Distributed Temperature Control in Laser-Based Manufacturing
Authors: Zheng Chengjian , Wen John T. , Diagne Mamadou 
Published: January 2020

Abstract
Temperature control is essential for regulating material properties in laser-based manufacturing. Motion and power of the scanning laser affect local temperature evolution, which in turn determines the a posteriori microstructure. This paper addresses the problem of adjusting the laser speed and power to achieve the desired values of key process parameters: cooling rate and melt pool size. The dynamics of a scanning laser system is modeled by a one-dimensional (1D) heat conduction equation, with laser power as the heat input and heat dissipation to the ambient. Since the model is 1D, length and size are essentially the same. We pose the problem as a regulation problem in the (moving) laser frame. The first step is to obtain the steady-state temperature distribution and the corresponding input based on the desired cooling rate and melt pool size. The controller adjusts the input around the steady-state feedforward based on the deviation of the measured temperature field from the steady-state distribution. We show that with suitably defined outputs, the system is strictly passive from the laser motion and power. To avoid over-reliance on the model, the steady-state laser speed and power are adaptively updated, resulting in an integral-like update law for the feedforward. Moreover, the heat transfer coefficient to the ambient may be uncertain, and can also be adaptively updated. The final form of the control law combines passive error temperature field feedback with adaptive feedforward and parameter estimation. The closed-loop asymptotical stability is shown using the Lyapunov arguments, and the controller performance is demonstrated in a simulation.

Published: January 2020

Abstract
Liquid metal embrittlement (LME) is one of the severe problems of Zn-coated steel in resistance spot welding (RSW). Hence, proper welding schedules for Zn-coated steel are of practical interest. RSW involves a complex interaction between electrical, thermal, and mechanical phenomena. Identification and integration of all these governing physics are almost impossible by performing simple experiments. Hence, phenomenological modeling of RSW has gained a significant attention in the recent past. The complexity of the physical process introduced by the dynamic nature of contact resistance brings challenges for the model. A simplified but effective modeling approach of RSW is proposed where attention is focused on the evaluation of the thermal field using the finite element (FE) method. The interaction of the mechanical and electrical field is performed by the dynamic variation of the contact area, stress concentration, and non-uniform current density distribution in a semi-analytical model. These internal variables of the model are incorporated through the scaling of the governing parameters by the dependence of the transient and converged temperature field within a time step. The transient-dynamic contact resistance is detached from the measurement of total resistance and mapped adaptively by the implicit scheme within a time step of the numerical model. The transient development of the nugget is investigated for dual-phase steel (DP980) with an interrupted test of the dynamic resistance curve. The FE model is validated with experimentally measured results at different process conditions. The characterization of the thermal history from the model relatively identifies the LME phenomena and suggests corresponding modification of the welding schedule.

IntroductionIndividuals with type 1 diabetes (T1D) present with diverse body weight status and degrees of glycemic control, which may warrant different treatment approaches. We sought to identify subgroups sharing phenotypes based on both weight and glycemia and compare characteristics across subgroups.Research design and methodsParticipants with T1D in the SEARCH study cohort (n=1817, 6.0–30.4 years) were seen at a follow-up visit >5 years after diagnosis. Hierarchical agglomerative clustering was used to group participants based on five measures summarizing the joint distribution of body mass index z-score (BMIz) and hemoglobin A1c (HbA1c) which were estimated by reinforcement learning tree predictions from 28 covariates. Interpretation of cluster weight status and glycemic control was based on mean BMIz and HbA1c, respectively.ResultsThe sample was 49.5% female and 55.5% non-Hispanic white (NHW); mean±SD age=17.6±4.5 years, T1D duration=7.8±1.9 years, BMIz=0.61±0.94, and HbA1c=76±21 mmol/mol (9.1±1.9)%. Six weight-glycemia clusters were identified, including four normal weight, one overweight, and one subgroup with obesity. No cluster had a mean HbA1c <58 mmol/mol (7.5%). Cluster 1 (34.0%) was normal weight with the lowest HbA1c and comprised 85% NHW participants with the highest socioeconomic position, insulin pump use, dietary quality, and physical activity. Subgroups with very poor glycemic control (ie, ≥108 mmol/mol (≥12.0%); cluster 4, 4.4%, and cluster 5, 7.5%) and obesity (cluster 6, 15.4%) had a lower proportion of NHW youth, lower socioeconomic position, and reported decreased pump use and poorer health behaviors (overall p<0.01). The overweight subgroup with very poor glycemic control (cluster 5) showed the highest lipids and blood pressure (p<0.01).ConclusionsThere are distinct subgroups of youth and young adults with T1D that share weight-glycemia phenotypes. Subgroups may benefit from tailored interventions addressing differences in clinical care, health behaviors, and underlying health inequity.

IntroductionThe prevalence of diabetes in schizophrenia is twice that in the general population, but there are few reliable predictors of which individuals will develop glucose dysregulation.ObjectiveTo test if abnormal birth weight (either too low or too high) and parental diabetes, both variables that can be ascertained in the clinic, can predict diabetes onset in patients with schizophrenia.Research design and methodsElectronic records of a cohort of 190 clozapine-treated patients (37% treated for more than 20 years) and Cox regression survival analysis (with any type of glucose dysregulation as the event) to account for differences in length of treatment before the event and age at clozapine treatment initiation.ResultsAge at clozapine initiation (Exp(B)=1.098; p<0.001), family history of diabetes (Exp(B)=2.299; p=0.049) and birth weight2(Exp(B)=0.999; p=0.013) were significant predictors of glucose dysregulation onset, while gender was not (Exp(B)=0.1.350; p=0.517). Among individuals with 10 years of follow-up, 80% of those with both abnormal birth weight and a family history of diabetes developed diabetes compared with 56% with only abnormal birth weight, 40% with only a family history of diabetes and 20% in those with neither.ConclusionsSince 48% of cases had at least one risk factor and 6% had both risk factors, there is a substantial proportion of patients for whom preventive strategies could be implemented.
Short-term plasticity in glomerular inhibitory circuits shapes olfactory bulb output
Authors: Zhou Fu-Wen , Shao Zuo-Yi , Shipley Michael T. , Puche Adam C. 
Published: January 2020

Short-term plasticity is a fundamental synaptic property thought to underlie memory and neural processing. The glomerular microcircuit comprises complex excitatory and inhibitory interactions and transmits olfactory nerve signals to the excitatory output neurons, mitral/tufted cells (M/TCs). The major glomerular inhibitory interneurons, short axon cells (SACs) and periglomerular cells (PGCs), both provide feedforward and feedback inhibition to M/TCs and have reciprocal inhibitory synapses between each other. Olfactory input is episodically driven by sniffing. We hypothesized that frequency-dependent short-term plasticity within these inhibitory circuits could influence signals sent to higher-order olfactory networks. To assess short-term plasticity in glomerular circuits and MC outputs, we virally delivered channelrhodopsin-2 (ChR2) in glutamic acid decarboxylase-65 promotor (GAD2-cre) or tyrosine hydroxylase promoter (TH-cre) mice and selectively activated one of these two populations while recording from cells of the other population or from MCs. Selective activation of TH-ChR2-expressing SACs inhibited all recorded GAD2-green fluorescent protein(GFP)-expressing presumptive PGC cells, and activation of GAD2-ChR2 cells inhibited TH-GFP-expressing SACs, indicating reciprocal inhibitory connections. SAC synaptic inhibition of GAD2-expressing cells was significantly facilitated at 5–10 Hz activation frequencies. In contrast, GAD2-ChR2 cell inhibition of TH-expressing cells was activation-frequency independent. Both SAC and PGC inhibition of MCs also exhibited short-term plasticity, pronounced in the 5–20 Hz range corresponding to investigative sniffing frequency ranges. In paired SAC and olfactory nerve electrical stimulations, the SAC to MC synapse was able to markedly suppress MC spiking. These data suggest that short-term plasticity across investigative sniffing ranges may differentially regulate intra- and interglomerular inhibitory circuits to dynamically shape glomerular output signals to downstream targets.NEW & NOTEWORTHY Short-term plasticity is a fundamental synaptic property that modulates synaptic strength based on preceding activity of the synapse. In rodent olfaction, sensory input arrives episodically driven by sniffing rates ranging from quiescent respiration (1–2 Hz) through to investigative sniffing (5–10 Hz). Here we show that glomerular inhibitory networks are exquisitely sensitive to input frequencies and exhibit plasticity proportional to investigative sniffing frequencies. This indicates that olfactory glomerular circuits are dynamically modulated by episodic sniffing input.

AbstractPurpose:The purpose of this study was to evaluate antigen experienced T cells in peripheral blood lymphocytes (PBL) for responses to p53 neoantigens.Experimental Design:PBLs from patients with a mutated TP53 tumor were sorted for antigen-experienced T cells and in vitro stimulation (IVS) was performed with p53 neoantigens. The IVS cultures were stimulated with antigen-presenting cells expressing p53 neoantigens, enriched for 41BB/OX40 and grown with rapid expansion protocol.Results:T-cell responses were not observed in the PBLs of 4 patients who did not have tumor-infiltrating lymphocyte (TIL) responses to mutated TP53. In contrast, 5 patients with TIL responses to mutated TP53 also had similar T-cell responses in their PBLs, indicating that the PBLs and TILs were congruent in p53 neoantigen reactivity. CD4+ and CD8+ T cells were specific for p53R175H, p53Y220C, or p53R248W neoantigens, including a 78% reactive T-cell culture against p53R175H and HLA-A*02:01. Tracking TCRB clonotypes (clonality, top ranked, and TP53 mutation-specific) supported the enrichment of p53 neoantigen–reactive T cells from PBLs. The same T-cell receptor (TCR) from the TIL was found in the IVS cultures in three cases and multiple unique TCRs were found in another patient. TP53 mutation–specific T cells also recognized tumor cell lines bearing the appropriate human leukocyte antigen restriction element and TP53 mutation, indicating these T cells could recognize processed and presented p53 neoantigens.Conclusions:PBL was a noninvasive source of T cells targeting TP53 mutations for cell therapy and can provide a window into intratumoral p53 neoantigen immune responses.See related commentary by Olivera et al., p. 1203
Direct torque control of IM using PID controller
Authors: Abdullah Ali Najim , Ali Mohammed Hasan 
Published: January 2020

Direct torque control "DTC" technique is one of a high performance control system of an AC motor drive, which was proposed after the vector oriented control scheme during the resent 25 years. It has been developed rapidly for its concise system scheme, transient and dynamic performance. The DTC mechanism consists of voltage vector selection table, two hysteresis comparators and two estimators one for stator flux and another for electromagnetic torque. DTC is directly control torque and flux by using Voltage Source Inverter VSI, space vector and stator flux orientation and indirect speed regulated. A several control techniques can be used for improving the torque and flux performance.
In this paper, the DTC with Proportional-Integral-Derivative (PID) controller used to improve the starting and dynamic performance of asynchronous motor AM, which gives good torque and flux response, best speed control and also minimize the unacceptable torque ripple. The mathematical model of DTC with PID controller of 3-phase induction motor IM are simulated under Matlab-Simulink. Therefore, the DTC based on PID controller has good performance of IM compared to classical DTC for starting, running state and also during change in load.
Jesus als Typos der Mannhaftigkeit
Authors: Weidemann Hans-Ulrich 
Published: January 2020

Abstract
This article examines the way Cyril of Alexandria interprets the Passion narrative in his commentary on the Gospel of John. It argues that besides the doctrinal, christological focus of his exegesis Cyril is concerned with a second issue: the contested masculinity of Jesus and his followers during the events of the Passion. This concern becomes clear when Cyril designates the cross-bearing Jesus as “the type of manly courage” (typos andreías). Following a survey of the current historical masculinity studies, the article examines Cyril’s interpretation of such scenes of the Johannine Passion account where Jesus is depicted as being arrested, beaten and flogged, humiliated and finally crucified – i.e., depicted in a way that might seem to contradict antique ideals of manliness. It finally analyzes Cyril’s explanations as to various “unmanly” or “manly” traits of Jesus’ adversaries, especially of the Jews, and of his followers: Peter, his beloved disciple and his Mother.

Forms of Representation of Propositional Argument in Bulgarian, Polish and Russian Expressions Based on the Mental PredicateThis article offers a discussion of Bulgarian, Polish and Russian mental verbs from the perspective of syntactic valence. The author examines grammatical forms of propositional argument in sentences with mental verbs which represent predicate-argument structure P (x, q). All syntactic forms in the focus of this study are classified into several patterns: observance, compression and splitting. The author demonstrates that what they involve is analogical reflection of propositional structure, greater or smaller compression of propositional argument, or its segmentation and doubling of syntactic position. The author examines the regularity of implementation of each grammatical form in Bulgarian, Polish and Russian on the basis of relevant quantitative data. Formy reprezentacji argumentu propozycjonalnego w bułgarskich, polskich i rosyjskich zdaniach ufundowanych na predykacie mentalnym Tematem prezentowanego artykułu są bułgarskie, polskie i rosyjskie czasowniki mentalne, badane w perspektywie walencji syntaktycznej. Autor analizuje gramatyczne formy realizacji argumentu propozycjonalnego w zdaniach z czasownikami mentalnymi w pozycji orzeczenia, które reprezentują strukturę predykatowo-argumentową P (x, q). Wszystkie formy syntaktyczne podzielono na kilka typów: przestrzeganie, kompresja i rozszczepienie. Autor pokazuje, że w tym zakresie mamy do czynienia z kalkowaniem struktury propozycjonalno-semantycznej, z mniej lub bardziej intensywną kompresją argumentu propozycjonalnego lub z jego rozczłonkowaniem i podwojeniem pozycji syntaktycznej. Została zbadana regularność realizacji każdej formy gramatycznej w systemie trzech języków. Wnioski są oparte na danych kwantytatywnych.

Semantics of Old Polish Beekeeping Terms: The Case of (po)łazić pszczoły/miód ‘Take Honey from the Bees’ in a Cognitive PerspectiveThis article aims to explain the process of terminologisation of the verb (po)łazić in beekeeping terminology. We present its stages and hypotheses concerning the semantics of the Old Polish term under consideration, including possible event schemas and its non-prepositional syntax. The analysis indicates that the terminologisation of word combinations with the verb (po)łazić in beekeeping terminology: (po)łazić pszczoły/miód ‘take honey from the bees’ involved the process of shifting the semantic dominant and, consequently, changing the event schema (“self-motion schema” → “caused motion schema” or “transfer”). On the level of syntactic analysis, we put forward a hypothesis about the possible origin of the non-prepositional structure generated as a result of transformation of the prepositional phrase: łazić po pszczoły/miód → połazić pszczoły/miód with a general meaning ‘perform the action directed at the singled-out object that changes its location as a result’. Semantyka staropolskich terminów bartniczych – na przykładzie (po)łazić pszczoły/miód – w ujęciu kognitywnym Celem pracy jest wyjaśnienie zjawiska terminologizacji czasownika (po)łazić w użyciu bartniczym – przedstawienie jej etapów oraz hipotez dotyczących semantyki badanego terminu staropolskiego, w tym realizowanych możliwych schematów zdarzeń, oraz jego bezprzyimkowej składni. Analiza pokazuje, że proces terminologizacji badanych połączeń wyrazowych: (po)łazić pszczoły/barć/miód polegał na przesuwaniu się dominanty znaczeniowej, a w konsekwencji zmiany schematu zdarzenia (samoprzemieszczanie → powodowanie ruchu lub przekazywanie). Z kolei w analizie składniowej badanego terminu postawiona została hipoteza o możliwym pochodzeniu konstrukcji bezprzyimkowej z przekształcenia formacji z wyrażeniem przyimkowym: łazić po pszczoły/ miód → połazić pszczoły/miód o znaczeniu ogólnym ‘wykonać daną czynność ukierunkowaną na wyróżniony obiekt, który w wyniku tej czynności zmienia swoją lokalizację’.
