Patterns of grammaticalization in African languages
The approach outlined in the present paper is based on observations made with African languages. Although the 1000-odd African languages display a remarkable extent of structural variation, there are certain structures that do not seem to occur in Africa. Thus, to our knowledge, an African language having anything that could be called an ergative case or a numeral classifier system has not been discovered so far. It may turn out that our approach can, in a modified form, be made applicable to languages outside Africa. This , however, is a possibility that has not been considered here. The present approach is based essentially on diachronic findings in that it uses observations on language evolution in order to account for structural differences between languages. Thus, it has double potential: apart from describing and explaining typological diversity it can also be material to reconstructing language history
ACCL+: an FPGA-Based Collective Engine for Distributed Applications
FPGAs are increasingly prevalent in cloud deployments, serving as Smart NICs
or network-attached accelerators. Despite their potential, developing
distributed FPGA-accelerated applications remains cumbersome due to the lack of
appropriate infrastructure and communication abstractions. To facilitate the
development of distributed applications with FPGAs, in this paper we propose
ACCL+, an open-source versatile FPGA-based collective communication library.
Portable across different platforms and supporting UDP, TCP, as well as RDMA,
ACCL+ empowers FPGA applications to initiate direct FPGA-to-FPGA collective
communication. Additionally, it can serve as a collective offload engine for
CPU applications, freeing the CPU from networking tasks. It is user-extensible,
allowing new collectives to be implemented and deployed without having to
re-synthesize the FPGA circuit. We evaluated ACCL+ on an FPGA cluster with 100
Gb/s networking, comparing its performance against software MPI over RDMA. The
results demonstrate ACCL+'s significant advantages for FPGA-based distributed
applications and highly competitive performance for CPU applications. We
showcase ACCL+'s dual role with two use cases: seamlessly integrating as a
collective offload engine to distribute CPU-based vector-matrix multiplication,
and serving as a crucial and efficient component in designing fully FPGA-based
distributed deep-learning recommendation inference

Contributions of mean and shape of blood pressure distribution to worldwide trends and variations in raised blood pressure : a pooled analysis of 1018 population-based measurement studies with 88.6 million participants
Background: Change in the prevalence of raised blood pressure could be due to both shifts in the entire distribution of blood pressure (representing the combined effects of public health interventions and secular trends) and changes in its high-blood-pressure tail (representing successful clinical interventions to control blood pressure in the hypertensive population). Our aim was to quantify the contributions of these two phenomena to the worldwide trends in the prevalence of raised blood pressure. Methods: We pooled 1018 population-based studies with blood pressure measurements on 88.6 million participants from 1985 to 2016. We first calculated mean systolic blood pressure (SBP), mean diastolic blood pressure (DBP) and prevalence of raised blood pressure by sex and 10-year age group from 20–29 years to 70–79 years in each study, taking into account complex survey design and survey sample weights, where relevant. We used a linear mixed effect model to quantify the association between (probittransformed) prevalence of raised blood pressure and age-group- and sex-specific mean blood pressure. We calculated the contributions of change in mean SBP and DBP, and of change in the prevalence-mean association, to the change in prevalence of raised blood pressure. Results: In 2005–16, at the same level of population mean SBP and DBP, men and women in South Asia and in Central Asia, the Middle East and North Africa would have the highest prevalence of raised blood pressure, and men and women in the highincome Asia Pacific and high-income Western regions would have the lowest. In most region-sex-age groups where the prevalence of raised blood pressure declined, one half or more of the decline was due to the decline in mean blood pressure. Where prevalence of raised blood pressure has increased, the change was entirely driven by increasing mean blood pressure, offset partly by the change in the prevalence-mean association. Conclusions: Change in mean blood pressure is the main driver of the worldwide change in the prevalence of raised blood pressure, but change in the high-blood-pressure tail of the distribution has also contributed to the change in prevalence, especially in older age groups
