Domain-Aware Continual Zero-Shot Learning

open access: yes, 2021
We introduce Domain Aware Continual Zero-Shot Learning (DACZSL), the task of visually recognizing images of unseen categories in unseen domains sequentially. We created DACZSL on top of the DomainNet dataset by dividing it into a sequence of tasks, where

A Control Strategy for Suppressing Zero-Sequence Circulating Current in Paralleled Three-Phase Voltage-Source PWM Converters

open access: yesApplied Sciences, 2020
In microgrids, paralleled converters can increase the system capacity and conversion efficiency but also generate zero-sequence circulating current, which will distort the AC-side current and increase power losses.

On Sequences with Zero Autocorrelation and Orthogonal Designs

open access: yesJournal of Combinatorial Theory, Series A, 2001
An orthogonal design of order \(n\) and type \((s_1, s_2,\dots, s_n)\) \((s_i> 0)\), denoted \(\text{OD}(n; s_1,s_2,\dots, s_n)\), on the commuting variables \(x_1,x_2,\dots, x_n\) is an \(n\times n\) matrix \(A\) with entries in \(\{0,\pm x_1,\dots,\pm x_n\}\) such that \[ AA^T= \Biggl(\sum^n_{i=1} s_i x^2_i\Biggr) I_n.

Vision zero on fire safety

open access: yes, 2022
There is a growing interest in addressing global waste problems by applying innovative ideas and philosophies such as zero-waste and circular economy. As a new sustainability paradigm, zero-waste challenges the common assumption of waste as a valueless ...

On Sequences Without Short Zero-Sum Subsequences

open access: yesThe Electronic Journal of Combinatorics, 2023
Let $G$ be a finite abelian group. It is well known that every sequence $S$ over $G$ of length at least $|G|$ contains a zero-sum subsequence of length at most $\mathsf{h}(S)$, where $\mathsf{h}(S)$ is the maximal multiplicity of elements occurring in $S$.

On the number of Smarandache zero-divisors and Smarandache weak zero-divisors in loop rings [PDF]

open access: yes, 2005
Finding the number of Smarandache zero divisors (S-zero divisors) and Smarandache weak zero divisors (S-weak zero divisors) for the loop ...

Zero range condensation at criticality [PDF]

open access: yes, 2011
Zero-range processes with decreasing jump rates exhibit a condensation transition, where a positive fraction of all particles condenses on a single lattice site when the total density exceeds a critical value.

New Constructions of Zero-Correlation Zone Sequences [PDF]

open access: yesIEEE Transactions on Information Theory, 2013
In this paper, we propose three classes of systematic approaches for constructing zero correlation zone (ZCZ) sequence families. In most cases, these approaches are capable of generating sequence families that achieve the upper bounds on the family size ($K$) and the ZCZ width ($T$) for a given sequence period ($N$).

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
