INTRODUCTION Intravascular volume status is an important clinical consideration in the management of the critically ill. Point-of-care ultrasonography (POCUS) has gained popularity as a non-invasive means of intravascular volume assessment via examination of the inferior vena cava (IVC). However, there are limited data comparing different acquisition techniques for IVC measurement by POCUS. The...

We report on a bendable photonic crystal fiber for short pulse high power fiber laser applications. This fiber uses a double lattice structure and enables single mode operation with a very large mode area that reaches 1454 µm² when the fiber is kept straight and 655 µm² in the fiber bent around a 10 cm radius. Single mode operation is enforced by the very large bending loss in excess of 50 dB/m...

S U M M A R Y We show that higher modes are an important component of high-frequency Rayleigh waves in the cross-correlations over sedimentary basins. The particle motions provide a good test for distinguishing and separating the fundamental from the first highermode, with the fundamental mode having retrograde and the first higher mode having prograde motion in the 1–10 s period of interest. T...

In a coalescing neutron star-neutron star or neutron star-black hole binary, oscillation modes of the neutron star can be resonantly excited by the companion during the final minutes of the binary inspiral, when the orbital frequency sweeps up from a few Hertz to a few thousand Hertz. The resulting resonant energy transfer between the orbit and the neutron star speeds up or slows down the inspi...

This paper introduces four new resistorless circuits of first-order current-mode all-pass filter (CMAPF) based on dual-X current conveyor transconductance amplifier (DXCCTA). All the four circuits use a single DXCCTA and a capacitor for their realization. The main features of the proposed CMAPFs are: use of minimum active and passive components, resistorless realization, electronically adjustab...

We propose a block-cipher mode of operation, EAX, for authenticated-encryption with associateddata (AEAD). Given a nonce N , a message M , and a header H, the mode protects the privacy of M and the authenticity of both M and H. Strings N, M, H E {0, 1} are arbitrary, and the mode uses 2→M/n∈ + →H/n∈ + →N/n∈ block-cipher calls when these strings are nonempty and n is the block length of the unde...

At present, bone marrow analysis is performed microscopically, but is time consuming and labour intensive. No automated methods have been successfully applied to classification of bone marrows cells because automated blood cell analysers have been incapable of identifying erythroblasts. The present study was designed to evaluate automated analysis of bone marrow aspirates with the CELL-DYN 4000...

In this paper we present the fabrication of optical mode field adaptors for fiber optical communications using fiber splicing machine in special newly developed modus. We developed mode field transformers with radii from 5 m to 80 m the end of standard singlemode and multimode glass fibers, characterized by far field and near field methods. Easy and reliable fabrication of the radii with low st...

The aim of this paper is to propose a natural definition of a winding number for a m-note mode, generalizing the concept of well formedness (proposed by Carey and Clampitt) providing and discussing some aspects regarding the Stern-Brocot trees. We start by giving an algebraic definition of a m-notes mode in a chromatic set of n elements as a composed map between Zm and Zn. Then we introduce the...
