Hardware development and control of a motorized rollator as an extension for exoskeletons
Authors: Bergmann Lukas , Hansmann Lea , Leonhardt Steffen , Ngo Chuong 
Published: November 2022

Abstract
For many elderly, wheeled rollators play an essential role in everyday life’s mobility. In addition, exoskeletons are increasingly used in daily mobility as well as in rehabilitation therapy. We present a motorized rollator to combine the advantages of both support devices. Based on the developed hardware, we design two model-based control concepts. The first relies on distance measurement with ultrasonic sensors, which enables contactless navigation of the rollator, to allow balance training with the exoskeleton. The second control concept enables the balancing of the rollator on its rear wheels as a first step to overcome stairs. Through experiments on the real system, we demonstrate and discuss the functionality and reliability of both control concepts.
Some remarks onh-anticipation in Ancient Greek
Authors: Batisti Roberto 
Published: November 2022

AbstractThis paper investigates the phonological tendency of Ancient Greek to anticipate word-internal aspiration to a word-initial segment (vowel, voiceless stop, or /w/). Special attention is paid to the relationship of this tendency with hiatus resolution. A close look at the philological data shows that several processes ofh-anticipation should be distinguished: in particular, various kinds of perceptually-driven leftward migration of aspiration (sporadically lexicalized) must be kept apart from a later synchronic rule that movedhto the new onset when two syllabic nuclei coalesced. The hypothesis that the latter phenomenon could accompany not only vowel coalescence but other types of hiatus resolution as well, including elision and glide-formation, may provide explanation for some hitherto obscure cases. The results of this study also have implications for the theoretical discussion of sporadicity in sound change, as they could provide further evidence for the controversial category of phonetically-conditioned sound change with probabilistic conditioning.
Industry goes metaverse – the fusion of real and virtual industrial worlds exemplified by the wastewater industry
Authors: Cerniauskas Tomas , Werth Dirk 
Published: November 2022

Abstract
Meeting friends to go shopping, visit a concert or do some sports together – all this and more is now “virtually” possible in the Metaverse. Currently, the creative industries have made the most of the potential of virtual worlds. But the metaverse has no limits. The newly created dynamics raise the question of the extent to which the manufacturing industry can benefit from the potential of these virtual worlds. So far, augmented reality (AR) has been recognized as being useful to the manufacturing industry. The combination of virtual reality (VR) and augmented reality (AR) now unleashes new opportunities for industrial companies. For example, by making a virtual inspection of unmanned facilities possible. A project which has been put into practice by the Entsorgungsverband Saar (EVS) in cooperation with the August-Wilhelm Scheer Institute.

Abstract
The normalizer problem of integral group rings has been studied extensively in recent years due to its connection with the longstanding isomorphism problem of integral group rings. Class-preserving Coleman automorphisms of finite groups occur naturally in the study of the normalizer problem. Let

be a finite group with a nilpotent subgroup

N

G\hspace{-0.0em}\text{/}\hspace{-0.0em}N

acts faithfully on the center of each Sylow subgroup of

N

N

. Then it is proved that every class-preserving Coleman automorphism of

G

G

is an inner automorphism. In addition, if

G

G

is the product of a cyclic normal subgroup and an abelian subgroup, then it is also proved that every class-preserving Coleman automorphism of

G

G

is an inner automorphism. Other similar results are also obtained in this article. As direct consequence, the normalizer problem has a positive answer for such groups.
When teaching works and time helps: Noun modification in L2 English school children

Published: November 2022

AbstractThe study focuses on the interaction between length of exposure and instruction in the L2 English acquisition process of L1 Spanish school children. Two target structures involving noun premodification are targeted: noun–noun (NN) compounds and adjective–noun (AN) strings. Four groups of participants have been studied for 3 years: a group that has been exposed to a specifically designed teaching program targeting NN compounds and a group that has received the regular English instruction program which does not address this structure as part of the curriculum. Two age subgroups appear in each case. The longitudinal judgment data elicited show that performance improves in the cooperation between length of exposure and the exposure to the NN instruction program. Furthermore, it is this last issue that actually takes the lead in that the NN instruction program directly impacts on not only NN compounds but also AN strings. This points to instruction being determinant in the L2 learning process; that is, a consciously and carefully directed instruction is proven to be more effective than length of exposure itself. This study on longitudinal experimental data contributes to shed light on the factors involved in instructed L2 acquisition.
Fast Synaptically Activated Calcium and Sodium Kinetics in Hippocampal Pyramidal Neuron Dendritic Spines
Authors: Miyazaki Kenichi , Ross William N. 
Published: November 2022

AbstractAn accurate assessment of the time course, components, and magnitude of postsynaptic currents is important for a quantitative understanding of synaptic integration and signaling in dendritic spines. These parameters have been studied in some detail in previous experiments, primarily using two-photon imaging of [Ca2+]ichanges and two-photon uncaging of glutamate. However, even with these revolutionary techniques, there are some missing pieces in our current understanding, particularly related to the time courses of synaptically evoked [Ca2+]iand [Na+]ichanges. In new experiments, we used low-affinity, linear Na+and Ca2+indicators, laser fluorescence stimulation, and a sensitive camera-based detection system, combined with electrical stimulation and two-photon glutamate uncaging, to extend measurements of these spine parameters. We found that (1) almost all synaptically activated Na+currents in CA1 hippocampal pyramidal neuron spines in slices from mice of either sex are through AMPA receptors with little Na+entry through voltage-gated sodium channels (VGSCs) or NMDA receptor channels; (2) a spectrum of sodium transient decay times was observed, suggesting a spectrum of spine neck resistances, even on the same dendrite; (3) synaptically activated [Ca2+]ichanges are very fast and are almost entirely because of Ca2+entry through NMDA receptors at the time when the Mg2+block is relieved by the fast AMPA-mediated EPSP; (4) the [Ca2+]ichanges evoked by uncaging glutamate are slower than the changes evoked by synaptic release, suggesting that the relative contribution of Ca2+entering through NMDA receptors at rest following uncaging is higher than following electrical stimulation.
A Redundant Cortical Code for Speech Envelope
Authors: Penikis Kristina B. , Sanes Dan H. 
Published: November 2022

Animal communication sounds exhibit complex temporal structure because of the amplitude fluctuations that comprise the sound envelope. In human speech, envelope modulations drive synchronized activity in auditory cortex (AC), which correlates strongly with comprehension (Giraud and Poeppel, 2012; Peelle and Davis, 2012; Haegens and Zion Golumbic, 2018). Studies of envelope coding in single neurons, performed in nonhuman animals, have focused on periodic amplitude modulation (AM) stimuli and use response metrics that are not easy to juxtapose with data from humans. In this study, we sought to bridge these fields. Specifically, we looked directly at the temporal relationship between stimulus envelope and spiking, and we assessed whether the apparent diversity across neurons' AM responses contributes to the population representation of speech-like sound envelopes. We gathered responses from single neurons to vocoded speech stimuli and compared them to sinusoidal AM responses in auditory cortex (AC) of alert, freely moving Mongolian gerbils of both sexes. While AC neurons displayed heterogeneous tuning to AM rate, their temporal dynamics were stereotyped. Preferred response phases accumulated near the onsets of sinusoidal AM periods for slower rates (<8 Hz), and an over-representation of amplitude edges was apparent in population responses to both sinusoidal AM and vocoded speech envelopes. Crucially, this encoding bias imparted a decoding benefit: a classifier could discriminate vocoded speech stimuli using summed population activity, while higher frequency modulations required a more sophisticated decoder that tracked spiking responses from individual cells. Together, our results imply that the envelope structure relevant to parsing an acoustic stream could be read-out from a distributed, redundant population code.SIGNIFICANCE STATEMENTAnimal communication sounds have rich temporal structure and are often produced in extended sequences, including the syllabic structure of human speech. Although the auditory cortex (AC) is known to play a crucial role in representing speech syllables, the contribution of individual neurons remains uncertain. Here, we characterized the representations of both simple, amplitude-modulated sounds and complex, speech-like stimuli within a broad population of cortical neurons, and we found an overrepresentation of amplitude edges. Thus, a phasic, redundant code in auditory cortex can provide a mechanistic explanation for segmenting acoustic streams like human speech.

Introduction
Anaplastic thyroid carcinoma (ATC) is the most aggressive form of thyroid cancer with a bleak prognosis. Favorable outcomes are rare but help decipher molecular pathophysiology, investigate prognosis factors, and discover new therapeutic targets.

Case presentation
Two patients were diagnosed with locally advanced nonresectable ATC, one with metastatic extension. Each patient received chemotherapy and radiotherapy, allowing thyroid surgical resection. In both cases, the pathological examination was consistent with complete response with no viable tumor cells. After follow-ups of 48 and 70 months, both patients remain disease-free. Molecular explorations on thyroid biopsies revealed microsatellite instability (MSI) and alterations on mismatch repair–gene complex, also PTEN and ATM variants in both cases. Both also presented with non-classical immune infiltrate composed of equal parts T CD4+ lymphocytes and macrophages.

Conclusion
We report two cases of patients cured from advanced ATC and for the first time provide genetic and immunological explorations in this setting. It seems with these two cases that MSI-ATCs may indicate a better prognosis. Our study hypothesizes different responsible mechanisms including increased sensitivity to chemoradiotherapy and/or immune tumor infiltrate modulation.

Authors: Hamner Megan , Nedved Amanda , Austin Holly , Wyly Donna , Burns Alaina , Berg Kathleen , Lee Brian , El Feghaly Rana E. 
Published: November 2022

Background and Objectives
National guidelines recommend a 5- to 7-day course of antibiotics for most skin and soft-tissue infections (SSTIs). Our aim was to increase the percentage of pediatric patients receiving 5 to 7 days of oral antibiotics for SSTIs in our pediatric urgent care clinics (UCCs) from 60% to 75% by December 31, 2021.

Methods
We performed cause-and-effect analysis and surveyed UCC providers to uncover reasons for hesitation with short antibiotic courses for SSTIs. Plan- Do-Study-Act (PDSA) cycle 1 provided an update on current guidelines for UCC providers and addressed providers’ concerns. PDSA cycle 2 modified the electronic health record to display antimicrobial prescription sentences from shortest to longest duration. PDSA cycle 3 provided project outcome and balancing measure updates to UCC providers at regular intervals. We created a monthly report of patients 90 days and older in UCCs with a final diagnosis of SSTIs. We used a Shewhart control chart to identify special cause variations.

Results
After completing our PDSA cycles, we found that the percentage of children receiving 5 to 7 days of oral antibiotics for SSTIs exceeded 85%. The improvement was sustained over multiple months. There was no increase in the proportion of patients returning to the UCCs with an SSTI diagnosis within 14 days.

Conclusions
By addressing primary drivers uncovered through quality improvement methodology, we shortened the antibiotic course for children seen in our UCCs with SSTIs. Outpatient antimicrobial stewardship programs may apply similar methods to other diagnoses to further improve duration of antibiotic prescriptions.

Authors: Chavarría-Zamora Sianny , WingChing-Jones Rodolfo 
Published: November 2022

Los cuestionamientos de los consumidores en torno al bienestar animal han impulsado que los productores de huevo incursionen en sistemas alternativos. El objetivo de esta revisión fue describir las prácticas de alimentación y el bienestar animal de gallinas ponedoras en sistemas con acceso a pastoreo, así como el manejo forrajero y los costos de producción. Se consultaron 87 artículos científicos en bases de datos que se clasificaron en alimentación, comportamiento, características del área de pastoreo, bienestar animal y costos. Un sistema con acceso a pastoreo cuenta con un área externa al galpón cubierta de vegetación en la que las aves pueden estar durante al menos 6 h diarias durante todo el año, si las condiciones climáticas lo permiten. Estos sistemas tienen la necesidad de controlar y manejar las condiciones ambientales, las áreas de pastoreo, el bienestar animal, la sanidad de las aves y los costos de operación. La alimentación alcanza hasta 41% de los gastos, por lo que los productores desean sustituir parte de este con forrajes; con el agravante de que un exceso de forraje causa malnutrición, lo que afecta el bienestar animal y el rendimiento productivo de las mismas. Es fundamental que los empresarios de sistemas de producción de huevo con acceso a pastoreo conozcan el manejo adecuado de las aves y pasturas, con el fin de gestionar el sistema para garantizar la buena nutrición, la manifestación de comportamientos propios de la especie y la ausencia de estrés, miedo, dolor y enfermedad.
Emotional Intelligence as Predictor of Self-Actualization
Authors: Pausanos Melinda 
Published: November 2022

One of the factors that influence self-actualization is emotional intelligence. Being in control of one’s emotions and behavior is an important quality for an older adult to attain self-actualization. This correlational study utilized a multi-stage sample of 180 senior citizens in Tagbilaran City, Bohol. A 3-part instrument package was utilized to (1) describe the respondents’ demographic profile and obtain measures for their (2) emotional intelligence using the 30- item Trait Emotional Intelligence Questionnaire-Short Form (TEIQue-SF) and (3) self-actualization using a 16-item questionnaire developed by Boyum (2004). The study made use of descriptive-correlational design to test the hypothesis that the level of self-actualization of older adults is influenced by their level of emotional intelligence. Data analyses revealed that the majority of the older adults in the sample have high levels of emotional intelligence and self-actualization. A Somer further indicated that emotional intelligence is associated with self-actualization (p=.004). This signifies that older adults who are emotionally intelligent have a higher probability to be self-actualized. Based on the study findings, respecting the emotions of older adults and being treated as individuals with dignity is highly recommended.
Child Abuse and Its Manifestation

Published: November 2022

Child abuse is damaging to a person’s psyche. Children experiencing trauma may respond to it differently. Thus, symptoms vary from physical, mental, emotional, social, behavioral, and psychological reactions. This study intends to ascertain child abuse and its manifestation among the children of the Arms of Love Children’s Home, Cortes, Bohol, Philippines. It utilized a quantitative research design with the aid of a self-constructed questionnaire to gather the perceived symptoms of trauma among the sexually abused, physically abused, neglected, abandoned and surrendered children regarding their physical, mental, emotional, and interpersonal conditions, and the degree of variance among these symptoms. Results revealed that symptoms of trauma were differently manifested by the abused children in the form of physical, mental, emotional, and interpersonal conditions. On the physical conditions, the headache was most evident. Emotional responses to trauma were in the form of an eating problem, guilt feelings, confusion, and hypervigilance. Moreover, this study highlighted sexual and physical abuse as higher degree types of child abuse. However, other forms – neglected, surrendered, abandoned were not taken for granted for these are also detrimental to children’s life.

En México se carece de maíces eloteros seleccionados a partir de maíces criollos, por lo que se requieren estrategias de selección eficientes para mejorar los maíces nativos con características especiales. El objetivo del presente trabajo fue evaluar 16 poblaciones de maíz denominadas RC1F2 seleccionadas para calidad de elote a partir de un compuesto de maíz de la Raza Jala (C1SMJ). La siembra se hizo en el año 2013 en condiciones de secano, en cuatro localidades del estado de Nayarit, bajo un diseño en bloques completos al azar con tres repeticiones. La parcela útil fue de cuatro surcos de 5 m de largo y una distancia entre ellos de 0.80 m. Se midieron variables agronómicas y de calidad de elote. Las poblaciones mejoradas RC1F2 fueron tardías y de porte alto comparado con el híbrido elotero A-7573. En longitud de elote, el 25 % superó al A7573, mientras que en sólidos solubles un 69 % lo igualaron. En rendimiento de elote el 58 % de las poblaciones mejoradas superaron al A-7573 en promedio con 2.156 t ha-1, estos resultados evidencian la contribución genética de la variedad Jala (C1SMJ) y la efectividad del esquema de selección utilizado para el mejoramiento de estas características.Palabras clave: zea mays, retrocruzas, grados Brix y rendimiento de elote.

AbstractSalt crystallization is a major cause of damage in porous building materials. Accelerated salt weathering tests carried out in the laboratory are among the most common methods to assess the durability of material to salt decay. However, existing standards and recommendations for salt weathering tests have limitations in terms of effectiveness and/or reliability. In the framework of the RILEM Technical Committee 271-ASC, a procedure has been developed which proposes a new approach to salt crystallization tests. It starts from the consideration that salt damage can be seen as a process developing in two phases: accumulation of the salt in the material and propagation of the decay. In the first phase, salts are introduced in the material and accumulate close to the evaporation surface, while in the second phase damage propagates because of repeated dissolution and crystallization cycles, induced by re-wetting with liquid water and by relative humidity changes. In this paper, the procedure is described and the results of a first round robin validation of the test, carried out on 7 materials and involving 10 laboratories, are presented. The results show that the procedure is effective to cause decay within the time period of the test (about 3 months) and that the decay increases with subsequent cycles. The decay observed differs in type and severity depending on the salt type and concentration and on the type of substrate. The decay types detected in the laboratories are generally representative of those observed in the field for the selected substrates. The differences in durability between the various substrates, as assessed at the end of the test, are in line with the durability expected based on field observation. The reproducibility of the results in terms of decay type is good; some differences have been observed in terms of material loss. These are more significant in the case of NaCl contaminated specimens. Based on the results, proposals for fine-tuning of the procedure are given.
