First observation of de Broglie-Mackinnon wave packets achieved by exploiting loophole in 1980s theorem

Posted by in category: physics

University of Central Florida College of Optics and Photonics researchers achieved the first observation of de Broglie-Mackinnon wave packets by exploiting a loophole in a 1980s-era laser physics theorem.

The by CREOL and Florida Photonics Center of Excellence professor Ayman Abouraddy and research assistant Layton Hall has been published in the journal Nature Physics.

Observation of optical de Broglie–Mackinnon wave packets highlights the team’s research using a class of pulsed laser beams they call space-time wave packets.

US IRS wants everyone to declare if they engage in crypto

Posted by in category: futurism

The Internal Revenue Service (IRS), responsible for enforcing federal tax laws in the United States, recently published a list of reporting obligations for the general public regarding cryptos as the time for filing the 2022 federal income tax return draws near.

Since “virtual money” is a term that is no longer used for income tax purposes as of 2021, the IRS changed the phrase to “digital assets.” All US citizens must answer all crypto-related questions, irrespective of their activity.

The question about digital asset income appears on three different tax forms, specifically in the 1040 Individual Income Tax Return, the 1040-SR US Tax Return for Seniors, and the 1040-NR US Nonresident Alien Income Tax Return.

This Physicist Says Electrons Spin in Quantum Physics After All. Here’s Why

Posted by in categories: mathematics, particle physics, quantum physics, space

‘Spin’ is a fundamental quality of fundamental particles like the electron, invoking images of a tiny sphere revolving rapidly on its axis like a planet in a shrunken solar system.

Only it isn’t. It can’t. For one thing, electrons aren’t spheres of matter but points described by the mathematics of probability.

But California Institute of Technology philosopher of physics Charles T. Sebens argues such a particle-based approach to one of the most accurate theories in physics might be misleading us.

These scientists used CRISPR to put an alligator gene into catfish

Posted by in category: biotech/medical

These scientists seem to be enjoying themselves. 🤣

They just want stronger more disease free fish.


The resulting fish appear to be more resistant to disease and could improve commercial production—should they ever be approved.

Determinants of escapism in adult video gamers with autism spectrum conditions: The role of affect, autistic burnout, and gaming motivation

Posted by in categories: biotech/medical, entertainment, neuroscience

😉


Persons with autism spectrum conditions (ASC) often engage in video gaming, one of the most common leisure activity in this population. Escapism, aimed at the avoidance of negative experiences or self-development, is considered as one of the main gaming motivations. Furthermore, escapism is a self-regulatory strategy used while suffering from autistic burnout, consisting of exhaustion, reduced social skills, anhedonia, and withdrawal. The goal of the current study was to determine predictors of escapism in video gaming among adult gamers with ASC. It was hypothesized that two types of escapism – self-suppression and self-expansion – would differentiate gaming motivations, affective outcomes, anhedonia, and autistic burnout rates. A total of 189 persons participated in the study (Mage = 27.52, SDage = 7.25), including 105 females. The results obtained indicated that self-suppression escapism was predicted by introjected regulation, positive and negative affect, and hedonic tone (F = 8.760, p < .001), while self-expansion was predicted by identified and integrated gaming motivations, hedonic tone, and positive affect (F = 23.066, p < .001). PLS-SEM analysis revealed good fit of the model with autistic burnout predicting self-suppression escapism. These results acknowledge the two-dimensional approach to escapism and highlight potential risk factors of self-suppression, especially among persons presenting symptoms of autistic burnout. Future research and clinical application directions are outlined.

Study uncovers a surprising level of heterogeneity in psychopathy among condemned capital murderers

Posted by in category: biotech/medical

New research sheds light on the psychological profiles of individuals who have been convicted of capital murder in California and sentenced to death. The study, published in the Journal of Forensic Sciences, found a “pronounced heterogeneity” concerning clinical psychopathy. While a substantial proportion of the offenders exhibited heightened psychopathic features, others showed no signs of psychopathy.

Psychopathy is considered important to understanding criminal behavior because it is a personality disorder characterized by a lack of empathy and remorse, along with impulsive and reckless behavior. Research has shown that individuals with psychopathic traits are overrepresented among offenders, particularly those who have committed violent or repeat offenses.

Understanding the characteristics and behaviors associated with psychopathy can aid in the prediction and prevention of criminal behavior, as well as the development of more effective treatment and rehabilitation programs for offenders.

Terahertz emission from a bounded plasma

Posted by in categories: information science, particle physics, space

The dynamics of electrons submitted to voltage pulses in a thin semiconductor layer is investigated using a kinetic approach based on the solution of the electron Boltzmann equation using particle-in-cell/Monte Carlo collision simulations. The results showed that due to the fairly high plasma density, oscillations emerge from a highly nonlinear interaction between the space-charge field and the electrons. The voltage pulse excites electron waves with dynamics and phase-space trajectories that depend on the doping level. High-amplitude oscillations take place during the relaxation phase and are subsequently damped over time-scales in the range 100 400 fs and decrease with the doping level. The power spectra of these oscillations show a high-energy band and a low-energy peak that were attributed to bounded plasma resonances and to a sheath effect. The high-energy THz domain reduces to sharp and well-defined peaks for the high doping case. The radiative power that would be emitted by the thin semiconductor layer strongly depends on the competition between damping and radiative decay in the electron dynamics. Simulations showed that higher doping level favor enhanced magnitude and much slower damping for the high-frequency current, which would strongly enhance the emitted level of THz radiation.

Kinetic modeling of laser absorption in foams

Posted by in category: particle physics

Laser interaction with foam targets is of interest for applications in the inertial confinement fusion studies and for the creation of secondary sources of energetic particles and radiation. Numerical modeling of such an interaction presents difficulties related to the sub-wavelength dimension of solid elements and high density contrast. Here, we present an analysis of laser interaction with thin wires based on the Mie theory, which demonstrates an enhanced laser absorption due to plasma resonance, and confirm this conclusion with detailed kinetic simulations. Numerical simulations also provide the characteristic time of the solid element transformation in a plasma and the energy partition between electrons and ions.

Gootkit Malware Continues to Evolve with New Components and Obfuscations

Posted by in categories: business, cybercrime/malcode

The threat actors associated with the Gootkit malware have made “notable changes” to their toolset, adding new components and obfuscations to their infection chains.

Google-owned Mandiant is monitoring the activity cluster under the moniker UNC2565, noting that the usage of the malware is “exclusive to this group.”

Gootkit, also called Gootloader, is spread through compromised websites that victims are tricked into visiting when searching for business-related documents like agreements and contracts via a technique called search engine optimization (SEO) poisoning.
