NEUROTEC I: Neuro-inspired Artificial Intelligence Technologies for the Electronics of the Future (2022)

The field of neuromorphic computing is approaching an era of rapid adoption driven by the urgent need of a substitute for the von Neumann computing architecture. NEUROTEC I: “Neuro-inspired Artificial Intelligence Technologies for the Elec-tronics of the Future” project is an initiative sponsored by the German Federal Ministry of Education and Research (BMBF for its initials in German), that aims to effectively advance the foundations for the utilization and exploitation of neuromorphic computing. NEUROTEC I stands at its successful “final stage” driven by the collaboration from more than 8 institutes from the Jiilich Research Center and the RWTH Aachen University, as well as collaboration from several high-tech industry partners. The NEUROTEC I project considers the field interplay among materials, circuits, design and simulation tools. This paper provides an overview of the project's overall structure and discusses the scientific achievements of its individual activities.

The hydrophobic domain of cytochrome b5 is capable of anchoring beta-galactosidase in Escherichia coli membranes (1989)

Cytochrome b5 is inserted posttranslationally into membranes in vivo and spontaneously into liposomes in vitro by a short carboxyl-terminal hydrophobic membrane-anchoring sequence. DNA corresponding to this hydrophobic sequence has been synthesized, and two gene fusions with the Escherichia coli enzyme beta-galactosidase have been constructed by locating the hydrophobic domain in one case at the EcoRI site near the C terminus and in the other at the normal C terminus of the enzyme. The latter fusion protein was enzymatically active, having approximately 50% of the specific activity of beta-galactosidase, and cells expressing this protein grew normally with lactose as the sole carbon source. Both fusion proteins were localized to the E. coli inner membrane, converting beta-galactosidase from a cytoplasmic enzyme to a membrane-associated enzyme. The hydrophobic domain of cytochrome b5 therefore contains the information required to target polypeptides containing this domain to the membrane. Use of the cytochrome b5 hydrophobic peptide, either alone or in conjunction with other localizing sequences such as signal sequences, provides a general procedure for associating proteins with membranes. Polypeptides bearing this hydrophobic peptide may have considerable use as pharmaceuticals when associated with liposomes or cellular membranes.

6.15선언 이후 남북 경협현황, 경협기금 운용평가 및 정책과제 (2007)

역사적인 6.15 선언의 성과로 남북경협은 새로운 전기가 마련되었다. 정상회담 후 남북 경제협력은 그동안의 임의적이며 비제도적인 단계에서 벗어나 정상적이며 제도적인 단계로 발전되어 왔다. 정상회담 후 연이어 열린 남북 장관급 회담에서는 개성공단, 경의선 도로, 철도의 연계 등 3대 남북경협사업에 대한 합의가 이루어졌고 또한 투자 보장, 청산결제 등 남북경협을 위한 4대 기본협정에 대한 합의 역시 이루어진다. 그리고 남북경제협력 추진위의 구성에 합의함으로써 남북 경협의 원활한 추진과 남북경협의 제도화를 위한 기초를 놓게 되었다. 6.15 선언 후 남북경제관계의 제도화에 힘입어 남북 경제협력은 질과 양에 있어서 많은 발전을 해왔다. 지난 7년간 남북관계는 지속적으로 발전하여 물적 인적 교류가 대폭 확대 되었다. 그 동안 백만 명 이상의 남한 주민들이 금강산을 방문했으며 남북 간 교역액은 20006년에는 13억불 수준으로 확대되어 1991년 1억불 수준에서 13배 이상의 양적 증가를 가져왔다. 또한 남북경협도 본격화 되어 그 동안 정부차원에서 추진되어온 대규모 사업인 3대 경협사업도 본 궤도에 진입하였다. 개성공단에는 분단 이후 처음으로 남북 상설 협의 사무소인 남북경협 협의사무소가 개소되고 만여 명의 북한근로자들이 남한기업에서 일하고 있다. 또한 최근에는 남북철도의 시험운행이 이루어져 남북철도 도로의 연결이 이루어졌다. 이러한 남북 경제관계의 발전에 따라 남북 경협은 임가공 등 남쪽에 의한 일방적 경제교류의 형태에서부터 남북합작 그리고 경공업 광물자원개발 등 유무상통 형 교류로 확대되고 있다. 한편 북한도 6. 15 선언 이후 7.1 경제관리 개선 조치(2002년)와 경제특구 건설 등 대폭적인 개혁 개방 조처를 추진하고 있다. 국내적으로는 남북 경제교류의 활성화에 따른 조처로 남북관계 발전에 관한 법률이 제정되어 남북경협이 국민적 합의하에 지속적으로 추진될 수 있는 법적 토대가 마련되었다. 그러나 남북경협의 활성화를 위해서는 해결해야 할 과제도 많이 있는데, 그 중 가장 중요한 것은 재원 조달 방안을 마련하는 것이다. 북한의 사회간접 자본 건설지원을 위해서는 막대한 자금이 소요될 것으로 보이는데 이에 필요한 재원을 우리 정부가 독자적으로 조달 하는 데는 한계가 있다. 따라서 다양한 재원조달 방안을 마련해야 하며 특히 외국자본의 도입 방안을 적극적으로 강구해야 한다. 그리고 부족한 자금의 효율적 사용을 위해서는 남북협력 기금의 관리 운용체계의 개편이 필요하다.
Optical Dissection of Odor Information ProcessingIn VivoUsing GCaMPs Expressed in Specified Cell Types of the Olfactory Bulb (2013)

Understanding central processing requires precise monitoring of neural activity across populations of identified neurons in the intact brain. In the present study, we used recently optimized variants of the genetically encoded calcium sensor GCaMP (GCaMP3 and GCaMPG5G) to image activity among genetically and anatomically defined neuronal populations in the olfactory bulb (OB), including two types of GABAergic interneurons (periglomerular [PG] and short axon [SA] cells) and OB output neurons (mitral/tufted [MT] cells) projecting to the piriform cortex. We first established that changes in neuronal spiking can be related accurately to GCaMP fluorescence changes via a simple quantitative relationship over a large dynamic range. We next used in vivo two-photon imaging from individual neurons and epifluorescence signals reflecting population-level activity to investigate the spatiotemporal representation of odorants across these neuron types in anesthetized and awake mice. Under anesthesia, individual PG and SA cells showed temporally simple responses and little spontaneous activity, whereas MT cells were spontaneously active and showed diverse temporal responses. At the population level, response patterns of PG, SA, and MT cells were surprisingly similar to those imaged from sensory inputs, with shared odorant-specific topography across the dorsal OB and inhalation-coupled temporal dynamics. During wakefulness, PG and SA cell responses increased in magnitude but remained temporally simple, whereas those of MT cells changed to complex spatiotemporal patterns reflecting restricted excitation and widespread inhibition. These results suggest multiple circuit elements with distinct roles in transforming odor representations in the OB and provide a framework for further study of early olfactory processing using optical and genetic tools.
New TFA-Free Cleavage and Final Deprotection in Fmoc Solid-Phase Peptide Synthesis: Dilute HCl in Fluoro Alcohol (2012)

A novel method for cleaving from resin and removing acid-labile protecting groups for the Fmoc solid-phase peptide synthesis is described. 0.1 N HCl in hexafluoroisopropanol or trifluoroethanol cleanly and rapidly removes the tert-butyl ester and ether, Boc, trityl, and Pbf groups and cleaves the common resin linkers: Wang, HMPA, Rink amide, and PAL. Addition of just 5-10% of a hydrogen-bonding solvent considerably retards or even fully inhibits the reaction. However, a non-hydrogen-bonding solvent is tolerated.
Date Palm Pollen Grains as a Potential Manager for Male Sub-fertility: A Clinical Trial (2020)

Medicinal plants are identified and used throughout human history; it has a great economic value especially in drugs discovery. Date palm pollen (DPP) is used traditionally in Sudan for treating sub-fertile male patients. Male infertility is heterogeneous group of disorders, most of them are idiopathic. This study is aimed to investigate the role of pharmaceutical preparation of DPP in amelioration of male sub fertility with detection of any possible adverse effects on the major body system functions, through blood picture, liver enzymes and kidney function. This study is a single group pretest-posttest experimental prospective comparative self-control. Sub-fertile men with Idiopathic oligoasthenozoospermia or azoospermia were received 500 mg capsules of DPP twice daily for three months after conducting their safety profiles to detect any toxic effects on hematological, hepatological and nephrological functions, Blood samples were taken from the patients for serum level of FSH (for azoospermic patients), FSH and Testosterone (for oligoasthenozoospermic patients). Finally, Semen sample have been obtained for computerized assisted semen analysis (CASA) report I and II. DPP administration induced significant increase (p≤0.001) in testosterone level (in oligoasthenozoospermic patients) and FSH level (in azoospermic patients). DPP induced significant changes (p≤0.001) towards improvement in the total and progressive sperm motility percentages measured in oligoasthenozoospermic patients by CASA dynamic analysis report I and II. The toxicological studies for DPP approved their safety use in human.

Association between Neighborhood Socioeconomic Status and Executive System Activation in Youth (2021)

ABSTRACT Low socioeconomic status has been shown to have detrimental effects on cognitive performance, including working memory (WM). As executive systems that support WM undergo functional neurodevelopment during adolescence, environmental stressors at both individual and community levels may have a particularly strong impact on cognitive outcomes. Here, we sought to examine how neighborhood socioeconomic status (SES) impacts task-related activation of the executive system during adolescence, and to determine whether this effect mediates the relationship between neighborhood SES and WM performance. To address these questions, we studied 1,158 youths (age 8-22) that completed a fractal n -back WM task during fMRI at 3T as part of the Philadelphia Neurodevelopmental Cohort. We found that higher neighborhood SES was associated with greater activation of the executive system to WM load, including the bilateral dorsolateral prefrontal cortex, posterior parietal cortex, and precuneus. These associations remained significant when controlling for related factors like parental education and exposure to traumatic events. Furthermore, high dimensional multivariate mediation analysis identified two distinct patterns of brain activity within the executive system that significantly mediated the relationship between neighborhood SES and task performance. Together, these findings underscore the importance of the neighborhood environment in shaping executive system function and WM in youth.
Effect of olive by-products feed supplementation on physicochemical and microbiological profile of Provola cheese (2023)

Looking at the physicochemical variable's profiles, a higher content of unsaturated fatty acids, polyunsaturated fatty acid, and conjugated linoleic acids as well of proteins were observed in experimental cheese samples, indicating the beneficial effect of dietary supplementation. Furthermore, based on volatilome composition, a clear cluster separation between control and experimental cheeses was obtained, mainly related to terpenes degradation, able of influencing their aroma and taste. Microbiological results showed a decrease of some spoilage related microbial groups in experimental cheeses, probably due to the inhibitory effect exerted by polyphenols compounds, that contrarily did not affect the core taxa of all cheese samples. This paper confirmed the promising utilization of olive by-product in farming practices to obtain more sustainable and safe dairy food products with lower environmental impact, mainly in Sicily and Mediterranean area, where waste disposal poses serious environmental and economic problems.
Supporting Collaboration Awareness with Real-Time Visualization of Development Activity (2010)

In the context of multi-developer projects, where several people are contributing code, developers must deal with concurrent development. Collaboration among developers assumes a fundamental role, and failing to address it can result, for example, in shipping delays. We argue that tool support for collaborative software development augments the level of awareness of developers, and consequently, help them to collaborate and coordinate their activities. In this context, we present an approach to augment awareness by recovering development information in real time and broadcasting it to developers in the form of three lightweight visualizations. Scamp, the Eclipse plug-in supporting this, is part of our Syde tool to support collaboration. We illustrate the usage of Scamp in the context of two multi-developer projects.
Size‐Dependent Isotropic/Nematic Phase Transition Behavior of Liquid Crystalline Peptide Nanowires (2009)

Abstract We present size‐tunable assemblies of peptide nanowires and study their liquid crystalline phase behavior. An aromatic peptide molecule of diphenylalanine was rapidly assembled into one‐dimensional nanowires, whose sizes were tunable according to the initial concentration of diphenylalanine in the preparing solution. The stable dispersion of peptide nanowires in an organic solvent exhibited colloidal nematic liquid crystalline phases. The liquid crystalline phase transition was governed by the repulsive electrostatic interaction among peptide nanowires as well as their shape anisotropy and polydispersity. Our work provides an interesting model system to investigate the liquid crystalline phase behaviors of a biomolecular assembly in terms of its assembled morphology and intermolecular interactions. magnified image
PDGF α-receptor is unresponsive to PDGF-AA in aortic smooth muscle cells from the NG2 knockout mouse (1999)

A line of null mice has been produced which fails to express the transmembrane chondroitin sulfate proteoglycan NG2. Homozygous NG2 null mice do not exhibit gross phenotypic differences from wild-type mice, suggesting that detailed analyses are required to detect subtle alterations caused by the absence of NG2. Accordingly, dissociated cultures of aortic smooth muscle cells from null mice were compared to parallel cultures from wild-type mice for their ability to proliferate and migrate in response to specific growth factors. Both null and wild-type smooth muscle cells exhibited identical abilities to proliferate and migrate in response to PDGF-BB. In contrast, only the wild-type cells responded to PDGF-AA in both types of assays. NG2 null cells failed to proliferate or migrate in response to PDGF-AA, implying a defect in the signaling cascade normally initiated by activation of the PDGF (alpha)-receptor. In agreement with this idea, activation of the extracellular signal-regulated kinase (ERK) in response to PDGF-AA treatment occured only in wild-type cells. Failure to observe autophosphorylation of the PDGF (alpha)-receptor in PDGF-AA-treated null cells indicates that the absence of NG2 causes a defect in signal transduction at the level of (alpha)-receptor activation.
Model-guided Geosteering for Horizontal Drilling (2009)

Horizontal drilling is an important development in the petroleum industry and it relies heavily on guiding the drill bit with the aid of sonic logging, i.e. geosteering. The quality of sonic imaging depends heavily on the effective suppression of borehole waves and enhancement of weak reflection signal. To this end, we propose an approach to image the near-borehole structure using acoustic logging data. We model the borehole wave propagation using log-derived velocities. The modeled borehole waves are removed from the raw data, leaving reflected signals for imaging interfaces. We tested this method with three sets of data. First we calculated synthetic waveforms for a horizontal well with an interface parallel to the borehole using the 3D finite difference method. The processing result with our method clearly shows the parallel reflecting interface. Next, we conducted an ultrasonic laboratory measurement in a borehole with a parallel Lucite-water boundary. In this case, the interface was also visible in the final image. Finally, we applied this method to a field dataset. In the field dataset, the acoustic logging data were continuously recorded along the well, which enabled us to reject the borehole modes in both common shot gather and common offset gather. The large amount of common offset gather data also allowed us to apply migration to the data. The migrated image of the near-borehole structure is in good agreement with available geological and petrophysical information of that field.

Noninvasive Bioluminescence Imaging of Normal and Spontaneously Transformed Prostate Tissue in Mice (2006)

Several transgenic mouse models of prostate cancer have been developed recently that are able to recapitulate many key biological features of the human condition. It would, therefore, be desirable to employ these models to test the efficacy of new therapeutics before clinical trial; however, the variable onset and non-visible nature of prostate tumor development limit their use for such applications. We now report the generation of a transgenic reporter mouse that should obviate these limitations by enabling noninvasive in vivo bioluminescence imaging of normal and spontaneously transformed prostate tissue in the mouse. We used an 11-kb fragment of the human prostate-specific antigen (PSA) promoter to achieve specific and robust expression of firefly luciferase in the prostate glands of transgenic mice. Ex vivo bioluminescence imaging and in situ hybridization analysis confirmed that luciferase expression was restricted to the epithelium in all four lobes of the prostate. We also show that PSA-Luc mice exhibit decreased but readily detectable levels of in vivo bioluminescence over extended time periods following androgen ablation. These results suggest that this reporter should enable in vivo imaging of both androgen-dependent and androgen-independent prostate tumor models. As proof-of-principle, we show that we could noninvasively image SV40 T antigen-induced prostate tumorigenesis in mice with PSA-Luc. Furthermore, we show that our noninvasive imaging strategy can be successfully used to image tumor response to androgen ablation in transgenic mice and, as a result, that we can rapidly identify individual animals capable of sustaining tumor growth in the absence of androgen.

Higher Levels and Blunted Diurnal Variation of Cortisol in Frail Older Women (2008)

Our findings provide the first epidemiological evidence that higher levels and blunted diurnal variation of cortisol may be involved in the vulnerability and clinical presentation observed in frail older women.
Interactive visualization of state transition systems (2002)

A new method for the visualization of state transition systems is presented. Visual information is reduced by clustering nodes, forming a tree structure of related clusters. This structure is visualized in three dimensions with concepts from cone trees and emphasis on symmetry. A number of interactive options are provided as well, allowing the user to superimpose detail information on this tree structure. The resulting visualization enables the user to relate features in the visualization of the state transition graph to semantic concepts in the corresponding process and vice versa.
Developing a More Focal Magnetic Stimulator. Part II (1991)

First, our program for fabricating stimulator coils that are focal is reviewed. These are in the figure-eight shape, where the goal is to make them successively more focal, hence of successively smaller size. Although smaller coils require larger pulse currents, with resulting stress and heat problems, operating prototypes were readily fabricated with circle diameters down to 2.5 cm. However, for smaller diameters, the coil casings were fractured, and new casing techniques are being explored. Second, our program is reviewed for measuring the distribution of current induced in saline tanks by stimulator coils, to determine their focality. A coaxial probe measures the potential difference between two neighboring points in the tank, yielding the local current density. Measurements are presented due to several shapes of tanks and coil configurations. In a spherical tank, results confirm the theory that there can be neither radial current induced anywhere in the sphere nor any current at the sphere center. In tanks approximating a semi-infinite volume and the human limb, arrow-map distributions are shown, due to a commercial "pancake" coil and several figure-eight coils. In the semi-infinite tank, where the distribution can also be computed theoretically, the measured distribution agrees with the computations, thus validating the measurements. In the limb tank, the distribution is compressed and is somewhat more focal than in the semi-infinite tank, depending on the coil orientation.
