Manufacturing Nostalgia in the Digital Age: A Foreverism Perspective

open access: yesPsychology &Marketing, EarlyView.
ABSTRACT Many scholars argue that we are experiencing the era of “retro”—nostalgia‐driven marketing and consumption phenomena reinforced by digital technologies. However, existing research lacks a critical analysis of nostalgia in contemporary markets and of how digital content, tools, and environments transform retro consumption experiences and alter ...

Living with the Unknown: Intolerance of Uncertainty in Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Parkinson's disease (PD) is marked by pervasive uncertainty due to fluctuating motor and non‐motor symptoms, variable treatment response, and an unpredictable clinical course. Intolerance of uncertainty (IU), a tendency to perceive ambiguity as threatening and respond with worry, avoidance, or decisional paralysis, may be ...

Asking Fast Radio Bursts for More than Reionization History

open access: yesThe Astrophysical Journal
We propose different estimators to probe the intergalactic medium (IGM) during the epoch of reionization (EoR) using the dispersion measure (DM) of the fast radio bursts. We consider three different reionization histories, which we can distinguish with a

Navigating challenges: Diagnosis and management of foreign body aspiration in a child: A case report

open access: yesJournal of Family Medicine and Primary Care
Foreign body aspiration in pediatric patients presents a significant challenge in diagnosis and management, often leading to acute respiratory distress. We report the case of a 4-and-a-half-year-old male child with a history of recurrent left-sided lobar

Effective Modeling of Continuous Wave Z$$ Z $$‐Spectra for Quantitative CEST and CESL MRI Across Exchange Regimes

open access: yesMagnetic Resonance in Medicine, EarlyView.
Purpose Chemical exchange saturation transfer (CEST) and chemical exchange‐sensitive spin‐lock (CESL) MRI enable spectroscopic imaging with high sensitivity, but conventional analysis methods often fail as exchange approaches the fast‐exchange limit.

Toy observer in unitary evolution: Histories, consciousness, and state reduction

open access: yes, 2014
For a toy version of a quantum system with a conscious observer, it is demonstrated that the many-worlds problem is solved by retreating into the conscious subspace of an entire observer history. In every step of a discretised time, the observer tries to "see" records of his past and present in a coherent temporal sequence, by scanning through a ...

Multi‐Contrast Human Brain CEST MRI at 11.7 T: First In Vivo Demonstration

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT PurposeTo implement and evaluate chemical exchange saturation transfer (CEST) at ultra‐high field on a whole‐body 11.7 T scanner using parallel transmission (pTx). MethodsTailored pTx CEST saturation pulses were optimized to achieve a spatially uniform target B1+ while satisfying SAR and power constraints either defined by conservatively ...

A Generalized Approach to Solving Deep Learning‐Based Quantitative Susceptibility Mapping and Quantitative Blood Oxygen Level Dependent Magnitude (QSM + qBOLD or QQ) for Oxygen Extraction Fraction (OEF) Mapping Across Diverse Acquisition Schemes

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose QQ, a recently proposed oxygen extraction fraction (OEF) mapping technique combining quantitative susceptibility mapping (QSM) and quantitative blood oxygen level‐dependent (qBOLD) (QSM + qBOLD = QQ), generates OEF maps noninvasively from a single routine MRI sequence, without requiring vascular challenges used in other OEF approaches.

Quantum-Informational History Optimization Theory (QIHOT): A Single-History Selection Framework with Consistency Results

open access: yesQuantum Reports
We present Quantum-Informational History Optimization Theory (QIHOT) as a formal proposal for selecting a single realized quantum history from a space of dynamically admissible histories subject to boundary constraints.

Allocation of Indivisible Items With a Common Preference Graph: Minimizing Total Dissatisfaction

open access: yesNetworks, EarlyView.
ABSTRACT Allocating indivisible items among a set of agents is a frequently studied discrete optimization problem. In the setting considered in this work, the agents' preferences over the items are assumed to be identical. We consider a very recent measure for the overall quality of an allocation which does not rely on numerical valuations of the items.
