Single-shot quantum memory advantage in the simulation of stochastic processes

open access: yes, 2018
Stochastic processes underlie a vast range of natural and social phenomena. Some processes such as atomic decay feature intrinsic randomness, whereas other complex processes, e.g.

The Role of Operating Temperature on Pore‐Scale Gas Transport in Polymer Electrolyte Membrane Electrolyzers

open access: yesAdvanced Science, Volume 12, Issue 44, November 27, 2025.
This study clarifies the critical relationship between operating temperature and two‐phase flow behavior in polymer electrolyte membrane (PEM) electrolyzers by investigating pore‐scale gas bubble transport in the anode porous transport layer. Higher temperatures (80 °C vs 40 °C) result in a lower total bubble volume fraction and smaller bubble ...

Medsebojna podpora partnerjev v procesu žalovanja po otrokovi smrti

open access: yesPsihološka Obzorja, 2015
Smrt bližnje osebe je ena najtežjih situacij, s katero se posameznik sooča večkrat v življenju. Za starše je zelo stresna otrokova smrt. Takrat je zelo pomembna medsebojna podpora partnerjev, ki jim je lahko v pomoč ali pa je vir stresa in je pomembno ...

Optimal arbitrarily accurate composite pulse sequences

open access: yes, 2014
Implementing a single qubit unitary is often hampered by imperfect control. Systematic amplitude errors $\epsilon$, caused by incorrect duration or strength of a pulse, are an especially common problem.

Pogostost simptomov depresivnosti med gimnazijci

open access: yesPsihološka Obzorja, 2002
Na vzorcu 180 dijakov (90 fantov, 90 deklet) kočevske gimnazije smo raziskovali pogostost simptomov depresivnosti med gimnazijci ter vpliv spola, učne uspešnosti in starosti na pojavljanje depresivnega reagiranja.

Tracking Floating Wood During a Flood: New Insights From Drone Surveys and Machine Learning

open access: yesJournal of Geophysical Research: Earth Surface, Volume 130, Issue 11, November 2025.
Abstract Instream large wood (LW) plays a vital role in river morphology and ecology, but its transport can pose risks to infrastructure during floods. Monitoring LW transport during flood events remains limited due to technical and logistical limitations.

Osebnost in motivacija športnikov in športnic

open access: yesPsihološka Obzorja, 2003
V raziskavi so nas zanimale razlike v osebnostni in motivacijski strukturi pri vrhunskih športnikih in športnikih in med športniki in športnicami, preverjali pa smo tudi interakcijski učinek športne uspešnosti in spola.

Modifying Faug\`ere's F5 Algorithm to ensure termination [PDF]

open access: yes, 2010
The structure of the F5 algorithm to compute Gr\"obner bases makes it very efficient. However, while it is believed to terminate for so-called regular sequences, it is not clear whether it terminates for all inputs. This paper has two major parts. In the

On the Complexity of the Generalized MinRank Problem

open access: yes, 2013
We study the complexity of solving the \emph{generalized MinRank problem}, i.e. computing the set of points where the evaluation of a polynomial matrix has rank at most $r$.
