Ratio‐adjustable power splitters for array‐compressed parallel transmission

Purpose To implement and validate low‐loss ratio‐adjustable power splitters (RAPS) for array‐compressed parallel transmission (acpTx). Methods In acpTx, a small number of transmit channels drive a larger number of transmit coils, which are connected via an array compression network that implements optimized coil‐to‐channel combinations. Previous networks comprised a bank of power splitters, followed by attenuators to implement the amplitudes of the compression weights for each coil, but this resulted in high power dissipation in the network. Recognizing that an acpTx network need only implement relative attenuations between outputs, a RAPS circuit was developed which combines power splitting and relative attenuation, and has low insertion loss. RAPS circuits were experimentally validated and used to build an array compression network for a one‐channel‐to‐four‐coil spiral acpTx excitation experiment. Results Bench tests showed that the RAPS circuits came within 0.05 dB of the desired output ratios, and power dissipation was approximately 0.5 dB (10%). The spiral excitation experiment showed that the ability to optimally drive four coils with a single channel reduced excitation error by 46% compared to driving one coil, without using attenuators in the array compression network. Conclusion RAPS circuits enable the construction of low‐loss array compression networks for parallel transmission.

Site of action and biphasic effect of neutral salts in the phosphorylase kinase reaction

The inhibition of phosphorylase kinase catalytic activity by 0.1 M neutral salts was predicted by the Hofmeister series of anions. The site of action of the salts was determined by the following evidence to be on the phosphorylase kinase molecule directly, rather than on its protein substrate. (1) Nonactivated kinase was more sensitive to salt inhibition than the activated form. (2) Ca2+ partially overcame the inhibition of nonactivated kinase. (3) Inhibition by Cl- occurred with either phosphorylase or a tetradecapeptide containing the convertible seryl residue as substrate. (4) Phosphorylation of nonactivated phosphorylase kinase by protein kinase was markedly inhibited by NaNO3, but this salt had little effect on the phosphorylation of histone by protein kinase. The influence of neutral salts on phosphorylase kinase activity was biphasic. Although activity was inhibited at low salt concentrations, it actually was stimulated as the salt concentration was increased. A similar biphasic response to various salt concentrations was observed in the velocities of autophosphorylation of phosphorylase kinase. The lag in the rate of product formation seen during the activity assay was less pronounced at inhibitory salt concentrations and was abolished at stimulatory salt concentrations. How the influence of salts relates to autophosphorylation and the lag is considered.

Numerical Experiments for Darcy Flow on a Surface Using Mixed Exterior Calculus Methods

There are very few results on mixed finite element methods on surfaces. A theory for the study of such methods was given recently by Holst and Stern, using a variational crimes framework in the context of finite element exterior calculus. However, we are not aware of any numerical experiments where mixed finite elements derived from discretizations of exterior calculus are used for a surface domain. This short note shows results of our preliminary experiments using mixed methods for Darcy flow (hence scalar Poisson's equation in mixed form) on surfaces. We demonstrate two numerical methods. One is derived from the primal-dual Discrete Exterior Calculus and the other from lowest order finite element exterior calculus. The programming was done in the language Python, using the PyDEC package which makes the code very short and easy to read. The qualitative convergence studies seem to be promising.

Adsorption of Small Molecules on Cu<sub>3</sub>(btc)<sub>2</sub> and Cu<sub>3–<i>x</i></sub>Zn<sub><i>x</i></sub>(btc)<sub>2</sub> Metal–Organic Frameworks (MOF) As Studied by Solid-State NMR

Static and MAS 13C NMR techniques are used to investigate the interaction of CO and CO2 molecules with the host structure of the MOFs Cu3(btc)2 and Cu2.97Zn0.03(btc)2. A defined amount of 13C-enriched molecules per copper atom was adsorbed. The 13C chemical shift anisotropy and isotropic chemical shift were studied over a temperature range from 10 to 353 K. Already above 30 K an isotropic line for CO is found superimposed to the solidlike spectra belonging to the majority of adsorbed CO molecules. For adsorbed CO2 an isotropic line can be detected above 70 K. This observation reflects differences in the local motion of both molecules. At high temperatures it is found that CO is desorbed more easily from the MOF framework in comparison to CO2. This is in agreement with conclusions derived from desorption measurements on Cu3(btc)2. From the temperature dependence of the chemical shift for adsorbed CO2 molecules (measured by means of 13C MAS NMR between 213 and 353 K) and from the deconvolution of the overlapping 13C NMR lines for adsorbed CO molecules (between 180 and 323 K), the activation energy for the local motion of the adsorbed molecules was determined as 3.3 and 6.1 kJ/mol, respectively. Additionally, the motion is accompanied by a partial desorption of the adsorbed species.

Quantum mechanical image potential theory

We present a quantum-mechanical image-potential theory by determining analytically the Kohn-Sham (KS) exchange-correlation potential ${v}_{\mathrm{xc}}(z)$ in the classically forbidden region of the metal-vacuum interface. The asymptotic structure of the image potential is determined to be $\ensuremath{-}({\ensuremath{\alpha}}_{KS,x}+1/4)/z,$ where ${\ensuremath{\alpha}}_{KS,x}$ depends upon the Fermi energy and barrier height of the metal. The structure is obtained from exact expressions derived for ${v}_{\mathrm{xc}}(\mathbf{r})$ in the asymptotic region in terms of the electron self-energy. The KS exchange potential is determined as ${v}_{x}(z)\ensuremath{\sim}\ensuremath{-}{\ensuremath{\alpha}}_{KS,x}/z,$ thereby confirming previous work. The correlation part of the self-energy employed is that of the plasmon-pole approximation, and leads to the KS correlation potential ${v}_{c}(z)\ensuremath{\sim}\ensuremath{-}1/(4z).$ The quantum image potential derived therefore, differs from the commonly accepted classical form of $\ensuremath{-}1/(4z).$ The import of this result to both the theory of image states and the density-functional theory is also discussed.

microRNA-9-5p protects liver sinusoidal endothelial cell against oxygen glucose deprivation/reperfusion injury

Abstract Background Maintenance of the function and survival of liver sinusoidal endothelial cells (LSECs) play a crucial role in hepatic ischemia/reperfusion (I/R) injury, a major cause of liver impairment during the surgical treatment. Emerging evidence indicates a critical role of microRNAs in I/R injury. This study aims to investigate whether miR-9-5p exerts a protective effect on LSECs. Methods We transfected LSECs with miR-9-5p mimic or mimic NC. LSECs were treated with oxygen and glucose deprivation (OGD, 5% CO 2 , and 95% N 2 ), followed by glucose-free Dulbecco’s modified Eagle’s medium (DMEM) medium for 6 h and high glucose (HG, 30 mmol/L glucose) DMEM medium for 12 h. The biological role of miR-9-5p in I/R-induced LSEC injury was determined. Results In the in vitro model of OGD/HG injury in LSECs, the expression levels of miR-9-5p were significantly downregulated, and those of CXC chemokine receptor-4 (CXCR4) upregulated. LSEC I/R injury led to deteriorated cell death, enhanced oxidative stress, and excessive inflammatory response. Mechanistically, we showed that miR-9-5p overexpression significantly downregulated both mRNA and protein levels of CXCR4, followed by the rescue of LSECs, ameliorated inflammatory response, and deactivation of pro-apoptotic signaling pathways. Conclusions miR-9-5p promotes LSEC survival and inhibits apoptosis and inflammatory response in LSECs following OGD/HG injury via downregulation of CXCR4.

Support Revisited

In the evolutionary development of the theory of social work practice, the concept of "support" has consistently been given attention. Ideas about support in terms of aims, effects, methods, and techniques have changed over time as the profession has striven to update its thinking. Support is currently viewed as a viable helping means in work with individuals, families, groups, and communities. The social worker may be the primary provider of support through the professional relationship and by enlisting environmental resources. Likewise, groups may provide support to members, and helping networks in the family and community may become useful support systems.

Demolished in 1807, the church was significant within its Venetian context, but its importance has largely been forgotten. Through their historical reconstruction, based on analyses of archival plans and elevations, illustrated representations, written descriptions and inscriptions, and theoretical treatises, Huffman and Dundas demonstrate the methodological processes of 3-D modeling and the interpretive value of the resulting models for the study of architectural and urban histories. In addition, their work on San Geminiano enables a reevaluation of this historically important yet now lost structure's architecture and its relationship to the space of Piazza San Marco—the political center, socioeconomic nexus, and ceremonial entry point of Venice.

Life Cycle Assessment of CO2 Emissions of Online Music and Videos Streaming in Japan

In this study, we analyzed the CO2 emissions of online music and video streaming services, as one of the digital contents, in Japan using life cycle assessment. As a system boundary of online music and video streaming, processes such as data center construction and server manufacturing, usage of communication networks and internet communication technology devices (personal computers (PCs) and smartphones), and disposal of data centers and servers were considered. Data were collected using statistical and online surveys, and CO2 emissions per 1 MB of communication volume were calculated. One of the results revealed that the lifecycle CO2 emissions of listening to online music using PCs and smartphones were 5.88 × 10−4 and 1.43 × 10−4 kg-CO2/MB, respectively. The overall CO2 emissions for domestic music and video streaming services in 2019 was 921 thousand t-CO2. Online video streaming accounted for 87.7% of the total emissions, which corresponded to approximately 0.23% of domestic CO2 emissions derived from electric power generation.

Making Reshoring Decisions - the Case of a Norwegian Manufacturing Firm

Relocating activities to low-cost countries has been, and still is, a prevalent\nmethod of reducing production costs for manufacturing companies. In recent\nyears, however, many companies have reconsidered this strategy, and started\nto move activities back to their home country. Opportunities to reduce labor\ncosts through automation have certainly contributed to this process.\nThe rationale behind the phenomenon, called \\reshoring", has been discussed\nto a large extent in current research literature. How companies make\nsuch reshoring decisions, on the other hand, is generally under-researched\n(Wiesmann, Snoei, Hilletofth, &amp; Eriksson, 2017). This will be the primary\nfocus of this master's thesis, which aims to understand the role of managerial\naccounting information in reshoring decisions. In order to understand this,\nwe have adopted a single case study methodology. Two embedded cases in\na Norwegian manufacturing company have been studied by interviewing key\ndecision-makers.\nWe found that the company had a rather pragmatic approach to decisionmaking.\nFinancial and non- nancial information were integrated by using a\nmulti-criteria analysis method. This approach did not emphasize the quanti\n cation of qualitative factors, but drew on the experience of decision-makers\nto weigh qualitative factors. Important factors such as proximity to innovation\nenvironments, protection of intellectual property, and e ciency of\ncommunication without cultural boundaries had signi cant in\nuence on the\ndecision. These factors are acknowledged by literature, but this thesis provides\nmore in-depth understanding of how they a ect the reshoring choice.\nA model of the company's decision-making process is presented, and is found\nto have a distinct resemblance to the generic purchasing process de ned by\nvan Weele (2014). For this company, reshoring is a special case of sourcing\nwhere the best option is in the home country.

Deep learning-based identification of patients at increased risk of cancer using routine laboratory markers

Early screening for cancer has proven to improve the survival rate and spare patients from intensive and costly treatments due to late diagnosis. Cancer screening in the healthy population involves an initial risk stratification step to determine the screening method and frequency, primarily to optimize resource allocation by targeting screening towards individuals who draw most benefit. For most screening programs, age and clinical risk factors such as family history are part of the initial risk stratification algorithm. In this paper, we focus on developing a blood marker-based risk stratification approach, which could be used to identify patients with elevated cancer risk to be encouraged for taking a diagnostic test or participate in a screening program. We demonstrate that the combination of simple, widely available blood tests, such as complete blood count and complete metabolic panel, could potentially be used to identify patients at risk for colorectal, liver, and lung cancers with areas under the ROC curve of 0.76, 0.85, 0.78, respectively. Furthermore, we hypothesize that such an approach could not only be used as pre-screening risk assessment for individuals but also as population health management tool, for example to better interrogate the cancer risk in certain sub-populations.

[Late changes of the testicular tissue in experimental torsion of the spermatic cord (author's transl)].

In three experimental groups and a control group unilateral or bilateral torsion of the testicle were carried out in 195 mature rats. The testicles were retorted at various intervals up to 24 hours. Four weeks and three months following the torsion the retorted as well as the contralateral normal testicles were examined morphologically and histologically. A total testicular torsion is fully reversable after one hour in all cases and after 2 hours in 40% of the cases. The Sertoli cells are destroyed after 6 hours and the Leydig cells after 10 hours. The time causing irreversable tissue damage therefore appears to be shorter than generally assumed, and the germinative epithelium is reacting faster than the testosterone producing Leydig cells. No changes were noted in the contralateral normal testis.

[Quality of life--demands and reality as a medical parameter versus quality of life as individual reality].

Quality of life (QL) is a term, whose definition extends beyond scientific methods. Even the most accurate description will only be able to represent a part of the reality due to the proviso of only a limited view. For that reason the abandonment of this term, described as "utopical" and "principally remaining in dissent", was called for. This could be countered by the possibilities to use QL as a therapeutic aim, as well as an aid towards finding an individual indication. Alone the demand staged by QL, to take the individuality seriously, and to be the motor for patient oriented medicine, make this term valuable. The definition itself will remain a called instruments have been developed and tuned, their evaluation has not yet been concluded. The acceptance of QL-registration within clinical studies is low, since the individual integration of values compared to the biometric difficulties can hardly be generalized. The aims of QL-research are: the individual focus on the field of projection of QL; a motivation-oriented mode of record; the involvement of QL-registration in form of information and accompaniment; adequate modular techniques including dialogical methods (nondirective interviews); the establishment of a QL-anamnesis towards an extension of the clinical picture; the observance of a possible conflict of roles, the danger of linguistic inaccuracies and misunderstandings, the consideration of a person's privacy.

Parametric analysis of fiber-reinforced laminated momentum wheel rotors

The objective of this study is to analyze the parameters involved in the design of a graphite- reinforced-epoxy rotor, which is made from axi- symmetric laminated concentric rings with interferences. This design is proposed for use in a Momentum Wheel that is used for attitude stabilization of geo-synchrono us satellites. The formulation of the problem is addressed in the domain of the elasticity theory under plane stress conditions. An analytic model is developed by solving the non-homogenous variable- coefficients total differential equilibrium equation using the displacement formulation (Navier's approach). Four parameters of interest are investigated: the number of concentric rings, the amount of radial interferences, reinforcement volume fraction in each ring, and the lamination angle of the fibers in the hoop-radial plane with respect to the global hoop direction of the rings. The parametric analysis shows that the amount of interferences between the neighboring rings should be kept at the minimum values required to keep the rings in contact at maximum operating speeds. The analysis also proves that by increasing the amount of reinforcement volume fraction, the minimum interferences needed can be reduced proportionally. Finally, It was found out that at the required operating high speeds, the graphite fibers should be aligned in the circumferential direction, and the number of rings the rotor consists of should be kept at a minimum.
