title: Online and offline heuristics for inferring hierarchies of repetitions in sequences

authors: Nevill-Manning, Craig G.

subjects: dictionary compression

abstract: Hierarchical dictionary-based compression schemes form a grammar for a text by replacing each repeated string with a production rule. While such schemes usually operate online, making a replacement as soon as repetition is detected, offline operation permits greater freedom in choosing the order of replacement. In this paper, we compare the online method with three offline heuristics for selecting the next substring to replace: longest string first, most common string first, and the string that minimized the size of the grammar locally. Surprisingly, two of the offline techniques, like the online method, run in time linear in the size of the input. We evaluate each technique on artificial and natural sequences. In general, the locally-most-compressive heuristic performs best, followed by most frequent, the online technique, and, lagging by some distance, the longest-first technique.

title: The effect of tissue flossing on ankle range of motion, jump and sprint performance in elite rugby ‎union athletes

authors: Mills, Blair Stephen

abstract: Context:
Given the relatively novel technique of tissue flossing is currently lacking in the research literature despite some positive findings in preliminary studies, the modality clearly requires further research. Current evidence suggests that band flossing results in performance improvements and may also be an effective method in injury prevention.

Objective:
Previous research has shown that tissue flossing may result in increased ankle ROM, jump and sprinting performance in recreational athletes. The present study aims to extend on this research, within an elite athlete sample.

Design:
counter-balanced, crossover design with experimental and control trials, separated by one week.

Setting:
University laboratory.

Participants:
14 professional male rugby union athletes (mean ± SD: age; 23.9 ± 2.7).

Intervention:
Application of a floss band to both ankles (FLOSS) for two minutes or without flossing of the ankle joints (CON) on two separate occasions.

Main Outcome Measures:
A weight-bearing lunge test (WBLT), a countermovement (CMJ) jump test and a 20m sprint (SPRINT) test pre and at 5 and 30 minutes post application of the floss band or control.

Results:
There were no statistically significant interactions between treatment (FLOSS/CON) and time for any of the measured variables (p > 0.05). Effect size analysis revealed small benefits for FLOSS in comparison to CON for CMJ performance 5 mins post (d = 0.28) and for 10m (d = -0.45) and 15m (d = -0.24) sprint time 30 mins post.

Conclusion:
Findings from the current study suggest minimal benefits of tissue flossing when applied to the ankle joint in elite athletes for up to 30 minutes following their application.

title: He whakaemi kōrero mō Ngā Ruahine

Ko te ūpoko tuatahi, ko ngā pakiaka, arā te tīmatatanga o Ngā Ruahine. I konei ka tirohia ngā kōrero mō ngā waka tawhito mete whakapapa hoki o ngā tūpuna tāngatawhenua o Ngā Ruahine. Whai muri i tēnā, he wāhanga e pā ana ki te haeretanga mai o Aotea waka, ā, ka tirohia hoki tētehi kōrero tawhito mō te wehenga o ngā iwi o Aotea.
Mai i ngā pakiaka ka piki ake ki te tinana o te rākau. Koinei te wāhanga e pā ana ki ngā korero whenua o Ngā Ruahine. Kei te ūpoko tuarua nei, ka āta tirohia ngā kōrero mō ngā tongi o te rohe o Ngā Ruahine, me ngā take kōrero e whakawhanaunga ana i te tangata ki te whenua. Kei te ūpoko tuarua anō hoki ētehi whakaaturanga whenua mō te rohe o Ngā Ruahine, hei āwhina i te kaipānui.  
Mai i te tinana, ka aro atu ki ngā peka o te rākau i raro i te ūpoko tuatoru. Koinei te wāhanga nui o tēnei tuhingaroa, nā te tokomaha o ngā toronga o ngā peka nei.

Ko tēnei tuhingaroa, he whakaemi kōrero mai i ngā kaumātua o Ngā Ruahine, ā, he mea tango mai hoki ētehi kōrero i ngā pukapuka, ko ēnei kōrero kua whakatakotoria i roto i tēnei tuhingaroa hei whakawhāriki iho ki te aroaro o te tini.
