Dark Matter from Early Decays

open access: yes, 2005
Two leading dark matter candidates from supersymmetry and other theories of physics beyond the standard model are WIMPs and weak scale gravitinos. If the lightest stable particle is a gravitino, then a WIMP will decay into it with a natural lifetime of ...

A coupled thermal and electrochemical study of lithium-ion battery cooled by paraffin/porous-graphite-matrix composite [PDF]

open access: yes, 2016
Lithium-ion (Li-ion) battery cooling using a phase change material (PCM)/compressed expanded natural graphite (CENG) composite is investigated, for a cylindrical battery cell and for a battery module scale.

Kaon-Nucleon Scattering Amplitudes and Z$^*$-Enhancements from Quark Born Diagrams [PDF]

open access: yes, 1992
We derive closed form kaon-nucleon scattering amplitudes using the ``quark Born diagram" formalism, which describes the scattering as a single interaction (here the OGE spin-spin term) followed by quark line rearrangement.

Constraints on hidden gravitons from fifth-force experiments and stellar energy loss [PDF]

open access: yes, 2017
We study different phenomenological signatures associated with new spin-2 particles. These new degrees of freedom, that we call hidden gravitons, arise in different high-energy theories such as extra-dimensional models or extensions of General Relativity.

Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

open access: yesAdvanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

The OpenMOC method of characteristics neutral particle transport code [PDF]

open access: yes, 2013
The method of characteristics (MOC) is a numerical integration technique for partial differential equations, and has seen widespread use for reactor physics lattice calculations.

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

open access: yesAdvanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

What can we learn from Dijet suppression at RHIC?

open access: yes, 2012
We present a systematic study of the dijet suppression at RHIC using the VNI/BMS parton cascade. We examine the modification of the dijet asymmetry A_j and the within-cone transverse energy distribution (jet-shape) along with partonic fragmentation ...

GenEvA (II): A phase space generator from a reweighted parton shower [PDF]

open access: yes, 2008
We introduce a new efficient algorithm for phase space generation. A parton shower is used to distribute events across all of multiplicity, flavor, and phase space, and these events can then be reweighted to any desired analytic distribution.

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes

open access: yesAdvanced Materials, EarlyView.
A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.
