Vector-Circulant Matrices over Finite Fields and Related Codes [PDF]

arXiv, 2014
A vector-circulant matrix is a natural generalization of the classical circulant matrix and has applications in constructing additive codes. This article formulates the concept of a vector-circulant matrix over finite fields and gives an algebraic characterization for this kind of matrix.

Global Solution of Atmospheric Circulation Models with Humidity Effect [PDF]

arXiv, 2014
The atmospheric circulation models are deduced from the very complex atmospheric circulation models based on the actual background and meteorological data. The models are able to show features of atmospheric circulation and are easy to be studied. It is proved that existence of global solutions to atmospheric circulation models with the use of the $T ...

Henri Lefebvre and the spatial revolution that never ends: Towards the reconciliation of anarchist and Marxist approaches in geography?

Transactions of the Institute of British Geographers, EarlyView.
Abstract It is widely accepted that Henri Lefebvre's Marxism had anarchistic traits, but few have tried to specify what these traits are, or what they mean. This paper argues that Lefebvre's work should be seen as first and foremost an anti‐authoritarian theory that uses space, rather than a spatial theory.

Running on empty: Factors underpinning impaired cardiac output reserve in heart failure with preserved ejection fraction

Experimental Physiology, EarlyView.
Abstract Heart failure with preserved ejection fraction (HFpEF) is frequently attributed etiologically to an underlying left ventricular (LV) diastolic dysfunction, although its pathophysiology is far more complex and can exhibit significant variations among patients. This review endeavours to systematically unravel the pathophysiological heterogeneity

Many-Shot Regurgitation (MSR) Prompting [PDF]

arXiv
We introduce Many-Shot Regurgitation (MSR) prompting, a new black-box membership inference attack framework for examining verbatim content reproduction in large language models (LLMs). MSR prompting involves dividing the input text into multiple segments and creating a single prompt that includes a series of faux conversation rounds between a user and ...

Prolonged postnatal adaptation and enhanced prevalence of congenital heart diseases due to altitude may contribute to newborn mortality in Bolivia

Experimental Physiology, EarlyView.
Abstract Highland populations suffer from significant infant mortality due to chronic ambient hypoxia, which increases the risk of congenital heart disease (CHD) and neonatal pulmonary hypertension. Neither the prevalence of these conditions nor the effectiveness of neonatal cardiac screening to identify CHD or pulmonary hypertension among neonates ...

Investigating the shortcomings of the Flow Convergence Method for quantification of Mitral Regurgitation in a pulsatile in-vitro environment and with Computational Fluid Dynamics [PDF]

arXiv
The flow convergence method includes calculation of the proximal isovelocity surface area (PISA) and is widely used to classify mitral regurgitation (MR) with echocardiography. It constitutes a primary decision factor for determination of treatment and should therefore be a robust quantification method.

Cesarean section with operation on placental support as an adapted EXIT procedure for fetal thyroid goiter: A case report and literature review

International Journal of Gynecology &Obstetrics, Volume 169, Issue 2, Page 474-484, May 2025.
Abstract The ex‐utero intrapartum treatment (EXIT) procedure is a specialized delivery strategy that extends utero–placental–fetal circulation to convert a potential neonatal emergency condition into a condition that is compatible with postnatal life. Cesarean section with operation on placental support is an EXIT technique that requires a relatively ...

The Files are in the Computer: Copyright, Memorization, and Generative AI [PDF]

arXiv
The New York Times's copyright lawsuit against OpenAI and Microsoft alleges OpenAI's GPT models have "memorized" NYT articles. Other lawsuits make similar claims. But parties, courts, and scholars disagree on what memorization is, whether it is taking place, and what its copyright implications are.
