We demonstrate the generation of higher-order modulation formats using silicon-based inphase/quadrature (IQ) modulators at symbol rates of up to 100 GBd. Our devices exploit the advantages of silicon-organic hybrid (SOH) integration, which combines silicon-on-insulator waveguides with highly efficient organic electro-optic (EO) cladding materials to enable small drive voltages and sub-millimeter device lengths. In our experiments, we use an SOH IQ modulator with a π-voltage of 1.6 V to generate 100 GBd 16QAM signals...

Traditional psychoanalytic theories of development hold that the adult neurotic can regress, or has already regressed, to the childhood arrests and/or fixations in which his pathology originated. More recent critiques have called this possibility into question. It is unlikely that anyone can roll back the additions and modifications of lifespan development in a full-fledged return to the needs, wishes, and anxieties of childhood. By regression, though, some analysts mean not a full-fledged return to an earlier developmental phase, but a non-phase-specific slip into primitive fantasies and defenses...

Thomas W Wall
The relationship between hypnosis and psychoanalysis has always been complex, and often acrimonious. When Freud abandoned hypnosis as both the foundation of his theory building and his clinical intervention of choice, the two approaches and the theories associated with them have often seemed separated by enormous rifts, theoretical, clinical, and political. Yet throughout their considerable estrangement for over more than a century, each has much to offer to the other. In this contribution, I briefly review efforts by psychoanalysts to conceptualize and understand hypnosis, offer an introduction to the relatively new post-modern intersubjective approach to psychoanalysis, and demonstrates how the relational concepts associated with that perspective can be of significant help in preparing patients for hypnosis, and in crafting interventions geared to the dynamics of the individual patient, which enhance the likelihood of clinical success...

Sigmund Freud developed what became psychoanalysis in the context of his experiences with hypnosis and the treatment of the grand hysterics of his era, conditions largely classified among the dissociative disorders in contemporary systems of diagnosis. He rapidly constructed understandings of the human mind and human distress that replaced the concept of dissociation and a model of pathology that was passive (associated with reduced psychic cohesion), with the paradigm of an active defensive process he termed repression, and an understanding that psychological discomfort was the outcome of intrapsychic conflict...

Hypnosis predates psychoanalysis, when autohypnotic pathologies were identified through the lens of hypnosis, and labeled "hypnoid hysteria" in the language of the day. The broad spectrum of disorders then subsumed under that term is still reflected in ICD-10's subset, "F44-Dissociative (Conversion) Disorders." Freud initially embraced both hypnoid hysteria and hypnosis, but came to abandon hypnosis and, by extension, hypnoid hysteria as well. Since that fateful decision, which I term herein Freud's "Inaugural Category Mistake," references to both hypnosis and hypnoid pathology largely vanished from the psychoanalytic mainstream, thereby neglecting conditions afflicting a significant portion of the mentally ill, and needlessly restricting the therapeutic repertoire of psychoanalysis...

Fetal cardiac intervention (FCI) offers the potential to alter in utero anatomy and physiology. For aortic stenosis with evolving hypoplastic left heart syndrome and pulmonary atresia with intact ventricular septum with evolving hypoplastic right heart syndrome, FCI may result in maintenance of a biventricular circulation, thus avoiding single-ventricle palliation and its attendant complications. In the case of hypoplastic left heart syndrome with intact atrial septum, FCI may ameliorate in utero pathophysiology and portend a more favorable postnatal prognosis...

Lipoblastoma is a rare and benign tumor arising from embryonal fat cells. It is generally diagnosed in children younger than 3 years of age and can occur in the extremities or on the trunk. We present our series of 10 children with lipoblastoma treated at Schneider Children's Medical Center of Israel between 2011 and 2016. Six boys and four girls underwent tumor resection at a median age of 2 years and 3 months (range 5 months to 5.6 years). Locations were trunk (6), groin (2), perineum (1), and omentum (1)...

This article deals with the circulation and early spread of Freudianism in mass culture in Chilean society at the turn of the twentieth century. It documents the first references to Sigmund Freud in the Chilean media, the announcement of Freudian-style self-help classes, the appearance of psychoanalysts as characters in some fantasy novels, and the open lectures on psychoanalysis given by the first juvenile court judge in Santiago, the lawyer Samuel Gajardo Contreras. It explores the expectations projected onto Freudianism by the Chilean elite, and how Freud's theories contributed to a rethinking of childhood, the family and emotional life in Chile from 1920-1950...

Beginning with the quintessentially psychoanalytic tales of Freud, the case history has held a privileged position in the history and practice of psychoanalysis. Psychoanalysts grow up with, grow into, and grow out of these narratives as clinical practitioners. Alongside the representational aspects of these case histories, there is a rhetorical or persuasive force that significantly influences us. The author contends that the theory of narrative and rhetoric can inform the how, the why, and the "so what?" of our relationship to these stories of psychoanalysis...

The surface receptor FcγRIIIA (CD16a) is encoded by the FCGR3A gene and is acquired by human NK cells during maturation. NK cells bind the Fc portion of IgG via CD16a and execute Ab-dependent cell-mediated cytotoxicity, which is critical for the effectiveness of several antitumor mAb therapies. The role of epigenetic regulatory mechanisms controlling transcriptional and posttranscriptional CD16 expression in NK cells is unknown. In this study, we compared specific patterns of DNA methylation and expression of FCGR3A with FCGR3B, which differ in cell type-specific expression despite displaying nearly identical genomic sequences...

We demonstrate an optical distance sensor integrated on a silicon photonic chip with a footprint of well below 1 mm2. The integrated system comprises a heterodyne receiver structure with tunable power splitting ratio and on-chip photodetectors. The functionality of the device is demonstrated in a synthetic-wavelength interferometry experiment using frequency combs as optical sources. We obtain accurate and fast distance measurements with an unambiguity range of 3.75 mm, a root-mean-square error of 3.4 µm and acquisition times of 14 µs...

Optical spectra of signals at the output of semiconductor optical amplifiers (SOA) provide useful insight into amplifier nonlinearities. In this work, we determine the parameters of an analytical SOA model with a pump-probe experiment by evaluating the measured spectra of the pump and probe pulses at the SOA output. The analytical lumped SOA model considers carrier depletion, carrier recovery, spectral hole burning, two-photon absorption, and we include an additional effect termed 'two-photon induced free-carrier absorption', that is responsible for creating an identifiable blue-shifted component in the spectra...

BACKGROUND: Alzheimer's disease (AD) is the most common type of dementia, affecting one in eight adults over 65 years of age. The majority of AD cases are sporadic, with unknown etiology, and only 5% of all patients with AD present the familial monogenic form of the disease. In the present study, our aim was to establish an in vitro cell model based on patient-specific human neurons to study the pathomechanism of sporadic AD. METHODS: We compared neurons derived from induced pluripotent stem cell (iPSC) lines of patients with early-onset familial Alzheimer's disease (fAD), all caused by mutations in the PSEN1 gene; patients with late-onset sporadic Alzheimer's disease (sAD); and three control individuals without dementia...

Objective: Correlation between radiologic structural abnormalities and clinical symptoms in low back pain patients is poor. There is an unmet clinical need to image inflammation in pain conditions to aid diagnosis and guide treatment. Ferumoxytol, an ultrasmall superparamagnetic iron oxide (USPIO) nanoparticle, is clinically used to treat iron deficiency anemia and showed promise in imaging tissue inflammation in human. We explored whether ferumoxytol can be used to identify tissue and nerve inflammation in pain conditions in animals and humans...

The most relevant theories and ideas about the life cycle in the Andes and their relationship with human development and health are presented. The life cycle is not an immutable phenomenon, the number of stages and its meaning is historically and culturally based. A comparative analysis with the theory of Freud and Erikson was made. It is concluded that the contribution of Andean culture focuses on: 1) Each stage of human development is associated with productive and reproductive processes of life in relation, as well as an adequate balance between rights and duties in life in society; 2) The couple is the basic social unit, and not the individual...

REVIEW
Aharon G Freud, Bethany L Mundy-Bosse, Jianhua Yu, Michael A Caligiuri
Natural killer (NK) cells provide protection against infectious pathogens and cancer. For decades it has been appreciated that two major NK cell subsets (CD56bright and CD56dim) exist in humans and have distinct anatomical localization patterns, phenotypes, and functions in immunity. In light of this traditional NK cell dichotomy, it is now clear that the spectrum of human NK cell diversity is much broader than originally appreciated as a result of variegated surface receptor, intracellular signaling molecule, and transcription factor expression; tissue-specific imprinting; and foreign antigen exposure...
