Geopolitics, Ethnic Politics along the Border, and Chinese Foreign Policy Changes toward Myanmar
Ever since Myanmar reoriented its foreign policy as a result of its transition to democratic rule in 2010, it has significantly improved its relations with the West, particularly the United States. Amid heightened geostrategic competition between the U.S. and China, how can we understand the Chinese government’s changing approaches to Myanmar, where China’s strategic and economic interests face unprecedented pressure? This article examines those changes in the context of the Chinese government’s response to three militarized ethnic conflicts along its border with Myanmar before and after Myanmar’s foreign policy reorientation. Drawing evidence from Chinese Ministry of Foreign Affairs statements and Chinese media coverage of the 2009 and 2015 Kokang conflicts and the 2011-2013 Kachin conflict, the article argues that combined geopolitical changes and domestic nationalist signaling explain the variations of China’s foreign policy approaches to Myanmar. The article thus contributes to ongoing interest in China’s foreign policy approaches to Southeast Asia in the wake of geostrategic competition between China and the United States

Forgotten conflicts: producing knowledge and ignorance in security studies
Security studies privileges the study of civil wars in some contexts over others. The field's leading journals mostly publish studies of armed conflicts in Africa, Eastern Europe, and the Middle East. Armed conflicts in Asia receive comparatively little attention, despite their prevalence and protracted nature. Against the background of our own empirical archive—the decades-old but largely ignored civil war in Myanmar—we ask why some conflicts draw more scholarly interest than others and why this uneven attention matters. In doing so, we argue that the empirical selectivity bias in the study of civil war and armed conflict reflects (1) institutional entanglements between the field of security studies and Western foreign policy; and (2) sociological factors that shape the formation of scholarly subjectivities and pertain to methodological challenges. This uneven empirical landscape shapes our conceptual understanding of civil wars. In fact, prominent debates within leading security studies journals surrounding the nature of civil war and armed conflict are inseparable from the empirical contexts in which they emerged. Leveling such an uneven empirical landscape thus generates opportunities for discussing conflict, insecurity, and violence in a different light. In shedding light on this issue, we urge closer attention to questions of place, time, and power in the scholarly production of knowledge and ignorance

External Kin, Economic Disparity, and Minority Ethnic Group Mobilization
What is the relationship between economic grievance and ethnopolitical conflict? Many theories on ethnic conflict posit a relationship between economic inequality and conflict, and many tend to agree that economic inequality between groups is one of the main causes of grievance and thereby political mobilization. This article engages existing literature on horizontal inequalities, but probes the violent consequences of a different type of economic inequality. In particular, we are interested in the type of ethnic group that has extensive external kin relations, and how in such conditions the economic disparity between the ethnic group and its external kin group condition the former’s grievance construction. We argue that, if the ethnic group’s external kin enjoys positive economic advantage over the ethnic group, then the latter is more likely to feel deprived and engage in violent political mobilization toward the current host state
DiffFit: Unlocking Transferability of Large Diffusion Models via Simple Parameter-Efficient Fine-Tuning
Diffusion models have proven to be highly effective in generating
high-quality images. However, adapting large pre-trained diffusion models to
new domains remains an open challenge, which is critical for real-world
applications. This paper proposes DiffFit, a parameter-efficient strategy to
fine-tune large pre-trained diffusion models that enable fast adaptation to new
domains. DiffFit is embarrassingly simple that only fine-tunes the bias term
and newly-added scaling factors in specific layers, yet resulting in
significant training speed-up and reduced model storage costs. Compared with
full fine-tuning, DiffFit achieves 2 training speed-up and only needs
to store approximately 0.12\% of the total model parameters. Intuitive
theoretical analysis has been provided to justify the efficacy of scaling
factors on fast adaptation. On 8 downstream datasets, DiffFit achieves superior
or competitive performances compared to the full fine-tuning while being more
efficient. Remarkably, we show that DiffFit can adapt a pre-trained
low-resolution generative model to a high-resolution one by adding minimal
cost. Among diffusion-based methods, DiffFit sets a new state-of-the-art FID of
3.02 on ImageNet 512512 benchmark by fine-tuning only 25 epochs from a
public pre-trained ImageNet 256256 checkpoint while being 30
more training efficient than the closest competitor.Comment: Tech Repor

British Colonialism and the Criminalization of Homosexuality
What explains the global variation in laws criminalizing homosexual conduct? Recent research has claimed that British colonialism is largely responsible for the criminalization of homosexuality around the world. This article utilizes a newly constructed dataset that includes up-to-date data on 185 countries to assess this claim. We find that British colonies are much more likely to have criminalization of homosexual conduct laws than other colonies or other states in general. This result holds after controlling for other variables that might be expected to influence the likelihood of repressive lesbian, gay, bisexual and transgender (LGBT) rights legislation. However, we also find that the evidence in favour of the claim that British imperialism ‘poisoned’ societies against homosexuality is weak. British colonies do not systematically take longer to decriminalize homosexual conduct than other European colonies
LEGO-Prover: Neural Theorem Proving with Growing Libraries
Despite the success of large language models (LLMs), the task of theorem
proving still remains one of the hardest reasoning tasks that is far from being
fully solved. Prior methods using language models have demonstrated promising
results, but they still struggle to prove even middle school level theorems.
One common limitation of these methods is that they assume a fixed theorem
library during the whole theorem proving process. However, as we all know,
creating new useful theorems or even new theories is not only helpful but
crucial and necessary for advancing mathematics and proving harder and deeper
results. In this work, we present LEGO-Prover, which employs a growing skill
library containing verified lemmas as skills to augment the capability of LLMs
used in theorem proving. By constructing the proof modularly, LEGO-Prover
enables LLMs to utilize existing skills retrieved from the library and to
create new skills during the proving process. These skills are further evolved
(by prompting an LLM) to enrich the library on another scale. Modular and
reusable skills are constantly added to the library to enable tackling
increasingly intricate mathematical problems. Moreover, the learned library
further bridges the gap between human proofs and formal proofs by making it
easier to impute missing steps. LEGO-Prover advances the state-of-the-art pass
rate on miniF2F-valid (48.0% to 57.0%) and miniF2F-test (45.5% to 47.1%).
During the proving process, LEGO-Prover also manages to generate over 20,000
skills (theorems/lemmas) and adds them to the growing library. Our ablation
study indicates that these newly added skills are indeed helpful for proving
theorems, resulting in an improvement from a success rate of 47.1% to 50.4%. We
also release our code and all the generated skills
Co-Targeting Plk1 and DNMT3a in Advanced Prostate Cancer
Because there is no effective treatment for late-stage prostate cancer (PCa) at this moment, identifying novel targets for therapy of advanced PCa is urgently needed. A new network-based systems biology approach, XDeath, is developed to detect crosstalk of signaling pathways associated with PCa progression. This unique integrated network merges gene causal regulation networks and protein-protein interactions to identify novel co-targets for PCa treatment. The results show that polo-like kinase 1 (Plk1) and DNA methyltransferase 3A (DNMT3a)-related signaling pathways are robustly enhanced during PCa progression and together they regulate autophagy as a common death mode. Mechanistically, it is shown that Plk1 phosphorylation of DNMT3a leads to its degradation in mitosis and that DNMT3a represses Plk1 transcription to inhibit autophagy in interphase, suggesting a negative feedback loop between these two proteins. Finally, a combination of the DNMT inhibitor 5-Aza-2\u27-deoxycytidine (5-Aza) with inhibition of Plk1 suppresses PCa synergistically
Ethnic Integration and Development in China
This paper pursues an inquiry into the relationship between ethnicity and development in the largest authoritarian country in the contemporary world, the People’s Republic of China. It engages the theoretical literature on ethnic diversity and development in general, but also pays special attention to political economy logics unique to authoritarian systems. Focusing on the western part of China over a decade since the launch of China’s Western Development Program (xibu da kaifa) in 2000, this paper utilizes the data from two censuses (2000 and 2010) together with nighttime streetlight imagery data to analyze the overall relationship between ethnicity and development provision. It also analyzes changes in such a relationship during this period. The paper finds that ethnic minority concentration negatively correlates with economic development in both the years 2000 and 2010 across the western provinces. It also finds that counties in non-autonomous provinces, which are historically more integrated with the rest of China than autonomous provinces, have a positive and systematic correlation between changes in ethnic minority concentration and changes in development during the 10-year period. The counties in autonomous provinces, on the other hand, show the opposite trend. Using three case studies of Tibet, Inner Mongolia, and Xinjiang, the paper concludes that although there is in general a tendency for ethnic minority concentrated areas to be less developed, ultimately which groups prosper more or less depends upon specific economic development and which political control logics the Chinese state implements
