Contextually Performing Query Processing On-device or On a Remote Server

When a user issues a query, e.g., a spoken query to a user device such as a smartphone, smart speaker, in-car device, etc., the query may be processed locally on-device and additionally, remotely on a server (if permitted by the user). The determination of whether a query is processed locally or on a remote device is typically based on whether the device has a network connection. Local processing of queries can consume device resources. When the device is simultaneously in use for other critical tasks, such resource demand can have a negative impact on such tasks. This disclosure describes the use of a trained machine learning model that takes into account user-permitted contextual factors to determine whether query processing is to be performed on-device or on a remote server

Do WTO rules preclude industrial policy? Evidence from the global economic crisis

The creation of the World Trade Organization (WTO) in 1995 was a landmark in the development of the liberal international economic order. Yet the global economic crisis of 2008 put the spotlight on the longstanding question whether WTO membership limited the policy choices of governments coping with distress. This Special Issue of Business and Politics uses the crisis as a "stress test” for evaluating the prominent thesis that multilateral trade rules presently impose sharp limits on national industrial policies. The evidence from a wide range of sectoral and national contexts suggests that the WTO's ability to constrain member governments' use of industrial policy is highly exaggerated. As we argue in this introductory essay, and as the studies in this Issue show, assertions of the WTO's strength do not reflect the incomplete and contested nature of its accords and the imperatives of policymaking in an era when many governments simultaneously intervene in national economie

Mega-FTAs and the trade-security nexus : the Trans-Pacific Partnership (TPP) and the Regional Comprehensive Economic Partnership (RCEP)

For more about the East-West Center, see http://www.eastwestcenter.org/Following on the development of sectoral, bilateral, and regional free trade agreements (FTAs), “mega-FTAs” are now proposed that could link economies across regions. The US and China are promoting rival accords: the Trans-Pacific Partnership (TPP), which would encompass 800 million people and almost 40 percent of global GDP, is a centerpiece of the Obama Asia Pacific strategy. The Regional Comprehensive Economic Partnership (RCEP) would account for 30 percent of global GDP, with a population of over three billion people, creating the largest FTA in the world. TPP advocates assert that it will strengthen the US’s strategic role in the region, in part by countering China’s membership in the RCEP. These claims, made in response to growing skepticism in the United States about the value of liberalized trade, over-emphasize the TPPs strategic value. At the same time, projecting the economic impact of the TPP is thorny, given the deal’s scope and the diversity of countries involved

Scheduling and Power Control for Wireless Multicast Systems via Deep Reinforcement Learning

Multicasting in wireless systems is a natural way to exploit the redundancy in user requests in a Content Centric Network. Power control and optimal scheduling can significantly improve the wireless multicast network's performance under fading. However, the model based approaches for power control and scheduling studied earlier are not scalable to large state space or changing system dynamics. In this paper, we use deep reinforcement learning where we use function approximation of the Q-function via a deep neural network to obtain a power control policy that matches the optimal policy for a small network. We show that power control policy can be learnt for reasonably large systems via this approach. Further we use multi-timescale stochastic optimization to maintain the average power constraint. We demonstrate that a slight modification of the learning algorithm allows tracking of time varying system statistics. Finally, we extend the multi-timescale approach to simultaneously learn the optimal queueing strategy along with power control. We demonstrate scalability, tracking and cross layer optimization capabilities of our algorithms via simulations. The proposed multi-timescale approach can be used in general large state space dynamical systems with multiple objectives and constraints, and may be of independent interest.Comment: arXiv admin note: substantial text overlap with arXiv:1910.0530

Prevalence of Dental Caries and Dental Fluorosis among 7-12-Year-Old School Children in an Indian Subpopulation: A Cross-Sectional Study

Objective: To assess the prevalence of dental caries and fluorosis among 7-12-year-old school children in Muradnagar, India. An additional objective was to determine the relationship between dental caries and fluorosis in the studied population. Material and Methods: A total of 1500 school children aged between 7 to 12 years, and both genders were randomly selected for the present study. The selected participants were divided into three groups based upon age, viz 7-8 year (group I), 9-10 year (group II) and 11-12 year (group III). Sterile mouth mirrors and explorers were used for the detection of caries. The water samples were collected to assess the fluoride concentration. The data collected were tabulated and statistically analysed using Chi-square, ANOVA, Spearman’s correlation and t-test wherever applicable. Results: Out of 1500 participants, 54.1% were females and 45.9% were males. The prevalence of dental caries and fluorosis was 89.3% and 93.7%, respectively. The prevalence of caries increased with age (p<0.05) and females showed a higher prevalence in both the dentitions. Most dental fluorosis was ‘very mild’ (40.1%). Prevalence of dental fluorosis increased with age and males showed more fluorosis than females. A negative relationship was found between dental caries and fluorosis (p<0.05). Conclusion: Dental caries and fluorosis are the public health problems in Muradnagar; therefore, preventive programs should be organized to increase awareness among the general people

Effect of superphosphate, urea and bioinoculants on Zinnia elegans Jacq.

Current agricultural practices depend heavily on chemical inputs, and their overuse seriously contaminates the soil health. Microbial bioinoculants are emerging as an effective greener replacement for chemical fertilizers. These bioinoculants are beneficial for plant growth and also diminishes pathogenicity. Here, we explored three microbial inoculants along with commonly used fertilizers, i.e., Superphosphate (SP) and Urea (UR) for their effectiveness on Zinnia elegans Jacq., that has considerable demand in the floral market. The experiment was conducted in three parts with recommended doses of fertilizers, low (half) doses, and high (double) doses in combination with Glomus mosseae (GM), Acaulospora laevis (AL) and Pseudomonas fluorescens (PF), as microbial inoculants. The consortium of microbial inoculants (GM+AL+PF) fed with the low dose of SP and UR gave the best results for growth parameters (Shoot and Root Length, Shoot and Root Weight), Floral traits (floral head number and diameter), mycorrhization pattern and for other physiological attributes (shoot phosphorus content, root phosphorus content, acidic phosphatase, alkaline phosphatase). Overall, the study establishes that microbial bioinoculants is a potential fertilizer supplement at the recommended dose supports optimum Z. elegans growth

Lattice Problems Beyond Polynomial Time

We study the complexity of lattice problems in a world where algorithms, reductions, and protocols can run in superpolynomial time, revisiting four foundational results: two worst-case to average-case reductions and two protocols. We also show a novel protocol. 1. We prove that secret-key cryptography exists if $\widetilde{O}(\sqrt{n})$-approximate SVP is hard for $2^{\varepsilon n}$-time algorithms. I.e., we extend to our setting (Micciancio and Regev's improved version of) Ajtai's celebrated polynomial-time worst-case to average-case reduction from $\widetilde{O}(n)$-approximate SVP to SIS. 2. We prove that public-key cryptography exists if $\widetilde{O}(n)$-approximate SVP is hard for $2^{\varepsilon n}$-time algorithms. This extends to our setting Regev's celebrated polynomial-time worst-case to average-case reduction from $\widetilde{O}(n^{1.5})$-approximate SVP to LWE. In fact, Regev's reduction is quantum, but ours is classical, generalizing Peikert's polynomial-time classical reduction from $\widetilde{O}(n^2)$-approximate SVP. 3. We show a $2^{\varepsilon n}$-time coAM protocol for $O(1)$-approximate CVP, generalizing the celebrated polynomial-time protocol for $O(\sqrt{n/\log n})$-CVP due to Goldreich and Goldwasser. These results show complexity-theoretic barriers to extending the recent line of fine-grained hardness results for CVP and SVP to larger approximation factors. (This result also extends to arbitrary norms.) 4. We show a $2^{\varepsilon n}$-time co-non-deterministic protocol for $O(\sqrt{\log n})$-approximate SVP, generalizing the (also celebrated!) polynomial-time protocol for $O(\sqrt{n})$-CVP due to Aharonov and Regev. 5. We give a novel coMA protocol for $O(1)$-approximate CVP with a $2^{\varepsilon n}$-time verifier. All of the results described above are special cases of more general theorems that achieve time-approximation factor tradeoffs

Engineered reversal of drug resistance in cancer cells - metastases suppressor factors as change agents

Building molecular correlates of drug resistance in cancer and exploiting them for therapeutic intervention remains a pressing clinical need. To identify factors that impact drug resistance herein we built a model that couples inherent cell-based response toward drugs with transcriptomes of resistant/sensitive cells. To test this model, we focused on a group of genes called Metastasis Suppressor Genes (MSGs) that influence aggressiveness and metastatic potential of cancers. Interestingly, modeling of 84 000 drug response transcriptome combinations predicted multiple MSGs to be associated with resistance of different cell types and drugs. As a case study, on inducing MSG levels in a drug resistant breast cancer line resistance to anticancer drugs caerulomycin, camptothecin and topotecan decreased by more than 50–60 %, in both culture conditions and also in tumors generated in mice, in contrast to control un-induced cells. To our knowledge, this is the first demonstration of engineered reversal of drug resistance in cancer cells based on a model that exploits inherent cellular response profiles
