MLPerf Inference Benchmark
Machine-learning (ML) hardware and software system demand is burgeoning.
Driven by ML applications, the number of different ML inference systems has
exploded. Over 100 organizations are building ML inference chips, and the
systems that incorporate existing models span at least three orders of
magnitude in power consumption and five orders of magnitude in performance;
they range from embedded devices to data-center solutions. Fueling the hardware
are a dozen or more software frameworks and libraries. The myriad combinations
of ML hardware and ML software make assessing ML-system performance in an
architecture-neutral, representative, and reproducible manner challenging.
There is a clear need for industry-wide standard ML benchmarking and evaluation
criteria. MLPerf Inference answers that call. In this paper, we present our
benchmarking method for evaluating ML inference systems. Driven by more than 30
organizations as well as more than 200 ML engineers and practitioners, MLPerf
prescribes a set of rules and best practices to ensure comparability across
systems with wildly differing architectures. The first call for submissions
garnered more than 600 reproducible inference-performance measurements from 14
organizations, representing over 30 systems that showcase a wide range of
capabilities. The submissions attest to the benchmark's flexibility and
adaptability.Comment: ISCA 202

Hadron Fluence Measurements with LiF-TLD Sensors at the Proton Synchrotron Accelerator at CERN
In view of the implementation of beam-monitoring sensors for CERN's Large
Hadron Collider (LHC), and also in order to validate Thermoluminescence
Detectors as a versatile tool to measure ionizing radiation doses in mixed
fields at hadron colliders such as the LHC, chemical vapor deposition diamond
sensors have been evaluated and calibrated at CERN's Proton Synchrotron
accelerator. Special attention was paid to understanding whether
lithiumfluoride thermoluminescence detectors are suitable as measuring devices
in these radiation fields
Project management and presentation of information in financial statements - company performance measurement or project performance measurement
The aim of the article is to draw the attention to the problems related to the presentation of the operational result in case of companies realizing projects contained in a financial report. The article is of discursive nature since the issues that it deals with usually depend on what given solution is selected by a unit in question. Moreover, some of the areas are subject to detailed regulations of the balance law (both domestically - the Act on Accounting and PL GAAP No. 3, and internationally - IAS/IFRS). However, their application may lead to ‘blurring’ a realistic and true picture of the capital and financial situation of a company realizing long-term projects.Celem artykułu jest wskazanie dylematów związanych z prezentacją w sprawozdaniu finansowym wyniku działalności firm realizujących projekty długoterminowe. Artykuł ma charakter dyskusyjny, gdyż poruszane w nim kwestie pozostają zazwyczaj w gestii wyboru określonego rozwiązania przez jednostkę. Ponadto niektóre z obszarów podlegają szczegółowym regulacjom prawa bilansowego (zarówno w wymiarze krajowym - Ustawa o rachunkowości i KSR 3, jak i międzynarodowym - MSR/MSSF), jednak ich stosowanie może powodować "zamazanie" wiernego i rzetelnego obrazu sytuacji majątkowej i finansowej przedsiębiorstwa realizującego projekty długoterminowe
A weak lensing comparability study of galaxy mergers that host AGNs
We compared the total mass density profiles of three different types of
galaxies using weak gravitational lensing: (i) 29 galaxies that host quasars at
z~0.32 that are in a post-starburst (PSQ) phase with high star formation
indicating recent merger activity, (ii) 22 large elliptical galaxies from the
SLACS sample that do not host a quasar at z~0.23, and (iii) 17 galaxies that
host moderately luminous quasars at z~0.36 powered by disk instabilities, but
with no intense star formation. On an initial test we found no evidence for a
connection between the merger state of a galaxy and the profile of the halo,
with the PSQ profile comparable to that of the other two samples and consistent
with the Leauthaud et al. (2014) study of moderately luminous quasars in
COSMOS. Given the compatibility of the two quasar samples, we combined these
and found no evidence for any connection between black hole activity and the
dark matter halo. All three mass profiles remained compatible with
isothermality given the present data.Comment: 6 pages, 3 figures, 1 table, ACCEPTED MNRA
BOOST -- A Satellite Mission to Test Lorentz Invariance Using High-Performance Optical Frequency References
BOOST (BOOst Symmetry Test) is a proposed satellite mission to search for
violations of Lorentz invariance by comparing two optical frequency references.
One is based on a long-term stable optical resonator and the other on a
hyperfine transition in molecular iodine. This mission will allow to determine
several parameters of the standard model extension in the electron sector up to
two orders of magnitude better than with the current best experiments. Here, we
will give an overview of the mission, the science case and the payload.Comment: 11 pages, 2 figures, accepted for publication in Phys. Rev.
Peri-implant diseases and metabolic syndrome components: a systematic review
OBJECTIVE:
Metabolic syndrome (MetS) is defined as a spectrum of conditions associated with an increased risk of developing CVD and type 2 diabetes. MetS include: hyperglycemia, hypertension, visceral obesity, dyslipidemia with elevated values of triglycerides (TG) and low levels of HDL. The aim of this review is to provide current knowledge of the relationship between MetS, its components and peri-implant diseases.
MATERIALS AND METHODS:
An electronic literature search was conducted in the English language in several databases. The Newcastle-Ottawa Scale was used for quality assessment of cohort and cross-sectional studies; while systematic reviews were evaluated through AMSTAR; results were reported according to the PRISMA Statement.
RESULTS:
A total of 272 records were identified through database searching, six studies were included for qualitative analysis. No study directly related to MetS was found, there was inconsistent and controversial evidence regarding association with cardiovascular disease. A higher risk of peri-implantitis was detected in people with hyperglycemia.
CONCLUSIONS:
Future research should be orientated in assessing the risk of peri-implant diseases, evaluating patient's therapeutic response, analyzing directionality of the relationship between MetS, its components and biologic implant complications.
Few studies have investigated the possible relationship between systemic conditions and peri-implant diseases. The aim of this review is to present, in a systematic manner, current evidence and knowledge regarding possible association between cardiovascular disease and implant biologic complications. Out of the one-hundred-eighty-nine studies screened, just five studies were selected for qualitative analysis: three cohort studies (one prospective and two retrospectives) and two cross-sectional studies. According to their results, there is inconsistent and controversial evidence regarding association of cardiovascular disease and implant biologic complications. Future research should be orientated in conducting longitudinal studies, evaluating patients affected by cardiovascular disease rehabilitated with dental implants
