Measurements of minimum bias events, underlying event and particle production properties in ATLAS
The measurements of the minimum bias events provide valuable information on
the basic properties of the interactions. The results at the new highest
energy of collisions, = 13 TeV, obtained using the ATLAS
detector, are shown. They include distributions of charged particle
pseudorapidity density, transverse momentum and multiplicity. The properties of
the underlying event, determined with respect to a leading high-
particle, are also presented. In both cases the new results are compared with
those from earlier studies of the collisions at = 7 TeV.Comment: Proceedings of the 23rd Low-x Meeting, Sandomierz, Poland, September

Communication competences of managers in the twenty first century
Communication competences of a manager in the 21st century have a
significant effect on the creation of a competitive advantage of an organization.
They compose an immanent part of behaviours of all persons in an organization
responsible for producing the pro-effective culture. They create efficacy, that
is effectiveness and efficiency in the realization of its basic aims targets. They
affect proper functions of all essential structural units of organizations. Their
implementation requires inter alia a heuristic approach to interpersonal
communication processes in an organization. Therefore, they can be guided by
the following principles:
1. principle of communication dualism – awareness of process ephemerality
and multithreading,
2. principle of communication intelligence – adaptiveness of communication,
3. principle of taking into account situational and socio-cultural contexts,
4. principle of individual personality features of partners in the communication
process,
5. principle of skilful usage and reading of verbal expressions and non-verbal
signals,
6. principle of utilization of knowledge and experience adequately to the
situation,
7. principle of high-level ethical behaviours,
8. and principle of self-control
Smart Kitchens for People with Cognitive Impairments: A Qualitative Study of Design Requirements
Individuals with cognitive impairments currently leverage extensive human resources during their transitions from assisted living to independent living. In Western Europe, many government-supported volunteer organizations provide sheltered living facilities; supervised environments in which people with cognitive impairments collaboratively learn daily living skills. In this paper, we describe communal cooking practices in sheltered living facilities and identify opportunities for supporting these with interactive technology to reduce volunteer workload. We conducted two contextual observations of twelve people with cognitive impairments cooking in sheltered living facilities and supplemented this data through interviews with four employees and volunteers who supervise them. Through thematic analysis, we identified four themes to inform design requirements for communal cooking activities: Work organization, community, supervision, and practicalities. Based on these, we present five design implications for assistive systems in kitchens for people with cognitive deficiencies
Formation of the vertebral arches of the cervical, thoracic and lumbar vertebrae in early human foetuses
Fusion of the neural arches was studied in 6 serially sectioned human foetuses
aged 9 and 10 weeks. In foetuses of 9 weeks, the completion of arches was
observed in the cervical, upper thoracic, and middle thoracic regions of the
vertebral column. During the 10th week of development, fusion of neural processes
progresses in the lower thoracic and upper three lumbar vertebrae.

Innervation of the human cervical and thoracic vertebrae at eight postovulatory weeks
The nerves to the cervical and thoracic vertebrae were traced in 10 serially
sectioned human embryos. It was found that the vertebral bodies receive nerve
fibres from the trunks of the spinal nerves, anterior branches and meningeal
branches of the spinal nerves, and from the sympathetic trunks. Slender twigs
from the trunk of the spinal nerve arise close to the spinal ganglion and terminate
in the posterior and lateral surfaces of the vertebrae. Fibres from the anterior
branches of the spinal nerves terminate in the lateral and anterior surfaces
of the vertebrae. Thin rami from the sympathetic trunk reach the anterior surface
of the vertebrae
Early foetal development of the articular disc in the human temporomandibular joint
In foetuses of 9 and 10 weeks the articular disc presents a more cellular structure
with bands of connective tissue fibres. It is connected with the articular
capsule and lateral pterygoid muscle. During weeks 11 and 12 there is an increase
in collagenous fibres and fusiform cells are located mainly close to the
surface of the disc
The length of the humerus in human embryos at developmental stages 18-23
The length of the humerus was measured in 69 staged human embryos at developmental
stages 18-23 (7 and 8 weeks). It was found that the length of the
humerus increases from 2.0 mm at stage 18 to 5.4 mm at stage 23. There were
slight variations at certain of the stages investigated. Asymmetry between limb
lengths was not found during the embryonic period under examination
The Development and Validation of the Technology-Supported Reflection Inventory
Reflection is an often addressed design goal in Human-Computer Interaction
(HCI) research. An increasing number of artefacts for reflection have been
developed in recent years. However, evaluating if and how an interactive
technology helps a user reflect is still complex. This makes it difficult to
compare artefacts (or prototypes) for reflection, impeding future design
efforts. To address this issue, we developed the \emph{Technology-Supported
Reflection Inventory} (TSRI), which is a scale that evaluates how effectively a
system supports reflection. We first created a list of possible scale items
based on past work in defining reflection. The items were then reviewed by
experts. Next, we performed exploratory factor analysis to reduce the scale to
its final length of nine items. Subsequently, we confirmed test-retest validity
of our instrument, as well as its construct validity. The TSRI enables
researchers and practitioners to compare prototypes designed to support
reflection.Comment: CHI Conference on Human Factors in Computing Systems (CHI '21), May

The development of the epidural space in human embryos
The epidural space is seen in embryos at stage 17 (41 days) on the periphery of
the primary meninx. During stage 18 (44 days) the dura mater proper appears
and the epidural space is located between this meninx and the perichondrium
and contains blood vessels. During the last week of the embryonic period (stages
20–23) the epidural space is evident around the circumference of the spinal
cord. On the posterior surface it is found between the dura mater and the mesoderm
of the dorsal body wall
Inertia compensation while scanning screw threads on coordinate-measuring machines
Usage of scanning coordinate-measuring machines for inspection of screw
threads has become a common practice nowadays. Compared to touch trigger
probing, scanning capabilities allow to speed up measuring process while still
maintaining high accuracy. However, in some cases accuracy drasticaly depends
on the scanning speed. In this paper a compensation method is proposed allowing
to reduce the influence of some dynamic effects while scanning screw threads on
coordinate-measuring machines
