Hierarchical testing designs for pattern recognition

, 2005
We explore the theoretical foundations of a ``twenty questions'' approach to pattern recognition. The object of the analysis is the computational process itself rather than probability distributions (Bayesian inference) or decision boundaries ...

Critical point drying of brain tissue for X‐ray phase‐contrast imaging

Journal of Synchrotron Radiation, EarlyView.
X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.

Wideband Channel Estimation and Prediction in Single-Carrier Wireless Systems

, 2005
—In this contribution wideband channel estimation and prediction designed for single-carrier wideband wireless communications systems are investigated. Specifically, the single-carrier wideband pilot signal received by the receiver is first converted to ...

High Resolution Ionization of Ultracold Neutral Plasmas

, 2011
Collective effects, such as waves and instabilities, are integral to our understanding of most plasma phenomena. We have been able to study these in ultracold neutral plasmas by shaping the initial density distribution through spatial modulation of the ...

pseyfert/35c3-ctf-writeup

, 2018
At the [35C3](https://events.ccc.de/congress/2018/wiki/index.php/Main_Page), there was once again a capture the flag challenge. From last year's experience, I directly went to the [junior version](https://junior.35c3ctf.ccc.ac/announcements/1/) and tried my luck. This is the writeup of my solutions.

BIEN: A biodiversity informatics ecosystem advancing open and reproducible workflows for plant observation, plot and trait data

Methods in Ecology and Evolution, EarlyView.
Abstract The rapid expansion of biodiversity data presents new opportunities to understand and forecast biosphere dynamics. However, disparate and dispersed data, taxonomic and geographic inconsistencies, pervasive quality issues, and a lack of reproducable workflows hinder synthesis, introduce biases and limit accurate assessment of biodiversity ...

Increased Risk for Liver Disease in Patients With Chronic Hepatitis B Virus Infection and Low‐Level Viraemia

Alimentary Pharmacology &Therapeutics, EarlyView.
We used an administrative claims dataset to evaluate the relationship between hepatitis B virus (HBV) low‐level viraemia and subsequent liver‐related outcomes in patients with chronic HBV. We found that individuals with HBV low‐level viraemia have an increased risk for liver‐related events (i.e., cirrhosis, decompensation, and hepatocellular carcinoma)

VCSELs with Stable Linear Polarization Emission Induced by Dielectric Columnar Thin Film Mirrors

Photonics
We propose and analyze numerically new approaches to force the laser emission from VCSELs in a well-defined linear polarization independent of the existing phase and amplitude anisotropies by using dielectric columnar thin-film (CTF) layers in the ...

Associations between TMEM106B C‐terminal fragment aggregation, age, and TDP‐43 or tau pathology

Brain Pathology, EarlyView.
TMEM106B C‐terminal fragment (CTF) aggregation represents an age‐associated, common, diffuse phenomenon emerging after midlife with a weak association with TDP‐43 or tau pathology. These findings suggest that TMEM106B fibrillization may define a distinct axis of protein aggregation in the aging human brain. Abstract Transmembrane protein 106B (TMEM106B)
