The Complexity of Order Type Isomorphism

open access: yes, 2013
The order type of a point set in $R^d$ maps each $(d{+}1)$-tuple of points to its orientation (e.g., clockwise or counterclockwise in $R^2$). Two point sets $X$ and $Y$ have the same order type if there exists a mapping $f$ from $X$ to $Y$ for which ...

Potential neuroprotective and therapeutic agents and their mechanisms for irradiation‐induced brain injury

open access: yesIbrain, EarlyView.
In this review, agents such baicalein, troxerutin, epigallocatechin gallate, quercetin, melatonin, valproic acid, lithium, neurosteroid progesterone, as well as minocycline have been implicated as neuroprotective agents for irradiation‐induced neurological deficits. Also, agents such as glucocorticoids, methylphenidate, vitamin E, bisdemethoxycurcumin,

Disentangling the Determinants of Successful Demobilization and Reintegration [PDF]

open access: yes
Since 1989, international efforts to end protracted conflicts in Africa, Latin America, and Asia have included sustained investments in the disarmament, demobilization, and reintegration (DDR) of combatants from the warring parties.

Exploring the Clinical Potential of Dynamic Digital Radiography: A Narrative Review

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Dynamic Digital Radiography (DDR) is a promising X‐ray technology that captures rapid image sequences, enabling the visualisation of moving anatomical structures for various clinical applications, including pulmonary, cardiac and orthopaedic assessments.

Arylkationen als mögliche Zwischenprodukte bei der Blitzlichtphotolyse von Aryldiazoniumsalzen in wäßriger Lösung

open access: yesCHIMIA, 1973
Evidence is presented by means of flash photolysis experiments that aryl cations are real intermediates in the photolysis of para substituted aryldiazonium salts (Et2N, OMe, Cl, NO2) in aqueous solution.

Active Learning for the Discovery of Antiviral Polymers

open access: yesMacromolecular Rapid Communications, EarlyView.
Machine learning and active learning are integrated to accelerate the discovery of antiviral polymers. Molecular descriptors derived from polymer composition enable predictive modeling of antiviral activity, while unsupervised clustering explores chemical diversity. The active learning workflow identifies optimal candidates for synthesis, demonstrating

Was bleibt von der Geschichtswissenschaft der DDR?

open access: yesÖsterreichische Zeitschrift für Geschichtswissenschaften, 1991
In this article the development of East German historiography is outlined and its author, a leading social historian of the former GDR, poses the question what is worth continuing from this historiographic tradition.

Fixed points and their stability in the functional renormalization group of random field models

open access: yes, 2013
We consider the zero-temperature fixed points controlling the critical behavior of the $d$-dimensional random-field Ising, and more generally $O(N)$, models.
