WiscSort: External Sorting For Byte-Addressable Storage
We present WiscSort, a new approach to high-performance concurrent sorting
for existing and future byte-addressable storage (BAS) devices. WiscSort
carefully reduces writes, exploits random reads by splitting keys and values
during sorting, and performs interference-aware scheduling with thread pool
sizing to avoid I/O bandwidth degradation. We introduce the BRAID model which
encompasses the unique characteristics of BAS devices. Many state-of-the-art
sorting systems do not comply with the BRAID model and deliver sub-optimal
performance, whereas WiscSort demonstrates the effectiveness of complying with
BRAID. We show that WiscSort is 2-7x faster than competing approaches on a
standard sort benchmark. We evaluate the effectiveness of key-value separation
on different key-value sizes and compare our concurrency optimizations with
various other concurrency models. Finally, we emulate generic BAS devices and
show how our techniques perform well with various combinations of hardware

Dietary supplementation of <i>Aloe vera</i> extract modulates rumen microbes and improves the functional food value of milk by altering phenolic content, antioxidant capacity, and fatty acid profile in lactating goats
Twenty-four cross-breed (Alpine × Beetal) lactating goats (average body weight: 37.5 ± 2.7 kg and milk yield: 1.78 ± 0.31 kg/day) were chosen for the ninety days duration of the experiment and divided into three groups following a completely randomized design. Group I acted as control (T0) and received only a basal diet as per requirement, whereas group II (T1) and group III (T2) received basal diet added with Aloe vera extract at 2% and 4% of dry matter intake (DMI), respectively. Total phenolic compounds (TPC) and milk antioxidant status were higher (p 1 and T2 than T0. Relative abundance of methanogen, protozoa, Butyrivibrio proteoclasticus, and Ruminococcus flavefaciens in the rumen were lower, while Butyrivibrio fibrisolvens population was higher (p 2 and T1 compared to T0. Saturated fatty acids levels in milk were lower, whereas different polyunsaturated fatty acids levels were higher (p 1 and T2 than T0. Nutritional indices of milk increased in both supplemented groups. Overall, it may be concluded that dietary supplementation of Aloe vera extract at 2% and 4% of DMI may enhance the functional characteristics of milk by boosting TPC and antioxidant status, as well as the FA profile and nutritional quality indices of milk fat.</p
