Mercury: using the QuPreSS reference model to evaluate predictive services [PDF]

open access: yes, 2017
Nowadays, lots of service providers offer predictive services that show in advance a condition or occurrence about the future. As a consequence, it becomes necessary for service customers to select the predictive service that best satisfies their needs ...

Region-based memory management for Mercury programs

open access: yes, 2012
Region-based memory management (RBMM) is a form of compile time memory management, well-known from the functional programming world. In this paper we describe our work on implementing RBMM for the logic programming language Mercury. One interesting point

Finding Minimal Cost Herbrand Models with Branch-Cut-and-Price

open access: yes, 2018
Given (1) a set of clauses $T$ in some first-order language $\cal L$ and (2) a cost function $c : B_{{\cal L}} \rightarrow \mathbb{R}_{+}$, mapping each ground atom in the Herbrand base $B_{{\cal L}}$ to a non-negative real, then the problem of finding a

The GENGA Code: Gravitational Encounters in N-body simulations with GPU Acceleration [PDF]

open access: yes, 2014
We describe an open source GPU implementation of a hybrid symplectic N-body integrator, GENGA (Gravitational ENcounters with Gpu Acceleration), designed to integrate planet and planetesimal dynamics in the late stage of planet formation and stability ...

First-order integer programming for MAP problems

open access: yes, 2015
Finding the most probable (MAP) model in SRL frameworks such as Markov logic and Problog can, in principle, be solved by encoding the problem as a `grounded-out' mixed integer program (MIP).

Description and Optimization of Abstract Machines in a Dialect of Prolog [PDF]

open access: yes, 2014
In order to achieve competitive performance, abstract machines for Prolog and related languages end up being large and intricate, and incorporate sophisticated optimizations, both at the design and at the implementation levels.

Differential Item Functioning on the Patient Health Questionnaire‐8 by Disease Subtype, Language, Sex, and Age among People with Systemic Sclerosis: A Scleroderma Patient‐centered Intervention Network Cohort Study

open access: yesArthritis Care &Research, Accepted Article.
Objective Somatic items used in depression assessments can potentially overlap with symptoms related to physical illness, including systemic sclerosis (SSc). No studies have looked at whether somatic depression items may be influenced by diffuse versus limited SSc disease subtypes, which are associated with varying degrees of symptom presentation.

The Space Within: How Architected Voids Promote Tissue Formation

open access: yesAdvanced Materials, EarlyView.
This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating

FAPα+ Macrophages Orchestrate Immune Evasion in Multiple Myeloma by Dual Regulation of PD‐L1 and T Cell Senescence

open access: yesAdvanced Science, EarlyView.
ABSTRACT Multiple myeloma (MM) is a hematologic malignancy driven by clonal expansion of malignant plasma cells. Despite the long‐term disease control achieved with immunotherapies in some patients, treatment resistance remains a major cause of disease relapse.
