We present a series of detailed band calculations on the various structural phases of doped lanthanum cuprate: HTT, LTO, and LTT. The LTO distortion is shown to have little effect on the electronic density of states (DOS). A fit to the pressure dependence of the superconducting transition temperature indicates that only 2.5% of the DOS is affected by the HTT→ LTO transition. The LTT distortion ...

Denial of service Attacks have become one of the most common ways to attack a system. Numerous recent incidents have proved that even carefully designed systems (e.g. large scale web servers) can be brought down by a DoS attack. This is mainly because today, there are no wide spread and well established mechanisms to detect DoS attacks and give the servers appropriate notice. Many ongoing resea...

The transition metal (TM)-absorbed germanene systems enriched by strong chemical bonding are investigated using first-principles calculations. Dedicated calculations include the geometry, preferable adsorption sites, atom-dominated band structure, spin–density distributions, spatial charge distribution, and projected density of states (DOS). multi-orbital bonds between TMs Ge atoms can create s...

Dissolved organic sulfur (DOS) is the largest pool of organic sulfur in the oceans, and as such it is an important component of the global sulfur cycle. DOS in the ocean is resistant against microbial degradation and turns over on a millennium time scale. However, sources and mechanisms behind its stability are largely unknown. Here, we hypothesize that in sulfate-reducing sediments sulfur is a...

The Denial of Service (DoS) attacks pose a major threat to Internet users and services. Since the network security ecosystem is expanding over the years, new types of DoS attacks emerge. The DoS link-flooding attacks target to severely congest certain network links disrupting Internet accessibility to certain geographical areas and services passing through these links. Since crucial services li...

We present a quantitative comparison of lipid and water signals obtained from broadband Diffuse Optical Spectroscopy (DOS) and Magnetic Resonance Imaging (MRI). DOS and MRI measurements were performed on an identical set of emulsion phantoms that were composed of different water/soybean oil fractions. Absolute concentrations of water and lipid ranging from 35-94% and 63-6%, respectively were ca...

ON MODELING AND MITIGATING NEW BREED OF DOS ATTACKS by Amey Bhaskar Shevtekar Denial of Service (DoS) attacks pose serious threats to the Internet, exerting in tremendous impact on our daily lives that are heavily dependent on the good health of the Internet. This dissertation aims to achieve two objectives: 1) to model new possibilities of the low rate DoS attacks; 2) to develop effective miti...

Purpose:Diffuse optical spectroscopy (DOS) has the potential to enable monitoring of tumor response during chemotherapy, particularly in the early stages of treatment. This study aims to assess feasibility of DOS for monitoring treatment response in HER2-negative breast cancer patients receiving neoadjuvant chemotherapy (NAC) and compareDOSwith tumor response assessment by MRI. Experimental Des...

This research suggests a Denial of Service (DoS) detection method based on the collection of interdependent behavior data in a sensor network environment. In order to collect the interdependent behavior data, we use a base station to analyze traffic and behaviors among nodes and introduce methods of detecting changes in the environment with precursor symptoms. The study presents a DoS Detection...
