu, Hawai'i. Students ranked the impact of 13 issues on Hawai'i residents' he...

INTRODUCTION A growing interest in apoptosis, programmed cell death, in the last years is observed and leads to better understanding of molecular mechanisms during cell-cell signaling, cell-environment interaction and screening of drugs. This in turn results in emerging of new assays and development of more accurate kits for fast and early detection of apoptosis. However, their sensitivity and ...

We consider the small field asymptotics of the ladder lifetime for a single ladder model. Using the convergent perturbation series, we prove that the behavior of the lifetime computed by means of the Fermi Golden Rule is proportional to the correct one with the factor ( π 3 )2 . The relation with usual adiabatic problems is briefly discussed.

We show the light-front representation of the field theoretical Bethe-Salpeter equation (BSE) in the ladder approximation using the quasi potential reduction. We discuss the equivalence of the covariant ladder Bethe-Salpeter equation with an infinite set of coupled equations for the Green’s functions of the different light-front Fock-states.
