Using Dance/Movement Therapy to Improve Mental Health of Modern Chinese People
This article introduces dance/movement therapy as a unique psychotherapeutic modality in treating Chinese clients facing depression, isolation, and other mental health issues in the 21st century. The article shows how dance/movement therapy can help Chinese clients reduce psychological difficulties produced by the conflict of needing to individuate in a modern society but not having enough social and cultural support for this individuation. It also discusses how Kestenberg Movement Profile and its developmental movement concepts can support Chinese clients to reintegrate developmental rhythms that help with individuation. Lastly, the article gives examples of how group therapy can help Chinese clients overcome the barrier of expressing themselves authentically in front of others
The order mesonic chiral Lagrangian
We derive the chiral Lagrangian at next-to-next-to-next-to-leading order
(NNNLO) for a general number of light quark flavours as well as for
. We enumerate the contact terms separately. We also discuss the cases
where some of the external fields are not included. An example of a choice of
Lagrangian is given in the supplementary material.Comment: 23 pages, The file basis.pdf contains the full basis. Minor misprints

Active Tactile Sensing for Texture Perception in Robotic Systems
This thesis presents a comprehensive study of tactile sensing, particularly on the prob- lem of active texture perception. It includes a brief introduction to tactile sensing technology and the neural basis for tactile perception. It follows the literature review of textural percep- tion with tactile sensing. I propose a decoding and perception pipeline to tackle fine-texture classification/identification problems via active touching. Experiments are conducted using a 7DOF robotic arm with a finger-shaped tactile sensor mounted on the end-effector to per- form sliding/rubbing movements on multiple fabrics. Low-dimensional frequency features are extracted from the raw signals to form a perceptive feature space, where tactile signals are mapped and segregated into fabric classes. Fabric classes can be parameterized and sim- plified in the feature space using elliptical equations. Results from experiments of varied control parameters are compared and visualized to show that different exploratory move- ments have an apparent impact on the perceived tactile information. It implies the possibil- ity of optimising the robotic movements to improve the textural classification/identification performance
Scaling Up Dataset Distillation to ImageNet-1K with Constant Memory
Dataset distillation methods aim to compress a large dataset into a small set
of synthetic samples, such that when being trained on, competitive performances
can be achieved compared to regular training on the entire dataset. Among
recently proposed methods, Matching Training Trajectories (MTT) achieves
state-of-the-art performance on CIFAR-10/100, while having difficulty scaling
to ImageNet-1k dataset due to the large memory requirement when performing
unrolled gradient computation through back-propagation. Surprisingly, we show
that there exists a procedure to exactly calculate the gradient of the
trajectory matching loss with constant GPU memory requirement (irrelevant to
the number of unrolled steps). With this finding, the proposed memory-efficient
trajectory matching method can easily scale to ImageNet-1K with 6x memory
reduction while introducing only around 2% runtime overhead than original MTT.
Further, we find that assigning soft labels for synthetic images is crucial for
the performance when scaling to larger number of categories (e.g., 1,000) and
propose a novel soft label version of trajectory matching that facilities
better aligning of model training trajectories on large datasets. The proposed
algorithm not only surpasses previous SOTA on ImageNet-1K under extremely low
IPCs (Images Per Class), but also for the first time enables us to scale up to
50 IPCs on ImageNet-1K. Our method (TESLA) achieves 27.9% testing accuracy, a
remarkable +18.2% margin over prior arts.Comment: ICLR 2023 submission link: https://openreview.net/forum?id=dN70O8pmW
Pair Production of Doubly-Charged Scalars: Neutrino Mass Constraints and Signals at the LHC
We study the pair production of doubly charged Higgs bosons at the Large
Hadron Collider (LHC), assuming the doubly charged Higgs to be part of an
SU(2)_L triplet which generates Majorana masses for left-handed neutrinos. Such
pair-production has the advantage that it is not constrained by the triplet
vacuum expectation value, which tends to make the single production rate rather
small. We point out that, in addition to the Drell-Yan (DY) production
mechanism, two-photon processes also contribute to H++H++ production at a level
comparable to the QCD corrections to the DY channel. Decays of the doubly
charged Higgs into both the l+l+ and W+W+ modes are studied in detail to
optimize the signal observation over the backgrounds. Doubly charged scalars
should be observable at the LHC with 300 fb^-1 integrated luminosity in the ll
channel upto the mass range of 1 TeV even with a branching fraction of about 60
%, and in the WW channel upto a mass of 700 GeV. Such a doubly charged Higgs,
if it is a member of a triplet generating neutrino masses,cannot be long-lived
on the scale of collider detectors although it might lead to a displaced
secondary vertex during its decay if it is lighter than about 250 GeV.Comment: revtex4, 23 pages, 14 figures, version published in Physical Review
Study of the mixing in the decays
We studied the B meson decays in the pQCD
approach beyond the leading order. With the vertex corrections and the NLO
Wilson coefficients included, the branching ratios of the considered decays are
, and with the mixing angle
, which can agree well with the data or the present
experimental upper limit within errors. So we support the opinion that
is much more favored than . Furthermore,
we also give the predictions for the polarization fractions, direct CP
violations from the different polarization components, the relative phase
angles for the considered decays with the mixing angle
and , respectively. The direct CP violations of the two charged
decays are very small ,
because there is no weak phase until up to with the
Wolfenstein parameter . These results can be tested at the
running LHCb and forthcoming Super-B experiments.Comment: 14 pages,3 figures,to appear in EPJ
