Proton Decay and the Planck Scale

open access: yes, 2004
Even without grand unification, proton decay can be a powerful probe of physics at the highest energy scales. Supersymmetric theories with conserved R-parity contain Planck-suppressed dimension 5 operators that give important contributions to nucleon ...

PairTilt: Design and Control of an Active Tilt‐Rotor Quadcopter for Improved Efficiency and Agility

open access: yesAdvanced Intelligent Systems, EarlyView.
PairTilt is an actuated tilt‐rotor unmanned aerial vehicle capable of active shape reconfiguration, balancing simplicity, efficiency, and agility. Its H‐shaped frame incorporates pairwise tiltable rotors, which reduce gyroscopic torque and decouple key dynamics, enhancing maneuverability and reducing drag.

Fairness in Federated Learning: Trends, Challenges, and Opportunities

open access: yesAdvanced Intelligent Systems, EarlyView.
This survey delves into the intricate issues pertinent to fairness in federated learning , where various biasing factors can skew model performance. By systematically analyzing fairness‐aware strategies, evaluation metrics, and future directions, this work identifies pivotal research gaps in existing approaches and sheds light on both challenges and ...

A note on the birefringence angle estimation in CMB data analysis

open access: yes, 2016
Parity violating physics beyond the standard model of particle physics induces a rotation of the linear polarization of photons. This effect, also known as cosmological birefringence (CB), can be tested with the observations of the cosmic microwave ...

Topics of Interest in Women With Myeloproliferative Neoplasms

open access: yesAmerican Journal of Hematology, EarlyView.
Women with MPN: life‐cycle phases, specific risks, and influencing factors. ABSTRACT Overview Sex and gender have emerged as central modifiers of disease biology, phenotype, and clinical outcomes in myeloproliferative neoplasms (MPNs). This review will uniquely highlight issues affecting women with MPN and articulate their relevant determinants ...

A comparative study of 0νββ decay in symmetric and asymmetric left-right model

open access: yesNuclear Physics B, 2020
We study the new physics contributions to neutrinoless double beta decay (0νββ) in a TeV scale left-right model with spontaneous D-parity breaking mechanism where the values of the SU(2)L and SU(2)R gauge couplings, gL and gR are unequal.

Testing non-standard sources of parity violation in jets at the LHC, trialled with CMS Open Data

open access: yesJournal of High Energy Physics, 2019
The Standard Model violates parity, but only by mechanisms which are invisible to Large Hadron Collider (LHC) experiments (on account of the lack of initial state polarisation or spin-sensitivity in the detectors).

Search for new phenomena with large jet multiplicities and missing transverse momentum using large-radius jets and flavour-tagging at ATLAS in 13 TeV pp collisions

open access: yesJournal of High Energy Physics, 2017
A search is presented for particles that decay producing a large jet multiplicity and invisible particles. The event selection applies a veto on the presence of isolated electrons or muons and additional requirements on the number of b-tagged jets and ...

Search for Fingerprints of Tetrahedral Symmetry in $^{156}Gd$

open access: yes, 2008
Theoretical predictions suggest the presence of tetrahedral symmetry as an explanation for the vanishing intra-band E2-transitions at the bottom of the odd-spin negative parity band in $^{156}Gd$.
